A false-positive hepatitis serology result may not be solely due to intravenous immunoglobulins (IVIG) administration but may also result from cross-reacting antibodies from other infections, autoimmune diseases, recent hepatitis B vaccination, or interactions with rheumatoid factor or biotin. Furthermore, technical errors, such as faulty reagents or unsuitable testing methods, as well as certain patient groups, for example, those with certain chronic diseases, can also contribute to false-positive results. More likely than interference from IVIGs, the false-positive hepatitis serology result in one of the studies we read is due to Henoch-Schönlein pupura.
Empirical data support the use of N-terminal pro-B-type brain natriuretic peptide (NT-proBNP) for heart failure (HF) rule-in and rule-out in patients with acquired heart disease, but similar data are lacking in adults with congenital heart disease (CHD). The purpose of this study was to assess diagnostic performance of conventional NT-proBNP cutoff points for HF diagnosis (rule-in and rule-out) in adults with CHD. Retrospective study of adults with CHD and NT-proBNP measurement in the outpatient clinic (outpatient cohort) or in the emergency department (ED) (2003-2023). HF diagnosis was based on clinical assessment at the time of NT-proBNP measurement. Logistic regression was used to assess the diagnostic performance of conventional NT-proBNP cutoff points (<125 pg/ml for HF rule-out and ≥250 pg/ml for HF rule-in in the outpatient setting; <300 pg/ml for HF rule-out and ≥450 pg/ml for HF rule-in in the ED setting). The outpatient cohort comprised 3961 patients (age 45 ± 16 years), and NT-proBNP <125 pg/ml ruled-out HF with 86% sensitivity, while NT-proBNP level ≥250 pg/ml ruled-in with 68% specificity. The ED cohort comprised 687 patients (age 49 ± 16 years) and NT-proBNP level <300 pg/ml ruled-out HF with 82% sensitivity, and NT-proBNP level ≥450 pg/ml ruled-in HF with 75% specificity. These data support the use of these NT-proBNP levels for HF screening in the CHD population, which in turn would enable early detection and treatment of HF.
Adult T-cell leukemia/lymphoma (ATLL) is a rare, human T-lymphotropic virus type 1 (HTLV-1)-driven neoplasm that is often underrecognized in low-endemic regions. We describe a 23-year-old man with an eight-year history of chronic dry cough who later developed weight loss, night sweats, odynophagia, and dyspnea. CT revealed cervical/supraclavicular lymphadenopathy with innumerable pulmonary micronodules, interlobular septal thickening, and ground-glass opacities; abdominal imaging showed hepatosplenomegaly, ascites, and extensive retroperitoneal/mesenteric adenopathy. HTLV-1 ELISA and confirmatory Western blot were positive. Excisional lymph node biopsy demonstrated diffuse architectural effacement by atypical T cells with a CD3+, CD4+, CD5+, CD25+, CD7-, granzyme B+ immunophenotype and a ~90% Ki-67 index, establishing lymphomatous-type ATLL with a cytotoxic profile. Despite rapid recognition, the patient deteriorated and died from respiratory failure 15 days after diagnosis, before chemotherapy could begin. This lung-predominant presentation in a young adult illustrates how ATLL can mimic chronic pulmonary disease and evade early detection outside endemic areas. Clinicians should prioritize early tissue acquisition and a minimal T-cell panel (CD3, CD4, CD25, CD7, Ki-67); a CD4+CD25+ phenotype with CD7 loss should prompt HTLV-1 testing irrespective of geography. Streamlined access to immunophenotyping and confirmatory HTLV-1 assays is essential to reduce diagnostic delays and improve outcomes. When a long-lasting cough hid a rare blood cancer in a young adult This report describes a 23-year-old man who had a dry cough for eight years. Over time he also developed weight loss, night sweats, trouble swallowing, and shortness of breath. Scans showed enlarged lymph nodes in the neck and abdomen and many small spots in the lungs. Common infections were ruled out. A surgical sample of a swollen lymph node confirmed a rare blood cancer called adult T-cell leukemia/lymphoma (ATLL). ATLL is caused by infection with a virus named human T-lymphotropic virus type 1 (HTLV-1). The virus is common in some parts of the world but uncommon in many others. Because of this, doctors outside high-risk regions may not think of ATLL right away—especially when symptoms seem to come from the lungs and blood tests are not striking. This can delay diagnosis. Our case shows that ATLL can look like a chronic lung disease for years, even in a young person. We highlight a practical approach that may speed up care in low- and middle-income settings: (1) consider ATLL when long-lasting cough is accompanied by weight loss, night sweats, or swollen lymph nodes; (2) obtain a tissue sample early; and (3) request HTLV-1 testing when suspicion is raised. Clear referral pathways to outside laboratories can help when advanced tests are not available locally. Despite recognition after the biopsy, our patient’s breathing worsened rapidly and he died before treatment could begin. Raising awareness of this unusual presentation may help clinicians reach the diagnosis sooner and improve patient outcomes.
Background: We evaluated whether adding S100B to NSE improved discrimination or high-specificity rule-in of poor neurological outcome after out-of-hospital cardiac arrest (OHCA). Methods: In this single-center retrospective cohort study, comatose adult OHCA survivors treated with targeted temperature management had NSE and S100B measured at 0, 24, 48, and 72 h after return of spontaneous circulation. At each time point, we assessed NSE alone, S100B alone, and a logistic model combining both biomarkers in paired complete cases. Discrimination was assessed using the area under the receiver operating characteristic curve (AUC). Rule-in performance was evaluated using a timepoint-specific threshold that achieved 100% specificity in our cohort. Poor neurological outcome was defined as cerebral performance category 3-5 at 6 months. Results: Among 124 patients, 66 (53.2%) had poor outcomes. AUCs were similar between NSE alone and the combination across all time points (all p > 0.3). At 48 h, the combination ruled in 46/65 (70.8%) patients with poor outcome versus 36/65 (55.4%) with NSE alone, identifying 10 additional patients and a 15.4-percentage-point difference (95% confidence interval, -5.6 to 23.6). Conclusions: Adding S100B to NSE did not improve overall discrimination. The higher 48 h rule-in yield was estimated imprecisely and should be interpreted cautiously. Our findings require external validation before they can be translated to clinical settings.
Hiccups are commonly benign, self-limiting events often triggered by transient gastrointestinal or central nervous system irritants. However, when persistent, they may indicate underlying pathology involving the thoracic, gastrointestinal, or neurological systems. We report the case of a 65-year-old male smoker who presented with a 4-day history of persistent hiccups. He denied fever, chest pain, hemoptysis, or other systemic symptoms. Physical examination was largely unremarkable except for decreased air entry in the right middle and lower lung zones. Initial investigations, including gastroscopy and tumor markers, ruled out gastrointestinal causes. CT scan of the chest revealed a right lower lobe consolidation and cavitation with air fluid level and adjacent ground-glass opacities, along with enlarged subcarinal lymph nodes. Differential diagnoses included lung abscess, pneumonia, and tuberculosis cavitation. The patient was admitted for suspected lung abscess and received antibiotics. Bronchoscopy with bronchoalveolar lavage revealed no endobronchial lesions, and PCR testing and culture of the fluid was negative for tuberculosis but positive for klebsiella pneumonia. Despite radiologic regression of pneumonia, the cavitary lesion and lymphadenopathy persisted initially, but later started to regress. This case highlights an unusual presentation of lung abscess manifesting solely as persistent hiccups, without classic respiratory or systemic signs. We aim to emphasize the need to consider thoracic causes in patients with otherwise unexplained persistent hiccups, and undergo further evaluation in such cases.
Epstein-Barr virus (EBV) typically causes infectious mononucleosis, but in rare cases, it may lead to complications such as autoimmune hemolytic anemia (AIHA) and hepatitis. We report the case of an 18-year-old previously healthy female who presented with jaundice, red urine, and arthralgia. Laboratory workup revealed direct hyperbilirubinemia, elevated transaminases, and a direct antiglobulin test positive for IgG (negative for C3d), consistent with warm autoimmune hemolytic anemia in the context of EBV infection. Imaging ruled out biliary obstruction. The patient was managed conservatively, with cautious steroid use, and demonstrated clinical improvement without progression to hepatic failure. This case underscores the importance of recognizing atypical hepatic presentations of EBV and carefully managing overlapping autoimmune complications.
Online antenatal education is increasingly used to improve maternal psychological outcomes and preparedness for childbirth. However, evidence regarding its effectiveness remains inconsistent, particularly due to heterogeneity in intervention types and outcome measures. This systematic review and meta-analysis was conducted in accordance with PRISMA 2020 guidelines. PubMed, EMBASE, Scopus, Web of Science, CINAHL, and the Cochrane Library were searched from inception to March 2026. Randomized controlled trials and observational studies evaluating digital antenatal interventions in pregnant women were included. Outcomes included maternal depression, anxiety, fear of childbirth, self-efficacy, and small-for-gestational-age (SGA) incidence. Random-effects models were used, and standardized mean differences (SMDs) and odds ratios (ORs) were calculated. Heterogeneity was assessed using I² statistics. Twelve studies involving 4,982 participants were included. No significant effects were observed for depression (SMD = - 0.18; 95% CI: -0.45 to 0.09; I² = 86.5%; p = 0.188), anxiety (SMD = - 0.10; 95% CI: -0.66 to 0.46; I² = 92.8%; p = 0.723), or self-efficacy (SMD = 0.56; 95% CI: -0.11 to 1.23; I² = 90.6%; p = 0.102). A reduction in fear of childbirth did not reach statistical significance (SMD = - 0.53; 95% CI: -1.06 to 0.003; p = 0.051. No significant association was found for SGA (OR = 0.73; 95% CI: 0.17-3.14; p = 0.670). Substantial heterogeneity was present across outcomes, limiting the interpretability of pooled estimates. Current evidence, characterized by substantial heterogeneity, does not demonstrate statistically significant effects of online-based antenatal education on maternal depression, anxiety, or fear, nor on improving self-efficacy or preventing SGA infants. However, the high heterogeneity (I² >85% for most outcomes) indicates that these pooled estimates are exploratory, and clinically meaningful effects for specific intervention types cannot be ruled out. Findings should be interpreted cautiously.
In order to guarantee sufficient growth, digestive stability, and long-term productivity in dairy heifers, proper nutritional management is crucial both before and after weaning. This case study assesses the impact of dietary modifications on growth performance and digestive parameters in commercial settings and details a field observation of concentrate overload in young Holstein heifers. From 77 to 165 days of age, the body weight (BW), average daily gain (ADG), body condition score (BCS), feed intake, and fecal characteristics of 15 calves were monitored. Infectious and parasitic causes of diarrhea were ruled out by fecal examinations. Ad libitum concentrate feeding resulted in low fecal scores with undigested grain particles and acidic smell, starch intake exceeding requirements, and concentrate intake reaching up to 6 kg as fed head×day. The BCS gradually rose, and ADG peaked at 1.64 kg/day. Forage intake increased, fecal consistency improved, and ADG stabilized after restricting concentrate allowance to 2.5% of BW. These results underline the significance of controlling starch intake and concentrate allowance to avoid excessive growth and digestive disorders in developing dairy heifers, and they support a nutritional basis for the observed digestive imbalance.
We report the case of a 69-year-old Hispanic female with end-stage renal disease (ESRD) on hemodialysis and a complex medical history who presented with acute altered mental status shortly after initiating valacyclovir at a non-renally adjusted dose. The patient was admitted to inpatient services and treated with a presumptive diagnosis of valacyclovir-associated neurotoxicity (VAN). The patient received hemodialysis for three consecutive days, resulting in neurologic improvement. Additional competing causes of altered mental status and encephalopathy were investigated and ruled out over the course of a five-day hospitalization. The patient was subsequently discharged with a diagnosis of VAN. This case underscores the importance of proper renal dose adjustment and medication safety in patients with ESRD to prevent serious, avoidable adverse drug events.
Platelet factor 4-polyanion enzyme-linked immunosorbent assays (ELISAs) are considered highly sensitive for diagnosing heparin-induced thrombocytopenia (HIT), such that current practice guidelines recommend use of ELISA-negative results to exclude HIT. Once HIT is ruled out, alternative, non-heparin-based anticoagulant treatments are ceased, and heparin reintroduction frequently occurs. Antigen-based and PF4-dependent functional testing were used to study PF4/polyvinylsulfonate ELISA-negative platelet-activating antibodies in HIT-suspected patients. Three patients with clinical presentations consistent with HIT tested negative in an ELISA using PF4-polyvinylsulfonate (PF4/PVS), an antigenic target very commonly used for HIT antibody screening. All three patients demonstrated PF4-dependent platelet activation in functional testing that was sensitive to blockade of platelet FcγRIIa receptors and inhibited by high concentrations of heparin, consistent with pathogenic HIT antibodies. Functional testing-based screening of 500 ELISA-negative patients identified three additional patients whose sera activated platelets in a PF4- and FcγRIIa-dependent manner and had clinical histories consistent with HIT. Five of the six ELISA-negative HIT patients were re-exposed to heparin, which precipitated a decrease in platelet counts in all re-exposed patients, and one patient developed a new thrombus. Recognition of ELISA-negative HIT is critical to avoid harm due to the cessation of alternative anticoagulation therapy and re-exposure of these patients to heparin.
To compare accuracy, precision, recall, F1 and time spent using commercial tools to identify physiotherapy trials based on title and abstract, compared with a human approach. This study compared two approaches for title and abstract screening of 10,793 newly published records. In the reference standard human approach, two reviewers independently screened records using pre-specified rules to assess relevance to physiotherapy. A third person resolved disagreements. We evaluated three LLMs (gpt-4o, gpt-4.5, gpt-4-turbo) within two commercial, web-based tools (ChatGPT and Co-pilot). Outcomes were accuracy (proportion of records that model correctly identified as relevant or irrelevant), precision (proportion of records identified as relevant that were considered as relevant by human approach), recall (the proportion of all actual relevant records that the model successfully identified), F1 (harmonic mean of precision and recall) and time spent. Exploratory analyses compared the performance of the commercial tools with local approaches, including local LLMs implementation, machine learning and natural language processing. Commercial tools showed comparable performance across all metrics (ChatGPT vs Copilot: accuracy: 83% vs 86%; precision: 44% vs 48%; recall: 88% vs 87%; F1: 59% vs 62%). The total time spent using commercial tools with a labelled dataset was equivalent to 37% of the time required for the human-only screening process. Exploratory analysis showed that the API-based implementation has comparable performance (accuracy: 82%; precision: 42%; recall: 93%; F1: 58%). Yet, LLM-based models demonstrated lower performance compared with other local, custom-adapted automation approaches such as machine learning and natural language processing. This proof-of-concept study demonstrates that commercial web-based LLMs may have sufficient accuracy to support title and abstract screening and substantially reduce the time to identify field-specific trials. However, alternative approaches, including machine learning or natural language processing, could achieve screening performance similar to or slightly higher than that of commercial tools, yet they require a series of pre-processing steps for implementation.
The aim of this study is to explore the conditions of pregnancy and gynaecological care for women in prison in Spain. An exploratory qualitative research study was carried out, involving 125 semi-structured interviews with 79 prison professionals and 46 women prisoners in 16 prisons in Spain. The participants were selected through theoretical sampling. The study was based on a thematic analytical procedure inspired by grounded theory, which produced certain unexpected results that are the focus of this study. The results of the interviews reveal that obstetric violence (OV) can take place through actors other than healthcare professionals, such as the police force when they guard and transfer pregnant inmates to obstetrics appointments or other inmates who require gynaecological services. During gynaecological examinations and tests, female inmates are kept in handcuffs or restraints and with police officers present in the room, violating their privacy and rights. The responses of gynaecologists to this situation are diverse. Gynaecologists should be the ones with authority in the medical consultations of female prisoners, and they should not allow the humiliation and violation of the rights of these women, as stated in the United Nations Bangkok Rules. Most female inmates are not dangerous, with non-aggressive and non-violent offences, so they would not put the lives of healthcare personnel at risk, and the continuation of this practice is more a question of compliance with protocols than of real risk.
Work in eating disorder (ED) services presents unique challenges and rewards that may affect clinicians' work-related and personal wellbeing. However, research on ED clinician needs, views, and experiences is still sparse, despite major service changes since the COVID pandemic. This study aims to explore and conceptualise NHS ED clinicians' work-related experiences, challenges, and needs, in order to inform future clinicians wellbeing and service improvement strategies. Clinicians working in ED services (N = 19) were interviewed using a semi-structured interview guide that probed their professional experiences, work-related needs, and views. Interviews were analysed using NVivo, following guidance from Braun and Clarke (2006) for reflexive thematic analysis. A holistic ecological systems framework for ED services was created, comprised of five levels of influence: intrinsic, intra-personal, departmental, systemic, and societal. These levels contain nine themes: [1] clinician motivation for working in ED services [2], complexities of ED management [3], clinician personality and emotional disposition [4], team dynamics [5], supervision, management, and organizational support [6], service-level concerns [7], macro-level systemic concerns [8], broader societal challenges in ED care, and [9] COVID-related challenges. Key concerns included the chronic nature and risk of EDs, growing service demands amid limited resources, and regulation through guidelines and commissioning targets. This presented framework illustrates the multifaceted array of complexities faced by ED clinicians. The interplay of personal, inter-personal, and systemic factors is explored, with clinicians' interest in and commitment to ED care at the core of the framework. These areas can be targeted to improve clinician job satisfaction and reduce burnout risk, with the goal to provide optimal patient care. This study explores the experiences and wellbeing of clinicians working in NHS eating disorder (ED) services. Through interviews with clinicians, the research explored both the positive and difficult parts of their job. While staff felt strongly committed to helping people with EDs, many also described feeling emotionally drained and frustrated. This was often due to high workloads, not enough resources, and long waiting lists. Clinicians found it especially hard when they had to follow strict service rules that didn’t work well for individual patients, and when they had to manage complex medical risks. Supportive teams and good supervision helped some staff cope. Wider problems like staff shortages, poor communication between services, and lack of funding compounded emotional strain. The findings show that ED clinicians urgently need more support, including better resources, more flexible ways of working, and proper training, to give safe, effective care without burning out.
Given the rapid mutation and high transmissibility of coronaviruses, especially SARS-CoV-2, comparative genomic studies are crucial for understanding viral evolution, transmission dynamics, and therapeutic development. In prior work, we analyzed and compared the spectral distribution patterns of various k-mer subsets across 920 genome sequences, spanning from primates to prokaryotes. This revealed an evolutionary mechanism in genome sequences, indicating the presence of both CG and TA-specific selection modes. In the present study, we further investigate the specific selection modes in coronavirus genomic sequences by examining the intrinsic distribution rules of 32 XYi 6-mer subset spectra. Our results show that coronavirus genomes exhibit only the CG-specific selection mode, with no evidence of TA-specific selection. Using the CG-specific selection mode, we identified CG1 6-mers as the fundamental subset underlying coronavirus genome evolution. To validate the CG1 subset, we constructed phylogenetic relationships for a set of coronaviruses and SARS-CoV-2 variant genomes. Comparative analysis confirmed that the resulting phylogenetic relationships align more closely with established knowledge. This study thus provides a theoretical framework for inferring phylogenetic relationships at the whole-genome level.
Immersive technologies such as 360-degree video virtual reality (360VR) provide unique opportunities to simulate representative environments to investigate decision-making in a safe and cost-effective manner. Inclusion of multi-sensory visual, contextual, and auditory information is important to enhance simulator psychological fidelity. Yet, the influence of increased sensory information on decision-making, presence, and cognitive load in 360VR compared to less immersive two-dimensional video simulators is unknown. This study investigated multi-sensory information, presence, and cognitive load across immersion conditions (360VR and two-dimensional video) in an exemplar sport-specific decision-making task. Fifteen higher-skilled and 15 lesser-skilled Australian Rules Football players completed a decision-making task which presented visual information only, visual and contextual information, and visual, contextual and auditory information. Overall, there were little significant performance difference between simulators. There was a significant decrease in decision-making performance across both skill levels and simulators as contextual and auditory information was added. Decision-making performance decline was more pronounced for lesser-skilled than higher-skilled participants, when they had to utilise contextual information to make riskier decisions to win the game. Significantly more accurate decisions were made when congruent, compared to incongruent, auditory information was presented, particularly in two-dimensional video. Perceptions of presence and cognitive load were significantly higher in 360VR than two-dimensional video, regardless of skill level, whilst across both simulators, cognitive load increased as sensory information was added. These findings indicate provision of multi-sensory information is more important for decision-making than simulator immersion and presence. Therefore, a focus on increasing simulator immersion should be done so with caution.
In clinical lung transplantation (LTx), direct and continuous measurement of donor lung temperature under static ice storage has rarely been reported. Although assumed to be 4°C, recent studies suggest temperatures may approach 0°C. This study aimed to establish direct, continuous monitoring of lung temperature, fit temperature changes to a mathematical model, and evaluate their association with clinical outcomes. This prospective single-center study included clinical LTx cases between July 2024 and January 2025. Direct temperature monitoring at the end of preservation (n = 15) and continuous monitoring during preservation (n = 10) were performed at the lung surface and interlobar region using a sterile data logger. Temperature curves were fitted (n = 8) with an exponential decay model validated in porcine experiments. Associations between end-of-preservation interlobar temperature (≤4°C vs >4°C) and post-LTx outcomes were examined (n = 15). Median end-of-preservation temperatures were 8.6°C (range: 1.21-13.35°C) at the surface and 5.3°C (0.15-12.10°C) at the interlobar region, but intercase variability was observed. Nevertheless, temperature curves generally remained above freezing. Interlobar curves showed better model fitting than surface curves (median R-squared: 0.98 vs 0.95). The >4°C interlobar group demonstrated significantly better primary graft dysfunction grades post-LTx (p = 0.04), a trend not observed with surface temperature. Direct measurement showed lungs preserved on ice generally remained above 0°C, but freezing injury could not be completely ruled out. Interlobar temperature more closely followed the model, reflecting lung temperature dynamics. Interlobar temperature >4°C was associated with better graft function.
This study investigated mechanical properties of composite materials consisting of an isotactic polypropylene (iPP) matrix reinforced with whisker-like fillers: carbon nanofibers (CBNF) and wollastonite (WN). We strove to develop mechanical models specifically for predicting yield stress and fracture toughness. Experimentally obtained results validated findings obtained using the proposed models. Regarding the elastic modulus, data suggest that conventional rules of mixture, typically used for glass fiber-reinforced polymers, remain applicable, indicating that filler addition enhances stiffness in a predictable manner. However, yield stress and fracture toughness exhibited distinct behaviors. Results revealed that these properties are governed predominantly by shear yielding of the iPP matrix rather than reinforcement effect of the fillers. Despite the presence of whiskers, the overall yield and fracture mechanisms depend heavily on the matrix's plastic deformation and energy dissipation. The constructed models consistently explain these findings, supporting quantitative evaluation of the matrix's contribution. These results emphasize that developing high-performance iPP composites requires knowledge of the intrinsic ductile properties of the matrix alongside filler selection and dispersion.
On 1 January 2022, assisted suicide became legal in Austria with the enactment of the Dying Decree Law (Sterbeverfügungsgesetz, StVfG). This law has posed complex practical and ethical challenges for nursing facilities and hospitals. Medical and nursing directors are tasked with guiding their staff amidst legal uncertainties, emotional burdens, and limited institutional dialogue. This study aimed to assess directors' self-reported knowledge of the law, their experiences managing assisted suicide requests, their perceived adequacy of support in navigating the legal framework, and the presence of institutional guidelines. A cross-sectional mixed-methods study. An online questionnaire was used to collect data from 239 medical and nursing directors across all nine federal states of Austria (mean age = 49.5 years, SD = 8.5; 65.7% female, 32.2% male; 23.7% working in faith-based institutions, 61.9% in non-faith-based institutions, and 14.4% prefer not to disclose). Quantitative data were analysed using chi-square tests, t tests, and ANOVAs, while thematic analysis was applied to open-ended responses. 44.0% of directors knew the regulations of the Dying Decree Law but were insecure in regards to the application in practice, while 13.4% of directors reported no familiarity with Law at all. Legal familiarity correlated with gender (p = 0.020, V = 0.183) and institutional religious affiliation (p = 0.019, V = 0.197). Satisfaction with institutional guidelines was linked to gender (p = 0.004, r = 0.15), religious affiliation (p = 0.003, r = -0.15), and institution type (p = 0.011, η² = 0.126). While 36.2% reported no institutional guidelines on assisted suicide, 13.8% were unaware of their existence. The findings reveal knowledge gaps, institutional disparities, and limited guidance on the Dying Decree Law. Directors report insufficient preparedness, highlighting the need for clearer institutional guidelines and enhanced legal, ethical, and psychological support. This study was registered in the Open Science Framework (OSF) at https://osf.io/bgpsa. How prepared are healthcare directors in Austria to deal with assisted suicide requests? In January 2022, assisted suicide became legal in Austria under a new law called the Dying Decree Law. This change created new responsibilities and challenges for healthcare institutions such as hospitals and nursing homes. Medical and nursing directors play a key role in helping staff respond to requests for assisted suicide, but little was known about how well prepared they feel to do this. This study explored how familiar medical and nursing directors in Austria are with the new law, how confident they feel applying it in practice, and whether clear institutional guidelines on assisted suicide are available. An online survey was completed by 239 medical and nursing directors from all nine Austrian federal states. The survey included multiple-choice questions and open-ended responses to capture both numerical data and personal experiences. The findings show that many directors feel uncertain about the law. While some were familiar with the legal rules, nearly half felt insecure about how to apply them in real situations, and some had no knowledge of the law at all. Knowledge and satisfaction with institutional guidance differed depending on gender, whether the institution was faith-based, and the type of healthcare setting. More than one third of directors reported that their institution had no guidelines on assisted suicide, and others were unsure whether such guidelines existed. Overall, the study highlights important gaps in knowledge, guidance and support. Many directors feel unprepared to manage assisted suicide requests and the emotional and ethical challenges involved. The results suggest a clear need for better legal information, ethical guidance, psychological support, and clear institutional policies. Improving national coordination and institutional structures could help ensure consistent, ethical, and high-quality end-of-life care in Austria.
Global warming influences rising temperatures, making outdoor physical education classes progressively challenging to organize. While heat acclimatization is essential for athletic development, the conventional emphasis on "endurance" training in Chinese schools sometimes overlook the physical limitations of youths. This paper reviews outdoor sports in heat acclimatization related published articles and examines the body's response to heat stress and evaluates whether physical education professionals are prepared to reduce these risks. This review found that many coaches and teachers lack the requisite practical knowledge to prevent heat stress, often reacting to issues only post-occurrence; a comparison of international standards highlights a further issue: unlike other countries, which follows strict guidelines, China lacks clear and specific guidelines for youth sports safety in heat acclimatization; Heat stress significantly affects physical performance and willingness to participate in activities among youths and heat acclimatization training is an effective intervention method. To address this, we recommend using the student military training period as an opportunity to build heat acclimatization. Additionally, physical education classes must be updated to prioritize hydration, proper clothing, and controlled exercise intensity during hot weather. Establishing these standard safety rules is essential to protect students and ensure they can continue participating in sports safely.
