Background: The DES-obstructive sleep apnea (DES-OSA) score uses morphological characteristics to predict the presence and severity of obstructive sleep apnea syndrome (OSAS).

Objectives: To validate DES-OSA scores on the Israeli population. To identify patients requiring treatment for OSAS. To evaluate whether additional parameters could improve the diagnostic value of DES-OSA scores.

Methods: We performed a prospective cohort study on patients attending a sleep clinic. Polysomnography results were examined independently by two physicians. DES-OSA scores were calculated. STOP and Epworth questionnaires were administered, and data on cardiovascular risk was extracted.

Results: We recruited 106 patients, median age 64 years, 58% male. DES-OSA scores were positively correlated with apnea-hypopnea index (AHI) (P < 0.001) and were significantly different between the OSAS severity groups. Interobserver agreement for calculating DES-OSA was very high between the two physicians (intraclass correlation coefficient 0.86). DES-OSA scores ≤ 5 were associated with high sensitivity and low specificity (0.90 and 0.27, respectively) for moderate to severe OSAS. In univariate analysis, only age was significantly correlated with the presence of OSAS (OR 1.26, P = 0.01). Age older than 66 years as a single point in the DES-OSA score slightly improved the sensitivity of the test.

Conclusions: DES-OSA is a valid score based solely on physical examination, which may be useful for excluding OSAS requiring therapy. DES-OSA score ≤ 5 effectively ruled out moderate to severe OSAS. Age older than 66 years as an extra point improved the sensitivity of the test.

Background: Severe asthma affects up to 20,000 citizens of Israel. Novel biological therapies, which individually have been proven to reduce asthma morbidity in clinical trials, have become available in recent years. Comparative data among different drugs are scarce.

Objectives: To describe and compare the clinical outcomes of biological therapies in severe asthma patients treated at Shamir Medical Center.

Methods: We conducted a cohort study based on a review of cases treated with monoclonal antibodies for severe asthma at our center. Data were extracted for demographics, eosinophil count, lung function (FEV1), exacerbation rate, and median dose of oral prednisone. Between-drug comparison was conducted by repeated measures ANOVA.

Results: The cohort included 62 patients receiving biological therapy. All biologic drugs were found to reduce exacerbation rate [F(1, 2) = 40.4, P < 0.0001] and prednisone use [F(1, 4) = 16, P < 0.001] significantly. ANOVA revealed no difference of efficacy endpoints between the different drugs. Eosinophil count was significantly reduced post-biologic treatment in the anti-interleukin-5 agents (P < 0.001) but not under treatment with omalizumab and dupilumab.

Conclusions: All of the biological therapies were effective for improving clinical outcomes. None of the agents was clearly superior to any other. These data emphasize the need for severe asthma patients to be seen by pulmonary medicine specialists and offered, where appropriate, biological therapies.

Background: Studies in lung transplantation demonstrate that the ancestry and gender dissimilarities of donor–recipients lead to a decrease in survival of the recipient. 

Objectives: To evaluate the survival of lung transplant recipients in Israel based on whether the donors and recipients are of Jewish or Arab ancestry as well as survival based on gender match or mismatch.

Methods: We performed a retrospective observational cohort study of 345 lung transplant recipients at the Rabin Medical Center, Petah Tikva, Israel between January 1997 and January 2013. We compared the survival of lung transplant recipients in two ancestry categories: ancestry matched (Jewish donors to Jewish recipients or Arab donors to Arab recipients) and ancestry mismatched (Jewish donors to Arab recipients and vice versa). We also compared the survival among the four gender donor and recipient combinations (male to male, female to female, male to female, and female to male). 

Results: Survival analysis revealed no significant differences between the two ancestry groups (P = 0.51) and among the four gender combinations (P = 0.58). On Cox multivariate analysis, younger donor age was the only significant parameter for longer survival (hazards ratio 1.025, 95% confidence interval 1.012–1.037).

Conclusions: Gender and ancestry mismatches in these two Israeli populations do not appear to alter the clinical outcomes following lung transplantation.

Background: Blunt chest trauma can cause severe acute pulmonary dysfunction due to hemo/pneumothorax, rib fractures and lung contusion.

Objectives: To study the long-term effects on lung function tests after patients' recovery from severe chest trauma.

Methods: We investigated the outcome and lung function tests in 13 patients with severe blunt chest trauma and lung contusion.

Results: The study group comprised 9 men and 4 women with an average age of 44.6 ± 13 years (median 45 years). Ten had been injured in motor vehicle accidents and 3 had fallen from a height. In addition to lung contusion most of them had fractures of more than three ribs and hemo/pneumothorax. Ten patients were treated with chest drains. Mean intensive care unit stay was 11 days (median 3) and mechanical ventilation 19 (0–60) days. Ten patients had other concomitant injuries. Mean forced expiratory volume in the first second was 81.2 ± 15.3%, mean forced vital capacity was 85 ± 13%, residual volume was 143 ± 33.4%, total lung capacity was 101 ± 14% and carbon monoxide diffusion capacity 87 ± 24. Post-exercise oxygen saturation was normal in all patients (97 ± 1.5%), and mean oxygen consumption max/kg was 18 ± 4.3 ml/kg/min (60.2 ± 15%). FEV1[1]. was significantly lower among smokers (71.1 ± 12.2 vs. 89.2 ± 13.6%, P = 0.017). There was a non-significant tendency towards lower FEV1 among patients who underwent mechanical ventilation.

Conclusions: Late after severe trauma involving lung contusion, substantial recovery is demonstrated with improved pulmonary function tests. These results encourage maximal intensive care in these patients. Further larger studies are required to investigate different factors affecting prognosis.
