Intervertebral Disc Magnetic Resonance Spectroscopy Changes After Spinal Manipulative Therapy for Lumbar Discogenic Pain.

This study investigates the use of magnetic resonance spectroscopy (MRS) to identify the intervertebral disc (IVD) as a pain generator, explore the pathophysiology of the biochemical and structural components of discogenic low back pain (DLBP), and present potential evidence of physiological responses to spinal manipulation therapy (SMT). A 29-year-old male presented with uncomplicated low back pain (LBP). The non-specific presentation and clinical examination findings were consistent with an initial working diagnosis of non-specific LBP with the clinician suspecting IVD as a likely pain generator.

Booster-free anti-retroviral therapy for persons living with HIV and multidrug resistance (B-Free): protocol for a multicentre, multistage, randomised, controlled, non-inferiority trial.

Introduction: Anti-retroviral therapy (ART) simplification strategies are needed for treatment-experienced people with HIV (PWH) and multidrug-resistant viruses. These individuals are commonly treated with boosted ART regimens and are thereby at risk for harmful drug-drug interactions (DDI). In this trial, we aim to assess the efficacy of the combination doravirine, dolutegravir and lamivudine (DOR/DTG/3TC) among people with a history of virological failure who receive boosted ART.

Formation of β-UO from UCl Salt Compositions under Oxygen Exposure.

Complementary X-ray absorption fine structure (XAFS) and Raman spectroscopy studies were conducted on various UCl concentrations in alkali chloride salt compositions. The samples were 5 mol % UCl in LiCl (S1), 5 mol % UCl in KCl (S2), 5 mol % UCl in LiCl-KCl eutectic (S4), 50 mol % UCl in KCl (S5), and 20 mol % UCl in KCl (S6) molar concentrations. Samples were heated to 800 °C and allowed to cool to room temperature with measurements performed at selected temperatures; the highest temperatures showed the most stability and will be primarily referenced for conclusions.

Hepatitis C Treatment and Behavioral Risk Among Men Who Have Sex With Men With HIV: Comparing Interferon and Direct-Acting Antiviral Eras.

Background: Little is known about the effect of hepatitis C virus (HCV) treatment on sexual risk behavior among men who have sex with men (MSM) with HIV by treatment type (interferon [IFN]-based vs direct-acting antiviral [DAA]-based).

Setting: MSM with HIV and recently acquired HCV infection enrolled in the MSM Observational Study of Acute Infection with hepatitis C (MOSAIC) cohort.

Methods: Using data from 2009 to 2018, we evaluated risk behavior through a validated HCV risk score (where ≥2 indicated high risk) and its individual risk behaviors.

Impact of morphology and oxygen vacancy content in Ni, Fe co-doped ceria for efficient electrocatalyst based water splitting.

Designing a highly efficient, low-cost, sustainable electrocatalyst for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) through water splitting is a current challenge for renewable energy technologies. This work presents a modified sol-gel route to prepare metal-ion(s) doped cerium oxide nanostructures as an efficient electrocatalyst for overall water splitting. Nickle (Ni) and iron (Fe) co-doping impacts the morphology in cerium oxide resulting in 5 nm nanoparticles with a mesoporous-like microstructure.

Real-world effectiveness and tolerability of switching to doravirine-based antiretroviral therapy in people with HIV: a nationwide, matched, prospective cohort study.

Background: Currently, real-world data on doravirine are scarce. In a national prospective cohort, we assessed the effectiveness and tolerability of switching to doravirine-based antiretroviral therapy (ART) in people with HIV.

Methods: We did a nationwide, matched, prospective cohort study of people with HIV without previous virological failure and stable for at least 12 months on non-doravirine-containing triple or dual ART switching to doravirine before Sept 1, 2020 (exposed group).

Immunogenicity of a bivalent BA.1 COVID-19 booster vaccine in people with HIV in the Netherlands.

Objective: We evaluated the immunogenicity of a bivalent BA.1 COVID-19 booster vaccine in people with HIV (PWH).

Design: Prospective observational cohort study.

De-simplifying antiretroviral therapy from a single-tablet to a two-tablet regimen: Acceptance, patient-reported outcomes, and cost savings in a multicentre study.

Background: Antiretroviral therapy (ART), which is increasingly used by people with HIV, accounts for significant care costs, particularly because of single-tablet regimens (STRs). This study explored de-simplification to a two-tablet regimen (TTR) for cost reduction. The objectives of this study were: (1) acceptance of de-simplification, (2) patient-reported outcomes, and (3) cost savings.

Cardiometabolic Differences in People Living with HIV Receiving Integrase Strand Transfer Inhibitors Compared to Non-nucleoside Reverse Transcriptase Inhibitors: Implications for Current ART Strategies.

In people living with HIV (PLHIV), integrase strand transfer inhibitors (INSTIs) are part of the first-line combination antiretroviral therapy (cART), while non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens are alternatives. Distinct cART regimens may variably influence the risk for non-AIDS comorbidities. We aimed to compare the metabolome and lipidome of INSTI and NNRTI-based regimens.

Negative impact of a health insurer-mandated de-simplification from a single-tablet regimen to a two-tablet regimen.

Objectives: Antiretroviral therapy (ART) accounts for a considerable proportion of HIV care expenses. In June 2021, a Dutch healthcare insurer implemented a mandatory policy to de-simplify branded RPV/TDF/FTC (Eviplera) into a two-tablet regimen containing rilpivirine (Edurant) and generic TDF/FTC as part of cost-saving measures. The objectives of this study were to evaluate the acceptance of this policy, the trends in ART dispensation, and cost developments.

When a Critically Ill Child is Oceans Away From a PICU: A Military Pediatric CCAT Mission.

A 4-year-old former 26-week premature male presented to the U.S. Naval Hospital Guam emergency department in respiratory failure secondary to human metapneumovirus requiring urgent intubation.

Does atrial fibrillation affect prognosis in hospitalised COVID-19 patients? A multicentre historical cohort study in the Netherlands.

Objectives: The aim of this multicentre COVID-PREDICT study (a nationwide observational cohort study that aims to better understand clinical course of COVID-19 and to predict which COVID-19 patients should receive which treatment and which type of care) was to determine the association between atrial fibrillation (AF) and mortality, intensive care unit (ICU) admission, complications and discharge destination in hospitalised COVID-19 patients.

Setting: Data from a historical cohort study in eight hospitals (both academic and non-academic) in the Netherlands between January 2020 and July 2021 were used in this study.

Participants: 3064 hospitalised COVID-19 patients >18 years old.

What is the aetiology of dysnatraemia in COVID-19 and how is this related to outcomes in patients admitted during earlier and later COVID-19 waves? A multicentre, retrospective observational study in 11 Dutch hospitals.

Objectives: To evaluate the relationship among dysnatraemia at hospital presentation and duration of admission, risk of intensive care unit (ICU) admission and all-cause mortality and to assess the underlying pathophysiological mechanism of hyponatraemia in patients with COVID-19. Our hypothesis is that both hyponatraemia and hypernatraemia at presentation are associated with adverse outcomes.

Design: Observational study.

Switching to Doravirine in cART-Experienced Patients: An Effective and Highly Tolerated Option With Substantial Cost Savings.

Background: Doravirine is a non-nucleoside reverse transcriptase inhibitor with demonstrated efficacy as a third agent in treatment-naive and treatment-experienced people living with HIV (PLWH) in registration studies. However, limited real-world data are available.

Methods: By searching electronic health care records, PLWH using doravirine-based regimens were selected with at least 1 year of follow-up after their first prescription.

Screening for Hepatitis C Virus Reinfection Using a Behaviour-Based Risk Score among Men Who Have Sex with Men with HIV: Results from a Case-Control Diagnostic Validation Study.

We assessed the predictive capacity of the HCV-MOSAIC risk score, originally developed for primary early HCV infection, as a screening tool for HCV reinfection in 103 men who have sex with men (MSM) with HIV using data from the MOSAIC cohort, including MSM with HIV/HCV-coinfection who became reinfected (cases, = 27) or not (controls, = 76) during follow-up. The overall predictive capacity of the score was assessed using the area under the receiver operating characteristic (AUROC) curve. The effects of covariates on the receiver operating characteristic (ROC) curve were assessed using parametric ROC regression.

Observation of Correlations between Spin and Transverse Momenta in Back-to-Back Dihadron Production at CLAS12.

We report the first measurements of deep inelastic scattering spin-dependent azimuthal asymmetries in back-to-back dihadron electroproduction in the deep inelastic scattering process. In this reaction, two hadrons are produced in opposite hemispheres along the z axis in the virtual photon-target nucleon center-of-mass frame, with the first hadron produced in the current-fragmentation region and the second in the target-fragmentation region. The data were taken with longitudinally polarized electron beams of 10.
