Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder. OBJECTIVE This study aimed to evaluate red blood cell distribution width (RDW) and mean platelet volume (MPV) as laboratory markers to discriminate IBS patients from both healthy controls and patients with inflammatory bowel disease (IBD). METHODS This case-control study enrolled patients referred to Ayatollah Rouhani Hospital, Endoscopy Department, Babol, Iran, for colonoscopy examination from 2015 to 2017. Fifty IBS patients were selected from among patients who had undergone a normal colonoscopy and showed symptoms matching the Rome III criteria. Fifty healthy participants and 50 IBD patients, matched for sex and age, were also enrolled in this study. Both RDW and MPV were measured and analysed by independent sample t-test and receiver operating characteristic curve analysis. A p-value of less than 0.05 was considered statistically significant. RESULTS While RDW was higher and MPV was lower among IBS patients compared to healthy controls (p = 0.047 and p = 0.001), there were no significant differences in RDW or MPV levels between IBS and IBD patients. The area under the curve of RDW in the discrimination between IBS and IBD was 0.620 (p = 0.039), and the area under the curve of MPV in the discrimination between healthy controls and IBS patients was 0.801 (p = 0.001). CONCLUSION Mean platelet volume is potentially a useful laboratory marker for distinguishing between IBS patients and healthy individuals. Red blood cell distribution width should be considered as a potential marker to distinguish among IBS and IBD patients.

Abstract
INTRODUCTION About one third of patients referring to emergency department (ED) with abdominal pain, are discharged without a definite diagnosis. This study aimed to investigate the one-month outcome of patients with unspecified abdominal pain. METHODS This cohort study was conducted on subjects who were evaluated in ED with unspecified abdominal pain and were referred to the gastroenterology clinic and followed for one month. Finally, they were divided into two groups of cases with clear cause of abdominal pain and unclear cause of abdominal pain and patients' characteristics were compared between the groups. RESULTS 150 cases with the mean age of 40.68 ± 18.34 years were studied (53.3% female). After one month, 67 (44.7%) patients still complained of abdominal pain. A definitive cause of abdominal pain was established in 88 (58.7%) cases. There was not any significant difference between groups regarding, sex distribution (p = 012), duration of pain (p = 0.11), history of previous similar pain (p = 0.136), pain radiation (p = 0.737), length of hospital stay (p = 0.51), and presence of anorexia (p = 0.09), nausea and vomiting (p= 0.50), fever (p = 1.0), diarrhea (p = 0.23), and constipation (p = 0.07). There was a significant difference between the groups regarding location of pain (p = 0.017), age (p = 0.001) and history of comorbid diseases (p = 0.046). The predictive factors of finding a clear cause for abdominal pain in one-month follow-up, were leukocytosis (OR: 5.92 (95% CI: 2.62 - 13.39); p < 0.001), age (OR: 2.78 (95% CI: 1.15 - 6.71); p = 0.023), and outpatient follow-up (OR: 1.04 (95% CI: 1.02 - 1.07); p < 0.001). CONCLUSION Approximately, 40% of patients who were discharged with unspecified abdominal pain did not receive a clear diagnosis after one month of follow-up. Older age, leucocytosis in initial evaluations, and outpatient follow-up increased the probability of finding a clear cause for abdominal pain in the mentioned cases.

Safety and Efficacy of N-SORB ®, a Proprietary KD120 MEC Metabolically Activated Enzyme Formulation: A Randomized, Double-Blind, Placebo-Controlled Study. J Am Coll Nutr 2019; 38:577-585.

Abstract
Background: Enzymes are crucial for all aspects of metabolic function. Digestive enzymes from natural sources have been credited with beneficial effects in the digestion and absorption of food. N-SORB is a novel KD120 multienzyme complex (MEC) of metabolically activated enzymes composed of proteases, amylases, lipases, alpha-galactosidase, and glucoamylase from natural sources. These enzymes are encapsulated in a SK713 SLP (non-GMO soy lecithin phospholipid) absorption technology (Prodosome®). Objective: This randomized, double-blind placebo-controlled investigation assessed the safety and efficacy of N-SORB KD120 MEC in healthy male and female volunteers on various parameters of the blood, immunity, body composition, physical health, and quality of life following a 90-day intervention. Methods: Forty-six male and female (mean age: 25.8 ± 12.1 years) healthy volunteers were randomly assigned to receive either N-SORB (1 mL, twice daily) or placebo for 90 consecutive days. Complete blood count, as well as blood glucose, liver enzymes, and lipid profile were assessed pre- and post-intervention. Serum cytokine levels were determined by using a Bio-Plex Pro Human Cytokine 8-plex assay and enzyme linked immunosorbent assay (ELISA). Whole body composition analysis was performed by dual-energy x-ray absorptiometry (DEXA) to determine body fat mass, lean mass, and android and gynoid fat. Body weight, blood pressure, and physical health were assessed. Changes in quality of life were examined using the World Health Organization Quality of Life-abbreviated version and sleep quality was assessed using the 24-item Pittsburgh Sleep Quality Index (PSQI) questionnaire. Adverse events were monitored before, during, and after completion of the study. Results: Of the 46 subjects enrolled, a total of 40 subjects successfully completed the study. Compared to placebo, changes in blood cell counts including hematocrit, hemoglobin, mean corpuscular volume, platelets, and lymphocytes provide evidence of some improvement. Quality of life (QOL) parameters showed a small but significant improvement in the N-SORB group. A significant increase was observed in aspartate aminotransferase level in the placebo group at the end of 90 days of treatment; however, no increase was observed in the N-SORB group. No significant changes in blood urea nitrogen, serum creatinine, alkaline phosphatase, alanine aminotransferase, and lipid profile were observed between the placebo and treatment groups before and following intervention. No adverse effects were reported. Conclusions: This randomized, double blind, placebo-controlled clinical study demonstrates that short-term intervention with N-SORB improves the QOL and PSQI in healthy volunteers and did not significantly alter cardiometabolic parameters, lipid profile, or body composition.
