Association Between Alpha Angle and Acetabular Index in Screening for Developmental Dysplasia of the Hip.

Background: Developmental dysplasia of the hip (DDH) is a critical orthopedic condition ranging from minor hip joint instability to complete dislocations, demanding early intervention to avoid severe complications, especially in children. In Mexico, stringent regulations under the Norma Oficial Mexicana (NOM) mandate hip screening for pediatric patients. The primary objective of this study is to investigate the relationship between alpha angles and the acetabular index in patients at six months of age, aiming to determine whether an increase in the alpha angle correlates with a better acetabular index.

Fungal coinfection/superinfection in COVID-19 patients in a tertiary hospital in Mexico.

Introduction: Data on the prevalence of fungal coinfections/superinfections in patients with COVID-19 are limited.

Objective: To describe the prevalence of fungal coinfections/superinfections in patients with COVID-19, as well as risk factors and demographic, clinical, and microbiological characteristics.

Material And Methods: We included patients with a confirmed COVID-19 diagnosis and a confirmed fungal infection hospitalized in the ICU from March 2020 to December 2021.

Which Side of the Coin Are You on Regarding Possible Postnatal Oogenesis?

It is well known that oocytes are produced during fetal development and that the total number of primary follicles is determined at birth. In humans, there is a constant loss of follicles after birth until about two years of age. The number of follicles is preserved until the resumption of meiosis at puberty and there is no renewal of the oocytes; this dogma was maintained in the last century because there were no suitable techniques to detect and obtain stem cells.

Longitudinal multiomics analysis of aggressive pituitary neuroendocrine tumors: comparing primary and recurrent tumors from the same patient, reveals genomic stability and heterogeneous transcriptomic profiles with alterations in metabolic pathways.

Pituitary neuroendocrine tumors (PitNET) represent the vast majority of sellar masses. Some behave aggressively, growing rapidly and invading surrounding tissues, with high rates of recurrence and resistance to therapy. Our aim was to establish patterns of genomic, transcriptomic and methylomic evolution throughout time in primary and recurrent tumors from the same patient.

Modified thoracoabdominal nerve block via perichondral approach: an alternative for perioperative pain management in laparoscopic cholecystectomy in a middle-income country.

Background: Laparoscopic cholecystectomy is known for its minimally invasive nature, but postoperative pain management remains challenging. Despite the enhanced recovery after surgery (ERAS) protocol, regional analgesic techniques like modified perichondral approach to thoracoabdominal nerve block (M-TAPA) show promise. Our retrospective study evaluates M-TAPA's efficacy in postoperative pain control for laparoscopic cholecystectomy in a middle-income country.

Viral Hepatitis in Pregnant Mexican Women: Its Impact in Mother-Child Binomial Health and the Strategies for Its Eradication.

Viral hepatitis is the main cause of infectious liver disease. During pregnancy, a risk of vertical transmission exists both during gestation and at birth. HAV, HBV, and HCV might progress similarly in pregnant and non-pregnant women.

Influence of Maternal and Neonatal Factors on Transplacental Passive Immunity after Vaccination against COVID-19.

In the present study, we evaluated the influence of maternal and neonatal factors on the efficiency of the placental transfer of neutralizing antibodies against SARS-CoV-2. Vaccination during pregnancy provides fetal and neonatal protection through the passive transplacental transfer of maternal neutralizing antibodies. To date, little information is available regarding the factors that affect the transfer of antibodies against SARS-CoV-2.

Auditory Noise Facilitates Lower Visual Reaction Times in Humans.

Noise is commonly seen as a disturbance but can influence any system it interacts with. This influence may not always be desirable, but sometimes it can improve the system's performance. For example, stochastic resonance is a phenomenon where adding the right amount of noise to a weak signal makes it easier to detect.

Understanding factors limiting hematopoietic cell transplantation for acute myeloid leukemia patients in Mexico: a comprehensive analysis.

Acute myeloid leukemia (AML) is the most frequent indication for allogeneic hematopoietic cell transplantation (alloHCT) worldwide; social and health system barriers limit its access. We performed an observational retrospective analysis in Mexico to analyze factors limiting alloHCT in fit patients with AML. With a median follow-up of 11.

Endoscopic Characterization of Giant Choledocholithiasis and Its Correlation With Primary Choledocholithiasis.

Introduction: Gallstone disease is extremely prevalent in Western society, and the prevalence of common bile duct (CBD) stones with concomitant cholelithiasis increases significantly in the elderly. Different variants influence the treatment of this pathological entity, such as the origin of the stones, their location and quantity, comorbidities of the patient, impaction, and size of the lithos, the latter being an independent predictive factor. In most situations, choledocholithiasis can be resolved with endoscopic retrograde cholangiopancreatography (ERCP); however, in complex cases, such as giant choledocholithiasis (GC), advanced surgical, endoscopic, and percutaneous techniques are required to remove gallstones.

Post-pulmonary embolism syndrome: A reminder for clinicians.

Acute pulmonary embolism (APE) is one of the leading causes of cardiovascular emergencies and the third leading cause of death. Although efforts focus on treating the acute event, patients who survive APE may develop long-term sequelae. Research reveals that approximately half of patients who have suffered an APE do not regain their previous level of function and experience a reduction in their quality of life for several years after the episode.

Blockade of Ca3 calcium channels and induction of G/G cell cycle arrest in colon cancer cells by gossypol.

Background And Purpose: Gastrointestinal tumours overexpress voltage-gated calcium (Ca3) channels (Ca3.1, 3.2 and 3.

Pancreas transplantation: review.

Pancreas transplant (PTx) is the only treatment that establishes normal glucose levels for patients diagnosed with diabetes types 1 and 2. The paper aims to review and analyze graft survival, patient survival, and the impact on diabetic complications. We describe that the graft survival was 82-98% at 1 year, 90% at 5 years, and 75-54% at 10 years for simultaneous pancreas-kidney recipient; 71% pancreas after kidney (PAK), and 62% PTx alone at 1 year.

Clinical and Biochemical Characteristics of Hemophagocytic Lymphohistiocytosis in People Living With HIV and Disseminated Histoplasmosis at a Tertiary Hospital in Mexico.

Background: Hemophagocytic lymphohistiocytosis (HLH) is considered a rare disease with high morbidity and mortality risks. Most research on this disease is conducted in pediatric settings. Therefore, this study aimed to describe the clinical characteristics, laboratory findings, and outcomes related to HLH in people living with human immunodeficiency virus (HIV)/AIDS) and disseminated histoplasmosis.

Classification Criteria for Axial Disease in Youth With Juvenile Spondyloarthritis.

Objective: The goal was to develop and validate classification criteria for axial juvenile spondyloarthritis (SpA; AxJSpA).

Methods: This international initiative consisted of four phases: (1) item generation, (2) item reduction, (3) criteria development, and (4) validation of the AxJSpA criteria by an independent team of experts in an internationally representative validation cohort.

Results: These criteria are intended to be used on youth with a physician diagnosis of juvenile SpA and for whom axial disease is suspected.
