Objective: Incidence of venous thromboembolism (VTE) and need for thromboprophylaxis in urologic surgery have received little attention since only one randomised study has addressed this issue in the last 20 yr. The present prospective observational study evaluated incidence and risk factors for clinically overt VTE in a wide spectrum of consecutive patients undergoing surgery for cancer and compared findings in urologic patients with those in patients undergoing general or gynaecologic surgery.
Methods: Patients having cancer surgery (general surgery, gynaecology, urology) were assessed for clinically overt VTE occurring up to 30+/-5 d after intervention or more if the hospital stay was longer. All suspected VTE events were evaluated by an external independent Adjudication Committee.
Results: A total of 2373 patients, 1238 (52%) undergoing general surgery, 685 (29%) urologic, and 450 (19%) gynaecologic surgery were evaluated. In urologic patients, most procedures (61%) were endoscopic, with bladder and prostate cancer being the most frequent tumours. In-hospital thromboprophylaxis was given to 71.7% of patients, whereas 32.5% received prophylaxis after discharge. The incidence of VTE in urologic patients was lower (0.87%) than that in general surgery and gynaecologic patients (2.8% and 2.0%, respectively). VTE consisted of three cases of nonfatal and three cases of fatal pulmonary embolism (PE). In four of the six cases, VTE occurred during prophylaxis.
Conclusions: VTE still represents a severe complication and remains the most common cause of death after urologic cancer surgery. Efforts should be made to optimise prophylactic measures to further reduce such risk.

A novel muscle network approach for objective assessment and profiling of bulbar involvement in ALS.

Introduction: As a hallmark feature of amyotrophic lateral sclerosis (ALS), bulbar involvement significantly impacts psychosocial, emotional, and physical health. A validated objective marker is however lacking to characterize and phenotype bulbar involvement, positing a major barrier to early detection, progress monitoring, and tailored care. This study aimed to bridge this gap by constructing a multiplex functional mandibular muscle network to provide a novel objective measurement tool of bulbar involvement.

Retrieving words quickly and correctly is an important language competence. Semantic contexts, such as prior naming of categorically related objects, can induce conceptual priming but also lexical-semantic interference, the latter likely due to enhanced competition during lexical selection. In the continuous naming (CN) paradigm, such semantic interference is evident in a linear increase in naming latency with each additional member of a category out of a seemingly random sequence of pictures being named (cumulative semantic interference/CSI effect).

The lung is a vital organ for the body as the main source of oxygen input. Importantly, it is also an internal organ that has direct contact with the outside world. Innate immunity is a vital protective system in various organs, whereas, in the case of the lung, it helps maintain a healthy, functioning cellular and molecular environment and prevents any overt damage caused by pathogens or other inflammatory processes.

Acromegaly is a rare endocrine disorder caused by excessive growth hormone (GH) production, due, in the vast majority of cases, to the presence of a GH-secreting pituitary tumour. The chronic elevation of GH and the resulting high circulating levels of insulin-like growth factor-1 (IGF-1) cause the characteristic tissue overgrowth and a number of associated comorbidities, including several metabolic changes, such as glucose intolerance and overt diabetes mellitus (DM). Elevated GH concentrations directly attenuate insulin signalling and stimulate lipolysis, decreasing glucose uptake in peripheral tissues, thus leading to the development of impaired glucose tolerance and DM.

Cirrhotic cardiomyopathy (CCM) is a diagnostic entity defined as cardiac dysfunction (diastolic and/or systolic) in patients with liver cirrhosis, in the absence of overt cardiac disorder. Pathogenically, CCM stems from a combination of systemic and local hepatic factors that, through hemodynamic and neurohormonal changes, affect the balance of cardiac function and lead to its remodeling. Vascular changes in cirrhosis, mostly driven by portal hypertension, splanchnic vasodilatation, and increased cardiac output alongside maladaptively upregulated feedback systems, lead to fluid accumulation, venostasis, and cardiac dysfunction.
