Cytogenetic studies at diagnosis in polycythemia vera: clinical and JAK2V617F allele burden correlates.

The prognostic significance of cytogenetic findings at diagnosis in polycythemia vera (PV) was investigated in a retrospective series of 137 patients. Cytogenetics were normal in 117 patients (85%) and displayed a −Y abnormality in five patients (7% of male patients), and other chromosomal abnormalities in 15 patients (11%). The most frequent cytogenetic anomalies were trisomy 8 (n = 4), trisomy 9 (n = 2), deletion 20q (n = 2) and chromosomal 1 abnormalities (n = 2). Parameters that were significantly associated with abnormal cytogenetics included age ≥60 yr (P = 0.02), but not JAK2V617F allele burden, thrombosis, hemorrhage, leukemic/fibrotic transformation, or survival. We conclude that cytogenetic anomalies occur infrequently at PV diagnosis and do not confer an adverse outcome.

A survey of clinician attitudes and self-reported practices regarding end-of-life care in heart failure

Background: As heart failure often follows an unpredictable clinical trajectory, there has been an impetus to promote iterative patient-provider discussions regarding prognosis and preferences for end-of-life care. Aim: To examine clinicians’ practices, expectations, and personal level of confidence in discussing goals of care and providing end-of-life care to their patients with heart failure. Design: Multi-site clinician survey. Setting and Participants: Physicians, nurse practitioners, and physician assistants at Mayo Clinic (Rochester, Minnesota, USA) and its surrounding health system were asked to participate in an electronic survey in October 2013. Tertiary Care Cardiology, Community Cardiology, and Primary Care clinicians were surveyed. Results: A total of 95 clinicians participated (52.5% response rate). Only 12% of clinicians reported having annual end-of-life discussions as advocated by the American Heart Association. In total, 52% of clinicians hesitated to discuss end-of-life care citing provider discomfort (11%), perception of patient (21%) or family (12%) unreadiness, fear of destroying hope (9%), or lack of time (8%). Tertiary and Community Cardiology clinicians (66%) attributed responsibility for end-of-life discussions to the heart failure cardiologist, while 66% of Primary Care clinicians felt it was their responsibility. Overall, 30% of clinicians reported a low or very low level of confidence in one or more of the following: initiating prognosis or end-of-life discussions, enrolling patients in hospice, or providing end-of-life care. Most clinicians expressed interest in further skills acquisition. Conclusion: Clinicians vary in their views and approaches to end-of-life discussions and care. Some lack confidence and most are interested in further skills acquisition.

Respective clustering of unfavorable and favorable cytogenetic clones in myelofibrosis with myeloid metaplasia with homozygosity for JAK2V617F and response to erythropoietin therapy

Patients who have myelofibrosis with myeloid metaplasia (MMM) display recurrent, albeit nonspecific cytogenetic abnormalities that are diverse prognostically. For the current study, the authors explored the relation between specific cytogenetic clones and JAK2V617F mutational status in patients with MMM and the effects on treatment response to erythropoietin (Epo).

Top 10 Things Palliative Care Clinicians Wished Everyone Knew About Palliative Care

With a focus on improving quality of life for patients, palliative care is a rapidly growing medical subspecialty focusing on the care of patients with serious illness. Basic symptom management, discussions of prognostic understanding, and eliciting treatment goals are essential pieces in the practice of nearly all physicians. Nonetheless, many complex patients with a serious, life-threatening illness benefit from consultation with palliative care specialists, who are trained and experienced in complex symptom management and challenging communication interactions, including medical decision making and aligning goals of care. This article discusses the changing role of modern palliative care, addresses common misconceptions, and presents an argument for early integration of palliative care in the treatment of patients dealing with serious illness.

How to discuss goals of care with patients

Effective communication with patients and their caregivers continues to form the basis of a constructive clinician-patient relationship and is critical to provide patient-centered care. Engaging patients in meaningful, empathic communication not only fulfills an ethical imperative for our work as clinicians but also leads to increased patient satisfaction with their own care and improved clinical outcomes. While these same imperatives and benefits exist for discussing goals of care and end-of-life, communicating with patients about these topics can be particularly daunting. While clinicians receive extensive training on how to identify and treat illness, communication techniques, especially those centering around emotion-laden topics such as end-of-life care, receive short shrift medical education. Fortunately, communication techniques can be taught and learned through deliberate practice, and in this article, we seek to discuss a framework, drawn from published literature and our own experience, for approaching goals-of-care discussions in patients with cardiovascular disease.

Dying with a Left Ventricular Assist Device as Destination Therapy

Background—Despite the ability of left ventricular assist device as destination therapy (DT-LVAD) to prolong survival for many patients with advanced heart failure, little is known about the eventual end-of-life care that patients with DT-LVAD receive. Methods and Results—All patients undergoing DT-LVAD at the Mayo Clinic in Rochester, Minnesota, from January 1, 2007, to September 30, 2014, who subsequently died before July 1, 2015, were included. Information about end-of-life care was obtained from documentation in the electronic medical record. Of 89 patients who died with a DT-LVAD, the median (25th–75th percentile) time from left ventricular assist device implantation to death was 14 (4–31) months. The most common causes of death were multiorgan failure (26%), hemorrhagic stroke (24%), and progressive heart failure (21%). Nearly half (46%) of the patients saw palliative care within 1 month before death; however, only 13 (15%) patients enrolled in hospice a median 11 (range 1–315) days before death. Most patients (78%) died in the hospital, of which 88% died in the intensive care unit. In total, 49 patients had their left ventricular assist device deactivated before death, with all but 3 undergoing deactivation in the hospital. Most patients died within an hour of left ventricular assist device deactivation and all within 26 hours. Conclusions—In contrast to the general heart failure population, most patients with DT-LVAD die in the hospital and few use hospice. Further work is needed to understand these differences and to determine whether patients with DT-LVAD are receiving optimal end-of-life care.

Integrating palliative care in the intensive care unit.

The admission of cancer patients into intensive care units (ICUs) is on the rise. These patients are at high risk for physical and psychosocial suffering. Patients and their families often face difficult end-of-life decisions that highlight the importance of effective and empathetic communication. Palliative care teams are uniquely equipped to help care for cancer patients who are admitted to ICUs. When utilized in the ICU, palliative care has the potential to improve a patients symptoms, enhance the communication between care teams and families, and improve family-centered decision making. Within the context of this article, we will discuss how palliative care can be integrated into the care of ICU patients and how to enhance family-centered communication; we will also highlight the care of ICU patients at the end of life.

Pruritus in polycythemia vera is associated with a lower risk of arterial thrombosis

Among 418 patients with polycythemia vera seen at our institution and in whom pruritus history was recorded, the presence of pruritus at diagnosis was documented in 131 (31%) and its absence in 287 (69%). Pruritus was less frequently reported by smokers (12% vs. 24%; P = 0.004) and diabetics (5% vs. 11%; P = 0.04). The presence of pruritus was associated with a lower rate of arterial thrombosis, both at diagnosis (8% vs. 17%; P = 0.01) and during follow‐up (16% vs. 30%; P = 0.003). Multivariable analysis revealed that these associations were independent of other risk factors for thrombosis. High JAK2V617F allele burden clustered with pruritus (P = 0.002) but did not affect thrombosis rates. Am. J. Hematol., 2008.

Discordance of Patient-Reported and Clinician-Ordered Resuscitation Status in Patients Hospitalized With Acute Decompensated Heart Failure

CONTEXT Accurate documentation of preferences for cardiopulmonary resuscitation at hospital admission is critical to ensure that patients receive resuscitation or not in accordance with their wishes. OBJECTIVES We sought to identify and characterize inconsistencies in patient-reported and clinician-ordered resuscitation status in patients hospitalized with acute decompensated heart failure (ADHF). METHODS Southeastern Minnesota residents hospitalized with ADHF were prospectively enrolled into a study that included the administration of face-to-face questionnaires from January 2014 to February 2016. Patient-reported resuscitation status was assessed at enrollment using a validated question. Clinician-ordered resuscitation preferences at hospital admission were abstracted from the electronic medical record. RESULTS Of the 400 patients administered the questionnaire; 213 (53.3%) stated their resuscitation preference as Full Code, 166 (41.5%) do-not-resuscitate (DNR), and 21 (5.3%) were unsure. In comparison, clinician-ordered resuscitation status was Full Code in 263 (65.8%) patients, DNR in 133 (33.3%), and not documented in four (1.0%). Patient-reported and clinician-ordered resuscitation status was discordant in 20% of patients, of whom 5.6% elected Full Code by questionnaire and had a DNR clinician order, and 14.4% elected DNR by questionnaire but had a Full Code clinician order. Differences in age, comorbidities, health literacy, marital status, completion of advance directives, hospital length of stay, and discharge destination in patients with discordant vs. concordant resuscitation preferences were observed. CONCLUSIONS Patient-reported and clinician-ordered resuscitation preferences were discordant in 20% of patients hospitalized with ADHF. The underlying etiology of these inconsistencies may reflect factors such as patient indecisiveness or patient-clinician miscommunication and requires further exploration.
