RESUMEN

For those of us who believe deeply in a collaborative relationship between patients and doctors, the chaos created by the COVID-19 pandemic has brought an uncomfortable question to the fore: Is participatory medicine still relevant during a pandemic? Drawing liberally upon the Jewish tradition of Talmudic reasoning, I would like to offer 3 considered replies: "Yes," "no," and "it depends." Sometimes, patients may have no choice but to cede control to medical professionals, even though patients are still the experts on their own lives. Other times, the shared control of participatory medicine is both an ethical and clinical imperative. However, as the worldwide toll exacted by COVID-19 has made us grimly aware, no one is really in control. That is why, in these uncertain times, the path forward requires maintaining mutual trust between health care providers and patients, whatever the circumstances. After all, it is our bodies and our selves at stake.

RESUMEN

The scope of health information and health care services available online is rapidly expanding. At the same time, COVID-19 is causing vulnerable elders to reconsider in-person provider visits. In that context, recently published research by Y. Mizrachi et al. examining obstacles to the use of online health services (OHS) among adults age 50 and up takes on new importance. An iconic Israeli song begins, "Will you hear my voice?" (Hebrew Songs. Zemer Nugeh (Hatishmah Koli), 2020). What makes Mizrachi et al.'s findings particularly intriguing, despite several caveats, is the manner in which they demonstrated a commitment to genuinely listen to individual voices. The researchers spoke "openly and bluntly" with interviewees as peers and were rewarded with "specific, well-defined and applicable answers with the potential to be used." The most striking findings came in candid answers that went beyond the factors intrinsic to the online offerings and addressed important factors in what regular Internet users often refer to as IRL ("in real life"), such as support from family. The necessity of avoiding preconceptions about the most effective manner to engage patients underscores the importance of patient and family advisory councils (PFACs). PFACs, increasingly being adopted by health care organizations globally, provide an ongoing ability to listen and respond to the "patient voice." Effectively addressing obstacles to older adults' use of the full range of online health resources will require the involvement not just of health plans and government, but also of voluntary organizations, providers, families and others integral to users' offline "real lives." Sustained, focused listening must be a central part of that effort.

RESUMEN

Attempting to enact Medicare for All in today's political climate is akin to a Starbucks barista saying he is torn between staying with his girlfriend and marrying Jennifer Lawrence: it is an unrealistic ideal. But if one also takes into account the genuine threat to the Affordable Care Act (ACA) from the Trump administration's decision to support a federal judge's controversial under-appeal ruling that the entire ACA is unconstitutional, the Medicare for All enthusiasm is even more alarming. It also ignores the unprecedented disruption to the lives of tens of millions of Americans such a massive change would create.

RESUMEN

Although there is a widespread belief that ACOs must be patient-centered to be successful, evidence to guide them in achieving that goal has been lacking. This case report examines four ACO innovators in patient-centered care that together represent urban, suburban and rural populations with a broad range of economic, racial, ethnic and geographic diversity. Seven patient-centeredness strategies emerged: transform primary care practices into patient-centered medical homes; move upstream to address social and economic issues; use both high-tech and high-touch to identify and engage high-risk patients; practice a whole-person orientation; optimize patient-reported measures; treat patients like valued customers; and incorporate patient voices into governance and operations. Exemplars prioritized direct care interventions perceived as central to financial and clinical success, and organizational maturity played a role. Activities that decreased the traditional system's authority, such as incorporating patient voices, were less popular. Local practice factors were important, and a mixture of mission and margin energized front-line staff in implementing patient-centered care as "the right thing to do." Unresolved questions remain that are related to the impact of individual and multiple interventions and how successful interventions can be disseminated widely. In order for patient-centeredness innovations to enable transformation, providers, payers and policymakers alike must consciously adopt strategies that nurture it.

RESUMEN

Venous thromboembolism (VTE) is common in patients with cancer and increases morbidity and mortality. VTE prevention and treatment are more complex in patients with cancer. The NCCN Guidelines for Cancer-Associated Venous Thromboembolic Disease outline strategies for treatment and prevention of VTE in adult patients diagnosed with cancer or in whom cancer is clinically suspected. These NCCN Guidelines Insights explain recent changes in anticoagulants recommended for the treatment of cancer-associated VTE.

RESUMEN

Over a third of adults go online to diagnose their health condition. Direct-to-consumer (DTC), interactive, diagnostic apps with information personalization capabilities beyond those of static search engines are rapidly proliferating. While these apps promise faster, more convenient and more accurate information to improve diagnosis, little is known about the state of the evidence on their performance or the methods used to evaluate them. We conducted a scoping review of the peer-reviewed and gray literature for the period January 1, 2014­June 30, 2017. We found that the largest category of evaluations involved symptom checkers that applied algorithms to user-answered questions, followed by sensor-driven apps that applied algorithms to smartphone photos, with a handful of evaluations examining crowdsourcing. The most common clinical areas evaluated were dermatology and general diagnostic and triage advice for a range of conditions. Evaluations were highly variable in methodology and conclusions, with about half describing app characteristics and half examining actual performance. Apps were found to vary widely in functionality, accuracy, safety and effectiveness, although the usefulness of this evidence was limited by a frequent failure to provide results by named individual app. Overall, the current evidence base on DTC, interactive diagnostic apps is sparse in scope, uneven in the information provided and inconclusive with respect to safety and effectiveness, with no studies of clinical risks and benefits involving real-world consumer use. Given that DTC diagnostic apps are rapidly evolving, rigorous and standardized evaluations are essential to inform decisions by clinicians, patients, policymakers and other stakeholders.

RESUMEN

BACKGROUND: Patients with relapsed or refractory lymphoma or chronic lymphocytic leukaemia have a poor prognosis. Therapies targeting more than one isoform of PI3K, as well as mTOR, might increase antitumour activity. We aimed to investigate the efficacy and safety of voxtalisib (also known as XL765 or SAR245409), a pan-PI3K/mTOR inhibitor, in patients with relapsed or refractory lymphoma, or chronic lymphocytic leukaemia/small lymphocytic lymphoma. METHODS: We did a non-randomised, open-label, phase 2 trial at 30 oncology clinics in the USA, Belgium, Germany, France, the Netherlands, and Australia. Patients aged 18 years or older with Eastern Cooperative Oncology Group (EGOG) performance status score of 2 or lower and relapsed or refractory mantle cell lymphoma, follicular lymphoma, diffuse large B-cell lymphoma, or chronic lymphocytic leukaemia/small lymphocytic lymphoma were enrolled and treated with voxtalisib 50 mg orally twice daily in 28-day continuous dosing cycles until progression or unacceptable toxicity. The primary endpoint was the proportion of patients in each disease-specific cohort who achieved an overall response, defined as a complete response or partial response. All patients who received more than 4 weeks of treatment and who completed a baseline and at least one post-baseline tumour assessment were analysed for efficacy and all patients were analysed for safety. This study is registered with ClinicalTrials.gov, number NCT01403636, and has been completed. FINDINGS: Between Oct 19, 2011, and July 24, 2013, 167 patients were enrolled (42 with mantle cell lymphoma, 47 with follicular lymphoma, 42 with diffuse large B-cell lymphoma, and 36 with chronic lymphocytic leukaemia/small lymphocytic lymphoma. The median number of previous anticancer regimens was three (IQR 2-4) for patients with lymphoma and four (2-5) for patients with chronic lymphocytic leukaemia/small lymphocytic lymphoma. Of 164 patients evaluable for efficacy, 30 (18·3%) achieved an overall response (partial, n=22; complete, n=8); 19 (41·3%) of 46 with follicular lymphoma, five (11·9%) of 42 with mantle cell lymphoma, two (4·9%) of 41 with diffuse large B-cell lymphoma, and four (11·4%) of 35 with chronic lymphocytic leukaemia/small lymphocytic lymphoma. The safety profile was consistent with that of previous studies of voxtalisib. The most frequently reported adverse events were diarrhoea (in 59 [35%] of 167 patients), fatigue (in 53 [32%]), nausea (in 45 [27%]), pyrexia (in 44 [26%,]), cough (in 40 [24%]), and decreased appetite (in 35 [21%]). The most frequently reported grade 3 or worse adverse events were anaemia (in 20 [12%] of 167 patients), pneumonia (in 14 [8%]), and thrombocytopenia (in 13 [8%]). Serious adverse events occurred in 97 (58·1%) of 167 patients. INTERPRETATION: Voxtalisib 50 mg given orally twice daily had an acceptable safety profile, with promising efficacy in patients with follicular lymphoma but limited efficacy in patients with mantle cell lymphoma, diffuse large B-cell lymphoma, or chronic lymphocytic leukaemia/small lymphocytic lymphoma. FUNDING: Sanofi.

RESUMEN

A prospective analysis of natural killer (NK) cell phenotype and function was performed on fresh peripheral blood samples from untreated patients with B-cell chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). Compared to healthy controls, CD56dim NK cells in CLL patients displayed reduced expression of the NKG2D activating receptor and increased CD27 expression, which indicates declines in mature cells. In addition, NK cells from CLL patients showed reduced degranulation responses toward transformed B cells alone or with rituximab and were more sensitive to activation-induced cell death. We further noted a striking reduction in the frequency and viability of NK cells expressing the inhibitory killer cell Ig-like receptors (KIR)2DL1 and/or KIR3DL1, which progressed over time in most patients. Comparisons between a CLL patient and healthy monozygotic twin were consistent with our results in the larger cohorts. Functional and biomarker alterations were less pronounced on NK cells from SLL patients, which have lower tumor burden in peripheral blood than CLL, but significant reduction in degranulation under ADCC conditions and lower frequency and viability of KIR-expressing NK cells were still evident in SLL. We conclude that mature KIR-expressing NK cells respond to the high circulating B cell tumor burden in CLL, but undergo activation-induced apoptosis. Consequently, CLL patients may benefit from therapies that augment NK cell survival and function.

RESUMEN

Although patient-centered care (PCC) was proclaimed a core health system aim in a 2001 Institute of Medicine report, it remains one of the most-used and least-understood terms in healthcare. We interviewed leaders at 15 Medicare accountable care organizations (ACOs) across the country that have been the most successful in putting patient-centeredness into actual practice to develop an operational definition. The ACOs we spoke with had a 3-pronged practical approach of: 1) patients as partners, 2) proactive customer-service orientation, and 3) care coordination with a whole-person approach. We believe this framework can serve as a guide as the healthcare system moves "from volume to value" and a true partnership becomes increasingly critical both to patients and the healthcare system as a whole.

RESUMEN

BACKGROUND: Tumor-infiltrating immune cells influence diffuse large B-cell lymphoma (DLBCL) outcomes. Relatively little, however, is known about the significance of peripheral blood immune cell numbers on DLBCL behavior. PATIENTS AND METHODS: In the present study, 43 patients with newly diagnosed DLBCL had pretreatment multiparameter peripheral blood flow cytometry performed to assess the immune cell numbers. These cell numbers were correlated with the outcomes of progression-free survival (PFS) and overall survival. RESULTS: After follow-up period of 0.8 to 152 months (median, 73), 25 patients (56%) were still alive. As continuous variables on univariate analysis, the predictors of PFS were patient age and absolute CD4 cell count (ACD4C), with the International Prognostic Index (IPI) marginally significant. Age was also a significant predictor of overall survival, and the IPI and ACD4C were marginally significant (P = .08). The 17 patients with a greater ACD4C (≥ 450/mm3) had better 5-year PFS than the 26 with a low ACD4C (88% vs. 50%; P = .02). Multivariable analysis, including age as a continuous variable, IPI group, and ACD4C of 450/mm3 showed that age and ACD4C were significant for PFS (P = .01 and P = .02, respectively). CONCLUSION: Our data, although from a small series, suggest that the blood ACD4C might be a predictor of PFS for patients with DLBCL, independent of age and the IPI.

RESUMEN

BACKGROUND: The impact of patient body habitus and sex on outcomes in diffuse large B-cell lymphoma (DLBCL) remains controversial. We investigated the impact of body mass index (BMI), body surface area (BSA), age, and sex on clinical outcomes in patients with DLBCL treated in the rituximab era. PATIENTS AND METHODS: Patients with de novo DLBCL (n=1,386) diagnosed between June 2000 and December 2010 treated with rituximab-containing chemotherapy were identified from the NCCN Oncology Outcomes Database for Non-Hodgkin's Lymphoma. Progression-free survival (PFS) and overall survival (OS) at 3 years were analyzed based on sex, age, and baseline BMI/BSA. RESULTS: High BMI was associated with a lower risk of disease progression or death than low or normal BMI, whereas male sex was associated with poor clinical outcomes, especially among elderly patients (age >60 years). Compared with elderly women, elderly men experienced worse PFS (3-year hazard ratio [HR], 1.5) and OS (3-year HR, 1.6), but these differences diminished with increases in BMI and BSA. In multivariable analysis, normal BMI compared with high BMI was independently associated with poor outcomes (3-year PFS HR, 1.5; OS HR, 1.6) after adjusting for sex. Notably, only 13% of elderly men had BMI less than 25 kg/m2 and only 26% had BSA less than 2 m2 CONCLUSIONS: Analysis of unselected patients with DLBCL treated with rituximab-containing chemotherapy confirmed an age-dependent disadvantage to male sex in treatment outcomes, but this effect is abrogated by higher levels of BMI and BSA in most North American men.

RESUMEN

PURPOSE: Cancer cells can exploit the programmed death-1 (PD-1) immune checkpoint pathway to avoid immune surveillance by modulating T-lymphocyte activity. In part, this may occur through overexpression of PD-1 and PD-1 pathway ligands (PD-L1 and PD-L2) in the tumor microenvironment. PD-1 blockade has produced significant antitumor activity in solid tumors, and similar evidence has emerged in hematologic malignancies. METHODS: In this phase I, open-label, dose-escalation, cohort-expansion study, patients with relapsed or refractory B-cell lymphoma, T-cell lymphoma, and multiple myeloma received the anti-PD-1 monoclonal antibody nivolumab at doses of 1 or 3 mg/kg every 2 weeks. This study aimed to evaluate the safety and efficacy of nivolumab and to assess PD-L1/PD-L2 locus integrity and protein expression. RESULTS: Eighty-one patients were treated (follicular lymphoma, n = 10; diffuse large B-cell lymphoma, n = 11; other B-cell lymphomas, n = 10; mycosis fungoides, n = 13; peripheral T-cell lymphoma, n = 5; other T-cell lymphomas, n = 5; multiple myeloma, n = 27). Patients had received a median of three (range, one to 12) prior systemic treatments. Drug-related adverse events occurred in 51 (63%) patients, and most were grade 1 or 2. Objective response rates were 40%, 36%, 15%, and 40% among patients with follicular lymphoma, diffuse large B-cell lymphoma, mycosis fungoides, and peripheral T-cell lymphoma, respectively. Median time of follow-up observation was 66.6 weeks (range, 1.6 to 132.0+ weeks). Durations of response in individual patients ranged from 6.0 to 81.6+ weeks. CONCLUSION: Nivolumab was well tolerated and exhibited antitumor activity in extensively pretreated patients with relapsed or refractory B- and T-cell lymphomas. Additional studies of nivolumab in these diseases are ongoing.

RESUMEN

The NCCN Guidelines for Cancer-Associated Venous Thromboembolic Disease outline strategies for treatment and prevention of venous thromboembolism (VTE) in adult patients with a diagnosis of cancer or for whom cancer is clinically suspected. VTE is a common complication in patients with cancer, which places them at greater risk for morbidity and mortality. Therefore, risk-appropriate prophylaxis is an essential component for the optimal care of inpatients and outpatients with cancer. Critical to meeting this goal is ensuring that patients get the most effective medication in the correct dose. Body weight has a significant impact on blood volume and drug clearance. Because obesity is a common health problem in industrialized societies, cancer care providers are increasingly likely to treat obese patients in their practice. Obesity is a risk factor common to VTE and many cancers, and may also impact the anticoagulant dose needed for safe and effective prophylaxis. These NCCN Guidelines Insights summarize the data supporting new dosing recommendations for VTE prophylaxis in obese patients with cancer.
