The modified Preoperative Anxiety Scale (mPAS) questionnaire as given in the article by Viola et al, will be used after permission from the authors, to investigate the preoperative anxiety of patients undergoing surgery during the 4th wave of the pandemic
Urinary incontinence (UI) is defined as any involuntary loss of urine. It affects a significant percentage of the population, mainly female, with a prevalence of 21.4% in Portuguese women, having a negative impact on quality of life and sexual function. About half presents with stress UI (SUI), followed by mixed UI (MUI), with isolated urgency UI being less common. Pelvic floor rehabilitiation is a first line treatment for SUI and MUI, however, it is not yet defined which is the best treatment program or the ideal strategies to improve adherence to it. Telerehabilitation assumed a leading role in the covid pandemic phase, although there are few studies on pelvic floor rehabilitation for UI, none in Portugal to date. The authors aim to evaluate the effectiveness of a hybrid program of pelvic floor rehabilitation in female patients with SUI and MUI with a predominance of SUI, including consultation and face-to-face sessions complemented with telerehabilitation.
The aim of this study is to describe the patient clinical profile, resource requirements, and health system dynamics in a field hospital during the second wave of the Coronavirus (COVID-19) pandemic, leading to the outbreak of viral severe acute respiratory syndrome (SARS-CoV-2 virus), in South Africa. By describing the field hospital in this unique setting, the investigators hope to provide an efficient guide to similar settings across low- and middle-income countries. This was a retrospective, single-center study. A total of 596 patients with confirmed COVID-19 were admitted to Mitchells Plain Hospital of Hope (MPHOH), Cape Town, South Africa, between January 1st and February 28th, 2021. Patient clinical characteristics, outcome, and resource allocation was collected. Daily hospital dynamics, including admissions, discharges, deaths and oxygen use was analyzed and compared to the local and national COVID-19 incidence rates.
This trial is Stage 2 of a 2-part adaptive trial. The study aims to investigate the safety of 2 doses of a T-cell priming specific cocktail of Coronaviruses peptides mounted on a gold nanoparticle. Note: Stage 1 of the 2-part adaptive trial, testing a specifically selected mix of Dengue virus peptides, commenced Aug 2021. This is now in follow up (NCT04935801).
This is a first in human, phase I, open-label, dose-escalation study to assess the safety, reactogenicity, and immunogenicity of a SARS-CoV-2 Vaccine (IN-B009) in healthy adults.
In late 2019, a new coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was identified as the cause of COVID-19 (COronaVIrus Disease-2019) in Hubei Province, China. COVID-19 has become a pandemic with approximately 4.1 million confirmed cases as of May 2020 resulting in 280,000 deaths worldwide. Between 5 and 20% of patients hospitalized with SARS-CoV-2 infection are admitted to the ICU with a mortality ranging from 25 to 60% depending on the series. At present, there is no effective targeted therapy against this viral infection. High-density lipoproteins (HDL) are nanoparticles made up of apolipoproteins, mainly apoA1, associated with phospholipids whose main function is the reverse transport of cholesterol from peripheral tissues to the liver. This property gives HDL a major cardiovascular protective effect. In addition to this effect, studies have highlighted a number of properties such as anti-inflammatory, anti-apoptotic, anti-thrombotic and anti-oxidant effects of these particles. Furthermore, it has been shown that HDL is able to bind and neutralize bacterial lipopolysaccharides (LPS), promoting their elimination. During bacterial sepsis, a rapid decrease in plasma HDL cholesterol (HDL-C) concentration has been demonstrated, but also an inverse correlation between mortality and HDL-C concentration. In addition to the quantitative decrease in HDL during sepsis, dysfunctions of these particles have been described, such as major differences in size, or a notable alteration in protein composition with, in particular, more pro-inflammatory proteins. In this context of both quantitative and qualitative alteration of HDL, authors have tested the efficacy of injection of either reconstituted HDL (apoA1 + phosphatidylcholines) or peptides structurally similar to ApoA1 in animal models of sepsis and have demonstrated a protective effect on morbidity and mortality, with in particular a decrease in the inflammatory state induced by sepsis. Low-density lipoproteins (LDL) can also neutralize LPS and observational studies have shown a decrease in the concentration of LDL cholesterol (LDL-C) during sepsis. The authors also showed that low LDL-C was associated with a poor prognosis in patients with sepsis. During COVID-19-induced sepsis, a few studies have demonstrated a decrease in lipoprotein (HDL and LDL) concentration. More specifically, some authors have found an association between low lipoprotein concentrations and increased disease severity. To the best of the knowledge of the investigators, no study has specifically investigated particulate dysfunction of lipoproteins and in particular HDL during severe COVID-19 infections. On the other hand, as it has been described that lipoproteins and particularly HDL can bind bacterial components (LPS or LTA) favoring their clearance, it can be envisaged that these particles can also bind SARS-CoV-2 components, and this, in a more or less strong way depending on the virus strain. The preliminary results of the investigators show that in sepsis, serum amyloid A (SAA) protein tends to replace apolipoprotein A1, making HDL dysfunctional. In addition, paraoxonase-1, an antioxidant enzyme mainly carried by HDL, is almost absent or degraded in septic patients. The SAA/PON-1 ratio could allow to assess the severity of COVID-19 damage and to reinforce a possible therapeutic strategy based on the supplementation of severe patients with apolipoprotein A1 and PON-1 rich HDL nanoparticles. Main objective: To evaluate the functionality of HDL as a prognostic marker of mortality in COVID-19 patients in ICU. To do so, a quantification of the SAA/PON-1 ratio at plasma level and on isolated lipoproteins will be performed by ELISA.
This study aimed to determine the role of in situ simulation training during a pandemic by using standard and high-fidelity mannequins to improve interprofessional communication, skills, and teamwork in transferring critically ill COVID-19 patients.
This is a pilot, randomized, single-center, parallel group, open-label controlled study to evaluate the feasibility, safety, efficacy, and pharmacokinetics of nebulized HCQ01 plus Standard of Care (SOC) versus SOC alone in hospitalized COVID-19 patients. The Jordanian Ministry of Health (MOH) is the study sponsor, and the study will be conducted at MOH COVID-19 hospitals. Approximately 110 patients, ≥18 years of age with a confirmed SARS-CoV-2 infection, will be enrolled and randomized 1:1 to the treatment and control arms where they will receive ten doses of Hydroxychloroquine solution via nebulizer in addition to SOC or the control arm where treatment will follow the MOH SOC.
This is a multicenter, double-blind, randomized, placebo-controlled phase 2/3 clinical study. Based on the results of the Phase I clinical study, one repeat dose group and one placebo group are used for the standard treatment of the Novel Coronavirus Pneumonia Protocol (Trial 8) The treatment regimen is a one-time intravenous infusion of either mprozumab or placebo on day 1 (D1) and day 8 (D8) of the treatment period at a dose of 0.2 mg/kg based on body weight. An estimated 150 subjects will be randomly assigned to either Meplazumab or placebo in a 2:1 ratio A short-term efficacy evaluation was performed to determine the efficacy and safety of Meplazumab in each subject within 14 days of initial administration and a long-term follow-up evaluation was performed 28 days after initial administration to determine the safety of Meplazumab.
