This cross-sectional study will screen out hepatitis D virus-infected patients in HBsAg-positive people. Observe and describe the prevalence of hepatitis D infection among HBsAg positive people. The provinces of China are divided into 5 geographical areas (North, South, East, West and Central) to recruit patients according to the population density of each area. After statistical calculation, the total number of population needed is 3808.
Hearing loss can be the result of chronic ear infections. The role of bacteria of the genus Achromobacter is not known in these conditions. An epidemiological study including a large number of patients is needed to compare the prevalence of these bacteria in sick and healthy subjects, and to highlight the characteristics of the strains and the factors favouring their emergence.
The pandemic of a new coronavirus SARS-COV-2, which causes COVID-19 disease, has spread rapidly and is a major public health challenge. While the focus is primarily on containing the number of cases and finding alternative therapies, information is still lacking to elucidate the dynamics of viral circulation and to understand the distribution of the infection in the population. The cases reported in Argentina and worldwide could plausibly represent only a small proportion of the number of asymptomatic or poorly symptomatic cases that exist in society. However, the magnitude of this dissociation between symptomatic cases and asymptomatic persons is unknown. Knowing this information is of strategic importance as it will allow the estimation of a community prevalence and the evaluation of the best containment strategy. In fact, although all social distancing measures are now indispensable, the feasibility of prolonging the measure over time is a complex issue and in any case will require population-based information. The best way to approach the estimation of a true population prevalence is to take representative samples from the population and test them periodically. These experiences were carried out in other contexts showing heterogeneous results within the community studied. In Spain, for example, the range of antibodies present in the population varied from 1.1% to 14.2%, also showing that an important part of the population had had contact with the virus without symptoms. Studies in Switzerland and the United States also show similar findings. However, these estimates are not automatically transferable to other settings. The city of Buenos Aires has a particular demographic composition with an important group of the population living in shantytowns (it is estimated that between 7% and 10% of the population lives in shantytowns) and with much heterogeneity among the different communes of the city. In the villas, the incidence rates of COVID-19 infection differ significantly from those present in the group "outside the village". However, there is also an important difference in the incidence rates by commune, even without considering the villas. Thus, it is important to know the sero-epidemiology of antibodies against SARS-COV2 in a representative sample of the city of Buenos Aires. For this purpose, a nationally produced test (COVIDAR IgG) developed by professionals from CONICET and Instituto Leloir will be used. The aim of this initiative is to estimate the true dimension of the COVID-19 epidemic in the City of Buenos Aires, by studying the immunological status of the Buenos Aires population in relation to SARS-Cov2, as well as to observe the evolution of the infection among the population, since this information is essential to guide future public health measures related to the control of COVID-19. To achieve this objective, a comprehensive sero-epidemiological study will be carried out to provide estimates of past SARS-Cov2 infection with sufficient precision to be representative of the sero-epidemiological status of the Buenos Aires city population.
There is a pandemic in the world by COVID-19. Currently, the pharmacological curative or prophylactic treatments for this infection are not known. Recent studies have suggested that Hydroxy-Chloroquine could be effective in vitro and in vivo against COVID-19. The main objective of this study is to assess in patients with autoimmune disease treated with long course Hydroxy-Chloroquine initiated before the pandemic COVID-19 had an independent protective effect on the risk or the severity of infection with COVID-19.
The clinical study is designed to evaluate the safety, tolerability and pharmacokinetics of inhaled nanoparticle nanoparticle formulation of Remdesivir (GS-5734) alone and in combination with NA-831 in 48 healthy volunteers.
To detect microbial infection and AMR associated with COVID 19 infection. To correlate risk factors of COVID 19 patients with microbial infections and their effects on disease.
This study is intended to address the association between vitamin D status and seroconversion to SARS-CoV-2 in healthy young adults. The primary aim of the study is to determine the rates of 'silent' seroconversion rates, consistent with asymptomatic transmission of SARS-CoV-2, in a young healthy adult population with a wide spread of vitamin D concentrations. The secondary aims of this study are to explore: 1. Any effect of vitamin D status on symptomatic illness. 2. The background 'point' prevalence and subsequent rate of increase in seropositivity for SARS-CoV-2 in healthy young adults. 3. The individual reductions in seropositivity to SARS-CoV-2 over time, and changes in seropositivity in a defined young adult population over time. 4. Where salivary Immunoglobulin A (IgA) may be used to provide an alternative/ complementary serological method 5. The effect (if any) of vitamin D supplementation on seroconversion rates stratified by: i) level of baseline vitamin D 'deficiency/ insufficiency/ sufficiency' status; ii) extent of BMI-defined normal/overweight/obesity cut-offs and iii) gender.
The dysfunction of wound healing in diabetes involves multiple healing processes by diminished inflammatory responses and delayed deposition of matrix components, wound remodeling, and closure. Furthermore, hyperglycemia increases the infection susceptibility of wounds. In Taiwan, we have data demonstrating the nutrition status associated the outcome of diabetic foot ulcer (DFU) acute treatment and value of serum arginine level (in preliminary metabolomics study) to predict one-year healing of DFUs. The arginine has the beneficial effects on wound healing by the action of its metabolites, including vasodilatation, bactericide, growth factors recruitment and collage formation. Nevertheless, its supplement and mechanism in patients with diabetes is still remains unproven. This study aims at (1) defining the effects of arginine supplement, on top of the traditional treatment and risk reduction, on healing outcomes of patients with DFUs, (2) studying the modes of action of arginine supplements in diabetes, and (3) verifying the metabolomics factors and their association with wound healing prospects in patients with DFUs. A total of 120 patients with chronic diabetic foot ulcer will be enrolled and survey in 3 years. Along with standard of care, patients will receive, in a randomized fashion, either arginine (treatment group) or whey protein (control group) 5 g per day supplement for 4 weeks. The wound status will be collected with features in wound size, tissue perfusion, and infection status before and after treatment. Nutritional surveys, nitrogen balance as well as various molecular studies such as metabolomics analysis and neutrophil-to-lymphocyte ratio will be performed to study the association between the molecules of nutrients and the healing
The purpose of this study was to explore the relationship between the transmission of respiratory diseases and the correct wearing of masks, as well as the factors affecting the correct wearing of masks. The research is beneficial to the prevention of respiratory diseases and moves the barrier of prevention and control forward. It is of great significance to COVID-19 's practical prevention and control.
