Asymptomatic ureteral metastasis of chromophobe renal cell carcinoma after radical nephrectomy: A case report and review of literature.

INTRODUCTION: Standard treatment for renal cell carcinomas (RCCs) is radical/partial nephrectomy and unlike upper urothelial carcinoma, complete ureteral removal is not necessary nor is advised in RCCs as tumor recurrence in ureteral remnant has scarcely been reported. Here, we present a rare case of chromophobe RCC (ChRCC) metastasis in remnant ureter following radical nephrectomy and perform a literature review in this regard. CASE PRESENTATION: A 66-year-old man presented with a CT scan-as a surveillance protocol imaging- showing a mass in ipsilateral remnant ureter 9 months after radical nephrectomy due to ChRCC while being completely asymptomatic. Cystoscopy revealed a polypoid mass protruding from right ureterovesical junction and transurethral resection of tumor revealed it to be a ChRCC. Distal ureterectomy was performed confirming pathology without any lymph node involvement. 12 months after ureterectomy, he remained asymptomatic with no sign of metastasis or recurrence in his follow up CT scan. DISCUSSION: RCC metastasis to distal ureter after radical nephrectomy has been rarely reported and only 2 cases of them were ChRCC. Gross hematuria has been the main presentation of such disease. However, our case was completely asymptomatic, highlighting necessity of surveillance imaging. No specific treatment guideline exists for such presentation but tumor resection has been the most common treatment modality. CONCLUSION: Metachronous RCC metastasis may occur in remnant ureter which can be completely asymptomatic, highlighting necessity of surveillance imaging and reviewing them meticulously. Surgical resection of the metastasis by distal ureterectomy seems to be the best treatment option.

Exosomes isolated from metabolically unhealthy normal weight and overweight phenotypes deteriorate the ER/PR positive breast cancer behavior.

Purpose: Obesity has been linked to a higher risk of postmenopausal breast cancer Yet, research indicates an opposite correlation between obesity and premenopausal breast cancer risk. Various obesity phenotypes based on metabolic health could play a significant part. This study aims to assess how plasma exosomes taken from women with varying obesity phenotypes impact MCF-7 cell migration, matrix metalloproteinase-2 activity, and apoptosis. Methods: The characterization of isolated exosomes and their internalization into MCF-7 cells was evaluated. The treatment of MCF-7 cells with exosomes isolated from different groups was done. Migration, the activity of MMP-2, mRNA expression of Bax and Bcl-2, protein expression of p-53 and Thr55 p-p53, and apoptosis were assessed. Results: Isolated exosomes from unhealthy obese individuals increase MCF-7 cell migration. Regarding MMP activities, unhealthy normal weight and overweight and healthy obese groups isolated exosomes increase the MMP-2 activity than the treated group with exosomes isolated from counterpart groups. Furthermore, unhealthy normal weight and overweight and healthy obese obtained exosomes decrease apoptosis compared to counterpart groups. Conclusion: Altogether, plasma exosomes derived from both unhealthy individuals with normal weight and overweight status, as well as those with unhealthy obesity, negatively impacted the behavior of estrogen/progesterone receptor-positive breast cancer cells.

Higher expression of SALL4-A isoform is correlated with worse outcomes and progression of the disease in subtype of testicular germ cell tumours.

BACKGROUND: The transcription factor SALL4 is associated with embryonic pluripotency and has proposed as a novel immunohistochemistry (IHC) marker for diagnosing germ cell tumours. SALL4 comprises three isoforms, and SALL4-A being the full-length isoform. Studying its isoforms could revolutionize testicular cancer prognosis and subtype differentiation. METHODS: The expression and clinical significance of isoform 'A' of SALL4 was evaluated in 124 testicular germ cell tumours (TGCTs) subtypes, adjacent 67 normal tissues and 22 benign tumours, using immunohistochemistry on tissue microarrays (TMA). RESULTS: A statistically significant higher expression of nuclear and cytoplasmic SALL4-A was detected in TGCTs histological subtypes and benign tumours compared to the normal tissues. Seminoma and yolk sac tumours had the highest nuclear and cytoplasmic expression of SALL4-A. A significant correlation was detected between the higher nuclear expression of SALL4-A and increased pT stages (P = 0.026) in seminomas. Whereas in embryonal carcinomas, cytoplasmic expression of SALL4-A was associated with the tumour recurrence (P = 0.04) and invasion of the epididymis (P = 0.011). CONCLUSIONS: SALL4-A isoform expression in the cytoplasm and nucleus of TGCTs may be associated with histological differentiation. In the seminoma subtype of TGCTs, higher expression of SALL4-A may be used as a predictive indicator of poorer outcomes and prognosis.

The therapeutic effect of alcoholic extract of Fumaria parviflora on high-fat diet-induced nonalcoholic fatty liver in rats: an animal experiment.

Background and purpose: Nonalcoholic fatty liver disease (NAFLD) is a growing problem with a significant burden. Lifestyle modification is the recommended treatment, but researchers are exploring other options. This study focused on the effects of Fumaria parviflora (FP) extracts on NAFLD induced by a high-fat diet in rats. Experimental approach: Thirty-five 10-week-old male Wister-Albino rats were divided into seven groups: normal diet control, high fat diet control, high fat diet with oral normal saline gavage, high fat diet with oral Atorvastatin gavage, and three groups receiving high fat diet with FP extract in 200 mg/kg, 400 mg/kg, and 700 mg/kg.Blood samples of rats were used for the measurement of total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride (TG), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP).1×1 cm Liver biopsies were taken, stained with Trichrome Stain (Masson) and Hematoxylin and eosin (H&E) stain for evaluation by a pathologist. Findings/results: Lab results showed that FP extract inhibits weight gain, has positive effects on triglyceride and alkaline phosphatase levels, and reduces hepatocyte ballooning and inflammation in rats. Conclusion: FP extract may lower liver enzymes and have a positive impact on triglyceride, LDL, and HDL levels in rats with NAFLD.

EBV-Associated Gastric Cancer; An In Situ Hybridization Assay on Tissue Microarray: A Multi-Region Study from Four Major Provinces of Iran.

BACKGROUND: Gastric cancer is the fourth leading cause of cancer-related deaths in the world. The identification of gastric cancer subtypes related to recognizable microbial agents may play a pivotal role in the targeted prevention and treatment of this cancer. The current study is conducted to define the frequency of Epstein-Barr virus (EBV) infection in gastric cancers of four major provinces, with different incidence rates of gastric cancers, in Iran. METHODS: Paraffin blocks of 682 cases of various types of gastric cancer from Tehran, South and North areas of Iran were collected. Twelve tissue microarray (TMA) blocks were constructed from these blocks. Localization of EBV in tumors was assessed by in situ hybridization (ISH) for EBV-encoded RNA (EBER). Chi-squared test was used to evaluate the statistical significance between EBV-associated gastric cancer (EBVaGC) and clinicopathologic tumor characteristics. RESULTS: Fourteen out of 682 cases (2.1%) of gastric adenocarcinoma were EBER-positive. EBER was positive in 8 out of 22 (36.4%) of medullary carcinomas and 6 out of 660 (0.9%) of non-medullary type, which was a statistically significant difference (P<0.001). The EBVaGCs were more frequent in younger age (P=0.009) and also showed a trend toward the lower stage of the tumor (P=0.075). CONCLUSION: EBV-associated gastric adenocarcinoma has a low prevalence in Iran. This finding can be due to epidemiologic differences in risk factors and exposures, and the low number of gastric medullary carcinomas in the population. It may also be related to gastric tumor heterogeneity not detected with the TMA technique.

Overexpression of Transmembrane Phosphatase with Tensin homology (TPTE) in prostate cancer is clinically significant, suggesting its potential as a valuable biomarker.

PURPOSE: Cancer testis antigens (CTAs) are a family of proteins typically expressed in male testicles but overexpressed in various cancer cell types. Transmembrane Phosphatase with Tensin homology (TPTE) is expressed only in the testis of healthy individuals and is a member of the family of CTAs. The current study, for the first time, examined the significance of TPTE expression in prostate cancer (PCa) tissues by generating a novel antibody marker targeting TPTE protein. METHODS: Polyclonal antibodies were prepared for TPTE-p1 and TPTE-p2 peptides, which are derived from the extracellular domains of TPTE. Anti-TPTE-p2 antibody was then used to study the extent and pattern of TPTE expression in 102 PCa and 48 benign prostatic hyperplasia (BPH) tissue samples by immunohistochemistry. The viability of cancer cell lines (PC-3 and MCF-7 cells) was also evaluated in the presence of anti-TPTE-p2 antibody using the MTT test. RESULTS: The immunohistochemical analysis demonstrated a significant increase in cytoplasmic and membrane TPTE expression in the PCa samples compared to the BPH group (both P < 0.0001). Cytoplasmic TPTE expression was positively correlated with Gleason score and PSA levels (P = 0.03 and P = 0.001, respectively). Significant correlations were identified between the levels of PSA and perineural invasion and the membrane expression (P = 0.01, P = 0.04, respectively). Moreover, anti-TPTE-p2 antibody inhibited PC-3 and MCF-7 cells proliferation compared to the control group for 24 h (P < 0.001 and P = 0.001, respectively) as well as for 48 h (P = 0.001 and P = 0.001, respectively). CONCLUSION: Our findings indicate that increased TPTE expression is associated with progression of disease. The ability of anti-TPTE-p2 antibody to recognize and target the TPTE protein makes it a potential biomarker to assess and/or target the PCa.

Metabolically healthy/unhealthy obesity and breast cancer: A possible role of plasma-derived extracellular vesicles on the cancerous behavior of triple-negative breast cancer.

PURPOSE: Obesity has known detrimental effects on breast cancer (BC) development and progression. However, it's essential to consider the obesity phenotype based on metabolic health. This study aims to evaluate the impact of circulating extracellular vesicles (EVs) from women with metabolically healthy or unhealthy normal weight, overweight, and obesity on MDA-MB-231 cell migration, invasion, and apoptosis. METHODS: Plasma EVs were isolated from different obesity phenotypes in women. EVs were characterized and EVs uptake by MDA-MB-231 cells was assessed. MDA-MB-231 cell lines were treated with EVs obtained from various studied groups, and migration, invasion, MMP-2 and MMP-9 activity, Bax and Bcl-2 mRNA expression, p-53 and Thr55 p-p53 protein expression, and apoptosis were assessed. RESULTS: EVs from obese individuals, regardless of phenotype, increased invasion and MMP-2 activity compared to healthy normal-weight EVs. Normal-weight EVs led to higher invasion under unhealthy conditions. BC cell migration was enhanced by EVs from healthy obese individuals compared to healthy normal-weight EVs. EVs from unhealthy obese women exhibited significantly lower p53/p-p53 levels and reduced apoptosis compared to healthy obese groups. CONCLUSION: It appears that EVs from both normal-weight women with unhealthy conditions and those with obesity or overweight, irrespective of metabolic status, worsened the cancerous behavior of TNBC cells. Therefore, considering metabolic health, in addition to BMI, is crucial for understanding obesity-related disorders.

P53, CK20, and FGFR3 Overexpression is Associated with the Characteristics of Urothelial Cell Carcinoma of the Bladder

OBJECTIVES: The aim of this study was to investigate the association between the overexpression of tumor protein (P53), cytokeratin 20 (CK20), fibroblast growth factor receptor 3 (FGFR3), biomarkers and the grading, prognosis, heterogeneity, and relapse tendency of urothelial cell carcinomas (UCCs) of the bladder. METHODS: A cross-sectional study was conducted using 413 samples of Iranian patients diagnosed with UCC of the bladder. The tissue microarray technique was used to evaluate the patterns of tumor tissue. Two pathologists scored tissue staining using a semi-quantitative scoring system. RESULTS: The results showed that P53 was a predictor of a high-grade pattern (the area under the curve (AUC)=0.620) with a best cut-off value of 95.0 using the receiver operating characteristic (ROC) curve. CK20 was another predictor of a high-grade pattern (AUC=0.745) with a best cut-off value of 15. However, the overexpression of both biomarkers was not associated with a heterogeneous pattern and could not predict tumor-associated death or relapse. The heterogeneous (odds ratio (OR)=4.535, p-value=0.001) and non-papillary (OR= 6.363, p-value= 0.001) patterns were effective predictors of tumor recurrence among all baseline variables, including patient and tumor characteristics. FGFR3 was positive in all specimens and was not a valuable biomarker for differentiating patterns. None of the variables predicted tumor prognosis. CONCLUSION: The study findings indicate that the intensity and percentage of cell staining for P53 and CK20 in the UCC of the bladder can aid in differentiating the grading patterns. The tendency of tumor relapse can be predicted by demonstrating heterogeneous and non-papillary patterns.

The uterine adenosarcoma with postoperative residual in a woman treated by total abdominal hysterectomy/bilateral salpingo-oophorectomy: A case report and review of literature.

BACKGROUND: In patients with uterine adenosarcoma, a total abdominal hysterectomy (TAH) with bilateral salpingo-oophorectomy (BSO) is typically recommended as an initial treatment. There is no consensus on adjuvant therapies. CASE: We report the case of a patient with uterine adenosarcoma with postoperative residual disease. We performed four courses of adjuvant chemotherapy, including Ifosfamide, Mesna, and Adriamycin, and whole pelvic radiation with a dose of 50.4 Gy/28 Fr. CONCLUSION: A combination of chemotherapy and radiotherapy may be a promising treatment option for uterine adenosarcoma with postoperative residual disease.

Pemphigus vulgaris and focal segmental glomerulosclerosis (FSGS): First reported case and a review of the literature.

Key Clinical Message: There may be a connection between pemphigus vulgaris and nephrotic syndrome, as evidenced by the occurrence of focal segmental glomerulosclerosis in our pemphigus vulgaris patient and reviewing relevant literature. Therefore, if a patient with pemphigus vulgaris presents with bilateral lower extremity edema or proteinuria detected during urinalysis, it could indicate involvement of the kidneys. Abstract: Pemphigus vulgaris is a type of autoimmune blistering disease characterized by the presence of IgG autoantibodies against desmogleins 3 and 1. It is important to evaluate potential autoimmune associations in patients with pemphigus vulgaris so that appropriate laboratory and physical examinations can be performed to monitor for any increased risk of other autoimmune disorders. This case report describes a 55-year-old woman who presented with oral and axillary erosions, which were diagnosed as pemphigus vulgaris based on skin histopathology and immunofluorescence. During follow-up, the patient was found to have proteinuria, which led to referral to a nephrologist. The patient was diagnosed with nephrotic syndrome and minimal change disease after a biopsy. Despite treatment, the patient's proteinuria persisted and serum creatinine levels increased, leading to a second biopsy which confirmed the diagnosis of focal segmental glomerulosclerosis. This study reports on the first case of pemphigus vulgaris with focal segmental glomerulosclerosis and reviews the literature on the co-occurrence of acquired immunobullous diseases and nephrotic syndrome of any kind.

Nutrition, Physical Activity, and Prescription of Supplements in Pre- and Post-bariatric Surgery Patients: An Updated Comprehensive Practical Guideline.

Only in the USA, 315 billion dollars are spent annually on the medical cost of obesity in adult patients. Till now, bariatric surgery is the most effective method for treating obesity and can play an essential role in reducing the direct and indirect costs of obesity treatment. Nonetheless, there are few comprehensive guidelines which include nutrition, physical activity, and supplements, before and after surgery. The purpose of the present narrative review is to provide an updated and comprehensive practical guideline to help multidisciplinary teams. The core keywords include nutrition, diet, physical activity, exercise, supplements, macronutrients, micronutrients, weight reduction, bariatric surgery, Roux-en-Y Gastric Bypass, Sleeve Gastrostomy, Laparoscopic Adjustable Gastric Banding, and Biliopancreatic diversion with duodenal switch which were searched in databases including PubMed/Medline, Cochrane, and some other sources such as Google Scholar. We answered questions in five important areas: (a) nutritional strategies before bariatric surgery, (b) nutrition after bariatric surgery, (c) physical activity before and after bariatric surgery, (d) weight regain after bariatric surgery, and (e) micronutrient assessments and recommendations before and after bariatric surgery. Some new items were added in this updated guideline including "weight regain" and "pregnancy after bariatric surgery." Other fields were updated based on new evidence and guidelines.

Association of body mass index and physical activity with fatigue, depression, and anxiety among Iranian patients with multiple sclerosis.

Introduction: Depression, fatigue, and anxiety are three common clinical comorbidities of multiple sclerosis (MS). We investigated the role of physical activity (PA) level and body mass index (BMI) as modifiable lifestyle factors in these three comorbidities. Methods: A cross-sectional study was conducted in the MS specialist clinic of Sina Hospital, Tehran, Iran. Demographic and clinical data were collected. BMI was categorized in accordance with the WHO's standard classification. Physical activity (PA) level and sitting time per day were obtained using the short form of the International Physical Activity Questionnaire (IPAQ-SF). Fatigue, anxiety, and depression scores were measured using the Persian version of the Fatigue Severity Scale (FSS), Beck Anxiety Inventory (BAI), and Beck's Depression Inventory II (BDI-II) questionnaires, respectively. The correlation between the metabolic equivalent of tasks (MET), BMI, and daily sitting hours with depression, anxiety, and fatigue were checked using the linear regression test. The normal BMI group was considered a reference, and the difference in quantitative variables between the reference and the other groups was assessed using an independent sample t-test. Physical activity was classified with tertiles, and the difference in depression, anxiety, and fatigue between the PA groups was evaluated by a one-way ANOVA test. Results: In total, 85 MS patients were recruited for the study. The mean ± SD age of the participants was 39.07 ± 8.84 years, and 72.9% (n: 62) of them were female. The fatigue score was directly correlated with BMI (P: 0.03; r: 0.23) and sitting hours per day (P: 0.01; r: 0.26) and indirectly correlated with PA level (P < 0.01; r: -0.33). Higher depression scores were significantly correlated with elevated daily sitting hours (P: 0.01; r: 0.27). However, the correlation between depression with PA and BMI was not meaningful (p > 0.05). Higher anxiety scores were correlated with BMI (P: 0.01; r: 0.27) and lower PA (P: 0.01; r: -0.26). The correlation between anxiety and sitting hours per day was not significant (p > 0.05). Patients in the type I obesity group had significantly higher depression scores than the normal weight group (23.67 ± 2.30 vs. 14.05 ± 9.12; P: 0.001). Fatigue (32.61 ± 14.18 vs. 52.40 ± 12.42; P: <0.01) and anxiety (14.66 ± 9.68 vs. 27.80 ± 15.48; P: 0.01) scores were significantly greater among participants in the type II obesity group in comparison with the normal weight group. Fatigue (P: 0.01) and anxiety (P: 0.03) scores were significantly different in the three levels of PA, but no significant difference was found in the depression score (P: 0.17). Conclusion: Our data suggest that a physically active lifestyle and being in the normal weight category are possible factors that lead to lower depression, fatigue, and anxiety in patients with MS.

Prognostic value of Talin-1 in renal cell carcinoma and its association with B7-H3.

METHODS: Talin-1 protein was demonstrated as a potential prognostic marker in renal cell carcinoma (RCC) using bioinformatics analysis. We, therefore, examined the protein expression levels and prognostic significance of Talin-1 with a clinical follow-up in a total of 269 tissue specimens from three important subtypes of RCC and 30 adjacent normal samples using immunohistochemistry. Then, we used combined analysis with B7-H3 to investigate higher prognostic values. RESULTS: The results showed that high membranous and cytoplasmic expression of Talin-1 was significantly associated with advanced nucleolar grade, microvascular invasion, histological tumor necrosis, and invasion to Gerota's fascia in clear cell RCC (ccRCC). In addition, high membranous and cytoplasmic expression of Talin-1 was found to be associated with significantly poorer disease-specific survival (DSS) and progression-free survival (PFS). Moreover, increased cytoplasmic expression of Talin-1High/B7-H3High compared to the other phenotypes was associated with tumor aggressiveness and progression of the disease, and predicted a worse clinical outcome, which may be an effective biomarker to identify ccRCC patients at high risk of recurrence and metastasis. CONCLUSIONS: Collectively, these observations indicate that Talin-1 is an important molecule involved in the spread and progression of ccRCC when expressed particularly in the cytoplasm and may serve as a novel prognostic biomarker in this subtype. Furthermore, a combined analysis of Talin-1/B7-H3 indicated an effective biomarker to predict the progression of disease and prognosis in ccRCC.

Production and characterization of a new specific monoclonal antibody against A-isoform of SALL4: A novel emerging testicular cancer marker.

SALL4 transcription factor plays an important role to maintain the pluripotent and self-renewal of embryonic stem cells. It contributes to the growth of many cancers and embryonic development. With the exception of spermatogonia, SALL4 expression is silenced in most adult tissues after birth; nevertheless, it is re-expressed in a subset of different solid malignancies. SALL4 is a new, precise biomarker for testicular germ cell cancers that was just introduced. The whole isoform of SALL4 is called SALL4-A. Regarding the lack of antibody against human SALL4 isoforms, the pattern of expression, the role of each isoform remain unknown. Furthermore, in isoform specific evaluations, we aimed, for the first time, to produce and characterize mAb against human SALL4-A. Immunization of mice were performed with a selected 33-mer synthetic peptide of SALL4-A conjugated with KLH. Hybridoma cells were screened by ELISA for positive reactivity with SALL4-A peptide. From the ascites fluid of mice that had been injected with hybridoma cells, anti-SALL4-A mAbs were isolated using a protein G column. Reactivity of the mAbs was evaluated using the peptide and SALL4-A recombinant protein by ELISA and IHC on testicular cancer tissue as positive control, and normal kidney, stomach and prostate tissues as negative control. The produced mAb could well detect SALL4-A in testicular cancer tissues using IHC, while the reactivity was negative in normal kidney, stomach and prostate tissues. Using ELISA, the mAb affinity for the peptide and SALL4-A recombinant protein was assessed, and it was shown to be reasonably high. The mAb detected SALL4-A in nucleus and cytoplasm of several cancer cells and spermatogonia in testicular cancer tissue. In addition, it could recognize SALL4-A recombinant protein. Our produced monoclonal antibody against isoform-A of human SALL4 can specifically recognize SALL4-A using either IHC or ELISA. We hope that this mAb could help researchers in isoform-specific study of human SALL4.

Effect of eight weeks respiratory muscle training on respiratory capacity, functional capacity and quality of life on subjects with mild to moderate relapsing-remitting multiple sclerosis: A single-blinded randomized controlled trial.

BACKGROUND: Multiple Sclerosis (MS) is a chronic inflammatory disease of the nervous system leading to muscle weakness, including the respiratory muscles that cause pulmonary complications, impair functional capacity, increased fatigue, and as a result decreases the quality of life. AIM: The purpose of the present study is to examine the influence of 8 weeks of respiratory muscle training (RMT) on pulmonary function and respiratory muscle strength in MS patients. METHODS: The present study was a single-blind, randomized controlled trial that was conducted on 36 (27 Female, 9 Male) relapsing-remitting MS patients who were definitively diagnosed by a neurologist and randomly were divided into intervention and control groups. Both groups were educated on lifestyle modification with an emphasis on regular physical activity. In addition, the intervention group was prescribed eight weeks of respiratory muscle training with a threshold resistance device, daily, twice a day for three sets of 15 repetitions per set. Maximal expiratory pressure (PImax), maximal expiratory pressure (PEmax), spirometric indices, functional tests (six-minute walk test, timed up and go test), fatigue questionnaire, and questionnaire of quality of life were assessed before and after trials. RESULTS: A total of 36 patients (75% female; mean age 38.00(8.86) years; BMI 26.56(2.64) kg/m2) were included in the study. The strength of inspiratory and expiratory muscles, respiratory function, fatigue, and quality of life were significantly improved in the intervention group (p<0.005). In addition, there was a significant improvement in the rate of fatigue and quality of life in all their dimensions (p<0.005). Only in the six-minute walk test, no significant improvement was seen in the intervention group compared to the control group (p = 0.262). CONCLUSION: Findings could help therapists to provide MS patients with more effective respiratory muscle training protocols to maximize the benefits of rehabilitation.

The impact of bariatric surgery procedures on the modulation of cardiometabolic risk factors in patients with severe obesity: a 12-month follow-up.

OBJECTIVE: To evaluate the effects of one anastomosis gastric bypass (OAGB), Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG) on cardiometabolic risk factors (CMRFs) in patients with severe obesity. METHODS: This retrospective cohort study included patients with severe obesity who had undergone OAGB, RYGB, or SG between 2015 and 2017 and follow-up assessments over 12-months. RESULTS: Among 485 included patients, anthropometric measurements, body composition, fasting blood glucose (FBG), lipid profile, and comorbidities were significantly improved for all three procedures throughout the follow-up period. Weight, % total weight loss (%TWL), body mass index, fat mass and fat mass to fat-free mass ratio improvements were higher with RYGB and OAGB than SG. There were no significant differences between procedures in all other variables. A significant trend toward remission rate of dyslipidemia and type 2 diabetes mellitus was observed with all three procedures, with no significant difference between the three groups. %TWL statistically correlated with fat mass, FBG, and triglycerides. CONCLUSIONS: OAGB, RYGB, and SG had a beneficial impact on CMRFs and comorbidities during 12 months of follow-up. Of note, RYGB and OAGB may result in better outcomes, particularly anthropometric and body composition indices. Further large-sample, long-term follow-up studies are required to expand on the present findings.

Malignant mixed epithelial and stromal tumor of the kidney with rhabdomyosarcomatous transformation presenting with gross hematuria.

Malignant rhabdomyosarcoma associated with mixed epithelial and stromal tumor of the kidney (MESTK) is an exceptionally rare clinical phenomenon, with only two reported cases. Here, we describe the case of a middle-aged Middle Eastern woman with a left renal mass diagnosed as malignant MESTK with rhabdomyosarcomatous transformation. The patient initially presented with gross hematuria and was found to have a heterogenous 6.3 × 4.0 cm left renal mass, initially suspected to be renal cell carcinoma. She underwent nephrectomy with surgical resection of the tumor. Microscopic exam revealed neoplastic tissue composed of spindle and epithelial cells. The immunohistochemical analysis revealed positive staining for desmin, SMA, PR and negative staining for EMA, HMB 45, Melan A, and ER, consistent with MESTK with malignant rhabdomyosarcomatous transformation. The patient's whole-body positron emission tomography/computed tomography revealed no residual malignancy, and the patient currently remains under clinical observation.

Food Addiction and Binge Eating Disorder in Relation to Dietary Patterns and Anthropometric Measurements: A Descriptive-Analytic Cross-Sectional Study in Iranian Adults with Obesity.

Obesity is associated with maladaptive eating behaviors, including food addiction (FA) and binge eating disorder (BED). However, the key factors influencing the development of maladaptive eating behaviors remain unknown. Adherence to specified dietary patterns has been suspected of making indirect impacts. This study investigates the association of FA and BED with dietary patterns and anthropometric measurements among 400 Iranian adults (aged 18-60; 66.25% women) living with obesity (body mass index [BMI] ≥ 30 kg/m2). The Binge Eating Scale and Yale Food Addiction Scale were used to measure BED and FA. A validated 147-item semi-quantitative food frequency questionnaire underwent principal component analysis and identified three major dietary patterns: mixed, unhealthy, and healthy dietary pattern. After adjusting for confounders, higher adherence to unhealthy dietary patterns was associated with an increased risk of FA, while higher adherence to healthy dietary patterns was associated with a lower risk of FA. Also, those within obesity class III had a significantly higher risk of FA and BED than those in obesity class I. This study suggests that adherence to an unhealthy dietary pattern may be associated with a higher risk of FA. It also highlights the link between higher BMI and maladaptive eating behaviors.

Effect of endurance training on cardiopulmonary fitness in people with multiple sclerosis.

INTRODUCTION: Disturbances associated with Multiple Sclerosis (MS) can be due to the pathologic process of the disease or insufficient physical fitness. The benefits of exercise in improving cardiopulmonary fitness have been demonstrated in animal studies and also clinical trials on cardiovascular patients and healthy human cases; however, its effectiveness in people with MS(pwMS) is still unknown. people with MS often engage in rehabilitation programs for exercise tolerance improvement. Therefore, it is necessary to investigate the effect of this specific intervention on cardiopulmonary fitness of these patients. The present study intended to illustrate the etiology of exercise intolerance in pwMS and also the effects of exercise on these etiological factors. METHODS AND RESULTS: The present interventional study included 21 female patients suffering from Relapsing-Remitting MS (RR-MS) who had a mean age of 35 ± 5.18 years and the Expanded Disability Status Scale (EDSS) scores of 1 to 4. All the participants underwent Cardiopulmonary Exercise Testing (CPET) on an ergometer pre- and post-intervention. The intervention included 18 sessions of endurance training using a stationary bicycle with an intensity of 70% of the peak Heart Rate (HR) or 60% of the peak VO2 (Volume of oxygen consumption) under the supervision and cardiac monitoring. A total of 24 variables, including the parameters cardiopulmonary fitness (aerobic fitness), were investigated. Also, all the maximal variables were analyzed in the same RER(Respiratory Exchange Ration) (a mean RER of 0.92) pre- and post-intervention. According to the results, a total of 17 variables out of 24 study variables had significant changes (P < 0.05). CONCLUSION: The present study showed that even a short, 6-week course of aerobic exercise could change the peak HR and VO2, improving the cardio pulmonary fitness in these patients. This indicates the adaptation of the cardiopulmonary system to exercise in pwMS. In other words, these cardiopulmonary fitness variables improvement due to exercise demonstrates that this pathology is not merely caused by the MS-induced Central Nervous System (CNS) involvement and can be improved by improving cardiopulmonary fitness.
