2.	Carlsson, Per, 1951-, et al. (author) National Model for Transparent Vertical Prioritisation in Swedish Health Care 2007 Reports (other academic/artistic)abstract The proposed national model described in this report has been developed by a working group comprised of staff from the National Board of Health and Welfare, the National Centre for Priority Setting in Health Care, and other organisations involved in vertical prioritisation – including the Östergötland County Council, Stockholm County Council, Västra Götaland, the Health Services Region of Southern Sweden, the Swedish Society of Medicine, the Swedish Society of Nursing, and the Swedish Association of Health Professionals. Throughout the process of designing the model, the Swedish Federation of Occupational Therapists and the Swedish Association of Registered Physiotherapists were regularly informed and given opportunities to review and comment on the proposal. Furthermore, the report was reviewed and discussed at a meeting with invited representatives from the other county councils, the Pharmaceutical Benefits Board, and several professional interest groups. Viewpoints were also obtained at a seminar arranged by PrioNet, a network of individuals interested in prioritisation.Potentially, the working model described in Chapter 4 could be used in any context where vertical prioritisation takes place, e.g. activities arranged by the state, county councils, municipalities, hospital departments, and professional groups.This report is designed to be a useful tool for those working on development projects in priority setting. We believe that the contents must be adapted, with the help of relevant examples and some simplifications; to fit the specific needs of different projects or groups. The text must also be adapted to a target group’s knowledge and previous experience in dealing with transparent priority setting. It must be the responsibility of each provider and other affected organisation to adapt the material to the given situation and project. The National Centre for Priority Setting in Health Care, the National Board of Health and Welfare, and others who have participated actively in this effort can be helpful to various target groups in adapting this report.When and how to engage in practically implementing vertical prioritisation are questions that need to be answered at the local level. Primarily, it is the duty of the local authorities/providers to take responsibility for implementation. Professional organisations also play an important role. Public agencies, universities, and knowledge centres should be sources of support for the local authorities/providers.The Riksdag’s resolution on prioritisation served as the foundation for developing the model.Where there are areas of uncertainty in how to translate these guidelines in practice, or where practical implementation might conflict with the principles, we have pointed this out.Our conclusions and proposals are the following:When facing a choice – regardless of whether it involves allocating new resources for different purposes, or to implement cutbacks – it can be advantageous to rank the possible choices in order of priority. In our model, only the relevant options can be ranked by priority. The consequences of this ranking are not obvious at the outset, but can serve as a basis either to allocate more resources or ration by some means.In vertical prioritisation, it is advantageous to organise the prioritization process starting from a general categorisation of health problems/disease groups. As a rule, these categories cover many organisational units/clinical departments, specialties, or professional groups, thus providing a more multidimensional view of the problem. Furthermore, this allows the process to start from a patient/population perspective, which appears to be more goal-oriented than an organisational/staff perspective.That which is ranked, i.e. one of the choices, we refer to as a prioritization object. We suggest that prioritisation objects consist of different combinations of health conditions and interventions.1 When deciding on the appropriate level of detail, the decision must be based on the context in which prioritisation is carried out. A starting point would be to focus on typical cases, large-volumes services, and controversial care.All forms of vertical prioritisation should be based on the ethical principles that the Riksdag decided should apply in prioritising health services. However, these ethical principles must be made known, clarified, and perhaps complemented before they can be applied to practical priority setting. Furthermore, we believe that the Riksdag’s four so-called priority groups should not be part of the model.The human dignity principle, i.e. that all people should have equal value and equal rights to care irrespective of their personal characteristics and function in society, is the undisputed cornerstone in priority setting. When personal characteristics such as age, gender, lifestyle, or function of a group are expressions of the presence of special needs, so that benefits of the interventions are different, these personal characteristics could be addressed in a priority at the group level. Further discussion is needed regarding the question of how external effects (i.e. the effects of an intervention on families and groups other than the individual directly affected by the intervention) should be valued in priority setting.The concept of need in health care includes both the severity level of the condition and the expected benefits of intervention. As a patient, one needs only those interventions that can be expected to yield benefits. Based on this definition of need, a person does not need an intervention that does not improve health and quality of life, i.e. an intervention with no benefit. In such cases, health services have a responsibility to refer people who seek care for some type of problem, to other appropriate services.The Riksdag’s guidelines regarding the cost-effectiveness principle (applied to individual patients) are too limited to provide guidance for vertical prioritisation at the group level. From the outset, the Government’s bill (Priority Setting in Health Care) highlighted the importance of differentiating a cost-effectiveness principle that applied to choices among various interventions for the individual patient (where the principle can be applied as the Commission of Inquiry proposed) and the aim of health services to achieve high cost-effectiveness in health care generally. Here we also refer to the Riksdag’s directive to the Pharmaceutical Benefits Board. In its decisions on subsidising (prioritising) a drug, the Board should determine, e.g. whether the drug is cost effective from a societal perspective, which requires comparing the patient benefits of the drug to its cost. In such decisions, the cost effectiveness should be considered along with the needs and solidarity principle and the human dignity principle.The proposed working model essentially concurs with the working model used by the National Board of Health and Welfare in developing national guidelines. In describing a national working model, it is not possible to include every aspect that might be considered. Hence, one must start from the model and decide which other relevant aspects should be included. For instance, the International Classification on Functioning, Disability, and Health (ICF) can be used as guidance to describe the severity of health conditions.Due to the wealth of variety in outcome measures for different activities, and the limited experience in working with explicit threshold values, we believe would be premature to recommend standardised categories, e.g. risk levels. However, it is important that those working with prioritization describe their reasoning. Primarily, the categories applied by the Swedish Council on Technology Assessment in Health Care (SBU) to grade the scientific evidence of an intervention’s effects should be used. Local prioritisation projects with limited resources at their disposal should describe (text) their appraisal of the scientific evidence and reference the scientific sources used. The strength of evidence should be expressed in numbers only when supporting a conclusion of a systematic review by SBU, or other literature reviews of good quality.Prioritisation projects having access to health economic evaluation should, until further notice, adhere to the approach used by the National Board of Health and Welfare and present cost-effectiveness on a scale from low to very high cost per life-year gained or cost per quality-adjusted life-year. Economic evidence should be presented according to the principles applied by the National Board of Health and Welfare. In local projects with limited resources, or problems in consistently acquiring information on cost effectiveness, we recommend that the authors at least discuss cost effectiveness in cases where the priority ranking would be decisively affected when costs are weighed in.A 10-level ranking list should be used. The ranking list should be complemented by a “don’t do” list for methods that should not be used at all, or not used routinely, and a research and development (R&D) list for methods where the evidence still insufficient to motivate their use in standard practice. In the absence of an objective quantitative/mathematical method, a qualitative method should be used in the appraisal. Here too, we believe that it is not yet possible to establish standard criteria to determine within which ranking level a prioritisation object should fall.Results should be presented as a ranking list. The parameters used as a basis for prioritisation should also be presented in a uniform manner in ranking lists that are shared with other parties. For pedagogic reasons, details concerning language and format need to be adapted to the respective target groups.Thresholds for what constitutes an acceptable coverage of need (care quality, volume, and percentage of the patient group with access to services) a
3.	Carlsson, Per, 1951-, et al. (author) Nationell modell för öppna vertikala prioriteringar inom svensk hälso- och sjukvård 2007 Reports (other academic/artistic)abstract En arbetsgrupp med personer från Socialstyrelsen och PrioriteringsCentrum, andra organisationer som arbetat med vertikala prioriteringar såsom Landstinget i Östergötland, Stockholms läns landsting, Västra Götaland, Södra sjukvårdsregionen, Svenska Läkaresällskapet, Svensk sjuksköterskeförening och Vårdförbundet har tagit fram detta förslag. Förslaget har fortlöpande förankrats hos Förbundet Sveriges Arbetsterapeuter och Legitimerade Sjukgymnasters Riksförbund som kunnat lämna synpunkter på utformningen av odellen.Dessutom har rapporten varit föremål för granskning och diskussion vid ett möte med inbjudna representanter från övriga landsting, Läkemedelsförmånsnämnden och flera yrkesorganisationer. Synpunkter har också inkommit från ett seminarium som arrangerades av PrioNet, ett nätverk av personer med intresse för prioriteringar.Den arbetsmodell som beskrivs i kapitel 4 ska kunna användas i alla sammanhang där vertikala prioriteringar sker såsom aktiviteter som arrangeras av staten, landsting, kommuner, kliniker, professionella grupper eller motsvarande.Rapporten är skriven på ett sådant sätt att den ska kunna användas i första hand som ett stöd till dem som bedriver utvecklingsarbete rörande prioriteringar. Vi tror att innehållet måste anpassas till olika verksamheter eller personalgruppers specifika behov med hjälp av kompletterande exempel och vissa förenklingar. Texten måste givetvis också anpassas till de kunskaper och tidigare erfarenheter som den aktuella målgruppen har när det gäller arbete med öppna prioriteringar. Sådana situations- och verksamhetsanpassade versioner måste det åligga varje sjukvårdshuvudman och andra berörda organisationer att utarbeta. PrioriteringsCentrum, Socialstyrelsen och andra parter som deltagit aktivt i detta arbete kan givetvis vara behjälpliga i arbetet med att bearbeta denna rapport för olika målgrupper.Frågan om när och hur arbetet med vertikala prioriteringar ska bedrivas i praktiken kan också endast besvaras lokalt. Det är i första hand ett nsvar för huvudmännen att ta ansvar för implementeringen. Professionella organisationer har också en viktig roll. Myndigheter, universitet och kunskapscentra ska vara ett stöd till huvudmännen.Utgångspunkten i modellutvecklingen är Riksdagens beslut om prioriteringar. När det finns oklarheter om hur dessa riktlinjer ska omsättas i praktiken eller att praktiken kan förefalla i konflikt med principerna har vi påpekat detta.När man står inför ett val - oavsett om det handlar om att fördela nya resurser till olika ändamål eller att genomföra besparingar - kan det vara en fördel att kunna rangordna tänkbara valmöjligheter i enprioriteringsordning. I vår modell innebär prioritering enbart att de relevanta alternativen rangordnas. Konsekvenserna av denna rangordning är inte på förhand given utan kan ligga till grund såväl för tillskott av resurser som för ransonering av något slag.Vid en vertikal prioritering är det en fördel att organisera prioriteringsarbetet så att det utgår från en grov uppdelning i hälsoproblem/sjukdomsgrupper. En sådan uppdelning innebär i regel att flera organisationsenheter/kliniker, specialiteter eller yrkesgrupper berörs och man får en mer allsidig belysning av problemet. Dessutom utgår man från ett patient/befolkningsperspektiv vilket förefaller mer ändamålsenligt än ett organisatoriskt/personalperspektiv.Det som rangordnas och som någon väljer mellan benämner vi prioriteringsobjekt. Vi föreslår att prioriteringsobjektet utgörs av olika kombinationer av hälsotillstånd och åtgärder1. När det gäller att bestämma en lämplig detaljeringsgrad måste det avgöras utifrån sammanhanget prioriteringar ska göras i. En utgångspunkt är att fokusera på typfall, vård som representerar stor volym och kontroversiell vård.Alla former av vertikala prioriteringar ska baseras på de etiska principer som riksdagen beslutat ska gälla vid prioriteringar inom hälso- och sjukvården. De etiska principerna behöver dock göras kända, förtydligas och eventuellt kompletteras för att kunna omsättas i praktiska prioriteringar. Vidare anser vi att riksdagens fyra så kallade prioriteringsgrupper inte ska ingå i modellen.Människovärdesprincipen, som innebär att alla människor bör ha lika värde och samma rätt till vård oberoende av personliga egenskaper och funktioner i samhället, är den självklara utgångspunkten vid prioriteringar. När personliga egenskaper såsom ålder, kön, livsstil eller funktion hos en grupp är ett uttryck för att speciella behov föreligger så att nytta med insatserna blir olika ska de personliga egenskaperna kunna beaktas i en prioritering på gruppnivå. Frågan om hur externa effekter, d v s effekten av en insats för närstående och andra grupper än den individ som är direkt berörd av insatsen, ska värderas vid en prioritering behöver diskuteras ytterligare.Med behov av hälso- och sjukvård menas både tillståndets svårighetsgrad och den förväntade nyttan av en åtgärd. Som patient har man endast behov av sådana vårdåtgärder som man förväntas ha nytta av. Motsatt gäller att en människa enligt detta sätt att definiera behov inte behöver åtgärder som inte förbättrar hälsan och livskvaliteten, sådana som hon inte har nytta av. Här har givetvis hälso- och sjukvården ett ansvar att lotsa människor de kommer i kontakt med, och som far illa på något sätt, till andra lämpliga aktörer.Riksdagens riktlinjer, när det gäller kostnadseffektivitetsprincipen (tillämpad för enskilda patienter), är för begränsad för att vägleda vid vertikala prioriteringar som gäller prioritering på gruppnivå. Regeringen konstaterade redan i prioriteringspropositionen att det är angeläget att skilja på en kostnadseffektivitetsprincip som gäller val mellan olika åtgärder för den enskilde patienten (där principen kan tillämpas som utredningen föreslår) och på hälso- och sjukvårdens strävan efter en hög kostnadseffektivitet när det gäller vårdens verksamhet i allmänhet. Här stödjer vi oss på Riksdagens direktiv till Läkemedelsförmånsnämnden. Nämnden ska vid beslut om subvention (prioriteringar) av ett läkemedel bl a bedöma om det är kostnadseffektivt i ett samhälleligt perspektiv, vilket innebär att man ställer patientnyttan av läkemedlet mot kostnaden. I bedömningen ska kostnadseffektiviteten vägas samman med behovs- och solidaritetsprincipen och människovärdesprincipen.Den föreslagna arbetsmodellen överensstämmer i allt väsentligt med den arbetsmodell som används av Socialstyrelsens vid framtagning av nationella riktlinjer. Det är inte möjligt att rymma alla aspekter som kan vara aktuella att beakta vid beskrivning av en nationell arbetsmodell. Man måste därför utgå från modellen och fundera på vilka andra relevanta aspekter som dessutom bör vägas in. T ex kan den internationella klassifikationen för funktionsförmåga (ICF) användas som vägledning.På grund av den stora variationsrikedomen av effektmått i olika verksamheter och de begränsade erfarenheter som finns att arbeta med sådana explicita gränsvärden anser vi att det är för tidigt att rekommendera en enhetlig indelning i t ex risknivåer. Det är dock viktigt att de som arbetar med prioriteringar redovisar hur de har resonerat.SBU:s klassifikation för att gradera den vetenskapliga evidensen för en åtgärds effekt bör användas i första hand. Lokala prioriteringsprojekt med begränsade resurser till sitt förfogande föreslås redovisa bedömningen av det vetenskapliga underlaget med ord och referera till det kunskapsunderlag som använts. Evidensstyrkan bör endast uttryckas med siffror då man stöder en slutsats på en systematisk kunskapsöversikt från SBU eller en annan översikt av god kvalitet.Prioriteringsarbeten där hälsoekonomiska data finns tillgängliga bör tills vidare ansluta till Socialstyrelsens arbetssätt och ange kostnadseffektivitet i en skala från låg till mycket hög kostnad per vunnet levnadsår eller kostnad per kvalitetsjusterat levnadsår. Den hälsoekonomiska evidensen bör redovisas i enlighet med de principer som Socialstyrelsen tillämpar. I lokala projekt med små resurser eller svårigheter att konsekvent få fram uppgifter om kostnadseffektivitet rekommenderar vi att man åtminstone resonerar om kostnadseffektivitet i de fall prioriteringsordningen på ett avgörande sätt påverkas när kostnaderna vägs in.Tio nivåer bör användas för rangordning samt att rangordningslistan kompletteras med en ”icke-göra-lista” för metoder som inte bör utföras alls eller rutinmässigt samt en FoU-lista för metoder där det fortfarande saknas tillräcklig evidens för att kunna motivera ett införande i rutinsjukvården. Sammanvägningen sker företrädesvis med en kvalitativ metod i avsaknad av en invändningsfri kvantitativ/matematisk metod. Likaså tror vi att det för närvarade inte är möjligt att fastställa entydiga kriterier som avgör inom vilken rangordningsnivå ett prioriteringsobjekt ska hamna.Resultatet bör presenteras i form av en rangordningslista. De parametrar som ligger till grund för prioriteringen bör också på ett enhetligt sätt redovisas i sådana rangordningslistor som visas för andra. I detalj kan språket och utseendet av pedagogiska skäl behöva anpassas för respektive målgrupp.Gränser för vad som är acceptabel behovstäckning (vårdkvalitet, mängd liksom andel av de i patientgrupp som får tillgång till insatsen) är en regional och lokal fråga och ingår därför inte i den nationella modellen.

(author) Vaginal dysbiosis in pregnancy associates with risk of emergency caesarean section: a prospective cohort study 2022 In: Clinical Microbiology and Infection. - Oxford, United Kingdom : Elsevier. - 1198-743X .- 1469-0691. ; 28:4, s. 588-595 Journal article (peer-reviewed)abstract Objectives: To investigate changes in vaginal microbiota during pregnancy, and the association between vaginal dysbiosis and reproductive outcomes.Methods: A total of 730 (week 24) and 666 (week 36) vaginal samples from 738 unselected pregnant women were studied by microscopy (Nugent score) and characterized by 16S rRNA gene sequencing. A novel continuous vaginal dysbiosis score was developed based on these methods using a supervised partial least squares model.Results: Among women with bacterial vaginosis in week 24 (n = 53), 47% (n = 25) also had bacterial vaginosis in week 36. In contrast, among women without bacterial vaginosis in week 24, only 3% (n = 18) developed bacterial vaginosis in week 36. Vaginal samples dominated by Lactobacillus crispatus (OR 0.35, 95% CI 0.20–0.60) and Lactobacillus iners (OR 0.40, 95% CI 0.23–0.68) in week 24 were significantly more stable by week 36 when compared with other vaginal community state types. Vaginal dysbiosis score at week 24 was associated with a significant increased risk of emergency, but not elective, caesarean section (OR 1.37, 955 CI 1.15–1.64, p < 0.001), suggesting a 37% increased risk per standard deviation increase in vaginal dysbiosis score.Conclusions: Changes in vaginal microbiota from week 24 to week 36 of pregnancy correlated with bacterial vaginosis status and vaginal community state type. A novel vaginal dysbiosis score was associated with a significantly increased risk of emergency, but not elective, caesarean section. This was not found for bacterial vaginosis or any vaginal community state type and could point to the importance of investigating vaginal dysbiosis as a nuanced continuum instead of crude clusters.

(author) Fish Oil Supplementation in Pregnancy Increases Gestational Age, Size for Gestational Age, and Birth Weight in Infants: A Randomized Controlled Trial 2019 In: Journal of Nutrition. - : Elsevier BV. - 1541-6100 .- 0022-3166. ; 149:4, s. 628-634 Journal article (peer-reviewed)abstract BACKGROUND: Randomized trials have reported that supplementation with n-3 long-chain polyunsaturated fatty acids (LCPUFAs) in pregnancy can prolong pregnancy and thereby increase birth weight. OBJECTIVE: We aimed to examine the relations of n-3 LCPUFA supplementation in pregnancy with duration of pregnancy, birth weight, and size for gestational age (GA). METHODS: This was a double-blind randomized controlled trial conducted in 736 pregnant women and their offspring, from the Copenhagen Prospective Studies on Asthma in Childhood2010cohort. They were recruited between weeks 22 and 26 in pregnancyand randomly assigned to either of 2.4 g n-3 LCPUFA or control (olive oil) daily until 1 wk after birth. Exclusion criteria were endocrine, cardiovascular, or nephrologic disorders and vitamin D supplementation intake >600 IU/d. In this study we analyzed secondary outcomes, and further excluded twin pregnancies and extrauterine death. The primary outcome for the trial was persistent wheeze or asthma. RESULTS: The random assignment ran between 2008 and 2010. Six hundred and ninety-nine mother-infant pairs were included in the analysis. n-3 LCPUFA compared with control was associated with a 2-d prolongation of pregnancy [median (IQR): 282 (275-288) d compared with 280 (273-286) d, P = 0.02], a 97-g higher birth weight (mean ± SD: 3601 ± 534 g compared with 3504 ± 528 g, P = 0.02), and an increased size for GA according to the Norwegian population-based growth curves-Skjærven (mean ± SD: 49.9 ± 28.3 percentiles compared with 44.5 ± 27.6 percentiles, P = 0.01). CONCLUSION: Supplementing pregnant women with n-3 LCPUFAs during the third trimester is associated with prolonged gestation and increased size for GA, leading to a higher birth weight in this randomized controlled trial. This trial was registered at clinicaltrials.gov as NCT00798226.

(author) Variants in the fetal genome near pro-inflammatory cytokine genes on 2q13 associate with gestational duration. 2019 In: Nature communications. - : Springer Science and Business Media LLC. - 2041-1723. ; 10:1 Journal article (peer-reviewed)abstract The duration of pregnancy is influenced by fetal and maternal genetic and non-genetic factors. Here we report a fetal genome-wide association meta-analysis of gestational duration, and early preterm, preterm, and postterm birth in 84,689 infants. One locus on chromosome 2q13 is associated with gestational duration; the association is replicated in 9,291 additional infants (combined P=3.96×10-14). Analysis of 15,588 mother-child pairs shows that the association is driven by fetal rather than maternal genotype. Functional experiments show that the lead SNP, rs7594852, alters the binding of the HIC1 transcriptional repressor. Genes at the locus include several interleukin 1 family members with roles in pro-inflammatory pathways that are central to the process of parturition. Further understanding of the underlying mechanisms will be of great public health importance, since giving birth either before or after the window of term gestation is associated with increased morbidity and mortality.
10.	Smith, Jennifer A, et al. (author) Genome-wide association study identifies 74 loci associated with educational attainment 2016 In: Nature (London). - : Springer Science and Business Media LLC. - 1476-4687 .- 0028-0836. ; 533:7604, s. 539-542 Journal article (peer-reviewed)abstract Educational attainment is strongly influenced by social and other environmental factors, but genetic factors are estimated to account for at least 20% of the variation across individuals. Here we report the results of a genome-wide association study (GWAS) for educational attainment that extends our earlier discovery sample of 101,069 individuals to 293,723 individuals, and a replication study in an independent sample of 111,349 individuals from the UK Biobank. We identify 74 genome-wide significant loci associated with the number of years of schooling completed. Single-nucleotide polymorphisms associated with educational attainment are disproportionately found in genomic regions regulating gene expression in the fetal brain. Candidate genes are preferentially expressed in neural tissue, especially during the prenatal period, and enriched for biological pathways involved in neural development. Our findings demonstrate that, even for a behavioural phenotype that is mostly environmentally determined, a well-powered GWAS identifies replicable associated genetic variants that suggest biologically relevant pathways. Because educational attainment is measured in large numbers of individuals, it will continue to be useful as a proxy phenotype in efforts to characterize the genetic influences of related phenotypes, including cognition and neuropsychiatric diseases.

(author) A novel common variant in DCST2 is associated with length in early life and height in adulthood. 2015 In: Human molecular genetics. - : Oxford University Press (OUP). - 1460-2083 .- 0964-6906. ; 24:4, s. 1155-68 Journal article (peer-reviewed)abstract Common genetic variants have been identified for adult height, but not much is known about the genetics of skeletal growth in early life. To identify common genetic variants that influence fetal skeletal growth, we meta-analyzed 22 genome-wide association studies (Stage 1; N = 28 459). We identified seven independent top single nucleotide polymorphisms (SNPs) (P < 1 × 10(-6)) for birth length, of which three were novel and four were in or near loci known to be associated with adult height (LCORL, PTCH1, GPR126 and HMGA2). The three novel SNPs were followed-up in nine replication studies (Stage 2; N = 11 995), with rs905938 in DC-STAMP domain containing 2 (DCST2) genome-wide significantly associated with birth length in a joint analysis (Stages 1 + 2; β = 0.046, SE = 0.008, P = 2.46 × 10(-8), explained variance = 0.05%). Rs905938 was also associated with infant length (N = 28 228; P = 5.54 × 10(-4)) and adult height (N = 127 513; P = 1.45 × 10(-5)). DCST2 is a DC-STAMP-like protein family member and DC-STAMP is an osteoclast cell-fusion regulator. Polygenic scores based on 180 SNPs previously associated with human adult stature explained 0.13% of variance in birth length. The same SNPs explained 2.95% of the variance of infant length. Of the 180 known adult height loci, 11 were genome-wide significantly associated with infant length (SF3B4, LCORL, SPAG17, C6orf173, PTCH1, GDF5, ZNFX1, HHIP, ACAN, HLA locus and HMGA2). This study highlights that common variation in DCST2 influences variation in early growth and adult height.

We performed a genome-wide association study meta-analysis of BMI in 61,111 children aged between 2 and 10 years. Twenty-five independent loci reached genome-wide significance in the combined discovery and replication analyses. Two of these, located near NEDD4L and SLC45A3, have not previously been reported in relation to either childhood or adult BMI. Positive genetic correlations of childhood BMI with birth weight and adult BMI, waist-to-hip ratio, diastolic blood pressure and type 2 diabetes were detected (Rg ranging from 0.11 to 0.76, P-values <0.002). A negative genetic correlation of childhood BMI with age at menarche was observed. Our results suggest that the biological processes underlying childhood BMI largely, but not completely, overlap with those underlying adult BMI. The well-known observational associations of BMI in childhood with cardio-metabolic diseases in adulthood may reflect partial genetic overlap, but in light of previous evidence, it is also likely that they are explained through phenotypic continuity of BMI from childhood into adulthood.

(author) Insufficient maternal iodine intake is associated with subfecundity, reduced foetal growth, and adverse pregnancy outcomes in the Norwegian Mother, Father and Child Cohort Study. 2020 In: BMC medicine. - : Springer Science and Business Media LLC. - 1741-7015. ; 18:1 Journal article (peer-reviewed)abstract Severe iodine deficiency impacts fertility and reproductive outcomes. The potential effects of mild-to-moderate iodine deficiency are not well known. The aim of this study was to examine whether iodine intake was associated with subfecundity (i.e. >12months trying to get pregnant), foetal growth, and adverse pregnancy outcomes in a mild-to-moderately iodine-deficient population.We used the Norwegian Mother, Father and Child Cohort Study (MoBa) and included 78,318 pregnancies with data on iodine intake and pregnancy outcomes. Iodine intake was calculated using an extensive food frequency questionnaire in mid-pregnancy. In addition, urinary iodine concentration was available in a subsample of 2795 pregnancies. Associations were modelled continuously by multivariable regression controlling for a range of confounding factors.The median iodine intake from food was 121μg/day and the median urinary iodine was 69μg/L, confirming mild-to-moderate iodine deficiency. In non-users of iodine supplements (n=49,187), low iodine intake (<100-150μg/day) was associated with increased risk of preeclampsia (aOR=1.14 (95% CI 1.08, 1.22) at 75 vs. 100μg/day, p overall <0.001), preterm delivery before gestational week 37 (aOR=1.10 (1.04, 1.16) at 75 vs. 100μg/day, p overall=0.003), and reduced foetal growth (-0.08 SD (-0.10, -0.06) difference in birth weight z-score at 75 vs. 150μg/day, p overall <0.001), but not with early preterm delivery or intrauterine death. In planned pregnancies (n=56,416), having an iodine intake lower than ~100μg/day was associated with increased prevalence of subfecundity (aOR=1.05 (1.01, 1.09) at 75μg/day vs. 100μg/day, p overall=0.005). Long-term iodine supplement use (initiated before pregnancy) was associated with increased foetal growth (+0.05 SD (0.03, 0.07) on birth weight z-score, p<0.001) and reduced risk of preeclampsia (aOR 0.85 (0.74, 0.98), p=0.022), but not with the other adverse pregnancy outcomes. Urinary iodine concentration was not associated with any of the dichotomous outcomes, but positively associated with foetal growth (n=2795, p overall=0.017).This study shows that a low iodine intake was associated with restricted foetal growth and a higher prevalence of preeclampsia in these mild-to-moderately iodine-deficient women. Results also indicated increased risk of subfecundity and preterm delivery. Initiating iodine supplement use in pregnancy may be too late.

(author) Calprotectin levels in amniotic fluid in relation to intra-amniotic inflammation and infection in women with preterm labor with intact membranes: A retrospective cohort study 2022 In: European Journal of Obstetrics & Gynecology and Reproductive Biology. - : Elsevier BV. - 1872-7654 .- 0301-2115. ; 272, s. 24-29 Journal article (peer-reviewed)abstract Objective: To evaluate the concentrations of calprotectin in amniotic fluid with respect to intra-amniotic inflammation and infection and to assess the presence or absence of bacteria in the amnio-chorionic niche with respect to presence or absence of intra-amniotic inflammation. Study design: Seventy-nine women with singleton pregnancies and preterm labor with intact membranes (PTL) were included in the study. Amniotic fluid was collected at the time of admission by amniocentesis and calprotectin levels were analyzed from frozen/thawed samples using ELISA. Interleukin (IL)-6 concentration was measured by point-of-care test. Samples from amniotic fluid and the amnio-chorionic niche (space between amniotic and chorionic membranes) were microbiologically analyzed. Microbial invasion of the amniotic cavity (MIAC) was diagnosed based on a positive PCR result for Ureaplasma species, Mycoplasma hominis, 16S rRNA or positive culture. Intra-amniotic inflammation (IAI) was defined as amniotic fluid point-of-care IL-6 concentration ≥ 745 pg/mL. The cohort of included women was divided into 4 subgroups based on the presence or absence of IAI/MIAC; i) intra-amniotic infection, ii) sterile IAI, iii) intra-amniotic colonization and iv) neither MIAC nor IAI. Results: Women with intra-amniotic infection had a significantly higher intra-amniotic calprotectin concentration (median; 101.6 µg/mL) compared with women with sterile IAI (median; 9.2 µg/mL), women with intra-amniotic colonization (median; 2.6 µg/mL) and women with neither MIAC nor IAI (median 4.6 µg/mL) (p = 0.001). Moreover, significantly higher amniotic fluid calprotectin concentration was seen in women who delivered within 7 days (p = 0.003). A significant negative correlation was found between amniotic fluid calprotectin and gestational age at delivery (rho = 0.32, p = 0.003). Relatively more bacteria in the amnio-chorionic niche were found in the sterile IAI group compared with the other groups. Conclusions: Calprotectin concentrations in amniotic fluid were significantly higher in the intra-amniotic infection group compared with the other groups. Moreover, the bacterial presence in the amnio-chorionic niche was higher in IAI group.

Specifically, the study investigated whether these intra-amniotic inflammatory changes were more common in women with microbial invasion of amniotic cavity (MIAC) and intra-amniotic inflammation (IAI), as indicated by increased amniotic fluid interleukin (IL)-6 concentration (≥3000pg/mL).A cohort of 114 women with singleton pregnancies complicated by PPROM between 24+0 and 36+6 weeks of gestation were included. Amniotic fluid samples were obtained via amniocentesis upon admission. MIAC diagnosis involved aerobic and anaerobic cultures, as well as polymerase chain reaction (PCR) analysis of the amniotic fluid. Immunoassay tests and enzyme-linked immunosorbent assay (ELISA) were used to determine IL-6 and IP-10 concentrations, respectively.Among the participants, 19.3% and 15.8% had MIAC and IAI, respectively. The occurrence of intra-amniotic inflammatory changes associated with chronic inflammation in the placenta was similar between women with and without MIAC (25% vs. 40.9%, p=0.136, adjusted p=0.213). The rate of intra-amniotic inflammatory changes associated with chronic inflammation in the placenta was significantly higher in women with IAI compared to those without, after adjusting for gestational age at sampling (55.6% vs. 22.9%, p=0.005, adjusted p=0.011).This study revealed comparable rates of intra-amniotic inflammatory changes associated with chronic inflammation in the placenta in women with and without MIAC, but a higher prevalence of intra-amniotic inflammatory changes associated with chronic inflammation in the placenta in women with IAI. These findings suggest involvement of chronic inflammation even in women with PPROM with acute intra-amniotic inflammation.

Antecedents of accompanying impairments in cerebral palsy and their relation to neuroimaging patterns need to be explored. Material and methods. A population-based study of 309 children with cerebral palsy born at term between 1983 and 1994. Prepartum, intrapartum, and postpartum variables previously studied as antecedents of cerebral palsy type and motor severity were analyzed in children with cerebral palsy and cognitive impairment and/or epilepsy, and in children with cerebral palsy without these accompanying impairments. Neuroimaging patterns and their relation to identified antecedents were analyzed. Data were retrieved from the cerebral palsy register of western Sweden, and from obstetric and neonatal records. Results. Children with cerebral palsy and accompanying impairments more often had low birthweight (kg) (odds ratio 0.5, 95% confidence interval 0.3-0.8), brain maldevelopment known at birth (p = 0.007, odds ratio infinity) and neonatal infection (odds ratio 5.4, 95% confidence interval 1.04-28.4). Moreover, neuroimaging patterns of maldevelopment (odds ratio 7.2, 95% confidence interval 2.9-17.2), cortical/subcortical lesions (odds ratio 5.3, 95% confidence interval 2.3-12.2) and basal ganglia lesions (odds ratio 7.6, 95% confidence interval 1.4-41.3) were more common, wheras white matter injury was found significantly less often (odds ratio 0.2, 95% confidence interval 0.1-0.5). In most children with maldevelopment, the intrapartum and postpartum periods were uneventful (p

Material and methods. A population-based study in which all 309 term-born children with spastic and dyskinetic cerebral palsy born between 1983 and 1994 and 618 matched controls were studied. Antecedents were retrieved from obstetric records. Information on neuroimaging was retrieved from the cerebral palsy Register of Western Sweden. Cases were grouped by severity of motor impairment: mild (walks without aids), moderate (walks with aids) or severe (dependent on wheelchair). Binary logistic regression, the Cochran-Armitage test for trends, interaction analyses and interrelationship analyses were performed. Results. Antecedents associated with mild motor impairment were antepartum (placental weight, maternal weight and antibiotic therapy) or intrapartum and postpartum adverse events (meconium-stained amniotic fluid, low Apgar score, admission to neonatal intensive care unit and neonatal encephalopathy). Antecedents associated with severe motor impairment were antepartum (congenital infection, small head circumference and brain maldevelopment) or intrapartum and postpartum (emergency cesarean section and maternal antibiotic therapy). Comparisons between mild and severe motor impairment revealed congenital infection, maldevelopment, neonatal encephalopathy and meconium aspiration syndrome significantly more often in the group with severe motor impairment (p

DESIGN: A population-based, case-control study. SETTING: The western healthcare region of Sweden. POPULATION: A population-based series of children with CP born at term during 1983-94 (n=309) was matched with a control group (n=618). METHODS: A total of 62 variables, maternal characteristics, and prepartal, intrapartal and postpartal variables were retrieved from obstetric records. Both univariate and multivariate analyses were performed for spastic and dyskinetic CP, and for the total CP group. MAIN OUTCOME MEASURES: Cerebral palsy (CP) and subtypes. RESULTS: Univariate analysis resulted in 26 significant risk factors for CP. Birthweight (OR0.54, 95%CI0.39-0.74), not living with the baby's father (OR2.58, 95%CI 1.11-5.97), admittance to a neonatal intensive care unit (NICU) (OR 4.43, 95% CI 3.03-6.47), maternal weight at 34weeks of gestation (OR1.02, 95%CI 1.00-1.03) and neonatal encephalopathy (OR69.2, 95%CI 9.36-511.89) were found to be risk factors for CP in the totalCP group in our multivariate analysis. Factors during the periods before, during and after delivery were all shown to increase the risk of spastic diplegia and tetraplegia, whereas mostly factors during the period before delivery increased the risk of spastic hemiplegia, and only factors during delivery increased the risk of dyskinetic CP. Admittance to an NICU was a risk factor for all CP subtypes. CONCLUSIONS: The risk factor pattern differed by CP subtype. The presented risk factors may be useful indicators for identifying children at risk of developing CP, and helpful for targeting individuals for early intervention programmes.

Medical treatment with the adrenotoxic drug mitotane has been used for decades, but critical prospective trials on its role in residual disease or as an adjuvant agent after surgical resection are still lacking. The concept of a critical threshold plasma level of the drug must be confirmed in controlled studies. Because individual responsiveness cannot be predicted, the use mitotane is still advised for nonresectable disease. In case of cortisol or other steroid overproduction, several drugs (e.g., ketoconazole or aminoglutethimide) may be used. Chemotherapy with single agents (e.g., doxorubicin or cisplatin) have been disappointing, with low response rates (< 30%) and a short response duration. Part of this refractoriness may be explained by the fact that ACC tumors express the multidrug-resistance gene MDR-1. Chemotherapy with multiple agents has been tested in smaller series and has resulted in significant side effects. The best results were achieved by the combination of etoposide, doxorubicin, and cisplatin associated with mitotane, achieving a response rate of 54%, including individual complete responses. To be able to make progress in treating advanced ACC disease, adjuvant multicenter trials must be encouraged. When mitotane-based therapies are used, monitored drug levels are mandatory.

Although the development of autism and schizophrenia are linked to infections during fetal life, it is unknown whether more common psychiatric conditions such as depression might begin in utero.To estimate the risk of psychopathologic conditions imparted from fetal exposure to any maternal infection while hospitalized during pregnancy.A total of 1791520 Swedish children born between January 1, 1973, and December 31, 2014, were observed for up to 41 years using linked population-based registries. Children were excluded if they were born too late to contribute person-time, died before being at risk for the outcome, or were missing particular model data. Infection and psychiatric diagnoses were derived using codes from hospitalizations. Directed acyclic graphs were developed from a systematic literature review to determine Cox proportional hazards regression models for risk of psychopathologic conditions in the children. Results were evaluated using probabilistic and simple bias analyses. Statistical analysis was conducted from February 10 to October 17, 2018.Hospitalization during pregnancy with any maternal infection, severe maternal infection, and urinary tract infection.Inpatient diagnosis of autism, depression, bipolar disorder, or psychosis among offspring.A total of 1791520 Swedish-born children (48.6% females and 51.4% males) were observed from birth up to age 41 years, with a total of 32125813 person-years. Within the directed acyclic graph framework of assumptions, fetal exposure to any maternal infection increased the risk of an inpatient diagnosis in the child of autism (hazard ratio [HR], 1.79; 95% CI, 1.34-2.40) or depression (HR, 1.24; 95% CI, 1.08-1.42). Effect estimates for autism and depression were similar following a severe maternal infection (autism: HR, 1.81; 95% CI, 1.18-2.78; depression: HR, 1.24; 95% CI, 0.88-1.73) or urinary tract infection (autism: HR, 1.89; 95% CI, 1.23-2.90; depression: HR, 1.30; 95% CI, 1.04-1.61) and were robust to moderate unknown confounding. Within the directed acyclic graph framework of assumptions, the relationship between infection and depression was vulnerable to bias from loss to follow-up, but separate data from the Swedish Death Registry demonstrated increased risk of suicide among individuals exposed to pregnancy infection. No evidence was found for increased risk of bipolar disorder or psychosis among children exposed to infection in utero.These findings suggest that fetal exposure to a maternal infection while hospitalized increased the risk for autism and depression, but not bipolar or psychosis, during the child's life. These results emphasize the importance of avoiding infections during pregnancy, which may impart subtle fetal brain injuries contributing to development of autism and depression.

Although the classic infectious TORCH pathogens (ie, Toxoplasma gondii, rubella virus, cytomegalovirus [CMV], herpes simplex virus) are known to be directly teratogenic, emerging evidence suggests that these infections represent the most extreme end of a much larger spectrum of injury. We present the accumulating evidence that prenatal exposure to a wide variety of viral and bacterial infections-or simply inflammation-may subtly alter fetal brain development, leading to neuropsychiatric consequences for the child later in life. The link between influenza infections in pregnant women and an increased risk for development of schizophrenia in their children was first described more than 30 years ago. Since then, evidence suggests that a range of infections during pregnancy may also increase risk for autism spectrum disorder and depression in the child. Subsequent studies in animal models demonstrated that both pregnancy infections and inflammation can result in direct injury to neurons and neural progenitor cells or indirect injury through activation of microglia and astrocytes, which can trigger cytokine production and oxidative stress. Infectious exposures can also alter placental serotonin production, which can perturb neurotransmitter signaling in the developing brain. Clinically, detection of these subtle injuries to the fetal brain is difficult. As the neuropsychiatric impact of perinatal infections or inflammation may not be known for decades after birth, our construct for defining teratogenic infections in pregnancy (eg, TORCH) based on congenital anomalies is insufficient to capture the full adverse impact on the child. We discuss the clinical implications of this body of evidence and how we might place greater emphasis on prevention of prenatal infections. For example, increasing uptake of the seasonal influenza vaccine is a key strategy to reduce perinatal infections and the risk for fetal brain injury. An important research gap exists in understanding how antibiotic therapy during pregnancy affects the fetal inflammatory load and how to avoid inflammation-mediated injury to the fetal brain. In summary, we discuss the current evidence and mechanisms linking infections and inflammation with the increased lifelong risk of neuropsychiatric disorders in the child, and how we might improve prenatal care to protect the fetal brain.

Centralized obstetrical care requires competent ambulance staff 2004 In: Lakartidningen. ; 101:41, s. 3148-50 Journal article (peer-reviewed)abstract One hundred and sixty-seven women gave birth before arrival at the hospital during a six-year period in the Goteborg area. Most of these women had given birth before. The actual delivery most often started at term during the night, proceeded normally but rapidly and the neonatal outcome was good. Sixty-two per cent of the women delivered at home. Complicated lacerations or major hemorrhages were uncommon. The distance to the delivery ward was one of the risk factors for prehospital delivery. This is important to take into consideration in the ongoing process of centralizing the delivery clinics. Basic knowledge in obstetrics is mandatory for the ambulance personnel, as well as regular observation visits to the delivery ward and practice in birth simulators.

Our aim was to study whether neonates born SGA have an altered profile of steroid hormones at birth.A total of 168 singletons (99 boys, 69 girls) born at 32.0-36.9 gestational weeks were recruited to a population-based, university hospital, single-center study. Of these, 31 infants (17 boys, 14 girls) were born SGA. The concentrations of dehydroepiandrosterone sulfate (DHEAS), androstenedione, testosterone, dihydrotestosterone, estrone, estradiol, cortisone, and cortisol were analyzed in umbilical cord serum with mass spectrometry.Girls born SGA had higher levels of androstenedione than girls born appropriate for gestational age (AGA) (4.0 versus 2.6nmol/L, p = 0.002). Boys born SGA had lower levels of estrone than boys born AGA (33822 versus 62471pmol/L, p = 0.038). Infants born SGA had lower levels of cortisone than infants born AGA, both in girls (340 versus 579nmol/L, p = 0.010) and in boys (308 versus 521nmol/L, p = 0.045). Furthermore, boys born SGA had a higher cortisol/cortisone ratio than boys born AGA (0.41 versus 0.25, p = 0.028). Gestational age correlated with DHEAS (boys r = 0.48, p = 0.000, girls r = 0.35, p = 0.013), and cortisol (boys r = 0.48, p = 0.000, girls r = 0.29, p = 0.039).In moderate-to-late preterm infants born SGA we observed a different steroid hormone profile in cord serum. Girls born SGA show increased levels of androstenedione and boys born SGA show decreased levels of estrone in cord serum, which could be related to placental aromatase deficiency in intrauterine growth restriction.

Maternal immunization recommendations followed the recognition of the consequences of infectious diseases in pregnancy, including vertical transmission and perinatal consequences. The recent COVID-19 pandemic highlighted the issue of vaccination among pregnant individuals. Recommendations vary globally; however, Tdap, influenza, and, recently, COVID-19 vaccines are routinely recommended during pregnancy. There are several new maternal immunization products in the pipeline, including those directed against malaria, cytomegalovirus, Group B Streptococcus, herpes simplex virus, and respiratory syncytial virus. Important challenges must be addressed in all countries to guarantee that pregnant individuals and their babies receive the best care possible, including uptake of recommended immunizations by their entire target population groups. These challenges include disseminating appropriate data for vaccine recommendations and many others, such as ensuring stakeholder endorsement, achieving in-country distribution and administration, adequate vaccine supply, and a well-organized healthcare system, ideally offering the immunization free of charge. More recently, the hesitancy of pregnant women to receive immunizations highlights the relevance of cultural aspects and other contextual factors affecting vaccine uptake among pregnant individuals.

Cervical and amniotic fluids were obtained at the time of admission, and concentrations of calreticulin and cathepsin-G in cervical fluid were determined using ELISA. The MIAC was defined as a positive PCR analysis for Ureaplasma species, Mycoplasma hominis, and/or Chlamydia trachomatis and/or by positivity for the 16S rRNA gene. IAI was defined as amniotic fluid bedside IL-6 concentrations ≥745pg/mL Result: Neither women with MIAC nor with IAI had different cervical fluid concentrations of calreticulin (with MIAC: median 18.9pg/mL vs. without MIAC: median 14.7pg/mL, p=0.28; with IAI: median 14.3pg/mL vs. without IAI: median 15.6pg/mL, p=0.57;) or of cathepsin-G (with MIAC: median 30.7pg/mL vs. without MIAC: median 24.7pg/mL, p=0.28; with IAI: median 27.3pg/mL vs. without IAI: median 25.1pg/mL, p=0.80) than women without those complications. No associations between amniotic fluid IL-6 concentrations, gestational age at sampling, and cervical fluid calreticulin and cathepsin-G concentrations were found.Cervical fluid calreticulin and cathepsin-G concentrations did not reflect the presence of MIAC or IAI in women with PPROM.

Material and methods The nationwide population-based Swedish Medical Birth Register was used to study the perinatal outcome in nulliparous women with a singleton, term (gestational weeks 37-44), live fetus in cephalic presentation and a planned vaginal delivery from 1992 to 2011. We included 7796 nulliparous women >= 40 years and 264 262 nulliparous women 25-29 years. Prevalence and risk of intrapartum cesarean section, operative vaginal delivery, obstetric anal sphincter injury and a 5-minute Apgar score <7 were calculated for women >= 40 years stratified for spontaneous onset and induction of labor, using women 25-29 years as the reference in both strata. Crude and adjusted odds ratios (aOR) were calculated by unconditional logistic regression and presented with 95% confidence intervals (CI). Results Overall, 79% of women >= 40 years with a trial of labor reached a vaginal delivery. After spontaneous onset, intrapartum cesarean section was performed in 15.4% of women >= 40 years compared with 5.4% of women 25-29 years (aOR 3.07, 95% CI 2.81-3.35). Operative vaginal delivery was performed in 22.3% of women >= 40 years compared with 14.2% of women 25-29 years (aOR 1.71, 95% CI 1.59-1.85). After induction of labor, an intrapartum cesarean section was performed in 37.2% women >= 40 years compared with 20.2% women 25-29 years (aOR 2.51, 95% CI 2.24-2.81). Operative vaginal delivery was performed in 22.6% of women >= 40 years compared with 18.4% women 25-29 years (aOR 1.45, 95% CI 1.28-1.65). The risk of obstetric anal sphincter injury or a 5-minute Apgar score <7 was not increased in women >= 40 years, regardless of onset of labor. Conclusions Trial of labor ended in vaginal delivery in 79% of nulliparous women >= 40 years. The risks of intrapartum cesarean section and operative vaginal delivery were higher in women >= 40 years compared with women 25-29 years, after both spontaneous onset and induction of labor. The risk of obstetric anal sphincter injury or a 5-minute Apgar score <7 was not increased.

Results are presented as the average treatment effect and numbers needed to treat (NNT).OASIS (third- and fourth-degree perineal injury) in nulliparous women delivered with vacuum extraction.Episiotomy was associated with a reduction in OASIS from 15.5% to 11.8%, average treatment effect -3.66% (95% CI -4.31 to -3.01) and NNT 27. Third-degree perineal injuries were reduced from 14.0% to 10.9% (-3.08, 95% CI -3.71 to -2.42) with NNT 32. Fourth-degree perineal injuries were reduced from 1.6% to 1.0 % (-0.58%, 95% CI -0.79 to -0.37) with NNT 172.Lateral or mediolateral episiotomy reduced the prevalence of OASIS in nulliparous women delivered with vacuum extraction, compared to women with no episiotomy.

Joint position statement : Substandard and disrespectful care in labour - because words matter 2024 In: European Journal of Obstetrics, Gynecology, and Reproductive Biology. - : Elsevier. - 0301-2115 .- 1872-7654. ; 296, s. 205-207 Journal article (peer-reviewed)abstract Substandard or disrespectful care during labour should be of serious concern for healthcare professionals, as it can affect one of the most important events in a woman's life. Substandard care refers to the use of interventions that are not considered best -practice, to the inadequate execution of interventions, to situations where bestpractice interventions are withheld from patients, or there is lack of adequate informed consent. Disrespectful care refers to forms of verbal and non-verbal communication that affect patients' dignity, individuality, privacy, intimacy, or personal beliefs. There are many possible underlying causes for substandard and disrespectful care in labour, including difficulties in modifying behaviours, judgmental or paternalistic attitudes, personal interests and individualism, and a human tendency to make less arduous, less difficult, or less stressful clinical decisions. The term "obstetric violence" is used in some parts of the world to describe various forms of substandard and disrespectful care in labour, but suggests that it is mainly carried out by obstetricians and is a serious form of aggression, carried out with the intent to cause harm. We believe that this term should not be used, as it does not help to identify the underlying problem, its causes, or its correction. In addition, it is generally seen by obstetricians and other healthcare professionals as an unjust and offensive term, generating a defensive and less collaborative mindset. We reach out to all individuals and institutions sharing the common goal of improving women's experience during labour, to work together to address the underlying causes of substandard and disrespectful care, and to develop common strategies to deal with this problem, based on mutual comprehension, trust and respect

(author) EUROPEAN ASSOCIATION OF PERINATAL MEDICINE (EAPM) EUROPEAN MIDWIVES ASSOCIATION (EMA). 2024 In: European journal of obstetrics, gynecology, and reproductive biology. - 1872-7654. ; 294, s. 76-78 Journal article (peer-reviewed)abstract While cesarean deliveries performed for health indications can save lives, unnecessary cesareans cause unjustifiable health risks for the mother, newborn, and for future pregnancies. Previous recommendations for cesarean delivery rates at a country level in the 10-15% range are currently unrealistic, and the proposed concept that striving to achieve specific rates is not important has resulted in a confusing message reaching healthcare professionals and the public. It is important to have a clear understanding of when cesarean delivery rates are deviating from internationally acceptable ranges, to trigger the implementation of healthcare policies needed to correct this problem. Based on currently existing scientific evidence, we recommend that cesarean delivery rates at a country level should be in the 15-20% range. This advice is based on the demonstration of decreased maternal and neonatal mortalities when national cesarean delivery rates rise to circa 15%, but values exceeding 20% are not associated with further benefits. It is also based on real-world experiences from northern European countries, where cesarean delivery rates in the 15-20% range are associated with some of the best maternal and perinatal quality indicators in the world. With the increase in cesarean delivery rates projected for the coming years, experience in provision of intrapartum care may come under threat in many hospitals, and recovering from this situation is likely to be a major challenge. Professional and scientific societies, together with healthcare authorities and governments need to prioritize actions to reverse the upward trend in cesarean delivery rates observed in many countries, and to strive to achieve values as close as possible to the recommended range.
36.	Bacelis, Jonas, 1984, et al. (author) Literature-Informed Analysis of a Genome-Wide Association Study of Gestational Age in Norwegian Women and Children Suggests Involvement of Inflammatory Pathways 2016 In: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 11:8 Journal article (peer-reviewed)abstract Background Five-to-eighteen percent of pregnancies worldwide end in preterm birth, which is the major cause of neonatal death and morbidity. Approximately 30% of the variation in gestational age at birth can be attributed to genetic factors. Genome-wide association studies (GWAS) have not shown robust evidence of association with genomic loci yet. We separately investigated 1921 Norwegian mothers and 1199 children from pregnancies with spontaneous onset of delivery. Individuals were further divided based on the onset of delivery: initiated by labor or prelabor rupture of membranes. Genetic association with ultrasound- dated gestational age was evaluated using three genetic models and adaptive permutations. The top-ranked loci were tested for enrichment in 12 candidate gene-sets generated by text-mining PubMed abstracts containing pregnancy-related keywords. The six GWAS did not reveal significant associations, with the most extreme empirical p = 5.1 x 10(-7). The top loci from maternal GWAS with deliveries initiated by labor showed significant enrichment in 10 PubMed gene-sets, e.g., p = 0.001 and 0.005 for keywords "uterus" and "preterm" respectively. Enrichment signals were mainly caused by infection/inflammation-related genes TLR4, NFKB1, ABCA1, MMP9. Literature-informed analysis of top loci revealed further immunity genes: IL1A, IL1B, CAMP, TREM1, TFRC, NFKBIA, MEFV, IRF8, WNT5A. Our analyses support the role of inflammatory pathways in determining pregnancy duration and provide a list of 32 candidate genes for a follow-up work. We observed that the top regions from GWAS in mothers with labor-initiated deliveries significantly more often overlap with pregnancy-related genes than would be expected by chance, suggesting that increased sample size would benefit similar studies.

(author) Uterine distention as a factor in birth timing: retrospective nationwide cohort study in Sweden. 2018 In: BMJ open. - : BMJ. - 2044-6055. ; 8:10 Journal article (peer-reviewed)abstract To determine whether uterine distention is associated with human pregnancy duration in a non-invasive observational setting.Retrospective cohort study modelling uterine distention by interaction between maternal height and uterine load.The study is based on the 1990-2013 population data from all delivery units in Sweden.Uncomplicated first pregnancies of healthy Nordic-born mothers with spontaneous onset of labour. Pregnancies were classified as twin (n=2846) or singleton (n=527868). Singleton pregnancies were further classified as carrying a large for gestational age fetus (LGA, n=24286) or small for gestational age fetus (SGA, n=33780).Statistical interaction between maternal height and uterine load categories (twin vs singleton pregnancies, and LGA vs SGA singleton pregnancies), where the outcome is pregnancy duration.In all models, statistically significant interaction was found. Mothers carrying twins had 2.9 times larger positive linear effect of maternal height on gestational age than mothers carrying singletons (interaction p=5e-14). Similarly, the effect of maternal height was strongly modulated by the fetal growth rate in singleton pregnancies: the effect size of maternal height on gestational age in LGA pregnancies was 2.1 times larger than that in SGA pregnancies (interaction p<1e-11). Preterm birth OR was 1.4 when the mother was short, and 2.8 when the fetus was extremely large for its gestational age; however, when both risk factors were present together, the OR for preterm birth was larger than expected, 10.2 (interaction p<0.0005).Across all classes, maternal height was significantly associated with child's gestational age at birth. Interestingly, in short-statured women with large uterine load (twins, LGA), spontaneous delivery occurred much earlier than expected. The interaction between maternal height, uterine load size and gestational age at birth strongly suggests the effect of uterine distention imposed by fetal growth on birth timing.
38.	Barman, Malin, 1983, et al. (author) Maternal dietary selenium intake is associated with increased gestational length and decreased risk of preterm delivery 2020 In: British Journal of Nutrition. - 0007-1145 .- 1475-2662. ; 123:2, s. 209-219 Journal article (peer-reviewed)abstract The first positive genome-wide association study on gestational length and preterm delivery showed associations with a gene involved in the selenium metabolism. In this study we examine the associations between maternal intake of selenium and selenium status with gestational length and preterm delivery in 72,025 women with singleton live births from the population based, prospective Norwegian Mother, Father and Child Cohort Study (MoBa). A self-reported, semi-quantitativ food-frequency questionnaire answered in pregnancy week 22 was used to estimate selenium intake during the first half of pregnancy. Associations were analysed with adjusted linear and cox regressions. Selenium status was assessed in whole blood collected in gestational week 17 (n=2,637). Median dietary selenium intake was 53 (IQR: 44-62) μg/day, supplements provided additionally 50 (30-75) μg/day for supplement-users (n=23,409). Maternal dietary selenium intake was significantly associated with prolonged gestational length (β per SD=0.25, 95% CI=0.07-0.43) and decreased risk for preterm delivery (n=3,618, HR per SD=0.92, 95% CI=0.87-0.98). Neither selenium intake from supplements nor maternal blood selenium status was associated with gestational length or preterm delivery. Hence, this study showed that maternal dietary selenium intake, but not intake of selenium containing supplements, during the first half of pregnancy was significantly associated with decreased risk for preterm delivery. Further investigations, preferably in the form of a large RCT, are needed to elucidate the impact of selenium on pregnancy duration.

INTRODUCTION: Prenatal and neonatal environmental factors, such as nutrition, microbes and toxicants, may affect health throughout life. Many diseases, such as allergy and impaired child development, may be programmed already in utero or during early infancy. Birth cohorts are important tools to study associations between early life exposure and disease risk. Here, we describe the study protocol of the prospective birth cohort, 'Nutritional impact on Immunological maturation during Childhood in relation to the Environment' (NICE). The primary aim of the NICE cohort is to clarify the effect of key environmental exposures-diet, microbes and environmental toxicants-during pregnancy and early childhood, on the maturation of the infant's immune system, including initiation of sensitisation and allergy as well as some secondary outcomes: infant growth, obesity, neurological development and oral health.METHODS AND ANALYSIS: The NICE cohort will recruit about 650 families during mid-pregnancy. The principal inclusion criterion will be planned birth at the Sunderby Hospital in the north of Sweden, during 2015-2018. Questionnaires data and biological samples will be collected at 10 time-points, from pregnancy until the children reach 4 years of age. Samples will be collected primarily from mothers and children, and from fathers. Biological samples include blood, urine, placenta, breast milk, meconium, faeces, saliva and hair. Information regarding allergic heredity, diet, socioeconomic status, lifestyle including smoking, siblings, pet ownership, etc will be collected using questionnaires. Sensitisation to common allergens will be assessed by skin prick testing and allergic disease will be diagnosed by a paediatrician at 1 and 4 years of age. At 4 years of age, the children will also be examined regarding growth, neurobehavioural and neurophysiological status and oral health.ETHICS AND DISSEMINATION: The NICE cohort has been approved by the Regional Ethical Review Board in Umeå, Sweden (2013/18-31M). Results will be disseminated through peer-reviewed journals and communicated on scientific conferences.

(author) Genome-wide association study of offspring birth weight in 86,577 women identifies five novel loci and highlights maternal genetic effects that are independent of fetal genetics. 2018 In: Human molecular genetics. - : Oxford University Press (OUP). - 1460-2083 .- 1460-2083 .- 0964-6906. ; 27:4, s. 742-756 Journal article (peer-reviewed)abstract Genome-wide association studies (GWAS) of birth weight have focused on fetal genetics, while relatively little is known about the role of maternal genetic variation. We aimed to identify maternal genetic variants associated with birth weight that could highlight potentially relevant maternal determinants of fetal growth. We meta-analysed data on up to 8.7 million SNPs in up to 86,577 women of European descent from the Early Growth Genetics (EGG) Consortium and the UK Biobank. We used structural equation modelling (SEM) and analyses of mother-child pairs to quantify the separate maternal and fetal genetic effects. Maternal SNPs at 10 loci (MTNR1B, HMGA2, SH2B3, KCNAB1, L3MBTL3, GCK, EBF1, TCF7L2, ACTL9, CYP3A7) were associated with offspring birth weight at P<5x10-8. In SEM analyses, at least 7 of the 10 associations were consistent with effects of the maternal genotype acting via the intrauterine environment, rather than via effects of shared alleles with the fetus. Variants, or correlated proxies, at many of the loci had been previously associated with adult traits, including fasting glucose (MTNR1B, GCK and TCF7L2) and sex hormone levels (CYP3A7), and one (EBF1) with gestational duration. The identified associations indicate genetic effects on maternal glucose, cytochrome P450 activity and gestational duration, and potentially on maternal blood pressure and immune function, are relevant for fetal growth. Further characterization of these associations in mechanistic and causal analyses will enhance understanding of the potentially modifiable maternal determinants of fetal growth, with the goal of reducing the morbidity and mortality associated with low and high birth weights.

Using placental weight as a proxy for placental growth, we report genome-wide association analyses in the fetal (n=65,405), maternal (n=61,228) and paternal (n=52,392) genomes, yielding 40 independent association signals. Twenty-six signals are classified as fetal, four maternal and three fetal and maternal. A maternal parent-of-origin effect is seen near KCNQ1. Genetic correlation and colocalization analyses reveal overlap with birth weight genetics, but 12 loci are classified as predominantly or only affecting placental weight, with connections to placental development and morphology, and transport of antibodies and amino acids. Mendelian randomization analyses indicate that fetal genetically mediated higher placental weight is causally associated with preeclampsia risk and shorter gestational duration. Moreover, these analyses support the role of fetal insulin in regulating placental weight, providing a key link between fetal and placental growth.

(author) FIGO Preconception Checklist: Preconception care for mother and baby. 2024 In: International journal of gynaecology and obstetrics: the official organ of the International Federation of Gynaecology and Obstetrics. - 1879-3479. Journal article (peer-reviewed)abstract The preconception period is a unique and opportunistic time in a woman's life when she is motivated to adopt healthy behaviors that will benefit her and her child, making this time period a critical "window of opportunity" to improve short- and long-term health. Improving preconception health can ultimately improve both fetal and maternal outcomes. Promoting health before conception has several beneficial effects, including an increase in seeking antenatal care and a reduction in neonatal mortality. Preconception health is a broad concept that encompasses the management of chronic diseases, including optimal nutrition, adequate consumption of folic acid, control of body weight, adoption of healthy lifestyles, and receipt of appropriate vaccinations. Use of the FIGO Preconception Checklist, which includes the key elements of optimal preconception care, will empower women and their healthcare providers to better prepare women and their families for pregnancy.

Conference paper (peer-reviewed)abstract Various researchers and policy analysts have experimented with empirical studies of sectoral innovation systems (SIS), in which attempts have been made to understand the current structure of various innovation systems and trace their dynamics. We have captured the dynamics in terms of not only the structural components of a SIS but also pioneered such an analysis in terms of functional patterns (as well as functionality). In a collaborative work with VINNOVA (the Swedish Agency for Innovation Systems), we have taken the analysis one step further and made explicit a scheme of analysis, or a manual for policy makers. The manual is based on the received literature, our prior experience in developing and applying functional thinking and three experimental case studies, conducted in collaboration with VINNOVA. The manual can be used by policy makers to identify not only the key policy issues but also to set policy goals and to assess the usefulness of various policy instruments.

The current study aimed to study whether caffeine intake during pregnancy was associated with impaired child neurodevelopment up to 8years of age.A total of 64,189 full term pregnancies from the Norwegian Mother, Father and Child Cohort Study were included. A validated food-frequency questionnaire administered at gestational week 22 was used to obtain information on maternal caffeine intake from different sources. To assess child neurodevelopment (behaviour, temperament, motor development, language difficulties) validated scales were used to identify difficulties within each domain at 6, 18, 36months as well as 5 and 8years of age. Adjusted logistic regression models and mixed linear models were used to evaluate neurodevelopmental problems associated with maternal caffeine intake.Prenatal caffeine exposure was not associated with a persistently increased risk for behaviour, temperament, motor or language problems in children born at full-term. Results were consistent throughout all follow-ups and for different sources of caffeine intake. There was a minor trend towards an association between consumption of caffeinated soft drinks and high activity level, but this association was not driven by caffeine.Low to moderate caffeine consumption during pregnancy was not associated with any persistent adverse effects concerning the child's neurodevelopment up to 8years of age. However, a few previous studies indicate an association between high caffeine consumption and negative neurodevelopment outcomes.

(author) Study for Improving Maternal Pregnancy And Child ouTcomes (IMPACT): a study protocol for a Swedish prospective multicentre cohort study 2020 In: BMJ Open. - : BMJ. - 2044-6055 .- 2044-6055. ; 10:9, s. e033851-e033851 Journal article (peer-reviewed)abstract Introduction First-trimester pregnancy risk evaluation facilitates individualised antenatal care, as well as application of preventive strategies for pre-eclampsia or birth of a small for gestational age infant. A range of early intervention strategies in pregnancies identified as high risk at the end of the first trimester has been shown to decrease the risk of preterm pre-eclampsia (<37 gestational weeks). The aim of this project is to create the Improving Maternal Pregnancy And Child ouTcomes (IMPACT) database; a nationwide database with individual patient data, including predictors recorded at the end of the first trimester and later pregnancy outcomes, to identify women at high risk of pre-eclampsia. A second aim is to link the IMPACT database to a biobank with first-trimester blood samples. Methods and analysis This is a Swedish prospective multicentre cohort study. Women are included between the 11th and 14th weeks of pregnancy. At inclusion, pre-identified predictors are retrieved by interviews and medical examinations. Blood samples are collected and stored in a biobank. Additional predictors and pregnancy outcomes are retrieved from the Swedish Pregnancy Register. Inclusion in the study began in November 2018 with a targeted sample size of 45 000 pregnancies by end of 2021. Creation of a new risk prediction model will then be developed, validated and implemented. The database and biobank will enable future research on prediction of various pregnancy-related complications. Ethics and dissemination Confidentiality aspects such as data encryption and storage comply with the General Data Protection Regulation and with ethical committee requirements. This study has been granted national ethical approval by the Swedish Ethical Review Authority (Uppsala 2018-231) and national biobank approval at Uppsala Biobank (18237 2 2018 231). Results from the current as well as future studies using information from the IMPACT database will be published in peer-reviewed journals.

Ltd.. ; 13:3, s. 235-240 Journal article (peer-reviewed)abstract This paper identifies and analyses the effects of picture archiving and communica- tion systems (PACS) on radiographers’ work practice. It shows that the introduction of PACS did not simply entail the transfer of data and information from the analogue world to the digital world, but it also led to the introduction of new ways of communicating, and new activities and responsibilities on the part of radiography staff. Radiographers are called upon to work increasingly independently, and individual practitioners require higher levels of professional expertise. In all, this paper demonstrates that new technical solutions sometimes lead to sub- stantial changes in responsibilities in work. In this example, the radiographers’ work practice has become more highly scientific and they are enjoying a higher level of prestige.

Increasing antibiotic resistance has severely limited treatment options. A mechanism that Neisseria gonorrhoeae uses to evade complement attack is binding of the complement inhibitor C4b-binding protein (C4BP). We screened 107 porin B1a (PorB1a) and 83 PorB1b clinical isolates randomly selected from a Swedish strain collection over the last 10 years and noted that 96/107 (89.7%) PorB1a and 16/83 (19.3%) PorB1b bound C4BP; C4BP binding substantially correlated with the ability to evade complement-dependent killing (r = 0.78). We designed 2 chimeric proteins that fused C4BP domains to the backbone of IgG or IgM (C4BP-IgG; C4BP-IgM) with the aim of enhancing complement activation and killing of gonococci. Both proteins bound gonococci (KD C4BP-IgM = 2.4 nM; KD C4BP-IgG 980.7 nM), but only hexameric C4BP-IgM efficiently outcompeted heptameric C4BP from the bacterial surface, resulting in enhanced complement deposition and bacterial killing. Furthermore, C4BP-IgM substantially attenuated the duration and burden of colonization of 2 C4BP-binding gonococcal isolates but not a non-C4BP-binding strain in a mouse vaginal colonization model using human factor H/C4BP-transgenic mice. Our preclinical data present C4BP-IgM as an adjunct to conventional antimicrobials for the treatment of gonorrhea.

In term-born babies, it also seems to improve both the short- and long-term outcomes and shows favorable scores in fine motor and social domains. However, there is insufficient evidence to show what duration of delay is best. The current evidence supports not clamping the cord before 30seconds for preterm births. Future trials could compare different lengths of delay. Until then, a period of 30seconds to 3minutes seems justified for term-born babies.
