RESUMO
INTRODUCTION: Few studies have examined the impact of emergency department (ED) social interventions on patient outcomes and revisits, especially in underserved populations. Our objective in this study was to characterize a volunteer initiative that provided community medical and social resources at ED discharge and its effect on ED revisit rates and adherence to follow-up appointments at a large, county hospital ED. METHODS: We performed a cross-sectional analysis of ED patients who received medical and social resources and an educational intervention at discharge between September 2017-June 2018. Demographic information, the number of ED return visits, and outpatient follow-up appointment adherence within 30 and 90 days of ED discharge were obtained from electronic health records. We obtained data regarding patient utilization of resources via telephone follow-up communication. We used logistic regression analyses to evaluate associations between patient characteristics, reported resource utilization, and revisit outcomes. RESULTS: Most patients (55.3% of 494 participants) identified as Latino/Hispanic, and 49.4% received healthcare assistance through a local governmental program. A majority of patients (83.6%) received at least one medical or social resource, with most requesting more than one. Patients provided with a medical or social resource were associated with a higher 90-day follow-up appointment adherence (odds ratio [OR] 2.56; 95% confidence interval [CI] 1.05-6.25, and OR 4.75; 95% CI 1.49-15.20], respectively), and the provision of both resources was associated with lower odds of ED revisit within 30 days (OR 0.50; 95% CI 0.27-0.95). Males and those enrolled in the healthcare assistance program had higher odds of ED revisits, while Hispanic/Latino and Spanish-speaking patients had lower odds of revisits. CONCLUSION: An ED discharge intervention providing medical and social resources may be associated with improved follow-up adherence and reduced ED revisit rates in underserved populations.

Care for non-communicable diseases, including hypertension and diabetes (HTN/DM), is recognized as a growing challenge in humanitarian crises, particularly in low- and middle-income countries (LMICs) where most crises occur. There is little evidence to support humanitarian actors and governments in designing efficient, effective, and context-adapted models of care for HTN/DM in such settings. This article aimed to systematically review the evidence on models of care targeting people with HTN/DM affected by humanitarian crises in LMICs. A search of the MEDLINE, Embase, Global Health, Global Indexus Medicus, Web of Science, and EconLit bibliographic databases and grey literature sources was performed. Studies were selected that described models of care for HTN/DM in humanitarian crises in LMICs. We descriptively analysed and compared models of care using a conceptual framework and evaluated study quality using the Mixed Methods Appraisal Tool. We report our findings according to PRISMA guidelines. The search yielded 10 645 citations, of which 45 were eligible for this review. Quantitative methods were most commonly used (n = 34), with four qualitative, three mixed methods, and four descriptive reviews of specific care models were also included. Most studies detailed primary care facility-based services for HTN/DM, focusing on health system inputs. More limited references were made to community-based services. Health care workforce and treatment protocols were commonly described framework components, whereas few studies described patient centredness, quality of care, financing and governance, broader health policy, and sociocultural contexts. There were few programme evaluations or effectiveness studies, and only one study reported costs. Most studies were of low quality. We concluded that an increasing body of literature describing models of care for patients with HTN/DM in humanitarian crises demonstrated the development of context-adapted services but showed little evidence of impact. Our conceptual framework could be used for further research and development of NCD models of care.

INTRODUCTION: Critical care in low-income and low-middle income countries (LLMICs) is an underdeveloped component of the healthcare system. Given the increasing growth in demand for critical care services in LLMICs, understanding the current capacity to provide critical care is imperative to inform policy on service expansion. Thus, our aim is to describe the provision of critical care in LLMICs with respect to patients, providers, location of care and services and interventions delivered. METHODS AND ANALYSIS: We will search PubMed/MEDLINE, Web of Science and EMBASE for full-text original research articles available in English describing critical care services that specify the location of service delivery and describe patients and interventions. We will restrict our review to populations from LLMICs (using 2016 World Bank classifications) and published from 1 January 2008 to 1 January 2020. Two-reviewer agreement will be required for both title/abstract and full text review stages, and rate of agreement will be calculated for each stage. We will extract data regarding the location of critical care service delivery, the training of the healthcare professionals providing services, and the illnesses treated according to classification by the WHO Universal Health Coverage Compendium. ETHICS AND DISSEMINATION: Reviewed and exempted by the Stanford University Office for Human Subjects Research and IRB on 20 May 2020. The results of this review will be disseminated through scholarly publication and presentation at regional and international conferences. This review is designed to inform broader WHO, International Federation for Emergency Medicine and partner efforts to strengthen critical care globally. PROSPERO REGISTRATION NUMBER: CRD42019146802.

OBJECTIVE: Injuries resulting from road traffic crashes are a major and growing public health problem worldwide, disproportionately affecting vulnerable road users in developing countries. However, research on road traffic injuries in developing countries has been limited. We studied road traffic injuries among middle school students in a rural area of China. METHODS: We surveyed 1551 students in Hunan province using a hard-copy survey questionnaire. The survey was conducted at two middle schools with the cooperation of teachers and school officials. The questionnaire gathered data including sociodemographics, school activities, and sleep patterns along with road traffic injuries among middle students during a 3-month recall period in 2006. Road traffic injuries were defined as injuries incurred as a result of a road traffic collision involving at least one vehicle in motion on a public or private road that resulted in at least one person being injured. RESULTS: There were 56 road traffic injuries reported by the surveyed students yielding a rate of 3.6 percent over the 3-month period. The greatest percentage of those injuries involved a motorcycle (80%). Nearly two fifths of injuries resulted in a period of activity restriction lasting one day or more (39%). The multivariable logistic regression analysis indicated that there were statistically significant associations between the assignment of extra homework by parents (odds ratio [OR] = 3.78, 95% confidence intervals [CI] = 1.49-9.60, p-value < 0.01) and parents' treatment for poor academic performance (OR = 2.18, 95% CI = 1.18-4.02, p-value < 0.05) with road traffic injuries and difficulty falling asleep was a marginally a significant risk factor (OR = 2.03, 95% CI = 0.78-5.28, p-value = 0.06). CONCLUSION: School-related stress and sleep disturbance were identified as possible risk factors for road traffic injuries among students in a rural area of China. Further research is warranted in order to develop prevention strategies to address these preventable injuries.

BACKGROUND: Risk-factor research and prevention programs targeting drowning deaths in children have been well developed in industrialized countries, but little research has been undertaken in developing countries where the majority of drowning deaths occur. We conducted an epidemiological study to describe the sociodemographic characteristics, drowning circumstances, and medical service in drowning deaths of children in Xiamen city and suburbs, People's Republic of China. MATERIAL AND METHODS: Drowning deaths in 1-14-year-old children between 2001 and 2005 were identified using death certificates. Parents of each case were interviewed face to face about the sociodemographics of the family and child, the drowning event, and medical care received. Mortalities were calculated using census data for urban and rural areas, and Poisson regression was used to evaluate confounding effects and interactions of several major risk factors for drowning death. RESULTS: Of 67 drowning deaths identified, 52 (77.6%) were males. A higher proportion of deaths were in children aged 5-9 years (40.3%) and 10-14 years (40.3%). The drowning mortality per 100 000 population was 5.84 in rural areas and 0.75 in urban areas. Drowning events occurred most commonly during the summer months (56.7% from June to August), during the hours of 13:00-17:59 (62.7%), and in natural or man-made bodies of water (eg, ponds, ditches, construction sites, and wells). None of the children were proficient swimmers, the majority of drowning events (88.1%) occurred in the absence of adult supervision, and 86.6% children died at the scene without any medical care. Results from muiltivariable Poisson regression analysis indicated that 10-14-year-old boys were at the highest risk of drowning deaths in this area. DISCUSSION AND CONCLUSIONS: Drowning deaths in children in Xiamen city and suburbs follow trends that are markedly different from patterns observed in other countries. Different prevention strategies may be required for preventing child drowning deaths in Xiamen and other developing regions.

Murine T-bet (T-box expressed in T cells) is a master regulator of IFN-gamma gene expression in NK and T cells. T-bet also plays a critical role in autoimmunity, asthma and other diseases. However, cis elements or trans factors responsible for regulating T-bet expression remain largely unknown. Here, we report on our discovery of six Sp1-binding sites within the proximal human T-BET promoter that are highly conserved among mammalian species. Electrophoretic mobility shift assays demonstrate a physical association between Sp1 and the proximal T-BET promoter with a direct dose response between Sp1 expression and T-BET promoter activity. Ectopic overexpression of Sp1 also enhanced T-BET expression and cytokine-induced IFN-gamma secretion in NK cells and T cells. Mithramycin A, which blocks the binding of Sp1 to the T-BET promoter, diminished both T-BET expression and IFN-gamma protein production in monokine-stimulated primary human NK cells. Collectively, our results suggest that Sp1 is a positive transcriptional regulator of T-BET. As T-BET and IFN-gamma are critically important in inflammation, infection, and cancer, targeting Sp1, possibly with mithramycin A, may be useful for preventing and/or treating diseases associated with aberrant T-BET or IFN-gamma expression.

Activated monocytes produce proinflammatory cytokines (monokines) such as interleukin (IL)-12, IL-15, and IL-18 for induction of interferon-gamma (IFN-gamma) by natural killer (NK) cells. NK cells provide the antiinflammatory cytokine transforming growth factor (TGF)-beta, an autocrine/negative regulator of IFN-gamma. The ability of one signaling pathway to prevail over the other is likely important in controlling IFN-gamma for the purposes of infection and autoimmunity, but the molecular mechanism(s) of how this counterregulation occurs is unknown. Here we show that in isolated human NK cells, proinflammatory monokines antagonize antiinflammatory TGF-beta signaling by downregulating the expression of the TGF-beta type II receptor, and its signaling intermediates SMAD2 and SMAD3. In contrast, TGF-beta utilizes SMAD2, SMAD3, and SMAD4 to suppress IFN-gamma and T-BET, a positive regulator of IFN-gamma. Indeed, activated NK cells from Smad3(-/-) mice produce more IFN-gamma in vivo than NK cells from wild-type mice. Collectively, our data suggest that pro- and antiinflammatory cytokine signaling reciprocally antagonize each other in an effort to prevail in the regulation of NK cell IFN-gamma production.
