Food Habits of Older Australians Living Alone in the Australian Capital Territory

The link between adequate nutrition and quality of life for older persons is well established. With the proportion of older adults increasing, policy regarding support and care for the ageing has shifted emphasis to keeping older adults in their homes for as long as possible. Risk of malnutrition is an issue of importance for this population and, while this risk is well researched within the hospital setting, it is still relatively under-researched within the community-dwelling elderly, particularly with respect to the lived experience. This qualitative study (underpinned by interpretative phenomenology philosophy) explores how the lived experiences of community-dwelling older people living in one-person households in the Australian Capital Territory (ACT) influences dietary patterns, food choices and perceptions about food availability. Using purposeful and snowballing sampling, older people (65 years and over) living alone in the community participated in focus group discussions triangulated with their family/carers. Data were thematically analysed using a previously established approach. Participants (n = 22) were interviewed in three focus groups. Three themes were identified: active and meaningful community connectedness; eating well and behaviours to promote dietary resilience. Of these, community connectedness was pivotal in driving food patterns and choices and was a central component influencing behaviours to eating well and maintaining dietary resilience

Examining the Reasons for Student Responses to Threatening Behaviors on a College Campus

Underreporting criminal activity to authorities can pose significant challenges, particularly within college campuses. Crime prevention teams have recognized the importance of reporting potentially concerning behaviors that may precede violent acts. However, reasons for reporting preincident behaviors have been understudied among college samples and failed to account for informal responses, such as talking to third parties or changing personal security features. The present study surveyed 1,075 students from a midwestern state university and evaluated their awareness of threatening or concerning behaviors on campus, response behaviors, and reasons for either acting on or failing to report preincident behaviors. Findings reflected reporting rates (12.3%) consistent with the scientific literature but revealed informal responding as the most common reaction to preincident behaviors (44.6%). Reasons for not taking action included a desire to be uninvolved and perceiving the situation as unlikely to be immediately dangerous. By contrast, those who reported preincident behaviors appraised the situation as immediately dangerous and likely to result in harm.

An epilepsy-associated SV2A mutation disrupts synaptotagmin-1 expression and activity-dependent trafficking

The epilepsy-linked gene , has a number of potential roles in the synaptic vesicle (SV) life cycle. However, how loss of SV2A function translates into presynaptic dysfunction and ultimately seizure activity is still undetermined. In this study, we examined whether the first SV2A mutation identified in human disease (R383Q) could provide information regarding which SV2A-dependent events are critical in the translation to epilepsy. We utilized a molecular replacement strategy in which exogenous SV2A was expressed in mouse neuronal cultures of either sex, which had been depleted of endogenous SV2A to mimic the homozygous human condition. We found that the R383Q mutation resulted in a mislocalization of SV2A from SVs to the plasma membrane, but had no effect on its activity-dependent trafficking. This SV2A mutant displayed reduced mobility when stranded on the plasma membrane and reduced binding to its interaction partner synaptotagmin-1 (Syt1). Furthermore, the R383Q mutant failed to rescue reduced expression and dysfunctional activity-dependent trafficking of Syt1 in the absence of endogenous SV2A. This suggests that the inability to control Syt1 expression and trafficking at the presynapse may be key in the transition from loss of SV2A function to seizure activity. SV2A is a synaptic vesicle (SV) protein, the absence or dysfunction of which is linked to epilepsy. However, the series of molecular events that result in this neurological disorder is still undetermined. We demonstrate here that the first human mutation in SV2A identified in an individual with epilepsy displays reduced binding to synaptotagmin-1 (Syt1), an SV protein essential for synchronous neurotransmitter release. Furthermore, this mutant cannot correct alterations in both Syt1 expression and trafficking when expressed in the absence of endogenous SV2A (to mimic the homozygous human condition). This suggests that the inability to control Syt1 expression and trafficking may be key in the transition from loss of SV2A function to seizure activity

Association between severe drought and HIV prevention and care behaviors in Lesotho: A population-based survey 2016–2017

Background A previous analysis of the impact of drought in Africa on HIV demonstrated an 11% greater prevalence in HIV-endemic rural areas attributable to local rainfall shocks. The Lesotho Population-Based HIV Impact Assessment (LePHIA) was conducted after the severe drought of 2014–2016, allowing for reevaluation of this relationship in a setting of expanded antiretroviral coverage. Methods and findings LePHIA selected a nationally representative sample between November 2016 and May 2017. All adults aged 15–59 years in randomly selected households were invited to complete an interview and HIV testing, with one woman per household eligible to answer questions on their experience of sexual violence. Deviations in rainfall for May 2014–June 2016 were estimated using precipitation data from Climate Hazards Group InfraRed Precipitation with Station Data (CHIRPS), with drought defined as <15% of the average rainfall from 1981 to 2016. The association between drought and risk behaviors as well as HIV-related outcomes was assessed using logistic regression, incorporating complex survey weights. Analyses were stratified by age, sex, and geography (urban versus rural). All of Lesotho suffered from reduced rainfall, with regions receiving 1%–36% of their historical rainfall. Of the 12,887 interviewed participants, 93.5% (12,052) lived in areas that experienced drought, with the majority in rural areas (7,281 versus 4,771 in urban areas). Of the 835 adults living in areas without drought, 520 were in rural areas and 315 in urban. Among females 15–19 years old, living in a rural drought area was associated with early sexual debut (odds ratio [OR] 3.11, 95% confidence interval [CI] 1.43–6.74, p = 0.004), and higher HIV prevalence (OR 2.77, 95% CI 1.19–6.47, p = 0.02). It was also associated with lower educational attainment in rural females ages 15–24 years (OR 0.44, 95% CI 0.25–0.78, p = 0.005). Multivariable analysis adjusting for household wealth and sexual behavior showed that experiencing drought increased the odds of HIV infection among females 15–24 years old (adjusted OR [aOR] 1.80, 95% CI 0.96–3.39, p = 0.07), although this was not statistically significant. Migration was associated with 2-fold higher odds of HIV infection in young people (aOR 2.06, 95% CI 1.25–3.40, p = 0.006). The study was limited by the extensiveness of the drought and the small number of participants in the comparison group. Conclusions Drought in Lesotho was associated with higher HIV prevalence in girls 15–19 years old in rural areas and with lower educational attainment and riskier sexual behavior in rural females 15–24 years old. Policy-makers may consider adopting potential mechanisms to mitigate the impact of income shock from natural disasters on populations vulnerable to HIV transmission

Evidence for Circumstellar Disks around Young Brown Dwarfs in the Trapezium Cluster

We report the results of deep infrared observations of brown dwarf candidates in the Trapezium cluster in Orion. Analysis of the JHK color-color diagram indicates that a large fraction (approx 65% +/- 15%) of the observed sources exhibit infrared excess emission. This suggests the extreme youth of these objects and in turn, provides strong independent confirmation of the existence of a large population of substellar objects in the cluster. Moreover, this suggests that the majority of these substellar objects are presently surrounded by circumstellar disks similar to the situation for the stellar population of the cluster. This evidence for a high initial disk frequency (> 50%) around cluster members of all masses combined with the smooth continuity of the cluster's initial mass function across the hydrogen burning limit suggests that a single physical mechanism is likely responsible for producing the entire cluster mass spectrum down to near the deuterium burning limit. The results may also indicate that even substellar objects are capable of forming with systems of planetary companions.Comment: 6 pages, 2 figures. Accepted to ApJ Letter
