Abstract Background The benefits of mother’s own milk (MOM) for preterm infants have been widely recognized. Many studies have shown that the rate of breastfeeding of premature infants remains very low. Although many studies use measures to promote breastfeeding, few high-quality cluster randomized controlled studies have evaluated the effectiveness of these measures. WeChat is an instant messaging software for smart terminals, and WeChat mini-programs have been widely used to promote health and self-management in China....

Abstract Background COVID-19 vaccines have been administered in many countries; however, a sufficient vaccine coverage rate is not guaranteed due to vaccine hesitancy. To improve the uptake rate of COVID-19 vaccine, it is essential to evaluate the rate of vaccine hesitancy and explore relevant factors in different populations. An urgent need is to measure COVID-19 vaccine hesitancy among different population groups, hence a validated scale for measuring COVID-19 vaccine hesitancy is necessary. The present study...

Modeling optical field propagation in highly scattering and birefringent medium is of important interest to many photonic research branches. Despite the existence of numerical electromagnetic simulation tools and beam propagation method frameworks, there has been a lack of an analytical model including the full tensor nature of birefringence, which is an essential forward-propagation tool for applications requiring efficiently iterative regularization and end-to-end designs. Here, we present an analytical tool for modeling field propagation in a...

Fungal meroterpenoids are important bioactive natural products. Their biosynthetic machineries are highly diverse, and reconstitutions lead to the production of unnatural meroterpenoids. In this study, heterologous gene expression in Aspergillus oryzae and in vitro assays elucidated the biosynthetic pathway of the orthoester-containing fungal meroterpenoid austalide F. Remarkably, the α-ketoglutarate-dependent oxygenase AstB produces the hemiacetal intermediate, and the methyltransferase AstL transfers a methyl group on it to construct the orthoester functionality. This study presents the extraordinary...

Abstract Background Hepatocellular carcinoma (HCC) is one of the deadliest cancers and is mainly developed from chronic liver diseases such as hepatitis-B infection-associated liver cirrhosis (LC).

Abstract Background Fetal skeletal dysplasia (SD) is a common congenital disability comprising a complex group of skeletal disorders with substantial clinical and genetic heterogeneity. Many of these defects are detected prenatally using ultrasound (US). However, the diagnostic accuracy of the US is limited. Methods We recruited 55 unrelated fetuses with US-detected skeletal anomalies and performed sequential tests using copy number variation sequencing, targeted skeletal gene panel sequencing, or whole exome sequencing. The detected variants were...

Methods A post hoc analysis of the Therapeutic Hypothermia after Pediatric Cardiac Arrest Out-of-Hospital (THAPCA-OH) trial was conducted. Early coagulopathy was defined as presence of at least one of the following coagulation abnormalities upon admission: international standard ratio (INR), platelets, and age-adjusted activated...

The study goal was to investigate electrocardiographic findings, including corrected QT interval (QTc), in patients aged 8 to 23 with eating disorders (EDs) at presentation, compared with an age-and sex-matched control population. We retrospectively reviewed 200 ED patients, and 200 controls. Blinded electrocardiograms (ECGs) were interpreted by an expert reader, and QT intervals corrected using the Bazett formula. Eating disorder patients were 89.5% female, with mean age 16.4 years and median percent median body mass...

Abstract Background Previously identified phenotypes of acute respiratory distress syndrome (ARDS) have been limited by a disregard for temporal dynamics. We aimed to identify longitudinal phenotypes in ARDS to test the prognostic and predictive enrichment of longitudinal phenotypes, and to develop simplified models for phenotype identification. Methods We conducted a multi-database study based on the Chinese Database in Intensive Care (CDIC) and four ARDS randomized clinical trials (RCTs). We employed latent class analysis (LCA) to...

Quantum light sources play a fundamental role in quantum technologies ranging from quantum networking to quantum sensing and computation. The development of these technologies requires scalable platforms and the recent discovery of quantum light sources in silicon represents an exciting and promising prospect for scalability. The usual process for creating color-centers in silicon involves carbon implantation into silicon followed by rapid thermal annealing. However, the dependence of critical optical properties such as the inhomogeneous broadening,...

The characterization and manipulation of the polarization states at single photon level are of great importance in research fields such as quantum information processing and quantum key distribution, where the photons are normally delivered using single mode optical fibers. To date, the demonstrated polarimetry measurement techniques based on a superconducting nanowire single photon detector (SNSPD) require the SNSPD to be either highly sensitive or highly insensitive to the photon’s polarization state, therefore placing an unavoidable...

The application of blue-phase liquid crystals (BPLCs) in optical control devices has been widely studied due to their fast response characteristics. However, the fabrication of free-standing BPLC fiber with emerging functionalities is challenging. Here, we demonstrates a free-standing fiber based on BPLC with excellent stability, flexibility and multifunction. The multi-mode fiber (MMF) end face is etched by the etching agent of buffered oxide etch (BOE), which can be fixedly connected with the free-standing BPLC fiber...

Ingestion of a foreign body (FB) is a common emergency encountered in otorhinolaryngology. In most cases, FBs pass through the digestive tract spontaneously without any serious consequences, but some of them require nonsurgical interventions, and more severe cases require surgical interventions. The types of FBs ingested may differ in different countries and regions. In adults, bones, fish bones, and dental prostheses are most commonly found in the esophagus, and most of the FBs are retained...
