Risk profiles, access to care, and outcomes in Hispanics hospitalized for lower extremity peripheral artery disease.

OBJECTIVE: Previous studies have shown that Hispanics have worse clinical outcomes for lower extremity peripheral artery disease (PAD) than non-Hispanic White (NHWs). Using a national database, this study aimed to document the contemporary burden of PAD in Hispanics by evaluating their risk profiles, access to care, and outcomes compared with NHWs. METHODS: Hospitalizations of Hispanics and NHWs with a primary diagnosis of PAD were identified using 2011-2017 National Inpatient Sample data. Patient sociodemographic characteristics, comorbidities, whether the admission was through the emergency department (ED) or elective, length of stay, and costs accrued were compared by ethnicity. Temporal trends in revascularizations, amputations, and ED admissions by year were evaluated with the Cochran-Mantel-Haenszel test and stratified by ethnicity. Data were combined across years and multivariable logistic regression was used to evaluate the association of ethnicity with inpatient revascularization, amputation, and mortality, adjusting for sociodemographic and cardiovascular risk factors. RESULTS: From 2011 to 2017, there were a total of 1,018,220 PAD hospitalizations among Hispanics (13.9%) and NHWs (86.1%) between 2011 and 2017. Hispanics were more often low income and uninsured and presented with higher burden of comorbidities including diabetes, renal failure, prior amputations, and chronic limb-threatening ischemia compared with NHWs. Most Hispanics were admitted via the ED compared with NHWs (58.0% vs 36.7%; d = 0.48), and median length of stay was almost a day longer (4.5 days vs 3.7 days). Hispanic ethnicity was associated with lower odds of surgical (odds ratio [OR], 0.62; 95% confidence interval [CI], 0.57-0.67) and endovascular revascularization (OR, 0.94; 95% CI, 0.89-0.996) and mortality (OR, 0.83; 95% CI, 0.75-0.93), but higher odds of minor (OR, 1.25; 95% CI, 1.20-1.31) and major (OR, 1.08; 95% CI, 1.03-1.14) amputation. CONCLUSIONS: Two tiers of health care consumption for inpatient PAD care and outcomes manifested among Hispanics and NHWs. First, Hispanics with PAD had a more vulnerable socioeconomic profile and presented with more severe PAD than NHWs. Second, they sought care more disproportionately through the ED and underwent more amputations than NHWs. To eradicate these inequities in PAD care and risk, strategies that improve access to outpatient care and expand health care coverage, as well as targeted management of risk factors in these vulnerable minority groups are needed.

Anti-Diabetic Activity of Glycyrrhetinic Acid Derivatives FC-114 and FC-122: Scale-Up, In Silico, In Vitro, and In Vivo Studies.

Type 2 diabetes (T2D) is one of the most common diseases and the 8th leading cause of death worldwide. Individuals with T2D are at risk for several health complications that reduce their life expectancy and quality of life. Although several drugs for treating T2D are currently available, many of them have reported side effects ranging from mild to severe. In this work, we present the synthesis in a gram-scale as well as the in silico and in vitro activity of two semisynthetic glycyrrhetinic acid (GA) derivatives (namely FC-114 and FC-122) against Protein Tyrosine Phosphatase 1B (PTP1B) and α-glucosidase enzymes. Furthermore, the in vitro cytotoxicity assay on Human Foreskin fibroblast and the in vivo acute oral toxicity was also conducted. The anti-diabetic activity was determined in streptozotocin-induced diabetic rats after oral administration with FC-114 or FC-122. Results showed that both GA derivatives have potent PTP1B inhibitory activity being FC-122, a dual PTP1B/α-glucosidase inhibitor that could increase insulin sensitivity and reduce intestinal glucose absorption. Molecular docking, molecular dynamics, and enzymatic kinetics studies revealed the inhibition mechanism of FC-122 against α-glucosidase. Both GA derivatives were safe and showed better anti-diabetic activity in vivo than the reference drug acarbose. Moreover, FC-114 improves insulin levels while decreasing LDL and total cholesterol levels without decreasing HDL cholesterol.

'[The pediatrician] said that maybe my milk, instead of doing good, no longer helped': the ecology of infant formula in rural communities in Central Mexico.

OBJECTIVE: As Mexico continues to develop, an epidemiological and nutritional transition has led to an increase in infant formula use in its rural and indigenous communities. Our objective was to determine the social and cultural factors that influence the use of formula in such populations in Central Mexico. DESIGN: Qualitative study using a data collection instrument based on the socio-ecological framework. SETTING: Two rural and indigenous communities in Central Mexico. PARTICIPANTS: Mothers, fathers, grandparents and healthcare providers. RESULTS: Breast-feeding was favoured in both communities; however, several cultural traditions hindered exclusive breast-feeding. As these communities became more developed, emerging ideas of modernity led to negative connotations about breast-feeding and many mothers began to view formula as a complement for breast-feeding. Formula was seen as a convenient solution for breast pain, insufficient milk and body image. Healthcare providers promoted the use of formula through their own beliefs, information, communication and conflicts of interest with formula industry representatives. The recent social and economic changes in these communities combined with the increased advertising and availability of breast milk substitutes have facilitated the preference for formula. CONCLUSIONS: Women in rural, indigenous communities in Central Mexico are increasingly using formula. Efforts at the policy and institutional levels are needed to protect mothers and their children from the detrimental consequences of unregulated formula promotion and the formula culture that it brings with it.

Reproductive health education program for Mexican women.

Objective: Improve knowledge, attitudes and reproductive behaviours through an educational intervention aimed at reproductive health in two groups of Mexican women. Materials and methods: We carried out an education program targeting two segments, indigenous women and marginalised adolescents, with a pre-test, immediate post-test and post-test six months after it was carried out. Instruments used: a reproductive health history was established (pre-test and post-test six months) and a questionnaire of knowledge, attitude and conduct related to reproductive health and condom use (pre-test, immediate post-test and post-test six months). Results: Improved test scores in reproductive health and condom use - knowledge, attitude and conduct, were notable in the group of indigenous women (p < .05). However, in the group of adolescents there was a significant increase (p < .05) only in reproductive health - knowledge and attitude; in condom usage, increase was only noted in knowledge and conduct, not in attitude (pre-test vs immediate post-test). Six months after post-test results there was a decrease in test scores in comparison with the immediate post-test results. They were however, higher than the pre-test scores. Conclusions: Both groups significantly increased short-term knowledge, attitude and conduct related to reproductive health and condom use through the implementation of an education program. Results show that this education program can contribute to the development of an effective education program.

Examining Outcomes in Patients Admitted With Comorbid Peripheral Artery Disease and Microvascular Disease.

BACKGROUND: Peripheral artery disease (PAD) and microvascular disease (MVD) are highly prevalent conditions that share common risk factors. This observational study aimed to characterize patients with both conditions and determine the impact of comorbid PAD/MVD on outcomes. METHODS AND RESULTS: Patients admitted across 31 states January 2011 through December 2018 with a primary or secondary diagnosis of PAD or MVD were included from the National Readmissions Database and weighted to approximate a national sample. Those age <18 years or with nonatherosclerotic leg injuries were excluded. Patients were divided into 3 groups: PAD-only, MVD-only, or comorbid PAD/MVD. Multiple logistic regression was used to evaluate associations with major and minor amputations, major adverse cardiac events, and in-hospital mortality. Cox regression was used to evaluate associations with readmission within 1 year. The PAD group was used as reference. The final cohort included 33 972 772 admissions: 9.1 million with PAD, 21.3 million with MVD, and 3.6 million with both. Annual admissions for PAD/MVD increased to >500 000 in 2018. Major and minor amputations increased ≈50% for PAD/MVD between 2011 and 2018. Compared with PAD-only, PAD/MVD was associated with a higher risk for major amputation (odds ratio [OR], 1.30 [95% CI, 1.28-1.32]), minor amputation (OR, 2.15 [95% CI, 2.12-2.18]), major adverse cardiac events (OR, 1.04 [95% CI, 1.03-1.04]), in-hospital mortality (OR, 1.07 [95% CI, 1.05-1.09]), and readmission (hazard ratio, 1.02 [95% CI, 1.02-1.02]) after adjustment for baseline factors. CONCLUSIONS: Comorbid MVD is present in a large and growing number of patients with PAD and is associated with augmented risk for adverse outcomes. Further prospective research is merited to understand this vulnerable population.

Sex Disparities in the Management, Outcomes, and Transfer of Patients Hospitalized for Cardiogenic Shock.

Background: Previous studies have shown that women have worse outcomes for cardiogenic shock (CS) than men. Patients who receive care in CS "hubs" have also been shown to have improved outcomes when compared to those treated at "spokes." This study aimed to examine the presence of sex disparities in the outcomes of CS in relation to hospital type. Methods: Hospitalizations of adults with a diagnosis of CS were identified using data from the 2016-2019 Nationwide Readmissions Database. CS "hubs" were defined as any centers receiving at least 1 interhospital transfer with CS, while those without such transfers were classified as "spokes." Data were combined across years and multivariable logistic regression modeling was used to evaluate the association of sex with in-hospital mortality, invasive procedures, and transfer to hubs. Results: There were a total of 618,411 CS hospitalizations (62.2% men) with CS related to acute myocardial infarction comprising 15.3 to 17.3% of women hospitalizations and 17.8 to 20.3% of men hospitalizations. In-hospital mortality was lower at hubs (34.5% for direct admissions, 31.6% for transfers) than at spokes (40.3%, all P < .01). Women underwent fewer invasive procedures (right heart catheterization, percutaneous coronary intervention, mechanical circulatory support) and had higher mortality than men. Female sex was independently associated with decreased transfers to hubs (odds ratio, 0.93; 95% CI, 0.89-0.96) and increased mortality (odds ratio, 1.09; 95% CI, 1.05-1.12). Conclusions: Women with CS were less likely to be treated at a hub or transferred to a hub, had higher in-hospital mortality, and had a lower likelihood of receiving CS-related procedures than men. Further research is needed to understand sex-specific gaps in CS outcomes.

Photovoice Lessons from a Peruvian Program in Combatting Stigma for Caregivers of Children with Disabilities.

BACKGROUND: Access to resources for children with disabilities and their caregivers are lacking worldwide, especially for low-and middle-income countries, especially those of Latin origin. Furthermore, decreased social visibility coupled with minimal support available for caregivers can negatively affect their overall mental well-being. Limited community-based participatory research has been done to understand the experiences of caregivers and identify effective measures of support. OBJECTIVES: To explore the impact of childhood disabilities on caregiver well-being and to assess how interactions between caregivers and their community affect their mental well-being. METHODS: This study used photovoice and community-based participatory research methodology. We recruited participants who had children enrolled in a rehabilitative program called Rehabilitation with Hope, located in Huancayo, Peru. Participants were given three photo assignments concerning their experiences as caregivers and they presented their photos at photo discussions after each assignment. We used thematic analysis to identify the main themes that arose from the discussions. RESULTS: Four main themes were identified: stigma, social support, self-esteem, and effects of photovoice. Caregivers often felt stigmatized by the community due to their child's disability. However, they found a stronger sense of social support and overall improved sense of self-esteem through the program and participation in photovoice. CONCLUSIONS: The results of this study suggest the effects of stigma on caregivers may be mitigated through enhanced social support and self-esteem. Additionally, photovoice is an effective tool to combat community stigma by allowing caregivers to share their narratives.

Discrepancies in infant feeding recommendations between grandmothers and healthcare providers in rural Mexico.

BACKGROUND: Infant feeding practices are rapidly changing within rural areas in Mexico, including indigenous communities. The aim of this study was to compare infant feeding recommendations between grandmothers and healthcare providers, to better understand the factors that may influence these practices within these communities. This study builds on research that recognizes the legacy of colonization as an ongoing process that impacts the lives of people through many pathways, including the substandard healthcare systems available to them. METHODS: Qualitative study based on secondary data analysis from interviews and focus groups guided by a socioecological framework conducted in 2018 in two rural, Indigenous communities in Central Mexico. Participants were purposively selected mothers (n = 25), grandmothers (n = 11), and healthcare providers (n = 24) who offered care to children up to two years of age and/or their mothers. Data were coded and thematically analyzed to contrast the different perspectives of infant feeding recommendations and practices between mother, grandmothers, and healthcare providers. RESULTS: Grandmothers and healthcare providers differed in their beliefs regarding appropriate timing to introduce non-milk foods and duration of breastfeeding. Compared to grandmothers, healthcare providers tended to believe that their recommendations were superior to those from people in the communities and expressed stereotypes reflected in negative attitudes towards mothers who did not follow their recommendations. Grandmothers often passed down advice from previous generations and their own experiences with infant feeding but were also open to learning from healthcare providers through government programs and sharing their knowledge with their daughters and other women. Given the contradictory recommendations from grandmothers and healthcare providers, mothers often were unsure which advice to follow. CONCLUSIONS: There are important differences between grandmothers and healthcare providers regarding infant feeding recommendations. Healthcare providers may perceive their recommendations as superior given the neocolonial structures of the medical system. Public health policies are needed to address the different recommendations mothers receive from different sources, by harmonizing them and following an evidence-informed approach. Breastfeeding programs need to value and to seek the participation of grandmothers.

Telehealth care before and during COVID-19: trends and quality in a large health system.

Objective: COVID-19 accelerated telehealth use to ensure care delivery, but there is limited data on the patient perspective. This study aimed to examine telehealth visit uptake before and during COVID-19 and correlates of patient satisfaction and interest in future telehealth visits. Materials and Methods: This was a cross-sectional observational study between October 2019 and April 2020. Participants included patients who completed satisfaction surveys following telehealth visits. Results: A total of 8930 patients completed the satisfaction survey using 4-point Likert Scales. Multivariable, hierarchical, cumulative logit models were constructed to examine correlates of satisfaction with quality of care and interest in future telehealth visits. Most patients were satisfied with the patient portal, video quality, and instructions (92.7%-96.8%). Almost half reported saving 1-2 h (46.9%). Correlates positively associated with quality of care and interest in future telehealth visits were ease of patient portal (odds ratio [OR], 1.43, 95% confidence interval [CI], 1.30-1.58; OR, 1.56, 95% CI, 1.41-1.73, respectively), video quality (OR, 1.62, 95% CI, 1.50-1.75; OR, 1.26, 95% CI, 1.16-1.37, respectively), instructions (OR, 5.62, 95% CI, 5.05-6.26; OR, 1.80, 95% CI, 1.62-2.01, respectively), and time saved (>4 h: OR, 1.69, 95%,CI, 1.22-2.34; OR, 3.49, 95% CI, 2.47-4.93, respectively). Being seen after the COVID-19 surge in telehealth (OR, 0.76, 95% CI, 0.63-0.93) or by providers with higher visit volume (OR, 0.71, 95% CI, 0.60-0.85) was associated with lower interest in future telehealth visits. Conclusions: Patients expressed relatively high satisfaction levels with telehealth. Better technical quality, quality of instructions, and greater time saved were associated with higher satisfaction ratings. To maintain interest in future telehealth use and improve the patient experience, we must enhance the quality of telehealth delivery platforms and instructions provided to patients.
