Filter by:High risk human papillomavirus (hr-HPV) persistent infection is a high risk factor for cervical cancer. 85% to 90% of hr-HPV infections have the ability to clear on their own, while 10% to 15% of HPV persists further will lead to the development of high-grade intraepithelial lesions (HSIL) and even to invasive cervical cancer. Long-term follow-up results for persistent hr-HPV infection showed that cervical HSIL mostly occurred after 5-7 years of persistent hr-HPV infection, among which the risk of HPV16 and 18 was the highest, followed by HPV31 and 33. The role of the vaginal microbiome (CVM) in persistent hr-HPV infection has been increasingly valued, and women with persistent HPV infection that progresses to HSIL have a more unstable vaginal microenvironment. The previous study found that Lactobacillus vaginalis may contribute to HPV clearance by improving the vaginal microenvironment. In addition, previous studies have found that estrogen-like Chinese medicine could increase glycogen, improve mucosal estrogen levels, increase lactobacillus content, and promote HPV clearance. It is a challenge to make clinical management on when and how to intervene among hr-HPV persistent infection but whose pathology does not suggest HSIL. This study intends to analyze the correlation between the duration of HPV infection and the current vaginal microbiome, HPV load and PAX1 methylation in people with persistent HPV infection at different ages, and observe the changes of the above indicators after the administration of drugs to improve the vaginal microenvironment, which is helpful for preventing HPV persistent infection and developing into true precancerous lesions. It has the clinical and practical value of "preparing for a rainy day".
We are using a tool called QtNGS to measure the abundance of local pathogens in patients with ventilator-associated lower respiratory tract infections. We hypothesize that changes in pathogen abundance before and after treatment are related to patient outcomes. This study aims to evaluate the effectiveness of the tool by analyzing the changes in pathogen abundance and exploring the relationship between these changes and clinical outcomes.
Large numbers of micro-organisms (especially bacteria) live in and on human bodies and have a very important function for the health. These microorganisms are called 'the microbiota'. They aid in the digestion of food, ensure the production of certain vitamins, and are very important for the development and regulation of the immune system. In many diseases (including Crohn's disease, arthritis, obesity, diabetes and cancer), a disruption of microbial composition is observed. There are indications that a disruption of the microbiome can contribute to the development of inflammatory diseases and cancer, but the underlying processes are not sufficiently understood. To understand the mechanisms underlying these disease processes, fundamental research is conducted at Ghent University. Stool, skin, oral and vaginal samples from various origins are examined, e.g. from people from indigenous tribes with a traditional lifestyle. It is important that these samples can be compared with microbiome samples from healthy Western (West-European) controls. In this study, the investigators want to build up a collection of samples from healthy donors between the ages of 2 and 70, with the exception of vaginal samples collected from women between the ages of 18 and 45. The samples will form the basis for further fundamental and functional research into microbiota-host interactions at Ghent University.
The objective of this study is to investigate "clinically" the effectiveness of Boswellia based intracanal medication compared to the commonly used intracanal medicaments (calcium hydroxide Ca(OH)2 and Ledermix) on the levels of bacteria and inflammatory cytokines in root canals and periradicular tissues of teeth with apical periodontitis.
Heart failure is a major cause of mortality and morbidity in children. Heart transplantation can significantly improve the prognosis of patients with severe heart failure, but access is limited by a shortage of transplants. Long-term mechanical circulatory support is a major advance in the management of heart failure and can provide haemodynamic support while awaiting myocardial recovery or heart transplantation. The Berlin Heart (BH) EXCOR is the only long-term support system available for children. Despite technical and medical advances in circulatory support, infection is a common complication and a major cause of morbidity and mortality in patients on BH. There are few studies on the management of infection with mechanical support. Current ISHLT (International Society for Heart and Lung Transplantation) recommendations are based on expert opinion and observational studies. Some experts recommend anti-infective therapy until transplantation for specific support infections or for support-associated infections with persistent bacteraemia.

In this study we aim to characterize SARS CoV-2 strain specific immune response (SARS-CoV-2 Spike IgG) in health care workers and general populations at the Jimma Medical Center and the St. Paul Hospital in Addis Ababa in association to clinical immune protection and Covid-19 disease. Participants, stratified by SARS-CoV-2 infection and vaccination status, will be followed at 3-month intervals for a maximum of 2 years. Prevalence, incidence, and dynamics of SARS-CoV-2 specific antibodies as well as clinical assessments especially related to COVID-19 breakthrough disease in previously exposed/vaccinated participants will be performed. From a subset of selected participant blood sample, more in depth immunological analysis will be performed that include virus culture-based neutralization assays, antibody avidity assays, SARS-CoV-2 specific antibody epitope recognition using peptide arrays, and T-cell immunity assays (IGRA). We also plan to analyze and model cost-effectiveness considerations related to adapted COVID-19 vaccine strategies, specifically if SARS-CoV-2 the costs for routine sero-diagnosis in high SARS-CoV-2 prevalent population prior to vaccination will impact the decision to vaccinate (no vaccination for low-risk populations or reduced vaccine dosing) and is cost-efficient. The study is largely exploratory, providing deeper insights in SARS-CoV-2 specific immune responses and interaction with SARS-CoV-2 viral variants.
The objective of this study is to collect ultrasound signal information and visual otoscopic images with an engineering prototype device for children scheduled for tympanostomy tube surgery for the purpose of algorithm development.
This study proves that the hygiene education given to pregnant women diagnosed with tract infection by explaining what they have learned increases the duration of genital health, thus ensuring the positive health development of women and protecting and improving their health. At the same time, it is aimed to inform the professional "tell what you have learned" method and to guide the practices of those working in the field of health. The research will be conducted in a randomized control design with a pretest-posttest control group. The population of the research will consist of pregnant women who were followed up in the relevant hospital and who met the inclusion criteria on the dates the research was conducted. The number of samples for the study was determined as 70 participants, 35 in each group. While hygiene training will be given to the intervention group using the tell-what-you-learned method, no training will be given to the control group. Personal Information Form and Genital Hygiene Behavior Scale will be used as data collection tools in the research. Data will be collected at the first encounter, day 7, day 21, and day 30. In evaluating the data, the suitability of the variables to normal distribution will be examined using visual analytical methods. When comparing application results within and between groups, parametric or nonparametric tests will be used depending on whether they show a normal distribution or not, and t test or Mann-Withney U Test will be used to compare the difference between two groups. Wilcoxon test will be used to analyze pre- and post-intervention results within the same group. Statistical significance level will be accepted as p<0.05. When the literature is examined, there are studies on different health education plans for women diagnosed with urinary tract infection during pregnancy, but since there is no research on the tell-what-you-learned method, it is an original study, and at the same time, the previous knowledge levels of pregnant women diagnosed with UTI were learned and the effect of the education given on their behavior was examined. It is thought that this teaching method will contribute positively to the knowledge level and behavior of women.
