Background: Femoroacetabular impingement (FAI) is a condition caused by abnormal contact between the femur head and the acetabulum, which damages the labrum and articular cartilage. While the prevalence and the type of impingement may vary across human groups, the variability among populations with short height or with a high prevalence of overweight has not yet been explored. Latin American studies have rarely been conducted in reference to this condition, including the Mayan and mestizo populations from the Yucatan Peninsula.

Patients with severe eosinophilic asthma (SEA) can benefit from biologic therapy but some subjects may present an immune-mediated side effect. These patients will not meet the treatment goals and might have an increased risk of exacerbations. Monitoring these patients by determining blood eosinophil (BE) levels could be one of the tools that may allow a follow-up to prevent a worsening of asthma or exacerbations.

Primary ciliary dyskinesia (PCD) is a rare lung disease that causes chronic oto-sino-pulmonary disease with irreversible lung damage. Several diagnostic methods exist, but electron microscopy (EM) is the most accurate tool, as it visualizes alterations in the axonemal ultrastructure; however, some patients may present a normal ciliary structure. Therefore, other diagnostic methods have been promoted, such as genetic studies or immunofluorescence of specific markers; nonetheless, they are not very accessible and expensive and even present a high level of false negatives.

The long-term effects of COVID-19 on lung function are not understood, especially for periods extending beyond 1 year after infection. This observational, longitudinal study investigated lung function in Mexican Hispanics who experienced severe COVID-19, focusing on how the length of recovery affects lung function improvements. At a specialized COVID-19 follow-up clinic in Yucatan, Mexico, lung function and symptoms were assessed in patients who had recovered from severe COVID-19.

Differences of sex development (DSDs) are a heterogeneous group of congenital conditions in which chromosomal, gonadal, or anatomical sex does not match. The broad spectrum of phenotypes associated with DSDs requires accurate diagnosis, which influences the care and quality of life of affected patients. The decreasing costs of next-generation sequencing (NGS) and international research collaborations in rare diseases have allowed the identification of new genes associated with DSDs.

Plant-based proteins: clinical and technological importance.

Food Sci Biotechnol

August 2024

Departamento de Nutrición Animal y Bioquímica, Facultad de Medicina Veterinaria y Zootecnia (FMVZ), Universidad Nacional Autónoma de México, Mexico City, Mexico.

Healthy and sustainable diets have seen a surge in popularity in recent years, driven by a desire to consume foods that not only help health but also have a favorable influence on the environment, such as plant-based proteins. This has created controversy because plant-based proteins may not always contain all the amino acids required by the organism. However, protein extraction methods have been developed due to technological advancements to boost their nutritional worth.

  • Urachal abnormalities are rare conditions caused by the incomplete closure of the urachal canal, leading to a persistent fibrous structure.
  • The diagnosis can begin with ultrasound but is typically confirmed through computed tomography (CT).
  • Surgical excision is the recommended treatment to alleviate symptoms and prevent recurrence, as demonstrated by a 45-year-old man who had recurrent urinary tract infections and underwent laparoscopic surgery.

The sternoclavicular joint dislocation is a very infrequent injury that can put the patient's life at risk if it is not diagnosed and treated properly. This can present as an anterior or posterior dislocation, the latter being less common and more dangerous due to its proximity to visceral structures of the thoracic cavity. Herein, we present the case of a 19-year-old male athlete diagnosed with a posterior dislocation of the right sternoclavicular joint due to indirect trauma during a soccer match, who was successfully treated with a figure-of-eight cerclage with high-resistance sutures plus an InternalBrace technique.

The post-nutritional intervention modulation of miRNA expression has been previously investigated; however, post-acute dietary-ingestion-related miRNA expression dynamics in individuals with obesity and insulin resistance (IR) are unknown. We aimed to determine the acute effects of protein ingestion from different dietary sources on the postprandial metabolic response, amino acid levels, and circulating miRNA expression in adults with obesity and IR. This clinical trial included adults with obesity and IR who consumed (1) animal-source protein (AP; calcium caseinate) or (2) vegetable-source protein (VP; soy protein isolate).

  • An 80-year-old man with a history of heart issues presented with shortness of breath, revealing decreased heart sounds and irregular rhythms during the exam.
  • Advanced imaging techniques showed pericardial calcification, leading to a diagnosis of constrictive pericarditis, likely idiopathic but possibly related to his previous heart conditions.
  • While surgery (pericardiectomy) is an option for severe symptoms, doctors should also consider the patient's preferences for less invasive treatments, including rehabilitation strategies for managing symptoms.
