Objectives: For COVID-19-related respiratory failure, noninvasive respiratory assistance via a high-flow nasal cannula (HFNC), helmet, and face-mask noninvasive ventilation is used. However, which of these options is most effective is yet to be determined. This study aimed to compare the three techniques of noninvasive respiratory support and to determine the superior technique., Design: A randomized control trial with permuted block randomization of nine cases per block for each parallel, open-labeled arm., Setting and Patients: Adult patients with COVID-19 with a Pa o2 /F io2 ratio of less than 300, admitted between February 4, 2021, and August 9, 2021, to three tertiary centers in Oman, were studied., Interventions: This study included three interventions: HFNC ( n = 47), helmet continuous positive airway pressure (CPAP; n = 52), and face-mask CPAP ( n = 52)., Measurements and Main Results: The endotracheal intubation rate and mortality at 28 and 90 days were measured as the primary and secondary outcomes, respectively. Of the 159 randomized patients, 151 were analyzed. The median age was 52 years, and 74% were men. The endotracheal intubation rates were 44%, 45%, and 46% ( p = 0.99), and the median intubation times were 7.0, 5.5, and 4.5 days ( p = 0.11) in the HFNC, face-mask CPAP, and helmet CPAP, respectively. In comparison to face-mask CPAP, the relative risk of intubation was 0.97 (95% CI, 0.63-1.49) for HFNC and 1.0 (95% CI 0.66-1.51) for helmet CPAP. The mortality rates were 23%, 32%, and 38% at 28 days ( p = 0.24) and 43%, 38%, and 40% ( p = 0.89) at 90 days for HFNC, face-mask CPAP, and helmet CPAP, respectively. The trial was stopped prematurely because of a decline in cases., Conclusions: This exploratory trial found no difference in intubation rate and mortality among the three intervention groups for the COVID-19 patients with hypoxemic respiratory failure; however, more evidence is needed to confirm these findings as the trial was aborted prematurely., Competing Interests: Dr. Al Hashim, Dr. Burad, Dr. Chandwani, Dr. R.

The prevalence and incidence of asthma are increasing globally because of genetic and environmental influences. Prevalence of asthma in the Gulf has been reported to range from 4.7% to 32.0% and has a substantial economic burden. In this paper, we summarize current asthma management guidance for adults, present insights, and recommendations by key opinion leaders (KOLs) in the Gulf region, and key performance indicators for guiding clinical practice for asthma diagnosis, management, and treatment in the Gulf. While it is recommended that the Global Initiative for Asthma (GINA) guidelines should be followed wherever possible for the management of asthma, KOLs in the Gulf region have presented additional recommendations based on regional challenges and insights. There is a need for better diagnosis using objective testing, increased efforts in tackling the burden of comorbidities in the region, and greater provision of the necessary tools for phenotyping severe asthma. Furthermore, there is a need for greater education for physicians regarding asthma treatment, including the importance of inhaled-corticosteroid-containing controller medication. Regionally, there is also a need for specialist asthma clinics and asthma educators, which would serve to educate physicians and their patients as well as to improve the management of patients. Finally, the use of asthma registries, digital devices, and electronic templates would be of benefit in the management of asthma patients in the region., Competing Interests: NB has received speaker honoraria and sponsorship to attend conferences from AstraZeneca, Boehringer Ingelheim, GSK, Pfizer, and Novartis.

Background: While crucial to the assessment and improvement of asthma control, insights on treatment practices in patients with severe diseases across Gulf nations are lacking. This observational study describes the treatment patterns of adolescents and adults with severe asthma across four countries of the Gulf region and evaluates current levels of asthma control; quality of life (QoL); exacerbation frequency; and the application of cellular, protein, and respiratory biomarkers in assessing asthma severity and inflammation., Methods: Patients (aged >12 years, body weight ≥40 kg) with clinician-diagnosed, severe asthma (guided by the 2018 Global Initiative for Asthma definition) were included in this cross-sectional, multicenter, observational study conducted in the four Gulf countries of Kuwait, Oman, Qatar, and the United Arab Emirates. Data on demographics, treatment patterns, and laboratory parameters (blood eosinophil count [BEC], levels of serum immunoglobulin E [IgE], and fractional exhaled nitric oxide [FeNO]) were extracted from the medical records of patients during a 12-month retrospective period and transcribed onto case report forms. At the Enrollment visit, patients assessed their asthma control and QoL with the self-administered Asthma Control Questionnaire (ACQ) and a standardized version of the Asthma Quality of Life Questionnaire (AQLQ(S)), respectively., Results: Among the 243 patients analyzed, (mean [standard deviation (SD)] age, 48.4 [13.9] years; female, 67.5%), the inhaled corticosteroid (ICS)/long-acting β 2 agonist (LABA) combination was the most prescribed asthma medication (n = 240; 98.8%). Most patients were classified as "uncontrolled," (n = 173; 71.2%) and the majority (n = 206; 84.8%) experienced ≥1 exacerbation(s) in the preceding 12 months. The mean (SD) ACQ score was 2.1 (1.2), which indicated uncontrolled asthma, and the mean (SD) total AQLQ(S) score was 4.7 (1.4), suggesting "some limitation" in overall QoL. BECs during the 12-month period were elevated in most patients (>300 cells/μL [n = 183; 41.7%], 150-300 cells/μL [n = 138; 31.4%], <150 cells/μL [n = 118; 26.9%]), suggesting an eosinophilic asthma phenotype, although no standardized threshold by which to define eosinophilia has yet been confirmed. This study revealed that the biomarkers BEC, serum IgE, and FeNO concentrations were obtained inconsistently by the participating centers., Conclusions: Despite recommended ICS/LABA therapy being prescribed to most patients for their severe disease, the majority experienced uncontrolled asthma and exhibited elevated BECs. These findings indicate the need for enhanced treatment strategies to improve and sustain asthma control in the Gulf region., (© 2022 The Author(s).)

Objectives: Small-bore pigtail catheters are now being used more frequently for draining pleural effusions. This study aimed to measure the efficacy, safety, and tolerability of these devices in different clinical conditions., Methods: We retrospectively collected data from 141 patients with pleural effusions of various etiologies who underwent ultrasound-guided pigtail catheter insertion at Sultan Qaboos University Hospital, Muscat, Oman., Results: The majority 109 (77.3%) of patients had exudates. The mean age was 50.0±18.6 years in patients with exudates and 67.3±15.5 in patients with transudates ( p < 0.001). There was no significant difference ( p = 0.232) in the median drainage duration between exudates (6.0 days) and transudates (4.5 days). The incidence of pain requiring regular analgesics, pneumothorax, and blockage were 36.2% (n = 51), 2.8% (n = 4), and 0.7% (n = 1), respectively. The overall success rate of pleural effusion drainage was 90.1%. Among the 109 cases of exudative pleural effusion, 89.0% were successful compared to a 93.8% success rate among patients with transudative effusion ( p = 0.737). Short-term success rates were high in all causes of effusions: lung cancer (100%), metastasis (90.0%), pleural infections (83.3%), cardiac failure (94.7%), renal disease (85.7%), and liver disease (100%)., Conclusions: Ultrasound-guided pigtail catheter insertion is an effective, comfortable, and safe method of draining pleural fluid. It should be considered as the first intervention if drainage of a pleural effusion is clinically indicated., (The OMJ is Published Bimonthly and Copyrighted 2021 by the OMSB.)

Massive hemoptysis is uncommon in mitral stenosis in contemporary practice. We report a patient without any previous illness presenting with life-threatening pulmonary hemorrhage, who was initially managed as cryptogenic hemoptysis. Once mitral stenosis was confirmed, the patient underwent mitral valve replacement with total and complete cessation of bleeding., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Al-Kindi et al.)

The COVID-19 pandemic continues to move at record speed. Health systems and hospitals worldwide face unprecedented challenges to effectively prepare and respond to this extraordinary health crisis and anticipated surge. Hospitals should confront these unparalleled challenges with a comprehensive, multidisciplinary, coordinated, and organized strategy. We report our experience with the systematic application of the "4S" principle to guide our institutional preparedness plan for COVID-19. We used an innovative "virtual interdisciplinary COVID-19 team" approach to consolidate our hospital readiness., (The OMJ is Published Bimonthly and Copyrighted 2020 by the OMSB.)

Sarcoidosis, a systemic granulomatous disease of unknown cause, has been described worldwide and in all populations with notable differences in clinical characteristics, organ involvement, disease severity, and prognosis among different ethnic and racial groups. While the exact prevalence of sarcoidosis in the Middle East is unknown, studies from various countries in the region have reported the clinical characteristics of affected patients, along with a few anecdotal reports. A search of the MEDLINE and Google Scholar databases was conducted for relevant English-language articles using the terms "sarcoidosis" and "Middle East" or "sarcoidosis" and "Arabs." Subsequently, the names of individual countries were used as search terms, replacing "Middle East." Overall, the clinical picture of patients with sarcoidosis in the Middle East is similar to that reported elsewhere; for example, the disease was more frequent among females and respiratory complaints were the predominant symptoms. Within the region, most patients from Oman were older and female, with arthralgia, hypercalcemia, and eye involvement being more common. Constitutional symptoms were frequent, especially among patients from Iran. Cough was more common among patients from Kuwait and Iran, while dyspnea was the predominant symptom for Saudi patients. Erythema nodosum was more common in the Turkish population. Clustering was seen in patients with Stage I and II of the disease in all countries except Oman. Apart from those in Iran, the prognosis of most patients from the Middle East was excellent., Competing Interests: There are no conflicts of interest.

Background Adverse drug events from preventable medication errors can result in patient morbidity and mortality, and in cost to the healthcare system. Medication reconciliation can improve communication and reduce medication errors at transitions in care. Objective Evaluate the impact of medication reconciliation and counselling intervention delivered by a pharmacist for medical patients on clinical outcomes 30 days after discharge. Setting Sultan Qaboos University Hospital, Muscat, Oman. Methods A randomized controlled study comparing standard care with an intervention delivered by a pharmacist and comprising medication reconciliation on admission and discharge, a medication review, a bedside medication counselling, and a take-home medication list. Medication discrepancies during hospitalization were identified and reconciled. Clinical outcomes were evaluated by reviewing electronic health records and telephone interviews. Main outcome measures Rates of preventable adverse drug events as primary outcome and healthcare resource utilization as secondary outcome at 30 days post discharge. Results A total of 587 patients were recruited (56 ± 17 years, 57% female); 286 randomized to intervention; 301 in the standard care group. In intervention arm, 74 (26%) patients had at least one discrepancy on admission and 100 (35%) on discharge. Rates of preventable adverse drug events were significantly lower in intervention arm compared to standard care arm (9.1 vs. 16%, p = 0.009). No significant difference was found in healthcare resource use. Conclusion The implementation of an intervention comprising medication reconciliation and counselling by a pharmacist has significantly reduced the rate of preventable ADEs 30 days post discharge, compared to the standard care. The effect of the intervention on healthcare resource use was insignificant. Pharmacists should be included in decentralized, patient-centred roles. The findings should be interpreted in the context of the study's limitations.

Aminoacyl-tRNA synthetases (ARSs) canonical function is to conjugate specific amino acids to cognate tRNA that are required for the first step of protein synthesis. Genetic mutations that cause dysfunction or absence of ARSs result in various neurodevelopmental disorders. The human phenylalanine-tRNA synthetase (PheRS) is a tetrameric protein made of two subunits coded by FARSA gene and two subunits coded by FARSB gene. We describe eight affected individuals from an extended family with a multisystemic recessive disease manifest as a significant growth restriction, brain calcifications, and interstitial lung disease. Genome-wide linkage analysis and whole exome sequencing identified homozygosity for a FARSB mutation (NM&#95;005687.4:c.853G > A:p.Glu285Lys) that co-segregate with the disease and likely cause loss-of-function. This study further implicates FARSB mutations in a multisystem, recessive, neurodevelopmental phenotype that share clinical features with the previously known aminoacyl-tRNA synthetase-related diseases., (© 2018 Wiley Periodicals, Inc.)
