Metabolic and hormonal changes after laparoscopic sleeve gastrectomy in pediatric population: An observational study.

Introduction: Despite the growing popularity of laparoscopic sleeve gastrectomy (SG) for managing severe obesity in children, adolescents, and adults, there is a paucity of studies reporting the effects of SG on metabolic and hormonal outcomes in pediatric populations. Methodology: In this single-centre, retrospective study, we assessed nutritional biomarkers (hemoglobin, ferritin, iron profile, Vitamin B12, Vitamin D, and calcium), glucose homeostasis indicators (C-peptide, HbA1C, and random blood glucose), blood lipids (triglycerides and cholesterol components), hormones involved in the hypothalamic-pituitary-adrenal axis (cortisol and adrenocorticotropic hormone), and thyroid hormones (T3, T4, thyroid-stimulating hormone, and parathyroid hormone) preoperatively and 12-month after SG in children aged 5-15 years. Results: This study included 64 adolescents (mean age = 11.2 ± 2.3 years) who underwent laparoscopic SG. Significant reduction in circulatory C-peptide (-62.1%; p = 0.005), HbA1C (-10.9%; p = 0.001), random blood glucose (-15.4%; p = 0.036), and triglycerides (-39.4%; p = 0.003) were observed postoperatively at 12 months compared to baseline. Although we did not observe any changes in cortisol levels, adrenocorticotropic hormone levels declined significantly by -40.9% postoperatively (p = 0.033). However, cholesterol components, thyroid hormones, and nutritional biomarkers remained unchanged from baseline. Conclusions: Consistent with prior literature, our study demonstrates improvement or resolution of diabetes and hypertriglyceridemia in the year following SG. However, given that blood cholesterol components, nutritional biomarkers, and thyroid profiles remained unchanged warrants long-term monitoring of nutritional, metabolic, and endocrine factors in adolescents undergoing laparoscopic SG. To the best of our knowledge, this is the first study reporting the effects of SG on thyroid and hypothalamic-pituitary-adrenal axis hormones in pediatric populations.

Effect of Laparoscopic Sleeve Gastrectomy on HbA1C Level in Children with Type 2 Diabetes Mellitus.

Background and Objectives: A third of the American adult population is currently pre-diabetic/morbidly obese and is, therefore, at an elevated risk for developing type 2 diabetes. Unfortunately, such a condition does not spare children from also developing morbid obesity, where incidence rates of childhood obesity-coupled with type 2 diabetes-are markedly elevated. Laparoscopic sleeve gastrectomy (LSG) is gradually becoming the novel benchmark in bariatric surgery for the treatment of morbid obesity and associated co-morbidities, also within pediatric cases. However, no comprehensive study has been conducted in children that emphasizes the effect of LSG on HbA1C levels within such a patient population suffering from type 2 diabetes. Aim: Since HbA1C is a major biomarker for type 2 diabetes progression, this study aimed to identify any dysregulated serum levels for this key molecular player (together with other parameters), for post-surgical monitoring of the beneficial metabolic effects of LSG surgery on type 2 diabetes amelioration/remission within pediatric patients. Materials and Methods: A total of 64 pediatric patients, ranging in age from 5 to 14 years old, were enrolled in this retrospective study. Multiple laboratory-based analyses datasets were also collected from individual study participants, including HbA1C and random blood sugar (RBS). All participating patients were designated for undergoing laparoscopic sleeve gastrectomy, as per standardized surgical protocols and each participant was followed-up for two years post-surgery. Laboratory investigations were re-performed in order to identify any major variations in clinical parameters. Results: HbA1c was significantly reduced among children, from 6.0 ± 0.8 (pre-LSG) to 5.4 ± 0.4 post-surgery, with a reduction rate of 10.9% (p = 0.001). Furthermore, RBS significantly decreased from 102.9 ± 34.0 (pre-LSG) to 87.1 ± 17.3 post- surgery, with a reduction rate of 15.4% (p = 0.036). Conclusions: This study provides further concrete evidence for the beneficial metabolic influence provided by LSG surgery on morbidly obese, childhood-aged patient populations, with effectiveness in reducing co-morbidity progress, in the form of type 2 diabetes, through the reduction in HbA1c levels within such patients post-surgery.

Clinical Appropriateness of Serum Folate ordering pattern in a tertiary care hospital in Saudi Arabia.

Folate, also known as vitamin B9, is a co-factor necessary for DNA synthesis. Folate deficiency is associated mainly with hematological findings including megaloblastic anemia and pancytopenia. Many countries have mandated grain fortification with micronutrients including folic acid resulting in a reduced prevalence of folate deficiency. Saudi Arabia imports most of the grain products and folate is usually added after milling. There are no local studies to address the folate deficiency prevalence. In this study we aimed to analyse the clinical appropriateness of ordering practice of serum Folate level. METHOD: We reviewed all serum folate requests received at our laboratory in Aseer Central Hospital over one-year period (July 2018 June 2019). We collected patients' demographics from the electronic requests along with biochemical results of serum B12, ferritin and CBC results. We assessed appropriateness of orders against pre-specified criteria and applied statistical tests to explore for any association or significance. RESULTS: Serum folate requests from 614 patients were received during the study period. Serum B12 (543, 88%), and serum ferritin (511, 83%) were concurrently requested. The most common reason for request, when available, was anemia. Anemia was present in (313, 51%) of the subjects for which microcytic anemia was predominant (199, 63.5%), followed by normocytic anemia (101, 33%) and only 10 subjects had macrocytic anemia (3.2%). The most common hematinics' deficiency was ferritin (30%) followed by B12 (17.2%). Serum folate deficiency was low, observed in only 2.8%. Low folate levels were not significantly different between the group with anemia and the normal hemoglobin group. CONCLUSION: This study identifies a commonly inappropriate serum folate ordering practice that includes ordering all hematinics at the same visit without considering the possible anemia etiologies. The excessive requests might be related to doctors attempt to avoid multiple blood extractions and to try to reduce the time for diagnosis. These policies are generating unnecessary costs and time loss. Education, phasing out or restricting some tests and introducing laboratory policies like sample storing could help reduce unnecessary requests.

Diabetes-care practices and related awareness amongst type-2 diabetes patients attending diabetes OPD at a tertiary care hospital in southwestern Saudi Arabia.

BACKGROUND: Diabetes is the most prevalent disease in Saudi Arabia having vast health and economic implications. Hence, it is important that all measures must be undertaken to prevent and control the disease. OBJECTIVES: This study was performed to assess the diabetes-care practice and related awareness of patients of type 2 diabetes attending the outpatient department of a diabetes care center at a tertiary care hospital in southwestern Saudi Arabia. METHODS: A descriptive cross-sectional approach was used wherein patients attending the outpatient department of the diabetes treatment center of a tertiary hospital in the southern region of the Kingdom of Saudi Arabia were surveyed, using a predesigned pretested questionnaire covering the study variables. RESULTS: The study included 287 individuals with type 2 diabetes in the age range 25 years to 90 years (mean age = 55.5 years). Around 57% of the participants were females while the rest were males. CONCLUSION: The present study showed that awareness about diabetic complications among the study population is good, especially among young educated patients who adhere to regular medical follow-up. Attending physicians were a major source of awareness for the patients.
