Validation of the Arabic version of the Epworth Sleepiness Scale

Background: The Epworth Sleepiness Scale (ESS) is a questionnaire widely used in developed countries to measure daytime sleepiness and diagnose sleep disorders. Objective: This study aimed to develop an ESS questionnaire for the Arabic population (ArESS), to determine ArESS internal consistency, and to measure ArESS test–retest reproducibility. It also investigated whether the normal range of ESS scores of healthy people in different cultures are similar. Methods: The original ESS questionnaire was translated from English to Arabic and back-translated to English. In both the English and Arabic translations of the survey, ESS consists of eight different situations. The subject was asked to rate the chance of dozing in each situation on a scale of 0–3 with total scores ranging between 0 (normal sleep) and 24 (very sleepy). An Arabic translation of the ESS questionnaire was administered to 90 healthy subjects. Results: Item analysis revealed high internal consistency within ArESS questionnaire (Cronbach’s alpha = 0.86 in the initial test, and 0.89 in the retest). The test–retest intra-class correlation coefficient (ICC) shows that the test–retest reliability was substantially high: ICC = 0.86 (95% confidence interval: 0.789–0.909, p-value < 0.001). The difference in ArESS scores between the initial test and retest was not significantly different from zero (average difference = −0.19, t = −0.51, df = 89, p-value = 0.611). In this study, the averages of the ESS scores (6.3 ± 4.7, range 0–20 in the initial test and 6.5 ± 5.3, range 0–20 in the retest) are considered high in Western cultures. Conclusions: The study shows that the ArESS is a valid and reliable tool that can be used in Arabic-speaking populations to measure daytime sleepiness. The current study has shown that the average ESS score of healthy Arabian subjects is significantly higher than in Western cultures.

The predictors of poor quality of life in a sample of Saudi women with breast cancer

Background The protocols for treatment, along with many adverse effects, can strongly affect cancer patients’ quality of life (QoL). As there is limited research on the QoL of Saudi Arabian women being treated for breast cancer, the purpose of this study was to identify the predictors of poor QoL in a sample of Saudi women with breast cancer. Methods A cross-sectional study was conducted on 145 Saudi women with breast cancer who attended the Oncology Outpatient Clinic at King Abdulaziz Medical City, Riyadh for routine follow-up. Sociodemographic and clinical data were collected for each patient, and a Medical Outcome Study Health Survey 36-Item Short Form (SF-36) instrument was used to assess QoL. Results Of 145 breast cancer patients studied, 42.1% had a family history of cancer and 52.4% were newly diagnosed cancer patients (first-year-after-cancer diagnosis). According to linear regression analyses, cancer patients with metastasis tended to have pain, along with poor physical function, little vitality, and poor general health (a decrease in SF-36 scores of 22.9, 15.0, 19.4, and 16.9, respectively). Regular exercise was a positive predictor of poor general health (an increase in the SF-36 score of 8.2). Patients with first-year-after-cancer diagnoses tended to have poor emotional well-being (a decrease in the SF-36 score of 8.5). Conclusion In breast cancer patients, regular exercise was a significant positive predictor of better general health. Breast cancer patients with multiple tumors, metastasis, or fever tended to experience significantly poor QoL in several SF-36 domains. Clearly, a routine assessment of QoL in breast cancer patients is important.

Factors associated with poor asthma control among asthmatic patient visiting emergency department

Bronchial asthma is a common chronic disease that affects people of all ages. Insufficient asthma control may cause frequent emergency department (ED) visit by patients who seek crisis management of their asthma.

Prevalence of sleep duration among Saudi adults

Objectives: To examine the associations between sleep duration and a variety of demographic and clinical variables in a sample of Saudi adults. Methods: A cross-sectional study among 2,095 participants was conducted at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia, between May and October 2014. A questionnaire was administered to collect data related to clinical health outcomes and demographic characteristics. Participants were asked to report their average sleep duration per night in hours. Results: One-third (33.8%) reported short sleep duration of less than 7 hours/night. Short sleep duration was more prevalent in females (37.3% versus 31.4%, p=0.004). The most common medical problems reported were obesity with body mass index of >30 Kg/m2 (39.1%), hypertension (33.9%), diabetes mellitus (20.8%), depression (4.3%), asthma (17.3%), COPD (6.6%), and hyperlipidemia (2.7%). Diabetes mellitus was associated with long sleep of more than 9 hours/night (25.4%, p=0.011) and hypertension (54.2%, p=0.001). The linear regression model tend to reduce their sleep duration by roughly 22 minutes in female gender, 66 minutes in participants with hyperlipidemia, and 70 minutes in participants with poor sleep quality. Conclusions: Short sleep duration per night was prevalent, it affects one in every 3 Saudi adults. Long sleep duration of more than 9 hours was associated with increased comorbid conditions.

The effects of age and gender on the prevalence of insomnia in a sample of the Saudi population

ABSTRACT Objectives: The aim of this study was to determine the prevalence of insomnia among the Saudi adult population. Study design: A cross-sectional insomnia survey was conducted at King Abdulaziz Medical City (KAMC) in Riyadh, Saudi Arabia. The presence of insomnia was defined by difficulty initiating sleep, early morning awakening, or frequent awakening, in addition to the second-day effect in the form of fatigue, tiredness, or changes in the mode because of lack of sleep. Results: The crude prevalence of insomnia was 77.7% (95% CI = 75.9–79.5%). The gender-adjusted prevalence of insomnia was higher for females, 88.7% (95% CI = 86.4–90.7%) than for males, 70.4% (95% CI = 67.8–72.9%), p-value = .001. The age-adjusted prevalence of insomnia was higher for the elderly, 93.7% (95% CI = 90.6–96.0%) than for the middle aged, 79.8% (95% CI = 77.4–82.1%), or for the young group, 64.2% (95% CI = 59.9–68.4%), p-value = .001. The Chi-square analyses revealed that (1) being elderly, widowed/divorced, females, or housewives, (2) having a lack of education, and (3) excessive tea consumption were significantly associated with elevated risks for insomnia (p-values < .05). Conclusions: Insomnia is most prevalent among Saudi females and the elderly Saudi population.

Symptoms of Daytime Sleepiness and Sleep Apnea in Liver Cirrhosis Patients

BACKGROUND/PROPOSE Sleep disturbance and excessive daytime sleepiness (EDS) have been reported in patients with hepatic cirrhosis with no hepatic encephalopathy (HE). The objective of this study was to evaluate daytime sleepiness and risk of obstructive sleep apnea (OSA) among liver cirrhosis patients. MATERIAL AND METHODS A cross-sectional study was conducted at King Abdulaziz Medical City (KAMC)-Riyadh over a period of six months, using a structured questionnaire that investigated: 1) Sleep patterns and daytime sleepiness using the Epworth Sleeping Scale (ESS), and 2) The risk for sleep apnea using the Berlin Questionnaire (BQ). We enrolled patients with a confirmed diagnosis of liver cirrhosis who were being followed at the hepatology and preliver transplant clinics. RESULTS We enrolled 200 patients with liver cirrhosis, 57.5% of whom were male. The mean age was 60 (± SD 12.2). The reported prevalence of EDS, OSA, and both EDS and OSA were 29.5%, 42.9%, and 13.6%, respectively. The prevalence of EDS was higher in patients with Hepatitis-C and patients with DM, who experienced short sleep duration. We did not find any association between the severity of liver disease and EDS or OSA as measured by Child-Pugh scores (CPS). CONCLUSIONS The risk of OSA and EDS is high among liver cirrhosis patients. Those patients with cirrhosis secondary to Hepatitis C are at higher risk of EDS and OSA. Both EDS and OSA affect patients designated as CPS Class A more frequently than patients designated as CPS Class B.Background/propose.

Erlotinib in patients with advanced non-small cell lung cancer in Middle Eastern population

Background: Although erlotinib is widely used in the management of non-small cell lung cancer (NSCLC), no prior studies were conducted in Middle Eastern population. Our study aims at evaluating erlotinib prospectively in this population. Patients and Methods: This open-label, prospective, single-arm, multicenter Phase IV clinical trial of erlotinib as single agent evaluated safety and efficacy of Erlotinib in Middle Eastern patients with advanced NSCLC. Results: A total of 56 patients were enrolled in five sites in Saudi Arabia. Majority of patients were males (60%) with median age of 57 years (34–80), Stage IV (98%), and adenocarcinoma (84%). Eastern Cooperative Oncology Group performance Status III (41.1%). Epidermal growth factor receptor (EGFR) mutations were present in 24 patients out of 36 patients tested (67%). The most common reported adverse events (AEs) were rash 36 (64%), diarrhea 29 (52%), fatigue 10 (18%), and anorexia 5 (9%). Grade 4 or 5 AEs were not observed. Complete response was achieved in 2 (3.6%) and overall disease control was 60.8%. Median overall survival (OS) was significantly longer in patients with EGFR mutation than wild type (20 vs. 3 months, P = 0.002). Progression-free survival was 10 months and significantly longer in patients with EGFR mutation than wild type (16 vs. 6 months, P = 0.037). Patients with unknown EGFR status had PSF and OS better than wild-type patients and worse than patients with EGFR mutation. Cox regression analysis showed that older age (P = 0.029, HR 1.064), EGFR wild type (P = 0.014, hazard ratio [HR]: 8.497), and receiving radiation (P = 0.033, HR 6.433) significantly increase risk of death for patients receiving erlotinib. Conclusion: Erlotinib has efficacy and safety profile in Middle Eastern population similar to the reported literature. The empiric use of erlotinib in patients with unknown EGFR status in our patient population is warranted due to high prevalence of the mutation. However, it should not be used in confirmed wild-type disease.

Impact of GI Tumor Board on Patient Management and Adherence to Guidelines

Purpose As the burden of cancer on the population and the health care system continues to increase with more complicated treatment options, the need for multidisciplinary teams to be as efficient as possible becomes more vital. Our study aimed to evaluate the consistency of GI Tumor Board (GI TB) recommendations with international guidelines, the adherence of physicians involved in patient care to TB recommendations, and the impact on the management of patients. Methods A prospective cohort study was conducted from January to June 2016 at our institution, which is a major tertiary hospital that provides comprehensive cancer care. All cases presented at the GI TB during this period were included. Data regarding adherence to National Comprehensive Cancer Network guidelines, adherence to TB recommendations, and changes made to the management of patients were collected weekly from the GI TB in a data collection form. Results Of the 104 patients included, 57 (55%) were males and the median age was 58 (16 to 85) years. Colorectal cancer was the most common diagnosis, in 65 patients (63%). Nearly one-half of cases (45%) were stage IV cancers. Starting new treatment was recommended for 72 patients (69%). Further investigations were requested for 15 patients (14%). For imaging, 24 recommendations (23%) were made. Adherence to National Comprehensive Cancer Network guidelines was observed in 97% of total recommendations. New findings were found in pathology (11%), radiology (13%), and staging (4%). Management plans were changed in 37 cases (36%). Over a 3-month period after presentation to the GI TB, most of the recommendations (87%) were performed. Conclusion A multidisciplinary tumor board enhances the adherence to guidelines and has an impact on patient management in approximately one-third of patients. Among physicians, adherence to recommendations of the TB was high.

The prevalence of abnormal leukocyte count, and its predisposing factors, in patients with sickle cell disease in Saudi Arabia

Introduction High white blood cell (WBC) count is an indicator of sickle cell disease (SCD) severity, however, there are limited studies on WBC counts in Saudi Arabian patients with SCD. The aim of this study was to estimate the prevalence of abnormal leukocyte count (either low or high) and identify factors associated with high WBC counts in a sample of Saudi patients with SCD. Methods A cross-sectional and retrospective chart review study was carried out on 290 SCD patients who were routinely treated at King Fahad Hospital in Hofuf, Saudi Arabia. An interview was conducted to assess clinical presentations, and we reviewed patient charts to collect data on blood test parameters for the previous 6 months. Results Almost half (131 [45.2%]) of the sample had abnormal leukocyte counts: low WBC counts 15 (5.2%) and high 116 (40%). High WBC counts were associated with shortness of breath (P=0.022), tiredness (P=0.039), swelling in hands/feet (P=0.020), and back pain (P=0.007). The mean hemoglobin was higher in patients with normal WBC counts (P=0.024), while the mean hemoglobin S was high in patients with high WBC counts (P=0.003). After adjustment for potential confounders, predictors of high WBC counts were male gender (adjusted odds ratio [aOR]=3.63) and patients with cough (aOR=2.18), low hemoglobin (aOR=0.76), and low heart rate (aOR=0.97). Conclusion Abnormal leukocyte count was common: approximately five in ten Saudi SCD patients assessed in this sample. Male gender, cough, low hemoglobin, and low heart rate were associated with high WBC count. Strategies targeting high WBC count could prevent disease complication and thus could be beneficial for SCD patients.
