Valentine JC, Morrissey CO, Tacey MA, Liew D, Patil S, Ananda-Rajah M. A population-based analysis of attributable hospitalisation costs of invasive fungal diseases in haematological malignancy patients using data linkage of state-wide registry and costing databases: 2009-2015. Mycoses 2019; 63:162-171. [PMID: 31715052 DOI: 10.1111/myc.13033] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2019] [Revised: 10/23/2019] [Accepted: 10/26/2019] [Indexed: 12/01/2022]
Abstract
BACKGROUND Invasive fungal diseases (IFD) are associated with significant treatment-related costs in patients with haematological malignancies (HM). OBJECTIVES The objectives of this study were to characterise the gross and attributable hospitalisation costs of a variety of IFD in patients with HM by linking state-wide hospital administrative and costing datasets. PATIENTS/METHODS We linked the Victorian Admitted Episodes Dataset, Victorian Cancer Registry and the Victorian Cost Data Collection from 1 July 2009 to 30 June 2015. IFD cases and uninfected controls were matched 1:1 based on age within ten years, same underlying HM and length of stay prior to IFD diagnosis. The cost difference between surviving cases and controls, indexed to 2019 Australian dollars (AUD) calculated twelve months from IFD diagnosis, was determined using Poisson and negative binomial regression (NBR). RESULTS From 334 matched pairs, the gross hospitalisation cost of cases was AUD$67 277 compared to AUD$51 158 among uninfected controls, associated with an excess median hospitalisation cost of AUD$16 119 (P < .001) attributable to IFD, approximating to USD$11 362 and €10 154 at purchasing power parity. Median attributable costs were highest for patients with invasive aspergillosis (AUD$55 642; P < .001) and mucormycosis (AUD$51 272; P = .043) followed by invasive candidiasis AUD$24 572 (P < .001). No change in median excess attributable costs was observed over the study period (P = .90) Analyses by NBR revealed a 1.36-fold increase (P < .001) in total hospitalisation costs among cases as compared to controls twelve months from IFD diagnosis. CONCLUSION Invasive aspergillosis and mucormycosis have high attributable hospitalisation costs but the overall excess IFD cost of AUD$16 119 is modest, potentially reflecting missed or miscoded fungal episodes arguing for better quality surveillance data at hospital level.

Abstract
We report the first detection of gravitational lensing due to galaxy clusters using only the polarization of the cosmic microwave background (CMB). The lensing signal is obtained using a new estimator that extracts the lensing dipole signature from stacked images formed by rotating the cluster-centered Stokes QU map cutouts along the direction of the locally measured background CMB polarization gradient. Using data from the SPTpol 500 deg^{2} survey at the locations of roughly 18 000 clusters with richness λ≥10 from the Dark Energy Survey (DES) Year-3 full galaxy cluster catalog, we detect lensing at 4.8σ. The mean stacked mass of the selected sample is found to be (1.43±0.40)×10^{14}M_{⊙} which is in good agreement with optical weak lensing based estimates using DES data and CMB-lensing based estimates using SPTpol temperature data. This measurement is a key first step for cluster cosmology with future low-noise CMB surveys, like CMB-S4, for which CMB polarization will be the primary channel for cluster lensing measurements.

Abstract
The role of cytarabine-based induction and autologous stem cell transplantation (ASCT) in front-line treatment of younger patients with mantle cell lymphoma (MCL) is well established, however the utility of intensive approaches in older patients remains unclear. This retrospective study compared first line treatment outcomes in patients aged 60 years or more, treated at six tertiary centres between 2000-2015. 70 patients included had a median age of 69 (60-91) and most (94%) demonstrated advanced stage disease. Treatment regimens included: R-CHOP-like (n = 39), alternating R-CHOP/R-DHAC (n = 10), R-HyperCVAD/R-MA (n = 7), R-CHOP/Cytarabine (Nordic Protocol) (n = 10) and other (n = 4). 16 patients underwent an ASCT. The median follow-up for surviving patients was 37 months. Compared to R-CHOP-like therapies, cytarabine-based regimens were associated with an improved overall response rate (ORR) of 70% vs 33% (p < 0.001) and overall survival (OS) (HR 0.541, [0.292-1.001], p = 0.05). No difference in efficacy between different cytarabine-based regimens was detected, but R-HyperCVAD/R-MA was associated with increased hospitalisation and transfusion requirements. Patients undergoing ASCT demonstrated an improved median OS (HR 0.108 [0.015-0.796], p = 0.029) but were significantly younger. These results reaffirm the use of cytarabine in MCL for selected patients aged over 60. Such regimens should be strongly considered for this population in frontline therapy.

Abstract
BACKGROUND Little is known about the morbidity and mortality of invasive fungal disease (IFD) at a population level. The aim of this study was to determine the incidence, trends and outcomes of IFD in all haematology-oncology patients by linking Victorian hospital data to state-based registries. METHODS Episodes of IFD complicating adult haematological malignancy (HM) and haematopoietic stem cell transplantation (HSCT) patients admitted to Victorian hospitals from 1st July 2005 to 30th June 2016 were extracted from the Victorian Admitted Episodes Dataset and linked to the date of HM diagnosis from the Victorian Cancer Registry and mortality from the Victorian Death Index. Descriptive analyses and regression modelling were used. RESULTS There were 619,702 inpatient-episodes among 32,815 HM and 1,765 HSCT-patients. IFD occurring twelve-months from HM-diagnosis was detected in 669 (2.04%) HM-patients and 111 (6.29%) HSCT-recipients, respectively. Median time to IFD-diagnosis was 3, 5, 15 and 22 months in acute myeloid leukaemia, acute lymphoblastic leukaemia, Hodgkin lymphoma and multiple myeloma, respectively. Median survival from IFD-diagnosis was 7, 7 and 3 months for invasive aspergillosis, invasive candidiasis and mucormycosis, respectively. From 2005-2016, IFD incidence decreased 0.28% per 1,000 bed-days. Fungal incidence coincided with spring peaks on time-series analysis. CONCLUSIONS Data linkage is an efficient means of evaluating the epidemiology of a rare disease, however the burden of IFD is likely underestimated, arguing for better quality hospital level surveillance data to improve management strategies.

Abstract
The objective of the study was to establish correlation of seminal and serum IGF-1 with seminal attributes, estimate antioxidant potential of IGF-1 by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays and to study the effect of IGF-1 supplementation on semen cryopreservation. For this study, buffalo bulls were divided into sub-fertile (n = 2) and normal (n = 5) on the basis of sperm mass motility and individual motility. The serum IGF-1 concentration of normal bulls was greater than in sub-fertile bulls, but there was no difference in the seminal IGF-1 concentration among the groups. The values from correlation analyses indicated that serum IGF-1 concentration is positively correlated with semen mass motility and sperm concentration. In the second experiment, IGF-1 did not have antioxidant activities when assessed with DPPH and FRAP assays. In the third experiment, the ejaculates of normal and sub-fertile bulls were cryopreserved using semen extender in which there was IGF-1 supplementation at 0 (control), 50, 100, 150, 200, 250, 350 and 450 ng/mL of extender. Supplementation of IGF-1 at 250 ng/ml resulted in improved sperm motility, longevity and membrane intactness as compared to control after cryopreservation of semen from normal buffalo bulls, but not sub-fertile bulls. In summary, serum IGF-1 concentration was correlated with sperm mass motility and concentration in buffalo bulls and supplementation of IGF-1 protected sperm during the cryopreservation process but effects were not due to direct antioxidant activity.

Abstract
Abstract
Background: Triple negative breast cancer (TNBC) is a biologically distinct subtype with high risk of early relapse, particularly for patients who do not achieve a pathological complete response (pCR) after neoadjuvant chemotherapy (NAC), with an event free survival of < 60% at 3 years. Physical disruption of tumors with cryoablation (cryo) induces inflammation and releases antigens that can activate tumor-specific immune responses. In pre-clinical studies, the combination of cryo with checkpoint inhibition augmented tumor-specific immune responses and prevented cancer recurrence. In clinical studies, the combination of pre-operative ipilimumab (ipi)- +/- nivolumab (nivo)-mediated checkpoint blockade with cryo was safely administered in women with operable, early stage breast cancer and generated intra-tumoral and systemic immune responses (NCT01502592, NCT02833233). In this multi-center, randomized study, we evaluate the disease specific impact of peri-operative ipi, nivo and cryo versus standard care in women with residual TNBC after neoadjuvant taxane-based chemotherapy (NCT03546686).
Methods:Eligible pts are aged ≥18 years, with ER, PR and HER2 negative operable tumors ≥ 1.0 cm after neoadjuvant taxane-based chemotherapy. Approximately 160 patients will be randomized to one of two arms: standard-of-care breast surgery (control arm) or ipi/nivo/cryo followed by standard-of-care breast surgery (intervention arm). Subjects randomized to the intervention arm will undergo percutaneous, ultrasound- (or MRI-) guided cryoablation with concurrent research core biopsy 7-10 days prior to surgery, and will receive a pre-operative infusion with ipilimumab at the dose of 1mg/kg IV, and nivolumab 240mg flat dose IV (1 to 5 days prior to cryoablation). After surgery, patients will receive three additional doses of nivolumab 240mg flat dose IV Q2 weeks. Adjuvant capecitabine is recommended for all participants and will be administered per standard-of-care at the treating physician's discretion. Patients will be stratified by prior platinum administration, prior anthracycline administration, and clinical nodal status (positive versus negative) at enrollment. The primary endpoint is 3-year Event Free Survival (EFS). Secondary end points include Invasive Disease-Free Survival (IDFS), Distant Disease-Free Survival (DDFS), overall survival (OS) and safety. Exploratory correlative studies will be performed on tumor and serum to characterize the immunologic impact of the intervention and to explore predictors of efficacy and toxicity.

Abstract
Abstract
Background: CIPN is a common, painful, and debilitating side effect of many standard chemotherapy regimens. Patients with CIPN typically experience paresthesia (tingling, numbness), pain, and muscle weakness, and may exhibit significant functional decline and diminished quality of life. Our prior study showed that more than half of breast cancer survivors experience persistent CIPN up to a mean duration of 5.6 years and that this symptom is associated with a doubled fall risk. There is an urgent need to identify nonpharmacological approaches to reduce CIPN symptoms and improve cancer survivors' functional outcomes. Yoga is a mind-body modality that includes stretching, flexibility, and balance training; however, little is known about its effects on symptoms and functional outcomes among cancer survivors with CIPN.
Trial Design: We are conducting a two-arm pilot randomized usual care controlled trial in breast and gynecological cancer survivors at Memorial Sloan Kettering Cancer Center (MSK), New York, NY. Eligible subjects in the intervention arm receive one-hour Hatha Yoga classes taught twice weekly for eight weeks, and practice home-based yoga for a total of 12 weeks. Subjects in the wait list control (WLC) arm continue usual care for 12 weeks, followed by eight weeks of yoga classes and home-based yoga.
Eligibility Criteria: 1) Patients with a primary diagnosis of stage I-III breast, ovarian, uterine, or endometrial cancer; 2) moderate to severe CIPN, defined by four or greater on a 0–10 Numeric Rating Scale (NRS); 3) completion of neurotoxic chemotherapy at least three months prior; 4) no changes in anti-neuropathy medications within three months of enrollment; and 5) an ECOG performance status of 0–2.
Specific Aims: The primary endpoint is safety, feasibility, and NRS changes at eight weeks (end of treatment). The secondary endpoints include the Neuropathic Pain Scale (NPS) and Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) at eight, 12, and 20 weeks.
Statistical Methods: We will accrue 40 patients to get 36 patients evaluable for the primary endpoint at eight weeks. Using an ANCOVA analysis with a sample size of 36, we will be able to detect an effect size of 00.58 standard deviations (SD) of NRS (moderate effect size) between yoga and WLC assuming a NRS correlation between pre- and post-yoga of 0.5 SD. If we assume a 10% dropout rate based on our recently completed trial, we will need to recruit 20 subjects per arm (total of 40) to fall within the precision noted in the sample size calculation. We recognize that the sample size calculation was based on detecting a moderate effect between yoga and WLC and may miss small but clinically meaningful effects that can be used to design a future trial that is sufficiently powered.
Present accrual and target accrual: 40 participants. We have accrued 25 participants as of June 2018 and anticipate accrual completion by October 2018.

Abstract
Abstract
Background: The epichaperome is a new cancer target required for tumor survival (Joshi et al. Nature Reviews Cancer 2018). PU-H71 is a synthetic, purine scaffold epichaperome inhibitor that binds to the ATP-binding site of HSP90 specifically when HSP90 is integrated into the epichaperome (Rodina et al. Nature 2016). It has demonstrated antitumor activity in multiple xenograft models. Furthermore, sequential administration of nab-paclitaxel and PU-H71 in TNBC xenograft models augmented epichaperome levels, and in turn resulted in super-synergistic drug action with ablation of xenografted tumors and cures in mice.
Methods: This is an open label phase1b study of PU-H71 + nab-paclitaxel in pts with HER2- MBC. Pts received nab-paclitaxel at a standard dose of 260mg/m2 IV Q 3weeks. PU-H71 was administered IV 6 hrs (+/-1 hr) post nab-paclitaxel Q3weeks in 2 escalating dose levels (225mg/m2 and 300 mg/m2). All pts underwent FDG PET/CT every 6 weeks. Additionally, patients had the option to enroll on a separate diagnostic PU-PET protocol to measure epichaperome expression prior to initiating treatment on the phase 1b study, wherein they received a single dose of up to 11mci of 124I-PU-H71 IV and underwent imaging at 3-4hrs and 20-24 hrs. Primary objective was to establish the MTD/RP2D of this regimen. Secondary objectives were to assess PK of PU-H71 + nab-paclitaxel and clinical efficacy. Exploratory analysis included correlation of epichaperome expression at baseline using PU-PET with tumor response.
Results: 12 patients (5 ER+/HER2- ; 7 TNBC) were enrolled (6 at 225mg/m2 of PU-H71 and 6 at 300mg/m2). Median Age: 54 yrs (range: 37-71). Median ECOG: 0. Median lines of therapy in the metastatic setting: 6 (range 1-11) including prior taxanes in 75% of pts. Most common toxicities included diarrhea G1 58%; G2 7%, G3 7%) that was easily managed with anti-diarrheal agents, G1 fatigue (25%), G1/2 peripheral neuropathy (17%), G1 hyperglycemia (67%), G1 increases in alk phos (58%), AST (50%) and ALT (42%). Hematological toxicities included G3 leukopenia (42%), G3/4 neutropenia (67%), G3 anemia (50%) and G2 thrombocytopenia (17%). There were no DLTs. 33% (4/12) had PR, 58% (7/12) achieved SD with only 1 PD at the time of first scan; 5 pts are currently ongoing including 2 TNBC pts with PR who have been on therapy > 7 months. PK data will be presented. 8/12 patients also underwent PU-PET at baseline. A higher tumor to muscle SUV ratio at 24 hrs on PU-PET predicted response and increased PU-H71 retention on PU-PET at 24 hrs correlated with a longer duration of response.
Conclusion: The RP2D of PU-H71 was 300mg/m2 with 260mg/m2 of nab-paclitaxel administered IV every 3 weeks. The regimen is well tolerated with promising clinical activity in this heavily pre-treated cohort. Tumor epichaperome expression at baseline using PU-PET has the potential to serve as a predictive biomarker of response. A Phase 2 trial of this combination along with baseline PU-PET is currently planned.

Abstract
Abstract
Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common, potentially debilitating, and dose-limiting side effect experienced by breast cancer survivors. CIPN encompasses symptoms such as pain, numbness, and tingling, which can be measured subjectively by patient-reported outcomes (PRO), or objectively by quantitative sensory testing (QST); however, little is known how QST correlates with symptom profiles measured by PRO.
Methods: We conducted a cross-sectional analysis using baseline data of two ongoing clinical trials of breast cancer survivors who experienced moderate to severe CIPN defined by pain, numbness, or tingling ratings of four or greater on a numeric rating scale (NRS) after chemotherapy completion for at least three months. PRO measures of CIPN symptoms included Neuropathic Pain Scale (NPS) and Functional Assessment of Cancer Therapy-Gynecologic Oncology Group/Neurotoxicity subscale (FACT/GOG-Ntx). QST included tactile threshold (TT) measured by Von Frey's filaments, and vibration threshold (VT) measured by biothesiometer. We ran a Spearman correlation to assess the relationship between the subjective measures (NPS and FACT/GOG-Ntx) and objective measures (TT and VT QST).
Results: We included 52 sets of baseline data on 50 unique patients; two patients were enrolled in both trials at different times. Mean age was 61 years (SD 10) and 66% were white. The mean NRS pain score was 3.9 (SD 2.8), numbness 5.7 (SD 2.2), and tingling 4.3 (SD 2.8) on a 0-10 scale. The mean NPS total score was 39.2 (SD 23.1) on a 0-100 scale, and FACT/GOG-Ntx was 26.2 (SD 6.8) on a 0-44 scale. High scores on NRS and NPS and low scores on FACT/GOG-Ntx signify more severe CIPN symptoms. See Table 1 for a summary of the correlation between two questions on FACT/GOG-Ntx on tingling/numbness in hands and feet, and NPS total score with QST. A moderate correlation was observed between FACT/GOG-Ntx and QST results, suggesting patient-reported hand and foot numbness or tingling is associated with decreased hand and foot tactile and vibration perception. NPS was positively correlated with tactile perception for the hand and foot, but not with vibration perception.

Conclusions: A mild to moderate correlation was observed between subjective and objective measurements of CIPN. As CIPN presents a diverse range of symptoms, better quantifying the subjective and objective measures of CIPN can help incorporate these tools in observational and intervention trials. Understanding the correlation between PRO and QST can help establish QST as a reliable objective measurement of CIPN symptoms, and enable targeted interventions to alleviate CIPN symptoms.

Abstract
Abstract
Background: The persistent effects on skin hydration and elasticity resulting from cytotoxic and endocrine agents used in early stages of breast cancer are poorly understood. The objective of this preliminary analysis of the CHANCE study is to describe the pattern of persistent biomechanical skin changes in non-metastatic breast cancer patients treated with cytotoxic chemotherapies and/or endocrine therapies.
Methods: This is an ongoing single-center, prospective, longitudinal cohort study of non-metastatic breast cancer patients treated with cytotoxic chemotherapies and/or endocrine therapies. Objective skin hydration and elasticity measurements of the forearm were measured using Tewameter® (TM 300; Courage & Khazaka) and Cutometer® (MPA 580; Courage & Khazaka) devices under a controlled ambient environment at baseline and 6 months after chemotherapy completion, or one year after initiation of endocrine therapy.
Results: A total of 107 patients were assessed at baseline and follow-up for transepidermal water loss (TEWL) (median age 53, range 26-82) and 106 patients for skin elasticity (median age 53.5, range 26-82). Fifty-three healthy controls were evaluated at baseline with median age 47 (range, 22-73). The mean TEWL at baseline and follow-up among patients were 6.922 g/h/m2 and 8.521 g/h/m2, respectively (p<.0001). Skin firmness (0.420 versus 0.421 mm, p=0.949) and elasticity (77.2% versus 77.4%, p=0.836) did not significantly change during follow-up. When comparing chemotherapy recipients with endocrine therapy recipients, chemotherapy patients had a mildly lower TEWL at follow-up (8.369 versus 8.928 g/h/m2, p=.247) but a greater net increase in TEWL (1.687 versus 1.359 g/h/m2, p=.5) compared to endocrine patients over the study period.
Conclusions: An increase in TEWL was observed in patients receiving cytotoxic and endocrine therapies, suggesting a deterioration of the protective skin barrier possibly attributed to these therapies. No significant changes in skin firmness or elasticity were found in this preliminary analysis. Further studies are needed to elucidate the pathophysiologic mechanisms involved in persistent skin changes after systemic breast cancer therapies.

Abstract
Background The rapidly increasing diabetes burden, reaching epidemic proportions despite decades of efforts, reflects our failure to translate the proven evidence for prevention of diabetes. Yoga, with its holistic approach, alters the habituated patterns of lifestyles and behaviour. Motivated by the accumulating evidence, the Government of India funded a large randomized controlled trial. Aims and Objectives The twin objectives were: (a) estimate the prevalence of prediabetes and diabetes through a parallel multisite stratified cluster sampling method and (b) implement NMB 2017 (niyantrita madhumeha bharata abhiyaan), a randomized control trial using yoga based lifestyle program. Materials and Methods Screening for Indian Diabetes Risk score(IDRS) was conducted in randomly selected clusters in all 7 zones (65 districts from 29 states/union territories) of India. This was followed by detailed assessments in those with known diabetes and high risk (≥60) on IDRS. Those who satisfied the selection criteria and consented were recruited for the two armed waitlisted randomized control trial. A validated remedial diabetesspecific integrated yoga lifestyle module was taught to the experimental arm by certified volunteers of Indian Yoga Association. Followup assessments were done after 3 months in both groups. In this article, we report the methodology of the trial. Results Response to door to door visits (n-240,968 adults >20yrs) in randomly selected urban and rural households for screening was 162,330; detailed assessments (A1c, lipid profile, BMI, stress, tobacco etc) were performed on 50,199 individuals. Of these 12466 (6531 yoga 5935 control) consented and for the RCT; 52% females, 48% males; 38% rural, 62% urban; BMI 21.1 ± 3.8; waist circumference 91.7 ± 11.9. A1c in diabetes subjects in yoga group was 7.63 ± 2.17 and 7.86 ± 2.13 in control group. Conclusion This unique methodology provides the evidence to implement a validated yoga life style module using yoga volunteers in all parts of the country which is an urgent need to prevent India from becoming the global capital for diabetes.
