Serum biomarkers related to frailty predict negative outcomes in older adults with hip fracture

PURPOSE

Hip fracture is a public health problem worldwide. Traditional prognostic models do not include blood biomarkers, such as those obtained by proteomics. This study aimed to investigate the relationships between serum inflammatory biomarkers and frailty in older adults with hip fracture as well as adverse outcomes at one and three months after discharge.

METHODS

A total of 45 patients aged 75 or older who were admitted for hip fracture were recruited. At admission, a Comprehensive Geriatric Assessment (CGA) was conducted, which included a frailty assessment using the Clinical Frailty Scale (CFS). Blood samples were collected before surgery. Participants were followed up at one and three months after discharge. The levels of 45 cytokines were analyzed using a high-throughput proteomic approach. Binary logistic regression was used to determine independent associations with outcomes, such as functional recovery, polypharmacy, hospital readmission, and mortality.

RESULTS

The results showed that IL-7 (OR 0.66 95% CI 0.46-0.94, p = 0.022) and CXCL-12 (OR 0.97 95% CI 0.95-0.99, p = 0.011) were associated with better functional recovery at three months after discharge, while CXCL-8 (OR 1.07 95% CI 1.01-1.14, p = 0.019) was associated with an increased risk of readmission.

CONCLUSIONS

These findings suggest that immunology biomarkers may represent useful predictors of clinical outcomes in hip fracture patients.

The impact of erythropoiesis-stimulating agents administration concomitantly with adjuvant anti-HER2 treatments on the outcomes of patients with early breast cancer: a sub-analysis of the ALTTO study

PURPOSE

To assess whether erythropoiesis-stimulating agents (ESA) administration impacts the outcomes of patients with HER2-positive early breast cancer (EBC).

METHODS

ALTTO (NCT00490139) patients were categorized by ESA use during adjuvant anti-HER2 treatment. Disease-free-survival (DFS), overall survival (OS), and time-to-distant recurrence (TTDR) were analyzed by ESA administration, with subgroup analyses according to prognostic factors. Log-rank tests and Cox modeling were performed. Adverse events (AEs) of ESA-interest were compared.

RESULTS

Among 8381 patients recruited in ALTTO, 123 (1.5%) received ESA concomitantly with study treatment. The median age of patients receiving ESA was 54 years, 39.0% premenopausal, most had tumor size > 2 cm (56.9%), node-positive (58.5%), and positive estrogen receptor expression (61.8%). Median follow-up was shorter in the ESA group [6.1 years (IQR 5.3-7.0) vs. 6.9 years (6.0-7.1); p < 0.001]. There was no DFS difference by ESA administration (log-rank p = 0.70), with 3- and 7-year DFS of 89.2% (95% CI 81.8-93.8%) and 81.6% (71.4-88.5%) in ESA group vs. 88.3% (87.6-89.0%) and 80.0% (79.1-80.9%) in No-ESA group. In subgroup analyses, the interaction of ESA administration with menopausal status was statistically significant (unadjusted p = 0.024; stratified p = 0.033), favoring premenopausal women receiving ESA. We observed no significant association of ESA administration with OS (log-rank p = 0.57; 7-year OS in ESA 88.6% vs. 90.0% in non-ESA) or TTDR. ESA-interest AEs were experienced by eight (6.5%) patients receiving ESA and 417 (5.1%) in the No-ESA group (p = 0.41).

CONCLUSION

ESA administration to patients receiving adjuvant anti-HER2 treatment for HER2-positive EBC was safe and not associated with a negative impact on survival outcomes.

Reduced Handgrip Strength Is Associated with 1 Year-Mortality in Brazilian Frail Nonagenarians and Centenarians

The aim of the present study was to investigate the association between handgrip strength and mortality in Brazilian frail nonagenarians and centenarians. Eighty-one oldest old were included (mean age [SD]: 94.2 [3.8] years). Data on strength was assessed by handgrip strength. Mortality rate of the participants was evaluated at 1-year follow-up after the functional assessment. A logistic regression analysis was used to assess differences in categories of handgrip strength between groups regarding the mortality rate. Forty-six participants (56.8%) had reduced handgrip strength. After 1 year, there were 16 deaths. Those older adults with a low handgrip strength had higher prevalence (28.3% vs. 8.6%) and increased risk of mortality than those with preserved handgrip strength (Odds ratio=4.4, confidence interval 95% 1.1, 18.4) (p=0.042). Reduced handgrip strength is associated with higher mortality rate at 1-year follow-up in Brazilian frail nonagenarians and centenarians.

The long-term efficacy and safety of nilotinib in pediatric patients with CML: a 5-year update of the DIALOG study

The efficacy and safety of nilotinib in pediatric patients with imatinib/dasatinib resistant/intolerant (R/I) or newly diagnosed (ND) Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia in chronic phase (CML-CP) was demonstrated in the phase 2, open-label DIALOG study. In this final analysis, long-term efficacy and safety are presented for patients who completed 66 cycles (of 28 days) of treatment with nilotinib (230 mg/m2 twice daily) or discontinued early. Overall, 59 patients were enrolled and 58 were treated (R/I, n = 33; ND, n = 25; median time on treatment: 60.5 and 51.9 months, respectively). In the R/I cohort, the cumulative major molecular response (MMR; BCR::ABL1 international scale [IS] ≤ 0.1%) rate was 60.6%, and no patients had a confirmed loss of MMR. Among ND patients, the best overall MMR rate was 76.0%; 3 patients had a confirmed loss of MMR. The cumulative molecular response MR4 (BCR::ABL1IS ≤ 0.01%) and MR4.5 (BCR::ABL1IS ≤ 0.0032%) rates by 66 cycles were 27.3% and 12.1% in the R/I cohort, and 56.0% and 44.0% in the ND cohort, respectively. The safety profile of nilotinib was consistent with those of earlier reports. No on-treatment deaths occurred. These long-term (up to ∼5 years) data support the efficacy and safety of nilotinib in pediatric patients with Ph+ CML-CP. This trial was registered at www.clinicaltrials.gov.uk as #NCT01844765.

Broodstock nutritional programming differentially affects the hepatic transcriptome and genome-wide DNA methylome of farmed gilthead sea bream (Sparus aurata) depending on genetic background

BACKGROUND

Broodstock nutritional programming improves the offspring utilization of plant-based diets in gilthead sea bream through changes in hepatic metabolism. Attention was initially focused on fatty acid desaturases, but it can involve a wide range of processes that remain largely unexplored. How all this can be driven by a different genetic background is hardly underlined, and the present study aimed to assess how broodstock nutrition affects differentially the transcriptome and genome-wide DNA methylome of reference and genetically selected fish within the PROGENSA® selection program.

RESULTS

After the stimulus phase with a low fish oil diet, two offspring subsets of each genetic background received a control or a FUTURE-based diet. This highlighted a different hepatic transcriptome (RNA-seq) and genome-wide DNA methylation (MBD-seq) pattern depending on the genetic background. The number of differentially expressed transcripts following the challenge phase varied from 323 in reference fish to 2,009 in genetically selected fish. The number of discriminant transcripts, and associated enriched functions, were also markedly higher in selected fish. Moreover, correlation analysis depicted a hyper-methylated and down-regulated gene expression state in selected fish with the FUTURE diet, whereas the opposite pattern appeared in reference fish. After filtering for highly represented functions in selected fish, 115 epigenetic markers were retrieved in this group. Among them, lipid metabolism genes (23) were the most reactive following ordering by fold-change in expression, rendering a final list of 10 top markers with a key role on hepatic lipogenesis and fatty acid metabolism (cd36, pitpna, cidea, fasn, g6pd, lipt1, scd1a, acsbg2, acsl14, acsbg2).

CONCLUSIONS

Gene expression profiles and methylation signatures were dependent on genetic background in our experimental model. Such assumption affected the magnitude, but also the type and direction of change. Thus, the resulting epigenetic clock of reference fish might depict an older phenotype with a lower methylation for the epigenetically responsive genes with a negative methylation-expression pattern. Therefore, epigenetic markers will be specific of each genetic lineage, serving the broodstock programming in our selected fish to prevent and mitigate later in life the risk of hepatic steatosis through changes in hepatic lipogenesis and fatty acid metabolism.

End-of-neoadjuvant treatment circulating microRNAs and HER2-positive breast cancer patient prognosis: An exploratory analysis from NeoALTTO

Background

The absence of breast cancer cells in surgical specimens, i.e., pathological complete response (pCR), is widely recognized as a favorable prognostic factor after neoadjuvant therapy. In contrast, the presence of disease at surgery characterizes a prognostically heterogeneous group of patients. Here, we challenged circulating microRNAs (miRNAs) at the end of neoadjuvant therapy as potential prognostic biomarkers in the NeoALTTO study.

Methods

Patients treated within the trastuzumab arm (i.e., pre-operative weekly trastuzumab for 6 weeks followed by the addition of weekly paclitaxel for 12 weeks; post-operative FEC for 3 cycles followed by trastuzumab up to complete 1 year of treatment) were randomized into a training (n= 54) and testing (n= 72) set. RT-PCR-based high-throughput miRNA profile was performed on plasma samples collected at the end of neoadjuvant treatment of both sets. After normalization, circulating miRNAs associated with event free survival (EFS) were identified by univariate and multivariate Cox regression model.

Results

Starting from 23 circulating miRNAs associated with EFS in the training set, we generated a 3-circulating miRNA prognostic signature consisting of miR-185-5p, miR-146a-5p, miR-22-3p, which was confirmed in the testing set. The 3-circulating miRNA signature showed a C-statistic of 0.62 (95% confidence interval [95%CI] 0.53-0.71) in the entire study cohort. By resorting to a multivariate Cox regression model we found a statistical significant interaction between the expression values of miR-194-5p and pCR status (p.interaction =0.005) with an estimate Hazard Ratio (HR) of 1.83 (95%CI 1.14- 2.95) in patients with pCR, and 0.87 (95%CI 0.69-1.10) in those without pCR. Notably, the model including this interaction along with the abovementioned 3-circulating miRNA signature provided the highest discriminatory capability with a C-statistic of 0.67 (95%CI 0.58-0.76).

Conclusions

Circulating miRNAs are informative to identify patients with different prognosis among those with heterogeneous response after trastuzumab-based neoadjuvant treatment, and may be an exploitable tool to select candidates for salvage adjuvant therapy.

Tailored Prevention of Functional Decline through a Multicomponent Exercise Program in Hospitalized Oncogeriatric Patients: Study Protocol for a Randomized Clinical Trial

BACKGROUND

Cancer mostly affects older adults, causing a wide variety of diagnostic and therapeutic dilemmas. One of the most important moments in cancer patients is the hospitalization period, in which older patients usually remain bedridden for many hours and this may lead to the appearance of sarcopenia and disability.

METHODS

We present the research protocol for a randomized controlled trial that will analyze whether an intervention applied to older patients (≥ 65 years) who are hospitalized for acute medical conditions in an Oncology Department improves function. A total of 240 hospitalized older patients will be recruited in the Hospital Universitario de Navarra, Pamplona, Spain, and they will be randomized. The intervention consists of a multicomponent exercise training program that will take place for 4 consecutive days (2 sessions/day). The control group will receive usual hospital care, which will include physical rehabilitation when needed. The primary end point will be the change in functional capacity from baseline to hospital discharge, assessed with the Short Physical Performance Battery (SPPB). Secondary end points will be changes in cognitive and mood status, quality of life, fatigue, strength (dynamic and handgrip), pain, nutrition, length of stay, falls, readmission rate and mortality at 3 months after discharge.

RESULTS

Basal data of the patients included in the RCT are described. The foreseen recruitment will not be achieved due to the context of the Covid pandemic and the significantly different responses observed during the clinical trial in oncogeriatric patients compared to our previous experience in older adults hospitalized for medical reasons.

DISCUSSION

If our hypothesis is correct and shows that a multicomponent, individualized and progressive exercise program is an effective therapy for improving the capacity of acutely hospitalized older patients compared to usual care, a change in the current system of hospitalization may be justified in oncogeriatric patients.

Cost-Consequences Analysis Following Different Exercise Interventions in Institutionalized Oldest Old: A Pilot Study of a Randomized Clinical Trial

OBJECTIVES

to investigate the effects of two different exercise interventions on cost of care, functional capacity, falls occurrence, muscle strength, and executive function in institutionalized oldest old.

DESIGN

A pilot study of a randomized clinical trial investigating 12 months of two exercise interventions compared to a usual care group in oldest old residents of a nursing home.

SETTING AND PARTICIPANTS

69 older patients (mean age 89.4 ±5.1 years) completed the full baseline and post intervention measurements. Participants were randomly allocated into multicomponent exercise group (MG, n=23), calisthenics group (CALG, n = 23), and usual care group (UCG, n=23).

METHODS

Primary outcome was individual cost of care, and secondary outcomes included different physical and cognitive functioning tests, as well as number of falls.

RESULTS

MG reduced the cost of care compared to the pre-intervention period, with the greatest difference from baseline achieved in month 12 [mean change 95% confidence interval (CI)=-330.43 (-527.06, -133.80), P=0.006], while UCG increased this outcome, with the greatest difference from baseline observed in month 12 [mean change (95%CI)=300.00 (170.27, 429.72), P=0.013]. In addition, MG significantly improved SPPB score [mean change (95% CI) = 1.21 (0.55, 1.88), P<0.001], whereas the UCG exhibited a decline in scores [mean change (95% CI) = -1.43 (-1.90, -0.97), P<0.001]. Moreover, MG group demonstrated an improvement in the number of falls [mean change (CI 95%) = -1.0 (-1.73, -0.27), P=0.003], while no significant changes were observed in UCG. Additionally, MG exhibited a significant increase in the handgrip strength (HGS) and leg press strength (P<0.001), while a decrease was observed in UCG (P<0.001). No significant changes were observed in the CALG.

CONCLUSIONS AND IMPLICATIONS

a one-year multicomponent exercise intervention reduced the cost of care, improved functional capacity and muscle strength, as well as reduced falls in institutionalized oldest old.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

AIMS

The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation.

METHODS AND RESULTS

Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin.

CONCLUSION

The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Predictive Role of CD36 Expression in HER2-Positive Breast Cancer Patients Receiving Neoadjuvant Trastuzumab

BACKGROUND

Despite huge efforts to identify biomarkers associated with long-term clinical outcomes in patients with early-stage HER2-positive breast cancer (HER2+ BC) treated with (neo)adjuvant anti-HER2 therapy, no reliable predictors have been identified so far. Fatty acid uptake, a process mediated by the transmembrane transporter CD36, has recently emerged as a potential determinant of resistance to anti-HER2 treatments in preclinical HER2+ BC models.

METHODS

Here, we investigated the association between baseline intratumor CD36 gene expression and event-free survival in 180 patients enrolled in the phase III trial Neoadjuvant Lapatinib and/or Trastuzumab Treatment Optimization (NeoALTTO), which randomly assigned stage II-III HER2+ BC patients to receive neoadjuvant lapatinib, trastuzumab, or lapatinib-trastuzumab in combination with chemotherapy. To this aim, we selected NeoALTTO trial patients for whom pretreatment whole transcriptomic data were available. The main study results were validated in an independent cohort of patients enrolled in the neoadjuvant phase II trial NeoSphere.

RESULTS

In 180 NeoALTTO patients, high intratumor CD36 expression was independently associated with worse event-free survival in patients treated with trastuzumab-based therapy (hazard ratio [HR] = 1.72, 95% confidence interval [CI] = 1.20 to 2.46), but not with lapatinib-based (HR = 1.02, 95% CI = 0.68 to 1.53) or trastuzumab-lapatinib-based (HR = 1.08, 95% CI = 0.60 to 1.94) therapy. Among 331 NeoSphere patients evaluated, high CD36 expression was independently associated with worse patient disease-free survival in both the whole study cohort (HR = 1.197, 95% CI = 1.002 to 1.428) and patients receiving trastuzumab-based neoadjuvant therapy (HR = 1.282, 95% CI = 1.049 to 1.568).

CONCLUSIONS

High CD36 expression predicts worse clinical outcomes in early-stage HER2+ BC treated with trastuzumab-based neoadjuvant therapy.

Long-term efficacy and safety of osilodrostat in Cushing's disease: final results from a Phase II study with an optional extension phase (LINC 2)

BACKGROUND

Many patients with Cushing's disease (CD) require long-term medical therapy to control their hypercortisolism. In the core phase of a Phase II study (LINC 2; NCT01331239), osilodrostat normalized mean urinary free cortisol (mUFC) in 78.9% of patients with CD. Here, we report long-term efficacy and safety data for osilodrostat following completion of an optional extension to LINC 2.

METHODS

Adult patients with CD were enrolled in a 22-week prospective Phase II study. Patients with mUFC ≤ upper limit of normal (ULN) or receiving clinical benefit at week 22 could enter the optional extension. The proportion of complete (mUFC ≤ ULN) or partial (mUFC &gt; ULN but ≥ 50% decrease from baseline) mUFC responders was assessed over time.

RESULTS

Sixteen of 19 enrolled patients entered the extension. Median (range) osilodrostat exposure from baseline to study end was 5.4 years (0.04-6.7); median (range) average dose was 10.6 mg/day (1.1-47.9). Overall response rate (complete and partial mUFC responders) was consistently ≥ 50%. Sustained control of most cardiovascular-related parameters was observed during the extension. The long-term safety profile was consistent with that reported during the core phase. Testosterone levels (females) decreased towards baseline levels during long-term follow-up, with no new or worsening cases of hirsutism during the extension.

CONCLUSIONS

In the longest prospective study of a steroidogenesis inhibitor to date, osilodrostat provided sustained reductions in mUFC for up to 6.7 years of treatment, with no new safety signals emerging during the extension. These findings support osilodrostat as an effective long-term treatment for patients with CD.

Long-term outcomes of osilodrostat in Cushing's disease: LINC 3 study extension

OBJECTIVE

To investigate the long-term efficacy and tolerability of osilodrostat, a potent oral 11β-hydroxylase inhibitor, for treating Cushing's disease (CD).

DESIGN/METHODS

A total of 137 adults with CD and mean 24-h urinary free cortisol (mUFC) > 1.5 × upper limit of normal (ULN) received osilodrostat (starting dose 2 mg bid; maximum 30 mg bid) during the prospective, Phase III, 48-week LINC 3 (NCT02180217) core study. Patients benefiting from osilodrostat at week 48 could enter the optional extension (ending when all patients had received ≥ 72 weeks of treatment or discontinued). Efficacy and safety were assessed for all enrolled patients from the core study baseline.

RESULTS

Median osilodrostat exposure from the core study baseline to study end was 130 weeks (range 1-245) and median average dose was 7.4 mg/day (range 0.8-46.6). The reduction in mean mUFC achieved during the core was maintained during the extension and remained ≤ ULN. Of 106 patients, 86 (81%) patients who entered the extension had mUFC ≤ ULN at week 72. Improvements in cardiovascular/metabolic-related parameters, physical manifestations of hypercortisolism (fat pads, central obesity, rubor, striae, and hirsutism in females), and quality of life in the core study were also maintained or improved further during the extension. No new safety signals were reported; 15/137 (10.9%) and 12/106 (11.3%) patients discontinued for adverse events during the core and extension, respectively. Mean testosterone in females decreased towards baseline levels during the extension.

CONCLUSIONS

Data from this large, multicentre trial show that long-term treatment with osilodrostat sustains cortisol normalisation alongside clinical benefits in most patients with CD and is well tolerated.

Phase 1 Study Evaluating Pharmacokinetics and Tolerability of Ofatumumab Combined With Bendamustine in Patients With Indolent B-Cell Non-Hodgkin's Lymphoma

The pharmacokinetics (PK) and safety of ofatumumab and bendamustine alone and in combination were evaluated in patients with treatment-naive or relapsed indolent B-cell non-Hodgkin lymphoma (iNHL). Patients were randomly assigned to ofatumumab and bendamustine or ofatumumab alone. Ofatumumab PK concentration profiles and parameters were similar, alone or in combination with bendamustine. A decrease of 14% in the maximum observed plasma concentration (C_max ) and 15% in the area under the plasma concentration-time curve (AUC) from time 0 to the last measurable concentration sampling time (AUC_last ) was observed for ofatumumab coadministered with bendamustine, which was not considered clinically relevant. Bendamustine PK concentration profiles and parameters were similar with or without ofatumumab. The most frequent treatment-related adverse event was infusion-related reaction in 53% in the combination arm and 47% in the ofatumumab arm. No relevant drug-drug interaction was observed between ofatumumab and bendamustine. Ofatumumab alone or in combination with bendamustine had a manageable safety profile.

Cancer cells resist antibody-mediated destruction by neutrophils through activation of the exocyst complex

BACKGROUND

Neutrophils kill antibody-opsonized tumor cells using trogocytosis, a unique mechanism of destruction of the target plasma. This previously unknown cytotoxic process of neutrophils is dependent on antibody opsonization, Fcγ receptors and CD11b/CD18 integrins. Here, we demonstrate that tumor cells can escape neutrophil-mediated cytotoxicity by calcium (Ca2+)-dependent and exocyst complex-dependent plasma membrane repair.

METHODS

We knocked down EXOC7 or EXOC4, two exocyst components, to evaluate their involvement in tumor cell membrane repair after neutrophil-induced trogocytosis. We used live cell microscopy and flow cytometry for visualization of the host and tumor cell interaction and tumor cell membrane repair. Last, we reported the mRNA levels of exocyst in breast cancer tumors in correlation to the response in trastuzumab-treated patients.

RESULTS

We found that tumor cells can evade neutrophil antibody-dependent cellular cytotoxicity (ADCC) by Ca2+-dependent cell membrane repair, a process induced upon neutrophil trogocytosis. Absence of exocyst components EXOC7 or EXOC4 rendered tumor cells vulnerable to neutrophil-mediated ADCC (but not natural killer cell-mediated killing), while neutrophil trogocytosis remained unaltered. Finally, mRNA levels of exocyst components in trastuzumab-treated patients were inversely correlated to complete response to therapy.

CONCLUSIONS

Our results support that neutrophil attack towards antibody-opsonized cancer cells by trogocytosis induces an active repair process by the exocyst complex in vitro. Our findings provide insight to the possible contribution of neutrophils in current antibody therapies and the tolerance mechanism of tumor cells and support further studies for potential use of the exocyst components as clinical biomarkers.

Abstract P1-14-05: The impact of erythropoietin administration concomitantly with adjuvant anti-HER2 treatment on the patients’ outcome: Sub-analysis of the ALTTO study

Background: The erythropoietin (EPO) receptor activation can stimulate tumor proliferation and may be implicated in resistance to anti-HER2 therapies. EPO administration can be used for the management of chemotherapy-induced anemia. We aim to assess if EPO intake during the adjuvant anti-HER2 treatment impacts the outcomes of HER2-positive early breast cancer (EBC) patients. Methods: For this post hoc analysis of the ALTTO trial (NCT00490139), we categorized two cohorts according to the use of EPO during adjuvant anti-HER2 treatment: i) at least one EPO dose (EPO-cohort) vs ii) no EPO (non-EPO-cohort). We compared their baseline characteristics to identify potential confounders. The primary endpoint disease-free-survival (DFS), and the secondary endpoint overall survival (OS) were compared between these two cohorts, with subgroup analysis according to menopausal status, tumor characteristics, and anti-HER2 treatment. Kaplan Meier method, log-rank test, and Cox regression model adjusted for confounders were performed for DFS and OS (removal criterion p&lt;0.10). The frequency of cardiovascular and thromboembolic adverse events (AEs) of EPO interest was compared between both cohorts. Results: Out of the 8,381 patients recruited in the ALTTO trial, 123 (1.5%) received EPO concomitantly with adjuvant treatment, 59 in the single HER2 blockade (Lapatinib (L)-alone or Trastuzumab (T)-alone) and 64 in dual blockade (T→L or T+L) arms. The median age of EPO-cohort patients was 54 (range: 27-74) years, and 39% were premenopausal, while most had pathologic tumor size &gt;2 cm (56.9%), positive nodal status (58.5%), positive hormone receptor (HR) status (61.8%), and poorly differentiated or undifferentiated histologic grade (64.2%). Baseline characteristics were similar in both cohorts, except for the timing of chemotherapy, for which 93.5% of patients from the EPO-cohort were enrolled in the concurrent designs (2/2B) vs 44.2% in the non-EPO-cohort (p&lt;0.001). Median FU was 6.9 years, with 6,409 (76.5%) patients still on follow-up. For the entire ALTTO cohort, the estimated 3- and 7-year DFS were 88.3% (95% CI: 87.6% - 89.0%) and 80.1% (95% CI: 79.1% - 81.0%), respectively. No difference in DFS by EPO administration (Yes/No) was observed (log-rank p=0.70). The effect of EPO remained non-significant when controlled for the four stratification factors and all other characteristics (p=0.91). The effect of EPO administration on DFS was significant for the subgroup of premenopausal women (p=0.041), favoring the EPO-cohort, noting that this result is based on small event numbers. The interaction was found significant in Cox analysis (p=0.024), remaining significant after adjustment for important prognostic variables (p=0.032). For the entire ALTTO cohort, 758 (9.0%) deaths occurred, with 3-year OS estimate 95.7% (95% CI: 95.2% - 96.1%) and 7-year OS estimate 89.9% (89.2% - 90.6%). The OS results are consistent with those for DFS regarding the lack of a significant association with EPO and the significance (p&lt;0.10) of menopausal status and EPO interaction. In the EPO-cohort (n=123), eight (6.5%) AEs of EPO interest were recorded, while from the non-EPO-cohort (n=8,147), 417 (5.1%) reported similar AEs. Three fatal and 25 life-threatening AEs of EPO interest were recorded in the non-EPO-cohort, and none in the EPO-cohort. Conclusion: EPO administration to patients receiving adjuvant anti-HER2 treatment for HER2-positive EBC was safe and not associated with a harmful impact on survival outcomes, however the sample size of patients who received EPO is rather small. These findings contrast with data suggesting poorer outcomes with EPO, therefore further investigation of tumour microenvironment is needed to better understand these results, particularly in the premenopausal subgroup.

Could a Tailored Exercise Intervention for Hospitalised Older Adults Have a Role in the Resolution of Delirium? Secondary Analysis of a Randomised Clinical Trial

Delirium is a transient neurocognitive disorder. Nonpharmacological measures can be efficient in reducing the incidence and intensity of delirium, but there is a paucity of evidence when using a physical exercise program exclusively. This was a secondary analysis of a randomised clinical trial that provided evidence on the functional and cognitive benefits of an individualised exercise intervention in hospitalised older adults. Of the 370 patients who participated in the trial, 17.1% in the intervention group had delirium and 12.1% in the control group. After the exercise intervention, 84.6% of the patients in the intervention group showed improvement in delirium compared to 68.4% of patients in the control group. Despite the fluctuating nature of delirium,we show that it is feasible to establish individualised exercise interventions in hospitalised geriatric patients in the periods when patients are able to cooperate. Baseline functional status, measured by the Barthel Index, is a clinical marker that could help to identify those who will benefit most.

Efficacy of Antiresorptive Treatment in Osteoporotic Older Adults: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

OBJECTIVES

To investigate concerns surrounding the benefits of antiresorptive drugs in older adults, a systematic review was carried out to evaluate the efficacy of these treatments in the prevention of osteoporotic hip fractures in older adults.

DESIGN

a systematic review and meta-analysis of randomized clinical trials.

SETTING AND PARTICIPANTS

older adults ≥65 years with osteoporosis, with or without a previous fragility fracture. Studies with cancer-related and corticosteroid-induced osteoporosis, participants <65 years and no reported hip fracture were not included.

METHODS

MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, ISI Web of Science and Scopus databases were searched. The primary outcome was hip fracture, and subgroup analysis (≥75 years, with different drug types and secondary prevention) and sensitivity analysis was carried out using a GRADE evaluation. Secondary outcomes were any type of fractures, vertebral fracture, bone markers and adverse events. The risk of bias was assessment with the Cochrane risk of bias tool.

RESULTS

A total of 12 randomised controlled trials (RCTs) qualified for this meta-analysis, with 36,196 participants. Antiresorptive drugs have a statistically significant effect on the prevention of hip fracture (RR=0.70; 95%CI 0.60 to 0.81), but with a moderate GRADE quality of evidence and a high number needed to treat (NNT) of 186. For other outcomes, there is a statistically significant effect, but with a low to moderate quality of evidence. Antiresorptives showed no reduction in the risk of hip fracture in people ≥75 years. The results for different drug types, secondary prevention and sensitivity analysis are similar to the main analyses and have the same concerns.

CONCLUSIONS

Antiresorptive drugs have a statistically significant effect on preventing hip fracture but with a moderate quality (unclear/high risk of bias) and high NNT (186). This small benefit disappears in those ≥75 years, but increases in secondary prevention. More RCTs in very old osteoporotic adults are needed.

Integrated Molecular and Immune Phenotype of HER2-Positive Breast Cancer and Response to Neoadjuvant Therapy: A NeoALTTO Exploratory Analysis

BACKGROUND

Little is known about the efficacy of HER2-targeted therapy in patients with breast cancer showing different HER2-pathway dependence and immune phenotypes. Herein, we report a NeoALTTO exploratory analysis evaluating the clinical value of 22 types of tumor-infiltrating immune cells by CIBERSORT and 5 immune-related metagenes in the overall patient population, and in subgroups defined by the TRAR classifier as HER2-addicted (TRAR-low) or not (TRAR-high).

METHODS

Association of baseline TRAR, immune-related metagenes, and CIBERSORT data with pathologic complete response (pCR) and event-free survival (EFS) were assessed using logistic and Cox regression models. Corrections for multiple testing were performed by the Bonferroni method.

RESULTS

A total of 226 patients were analyzed: 80 (35%) achieved a pCR, and 64 (28%) experienced a relapse with a median follow-up of 6.7 (interquartile range 6.1-6.8) years; 108 cases were classified as TRAR-low, and 118 TRAR-high. Overall, γδ T-cell fraction [OR = 2.69; 95% confidence interval (CI), 1.40-5.18], and no immune-related metagenes were predictive of pCR. Notably, lymphocyte-specific kinase (LCK) predicted pCR to combination (OR = 2.53; 95% CI, 1.12-5.69), but not to single-agent trastuzumab or lapatinib [OR = 0.74; 95% CI, 0.45-1.22 (P _interaction = 0.01)]. Integrating LCK with γδ T cells in a multivariate model added to the discriminatory capability of clinical and molecular variables with a shift in AUC from 0.80 (95% CI, 0.74-0.86) to 0.83 (95% CI, 0.78-0.89). In TRAR-low cases, activated mast cells, IFN and MHCII were reduced, and STAT1, HCK1, and γδ T cells were associated with pCR. STAT1 was broadly associated with improved EFS regardless of pCR, and nodal status in overall (HR = 0.68; 95% CI, 0.49-0.94) and in TRAR-low cases (HR = 0.50; 95% CI, 0.30-0.86).

CONCLUSIONS

Immuno-phenotyping holds the promise to complement current predictive models in HER2-positive breast cancer and to assist in new therapeutic development.

Multicomponent exercise program in older adults with lung cancer during adjuvant/palliative treatment: A secondary analysis of an intervention study

BACKGROUND

Lung cancer is the second most prevalent common cancer in the world and predominantly affects older adults. This study aimed to examine the impact of an exercise programme in the use of health resources in older adults and to assess their changes in frailty status.

DESIGN

This is a secondary analysis of a quasi-experimental study with a non-randomized control group.

SETTING

Oncogeriatrics Unit of the Complejo Hospitalario de Navarra, Spain.

PARTICIPANTS

Newly diagnosed patients with NSCLC stage I-IV.

INTERVENTION

Multicomponent exercise programme that combined resistance, endurance, balance and flexibility exercises. Each session lasted 45-50 minutes, and the exercise protocol was performed twice a week over 10 weeks.

MEASUREMENTS

Mortality, readmissions and Visits to the Emergency Department. Change in frailty status according to Fried, VES-13 and G-8 scales.

RESULTS

26 patients completed the 10-weeks intervention (IG). Mean age in the control group (CG) was 74.5 (3.6 SD) vs 79 (3 SD) in the IG, and 78,9% were male in the IG vs 71,4% in the CG. No major adverse events or health-related issues attributable to the testing or training sessions were noted. Significant between-group differences were obtained on visits to the emergency department during the year post-intervention (4 vs 1; p:0.034). No differences were found in mortality rate and readmissions, where an increasing trend was observed in the CG compared with the IG in the latter (2 vs 0; p 0.092). Fried scale was the unique indicator that seemed to be able to detect changes in frailty status after the intervention.

CONCLUSIONS

A multicomponent exercise training programme seems to reduce the number of visits to the emergency department at one-year post-intervention in older adults with NSCLC during adjuvant therapy or palliative treatment, and is able to modify the frailty status when measured with the Fried scale.

A phase 3, randomized study of ofatumumab combined with bendamustine in rituximab-refractory iNHL (COMPLEMENT A + B study)

The standard of care for indolent non-Hodgkin lymphoma (iNHL) is rituximab, an anti-CD20 antibody, with/without chemotherapy. However, multiple relapses are common in these patients. This phase 3, randomized study compared outcomes of a combination of ofatumumab (a second-generation anti-CD20 antibody) and bendamustine, with bendamustine alone in patients unresponsive to prior rituximab-based treatment. Overall, 346 patients were randomized to receive either the combination or bendamustine alone. Bendamustine was given for ≤8 cycles and ofatumumab for ≤12 cycles. The primary end-point was progression-free survival (PFS) after 215 protocol-defined events assessed by independent review committee (IRC). Median IRC-assessed PFS was 16·7 and 13·8 months in the combination and monotherapy arms respectively [hazard ratio (HR) = 0·82; P = 0·1390]. Median overall survival (OS) was 58·2 and 51·8 months in the combination and monotherapy arms respectively (HR = 0·89, P = 0·4968). The safety profile was consistent with previous reports. Overall, 73% and 80% of patients in the combination and monotherapy arms, respectively, experienced a ≥grade 3 adverse event. The study did not meet its primary end-point. No significant improvement in PFS and OS was seen with the combination of ofatumumab and bendamustine as compared with bendamustine alone in rituximab-refractory iNHL (NCT01077518).

Long-Term Control of Urinary Free Cortisol With Osilodrostat in Patients With Cushing’s Disease: Final Results From the LINC 2 Study

Introduction: During the 22-week core LINC 2 study, the oral 11β-hydroxylase inhibitor osilodrostat normalized mean urinary free cortisol (mUFC) in 79% (15/19) of patients with Cushing’s disease. This report describes long-term LINC 2 efficacy and safety results following an optional extension. Methods: Patients receiving clinical benefit at week 22 could enter the extension (that ran until Oct 22, 2019), continuing the same osilodrostat dose; dose adjustments were permitted based on efficacy and safety. Response rate (mUFC ≤ULN [controlled] or mUFC >ULN but ≥50% decrease from baseline [BL; partially controlled]) was assessed over time. Efficacy/safety were assessed for all patients from core BL until study end. Results: Of 19 enrolled patients (female:male 14:5; mean [SD] age 36.8 years [8.4]), 16 entered the optional extension and 8 of them remained on treatment until study end. Median (range) osilodrostat exposure was 282 weeks (2-351). Mean mUFC decreased from BL (9.9 x ULN) to ≤ULN by week 4 and remained stable throughout the study. All 19 patients achieved mUFC ≤ULN at least once during the study. At each assessment up to month 70 of the extension phase, 50-88% of ongoing patients were controlled, and up to 18% were partially controlled. Mean percentage change in clinical signs from BL (mean [SD]) to last assessment were: fasting plasma glucose, -10.8% (22.1) (from BL: 105.6 mg/dL [49.2]); HbA_1c, -2.1% (9.0) (from BL: 5.7% [0.7]); systolic BP, -3.3% (12.6) (from BL: 132.6 mmHg [11.6]); diastolic BP, -2.0% (10.4) (from BL: 85.0 mmHg [6.5]); BMI, -5.9% (8.8) (from BL: 30.7 kg/m² [7.0]). Overall, 9 patients discontinued treatment (n=2 core and n=7 extension), mostly because of AEs or no longer requiring treatment (n=3 each). The most common AEs during the entire treatment period were nausea (n=10), adrenal insufficiency, and headache (both n=9). AEs related to hypocortisolism and adrenal hormone precursor accumulation occurred in 11 (mostly adrenal insufficiency, n=9) and 12 patients (mostly hypertension, n=4), respectively; most were grade 1/2 and managed with dose adjustment/interruption and/or concomitant medication. Mean (SD) plasma ACTH increased from 1.8 x ULN (0.9) at BL to 7.1 x ULN (12.3) at week 22 and 6.9 x ULN (12.6) at last assessment. Mean (SD) 11-deoxycortisol increased from 1.2 x ULN (1.3) at BL to 13.6 x ULN (12.2) at week 22 and 3.6 x ULN (4.2) at last assessment. In females, mean (SD) testosterone increased from 0.8 x ULN (0.4) at BL to 2.4 x ULN (2.1) at week 22 and 1.0 x ULN (0.9) at last assessment. Two patients, both female, reported an AE of hirsutism.

Conclusions: Rapid reductions in mUFC were sustained for up to 6 years of osilodrostat treatment and were accompanied by improvements in clinical signs of hypercortisolism. Osilodrostat was well tolerated, with no new safety signals during long-term treatment.

Non-destructive evaluation of carcass and ham traits and meat quality assessment applied to early and late immunocastrated Iberian pigs

Castration is a common practice in Iberian pigs due to their advanced age and high weight at slaughter. Immunocastration (IC) is an alternative to surgical castration that influences carcass and cut fatness. These traits need to be evaluated in vivo and postmortem. The aims of the present work were (a) to determine the relationship between ham composition measured with computed tomography (CT) and in vivo ultrasound (US) and carcass fat thickness measurements, (b) to apply these technologies to early (EIP) and late (LIP) immunocastrated Iberian pigs in order to evaluate carcass fatness and ham tissue composition and (c) to assess meat quality on these animals and to find the relationships between meat quality traits (namely, intramuscular fat (IMF)) and fat depot thicknesses. For this purpose, 20 purebred Iberian pigs were immunocastrated with three doses of Improvac ®, at either 4.5, 5.5 and 9 or 11, 12 and 14 months of age (EIP or LIP; respectively; n = 10 each) and slaughtered at 17 months of age. Fat depots were evaluated in vivo by US, in carcass with a ruler and in hams by CT. Carcass and cut yields, loin meat quality and loin acceptability by consumers were determined. Also, IMF was determined in the loin and three muscles of the ham. Carcass weight was 14.9 kg heavier in EIP vs LIP, and loin backfat thickness (US- and ruler-measured) was also greater in EIP. Similarly, CT-evaluated ham bone and fat contents were greater and smaller for EIP vs LIP, respectively. Loin and ham IMF were also greater in EIP, but the other meat quality parameters were similar. The acceptability of meat by consumers was high and it did not differ between IC protocols. Correlations between several fat depots measured with the different technologies were high. In conclusion, all these technologies allowed fat depot measurements, which were highly correlated despite being obtained at different anatomical locations.

Adjuvant Pazopanib Versus Placebo After Nephrectomy in Patients With Localized or Locally Advanced Renal Cell Carcinoma: Final Overall Survival Analysis of the Phase 3 PROTECT Trial

Most studies indicate no benefit of adjuvant therapy with VEGFR tyrosine kinase inhibitors in advanced renal cell carcinoma (RCC). PROTECT (NCT01235962) was a randomized, double-blind, placebo-controlled phase 3 study to evaluate adjuvant pazopanib in patients with locally advanced RCC at high risk of relapse after nephrectomy (pazopanib, n = 769; placebo, n = 769). The results of the primary analysis showed no difference in disease-free survival between pazopanib 600 mg and placebo. Here we report the final overall survival (OS) analysis (median follow-up: pazopanib, 76 mo, interquartile range [IQR] 66-84; placebo, 77 mo, IQR 69-85). There was no significant difference in OS between the pazopanib and placebo arms (hazard ratio 1.0, 95% confidence interval 0.80-1.26; nominal p > 0.9). OS was worse for patients with T4 disease compared to those with less advanced disease and was better for patients with body mass index (BMI) ≥30 kg/m² compared to those with lower BMI. OS was significantly better for patients who remained diseasefree at 2 yr after treatment compared with those who relapsed within 2 yr. These findings are consistent with the primary outcomes from PROTECT, indicating that adjuvant pazopanib does not confer a benefit in terms of OS for patients following resection of locally advanced RCC. PATIENT SUMMARY: In the randomized, double-blind, placebo-controlled phase 3 PROTECT study, overall survival was similar for patients with locally advanced renal cell carcinoma (RCC) at high risk of relapse after nephrectomy who received adjuvant therapy with pazopanib or placebo. Pazopanib is not recommended as adjuvant therapy following resection of locally advanced RCC. This trial is registered at Clinicaltrials.gov as NCT01235962.

Oil from transgenic Camelina sativa as a source of EPA and DHA in feed for European sea bass (Dicentrarchus labrax L.)

Aquaculture, the fastest growing food production sector cannot continue to rely on finite stocks of marine fish as the primary source of the omega-3 (n-3) long-chain polyunsaturated fatty acids (LC-PUFA), eicosapentaenoic acid (EPA; 20:5n3) and docosahexaenoic acid (DHA; 22:6n-3), for feeds. A four-month feeding trial was conducted to investigate the impact of a de novo oil, with high levels of EPA and DHA, obtained from transgenic Camelina sativa on growth performance, tissue fatty acid profiles, and expression of lipid metabolism genes when used as a replacement for fish oil in feed for European seabass (Dicentrachus labrax). Triplicate groups of 50 juvenile fish (initial weight 16.7 ± 0.92 g) per tank were fed for 4 months with one of three isolipidic and isoproteic experimental diets consisting of a standard diet containing a commercial blend of fish oil and rapeseed oil (CFO), a diet containing transgenic Camelina oil (TCO), or a blend of fish oil and rapeseed oil with enhanced levels of EPA and DHA (EFO) formulated to match the n-3 LC-PUFA profile of the TCO feed. Final weight of fish fed the GM-derived oil was not different to fish fed either CFO or EFO. Slight lower growth performance of fish fed TCO at the beginning of the trial was related to transient reduced feed intake, possibly caused by glucosinolates in the raw Camelina sativa oil. The GM-derived oil improved the nutritional quality of the fish fillet by enhancing total n-3 PUFA levels compared to the fish fed the other two feeds, and maintained flesh EPA and DHA at the same levels as in fish fed the diets containing fish oil. The metabolic response in liver and intestine was generally relatively mild although diets TCO and EFO seemed to trigger a metabolic response consisting of an up-regulation of both β-oxidation (cpt1a) and fatty acid transport (fabp1), possibly reflecting higher levels of LC-PUFA. Overall, the present study indicated that an oil of terrestrial origin, Camelina sativa, when engineered to contain high levels of EPA and DHA can replace fish oil in feeds for European seabass with no detrimental impact on growth or feed efficiency, while also maintaining or increasing tissue n-3 LC-PUFA contents.

Moderate hypofractionated post-prostatectomy radiation therapy is feasible and well tolerated: experience from a single tertiary cancer centre

PURPOSE

Conventional post-prostatectomy radiation therapy comprises 6.5-8 weeks of treatment, therefore, hypofractionated and shortened schemes arouse increasing interest. We describe our experience regarding feasibility and clinical outcome of a post-prostatectomy moderate hypofractionated image-guided radiotherapy schedule MATERIALS AND METHODS: From Oct 2015-Mar 2020, 113 patients, median age of 62 years-old (range 45-76) and prostate adenocarcinoma of low risk (30%), intermediate risk (49%) and high risk (21%) were included for adjuvant (34%) or salvage radiation therapy (66%) after radical prostatectomy (RP). All patients underwent radiotherapy with image-guided IMRT/VMAT to a total dose of 62.5 Gy in 2.5 Gy/fraction in 25 fractions. Sixteen patients (14%) received concomitant androgen deprivation therapy.

RESULTS

With a median follow-up of 29 months (range 3-60 months) all patients but three are alive. Eleven patients (10%) developed exclusive biochemical relapse while 19 patients (17%) presented macroscopically visible relapse: prostatectomy bed in two patients (2%), pelvic lymph nodes in 13 patients (11.5%) and distant metastases in four patients (4%). The 3 years actuarial rates for OS, bFRS, and DMFS were 99.1, 91.1 and 91.2%, respectively. Acute and late tolerance was satisfactory. Maximal acute genitourinary (AGU) toxicity was G2 in 8% of patients; maximal acute gastrointestinal (AGI) toxicity was G2 in 3.5% of patients; maximal late genitourinary (LGU) toxicity was G3 in 1% of patients and maximal late gastrointestinal (LGI) toxicity was G2 in 2% of patients. There were no cases of severe acute or late toxicity. No relationship was found between acute or late GI/GU adverse effects and dosimetric parameters, age, presence of comorbidities or concomitant treatments.

CONCLUSIONS

Hypofractionated radiotherapy (62.5 Gy in 25 2.5 Gy fractions) is feasible and well tolerated with low complication rates allowing for a moderate dose-escalation that offers encouraging clinical results for biochemical control and survival in patients with prostate cancer after radical prostatectomy.

International Exercise Recommendations in Older Adults (ICFSR): Expert Consensus Guidelines

The human ageing process is universal, ubiquitous and inevitable. Every physiological function is being continuously diminished. There is a range between two distinct phenotypes of ageing, shaped by patterns of living - experiences and behaviours, and in particular by the presence or absence of physical activity (PA) and structured exercise (i.e., a sedentary lifestyle). Ageing and a sedentary lifestyle are associated with declines in muscle function and cardiorespiratory fitness, resulting in an impaired capacity to perform daily activities and maintain independent functioning. However, in the presence of adequate exercise/PA these changes in muscular and aerobic capacity with age are substantially attenuated. Additionally, both structured exercise and overall PA play important roles as preventive strategies for many chronic diseases, including cardiovascular disease, stroke, diabetes, osteoporosis, and obesity; improvement of mobility, mental health, and quality of life; and reduction in mortality, among other benefits. Notably, exercise intervention programmes improve the hallmarks of frailty (low body mass, strength, mobility, PA level, energy) and cognition, thus optimising functional capacity during ageing. In these pathological conditions exercise is used as a therapeutic agent and follows the precepts of identifying the cause of a disease and then using an agent in an evidence-based dose to eliminate or moderate the disease. Prescription of PA/structured exercise should therefore be based on the intended outcome (e.g., primary prevention, improvement in fitness or functional status or disease treatment), and individualised, adjusted and controlled like any other medical treatment. In addition, in line with other therapeutic agents, exercise shows a dose-response effect and can be individualised using different modalities, volumes and/or intensities as appropriate to the health state or medical condition. Importantly, exercise therapy is often directed at several physiological systems simultaneously, rather than targeted to a single outcome as is generally the case with pharmacological approaches to disease management. There are diseases for which exercise is an alternative to pharmacological treatment (such as depression), thus contributing to the goal of deprescribing of potentially inappropriate medications (PIMS). There are other conditions where no effective drug therapy is currently available (such as sarcopenia or dementia), where it may serve a primary role in prevention and treatment. Therefore, this consensus statement provides an evidence-based rationale for using exercise and PA for health promotion and disease prevention and treatment in older adults. Exercise prescription is discussed in terms of the specific modalities and doses that have been studied in randomised controlled trials for their effectiveness in attenuating physiological changes of ageing, disease prevention, and/or improvement of older adults with chronic disease and disability. Recommendations are proposed to bridge gaps in the current literature and to optimise the use of exercise/PA both as a preventative medicine and as a therapeutic agent.

Performance of the Short Physical Performance Battery in Identifying the Frailty Phenotype and Predicting Geriatric Syndromes in Community-Dwelling Elderly

The early identification of seniors at high risk of geriatric syndromes is fundamental for targeting interventions to those who most need them. To date, the predictive value of the Short Physical Performance Battery (SPPB) for multifactorial clinical conditions has not been clearly established. Thus, the aim of the present study was to determine whether the SPPB could identify frailty and predict geriatric syndromes in community-dwelling older adults. Participants comprised men and women aged 60 years and older who participated in the Health and Well-being and Aging Survey in Colombia 2015 (n=4125, 57.6% women). A structured interview was administered to obtain socio-demographic data which included age, sex, ethnicity, socioeconomic status, and urbanicity. The study included the measurement of body mass, grip strength, SPPB, Lawton´s instrumental ADL scale, specific subjective memory complaints (SSMC), frailty phenotype (Fried and FRAIL Scale), and self-reported falls, geriatric syndromes and/or medical conditions. ROC analysis was used to examine the ability of the SPPB test to predict frailty and geriatric syndromes. The cutoff that maximized both sensitivity and specificity for the frailty phenotype was 8 points or below for men and 7 points or below for women. These cutoff values significantly predicted four geriatric syndromes in descending order: mild dementia (♂ ORajus 3.34, and ♀ ORajus 2.79), low grip strength (♂ ORajus 1.98, and ♀ ORajus 2.45), falls (♂ ORajus 1.39, and ♀ ORajus 1.49), and SSMC (♂ ORajus 1.39). In summary, the main finding of the present study was that SPPB score (i.e., ≤ 8 ♂ and ≤ 7 ♀) seems to be a useful measure for identifying the physical frailty phenotype and predicting geriatric syndromes in community-dwelling older adults.

STAT3 activation in HER2-positive breast cancers: Analysis of data from a large prospective trial

The JAK/STAT3 signaling pathway may be aberrantly activated and have various and conflicting roles in breast cancer. The current study explored prognostic implications of activated STAT3 in human epidermal growth factor receptor 2 (HER2)-positive primary breast cancers in the context of a large prospective study (ALTTO). Activated STAT3 was determined by immunohistochemical analysis of STAT3 phosphorylation (Y705) performed on the primary tumors. This analysis evaluated whether patients with activated STAT3 had disease-free survival (DFS) and overall survival (OS) different from patients without activated STAT3. A total of 5694 patients out of the 8381 patients enrolled in ALTTO were included in this analysis (67.9%), and 2634 of them (46%) had evidence of STAT3 activation (minimum tumor Allred score ≥2). The median follow-up was 6.93 years (6.85-6.97 years), at the end of which 1035 (18.18%) and 520 (9.13%) patients experienced DFS and OS events, respectively. Patients with STAT3 activation experienced improved DFS compared to those without it (multivariable hazard ratio [HR], 0.84; 95% confidence interval [CI] 0.74-0.95; P = .006). There were no group differences in OS (multivariable HR, 0.92; 95% CI 0.78-1.10; P = .37). This effect was limited to ER-positive tumors. In conclusion, these findings support the role of STAT3 activation as a marker of favorable outcome in ER-positive/HER2-positive breast cancer patients.
