Cultural competency and ethical behavior for collaboration in limited-resource settings: Guidelines from the Society of University Surgeons Academic Global Surgery Committee and the Association for Academic Global Surgery.

Background: There are an increasing number of global surgery activities worldwide. With such tremendous growth, there is a potential risk for untoward interactions between high-income country members and low-middle income country members, leading to programmatic failure, poor results, and/or low impact.

Methods: Key concepts for cultural competency and ethical behavior were generated by the Academic Global Surgery Committee of the Society for University Surgeons in collaboration with the Association for Academic Global Surgery.

Percutaneous kidney biopsies in children: a 24-year review in a tertiary center in northern Portugal.

Introduction: Percutaneous kidney biopsy (KB) is crucial to the diagnosis and management of several renal pathologies. National data on native KB in pediatric patients are scarce. We aimed to review the demographic and clinical characteristics and histopathological patterns in children who underwent native percutaneous KB over 24 years.

Smartphone addiction and postural alterations in the cervical region in adolescents.

Objective: To evaluate smartphone addiction and postural alterations in the cervical region in adolescents.

Methods: A cross-sectional study with 281 adolescents (15 to 19 years old), attending the 1st to the 3rd grades of High School, carried out between September and October 2019 in the city of Fortaleza, Ceará, Brazil. Data collection took place in two stages.

Lissencephaly With Cerebellar Hypoplasia Due To a New RELN Mutation.

Lissencephaly with cerebellar hypoplasia (LCH) is a rare variant form of lissencephaly, its distinctive neuroradiological phenotype being an important investigation clue regarding the potential involved genes, including variants in RELN gene. We report on a case of LCH whose clinical and neuroradiological features led to the identification of a homozygous pathogenic variant in RELN gene that has not been previously reported in the scientific literature.

Estimating the Glomerular Filtration Rate in Pediatric Patients With Neurogenic Bladder: A Comparison Between Creatinine- and Cystatin C-Equations.

Background and objective Patients with neurogenic bladder (NB) are at a higher risk of developing chronic kidney disease (CKD). Due to their lower muscle mass, the estimated glomerular filtration rate (eGFR) based on creatinine (Cr) may be overestimated and delay the diagnosis of renal failure. This study compared eGFR calculated with different equations based on Cr and/or cystatin C (CysC) in children with NB, and the differences between patients with lower muscle mass (underdeveloped lower limbs) and those with independent gait (less muscle depletion).

Everolimus as a therapeutic option in refractory epilepsy in children with tuberous sclerosis: a systematic review.

Background: Tuberous sclerosis (TS) is a multisystem genetic disease in which epilepsy is a frequent manifestation and is often difficult to control. Everolimus is a drug with proven efficacy in the treatment of other conditions related to TS, and some evidence suggests that its use benefits the treatment of refractory epilepsy in these patients.

Objective: To evaluate the efficacy of everolimus in controlling refractory epilepsy in children with TS.

Geographical Inequalities in Access to Bellwether Procedures in Brazil.

Background: Brazil is a middle-income country that aims to provide universal health coverage, but its surgical system's efficiency has rarely been analyzed. In an effort to strengthen surgical national systems, the Lancet Commission on Global Surgery proposed bellwether procedures as quality indicators of surgical workforces. This study aims to evaluate regional inequalities in access to bellwether procedures and their associated mortality across the five Brazilian geographical regions.

Two-Step In Vitro Model to Evaluate the Cellular Immune Response to SARS-CoV-2.

The cellular immune response plays an important role in COVID-19, caused by SARS-CoV-2. This feature makes use of in vitro models' useful tools to evaluate vaccines and biopharmaceutical effects. Here, we developed a two-step model to evaluate the cellular immune response after SARS-CoV-2 infection-induced or spike protein stimulation in peripheral blood mononuclear cells (PBMC) from both unexposed and COVID-19 (primo-infected) individuals (Step1).

Translation into Brazilian Portuguese and Cross-Cultural Adaptation of the NCCPC-PV for Pain Evaluation of Patients with Intellectual Disability to Communicate.

 To perform the translation and cross-cultural adaptation to Brazilian Portuguese of the Non-Communicating Children's Pain Checklist - Postoperative Version (NCCPC-PV) instrument, which assesses acute pain in individuals with severe intellectual disability (ID) who present great cognitive impairment and inability to communicate (CIIC).  In the adaptation process, the original NCCPC-PV was translated, back-translated, its versions were discussed by a committee of experts, and the resulting tool was tested in 20 health professionals and 20 caregivers of CCIC patients regarding its semantic clarity.  Data from the present study and its participants were analyzed and their results were described.
