RESUMO

BACKGROUND: Tuberculosis (TB) is a preventable and curable disease, but mortality remains high among those who develop sepsis and critical illness from TB. METHODS: This was a population-based, multicentre retrospective cohort study of patients admitted to all 15 publicly funded Hong Kong adult intensive care units (ICUs) between 1 April 2008 and 31 March 2019. 940 adult critically ill patients with at least one positive Mycobacterium tuberculosis (MTB) culture were identified out of 133 858 ICU admissions. Generalised linear modelling was used to determine the impact of delay in TB treatment on hospital mortality. Trend of annual Acute Physiology and Chronic Health Evaluation (APACHE) IV-adjusted standardised mortality ratio (SMR) over the 11-year period was analysed by Mann-Kendall's trend test. RESULTS: ICU and hospital mortality were 24.7% (232/940) and 41.1% (386/940), respectively. Of those who died in the ICU, 22.8% (53/232) never received antituberculosis drugs. SMR for ICU patients with TB remained unchanged over the study period (Kendall's τb=0.37, p=0.876). After adjustment for age, Charlson comorbidity index, APACHE IV, albumin, vasopressors, mechanical ventilation and renal replacement therapy, delayed TB treatment was directly associated with hospital mortality. In 302/940 (32.1%) of patients, TB could only be established from MTB cultures alone as Ziehl-Neelsen staining or PCR was either not performed or negative. Among this group, only 31.1% (94/302) had concurrent MTB PCR performed. CONCLUSIONS: Survival of ICU patients with TB has not improved over the last decade and mortality remains high. Delay in TB treatment was associated with higher hospital mortality. Use of MTB PCR may improve diagnostic yield and facilitate early treatment.

RESUMO

The annual number of opioid prescriptions for pain relief has been increasing in the United States. This increase has raised concerns about prescription opioid abuse and overdose. The purpose of this study was to examine opioid risks (risk factors that increase the chance of opioid abuse) among uninsured primary care patients utilizing a free clinic. Data were collected using a self-administered paper survey in the waiting room of the free clinic from May to July 2017 (N = 506). Higher levels of somatic symptoms were associated with higher levels of opioid risks. U.S.-born English speakers had higher levels of opioid risk than non-U.S.-born English speakers and Spanish speakers. Being employed was associated with higher levels of opioid risk while attending college or being postcollegiate was related to lower levels of opioid risk. Research surrounding best practices, prescription trends, and population risk is vital in driving health and social policy. Further research would benefit from examining where people are obtaining opioids. In addition, further research on opioid abuse among Hispanic populations would be beneficial. Finally, future studies should examine how prescribing practices are different among free clinic health professionals in comparison to health care professionals working in-patient or at for-profit clinics.

RESUMO

A novel salicylideneaniline-based fluorescent sensor, SB1, with a unique excited-state intramolecular charge transfer-excited-state intramolecular proton transfer (ESICT-ESIPT) coupled system was synthesized and demonstrated to fluorescently sense CN(-) with specific selectivity and high sensitivity in aqueous media based on ESICT-ESIPT switching. A large blue shift (96 nm) was also observed in the absorption spectra in response to CN(-). The bleaching of the color could be clearly observed by the naked eye. Moreover, SB1-based test strips were easily fabricated and low-cost, and could be used in practical and efficient CN(-) test kits. Density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations further support the cyanide-induced ESICT-ESIPT switching mechanism. The results provide the proof of concept that the colorimetric and ratiometric fluorescent cyanide-selective chemodosimeter can be created based on an ESICT-ESIPT coupled system.

RESUMO

BACKGROUND: Immigration stress includes acculturation stress and the stress related to language barriers, discrimination, occupational challenges, and feelings of isolation from society and a sense of newness or loss. AIMS: The purpose of this study was to examine immigration stress among refugees resettled in the United States. METHODS: A self-administered or interviewer-administered survey was collected from individuals with a refugee background in Utah from summer through fall in 2017 (N = 190). RESULTS: Older age was associated with higher levels of financial stress and homesickness. Poorer levels of self-rated health and fewer somatic symptoms were related to higher levels of homesickness and language barriers. Higher educational attainment was associated with higher levels of financial stress. CONCLUSION: Refugees are a vulnerable population due to being displaced to a foreign country and having to quickly learn a new language and different culture. It is imperative to gain more knowledge on diverse refugee groups and ways in which they can maintain optimum quality of life through and after the resettlement process.

RESUMO

PURPOSE: The purpose of this study is to examine the following questions: 1) Do refugees and non-refugees differ in self-rated health? 2) Do refugees and non-refugees differ in cancer risk awareness? and 3) Are lifestyle factors such as diet, physical activity participation, and weight status risk or protective factors of cancer risk awareness? METHODS: A self-administered or interviewer-administered survey were collected from adults with a refugee background from spring to fall in 2017 in Salt Lake County, Utah. Free clinic data (a non-refugee comparison group) were collected using a self-administered survey from May to June in 2017 from a free clinic in Salt Lake County, Utah. RESULTS: Refugees reported better self-rated health and were less likely to be obese/overweight, have family history of cancer, and have healthy diet. Refugees reported lower levels of cancer risk awareness than free clinic non-refugee patients. Having a healthy diet was associated with higher levels of cancer risk awareness. CONCLUSION: Future studies should examine cultural differences related to cancer risk awareness among refugee populations.

RESUMO

OBJECTIVES: Determine 90-day mortality of mechanically ventilated ward patients outside the intensive care unit (ICU) and its association with organisational factors. DESIGN: Multicentre prospective observational study of mechanically ventilated ward patients. Modified Poisson regression was used to assess association between nurse to patient ratio (NPR) and 90-day mortality, adjusted for designated medical team, Society of Critical Care Medicine (SCCM) triage priority and centre effect. NPR was divided into low (1:9.6 to 1:10), medium (1:6 to 1:8) and high (1:2.6). Sensitivity analysis was conducted for pneumonia with or without acute respiratory distress syndrome (ARDS) to assess magnitude of association. SETTING: 7 acute public hospitals in Hong Kong. PARTICIPANTS: All 485 mechanically ventilated patients in wards from participating hospitals between 18 January 2016 and 17 April 2016 were recruited. Three hundred patients were included after excluding patients with limitation of therapy within 24 hours of intubation. MAIN OUTCOMES: 90-day mortality, Mortality Prediction Model III Standardised mortality ratio (MPMIII0 SMR). RESULTS: 201 patients died within 90 days after intubation (67.0%, 95% CI 61.5% to 72.1%), with MPMIII0 SMR 1.88, 95% CI 1.63 to 2.17. Compared with high NPR, medium and low NPRs were associated with higher risk of 90-day mortality (adjusted relative risk (RRadj) 1.84, 95% CI 1.70 to 1.99 and 1.64, 95% CI 1.47 to 1.83, respectively). For 114 patients with pneumonia with or without ARDS, low to medium NPR, too sick to benefit from ICU (SCCM priority 4b), no ICU consultation and designated medical team were associated with risk of 90-day mortality (RRadj 1.49, 95% CI 1.40 to 1.58; RRadj 1.60, 95% CI 1.49 to 1.72; RRadj 1.34, 95% CI 1.27 to 1.40; RRadj 0.85, 95% CI 0.78 to 0.93, respectively). CONCLUSION: The 90-day mortality rates of mechanically ventilated ward patients were high. NPR was an independent predictor of survival for mechanically ventilated ward patients.

RESUMO

The global burden of mental health disorders is a significant public health issue. One population that has a risk for mental health issues is college students. Little is known about perceptions of mental illness and mental health services among college students in Vietnam. The purpose of this study is to describe perceptions of mental illness and mental health services among college students in Vietnam, and to compare them with those in the United States (US). The cross-sectional data were collected using a self-administered survey from January to March in 2018 at a national university in Vietnam, and a state university in the US. The study revealed differences in perceptions of causes of mental health between Vietnamese and US participants. Vietnamese participants tended to believe that individuals with mental illness were dangerous and need to be kept out from the community, while US participants perceived that mental illnesses are the same as other illnesses. An important indicator of Vietnamese perceptions of mental health was the low likelihood of seeking formal help because of preference for seeking help from family or friends for mental illness. Interventions, such as mental health awareness campaigns or training courses should be provided for college students in Vietnam. Some strategies to improve mental health among college students used in the US may help to reduce stigma toward mental illness in Vietnam.

RESUMO

The purpose of this study was to examine the health and well-being of women migrating from predominantly Muslim countries to the U.S. Women from predominantly Muslim countries completed a paper survey on the following topics from June to December in 2016 (N=102): depression; physical functioning; self-reported general health; experiences with health care; and demographic characteristics. There were several women's health-related issues: low rates for mammography and Pap smear screening, and preference for female physicians and/or physicians from the same culture. Only one-third of the participants had received a physical exam in the past year, and having done so was related to higher levels of depression and worse physical functioning. The participants who were not in a refugee camp reported higher levels of depression than those who were.

RESUMO

OBJECTIVES: Refugees resettled in the US may be at risk for cardiovascular disease (CVD). However, little is known about CVD-related issues among Karen refugees who have migrated to the US from the Thai-Myanmar border. The purpose of this study was to examine CVD-related health beliefs and lifestyle issues among Karen refugees resettled in the US. METHODS: Karen refugees resettled in the US from the Thai-Myanmar border (n=195) participated in a survey study on health beliefs related to CVD, salt intake, physical activity (PA), and smoking in the fall of 2016. RESULTS: A high-salt diet, physical inactivity, and smoking were major lifestyle problems. Participants who adhered to a low-salt diet considered themselves to be susceptible to CVD. Most participants did not engage in regular PA. Regular PA was associated with less perceived susceptibility to CVD and greater perceived benefits of a healthy lifestyle for decreasing the likelihood of CVD. CONCLUSIONS: Each refugee population may require individualized strategies to promote PA and a healthy diet. Future studies should develop health education programs that are specifically designed for Karen refugees and evaluate such programs. In addition to health education programs on healthy lifestyle choices, tobacco cessation programs seem to be necessary for Karen refugees. At the same time, it is important to foster strategies to increase the utilization of preventive care among this population by promoting free or reduced-fee resources in the community to further promote their health.
