ABSTRACT

BACKGROUND: South Asian individuals shoulder a disproportionate burden of cardiometabolic diseases. OBJECTIVES: The purpose of this study was to determine if vascular regenerative cell content varies significantly between South Asian and White European people. METHODS: Between January 2022 and January 2023, 60 South Asian and 60 White European adults with either documented cardiovascular disease or established diabetes with ≥1 other cardiovascular risk factor were prospectively enrolled. Vascular regenerative cell content in venous blood was enumerated using a flow cytometry assay that is based on high aldehyde dehydrogenase (ALDHhi) activity and cell surface marker phenotyping. The primary outcome was the difference in frequency of circulating ALDHhi progenitor cells, monocytes, and granulocytes between the 2 groups. RESULTS: Compared with White European participants, those of South Asian ethnicity were younger (69 ± 10 years vs 66 ± 9 years; P < 0.05), had lower weight (88 ± 19 kg vs 75 ± 13 kg; P < 0.001), and exhibited a greater prevalence of type 2 diabetes (62% vs 92%). South Asian individuals had markedly lower circulating frequencies of pro-angiogenic ALDHhiSSClowCD133+ progenitor cells (P < 0.001) and ALDHhiSSCmidCD14+CD163+ monocytes with vessel-reparative capacity (P < 0.001), as well as proportionally more ALDHhi progenitor cells with high reactive oxygen species content (P < 0.05). After correction for sex, age, body mass index, and glycated hemoglobin, South Asian ethnicity was independently associated with lower ALDHhiSSClowCD133+ cell count. CONCLUSIONS: South Asian people with cardiometabolic disease had less vascular regenerative and reparative cells suggesting compromised vessel repair capabilities that may contribute to the excess vascular risk in this population.

ABSTRACT

BACKGROUND: South Asians (SAs) represent ∼25% of the world's population and account for >50% of global cardiovascular (CV) deaths, yet they continue to be underrepresented in contemporary clinical trials. The REDUCE-IT study demonstrated in a high-risk and predominantly White population that icosapent ethyl (IPE) lowered major adverse cardiovascular events by 25%. We sought to determine the generalizability of these results to a high-risk population of SAs with established CV disease living in Canada. METHODS: This was a cross-sectional observational study of 200 statin-treated SAs (≥45 years) with atherosclerotic CV disease (ASCVD) (NCT05271591). SA ethnicity was self-identified as being of Anglo-Indian, Bangladeshi, Bengali, Bhutanese, Goan, Gujarati, Indian, Jatt, Kashmiri, Maharashtrian, Malayali, Nepali, Pakistani, Punjabi, Sindhi, Sinhalese, Sri Lankan, Tamil, Telugu, or other SA. ASCVD was defined as the presence of coronary, carotid, or peripheral atherosclerosis. FINDINGS: Mean age of the cohort was 67 years, where 82% were men and 57% had diabetes. The predominant ASCVD phenotype was coronary artery disease (94%). Mean (SD) baseline LDL-C and triglycerides were 1.70 (0.8) mmol/L and 1.42 (1.0) mmol/L, respectively. Three-quarters were on high-intensity statin therapy. According to the Health Canada/Canadian Cardiovascular Society Guidelines and FDA-approved indication, 33% and 25% of the participants were, respectively, eligible for IPE. CONCLUSIONS: A large proportion of high-intensity, statin-treated, high-risk patients with ASCVD and of self-reported SA ethnicity are eligible for IPE. These data have important translational implications for SAs who are at a disproportionately higher risk of CV morbidity and mortality. FUNDING: This study was funded by an unrestricted grant provided by HLS Therapeutics Inc, Canada.

ABSTRACT

INTRODUCTION: The clinical benefit of curcumin, the active ingredient in turmeric, among women diagnosed with polycystic ovarian syndrome (PCOS) is unclear. In this systematic review, we aim to provide a brief review of the existing literature on the association between curcumin supplementation and PCOS. EVIDENCE ACQUISITION: Published articles relevant to the topic was obtained through extensive search using relevant keywords such as "polycystic ovarian syndrome," "PCOS," "turmeric," and "curcumin." Inclusion criteria included studies that investigated PCOS and turmeric/curcumin, while studies that investigated the use of curcumin in other gynecological disorders, infertility, rodent studies, and non-RCTs were excluded. EVIDENCE SYNTHESIS: A total of 14 articles were found and only five studies were incorporated based on the exclusion criteria. The main findings were that curcumin supplementation aids in improvement of lipid and glycemic profiles, Body Mass Index (BMI) and lowers androgen levels associated with PCOS. CONCLUSIONS: We shed light on additional therapeutic management for PCOS other than the conventional treatment. Further studies are required with larger sample sizes and diverse patient population to derive definitive conclusions regarding benefits of curcumin supplementation in PCOS.

ABSTRACT

BACKGROUND: Vaccine hesitancy presents a major challenge during the COVID-19 pandemic. It is crucial to address the factors contributing to vaccine hesitancy necessary to control the associated morbidity and mortality. This study aimed to investigate the impact of professional medical guidance on the likelihood of receiving the COVID-19 vaccine in immigrants of USA and Canada. MATERIALS AND METHODS: A total of 92 immigrants in the USA and Canada who predominantly spoke Malayalam were recruited using social media platforms. An online survey was administered investigating participants' confidence in receiving the COVID-19 vaccine. Following, a short webinar was conducted by a medical professional explaining the efficacy and safety of the vaccine. A postwebinar survey was immediately given assessing the confidence and likelihood of receiving the vaccine. SPSS was used to generate descriptive statistics and Pearson Chi-square analysis where appropriate. RESULTS: Results revealed that participants who attended the webinar reported greater confidence in receiving the COVID-19 vaccine. There was a statistically significant difference between pre- and postwebinar confidence scores for the COVID-19 vaccine, χ2 (12, n = 80) = 43.34, P < 0.01. CONCLUSION: Results from the current study demonstrate the successful delivery of professional medical guidance to the general public through online small-group sessions to help address the misconceptions surrounding the COVID-19 vaccine and combat vaccine hesitancy among vulnerable populations. Future studies should focus on interventions addressing vaccine hesitancy in larger and diverse populations and analyze other barriers to vaccination.
