Management of pilonidal sinus and recurrences in 2025.

Pilonidal sinus is a common pathology of the intergluteal cleft that can develop into abscess or suppuration. This lesion corresponds histologically to a granuloma that organizes around foreign bodies, most often hairs, and fistulizes to the skin through partially epithelialized orifices. If suppuration and abscess develop, treatment is based either on medical treatment combining analgesics, local antiseptics and sometimes antibiotics, or on emergency incision and drainage in the operating room.

Predicting Microbial Protein Synthesis in Cattle: Evaluation of Extant Equations and Steps Needed to Improve Accuracy and Precision of Future Equations.

Predictions of microbial crude protein (MCP) synthesis for beef cattle generally rely on empirical regression equations, with intakes of energy and protein as key variables. Using a database from published literature, we developed new equations based on the intake of organic matter (OM) and intakes or concentrations of crude protein (CP) and neutral detergent fiber (NDF). We compared these new equations to several extant equations based on intakes of total digestible nutrients (TDN) and CP.

Enhancing the Anticancer Activity of Attenuated by Cell Wall Functionalization with "Clickable" Doxorubicin.

Among bacteria used as anticancer vaccines, attenuated (Lm) stands out, because it spreads from one infected cancer cell to the next, induces a strong adaptive immune response, and is suitable for repeated injection cycles. Here, we use click chemistry to functionalize the Lm cell wall and turn the bacterium into an "intelligent carrier" of the chemotherapeutic drug doxorubicin. Doxorubicin-loaded Lm retains most of its biological properties and, compared to the control fluorophore-functionalized bacteria, shows enhanced cytotoxicity against melanoma cells both in vitro and in a xenograft model in zebrafish.

Complication, vertical bone gain, volumetric changes after vertical ridge augmentation using customized reinforced PTFE mesh or Ti-mesh. A non-inferiority randomized clinical trial.

Objective: The aim of this non-inferiority randomized clinical trial was to compare the surgical and healing complications, vertical bone gain, and volumetric bone changes after vertical ridge augmentation using two different approaches: customized Ti-reinforced d-PTFE mesh versus customized CAD/CAM Ti-mesh.

Materials And Methods: Fifty patients with vertical bone defects were randomly treated with Ti-reinforced d-PTFE mesh (control group) or CAD/CAM Ti-mesh (test group) and a mix of autogenous bone and deproteinized bovine bone matrix. Surgical and healing complication rates (SCR-HCR), vertical bone gain (VBG), regenerated bone volume (RBV), and regeneration rates (RR and ERR) were recorded and analysed [significance level (α) of 0.
