COVID-19-Related Mortality amongst Physicians in Italy: Trend Pre- and Post-SARS-CoV-2 Vaccination Campaign

Globally, there has been a high burden of COVID-19-related mortality amongst physicians and other healthcare workers during the ongoing SARS-CoV-2 pandemic. Fortunately, anti-COVID-19 vaccination campaigns have helped to protect frontline workers and reduce COVID-19-related mortality amongst this occupational group. We analyzed COVID-19-related mortality data for doctors in Italy and compared the crude mortality rate between March–May 2020 (i.e., the beginning of the pandemic in Italy, with the highest rates of COVID-19-related deaths) and the same time period in March–May 2021 (high vaccination coverage amongst Italian physicians). The mortality rate was 12 times higher in March–May 2020 compared to the same time period after the start of the Italian vaccination campaign. Moreover, there was a strong inverse correlation between the number of deaths and the cumulative number of vaccine doses administered in the Italian population. Although non-pharmaceutical interventions, virus evolution and environmental factors probably had an effect, our analysis clearly supports the hypothesis that the vaccination campaign helped to protect Italian physicians and reduce COVID-19-related mortality. The latest available death trends from September to October 2021 for both physicians and the general population are also in favor of the need for the third vaccine dose, currently underway for the majority of the population at risk

DESIGN: A modified Delphi study was performed to reach consensus on priority areas and barriers to the development of the Chronic Care Model in the health system of Abu Dhabi. Individual wireless audience response devices (keypads) linked to a computer were used to reduce 28 priorities and 20 barriers to the top five during three iterative rounds over three consecutive days. SETTING: Chronic care services for patients with diabetes, cardiovascular diseases and cancer, in both private and publicly funded healthcare services in the emirate of Abu Dhabi. PARTICIPANTS: A purposive sample of 20 health systems' experts were recruited. They were front-line healthcare workers from the public and private sector working in the delivery of care for patients with diabetes, cardiovascular diseases and cancer. RESULTS: The 'overall organizational leadership in chronic illness care' was ranked as the most important priority to address (26.3%) and 'patient compliance' was ranked as the most important barrier (36.8%) to the development of the Chronic Care Model. CONCLUSIONS: This study has identified the current priorities and barriers to improving chronic care within Abu Dhabi's healthcare system. Our paper addresses the UAE's 2021 Agenda of achieving a world-class healthcare system, and findings may help inform strategic changes required to achieve this mission.publishersversionpublishe

Modeling, Simulation and Control of Flat Panel Solar Collectors with Thermal Storage for Heating and Cooling Applications

AbstractThe focus of the present study is on the transient modeling of components in a solar system, controls, and heating and cooling loads. The system consists of solar flat plates and a thermal storage tank, which could provide a portion of heating requirements of a social enterprise building located in Winnipeg, Manitoba, Canada. This solar system and a natural gas hot water heater may replace the low efficiency boiler that supplies low quality steam for heat throughout the building using radiators. Results of the simulation performed in Simulink supports the proper selection of solar system components and controls that will be optimized for the climatic attributes of Winnipeg

Occupational Exposure to Solar Radiation and the Eye: A Call to Implement Health Surveillance of Outdoor Workers

Globally, hundreds of millions of outdoor workers are exposed to solar radiation (SR) for most of their work. Such occupational exposure is known to induce various adverse health effects on the eyes, mainly related to its ultraviolet (UV) component. The present work is a call to action to raise awareness of the need for health surveillance to prevent chronic ocular diseases in outdoor workers. Photo-chemical chronic damage can induce pterygium at the eye's outer layer and cataracts in the lens. Considering carcinogenic effects, rare squamous-cell tumors of the cornea and/or the conjunctiva and ocular melanomas are associated with UV radiation exposure. Solar UV-related eye diseases should be considered "occupational diseases" when workers have sufficient exposure. Still, they are often not recognized and/ or frequently not reported to the national compensation authorities. Therefore, to prevent the burden of these work -related eye pathologies, an adequate risk assessment with identification of appropriate preventive measures and a provision of periodic health surveillance to the exposed workers, particularly those at higher risk of exposure or with individual susceptibility, should be urgently implemented

Incidence of Gestational Diabetes Mellitus in the United Arab Emirates; Comparison of Six Diagnostic Criteria: The Mutaba’ah Study

BACKGROUND: For more than half a century, there has been much research and controversies on how to accurately screen for and diagnose gestational diabetes mellitus (GDM). There is a paucity of updated research among the Emirati population in the United Arab Emirates (UAE). The lack of a uniform GDM diagnostic criteria results in the inability to accurately combine or compare the disease burden worldwide and locally. This study aimed to compare the incidence of GDM in the Emirati population using six diagnostic criteria for GDM. METHODS: The Mutaba’ah study is the largest multi-center mother and child cohort study in the UAE with an 18-year follow-up. We included singleton pregnancies from the Mutaba’ah cohort screened with the oral glucose tolerance test (OGTT) at 24–32 weeks from May 2017 to March 2021. We excluded patients with known diabetes and with newly diagnosed diabetes. GDM cumulative incidence was determined using the six specified criteria. GDM risk factors were compared using chi-square and t-tests. Agreements among the six criteria were assessed using kappa statistics. RESULTS: A total of 2,546 women were included with a mean age of 30.5 ± 6.0 years. Mean gravidity was 3.5 ± 2.1, and mean body mass index (BMI) at booking was 27.7 ± 5.6 kg/m(2). GDM incidence as diagnosed by any of the six criteria collectively was 27.1%. It ranged from 8.4% according to the EASD 1996 criteria to 21.5% according to the NICE 2015 criteria. The two most inclusive criteria were the NICE 2015 and the IADPSG criteria with GDM incidence rates of 21.5% (95% CI: 19.9, 23.1) and 21.3% (95% CI: 19.8, 23.0), respectively. Agreement between the two criteria was moderate (k = 0.66; p < 0.001). The least inclusive was the EASD 1996 criteria [8.4% (95% CI: 7.3, 9.6)]. The locally recommended IADPSG/WHO 2013 criteria had weak to moderate agreement with the other criteria, with Cohen’s kappa coefficient ranging from (k = 0.51; p < 0.001) to (k = 0.71; p < 0.001). Most of the GDM risk factors assessed were significantly higher among those with GDM (p < 0.005) identified by all criteria. CONCLUSIONS: The findings indicate discrepancies among the diagnostic criteria in identifying GDM cases. This emphasizes the need to unify GDM diagnostic criteria in this population to provide accurate and reliable incidence estimates for healthcare planning, especially because the agreement with the recommended criteria was not optimal
