In this article, examine the performance of a physics informed neural networks (PINN) intelligent approach for predicting the solution of non-linear Lorenz differential equations. The main focus resides in the realm of leveraging unsupervised machine learning for the prediction of the Lorenz differential equation associated particle swarm optimization (PSO) hybridization with the neural networks algorithm (NNA) as ANN-PSO-NNA. In particular embark on a comprehensive comparative analysis employing the Lorenz differential equation for proposed approach as test case. The nonlinear Lorenz differential equations stand as a quintessential chaotic system, widely utilized in scientific investigations and behavior of dynamics system. The validation of physics informed neural network (PINN) methodology expands to via multiple independent runs, allowing evaluating the performance of the proposed ANN-PSO-NNA algorithms. Additionally, explore into a comprehensive statistical analysis inclusive metrics including minimum (min), maximum (max), average, standard deviation (S.D) values, and mean squared error (MSE). This evaluation provides found observation into the adeptness of proposed AN-PSO-NNA hybridization approach across multiple runs, ultimately improving the understanding of its utility and efficiency.
Background: Bladder urothelial carcinoma is an alarming urologic malignancy. Complex factors like modelling and local staging can affect treatment strategy. However, local staging, particularly the muscle invasion status, significantly influences decisions regarding treatment strategies. Therefore, this study aims to evaluate the novel advances of three-dimensional (3D) ultrasound (US) imaging to assess local staging in comparison with conventional cystoscopy. Methods: Forty-three patients with painless haematuria and conventional cystoscopy findings of bladder mass underwent 3D US virtual cystoscopy. All specimens from conventional cystoscopy were processed histologically. Results: Out of 43 participants, 18 (41.9%) patients proved to have invasive urothelial carcinoma by histopathology. The 3D US had a sensitivity of 97.5% and a specificity of 100%; however conventional cystoscopy was accurate in only 53.5% of the studied cases. Furthermore, in the case of malignant ulcers, mural extension into both the submucosal and the muscle layers was more readily appreciated in multiplanar images. Conclusion: 3D US updates are promising for use in bladder tumour modelling and local staging; however, they can be of value in evaluating mural and extramural tumour extent and have proven accuracy.
Background and Objectives: Migraine is caused by genetic susceptibility that is triggered by environmental as well as biological factors, and it is also linked to many somatic comorbidities, including clinical and subclinical hypothyroidism. We aimed to estimate the potential association between subclinical hypothyroidism (ScH) and migraine in children at our tertiary hospital. Materials and Methods: Using a case−control strategy, 200 children and adolescents were assigned to two equal groups: a case group (patients with migraine) of 100 patients and a control group of 100 patients without migraine. Clinical and biochemical parameters (TSH, FT4) were compared between the groups using statistical analysis. Results: Thyroid function comparison between the groups showed higher TSH but normal FT4 among children with migraine headache compared to the control group, which means more frequent ScH cases among the migraine group relative to the control (17% vs. 2%, p < 0.001). Obesity and overweight were more frequent among patients with migraine than the control group (8 and 5% vs. 2 and 1%, respectively). The (overweight/obese) patients with migraine had about 77% ScH and 15.4% overt hypothyroidism compared to 8% ScH and no overt hypothyroidism among normal body weight migraine patients (p < 0.001). No significant difference in the prevalence of nodular goiter between patients with migraine and controls was found. Conclusions: Based on our results, subclinical hypothyroidism is significantly linked to childhood migraine. Obesity and being overweight are more frequent among patients with migraine. Therefore, it may be logical to test the thyroid function in migraineur children, especially those with high BMI. Further studies are recommended to discover the mechanism of this association in children.

We are trying to illustrate operative, short-term, and pathological outcomes of transanal total mesorectal excision (TaTME) as a surgical procedure for patients who are suffering cancer in the lower or middle rectum. This study included 25 consecutive patients who underwent TaTME for the mid and low cancer rectum. The primary outcome measures included frequency of postoperative (PO) bleeding, leakage, ileus, days to regain bowel function, days for Foley's removal, and erectile function. The secondary outcome measures included operation time, status of resection margins, number, the quality of TME, and duration PO hospital stay. No recorded intraoperative complications. The mean hospital stay was 6.9 ± 2.6 days. The mean duration need for urinary catheter removal and flatus passage were 2.4 ± 2.1 and 1.5 + 0.9 days, respectively. The mean IPSS was returned to normal 12 months after surgery. The mean distal margin distance was 1.9 ± 1.1. Circumferential margin distance was > 1 mm in 23 (92%) patients. The mesorectum was complete in 22 (88%) patients. The survival rate was 88% over 3 years. TaTME could be considered as a safe, feasible, and effective surgical modality for patients who had mid and lower rectal tumors with an excellent pathological outcome.
OBJECTIVE: We are trying to investigate the possibility, safety, and benefits of replacing the role of T-tube by another more safe and effective procedure for biliary decompression in the case of common bile duct (CBD) exploration. METHODS: Our present study includes fifty consecutive patients who underwent a traditional CBD exploration due to choledocholithiasis. Patients were divided into 2 equal groups. In the 1st group, a spontaneously expelled Nelaton tube is placed in the CBD to aid in bile drainage to the duodenum, while in the 2nd group, a conventional T-tube is placed to decompress the CBD in the early postoperative (PO) days to a drainage bag. Operative and PO data as well as PO hospital stay time were recorded. All data were collected and statistically analyzed. RESULTS: The mean operative time and PO hospital stay days were significantly low (p value < 0.05) in the Nelaton tube drainage group compared with the T-tube drainage group. On the other hand, the mean time needed for the abdominal drain removal was significantly higher in the T-tube drainage group (p value < 0.05). CONCLUSION: Nelaton tube with internal biliary drainage is effective and safer than T-tube drainage and it helps in reduction of the PO hospital stay time. In addition, it avoids all short-term complications of T-tube.
