A Heterogeneous Network Modeling Method Based on Public Goods Game Theory to Explore Cooperative Behavior in VANETs

Cooperative vehicular networking has been widely studied in recent years. Existing evolution game theoretic approaches to study cooperative behavior in Vehicular Ad hoc Network (VANET) are mainly based on the assumption that VANET is constructed as a homogeneous network. This modeling method only extracts part attributes of vehicles and does not distinguish the differences between strategy and attribute. In this paper, we focus on the heterogeneous network model based on the public goods game theory for VANET. Then we propose a Dynamic Altruism Public Goods Game (DAPGG) model consisting of rational nodes, altruistic nodes, and zealots to more realistically characterize the real VANET. Rational nodes only care about their own benefits, altruistic nodes comprehensively consider the payoffs in the neighborhood, while zealots insist on behaving cooperatively. Finally, we explore the impacts of these attributes on the evolution of cooperation under different network conditions. The simulation results show that only adding altruistic nodes can effectively improve the proportion of cooperators, but it may cause conflicts between individual benefits and neighborhood benefits. Altruistic nodes together with zealots can better improve the proportion of cooperators, even if the network conditions are not suitable for the spread of cooperative behavior.
Impact of Stigma on People Living with Chronic Hepatitis B

Background People with chronic infectious diseases such as hepatitis B can face stigma, which can influence everyday life as well as willingness to engage with medical professionals or disclose disease status. A systematic literature review was performed to characterize the level and type of stigma experienced by people infected with hepatitis B virus (HBV) as well as to identify instruments used to measure it. Methods A literature review was performed using the PubMed, Embase and Cochrane Library databases to identify studies describing HBV-related stigma. For inclusion, articles were required to be published in full-text form, in English and report quantitative or qualitative data on HBV-related stigma that could be extracted. Results A total of 23 (17 quantitative and 6 qualitative) articles examined HBV-related stigma. The scope of the review was global but nearly all identified studies were conducted in countries in the WHO Southeast Asia or Western Pacific regions or within immigrant communities in North America. Several quantitative studies utilized tools specifically designed to assess aspects of stigma. Qualitative studies were primarily conducted via patient interviews. Internalized and social stigma were common among people living with chronic HBV . Some people also perceived structural/institutional stigma, with up to 20% believing that they may be denied healthcare and up to 30% stating they may experience workplace discrimination due to HBV. Conclusion HBV-related stigma is common, particularly in some countries in Southeast Asia and the Western Pacific region and among Asian immigrant communities, but is poorly characterized in non-Asian populations. Initiatives are needed to document and combat stigma (particularly in settings/jurisdictions where it is poorly described) as well as its clinical and socioeconomic consequences.
Nutritional Challenges in Pregnant Women with Renal Diseases: Relevance to Fetal Outcomes

Pregnancy in women affected by chronic kidney disease (CKD) has become more common in recent years, probably as a consequence of increased CKD prevalence and improvements in the care provided to these patients. Management of this condition requires careful attention since many clinical aspects have to be taken into consideration, including the reciprocal influence of the renal disease and pregnancy, the need for adjustment of the medical treatments and the high risk of maternal and obstetric complications. Nutrition assessment and management is a crucial step in this process, since nutritional status may affect both maternal and fetal health, with potential effects also on the future development of adult diseases in the offspring. Nevertheless, few data are available on the nutritional management of pregnant women with CKD and the main clinical indications are based on small case series or are extrapolated from the general recommendations for non-pregnant CKD patients. In this review, we discuss the main issues regarding the nutritional management of pregnant women with renal diseases, including CKD patients on conservative treatment, patients on dialysis and kidney transplant patients, focusing on their relevance on fetal outcomes and considering the peculiarities of this population and the approaches that could be implemented into clinical practice.
High-intensity Focused Ultrasound Treatment in Moderate Glaucoma Patients: Results of a 2-Year Prospective Clinical Trial

Supplemental Digital Content is available in the text. Precis: Ultrasound Cyclo Plasty (UCP) treatment using high-intensity focused ultrasound (HIFU) is an effective and safe therapy to reduce intraocular pressure (IOP) in moderate glaucoma patients as was measured during a 2-year follow-up period. Purpose: The purpose of this study was to evaluate the long-term safety and efficacy of the UCP procedure using HIFU in moderate glaucoma patients. Patients and Methods: A prospective interventional noncomparative study was carried out. Fifteen patients (15 eyes) with moderate open-angle glaucoma were enrolled. All eyes were treated with UCP-HIFU. A thorough ophthalmic examination and IOP measurements were performed before the UCP-HIFU procedure and at 1 day, 1 week, 4 weeks, 3 months, 6 months, 1 year, and 2 years after the procedure. The primary outcome was defined as a surgical success (IOP reduction of 20% or ≥5 mm Hg) at the last follow-up visit. The secondary outcomes were the mean IOP at each follow-up visit, number of medications used, complications profile, and reinterventions. Results: The mean preoperative IOP at baseline was 26.8±5.0 mm Hg. All patients had a positive response and a lower IOP after treatment, with a relatively stable 31% reduction in IOP during the follow-up period. A significant reduction in IOP was observed at all postprocedure examination points (P<0.01), with a mean 17.6±4.4 mm Hg at 2 years after the procedure (P=0.005). Surgical success was achieved in 87% of the patients at their last follow-up visit. There was a nonsignificant decrease in the mean number of glaucoma medications from 2.5±0.8 to 2.0±1.0 at 2 years (P=0.48). No major intraoperative or postoperative complications were noted. Conclusion: UCP-HIFU treatment is an effective, safe, and well-tolerated method to reduce IOP in patients with moderate glaucoma.
Genome-wide DNA methylation analysis in canine gastrointestinal lymphoma

DNA methylation is the covalent modification of methyl groups to DNA mostly at CpG dinucleotides and one of the most studied epigenetic mechanisms that leads to gene expression variability without affecting the DNA sequence. Genome-wide analysis of DNA methylation identified the signatures that could define subtypes of human lymphoma patients. The objective of this study was to conduct the genome-wide analysis of DNA methylation in dogs with gastrointestinal lymphoma (GIL). Genomic DNA was extracted from endoscopic biopsies from 10 dogs with GIL. We performed Digital Restriction Enzyme Assay of DNA Methylation (DREAM) for genome-wide DNA methylation analysis that could provide highly quantitative information on DNA methylation levels of CpG sites across the dog genome. We successfully obtained data of quantitative DNA methylation level for 148,601–162,364 CpG sites per GIL sample. Next, we analyzed 83,132 CpG sites to dissect the differences in DNA methylation between GIL and normal peripheral blood mononuclear cells (PBMCs). We found 383–3,054 CpG sites that were hypermethylated in GIL cases compared to PBMCs. Interestingly, 773 CpG sites including promoter regions of 61 genes were identified to be commonly hypermethylated in more than half of the cases, suggesting conserved DNA methylation patterns that are abnormal in GIL. This study revealed that there was a large number of hypermethylated sites that are common in most of canine GIL. These abnormal DNA methylation could be involved in tumorigenesis of the canine GIL.
Differential clinicopathologic features of EGPA-associated neuropathy with and without ANCA

Objective To investigate the clinicopathologic features of eosinophilic granulomatosis with polyangiitis (EGPA)–associated neuropathy with a focus on the presence or absence of anti-neutrophil cytoplasmic antibodies (ANCAs). Methods We examined the clinical features and pathologic findings of sural nerve biopsy specimens from 82 patients with EGPA-associated neuropathy. Of these patients, 32.9% were myeloperoxidase (MPO)-ANCA positive, and 67.1% were MPO-ANCA negative. PR3-ANCA was negative in all of 78 examined patients. Results Upper limb symptoms were more frequently reported as initial neuropathic manifestations in the MPO-ANCA–positive group than in the MPO-ANCA–negative group (44.4% vs 14.6%, p < 0.01). The serum levels of C-reactive protein were significantly higher in the MPO-ANCA–positive group than in the MPO-ANCA–negative group (p < 0.05). Sural nerve biopsy specimens showed findings suggestive of vasculitis (i.e., destruction of vascular structures) in epineurial vessels; these results were seen more frequently in the MPO-ANCA–positive group than in the MPO-ANCA–negative group (p < 0.0001). Conversely, the numbers of eosinophils in the lumen of the epineurial vessels (p < 0.01) and epineurial vessels occluded by intraluminal eosinophils (p < 0.05) were higher in the MPO-ANCA–negative group than in the MPO-ANCA–positive group. Furthermore, the incidence of eosinophil infiltration in the endoneurium was higher in the MPO-ANCA–negative group than in the MPO-ANCA–positive group (p < 0.01). Conclusions This study suggests that the pathogenesis of EGPA comprises at least 2 distinct mechanisms: ANCA-associated vasculitis resulting in ischemic effects and inflammation, which is prominent in MPO-ANCA–positive patients, and eosinophil-associated vascular occlusion leading to ischemia and eosinophil-associated tissue damage, which is conspicuous in MPO-ANCA–negative patients.
Genetic manipulation of LKB1 elicits lethal metastatic prostate cancer

This study unravels an unprecedented murine model of lethal metastatic prostate cancer, based on the combined deletion of Pten and Lkb1. Importantly, minimal activity of LKB1 is sufficient to hamper prostate cancer cell aggressiveness, thus redefining the relationship between gene dosage and tumor suppression.
Ethnobotanical knowledge and practices of traditional healers in Harar, Haramaya, Bati and Garamuleta, Eastern Ethiopia

The study was conducted to reveal and document ethnobotanical knowledge and practices of traditional healers in selected sites of Eastern Hararghie. Ethnobotanical data were collected using semi-structured interviews and field observation from 9 traditional healers in 4 study sites of Eastern Hararghie. Data were collected, quantified and summarized using graphs, tables and different ranking techniques. The study revealed 32 medicinal plants species belonging to 31 genera and 25 families. The plants were used to treat 17 major human and animal ailments, 81% used for the treatment of human disorders while the remaining 19% for both. Of the reported species 44% were herbs, and 28 % each were shrubs and trees. Leaf was the most frequently used plant part accounting 62%, followed by fruit (16%) and root (16%). Oral administration was the most commonly used route (60%), followed by topical (31%) route. The most preferred solvent added during the preparation of medicinal plants was water (50%), while 38% of the plant remedies used without any solvent. Fidelity value analysis indicated that Allium sativum L. (83.3%), Gomphocarpus integer N.E. Br (80%), Punica granatum L. (75%) and Cordia africana L. (75%) were the most preferred species used for the treatment of abdominal pain, febrile illness, evil spirit and skin lesions, respectively. Moreover, Allium sativum L. was the first ranked medicinal plant used for the treatment of abdominal pain followed by Vernonia amygdalina Del. and Cucurbita pepo L. This study suggested that traditional healers in eastern Hararghie zone have profound ethnobotanical knowledge and practices.

2019 Year in Review: Patient-Ventilator Synchrony

Patient-ventilator synchrony is a popular topic of research on mechanical ventilation. This review puts this research into both contemporary and historical perspective. Five areas of research are described: literature reviews, manual detection of synchrony problems, automated detection of synchrony problems, modes for improving synchrony, and effects of sedation. Patient-ventilator synchrony is a popular topic of research on mechanical ventilation. This review puts this research into both contemporary and historical perspective. Five areas of research are described: literature reviews, manual detection of synchrony problems, automated detection of synchrony problems, modes for improving synchrony, and effects of sedation. We note that this type of research lacks a standardized vocabulary and associated taxonomy, which generates difficulty in communication among students and researchers, as well as in comparison of results. Hence, we conclude this paper with some suggestions for improvement in that regard.
Wheat individual grain-size variance originates from crop development and from specific genetic determinism

Wheat grain yield is usually decomposed in the yield components: number of spikes / m2, number of grains / spike, number of grains / m2 and thousand kernel weight (TKW). These are correlated one with another due to yield component compensation. Under optimal conditions, the number of grains per m2 has been identified as the main determinant of yield. However, with increasing occurrences of post-flowering abiotic stress associated with climate change, TKW may become severely limiting and hence a target for breeding. TKW is usually studied at the plot scale as it represents the average mass of a grain. However, this view disregards the large intra-genotypic variance of individual grain mass and its effect on TKW. The aim of this study is to investigate the determinism of the variance of individual grain size. We measured yield components and individual grain size variances of two large genetic wheat panels grown in two environments. We also carried out a genome-wide association study using a dense SNPs array. We show that the variance of individual grain size partly originates from the pre-flowering components of grain yield; in particular it is driven by canopy structure via its negative correlation with the number of spikes per m2. But the variance of final grain size also has a specific genetic basis. The genome-wide analysis revealed the existence of QTL with strong effects on the variance of individual grain size, independently from the other yield components. Finally, our results reveal some interesting drivers for manipulating individual grain size variance either through canopy structure or through specific chromosomal regions.
Cervicovaginal microbiome and natural history of HPV in a longitudinal study

Background Human papillomavirus (HPV) infection is one of the most common sexually transmitted infections. However, only a small percentage of high-risk (HR) HPV infections progress to cervical precancer and cancer. In this study, we investigated the role of the cervicovaginal microbiome (CVM) in the natural history of HR-HPV. Methods This study was nested within the placebo arm of the Costa Rica HPV Vaccine Trial that included women aged 18–25 years of age. Cervical samples from two visits of women with an incident HR-HPV infection (n = 273 women) were used to evaluate the prospective role of the CVM on the natural history of HR-HPV. We focus specifically on infection clearance, persistence, and progression to cervical intraepithelial neoplasia grade 2 and 3 (CIN2+). The CVM was characterized by amplification and sequencing the bacterial 16S V4 rRNA gene region and the fungal ITS1 region using an Illumina MiSeq platform. OTU clustering was performed using QIIME2. Functional groups were imputed using PICRUSt and statistical analyses were performed using R. Results At Visit 1 (V1) abundance of Lactobacillus iners was associated with clearance of incident HR-HPV infections (Linear Discriminant Analysis (LDA)>4.0), whereas V1 Gardnerella was the dominant biomarker for HR-HPV progression (LDA>4.0). At visit 2 (V2), increased microbial Shannon diversity was significantly associated with progression to CIN2+ (p = 0.027). Multivariate mediation analysis revealed that the positive association of V1 Gardnerella with CIN2+ progression was due to the increased cervicovaginal diversity at V2 (p = 0.040). A full multivariate model of key components of the CVM showed significant protective effects via V1 genus Lactobacillus, OR = 0.41 (0.22–0.79), V1 fungal diversity, OR = 0.90 (0.82–1.00) and V1 functional Cell Motility pathway, OR = 0.75 (0.62–0.92), whereas V2 bacterial diversity, OR = 1.19 (1.03–1.38) was shown to be predictive of progression to CIN2+. Conclusion This study demonstrates that features of the cervicovaginal microbiome are associated with HR-HPV progression in a prospective longitudinal cohort. The analyses indicated that the association of Gardnerella and progression to CIN2+ may actually be mediated by subsequent elevation of microbial diversity. Identified features of the microbiome associated with HR-HPV progression may be targets for therapeutic manipulation to prevent CIN2+. Trial registration ClinicalTrials.gov NCT00128661.
Preoperative Neutrophil-to-Lymphocyte Ratio Was a Predictor of Overall Survival in Small Renal Cell Carcinoma: An Analysis of 384 Consecutive Patients

Objective The aim of this study was to investigate the prognostic significance of the preoperative neutrophil-to-lymphocyte ratio (NLR) in small renal cell carcinoma (sRCC, ≤4 cm). Methods This study was approved by the review board (NO.XYFY2019-KL032-01). Between 2007 and 2016, a total of 384 consecutive patients who underwent curative surgery for sRCC at our institution were evaluated. Patients were divided into high NLR and low NLR groups by plotting the NLR receiver operating characteristic curve. The Kaplan–Meier method was utilized to graphically display survivor functions. Univariate and multivariate Cox proportional hazards regression analysis addressed time to overall survival (OS) and cancer-specific survival (CSS). Results Of the 384 patients, 264 (68.8%) were males and 120 (31.2%) were females. Median follow-up time after surgical resection was 54 months. One hundred and eighty-seven (48.7%) patients had a high NLR (≥1.97), and the remaining 197 (51.3%) had a low NLR (<1.97). Patients with high NLR were more likely to be aged compared with patients with low NLR (P=0.028). High NLR was associated with decreased OS and CSS compared with low NLR (P=0.028). High NLR was associated with decreased OS and CSS compared with low NLR (P=0.028). High NLR was associated with decreased OS and CSS compared with low NLR (P=0.028). High NLR was associated with decreased OS and CSS compared with low NLR ( Conclusions Elevated preoperative NLR is an independent adverse prognostic factor for OS after surgery with curative intent for sRCC.
Internalization of miPEP165a into Arabidopsis Roots Depends on both Passive Diffusion and Endocytosis-Associated Processes

MiPEPs are short natural peptides encoded by microRNAs in plants. Exogenous application of miPEPs increases the expression of their corresponding miRNA and, consequently, induces consistent phenotypical changes. Therefore, miPEPs carry huge potential in agronomy as gene regulators that do not require genome manipulation. However, to this end, it is necessary to know their mode of action, including where they act and how they enter the plants. Here, after analyzing the effect of Arabidopsis thaliana miPEP165a on root and aerial part development, we followed the internalization of fluorescent-labelled miPEP165a into roots and compared its uptake into endocytosis-altered mutants to that observed in wild-type plants treated or not with endocytosis inhibitors. The results show that entry of miPEP165a involves both a passive diffusion at the root apex and endocytosis-associated internalization in the differentiation and mature zones. Moreover, miPEP165a is unable to enter the central cylinder and does not migrate from the roots to the aerial part of the plant, suggesting that miPEPs have no systemic effect.
