RESUMEN
OBJECTIVES: This meta-analysis examined the effect of macrolides on resolution of community-acquired pneumonia (CAP) and interpretation of clinical benefit according to microbiology; emphasis is given to data under-reported countries (URCs). METHODS: This meta-analysis included 47 publications published between 1994 and 2022. Publications were analysed for 30-d mortality (58 759 patients) and resolution of CAP (6465 patients). A separate meta-analysis was done for the prevalence of respiratory pathogens in URCs. RESULTS: Mortality after 30 d was reduced by the addition of macrolides (odds ratio [OR] 0.65, 95% confidence interval [CI] 0.51-0.82). The OR for CAP resolution when macrolides were added to the treatment regimen was 1.23 (95% CI 1.00-1.52). In the CAP resolution analysis, the most prevalent pathogen was Streptococcus pneumoniae (12.68%; 95% CI 9.36-16.95%). Analysis of the pathogen epidemiology from the URCs included 12 publications. The most prevalent pathogens were S. pneumoniae (24.91%) and Klebsiella pneumoniae (12.90%). CONCLUSION: The addition of macrolides to the treatment regimen led to 35% relative decrease of 30-d mortality and to 23% relative increase in resolution of CAP.

Direct fed microbial may enhance the utilization of halophyte forages leading to improved animal growth and productivity. This study was conducted to evaluate Atriplex hay-based diet supplemented with yeast (Saccharomyces cerevisiae; SC) or bacteria (Bacillus subtilis and Lactobacillus casei; BAC) on lamb growth performance, digestibility, rumen fermentation, and carcass characteristics. Fifteen Barki lambs (90 ± 7 days of age and 18.6 ± 0.41 kg SE body weight; BW) were randomly assigned to three treatments for 120 days as follows: Control (basal diet without supplementation), SC and BAC diets, the basal diet supplemented with SC or BAC at 2 g/head/day, respectively. All lambs had similar dry matter (DM) intake, while lambs fed SC or BAC dies had higher (P < 0.05) total gain and average daily gain than those fed the control diet. Supplementation of SC or BC increased (P < 0.05) the digestibility of DM, organic matter, and acid detergent fiber, tended to decrease (P < 0.05) the urine N excretion and enhanced the N balance compared to the control. Ruminal pH, acetate, total volatile fatty acids concentrations, and bacterial protein were increased (P < 0.05), while creatinine and urea concentrations were decreased (P < 0.05) by both additives. Compared to other diets, the BAC diet reduced (P < 0.05) triglycerides, total lipids, kidney fat, and eye muscle fat. In conclusion, both additives resulted in similar positive growth performance and feed utilization, while only the BAC additive had a beneficial advantage in reducing the fat content of the carcass.

BACKGROUND: The extent of short-acting ß2-agonist (SABA) overuse in Africa remains poorly documented. As part of the SABA use IN Asthma (SABINA) III study, we assessed SABA prescriptions/clinical outcomes in 3 African countries. METHODS: Data on disease characteristics/asthma treatments were collected from patients (≥12 years) using electronic case report forms. Patients were classified by investigator-defined asthma severity (guided by the 2017 Global Initiative for Asthma) and practice type (primary/specialist care). Multivariable regression models analyzed associations between SABA prescriptions and outcomes. RESULTS: Data from 1778 patients (mean age, 43.7 years) were analyzed. Most patients were female (62.4%) and had moderate-to-severe asthma (63.3%), with 57.1 and 42.9% of patients treated in specialist and primary care, respectively. Asthma was partly controlled/uncontrolled in 66.2% of patients, with 57.9% experiencing ≥1 severe exacerbation in the previous 12 months. Overall, 46.5% of patients were prescribed ≥3 SABA canisters in the preceding 12 months (over-prescription); 26.2% were prescribed ≥10 canisters. SABAs were purchased over-the-counter by 32.6% of patients, of whom 79.3% had received SABA prescriptions; 71.9% and 40.1% for ≥3 and ≥10 canisters, respectively. Higher SABA prescriptions (vs. 1-2 canisters) were associated with increased incidence rate of severe exacerbations and lower odds of having at least partly controlled asthma (except 3-5 canisters). CONCLUSIONS: Findings from this African cohort of the SABINA III study indicate that SABA over-prescription and SABA over-the-counter purchase are common and associated with poor asthma-related outcomes. This highlights the need for healthcare providers/policymakers to align clinical practices with the latest treatment recommendations.

BACKGROUND: To gain a global perspective on short-acting ß2-agonist (SABA) prescriptions and associated asthma-related clinical outcomes in patients with asthma, we assessed primary health data across 24 countries in five continents. METHODS: SABINA III was a cross-sectional study that employed electronic case report forms at a study visit (in primary or specialist care) to record prescribed medication(s), over-the-counter (OTC) SABA purchases and clinical outcomes in asthma patients (≥12â years old) during the past 12â months. In patients with ≥1 SABA prescriptions, associations of SABA with asthma symptom control and severe exacerbations were analysed using multivariable regression models. RESULTS: Of 8351 patients recruited (n=6872, specialists; n=1440, primary care), 76.5% had moderate-to-severe asthma and 45.4% experienced ≥1 severe exacerbations in the past 12â months. 38% of patients were prescribed ≥3 SABA canisters; 18.0% purchased OTC SABA, of whom 76.8% also received SABA prescriptions. Prescriptions of 3-5, 6-9, 10-12 and ≥13 SABA canisters (versus 1-2) were associated with increasingly lower odds of controlled or partly controlled asthma (adjusted OR 0.64 (95% CI 0.53-0.78), 0.49 (95% CI 0.39-0.61), 0.42 (95% CI 0.34-0.51) and 0.33 (95% CI 0.25-0.45), respectively; n=4597) and higher severe exacerbation rates (adjusted incidence rate ratio 1.40 (95% CI 1.24-1.58), 1.52 (95% CI 1.33-1.74), 1.78 (95% CI 1.57-2.02) and 1.92 (95% CI 1.61-2.29), respectively; n=4612). CONCLUSIONS: This study indicates an association between high SABA prescriptions and poor clinical outcomes across a broad range of countries, healthcare settings and asthma severities, providing support for initiatives to improve asthma morbidity by reducing SABA overreliance.

Data of 651 lambs (68 Romanov, 49 Rahmani, 151 [â1/2 Rahmani X â1/2 Romanov) and 383 (â3/4 Rahmani and 1/4â Romanov]) were collected from Mehalet Mousa Farm, belonging to Animal Production Research Institute from the period of 2009 to 2016 to estimate phenotypic and genetic parameters. The traits studied were birth weight (BW), body weight at four week (BW4), body weight at eight weeks (BW8) and body weight at twelve weeks (BW12) or weaning weight. Least squares analysis of variance shows significance of the effects of breed groups, gender of lambs, birth type; month of birth and year of birth on all traits studied. Rahmani lambs had heavier BW, BW4, BW8 and BW12 while Romanov lambs had the lowest ones. The first generation (â1/2 Rhamani X â1/2 Romanov) had heavier body weights than Romanov and the second generation (â3/4 Rahmani X â1/4 Roamnov). Gender of lambs had highly significant effect on body weights. Males were significantly (p < 0.01) heavier than females for all traits studied. Least square means of BW, BW4, BW8 and BW12 for single lambs were 2.69, 10.43, 13.53 and 16.10 kg, respectively. Least square means of BW, BW4, BW8 and BW12 for twin lambs were 2.50, 9.37, 12.5 and 15.16 kg, respectively, while least square means of BW, BW4, BW8 and BW12 for triple lambs were 2.09, 7.86, 10.83 and 13.67 kg, respectively. Estimates of direct heritability measured by single trait animal model were 0.14, 0.23, 0.25 and 0.26 for BW, BW4, BW8 and BW12, respectively, and the corresponding measured by multi trait animal model were 0.17, 0.24, 0.32 and 0.36 for the same traits, respectively. All genetic and phenotypic correlations among different traits studied are positive and significant.
RESUMEN
OBJECTIVE: To screen children with influenza like illness or with symptoms of acute respiratory tract infections for influenza A virus infection - post swine flu pandemic era - using rapid influenza diagnostic tests. METHODS: During two years (2010 & 2011), 1 200 children with influenza like illness or acute respiratory tract infections (according to World Health Organization criteria) were recruited. Their ages ranged from 2-60 months. Nasopharyngeal aspirates specimens were collected from all children for rapid influenza A diagnostic test. RESULTS: Influenza A virus rapid test was positive in 47.5% of the children; the majority (89.6%) were presented with lower respiratory tract infections. Respiratory rate and temperature were significantly higher among positive rapid influenza test patients. CONCLUSIONS: Influenza A virus infection is still a major cause of respiratory tract infections in Egyptian children. It should be considered in all cases with cough and febrile episodes and influenza like symptoms even post swine flu pandemic.

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.

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.

Data on COPD-related healthcare resources use are rarely documented in developing countries. This article presents data on COPD-related healthcare resource consumption in the Middle East, North Africa and Pakistan and addresses the association of this variable with illness severity. A large survey of COPD was conducted in eleven countries of the region, namely Algeria, Egypt, Jordan, Lebanon, Morocco, Pakistan, Saudi-Arabia, Syria, Tunisia, Turkey and United Arab Emirates, using a standardised methodology. A total of 62,086 subjects were screened. This identified 2,187 subjects fulfilling the "epidemiological" definition of COPD. A detailed questionnaire was administered to document data on COPD-related healthcare consumption. Symptom severity was assessed using the COPD Assessment Test (CAT). 1,392 subjects were analysable. Physician consultations were the most frequently used healthcare resource, ranging from 43,118 [95% CI: 755-85,548] consultations in UAE to 4,276,800 [95% CI: 2,320,164-6,230,763] in Pakistan, followed by emergency room visits, ranging from 15,917 [95% CI: 0-34,807] visits in UAE to 683,697 [95% CI: 496,993-869,737] in Turkey and hospitalisations, ranging from 15,563 [95% CI: 7,911-23,215] in UAE to 476,674 [95% CI: 301,258-652,090] in Turkey. The use of each resource increased proportionally with the GOLD 2011 severity groups and was significantly (p < 0.0001) higher in subjects with more symptoms compared to those with lower symptoms and in subjects with exacerbations to those without exacerbations. The occurrence of exacerbations and the CAT score were independently associated with use of each healthcare resource. In conclusion, the BREATHE study revealed that physician consultation is the most frequently COPD-related healthcare resource used in the region. It showed that the deterioration of COPD symptoms and the frequency of exacerbations raised healthcare resource consumption.

Mediastinal lesions represent a diagnostic challenge and often require invasive approaches. We evaluated the role of radial probe endobronchial ultrasound-directed transbronchial needle aspiration (EBUS-TBNA) in the evaluation of mediastinal lesions. Between March 2005 to February 2006, 30 consecutive patients with enlarged mediastinal lymph nodes from unknown etiologies or suspicious for metastatic bronchogenic carcinoma and mediastinal masses underwent EBUS-TBNA and were clinically followed up. EBUS-TBNA was applied under topical anesthesia, midazolam sedation with a mean dose of 4.6+1.7 mg and prolonged the examination by 14.7 minutes on average. EBUS-directed TBNA was performed in 17 lymph nodes and 13 mediastinal masses, achieving specific diagnosis in 82.3% (14/17) and 84.6% (11/13) of examined lesions, respectively, with an overall yield of 83%. The sensitivity, specificity, and accuracy of EBUS-TBNA in distinguishing benign from malignant mediastinal lesions were 89.4%, 100%, and 93.3%, respectively. EBUS was well tolerated by most of the patients with no TBNA-related complications. In conclusion, EBUS-TBNA of mediastinal lesions is a minimally invasive safe diagnostic technique with high yield, even in the hands of those with initial experience. This initial study is convincing and stimulating for widespread application of EBUS-TBNA in Egyptian bronchoscopy practice.
