Objectives: To determine the diagnostic efficiencies of multiple diffusion-weighted imaging (DWI) techniques for hepatic fibrosis (HF) staging under the premise of high inter-examiner reliability.

Methods: Participants with biopsy-confirmed HF were recruited and divided into the early HF (EHF) and advanced HF (AHF) groups; healthy volunteers (HVs) served as controls. Two examiners analyzed intravoxel incoherent motion (IVIM) using the IVIM-DWI and diffusion kurtosis imaging (DKI) models. Intravoxel incoherent motion-DWI, DKI, and diffusion tensor imaging parameters with intraclass correlation coefficients (ICCs) of ≥0.6 were used to create regression models: HVs vs. EHF and EHF vs. AHF.

Results: We enrolled 48 HVs, 59 EHF patients, and 38 AHF patients. Mean, radial, and axial kurtosis; fractional anisotropy; mean, radial, and axial diffusivity; and α exhibited excellent reliability (ICCs: 0.80-0.98). Fractional anisotropy of kurtosis, f, and apparent diffusion coefficient showed good reliability (ICCs: 0.69-0.92). The real (0.58-0.67), pseudo- (0.27-0.76), and distributed diffusion coefficients (0.58-0.67) showed low reliability. In the HVs versus (vs.) EHF model, α (p=0.008) and ADC (p=0.011) presented statistical differences (area under curve [AUC]: 0.710). In the EHF vs. AHF model, α (p=0.04) and distributed diffusion coefficient (p=0.02) presented significant differences (AUC: 0.758).

Conclusion: Under the premise of high inter-examiner reliability, DWI and IVIM-derived stretched-exponential model parameters may help stage HF.

Objectives: To assess the level of satisfaction expressed for services rendered in the public health sector to clients who were seen at outpatient departments (OPDs) and primary healthcare (PHC) facilities in Al-Qassim Health Cluster in Saudi Arabia.

Methods: This study used a comparative cross-sectional study design, and data were obtained as secondary data from The Patient's Experience Platform. Data analysis was carried out using Stata (version 16), and the significance level was 5%.

Results: In comparing the mean satisfaction in 9 domains, statistically significantly higher means for the PHC facilities than the OPDs were seen across 7 domains: patients navigating health facilities (p=0.008), nursing services (p<0.001), physicians' services (p=0.004), radiological services (p<0.001), personal issues (p=0.003), the pharmacy (p=0.005), and general experience (p=0.036).

Conclusion: This study's findings are significant. They indicate that client satisfaction with services at PHC facilities was significantly higher than with services at hospital OPDs in Al-Qassim region. This underscores the need to improve the quality of services provided at OPDs to bring them to the same level as those provided by PHC facilities. Policymakers and implementers should, therefore, sustain efforts to make OPDs and PHC facilities more desirable for clients.

Objectives: To investigate the referral practices across different medical specialties and identify possible barriers to hand surgery referral. Rheumatoid hand deformities (RHDs) and thumb carpometacarpal (CMC) arthritis may require surgery once deformities occur. However, in Saudi Arabia, the rate of referrals to hand surgeons remains low.

Methods: This was a cross-sectional study that included 102 consultants of family medicine, rheumatology, and orthopedics across various regions of Saudi Arabia. A total of 30 institutions were contacted and requested to distribute a survey questionnaire to their physicians; these institutions included 8 private hospitals, 16 government hospitals, and 6 primary healthcare centers. The survey included questions on the incidence, rate, management, knowledge, and referral of patients with RHD and CMC arthritis using a 5-point Likert scale. The Kruskal-Wallis H test was utilized in our analysis to evaluate the differences in responses among the 3 specialties.

Results: For RHD and thumb CMC arthritis, the referral rate was higher among orthopedic surgeons compared to rheumatologists and family medicine physicians. The main barriers to referral were patient refusal, medical treatment alone being deemed adequate, and a lack of awareness of surgical options for management.

Conclusion: Our findings highlight discrepancies in patterns of physician referral of RHD and thumb CMC arthritis cases to hand surgeons, indicating the need for targeted interventions to improve referral rates and enhance patient outcomes.

Objectives: Surgeons may encounter a grossly normal appearing appendix in a patient with clinically suspected appendicitis. The purpose of this study is to determine the practice of pediatric surgeons in Saudi Arabia when this is encountered, and determine the reasons behind their decision making.

Methods: An electronic survey was sent to all pediatric surgeons in Saudi Arabia. Data points collected included demographics, peri-operative imaging preference, and personal practice when managing an intra-operative grossly normal appendix in symptomatic children.

Results: A total of 105 responses were obtained yielding a response rate of 33.8% The majority of respondents, 88 (87.1%) would remove the appendix while 13 (12.9%) would leave it in situ. The most common reason for removing the appendix was the possibility of microscopic/Endo appendicitis 71 (34.8%) while the most common reason for leaving the appendix in situ was the possible usage of the appendix for reconstructive benefits in the future 11 (50%). The overwhelming majority 87 (86.1%) felt that there were no sufficient guidelines on removal of the normal appearing appendix at the time of surgery for suspected acute appendicitis.

Conclusion: The majority of pediatric surgeons in Saudi Arabia would proceed with an appendectomy when an intra-operative grossly normal appendix is seen in patients suspected to have acute appendicitis. There is a clear lack of published pediatric guidelines and large studies to guide the correct course of action.

Objectives: To uncover the predictive value of systemic immune-inflammatory index (SII) and systemic inflammatory response index (SIRI) on early pregnancy loss.

Methods: A total of 535 individuals were enrolled in this retrospective analysis. The early pregnancy losses (EPL) group included patients between 18-35 years old who experienced EPL. The control group comprised healthy pregnant women who gave birth at ≥37 weeks.

Results: The EPL group had significantly lower plateletcrit (p=0.04), platelet distribution width (PDW, p<0.0001), and RDW (p<0.0001) and higher monocyte (p<0.0001) and SIRI (p<0.0001) values than the control group. The hemoglobin, white blood cells, platelet count, neutrophil count, lymphocyte count, mean platelet volume, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and SII values were not significantly different between the EPL and control groups (p>0.05). The cut-off value for the SIRI that offers the best sensitivity/specificity balance was 1.48 (sensitivity of 63%; specificity of 63%) in the receiver operating characteristics curve. Among the inflammatory parameters for predicting EPL, PDW had highest specificity (84%), and RDW had the highest sensitivity (80%).

Conclusion: This study provides compelling evidence that various inflammatory pathways may significantly contribute to EPL pathogenesis. Moreover, our findings suggest that SIRI could be a more effective marker than NLR, PLR, MLR, and SII in predicting EPL in an ongoing pregnancy, thereby potentially revolutionizing early pregnancy loss diagnostics.

Objectives: To review current evidence on using the geriatric nutritional risk index (GNRI) in predicting postoperative delirium (POD) in elderly patients.

Methods: The literature search was performed in core databases to include all the cohort studies on the association between GNRI and risk of POD for further meta-analysis.

Results: A total of 6 studies with 4242 patients underwent this meta-analysis, which showed that the risk of POD was higher in patients with moderate and high GNRI than the ones with low GNRI (odds ratio [OR]=2.04, 95% confidence interval [CI] [1.58, 2.64], p<0.001), and moderate and high GNRI significantly increased the risk of POD in patients of 60 to 75 years or above [OR=1.98, 95%CI (1.49, 2.62), p<0.001; OR=2.79, 95%CI (1.38, 5.64), p=0.004, respectively].

Conclusion: Therefore, moderate and high GNRI increased the risk of POD in elderly patients.

Objectives: To investigate whether magnetic resonance imaging (MRI) best detects early malignancy in high-risk women.

Methods: A retrospective, cross-sectional study, carried out at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, included 419 female breast cancer patients aged 16-84 years (mean age of 49). Data were collected from the radiological department's database to compare the MRI, ultrasound (US), and mammography results, with or without tissue biopsy.

Results: In diagnosing benign versus malignant lesions, MRI showed significant agreement with tissue biopsy, with high sensitivity (70%) and specificity (87%); its positive predictive value (PPV) was 92% and negative predictive value (NPV) was 56%. While US has a PPV of 84% and NPV of 63%; with a sensitivity (79%) and specificity (71%). In patients without tissue biopsy, there was little difference between mammography and US compared with MRI results.

Conclusion: Magnetic resonance imaging is more effective than US and mammography for early detection of BC. It showed high sensitivity in detecting breast lesions and high specificity in characterizing their nature when correlated with pathological results. Ultrasound screening followed by MRI is suggested for undetected or suspected lesions. This will increase the breast lesion detection rate, reduce unneeded tissue biopsies, and enhance the disease's survival rate.

Objectives: To determine the prevalence of electronic cigarette (e-cigarette) usage among young adults in Riyadh, Saudi Arabia; their perceptions of its harm and legal age, and the reasons and factors influencing their use.

Methods: This cross-sectional study was carried out within the general community of Riyadh, Saudi Arabia, between December 2023 and April 2024. Participants aged 18-25 years were included. A self-administered online questionnaire was used to gather demographic data, perceptions, and attitudes toward e-cigarettes and reasons for their use.

Results: The majority of the 476 participants were female (n=378, 79.4%) and Saudi nationals (n=451, 94.7%). Current e-cigarette usage was 10.5% (n=50), being more prevalent among males (n=46, 46.9%) and non-Saudis (n=12, 48%). Respondents living alone (n=11, 34.4%) or with friends (n=4, 80%), those who perceived e-cigarettes as safer than cigarettes (n=38, 42.2%), or were unsure of age restrictions demonstrated high usage. Key motivators included flavors available, stress relief, and curiosity.

Conclusion: Eelectronic cigarette use among Riyadh's youth was remarkable, especially among males. Reducing the e-cigarette usage prevalence in Saudi Arabia should be prioritized.
