During strenuous exercise, skin temperature (Tsk) plays an essential role in thermoregulatory processes. As indicated in the literature, its response might be influenced by body composition, among other factors. Hence, the objectives of this investigation were to determine whether there is a correlation between selected body components, specifically fat tissue and muscle tissue, and Tsk during graded exercise and recovery in athletes, and to identify which body component exhibits the strongest correlation with Tsk. Participants were grouped according to their aerobic capacity (VOmax/kg). A significant main effect was observed for the test stages (p < .001, η = 0.71), with Tsk decreasing from the start of the exercise, significantly decreasing at 12 km/h (p < .001), and then increasing after exercise, especially within the first 5 min of recovery. Weak and non-significant effect for group/stage interaction was detected (p = .374, η = 0.03). A significant negative correlation was found between Tsk and both total tissue fat [%] (-0.51 < r < -0.63, p < .001) and lower limb tissue fat [%] (-0.50 < r < -0.71, p < .001) across all test stages. The correlation between Tsk and BMI was inconsistent, appearing only during the first stage of exercise and throughout recovery. No correlation was observed between Tsk and skeletal muscle mass, appendicular lean soft tissue, or relative skeletal muscle index. Endurance running to exhaustion leads to a progressive decrease in the Tsk of the lower extremity, followed by rewarming during recovery. The observed inverse correlation between adipose tissue and Tsk, along with the distinct temperature trends in groups with varying levels of fat tissue, could imply that the skin and subcutaneous tissue complex may play a more intricate role in thermal energy exchange beyond its insulating function. This implies a multifaceted involvement of these tissues in thermoregulation.

Background: Breast cancer is the most common cancer among women. The number of cases is increasing among young women, and consequently, breast reconstructions are performed more often. Postoperative complications, wound healing, and the quality of scars influence the final cosmetic outcomes.

Stretchable electronics have significant applications in wearable applications. However, the extremely low thermal conductivity of elastic encapsulation hinders heat dissipation, leading to performance degradation. For instance, stretchable thermoelectric devices (TEDs) can be used for skin temperature regulation, but poor thermal management limits their cooling performance.

Thermosensory signals may contribute to the sense of body ownership, but their role remains highly debated. We test this assumption within the framework of pathological body ownership, hypothesising that skin temperature and thermoception differ between right-hemisphere stroke patients with and without Disturbed Sensation of Ownership (DSO) for the contralesional plegic upper limb. Patients with DSO exhibit lower basal hand temperatures bilaterally and impaired perception of cold and warm stimuli.

The study aimed to investigate the factors associated with early necrosis of the finger after reimplantation of broken fingers. Sixty-seven cases of reimplantation of severed fingers in our hospital between January 2023 and December 2023 were retrospectively analyzed. All patients underwent reimplantation of severed fingers and were divided into early necrosis group and non-necrosis group according to the presence or absence of early necrosis of the finger body 7 days after surgery.
