RESUMEN
Introduction: Although COVID-19 is not currently a public health emergency, it will affect susceptible individuals in the post-COVID-19 era. Hence, the present study aimed to develop a model for Iranian patients to identify at-risk groups based on past medical history (PMHx) and some other factors affecting the death of patients hospitalized with COVID-19. Methods: A secondary study was conducted with the existing data of hospitalized COVID-19 adult patients in the hospitals covered by Iran University of Medical Sciences. PMHx was extracted from the registered ICD-10 codes. Stepwise logistic regression was used to predict mortality by PMHx and background covariates such as intensive care unit (ICU) admission. Crude population attributable fraction (PAF) as well as crude and adjusted odds ratio (OR) with 95% confidence interval (CI) were reported. Results: A total of 8879 patients were selected with 19.68% mortality. Infectious and parasitic diseases' history showed the greatest association (OR = 5.72, 95% CI: 4.20, 7.82), while the greatest PAF was for cardiovascular system diseases (20.46%). According to logistic regression modeling, the largest effect, other than ICU admission and age, was for history of infectious and parasitic diseases (OR = 3.089, 95% CI: 2.13, 4.47). A good performance was achieved (area under curve = 0.875). Conclusion: Considering the prevalence of underlying diseases, many mortality cases of COVID-19 are attributable to the history of cardiovascular disease. Future studies are needed for policy making regarding reduction of COVID-19 mortality in susceptible groups in the post-COVID-19 era.
RESUMEN
BACKGROUND: Obesity is a main risk factor for type 2 diabetes. Bariatric surgery can help diabetic patients with obesity. Among different types of metabolic surgeries, one anastomosis gastric bypass (OAGB) surgery is a new procedure. AIM: To comprehensively determine the diagnostic values of advanced-diabetic remission (Ad-DiaRem), one of the scoring systems, in predicting diabetic remission after OAGB surgery. METHODS: In this retrospective cohort study, patients aged 18-60 years with type 2 diabetes and obesity, who had undergone OAGB surgery, were included. Diagnostic values of Ad-DiaRem on diabetes remission, after OAGB surgery, which consist of sensitivity (Sen), specificity (Spe), positive and negative predictive values (P/NPV), positive and negative likelihood ratios (P/NLR), accuracy, and odd ratio (OR), were determined. RESULTS: The percentages of complete diabetic remission after surgery were 56.3% and 53.8% in 12th and 24th months, respectively. The remission cut-off point for Ad-DiaRem was defined 10 considering the highest Youden's index. Among the evaluation indices, the values of Spe, PPV, accuracy, and OR were assigned a high value in both 12th and 24th months of follow-up; however, the area under curve (AUC) was 20% in both. CONCLUSION: According to our findings, the model of diagnostic values of Ad-DiaRem for predicting diabetic remission should be specified according to race, place of residence, and prevalence of diabetes in society. Presently, this model can be used cautiously until a new model is proposed by further studies.

PURPOSE: Although bariatric surgery is associated with a decrease in obesity complications, it may affect the children's growth by a maternal nutritional deficiency. This study was conducted to assess the effect of maternal bariatric surgery on offspring anthropometry. MATERIALS AND METHODS: In a mixed cohort, anthropometric status of children aged 5 years or less born to mothers with a history of bariatric surgery was compared with a control group consists of peers born to mothers with obesity but without bariatric surgery. Anthropometric indices including crude and quantile values for BMI, weight, height, and head circumference at birth and the first 5 years of life were measured. Then, the adjusted effect of maternal surgical history on anthropometric status was estimated by linear regression. RESULTS: From a total of 56 children, 28 born to mothers with a history of bariatric surgery, and 28 born to mothers with obesity but without bariatric surgery. At birth, weight (2915 vs 3225 g) and BMI (11.72 vs 12.94 kg/m2) were lower in the group with maternal bariatric surgery than in the control group (P = 0.02 and P = 0.03, respectively), although after regression adjustment, there was only a significant difference between the two groups in height for age value in children less than 5 years old (B = 0.872, P-value = 0.001). CONCLUSION: Bariatric surgery with decrease of weight indices at birth has a probable influence on growth and development in next years. Therefore, it is recommended further studies to identify unknown effect of types of preconception surgical procedures on childhood outcomes.

BACKGROUND: Small bowel length (SBL) may have an impact on the outcomes of bariatric surgeries, but it can be difficult to make a direct association between SBL and the safety and outcome of bariatric surgeries. OBJECTIVES: To address this issue, we set out to devise a predictive model for SBL determination based on clinical and anthropometric variables. SETTING: An academic tertiary medical center. METHODS: Anthropometric and clinical data, including age, sex, height, weight, and past medical history, were collected upon enrollment. SBL was measured twice during the surgery using a marked grasper. In all cases, measurements were carried out by a single surgeon. To create a predictive model, a 2-step approach was employed. In the first step, linear regression was used to determine influential variables. In the second step, all variables with a P value < .2 were entered into a multivariate regression model. RESULTS: Overall, 961 bariatric candidates were enrolled. The mean age of the participants was 40.08 years, and 77.5% (n = 745) were female. The mean SBL was 748.90 centimeters. There was a weak but statistically significant positive correlation between SBL with both weight and height. Our univariate linear model determined only anthropometric parameters as a predictor of SBL. The multivariate model also yielded that none of the entered parameters were shown to be accurate predictors of SBL. Moreover, only 4.3% of variances were explainable by this model. CONCLUSION: Although we found a weak positive association between height and SBL, this association lacked clinical practicality.

Background: Obesity and Helicobacter pylori (H. pylori) infection are public health problems in the world and Iran. This study aimed to indicate the anatomical place with the most accurate results for H. pylori. According to gastric mapping, this study will be able to evaluate the prevalence of H. pylori based on the pathology of gastric mapping and the accuracy of the antral rapid urease test (RUT) based on endoscopic findings. Methods: In this cross-sectional study, upper digestive endoscopy and gastric pathology were studied in 196 obese patients candidates for bariatric surgery. Statistical analyses were performed using a t-test and Chi-square/fisher's exact test to compare the groups. Sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), negative likelihood ratio (NLR), and odds ratio (OR) were used to compare RUT and pathological H. pylori test of each of the six areas of the stomach. We set a positive test of the pathology of 6 regions of the stomach as our gold standard (in this study). Results: The most common area of the stomach for pathological findings of H. pylori were incisura (116, 59.2%), greater curvature of the antrum (115, 58.3%), lesser curvature of the antrum (113, 57.7%), lesser curvature of the corpus (112, 57.1%), greater curvature of the corpus (111, 56.6%) and cardia (103, 52.6%). The prevalence of H. pylori was 58.2% (114 cases) and 61.2% (120 cases) with RUT and gastric pathology, respectively. Mild, moderate, and severe infection of H. pylori in cardia (58, 29.6%), greater and lesser curvature of the antrum (61, 31.1%), and greater curvature of the antrum (37, 18.9%) had the highest percentages of incidence comparing to other sites of the stomach, respectively. The most sensitive area for pathologic biopsy was incisura (96.6%, 95% confidence interval: 91.7, 98.7). Conclusion: According to the highest sensitivity, PLR, NPV, and pathological findings of H. pylori in accordance with the lowest NLR in the incisura compared with other parts of the stomach, it is highly recommended to take the biopsy from the incisura instead of other anatomical places of stomach for detecting H. pylori specifically if our strategy is taking only one biopsy.
RESUMEN
Background: Due to the changing conditions of education, research, and treatment in the world, especially the recent pandemic, and more use of virtual space, there is a need for evaluation of digital professionalism in faculty members as the most influential people who have a direct and deep impact on the next generation. Methods: In this analytical cross-sectional study that was conducted in 2023 on 149 faculty members of Iran University of Medical Sciences, they were invited to participate in the study through various methods (SMS, E-mail, and media messages). The link to the Persian standardized questionnaire was made available for participants. If a person received less than 70% of the score in each area, he/she would receive solutions to improve his/her situation in that area at the end of answering the questions. The self-administered questionnaire has 5 fields and 33 questions. Maximum scores were 10 points. Spearman and Pearson correlation coefficients and statistical tests consisting of chi-square, t-test, Mann-Whitney U, one-way ANOVA, and Kruskal-Wallis H were used in the analysis. Results: The mean overall score of people in principles of digital professionalism was 0.8. Women and basic sciences faculties had a significantly better status than men and clinical faculties in the principles of digital professionalism as a whole (P = 0.001 and P = 0.049, respectively). The domain of "knowledge management and information literacy" had significantly lower scores in professors in comparison with other degree (instructors, assistant professors, and associate professors (P = 0.039). Conclusion: The mean score of the principles of digital professionalism is acceptable at 80%. Coherent, timely, and up-to-date training to ensure the effective, safe and appropriate use of digital technology, especially for men, professors and clinical faculty members who had a lower score than others, should be done.
RESUMEN
BACKGROUND: Being obese can lead to various complications during pregnancy, such as Gestational Diabetes Mellitus (GDM), pregnancy induced hypertension (PIH), Pre-Eclampsia (PE), and Large Gestational Age (LGA). Although bariatric surgery is an effective way to treat obesity, it can also result in complications and may be linked to having small for gestational age (SGA) babies. This cohort study protocol aims to compare the maternal and fetal/neonatal outcomes of two groups of Iranian pregnant women: those who have undergone bariatric surgery and those who are obese but have not had bariatric surgery. METHODS: In this study Pregnant women (< 14 weeks' gestation) (n = 38 per group) are recruited either from one of the obesity clinic (exposure group = with a history of bariatric surgery) or primary healthcare clinics in Tehran city (comparison group = pregnant women with obesity and and no history of bariatric surgery). Dietary intake and nutrient status are assessed at < 14, 28, and 36 weeks. Maternal and fetal/neonatal outcomes are compared between the two groups, including gestational diabetes, preeclampsia, preterm labor, intrauterine growth restriction, severe nausea and vomiting, abortion, placenta previa and abruption, venous thrombosis, vaginal bleeding, cesarean delivery, meconium aspiration, and respiratory distress. Maternal serum levels of ferritin, albumin, zinc, calcium, magnesium, selenium, copper, vitamins A, B9, B12, and 25-hydroxy Vit D are checked during 24th to 28th weeks. Maternal and neonatal outcomes, including height, weight, head circumference, fetal abnormality, infection, small or large fetus, low birth weight, macrosomia, NICU admission, and total weight gain during pregnancy, are measured at birth. Maternal and offspring outcomes, including weight, height, head circumference, total weight gain during pregnancy, newborn diseases, postpartum bleeding, breastfeeding, and related problems, are assessed 6 weeks after delivery. Child's weight, height, and head circumference are followed at 2, 4, 6, 8, 10, and 12 months after birth. Maternal stress, anxiety, and depression are assessed with the DASS-21 questionnaire, and physical activity is evaluated using the PPAQ questionnaire in the first and third trimesters. DISCUSSION: By assessing the levels of micronutrients in the blood of pregnant women along with the evaluation of pregnancy outcomes, it is feasible to gain a more accurate understanding of how bariatric surgery affects the health and potential complications for both the mother and the fetus/newborn. This information can help specialists and patients make more informed decisions about the surgery. Additionally, by examining issues such as stress, anxiety, and depression in women undergoing surgery, this study can contribute to recognizing these problems, which can also affect pregnancy outcomes.

Bariatric surgery (BS) has been as a currently developed treatment of choice for metabolic syndrome (MetS). Which, in turn, is well-known as serious public health concern. Therefore, this study assessed the outcomes of different procedures of BS and possible predictors for improving MetS. This single-center retrospective cohort analysis included bariatric candidates between 2009 and 2017. The operational approach was chosen based on the patient's condition, as well as the patient's metabolic profile and the surgeon's experience. All desired information was evaluated at baseline and 6, 12, and 24 months after the operation. Of the 1111 patients included, 918 (82.6%) were female. There was no considerable trend in the improvement of MetS over the follow-up period of each surgery group. After 6 to 24 months of follow-up, waist circumference reduction was significant in all three types of surgery, and sleeve gastrectomy resulted in the best (but not significant) improvement rates after 24 months (P = 0.079). One anastomosis gastric bypass had highest decrease in percentage of excess weight loss than other procedures (P < 0.001). Each year increase in age was associated with a 4% decrease in MetS remission. In addition, the male gender, was correlated with MetS improvement positively (P = 0.049). Each one-unit increase in hemoglobin A1c (HbA1c) reduced the MetS remission rate by 40%. All three methods of BS were similarly effective in MetS. Consider the predictive value of age, gender, and HbA1c before determining the optimum procedure for each patient is recommended.

INTRODUCTION: This review aims to investigate the gastroesophageal reflux disease (GERD) as one of the important concerns for both surgeons and patients after one anastomosis gastric bypass (OAGB). METHOD: PubMed, Scopus, Embase, Web of Science, and Cochrane were reviewed by the end of the 2021 with keywords relating to GERD, OAGB, and their equivalents. Data regarding OAGB, number of patients with GERD, treatment for GERD, endoscopy findings, the interval between GERD and OAGB were retrieved by two independent investigators. The primary effect/effect size measure was prevalence. RESULTS: 40 studies examining 17,299 patients were included revealing that 2% of patients experience GERD following OAGB. Reflux after revisional OAGB is six times higher than primary OAGB. Despite being unclear, medical and surgical treatments for GERD after OAGB were used in 60% and 41% of patients with estimated success rate of 85% and 100%, respectively. CONCLUSION: Based on how GERD was identified after OAGB, its rate ranged from 0 to 55%; the pooled rate of 2% is near to Roux-en-Y gastric bypass. GERD symptoms can be mild to be tolerated without medical treatment, moderate that respond to acid-reducing agents, or severe enough that are categorized as interactable and would need a surgical intervention.

PURPOSE: Using a single percentile chart provides us with high standards for the evaluation and accurate investigation of sufficient weight loss after bariatric surgery, counseling, and treating patients in an evidence-based way. Creating percentile charts of weight loss for gastric bypass is the aim of this study. MATERIALS AND METHODS: This retrospective study was based on data from patients who underwent RYGB or OAGB from February 2008 to February 2020. The lambda-mu-sigma (LMS) method was used to estimate the reduction in body mass index (BMI) and six other metrics measured throughout post-operative follow-up. Percentile charts for various metrics have been presented for the first 2 years' post-surgery. We applied a bootstrap sampling method to evaluate percentile validity. RESULTS: We recruited 2579 and 1943 patients who underwent OAGB (75% female) and RYGB (84% female) and were between the ages of 18 and 70 years. The preoperative BMI of patients in the OAGB group was higher than in the RYGB group. Concerning RYGB weight reduction results, the maximum percentage of excess weight loss (%EWL) occurs 18 months after surgery and is steady at 24 months. Far above 50%, EWL is achieved after 6 months. OAGB weight loss follows the same trend as RYGB; at 6 months, the %EWL values are slightly higher than RYGB. CONCLUSIONS: We present the first bariatric weight loss percentile chart for OAGB. It allows evaluation of sufficient and insufficient weight loss at any post-operative point in a visual aspect. Furthermore, it predicts prospective outcomes and guides patient monitoring.

Introduction: The objective of this study is to investigate the interaction between Candida albicans and human proteins during oral candidiasis, with the aim of identifying pathways through which the pathogen subverts host cells. Methods: A comprehensive list of interactions between human proteins and C. albicans was obtained from the Human Protein Interaction Database using specific screening criteria. Then, the genes that exhibit differential expression during oral candidiasis in C. albicans were mapped with the list of human-Candida interactions to identify the corresponding host proteins. The identified host proteins were further compared with proteins specific to the tongue, resulting in a final list of 99 host proteins implicated in oral candidiasis. The interactions between host proteins and C. albicans proteins were analyzed using the STRING database, enabling the construction of protein-protein interaction networks. Similarly, the gene regulatory network of Candida proteins was reconstructed using data from the PathoYeastract and STRING databases. Core module proteins within the targeted host protein-protein interaction network were identified using ModuLand, a Cytoscape plugin. The expression levels of the core module proteins under diseased conditions were assessed using data from the GSE169278 dataset. To gain insights into the functional characteristics of both host and pathogen proteins, ontology analysis was conducted using Enrichr and YeastEnrichr, respectively. Result: The analysis revealed that three Candida proteins, HHT21, CYP5, and KAR2, interact with three core host proteins, namely, ING4 (in the DNMT1 module), SGTA, and TOR1A. These interactions potentially impair the immediate immune response of the host against the pathogen. Additionally, differential expression analysis of fungal proteins and their transcription factors in Candida-infected oral cell lines indicated that Rob1p, Tye7p, and Ume6p could be considered candidate transcription factors involved in instigating the pathogenesis of oral candidiasis during host infection. Conclusion: Our study provides a molecular map of the host-pathogen interaction during oral candidiasis, along with potential targets for designing regimens to overcome oral candidiasis, particularly in immunocompromised individuals.
RESUMEN
INTRODUCTION: Bariatric surgery may lead to unsatisfactory weight loss, weight loss plateau, and even weight regain after various types of surgery. Despite the numerous studies, the mid-term results of surgery, after repetitive weight fluctuations remain a major concern. The aim of the present study was to determine the key time points of weight changes after three types of bariatric procedures, as well as to determine 5-year weight loss outcome after surgery. METHODS: This is a retrospective cohort study including patients with morbid obesity conducted in the Minimally Invasive Surgery Research Center. The patients underwent one of the three types of bariatric surgeries including laparoscopic sleeve gastrectomy (LSG), Roux-en-Y gastric bypass (RYGB), and one-anastomosis gastric bypass (OAGB), who had been followed up for weight loss trend during 5 years postoperatively. RESULTS: The mean excessive weight loss (%EWL) and total weight loss (%TWL) of 2,567 participants with obesity (mean age = 39.03, mean BMI = 45.67) in the first 6 months after surgery was independent of the type of surgery (p > 0.05). OAGB and RYGB showed significantly higher weight loss compared to LSG in ninth and 24th month after surgery, respectively (p < 0.05). The 5 years %WL could be comparable with %WL in 6, 9, and 12 months after LSG, RYGB, and OAGB, respectively. CONCLUSION: OAGB provides the fastest and highest %EWL and %TWL, while LSG induced the earliest and largest weight plateau and weight regain during 5-years post-surgery. The pattern of early weight loss could predict the mid-term outcome of bariatric surgery. So, early identification of suboptimal weight loss could enhance long-term weight loss.

BACKGROUND: Besides impaired respiratory function and immune system, COVID-19 can affect renal function from elevated blood urea nitrogen (BUN) or serum creatinine (sCr) levels to acute kidney injury (AKI) and renal failure. This study aims to investigate the relationship between Cystatin C and other inflammatory factors with the consequences of COVID-19. METHODS: A total of 125 patients with confirmed Covid-19 pneumonia were recruited in this cross-sectional study from March 2021 to May 2022 at Firoozgar educational hospital in Tehran, Iran. Lymphopenia was an absolute lymphocyte count of less than 1.5 × 109/L. AKI was identified as elevated serum Cr concentration or reduced urine output. Pulmonary consequences were evaluated. Mortality was recorded in the hospital one and three months after discharge. The effect of baseline biochemical and inflammatory factors on odds of death was examined. SPSS, version 26, was used for all analyses. P-vale less than 0.05 was considered significant. RESULTS: The highest amount of co-morbidities was attributed to COPD (31%; n = 39), dyslipidemia and hypertension (27%; n = 34 for each) and diabetes (25%; n = 31). The mean baseline cystatin C level was 1.42 ± 0.93 mg/L, baseline creatinine was 1.38 ± 0.86 mg/L, and baseline NLR was 6.17 ± 4.50. Baseline cystatin C level had a direct and highly significant linear relationship with baseline creatinine level of patients (P < 0.001; r: 0.926). ). The average score of the severity of lung involvement was 31.42 ± 10.80. There is a direct and highly significant linear relationship between baseline cystatin C level and lung involvement severity score (r = 0.890, P < 0.001). Cystatin C has a higher diagnostic power in predicting the severity of lung involvement (B = 3.88 ± 1.74, p = 0.026). The mean baseline cystatin C level in patients with AKI was 2.41 ± 1.43 mg/L and significantly higher than patients without AKI (P > 0.001). 34.4% (n = 43) of patients expired in the hospital, and the mean baseline cystatin C level of this group of patients was 1.58 ± 0.90 mg/L which was significantly higher than other patients (1.35 ± 0.94 mg/L, P = 0.002). CONCLUSION: cystatin C and other inflammatory factors such as ferritin, LDH and CRP can help the physician predict the consequences of COVID-19. Timely diagnosis of these factors can help reduce the complications of COVID-19 and better treat this disease. More studies on the consequences of COVID-19 and knowing the related factors will help treat the disease as well as possible.

INTRODUCTION AND IMPORTANCE: Surgeons may mistakenly consider the right hepatic duct as cystic duct, ligate, and divide it. CASE PRESENTATION: A 58-year-old woman presented with right upper quadrant (RUQ) abdominal pain, nausea, and RUQ tenderness, but negative Murphy's sign. Common bile duct was 10 mm based on abdominal ultrasound. Common hepatic duct and intrahepatic ducts consist of multiple common bile duct (CBD) stones with sludge and multiple small gallstones. Different diagnostic procedures (Computed tomography (CT) scan, magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiopancreatography (ERCP)) showed the connection of the cystic duct to the right hepatic duct. Balloon sweeping for stones extraction and then laparoscopic cholecystectomy was successfully done. CLINICAL DISCUSSION: Radiologic evaluations like MRCP, CT scan, ERCP or sonography before or during the surgery/endoscopic interventions seem logical at least for selected patients. CONCLUSION: Before endoscopic/surgical interventions we need to be sure about the anatomy of biliary tree by a suitable para-clinic evaluation.
RESUMEN
Background and Aims: Venous thromboembolism (VTE) is the most common cause of death during the first 30 days after surgery. There is not any study which critically evaluated clinical guidelines related to VTE prophylaxis in urological surgeries. Therefore, in this study, we decided to evaluate related clinical guidelines using the AGREE II instrument to take a positive step towards improving the care of these patients. Methods: The latest version of all available clinical guidelines related to the topic of VTE prophylaxis in urological surgeries until 2021 was searched. Four appraisers, including one urologist, one cardiologist, one epidemiologist, and one MD who had prior knowledge of working with the AGREE II tool and international articles in this field appraised selected clinical guidelines. Using the AGREE II review tool, clinical guidelines were critically evaluated. Then, the score of six domains of AGREE II for each guideline was calculated and compared with each other, and the relationship between the domains was measured by Kendall's correlation test. To determine the reliability of the test, interclass correlation coefficients were calculated for all indicators. Results: Items were rated on a 7-point scale from 1 (strongly disagree) to 7 (strongly agree). NICE, CHEST, and EAU guidelines obtained the highest scores from the Overall Assessment criteria by scoring 6, 5.75, and 5.25, respectively. There was only a correlation between the score of Overall Assessment criterion with "Applicability" domain, with Kendall's correlation coefficient of 0.867 and p = 0.015. The domains of "Clarity and presentation" and "Scope and purpose" obtained the highest standardized scores by getting 84.49% and 75.69%, respectively, and "Applicability" with 30.04% obtained the lowest standardized score. Conclusion: In this study, NICE, CHEST, and EAU guidelines are suggested as clinical guidelines by obtaining the highest scores from Overall Assessment criterion.
RESUMEN
This trial was designed to evaluate the effect of a standardized capsule of Aloe vera gel (AVG) on the quality of life (QOL) in patients with systolic heart failure (HF). Forty-two patients were randomly divided into two groups to receive either AVG 150 mg or harmonized placebo capsules twice a day for 8 weeks. The patients were evaluated before and after the intervention using the Minnesota Living with Heart Failure Questionnaire (MLHFQ), New York Heart Association (NYHA) functional class, six-minute walk test (6MWT), Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI) and STOP-BANG questionnaires. Post-intervention, AVG group indicated a significant reduction in the total score of MLHFQ (p < 0.001). The changes in MLHFQ and NYHA class were statistically significant after taking medication (p < 0.001 and p = 0.004, respectively). The change of 6MWT in the AVG group was more advanced; however, it was not statistically significant (p = 0.353). Moreover, in the AVG group, the severity of insomnia and obstructive sleep apnea decreased (p < 0.001, p = 0.01 respectively) and the sleep quality improved as well (p < 0.001). There were significantly fewer adverse events reported in the AVG group (p = 0.047). Therefore, AVG combined with standard medical therapy could provide more clinical benefits for patients with systolic HF.

PURPOSE: Sleeve gastrectomy (SG) is the most common bariatric procedure worldwide. It has been reported that there is a strong association between SG and the development of gastroesophageal reflux disease (GERD) and Barrett's esophagus (BE). This study was conducted to evaluate esophagogastroduodenoscopy (EGD) findings in patients with a history of SG with more than 5-year follow-up. METHODS: This is a retrospective cohort study of prospectively maintained database. Inclusion criteria included patients who underwent SG between April 2015 and March 2016, aged 18 and above, BMI ≥ 40 kg/m2. Patients with 5 years of follow-up were invited to take part in the study and underwent EGD and biopsy. RESULTS: One hundred twenty-six patients were recruited with a mean age of 44.6 ± 11.1 years. After a 5-year follow-up, there were 31 (29.5%) patients with reflux esophagitis. The grades of GERD were A, B, and C in 16 (15.2), 12 (11.4), and 3 (2.9%) patients, respectively. Incidence of BE was 5.7% after 5 years from SG. There was a 16.6% lost to follow-up at 5 years after SG. CONCLUSION: The diagnosis and severity of GERD and the search for BE justify endoscopic surveillance in all long-term post-sleeve patients, regardless of reflux symptoms.

INTRODUCTION: It could be valuable for surgeons and patients to use one chart in different groups and evaluate weight loss during the post-surgery period. METHODS: This retrospective study used the Iran National Obesity Surgery Database. Patients with clinically severe obesity aged 18-70 undergoing sleeve gastrectomy participated in this study. Body mass index (BMI) reduction and 5 other metrics measured over the study period were modeled using lambda-mu-sigma method. Our data were split into the train (70%) and test (30%) sets. RESULTS: In this study, 1,258 patients (75% female) met the eligibility criteria to participate. Mean age and initial BMI were 36.87 ± 10.51 and 42.74 (40.37-46.36), respectively. Percentile charts for various metrics have been presented for the first 2 years after surgery. CONCLUSIONS: For sleeve surgery, all metrics are acceptable for clinical applications. Using the statistical view, BMI reduction is the most acceptable metric according to the lowest bias values and its variation between all the metrics.

BACKGROUND: Identifying breast cancer risk factors is a critical component of preventative strategies for this disease. This study aims to identify modifiable and non-modifiable risk factors of breast cancer in Iranian women. METHODS: We used international databases (PubMed/Medline, Scopus, Web of Knowledge, and Embase) and national databases (SID, Magiran, and ISC) to retrieve relevant studies until November 13, 2022. The odds ratio (OR) with a 95% confidence interval using the random-effect model was used to estimate the pooled effect. The publication bias was assessed by the Egger and Begg test. A sensitivity analysis was conducted to evaluate the effect of each included study on the final measurement. RESULTS: Of the 30,351 retrieved articles, 24 matched case-control records were included with 12,460 participants (5675 newly diagnosed cases of breast cancer and 6785 control). This meta-analysis showed that of the known modifiable risk factors for breast cancer, obesity (vs normal weight) had the highest risk (OR = 2.17, 95% CI 1.47 to 3.21; I2 = 85.7) followed by age at marriage (25-29 vs < 18 years old) (OR = 2.00, 95% CI 1.53 to 2.61; I2 = 0), second-hand smoking (OR = 1.86, 95% CI 1.58 to 2.19; I2 = 0), smoking (OR = 1.83, 95% CI 1.41 to 2.38; I2 = 18.9), abortion history (OR = 1.44, 95% CI 1.02 to 2.05; I2 = 66.3), oral contraceptive use (OR = 1.35, 95% CI 1.11 to 1.63; I2 = 74.1), age at marriage (18-24 vs < 18 years old) (OR: 1.22, 95% CI 1.02 to 1.47; I2 = 0). Of non-modifiable risk factors, history of radiation exposure (OR = 3.48, 95% CI 2.17 to 5.59; I2 = 0), family history of breast cancer (OR = 2.47, 95% CI 1.83 to 3.33; I2 = 73), and age at menarche (12-13 vs ≥ 14 years old) (OR = 1.67, 95% CI 1.31-2.13; I2 = 25.4) significantly increased the risk of breast cancer. CONCLUSIONS: Since most risk factors related to breast cancer incidence are modifiable, promoting healthy lifestyles can play an influential role in preventing breast cancer. In women with younger menarche age, a family history of breast cancer, or a history of radiation exposure, screening at short intervals is recommended.

Background: A large liver size is a factor that may increase the difficulty of bariatric surgery (BS) and unwanted complications. Some agents have been used to decrease the liver size before BS. Silymarin has been used as an antioxidant agent to improve liver function tests. This study was designed to evaluate the effects of silymarin on liver dimensions, function, and lipid profile. Materials and Methods: A double-blind randomized clinical trial was performed on 56 patients. The patients were divided into silymarin and placebo groups. Blood samples and sonographic examinations were taken from the patients before and 4 weeks after the administration of the silymarin or placebo. In the first group, 140 mg silymarin was prescribed every 8 h for 4 weeks, and the other group received placebo in the same way with the same tablet shape. After the completion of the 4-week treatment, laboratory tests and ultrasonography were carried out again. Results: Thirty-nine (69.6%) patients were female with a mean body mass index (BMI) of 46.2 kg/m2 and a mean age of 36.8 years. Most of the patients had a compliance of 80% and higher. The analysis did not show any significant difference in aspartate transaminase, alkaline transaminase, liver size, cholesterol, and triglyceride changes among the silymarin and placebo groups. BMI loss was slightly higher in the silymarin group although the difference was not statistically significant. Conclusion: The present findings show that silymarin administration for 4 weeks does not affect liver size and function, but further evaluations should be carried out on the subject.
