Filter by:Atraumatic Restorative Treatment (ART) was proposed as a new and effective method in the 1990s to provide conservative dental treatment to the people living in economically underdeveloped countries, due to lack of dental treatment facilities. In the technique, after the carious dentin is removed by excavation with hand instruments, the powder-liquid system conventional glass ionomer cement (GIC) which does not require special devices for mixing and hardening is used as a filling material. Because of these advantages of the treatment, the usage fields of ART have been expanded considering that it can be applied in the cases that working with rotary instruments is difficult or even impossible. But only a few research has been conducted on ART in adults and it must be investigated in terms of the clinical safety of ART by the studies focused on the counts and activities of the microorganisms in carious dentin left on the cavity floor. The purpose of this study is to investigate the reliability of ART in adult individuals related to the marginal adaptation of the restorations and the microbiological changes in the left carious dentin using in vitro and in vivo methods. In the in vivo part of the study, occlusal dentin carious of 25 participants at high risk of caries were removed with hand instruments and microorganisms of the last removed carious dentin were evaluated quantitatively concerning the bacterias playing a major role in caries lesions. The restorations of the teeth were carried out using ART technique with a GIC which has been proven its effectiveness in preventing the caries progression and recurrent caries in the practice of dentistry for many years. After six months, the microbiological assessment was repeated such as baseline. Marginal adaptation and the presence of the gaps in the ART restorations on the replicas created with the impression materials at the baseline and sixth month were investigated under scanning electron microscope. At the end of the study, the teeth were restored by the conventional methods and using composite material.
This is a randomized study that sought to analyze the diagnostic accuracy of the telemedicine consultation of patients suspected of respiratory tract infections during COVID-19 pandemic in comparison with the face-to-face evaluation at the emergency department.
Ear-loop-type Korean Filter 94 masks (KF94 masks, equivalent to the N95 and FFP2) are broadly used in health care settings in Korea for the COVID-19 pandemic. However, no studies have assessed the adequacy of respiratory protection. In this prospective randomized open-label study, the investigators aimed to evaluate the fitting performance of ear-loop-type KF94 masks by the quantitative fit test according to the occupational safety and health administration (OSHA) protocol. In addition, by quantitatively comparing the "tight-fitting" method using a clip and the "general-fitting" method, the investigators tried to evaluate whether the tight-wearing method improves the fitting performance of KF94 masks.
Investigators have designed a single-center randomized controlled trial to compare chlorhexidine gluconate (CHG)-impregnated dressing and standard dressing with respect to their effects on the infection outcomes. The study was condcuted in the pediatric intensive care unit in the 18 months period.
BACKGROUND: On January 7, 2020, the Chinese authorities identified as the agent responsible for the cases of atypical pneumonia of unknown etiology a new type of virus of the Coronaviridae family that has subsequently been named SARS-CoV-2, whose genetic sequence was shared by Chinese authorities on January 12 (taxonomy ID: 2697049). On January 30, 2020, the director general of the World Health Organization (WHO), following the advice of the Emergency Committee convened in accordance with the International Health Regulations (2005), declared that the COVID-19 outbreak started in Wuhan, China in December 2019, being a public health emergency of international concern. On March 11, the WHO declared the global SARS-CoV-2 pandemic. So far, in the absence of effective vaccines or antiviral drugs, efforts have focused on identifying cases and their contacts. Both the cases and their contacts are isolated for about 14 days with the intention of minimizing the spread of this infection and avoiding an increase in the number of affected. At the time of writing this new version of the protocol, we are immersed in the second wave of the COVID-19 pandemic. The projections of the natural history of the disease and the estimates of possible infections by SARS-CoV-2, carried out at the end of the first wave, made it possible to determine the feasibility of this second wave with the onset of cold from the autumn. Given this scenario, the University of Barcelona, together with the Gerencia Territorial del Área Metropolitana Sud, has planned to carry out, a study of seroprevalence and screnning of SARS-CoV-2 in the population of Universidad de Barcelona users. The results of this study will help to make preventive decisions in the face of SARS-CoV-2 infection at the UB, in relation to its teaching and administrative activities. In addition, this cross-sectional study can serve as the base study for a future follow-up study. HYPOTHESIS: The incidence of SARS-CoV-2 infection in the group of students and workers at the University of Barcelona is similar to the incidence in the general population. MAIN OBJECTIVE: - Estimate the incidence of SARS-CoV-2 infection in the UB community. - Estimate the SARS-CoV-2 seroprevalence infection in the UB community.
The medical charts of all COVID-19 cases (n=1200) from 17 long-term care facilities in Montreal, Canada will be reviewed, to compare patients who survived to patients who did not survive. Through multilevel logistic regression, the risk of death will be estimated for institutional predictors of mortality, while controlling for individual risk factors. Individual covariates include clinical features (age, sex, Charlston comorbidity index, SMAF autonomy score, severity criteria) and medical treatments (IV fluids, anticoagulation, oxygen, regular opiates, corticosteroids). Aggregate covariates include epidemiological data (attack rates, timing of outbreak) and institutional characteristics (number of beds, air exchange per hour, presence of a dedicated COVID-19 unit at the time of outbreak, staff compliance to infection control measures, staff infection rates, understaffing, proportion of semi-private rooms, proportion of wandering wards and other special units).
This study is to obtain a comprehensive view of S. aureus adaptations in the infected human host and (i) to improve the understanding of the interface between antibiotic therapy, resistance development and virulence factor adaptation in S. aureus infected patients, and (ii) to adapt these findings into a more sustainable use of antimicrobials for therapy.
The aim of this study is to verify the quantitative and qualitative effect of Erbium dental laser therapy on microbial populations in carious lesions and to compare the laser therapy with traditional conservative therapies.
Both the endocannabinoid system and the microbiome are highly conditioned by nutrition and physical activity, and have an interdependent, bidirectional relationship. We suggest studying the interleaving between the endocannabinoidome-microbiome axis and host metabolism under the combined effect of a diet and physical activity. More specificly, we will study the link between the impact of the diet on the intestinal microbiome and the endocannabinoid reaction after intense exercise.
This study is an open-label trial in which hospitalized patients with risk factors of severe coronavirus disease 2019 [COVID-19] will be receive treatment with convalescent plasma (≤ 15 days from symptoms start).
