Arterial hypertension is one of the most widespread diseases in the world, both in women and men. In Poland, about 45% of the adult population suffers from arterial hypertension--it afflicts 45% of men and 36-38% of women. Arterial hypertension is a set of regulatory disorders of a complicated, multifactor etiology encompassing genetic conditions, the influence of the environment and some individual factors. Being also psychosomatic disorder it is strongly linked with improper adaptation to stress, personality traits and behavioural conditions esspecially with the type A behaviour pattern. This type of behaviour includes a strong need of achievement a tendency to dominate, and aggressiveness. The type A women--impatient, aggressive, hostile to their environment, committed to work and competitive--have a higher CVR (cardiovascular reactivity) coefficient and higher arterial blood pressure than type B. Some authors suggest that the lowering of estrogen levels in women over the age of 50 increases the frequency of occurrence of arterial hypertension. In spite of the fact that we do not have a full knowledge of the mechanisms starting the reaction chain, the awareness of these factors can help us decrease the risk of the development of the disease or hinder its progression.

Keyhole decompression surgery for holospinal epidural abscess: a novel approach for spinal stability preservation.
Eur Spine J
January 2025
Department of Orthopaedic Surgery, Graduate School of Medicine, Chiba University, 1-8-1 Inohana, Chuo-ku, Chiba, 260-8670, Japan.
Purpose: Spinal epidural abscesses are rare yet serious conditions, often necessitating emergency surgical intervention. Holospinal epidural abscesses (HEA) extending from the cervical to the lumbosacral spine are even rarer and present significant challenges in management. This report aims to describe a case of HEA with both ventrally-located cervical and dorsally-located thoracolumbar epidural abscesses treated with a combination of anterior keyhole decompression and posterior skip decompression surgeries.

As several decades of research have shown the cardioprotective effects of angiotensin-converting enzyme (ACE) inhibitors alone or in combination with diuretics, we were interested in investigating the effects of subchronic therapy of these drugs on ischemia-reperfusion (I/R) damage to the heart, as well as their influence on oxidative status. The research was conducted on 40 spontaneously hypertensive male Wistar Kyoto rats, divided into 4 groups. Animals were treated for four weeks with 10 mg/kg/day zofenopril alone or in combination with hydrochlorothiazide, indapamide and spironolactone per os.

Background: Renal autoregulatory mechanisms modulate renal blood flow. Connecting tubule glomerular feedback (CNTGF) is a vasodilator mechanism in the connecting tubule (CNT), triggered paracrinally when high sodium levels are detected via the epithelial sodium channel (ENaC). The primary activation factor of CNTGF-whether NaCl concentration, independent luminal flow, or the combined total sodium delivery-is still unclear.

Background: The potential role of Klebsiella pneumoniae (K.pn) in hypertension development has been emphasized, although the specific mechanisms have not been well understood. Bacterial extracellular vesicles (BEVs) released by Gram-negative bacteria modulate host cell functions by delivering bacterial components to host cells.

Department NEUROFARBA, University of Florence; Paediatric and Liver Unit, Meyer Children's Hospital IRCCS, Florence, Italy.
Background: Elexacaftor-tezacaftor-ivacaftor (ETI) has significantly improved the clinical course of people with cystic fibrosis (pwCF) and eligible CFTR variants. In this study, we prospectively evaluated liver elastography, liver fibrosis indices and liver tests in children with CF aged 6-12 years started on ETI therapy.
Methods: Body mass index, sweat test, percent predicted forced expiratory volume in one second, serum markers of liver injury or portal hypertension, liver fibrosis indices, controlled attenuation parameter and liver stiffness were assessed before starting ETI and three and twelve months post-ETI, according to new international guidelines.
