Real-life experiences and barriers to adjuvant chemotherapy in Saudi patients with advanced stage II and stage III colon cancer.

BACKGROUND: Colorectal cancer is the most common malignancy in Saudi males and third most common in females. Patients with locally advanced colon cancer may eventually develop metastatic disease if not treated promptly and according to guidelines. The recent National Comprehensive Cancer Network guideline recommends tumor resection followed by adjuvant chemotherapy for stage III and high-risk stage II tumors. Therefore, the objective of this study was to characterize patients with locally advanced colon cancer and identify factors associated with the use of adjuvant chemotherapy and the addition of oxaliplatin in locally advanced colon cancer patients. METHODS: All patients diagnosed with locally advanced colon cancer at National Guard Health Affairs (NGHA) during 2016-2021 were investigated. Patients' characteristics were compared using Chi-square and Fisher exact test, whereas predictors of adjuvant chemotherapy/Oxaliplatin use were identified using univariate and multivariate logistic regression. RESULTS: Out of 222 patients diagnosed with locally advanced colon cancer, 133 received adjuvant chemotherapy. Factors associated with adjuvant chemotherapy administration were age and smoking status. In the multivariable analysis, older patients were less likely to receive oxaliplatin than younger patients. Stage III patients diagnosed during 2019-2021 had 5.61 times higher odds of receiving oxaliplatin. CONCLUSION: The findings of this study show that older patients and smokers are less likely to be treated with adjuvant chemotherapy. Moreover, age as well as diagnosis year were important determinants of oxaliplatin administration in stage III locally advanced colon cancer patients.

Factors associated with 30-day mortality and morbidity in patients undergoing emergency colorectal surgery.

BACKGROUND: The 30-day period following emergency colorectal surgery (ECRS) is associated with high mortality and morbidity. There is a lack of data assessing factors associated with outcomes of ECRS in the Saudi population. OBJECTIVES: Assess factors associated with 30-day postoperative mortality and complications following ECRS. DESIGN: Retrospective cohort study. SETTING: Single tertiary care center, Riyadh, Saudi Arabia. PATIENTS AND METHODS: Demographic characteristics (age, sex, diagnosis, American Society of Anesthesiologists classification, pre-operative septic state, smoking, and comorbidities), operative characteristics (urgency, diverting ostomy, and procedure performed), and postoperative characteristics (length of stay, 30-day mortality, intensive care unit [ICU] admission, ICU length of stay, surgical site infection [SSI], readmission, reoperation, and complications) were collected from electronic medical records. Univariate logistic regression was used to evaluate association with the outcome measures (30-day mortality and postoperative complications). Multivariate logistic regression was applied to evaluate independent variables. MAIN OUTCOME MEASURE: Thirty-day postoperative mortality and morbidity. SAMPLE SIZE: 241 patients. RESULTS: Among 241 patients, 145 (60.2%) were men, and 80 (33.2%) patients were between 50-64 years of age. The most common indication for surgery was malignancy 138 (57%). The overall complication rate was 26.6% and the 30-day mortality rate was 11.2%. Left hemicolectomy was the most commonly performed procedure, performed in 69 (28.6%) patients. Patients between the age of 65-74 had an increased odds of death within 30 days (OR 5.25 [95% CI 1.03-26.5]) on univariate analysis. Preoperative sepsis was associated with a fourfold increase in the likelihood of 30-day mortality (OR 4.44, 95% CI 1.21-16.24, P=.024) on multivariate analysis. The likelihood of hospital re-admission increased by fivefold in patients who developed a postoperative complication (OR 5.33, 95% CI 1.30-21.78, P=.02). CONCLUSION: Preoperative sepsis was independently associated with 30-day mortality in patients undergoing ECRS, while the likelihood of hospital readmission increased in patients with postoperative complications. Expeditious control of sepsis in the emergency surgical setting by both surgical and medical interventions may reduce the likelihood of postoperative mortality. Establishing discharge protocols for postoperative ECRS patients is advocated. LIMITATIONS: Retrospective design, small sample size, and single setting.

Pharmacogenes that demonstrate high association evidence according to CPIC, DPWG, and PharmGKB.

Background: Different levels of evidence related to the variable responses of individuals to drug treatment have been reported in various pharmacogenomic (PGx) databases. Identification of gene-drug pairs with strong association evidence can be helpful in prioritizing the implementation of PGx guidelines and focusing on a gene panel. This study aimed to determine the pharmacogenes with the highest evidence-based association and to indicate their involvement in drug-gene interactions. Methodology: The publicly available datasets CPIC, DPWG, and PharmGKB were selected to determine the pharmacogenes with the highest drug outcome associations. The upper two levels of evidence rated by the three scoring methods were specified (levels A-B in CPIC, 3-4 in DPWG, or 1-2 levels in PharmGKB). The identified pharmacogenes were further ranked in this study based on the number of medications they interacted with. Results: Fifty pharmacogenes, with high to moderately high evidence of associations with drug response alterations, with potential influence on the therapeutic and/or toxicity outcomes of 152 drugs were identified. CYP2D6, CYP2C9, CYP2C19, G6PD, HLA-B, SLCO1B1, CACNA1S, RYR1, MT-RNR1, and IFNL4 are the top 10 pharmacogenes, where each is predicted to impact patients' responses to ≥5 drugs. Conclusion: This study identified the most important pharmacogenes based on the highest-ranked association evidence and their frequency of involvement in affecting multiple drugs. The obtained data is useful for customizing a gene panel for PGx testing. Identifying the strength of scientific evidence supporting drug-gene interactions aids drug prescribers in making the best clinical decision.

The 30-day hospital readmission and mortality after surgery in colorectal cancer patients.

PURPOSE: Hospital readmissions in the first weeks following surgery are common, expensive, and associated with increased mortality among colorectal cancer patients. This study is designed to assess the 30-day hospital readmission after colorectal cancer surgery and evaluate the risk factors that affect hospital readmission. METHODS: The study uses data from the Ministry of National Guard-Health Affairs Cancer Registry. All colorectal cancer patients who underwent colorectal cancer surgery between January 1, 2016, and November 31, 2021, were investigated. Factors examined were age, gender, marital status, Body Mass Index, Charlson Comorbidity Index, chemotherapy, radiotherapy, tumor stage, grade, site, surgical approach, length of stay, and discharge location. Kaplan-Meier curves were constructed to assess survival rates between readmitted and non-readmitted patients, and logistic regressions were performed to assess predictors of readmission. RESULTS: A total of 356 patients underwent tumor resection and 49 patients were readmitted within 30-day of index discharge. The most common reasons for hospital readmissions were gastrointestinal (22.45%), urinary tract infection (16.33%), and surgical site infection (12.24%). In the multivariable analysis, females were 89% more likely to be readmitted compared to males (odds ratio 1.89, 95% confidence intervals 1.00-3.58). Patients with distant metastatic tumors have higher odds of readmission (odds ratio 4.52, 95% confidence intervals 1.39-14.71) compared to patients with localized disease. CONCLUSIONS: Colorectal cancer readmission is more common in patients with metastatic disease. Strategies to reduce readmission include planned transition to outpatient care, especially among patients with a high risk of readmission.

Primary tumor location and survival among metastatic colorectal cancer patients treated with systemic chemotherapy and biologic therapies: Retrospective analysis.

BACKGROUND: Metastatic colorectal cancer (mCRC) is a genetically heterogeneous disease and different ethnicities might result in different chemotherapy treatment responses. The aim of the study is to evaluate whether survival outcomes for mCRC patients treated with systemic chemotherapy (SC) and, with and without biologic therapies (BT) are different between left and right-sided tumors. METHODS: A retrospective cohort study via the Ministry of National Guard- Health Affairs (MNG-HA) Cancer registry data was used to identify patients diagnosed with CRC between 2013 and 2016. Kaplan-Meier method and porosity score Cox proportional hazard models were used to assess survival for right and left-sided mCRC with and with BT. RESULTS: There was a total of 549 CRC patients and 196 mCRC patients with mean age of 64 years and 57.65% were males. The median survival for the left-sided was higher than the right-sided mCRC tumors (P 0.03). mCRC patients treated with SC+BT were associated with decreased mortality only among patients with left-sided mCRC compared to right-sided mCRC (HR, 0.21; 95% CI, 0.05-0.92; P 0.03). mCRC with no primary-tumor resection and CS+TB left-sided mCRC was significantly associated with decreased mortality compared to right-sided mCRC (HR, 0.15; 95% CI, 0.03-0.72; P 0.02). CONCLUSION: A significant decrease in mortality for the left-sided mCRC treated with SC + BT compared with the right-sided mCRC was observed. mCRC patients with unresectable metastases demonstrated survival benefits from left-sided SC + BT treatment. Randomized controlled trials are needed to determine the optimal treatment for mCRC patients.

Prevalence of exposure to pharmacogenetic drugs by the Saudis treated at the health care centers of the Ministry of National Guard.

Background: The drugs impacted by genetic variants are known as pharmacogenetic (PGx) drugs. Patients' responses to these drugs may vary according to the variability in patients' genetic makeup. Hence, exploring the pharmacogenes that affect drug treatment is vital to ensure optimal therapy and patients' safety. This study aimed to describe the usage rate of PGx drugs and the frequency of relevant variants in the Saudi population. Methodology: Prescription patterns over seven years (2015-2021) for Saudi patients on PGx drugs treated at the Ministry of National Guard-Health Affairs (MNG-HA) were investigated. Only registered drugs in the MNG-HA formulary (n = 78) were included. The patients were subgrouped into four age groups: ≤24, 25-44, 45-64, and ≥65 years. Further subgrouping was made according to gender and drugs' therapeutic categories following anatomical therapeutic chemical (ATC) classification.Furthermore, an online searching was carried out to identify the pharmacogenes reported in the literature among healthy Saudis. The search included 45 genes that may affect drug outcomes based on evidence rated by either CPIC (A-B levels) or PharmGKB (1-2 levels). Results: The screened patients were 1,483,905. Patients on PGx drugs accounted for 46.7% (n = 693,077 patients). The analgesic group was the most prescribed drug category (47%), which included ibuprofen (20.5%), celecoxib (6.3%), tramadol (5.8%), and others. Cardiovascular agents were the second-most utilized drug class (24.4%). Omeprazole was the second most commonly used medication (11.1%) but ranked third as a class (gastroenterology). Females used PGx drugs more frequently than males (53.5% versus 46.5%) and a higher usage rate by patients aged 45-64 years (31.3%) was noted. The cytochrome P450 genes (CYP2C9, CYP2C19, and CYP2D6) were estimated to impact responses of 54.3% (n = 1,156,113) of the used drugs (27.2% are possibly affected by CYP2C9, 12.8% by CYP2C19, and 14.3% by CYP2D6). Thirty-five pharmacogenes that characterize Saudi population and their variants' allele frequencies were identified from previous reports. This study presents the largest reported number of genes that may affect drug therapies among Saudis. Conclusion: This study confirmed that a high percentage of Saudi patients use PGx drugs and various genotypes of certain pharmacogenes are inherited by the Saudi population.

Comparison of Hospital Readmission and Mortality between COVID-19 and Pneumonia Patients.

Coronavirus disease 2019 (COVID-19) survivors can have lasting signs and symptoms, including various organ damage, indicating that COVID-19 can be a chronic illness. The current study aims to compare the 30-day hospital readmission and death rate of patients admitted to the hospital with COVID-19 and pneumonia due to other causes. A retrospective cohort study was conducted using data from the Saudi National Guard Health Affairs (NGHA). Records of patients admitted with COVID-19 between 1 March 202 and 31 December 2020 (n = 3597) and pneumonia during 2017 and 2019 (n = 6324) were retrieved and analyzed. We compared the likelihood of 30-day hospital readmission, intensive care unit (ICU) admission, and death between the two groups. Compared with the control group, COVID-19 patients had higher odds of 30-day readmission (odds ratio 1.90, 95% confidence interval 1.61-2.24), higher risk of ICU transfer (hazard ratio 1.85, 95% confidence interval 1.65-2.07), more extended hospital stay (7 vs. 4 days), but less risk of death (hazard ratio 0.18, 95% confidence interval 0.14-0.24). The findings that hospital readmission was higher in COVID-19 recovered patients than in other pneumonia patients inform the current discussion about readmission and death in COVID-19 patients.

The Relationship Between e-Health Literacy and Breast Cancer Literacy Among Saudi Women.

Breast cancer is the most common cancer in women and represents a significant burden among women worldwide. The concept of health literacy is relatively new to the Gulf states, particularly to Saudi Arabia. Research on this topic is scarce, and no study has empirically explored the influence of e-health literacy on breast cancer literacy. The purpose of this study was to measure the impact of e-health literacy on breast cancer literacy among Saudi women in Riyadh city, Saudi Arabia. A cross-sectional survey was conducted online in a cohort of 336 women and disseminated via social media using the e-Health Literacy Scale (eHEALS) and Breast Cancer Literacy Assessment Tool (Breast-CLAT). Multiple regression analysis was executed to identify the sociodemographic factors that influence the e-health literacy and breast cancer literacy of participants. The participants showed high level of e-health literacy with total eHEALS score of 28.79, and better breast cancer literacy with total Breast-CLAT score of 23.44. This study yielded three significant findings: (1) e-health literacy is influenced by age and education which implies that youngest participants showed higher eHEALS scores than their older counterparts and that having increased education level reflected increased eHEALS scores, (2) breast cancer literacy is predicted by education and income which suggests that those who have higher levels of education and higher monthly incomes have increased levels of breast cancer literacy, and (3) breast cancer literacy and e-health literacy were associated which shows that participants with higher eHEALS scores were more likely have increased level of breast cancer literacy. The study revealed that the participants had high level of e-health literacy which correlated to their increased level of breast cancer literacy. The study findings implied that it is important for Saudi women to possess high levels of e-health literacy about breast cancer as more breast cancer educational resources are online nowadays.

Trends in Colorectal Cancer Incidence Rates in Saudi Arabia (2001-2016) Using Saudi National Registry: Early- Versus Late-Onset Disease.

Early-onset (<50 years old) colorectal cancer (CRC) has been increasing worldwide and is associated with poor outcomes. Over 85% of the Saudi population are <50 years old, which put them at heightened risk of early-onset CRC. No study assessed the trends in CRC incidence rates among the Saudis. The Joinpoint Regression software by the Surveillance, Epidemiology, and End Results (SEER) program was used to estimate the magnitude and direction of CRC incidence trends by age and gender. The annual percentage change (APC) and the average annual percentage change (AAPC) between 2001 and 2016 were computed. In a sensitivity analysis, we also assessed trends using various age groups. Between 2001 and 2016, the early-onset CRC incidence (per 105) increased from 1.32 (95% CI: 1.11, 1.54) to 2.02 (95% CI: 1.83, 2.22) with AAPC (2.6, 95% CI: -0.4, 5.7). At same period, the late-onset incidence increased from 3.54 (95% CI: 3.10, 3.97) to 9.14 (95% CI: 8.62, 9.66) with AAPC (6.1, 95% CI: 3.5, 8.8). Among early-onset CRC patients, age 40-49 has the highest rates and women in this age group has higher rate than men. Our national data showed a gradual increase in CRC incidence rates, which reflect the global concern of early-onset CRC. Further research is needed to understand the etiology of early-onset CRC. Primary health care providers must be alerted about the increasing rate of early-onset CRC. To reduce the future burden of the disease, initiating CRC screening before age 50 is warranted.

Colorectal cancer survival among Ministry of National Guard-Health Affairs (MNG-HA) population 2009-2017: retrospective study.

BACKGROUND: Colorectal cancer (CRC) is the most diagnosed cancer among males and third among females in Saudi Arabia, with up to two-third diagnosed at advanced stage. The objective of our study was to estimate CRC survival and determine prognostic factors. METHODS: Ministry of National Guard- Health Affairs (MNG-HA) registry data was utilized to identify patients diagnosed with CRC between 2009 and 2017. Cases were followed until December 30th, 2017 to assess their one-, three-, and five-year CRC-specific survivals. Kaplan-Meier method and Cox proportional hazard models were used to assess survival from CRC. RESULTS: A total of 1012 CRC patients were diagnosed during 2009-2017. Nearly, one-fourth of the patients presented with rectal tumor, 42.89% with left colon and 33.41% of the cases were diagnosed at distant metastasis stage. The overall one-, three-, and five-year survival were 83, 65 and 52.0%, respectively. The five-year survival was 79.85% for localized stage, 63.25% for regional stage and 20.31% for distant metastasis. Multivariate analyses showed that age, diagnosis period, stage, nationality, basis of diagnosis, morphology and location of tumor were associated with survival. CONCLUSIONS: Findings reveal poor survival compared to Surveillance, Epidemiology, and End Results (SEER) population. Diagnoses at late stage and no surgical and/or perioperative chemotherapy were associated with increased risk of death. Population-based screening in this population should be considered.

Comparison of Urban-Rural Readmission Rates After Colorectal Cancer Surgery: Findings From a Privately Insured Population.

OBJECTIVES: We assessed the 30-day readmission rate of a privately insured population diagnosed with colorectal cancer (CRC) who had primary tumor resection in rural and urban communities. METHODS: Claims data of people aged <65 with a diagnosis of CRC between 2012 and 2016 and enrolled in a private health plan administered by BlueCross BlueShield of Nebraska were analyzed. Readmission was defined as the number of discharged patients who were readmitted within 30 days, divided by all discharged patients. Multivariate logistic regression was used to estimate the factors associated with readmission. RESULTS: The urban population had a higher readmission rate (11%) than the rural population (8%). Although the adjusted odds ratio showed that there is no difference in readmission between rural and urban residents, patients with a Charlson Comorbidity Index (CCI) of >1 were more likely than those without CCI to be readmitted (OR 3.59, 1.41-9.11). Patients with open vs. laparoscopic surgery (OR 2.80, 1.39-5.63) and those with an obstructed or perforated colon vs. none (OR 7.17, 3.75-13.72) were more likely to be readmitted. CONCLUSIONS: Readmission after CRC surgery occurs frequently. Interventions that target the identified risk factors should reduce readmission rates in this privately insured population.

Medical students' awareness of Personal Digital Assistant Devices' impact on their health.

AIMS: 1. To evaluate medical students' awareness of personal digital assistant devices impacts on their overall health. 2. To estimate medical students' hours on digital devices. 3. To determine the most common effect of personal digital assistant devices on medical student health. SETTINGS AND METHOD: This descriptive cross-sectional study was conducted at the college of medicine of a in Riyadh, Saudi Arabia. The participants were medical students, and a questionnaire consists of 3 sections was used. A sample of 289 medical students participated in the study. Kruskal-Wallis test was used to analyze the relationship between the knowledge score and the year of study. STATISTICAL ANALYSIS USED AND RESULTS: The research included medical students whose ages ranged from 19 to 25 years with a median (IQR) of 22.00 (21.00-23.00). Approximately, 56% of the participants were males, and the majority of the students were from year 3. The average hours spent daily while using PDA for studying was 5 hours with SD 2.7. 167 (58%) of the students reported that studying using PDAs has affected their life. The most experienced effects reported was dry eyes and vision problems 53 (54%). CONCLUSIONS: The current study revealed that the majority of medical students have adequate knowledge of PDAs' effects on their health despite their continuous use. More attention should be paid to reduce the effects on their health by raising campaigns to increase the awareness of all the students and the community.

The effect of marital status on stage at diagnosis and survival in Saudis diagnosed with colorectal cancer: cancer registry analysis.

Colorectal cancer (CRC) is the most common cancer in males and third in females in Saudi Arabia, with the majority (66%) diagnosed at a late stage. We evaluated the effect of marital status on stage at diagnosis and CRC survival. We hypothesized that married patients would be more likely to present at an early stage and have higher survival than unmarried patients. The Ministry of National Guard-Health Affairs (MNG-HA) cancer registry was used to identify patients diagnosed with CRC from 2009 to 2017. A competing risk analysis was performed to assess the 5-year CRC-specific survival, adjusting for potential confounders. The Kaplan-Meier method and the Cox regressions were used to assess survival. Two-thirds (76.50%) of the 936 CRC patients were married, 11.64% were unmarried, and 11.86% had an unknown marital status. With multiple imputation-based analysis, the multivariate analysis indicated that unmarried patients were 52% more likely to present at an advanced stage [adjusted odds ratio (aOR) 1.52; 95% CI 1.33-1.73], and had a 30% higher risk of death due to CRC compared to the married patients (aHR 1.30; CI 1.17, 1.44). Future CRC screening and survivorship programs should assess the needs of the vulnerable unmarried population. Interventions supporting the early detection of CRC in this population may be beneficial in the long term and lead to improved cancer outcomes.

Colorectal Cancer Screening Uptake: Differences Between Rural and Urban Privately-Insured Population.

Earlier studies investigated rural-urban colorectal cancer (CRC) screening disparities among older adults or used surveys. The objective was to compare screening uptake between rural and urban individuals 50-64 years of age using private health insurance. Data were analyzed from 58,774 Blue Cross Blue Shield of Nebraska beneficiaries. Logistic regression was used to assess the association between rural-urban and CRC screening use. Results indicate that rural individuals were 56% more likely to use the Fecal Occult Blood Test (FOBT) compared with urban residents, but rural females were 68% less likely to use FOBT. Individuals with few Primary Care Physician (PCP) visits and rural-women are the least to receive screening. To enhance CRC screening, a policy should be devised for the training and placement of female PCP in rural areas. In particular, multilevel interventions, including education, more resources, and policies to increase uptake of colorectal cancer screening, are needed. Further research is warranted to investigate barriers to CRC screening in rural areas.

The Outcome of Unscreened Population in Colorectal Cancer: The Impact of Sex and Other Determinants on Cancer Stage.

BACKGROUND: In Saudi Arabia, there is no population-based colorectal cancer (CRC) screening, and more than two-thirds of patients are diagnosed with a late stage. We assessed the association between sex and distant metastasis CRC and hypothesize that females, younger age, non-married, and patients with colon cancer would present with metastatic tumors. PATIENTS AND METHODS: The retrospective cohort study used data from the Ministry of National Guard Cancer Registry. Logistic regression was used to assess the association between sex and metastatic CRC adjusting for patient covariates. In a sensitivity analysis, the association between sex and late-stage CRC was evaluated. RESULTS: A total of 1016 CRC patients met the eligibility criteria, with 37.59% of females and 30.26% of males diagnosed with metastatic CRC. After adjusting for marital status, grade, and morphology, females were 20% more likely than males to present with a metastatic tumor 1.20 (95% CI, 1.04-1.38). CONCLUSION: Although the entire Saudi population would benefit from CRC screening, women may benefit the most from targeted screening.

Predictors of Seatbelt Use Among Saudi Adults: Results From the National Biobank Project.

Introduction: Road traffic crashes (RTCs) are a leading cause of death and disabilities and impose a significant burden on the healthcare system and economy of Saudi Arabia. Around 20% of all hospital beds are occupied by victims of RTCs, which represent approximately 80% of trauma deaths occurring in these facilities. Using a seatbelt is an effective method to reduce traffic deaths and minimize the extent of associated injuries. However, little is currently known about the prevalence and predictors of seatbelt use in Saudi Arabia. More studies are needed to determine the trends of seatbelt use and study the relationship between individual factors and compliance with seatbelt use laws. The aim of the present study is to examine the prevalence and predictors of seatbelt use using the National Saudi Biobank dataset. Materials and Methods: This cross-sectional study was conducted using an in-person survey from the Saudi National Biobank (SNB). The participants were adults affiliated with the Ministry of National Guard Health Affairs in Riyadh who were examined between 2017 and 2019. Chi-squared and Wald tests were used to assess the association between the respondents' characteristics and their seatbelt use. In addition, logistic regression models were constructed to assess the univariate and multivariate associations between seatbelt use and potential predictors. All statistical tests were two-sided, and the findings were considered significant at P < 0.05. Results: A total of 5,790 adults participated in the survey. The majority of the participants (52.44%) were between 18 and 25 years old, half were males, and 58.80% were single. About 42.83% of the participants reported consistent seatbelt use as drivers or passengers. In the multivariable analysis, females were 86% less likely to wear seatbelts than males (OR = 0.136, 95%CI = 0.107-0.173). Individuals who rated their mental health as "weak" were 26% less likely to wear seatbelts than those who reported "excellent" mental health status. Conclusion: Seatbelt use remains low in the country and substantially lower than in developed countries. Young adults, females, and individuals reporting suboptimal mental health were less likely to fasten their seatbelts. These findings are valuable for public health programs to target specific groups and raise awareness about the need to increase seatbelt compliance and reduce traffic injuries.

Risk Assessment of Repeated Suicide Attempts Among Youth in Saudi Arabia.

INTRODUCTION: Although the incidence of suicide attempts continues to increase among youth in Saudi Arabia, no risk assessment tool has been established for suicide attempt repetition in the country's youth population. The objective of the study was to develop risk assessment of suicide attempt repetition among youth in Saudi Arabia. METHODS: This is a retrospective study of youth (10-24 years) with intentional suicide attempt(s) who presented to the emergency departments (ED) at King Abdullah Specialist Children's Hospital (KASCH) and King Abdulaziz Medical City-Riyadh (KAMC-R), Saudi Arabia between 1 January 2015 and 31 December 2017. We excluded youth having unintentional suicide attempts. Data were retrieved for the 157 eligible as having attempted suicide. RESULTS: Forty-one of 157 (26.1%) had repeated suicide attempts (95% confidence limits: 19.433.7%). Four independent factors were identified that were associated with an increased risk of repeated suicide attempts: age (adjusted odds ratio [aOR] = 1.147, 95% confidence interval (CI) = 11.015-1.297, P=0.028), family problems (aOR = 4.218, 95% CI = 1.690-10.528, P=0.002), psychiatric disorders (aOR = 3.497, 95% CI = 1.519-8.051, P=0.003), and hospitalization (aOR = 5.143, 95% CI = 1.421-18.610, P=0.013). This risk model showed adequate utility with an area under the receiver operating characteristic (ROC) curve (AUC): 77.9%, 95% CI: 69.486.3% with optimism-corrected AUC = 71.8%. Youden index defined a probability of ≥0.38 to predict a high risk of repeated suicide attempts. CONCLUSION: The risk of repeated suicide attempts among Saudi youth was high, compatible with what has been reported among youth in England and in France. Age, family problems, psychiatric disorders, and hospitalization are risk factors for repeated suicide attempts. A prevention program for suicide attempts in youth may take into account family problems, screening for psychiatric disorders, and suicidal behavior.

Prevalence and Clinical Characteristics of Alopecia Areata at a Tertiary Care Center in Saudi Arabia.

RESULTS: A total of 216 patients with AA were included. The overall prevalence of AA was approximately 2.3%. The mean disease duration at the time of presentation was 2 months while the mean age of onset was 25.61 years. The most common type of AA in both adult and pediatric groups was the patchy type involving the scalp. Comorbid diseases were found in 32.41% of patients. Common associated conditions included hypothyroidism, diabetes mellitus, and atopic diseases. CONCLUSION: The overall prevalence of AA among a population of Saudi patients is 2.3%. AA prevalence is higher in pediatrics than adults. Common comorbid conditions include hypothyroidism, diabetes mellitus, and atopic diseases.

Colorectal cancer in Saudi Arabia as the proof-of-principle model for implementing strategies of predictive, preventive, and personalized medicine in healthcare.

Colorectal cancer (CRC) is the most commonly diagnosed cancer among Saudi males and ranks third in females with up to 73% of cases diagnosed at late stage. This review provides an analysis of CRC situation in the Kingdom of Saudi Arabia (KSA) from healthcare perspective. A PUBMED (1986-2018) search was done to identify publications focusing on CRC in KSA. Due to reports of increased CRC incidence among young age group (< 50), and given the young population of KSA, the disease may burden the national healthcare system in the next decades. Environmental factors attributed to increasing incidence rates of CRC include red meat consumption, sedentary lifestyle, and increased calorie intake. Despite substantial investment in healthcare, attention to predictive diagnostics and targeted prevention is lacking. There is a need to develop national screening guidelines based on evidence that supports a reduction in incidence and mortality of CRC when screening is implemented. Future approaches are discussed based on multi-level diagnostics, risk assessment, and population screening programs focused on the needs of young populations that among others present the contents of the advanced approach by predictive, preventive, and personalized medicine. Recommendations are provided that could help to develop policies at regional and national levels. Countries with demographics and lifestyle similar to KSA may gain insights from this review to shape their policies and procedures.

Impact of the 2017 ACC/AHA guideline on the prevalence of elevated blood pressure and hypertension: a cross-sectional analysis of 10 799 individuals.

OBJECTIVES: To assess the effect of the 2017 American College of Cardiology and the American Heart Association (ACC/AHA) hypertension guideline on the prevalence of elevated blood pressure (BP) and hypertension and the initiation of antihypertensive treatment, as well as the level of adherence to the BP target in the Saudi population. DESIGN: A cross-sectional study. PARTICIPANTS: A total of 10 799 adults (≥18 years old), with three BP readings during 2017-2020 from the Saudi Biobank was used. PRIMARY OUTCOME: Hypertension was defined using three sources: the Joint National Committee 7 Blood Pressure Guideline (JNC-7) guideline (systolic BP (SBP)≥140 or diastolic BP (DBP)≥90 mm Hg), the 2017 ACC/AHA guideline (SBP≥130 or DBP≥80 mm Hg) and a self-reported hypertension diagnosis. RESULTS: The prevalence of hypertension, according to the JNC-7 guideline, was 14.49% (95% CI 14.37 to 14.61), and the 2017 ACC/AHA, 40.77% (95% CI 40.60 to 40.94), a difference of 26.28%. Antihypertensive medication was recommended for 24.84% (95% CI 24.69 to 24.98) based on the JNC-7 guideline and 27.67% (95% CI 27.52 to 27.82) using the 2017 ACC/AHA guideline. Lifestyle modification was recommended for 13.10% (95% CI 12.47 to 13.74) of patients with hypertension who were not eligible for a pharmacological intervention, based on the 2017 ACA/AHA guideline. For patients with prescribed antihypertensive medication, 49.56% (95% CI 45.50 to 53.64) and 27.81% (95% CI 24.31 to 31.59) presented with a BP reading above the treatment goal, based on the 2017 ACA/AHA and JNC-7 guidelines, respectively. Using the two definitions, the risk factors were older age, male gender, diabetes diagnosis, increased body mass index, waist circumference and waist-to-hip ratio. CONCLUSIONS: According to the 2017 ACC/AHA guideline, the prevalence of hypertension has increased significantly, but there was only a small increase in the proportion of patients recommended for antihypertensive treatment. A large proportion of patients with prescribed antihypertensive medication, had a BP above the target. Unless public health prevention efforts are adopted, the increased prevalence of elevated BP and hypertension will increase cardiovascular disease.
