Main pulmonary artery diameter related to pneumonia severity.

The diameter (mPAD) of the main pulmonary artery (pulmonary artery trunk) is a crucial indicator for cardiovascular health and prognoses in various conditions. Its enlargement is associated with increased mortality and severity in COVID-19-related pneumonia. However, its relevance to non-COVID pneumonia remains uncertain.

Initial evaluation and external validation of 68Ga-PSMA-11 PET/CT in tubarial gland characterization.

Introduction: Radiotracer Ga-PSMA-11 used in PET/CT scans allows for identification and localization of gland tissue. It allows for their consideration in clinical scenarios and to design further and stronger research to answer pertinent questions regarding their function and implications. We aimed to externally validate first reported findings of location, size, and ligand uptake of the tubarial glands using Ga-PSMA-11 PET/CT.

Rotator Interval vs Posterior Approach Ultrasound-guided Corticosteroid Injections in Primary Frozen Shoulder: A Meta-analysis of Randomized Controlled Trials.

Objective: To compare the efficacy of rotator interval (RI) vs posterior approach (PA) ultrasound (US) guided corticosteroid injections into the glenohumeral (GH) joint in primary frozen shoulder (PFS).

Data Sources: A systematic literature search for all relevant studies on Medline, Scopus, Embase, Web of Science, and Cochrane Central, up to January 2023 was conducted.

Study Selection: Randomized controlled trials that directly compared the US-guided corticosteroid injection into the RI and GH joint using PA in patients clinically and radiographically diagnosed with PFS.

Gallbladder perforation with fistulous communication.

Background: The management of gallbladder perforation (GBP) with fistulous communication (Neimeier type I) is controversial.

Aim: To recommend management options for GBP with fistulous communication.

Methods: A systematic review of studies describing the management of Neimeier type I GBP was performed according to the PRISMA guidelines.

Assessment of burnout syndrome and associated factors among medical students during the COVID-19 pandemic.

Overwhelming requirements, a high degree of work, and prolonged exposure to emotionally demanding circumstances in work and life settings can lead to burnout syndrome. The purpose of the study is to assess burnout syndrome and its associated factors among medical students during the COVID-19 pandemic. A cross-sectional, prospective, descriptive study was conducted in a Mexican medical school during the last week of the spring semester of 2021 using the Maslach Burnout Inventory-Student Survey (MBI-SS) and an associated factors survey.

Fetal-type posterior cerebral artery and association of rupture in posterior communicating artery aneurysms: A systematic review and meta-analysis.

Background: The morbidity and mortality of intracranial aneurysm rupture motivate the risk evaluation of the patient´s characteristics and aneurysm's morphology. Brain vessel variants lead to hemodynamic changes that could increase risk. This study aims to evaluate the fetal posterior cerebral artery (fPCA) as a risk factor for the formation, rupture, and recurrence of the posterior communicating artery (PComA) aneurysm.

Payment with knowledge: A method for a training of anatomy near-peer teachers and formation of future anatomists.

Near-peer teaching has been widely implemented in medical schools and the benefits for the near-peer teachers (NPTs), the students, and the institution have been well documented. However, NPT training methods and perceptions of such have been limited. A four-year clinical anatomy and surgical training program was established (est.

In Vivo Models for the Study of Hyaluronic Acid Fillers: A Review.

Background: Hyaluronic acid (HA) filler application is one of the most frequent minimally invasive aesthetic procedures used worldwide. Its properties and characterization, performance, effects in other tissues, and response to complication treatments have been studied in several animal models. This review aims to categorize animal models considering the advantages and disadvantages regarding the purpose of the study.

Aged rats learn Morris Water maze using non-spatial search strategies evidenced by a parameter-based algorithm.

Spatial learning and memory are used by all individuals who need to move in a space. Morris water maze (MWM) is an accepted method for its evaluation in murine models and has many protocols, ranging from the classic parameters of latency, distance, and number of crossings to the platform zone, to other more complex methods involving computerized trajectory analysis. Algorithm-based SS analysis is an alternative that enriches traditional classic parameters.

Trendelenburg (Head-Down tilt) and head rotation: Ultrasonographic effects on the internal jugular vein for catheterization safety.

Most guidelines fail to specify patient positioning during central venous catheterization. The objective was to determine the effects of head-down tilt (Trendelenburg position) and head rotation on the internal jugular vein (IJV). A prospective, observational, longitudinal, and descriptive study using healthy adult volunteers, of both sexes, was performed.

Trendelenburg position for internal jugular vein catheterization: A systematic review and meta-analysis.

To determine the effect of Trendelenburg position on the diameter or cross-section area of the internal jugular vein (IJV) a systematic review and metanalysis was performed. Studies that evaluated the cross-sectional area (CSA) and anteroposterior (AP) diameter of the right internal jugular vein (RIJV) with ultrasonography in supine and any degree of head-down tilt (Trendelenburg position) were analyzed. A total of 22 articles (613 study subjects) were included.

Hippocampal volume as treatment predictor in antidepressant naïve patients with major depressive disorder.

Major depression disorder (MDD) limits psychosocial functioning and quality of life. One of the biological alterations is a hippocampal volume (HV) reduction. Previous prospective neuroimaging studies present inconsistencies regarding HV reductions and clinical features and response of antidepressant treatment of the participants.
