Toxicology of alcohol-based hand rubs formulated with technical-grade ethanol.

Alcohol-based hand rubs (ABHRs) formulated with technical-grade ethanol were temporarily permitted in Canada and the U.S beginning April 2020 to meet the current demand due to COVID-19. ABHRs formulated with technical-grade ethanol are low risk for general use. In this review, we discuss the toxicity of common contaminants found in technical-grade ethanol, as well as contaminants that may have been introduced into the products during formulation and packaging of ABHRs. Although primary route of exposure is via dermal absorption and inhalation, there have been reported elevated concerns regarding to ingestion of ABHRs. Overall, the highest risks were associated with methanol (for its toxicity), ethyl acetate (skin defattening), and acetaldehyde (carcinogenic and teratogenic). For these reasons Health Canada and the United States Food and Drug Administration have issued recalls on products containing some of these contaminants. More vigilant policing by regulatory agencies and general product users are required to ensure compliance, safety, and efficacy of these new products, as demand continue to rise during this unprecedented pandemic.

Underutilisation of EPaCCS (Electronic Palliative Care Coordination Systems) in end-of life-care: a cross-sectional study.

OBJECTIVE: To support greater personalisation of end-of-life care, Electronic Palliative Care Coordination Systems (EPaCCS) have been implemented across England. Here, we describe patient factors associated with dying with an EPaCCS record and explore the association between having an EPaCCS record with cause and place of death. METHOD: This is a cross-sectional study using routinely collected data. Data were extracted from primary care records in 20 of 86 general practices within one Clinical Commissioning Group in England. All deaths (n=1723) recorded between 22 February 2018 and 21 February 2019 were included to determine whether the deceased patient had an EPaCCS record at the time of death, a range of demographic factors, place of death and cause of death. RESULTS: Only 18% of the sample died with an EPaCCS record, and people who died of a non-cancer cause were less likely to have an EPaCCS record than those who died of cancer (OR=0.41; 95% CI 0.31 to 0.55). Adjusting for patient demographic factors and cause of death, having an EPaCCS record was strongly associated with dying in the community (OR=5.10; 95% CI 3.70 to 7.03). CONCLUSIONS: A small proportion of this sample died with an EPaCCS record, despite evidence of an association with dying in the community.

Impact of electronic palliative care coordination systems (EPaCCS) on care at the end of life across multiple care sectors, in one clinical commissioning group area, in England: a realist evaluation protocol.

INTRODUCTION: Electronic palliative care coordination systems (EPaCCS) aim to support people approaching the end of life (EOL) to receive consistent care, according to their wishes, that is coordinated effectively across multiple care sectors. They are in use across the UK although empirical evidence into their effectiveness is poor. This paper presents a protocol of a mixed-methods study, to understand how, and by whom, EPaCCS are being used and whether EPaCCS are enabling Healthcare Professionals (HCPs) to coordinate patients' EOL care. METHODS AND ANALYSIS: This is a mixed-methods study, carried out within a realist paradigm, to evaluate the impact of an EPaCCS on EOL care as provided by a Clinical Commissioning Group (CCG) in England. This study has two aims: (1) Describe the socio-demographic characteristics of patients who die with an EPaCCS record, their underlying cause of death and place of death and compare these with patients who die without an EPaCCS record. (2) Explore the impact of an EPaCCS on the experience of receiving EOL care for patients and their carers, and understand HCPs' views and experiences of utilising an EPaCCS to coordinate care for their patients. The study will be conducted in five phases: (1) development of the initial programme theory; (2) focus group with CCG stakeholder board; (3) individual interviews with HCPs, patients, current and bereaved carers; (4) retrospective cohort study of routinely collected data on EPaCCS usage and (5) data analysis and synthesis of study findings. ETHICS AND DISSEMINATION: The study has been approved by National Health Service South West-Frenchay Research Ethics Committee (REC reference number: 18/SW/0198). Findings will be published in a wide range of outputs targeted at key audiences.

Impact of emergency hospital admissions on patterns of primary care prescribing: a retrospective cohort analysis of electronic records in England.

BACKGROUND: Little is known about the impact of hospitalisation on prescribing in UK clinical practice. AIM: To investigate whether an emergency hospital admission drives increases in polypharmacy and potentially inappropriate prescriptions (PIPs). DESIGN AND SETTING: A retrospective cohort analysis set in primary and secondary care in England. METHOD: Changes in number of prescriptions and PIPs following an emergency hospital admission in 2014 (at admission and 4 weeks post-discharge), and 6 months post-discharge were calculated among 37 761 adult patients. Regression models were used to investigate changes in prescribing following an admission. RESULTS: Emergency attendees surviving 6 months (N = 32 657) had a mean of 4.4 (standard deviation [SD] = 4.6) prescriptions before admission, and a mean of 4.7 (SD = 4.7; P<0.001) 4 weeks after discharge. Small increases (<0.5) in the number of prescriptions at 4 weeks were observed across most hospital specialties, except for surgery (-0.02; SD = 0.65) and cardiology (2.1; SD = 2.6). The amount of PIPs increased after hospitalisation; 4.0% of patients had ≥1 PIP immediately before pre-admission, increasing to 8.0% 4 weeks post-discharge. Across hospital specialties, increases in the proportion of patients with a PIP ranged from 2.1% in obstetrics and gynaecology to 8.0% in cardiology. Patients were, on average, prescribed fewer medicines at 6 months compared with 4 weeks post-discharge (mean = 4.1; SD = 4.6; P<0.001). PIPs decreased to 5.4% (n = 1751) of patients. CONCLUSION: Perceptions that hospitalisation is a consistent factor driving rises in polypharmacy are unfounded. Increases in prescribing post-hospitalisation reflect appropriate clinical response to acute illness, whereas decreases are more likely in patients who are multimorbid, reflecting a focus on deprescribing and medicines optimisation in these individuals. Increases in PIPs remain a concern.

[1-9-NαC]-Linusorb B3 (Cyclo-linopeptide A) dimethyl sulfoxide monosolvate.

Crystals of the dimethyl sulfoxide (DMSO) solvate of [1-9-NαC]-linusorb B3 (Cyclo-linopeptide A; CLP-A; C57H84N9O9·C2H6OS), a cyclic polypeptide were obtained following peptide extraction and purification from flaxseed oil. There are four intramolecular N-H⋯O hydrogen bonds. In the crystal, the mol-ecules are linked in chains along the a axis by N-H⋯O hydrogen bonds. Each DMSO O atom accepts a hydrogen bond from an NH group at the Phe6 location in the CLP-A mol-ecule.

Barriers to GPs identifying patients at the end-of-life and discussions about their care: a qualitative study.

BACKGROUND: Identification of patients at the end-of-life is the first step in care planning and many general practices have Palliative Care Registers. There is evidence that these largely comprise patients with cancer diagnoses, but little is known about the identification process. OBJECTIVE: To explore the barriers that hinder GPs from identifying and registering patients on Palliative Care Registers. METHODS: An exploratory qualitative approach was undertaken using semi-structured interviews with GPs in South West England. GPs were asked about their experiences of identifying, registering and discussing end-of-life care with patients. Interviews were audio recorded, transcribed and analysed thematically. RESULTS: Most practices had a Palliative Care Register, which were mainly composed of patients with cancer. They reported identifying non-malignant patients at the end-of-life as challenging and were reluctant to include frail or elderly patients due to resource implications. GPs described rarely using prognostication tools to identify patients and conveyed that poor communication between secondary and primary care made prognostication difficult. GPs also detailed challenges around talking to patients about end-of-life care. CONCLUSIONS: Palliative Care Registers are widely used by GPs for patients with malignant diagnoses, but seldom for other patients. The findings from our study suggest that this arises because GPs find prognosticating for patients with non-malignant disease more challenging. GPs would value better communication from secondary care, tools for prognostication and training in speaking with patients at the end-of-life enabling them to better identify non-malignant patients at the end-of-life.

Radiation capture and conversion efficiencies of Miscanthus sacchariflorus, M. sinensis and their naturally occurring hybrid M. × giganteus.

Miscanthus is a rhizomatous C4 grass of great interest as a biofuel crop because it has the potential to produce high yields over a wide geographical area with low agricultural inputs on marginal land less suitable for food production. At the moment, a clonal interspecific hybrid Miscanthus × giganteus is the most widely cultivated and studied in Europe and the United States, but breeding programmes are developing newer more productive varieties. Here, we quantified the physiological processes relating to whole season yield in a replicated plot trial in Wales, UK. Light capture and conversion efficiency were parameterized for four carefully selected genotypes (M. sinensis, M. sacchariflorus and Miscanthus × giganteus). Differences in the canopy architecture in mature stands as measured by the extinction coefficient (k) were small (0.55-0.65). Sensitivity analysis on a mathematical model of Miscanthus was performed to quantify the accumulative intercepted photosynthetically active radiation (iPAR) in the growing season using (i) k, (ii) variation in the thermal responses of leaf expansion rate, (iii) base temperature for degree days and (iv) date start of canopy expansion. A 10% increase in k or leaf area per degree day both had a minimal effect on iPAR (3%). Decreasing base temperature from 10 to 9 °C gave an 8% increase in iPAR. If the starting date for canopy expansion was the same as shoot emergence date, then the iPAR increases by 12.5%. In M. × giganteus, the whole season above ground and total (including below ground) radiation-use efficiency (RUE) ranged from 45% to 37% higher than the noninterspecific hybrid genotypes. The greater yields in the interspecific hybrid M. × giganteus are explained by the higher RUE and not by differences in iPAR or partitioning effects. Studying the mechanisms underlying this complex trait could have wide benefits for both fuel and food production.

Towards improving diagnosis of memory loss in general practice: TIMeLi diagnostic test accuracy study protocol.

BACKGROUND: People with cognitive problems, and their families, report distress and uncertainty whilst undergoing evaluation for dementia and perceive that traditional diagnostic evaluation in secondary care is insufficiently patient centred. The James Lind Alliance has prioritised research to investigate the role of primary care in supporting a more effective diagnostic pathway, and the topic is also of interest to health commissioners. However, there are very few studies that investigate the accuracy of diagnostic tests for dementia in primary care. METHODS: We will conduct a prospective diagnostic test accuracy study to evaluate the accuracy of a range of simple tests for diagnosing all-cause-dementia in symptomatic people aged over 70 years who have consulted with their general practitioner (GP). We will invite eligible people to attend a research clinic where they will undergo a range of index tests that a GP could perform in the surgery and also be assessed by a specialist in memory disorders at the same appointment. Participating GPs will request neuroimaging and blood tests and otherwise manage patients in line with their usual clinical practice. The reference standard will be the consensus judgement of three experts (neurologist, psychiatrist and geriatrician) based on information from the specialist assessment, GP records and investigations, but not including items in the index test battery. The target condition will be all-cause dementia but we will also investigate diagnostic accuracy for sub-types where possible. We will use qualitative interviews with patients and focus groups with clinicians to help us understand the acceptability and feasibility of diagnosing dementia in primary care using the tests that we are investigating. DISCUSSION: Our results will help clinicians decide on which tests to perform in someone where there is concern about possible dementia and inform commissioning of diagnostic pathways.

"Sometimes we can't fix things": a qualitative study of health care professionals' perceptions of end of life care for patients with heart failure.

BACKGROUND: Although heart failure has a worse prognosis than some cancers, patients often have restricted access to well-developed end of life (EoL) models of care. Studies show that patients with advanced heart failure may have a poor understanding of their condition and its outcome and, therefore, miss opportunities to discuss their wishes for EoL care and preferred place of death. We aimed to explore the perceptions and experiences of health care professionals (HCPs) working with patients with heart failure around EoL care. METHODS: A qualitative in-depth interview study nested in a wider ethnographic study of unplanned admissions in patients with heart failure (HoldFAST). We interviewed 24 HCPs across primary, secondary and community care in three locations in England, UK - the Midlands, South Central and South West. RESULTS: The study revealed three issues impacting on EoL care for heart failure patients. Firstly, HCPs discussed approaches to communicating with patients about death and highlighted the challenges involved. HCPs would like to have conversations with patients and families about death and dying but are aware that patient preferences are not easy to predict. Secondly, professionals acknowledged difficulties recognising when patients have reached the end of their life. Lack of communication between patients and professionals can result in situations where inappropriate treatment takes place at the end of patients' lives. Thirdly, HCPs discussed the struggle to find alternatives to hospital admission for patients at the end of their life. Patients may be hospitalised because of a lack of planning which would enable them to die at home, if they so wished. CONCLUSIONS: The HCPs regarded opportunities for patients with heart failure to have ongoing discussions about their EoL care with clinicians they know as essential. These key professionals can help co-ordinate care and support in the terminal phase of the condition. Links between heart failure teams and specialist palliative care services appear to benefit patients, and further sharing of expertise between teams is recommended. Further research is needed to develop prognostic models to indicate when a transition to palliation is required and to evaluate specialist palliative care services where heart failure patients are included.

Impact of the Marie Curie Cancer Care Delivering Choice Programme in Somerset and North Somerset on place of death and hospital usage: a retrospective cohort study.

OBJECTIVES: The Marie Curie Cancer Care Delivering Choice Programme (DCP) aims to help palliative patients be cared for in their place of choice. In this study, new palliative care services delivered in two counties in England included end-of-life care coordination centres, an out-of-hours telephone line and discharge in-reach nurses. The study aimed to investigate the impact of DCP on place of death and hospital usage (emergency department (ED) and admissions). METHODS: Retrospective cohort of all eligible palliative patients who died over a 6-month period in two counties (n=3594). Participants were those who died of conditions considered to be eligible for end-of-life care, as defined by the Public Health England National End of Life Care Intelligence Network. The sample included people who did and did not access DCP services. DCP service, hospital admission and ED use data, demographic and death data were collected on all eligible participants. Data were analysed using descriptive statistics and logistic regression. RESULTS: After adjusting for potential confounders, those using Delivering Choice were at least 30% less likely to die in hospital or have an emergency hospital admission or ED visit in the last 30 or 7 days of life than those who did not. CONCLUSIONS: Recipients of DCP services were less likely to die in or use hospital services. Those considering new ways of providing end-of-life care could explore the possibility of adopting similar services and evaluating the outcomes from patient, carer and system perspectives.

What works in 'real life' to facilitate home deaths and fewer hospital admissions for those at end of life?: results from a realist evaluation of new palliative care services in two English counties.

BACKGROUND: WE EVALUATED END OF LIFE CARE SERVICES IN TWO ENGLISH COUNTIES INCLUDING: coordination centres, telephone advice line, 'Discharge in Reach' nurses, a specialist community personal care team and community nurse educators. Elsewhere, we published findings detailing high family carer satisfaction and fewer hospital admissions, Accident and Emergency attendances and hospital deaths for service users compared to controls. The aim of this paper is to discuss what contributed to those outcomes. METHODS: Using realist evaluation, data collection included documentation (e.g. referral databases), 15 observations of services and interviews with 43 family carers and 105 professionals. Data were analysed using framework analysis, applying realist evaluation concepts. Findings were discussed at successive team meetings and further data was collected until team consensus was reached. RESULTS: Services 'worked' primarily for those with cancer with 'fast track' funding who were close to death. Factors contributing to success included services staffed with experienced palliative care professionals with dedicated (and sufficient) time for difficult conversations with family carers, patients and/or clinical colleagues about death and the practicalities of caring for the dying. Using their formal and informal knowledge of the local healthcare system, they accessed community resources to support homecare and delivered excellent services. This engendered confidence and reassurance for staff, family carers and patients, possibly contributing to less hospital admissions and A&E attendances and more home deaths. CONCLUSIONS: With demand for 24-hour end of life care growing and care provision fragmented across health and social care boundaries, services like these that cut across organisational sectors may become more important. They offer an overview to help navigate those desiring a home death through the system.

Pharmacist-led interventions to reduce unplanned admissions for older people: a systematic review and meta-analysis of randomised controlled trials.

PURPOSE: medication problems are thought to cause between 10 and 30% of all hospital admissions in older people. This systematic review aimed to evaluate the effectiveness of interventions led by hospital or community pharmacists in reducing unplanned hospital admissions for older people. METHODS: eighteen databases were searched with a customised search strategy. Relevant websites and reference lists of included trials were checked. Randomised controlled trials were included that evaluated pharmacist-led interventions compared with usual care, with unplanned admissions or readmissions as an outcome. Two authors independently extracted data and assessed methodological quality. RESULTS: twenty-seven randomised controlled trials (RCTs) were identified; seven trials were excluded. The 20 included trials comprised 16 for older people and 4 for older people with heart failure. Interventions led by hospital pharmacists (seven trials) or community pharmacists (nine trials) did not reduce unplanned admissions in the older population (risk ratios 0.97 95% CI: 0.88, 1.07; 1.07 95% CI: 0.96, 1.20). Three trials in older people with heart failure showed that interventions delivered by a hospital pharmacist reduced the relative risk of admissions. However, these trials were heterogeneous in intensity and duration of follow-up. One trial had a high risk of bias. CONCLUSIONS: evidence from three randomised controlled trials suggests that interventions led by hospital pharmacists reduce unplanned hospital admissions in older patients with heart failure, although these trials were heterogeneous. Data from 16 trials do not support the concept that interventions led by hospital or community pharmacists for the general older population reduces unplanned admissions.

Emergency respiratory admissions: influence of practice, population and hospital factors.

OBJECTIVE: To determine the influence of population, hospital and general practice characteristics on practice admission rates for asthma and chronic obstructive pulmonary disease (COPD) in England. METHODS: Cross sectional study using Hospital Episode Statistics (HES), routine population data and primary care data. Admissions for all general practices in England during 2005-06, adjusted for age and sex composition of practice population. Univariable analysis of population, practice and hospital care provision variables, including prevalence and quality data. Significant factors included in multiple regression Poisson model. RESULTS: Admissions from 8169 practices were included. Risk of admission for each condition increased with deprivation, prevalence and smoking. Admission rates were higher in urban than rural practices. Hospital bed availability and distance to the nearest emergency department were also significantly associated with risk of admission. The associations with practice factors including practice size and quality markers varied across conditions. CONCLUSIONS: Practice population, geographic and hospital supply factors are consistently associated with asthma and COPD admissions. Higher smoking rates among such patients in a practice are associated with higher admission rates. There is little evidence from this study that other modifiable general practice factors are important in influencing admission rates.

Acne vulgaris.

INTRODUCTION: Acne vulgaris affects over 80% of teenagers, and persists beyond the age of 25 years in 3% of men and 12% of women. Typical lesions of acne include comedones, inflammatory papules, and pustules. Nodules and cysts occur in more severe acne and can cause scarring and psychological distress. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical question: What are the effects of topical and oral treatments in people with acne vulgaris? We searched: Medline, Embase, The Cochrane Library, and other important databases up to February 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). RESULTS: We found 69 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS: In this systematic review we present information relating to the effectiveness and safety of the following interventions: topical treatments (adapalene, azelaic acid, benzoyl peroxide, clindamycin, erythromycin [alone or plus zinc]; isotretinoin, tetracycline, tretinoin); and oral treatments (doxycycline, isotretinoin, lymecycline, minocycline, oxytetracycline, tetracycline).

A pilot randomized, controlled trial of treatment for painful arc of the shoulder.

There is a lack of evidence about the efficacy of routinely used interventions in shoulder pain, such as corticosteroid injection and physiotherapy. This pilot study was set up to assess the feasibility of a larger, randomized controlled trial. Patients with the clinical presentation of a painful arc of less than 6 months' duration were recruited through their general practitioners. A total of 112 patients were randomized to 4 groups: control, physiotherapy, a course of subacromial steroid injections, or both physiotherapy and steroid injections. The primary outcome measure was the Oxford Shoulder Score (OSS). Follow-up was 18 weeks and by postal questionnaire at 1 year. No significant differences were found within groups between the OSS scores or the Physical Health total of the Medical Outcomes Study Short Form 36 (SF-36) Health Survey at the beginning and end of the trial or at 1 year. By analysis of covariance, no significant differences were found between treatment groups. Larger studies are needed. A power calculation from our data suggests recruitment of more than 800 patients would be required to achieve a 90% chance of a clinically significant difference being detected between these groups.
