Background/Aim: Previous studies have demonstrated that patients with obesity can be metabolically healthy. However, little is known about the healthy or unhealthy metabolic status of patients undergoing bariatric surgery. This study, therefore, assesses the prevalence of metabolically healthy (MHO) and unhealthy (MUO) obesity among bariatric surgery candidates. Methods: The study involved 713 bariatric surgery candidates (580 women and 133 men; age range 18-69 years). MHO and MUO were defined according to The National Cholesterol Education Program-Adult Treatment Panel III (ATP III). Results: Mean (±SD) patient age, weight, body mass index (BMI), waist and hip circumference were 40.44 (±10.26) years, 127.15 (±22.15) kg, 164.33 (±8.85) cm, 46.90 (±5.79) kg/m2, 122.57 (±13.93) cm, and 140.10 ( ±12.40) cm, respectively. 318 patients (44.6%) were classified as MHO and 395 (55.4%) as MUO. A higher percentage of participants aged 40 years and older suffered from unhealthy metabolic status (61%). Conclusion: A large percentage of bariatric surgery candidates are metabolically healthy. Additionally, the prevalence of MHO was higher at younger ages

Published: March 2022

Background: Roux-en-Y gastric bypass (RYGBP) has received a lot of attention with the prevalence of obesity. However, some patients report more weight loss and more malnutrition, which is thought to be due to differences in common Limb length (CLL) in patients. Surgeons reported alimentary limb length (ALL) and biliopancreatic limb length (BPLL), and CLL is generally unknown. Methods: During 2015-2017, this study was conducted among 600 patients to evaluate CLL and excessive weight loss (EWL) and malnutrition in patients undergoing RYGBP. To measure the length of the small intestine, 30 minutes after the start of the surgery, the measurement was performed by micro forceps and grasping the midpart of the small intestine and, the average measurement time was 7 minutes. Results: the median length of the small bowel was 712 cm. The results of this study showed that patients with CLL ˂650 cm had more EWL% and malnutrition than CLL >750 cm. Conclusion: Since 0.5% and 2% of the participants in this study had a small bowel length of fewer than 4 m and 4.5 m, respectively, and assuming that the ALL + CLL should be more than 3 m, the length of the small bowel was usually bypassed in these people is 2 meters. If the BPLL is less than 125 cm, small bowel measurement is not necessary, but if it is higher than 125 cm, 2% of people will have the chance of shortness of small bowel and it is better to measure the length of the intestine.

Background: An enlarged liver, which is resulted from fatty liver and/or steatohepatitis, makes difficulties in gastric bypass surgery procedure and increases the risk of liver laceration. omega-3 polyunsaturated fatty acids (ω-3 PUFAs) recently have been suggested as a potential intervention to reduce liver inflammation and volume. This review aimed to provide a comprehensive overview of the recent advances on fish oil/ ω-3 PUFAs supplementation to reduce the liver volume proceeding to bariatric surgery. Methods: This review summarizes studies that were investigated the influence of fish oil/omega-3 PUFA in the liver volume of bariatric surgery candidates. Scopus and PubMed databases were systematically searched up to May 2021, for studies providing knowledge relating to the effects of omega-3 and/or fish oil supplementation on liver size, fatty liver, or steatohepatitis. Results: Most of the randomized controlled trials showed that ω-3 PUFA supplementation, mostly due to its anti-inflammatory and antioxidative properties, is a practical and effective treatment for fatty liver, and to decrease ALT, AST, and GGT. Omega-3 fatty acids as important regulators of hepatic gene transcription can reduce hepatic steatosis and inflammation markers, also improve insulin sensitivity. As well, the access to the gastroesophageal junction was reported as simple. Conclusion: The collective data suggest that preoperative fish oil ω-3 PUFA supplementation could be an effective approach in improving liver function and decrease liver volume before bariatric surgery. Although, well-designed randomized clinical trials are needed to confirm these results and determine a clear protocol of supplementation regarding the optimal dose and duration before surgery.

Background: The aim of this study was to evaluate the prevalence of H.pylori, before and one year after Roux-en Y gastric bypass surgery. Method: The laparoscopic research center database from 2018 to 2020 was queried to identify patients undergoing laparoscopic Roux-en Y gastric bypass surgery(LRYGB). Retrospectively, the patients were evaluated for the presence of H.pylori infection via endoscopy or H. pylori Stool Ag before and 1 year after the surgery. Results: Among the 106 patients, H.pylori was positive in 50 (47.2%) patients pre-operatively. Based on post-op evaluation among 54 patients, only 4 (7.4%) developed post-op H.pylori infection. Conclusion:. eradicating H. pylori in patients under Roux-en Y gastric bypass surgery remains efficient. So, it is not recommended to re-checked H.pylori Ag in patients after Roux-en Y gastric bypass surgery in the short term; but, further studies are suggested to evaluate the need for re-screening patients for H.pylori Ag in the long term after Roux-en Y gastric bypass surgery Keywords: Helicobacter Pylori; Iran;LRYGB.

Background: The association between gastroesophageal reflux disease (GERD) and obesity with a prevalence of 50-100% has been proven, while 8-26% of non-obese patients experienced GERD. Laparoscopic Roux-en-Y gastric bypass (LRYGB) is considered the gold standard for obese patients with GERD. RYGB can accelerate gastric emptying and thus improve reflux symptoms. Case presentation: A 56-year-old man weighing 101 kg and 167 cm tall (BMI 36.2) presented to the hospital with major complaints of obesity and mild gastroesophageal reflux disease. He also suffered from comorbidities like DM, HTN, and IHD. 15 years ago he underwent Nissen Fundoplication due to severe GERD. We candidate the patient for LRYGB surgery because of obesity, Mild reflux, and comorbidities such as DM, and HTN. Due to past fundoplication, severe adhesions, and fibrosis at the last operation site, LRYGB without Wrap taken down was done. Discussion: Laparoscopic conversion of Fundoplication to RYGB is a complex technique because of extended operative time, morbidity, and length of hospital stay. RYGBP after fundoplication leads to more complications than other forms of reoperative bariatric surgery; however, it gives a good weight loss that satisfies the patient. Conclusion: LRYGB after previous anti-reflux surgery without wrap takedown is technically safe and brings in reflux symptoms and comorbidities improvement, satisfactory weight loss, and less morbidity.

Background and aim: Intense training and competition lead to fatigue and muscular imbalance in wrestlers that cause postural abnormalities. Thus, it is important to identify these changes and the related mechanisms to prevent musculoskeletal and sports injuries among wrestlers. The present study is a comprehensive review of the literature on postural changes in freestyle and Greco-Roman wrestlers. Materials and Methods: This paper offers a thorough review of the literature on changes in freestyle and Greco-Roman wrestlers. It encompasses a series of search queries from inception to Mar 2020 from existing databases including PubMed/MEDLINE, EBSCO Web of Science, Science Direct, Cochrane Central Register of Controlled Clinical Trials, Google Scholar, and Scopus. A host of other publications were also reviewed manually. Once candidate papers were extracted, the title and abstract were studied and those meeting the inclusion criteria were selected for further analysis and the others were discarded. Results: A total number of 11 papers were selected. Overall, 4 papers studied postural changes in wrestlers; 2 studied Q angle and flat foot; and 5 compared the two wrestling styles. Conclusion: Results show that estimated changes in kyphosis, lordosis, forward shoulder, forward head, Q angle, and flat foot were higher among wrestlers. However, kyphosis angle was higher among freestyle wrestlers while a higher lordosis angle was observed for Greco-Roman wrestlers. Moreover, a higher degree of flat foot and Q angle was observed in the dominant leg of experienced freestyle wrestlers. Results of forward shoulder and forward head were contradictory and more studied need to be done.

Comparing Dominant and Non-Dominant Hand Performance with Force Changes In a Two-Hand Equilibrium Task: A Challenge to Dominant Hand Theories
Authors: Khanjari Yaser
Published: March 2022

Objective: Although most studies believe that the dominant hand performs better than the non-dominant hand in performing various tasks, there is still the challenge among researchers as to why the non-dominant hand performs better than the dominant hand in certain situations and tasks. The aim of this study was to compare dominant and non-dominant hand performance with force changes in a two-handed balance task. Methods: The samples of this study consisted of 30 male and female subjects with a mean and standard deviation of 28 ± 6.5 years. This research was conducted in Shiraz Health Center. In this study, a Huber device was used to measure hand function. Results: The results of the independent t-test showed that when the force on the handle sensor was the same in both hands, the performance of the dominant and non-dominant hand did not differ significantly (P>0.05). However, the dominant hand performed better when the dominant hand-applied more force and the non-dominant hand performed better than the dominant hand when the non-dominant hand applied more force to the handles (P<0.05). Conclusion: The results of this study showed that the performance of the superior hand is not always better than the non-superior hand and the performance of both hands depends on the type of task, synthetic factors (force), and the amount of attention to each hand.

Objective Excessive dynamic knee valgus, as a defective movement pattern, predisposes patients to lower limb injuries. Therefore, the aim of the present study was to study dynamic knee valgus in male soccer players. Methods In this review article, an attempt was made to collect studies conducted on the subject of research from 2000 to June 2021. The websites Google Scholar, PubMed, Science Direct, SID, ISC and Magiran were used and keywords related to the topic were used to search for articles. Results According to the search method, 50 articles were found, which were finalized according to the inclusion and exclusion criteria of 12 articles. Finally, 7 articles were reported in the present study. Dynamic knee valgus condition is more common in women than men, and varus are more common with increasing age of male soccer players. Different situations during the game such as tackling, jumping, imbalance after strike to the ball and landing after jumping are also among the situations that are associated with increased dynamic knee valgus and players are exposed to knee injury. The first minutes of the halves due to the lower angle of flexion of the knee and also late in the game due to fatigue can increase the dynamic valgus and increase the risk of knee injury. Conclusion All studies have pointed to the role of dynamic valgus in the incidence of knee joint injuries, especially the anterior cruciate ligament, so it is necessary to identify the mechanism of injury and correct the direction of dynamic valgus among soccer players.

Background: Adhesive capsulitis or frozen shoulder is among the most prevalent causes of pain and disability in individuals. We aimed to evaluate the effect of Photobiomodulation (PBM) on pain, range of motion, and thickness and function of supraspinatus muscle in patients with adhesive capsulitis. Materials & Methods: Overall, 52 subjects (n=26/group) with adhesive capsulitis referring to Poorsina Hospital, physiotherapy ward, Rasht City, Iran, in 2019 participated in this study. They were randomly assigned to 2 groups of control or routine physical therapy and PBM group. The variables were pain (VAS), range of motion (goniometer), the supraspinatus muscle thickness in rest and contraction, and muscle function (ultrasonography). The outcomes were examined before, after 5 and 10 sessions, and at a 1-month follow-up. Results: There were no significant differences between the two groups regarding the demographic characteristics and studied variables. The interaction of group and time (2×4) was significant for pain (P=0.02). Finally, the Bonferroni post hoc test data indicated the pain reduction in the PBM group was higher than the control group at the follow-up (P=0.03). The mixed two-factor analysis of variance indicated that the interaction of the group and time of shoulder abduction (P=0.6), shoulder external rotation (0.46), supraspinatus muscle thickness, rest (0.31), supraspinatus muscle thickness, contraction (0.11), and rest-contraction (0.66) were not significant. Conclusions: The PBM revealed greater analgesic effects than routine physical therapy in the short term and one-month follow-up. However, the effects on a range of motion and muscle thickness and function were insignificant.

Background: Alzheimer's disease (AD) is the most common type of dementia. The role of genetic factors in the development of AD has not been demonstrated yet. Objectives In this study, our aim was to investigate the association between one of the BIN1 gene’s single-nucleotide polymorphism (SNP( (rs744373) and late-onset Alzheimer's disease (LOAD) in an Iranian population in the Guilan province. Materials & Methods: In this case-control study, 110 patients with LOAD, and 110 unrelated healthy controls were recruited. Polymerase chain reaction-restriction length polymorphism (PCR-RFLP) was performed for genotyping BIN1 gene’s SNP (rs744373). Electrophoresis was there after carried out using agarose gel and DNA safe stain and the gels were visualized under an ultraviolet (UV) trans-illuminator. The allelic and genotypic frequencies were determined. Results: The frequency of allele T (Wild-type allele) in the control and the LOAD groups was 70.9% (n = 159) and 58.6% (n = 129), respectively (p = 0.007). The frequency of allele C in the LOAD group (41.4%) (n = 91) was significantly higher than that of the control group (29.1%) (n=64) (p=0.007). Frequency of homozygous genotype (CC) of BIN was significantly higher in the LOAD group than in the control group (p = 0.043). Conclusion: rs744373 SNP of BIN1 gene is significantly associated with the risk of developing AD in the studied population.
