In a patient with septic arthritis and pressure ulcers requiring bilateral Girdlestone pseudoarthroplasty, hybrid open and closed incisional negative pressure therapy (ciNPT) is used to manage a closed surgical incision confluent with a large, open wound. Hybrid open and ciNPT facilitates both the healing of the primary closure as well as preparation of the wound bed for skin grafting. ciNPT can be used in partially closed wounds in combination with traditional NPT of the open portion of the wound to allow for more successful closure in wounds under tension.

Objective: Aim: To improve the results of treatment of patients with chronic wounds of the lower extremities by using complex treatment, including surgical interventions, VAC- therapy, as well as studying the effect of negative pressure on bacterial films of wounds, based on microbiological examination and immune-histochemical data.
Patients And Methods: Materials and Methods: During the period from 2019 to 2023 at the department's clinic, 68 patients with chronic wounds of the lower extremities were examined and treated. These are mainly women (n=63) aged from 35 to 80 years.

Extracorporeal shock wave therapy (ESWT) achieves its therapeutic purpose mainly through the biological effects produced by the interaction of shock waves with tissues, and the accurate measurement and calculation of the mechanical parameters of shock waves in tissues are of great significance in formulating the therapeutic strategy and evaluating the therapeutic effect. This study utilizes the approach of implanting flexible polyvinylidene fluoride (PVDF) vibration sensors inside the tissue-mimicking phantom of various thicknesses to capture waveforms at different depths during the impact process in real time. Parameters including positive and negative pressure changes (P, P), pulse wave rise time ([Formula: see text]), and energy flux density (EFD) are calculated, and frequency spectrum analysis of the waveforms is conducted.

RNA viruses have high genetic diversity, allowing rapid adaptation to environmental pressures, such as disinfection. This diversity increases the likelihood of mutations influencing the viral sensitivity to disinfectants. Ethanol is widely used to control viral transmission; however, insufficient disinfection facilitates the survival of less-sensitive viruses.

Stomata control plant water loss and photosynthetic carbon gain. Developing more generalized and accurate stomatal models is essential for earth system models and predicting responses under novel environmental conditions associated with global change. Plant optimality theories offer one promising approach, but most such theories assume that stomatal conductance maximizes photosynthetic net carbon assimilation subject to some cost or constraint of water.

Background/purpose: With the gradual aging of the population, oral health has emerged as a critical concern alongside mental well-being. This study endeavored to investigate the relationship between oral health-related quality of life (OHRQoL) and mental depression in middle-aged and older population.
Materials And Methods: Based on the Taiwan Longitudinal Study on Aging in 2015, 7631 participants were enrolled.
