Healthcare personnel's working conditions relationship to risk behaviours for organism transmission
- 2021
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Healthcare personnel (HCP) often experience undesirable working conditions. Risk behaviours for organism transmission can lead to healthcare associated infections and risk behaviours has been described to be influenced by working conditions. Research is lacking regarding HCPs working conditions and its relation to risk behaviours for organism transmission which this thesis aims to investigate. Methods: Study I had a mixed-methods convergent design. Observations and interviews were performed with 79 HCP, i.e., registered nurses (RNs) and assistant nurses (ANs). First-line managers were interviewed about the unit´s overall working conditions. The qualitative and quantitative data were analysed separately and then merged. Study II was a cross-sectional study with 417 RNs and ANs. The questionnaire included: self-efficacy to aseptic care, structural empowerment (SE), work engagement (WE) and work-related stress (WRS). Correlational analysis and group comparisons were performed. Results: In Study I risk behaviours frequently occurred regardless of measurable and perceived working conditions. The HCP described e.g. staffing levels and interruptions to influence risk behaviours. In the statistical analyses, risk behaviours were more frequent in interrupted activities and when the HCP worked together. In Study II the HCP rated high levels of self-efficacy to aseptic care. Differences were found between self-efficacy and some of the grouped working condition variables and definite but small relationships were found between self-efficacy to aseptic care and SE/WE/WRS. Conclusion: The HCP rated high levels of self-efficacy to aseptic care, but on the other hand, risk behaviours frequently occurred irrespective of working conditions. Healthcare managers are responsible for HCPs work environment and should continuously work to promote sufficient working conditions and to increase HCPs understanding of risk behaviours, which consequently also promote patient safety.

Sleep disturbances : Consequences and comorbidities
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Sleep disorders are common in the general population, with insomnia and sleep-related breathing disorders being the most common disorders. Since sleep has many important functions, such as a role in consolidation of memories and learning, energy conservation, cardiovascular and immune system regulation, it is not surprising that the disruption of normal sleep may lead to negative health effects and various comorbidities. Aim: The overall aim of this thesis was to investigate the impact of disturbed sleep on various consequences and comorbidities. Methods and results: Papers I and II were based on the Sleep and Health in Women (SHE), a population-based prospective study of women, where a questionnaire was sent to women in 2000 and 2010. In paper I, the study cohort comprised 4,320 women <67 years of age who answered both questionnaires and had worked during the follow-up period. In women, having a long history of insomnia symptoms was associated with an increased risk of self-reported occupational accidents.In paper II, the 4,882 participants who answered the questions regarding nocturnal gastroesophageal reflux and snoring in both questionnaires were included in the study cohort. Women with nocturnal gastroesophageal reflux and snoring were at an increased risk of developing daytime sleepiness and to involuntarily fall asleep during the day. Paper III was based on the RHINE-cohort with participants from seven Northern European centers. The study cohort in paper III comprised the 2,568 smokers in the baseline study that also reported being smokers or former smokers in the follow-up study. It was found that having insomnia symptoms or excessive daytime sleepiness decreases the chance of long-term smoking cessation, and that smoking increases the risk of incident difficulties inducing sleep. Paper IV was the population-based, cross-sectional GA2LEN-survey which was conducted in four major Swedish cities. Paper IV included the 25,901 participants who answered questions regarding both snoring and insomnia symptoms. The combination of snoring and insomnia symptoms was associated with an increased risk of hypertension, asthma, chronic obstructive pulmonary disease, and daytime sleepiness. Conclusions: Disturbed sleep, due to varying causes, influences the risk of occupational accidents, on the chance of successful smoking cessation, on the risk of daytime sleepiness, hypertension, and obstructive lung disease. In clinical consultation, it is important to always inquire about disturbed sleep as it can have an impact on many aspects of health.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Smoking is associated with sleep disturbances. The aim of this study was to analyze whether sleep disturbances are predictors of smoking cessation and whether continued smoking is associated with the development of sleep disturbances. Methods: A questionnaire was sent to randomly selected men and women in Northern Europe in 1999-2001 (RHINE II) and was followed up by a questionnaire in 2010-2012 (RHINE III). The study population consisted of 2568 participants who were smokers at baseline and provided data on smoking at follow-up. Insomnia symptoms were defined as having difficulty initiating and/or maintaining sleep and/or early morning awakening >= 3 nights/week. Multiple logistic regression analyses were performed to calculate odds ratios (OR). Results: Subjects with difficulty initiating sleep (adjusted odds ratio; 95% confidence interval: 0.6; 0.4-0.8), difficulty maintaining sleep (0.7; 0.5-0.9), early morning awakening (0.6; 0.4-0.8), any insomnia symptom (0.6; 0.5-0.8) or excessive daytime sleepiness (0.7; 0.5-0.8) were less likely to achieve long-term smoking cessation after adjustment for age, BMI, pack-years, hypertension, diabetes, chronic bronchitis, rhinitis, asthma, gender and BMI difference. There was no significant association between snoring and smoking cessation. In subjects without sleep disturbance at baseline, continued smoking increased the risk of developing difficulty initiating sleep during the follow-up period compared with those that had quit smoking (adj. OR 1.7, 95% CI 1.2-2.3). Conclusions: Insomnia symptoms and excessive daytime sleepiness negatively predict smoking cessation. Smoking is a risk factor for the development of difficulty initiating sleep. Treatment for sleep disturbances should be included in smoking-cessation programs.

- Study Objectives: Insomnia and snoring are common sleep disorders. The aim was to investigate the association of having a combination of insomnia symptoms and snoring with comorbidity and daytime sleepiness. Methods: The study population comprised 25,901 participants (16-75 years, 54.4% women) from 4 Swedish cities, who answered a postal questionnaire that contained questions on snoring, insomnia symptoms (difficulties initiating and/or maintaining sleep and/or early morning awakening), smoking, educational level, and respiratory and nonrespiratory disorders. Results: Snoring was reported by 4,221 (16.2%), while 9,872 (38.1%) reported 1 insomnia symptom. A total of 2,150 (8.3%) participants reported both insomnia symptoms and snoring. The association with hypertension (adjusted odds ratio [OR], 1.4; 95% confidence interval [Cl], 1.2-1.6), chronic obstructive pulmonary disease (adjusted OR, 1.8; 95% CI, 1.3-2.4), asthma (adjusted OR, 1.9; 95% CI, 1.6-2.3), daytime sleepiness (adjusted OR, 7.9; 95% CI, 7.1-8.8), and the use of hypnotics (adjusted OR, 7.5; 95% CI, 6.1-9.1) was highest for the group with both insomnia symptoms and snoring. Conclusions: Participants with both snoring and insomnia run an increased risk of hypertension, chronic obstructive pulmonary disease, asthma, daytime sleepiness, and use of hypnotics. It is important to consider snoring in patients seeking medical assistance for insomnia and, vice versa, in patients with snoring inquiring about insomnia.

-
Ingår i: Science of the Total Environment. - : Elsevier. - 0048-9697 .- 1879-1026. ; 804
-
Tidskriftsartikel (refereegranskat)abstract
- Using one-night sleep recordings from 852 subjects all living in Uppsala, Sweden, the present study represents one of the largest polysomnography investigations into the association of the 29.53-day long lunar cycle with sleep among men and women and across a wide age range (22–81 years). Following the day after the new moon until the day of the full moon (also named the waxing period), the moon's illumination increases, and the timing of the meridian of the moon is gradually shifted from noontime toward midnight. In contrast, from the day after the full moon until the day of the new moon (also named the waning period), the moon's illumination decreases, and the timing of the meridian of the moon is gradually shifted from early night hours toward noontime. Thus, we focused on the contrast between the waxing and waning periods. Sleep duration was shorter on nights during the waxing period as compared to waning period (P < 0.001). In addition, a significant interaction effect of participants' sex with the lunar period on sleep was noted (P < 0.05). Men, but not women, exhibited lower sleep efficiency (P < 0.001 and P = 0.748, respectively) and were longer awake after sleep onset (P = 0.010 and P = 0.890, respectively) on nights during the waxing period. All associations were robust to adjustment for confounders (including regular sleep disturbances). Our findings suggest that the effects of the lunar cycle on human sleep are more pronounced among men. Based on the cross-sectional design of the study, no firm conclusions can be drawn on the causality of the relations.

- All people are different. All teachers are different. All students are different. They have different life situations, different study situations, and different preferences, conditions, and abilities. How can we take this diversity into account when we plan our teaching and exams? What situations should we prepare for? How can we help students focus on their learning and not on unnecessary obstacles we unconsciously introduce? If we make small efforts upfront, this lets us avoid much larger efforts later on when we are confronted with the reality of students in our class and their different needs.At this round table, let us discuss diversity in teaching and learning. During fall 2023, a pilot of the course “The Inclusive Classroom” was run at LTH, the Faculty of Engineering at Lund University. We present the compiled, most important take-aways of participants and instructors, in addition to individual case-studies. In a nutshell: There are a lot of easy things you can do that can already have large effects, and you are not alone: LTH has many resources to support you. Please join a supportive, engaged community and learn from and with us!

Tidskriftsartikel (refereegranskat)abstract
- Purpose To study changes in lung function among individuals with a risk of obstructive sleep apnoea (OSA), and if asthma affected this relationship. Methods We used data from the European Community Respiratory Health Survey II and III, a multicentre general population study. Participants answered questionnaires and performed spirometry at baseline and 10-year follow-up (n= 4,329 attended both visits). Subjects with high risk for OSA were identified from the multivariable apnoea prediction (MAP) index, calculated from BMI, age, gender, and OSA symptoms at follow-up. Asthma was defined as having doctor's diagnosed asthma at follow-up. Primary outcomes were changes in forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) from baseline to follow-up. Results Among 5108 participants at follow-up, 991 (19%) had a high risk of OSA based on the MAP index. Participants with high OSA risk more often had wheeze, cough, chest tightness, and breathlessness at follow-up than those with low OSA risk. Lung function declined more rapidly in subjects with high OSA risk (low vs high OSA risk [mean +/- SD]: FEV1 = - 41.3 +/- 24.3 ml/year vs - 50.8 +/- 30.1 ml/year; FVC = - 30.5 +/- 31.2 ml/year vs - 45.2 +/- 36.3 ml/year). Lung function decline was primarily associated with higher BMI and OSA symptoms. OSA symptoms had a stronger association with lung function decline among asthmatics, compared to non-asthmatics. Conclusion In the general population, a high probability of obstructive sleep apnoea was related to faster lung function decline in the previous decade. This was driven by a higher BMI and more OSA symptoms among these subjects. The association between OSA symptoms and lung function decline was stronger among asthmatics.

- Study Objectives: Whether short or insufficient sleep are risk factors for new-onset nocturnal gastroesophageal reflux (nGER). Methods: In this 10-year longitudinal study, adult general-population women in Uppsala, Sweden, answered questionnaires on sleep, nGER, and other conditions on 2 occasions. Participants at baseline totaled 6,790, while participants at follow-up totaled 4,925. "Short sleep" was defined as sleeping < 6 hours/night and "insufficient sleep" was defined as reporting an average actual sleep duration below 80% of the self-estimated need for sleep duration but without "short sleep." nGER was defined as reporting heartburn or acid reflux after going to bed sometimes, often, or very often. The confounding factors-age, body mass index, physical activity, caffeine intake, smoking habits, alcohol dependence, depression, anxiety, and snoring-were defined from the questionnaire. Results: At baseline, 839 participants reported short sleep and 1,079 participants were defined as having insufficient sleep. Both participants with insufficient sleep and short sleep had nGER more often than those with sufficient sleep (26% vs 17% vs 10%, respectively). At follow-up, a new onset of nGER was twice as common among those with insufficient or short sleep at baseline and follow-up, compared with those with sufficient sleep at baseline and follow-up, even after adjusting for confounding factors (odds ratio 2.0 [1.5-2.8], P <.001). Conclusions: Insufficient sleep and short sleep are associated with nGER. Persistent insufficient and/or short sleep independently increases the risk of developing nGER over a 10-year follow-up. Women seeking treatment for nGER should be questioned about their sleep habits to identify insufficient sleep as a possible causative factor.

Entangled in complexity : An ethnographic study of organizational adaptability and safe care transitions for patients with complex care needs
- 2024
-
Ingår i: Journal of Advanced Nursing. - : John Wiley & Sons. - 0309-2402 .- 1365-2648.

Tidskriftsartikel (refereegranskat)abstract
- Aim: The aim of this study was to visualize vulnerabilities and explore the dynamics of inter-professional collaboration and organizational adaptability in the context of care transitions for patients with complex care needs.Design: An ethnographic design using multiple convergent data collection techniques.Methods: Data collection involved document review, participant observations and interviews with healthcare and social care professionals (HSCPs). Narrative analysis was employed to construct two illustrative patient scenarios, which were then examined using the Functional Resonance Analysis Method (FRAM). Thematic analysis was subsequently applied to synthesize the findings.Results: Inconsistencies in timing and precision during care transitions pose risks for patients with complex care needs as they force healthcare systems to prioritize structural constraints over individualized care, especially during unforeseen events outside regular hours. Such systemic inflexibility can compromise patient safety, increase the workload for HSCPs and strain resources. Organizational adaptability is crucial to managing the inherent variability of patient needs. Our proposed ‘safe care transition pathway’ addresses these issues, providing proactive strategies such as sharing knowledge and increasing patient participation, and strengthening the capacity of professionals to meet dynamic care needs, promoting safer care transitions.Conclusion: To promote patient safety in care transitions, strategies must go beyond inter-professional collaboration, incorporating adaptability and flexible resource planning. The implementation of standardized safe care transition pathways, coupled with the active participation of patients and families, is crucial. These measures aim to create a resilient, person-centred approach that may effectively manage the complexities in care transitions.Implications: The recommendations of this study span the spectrum from policy-level changes aimed at strategic resource allocation and fostering inter-professional collaboration to practical measures like effective communication, information technology integration, patient participation and family involvement. Together, the recommendations offer a holistic approach to enhance care transitions and, ultimately, patient outcomes.

In pursuit of integrated care : Interprofessional collaboration in transitional care for older people with complex care needs
- 2023
-
Ingår i: Presented at the Nordic Conference in Nursing Research, Reykjavik, Iceland, October 2-4, 2023.
-
Konferensbidrag (refereegranskat)abstract
- Background:Contemporary healthcare systems are based on a reductionist, biomedical paradigm maladapted to meet the needs of an aging population with multimorbidity. Integrated care and interprofessional collaboration are suggested to connect the different parts of healthcare. However, how this can be realised is less understood.The aim of the study was to develop a deeper understanding of how interprofessional collaboration across care providers in transitional care is conducted to achieve integrated care for older people with complex care needs.Method:Using constructivist grounded theory, observations and interviews were conducted with healthcare and social care professionals (n=86) from a multidisciplinary and cross-stakeholder perspective in a region in Sweden.Results:Interprofessional collaboration in transitional care emerges as a continuum of "Moving from fragmentation to coupling and integration through collaborative efforts". On the lowest level of integration, professionals are working in organisational “silos” that are difficult to cross, as each specialist's expert knowledge is necessary for the vulnerable patient´s wellbeing. Patients´ perception of seamless care is facilitated by the mutual sharing of patient data across organizations through integrated information systems. The highest level of integration is consolidated as the interprofessional team collaborates on a pronounced common ground with a shared mental map of the goals of care, constructing unity for the older person and their family.Conclusion:To achieve seamless transitional care for older people with complex care needs, clear boundaries and liability areas are necessary, and actors in interprofessional teams are required to assume responsibility across conceivable gaps across organizations.

Interlacing the threads of seamless care : Interprofessional collaboration in care transitions for older people with complex care needs
- 2022
-
Ingår i: International Journal of Integrated Care. - : Ubiquity Press. ; , s. 360-360
-
Konferensbidrag (refereegranskat)abstract
- Introduction: Current healthcare systems are not optimally designed to meet the needs of aging populations. With shorter hospital stays, fewer hospital beds, and fragmentation of the healthcare system, older people with complex care needs are recognised as particularly vulnerable. This development further increases the demands on older people and their family to assume responsibility of own health, and to navigate through the healthcare system, knowing of when and where to seek help. In care transitions, an interprofessional collaboration across care providers is considered as a path to deliver seamless care. Still, it seems hard to achieve.Aim and Method: The aim of the study is to explore interprofessional collaboration in care transitions from inpatient care to home healthcare for older people with complex care needs.Care transitions involve a variety of healthcare teams across stakeholder boundaries. Hence, to study this extensive process, an explorative qualitative methodology was chosen, using Constructivist Grounded Theory. The sampling approach was guided by the continuous analysis of the collected data, utilizing a theoretical sampling. Fifty-nine multidisciplinary healthcare and social care professionals (HSCP) from different stakeholders were recruited. Document analysis, participatory observations and semi-structured interviews were conducted and analysed according to Charmaz.Results: Collaborating for a comprehensive care of older people with complex care needs emerges as interlacing the different threads of care to construct seamless care. Organizational gaps and legislations divide the HSCP as they strive to perform safe care within system boundaries, limited by interdependencies and communication organized in silos. Care is integrated as HSCP assumes accountability by going above and beyond their responsibility, constructing unity for the older person and their family. Seamless care is facilitated when information systems are integrated and by mutual sharing of patient data across organizations. To achieve seamless care for older people with complex care needs, HSCP need to adapt the delivery of care to the older person’s needs and resources instead of performing care as per organizational boundaries and conditions. Further, the autonomy of older people and their families need to be strengthened, including them as partners in the collaboration and coordination of care.Conclusions: Care efforts for older people with complex care needs are visualized as threads that together create a comprehensive care. To weave the threads together, a collaborative effort is required, strengthening the autonomy of the older person and their family, supported by integrated information systems that coordinate the care seamlessly.Implications and limitations: This study contributes to the understanding of interprofessional collaboration in care transitions of older people with complex care needs. Key strengths include the rich data and multidisciplinary perspective on providing integrated care. Limitations concern the absence of patient, family and informal caregivers’ involvement which should be included in further studies.

Konferensbidrag (refereegranskat)abstract
- BackgroundNavigating care transitions for patients with complex care needs represent a formidable challenge, where resilience becomes a crucial benchmark for quality and safety. There is a need to develop a healthcare infrastructure that not only reacts to disruptions but also proactively strengthens its capacity for continuity and patient safety. By addressing vulnerabilities and enhancing systemic responsiveness, the study illustrates how a coordinated, patient-centered approach is pivotal in building a healthcare infrastructure that can effectively navigate and adapt to challenges, thereby embodying the essence of resilient healthcare.ObjectiveThe aim of the study was to visualize vulnerabilities inherent in care transitions and to demonstrate how resilience—manifested through interprofessional collaboration and organizational adaptability—can fortify these critical junctures for patients with complex care needs.MethodsEmploying an ethnographic methodology, we engaged in document review, participant observations, and interviews with an array of healthcare and social care professionals involved in the care trajectory of patients with complex care needs. Narrative analysis was employed to construct two illustrative patient scenarios, which were then examined using the Functional Resonance Analysis Method (FRAM). Thematic analysis was subsequently applied to synthesize the findings.ResultsOur findings reveal that timing and precision variability during care transitions not only exacerbate vulnerabilities but also jeopardize patient safety. The inherent systemic rigidity, particularly during non-standard hours, amplifies the strain on resources and escalates the demands placed on care providers. In the face of patient needs' inherent unpredictability, the capacity of an organization to adapt is not just advantageous but essential. The crux of resilience in this context is interprofessional collaboration, which empowers healthcare teams to manage care proactively and navigate transitions more securely. Through collaborative practices, professionals are equipped to pool knowledge, predict fluctuations in patient conditions, and proactively coordinate responses to unexpected situations.ConclusionsWe advocate for a resilient model of care transition that is anchored in the collaborative synergy of healthcare teams, strategic resource management, and robust communication infrastructures. This model advocates for the vital contributions of frontline workers, patients, and their families, suggesting that their involvement is key in overcoming systemic obstacles and championing integrated, person-centered care. Our proposed pathway seeks to foster a healthcare environment where resilience is ingrained in the culture and practices, thereby ensuring safe, continuous, and responsive care transitions for all patients, particularly those with complex care needs.

Development and performance of a sleep estimation algorithm using a single accelerometer placed on the thigh : an evaluation against polysomnography
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Accelerometers placed on the thigh provide accurate measures of daily physical activity types, postures and sedentary behaviours, over 24 h and across consecutive days. However, the ability to estimate sleep duration or quality from thigh-worn accelerometers is uncertain and has not been evaluated in comparison with the 'gold-standard' measurement of sleep polysomnography. This study aimed to develop an algorithm for sleep estimation using the raw data from a thigh-worn accelerometer and to evaluate it in comparison with polysomnography. The algorithm was developed and optimised on a dataset consisting of 23 single-night polysomnography recordings, collected in a laboratory, from 15 asymptomatic adults. This optimised algorithm was then applied to a separate evaluation dataset, in which, 71 adult males (mean [SD] age 57 [11] years, height 181 [6] cm, weight 82 [13] kg) wore ambulatory polysomnography equipment and a thigh-worn accelerometer, simultaneously, whilst sleeping at home. Compared with polysomnography, the algorithm had a sensitivity of 0.84 and a specificity of 0.55 when estimating sleep periods. Sleep intervals were underestimated by 21 min (130 min, Limits of Agreement Range [LoAR]). Total sleep time was underestimated by 32 min (233 min LoAR). Our results evaluate the performance of a new algorithm for estimating sleep and outline the limitations. Based on these results, we conclude that a single device can provide estimates of the sleep interval and total sleep time with sufficient accuracy for the measurement of daily physical activity, sedentary behaviour, and sleep, on a group level in free-living settings.

- AimTo delineate and clarify the meaning of the concept of self-care monitoring from a patient perspective.MethodsA systematic search was performed in the databases ASSIA, CINAHL, PsycInfo, and PubMed (January 2016–September 2021). A selection of 46 peer-reviewed articles was included in the study and analysed using Rodgers’ Evolutionary Method for Concept Analysis.ResultsThe following four attributes were identified: Tracking symptoms, signs, and actions, Paying attention, Being confident, and Needing routines, creating a descriptive definition: “Self-care monitoring is an activity that means a person has to pay attention and be confident and needs routines for tracking symptoms, signs, and action.” The antecedents of the concept were shown to be Increased knowledge, Wish for independence, and Commitment. The concepts’ consequences were identified as Increased interaction, Perceived burden, and Enhanced well-being.ConclusionsThis concept analysis provides extensive understanding of self-care monitoring from a patient perspective. It was shown that the concept occurs when a person practices self-care monitoring at home either with or without devices. A descriptive definition was constructed and presented with exemplars to encourage practice of the concept in various healthcare settings and could be of relevance to people with chronic illnesses or other long-term conditions.

Aktivt åldrande - induviduellt anpassade måltidslösningar för hälsa och livskvalitet hos äldre : Förpackningskoncept
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Användardriven förpackningsdesign har varit fokus i arbetspaket 4. Detta har bland annat inneburit enkätstudier med över 90 seniorer i samarbete med PRO, etnografiska studier i hemmamiljö samt hanteringsstudier och fokusgrupper där förpackningar har testats och utvärderas. Konceptutvecklingen har således skett iterativt med slutanvändare och förfinats med hjälp av vunna konsumentinsikter. Även lärdommar från litteraturen och nyutgiven standard för lättöppnade förpackningar har legat till grund för arbetet. En ledstjärna har varit att måltiden är en social aktivitet som delas med andra, förpackningen och dess innehåll bör tilltala alla 5 sinnen och locka till aptit. Projektet har därför fokuserat både på funktionalitet och upplevelsen av måltiden. Viktiga insikter som tagits hänsyn till är förpackningens hanterbarhet, i synnerhet öppningsaspekten som påverkas av såväl den äldres handstyrka och fingerfärdighet samt storlek och utformning på förpackningens greppyta. Förpackningen bör vidare intuitivt förklara hur den ska användas (öppnas, värmas etc), och information bör ges med så lite text som möjligt. Genomtänkt textstorlek och kontrast är viktigt för att den äldre ska kunna ta till sig informationen på förpackningen.Insikterna från studierna har implementerats i förpackningskoncept för huvudmål, dessert och mellanmål I samarbete med arbetspaket 5 har förpackningarna modulanpassats efter gastronormsystemet för att möjliggöra skalbarhet och därmed optimal effektivitet i distributionskedjan.

- Study Objectives:Obstructive sleep apnea (OSA) is associated with an increased risk of cardiovascular disease. One contributory factor may be hemodynamic stress due to the negative intrathoracic pressure during each episode of apnea. Type B natriuretic peptide (BNP) is secreted by the cardiac ventricles in response to volume expansion and pressure load and the authors hypothesized that there would be an association between indices of OSA during the night and levels of BNP in the morning.Setting:Community-based in Uppsala, Sweden.Participants:There were 349 women who participated.Measurements and Results:Participants underwent full-night polysomnography and anthropometric measurements, and answered questionnaires about medical conditions and current medication. The morning after the polysomnography, blood samples were drawn for analysis of plasma BNP, C-reactive protein, creatinine, and hemoglobin. There was an increase in mean BNP as the severity of sleep apnea increased, increasing from a mean value of 8.5 ng/L among women with an apnea-hypopnea index (AHI) < 5 to 18.0 ng/L in women with an AHI = 30. Elevated BNP levels (= 20 ng/L) were found in 29.8% of the women, whereas 70.2% had normal levels. The odds ratio was 2.2 for elevated BNP levels for women with an AHI of 5-14.9 in relation to women with an AHI < 5, 3.1 for women with an AHI of 15-29.9, and 4.6 for women with an AHI = 30 after adjustment for age, body mass index, systolic blood pressure, antihypertensive drugs, and creatinine.Conclusions:There is a dose-response relationship in women between the severity of sleep apnea during the night and the levels of BNP in the morning.

- Proteomic‐based technologies offer new opportunities to identify proteins that might reflect the cardiometabolic stress caused by different aspects of sleep‐disordered breathing. We aimed to investigate whether severe obstructive sleep apnea and severe obstructive sleep apnea during rapid eye movement sleep are associated with changed levels of inflammatory and cardiac disease‐related proteins in a population‐based cohort of women. In the community‐based “Sleep and Health in Women” (SHE) cohort study, 400 women underwent polysomnography, anthropometric measurements and blood sampling. Two proteomic assays (Olink Proseek® Inflammation panel and Olink Proseek® Cardiovascular II panel), each measuring 92 proteins, were analysed in a subsample of 253 women. p‐Values were adjusted for multiple testing, with false discovery rate set at 10%. In unadjusted models, 57 proteins were associated with apnea−hypopnea index, 56 proteins with oxygen desaturation index and 64 proteins with rapid eye movement−apnea−hypopnea index. After adjustment for age, body mass index and plate, there were no significant associations between apnea−hypopnea index or oxygen desaturation index and any of the proteins. Severe obstructive sleep apnea during rapid eye movement sleep (rapid eye movement−apnea−hypopnea index ≥ 30) was associated with decreased levels of two anti‐inflammatory proteins; Sirt2 (q‐value .016) and LAP‐TGF‐β1 (q‐value .016). There was also a negative association between rapid eye movement−apnea−hypopnea index of ≥ 30 and Axin1 (q‐value .095), a protein thought to facilitate TGF‐β‐signalling. We conclude that severe obstructive sleep apnea during rapid eye movement sleep is associated with low levels of Sirt2, LAP‐TGF‐β1 and Axin1, anti‐inflammatory proteins involved in metabolic regulation and in the atherosclerotic process. For obstructive sleep apnea based on a whole night, the associations with cardiac and inflammatory proteins are weaker, and explained to a large extent by age and body mass index.

- BACKGROUND: An association between obstructive sleep apnea and the incidence of heart failure has been reported in men but not in women. The aim of this study was to investigate whether a combination of snoring and excessive daytime sleepiness, the two main symptoms of obstructive sleep apnea syndrome, was able to predict incident heart failure in a population-based sample of women.METHODS: The population-based cohort study Sleep and Health in Women (SHE; n = 5990 women born between 1901 and 1980) was used, with baseline questionnaire data from April 2000 relating to snoring, excessive daytime sleepiness, and covariates. Using data retrieved from the Swedish National Patient Register and Cause of Death Register, the follow-up of incident heart failure continued until 31 December 2011.RESULTS: Among women with both snoring and excessive daytime sleepiness at baseline, 5.3% developed heart failure during follow-up compared with 0.9% in the reference group with neither snoring nor excessive daytime sleepiness. After adjustment for age, waist circumference, smoking, alcohol, hypertension, diabetes, previous myocardial infarction, physical inactivity, depressive symptoms, menopausal status, and hormone replacement therapy, women with the combination of snoring and excessive daytime sleepiness had a twofold increase in the risk of incident heart failure (hazard ratio [HR] 2.2 95% confidence interval [CI] 1.1-4.4).CONCLUSION: Symptoms of obstructive sleep apnea, that is, the combination of snoring and excessive daytime sleepiness, are associated with an increased risk of developing heart failure in women.

- Study Objectives: Although obstructive sleep apnea (OSA) is associated with overall cardiovascular disease and mortality, the association with atherosclerotic cardiovascular disease is less clear, especially in women. Recently, it has been suggested that OSA during rapid eye movement (REM) sleep, associated with long apneas and deep desaturations, could have severe cardiometabolic consequences. The aim of this study was to investigate whether OSA during REM sleep is associated with early signs of atherosclerosis in a population-based sample of women. Methods: In the community-based "Sleep and Health in Women" (SHE) cohort study, 400 women underwent polysomnography, anthropometric measurements, blood sampling, blood pressure measurement, and answered questionnaires. Ten years later, 201 of the original participants, free of known atherosclerotic disease at baseline and without continuous positive airway pressure treatment for OSA, underwent a high-frequency ultrasound of the common carotid artery to assess the individual thickness of the layers of the artery wall. Results: Severe OSA during REM sleep (REM apnea-hypopnea index [AHI] >= 30) was associated with a thicker intima. This association was still significant after adjustment for age, body mass index, alcohol, and smoking, as well as for further adjustment for systolic blood pressure, low-density lipoprotein, C-reactive protein, and diabetes (ss-coefficient, 0.008; p-value, 0.022). The association between a REM AHI of >= 30 and intima thickness was also seen in women with no or mild OSA and normal non-REM AHI. Conclusions: In this study of a community-based sample of women, severe OSA during REM sleep was independently associated with early signs of atherosclerosis. Statement of Significance Individuals with obstructive sleep apnea run an increased risk of cardiovascular disease, but the relationship between obstructive sleep apnea and atherosclerotic diseases is still unclear, especially in women. Sleep apnea and respiration deteriorate during rapid eye movement (REM)-sleep and sleep apnea during REM sleep might have severe adverse effects. In this study of a community-based sample of women, severe sleep apnea during REM sleep was associated with early signs of atherosclerosis, defined as increased intima thickness, at 10 years of follow-up. The association was also seen in women with low overall apnea-hypopnea index, normally not considered for treatment of sleep apnea. This suggests that occurrence of frequent obstructive apneas during REM sleep has to be taken into consideration when diagnosing and treating sleep apnea.

- Rapid eye movement (REM) obstructive sleep apnea might be particularly harmful to the cardiovascular system. We aimed to investigate the association between sleep apnea during REM sleep and signs of atherosclerotic disease in the form of carotid intima thickness in a community-based sample of men and women and possible sex differences in this association. The association between sleep apnea during REM sleep and intima thickness was analysed cross-sectionally in women from the community-based "Sleep and Health in Women" (SHE) study (n = 253) and age- and body mass index (BMI)-matched men from the "Men in Uppsala; a Study of sleep, Apnea and Cardiometabolic Health" (MUSTACHE) study (n = 338). Confounders adjusted for were age, BMI, gender, alcohol, and smoking. All participants underwent a full-night polysomnography, high-resolution ultrasonography of the common carotid artery, anthropometric measurements, blood pressure measurements, and answered questionnaires. There was an association between sleep apnea during REM sleep and thicker carotid intima that remained after adjustment for confounding (adjusted β = 0.008, p = 0.032). The intima was increased by 9.9% in the group with severe sleep apnea during REM sleep, and this association between severe sleep apnea during REM sleep and increased intima thickness remained after adjustment for confounders (adjusted β = 0.043, p = 0.021). More women than men had severe sleep apnea during REM sleep; moreover, in sex-stratified analyses, the association between sleep apnea during REM sleep and intima thickness was found in women but not in men. We conclude that severe REM sleep apnea is independently associated with signs of atherosclerosis. When stratified by sex, the association is seen in women but not in men.

Sleep-disordered breathing in women : Associations with cardiovascular disease and the significance of sleep apnea during REM sleep
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Sleep-disordered breathing (SDB) is associated with an increased risk of cardiovascular disease, but it is unclear which elements of SDB that are most harmful to the cardiovascular system and whether the associations observed in men also apply to women.Aim: To investigate associations between different aspects of SDB and cardiovascular disease in womenMethods and results: All four papers were based on participants in “Sleep and Health in Women” (SHE), a population-based cohort study of women.Paper I is a cross-sectional study of 349 women with polysomnographic assessments of obstructive sleep apnea (OSA) and measurements of plasma BNP, clinically used as a marker of heart failure, in the morning. There was a dose-response relationship between the severity of OSA and levels of BNP.In Paper II, with a study population of 5,990 women, questionnaire data on symptoms of obstructive sleep apnea were combined with register data from the Swedish National Patient Register regarding a diagnosis of heart failure (mean follow-up 11.4 years). Women with the combination of snoring and daytime sleepiness had a two-fold increase in the risk of incident heart failure after adjustment for confounding.Paper III was based on 201 women without known cardiovascular disease, with a polysomnography at baseline, assessing OSA during REM sleep, and a carotid artery ultrasound with measurements of intima thickness at follow-up. Severe OSA during REM sleep was associated with a thicker carotid intima.Paper IV comprised 253 women with polysomnographic data on severe OSA and severe OSA during REM sleep, as well as proteomic analyses of cardiac and inflammatory proteins. After adjustment for confounding and multiple testing, severe OSA during REM sleep was associated with decreased levels of Sirt2, LAP-TGF-β1 and Axin1, while there were no significant associations for OSA based on a whole night and protein levels.Conclusions: Women with symptoms of OSA run an increased risk of developing heart failure and OSA is associated with increased levels of BNP. Severe OSA during REM sleep is associated with an early sign of atherosclerosis and reduced levels of proteins with anti-inflammatory effects linked to atherosclerosis and metabolic regulation.

- Objectives: Adherence to continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA) is crucial. Our aim was to identify protective and risk factors against the discontinuation of CPAP treatment in patients with OSA and to estimate the mortality risk in those who were non-adherent to CPAP therapy.Methods: This was a registry-based cohort study from 37 centers across Sweden with OSA patients on CPAP in the Swedevox Swedish national registry between July 2010 and March 2017.Results: In 16,425 patients (70.8% men) with complete follow-up data after 1.2 ± 0.8 years the adjusted relative risk ratio (aRRR) for the discontinuation of CPAP was 0.57 (95% confidence interval (CI) 0.50–0.65) for use of humidifier, 0.87 (95% CI 0.82–0.92) for increasing age per 10 years, 0.80 (95% CI 0.77–0.83) for increasing apnea hypopnea index (AHI) per 5 units/hour, and 0.96 (95% CI 0.95–0.97) per increased unit on the Epworth Sleepiness Scale (ESS). Increasing BMI was associated with increased adherence up to BMI 35. Women and patients with hypertension ran an increased risk of discontinuing CPAP treatment, aRRR 1.28 (95% CI 1.12–1.46) and 1.24 (95% CI 1.12–1.42) respectively. The adjusted hazard ratio (HR) for mortality was 1.74 (95% CI 1.32–2.28) among those who did not adhere to CPAP (median follow-up period 2.4 years after the one year adherence evaluation).Conclusion: Use of humidifier is associated with greater adherence to CPAP treatment. Other factors predicting adherence are increasing age, more severe OSA and overweight up to BMI 35, whereas female gender and coexisting hypertension are risk factors for discontinuation of CPAP. Failure to adhere to CPAP is associated with increased mortality.

- ObjectiveHabitual snoring is associated with fatigue, headaches and low work performance. This cross-sectional study aimed to investigate if snoring is affected by environmental factors such as home dampness and exposure to air pollution.SettingGeneral population sample from four Swedish cities.Participants25 848 participants from the Swedish part of the epidemiological Global Asthma and Allergy and European network of excellence study carried out in 2008. The participants completed a postal questionnaire on snoring and, indoor and outdoor environmental exposure as well as potential confounders including smoking, weight, height and educational level.ResultsOf the participants, 4211 (16.3%) were habitual snorers. Habitual snorers reported water damage (8.3% vs 7.0% p<0.0001), floor dampness (4.6% vs 3.8% % p<0.0001) and visible mould (5.2% vs 3.8% p<0.0001) in their homes more often than non-snorers. Habitual snorers stated being annoyed by air pollution more often than non-snorers with habitual snorers reporting being irritated with the air in their residential area to a higher extent (sometimes 16.2% vs 13.9%, and daily 4.6% vs 3.1%) as well as annoyance from traffic fumes (somewhat 19% vs 18.5% and very 5% vs 3.6%) (p<0.0001). These results remained significant after adjustment for age, body mass index, smoking history and educational level.ConclusionSnoring is more prevalent in subjects reporting home dampness and air pollution. These association should be confirmed in further research using objective measurements and a longitudinal approach.

Asthma and asthma-related comorbidity : effects on nocturnal oxygen saturation
- 2022

- STUDY OBJECTIVES: Nocturnal symptoms are very common in asthma, which is associated with worse sleep quality. The nocturnal oxygen saturation may be decreased in asthma; however, whether this association is dependent on nocturnal asthma symptoms, lung function, coexisting obstructive sleep apnea (OSA), or other asthma-related comorbidities is unknown. The objective of this study was to examine the effects of asthma, OSA, lung function, airway symptoms, and asthma-related comorbidities on the nocturnal oxygen saturation in a cross-sectional community-based population study.METHODS: In total, 395 women and 392 men underwent overnight polysomnography, performed spirometry, and completed questionnaires on airway symptoms and asthma-related comorbidities.RESULTS: Participants with asthma (n = 88) had a lower nocturnal oxygen saturation than those without asthma (93.8% vs 94.3%, P = .01) also after adjusting for comorbidity, age, body mass index, and smoking status (coefficient -0.38; CI -0.67, -0.10; P < .01). The nocturnal oxygen saturation was lower among participants with wheezing, nocturnal chest tightness, fixed airflow limitation, gastroesophageal reflux, obesity, and OSA than in those without these conditions. The associations between lower oxygen saturation and wheezing, forced expiratory volume in 1 second, gastroesophageal reflux, and apnea-hypopnea index were significant also after adjusting for age, sex, body mass index, and smoking status. Participants with both wheezing and OSA had a significantly lower nocturnal oxygen saturation (92.5 ± 0.5%) than participants with wheezing only (94.3 ± 0.3%) and OSA only (93.6 ± 0.2% %) (P < .01).CONCLUSIONS: Participants with asthma displayed a lower mean oxygen saturation during sleep, which could not be explained only by coexisting OSA or obesity. Also, asthma symptoms and lung function were associated with lower nocturnal oxygen saturation. The lower oxygen saturation seen in asthma is hence multifactorial in origin and is a result of the combination of symptoms, lung function, and comorbidity.CITATION: Sundbom F, Janson C, Ljunggren M, Lindberg E.

- STUDY OBJECTIVES: Obstructive sleep apnea (OSA) during rapid eye movement (REM) sleep is often characterized with more frequent and lengthy breathing events and greater oxygen desaturation than during other sleep stages. Current evidence suggests an association between OSA and cognitive decline, however whether OSA during REM sleep plays a vital role in this link is understudied.METHODS: A cross-sectional sample of 728 men and women (aged 59.1 ± 11.3 years) underwent a full night polysomnography for determining apnea-hypopnea index (AHI) and sleep stages. Trail Making Test (TMT) part A and B were conducted during the following day for assessing participants' cognitive function. Linear regression analyses were performed to test the possible association between AHI and AHI during REM sleep with TMT-A and B results. Similar analyses were carried out in a subsample involving participants aged ≥60 years with ≥30 min of REM sleep (n = 356).RESULTS: Despite a slight difference in TMT-B between participants with and without OSA (AHI ≥5 vs AHI <5, β-coefficient: 4.83, 95 % CI: [-9.44, -0.22], P = 0.040), no other association between AHI or REM-AHI and TMT results were found in the full sample. In older participants (aged ≥60 years), a REM-AHI ≥5 events/hour was associated with longer time taken to finish TMT-A (vs REM-AHI <5 events/hour, 3.93, [0.96, 6.90], P = 0.010). There was no association between REM-AHI and time taken to finish TMT-B in older participants.CONCLUSIONS: The results indicate that OSA during REM sleep may be of particular concern for attention-related cognitive function in older adults.

Tidskriftsartikel (refereegranskat)abstract
- SPECIES is an undulator-based soft X-ray beamline that replaced the old I511 beamline at the MAX II storage ring. SPECIES is aimed at high-resolution ambient-pressure X-ray photoelectron spectroscopy (APXPS), near-edge X-ray absorption fine-structure (NEXAFS), X-ray emission spectroscopy (XES) and resonant inelastic X-ray scattering (RIXS) experiments. The beamline has two branches that use a common elliptically polarizing undulator and monochromator. The beam is switched between the two branches by changing the focusing optics after the monochromator. Both branches have separate exit slits, refocusing optics and dedicated permanent endstations. This allows very fast switching between two types of experiments and offers a unique combination of the surface-sensitive XPS and bulk-sensitive RIXS techniques both in UHV and at elevated ambient-pressure conditions on a single beamline. Another unique property of the beamline is that it reaches energies down to approximately 27 eV, which is not obtainable on other current APXPS beamlines. This allows, for instance, valence band studies under ambient-pressure conditions. In this article the main properties and performance of the beamline are presented, together with selected showcase experiments performed on the new setup.
