The influence of transcatheter aortic valve replacement on left atrial mechanics: a systematic review and meta-analysis.

Aims: The morphology and function of the left atrium (LA) are intimately tied to left ventricular loading conditions. Data pertaining to the effect of transcatheter aortic valve replacement (TAVR) on LA function and geometry are scarce. The aim of the study was to quantify associations between TAVR and LA remodelling by pooling available data from published observational studies.

Mapping of uncontrolled dumpsites in arid regions through remote sensing and image processing.

Due to increased urbanization, the development of new areas, construction of new houses and buildings and uncontrolled dumpsites (UDSs) are becoming a challenge facing local authorities in Saudi Arabia. UDSs pose health risks to the public, potentially deteriorating the environment around them and reducing the value of ongoing development areas. The local municipalities rely on field surveys and citizen reports.

Assessment of Antibacterial Effectiveness of SDF and Fluoride Varnish Agents for Application in Pediatric Dentistry.

Objectives: To assess antibacterial effects of silver diamine fluoride (SDF) and fluoride varnish treatment against and .

Materials And Methods: The antibacterial effectiveness of SDF (group A) and fluoride varnish (group B) against was investigated in an microbiological investigation, with distilled water (group C) serving as the positive and negative controls. After 24 hours of incubation, the antibacterial efficiency was assessed using the agar well diffusion technique, and the diameter of the zones of inhibition (ZOI) was quantified.

Fabrication and Characterization of Steel-Base Metal Matrix Composites Reinforced by Yttria Nanoparticles through Friction Stir Processing.

Friction Stir Processing (FSP) was used to fabricate metal matrix composite, based on steel and reinforced with nano-sized yttrium oxide powder. The powder was packed in a narrow longitudinal groove of 2 mm depth and 1 mm width cut in the steel plate's rear surface. Different rotation speeds of 500-1500 rpm were used, at a fixed traveling speed of 50 mm·min.

Digital assessment of marginal accuracy in ceramic crowns fabricated with different marginal finish line configurations.

Aim: To digitally evaluate the marginal adaptation of different types of all-ceramic crowns on two different marginal configurations such as Shoulder and Chamfer of the prepared teeth.

Methods: The marginal fit of the crown specimens on the model of the prepared teeth were assessed using the dual scan replica technique. Two plastic teeth were prepared; one having a Shoulder finishing line (A), while the other with a Chamfer finish line (B).

An easy-to-use deep-learning model for highly accurate diagnosis of Parkinson's disease using SPECT images.

Accurate diagnosis of Parkinson's Disease (PD) at its early stages remains a challenge for modern clinicians. In this study, we utilize a convolutional neural network (CNN) approach to address this problem. In particular, we develop a CNN-based network model highly capable of discriminating PD patients based on Single Photon Emission Computed Tomography (SPECT) images from healthy controls.

Is bronchoscopic view a reliable method in diagnosis of tracheobronchial aspergillosis in critically ill non-neutropenic patients?

Introduction: Pulmonary aspergillosis is the main respiratory fungal infection however; its diagnosis is missed or delayed in critically ill non-neutropenic patients. Despite the utility of fiberoptic bronchoscopy for the evaluation of tracheobronchial aspergillosis (TBA) in immunocompromised patients has been extensively studied, however its utility in critically ill non-neutropenic patients is underestimated.

Objectives: To assess the bronchoscopic changes suspected TBA relative to the microbiological and histopathological aspects in critically ill non-neutropenic patients admitted to respiratory intensive care unit (RICU).

Types of yeasts that cause vulvovaginal candidiasis in chronic users of corticosteroids.

The current study aims to compare between the types of yeasts that cause vulvovaginal candidiasis (VVC) in women using corticosteroid medication compared to nonusers and estimate their sensitivity to available commercial antifungal agents. In a descriptive analytical cross-sectional study, we recruited 41 chronic corticosteroid users diagnosed clinically to have VVC from Women's Health Hospital, Assiut University, Egypt. Forty-seven age-matched women with VVC were recruited as a control group.

Impact of Non-Enzymatic Glycation in Neurodegenerative Diseases: Role of Natural Products in Prevention.

Non-enzymatic protein glycosylation is the addition of free carbonyls to the free amino groups of proteins, amino acids, lipoproteins and nucleic acids resulting in the formation of early glycation products. The early glycation products are also known as Maillard reaction which undergoes dehydration, cyclization and rearrangement to form advanced glycation end-products (AGEs). By and large the researchers in the past have also established that glycation and the AGEs are responsible for most type of metabolic disorders, including diabetes mellitus, cancer, neurological disorders and aging.

The effect of pomegranate mouthrinse on Streptococcus mutans count and salivary pH: An in vivo study.

Herbal mouthwashes have been considered to be a more advantageous option to their chemical counterparts, for a long-time. The use of pomegranate fruit dates from ancient times and reports of its therapeutic abilities have echoed throughout the ages. To evaluate the effect on the salivary pH and the Streptococcus mutans count in healthy subjects before and after pomegranate mouthrinse.

Effect of Brahmyadi Churna (Brahmi, Shankhapushpi, Jatamansi, Jyotishmati, Vacha, Ashwagandha) and tablet Shilajatu in essential hypertension: An observational study.

Hypertension (HTN) is one among the fiery health problems of the present era. Since it does not cause symptoms usually for many years until a vital organ is damaged. The present study was carried out on 40 patients of essential HTN with Brahmyadi Churna and tablet Shilajatu for a period of 1 month with milk as Anupana.

Reassessment of osteoporosis-related femoral fractures and economic burden in Saudi Arabia.

Unlabelled: The current study reassesses the prevalence of fragility fractures and lifetime costs in the Eastern Province of Saudi Arabia. Forty-two percent (391) of the fractures were at the neck of the femur, and 38.6 % (354) were inter-trochanteric fractures.

Does vaginal douching affect the type of candidal vulvovaginal infection?

The normal vaginal microbiota is a dynamic system that continually fluctuates under the environmental changes and different physiological conditions. Yeast infections of the vagina are caused by one of the species of fungus called Candida (C.).

The value of the pretreatment albumin/globulin ratio in predicting the long-term survival in colorectal cancer.

Background: Low serum albumin was found as a predictor of long-term mortality in colorectal cancer (CRC) patients. Our aim was to evaluate the value of the pretreatment albumin/globulin ratio (AGR) to predict the long-term mortality in CRC patients.

Methods: Patients were included if they had comprehensive metabolic panel (CMP) before treatment (surgery or chemotherapy).

Fortification with vitamin D: Comparative study in the Saudi Arabian and US markets.

Background And Objective: Vitamin D deficiency is common among Saudi Arabian population. To evaluate the current status of vitamin D fortification and calcium content of commonly consumed food items by the Saudi population and to compare it to US data.
