Peripheral Immune-Mediated Neuropathy Before and During the COVID-19 Pandemic: A Retrospective Cross-Sectional Study in a Referral Center.

Background: There are currently seven coronaviruses that can infect humans and the latest addition to these viruses is the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Infection by SARS-CoV-2 is known commonly as coronavirus disease 2019 (COVID-19). Aside from common manifestations of cough and fever, neurologic symptoms such as headache, disturbed consciousness, paresthesia, and seizures have also been seen.

[F]F-AraG Uptake in Vertebral Bone Marrow May Predict Survival in Patients with Non-Small Cell Lung Cancer Treated with Anti-PD-(L)1 Immunotherapy.

Despite the systemic impact of both cancer and the associated immune response, immuno-PET is predominantly centered on assessment of the immune milieu within the tumor microenvironment. The aim of this study was to assess the value of [F]F-AraG PET imaging as a noninvasive method for evaluation of system-wide immune status of patients with non-small cell lung cancer before starting immunotherapy. Eleven patients with advanced non-small cell lung cancer were imaged with [F]F-AraG before starting immunotherapy.

Post-acute CoVid-19 syndrome (PACS) linked cardiovascular symptoms.

Officials have marked the end of the CoVid-19 pandemic, yet we continue to learn more about the SARS-CoV2 virus itself and its lasting multidimensional effects after acute infection. Long COVID, or the post-acute CoViD-19 syndrome (PACS), manifests as a wide range of prolonged physical, mental, and emotional symptoms over at least 1 to 12 months after SARS-CoV2 infection. Here, we describe certain pervasive clinical consequences of PACS on the cardiovascular system, and insight on the potentially improved prognoses in heart failure patients.

CD71: Role in permafrost immunity.

Iron, an essential constituent of cell metabolism, is transported intra-cellularly bound to the ubiquitous 76 kDa blood glycoprotein transferrin via the transferrin receptor, CD71. Because of its structure, CD71 facilitates the binding and penetration of a large variety of viruses into the host. Among which the hemorrhagic fever-causing New World mammarena viruses (family of single stranded ambisense segmented RNA Arenaviridae), the single stranded positive sense RNA hepatitis C virus, the single stranded negative sense segmented influenza A virus, the single stranded negative sense RNA rabies virus, the single stranded positive sense SARS-CoV2 and possibly many others.

Nutrition adequacy in the late period of the acute phase is associated with a lower risk of 30-day mortality in critically ill patients: A prospective cohort study.

Background: The provision of nutrition support for critically ill patients in the early phase of intensive care unit (ICU) admission plays a vital role in their recovery. However, there is still debate regarding the impact of nutrition adequacy of critical illness phases. We aimed to investigate whether nutrition adequacy in the acute phase (early and late periods) is associated with 30-day mortality in critically ill patients.

Nipah: The looming post-covid pandemic.

First identified as a pathogen in Malaysia and Singapore in 1999, Nipah virus (NiV) caused nearly 300 human cases and over 100 fatalities. It also killed about 1 million pigs. Three years later (2002), it was reported in Pteropus bats in Malaysia, in Cambodia & Thailand, (2005), and as far as Madagascar (2007) and Ghana (2008).

Improving primary prophylaxis of variceal bleeding by adapting therapy to the clinical stage of cirrhosis. A competing-risk meta-analysis of individual participant data.

Background & Aims: Non-selective β-blockers (NSBBs) and endoscopic variceal-ligation (EVL) have similar efficacy preventing first variceal bleeding. Compensated and decompensated cirrhosis are markedly different stages, which may impact treatment outcomes. We aimed to assess the efficacy of NSBBs vs EVL on survival in patients with high-risk varices without previous bleeding, stratifying risk according to compensated/decompensated stage of cirrhosis.

CoViD-19 effects on social-emotional development: Putative underlying mechanisms.

Early childhood is the timely and critical period in the growth of the human being when the trajectory of children's holistic development is traced, and the foundation for their future as well-established and productive adults is set. The CoViD-19 pandemic produced profound changes in everyday life almost everywhere in the world. The personal, social and societal restrictions imposed during the CoViD-19 pandemic unquestionably blunted early childhood development by depriving young children from normal and healthy attachments through secure relationships with parents, teachers and peers.

The lymphatic system: a pathway for meta-inflammation in permafrost immunity.

The lymphatic system is the anatomical substratum of immunity. Lymphatics collect tissue exudates, which contain cell debris, peptides, micronutrients and pathogens, as well as immune naive and memory effector cells from the body tissues and organs into the lymph. Lined by endothelial cells cemented together by tight junctions to ensure their impermeability, lymphatics contain valves that prevent the backward flow of the lymph as it moves forward toward the right and left venous angles, the anatomical site of confluence with the venous blood.

Permafrost viremia and immune tweening.

The immune system, an exquisitely regulated physiological system, utilizes a wide spectrum of soluble factors and multiple cell populations and subpopulations at diverse states of maturation to monitor and protect the organism against foreign organisms. Immune surveillance is ensured by distinguishing self-antigens from self-associated with non-self (e.g.

Evidence-based modalities in the management of Psoriasis and Psoriatic arthritis.

Psoriasis is a waxing and waning skin disorder, often associated with a plethora of co-morbidities, including psoriatic arthritis (PsA), a severe form of chronic inflammatory arthritis. All forms of psoriasis and PsA are immune-mediated diseases where the patient's immune system is overactive in the production of certain factors that stimulate and activate the function of certain immune cells. Recent evidence has uncovered an important role for cell-mediated immunity in the aetiology and course of psoriasis and PsA, with a critical role played by the pro-inflammatory IL-23/TH17 axis.

Colliding Pandemics and CoViD-19.

Cases of the respiratory syncytial virus (RSV), monkeypox virus (MPXV), and avian influenza A Virus (IAV) have increased during our current prolonged Corona Virus Disease 2019 (CoViD-19) pandemic. The rise of these viral infectious diseases may be associated or even inter-dependent with acute, latent or recurrent infection with Systemic Acute Respiratory Syndrome Corona virus-2 (SARS-CoV2). The nonsensical neologism 'tripledemic' was tentatively introduced to describe the confluent nature of these trends (epidemic comes from two Greek words: =on, about, =people; pandemic is also derived from Ancient Greek: =all, =people; but 'tripledemic' would derive from Latin =three, Greek =people, and would at best signify 'three countries, three peoples', but certainly not the current threat of confluence of three, or perhaps more pandemics).

Post acute CoViD-19 syndrome (PACS) - Long CoViD.

Patients sero-positive for the Systemic Acute Respiratory Syndrome Corona virus2 (SARS-CoV2) virus develop the Corona Virus Disease 2019 (CoViD-19). CoViD-19 may be asymptomatic in some individuals, proffer mild symptoms in other patients, and can be a serious and even lethal disease in a sub-group of the population. The variables that determine the severity of CoViD-19 have not been fully characterized.

Fructose induced KHK-C can increase ER stress independent of its effect on lipogenesis to drive liver disease in diet-induced and genetic models of NAFLD.

Non-alcoholic fatty liver disease (NAFLD) is a liver manifestation of metabolic syndrome, and is estimated to affect one billion individuals worldwide. An increased intake of a high-fat diet (HFD) and sugar-sweetened beverages are risk-factors for NAFLD development, but how their combined intake promotes progression to a more severe form of liver injury is unknown. Here we show that fructose metabolism via ketohexokinase (KHK) C isoform leads to unresolved endoplasmic reticulum (ER) stress when coupled with a HFD intake.

Carbon nanotube pathogenicity conforms to a unified theory for mesothelioma causation by elongate materials and fibers.

The purpose of this review is to elucidate how dimensional and durability characteristics of high aspect ratio nanomaterials (HARN), including carbon nanotubes (CNT) and metal nanowires (MeNW), contribute to understanding the fiber pathogenicity paradigm (FPP), including by explaining the structure-activity relationships (SAR) of a diverse range of natural and synthetic elongate materials that may or may not contribute to mesothelioma development in the lung. While the FPP was originally developed to explain the critical importance of asbestos and synthetic vitreous fiber length, width, aspect ratio and biopersistence in mesothelioma development, there are a vast number of additional inhalable materials that need to be considered in terms of pathogenic features that may contribute to mesothelioma or lack thereof. Not only does the ability to exert more exact control over the length and biopersistence of HARNs confirm the tenets of the FPP, but could be studied by implementating more appropriate toxicological tools for SAR analysis.

Endosteal plating for the treatment of malunions and nonunions of distal femur fractures.

Purpose: To describe the surgical technique and the outcome of a case series of nonunion and malunion of distal femur fractures treated with an endosteal medial plate combined with a lateral locking plate and with autogenous bone grafting.

Methods: We retrospectively analyzed a series of patients with malunion or nonunion of the distal femur treated with a medial endosteal plate in combination with a lateral locking plate, in a period between January 2011 and December 2019, Database from chart review was obtained including all the clinical relevant available baseline data (demographics, type of fracture, mechanism of injury, time from injury to surgery, number of previous surgical procedures, type of bone graft, and type of lateral plate). Time to bone healing, limb alignment at follow-up and complications were documented.

Cluster-randomized trials of cancer screening interventions: Has use of appropriate statistical methods increased over time?

Background: In a cluster randomized trial, groups of individuals (e.g., clinics, schools) are randomized to conditions.

Viewing Readiness-for-Residency through Binoculars: Mapping Competency-Based Assessments to the AAMC's 13 Core Entrustable Professional Activities (EPAs).

: The construct being assessed is readiness-for-residency of graduating medical students, as measured through two assessment frameworks. : Readiness-for-residency of near-graduate medical students should be but is not consistently assessed. To address this, the Association of American Medical Colleges (AAMC), in 2014, identified and described 13 core Entrustable Professional Activities (EPAs), which are tasks that all residents should be able to perform unsupervised upon entering residency.

Atherosclerosis: Recent developments.

Atherosclerosis is an inflammatory disease of the large arteries that is the major cause of cardiovascular disease (CVD) and stroke. Here, we review the current understanding of the molecular, cellular, genetic, and environmental contributions to atherosclerosis, from both individual pathway and systems perspectives. We place an emphasis on recent developments, some of which have yielded unexpected biology, including previously unknown heterogeneity of inflammatory and smooth muscle cells in atherosclerotic lesions, roles for senescence and clonal hematopoiesis, and links to the gut microbiome.

Inhibition of microbiota-dependent TMAO production attenuates chronic kidney disease in mice.

Patients with chronic kidney disease (CKD) have elevated circulating levels of trimethylamine N-oxide (TMAO), a metabolite derived from gut microbes and associated with cardiovascular diseases. High circulating levels of TMAO and its dietary precursor, choline, predict increased risk for development of CKD in apparently healthy subjects, and studies in mice fed TMAO or choline suggest that TMAO can contribute to kidney impairment and renal fibrosis. Here we examined the interactions between TMAO, kidney disease, and cardiovascular disease in mouse models.

Attaining interprofessional competencies by connecting oral health to overall health.

Purpose: The purpose of this study was to evaluate the effectiveness of an annual oral-systemic health interprofessional education (IPE) clinical simulation and case study experience with nurse practitioner/midwifery (NP/MW), dental (DDS), medical (MD), and pharmacy (PharmD) students.

Methods: The Interprofessional Collaborative Competency Attainment Scale (ICCAS) was used to measure students' self-reported attainment of interprofessional competencies before and after the IPE experience. Pre- and post-test surveys were completed by NP/MW, DDS, MD, and PharmD student cohorts from 2017 to 2019.

Transcriptome Profiling of Human Monocyte-Derived Macrophages Upon CCL2 Neutralization Reveals an Association Between Activation of Innate Immune Pathways and Restriction of HIV-1 Gene Expression.

Macrophages are key targets of human immunodeficiency virus type 1 (HIV-1) infection and main producers of the proinflammatory chemokine CC chemokine ligand 2 (CCL2), whose expression is induced by HIV-1 both and . We previously found that CCL2 neutralization in monocyte-derived macrophages (MDMs) strongly inhibited HIV-1 replication affecting post-entry steps of the viral life cycle. Here, we used RNA-sequencing to deeply characterize the cellular factors and pathways modulated by CCL2 blocking in MDMs and involved in HIV-1 replication restriction.
