A significative proportion of patients with pulmonary-related COVID-19 initially present with « silent » or « happy » hypoxemia, a term denoting an absence of dyspnea or other respiratory distress symptoms in face of profound hypoxemia. COVID-19 is a multisystemic disease characterized by the diffusion of SARS-COV-2 through the blood and a widespread secondary immune response. Most of the organs are involved, including the brain and this translates into the development of acute encephalopathy and other complications. Silent hypoxemia and the consequent "vanishing dyspnea" represent a loss of warning signal and may be associated with a rapid clinical worsening and a fatal outcome. In this article, we will describe the physiological basis of ventilation and we will elucidate the different pathophysiological mechanisms underlying the phenomenon of silent hypoxemia in COVID-19.Various neuromuscular complications have been described in SARS-CoV-2 infection, especially Guillain-Barré syndrome (GBS) and Critical Illness neuromyopathy (CI-NM). Two representative cases are discussed below. It appears that GBS shares most of the characteristics of classical post-infectious GBS, but SARS-CoV-2 may contribute to the increased incidence of CI-NM. Other rare complications have been described, including Tapia Syndrome and Kawasaki-like multiple system inflammatory syndrome. The question of vaccination and the risk of immune-mediated neuropathies remains open, but the lack of reported cases is reassuring as these complications usually occur within 6 weeks after vaccination.Among the long-COVID symptoms, neuropsychological sequelae are frequent after an infection by SARS-CoV-2, whatever the severity of the respiratory disease in the acute phase. These deficits seem to result from a neurological disorder, but also from psychiatric symptoms. Not only inflammatory components, which can play a major role in the genesis of the neuropsychological sequelae, but also the hypotheses of vascular systemic lesions, the neurotropism of SARS-CoV-2, or the effect of the stress and the hypothalamic-pituitary-adrenal axis (HPA) are suggested. Psychiatric complications due to SSARS-CoV-2 infection would partly explain these neuropsychological sequelae.COVID-19 patients are at a higher risk of stroke. This observation is in apparent contradiction with the reduced number of stroke patient admissions during the first wave of the COVID-19 pandemic, seen worldwide. The SARS-CoV-2 can affect the endothelium, favour a procoagulant state and involves the heart, leading to an increased risk of developing a stroke. The pandemic and confinement influence the behaviour of the population, perhaps more reticent to contact emergency departments flooded with COVID-19 patients and likely to have modified levels of stress. In addition, it was shown that confinement during the pandemic reduced air pollution, thought to affect stroke risk. These indirect effects of SARS-CoV-2 probably also impact the number of hospital admissions for stroke. These different aspects are presented here as a controversy.Acute encephalopathy is one of the most frequent neurological complication in patients hospitalized for COVID-19. Electrolyte imbalance, drugs, and hypoxemia can all affect brain homeostasis, leading to acute cognitive dysfunction and direct implications of the SARS-CoV-2 are not completely understood. Neurological complications of SARS-CoV-2 infection are poorly understood an inflammatory insult to the endothelium affecting the blood-brain barrier may explain the clinical presentation, but other hypotheses including direct viral damage or an immune-mediated reaction are also suggested. Among these various potential mechanisms, often combined, the controversy remains. Dendritic cells (DCs) are administered as immunotherapeutic adjuvants after the completion of standard treatment in most settings. However, our Phase I trial indicated that one patient out of four, who received autologous tumor lysate-pulsed dendritic cell (TLDC) also received cisplatin chemotherapy and experienced complete regression of her lung lesion, continuing to be disease free till date. Hence, the objective of our current study is to evaluate the sustenance or augmentation of immune responses when autologous human papillomavirus positive cervical tumor lysate pulsed DC- are combined with cisplatin, using co-culture assays in vitro. Before treatment, peripheral blood and punch biopsy samples were collected from 23 cervical cancer patients after obtaining an informed consent. DC functionality was confirmed through phenotypic and functional assays using autologous peripheral blood mononuclear cells as responders. For cisplatin experiments, the drug was added at 150, 200 (clinical dose equivalent), ansplatin treatment may be given after autologous TLDC administration to maintain or improve a productive anti-tumor response in vaccinated patients. Common robotic training curricula in the US entail completion of an online module followed by lab training with standardized exercises, such as manipulating needles with robotic needle drivers. Assessments are generally limited to elapsed time and subjective proficiency. We sought to test the feasibility of a simulation-based robotic hysterectomy curriculum to collect objective measurements of trainee progress, map the trainee learning curve and provide a system for trainee-specific evaluation. An observational cohort study of a single institutions' residency members participating in a procedural hysterectomy simulation performed every 4 months. Each simulation episode had one-on-one teaching. The robotic platform was used to measure all movements within cartesian coordinates, the number of clutches, instrument collisions, time to complete the simulated hysterectomy, and unintended injuries during the procedure. Voluntary participation was high. Objective metrics were successfully recorded at each session and improved nearly universally. More senior residents demonstrated superior capabilities compared to junior residents as expected. The majority of residents (29/31) were able to complete an entire simulated hysterectomy in the allotted 30-minute training session period by the end of the year. This program establishes learning curves based on objective data points using a risk-free simulation platform. The curves can then be used to evaluate trainee skill level and tailor teaching to specific objective competencies. The pilot curriculum can be tailored to the unique needs of each surgical discipline's residency training.This program establishes learning curves based on objective data points using a risk-free simulation platform.
