HIV Prevention in Syringe Service Programs Since the Start of COVID-19: Where Do We Go From Here?

Purpose: This narrative review addresses post-2020, specific, complex challenges for use of and adherence to pre-exposure prophylaxis (PrEP) for HIV prevention among out-of-treatment people who use drugs (PWUD) at syringe services programs (SSPs).

Recent Findings: The COVID-19 pandemic and its associated changes to the provision of healthcare have significantly impacted HIV prevention, especially for PWUD. Through a synthesis of literature and clinical experience, we (1) characterize the operational changes imposed by the pandemic on SSPs that shaped the current HIV prevention landscape; (2) describe three levels of current challenges for PWUD, including consumer attitudes, non-medical and medical provider attitudes, and structural and scalability barriers; (3) characterize current models for PrEP in SSPs; and (4) offer practical recommendations for HIV prevention in harm reduction programs.

Quantification of Particle-Associated Viruses in Secondary Treated Wastewater Effluent.

Viruses can interact with a broad range of inorganic and organic particles in water and wastewater. These associations can protect viruses from inactivation by quenching chemical disinfectants or blocking ultraviolet light transmission, and a much higher dosage of disinfectants is required to inactivate particle-associated viruses than free viruses. There have been only few studies of the association of viruses with particles in wastewater, particularly in secondary treated effluent.

Time-restricted feeding reduces cardiovascular disease risk in obese mice.

Disrupted feeding and fasting cycles as well as chronic high fat diet (HFD)-induced obesity are associated with cardiovascular disease risk factors. We designed studies that determined whether two weeks of time-restricted feeding (TRF) intervention in mice fed a chronic HFD would reduce cardiovascular disease risk factors. Mice were fed a normal diet (ND; 10% fat) ad libitum or HFD (45% fat) for 18 weeks ad libitum to establish diet-induced obesity.

Sociodemographic Variables Associated with Self-reported Access to Mental Healthcare Among Brazilian Immigrant Women in the U.S.

Brazilians are a rapidly growing immigrant population in the United States (U.S.), yet little is known about their mental health and access to mental healthcare.

Civil Disobedience in Democratic Education.

The study's goal was to examine the tension between democratic school governance, requiring its participants to obey school rules, even though they might disagree with those rules, and personal responsibility, requiring the participants to act morally, in accordance with their conscience and their sense of what is right and makes sense for them, regardless of the democratic nature of the imposed school rules. This examination was based on three sources: 1) three Open Symposia with American and Russian democratic educationalists, 2) my review of the existing literature on civil disobedience and democratic education, and 3) my empirical study based on the interviews of participants of an American private democratic school, known as The Circle School, regarding their instances of civil disobedience. The three Open Symposia allowed me to develop a working definition of civil disobedience as a particular principled disobedience.

Content Validity of the Friedreich Ataxia Rating Scale in Patients with Spinocerebellar Ataxia.

Introduction: The Friedreich Ataxia Rating Scale-Activities of Daily Living (FARS-ADL) is a validated and highly utilized measure for evaluating patients with Friedreich Ataxia. While construct validity of FARS-ADL has been shown for spinocerebellar ataxia (SCA), content validity has not been established.

Methods: Individuals with SCA1 or SCA3 (n = 7) and healthcare professionals (HCPs) with SCA expertise (n = 8) participated in qualitative interviews evaluating the relevance, clarity, and clinical meaningfulness of FARS-ADL for assessment of individuals with SCA.

Association Between Nail Type and Aseptic Revision Risk After Cephalomedullary Nailing for Hip Fracture.

Background: Although the majority of intertrochanteric femoral fractures in the United States are now treated with cephalomedullary nailing, it remains uncertain whether differences in clinical performance by nail type exist. The purpose of this study was to compare the aseptic revision rates associated with the 3 most commonly utilized cephalomedullary nails in the United States today: the Gamma nail (Stryker), the INTERTAN (Smith+Nephew), and the Trochanteric Fixation Nail/Trochanteric Fixation Nail Advanced (TFN/TFNA; DePuy Synthes).

Methods: Using an integrated health-care system's hip fracture registry, patients ≥60 years of age who were treated with 1 of these 3 commonly used cephalomedullary nail devices were identified.

Classical cell cycle kinase limits tubulin polyglutamylation and cilium stability.

Tubulin polyglutamylation is essential for maintaining cilium stability and function, and defective tubulin polyglutamylation is associated with ciliopathies. However, the regulatory mechanism underlying proper axonemal polyglutamylation remains unclear. He et al.

Pharmacodynamic characterization and evaluation of oxidative stress effects of digitoxigenin derivatives on HeLa cells.

Cancer is a leading cause of death worldwide and its treatment is hampered by the lack of specificity and side effects of current drugs. Cardiotonic steroids (CTS) interact with Na/K-ATPase (NKA) and induce antineoplastic effects, but their narrow therapeutic window is key limiting factor. The synthesis of digitoxigenin derivatives with glycosidic unit modifications is a promising approach to develop more selective and effective antitumor agents.

Mutations disrupting the kinase domain of IKKα lead to immunodeficiency and immune dysregulation in humans.

IKKα, encoded by CHUK, is crucial in the non-canonical NF-κB pathway and part of the IKK complex activating the canonical pathway alongside IKKβ. The absence of IKKα causes fetal encasement syndrome in humans, fatal in utero, while an impaired IKKα-NIK interaction was reported in a single patient and causes combined immunodeficiency. Here, we describe compound heterozygous variants in the kinase domain of IKKα in a female patient with hypogammaglobulinemia, recurrent lung infections, and Hay-Wells syndrome-like features.

Comparing the Introduction and Implementation of Noninvasive Prenatal Testing (NIPT) in Japan, the Netherlands, and the United States: An Integrative Review.

Previous studies suggest that NIPT's implementation differed widely across countries but offer limited insight into what shaped these differences. To address this gap, we conducted an in-depth analysis of how NIPT was incorporated into prenatal care in the US, the Netherlands, and Japan-countries with similar economic status-to identify actionable lessons. We conducted an integrative literature review on the process of introducing and implementing NIPT, stakeholders' roles, documented considerations in the decision to introduce NIPT, implementation choices, and NIPT uptake.

Investigation of the Gas-Phase N + CHCN Reaction at Low Temperatures.

Rate coefficients for ion-polar-molecule reactions between acetonitrile molecules (CHCN) and nitrogen molecular ions (N), which are of importance to the upper atmospheric chemistry of Saturn's moon Titan, were measured for the first time at low translational temperatures. In the experiments, the reaction between sympathetically cooled N ions embedded in laser-cooled Ca Coulomb crystals and velocity-selected acetonitrile molecules generated using a wavy Stark velocity filter was studied to determine the reaction rate coefficients. Capture rate coefficients calculated by the Su-Chesnavich approach and by the perturbed rotational state theory considering the rotational state distribution of CHCN were compared to the experimental rate coefficients.

Porous Silicon on Paper: A Platform for Quantitative Rapid Diagnostic Tests.

Porous silicon (PSi) thin films on silicon substrates have been extensively investigated in the context of biosensing applications, particularly for achieving label-free optical detection of a wide range of analytes. However, mass transport challenges have made it difficult for these biosensors to achieve rapid response times and low detection limits. In this work, we introduce an approach for improving the efficiency of molecule transport in PSi by using open-ended PSi membranes atop paper substrates in a flow-through sensor scheme.

Panchromatic Absorption of Unsymmetrical Donor-Acceptor Dyes Based on a Meta-conjugated 1,3,5-Heteroaryltriazine Core.

Attachment of three different heterocycles with electron donor or acceptor character to a central 1,3,5-triazine core generates readily soluble side-chain free dyes with two displaying soft crystalline mesomorphism and one displaying a nematic liquid crystal phase as confirmed by polarized optical microscopy, calorimetry, gravimetric analysis, and powder X-ray diffraction. Equally intriguing is the dyes' relatively strong electronic communication between donor and acceptor subchromophores that are meta-conjugated to one another, which is experimentally observed as a broad intramolecular charge-transfer absorption that can extend over 100 nm past the most intense absorption event and is computationally confirmed through density functional theory (DFT) evaluations of the molecular ground- and excited-state properties. This molecular design permits the preparation of dyes with panchromatic absorption not just based on the additive absorption of individual subchromophores.

Tuning Fork Scanning Electrochemical Cell Microscopy for Resolving Morphological and Redox Properties of Single Ag Nanowires.

We report a Tuning Fork Scanning Electrochemical Cell Microscopy (TF-SECCM) technique for providing morphological and electrochemical information on single redox-active entities. This new operation configuration of SECCM utilizes an electrolyte-filled nanopipette tip mounted onto a tuning fork force sensor to obtain a precise tip-sample distance control and surface morphological mapping capabilities. Redox activities of regions of interest (ROIs) can be investigated by scanning electrode potential by moving the nanopipette to any target regions while maintaining the constant force engagement of the tip with the sample.

Control of the Phase Distribution in TMDs by Strain Engineering and Kirigami Techniques.

Materials exhibiting both metallic and semiconducting states, including two-dimensional transition metal dichalcogenides (TMDs), have numerous applications. We therefore investigate the effects of axial and shear strains on the phase energetics of pristine and striped TMDs using density functional theory and classical molecular dynamics simulations. We demonstrate that control of the phase distribution can be achieved by the integration of strain engineering and Kirigami techniques.
