ABSTRACT

Despite knowledge on the causes and prevention strategies for travelers' diarrhea (TD), it continues to be one of the most common illnesses experienced by U.S. international travelers. However, studies of risk factors associated with TD among U.S. travelers are limited. In this study, we aimed to determine the incidence rate of TD, the proportion of travelers who experience TD, and to identify risk factors associated with TD. In this cross-sectional study, we collected and analyzed data from anonymous posttravel questionnaires submitted by international travelers recruited during their pretravel visit at two travel clinics in Salt Lake City, Utah, from October 2016 to March 2020. Of 571 travelers who completed posttravel surveys, 484 (85%) answered the TD question, of which 111 (23%) reported TD, for an incidence rate of 1.1 episodes per 100 travel-days (95% confidence interval [CI]: 0.9-1.4). In a multivariable model, visiting Southeast Asian (odds ratio [OR]: 2.60; 95% CI: 1.45-4.72) and African (OR: 2.06; 95% CI: 1.09-3.93]) WHO regions, having 10 or more individuals in the group (OR: 3.91; 95% CI: 1.50-11.32]), longer trip duration (OR: 1.01; 95% CI: 1.00-1.02), visiting both urban and rural destinations (OR: 1.94; 95% CI: 1.01-3.90), and taking medications/supplements to prevent TD (OR: 2.74; 95% CI: 1.69-4.47) were statistically significantly associated with increased odds of reporting TD. TD continues to be common in international travelers from the United States. Our findings provide insights regarding travelers' behaviors regarding TD in international travelers from high-income countries and shows the need for additional research into prevention strategies for travelers' diarrhea.

ABSTRACT

BACKGROUND: Skilled attendance at birth is considered key to accomplishing Sustainable Development Goal (SDG) 3.1 aimed at reducing maternal mortality. Many maternal deaths can be prevented if a woman receives care by skilled health personnel. Maternal utilization of skilled health delivery services in rural areas in low- and middle-income countries is 70% compared to 90% in urban areas. Previous studies have found community-based interventions may increase rural maternal uptake of skilled health delivery services, but evidence is lacking on which strategies are most effective. OBJECTIVE: To review the effectiveness of community-based strategies to increase rural maternal utilization of skilled health personnel for childbirth delivery in low-and middle-income countries. METHODS: We conducted a narrative review. PubMed, CINAHL, Cochrane Library, and PsycINFO databases were searched for articles from database inception through 13 November 2019. Key search terms were pre-determined. Information was extracted on studies meeting our inclusion criteria: cluster and randomized trials, rural setting, reproductive aged women, community engagement, low- and middle-income countries. Studies were considered effective if statistically significant (p < 0.05). A narrative synthesis was conducted. RESULTS: Ten cluster randomized trials out of 5,895 candidate citations met the inclusion criteria. Strategies included home-based visits, women's groups, and combined approaches. Out of the ten articles, only three studies were found to significantly increase maternal uptake of skilled health personnel for delivery, and each used a different strategy. The results are inconclusive as to which strategies are most effective. Limitations of this review include heterogeneity and generalizability of studies. CONCLUSIONS: This research suggests that different strategies may be effective at improving maternal utilization of skilled health personnel for delivery in certain rural settings while ineffective in others. More research is warranted to better understand the context in which strategies may be effective and under what conditions.

ABSTRACT

BACKGROUND: Acute gastrointestinal (GI) illnesses are of the most common problems evaluated by physicians and some of the most preventable. There is evidence of GI pathogen transmission when people are in close contact. The COVID-19 pandemic led to the sudden implementation of widespread social distancing measures in the United States. There is strong evidence that social distancing measures impact the spread of SARS-CoV-2, and a growing body of research indicates that these measures also decrease the transmission of other respiratory pathogens. OBJECTIVE: This study aims to investigate the impact of COVID-19 social distancing mandates on the GI pathogen positivity rates. METHODS: Deidentified GI Panel polymerase chain reaction test results from a routinely collected diagnostic database from January 1, 2019, through August 31, 2020, were analyzed for the GI pathogen positivity percentage. An interrupted time series analysis was performed, using social distancing mandate issue dates as the intervention date. The following 3 target organisms were chosen for the final analysis to represent different primary transmission routes: adenovirus F40 and 41, norovirus GI and GII, and Escherichia coli O157. RESULTS: In total, 84,223 test results from 9 states were included in the final data set. With the exception of E coli O157 in Kansas, Michigan, and Nebraska, we observed an immediate decrease in positivity percentage during the week of social distancing mandates for all other targets and states. Norovirus GI and GII showed the most notable drop in positivity, whereas E coli O157 appeared to be least impacted by social distancing mandates. Although we acknowledge the analysis has a multiple testing problem, the majority of our significant results showed significance even below the .01 level. CONCLUSIONS: This study aimed to investigate the impact of social distancing mandates for COVID-19 on GI pathogen positivity, and we discovered that social distancing measures in fact decreased GI pathogen positivity initially. The use of similar measures may prove useful in GI pathogen outbreaks. The use of a unique diagnostic database in this study exhibits the potential for its use as a public health surveillance tool.

ABSTRACT

With an increasing number of adolescents participating in international travel, little is known about travel-related behaviors and health risks in this age group. In the years 2015-2016, we conducted an anonymous, posttravel, questionnaire-based survey with the aim to compare self-reported practices and travel-related symptoms between adolescents (< 18 years old, N = 87) and adults (≥ 18 years old, N = 149) who came to our travel clinic before their humanitarian missions. They had the same pretravel health education, and traveled together to perform similar activities. In univariate analysis, compared with adults, we found that adolescents reported less prior international travel (P < 0.001), more often wore long-sleeved clothing for malaria prevention (P < 0.001) but less often for sun protection (P = 0.009), more often used insect repellents (P = 0.011), and less often had diarrhea (P = 0.024). All other practices and health outcomes were similar between the groups. Multivariate analyses using Bayesian network show strong associations between adults and prior travel experience, and not wearing long-sleeve clothing for malaria prevention. We also found strong associations between prior international travel and sustaining an injury, and having jet lag, as well as between taking malaria prophylaxis and not having diarrhea. Overall, most practices and health outcomes were similar between age groups. Adolescent age and lack of prior international travel experience did not have significant impacts on practices and health outcomes. Our findings highlight the need for more effective strategies to improve the behaviors and health outcomes in both adolescents and adults.

ABSTRACT

BACKGROUND: Anaemia is a significant cause of mortality in children in sub-Saharan Africa where blood transfusion is often available only at referral hospitals. Understanding the pattern of referrals by health facilities is essential to identify the delays that affect child survival. AIM: To determine if there was a correlation between change in haemoglobin (Hb) level and distance from referring facilities to Kamuzu Central Hospital (KCH) in Malawi, and whether distance affected mortality rates. METHODS: This was a retrospective cohort study of 2259 children referred to KCH whose Hb was measured at the referring facility or at KCH. Maps were created using ArcGIS® software. The relationship between distance from KCH and change in Hb was assessed by χ2 analysis and multiple linear regression with SAS© software. RESULTS: The majority of children were referred by health facilities in the Lilongwe District. When categorised as Hb <4, 4-6 or >6 g/dL, 87.0% of children remained in the same category during transfer. There was no significant relationship between Hb drop and distance from KCH. Distance from KCH was not a significant predictor of Hb level at KCH or Hb change. However, mortality rates were significantly higher in facilities that were 10-50 km from KCH than in those which were <10 km away. CONCLUSIONS: Using distance as a proxy for time, this suggests that referring facilities are transferring children sufficiently quickly to avert significant reductions in Hb. Despite this, there is a need to identify the factors that influence the decision to transfer anaemic children.

ABSTRACT

Differences in jurisdictional public health actions have played a significant role in the relative success of local communities in combating and containing the COVID-19 pandemic. We forecast the possible COVID-19 outbreak in one US state (Utah) by applying empirical data from South Korea and Italy, two countries that implemented disparate public health actions. Forecasts were created by aligning the start of the pandemic in Utah with that in South Korea and Italy, getting a short-run forecast based on actual daily rates of spread, and long-run forecast by employing a log-logistic model with four parameters. Applying the South Korea model, the epidemic peak in Utah is 169 cases/day, with epidemic resolution by the end of May. Applying the Italy model, new cases are forecast to exceed 200/day by mid-April, with the potential for 250 new cases a day at the epidemic peak, with the epidemic continuing through the end of August. We identify a 3-month variation in the likely length of the pandemic, a 1.5-fold difference in the number of daily infections at outbreak peak, and a 3-fold difference in the expected cumulative cases when applying the experience of two developed countries in handling this virus to the Utah context.

ABSTRACT

In 2017, there were over 65 million displaced persons at the global level, with approximately 23 million of these people living as refugees around the world. In this same year, the US resettled 53,716 refugees, with the State of Utah receiving 954 of those refugees. Refugees, in general, often face health-related challenges upon resettlement. Since the health of aging refugee men and women is of growing concern, host communities face significant challenges in accommodating the health needs of a diverse refugee population. This study, a review of physical and mental health data from the Utah Department of Health, was undertaken in an effort to ascertain the prevalence of health conditions among refugee men and women 60 years and older arriving in Utah. Findings include information on diseases correlated with increasing age, such as hypertension, decreases in vision, arthritis, and low back pain, which are common among this population of refugees aged 60 years and older. Overall, most of the health conditions assessed affect women and men with a similar prevalence. Some notable exceptions are a history of torture and violence, and a propensity for tobacco use. When dealing with refugee men older than 60 years, providers should consider the psychological ramifications of having endured such atrocities, as well as introduction to evidence-based tobacco cessation programs. When working with refugee women of the same age, an increase in the prevalence of musculoskeletal pain and urinary tract infections should be considered.

ABSTRACT

Introduction Disasters will continue to occur throughout the world and it is the responsibility of the government, health care systems, and communities to adequately prepare for potential catastrophic scenarios. Unfortunately, low-and-middle-income countries (LMICs) are especially vulnerable following a disaster. By understanding disaster preparedness and risk perception, interventions can be developed to improve community preparedness and avoid unnecessary mortality and morbidity following a natural disaster. Problem The purpose of this study was to assess disaster preparedness and risk perception in communities surrounding Trujillo, Peru. METHODS: After designing a novel disaster preparedness and risk perception survey based on guidelines from the International Federation of Red Cross and Red Crescent Societies (IFRC; Geneva, Switzerland), investigators performed a cross-sectional survey of potentially vulnerable communities surrounding Trujillo, Peru. Data were entered and analyzed utilizing the Research Electronic Data Capture (REDCap; Harvard Catalyst; Boston, Massachusetts USA) database. RESULTS: A total of 230 study participants were surveyed, composed of 37% males, 63% females, with ages ranging from 18-85 years old. Those surveyed who had previously experienced a disaster (41%) had a higher perception of future disaster occurrence and potential disaster impact on their community. Overall, the study participants consistently perceived that earthquakes and infection had the highest potential impact of all disasters. Twenty-six percent of participants had an emergency supply of food, 24% had an emergency water plan, 24% had a first aid kit at home, and only 20% of the study participants had an established family evacuation plan. CONCLUSION: Natural and man-made disasters will remain a threat to the safety and health of communities in all parts of the world, especially within vulnerable communities in LMICs; however, little research has been done to identify disaster perception, vulnerability, and preparedness in LMIC communities. The current study established that selected communities near Trujillo, Peru recognize a high disaster impact from earthquakes and infection, but are not adequately prepared for potential future disasters. By identifying high-risk demographics, targeted public health interventions are needed to prepare vulnerable communities in the following areas: emergency food supplies, emergency water plan, medical supplies at home, and establishing evacuation plans.

ABSTRACT

In this study, a fluorogenic heterotrophic plate count test for drinking water was modified in order to detect the presence of carbapenem-resistant bacteria. Antimicrobial agents and concentrations were selected based on recoveries of known carbapenem-resistant and carbapenem-susceptible strains inoculated into simulated samples. The modified method was field-tested on 19 drinking water samples from the New Delhi, India distribution system. Samples exhibiting fluorescence indicated bacterial growth in the presence of the supplemented antimicrobial agents, and organisms from these samples were cultured. Twenty-one Gram-negative isolates were identified from nine of the 19 samples and the meropenem minimum inhibitory concentrations were determined. Ultimately, eight carbapenem-resistant organisms were isolated from five sampling sites within the New Delhi water distribution system.
