Longitudinal exploration of the delivery of care following a successful antenatal practice change intervention

Frontiers in Medicine
IntroductionThis is a secondary analysis of a stepped-wedge trial. The sustainment of evidence-based care is essential for ongoing population benefits.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

FEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Sample Size Calculation for an Individual Stepped‐Wedge Randomized Trial

Biometrical Journal
ABSTRACTIn the individual stepped‐wedge randomized trial (ISW‐RT), subjects are allocated to sequences, each sequence being defined by a control period followed by an experimental period. The total follow‐up time is the same for all sequences, but the duration of the control and experimental periods varies among sequences. To our knowledge, there is no

Stepped wedge trials with continuous recruitment require new ways of thinking [PDF]

Journal of Clinical Epidemiology, 2019
There is substantial variation in the design of stepped wedge trials. Many recruit participants continuously over time, although the methodological literature has tended not to differentiate closely between continuous recruitment and discrete sampling.

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

FEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Designing stepped wedge trials to evaluate physical activity interventions in schools: methodological considerations

International Journal of Behavioral Nutrition and Physical Activity
Background In a stepped wedge design, schools are randomised to a sequence of measurements, with each sequence transitioning to intervention status at a different time.

Design of the HIV Prevention Trials Network (HPTN) Protocol 054: A cluster randomized crossover trial to evaluate combined access to Nevirapine in developing countries [PDF]

, 2003
HPTN054 is a cluster randomized trial designed to compare two approaches to providing single dose nevirapine to HIV-seropositive mothers and their infants to prevent mother-to-child transmission of HIV in resource limited settings.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...
