Phase 1 dose-escalation trial evaluating a group 2 influenza hemagglutinin stabilized stem nanoparticle vaccine.

The relative conservation of the influenza hemagglutinin (HA) stem compared to that of the immunodominant HA head makes the HA stem an attractive target for broadly protective influenza vaccines. Here we report the first-in-human, dose-escalation, open-label trial (NCT04579250) evaluating an unadjuvanted group 2 stabilized stem ferritin nanoparticle vaccine based on the H10 A/Jiangxi-Donghu/346/2013 influenza HA, H10ssF, in healthy adults. Participants received a single 20 mcg dose (n = 3) or two 60 mcg doses 16 weeks apart (n = 22).

Cost of chiropractic versus medical management of adults with spine-related musculoskeletal pain: a systematic review.

Background: The cost of spine-related pain in the United States is estimated at $134.5 billion. Spinal pain patients have multiple options when choosing healthcare providers, resulting in variable costs.

Urine-based multi-omic comparative analysis of COVID-19 and bacterial sepsis-induced ARDS.

Background: Acute respiratory distress syndrome (ARDS), a life-threatening condition during critical illness, is a common complication of COVID-19. It can originate from various disease etiologies, including severe infections, major injury, or inhalation of irritants. ARDS poses substantial clinical challenges due to a lack of etiology-specific therapies, multisystem involvement, and heterogeneous, poor patient outcomes.

Comparison of a Target Trial Emulation Framework vs Cox Regression to Estimate the Association of Corticosteroids With COVID-19 Mortality.

Importance: Communication and adoption of modern study design and analytical techniques is of high importance for the improvement of clinical research from observational data.

Objective: To compare a modern method for statistical inference, including a target trial emulation framework and doubly robust estimation, with approaches common in the clinical literature, such as Cox proportional hazards models.

Design, Setting, And Participants: This retrospective cohort study used longitudinal electronic health record data for outcomes at 28-days from time of hospitalization within a multicenter New York, New York, hospital system.

Multi-omic comparative analysis of COVID-19 and bacterial sepsis-induced ARDS.

Background: Acute respiratory distress syndrome (ARDS), a life-threatening condition characterized by hypoxemia and poor lung compliance, is associated with high mortality. ARDS induced by COVID-19 has similar clinical presentations and pathological manifestations as non-COVID-19 ARDS. However, COVID-19 ARDS is associated with a more protracted inflammatory respiratory failure compared to traditional ARDS.

The Role of Glutathione Reductase in Influenza Infection.

Influenza infection induces lung epithelial cell injury via programmed cell death. Glutathione, a potent antioxidant, has been reported to be associated with influenza infection. We hypothesized that lung epithelial cell death during influenza infection is regulated by glutathione metabolism.

Comparison of a Target Trial Emulation Framework to Cox Regression to Estimate the Effect of Corticosteroids on COVID-19 Mortality.

Importance: Communication and adoption of modern study design and analytical techniques is of high importance for the improvement of clinical research from observational data.

Objective: To compare (1) a modern method for causal inference including a target trial emulation framework and doubly robust estimation to (2) approaches common in the clinical literature such as Cox proportional hazards models. To do this, we estimate the effect of corticosteroids on mortality for moderate-to-severe coronavirus disease 2019 (COVID-19) patients.

Identification of Robust Protein Associations With COVID-19 Disease Based on Five Clinical Studies.

Multiple studies have investigated the role of blood circulating proteins in COVID-19 disease using the Olink affinity proteomics platform. However, study inclusion criteria and sample collection conditions varied between studies, leading to sometimes incongruent associations. To identify the most robust protein markers of the disease and the underlying pathways that are relevant under all conditions, it is essential to identify proteins that replicate most widely.

The Role of Chiropractic Care in Providing Health Promotion and Clinical Preventive Services for Adult Patients with Musculoskeletal Pain: A Clinical Practice Guideline.

To develop evidence-based recommendations on best practices for delivery of clinical preventive services by chiropractors and to offer practical resources to empower provider applications in practice. Clinical practice guideline based on evidence-based recommendations of a panel of practitioners and experts on clinical preventive services. Synthesizing the results of a literature search for relevant clinical practice guidelines and systematic reviews, a multidisciplinary steering committee with training and experience in health promotion, clinical prevention, and/or evidence-based chiropractic practice drafted a set of recommendations.

Federal Employees' Compensation Act and Mandating the Use of X-ray for Chiropractic Management of Federal Employees: An Exploration of Concerns and a Call to Action.

Objective: The purpose of this article is to explore concerns regarding sections of the federal workers' compensation law that apply to the treatment and management of work-related injuries of federal employees by chiropractors, and to offer a call to action for change.

Discussion: A 1974 amendment to the Federal Employees' Compensation Act (FECA) stipulates that chiropractic services rendered to injured federal workers are reimbursable. However, the only reimbursable chiropractic treatment is "manual manipulation of the spine to correct a subluxation as demonstrated by X-ray to exist.

Best-Practice Recommendations for Chiropractic Management of Patients With Neck Pain.

Objective: The purpose of this study was to develop best-practice recommendations for chiropractic management of adults with neck pain.

Methods: A steering committee of experts in chiropractic practice, education, and research drafted a set of recommendations based on the most current relevant clinical practice guidelines. Additional supportive literature was identified through targeted searches conducted by a health sciences librarian.

Protection against malaria at 1 year and immune correlates following PfSPZ vaccination.

An attenuated Plasmodium falciparum (Pf) sporozoite (SPZ) vaccine, PfSPZ Vaccine, is highly protective against controlled human malaria infection (CHMI) 3 weeks after immunization, but the durability of protection is unknown. We assessed how vaccine dosage, regimen, and route of administration affected durable protection in malaria-naive adults. After four intravenous immunizations with 2.

Clinical Practice Guideline: Chiropractic Care for Low Back Pain.

Objective: The purpose of this article is to provide an update of a previously published evidence-based practice guideline on chiropractic management of low back pain.

Methods: This project updated and combined 3 previous guidelines. A systematic review of articles published between October 2009 through February 2014 was conducted to update the literature published since the previous Council on Chiropractic Guidelines and Practice Parameters (CCGPP) guideline was developed.

Indoor inertial waypoint navigation for the blind.

Indoor navigation technology is needed to support seamless mobility for the visually impaired. This paper describes the construction and evaluation of an inertial dead reckoning navigation system that provides real-time auditory guidance along mapped routes. Inertial dead reckoning is a navigation technique coupling step counting together with heading estimation to compute changes in position at each step.

Chiropractic management of low back disorders: report from a consensus process.

Objective: Although a number of guidelines addressing manipulation, an important component of chiropractic professional care, exist, none to date have incorporated a broad-based consensus of chiropractic research and clinical experts representing mainstream chiropractic practice into a practical document designed to provide standardized parameters of care. The purpose of this project was to develop such a document.

Methods: Development of the document began with seed materials, from which seed statements were distilled.
