Palliatieve inpatients in general hospitals : a one day observational study in Belgium

Background: Hospital care plays a major role at the end-of-life. But little is known about the overall size and characteristics of the palliative inpatient population. The aim of our study was to analyse these aspects. Methods: We conducted a one-day observational study in 14 randomly selected Belgian hospitals. Patients who met the definition of palliative patients were identified as palliative. Then, information about their sociodemographic characteristics, diagnoses, prognosis, and care plan were recorded and analysed. Results: There were 2639 in-patients on the day of the study; 9.4% of them were identified as “palliative”. The mean age of the group was 72 years. The primary diagnosis was cancer in 51% of patients and the estimated life expectancy was shorter than 3 months in 33% of patients and longer than 1 year in 28% of patients. The professional caregivers expected for most of the patients (73%), that the treatment would improve patient comfort rather than prolong life. Antibiotics, transfusions, treatments specific to the pathology, and artificial nutrition were administered in 90%, 78%, 57% and 50% of the patients, respectively, but were generally given with a view to controlling the symptoms. Conclusions: This analysis presents a first national estimate of the palliative inpatient population. Our results confirm that hospitals play a major role at the end-of-life, with one out of ten inpatients identified as a “palliative” patient. These data also demonstrate the complexity of the palliative population and the substantial diversity of care that they can require

What Works to Improve and Manage Fecal Incontinence in Care Home Residents Living With Dementia? A Realist Synthesis of the Evidence.

The prevalence of fecal incontinence (FI) in care homes is estimated to range from 30% to 50%. There is limited evidence of what is effective in the reduction and management of FI in care homes. Using realist synthesis, 6 potential program theories of what should work were identified. These addressed clinician-led support, assessment, and review; the contribution of teaching and support for care home staff on how to reduce and manage FI; addressing the causes and prevention of constipation; how cognitive and physical capacity of the resident affects outcomes; how the potential for recovery, reduction, and management of FI is understood by those involved; and how the care of people living with dementia and FI is integral to the work patterns of the care home and its staff. Dementia was a known risk factor for fecal incontinence (FI), but how it affected uptake of different interventions or the dementia specific continence and toileting skills staff require, were not addressed in the literature. There was a lack of dementia-specific evidence on continence aids. Most care home residents with FI will be doubly incontinent; there is, therefore, limited value in focusing solely on FI or single causes, such as constipation. Medical and nursing support for continence care is an important resource, but it is unhelpful to create a distinction between what is continence care and what is personal or intimate care. Prompted toileting is an approach that may be particularly beneficial for some residents. Valuing the intimate and personal care work unqualified and junior staff provide to people living with dementia and reinforcement of good practice in ways that are meaningful to this workforce are important clinician-led activities. Providing dementia-sensitive continence care within the daily work routines of care homes is key to helping to reduce and manage FI for this population

SARS-CoV-2 susceptibility and COVID-19 disease severity are associated with genetic variants affecting gene expression in a variety of tissues

Variability in SARS-CoV-2 susceptibility and COVID-19 disease severity between individuals is partly due to genetic factors. Here, we identify 4 genomic loci with suggestive associations for SARS-CoV-2 susceptibility and 19 for COVID-19 disease severity. Four of these 23 loci likely have an ethnicity-specific component. Genome-wide association study (GWAS) signals in 11 loci colocalize with expression quantitative trait loci (eQTLs) associated with the expression of 20 genes in 62 tissues/cell types (range: 1:43 tissues/gene), including lung, brain, heart, muscle, and skin as well as the digestive system and immune system. We perform genetic fine mapping to compute 99% credible SNP sets, which identify 10 GWAS loci that have eight or fewer SNPs in the credible set, including three loci with one single likely causal SNP. Our study suggests that the diverse symptoms and disease severity of COVID-19 observed between individuals is associated with variants across the genome, affecting gene expression levels in a wide variety of tissue types

A health economic model to assess the cost-effectiveness of PEG IFN alpha-2a and ribavirin in patients with mild chronic hepatitis C.

According to the current guidelines, it is advised not to treat patients with mild chronic hepatitis C. However, discussions as to giving immediately a treatment (direct treatment) to these patients have started and the incremental cost-effectiveness ratio (ICER) of such strategy is still unknown. The aim of this study was to estimate, in the health care payer perspective, the ICER of a direct treatment of patients with mild chronic hepatitis C in comparison with the strategy of monitoring these patients and treat them when the disease will progress to the state of moderate chronic hepatitis. The treatment assessed was the current standard treatment composed of pegylated interferon alpha-2a and ribavirin. At the beginning of the study, patients were aged 45. Long-term economic and clinical outcomes over a 30-year period were predicted using a Markov simulation model. Data were obtained from published literature. Monte Carlo simulations were used to determine 95% confidence intervals of results. The ICER of a direct treatment with PEG IFN alpha-2a and ribavirin is 23,046 euro/QALY (CI 95% 3,882 euro-42,392 euro) for genotypes 1-4-5-6 and 4,631 euro/QALY (CI 95% 797 euro-7,881 euro) for genotypes 2-3. Sensitivity analysis shows that it is only in extreme circumstances related to the utilities that the ICER for genotypes 1-4-5-6 is unacceptably high for the society (>50,000 euro). Even though a direct treatment is more expensive, it gives the advantage of curing greater number of patients and of increasing quality-adjusted life-years (QALYs), implying that such strategy is generally cost-effective at a threshold of 50,000 euro/QALY

Predictors of clinicians' underuse of daily sedation interruption and sedation scales.

Purpose The purpose of the study is to identify predictors of underuse of sedation scales and daily sedation interruption (DSI). Methods We surveyed all physicians and seven nurses in every Belgian intensive care unit (ICU), addressing practices and perceptions on guideline recommendations. Underuse was defined for sedation scales as use less than 3× per day and for DSI as never using it. Classification trees and logistic regressions identified predictors of underuse. Results Underuse of sedation scales and DSI was found for 16.6% and 32.5% of clinicians, respectively. Strongest predictors of underuse of sedation scales were agreeing that using them daily takes much time and being a physician (rather than a nurse). Further predictors were confidence in their ability to measure sedation levels without using scales, for physicians, and nurse/ICU bed ratios less than 1.98, for nurses. The strongest predictor of underuse of DSI among physicians was the perception that DSI impairs patients’ comfort. Among nurses, lack of familiarity with DSI, region, and agreeing DSI should only be performed upon medical orders best predicted underuse. Conclusions Workload considerations hamper utilization of sedation scales. Poor familiarity, for nurses, and negative perception of impact on patients’ comfort, for physicians, both reduce DSI utilization. Targeting these obstacles is essential while designing quality improvement strategies to minimize sedative use

Quantification of cells expressing the thyrotropin receptor in extraocular muscles in thyroid associated orbitopathy.

BACKGROUND/AIM: Thyroid associated orbitopathy (TAO) and Graves' disease (GD) have an autoimmune pathogenesis, possibly related to the thyrotropin receptor (TSHR). The aim of this study was to determine whether TSHR immunoreactivity is correlated with disease severity or serum TSHR antibody (TRAB) levels. METHODS: Orbital tissues from 30 patients with TAO were compared with those of 20 patients with strabismus and four with non-thyroid orbital inflammation. TSHR was detected by immunohistochemistry and TRAB were measured by radioreceptor assay. RESULTS: No TSHR immunoreactivity was detected in the 24 control orbital tissues, whereas in all TAO biopsies elongated fibroblast-like cells, expressing TSHR, were present. These cells were located between the muscle cells, which were separated by oedema in the acute phase but fibrous tissue in the chronic phase of disease. Semi-thin sections showed numerous mast cells present in the chronic phase and in close contact with adipocytes. The number of TSHR immunostained cells was high in early disease, decreased with disease duration, and was positively correlated with TRAB levels at the onset of TAO. CONCLUSION: TSHR immunoreactivity was demonstrated specifically in TAO orbits which highlights the importance of TRAB early in the pathogenesis.Journal Articleinfo:eu-repo/semantics/publishe

Epithelial Rab guanine nucleotide exchange factor 1 (Rabgef1) deficiency increases susceptibility to DSS-induced intestinal inflammation in mice

Rab guanine nucleotide exchange factor (GEF)1 (Rabgef1) is a guanine nucleotide exchange factor for the endocytic GTPase Rab5, and also exhibits E3 ubiquitin ligase activity in vitro. In vivo functions of Rabgef1 remain largely unknown, but Rabgef1 is critical for health, as globally Rabgef1-deficient mice exhibit perinatal mortality and those surviving to adulthood spontaneously develop severe skin inflammation.This protein is highly expressed in murine intestinal epithelial cells (IECs). Objective: The aim of this study is to clarify the role of Rabgef1 in murine IECs Materials and methods: We performed conditional deletion of Rabgef1 using the cre-lox system to obtain mice lacking Rabgef1 specifically in IECs (Rabgef1IEC-KO). Results: Rabgef1IEC-KO mice did not develop spontaneous intestinal abnormalities but showed an increased susceptibility to inflammation in dextran sodium sulfate (DSS)-induced col itis model. Indeed, compared to littermate controls, mice lacking Rabgef1 in IECs exhibited shorter and highly inflamed colons and higher inflammatory scores in histopathological examination of colons, suggesting that Rabgef1 expression regulates IEC function and is critical in limiting DSS induced inflammation and damage. In addition, we also showed that mRNA expression of pro-inflammatory cytokines, such as Il1b and Tnfa, was upregulated in IECs isolated from Rabgef1IEC-KO mice compared to the ones isolated from littermate controls. Conclusion: Taken together, these results suggest that Rabgef1 acts as a regulator of intestinal homeostasis, and that dysregulated Rabgef1 expression could contribute to intestinal barrier dysfunction in inflammatory conditions of the gut
