Post-COVID-19 Syndrome: Audiometric Findings in Patients with Audiological Symptoms.

Since the SARS-CoV-19 pandemic, the possibility of audiological involvement by this virus has been speculated without being able to generate a true cause-effect relationship. The objective of this observational, descriptive cross-sectional study is to describe the audiometric findings of post-COVID-19 patients with audiological symptoms. A sample of 47 patients with a diagnosis of COVID-19 infection was included: The age range was between 18 and 50 years old, the mean age was 37.

Risk Factors for Mortality of Hospitalized Adult Patients with COVID-19 Pneumonia: A Two-Year Cohort Study in a Private Tertiary Care Center in Mexico.

During the COVID-19 pandemic, the high prevalence of comorbidities and the disparities between the public and private health subsystems in Mexico substantially contributed to the severe impact of the disease. The objective of this study was to evaluate and compare the risk factors at admission for in-hospital mortality of patients with COVID-19. A 2-year retrospective cohort study of hospitalized adult patients with COVID-19 pneumonia was conducted at a private tertiary care center.

Cultural Sensitivity and Global Pharmacy Engagement in Latin America: Argentina, Brazil, Ecuador, Guatemala, and Mexico.

To establish and maintain successful global pharmaceutical and health care partnerships, pharmacists, pharmacy educators, and students should first learn more about the political, cultural, economic and health care dynamics that affect all of the parties involved in these arrangements. This paper explores Latin America within the context of transnational pharmacy and health-based engagement, including pharmacy-related concepts, health care and cultural considerations, behavioral health perspectives, and common misconceptions. Expert knowledge and experience were used to support and corroborate the existing literature about cultural dynamics of health.

Angiocentric Centrofacial Lymphoma as a Challenging Diagnosis in an Elderly Man.

BACKGROUND Angiocentric centrofacial lymphomas, now known as nasal-type extranodal natural killer T-cell lymphomas, are neoplasms of highly destructive characteristics that mainly affect the nasal cavity and palate. The most frequent clinical presentation includes fever, weight loss, nasal obstruction, epistaxis, nasal or facial edema, as well as necrotic ulcers in the nasal cavity, gums, and palate. It has been found to have an important association with the Epstein-Barr virus.

A 60 kDa prolactin variant secreted by cervical cancer cells modulates apoptosis and cytokine production.

Prolactin (PRL) is associated with different types of cancer, such as cervical cancer. Recombinant PRL has antiapoptotic effect on cervical cancer cells, and it can also induce cytokine production on macrophages. A 60 kDa variant of PRL is produced by cervical cancer cells.

Increased expression of the prolactin receptor is associated with malignant laryngeal tumors.

The altered expression of the prolactin receptor (PRLR) has been associated with the development of various types of cancer, particularly breast, prostate and endometrial cancer. However, in laryngeal tumors, the expression of PRLR has not yet been documented. The aim of this study was to determine the expression and localization of PRLR in laryngeal cancer (LC) in comparison with recurrent respiratory papillomatosis (RRP).
