RESUMO

OBJECTIVE: To describe the characteristics of postpartum people who did and did not enroll in a breastfeeding peer-counselor mobile health (mHealth) texting program as well as the issues raised through 2-way texting with peer counselors. DESIGN: Pilot intervention study involving two Special Supplemental Nutrition Programs for Women Infants and Children (WIC) sites in the District of Columbia over 1 year. SAMPLE: WIC recipients. MEASUREMENTS: Descriptive statistics, comparison of recipients who enrolled or not and qualitative content analysis of text messages. INTERVENTION: A breastfeeding peer counselor texting program entitled BfedDC involving routine 1-way programmed messages and 2-way texting capacity for recipients to engage with peer counselors. RESULTS: Among our sample (n = 1642), nearly 90% initiated breastfeeding. A total of 18.5% (n = 304) enrolled in the BfedDC texting program, of whom 19.7% (n = 60) utilized the 2-way texting feature. Message content covered seven content themes and included inquiries about expressing human milk, breastfeeding difficulties, breastfeeding frequency and duration, appointments and more. CONCLUSIONS: Although enrollment was relatively low in BfedDC, benefits included 1-way supportive texts for breastfeeding and the ability to 2-way text with peer counselors. This program aligns with the Surgeon General's Call to Action to Support Breastfeeding and promotes breastfeeding equity in low-income people.

RESUMO

BACKGROUND: Amidst the COVID-19 pandemic, there has been growing concern about the declining mental health and healthy behaviors compared to pre-pandemic levels. Despite this, there is a lack of longitudinal studies that have examined the relationship between health behaviors and mental health during the pandemic. In response, the statewide COVIDsmart longitudinal study was launched. The study's main objective is to better understand the effects of the pandemic on mental health. Findings may provide a foundation for the identification of public health strategies to mitigate future negative impacts of the pandemic. METHODS: Following online recruitment in spring of 2021, adults, ages 18 to 87, filled out social, mental, economic, occupational, and physical health questionnaires on the digital COVIDsmart platform at baseline and through six monthly follow-ups. Changes in the participant's four health behaviors (e.g., tobacco and alcohol consumption, physical activity, and social media use), along with sex, age, loneliness score, and reported social and economic (SE) hardships, were analyzed for within-between group associations with depression and anxiety scores using Mixed Models Repeated Measures. RESULTS: In this study, of the 669 individuals who reported, the within-between group analysis indicated that younger adults (F = 23.81, p < 0.0001), loneliness (F = 234.60, p < 0.0001), SE hardships (F = 31.25, p < 0.0001), increased tobacco use (F = 3.05, p = 0.036), decreased physical activity (F = 6.88, p = 0.0002), and both positive and negative changes in social media use (F = 7.22, p = 0.0001) were significantly associated with worse depression scores. Additionally, females (F = 6.01, p = 0.015), younger adults (F = 32.30, p < 0.0001), loneliness (F = 154.59, p < 0.0001), SE hardships (F = 22.13, p < 0.0001), increased tobacco use (F = 4.87, p = 0.004), and both positive and negative changes in social media use (F = 3.51, p = 0.016) were significantly associated with worse anxiety scores. However, no significant changes were observed in the within-between group measurements of depression and anxiety scores over time (p > 0.05). Physical activity was not associated with anxiety nor was alcohol consumption with both depression and anxiety (p > 0.05). CONCLUSIONS: This study demonstrates the longitudinal changes in behaviors within the context of the COVID-19 pandemic. These findings may facilitate the design of preventative population-based health approaches during the COVID-19 pandemic or future pandemics.

RESUMO

Objectives. To estimate differences in breastfeeding initiation (BFI) rates between African Americans and Black immigrants enrolled in the District of Columbia Special Supplemental Nutrition Program for Women, Infants and Children (WIC) between 2007 and 2019. Methods. We used data collected as part of routine WIC program activities for first-time mothers (n = 38 142). Using multivariable logistic regression models, we identified determinants of BFI for African Americans, Black immigrants, non-Hispanic Whites, and Hispanics. To assess the trend in BFI over time, we calculated the average of the annual percentage changes. Results. Compared with African Americans, Black immigrants had a 2.7-fold higher prevalence and Hispanics had a 5.8-fold higher prevalence of BFI. The average of the annual percentage changes was 0.85 for Hispanics, 3.44 for Black immigrants, 4.40 for Non-Hispanic Whites, and 4.40 for African Americans. African Americans had the only statistically significant change (P < .05). Disparities in BFI persisted over the study period, with African Americans demonstrating the lowest rates each year. Conclusions. Significant differences exist in BFI between Black immigrants and African Americans. Combining African Americans and Black immigrants masks important differences, overestimates rates among African Americans, and may lead to missed opportunities for targeting interventions and policies to improve breastfeeding.

RESUMO

BACKGROUND: During March of 2020 the Centers for Disease Control and Prevention (CDC) announced non-pharmaceutical intervention (NPI) guidance as the primary mitigation strategy against growing COVID-19 community spread due to the absence of a vaccine or effective treatment at that time. CDC guidance states that NPIs are most effective when instituted in an early, targeted, and layered fashion. NPIs are effective in slowing spread, and measures should be custom-tailored to each population. This study examines factors associated with implementation and timing of NPI interventions across large public and private U.S. universities at the onset of the COVID-19 pandemic. METHODS: NPI decisions of interest include when U.S. universities canceled international travel, shifted to online learning, moved faculty/staff to remote work, limited campus housing, and closed campus for all non-essential personnel. Cox proportional hazard analyses of retrospective data were conducted to assess the time to NPI events. Hazard ratios were calculated for university governance, campus setting, religious affiliation, health infrastructure, faculty diversity, and student demographics. The methods control for variance inflation factors, COVID case prevalence, and time varying covariates of spring break and states' state of emergency (SOE) orders. This study captures NPI decisions at 575 U.S. universities during spring of 2020 which affected the movement of seven million students and two million employees. RESULTS: Universities located in districts represented by Democratic party congressional members reported earlier NPI implementation than Republican (Cox proportional hazard ratio (HR) range 0.61-0.80). University religious affiliation was not associated with the timing any of the NPI decisions. Universities with more diverse faculty showed an association with earlier NPI implementation (HR range 0.65-0.76). The existence of university-affiliated health infrastructure was not associated with NPI timing. CONCLUSION: University NPI implementation was largely driven by local COVID-19 epidemiology, culture and political concerns. The timing of university NPI decisions varied by regional politics, faculty demographics, university governance, campus setting, and foreign student prevalence adjusting for COVID-19 state case prevalence and spring break timing. Religious affiliation and presence of university health infrastructure were not associated with timing.

RESUMO

BACKGROUND AND AIM: Helicobacter pylori inhabits the gastric mucosa of humans and causes 89% of all gastric cancers. This is the first study of the seroprevalence, spatial distribution, and risk factors for H pylori in Jordan. MATERIALS AND METHODS: This is a cross-sectional study of 460 healthy participants (aged between 15 and 81 years) proportionately sampled across each region of Jordan. Sera samples were tested for H pylori using Enzygnost® anti-H pylori immunoglobulin G enzyme-linked immunosorbent assay. Participants completed a validated questionnaire about potential risk factors including food consumption habits and environmental and animal exposure. Multivariate generalized linear models identified risk factors for infection. RESULTS: The results showed a high seroprevalence (88.6%; 95% confidence interval [CI]: 85.3-91.2) of H pylori in the study population. After adjusting for possible confounders, age, consumption of raw milk, and location of residence were significantly associated with seropositivity. Older participants aged 30-49 years had an 11% greater risk of seropositivity compared to participants aged 15-29 years. Participants who consume raw milk and dairy products have a 9% decreased risk in seropositivity (prevalence ratio = 0.92; 95% CI: 0.84-0.99) compared to those who do not consume these products. CONCLUSION: This study reports a negative association between consumption of raw milk and seropositivity, and this is in line with several studies that report consumption of raw milk may be protective against H pylori. However, because of the risk of other serious pathogens associated with the consumption of raw dairy products, this study recommends pasteurization of raw milk. Future studies on the effect of fermented dairy products on H pylori colorization in gastric mucosa are recommended.

RESUMO

Background: The prevalence of obesity and type 2 diabetes continues to increase. These conditions disproportionately affect minorities and are associated with poor nutrition early in life. Current food-consumption patterns can inform pending dietary guidelines for infants and toddlers. Objective: The aim of this study was to describe infant feeding, complementary feeding, and food and beverage consumption patterns of 0- to 23.9-mo-olds in the general population. Methods: The Feeding Infants and Toddlers Study 2016 is a cross-sectional survey of caregivers of children aged <4 y. Dietary data were collected from a national random sample by using a 24-h dietary recall (n = 3235). The percentage of children consuming foods from >400 food groups was calculated. Differences in the percentage consuming between Hispanic, non-Hispanic white, and non-Hispanic black children aged 0-23.9 mo were evaluated with the use of ORs and 95% CIs. Results: Eighty-three percent of 0- to 23.9-mo-olds (n = 2635) were ever breastfed, 34% of 0- to 3.9-mo-olds (n = 305) and 15% of 4- to 5.9-mo-olds (n = 295) were exclusively breastfed, and 24% of 12- to 14.9-mo-olds (n = 412) consumed breast milk on the day of the recall. Complementary foods were more likely to be introduced before 4 mo in formula-fed infants (27%) than in infants who did not consume formula (5%). Half of 4- to 5.9-mo-olds consumed iron-fortified infant cereal, but few consumed iron-rich meats. Among toddlers (12-23.9 mo; n = 1133), >20% consumed no servings of fruit or vegetables on the day of the recall, approximately half consumed 100% fruit juice, and one-quarter to one-third consumed a sugar-sweetened beverage (SSB). Conclusions: Breastfeeding initiation and duration have improved, but exclusivity remains low. Low consumption of iron-rich foods, fruit, and vegetables and lack of variety in vegetable consumption are problems. Efforts to reduce the consumption of SSBs and 100% fruit juice are warranted in early childhood.

RESUMO

This study aimed to determine the major diseases, antimicrobial use, and resistance in commensal Escherichia coli in dairy cattle in Jordan. Forty-three (large, n = 21; small, n = 22) farms were surveyed. A validated questionnaire was administered to the herdsmen to elicit information about disease prevalence, antimicrobial knowledge, and antimicrobial use. In addition, fecal samples were collected from 5 lactating animals on each farm. A total of 520 E. coli isolates were tested for resistance to 12 antimicrobials. From the herdsmen's perspective, the diseases that require use of veterinary services in large and small production systems were mastitis (51.2%), metritis (51.2%), and enteritis (39.5%), and the most commonly used antimicrobials were oxytetracycline and streptomycin. Dairy herdsmen (83.7%) reported that it is easy to purchase antimicrobials without a veterinary prescription and 97.7% of them more frequently changed the antimicrobial drug rather than increasing the dose when presented with nonresponse to treatment. Escherichia coli isolates exhibited high resistance to streptomycin (47.5%), tetracycline (45.4%), and ampicillin (34.2%). Less than 10% of isolates were resistant to chloramphenicol, kanamycin, gentamicin, ciprofloxacin, and ceftriaxone. Overall, 64.6 and 37.1% of the E. coli isolates exhibited resistance to ≥1 antimicrobial and multidrug resistance (resistance to ≥3 antimicrobial classes), respectively. The isolates exhibited 107 antimicrobial resistance profiles. This study indicates that antimicrobials are frequently misused in dairies in Jordan and that resistance among commensal E. coli toward antimicrobials of human and veterinary importance is high. Therefore, educational programs for herdsmen and enacting regulations and guidelines are necessary to promote the judicious use of antimicrobials in dairy animals in Jordan.

RESUMO

The aim of this study was to determine the prevalence and antimicrobial resistance of mecA and mecC methicillin-resistant Staphylococcus aureus (MRSA) in cattle, sheep, and goat dairy farms in Jordan. Milk samples were collected from bulk tanks at 117 dairy farms (44 cattle, 47 sheep, and 26 goat dairy farms) in each region of the country. MRSA were isolated on mecA and mecC chromogenic media and confirmed by PCR. The confirmed isolates were tested for resistance toward 15 antimicrobials by the disc diffusion method. None of the tested bulk milk samples were positive for mecC and 26% (95% CI 20-32%) were positive for mecA MRSA. Specifically, mecA MRSA was detected in 31.8% (95% CI 17.5-46.1) of cattle, 29.8% (95% CI 16.2-43.4) of sheep, and 11.5% (95% CI - 1.6-24.7%) of goat dairy farms. All isolates (n = 86) exhibited resistance to penicillin, oxacillin, cefoxitin; meanwhile, most isolates (70-85%) exhibited resistance toward gentamicin, clindamycin, rifampicin, neomycin, fusidic acid, erythromycin, tetracycline, and ciprofloxacin. All mecA MRSA isolates were resistant to at least one class of antimicrobials. Isolates from all goat milk, 88% of cattle milk, and 87% of sheep milk samples exhibited resistance to three classes of antimicrobials and were considered multidrug resistant (MDR). These data demonstrate widespread MDR MRSA in dairy ruminants in Jordan, and these rates are higher than those reported in other countries. Such high prevalence of MDR MRSA and mecA MRSA could lead to economic losses in the dairy industry in Jordan and poses a possible public health risk.

RESUMO

There are few effective communication interventions to respond to Ebola Virus Disease (EVD) outbreaks, and their development is a continuing challenge. The largest outbreak of EVD was first recognized in 2014 and once again highlighted the need for health education communication campaigns. EVD emergence and transmission are associated with behaviors that increase exposure to infected individuals and infected wildlife. In 2008-2009, an educational video-centered intervention consisting of a film followed by a structured discussion was developed to improve EVD knowledge, attitudes, and behaviors (KABs) for prevention of EVD and care of infected people. The film was produced for a Congolese audience in local languages and features doctors and residents from the region. The objective of the study was to assess the effectiveness of this intervention to change KABs related to EVD. The intervention was conducted over 12 months and reached >60,000 people; 220 individuals were sampled before and immediately after the intervention, and a subsample of 53 who had received the intervention 1 year earlier were interviewed to assess changes in KABs related to EVD. Statistically significant improvements in EVD recognition, transmission, and mitigation of risk after the intervention were observed. This study also demonstrates significant retention of knowledge one year after the intervention. Overall, the intervention was effective in improving KABs among a limited literacy population and knowledge was retained for more than one year. The materials and approaches developed were used in 2014 as part of a social mobilization strategy in response to an Ebola outbreak in the Congo Basin.

RESUMO

Early in the COVID-19 pandemic, the Centers for Disease Control and Prevention identified Prince William County (PWC), Va. as a hotspot with a high disease rate among Latinos. This study uses spatial, survey, and qualitative data to understand attitudes towards vaccine uptake among PWC Latinos. A quantitative analysis (n=266) estimates the association for vaccine acceptance among Latinos. Next, qualitative interviews with Latinos (n=37) examine vaccine attitudes. Finally, a spatial analysis identifies clusters of social vulnerability and low vaccine uptake in PWC and adjacent counties. Our findings show that a substantial proportion of PWC Latinos had low vaccination rates as of December 2022, two years after the vaccine's release. Side effects and safety and approval concerns were cited in both the quantitative and qualitative studies. Persistent vaccine disparities are concerning given the high hospitalization and mortality rates that prevailed among Latinos early in the pandemic.

RESUMO

Introduction: Firearm sales and firearm-related injuries and deaths increased during the pandemic. Little is known about motivations for firearm purchasing in response to the COVID-19 pandemic and the mental health status of first-time purchasers. The purpose of this study was to estimate the association between firearm purchasing in response to the COVID-19 pandemic and anxiety symptoms, depressive symptoms, and stress. Methods: The authors analyzed data from a survey that approximated a nationally representative sample of American adults (N=3,528) who either did not own firearms (n=2,327) or purchased firearms for the first time in response to the pandemic (n=240). Self-reported stress, depressive symptoms, and anxiety symptoms were determined using standardized self-assessment questionnaires (Perceived Stress Scale, Patient Health Questionnaire, and Depression Anxiety Stress Scale, respectively). Using multivariable logistic regression, the association between firearm purchasing and each mental health measure were assessed after controlling for demographics and other determinants. Results: In each model, first-time firearm owners were more likely to be younger, live in urban areas, believe the government does too much for its citizens, stay home, stock up on items, and keep their children at home. First-time owners had significantly higher odds of anxiety and depressive symptoms than non-owners (AOR=1.05; 95% CI=1.04, 1.07 and AOR=1.15; 95% CI=1.04, 1.26, respectively). Conclusions: First-time firearm purchasers report higher depressive and anxiety symptoms than non-owners, suggesting that there may be a risk of suicide and other related firearm violence.

RESUMO

Objective: To assess the impact of the coronavirus disease 2019 (COVID-19) pandemic on breastfeeding initiation (BFI) and duration among women enrolled in the Special Supplemental Nutrition Program for women, infants, and children (WIC) in Washington District of Columbia (DC). Materials and Methods: We used WIC program data from Washington DC to assess the pandemic's impact on BFI and duration among WIC recipients. t-Tests and unadjusted odds ratios compared breastfeeding outcomes before and during the pandemic. Multivariable logistic and linear regression models estimated the pandemic's impact on initiation and duration, respectively, while controlling for social determinants of health and other factors. Results: BFI was similar among women who gave birth before (61.4%) or during the pandemic (60.4%) (p = 0.359). However, the proportion of women who breastfed at 1 month decreased significantly from 56.1% (before pandemic) to 47.6% (during pandemic) (p < 0.0001). This pattern for duration continued at 3 and 6 months: 46.9% to 37.1% (p < 0.0001) at 3 months and 34.8% to 25.7% (p < 0.0001) at 6 months. On average, women who delivered during the pandemic breastfed 33.9 fewer days than those who delivered before (p < 0.0001). Conclusions: BFI among DC WIC recipients was similar for infants born before or during the pandemic, and determinants of initiation remained similar to previous reports (e.g., race/ethnicity, education). However, for women who initiated breastfeeding, average duration was significantly lower for infants born during the pandemic than before. Our findings suggest the importance of leveraging WIC and other breastfeeding supports to promote breastfeeding during pandemics and other emergencies.

RESUMO

Parapoxviruses are a genus of the double-stranded DNA family of poxviruses that infect ruminants, and zoonotic transmission to humans often results from occupational exposures. Parapoxvirus infection in humans begins with an incubation period of 3 to 7 days, followed by the development of one or more erythematous maculopapular lesions that evolve over the course of several weeks into nodules. In 2009, parapoxvirus infection was diagnosed in two deer hunters in the eastern United States after the hunters had field-dressed white-tailed deer. We describe the clinical and pathological features of these infections and the phylogenetic relationship of a unique strain of parapoxvirus to other parapoxviruses. Deer populations continue to increase, leading to the possibility that there will be more deer-associated parapoxvirus infections.

RESUMO

BACKGROUND: Case investigation and contact tracing are core public health activities used to interrupt disease transmission. These activities are traditionally conducted manually. During periods of high COVID-19 incidence, US health departments were unable to scale up case management staff to deliver effective and timely contact-tracing services. In response, digital contact tracing (DCT) apps for mobile phones were introduced to automate these activities. DCT apps detect when other DCT users are close enough to transmit COVID-19 and enable alerts to notify users of potential disease exposure. These apps were deployed quickly during the pandemic without an opportunity to conduct experiments to determine effectiveness. However, it is unclear whether these apps can effectively supplement understaffed manual contact tracers. OBJECTIVE: The aims of this study were to (1) evaluate the effectiveness of COVID-19 DCT apps deployed in the United States during the COVID-19 pandemic and (2) determine if there is sufficient DCT adoption and interest in adoption to meet a minimum population use rate to be effective (56%). To assess uptake, interest and safe use covariates were derived from evaluating DCTs using the American Psychological Association App Evaluation Model (AEM) framework. METHODS: We analyzed data from a nationally representative survey of US adults about their COVID-19-related behaviors and experiences. Survey respondents were divided into three segments: those who adopted a DCT app, those who are interested but did not adopt, and those not interested. Descriptive statistics were used to characterize factors of the three groups. Multivariable logistic regression models were used to analyze the characteristics of segments adopting and interested in DCT apps against AEM framework covariates. RESULTS: An insufficient percentage of the population adopted or was interested in DCTs to achieve our minimum national target effectiveness rate (56%). A total of 17.4% (n=490) of the study population reported adopting a DCT app, 24.7% (n=697) reported interest, and 58.0% (n=1637) were not interested. Younger, high-income, and uninsured individuals were more likely to adopt a DCT app. In contrast, people in fair to poor health were interested in DCT apps but did not adopt them. App adoption was positively associated with visiting friends and family outside the home (odds ratio [OR] 1.63, 95% CI 1.28-2.09), not wearing masks (OR 0.52, 95% CI 0.38-0.71), and adopters thinking they have or had COVID-19 (OR 1.60, 95% CI 1.21-2.12). CONCLUSIONS: Overall, a small percentage of the population adopted DCT apps. These apps may not be effective in protecting adopters' friends and family from their maskless contacts outside the home given low adoption rates. The public health community should account for safe use behavioral factors in future public health contact-tracing app design. The AEM framework was useful in developing a study design to evaluate DCT effectiveness and safety.

RESUMO

Leptospirosis is a zoonotic disease that is primarily transmitted through close contact with contaminated environments or infected animals. Brazil has the highest number of reported cases of leptospirosis in the Americas (approximately 4,000 annual cases). The purpose of this study is to identify the occupational groups with a higher risk of leptospirosis in Brazil from 2010 through 2015 among suspected cases reported to the national surveillance system. Confirmed and unconfirmed cases of leptospirosis with laboratory diagnosis, 20,193 and 59,034 respectively, were classified into 12 occupational groups. Confirmed cases were predominantly male (79.4%), between 25 and 59 years of age (68.3%), white (53.4%), illiterate or with incomplete primary education (51.1%), and participating in agricultural work (19.9%). After controlling for age, sex, race, and area of residency, the multivariate analysis identified that between confirmed and unconfirmed cases of leptospirosis reported to the Brazilian national surveillance system, five occupational groups are at higher risk for leptospirosis: garbage and recycling collectors (odds ratio [OR] = 4.10; 95% CI = 3.36-4.99); agricultural, forestry, and fishery workers (OR = 1.65; 95% CI = 1.49-1.84); prisoners (OR = 1.56; 95% CI = 1.04-2.35); building workers (OR = 1.36; 95% CI = 1.22-1.51); cleaners and mining workers (OR = 1.25; 95% CI = 1.07-1.45). This is the first nationwide study to examine leptospirosis risk by occupational group in Brazil using national surveillance data. Our results suggest that among suspected cases there was an increased risk among occupational groups with low income and low educational levels.

RESUMO

BACKGROUND: The COVID-19 pandemic has affected people's lives beyond severe and long-term physical health symptoms. Social distancing and quarantine have led to adverse mental health outcomes. COVID-19-induced economic setbacks have also likely exacerbated the psychological distress affecting broader aspects of physical and mental well-being. Remote digital health studies can provide information about the pandemic's socioeconomic, mental, and physical impact. COVIDsmart was a collaborative effort to deploy a complex digital health research study to understand the impact of the pandemic on diverse populations. We describe how digital tools were used to capture the effects of the pandemic on the overall well-being of diverse communities across large geographical areas within the state of Virginia. OBJECTIVE: The aim is to describe the digital recruitment strategies and data collection tools applied in the COVIDsmart study and share the preliminary study results. METHODS: COVIDsmart conducted digital recruitment, e-Consent, and survey collection through a Health Insurance Portability and Accountability Act-compliant digital health platform. This is an alternative to the traditional in-person recruitment and onboarding method used for studies. Participants in Virginia were actively recruited over 3 months using widespread digital marketing strategies. Six months of data were collected remotely on participant demographics, COVID-19 clinical parameters, health perceptions, mental and physical health, resilience, vaccination status, education or work functioning, social or family functioning, and economic impact. Data were collected using validated questionnaires or surveys, completed in a cyclical fashion and reviewed by an expert panel. To retain a high level of engagement throughout the study, participants were incentivized to stay enrolled and complete more surveys to further their chances of receiving a monthly gift card and one of multiple grand prizes. RESULTS: Virtual recruitment demonstrated relatively high rates of interest in Virginia (N=3737), and 782 (21.1%) consented to participate in the study. The most successful recruitment technique was the effective use of newsletters or emails (n=326, 41.7%). The primary reason for contributing as a study participant was advancing research (n=625, 79.9%), followed by the need to give back to their community (n=507, 64.8%). Incentives were only reported as a reason among 21% (n=164) of the consented participants. Overall, the primary reason for contributing as a study participant was attributed to altruism at 88.6% (n=693). CONCLUSIONS: The COVID-19 pandemic has accelerated the need for digital transformation in research. COVIDsmart is a statewide prospective cohort to study the impact of COVID-19 on Virginians' social, physical, and mental health. The study design, project management, and collaborative efforts led to the development of effective digital recruitment, enrollment, and data collection strategies to evaluate the pandemic's effects on a large, diverse population. These findings may inform effective recruitment techniques across diverse communities and participants' interest in remote digital health studies.

RESUMO

Mobile health (mHealth) technologies and telecommunication have rapidly been integrated into the health care delivery system, particularly in developing countries. Resources have been allocated to developing mHealth interventions, including those that use mobile technology for behavior change communication (BCC). Although the majority of mobile phone users worldwide live in the developing world, most research evaluating BCC mHealth interventions has taken place in developed countries. The purpose of this study was to conduct a systematic review of the literature to determine how much evidence currently exists for mHealth BCC interventions. In addition to analyzing available research for methodological rigor and strength of evidence, the authors assessed interventions for quality, applying a set of 9 standards recommended by mHealth experts. The authors reviewed 44 articles; 16 (36%) reported evaluation data from BCC mHealth interventions in a developing country. The majority of BCC mHealth interventions were implemented in Africa (n = 10) and Asia (n = 4). HIV/AIDS (n = 10) and family planning/pregnancy (n = 4) were the health topics most frequently addressed by interventions. Studies did not consistently demonstrate significant effects of exposure to BCC mHealth interventions on the intended audience. The majority of publications (n = 12) described interventions that used two-way communication in their message delivery design. Although most publications described interventions that conducted formative research about the intended audience (n = 10), less than half (n = 6) described targeting or tailoring the content. Although mHealth is viewed as a promising tool with the ability to foster behavior change, more evaluations of current interventions need to be conducted to establish stronger evidence.

RESUMO

Sealpox, a zoonotic disease affecting pinnipeds (seals and sea lions), can occur among captive and convalescing animals. We surveyed 1 worker each from 11 marine mammal centers and interviewed 31 other marine mammal workers to ascertain their knowledge of and experience with sealpox virus and to identify factors associated with sealpox virus outbreaks among pinnipeds in marine rehabilitation facilities. Demographic and health data were obtained for 1,423 pinnipeds at the 11 facilities. Among the 23 animals in which sealpox was clinically diagnosed, 4 arrived at the facility ill, 11 became ill <5 weeks after arrival, and 2 became ill ≥5 weeks after arrival; the timing of illness onset was unknown for 6 animals. Most infections occurred in pinnipeds <1 year of age. Nine affected animals were malnourished; 4 had additional illnesses. Sealpox had also occurred among workers at 2 facilities. Sealpox is a noteworthy zoonosis of rehabilitating convalescing pinnipeds; workplace education can help to minimize risks for human infection.

RESUMO

BACKGROUND: Leptospirosis is one of the most widespread zoonosis in the world and Brazil has the highest number of cases in Latin America. Transmission occurs mainly through exposure to water and soil contaminated by the urine of infected animals. The goals of this study are to describe the geographic distribution, demographic characteristics and exposure factors of urban and rural cases of leptospirosis, and identify spatial clusters in urban and rural areas of Brazil. METHODS/RESULTS: A retrospective epidemiological study was carried out using 16 years (2000-2015) of surveillance data from the Brazilian Ministry of Health. Cases were described by age, sex and race, and exposure factors were characterized in urban and rural areas. A spatial autocorrelation analysis was conducted using local Moran's I to identify urban and rural clusters of disease. On average 3,810 leptospirosis cases were reported annually with higher numbers in urban areas. National urban and rural incidence rates were the same (1.9 cases/100,000 population), however, regional differences were observed. Urban incidence rates were higher in the North and Northeast regions, while rural incidence rates were higher in the Southeast and South. The main exposure factor reported in urban and rural areas was exposure to places with signs of rodents, followed by flood in urban areas and agriculture and animal farming in rural areas. Clusters of leptospirosis were identified in densely populated urban areas of the North, Southeast and South regions, while rural clusters were concentrated in of the Southern region with large agriculture and animal farming practices. CONCLUSIONS: This study highlights that leptospirosis is an important public health problem in both urban and rural areas of Brazil. The results provide decision-makers with detailed information about where disease incidence is high and can be used in the development of prevention and control strategies for priority areas and risk groups.
