Filter by:The clinical courses of COVID-19 in children are reportedly mild, and may therefore readily escape diagnosis. Prolonged intestinal virus shedding has been reported in children, thus rendering the pediatric population a potentially important source of virus transmission. However, the infectious potential of SARS-CoV-2 (severe acute respiratory syndrome coronavirus type 2) excreted in the stool has remained enigmatic. The investigators hypothesize that stools carrying the virus can represent a source of infection, at least in a proportion of instances, and therefore intend to screen stools of children admitted to the hospital regardless of the indication in order to assess the frequency of intestinal virus excretion. The screening will be performed by validated RTQ-PCR (reverse transcription quantitative polymerase chain reaction) assays. In positive cases, stool extracts will be used to inoculate permissive cells (e.g. VeroE6) under BSL3 (Biosafety Level 3) conditions, and the infectious potential of the viruses will be determined. The readout will be based on the assessment of cell cytopathic effects and on the expression of subgenomic mRNA. it is expected to recruit ~100 patients for the study. Additionally, the investigators will specifically examine children admitted to the hospital because of COVID-19, and will determine the temporal correlation between viral loads in the upper respiratory tract (URT) and serial stool specimens as well as swabs from the palms and from the oral cavity using RTQ-PCR. Longitudinal studies on the infectious potential of viruses from the URT and stool will be performed using the experimental approach outlined above. For this part of the study, is is intended to recruit ~100 children. Furthermore, samples derived from >200 patients from our biorepository will be used. The insights gained from the study will greatly expand the knowledge on the epidemiological and clinical significance of SARS-CoV-2 infections in children. If stools are identified as a potential source of infection, the data will have an important impact on safety measures in specific settings such as the kindergarten.
It is known that the pretreatment with exogenous interferon blocks SARS-CoV-2 infection, but intervention is much more effective if administered prior to infection. In this study the primary aim is to investigate 28-day regime of nasal interferon gama use in healthy participants for COVID-19 and other respiratory infections prevention.
This is the first Case Studies article highlight factors determine the effectiveness of Convalescent Plasma Therapy (CPT) in Indonesia, accompanied by supporting data and images before and after the patients received the therapy. This Case Studies gives a huge contribution as CPT still on going as multicentre study and apply massively as emergency approved treatment in Indonesia.
Given the magnitude of the epidemic in Puerto Rico, congenital Zika virus infection may have devastating complications to a significant population of children, also affecting families and society at large. This proposal takes a critical first step to ensuring that children with exposure to congenital Zika virus infection receive the follow-up care they need for optimal clinical outcomes. We anticipate that lessons learned from this study may also positively impact models for adherence to early intervention services in Puerto Rico.
In this randomised controlled trial the investigators will determine whether taking iron supplements compared to placebo for 21 days alters the bacteria (microbiome) in the large intestine of non-pregnant female participants.
A multicenter, randomized, double-blind, placebo controlled comparative study to evaluate the safety, tolerability and efficacy of XC221 used at 100 mg daily and at 200 mg daily in patients with uncomplicated influenza or other acute viral upper respiratory infections (URIs) for 5 days of treatment. The primary objective of the study is to evaluate the efficacy of ХС221 at 100 mg and at 200 mg in comparison with placebo regarding its effect on the severity and duration of influenza symptoms and symptoms of other viral URIs (fever and other major signs and symptoms). The secondary objective of the study is to evaluate the safety of ХС221 at 100 mg and at 200 mg in comparison with placebo in the treatment of influenza ad other viral URIs.
This clinical trial is designed to evaluate if the periodic screening for deep venous thrombosis by ultrasound of lower extremity in patients with intensive care unit (ICU) patients with COVID 19 impacts on mortality, ICU stay and total length of stay in the hospital, along with other outcomes.
This qualitative study aims to explore lived experiences of older adults living with HIV in Hong Kong. Twenty older Chinese adults of age 50 or above will be recruited from an HIV specialist clinic providing HIV care in the public service. Qualitative, semi-structured interview will be conducted to explore risk factors contributing to life stress and adversity, and protective factors associated with resilience. The qualitative data will be delineated to propose a typology of older adults living with HIV as characterized by their unmet needs, barriers and facilitators of resilience-building.
This retrospective study will evaluate characteristics, vaccine utilization and outcomes among subjects with immunocompromising conditions that received COVID-19 vaccination.
Surgical site infections (SSI) constitute an important health concern in low and middle income countries, leading to prolonged hospital stay and increased costs. Previous studies indicate that in Africa up to 1/3 of patients undergoing surgery may be affected by a postoperative infection. The development and implementation of context-specific SSI prevention guidelines is important to reduce this complication. To deploy efficient context-specific measures, data on epidemiology and microbiology of these infections are needed. This means to adapt the prevention measures to the context-specific risk factors for surgical site infections in resource-limited settings, and to give locally adapted recommendations on antimicrobial therapy based on local resistance patterns. However, data in this respect are scarce in low and middle income countries. This present study will contribute to the needed epidemiology and microbiology data on SSI in Cameroon. It will be carried out as a prospective cohort study at the Mbouo Protestant hospital in the West Region of Cameroon. The incidence, microbial spectrum and respective antimicrobial resistance of SSI as well as the risk factors of SSI will be systematically investigated. The study will include 300 patients at the Hôpital Protestant de Mbouo (HPM) who underwent surgery and gave their informed consent for inclusion, the timeframe is 04/2021 - 11/2021. An active SSI surveillance system will be put in place for 30 postoperative days to diagnose SSI. Expected outcomes: The incidence of SSI is likely to be higher than 10%. Concerning risk factors, preoperative bodywashing and perioperative antibioprophylaxis is expected to be protective against SSI. Up to 1/3 of SSI are expected to occur after hospital discharge. For the microbial spectrum, a high proportion of Staphylococcus aureus is likely to be found. For the antimicrobial resistance no estimation can be give as data is non-existent in that region from the literature.
