童年期不良经历(ACEs)作为一项全球性的严峻公共卫生挑战,其对全生命周期的健康影响不容小觑。因此本文从心理健康、生理健康、性传播疾病及危险性行为、健康危险行为4个方面对ACEs的健康影响进行综述,为ACEs及其可能健康结局提供参考。     

Dietary Practices After Primary Treatment for Ovarian Cancer: A Qualitative Analysis From the OPAL Study

BackgroundLittle is known about the dietary practices of women who have completed primary treatment for ovarian cancer, many of whom will go on to have cancer recurrence and further treatment. Knowledge of dietary practices is needed to optimize care.ObjectiveOur aim was to identify dietary practices after primary treatment for ovarian cancer and evaluate how these practices differ by disease recurrence and treatment status.DesignWomen with invasive epithelial ovarian cancer were provided with the following open-ended question after completing a food frequency questionnaire: “Is there anything we haven’t asked you about your diet in the last 1 to 2 months that you feel is important?”Participants/settingParticipants were from the OPAL (Ovarian Cancer Prognosis and Lifestyle) Study in Australia.Main outcomesThe main outcomes were dietary practices after primary treatment for ovarian cancer and factors affecting these practices.AnalysisParticipants’ responses were analyzed using content analysis. Individual content codes were categorized and reported by recurrence and treatment status at questionnaire completion.ResultsTwo hundred eighty-six women provided responses on 363 questionnaires. Those undergoing further treatment for recurrence commonly reported dietary regimens with clinical indications (eg, low fiber to avoid bowel obstructions, high energy/protein to minimize nutritional deficits). Those not undergoing further treatment frequently reported “popular” diets (eg, organic, plant-based, and alkaline). For women with cancer recurrence, dietary practices were affected by poor appetite and late effects of treatment. For women without recurrence, other comorbidities, geographical location, family, and friends appeared to influence dietary practices. In both groups, nutrition information sources and personal beliefs informed dietary practices. Participant responses that referenced media or online sources often included misinformation.ConclusionsAfter primary treatment for ovarian cancer, women report dietary practices that may not be captured in standard food frequency questionnaires. Dietary practices and factors affecting these practices likely differ by treatment and recurrence status. Improved access to evidence-based dietary information and support is needed.     

Evaluating the impact of a targeted brief HIV intervention on multiple inter-related HIV risk factors of knowledge and attitudes among incarcerated drug users

Increases in HIV prevalence indicate ongoing need for HIV interventions. A brief manualized intervention called the Texas Christian University (TCU) WaySafe, which addresses multiple HIV risks, was further evaluated to determine how it addressed individual’s knowledge deficiencies in the assessed risks. The sample of 1,256 offenders in eight correctional substance abuse treatment programs participated either in treatment as usual (TAU) or TCU WaySafe. From multivariate multilevel analysis, WaySafe was more effective in improving the greatest need area, whether knowledge, motivation, or confidence regarding HIV risky behaviors. Findings underscored the importance of addressing HIV risk areas with the greatest need for change and strengthens previous findings of the intervention’s potential for individuals with varying HIV risks.     

Frequency of suicidal ideation and associated clinical features in Lewy body dementia

IntroductionNeuropsychiatric disturbance is common in individuals with Lewy body dementia (LBD). Despite this, there is minimal research regarding suicide risks in this population.MethodsThis study was a retrospective review of a prospectively-collected database at a tertiary movement disorders clinic. Database participants with an LBD diagnosis at their most recent visit and at least one complete Beck Depression Inventory-II (BDI-II) were included. Additional measures included demographics and measures of cognition, psychiatric symptoms, motor function, and the Parkinson Disease Questionnaire-39. The frequency of suicidal ideation was assessed using question 9 of the BDI-II. Features associated with a BDI-II score greater than zero were assessed using logistic regression.ResultsThe database included 95 individuals with LBD and at least one BDI-II (visit years 2010–2020). Most participants were older men who identified as white. Eighteen individuals (18.9%; 95% CI 12.3%–28.0%) reported thoughts of killing themselves without an intent to carry them out (BDI-II = 1). No participants reported a desire or plan to kill themselves. The presence of SI was associated with measures of depression, anxiety, and emotional well-being, but not with demographics, measures of disease severity, or other psychiatric concerns.ConclusionThese findings emphasize the importance of routine screening for psychiatric symptoms in LBD and intervention when such concerns are identified. Interventions could include pharmacologic (e.g. depression treatment) and non-pharmacologic (e.g. firearm screening) approaches. More research is needed to assess suicidal ideation and suicide risks in large and more diverse LBD populations. Prospective studies should include measures of additional potential contributors to suicidality.

Increasing Ebola transmission behaviors 6 months post-vaccination: Comparing vaccinated and unvaccinated populations near 2018 Mbandaka Ebola outbreak in the Democratic Republic of Congo

BackgroundIn 2018, the Democratic Republic of the Congo (DRC) declared its 9th and 10th Zaire ebolavirus (EBOV) outbreaks, in the Equateur province (end: July 2018), and in the eastern provinces including North Kivu (end: June 2020). The DRC Ministry of Health deployed the rVSV-vectored glycoprotein (VSV-EBOV) vaccine in response during both outbreaks.MethodsA cohort of vaccinated and unvaccinated individuals from the Equateur province were enrolled and followed prospectively for 6 months. Among participants included in this analysis, 505 were vaccinated and 1,418 were unvaccinated. Differences in transmission behaviors pre- and post- outbreak were identified, along with associations between behaviors and vaccination.ResultsThere was an overall increase in the proportion of both unvaccinated and vaccinated individuals in Mbandaka who participated in risky activities post-outbreak. Travel outside of the province pre-outbreak was associated with vaccination. Post-outbreak, vaccinated individuals were less likely to participate in funeral traditions than unvaccinated individuals.ConclusionA net increase in activities considered high risk was observed in both groups despite significant efforts to inform the population of risky behaviors. The absence of a reduction in transmission behavior post-outbreak should be considered for improving future behavior change campaigns in order to prevent recurrent outbreaks.
