There is no data on patients with severe obesity who developed coronavirus disease 2019 (COVID-19) after bariatric surgery. Four gastric bypass operations, performed in a 2-week period between Feb 24 and March 4, 2020, in Tehran, Iran, were complicated with COVID-19. The mean age and body mass index were 46 ± 12 years and 49 ± 3 kg/m 2 . Patients developed their symptoms (fever, cough, dyspnea, and fatigue) 1, 2, 4, and 14 days after surgery. One patient had unnoticed anosmia 2 days before surgery. Three patients were readmitted in hospital. All 4 patients were treated with hydroxychloroquine. In two patients who required admission in intensive care unit, other off-label therapies including antiretroviral and immunosuppressive agents were also administered. All patients survived. In conclusion, COVID-19 can complicate the postoperative course of patients after bariatric surgery. Correct diagnosis and management in the postoperative setting would be challenging. Timing of infection after surgery in our series would raise the possibility of hospital transmission of COVID-19: from asymptomatic patients at the time of bariatric surgery to the healthcare workers versus acquiring the COVID-19 infection by non-infected patients in the perioperative period.

The results of the present study suggest revising setting a contraindication for conception for patients undergoing bariatric surgery.

Any physiologic or pathologic situation can affect oral and dental health. Obesity and Bariatric surgery are two different factors which have their own signs and symptoms in the oral cavity. Soft tissue, hard tissue, oral flora and saliva can manifest changes in these patients and some intervention would be needed to control it. Our goal is to review oral manifestations in obese and bariatric patients to attract attention to oral care in these patients.

Introduction Multidisciplinary care after bariatric surgery is essential for long-term safety and optimal weight loss. However, many patients do not participate in routine postoperative follow-ups. We have explored the determinants of patients’ adherence to scheduled follow-up visits after bariatric surgery. Method A retrospective cohort study was performed on patients who underwent bariatric surgery from 2009 to 2019. Cohort participants with a proportion of attendance above the median were compared with those below the median in the first-year post-operation and the period after that. We assumed that the contribution of each predefined session to the overall attendance at eligible sessions is not equal. We weighted each predefined session by the proportion of attendance of all cohort members scheduled for that session. We then calculated the proportion of attendance for each individual at each period. Discriminatory logistic regression was used to identify factors separating adherers from non-adherers. Results We followed 5245 patients who underwent bariatric surgery for up to 10 years. The median follow-up was 2 years. Patients with the following characteristics were more likely to comply with the postoperative attendance schedule: female sex, older age, higher body mass index at the first visit, non-smoker, readmission after surgery, being operated in a general hospital, and one-anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) surgery type. Comorbidities did not significantly affect patients’ adherence to the predefined follow-up schedules. Conclusion Younger male smokers are more likely non-adherers. Patients with comorbidities are not at an increased risk of missing predefined postoperative follow-up visits.

Background and Objectives: To evaluate the association between menstrual cycle disorders with obesity in Iranian women. Methods & Materials: In the present case-control study, 405 obese women of reproductive age who referred to the Obesity Clinic of Minimally Invasive Surgery Research Center, Rasoul-e-Akram Hospital, Tehran, between Jan 2013 and Oct 2015 were included as the case group and were compared with a control normal-weight group, selected from their family members (N=293). Menstrual cycle characteristics were documented in a researcher-designed checklist. For the statistical analysis, we used SPSS version 19 and Stata version 5.0. Results: In the case group, 47 women (11.6%) had irregular menstrual cycles, while it existed in 22 (7.5%) of the control group (P<0.001). The prevalence of different menstrual disorders was as follows: polymenorrhea 107 (26.4%) in cases and 51 (17.4%) in controls (P<0.001), oligomenorrhea 22 (5.4%) in cases and 16 (5.5%) in controls (P<0.001). Conclusion: The results of the present study showed that morbid obesity increases the risk of menstrual irregularities and dysmenorrhea; therefore, it is essential to pay greater attention to this issue in morbid obese patients for proper management of this disturbing comorbidity.

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 LMS (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.

The aim of this study was to describe three neglected pregnancy at the time of bariatric surgery (BS) who had negative pregnancy test before surgery and underwent single-anastomosis gastric bypass surgery in obesity clinic in Rasoul-e-Akram Hospital, Iran University of Medical Sciences, Tehran, Iran. The first case was a 38 years old woman with BMI of 47.1 suffering from nausea and vomiting one month after surgery that medical treatment did not work and it was found positive βHCG test as and 13W + 6D fetus in sonography. The second case was a 30 years old woman with BMI of 46.2 suffering uterus bleeding four months after surgery. The third case was a 32 years old woman with BMI of 44.6 with suffering from resistant nausea and vomiting, epigastric pain, and delayed mense three month after surgery. These cases show the necessity of βHCG test at the time of bariatric surgery for childbearing females.
