Active clinical trials for "Infections"

The purpose of this study is to assess the risk of congenital cytomegalovirus (cCMV) infection in newborns born to seropositive women.

Patients with neurological or neuromuscular diseases may need a long-term tracheostomy to improve their respiratory function. Bacterial flora and bacterial drug resistance in the respiratory tract have never been studied until then for this type of patient in spite of their frequent hospital stay, their regular exposition to antibiotics and their susceptibility to swallowing disorders due to their pathology. This study is based on a single tracheal aspirate within the 48 first hours of the patient stay for a ventilation check up beside any infectious context to describe the basal bacterial respiratory flora.

The purpose of this study is to identify bacterial and/or clinical features involved in the pathogenesis of Staphylococcus aureus implant-associated infections (IAI). Materials & methods: In total, 57 IAI S. aureus and 31 nasal carriage (NC) S. aureus isolates were studied. Staphylococcus aureus genetic background was obtained by microarray analysis. Multilocus sequence typing was performed to determine clonal complexes (CC). Biofilm production was investigated by resazurin and crystal violet methods

Outbreaks of emerging and re-remerging infectious diseases are frequently reported internationally in recent years, mainly due to global climate change, close human-livestock contact in developing countries, and globalization. Thus prevention, monitoring and control of infectious diseases are in urgent need to protect public health. High exposure risk to various infectious agents in health care facilities is of special concern, especially to airborne and droplet-borne respiratory diseases. To protect the health of public and health care workers the investigators will conduct a study to monitor indoor air quality and essential infectious aerosols in hospital(s). A questionnaire survey will be used to evaluate the relationships between employees' health and measured indoor environmental factors. The investigators will also examine whether the current indoor air quality recommendation of their country can reasonably reduce the risk of hospital infection. In addition, simple infectious aerosol indices will be established for future environmental management and monitoring in health care facilities.

RESTORE study:Thailand is a prospective observational study of HIV-1-infected patients who are either treatment naïve or who have been off anti-retroviral therapy for a ≥12 months, who have a CD4+ T cell count less than or equal to 350 cells/µL and who have been deemed by their treating physician that commencement of combination antiretroviral therapy (cART), which is expected to reduce plasma HIV RNA by ≥1log10 copies/mL, is necessary. The primary intent of this protocol is to prospectively establish a cohort of patients from whom clinical data and peripheral blood samples (serum, plasma and peripheral blood mononuclear cells) can be stored for substudies examining reconstitution of the immune system and its relationship to disease outcomes.

The purpose of the Study is to investigate the prevalence of Helicobacter Pylori infection among the HIV/AIDS group. The study will screen the patients who were confirmed HIV/AIDS in Kaohsiung Medical University Hospital and collect the cases who were suspicious of Helicobacter Pylori infection.

Kaohsiung Medical University Chung-Ho Memorial Hospital will provide a long-term free medical service in Indian Tibetans since July 2010. The investigators plan to investigate metabolic syndromes and HIV infection in Indian Tibetan community. The investigators will survey the prevalence and risk factors by means of HIV quick test and questionnaires. Since there is lacking of prevalence survey for metabolic syndrome and HIV infection in Tibetan colony of India, the investigiators will carry out this survey under the support and assistance of Department of Health of Central Tibetan Government.

Estimate the rate of occurrence of Invasive Fungal Infections (IFIs) in patients with acute leukemia for the first 6 months of chemotherapy (that usually correspond to four courses of chemotherapy), and hematopoietic stem cells transplantation.

The proposed study is a substudy of ATN 106 and a cross sectional study intended to be conducted at each of the AMTUs newly participating in ATN III. The intent is to enroll all youth with behaviorally-acquired HIV who have enrolled in ATN 106. The study involves a review of the subjects' medical chart and a collection of an oral rinse sample.

Objective was to understand the dynamics of Chlamydia trachomatis (Ct) detection by nucleic acid amplification testing (NAAT) after treatment and consequences for test-of-cure practice.
