Article Abstract
Wearable sensors have seen remarkable recent technological developments, and their role in healthcare is expected to expand. Specifically, monitoring tissue circulation in patients who have undergone reconstructive surgery is critical because blood flow deficiencies must be rescued within hours or the transplant will fail due to thrombosis/haematoma within the artery or vein. We design a wearable, wireless, continuous, multipoint sensor to monitor tissue circulation. The system measures pulse waves, skin colour, and tissue temperature to reproduce physician assessment. Data are analysed in real time for patient risk using an algorithm. This multicentre clinical trial involved 73 patients who underwent transplant surgery and had their tissue circulation monitored until postoperative day 7. Herein, we show that the overall agreement rate between physician and sensor findings is 99.2%. In addition, the patient questionnaire results indicate that the device is easy to wear. The sensor demonstrates non-invasive, real-time, continuous, multi-point, wireless, and reliable monitoring for postoperative care. This wearable system can improve the success rate of reconstructive surgeries.

Polyamines (PAs), including spermidine, spermine and their precursor, putrescine, are ubiquitous molecules that are vital for a variety of physiological processes. Recently, PAs gained research attention because of their roles in promoting longevity and preventing age-related diseases. Circulating and tissue levels of PAs appear to decline with age, while higher intake of PAs in humans is correlated with better health during aging.

Objective: Hirudotherapy (HT), the therapeutic use of medicinal leeches, has been practised for centuries, and the interest in modern medicine has recently been renewed. This study evaluates the clinical outcomes of HT at Herba Medical Center in Azerbaijan between 2020 and 2024, focusing on its efficacy across 11 medical conditions.
Methods: A total of 181 patients were treated using disposable medicinal leeches () sourced from hygienic farms approved by Azerbaijan's Ministry of Ecology and Natural Resources.

Prostate cancer is a significant global health issue with inflammation emerging as a critical driver of progression. The prostate tumor microenvironment (TME) is comprised of tumor cells, mesenchymal stem cells, immune cells, cancer-associated fibroblasts, adipocytes, and the extracellular matrix. All of these TME components interact soluble factors, such as growth factors, cytokines, and chemokines.

Objective: The key molecular events signifying the -induced gastric carcinogenesis process are largely unknown.
Methods: Bulk tissue-proteomics profiling were leveraged across multi-stage gastric lesions from Linqu ( = 166) and Beijing sets ( = 99) and single-cell transcriptomic profiling ( = 18) to decipher key molecular signatures of -related gastric lesion progression and gastric cancer (GC) development. The association of key proteins association with gastric lesion progression and GC development were prospectively studied building on follow-up of the Linqu set and UK Biobank ( = 48,529).
The potential value of cytokine, cortisol and vitamin D profiles in foals from birth to weaning for respiratory disease prediction on a farm endemic for Rhodococcus equi pneumonia.

Background: Rhodococcus equi causes pneumonia in young foals, but disease susceptibility and severity vary. Cortisol and vitamin D modulate immune responses and cytokine production during bacterial infection, and altered concentrations are associated with sepsis in neonatal foals. We hypothesised an age and disease effect on circulating steroid hormone concentrations in foals, and that differences in cytokines and steroid hormone concentrations would predict disease severity in pneumonic foals.
