Relationship between subjective socioeconomic status and sense of gain of health-care reform and the mediating role of self-rated health: A cross- sectional study in China
Authors: Su Yuan , LI Yueping 
Published: November 2021

Abstract
Background: The sense of gain has gradually become the main evaluation index for the effectiveness of China’s deepening reform and is affected by many factors. However, there is no relevant research on the sense of gain of health-care reform (SGHR) and its influencing factors. The purpose of this study was to explore the influence of subjective socioeconomic status (SSS) on SGHR and the mediating role of self-rated health (SRH) between them.Methods: Data (27,437 samples total) from China Family Panel Studies (CFPS) in 2018 were included in the analysis. A nonparametric test was used to explore the differences in demographic characteristics of SGHR, and a correlation analysis and mediating effect model were used to explore the influence of SSS on SGHR and the mediating effect of SRH.Results: Demographic characteristics such as age, urban and rural areas, educational background, marriage and choice of medical treatment had significant differences in the distribution of perceived acquisition of medical reform. SSS, SHR and SGHR are positively correlated with each other. SSS not only directly affects SGHR positively but also indirectly affects SGHR through SRH.Conclusions: SSS is an important predictor of SGHR, and SHR plays a partially mediating role in SGHR.
Evaporation in Hydrological Models Under Rising CO2: A Jump into The Unknown
Authors: Lemaitre-Basset Thibault , OUDIN Ludovic , THIREL Guillaume 
Published: November 2021

Abstract
Many hydrological models use the concept of potential evaporation (PE) to simulate actual evaporation. PE formulations often neglect the effect of carbon dioxide (CO2), which challenges their relevance in a context of climate change and rapid changes in CO2 atmospheric concentrations. In this work, we implement three options from the literature to take into account the effect of CO2 on stomatal resistance in the well-known Penman–Monteith PE formulation. We assess their impact on future runoff using the Budyko framework over France. On the basis of an ensemble of Euro-Cordex climate projections using the RCP 4.5 and RCP 8.5 scenarios, we show that taking into account CO2 in PE formulations largely reduces PE values but also limits projections of runoff decrease, especially under an emissive scenario, namely, the RCP 8.5. Whereas the classic Penman–Monteith formulation yields decreasing runoff projections over most of France, taking into account CO2 yields more contrasting results. Runoff increase becomes likely in the north of France, which is an energy-limited area, with different levels of runoff response produced by the three tested formulations. The results highlight the sensitivity of hydrological projections to the processes represented in the PE formulation.

Abstract
Objective: To evaluate the real-world effectiveness and gene predictive analysis of olaparib in Chinese patients with metastatic castration-resistant prostate cancer (mCRPC) .Methods: A multicenter, retrospective, real-world study was conducted by involving Chinese patients with mCRPC from December 2017 to June 2021. Homologous Recombination repair (HRR)gene mutation (HRRm) status was identified using targeted next-generation sequencing (NGS). The primary endpoint includes prostate-specific antigen (PSA) response rate (PSA50). Secondary end points include PSA progression-free survival (PSA-PFS), exploratory endpoints include PSA50, and PSA-PFS in HRRm-negative patients with variants of unknown significance (VUS). Survival rates were analyzed using Kaplan–Meier (KM) plot.Results: A total of 39 eligible patients with a median age of 65 (interquartile range [IQR]: 59.5-69.5) years were included in the study. Overall, 40% (12/30) of the patients with mCRPC achieved PSA50 and the median PSA-PFS was 3.1 months (95% Confidence interval [CI]: 2.4-7). Furthermore, higher PSA50 rate and longer PSA-PFS were observed in HRRm-positive patients (PSA50: 50% [7/14]; median PSA-PFS: 5.3 months, 95% CI: 3.73–10). Among the HRRm-positive patients, those harboring the BRCA2 aberrations experienced best clinical efficacy (PSA50: 55.5% [5/9] and median PSA-PFS [95% CI]: 9.5 months [4.3, NA]). Clinical benefit was also observed in HRRm-negative patients (PSA50: 31.3% [5/16]; median PSA-PFS [95% CI]:2.05 months [1.5,8]), wherein most patients with a PSA50 response were carrying VUS mutations (PSA50: 50% [4/8]; median PSA-PFS [95% CI]: 2.75 months [1.27, NA]). In one patients with mutation in the ATR gene, the PSA level decreased by 62%. Conclusion: Olaparib improved PSA response and prolonged PSA-PFS in Chinese mCRPC patients especially in those carrying HRR mutation. Among the HRR genes, patients with BRCA2 mutation showed the best clinical benefit. Besides, some patients carrying HRR VUS alternations and other DNA damage response (DDR) gene mutations also showed response to olaparib treatment, indicating that the clinical benefits observed in HRR negative group were driven by VUS and other DDR gene mutation. However, this should be further explored in the future, and more molecular functional studies are needed to reclassify VUS mutations for better clinical treatment decision-making and management of mCRPC.

Published: November 2021

Abstract
The initial defects have greatly affected the gear transmission under harsh working conditions in the fields of wind power and ships. The influence of linear initial defects on the evolution of wear characteristics of helical gears was studied. The laser marking device was used to process the linear initial defect along the tooth width direction, and the gear without initial defect was used for comparison. It can be concluded that the linear initial defect changed the meshing state of the gear tooth, and greatly shortened the normal wear life of the gear, the normal wear life of the gear is shortened by about 45%, and the wear rate in the stable wear stage is increased by about 56%, a great deal of pitting corrosion and plastic flow on the tooth surface occurred in the pitch circle position of the defective gear. In addition, the lubrication condition deteriorated in the later period caused by lubricating oil pollution and the hard particles falling off the gearbox bearings entered the meshing surface and the emerged crack, which further accelerated the wear process of gear.
The Potential Mechanisms of AMOC Multidecadal Periods in CMIP6/CMIP5 Preindustrial Simulations
Authors: Ma Xiaofan , Huang Gang , Li Xichen , Li Shouwei 
Published: November 2021

Abstract
Observations, theoretical analyses, and climate models show that the period of multidecadal variability of the Atlantic Meridional Overturning Circulation (AMOC) is related to westward temperature propagations in the subpolar North Atlantic, which is modulated by oceanic baroclinic Rossby waves. Here, we find major periods of AMOC variability of 12-28 years and associated westward temperature propagations in the preindustrial simulations of 9 CMIP6/CMIP5 models. Comparison with observations shows that the models reasonably simulate ocean stratifications in turn oceanic Rossby waves in the subpolar North Atlantic. The timescales of Rossby waves propagating on a static background flow across the subpolar North Atlantic basin overestimate the AMOC periods. The mean flow effects involving westward geostrophic self-advection and eastward mean advection largely shorten and greatly improve the estimate of AMOC periods through increasing Rossby wave speeds. Our results illustrate the importance of considering mean flow effects on Rossby wave propagations in the estimate of AMOC periods.

Abstract
C57BL/6NTac (B6NTac) and C57BL/6NRj (B6NRj) mice were fed a high calorie diet and treated with liraglutide. 42 mice would have been needed in an ordinary one-way ANOVA to show a reduction in glycosylated hemoglobin (HbA1c) in B6NTac mice, but incorporating the sequenced fecal microbiota in a two-way ANOVA reduced the group size needed to obtain a statistical significance to 12 mice. In B6NRj mice there was no impact of liraglutide on HbA1c neither with or without microbiota incorporation. In both sub-strains, the liraglutide effect on glucose tolerance and body weight was powered by incorporation of microbiota clusters. Although B6NTac mice were genetically far more conform than the B6NRj mice, incorporation of a genetic characterization by short tandem repeats had only little impact on the outcome of data evaluation. In conclusion, incorporation of microbiota characterisation powers data evaluation in diet induced obesity mouse strains, which are influenced by the microbiota.

Abstract
BackgroundEthiopia’s National Malaria Control and Elimination Program aims to diagnose all suspected malaria cases within 24 hours of fever onset and provide prompt treatment for confirmed cases. This study explored psychosocial factors associated with no-, delayed- and prompt- care-seeking among female caregivers of children under five with fever in rural Ethiopia.MethodsHousehold surveys were conducted from 2016–2019 among female caregivers (N = 2453) of children under five years old in Oromia; Amhara; Southern Nations, Nationalities, and Peoples Region (SNNPR); and Tigray. Prompt and delayed care-seeking were defined as seeking treatment within ≤ 24 hours or > 24 hours of symptom onset respectively. Contextual factors explored included sociodemographic factors, household supply of bed nets, exposure to health messages, and household vulnerability (a measure of financial access to food, shelter, schooling, and medical treatment). Ideational factors included psychosocial factors related to care-seeking (knowledge, self-efficacy, response efficacy, beliefs, involvement in decision-making, and household social support).ResultsThe prevalence of fever among children under five was 18% (ranging from 9% in Tigray to 34% in SNNPR. Overall, 45% of caregivers of children with fever sought care promptly, while 23% delayed care-seeking and 32% sought no care. Prompt care-seeking rates were higher among caregivers with positive attitudes toward prompt care-seeking (48%), involved in decision-making (48%) or perceived equitable gender norms in the community (65%). Caregivers with a high care-seeking ideation had increased odds of prompt care-seeking (aOR: 2.65; 95% CI: 1.74–4.02). Significant contextual factors included residence in the Oromia region (aOR: 2.99; 95% CI:1.40–6.41), caregivers age 35–49 years (aOR: 0.49; 95% CI: 0.26–0.95), residence in vulnerable households (aOR: 2.01; 95% CI: 1.28–3.18).ConclusionsAmong this rural Ethiopian population, prompt care-seeking was low but positively influenced by both ideational and contextual psychosocial factors occurring at the caregiver level. Multi-sectoral interventions at the individual, community, and health facility levels are needed to improve prompt care-seeking. These include social behavior change interventions to improve ideation, complemented by health facility interventions to ensure provision of high-quality services and structural interventions to increase educational attainment in these rural settings.
Association of Maternal Mood Symptoms in Pregnancy with Exclusive Breastfeeding at Six Weeks Postpartum: A Cross-Sectional Study
Authors: Lai Xin , Peng Songxu , Yao Zhenzhen , Meng Liping 
Published: November 2021

Abstract
Background: Previous studies have shown that postpartum depression negatively affects breastfeeding practices. However, it is not clear whether maternal mood symptoms during pregnancy affect exclusive breastfeeding (EBF) behavior. Our study aimed to quantify the relationship between maternal mood symptoms (depression/anxiety) during pregnancy and EBF.Methods: A cross-sectional study was conducted at Baoan Maternal and Child Health Hospital, Shenzhen, China, from January 1, 2016, to December 31, 2016, among women who had delivered in the hospital and completed the 6-week postpartum visit. A structured questionnaire was designed to collect information on maternal mood symptoms during pregnancy and EBF status at 6 weeks postpartum. Logistic regression models were used to evaluate the associations between maternal mood symptoms (depression/anxiety) during pregnancy and EBF at 6 weeks postpartum.Results: In total, 6324 women were included in this study. In univariate analysis, we observed that depression during pregnancy was associated with a reduced risk for EBF (OR = 0.66; 95% CI: 0.54-0.81; P < 0.001). In the fully adjusted model, depression during pregnancy was still significantly associated with a reduced risk of EBF (OR=0.69; 95% CI: 0.56–0.86; P < 0.001). However, there was no significant difference in the rate of EBF between the anxiety and non-anxiety groups of women (OR=0.88; 95% CI: 0.77–1.01; P > 0.05). Conclusion: We believe that our findings confirm the adverse impact of maternal depression during pregnancy on EBF behavior. Therefore, to improve conditions for breastfeeding of infants, additional attention should be paid to women with depressive symptoms during pregnancy.

Published: November 2021

Abstract
This study aimed to assess the isokinetic strength performance of the knee and shoulder in amateur boxer, and further to explore the contribution of knee and shoulder peak torque to different punches. Boxers (6 females and 8 males) were measured the dynamic concentric torque of knee flexion(F) and extension(E), shoulder external rotation (ER) and internal rotation (IR) at 60°/S, 180°/S. We tested the punching force of three techniques by Kistler Instruments. At 60°/S, F/E ratios of the dominant (D) knee of female boxers were lower than those of non-dominant (ND) side (p=0.03). At two angular velocities, all boxers demonstrated higher ER/IR ratios in ND (p=0.011 for males, p=0.025 for females). Bilateral difference of knee flexor in females was greater (p=0.038) than that in males. The maximum correlation was found at 180°/S between punching forces and the joints strength. ANOVA analyses revealed that athletes with greater punching force tend to have higher knee strength. Although correlations between shoulders strength and punching forces were strong, they did not discriminate between athletes who punched with higher punching force. In order to effectively transfer muscle strength to punching force, rapid completion of action should be highlighted in strength training, especially lower-limb strength.
Convolutional Neural Network and Clustering-Based Codebook Design Method for Massive MIMO Systems
Authors: Xing Jing , Hu Die 
Published: November 2021

Abstract
In this paper, we propose a convolutional neural network(CNN) and clustering based codebook design method. Specifically, we train two different CNN networks, i.e., CNN1 and CNN2, to compress the channel state information(CSI) matrices into the channel vectors and recover the channel vectors back into the CSI matrices, respectively. After that, the clustering algorithm clusters the output of CNN1, i.e., the channel vectors into several clusters and outputs a centroid for each cluster. The sum-distance between each centroid and the channel vectors in the corresponding cluster is the smallest, which can lead to the maximum sum-rate of massive MIMO codebook design. Then, the centroids are recovered into matrices by CNN2. The output of CNN2 is our proposed codebook for massive multiple-input multiple-output(MIMO) systems. In the simulation, we compare the performance of different clustering algorithms. We also compare the proposed codebook with the traditional Discrete Fourier Transform(DFT) codebook. Simulation results show the superiority of the proposed algorithm.

Abstract
Background Clinical handover is a vital communication process for patient safety; transferring patient responsibility between healthcare professionals (HCPs). Exploring handover processes in maternity care is fundamental for service quality, addressing continuity of care and maternal mortality.MethodsThis mixed-methods study was conducted in all three maternity hospitals in Banjul, The Gambia. Shift-to-shift maternity handovers were observed and compared against a standard investigating content and environment. Semi-structured interviews and focus group discussions with doctors, midwives and nurses explored handover experience.Results110 nurse/midwife shift-to-shift handovers were observed across all shift times and maternity wards; only 666 of 845 women (79%) were handed over. Doctors had no scheduled handover. Shift-leads alone gave/received handover, delayed [median 35 minutes, IQR 24-45] 82% of the time; 96% of handovers were not confidential and 29% were disrupted. Standardised guidelines and training were lacking.A median 6 of 28 topics [IQR 5-9] were communicated per woman. Information varied significantly by time, high-risk classification and location. For women in labour, 10 [IQR 8-14] items were handed-over, 8 [IQR 5-11] for women classed ‘high-risk’, 5 [IQR 4-7] for ante/postnatal women (p<0.001); >50% had no care management plan communicated.21 interviews and two focus groups were conducted. Facilitators and barriers to effective handover surrounding three health service factors emerged; health systems, organisation culture and individual clinician factors.ConclusionMaternity handover was inconsistent, hindered by contextual barriers including lack of team communication and guidelines, delays, with some women omitted entirely. Findings alongside HCPs views demonstrate feasible opportunities for enhancing handover, thereby improving women's safety.
Influence of Clay Mineral Content on the Mechanical Properties and Microfabrics of Tailings

Published: November 2021

Abstract
Clay mineral content has an important influence on the mechanical behavior of tailings, and the mechanical behavior of tailings directly affects the stability of tailings dams. XRF and XRD tests were carried out on tailings from three different regions. The chemical and mineral compositions of the tailings are analyzed. The strength and failure deformation of tailings were studied by carrying out laboratory triaxial compression tests. The effect of clay content on the stress path of tailings was investigated. The microfabric of tailings samples was examined with scanning electron microscopy (SEM) and nitrogen adsorption tests. The results show that the confining pressure corresponding to the samples exhibiting strain hardening increases with increasing clay mineral content in the tailings. The cohesion of tailings increases linearly, and the specific surface area decreases as the content of clay minerals increases. Nitrogen adsorption test results reveal from a microscopic point of view that changes in pore structure are associated with the content of clay minerals. The higher the content of clay minerals is, the higher the proportion of micropores (aggregated interior). Macroscopically, the overall porosity decreases and the fineness of the pores increases with clay content, which will directly affect the mechanical properties of tailings.
Research on the Association Between Perceived Neighborhood Environment and Life Satisfaction Among Older Adults in Shanghai, China: Do Social Capital And Gender Matter?
Authors: Lu Nan , Wu Bei 
Published: November 2021

Abstract
This study examined the mediator role of social capital on the association between perceived neighborhood environment and life satisfaction among older adults in urban China, and further tested the moderating effect of gender in the above paths (i.e., from neighborhood environment to life satisfaction; from neighborhood environment to social capital; from social capital to life satisfaction). We used quota sampling approach to recruit 472 respondents aged 60 years old or older in Shanghai in 2020. From the perspective of structural equation modeling, multiple group analysis was conducted to examine the proposed hypotheses. The measurement model of social capital was well established in urban Chinese community contexts. Based on the whole sample, the results of the mediation model showed that social capital played a mediation role in the association between neighborhood environment and life satisfaction. Furthermore, the results of multiple group analysis showed that the association between neighborhood environment and cognitive social capital was only significant among older women. The findings highlight the role of neighborhood environment and social capital in building age-friendly communities.
Association Between Early Initiation of Breastfeeding and Reduced Risk of Respiratory Infection: Implications for Non-separation of Infant and Mother in the COVID-19 Context

Published: November 2021

Abstract
Early initiation of breastfeeding, within one hour of birth, is vital for the health of newborns, and reduces morbidity and mortality. Secondary analysis of the 2016 Nepal Demographic and Health Survey (DHS) showed that early initiation of breastfeeding significantly reduced the risk of acute respiratory infection (ARI) in children under two years. Early initiation of breastfeeding requires maternal proximity. However, during the COVID-19 pandemic, guidance varied, with some recommending that infants and mothers with SARS-CoV-2 be isolated from one another. Nepal’s Ministry of Health and Population recommended non-separation, but the adherence to this guidance was inconsistent. Separation of infant and mother inhibits early initiation of breastfeeding and increases the risk that infants will suffer from ARIs. Maternal proximity, non-separation and early initiation of breastfeeding should be promoted in all birthing facilities.
