RESUMO

Importance: Black and Hispanic patients have high rates of recurrent stroke and uncontrolled hypertension in the US. The effectiveness of home blood pressure telemonitoring (HBPTM) and telephonic nurse case management (NCM) among low-income Black and Hispanic patients with stroke is unknown. Objective: To determine whether NCM plus HBPTM results in greater systolic blood pressure (SBP) reduction at 12 months and lower rate of stroke recurrence at 24 months than HBPTM alone among Black and Hispanic stroke survivors with uncontrolled hypertension. Design, Setting, and Participants: Practice-based, multicenter, randomized clinical trial in 8 stroke centers and ambulatory practices in New York City. Black and Hispanic study participants were enrolled between April 18, 2014, and December 19, 2017, with a final follow-up visit on December 31, 2019. Interventions: Participants were randomly assigned to receive either HBPTM alone (12 home BP measurements/week for 12 months, with results transmitted to a clinician; n = 226) or NCM plus HBPTM (20 counseling calls over 12 months; n = 224). Main Outcomes and Measures: Primary outcomes were change in SBP at 12 months and rate of recurrent stroke at 24 months. Final statistical analyses were completed March 14, 2024. Results: Among 450 participants who were enrolled and randomized (mean [SD] age, 61.7 [11.0] years; 51% were Black [n = 231]; 44% were women [n = 200]; 31% had ≥3 comorbid conditions [n = 137]; 72% had household income <$25 000/y [n = 234/324]), 358 (80%) completed the trial. Those in the NCM plus HBPTM group had a significantly greater SBP reduction than those in the HBPTM alone group at 12 months (-15.1 mm Hg [95% CI, -17.2 to -13.0] vs -5.8 mm Hg [95% CI, -7.9 to -3.7], respectively; P < .001). The between-group difference in SBP reduction at 12 months, adjusted for primary care physician clustering, was -8.1 mm Hg (95% CI, -11.2 to -5.0; P < .001) at 12 months. The rate of recurrent stroke was similar between both groups at 24 months (4.0% in the NCM plus HBPTM group vs 4.0% in the HBPTM alone group, P > .99). Conclusions and Relevance: Among predominantly low-income Black and Hispanic stroke survivors with uncontrolled hypertension, addition of NCM to HBPTM led to greater SBP reduction than HBPTM alone. Additional studies are needed to understand the long-term clinical outcomes, cost-effectiveness, and generalizability of NCM-enhanced telehealth programs among low-income Black and Hispanic stroke survivors with significant comorbidity.

RESUMO

This current pilot trial assessed the feasibility of implementing a point-of-use (PoU) micronutrient fortification in preschool settings. Preschool children (n = 151) aged 36-79 months were randomized into intervention (n = 76) and control (n = 75) groups, both receiving breakfast maize-porridge with added micronutrient or placebo powder for 52 school days. Process evaluation and early childhood development indicators were used to assess trial feasibility. Process evaluation results showed that the implementation components were feasible and could be delivered with high fidelity. The improvement in hemoglobin concentration in intervention and control groups were not significantly different (P = 0.250). There was medium likelihood for practical significance for the two global cognitive scores assessed: non-verbal index (intervention effects: 7.20; 95% confidence interval: 2.60, 11.81; P = 0.002, effect size: 0.55) and mental processing index (intervention effects: 2.73; 95% confidence interval: 0.25, 5.70; P = 0.072, effect size: 0.36) on the Kaufman Assessment Battery for Children, Second Edition. The lessons from this trial could help in planning/implementing future PoU micronutrient fortification trial among South African preschool children.

RESUMO

Biofortified maize varieties form an essential part of a nutritious diet; available evidence suggests that different processing methods may affect the final food products. The study aimed to evaluate the effects of processing (roasting) and harvesting time on the bioactive components (lutein, zeaxanthin, ß-cryptoxanthin, phytate, tannin and vitamin C) and colour properties (L*, a*, b*), of biofortified orange maize. The orange maize hybrids used for the study were obtained from the International Institute of Tropical Agriculture (IITA) diverse lines with high provitamin A (PVA) content. The results showed that harvesting time and roasting methods significantly (P ≤ 0.001) affected the colour properties. The positive values of ∆b* 30.7, 36.0 and 38.1 at 20 days after pollination (DAP), 27DAP and 34DAP, respectively showed that the intensity of orange colour increased with delay in harvesting time. In unprocessed freshly harvested orange hybrid maize; lutein, zeaxanthin, ß-cryptoxanthin, tannin and vitamin C increased with an increase in harvesting time. For roasted hybrid, the mean concentrations of all the bioactive components increased with increases in harvesting time except for tannin and vitamin C that showed a decrease at 20DAP and 27DAP. The results revealed that processing and time of harvest affect the levels of non-provitamin A carotenoids, tannins, phytic acid, Vitamin C and the colour properties of biofortified maize genotypes.

RESUMO

OBJECTIVE: To examine the prevalence and correlates of depression in a cohort of black and Hispanic stroke survivors with uncontrolled hypertension. SETTING: Baseline survey data from 10 stroke centres across New York City. PARTICIPANTS: Black and Hispanic stroke survivors with uncontrolled hypertension (n=450). OUTCOME MEASURES: Depressive symptoms were assessed with the 8-item Patient Reported Outcomes Measurement Information System (PROMIS) measure. Depression was defined as a PROMIS score ≥55. Other data collected included clinical factors, health-related quality of life (EuroQoL five dimensions (EQ-5D)), functional independence (Barthel Index, BI), stroke-related disability (Modified Rankin Score), physical function (PROMIS Physical Function) and executive functioning (Frontal Assessment Battery). RESULTS: The mean age was 61.7±11.1 years, 44% of participants were women and 51% were black. Poststroke depression was noted in 32% of the cohort. Examining bivariate relationships, patients with depression were observed to have poorer function and quality of life as evidenced by significantly lower PROMIS physical function scores (36.9±8.32 vs 43.4±10.19, p<0.001); BI scores (79.9±19.2 vs 88.1±15.1, p<0.001); EQ-5D scores (0.66±0.24 vs 0.83±0.17, p<0.001) and higher Rankin scores (2.10±1.00 vs 1.46±1.01, p<0.001) compared with those without depression. Multivariate (model adjusted) significant correlates of depression included lower self-reported quality of life (OR=0.02 (CI 0.004 to 0.12) being younger (OR=0.94; 95% CI 0.91 to 0.97); not married (OR=0.46; CI 0.24 to 0.89)); and foreign-born (OR=3.34, 95% CI 1.4 to 7.97). There was a trend for higher comorbidity to be uniquely associated with depression (≥3 comorbid conditions, OR=1.49, 95% CI 1.00 to 2.23). CONCLUSIONS: Poststroke depression is common among black and Hispanic stroke survivors with higher rates noted among foreign-born patients and those with high comorbidity. These findings highlight the importance of screening for depression in minority stroke survivors. TRIAL REGISTRATION NUMBER: http://www.clinicaltrials.gov. Unique identifier: NCT01070056.

RESUMO

Reviews of programmes in Bangladesh, Benin, the Philippines, Sri Lanka, Uganda, and Uzbekistan sought to identify health policy and programmatic factors that influenced breastfeeding practices during a 10 to 15 year period. Exclusive breastfeeding rates and trends were analysed in six countries in general and from an equity perspective in two of them. Success factors and challenges were identified in countries with improved and stagnated rates respectively. The disaggregated data analysis showed that progress may be unequal in population subgroups, but if appropriately designed and implemented, a programme can become a "health equalizer" and eliminate discrepancies among different subgroups. Success requires commitment, supportive policies, and comprehensiveness of programmes for breastfeeding promotion, protection and support. Community-based promotion and support was identified as a particularly important component. Although health workers' training on infant feeding support and counselling was prioritized, further improvement of interpersonal counselling and problem solving skills is needed. More attention is advised for pre-service education, including a stronger focus on clinical practice, to ensure knowledge and skills among all health workers. Large-scale communication activities played a significant role, but essential steps were often underemphasized, including identifying social norms and influencing factors, ensuring community participation, and testing of approaches and messages.
