Heart rate variability-based prediction of early cardiotoxicity in breast-cancer patients treated with anthracyclines and trastuzumab.

Background: Cardiotoxicity is a recognized complication in breast cancer (BC) patients undergoing chemotherapy with anthracyclines with or without trastuzumab. However, the prognostic value of heart rate variability (HRV) indexes for early cardiotoxicity development remains unknown.

Methods: Fifty BC patients underwent TTE assessment before and three months after chemotherapy.

Bariatric Surgery Before and After the SARS-CoV-2 Pandemic: a Comparative Study of Cases Before the Onset of the Pandemic in a High-Volume Academic Center.

Introduction: At the beginning of the pandemic, studies showed a higher risk of severe surgical complications and mortality among patients with perioperative SARS-CoV-2 infection, which led to the suspension of elective surgery. Confinement and lockdown measures were shown to be associated with weight gain and less access to medical and surgical care in patients with obesity, with negative health consequences. To evaluate the safety of bariatric surgery during the pandemic, we compared 30-day complications between patients who underwent bariatric surgery immediately before with those who underwent bariatric surgery during the opening phase of the pandemic.

Isolation of VGIII from feline nasal injury.

Hereby we communicate the first autochthon isolation of VGIII in Chile, which was obtained from a nasal injury in a domestic cat in the Valparaíso region in Chile. The strain was identified using morphophysiological tests, MALDI-TOF, and URA5 gene PCR-RFLP analysis.

Capillary refill time during fluid resuscitation in patients with sepsis-related hyperlactatemia at the emergency department is related to mortality.

Introduction: Acute circulatory dysfunction in patients with sepsis can evolve rapidly into a progressive stage associated with high mortality. Early recognition and adequate resuscitation could improve outcome. However, since the spectrum of clinical presentation is quite variable, signs of hypoperfusion are frequently unrecognized in patients just admitted to the emergency department (ED).

Motion clouds: model-based stimulus synthesis of natural-like random textures for the study of motion perception.

Choosing an appropriate set of stimuli is essential to characterize the response of a sensory system to a particular functional dimension, such as the eye movement following the motion of a visual scene. Here, we describe a framework to generate random texture movies with controlled information content, i.e.

Management of leaks after laparoscopic sleeve gastrectomy in patients with obesity.

Introduction: Laparoscopic sleeve gastrectomy (LSG) is a surgical procedure that is being increasingly performed on obese patients. The most frequent postoperative complication is the appearance of a gastric leak.

Purpose: To determine the main clinical features of a group of patients who developed a gastric leak after LSG.

The effect of different isoflurane-fentanyl dose combinations on early recovery from anesthesia and postoperative adverse effects.

Unlabelled: We evaluated the effect of different combinations of fentanyl-isoflurane on early recovery from anesthesia in 80 adult patients undergoing laparoscopic cholecystectomy. Anesthesia was induced with fentanyl 2 microg/kg and thiopental 5 mg/kg. Nitrous oxide was not used and patients were randomly assigned to one of four groups: Group 1 (n = 20) received 0.
