Hyperinflammation present in individuals with severe COVID-19 has been associated with an exacerbated cytokine production and hyperactivated immune cells. Endoplasmic reticulum stress leading to the ...unfolded protein response has been recently reported as an active player in inducing inflammatory responses. Once unfolded protein response is activated, GRP78, an endoplasmic reticulum-resident chaperone, is translocated to the cell surface (sGRP78), where it is considered a cell stress marker; however, its presence has not been evaluated in immune cells during disease. Here we assessed the presence of sGRP78 on different cell subsets in blood samples from severe or convalescent COVID-19 patients. The frequency of CD45+sGRP78+ cells was higher in patients with the disease compared to convalescent patients. The latter showed similar frequencies to healthy controls. In patients with COVID-19, the lymphoid compartment showed the highest presence of sGRP78+ cells versus the myeloid compartment. CCL2, TNF-α, C-reactive protein, and international normalized ratio measurements showed a positive correlation with the frequency of CD45+sGRP78+ cells. Finally, gene expression microarray data showed that activated T and B cells increased the expression of GRP78, and peripheral blood mononuclear cells from healthy donors acquired sGRP78 upon activation with ionomycin and PMA. Thus, our data highlight the association of sGRP78 on immune cells in patients with severe COVID-19.
the aim of this study was to analyze the status of the management of vascular risk factors (hypertension and diabetes) at hospital level (3, 4 and 5) in Murang'a County (Kenya) health system.
between ...July and December 2018 we performed a joint intervention about the strategies for improving care management of hypertension and diabetic patients in Murang'a (Kenya). A survey based on the recommendations from WHO about management of diabetes and hypertension was completed for 9 health-care centers. The survey made use of a semi-structured questionnaire, while the units of analysis for the survey were households.
the number of patients recorded at medical registers with diabetes and hypertension registered in public hospitals in Murang'a County were 6628 (0.45%) and y 6694 (0.45%), respectively. In the surveyed health-care centers, no hospital use electrogram and only one had troponin test. No hospital stocked Isosorbide dinitrate and Glicerine trinitate to prevent chest pain in patients with a heart condition. Only 3 of the clinics performed visual acuity examination and no facility did neurologic examination for neuropathy complications. No public hospital had HbA1 and did microalbuminuria test available.
it is necessary to improve to establish screening methods, diagnosis, treatment and follow-up of patients with hypertension and diabetes in Murang'a County at the various levels of health care.
Abstract only Background: Mounting evidence points to a connection between cardiovascular risk during middle age and brain health later in life. The American Heart Association’s Life’s Essential 8 ...(LE8) constitute a research and public health construct capturing key determinants of cardiovascular health. We tested the hypothesis that worse LE8 profiles are associated with higher composite risk of the most important clinical endpoints related to brain health. Methods: We conducted a two-stage (discovery and replication) prospective study using data from the UK Biobank (UKB) and All of Us (AoU). We excluded participants with stroke, dementia, or late-life depression (LLD) at baseline. The exposure of interest was the LE8 score, a validated tool that captures the LE8 components (blood pressure, glucose, and cholesterol, body mass index, smoking, physical activity, diet, and sleep duration), organized in 3 categories. The outcome of interest was a composite of stroke, dementia, or LLD. We evaluated the associations of interest via multivariable Cox proportional hazard models. Results: The discovery stage included 334,505 UKB participants (mean age 56, 47% female), in whom the unadjusted risk of the composite outcome of interest was 471 (0.7%), 2,224 (1.1%) and 1,143 (1.7%) in participants with optimal, intermediate, and poor cardiovascular health (p<0.001). This association remained significant in multivariable Cox models (optimal versus poor cardiovascular health OR 2.14; 95% CI 1.92 - 2.39; p<0.001). The replication stage included 92,551 AoU participants (mean age 57, 59% female), in whom the unadjusted risk of the composite outcome was 547 (3%), 3,451 (6.2%) and 1,833 (10%) in participants with optimal, intermediate, and poor cardiovascular health (p<0.001). This association remained significant in multivariable Cox models (optimal versus poor cardiovascular health OR 2.20; 95% CI 1.99 - 2.42; p<0.001). Conclusions and Relevance: Among middle-aged UKB and AoU participants, poorer LE8 cardiovascular health profiles were strongly associated with a higher risk of developing a composite endpoint that captures the most important diseases related to brain health. These findings support the utilization of this endpoint in clinical trials focused on brain health.
