Extensive data covering 2086 examinees served for analysis of peripheral vascular, locomotion, neurologic disorders developing at various stages of adaptation process in workers engaged into mining in the North. Unfavorable general and local cooling resulted in overstrain of thermoregulation mechanisms, caused lower performance, difficulties in adequate occupational functioning, early formation of diseases. Association of cooling and intensive vibration with significant physical load induced neurovascular and neurodystrophic changes being a result of both local microcirculation disturbances and disordered regulation of peripheral vascular tone, higher excitability of vasoconstrictors stimulated by central mechanisms.

Restenosis remains a long-standing limitation to effectively maintain functional blood flow after percutaneous transluminal angioplasty (PTA). While the use of drug-coated balloons (DCBs) containing antiproliferative drugs has improved patient outcomes, limited tissue transfer and poor therapeutic targeting capabilities contribute to off-target cytotoxicity, precluding adequate endothelial repair. In this work, a DCB system was designed and tested to achieve defined arterial delivery of an antirestenosis therapeutic candidate, cadherin-2 (N-cadherin) mimetic peptides (NCad), shown to selectively inhibit smooth muscle cell migration and limit intimal thickening in early animal PTA models.

Objectives: This structured, targeted literature review aimed to assess the mortality, humanistic and economic burden of eight organ manifestations which are commonly experienced by systemic sclerosis patients.
Methods: Identification of relevant literature was carried out by searching in Ovid MEDLINE and EMBASE, PubMed, and NHS Economic Evaluation Database in August 2023. Studies reporting original data on patients with systemic sclerosis with at least one of eight organ manifestations (interstitial lung disease and/or pulmonary hypertension, skin, peripheral vascular, musculoskeletal, gastrointestinal, cardiac or renal involvement) published within the last 15 years were included.
Arterial compliance (AC) is an important cardiovascular parameter characterizing mechanical properties of arteries. AC is significantly influenced by arterial wall structure and vasomotion, and it markedly influences cardiac load. A new method, based on a two-element Windkessel model, has been recently proposed for estimating AC as the ratio of the time constant T of the diastolic blood pressure decay and peripheral vascular resistance derived from clinically available stroke volume measurements and selected peripheral blood pressure parameters which are less prone to peripheral distortions.

Introduction: Foot ulcers are one of the most serious complications of diabetes, leading to significant risks on amputation and mortality. Peripheral arterial disease (PAD) is an important factor for the development and the outcome of diabetic foot ulcers (DFU). Although prompt and accurate detection of PAD is critical to reduce complications, its diagnosis can be challenging with currently used bedside tests (such as ankle-brachial index and toe pressure) due to medial arterial calcification.
