ABSTRACT
To estimate the effect of a 3-year commitment to remain tobacco free on tobacco uptake among high school students in Sweden. The commitment is developed in the form of a contract between a child and a significant adult, constituting the core component of Tobacco-free Duo (T-Duo), a Swedish school-based tobacco prevention program. Secondary analysis of data from a cluster randomized controlled trial. Participants were 586 students in high schools assigned to the intervention arm of T-Duo. At inception, participants attended grade 7 (i.e., age 12-13). Only students who were tobacco naïve at baseline for the respective outcome and participated in all follow-ups were included. The exposure was defined as signing a 3-year contract with a significant adult, categorized as "stable contract" (3 years contract with the same contract partner), "unstable" (signed a contract sometime during follow-up but this was not sustained over time and/or with the same partner), and "no contract" at all during the intervention period. The primary outcome was having never tried cigarette smoking at the end of grade 9. Exposure and outcomes were self-reported in yearly questionnaires. Of 586 students, 321 (55%) held a stable contract, 204 (35%) an unstable contract, and 61 (10%) did not sign a contract at all. At the end of grade 9 (age 15-16), the relative risk (RR) to remain cigarette free was 1.11 (95% CI 1.00-1.22) (Number Needed to Treat = 10) among students in any type of contract compared to students that did not write a contract at all. The RRs for remaining tobacco free (secondary outcomes) ranged from 1.07 (0.98-1.16) for regular snus use to 1.16 (1.00-1.35) for any type of tobacco use. A commitment to remain tobacco free through a child-adult contract seems to exert a preventive effect on the uptake of tobacco use among Swedish adolescents over 3 school years. The current findings apply to a selected sample of both schools and students. Registration: Current Controlled Trials ISRCTN52858080 Date: January 4, 2019, retrospectively registered.

AIM: To investigate how NGNs perceived and applied an intervention for preventing stress-related ill health embedded in a transition-to-practice programme when entering their professional life. DESIGN: A qualitative exploratory descriptive design was selected for this study to gain insights and perspectives on the adoption and utilization of the intervention. METHODS: In this qualitative methodology process evaluation, semi-structured and audio-recorded interviews were conducted with a sample of 49 nurses. Data were collected between December 2016 and July 2017, and were sorted in NVivo 12 Plus, followed by thematic analysis. RESULTS: The analysis resulted in three change processes stimulated by the intervention: (a) Building acceptance of being new; (b) Gaining insight into professional development and health and (c) Practical steps for skills development, healthy habits and better-organized work. In addition to the three themes, barriers that hindered the progression of the processes were also described. Each process influenced the development of the others by stimulating a deeper understanding, motivation to change and courage to act. Several barriers were identified, including the use of cognitively demanding intervention tools, fatigue, high work demands, inconvenient work hours and a hostile social climate on the ward. CONCLUSION: This process evaluation showed that newly graduated nurses used knowledge from the intervention and adopted new behaviours largely in accordance with how the intervention was intended to work. IMPACT: When entering a new profession, it is crucial to receive a well-thought-out, structured and targeted introduction to the new professional role, tasks and work group. Nurses stated that the intervention increased their understanding of the role as new nurses and their insight into how to develop skills that promoted better functioning and recovery. The intervention also stimulated the development of new health behaviour and some new learning strategies.

AIM: To explore if and how nurses' perceived organizational support affects their ability to handle and resolve ethical value conflicts. DESIGN: A mixed methods design with a longitudinal questionnaire survey and focus group interviews. METHODS: A questionnaire survey in six hospitals in two Swedish regions provided data from 711 nurses responding twice (November-January 2019/2020 and November-January 2020/2021). A cross-lagged path model tested the mutual prospective influence between the organizational climate of perceived organizational support, frequency of ethical value conflicts, and resulting moral distress. Four focus group interviews were conducted with 21 strategically selected nurses (April-October 2021). Qualitative data collection and analysis were inspired by Grounded Theory. RESULTS: A climate of perceived organizational support was empowering, contributing to role security. It prospectively decreased the frequency of ethical value conflicts but not the moral distress when conflicts did occur. CONCLUSION: It is important to facilitate the development of perceived organizational support among nurses, but also to reduce the occurrence of ethical value conflicts that the nurses cannot resolve. IMPLICATIONS FOR THE PROFESSION: By ensuring a shared care ideology, good inter-professional relations within the entire care organization, providing clear and supportive organizational structures, and utilizing competence adequately, healthcare managers can facilitate and support the development of perceived organizational support among nurses. Nurses who are empowered by perceived organizational support are stimulated by and take pride in their work and experience the work as meaningful and joyful. IMPACT: The study addressed the question of whether healthcare organizations could support nurses to resolving ethical value conflicts, and thus reduce moral distress. Perceived organizational support is related to factors such as ideological caring alignment and supportive organizational preconditions. This study contributes specific knowledge about how healthcare organizations can empower nurses to effectively resolve ethical value conflicts and thereby reduce their moral distress. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

AIM: The aim of the present study was to describe nurse managers' perceptions of the provision of mentoring for newly graduated registered nurses (NGRNs) and its contribution to the work environment in a hospital setting. BACKGROUND: Nurse managers are responsible for the work environment and for supporting the staff's professional development, which includes giving NGRNs organizational support during their introduction to the workplace. Mentorship is one common way to provide support, but there is a lack of knowledge about how nurse managers view this support. DESIGN/METHOD: This was a qualitative descriptive study, using a semi-structured interview guide. Fifteen individual interviews with nurse managers were performed in hospital settings. The interview transcripts were analysed using qualitative content analysis. The COREQ guidelines and checklist were used. RESULTS: The results describe the nurse managers' perceptions of the provision of mentoring in three themes: Ensuring and sustaining mentoring for new nurses' needs is a struggle in the harsh reality of healthcare, Identifying mentors who are willing and possess the necessary competence for the assignment and Promoting a secure and attractive workplace by mentoring new nurses. CONCLUSIONS: Our study confirms that nurse managers are important in the provision of mentoring for NGRNs' learning and professional development. Mentoring has a positive spillover effect on the entire unit as a sustainable approach to securing and improving the work environment. Our study also identifies challenges for nurse managers to structure mentoring provision. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: This study highlights the importance of investment in mentoring for the NGRNs' professional development and for patient care. Support is needed from the top level of the organization, but how mentoring should be structured and facilitated needs to be investigated further.

Despite increasing sequencing efforts, numerous fish families still lack a reference genome, which complicates genetic research. One such understudied family is the sand lances (Ammodytidae, literally: "sand burrower"), a globally distributed clade of over 30 fish species that tend to avoid tidal currents by burrowing into the sand. Here, we present the first annotated chromosome-level genome assembly of the great sand eel (Hyperoplus lanceolatus). The genome assembly was generated using Oxford Nanopore Technologies long sequencing reads and Illumina short reads for polishing. The final assembly has a total length of 808.5 Mbp, of which 97.1% were anchored into 24 chromosome-scale scaffolds using proximity-ligation scaffolding. It is highly contiguous with a scaffold and contig N50 of 33.7 and 31.3 Mbp, respectively, and has a BUSCO completeness score of 96.9%. The presented genome assembly is a valuable resource for future studies of sand lances, as this family is of great ecological and commercial importance and may also contribute to studies aiming to resolve the suprafamiliar taxonomy of bony fishes.

BACKGROUND: Previous studies have shown that the rapid transition to emergency remote teaching due to the COVID-19 pandemic was challenging for healthcare teachers in many ways. This sudden change made them face ethical dilemmas that challenged their values and ethical competence. RESEARCH AIM: This study aimed to explore and gain a deeper understanding of the ethical dilemmas healthcare teachers faced during the COVID-19 pandemic. RESEARCH DESIGN: This was an inductive qualitative study using a hermeneutic approach. Semi-structured interviews were conducted and analysed thematically. PARTICIPANTS AND RESEARCH CONTEXT: Healthcare teachers (n = 20) from eight universities and universities of applied sciences in the Nordic and Baltic countries participated. ETHICAL CONSIDERATIONS: This study was based on the research ethics of the Norwegian National Research Ethics Committee for Medicine and Health Sciences and approved by the Norwegian Agency for Shared Services in Education and Research. FINDINGS: Healthcare teachers faced several ethical dilemmas due to restrictions during the COVID-19 pandemic. The analysis revealed three main themes: How should I deal with students' ill-being, and what can I as a teacher do?; What can I demand from myself and my students, what is good teaching?; How do I manage the heavy workload and everyone's needs, and who gets my time? CONCLUSIONS: This study highlights the importance of healthcare teachers' continuous need for pedagogic and didactic education, especially considering new technology and ethical issues. During the pandemic, the ethical consequences of remote teaching became evident. Ethical values and ethical dilemmas should be addressed in healthcare education programmes at different levels, especially in teacher education programmes. In the coming years, remote teaching will grow. Therefore, we need more research on this issue from an ethical perspective on its possible consequences for students and healthcare teachers.
ABSTRACT
Friends' and parents' tobacco use are strong predictors of tobacco uptake among adolescents, however the effectiveness of interventions based on public commitments and agreements to remain tobacco-free are not established. Here, we evaluated the effectiveness of the school-based Swedish program Tobacco-Free Duo (T-Duo) in preventing adolescents from initiating tobacco use (TOPAS study). T-Duo is a multi-component intervention witha formal agreement between a student and an adult partner to remain tobacco-free during the entire 3-year study period as core component. The standardized educational component of the same program was used as comparator (control). Primary outcome was the probability to "remain a non-user" of i) cigarettes and secondary outcomes ii) other types of tobacco at second (21-month) follow-up. Analysis was conducted according to Intention To Treat. In total 1776 adolescents (51% female) aged 12-13 in grade 7 from 34 participating high schools in Sweden were included at baseline in 2018, of which 1489 were retained after 21 months. The Risk Ratio (RR) of not having tried cigarettes 21-months after initiation of the intervention was 1.03(CI 0.98-1.08), Bayes Factor(BF) = 0.93, Absolute Risk Difference(ARD) = 3.1%. Similar associations were found for never smoked a whole cigarette and never use of other tobacco/nicotine products. There was a minimal reduction of tobacco use initiation among Swedish adolescents assigned to a multi-component intervention (T-Duo) compared to those assigned to standardized classroom education after 2 schoolyears. However, for most outcomes' findings were inconclusive and not reliably different from zero.

BACKGROUND: Evaluations, using questionnaires, of a two-year long CPD program for on-call consultant paediatricians, showed that the overall objective of the program was largely met. We stipulate that the coherency of the CPD program contributed to the learning. To gains a deeper understanding of the participants learning within and beyond the overall objectives of the program, we decided to conduct an interview study enrolling participants from the first two CPD courses. METHODS: Nine experienced paediatric consultants were interviewed 1-4 years after completing a coherent two-year long CPD program, focusing on what and how they learned. The interviews were audio-recorded and transcribed as text, analysed, and categorised using qualitative content analysis. RESULTS: What the participants learned: improved medical competences, greater confidence in the role of an on-call consultant, better understanding of the role of an on-call consultant and importance of professional networks. Several categories were outside the overall objective, at personal level: an understanding of one's own and other's competences, taking responsibility for one's own CPD and managing things one does not know. At professional level: more secure as an individual and with colleagues. How it was learned: relevant objectives, preparatory material and case discussions were important. Participants learned by preparing, repeating, reflecting, and participating actively, and by applying what they learned in clinical practice. The participants learned from one other over a period of two years, when they also got to know one another and created networks. A safe learning environment imposed demands and enabled participants to define their competence and learn accordingly. CONCLUSIONS: This study describes what and how on-call consultant paediatricians learned during a coherent two-year long CPD program. The learning took place within and beyond the framework of the overall objectives. The study suggests that evaluation methods based on objectives may be blind to important areas of learning and need to be combined with qualitative methods that examine a broad impact of learning. Taken together, the analysis of what and how the participants learned shows that they were better equipped to work as consultant on call and deal with the things they did not know.

Healthcare unit managers are pivotal to promote nurses' Perceived Organizational Support and hence to ensure nurses' health and well-being, as well as high-quality care. Despite this fact, there is a dearth of studies addressing how healthcare unit managers act and organize their work to promote nurses' Perceived Organizational Support and which working conditions enable them to do so. Through a mixed methods approach, comprising qualitative interviews and quantitative surveys among healthcare unit managers and nurses, this paper underscores that healthcare unit managers' availability to their nursing staff was essential for their ability to promote nurses' Perceived Organizational Support, and that responsive support from the care unit managers' superior management, administration, and managerial colleagues constituted enabling working conditions. Superior manager support strongly promoted the care unit manager's own Perceived Organizational Support, which, in turn, was positively correlated with nurses' organizational climate of Perceived Organizational Support.

AIM(S): This study aims to investigate care unit managers' perceptions of how the COVID-19 pandemic influenced their ability to support the nurses. BACKGROUND: The COVID-19 pandemic placed extreme pressure on health care organizations. More knowledge regarding how the pandemic influenced care unit managers' ability to support nurses is central to ensuring high-quality health care in future crises. METHOD(S): A mixed-methods study in Swedish hospitals with a survey (n = 128) and interviews (n = 20) with care unit managers. RESULTS: Approximately half of the managers reported having spent more time available to and supporting the nurses. Availability was positively predicted by their perceived organizational support while negatively by their job demands. These job demands concerned meeting staff anxiety and managing organizational restructuring. Full focus on direct patient care and strong professional and social support were important job resources. CONCLUSION(S): For care unit managers to effectively support the nurses during a crisis, they need proficient job resources and moderate job demands. Managers' perceived organizational support positively affects the quality of their crisis leadership. Creating arenas in which staff collegiality can form and develop is beneficial for the ability to meet future crises. IMPLICATIONS FOR NURSING MANAGEMENT: This study specifies important job resources that should be acknowledged and reinforced to strengthen the ability of care unit managers to actively support the nurses during a crisis.

INTRODUCTION: Simulation-based education is frequently used in transition programs for new graduate nurses. Simulation-based education is implemented as a measure to practice nursing skills, gain experience, and prepare nurses for caring in challenging situations, such as acute situations. However, concerns about the data supporting the use of simulation are obtained from small studies that do not use validated measurement scales. OBJECTIVE: This study aimed to explore the influence of simulation-based education on new graduate nurses' perceived ability to provide care in acute situations. METHODS: A total of 102 new graduate nurses participated in simulation-based education as a mandatory part of an introductory program. They completed a premeasurement and a postmeasurement using the Perception to Care in Acute Situations scale. The Wilcoxon signed-rank test and the paired samples t test were used to test the statistical significance of outcomes for the simulation-based education, with the alpha set at 0.05. Cohen's d formula was used to calculate the effect size. RESULTS: The Wilcoxon signed-rank test on the total scale score showed that simulation-based education resulted in a statistically significant change in the nurses' perceptions of their ability to care in acute situations (N = 99; Z = 7877; P < .001). The paired samples t test showed that the mean posteducation score was significantly higher (P < .001) in the total score. Cohen's d formula (-1.24) indicated a large effect size on the total score. DISCUSSION: Simulation-based education can provide an effective means of improving new graduate nurses' perceived ability to provide care in acute situations.

BACKGROUND: People with Parkinson's disease are less physically active than controls. It is important to promote physical activity, which can be assessed using different methods. Subjective measures include physical activity questionnaires, which are easy and cheap to administer in clinical practice. Knowledge of the psychometric properties of physical activity questionnaires for people with Parkinson's disease is limited. The aim of this study was to evaluate the test-retest reliability of physical activity questionnaires in individuals with Parkinson's disease without cognitive impairment. METHODS: Forty-nine individuals with Parkinson's disease without cognitive impairment participated in a test-retest reliability study. At two outpatient visits 8 days apart, the participants completed comprehensive questionnaires and single-item questions: International Physical Activity Questionnaire-Short Form (IPAQ-SF), Physical Activity Scale for the Elderly (PASE), Saltin-Grimby Physical Activity Level Scale (SGPALS) and Health on Equal Terms (HOET). Test-retest reliability was evaluated using the intraclass correlation coefficient (ICC), standard error of measurement (SEM), limits of agreement, weighted kappa or the Svensson method. RESULTS: Several of the physical activity questionnaires had relatively low test-retest reliability, including the comprehensive questionnaires (IPAQ-SF and PASE). Total physical activity according to IPAQ-SF had an ICC value of 0.46 (95% confidence interval [CI], 0.21-0.66) and SEM was 2891 MET-min/week. The PASE total score had an ICC value of 0.66 (95% CI, 0.46-0.79), whereas the SEM was 30 points. The single-item scales of SGPALS-past six months (SGPALS-6 m) and HOET question 1 (HOET-q1) with longer time frames (6 or 12 months, respectively) showed better results. Weighted kappa values were 0.64 (95% CI, 0.45-0.83) for SGPALS-6 m and 0.60 (95% CI, 0.39-0.80) for HOET-q1, whereas the single-item questions with a shorter recall period had kappa values < 0.40. CONCLUSIONS: Single-item questions with a longer time frame (6 or 12 months) for physical activity were shown to be more reliable than multi-item questionnaires such as the IPAQ-SF and PASE in individuals with Parkinson's disease without cognitive impairments. There is a need to develop a core outcome set to measure physical activity in people with Parkinson's disease, and there might be a need to develop new physical activity questionnaires.

BACKGROUND: People with Parkinson's disease (PD) have described their walking difficulties as linked to activity avoidance, social isolation, reduced independence and quality of life. There is a knowledge gap regarding predictive factors of perceived walking difficulties in people with PD. Such knowledge could be useful when designing intervention studies. This study aimed to investigate how perceived walking difficulties evolve over a 3-year period in people with PD. A specific aim was to identify predictive factors of perceived walking difficulties. METHODS: One hundred forty-eight people with PD (mean age 67.9 years) completed the Generic Walk-12 (Walk-12G) questionnaire (which assesses perceived walking difficulties) at both baseline and the 3-year follow-up. Paired samples t-test was used for comparing baseline and follow-up mean scores. Multivariable linear regression analyses were used to identify predictive factors of perceived walking difficulties. RESULTS: Perceived walking difficulties increased after 3 years: mean Walk-12G score 14.8 versus 18.7, p < 0.001. Concerns about falling was the strongest predictor (ß = 0.445) of perceived walking difficulties, followed by perceived balance problems while dual tasking (ß = 0.268) and pain (ß = 0.153). Perceived balance problems while dual tasking was the strongest predictor (ß = 0.180) of a change in perceived walking difficulties, followed by global cognitive functioning (ß = - 0.107). CONCLUSIONS: Perceived walking difficulties increase over time in people with PD. Both personal factors (i.e. concerns about falling) and motor aspects (i.e. balance problems while dual tasking) seem to have a predictive role. Importantly, our study indicates that also non-motor symptoms (e.g. pain and cognitive functioning) seem to be of importance for future perceived walking difficulties. Future intervention studies that address these factors need to confirm their preventative effect on perceived walking difficulties.

BACKGROUND: Social networks (SN) have been proven to be instrumental for healthy aging and function as important safety nets, particular for older adults in low and middle-income countries (LMICs). Despite the importance of interpreting health outcomes in terms of SN, in many LMICs - including Indonesia - epidemiological studies and policy responses on the health effects of SN for aging populations are still uncommon. Using outcome-wide multi-method approaches to longitudinal panel data, this study aims to outline more clearly the role of SN diversity in the aging process in Indonesia. We explore whether and to what degree there is an association of SN diversity with adult health outcomes and investigate potential gender differences, heterogeneous treatment effects, and effect gradients along disablement processes. METHODS: Data came from the fourth and fifth waves of the Indonesian Family Life Survey fielded in 2007-08 and 2014-15. The analytic sample consisted of 3060 adults aged 50+ years. The primary exposure variable was the diversity of respondents' SN at baseline. This was measured through a social network index (SNI), conjoining information about household size together with a range of social ties with whom respondents had active contact across six different types of role relationships. Guided by the disablement process model, a battery of 19 outcomes (8 pathologies, 5 impairments, 4 functional limitations, 2 disabilities) were included into analyses. Evidence for causal effects of SN diversity on health was evaluated using outcome-wide multivariable regression adjustment (RA), propensity score matching (PSM), and instrumental variable (IV) analyses. RESULTS: At baseline, 60% of respondents had a low SNI. Results from the RA and PSM models showed greatest concordance and that among women a diverse SN was positively associated with pulmonary outcomes and upper and lower body functions. Both men and women with a high SNI reported less limitations in performing activities of daily living (ADL) and instrumental ADL (IADL) tasks. A high SNI was negatively associated with C-reactive protein levels in women. The IV analyses yielded positive associations with cognitive functions for both men and women. CONCLUSIONS: Diverse SN confer a wide range of strong and heterogeneous long-term health effects, particularly for older women. In settings with limited formal welfare protection, intervening in the SN of older adults and safeguarding their access to diverse networks can be an investment in population health, with manifold implications for health and public policy.

The aim of this study was to evaluate the use of optical coherence tomography (OCT) to identify and assess visual field defects caused by primary damage to the optic radiation in individuals with spastic cerebral palsy (CP). Ten individuals with spastic CP (six females, four males, with a median age of 21 years [range 17-38y]) had their brain lesions documented with conventional magnetic resonance imaging (MRI) and diffusion-weighted MRI fibre tractography. Their macular ganglion cell layer (GCL) and inner plexiform layer (IPL) were examined with OCT and their visual fields were plotted. All participants had good visual acuity and were able to cooperate with the MRI and OCT examinations, as well as undergoing reliable perimetry. We found focal thinning of the GCL+IPL and corresponding homonymous visual field defects in individuals with brain damage affecting the optic radiation. We used GCL+IPL sector asymmetry as a sensitive OCT parameter to identify focal visual field defects. We observed no such sector asymmetry in GCL+IPL, or focal visual field defects, in individuals with normal MRI optic radiation imaging. Lesions affecting the optic radiation cause retrograde trans-synaptic degeneration of retinal ganglion cells. OCT examination of the GCL in the macula identified corresponding focal damage to the optic radiation in individuals with spastic CP and can be used to predict focal visual field defects. WHAT THIS PAPER ADDS: Spastic cerebral palsy (CP) may be associated with damage to the optic radiation. Damage to the optic radiation causes retrograde trans-synaptic degeneration (RTSD). RTSD can be mapped using optical coherence tomography. Ganglion cell topography can predict visual field defects in individuals with spastic CP.

BACKGROUND AND PURPOSE: Knowledge of predictive factors can foster the development of preventive approaches. This study examined how prevalence and severity of fall-related activity avoidance evolve over a 3-year period in people with Parkinson disease (PD). A specific aim was to identify predictive factors of fall-related activity avoidance (ie, modified Survey of Activities and Fear of Falling in the Elderly [mSAFFE] scores) after 3 years. METHODS: The sample included 151 people with PD (mean [SD] age: 68 [8.8] years). The mSAFFE score was the dependent variable in multivariable linear regression analyses, with 17 potential predictors. On the basis of a collinearity check, 2 models studying various risk factors were developed. Model 1 included concerns about falling and model 2 walking difficulties. RESULTS: After 3 years, more participants reported fall-related activity avoidance, that is, 34% versus 50% (P < 0.001). Regression model 1 explained 63% of the variance. The strongest predictive factor was concerns about falling (standardized regression coefficient, ß = 0.589), followed by pain (ß = 0.161), unsteadiness while turning (ß = 0.137), and age (ß = 0.136). These variables remained significant when adjusting for mSAFFE baseline scores.In model 2 (explained 50% of the variance), the strongest predictive factor was perceived walking difficulties (ß = 0.392), followed by age (ß = 0.238), unsteadiness while turning (ß = 0.198), and pain (ß = 0.184). Unlike the other factors, walking difficulties were not significant when adjusting for mSAFFE baseline scores. DISCUSSION AND CONCLUSIONS: Fall-related activity avoidance increased over time in people with PD. If fall-related activity avoidance is to be targeted, this study suggests that interventions should address concerns about falling, pain, unsteadiness while turning, and walking difficulties.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A310).

PURPOSE: To analyze the ganglion cell layer and inner plexiform layer (GCL+) thickness in children born extremely preterm and control children. METHODS: A study of 6.5-year-old children born before the gestational age of 27 weeks and age-matched controls. The GCL+ thickness and foveal depth (FD) were analyzed in a single optical coherence tomography B-scan. Association with neonatal risk factors and sex was investigated. Extremely preterm was divided into no, mild, and severe retinopathy of prematurity, retinopathy of prematurity treatment, and no, mild, and severe intraventricular hemorrhage. RESULTS: Adequate measurements were obtained from 89 children born extremely preterm and 92 controls. Extremely preterm children had increased total (5 µm, P < 0.001) and central (21 µm, P < 0.001) GCL+ thickness and reduced FD (-53 µm, P < 0.001) compared with controls. Extremely preterm children receiving retinopathy of prematurity treatment had increased GCL+ thickness and reduced FD compared with other subgroups. Sex and gestational age were associated with increased central GCL+ thickness and reduced FD. Reduced total GCL+ thickness was associated with severe intraventricular hemorrhage. CONCLUSION: Extremely preterm birth can cause incomplete extrusion of the GCL+ and reduced FD. Retinopathy of prematurity treatment, gestational age, and male sex were associated to increased central GCL+ thickness and reduced FD, while severe intraventricular hemorrhage was associated with reduced total GCL+ thickness.

BACKGROUND: The purpose was to study the macular ganglion cell- inner plexiform layer (GC-IPL) thickness in healthy 6.5 year- old Swedish children using Optical Coherence Tomography (OCT) and to study topography symmetry within eyes and between eye pairs. METHODS: A total of 181 eyes of 92 healthy children (39 girls, 53 boys) aged 6.5 and serving as a term-born control group in the Extremely Preterm Infants in Sweden Study (EXPRESS), were examined with Cirrus HD-OCT. Main outcome measures were average and minimum values of GC-IPL thickness of the device's predefined macular sectors. Single sectors, combined sectors defined as superior and inferior hemispheres and temporal and nasal sectors were evaluated. Intra-individual GC-IPL thickness between eye pairs was analyzed. Visual acuity, refraction and general cognition were assessed and correlated to GC-IPL outcome. RESULTS: Eighty-five children completed the OCT examination and 155 out of 181 scans (86%) were analyzed. The mean average GC-IPL thickness was 85.9 µm (± 5.3; 5th and 95th percentiles were 76.0 and 94.6 µm). The mean minimum GC-IPL thickness was 83.6 µm (± 4.9; 5th and 95th percentiles were 75.4 and 92.3 µm). The difference in thickness between nasal and temporal sectors and between superior and inferior hemisphere sectors were less than 2 µm. The difference between average GC-IPL thickness and minimum GC-IPL thickness was 2.3 µm (± 1.9; 5th and 95th percentiles were 0.0 and 6.0 µm). The difference between the thickest and thinnest sector within eye was 6.4 µm (± 2.2; 5th and 95th percentiles were 3.0 and 10.0 µm). There was a moderate correlation in the difference between the nasal combined and the temporal combined sectors within eye pairs (p < 0.0001, Spearman's ρ 0.58). The average GC-IPL thickness was weakly positively correlated with SE (spherical equivalent; combined sphere and ½ cylinder) (p = 0.031, Spearman's ρ 0.23). CONCLUSIONS: This study provides normative GC-IPL thickness values for healthy 6.5 year- old Swedish children. The GC-IPL thickness variations within eyes and within eye pairs are generally small. It could therefore be assumed that larger variations are sensitive markers of focal GC-IPL thinning due to damage to the primary visual pathways in children.

We explored subjective well-being in two groups of young adult participants diagnosed with either schizotypal disorder (Sd) (n = 29) or Asperger syndrome/autism spectrum disorder (As/ASD) (n = 22). Well-being was impaired in both groups and was lower in the Sd group than in the As/ASD group. Furthermore, there was a negative correlation between well-being and the presence of self-disorders. The negative effect of self-disorders on well-being was still significant when adjusted for diagnosis, age and gender, and level of function. The present findings point toward clinically important disorder-specific differences in the nature of impaired well-being between the Sd group and the As/ASD group, as there seems to be a self-disorder-driven additional contribution to impaired subjective well-being within the schizophrenia spectrum. These findings further nuance the understanding of fundamental and clinically important qualitative differences between the schizophrenia spectrum and the autism spectrum.

BACKGROUND: External housing-related control beliefs (HCB) and general self-efficacy (GSE) influence different health outcomes in the general ageing population, but there is no information of their role in people ageing with Parkinson's disease (PD). This study aimed to longitudinally assess the role of external HCB and GSE on the association between housing accessibility and activities of daily living (ADL) among people ageing with PD. METHODS: Baseline and 3-year follow-up data on 130 community-living participants from the Swedish project 'Home and Health in People Ageing with PD' were collected. Assessments addressed housing accessibility, external HCB, GSE, generic ADL and ADL specific to PD. The moderating effects of external HCB and GSE were assessed by including an interaction term in multivariable logistic regression. RESULTS: There were statistically significant interactions between housing accessibility and GSE on ADL (p = 0.03), and housing accessibility and external HCB on PD specific ADL (p = 0.03). After stratifying the analyses by GSE, housing accessibility problems led to more dependence and difficulty in ADL in participants with low GSE (OR 1.14; 95% CI 1.02-1.28). After stratifying by external HCB, housing accessibility increased dependence and difficulty in PD specific ADL in participants with low external HCB (OR 1.35; 95% CI 1.03-1.76). DISCUSSION: The results suggest that housing accessibility predicts ADL in people with PD with GSE and external HCB playing a moderating role for generic ADL and ADL specific to PD, respectively. Further longitudinal studies should validate these findings and explore their potential application in PD-related care and rehabilitation.
