Active clinical trials for "Communicable Diseases"

An open access study that will define and collect digital measures of coughing in multiple populations and public spaces using various means of audio data collection.

Web-based survey to members of 10 Spanish Associations of surgical nurses and surgeons of different specialities to know the application of preventative measures for surgical site infection.

Urinary tract infections (UTI) are an important part of infectious diseases. For some patients, those infections are recurrent and have many consequences such as altered quality of life, recurrent symptoms, antibiotics overuse… The primary purpose of this study is to estimate the proportion of patients in Puy-de-Dôme with recurrent urinary tract infections among patients with at least one UTI during 2019. The secondary purposes are : characteristics of patients with recurrent UTI, by sex ; determine predictive factors of recurrent UTI, by sex ; describe bacterial ecology of recurrent UTI and the proportion of multi-resistant bacteria.

Gastric cancer is the third most common cause of cancer-related death worldwide (1). Upper endoscopy is necessary to detect neoplastic macroscopic features at an early stage, but subtle abnormalities in the gastric mucosa are often missed or misdiagnosed (1). Helicobacter pylori (Hp) is involved in the pathogenesis of gastric diseases, such as, peptic ulcers, gastric lymphoma, and gastric cancer. Therefore, the necessity to recognize malignant gastric lesions at an early stage is imperative.

The COVID-19 pandemic of SARS CoV2 (Severe Acute Respiratory Syndrome, COVID-19) infection, which is currently evolving in France, raises many questions about the clinical and biological profile of infected hospitalized patients. If certain biological factors like troponin, BNP (Brain Natriuretic Peptid), or clinical factors like cardiovascular history or oncological history are associated with a worse prognosis, available data comes from studies in Asia for the majority, or including a limited number of patients. Patient stratification remains a major issue for patient sorting and early referral of patients.

In December 2019, Coronavirus infection (COVID-19) was identified as causing serious respiratory infection in humans. Initially COVID-19 was propagated by infected symptomatic individuals; currently the disease is disseminated by asymptomatic COVID-19 positive subjects. The prevalence of asymptomatic COVID-19 individuals is unknown. Due its physiologic immune suppression, pregnancy is a vulnerable time for severe respiratory infections including COVID-19. Limited information is available regarding the impact of COVID-19 in pregnancy and the prevalence and demographic profile of asymptomatic pregnant women. Despite reports of 15-20% positive COVID-19 tests in women admitted to Labor and Delivery, professional obstetric medical societies still recommend not prioritizing testing of patients who are asymptomatic. In the USA, COVID-19 symptomatic patients come predominantly from lower income, Black and Latino communities. No data are available on the rate and demographic distribution of asymptomatic positive COVID-19 pregnant women. To minimize the risk of inadvertent exposure asymptomatic individuals, recently our institution started COVID-19 testing in all admitted pregnant women. The investigators expect to gain knowledge on the impact of COVID-19 in pregnant women especially if asymptomatic and compare to other respiratory infections.

Perineal injury following childbirth can result in complications such as wound infection. The perineum has closely related anatomical structures including the external genital organs and the anal triangle which contains the anal sphincter muscles. Therefore as wound infection can extend and as muscles of the perineum sit in such close proximity to each other, the anal sphincter muscles could potentially be affected. This could also potentially include cases of perineal injury where the anal sphincter was not injured. However ultrasound has never been used to investigate this. Endoanal ultrasound is the gold standard diagnostic tool in the assessment of obstetric anal sphincter injury. The anal sphincter can also be visualised using multiplanar transperineal ultrasound(three/four-dimensional. Therefore both modalities could be used. However, it has been shown that transperineal ultrasound has a high positive predictive value and therefore is able to correctly identify an intact anal sphincter, but low positive predictive value; meaning poor detection of sphincter defects. Therefore, although it cannot completely substitute endoanal ultrasound (the gold standard in investigating obstetric anal sphincter injuries), it provides and adjunct/alternative for women who cannot tolerate endoanal ultrasound. The investigators plan to perform an observational study to evaluate to the natural history of perineal wound infections. Patients will be assessed weekly with endoanal ultrasound and/or transperineal ultrasound until the wound infection has resolved and the wound has clinically healed. If a bacterial wound swab has not been taken prior to recruitment or wound swab results are not available, one will be taken to detect the causative organisms. Appropriate antibiotics will then be given to cover the detected organism. Bacterial burden and will also be measured weekly using the MolecuLight i:X; a bacterial autofluorescence camera which captures the presence and load of bacteria. In wounds that have superficially dehisced; exact wound measurements including wound surface area, depth, volume and healing progress will be precisely measured using the Silhouette® 3D camera

This is part of a feasibility study to compare the predicate standard FDA cleared test for serum to a point of care test Toxoplasma ICT IgG-IgM BK produced by LD Bio Diagnostic. The specificity and sensitivity in testing serum and whole blood will be compared. This study includes 70 persons either pregnant or non pregnant. This is being done in accordance with FDA requirements for clearance of a testing device . We will use a standard FDA cleared test in all studies. The FDA has suggested that we submit a pre subQ for a 510K and dual CLIA waiver. This allows us also to determine feasibility of use of the predicate test in conjunction with the experimental test with volunteers, including men, women, and pregnant women.

The purpose of this study is to identify the epidemiological and clinical characteristics of patients diagnosed with non-cholera Vibrio infection in Western France from 2000 to 2019.

A retrospective study to determine the potential value of MDW among other biomarkers in the diagnosis of infection.
