Corticosteroid Therapy for Critically Ill Patients with Middle East Respiratory Syndrome.

RATIONALE: Corticosteroid therapy is commonly used among critically ill patients with Middle East Respiratory Syndrome (MERS), but its impact on outcomes is uncertain. Analyses of observational studies often do not account for patients' clinical condition at the time of corticosteroid therapy initiation. OBJECTIVES: To investigate the association of corticosteroid therapy on mortality and on MERS coronavirus RNA clearance in critically ill patients with MERS. METHODS: ICU patients with MERs were included from 14 Saudi Arabian centers between September 2012 and October 2015. We performed marginal structural modeling to account for baseline and time-varying confounders. MEASUREMENTS AND MAIN RESULTS: Of 309 patients, 151 received corticosteroids. Corticosteroids were initiated at a median of 3.0 days (quartile 1 [Q1]-Q3, 1.0-7.0) from ICU admission. Patients who received corticosteroids were more likely to receive invasive ventilation (141 of 151 [93.4%] vs. 121 of 158 [76.6%]; P < 0.0001) and had higher 90-day crude mortality (112 of 151 [74.2%] vs. 91 of 158 [57.6%]; P = 0.002). Using marginal structural modeling, corticosteroid therapy was not significantly associated with 90-day mortality (adjusted odds ratio, 0.75; 95% confidence interval, 0.52-1.07; P = 0.12) but was associated with delay in MERS coronavirus RNA clearance (adjusted hazard ratio, 0.35; 95% CI, 0.17-0.72; P = 0.005). CONCLUSIONS: Corticosteroid therapy in patients with MERS was not associated with a difference in mortality after adjustment for time-varying confounders but was associated with delayed MERS coronavirus RNA clearance. These findings highlight the challenges and importance of adjusting for baseline and time-varying confounders when estimating clinical effects of treatments using observational studies.

Importance of adjusting dual-energy X-ray output for body size: an example from survivors of childhood acute lymphoblastic leukemia.

We compared DXA whole body and lumbar spine bone mineral density (BMD) using manufacturers software with a body size correction which derived bone mineral content (BMC) for bone area in survivors of acute lymphoblastic leukemia in Saudi Arabia (n = 51, mean age 13.5 y). With no corrections, 29 patients (57%) had lumbar spine BMD Z score < -1.0 and 21 (41%) had whole body BMD Z score < -2. After correction, only 6 (12%) had lumbar spine BMC Z score < -1.0 and 4 (8%) had whole body BMC Z score < -2. Agreement between the methods was "poor" by weighted κ analysis.

Obesity and metabolic syndrome in adolescent survivors of standard risk childhood acute lymphoblastic leukemia in Saudi Arabia.

BACKGROUND: This study estimated prevalence of unhealthy weight status and metabolic syndrome (MS) amongst Saudi survivors of standard risk ALL. PROCEDURE: We recruited 56 survivors, mean age 13.4 years (SD 4.1), a mean of 9.1 years (SD 4.1) post-diagnosis. The BMI for age was used to define weight status relative to national (Saudi) and international (Cole et al., Cole-IOTF, WHO, and CDC) reference data. We measured body composition by dual-energy X-ray absorptiometry (DXA), waist circumference, blood pressure, lipid profile (HDL-C, Triglycerides), fasting glucose and insulin. RESULTS: According to international definitions based on BMI for age, around half of the sample had unhealthy weight status. All of the approaches based on BMI for age underestimated overfatness, present in 27/51 (53%) of the sample according to DXA. Prevalence of MS was 7.1% (3/42 of those over 9-years old) and 5.4% (3/56) by applying the International Diabetes Federation (IDF) definition and National Cholesterol Education Program Third Adult Treatment panel Guidelines (NCEP III), respectively. However, MS by the NCEP III definition was present in 19% of the overweight and obese survivors and 7.1% of the sample had at least two of the components of MS. CONCLUSION: Unhealthy body weight and overfatness may be common amongst adolescent Saudi survivors of standard risk ALL, though overweight and obesity may be no more common than in the general Saudi adolescent population. Defining weight status using BMI underestimates overfatness. Ideally, body composition and cardiometabolic risk factors should be monitored at late effects clinics.

Appropriateness of pediatric hospitalization in a general hospital in Kuwait.

OBJECTIVES: To determine the rate of inappropriate pediatric admissions using the Pediatric Appropriateness Evaluation Protocol (PAEP) and to examine variables associated with inappropriateness of admissions. SUBJECTS AND METHODS: A prospective study was conducted in the Department of Pediatrics, Farwania General Hospital, Kuwait, to examine successive admissions for appropriateness of admission as well as several sociodemographic characteristics over a 5-month period (August 2010 to December 2010). A total of 1,022 admissions were included. RESULTS: Of the 1,022 admissions, 416 (40.7%) were considered inappropriate. Factors associated with a higher rate of inappropriate admission included older age of patients and self-referral. CONCLUSION: The rate of inappropriate hospitalization of children was high in Farwania Hospital, Kuwait, probably due to the relatively free health care services, parental preference for hospital care, easy access to hospital services, and insufficient education about the child's condition.

Parents' views on the acceptability of a COVID-19 vaccine for their children: A cross-sectional study in Abu Dhabi-United Arab Emirates.

BACKGROUND: The United Arab Emirates had approved the COVID-19 vaccine for children. Assessing parents' acceptance of the vaccine for their children will influence decision-making in the COVID-19 vaccine roll-out. METHOD: Parents registered inthe AbuDhabiDepartmentofEducation (12,000 families) were invitedtocompleteanonlinequestionnaire from 8th September 2021 to 17th October 2021. Out of the 12,000 families, 2510 (21%) participants answered the survey. The questionnaire investigated the parents' attitudes and beliefs regarding the COVID-19 vaccine. RESULTS: The vaccination rate among this group of respondents was high, with 2255 (89.9%) having received two doses and 1002 (45.5%) having already received a booster dose. Acceptance of the respondents to vaccinate their children was high, (75.1%) said they would vaccinate their children, with 64.4% reporting that they would immediately vaccinate their children if the vaccine were made available. Determinants of COVID-19 child vaccination acceptance included the respondent's vaccination status-i.e., if the respondent is already vaccinated (OR 4.96 [2.89-8.53]) or has taken the third dose (OR 2.37 [1.4-4.01])-their children's age (OR 1.11 [1.30-1.18] for older children), and their trust in the following information sources: the government (OR 2.53 [1.61-3.98]), health care providers (OR 1.98 [1.2-3.24]), or social media (OR 2.17 [1.22-3.88]). Increased level of education had a negative impact on the acceptance of giving the vaccine to children (OR 0.63 [0.52-0.77]); fear of side effects OR 0.000164 (0.000039-0.001) was another determinant. The main factor that encouraged parents to give their children the vaccine was to protect their child's health as reported by 1537 (55.5%) participants. CONCLUSION: The Abu Dhabi community is highly accepting of the vaccine for their children. Future studies of how this vaccine acceptance can influence the pandemic are needed.

Implementing the comprehensive unit-based safety program model to improve the management of mechanically ventilated patients in Saudi Arabia.

BACKGROUND: Ventilator-associated events are common in mechanically ventilated patients. They are associated with more days on mechanical ventilation, longer intensive care unit (ICU) stay, and increased risk of mortality. Theoretically, interventions that prevent ventilator-associated events should also reduce associated morbidity. We evaluated the Comprehensive Unit-based Safety Program approach to improve the care of mechanically ventilated patients. METHODS: All mechanically ventilated patients admitted to the ICU between October 1, 2015, and October 31, 2016, were prospectively monitored for the development of ventilator-associated events according to the National Healthcare Safety Network criteria. A process care bundle (endotracheal intubation with subglottic suctioning, head-of-bed elevation ≥30°, target sedation scores, daily spontaneous awakening trials, spontaneous breathing trials), daily delirium assessment, and an early mobility protocol were instituted. The bundle compliance, ventilator-associated events rates, ICU length of stay, and mortality rate were noted. The database allowed viewing of current rates, trends, and averages of all participating sites. RESULTS: In the study period, 2,321 patients were admitted to the ICU, and 1,231 required mechanical ventilation (10,342 ventilator days). There were 115 ventilator-associated events: 82 ventilator-associated conditions, 15 infection-related ventilator-associated conditions, and 18 possible cases of ventilator-associated pneumonia. The ICU mortality rate was 13.3%, compared with 28.7% for those mechanically ventilated patients with ventilator-associated events (P = .0001). There was increased compliance for spontaneous awakening trials (51.5%-76.9%, P = .0008) and spontaneous breathing trials (54.2%-72.2%, P = .02) and a decrease in infection-related ventilator-associated conditions (4.2-3.5 per 1,000 days), possible cases of ventilator-associated pneumonia (2.1-1.7 per 1,000 days), ICU mortality (45.3%-19.1%, P = .045), and ventilator-associated events associated mortality rates (33.3%-8.3%, P < .37). Physical therapy participation and mobility were 60.8% and 26.4%, respectively. CONCLUSION: The implementation of a multipronged program like the Comprehensive Unit-based Safety Program could improve the care processes and outcomes of mechanically ventilated patients.
