To investigate the association of smoking status and years since smoking cessation with the risk of incident dementia among elderly Japanese. We conducted a longitudinal analysis of smoking status and smoking cessation with dementia in prospective cohort study of 12,489 Japanese individuals aged ≥ 65 years who were followed up for 5.7 years. Information on smoking status and other lifestyle factors was collected via a questionnaire in 2006. Data on incident dementia were retrieved from the public Long-term Care Insurance Database. The Cox proportional hazards model was used to estimate the multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) for incident dementia. During 61,613 person-years of follow-up, 1110 cases (8.9%) of incident dementia were documented. Compared with individuals who had never smoked, current smokers showed a higher risk of dementia (HR 1.46, 95% CI 1.17, 1.80). Among ex-smokers, the risk for those who had stopped smoking for ≤ 2 years was still high (HR 1.39, 95% CI 0.96, 2.01), however, quitting smoking for 3 years or longer mitigated the increased risk incurred by smokers; the multivariable HRs (95% CIs) were 1.03 (0.70, 1.53) for those who had stopped smoking for 3-5 years, 1.04 (0.74, 1.45) for 6-10 years, 1.19 (0.84, 1.69) for 11-15 years, and 0.92 (0.73, 1.15) for > 15 years. Our study suggests that the risk of incident dementia among ex-smokers becomes the same level as that of never smokers if they maintain abstinence from smoking for at least 3 years.Self-reported HIV risk perception and behaviors are used in a variety of settings for diverse purposes, such as HIV prevention program planning and screening. Careful consideration of how youth in high HIV prevalence areas interpret these kinds of questions warrants attention. The Cognitive Interviewing Project (CIP) conducted cognitive interviews on common risk survey items with 30 cis-female and 20 MSM youth (18 to 24), who had recent sex with a male partner, in Cape Town and Vulindlela, South Africa. Results identified a number of potential issues including (1) confusing text; (2) mismatches of terms with local usage; (3) confusion with items requiring self-tailoring; (4) presentation concerns limiting selection of full range of answers; and (5) challenges reporting on information dependent on partner (eg., HIV risk, HIV status of partner). Self-report Items used to identify those at elevated risk for HIV should be evaluated with local populations to optimize shared understanding.Over 90% of suicides in the West could be diagnosed with mental disorders, while only 50-70% of Chinese suicides had mental disorders. Using data from a case-control study on suicide attempt, we aimed to compare characteristics and risk factors between suicide attempters with and without mental disorders. Demographic and social psychological characteristics were compared between attempters with and without mental disorders. 19.1% of the suicide attempters were diagnosed with mental disorders. Suicide attempters with mental disorders endured more strain than those without.  https://www.selleckchem.com/products/GDC-0449.html  Strain was an independent risk factor for suicide attempt among people without mental disorders. Psychological strain might be an important reason for both mental disorders and following suicide attempt. More efforts on suicide prevention should be spent on people without mental disorders. The impact of social psychological factors, such as religion, negative life events, and psychological strains should be considered.In response to a need for healthy, affordable food, Johns Hopkins Center for American Indian Health and three rural indigenous communities launched the "Feast for the Future," (FFF) to promote access to healthy foods and the transfer of traditional food-based knowledge from farmers/elders to youth. To assess program impact, 43 in-depth interviews were conducted with participating farmers, elders, and Community Advisory Board members. Interviews were recorded, transcribed, and analyzed in Atlas.ti. Common themes from qualitative analyses included FFF programs support farming/gardening revitalization and cultural connectedness/identity; FFF has supported positive behavior change among interviewees and their families; There is a need to revitalize traditional food systems; Farming/gardening is central to cultural identity; and Responsibility for food choices. The interviews revealed that the community-based program is perceived by key stakeholders as reaffirming cultural identity and promoting healthy eating. As a CAB member shared.The original version of this article unfortunately contained a mistake.

An aerosol dose collection (ADC) system was designed to uniformly deposit the whole impactor stage mass (ISM) over a large filter area for dissolution testing. All dissolution tests were performed under sink conditions in a sodium phosphate buffered saline solution containing 0.2%w/w sodium dodecyl sulphate. An adapted USP Apparatus V, Paddle over Disk (POD), was used throughout the study. The dissolution characteristics of the ISM dose of a commercial metered-dose inhaler (MDI) and a range of dry powder inhaler (DPI) formulations containing inhaled corticosteroids were tested. The uniform distribution of the validated ISM dose considerably reduced drug loading effects on the dissolution profiles for both MDI and DPI formulations. The improvement in the robustness and discriminatory capability of the technique enabled characterization of dissolution rate differences between inhaler platforms and between different DPI product strengths containing fluticasone propionate. A good correlation between in vivo mean absorption time and in vitro dissolution half-life was found for a range of the inhaled corticosteroids. The ADC system and the reproducible in vitro POD dissolution measurements provided a quantitative-based approach for measuring the relationship between the influence of device and the dispersion characteristics on the aerosol dissolution of low solubility compounds. The in vitro dissolution method could potentially be applied as a dissolution methodology for compendial, quality control release testing, and during development of both branded orally inhaled drug products and their generic counterparts.
