On a Hunt for the "True" Septocutaneous Perforator: A Histology Cross-Section Study.

Background:  Modern trends in reconstructive surgery involve the use of free perforator flaps to reduce the donor site morbidity. The course of perforator vessels has a great anatomic variability and demands detailed knowledge of the anatomical relationships and the variability of the course of the perforators. The numerous modifications to perforator nomenclature proposed by various authors resulted in confusion rather than simplification.

People with HIV exhibit spectrally distinct patterns of rhythmic cortical activity serving cognitive flexibility.

Despite effective antiretroviral therapy, cognitive impairment remains prevalent among people with HIV (PWH) and decrements in executive function are particularly prominent. One component of executive function is cognitive flexibility, which integrates a variety of executive functions to dynamically adapt one's behavior in response to changing contextual demands. Though substantial work has illuminated HIV-related aberrations in brain function, it remains unclear how the neural oscillatory dynamics serving cognitive flexibility are affected by HIV-related alterations in neural functioning.

Preventing Recurrence of Crohn's Disease Post-Ileocaecal Surgery in Paediatric Patients: A Therapy Guide Based on Systematic Review of the Evidence.

Background And Aims: Ileocaecal resection (ICR) is frequent in paediatric patients with Crohn's disease (pCD). Despite rates of reoperation being low, the risk of clinical or endoscopic post-operative recurrence (POR) is high; effective medical strategies to prevent POR are thus needed. The aim of this systematic review (SR) was to identify and evaluate the published literature on post-operative medical prevention of POR in pCD to draft a possible therapy guide for pCD patients undergoing ICR.

History of surgical treatment of lymphatic drainage at the Department of Plastic and Aesthetic Surgery, St. Anne's University Hospital in Brno.

The Department of Plastic and Aesthetic Surgery, St. Anne's University Hospital in Brno, and Faculty of Medicine of Masaryk University, Brno, has a long history of surgical treatment of lymphedema and elephantiasis, which started in 1970s. There were many types of surgeries described and performed at our department - starting with prof.

Spontaneous cortical activity is altered in persons with HIV and related to domain-specific cognitive function.

Whilst the average lifespan of persons with HIV now approximates that of the general population, these individuals are at a much higher risk of developing cognitive impairment with ∼35-70% experiencing at least subtle cognitive deficits. Previous works suggest that HIV impacts both low-level primary sensory regions and higher-level association cortices. Notably, multiple neuroHIV studies have reported elevated levels of spontaneous cortical activity during the pre-stimulus baseline period of task-based experiments, but only a few have examined such activity during resting-state conditions.
