Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of the ongoing coronavirus disease 2019 (COVID-19) pandemic, induces severe pneumonia mainly in elderly males. Epidemiological data clearly indicate sex-based differences in disease outcomes, with men accounting for about 70 % of deaths, despite similar susceptibility to infection. It is well known that females are endowed with higher capacity to produce antibodies, which correlates with viral clearance and disease resolution in the context of SARS-Cov-2 infection. BLU-222 supplier Many X-linked immune genes escape X inactivation showing biallelic expression in female immune cells, particularly in plasmacytoid dendritic cells (pDCs). PDCs are more active in females and endowed with high capability to induce IFN-α-mediated B cell activation and differentiation into antibody-producing plasma cells throughout epigenetic mechanisms linked to trained immunity. BLU-222 supplier Thus, we hypothesize that following SARS-CoV-2 infection, epigenetic modifications of X-linked genes involved in pDC-mediated type I IFN (IFN-I) signaling occurs more effectively in females, for inducing neutralizing antibody response as an immune correlate driving sex-biased disease outcome.Invasive pneumococcal infection, defined as the combination of pneumonia with endocarditis and meningitis, was described as Austrian syndrome in the 1800s. We report the case of a 63-year-old woman with underlying human immunodeficiency virus who presented with fever and altered mental status. Subsequent workup supported a diagnosis of Austrian syndrome. During the 5-week course of ceftriaxone treatment, she developed fever, pruritus and follicular accentuation throughout the body. Labs were significant for eosinophilia, which along with systemic symptoms, supported the diagnosis of a drug reaction. Coagulase negative staphylococcus bacteremia was discovered when the patient developed septic shock. Subsequently, diffuse desquamative eruption with rapidly progressing sloughing appeared and biopsy proved toxic epidermal necrolysis. Patient eventually succumbed to multiorgan failure.One of the human natural defense systems protects against nontuberculous mycobacterial (NTM) infection by IFN-γ producing T lymphocyte cells. Most disseminated NTM infections usually occur in severe immune-compromised patients, such as HIV infection or after organ transplant patients. However, there have been several reports of non-compromised patients with disseminated NTM infection, including antibiotic resistance cases and the presence of a neutralizing antibody against IFN-γ. We elucidated the anti-IFN-γ neutralizing antibody in a 65 year-old Japanese man whose legs were paralyzed because of multiple abscesses in vertebral bodies. Although his vertebral bodies were released due to an operation and antibiotics were administered, this treatment efficacy was poor. Patient's plasma demanded not only IFN-γ expression in peripheral blood mononuclear cells (PBMC) obtained from healthy controls, but also recombinant human IFN-γ expression. Furthermore, IFN-γ receptor expression was increased, compared to the healthy control. Finally, anti-IFN-γ antibody was detected in his plasma. These results suggested that anti-IFN-γ antibody induced an incurable NTM infection. IFN-γ was subcutaneously administrated with antibiotics, and then the abscesses diminished and his general condition was successfully improved. This therapy might be useful against severe NTM infections.Coronary angiography is one of the most common procedures done in the United States and in other developed countries. For decades, the femoral artery has been the most common vascular access site utilized for this procedure. However, the radial access has been gaining popularity for being a safer and yet practical vascular access with substantial benefits. More recently, the novel distal transradial approach has proven to be an equally or perhaps safer vascular access for diagnostic and interventional coronary and noncoronary procedures. This technique should be in every interventional cardiologist's arsenal.Proteases are critical virulence determinants of Porphyromonas gingivalis, an emerging Alzheimer's disease, cancer, and arthritis pathogen and established agent of periodontitis. Transposon sequencing has been employed to define the core essential genome of this bacterium and genes conditionally essential in multiple environments - abscess formation; epithelial colonization; and cigarette smoke toxin exposure; as well as to elucidate genes required for iron acquisition and a functional type 9 secretion system. Validated and predicted protein catabolism genes identified include a combination of established virulence factors and a larger set of seemingly more mundane proteolytic genes. The functions and relevance of genes that share essentiality in multiple disease-relevant conditions are examined. These common stress-related genes may represent particularly attractive therapeutic targets for the control of P. gingivalis infections.During the early months of the COVID-19 pandemic, infection prevention and control (IP&C) for women in labor and mothers and newborns during delivery and receiving post-partum care was quite challenging for staff, patients, and support persons due to a relative lack of evidence-based practices, high rates of community transmission, and shortages of personal protective equipment (PPE). We present our IP&C policies and procedures for the obstetrical population developed from mid-March to mid-May 2020 when New York City served as the epicenter of the pandemic in the U.S. For patients, we describe screening for COVID-19, testing for SARS-CoV-2, and clearing patients from COVID-19 precautions. For staff, we address self-monitoring for symptoms, PPE in different clinical scenarios, and reducing staff exposures to SARS-CoV-2. For visitors/support persons, we address limiting them in labor and delivery, the postpartum units, and the NICU to promote staff and patient safety. We describe management of SARS-CoV-2-positive mothers and their newborns in both the well-baby nursery and in the neonatal ICU. Notably, in the well-baby nursery we do not separate SARS-CoV-2-positive mothers from their newborns, but emphasize maternal mask use and social distancing by placing newborns in isolates and asking mothers to remain 6 feet away unless feeding or changing their newborn. We also encourage direct breastfeeding and do not advocate early bathing. Newborns of SARS-CoV-2-positive mothers are considered persons under investigation (PUIs) until 14 days of life, the duration of the incubation period for SARS-CoV-2. We share two models of community-based care for PUI neonates. Finally, we provide our strategies for enhancing communication and education during the early months of the pandemic.
