We evaluated the use of the Product Enhanced Reverse Transcriptase (PERT) assay as a means of detecting virus in retroviral vectors products pseudotyped with Gibbon Ape Leukemia Virus (GALV) and Vesicular Stomatitis Virus G (VSVG) envelopes. PERT provides greater standardization than the S+/L- assay which has been used extensively in virus detection. A challenge is that PERT will also detect residual retroviral vectors as vector particles contain reverse transcriptase.

Introduction: This process evaluation was conducted in parallel to the randomised controlled feasibility trial of NIDUS-Professional, a manualised remote dementia training intervention for homecare workers (HCWs), delivered alongside an individualised intervention for clients living with dementia and their family carers (NIDUS-Family). The process evaluation reports on: (i) intervention reach, dose and fidelity; (ii) contexts influencing agency engagement and (iii) alignment of findings with theoretical assumptions about how the intervention might produce change.

Methods: We report proportions of eligible HCWs receiving any intervention (reach), number of sessions attended (dose; attending ≥4/6 main sessions was predefined as adhering), intervention fidelity and adherence of clients and carers to NIDUS-Family (attending all 6-8 planned sessions).

Article Synopsis
  • Antidepressants are commonly prescribed for depression, but not all patients respond well, prompting a need to investigate which characteristics might influence treatment effectiveness.
  • The PANDA trial compared the effectiveness of sertraline (an antidepressant) with a placebo in 655 primary care patients, examining 11 potential factors (like age, marital status, and family history) that could affect patients' responses to treatment.
  • The study found that only a patient's family history of depression showed any potential impact on treatment response, suggesting those without such a history may benefit more, while other factors had no significant influence, indicating a need for ongoing conversations about antidepressant options for all patients.

Article Synopsis
  • SSRIs like sertraline are common medications used to treat depression and anxiety, but researchers want to know how they affect thinking and emotions.
  • In a study with 655 participants, they tested how well people learned from their actions while taking either sertraline or a placebo.
  • The results showed that sertraline didn't improve task performance as expected, but some changes in learning from mistakes were linked to how people felt after treatment, though the initial predictions were not supported.

We describe the first implementation of a Josephson Traveling Wave Parametric Amplifier (JTWPA) in an axion dark matter search. The operation of the JTWPA for a period of about two weeks achieved sensitivity to axion-like particle dark matter with axion-photon couplings above 10-13 Ge V-1 over a narrow range of axion masses centered around 19.84 µeV by tuning the resonant frequency of the cavity over the frequency range of 4796.

Background: This paper investigates whether age of onset of depression, duration of the last episode, number of episodes, and residual symptoms of depression and anxiety are associated with depression relapse in primary care patients who have been on long-term maintenance antidepressant treatment and no longer meet ICD10 criteria for depression.

Methods: An observational cohort using data from ANTLER ( = 478), a double-blind placebo-controlled trial. The primary outcome was time to relapse using the retrospective CIS-R.

We report the first result of a direct search for a cosmic axion background (CaB)-a relativistic background of axions that is not dark matter-performed with the axion haloscope, the Axion Dark Matter eXperiment (ADMX). Conventional haloscope analyses search for a signal with a narrow bandwidth, as predicted for dark matter, whereas the CaB will be broad. We introduce a novel analysis strategy, which searches for a CaB induced daily modulation in the power measured by the haloscope.

Background: Therapeutic relational connection (TRC) in telehealth is a new concept that refers to the intentional use of relationship connection between health care providers and their patients as both parties work toward a therapeutic aim. It has been demonstrated that TRC positively affects patient-centered outcomes including adherence, self-management, and satisfaction with care. What is not known are best practices for establishing TRC during telehealth visits.

The University of Vermont's (UVM) Division of Neurosurgery is enshrined in a rich history of innovation and academic prowess, which have significantly contributed to making neurosurgery the field it is today. From humble beginnings, the department was started by one Raymond Madiford Peardon "Pete" Donaghy on a parenthetically watertight research budget amounting to $25 and shared space in a Quonset hut. Passion and commitment to progress, as well as an innate openness to collaboration, propelled Pete Donaghy, his colleagues, pupils, and successors to establish an exemplary center for treatment of neurosurgical disease, with multiple revolutionary accomplishments along the way.

Objectives: We are not aware of a simple and short structured measure that retrospectively assesses time to relapse for depression. We developed the retrospective Clinical Interview Schedule Revised (rCIS-R) to assess depression relapse in the previous 12 weeks, for use in a clinical trial of maintenance antidepressant treatment. We assessed test-retest reliability and construct validity in relation to a Global Rating Question (GRQ) about worsening mood, participants stopping their study medication and Patient Health Questionnaire (PHQ-9) scores.

Owing to the unique chemical and electronic properties arising from 3d-electrons, substitution with transition metal ions is one of the key routes for engineering new functionalities into materials. While this approach has been used extensively in complex metal oxide perovskites, metal halide perovskites have largely resisted facile isovalent substitution. In this work, it is demonstrated that the substitution of Co into the lattice of methylammonium lead triiodide imparts magnetic behavior to the material while maintaining photovoltaic performance at low concentrations.

Background: Antidepressants have been proposed to act via their influence on emotional processing. We investigated the effect of discontinuing maintenance antidepressant treatment on positive and negative self-referential recall and the association between self-referential recall and risk of relapse.

Methods: The ANTLER trial was a large ( = 478) pragmatic double-blind trial investigating the clinical effectiveness of long-term antidepressant treatment for preventing relapse in primary care patients.

Introduction: Most people living with dementia want to remain living in their own homes, and are supported to do so by family carers and homecare workers. There are concerns that homecare is often unable to meet the needs of this client group, with limited evidence regarding effective interventions to improve it for people living with dementia. We have developed a training and support programme for homecare workers (NIDUS-Professional) to be delivered alongside support sessions for people living with dementia and their family carers (NIDUS-Family).

The clinical impact of any therapy requires the product be safe and effective. Gammaretroviral vectors pose several unique risks, including inadvertent exposure to replication competent retrovirus (RCR) that can arise during vector manufacture. The US FDA has required patient monitoring for RCR, and the National Gene Vector Biorepository is an NIH resource that has assisted eligible investigators in meeting this requirement.

Peracetic acid (PAA) applied to whole poultry carcasses can reduce the number of Campylobacter, a leading cause of human gastroenteritis. However, previous modelling experiments indicated that Campylobacter survived in greater numbers when pre-treated with a thermal stress equivalent to poultry processing scalding prior to chilling with PAA than when subject to chilling with PAA only. To better understand how Campylobacter responds to PAA, proteomes of C.

Article Synopsis
  • Understanding the motivations and barriers faced by young, first-time blood donors is critical for improving retention rates.
  • A study with 508 young donors identified altruism as a key motivator and fear (such as fear of needles) as the primary barrier to donating.
  • Results indicated that while motivators didn't directly impact donation behavior, specific barriers significantly did, and variations were observed based on sex, race, and ethnicity.
