Few recent comparative data exist on smoking habits in the Middle East and North Africa (MENA) region. The objective of this analysis was to evaluate smoking patterns in a large general population sample of individuals aged ≥ 40 years in ten countries in the region (Algeria, Egypt, Jordan, Lebanon, Morocco, Saudi Arabia, Syria, Tunisia, Turkey and United Arab Emirates), together with Pakistan, using a standardised methodology. A random sample of 457,258 telephone numbers was generated and called. This identified 65,154 eligible subjects, of whom 62,086 agreed to participate. A screening questionnaire was administered to each participant, which included six questions relating to cigarette consumption and waterpipe use. The age- and gender-adjusted proportion of respondents reporting current or past smoking of cigarettes or waterpipes was 31.2% [95% CI: 30.9-31.6%]. This proportion was significantly higher (p < 0.001) in men (48.0%) than in women (13.8%), but no relevant differences were observed between age groups. Smoking rates were in general lowest in the Maghreb countries and Pakistan and highest in the Eastern Mediterranean countries, ranging from 15.3% in Morocco to 53.9% in Lebanon. Consumption rates were 28.8% [28.4-29.2%] for cigarette smoking and 3.5% [3.4-3.6%] for waterpipe use. Use of waterpipes was most frequent in Saudi Arabia (8.5% of respondents) but remained low in the Maghreb countries (< 1.5%). Cumulative cigarette exposure was high, with a mean number of pack · years smoked of 18.5 ± 20.5 for women and 29.1 ± 26.2 for men. In conclusion, smoking is a major health issue in the MENA region.

Large differences in COVID‐19 death rates exist between countries and between regions of the same country. Some very low death rate countries such as Eastern Asia, Central Europe or the Balkans have a common feature of eating large quantities of fermented foods. Although biases exist when examining ecological studies, fermented vegetables or cabbage were associated with low death rates in European countries. SARS‐CoV‐2 binds to its receptor, the angiotensin converting enzyme 2 (ACE2). As a result of SARS‐Cov‐2 binding, ACE2 downregulation enhances the angiotensin II receptor type 1 (AT 1 R) axis associated with oxidative stress. This leads to insulin resistanceas well as lung and endothelial damage, two severe outcomes of COVID‐19. The nuclear factor (erythroid‐derived 2)‐like 2 (Nrf2) is the most potent antioxidant in humans and can block the AT 1 R axis. Cabbage contains precursors of sulforaphane, the most active natural activator of Nrf2. Fermented vegetables contain many lactobacilli, which are also potent Nrf2 activators. Three examples are given: Kimchi in Korea, westernized foods and the slum paradox. It is proposed that fermented cabbage is a proof‐of‐concept of dietary manipulations that may enhance Nrf2‐associated antioxidant effects helpful in mitigating COVID‐19 severity.

COPD is a progressive pulmonary disease which may have a profound impact on general health status and quality of life. This article presents data on the burden of COPD obtained from the BREATHE study in the Middle East, North Africa and Pakistan. This study was a large general population survey of COPD conducted in eleven countries of the region using a standardised methodology. A total of 62,086 subjects were screened, of whom 2,187 fulfilled the "epidemiological" definition of COPD. Data on symptoms, perceived disease severity, impact on work, limitations in activities and psychological distress were collected. 1,392 subjects were analysable of whom 661 (47.5%) reported experiencing an exacerbation of their respiratory condition, 49.4% reported comorbidities and 5.5% reported severe breathlessness as measured with the MRC breathlessness questionnaire. The degree of breathlessness, as well as the perceived severity, was correlated with the overall disease impact as measured with the COPD Assessment Test (p < 0.001). 374 subjects (28.4%) reported that their respiratory condition prevented them from working and this proportion rose to 47.8% in subjects who perceived their respiratory condition as severe. 47.9% of subjects reported difficulties in normal physical exertion, 37.5% in social activities and 31.7% in family activities. Psychological distress was reported by between 42.3% and 53.2% of subjects, depending on the item. In conclusion, the burden of COPD is important, and covers central aspects of daily life. For this reason, physicians should take time to discuss it with their patients, and ensure that the management strategy proposed addresses all their needs.

Chronic obstructive pulmonary disease (COPD) is a potentially severe chronic progressive respiratory condition requiring long-term treatment and frequently involving episodic hospitalisations to manage exacerbations. The objective of this analysis was to document diagnosis, evaluation, treatment and management of COPD-related respiratory symptoms in 1,392 subjects fulfilling an epidemiological definition of COPD identified in a general population sample of 62,086 individuals aged ≥ 40 years in ten countries in the Middle East and North Africa region (Algeria, Egypt, Jordan, Lebanon, Morocco, Saudi Arabia, Syria, Tunisia, Turkey and United Arab Emirates), together with Pakistan. 442 subjects (31.8%) claimed to have received a diagnosis of COPD from a physician and 287 (20.6%) had undergone spirometry in the previous year. Use of specific treatments for respiratory symptoms was reported by 218 subjects (15.7%). Use of inhaled long-acting bronchodilators together with corticosteroids (53 subjects; 3.8%) and use of oxygen therapy (31 subjects; 2.3%) was very low. 852 subjects (61.2%) had consulted a physician about their respiratory condition at least once in the previous year, with a mean number of consultations of 3.4 ± 3.6. Moreover, 284 subjects (20.4%) had been hospitalised overnight for their COPD, with a mean of 2.3 ± 3.7 hospitalisations per year. Use of all healthcare resources was significantly higher (p < 0.001) in subjects with CAT scores ≥ 10 than in those with scores < 10, and greater in those with exacerbations than in those without. In conclusion, COPD in the region is under-diagnosed, inadequately evaluated and inadequately treated. Nonetheless, COPD symptoms are responsible for considerable healthcare consumption, with high levels of physician consultation and hospitalisation.

Although COPD is a debilitating pulmonary condition, many studies have shown awareness of the disease to be low. This article presents data on attitudes and beliefs about COPD in subjects with respiratory symptoms participating in the BREATHE study in the Middle East and North Africa region. This study was a large general population survey of COPD conducted in ten countries of the region (Algeria, Egypt, Jordan, Lebanon, Morocco, Saudi Arabia, Syria, Tunisia, Turkey and United Arab Emirates), together with Pakistan, using a standardised methodology. A total of 62,086 subjects were screened, of whom 2,187 fulfilled the "epidemiological" definition of COPD. A detailed questionnaire was administered to these subjects, which documented knowledge about the disease, attitudes to care, beliefs about COPD and satisfaction with treatment. 1,392 subjects were analysable. Overall, 58.6% of subjects claimed to be very well or adequately informed about their respiratory condition. Two-thirds of subjects reported receiving information about COPD from their physician and 10.6% from television; the internet was cited by 6% and other health professionals or patient associations by < 1%. Several inappropriate beliefs were identified, with 38.9% of respondents believing that there were no truly effective treatments, 73.7% believing that their respiratory condition would get progressively worse regardless of treatment and 29.6% being unsure what had caused their respiratory problems. Although 81% of respondents believed that smoking was the cause of most cases of COPD in general, only 51% accepted that it was the cause of their own respiratory problems. Treatment satisfaction was relatively high, with 83.2% of respondents somewhat or very satisfied with their physician's management, in spite of the fact that only 47.5% considered that their physician's advice had helped them manage their respiratory symptoms a lot. In conclusion, awareness of COPD in the region is suboptimal and treatment expectations are undervalued. Better patient education and more effective patient-physician communication are clearly required.

Introduction The aim of the study was to determine the prevalence of cardio‐metabolic risk factors in men under 30 in the United Arab Emirates. Methods This cross‐sectional observational study included 33 327 Emirati men aged 18‐29 attending an obligatory standardized medical examination between May 2015 and February 2017. Body mass index, fasting blood glucose, total cholesterol, triglycerides and blood pressure were assessed. Results Overall, 7720 subjects (24.4%) were overweight and 8835 (28.0%) obese. The age‐adjusted prevalence was 4.7% [95% CI: 4.4‐5.0] for diabetes, 41.3% [40.6‐41.9] for impaired fasting glucose, 5.5% [5.2‐5.8] for hypercholesterolaemia (total cholesterol ≥ 240 mg/dL), 11.5% [11.1%‐12.0%] for hypertriglyceridaemia (≥150 mg/dL) and 10.4% [10.0%‐10.8%] for hypertension (diastolic or systolic blood pressure—or both—above upper limit of normal). These conditions were already present in the youngest age groups and rise progressively and rapidly with age. Of the 26 648 subjects with valid data for all cardio‐metabolic risk factors, 16 563 subjects (62.2%) presented ≥ 1 factor, 6392 subjects presented ≥2 factors (24.0%) and 63 (0.2%) presented all five. Patients who were obese were more likely to present multiple cardio‐metabolic risk factors and to have hypertension (P < 0.0001). All cardio‐metabolic risk factors were highly correlated with each other. Conclusions This national cohort study in the UAE revealed that obesity, diabetes, impaired fasting glucose, hypercholesterolaemia, triglyceridaemia and hypertension are already highly prevalent in young adulthood. Public health initiatives are required to address these and to anticipate the future burden of diabetes and major cardiovascular disease for which these men are at high risk.

This study evaluates the direct costs of treating asthma in Abu Dhabi in the United Arab Emirates. Data was compiled for 2011 from health insurance claims covering all medical interventions or treatments coded as asthma. Costs were calculated from a health care perspective. The total direct cost of treating 139,092 asthma patients was estimated to be United Arab Emirates Dirhams (AED) 105 million (US$29 million), corresponding to around AED 750 per patient per annum. The total cost is principally generated by outpatient visits (>AED 85 million; 81% of the total cost). Ten point four percent of patients had made an emergency room visit. The cost per visit seems to be higher during hospital admissions (AED 7,123) compared to outpatient visits and emergency room visits. The direct cost of asthma medications was around AED 33 million (31% of the total cost). The economic burden of asthma in Abu Dhabi is high and the number of emergency visits suggests that the disease is not optimally controlled.

The effectiveness of the inactivated BBIBP-CorV vaccine against severe COVID-19 outcomes (hospitalization, critical care admission and death due to COVID-19) and its long-term effectiveness have not been well characterized among the general population. We conducted a retrospective cohort study using electronic health records of 3,147,869 adults, of which 1,099,886 vaccinated individuals were matched, in a 1:1 ratio to 1,099,886 unvaccinated persons. A Cox-proportional hazard model with time varying coefficients was used to assess the vaccine effectiveness adjusting for age, sex, comorbidity, ethnicity, and the calendar month of entry into the study. Our analysis showed that the effectiveness was 79.6% (95% CI, 77.7 to 81.3) against hospitalization, 86% (95% CI, 82.2 to 89.0) against critical care admission, and 84.1% (95% CI, 70.8 to 91.3) against death due to COVID-19. The effectiveness against these severe outcomes declined over time indicating the need for booster doses to increase protection against severe COVID-19 outcomes.
