Filter by:Tuberculosis (TB) is now the commonest cause of death in many African countries. Globally, ~35% (almost 1 in 3) of TB cases are 'missed' (remain undiagnosed or undetected). In sub-Saharan Africa, 40-50% of the TB case burden remains undiagnosed within the community. These 'missed' TB cases (at primary care level) serve as a reservoir, which severely undermines TB control. With rapid advances in the development of TB screening tests, the investigators aim to determine the pragmatic utility of computer-assisted x-ray diagnosis (CAD). Recent data suggest that CAD performs on par with experienced radiologists to identify potential TB cases, hereby reducing the frequency at which Xpert tests are requested and helps to focus limited resources on the relevant cases. In addition, the investigators aim to test nascent screening technologies for TB diagnosis such as evaluating urine-based TB screening biosignatures. The COVID-19 pandemic has ravaged African peri-urban communities where TB is also common. With the pressing need to improve screening and diagnosis of COVID-19, the investigators plan to explore the potential for urine- and blood-based COVID-19 screening assays. Symptoms of COVID-19 and TB overlap, and limited affordability, as well as the stigma associated with both diseases, severely limits testing. Data are now urgently needed about the feasibility of co-screening and testing for TB and COVID-19. The utility of such an approach, if any, has not been studied in African communities.
The emerging SARS-COV2 virus has shed a new light on the cross-talks between the immune and the hemostatic system. In this study we aim to evaluate the dynamic change in coagulation caused by the modulation of the inflammatory response by interleukin-6 antagonist as assessed by viscoelastic methods in critically ill COVID-19 patients. Furthermore we try to draw attention to possible associations between the endothelial cell injury, inflammation and coagulation.
This is a double-blind, multicentre, multinational study to evaluate the safety and collect preliminary efficacy data of Codivir drug product in 130 hospitalized adults with moderate COVID-19 symptoms. COVID-19 symptoms (fever, cough, myalgia and changes in smell or taste) onset must be within 7 days prior enrolment. Treatment will begin in the hospital, participants will be discharged according to medical decision and continue the treatment until to Day 7 at home and followed up to day 28.
This is an observational cross sectional study included 202 patients diagnosed to have COVID-19. The study was conducted at Zagazig University Isolation Hospitals from the period of March 2020 to June 2021. The study was approved by Zagazig University Ethics Committee (number 9229). A written informed consent was obtained from all participants. Inclusion criteria: The study includes laboratory confirmed COVID-19 patients (confirmed by real-time polymerase chain reaction) admitted l during the period of the study. The patients were classified into two groups, group A included mild/moderate cases, group B included severe/critical cases according to the following criteria. Severity of COVID-19 was graded as follows: mild; mild clinical symptoms, no pneumonia on lung CT; moderate: fever, cough and lung CT with pneumonia; severe: respiratory distress (respiratory rate > 30 /min, oxygen saturation (O2Sat) ≤ 93 percent at rest and/or ratio of arterial oxygen partial pressure to fractional inspired oxygen ≤300 mmHg (PaO2/FIO2); and critical: aforementioned criteria of respiratory failure receiving mechanical ventilation, shock, and/or organ failure other than lung and/or intensive care unit (ICU) hospitalization. All participants were subjected to full history taking including smoking history and comorbidity profile. Clinical symptoms including: fever, cough, dyspnea, myalgia, hemoptysis, sore throat, diarrhea, loss of smell and anorexia were recorded. Radiological assessment by initial chest x ray then CT chest as possible and appropriate. Routine laboratory investigations: Complete blood count (CBC), coagulation profile, serum biochemical tests (including renal and liver function, and electrolytes), laboratory investigation to assess severity of COVID-19: lactate dehydrogenase (LDH), myocardial enzymes (CPK-MB), serum ferritin, D dimer and arterial blood gases analysis. Patients were followed up for the need for ICU and mechanical ventilation (MV), duration till conversion, total length of stay and final outcome whether survived or died were recorded.
Studies reveal that the Covid-19 virus can be transmitted in three ways: respiratory tract, direct contact and feces. The incubation period is estimated to be 5.2 [4.1-7.0] days for the 95% confidence interval and the virus transmission coefficient (R0) baseline growth number is 2.2 [1.4-3.9]. The main signs and symptoms described in the literature are; other atypical symptoms, particularly fever (98%), cough (76%), myalgia or fatigue (44%); sputum (28%), headache (8%), hemoptysis (5%), vomiting (5%), diarrhea (3%) and shortness of breath were detected. In addition to lymphopenia, which is detected in 63% of cases, pneumonia is also present. Widely regarded as the cornerstone of pulmonary rehabilitation, exercise training is the best way to improve muscle function in COPD and other chronic respiratory diseases. After 326 patients hospitalized in the pandemic clinical services of a public hospital were randomly divided into the experimental (n=168) and control groups (n=168), the effect of the experiment on the respiratory parameters of the experiment will be monitored without any intervention in the control group, while deep breathing and coughing exercises will be applied to the experimental group. The aim of this study is to determine the effect of deep breathing and coughing exercises on respiratory parameters in patients treated for pneumonia due to COVID-19 disease.
To examine the efficacy of an 8-week exercise training program on functional, cognitive, and emotional health outcomes compared to a no treatment control condition in adults with PASC.
Multicenter, prospective, randomized controlled trial providing mobile health supported physical rehabilitation to 120 patients who have been critically ill with COVID-19 and who complete at least one exercise session.
This is a phase I, prospective, three-arm, open-label, randomized, first in human (FIH) clinical trial to assess the safety and immunogenicity of EgyVax vaccine candidate for prophylaxis of SARS-CoV-2 infection (COVID-19).
Dysfunctional breathing might participate to dyspnoea in long COVID-19. This study investigate the prognosis of patients diagnosed with dysfunctional breathing after SARS-CoV-2 infection in our center.
The world health organization declared corona virus disease (COVID19) a pandemic since march 2020. Since then the future landscape of medical practices and procedures is being heavily shaped by the emergence of this pandemic. COVID 19 testing has already standardized within the medical field as doctors wearing scrubs or fitness examination before operation. We are now more than 2 years into COVID-19 pandemic with more than 6 effective vaccines available in the market for public to boost and build up their immunity against the virus. Every 3 to 4 months we hear about a new strain and another wave of the virus attacking the world, therefore healthcare institutions face enormous challenges in balancing patients' needs and simultaneous safety to health care workers. The Indian council of medical research in June 2020 proposed that testing for Covid-19 for asymptomatic patients coming for elective surgeries should be performed for neurosurgery, ear nose, and throat (ENT) surgery, dental procedures, etc. and for non-surgical interventions like bronchoscopy, upper gastrointestinal endoscopy and dialysis. A role of preoperative testing of Covid-19 for every patient is still controversial especially in asymptomatic healthy patients with not known exposure to a COVID positive patient. Most patients attending eye out patient department (EOPD) are aged 65y and older are considered at a higher risk for worse outcome in case of COVID-19 infection. Therefore a rethink of a cataract surgery pathway should include preoperative perioperative and postoperative care in order to maintain safety conditions for patients and for healthcare staff. COVID-19 can infect anyone and result in transmission of infection before the patient become symptomatic or even without ever developing symptoms. Therefore preoperative screening of patients undergoing ophthalmic surgery should be considered.
