[Withdrawal of life sustaining treatment in the ICU - different doctors act differently]. / Hur livsuppehållande behandling avbryts på Iva ­ läkare gör olika.

Decisions to withdraw life sustaining treatment in the ICU are common, but there is little information about how treatment should be withdrawn. A pilot study showed that doctors withdraw life sustaining treatment in different ways even in identical cases. This variation can cause stress for ICU staff and relatives.  Our study investigated the decisions of doctors working in ICUs in Sweden regarding the withdrawal of life sustaining treatment for two fictitious patients. There was variation in if and how drug treatments should be withdrawn, as well as how ventilatory support should be withdrawn. Less experienced doctors tended to choose to prolong the dying process by weaning, even if it is unclear if that is preferable for the staff or for relatives.  Our study could be used in discussions in ICUs to try to understand how individual doctors make decisions about withdrawing life sustaining treatment.

[The oncologist, death and the pharmakon]. / L'oncologue, la mort et le pharmakon.

THE ONCOLOGIST, DEATH AND THE PHARMAKON. Stopping chemotherapy for patients treated in oncology is a difficult moment, feared by oncologists because it is often associated with abandonment or even failure in front of a resistant or aggressive disease. End-of-life chemotherapy is still common in oncology departments. However, it will be harmful if it causes side effects which alter the quality of life of patients or even hasten their death. But above all, this chemotherapy delays the implementation of appropriate palliative care support. Questioning the risk of hubris (excess) in some treatment, asking the relationship between the patient and his death, and prioritizing the quality of last moments is essential to best support patients on the path to the end o f life.

L'ONCOLOGUE, LA MORT ET LE PHARMAKON. L'arrêt des chimiothérapies des malades traités en oncologie est un moment difficile, redouté par les oncologues car souvent associé à un abandon, voire à un échec, face à une maladie résistante devenue trop agressive. La chimio thérapie de la fin de vie est encore fréquente dans les services d'oncologie. Elle est pourtant délétère si elle entraîne des effets indésirables qui altèrent la qualité de vie des malades, voire précipitent leur décès. Mais, surtout, cette chimiothérapie "de trop" retarde la mise en place d'un accompagnement adapté en soins palliatifs. Interroger le risque d'hubris de certains traitements, questionner le rapport à la mort du malade et privilégier la qualité du temps qui reste est pourtant essentiel pour accompagner au mieux les malades sur le chemin de la fin de vie.

Relapse following withdrawal of D-penicillamine from combination (D-penicillamine + zinc) therapy in hepatic Wilson disease.

OBJECTIVES: Long-term D-penicillamine (D-pen) therapy in Wilson disease (WD) has numerous adverse effects which advocates its withdrawal, but with an inherent risk of relapse. This prospective observational study was conducted with the objective of evaluating incidence of relapse following withdrawal of D-pen from combination (D-pen + zinc) therapy in maintenance phase of previously symptomatic hepatic WD. METHODS: Hepatic WD patients <18 years of age and on combination therapy for >2 years with 6 months of biochemical remission were included. Biochemical remission was defined as achievement of (i) aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤1.5 times upper limit of normal (ULN), (ii) serum albumin >3.5 g/dL, international normalized ratio (INR) <1.5 and (iii) 24-h urinary copper excretion (UCE) <500 mcg/day, nonceruloplasmin-bound-copper (NCC) <15 mcg/dL. After D-pen withdrawal, monthly liver function test (LFT) and INR and 3 monthly UCE and NCC were done till 1 year or relapse (elevation of AST/ALT/both >2 times ULN or total bilirubin >2 mg/dL), whichever occurred earlier. RESULTS: Forty-five patients enrolled with median combination therapy duration of 36 months. Sixty percent of them had their index presentation as decompensated cirrhosis. Fourteen patients (31.8%) relapsed (cumulative incidence: 4 at 3 months, 11 at 6 months, and 14 at 12 months after D-pen discontinuation). All relapsers had index presentation as decompensated cirrhosis. On Cox-regression, ALT at D-pen withdrawal was an independent predictor of relapse (hazard ratio [HR]: 1.077, 95% confidence interval [CI]: 1.014-1.145, p = 0.017) with area under the receiver operating characteristic (AUROC) of 0.860. ALT ≥40 U/L predicted risk of relapse with 85.7% sensitivity, 70.9% specificity. CONCLUSION: Incidence of relapse after withdrawal of D-pen from combination therapy is 31.8% in hepatic WD. ALT ≥40 U/L, at the time of D-pen stoppage, predicts future relapse.

Safe Stop IPI-NIVO trial: early discontinuation of nivolumab upon achieving a complete or partial response in patients with irresectable stage III or metastatic melanoma treated with first-line ipilimumab-nivolumab - study protocol.

BACKGROUND: Patients with irresectable stage III or metastatic melanoma presenting with poor prognostic factors are usually treated with a combination of immune checkpoint inhibitors (ICIs), consisting of ipilimumab and nivolumab. This combination therapy is associated with severe immune related adverse events (irAEs) in about 60% of patients. In current clinical practice, patients are usually treated with ICIs for up to two years or until disease progression or the occurrence of unacceptable AEs. The incidence of irAEs gradually increases with duration of treatment. While durable tumour responses have been observed after early discontinuation of treatment, no consensus has been reached on optimal treatment duration. The objective of the Safe Stop IPI-NIVO trial is to evaluate whether early discontinuation of ICIs is safe in patients with irresectable stage III or metastatic melanoma who are treated with combination therapy. METHODS: The Safe Stop IPI-NIVO trial is a nationwide, multicentre, prospective, single-arm, interventional study in the Netherlands. A total of 80 patients with irresectable stage III or metastatic melanoma who are treated with combination therapy of ipilimumab-nivolumab and have a complete or partial response (CR/PR) according to RECIST v1.1 will be included to early discontinue maintenance therapy with anti-PD-1. The primary endpoint is the rate of ongoing response at 12 months after start of ICI. Secondary endpoints include ongoing response at 24 months, disease control at different time points, melanoma specific and overall survival, the incidence of irAEs and health-related quality of life. DISCUSSION: From a medical, healthcare and economic perspective, overtreatment should be prevented and shorter treatment duration of ICIs is preferred. If early discontinuation of ICIs is safe for patients who are treated with the combination of ipilimumab-nivolumab, the treatment duration of nivolumab could be shortened in patients with a favourable tumour response. TRIAL REGISTRATION: ClinicalTrials.gov ID NCT05652673, registration date: 08-12-2022.

Discontinuation of imatinib in patients with oligometastatic gastrointestinal stromal tumour who are in complete radiological remission: a prospective multicentre phase II study.

INTRODUCTION: Metastatic gastrointestinal stromal tumour (GIST) is considered incurable, and life-long treatment with tyrosine kinase inhibitors is recommended. We investigated whether selected patients with metastatic GIST may remain in durable remission despite imatinib discontinuation. PATIENTS: In this 1-group, prospective, multicentre phase II trial selected patients with oligometastatic (≤3 metastases) GIST discontinued imatinib treatment. Eligible patients had been treated with imatinib >5 years without progression and had no radiologically detectable metastases after metastasectomy, radiofrequency ablation (RFA) or complete response to imatinib. The primary endpoint was progression-free survival (PFS) 3-years after stopping imatinib. Overall survival (OS) and quality of life (QoL) were secondary endpoints. RESULTS: The trial closed prematurely due to slow accrual. Between January 5, 2017, and June 5, 2019, 13 patients were enrolled, of whom 12 discontinued imatinib. The median follow-up time was 55 months (range, 36 to 69) after study entry. Five (42%) of the 12 eligible patients remained progression free, and seven (58%) progressed with a median time to progression 10 months. Median PFS was 23 months and the estimated 3-year PFS 41%. Six of the seven patients who progressed restarted imatinib, and all six responded. Three-year OS was 100%, and all patients were alive at the time of the study analysis. QoL measured 5 and 11 months after discontinuation of imatinib demonstrated improvement compared to the baseline. INTERPRETATION: A substantial proportion of selected patients with oligometastatic GIST treated with imatinib and metastasis surgery/RFA may remain disease-free for ≥3 years with improved QoL after stopping of imatinib.

Urban people's preferences for life-sustaining treatment or artificial nutrition and hydration in advance decisions.

BACKGROUND: The Patient Right to Autonomy Act (PRAA), implemented in Taiwan in 2019, enables the creation of advance decisions (AD) through advance care planning (ACP). This legal framework allows for the withholding and withdrawal of life-sustaining treatment (LST) or artificial nutrition and hydration (ANH) in situations like irreversible coma, vegetative state, severe dementia, or unbearable pain. This study aims to investigate preferences for LST or ANH across various clinical conditions, variations in participant preferences, and factors influencing these preferences among urban residents. METHODS: Employing a survey of legally structured AD documents and convenience sampling for data collection, individuals were enlisted from Taipei City Hospital, serving as the primary trial and demonstration facility for ACP in Taiwan since the commencement of the PRAA in its inaugural year. The study examined ADs and ACP consultation records, documenting gender, age, welfare entitlement, disease conditions, family caregiving experience, location of ACP consultation, participation of second-degree relatives, and the intention to participate in ACP. RESULTS: Data from 2337 participants were extracted from electronic records. There was high consistency in the willingness to refuse LST and ANH, with significant differences noted between terminal diseases and extremely severe dementia. Additionally, ANH was widely accepted as a time-limited treatment, and there was a prevalent trend of authorizing a health care agent (HCA) to make decisions on behalf of participants. Gender differences were observed, with females more inclined to decline LST and ANH, while males tended towards accepting full or time-limited treatment. Age also played a role, with younger participants more open to treatment and authorizing HCA, and older participants more prone to refusal. CONCLUSION: Diverse preferences in LST and ANH were shaped by the public's current understanding of different clinical states, gender, age, and cultural factors. Our study reveals nuanced end-of-life preferences, evolving ADs, and socio-demographic influences. Further research could explore evolving preferences over time and healthcare professionals' perspectives on LST and ANH decisions for neurological patients..

[Discontinuing disease-modifying therapies in multiple sclerosis]. / Traitements de la sclérose en plaques : quand les arrêter ?

Aging in multiple sclerosis (MS) leads to altered clinical manifestations, where the pathophysiology shifts towards compartmentalized inflammation that drives clinical progression independent of relapse activity. Consequently, the effectiveness of disease-modifying therapies (DMTs) diminishes in older patients, coinciding with an elevated risk of adverse events. This raises the question of whether MS therapies should be discontinued after a certain age, which is often proposed for patients over 55 years. Studies on treatment discontinuation have shown a slight increase in disease activity, yet without significant disability progression. This suggests that the decision to stop DMTs should be discussed with older patients, considering existing comorbidities. Following the cessation of therapy, meticulous monitoring is essential.

L'avancée en âge modifie la présentation clinique de la sclérose en plaques (SEP). La physiopathologie évolue progressivement au profit d'une inflammation restreinte au système nerveux central entraînant une progression clinique indépendante des poussées. Cette évolution est associée à une baisse d'efficacité des traitements de la SEP, alors qu'en parallèle le risque de complications augmente. Se pose donc la question d'un arrêt des thérapies de la SEP après un certain âge, souvent proposé à 55 ans. Bien que les premières études suggèrent une légère reprise d'activité à l'arrêt des traitements, celle-ci n'est pas associée à une progression du handicap. L'arrêt du traitement chez les patients les plus âgés devrait donc être envisagé en prenant en compte les comorbidités. Par la suite, une surveillance méticuleuse est indispensable.

How Seeking Transfer Often Fails to Help Define Medically Inappropriate Treatment.

On September 1, 2023, Texas made important revisions to it its decades-old statute granting legal safe harbor immunity to physicians who withhold or withdraw life-sustaining treatment over the objection of critically ill patients' surrogate decision-makers. However, lawmakers left untouched glaring flaws in a key safeguard for patients-the transfer option. The transfer option is ethically important because, when no hospital is willing to accept the patient in transfer, that fact is taken as strong evidence that the surrogates' treatment requests fall outside accepted medical practice. But there are serious shortcomings in how the transfer option is carried out in Texas and many other states, which undermines the ethical usefulness of the process. We identify these shortcomings and recommend revisions to state statutes and professional guidelines to overcome them.

The experiences among bereaved family members after a left ventricular assist device (LVAD) deactivation.

BACKGROUND: The use of left ventricular assist devices (LVADs) is increasing with an estimated 2500 devices implanted each year. When burdens of the LVAD outweigh benefits, most individuals with LVADs will undergo deactivation in the hospital setting. While the decision to deactivate an LVAD is considered an ethical practice, little is known about the experience and needs of bereaved family members. OBJECTIVE: To investigate the experiences of bereaved family members of patients who died following LVAD deactivation. METHODS: In this qualitative study, 11 family members of patients who underwent LVAD deactivation were interviewed. The semi-structured interviews were conducted until data saturation was reached and relevant themes emerged. RESULTS: This qualitative study was conducted to understand the experience of family members before, during and after the patient underwent LVAD deactivation, including their perceptions of engagement with the healthcare team. Analysis revealed six overarching themes from the experience, including 1) hope for survival, 2) communication, 3) spirituality and faith, 4) absence of physical suffering, 5) positive relationships with staff, 6) post-death care needs. CONCLUSION: Bereaved family members of patients undergoing LVAD deactivation have unique lived experiences and concerns. This study highlights the importance of effective communication not only near end-of-life but throughout the LVAD experience. While the positive relationships with staff and the absence of physical suffering were strengths identified by bereaved caregivers, there is an opportunity for improvement, particularly during the decision-making and post-death periods.

Analysis of antiretroviral therapy interruption in people living with HIV during the 2010-2021 Period. / [Artículo traducido] Análisis de la interrupción de la terapia antirretroviral en personas que viven con VIH/sida durante el periodo 2010­2021.

OBJECTIVE: In the context of the advancement of antiretroviral therapy and, as the characteristics of people living with HIV progress toward an aging population, understanding the causes of treatment interruption becomes crucial. The aim of the study was to determine the change in reasons for antiretroviral treatment discontinuation for 12 years. Secondarily, compare annual antiretroviral regimen discontinuation rate and factors associated. METHODS: We conducted an analysis using data from people living with HIV who were receiving antiretroviral therapy and discontinued it for any reason. The study included people with HIV infection who visited an outpatient hospital pharmacy clinic from January 2010 to December 2021. Two periods were differentiated for the analysis: 2010-2015 and 2016-2021. The reasons for antiretroviral treatment discontinuation followed classification described by Swiss cohort. In the context of this study, it is pertinent to note that the term 'interruption' will be consistently used in this article to refer to the act of switching or stopping antiretroviral treatment. To examine factors associated with antiretroviral therapy discontinuation, we utilized Kaplan-Meier methods and Cox proportional models. RESULTS: We included 789 people living with HIV, predominantly male (81,5%). The main reason for discontinuation was clinical decision (50.2%) followed by adverse effects (37.9%). Focusing on clinical decision, we observed a trend change that went from antiretroviral treatment simplification regimen (56.1%) in the first part of the period analyzed to the therapeutic optimization (53.6%) in the second half. Furthermore, factors that were statistically significantly associated with antiretroviral treatment discontinuation were people with HIV ≥50 years (HR 1.60; 95%CI 1.25-2.04), post-discontinuation single-tablet regimen (HR 1.49; 95%CI 1.06-2.11) and antiretroviral drug classes. CONCLUSIONS: Over the 12 years there has been a change in the main cause of antiretroviral treatment discontinuation, currently therapeutic optimization being the main reason. Integrase inhibitors-based regimens and singletablet regimen strategies were less likely to be discontinued than others antiretroviral drug classes, allowing for better clinical management due to the efficacy profile, especially in people living with HIV ≥50 years with comorbidities.

Deterioration of Performance Status during Palliative Radiotherapy Suggests a Significant Short Survival Duration: Indicating the Necessities for Considering Radiotherapy Discontinuation.

Discontinuation of palliative radiotherapy due to a patient's declining general condition poses a clinical dilemma for palliative care physicians. This study aimed to investigate the survival duration of patients whose performance status (PS) deteriorated during palliative radiotherapy and inform decisions regarding early treatment discontinuation. We retrospectively analyzed data from patients referred from our institute's palliative care department who underwent ≥10 fractions of palliative radiotherapy between March 2017 and December 2021. PS was assessed using the Eastern Cooperative Oncology Group (ECOG) scale. Survival duration was calculated from the final day of palliative radiotherapy to death using the Kaplan-Meier method. A total of 35 patients underwent palliative radiotherapy. Seven (20%) experienced deterioration in ECOG PS during treatment. Their median survival duration was significantly shorter at 22 days (95% confidence interval: 1-94 days) compared to 125 days (95% confidence interval: 82-150 days) for the 28 patients whose PS remained stable (p = 0.0007). Deterioration in ECOG PS during palliative radiotherapy signifies a markedly shorter survival duration. Careful assessment of a patient's condition throughout treatment is crucial, and early discontinuation should be considered if their general health worsens rather than strictly adhering to the initial schedule.

Quantitative Measurement of Serum HBcrAg Can Be Used to Assess the Feasibility of Safe Discontinuation of Antiviral Therapy for Chronic Hepatitis B.

Hepatitis B virus (HBV) infection is a serious global health problem, and chronic HBV infection significantly increases the risk of liver fibrosis, cirrhosis, and even hepatocellular carcinoma in patients. Current first-line therapeutics such as nucleos(t)ide analogues and interferons are unable to completely clear cccDNA, so the vast majority of patients need to take long-term or even lifelong medication. However, long-term virological and biochemical responses can be achieved in some patients after drug withdrawal. Successfully screening these patients with drug withdrawal advantages is difficult. Hepatitis-B-core-related antigen (HBcrAg) is a new HBV serological marker that which can reflect the level and transcription activity of cccDNA in hepatocytes. Therefore, HBcrAg has potential value in guiding patients in drug withdrawal. This review summarizes previous reports on HBcrAg and evaluates the application value of HBcrAg in safe drug discontinuation.

Clinicians' approach to predicting post-cardiac arrest outcomes for patients enrolled in a United States clinical trial.

PURPOSE: Perceived poor prognosis can lead to withdrawal of life-sustaining therapies (WLST) in patients who might otherwise recover. We characterized clinicians' approach to post-arrest prognostication in a multicenter clinical trial. METHODS: Semi-structured interviews were conducted with clinicians who treated a comatose post-cardiac arrest patient enrolled in the Influence of Cooling Duration on Efficacy in Cardiac Arrest Patients (ICECAP) trial (NCT04217551). Two authors independently analyzed each interview using inductive and deductive coding. The clinician reported how they arrived at a prognosis for the specific patient. We summarized the frequency with which clinicians reported using objective diagnostics to formulate their prognosis, and compared the reported approaches to established guidelines. Each respondent provided demographic information and described local neuroprognostication practices. RESULTS: We interviewed 30 clinicians at 19 US hospitals. Most claimed adherence to local hospital neuroprognostication protocols (n = 19). Prognostication led to WLST for perceived poor neurological prognosis in 15/30 patients, of whom most showed inconsistencies with guidelines or trial recommendations, respectively. In 10/15 WLST cases, clinicians reported relying on multimodal testing. A prevalent theme was the use of "clinical gestalt," defined as prognosticating based on a patient's overall appearance or a subjective impression in the absence of objective data. Many clinicians (21/30) reported using clinical gestalt for initial prognostication, with 9/21 expressing high confidence initially. CONCLUSION: Clinicians in our study state they follow neuroprognostication guidelines in general but often do not do so in actual practice. They reported clinical gestalt frequently informed early, highly confident prognostic judgments, and few objective tests changed initial impressions. Subjective prognostication may undermine well-designed trials.

Treatment discontinuation in older people with multiple sclerosis.

PURPOSE OF REVIEW: The aim of this review was to examine the evidence for disease-modifying therapies (DMTs) discontinuation in older people with multiple sclerosis (MS). We first summarized aging-associated biological changes that influence MS progression and DMT effectiveness, and then summarized recent evidence in evaluating clinical outcomes of discontinuing DMTs in older people with MS. RECENT FINDINGS: Recent findings provide mixed evidence regarding the outcomes of DMT discontinuation in older people with MS. Retrospective observational studies suggested older age and longer stable duration on DMT before DMT discontinuation were associated with lower risk of relapse in people with MS. However, one randomized clinical trial did not demonstrate the noninferiority of DMT discontinuation. SUMMARY: The available clinical evidence examining DMT discontinuation in older people with MS remains inconclusive. More robust evidence from clinical trials and real-world data will be necessary to guide clinical decisions regarding DMT discontinuation in older people with MS.

C-peptide index at 2 h post-meal is a useful predictor of endogenous insulin secretory capacity and withdrawal from insulin therapy in subjects with type 2 diabetes.

AIMS: To evaluate the correlation between C-peptide index (CPI) at 2 h post-meal and endogenous insulin secretory capacity and to develop clinical models to predict the possibility of withdrawal from insulin therapy in patients with type 2 diabetes. METHOD: This was a single-centre retrospective study of patients with type 2 diabetes admitted to our hospital. Patients were divided into a withdrawal group (n = 72) and a non-withdrawal group (n = 75) based on whether they were able to withdraw from insulin therapy at discharge, and the correlation between CPI at 2 h after meal and diabetes-related parameters was evaluated. In addition, we created two clinical models to predict the possibility of withdrawal from insulin therapy using machine learning. RESULTS: The glycated haemoglobin values of the study participants were 87.8 ± 22.6 mmol/mo. The CPI at 2 h post-meal was 1.93 ± 1.28 in the non-withdrawal group and 2.97 ± 2.07 in the withdrawal group (p < 0.001). CPI at 2 h post-meal was an independent predictor of withdrawal from insulin therapy. In addition, CPI at 2 h post-meal was a better predictor than fasting CPI. Six factors associated with insulin therapy withdrawal (age, duration of diabetes, creatinine, alanine aminotransferase, insulin therapy until hospitalization, and CPI at 2 h post-meal) were used to generate two clinical models by machine learning. The accuracy of the generated clinical models ranged from 78.3% to 82.6%. CONCLUSION: The CPI at 2 h post-meal is a clinically useful measure of endogenous insulin secretory capacity under non-fasting conditions.

Preoperative GLP-1 Receptor Agonist Use and Risk of Postoperative Respiratory Complications.

This cohort study evaluates the risk of postoperative respiratory complications among patients with diabetes undergoing surgery who had vs those who had not a prescription fill for glucagon-like peptide 1 receptor agonists.
