Preoperative Gabapentin for Pain Control: A Randomized, Placebo-controlled Clinical Trial in Patients Undergoing Inguinal Hernioplasty.

Purpose: The perioperative use of gabapentin has been suggested to reduce postoperative pain and opioid consumption. However, there is a variation in clinical practice, the type of surgery and the administration time seem to be distinct between the available studies. We assess whether gabapentin administered before surgery reduces postoperative pain in patients who have undergone inguinal hernioplasty.

Results of the Last 5 Years (2018-2022) of the Specialist Title Exam of The Brazilian College of Surgeons.

The article discusses the evolution of the Brazilian College of Surgeons (CBC) specialist title exam, highlighting the importance of evaluating not only theoretical knowledge, but also the practical skills and ethical behavior of candidates. The test was instituted in 1971, initially with only the written phase, and later included the oral practical test, starting with the 13th edition in 1988. In 2022, the assessment process was improved by including the use of simulated stations in the practical test, with the aim of assessing practical and communication skills, as well as clinical reasoning, in order to guarantee excellence in the assessment of surgeons training.

Analysis of the fight against the COVID-19 pandemic in long-term care facilities in the pre-vaccination period.

Introduction: The COVID-19 pandemic has disproportionately affected individuals residing in Long-Term Care Facilities (LTCFs), necessitating tailored strategies to manage outbreaks. This study examines the outcomes of the ILPI BH project, a collaborative effort between the Municipal Health Department and the Hospital das Clínicas of the Federal University of Minas Gerais, designed to mitigate COVID-19 spread within LTCFs.

Methods: Prospective cohort of secondary data: 1,794 old residents in 99 long-term care facilities of Belo Horizonte, Brazil, were followed from May 2020 to January 2021.

Clinical characteristics and outcomes in COVID-19 in kidney transplant recipients: a propensity score matched cohort study.

Patients with chronic kidney disease (CKD), especially those on dialysis or who have received a kidney transplant (KT), are considered more vulnerable to severe COVID-19. This susceptibility is attributed to advanced age, a higher frequency of comorbidities, and the chronic immunosuppressed state, which may exacerbate their susceptibility to severe outcomes. Therefore, our study aimed to compare the clinical characteristics and outcomes of COVID-19 in KT patients with those on chronic dialysis and non-CKD patients in a propensity score-matched cohort study.

To be or not to B27 positive: implications for the phenotypes of axial spondyloarthritis outcomes. Data from a large multiracial cohort from the Brazilian Registry of Spondyloarthritis.

Background: There is a remarkable variability in the frequency of HLA-B27 positivity in patients with spondyloarthritis (SpA), which may be associated with different clinical presentations worldwide. However, there is a lack of data considering ethnicity and sex on the evaluation of the main clinical and prognostic outcomes in mixed-race populations. The aim of this study was to evaluate the frequency of HLA-B27 and its correlation with disease parameters in a large population of patients from the Brazilian Registry of Spondyloarthritis (RBE).

Patients hospitalized with active tuberculosis and Covid-19 coinfection: A matched case-control from the Brazilian Covid-19 Registry.

Although control of Covid-19 has improved, the virus continues to cause infections, such as tuberculosis, that is still endemic in many countries, representing a scenario of coinfection. To compare Covid-19 clinical manifestations and outcomes between patients with active tuberculosis infection and matched controls. This is a matched case-control study based on data from the Brazilian Covid-19 Registry, in hospitalized patients aged 18 or over with laboratory confirmed Covid-19 from March 1, 2020, to March 31, 2022.

Torsion of the inferior vena cava: An unprecedented variant of post-pneumonectomy syndrome.

Post-pneumonectomy syndrome (PPS) is a rare complication after pneumonectomy defined by mediastinum shift toward the vacated pleural space with compression of the distal trachea or mainstem bronchi, resulting in dyspnea. This report describes a 32-year-old woman who presents with limiting symptoms of progressive dyspnea and chest pain 2 years after a right pneumonectomy. In computed tomography scan, there was no evidence of airway compression but suggested torsion of the inferior vena cava with preload compromise, confirmed during the surgical mediastinum repositioning using a transesophageal echocardiography-guided approach.
