ObjectiveWrestling is a complex sport that requires a combination of strength, endurance, and wrestling-specific technical training. Endurance activities, such as running, are commonly performed for rapid weight reduction before competition. However, these activities can severely disrupt recovery and lead to significant declines in performance. This study aimed to examine the acute effects of endurance, strength, and wrestling training sessions on hydration status and performance parameters in young wrestlers, providing insights to guide more effective hydration and recovery strategies.MethodA total of 14 experienced young wrestlers participated in a crossover design, completing endurance, strength, and wrestling training sessions on separate days. The hydration status was assessed through urine specific gravity (USG) before and after each session. The performance measures included hand grip strength, back and leg strength tests, anaerobic power (vertical and horizontal jumps), respiratory muscle strength (maximal inspiratory pressure, MIP), and reaction time assessments.ResultsThe endurance training caused the most significant acute reductions in the hydration (USG increase: 0.016 ± 0.005 g/cm3, p &lt; 0.05) and body mass (BM; −1.89 ± 0.4%, p &lt; 0.05), along with immediate performance decrements in the back strength (−7.02 ± 1.2%, p &lt; 0.001), right-hand grip strength (−8.79 ± 2.1%, p &lt; 0.001), jump height (−7.26 ± 1.8%, p &lt; 0.001), and MIP (−9.01 ± 2.3%, p &lt; 0.001). The hydration levels in the endurance group did not fully recover by the next day (USG post-training vs. before the next day’s training: p &lt; 0.05). In contrast, the strength training improved the reaction time before the next day’s session (+5.6 ± 1.3%, p &lt; 0.05), while the attention remained unaffected across all training types.ConclusionEndurance training—commonly used for rapid weight loss—can acutely compromise hydration and reduce key performance measures, with recovery taking more time compared to strength or wrestling sessions. Given these findings, endurance sessions should be strategically scheduled before rest days or low-intensity technical training to minimize their negative effects on subsequent performance. Implementing enhanced hydration strategies during endurance-focused sessions may also help mitigate these acute impacts and optimize recovery and performance in young wrestlers.

IntroductionThis study aimed to examine the associations of exposure to light while sleeping at night and different sleep durations with attention-deficit/hyperactivity disorder (ADHD) among preschool children in China.MethodsA cross-sectional study including 4197 preschool children (2190 boys and 2007 girls) was conducted in 2021. Lamplight exposure during sleep and sleep duration were collected via a validated questionnaire. ADHD was assessed using the Conners Parental Symptom Questionnaire (PSQ). Associations of exposure to light while sleeping and sleep duration with ADHD were examined by multivariable logistic regression models.ResultsThe overall prevalence of ADHD was 3.7%. Compared to the children who slept with the lamplight off at night, those who slept with the lamplight on ≥3 nights/week were more likely to have ADHD after multivariable adjustment (OR=3.37; 95% CI: 1.95, 5.82; P-trend &lt;0.001). The risk associations of lamplight exposure during sleep with ADHD were similar in subgroups stratified by sex, picky eating, gestational hyperglycemia, and gestational anemia. Moreover, compared to the children with sleep duration of 10-12 hours/day, adjusted OR for ADHD was 1.64 (95% CI: 1.14, 2.35) for those with sleep duration &lt;10 hours/day and 2.69 (95% CI: 1.12, 6.44) for those who slept&gt;12 hours/day.DiscussionLamplight exposure during sleep at night was positively associated with ADHD among preschool children. Also, both sleep duration of &lt;10 hours/day and &gt;12 hours/day increased the likelihood of ADHD. Our novel findings suggest the importance of sleeping habit on the prevention of ADHD. Prospective and interventional studies are warranted to elucidate the observed associations.

IntroductionDepression is the most common co-morbid psychiatric disorder in patients with schizophrenia and has a negative effect on functional outcomes and quality of life. There are several possible pathways leading to depressive symptoms in schizophrenia. Self-disorders are disturbances in the deepest, pre-reflective level of the self and are suggested to be core features of schizophrenia. The relationship between self-disorders, and depressive symptoms has only been studied to a limited extent, and there are no longitudinal studies. This study aimed to explore the relationship between self-disorders at baseline and the development of depression over the follow-up periodMethodsSelf-disorders were examined with the Examination of Anomalous Self-Experience (EASE) instrument in 31 patients with schizophrenia during their first treatment. Seven years later we measured the total number of depressive episodes since the start of treatment.ResultsWe found a clear association between self-disorders at baseline and the total number of depressive episodes over the follow-up period.DiscussionSelf-disorders may play a role in the development of depression in schizophrenia. This may have implications for therapeutic approaches targeting a condition that is characterized by considerable suffering and an elevated risk of suicide.

BackgroundMeat is a good source of protein in the human diet, and more than three-quarters of the world’s population consumes it. It is the most perishable food item since it has enough nutrients to enable microbial growth. In underdeveloped nations, animals are routinely slaughtered and sold in unsanitary conditions, compromising the bacteriological quality and safety of the meat received from the animals. To protect customers’ health from numerous foodborne diseases this study aimed to determine the microbial quality and predictors of meat along the meat value chain in Northeast, Ethiopia.ObjectiveTo determine the bacteriological quality of meat and its predictors obtained from the Dessie City Administration’s municipal slaughterhouse and butcher shops.Materials and methodsA laboratory-based cross-sectional study design was used. In total 177 meat and 354 swab samples were collected. In addition, 177 meat handlers were randomly selected for knowledge, attitude, and practice assessment. All the samples were analyzed for the presence and counts of total viable count, total coliform count, fecal coliform count, and S. aureus. Multiple linear regression and student T-tests were used to analyze the data. Statistical significance was defined at a p-value of less than 0.05.ResultsThe total viable count of meat samples collected from slaughterhouse and butcher shops were 5.17 ± 0.13 and 6.5 ± 0.87 log CFU/g, respectively. The overall mean total viable count of the meat samples was 5.8 ± 0.1 log CFU/g. Meat samples collected from butcher shops were more highly contaminated than those collected from slaughterhouse. Hand hygiene of meat handlers, the microbial quality of water, and the educational status of meat handlers are all significant predictors of the microbial quality of raw meat along the meat value chain.Conclusion and recommendationThe meat microbial quality is poor and deteriorates along the meat value chain. The hands of meat handlers, the microbial quality of water used to wash the hands of meat handlers, and the educational status of meat handlers significantly affect the microbial quality of raw meat along the meat value chain. Hence, measures should be taken to improve the personal hygiene status of meat handlers and the quality of water used to wash hands and meat contact surfaces.

BackgroundSevere maternal outcome (SMO) encompasses women who survive life-threatening conditions either by chance or due to treatment quality, or who die. This concept assumes that severe maternal morbidity predicts mortality risk, enabling the analysis of risk factors for life-threatening outcomes and improving our understanding on the causes of maternal death. This study aims to determine the incidence of SMO and its leading causes in East Gojjam during a period of regional conflict.MethodsA prospective follow-up study was conducted at Debre Markos Comprehensive Specialized Hospital in East Gojjam from July 1, 2023, to February 30, 2024. The study included 367 women admitted with potentially life-threatening conditions, including 8 maternal deaths, using sub-Saharan Africa (SSA) and WHO Maternal Near-Miss (MNM) criteria. Data were entered into Epi Data v.4.6 and analyzed using SPSS v.27. The WHO MNM approach assessed SMO indicators and maternal health care quality were utilized.ResultsDuring the eight-month period, there were 3,167 live births, 359 potentially life-threatening conditions (PLTC), and 188 SMO cases (180 MNM and 8 maternal deaths). The SMO ratio was 59.4 per 1,000 live births (95% CI: 51, 68 per 1,000 live births). The MNM to mortality ratio, mortality index, and maternal mortality ratio were 22.5:1, 4.2%, and 252.6 per 100,000 live births, respectively. Over 80% of women with SMO showed evidence of organ dysfunction upon arrival or within 12 h of hospitalization. The leading causes of SMO were hypertensive disorders of pregnancy (HDP) and obstetric hemorrhage, including uterine rupture, with uterine rupture contributing to half of the maternal deaths.ConclusionThis study found that the incidence of SMO was comparable to that reported in most other studies. HDP was the primary cause of SMO, followed by obstetrical hemorrhage, consistent with other studies in Ethiopia. Uterine rupture was identified as the leading cause of maternal death. As this study was conducted in a single institution and in the period of severe armed conflict, it may not fully capture the range of maternal health issues across populations with varying healthcare access and socio-economic backgrounds. Caution should be exercised when generalizing these findings to the wider population.

BackgroundClimate change is reshaping public health, introducing extreme weather conditions and environmental stressors—such as high temperatures, atmospheric pollution, desertification, and storms (rain, thunder, and hail)—that critically impact mental health. Evidence increasingly links these factors to higher rates of suicide-related outcomes, including suicidal ideation, attempts, and self-harm. Such interactions underscore the importance of understanding how climate-driven mental health risks vary by environmental factor and gender, as gender-specific vulnerabilities shape responses to climate stressors.MethodsBy April 16, 2024, we conducted a comprehensive search of PubMed, Web of Science, Cochrane Library, PsycINFO, Scopus, ProQuest, and Embase. Two researchers independently reviewed studies and collected demographic data, systematically tracking and recording rates of suicidal ideation, suicide attempts, suicide deaths, self-harm, and anxiety. Data were rigorously cross-verified for accuracy and consistency.ResultsThe meta-analysis demonstrated significant associations between climate change variables and mental health outcomes. High temperatures and air pollution were linked to increased suicide attempts (OR: 1.40, 95% CI: 1.34–1.45) and suicide deaths (OR: 1.51, 95% CI: 1.44–1.58), particularly among males. Conversely, atmospheric pollution and desertification correlated with a reduced likelihood of suicidal ideation (OR: 0.73, 95% CI: 0.63–0.85). These findings highlight gender-specific mental health impacts, with females exhibiting higher rates of anxiety and self-harm, underscoring the urgent need for targeted interventions addressing climate-induced mental health risks.ConclusionsThis systematic review and meta-analysis reveal significant gender-specific mental health impacts of climate change, with females experiencing higher rates of anxiety, self-harm, and suicidal ideation, while males show greater incidences of suicide attempts and deaths. These findings emphasize the urgent need for targeted interventions and the integration of mental health services into climate policies to address these gender disparities.Systematic review registrationThis study is registered with PROSPERO [PROSPERO (york.ac.uk)] under the identifier [CRD42024534961].

IntroductionSmoking causes lung cancer and a wide range of acute and chronic diseases annually throughout the world. A fourth-generation behavioral framework, namely the Multi-Theory Model (MTM) of health behavior change was used to predict the initiation and maintenance of smoking cessation among health worker smokers.MethodsA cross-sectional study of 170 smoking healthcare workers was conducted in Kabul. A non-probability convenience sampling method was used to recruit respondents. A valid and reliable 37-item MTM-based questionnaire was administered to male smokers. Stepwise multiple regression was used to explain smoking cessation. The overall Cronbach’s alpha coefficient (α) for the initial and retention scales of the MTM variables was 0.80 and 0.79, respectively.ResultsThe average age of the participants was 29.33 ± 6.21 years. The reported average year of smoking was 5.6 ± 4.7 with the average number of 5.64 ± 5.21cigarette smoking per day. Behavioral confidence and changes in physical environment were significant predictors of smoking cessation initiation. The sustenance of smoking cessation behavior was significantly influenced by emotional transformation, practicing for change and changes in social environment.ConclusionMTM has the usefulness to assess both the initiation and sustenance behavior of smoking cessation. Potential arrangements utilizing MTM develops ought to be created in future interventions to alter behavior of smoking cessation.

BackgroundDespite increased insurance coverage since 2010, racial and ethnic minorities in the United States still receive less medical care than White counterparts. The Johns Hopkins School of Nursing’s Center for Community Programs, Innovation, and Scholarship (COMPASS Center) provides free wellness services, aiming to address healthcare disparities in the neighborhoods.ObjectiveTo delineate the types and cost of wellness services provided by the COMPASS Center.MethodsThe study employed a secondary analysis design, utilizing Qualtrics surveys to assess wellness service data from 2017 to 2022 at two main program sites—Wald center and House of Ruth, Maryland.ResultsThe analysis covered 2,194 encounters (826 at Wald center and 1,368 at House of Ruth, Maryland). Most encounters at both sites served African American/African/Black and low-income individuals. Examples of wellness services included pre-employment exams and immunizations, health literacy and self-care management education, health insurance advice, parenting support, and referrals to community resources. Cost analysis revealed varying expenses per encounter, with medium costs ranging from $5.45 to $14.91 across sites, considering service type and duration, including staff salaries, encounter numbers, and service hours.ConclusionThe COMPASS Center delivers essential wellness services supplementing traditional healthcare to disadvantaged community members through student engagement and academic support. The next generation of healthcare teams is learning with and from the community creating a holistic educational experience in building skills outside of institutional bedsides. Future plans involve structured training for students and center staff to provide wellness services, while expanding social service referrals. More work is needed to evaluate the impact of our wellness services on client satisfaction and wellness improvements.

Authors: Zhang Zhihang , An Ran , Guo Haoyan , Yang Xuanru 
Published: January 2025

Background and aimsEvidence from extensive cohort studies about the individual and combined associations of air pollution and air temperature with cardiovascular disease (CVD) morbidity is limited. This study aimed to examine the long-term effects of PM2.5 exposure and air temperature on CVD based on a cohort study of middle-aged and older populations in China.MethodsA total of 9,316 non-CVD adults (≥40 years old) who joined the China Health and Retirement Longitudinal Study between 2011 and 2018 were included in our analysis. The two-year average PM2.5 concentration and air temperature of the city where participants lived were calculated. The Cox proportional hazards model was conducted to analyze the associations of PM2.5 exposure and air temperature with CVD morbidity.ResultsIn the multivariable-adjusted model, each 10 μg/m3 rise in 2-y PM2.5 concentration was associated with an increased risk of developing CVD (hazard ratio [HR]: 1.30; 95% confidence interval [CI]: 1.27–1.32). Compared with individuals in the bearable temperature group, those with low temperatures had a higher risk of CVD (HR: 1.77; 95% CI: 1.53–2.04). Stratified analyses found that cardiovascular metabolic risk factors could not change these associations. Compared with individuals in the low-level PM2.5 exposure and bearable temperature group, those in the high-level PM2.5 exposure and low-temperature group had a 7.08 times higher risk of CVD (95% CI: 5.55–9.03).ConclusionLong-term PM2.5 exposure and low air temperature are associated with a higher risk of CVD. Consequently, efforts to reduce air pollution and enhance protection against cold temperatures are vital for mitigating CVD risk.

BackgroundThis study aimed to quantify the global impact of pneumoconiosis resulting from occupational exposure to particulate matter, gasses, and fumes from 1990 to 2021, utilizing data from the Global Burden of Disease Study 2021.MethodThe analysis evaluated the global, regional, and national burden of pneumoconiosis attributable to workplace exposure to particulate matter, gasses, and fumes. It explored variations in disease impact across different demographics, including age and gender, and analyzed the relationship between disease burden and the Socio-Demographic Index (SDI). Furthermore, an ARIMA model was employed to forecast future trends of pneumoconiosis up to 2050.ResultThe year 2021 saw pneumoconiosis from occupational particulate matter, gasses, and fumes account for roughly 4,775 deaths and 117.80 thousand disability-adjusted life years (DALYs). Over the past three decades, there was a notable decline in the disease’s burden. The condition predominantly affected males and those aged above 60. Future projections suggest a decrease in mortality rates in low to middle SDI regions, while high SDI regions may experience an increase in ASMR. Additionally, both ASMR and ASDR are anticipated to rise globally. Nationally, the Czech Republic, France, and the United States are expected to show relatively higher mortality rates in 2030 and 2050. Countries like Kazakhstan, Egypt, Mongolia, and Peru are projected to experience elevated levels of ASMR, DALY rates, and ASDR.ConclusionThe findings underscore the urgent need for policymakers to create and improve targeted preventive strategies to reduce the incidence of pneumoconiosis among specific populations.
