Behavior of immunoglobulin G antibodies for SARS-COV-2 in Mexican pediatric patients with comorbidities: a prospective comparative cohort study.

Background: More than two years after the pandemic of COVID-19 caused by the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) there is a great lack of information. The presence of immunoglobulin G (IgG) have been related with disease severity. Patients with comorbidities could develop more severe infection; however, the evaluation of the humoral response in pediatric population are needed especially in patients with comorbidities.

Analysis of GPR126 polymorphisms and their relationship with scoliosis in Marfan syndrome and Marfan-like syndrome in Mexican patients.

Marfan syndrome (MFS) is an inherited connective tissue disorder. As the spinal growth depends on delicate balance of forces, conditions that affect musculoskeletal matrix often lead to spinal deformities. A large cross-sectional study revealed a 63% prevalence of scoliosis among patients with MFS.

Long COVID in children and adolescents: COVID-19 follow-up results in third-level pediatric hospital.

Introduction: In children, the manifestations of coronavirus disease 2019 (COVID-19) in the acute phase are considered mild compared with those in adults; however, some children experience a severe disease that requires hospitalization. This study was designed to present the operation and follow-up results of the Post-COVID-19 Detection and Monitoring Sequels Clinic of Hospital Infantil de Mexico Federico Gómez in managing children with a history of SARS-CoV-2 infection.

Methods: This was a prospective study conducted from July 2020 to December 2021, which included 215 children aged 0-18 years who tested positive for SARS-CoV-2 on polymerase chain reaction and/or immunoglobulin G test.

Cardiothoracic surgery and peripheral endovascular intervention in cardiovascular damage from a cohort of orphan rheumatological diseases-epidemiological and survival analysis.

Background: Aortic diseases in some orphan rheumatological diseases require medical, surgical or peripheral endovascular intervention because they can be catastrophic. Objectives: to analyze the main clinical and epidemiological characteristics of patients with Takayasu arteritis (TA), Marfan syndrome (MS) and similar conditions that were treated with cardiothoracic surgery and peripheral endovascular intervention.

Methods: Retrospective and descriptive cohort study that included patients of any age and gender with TA (as per the criteria of the American College of Rheumatology and EULAR/PRINTO), MS (according to Ghent criteria), and similar conditions who underwent cardiothoracic surgery or peripheral endovascular intervention.

Failures of the Fontan System in Univentricular Hearts and Mortality Risk in Heart Transplantation: A Systematic Review and Meta-Analysis.

The Fontan procedure (FP) is the standard surgical treatment for Univentricular heart diseases. Over time, the Fontan system fails, leading to pathologies such as protein-losing enteropathy (PLE), plastic bronchitis (PB), and heart failure (HF). FP should be considered as a transitional step to the final treatment: heart transplantation (HT).

Systematic review and meta-analysis of aortic valve-sparing surgery versus replacement surgery in ascending aortic aneurysms and dissection in patients with Marfan syndrome and other genetic connective tissue disorders.

Background: Aortic aneurysm and dissection are important causes of morbimortality in patients with Marfan syndrome (MFS) and other connective tissue diseases that affect the cardiovascular tissues. Timely intervention through different surgical techniques improves the prognosis. Both sparing and replacement-type interventions of the aortic valve are used, but selection depends on the condition of the patient at the time of diagnosis, the patient's emergency condition, surgeon preference and hospital resources.

The impact of improving the quality of coding in the utilities of Diagnosis Related Groups system in a private healthcare institution. 14-year experience.

Background And Project Aim: The American British Cowdray Medical Center is a private healthcare institution in Mexico City. One of the many tools that we use and help us to achieve a high standard of quality and recognition worldwide is the clinical coding and Diagnosis Related Groups (DRG). To help the readers to improve the process of clinical coding, we will share the challenges, changes and different applications of the generation of DRG in the private healthcare institution.
