RESUMEN
OBJECTIVES: This study evaluated how high versus low-intensity community wellness coaching and health behaviors were associated with changes in depression screen results over one year. METHODS: This was an analysis of secondary data collected in a 12-month obesity-related community health worker (CHW) program for 485 Utah women of color. Depression screen (Patient Health Questionnaire-2 score ³3) and self-reported fruit/vegetable consumption and physical activity (FV/PA) were recorded quarterly. Associations between FV/PA and changes in depression screen over time were evaluated in multivariable models. RESULTS: Positive depression screen prevalence declined over 12 months (21.7% to 9.5%) with no difference between study arms. Overall, FV ³5 times/day (AOR=1.5; 95% CI 1.0-2.2), any PA (AOR=3.1; 95% CI 1.5-6.4), and muscle strengthening activities (AOR=1.13; 95% CI 1.01-1.26) were associated with improved depression screen results over time. CONCLUSION: These results indicate value in addressing and evaluating depression in obesity-related interventions in underserved communities.

Acceptance of the COVID-19 vaccination becomes more critical as new variants continue to evolve and the United States (US) attempts to move from pandemic response to management and control. COVID-19 stands out in the unique way it has polarized patients and generated sustained vaccine hesitancy over time. We sought to understand differences in perceptions and acceptance of COVID-19 vaccination between vaccine hesitant and non-hesitant patients, with the goal of informing communication and implementation strategies to increase uptake of COVID-19 vaccines in Veteran and non-Veteran communities. This qualitative study used interview data from focus groups conducted by the Department of Veterans Affairs (VA) and the University of Utah; all focus groups were conducted using the same script March-July 2021. Groups included forty-six United States Veterans receiving care at 28 VA facilities across the country and 166 non-Veterans across Utah for a total of 36 one-hour focus groups. We identified perceptions and attitudes toward COVID-19 vaccination through qualitative analysis of focus group participant remarks, grouping connections with identified themes within domains developed based on the questions asked in the focus group guide. Responses suggest participant attitudes toward the COVID-19 vaccine were shaped primarily by vaccine attitude changes over time, impacted by perceived vaccine benefits, risks, differing sources of vaccine information and political ideology. Veterans appeared more polarized, being either largely non-hesitant, or hesitant, whereas non-Veterans had a wider range of hesitancy, with more participants identifying minor doubts and concerns about receiving the vaccine, or simply being altogether unsure about receiving it. Development of COVID-19 vaccine communication strategies in Veteran and non-Veteran communities should anticipate incongruous sources of information and explicitly target community differences in perceptions of risks and benefits associated with the vaccine to generate candid discussions and repair individuals' trust. We believe this could accelerate vaccine acceptance over time.

Background: This study evaluated the discordance between Abbott Architect SARS-CoV-2 IgG and EUROIMMUN SARS-COV-2 ELISA in a seroprevalence study. Methods: From June 10 to August 15, 2020, 8,246 specimens were dually evaluated by the Abbott Architect SARS-CoV-2 IgG (Abbott) and the EUROIMMUN SARS-CoV-2 ELISA (EI) assays. Sex-stratified phi correlation coefficients were calculated to evaluate the concordance between Abbott and EI assay's quantitative results. Multivariable mixed-effect logistic models were implemented to evaluate the association between assay positivity and sex on a low prevalence sample while controlling for age, race, ethnicity, diabetes, cardiovascular disease, hypertension, immunosuppressive therapy, and autoimmune disease. Results: EI positivity among males was 2.1-fold that of females; however, no significant differences in Abbott positivity were observed between sexes. At the manufacturer-recommended threshold, the phi correlation coefficient for the Abbott and EI qualitative results among females (Φ = 0.47) was 34% greater than males (Φ = 0.35). The unadjusted and fully adjusted models yielded a strong association between sex and positive EI result for the low prevalence subgroup (unadjusted OR: 2.24, CI: 1.63, 3.11, adjusted OR: 3.40, CI: 2.15, 5.39). A similar analysis of Abbott positivity in the low prevalence subgroup did not find an association with any of the covariates examined. Significant quantitative and qualitative discordance was observed between Abbott and EI throughout the seroprevalence study. Our results suggest the presence of sex-associated specificity limitations with the EI assay. As these findings may extend to other anti-S assays utilized for SARS-CoV-2 seroprevalence investigations, further investigation is needed to evaluate the generalizability of these findings.

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.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) poses a high risk of transmission in close-contact indoor settings, which may include households. Prior studies have found a wide range of household secondary attack rates and may contain biases due to simplifying assumptions about transmission variability and test accuracy. METHODS: We compiled serological SARS-CoV-2 antibody test data and prior SARS-CoV-2 test reporting from members of 9,224 Utah households. We paired these data with a probabilistic model of household importation and transmission. We calculated a maximum likelihood estimate of the importation probability, mean and variability of household transmission probability, and sensitivity and specificity of test data. Given our household transmission estimates, we estimated the threshold of non-household transmission required for epidemic growth in the population. RESULTS: We estimated that individuals in our study households had a 0.41% (95% CI 0.32%- 0.51%) chance of acquiring SARS-CoV-2 infection outside their household. Our household secondary attack rate estimate was 36% (27%- 48%), substantially higher than the crude estimate of 16% unadjusted for imperfect serological test specificity and other factors. We found evidence for high variability in individual transmissibility, with higher probability of no transmissions or many transmissions compared to standard models. With household transmission at our estimates, the average number of non-household transmissions per case must be kept below 0.41 (0.33-0.52) to avoid continued growth of the pandemic in Utah. CONCLUSIONS: Our findings suggest that crude estimates of household secondary attack rate based on serology data without accounting for false positive tests may underestimate the true average transmissibility, even when test specificity is high. Our finding of potential high variability (overdispersion) in transmissibility of infected individuals is consistent with characterizing SARS-CoV-2 transmission being largely driven by superspreading from a minority of infected individuals. Mitigation efforts targeting large households and other locations where many people congregate indoors might curb continued spread of the virus.

We aimed to generate an unbiased estimate of the incidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in 4 urban counties in Utah, USA. We used a multistage sampling design to randomly select community-representative participants >12 years of age. During May 4-June 30, 2020, we collected serum samples and survey responses from 8,108 persons belonging to 5,125 households. We used a qualitative chemiluminescent microparticle immunoassay to detect SARS-CoV-2 IgG in serum samples. We estimated the overall seroprevalence to be 0.8%. The estimated seroprevalence-to-case count ratio was 2.5, corresponding to a detection fraction of 40%. Only 0.2% of participants from whom we collected nasopharyngeal swab samples had SARS-CoV-2-positive reverse transcription PCR results. SARS-CoV-2 antibody prevalence during the study was low, and prevalence of PCR-positive cases was even lower. The comparatively high SARS-CoV-2 detection rate (40%) demonstrates the effectiveness of Utah's testing strategy and public health response.

We use a community based participatory research approach to examine the processes of collaboration and communication, as well as the relational interactions of one community focused health promotion coalition, the Community Faces of Utah (CFU). We assess the evolution, structure, successes, and challenges of the coalition, comprised of five distinct cultural communities, a state health department, and a university. Researchers from the university collaborated with the coalition to find that CFU is an equitable, collaborative partnership of diverse leaders that functions successfully. Shared values and trusting relationships emerged over time, forming the basis for group interaction. A community liaison to facilitate interaction and collaboration was an essential element of the success of this partnership. The experience of CFU can guide other multi-sectoral partnerships in developing functionality consistent with achieving community driven objectives.
RESUMEN
Utah women from some cultural minority groups have higher overweight/obesity rates than the overall population. We utilized a gender-based mixed methods approach to learn about the underlying social, cultural and gender issues that contribute to the increased obesity risk among these women and to inform intervention development. A literature review and analysis of Utah's Behavioral Risk Factor Surveillance System data informed the development of a focus group guide. Focus groups were conducted with five groups of women: African immigrants from Burundi and Rwanda, African Americans, American Indians/Alaskan Natives, Hispanics/Latinas, and Pacific Islanders. Six common themes emerged: (1) health is multidimensional and interventions must address health in this manner; (2) limited resources and time influence health behaviors; (3) norms about healthy weight vary, with certain communities showing more preference to heavier women; (4) women and men have important but different influences on healthy lifestyle practices within households; (5) women have an influential role on the health of families; and (6) opportunities exist within each group to improve health. Seeking insights from these five groups of women helped to identify common and distinct cultural and gender themes related to obesity, which can be used to help elucidate core obesity determinants.

OBJECTIVES: To identify behavior theory-based strategies to improve compliance with daily multiple micronutrient supplementation (MMS) among rural Ghanaian women. METHODS: Components of a multi-theoretical framework were investigated in focus groups of reproductive-aged women in 6 communities. RESULTS: Participants were generally unaware of MMS' purpose. Perceived benefits included better health and stimulated appetite, which some believe escalates food purchases and financial constraints. Cost, forgetfulness, and unsustainability were also perceived barriers. Facilitators for compliance incorporated initial visual reminders and daily announcements with reinforcement using the 'keeper' system. CONCLUSIONS: Application of a tailored health behavioral model can effectively guide the design, implementation and evaluation of community-based MMS interventions.

AIM: Cardiovascular diseases (CVDs), of which hypertension is a major risk factor, are predicted to account for four times as many deaths as from communicable diseases by the year 2020. Hypertension, once rare, is rapidly becoming a major public health burden in sub-Saharan Africa (SSA). However, data on its prevalence, awareness, treatment and control are paltry, especially for rural communities. This study was done to determine the burden and correlates of adult hypertension in the rural Barekese sub-district of Ghana. METHODS: A cross-sectional survey was conducted on 425 adults aged ≥ 35 in the Barekese sub district (estimated population 18,510). Socio-demographic characteristics, modifiable and non-modifiable risk factors, blood pressure (BP) and anthropometric measurements were collected using standardized protocols. RESULTS: Overall, the proportion of hypertension and isolated systolic hypertension is 44.7% and 32.7% respectively in the study population. However, 64.9% of these were on treatment, with only 8.9% having controlled blood pressure (<140/90 mmHg). The mean systolic and diastolic BP were 134.38 mmHg (standard deviation, SD: 21.46) and 84.32 mmHg (SD: 12.44). Obesity (Body Mass Index, BMI>30 kg/m²) was found in 37 (10.4% of the population), out of whom 7 (15.9%) were extremely obese (BMI> 40 kg/m²). Increasing age and level of education were positively correlated with increasing blood pressure. CONCLUSION: The high burden of hypertension in this population along with the considerable less detection, treatment and control is of great concern. There is the need to promote health education measures that will foster prevention and early detection of hypertension.

Objectives. Disease surveillance combines data collection and analysis with dissemination of findings to decision makers. The timeliness of these activities affects the ability to implement preventive measures. Influenza surveillance has traditionally been hampered by delays in both data collection and dissemination. Methods. We used statistical process control (SPC) to evaluate the daily percentage of outpatient visits with a positive point-of-care (POC) influenza test in the University of Utah Primary Care Research Network. Results. Retrospectively, POC testing generated an alert in each of 4 seasons (2004-2008, median 16 days before epidemic onset), suggesting that email notification of clinicians would be 9 days earlier than surveillance alerts posted to the Utah Department of Health website. In the 2008-09 season, the algorithm generated a real-time alert 19 days before epidemic onset. Clinicians in 4 intervention clinics received email notification of the alert within 4 days. Compared with clinicians in 6 control clinics, intervention clinicians were 40% more likely to perform rapid testing (P = 0.105) and twice as likely to vaccinate for seasonal influenza (P = 0.104) after notification. Conclusions. Email notification of SPC-generated alerts provided significantly earlier notification of the epidemic onset than traditional surveillance. Clinician preventive behavior was not significantly different in intervention clinics.
RESUMEN
The period of adolescence is a critical time of development. There is an urgent need to better assess adolescent health worldwide, particularly in India, a country with the world's largest adolescent population. Validated screening tools are needed to evaluate health-related risks and behaviors in this growing demographic. We developed, validated and administered a school-based health assessment, the Indian Adolescent Health Questionnaire, which can be used as a comprehensive health-screening tool among Indian adolescents in secondary school.

OBJECTIVE: To assess the validity of the guinea pig as a model for congenital cytomegalovirus (CMV) infection by comparing the effectiveness of detecting the virus by real-time polymerase chain reaction (PCR) in blood, urine, and saliva. DESIGN: Case-control study. SETTING: Academic research. SUBJECTS: Eleven pregnant Hartley guinea pigs. MAIN OUTCOME MEASURES: Blood, urine, and saliva samples were collected from guinea pig pups delivered from pregnant dams inoculated with guinea pig CMV. These samples were then evaluated for the presence of guinea pig CMV by real-time PCR assuming 100% transmission. RESULTS: Thirty-one pups delivered from 9 inoculated pregnant dams and 8 uninfected control pups underwent testing for guinea pig CMV and for auditory brainstem response hearing loss. Repeated-measures analysis of variance demonstrated no statistically significantly lower weight for the infected pups compared with the noninfected control pups. Six infected pups demonstrated auditory brainstem response hearing loss. The sensitivity and specificity of the real-time PCR assay on saliva samples were 74.2% and 100.0%, respectively. The sensitivity of the real-time PCR on blood and urine samples was significantly lower than that on saliva samples. CONCLUSIONS: Real-time PCR assays of blood, urine, and saliva revealed that saliva samples show high sensitivity and specificity for detecting congenital CMV infection in guinea pigs. This finding is consistent with recent screening studies in human newborns. The guinea pig may be a good animal model in which to compare different diagnostic assays for congenital CMV infection.

BACKGROUND: Above-ground and underground nuclear weapon detonation at the Nevada Test Site (1951-1992) has resulted in radioiodine exposure for nearby populations. Although the long-term effect of environmental radioiodine exposure on thyroid disease has been well studied, little is known regarding the effect of childhood radioiodine exposure on subsequent fertility. OBJECTIVES: We investigated early childhood thyroid radiation exposure from nuclear testing fallout (supplied predominantly by radioactive isotopes of iodine) and self-reported lifetime incidence of male or female infertility or sterility. METHODS: Participants were members of the 1965 Intermountain Fallout Cohort, schoolchildren at the time of exposure who were reexamined during two subsequent study phases to collect dietary and reproductive histories. Thyroid radiation exposure was calculated via an updated dosimetry model. We used multivariable logistic regression with robust sandwich estimators to estimate odds ratios for infertility, adjusted for potential confounders and (in separate models) for a medically confirmed history of thyroid disease. RESULTS: Of 1,389 participants with dosimetry and known fertility history, 274 were classified as infertile, including 30 classified as sterile. Childhood thyroid radiation dose was possibly associated with infertility [adjusted odds ratio (AOR) = 1.17; 95% CI: 0.82, 1.67 and AOR = 1.35; 95% CI: 0.96, 1.90 for the middle and upper tertiles vs. the first tertile of exposure, respectively]. The odds ratios were attenuated (AOR = 1.08; 95% CI: 0.75, 1.55 and AOR = 1.29; 95% CI: 0.91, 1.83 for the middle and upper tertiles, respectively) after adjusting for thyroid disease. There was no association of childhood radiation dose and sterility. CONCLUSION: Our findings suggest that childhood radioiodine exposure from nuclear testing may be related to subsequent adult infertility. Further research is required to confirm this.

Plasma Plasmodium falciparum histidine-rich protein-2 (PfHRP-2) concentrations, a measure of parasite biomass, have been correlated with malaria severity in adults, but not yet in children. We measured plasma PfHRP-2 in Tanzanian children with uncomplicated (n = 61) and cerebral malaria (n = 45; 7 deaths). Median plasma PfHRP-2 concentrations were higher in cerebral malaria (1008 [IQR 342-2572] ng/mL) than in uncomplicated malaria (465 [IQR 36-1426] ng/mL; p = 0.017). In cerebral malaria, natural log plasma PfHRP-2 was associated with coma depth (r = -0.42; p = 0.006) and mortality (OR: 3.0 [95% CI 1.03-8.76]; p = 0.04). In this relatively small cohort study in a mesoendemic transmission area of Africa, plasma PfHRP-2 was associated with pediatric malaria severity and mortality. Further studies among children in areas of Africa with higher malaria transmission and among children with different clinical manifestations of severe malaria will help determine the wider utility of quantitative PfHRP-2 as a measure of parasite biomass and prognosis in sub-Saharan Africa.

PURPOSE: We evaluated our retrospective, single institution experience with high dose rate brachytherapy as monotherapy for intermediate risk prostate cancer. MATERIALS AND METHODS: Our cohort included 284 patients with intermediate risk prostate cancer, defined as clinical stage T2b/T2c, Gleason score 7 and/or prostate specific antigen 10 to 20 ng/ml, and 1-year minimum followup. Treatment was 2 high dose rate brachytherapy sessions at 3 fractions of 6.5 Gy each for a mean of 19 days. Prostate specific antigen failure was defined as nadir +2 ng/ml. RESULTS: Mean followup was 35.1 months (median 31.9). Actuarial 5-year cause specific survival and clinical local control were 100%, distant-metastasis-free survival 98.8% and biochemical disease-free survival 94.4%. Clinical stage predicted biochemical disease-free survival. For stage T2a or less 5-year biochemical disease-free survival was 95.1% vs 100% for stage T2b and 77.4% for T2c (p = 0.012). Percent positive biopsy cores and prostate specific antigen nadir were also predictive. International Prostate Symptom Score results remained stable and potency was maintained in 82.6% of patients at 2 years. Pads were used for the first time after brachytherapy in 22 patients (7.7%), mostly for grade 1 incontinence (occasionally or less per week). Excluding patients with prior transurethral prostatectomy, stroke or tremor 2.5% used pads for the first time after treatment. No patient had urethral stricture. Radiation Therapy Oncology Group grade 1 rectal toxicity developed in 12 patients (4.2%) but not beyond grade 1. CONCLUSIONS: High dose rate brachytherapy as monotherapy is safe and effective for patients with intermediate risk prostate cancer. We recommend caution for percent positive biopsy cores exceeding 75% or clinical stage T2c. Excluding such patients the 5-year biochemical disease-free survival rate was 97.5%.

Undernutrition is associated with poor cognitive development, late entry into school, decreased years of schooling, reduced productivity and smaller adult stature. We use longitudinal data from 1674 Peruvian children participating in the Young Lives study to assess the relative impact of early stunting (stunted at 6-18 months of age) and concurrent stunting (stunted at 4.5-6 years of age) on cognitive ability. Anthropometric data were longitudinally collected for children at 6-18 months of age and 4.5-6 years of age at which time verbal and quantitative ability were also assessed. We estimate that an increase in concurrent height-for-age z-scores (HAZ) by one standard deviation was associated with an increase in a child's score on the Peabody Picture Vocabulary Test (PPVT) by 2.35 points [confidence interval (CI): 1.55-3.15] and a 0.16 point increase on the cognitive development assessment (CDA) (CI: 0.05-0.27). Furthermore, we report that the estimate for concurrent HAZ and PPVT is significantly higher than the estimate for early stunting and PPVT. We found no significant difference between early and concurrent estimates for HAZ and CDA. Children from older mothers, children whose mothers had higher education levels, children living in urban areas, children who attended pre-school, children with fewer siblings and children from wealthier backgrounds scored higher on both assessments. Cognitive skills of children entering school were associated with early stunting but the strongest association was found with concurrent stunting suggesting that interventions preventing linear growth faltering should not only focus on the under 2s but include children up to 5 years of age.

BACKGROUND: Iodine deficiency is a major public health problem throughout Africa. Although salt for human consumption is said to contain adequate amounts of iodine in Uganda, iodine intake may not be optimal. We undertook a field study to assess the adequacy of iodine nutrition in western Uganda using on-site measurement methods of neonatal thyroid stimulating hormone (TSH) levels as recommended by the World Health Organization (WHO) for monitoring the degree of iodine deficiency during pregnancy. METHODS: The study design consisted of a prevalence study using the percentage of newborns between the ages of 3 and 7 days with TSH >5 mIU/L, measured with a point-of-care immunochromatographic TSH assay, as a surrogate marker of iodine deficiency. Five districts in western Uganda were selected for study on the basis of a past history of iodine deficiency. One thousand seventy-eight newborns from the five districts were sequentially enrolled in each separate district and tested between July 2007 and January 2008. RESULTS: The prevalence of TSH levels >5 mlU/L ranged from 20% to 32%. Neonates tested on or before the age of 3 days were more likely to have a TSH level >5 mlU/L than those tested beyond the age of three days (28.2% vs. 18.7%, p < 0.001). CONCLUSIONS: Assessing neonatal TSH levels in developing countries with a TSH assay method suitable for field use can be successfully used to screen for congenital hypothyroidism and to indirectly assess a population's iodine status. Based on the percentage of neonates with TSH values >5 mIU/L, presumptive iodine deficiency persists in western Uganda. This finding suggests that continued monitoring of iodine nutrition in the area surrounding the Rwenzori Mountains in Uganda and Congo is needed. Due to the progressive fall in the percent of TSH values >5 mIU/L from day three to day five of life, we conclude that TSH measurement earlier than day five of life in newborns at risk for iodine deficiency may be misleading. Guidelines for the use of neonatal TSH to monitor iodine nutrition should specify that TSH measurement take place no earlier than day five of life.

Osteoporosis represents a growing health burden, but recognition and screening rates are low. Electronic reminders for osteoporosis have been beneficial but are not based on clinical risk factors. Available risk screening tools may contain useful constructs for creating risk-based electronic medical record (EMR) reminders. Using a cohort study design among women ≥50 years with osteoporosis or osteoporosis risk, we searched the EMR for five World Health Organization (WHO) clinical risk factors including older age, lower body mass index (BMI), low bone mineral density (BMD), history of fracture since age 50, and maternal history of osteoporosis or fracture. Rates of reporting were lower than expected for BMD (6.8%), personal history of fracture (3.5%), and maternal history of fracture (0.3%). Despite the limitations, the EMR data were useful for identifying women at highest risk for fracture. Some evidence of bias in reporting rates was present. EMR data can be useful for identifying high fracture risk patients.
