Effect of Peer Mentoring on Quality of Life among CKD Patients: Randomized Controlled Trial

Introduction: CKD is associated with decreased quality of life (QOL). Peer mentoring (PM) leads to improved QOL in various chronic diseases. The effectiveness of PM on QOL of patients with CKD has not been previously studied. We conducted a randomized clinical trial to test the effectiveness of face-to-face (FTF) and online mentoring by trained peers, compared with usual care, on CKD patients’ QOL. Methods: We randomized 155 patients in one of 3 groups: (1) FTF PM (n = 52), (2) online PM (n = 52), and (3) textbook only (n = 51). Peer mentors were patients with CKD, who received formal training through 16 h of instruction. Participants in all 3 groups received a copy of an informational textbook about CKD. Participants assigned to PM received either 6 months of FTF or online PM. The outcomes included time-related changes in domain scores of the Kidney Disease Quality of Life (KDQOL)-36 for each of the groups over the 18-month study period. Results: Compared with baseline, online PM led to improved scores in domains of the KDQOL-36 at 18 months: Effects of Kidney Disease (p = 0.01), Burden of Kidney Disease (p = 0.01), Symptoms and Problems of Kidney Disease (p = 0.006), SF-12 Physical Composite Summary (p = 0.001), and SF-12 Mental Composite Summary (p < 0.001). There were no statistically significant changes from baseline in domain scores of KDQOL-36 within the FTF PM and textbook-only groups. Conclusions: Among patients with CKD, online PM led to increased scores in domains of the KDQOL-36 at 18 months. The study was limited to English-speaking subjects with computer literacy and internet access.
Maxillary Sinus Floor Augmentation with Autogenous Bone Graft Compared with a Composite Grafting Material or Bone Substitute Alone: a Systematic Review and Meta-Analysis Assessing Volumetric Stability of the Grafting Material

ABSTRACT Objectives Test the hypothesis of no difference in the volumetric stability of the grafting material following maxillary sinus floor augmentation with autogenous bone graft compared with composite grafting material or bone substitute alone applying the lateral window technique. Material and Methods MEDLINE (PubMed), Embase, Cochrane library and hand-search of relevant journals were conducted. Human studies published in English until the 9th of October 2020 were included. Outcome measures included three-dimensional volumetric changes of the grafting material and potential predictive parameters. Volumetric changes were evaluated by descriptive statistics and meta-analysis including 95% confidence interval. Results Electronic search and hand-searching resulted in 102 entries. Four randomized controlled trials with unclear risk of bias fulfilled the inclusion criteria. The volumetric stability of the grafting material was significantly improved by mixing autogenous bone graft with a non-resorbable xenograft compared with autogenous bone graft. Meta-analyses assessing absolute and relative volumetric changes demonstrated no significant differences between autogenous bone graft compared with allogeneic bone graft, synthetic biomaterials combined with autogenous bone graft or used alone. Association between volumetric changes of the grafting material and potential predictive parameters were not assessed in the included studies. Conclusions Volumetric reduction of the augmented area seems inevitable following maxillary sinus floor augmentation regardless of the grafting material. The volumetric stability of autogenous bone graft is improved with addition of xenograft compared with autogenous bone graft. However, conclusions drawn from this systematic review should be interpreted with caution since only four studies using three-dimensional radiographic measurements were included.
Postgraduate students’ perspective on supporting “learning from home” to solve the COVID-19 pandemic

It is very important to study this topic because it is a novel education process applied in the postgraduate program in Muhammadiyah University of Prof. DR. HAMKA. The objective of this present research was to reveal how the postgraduate student perceive of or respond to the online learning process. A mixed method between qualitative and quantitative ones was adopted in this present research. The research results showed that most students who had experienced of the online learning activities encountered some obstacles because they had never conducted “LFH (Learning from Home) activities before. The respondents were 428 postgraduate students who actively joined in the “LFH” activities. From the students, 316 students used the platform zoom as the supporting application in the LFH activities. The respondents filled in the Google Form, then the collected data could be quickly and accurately processed. Other respondents preferred the google classroom, the whatsapp and other applications in following the learning activities according to the agreement and features provided in each flat form. There were 408 respondents stating that there was a two-way communication between the lecturers and the students during the LFH activities. They stated that the limited Internet network hindered the online lecturing. Thirty one respondents declared that technology limitations hampered the online lecturing, and 105 students revealed that it is the limitations in using the application that caused the online lecturing to become obstacles. We believe that understanding the scope of e-learning can provide a positive color to the world of education by opening all time and space boundaries so that everyone can get a decent education.
GO_3D_OBS: the multi-parameter benchmark geomodel for seismic imaging method assessment and next-generation 3D survey design (version 1.0)

Abstract. Detailed reconstruction of deep crustal targets by seismic methods remains a long-standing challenge. One key to address this challenge is the joint development of new seismic acquisition systems and leading-edge processing techniques. In marine environments, controlled-source seismic surveys at a regional scale are typically carried out with sparse arrays of ocean bottom seismometers (OBSs), which provide incomplete and down-sampled subsurface illumination. To assess and minimize the acquisition footprint in high-resolution imaging process such as full waveform inversion, realistic crustal-scale benchmark models are clearly required. The deficiency of such models prompts us to build one and release it freely to the geophysical community. Here, we introduce GO_3D_OBS – a 3D high-resolution geomodel representing a subduction zone, inspired by the geology of the Nankai Trough. The 175 km × 100 km × 30 km model integrates complex geological structures with a viscoelastic isotropic parameterization. It is defined in the form of a uniform Cartesian grid containing ∼ 33.6e9 degrees of freedom for a grid interval of 25 m. The size of the model raises significant high-performance computing challenges to tackle large-scale forward propagation simulations and related inverse problems. We describe the workflow designed to implement all the model ingredients including 2D structural segments, their projection into the third dimension, stochastic components, and physical parameterization. Various wavefield simulations that we present clearly reflect in the seismograms the structural complexity of the model and the footprint of different physical approximations. This benchmark model is intended to help to optimize the design of next-generation 3D academic surveys – in particular, but not only, long-offset OBS experiments – to mitigate the acquisition footprint during high-resolution imaging of the deep crust.
Interactions among hydro-aeolian processes and micro-geomorphology stimulate hot spots of sediment carbon source and sink within a coppice dune system

ABSTRACT We evaluated the impacts of the interactions among hydro-aeolian processes and micro-geomorphology on mechanisms controlling the sediment carbon source and sink within a coppice dune. The sediment sampling process was performed within different positions of each dune. Sediment grain size distribution, geometric mean diameter, mean weight diameter, labile SOC, CO2 flux, and C mineralization ratio were measured. The finest sediments were observed on the dune edge. The labile SOC and CO2 flux rate showed an increasing trend in the edge, windward, and top positions. However, the C mineralization ratio decreased only in the dune edge. A significant increase of clay fractions at the dune edge can result from the horizontal sediment transport by runoff from the interdune area to the dune. The SOC could bond with clay fractions to contribute toward the formation of soil aggregation, causing less vulnerability of SOC to microbial respiration. A significant increase of sand fractions, transported by the aeolian process, on the top and windward positions could not protect SOC against decomposition. The interactions among hydro-aeolian processes and micro-geomorphology could encourage the hot spots of sediment carbon reservoirs within the dryland landforms that have a significant proportion in the exchange of carbon to the atmosphere.
THE PREVALENCE OF BODY DYSMORPHIC DISORDER WITH A TENDENCY TO ANOREXIA NERVOSA IN ADOLESCENTS

Background: Anorexia nervosa (AN) and body dysmorphic disorder (BDD) are severe body image disorders that severely interfere with the daily functioning of the individual. They are separate but overlapping nosologically entities. There is a study on the tendency of wrong eating behaviour in adolescents with specifications for anorexia nervosa in Jakarta 11.6% and there is also a study at High School in Jakarta 88.5% of adolescents experience wrong eating behaviour with the specifications of anorexia nervosa. And the two largest epidemiological surveys regarding BDD, there were 2.5% women and 2.2% men. With a fairly high number of these two events, this has the potential to have a negative impact on someone’s health. This study aims to discuss the impact of anorexia nervosa. Methods: The researcher used several literature and scientific journals, which was based on 15 journals and literature, discussing a tendency to anorexia nervosa with the incidence of Body Dysmorphic Disorder and its medical emergencies. Conclusion: There is a correlation of anorexia nervosa among teenager especially girl teenage
Recurrent events modelling of haemophilia bleeding events

A pharmacokinetic–pharmacodynamic (PK‐PD) approach is developed for modelling the recurrent bleeding events in patients with severe haemophilia to investigate the relationship between factor VIII plasma activity level and the instantaneous risk of a bleed. The model incorporates patient‐level pharmacokinetic (PK) information obtained through measurements taken prior to the study which are used to fit a non‐linear mixed‐effects two‐compartment PK model. Dosing times within the study are combined with the PK model to provide the estimated factor VIII plasma level for all patients, which is used as a time‐dependent covariate within the recurrent events model. Methods are developed to correct the attenuation in covariate effects that would otherwise arise due to the discrepancy between estimated and true factor VIII. In contrast to existing methods proposed for such data, such as count data regression or time‐to‐event analysis, the new method allows all the bleeding times to be used to investigate the relationship between current factor VIII and risk of a bleed. The performance of the proposed estimators are assessed via simulation and found to outperform the naive estimator, which treats the estimated factor VIII levels as if they were measured without error, both in terms of bias and mean squared error.
Capital structure and monitoring by local owners

ABSTRACT We examine how owners’ portfolio diversification influences their firms’ financial decision-making and performance. We find that firms with high local ownership use less leverage, but firms with local ownership by locally biased owners use higher debt levels relative to firms with diversified local owners. Firms with high local ownership in urban regions use higher debt levels. In rural regions, firms with high locally biased ownership use higher debt levels relative to firms with diversified local ownership. Finally, although we find weak evidence that firms with high local ownership underperform the market, the underperformance is smaller in firms with high locally biased ownership. Thus, locally biased owners, not local owners with diversified portfolios, have an informed monitoring role in firms, and this effect seems to mitigate negative liquidity consequences. The separation of local owners into those with locally biased and those with diversified portfolios determines when and how local ownership can be used as a good proxy for informed investors.
Prevalence and risk factors associated with subclinical mastitis in lactating dairy cows under smallholder dairy farming in North East Tanzania

A cross-sectional survey was carried out between October 2016 and May 2017 to determine the prevalence of subclinical mastitis (SCM), associated bacterial pathogens and risk factors under smallholdersmall holder dairy farms in North East Tanzania. The study involved 195 cross breed dairy cows from 130 dairy farms. Data were collected based on questionnaire interview, direct observation, screening using California Mastitis Test (CMT) and culture of bacteria. The overall prevalence of SCM based on California Mastitis Test (CMT) was 70.8 and 66.4% and bacteria isolation recorded at 56.4 and 38.4% at cow and quarter levels, respectively. Prevalence defined by CMT was significantly (p<0.0001) associated with wet-dirty bedding material (OR=11.61) and poor udder (OR =6.67). Increased culture-positivity at quarter level was significantly associated with CMT-positive cows (OR= 20.59), teat injuries (OR=23.56), wooden floor (OR=2.02) and poor udder hygiene (OR =2.16). Stripping method of hand milking and first and second parity were significantly associated with lower prevalence of CMT-positive cows and culture positive quarters (p<0.05). Major bacteria species isolated included Staphylococcus aureus (55.4%), Staphylococcus epidermidis (10.8%), Escherichia coli (7.9%) and Streptococcus agalactiae (5.9%). This study demonstrated SCM is a major health constraint of dairy cattle in North Eastern Tanzania. Key words: Prevalence, Subclinical -mastitis, California Mastitis Test, bacteria, risk factors.
Modelling the Interactions of Soils, Climate, and Management for Grass Production in England and Wales

This study examines the effectiveness of a model called LINGRA-N-Plus to simulate the interaction of climate, soil and management on the green leaf and total dry matter yields of ryegrass in England and Wales. The LINGRA-N-Plus model includes modifications of the LINGRA-N model such as temperature- and moisture-dependent soil nitrogen mineralization and differential partitioning to leaves and stems with thermal time from the last harvest. The resulting model was calibrated against the green leaf and total grass yields from a harvest interval x nitrogen application experiment described by Wilman et al. (1976). When the LINGRA-N-Plus model was validated against total grass yields from nitrogen experiments at ten sites described by Morrison et al. (1980), its modelling efficiency improved greatly compared to the original LINGRA-N. High predicted yields, at zero nitrogen application, were related to soils with a high initial nitrogen content. The lowest predicted yields occurred at sites with low rainfall and shallow rooting depth; mitigating the effect of drought at such sites increased yields by up to 4 t ha−1. The results highlight the usefulness of grass models, such as LINGRA-N-Plus, to explore the combined effects of climate, soil, and management, like nitrogen application, and harvest intervals on grass productivity.
The Influence of Bedding-Plane Orientation on the Degradation Characteristics of a South African Waterberg Coal

ABSTRACT A tomographic study of coal microstructure (coal bedding planes, pre-existing cracks, microlithotype boundaries, and mineral boundaries) was undertaken to explain its influence on coal degradation due to impact. A number of samples were cut from a large block of Waterberg run-of-mine coal. It was characterized using microfocus x-ray computed tomography before and after undergoing impact breakage in a single particle drop shatter test. The tomograms generated before and after impact were compared and the breakage characteristics determined. It was found that the internal structure of the coal samples influenced the breakage of coal, with new cracks initiating, terminating, or propagating along pre-existing cracks, microlithotype-, and mineral grain boundaries. The contribution of the physical structures to the breakage characteristics could not be predicted for individual particles, but the overall effect on a population of particles was fitted using a Rosin-Rammler distribution. The orientation of the bedding planes in relation to the impact surface also influenced the propagation of cracks through the samples. Newly formed cracks propagated deeper into a particle if the impact force was applied along the bedding planes.
Related-Party Transactions and Audit Fees

This research aims to analyze the association between the related-party transactions and audit fees. This study used 781 observations listed on the Indonesia Stock Exchange from 2010 to 2017. The analysis technique used in this research was the Ordinary Least Square Regression analysis model processed with STATA 14.0 software. This study found that related-party transactions are positively and significantly related to audit fees. The result indicated that the related-party transactions increase audit fees paid by companies. It also investigated the moderating effect of industry specialty auditors. This indicated that auditor specialization strengthened the relationship between the related-party transactions and audit fees. The market share proxy was used to measure industry specialization. However, this proxy still has disadvantages as it can generate different market shares. This study found that related-party transactions increased audit fees. The results of this study can be used as consideration in making decisions for related parties. Article History Received: 8 September 2020 Revised: 31 Oktober 2020 Accepted: 7 November 2020
The formation and characteristics of ZnO/AlN and ZnO/AlN/ZnO core-shell nanowires

ABSTRACT In this work, we fabricate the p-type ZnO/AlN/ZnO core-shell nanowire arrays on Al2O3 substrate. The SEM images show the core-shell structure and the connection phenomenon appeared during the deposition process. The XRD results show a better crystal quality after annealing. The sample exhibits some unique properties after annealing treatment. Including the improvement of crystal quality and the shift of the PL emission peak. The low temperture PL spectra show a neutral acceptor bound exciton (A0X) emission (at 3.355 eV), and the emission at 3.325 eV is ascribe to the free electron to the acceptor transition (FA). The calculated result is found in good coincidence with the experiment.
The Effects of a Structural Reform on Corporate Outcomes in China: A Generalized Propensity Score Matching Approach

ABSTRACT In March 2010, the China Securities Regulatory Commission (CSRC) launched a reform introducing both margin trading and short selling into China’s stock market. This paper examines the impact of this reform on corporate outcomes in the short run and long run. In our analysis, we adopt a generalized propensity score (GPS) matching method that allows treatment effects to change over time. Our empirical results not only indicate that the reform positively bolstered stock trading activities, but also constrained managers’ behavior, such as their method of earnings management. We think that disclosure policies adopted by managers can influence stock trading activities. This study has several important implications that policymakers might find useful. We provide evidence supporting the CSRC to allow more firms to join the reform.
Study of blood levels of Lactate, Vitamin D and Nucleated Red Blood Cells for early prediction of Hypoxic–Ischemic Encephalopathy: A case-control study

Objective and background: Perinatal asphyxia is a serious medical condition in which there is lack of oxygen or blood flow during, or even after the labor process. So, this study aimed to study serum blood levels of Lactate, vitamin D and count of nucleated Red Blood Cells (nRBCs) per 100 White Blood Cells (WBCs) as early biological predictors of Hypoxic–Ischemic Encephalopathy (HIE) after birth Asphyxia.Methods: A retrospective case-control study was conducted on 20 neonates with HIE comprising the cases (APGAR ≤ 5) and another 20 neonates representing the control group with their age, sex, and weight matched, admitted to NICU from March 2020 to the end of September 2020 at Menoufia University Hospital and El-Bagour Central Hospital, Egypt. Venous blood samples for lactate, vitamin D and nucleated RBCs were drawn during 1st 6h of birth and sent for analysis. Sarnat score was used to assess the severity of HIE.Results: Venous blood levels of lactate and nucleated Red Blood Cells per 100 White Blood Cells (nRBC/100 WBC) counts were significantly higher in HIE neonates than in the control group with a highly significant difference (P-value < 0.001). While serum Vitamin D was significantly lower in the HIE group than in the control (P-value < 0.001). Conclusion: Serum lactate level, vitamin D level and nRBCs/100 WBCs might be used as biomarkers in the early prediction of HIE.
The Association of TNF-α Promoter Polymorphisms with Genetic Susceptibility to Cervical Cancer in a Chinese Han Population

Background The tumour necrosis factor-α (TNF-α) gene plays an important role in the host immune response, which will influence the development and clearance of cancer. Polymorphism of the TNF-α promoter region is considered to influence its transcription and be a risk factor for tumorigenesis. In the current study, we evaluated the role of TNF-α promoter region polymorphisms in susceptibility to cervical intraepithelial neoplasia (CIN) and cervical cancer (CC). Methods A total of 2732 subjects, including 1173 healthy controls, 579 patients with CIN and 980 patients with CC in a Chinese Han population, were selected for the current study. Five SNPs in the TNF-α promoter, rs1799964 (−1031 C>T), rs1800630 (−863 A>C), rs1799724 (−857 C>T), rs1800629 (−308 A>G) and rs361525 (−238 A>G), were selected and genotyped using TaqMan Assays. The association of these SNPs with CIN and cervical cancer was evaluated among healthy controls, CIN and CC patients. Results The frequency distribution of rs1800629 and rs361525 alleles was significantly different between the CC group and the control group (P=0.009 and P=0.002). The rs1800629 A allele was found to be a protective factor for CC (OR=0.72; 95% CI=0.56–0.92). The rs361525 A allele was found to be a risk factor for CC (OR=1.69; 95% CI=1.21–2.38). After pathological subtyping of CC, the allele distribution of rs1800629 and rs361525 were both significantly different between the cervical squamous cell carcinoma and control groups (P=0.002 and P<0.001). The rs1800629 A allele was protective factor for cervical squamous cell carcinoma (OR=0.66; 95% CI=0.50–0.86). The rs361525 A allele was a risk factor for cervical squamous cell carcinoma (OR=1.87; 95% CI=1.32–2.65). Moreover, the genotypic frequency of rs361525 was significantly different between cervical cancer stage I and stage II (P=0.003). Conclusion The rs1800629 and rs361525 in the TNF-α promoter are associated with susceptibility to CC in the Chinese Han population.
