Epidemiology of Hypertension and Diabetes Mellitus in Latin America

Parameters for delivering ethnically and gender-sensitive primary care in cardiovascular health through telehealth. Systematic review

OBJECTIVE

To determine the parameters for providing primary care in cardiovascular health, with an ethnic and gender focus through telemedicine.

STUDY DESIGN

Systematic Literature Review.

METHODS

A systematic review was conducted using databases including PUBMED, Cochrane Library, CINAHL, EMBASE VHL, and other relevant sources. We included articles published in the last 15 years on parameters of telemedicine care with a differential approach focusing on ethnicity and gender. Screening, full-text reading, and information extraction were performed in duplicate and independently, though methodological quality assessment was not conducted.

RESULTS

Twenty-eight studies were included, with 46.43% originating from Australia and 50.00% employing a qualitative approach. Thirty-five point seventy-one percent provided operational recommendations, and 32.14% related to the ethnic approach. Seven operational categories were identified: holistic approach to health, flexible approach to health, accessible health services, continuous improvement in service quality, culturally appropriate and qualified workforce, self-determination and empowerment, and community participation. Additionally, five categories were identified pertaining to the ethnic approach: public policy in favor of ancestral knowledge in primary health care, training of community agents and health personnel from an intercultural perspective, complementarity between traditional and western health practices, and the recognition of telehealth's value in intercultural approaches.

CONCLUSIONS

There is a need to adjust operational aspects related to the implementation of indigenous public policy, and to increase the number of qualified community human resources to provide holistic, comprehensive, and culturally appropriate care. Regarding gender, there is a necessity to implement public policy based on health determinants that will dismantle barriers to accessing gender-specific services and comprehensively assess cardiovascular risk.

Predictors of cognitive change in cognitively healthy older women in Panama: the PARI-HD study

Background

Evidence suggests that a combination of biological and social factors influence risk of dementia differently for women and men. In healthy older women, several factors may contribute to changes in cognition.

Objective

Describe the characteristics associated with variation in cognition in a sample of cognitively healthy older Panamanian women.

Methods

The study includes cross-sectional analyses of cognitive domains at baseline (n = 357) and 17-month (SD = 2.0) follow-up (n = 200) for women aged 60 years and older enrolled in the Panama Aging Research Initiative-Health Disparities (PARI-HD) study. Instruments included clinical questionnaires, physiological measures, and a neuropsychological test battery assessing global cognition and seven cognitive domains. Multiple regression analyses examined the associations between demographic and clinical characteristics and cognition at baseline. Repeated measures analyses were used to investigate changes in cognition from baseline to follow-up.

Results

On average, participants were 68.6 years of age (SD = 5.9) with 16.1 years of education (SD = 4.7). Age, income, and education showed robust associations with baseline cognition. Subjective cognitive impairment was associated with lower performance in global cognition, verbal learning, and memory domains. Only performance in the attention domain decreased at follow-up, and subjective health state and depressive symptoms significantly predicted the change in attention.

Discussion

Our study findings contribute to the investigation of cognitive health in older Hispanic women and to the understanding of sociodemographic and health-related factors associated with cognitive decline and the progression to cognitive impairment and dementia.

Chronic Comorbidities in Middle Aged Patients Contribute to Ineffective Emergency Hematopoiesis in Covid-19 Fatal Outcomes

BACKGROUND AND AIMS

Mexico is among the countries with the highest estimated excess mortality rates due to the COVID-19 pandemic, with more than half of reported deaths occurring in adults younger than 65 years old. Although this behavior is presumably influenced by the young demographics and the high prevalence of metabolic diseases, the underlying mechanisms have not been determined.

METHODS

The age-stratified case fatality rate (CFR) was estimated in a prospective cohort with 245 hospitalized COVID-19 cases, followed through time, for the period October 2020-September 2021. Cellular and inflammatory parameters were exhaustively investigated in blood samples by laboratory test, multiparametric flow cytometry and multiplex immunoassays.

RESULTS

The CFR was 35.51%, with 55.2% of deaths recorded in middle-aged adults. On admission, hematological cell differentiation, physiological stress and inflammation parameters, showed distinctive profiles of potential prognostic value in patients under 65 at 7 days follow-up. Pre-existing metabolic conditions were identified as risk factors of poor outcomes. Chronic kidney disease (CKD), as single comorbidity or in combination with diabetes, had the highest risk for COVID-19 fatality. Of note, fatal outcomes in middle-aged patients were marked from admission by an inflammatory landscape and emergency myeloid hematopoiesis at the expense of functional lymphoid innate cells for antiviral immunosurveillance, including NK and dendritic cell subsets.

CONCLUSIONS

Comorbidities increased the development of imbalanced myeloid phenotype, rendering middle-aged individuals unable to effectively control SARS-CoV-2. A predictive signature of high-risk outcomes at day 7 of disease evolution as a tool for their early stratification in vulnerable populations is proposed.

Randomized Controlled Trial of Home Telemonitoring of Blood Pressure with an Adapted Tensiometer with SMS Capability

Despite being a public health problem, less than a third of hypertensive patients manage to control blood pressure (BP). In this paper, we conducted a two-arm randomized controlled trial to investigate the efficacy of an SMS-based home BP telemonitoring system compared to usual care in patients with uncontrolled hypertension from a primary care center. This study was conducted between April and August 2018. Participants in the intervention arm used a custom-designed telemonitoring device for two weeks and were followed up for two additional weeks; controls were followed for 4 weeks. The main objective of this study is to evaluate the impact on blood pressure of a telemonitoring system using a blood pressure monitor adapted to send data via SMS to health providers in primary care centers for 4 weeks. In this trial, 38 patients were included in the analysis (18 in each arm), 68% were women, and the mean age was 68.1 [SD: 10.8 years], with no differences between arms. Among the results we found was that There was no significant difference in the change in systolic BP values between the control and intervention arm (-7.2 [14.9] mmHg vs. -16.3 [16.7] mmHg; p = 0.09). However, we found a significant difference in the change of diastolic BP (-1.2 [6.4] mmHg vs. -7.2 [9.8] mmHg; for the control and intervention arms, respectively p = 0.03). With all this, we conclude that an SMS-based home BP telemonitoring system is effective in reducing diastolic BP by working in conjunction with primary care centers. Our findings represent one of the first interventions of this type in our environment, being an important alternative for the control of high blood pressure.

Prevalence of food addiction determined by the Yale Food Addiction Scale in Latin America: A systematic review with meta-analysis

OBJECTIVE

Food addiction (FA) has been extensively investigated worldwide; however, the prevalence of FA in the Latin American population has yet to be established and past work has largely neglected the specificities of this region, that includes the most significant economic disparities in the world. Thus, the objective of this study was to assess the prevalence of FA measured by the Yale Food Addiction Scale in Latin America.

METHOD

The search was performed on MEDLINE, ScienceDirect, LILACS, IBECS, SciELO, PsycArticles, CENTRAL, and the gray literature. FA prevalence data were collected, and random effects meta-analyses were performed to calculate the overall weighted prevalence, the prevalence by country, and by clinical and non-clinical samples.

RESULTS

A total of 10,082 occurrences were identified through database searches, and 23 studies were included (Mexico = 9; Brazil = 7; Chile = 4; Argentina = 1; Peru = 1; Uruguay = 1). The prevalence of FA found in clinical samples was 38% (95% CI: 16%-63%; I²  = 98.67%; 8 studies), while in non-clinical samples, it was 15% (95% CI: 10%-21%; I²  = 98.51%; 15 studies).

DISCUSSION

The average prevalence of FA in the Latin American countries included here was in accordance with that reported in other regions worldwide. It is noteworthy that the studies were conducted only in six countries, which are among those with the highest income in the region and do not represent the situation in native populations or those with lower purchasing power. This gap in the data also reflects the effects of economic disparities on the availability of empirical data in the region.

PUBLIC SIGNIFICANCE

The prevalence of food addiction in Latin America was similar to that reported in other regions. It was higher among individuals with overweight, whether or not undergoing bariatric surgery, than in non-clinical samples. These findings contribute to aggregate information about this condition that has drawn the attention of clinicians and researchers.

May Measurement Month 2019: an analysis of blood pressure screening results from Colombia

Hypertension awareness and control is poor in low- and middle-income countries. Thus, implementing strategies to increase hypertension detection is needed. Colombia participated as one of the 92 countries involved in the third campaign of the May Measurement Month in 2019. Blood pressure (BP) was measured in 48 324 volunteers from 13 departments in Colombia. In total, 27.9% individuals were identified with hypertension. Of those with hypertension, 63.7% were aware of their condition, 60.0% were on antihypertensive medication, and 38.4% had controlled BP. These results showed low levels of awareness, treatment, and control of hypertension in this sample of subjects volunteered to participate, suggest the urgent necessity of implementing programmes to improve the diagnosis and management of hypertension in Colombia.
