Adverse Events and Safety of SARS-CoV-2 Vaccines: What's New and What's Next.

Just over 1 year following rollout of the first vaccines for coronavirus disease 2019, 572 million doses have been administered in the United States. Compared with the number of vaccines administered, adverse effects such as anaphylaxis have been rare, and seemingly, the more serious the effect, the rarer the occurrence. Despite these adverse effects, there are few, if any, true contraindications to coronavirus disease 2019 vaccination and most individuals recover without further sequelae.

ATN incorporating cerebrospinal fluid neurofilament light chain detects frontotemporal lobar degeneration.

Introduction: The ATN framework provides an in vivo diagnosis of Alzheimer's disease (AD) using cerebrospinal fluid (CSF) biomarkers of pathologic amyloid plaques (A), tangles (T), and neurodegeneration (N). ATN is rarely evaluated in pathologically confirmed patients and its poor sensitivity to suspected non-Alzheimer's pathophysiologies (SNAP), including frontotemporal lobar degeneration (FTLD), leads to misdiagnoses. We compared accuracy of ATN (ATN ) using CSF total tau (t-tau) to a modified strategy (ATN ) using CSF neurofilament light chain (NfL) in an autopsy cohort.

Involvement of Pro-Inflammatory Macrophages in Liver Pathology of Pirital Virus-Infected Syrian Hamsters.

New World arenaviruses cause fatal hemorrhagic disease in South America. Pirital virus (PIRV), a mammarenavirus hosted by Alston’s cotton rat (), causes a disease in Syrian golden hamsters () (biosafety level-3, BSL-3) that has many pathologic similarities to the South American hemorrhagic fevers (BSL-4) and, thus, is considered among the best small-animal models for human arenavirus disease. Here, we extend in greater detail previously described clinical and pathological findings in Syrian hamsters and provide evidence for a pro-inflammatory macrophage response during PIRV infection.

Brugada Syndrome Induced by an Interscalene Block: A Case Report.

Case: A 57-year-old woman with no noteworthy medical or surgical history underwent an interscalene block with bupivacaine in preparation for an arthroscopic rotator cuff repair. Following administration of the bupivacaine, the patient sustained a ventricular fibrillation arrest. After successful cardiopulmonary resuscitation, she was diagnosed with Brugada syndrome.

Tobacco Product Use Among Adults - United States, 2015.

Tobacco use remains the leading cause of preventable disease and death in the United States (1). Despite declining cigarette smoking prevalence among U.S.

HLA targeting efficiency correlates with human T-cell response magnitude and with mortality from influenza A infection.

Experimental and computational evidence suggests that HLAs preferentially bind conserved regions of viral proteins, a concept we term "targeting efficiency," and that this preference may provide improved clearance of infection in several viral systems. To test this hypothesis, T-cell responses to A/H1N1 (2009) were measured from peripheral blood mononuclear cells obtained from a household cohort study performed during the 2009-2010 influenza season. We found that HLA targeting efficiency scores significantly correlated with IFN-γ enzyme-linked immunosorbent spot responses (P = 0.

Genetic modifiers of liver disease in cystic fibrosis.

Context: A subset (approximately 3%-5%) of patients with cystic fibrosis (CF) develops severe liver disease with portal hypertension.

Objective: To assess whether any of 9 polymorphisms in 5 candidate genes (alpha(1)-antitrypsin or alpha(1)-antiprotease [SERPINA1], angiotensin-converting enzyme [ACE], glutathione S-transferase [GSTP1], mannose-binding lectin 2 [MBL2], and transforming growth factor beta1 [TGFB1]) are associated with severe liver disease in patients with CF.

Design, Setting, And Participants: Two-stage case-control study enrolling patients with CF and severe liver disease with portal hypertension (CFLD) from 63 CF centers in the United States as well as 32 in Canada and 18 outside of North America, with the University of North Carolina at Chapel Hill as the coordinating site.

Co-morbidity of select anxiety, affective, and psychotic disorders with cannabis dependence in Southwest California Indians.

Cannabis dependence is co-morbid with psychiatric disorders in general population surveys, but whether co-morbidity exists in American Indian populations is unknown. The aim of this study was to assess co-morbidity between cannabis dependence and psychiatric disorders in a community sample of Southwest California (SWC) Indians. Demographic information and DSMIII- R diagnoses, including differentiation of independent and cannabis-induced psychiatric disorders, were obtained using the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA) developed for the Collaborative Study on the Genetics of Alcoholism (COGA) from 513 SWC Indian adults residing on contiguous reservations.

You are what you eat: describing the foraging ecology of southern elephant seals (Mirounga leonina) using blubber fatty acids.

Understanding the trophodynamics of marine ecosystems requires data on the temporal and spatial variation in predator diet but, particularly for wide-ranging species, these data are often unavailable. The southern elephant seal (Mirounga leonina) consumes large quantities of fish and squid prey in the Southern Ocean relative to other marine mammals; however, how diet varies relative to seasonal and spatial foraging behaviour is unknown. We used fatty acid (FA) signature analysis of 63 blubber cores from adult female M.

Isotretinoin and Staphylococcus aureus infection. A possible association.

The use of isotretinoin (13-cis-retinoic acid) in the treatment of numerous dermatologic disorders, as well as the side effects encountered with use of the drug, have increased remarkably since its release. We encountered a case of Staphylococcus aureus endocarditis in a patient with chronic stable aortic insufficiency undergoing therapy with isotretinoin for extensive actinic keratoses. Although significant dysfunction of the immune system has not been demonstrated with isotretinoin, nasal colonization with S aureus has been shown to occur.
