Significance of Scapular Fracture Existence in Blunt Chest Trauma: A Retrospective Cohort Study.

Background: Scapular fracture is a rare encounter in blunt trauma patients. The scapula is surrounded by strong groups of muscles offering good protection for the bone. Therefore, a high-energy trauma is needed to cause a scapular fracture. We aim to study scapular fractures and their relation to injury severity and mortality in blunt chest trauma (BCT) patients. Methods: We retrospectively collected data from all patients with BCT who were admitted to our hospital from December 2014 through January 2017. The injury details of all BCT patients were retrieved from the trauma registry of the hospital and were supplemented by patients' electronic files for missing information. Collected data included demography, mechanism of injury, vital signs, Glasgow Coma Score (GCS) on admission, injured body regions, management, Injury Severity Score (ISS), New Injury Severity Score (NISS), length of hospital stay (LOS), and mortality. Results: During the study period, 669 patients had BCT. Scapular fracture was present in 29 (4.3%) of the BCT patients. The scapular fracture was missed by chest X-ray in 35.7% of the patients; however, it was accurately diagnosed by computed tomography (CT) scan of the chest. Neck injury was significantly higher in patients with scapular fracture compared with patients without fracture (p < 0.001). ISS and NISS were significantly higher in patients with scapular fractures compared to other patients without fractures (p=0.04 and p=0.003 Mann-Whitney U test, respectively). Two patients with scapular fractures died due to severe associated injuries (the overall mortality was 9.6%). Conclusions: Scapular fracture in BCT patients indicates a high-energy type of trauma. Compared to a chest X-ray, CT scan was more accurate for the diagnosis of scapular fracture. Associated injuries are the main cause of trauma-related mortality rather than the direct effect of the fractured scapula. Particular attention and meticulous evaluation should be paid to head and neck injuries to avoid missing injuries.

Measurement properties of the Mental Health Literacy Scale (MHLS) validation studies: a systematic review protocol.

INTRODUCTION: Mental Health Literacy (MHL) is important for improving mental health and reducing inequities in treatment. The Mental Health Literacy Scale (MHLS) is a valid and reliable assessment tool for MHL. This systematic review will examine and compare the measurement properties of the MHLS in different languages, enabling academics, clinicians and policymakers to make informed judgements regarding its use in assessments. METHODS AND ANALYSIS: The review will adhere to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology for systematic reviews of patient-reported outcome measures and the Joanna Briggs Institute (JBI) Manual for Evidence Synthesis and will be presented following the Preferred Reporting Items for Systematic reviews and Meta-Analysis 2020 checklist. The review will be conducted in four stages, including an initial search confined to PubMed, a search of electronic scientific databases PsycINFO, CINAHL, Scopus, MEDLINE, Embase (Elsevier), PubMed (NLM) and ERIC, an examination of the reference lists of all papers to locate relevant publications and finally contacting the MHLS original author to identify validation studies that the searches will not retrieve. These phases will assist us in locating studies that evaluate the measurement properties of MHLS across various populations, demographics and contexts. The search will focus on articles published in English between May 2015 and December 2023. The methodological quality of the studies will be evaluated using the COSMIN Risk of Bias checklist, and a comprehensive qualitative and quantitative data synthesis will be performed. ETHICS AND DISSEMINATION: Ethics approval is not required. The publication will be in peer-reviewed journals and presented at national and international conferences. PROSPERO REGISTRATION NUMBER: CRD42023430924.

Adolescents' use of online food delivery applications and perceptions of healthy food options and food safety: a cross-sectional study in the United Arab Emirates.

Introduction: This cross-sectional study aimed to assess Online food delivery applications (OFDA) usage trends among adolescent users in the United Arab Emirates (UAE), focusing on their perceptions of healthy food options and food safety (n = 532). Methods: Sociodemographic information, frequency of OFDA use, factors affecting food choices, and perceptions of healthy food and food safety were investigated. A total perception score was calculated for each participant. Results: Most participants used OFDAs weekly (65.4%), favoring fast food (85.7%). Factors like appearance and price drove food choices (65.0%), while taste and cost hindered healthy food orders (29.7 and 28.2%). Younger and frequent users had lower scores for perceiving healthy food, while seeking healthy options was associated with higher scores (p < 0.05). Females and those seeking healthy food showed higher food safety scores (p < 0.05). Discussion: The study suggests tailored interventions to promote healthier choices and improve food safety perceptions among adolescents using OFDAs in the UAE.

Durability of COVID-19 humoral immunity post infection and different SARS-COV-2 vaccines.

BACKGROUND: The global challenge posed by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has been a major concern for the healthcare sector in recent years. Healthcare workers have a relatively high risk of encountering COVID-19 patients, making protective immunity against SARS-CoV-2 is a priority for them. This study aims to evaluate the longitudinal measurement of SARS-CoV-2 IgG spike protein antibodies in healthcare workers (HCWs) after COVID-19 infection and after receiving the first and second doses of SARS-CoV-2 vaccines, including Pfizer-BioNTech (BNT162b2) and Oxford-AstraZeneca (AZD1222). METHODS: This longitudinal cohort study involved 311 healthcare workers working in two tertiary hospitals in Saudi Arabia. All participants were followed between July 2020 and July 2022 after completing the study questionnaire. A total of 3 ml of the blood samples were collected at four intervals: before/after vaccination. RESULTS: HCWs post-infection had lower mean SARS-CoV-2 IgG levels three months post-infection than post-vaccination. 92.2% had positive IgG levels two weeks after the first dose and reached 100% after the second dose. Over 98% had positive antibodies nine months after the second dose, regardless of vaccine type. The number of neutralizing antibodies decreased and was around 50% at nine months after the second dose. CONCLUSION: The results show different antibody patterns between infected and vaccinated HCWs. A high proportion of participants had positive antibodies after vaccination, with high levels persisting nine months after the second dose. Neutralizing antibodies decreased over time, with only about 50% of participants having positive antibodies nine months after the second dose. These results contribute to our understanding of immunity in healthcare workers and highlight the need for the continuous monitoring and possible booster strategies.

Prevalence of adverse childhood experiences and their cumulative impact associated lifetime health outcomes in the Emirate of Abu-Dhabi, United Arab Emirates.

BACKGROUND: Adverse Childhood Experiences have been associated with poor health outcomes later in life. OBJECTIVE: The objective of the study was to determine the relationship between cumulative ACEs, risky health behaviors, chronic diseases, and mental health among a large-scale sample from the Emirate of Abu Dhabi. PARTICIPANTS AND SETTING: A retrospective cross-sectional study was performed with 922 participants over the age of 18, living in Abu Dhabi. METHODS: The Adverse Childhood Experiences International Questionnaire (ACE-IQ) was used to assess ACEs, alongside a survey of adult health outcomes, mental health outcomes, and risk-taking behaviors. RESULTS: Logistic regression models examined the association between retrospective ACEs and these outcomes. The respondents reported an average of 1.74 ACEs. The most prevalent ACEs were household violence, parental death or divorce, and community violence. The accumulation of ACEs significantly predicts increases in the risk of a variety of adult-onset health morbidities, all measured mental health morbidities, and all measured risk-taking behaviors, with evidence of thresholds of ACE accumulation dictating risk. CONCLUSIONS: The baseline presence of ACEs among this Abu Dhabi sample, along with the associated risks of physical and mental health morbidities, and risk-taking behaviors play a significant role in understanding the extent, nature, and associated sequalae of ACEs in this population; providing nuanced context for early intervention. Our findings will inform the planning and implementation of specific prevention and awareness raising programs while promoting safe environments where children are healthy and can thrive.

Collecting behavioral evidence from a highly mobile and seasonal population: A protocol for a survey on quad bike injuries.

BACKGROUND: Quad bikes are popular recreational, four-wheeled bikes in the Middle East. Injury prevention programs targeting quad bike crashes in the United Arab Emirates (UAE) need evidence about the risk factors and behaviours associated with these crashes in the target population. This is a protocol for a study aiming to investigate quad bike rider behaviours and to assess the risk factors associated with related injuries in the UAE. METHODS: This is a cross-sectional observational study aiming to describe a seasonal sport in a desert environment. With an estimated sample size of 451, the survey will follow a three-stage, location-based sampling strategy using the line-transect method. A sampling frame of desert locations with high injury incidences was developed, using Dubai ambulance injury records. Further expansion of the sampling frame was participatory, involving police, enthusiasts, emergency responders and gas station employees. The data collection will be limited to the winter months in fifteen high-injury desert locations across three major Emirates in the UAE. Trained researchers will observe the riders directly in the desert to note their riding habits, followed by a researcher-administered interview on riding and injury history. The interviews will be administered in Arabic and English using Qualtrics software on handheld tablets with offline and online entry mode. In addition, paper-based entry with the same format will be used as a contingency in busy quad bike locations. CONCLUSION: The objective of this study protocol is to develop a comprehensive survey that will furnish substantial evidence for the formulation of effective injury prevention strategies. To enhance the credibility of the recorded riding behaviors, field observations will be employed. The uniqueness of this study lies in its innovative sampling strategy, custom-tailored to accommodate the highly mobile and transient population of desert bikers in the UAE.

Breast Cancer in Young Women: Is It Different? A Single-Center Retrospective Cohort Study.

Introduction: Breast cancer (BC) is one of the commonest cancers among women worldwide. Differences regarding tumor biology, presentation, genetics, and molecular subtypes may contribute to the relatively poorer prognosis among younger women. Limited information exists regarding pathologic characteristics and long-term outcomes among this group. Methods: This retrospective cohort study included 695 BC patients diagnosed over a 10-year period and investigated the clinicopathological characteristics and long-term disease outcomes among patients diagnosed at age less than or equal to 40 years compared with older ones. Cox regression analysis was performed, and Kaplan-Meier curves were generated to assess overall survival (OS). Results: Compared with the younger patients (⩽40 years) estrogen receptor (ER) and progesterone receptor (PR) expression was mainly positive in older patients (>40 years) (76.2% vs 61.3% and 64.2% vs 49.6%, respectively). The most common molecular subtype in both age groups was luminal B (44.1% in older and 40.3% in younger). A clinical complete remission after neoadjuvant therapy was observed more frequently in older patients (76.7%; N = 442) in comparison with the younger patients (66.4%; N = 79) (P = .018). Recurrence and disease progression were significantly more likely to occur among younger patients accounting for 12.6% and 29.4% of the cases, compared with 6.3% and 18.2% in older patients (P = .016 and P = .006, respectively). The overall mortality was 132 (19%) of 695, with 88% cancer-related deaths. Estrogen receptor and PR expression (P ⩽ .001 and P = .003, respectively), molecular subtype (P = .002), tumor grade (P = .002), and N stage (P = .038) were the variables that were found to be significantly influenced by age. The OS was not statistically different among 2 age groups, but younger patients with luminal A molecular subtype showed significantly poor outcome (P = .019). Conclusion: Overall survival in women diagnosed with BC at age less than or equal to 40 years is not significantly worse than older patients. However, among patients with luminal A subtype, younger women had relatively poor survival. Further research is needed to understand this age-based disparity in outcomes.

Returning to Work After Traumatic Spine Fractures: Current Status in a Military Hospital.

INTRODUCTION: The consequences of traumatic spine fracture (TSF) are complex and have a major burden on patients' social life and financial status. In this study, we aimed to investigate the return to work (RTW) after surgically treated TSFs, develop eventual predictors of delayed or failure to RTW, and assess narcotics use following such injuries. METHODS: This was a single-center retrospective cohort study that was performed in a tertiary care center. TSF patients who required surgical intervention from 2016 to 2021 were enrolled. Demographic, operative, and complication data, as well as narcotics use, were recorded. RTW was modeled using multivariate logistic regression analysis. RESULTS: Within the 173 patients with TSF, male patients accounted for 82.7%, and motor vehicle accidents were the most common mechanism of injury (80.2%). Neurologically intact patients represented 59%. Only 38.15% returned to work after their injury. Majority of the patients didn't use narcotics more than 1 week after discharge (93.1%). High surgical blood loss, operation time, and hospital length of stay were significantly associated with not returning to work. In multivariant regression analysis, every increase of 100 ml of surgical blood loss was found to decrease the chance of RTW by 25% (P = 0.04). Furthermore, every increase of one hour in operation time decreases the chance of RTW by 31% (P = 0.03). CONCLUSION: RTW is an important aspect that needs to be taken into consideration by health care providers. We found that age and high surgery time, blood loss, and hospital stay are significantly impacting patients' RTW after operated TSF.

Association of the Academic Performance of Undergraduate Medical Students With Positive Well-Being, Intelligence, and Factors of Academic Success.

BACKGROUND: The academic performance of medical students may affect their competence in future career prospects. Developing students' subjective well-being to improve academic performance is complex and has been investigated for many years. This cross-sectional study assessed the relationship between academic performance, general intelligence, and medical students' positive well-being. METHODS: This cross-sectional, internet-based survey included male and female medical students from pre-clinical and clinical years at one of the largest public-sector universities in Riyadh, Saudi Arabia, between February 2020 and April 2020. The questionnaire included the World Health Organization-Five (WHO-5) Well-being Index, the Draw-A-Person Intellectual Ability (DAP: IQ) Test, and the Academic Success Inventory for College Students (ASICS). Academic performance was represented by a self-reported high-grade point average (GPA). Logistic regression was used to assess the association between academic performance and each of the well-being scores, intelligence, and academic success factors. Statistical significance was established at a p-value less than 0.05. RESULTS: Responses were received from 176 medical students. Most participants were males (93.8%). There was a significant association between GPA above 4.5 and the total WHO-5 well-being score (p = 0.013), the ASICS general skills (p = 0.007), perceiving instructor efficacy (p = 0.005), confidence (p < 0.001), personal adjustment (p = 0.023), and lack of anxiety (p = 0.006). No association was found between GPA and intelligence quotient (IQ) or well-being when other factors were adjusted. CONCLUSIONS: Good academic performance is associated with subjective well-being and domains of academic success, such as perceived efficacy of the instructor, confidence, and personal adjustment. Implementing student development programs in medical schools can have a positive impact on students' academic performance and skills. Future studies assessing the different student support and development programs and their impact on academic success are needed.

Correlation analysis between cytokines' profile, autoimmune antibodies and the duration of type 1 diabetes: A case control study in a specialized children's centre in Riyadh.

OBJECTIVE: The aim of this study was to investigate the role of cytokines in children with T1D living in Saudi Arabia and their correlation with disease duration and autoimmune antibody markers. METHODS: A case-control study was conducted in the endocrine clinic of King Abdullah Specialized Children's Hospital in Riyadh. A total of 274 T1D and healthy control children were enrolled in the study. 5 mL of venous blood samples were collected in the morning after 9 to 12 h of fasting in BD Vacutainer® EDTA tubes and centrifuged at 250g for 15 min at. Plasma was then stored at -20°C for detection of anti-islet, anti-GAD antibodies (Abs), and C-peptide using commercial ELISA kits from Thermo Fisher Scientific. The levels of cytokines were measured using commercial sandwich ELISA kits from Abcam. RESULTS: Median differences in cytokine levels (IFN-γ, TNF-α, IL-1ß, IL-2, IL-4, IL-6, IL-10, IL-13, IL-18, IL-21, IL-35, and IL-37) were significantly higher in T1D patients compared with healthy controls (p-value < .001). Spearman's Rho correlation indicated that TNFα, IL-1ß, IL-4, IL-10, IL-13, and IL-21 correlated significantly with T1D Abs (p-value = .01). HbA1C correlated negatively with IL-35 and IL-37, and positively with IL-18 (p-value = .01). Linear regression analysis showed a significant increase in anti-glutamic acid antibodies (GAD) in patients with >3 years of T1D duration. CONCLUSION: Autoantibodies remained positive at high levels in our patients over a 3-year duration of the disease and correlated with specific cytokines. The clear correlations with disease duration and profile of specific cytokines could be targets for future therapeutic interventions.

Lessons Learned From COVID-19 Lockdown: An ASPED/MENA Study on Lifestyle Changes and Quality of Life During Ramadan Fasting in Children and Adolescents Living With Type 1 Diabetes.

Background: Lockdown was a unique experience that affected many aspects of life, particularly during the challenge of Ramadan fasting (RF). Studying this can increase understanding of the effects of lifestyle changes on quality of life (QoL) for children with type 1 diabetes (T1D) during RF. Methods: A cross-sectional study that assessed the effect of lockdown on lifestyle and QoL on fasting children living with T1D during Ramadan in the Middle East and North Africa region (2020-2021). We compared the child (self) and parent (proxy) reports using PEDQoL v3.0 disease specific questionnaire during lockdown and non-lockdown periods, and assessed correlations with lifestyle changes using regression and gap analyses. Results: A total of 998 reports from 499 children with T1D aged 8 to 18 years (study = 276, control = 223), and their parents during RF in lockdown and non-lockdown periods. Fathers were more involved in their children's care during lockdown (P = .019). Patients had better compliance with treatment (P = .002), a reversed sleep pattern (P = .033), increased food intake (P ⩽ .001), and less exercise (P < .001). Children and parents perceived better QoL during lockdown (P ⩽.001) with no differences between their reports in "Diabetes Symptoms", "Treatment Adherence," and "Communication" domains. Self and proxy reports were different in all domains during non-lockdown (P = <.001-.009). In gap analysis, although not statistically significant, the gap was approximated between children's and parents' perceptions in all domains during lockdown. Conclusion: COVID-19 lockdown had a positive impact on QoL of children living with T1D during RF, possibly due to lifestyle changes and superior psychosocial family dynamics.

Knowledge, Attitude, and Practice of Qualitative Research Among Health Sciences Faculty.

Background The importance of qualitative research in health sciences is rising. Qualitative research needs more attention from healthcare practitioners. Hence, some questions in the healthcare field may only be answered through qualitative research methodologies. In this study, we aimed to assess the knowledge, practice, and attitude among health sciences faculty about qualitative research. Methodology This cross-sectional study was conducted at King Saud Bin Abdulaziz University for Health Sciences (KSAU-HS). A convenient sampling technique was used to collect data from health sciences faculty participants. Participants were included from five different colleges, i.e., College of Medicine, Applied Health Sciences, Nursing, Pharmacy, and College of Dentistry. A 20-question, self-made questionnaire was given to each participant. The questionnaire had five attitude questions, 10 knowledge questions, and five practice questions. Results A total of 236 participants completed the study questionnaire. The majority of the study participants (198, 84%) had an overall poor knowledge of qualitative research methodologies. Most participants (214, 91%) agreed that qualitative research is important in health sciences. More than half of the participants had never attended a qualitative methods workshop (140, 59%). About three-quarters of the participants (175, 74%) had never participated in a qualitative research project. Conclusions The overall knowledge and practice of qualitative research methodologies were poor among KSAU-HS health sciences faculty while they had a good attitude toward its importance in health sciences.

Measurement of Exam Anxiety Levels Among Medical Students and Their Association With the Influencing Factors.

Introduction Studying medical science is a demanding task, often leading to exam anxiety among medical students. This study aims to measure anxiety levels among medical students and their relationship with gender, age, grades, study time, year of study, and learning methods. Methods It is a cross-sectional study involving third- to sixth-year medical students, who filled in the questionnaire related to the personal data, studying methods, and the Westside Test Anxiety Scale, to estimate the exam anxiety levels before the final examinations of the academic year 2020-2021. Completed questionnaires were reviewed, entered in Microsoft Excel, and analyzed using SPSS.  Results We found a significant association between gender and high-test anxiety (p < 0.001), with a higher prevalence among females (47.9%) compared to males (22.5%). Although non-significant, its prevalence was higher among the 20 years old (34%) and those with a GPA 4.00-4.49 (37.9%). Anxiety decreased as the students progressed to higher years of studies (37.9% in the third year to only 9.1% in sixth year, p=0.073), with the lower incidence among those who studied five days or more per week (26.7%) and no significant difference was observed whether students studying in a group or individually. Though insignificant (p=0.754), learning through textbooks was found to be less stressful (29% vs 33%). Conclusion Our findings suggest that mediocre and female students are more vulnerable to exam high-test anxiety. Progression to senior years and use of textbooks were associated with lower anxiety levels. A cohort longitudinal study to establish an association between specific factors and anxiety levels is recommended.

Longevity of Immunoglobulin-G Antibody Response Against Nucleocapsid Protein Against SARS-CoV-2 Among Healthcare Workers.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused the latest pandemic and the most significant challenge in public health worldwide. Studying the longevity of naturally developed antibodies is highly important clinically and epidemiologically. This paper assesses the longevity of antibodies developed against nucleocapsid protein amongst our health-care workers. Methods: This longitudinal cohort study was conducted at a tertiary hospital, Saudi Arabia. Anti-SARSsCoV-2 antibodies were tested among health-care workers at three-point intervals (baseline, eight weeks, and 16 weeks). Results: Of the 648 participants, 112 (17.2%) tested positive for Coronavirus (COVID-19) by PCR before the study. Of all participants, 87 (13.4%) tested positive for anti-SARS-CoV-2 antibodies, including 17 (2.6%) participants who never tested positive for COVID-19 using rt-PCR. Out of the 87 positive IgG participants at baseline, only 12 (13.7%) had remained positive for anti-SARS-CoV-2 antibodies by the end of the study. The IgG titer showed a significant reduction in values over time, where the median time for the confirmed positive rt-PCR subgroup from infection to the last positive antibody test was 70 (95% CI: 33.4-106.5) days. Conclusion: Health-care workers are at high risk of exposure to the SARS-CoV-2 virus, and contracting an asymptomatic infection is not unlikely. Developing and sustaining natural immunity differs from one person to another, while the rate of positive IgG anti-SARS-CoV-2 wanes over time.

Recurrent Urinary Tract Infection in Adult Patients, Risk Factors, and Efficacy of Low Dose Prophylactic Antibiotics Therapy.

BACKGROUND: Recurrent urinary tract infection (UTI) occurs in sizable percentages of patients after a single episode and is a frequent cause of primary healthcare visits and hospital admissions, accounting for up to one quarter of emergency department visits. We aim to describe the pattern of continuous antibiotic prophylaxis prescription for recurrent urinary tract infections, in what group of adult patients they are prescribed and their efficacy. METHODS: A retrospective chart review of all adult patients diagnosed with single and recurrent symptomatic urinary tract infection in the period of January 2016 to December 2018. RESULTS: A total of 250 patients with a single UTI episode and 227 patients with recurrent UTI episodes were included. Risk factors for recurrent UTI included diabetes mellitus, chronic renal disease, and use of immunosuppressive drugs, renal transplant, any form of urinary tract catheterization, immobilization and neurogenic bladder. E. coli infections were the most prevalent organism in patients with UTI episodes. Prophylactic antibiotics were given to 55% of patients with UTIs, Nitrofurantoin, Bactrim or amoxicillin clavulanic acid. Post renal transplant is the most frequent reason to prophylaxis antibiotics (44%). Bactrim was more prescribed in younger patients (P < 0.001), in post-renal transplantation (P < 0.001) and after urological procedures (P < 0.001), while Nitrofurantoin was more prescribed in immobilized patients (P = 0.002) and in patients with neurogenic bladder (P < 0.001). Patients who received continuous prophylactic antibiotics experienced significantly less episodes of urinary tract infections (P < 0.001), emergency room visits and hospital admissions due to urinary tract infections (P < 0.001). CONCLUSION: Despite being effective in reducing recurrent urinary tract infection rate, emergency room visits and hospital admissions due to UTI, continuous antibiotic prophylaxis was only used in 55% of patients with recurrent infections. Trimethoprim/sulfamethoxazole was the most frequently used prophylactic antibiotic. Urology and gynecological referral were infrequently requested as part of the evaluation process for patients with recurrent UTI. There was a lack of use of other interventions such as topical estrogen in postmenopausal women and documentation of education on non-pharmacological methods to decrease urinary tract infections.

Assessing the Correlation of Rate of Pathological Complete Response and Outcome in Post Neoadjuvant Chemotherapy Setting and Molecular Subtypes of Breast Cancer.

Background Neoadjuvant chemotherapy (NAC) is being widely used in treating breast cancer (BC). This study aimed to analyze the correlation between clinicopathological features, immunohistochemistry (IHC)-based molecular subtypes, and the pathological response to NAC and its relationship with disease-free survival (DFS) and overall survival (OS). Materials and methods A retrospective analysis of 211 breast cancer patients who received NAC between 2008 and 2018 was performed. Tumors were classified by IHC into luminal A, luminal B, human epidermal growth factor receptor 2 (HER2)-enriched, and triple-negative subtypes. The chi-square test was used to assess the association between pathological response and clinicopathological parameters. Cox regression analysis was used to assess factors related to DFS and OS. Results Post NAC, 19.4% of patients achieved a pathologic complete response (pCR). Estrogen receptor (ER), progesterone receptor (PR), HER2 (p<0.001, 0.005, and 0.02), Ki67 (p=0.03), molecular subtypes (p<0.001), T stage (p=0.04), and N stage (p=0.01) were significantly associated with pathological response. The rate of pCR was highest among HER2-enriched and triple-negative tumors (45.2% and 28%, respectively) with OR=0.13 and p<0.001 for the HER2-enriched subtype. Patients with pCR were 61% less likely to develop metastasis (adjusted hazard ratio [aHR]=0.39, p=0.06, 95% CI=0.14-1.06) and were significantly associated with better OS (aHR=0.07, p=0.02, 95% CI=0.01-0.61). Patients who were ≤40 years old (aHR=2.1, p=0.01), with T4 (aHR=3.4, p=0.02), grade 3 (aHR=2.5, p=0.01), and node-positive disease (HR=2.24, p=0.02) were at an increased risk of developing metastasis. High Ki67 was found to be significantly associated with better DFS (p=0.006). Conclusion HER2-enriched and triple-negative BC were associated with a higher rate of pCR. Patients with pCR had significantly better DFS and OS. Younger age, advanced stage, higher grade, and lymph node involvement were risk factors for metastasis.

Sudden unexpected death in epilepsy: What Saudi people with epilepsy want to know-A cross-sectional study.

OBJECTIVE: Sudden unexpected death in epilepsy (SUDEP) is a significant cause of mortality in people with epilepsy (PWE), with an incidence of 1 per 1000 members of the population. In Saudi Arabia, no data are available that inform local clinical practitioners about the attitudes of PWE regarding SUDEP. The aim of this study was to investigate the perspectives of Saudi PWE toward SUDEP and to assess their knowledge of SUDEP. METHODS: A cross-sectional questionnaire-based study was conducted at the neurology clinics of King Abdul-Aziz Medical City, Riyadh and Prince Sultan Military Medical City, Riyadh. RESULTS: Of the 377 patients who met the inclusion criteria, 325 completed the questionnaire. The mean age of the respondents was 32.9 ± 12.6 years. Of the study subjects, 50.5% were male. Only 41 patients (12.6%) had heard about SUDEP. Most patients (94.5%) wanted to know about SUDEP, of whom 313 (96.3%) wanted to receive this information from a neurologist. A total of 148 patients (45.5%) thought that the appropriate time to receive information about SUDEP was after the second visit, whereas only 75 (23.1%) wanted to learn about SUDEP during the first visit. However, 69 patients (21.2%) thought that the appropriate time to be informed about SUDEP was when seizure control had become more difficult. Almost half (172, 52.9%) of the patients thought that SUDEP could be prevented. SIGNIFICANCE: Our findings suggest that most Saudi PWE do not know about SUDEP and want to be counseled about their risk of SUDEP by their physicians. Therefore, education of Saudi PWE about SUDEP must be improved.

Hyperlipidemia and Hypertension Are Associated With Intracerebral Hemorrhage Incidence: A Retrospective Study.

Introduction Stroke places a huge burden on the socioeconomic systems. Hemorrhagic stroke (HS) is the second most common type of stroke and the second leading cause of disability and death. The updated data on the prevalence of intracerebral hemorrhage (ICH) stroke and related physiological risk factors in Saudi Arabia were limited. The aim of this study was to identify the prevalence of ICH stroke and the related physiological risk factors. Methods This was a retrospective, hospital-based, and chart review study that utilized the BESTCare system at King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia. Patients who attended the neurology department (inpatient/outpatient) between 2015 and 2020 were studied. The statistical tool JMP (JMP Inc., Cary, NC, USA) was used for data entry and analysis. Results Patient data (N = 1,870, 58.6 ± 13.87 years old) were screened for comorbidities, hypertension (66.1%), diabetes mellitus (DM) (57.7%), hyperlipidemia (28.4%), and history of an old stroke (22.3%). Ischemic stroke (IS) was more dominant than ICH stroke with ratios of 94.5% (n = 1767) versus 5.5% (n = 103), respectively. The prevalence of ICH stroke among the patients (n = 103) was 10.6%, 20.3%, 24.2%, and 28.1% in the age groups of <40, 41-50, 51-60, and 61-70 years old, respectively. There was a significant gender effect on the distribution of both IS and ICH (p = 0.003). ICH strokes were more prevalent in males than in females. Body mass index (BMI) has no significant effect on the prevalence of IS and ICH stroke (p = 0.081). ICH stroke was significantly associated with DM (p = 0.032), hypertension (p = 0.01), and hyperlipidemia (p = 0.002). Regression analyses show that only hypertension (positive association) and hyperlipidemia (negative association) were significantly associated with the incidence of ICH stroke. Conclusion IS was more prevalent than ICH stroke. ICH strokes were more prevalent in males than in females. Also, hypertension was the most common factor leading to ICH stroke, unlike hyperlipidemia, which was revealed to be protective against ICH stroke.

Increased Prevalence of EBV Infection in Nasopharyngeal Carcinoma Patients: A Six-Year Cross-Sectional Study.

Epstein Barr Virus (EBV) is implicated in the carcinogenesis of nasopharyngeal carcinoma (NPC) and currently associated with at least 1% of global cancers. The differential prognosis analysis of NPC in EBV genotypes remains to be elucidated. Medical, radiological, pathological, and laboratory reports of 146 NPC patients were collected retrospectively over a 6-year period between 2015 and 2020. From the pathology archives, DNA was extracted from tumor blocks and used for EBV nuclear antigen 3C (EBNA-3C) genotyping by nested polymerase chain reaction (PCR). We found a high prevalence of 96% of EBV infection in NPC patients with a predominance of genotype I detected in 73% of NPC samples. Histopathological examination showed that most of the NPC patients were in the advanced stages of cancer: stage III (38.4%) or stage IV-B (37.7%). Only keratinized squamous cell carcinoma was significantly higher in EBV negative NPC patients compared with those who were EBV positive (OR = 0.01, 95%CI = (0.004-0.32; p = 0.009)), whereas the majority of patients (91.8%) had undifferentiated, non-keratinizing squamous cell carcinoma, followed by differentiated, non-keratinizing squamous cell carcinoma (7.5%). Although NPC had metastasized to 16% of other body sites, it was not associated with EBV infection, except for lung metastasis. A statistically significant reverse association was observed between EBV infection and lung metastasis (OR = 0.07, 95%CI = (0.01-0.51; p = 0.008)). Although 13% of NPC patients died, the overall survival (OS) mean time was 5.59 years. Given the high prevalence of EBV-associated NPC in our population, Saudi could be considered as an area with a high incidence of EBV-associated NPC with a predominance of EBV genotype I. A future multi-center study with a larger sample size is needed to assess the true burden of EBV-associated NPC in Saudi Arabia.

Consequences of neglected traumatic spinal cord injuries.

Objectives: Spinal cord injuries cause major disabilities and are devastating events for both patients and healthcare providers. Most traumatic spinal cord injuries (TSCIs) are due to motor vehicle accidents (MVAs). Neglected injuries result in complications and poor outcomes. Here, we investigated the causes, consequences, and outcomes of neglected TSCIs. Methods: This case series study was performed at King Abdulaziz Medical City, Riyadh, KSA. Of the 750 patients treated between February 2016 and February 2021, 18 patients met our inclusion criterion of neglected high-energy TSCI with neurological deficit, necessitating surgical intervention more than 14 days after the index trauma. Results: Of the 18 patients with neglected TSCIs, 72.2% were men. The patients' mean age at the time of injury was 36.8 years, 77.8% were from outside Riyadh, and all patients had MVA-induced TSCIs, 88.9% of which were attributable to delayed referral to a tertiary center. The mean duration of neglect was 43 days, and the longest duration was 125 days. The most common site of injury was the thoracolumbar region (55.5%). The American Spinal Injury Association impairment scale score improved in two patients. Bed sores occurred in 55.5%, and deep vein thrombosis occurred in 27.8% of patients. Postoperatively, 77% of patients required intensive care unit admission. Most patients (12) did not receive specialized spinal cord injury rehabilitation postoperatively. Conclusion: Early referral of patients with TSCIs is crucial to prevent short- and long-term complications.
