ABSTRACT

PURPOSE: We assumed that in Palliative Care, even in common clinical situations, the choice of drugs differs substantially between physicians. Therefore, we assessed the practice of pharmaceutical treatment choices of physicians for cancer pain and opioid-induced nausea and vomiting (OINV) and the rationale for their choices. METHODS: An online survey was conducted with physicians covering the following domains: i) Cancer pain therapy: non-opioids in addition to opioids: choice of drug ii) prevention of OINV: choice of drug and mode of application. Current guidelines concerning cancer pain therapy and prevention of OINV were compared. RESULTS: Two-hundred-forty European physicians responded to our survey. i) Use of non-opioids in addition to opioids for the treatment of cancer pain: Only 1.3% (n = 3) of respondents never used an additional non-opioid. Others mostly used: dipyrone/metamizole (49.2%, n = 118), paracetamol/acetaminophen (34.2%, n = 82), ibuprofen / other NSAIDs (11.3%, n = 27), specific Cox2-inhibitors (2.1%, n = 5), Aspirin (0.4%, n = 1), no answer (2.9%, n = 7). ii) Antiemetics to prevent OINV: The drugs of choice were metoclopramide (58.3%, n = 140), haloperidol (26.3%, n = 63), 5-HT3 antagonists (9.6%, n = 23), antihistamines (1.3%, n = 3) and other (2.9%, n = 7); no answer (1.7%, n = 4). Most respondents prescribed the substances on-demand (59.6%, n = 143) while others (36.3%, n = 87) provided them as around the clock medication. Over both domains, most physicians answered that their choices were not based on solid evidence from randomized controlled trials (RCTs). Guidelines were inconsistent regarding if and what non-opioid to use for cancer pain and recommend anti-dopaminergic drugs for prevention or treatment of OINV. CONCLUSIONS: Physician's practice in palliative care for the treatment of cancer pain and OINV differed substantially. Respondents expressed the lack of high-quality evidence- based information from RCTs. We call for evidence from methodologically high-quality RCTs to be available to inform physicians about the benefits and harms of pharmacological treatments for common symptoms in palliative care.

ABSTRACT

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is responsible for 2.9 million deaths annually in Europe. Symptom burden and functional decline rise as patients reach advanced stages of the disease enhancing risk of vulnerability and dependency on informal caregivers (ICs).Evidence shows that hope is an important psycho-social-spiritual construct that humans use to cope with symptom burden and adversity. Hope is associated with increased quality of life (QoL) comfort and well-being for patients and ICs. A better understanding of the meaning and experience of hope over time as patients transition through chronic illness may help healthcare professionals to plan and deliver care more appropriately. METHODS AND ANALYSIS: This is a longitudinal multicentre mixed-methods study with a convergent design. Quantitative and qualitative data will be collected from dyads of advanced COPD patients and their ICs in two university hospitals at two points in time. The Herth Hope Index, WHO Quality of Life BREF, Functional Assessment of Chronic Illness Therapy-Spiritual Well-being and the French version of the Edmonton Symptom Assessment Scale will be used to collect data. Dyadic interviews will be conducted using a semi-structured interview guide with five questions about hope and their relationship with QoL.Statistical analysis of data will be carried out using R V.4.1.0. To test whether our theoretical model as a whole is supported by the data, structural equation modelling will be used. The comparison between T1 and T2 for level of hope, symptom burden, QoL and spiritual well-being, will be carried out using paired t-tests. The association between symptom burden, QoL, spiritual well-being and hope will be tested using Pearson correlation. ETHICS AND DISSEMINATION: This study protocol received ethical approval on 24 May 2022 from the Commission cantonale d'éthique de la recherche sur l'être humain-Canton of Vaud. The identification number is 2021-02477.

ABSTRACT

BACKGROUND: For the treatment of breathlessness in heart failure (HF), most textbooks advocate the use of opioids. Yet, meta-analyses are lacking. METHODS: A systematic review was performed for randomised controlled trials (RCTs) assessing effects of opioids on breathlessness (primary outcome) in patients with HF. Key secondary outcomes were quality of life (QoL), mortality and adverse effects. Cochrane Central Register of Controlled Trials, MEDLINE and Embase were searched in July 2021. Risk of bias (RoB) and certainty of evidence were assessed by the Cochrane RoB 2 Tool and Grading of Recommendations Assessment, Development and Evaluation criteria, respectively. The random-effects model was used as primary analysis in all meta-analyses. RESULTS: After removal of duplicates, 1180 records were screened. We identified eight RCTs with 271 randomised patients. Seven RCTs could be included in the meta-analysis for the primary endpoint breathlessness with a standardised mean difference of 0.03 (95% CI -0.21 to 0.28). No study found statistically significant differences between the intervention and placebo. Several key secondary outcomes favoured placebo: risk ratio of 3.13 (95% CI 0.70 to 14.07) for nausea, 4.29 (95% CI 1.15 to 16.01) for vomiting, 4.77 (95% CI 1.98 to 11.53) for constipation and 4.42 (95% CI 0.79 to 24.87) for study withdrawal. All meta-analyses revealed low heterogeneity (I2 in all these meta-analyses was <8%). CONCLUSION: Opioids for treating breathlessness in HF are questionable and may only be the very last option if other options have failed or in case of an emergency. PROSPERO REGISTRATION NUMBER: CRD42021252201.

ABSTRACT

Leukocytoclastic vasculitis is a cutaneous, small-vessel vasculitis. In 50% of cases the aetiology is idiopathic but it can be linked to drugs, infections, autoimmune disorders and various types of cancer. Levamisole is used as an adulterant in cocaine and heroin and has been associated with the development of leukocytoclastic vasculitis. We describe an atypical presentation of a patient with levamisole-induced leukocytoclastic vasculitis who presented with diffuse skin abscesses and a purpuric rash of the upper and lower limbs. LEARNING POINTS: In patients with intravenous drug consumption and a clinical presentation of leukocytoclastic vasculitis, it is important to consider levamisole as a possible contributing factor.Negative screening for MPO-ANCA and PR3-ANCA antibodies does not exclude levamisole-induced leukocytoclastic vasculitis.Diagnostic criteria for leukocytoclastic vasculitis induced by levamisole have not yet been established.

ABSTRACT

Background: Reverse transcription polymerase chain reaction (RT-PCR) is the current standard of reference in the diagnosis of SARS-CoV-2 infection. In outpatient clinical practice, nasopharyngeal swab RT-PCR testing is still the most common procedure. The purpose of this systematic review and meta-analysis was to evaluate the sensitivity of RT-PCR nasopharyngeal assays. Methods: We searched three databases, including PubMed/MEDLINE, EMBASE, and Cochrane Library, using a comprehensive strategy. Studies investigating the sensitivity of SARS-CoV-2 RT-PCR nasopharyngeal assays in adults were included. Two reviewers extracted data and assessed trial quality independently. Pooled sensitivity and its confidence interval were computed using the meta package in R. Results: Thirteen studies were found eligible for the inclusion in the systematic review. Out of these, 25 different sub-studies were identified and included in the meta-analysis, which reported the sensitivities of 25 different nasopharyngeal RT-PCR assays. Finally, the overall pooled sensitivity resulted 89% (95% CI, 85.4 to 91.8%). Conclusion: Our study suggests that RT-PCR assays on nasopharyngeal specimens have a substantial sensitivity for diagnosing SARS-CoV-2 infection.

ABSTRACT

BACKGROUND: Palliative care (PC) for patients with advanced cancer improves symptom management and quality of life and may promote home deaths. Limited data are available regarding PC in advanced head and neck cancer (HNC) patients. The aim of this study was to describe the type of care and modalities of integration of specialized PC in a population of relapsed and/or metastatic head and neck cancer patients, followed in a single institution over 4 years. METHODS: Between January 2016 and December 2019, data on patients with relapsed and/or metastatic head and neck cancer not suitable for curative treatment diagnosed at the Oncology Institute of Southern Switzerland were reviewed retrospectively. Site, type and lines of treatment, treatment response, referral to specialist palliative care (yes or no), type of symptoms, tracheostomy and/or feeding-tube presence, and site of death were documented. Comparisons were made between patients benefitting from PC integration vs standard care. RESULTS: Eighty-six patients with relapsed/metastatic HNC were identified, 63 (73.3%) of whom were referred to specialized PC. Patients were mainly men (66, 76.7%), with a median age of 69 years (range 44-95). The most common site of tumour was the oropharynx (31, 36%), followed by the larynx (21, 24.4%), oral cavity (19, 22.1%), hypopharynx (14, 16.3%), and unknown primary (1, 1.2%). Forty-four patients (51.2%) were treated with systemic treatment. The median time interval between the diagnosis and palliative care referral was 1.7 months. At the time of our analysis, 69 patients had died (58 in the PC group and 11 in the non-PC group). Fifteen patients (25.9%) in the PC group and 4 (36.4%) in the non-PC group had received aggressive treatment (chemotherapy, tracheostomy and/or feeding tube) in the last month of life, with no significant difference between groups (p = 0.44). There was no difference in the incidence of home death (19.1% PC group vs 9.1% non-PC group, p = 0.67) or presence of caregiver (69.8% PC group vs 78.2% non-PC group, p = 0.58) between groups, while palliative care was associated with more opioid use (90.5% vs 17.4%, p < 0.0001). Patients in the PC group had a shorter survival compared to the non-PC group (5.7 vs 19.9 months, p = 0.0063). CONCLUSIONS: This study shows that patients appear to be at risk of receiving inappropriate invasive treatments close to death and of dying in hospital settings. Further research is needed to investigate how early PC may affect decision-making around treatments and improve HNC patients' holistic wellbeing.

ABSTRACT

Inflammatory response following SARS-CoV-2 infection results in substantial increase of amounts of intravascular pro-coagulant extracellular vesicles (EVs) expressing tissue factor (CD142) on their surface. CD142-EV turned out to be useful as diagnostic biomarker in COVID-19 patients. Here we aimed at studying the prognostic capacity of CD142-EV in SARS-CoV-2 infection. Expression of CD142-EV was evaluated in 261 subjects admitted to hospital for pneumonia and with a positive molecular test for SARS-CoV-2. The study population consisted of a discovery cohort of selected patients (n = 60) and an independent validation cohort including unselected consecutive enrolled patients (n = 201). CD142-EV levels were correlated with post-hospitalization course of the disease and compared to the clinically available 4C Mortality Score as referral. CD142-EV showed a reliable performance to predict patient prognosis in the discovery cohort (AUC = 0.906) with an accuracy of 81.7%, that was confirmed in the validation cohort (AUC = 0.736). Kaplan-Meier curves highlighted a high discrimination power in unselected subjects with CD142-EV being able to stratify the majority of patients according to their prognosis. We obtained a comparable accuracy, being not inferior in terms of prediction of patients' prognosis and risk of mortality, with 4C Mortality Score. The expression of surface vesicular CD142 and its reliability as prognostic marker was technically validated using different immunocapture strategies and assays. The detection of CD142 on EV surface gains considerable interest as risk stratification tool to support clinical decision making in COVID-19.

ABSTRACT

BACKGROUND AND OBJECTIVE: Dexmedetomidine is a potent adrenergic alpha-2 receptor agonist. It was first approved for sedation for mechanically ventilated patients. Being a sedative medication that is not associated with respiratory depression and holding analgesic properties fosters the interest for this drug in the palliative care field. The primary objectives of this review were to identify the key indications for the real-world use of dexmedetomidine in palliative care and other disciplines. METHODS: A narrative review after extensive PubMed search was performed from 1950 to present on October 21st 2021. The language of the publications was restricted to English, German, French and Italian. KEY CONTENT AND FINDINGS: (I) Current dexmedetomidine use. There is a growing body of evidence that dexmedetomidine may reduce the incidence and severity of delirium, reduce opioid-consumption and postoperative nausea in intensive care settings. It is also used to facilitate withdrawal from different substances (alcohol, opioids, heroin). Concerning safety aspects of the drug, some studies reported an increased rate of serious cardiovascular events in patients with pre-existing heart conditions due to bradycardia and arterial hypo- and hypertension. Since the drug has a main hepatic metabolism, dose reduction is mandatory in patients with hepatic impairment. (II) Dexmedetomidine and palliative care. There have been sporadic case reports about the successful use of dexmedetomidine in palliative care. Indications for symptom control included sedation for hyperactive delirium, cancer pain, opioid-induced-hyperalgesia, dystonia, cough, vomiting, shivering and dyspnea. It is mainly applied via the intravenous (i.v.), subcutaneous, but also nasal and, buccal routes. Admixture ("syringe-driver") studies showed that dexmedetomidine is compatible with morphine, hydromorphone, hyoscine and haloperidol. In 2021, a first prospective cohort study became available. Here, the authors reported promising result for dexmedetomidine use in hyperactive terminal delirium for reducing delirium intensity and agitation. Especially the unique "conscious sedation" or "awake sedation" that allows patients to arouse easily under sedation and report comfort or distress was discussed by the authors. CONCLUSIONS: In this review, we present the main findings for dexmedetomidine from palliative care settings and other disciplines. The potential benefits and criticalities of the drug are discussed and practical recommendations for its use are provided.

ABSTRACT

All over the world, SARS-CoV-2 pneumonia is causing a significant short and medium-term morbidity and mortality, with reported persisting symptoms, radiological and lung alterations up to 6 months after symptoms onset. Nevertheless, the 1-year impact on affected patients is still poorly known. In this prospective observational study, 39 patients with SARS-CoV-2 pneumonia were recruited from a single COVID-19 hospital in Southern Switzerland. They underwent a 3-month and 1-year follow-ups. At 1 year, 38 patients underwent functional follow-up through lung function tests and six minutes walking test and submitted SF-12 and SGRQ questionnaires about health-related quality of life. At 1 year most of the patients showed a persistence of the radiological and functional abnormalities and a reduction of the health-related quality of life. Thirty patients (96.8%) still presented some residual abnormalities on CT scans (31 patients at 3 months), though with a general reduction of the lesional load in all lung lobes. Twenty patients (52.6%) had persisting lung function tests impairment, with an overall improvement of DLCO. As concerning the functional status, lowest SpO2 during 6MWT increased significantly. Finally, 19 patients (50%) reported a pathological St. George's Respiratory Questionnaire, and respectively 12 (31.6%) and 11 (28.9%) patients a pathological Short Form Survey-12 in physical and mental components. At 1-year follow-up SARS-CoV-2 pneumonia survivors still present a substantial impairment in radiological and functional findings and in health-related quality of life, despite showing a progressive recovery.

ABSTRACT

We present the unusual case of a 62-year-old male with profound asthenia and dyspnea for the last two months. Blood exams showed a severe hypercalcemia. Suspecting an underlying malignancy, we performed a 18F-FDG PET-CT, revealing widespread metabolic uptakes in muscles, consistent with an inflammatory process. The muscular biopsy showed a non-necrotising granuloma with multinucleated giant cells, pathognomonic for the diagnosis of acute isolated muscular sarcoidosis. A high-dose steroid therapy was started with clinical improvement and serum calcium normalization.

ABSTRACT

The provision of high-quality palliative care in nursing homes (NHs) requires specific knowledge and skills among health professionals. The aims of the study were to assess quality of care during the dying process and quality of end-of-life of NH residents in the French and Italian parts of Switzerland. 90 residents died during the study period (mean age 88.7 years). Mean of the "End-of-Life in Dementia Scales - Comfort Assessment while Dying" score was 35.7 (theoretical range 14-42). Mean of the "Quality of Dying in LongTerm Care" score was 38.3 (theoretical range 11-55). In conclusion, the quality of dying and quality of end-of-life care in NH studied can be improved improved, in particular on the anticipation level. Die Bereitstellung einer qualitativ hochwertigen Palliativversorgung in Pflegeheimen erfordert spezifische Fähigkeiten. Ziel der Studie war es, die Qualität der Sterbebegleitung von Bewohnern, die in der französisch- und italienischsprachigen Schweiz in Pflegeheimen sterben, zu bewerten. 90 Bewohner starben während der Studiendauer (Durchschnittsalter 88,7 Jahre). Der mittlere Wert der «End-of-Life in Dementia Scales - Comfort Assessment while Dying¼ lag bei 35,7 (theoretischer Bereich 14-42). Der Mittelwert der Skala «the Quality of Dying in LongTerm Care¼ lag bei 38,3 (theoretischer Bereich 11-55). Zusammenfassend lässt sich sagen, dass die Qualität der Versorgung am Lebensende in den untersuchten Pflegeheimen verbessert werden kann, insbesondere im Hinblick auf die Antizipation.

ABSTRACT

Patients with advanced COPD have a high symptom burden that is often multidimensional. Identification of patients who might benefit from palliative care through validated identification tools, multidimensional symptom management, and timely discussion of advance planning are elements of a palliative care approach for these patients and their families. Coordination among stakeholders providing care and support to these patients is central to ensuring high-quality care and meeting all of their needs.

ABSTRACT

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a life-limiting condition with palliative care needs. Despite increasing awareness about the role palliative care can play in care provision for patients with advanced COPD, integration in standard care remains underdeveloped. The unpredictability of the disease progression and misconceptions about palliative care being equivalent to end-of-life care often prevent a timely integrated approach in advanced COPD. AIM: To identify practices designed to increase integration of palliative care in the management of patients with advanced COPD in a respiratory service in Southern Switzerland. DESIGN: A participatory action research approach was chosen and key stakeholders were involved to develop new knowledge and practices, supported by a Theory of Change framework. Data from each cycle and retrospective analysis at the end of the whole research were analysed using thematic analysis. SETTING/PARTICIPANTS: Five action research cycles with seven healthcare professionals working in palliative or respiratory care settings were conducted. RESULTS: Three elements of integrated palliative care in advanced COPD were identified: multidimensional assessment, healthcare professionals' education and interdisciplinary team meetings, which are the pillars of a new integrated palliative care model for patients with advanced COPD. CONCLUSIONS: The new integrated palliative care model in advanced COPD includes essential elements with a focus on patients, healthcare professionals and care delivery. Further research on testing this model in clinical practice, service development, implementation processes and possible outcomes, including evaluation of the financial impact of integrated palliative care is necessary to foster this care approach across all possible settings.

ABSTRACT

We present the case of a 72-year-old woman who was diagnosed with Hashimoto's thyroiditis and who developed a low-grade fever, fatigue, and weight loss that prompted to perform a thyroid biopsy to rule out an underlying primary thyroid lymphoma. This case report offers the opportunity to review the association between Hashimoto's thyroiditis and primary thyroid lymphoma. Furthermore, it underlines the importance of considering the diagnosis of lymphoma when a thyroid mass is found in patients with an underlying Hashimoto's disease, as the timely management is essential for survival with this rare thyroid condition.

ABSTRACT

BACKGROUND: Coronavirus-2 (SARS-CoV-2) infection causes an acute respiratory syndrome accompanied by multi-organ damage that implicates a prothrombotic state leading to widespread microvascular clots. The causes of such coagulation abnormalities are unknown. The receptor tissue factor, also known as CD142, is often associated with cell-released extracellular vesicles (EV). In this study, we aimed to characterize surface antigens profile of circulating EV in COVID-19 patients and their potential implication as procoagulant agents. METHODS: We analyzed serum-derived EV from 67 participants who underwent nasopharyngeal swabs molecular test for suspected SARS-CoV-2 infection (34 positives and 33 negatives) and from 16 healthy controls (HC), as referral. A sub-analysis was performed on subjects who developed pneumonia (n = 28). Serum-derived EV were characterized for their surface antigen profile and tested for their procoagulant activity. A validation experiment was performed pre-treating EV with anti-CD142 antibody or with recombinant FVIIa. Serum TNF-α levels were measured by ELISA. FINDINGS: Profiling of EV antigens revealed a surface marker signature that defines circulating EV in COVID-19. A combination of seven surface molecules (CD49e, CD209, CD86, CD133/1, CD69, CD142, and CD20) clustered COVID (+) versus COVID (-) patients and HC. CD142 showed the highest discriminating performance at both multivariate models and ROC curve analysis. Noteworthy, we found that CD142 exposed onto surface of EV was biologically active. CD142 activity was higher in COVID (+) patients and correlated with TNF-α serum levels. INTERPRETATION: In SARS-CoV-2 infection the systemic inflammatory response results in cell-release of substantial amounts of procoagulant EV that may act as clotting initiation agents, contributing to disease severity.

ABSTRACT

BACKGROUND: All over the world, SARS-CoV-2 pneumonia is causing a significant short-term morbidity and mortality, but the medium-term impact on lung function and quality of life of affected patients are still unknown. METHODS: In this prospective observational study, 39 patients with SARS-CoV-2 pneumonia were recruited from a single COVID-19 hospital in Southern Switzerland. At three months patients underwent radiological and functional follow-up through CT scan, lung function tests, and 6 min walking test. Furthermore, quality of life was assessed through self-reported questionnaires. RESULTS: Among 39 patients with SARS-CoV-2 pneumonia, 32 (82% of all participants) presented abnormalities in CT scan and 25 (64.1%) had lung function tests impairment at three months. Moreover, 31 patients (79.5%) reported a perception of poor health due to respiratory symptoms and all 39 patients showed an overall decreased quality of life. CONCLUSIONS: Medium-term follow up at three months of patients diagnosed with SARS-CoV-2 pneumonia shows the persistence of abnormalities in CT scans, a significant functional impairment assessed by lung function tests and a decreased quality of life in affected patients. Further studies evaluating the long-term impact are warranted to guarantee an appropriate follow-up to patients recovering from SARS-CoV-2 pneumonia.

ABSTRACT

AIM: To identify and appraise evidence about ethical concerns regarding conducting medical research with end-of-life patients. DESIGN: A best-fit framework synthesis of the literature regarding ethical issues in research involving adult patients at the end of life was conducted. DATA SOURCES: Five databases were searched (Cumulative Index to Nursing and Allied Health Literature, Web of Science, Embase, MEDLINE, and PsychINFO) between January 2000-August 2019. REVIEW METHODS: Data were synthesized and categorized according to the moral positions described by Foster. RESULTS: In all, 18 papers that met the inclusion criteria were included in this review. These papers provided rich knowledge not only about various ethical objections to researching the end of life but also about the social, moral, and clinical requirements to perform rigorous studies on clinical interventions in this field. CONCLUSIONS: Research on people at end of life is not an unsolvable ethical dilemma between providing the best possible care and enhancing new therapies. It is important to find a balance between the moral duties of providing care and achieving research outcomes that are rigorous and meaningful for service users. IMPACT: Research ethics committees can be challenged by the evaluation of human research. This review provides up-to-date evidence on key challenges and ethical considerations about researching with end-of-life patients. SUMMARY STATEMENT: This study is a review of relevant evidence and key ethical challenges and issues around palliative and end-of-life research. Our findings provided important recommendations for clinicians, research, and ethics committee members when evaluating clinical research with people at their end of life.
