Patient-derived tumor organoids: A preclinical platform for personalized cancer therapy.

Patient-derived tumor organoids (PDTOs) represent a significant advancement in cancer research and personalized medicine. These organoids, derived from various cancer types, have shown the ability to retain the genetic and molecular characteristics of the original tumors, allowing for the detailed study of tumor biology and drug responses on an individual basis. The success rates of establishing PDTOs vary widely and are influenced by factors such as cancer type, tissue quality, and media composition.

Health-Related Quality of Life and Psychological Distress Status in Survivors of Nasopharyngeal Carcinoma: A Retrospective Study.

Introduction Nasopharyngeal carcinoma (NPC) is an uncommon cancer globally, with a low incidence in Western countries. However, this rate increases significantly in some endemic regions, including the Middle East. Although studies have evaluated the physical health outcomes, treatment efficacy, and short-term effects, long-term effects - especially quality of life (QoL) - have been neglected.

The impact of body position on vital capacity among pregnant women in the second trimester.

Background: Pregnancy introduces significant physiological changes, notably impacting respiratory dynamics, especially during the second trimester. Data remain inconclusive about how body posture might influence lung function in pregnant women. We aimed to examine the impact of body position on slow vital capacity in pregnant women during their second trimester.

Herpesvirus Entry Mediator as an Immune Checkpoint Target and a Potential Prognostic Biomarker in Myeloid and Lymphoid Leukemia.

Herpesvirus entry mediator (HVEM) is a molecular switch that can modulate immune responses against cancer. The significance of HVEM as an immune checkpoint target and a potential prognostic biomarker in malignancies is still controversial. This study aims to determine whether HVEM is an immune checkpoint target with inhibitory effects on anti-tumor CD4 T cell responses in vitro and whether gene expression is dysregulated in patients with acute lymphocytic leukemia (ALL).

Social Comparison and Body Image in Teenage Users of the TikTok App.

Background And Aim: The TikTok app is one of the video-based social media platforms that is currently trending and commonly used by teenagers. The data about teenage users of the TikTok app are limited. This study aimed to estimate the prevalence of TikTok app use among teenagers in Saudi Arabia and to investigate the association between TikTok app use and the social comparison and the body image of the study population.

The Prevalence of Irritable Bowel Syndrome and Its Co-existence With Migraine in Medical and Non-medical Students at Al-Baha University, Saudi Arabia.

Background: It was hypothesized that the prevalence of irritable bowel syndrome (IBS) and migraine and their co-existence are higher among medical students. In this study, we aim to establish the prevalence of IBS and migraine in the medical and non-medical students at Al-Baha University, Saudi Arabia, and to observe the association and relationship between IBS and migraine using the Rome IV diagnostic criteria for IBS and the International Classification of Headache Disorders (ICHD)-3 criteria for migraine.

Methodology: This cross-sectional study was done on the Saudi Arabian campus of Al-Baha University between July 2022 and July 2023.

Knowledge and Awareness About Gastric Cancer Among the General Population in Al-Baha City, Saudi Arabia.

Background Gastric cancer is a significant health concern worldwide, and its incidence varies across different populations. This study aimed to assess the level of knowledge and awareness of gastric cancer among the general population in Al-Baha City, Saudi Arabia.  Methodology This is a cross-sectional study that was conducted among the residents of Al-Baha city older than 18 years.

Worst pattern of invasion and other histopathological features in oral cancer as determinants of prognosis and survival rate: A retrospective cohort analysis.

Oral cavity squamous cell carcinoma (OCSCC) is a well-recognized malignancy of the head and neck. Studies on patients with early-stage oral cancer have shown that they develop locally recurring and/or regional lymph node metastasis, which results in disease-associated mortality. Thus, early-stage oral cancer does not always present good prognoses.

Determinants of quality of life in patients with hemorrhagic stroke, Saudi Arabia: A cross-sectional study.

Background: Previous studies demonstrated that stroke had an inverse impact on patients' physical, mental, and social quality of life.

Aim: To determine factors contributing to the health-related quality of life (HRQOL) of Saudi hemorrhagic stroke survivors.

Methods: A cross-sectional study was done at King Abdulaziz University Hospital (KAUH), Jeddah, KSA, on adult stroke patients.

A Novel Ensemble-Based Technique for the Preemptive Diagnosis of Rheumatoid Arthritis Disease in the Eastern Province of Saudi Arabia Using Clinical Data.

Rheumatoid arthritis (RA) is a chronic inflammatory disease caused by numerous genetic and environmental factors leading to musculoskeletal system pain. RA may damage other tissues and organs, causing complications that severely reduce patients' quality of life. According to the World Health Organization (WHO), over 1.

Preemptive Diagnosis of Alzheimer's Disease in the Eastern Province of Saudi Arabia Using Computational Intelligence Techniques.

Alzheimer's Disease (AD) is a silent disease that causes the brain cells to die progressively, influencing consciousness, behavior, planning ability, and language to name a few. AD increases exponentially with aging, where it doubles every 5-6 years, causing profound implications, such as swallowing difficulties and losing the ability to speak before death. According to the Ministry of Health in Saudi Arabia, AD patients will triple by 2060 to reach 14 million patients worldwide.

A novel stacking ensemble for detecting three types of diabetes mellitus using a Saudi Arabian dataset: Pre-diabetes, T1DM, and T2DM.

Glucose is the primary source of energy for cells, which are the building blocks of life. It is given to the body by insulin that carries out the metabolic tasks that keep people alive. Glucose level imbalance is a sign of diabetes mellitus (DM), a common type of chronic disease.

Sex differences in pregabalin-seeking like behavior in a conditioned place preference paradigm.

Substance abuse is a chronic, relapsing disorder characterized by compulsive drug use regardless of negative consequences. Incremental increases in pregabalin abuse have been observed in Saudi Arabia and throughout the world. In previous studies, the potential for pregabalin abuse with escalating doses of the drug (30, 60, 90, and 120 mg/kg) were investigated in male mice.

Practices and Attitudes of Dental Loupes and Their Relationship to Musculoskeletal Disorders among Dental Practitioners.

Objective: A dental loupe is a tool used by many dentists and dental students to improve visual field and performance. This study aims to assess the practices and attitudes about dental magnification loupes and their relationship to musculoskeletal disorders.

Materials And Methods: A cross-sectional study was conducted involving 400 dental students and dentists in four dental colleges in Jeddah, Saudi Arabia.

Stability issues and approaches to stabilised nanoparticles based drug delivery system.

Nanoparticles form the fundamental building blocks for many exciting applications in various scientific disciplines due to its unique features such as large surface to mass ratio, targeting potential, ability to adsorbed and carry other compound which makes them suitable for biomedical applications. However, the problem of the large-scale synthesis of nanoparticles remains challenging due to physical instability associated with nanoparticles which lead to generation of aggregates particles with high polydispersity index (PDI) indicating low particle homogeneity and eventually loss of their special nanoscale properties. The stabilisation concept can be generated by repulsive electrostatic force, which nanoparticles experience, when they are surrounded by a double layer of electric charges.

Chromophobe renal cell carcinoma of the kidney with neuroendocrine differentiation: A case report with review of literature.

Chromophobe renal cell carcinoma (chRCC) is a distinctive type of malignant kidney tumor characterized by large cells with defined cell membrane. Primary renal neuroendocrine tumors (NET) are rare with morphology similar to NET at other sites. There are few case reports describing the coexistence of these 2 neoplasms within the same tumor mass.
