There isgreat global variation in the sleeping arrangements for healthy newborn infants. Bed sharingis a type of sleeping practice in which the sleeping surface (e.g. bed, couch or armchair, or some other sleeping surface) is shared between the infant and another person. The possible physiological benefits include better oxygen and cardiopulmonary stability, fewer crying episodes, less risk of hypothermia, and a longer duration of breastfeeding. On the other hand, the most important harmful effect of bed sharing is that it may increase the risk of sudden infant death syndrome (SIDS). Studies have found conflicting evidence regarding the safety and efficacy of bed sharing during infancy.

To evaluate the efficacy and safety of bed sharing, started during the neonatal period, on breastfeeding status (exclusive and total duration of breastfeeding), incidence of SIDS, rates of hypothermia, neonatal and infant mortality, and long-term neurodevelopmental outcomes.

We used the standard search strategy of Cochras) and safety. Future studies should assess outcomes such as breastfeeding status and risk of SIDS. They should also include neonates from high-income countries and low- and middle-income countries, especially those countries where bed sharing is more prevalent because of cultural practices (e.g. Asian countries).Pathogens adapted to sub-lethal acidic conditions could increase the virulence and survival ability under lethal conditions. In the aquaculture industry, feed acidifiers have been used to increase the growth of aquatic animals. However, there is limited study on the effects of acidic condition on the virulence and survival of pathogens in aquaculture. In this study, we investigated the survival ability of Vibrio parahaemolyticus at lethal acidic pH (4.0) after adapted the bacteria to sub-lethal acidic pH (5.5) for 1 hr. Our results indicated that the adapted strain increased the survival ability at lethal acidic pH invoked by an inorganic (HCl) or organic (citric) acid. RNA-sequencing (RNA-seq) results revealed that 321 genes were differentially expressed at the sub-lethal acidic pH including cadC, cadBA and groES/groEL relating to acid tolerance response (ATR), as well as genes relating to outer membrane, heat-shock proteins, phosphotransferase system and flagella system. Quantitative real-time polymerase chain reaction (qRT-PCR) confirmed that cadC and cadBA were upregulated under sub-lethal acidic conditions. The CadC protein could directly regulate the expression of cadBA to modulate the ATR in V. parahaemolyticus. RNA-seq data also indicated that 113 genes in the CadC-dependent way and 208 genes in the CadC-independent way were differentially expressed, which were related to the regulation of ATR. Finally, the motility and cytotoxicity of the sub-lethal acidic adapted wild type (WT) were significantly increased compared with the unadapted strain. Our results demonstrated that the dietary acidifiers may increase the virulence and survival of V. parahaemolyticus in aquaculture.

Intensive care unit-acquired weakness (ICUAW) is a severe neuromuscular complication of critical illness. Serum lactate is a useful biomarker in critically ill patients. The relationship between serum lactate level and ICUAW remains controversial. This study evaluated whether hyperlactacidemia (lactate level >2 mmol/L) was an independent risk factor for ICUAW in critically ill adult patients.

An observational cohort study was performed in a general multidisciplinary intensive care unit (ICU). Sixty-eight consecutive adult critically ill patients without preexisting neuromuscular disease or a poor pre-ICU functional status whose length of ICU stay was 7 or more days were evaluated. Patients were screened daily for signs of awakening. Muscle strength assessment using the Medical Research Council score was performed on the first day a patient was considered awake. PARP inhibitor Patients with clinical muscle weakness were considered to have ICUAW.

Among the 68 patients who achieved a satisfactory state of consciousness, the diagnosis of ICUAW was made in 30 patients (44.1%). After multivariate analysis, hyperlactacidemia (P=.02), Acute Physiology and Chronic Health Evaluation II score (P=.04), duration of mechanical ventilation (P=.02), and the use of norepinephrine (P=.04) were found to be significantly associated with the development of ICUAW in critically ill patients.

This study shows a number of risk factors to be significantly associated with the development of ICUAW in critically ill adults. These factors should be considered when building early prediction models or designing prevention strategies for ICUAW in future studies.

Most magnetic materials provide a consistent magnetic field over time but the direction or field strength at the microscale is not easily modulated. However, magnetostrictive materials, when coupled with ferroelectric material (i.e., strain-mediated multiferroics), can undergo magnetization reorientation due to voltage-induced strain, promising refined control of magnetization at the micrometer-scale. This work demonstrates the largest single-domain microstructures (20 µm) of Terfenol-D (Tb0.3 Dy0.7 Fe1.92 ), a material that has the highest magnetostrictive strain of any known soft magnetoelastic material. These Terfenol-D microstructures enable controlled localization of magnetic beads with sub-micrometer precision. Magnetically labeled cells are captured by the field gradients generated from the single-domain microstructures without an external magnetic field. The magnetic state on these microstructures is switched through voltage-induced strain, as a result of the strain-mediated converse magnetoelectric effect, to release individual cells using a multiferroic approach. These electronically addressable micromagnets pave the way for parallelized multiferroics-based single-cell sorting under digital control for biotechnology applications.
