Background: Central venous catheterization (CVC) is a critical clinical procedure. To avoid complications, possessing good knowledge regarding the CVC care bundle and skills for the proper insertion and maintenance of CVC are important.

Objectives: To evaluate the effectiveness of an educational intervention and the use of an interactive response system in enhancing the CVC bundle care and insertion skills of medical students undergoing critical care medicine training.

Materials and methods: Sixth-year medical students (equivalent to fourth-year students in the United States) engaged in didactic lessons, interactive demonstrations, and simulator training facilitated by a CVC team comprising three thoracic and two vascular surgeons (all with a minimum 5 years of experience in central venous access) during their intensive care unit (ICU) rotation. Self-reported knowledge and confidence levels were assessed using pre-and posttests administered through the Zuvio App, an interactive response system.

Results: A total of 60 students underwent the educational intervention, of which 54 completed the pretest and 40 completed the posttest. In the posttest, significant improvement was found in the CVC bundle care competency and understanding (P = 0.002), preprocedural preparation (P = 0.002), insertion procedures (P = 0.004), complications (P = 0.003), and insertion depth decisions (P = 0.001). Staff and students reported that assessment and interaction via the Zuvio App were valuable, practical, and feasible in a clinical setting, providing trainees with an individual competency portfolio of receiving precise medical education.

Conclusions: Integrating the training provided by a specialized team with an interactive response system enhanced the knowledge and competency level in CVC insertion among medical students in this study.

Background: Mechanical ventilation provides essential support for critically ill patients in several diagnoses; however, extubation failure can affect patient outcomes. From Saudi Arabia, no study has assessed the factors associated with extubation failure in adults.

Methods: This prospective observational study was conducted in the intensive care unit of a tertiary care hospital in Riyadh, Saudi Arabia. Adult patients who had been mechanically ventilated via the endotracheal tube for a minimum of 24 hours and then extubated according to the weaning protocol were included. Failed extubation was defined as reintubation within 48 hours of extubation.

Results: A total of 505 patients were included, of which 72 patients had failed extubation (14.3%, 95% CI: 11.4%-17.7%). Compared with the failed extubation group, the successfully extubated group had significantly shorter duration of mechanical ventilation (mean difference: -2.6 days, 95% CI: -4.3 to -1; P = 0.001), a slower respiratory rate at the time of extubation (mean difference: -2.3 breath/min, 95% CI: -3.8 to -1; P = 0.0005), higher pH (mean difference: 0.02, 95% CI: 0.001-0.04; P = 0.03), and more patients with strong cough (percent difference: 17.7%, 95% CI: 4.8%-30.5%; P = 0.02). Independent risk factors of failed extubation were age (aOR = 1.02; 95% CI: 1.002-1.03; P = 0.03), respiratory rate (aOR = 1.06, 95% CI: 1.01-1.1; P = 0.008), duration of mechanical ventilation (aOR = 1.08, 95% CI: 1.03 - 1.1; P < 0.001), and pH (aOR = 0.02, 95% CI: 0.0006-0.5; P = 0.02).

Conclusion: Older age, longer duration of mechanical ventilation, faster respiratory rate, and lower pH were found to be independent risk factors that significantly increased the odds of extubation failure among adults.

Background: The RHD gene is one of the most complex blood group genes. The molecular background of the RHD gene in RhD-negative and RhD-positive individuals varies within and among different populations. Knowing the molecular basis of the RHD gene in a specific population is required to establish effective genotyping methods. While the molecular basis has been revealed in many ethnicities, such as Caucasians and Black Africans, it still requires elucidation in Arabs.

Objectives: The aim of this study was to gain insights into the molecular basis of RhD-positive and RhD-negative phenotypes in Saudi donors.

Materials and methods: Conventional serological tests were used to determine the Rh phenotypes in 136 Saudi donors by typing D, C, c, E, and e antigens. Multiplex-PCR and Single Specific Primer-PCR were used to detect the presence of exons 3, 4, and 7 and the hybrid Rhesus box gene, respectively, in RhD-negative and/or RhD-positive samples.

Results: Of the 136 samples, 70 were RhD positive and 66 were RhD negative. None of the RhD-negative donors had any of the three tested exons, whereas the hybrid Rhesus box gene was detected in all, indicating the zygosity status of the RHD deletion allele. The hybrid Rhesus box gene was detected in 79% of the RhD-positive individuals, suggesting high frequencies of RHD-negative haplotypes.

Conclusions: The study findings indicate that Saudis with the RhD-negative phenotype are likely to have an entire RHD deletion in the homozygous state. However, a more comprehensive analysis of variant RHD alleles in the Saudi population is required to implement effective and dedicated molecular RHD typing strategies.

Background: Audiovisual distraction is a potentially good technique to reduce medical treatment procedure-related fear and anxiety among children. However, few studies have assessed its effectiveness.

Objective: To conduct a systematic review and meta-analysis for evaluating the effectiveness of audiovisual distraction in reducing pain anxiety in pediatrics.

Methods: Randomized control trials and experimental studies that reported the use of audiovisual distraction during medical/dental treatments among children aged 3-8 years, used the Face, Legs, Activity, Cry, Consolability (FLACC) scale to assess pain, and were published between 2005-2021 and in English were retrieved from PubMed, Scopus, and Web of Science. A random-effects model was used for evidence analysis.

Results: A total of four studies were included in the systematic review and meta-analysis: two were from South Asia and one each were from Africa and North America. Three of these studies were randomized control trials. The variability among the studies was high. Three of the four studies found that AV techniques were significantly effective in reducing pain during procedures compared with the control group (P < 0.00001), while one study found no difference; the cumulative evidence in the forest plot was similar.

Conclusion: Cumulative evidence suggests that the use of audiovisual distraction is an effective strategy in reducing medical/dental procedures-related pain anxiety among children aged 3-8 years. However, evidence on this is currently limited, and thus further studies are required using various AD techniques and on different populations to substantiate these findings.

Background: Several studies have reported a strong association between depression and hypothyroidism, including from several regions of Saudi Arabia. However, studies on the frequency of depression among patients with hypothyroidism from the Western region of Saudi Arabia is limited.

Objectives: To determine the frequency and risk factors of depression among patients with hypothyroidism in the Western Region of Saudi Arabia.

Materials and methods: This cross-sectional study was conducted at a tertiary care hospital in Jeddah, Saudi Arabia, and included adult patients diagnosed with hypothyroidism. After contacting the patients through phone calls and obtaining their consent, a questionnaire weblink was sent. The first part of the questionnaire elicited details regarding demographics and history of hypothyroidism, while the second part comprised the Arabic version of the Patient Health Questionnaire-9 to evaluate depression.

Results: A total of 100 patients completed the survey, of which 80% were found to have depression (mild: 35%, moderate: 26%, moderate to severe: 12, severe: 7%). There was no significant association between depression and gender, age group, employment status, and marital status. In the bivariate analysis, a significant association was found between depression and reporting fatigue (P < 0.001), constipation (P < 0.001), hair loss (P = 0.002), cold intolerance (P = 0.014), dry skin (P = 0.028), memory problems (P = 0.029), and menorrhagia (P = 0.037). However, in the multivariate analysis, only reporting fatigue was found to be significantly associated with depression (P = 0.040; OR = 15.215).

Conclusion: This study found that the prevalence of depression was very high among patients with hypothyroidism in the Western region of Saudi Arabia, and that fatigue is an independent risk factor of depression.

Objectives: This study aimed to assess the level of illness perception and medication adherence among adult patients with type 2 diabetes mellitus (T2DM) in Jeddah, Saudi Arabia, with a specific focus on understanding how these two factors may be related.

Materials and methods: This descriptive correlation study included all adult patients with T2DM attending the Jeddah Care Centre for Diabetes and Hypertension at King Abdulaziz Hospital between January and April 2022. Data were collected using a questionnaire that elicited sociodemographic and clinical information, and the Arabic versions of the Brief Illness Perception Questionnaire and the Morisky Medication Adherence Scale. Descriptive statistics and Pearson's correlation analysis were used for data analysis.

Results: A total of 365 patients were included (mean age: 50.9 ± 15.9 years), with the majority being female (53.4%). Overall, the level of medication adherence was moderate (mean score: 5.36 ± 1.73). Patients with lower medication adherence perceived the consequences of T2DM as more severe, had a stronger association with the illness identity, and experienced more intense emotional responses (for all, P < 0.001). Conversely, patients with higher adherence had a greater sense of personal control, a stronger belief in treatment effectiveness, and a better understanding of the illness (for all, P < 0.001).

Conclusion: The study found a correlation between illness perception and medication adherence in patients with T2DM. Addressing patients' perceptions may enhance their ability to manage the condition more effectively.

Sarcoidosis is a disease of unknown etiology, characterized by noncaseating granulomas. Generally, the condition primarily manifests in the lungs. Extrapulmonary involvement is common, but localization in the gastrointestinal system is rare. Here, we present the case of a 37-year-old male who became increasingly hemodynamically unstable during the diagnostic workup for sarcoidosis due to acute variceal bleeding. The underlying mechanism was later attributed to portal hypertension caused by hepatic involvement of the disease. This case demonstrates the importance of considering variceal hemorrhage as a rare but life-threatening complication of gastrointestinal localization of sarcoidosis.

Background: In Retzius-sparing robot-assisted radical prostatectomy (RARP), lymphocele formation is a troublesome complication. The use of peritoneal flaps has emerged as a promising novel technique to tackle this complication. We explored this technique by suturing both the medial peritoneal flaps to each other and keeping them distracted so that the lymphadenectomy beds are left wide open.

Objective: To assess the efficacy of our peritoneal distraction technique on lymphocele rates following Retzius-sparing RARP.

Materials and methods: This retrospective study included patients with localized prostate carcinoma who underwent Retzius-sparing RARP with standard pelvic lymph node dissection between May 2014 and September 2022 at Aster Medcity, Kochi, India. Based on the use of the technique, patients were divided into two groups: peritoneal distraction and closed groups. Both groups were matched using the propensity scoring method in a 1:1 ratio.

Results: A total of 272 patients were included, of which 89 (32.7%) belonged to the peritoneal distraction group. Although the overall incidence of lymphocele between the two groups were comparable, none of the patients in the peritoneal distraction group required any intervention for lymphocele management, as opposed to 7 patients from the closed group (3.9%; P = 0.015). No significant association was found between lymphocele formation and serum prostate-specific antigen level, Gleason score, and the number of lymph nodes harvested.

Conclusions: This study found that peritoneal distraction stitch is a simple and effective technique to reduce the incidence of symptomatic lymphocele that require intervention after Retzius-sparing RARP.

Hepatoblastoma is a rare liver cancer that occurs most often in children who present with lower birth weight. Cerebral palsy (CP) is a neurodevelopmental disorder distinguished by irregularities in muscle tone, movement, and motor skills. CP is caused by damage to the developing brain and is often associated with secondary complications such as severe constipation. Clinicians must be aware of sudden worsening constipation occurring in CP children because it can also be a sign of hepatoblastoma. The aim of this review is to summarize the current understanding of the risks for hepatoblastoma development in children with CP. Cancer risks likely include dysfunction of the immune system surveillance in CP children. Elevated C-reactive protein and tumor necrosis factor-alpha levels may be higher in children with CP, which weakens their innate immune system. Metabolic disruption increases the risk of some cancers, and poor nutrition and reduced growth that occur in CP patients may have an impact on cancer development through a loss in immune function. Increased mobility and physical activity can increase the T-cell, natural killer cell, and neutrophil population. Children with CP tend to engage poorly in physical activity, and consequently, their immune system is affected. There are multiple factors associated with CP that increase the risk of childhood cancers such as hepatoblastoma.

Background: Telehealth is in early stages in the Kingdom of Saudi Arabia (KSA). Identifying barriers to using telehealth is an essential step prior to its implementation; however, no theoretically based scales exist for the same purpose.

Objective: To design a theory-based scale capable of measuring telehealth users' perceptions of benefits, barriers, and social influence in the KSA.

Methods: The Saudi Telehealth Acceptance Scale (STAS) was constructed based on the Unified Theory of Acceptance and Use of Technology and its content validity was determined by eight experts using the modified Delphi process. Only items with a content validity index score of ≥0.83 were chosen. Finally, the face validity of the questionnaire for healthcare professionals, which was in English, was determined by eight healthcare professionals, and for the patient version, which was in Arabic, by six patients.

Results: Initially, 37 items were identified; however, after Round 1, 29 items remained and after Round 2, 24 items were included in the STAS for both healthcare professionals and patients. In the healthcare professionals scale, there were 7 performance expectancy (PE) items, 6 effort expectancy (EE) items, 3 social influence (SI) items, 4 facilitating conditions (FC) items, and 4 behavioral intention (BI) items, while in the scale for patients, there were 9 PE items, 4 EE items, 3 SI items, 4 FC items, and 4 BI items.

Conclusions: The two new scales showed evidence of content and face validity. The significance of the two scales is that they were both designed in the context of the healthcare system in the KSA and could provide standardized data collection tools to measure the acceptance of telehealth among HCPs and patients.
