Background: SARS-CoV-2 virus was notified by the World Health Organization in January 2020 as a global emergency, due to its intense transmission, and clinical picture, that is aggravated in susceptible people.
Objective: To describe the factors associated with death in COVID-19 and pneumonia patients hospitalized in a thirdlevel center.
Material And Methods: An undivided case-control study was carried out.
Article Synopsis
- The study investigates whether blood groups (BG) influence susceptibility to SARS-CoV-2 infection among healthcare workers prior to vaccination.
- Using a cross-sectional design, researchers compared the blood groups, antibody presence, and symptoms of 102 convalescent health workers against 116 controls from March to June 2020.
- Results indicated that blood group O was the most common among both groups, with a non-significant lower risk of infection associated with BG-O and a potential higher risk for BG-A, while 15% of the convalescent group did not develop antibodies post-infection.
Introduction: Mesenchymal tumors of the gastrointestinal tract are a group spindle cell tumors which include gastrointestinal stromal tumors, leiomyomas, leiomyosarcomas and schwannomas (Nishida and Hirota, 2000). Schwannomas generally present as a slow and asymptomatic growing mass in the gastrointestinal tract typically arising in the gastric submucosa accounting for up to 0.2% of gastric tumors (Melvin and Wilkinson, 1993; Sarlomo-Rikala M, Miettinen, 1995).

Aim: Calculate the Relative Risk of associated factors to surgical site infections in adult with elective surgery.
Methods: Patients were classified according to the surgery contamination degree; patient with surgery clean was defined as no exposed and patient with clean-contaminated or contaminated surgery was defined exposed.
The thyroid descends through the foramen cecum leaving the thyroglossal duct, which disappears between the fifth and the tenth week of pregnancy. The lack of involution of any part of this duct results in thyroglossal cyst formation. Its diagnostic approach is made by cervical ultrasound, computed tomography and magnetic resonance imaging.

- The study focused on the complications associated with gallbladder and biliary tract surgery in elderly patients over 60 years old.
- A total of 236 patients were analyzed, with most undergoing laparoscopic cholecystectomy, and the results showed that complications were generally low and associated more with emergency surgeries.
- The findings suggest that age does not significantly increase surgical risk, indicating that laparoscopic procedures can be safely performed on geriatric patients.
Background: 99mTc sestamibi scanning and aspiration biopsy can predict the histopathological result of a thyroid nodule fairly accurately.
Objective: To determine the accuracy of 99mTc sestamibi scanning in detecting malignancy in patients with thyroid nodule confirmed by definitive histopathological report after thyroidectomy.
Material And Methods: A total of 69 patients with a solitary thyroid nodule were studied.
Background: Severe acute pancreatitis has a reported mortality of 10-30% in specialized hospitals, representing 20% of patients diagnosed with acute pancreatitis. Indications for surgery are infected necrosis, necrosis persistent, fulminant pancreatitis or acute pancreatitis complications such as bleeding or intestinal perforation.
Methods: We studied patients diagnosed with pancreatitis from January 1, 2000 to December 31, 2007.
