Filter by:Cervical cancer (CCU) is the fourth most common cancer in women worldwide. In Reunion island, CCU is the third leading cause of cancer in women (standardized incidence rate on the world population (TIS) in 2013 of 10.3 / 100,000) and is the eighth deadliest cancer with a rate standardized mortality of 4.8 / 100,000, almost three times higher than in mainland France where it was 1.7 / 100,000 in 2018. CCU results from infection with the human papillomavirus (HPV), which is the most common sexually transmitted viral infection. CCU prevention is mainly based on cervical smear screening and anti HPV vaccination (VHPV) which has demonstrated its effectiveness on the prevalence of HPV carriage, but also on incidence of condyloma or intermediate grade dysplasia. Since HPV is mainly transmitted sexually, it is important to vaccinate before the start of sex. In Reunion island, the HPV vaccination coverage rate is the lowest in France, estimated by Public Health France at 8.1% among girls aged 16 years in 2018, while the already low national average was established 23.7%. Thus, in view of the epidemiological situation in Reunion island (high incidence and mortality for the CCU, very low VHPV coverage rate), we thought it would be interesting to study the impact of a health promotion program sex and prevention of sexually transmitted infections (STIs) including papillomavirus-related pathologies, with a program to promote HPV vaccination among young students in middle school.
This protocol tests the safety and efficacy of a novel universal vaccine concept called "allo-priming" which is designed to protect elderly adults from progression of any type of viral infection, including possible protection against progression of the current outbreak of COVID-19 infection, and any future variants, strains, mutations of the causative SARS-CoV-2 virus as well as protection from any future currently unknown newly emergent novel viruses.
Based on findings of the interim analysis of the ACTIVATE study showing 53% decrease of the incidence of all new infections with BCG vaccination, a new trial is designed aiming to validate if BCG can protect against COVID-19 (Corona Virus Disease-19).The aim of the study is to demonstrate in a double-blind, placebo-controlled approach if vaccination of participants susceptible to COVID-19 with BCG vaccine may modulate their disease susceptibility for COVID-19. This will be validated using both clinical and immunological criteria. At the same time, a sub-study will be conducted and the mechanism of benefit from BCG vaccination by assessing its effect on vascular endothelial function and mononuclear blood cells will be studied
This observational study will describe lung ultrasound (LUS) findings over time in hospitalized patients with moderate to severe Covid-19 lung disease. Our primary aim is to investigate if lung ultrasound can identify and/or predict patients requiring mechanical ventilation. Another aim is to describe LUS findings associated with clinical findings and patient condition.
Ebola virus is one of the most dangerous human pathogens and is an emerging public health problem in sub-Saharan Africa. Ebola virus disease (EVD) first appeared in 1976. The current epidemic in the Democratic Republic of the Congo (DRC) is one of the largest and most complex ever recorded, and is not yet under control: a new death has been reported on April 10th, 2020. The epidemic was declared a public health emergency of international scope by the World Health Organization (WHO) on July 17th, 2019. Two studies are the "standard" in the assessment of the consequences of infection in survivors, in Liberia (PREVAIL) and Guinea (PostEbogui), especially in: - The observation of comparable mortality rates, even if over time there was an improvement in survival, probably linked to the improvement in the quality of care and symptomatic treatment; - And the study of the contacts of the survivors, between 4 to 10% of them had done seroconversion with regard to Ebola virus (EBOV) in an asymptomatic or pauci-symptomatic way and that this rate varied according to the degree of exposure to the risk. The DRC's experience in this area and the enormous progress made in the fight against Viral hemorrhagic fevers (VHFs), therapeutically and preventively (where much of which patients have benefited from antiviral treatment or monoclonal antibodies), the technological responses (real-time sequencing of Ebola strains in new cases, vaccination or the use of individual isolation units), show the limits of their effectiveness. A large number of questions therefore remain unanswered: - The antibody profile of the survivors, in particular the repertoire of immunoglobulin G (IgG) specific to these individuals and its correlation with survival and its evolution over time; - The impact of treatments initiated during the acute phase on these immune abnormalities; - Finally, genetic factors linked to the host could play an important role in the response to the Ebola virus. The aim of this study is to provide a better overall understanding of Ebola virus infection and its clinical, virological, and immunological consequences, of cured people and their contacts; strengthen multidisciplinary monitoring of patients after an acute phase of EVD. The results will therefore have a direct impact on the clinical management of this population and on the prevention of possible secondary contamination in the Democratic Republic of the Congo.
This randomized clinical trial will evaluate the benefit of platelet-rich plasma (PrP) in the treatment of olfactory dysfunction. PrP can be isolated from a patient's own blood and has been found in previous studies to have anti-inflammatory and pro-regenerative properties. It has been used across multiple specialties, such as Orthopedics, Facial Plastics, Dermatology, Neurology in injected form to treat a wide variety of tissues to encourage the body's inherent regenerative capacity. The investigators have completed a pilot study here evaluating it's use in olfactory loss which demonstrated safety and also suggested efficacy. Therefore, the investigators aim to assess the ability of PrP to improve olfactory function in patients with decreased sense of smell.
To ascertain globally the changes in the cytokines involved and TLRs/KIR activation in patients admitted to the hospital with a COVID-19 diagnosis, and the changes after initiation of the different therapies
Recent information appearing from different countries suggest that treatment of Coronavirus disease 2019 (COVID-19) with hydroxychloroquine or with a combination of hydroxychloroquine and azithromycin has either an indifferent effect on viral replication or substantial cardiotoxicity. This is a clinical trial aiming to prove that addition of oral clarithromycin to treatment regimen of COVID-19 is associated with early clinical improvement and attenuation of the high inflammatory burden of the host. The study will not comprise a placebo-comparator group since this is considered inappropriate in an era of a pandemic with substantial global mortality.
COVID-19 has adversely affected the healthcare system across the world. The world was not prepared for global outbreak of infectious diseases. The rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is enabling researchers worldwide to acquire a large amount of clinical data regarding coronavirus disease (COVID-19). The COVID-19 infection severely affects the respiratory system in the critical cases and results in mortalities. The affected people experience a dry cough, fever, breathing problems, diarrhea, muscle pain, and sore throat. Besides that, some of the evidence from Italy, South Korea, China, and Spain suggest that the COVID-19 cases also lose their senses of smell and taste resulting in alterations in those patients. The objective of this proposed study is to determine whether COVID-19 cases have Olfactory and gustatory dysfunctions as a hallmark indicator and can be used as diagnostic tools for the isolation of suspected people. Investigators are presenting a prospective proportional case-control study that is conducted to investigate the COVID-19 cases with anosmia and /or Ageusia in a university hospital in Riyadh, Saudi Arabia. The sample size of this case series would be 250 cases of suspected COVID-19 patients. The cases included in the study are analyzed prospectively to determine if the cases had a history of anosmia and /or Ageusia, and then tested for the alteration of these senses through a panel of standardized odors/taste strips. That is looked at statistically allowing us to confirm the proposed effectiveness of these tests as a diagnostic tool.
A total of 201 participants with chronic HCV GT4 infection were allocated into two groups. One group participants were treated with SOF plus RBV (24 weeks). The second group was treated with SOF plus SMV (12 weeks).
