Predictors of prolonged hospital stay in patients undergoing lung resection.

Purpose: To identify potential predictors of prolonged length of hospital stay in patients submitted to lung resection surgery.

Materials And Methods: This is a cohort study, carried out in 105 patients with lung cancer, submitted to posterolateral thoracotomy pulmonary resection. Data collection included preoperative assessment of demographic, clinical, pulmonary function, respiratory muscle function, physical fitness, and behavioral habits.

Relationship between type 2 diabetes mellitus and markers of cutaneous melanoma aggressiveness: an observational multicentric study in 443 patients with melanoma.

Background: Some studies have suggested a relationship between type 2 diabetes mellitus (T2DM) and increased incidence of melanoma. Efforts are under way to identify preventable and treatable factors associated with greater melanoma aggressiveness, but no studies to date have examined the relationship between T2DM and the aggressiveness of cutaneous melanoma at diagnosis.

Objectives: To explore potential associations between T2DM, glycaemic control and metformin treatment and the aggressiveness of cutaneous melanoma.

Development and Validation of an Analytical Method for Volatiles with Endogenous Production in Putrefaction and Submersion Situations.

A group of 16 volatile substances (ethyl acetate, 2-propanol, 1-propanol, methanol, acetone, ethanol, acetaldehyde, diethyl ether, methyl ethyl ketone, 1-butanol, 2-butanol, t-butanol, isobutanol, 2-methyl-1-butanol, 3-methyl-1-butanol and 1-pentanol) were qualitatively and quantitatively analyzed through a method developed for volatiles with endogenous production in putrefaction and submersion situations. The method was validated for blood, urine and vitreous humor, using a gas chromatograph (Varian 450-GC) with a flame ionization detector coupled to a headspace injector (HS-GC-FID). The vials were prepared by diluting 100 µL of the sample of interest in 1 mL of internal standard (acetonitrile 100 mg/L), using two capillary columns (VF-624ms and VF-5ms) with different polarities to ensure that all test compounds would be properly identified and undoubtedly distinguished from the rest.

Sleep quality in times of Covid-19 pandemic.

Background: Due to the 2019 novel coronavirus (COVID-19) disease outbreak, social distancing measures were imposed to control the spread of the pandemic. However, isolation may affect negatively the psychological well-being and impair sleep quality. Our aim was to evaluate the sleep quality of respiratory patients during the COVID-19 pandemic lockdown.

Influence of Respiratory Muscle Training on Patients' Recovery after Lung Resection.

This prospective experimental study aimed to compare effects of 3 different home-based postoperative respiratory muscle training protocols - inspiratory, expiratory and combined, in the patients' postoperative recovery, regarding safety and respiratory muscle function, pulmonary function, physical fitness, physical activity (PA), dyspnoea and quality of life (QoL). Patients were divided in four groups Usual Care (UCare), inspiratory (IMT), expiratory (EMT) or combined muscle training (CombT) according to group allocation. Significant treatment*time interactions were found for maximal inspiratory pressure (MIP) (p=0.
