A photothermal nanoconfinement reactor (PNCR) system is proposed and demonstrated by using hollow carbon nanospheres (HCNs) to enhance the performance of the chemical reaction. Under light irradiation, the local temperature of the HCN inner void space was much higher than the bulk solution temperature because the confined space concentrates heat and inhibits heat loss. Using the temperature-sensitive model reaction, peroxydisulfate (PDS) activation to oxidize micropollutant, it is shown that the degradation rate of sulfamethoxazole in the PNCR system is 7.1 times of that without nanoconfinement. It is further discovered that the high-quality local heat inside the nanoconfined space shifted the model reaction from an otherwise non-radical pathway to a radical-based pathway. This work provides an interesting strategy to produce a locally high temperature, which has a wide range of applications to energy and environmental fields.
This study aimed to explore the correlation between patient power distance and their willingness to participate in patient safety.
The positive significance of patient participation in patient safety has been widely recognized worldwide, but in clinical practice, patients' willingness to participate is uneven and lack of initiative.
This study is a cross-sectional survey of hospitalized patients (n = 660) from six tertiary hospitals in Shanghai. Pearson's correlation analysis analyzed data.
Patients have a higher power distance (4.08 ± 0.59). The willingness of patients to participate in patient safety was moderate (3.50 ± 1.03). Pearson's correlation analysis shows that patients' power distance negatively and slightly affected their willingness of participation (r = -.134, p < .001). The perceived authority dimension of patients' power distance has no significant correlation with patients' willingness of participation (p > .05). The emotional communication dimension of patients' power distance negatively affects patients' disease-related willingness (r = -.077, p < .001). The decision-making participation dimension of patients' power distance negatively affects patients' willingness (R = -.201, p < .001).
Medical staff should focus on patients' power distance in medical activities. In addition, appropriate communication methods should be selected according to patients' power distance, so as to help them improve their willingness of participation.
Nurse managers should educate nurses on the knowledge of power distance and its importance. By evaluating patients' power distance, humanistic care and meticulous communication are implemented to encourage patients to actively participate in patient safety.

The objective of this study was to examine levels of cytokines across normal term pregnancy in an Indian population. Additionally we have also explored for possible associations between inflammatory markers and fetal growth parameters.
A multiplex panel of 24 analytes was used to examine levels of inflammatory markers in maternal serum at three time points during pregnancy and in cord blood from women with no reported comorbidities who delivered a singleton live baby at term (N = 23), enrolled in the GARBH-Ini pregnancy cohort. Linear mixed models were applied to construct longitudinal cytokine trajectories with gestational age. Pearson correlation was used to calculate intra-visit correlation between cytokines. Principal component analysis (PCA) was performed to examine cytokine combinations prevalent across pregnancy, and their association with fetal growth parameters was determined by multivariable regression.
Significant increase in sFLT-1, Flt3L, PLGF, IL-4, and IL-18 and a decrease in VCAM-1 concecomes. Growth factors showed maximum longitudinal variation with gestational age and strong correlations were identified between various cytokines at all time points across pregnancy.
This study aimed to develop a theoretical model of caring leadership in nursing.
Nurse leader's role plays an integral part in complex health care institutions. As a common feature of leaders, leaders' caring leadership can positively influence the stakeholders in health care institutions. Still, little is known about caring leadership in nursing, especially in the Chinese cultural background.
Grounded theory was used to develop the theoretical model of caring leadership. Both semi-structured interviews and open-ended questionnaire surveys were used to collect data for constructing the theory model. Ten nurse leaders and 11 nurse staff were recruited for an interview, and 168 nurse leaders and 286 nurses were recruited for an open-ended questionnaire survey.
A theoretical model of caring leadership was developed using five core attributions benevolent to others, appreciate the uniqueness, facilitate self-actualization, maintain mutual benefit and motivate with charisma. Caring leadership in nurse lead a new perspective and understanding of caring and leadership for nurse leaders. Nurse leaders need to strengthen their responsibilities and personal qualities while caring for nurse staff to improve leadership efficacy based on the theoretical model. And caring leadership can help nurse leaders to balance the interests of stakeholders, leading to positive consequences for nurse staff, patients and health care organisations.
The aim of this study was to examine the perspectives of experienced Australian remote area nurses about remote nursing staff retention strategies.
There is low retention of remote area nurses in remote Australia. Retention of remote area nurses can be improved by a supportive environment including good management, professional development and supervision.
This is a qualitative study using in-depth interviews with seven registered nurses with a minimum of 3 years remote area nursing experience. Participants were interviewed by phone, with the interviews audio-recorded then transcribed and analysed thematically.
Participants had on average 12 years of experience as a remote area nurse. Ceftaroline manufacturer They valued teamwork, effective and flexible management practices and the ability to maintain their own cultural and social connectedness. A flexible service model with regular short breaks, filled by returning agency nurses to enable continuity of care and cultural connections, was seen as a viable approach.
Flexible management practices that encourage short breaks for remote area nurses may increase retention. This would need to occur within a supportive management framework.
Management strategies that reduce isolation from personal and social networks can increase the retention of skilled remote area nurses.

We used adult Wistar rats (16 males; 32 females), divided into groups that were fed either a standard (diet S) or a high-energy (diet F). After 90 days of obesity induction, the rats were submitted to obtain female offspring from parents S and F. The offspring stayed with their mothers until 21 days of age (weaning day). Our previous studies have proved the programming effects of parental obesity on the skeletal system of their offspring at the age of 21 days. Weaned female offspring were divided into groups S/S-parents and offspring fed the S diet; S/F-parents fed the S diet and offspring fed the F diet; F/S-parents fed the diet F and offspring with the diet S; F/F-parents and offspring fed the F diet (F/F). After sacrifice, isolated femurs were assessed by peripheral quantitative computed tomography and by a three-point bending test. The bones were examined at 49 and 90 days of life. We found that nutritional programming has a significant influence on the development and metabolism of the skeletal system in females during growth and maturity. Moreover, the modification of nutrition alters the metabolism of bone tissue, and the osteotropic effects vary depending on the nature of the change, as well as the stage of development. Reducing the caloric content of the diet inhibits the mineralization and decreases the mechanical strength of the bones while increasing the caloric content of the diet has a beneficial osteotropic effect.In this study, açaí-loaded kefir microbial films obtained in solutions containing demerara sugar, a low-cost and relatively organic sugar, were prepared. Environmental scanning electron microscopy (ESEM), atomic force microscopy (AFM), stereometric and multifractal analyses were applied to study the influence of the concentration of açaí over the surface morphology as well as its multifractal nature. The ESEM and AFM images showed that low concentrations of acai berry form surface covered by bacteria, while higher concentrations promote yeast growth. The autocorrelation function suggested that the degree of surface anisotropy changes as the concentration of açaí increases, while the Minkowski Functionals confirmed that the sample with the highest content has a different morphology than the samples containing 10-40 ml. The multifractal analysis revealed that the surfaces have a strong multifractal behavior, where the multifractal singularity strength was higher in the sample containing the highest concentration of açaí. The sample with the highest concentration was then mapped to have a greater vertical growth of its spatial patterns. These results prove that image analysis using mathematical tools can be very useful for the characterization of biological-based systems for application in the biomedicine field. We characterized the micromorphology of the 3D surface of the kefir biofilms associated with Acai extract. The 3D surface analysis of the samples was performed using by environmental scanning electron microscope and atomic force microscopy. We determined the multifractal and Minkowski Functionals of the analyzed samples.
Widespread structural alterations have been shown to be implicated in individuals with generalized anxiety disorder (GAD). However, there have been inconsistent findings in cortical volume (CV) differences. Most structural neuroimaging studies looking at GAD used region-based approach with relatively small sample sizes, let alone be specific to adolescents with GAD. We believe this is the first study to look at CV measures using a network-based approach in a larger sample of adolescents with GAD. The goal of the current study was to focus on three different brain networks (i.e., Limbic, Frontoparietal, and Default Mode Network [DMN]) in adolescents with GAD.
The study involved 81 adolescents with GAD and 112 typically developing (TD) comparison individuals matched on age (15.98 and 15.63 respective means), sex (42F/39M and 45F/67M), and IQ (101.90 and 103.94 respective means). Participants underwent structural MRI. Freesurfer was used to estimate CV (both network-specific and region-specific within networks) and region-specific sub-cortical volume measures.
