BACKGROUND: Nivolumab, a monoclonal antibody of immune checkpoint programmed death 1 on T cells (PD-1), combined with ipilimumab, an immune checkpoint cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) inhibitor, as combination therapy on the one hand and nivolumab as monotherapy on the other, have both demonstrated improved efficacy compared with ipilimumab alone in the CheckMate 067 study. However, the combination resulted in a higher frequency of grade 3/4 adverse events (AEs), which could result in diminished health-related quality of life (HRQoL)...

Gerald Hlavin, Lisa V Hampson, Franz Koenig
In phase II platform trials, 'many-to-one' comparisons are performed when K experimental treatments are compared with a common control to identify the most promising treatment(s) to be selected for Phase III trials. However, when sample sizes are limited, such as when the disease of interest is rare, only a single Phase II/III trial addressing both treatment selection and confirmatory efficacy testing may be feasible. In this paper, we suggest a two-step safety selection and testing procedure for such seamless trials...

Prenatal exposure to lipopolysaccharide (LPS), which likely occurs due to infection or contact with environmental allergens during pregnancy, is a proposed risk factor that induces anxiety- and autism spectrum disorder-like behaviors in offspring. However, the molecular and behavioral changes in offspring after maternal immune activation have not been completely identified. We hypothesized that a subcutaneous injection of LPS in a pregnant mouse would induce changes in cerebral serotonin (5-HT) in parallel to the appearance of anxiety-like behaviors in the dam's offspring...

BACKGROUND AND PURPOSE: Motor rehabilitation following stroke is a demanding challenge in search for new strategies to improve outcome. Rehabilitation through action observation has been reported beneficial for older adults recovering from stroke. Early sleep session following motor learning enhanced the performance of the acquired motor skills. The purpose of this study was to examine whether an early sleep session following action observation has benefit over action observation alone in the rehabilitation of older adults after stroke...

OBJECTIVES: The pharmacodynamic effects of everolimus on gastrointestinal hormone levels have not been described in patients with pancreatic neuroendocrine tumors (pNETs). We report the effects of everolimus on gastrin and glucagon levels in patients with progressive pNET in RADIANT-1 (a single-arm phase II trial) and RADIANT-3 (a placebo-controlled, randomized, phase III trial). METHODS: Serum gastrin and glucagon levels were determined by immunoassay at baseline and at predose in subsequent treatment cycles in patients with elevated baseline hormone levels...

BACKGROUND: Current outcome measures used in upper limb myoelectric prosthesis studies include clinical tests of function and self-report questionnaires on real-world prosthesis use. Research in other cohorts has questioned both the validity of self-report as an activity assessment tool and the relationship between clinical functionality and real-world upper limb activity. Previously,(1) we reported the first results of monitoring upper limb prosthesis use. However, the data visualisation technique used was limited in scope...

OBJECTIVES: Decision-making around the use of thrombolysis for patients with intermediate-risk (submassive) PE remains challenging. Studies indicate favorable clinical outcomes with systemic thrombolytics (IV tPA), but the risk of major bleeding and hemorrhagic stroke is a deterrent. Catheter-directed thrombolysis (CDT) may be a preferable strategy, as it has been shown to have a lower risk of bleeding than systemic thrombolysis. However, a three-arm randomized control study comparing IV tPA, CDT, and anticoagulation alone, with long-term follow up, would be costly and is unlikely to be performed...

This study examines the short-term effectiveness of a relationship education program designed for military couples. Distressed couples were randomly placed in either a wait-list control group or an intervention group. We conducted training sessions before a 3-month foreign assignment, and refresher courses approximately 6-week post-assignment. We analyzed the dyadic data of 32 couples, using hierarchical linear modeling in a two-level model. Reduction in unresolved conflicts was found in the intervention group, with large pre-post effects for both partners...

The interaction of the porphyrin derivative H2TCPPSpm4, having spermine pendants in the four meso positions, with the G-quadruplex (GQ) structure formed by the DNA aptamer TGGGAG has been investigated by means of UV, electronic circular dichroism and PAGE studies. The results reported here demonstrate that the porphyrin derivative is capable of stabilizing or destabilizing the higher-ordered structures of parallel GQs, depending on the method used to reach their relative stoichiometry (titration vs. single addition)...

Type I collagen, the main component of the extracellular matrix (ECM), assembles into bundles, which are then arranged in an orderly manner in many tissues. Various in vitro methods have been developed to mimic this native characteristic to create aligned, collagen-based materials for constructing tissue-engineered organs. In this study, we examined a new strategy to enhance collagen bundle formation and fibril orientation through administration of a collagen telopeptide binding peptide (CTBP). We found that CTBP, or a double-armed CTBP-PEG-CTBP derivative, could interact with both individual collagen molecules and fibrils...

Rationale Prehospital stroke care in specialized ambulances increases thrombolysis rates, reduces alarm-to-treatment times, and improves the prehospital triage. Preliminary analyses suggest cost-effectiveness. However, scientific proof of better functional outcome compared to usual care is still lacking. Aim To prove better functional outcomes after deployment of the Stroke Emergency Mobile compared to regular ambulances. Sample size estimates A sample size of 686 patients will be required in each arm (Stroke Emergency Mobile group vs...

In light of the relevant expenses of pharmacological interventions it might be interesting to make a balance between the cost of the new drugs administered, such as EGFRIs (cetuximab and panitunumab) and the added value represented by the improvement of the clinical parameters of interest such as progression free survival (PFS). Areas Covered: The analysis was conducted to assess the effect of front-line chemotherapy on the PFS, separately, on each arm of the evaluated trials. Only phase III randomized controlled trials (RCTs) were considered...

Radiation dermatitis occurs frequently during adjuvant radiation therapy for breast cancer. Prevention of radiation dermatitis by applying various creams and ointments has a limited success, and Aqua cream which has urea as one of its active ingredients is used in many institutions as a preventive treatment. The primary goal of this study is to assess the effect of vitamin D (calcipotriol) ointment in prevention of radiodermatitis in breast cancer patients compared to Aqua cream. Twenty-three women with localized breast cancer who underwent breast-conserving surgery and opted to receive adjuvant radiotherapy to breast only were enrolled in this study...

BACKGROUND: With more than 200 million cases a year, malaria is an important global health concern, especially among pregnant women. The forested tribal areas of Andhra Pradesh, Telangana and Chhattisgarh in India are affected by malaria and by an on-going chronic conflict which seriously limits access to health care. The burden of malaria and anemia among pregnant women in these areas is unknown; moreover there are no specific recommendations for pregnant women in the Indian national malaria policy...

Ivers et al. (2012) have recently stressed the importance to both statistical power and face validity of balancing allocations to study arms on relevant covariates. While several techniques exist (e.g., minimization, pair-matching, stratification), the covariate-constrained randomization (CCR) approach proposed by Moulton (2004) is favored when clusters can be recruited prior to randomization. CCRA V1.0, a macro published by Chaudhary and Moulton (2006), provides a SAS implementation of CCR for a particular subset of possible designs (those with two arms, small numbers of strata and clusters, an equal number of clusters within each stratum, and constraints that can be expressed as absolute mean differences between arms)...
