The Value of Home Chlorhexidine Pre-Surgical Wash Before Spine Surgery
InfectionSpinal InjuriesThe study team hypothesizes that at-home cleansing of the surgical site with chlorhexidine wipes provide no added benefit to decreasing microbial activity or preventing surgical site infections. Patients will be randomized to the chlorhexidine or no additional intervention groups. Patients will be randomized to use 4% chlorhexidine cloths, while the other half receive no additional intervention. Those randomized into the chlorhexidine gluconate (CHG) home-application group will be asked to shower the night before surgery, and to use a standardized pre-packaged CHG wipe (that the patients would receive at their pre-surgical consultation) on their surgical site after thoroughly drying those areas. The patients will be asked to use a second wipe in each area the morning of surgery. The surgical sites will be analyzed in two groups: anterior cervical and posterior spine. Each of these two groups will be randomized separately. All patients will undergo a standardized preoperative cleansing regimen. Once positioned, they will be cleansed with an alcohol solution. Then, the surgical site (either the anterior portion of the neck or the posterior area of the spine) will be scrubbed with chlorhexidine soaked brushes and then painted with chlorhexidine solution. Perioperative antibiotics will be given per attending surgeon preference. Cutaneous samples will be taken from the surgical site of each patient at each time point.

Cervical Intraepithelial NeoplasiaHuman Papillomavirus Infection1 moreHigh-risk type human papillomavirus (HPV) is the known etiological agent of cervical cancer. HPV testing and risk stratification by genotyping has been recognized as an effective cervical screening program. A chip for HPV DNA typing based on type-specific polymerase chain reaction (PCR), DR. HPV Genotyping IVD Kit (HPV-27) was developed for genotyping of 27 common HPV types including all high-risk types. We studied its agreement, sensitivity, and specificity compared to DNA sequencing as the gold standard.

Nitric Oxide Releasing Solutions to Prevent and Treat Mild/Moderate COVID-19 Infection
Corona Virus InfectionThis is a multi-center, randomized, controlled, phase II clinical efficacy study evaluating a novel Nitric Oxide Releasing Solution (NORS) treatment for the prevention and treatment of COVID-19 in healthcare workers at risk of infection. Participants will be enrolled into one of two components of this study. Based on initial swabs/symptoms, volunteers who are COVID-19 negative will be enrolled in the Prevention study and randomized to receive standard institutional precautions or standard institutional precautions + NORS. Those who are COVID-19 positive will be enrolled in the open-label Treatment Sub-Study.

Tocilizumab for the Treatment of Cytokine Release Syndrome in Patients With COVID-19 (SARS-CoV-2...
Cerebrovascular AccidentChronic Obstructive Pulmonary Disease5 moreThis phase III trial compares the effect of adding tocilizumab to standard of care versus standard of care alone in treating cytokine release syndrome (CRS) in patients with SARS-CoV-2 infection. CRS is a potentially serious disorder caused by the release of an excessive amount of substance that is made by cells of the immune system (cytokines) as a response to viral infection. Tocilizumab is used to decrease the body's immune response. Adding tocilizumab to standard of care may work better in treating CRS in patients with SARS-CoV-2 infection compared to standard of care alone.

Efficacy of Melatonin in the Prophylaxis of Coronavirus Disease 2019 (COVID-19) Among Healthcare...
Covid19SARS-CoV 21 moreThere is an urgent need to evaluate interventions that can prevent the infection with SARS-CoV 2 of healthcare workers at risk. Melatonin is an inexpensive and safe product with protective effect in both bacterial and viral infections likely due to its anti-inflammatory and anti-oxidative effects. This randomized controlled trial seeks to evaluate is efficacy as a prophylaxis in healthcare workers exposed to the virus in their clinical practice.

Feasibility of Non-contact Magnetically-controlled Capsule Endoscopy During COVID-19 Pandemic
Gastrointestinal DiseaseInfectious Disease1 moreIn December 2019, an outbreak of pneumonia associated with a novel coronavirus named as severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) was reported in Wuhan city, China, and spread exponentially throughout China and other countries in the following weeks. It is recommended that elective endoscopies should be deferred during the COVID-19 outbreak for the potential transmission between patients and medical staff in the statements of Asian Pacific Society for Digestive Endoscopy (APSDE-COVID statements). Therefore, exploring an alternative for patients with the requirements of endoscopy during the outbreak is of great importance. Herein,the investigators developed an novel non-contact magnetically-controlled capsule endoscopy (Nc-MCE) system (Figure 1) adds a remote control workstation and a audio-visual exchange system to the original well-established MCE system. This study was a open-label, prospective, randomized controlled study approved by the institutional review board of Shanghai Changhai Hospital. It was designed to evaluate the diagnostic utility, safety, feasibility and patients acceptability of Nc-MCE in patients with an indication of endoscopy, and comparing it with the result of MCE.

Hydroxychloroquine to Prevent SARS-CoV-2 Infection/COVID-19
SARS-CoV-2The purpose of this study is to determine whether hydroxychloroquine is an effective prophylactic regimen to prevent SARS-CoV-2 infection among healthcare workers. Participants will be randomized into two parallel groups. The first arm will evaluate the use of hydroxychloroquine every-other-day plus standard measures of protection for the prevention of SARS-CoV-2. The second arm will evaluate the use of standard measures of protection for the prevention of SARS-CoV-2. The target enrollment is 320 participants. Each study participant will be monitored for SARS-CoV-2 seroconversion in weekly visits or for the development of COVID-19 symptoms for 8 weeks.

Effectiveness of a Novel Respirator With Chitosan Nanoparticles
Covid19SARS-CoV Infection2 moreThe use of nanomaterials in semi-facial respirators could decrease the permeability of particles and promote a biocidal effect compared to conventional respirators (N95) and, therefore, to enhance the filtering power, aiming to mitigate harmful effects of bacteria and viruses. Chitosan is a natural cationic polymer derived from chitin, with characteristics such as being biodegradable, biocompatible, non-toxic, and presenting antimicrobial activity. This polymer has virucidal activity in several types of viruses, including other coronaviruses, given the attractive factor of its cationic charge for negative charges. The effectiveness of a novel individual protection semi-facial respirator (called VESTA) will be investigated, compared to a conventional N95 respirator. The respirators will be tested in healthcare professionals working in hospital environments and the effectiveness will be attributed to the lower incidence rate of infection by the SARS-CoV-2, and to the ability to filter these viruses after use by healthcare professionals exposed to potentially contaminated environments. The study will be carried out in two stages: i) Randomized Controlled Trial with reduced sample to confirm the sample size calculation (pilot trial), and ii) Randomized Controlled Trial (RCT). The RCT will be conducted with healthcare professionals who have contact with environments/patients infected by SARS-CoV-2 in hospital sectors with greater vulnerability to infection (urgency, emergency and intensive care units). The RCT will be conducted initially with a group of sixty participants (n = 30 in each group) for initial investigation of the potential for efficacy with the use of the respirators (VESTA and conventional N95) in two sectors (emergency and ICU) in a reference Hospital for COVID-19. The RCT will consist of two parallel groups: (1) Experimental Group (GExp) that will use the novel respirator (VESTA) and (2) Control Group (CG) that will use the standard respirator (N95). Participants will be recruited from participating hospitals and will be accompanied by 21 days in approximately eight consecutive shifts (ranging from shifts lasting 6 to 12 hours each, followed by approximately 36 hours of rest). Participants will be assessed at baseline (T0), at the end of the 10th day (T1), and at the end of the 21st day (T2).
