Predictors of COVID-Related stress in a community sample in Turkey: a cross-sectional study.

The distinctive mental health features associated with COVID-19 have gained importance as the psychological effects of the pandemic on the community become more visible. This study aims to assess the COVID-related stress status and associated factors in the community sample of Turkey. The sample of this cross-sectional study is composed of 2.065 people between the ages of 18-90. Data were collected through an online survey prepared by Google.docs between October-December, 2020. Mild to moderate stress was found in the community with the most common symptoms of the fear of contamination and danger. Some variables, such as being female and the severity of COVID-19 illness, were associated with higher COVID-related stress. Vulnerable groups associated with high stress should be monitored during the pandemic. The findings of this study will guide the practices of professionals working in the field of public health, healthcare, or mental health in possible future pandemics.

Knowledge levels of stroke among hypertensive and diabetic patients in a tertiary hospital.

BACKGROUND: Strokes represent a major global health challenge, as they now affect up to 15 million people annually, with increasing mortality rates accompanying growing prevalence. In Saudi Arabia, hypertension (HTN) and diabetes mellitus (DM) have been identified as major contributors to stroke risk, with a combination of HTN and DM significantly magnifying the risk of strokes. While there have been global improvements in stroke prevention, recently knowledge levels vary significantly worldwide, and multiple studies in Saudi Arabia show inconsistent awareness levels. OBJECTIVES: This study seeks to develop insights for the development of tailored prevention programs that align with Saudi Vision 2030 in terms of enhancing quality of life. Thus, the aim of the study is to assess knowledge levels of stroke risk factors, warning signs, symptoms, and prevention methods among high-risk groups (HTN and DM patients) at King Saud University Medical City (KSUMC). METHODS: This was an analytical cross-sectional study conducted among 422 participants from June 2022 to January 2023, using a validated Arabic questionnaire taken, with permission, from previous studies. All HTN and T2DM patients in the waiting areas of the outpatient clinics at KSUMC, Riyadh were included as part of the random sampling, though patients below 20-years-old and those with other endocrine disorders were then excluded. RESULTS: The majority of participants were male (64.5 %). The analysis showed that 66.1 % of participants had "poor total knowledge" of stroke factors. Half of the participants (50.5 %) had "poor knowledge" about stroke risk factors, though the most commonly identified risk factor was "hypertension". Additionally, the findings showed that 46.4 % of participants had "poor knowledge" of stroke warning signs and symptoms, with the most commonly identified warning sign being "difficulty in speaking." Nearly half of participants (46.4 %) had "good knowledge" of stroke prevention methods; however, "regular exercise" was the most commonly identified prevention method. CONCLUSION: Although the participants displayed decent knowledge of stroke prevention methods, several notable deficits in overall knowledge of stroke factors emerged. In particular, knowledge of stroke risk factors and warning signs and symptoms among participants was inadequate. This implies that healthcare providers should seek to launch campaigns addressing stroke knowledge mainly among high-risk groups, potentially distributing brochures about stroke knowledge in the relevant clinics and seeking to provide a range of educational content by means of social media.

SARS-CoV-2 Seroprevalence Trends in the Netherlands in the Variant of Concern Era: Input for Future Response.

BACKGROUND: To inform future response planning we aimed to assess SARS-CoV-2 trends in infection- and/or vaccine-induced immunity, including breakthrough infections, among (sub)groups, professions and regions in the Dutch population during the Variant of Concern (VOC)-era. METHODS: In this prospective population-based cohort, randomly selected participants (n = 9985) aged 1-92 years (recruited early-2020) donated home-collected fingerstick-blood samples at six timepoints in 2021/2022, covering waves dominated by Alpha, Delta, and multiple Omicron (sub-)variants. IgG antibody assessment against Spike-S1 and Nucleoprotein was combined with vaccination- and testing data to estimate infection-induced (inf) and total (infection- and vaccination-induced) seroprevalence. RESULTS: Nationwide inf-seroprevalence rose modestly from 12% (95% CI 11-13) since Alpha to 26% (95% CI 24-28) amidst Delta, while total seroprevalence increased rapidly to 87% (95% CI 85-88), particularly in elderly and those with comorbidities (i.e., vulnerable groups). Interestingly, highest infection rates were noticeable among low/middle educated elderly, non-Western, those in contact professions, adolescents and young adults, and in low-vaccination coverage regions. Following Omicron emergence, inf-seroprevalence elevated sharply to 62% (95% CI 59-65) and further to 86% (95% CI 83-90) in late-2022, with frequent breakthrough infections and decreasing seroprevalence dissimilarities between most groups. Whereas > 90% of < 60-year-olds had been infected at least once, 30% of vaccinated vulnerable individuals had still not acquired hybrid immunity. CONCLUSIONS: Groups identified to have been infected disproportionally during the acute phase of the pandemic require specific attention in evaluation of control measures and future response planning worldwide. Furthermore, ongoing tailored vaccination efforts and (sero-)monitoring of vulnerable groups may remain important.

Factors potentially contributing to the decline of the mpox outbreak in the Netherlands, 2022 and 2023.

BackgroundIn 2022 and 2023, a global outbreak of mpox affected mostly gay, bisexual and other men having sex with men (GBMSM). Outbreak control in the Netherlands included isolation, quarantine, post-exposure prophylaxis vaccination and primary preventive vaccination (PPV).AimWe describe the course of the outbreak, the vaccination programme, vaccine effectiveness (VE) of full vaccination against symptomatic disease, and trends in behaviour to generate hypotheses about factors that influenced the outbreak's decline.MethodsIn this observational study, we collected data from public health services on notified cases, number of PPV invitations and PPV doses administered. We calculated PPV uptake and coverage. Trends in behavioural data of GBMSM visiting sexual health centres were analysed for all consultations in 2022. We estimated VE using the screening method.ResultsUntil 31 December 2023, 1,294 mpox cases were reported. The outbreak peaked in early July 2022 and then declined sharply. PPV started on 25 July 2022; in total 29,851 doses were administered, 45.8% received at least one dose, 35.4% were fully vaccinated. The estimated VE was 68.2% (95% CI 4.3-89.5%). We did not observe an evident decrease in high-risk behaviour.DiscussionIt is unlikely that PPV was a driver of the outbreak's decline, as incidence started to decline well before the start of the PPV programme. The possible impact of behavioural change could not be demonstrated with the available indicators, however, the data had limitations, hampering interpretation. We hypothesise that infection-induced immunity in high-risk groups was an important factor explaining the decline.

Pancreatic cancer: from early detection to personalized treatment approaches.

Pancreatic cancer is notorious for its persistently poor prognosis and health outcomes, so some of the questions that may be begged are "Why is it mostly diagnosed at end stage?", "What could we possibly do with the advancing technology in today's world to detect early pancreatic cancer and intervene?", and "Are there any implementation of the existing novel imaging technologies?". Well, to start with, this is in part because the majority of patients presented would already have reached a locally advanced or metastatic stage at the time of diagnosis due to its highly aggressive characteristics and lack of symptoms. Due to this striking disparity in survival, advancements in early detection and intervention are likely to significantly increase patients' survival. Presently, screening is frequently used in high-risk individuals in order to obtain an early pancreatic cancer diagnosis. Having a thorough understanding of the pathogenesis and risk factors of pancreatic cancer may enable us to identify individuals at high risk, diagnose the disease early, and begin treatment promptly. In this review, the authors outline the clinical hurdles to early pancreatic cancer detection, describe high-risk populations, and discuss current screening initiatives for high-risk individuals. The ultimate goal of this current review is to study the roles of both traditional and novel imaging modalities for early pancreatic cancer detection. A lot of the novel imaging techniques mentioned seem promising, but they need to be put to the test on a large scale and may need to be combined with other non-invasive biomarkers before they can be widely used.

Impact of fatalistic approaches in the health crisis: COVID-19 example.

BACKGROUND: When faced with a health crisis, most people tend to seek solutions through modern or traditional medicine. However, there is a group of people who tend to take a fatalistic approach to health crises and tend not to do what is necessary. When such approaches are exhibited in disadvantaged groups, there may be a chain reaction resulting in much more important problems. OBJECTIVE: The aim of this study is to determine whether the fatalistic approach is realized during a health crisis period in people 65 years and older, pregnant women, people with chronic diseases, and healthcare workers who are considered disadvantaged. Researchers also examined whether there were sociodemographic characteristics that made a difference in these attitudes among those who were determined to have a fatalistic approach. METHODS: The research was conducted with a quantitative method. The sample calculation was performed and it was decided to reach 196 people. A self-report scale was used for fatalism. RESULTS: It was determined that the participants had a moderate level of fatalism. It was seen that there was a difference between the groups in terms of fatalistic behavior. It was observed that women, divorced people, people without alcohol and smoking habits, people who live alone, and people who think their health is poor tend to behave more fatalistic. CONCLUSION: The tendency to show fatalistic behavior was found to be higher in the group of 65 years and older. Sociodemographic characteristics are associated with fatalistic behavior.

Flow cytometric minimal residual disease measurement accounting for cytogenetics in children with non-high-risk acute lymphoblastic leukemia treated according to the ALL-MB 2008 protocol.

BACKGROUND: Quantitative measurement of minimal residual disease (MRD) is the "gold standard" for estimating the response to therapy in childhood B-cell precursor acute lymphoblastic leukemia (BCP-ALL). Nevertheless, the speed of the MRD response differs for different cytogenetic subgroups. Here we present results of MRD measurement in children with BCP-ALL, in terms of genetic subgroups with relation to clinically defined risk groups. METHODS: A total of 485 children with non-high-risk BCP-ALL with available cytogenetic data and MRD studied at the end-of-induction (EOI) by multicolor flow cytometry (MFC) were included. All patients were treated with standard-risk (SR) of intermediate-risk (ImR) regimens of "ALL-MB 2008" reduced-intensity protocol. RESULTS AND DISCUSSION: Among all study group patients, 203 were found to have low-risk cytogenetics (ETV6::RUNX1 or high hyperdiploidy), while remaining 282 children were classified in intermediate cytogenetic risk group. For the patients with favorable and intermediate risk cytogenetics, the most significant thresholds for MFC-MRD values were different: 0.03% and 0.04% respectively. Nevertheless, the most meaningful thresholds were different for clinically defined SR and ImR groups. For the SR group, irrespective to presence/absence of favorable genetic lesions, MFC-MRD threshold of 0.1% was the most clinically valuable, although for ImR group the most informative thresholds were different in patients from low-(0.03%) and intermediate (0.01%) cytogenetic risk groups. CONCLUSION: Our data show that combining clinical risk factors with MFC-MRD measurement is the most useful tool for risk group stratification of children with BCP-ALL in the reduced-intensity protocols. However, this algorithm can be supplemented with cytogenetic data for part of the ImR group.

[Risk factors for the acquisition of Sexually Transmitted Infections in sex workers: a systematic review]. / Factores de riesgo para la adquisición de Infecciones de Transmisión Sexual en trabajadores/as del sexo: revisión sistemática.

OBJECTIVE: Sexually Transmitted Infections (STI), as their name suggests, are infections caused by more than thirty different bacteria, viruses, and parasites and are transmitted through sexual contact, including vaginal, anal, or oral intercourse, although some sexually transmitted infections can also transmitted from mother to child during pregnancy, childbirth and lactation. According to World Health Organization, one of the main populations at risk for acquiring these diseases are sex workers and their clients. Due to the high prevalence, the characteristics and behaviors that favor the development of these diseases are analyzed. The main objective of this paper was to analyze the risk factors in the acquisition of sexually transmitted diseases in the population of sex workers. METHODS: A literature search was conducted in Scopus, Pubmed, CINAHL, Medline, LILACS and IBECS, of observational, longitudinal and mixed methods studies conducted in sex workers and published between January 2011 and March 2021, with a final sample of fourty-three articles. The mixed methods assessment tool (MMAT) was used to assess the methodological quality of the papers. RESULTS: After analyzing the literature, eleven groups of risk factors related to the acquisition of sexually transmitted diseases were obtained, these being economic factors, factors related to sexual practices, drug use, sex work, education, health problems, country of origin and mobility, partner, age, violence and other factors not belonging to the previous categories. CONCLUSIONS: Sex workers have numerous characteristics and behaviors that make them vulnerable to sexually transmitted infections. Of note are years of prostitution, drug use, number of partners and condom use, which are key factors for future prevention and intervention strategies, as well as research.

OBJETIVO: Las Infecciones de Transmisión Sexual (ITS) son infecciones causadas por más de treinta bacterias, virus y parásitos diferentes, que se transmiten por contacto sexual, incluido el coito vaginal, anal o bucal, aunque algunas infecciones también pueden transmitirse de la madre al hijo durante el embarazo, el parto y la lactancia. Según la Organización Mundial de la Salud, una de las principales poblaciones de riesgo para la adquisición de estas infecciones son los/las trabajadores/as del sexo y sus clientes. El objetivo de este trabajo fue analizar los factores de riesgo en la adquisición de infecciones de transmisión sexual en la población de trabajadores/as del sexo. METODOS: Se realizó una revisión sistemática mediante búsqueda en Scopus, Pubmed, CINAHL, Medline, LILACS e IBECS, de estudios observacionales, longitudinales y mixtos realizados en trabajadores/as del sexo que fueron publicados entre enero de 2011 y marzo de 2021, obteniendo una muestra final de cuarenta y tres artículos. La herramienta de evaluación de métodos mixtos (mixed methods assessment tool) fue utilizada para evaluar la calidad metodológica de los trabajos. RESULTADOS: Después de analizar la bibliografía se obtuvieron once grupos de factores de riesgo relacionados con la adquisición de ITS, siendo estos factores económicos, relacionados con las prácticas sexuales, consumo de drogas, trabajo sexual, educación, problemas de salud, país de origen y movilidad, pareja, edad, violencia y otros factores no pertenecientes a las anteriores categorías. CONCLUSIONES: Las/os profesionales del sexo tienen numerosas características y comportamientos que les convierten en una población vulnerable a las ITS. Destacan los años ejerciendo la prostitución, el consumo de drogas, el número de parejas y el uso del preservativo, siendo estos factores clave para futuras estrategias de prevención e intervención, así como de investigación.

Cost-effectiveness of active tuberculosis screening among high-risk populations in low tuberculosis incidence countries: a systematic review, 2008 to 2023.

BackgroundIn countries with a low TB incidence (≤ 10 cases/100,000 population), active pulmonary tuberculosis (PTB) mostly affects vulnerable populations with limited access to healthcare. Thus, passive case-finding systems may not be successful in detecting and treating cases and preventing further transmission. Active and cost-effective search strategies can overcome this problem.AimWe aimed to review the evidence on the cost-effectiveness (C-E) of active PTB screening programmes among high-risk populations in low TB incidence countries.MethodsWe performed a systematic literature search covering 2008-2023 on PubMed, Embase, Center for Reviews and Dissemination, including Database of Abstracts of Reviews of Effects (DARE), National Health Services Economic Evaluation Database (NHS EED), Global Index Medicus and Cochrane Central Register of Controlled Trials (CENTRAL).ResultsWe retrieved 6,318 articles and included nine in this review. All included studies had an active case-finding approach and used chest X-ray, tuberculin skin test, interferon-gamma release assay and a symptoms questionnaire for screening. The results indicate that screening immigrants from countries with a TB incidence > 40 cases per 100,000 population and other vulnerable populations as individuals from isolated communities, people experiencing homelessness, those accessing drug treatment services and contacts, is cost-effective in low-incidence countries.ConclusionIn low-incidence countries, targeting high-risk groups is C-E. However, due to the data heterogenicity, we were unable to compare C-E. Harmonisation of the methods for C-E analysis is needed and would facilitate comparisons. To outline comprehensive screening and its subsequent C-E analysis, researchers should consider multiple factors influencing screening methods and outcomes.

DNA damage levels in peripheral blood mononuclear cells before and after first cycle of chemotherapy have comparable prognostic values in germ cell tumor patients.

Background: Germ cell tumors (GCTs) represent the most frequent solid malignancy in young men. This malignancy is highly curable by cisplatin (CDDP)-based chemotherapy. However, there is a proportion of patients having a poor prognosis due to refractory disease or its relapse. No reliable biomarkers being able to timely and accurately stratify poor prognosis GCT patients are currently available. Previously, we have shown that chemotherapy-naïve GCT patients with higher DNA damage levels in peripheral blood mononuclear cells (PBMCs) have significantly worse prognosis compared to patients with lower DNA damage levels. Methods: DNA damage levels in PBMCs of both chemotherapy-naïve and first cycle chemotherapy-treated GCT patients have been assessed by standard alkaline comet assay and its styrene oxide (SO)-modified version. These levels were correlated with clinico-pathological characteristics. Results: We re-confirm prognostic value of DNA damage level in chemotherapy-naïve GCT patients and reveal that this prognosticator is equally effective in GCT patients after first cycle of CDDP-based chemotherapy. Furthermore, we demonstrate that SO-modified comet assay is comparably sensitive as standard alkaline comet assay in case of patients who underwent first cycle of CDDP-based chemotherapy, although it appears more suitable to detect DNA cross-links. Conclusion: We propose that DNA damage levels in PBMCs before and after first cycle of CCDP-based chemotherapy are comparable independent prognosticators for progression-free and overall survivals in GCT patients. Therefore, their clinical use is highly advised to stratify GCT patients to identify those who are most at risk of developing disease recurrence or relapse, allowing tailoring therapeutic interventions to poor prognosis individuals, and optimizing their care management and treatment regimen.

Analysis of Attitudes and Practices towards the Influenza Vaccine in High-Risk Adults in Poland.

This study aimed to understand Poles' attitudes and beliefs towards influenza vaccinations in the flu season of 2022-2023, especially among individuals at risk of flu complications. The cross-sectional survey-based study was carried out on a sample of 810 respondents. The questionnaire was disseminated electronically using social media and e-mail. The majority of respondents (71%) could identify "high-risk groups" recommended for influenza vaccination, and 52.01% of respondents reported receiving influenza vaccination at some point in the past, with 32.12% receiving it in the 2022-2023 flu season and 41.09% in the 2021-2022 season. The majority of respondents declaring acceptance of the vaccine for the 2022-2023 season were in the high-risk group. Only 17.28% of respondents declared receiving both influenza and SARS-CoV-2 vaccines in the 2022-2023 season, with the vast majority being respondents from the "high-risk group" (p < 0.0001). Only 26.12% of respondents declared their intention to continue influenza vaccination in the future. Of those expressing the intention to get vaccinated against the influenza virus in future seasons, 46.79% were from the "high-risk group" (p = 0.0087). Results suggest the need for further interaction and education with healthcare providers and targeted informational efforts for at-risk groups regarding the benefits of flu vaccination.

Diagnosis, Clinical Presentation and Management of Celiac Disease in Children and Adolescents in Poland.

Celiac disease (CD) is a chronic immune-mediated disorder triggered by the ingestion of gluten in genetically predisposed individuals, affecting about 1% of the general population in the developed world. In 2012, the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) recommendations for CD diagnoses in children and adolescents were introduced, allowing the "no-biopsy" approach if certain criteria were met. This approach was also confirmed in the revised guidelines published in 2020. Thus, the aim of this study was to assess-over a one-year period-the clinical presentations and current status of the management of children and adolescents diagnosed with CD in Poland. Medical records of children and adolescents, newly diagnosed with CD in 2022/2023 in three medical centers in Poland, were involved. Gastroenterologists completed the specific anonymous web-based forms developed in the CD SKILLS project, including data routinely assessed at individual visits about the diagnostic approach and clinical presentation of the disease. Our study assessed 100 patients (56% girls) with an age range 1.6-18.0 years. We found that 98% of patients were serologically tested prior to a CD diagnosis and 58% of patients were diagnosed using the "no-biopsy" approach. In the analyzed group, 40% belonged to a known risk group, only 22% had annual screening before the CD diagnosis (the longest for 9 years), and 19% showed no symptoms at the time of the CD diagnosis. Our research confirmed the applicability of the "no-biopsy" approach for the diagnosis of CD in children and adolescents in Poland, and also showed changes in the clinical picture of CD. Moreover, we highlight the need to introduce broad CD serological screening in risk groups of the Polish population.

[Social pediatric care situation and needs during the COVID-19 pandemic from 2020 to 2022. What is needed now?] / Sozialpädiatrische Versorgungssituation und -bedarfe in Zeiten der COVID-19-Pandemie 2020 bis 2022. Was wird jetzt gebraucht?

BACKGROUND: Children and adolescents with social pediatric care needs represent a group with special challenges. The aim of this qualitative study was to describe social pediatric care during the pandemic from the perspective of experts. From this, conclusions were to be drawn for any social pediatric care needs that may have arisen. METHODS: Between May and November 2022, 25 experts from the field of social pediatrics were interviewed using guided interviews on the following topics: deviations in care, utilization behavior of families, individual burdens and resources, and sustainable needs. The interviews were analyzed by two research assistants. RESULTS: Overall, the social pediatric care offer was temporarily clearly limited. While families who were already well connected before the pandemic could be adequately cared for with the help of telephone/video contacts, an unreported number of at-risk groups, were described, for example, those with low competence to act, who did not make use of services or did so with delays. It was observed that there was a need for care for newly developed mental disorders and regression in therapy due to limited opportunities for support, as well as a need to catch up on missed opportunities for early support in the case of developmental disorders. DISCUSSION: To meet the needs that have arisen, underserved families should be identified and cared for promptly, taking individual characteristics into account. To this end, for example, more outreach services should be established that reach affected families unbureaucratically.

Respiratory syncytial virus knowledge, attitudes, and perceptions among adults in the United States.

Respiratory syncytial virus (RSV) is associated with considerable morbidity and mortality among older adults (aged ≥60 years) and adults with certain chronic conditions in the United States (US). Despite this burden, no previous studies have assessed the knowledge, attitudes, and perceptions (KAP) of RSV among these populations. This study evaluates RSV-related KAP among US adults at increased risk of severe RSV infection. A cross-sectional, web-based survey was administered from May to June 2022 to better understand respiratory infection- and RSV-related KAP among US adults who are at risk of severe RSV infection. The survey included ≥200 adults in each of 4 subgroups: adults aged 60-89 years, and adults aged 18-59 years with ≥1 chronic cardiovascular condition, chronic pulmonary condition, or diabetes mellitus. Survey responses were analyzed descriptively overall and by subgroup, with exploratory logistic regression modeling used to evaluate characteristics associated with RSV awareness and concern. Among the 827 survey respondents, only 43.3% had ever heard of RSV (n = 358/827). The study identified key knowledge gaps (e.g. bacterial vs. viral nature of respiratory infections, RSV seasonality, common RSV symptoms, extent to which RSV causes respiratory infections in specific patient populations). Although 33.7% of RSV-aware adults (n = 120/356) reported being worried/very worried about RSV, 67.3% (n = 241/358) rarely consider RSV as a potential cause of their cold/flu-like symptoms. Results from this study highlight important knowledge gaps related to RSV, perceived risk, and severity of RSV. Findings can be used to support the development of tailored education efforts to support RSV prevention.

What is the context? Respiratory syncytial virus (RSV) is a common cause of illness among older adults (60 years and older) and adults with certain chronic conditions in the United States (US), with some adults experiencing severe RSV outcomes such as hospitalization or death.Despite this considerable burden, the awareness of RSV among these at-risk populations has never been studied until now.What is new? We assessed RSV-related knowledge, attitudes, and perceptions among US adults at increased risk of severe RSV infection (adults aged 60­89 years and adults aged 18­59 years with ≥1 chronic cardiovascular condition, chronic pulmonary condition, or diabetes).Among older and at-risk adults, 43.3% had ever heard of RSV, with a lower awareness in the older adult subgroup.Among adults at increased risk of severe RSV who are aware of RSV, less than 35% consider themselves to be knowledgeable about RSV and 16­19% were unable to assess their perceived risk of contracting RSV or potential severity of RSV should they contract it.Knowledge gaps specific to RSV include the viral nature of RSV, its seasonality, symptoms, extent to which it causes respiratory infections in specific patient populations, the difficulty distinguishing RSV from other respiratory infections based on symptoms alone, and the limited testing for RSV in routine clinical practice.What is the impact? Two RSV vaccines were recently approved in the US and are recommended for the prevention of RSV among adults aged 60 years and older with shared clinical decision making.Results from this study reveal limited awareness of RSV among adults in the US at increased risk of severe RSV and knowledge gaps among those aware of RSV.These findings can be used by healthcare providers initiating shared clinical decision-making conversations with their patients aged 60 years and older who are eligible for RSV vaccination, as well as to tailor RSV disease awareness educational interventions to healthcare providers and patients.

A machine learning approach to identify groups of patients with hematological malignant disorders.

BACKGROUND AND OBJECTIVE: Vaccination against SARS-CoV-2 in immunocompromised patients with hematologic malignancies (HM) is crucial to reduce the severity of COVID-19. Despite vaccination efforts, over a third of HM patients remain unresponsive, increasing their risk of severe breakthrough infections. This study aims to leverage machine learning's adaptability to COVID-19 dynamics, efficiently selecting patient-specific features to enhance predictions and improve healthcare strategies. Highlighting the complex COVID-hematology connection, the focus is on interpretable machine learning to provide valuable insights to clinicians and biologists. METHODS: The study evaluated a dataset with 1166 patients with hematological diseases. The output was the achievement or non-achievement of a serological response after full COVID-19 vaccination. Various machine learning methods were applied, with the best model selected based on metrics such as the Area Under the Curve (AUC), Sensitivity, Specificity, and Matthew Correlation Coefficient (MCC). Individual SHAP values were obtained for the best model, and Principal Component Analysis (PCA) was applied to these values. The patient profiles were then analyzed within identified clusters. RESULTS: Support vector machine (SVM) emerged as the best-performing model. PCA applied to SVM-derived SHAP values resulted in four perfectly separated clusters. These clusters are characterized by the proportion of patients that generate antibodies (PPGA). Cluster 1, with the second-highest PPGA (69.91%), included patients with aggressive diseases and factors contributing to increased immunodeficiency. Cluster 2 had the lowest PPGA (33.3%), but the small sample size limited conclusive findings. Cluster 3, representing the majority of the population, exhibited a high rate of antibody generation (84.39%) and a better prognosis compared to cluster 1. Cluster 4, with a PPGA of 66.33%, included patients with B-cell non-Hodgkin's lymphoma on corticosteroid therapy. CONCLUSIONS: The methodology successfully identified four separate patient clusters using Machine Learning and Explainable AI (XAI). We then analyzed each cluster based on the percentage of HM patients who generated antibodies after COVID-19 vaccination. The study suggests the methodology's potential applicability to other diseases, highlighting the importance of interpretable ML in healthcare research and decision-making.

Considering the impact of shift working on health.

Shift work is necessary for the provision of health services, especially in hospitals as it is the only way to provide continuous care to patients. Working at night is inconsistent with the body's biological clock and night shift working hugely disrupts the circadian and sleep wake cycles. In 2020, the World Health Organization classified night shift working as being a 'probable' class 2A carcinogen and a number of independent cohort studies of both night workers and shift workers have observed increased incidence of certain cancers. Altered sleep timing, food timing and light exposure typical for shift workers leads to an acute circadian disruption and misalignment of regulatory hormones. This straying from synchronisation has been shown to result in individuals being more vulnerable to a number of chronic health conditions. Night shift work disrupts the normal sleep-wake cycle, often leading to shortened sleep duration and excessive fatigue and the results of this are far reaching. This article will explore the full impact of shift working, questioning if current practices employed within the NHS should continue.

Facilitators and barriers to implementing chest radiography in tuberculosis systematic screening of clinically high-risk groups in Ethiopia: A qualitative study.

Background: Chest X-ray has been included in national tuberculosis screening algorithms as a sensitive tuberculosis screening tool among high-risk groups. However, the implementation was influenced by multiple factors. We aimed to explore facilitators and barriers to implementing chest X-ray in systematic tuberculosis screening of clinically high-risk groups in Addis Ababa, Ethiopia. Methods: We conducted face-to-face, in-depth interviews with purposively selected participants at tertiary-level hospitals and a tuberculosis program coordinator at the Ethiopian Ministry of Health, who coordinates chest X-ray-guided systematic tuberculosis screening. A framework analysis was conducted using the consolidated framework for implementation research. Results: We identified 11 constructs that influenced the implementation of the chest X-ray intervention. Facilitators included the relative sensitivity of chest X-ray over symptom-based screening, its potential integration into existing systems, technological advancements in the area, policies and laws supporting the screening intervention, and the quality of the evidence of the screening intervention. Barriers included implementation complexity, high costs of the intervention, knowledge gaps among healthcare providers, training gaps, low priority for chest X-ray screening at the healthcare facility level, and a lack of external support from the Ministry of Health and stakeholders. Conclusion: This study identified contextual factors that influence the implementation of chest X-ray guided systematic tuberculosis screening among clinically high-risk groups that healthcare facilities and health ministries may use for decision-making. Addressing the barriers identified by the study would help to improve the implementation of chest X-rays for improved tuberculosis case detection and prompt treatment in clinically high-risk groups.

Dynamics of a two-group model for assessing the impacts of pre-exposure prophylaxis, testing and risk behaviour change on the spread and control of HIV/AIDS in an MSM population.

Although much progress has been made in reducing the public health burden of the human immunodeficiency virus (HIV), which causes acquired immunodeficiency syndrome (AIDS), since its emergence in the 1980s (largely due to the large-scale use and availability of potent antiviral therapy, improved diagnostic and intervention and mitigation measures), HIV remains an important public health challenge globally, including in the United States. This study is based on the use of mathematical modeling approaches to assess the population-level impact of pre-exposure prophylaxis (PrEP), voluntary testing (to detect undetected HIV-infected individuals), and changes in human behavior (with respect to risk structure), on the spread and control of HIV/AIDS in an MSM (men-who-have sex-with-men) population. Specifically, a novel two-group mathematical model, which stratifies the total MSM population based on risk (low or high) of acquisition of HIV infection, is formulated. The model undergoes a PrEP-induced backward bifurcation when the control reproduction number of the model is less than one if the efficacy of PrEP to prevent a high-risk susceptible MSM individual from acquiring HIV infection is not perfect (the consequence of which is that, while necessary, having the reproduction number of the model less than one is no longer sufficient for the elimination of the disease in the MSM population). For the case where the efficacy of PrEP is perfect, this study shows that the disease-free equilibrium of the two-group model is globally-asymptotically stable when the associated control reproduction number of the model is less than one. Global sensitivity analysis was carried out to identify the main parameters of the model that have the highest influence on the value of the control reproduction number of the model (thereby, having the highest influence on the disease burden in the MSM population). Numerical simulations of the model, using a plausible range of parameter values, show that if half of the MSM population considered adhere strictly to the specified PrEP regimen (while other interventions are maintained at their baseline values), a reduction of about 22% of the new yearly HIV cases recorded at the peak of the disease could be averted (compared to the worst-case scenario where PrEP-based intervention is not implemented in the MSM population). The yearly reduction at the peak increases to about 50% if the PrEP coverage in the MSM population increases to 80%. This study showed, based on the parameter values used in the simulations, that the prospects of elimination of HIV/AIDS in the MSM community are promising if high-risk susceptible individuals are no more than 15% more likely to acquire HIV infection, in comparison to their low-risk counterparts. Furthermore, these prospects are significantly improved if undetected HIV-infected individuals are detected within an optimal period of time.

Empowering Riverine Communities in the Amazon: Strategies for Preventing Rabies.

Rabies, caused by the Lyssavirus genus, is a highly lethal zoonotic disease transmitted by animals such as bats and domestic and wild carnivores to humans, claiming nearly 100% of lives. In Brazil, recent evidence suggests an increasing role of bats in human deaths from rabies, particularly in the Amazon region. This neglected tropical disease disproportionately affects impoverished and vulnerable populations in rural areas, where approximately 80% of human cases are concentrated. This article presents research conducted in riverine communities of the Tapajós/Arapiuns Extractive Reserve in Brazil to combat rabies in September 2022. The study adopted a participatory and collaborative approach, involving community members, healthcare professionals, and educators. Prioritizing proactive interventions, the health team administered prophylactic vaccinations to 30 individuals residing in communities exposed to the Lyssavirus. Educational activities focused on dispelling myths and raising awareness about preventive measures, with 100% of individuals reporting prior doubts about the disease, emphasizing the essential nature of the clarification, especially regarding preventive aspects. This study underscores the importance of community involvement, personalized interventions, and ongoing education to effectively combat rabies. By reinforcing public health policies and promoting health education, we can empower communities to take proactive measures in rabies prevention, leading to a reduction in incidence and an improvement in quality of life.
