Specifically, the study seeks to compare the incidence of proteinuria in patients undergoing radical nephrectomy and those receiving partial nephrectomy, thereby contributing valuable insights into post-surgical outcomes that could inform treatment approaches and improve patient care. Methods It is a retrospective cohort design, analyzing clinical data from patients who underwent radical or partial nephrectomy in King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia, between 2014 and 2022.

Leveraging transfer learning-driven convolutional neural network-based semantic segmentation model for medical image analysis using MRI images.

Recognition and segmentation of brain tumours (BT) using MR images are valuable and tedious processes in the healthcare industry. Earlier diagnosis and localization of BT provide timely options to select effective treatment plans for the doctors and can save lives. BT segmentation from Magnetic Resonance Images (MRI) is considered a big challenge owing to the difficulty of BT tissues, and segmenting them from the healthier tissue is challenging when manual segmentation is done through radiologists.

Effect of telerehabilitation assessment for adults with musculoskeletal conditions on access to care beyond the COVID-19 pandemic: A retrospective case-control analysis.

Background: Applying to periodontics programs in Saudi Arabia holds significant importance for both applicants and periodontics program directors. As of today, there has been no investigation into how periodontics program directors (PDs) identify and select potential candidates for their programs. The aim of this study is to assess the factors taken into consideration during the selection process for periodontics programs by PDs in Saudi Arabia.

Computational insights of double perovskite NaCaCdH hydride alloy for hydrogen storage applications: a DFT investigation.

Prospective use of perovskite hydride materials in H storage a crucial element of clean energy systems has drawn a lot of attention. The structural, electrical, mechanical, thermodynamic, and H storage qualities of NaCaCdH hydride alloys were examined in this work using DFT. According to the structural properties, NaCaCdH has space group 225 (Fm3m), and optimized lattice parameters and volume of NaCaCdH are 3.

Early Congenital Syphilis Presenting With Severe Congenital Pneumonia and Cutaneous Manifestations in a Neonate at Birth: A Case Report.

Transplacental transmission of spirochetes from an infected mother to the fetus during pregnancy results in the infectious condition known as congenital syphilis (CS). Once a forgotten disease, CS has now re-emerged. We report the clinical case of an early CS in a neonate girl presented with severe congenital pneumonia (pneumonia alba) requiring intubation, along with skin lesions that were visible from birth on the palms and soles of the feet.

In-plane thermal conductivity measurements of Si μ-cantilevers using the suspended thermo-reflectance (STR) technique.

The Suspended Thermoreflectance (STR) technique is described in this paper. This optoelectronic measurement tool performs thermal characterization of freestanding micro-/nanoscale materials. STR performs thermal mapping at the submicron level and produces unconstrained thermal conductivity unlike other optical measurement techniques where independent conductivity measurement is not possible due to their reliance on heat capacity.

Carrying angle among young adults of Saudi Arabia and its correlation with demographic characteristics: A cross sectional study.

Background: The angle between the median axes of the forearm and arm is called the carrying angle (CA). Sex differences in CA and its relation to age, height, weight, and BMI are unclear. The aim of the present study was to measure the CA in male and female subjects in the Saudi population and correlate it with the above variables.

Leveraging electrocardiography signals for deep learning-driven cardiovascular disease classification model.

Electrocardiography (ECG) is the most non-invasive diagnostic tool for cardiovascular diseases (CVDs). Automatic analysis of ECG signals assists in accurately and rapidly detecting life-threatening arrhythmias like atrioventricular blockage, atrial fibrillation, ventricular tachycardia, etc. The ECG recognition models need to utilize algorithms to detect various kinds of waveforms in the ECG and identify complicated relationships over time.
