Maintained abstinence during the first 24h of a quit attempt is a critical predictor of long-term smoking cessation. Little is known about sex differences in the very early abstinence period, particularly in the context of low- and middle-income countries (LMICs) with varying anti-smoking policies and female smoking prevalences. We examined female sex effects on one-day relapse in a cross-national sample from 12 LMICs.

Data from the Global Adult Tobacco Survey (2008-2012) included nationally representative samples from 12 LMICs restricted to smokers with≥1 quit attempt in the past 12months (n=16,576). We ran adjusted logistic regression models for female sex effects on one-day relapse, adjusting for nine individual-level demographics (e.g., age, education, age at smoking initiation) and smoking cessation variables (e.g., exposure to health warnings, receipt of counseling). We then conducted a meta-analysis adjusted for national-level and policy measures through meta-regression (e.g., cigarette consumptiontinence phase of smoking cessation in LMICs.

The first day of a quit attempt is more challenging for women than men in LMICs. Tailored interventions incorporating national policies, in addition to counseling and pharmacotherapy, could play an essential role in supporting women during the initial abstinence phase of smoking cessation in LMICs.

The aim of this work is to identify the correlation between serum brain natriuretic peptide (BNP) and left ventricle (LV) systolic and diastolic function in hypertensive pregnancy disorders (HPD) through echocardiographic parameters.

Eighty-seven pregnant patients were included, 23 with normotensive pregnancy (NP), 28 with gestational hypertension (GH) and 36 with preeclampsia (PE). Conventional 2D echocardiography was used to evaluate systolic and diastolic function such as E/a, E/e', LV mass index, LV ejection fraction, as well as left atria (LA) diameters, LA indexed volume, LV strain and LA strain (LAS). Brain natriuretic levels (BNP) blood levels were also determined.

The serum levels of BNP were higher in patients with PE [median (interquartile range, IQR)] 189 (142-215) pg/ml and GH 105 (46-162) pg/ml compared to NP 23 (9-33) pg/ml, (p=0.001). BNP levels had a negative correlation with LAS (Rho=-0.79, p<0.001). Preeclampsia patients had lower LAS [median (IQR)] 22% (20%-24%) compared to the GH group 23% (20%-24%) and NP 35% (34% -35%), p=0.001. Classification and Regression Trees multivariate analysis found patterns that define trends to form mutually excluding homogeneous groups such as a) First parameter that separates 2 groups is septal e>8.2 or<8.2b), BNP serum levels above 89pg/ml, and c) LAS increases the discriminatory performance to detect and define the diastolic dysfunction or not.

At least one third of women with HPD had moderate diastolic dysfunction. The degree of diastolic dysfunction was negatively correlated with serum BNP levels and severity of HPD. LAS increase discriminatory performance to identify diastolic dysfunction in HPD.

Situation-Background-Assessment-Recommendation reporting is a structured communication tool. In other studies of simulation-based education, learning was found to increase with increases in the level of flow during scenarios. Also, communication using SBAR was found to facilitate more focus on clinical situations. However, the generalizability of those findings in nursing education and the specific benefits of combining SBAR with simulation remain unclear.

The aims of this study are to incorporate SBAR reporting into simulation-based nurse education, and measure its effects on the students' flow, communication competence, and communication self-efficacy among nursing students, to collect basic data for the development of effective nursing curricula.

This study used a non-equivalent, quasi-experimental pre-post parallel design.

The intervention was administered in a simulation center at a nursing school in South Korea.

One hundred and twenty fourth-year nursing students were recruited through convenience sampling.

The participants were quasi-randomly allocated to the control (n = 52) and SBAR (n = 68) groups. The integrated simulation course was conducted twice each week. Learning and reporting SBAR was included as a component of simulation-based education for the intervention group in each session (three scenarios). The dependent variables were communication competence, communication self-efficacy, and flow in the simulation.

SBAR did not affect communication competence or communication self-efficacy in simulation-based education. In contrast, while flow increased in both groups, the increase was greater in the SBAR group.

SBAR can increase nursing students' flow in simulations. Further studies should focus on how SBAR during simulation-based education affects nursing students' practical competency.

However, as most L. innocua strains are non-pathogenic, it has been proposed as a surrogate organism for determining the efficacy of antimicrobial strategies against L. monocytogenes. Teichoic acids are one of the three major cell wall components of Listeria, along with the peptidoglycan backbone and cell wall-associated proteins. The polymeric teichoic acids make up the majority of cell wall carbohydrates; the type of teichoic acids directly attached to the peptidoglycan are termed wall teichoic acids (WTAs). WTAs play vital physiological roles, are important virulence factors, antigenic determinants, and phage-binding ligands. The structures of the various WTAs of L. monocytogenes are well known, whereas those of L. innocua are not. In the present study, the WTA structure of L. innocua ŽM39 was determined mainly by 1D and 2D NMR spectroscopy and it was found to be the following [→4)-[α-D-GlcpNAc-(1→3)]-β-D-GlcpNAc-(1→4)-D-Rbo-(1P→]n This structure is new with respect to all currently known Listeria WTAs and it shares structural similarities with type II WTA serovar 6a. In addition, the genome of strain L. innocua ŽM39 was sequenced and the majority of putative WTA synthesis genes were identified.Mycotoxins, including zearalenone, are important natural products produced by fungi that occasionally contaminate agricultural commodities and pose serious health risks to consumers of food and feed. Zearalenone and its metabolite, α-zearalanol, are of significant concern due to their estrogenic and anabolic steroid activity. Several governments have regulatory standards and advisory guidelines for zearalenone and α-zearalanol. Raman and ultraviolet spectroscopy were employed with density functional theory methods to evaluate spectroscopic properties to distinguish between zearalenone and α-zearalanol systematically. Raman bands were assigned based on vibrational frequency calculations. A portable Raman spectroscopy instrument (785 nm laser) distinguished between zearalenone and α-zearalanol in a label-free manner. Many vibrational bands of zearalenone and α-zearalanol are similar, including high-intensity peaks at 1315 cm-1 and 1650 cm-1. However, the intensities in the Raman spectra at 1465 cm-1, 1495 cm-1, and 1620 cm-1 enabled the identification of zearalenone. The Raman peak at 1450 cm-1 is associated with α-zearalanol. These vibrational bands serve as spectral indicators to differentiate between the structurally similar zearalenone and α-zearalanol.A novel photoluminescent Hcy-AuNCs has been developed through one-pot reduction method, to establish a tobramycin sensing by second-order scattering (SOS). Hcy-AuNCs could spontaneously assemble to small-scaled aggregation, resulting in remarkable intensity enhancement of scattered luminescence signals. The luminescence of Hcy-AuNCs could be clearly observed under ultraviolet lamp, when excited at 365 nm, a significant luminescent intensity at 741 nm was monitored in SOS spectra. The introduction of AuNPs would cause large-scaled aggregation of Hcy-AuNCs that was rapidly settled in the solution, resulting in the decrease of SOS intensity. Besides, the non-radiative energy transfer between AuNPs and Hcy-AuNCs would also reduce the luminescent intensity. However, the addition of tobramycin would cause the aggregation of AuNPs due to the electrostatic and covalent bonding between AuNPs and tobramycin, thus eliminating the interference of AuNPs. The luminescence of Hcy-AuNCs reappeared, exhibiting an optical response toward tobramycin. The good linearity was obtained in a wide range from 4 nM to 300 nM with a low detection limit of 0.27 nM. The selectivity was acceptable toward different types of antibiotics. Finally, the proposed method was successfully applied to the widely used tobramycin eye drops.The infrared (IR) spectra of fentanyl, carfentanil and remifentanil, and protonated salts, are computed using quantum chemistry methods. New experimental FTIR spectra are also reported and compared to the calculations. The accuracy of two density functional theory methods, B3LYP and M06-2X, are tested against higher level theories (MP2) and the experimental data. Gas phase IR spectra are calculated for both the neutral and protonated molecules in order to compare with the experimental data measured for various salts of fentanyl and its analogues. Key vibrational modes are selected and studied in detail using a vibrational mode locality calculation. The main contributing atomic movements in these vibrational modes are identified.Dinitriles with a saturated hydrocarbon skeleton and a -C≡N group at each end can have large electric dipole moments. Their formation can be related to highly reactive radicals such as CH2CN, C2N, or CN. Thus, these saturated dinitriles are potential candidates to be observed in the interstellar medium. In this work, two members of this family, hexanedinitrile and heptanedinitrile, have been investigated through their rotational spectra. The jet-cooled broadband chirped-pulse Fourier transform microwave spectra of both molecules were measured in the 2-8 GHz frequency region. Three and six conformers of hexanedinitrile and heptanedinitrile, respectively, were detected and assigned based on the rotational and quadrupole coupling constants.Plasmon-enhanced photocatalysis has attracted considerable attention due to its low energy consumption and high energy throughput. click here Surface-enhanced Raman scattering (SERS) is a highly sensitive and label-free nondestructive tool to investigate plasmon-driven photocatalytic reactions. Herein, we present a facile method to fabricate gap-controlled Ag nanoparticle (NP) arrays with uniform and high-density distribution of hot spots, which can be employed as both efficient plasmonic photocatalysts and stable SERS platforms. The plasmon-driven catalytic reaction of 4-nitrobenzenethiol (4NBT), which transforms it into p, p'-dimercaptoazobenzene (DMAB), is detected by using an in situ SERS technique at the excited wavelength of 785 nm. According to the temperature and laser power density dependent photocatalytic reaction rates observed on the Ag NP arrays, we quantitatively determined that the reductive coupling of 4NBT is more likely to occur as the gap decreases. The finite-difference time-domain (FDTD) simulation results demonstrate that the plasmonic hot spots are significantly enhanced with a decrease in gap, which in turn reduces activation energy.
