Sex-specific relationships of inflammatory biomarkers with blood pressure in older adults.

Emerging evidence indicates an association between blood pressure and inflammation, yet this relationship remains unclear in older adults, despite the elevated prevalence of hypertension. We investigated the association between blood pressure, high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and white blood cell (WBC) count in a cohort of 3571 older adults aged 65 and above, and 587 middle-aged participants (55-59 years old). In women aged 65 and above, the relationship between inflammatory markers and blood pressure was consistent, with hs-CRP and WBC emerging as predictors of high blood pressure.

Angiotensin-converting enzyme inhibitors and angiotensin-II-receptor antagonists modulate sodium handling based on endogenous lithium clearance.

Background: Numerous studies based on assessment of lithium clearance demonstrated higher sodium reabsorption in renal proximal tubules in individuals with hypertension, overweight, obesity, metabolic syndrome, or diabetes.

Aims: We aimed to assess the influence of angiotensin-converting enzyme inhibitors (ACE-I) or angiotensin-II-receptor antagonists (ARB) treatment on sodium handling.

Methods: In a sample of 351Caucasian subjects without diuretic treatment with prevailing sodium consumption, we studied associations between renal sodium reabsorption in proximal (FPRNa) and distal (FDRNa) tubules assessed by endogenous lithium clearance and daily sodium intake measured by 24-hour excretion of sodium (UNaV), in the context of obesity and long-term treatment with ACE-I or ARB.

Neglect and self-rated health among older adults - a cross-sectional study in Poland.

The aim of this cross-sectional study is to examine if neglect is associated with self-rated health (SRH) and if neglect mediates the association between selected factors and self-rated health, among older men and women. The analyses were based on face-to-face computer-assisted personal interviews conducted with 1632 randomly selected community-dwelling individuals aged 65 years and more from among the general population of Lesser Poland. The regression models' analysis revealed that elder neglect was associated with self-rated health, and the mediation analysis demonstrated that neglect mediates the association between frequency of church attendance and SRH, as well as between marital status (being a widower vs being married) and SRH, among men.

Serial echocardiographic evaluation of COVID-19 patients without prior history of structural heart disease: a 1-year follow-up CRACoV-HHS study.

Background: It is a well-known fact that COVID-19 affects the cardiovascular system by exacerbating heart failure in patients with preexisting conditions. However, there is a poor insight into the cardiovascular involvement and sequelae in patients without preexisting conditions. The aim of the study is to analyse the influence of COVID-19 on cardiac performance in patients without prior history of structural heart disease.

Urocortin 2 - a protective effect in hypertension?

Urocortin 2, an endogenous selective ligand for the corticotropin-releasing hormone receptor type 2, has been suggested to exert cardioprotective effects. We analyzed the possible relationship between the level of Ucn2 and specific indicators of cardiovascular risk factors in patients with untreated hypertension and in healthy subjects. Sixty seven subjects were recruited: 38 with newly diagnosed treatment-naive hypertension (with no pharmacological treatment - HT group) and 29 healthy subjects without hypertension (nHT group).

Effectiveness and Safety of SARS-CoV-2 Vaccination in HIV-Infected Patients-Real-World Study.

Clinical data included: age, sex, admission parameters: respiratory rate, oxygen saturation, CRP (C-reactive protein), IL6 (interleukin 6), IG - immature granulocytes, WBC (white blood count), neutrophil count, lymphocyte count, serum ferritin, LDH (lactate dehydrogenase), NIH (National Institute of Health) severity score; parameters of clinical course: in-hospital death, transfer to the ICU (intensive care unit), length of hospital stay.

Factors associated with mortality in hospitalised, non-severe, older COVID-19 patients - the role of sarcopenia and frailty assessment.

Background: COVID-19 has affected older persons the most. The propensity to have severe COVID-19 or die of the infection was especially prevalent among older subjects with multimorbidity, frailty and sarcopenia. The aim of our study was to check which of the simple clinical biomarkers, including the assessment of muscle and frailty, would associate with the survival and the length of hospital stay in older patients with COVID-19.

Chemerin as a Potential Marker of Resolution of Inflammation in COVID-19 Infection.

Chemerin is one of the specialized pro-resolving mediators that participate in the early phase of inflammation and contribute to the initiation of the pro-resolving response. There is a paucity of data regarding the time course of chemerin during acute infections. We aimed to evaluate the sequence of inflammatory responses in the acute COVID-19 phase throughout onset and resolution of inflammation.
