Abstract OT1-02-01: A phase II study of anti-PD-1 (MK-3475) therapy in patients with metastatic inflammatory breast cancer (MIBC) or non-IBC triple negative breast cancer (non-IBC TNBC) who have achieved clinical response or stable disease to prior chemotherapy

Primary Objective: To assess the efficacy of MK-3475 as a single agent in patients with MIBC and non-IBC TNBC. The primary endpoint is disease control rate at the end of 4 months after receiving the treatment. We will also investigate the association between biomarkers in the peripheral blood and tumor tissue, safety and efficacy.

Background: The extensive invasion of lymphatic vessels by tumor emboli in patients with IBC suggests that the host immune surveillance system is suboptimal or that the tumor cells have decreased immunogenicity through immune editing to avoid detection by the host. In the immune-competent host, tumor cells must overcome both innate and adaptive immunologic defenses of the host. The PD-1 receptor-ligand interaction is a major pathway hijacked by tumors to suppress immune control. MK-3475 is a potent and highly selective humanized mAb designed to block the interaction between PD-1 and its ligands, PD-L1 and PD-L2. MK-3475 strongly enhances T lymphocyte immune responses in cultured blood cells from healthy human donors, cancer patients, and primates. Mouse anti-PD-1, as a monotherapy, demonstrated efficacy in several syngeneic mouse tumor models. To date, no specific targeted therapeutic options exist for the treatment of MIBC and TNBC. After patients achieving a clinical response to systemic therapy, the maintenance of disease control is not guaranteed. Further, our recent publication suggests that IBC has immune dysfunction. Chemotherapies can debulk the disease volume but cannot be used for maintenance due to their toxicities. Using an anti PD-1 monoclonal antibody is a promising approach for this patient population.

Study Design and Treatment Plan: This is a single arm phase II study. Up to 35 patients with HER2 negative MIBC or metastatic TN-IBC (MTNBC) who have achieved clinical response or stable disease after receiving any prior systemic therapy for metastatic/recurrent disease, and meet all other criteria will be eligible. Patients will receive MK-3475 200 mg IV every 3 weeks for up to 2 years.

Statistical Considerations: The trial will be conducted using Simon's optimal two-stage design and the rate of disease control will be estimated accordingly. It is assumed that the MK-3475 single agent will have a disease control rate of 30%. A disease control rate of 10% or lower will be considered treatment failure and the regimen will be rejected under this circumstance.

Status of the study:

Activation Date: June 2015. 13 patients have been enrolled. Enrollment continues.

Abstract OT1-02-05: A single arm phase II study of adjuvant anti-PD1 (pembrolizumab) in combination with hormonal therapy in patients with hormone receptor (HR)-positive localized inflammatory breast cancer (IBC) who did not achieve a pathological complete response (pCR) to neoadjuvant chemotherapy

Background: The pCR rate to conventional chemotherapy in hormone receptor positive IBC has historically been low (7.4% for HR+ HER2-, and 30% for HR+ HER2+), and despite the use of adjuvant endocrine therapy, the recurrence rate is still as high as 40%. To date, no targeted agent is proven to improve the efficacy of adjuvant endocrine therapy within the IBC population to improve this poor disease free survival (DFS). One plausible reason for the poor efficacy of endocrine therapy is a suppressed immune system, which allows tumor cells to avoid detection despite expression of potential immunogenic surface antigens.

Trial Design: This is a single arm trial that will enroll stage III HR+ IBC patients who have completed neoadjuvant therapy but had residual disease at mastectomy. Enrollment should be before or within 2 months of beginning endocrine therapy. Monitoring of DFS will be done with radiological imaging every 3 cycles (starting at cycle 4) as clinically indicated, per standard of care. Pembrolizumab is given on day 1 of each 21 day cycle for up to 2 years if the disease is controlled, and hormonal therapy will be administered per standard of care.

Eligibility Criteria: Clinical stage 3 IBC ER+/PR+ and HER2 negative patients who completed neoadjuvant chemotherapy and surgery with evidence of residual cancer in the breast or lymph nodes, but be clinically disease-free with good performance status at the start of study. Patients also must have adequate hematologic and organ function, and have recovered from the acute effects from prior treatments.

Specific Aims: The primary objective is to determine the disease free survival (DFS) at 2 years of patients with adjuvant therapy using Pembrolizumab in combination with standard adjuvant hormonal therapy. The secondary objective is to determine the safety and toxicity profile of this combination.

Statistical Methods: With a sample size of 37 patients, assuming that 80% are alive (20% increase from historical data) and disease-free at 2 years, and all patients are followed for >2 years after enrollment with no dropout, a 95% confidence interval around the 2-year estimate of DFS will be generated. DFS will then be compared with the historical control rate of 60% by year 2 using a one-sided exponential MLE test.

Accrual: To date we have enrolled 3 patients since activation in January 2017, and the target enrollment is 37 patients.

Vitamin D and gestational diabetes mellitus: a systematic review based on data free of Hawthorne effect

BACKGROUND

Gestational diabetes mellitus (GDM) is an increasingly prevalent disorder, associated with low blood vitamin D level.

OBJECTIVES

To evaluate the relationship between vitamin D and GDM.

SEARCH STRATEGY

EMBASE, MEDLINE, Cochrane Library and China Biology Medicine disc were searched up to May 2017. The references of previous studies were screened.

SELECTION CRITERIA

Observational studies on the relationship between vitamin D and GDM free from Hawthorne effect and randomised controlled trials of vitamin D supplementation during pregnancy for preventing or treating GDM were included.

DATA COLLECTION AND ANALYSIS

Data and information of included articles were extracted by duplicate using piloted tables. Newcastle-Ottawa Scale and Cochrane Handbook were used for quality assessment. Random-effects models were used for meta-analyses. Heterogeneity tests, sensitivity analysis and analysis of publication bias were conducted.

MAIN RESULTS

Eighty-seven observational studies and 25 randomised controlled trials involving 55 859 and 2445 women, respectively, were included. Low blood vitamin D level during pregnancy was associated with a higher risk of GDM (OR 1.850, 95% CI 1.471-2.328). Blood vitamin D level for women with GDM were lower than in the control women. Blood vitamin D level was associated with fasting plasma glucose (FPG) and homeostasis model of assessment for insulin resistance index (HOMA-IR) (r = -0.100 and r = -0.351), whereas the correlation between blood vitamin D level and fasting insulin (FINS) might be concealed by publication bias. Vitamin D intervention during pregnancy could change the blood levels of vitamin D, FINS, FPG, HOMA-IR, glutathione, C-reactive protein and lipid.

CONCLUSIONS

Low blood vitamin D level could increase the risk of GDM, and vitamin D supplementation during pregnancy could ameliorate the condition of GDM.

TWEETABLE ABSTRACT

Low blood vitamin D increases gestational diabetes mellitus (GDM) risk. Vitamin D supplementation ameliorates GDM condition.

Dose-dependent expression of claudin-5 is a modifying factor in schizophrenia

Schizophrenia is a neurodevelopmental disorder that affects up to 1% of the general population. Various genes show associations with schizophrenia and a very weak nominal association with the tight junction protein, claudin-5, has previously been identified. Claudin-5 is expressed in endothelial cells forming part of the blood-brain barrier (BBB). Furthermore, schizophrenia occurs in 30% of individuals with 22q11 deletion syndrome (22q11DS), a population who are haploinsufficient for the claudin-5 gene. Here, we show that a variant in the claudin-5 gene is weakly associated with schizophrenia in 22q11DS, leading to 75% less claudin-5 being expressed in endothelial cells. We also show that targeted adeno-associated virus-mediated suppression of claudin-5 in the mouse brain results in localized BBB disruption and behavioural changes. Using an inducible 'knockdown' mouse model, we further link claudin-5 suppression with psychosis through a distinct behavioural phenotype showing impairments in learning and memory, anxiety-like behaviour and sensorimotor gating. In addition, these animals develop seizures and die after 3-4 weeks of claudin-5 suppression, reinforcing the crucial role of claudin-5 in normal neurological function. Finally, we show that anti-psychotic medications dose-dependently increase claudin-5 expression in vitro and in vivo while aberrant, discontinuous expression of claudin-5 in the brains of schizophrenic patients post mortem was observed compared to age-matched controls. Together, these data suggest that BBB disruption may be a modifying factor in the development of schizophrenia and that drugs directly targeting the BBB may offer new therapeutic opportunities for treating this disorder.

HMPA-Catalyzed One-Pot Multistep Hydrogenation Method for the Synthesis of 1,2,3-Trisubstituted Indolines

A convenient and facile method was developed for the synthesis of 1,2,3-trisubstituted indolines. Starting from indole derivatives and ketones/aldehydes, the corresponding indoline products could be obtained with high yield by the hexamethylphosphoramide (HMPA) catalyzed indole Friedel–Crafts reaction, reduction and direct reductive amination process.

A rating scale for the severity of Guillain-Barré syndrome

INTRODUCTION

The objective of this study was to develop a rating scale to assess the severity of Guillain-Barré syndrome (GBS).

METHODS

The preliminary rating scale, which contained 11 items, was developed by the Delphi method, and data of 258 patients were collected to evaluate it. Item analysis was accomplished by 100 patients; the additional 158 patients were used to evaluate the reliability, validity, and discriminative ability of the rating scale. The structure of the rating scale was testified by the confirmatory factor analysis and also made a further evaluation by the correlation analysis.

RESULTS

The rating scale contained 10 items. The three factors mainly generalized the motor function, cranial nerve function and autonomic function. The results of reliability and validity showed that the structure of the rating scale was good (χ² =68.25, df=32, χ² /df=2.13, normed fit index (NFI)=0.919, non-normed fit index (NNFI)=0.936, comparative fit index (CFI)=0.96, a root mean square error of approximation (RMSEA)=0.085), and the Cronbach's α coefficient for the scale was .852, with the three dimensions ranging from .585 to .752.

CONCLUSION

Reliability and validity of the rating scale are all satisfied. The scale contained the main clinical presentations of GBS, and it is suitable to evaluate the severity of GBS.

Negative Differential Conductance & Hot-Carrier Avalanching in Monolayer WS2 FETs

The high field phenomena of inter-valley transfer and avalanching breakdown have long been exploited in devices based on conventional semiconductors. In this Article, we demonstrate the manifestation of these effects in atomically-thin WS2 field-effect transistors. The negative differential conductance exhibits all of the features familiar from discussions of this phenomenon in bulk semiconductors, including hysteresis in the transistor characteristics and increased noise that is indicative of travelling high-field domains. It is also found to be sensitive to thermal annealing, a result that we attribute to the influence of strain on the energy separation of the different valleys involved in hot-electron transfer. This idea is supported by the results of ensemble Monte Carlo simulations, which highlight the sensitivity of the negative differential conductance to the equilibrium populations of the different valleys. At high drain currents (>10 μA/μm) avalanching breakdown is also observed, and is attributed to trap-assisted inverse Auger scattering. This mechanism is not normally relevant in conventional semiconductors, but is possible in WS2 due to the narrow width of its energy bands. The various results presented here suggest that WS2 exhibits strong potential for use in hot-electron devices, including compact high-frequency sources and photonic detectors.

Monolithically multi-color lasing from an InGaN microdisk on a Si substrate

An optically pumped multi-color laser has been achieved using an InGaN/GaN based micro-disk with an undercut structure on a silicon substrate. The micro-disk laser has been fabricated by means of a combination of a cost-effective microsphere lithography technique and subsequent dry/wet etching processes. The microdisk laser is approximately 1 μm in diameter. The structure was designed in such a way that the vertical components of the whispering gallery (WG) modes formed can be effectively suppressed. Consequently, three clean lasing peaks at 442 nm, 493 nm and 522 nm have been achieved at room temperature by simply using a continuous-wave diode laser as an optical pumping source. Time-resolved micro photoluminescence (PL) measurements have been performed in order to further confirm the lasing by investigating the excitonic recombination dynamics of these lasing peaks. A three dimensional finite-difference-time-domain (FDTD) simulation has been used for the structure design.

Genome-wide association analysis identifies potential regulatory genes for eumelanin pigmentation in chicken plumage

Plumage color in chicken is determined by the proportion of eumelanin and pheomelanin pigmentation. As the main ingredient in plumage melanin, eumelanin plays a key role in the dark black, brown and grey coloration. However, very few studies have been performed to identify the related genes and mutations on a genome-wide scale. Herein, a resource family consisting of one backcross population and two F2 cross populations between a black roster and Yukou Brown I parent stockbreed was constructed for identification of genes related to eumelanin pigmentation. Chickens with eumelanin in their plumage were classified as the case group, and the rest were considered the control group. A genome-wide association study of this phenotype and genotypes using Affymetrix 600K HD SNP arrays in this F2 family revealed 13 significantly associated SNPs and in 10 separate genes on chromosomes 1, 2, 3 and 5. Based on previous studies in model species, we inferred that genes, including NUAK family kinase 1 (NUAK1) and sonic hedgehog (SHH), may play roles in the development of neural crest cells or melanoblasts during the embryonic period, which may also affect the eumelanin pigmentation. Our results facilitate the understanding of the genetic basis of eumelanin pigmentation in chicken plumage.

Cooperation among heterogeneous prostate cancer cells in the bone metastatic niche

The growth of disseminated tumor cells into metastatic lesions depends on the establishment of a favorable microenvironment in the stroma of the target organs. Here we show that mice treated with anakinra, an antagonist of the interleukin (IL)-1β receptor (IL-1R), or harboring a targeted deletion of IL-1R are significantly less prone to develop bone tumors when inoculated in the arterial circulation with human prostate cancer (PCa) cells expressing IL-1β. Interestingly, human mesenchymal stem cells exposed in vitro to medium conditioned by IL-1β-expressing cancer cells responded by upregulating S100A4, a marker of cancer-associated fibroblasts (CAFs), and this effect was blocked by anakinra. Analogously, the stroma adjacent to skeletal metastases generated in mice by IL-1β-expressing cancer cells showed a dramatic increase in S100A4, COX-2 and the alteration of 30 tumor-related genes as measured by Nanostring analysis. These effects were not observed in the stroma associated with the rare and much smaller metastases generated by the same cells in IL-1R knockout animals, confirming that tumor-secreted IL-1β generates skeletal CAFs and conditions the surrounding bone microenvironment. In skeletal lesions from patients with metastatic PCa, histological and molecular analyses revealed that IL-1β is highly expressed in cancer cells in which the androgen receptor (AR) is not detected (AR-), whereas this cytokine is uniformly absent in the AR-positive (AR+) metastatic cells. The stroma conditioned by IL-1β-expressing cancer cells served as a supportive niche also for coexisting IL-1β-lacking cancer cells, which are otherwise unable to generate tumors after independently seeding the skeleton of mice. This niche is established very early following tumor seeding and hints to a role of IL-1β in promoting early colonization of PCa at the skeletal level.

[The preparation and evaluation of the quality control materials for detection of platelet membrane glycoproteins by flow cytometry]

Objective: To prepare the quality control material for detection of platelet membrane glycoproteins by flowcytometry and evaluate the appearance traits, homogeneity and stability of it. Methods: Fresh platelets from the blood group O donors were fixed by the certain concentration of aldehyde solution and then washed by the imidazole buffer. After that, adding certain concentration of lyophilized protection solution into the preparations. The preparations were dispensed to be lyophilized and then were kept refrigerated in 2-8 ℃.According to the protocol of control of lyophilized biological products, the quality indicator for monitoring the prepared process, containing the appearance traits, the residual water, the platelet recovery and the rehydration quality were evaluated. The homogeneity and stability of these preparations were evaluated according to the CNAS-GL03 Guidance on evaluating the homogeneity and stability of samples used for proficiency testing and the ISO Guide 35 Reference material-general and statistical principles for certification. Results: The appearance traits and the rehydration quality of the quality control materials meeted the requirements, with the residual water distributed between 3.96% to 4.04% and the platelet recovery rate ranged from 68% to 72%.The homogeneity evaluation showed that there was no significant difference among the groups(P>0.05). The stability test indicated that the positive rate of platelet membrane glycoproteins CD42b, CD41 and CD62P of the quality control material was -0.14%, -0.14% and 0.74%, respectively, at 16 weeks after storage. There was no linear trend between the percentage of positive platelets with membrane glycoproteins and time(P>0.05). Conclusions: The quality control material for detection of platelet membrane glycoproteins by flow cytometry prepared by us meets the needs of the appearance traits, the residual water, the rehydration quality, the homogeneity and the longtime stability.It is hopeful to be used as internal quality control of the assay in clinic laboratory, the external quality assessment and proficiency evaluation.

Releasable and traceless PEGylation of arginine-rich antimicrobial peptides

This study reports a strategy to temporarily mask arginine residues within antimicrobial peptides (AMPs) with methoxy poly(ethylene glycol) (mPEG). PEGylation protects AMPs from serum proteases, and can be released at a pharmaceutically-relevant rate. Fully active and unmodified (i.e., native) AMPs are released with time.

Arginine-rich antimicrobial peptides (AMPs) are emerging therapeutics of interest. However, their applicability is limited by their short circulation half-life, caused in part by their small size and digestion by blood proteases. This study reports a strategy to temporarily mask arginine residues within AMPs with methoxy poly(ethylene glycol). Based on the reagent used, release of AMPs occurred in hours to days in a completely traceless fashion. In vitro, conjugates were insensitive to serum proteases, and released native AMP with full in vitro bioactivity. This strategy is thus highly relevant and should be adaptable to the entire family of arginine-rich AMPs. It may potentially be used to improve AMP-therapies by providing a more steady concentration of AMP in the blood after a single injection, avoiding toxic effects at high AMP doses, and reducing the number of doses required over the treatment duration.

Abstract P3-05-04: Impact of androgen receptor expression in fluoxymesterone-treated, estrogen receptor–positive metastatic breast cancer exposed to contemporary hormonal therapy

Background: The use of the nonselective androgen fluoxymesterone in patients with metastatic breast cancer (MBC) diminished after the 1960s because of its adverse events and a limited understanding of its biological effects. Although fluoxymesterone has had efficacy against tamoxifen-resistant disease in clinical studies, its role in the era of contemporary hormonal therapy is unclear. Recent studies have shown that the androgen–androgen receptor (AR) complex acts as a suppressor of estrogen receptor (ER)+ breast cancer. We hypothesized that fluoxymesterone is effective against MBC that progresses despite contemporary hormonal therapy and that the drug has more clinical benefit in patients with ER+AR+ disease than in patients with ER+AR- disease. We evaluated the survival outcomes of patients with MBC who received fluoxymesterone after contemporary hormonal therapy failed and evaluated the association between ER/AR status and survival outcomes in these patients.

Methods and Materials: We included 103 patients treated with fluoxymesterone who had already received at least one prior hormonal or cytotoxic treatment for MBC between January 1, 2000, and December 31, 2014, at a single institution. A pathologist reviewed these patients' tumors' ER and AR expression levels by immunohistochemical staining. Progression-free survival (PFS) was defined from the start of fluoxymesterone treatment to the date of disease progression or last follow-up. We used Cox regression analysis to examine univariate and multivariate correlates of PFS.

Results: Patients received a median of 3 (range: 0-10) prior hormonal therapies (aromatase inhibitors, tamoxifen, and/or fulvestrant) before fluoxymesterone. Of the 103 patients, 33 (32%) discontinued fluoxymesterone because of physician decision or adverse events, which included toxicity in 14 patients, and 70 (68%) were eligible for tumor response assessment by Response Evaluation Criteria in Solid Tumors. Of these 70 patients, 2 (3%) had a complete response, 7 (10%) had a partial response, and 21 (30%) had stable disease for at least 6 months, yielding a clinical benefit rate of 43%. The median PFS was 3.9 months (95% confidence interval: 3.2–5.3 months). The multivariate analysis revealed no significant association between PFS and the type or number of prior treatments. Thirty-nine patients (38%) had archived tumor slides available for AR staining. All 39 patients had ER+ disease; 5 had ≤1%, 5 had >1% but <10%, 18 had ≥10%, and 11 had no AR nuclear expression. AR positivity defined by the presence of any AR+ cells, ≥1% AR+ cells, or ≥10% AR+ cells was not significantly associated with survival outcome.

Conclusions: Fluoxymesterone showed objective tumor response and prolonged control of ER+ MBC refractory to contemporary endocrine therapy. The number and type of prior treatments did not impact the drug's clinical benefit, and AR+ status did not influence the clinical outcome. Fluoxymesterone should be considered for patients whose ER+ MBC progresses despite contemporary hormonal therapy, regardless of their AR status.

[An analysis of clinical characteristics and factors in Parkinson's disease patients with excessive daytime sleepiness]

OBJECTIVE

To explore the clinical characteristics and prognostic factors in patients with Parkinson's disease (PD) and excessive daytime sleepiness (EDS) and to identify whether EDS could influence the sleep architecture and sleep apnea-related parameters.

METHODS

A total of 130 PD patients were eligible and enrolled in the study.By the Epworth sleepiness scale (ESS), patients were divided into the EDS group (ESS≥10) with 61 patients and the non-EDS group (ESS<10) with 69 patients.All underwent a video-polysomnography (PSG). Clinical characteristics were mainly evaluated by the unified Parkinson's disease rating scale (UPDRS) and the Hoehn-Yahr(H-Y)stage.while other related scales were applied for evaluating depression, cognitive function, quality of sleep and quality of life.

RESULTS

A total of 61 patients (46.92%) were diagnosed as EDS (ESS≥10). Compared to the non-EDS group, the EDS group had significantly higher score of HAMD, UPDRSⅠand UPDRSⅡ, and significantly lower score of MoCA and PDQ (all P<0.05). Non-conditional logistic regression analysis showed that the scores of HAMD and UPDRSⅠ were the main prognostic factors for EDS.Significantly decreased sleep latency (SL) was found in the EDS group by PSG (P=0.008). The score of ESS was showed to be correlated with the scores of HAMD, MoCA, UPDRSⅠ, UPDRSⅡ, PDQ and SL.

CONCLUSIONS

PD patients with EDS have more severe depression and cognitive dysfunction and worse quality of life.Sleep structure is altered in those patients with decreased sleep latency.Mental status is closely associated with EDS, but not sleep apnea.

Methods for Addressing Technology-induced Errors: The Current State

OBJECTIVES

The objectives of this paper are to review and discuss the methods that are being used internationally to report on, mitigate, and eliminate technology-induced errors.

METHODS

The IMIA Working Group for Health Informatics for Patient Safety worked together to review and synthesize some of the main methods and approaches associated with technology- induced error reporting, reduction, and mitigation. The work involved a review of the evidence-based literature as well as guideline publications specific to health informatics.

RESULTS

The paper presents a rich overview of current approaches, issues, and methods associated with: (1) safe HIT design, (2) safe HIT implementation, (3) reporting on technology-induced errors, (4) technology-induced error analysis, and (5) health information technology (HIT) risk management. The work is based on research from around the world.

CONCLUSIONS

Internationally, researchers have been developing methods that can be used to identify, report on, mitigate, and eliminate technology-induced errors. Although there remain issues and challenges associated with the methodologies, they have been shown to improve the quality and safety of HIT. Since the first publications documenting technology-induced errors in healthcare in 2005, we have seen in a short 10 years researchers develop ways of identifying and addressing these types of errors. We have also seen organizations begin to use these approaches. Knowledge has been translated into practice in a short ten years whereas the norm for other research areas is of 20 years.
