Background: Tuberculosis (TB) is a widespread infectious disease, with an incidence that is increasing worldwide. Cutaneous TB (CTB) occurs rarely, accounting for less than 1% of all TB cases. Due to the clinical presentation and diagnostic difficulties, CTB is often clinically neglected and misdiagnosed.

Case Summary: A 32-year-old man underwent several debridement surgeries and skin flap transplantation after trauma. The wound remained unhealed, accompanied by sinus formation. According to empirical judgment, T-cell spot of TB test, and bacterial culture of pyogenic fluids, he was diagnosed with CTB due to infection with exogenous . A comprehensive anti-TB regimen that included isoniazid, rifampicin, ethambutol, and pyrazinamide was applied. The sinus was filled with a hydrophilic fiber-containing silver dressing, and wound-protecting sponges were applied to part of the wound. The wound healed after 40 d. No ulceration was found within 2 mo after discharge; further follow-up will be conducted.

Conclusion: A non-healing wound may be caused by TB infection. Comprehensive treatment of CTB is effective.

Background: Animal-assisted interventions (AAIs) have emerged as a promising nonpharmacological intervention option for children diagnosed with attention-deficit/hyperactivity disorder (ADHD). However, recent systematic reviews have been primarily narrative. Additionally, the pooled effectiveness of AAIs was absent from these systematic reviews.

The surface morphology of the developing mammalian brain is crucial for understanding brain function and dysfunction. Computational modeling offers valuable insights into the underlying mechanisms for early brain folding. Recent findings indicate significant regional variations in brain tissue growth, while the role of these variations in cortical development remains unclear.

Exosomes are integral to the pathophysiology of osteoarthritis (OA) due to their roles in mediating intercellular communication and regulating inflammatory processes. Exosomes are integral to the transport of bioactive molecules, such as proteins, lipids and nucleic acids, which can influence chondrocyte behavior and joint homeostasis. Given their properties of regeneration and ability to target damaged tissues, exosomes represent a promising therapeutic avenue for OA treatment.

Improving Renal Protection in Chronic Kidney Disease Associated with Type 2 Diabetes: The Role of Finerenone.

Endocr Metab Immune Disord Drug Targets

Chronic kidney disease (CKD) is a major complication of type 2 diabetes mellitus (T2D), which often leads to diabetic kidney disease (DKD). Traditional therapies, including renin- angiotensin-aldosterone system inhibitors and sodium-glucose cotransporter-2 inhibitors, are effective in slowing CKD progression. However, these approaches are insufficient to comprehensively inhibit mineralocorticoid receptor (MR) overactivation in the kidneys, which remains a significant driver of inflammation, fibrosis, and oxidative stress.
