Filter by:Introduction Most countries imposed mandatory lockdowns that were rapidly lifted, however Argentina holds the record for one of the longest quarantines in the world. General surgery emergency conditions and trauma cases still require immediate evaluation and timely resolution. The primary objective of this study was to analyze the variations in the consults, surgical outcomes and severity of disease in admissions at our department of general surgery and to study the consequences of the lockdown effect in our community. Materials and methods An observational, ambispective study was carried out on a prospective cohort of patients who consulted with on-call surgical pathology and required hospitalization in the period from March 13th, 2020 until July 31, 2020 (PG) were included, analyzed and compared with the same period of 2019 (CG).
Background: In the midst of the devastating COVID pandemic where there is no specific and effective treatment, traditional therapy may help to ease the patient's suffering. Inhalation of vapor (VP) is an essential home remedy for stuffy, running nose in common cold, influenza and sinusitis. Steam inhalation is helpful in destroying the capsid of the SARS-CoV-2 envelope and preventing infection. Vapor with diclofenac sodium, menthol, methyl salicylate and N-acetyl cysteine may augment this effect. Objective: To evaluate the effect of inhalation of vapor with medication and to compare with inhalation of vapor without medication. Methods and Materials: A case control study taken place in Corona unit, Sher-E-Bangla Medical College Hospital, Barishal. 43 patients with mild to moderate COVID-19 were participated in this study. All are RT-PCR positive cases. Among them 16 patients were in control group and 27 in study group. In study group they were given vapor with Diclofenac Sodium, Menthol, Methyl Salicylate and N-Acetyl Cysteine and control group they were given normal steam/aquatic vapor two times in a day.
The Coronavirus Disease 2019 (COVID-19), caused by the SARS-CoV-2 virus, is a worldwide pandemic that has resulted in large-scale quarantines in cities, states, and countries throughout the world. SARS-CoV-2 is a respiratory virus that is most commonly spread via contact with infective respiratory droplets and aerosols produced by coughing, sneezing, talking, and singing. Children with medical complexity (CMC), i.e., children with multiple severe chronic conditions, high resource use, severe functional limitations, and substantial family-identified service needs, are a medically vulnerable population for the development of severe COVID-19. Deciding to send CMC to school poses a major dilemma to families wanting to minimize severe COVID-19 risk. School personnel also face risks when CMC attend school. Despite these challenges, achieving in-person school attendance is critical for CMC. Compared to non-CMC, academic and social development for most CMC hinges on being at school. Severe intellectual and developmental disability impairs one's ability to engage with online platforms. Health-promoting services delivered at school, e.g., physical, occupational, and speech therapy, are likely less effective when delivered virtually. Parents of CMC, already disproportionately unemployed due to their child's care needs, experience added employment strain when their child is out of school. The study objective is to increase the safe return to school for CMC by 1) evaluating the feasibility of school-based COVID-19 testing strategies and 2) identifying parent and staff perceptions of testing and school attendance. A related study (ReSET Aim 1a, NCT04895085) will evaluate the same factors in home-based testing strategies in CMC exclusively.
Since the first local case of COVID-19 confirmed on 4 Feb 2020, Hong Kong has already experienced 4 waves of COVID-19 surge, with more than 9000 cases reported. A number of vaccines have been shown to be efficacious against symptomatic and severe infection by inducing neutralizing antibody (NAB) against spike protein of the SARS-CoV-2 virus. However, the duration of protection and longevity of antibody response is unknown. Health care workers (HCWs) who are planning to receive COVID-19 vaccine will be recruited. The level of antibody against spike protein by different quantitative assays will also be serially measured .
The rapid spread and increase of acute respiratory infection cases caused by the novel SARS-CoV-2 coronavirus represent a major challenge for healthcare systems around the world. The shortage of facilities and medical personnel is a major problem in the face of a serious epidemic. The Lombardy Region, and in particular the territories of Milan, Bergamo and Brescia, was the most affected due to the rapid increase in cases and limited medical resources during the initial phase of the epidemic. The collaboration between hospital and territory with integrated communication systems and the monitoring of patients with appropriate technological tools that include telemedicine, are fundamental to ensure the continuity of care and the sustainability of the health system, also significantly reducing the risk of contagion for health professionals.
Coronavirus disease 2019 (COVID-19) can cause variable symptoms ranging from mild common cold-like symptoms to severe life threatening pneumonia. Recent studies show severe outcomes of COVID-19 patients specially in males who suffer from androgenetic alopecia, would be significant and is of particular interest of this study and could help further support the hypothesis that anti-androgen therapy might represents an additional potential intervention against severe COVID-19.
The aim of the research is to estimate the levels of cellular and humoral immunity to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among Moscow residents over 18 years old. During the study, participants will be divided into four groups: healthy volunteers; individuals recovered from coronavirus disease 2019 (COVID-19) with different severity; individuals vaccinated against SARS-CoV-2; individuals who have had COVID-19 concomitantly with comorbidities that characterized by the impact on the immune system (tuberculosis, chronic obstructive pulmonary disease, HIV infection, hematological neoplasia). For all participants included into the study peripheral blood will be collected and the titers of SARS-CoV-2 specific immunoglobulins M (IgM) and immunoglobulins G (IgG), frequencies of the T cells specific to nucleocapsid (N), membrane (M), and spike (S) proteins of SARS-CoV-2 in peripheral blood, as well as the fractions of virus specific T helpers and cytotoxic T cells will be estimated. For smaller cohorts of the participants in all groups the antibody titers and T cell response levels will be examined in dynamics. All participants will be monitored for the incidence of primary or repeated COVID-19 for 1-2 years after inclusion in the study. Based on the results of the study, the relationship between the formation of humoral and cellular immunity against COVID-19, the duration of these types of immunity, as well as their individual contribution to protection against primary or secondary SARS-CoV-2 infection will be analyzed. Additionally, data concerning patients recovered from COVID-19 and having concomitant diseases will provide a valuable information that may help to understand in more details the mechanisms of the development of the SARS-CoV-2 specific immune response.
Our aim in this study is to determine the positive effect of stem cell therapy applied on critically ill patients with coronavirus infection on DNA repair genes. Patients diagnosed with COVID-19 infection are divided into two equal (n:30) groups. Group-1(n/15): Patients in critically ill condition receiving conventional therapy, Group-2 (n/15): Patients in critically ill condition receiving conventional therapy and systemically transplanted MSCs. The DNA repair pathway will be examined as 11 genes in 5 different parts. Investigated parameters: 1. Base excision repair 2. Nucleotide excision repair 3. Recombinational repair 4. Mismatch repair 5. Direct reversal Investigated parameters: broad biochemical analysis, apoptosis, clinical outcome, and mortality rates.
Spontaneous pneumomediastinum (PMS) is defined as free air within the mediastinum. Spontaneous pneumothorax (PNX) consists of the presence of air inside the pleural space. PMS and PNX may sometimes occur secondly to an underlying pathology, or deriving from a sudden increase in intra-alveolar pressure such as functional alteration such as airway hyperactivity, Valsalva maneuver, cough, barotrauma, and/or volutrauma with consequent rupture of the alveoli and subsequent leakage of air into the mediastinum due to the Macklin effect. The escaping air can then spread inside the pericardium, the peritoneum, the muscles, and subcutaneous tissues, hence causing subcutaneous emphysema. PMS and PNX are rare complications of several lung infections such as Pneumocystis Jirovecii pneumonia, tuberculosis, bacterial necrotizing pneumonia, and herpes pneumonia. However, an increasing number of PMS and PNX has been described in patients with SARS-CoV2 interstitial pneumonia. PMS and PNX can either present as the onset manifestation of COVID-19 disease, or occur as complications of non-invasive and/or invasive ventilation, or following to cystic and/or fibrotic evolution of the pathology. The frequency of PMS and PNX during COVID-19 is not well defined, as the available data are limited to case collections and single reports. According to currently available scientific literature, PNX in COVID-19 occurs with frequency rates of 1-3%, up to 6% in patients undergoing non-invasive ventilation (NIV) and mechanical artificial ventilation (VAM). In McGuinness's analysis, which compared the complications of barotrauma in patients with acute respiratory distress syndrome (ARDS) in VAM, PNX and PMS occurred with frequency rates of 9% and 10%, respectively, while in non-COVID-19 population, PNX and PMS frequency rates were 12% and 3%, respectively.
SARS COV2, the virus that causes COVID-19, was first described in Wuhan, China. For this pathology, which causes severe respiratory infections, preventing the transmission of the virus has become fundamental, that is why vaccines have been developed. In France, this vaccination campaign took place in a context where the lack of confidence in vaccination is high: According to a November 2020 IFOP poll, only 41% of French respondents were willing to be vaccinated against COVID-19. To our knowledge, there are still few qualitative studies on vaccination on the current issue of vaccination against COVID-19.
