We aimed to test the hypothesis that a lung ultrasound severity score (LUS) and assessment of left ventricular eccentricity index of the interventricular septum (LVEI) by focused heart ultrasound can predict extubation success in mechanically ventilated infants. We conducted a prospective study on premature infants less than 34 weeks' of gestation. LUS was performed on postnatal Days 3 and 7 by an investigator who was masked to infants' ventilator parameters. LVEI and pulmonary artery pressure (PAP) were measured at postnatal Day 3. A receiver operator curve was constructed to assess the ability to predict extubation success. Spearman correlation was performed between LVEI and PAP. A total of 104 studies were performed to 66 infants; of them 39 had mild and 65 had moderate-severe lung disease.LUS predicted extubation success with a sensitivity and a specificity of 91% and 69%, respectively. Area under the curve was 0.83 (CI: 0.75-0.91). LVEI did not differ between infants that succeeded and failed extubation. It correlated with PAP during systole (r = .66). We conclude that LUS predicts extubation success in mechanically ventilated preterm infants whereas LVEI correlates with high PAP.

Method The current study applied e-Delphi technique via online self-administered questionnaire was distributing to headquarter, and 16 health affairs directorates spanning 75 hospitals and specialized health centers, 24 primary health-care centers, 2 health-care clusters, and 5 medical cities. In addition, community involvement was represented by 26 organizations: 7 universities, 9 scientific health associations, 5 charitable associations, and 5 key Saudi health partner organizations. Research field’s prioritization was performed by ranking weighed mean aggregate score via application of the combined consensus and metrics-based approach. Then the top five research topics were analyzed, verified, refined and classified into specific health research themes. Results The study included 2252 participants and attained a 90% response rate. The study deliverables were listed into two research priority domains: health system research priorities (1st agenda) and diseases and health problems priorities (2nd agenda). Overall, the types of the top five research priorities in the first agenda included service delivery (40.9%), health workforce (14.4%), governance and leadership (13.0%) ,preparedness and response to disasters and emergency (10.2%), health information systems (9.3%), access to essential medicines products and vaccines (6.97%), and financing (5.1%). On the other hand, the top five research priority areas in the second agenda were non-communicable diseases (16.9%), child and neonatal health (15.9%), medications (13.6%), women health (10.4%), dental health (10.4%). furthermore, biomedical and radiology technology and devices (5.6%), communicable diseases (3.7%), nutrition (3.2%), trauma and general management (3.2%), innovative approaches (2.4%), emergency management (2.7%), physical therapy and rehabilitation (2.3%), public health (2.3%), holistic approaches to health and wellness, behavior and lifestyle (1.5%), environmental health (0.6%),pilgrims’ health (0.6%), geriatric health (0.3%), and family medicine (0.3%). Conclusion Adequate description of the stakeholders and methodology can strengthen legitimacy and credibility and maximize the impact of the priority-setting process. Involvement of policymakers, researchers and funding organizations increases the opportunity of translation into actual research, supports redesigning the research landscape and ensures uptake of results and integration.

Objective: To test the hypothesis that a lung ultrasound severity score (LUSsc) and assessment of left ventricular eccentricity index of the interventricular septum (LVEI) by focused heart ultrasound can predict extubation success in mechanically ventilated preterm infants with respiratory distress syndrome (RDS). Design Prospective observational study of premature infants <34 weeks of gestation age supported with mechanical ventilation due to RDS. LUSsc and LVEI were performed on postnatal days 3 and 7 by an investigator who was masked to infants ventilator parameters and clinical conditions. RDS was classified based on LUSsc into mild (score 0-9) and moderate-severe (score 10-18). A receiver operator curve was constructed to assess the ability to predict extubation success. Pearson correlation was performed between LVEI and pulmonary artery pressure (PAP). Setting Level III neonatal intensive care unit, Cairo, Egypt. Results A total of 104 studies were performed to 66 infants; of them 39 had mild RDS (LUSsc 0-9) and 65 had moderate-severe RDS (score ≥10). LUSsc predicted extubation success with a sensitivity and a specificity of 91% and 69%; the positive and negative predictive values were 61% and 94%, respectively. Area under the curve (AUC) was 0.83 (CI: 0.75-0.91). LVEI did not differ between infants that succeeded and failed extubation. However, it correlated with pulmonary artery pressure during both systole (r=0.62) and diastole (r=0.53) and with hemodynamically significant patent ductus arteriosus (r=0.27 and r=0.46, respectively). Conclusion: LUSsc predicts extubation success in preterm infants with RDS whereas LVEI correlates with high PAP.
