Effect of physical training on motor function of ambulant children with diplegia after selective dorsal rhizotomy: A randomized controlled study.

BACKGROUND: Children with spastic diplegia experience tonicity, lack of selective motor control, subnormal postural stability and delayed motor development. Selective dorsal rhizotomy followed by physical therapy is a permanent procedure aimed to alleviate hypertonicity. OBJECTIVE: To explore the efficacy of selective dorsal rhizotomy (SDR) followed by a physical training on gross motor function (GMF), functional balance, walking capacity, selective motor control (SMC) and energy cost of walking (ECW) of ambulant children with spastic diplegia. METHODS: Forty-two children with spastic diplegia aged 5 to 8 years were randomly assigned into the control or SDR-group. Both groups received a designed physical training of progressive functional strength training and standard orthotic management (SOM) 3 times a week for 6 months. GMF, functional balance, ECW, functional capacity and SMC were assessed by gross motor function measure (GMfM-88), pediatric balance scale (PBS), energy expenditure index (EEI), six-minute walking test (6MWT) and selective control assessment of lower extremity (SCALE), respectively. Assessment was carried out before the treatment (baseline), after 6 months (post I) and 1-year follow-up (post II). RESULTS: From baseline to post I and post II assessments, changes of GMF, functional balance, ECW, functional capacity and SMC within the control and SDR groups showed significant improvements (P < 0.001). Moreover, group comparison showed significant differences in favor of the SDR group. CONCLUSION: Integrated physical training followed SDR demonstrated qualitative changes and enhancement in motor function, achieved by spasticity reduction.

Aerobic exercise with diet induces hormonal, metabolic, and psychological changes in postmenopausal obese women.

Physical activity and diet are recommended lifestyle strategies to improve human health. Consequently, this study aimed to investigate the impact of aerobic exercise combined with dietary restriction on hormonal, metabolic, and psychological variables in postmenopausal women. Eligible 60 women were enrolled and assigned into two equal groups; the experimental group performed aerobic exercise three times per week for 12 weeks with diet restriction, and the control group only received the same diet program. Serum levels of sex hormones, insulin resistance, and depression scores were measured before and after the intervention. Results: All measured variables were significantly changed in the experimental group compared to the control group (P = 0.001). Conclusion: Changes in sex hormones are a biological marker of metabolic complications such as insulin resistance, which can be reduced with exercise and diet. In addition, they are effective therapeutic interventions in the treatment of mild depression. Trial registration: Registration identifier number of this study is: NCT05136742 on https://register.ClinicalTrials.gov.

Aerobic Exercise with Mediterranean-DASH Intervention for Neurodegenerative Delay Diet Promotes Brain Cells' Longevity despite Sex Hormone Deficiency in Postmenopausal Women: A Randomized Controlled Trial.

Objective: To investigate the combined impact of aerobic exercise and Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet on brain cells longevity in spite of sex hormones deficiency in obese postmenopausal women. Design: A parallel randomized clinical trial. Subjects/Patients. Sixty-eight eligible postmenopausal women were randomly assigned to one of two groups, one experimental and one control. The participants' age ranged from 60 to 75 years, and their body mass index ranged from 30 to 39.9 kg/m2. Methods: An experimental group whose members followed moderate-intensity treadmill exercise three times/week for three months with MIND diet and a control group whose members followed the MIND diet only. In addition to serum sex hormones, pre- and post-12-week assessments were performed to measure serum sex hormones as well as cognitive and functional levels. Results: The experimental group showed after intervention highly significant changes (p < 0.01) in sex hormones, cognitive functions, and functional levels compared with the control group (p < 0.05). In addition, no correlation was found between the measured variables in both groups after intervention (p > 0.05). Conclusion: Aerobic exercise combined with the MIND diet improves cognitive and functional levels and substitutes sex hormones deficiency in postmenopausal women, which affects the longevity of brain health.

Predictors of type-2 diabetes remission following bariatric surgery after a two-year follow-up.

PURPOSE: Bariatric surgery is evolving as a successful tool for managing morbid obesity and T2DM. This study aimed to identify predictors of diabetes remission after two types of bariatric procedures. METHODS: This prospective study enrolled 172 patients with morbid obesity associated with T2DM scheduled for bariatric surgery. Two laparoscopic bariatric procedures were done; single anastomosis gastric bypass (SAGB, n = 83) and sleeve gastrectomy (LSG, n = 68). Lipid accumulation product index (LAP) and quantitative insulin sensitivity check index (QUICKI) were used to evaluate lipid profile and insulin sensitivity. Two years after surgery condition of DM was evaluated as complete remission (CR), partial remission (PR), or improvement. The primary outcome measure was predictors of diabetes remission. RESULTS: Two years after surgery, 151 patients were available for evaluation, where 75 patients (49.7%) achieved CR, while PR was found in 36 (23.8%). CR was significantly associated with younger age, shorter duration of DM (p < 0.001, for both), higher C-peptide and GLP-1 levels (p < 0.001 and p = 0.002, respectively), and bypass surgery (p = 0.027). On multivariate analysis, shorter duration of DM, lower BMI, and higher C-peptide levels were the independent factors predicting CR. CONCLUSION: Complete remission of T2DM can be achieved in nearly half of the patients two years after SG or SAGB. The duration of diabetes and preoperative BMI and C-peptide levels are the independent factors predicting complete remissions.

Secondary Hyperparathyroidism Before and After Bariatric Surgery: a Prospective Study with 2-Year Follow-Up.

PURPOSE: Secondary hyperparathyroidism (SHPT) is linked to obesity. Bariatric surgery may be associated with calcium and vitamin D deficiencies leading to SHPT. This study aimed to detect the prevalence of SHPT before and after bariatric surgery. METHODS: This prospective study assessed the prevalence of SHPT after sleeve gastrectomy (SG, n = 38) compared to one-anastomosis gastric bypass (OAGB, n = 86). All patients were followed up for 2 years. Bone mineral density (BMD) was assessed using dual-energy X-ray absorptiometry. RESULTS: Of the 124 patients, 71 (57.3%) were females, and 53 (42.7%) were males, with a mean age of 37.5 ± 8.8 years. Before surgery, 23 patients (18.5%) suffered from SHPT, and 40 (32.3%) had vitamin D deficiency. The prevalence of SHPT increased to 29.8% after 1 year and 36.3% after 2 years. SHPT was associated with lower levels of vitamin D and calcium and higher reduction of BMD in the hip but not in the spine. After 2 years, SHPT was associated with a significantly lower T-score in the hip. SHPT and vitamin D deficiency were significantly more common in patients subjected to OAGB compared to SG (p = 0.003, and p < 0.001, respectively). There is a strong negative correlation between vitamin D levels and parathormone levels before and after surgery. CONCLUSION: Prevalence of SHPT is high in obese patients seeking bariatric surgery, especially with lower vitamin D levels. Bariatric surgery increases the prevalence of SHPT up to 2 years. Gastric bypass is associated with a higher risk of developing SHPT compared to SG.

Antithyroid Peroxidase Antibodies and Histopathological Outcomes in Egyptian Patients Subjected to Total Thyroidectomy for Non-Malignant Nodular Goiter.

OBJECTIVE: The study aimed to assess antithyroid antibodies in patients with benign thyroid masses and the effect of total thyroidectomy on the antibodies titers. PATIENTS AND METHODS: This is a retrospective work of 112 cases managed with total thyroidectomy with positive antithyroid peroxidase antibodies (TPO-Ab), anti-thyroglobulin antibodies (Tg-Ab), or both. All patients were euthyroid before surgery. Thyroid function tests and thyroid antibodies levels were measured before and 6 and 12 months after surgery. RESULTS: Histopathological evaluation revealed Hashimoto thyroiditis (47.3%), colloid nodules (22.3%), and lymphocytic thyroiditis (30.4%). All patients were TPO-Ab positive, while 96 patients (85.7%) were Tg-Ab positive before surgery. There was no considerable change in TPO-Ab and Tg-Ab after surgery (p = 0.817, and p=0.560, respectively). Also, there was no significant difference between the three histopathological diagnoses in the levels of TPO-Ab (p = 0.086) or Tg-Ab (p = 0.673). CONCLUSION: Antithyroid antibodies are not valuable markers for diagnosis or prognosis of benign thyroid diseases subjected to total thyroidectomy. We do not recommend their use beyond supporting evidence of the possibility of the autoimmune nature of the illness if other criteria are confirmed.

Laparoscopic Sleeve Gastrectomy has A Positive Impact on Subclinical Hypothyroidism Among Obese Patients: A Prospective Study.

BACKGROUND: The effect of bariatric surgery on postoperative thyroid function remains incompletely understood. In this study, we aimed to evaluate the changes in thyroid functions after gastric sleeve operation for morbidly obese Egyptian patients. METHODS: This was a prospective study that recruited 128 patients who underwent sleeve gastrectomy through the period from December 2016 to April 2020. We measured thyroid-stimulating hormone (TSH), free thyroxin (FT4), and free triiodothyronine. Subclinical hypothyroidism was defined by a TSH level > 4.5 mIU/L but a normal FT4 level. All patients were followed for 12 months after the procedure. RESULTS: Preoperatively, 30 (23.4%) patients had subclinical hypothyroidism. The prevalence of subclinical hypothyroidism decreased significantly to reach 7.8% at the end of follow-up (p < 0.001). None of the patients developed de novo hypothyroidism at the end of follow-up. Patients with subclinical hypothyroidism were more likely to be females (p = 0.037) and had significantly higher waist circumference (p < 0.001), DBP (p = 0.02), serum cholesterol (p < 0.001), and serum triglyceride (p < 0.001). However, patients with subclinical hypothyroidism at the end of follow-up had significantly higher BMI at the end of the sixth month (p = 0.048). Similarly, patients with subclinical hypothyroidism at the end of follow-up had significantly higher serum cholesterol (p = 0.002), LDL, (p = 0.038), and serum triglyceride (p < 0.001) at the end of the sixth months of follow-up. A similar trend was noted at the end of the 12th month. The preoperative value of serum TSH correlated significantly with serum cholesterol and triglyceride levels. CONCLUSION: The positive effect of the LSG procedure on the hypothyroid bariatric population, including enhanced thyroid function, was demonstrated.

Factors associated with resolution of type-2 diabetes mellitus after sleeve gastrectomy in obese adults.

Many bariatric procedures are more effective for improving type-2 diabetes mellitus (T2DM) than conventional pharmacotherapy. The current research evaluated factors linked to complete and partial remission or improvement of T2DM after laparoscopic sleeve gastrectomy (LSG). The current prospective study included all diabetic patients who were submitted LSG between January 2015 and June 2018 and completed a 2-year follow-up period. Patients were assessed at baseline and 2 years after LSG. This work comprised of 226 diabetic cases. Two years after LSG, 86 patients (38.1%) achieved complete remission of DM, and 24 (10.6%) reached partial remission. Only 14 patients (6.2%) showed no change in their diabetic status. On univariate analysis, age ≤ 45 years, duration of diabetes ≤ 5 years, use of a single oral antidiabetic, HbA1c ≤ 6.5%, HOMA-IR ≤ 4.6, C-peptide > 2.72 ng/mL, and BMI ≤ 40 kg/m2 predicted complete remission. The independent predictors of complete remission were age ≤ 45 years, duration of diabetes ≤ 5 years, use of a single oral antidiabetic, HOMA-IR ≤ 4.6, and C-peptide > 2.72 ng/mL. A combined marker of young age, short duration of DM, and low HOMA-IR predicted complete remission with sensitivity 93% and specificity 82%. Independent predictors of complete remission of T2DM after LSG were younger age, shorter duration, single oral antidiabetic, lower HOMA-IR, and higher C-peptide.

Urinary pigment epithelium-derived factor as a marker of diabetic nephropathy in Egyptian patients with type 2 diabetes mellitus.

Diabetic nephropathy (DN) is the most common cause of end-stage renal disease. Urinary pigment epithelium-derived factor (PEDF) has also been shown to suppress the expression of fibrogenic, pro-inflammatory, and angiogenic factors, thus contributing to pathological changes in early DN. We aimed to study the role of urinary PEDF as a biomarker for the detection of chronic kidney disease progression in patients with type 2 diabetes mellitus (T2DM). Sixty patients with T2DM were recruited in addition to 20 nondiabetic healthy volunteers. Urinary PEDF using enzyme-linked immunoassay technique was performed to all subjects, and correlations between it and different clinical parameters were examined. Our study showed a statistically significant correlation between urinary PEDF level and duration of DM (P <0.001), glycosylated hemoglobin (P <0.001), serum creatinine (P <0.001), urinary albumin-to-creatinine ratio (P <0.001), and stage of diabetic retinopathy by fundus examination (P <0.001). Urinary PEDF is a good indicator of progression of DN and microvascular damage (as a complication of diabetes) in general. It was also increased in case of poor diabetic control.

Role of vitamin D supplements in prevention of hungry bone syndrome after successful parathyroidectomy for primary hyperparathyroidism: A prospective study.

BACKGROUND: We postulated that the preoperative correction of vitamin D levels can significantly reduce the incidence of hunger bone syndrome among patients undergoing parathyroidectomy for primary hyperparathyroidism. METHODS: We performed a prospective, randomized, open-label study on 102 patients with primary hyperparathyroidism and coexisting vitamin D deficiency who were scheduled to undergo parathyroidectomy. Patients were divided into the following two groups: group I which included 52 patients who did not receive preoperative vitamin D supplementation; and group II which included 50 patients who received cholecalciferol 1000-2000 IU daily or 50000 IU weekly until they achieve vitamin D levels >20 ng/mL (group IIa = 25 patients) or vitamin D levels >30 ng/mL (group IIb = 25 patients). RESULTS: The incidence of hunger bone syndrome in group IIb was lower than group I and group IIa (8% versus 16% versus 23%, respectively); however, this difference did not reach the level of statistical significance (p = 0.22). Patients with hunger bone syndrome were significantly younger and had higher serum phosphorus, alkaline phosphatase, magnesium, and bone mineral density at baseline than patients without hunger bone syndrome. On the other hand, patients with hunger bone syndrome had significantly lower 25-hydroxyvitamin D at baseline than patients without hunger bone syndrome (p = 0.001). The ROC curve showed that the baseline level of serum 25-hydroxyvitamin D was not an independent discriminator of hunger bone syndrome (area under curve = 0.21 (95% CI: 0.06-0.34); p = 0.011). CONCLUSIONS: Preoperative course of vitamin D supplements has no preventive role on the postoperative incidence of hunger bone syndrome among patients with primary hyperparathyroidism and coexisting vitamin D deficiency undergoing parathyroidectomy.

Impact of sustained virological response on metabolic disorders in diabetic chronic hepatitis C virus patients after treatment with generic sofosbuvir and daclatasvir.

OBJECTIVES: To evaluate the effect of generic sofosbuvir and daclatasvir (SOF/DCV) treatment on the glycemic state and insulin resistance as well as lipid profiles of those who achieved sustained virological response (SVR) in diabetic chronic hepatitis C virus (CHC) patients. METHODS: We retrospectively reviewed 114 CHC patients with evidence of type 2 diabetes that were treated with generic SOF/DCV between May 2016 and August 2017. Baseline demographic and laboratory data were recorded. At 12-week post end of therapy (SVR12), glycemic state and insulin resistance as well as lipid profiles were re-evaluated and compared with baseline. RESULTS: A total of 98 diabetic CHC patients were finally included and were responders. A significant decline in the glycemic state as well as Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) values (P ≤ 0.0001) was observed, but HOMA-S showed a statistically significant increase (P ≤ 0.0001) at SVR12 in comparison to baseline values. Also, a significant increase in serum total cholesterol, low-density lipoprotein (LDL)-cholesterol, and high-density lipoprotein (HDL)-cholesterol levels was observed at SVR12 compared to baseline, but serum triglycerides levels showed a significant decrease. Logistic regression showed that the higher baseline HOMA-IR was a significant predictive variable of a decrease ≥20% of HOMA-IR, while higher baseline HOMA-IR and baseline triglycerides emerged as the only significant predictors of the Δ increase LDL-C level at SVR12. CONCLUSION: SOF/DCV-based therapy led to an improvement of glycemic state associated with a global worsening of lipid profile. Further studies are strongly warranted to evaluate the cardiovascular balance between amelioration of insulin resistance and negative changes of the lipid profile.

Effect of branched chain amino acid supplementation on dialysis adequacy and nutritional parameters in hemodialysis patients.

Malnutrition in hemodialysis (HD) patients is caused by deficient nutrient and protein intake and has a negative impact on patient outcomes. The assessment of dialysis adequacy in these patients depends to a large extent on the calculation of urea clearance using dialyzer clearance of urea (K) multiplied by the duration of the dialysis treatment (t, in minutes) divided by the volume of distribution of urea in the body (V, in mL); Kt/V. This study aims to detect the effect of branched-chain amino acid (BCAA) supplementation on Kt/V and other nutritional parameters such as serum albumin as well as body mass index. Forty-six patients from the HD Unit of Mostafa Mahmoud Hospital were included in this study. Daily intake of BCAA was continued for three months. At the start of the study, before the intervention, and at the end of the 3rd month, we measured serum albumin, valine, leucine, iso-leucine, and Kt/V. Analysis of data was performed using paired and independent t-test. We found that BCAA has a highly significant effect on increasing the level of albumin, leucine, isoleucine, valine, and Kt/V in HD patients (P <0.001) (Paired t-test). BCAA supplements could be used in this patient population to improve dialysis adequacy and outcome.

Serum Serotonin as a Potential Diagnostic Marker for Hepatocellular Carcinoma.

To assess the potential role of serum serotonin level in hepatocellular carcinoma (HCC) diagnosis. A case-control study that involved 100 Egyptian adults. Subjects were divided into 4 groups: Group I: 21 patients with late-stage HCC on top of liver cirrhosis, Group II: 28 patients with early-stage HCC on top of liver cirrhosis, Group III: 26 patients with cirrhosis with no evidence of HCC, and Group IV: 25 healthy age- and sex-matched subjects were as a control group. Serum serotonin level was determined in all recruited subjects using high-performance liquid chromatography-fluorescent detection method. Alpha-fetoprotein had a statistically significant elevation in group I with a median of 1300 ng/L (195-2544 ng/L) compared to groups II and III (P ≤ 0.01). Regarding serum serotonin level, it had a statistically significant elevation in group II with a median of 275 ng/µL (204.7-400 ng/µL) compared to groups I, III, and IV with median of 33 ng/µL (30-50 ng/µL), 50 ng/µL (30-60 ng/µL), and 102 (85-150 ng/µL), respectively (P = 0.001). Receiver operating characteristic curve showed that serum serotonin at cutoff value of 108 ng/µL had a sensitivity of 100% and specificity of 92.3% in discriminating early-stage HCC from cirrhosis. Serum serotonin level is a rapid, sensitive, noninvasive diagnostic biomarker for the detection of early-stage HCC.
