The effect of physical barriers under a raised house on mosquito entry: an experimental study in rural Gambia.

BACKGROUND: Anopheles gambiae, the major malaria mosquito in sub-Saharan Africa, feed largely indoors at night. Raising a house off the ground with no barriers underneath reduces mosquito-house entry. This experiment tested whether walling off the space under an elevated hut affects mosquito-hut entry. METHODS: Four inhabited experimental huts, each of which could be moved up and down, were used in rural Gambia. Nightly collections of mosquitoes were made using light traps and temperature and carbon dioxide levels monitored indoors and outdoors using loggers. Each night, a reference hut was kept at ground level and three huts raised 2 m above the ground; with the space under the hut left open, walled with air-permeable walls or solid walls. Treatments were rotated every four nights using a randomized block design. The experiment was conducted for 32 nights. Primary measurements were mosquito numbers and indoor temperature in each hut. RESULTS: A total of 1,259 female Anopheles gambiae sensu lato were collected in the hut at ground level, 655 in the hut with an open ground floor, 981 in the hut with air-permeable walls underneath and 873 in the hut with solid walls underneath. Multivariate analysis, adjusting for confounders, showed that a raised hut open underneath had 53% fewer mosquitoes (95% CI 47-58%), those with air-permeable walls underneath 24% fewer (95% CI 9-36%) and huts with solid walls underneath 31% fewer (95% CI 24-37%) compared with a hut on the ground. Similar results were found for Mansonia spp. and total number of female mosquitoes, but not for Culex mosquitoes where hut entry was unaffected by height or barriers. Indoor temperature and carbon dioxide levels were similar in all huts. CONCLUSION: Raising a house 2 m from the ground reduces the entry of An. gambiae and Mansonia mosquitoes, but not Culex species. The protective effect of height is reduced if the space underneath the hut is walled off.

Supporting Stabilization: A Qualitative Evaluation of a Pilot Program to Integrate Personal Caregiving Services Into Housing Settings.

Three organizations in Clark County, WA, partnered together to implement a pilot program to expand access to personal caregiving services in the homeless crisis response system. The aim of this study is to describe staff and clients' experiences of the program and its impact on clients' daily living activities, health and wellbeing, and housing stability. Using a qualitative descriptive design, semi-structured, in-depth interviews were conducted with 12 clients and 5 pilot staff, representing 4 housing service providers. Interviews were analyzed descriptively to examine staff and clients' perspectives and experiences with the personal care services pilot program. Caregivers helped clients establish routines, find companionship, and connect to health and social services both logistically and socioemotionally, supporting clients' stabilization and reducing barriers to healthcare. Hiring and retaining caregivers remained difficult due to the challenging nature of the work. Staff interviews highlight the need for additional supports to better retain caregivers. Findings from the evaluation have important implications for addressing the needs of individuals exiting homelessness and suggest that personal caregivers can play an important role in supporting the stabilization process. However, employing strategies such as training and increasing wages and benefits that support the needs of the caregiving workforce is essential to sustain this type of service delivery model.

Mental Health Impact of Bullying by Ethnic Peers in Senior Housing: A Study with Older Korean American Residents in the Greater Los Angeles Area.

Using data from Korean-American residents (N = 343) in subsidized senior housing in the Los Angeles area, we examined the effect of peer bullying on mental health. About 18% of the sample had been a target of bullying, and over 31% had witnessed someone being bullied. Being a target of bullying was a significant predictor for both depressive symptoms and anxiety, whereas witnessing other residents being bullied was a significant predictor for anxiety only. Findings shed light on the adverse mental health impacts of peer bullying among ethnic minority older residents in senior housing.

'Everywhere I call, there's nothing available': Understanding the alcohol treatment landscape and needs among unstably housed people who use alcohol in Rhode Island.

INTRODUCTION: Alcohol is a leading cause of morbidity and mortality in the United States and people who are unstably housed are disproportionately impacted by adverse alcohol-related health outcomes. Addressing the needs of unstably housed people with high-intensity alcohol use (i.e., heavy episodic use or binge drinking), including those whose goal is not abstinence, is critical to reducing harms among this population. This study explores the alcohol-related treatment and support needs among unstably housed people who use alcohol. METHODS: Data collection included participant observation and semi-structured interviews (n = 25) with unstably housed people with high-intensity alcohol use. Data were analysed thematically, with attention to structural vulnerability and social-structural forces at shaping perceptions of and experiences with alcohol treatment. RESULTS: Participants underscored how housing instability was critical in precipitating and maintaining heavy alcohol use, with alcohol often used to manage the stress and anxiety related to housing instability. While participants regularly engaged with alcohol treatment programs, program design and barriers to access undermined the effectiveness of these services for participants. Participants described the need for a range of program and service options across a continuum of care to be implemented to support participants in meeting their diverse needs and identified goals regarding alcohol use. DISCUSSION AND CONCLUSIONS: Alcohol treatment and supports need to be modified so that they include a range of harm reduction and abstinence-based models to better meet people's diverse needs. Furthermore, treatment must be paired with permanent and affordable housing to address underlying drivers of alcohol-related harm for unstably housed people.

Do Medicaid Expenditures Increase After Adults Exit Permanent Supportive Housing?

The effects of homelessness and permanent supportive housing (PSH) on health care utilization have been well documented. Prior research on the association between PSH entry and Medicaid expenditures have indicated that such housing support could result in savings to Medicaid programs; however, whether changes occur in health care use and expenditures after individuals exit PSH is unknown. If efficiency gains from PSH persist after the individual leaves PSH, the savings to payers such as Medicaid may continue even after the costs to provide housing for a PSH recipient have ended. We used linked Medicaid and housing data from Pennsylvania to examine changes in the level and composition of Medicaid expenditures for 580 adult enrollees during the 12 months before and after exit from PSH adjusting for relevant covariates. In adjusted analyses, we estimated that monthly spending declined by $200.32 (95% CI: $323.50, $75.15) in the first quarter post-exit and by $267.63 (95% CI: $406.10, $127.10) in the third quarter. Our findings suggest that PSH may have sustained budgetary benefits to state Medicaid agencies even for beneficiaries exiting the program. However, more research is needed to understand if these reductions in expenditures last beyond 12 months and do not reflect under-use of care that may be important for managing health over the long-term.

The impact of housing prices on residents' health: a systematic review.

BACKGROUND: Rising housing prices are becoming a top public health priority and are an emerging concern for policy makers and community leaders. This report reviews and synthesizes evidence examining the association between changes in housing price and health outcomes. METHODS: We conducted a systematic literature review by searching the SCOPUS and PubMed databases for keywords related to housing price and health. Articles were screened by two reviewers for eligibility, which restricted inclusion to original research articles measuring changes in housing prices and health outcomes, published prior to June 31st, 2022. RESULTS: Among 23 eligible studies, we found that changes in housing prices were heterogeneously associated with physical and mental health outcomes, with multiple mechanisms contributing to both positive and negative health outcomes. Income-level and home-ownership status were identified as key moderators, with lower-income individuals and renters experience negative health consequences from rising housing prices. This may have resulted from increased stress and financial strain among these groups. Meanwhile, the economic benefits of rising housing prices were seen to support health for higher-income individuals and homeowners - potentially due to increased wealth or perception of wealth. CONCLUSIONS: Based on the associations identified in this review, it appears that potential gains to health associated with rising housing prices are inequitably distributed. Housing policies should consider the health inequities born by renters and low-income individuals. Further research should explore mechanisms and interventions to reduce uneven economic impacts on health.

Impacts of longitudinal water curtain cooling system on transcriptome-related immunity in ducks.

BACKGROUND: The closed poultry houses integrated with a longitudinal water curtain cooling system (LWCCS) are widely used in modern poultry production. This study showed the variations in environmental conditions in closed houses integrated with a longitudinal water curtain cooling system. We evaluated the influence of different environmental conditions on duck growth performance and the transcriptome changes of immune organs, including the bursa of Fabricius and the spleen. RESULT: This study investigated the slaughter indicators and immune organ transcriptomes of 52-day-old Cherry Valley ducks by analyzing the LWCC at different locations (water curtain end, middle position, and fan cooling end). The results showed that the cooling effect of the LWCCS was more evident from 10:00 a.m. -14:00. And from the water curtain end to the fan cooling end, the hourly average temperature differently decreased by 0.310℃, 0.450℃, 0.480℃, 0.520℃, and 0.410℃, respectively (P < 0.05). The daily and hourly average relative humidity decreased from the water curtain end to the fan cooling end, dropping by 7.500% and 8.200%, respectively (P < 0.01). We also observed differences in production performance, such as dressing weight, half-eviscerated weight, skin fat rate, and percentage of abdominal fat (P < 0.01), which may have been caused by environmental conditions. RNA-sequencing (RNA-seq) revealed 211 and 279 differentially expressed genes (DEGs) in the ducks' bursa of Fabricius and spleen compared between the water curtain end and fan cooling end, respectively. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis of the two organs showed the DEGs were mainly enriched in cytokine-cytokine receptor interaction, integral component of membrane, Retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) signaling pathway, etc. Our results implied that full-closed poultry houses integrated with LWCCS could potentially alter micro-environments (water curtain vs. fan cooling), resulting in ducks experiencing various stressful situations that eventually affect their immunity and production performance. CONCLUSION: In this study, our results indicated that uneven distributions of longitudinal environmental factors caused by LWCCS would affect the dressed weight, breast muscle weight, skin fat rate, and other product performance. Moreover, the expression of immune-related genes in the spleen and bursa of ducks could be affected by the LWCCS. This provides a new reference to optimize the use of LWCCS in conjunction with close duck houses in practical production.

Housing debt and depressive symptoms: evidence from the China family panel studies.

BACKGROUND: There is limited evidence on the association between housing debt and depressive symptoms in China. This study aimed to examine the impact of housing debt on depressive symptoms and explore the heterogeneous impacts arising from two sources of housing debt and two types of housing demands. METHODS: Using data from the 2016 and 2018 China Family Panel Studies (CFPS), this study included 25,232 Chinese individuals. Depressive symptoms were assessed using the eight-item Center for Epidemiological Studies Depression Scale (CES-D8). Housing debt was measured by dummy variables, indicating whether an individual had housing debt, and continuous variables, which were the logarithm of the total amount of housing debt. The two-way fixed effects model was used to examine the relationship. RESULTS: Housing debt had a significant positive impact on depressive symptoms in China. Individuals with housing debt had a 0.176-point higher depressive symptom score than those without housing debt. A 10% increase in the total amount of housing debt led to a 0.16-point increase in depressive symptoms. Non-bank housing loans significantly increased the level of depressive symptoms with a larger coefficient (coef = 0.289), while the impact of bank housing loans was small and not statistically significant. In terms of the types of housing demands, a positive impact was observed only among individuals who had only one property meeting their housing consumption demands. CONCLUSIONS: This study found a significant positive impact of housing debt on depressive symptoms, primarily driven by non-bank housing loans. Furthermore, housing debt increased the depressive symptoms among individuals with consumption demands, while those with investment demands did not show a significant impact. Government interventions should prioritize easing formal financial constraints and providing support for individuals with housing consumption demands.

Disparities in the Quality of Working Life Among Older Workers: Housing Conditions and Life Satisfaction With Latent Class Analysis.

Little empirical research informs understanding of the disparate active aging experiences among working older adults, especially in terms of the association with living circumstances and life satisfaction. To address this knowledge gap, this study used latent class analysis on data from the 2020 Health and Retirement Study (HRS) core interview and focused on 1,194 employed adults aged 50 and above. The results revealed four subtypes of the quality of working life in older workers. Notably, in contrast to the other identified classes, higher levels of housing satisfaction and feelings of neighborhood safety were significantly associated with an increased likelihood of being a member of the group of older adults with the highest work capacities and the healthy work-life balance. Furthermore, participation in the class characterized by the highest work capacity and a healthy work-life balance was related to the highest levels of overall life satisfaction.

Healthcare Access Worsened for Women in Precarious Housing During the COVID-19 Pandemic: A Qualitative Study.

This research aims to gain an in-depth understanding of precariously housed women's experiences related to health and access to health care during the COVID-19 pandemic using a grounded theory approach. Qualitative data were obtained through interviews with 17 precariously housed women from Izmir, Turkey. Poor health among most participants was primarily attributed to unfavorable living conditions and weakened community networks. The COVID-19 pandemic exacerbated existing health issues due to barriers in accessing basic needs. Food insecurity was widespread during the pandemic and the critical role of aid and the inadequacy of social assistance in securing food were emphasized. Women's health perceptions were significantly shaped by gender, and gendered caregiving duties have restricted women's healthcare access. Access to healthcare was also limited by financial challenges, with health insurance being a crucial determinant. Longer waiting times, often exacerbated by the appointment system, and language were significant barriers to healthcare access. The findings propose that the participants were precarized by the blindness of COVID-19 measures to vulnerabilities, which resulted in deeper inequalities in housing, food, employment, and healthcare access. This research addresses the political, commercial, and social determinants of precariously housed women's health. Improving precariously housed women's health and wellbeing requires implementation of public policies targeting to improve housing quality, provide targeted assistance to food insecurity, promote gender inclusiveness, and foster gender empowerment.

Health effects of holistic housing renovation in a disadvantaged neighbourhood in the Netherlands: a qualitative exploration among residents and professionals.

BACKGROUND: Holistic housing renovations combine physical housing improvements with social and socioeconomic interventions (e.g. referral to social services, debt counselling, involvement in decision-making, promoting social cohesion). In a deprived neighbourhood in Utrecht, the Netherlands, this paper examined residents' and professionals' experiences, ideas, and perceptions regarding holistic housing renovation, its health effects, and underlying mechanisms explaining those effects. METHODS: Semi-structured in-depth interviews were conducted with 21 social housing residents exposed to holistic housing renovation, and 12 professionals involved in either the physical renovation or social interventions implemented. Residents were interviewed in various renovation stages (before, during, after renovation). Transcripts were deductively and inductively coded using qualitative software. RESULTS: Residents experienced and professionals acknowledged renovation stress caused by nuisance from construction work (noise, dust), having to move stuff around, and temporary moving; lack of information and control; and perceived violation of privacy. Involvement in design choices was appreciated, and mental health improvement was expected on the long term due to improved housing quality and visual amenity benefits. Social contact between residents increased as the renovation became topic for small talk. Few comments were made regarding physical health effects. The interviews revealed a certain amount of distrust in and dissatisfaction with the housing corporation, construction company, and other authorities. CONCLUSIONS: Renovation stress, aggravated by lack of information and poor accessibility of housing corporation and construction company, negatively affects mental health and sense of control. Potential stress relievers are practical help with packing and moving furniture, and increased predictability by good and targeted communication. Social interventions can best be offered after renovation, when residents live in their renovated apartment and the nuisance and stress from the renovation is behind them. Social partners can use the period leading up to the renovation to show their faces, offer practical help to reduce renovation stress, and increase residents' trust in their organization and authorities in general. This might also contribute to residents' willingness to accept help with problems in the social domain after renovation.

Risk factors for food insecurity and association with prenatal care utilization among women who took opioids during pregnancy.

Background: Food insecurity during pregnancy is associated with poorer outcomes for both mothers and their newborns. Given the ongoing opioid crisis in the United States, mothers who take opioids during pregnancy may be at particular risk of experiencing food insecurity. Methods: This research utilized data from 254 biological mothers of infants in the Advancing Clinical Trials in Neonatal Opioid Withdrawal Syndrome (ACT NOW) Outcomes of Babies with Opioid Exposure (OBOE) Study. We examined factors associated with food insecurity among mothers of infants with antenatal opioid exposure and their unexposed (control) counterparts. Chi-square tests and logistic regression were used to compare food insecurity by sociodemographic characteristics, opioid use, prior traumatic experiences, and housing instability. Similar analyses were conducted to examine the relationship between food insecurity during pregnancy and receipt of adequate prenatal care. Results: Overall, 58 (23%) of the mothers screened positive for food insecurity. Food insecurity was more common among mothers who took opioids during pregnancy (28% vs. 14%; p =0.007), had public insurance (25% vs. 8%; p = 0.027), had housing instability (28% vs. 11%, p = 0.002), experienced three or more adverse experiences in their childhood (37% vs. 17%; p < 0.001), and reported physical or emotional abuse during their pregnancy (44% vs. 17%; p < 0.001). Mothers with food insecurity during pregnancy were less likely to have received adequate prenatal care (78% vs. 90%; p = 0.020). This difference remained after controlling for demographic characteristics (AOR (95% CI) = 0.39 (0.16, 1.00), p = 0.049). Conclusions: This study adds to the body of evidence supporting the need for screening and development of interventions to address food insecurity during pregnancy, particularly among mothers of infants with antenatal opioid exposure, for which limited data are available. The findings revealed that food insecurity frequently co-occurs with housing instability and prior trauma, indicating that a multifaceted intervention incorporating principles of trauma-informed health care is needed. Although those with food insecurity are at increased risk for poor pregnancy outcomes, they were less likely to have received adequate prenatal care despite high levels of public insurance coverage among study participants, suggesting additional strategies are needed to address barriers to health care among this population. Trial registration: The Outcomes of Babies with Opioid Exposure (OBOE) Study is registered at Clinical Trials.gov (NCT04149509) (04/11/2019).

Spatial and temporal indoor temperature differences at home and perceived coldness in winter: A cross-sectional analysis of the nationwide Smart Wellness Housing survey in Japan.

Residents themselves are responsible for controlling their living environment, and their perception of coldness is important to protect their health. Although previous studies examined the association between perceived coldness and indoor temperature, they did not consider the spatial-temporal differences in indoor temperatures. This study, conducted in Japan, measured indoor temperatures in 1,553 houses across several rooms (living room, changing room, and bedroom) and heights (at 1 m above the floor and near the floor) over two weeks and obtained the perceived coldness from 2,793 participants during winter. Results showed substantial temperature differences between rooms (horizontal differences): 3.8 °C between living and changing rooms, and 4.1 °C between living rooms and bedrooms. The average vertical and diel (evening-morning) temperature differences in the living room were 3.1 °C and 3.0 °C, respectively. Regional analysis revealed that the Tohoku region experienced larger horizontal and diel indoor temperature differences, primarily due to its practice of intermittent and partial heating in living rooms only, in contrast to Hokkaido's approach of heating the entire house continuously. Despite Hokkaido's comprehensive heating system, it exhibited the largest vertical temperature difference of 5.1 °C in living rooms, highlighting the insufficiency of heating alone and the necessity for enhanced thermal insulation. The multivariate logistic regression analyses showed that average temperatures and vertical temperature differences were associated with perceived coldness, while horizontal and diel differences did not show a significant association, further emphasizing the importance of improved thermal insulation. Moreover, factors like individual attributes (age and gender), and lifestyle choices (meal quantity, exercise habits, alcohol consumption, and clothing amount) were significantly associated with coldness perception. Notably, older adults were less likely to perceive coldness but more vulnerable to the health impacts of low temperatures, underscoring the necessity of not solely relying on human perception for indoor temperature management to protect cold-related health problems.

Biocultural and social determinants of ill health and early mortality in a New Mexican paediatric autopsy sample.

RESULTS.: Hispanic children have higher odds of growth stunting than non-Hispanic White children. Native American children die younger and have higher odds of respiratory diseases and porous lesions than Hispanic and non-Hispanic Whites. Rural/urban location does not significantly impact age at death, but housing type does. Individuals who lived in trailers/mobile homes had earlier ages at death. When intersections between housing type and housing location are considered, children who were poor and from impoverished areas lived longer than those who were poor from relatively well-off areas. CONCLUSIONS.: Children's health is shaped by factors outside their control. The children included in this study embodied experiences of social and ELS and did not survive to adulthood. They provide the most sobering example of the harm that social factors (structural racism/discrimination, socioeconomic, and political structures) can inflict.

Impact of meeting housing needs on human health.

OBJECTIVE: Aim: To identify the impact of meeting the housing needs on human health, which must be taken into account when developing the health care policy for the country's population. PATIENTS AND METHODS: Materials and Methods: The system of general scientific and special research methods was used during the research. The materials of the work were: statistical data; standards and recommendations regarding sanitary living conditions; court case-law; reports in mass media; scientific sources; regulatory legal acts of Ukraine. CONCLUSION: Conclusions: Sanitary and hygienic conditions of living in housing provide for the formation of a human life environment, where there is no harmful effect of its factors on human health and there are opportunities to ensure normal and to restore impaired body functions. Each person is responsible for maintaining own sanitary and hygienic living conditions in the housing. Sanitary and hygienic living conditions of a person must be considered through the principle of reasonableness and safety of public health.

Household Environments and Functional Decline Among Middle-Aged and Older Adults in China: Variations by Gender, Age, and Residence.

This study examined the associations between household social, economic, and physical environments and the trajectory of functional limitations over time among middle-aged and older adults in China, and how this relationship differs by gender, age, and residence. Linear growth curve models were applied to a sample of 13,564 respondents aged 45 years and older from four waves of the China Health and Retirement Longitudinal Study (CHARLS 2011-2018). Living alone, particularly for rural, female, and older respondents, was associated with a faster functional decline when compared to living with a spouse and without children. Improved housing quality was associated with a slower functional decline. Living with young descendants and without adult children for urban residents and a lower expenditure per capita for younger respondents were associated with a faster functional decline. These findings suggest that policies aimed at enhancing living conditions have the potential to improve physical functioning of older adults.

Producer perceptions of dairy calf management, behavior, and welfare.

Approaches for raising calves vary across commercial dairy farms and relate to behavioral opportunities and animal welfare. The objectives of this study were to evaluate how US dairy producers and calf managers perceive 1) welfare implications of varying management practices (including social housing and milk allowance) and behaviors in dairy calves, and 2) aspects of the human-animal relationship in calf rearing and relationships with on-farm management and personal calf handling habits. Survey questions were primarily quantitative (e.g., Likert scales) and addressed how common calf management practices and observed calf behaviors were related to aspects of welfare, including calf health and comfort. We additionally posed questions addressing respondent habits, management protocols, and perceptions related to human-animal interaction. Responses from 93 dairy producers and calf managers were collected via digital surveys. Social housing was viewed as being generally positive for both calf comfort and health, although this view was stronger with respect to calf comfort. Respondents from farms using social housing (56%) had more positive perceptions of social housing, viewed social play as being associated with better calf comfort and health, and considered access to other calves and "freedom to express natural behavior" as being more important for calves, compared with respondents from farms not providing social housing. Providing greater milk allowances (>7.6 L/d) was viewed as being good for both calf comfort and health, although respondents from farms providing these milk allowances (59%) had more positive perceptions than those who provided lesser allowances. Abnormal oral behaviors were viewed as being associated with both poor calf comfort and health. The welfare importance of various resources which may reduce abnormal oral behaviors (including hay and brushes) was perceived more ambiguously, although respondents from farms providing these resources, compared with those who do not, generally viewed them as more preferred by calves. We observed a positive relationship between how respondents perceived the human-animal bond (i.e., that calves enjoy contact with humans) and stated personal behavior related to calf contact (frequency of contacting calves to scratch or pet them). Respondent demographics were not related to perceptions of the human-animal relationship, but respondents identifying as female described more frequent positive calf interactions. Described aspects of human-animal interactions were not related to implementation of social housing on-farm. Job satisfaction was positively related to perception of the human-animal relationship. Overall, these results suggest that most calf management personnel place a high value on calf welfare, although farms implementing social housing appear to place a greater value on subjective calf well-being and individual perceptions of animal welfare may depend on practical experience.

The oxytocin receptor is essential for the protective effect of pair housing on post-stroke depression in mice.

The beneficial effect of social interaction in mitigating the incidence of post-stroke depression (PSD) and ameliorating depressive symptoms has been consistently demonstrated through preclinical and clinical studies. However, the underlying relationship with oxytocin requires further investigation. In light of this, the present study aimed to explore the protective effect of pair housing on the development of PSD and the potential relationship with oxytocin receptors. The PSD model was induced by middle cerebral artery occlusion (MCAO) for 50 min, followed by 4-week isolated housing and restrained stress. Subsequently, each mouse in the pair-housing group (PH) was pair-housed with an isosexual healthy partner. Another group was continuously administrated fluoxetine (10 mg/Kg, i.p, once a day) for 3 weeks. To elucidate the potential role of oxytocin, we subjected pair-housed PSD mice to treatment with an oxytocin receptor (OXTR) antagonist (L368,889) (5 mg/Kg, i.p, once a day) for 3 weeks. At 31 to 32 days after MCAO, anxiety- and depressive-like behaviors were assessed using sucrose consumption, forced swim test, and tail-suspension test. The results showed that pair housing significantly improved post-stroke depression to an extent comparable to that of fluoxetine treatment. Furthermore, pair housing significantly decreased corticosterone in serum, increasing OXT mRNA expression in the hypothalamus. Treatment with L368,889 essentially reversed the effect of pair housing, with no discernible sex differences apart from changes in body weight. Pair housing increased hippocampal serotonin (5-HT), but treatment with L368,889 had no significant impact. Additionally, pair housing effectively reduced the number of reactive astrocytes and increased Nissl's body in the cortex and hippocampal CA3 regions. Correspondingly, treatment with L368,889 significantly reversed the changes in the Nissl's body and reactive astrocytes. Moreover, pair housing downregulated mRNA levels of TNF-α, IL-1ß, and IL-6 in the cortex caused by PSD, which was also reversed by treatment with L368,889. In conclusion, pair housing protects against the development of PSD depending on OXT and OXTR in the brain, with no significant divergence based on sex. These findings provide valuable insights into the potential of social interaction and oxytocin as therapeutic targets for PSD. Further research into the underlying mechanisms of these effects may contribute to the development of novel treatments for PSD.

Justifying the need for a recovery related surveillance system: Exploratory focused interviews.

Background and Aims: No recovery related surveillance system exists but given the evidence of effectiveness and growing supply, a house- and resident- level recovery house (RH) surveillance system could be beneficial for data collection on recovery support service (RSS) engagement, and retention; for improved standardization of RH programs and services; and for identification of outcomes associated with long-term recovery. Methods: This study aimed to explore current data collection practices at the resident- and house- level through qualitative focus interviews of RH representatives. The 13 RH interviews were scheduled with 16 RH representative respondents. Results: The most frequently collected resident data was at entry (92%) and departure (85%) and included demographics (n = 5), substance use history (n = 6), treatment and recovery history (n = 5), legal and correctional history (n = 6) and mental health information (n = 7). Recovery support data was collected by 85% of houses. Post-stay data was only collected by four RHs (31%). Conclusion: These results indicate that there is a lack of standardized systematic collection, analysis, and reporting of recovery related data in the RH field. A recovery related surveillance system has the potential to fill this gap and inform and improve standard of resident care to support long-term recovery from substance use disorder.

Capturing the Dynamics of Homelessness Through Ethnography and Mobile Technology: Protocol for the Development and Testing of a Smartphone Technology-Supported Intervention.

BACKGROUND: US military veterans who have experienced homelessness often have high rates of housing transition. Disruptions caused by these transitions likely exacerbate this population's health problems and interfere with access to care and treatment engagement. Individuals experiencing homelessness increasingly use smartphones, contributing to improved access to medical and social services. Few studies have used smartphones as a data collection tool to systematically collect information about the daily life events that precede and contribute to housing transitions, in-the-moment emotions, behaviors, geographic movements, and perceived social support. OBJECTIVE: The study aims to develop and test a smartphone app to collect longitudinal data from veterans experiencing homelessness (VEH) and to evaluate the feasibility and acceptability of using the app in a population that is unstably housed or homeless. METHODS: This study's design had 3 phases. Phase 1 used ethnographic methods to capture detailed data on day-to-day lived experiences of up to 30 VEH on topics such as housing stability, health, and health behaviors. Phase 2 involved focus groups and usability testing to develop and refine mobile phone data collection methods. Phase 3 piloted the smartphone mobile data collection with 30 VEH. We included mobile ethnography, real-time surveys through an app, and the collection of GPS data in phase 3. RESULTS: The project was launched in June 2020, and at this point, some data collection and analysis for phases 1 and 2 are complete. This project is currently in progress. CONCLUSIONS: This multiphase study will provide rich data on the context and immediate events leading to housing transitions among VEH. This study will ensure the development of a smartphone app that will match the actual needs of VEH by involving them in the design process from the beginning. Finally, this study will offer important insights into how best to develop a smartphone app that can help intervene among VEH to reduce housing transitions.
