Cholelithiasis, Gut Microbiota and Bile Acids after Bariatric Surgery-Can Cholelithiasis Be Prevented by Modulating the Microbiota? A Literature Review.

Background: Cholelithiasis is one of the more common complications following bariatric surgery. This may be related to the rapid weight loss during this period, although the exact mechanism of gallstone formation after bariatric surgery has not been fully elucidated.

Methods: The present literature review focuses on risk factors, prevention options and the impact of the gut microbiota on the development of gallbladder stones after bariatric surgery.

Effects of Bioactive Dietary Components on Changes in Lipid and Liver Parameters in Women after Bariatric Surgery and Procedures.

Excess adipose tissue, as well as its distribution, correlates strongly with disorders of lipid and liver parameters and chronic inflammation. The pathophysiology of metabolic diseases caused by obesity is associated with the dysfunction of visceral adipose tissue. Effective and alternative interventions such as the Bioenteric Intragastric Balloon and bariatric surgeries such as the Roux-en-Y gastric bypass.

Rotational Thromboelastometry (ROTEM) in Relation to Inflammatory Biomarkers and Clinical Outcome in COVID-19 Patients.

The pathogenesis of hypercoagulability in COVID-19 patients is complex and not fully understood. Rotational thromboelastometry (ROTEM) is a viscoelastic method that allows the definition of a patient's hemostatic profile. This study aimed to assess the relationship between ROTEM parameters, the profile of inflammatory cytokines, and clinical outcomes in COVID-19 patients.

Impact of the Frequency and Type of Procedures Performed in Nuclear Medicine Units on the Expected Radiological Hazard.

Nuclear medicine procedures play an important role in medical diagnostics and therapy. They are related to the use of ionizing radiation, which affects the radiological exposure of all of the persons involved in their performance. The goal of the study was to estimate the doses associated with the performance of various nuclear medicine procedures in order to optimize workload management.

Application of collagen matrix in the prevention of anastomotic leaks following D2 gastrectomy with Roux-en-Y anastomosis.

Esophagoenteral anastomotic leaks are one of the most serious complications of gastric cancer surgeries. Leaking anastomosis has a negative impact on patient's prognosis as it translates into increased reoperation rates, direct and indirect mortality, as well as increased risk of cancer recurrence. Literature contains reports on the use of additional measures aimed at preventing anastomotic leaks.
