Background & Aims: Cardiometabolic traits are complex interrelated traits that result from a combination of genetic and lifestyle factors. This study aimed to assess the interaction between genetic variants and dietary macronutrient intake on cardiometabolic traits [body mass index, waist circumference, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, triacylglycerol, systolic blood pressure, diastolic blood pressure, fasting serum glucose, fasting serum insulin, and glycated haemoglobin].

Methods: This cross-sectional study consisted of 468 urban young adults aged 20 ± 1 years, and it was conducted as part of the Study of Obesity, Nutrition, Genes and Social factors (SONGS) project, a sub-study of the Young Lives study.

Article Synopsis
  • Scientists are still trying to understand the impact of COVID-19 clinical biomarkers, which are indicators of the disease's progression and severity.
  • A study in Lima and Huaraz (two Peruvian cities at different altitudes) compared COVID-19 patients in ICUs, those hospitalized but not in ICUs, and healthy controls, checking levels of five specific biomarkers.
  • Results showed higher levels of ferritin, C-reactive protein, and IL-6 in both patient groups at both locations, with unique findings for hepcidin and zinc, indicating that high-altitude patients have distinct biomarker profiles compared to those at lower altitudes.

has been described as a cause of serious community-acquired infections in tropical countries. Currently, its implications when simultaneously identified with other pathogens are not yet adequately understood. A descriptive study was conducted on hospitalized patients with a diagnosis of moderate/severe SARS-CoV-2-induced pneumonia confirmed via real-time RT-PCR.
