Introduction And Aim Of The Study: A notable proportion of COVID outbreaks are generated by "super-spreading events", where a few subjects transmit the pathogen to many secondary cases, increasing contact networks and the spread of the pathogen. We conducted a description of a COVID-19 superspreading event in Córdoba during July 2020, linked to a nightlife establishment.
Material And Methods: Retrospective observational study describing characteristics of person, time, PCR result and contact network of confirmed cases. PCR results in Córdoba during July and August and information collected in surveillance systems were analyzed.
Results: 935 individuals associated with the outbreak were included; 120 (12.83%) became confirmed cases. July 17 was the day with the highest incidence, with 27 new cases (22.5% of the total). People under 25 years old represented 69.2% of the cases. The average number of close contacts per person was 10.7, with a decrease as age raised. During the outbreak, incidence increased at the provincial level compared to previous weeks; at the end, incidence did not return to initial values but remained high with a relevant percentage of cases having unknown epidemiological association.
Conclusions: A greater transmission capacity of SARS-CoV-2 was observed in a closed, crowded space, and among young people that tended to report a greater number of social contacts and may present little or no symptoms. Developing preventive measures in scenarios that combine these factors and early detection of cases are essential to avoid an increase in the spread of the virus.

Background: Achieving a stable vasculature is crucial for tissue regeneration. Endothelial cells initiate vascular morphogenesis, followed by mural cells that stabilize new vessels. This study investigated the in vivo effects of Sema4D-Plexin-B1 signaling on stem cells from human exfoliated deciduous teeth (SHED)-supported angiogenesis, focusing on its mechanism in PDGF-BB secretion.

Background: Iliac vein compression syndrome (IVCS) impedes venous blood return from the lower extremities due to iliac vein compression, manifesting as leg swelling, varicose veins, and thrombosis. These symptoms significantly degrade quality of life. Although iliac vein stenting provides symptomatic relief, the recovery process is protracted and fraught with challenges such as in-stent restenosis and psychological distress.

Purpose: Pediatric health outcomes are often assessed using proxy reports, which may not fully capture children's experiences. Children with surgical conditions face unique, changing healthcare journeys, making accurate representation challenging. This review compares child-reported health status and treatment experiences from Patient-Reported Outcome Measures (PROMs) and Patient-Reported Experience Measures (PREMs) with parent reports.

Background: Conversional surgery following sleeve gastrectomy (SG) is required in about 20 % of patients due to suboptimal outcomes. Single anastomosis duodenoileal bypass (SADI) has emerged as an option for such cases, though long-term outcomes remain unclear. This review analyzed available data on SADI as a conversional or second-stage procedure after SG.

Background: A previous Australia-wide pilot study identified pain as a significant burden in people with CF (pwCF). However, the prevalence, frequency and severity have not been evaluated using validated tools.
Methods: Australian adults, pwCF and healthy controls (HC) were invited to complete an online questionnaire from July 2023 - February 2024, consisting of four validated tools: Brief Pain Inventory, Pain Catastrophising Scale, PAGI-SYM and PAC-SYM.
