Objective: Robotic gynecological surgery is feasible in obese patients, but there remain concerns about the safety of this approach because the positioning required for pelvic surgery can exacerbate obesity-related changes in respiratory physiology. The objective of our study was to evaluate pulmonary and all-cause complication rates in obese women undergoing robotic gynecological surgery and to assess variables that may be associated with complications.
Study Design: A retrospective chart review was performed on obese patients (body mass index of ≥30 kg/m(2)) who underwent robotic gynecological surgery at 2 academic institutions between 2006 and 2012. The primary outcome was pulmonary complications and the secondary outcome was all-cause complications. Univariate and multivariate logistic regression analyses were used to determine the associations between patient baseline variables, operative variables, ventilator parameters, and complications.
Results: Of 1032 patients, 146 patients (14%) had any complication, whereas only 33 patients (3%) had a pulmonary complication. Median body mass index was 37 kg/m(2). Only age was significantly associated with a higher risk of pulmonary complications (P = .01). Older age, higher estimated blood loss, and longer case length were associated with a higher rate of all-cause complications (P = .0001, P < .0001, and P = .004, respectively). No other covariates were strongly associated with complications.
Conclusion: The vast majority of obese patients can successfully tolerate robotic gynecological surgery and have overall low complications rates and even lower rates of pulmonary complications. The degree of obesity was not predictive of successful robotic surgery and subsequent complications.

Posaconazole for Prevention of COVID-19-Associated Pulmonary Aspergillosis in Mechanically Ventilated Patients: A European Multicentre Case-Control Study (POSACOVID).

Background: This study investigated the impact of posaconazole (POSA) prophylaxis in COVID-19 patients with acute respiratory failure receiving systemic corticosteroids on the risk for the development of COVID-19-associated pulmonary aspergillosis (CAPA).
Methods: The primary aim of this prospective, multicentre, case-control study was to assess whether application of POSA prophylaxis in mechanically ventilated COVID-19 patients reduces the risk for CAPA development. All consecutive patients from centre 1 (cases) who received POSA prophylaxis as standard-of-care were matched to one subject from centre 2 and centre 3 who did not receive any antifungal prophylaxis, using propensity score matching for the following variables: (i) age, (ii) sex, (iii) treatment with tocilizumab and (iv) time at risk.

Background: The early stages of tumor bone metastasis are closely associated with changes in the vascular niche of the bone microenvironment, and abnormal angiogenesis accelerates tumor metastasis and progression. However, the effects of lung adenocarcinoma (LUAD) cells reprogrammed by the bone microenvironment on the vascular niche within the bone microenvironment and the underlying mechanisms remain unclear. This study investigates the effects and mechanisms of LUAD cells reprogrammed by the bone microenvironment on endothelial cells and angiogenesis, providing insights into the influence of tumor cells on the vascular niche within the bone microenvironment.

Background: Preterm prelabor rupture of membranes (PPROM) before or around the limit of fetal viability is associated with serious maternal and neonatal complications including chorioamnionitis, extremely preterm birth, and pulmonary hypoplasia.
Objectives: To describe contemporary outcomes of extremely preterm infants born after prolonged periviable PPROM, and to identify perinatal factors associated with survival and survival without severe neurodevelopmental impairment (NDI).
Study Design: Among actively treated infants born alive at <27 weeks' gestational age (GA) in centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network from 2012 to 2018, the outcomes of survival and survival without severe NDI at 22-26 months' corrected age were compared between infants exposed to prolonged (≥120 hours) periviable (<24 weeks' GA) PPROM and unexposed infants born after rupture of membranes ≤18 hours before delivery or at delivery, adjusting for birth GA, sex, multiple gestation, antenatal steroids, small for gestational age (SGA), insurance, and center.

[F]FDG PET/TC is an emerging tool in the evaluation of inflammatory arthropathies, characterised by their insidious course and clinical overlap. It allows detection of subclinical inflammation, assessment of systemic involvement and quantification of metabolic parameters useful in early diagnosis and therapeutic monitoring. In rheumatoid arthritis, it correlates with clinical indices (Disease Activity Score), serological markers (CRP, anti-citrullinated protein antibodies) and ultrasound findings, and facilitates the identification of complications such as cardiovascular and pulmonary involvement.
