Stroke remains a leading cause of global disability and mortality despite advancements in acute interventions. Transcranial direct current stimulation (tDCS), a non-invasive neuromodulation technique, has primarily been studied for its effects on cortical excitability, with limited exploration of its neuroprotective and hemodynamic benefits. This review examines the role of tDCS in stroke, with a focus on neuroprotection in acute settings and cerebral blood flow (CBF) modulation in both acute and chronic phases. tDCS offers rapid, localized delivery to salvageable ischemic tissue, exerting pleiotropic effects that address a broader spectrum of pathological processes compared to pharmacological agents. ⋯ Bihemispheric stimulation may offer additional benefits, with evidence suggesting a dose-dependent relationship between stimulation parameters and therapeutic outcomes. Further research is warranted to optimize stimulation protocols, evaluate safety and feasibility, and explore the potential of tDCS to promote neuroplasticity and functional recovery across different stroke populations and stages. By addressing these gaps, tDCS could emerge as a valuable adjunctive therapy in stroke management, complementing current interventions and expanding therapeutic windows.

Cognitive deficits are emerging as critical targets for managing schizophrenia and enhancing clinical and functional outcomes. These deficits are pervasive among individuals with schizophrenia, affecting various cognitive domains. ⋯ Understanding the mechanisms of neural circuits that underlie cognitive enhancement is essential for elucidating the pathophysiological processes of the disorder, and these insights could significantly optimize strategies for managing schizophrenia. Meanwhile, although there is an increasing body of evidence demonstrating the therapeutic effects of neuromodulation in this area, further research is still needed, particularly regarding topics such as different treatment protocols and the long-term effects of treatment.

Background and Objectives: In this study we analyzed the perceived effectiveness of cannabidiol (CBD) in adult women with inflammatory bowel disease (IBD). Materials and Methods: We conducted an online cross-sectional survey which assessed disease severity and quality of life (QOL) in women with IBD (Crohn's disease and ulcerative colitis) who used CBD versus those who did not. The survey included: the Harvey-Bradshaw Index, Partial Mayo Score, Short Inflammatory Bowel Disease Questionnaire, Bristol Stool Scale, and the Prime Screen Short Food Frequency Questionnaire. ⋯ Conclusions: Women with IBD who use CBD insignificantly trended toward improved disease-related symptoms, appetite, and QOL compared to non-users. Disease severity and QOL were inversely associated, regardless of CBD use. These preliminary outcomes indicate the need for further research on CBD use in women with IBD.

Background and Objectives: This study aimed to evaluate the role of A-PRF (advanced platelet-rich fibrin) in the enhancement of wound healing and protecting the periodontal health of mandibular second molars after the extraction of mandibular third molars. Additionally, the study assessed the levels of pro-inflammatory cytokines in the gingival crevicular fluid (GCF) of mandibular second molars as markers of inflammation. Materials and Methods: Twenty-five systemically healthy adult patients with bilateral removal of impacted mandibular third molars were included. ⋯ Pain and swelling scores were notably lower on the 7th postoperative day in the A-PRF group. A-PRF also reduced pro-inflammatory cytokines in GCF, significantly more than in control sites, at three months post-surgery. Conclusions: A-PRF enhances the periodontal and inflammatory status of adjacent teeth and wound healing after the extraction of mandibular third molars.

Exploring Reverse Sural Flap Necrosis in Lupus-like Syndrome: Challenges and Strategies in Lower Limb Reconstruction-A Case Presentation.
Soft tissue reconstruction in the lower limbs presents a significant challenge, particularly when addressing defects in the distal third of the leg, ankle, and foot. The reverse sural flap reliant on the perforating branches of the peroneal artery has emerged as a versatile option, offering a solution for patients for whom microsurgical techniques are not feasible. Despite its advantages, the procedure carries inherent risks, especially in populations with underlying conditions, such as venous insufficiency, cardiovascular disease, and diabetes, as well as in elderly patients, where the likelihood of flap necrosis is elevated. ⋯ The case illustrates not only the technical considerations and challenges associated with the reverse sural flap but also the broader implications of systemic autoimmune disorders on postoperative outcomes. Through a comprehensive review of the literature, we explore the relationship between vascularization, autoimmune profiles, and the success of reverse sural flap procedures. We highlight the critical need for surgeons to adopt a holistic approach to patient evaluation, considering both local and systemic factors that may influence the viability of the flap and the overall reconstructive success.
