ABSTRACT
Background The SARS-Cov-2 Omicron variant demonstrates rapid spread but with reduced disease severity. Studies evaluating the lung imaging findings of Omicron infection versus non-Omicron variants remain lacking. Purpose To compare Omicron and Delta variants of SARS-CoV-2 by their chest CT radiological pattern, biochemical parameters, clinical severity and hospital outcomes after adjusting for vaccination status. Materials and Methods Retrospective study of hospitalized adult patients rt-PCR positive for SARS-CoV-2 with CT pulmonary angiography performed within 7 days of admission between December 1, 2021 and January 14, 2022. Blinded radiological analysis with multiple readers including RSNA CT classification, chest CT severity score (CT-SS, range 0 least severe to 25 most severe) and CT imaging features including bronchial wall thickening. Results 106 patients (Delta n=66, Omicron n=40) were evaluated (mean age, 58 years ± 18, 58 men). In the Omicron group, 37% (15/40) of CT pulmonary angiograms were categorized as normal compared with 15% (10/66) in the Delta group (p=.016). Using a generalized linear model to control for confounding variables, including vaccination status, Omicron variant infection was associated with a CT-SS that was lower by 7.2 points compared to infection with Delta variant (ß=-7.2, 95%CI: -9.9, -4.5; p <.001). Bronchial wall thickening was more common with Omicron than with the Delta variant (odds ratio [OR] 2.4, 95%CI: 1.01, 5.92, p=.04). Vaccination with a booster shot was associated with a protective effect on chest infection compared with the unvaccinated (CT-SS median 5 (IQR 0-11), CT-SS median 11 (IQR 7.5-14), respectively; p = .03). The Delta variant was associated with a higher odds ratio of severe disease (OR 4.6, 95%CI: 1.2, 26, p=.01) and critical care admission (OR 7.0, 95%CI: 1.5, 66, p=.004) than the Omicron variant. Conclusion The SARS-COV-2 Omicron variant was associated with fewer and less severe changes on chest CT compared with the Delta variant. Patients with Omicron had greater frequency of bronchial wall thickening but lower clinical severity and improved hospital outcomes than those with Delta.
ABSTRACT
The global COVID-19 crisis exposed the critical need for a highly qualified public health workforce. This qualitative research aimed to examine public health workforce competencies needed to face COVID-19 challenges and identify the gaps between training programs and the competency demands of real-world disasters and pandemics. Through a sample of thirty-one participant qualitative interviews, we examined the perspectives of diverse stakeholders from lead public health organizations in Israel. Grounded Theory was used to analyze the data. Six themes emerged from the content analysis: public health workforce's low professional status and the uncertain future of the public health workforce; links between the community and Higher Education institutions; the centrality of communication competencies; need to improve health promotion; the role of leadership, management, and partnership, and innovation in public health coherence. Increasing the attractiveness of the profession, professional and financial support, and improving the working conditions to ensure a sustainable and resilient PH system were deemed necessary. This paper describes and cultivates new knowledge and leadership skills among public health professionals, and lays the groundwork for future public health leadership preparedness programs.

ABSTRACT
Health services quality and sustainability rely mainly on a qualified workforce. Adequately trained public health personnel protect and promote health, avert health disparities, and allow rapid response to health emergencies. Evaluations of the healthcare workforce typically focus on physicians and nurses in curative medical venues. Few have evaluated public health workforce capacity building or sought to identify gaps between the academic training of public health employees and the needs of the healthcare organizations in which they are employed. This project report describes the conceptual framework of "Sharing European Educational Experience in Public Health for Israel (SEEEPHI): harmonization, employability, leadership, and outreach"-a multinational Erasmus+ Capacity Building in Higher Education funded project. By sharing European educational experience and knowledge, the project aims to enhance professionalism and strengthen leadership aspects of the public health workforce in Israel to meet the needs of employers and the country. The project's work packages, each jointly led by an Israeli and European institution, include field qualification analysis, mapping public health academic training programs, workforce adaptation, and building leadership capacity. In the era of global health changes, it is crucial to assess the capacity building of a well-qualified and competent workforce that enables providing good health services, reaching out to minorities, preventing health inequalities, and confronting emerging health challenges. We anticipate that the methods developed and the lessons learned within the Israeli context will be adaptable and adoptable by other countries through local and cultural adjustments.

OBJECTIVE: The chest radiograph (CXR) is the predominant imaging investigation being used to triage patients prior to either performing a SARS-CoV-2 polymerase chain reaction (PCR) test or a diagnostic CT scan, but there are limited studies that assess the diagnostic accuracy of CXRs in COVID-19.To determine the accuracy of CXR diagnosis of COVID-19 compared with PCR in patients presenting with a clinical suspicion of COVID-19. METHODS AND MATERIALS: The CXR reports of 569 consecutive patients with a clinical suspicion of COVID-19 were reviewed, blinded to the PCR result and classified into the following categories: normal, indeterminate for COVID-19, classic/probable COVID-19, non-COVID-19 pathology, and not specified. Severity reporting and reporter expertise were documented. The subset of this cohort that had CXR and PCR within 3 days of each other were included for further analysis for diagnostic accuracy. RESULTS: Classic/probable COVID-19 was reported in 29% (166/569) of the initial cohort. 67% (382/569) had PCR tests. 344 patients had CXR and PCR within 3 days of each other. Compared to PCR as the reference test, initial CXR had a 61% sensitivity and 76% specificity in the diagnosis of COVID-19. CONCLUSION: Initial CXR is useful as a triage tool with a sensitivity of 61% and specificity of 76% in the diagnosis of COVID-19 in a hospital setting. ADVANCES IN KNOWLEDGE: .Diagnostic accuracy does not differ significantly between specialist thoracic radiologists and general radiologists including trainees following training.There was a 40% prevalence of PCR positive disease in the cohort of patients (n = 344) having CXR and PCR within 3 days of each other.Classic/probable COVID-19 was reported in 29% of total cohort of patients presenting with clinical suspicion of COVID-19 (n = 569).Initial CXR is useful as a triage tool with a sensitivity of 61% and specificity of 76% in the diagnosis of COVID-19 in a hospital setting.
ABSTRACT
During the COVID-19 pandemic, chest CT is frequently used to help with the diagnosis. The classic CT patterns of COVID-19 pneumonia are well-published and recognised among radiologists. However, when there are pre-existing conditions particularly in the elderly population that could mask or result in similar patterns of disease, then the diagnosis is more difficult. This imaging essay highlights the commonly encountered situations including patients with heart failure, other possible infections particularly in the immunodeficient, and when there is trauma to the thorax. We illustrate imaging clues available to the radiologist to either make the diagnosis or at least reduce the differential diagnosis.
