Care groups in an integrated nutrition education intervention improved infant growth among South Sudanese refugees in Uganda's West Nile post-emergency settlements: A cluster randomized trial.

OBJECTIVE: This study examined the effects of a peer-led integrated nutrition education intervention with maternal social support using Care Groups on infant growth among South Sudanese refugees in Uganda. METHODS: A community-based cluster-randomized trial (RCT) was conducted among 390 pregnant women (third trimester). Two intervention study arms were Mothers-only(n = 131) and Parents-combined (n = 142) with a Control (n = 117). WHO infant growth standards defined length-for-age z-scores (LAZ) for stunting, weight-for-age z-scores (WAZ) for underweight and weight-for-length z-scores (WLZ) for wasting. The Medical Outcomes Study (MOS) social support index was a proxy measure for social support. A split-plot ANOVA tested the interaction effects of social support, intervention, and time on infant growth after adjusting for covariates. Further, pairwise comparisons explained mean differences in infant growth among the study arms. RESULTS: The mean infant birth weight was 3.1 ± 0.5 kg. Over the study period, infant stunting was most prevalent in the Control (≥ 14%) compared to Mothers-only (< 9.5%) and Parents-combined (< 7.4%) arms. There were significant interaction effects of the Care Group intervention and social support by time on infant mean LAZ (F (6, 560) = 28.91, p < 0.001), WAZ (F (5.8, 539.4) = 12.70, p = < 0.001) and WLZ (F (5.3, 492.5) = 3.38, p = 0.004). Simple main effects by the end of the study showed that the intervention improved infant mean LAZ (Mothers-only vs. Control (mean difference, MD) = 2.05, p < 0.001; Parents-combined vs. Control, MD = 2.00, p < 0.001) and WAZ (Mothers-only vs. Control, MD = 1.27, p < 0.001; Parents-combined vs. Control, MD = 1.28, p < 0.001). CONCLUSION: Maternal social support with an integrated nutrition education intervention significantly improved infant stunting and underweight. Nutrition-sensitive approaches focused on reducing child undernutrition among post-emergency refugees may benefit from using Care Groups in programs.

A Peer-Led Integrated Nutrition Education Intervention through Care Groups Improved Complementary Feeding of Infants in Postemergency Settlements in the West-Nile Region in Uganda: A Cluster Randomized Trial.

Background: Complementary feeding of infants in refugee settlements remains inadequate. Furthermore, there has been limited evaluation of interventions addressing these nutrition challenges. Objective: This study examined the effects of a peer-led integrated nutrition education intervention on infant complementary feeding by South Sudanese refugee mothers in the West-Nile region in Uganda. Methods: A community-based randomized trial enrolled 390 pregnant women (during third trimester) as the baseline. Two arms [mothers-only and parents-combined (both mothers and fathers)] comprised treatments with a control. Infant feeding was assessed using WHO and UNICEF guidelines. Data were collected at Midline-II and Endline. The medical outcomes study (MOS) social support index was used to measure social support. An overall mean score of >4 was considered optimal social support, a score of ≤2 was none or little support. Adjusted multivariable logistic regression models determined the effects of the intervention on infant complementary feeding. Results: At the end of the study, infant complementary feeding improved significantly in both mothers-only and parents-combined arms. There was a positive effect on the introduction of solid, semisolid, and soft foods (ISSSF) in the mothers-only arm at both Midline-II {adjusted odds ratio (AOR) = 4.0]} and Endline (AOR = 3.8). Likewise, ISSSF was better for the parents-combined arm at both Midline-II (AOR = 4.5) and Endline (AOR = 3.4). Minimum dietary diversity (MDD) was significantly better at the Endline for the parents-combined arm (AOR = 3.0). Minimum acceptable diet (MAD) was significantly better at Endline for both mothers-only (AOR = 2.3) and parents-combined arms (AOR = 2.7). Infant consumption of eggs and flesh foods (EFF) was improved only in the parents-combined arm at both Midline-II (AOR = 3.3) and Endline (AOR = 2.4). Higher maternal social support was associated with better infant MDD (AOR = 3.3), MAD (AOR = 3.6), and EFF (AOR = 4.7). Conclusion: Engaging both fathers and mothers in care groups benefited complementary feeding of infants. Overall, this peer-led integrated nutrition education intervention through care groups improved infant complementary feeding in the West-Nile postemergency settlements in Uganda.This trial was registered at clinicaltrials.gov as NCT05584969.

Breastfeeding among South Sudanese refugees in protracted settlements in Adjumani district, Uganda: facilitators and barriers.

BACKGROUND: Evidence suggests that forced migration and refugee status may adversely impact mothers' breastfeeding choices. Furthermore, suboptimal breastfeeding practices have been reported among vulnerable populations including those living in refugee settlements. Therefore, this study investigated the barriers and facilitators of breastfeeding in protracted settlements in Adjumani district, in the West Nile region in Uganda. METHODS: This study was conducted among refugees living in protracted settlements located in Uganda in July 2019. Participants, originally from South Sudan, included mothers (n = 63) and fathers (n = 32) of children less than 24 months of age. Agojo, Ayilo-I, and Nyumanzi were randomly selected among the 17 refugee settlements in Adjumani. Participants formed a total of six focus group discussions (FGDs); four FGDs for mothers and two FGDs for fathers. Each FGD consisted of 15-16 participants. Data were transcribed verbatim and back-translated into English. Thematic analysis was used and data were analyzed using NVivo, v. 12. RESULTS: Facilitators of breastfeeding included knowledge of breastfeeding benefits, support from husband/father, support from the community, and support from non-governmental organizations. Mothers and fathers noted that breastfeeding protected children from diseases and breastfed children grew well. Fathers, the community, and organizations provided material support for breastfeeding mothers. Four themes were identified as barriers to breastfeeding: physical, socioeconomic, knowledge, and psychosocial. Mothers and fathers described physical barriers such as mothers stop breastfeeding when they are sick or they feel they are not producing enough breastmilk. Mothers reported that working or educated mothers may use other milk to feed their infant. Some mothers and fathers believed infants under six months needed more than breastmilk. Fathers described psychosocial barriers such as mothers' fear of pain during breastfeeding and maternal mental health issues. CONCLUSION: Interventions and policies that aim to improve breastfeeding in protracted settlements should consider addressing the barriers to breastfeeding at each level: physical, socioeconomic, knowledge, and psychosocial. Involving and encouraging support from husbands/fathers, relatives, and the community may increase adherence to breastfeeding recommendations.

The associations between women's empowerment measures, child growth and dietary diversity: Findings from an analysis of demographic and health surveys of seven countries in Eastern Africa.

Evidence on the efficacy of women's empowerment to improve child growth and minimum dietary diversity (MDD) in the Eastern Africa (EA) region is limited. This cross-sectional study used recent Demographic and Health Survey data of mother-child dyads from seven countries in EA to examine the associations between women's empowerment measures, child growth and MDD. Length-for-age z-scores, weight-for-length z-scores and weight-for-age z-scores were used to categorize growth indicators of 6-23 months old children. Multivariable logistic regression was used to identify significant associations. Among all countries, 32%-59% of children experienced growth failure. Children meeting MDD were 18%-45%. Women having self-esteem were associated with lower odds of stunting (adjusted odds ratio [AOR] = 0.62 in Rwanda), wasting (AOR = 0.38 in Uganda), underweight (AORs = 0.60 and 0.57 in Tanzania and Uganda, respectively) and growth failure (AOR = 0.64 in Rwanda). Having health decision control in Burundi was associated with lower odds of stunting (AOR = 0.49) and child growth failure (AOR = 0.52) and higher odds of meeting MDD (AOR = 2.50). Having Legal empowerment among women increased the odds of stunting (AOR = 1.79 in Burundi), underweight (AOR = 1.77 in Uganda) and growth failure (AOR = 1.87 in Burundi). Economic empowerment showed mixed associations with child growth and MDD among some countries. Women's self-esteem and health decision control were associated with better child growth and MDD for some countries in EA. Nutrition-sensitive interventions aimed at improving child growth and MDD should consider local contexts when addressing women's empowerment.

Coping With COVID-19: Health Risk Communication and Vulnerable Groups.

OBJECTIVES: This study sought to identify coronavirus disease 2019 (COVID-19) risk communication materials distributed in Jamaica to mitigate the effects of the disease outbreak. It also sought to explore the effects of health risk communication on vulnerable groups in the context of the pandemic. METHODS: A qualitative study was conducted, including a content analysis of health risk communications and in-depth interviews with 35 purposively selected elderly, physically disabled, persons with mental health disorders, representatives of government agencies, advocacy and service groups, and caregivers of the vulnerable. Axial coding was applied to data from the interviews, and all data were analyzed using the constant comparison technique. RESULTS: Twelve of the 141 COVID-19 risk communication messages directly targeted the vulnerable. All participants were aware of the relevant risk communication and largely complied. Barriers to messaging awareness and compliance included inappropriate message medium for the deaf and blind, rural location, lack of Internet service or digital devices, limited technology skills, and limited connection to agencies that serve the vulnerable. CONCLUSION: The vulnerable are at increased risk in times of crisis. Accessibility of targeted information was inadequate for universal access to health information and support for vulnerable persons regardless of location and vulnerability.

Fathers' involvement in child care activities: Qualitative findings from the highlands of Madagascar.

Few studies have investigated fathers' roles in child care in Madagascar. This study explored the perceptions, attitudes, and practices regarding fathers' involvement in child care using qualitative methods. Ten focus group discussions were conducted among parents of children aged 6-23 months; seven were among mothers, and three among fathers. In-depth semi-structured interviews (n = 8) were also conducted with key informants. Discussions and interviews were audio-recorded and the verbatim transcripts in Malagasy were translated into English. Data were analyzed using the thematic analysis approach. Provision of financial and material support as well as teaching and playing with the child were the main perceived roles of fathers. In practice, fathers spent their time alone with their children playing and holding them when the mother was unavailable. Busy schedules and separation due to work were major barriers to fathers' involvement. Traditional gender roles for child care in which the mother is seen as primarily responsible for the child were salient across the data. Consequently, men involved in child care activities and their wives were often criticized by the community. Nevertheless, there was self-reported interest from both mothers and fathers in involving men more in child care. Interventions aimed to increase fathers' involvement in child care may be more successful when they focus on shifting the community perceptions on the division of responsibilities between fathers and mothers.

Maternal experience of intimate partner violence is associated with suboptimal breastfeeding practices in Malawi, Tanzania, and Zambia: insights from a DHS analysis.

BACKGROUND: Despite widespread suboptimal breastfeeding practices and maternal experiences of intimate partner violence (IPV), the association of IPV and breastfeeding practices remains unclear. This study investigated the associations between maternal experience of physical, sexual, emotional violence, and controlling behaviors with suboptimal breastfeeding practices in Malawi, Tanzania, and Zambia. METHODS: Data included mother-infant dyads from the most recent Demographic and Health Surveys for Malawi (n = 1878), Tanzania (n = 3184), and Zambia (n = 3879). Intimate partner violence (physical, sexual, and emotional) was measured using the Revised Conflict Tactics Scale. Breastfeeding practices were early initiation of breastfeeding (within 1 h of birth), exclusive breastfeeding (in previous 24 h), and continued breastfeeding. Associations between experience of physical, sexual, or emotional violence or controlling behaviors and breastfeeding practices, as well as associations between the frequency of IPV and breastfeeding practices were assessed. RESULTS: Many Malawian (77.6%) and Zambian (67.7%) and just over half (53.6%) of Tanzanian mothers, initiated breastfeeding within 1 h of birth. Exclusive breastfeeding was 70.6% in Zambia and 60.1% in Malawi, while 55.0% of Tanzanian mothers breastfed exclusively. Continued breastfeeding to at least 1 year was high in Malawi 92.2%, Tanzania 93.4%, and Zambia 95.0%. Most mothers reported experiences of IPV in Tanzania 79.1%, Zambia 78.9%, and Malawi 73.9%. Mothers who experienced sexual IPV were significantly more likely to delay breastfeeding (Malawi [AOR 1.55 (1.14, 2.10)]; Tanzania [AOR 1.30 (1.04, 1.62)]; and Zambia [AOR 1.28 (1.06, 1.54)]). Sexual IPV in Malawi and Zambia was associated with greater odds of not exclusively breastfeeding (Malawi [AOR 1.90 (1.05, 3.45)]; Zambia [AOR 1.75 (1.15, 2.67)]). Tanzanian mothers who experienced IPV often or sometimes were two times more likely not to breastfeed at one-year post-delivery [AOR 2.23 (1.09,4.57)]. CONCLUSIONS: In the three countries investigated maternal experience of IPV was associated with suboptimal breastfeeding practices. Policies and programs targeting improved breastfeeding practices should consider screening during antenatal and postnatal care for experience of violence and support initiatives to reduce IPV.

The WHO and UNICEF Joint Monitoring Programme (JMP) Indicators for Water Supply, Sanitation and Hygiene and Their Association with Linear Growth in Children 6 to 23 Months in East Africa.

The slow decrease in child stunting rates in East Africa warrants further research to identify the influence of contributing factors such as water, sanitation, and hygiene (WASH). This study investigated the association between child length and WASH conditions using the recently revised WHO and UNICEF (United Nations Children's Fund) Joint Monitoring Programme (JMP) indicators. Data from households with infants and young children aged 6-23 months from the Demographic and Health Surveys in Burundi, Ethiopia, Kenya, Malawi, Rwanda, Tanzania, Uganda, and Zambia were used. Associations for each country between WASH conditions and length-for-age z-scores (LAZ) were analyzed using linear regression. Stunting rates were high (>20%) reaching 45% in Burundi. At the time of the most recent Demographic and Health Survey (DHS), more than half of the households in most countries did not have basic or safely managed WASH indicators. Models predicted significantly higher LAZ for children living in households with safely managed drinking water compared to those living in households drinking from surface water in Kenya (ß = 0.13, p < 0.01) and Tanzania (ß = 0.08, p < 0.05) after adjustment with child, maternal, and household covariates. Children living in households with improved sanitation facilities not shared with other households were also taller than children living in households practicing open defecation in Ethiopia (ß = 0.07, p < 0.01) and Tanzania (ß = 0.08, p < 0.01) in the adjusted models. All countries need improved WASH conditions to reduce pathogen and helminth contamination. Targeting adherence to the highest JMP indicators would support efforts to reduce child stunting in East Africa.

Community Engagement Mental Health Model for Home Treatment of Psychosis in Jamaica.

Economic constraints in low- and middle-income countries like Jamaica challenge health care services to identify efficient methods of mental health care. This column describes the community engagement mental health (CEMH) model in Kingston, Jamaica, for patients with mental disorders, including psychosis. The CEMH uses a task sharing methodology to deliver acute psychiatric treatment within a community setting. Preliminary results suggest high service user and provider satisfaction and good clinical outcomes. The authors discuss challenges and benefits of the CEMH in terms of its potential as a cost-effective service innovation.

The SmoCar Study: A Caribbean-Based Multicenter Study on the Prevalence and Disparities Linked to Smoking and Gingival Health.

The aim of the SmoCar (Smoking in the Caribbean) study was to estimate the prevalence of smoking and the disparities in the smoking practices of three regions in the Caribbean: Jamaica, Dominican Republic, and Puerto Rico. The secondary objective was to assess the prevalence and severity of gingivitis in relation to the smoking practices. The study population comprised 1,847 (weighted N = 1,830) individuals (18 years and older) who were volunteer participants from the capitals of Jamaica, Dominican Republic, and Puerto Rico. A structured interview was used to assess the participants' smoking behaviors. The gingival index was used to determine the extent of gingival inflammation. Polytomous regression was used to estimate the adjusted odds ratios (aORs) for smoking status (current, past, or never), according to risk factors (sex, age-group, education, marital status, tooth-brushing frequency, and city of residence). Logistic regression models were used to assess the associations between different smoking status variables and mild to moderate/severe gingivitis. The majority of the participants were never-smokers, with current smokers being found most commonly in Kingston (33.22%), followed by San Juan (12.76%) and Santo Domingo (8.8%). Both current (aOR = 2.22, 95% confidence interval [1.45, 3.40]) and past (aOR = 1.87, 95% confidence interval [1.19, 2.93]) smoking (vs. never smoking) was strongly associated with severe gingivitis. Smoking was the most prevalent in Jamaicans and the least prevalent in Dominicans. The study population of current smokers was found to have a fourfold increased risk of severe gingivitis and a twofold increased risk of moderate gingivitis.

Maternal determinants of optimal breastfeeding and complementary feeding and their association with child undernutrition in Malawi (2015-2016).

BACKGROUND: Optimal breastfeeding and complementary feeding practices are critical to prevent child undernutrition. Despite the occurrence of child undernutrition and widespread suboptimal feeding practices in Malawi, the association of breastfeeding and complementary feeding practices and undernutrition among Malawian children remains unclear. The purpose of the study was to determine the current breastfeeding and complementary feeding practices, to identify maternal determinants of each practice, and to analyze the associations between breastfeeding and complementary feeding practices with stunting, underweight, and wasting. METHODS: The most recent Malawi Demographic Health Survey (2015-2016) was used and data for 2294 children aged 0-23 months were included. A conceptual framework of five maternal domains: sociodemographic, health status, health behaviors, women's empowerment, and media exposure was used. Each domain contained exposure variables and the WHO Infant and Young Child Feeding indicators were used as outcome variables. All analyses were adjusted for clustering, and variables that reached a p-value of < 0.05 were considered significant in the final model. RESULTS: Among children, 30.8% were stunted, 9.9% were underweight, and 3.7% were wasted. Many (78%) were breastfed within the first hour of birth, 89% were breastfed until their first birthday, yet 40% were not exclusively breastfed to 6 months. Only 32% met minimum dietary diversity, 23% met minimum meal frequency, 12% met minimum acceptable diet and 12% consumed iron-rich foods. Children whose mothers lived in urban areas were less likely to be breastfed within 1 hour of birth but more likely to meet minimum dietary diversity. Children whose mothers listened to radio were more likely to meet minimum meal frequency. Children (13-23 months) who met minimum meal frequency and minimum acceptable diet were less likely to be underweight. CONCLUSIONS: Optimal breastfeeding and complementary feeding practices in Malawi remain suboptimal and child undernutrition remains problematic. Maternal characteristics from the five domains were significantly associated with optimal breastfeeding and complementary feeding indicators. Knowledge of these maternal determinants can assist in improving nutrition policies and interventions that aim to impact breastfeeding and complementary feeding practices and child growth in Malawi.

Infectious disease morbidity and growth among young HIV-exposed uninfected children in Jamaica / Morbilidad por enfermedades infecciosas y crecimiento en niños pequeños no infectados pero expuestos al VIH en Jamaica

ABSTRACT Objective There is a growing body of data that demonstrates increased infectious disease outcomes for HIV-exposed uninfected (HIV-EU) infants as compared to their HIV-unexposed (HU) counterparts. We hypothesized that these HIV-EU infants are at greater risk for infectious morbidity and mortality when compared to the general childhood population. We therefore aimed to characterize infections and growth outcomes among HIV-EU infants in Jamaica during their first two years of life. By identifying these outcomes, specific interventions could be implemented to mitigate this risk of morbidity and mortality. Methods HIV-EU infants born between 1 January 2004 and 31 December 2006 in Kingston, Jamaica, were enrolled and followed in multicenter health facilities, using standardized protocols. HIV status was determined by RNA/DNA polymerase chain reaction (PCR) and confirmatory HIV enzyme-linked immunoassay (ELISA). Data were collected on demographic and anthropometric characteristics, infectious morbidity and mortality, and hospitalizations. Outcomes (incidence of infections and hospitalizations; growth (z scores for weight)) were determined, using univariate analyses. Results Of 195 HIV-EU infants followed for 25.9 months (standard deviation, 10.9 months), 102 (52%) were male, 185 (95%) were non-breast-fed, 161 (83%) experienced at least one infection, and 58 (30%) were hospitalized at least once. Infectious disease incidence per 1 000 child-weeks included upper respiratory tract infection of 7.25 (95% confidence interval (CI): 5.92–8.90), otitis media of 4.12 (3.21–5.20), and acute gastroenteritis (AGE) of 1.92 (1.35–2.65). Hospitalization incidence per 1 000 child-weeks included lower respiratory tract infections (LRTIs) of 0.89 (0.53–1.40), sepsis of 0.48 (0.23–0.89), and AGE of 0.43 (0.20–0.81). These infection incidence rates among the HIV-EU infants were higher than those for published community controls. Among the HIV-EU infants, the low-birthweight ones and those born via cesarean section had significantly higher hospitalization rates from LRTI and sepsis than did published community controls. The mean z score for weight during the infants’ first 6 months ranged from -0.06 to 0.78 in this predominantly non-breast-fed population. That score trended upwards to 24 months of age. Conclusions Infectious disease morbidity was higher but growth was normal in this cohort of HIV-EU non-breast-fed infants, in comparison to published community controls. Specific interventions should be implemented to mitigate the risk in this setting.

La incidencia de enfermedades infecciosas por 1 000 niño-semanas incluyó infecciones de las vías respiratorias superiores de 7,25 (intervalo de confianza [IC] de 95%: 5,92–8,90), otitis media de 4,12 (3,21–5,20) y gastroenteritis aguda (AGE) de 1,92 (1,35–2,65). La incidencia de hospitalización por 1 000 niño-semanas incluyó infecciones de las vías respiratorias inferiores de 0,89 (0,53–1,40), septicemia de 0,48 (0,23–0,89) y gastroenteritis aguda de 0,43 (0,20–0,81). Estas tasas de incidencia de infecciones en los lactantes no infectados pero expuestos fueron más altas que las de los controles comunitarios publicados. En los lactantes no infectados pero expuestos, aquellos con peso bajo al nacer y aquellos nacidos por cesárea registraron tasas de hospitalización significativamente más altas por infecciones de las vías respiratorias inferiores y septicemia que los controles comunitarios publicados. La media de la puntuación z para el peso durante los 6 primeros meses de los lactantes se ubicó entre -0,06 y 0,78 en esta población que en su mayoría no fue amamantada.

Conclusiones La morbilidad por enfermedades infecciosas fue mayor, pero el crecimiento fue normal en esta cohorte de lactantes no infectados pero expuestos al VIH y no amamantados, en comparación con los controles comunitarios publicados. Deben realizarse intervenciones específicas para mitigar el riesgo en este entorno.

Data were collected on demographic and anthropometric characteristics, infectious morbidity and mortality, and hospitalizations. Outcomes (incidence of infections and hospitalizations; growth (z scores for weight)) were determined, using univariate analyses. RESULTS: Of 195 HIV-EU infants followed for 25.9 months (standard deviation, 10.9 months), 102 (52%) were male, 185 (95%) were non-breast-fed, 161 (83%) experienced at least one infection, and 58 (30%) were hospitalized at least once. Infectious disease incidence per 1 000 child-weeks included upper respiratory tract infection of 7.25 (95% confidence interval (CI): 5.92-8.90), otitis media of 4.12 (3.21-5.20), and acute gastroenteritis (AGE) of 1.92 (1.35-2.65). Hospitalization incidence per 1 000 child-weeks included lower respiratory tract infections (LRTIs) of 0.89 (0.53-1.40), sepsis of 0.48 (0.23-0.89), and AGE of 0.43 (0.20-0.81). These infection incidence rates among the HIV-EU infants were higher than those for published community controls. Among the HIV-EU infants, the low-birthweight ones and those born via cesarean section had significantly higher hospitalization rates from LRTI and sepsis than did published community controls. The mean z score for weight during the infants' first 6 months ranged from -0.06 to 0.78 in this predominantly non-breast-fed population. That score trended upwards to 24 months of age. CONCLUSIONS: Infectious disease morbidity was higher but growth was normal in this cohort of HIV-EU non-breast-fed infants, in comparison to published community controls. Specific interventions should be implemented to mitigate the risk in this setting.

Infection control practice in the operating room: staff adherence to existing policies in a developing country.

CONTEXT: Infection control interventions are important for containing surgery-related infections. For this reason, the modern operating room (OR) should have well-developed infection control policies. The efficacy of these policies depends on how well the OR staff adhere to them. There is a lack of available data documenting adherence to infection control policies. OBJECTIVE: To evaluate OR staff adherence to existing infection control policies in Jamaica. METHODS: We administered a questionnaire to all OR staff to assess their training, knowledge of local infection control protocols, and practice with regard to 8 randomly selected guidelines. Adherence to each guideline was rated with fixed-choice items on a 4-point Likert scale. The sum of points determined the adherence score. Two respondent groups were defined: adherent (score > 26) and nonadherent (score ≤ 26). We evaluated the relationship between respondent group and age, sex, occupational rank, and time since completion of basic medical training. We used χ(2) and Fisher exact tests to assess associations and t tests to compare means between variables of interest. RESULTS: The sample comprised 132 participants (90 physicians and 42 nurses) with a mean age of 36 (standard deviation ± 9.5) years. Overall, 40.1% were adherent to existing protocols. There was no significant association between the distribution of adherence scores and sex (p = 0.319), time since completion of basic training (p = 0.595), occupational rank (p = 0.461), or age (p = 0.949).Overall, 19% felt their knowledge of infection control practices was inadequate. Those with working knowledge of infection control practices attained it mostly through informal communication (80.4%) and self-directed research (62.6%). CONCLUSION: New approaches to the problem of nonadherence to infection control guidelines are needed in the Caribbean. Several unique cultural, financial, and environmental factors influence adherence in this region, in contrast to conditions in developed countries.

Mind the gap: racial differences in breast cancer incidence and biologic phenotype, but not stage, among low-income women participating in a government-funded screening program.

Breast cancer mortality rates in South Carolina (SC) are 40 % higher among African-American (AA) than European-American (EA) women. Proposed reasons include race-associated variations in care and/or tumor characteristics, which may be subject to income effects. We evaluated race-associated differences in tumor biologic phenotype and stage among low-income participants in a government-funded screening program. Best Chance Network (BCN) data were linked with the SC Central Cancer Registry. Characteristics of breast cancers diagnosed in BCN participants aged 47-64 years during 1996-2006 were abstracted. Race-specific case proportions and incidence rates based on estrogen receptor (ER) status and histologic grade were estimated. Among 33,880 low-income women accessing BCN services, repeat breast cancer screening utilization was poor, especially among EAs. Proportionally, stage at diagnosis did not differ by race (607 cancers, 53 % among AAs), with about 40 % advanced stage. Compared to EAs, invasive tumors in AAs were 67 % more likely (proportions) to be of poor-prognosis phenotype (both ER-negative and high-grade); this was more a result of the 46 % lesser AA incidence (rates) of better-prognosis (ER+ lower-grade) cancer than the 32 % greater incidence of poor-prognosis disease (p values <0.01). When compared to the general SC population, racial disparities in poor-prognostic features within the BCN population were attenuated; this was due to more frequent adverse tumor features in EAs rather than improvements for AAs. Among low-income women in SC, closing the breast cancer racial and income mortality gaps will require improved early diagnosis, addressing causes of racial differences in tumor biology, and improved care for cancers of poor-prognosis biology.

Prevalence of gastrointestinal symptoms among ambulatory HIV patients and a control population.

BACKGROUND: The gastrointestinal tract is a common site of involvement in HIV-infected patients. Gastrointestinal symptoms are common in the general population and are associated with decreased quality of life. METHODS: Ambulatory consecutive HIV-infected patients and consecutive healthy blood donors seen in Jamaica were studied. A 19-item questionnaire of GI symptoms was administered. RESULTS: There were 196 respondents. Among 99 HIV patients, the mean number of symptoms was 2.9 and in 97 controls 3.3 (p=0.091). Dysphagia and odynophagia were present in 8.1% of HIV patients and 3.1% of the controls (p=0.129). Belching was present in 59.6% of HIV patients and in 96.8% of controls (p≤0.001). In the control group, 44.3% had heartburn compared to 29.3% of HIV patients. Within the preceding year, 26.3% of HIV participants and 12.4% of controls sought medical attention for their GI symptoms (p=0.001). GI symptomatology was directly related to immune status in the HIV group as patients with a CD4 count of less than 200 cells/µL reported up to 6 GI symptoms, those with CD4 of 201-350 cells/µL had 3 symptoms, and patients with CD4 greater than 351 cells/µL had 1 symptom. Pain on swallowing, and vomiting were significantly more common in patients with CD4 <350 cells/µL than in controls. CONCLUSIONS: GI symptoms were common in HIV patients and controls. In HIV patients symptoms were directly related to CD4 count. Pain on swallowing and vomiting were significantly more common in patients with CD4 <350 cells/µL than in controls.

Plasma Renin test-guided drug treatment algorithm for correcting patients with treated but uncontrolled hypertension: a randomized controlled trial.

BACKGROUND: Undefined pathophysiologic mechanisms likely contribute to unsuccessful antihypertensive drug therapy. The renin test-guided therapeutic (RTGT) algorithm is based on the concept that, irrespective of current drug treatments, subnormal plasma renin activity (PRA) (<0.65 ng/ml/h) indicates sodium-volume excess "V" hypertension, whereas values >or=0.65 indicate renin-angiotensin vasoconstriction excess "R" hypertension. METHODS: The RTGT algorithm was applied to treated, uncontrolled hypertensives and compared to clinical hypertension specialists' care (CHSC) without access to PRA. RTGT protocol: "V" patients received natriuretic anti-"V" drugs (diuretics, spironolactone, calcium antagonists, or alpha(1)-blockers) while withdrawing antirenin "R" drugs (converting enzyme inhibitors, angiotensin receptor antagonists, or beta-blockers). Converse strategies were applied to "R" patients. Eighty-four ambulatory hypertensives were randomized and 77 qualified for the intention-to-treat analysis including 38 in RTGT (63.9 +/- 1.8 years; baseline blood pressure (BP) 157.0 +/- 2.6/87.1 +/- 2.0 mm Hg; PRA 5.8 +/- 1.6; 3.1 +/- 0.3 antihypertensive drugs) and 39 in CHSC (58.0 +/- 2.0 years; BP 153.6 +/- 2.3/91.9 +/- 2.0; PRA 4.6 +/- 1.1; 2.7 +/- 0.2 drugs). RESULTS: BP was controlled in 28/38 (74% (RTGT)) vs. 23/39 (59% (CHSC)), P = 0.17, falling to 127.9 +/- 2.3/73.1 +/- 1.8 vs. 134.0 +/- 2.8/79.8 +/- 1.9 mm Hg, respectively. Systolic BP (SBP) fell more with RTGT (-29.1 +/- 3.2 vs. -19.2 +/- 3.2 mm Hg, P = 0.03), whereas diastolic BP (DBP) declined similarly (P = 0.32). Although final antihypertensive drug numbers were similar (3.1 +/- 0.2 (RTGT) vs. 3.0 +/- 0.3 (CHSC), P = 0.73) in "V" patients, 60% (RTGT) vs. 11% (CHSC) of "R" drugs were withdrawn and BP medications were reduced (-0.5 +/- 0.3 vs. +0.7 +/- 0.3, P = 0.01). CONCLUSIONS: In treated but uncontrolled hypertension, RTGT improves control and lowers BP equally well or better than CHSC, indicating that RTGT provides a reasonable strategy for correcting treated but uncontrolled hypertension.

Blood transfusion practices in total joint arthroplasties in Jamaica.

BACKGROUND: Major blood loss usually occurs in both hip and knee arthroplasty, frequently leading to the need for blood transfusion. This study was performed to determine blood transfusion rates and analyze the factors which affected the need for blood transfusion in patients who underwent primary unilateral total knee and hip arthroplasties at the University Hospital of the West Indies, Jamaica. METHODS: A prospective study of 118 patients who underwent unilateral total knee and total hip arthroplasties between January 2004 and July 2009 was undertaken. Data collected was analyzed using Microsoft Excel 2008, SPSS version 12 and Stata version 7.0. RESULTS: Of the 118 patients, 90 (70%) were females. Mean ± standard deviation (SD) age was 65.2 ± 11.5 years (range 32 - 85 years). Osteoarthritis accounted for the majority (88%) of arthroplasties. Mean ± SD estimated blood loss for all arthroplasties was 1195.0 ± 855.6 ml (range 100 - 6000 ml). Mean ± SD duration of surgery for all joint arthroplasties was 226.1 ± 63.5 minutes (range 110 - 392 minutes). Mean ± SD preoperative hemoglobin was 12.09 g/dl (range 7.3 - 15.6 g/dl). Average body mass index was 28.9 kg/m(2) (range 17.9 - 68.3 kg/m(2)). Seventy-five (64%) patients were transfused and of these, 44 patients received allogenic blood only; 20 patients received autologous blood only, and eleven patients received both allogenic and autologous blood.  The overall blood transfusion rate was 63%. CONCLUSION: In our study, the multivariate analysis showed a significant relationship (p = 0.000) only between postoperative transfusion and the estimated blood loss. KEYWORDS: Blood transfusion practices; Total joint arthroplasties.

Factors affecting study efficiency and item non-response in health surveys in developing countries: the Jamaica national healthy lifestyle survey.

BACKGROUND: Health surveys provide important information on the burden and secular trends of risk factors and disease. Several factors including survey and item non-response can affect data quality. There are few reports on efficiency, validity and the impact of item non-response, from developing countries. This report examines factors associated with item non-response and study efficiency in a national health survey in a developing Caribbean island. METHODS: A national sample of participants aged 15-74 years was selected in a multi-stage sampling design accounting for 4 health regions and 14 parishes using enumeration districts as primary sampling units. Means and proportions of the variables of interest were compared between various categories. Non-response was defined as failure to provide an analyzable response. Linear and logistic regression models accounting for sample design and post-stratification weighting were used to identify independent correlates of recruitment efficiency and item non-response. RESULTS: We recruited 2012 15-74 year-olds (66.2% females) at a response rate of 87.6% with significant variation between regions (80.9% to 97.6%; p < 0.0001). Females outnumbered males in all parishes. The majority of subjects were recruited in a single visit, 39.1% required multiple visits varying significantly by region (27.0% to 49.8% [p < 0.0001]). Average interview time was 44.3 minutes with no variation between health regions, urban-rural residence, educational level, gender and SES; but increased significantly with older age category from 42.9 minutes in the youngest to 46.0 minutes in the oldest age category. Between 15.8% and 26.8% of persons did not provide responses for the number of sexual partners in the last year. Women and urban residents provided less data than their counterparts. Highest item non-response related to income at 30% with no gender difference but independently related to educational level, employment status, age group and health region. Characteristics of non-responders vary with types of questions. CONCLUSION: Informative health surveys are possible in developing countries. While survey response rates may be satisfactory, item non-response was high in respect of income and sexual practice. In contrast to developed countries, non-response to questions on income is higher and has different correlates. These findings can inform future surveys.
