Acute brachial plexopathy secondary to surgical management of an atrophic nonunion of a clavicle fracture.

We report the case of a 28-year-old patient who developed acute transient brachial plexopathy secondary to surgical management of an atrophic clavicle nonunion. The treatment was conservative, with symptom resolution at 4 months after surgery. This is the first reported case with electromyographic and neuroconduction follow-up, demonstrating complete and spontaneous resolution of axonal damage.

Anuran heart development and critical developmental periods: A comparative analysis of three neotropical anuran species.

The heart begins to form early during vertebrate development and is the first functional organ of the embryo. This study aimed to describe and compare the heart development in three Neotropical anuran species, Physalaemus albonotatus, Elachistocleis bicolor, and Scinax nasicus. Different Gosner Stages (GS) of embryos (GS 18-20) and premetamorphic (GS 21-25), prometamorphic (GS 26-41), and metamorphic (GS 42-46) tadpoles were analyzed using stereoscopic microscopy and Scanning Electronic Microscopy.

Insulin resistance indexes of grazing cows and mineral or vitamin supplementation under tropical conditions.

Background: During the transition period in dairy cows, metabolic changes occur, many of which are related to energy metabolism, which causes metabolic diseases or productive alterations.

Aim: The objective of the present work was to evaluate two mineral and vitamin supplementations related to metabolic regulation mechanisms associated with insulin during the transition period and the first phase of lactation in grazing cows under tropical conditions through metabolic indicators and insulin resistance indexes.

Methods: Twenty-one animals were distributed in three groups: control (CTR), iodine supplementation (SUPP-1), and mixed mineral and vitamin supplementation (SUPP-2).

Active Breaks Initiative During Hospital Rounds in the Surgical ICU to Improve Wellness of Healthcare Providers: An Observational Descriptive Study.

Background: Healthcare professionals in the intensive care unit (ICU) confront stressful working conditions. Morning rounds involve several hours of prolonged standing and uninterrupted concentration each day and require both mental and physical endurance from the entire care team. There is concern that work-related fatigue among ICU practitioners will compromise their ability to safely and effectively care for their patients.

Mesigyna once-a-month combined injectable contraceptive: experience in Latin America.

A phase III clinical study was carried out among 534 fertile Latin American women to evaluate cycle control, side effects, and contraceptive efficacy of a once-a-month combined injectable, Mesigyna, consisting of 50 mg norethisterone enanthate and 5 mg estradiol valerate. The pregnancy rate at 1 year was 0 per 100 woman-years for a total experience of 4688 woman-months. The overall discontinuation rate at one year was 17.
