Comparison of student nurses' expectations and newly qualified nurses' experiences regarding clinical practice: A secondary analysis of a cross-sectional survey.

AIM: To compare student nurses' expectations and newly qualified nurses' experiences regarding clinical practice in Switzerland 1 year after graduation. DESIGN: A secondary explorative analysis of a cross-sectional survey. METHODS: The data were sourced from the Swiss National Graduate Survey of Health Professionals covering six universities of applied sciences between 2016 and 2019, with information on three cohorts of bachelor student nurses, with a 1-year follow-up between each year. The participants were 533 bachelor-prepared nursing graduates. RESULTS: The student nurses' overall expectations included the following top two prioritized aspects: 'contributing to something important' and 'adequate time to spend with patients'. Newly graduated nurses' clinical practice experiences demonstrated that not all expectations were met 1 year after graduation. The largest gaps were found in 'adequate time to spend with patients', 'work-life balance' and experiencing 'good management'. CONCLUSION: The most crucial expectation gaps are related to having sufficient time to spend with patients and a good work-life balance. The most important result is whether there is a shortage of places for nurses to work rather than the oft-cited shortage of nurses. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The expectations of Swiss newly qualified nurses can be better met by an assessment in the first year about which individual perceptions of workplace characteristics cause them to make choices to change something about their work, affect their job satisfaction or influence their intention to stay. IMPACT: Few of the student nurses' expectations were met 1 year after graduation, therefore Swiss healthcare institutions should improve needs assessments to strengthen the nurse workforce starting early in employment. The results underscore the importance of a constructive management culture, such as that in magnet hospitals in the United States which underpins the philosophy of changing in nursing. The results can be used internationally as a benchmark and as a basis for introducing potential interventions for nurse retention. REPORTING METHOD: This study was reported following the Standardized Reporting of Secondary Data Analyses Checklist. PATIENT OR PUBLIC CONTRIBUTION: There were no patient or public contributions. TRIAL AND PROTOCOL REGISTRATION: This study has not been registered.

Changes in socioeconomic resources and mental health after the second COVID-19 wave (2020-2021): a longitudinal study in Switzerland.

BACKGROUND: During the 2020/2021 winter, the labour market was under the impact of the COVID-19 pandemic. Changes in socioeconomic resources during this period could have influenced individual mental health. This association may have been mitigated or exacerbated by subjective risk perceptions, such as perceived risk of getting infected with SARS-CoV-2 or perception of the national economic situation. Therefore, we aimed to determine if changes in financial resources and employment situation during and after the second COVID-19 wave were prospectively associated with depression, anxiety and stress, and whether perceptions of the national economic situation and of the risk of getting infected modified this association. METHODS: One thousand seven hundred fifty nine participants from a nation-wide population-based eCohort in Switzerland were followed between November 2020 and September 2021. Financial resources and employment status were assessed twice (Nov2020-Mar2021, May-Jul 2021). Mental health was assessed after the second measurement of financial resources and employment status, using the Depression, Anxiety and Stress Scale (DASS-21). We modelled DASS-21 scores with linear regression, adjusting for demographics, health status, social relationships and changes in workload, and tested interactions with subjective risk perceptions. RESULTS: We observed scores above thresholds for normal levels for 16% (95%CI = 15-18) of participants for depression, 8% (95%CI = 7-10) for anxiety, and 10% (95%CI = 9-12) for stress. Compared to continuously comfortable or sufficient financial resources, continuously precarious or insufficient resources were associated with worse scores for all outcomes. Increased financial resources were associated with higher anxiety. In the working-age group, shifting from full to part-time employment was associated with higher stress and anxiety. Perceiving the Swiss economic situation as worrisome was associated with higher anxiety in participants who lost financial resources or had continuously precarious or insufficient resources. CONCLUSION: This study confirms the association of economic stressors and mental health during the COVID-19 pandemic and highlights the exacerbating role of subjective risk perception on this association.

Musculoskeletal pain in health professionals at the end of their studies and 1 year after entry into the profession: a multi-center longitudinal questionnaire study from Switzerland.

BACKGROUND: Musculoskeletal pain, especially back pain, is common among health care professionals (HP). For prevention purposes, it is important to know whether HP develop their symptoms before or after entering the health care workforce. Cross-sectional studies among HP cannot answer this question. This follow-up study measures the prevalence and individual course of musculoskeletal pain among full-time HP students at the end of their studies and one year after entering the health care workforce. METHOD: Self-reported one-year prevalence for low back pain, neck/shoulder pain, pain in arms/hands, and pain in legs/feet was collected at two timepoints from 1046 participating HP using an online questionnaire. Participants were asked whether their musculoskeletal pain was related to study or work conditions. Generalized estimating equation (GEE) models of the binomial family with log link were used to estimate adjusted prevalence and corresponding normal based 95% confidence intervals were derived using the bootstrap method with 1000 replications. RESULTS: The prevalence of low back pain as well as neck and shoulder pain was very high at baseline and follow-up in all full-time students and later HP. Prevalence for pain in arms/hands, legs/feet was low and there were significant differences between the professions. HP clearly associated their low back pain and neck/shoulder pain with study and work conditions; HP strongly associated pain in arms/hands, legs/feet only with work conditions. CONCLUSION: Many HP suffer from back/neck/shoulder pain already as students before starting their professional career. The prevention of back/neck/shoulder pain must be part of the education of all health professions at universities. As an example of best practice, universities should incorporate ergonomic measures and exercises into the daily routine of training health professionals. The effects of physically demanding professional tasks on the upper and lower extremities need to be investigated in further studies to take preventive measures.

A Multi-component Intervention (NEXpro) Reduces Neck Pain-Related Work Productivity Loss: A Randomized Controlled Trial Among Swiss Office Workers.

Purpose Neck pain is common among office workers and leads to work productivity loss. This study aimed to investigate the effect of a multi-component intervention on neck pain-related work productivity loss among Swiss office workers. Methods Office workers, aged 18-65 years, and without serious neck-related health problems were recruited from two organisations for our stepped-wedge cluster randomized controlled trial. The 12-week multi-component intervention included neck exercises, health-promotion information, and workplace ergonomics. The primary outcome of neck pain-related work productivity loss was measured using the Work Productivity and Activity Impairment Questionnaire and expressed as percentages of working time. In addition, we reported the weekly monetary value of neck pain-related work productivity loss. Data was analysed on an intention-to-treat basis using a generalized linear mixed-effects model. Results Data from 120 participants were analysed with 517 observations. At baseline, the mean age was 43.7 years (SD 9.8 years), 71.7% of participants were female (N = 86), about 80% (N = 95) reported mild to moderate neck pain, and neck pain-related work productivity loss was 12% of working time (absenteeism: 1.2%, presenteeism: 10.8%). We found an effect of our multi-component intervention on neck pain-related work productivity loss, with a marginal predicted mean reduction of 2.8 percentage points (b = -0.27; 95% CI: -0.54 to -0.001, p = 0.049). Weekly saved costs were Swiss Francs 27.40 per participant. Conclusions: Our study provides evidence for the effectiveness of a multi-component intervention to reduce neck pain-related work productivity loss with implications for employers, employees, and policy makers.Trial Registration ClinicalTrials.gov, NCT04169646.

Safety and Feasibility of Immunoadsorption with Heparin Anticoagulation in Preparation of ABO-Incompatible Kidney Transplantation: A Retrospective Single-Center Study.

Introduction: Immunoadsorption (IA) of isohemagglutinins is an often-crucial procedure in preparation of major ABO blood group-incompatible living donor kidney transplantation (ABOi LDKT). Standard citrate-based anticoagulation during the procedure has potential disadvantages for distinct patient groups. In this study, we report our experience with an alternative anticoagulation scheme using heparin during IA for selected patients. Methods: We conducted a retrospective analysis of all patients who underwent IA with heparin anticoagulation between February 2013 and December 2019 at our institution with focus on the safety and efficacy of the adapted procedure. For further validation, we compared graft function, graft survival, and overall survival with those of all recipients of living donor kidney transplants with or without pretransplant desensitizing apheresis for ABO antibodies at our institution during the same period. Results: In thirteen consecutive patients prepared for ABOi LDKT with IA with heparin anticoagulation, no major bleeding or other significant complications were observed. All patients achieved sufficient isohemagglutinin titer reduction to proceed to transplant surgery. Graft function, graft survival, and overall survival did not significantly differ from patients treated with standard anticoagulation for IA or ABO compatible recipients of living donor kidneys. Conclusion: IA with heparin in preparation of ABOi LDKT is safe and feasible for selected patients after internal validation.

Frequency, reactivity and evolution of human leukocyte antigen and human platelet antigen antibodies in the setting of hematopoietic cell transplantation.

BACKGROUND AND OBJECTIVES: Antibodies (Ab) against HLA and HPA antigens play an important role in HCT. In this prospective study we evaluated prevalence and kinetics of HLA- and HPA-Ab after HCT, including a possible donor-recipient transfer and their clinical relevance in respect to platelet transfusion refractoriness (PTR). MATERIALS AND METHODS: Patients were consecutively recruited. Ab were determined by microbead assay technique and a mean fluorescence intensity cut-off of 1,000. RESULTS: At baseline, 21 donors (42 %) and 27 patients (54 %) had HLA-Ab with a mean panel reactivity (cPRA) of 34.9 ± 29.4 % and 46.1 ± 36.5 %, respectively. We observed a significant higher number of HLA-Ab specificities in female donors and patients and a predominance of HLA-class I Ab. At day 0 we detected an increase of HLA-Ab (from 526 to 673) and cPRA (55.2 ± 31.9 %). Thirty-six patients (72 %) developed new HLA-Ab, mainly 3 weeks after HCT. In 7 patients an HLA-Ab with the same specificity as detected in the corresponding donor emerged, suggesting a possible transfer from the donor to the recipient. Overall, MFI showed a high variation. Type and number of transfusions were not associated with number and intensity of HLA-Ab (ρ: -0.05 - 0.02). Number of HLA-Ab, cPRA and intensity were not associated with PTR, which occurred in 9 patients (18 %) and none had bleeding WHO > 2. CONCLUSIONS: Although a considerable number of patients have and develop HLA-Ab before and early after HCT, we found no association with PTR and bleeding and management should be individualized.

Prevention Admission into Nursing homes (PAN): study protocol for an explorative, prospective longitudinal pilot study.

BACKGROUND: In Switzerland, there is a lack of adequate rehabilitation services, and effective coordination, that take into account the multifactorial health risks of older people. The literature shows that the hospitalisation rate in rehabilitation facilities has increased in recent years and that a gender bias exists. Additionally, there is little or no evidence available on the effect that a post-acute care programme might have over an extended period on functioning, quality of life and the informal network of older people. Therefore, the aim of this trial is to evaluate the sustainability of post-acute care within three nursing homes in Zurich, Canton of Zurich, Switzerland. METHODS: The Prevention Admission into Nursing homes (PAN) study is a explorative, prospective, longitudinal pilot trial based on a convenience sample of three long-term care facilities in the Swiss Canton of Zurich. The proposed pilot study will examine the effects of a post-acute care programme on people aged ≥65 years with a post-acute care potential ≥ three admitted to any of the three post-acute care units (n = 260). Older people of all sexes admitted to one of the post-acute care units and likely to be discharged to home within 8 weeks will be eligible for participation in the study. The primary endpoint is functionality based on the Barthel Index. The secondary endpoints are independency based on delirium, cognition, mobility, falling concerns, frailty, weight/height/body mass index, post-acute care capability, quality of life, and lastly, the informal network. As part of process evaluation, a qualitative evaluation will be conducted based on constructive grounded theory to specifically analyse how the experience of informal caregivers (n = 30) can contribute to a successful daily life 6 months after discharge. DISCUSSION: We expect to observe improved functional status and independence after the post-acute care programme. The qualitative evaluation conducted with caregivers will complement our description of the transition of older people towards living at home. TRIAL REGISTRATION: This study is registered in the German Clinical Trials Register under DRKS00016647 (registered on 23.05.2019).

Pain Interventions for people with dementia: a quasi-experimental study.

BACKGROUND: Due to the complexity of the provision of care for people with dementia, pain assessment and management is still considered to be lacking. An optimal way to support frontline staff in providing pain assessment and management for people with dementia living in nursing homes has not yet been identified. The success of supporting interventions seems dependent on contextual factors in the nursing homes. This study, therefore, analyzes the feasibility of a nurse-led training intervention, using repeated on-site case studies, in modifying pain intensity and frequency in people with dementia. METHODS: Using a quasi-experimental design, we undertook a multi-center study of nurse-led training in pain management, with subsequent on-site case studies. Healthcare workers from 3 nursing homes assessed pain in 164 residents with dementia over 147 days. We used mixed-effect growth curve models with spline regression to analyze the data. RESULTS: We found that on-site case studies support frontline staff with pain management and assessment. Repeated reflection in case studies led to significantly longer pain free intervals (from 4.7 at baseline to 37.1 days at second follow-up) and decreased frequency of pain events (OR 0.54 at first follow-up and 0.43 at second follow-up). However no trends regarding pain intensity could be found. Therefore, on-site case studies may be valuable for improving pain frequency and pain-free intervals over time. CONCLUSION: This feasibility study shows the potential of on-site support for frontline nursing home staff. On-site case studies may also affect health outcomes in people with dementia. However, the complexity of dementia care necessitates the management of a broader range of needs. TRIAL REGISTRATION: The study was retrospectively registered on the tenth of January 2017 with the German registry of clinical trials (DRKS00009726).

No evidence for an effect of working from home on neck pain and neck disability among Swiss office workers: Short-term impact of COVID-19.

PURPOSE: The aim of this study was to investigate the effect of working from home on neck pain (NP) among office workers during the COVID-19 pandemic. METHODS: Participants from two Swiss organisations, aged 18-65 years and working from home during the lockdown (n = 69) were included. Baseline data collected in January 2020 before the lockdown (office work) were compared with follow-up data in April 2020 during lockdown (working from home). The primary outcome of NP was assessed with a measure of intensity and disability. Secondary outcomes were quality of workstation ergonomics, number of work breaks, and time spent working at the computer. Two linear mixed effects models were fitted to the data to estimate the change in NP. RESULTS: No clinically relevant change in the average NP intensity and neck disability was found between measurement time points. Each working hour at the computer increased NP intensity by 0.36 points (95% CI: 0.09 to 0.62) indicating strong evidence. No such effect was found for neck disability. Each work break taken reduced neck disability by 2.30 points (95% CI: - 4.18 to - 0.42, evidence). No such effect was found for NP intensity. There is very strong evidence that workstation ergonomics was poorer at home. CONCLUSION: The number of work breaks and hours spent at the computer seem to have a greater effect on NP than the place of work (office, at home), measurement time point (before COVID-19, during lockdown) or the workstation ergonomics. Further research should investigate the effect of social and psychological factors. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04169646.

Students' experience and adherence to containment measures during COVID-19 in Switzerland.

BACKGROUND: Young adults are not considered a risk group, but the public health response to COVID-19 impacts all citizens. We investigated the impact on young adults' and their adherence to containment measures addressing potential gender differences. METHODS: In April 2020 12 341 students of the Zurich University of Applied Sciences were invited to a longitudinal health survey. Survey topics spanned socio-demographic data, students' health status and behavior, COVID-19 specific impact, concerns, information sources, adherence to containment measures, and trust in government bodies. Group comparisons by gender and multivariate ordinal regression models assessing adherence to restrictions of mobility and social contacts were conducted (n = 2373). RESULTS: Mean age was 26.4 (SD = 5.6), 70% were female. 43.5% reported some concern about their own health, 2.7% stated major worries. Women experienced more conflicts (p < 0.000) and, enjoyed time with the family more (p < 0.000). Men felt less locked up (p = 0.001). The most frequented COVID-19 information source was public media (48%) and confidence in government bodies was high (82%) for both genders. Men yielded lower adjusted odds (OR; 95%-CI) of adherence regarding the following measures: social distancing (0.68; 0.53-0.87), non-utilization of public transport (0.74; 0.56-0.97), 5-person limit for social gatherings (0.47; 0.35-0.64) and the stay at home rule (0.64; 0.51-0.82). CONCLUSION: Early in the pandemic a high degree of adherence was observed in this young academic population. Containment measures restricting movement and social contact yielded considerable differences by gender, information source and perceived susceptibility to the virus. More targeted communication may increase adherence regarding mobility restrictions.

Improving caring quality for people with dementia in nursing homes using IPOS-Dem: A stepped-wedge cluster randomized controlled trial protocol.

AIMS: We aim to evaluate the effectiveness of the Integrated Palliative Care Outcome Scale for people with dementia-based case studies to improve the caring quality for people with dementia in nursing homes by frontline staff and family members. BACKGROUND: Swiss nursing homes mostly care for people with dementia. This population is at high risk of receiving little to no palliation for their complex needs. The majority of Swiss frontline healthcare staff do not systematically report on the needs of their residents. Additionally, family members do not routinely participate in assessment processes. DESIGN: We will conduct a stepped-wedge cluster randomized trial of repeated assessment using the Integrated Palliative Care Outcome Scale for people with dementia (IPOS-Dem) and subsequent case studies. Clusters will consist of Swiss nursing homes randomly assigned to one of three sequential intervention time points. METHODS: The study population will consist of people with dementia living in nursing homes with and without specialized dementia care facilities. Over 16 months, staff working at the frontline and family members will assess the needs and concerns of people with dementia using IPOS-Dem. Depending on sequence allocation, facilitated case studies will start after 3, 6 or 9 months. The primary outcome will be caring quality measured by QUALIDEM. The secondary outcome will be symptoms and concerns, as indicated by the IPOS-Dem sum-score. The Zürich Ethics Committee approved the study in 2019 (2019-01847). IMPACT: The results of this study will contribute to improving the effectiveness of person-centred care for people with dementia. Collaboration between healthcare staff and family members will be systematically developed and built upon thorough assessment using the IPOS-Dem and related case studies. The use of IPOS-Dem will offer all frontline staff a systematic approach to have an independent voice within the nursing process, regardless of their qualification or grade.

Long-Term Course of Haemoglobin and Ferritin Values in High-Frequency Donors of Whole Blood and Double Erythrocyte Apheresis.

BACKGROUND: High-intensity donation is a risk factor for iron deficiency in blood donors. Interdonation intervals for whole blood (WB) donation and double unit red blood cell apheresis (2RBC) vary among countries. We retrospectively evaluated the course of haemoglobin (Hb) and ferritin values in men regularly donating WB 4 times a year or 2RBC twice a year (i.e., maximal frequency) over a period of 48 months. METHODS: Data of male donors with 16 WB or 8 2RBC consecutive donations were analysed. The minimum Hb levels for WB donation and 2RBC apheresis (collection of 360 mL RBC) were 135 and 140 g/L, respectively. There was no lower limit set for ferritin, and no iron was substituted. RESULTS: We identified 294 WB (mean age 53 years, SD 11) and 151 2RBC donors (mean age 48 years, SD 9) who donated at a mean interval of 97 (SD 18) and 201 days (SD 32), respectively, between January 1, 2008, and December 31, 2013. At baseline, Hb and ferritin values were lower in WB donors compared to 2RBC donors, with a mean Hb of 153 g/L (SD 13) versus 159 g/L (SD 8) and a mean ferritin of 44 µg/L (SD 52) versus 73 µg/L (SD 56; p < 0.001 for both parameters), respectively. Ferritin was below 15 µg/L in 40 WB (14%) and in 4 (3%) 2RBC donors. In WB donors, the mean Hb levels at baseline versus last donation showed no significant difference (153 vs. 152 g/L, p = 0.068), whereas the mean ferritin levels decreased significantly (44 vs. 35 µg/L, p < 0.001). The 2RBC donor group displayed a statistically different decrease in both the mean Hb levels (158 vs. 157 g/L; p < 0.05) and the mean ferritin levels (73 vs. 66 µg/L; p = 0.052). The lowest Hb was measured at the 11th WB donation (152 g/L; p < 0.05) and at the 4th 2RBC apheresis (157 g/L; p < 0.05). There was no deferral due to low Hb at any time. The lowest ferritin was shown at the 4th WB (37 µg/L) and at the 3rd 2RBC donation (60 µg/L), respectively. At the last visit, ferritin was below 15 µg/L in 23 WB donors (8%) and in 2 2RBC donors (1%). CONCLUSIONS: High-intensity male donors with an interdonation interval of 12 weeks for WB donation and 24 weeks for 2RBC apheresis maintain acceptable Hb levels and, after an initial decline, stable ferritin levels despite ongoing blood donation.

On-site multi-component intervention to improve productivity and reduce the economic and personal burden of neck pain in Swiss office-workers (NEXpro): protocol for a cluster-randomized controlled trial.

BACKGROUND: Non-specific neck pain and headache are major economic and individual burden in office-workers. The aim of this study is to investigate the effect of a multi-component intervention combining workstation ergonomics, health promotion information group workshops, neck exercises, and an app to enhance intervention adherence to assess possible reductions in the economic and individual burden of prevalent and incident neck pain and headache in office workers. METHODS/DESIGN: This study is a stepped wedge cluster-randomized controlled trial. Eligible participants will be any office-worker aged 18-65 years from two Swiss organisations in the Cantons of Zurich and Aargau, working more than 25 h a week in predominantly sedentary office work and without serious health conditions of the neck. One hundred twenty voluntary participants will be assigned to 15 clusters which, at randomly selected time steps, switch from the control to the intervention group. The intervention will last 12 weeks and comprises workstation ergonomics, health promotion information group workshops, neck exercises and an adherence app. The primary outcome will be health-related productivity losses (presenteeism, absenteeism) using the Work Productivity and Activity Impairment Questionnaire. Secondary outcomes are neck disability and pain (measured by the Neck Disability Index, and muscle strength and endurance measures), headache (measured by the short-form headache impact test), psychosocial outcomes (e.g. job-stress index, Fear-Avoidance Beliefs Questionnaire), workplace outcomes (e.g. workstation ergonomics), adherence to intervention, and additional measures (e.g. care-seeking). Measurements will take place at baseline, 4 months, 8 months, and 12 months after commencement. Data will be analysed on an intention to treat basis and per protocol. Primary and secondary outcomes will be examined using linear mixed-effects models. DISCUSSION: To the authors' knowledge, this study is the first that investigates the impact of a multi-component intervention combining current evidence of effective interventions with an adherence app to assess the potential benefits on productivity, prevalent and incident neck pain, and headache. The outcomes will impact the individual, their workplace, as well as private and public policy by offering evidence for treatment and prevention of neck pain and headache in office-workers.

Association of functional status and hospital-acquired functional decline with 30-day outcomes in medical inpatients: A prospective cohort study.

BACKGROUND: There is growing evidence that patients with functional decline are at increased risk of readmission, mortality and institutionalization. Instruments to measure the status of self-care could provide important information for efficient care planning. The widely used Self Care Index serves as an indicator for the severity of nursing dependency. To date, no evidence is available on the association of the instrument with rehospitalization, mortality and institutionalization. OBJECTIVES: To examine the association of functional status measures (Self Care Index on admission, at discharge and functional decline) with 30-day mortality, readmission and institutionalization in hospitalized non-surgical patients. DESIGN: Prospective cohort study. PARTICIPANTS: We included 4540 emergency medical patients at a single hospital in Switzerland. METHODS: Primary outcome was 30-day mortality rate; secondary outcomes were 30-day readmission and institutionalization. We analyzed the association of the functional status with the binary endpoints using logistic regression models and C-statistics for discrimination. RESULTS: All of the examined measures were significant predictors of overall 30-day mortality; Self Care Index on admission: adj. OR: 0.90 (95% CI: 0.87-0.92); Self Care Index at discharge: adj. OR: 0.86 (95% CI: 0.83-0.88); functional decline: adj. OR: 1.22 (95% CI: 1.14-1.31) and all Self Care Index single items. A combined model (functional status on admission and functional decline during hospitalization) showed a good accuracy with regard to the AUC: adj. AUC: 0.80 (95% CI: 0.74-0.86). CONCLUSIONS: Several functional measures were associated with 30-day mortality. Self Care Index total score, five single items and a combined model showed the best performance.

Higher low back and neck pain in final year Swiss health professions' students: worrying susceptibilities identified in a multi-centre comparison to the national population.

BACKGROUND: Low back pain (LBP) and neck pain (NP) are of considerable socioeconomic burden. Considering the escalating demand on health services that LBP and NP have globally, they represent an arguably unsustainable drain on resources with the projected increased demand secondary to an ageing population. Identifying populations at risk for LBP and NP may inform public health prevention strategies. Health professions' (HP) students may be more susceptible due to their demographic factors and potentially risky postural demands of their education and formative clinical practice. The aim of our study was to compare self-reported LBP and NP of HP students with the general and stratified Swiss population to identify their prevalence. In addition, we compared the prevalence of LBP and NP in students studying different professions in order to identify whether susceptibilities exist. METHODS: In this cross-sectional study, self-reported LBP and NP reported by final-year HP students (n = 1848) were compared with the Swiss national population aged ≥15 years living in private households (n = 21,597). Binary regression models estimated crude prevalence and prevalence adjusted for age, gender, and education. Design-based F-Tests assessed differences between students and the Swiss population. RESULTS: Crude, overall four-week (4w) prevalence (mean (95% CIs)) for LBP was 61.0% (58.4-63.5) in all HP students versus 40.0% (39.2-40.9) in the Swiss population. Female HP students aged 21-30 years (63.3% (60.5-66.1)) reported higher LBP than the same-aged Swiss female population with secondary (43.7% (39.5-47.9)) or tertiary (36.6% (30.8-42.9)) education. Crude, overall 4w prevalence for NP was 59.8% (57.2-62.3) in all HP students versus 36.4% (35.6-37.3) in the Swiss population. Female health professions' students aged 21-30 years reported higher NP (63.2% (60.4-66.0)) than the same-aged Swiss female population with secondary (36.6% (32.7-40.8)) or tertiary (35.4% (29.6-41.8)) education. The inter-professional differences shown indicate midwifery to be most susceptible to reporting both conditions. CONCLUSIONS: Considerably higher LBP and NP were reported by final year HP students when compared with the general and stratified Swiss population. Worrying inter-professional susceptibilities were shown and reveal the need for further explanatory studies. Measures to reduce complex health problems like LBP and NP should be introduced into curricula in order to optimize the longevity of clinical careers and to protect the future HP workforce.

Change in fatty infiltration of lumbar multifidus, erector spinae, and psoas muscles in asymptomatic adults of Asian or Caucasian ethnicities.

PURPOSE: Fatty infiltration (FI) is a feature of degenerating muscle that predominates in the low lumbar spine, associates with pain, and is confounded by age, spinal degeneration, and curvature. We determined rates for decline of lumbar muscle quality according to ethnicity, muscle, and spinal level in asymptomatic subjects. METHODS: Cross-sectional simulation study assessing aggregated data; 650 Asians aged 20-89 years versus 80 Caucasians aged 20-62 years. Change in lumbar multifidus, erector spinae (ES), and psoas fat content were computed using synthetic data and Monte Carlo simulations. General linear regression models and multivariate adaptive regression splines enabled estimation of yearly decline rates [with 95% confidence intervals (CI)]. RESULTS: ES at L1-5 (total) shows steeply reduced density (rate; CI) for Asians in older (>53.3 years) adulthood (-0.32; -0.27 to -0.36/year). For Asians, multifidus (-0.18; -0.15 to -0.20/year) and psoas (-0.04; -0.03 to -0.06/year) also decline, while ES in younger ≤53.3 years) adults does not (0.06; 0.01-0.12/year). Caucasian multifidus declines (increasing FI % rate; CI) insignificantly faster (L1-5; 0.23; 0.10-0.36%/year) than ES (0.13; 0.04-0.22%/year). Multifidus decline does not differ between ethnicities. ES in older Asians generally declines fastest across ethnicities and muscles, and particularly in the low lumbar levels. Low lumbar levels show higher rates of decline in Asians, with mixed level-dependencies apparent in Caucasians. CONCLUSIONS: Decline in lumbar muscle composition may differ between ethnicities and muscles. ES and low lumbar levels appear increasingly susceptible in Asians. Longitudinal studies examining rate of change to muscle composition may provide distinction between spinal conditions.

Pain Intervention for people with Dementia in nursing homes (PID): study protocol for a quasi-experimental nurse intervention.

BACKGROUND: It is estimated that 19 to 83% of people with dementia suffer from pain that is inadequately treated in the last months of life. A large number of healthcare workers who care for these people in nursing homes lack appropriate expertise and may therefore not always recognise, assess and treat pain in those with dementia who have complex problems on time, properly and efficiently. The aim of this intervention trial is to identify care needs of people with dementia suffering from pain living in a nursing home. METHODS: A quasi-experimental nurse-led intervention trial based on a convenience sample of four nursing homes in the Swiss Canton of Zurich examines the effects on dementia patients (n = 411), the healthcare institution and the qualification level of the healthcare workers compared to historical controls, using an event analysis and a multilevel analysis. Healthcare workers will be individually trained how to assess, intervene and evaluate acute and chronic pain. There are three data-monitoring cycles (T0, T1, T2) and two intervention cycles (I1, I2) with a total study duration of 425 days. There is also a process evaluation based on Dobbins analyses that analyse in particular the potentials for change in clinical practice of change agents. DISCUSSION: The aim of the intervention trial is to improve pain management strategies in older people with dementia in nursing homes. Clinically significant findings will be expected that will help reduce suffering in the sense of "total pain" for people with dementia. The joint intra- and interdisciplinary collaboration between practice and supply-oriented (nursing) research will have both a lasting effect on the efficiency measurement and provide scientifically sound results. Nursing homes can integrate the findings from the intervention trial into their internal quality control process. The potential for improvements can be directly influenced by the nursing home itself.

Blood Group Distribution in Switzerland - a Historical Comparison.

BACKGROUND: Ethnicities differ in prevalence of blood groups and antigens. Substantial donor-recipient mismatch within mixed-ethnic societies may render certain recipients at higher risk for alloimmunization. Data regarding antigen distribution within Switzerland by ethnicity is limited. We examined immigration patterns against the distribution of ABO blood groups using large cross-sectional Swiss samples spanning 70 years. METHODS: Historical ABO blood group distribution data (1940-1945) from Swiss army personnel (n = 275,664) were sourced from the literature. Recent blood group phenotypes of 122,925 individuals who presented themselves at army recruitment centers (2004-2015) were obtained, alongside a validation sample of 175,202 patients from a university hospital. Two-sample tests with z-statistics assessing blood groups between samples were used. RESULTS: The respective proportions of A (47.2% and 45.2%), B (8.4% and 9.8%), and AB (3.0 and 4.1) in the historical and recent army samples were significantly different (p < 0.001), while group O was not. Conclusion: ABO blood groups in Switzerland have remained stable despite substantial immigration with a changing foreign-national profile. Further research is needed to improve the understanding of antigen differences in newly introduced ethnic groups. Blood product requirements and public health initiatives aimed at recruiting blood donors would benefit from this information.

Reliability of quantifying the spatial distribution of fatty infiltration in lumbar paravertebral muscles using a new segmentation method for T1-weighted MRI.

BACKGROUND: To our knowledge, there are no methods allowing for quantification of the spatial distribution of lumbar paravertebral muscle fatty infiltration (FI) in the transverse plane. There is an increasing emphasis on muscle tissues as modifiable factors in lumbar spine health. Population datasets based on conventional T1-weighted (T1-W) magnetic resonance imaging (MRI) represent a valuable resource for examining all spinal tissues, and methods with reliability are needed. The aim of our study was to determine the reliability of a novel method quantifying lumbar paravertebral muscle fat content based on conventional T1-W MRI. METHODS: Axial 3-Tesla T1W MRIs from ten adult subjects (3W, 7M; mean age 52.8 ± SD 7.2 years) were randomly selected from the large prospective cross-sectional Hong Kong Population-based Disc Degeneration Cohort study examining lumbar spine degeneration. The selected sample included subjects with mixed imaging-determined disc degeneration and low back pain history. Two raters with MRI lumbar paravertebral muscle analysis experience (R1 > 250 h and R2 > 1000 h) repeat-measured the image-set a week apart. Multifidus and erector spinae (spinalis, longissimus and iliocostalis) were manually outlined together on a single-slice from the inferior vertebral end-plates of L1 to L5 using a semi-automated, quartile-defining (Q1-4 (medial to lateral) and Qmean) MatLab-based programme. Bland-Altman plots and intra-class correlation coefficients (ICC) with 95 % confidence intervals (CI) describe intra- and inter-rater reliability according to lumbar level, quartile, and side, and combined level and quartile. RESULTS: There was good intra- (ICC = 0.88; CI: 0.87-0.90) and inter-rater agreement (ICC = 0.82; CI: 0.80-0.84). Intra-rater values for Qmean (ICC; CI) were higher at L5 (0.89; 0.79-0.94) than L1 (0.61; 0.37-0.78). Higher intra-rater values for L1-5 were shown at Q1 (0.93; 0.91-0.95) than Q3 (0.83; 0.78-0.87) or Q4 (0.81; 0.76-0.85), and on the right (0.91; 0.90-0.93) than left (0.85; 0.83-0.88). Similar observations were made for inter-rater values in terms of lumbar level and quartile, with no differences between sides shown. CONCLUSIONS: In our study of ten cases we demonstrate a reliable method to quantify the spatial distribution of fat content in lumbar paravertebral muscles based on T1W MRI. Understanding the geography of fat content in these muscles may offer additional insight in determining and improving spinal health. The clinical relevance and application of this method require testing across various populations to build on the early feasibility established in this study.
