Tidskriftsartikel (refereegranskat)abstract
- From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions.

Tidskriftsartikel (refereegranskat)abstract
- Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.

- Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified.

A century of trends in adult human height
- 2016
-
Ingår i: eLIFE. - 2050-084X. ; 5
-
Tidskriftsartikel (refereegranskat)abstract
- Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.522.7) and 16.5 cm (13.319.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries.

Cost-Effectiveness of School-Based Prevention of Cannabis Use
- 2015
-
Ingår i: Applied Health Economics and Health Policy. - : Springer Science and Business Media LLC. - 1175-5652 .- 1179-1896. ; 13

Tidskriftsartikel (refereegranskat)abstract
- Background: Cannabis is the most frequently used illicit drug globally. Despite increasing evidence that cannabis use is associated with adverse health effects, the knowledge on preventative strategies is still limited. This study stemmed from a systematic review of effective prevention in which school-based programmes were identified as promising. The primary objective was to evaluate the cost effectiveness of Project ALERT (Adolescent, Learning, Experiences, Resistance, and Training), compared with ordinary ATOD (Alcohol, Tobacco, and Other Drug) education, among Swedish students in the eighth grade of compulsory school.Methods: The cost-effectiveness analysis was performed from the societal perspective with quality-adjusted lifeyears (QALYs) as an outcome (willingness-to-pay threshold €50,000) and follow-up periods from 1 year to a lifetime, considering a discounting rate of 3 %, and with costs inflated to 2013 levels. A Markov model was constructed on the basis of the ‘states’ of single use, regular use, daily use and use of other illicit drugs, which were associated with ‘complications’ of psychosis, schizophrenia, traffic accidents, depression and amotivational syndrome. Health and cost consequences were linked to both states and complications.Results: The programme was cost saving on the basis of evidence from the USA (ratio 1:1.1), and was cost effective (incremental cost-effectiveness ratio €22,384 per QALY) after reasonable adjustment for the Swedish context and with 20 years of follow-up. When the target group was restricted to boys who were neither studying nor working/doing work experience, the programme was cost effective after 9 years and cost saving (ratio 1:3.2) after 20 years.Conclusion: School-based prevention such as Project ALERT has the potential to be cost effective and to be cost saving if implemented in deprived areas. In the light of the shifting landscape regarding legalization of cannabis, it seems rational to continue the health economic analysis of prevention initiated here.

- Purpose This study seeks to investigate the long-term public health burden of Hodgkin lymphoma (HL) in terms of work loss following contemporary treatment protocols and associations with established treatment complications and lymphoma relapse. Methods We identified 1,989 Swedish HL patients (1,082 with clinical information) aged 18-60 (median 33) years at diagnosis 1992-2009, and matched 1:4 to population comparators. Sick leave, disability pension (work loss), and comorbidity were retrieved through September 2013. Relative risks (RR) with 95 % confidence intervals (CI) were calculated using Poisson regression, and mean lost work days were estimated yearly during follow-up. Results The risk of annual work loss was elevated in HL survivors versus comparators up to the 15th year post-diagnosis (RR5th year 1.64, 95 % CI 1.46-1.84; RR10th year 1.33, 95 % CI 1.15-1.34; and RR15th year 1.30, 95 % CI 1.04-1.62). The risk remained elevated up to the 10th year after adjustment for secondary malignancies and cardiovascular disease (RR10th year 1.31, 95 % CI 1.13-1.52). Advanced-stage patients had more lost days than comparators (mean number(5th year) 66 versus 33, mean difference 34, 95 % CI 20-48) as did patients receiving 6-8 chemotherapy courses (62 versus 33, mean difference(5th year) 30, 95 % CI 17-43). Among patients in the first complete remission, a difference was still observed for advanced-stage (51 versus 33, mean difference(5th year) 19, 95 % CI 5-34) but not early-stage disease. Conclusions Advanced-stage HL survivors treated with full-dose chemotherapy were at increased risk of work loss, not only explained by relapse, secondary malignancies, or cardiovascular disease.

BEST: Bypass equipoise sleeve trial; rationale and design of a randomized, registry-based, multicenter trial comparing Roux-en-Y gastric bypass with sleeve gastrectomy
- 2019
-
Ingår i: Contemporary Clinical Trials. - : Elsevier BV. - 1551-7144 .- 1559-2030. ; 84

Tidskriftsartikel (refereegranskat)abstract
- Background: Laparoscopic gastric bypass (LGBP) is a well-documented surgical intervention for severe obesity. Recently, laparoscopic sleeve gastrectomy (LSG) has gained increased popularity. Short-term follow-up in limited-sized randomized trials comparing LGBP and LSG show no major differences in weight-loss, adverse events, or effect on comorbidities; however, there is a lack of sufficiently powered, pragmatic, randomized controlled trials comparing the mid- and long-term results of the two methods. Method: BEST is a randomized, registry-based, multicenter trial comparing LGBP and LSG. The trial has two primary outcomes; rates of substantial complications (SC) and total body weight loss. We hypothesize that patients treated with LSG will experience 35% fewer substantial complications during the 5-year follow-up compared to patients treated with LGBP, and that the efficacy of LSG will remain within a non-inferiority margin of 5% in terms of weight loss. Our sample size calculation, using data from the Scandinavian Obesity Surgery Registry (SOReg), shows a power of 80% for SC and > 95% for weight loss at p < .025 with a total of 2100 included patients. The design of the trial will also enable comparisons within several relevant patient subgroups. Conclusions: As a large-sized, pragmatic, randomized trial, BEST will provide robust data comparing LGBP with LSG by generating long-term results on weight loss and SC's, as well as secondary outcomes and comparisons within patient subgroups. The use of a well-established registry for registration of all data facilitates a large multicenter trial, and combines the strengths of registry studies with those of a randomized trial.

Prevalence of paediatric inflammatory bowel disease in Sweden : a nationwide population-based register study
- 2017
-
Ingår i: BMC Gastroenterology. - London, England : BioMed Central. - 1471-230X. ; 17
-
Tidskriftsartikel (refereegranskat)abstract
- Background: We evaluated the impact of different case definition algorithms on the prevalence of paediatric inflammatory bowel disease (IBD), Crohn's disease (CD) and ulcerative colitis (UC) and to compare the occurrence of certain diseases compared to matched controls.Methods: Paediatric patients (<18 years) were identified via ICD codes for UC and CD in Swedish registers between 1993 and 2010 (n = 1432). Prevalence was defined as >= 2 IBD-related visits. Prevalence of treated children in 2010 was defined as >= 2 IBD-related visits with one visit and >= 1 dispensed IBD-related drug prescription in 2010. To test the robustness of the estimates, prevalence was also calculated according to alternative case definitions. The presence of rheumatic, hepatobiliary, pancreatic, and dermatologic diseases were compared with age-/sex-/county-of-residence- matched general population controls.Results: The IBD prevalence was 75/100,000 (CD: 29/100,000; UC: 30/100,000; patients with IBD-U: 16/100,000). Prevalence of treated disease in 2010 was 62/100,000 (CD: 23/100,000; UC: 25/100,000; patients with IBD-U: 13/100,000). When age restrictions were employed, the prevalence estimate decreased (<17y: 61/100,000, <16y: 49/100,000 and <15y: 38/100,000).Compared to general population controls (n = 8583), children with IBD had a higher prevalence of dermatologic (4.7% vs. 0.6%), hepatobiliary (including primary sclerosing cholangitis) (5.5% vs. 0.1%), pancreatic (1.7% vs. 0%) and rheumatic diseases (7.2% vs. 1.2%; all P < 0.01).Conclusions: The overall prevalence of paediatric IBD in Sweden was similar to that in earlier regional cohorts. IBD patients had a higher prevalence of comorbid conditions than matched general population controls.

- Objective: To investigate in-depth speech results in the Scandcleft Trial 2 with comparisons between surgical protocols and centers and with benchmarks from peers without cleft palate. Design: A prospective randomized clinical trial. Setting: Two Swedish and one Finnish Cleft Palate center. Participants: One hundred twelve participants were 5-years-old born with unilateral cleft lip and palate randomized to either lip repair and soft palate closure at 4 months and hard palate closure at 12 months or lip repair at 3 to 4 months (Arm A), or a closure of both the soft and hard palate at 12 months (Arm C). Main Outcome Measures: A composite measure dichotomized into velopharyngeal competency (VPC) or velopharyngeal incompetency (VPI), overall assessment of velopharyngeal function (VPC-Rate), percentage of consonants correct (PCC score), and consonant errors. In addition, number of speech therapy visits, average hearing thresholds, and secondary surgeries were documented to assess burden of treatment. Results: Across the trial, 53.5% demonstrated VPC and 46.5% VPI with no significant differences between arms or centers. In total, 27% reached age-appropriate PCC scores with no statistically significant difference between the arms. The Finnish center had significantly higher PCC scores, the Swedish centers had higher percentages of oral consonant errors. Number of speech therapy visits was significantly higher in the Finnish center. Conclusion: At age 5, poor speech outcomes with some differences between participating centers were seen but could not be attributed to surgical protocol. As one center had very few participants, the results from that center should be interpreted with caution. © 2019, American Cleft Palate-Craniofacial Association.

- Patients with cleft lip and palate (CLP) and maxillary retrognathia are usually treated with maxillary advancement (Le Fort I osteotomy). The aim of this study was to investigate the impact of maxillary advancement on the velopharyngeal function (VPF) and symptoms of velopharyngeal incompetence in patients with CLP. Design Retrospective group study before and after treatment. Participants All patients who had undergone Le Fort I osteotomy due to maxillary retrognathia from 2007 to 2010 at Karolinska University Hospital, Sweden (n = 13). Pre- and postoperatively standardized examinations were used. Blinded audio recordings were independently assessed by three experienced speech pathologists. Acoustical data (nasometry) and information on VPF (videoradiography and nasoendoscopy) were collected from the medical records. Two patients with additional malformations were considered outliers, and group data were based on a sample size of n = 11. Main Outcome Measures Perceptual and acoustic symptoms of velopharyngeal incompetence and overall assessment of VPF. Results No assessment method showed a significant deterioration of the VPF postoperatively. Individual data revealed that 6 of the 13 patients had no or only one symptom pre- and/or postoperatively. The two patients with additional malformations had most symptoms pre- and postoperatively and did not change. Three patients had an increased number of symptoms postoperatively by at least two symptoms. No associations between the outcome and possible prognostic factors were found. Conclusions Maxillary advancement did not have a significant impact on the VPF at the group level, but three individuals had a somewhat deteriorated VPF postoperatively.

- A sound localization aid based on eyeglasses with three microphones and four vibrators was tested in a sound-treated acoustic test room and in an ordinary office. A digital signal-processing algorithm provided a determination of the source angle, which was transformed into eight vibrator codes each corresponding to a 45 degrees sector. The instrument was tested on nine deaf and three deaf-blind individuals. The results show an average hit rate of about 80% in a sound-treated room with 100% for the front 135 degrees sector. The results in a realistic communication situation in an ordinary office room were 70% correct based on single presentations and 95% correct when more realistic criteria for an adequate reaction were used. Ten of the twelve subjects were interested in participating in field tests using a planned miniaturized version.

Tidskriftsartikel (refereegranskat)abstract
- IMPORTANCE: Bariatric surgery is a life-changing treatment for patients with severe obesity, but little is known about its association with interpersonal relationships.OBJECTIVES: To investigate if relationship status is altered after bariatric surgery.DESIGN, SETTING, AND PARTICIPANTS: Changes in relationship status after bariatric surgery were examined in 2 cohorts: (1) the prospective Swedish Obese Subjects (SOS) study, which recruited patients undergoing bariatric surgery from September 1, 1987, to January 31, 2001, and compared their care with usual nonsurgical care in matched obese control participants; and (2) participants from the Scandinavian Obesity Surgery Registry (SOReg), a prospective, electronically captured register that recruited patients from January 2007 through December 2012 and selected comparator participants from the general population matched on age, sex, and place of residence. Data was collected in surgical departments and primary health care centers in Sweden. The current analysis includes data collected up until July 2015 (SOS) and December 2012 (SOReg). Data analysis was completed from June 2016 to December 2017.MAIN OUTCOMES AND MEASURES: In the SOS study, information on relationship status was obtained from questionnaires. In the SOReg and general population cohort, information on marriage and divorce was obtained from the Swedish Total Population Registry.RESULTS: The SOS study included 1958 patients who had bariatric surgery (of whom 1389 [70.9%] were female) and 1912 matched obese controls (of whom 1354 [70.8%] were female) and had a median (range) follow-up of 10 (0.5-20) years. The SOReg cohort included 29 234 patients who had gastric bypass surgery (of whom 22 131 [75.6%] were female) and 283 748 comparators from the general population (of whom 214 342 [75.5%] were female), and had a median (range) follow-up of 2.9 (0.003-7.0) years. In the SOS study, the surgical patients received gastric banding (n = 368; 18.8%), vertical banded gastroplasty (n = 1331; 68.0%), or gastric bypass (n = 259; 13.2%); controls received usual obesity care. In SOReg, all 29 234 surgical participants received gastric bypass surgery. In the SOS study, bariatric surgery was associated with increased incidence of divorce/separation compared with controls for those in a relationship (adjusted hazard ratio [aHR] = 1.28; 95% CI, 1.03-1.60; P =.03) and increased incidence of marriage or new relationship (aHR = 2.03; 95% CI, 1.52-2.71; P <.001) in those who were unmarried or single at baseline. In the SOReg and general population cohort, gastric bypass was associated with increased incidence of divorce compared with married control participants (aHR = 1.41; 95% CI, 1.33-1.49; P <.001) and increased incidence of marriage in those who were unmarried at baseline (aHR = 1.35; 95% CI, 1.28-1.42; P <.001). Within the surgery groups, changes in relationship status were more common in those with larger weight loss.CONCLUSIONS AND RELEVANCE: In addition to its association with obesity comorbidities, bariatric surgery-induced weight loss is also associated with changes in relationship status.

- Although there is no doubt about the scientific value of randomized controlled clinical trials, they are usually conducted in selected populations different fromthose treated in clinical practice. Therefore, it is important to optimize real-time post-marketing evaluation of the effectiveness, safety, and cost of new drugs. Using electronic health records and administrative health databases froma well-defined region with universal access to healthcare, we have built a framework for real-time sequential monitoring of the effectiveness of newly marketed drugs in routine care. We chose the antiarrhythmic agent dronedarone as the study drug and flecainide as the comparator drug for illustration of the model. We demonstrate that this model produces consistent results with increasing precision over time as data accumulates in the clinical systems. We believe that use of this model at the introduction of new drugs can provide complementary evidence, especially in settings of adaptive licensing of new drugs.

Extraction of Electronic Health Record Data in a Hospital Setting : Comparison of Automatic and Semi-Automatic Methods Using Anti-TNF Therapy as Model
- 2013
-
Ingår i: Basic & Clinical Pharmacology & Toxicology. - : Wiley. - 1742-7835 .- 1742-7843. ; 112:6, s. 392-400

Tidskriftsartikel (refereegranskat)abstract
- There is limited experience and methods for extractions of drug therapy data from electronic health records (EHR) in the hospital setting. We have therefore developed and evaluated completeness and consistency of an automatic versus a semi-automatic extraction procedure applied on prescribing and administration of the TNF inhibitor infliximab using a hospital EHR system in Karolinska University Hospital, Sweden. Using two different extraction methods (automatic and semi-automatic), all administered infusions of infliximab between 2007 and 2010 were extracted from a database linked to the EHR system. Extracted data included encrypted personal identity number (PIN), date of birth, sex, time of prescription/administration, healthcare units, prescribed/administered dose and time of admission/discharge. The primary diagnosis (ICD-10) for the treatment with infliximab was extracted by linking infliximab infusions to their corresponding treatment episode. A total of 13,590 infusions of infliximab were administered during the period of 2007 to 2010. Of those were 13,531 (99.6%) possible to link to a corresponding treatment episode, and a primary diagnosis was extracted for 13,530 infusions. Information on encrypted PIN, date of birth, time of prescription/administration, time of admission/discharge and healthcare unit was complete. Information about sex was missing in one patient only. Calculable information about dosage was extracted for 13,300 (98.3%) of all linked infusions. This methodological study showed the potential to extract drug therapy data in a hospital setting. The semi-automatic procedure produced an almost complete pattern of demographics, diagnoses and dosages for the treatment with infliximab.

- BackgroundAspects of survivorship, such as long-term ability to work, are increasingly relevant owing to the improved survival of patients with rectal cancer. The aim of this study was to assess risk and determinants of disability pension (DP) in this patient group. MethodsUsing Swedish national clinical and population-based registers, patients with stage I-III rectal cancer aged 18-61years in 1995-2009 were identified at diagnosis and matched with population comparators. Prospectively registered records of DP during follow-up were retrieved up to 2013. Non-proportional and proportional hazards models were used to estimate the incidence rate ratio (IRR) for DP annually and overall. Potential variations in risk by demographic and clinical factors were calculated, with relapse as a time-varying exposure. ResultsA total of 2815 patients were identified and compared with 13465 population comparators. During a median follow-up of 60 (range 0-10) years, 233 per cent of the relapse-free patients and 103 per cent of the population comparators received DP (IRR 240, 95 per cent c.i. 217 to 265). An increased annual risk of DP was evident almost every year until the tenth year of follow-up. Abdominoperineal resection was associated with an increased DP risk compared with anterior resection (IRR 144, 119 to 175). Surgical complications (IRR 133, 110 to 162) and reoperation (IRR 142, 109 to 184), but not radiotherapy or chemotherapy, were associated with risk of DP. ConclusionRelapse-free patients with rectal cancer of working age are at risk of disability pension. Higher than expected

- Aim: A population-based cohort and four randomized trials enriched with long-term register data were used to clarify if radiotherapy in combination with rectal cancer surgery is associated with increased risks of cardiovascular disease (CVD). Methods: We identified 14,901 rectal cancer patients diagnosed 1995-2009 in Swedish nationwide registers, of whom 9227 were treated with preoperative radiotherapy. Also, we investigated 2675 patients with rectal cancer previously randomized to preoperative radiotherapy or not followed by surgery in trials conducted 1980-1999. Risks of CVD overall and subtypes were estimated based on prospectively recorded hospital visits during relapse-free follow-up using multivariable Cox regression. Maximum follow-up was 18 and 33 years in the register and trials, respectively. Results: We found no association between preoperative radiotherapy and overall CVD risk in the register (Incidence Rate Ratio, IRR = 0.99, 95% confidence interval (CI) 0.92-1.06) or in the pooled trials (IRR = 1.07, 95% CI 0.93-1.24). We noted an increased risk of venous thromboembolism among irradiated patients in both cohorts (lRR(register) = 1.41, 95% CI 1.15-2.72; IRRtrials = 1.41, 95% CI 0.97-2.04), that remained during the first 6 months following surgery among patients treated 2006-2009, after the introduction of antithrombotic treatment (IRR6 (months) = 2.30, 95% CI 1.01-5.21). However, the absolute rate difference of venous thromboembolism attributed to RT was low (10 cases per 1000 patients and year). Discussion: Preoperative radiotherapy did not affect rectal cancer patients' risk of CVD overall. Although an excess risk of short-term venous thromboembolism was noted, the small increase in absolute numbers does not call for general changes in routine prophylactic treatment, but might do so for patients already at high risk of venous thromboembolism.

- Background: The number of working-age rectal cancer survivors is increasing due to early detection and improved treatment. However, work loss duration and predictors among them have not been studied thoroughly. Methods: We identified 3,438 patients with stage I-III rectal cancer, 18 to 61 years of age in the Swedish Colorectal Cancer Register 1996-2009. Information on work loss due to sick leave or disability pension was collected from 2 years before diagnosis to 5 years after (until December 31st, 2013). Incidence rate ratios (IRR) of work loss were estimated in a negative binominal model by clinical characteristics for the 1st and 2nd-5th years after diagnosis. Patients were stratified by prediagnostic work loss. Results: Patients without prediagnostic work loss (74%) experienced median 147 days (25th and 75th percentile: 55 and 281) of work loss during the 1st year after diagnosis. Work loss rates (2nd-5th years) were significantly increased among relapse-free patients diagnosed in stage III [IRR = 1.92; 95% confidence interval (CI), 1.52-2.43], operated with abdominoperineal resection (IRR = 1.26; 95% CI, 1.03-1.56), and treated with neoadjuvant (chemo) radiotherapy (IRR = 1.46; 95% CI, 1.06-2.02). Patients with prediagnostic work loss (26%) experienced median 336 days (25th and 75th percentile: 183 and 365) of work loss during the 1st year, and rates did not vary clinically till 5 years. Conclusion: Without prediagnostic work loss, disease-and treatment-related factors could help identify rectal cancer patients in need of early interventions to facilitate return to work. Impact: Clinical awareness around prediagnostic and postdiagnostic work loss and individualized cancer rehabilitation programs should be emphasized among cancer survivors.

- With today's excellent cure rates for Hodgkin lymphoma (HL), the number of long-term survivors is increasing. This study aims to provide a global assessment of late adverse effects for workingage HL survivors treated with contemporary protocols (combination chemotherapy and limited radiotherapy). From Swedish nationwide registers we identified 1017 HL survivors diagnosed in 2000-2009, aged 18-60 years (median 32) and surviving at least one year post-diagnosis, and 4031 age-,sex-, and calendar-year-matched population comparators. Incidence rate ratios (IRR) and 95% confidence intervals (95% CI) for outpatient visits and inpatient bed-days after the first year up to 14 years post-diagnosis (through 2013) were estimated across treatment subgroups, considering relapse-free time and using negative binomial regression. Scheduled outpatient visits for HL were excluded. The rate of outpatient visits was nearly double (IRR = 1.8, 95% CI: 1.6-2.0) that among comparators and higher rates persisted up to 10 years post-diagnosis. The rate of inpatient bed-days among relapse-free survivors was more than three-fold (IRR = 3.6, 95% CI: 2.74.7) that of comparators and the increase persisted up to four years post-diagnosis. Patients requiring 6-8 chemotherapy courses had higher rates of outpatient visits (IRR = 1.4, 95% CI: 1.11.7) and bed-days (IRR-4.7, 95% CI: 2.9-7.8) than patients treated with 2-4 courses+radiotherapy. Previously seldom reported reasons for the excess healthcare use included chest pain, keratitis, asthma, diabetes mellitus, and depression. Contemporary treatment, chemotherapy in particular, was associated with excess healthcare use among HL survivors during the first decade postdiagnosis. The reasons for healthcare visits reflected a wide range of disorders, indicating the need of broad individualized care in addition to specific screening programs.

- Context Recent reports suggest that rheumatoid arthritis (RA) may be a risk factor for venous thromboembolism (VTE), particularly in conjunction with hospitalization. Using hospitalization data to identify RA and VTE may identify patients when they are at elevated risk for other reasons, obscuring the incompletely understood underlying association between RA and VTE and leading to inappropriate institution or timing of interventions. Objective To estimate risks for VTE in patients with RA, including the relation of these risks to disease duration and hospitalization. Design, Setting, and Patients Prospective, population-based cohort study of 1 prevalent RA cohort (n = 37 856), 1 incident RA cohort (n = 7904), and matched general population comparison cohorts, all from Sweden, with follow-up from 1997 through 2010. Main Outcome Measure First-time VTE. Results Patients with prevalent RA were at greater risk of VTE than the general population (rate, 5.9 [95% CI, 5.1-6.6] vs 2.8 [95% CI, 2.6-3.1] per 1000 person-years (adjusted hazard ratio [HR], 2.0 [95% CI, 1.9-2.2]; P < .001). By the time of RA symptom onset, there was no statistically significant association between a history of VTE and RA (odds ratio, 1.2 [95% CI, 1.0-1.4]; P = .08; 150 events in the RA cohort vs 587 in the comparison cohort). Counting from RA diagnosis, an increased rate in the RA cohort vs the comparison cohort (3.8 [95% CI, 2.5-5.2] vs 2.4 [95% CI, 1.9-2.9] per 1000 person-years; HR, 1.6 [95% CI, 1.1-2.5]; P = .02) was detected within the first year and did not increase further during the first decade. Although rates for VTE following hospitalization were higher, the 1-year rate of VTE per 1000 person-years was not higher in the RA cohort than in the comparison cohort after hospital discharge (11.8 [95% CI, 8.6-15.1] vs 13.1 [11.3-14.8]; HR, 1.0 [95% CI, 0.7-1.4]; P = .90). The rates of VTE increased with age but were largely similar across sex and rheumatoid factor status, as were the HRs for VTE across age, sex, and rheumatoid factor status. Conclusions Compared with the general population, Swedish patients with RA had an elevated risk for VTE that was stable over the first 10 years after diagnosis. Although hospitalization was a risk factor for VTE the first year after discharge, the excess risk was not greater in patients with RA than in the general population.

- During recent years, a new field has appeared, in which the principles of life sciences and engineering are applied to the development of methods of regenerating human tissue and organs. Since the emergence of this interdisciplinary field, plastic surgeons have been deeply involved in its development, both in the early stages and in introducing the methods into clinical practice. The article consists in discussion of the possibilities these methods offer and the impact they may have on the field of plastic and reconstructive surgery.

- Objective: To explore the direct and Indirect costs in a cohort of 225 risperidone-treated patients with schizophrenia followed up annually during 5 years. Method: Data on costs for medication, hospitalization, sheltered living and productivity losses, as well as degree of social isolation, were collected. Results: The direct costs were dominated by hospitalization and sheltered living expenses, while drug costs only represented 7% of the direct costs. Indirect costs represented 43% of the total costs during the 5 years. About 12% worked full-time, and 12% worked part-time, implying large productivity losses. As a consequence of the national mental health care reform, a substantial shift of costs from hospital care to sheltered living took place on the national level, but the reduction of hospital days for the study patients over time was much larger suggesting that the switch from first to second generation compounds was therapeutically successful. A high degree of social isolation was seen, with more than 20% being completely without social contacts and 30% seeing friends/relatives less often than once a week. Conclusion: The economic costs of schizophrenia are high and driven by the need for assisted living and hospitalizations, together with productivity losses. In addition, the intangible costs, such as social contacts, are also high.

- Objective:To investigate pregnancy and perinatal outcomes in twin births among women with and without polycystic ovary syndrome (PCOS) diagnosis. Design: Population-based cohort study. Setting: Sweden. Population: We identified 20965 women with twin births between 1995 and 2009 of whom 226 had a PCOS diagnosis through linkage between the Swedish Medical Birth Register and the Swedish National Patient Register. Methods: Calculating risk ratios (RR) with 95% confidence intervals (CI) using a log-binomial regression model and hazard ratios (HR) with 95% CI for preterm birth. Main outcome measures: Preterm birth, low birthweight, caesarean section, pre-eclampsia, Apgar score <7 at 5minutes and perinatal mortality. Results: PCOS diagnosis in twin pregnancy was associated with increased risk of preterm delivery (51% versus 43%, RR 1.18 [95% CI 1.03-1.37]), particularly spontaneous preterm delivery (37% versus 28%; RR 1.30 [95% CI 1.09-1.55]) and very preterm birth (<32weeks) (14% versus 8%, RR 1.62 [95% CI 1.10-2.37]). Twins of PCOS mothers had more often low birthweight (48% versus 39%, adjusted RR 1.40 [95% CI 1.09-1.80]). This difference disappeared when adjusting for gestational age. No risk difference was found for caesarean section, pre-eclampsia, low 5-minute Apgar score or perinatal mortality. Conclusions: The risk of preterm delivery in twin pregnancies is increased by having a PCOS diagnosis. This should be considered in risk estimation and antenatal follow-up of twin pregnancies.

- BACKGROUND: Childhood-onset inflammatory bowel disease (IBD) might negatively impact academic school performance. We conducted a nationwide study to examine the association between childhood-onset IBD and school results. METHODS: Our study population was selected from Swedish health registers. In the National Patient Register (1990 to 2013), we identified 2827 children with IBD: Crohn's disease (CD), n = 1207, and ulcerative colitis (UC), n = 1370. Patients were matched with 10 reference individuals by age, sex, birth year, and place of residence (n = 28,235). Final compulsory school grades (0 to 320 grade points) and qualification for high school (yes or no) were obtained through the National School Register. Regression models controlling for socioeconomic factors were used to analyze the association of IBD with school performance. RESULTS: Children with IBD had a lower final grade point average (adjusted mean grade difference [AMGD] -4.9, 95% confidence interval [CI] -7.1 to -2.6) but not a significantly higher risk to not qualify for high school (odds ratio [OR] 1.14, CI 0.99-1.31). The results were similar in children with UC (AMGD -5.5, CI -8.7 to -2.3) and CD (AMGD -4.7, CI -8.2 to -1.2). Underperformance was more common in subsets of IBD children characterized by markers associated with long-standing active disease (eg, >30 inpatient days [AMGD-18.1, CI -25.8 to -10.4]). CONCLUSION: Most children with IBD achieve comparable results in the final year of compulsory school as their healthy peers. Care should be improved for the subgroup of children for which IBD has a stronger negative impact on school performance.

- Background: Growth retardation is well described in childhood-onset inflammatory bowel disease (IBD).Aims: To study if childhood-onset IBD is associated with reduced final adult height.Methods: We identified 4201 individuals diagnosed with childhood-onset IBD 1990-2014 (Crohn's disease: n = 1640; ulcerative colitis: n = 2201 and IBD-unclassified = 360) in the Swedish National Patient Register.Results: Patients with IBD attained a lower adult height compared to reference individuals (adjusted mean height difference [AMHD] -0.9 cm [95% CI -1.1 to -0.7]) and to their healthy siblings (AMHD -0.8 cm [-1.0 to -0.6]). Patients with Crohn's disease (CD) were slightly shorter than patients with ulcerative colitis (UC; -1.3 cm vs -0.6 cm). Lower adult height was more often seen in patients with pre-pubertal disease onset (AMHD -1.6 cm [-2.0 to -1.2]), and in patients with a more severe disease course (AMHD -1.9 cm, [-2.4 to -1.4]). Some 5.0% of CD and 4.3% of UC patients were classified as growth retarded vs 2.5% of matched reference individuals (OR 2.42 [95% CI 1.85-3.17] and 1.74 [1.36-2.22] respectively).Conclusion: Patients with childhood-onset IBD on average attain a slightly lower adult height than their healthy peers. Adult height was more reduced in patients with pre-pubertal onset of disease and in those with a more severe disease course.
