Background Sickle cell disease (SCD) is a genetic blood disorder characterized by abnormal hemoglobin S, leading to red blood cell deformities, chronic hemolysis, and frequent vaso-occlusive crises (VOC). While advancements in medical care have improved survival rates, adults with SCD continue to face substantial challenges in their quality of life (QoL) due to chronic pain, recurrent VOCs, and various complications. This study aimed to evaluate the health-related quality of life (HRQoL) in adult patients aged 14 years and above with SCD and identify key factors influencing patient outcomes using the Adult Sickle Cell Quality of Life Measurement Information System (ASCQ-Me).

Aim: To explore the physicians' knowledge, awareness, and perspectives on HRQoL and mental health aspects of people with T2DM in Jeddah, Saudi Arabia.

Methods: A cross-sectional survey study was conducted over a three-month period (October to December 2022) on 54 physicians. Physicians were requested to respond to a 12-item researcher-designed, self-administered survey questionnaire that explored their perspectives regarding the importance of their patients' general, physical, and mental health aspects using the 12-item Short Form Health Survey Version 2 (SF-12v2).

  • Rheumatic fever (RF), an autoimmune condition following untreated strep throat, mainly impacts children and can lead to serious heart issues, highlighting the need for awareness and prevention, especially in low-resource areas.
  • A study in Al-Baha, Saudi Arabia, surveyed 415 parents using an online questionnaire to evaluate their knowledge, attitudes, and practices regarding RF and RHD, revealing that most participants had poor knowledge and negative attitudes toward RF.
  • Results showed that only around 4.8% had good knowledge of RF, while 69.2% demonstrated good practices; females were more likely to have better practices than males, suggesting a need for enhanced educational initiatives by health authorities to improve understanding and prevention of these

The increasing prevalence of antibiotic resistance, driven by the production of extended-spectrum beta-lactamases (ESBLs), presents a critical challenge to current medical treatments, particularly in clinical settings. Understanding the distribution and frequency of ESBL-producing bacteria is essential for developing effective control strategies. This study investigated the antibiotic resistance and extended-spectrum beta-lactamase (ESBL) production in bacterial isolates in clinical and non-clinical (food) specimens in Tabuk, KSA.

Background: The Directly Observed Treatment-Short Course (DOTS) Programme was implemented by WHO and includes a combination of four anti-tuberculosis (TB) drugs (isoniazid, pyrazinamide, ethambutol and rifampicin) for a period of six months to eradicate the TB infection completely. Diabetes mellitus (DM) is recognized as one of a strong contributor of TB according to World Health Organization (WHO). The presence of diabetes mellitus type 2 (DM type 2) makes TB treatment complicated.

Endodontic therapy aims to treat or prevent apical periodontitis, a condition characterized by inflammation of the periapical tissues at the apex of the tooth root. This case study demonstrates the successful nonsurgical and surgical management of a large periapical lesion involving the lower central incisors with root displacement induced by a periapical granuloma. A patient was referred from the maxillofacial department for endodontic treatment due to persistent pain and swelling in the lower anterior region started two months ago.

The rabbit carcasses used in this study were buried at depths of 20 and 40 cm, were examined to construct a fly succession database on buried carrion in Riyadh, Saudi Arabia. Twenty-four rabbits were buried, 12 at 20 cm and 12 at 40 cm. One carcass at each depth was exhumed at 10-day intervals up to 120 days.

Background A central line-associated bloodstream infection (CLABSI) is defined as a primary bloodstream infection (BSI) in a patient that had a central line within the 48-hour period before the development of the BSI and is not bloodstream-related to an infection at another site. CLABSI is a common healthcare-associated infection and a significant cause of morbidity and mortality. Methods This systematic review included studies published within the past 13 years that examined risk factors and clinical impact variables associated with CLABSI, using the Centers for Disease Control (CDC)/National Healthcare Safety Network (NHSN) criteria for defining catheter-associated infection, and included participants of all ages.

Burial has a special influence on carrion fauna, which may change the rate of decomposition and so affect postmortem estimates. This study aimed to identify species and succession of beetles on buried remains. From 28 January to 31 May 2021, we examined the Coleoptera on buried and exposed rabbit carcasses, on the campus of the University of King Saud in an area measured around 175 m by 250 m.

Background: Over the past few decades the benefits of assessing Quality of Life (QoL) and mental health in patients with Type 2 Diabetes Mellitus (T2DM) have steadily increased with limited studies relating to the most useful method to assess these patients. This study aims to identify, review, summarise, and evaluate the methodological quality for the most validated commonly used health-related QoL and mental health assessment measurements in diabetic patients.

Methods: All original articles published on PubMed, MedLine, OVID, The Cochrane Register, Web of Science Conference Proceedings and Scopus databases were systematically reviewed between 2011 and 2022.

The gastrointestinal tract's most commonly occurring primary mesenchymal tumor is the gastrointestinal stromal tumor (GIST). However, few cases worldwide were reported associated with renal cell carcinoma (RCC). Therefore, we aimed to identify the association of genitourinary tumors in patients with GIST in our tertiary care hospital in Saudi Arabia and compare it to the literature.

The failure of chemotherapy in the treatment of carcinoma is mainly due to the development of multidrug resistance (MDR), which is largely caused by the overexpression of P-glycoprotein (P-gp/ABCB1/MDR1). Until recently, the 3D structure of the P-gp transporter has not been experimentally resolved, which restricted the discovery of prospective P-gp inhibitors utilizing techniques. In this study, the binding energies of 512 drug candidates in clinical or investigational stages were assessed as potential P-gp inhibitors employing methods.

Article Synopsis
  • The study examines the prevalence and antibiotic resistance of carbapenem-resistant uropathogens from the Enterobacteriaceae family in diabetic patients, focusing on samples collected over a year.
  • The most common pathogens identified were Escherichia coli and Klebsiella pneumoniae, with over 50% of isolates showing resistance to 22 antibiotics, especially tetracycline, ampicillin, and cefazolin.
  • While resistance to carbapenems was high, it was less common than ESBL producers; interestingly, the isolates had shown some susceptibility to newer antibiotics like cefiderocol and eravacycline.
