Background: Kidney stones can significantly impact individuals, but existing literature often overlooks the comprehensive effects by not considering the various factors such as stone size, presence of obstruction, and treatment methods, among those with and without diabetes. This study seeks to explore the relationship between diabetes and kidney stone formation, addressing these gaps in research.

Methodology: This cross-sectional study assesses the diverse impacts of kidney stones on adults diagnosed with type 2 diabetes mellitus and nondiabetic adults from 2019 to 2022 in Jeddah, Saudi Arabia.

Background: Recent evidence suggests that clonally expanded cytotoxic T cells play a role in various autoimmune diseases. Late-onset rheumatoid arthritis (LORA) exhibits unique characteristics compared to other RA forms, suggesting distinct immunological mechanisms. This study aimed to examine the involvement of cytotoxic T cells in LORA.

The window technique is a highly useful clinical procedure for resolving several issues while taking a final impression of a patient with a mobile or displaceable anterior maxillary ridge, also referred to as a flabby ridge. This kind of ridge is particularly problematic due to the underlying tissues lacking strength and resilience, making it challenging to achieve a solid and comfortable denture fit. This typically exacerbates the problem, as conventional pressure during impression-making induces further displacement, which reduces the impression's precision.

IgG4-related disease (IgG4-RD) is an immune-mediated disorder characterized by organ enlargement and dysfunction. The formation of tertiary lymphoid tissues (TLTs) in affected organs is crucial for understanding IgG4-RD, as T follicular helper (Tfh) 2 cells within TLTs drive IgG4+B cell differentiation, contributing to mass formation. Key cytokines IL-4 and IL-10, produced by Tfh2 cells, are essential for this process.

Article Synopsis
  • The study aimed to investigate the differences in cytotoxic CX3CR1+ T cell subsets between two types of large vessel vasculitis: giant cell arteritis (GCA) and Takayasu's arteritis (TAK).
  • Scientists analyzed blood samples from 30 patients (22 with GCA and 8 with TAK) and 16 healthy individuals to compare the proportion of CX3CR1+ CD4+ and CD8+ T cells, as well as their presence in inflamed arteries.
  • The results reveal a significant increase in CX3CR1+ CD4+ T cells in GCA, associated with inflammation severity, while no such correlation was found in TAK, suggesting that these cells play a crucial role

Article Synopsis
  • A meta-analysis was conducted to assess the effectiveness and safety of DEXTENZA, a dexamethasone insert, for treating allergic conjunctivitis.
  • The study analyzed data from four randomized controlled trials with 323 participants, finding significant reductions in conjunctival itching and redness when using DEXTENZA compared to a placebo.
  • Overall, DEXTENZA showed promise as a reliable treatment option with no significant differences in adverse effects compared to placebo.

IgG4-related disease (IgG4-RD) is an immune disorder characterized by organ enlargement and fibrosis leading to functional impairment. Key immune cell subsets contributing to the pathogenesis of IgG4-RD include T follicular helper 2 cells (Tfh2), Tfh1, CX3CR1 + cytotoxic T cells (CX3CR1 + CTLs), Tregs and IgG4 + B cells. Tfh2 and Tregs are commonly involved in inducing IgG4 class-switching in this disease.

Human T follicular helper (Tfh) cells play a crucial role in orchestrating B cell differentiation, maturation, and immunoglobulin class switching. Recent studies have underscored the presence of Bcl-6 + Tfh cells not only in secondary lymphoid organs but also within tertiary lymphoid structures at inflammatory sites, emphasizing their pivotal role in disease pathogenesis. Furthermore, Tfh cells have been found to transit between lesion sites, lymph nodes, and peripheral blood, as revealed by T cell receptor repertoire analysis.

Circumscribed choroidal hemangioma (CCH) is a sort of non-malignant hamartomatous tumor that occurs in the choroidal layer of the eye. It is a rare condition that affects people between their second and fourth decades of life, leading to significant deterioration of vision. One of the most catastrophic consequences of CCH is exudative retinal detachment (ERD), which has a severe impact on vision.

Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammatory synovitis, eventually leading to joint destruction. Remarkable advancements in the emergence of molecular targeted therapies and the treatment strategy based on treat-to-target have made it possible for patients to lead their daily lives without disabilities. Specifically, early diagnosis and appropriate treatment without missing a 'window of opportunity' are crucial for improving joint outcomes.

Physical inactivity and sedentary behavior pose significant health concerns, particularly among young adults like college students. However, little research exists on the attitudes towards physical activity among Saudi Arabian healthcare students. This study aimed to assess the prevalence of physical activity and determine the reason for being physically inactive among students and interns across all programs in the College of Applied Medical Sciences (CAMS) at King Saud University (KSU), Riyadh, Saudi Arabia.

Background Diabetes mellitus imposes a significant psychological and social burden on the affected individuals. The impact of type 1 diabetes mellitus (T1DM) on psychosocial development has not been well investigated in the literature. We aim to fill the aforementioned gap by conducting a comparative study to accurately assess the impact of this chronic disease on psychosocial development among adolescents in Saudi Arabia.

Providing palliative care to patients with life-threatening illnesses requires multidisciplinary efforts from different healthcare providers. Identifying the attitude, knowledge, and intentions of pharmacists to provide this service in Saudi Arabia is essential. Therefore, this study aimed to identify the palliative care knowledge, intentions, attitudes, subjective norms, and perceived behavioural control of pharmacists and what factors predict their intentions.

Recent technological progress has greatly advanced our understanding of human immunology. In particular, the discovery of human T follicular helper (Tfh) and T peripheral helper (Tph) cells has significantly advanced our understanding of human adaptive immune system. Tfh and Tph cells share similar molecular characteristics and both play critical roles in B cell differentiation and maturation.

Although several interventions are utilized for pain management, opioids remain the most effective intervention for moderate to severe pain. Despite opioids being the most potent analgesics used in different pain settings, several factors impede the optimal prescribing of opioids. The study seeks to identify and address the barriers physicians face to prescribing opioids in managing pain.

Background In palliative care, therapeutic benefit and desired health outcome might be affected by non-adherence to medications, especially among patients with advanced illnesses, such as cancer. The consequences of non-adherence to medications could include poor health outcomes, recurrent admissions, medication waste, as well as increased morbidity and mortality. The aim of this study was to measure the level of medication adherence in palliative care patients visiting the outpatient clinic at King Fahad Medical City.
