ABSTRACT

CONTEXT: Gestational diabetes mellitus (GDM) is a complex obstetric condition affecting localized glucose metabolism, resulting in systemic metabolic dysfunction. OBJECTIVE: This cross-sectional study aimed to explore visceral adipose tissue (VAT) as an integral contributor to GDM, focusing on elucidating the specific contribution of obesity and GDM pathology to maternal outcomes. METHODS: Fifty-six nulliparous pregnant women were recruited, including normal glucose tolerant (NGT) (n = 30) and GDM (n = 26) participants. Participants were subgrouped as nonobese (BMI <30 kg/m2) or obese (BMI ≥30 kg/m2). Metabolic markers in circulation, VAT, and placenta were determined. Morphological analysis of VAT and immunoblotting of the insulin signaling cascade were performed. RESULTS: GDM participants demonstrated hyperinsulinemia and elevated homeostatic model assessment for insulin resistance (HOMA-IR) scores relative to NGT participants. The GDM-obese subgroup had significant VAT adipocyte hypoplasia relative to NGT-nonobese tissue. GDM-obese VAT had significantly lower insulin receptor substrate (IRS)-2 expression, with elevated ser312 phosphorylation of IRS-1, relative to NGT-nonobese. GDM-obese participants had significantly elevated circulating leptin levels and placental adipsin secretion, while GDM-nonobese participants had elevated circulating adipsin levels with reduced placental adiponectin secretion. CONCLUSION: These findings suggest that GDM-obese pregnancy is specifically characterized by inadequate VAT remodeling and dysfunctional molecular signaling, which contribute to insulin resistance and hinder metabolic health.

ABSTRACT

PURPOSE: UK guidelines recommend an HbA1c < 8.5% prior to elective surgery. Optimisation of pre-operative glycaemic control can be often difficult. Aim to correlate the effect of pre-operative HbA1c on the peri-operative complication rates and whether elective bariatric surgery should be delayed in poorly controlled diabetics. MATERIAL AND METHODS: Retrospective data of consecutive patients who underwent laparoscopic Roux-en-Y gastric bypass, one-anastomosis gastric bypass and laparoscopic sleeve gastrectomy during January 2014 and April 2018. Patients were categorised into group 1, non-diabetics with an HbA1c < 6.5%; group 2, well-controlled diabetics with HbA1c between 6.5 and 8.4%; and group 3, poorly controlled diabetics with HbA1c ≥ 8.5%. Primary outcome was peri-operative complication rates. RESULTS: Group 1 (n = 978), 81.8% female, median (i.q.r.) age 44.0 (34-52) years, median (i.q.r.) BMI 42.0 (38.7-46.7); group 2 (n = 350), 66.3% female, age 51.0 (45-59) years, BMI 41.8 (37.5-46.5); and group 3 (n = 90), 60% female, age 52.0 (45-56) years and BMI 41.4(36.9-44.8). Early complication rates in each group were low, 1.0% vs 1.7% vs 1.1% (p = 0.592). Mean length of stay was 2 days across the groups (p > 0.05). There was no difference in 30-day re-admission rates between groups 2.8%, 2.9% and 3.3% (p = 0.983). At 6 months and 1 year, there was sustained and equal reduction in HbA1c in all groups (p < 0.05). CONCLUSION: Patients undergoing metabolic surgery for poorly controlled diabetes achieve non-inferior peri-operative outcomes. Hence, delaying metabolic surgery in an attempt to optimise diabetic control is not justifiable.

ABSTRACT

BACKGROUND: Mixed connective tissue disease (MCTD) is a rare autoimmune disease, characterized by the production of specific autoantibody anti-RNP, which presents with varied overlapping symptoms of different connective tissue disorders. The aim of this study is to identify the frequency and patterns of MCTD. METHODS: This is a descriptive cross-sectional hospital-based study conducted at the rheumatology clinic at Omdurman Military Hospital between February 2019 and July 2019. The study included 30 patients and data were collected using a designated questionnaire. RESULTS: The study showed that the majority of patients (96.7%) were females and only 3.3% was male. About 30% of the patients aged between 30 and 39 years were the most affected. As a first diagnosis, 10% of the patients had a MCTD fulfilling the Alarcon-Segovia criteria. The remaining 90% of the patients were diagnosed with other diseases before evolving into MCTD. The most common clinical presentation was arthralgia in 100% of the patients, 90% were symmetrically followed by myositis in 70% of the patients, arthritis in 63.3% of the patients, puffy fingers in 63.3% of the patients, and hand swelling in 60% as major musculoskeletal symptoms. Regarding the initial results in immunological profile, the most common positive autoantibodies among the patients were anti-RNP titer in 96.7% of the patients, ANA in 90%, anti-Sm in 50%, RF in 50%, anti-Ds DNA in 46.7%, and anti-Ro in 43.3%. CONCLUSION: This study showed that MCTD is more common in females, only 10% of patients presented with a fulfilling criteria of the disease at diagnosis, and the rest of the patients presented with other rheumatologic diseases before evolving into MCTD.

ABSTRACT

INTRODUCTION: Anastomotic leak (AL) after right hemicolectomy remains a significant clinical challenge with an incidence of 4.2% to 8.2% in European series. Near infrared imaging with indocyanine green (NIR-ICG) allows real-time assessment of bowel perfusion. However, there is a lack of published data assessing the clinical utility of this new technology in right sided colonic resection. MATERIALS AND METHODS: Data from electronic records were retrospectively analyzed for consecutive patients undergoing right hemicolectomy in a single center between March 1, 2016 and October 31, 2019. Primary outcomes were the incidence of AL and the frequency with which ICG-NIR imaging altered the intraoperative course. RESULTS: Our study included 127 patients, with 65 in the NIR-ICG group and 62 in the control group. Median length of follow-up was 24 months. There was no significant difference in demographic or pathologic characteristics between the 2 cohorts. There was no significant difference in operation length between the NIR-ICG and control groups (164.7 vs. 162.9 min, P=0.88). The use of NIR-ICG altered the intraoperative course in 4/65 (6.2%) patients. The rate of AL was lower in the NIR-ICG group (1.5% vs. 4.8%), although this did not reach statistical significance. CONCLUSION: The use of NIR-ICG altered the intraoperative course for notable subset of patients undergoing right hemicolectomy without prolonging operative time. Larger prospective studies are required to evaluate the potential for the routine use of this technology to reduce AL rate in right hemicolectomy.

ABSTRACT

INTRODUCTION: Most Bariatric units perform Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) and One Anastomosis Gastric Bypass (OAGB) for weight loss and metabolic purposes with satisfactory results and low complication profile. OBJECTIVES: This study compares LRYGB and OAGB outcomes in a high volume single bariatric unit. METHODS: Data was collected prospectively and analysed retrospectively for all LRYGB and OAGB performed between Jan 2014 to Dec 2016. The follow up period was for 2 years. Patients who were lost to follow up or had prior bariatric procedure were excluded. Excess weight loss percentage (EWL %), total weight loss percentage (TWL %) and post-operative complications were compared in both groups. RESULTS: 1268 procedures performed. 113 patients were excluded. At 2 years, for LRYGB and OAGB groups mean TWL % was 31% and 35.4% respectively (P < 0.0001); and mean EWL % was 70.1% and 74.8% respectively (P = 0.0119). Gastroesophageal reflux symptoms were higher in OAGB group 17 (8.5%), with 7 patients needing further surgery, versus 26 (2.7%) in LRYGB (P = 0.0003). There was no difference in incidence of marginal ulcers between LRYGB and OAGB 2.7% vs 5% respectively (P = 0.1115). Internal hernia was seen only in LRYGB patients, 22 (2.2%). There was no significant difference in the re-operation rates following LRYGB 52 (5.4%) and OAGB 16 (8%) (P = 0.1824). CONCLUSION: OAGB had superior short-term weight loss and low complications profile. Both procedures demonstrated no difference in either marginal ulcers or re-operation rates. Reflux symptoms have remained a major side effect of OAGB.
