Background: Bacterial vaginosis (BV) can lead to adverse pregnancy outcomes such as preterm delivery. However, it is unclear whether BV treatment during pregnancy can reduce the incidence of adverse maternal-fetal outcomes.

Methods: We performed a meticulous literature search across various databases, including PubMed, EMBASE, Web of Science, and the Cochrane Database.

Article Synopsis
  • Periodontal disease is common among pregnant women, and improving oral health may positively impact pregnancy outcomes, prompting a review of recent studies on periodontal treatments using a network meta-analysis.
  • A total of 20 studies were analyzed to assess the effectiveness of various periodontal treatment strategies on five adverse pregnancy outcomes, including preterm birth and low birth weight.
  • The analysis found that specific treatment combinations, such as scaling and root planing with chlorhexidine rinsing, significantly reduced the risk of preterm birth, suggesting important implications for oral health interventions during pregnancy.

Article Synopsis
  • The study aimed to analyze the safety profiles of suspected adverse events linked to rivaroxaban by utilizing data from the FDA Adverse Event Reporting System (FAERS) between 2014 and 2024.
  • A total of 77,384 adverse drug reaction reports were reviewed, with 86% classified as serious; the majority of serious events occurred in individuals over 65 years old, predominantly affecting gastrointestinal and nervous system health.
  • The analysis identified significant adverse effects, highlighting specific serious conditions like "Haemorrhagic arteriovenous malformation," and also noted rare but serious signals such as "Basal ganglia haematoma."

Background: Capillary electrophoresis (CE) with capacitively coupled contactless conductivity detection (CD) is widely used for water quality monitoring. However, there is currently no reported CE method for detecting total dissolved nitrogen (TDN), a crucial parameter for assessing water eutrophication. One challenge is the high sulfate concentration (100 mM) introduced during persulfate digestion, leading to overlap of nitrate (from TDN) and poor electrical stacking of nitrate in CE-CD analysis.

With the increasing demand for wireless location services, it is of great interest to reduce the deployment cost of positioning systems. For this reason, indoor positioning based on WiFi has attracted great attention. Compared with the received signal strength indicator (RSSI), channel state information (CSI) captures the radio propagation environment more accurately.

The inertial navigation system has high short-term positioning accuracy but features cumulative error. Although no cumulative error occurs in WiFi fingerprint localization, mismatching is common. A popular technique thus involves integrating an inertial navigation system with WiFi fingerprint matching.

In this paper, we propose a novel energy-efficient approach for mobile activity recognition system (ARS) to detect human activities. The proposed energy-efficient ARS, using low sampling rates, can achieve high recognition accuracy and low energy consumption. A novel classifier that integrates hierarchical support vector machine and context-based classification (HSVMCC) is presented to achieve a high accuracy of activity recognition when the sampling rate is less than the activity frequency, i.

The structural, electronic, magnetic, and elastic properties of hexagonal nickel sulfide (NiS) have been investigated comparatively by Density Functional theory (DFT) and DFT plus correction for on-site Coulomb interaction (DFT+U), in which two different exchange correlation functionals local density approximations (LDA) and general gradient approximations (GGA) in the form of Perdew-Burke-Ernzerhof (PBE) are used. Our results indicate LDA and PBE methods predict hexagonal NiS to be a paramagnetic metal whereas LDA(PBE)+U calculations with reasonable on-site Coulomb interaction energy give the antiferromagnetic insulating state of low temperature hexagonal NiS successfully. Meanwhile, compared with LDA(PBE) results, LDA(PBE)+U methods give larger lattice parameters, crystal volume, and shear constant c44, consistent with the experimental picture during high-low temperature phase transition of hexagonal NiS, in which an increase of the shear constant c44 and lattice parameters were found in the low-temperature antiferromagnetic phase.

A novel method for the simultaneous determination of cadmium(II) and copper(II) during the adsorption process onto Pseudomonas aeruginosa was developed. The concentration of the free metal ions was successfully detected by square wave anodic stripping voltammetry (SWASV) on the mercaptoethane sulfonate (MES) modified gold electrode, while the P. aeruginosa was efficiently avoided approaching to the electrode surface by the MES monolayer.

Based on density functional theory and thermodynamic model, we compile a phase diagram for the polar NiO(111) surface as a function of temperature and oxygen pressure. The electronic correlation between Ni-3d electrons has also been included in the form of GGA+U method. Consistent with recent experiments, present GGA+U calculation indicates that over a broad range of oxygen partial pressure, the most stable phases are the oxygen and Ni terminated octopolar structures, which are almost degenerate in energy.

A new method was proposed for studying antimutagenic characteristics of tea polyphenols (TP) using piezoelectric impedance analysis during the Salmonella typhimurium strain TA100 growth process in the presence of mutagen 4-methylnitrosamino-1-(3-pyridyl)-1-butanone (abbreviated NNK). Compared with the general method of antimutagenic investigation, the proposed method provided real-time, multidimensional response information about the antimutagenic characteristics during the bacterial growth process. The results showed that TP was allowed to be antimutagenic at the lowest concentration of 0.
