To determine the frequency, timing, and duration of post-acute sequelae of SARS-CoV-2 infection (PASC) and their impact on health and function.
Post-acute sequelae of SARS-CoV-2 infection is an emerging major public health problem that is poorly understood and has no current treatment or cure. PASC is a new syndrome that has yet to be fully clinically characterised.
Descriptive cross-sectional survey (n = 5163) was conducted from online COVID-19 survivor support groups who reported symptoms for more than 21 days following SARS-CoV-2 infection.
Participants reported background demographics and the date and method of their covid diagnosis, as well as all symptoms experienced since onset of covid in terms of the symptom start date, duration, and Likert scales measuring three symptom-specific health impacts: pain and discomfort, work impairment, and social impairment. Descriptive statistics and measures of central tendencies were computed for participant demographics and symptom data.
Participants reported experiencing a mean of 21 symptoms (range 1–93); fatigue (79.0%), headache (55.3%), shortness of breath (55.3%) and difficulty concentrating (53.6%) were the most common. Symptoms often remitted and relapsed for extended periods of time (duration M = 112 days), longest lasting symptoms included the inability to exercise (M = 106.5 days), fatigue (M = 101.7 days) and difficulty concentrating, associated with memory impairment (M = 101.1 days). Participants reported extreme pressure at the base of the head, syncope, sharp or sudden chest pain, and “brain pressure” among the most distressing and impacting daily life.
Post-acute sequelae of SARS-CoV-2 infection can be characterised by a wide range of symptoms, many of which cause moderate-to-severe distress and can hinder survivors' overall well-being.
This study advances our understanding of the symptoms of PASC and their health impacts.
There is a need for novel approaches to address the complexity of social inequality in health. Public–private partnerships (PPPs) have been proposed as a promising approach; however, knowledge on lessons learnt from such partnerships remain unclear. This study synthesises evidence on opportunities and challenges of PPPs focusing on social inequality in health in upper-middle-income and high-income countries.
A systematic literature review and meta-synthesis was conducted using the Mixed Methods Appraisal Tool for quality appraisal.
PubMed, PsychInfo, Embase, Sociological Abstracts and SocIndex were searched for studies published between January 2013 and January 2023.
Studies were eligible if they applied a quantitative, qualitative, or mixed methods design and reported on lessons learnt from PPPs focusing on social inequality in health in upper-middle-income and high-income countries. Studies had to be published in either English, Danish, German, Norwegian or Swedish.
Two independent reviewers extracted data and appraised the quality of the included studies. A meta-synthesis with a descriptive intent was conducted and data were grouped into opportunities and challenges.
A total of 16 studies of varying methodological quality were included. Opportunities covered three themes: (1) creating synergies, (2) clear communication and coordination, and (3) trust to sustain partnerships. Challenges were identified as reflected in the following three themes: (1) scarce resources, (2) inadequate communication and coordination, and (3) concerns on distrust and conflicting interest.
Partnerships across public, private and academic institutions hold the potential to address social inequality in health. Nevertheless, a variety of important lessons learnt are identified in the scientific literature. For future PPPs to be successful, partners should be aware of the availability of resources, provide clear communication and coordination, and address concerns on distrust and conflicting interests among partners.

This study aims to evaluate the Language Access Systems Improvement (LASI) initiative’s impact on professional interpreter utilisation in primary care and to explore patient and clinician perspectives on professional interpreter use.
Multi methods: Quantitative natural experiment pre-LASI and post-LASI, qualitative semistructured interviews with clinicians and focus groups with patients post-LASI.
Large, academic primary care practice.
Cantonese, Mandarin, Spanish, English-speaking adult patients and their clinicians.
LASI initiative: Implementation of a clinician language proficiency test and simultaneous provision of on-demand access to professional interpreters via video medical interpretation.
Quantitative: Proportion of language discordant primary care visits which were professionally interpreted. Qualitative: Salient themes related to professional interpreter use and non-use.
The researchers categorised language concordance for 1475 visits with 152 unique clinicians; 698 were not fully language concordant (202 pre-LASI and 496 post-LASI). Professional interpreter utilisation increased (pre-LASI 57% vs post-LASI 66%; p=0.01); the visits with the lowest percentage of profssional interpreter use post-LASI were those in which clinicians and patients had partial language concordance. In inverse probability weighted analysis, restricting to 499 visits with strict estimated propensity score overlap (100% common support), post-LASI visits had higher odds of using a professional interpreter compared with pre-LASI visits (OR 2.39; 95% CI 1.04 to 5.48). Qualitative results demonstrate video interpretation was convenient and well liked by both clinicians and patients. Some partially bilingual clinicians reported frustration with patient refusal of interpreter services; others reported using the video interpreters as a backup during visits. Views of the care-partner role differed for clinicians and patients. Clinicians reported sometimes having family interpret out of convenience or habit, whereas patients reported wanting family members present for support and advocacy, not interpretation.
LASI increased utilisation of professional interpreters; however, this was least prominent for partially language concordant visits. Health systems wishing to implement LASI or similar interventions will need to support clinicians and patients with partial bilingual skills in their efforts to use professional interpreters.

Activist groups attack animal research and put scientists and their institutions under pressure, whereas scientists often remain silent. We report an interdisciplinary research project driven by a communication science perspective on how citizens respond to news reports about animal research (3 experiments, overall N = 765) and a German science-initiated information platform (“Tierversuche verstehen”; controlled user study, N = 100). Findings demonstrate that a critical journalist perspective within neutral, two-sided news reports (e.g., skeptical expert statements or images of suffering animals) does not affect citizen opinion strongly. Information media provided by scientific institutions seem to be welcomed even by citizens who hold critical prior attitudes. From these results, we develop a set of recommendations for future public communication of animal research that builds on best practices in organizational and crisis communication. These suggestions are intended to empower animal researchers to actively participate in public debate to support citizens’ informed attitude formation.Outcomes associated with rapid response teams (RRTs) are inconsistent. This may be due to underlying facilitators and barriers to RRT activation that are affected by team leaders and health systems.
The aim of this study was to synthesize the published research about facilitators and barriers to nurse-led RRT activation in the United States (U.S.).
A systematic review was conducted. Four databases were searched from January 2000 to June 2023 for peer-reviewed quantitative, qualitative, and mixed methods studies reporting facilitators and barriers to RRT activation. Studies conducted outside the U.S. or with physician-led teams were excluded.
Twenty-five studies met criteria representing 240,140 participants that included clinicians and hospitalized adults. Three domains of facilitators and barriers to RRT activation were identified: (1) hospital infrastructure, (2) clinician culture, and (3) nurses' beliefs, attributes, and knowledge. Categories were identified within each domain. The categories of perceived benefits and positive beliefs about RRTs, knowing when to activate the RRT, and hospital-wide policies and practices most facilitated activation, whereas the categories of negative perceptions and concerns about RRTs and uncertainties surrounding RRT activation were the dominant barriers.
Facilitators and barriers to RRT activation were interrelated. Some facilitators like hospital leader and physician support of RRTs became barriers when absent. Intradisciplinary communication and collaboration between nurses can positively and negatively impact RRT activation. The expertise of RRT nurses should be further studied.
Incidents of maternal morbidity and mortality (MMM) continue to rise in the USA. Significant racial and ethnic health inequities exist, with Native American (NA) women being three to four times more likely to die than white, non-Hispanic women, and three to five times more likely to experience an incident of severe maternal morbidity. Few studies have identified individual and community-level risk factors of MMM experienced by NA women. Therefore, this systematic review will identify said risk factors of MMM experienced by NA women in the USA.
This systematic review will be conducted according to the Cochrane Handbook for Systematic Reviews, and the findings will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA). The search strategy will include searches from electronic databases: PUBMED, EMBASE, CINAHL and SCOPUS, from 1 January 2012 to 10 October 2022. The search strategy will include terms related to the search concepts: ‘maternal’, ‘Native American’ and ‘MMM’. Bibliographies of selected articles, previously published reviews and high-yield journals will also be searched. All included papers will be evaluated for quality and bias using NIH Quality Assessment Tools for Observational Studies. A description of the study findings will be presented in a tabular format organised by outcome of interest along with study characteristics.
There are no formal ethics approvals needed for this protocol. The findings of this systematic review will be shared with academic, governmental, community-based, institutes and NA (tribal) entities via a published peer-reviewed article, informational brief, poster and oral presentations.

Central retinal artery occlusion (CRAO; retinal stroke or eye stroke) is an under-recognized, disabling form of acute ischemic stroke which causes severe visual loss in one eye. The classical risk factor for CRAO is ipsilateral carotid stenosis; however, nearly half of patients with CRAO do not have high-grade carotid stenosis, suggesting that other cardiovascular risk factors may exist for CRAO. Specifically, prior studies have suggested that cardioembolism, driven by underlying atrial fibrillation, may predispose patients to CRAO. We describe the design of an observational, population-based study in this protocol. We evaluate two specific objectives: 1) To determine if atrial fibrillation is an independent risk factor for CRAO after adjusting for medical and cardiovascular risk; 2) To determine if use of oral anticoagulation can modify the risk of CRAO for patients with atrial fibrillation. This protocol lays out our strategy for cohort definition, case and control definition, comorbidity ascertainment, and statistical methods.Fear of fall is experienced by the elderly irrespective of the presence or absence of history of fall. Falls contribute to injuries that culminate in hospitalisation that incur unwarranted medical expenses. Yoga is unique to Indian cultural practices, with a potential to enhance proprioception. It increases self-body awareness, ultimately improving the balancing capacity of older adults. Thus, the objective of this study is to compare the effect of yoga therapy in the study and control groups at 12 weeks from the baseline.
This study is designed as an open-label, randomised controlled trial (1:1) with a sample size of 62 elderly patients more than or equal to 60 years of age. Participation of either sex, male or female with a fear of fall will be considered. Two randomised groups of 31 participants each will receive standard therapy for their primary diseases as per the local, national or international guidelines. However, participants in the intervention arm will receive additional structured yoga therapy sessions. The primary objective of this study is to assess and compare the change in fear of fall score of participants in each group using Falls Efficacy Scale (FES) and Berg Balance Scale (BBS) at 12 weeks versus baseline. The secondary endpoint will assess the change in the quality of life of participants at 3 months compared with the baseline.
Data will be gathered, entered into Microsoft Excel and further analysed by R software (V.4.3.0). Changes in FES-Intervention and BBS of two groups will be compared either by Student’s t-test for parametric data or Mann-Whitney U test for non-parametric data. Statistical significance will be considered if p

Understanding how different Black and other racially minoritised communities thrive is an emerging priority area in mental health promotion. Literature demonstrates health benefits of social capital (social resources embedded within social networks). However, its effects are not always positive, particularly for certain subpopulations who are already disadvantaged.The CONtributions of social NEtworks to Community Thriving (CONNECT) study will use Participatory Action Research (PAR) to investigate social capital as a resource that benefits (or hinders) racially minoritised communities and their mental health. The CONNECT study was designed within a partnership with community organisations and responds to local policy in two South-East London Boroughs, thereby providing potential channels for the action component of PAR. Taking an anti-racism lens, we acknowledge the underpinning role of racism in creating health inequities. We apply an intersectional framework to be considerate of overlapping forms of oppression such as age, gender, socioeconomic status, and sexual orientation as an essential part of developing effective strategies to tackle health inequities. Key components of this mixed methods PAR study include (1) involving racialised minority community members as peer researchers in the team (2) collecting and analysing primary qualitative data via interviews, photovoice, and community mapping workshops, (3) developing relevant research questions guided by peer researchers and collaborating organisations and analysing secondary quantitative data accordingly, (4) integrating qualitative and quantitative phases, and (5) working closely with community and policy partners to act on our findings and use our research for social change.The PAR approach will allow us to engage community (voluntary sector and government) and academic partners in decision making and help address imbalances in power and resource allocation. Knowledge generated through this collaborative approach will contribute to existing community initiatives, policies, and council strategies. This will ensure the views and experiences of racially minoritised communities drive the changes we are collaboratively committed to achieving.by David Röthlisberger, Katharina Tabea Jungo, Lukas Bütikofer, Rosalinde K.

BackgroundFalls and consequent injuries are prevalent in older adults. In this group, half of injury-related hospitalizations are associated with falls and the rate of falls increases with age. The evidence on the role of blood pressure and the use of antihypertensive treatment on the risk of falls remains unclear in oldest-old adults (≥85 years).
ObjectivesTo examine the association between systolic blood pressure (SBP) and incident falls with medical consequences in oldest-old adults and to analyse whether this association is modified by the use of antihypertensive treatments or the presence of cardiovascular disease.
MethodsWe analysed data from the Leiden 85-plus Study, a prospective, population-based cohort study with adults aged ≥85 years and a 5-year follow-up. Falls with medical consequences were reported by the treating physician of participants. We assessed the association between time-updated systolic blood pressure and the risk of falling over a follow-up period of five years using generalized linear mixed effects models with a binomial distribution and a logit link function. Subgroup analyses were performed to examine the role of antihypertensive treatment and the difference between participant with and without cardiovascular disease.
ResultsWe analysed data from 544 oldest-old adults, 242 (44.4%) of which used antihypertensives. In 81 individuals (15%) ≥1 fall(s) were reported during the follow-up period. The odds for a fall decreased by a factor of 0.86 (95% CI 0.80 to 0.93) for each increase in blood pressure by 10 mmHg. This effect was specific to blood pressure values above 130mmHg. We did not find any evidence that the effect would be modified by antihypertensive treatment, but that there was a tendency that it would be weaker in participants with cardiovascular disease (OR 0.81, 95% CI 0.72 to 0.90 per 10mmHg) compared to those without cardiovascular disease (OR 0.94, 95% CI 0.84 to 1.05 per 10mmHg).
ConclusionOur results point towards a possible benefit of higher blood pressure in the oldest-old with respect to falls independent of the use of antihypertensive treatments.
Knife-enabled crime is a UK public health issue leading to substantial impacts on society, victims and their families, as well as additional strain on the healthcare system. Despite the increase in knife-enabled crime and the overwhelming consequences, there is a lack of comprehensive studies exploring the long-term health outcomes of knife crime victims in the UK. The research gap hinders the development of more targeted secondary preventative interventions, resource allocation and public awareness campaigns. This systematic review aims to identify the long-term health outcomes of knife crime victims, therefore providing valuable knowledge for stakeholders, health practitioners and policymakers for a more effective public health response.
A comprehensive search strategy was developed, focusing on four key concepts: study design, knife-related offences, outcomes and risk. Databases being searched include MEDLINE, EMBASE, PsycINFO, ProQuest Criminology Collection, Web of Science Core Collection, Google Scholar and OpenGrey. Reference lists and forward citations will be inspected for further suitable literature. The study selection will involve two independent reviewers screening the studies from the search, with disagreements resolved by a third reviewer. All UK quantitative research on long-term health outcomes of knife crime victims will be included in the review. Covidence will be used to efficiently manage data. A data extraction form has been developed which will summarise key aspects of each study that will be included in the review. Methodological Index for Non-Randomised Studies quality assessment checklist will be used to assess the studies and the Newcastle-Ottawa Scale will assess the risk of bias in each study. Findings will be narratively synthesised, and if heterogeneity is sufficient, a meta-analysis will be conducted.
Ethics approval is not required for this study as no original data will be collected. The results will be disseminated through a peer-reviewed publication and conference presentation.
To assess French nursing home nurses' opinions on the potential evolution of their antibiotic stewardship role, facilitators and barriers, and nurses' characteristics associated with their opinion toward new roles regarding antibiotic prescribing.
We conducted a cross-sectional study in French nursing homes with ≥20 beds and for which an email address was available in a national database managed by the French government between May and June 2022.
A self-administered internet-based questionnaire of 43 closed-ended Likert items was sent to directors of eligible nursing homes by email asking them to forward the link to the questionnaire to the nurses and head nurses of their institution. Data analysis included descriptive statistics and χ2 tests.
7215 nursing homes were sent the online questionnaire; 1090 participants completed it partially or totally and 923 fully filled in the questionnaire. A majority of nurses supported strengthening and expanding their antibiotic stewardship role. Regarding new roles, over 70% agreed that nurses could collect urine samples to perform a urine culture on their own initiative, prescribe microbiological laboratory tests, and change the drug formulation or the administration route of the antibiotic prescribed by the general practitioner.
One-third declared that they could initiate antibiotics for some infections and/or change the empirical antibiotic treatment prescribed by the general practitioner. Nurses from public nursing homes with connection to a hospital (27.5% vs. >35% for other status) and with recent experience in nursing homes (31% for <5 years of practice vs. 41% for 10 years or more) were less likely to agree to prescribe antibiotics.
This quantitative questionnaire survey identified potential new nurses' roles in antibiotic stewardship that seem to be acceptable and feasible for participants. These new nurses' roles need to be explored in future experimentations before considering implementation.
The study adhered to relevant EQUATOR guidelines and followed the STROBE reporting guidelines.
A self-administered internet-based questionnaire was sent to directors of eligible nursing homes by email asking them to forward the link to the questionnaire to the nurses and head nurses of their institution. Nurses and head nurses who were interested and willing could complete the questionnaire online partially or fully.
This study is not a clinical trial and is not eligible for trial registration. We used another suitable study registration site, the Center for Open Science.
Hormone therapy (HT) is a major adjuvant treatment for breast cancer. Despite their effectiveness, aromatase inhibitors can cause several side effects, including arthralgia in 35%–50% of patients. These side effects frequently lead to the premature discontinuation of HT. Whole-body cryotherapy (WBC) can be used for managing arthritic pain. The primary objective of this study will be to evaluate the effect of WBC on aromatase-induced joint pain, compared with placebo cryotherapy, in patients with hormone-dependent breast cancer receiving adjuvant aromatase inhibitors. The secondary objectives will be to evaluate WBC safety and its effect on analgesic consumption, HT adherence and quality of life.
In this randomised, placebo-controlled, double-blinded clinical trial, 56 patients with aromatase inhibitor-induced joint pain and a Brief Pain Inventory-Short Form (BPI-SF) score ≥3 for the worst pain experienced in the previous week will be randomised into the WBC or placebo cryotherapy arm (10 sessions in each group). The primary outcome will be the BPI-SF score at week 6 post-treatment. The secondary outcomes will include the BPI-SF scores at months 3 and 6 post-treatment, the BPI-SF pain severity index and pain interference index, the Health Assessment Questionnaire score, the number of days of aromatase inhibitor treatment and analgesic consumption in the 15 days before the visits at week 6 and months 3 and 6 after cryotherapy. The incidence of adverse events will also be investigated.
Ethics approval was obtained from the Ethics Committee Est IV of Hospital Civil, Strasbourg, France. Protocol V.5 was approved in December 2022. The results will be disseminated in a peer-reviewed journal and presented at international congresses.

PurposeTo evaluate the laser power stability of the SubCyclo probe for micropulse transscleral cyclophotocoagulation after repeated use.
Materials and methodsThis experimental study involved 6 new probes. Each probe was connected to the SubCyclo mode (2,000 mW power, 31.3% duty cycle, and 100 seconds duration) of the Vitra 810 laser delivery system (Quantel Medical, France). Laser power measurements were taken using a calibrated laser power meter (Nova, Ophir Optronics Solutions, Israel) every 10 seconds from 10 to 90 seconds during each of the 40 cycles. Intra-rater reliability was assessed using intraclass correlation (ICC). A linear mixed model for repeated measures and pairwise comparisons with Bonferroni adjustment were used for the analysis.
ResultsThe mean (SD) power outputs of all probes for the first cycle and all cycles were 421.9 (19.7) mW and 436.7 (16.1) mW, respectively. During the first cycle, the mean (SD) laser power gradually decreased from 444.3 (13.4) mW at 10 seconds to 407.3 (17.0) mW at 90 seconds (Fig 3). For all cycles, the power was 446.0 (13.6) mW at 10 seconds and gradually declined to 426.8 (21.0) mW at 90 seconds. Pairwise comparisons revealed significant differences in mean laser power outputs after 16 cycles of repeated use compared to the first cycle. The ICC estimate (95% CI) for intra-rater reliability was 0.96 (0.89, 0.99).
ConclusionsThe SubCyclo probe maintains stable laser power outputs throughout repeated use for up to 16 cycles, with a significant increase observed after 16 cycles.
To explore nurses' experiences of providing support to South Asian (SA) people with dementia and their family carers and to identify barriers and enablers of good transcultural care.
A qualitative, phenomenological design was used.
Fifteen registered community and in-patient nurses were recruited via one NHS Mental Health Foundation Trust. Nurses were from diverse backgrounds (Black, Ghanaian, Irish, Mauritian and White), 13 females and 2 males, and had been qualified from between 2 and 49 years. One-to-one semi-structured interviews were conducted between July and October 2019.
A thematic analysis identified three themes. ‘Communication challenges’ highlighted the impact of language barriers and the consequences of misunderstandings due to a dissonance in cultural values between nurses and interpreters. ‘The bi-directional impact of culture’ identified the two-way dynamics of transcultural work, the process of countering mutual stigma, and revealed an original perspective on how ‘cultural desire’ grows through practice experiences rather than being a prior motivation for learning. ‘Learning experiences’ showed that most learning was informal, experiential and prolonged, with nurses feeling they had unmet learning needs.
Nurses have minimal training opportunities and are under-supported in their transcultural work, potentially perpetuating the disadvantages that SA people with dementia and their families face in relation to healthcare. Enhanced cultural understanding of self and others and application of specific communication strategies could support nurses, together with interpreters, to build rapport and effective working relationships with each other and service users.
Transcultural nursing is a key competency, but nurses experience difficulties with providing care which is recognized as effective by SA family carers. The development of more acceptable and effective services requires improved mutual cultural understanding between nurses, interpreters and families, underpinned by joint brief training interventions, leading to more effective professional communication, better care outcomes and improved satisfaction with services.

Stable isotope analysis is a powerful tool for dietary modeling and trophic ecology research. A crucial piece of information for isotopic dietary modeling is the accurate estimation of trophic discrimination factors (TDFs), or the isotopic offset between a consumer’s tissue and its diet. In order to parameterize stable isotope dietary models for future climate scenarios, we investigated the effect of water temperature and dietary protein and lipid content on TDFs in juvenile Pacific cod (Gadus macrocephalus). Pacific cod are a commercially and ecologically important species, with stock numbers in the northeast Pacific recently having dropped by more than 70%. We tested four water temperatures (6, 8, 10, and 12°C) and two dietary regimens (low and high lipid content), representing a range of potential ocean temperature and prey quality scenarios, in order to determine carbon and nitrogen TDFs in juvenile Pacific cod. Additionally, we assessed dietary intake and proximate composition of the experimental fish in order to estimate consumption, assimilation, and retention of dietary nutrients. The results of this study suggest that dietary protein catabolism is a primary driver of nitrogen TDF variability in juvenile Pacific cod. Across all temperature treatments from 6 to 12°C, fish reared on the lower quality, lower lipid content diet had higher nitrogen TDFs. The mean TDFs for fish raised on the higher lipid, lower protein diet were +3.40 ‰ for nitrogen (Δ15N) and +0.36 ‰ for lipid-corrected carbon (Δ LC 13C). The mean TDFs for fish raised on the lower lipid, higher protein diet were +4.09 ‰ for nitrogen (Δ15N) and 0.00 ‰ for lipid-corrected carbon (Δ LC 13C). Lipid-corrected carbon isotope data showed that, regardless of temperature, fish consuming the lower lipid diet had essentially no trophic discrimination between diet and bulk tissues. We found no ecologically meaningful differences in TDFs due to water temperature across the 6°experimental range. The results of this experiment demonstrate that dietary quality, and more specifically the use of dietary protein for energetic needs, is a primary driver of trophic discrimination factors. The TDFs determined in this study can be applied to understanding trophic ecology in Pacific cod and closely related species under rapidly changing prey availability and ocean temperature conditions.by Daniel König, Patrick Jendricke, Katharina Poggel, Lena Staab, Albert Gollhofer
Today, university students face study conditions that increase the risk of sedentary behavior, unhealthy eating, and the likelihood of stress, anxiety, and depression. Although the situation has likely worsened in recent months due to the COVID-19 pandemic, even in the pre-Corona era, several investigations have demonstrated that the students’ health behaviors could increase the incidence of metabolic risk factors and non-communicable diseases, however, further and detailed information is needed to develop tailored counter-strategies. Therefore, in the present survey, the current health status of students at the Albert-Ludwigs-Universität Freiburg (ALU) will be recorded by various questionnaires. In addition, barriers that could potentially influence their health behavior will be identified, and information on the use and awareness of existing health services will be obtained in order to derive concrete needs for further health promotion activities. The study is designed as a monocentric and prospective study at the ALU; the survey of students’ situation and needs assessments will be conducted in the areas of nutrition, exercise, relaxation and stress reduction, self-management, psychosocial health and socio-demographic correlations via an anonymous and self-administered online questionnaire. Subsequently in two-year intervals, the survey will be repeated. Data will be collected over a period of 4 years. One goal of this survey is to gain more insight into the health situation of university students; another goal is to use the knowledge gained to integrate holistic health measures into the university landscape in a structured and sustainable manner. These health measures will be implemented by using the newly developed student health care management at the ALU (www.sgm.uni-freiburg.de). Every two years, after evaluation of the surveys, the effect of the health measures can be checked and adjusted. Trial registration: ETK: 20–1082; DRKS-ID: DRKS00024088.by Matthew L.

Mobile crisis services for people experiencing distress related to mental health or substance use are expanding rapidly across the US, yet there is little evidence to support these specific models of care. These new programs present a unique opportunity to expand the literature by utilizing implementation science methods to inform the future design of crisis systems. This mixed methods study will examine the effectiveness and acceptability of the Street Crisis Response Team (SCRT), a new 911-dispatched multidisciplinary mobile crisis intervention piloted in San Francisco, California. First, using quantitative data from electronic health records, we will conduct an interrupted time series analysis to quantitatively examine the impacts of the SCRT on people experiencing homelessness who utilized public behavioral health crisis services in San Francisco between November 2019 and August 2022, across four main outcomes within 30 days of the crisis episode: routine care utilization, crisis care reutilization, assessment for housing services, and jail entry. Second, to understand its impact on health equity, we will analyze racial and ethnic disparities in these outcomes prior to and after implementation of the SCRT. For the qualitative component, we will conduct semi-structured interviews with recipients of the SCRT’s services to understand their experiences of the intervention and to identify how the SCRT influenced their health-related trajectories after the crisis encounter. Once complete, the quantitative and qualitative findings will be further analyzed in tandem to assist with more nuanced understanding of the effectiveness of the SCRT program. This evaluation of a novel mobile crisis response program will advance the field, while also providing a model for how real-world program implementation can be achieved in crisis service settings.by Joseph B.

ObjectivesThe purpose of this study was to compare the rates of secondary knee surgery for patients undergoing meniscus repair with or without concurrent anterior cruciate ligament reconstruction (ACLr).
MethodsUtilizing a large national database, patients with meniscal repair with or without concurrent arthroscopic ACLr were identified. The two cohorts were then queried for secondary surgical procedures of the knee within the following 2 years. Frequency, age distribution, rates of secondary surgery, and type of secondary procedures performed were compared.
ResultsIn total, 1,585 patients were identified: meniscus repair with ACLr was performed for 1,006 (63.5%) and isolated meniscal repair was performed for 579 (36.5%). Minimum of two year follow up was present for 487 (30.7% of the overall study population).Secondary surgery rates were not significantly different between meniscus repair with concurrent ACLr and isolated meniscus repairs with an overall mean follow up of 13 years (1.5–24 years) (10.6% vs. 13.6%, p = 0.126). For the 2 year follow up cohort, secondary surgery rates were not significantly different (19.3% vs. 25.6%, p = 0.1098). There were no differences in survivorship patterns between the two procedures, both in the larger cohort (p = 0.2016), and the cohort with minimum 2-year follow-up (p = 0.0586).
ConclusionThe current study assessed secondary surgery rates in patients undergoing meniscus repair with or without concurrent ACLr in a large patient database. Based on this data, no significant difference in rates of secondary knee surgery was identified.

BackgroundTimely referral for advanced therapies (i.e., heart transplantation, left ventricular assist device) is critical for ensuring optimal outcomes for heart failure patients. Using electronic health records, our goal was to use data from a single hospitalization to develop an interpretable clinical decision-making system for predicting the need for advanced therapies at the subsequent hospitalization.
MethodsMichigan Medicine heart failure patients from 2013–2021 with a left ventricular ejection fraction ≤ 35% and at least two heart failure hospitalizations within one year were used to train an interpretable machine learning model constructed using fuzzy logic and tropical geometry. Clinical knowledge was used to initialize the model. The performance and robustness of the model were evaluated with the mean and standard deviation of the area under the receiver operating curve (AUC), the area under the precision-recall curve (AUPRC), and the F1 score of the ensemble. We inferred membership functions from the model for continuous clinical variables, extracted decision rules, and then evaluated their relative importance.
ResultsThe model was trained and validated using data from 557 heart failure hospitalizations from 300 patients, of whom 193 received advanced therapies. The mean (standard deviation) of AUC, AUPRC, and F1 scores of the proposed model initialized with clinical knowledge was 0.747 (0.080), 0.642 (0.080), and 0.569 (0.067), respectively, showing superior predictive performance or increased interpretability over other machine learning methods. The model learned critical risk factors predicting the need for advanced therapies in the subsequent hospitalization. Furthermore, our model displayed transparent rule sets composed of these critical concepts to justify the prediction.
ConclusionThese results demonstrate the ability to successfully predict the need for advanced heart failure therapies by generating transparent and accessible clinical rules although further research is needed to prospectively validate the risk factors identified by the model.
