Stories for Change: Digital Storytelling Intervention for Diabetes Self-Management in the COVID-19...
Type2 DiabetesHispanic adults are twice as likely to have type 2 diabetes mellitus (T2D) and 1.5 times more likely to die from the disease than non-Hispanic whites. These disparities are mediated, in part, by less healthful levels of physical activity, dietary quality, medication adherence, and self-monitoring of blood glucose than non-Hispanic whites. Innovative approaches that arise from affected communities are needed to address these health disparities. Community-based participatory research (CBPR) has been successful in targeting health issues among Hispanic and immigrant populations; CBPR is an effective approach for addressing health behaviors in a sociocultural context. In 2004, the research team developed a CBPR partnership between immigrant communities and academic institutions called Rochester Healthy Community Partnership (RHCP) Storytelling or narrative-based interventions are designed to incorporate culture-centric health messaging to promote behavior change among vulnerable populations. Digital storytelling interventions are narrative-based videos elicited through a CBPR approach to surface the authentic voices of individuals overcoming obstacles toward engaging in health promoting behaviors to shape positive health behaviors of viewers through influences on attitudes and beliefs. RHCP partners from Hispanic communities identified T2D as a priority area for intervention, and have co-created each of the formative phases leading up to this proposal. Narrative theory and social cognitive theory formed the conceptual basis for intervention development. The study team conducted surveys and focus groups to derive the approach and personnel for building an authentic intervention that was created in a digital storytelling workshop where stories about diabetes self-management were captured, recorded, and edited to derive the final intervention products in video forma. The respective digital storytelling videos were pilot tested with 25 patients across healthcare institutions in Minnesota and Arizona. The intervention was rated as highly acceptable, culturally relevant, and perceived as efficacious for motivating behavioral change. The overall objective of this project is therefore to assess the efficacy of a digital storytelling intervention derived through a CBPR approach on self-management of T2D among Hispanic adults during a pandemic.

Effects of COVID-19 in Chronic Pain
Chronic PainCovid19The aim of this study is to evaluate the effects of the COVID-19 pandemic on pain, stress, sleep and quality of life in patients with chronic musculoskeletal pain and the relationships between them. In this cross-sectional study, 100 volunteer patients aged 18-65 years with chronic (longer than 3 months) musculoskeletal pain were included. Age, gender, body-mass index (BMI) and systemic diseases of the participants were recorded as demographic data. Data were collected regarding the area of the body where pain is most dominant in the musculoskeletal system and how long the pain has been in these area, whether there is routine use of analgesics before and after the pandemic and the amount if any, whether the person or the person's relatives have a history of COVID-19, whether exercising regularly before and after the pandemic. Afterwards, the participants were asked to evaluate their general pain severity and global well-being assesment with the visual analog scale (VAS) in the pre-pandemic period and in the last month. For pain severity, the patients marked their pain severity on a line of 10 centimeters (cm) with the starting point (0) expressing no pain, and the end point (10) expressing the most severe pain experienced in life; for patient's global assesment the patients marked their global assesment on a line of 10 centimeters (cm) with the starting point (0) expressing very good, and the end point (10) expressing very bad. The distance between the point marked by the patient and the starting point was measured. The higher the measured value meant the greater the severity of the patient's pain and the worse the patient's global assessment [11]. Subsequently, the patients were asked to answer questions on the Perceived Stress Scale (PSS), Pittsburgh Sleep Quality Index (PSQI) and Nottingham Health Profile (NHP) scales.

Retrospective Evaluation of Lung Pathology in Subjects With COVID-19
Covid19Non-interventional, retrospective, multi-center, follow-up study evaluating the effect of C21 on lung pathology in subjects previously hospitalised with COVID-19 and enrolled in the VP-C21-006 trial.

Detection of SARS-CoV-2 in Nasopharyngeal Swabs by Using Multi-Spectral Screening System
Covid19The aim of this research is to use the Multi-Spectral method to measure the biomolecular fingerprint of the virus directly instead of the virus's RNA (RT-PCR) or the body's immune response (antibody) measurement methods to diagnose the SARS-COV-2 virus, thereby determining whether COVID-19 can be diagnosed faster, cheaper and without requiring a medical laboratory environment.

Micronutrient Status Involved in Immunity in Elderly Patients With COVID-19
Covid19During the ongoing COVID-19 pandemic, age was clearly the major factor of mortality. Increasing age was strongly associated with this risk, with the upper 80 years age group having more than 12-fold increased risk compared with those aged 50-59 years. Male gender was also associated with a doubling of risk. The elderly subject is particularly exposed to global denutrition with risk of micronutrients deficiencies such as vitamins and trace elements. Those deficits expose to lower immunity. In addition, viral infection as COVID-19 can also worsen these deficits. In general, low levels or intakes of micronutrients such as Zn, Se and vitamin A have been associated with adverse clinical outcomes during viral infections. This notion has been confirmed in a recent review proposing that besides vitamins A and D also B vitamins, vitamin C, omega-3 polyunsaturated fatty acids, as well as selenium, zinc and iron should be considered in the assessment of micronutrients in COVID-19 patients. In this context, the MicroCovAging study will evaluate copper, zinc and selenium, vitamin A, D and E status in elderly subjects affected by COVID- 19 and to correlate this status with prognosis of this disease.

Negative Pressure Therapy, Minimally Invasive and Accessible Technique in the Treatment of Massive...
Subcutaneous EmphysemaCovid19Background Numerous surgicals treatments have been described for the massive subcutaneous emphysema; however, some of these techniques cannot be carried out in a critical care unit and they are related with high morbidity and exposure in positive SARS COV-2 patients. More effective, less invasive and isolated procedures should be implemented. Technique Negative pressure therapy (NPT) that can allow effective solving of massive subcutaneous emphysema in a short period (5 days) with a minimally invasive approach at the bedside in Covid-19 or non infected critical patients. Conclusion NPT is an effective and low invasive strategy for the management of EES in critical patients with high risk of mortality.

Multimodal IMAgery Characterization of Cardiac Damage and Severity After COVID-19 Infection
COVID-19 Virus DiseaseCardiac ComplicationCoronavirus Disease 2019 (COVID-19) is an infection caused by Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2), which affects multiple organ system particularly the lung and heart. Indeed, SARS CoV-2 has various cardiac manifestations which are associated with higher mortality and morbidity. Cardiac involvement, based on elevated levels of myocardial enzymes, have been described in 20 to 30% of COVID-19 infection. However, the physiopathological mechanisms of myocardial injury remains unclear. Main hypothesis include inflammation and cytokine storm, hypercoagulability and vascular thrombosis, inflammation or stress leading to coronary plaque rupture (type I myocardial infarction), supply-demand mismatch and hypoxemia resulting in myocardial damage (type II myocardial infarction) ... Two patterns can be identified : ischemic or non-ischemic pattern including myocarditis, stress induced cardiomyopathy, thrombo-embolic disease. However, the consequences of myocardial damage after confirmed COVID-19 infection are unknown at medium to long term prognosis. Data are needed to identify myocardial damage and to guide effective therapies and follow-up (use of ACE inhibitor, beta-blockers, steroids...? ) In this study, the investigators proposed to collect multimodal cardiac imaging including MRI (Magnetic Resonance Imaging) and TTE (Transthoracic echocardiogram) in order to identify and characterize cardiac injury as ischemic or non-ischemic pattern, to better assess risk stratification and to guide effective therapies if necessary.

An Effectiveness Study of the Sinovac's Adsorbed COVID-19 (Inactivated) Vaccine
Covid19This is a stepped-wedge cluster randomized trial to assess effectiveness of Sinovac's Adsorbed COVID-19 (Inactivated) vaccine. Residents in the urban area of a municipality are eligible to participate. The city was divided in clusters and those cluster were grouped to determine the offer of vaccination in four steps. The vaccine will be offered to adults (18 years old and above) according to the location of their homes in a cluster. The vaccine schedule is two doses with four-weeks interval. Baseline samples to determine previous immunity will be collected before vaccination. Cases of COVID-19 reported in the city will be recorded according to the WHO clinical progression scale. Comparison of periods before and after vaccination and relation to immunization coverage will be considered for the assessment of effectiveness in the clusters and groups of clusters.
