Home-Based Care Provider Perspectives on Care Refusal During the COVID-19 Pandemic.

Acute and chronic disease management continues to shift toward a health care in the home model, yet literature discussing continuity of home-based care services during public health emergencies, such as infectious disease pandemics, is scant. In the current study, we used semi-structured telephone interviews with 27 home-based care providers (HBCPs) from Medicare-certified home health care agencies located in eight U.S. counties to explore older adults' decision making around home-based care service continuation during the coronavirus disease 2019 (COVID-19) pandemic. Four themes emerged, including two related to older adults' decision making around refusal of in-home care and two related to HBCPs' responses to care refusals. Fear of COVID-19 infection motivated older adults to make care-related decisions that were incongruent with their health needs, including refusal of care in the home, despite receiving education from HBCPs. These data highlight a need for tools to help HBCPs better support patients through decision-making processes about care continuation during COVID-19 and future infectious disease pandemics.

Barriers and facilitators to providing home-based care in a pandemic: policy and practice implications.

OBJECTIVE: The purpose of this study is to describe the experiences of home-based care providers (HBCP)  in providing care to older adults during the pandemic in order to inform future disaster planning, including during pandemics. DESIGN: Qualitative inquiry using an abductive analytic approach. SETTING AND PARTICIPANTS: Home-based care providers in COVID-19 hotspots. METHODS: Telephone interviews were conducted with 27 participants (administrators, registered nurses and other members of the allied healthcare team), who provided in-home care during the pandemic in Medicare-certified home health agencies. Interviews focused on eliciting experiences from HBCP on challenges and successes in providing home-based care to older adults, including barriers to care and strategies employed to keep patients, and providers, safe in their homes during the pandemic. RESULTS: Data was distilled into four major themes that have potential policy and practice impact. These included disrupted aging-in-place resources, preparedness actions contributing to readiness for the pandemic, limited adaptability in administrative needs during the pandemic and challenges with unclear messaging from public health officials. CONCLUSIONS: Home-based care plays an essential role in maintaining the health of older adults in disaster contexts, including pandemics. Innovative solutions, informed by policy that generate evidence-based best practices to support HBCP are needed to reduce barriers and increase protective factors, in order to maintain continuity of care for this vulnerable population during disruptive events.

Selectivity and potential interference from phenolic compounds in chemiluminescence methods for the determination of synephrine.

Three recently reported chemiluminescence methods (based on reactions with alkaline luminol and hexacyanoferrate(III); acidic cerium(IV) and rhodamine B; and acidic permanganate with polyphosphates) for the determination of synephrine were re-evaluated in terms of their selectivity towards this analyte in comparison to other phenolic compounds. A fourth reagent system, acidic soluble manganese(IV) and formaldehyde, was also examined. Each set of reagents was sensitive towards synephrine (limits of detection were 3 x 10(-9), 5 x 10(-8), 1 x 10(-8) and 1 x 10(-8) mol/L, respectively) but also responded with numerous other phenolic compounds, including some that are present in citrus fruit extracts, dietary supplements and/or biological fluids. It is therefore recommended that the determination of synephrine in these matrices should incorporate physical separation of sample components (e.g. chromatography or electrophoresis). In more general terms, this study illustrates that accurate percentage recoveries for an analyte in spiked samples (without validation against another analytical method) are insufficient to confirm the analytical utility of new flow-injection analysis (FIA) procedures.

A guide to emollient therapy.

Although the benefits of emollient therapy have been widely acknowledged in dermatology treatments (Cork 1997), emollients have tended to be undervalued and under-used in general care and wound management. Healthy skin is an essential part of patient wellbeing, and emollient therapy is integral to the management of skin problems. The integration of tissue viability and dermatology services in the Plymouth Hospitals NHS Trust provided an opportunity to evaluate how and why emollient therapy is implemented. In practice, the authors have identified that healthcare practitioners need guidance and advice on emollient therapy to improve their care delivery. This article is based on the emollient therapy currently used in the authors' trust.

A Parent's Journey: Incorporating Principles of Palliative Care into Practice for Children with Chronic Neurologic Diseases.

Rather than in conflict or in competition with the curative model of care, pediatric palliative care is a complementary and transdisciplinary approach used to optimize medical care for children with complex medical conditions. It provides care to the whole child, including physical, mental, and spiritual dimensions, in addition to support for the family. Through the voice of a parent, the following case-based discussion demonstrates how the fundamentals of palliative care medicine, when instituted early in the course of disease, can assist parents and families with shared medical decision making, ultimately improving the quality of life for children with life-limiting illnesses. Pediatric neurologists, as subspecialists who provide medical care for children with chronic and complex conditions, should consider invoking the principles of palliative care early in the course of a disease process, either through applying general facets or, if available, through consultation with a specialty palliative care service.

STRAD pseudokinases regulate axogenesis and LKB1 stability.

BACKGROUND: Neuronal polarization is an essential step of morphogenesis and connectivity in the developing brain. The serine/threonine kinase LKB1 is a key regulator of cell polarity, metabolism, tumorigenesis, and is required for axon formation. It is allosterically regulated by two related and evolutionarily conserved pseudokinases, STe20-Related ADapters (STRADs) α and ß. The roles of STRADα and STRADß in the developing nervous system are not fully defined, nor is it known whether they serve distinct functions. RESULTS: We find that STRADα is highly spliced and appears to be the primal STRAD paralog. We report that each STRAD is sufficient for axogenesis and promoting cell survival in the developing cortex. We also reveal a reciprocal protein-stabilizing relationship in vivo between LKB1 and STRADα, whereby STRADα specifically maintains LKB1 protein levels via cytoplasmic compartmentalization. CONCLUSIONS: We demonstrate a novel role for STRADß in axogenesis and also show for the first time in vivo that STRADα, but not STRADß, is responsible for LKB1 protein stability.

Preliminary evaluation of monolithic column high-performance liquid chromatography with tris(2,2'-bipyridyl)ruthenium(II) chemiluminescence detection for the determination of quetiapine in human body fluids.

High-performance liquid chromatography (HPLC) with tris(2,2'-bipyridyl)ruthenium(II) chemiluminescence detection methodology is reported for the determination of the atypical antipsychotic drug quetiapine and the observation of its major active and inactive metabolites in human urine and serum. The method uses a monolithic chromatographic column allowing high flow rates of 3 mLmin(-1) enabling rapid quantification. Flow injection analysis (FIA) with tris(2,2'-bipyridyl)ruthenium(II) chemiluminescence detection and HPLC time of flight mass spectrometry (TOF-MS) were used for the determination of quetiapine in a pharmaceutical preparation to establish its suitability as a calibration standard. The limit of detection achieved with FIA was 2 x 10(-11) molL(-1) in simple aqueous solution. The limits of detection achieved with HPLC were 7 x 10(-8) and 2 x 10(-10) molL(-1) in urine and serum, respectively. The calibration range for FIA was between 5 x 10(-9) and 1 x 10(-6) molL(-1). The calibration ranges for HPLC were between 1 x 10(-7)-1 x 10(-4) and 1 x 10(-8)-1 x 10(-4) molL(-1) in urine and serum, respectively. The quetiapine concentrations in patient samples were found to be 3 x 10(-6) molL(-1) in urine and 7 x 10(-7) molL(-1) in serum. Without the need for preconcentration, the HPLC detection limits compared favourably with those in previously published methodologies. The metabolites were identified using HPLC-TOF-MS.

Manganese(III) and manganese(IV) as chemiluminescence reagents: a review.

Although potassium permanganate [Mn(VII)] has been used extensively as a chemiluminescence reagent for many decades, other manganese-based oxidants have only recently been explored for this purpose. There is strong evidence to suggest that, like permanganate, manganese(III) and manganese(IV) oxidants react with many molecules to produce an excited manganese(II) species that emits light. However, these reagents differ markedly in terms of selectivity, and possess characteristics that provide new avenues for detection, such as the immobilisation of solid manganese dioxide, the production of 'soluble' manganese(IV) nanoparticles, and the electrochemical generation of manganese(III). In this review we examine the emergence of these alternative manganese oxidants as chemiluminescence reagents.

Soluble manganese(IV) as a chemiluminescence reagent for the determination of opiate alkaloids, indoles and analytes of forensic interest.

We present the results of our investigations into the use of soluble manganese(IV) as a chemiluminescence reagent, which include a significantly faster method of preparation and a study on the effect of formaldehyde and orthophosphoric acid concentration on signal intensity. Chemiluminescence detection was applied to the determination of 16 analytes, including opiate alkaloids, indoles and analytes of forensic interest, using flow injection analysis methodology. The soluble manganese(IV) reagent was less selective than either acidic potassium permanganate or tris(2,2'-bipyridyl)ruthenium(III) and therefore provided a more universal chemiluminescence detection system for HPLC. A broad spectral distribution with a maximum at 730+/-5nm was observed for the reaction between the soluble manganese(IV) and a range of analytes, as well as the background emission from the reaction with the formaldehyde enhancer. This spectral distribution matches that reported for chemiluminescence reactions with acidic potassium permanganate, where a manganese(II) emitting species was elucidated. This provides further evidence that the emission evoked in reactions with soluble manganese(IV) also emanates from a manganese(II) species, and not bimolecular singlet oxygen as suggested by previous authors.
