RESUMEN

BACKGROUND: Honey improves probiotic survival in vitro. However, if this effect translates to humans has not been investigated. OBJECTIVES: We aimed to determine effects of honey plus yogurt containing the probiotic Bifidobacterium animalis subsp. lactis DN-173 010/CNCM I-2494 (B. animalis) on intestinal transit time, probiotic enrichment, digestive health, mood, and cognition in adults. METHODS: Sixty-six healthy adults (34 female; 33.6 ± 9.8 y; 24.6 ± 3.0 kg/m2) in a crossover trial were randomly assigned to 2-wk yogurt conditions in a counterbalanced order with ≥4-wk washout: 1) Honey (HON): yogurt plus honey and 2) Negative Control (NC): heat-treated yogurt plus sugar. Of the participants, n = 62 completed the trial, and n = 37 (17 female; 32.0 ± 8.3 y; 25.0 ± 2.9 kg/m2) elected to enroll in a third condition (a nonrandomized study extension) after ≥4-wk washout with a reference Positive Control (PC): yogurt plus sugar. At baseline and end of each of the 3 conditions, intestinal transit time was measured with dye capsules; probiotic abundance with fecal DNA 16S sequencing; digestive health with symptom/function records, Bristol stool consistency, Gastrointestinal Tolerability, and Gastrointestinal Quality of Life Index; mood with Positive and Negative Affect Schedule-Short Form, Depression Anxiety Stress Scales-42, Patient-Reported Outcomes Measurement Information System questionnaires, and an emotional image task; and cognition with a spatial reconstruction task. Data were analyzed using linear mixed-effects models (LMMs) with significance at P ≤ 0.05. Baseline and end data were included in the LMM, with fixed effects being treatment, time, treatment by time interaction, and baseline covariate, and the random effect being the participant. RESULTS: B. animalis was enriched in HON (d = 3.54; P = 0.0002) compared to controls with linear discriminant analysis effect size. Intestinal transit time, gastrointestinal health, mood, and cognition did not differ between conditions (LMM: Ps > 0.05). CONCLUSIONS: Yogurt + honey enriched B. animalis but did not reduce intestinal transit time or have other functional gastrointestinal, mood, or cognitive effects in adults. This trial was registered at www. CLINICALTRIALS: gov as NCT04187950 and NCT04901390.

RESUMEN

Whooping cough is a disease caused by Bordetella pertussis, whose morbidity has increased, motivating the improvement of current vaccines. Reverse vaccinology is a strategy that helps identify proteins with good characteristics fast and with fewer resources. In this work, we applied reverse vaccinology to study the B. pertussis proteome and pangenome with several in-silico tools. We analyzed the B. pertussis Tohama I proteome with NERVE software and compared 234 proteins with B. parapertussis, B. bronchiseptica, and B. holmessi. VaxiJen was used to calculate an antigenicity value; our threshold was 0.6, selecting 84 proteins. The candidates were depurated and grouped in eight family proteins to select representative candidates, according to bibliographic information and their immunological response predicted with ABCpred, Bcepred, IgPred, and C-ImmSim. Additionally, a pangenome study was conducted with 603 B. pertussis strains and PanRV software, identifying 3421 core proteins that were analyzed to select the best candidates. Finally, we selected 15 proteins from the proteome study and seven proteins from the pangenome analysis as good vaccine candidates.

RESUMEN

Ranaviruses can cause mass mortality events in amphibians, thereby becoming a threat to populations that are already facing dramatic declines. Ranaviruses affect all life stages and persist in multiple amphibian hosts. The detrimental effects of ranavirus infections to amphibian populations have already been observed in the UK and in North America. In Central and South America, the virus has been reported in several countries, but the presence of the genus Ranavirus (Rv) in Colombia is unknown. To help fill this knowledge gap, we surveyed for Rv in 60 species of frogs (including one invasive species) in Colombia. We also tested for co-infection with Batrachochytrium dendrobatidis (Bd) in a subset of individuals. For Rv, we sampled 274 vouchered liver tissue samples collected between 2014 and 2019 from 41 localities covering lowlands to mountaintop páramo habitat across the country. Using quantitative polymerase chain reaction (qPCR) and end-point PCR, we detected Rv in 14 individuals from 8 localities, representing 6 species, including 5 native frogs of the genera Osornophryne, Pristimantis and Leptodactylus, and the invasive American bullfrog Rana catesbeiana. Bd was detected in 7 of 140 individuals, with 1 co-infection of Rv and Bd in an R. catesbeiana specimen collected in 2018. This constitutes the first report of ranavirus in Colombia and should set off alarms about this new emerging threat to amphibian populations in the country. Our findings provide some preliminary clues about how and when Rv may have spread and contribute to understanding how the pathogen is distributed globally.

RESUMEN

BACKGROUND: There is growing evidence to suggest that exposure to a high concentration of nitrogen dioxide (NO2) can lead to a higher incidence of Acute Respiratory Infections (ARIs) in children; however, such an association remains understudied in Sub-Saharan Africa due to the limited availability of exposure data. This study explored this association by using the satellite-detected tropospheric NO2 concentrations measured by Sentinel-5 Precursor and ARI symptoms in children under age five collected in the Demographic and Health Survey (DHS) in Senegal. METHODS: We matched the daily tropospheric NO2 exposure with the individual ARI symptoms according to the DHS survey clusters spatially and temporally and conducted a logistic regression analysis to estimate the association of exposure to NO2 with ARI symptoms in two preceding weeks. RESULTS: We observed a positive association between exposure to continuous levels of NO2 and ARI symptoms after adjusting for confounders (OR 1.27 per 10 mol/m2, 95% CI: 1.06 - 1.52). When the association was further examined by quartile exposure categories, the 4th quartile category was positively associated with symptoms of ARI after adjusting for confounders (OR 1.71, 95% CI: 1.08-2.69). This suggests that exposure to certain high levels of NO2 is associated with the increased risk of children having symptoms of ARI in Senegal. CONCLUSIONS: This study highlights the need for increased research on the effects of ambient NO2 exposure in Africa as well as the need for more robust, ground-based air monitoring in the region. For a country like Senegal, where more than 90% of the population lives in areas that do not meet the national air quality standards, it is urgently required to implement air pollution prevention efforts to protect children from the health hazards of air pollution.

RESUMEN

OBJECTIVES: Vietnam's post-war globalization, economic development, and urbanization have contributed to a nutrition transition from traditional diets to highly-processed diets, and increased prevalence of childhood overweight and obesity. Our study aims to explore the attitudes and behaviors driving this epidemic. METHODS: This qualitative study focused on the perspectives and practices of Vietnamese parents, schoolteachers and doctors. Semi-structured interviews were conducted with a convenience sample of 12 regarding the historical, social, and cultural influences contributing to childhood overweight and obesity. Audio-recorded interviews were translated and transcribed, then analyzed using modified ground theory to identify themes and representative quotes. RESULTS: Five themes were identified: (1) Change in diet between generations, (2) Preference for rounder children, (3) Unhealthy feeding practices, (4) Reduced physical activity, and (5) Increasing awareness of childhood obesity. A conceptual map detailed the shift from war-time to post-war economic environment and psycho-social context for raising children to be large, safe and academically-successful. CONCLUSIONS FOR PRACTICE: We found that globalization, urbanization and economic development-in the context of historical, social and cultural attitudes-may contribute to increasing child obesity in Vietnam. Obesity prevention through public health and educational institutions should involve policies and programs for healthy eating and exercise, tailored to address parental figures' concerns.

RESUMEN

BACKGROUND: Over recent decades, Vietnam has experienced rapid economic growth, a nutrition transition from the traditional diet to highly-processed and calorie-dense foods and beverages, and an increasing prevalence of childhood overweight/obesity (ow/ob). The goal of this study is to describe the patterns of ow/ob in a longitudinal sample of Vietnamese children from ages 1 to 8, and the sociodemographic and behavioral factors associated with ow/ob at age 8. METHODS: This study is a secondary data analysis of a geographically-representative, longitudinal cohort of 1961 Vietnamese children from the Young Lives Cohort Study from 2002 to 2009. Thirty-one communities were selected with oversampling in rural communities, and children age 1 were recruited from each community using simple random sampling. Surveys of families and measurements of children were collected at child ages 1, 5, and 8. Our specified outcome measure was childhood ow/ob at age 8, defined by the World Health Organization's thresholds for body-mass-index (BMI) for age Z-scores. Associations between early and concurrent socio-behavioral factors, childhood nutrition and physical activity variables were analyzed using STATA 15. Bivariate and multivariable analyses were completed utilizing logistic regression models. RESULTS: The prevalence of ow/ob increased from 1.1% in both sexes at age 1 to 7% in females and 13% in males at age 8. Bivariate analyses show greater likelihood of ow/ob at age 8 was significantly associated with early life sociodemographic factors (at age 1), male sex (OR = 2.2, 1.6-3.1), higher wealth (OR = 1.1-1.4), and urban residence (OR = 4.3, 3-6). In adjusted analyses, ow/ob at age 8 was associated with early nutrition practices at age 5, including frequent consumption of powdered milk (OR = 2.8, 1.6-4.6), honey/sugar (OR = 2.7, 1.8-4.1), prepared restaurant/fast foods (OR = 4.6, 2.6-8.2), and packaged sweets (OR = 3.4, 2.3-4.9). In addition, breastfeeding for 6 months or longer was protective against obesity at age 8 (OR = 0.3, 0.1-0.9). CONCLUSIONS: We found that increased consumption of powdered milk, honey/sugar, packaged sweets, and prepared restaurants/fast foods are associated with childhood ow/ob. In contrast, breastfeeding for 6 months or longer was protective against childhood ow/ob. These findings suggest that public health programs and campaigns aimed to prevent childhood ow/ob in Vietnam should target early feeding practices.

RESUMEN

BACKGROUND: The COVID-19 public health emergency (PHE) has significantly changed medical practice in the United States, including an increase in the utilization of telemedicine. Here, we characterize change in neuro-ophthalmic care delivery during the early COVID-19 PHE, including a comparison of care delivered via telemedicine and in office. METHODS: Neuro-ophthalmology outpatient encounters from 3 practices in the United States (4 providers) were studied during the early COVID-19 PHE (March 15, 2020-June 15, 2020) and during the same dates 1 year prior. For unique patient visits, patient demographics, visit types, visit format, and diagnosis were compared between years and between synchronous telehealth and in-office formats for 2020. RESULTS: There were 1,276 encounters for 1,167 patients. There were 30% fewer unique patient visits in 2020 vs 2019 (477 vs 670) and 55% fewer in-office visits (299 vs 670). Compared with 2019, encounters in 2020 were more likely to be established, to occur via telemedicine and to relate to an efferent diagnosis. In 2020, synchronous telehealth visits were more likely to be established compared with in-office encounters. CONCLUSIONS: In the practices studied, a lower volume of neuro-ophthalmic care was delivered during the early COVID-19 public health emergency than in the same period in 2019. The type of care shifted toward established patients with efferent diagnoses and the modality of care shifted toward telemedicine.

RESUMEN

INTRODUCTION: People living with mental health conditions (MH+) are more likely to smoke cigarettes than people without mental health conditions (MH-) and to experience tobacco-related disparities. The Tips From Former Smokers® (Tips®) campaign is a proven population-level strategy for motivating smokers to quit. In 2016, Tips included ads featuring Rebecca, a former smoker with depression. We evaluated self-reported frequency of exposure to the Rebecca and other Tips ads in association with quit intentions and quit attempts among MH+ and MH- smokers. METHODS: Intentions to quit and past 6-month quit attempts lasting at least 24 hours were reported from a two-wave longitudinal online survey conducted before and after the 2016 Tips campaign with a nationally representative sample of US adult cigarette smokers with (MH+, N = 777) and without (MH-, N = 1806) lifetime mental health conditions. RESULTS: In 2016, among MH+ respondents, greater exposure to the Rebecca ads was significantly associated with increased odds of intending to quit in the next 30 days (adjusted odds ratio [AOR] = 1.40, p < .05) and with reporting a quit attempt in the past 6 months (AOR = 1.25, p < .05). Among MH- respondents, greater exposure to the other Tips ads was associated with increased odds of making a quit attempt (AOR = 1.19, p < .05). CONCLUSIONS: Exposure to the Rebecca ads was associated with a greater likelihood of intentions to quit and quit attempts among MH+ smokers; whereas, exposure to the other (non-mental-health-related) Tips ads was associated with a greater likelihood of quit attempts among MH- smokers. IMPLICATIONS: National media campaigns are an important population-level strategy for reaching specific population groups who are experiencing tobacco-related disparities. The findings support the inclusion of ads featuring people living with mental health conditions in national tobacco education media campaigns, such as Tips.

RESUMEN

Our recent analysis of how soda tax debates appear in the news revealed that oral health professionals seldom appear. By elevating their expert voices, oral health practitioners can contribute new and salient arguments for soda taxes to the public discourse and help advance public policy that improves oral health outcomes. We propose media advocacy strategies that oral health professionals can use to increase their visibility in the news to make the case for soda taxes.

RESUMEN

OBJECTIVES: We investigated the relationships among early childhood caries (ECC), mouth pain, and nutritional status in children aged 1 to 6 years in Southern and Central Vietnam. METHODS: A total of 593 parent-child pairs were recruited from 5 kindergartens or preschools in Ho-Chi Minh City and Da Nang. Parents completed surveys about dietary habits, oral health practices, and children's mouth pain experience; children received anthropometric assessment and dental examinations. RESULTS: There was a high prevalence of dental caries (74.4%), mostly untreated, and mouth pain (47.1%). Moderate correlations were found between parents' and children's consumption of soda (ρ = 0.361; P < .001) and salty snacks (ρ = 0.292; P < .001). Severity of ECC was associated with decreased weight- and body mass index-for-age z-scores. Presence of pulp-involved caries was associated with strikingly lower height-for-age (mean difference = 0.66; P = .001), weight-for-age (mean difference = 1.17; P < .001), and body mass index-for-age (mean difference = 1.18; P < .001) z-scores. Mouth pain was associated with lower body mass index-for-age z-scores (mean difference = 0.29; P = .013). CONCLUSIONS: ECC might negatively affect children's nutritional status, which might be mediated by the depth of decay, chronic inflammation, and mouth pain. Family-based and prevention-oriented nutrition and oral health programs are needed and should start during pregnancy and infancy.

RESUMEN

BACKGROUND: Globalization and increased marketing of non-nutritious foods and beverages are driving a nutrition transition in developing countries, adversely affecting the health of vulnerable populations. This is a visual interpretive study of food, snack, and beverage advertisements (ads) in rural and urban El Salvador to discern the strategies and messages used to promote consumption of highly processed, commercialized products. METHODS: Digital photographs of billboard and wall advertisements recorded a convenience sample of 100 advertisements, including 53 from rural areas and 47 from urban areas in El Salvador. Advertisements were coded for location, type of product, visual details, placement and context. Qualitative methods were used to identify common themes used to appeal to consumers. RESULTS: Advertisements depicted "modern" fast foods, processed snacks and sugary beverages. Overall, the most prominent themes were: Cheap Price, Fast, Large Size, and Modern. Other themes used frequently in combination with these were Refreshment, Sports/Nationalism, Sex and Gender Roles, Fun/Happy Feelings, Family, Friendship and Community, and Health. In rural areas, beverage and snack food ads with the themes of cheap price, fast, and large size tended to predominate; in urban areas, ads for fast food restaurants and the theme of modernity tended to be more prominent. CONCLUSIONS: The advertisements represented a pervasive bombardment of the public with both explicit and subliminal messages to increase consumerism and shift dietary patterns to processed foods and beverages that are low in micronutrients and high in carbohydrates, sugar, fat and salt--dietary changes that are increasing rates of child and adult diseases including tooth decay, obesity, cardiovascular disease and cancer. Global food and beverage industries must be held accountable for the adverse public health effects of their products, especially in low-middle income countries where there are fewer resources to prevent and treat the health consequences. In addition, public health and governmental authorities should learn from the advertising strategies to promote social marketing of public health messages, and enact and enforce regulations to limit the advertisement and sale of unhealthy products, particularly for children in and around schools. This will create healthier social norms and environments for the entire population.

RESUMEN

PROBLEM: Medical educators, clinicians, and health policy experts widely acknowledge the need to increase the diversity of our healthcare workforce and build our capacity to care for medically underserved populations and reduce health disparities. INTERVENTION: The Program in Medical Education for the Urban Underserved (PRIME-US) is part of a family of programs across the University of California (UC) medical schools aiming to recruit and train physicians to care for underserved populations, expand the healthcare workforce to serve diverse populations, and promote health equity. PRIME-US selects medical students from diverse backgrounds who are committed to caring for underserved populations and provides a 5-year curriculum including a summer orientation, a longitudinal seminar series with community engagement and leadership-development activities, preclerkship clinical immersion in an underserved setting, a master's degree, and a capstone rotation in the final year of medical school. CONTEXT: This is a mixed-methods evaluation of the first 4 years of the PRIME-US at the UC Berkeley-UC San Francisco Joint Medical Program (JMP). From 2006 to 2010, focus groups were conducted each year with classes of JMP PRIME-US students, for a total of 11 focus groups; major themes were identified using content analysis. In addition, 4 yearly anonymous, online surveys of all JMP students, faculty and staff were conducted and analyzed. OUTCOME: Most PRIME-US students came from socioeconomically disadvantaged backgrounds and ethnic backgrounds underrepresented in medicine, and all were committed to caring for underserved populations. The PRIME-US students experienced many program benefits including peer support, professional role models and mentorship, and curricular enrichment activities that developed their knowledge, skills, and sustained commitment to care for underserved populations. Non-PRIME students, faculty, and staff also benefited from participating in PRIME-sponsored seminars and community-based activities. Challenges noted by PRIME-US students and non-PRIME students, faculty, and staff included the stress of additional workload, perceived inequities in student educational opportunities, and some negative comments from physicians in other specialties regarding primary care careers. LESSONS LEARNED: Over the first 4 years of the program, PRIME-US students and non-PRIME students, faculty, and staff experienced educational benefits consistent with the intended program goals. Long-term evaluation is needed to examine the participants' medical careers and impacts on California's healthcare workforce and patient outcomes. Attention should also be paid to the challenges of implementing new medical education enrichment programs.

RESUMEN

PURPOSE: To compare disparities in outpatient ophthalmic care during early and later periods of the COVID-19 public health emergency. METHODS: This cross-sectional study compared non-peri-operative outpatient ophthalmology visits by unique patients at an adult ophthalmology practice affiliated with a tertiary-care academic medical center in the Western US during three time periods: pre-COVID (3/15/19-4/15/19), early-COVID (3/15/20-4/15/20), and late-COVID (3/15/21-4/15/21). Differences in participant demographics, barriers to care, visit modality (telehealth, in person), and subspeciality of care were studied using unadjusted and adjusted models. RESULTS: There were 3095, 1172 and 3338 unique patient-visits during pre-COVID, early-COVID and late-COVID (overall age 59.5 ± 20.5 years, 57% female, 41.8% White, 25.9% Asian, 16.1% Hispanic). There were disparities in patient age (55.4 ± 21.8 vs. 60.2 ± 19.9 years), race (21.9% vs. 26.9% Asian), ethnicity (18.3% Hispanic vs. 15.2% Hispanic), and insurance (35.9% vs. 45.1% Medicare) as well as changes in modality (14.2% vs. 0% telehealth) and subspecialty (61.6% vs. 70.1% internal exam specialty) in early-COVID vs. pre-COVID (p < .05 for all). In late-COVID, only insurance (42.7% vs. 45.1% Medicare) and modality of care (1.8% vs. 0% telehealth) persisted as differences compared to pre-COVID. CONCLUSIONS: There were disparities in patients receiving outpatient ophthalmology care during early-COVID that returned close to pre-COVID baseline one year later. These results suggest that there has not been a lasting positive or negative disruptive effect of the COVID-19 pandemic on disparities in outpatient ophthalmic care.

RESUMEN

BACKGROUND: Interest is growing in clinic-based programs that screen for and intervene on patients' social risk factors, including housing, food, and transportation. Though several studies suggest these programs can positively impact health, few examine the mechanisms underlying these effects. This study explores pathways through which identifying and intervening on social risks can impact families' health. METHODS: This qualitative study was embedded in a randomized clinical trial that examined the health impacts of participation in a social services navigation program. We conducted semi-structured interviews with 27 English or Spanish-speaking caregivers of pediatric patients who had participated in the navigation program. Interviews were analyzed using thematic analysis. RESULTS: Caregivers described 3 pathways through which the navigation program affected overall child and/or caregiver health: 1) increasing families' knowledge of and access to social services; 2) helping families connect with health care services; and 3) providing emotional support that reduced caregiver isolation and anxiety. Participants suggested that navigation programs can influence health even when they do not directly impact resource access. DISCUSSION: Social care programs may impact health through multiple potential pathways. Program impacts seem to be mediated by the extent to which programs increase knowledge of and access to social and health care services and support positive relationships between families and program personnel.

RESUMEN

Child undernutrition persists in Cambodia despite recent progress. As Cambodia undergoes a shift in dietary consumption that coincides with economic, demographic, and epidemiologic changes, there is risk of ultra-processed foods and sugar-sweetened beverages displacing nutrient-dense foods during the critical period of infant growth in the first 24 months. The aim of this study was to assess the introduction and intake of foods of low nutritional value and sugar-sweetened beverages and their association with undernutrition among children 24 months of age in rural and semi-urban Cambodia. Cross-sectional analyses of a 24-h dietary recall from a sample (n = 377) of 24-month-olds found that the majority of infants had been introduced to packaged salty snacks and sweets by 12 months of age and to sugar-sweetened beverages by 15 months. By 24 months of age, 78% of children had consumed foods of low nutritional value and 57% consumed a sugar-sweetened beverage on the previous day. Multivariate logistic regression analyses demonstrated that infant intake of a flavored sugary drink on the previous day was associated with over two times the odds of both stunting and wasting, and consumption of packaged sweets on the previous day was associated with over two times the odds of wasting, but no association was found with stunting. These findings underscore the need to improve educational and policy interventions to support healthy feeding practices for infants and young children.

RESUMEN

Negative prognostic communication is often delayed in intensive care units, which limits time for families to prepare for end-of-life. This descriptive study, informed by ethnographic methods, was focused on exploring critical care physician communication of negative prognoses to families and identifying timing influences. Prognostic communication of critical care physicians to nurses and family members was observed and physicians and family members were interviewed. Physician perception of prognostic certainty, based on an accumulation of empirical data, and the perceived need for decision-making, drove the timing of prognostic communication, rather than family needs. Although prognoses were initially identified using intuitive knowledge for patients in one of the six identified prognostic categories, utilizing decision-making to drive prognostic communication resulted in delayed prognostic communication to families until end-of-life (EOL) decisions could be justified with empirical data. Providers will better meet the needs of families who desire earlier prognostic information by separating prognostic communication from decision-making and communicating the possibility of a poor prognosis based on intuitive knowledge, while acknowledging the uncertainty inherent in prognostication. This sets the stage for later prognostic discussions focused on EOL decisions, including limiting or withdrawing treatment, which can be timed when empirical data substantiate intuitive prognoses. This allows additional time for families to anticipate and prepare for end-of-life decision-making.

RESUMEN

BACKGROUND: The global nutrition transition is associated with increased consumption of ultra-processed snack foods and sugar-sweetened beverages (UPF/SSB), contributing to the double burden of child obesity and undernutrition. METHODS: This cross-sectional study describes the prevalence of maternal and child UPF/SSB consumption and the factors associated with frequent consumption in a convenience sample of 749 children ages 6 months through 6 years and their mothers participating in a community-based child oral health program in five informal settlement communities in Mumbai, India. Mothers were interviewed regarding maternal and child oral health and nutrition characteristics, including consumption of beverages and foods associated with tooth decay-milk, soda, tea with sugar, sweets, and chips/biscuits-using standardized questionnaires. Spearman correlations were used to assess for associations between various social factors and the frequency of maternal and child consumption of the five food categories. Chi-square tests were used to assess differences in child consumption patterns by age groups. RESULTS: Though reported soda consumption was low among both mothers and children, nearly 60% of children consumed sweets and chips/biscuits daily, four to five times the rate of mothers. Factors associated with children's frequent consumption of UPF/SSB included lower maternal education level, frequent maternal consumption of UPF/SSB, greater number of household members, greater amount of money given to the child, and closer proximity to a store. CONCLUSION: Our findings demonstrate social factors that may promote UPF/SSB consumption. The nutritional dangers of sugary drinks and non-nutritious snacks for mothers and young children should be addressed across maternal-child health, education, and social service programs. Early childhood nutrition interventions should involve the entire family and community and emphasize the need to limit children's consumption of unhealthy foods and beverages from an early age.

RESUMEN

Childhood caries experience is influenced by family characteristics and oral health practices in the context of many social-commercial determinants. The aim of this study was to explore the relationship between families' number of children, oral health practices and child caries experience in a convenience sample of 1374 children aged 6 months through 6 years and their families from Ecuador, Nepal, and Vietnam. Data were collected by mother interviews and child dental exams. Multivariate logistic and Zero-Inflated-Poisson regression analyses assessed associations between number of children, oral health practices and decayed, missing or filled teeth (dmft). Families had a mean of 2.2 children (range 1-12); 72% of children had tooth decay, with mean dmft of 5.4. Adjusting for child age, sex, and urban/rural location, a greater number of children in the family was associated with significantly less likelihood of unhealthy bottle feeding practices, having a toothbrush/toothpaste and parent helping child brush, and being cavity-free; higher number of dmft, and greater likelihood of having a dental visit. Early childhood oral health promotion should include focus on oral hygiene and healthy feeding-particularly breastfeeding and healthy bottle feeding practices-as well as access to family planning services and support for childcare.

RESUMEN

Tuberculosis is a disease caused by Mycobacterium tuberculosis, representing the second leading cause of death by an infectious agent worldwide. The available vaccine against this disease has insufficient coverage and variable efficacy, accounting for a high number of cases worldwide. In fact, an estimated third of the world's population has a latent infection. Therefore, developing new vaccines is crucial to preventing it. In this study, the highly antigenic PE_PGRS49 and PE_PGRS56 proteins were analyzed. These proteins were used for predicting T- and B-cell epitopes and for human leukocyte antigen (HLA) protein binding efficiency. Epitopes GGAGGNGSLSS, FAGAGGQGGLGG, GIGGGTQSATGLG (PE_PGRS49), and GTGWNGGKGDTG (PE_PGRS56) were selected based on their best physicochemical, antigenic, non-allergenic, and non-toxic properties and coupled to HLA I and HLA II structures for in silico assays. A construct with an adjuvant (RS09) plus each epitope joined by GPGPG linkers was designed, and the stability of the HLA-coupled construct was further evaluated by molecular dynamics simulations. Although experimental and in vivo studies are still necessary to ensure its protective effect against the disease, this study shows that the vaccine construct is dynamically stable and potentially effective against tuberculosis.

RESUMEN

This article reports the results of a study designed to explore the experiences and needs of family members for prognostic communication at end of life in an intensive care unit (ICU). Subjects in this qualitative study included 20 family members of patients at high risk for death in 1 adult medical/surgical ICU. All subjects were interviewed once utilizing a semistructured interview format, with approximately half interviewed multiple times during the ICU stay. Families described 5 themes of information-related "work": (1) hearing and recalling, (2) accessing, (3) interpreting, (4) retaining, and (5) utilizing information for decision making. Barriers, including accessing physicians and cognitive issues from high levels of stress, made this work difficult. Families described a need for prognostic information, especially if the prognosis was poor. Because hearing this news was difficult, they needed it communicated with respect, sensitivity, and compassion. Suggestions for clinical practice to support families in their information-related work are presented. Overall, the importance of providers approaching communication from a holistic perspective, extending beyond simply passing on information, is emphasized. Viewing communication as a therapeutic modality, and communicating with compassion, sensitivity, and a genuine sense of caring, can help provide both the information and the emotional support and comfort families desperately need.
