RESUMEN

BACKGROUND: Interest and use of blended diets (BD) for young people who are tube fed has significantly increased in the last decade, driven primarily by the desires of motivated caregivers. This review identified, appraised and synthesised the available evidence on the benefits and complications of BD versus commercial feeds. METHODS: A systematic review following PRISMA guidance and registered with PROSPERO was conducted across PubMed, Embase, CINAHL, Scopus and Cochrane up to August 2022. INCLUSION CRITERIA: English language studies including (1) children, (2) original research (interventional and observational) and (3) examination of BD outcomes. Exclusion criteria were (1) unoriginal research or case reports, (2) focus on feeding management, preparations or attitudes and (3) comparing commercial blends only. Data were synthesised using an established narrative synthesis approach using the Mixed Methods Appraisal Tool. RESULTS: Eight hundred and six database results were identified and 61 were sought for retrieval. A full-text article review revealed seven eligible studies, involving 267 participants (age range 9 months to 26 years). Studies reported differences in gastrointestinal symptoms (n = 222), medication use (n = 119), growth (n = 189) and complications or adverse events (n = 91). The results indicate positive outcomes, particularly in gastrointestinal symptom control, with few reports of mild adverse events in the included studies. CONCLUSIONS: There is a paucity of data in this area and much heterogeneity in the included studies, but the available literature points towards positive outcomes. This is an important and highly relevant topic, and more primary research, ideally using standardised reporting, is required to answer the key questions.

RESUMEN

OBJECTIVE: Antitumour necrosis factor (anti-TNF) drugs impair protective immunity following pneumococcal, influenza and viral hepatitis vaccination and increase the risk of serious respiratory infections. We sought to determine whether infliximab-treated patients with IBD have attenuated serological responses to SARS-CoV-2 infections. DESIGN: Antibody responses in participants treated with infliximab were compared with a reference cohort treated with vedolizumab, a gut-selective anti-integrin α4ß7 monoclonal antibody that is not associated with impaired vaccine responses or increased susceptibility to systemic infections. 6935 patients were recruited from 92 UK hospitals between 22 September and 23 December 2020. RESULTS: Rates of symptomatic and proven SARS-CoV-2 infection were similar between groups. Seroprevalence was lower in infliximab-treated than vedolizumab-treated patients (3.4% (161/4685) vs 6.0% (134/2250), p<0.0001). Multivariable logistic regression analyses confirmed that infliximab (vs vedolizumab; OR 0.66 (95% CI 0.51 to 0.87), p=0.0027) and immunomodulator use (OR 0.70 (95% CI 0.53 to 0.92), p=0.012) were independently associated with lower seropositivity. In patients with confirmed SARS-CoV-2 infection, seroconversion was observed in fewer infliximab-treated than vedolizumab-treated patients (48% (39/81) vs 83% (30/36), p=0.00044) and the magnitude of anti-SARS-CoV-2 reactivity was lower (median 0.8 cut-off index (0.2-5.6) vs 37.0 (15.2-76.1), p<0.0001). CONCLUSIONS: Infliximab is associated with attenuated serological responses to SARS-CoV-2 that were further blunted by immunomodulators used as concomitant therapy. Impaired serological responses to SARS-CoV-2 infection might have important implications for global public health policy and individual anti-TNF-treated patients. Serological testing and virus surveillance should be considered to detect suboptimal vaccine responses, persistent infection and viral evolution to inform public health policy. TRIAL REGISTRATION NUMBER: ISRCTN45176516.

RESUMEN

Hypoxia-inducible factor prolyl hydroxylase domain 2 (PHD2) is an important oxygen sensor in animals. By using the CO-releasing molecule-2 (CORM-2) as an in situ CO donor, we demonstrate that CO is an inhibitor of PHD2. This report provides further evidence about the emerging role of CO in oxygen sensing and homeostasis.

RESUMEN

OBJECTIVES: The objective of the study was to explore how health evidence is submitted to national policymakers in the United Kingdom outside of the health sector. STUDY DESIGN: The study design used is document review. METHODS: The parliament.uk website was searched for House of Commons Select Committee inquiries relevant to health but not undertaken by the Health and Social Care Committee between 2015 and 2019. The written and oral evidence used in these inquiries were searched for submissions by health sources. RESULTS: Twenty-two inquiries were found, covering a range of determinants of health. A median of 10 pieces of written evidence (interquartile range [IQR] 5-16) and 16% of the oral evidence (IQR 6-32%) was provided by health sources, per inquiry. Health researchers contributed written evidence to 19 and oral evidence to 13 inquires. National public health organisations contributed written evidence to 11 and oral evidence to nine inquiries. CONCLUSIONS: A significant number of inquiries relating to the determinants of health were not carried out by the Health and Social Care Committee. Health sources variably contributed evidence to these inquiries. There is an opportunity to submit more evidence to national policymakers to advocate for healthy policies across sectors.

RESUMEN

Carbon nanodots (CNDs) are an emerging class of nanomaterials and have generated much interest in the field of biomedicine by way of unique properties, such as superior biocompatibility, stability, excellent photoluminescence, simple green synthesis, and easy surface modification. CNDs have been featured in a host of applications, including bioimaging, biosensing, and therapy. In this review, we summarize the latest research progress of CNDs and discuss key advances in our comprehension of CNDs and their potential as biomedical tools. We highlighted the recent developments in the understanding of the functional tailoring of CNDs by modifying dopants and surface molecules, which have yielded a deeper understanding of their antioxidant behavior and mechanisms of action. The increasing amount of in vitro research regarding CNDs has also spawned interest in in vivo practices. Chief among them, we discuss the emergence of research analyzing CNDs as useful therapeutic agents in various disease states. Each subject is debated with reflection on future studies that may further our grasp of CNDs.

RESUMEN

OBJECTIVE: Management of acute severe UC (ASUC) during the novel COVID-19 pandemic presents significant dilemmas. We aimed to provide COVID-19-specific guidance using current British Society of Gastroenterology (BSG) guidelines as a reference point. DESIGN: We convened a RAND appropriateness panel comprising 14 gastroenterologists and an IBD nurse consultant supplemented by surgical and COVID-19 experts. Panellists rated the appropriateness of interventions for ASUC in the context of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Median scores and disagreement index (DI) were calculated. Results were discussed at a moderated meeting prior to a second survey. RESULTS: Panellists recommended that patients with ASUC should be isolated throughout their hospital stay and should have a SARS-CoV-2 swab performed on admission. Patients with a positive swab should be discussed with COVID-19 specialists. As per BSG guidance, intravenous hydrocortisone was considered appropriate as initial management; only in patients with COVID-19 pneumonia was its use deemed uncertain. In patients requiring rescue therapy, infliximab with continuing steroids was recommended. Delaying colectomy because of COVID-19 was deemed inappropriate. Steroid tapering as per BSG guidance was deemed appropriate for all patients apart from those with COVID-19 pneumonia in whom a 4-6 week taper was preferred. Post-ASUC maintenance therapy was dependent on SARS-CoV-2 status but, in general, biologics were more likely to be deemed appropriate than azathioprine or tofacitinib. Panellists deemed prophylactic anticoagulation postdischarge to be appropriate in patients with a positive SARS-CoV-2 swab. CONCLUSION: We have suggested COVID-19-specific adaptations to the BSG ASUC guideline using a RAND panel.

RESUMEN

The COVID-19 pandemic is putting unprecedented pressures on healthcare systems globally. Early insights have been made possible by rapid sharing of data from China and Italy. In the UK, we have rapidly mobilised inflammatory bowel disease (IBD) centres in order that preparations can be made to protect our patients and the clinical services they rely on. This is a novel coronavirus; much is unknown as to how it will affect people with IBD. We also lack information about the impact of different immunosuppressive medications. To address this uncertainty, the British Society of Gastroenterology (BSG) COVID-19 IBD Working Group has used the best available data and expert opinion to generate a risk grid that groups patients into highest, moderate and lowest risk categories. This grid allows patients to be instructed to follow the UK government's advice for shielding, stringent and standard advice regarding social distancing, respectively. Further considerations are given to service provision, medical and surgical therapy, endoscopy, imaging and clinical trials.

RESUMEN

BACKGROUND: NEPA, a combination antiemetic of a neurokinin-1 (NK1 ) receptor antagonist (RA) (netupitant [oral]/fosnetupitant [intravenous; IV]) and 5-HT3 RA, palonosetron] offers 5-day CINV prevention with a single dose. Fosnetupitant solution contains no allergenic excipients, surfactant, emulsifier, or solubility enhancer. A phase III study of patients receiving cisplatin found no infusion-site or anaphylactic reactions related to IV NEPA. However, hypersensitivity reactions and anaphylaxis have been reported with other IV NK1 RAs, particularly fosaprepitant in patients receiving anthracycline-cyclophosphamide (AC)-based chemotherapy. This study evaluated the safety and efficacy of IV NEPA in the AC setting. MATERIALS AND METHODS: This phase IIIb, multinational, randomized, double-blind study enrolled females with breast cancer naive to highly or moderately emetogenic chemotherapy. Patients were randomized to receive a single 30-minute infusion of IV NEPA or single oral NEPA capsule on day 1 prior to AC, in repeated (up to 4) cycles. Oral dexamethasone was given to all patients on day 1 only. RESULTS: A total of 402 patients were included. The adverse event (AE) profiles were similar for IV and oral NEPA and consistent with those expected. Most AEs were mild or moderate with a similarly low incidence of treatment-related AEs in both groups. There were no treatment-related injection-site AEs and no reports of hypersensitivity or anaphylaxis. The efficacy of IV and oral NEPA were similar, with high complete response (no emesis/no rescue) rates observed in cycle 1 (overall [0-120 hours] 73.0% IV NEPA, 77.3% oral NEPA) and maintained over subsequent cycles. CONCLUSION: IV NEPA was highly effective and safe with no associated hypersensitivity and injection-site reactions in patients receiving AC. IMPLICATIONS FOR PRACTICE: As a combination of a neurokinin-1 (NK1 ) receptor antagonist (RA) and 5-HT3 RA, NEPA offers 5-day chemotherapy-induced nausea and vomiting prevention with a single dose and an opportunity to improve adherence to antiemetic guidelines. In this randomized multinational phase IIIb study, intravenous (IV) NEPA (fosnetupitant/palonosetron) was safe and highly effective in patients receiving multiple cycles of anthracycline-cyclophosphamide (AC)-based chemotherapy. Unlike other IV NK1 RAs, the IV NEPA combination solution does not require any surfactant, emulsifier, or solubility enhancer and contains no allergenic excipients. Hypersensitivity reactions and anaphylaxis have been reported with other IV NK1 RAs, most commonly with fosaprepitant in the AC setting. Importantly, there were no injection-site or hypersensitivity reactions associated with IV NEPA.

RESUMEN

The combination of more than one bioactive moiety in a multitargeted anticancer agent may result in synergistic activity of its components. Using this concept, bioorganometallic compounds were designed to feature a metal center, a 2-pyridinecarbothioamide (PCA), and a hydroxamic acid, which is found in the anticancer drug vorinostat (SAHA). The organometallics showed inhibitory activity in the nanomolar range against histone deacetylases (HDACs) as the key target for SAHA. In particular, the Rh complex was a potent inhibitor of HDAC6 over HDAC1 and HDAC8. Whereas this complex was highly cytotoxic in human cancer cells, it showed low toxicity in hemolysis studies and zebrafish, demonstrating the role of the metal center. For this complex a slightly reduced expression of vascular endothelial growth factor receptor 2 (VEGFR2) was established, which was upregulated by SAHA. This finding indicates that the new organometallics display different modes of action than their bioactive components.

RESUMEN

Chemical tools that recognise post-translational modifications have promising applications in biochemistry and in therapy. We report a simple carboxycalixarene that selectively binds molecules containing di/trimethylammonium moieties in isolation, in cell lysates and when incorporated in histone peptides. Our findings reveal the potential of using carboxycalixarene-based receptors to study epigenetic regulation.

RESUMEN

Septic discitis is a rare but important cause of spinal pain caused by intervertebral disc infection. This retrospective observational case series analysis will examine the clinical features and management of septic discitis in 23 patients and compare with a similar 2001 study. We will also review the evidence behind management recommendations to identify areas for future research. The incidence of septic discitis was 2 per 100,000 per year. Patients presented with spinal pain (96 %), fever (70 %) and raised inflammatory markers. All patients had blood cultures and 52 % had targeted microbiological analysis. Staphylococcus aureus was the most common causative organism (39 %). Treatment was most often with intravenous flucloxacillin or ceftriaxone. CT-guided sampling for culture before commencing antibiotics increased organism detection from 33 to 67 %, and organism identification reduced the antibiotic course from an average of 142 days to 77 days. An increased number of significant co-morbid conditions were associated with worse outcomes. Results broadly resembled the 2001 study. Key differences were increased use and yield of magnetic resonance imaging and computerised tomography (CT) scanning and more frequent use of intravenous antibiotics. Comparisons between the studies suggest that improvements in the consistency of management have been slow. We suggest this due to the large spectrum of disease and the lack of guidelines in the UK. It is widely recommended to perform blood cultures and CT-guided biopsies before starting antibiotics, but it is unclear how long to withhold antibiotics if cultures remain negative. Six weeks of intravenous followed by 6 weeks of oral therapy is often suggested as treatment, whereas some recommend using inflammatory markers to guide antibiotic duration. Larger studies addressing these specific questions are required to provide more definitive guidance for these clinical decisions.

RESUMEN

Mast cell (MC) activation syndrome (MCAS) is a recently recognized, likely prevalent collection of heterogeneous illnesses of inappropriate MC activation with little to no MC neoplasia likely driven by heterogeneous patterns of constitutively activating mutations in MC regulatory elements including various tyrosine kinases (TKs, dominantly KIT). MCAS typically presents as chronic multisystem polymorbidity of generally inflammatory ± allergic theme. As with indolent systemic mastocytosis (SM), treatment of MCAS focuses more against MC mediators than MC neoplasia, but some cases prove refractory even to the TK inhibitor (TKI) imatinib reported useful both in uncommon SM cases not bearing SM's usual imatinib-resistant KIT-D816V mutation and in some cases of MCAS (which rarely bears KIT-D816V). Most allergy is principally a MC activation phenomenon and sunitinib is a multitargeted TKI shown helpful in controlling a murine model of oral allergy syndrome. We present the first report of use of sunitinib in life-threatening MCAS refractory to multiple agents including imatinib achieving immediate, complete, sustained, non-toxic remission suggesting a new option for treatment of aggressive MC disease.

RESUMEN

BACKGROUND: We have previously reported that higher patient satisfaction (PS) with service quality is associated with favorable survival outcomes in a variety of cancers. However, we argued that patients with greater satisfaction might be the ones with better self-rated health (SRH), a recognized predictor of cancer survival. We therefore investigated whether SRH can supersede patient satisfaction as a predictor of survival in prostate cancer. METHODS: Nine hundred seventeen prostate cancer treated at four Cancer Treatment Centers of America(®) hospitals between July 2011 and March 2013. PS was measured on a 7-point scale ranging from "completely dissatisfied" to "completely satisfied". SRH was measured on a 7-point scale ranging from "very poor" to "excellent". Both were dichotomized into two categories: top box response (7) versus all others (1-6). Patient survival was the primary end point. Cox regression was used to evaluate the association between PS and survival controlling for covariates. RESULTS: The response rate for this study was 72%. Majority of patients (n = 517) had stage II disease. Seven hundred eighty-seven (85.8%) patients were "completely satisfied". Three hundred nineteen (34.8%) patients had "excellent" SRH. There was a weak but significant correlation between satisfaction and SRH (Kendall's tau b = 0.18; p < 0.001). On univariate analysis, "completely satisfied" patients had a significantly lower risk of mortality (HR = 0.46; 95% CI: 0.25-0.85; p = 0.01). Similarly, patients with "excellent" SRH had a significantly lower risk of mortality (HR = 0.25; 95% CI: 0.11-0.58; p = 0.001). On multivariate analysis, SRH was found to be a significant predictor of survival (HR = 0.31; 95% CI: 0.12-0.79; p = 0.01) while patient satisfaction was not (HR = 0.76; 95% CI: 0.40-1.5; p = 0.40). CONCLUSIONS: SRH supersedes patient satisfaction with service quality as a predictor of survival in prostate cancer. SRH should be used as a control variable in analyses involving patient satisfaction as a predictor of clinical cancer outcomes.

RESUMEN

Budd-Chiari syndrome is a rare disorder characterised by hepatic venous outflow obstruction. It affects 1.4 per million people, and presentation depends upon the extent and rapidity of hepatic vein occlusion. An underlying myeloproliferative neoplasm is present in 50% of cases with other causes including infection and malignancy. Common symptoms are abdominal pain, hepatomegaly and ascites; however, up to 20% of cases are asymptomatic, indicating a chronic onset of hepatic venous obstruction and the formation of large hepatic vein collaterals. Doppler ultrasonography usually confirms diagnosis with cross-sectional imaging used for complex cases and to allow temporal comparison. Myeloproliferative neoplasms should be tested for even if a clear causative factor has been identified. Management focuses on anticoagulation with low-molecular-weight heparin and warfarin, with the new oral anticoagulants offering an exciting prospect for the future, but their current effectiveness in Budd-Chiari syndrome is unknown. A third of patients require further intervention in addition to anticoagulation, commonly due to deteriorating liver function or patients identified as having a poorer prognosis. Prognostic scoring systems help guide treatment, but management is complex and patients should be referred to a specialist liver centre. Recent studies have shown comparable procedure-related complications and long-term survival in patients who undergo transjugular intrahepatic portosystemic shunting and liver transplantation in Budd-Chiari syndrome compared with other liver disease aetiologies. Also, the optimal timing of these interventions and which patients benefit from liver transplantation instead of portosystemic shunting remains to be answered.

RESUMEN

OBJECTIVES: We conducted a review of the peer-reviewed literature since 2003 to catalogue reported methods of stakeholder engagement in comparative effectiveness research and patient-centered outcomes research. METHODS AND RESULTS: We worked with stakeholders before, during and after the review was conducted to: define the primary and key research questions; conduct the literature search; screen titles, abstracts and articles; abstract data from the articles; and analyze the data. The literature search yielded 2,062 abstracts. The review was conducted on 70 articles that reported on stakeholder engagement in individual research projects or programs. FINDINGS: Reports of stakeholder engagement are highly variable in content and quality. We found frequent engagement with patients, modestly frequent engagement with clinicians, and infrequent engagement with stakeholders in other key decision-making groups across the healthcare system. Stakeholder engagement was more common in earlier (prioritization) than in later (implementation and dissemination) stages of research. The roles and activities of stakeholders were highly variable across research and program reports. RECOMMENDATIONS: To improve on the quality and content of reporting, we developed a 7-Item Stakeholder Engagement Reporting Questionnaire. We recommend three directions for future research: 1) descriptive research on stakeholder-engagement in research; 2) evaluative research on the impact of stakeholder engagement on the relevance, transparency and adoption of research; and 3) development and validation of tools that can be used to support stakeholder engagement in future work.

RESUMEN

BACKGROUND: Clinical guidelines recommend that adults with hypertension self-monitor their blood pressure (BP). PURPOSE: To summarize evidence about the effectiveness of self-measured blood pressure (SMBP) monitoring in adults with hypertension. DATA SOURCES: MEDLINE (inception to 8 February 2013) and Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews (fourth quarter 2012). STUDY SELECTION: 52 prospective comparative studies of SMBP monitoring with or without additional support versus usual care or an alternative SMBP monitoring intervention in persons with hypertension. DATA EXTRACTION: Data on population, interventions, BP, other outcomes, and study method were extracted. Random-effects model meta-analyses were done. DATA SYNTHESIS: For SMBP monitoring alone versus usual care (26 comparisons), moderate-strength evidence supports a lower BP with SMBP monitoring at 6 months (summary net difference, -3.9 mm Hg and -2.4 mm Hg for systolic BP and diastolic BP) but not at 12 months. For SMBP monitoring plus additional support versus usual care (25 comparisons), high-strength evidence supports a lower BP with use of SMBP monitoring, ranging from -3.4 to -8.9 mm Hg for systolic BP and from -1.9 to -4.4 mm Hg for diastolic BP, at 12 months in good-quality studies. For SMBP monitoring plus additional support versus SMBP monitoring alone or with less intense additional support (13 comparisons), low-strength evidence fails to support a difference. Across all comparisons, evidence for clinical outcomes is insufficient. For other surrogate or intermediate outcomes, low-strength evidence fails to show differences. LIMITATION: Clinical heterogeneity in protocols for SMBP monitoring, additional support, BP targets, and management; follow-up of 1 year or less in most studies, with sparse clinical outcome data. CONCLUSION: Self-measured BP monitoring with or without additional support lowers BP compared with usual care, but the BP effect beyond 12 months and long-term benefits remain uncertain. Additional support enhances the BP-lowering effect. PRIMARY FUNDING SOURCE: Agency for Healthcare Research and Quality.

RESUMEN

Inflammatory bowel disease (IBD), comprising ulcerative colitis (UC) and Crohn's disease (CD), is a costly condition in terms of morbidity and healthcare utilization, with an increasing prevalence now approaching 1% in the Western world. Endoscopic assessment of IBD remains the gold standard for diagnosis, evaluation of treatment response and determination of post-operative recurrence, but is expensive and invasive. Biomarkers can facilitate non-invasive disease assessment, with C-reactive protein and faecal calprotectin as the most widely available biomarkers in current clinical practice. This narrative review summarizes the evidence for their use in both UC and CD and offers practical guidance for healthcare providers taking into account the limitations of biomarker interpretation. We present evidence for the future use of novel biomarkers in IBD and discuss how biomarker discovery could deliver the goal of precision medicine in IBD.


Biomarkers in inflammatory bowel disease: a practical guide Inflammatory bowel disease (IBD) is a term used to describe two conditions, ulcerative colitis (UC) and Crohn's disease (CD). These two diseases cause inflammation of the bowel, which can lead to diarrhoea, abdominal pain and bleeding from the back passage. The best way of assessing how active a patient's IBD is, is by performing a camera test called a colonoscopy. However, having a colonoscopy is inconvenient, comes with some risks to the patient, and uses a lot of healthcare resources. 'Biomarkers' are proteins detectable in body fluids (such as blood, poo and urine) which can give information to medical staff about how active a patient's disease is, without the need for colonoscopy. In this article, we give guidance about how best to use these tests, and when they might not be so useful. We also discuss new biomarkers and ways in which they could be used in the future to predict which treatments patients might respond to best.

RESUMEN

Inflammatory bowel disease (IBD) commonly requires immunosuppressive treatments to induce and maintain durable remission. Janus kinase inhibitors (JAKis) are a novel group of orally administered, small molecule drugs that work by attenuating multiple cytokine signalling pathways to mediate dysregulated immune responses involved in the pathogenesis of IBD. Tofacitinib, filgotinib and upadacitinib have demonstrated efficacy against placebo and are licensed for the treatment of moderate to severe ulcerative colitis; upadacitinib is the only JAKi also currently approved for the treatment of Crohn's disease. Safety concerns stratified by age have led to class-wide regulatory restrictions for JAKi use across all inflammatory diseases. It is important for gastroenterologists managing patients with IBD to be aware of the key pivotal trial outcomes, to identify appropriate patients in whom to commence a JAKi, and to understand the safety considerations and ways to mitigate these risks in the patients they treat. This review provides a contemporaneous overview of this emerging therapeutic class and provides a practical guide for healthcare practitioners for initiating and monitoring JAKi in IBD.

RESUMEN

INTRODUCTION: Limited data are available on the effects of treatment for advanced breast cancer (ABC) in older patients because this population has limited enrollment in clinical trials. Data generated from the prospective, noninterventional POLARIS study of patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative ABC may help bridge the gap in our understanding of the tolerability and outcomes in this vulnerable population. MATERIALS AND METHODS: We evaluated measures of geriatric impairments and activities of daily living in patients with ABC aged ≥70 years in POLARIS to evaluate the change within six months of palbociclib initiation. Geriatric impairments and activities of daily living (functional) status were assessed using the Geriatric 8 (G8) and Activities of Daily Living (ADL) screening tools. The G8, ADL, and Eastern Cooperative Oncology Group performance status (ECOG PS) scores were assessed at baseline and month six through end of treatment with palbociclib. ECOG PS scores were also stratified by G8 and ADL score severity subgroups (G8: ≤14 = impaired subgroup; >14 = not at all impaired subgroup; ADL: <18 = dependent subgroup, 18 = independent subgroup). RESULTS: At data cutoff in November 2020, of 1282 POLARIS patients of all ages, 287 (22.4%) were ≥ 70 years old and completed ≥6 months of palbociclib therapy. At baseline, 117 (45%; n = 260) of these patients had an ECOG PS score of 0, 143 (55%; n = 260) had ECOG PS score > 0, 248 (86%) had G8 scores (mean [SD] 13.6 [2.14]), and 256 (89%) had ADL scores (17.7 [1.03]) among the available 287 patients. At six months, 102 (40%; n = 255) had an ECOG PS score of 0, 153 (60%; n = 255) had ECOG PS score > 0, 198 (69%) had G8 scores (13.6 [1.99]), and 211 (74%) had ADL scores (17.6 [1.22]) among the 287 available patients. There was no mean change (standard deviation) from baseline to 6 months in mean ECOG PS scores (0.0 [0.61], P = 0.24), G8 scores (0.0 [2.17], P = 0.89), or ADL scores (0.0 [1.00], P = 0.62). DISCUSSION: In this subgroup analysis of older patients with ABC from POLARIS, functional status and impairment outcomes were preserved in older patients receiving palbociclib. G8, ADL, and ECOG PS scores were generally maintained during the first six months of palbociclib therapy. CLINICALTRIALS: govidentification number. NCT03280303.
