Optimal adaptive group sequential design with flexible timing of sample size determination.

Flexible sample size designs, including group sequential and sample size re-estimation designs, have been used as alternatives to fixed sample size designs to achieve more robust statistical power and better trial efficiency. In this work, a new representation of sample size re-estimation design suggested by Cui et al is introduced as an adaptive group sequential design with flexible timing of sample size determination. This generalized adaptive group sequential design allows one time sample size determinat...


Application of the Pentafluorosulfanyl Group as a Bioisosteric Replacement.

The success of fluorinated molecules in drug design has led medicinal chemists to search for new fluorine-containing substituents. A major recently developed group is the pentafluorosulfanyl group. This group is stable under physiological conditions and displays unique physical and chemical properties. Currently, few synthetic methods exist that install the SF5 group, yet efforts to integrate this group into lead optimization continue unabated. Typically, the SF5 group has been used as a replacement for a t...

Improvement of Phaco Tip Geometry During Torsional Phacoemulsification.

Background Advanced cataract with hard lens nuclei frequently challenge the ophthalmologic surgeon when doing phacoemulsification. In the present study, we examined the effect of a new phaco tip design during cataract surgery. Patients and Methods 100 patients were assigned to two groups. In group 1 (50 patients), the Kelman(®) tip design (Alcon) was used during phacoemulsification, while in group 2 (50 patients), the Intrepid(®) Balanced Tip was applied. Trypan blue was used in both groups, if necessary,...


Review of Recent Methodological Developments in Group-Randomized Trials: Part 1-Design.

In 2004, Murray et al. reviewed methodological developments in the design and analysis of group-randomized trials (GRTs). We have highlighted the developments of the past 13 years in design with a companion article to focus on developments in analysis. As a pair, these articles update the 2004 review. We have discussed developments in the topics of the earlier review (e.g., clustering, matching, and individually randomized group-treatment trials) and in new topics, including constrained randomization and a ...

Review of Recent Methodological Developments in Group-Randomized Trials: Part 2-Analysis.

In 2004, Murray et al. reviewed methodological developments in the design and analysis of group-randomized trials (GRTs). We have updated that review with developments in analysis of the past 13 years, with a companion article to focus on developments in design. We discuss developments in the topics of the earlier review (e.g., methods for parallel-arm GRTs, individually randomized group-treatment trials, and missing data) and in new topics, including methods to account for multiple-level clustering and alt...

Gestalt Intervention Groups for Anxious Parents in Hong Kong: A Quasi-Experimental Design.

This study examined the impact of gestalt intervention groups for anxious Chinese parents in Hong Kong. A non-randomized control group pre-test/post-test design was adopted. A total of 156 parents participated in the project. After 4 weeks of treatment, the intervention group participants had lower anxiety levels, less avoidance of inner experiences, and more kindness towards oneself and mindfulness when compared to control group participants. However, the dimension of self-judgment remained unchanged. The ...

Patient-Reported Outcomes following Single- and Multiple-Radius Total Knee Replacement: A Randomized, Controlled Trial.

Although single-radius (SR) designs of total knee replacement (TKR) have theoretical benefits, the clinical advantage conferred by such designs is unknown. The aim of this randomized, controlled study was to compare the short-term clinical outcomes of the two design rationales. A total of 105 knees were randomized to receive either a single radius (Scorpio, Stryker; SR Group) or multiple radius (AGC, Zimmer Biomet; MR group) TKR. Patient-reported outcomes (Oxford Knee Score [OKS] and Knee Society Score [KSS...

Preferential induction of cross-group influenza A hemagglutinin stem-specific memory B cells after H7N9 immunization in humans.

Antigenic drift and shift of influenza strains underscore the need for broadly protective influenza vaccines. One strategy is to design immunogens that elicit B cell responses against conserved epitopes on the hemagglutinin (HA) stem. To better understand the elicitation of HA stem-targeted B cells to group 1 and group 2 influenza subtypes, we compared the memory B cell response to group 2 H7N9 and group 1 H5N1 vaccines in humans. Upon H7N9 vaccination, almost half of the HA stem-specific response recognize...

Vaccine-induced immune responses against both Gag and Env improve control of simian immunodeficiency virus replication in rectally challenged rhesus macaques.

The ability to control lentivirus replication may be determined, in part, by the extent to which individual viral proteins are targeted by the immune system. Consequently, defining the antigens that elicit the most protective immune responses may facilitate the design of effective HIV-1 vaccines. Here we vaccinated four groups of rhesus macaques with a heterologous vector prime/boost/boost/boost (PBBB) regimen expressing the following simian immunodeficiency virus (SIV) genes: env, gag, vif, rev, tat, and n...

Cohort Research in "Omics" and Preventive Medicine.

Cohort studies are observational studies in which the investigator determines the exposure status of subjects and then follows them for subsequent outcomes. The incidence of outcomes is observed in the exposed group and compared with that in a nonexposed group. Recently, new epidemiologic strategies have encouraged cohort research information exchange and cooperation to improve the cognition of disease etiology, such as case-cohort design and nested case-control study, which is available for "omics" data. M...

Design an anticancer copper(II) pro-drug based on the flexible IIA subdomain of human serum albumin.

Owing to the flexible IIA sub-domain of human serum albumin (HSA), we proposed to rationally design a metal agent with a leaving group, and then regulate a leaving group of metal agent to be displaced by His-242 for improving its delivery efficiency and selectivity. To confirm our hypothesis, we synthesized a copper(II) compound derived from 2-amino-5-chlorophenol 2-hydroxybenzaldehyde Schiff-base, containing a leaving group [pyridine, PRD], namely Cu(L)(PRD). The HSA complex structure revealed that Cu(L)(P...

Statistical Power for the Comparative Regression Discontinuity Design With a Nonequivalent Comparison Group.

In the "sharp" regression discontinuity design (RD), all units scoring on one side of a designated score on an assignment variable receive treatment, whereas those scoring on the other side become controls. Thus the continuous assignment variable and binary treatment indicator are measured on the same scale. Because each must be in the impact model, the resulting multi-collinearity reduces the efficiency of the RD design. However, untreated comparison data can be added along the assignment variable, and a c...

Transcanalicular laser-assisted dacryocystorhinostomy with diode laser.

This article compares the efficacy of transcanalicular laser assisted dacryocystorhinostomy (TL DCR) with conventional external dacryocystorhinostomy (Ex DCR). All patients were randomly divided into two groups - Group A included patients who underwent TL DCR and Group B included patients who underwent Ex DCR. 168 operations were done in a total of 163 patients; 79 patients in group A and 84 patients in group B. The overall success rate was 90.12% in group A and 95.40% in group B. The mean total surgical ti...

Catalysts by Design: The Power of Theory.

Theoretical design of effective catalysts, in conjunction with the identification of guiding design principles and strategies, is a Holy Grail in Chemistry. Although further progress will benefit from additional computational advances, theoretical studies have already enhanced the design of molecular electrocatalysts, photocatalysts, and enzymes.

Unconventional band inversion and intrinsic quantum spin Hall effect in functionalized group-V binary films.

Adequately understanding band inversion mechanism, one of the significant representations of topological phase, has substantial implications for design and regulation of topological insulators (TIs). Here, by identifying an unconventional band inversion, we propose an intrinsic quantum spin Hall (QSH) effect in iodinated group-V binary (ABI2) monolayers with a bulk gap as large as 0.409 eV, guaranteeing its viable application at room temperature. The nontrivial topological characters, which can be establi...

Design and Syntheses of a Series of Novel Mixed Borate and Carbonate Halides.

Combining different functional units together has been regarded as the most ideal strategy to design and synthesize new inorganic materials. Based on numerous experiments, it is successful to assemble three kinds of anion groups together and find a series of novel mixed borate and carbonate halides, Rb9[B4O5(OH)4]3(CO3)X·7H2O (X=Cl, Br and I) and K9[B4O5(OH)4]3(CO3)X·7H2O (X=OH and I). Based on the structural template of above compounds, we also obtained NaRb6[B4O5(OH)4]3X (X=OH, I) crystals through repla...

RNAblueprint: Flexible multiple target nucleic acid sequence design.

Realizing the value of synthetic biology in biotechnology and medicine requires the design of molecules with specialized functions. Due to its close structure to function relationship, and the availability of good structure prediction methods and energy models, RNA is perfectly suited to be synthetically engineered with predefined properties. However, currently available RNA design tools cannot be easily adapted to accommodate new design specifications. Furthermore, complicated sampling and optimization met...

Bayesian Randomized Clinical Trials: From Fixed to Adaptive Design.

Randomized controlled studies are the gold standard for phase III clinical trials. Using α-spending functions to control the overall type I error rate, group sequential methods are well established and have been dominating phase III studies. Bayesian randomized design, on the other hand, can be viewed as a complement instead of competitive approach to the frequentist methods. For the fixed Bayesian design, the hypothesis testing can be cast in the posterior probability or Bayes factor framework, which has ...

Novel conjugates of aminoadamantanes with carbazole derivatives as potential multitarget agents for AD treatment.

A new group of compounds, promising for the design of original multitarget therapeutic agents for treating neurodegenerative diseases, based on conjugates of aminoadamantane and carbazole derivatives was synthesized and investigated. Compounds of these series were found to interact with a group of targets that play an important role in the development of this type of diseases. First of all, these compounds selectively inhibit butyrylcholinesterase, block NMDA receptors containing NR2B subunits while maintai...

Protective effects of Tempol in an experimental ovarian ischemia-reperfusion injury model in female Wistar Albino rats.

The aim of this study was to investigate the antioxidant effects of tempol on ovarian ischemia-reperfusion injury in rats. Forty female Wistar albino rats were randomly divided into five groups: Group I: sham, Group II: ischemia (I), Group III: ischemia-reperfusion (I/R), Group IV: ischemia-reperfusion (I/R) + Tempol 30 mg/kg i.p, Group V: ischemia-reperfusion + Tempol 50 mg/kg i.p. Oxidative Stress Index (OSI) was significantly higher in the ischemia group and the I/R group compared with the sham group. Ca...

Gerontological Competencies among MSW Students: Evaluation of a Gerontology Specialization Program.

The purpose of this study was to conduct a preliminary evaluation of a gerontology specialization program (GSP) within a CSWE accredited MSW program. This study utilized a pretest/posttest design with a three-group comparison: group 1-GSP students; group 2-students from the group 1 program but not in GSP; and group 3-students at two external MSW programs with no GSPs. The overall sample comprised 220 advanced year students. A CSWE Gero-Ed Center/Hartford Partnership empirical measure was used to assess over...

First in human implantation of a novel transfemoral self-expanding transcatheter heart valve to treat pure aortic regurgitation.

The first case of a novel JenaValve design using the transfemoral approach in a 78 year old female patient with pure aortic regurgitation is described. The implantation was successfully performed with excellent haemodynamics and good clinical outcome at 6 months follow up. The technology is especially appealing in non-calcified anatomies due to the clipping mechanism that has been previously utilized in the transapical design.
