Introduction; p to 300 million people have the body mass index (BMI) greater than 30 kg/m2. Obesity is the cause of many serious diseases, such as type 2 diabetes, hypertension, and non-alcoholic fatty liver disease (NAFLD). Bariatric surgery is the only effective method of achieving weight loss in patients with morbid obesity., Objectives: The aim of the study was to assess the impact of bariatric surgery on non-alcoholic fatty liver disease in patients operated on due to morbid obesity., Material and Methods: We included 20 patients who were qualified for bariatric procedures based on BMI > 40 kg/ m2 or BMI > 35kg/m2 with the presence of comorbidities. The average body weight in the group was 143.85kg, with an average BMI of 49.16kg/m2. Before the procedure, we evaluated the severity of non-alcoholic fatty liver disease in each patient using the Sheriff-Saadeh ultrasound scale. We also evaluated the levels of liver enzymes. Follow-up evaluation was performed twelve months after surgery., Results: Twelve months after surgery, the average weight was 102.34 kg. The mean %WL was 33.01%, %EWL was 58.8%, and %EBMIL was 61.37%. All patients showed remission of fatty liver disease. Liver damage, evaluated with ultrasound imaging, decreased from an average of 1.85 on the Sheriff-Saadeh scale, before surgery, to 0.15 twelve months after surgery (p < 0.001). As regards liver enzymes, the level of alanine aminotransferase decreased from 64.5 (U/l) to 27.95 (U/l) (p < 0.001), and the level of aspartate aminotransferase decreased from 54.4 (U/l) to 27.2 (U/l)., Conclusions: Bariatric procedures not only lead to a significant and lasting weight loss, but they also contribute to the reduction of fatty liver disease and improve liver function.

Aim of the Study: The aim of this study was to evaluate the influence of laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric by-pass on risk factors of cardiovascular diseases., Material and Methods: We analyzed prospectively collected data of patients operated for morbid obesity who were qualified for laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric by-pass (LRYGB). Risk factors for wyłączecardiovascular diseases were assessed with the SCORE scale and both full and hard Framingham cardiovascular risk scores (FCRs). The data were collected on admission and one year after the procedures. We enrolled 264 patients (119 females, 116 males, 40.2±9.9 years old), of whom 117 underwent LRYGB and 118 LSG, respectively., Results: Preoperatively, 12% of patients were in the high-risk category of the SCORE scale, 65% were in the moderate risk category, and 24% were in the low-risk category. The median score of the SCORE scale was 1 (1-2). Lipid-based full FCR was 34.5% (24%-68%) and the hard FCR was 17.5% (10%-52%), while the respective BMI-based FCRs were 59% (31%-84%) and 37% (15%-67%). One year after the procedures, the mean %EBMIL (62.88%±20.02%) and %EWL (53.18%±15.87) were comparable between both procedures. Hypertension treatment was not necessary in 33 patients after LSG and in 55 after LRYGB. Diabetes mellitus remitted in 9 and 29 patients, respectively. Both procedures significantly reduced high and moderate risk prevalence in the SCORE scale in favor of the low risk category. Surgical interventions resulted in significant reductions of FCRs 1 year after surgery ( p<0.001)., Conclusions: Both LSG and LRYGB lead to a significant and comparable body mass reduction. Both procedures significantly decrease of the risk of cardiovascular diseases, based on SCORE and Framingham scales.

Introduction: e aim of the study was to evaluate the usefulness of Identification of Seniors at Risk (ISAR) scale among elderly patients admitted to the department of internal medicine., Material and Methods: The ISAR score was performed among patients aged >59 years a er admission to the hospital ward. Data from medical history about diseases, taken medicines, falls, length of hospital stay and mortality were compared in patients with ISAR score of 0-1 and over 1 and in subjects with and without history of falls. Regression analysis was used to detect predictors of the length of hospital stay or death., Results: The sample consisted of 102 subjects aged 80.9 ± 7.9 years, 45.5% of men, 34.6% had history of falls. The number of diseases was 11.3 ± 3.9 and number of medicines - 8.9 ± 3.7. The score of ISAR ≥2 was found in 90.2% of patients, length of hospital stay was 10.3 ± 8.4 days, mortality rate was 9.9%. Patients with ISAR score <2 were younger, showed a smaller number of diseases, used less drugs and had less frequency of falls than those with score ≥2. Patients with history of falls had higher mean ISAR score, higher number of diseases and medicines than the others. The increased number of diseases and higher ISAR score significantly influenced the length of hospital stay. None of the analyzed factors had any impact on mortality., Conclusion: The score of ISAR scale together with number of diseases have a positive impact on the length of hospital stay.
