Characteristics of ocular-related emergency department visits: Five-years data from a tertiary care center in Riyadh, Saudi Arabia.

Ocular emergencies (OE) include ocular trauma, infections, retinal detachment, and uveitis. Due to the limited number of studies describing ocular emergencies requiring Emergency Department (ED) visits in Saudi Arabia, there is a need for further studies addressing this topic. Therefore, this study aimed to assess and describe the incidence, clinical presentation, and causes of ocular-related ED visits at a tertiary hospital in Riyadh, Saudi Arabia. This was a retrospective cohort study. Medical records were reviewed for all patients (all age groups) patients presenting at the ED from 1 January 2019 to 31 October 2023 where data for patients with any ocular emergency was extracted using an Excel sheet. Data analysis was performed using RStudio (R version 4.3.1). Baseline information was described using frequencies and proportions. Types of Ocular emergencies were described using the International Classification of Diseases, 10th Revision (ICD-10) codes and presented using frequencies and proportions. The distribution of ocular emergencies across months and age groups was expressed using chart figures. A total of 15,321 ocular-related ED visits were included in this study. Almost 51% of patients were males. The mean age at diagnosis was 25.5 ± 22.1 years. More than half of the patients (51.0%) were diagnosed during childhood (<18 years), while proportions of older ages declined gradually. Average presentations of ocular emergencies in a single month ranged from 200 to 400. Conjunctival disorders including conjunctivitis (29.8%) were the most frequent ocular emergencies. The findings of this study showed that ocular emergencies are more prevalent in younger patients (aged <18 years), more commonly due to conjunctivitis. This highlights the need for policymakers to assess the causes of such emergency in this population and implement prevention strategies. Moreover, an average of 200 to 400 emergency visits per month are ocular-related. This finding could help policymakers understand the burden of ocular emergencies on the ED and the pressure that could add to the ED staff to provide appropriate care for these patients.

Nutritional status of Saudi obese patients undergoing laparoscopic sleeve gastrectomy, one-year follow-up study.

Bariatric surgery has significantly increased globally as an effective treatment for severe obesity. Nutritional deficits are common among candidates for bariatric surgery, and follow-up of nutritional status is critically needed for post-surgery healthcare management. This observational prospective study was conducted at King Khalid University Hospital in Riyadh. Samples were collected pre- and post-laparoscopic sleeve gastrectomy (LSG), with the visit intervals divided into four visits: pre-surgery (0M), 3 months (3M), 6 months (6M) and 12 months (12M). Food intake and eating patterns significantly changed during the first year (P < 0·001). The mean energy intake at 3M post-surgery was 738·3 kcal, significantly lower than the pre-surgery energy intake of 2059 kcal. Then, it increased gradually at 6M and 12M to reach 1069 kcal (P < 0·00). The intake of Fe, vitamin B12 and vitamin D was below the dietary reference intake recommendations, as indicated by the 24-hour dietary recall. The prevalence of 25 (OH) vitamin D deficiency improved significantly from pre- to post-surgery (P < 0·001). Vitamin B12 deficiency was less reported pre-LSG and improved steadily towards a sufficient post-surgery status. However, 35·7 % of participants were deficient in Fe status, with 28·6% being female at higher levels than males. While protein supplementation decreased significantly over the 12M follow-up, the use of vitamin supplements dramatically increased at 3 and 6M before declining at 12M. Fe and vitamin B12 were the most popular supplements after vitamin D. This study confirms the necessity for individualised dietary plans and close monitoring of candidates' nutritional status before and after bariatric surgery.

Validation of DEQ-5 unidimensionality and differential item functioning of Saudi adult populations

Objective: The Dry Eye Questionnaire (DEQ-5) is a questionnaire for dry eyes vital for assessing ocular surface disease severity in dry eye disease (DED). This analysis aimed to comprehensively evaluate its precision, reliability, unidimensionality, and differential item functioning (DIF) irrespective of age and gender. Methods: This cross-sectional research was carried out between March 2021 and March 2022. A systematic random sampling technique selected participants (n=634). The DEQ-5 questionnaire was used in the King Saud University campus clinic and Kingdom Hospital in Riyadh, Saudi Arabia. Statistical analysis was performed using statistical software (SPSS version 28 SPSS Inc., Chicago, IL; for Windows). Standard deviations (SDs), percentages, and averages are used to show the data reliability analysis to test Cronbach's coefficient, which calculated the scale's internal consistency, McDonald's coefficient, and item-rest correlations. Moreover, Rasch Analysis has been performed to check if the DEQ-5 can distinguish different levels of dry eye symptoms. Results: The study revealed that the DEQ-5 performed well in various aspects. At 2, the person separation index (PSI) was satisfactory, indicating good reliability (0.80). Items separation revealed outstanding reliability (1.00), with mean square data for attire and infit within acceptable ranges (0.545-1.674 and 0.578-1.698, respectively). The high-reliability precision (77%) suggests the questionnaire's ability to elicit accurate responses. The analysis confirmed unidimensionality; the first contrast's eigenvalue for unexplained variance is less than 2 (1.79). DIF analysis stratified by age showed that participants aged 16-26 performed better on @3QUESTION than those aged 27-40. Similarly, based on gender, males outperformed females in @1B and @2QUESTION. Furthermore, with a Cronbach's coefficient of 0.767 and a McDonald's coefficient of 0.828, the DEQ-5 demonstrated adequate internal consistency, reaffirming its reliability. Conclusions: The DEQ-5 is a robust instrument for evaluating DED severity, as evidenced by its acceptable precision, reliability, unidimensionality, and DIF analysis results. Understanding its performance across different age and gender groups provides valuable insights for its use in clinical and research settings, ensuring accurate assessment and diagnosis of DED.

Emergency consultations to pediatric dermatology at a large children’s hospital in Saudi Arabia

Dermatology is commonly considered a non-urgent and outpatient-centered specialty. Limited studies have evaluated skin diseases presenting to the pediatric emergency department. This study aims to characterize the most common pediatric dermatological conditions prompting an emergency department visit between August 2018 and August 2023 in a large children’s hospital in Riyadh, Saudi Arabia. A total of 183 patients were included. The majority of patients were 2 years old and younger [87 (47.5%)]. Gender was almost equally distributed, with 51.4% of the population being females. Infectious and inflammatory disorders were the most commonly encountered conditions, accounting for 35.5% and 33.9%, respectively. The top three diagnoses were atopic dermatitis (12.02%), impetigo (6.56%), and infantile hemangioma (6.01%). Understanding the variety of skin disorders presented to pediatric emergency departments can positively enhance patient care in dermatology clinics and promote preventative public health initiatives, thus minimizing emergency department visits.

Mpox outbreak in a cluster of hospitals at Riyadh, Saudi Arabia 2022-2023: clinical presentation, risk factors, and preventive measures.

This study investigated the Mpox outbreak that occurred in a health cluster of three hospitals in Riyadh, Saudi Arabia, involving 97 patients diagnosed between May and December 2023. Among them, 48% were Saudi nationals, 94% were men, and 73% were under 35 years old. While sexual activity was a potential transmission mode, only 38% of patients reported it. All patients were presented with skin lesions and common symptoms like fever, headaches, and itching, with two being HIV positive. Genotyping revealed all samples were from subclade IIb (West Africa clade). Unlike previous outbreaks, rashes and systemic symptoms emerged simultaneously without a prodromal phase. Stringent infection control measures kept healthcare workers safe, although underreporting of sexual behavior may limit the study's findings. This highlights the need for Mpox consideration in young individuals with skin lesions.

Burden, Anxiety, and Depression Among Caregivers of Parkinson's Disease Patients.

Parkinson's disease (PD) is a disabling neurodegenerative movement disorder. Most PD patients are looked after by caregivers who are close to them regardless of their relationship. Caregivers may experience a notable impact on their mental health as they dedicate a significant amount of time to the patient while observing the progression of the disease. The aim of this study was to evaluate the level of burden, depression, anxiety, and stress among caregivers of PD patients. We conducted a cross-sectional analysis between July and September 2023 among caregivers of PD patients following in the Movement Disorders Clinic at King Khalid University Hospital in Riyadh, Saudi Arabia, and through the Saudi Parkinson's Society. The data collection was done anonymously through an electronic self-administered questionnaire. Caregiver burden was assessed by using the validated Arabic version of the Zarit Burden Interview (ZBI) scale, and the Depression Anxiety Stress Scale (DASS) was used to assess the presence and level of anxiety and depression. There were 118 caregivers (53.39% female, 33.9% aged between 35- 45 years, and 73.73% were sons/daughters) caring for 118 patients (57.63%, male, 38.98% aged between 66- 76). The ZBI score was highest among sibling caregivers. Moreover, burden scores were higher among those who provided care more frequently than others. Our study revealed that PD caregivers face a high risk of care burden, especially those who are siblings and spend longer periods in patient care. Additionally, female caregivers reported higher rates of depression, anxiety, and stress.

Prevalence and Antimicrobial Susceptibility Patterns of Wound and Pus Bacterial Pathogens at a Tertiary Care Hospital in Central Riyadh, Saudi Arabia

The long history and extensive use of antibiotics have caused resistant bacterial pathogens to emerge, increasing mortality and morbidity. The current study was designed to see the prevalence of aerobic bacterial isolates with their antimicrobial resistance pattern from out- and inpatients requested for wound or pus culture. Retrospective study conducted at a tertiary care hospital in central Riyadh from January 2023 to December 2023. Samples were collected and inoculated onto the appropriate media following standard guidelines. Bacterial pathogens were identified by the Vitek2 compact system. Antimicrobial susceptibility was tested using the Kirby–Bauer disk diffusion method as well as by MIC determination through the Vitek2 compact. A total of 1186 subjects were included in the study with a bacterial isolation rate of 691 (58.3%). Out of these, 155 positive cultures had incomplete information or anaerobic or fungal growth and were excluded from the study. With a slight female predominance (54.9%), the majority of subjects (72.2%) were outpatients, and over half of the isolates (55.2%) were Gram-positive. The most common isolate was Staphylococcus spp. (44.4%), followed by E. coli (13.6%) and P. aeruginosa (12.9%). The highest resistance was reported against penicillin followed by fusidic acid against Gram-positive bacteria. Methicillin-resistant Staphylococcus aureus (MRSA) was detected in 40.5% of Staphylococcus aureus (S. aureus) isolates. Amikacin was the most susceptible antibiotic against all Gram-negative isolates. MDR Gram-negative bacteria accounted for 51.9% of wound infection isolates (95% CI: 45.95 to 58.33) while 6.3% (95% CI: 4.39 to 8.86) were XDR (nonsusceptibility to at least one agent in all but two or fewer antimicrobial categories). A high prevalence of bacterial isolates, with S. aureus as the predominant pathogen, showed high rates of multidrug resistance. This highlights the importance of monitoring antibiotic choices for prophylaxis and treatment in the study area.

Consanguinity and Occurrence of Monogenic Diseases in a Single Tertiary Centre in Riyadh, Saudi Arabia: A 2 Years Cross-Sectional Study.

Consanguinity, or the practice of marrying close relatives, is a common cultural tradition in Saudi Arabia, with rates among the highest in the world. This practice has significant implications for the prevalence and distribution of major single genetic defects and chromosomal abnormalities within the Saudi population. Herein, using the BESTCare electronic medical record system (designed to streamline hospital operations, enhance patient care, and improve the overall efficiency of healthcare services; bestcare.ezcaretech.com) in a single tertiary centre, King Abdullah Specialized Children Hospital (KASCH) in Riyadh, Saudi Arabia, we performed a cross-sectional study for all patients referred to the hospital from the 1st January 2020 until 1st January 2022. The present study, which included 1100 individuals, found a high prevalence of consanguinity (64%) and a significant proportion of third-degree relatives (69%). The mean age of participants was 12.24 years, and the diagnostic rate using advanced molecular genetics techniques was 45%, with whole exome sequencing (WES) being the most common method (43%). The study also noted a significant delay in diagnosis for more than a year in 16% of cases, with a common neurodevelopmental phenotype (18%). In conclusion, we revealed the prevalence of consanguineous marriages in the KASCH hospital in Riyadh, Saudi Arabia. We also highlighted the most frequently referred phenotype. These findings are consistent with previous research on the prevalence and impact of consanguinity on rare genetic disorders.

Exploring online health resources and self-care among irritable bowel syndrome patients: analyzing internet use and AI chatbot interactions.

The increasing prevalence of irritable bowel syndrome (IBS) in Saudi Arabia has led to a growing interest in understanding how patients seek health information online. While it is known that digital platforms, such as search engines, social media, and artificial intelligence (AI) chatbots, are commonly used for health information seeking, there is limited knowledge about the specific behaviors of IBS patients in this context and how these behaviors correlate with their self-care activities. This study aimed to explore online health information-seeking behavior and its correlation with self-care activities among patients with IBS in Saudi Arabia, focusing on the use of these digital platforms. A cross-sectional survey was conducted at King Khalid University Hospital in Riyadh, Saudi Arabia, from January to July 2023. The survey, available in both English and Arabic, targeted IBS patients aged 16 years or older. The questionnaire covered demographics, general internet usage, online health information-seeking behavior, and IBS knowledge and awareness. In this study, 451 IBS patients completed the survey. Notably, 95.1% of participants were internet users, primarily accessing health information through mobile phones and search engines. The results highlighted a significant correlation between online health information-seeking behaviors and self-care practices (P=0.009) like exercise and dietary adjustments, despite a moderate basic knowledge [standard deviation (SD) 2.26%] of IBS. Symptomatically, 93.3% experienced abdominal pain weekly, yet 63% did not fully meet the Rome criteria for IBS. Common management strategies included hydration, diet modifications, and exercise. About 28.4% visited the emergency room (ER) for severe symptoms, and 20% regularly consulted doctors every 3-6 months. Surprisingly, 80% were unaware of the FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) diet, often suggested for IBS. The research indicates a rise in digital health literacy among IBS patients in Saudi Arabia, highlighting the need for accurate and culturally appropriate online resources. It suggests that healthcare professionals and policymakers should direct patients to reliable information and address the digital divide to enhance self-care and IBS management outcomes.

Risk factors and characteristics of intraoperative pressure injuries caused by medical devices and adhesives: A case-control retrospective study

Background: Undesirable injuries during the intraoperative period, such as pressure injuries caused by improper positioning, medical devices, or adhesive tapes, can lead to patient harm and decreased satisfaction. This study aims to identify the risk factors of pressure injuries during the intraoperative period and the characteristics of these injuries. Methods: A retrospective case-control study was conducted at King Khaled University Hospital in Riyadh, Saudi Arabia. Data were collected from the hospital incident reporting system and electronic medical records for incidents reported from January 1, 2022 to December 31, 2022. Inclusion criteria consisted of all patients with a reported pressure injury, including pressure ulcers, medical adhesive-related skin injuries, or medical device-related pressure injuries, occurring at least once during surgery. Results: Among the 113 patients, 57 (50.44%) had intraoperative pressure injuries (cases), while 56 (49.56%) did not (controls). The most common locations for pressure injuries were the lips (33.33%). Most of these injuries were classified as Medical Adhesive-Related Skin Injury (61.40%). Stage 1 injuries were observed in 47 cases (82.46%), while Stage 2 injuries were observed in 10 cases (17.54%). Duration of surgery and device tightness were identified as significant risk factors (P &lt; 0.001). Conclusion: This case-control study identified the duration of surgery and device tightness as significant risk factors for intraoperative pressure injuries. The findings emphasize the importance of implementing evidence-based prevention strategies. Healthcare professionals should prioritize staff education and training, while future research should focus on conducting prospective, multicenter studies and developing risk assessment tools and innovative medical devices.

Assessment of the effectiveness of hospital external disaster functional drills on health care receivers’ performance, using standardized patients and mass cards simulation: a pilot study from Saudi Arabia

BackgroundGiven the increasing frequency of disasters globally, it is critical that healthcare systems are prepared for these mass casualty events. The Saudi health system’s preparedness for mass casualty incidents needs to be more robust, potentially due to limited disaster drills and inadequate standardized patient (SP) simulation training. This study aims to (i) assess the performance of front-line hospital staff in Saudi Arabia through a functional drill and (ii) evaluate the drill’s effectiveness using SP and MAC-SIM cards, providing detailed insights into its design and execution.MethodsA functional drill was conducted at a government hospital in Riyadh, Saudi Arabia, on December 19, 2022, using a cross-sectional approach with two phases. 141 healthcare receivers served as subjects, while 23 volunteers acted as SPs. The scenario simulated a building collapse to assess the emergency department (ED) response, interdepartmental communication, and surge capacity. Data were collected through direct observation of healthcare practitioners’ interactions with the SPs, analysis of SP data, and participant feedback. Quantitative data were analyzed descriptively, while qualitative data were examined for patterns and themes related to simulation performance and effectiveness.ResultsThe hospital receivers’ performances demonstrated accurate triage categories. The ED team assessed most patients (67%) in less than 5 min. For patients requiring definitive care, such as intensive care unit, 95% spent less than 2.5 h in the ED. Most patients (65%) required ‘other treatments’. Communication was efficient in the triage zone and the yellow treatment area. Participants’ feedback on using MAC-SIM cards during the simulation was overwhelmingly positive with 82.61% reporting that MAC-SIM use helped them respond better. Experienced SPs (paramedics) with prior disaster knowledge and experience outperformed inexperienced SPs (nurses) in the functional exercise.ConclusionThis groundbreaking study is the first in the Arabic Gulf region to use SPs with MAC-SIM cards in functional drills. The findings highlight the potential of simulation exercises to improve hospital team knowledge and performance when responding to disasters. Multiple evaluation techniques can effectively identify participant strengths and weaknesses, informing future disaster improvement plans. This information is a valuable resource for Arabic and middle-income countries where disaster medicine is still developing.

Patients with influenza admitted to a tertiary-care hospital in Riyadh between 2018 and 2022: characteristics, outcomes and factors associated with ICU admission and mortality

BackgroundInfluenza is a common cause of hospital admissions globally with regional variations in epidemiology and clinical profile. We evaluated the characteristics and outcomes of patients with influenza admitted to a tertiary-care center in Riyadh, Saudi Arabia.MethodsThis was a retrospective cohort of adult patients admitted with polymerase chain reaction-confirmed influenza to King Abdulaziz Medical City-Riyadh between January 1, 2018, and May 31, 2022. We compared patients who required intensive care unit (ICU) admission to those who did not and performed multivariable logistic regression to assess the predictors of ICU admission and hospital mortality.ResultsDuring the study period, 675 adult patients were hospitalized with influenza (median age 68.0 years, females 53.8%, hypertension 59.9%, diabetes 55.1%, and chronic respiratory disease 31.1%). Most admissions (83.0%) were in the colder months (October to March) in Riyadh with inter-seasonal cases even in the summertime (June to August). Influenza A was responsible for 79.0% of cases, with H3N2 and H1N1 subtypes commonly circulating in the study period. Respiratory viral coinfection occurred in 12 patients (1.8%) and bacterial coinfection in 42 patients (17.4%). 151 patients (22.4%) required ICU admission, of which 62.3% received vasopressors and 48.0% mechanical ventilation. Risk factors for ICU admission were younger age, hypertension, bilateral lung infiltrates on chest X-ray, and Pneumonia Severity Index. The overall hospital mortality was 7.4% (22.5% for ICU patients, p < 0.0001). Mortality was 45.0% in patients with bacterial coinfection, 30.9% in those requiring vasopressors, and 29.2% in those who received mechanical ventilation. Female sex (odds ratio [OR], 2.096; 95% confidence interval [CI] 1.070, 4.104), ischemic heart disease (OR, 3.053; 95% CI 1.457, 6.394), immunosuppressed state (OR, 7.102; 95% CI 1.803, 27.975), Pneumonia Severity Index (OR, 1.029; 95% CI, 1.017, 1.041), leukocyte count and serum lactate level (OR, 1.394; 95% CI, 1.163, 1.671) were independently associated with hospital mortality.ConclusionsInfluenza followed a seasonal pattern in Saudi Arabia, with H3N2 and H1N1 being the predominant circulating strains during the study period. ICU admission was required for > 20%. Female sex, high Pneumonia Severity Index, ischemic heart disease, and immunosuppressed state were associated with increased mortality.

Clinical and genetic evaluation of hereditary myopathies in an adult Saudi cohort

BackgroundDiagnosis of hereditary myopathy is often challenging owing to overlapping clinical phenotypes and muscle histopathological findings. This retrospective study aimed to identify the phenotypic and genotypic spectra of hereditary myopathies at a tertiary hospital in Riyadh, Saudi Arabia.MethodsWe reviewed the medical records of patients with hereditary myopathy who were evaluated between January 2018 and December 2022.ResultsEighty-seven patients (78 families) were included, two-thirds were men with a mean age of 35 (SD 14.2) years. Limb-girdle muscular dystrophy (LGMD) was the most prevalent clinical diagnosis (25 cases; 29%), of whom, a genetic diagnosis was achieved in 15 of 22 patients tested (68%). In genetically confirmed LGMD, the most prevalent disorders were dysferlinopathy (27%) followed by fukutin-related protein (FKRP) - related limb girdle muscular dystrophy (20%), sarcoglycanopathy (20%), lamin A/C related myopathy (13%), and calpain-3 myopathy (13%). In 26 patients with pathogenic/likely pathogenic variants, the genetic testing method was whole exome sequencing (WES) (42%), Next generation sequencing (NGS) (31%), and targeted single gene analysis (27%). The sensitivity of each genetic testing method was as follows: 100% for targeted single-gene analysis, 100% for targeted analysis of D4Z4 repeat array units, 88% for myotonic dystrophy protein kinase (DMPK) repeat expansion analysis, 42% for NGS-neuromuscular panel, and 46% for WES.ConclusionThe prevalent types of hereditary myopathies were consistent with those reported locally and internationally. This study highlights the diagnostic yield of various molecular genetic tests for the diagnosis of hereditary myopathy in an adult cohort and the need for improved access to advanced molecular testing in cases suspected to have facioscapulohumeral muscular dystrophy (FSHD) or mitochondrial myopathies.

Background: Surgical advancements have led to the development of Enhanced Recovery After Surgery (ERAS) guidelines. This study aims to assess the nurse’s role in improving patient outcomes and healthcare efficiency using ERAS. Methodology: This cross-sectional study was conducted in Aster Sanad Hospital Riyadh, Saudi Arabia. Data were collected using a self-administered questionnaire and from electronic medical records. The study sample was given a self-administered questionnaire. Data were analyzed using the Statistical Package for Social Sciences (SPSS), version 21 (IBM SPSS Statistics, Armonk, NY) to analyze the data. Result: The result shows that there is a significant level of confidence among a notable portion of respondents regarding their understanding of ERAS protocols, there are also areas of uncertainty and variability, indicating the need for targeted interventions to enhance comprehension and implementation. Moreover, there is widespread acknowledgement of the pivotal role of nurses in ERAS implementation, yet significant proportions express reservations about nurses' training, workload constraints, and support from healthcare institutions. Conclusion: Overall, these findings emphasize the multifaceted nature of ERAS implementation, requiring a comprehensive approach that addresses training, communication, workload, and resource allocation to optimize patient outcomes and healthcare efficiency in Cesarean surgery units at Aster Sanad Hospital.

The Impact of Sacubitril/Valsartan on Heart Failure Patient with Reduced Left Ventricular Ejection Fraction: Single Center Retrospective Study in Saudi Arabia.

Sacubitril/valsartan (S/V) is used in managing heart failure with reduced ejection fraction (HFrEF), reducing morbidity and mortality while improving symptoms and prognosis. This study aims to evaluate the effectiveness of S/V in patients with reduced left ventricular ejection fraction (LVEF) and its safety. This retrospective cohort study included adult patients aged ≥18 years diagnosed with HFrEF, receiving S/V, and followed up at a tertiary hospital in Riyadh. Primary outcomes included improvements in LVEF on echocardiography and the number of hospitalizations due to acute decompensated heart failure (ADHF). Secondary outcomes assessed the safety profile of S/V. Multinomial logistic regression analysis was performed with statistical significance set at P < 0.05. . The study included 107 patients: 80 with LVEF < 30% and 27 with LVEF 30-40%. Six-month follow-up, LVEF improvement was categorized into three groups: no improvement, LVEF increased by 1 to <10 points, and LVEF increased by ≥10 points. The LVEF was similar across groups (P = 0.59). Although hospitalizations due to ADHF were not significantly different between groups, they numerically decreased after initiating S/V (P = 0.1). S/V was generally well tolerated. This study suggests no significant benefit from S/V regarding LVEF improvement. It is recommended that heart failure clinics assess and titrate S/V to the maximum tolerated dose.

Impact of Isotretinoin on Blood Lipids and Liver Enzymes: A Retrospective Cohort Study in Saudi Arabia.

Isotretinoin is an effective treatment for acne but can cause side effects such as changes in blood lipids and liver enzymes. Laboratory monitoring is essential during treatment, but there is variation in monitoring practices. This study aims to investigate the relationship between isotretinoin therapy and its effects on complete blood count in Saudi Arabia to improve patient outcomes. The study was a retrospective cohort study conducted at King Khalid University Hospital in Riyadh, Saudi Arabia, between January 2016 and December 2020. Following the inclusion and exclusion criteria, 515 patients were randomly selected for the study. The data was analyzed using SPSS, and descriptive statistics and paired samples t-tests were employed to analyze the data. In this study, 515 patients were enrolled. Of these participants, 76.7% (n=395) were females and 23.3% (n=120) were males. The mean age of the study participants was 23.98±7.4 years and ranged between 16 and 65 years. The mean dose of Isotretinoin administered was 27.65±9.6 mg/day, with a range of 10-60 mg/day. The mean BMI of the study participants was 24.3±4.1 kg/m2, ranging from 14.3 to 44.8 kg/m2. Regarding the effect of Isotretinoin on laboratory measures, significant statistical differences were found in hemoglobin measurements (t=-3.379, p=0.001), platelets (t=-3.169, p=0.002), neutrophils (%) (t=3.107, p=0.002), total cholesterol (t=-13.017, p=0.000), AST (t=-6.353, p=0.000), ALT (t=-4.352, p=0.000), HDL (t=2.446, p=0.015), and LDL (t=-12.943, p=0.000). However, there were no significant statistical differences in the measurements of WBC, neutrophils (count), or triglycerides. In the Chi-square analysis and Fisher's Exact test to identify the interaction between BMI, dose, and gender on abnormal lab results, significant interaction was found between participants' BMI and abnormal HDL measurements (p=0.006). Furthermore, there were significant interactions between Isotretinoin dose (either less than 30 mg/day or 30 mg/day or more) and abnormal neutrophil count (p=0.04), abnormal HDL measurements (p=0.010), and abnormal triglycerides measurements (p=0.020). Moreover, a statistically significant interaction was found between participants' gender and abnormal hemoglobin measurements (p=0.006), abnormal total cholesterol (p=0.016), abnormal AST measurements (p=0.001), abnormal ALT measurements (p=0.000), abnormal HDL measurements (p=0.000), and abnormal triglycerides measurements (p=0.007). In conclusion, the study found that isotretinoin therapy has significant effects on several laboratory measures, including hemoglobin, platelets, neutrophils, total cholesterol, AST, ALT, HDL, and LDL. The study also revealed significant interactions between BMI, dose, gender, and abnormal lab results.

Exploring Patient Preferences for Information About CT Radiation Exposure: Bridging the Gap Between Patient Preference and Physician Practice.

CT scan utilizes ionizing radiation poses a danger to the patient's health. Thus, telling the patient about ionizing radiation would be critical in promoting shared decision-making and improving patient-doctor communication. However, few studies have examined this topic broadly. The study was conducted to identify the frequency of physicians informing patients about the radiation risk before ordering a CT scan, as well as to examine the association between patients' demographic characteristics and their awareness of the radiation risks associated with CT scans. A cross-sectional study was conducted among 387 patients who had undergone CT scans at a tertiary hospital in Riyadh, Saudi Arabia. Data were collected via phone interviews using a structured questionnaire. Chi-squared tests were employed to assess associations between patients' demographic characteristics and their awareness of CT scan radiation risks. When examining knowledge, 58% of patients knew that CT involves harmful radiation. This knowledge was significantly associated with higher education level and previous experience with CT scans. Regarding doctors' practice of providing information to patients about the scan, 344 (88.9%) patients indicated that their doctor had explained to them why they needed the scan. Only 28 (7.2%) patients stated that their doctor had mentioned the amount of radiation, and 74 (19.1%) patients indicated that doctors mentioned the risks associated with the radiation of the scan. Almost all patients (96.9%) preferred to be told about why they needed a CT scan. The vast majority of patients who underwent CT scans did not receive enough information about the harm of the scans. However, most of them preferred to know about this harm.

First report of the clinical characteristics and outcomes of cardiac amyloidosis in Saudi Arabia.

Cardiac amyloidosis (CA) is a potentially fatal multisystemic disease that remains significantly underdiagnosed, particularly in the Middle East. This study aims to evaluate the prevalence and clinical characteristics of CA in a high-risk population at a tertiary centre in Saudi Arabia. This cross-sectional, retrospective, single-centre study was conducted at a tertiary hospital in Riyadh, Saudi Arabia. We reviewed the medical records of heart failure patients seen between August 2018 and July 2022 who exhibited red flags for CA and subsequently underwent CA screening. Red flags that prompted the workup included at least two of the following factors: the presence of unilateral or bilateral carpal tunnel syndrome, a family history of transthyretin amyloid (ATTR) amyloidosis and specific electrocardiographic features (relative/absolute low QRS voltage, pseudoinfarct pattern and atrioventricular/interventricular conduction abnormalities). Echocardiographic red flags included mainly increased wall thickness (≥12mm), significant diastolic dysfunction, reduced left ventricular (LV) longitudinal function, right ventricular (RV) dysfunction and elevated right atrial (RA)/pulmonary artery (PA) pressure. Cardiac magnetic resonance (CMR) red flags included aspects similar to those in an echocardiogram as well as a subendocardial or transmural late gadolinium enhancement (LGE) pattern. These patients were assessed for CA through technetium-99m pyrophosphate ([99mTc]Tc-PYP) bone scintigraphy, serum and urine protein electrophoresis with immunofixation and a serum-free light chain assay. A total of 177 patients were screened, of which 21.0 (11.9%) patients were diagnosed with transthyretin amyloid CA (ATTR-CA) and 13 (7.3%) patients were diagnosed with light chain CA (AL-CA). Compared with patients with negative/equivocal [99mTc]Tc-PYP scans (grades 0-1), patients with positive [99mTc]Tc-PYP scans (grades 2-3) were older (78.0 vs. 68.0years, P<0.001), had higher levels of troponin (P=0.003) and N-terminal pro-brain natriuretic peptide (NT-proBNP) (P<0.001), had a higher LV mass index (P<0.001), displayed a more depressed global longitudinal strain (GLS) (P<0.001) with a greater prevalence of a relative apical sparing pattern (P<0.001) and demonstrated a higher incidence of first-degree atrioventricular block (P=0.008) and low voltage patterns on electrocardiography (P<0.001). Patients with ATTR-CA and AL-CA were more likely to have a subendocardial or transmural LGE pattern on CMR (P<0.001) and had a significantly lower overall survival (P<0.001) when compared with other heart failure aetiologies. This is the first study to describe the clinical characteristics and outcomes of CA in the Middle East and Saudi Arabia. The prevalence of CA among screened heart failure patients here aligns with major international studies, suggesting significant underdiagnosis in the region. Therefore, larger multicentric studies and regional screening programmes are urgently needed to accurately characterize the epidemiology and outcomes of CA in the Middle East.

Does Tranexamic Acid Administration Increase the Risk of Thromboembolism?

Introduction Hemorrhage following trauma is one of the leading causes of death worldwide. Venous thromboembolism (VTE) is a common complication of an increased coagulable state, and the risk of VTE following the administration of tranexamic acid (TXA), an antifibrinolytic agent, is still controversial. Our aim is to understand whether there is any association between the administration of TXA and the risk of VTE development. Methods A retrospective cohort study enrolled trauma patients presenting to a level 1 trauma center who received TXA at King Abdulaziz Medical City (KAMC), a tertiary hospital in Riyadh, Saudi Arabia, between 2016 and 2020. Variables included were patients' demographics, comorbidities, laboratory investigations, TXA's route of administration, date of administration, and dose. Finally, the development of VTE in the form of deep vein thrombosis (DVT) or PE and those who died were evaluated. Results A total of 361 adult trauma patients who received TXA were included in the study. Most were males (90.3%) with an average age of 33 years and had a normal BMI(43.3%). Nine patients (2.5%) developed DVT, one of whom died, and five patients (1.4%) developed PE, with no recorded deaths. Conclusion The risk of VTE following the administration of TXA remains controversial and yet to be clearly demonstrated. In this study, there was no significant association between TXA administration and the risk of developing VTE. More research with a larger sample size is needed to identify and recognize any significant risk factors for developing such a condition.
