Method: We distributed questionnaires to 1198 mothers attending a three-month postnatal health check-up in rural areas in Japan. The questionnaires assessed these three variables along with demographics. We evaluated the causal relationships by comparing different structural equation models to the data. Results: Although all the models fit the data well, the best Akaike Information Criterion was obtained from a model where both depressive mood and bonding failure predict abusive parenting, but depressive mood and bonding failure do not predict each other directly. The determinant coefficient of child abuse in the final model was 0.13. Discussion: We found depressive mood and bonding failure during postpartum period impacted negatively on mother’s parenting behaviour. Because only 13% of the variance of abusive parenting was explainable by this model, further study should be needed to identify other risk factors of child abuse. Similarly, midwives and public health nurse in community should pay attention to not only depression but also bonding failure to prevent child abuse.展开更多

This study aimed to enhance user security to create a safe online environment by eliminating hate speech and abusive language. The proposed system employed a multifaceted approach to comment filtering, incorporating the multi-level filter theory. This involved developing a comprehensive list of words representing various types of offensive language, from slang to explicit abuse. Machine learning models were trained to identify abusive messages through sentiment analysis and contextual understanding. The system categorized comments as positive, negative, or abusive using sentiment analysis algorithms. Employing AI technology, it created a dynamic filtering mechanism that adapted to evolving online language and abusive behavior. Integrated with Instagram while adhering to ethical data collection principles, the platform sought to promote a clean and positive user experience, encouraging users to focus on non-abusive communication. Our machine-learned models, trained on a cleaned Arabic language dataset, demonstrated promising accuracy (75.8%) in classifying Arabic comments, potentially reducing abusive content significantly. This advancement aimed to provide users with a clean and positive online experience.展开更多

We draw on self-determination theory to propose that abusive supervision leads to subordinates＇ hidden destructive behavior, namely neglect. This study examines the relationship by focusing on a three way interaction model. Using multi-wave design, we collected data in a Chinese leading petrochemical corporation. We found positive associations between abusive supervision and neglect. Such associations are influenced by subordinates＇ insider status and organizational support. Theoretical and practical implications, limitations and future research directions are discussed.展开更多

文摘Objectives:To evaluate the occurrence of depression and its related factors among public health nurses(PHNs)engaged in child neglect-related abuse cases.Methods:A cross-sectional study of PHNs involved in maternal and child health or child and family welfare,and engaged in cases of child neglect-related abuse was conducted from January to March 2023 in all municipalities of 13 prefectures selected from Japan's seven regions,considering geographic diversity and major urban areas.The Patient Health Questionnaire-2 was used to screen for depression.Statistical analyses included the Chi-square test,Mann-Whitney U test,and logistic regression analysis.Results:A total of 359 provided valid responses.Among them,11.4%screened positive for depression.Significant individual factors related depression were management-stage nurses(OR=6.27,95%CI:1.63-24.18),no disability welfare experience(OR=3.49,95%CI:1.05-11.55),being assignment of highrisk cases within the past year(OR=8.28,95%CI:2.07-33.08),and lower work control(OR=0.53,95%CI:0.32-0.86).Workplace environment factors were lower perceptions and relationships within the workplace(OR=0.43,95%CI:0.29-0.65)and perceiving manpower as not secured(OR=9.07,95%CI:1.17-70.40),Conclusions:Mental health measures for PHNs should include workload management and reduced burdens through workforce enhancement,attention to burdens on managerial PHNs,promoting communication and mutual support,and opportunities to engage in disability welfare work.
文摘Heart failure(HF)is a growing public health concern,with an increasing inci-dence among younger populations.Traditionally,HF was considered a condition primarily affecting the elderly,but of late,emerging evidence hints at a rapidly rising HF incidence in youth in the past 2 decades.HF in youth has been linked to a complex interaction between emerging risk factors,such as metabolic syndrome,environmental exposures,genetic predispositions,and lifestyle behaviors.This review examines these evolving determinants,including substance abuse,autoim-mune diseases,and the long-term cardiovascular effects of coronavirus disease 2019,which disproportionately affect younger individuals.Through a compre-hensive analysis,the study highlights the importance of early detection,targeted prevention strategies,and multidisciplinary management approaches to address this alarming trend.Promoting awareness and integrating age-specific interven-tions could significantly reduce the burden of HF and improve long-term out-comes among younger populations.
文摘BACKGROUND The coronavirus disease 2019(COVID-19)pandemic had a profound societal impact in the United States which was associated with a decrease in overall life expectancy and an increase in substance abuse and firearm injury.Our under-standing of changes in mortality trends during the pandemic and its effect on organ availability for transplantation is limited.AIM To examine the trends of substance abuse and firearm injury fatalities during COVID-19 and a potential correlation with organ transplantation.METHODS Crude rates of population-based deaths among adults(18-75 years)from firearm injury and substance abuse from the period of 2014-2021 were obtained from centers of disease control wide-ranging online data for epidemiologic research database.Crude rates of causes of donor(18-75 years)deaths from 2014-2021 were obtained from the united network for organ sharing database.RESULTS Average annual percentage change(AAPC)deaths among the United States population were 16.4%from substance abuse and 3.4%from firearm injury.AAPC in cause of death among organ donors was 10.9%from drug intoxication and 2.1%from firearm injury.There was a significant(P<0.001)and progressive increase in mortality from both causes during the pandemic(2020-2021)and significant correlation(P<0.001)between population and donor causes of death.COVID-19 exacerbated trends in substance abuse and firearm mortality with a consequent increase in organ donation from donors who died from these two causes.CONCLUSION Identifying the socioeconomic and regional disparities associated with increase in deaths from substance abuse and firearms can help guide post-pandemic healthcare policies and mitigate their impact on organ transplantation.
文摘BACKGROUND Several conditions may present with acute neurological symptoms,thus mimicking the presentation of stroke.Although the underlying disorder can be diagnosed after careful medical,neurological,and radiological examinations,a few conditions,such as Wernicke encephalopathy(WE),may present a particular diagnostic difficulty.WE is a neurological disorder caused by deficiency of thiamine(B1 vitamin),most often resulting from alcoholism,malnutrition,hyperemesis gravidarum or bariatric surgery.The diagnosis of WE in a certain historical,clinical setting is easily suggested,but in a few cases presenting with acute neurological deficits,it can be particularly challenging.CASE SUMMARY We present the case of a 63-year-old man who was brought to the emergency department after developing weakness of the left extremities,dizziness and a confusional state,which had lasted for approximately 30 minutes.The patient had a similar episode of a confusional state approximately two months earlier;at that time,a transient ischemic attack was suspected and he was started on aspirin.The initial clinical evaluation and imaging findings were unremarkable for stroke,but the patient’s symptoms,history of chronic alcohol abuse and abnormal liver function tests prompted the consideration of WE.Magnetic resonance imaging findings in subthalamic areas and electroencephalogram data of diffuse delta activity supported this diagnosis.CONCLUSION Through this case report,we aim to underscore the importance of considering WE as a differential diagnosis in patients presenting with symptoms suggestive of stroke,especially when the presentation is atypical or when risk factors for thiamine deficiency are present.Since intravenous thiamine significantly improves outcomes,delayed recognition and treatment in some cases might be deleterious.

文摘Metformin is generally safe but can cause lactic acidosis and rarely organ dysfunction during overdose.Misuse for weight loss,especially in undiagnosed eating disorder,is concerning.In stigmatized settings such conditions may go unrecognized This case illustrated severe complications from chronic metformin abuse in a young female with suspected anorexia nervosa,highlighting the need for integrated medical and psychiatric care.To the best of our knowledge,this is only the second case report of multiple organ dysfunction syndrome(MODS)due to metformin toxicity.CASE SUMMARY Here,we reported a rare case of MODS involving four organs due to metformin abuse.A 22-year-old female located in Syria with a history suspicious of anorexia nervosa presented with dehydration,diarrhea,and altered consciousness.Labs revealed mixed high and normal anion gap metabolic acidosis from starvation ketosis and bicarbonate loss.She recovered with supportive care but returned 3 months later in shock with severe acidemia,kidney injury,pancreatitis,and liver dysfunction,consistent with MODS.Further history revealed chronic metformin abuse(up to 3000 mg/day)for weight loss.She recovered fully and began cognitive behavioral therapy.This case underscored the dangers of metformin misuse in eating disorders.CONCLUSION This case highlighted the potentially life-threatening consequences of surreptitious metformin abuse in the context of an underlying eating disorder.Early recognition,thorough history-taking,and multidisciplinary management,including psychiatric support,are essential for recovery and prevention of recurrence.

文摘Rape bee pollen has attracted increasing interests for its excellent protective effect against chemicalinduced liver injury owing to its abundant polyphenols.This study aims to analyze the types and contents of phenolamides(seldom concerned)in rape bee pollen and their protective mechanism on alcoholic liver disease(ALD).Different from the previous finding that flavonoids are dominant polyphenols in bee pollen polyphenolic extract,our results demonstrated that there are only three flavonoids but 24 phenolamides in the as-prepared rape bee pollen phenolic extract(PPE).In addition,PPE was found to significantly improve the viability(from 54.9%to 84.1%,89.2%,and 94.0%)of alcohol-induced AML12 cells and alleviate alcoholinduced cell apoptosis(from 28.5%to 22.89%,22.0%,and 17.4%).To dissect the underlying mechanism for the protective effect of PPE against ALD,the molecular pathway was identified by RNA-Seq analysis.Transcriptome data revealed that PPE may protect against ALD by decreasing inflammation,cholesterol,and fatty acid synthesis(P<0.05).The National Institute on Alcohol Abuse and Alcoholism(NIAAA)model was used to further evaluate the hepatoprotective effect of PPE in vivo,and the results validated that PPE could alleviate liver injury and hepatic steatosis(from 22.7%to 11.5%and 10.9%)induced by alcohol.As the dominant polyphenols in PPE,phenolamides can be a class of valuable polyphenolic compounds in bee pollen with the potential to alleviate ALD.
