Javan slow loris (Nycticebus javanicus) one of the species of the genus Nycticebus is endemic in Java. Their distribution region is in West Java and Banten, and also reported to be found in Central Java and East Java, although very rarely. Status of the species is Critically Endangered due to high levels of poaching, habitat loss and habitat fragmentation, so that the necessary conservation in order to increase the population. For conservation management it is necessary to know the status of genetic resources that play of role in breeding, then this research is to explore the genetic population of the Javan slow loris from some locations in West Java. The research objective was to assess the diversity of their current population of Java loris through the control region (D-loop) of mitochondrial DNA (mtDNA). A total of 23 individuals samples from Gunung Halimun Park, Tasikmalaya, Garut, Ciamis, Jember and confiscated at the Rehabilitation Center IAR Bogor were used in this stydy. Specific primers of D-loop are used for loris with a length of 296 bp sequence. The result showed there are only five different sites and formed six haplotypes, each haplotypes only 1-3 nucleotides different. Low genetic diversity is shown as much as 42.96% of individuals show the same sequence or genetic distance (d) = 0 that indicate was monomorf population from different population. The genetic distance of the entire population was 0.003 ± 0:01 (0.3%).

This study was conducted to examine the comparison the quality of spermatozoa in four genetic groups of poultry (Pelung chicken, Nunukan chicken, Sentul chicken, and Bangkok chicken). The parameters of this study were the concentration of spermatozoa, motility, viability, semen volume, color, and consistency. The study was designed using a Completely Randomized Design (CRD) with four local chicken nations and four replications. The results showed that the volume of Nunukan chicken semen was 0.32±0.01 mL/ejaculation, Bangkok chicken was 0.31±0.01 mL/ejaculate, Sentul chicken was 0.15±0.02 mL/ejaculate and Pelung chicken was 0.23±0.02 mL/ejaculation. the color of fresh semen is white (Pelung chicken, Nunukan chicken and Sentul chicken) except chicken Bangkok has the color of cream semen. Pelung chicken has a concentration of spermatozoa 5,043.33±51 million/mL, Nunukan chicken 3,250.22 ±45 million/mL, Sentul chicken 3,002.87±67 million/mL, and Bangkok chicken 3,002.87 ± 67 million/mL. Motility of Pelung chicken 84.,69 ± 1.12%, Bangkok chicken 82.35±1.85%, Nunukan chicken 77.74±1.57% and Sentul chicken 77.64±1.65%. Viability spermatozoa of Sentul chicken was 90.35 ± 1.21%, Bangkok chicken was 90.64 ± 1.16%, Pelung chicken was 89.17 ± 1.23% and Nunukan chicken was 86.29 ± 1.15%. It can be concluded that the motility spermatozoa of Pelung chicken and Bangkok chicken is better than the spermatozoa motility of Nunukan chicken and Sentul chicken. The viability of Sentul chicken and Bangkok chicken was higher compared to the viability semen of chicken Pelung and chicken Nunukan.

Abstract
Background
Molecular breeding has opened new avenues for crop improvement with the potential for faster progress. As oil palm is the major producer of vegetable oil in the world, its improvement, such as developing compact planting materials and altering its oil’s fatty acid composition for wider application, is important.

Results
This study sought to identify the QTLs associated with fatty acid composition and vegetative traits for compactness in the crop. It integrated two separate interspecific backcross two (BC2) mapping populations to improve the genetic resolution and evaluate the consistency of the QTLs identified. A total of 1,963 markers (1,814 SNPs and 149 SSRs) spanning a total map length of 1793 cM were integrated into a consensus map. For the first time QTLs associated with vegetative parameters were identified in an interspecific hybrid population, and carotene content apart from these associated with fatty acid composition. The QTL analysis observed 9, 4 and 8 genomic loci associated significantly with fatty acids, carotene content and compactness, respectively.

Conclusions
Major genomic region influencing the parameters associated with compactness and fatty acid composition was identified across separate populations using two different methods for QTL detection. Other significant locus influencing compactness, carotene content and FAC were identified either being common to both populations or specific to a particular genetic background. It is hoped that the QTLs identified will be useful tools for marker-assisted selection and accelerate the process of identifying desirable genotypes for breeding.

Abstract
Background: During an epidemic event, emergency care settings are fraught with urgency, uncertainty and changes to the clinical scenario and practice. Such situations challenge the capability of emergency nurses to perform their duties in a well-planned and systematic manner. To date, little is known about the coping strategies adopted by emergency nurses during an epidemic event. The present study explored the behaviours and strategies developed by emergency nurses to handle uncertainty and practice changes during an epidemic event.Methodology and methods: A qualitative design based on the Straussian grounded theory approach was established. A total of 26 emergency nurses from Hong Kong were recruited by purposive and theoretical sampling strategies. Semi-structured, face-to-face, individual interviews were conducted for data collection. The data were transcribed verbatim and analysed using grounded theory coding procedures. The Consolidated Criteria for Reporting Qualitative Research guidelines were followed.Results: Adapting protocol to the evolving context of practice was revealed as the core category. Four interplaying sub-categories were identified: (1) completing a comprehensive assessment, (2) continuing education for emerging infectious disease management, (3) incorporating guideline updates and (4) navigating new duties and competencies. The nurses demonstrated the prudence to orientate themselves to an ambiguous work situation and displayed the ability to adapt and embrace changes in their practice and duties.Conclusions: These findings explain how emergency nurses must adapt and adjust their practice and behaviours to the evolving nature of an epidemic event. These findings also offer insights on the need for education and training schemes that allow emergency nurses to acquire and develop the necessary decision-making and problem-solving skills to handle a public health emergency.﻿

Published: January 2020

Abstract
Background : Pulmonary hypertension is definitively diagnosed by the measurement of mean pulmonary artery (PA) pressure (mPAP) using right heart catheterization. Cardiovascular magnetic resonance (CMR) four-dimensional (4D) flow analysis can estimate mPAP from blood flow vortex duration in the PA, with excellent results. Moreover, the peak systolic tricuspid regurgitation (TR) pressure gradient (TRPG) measured by Doppler echocardiography is commonly used in clinical routine to estimate systolic PA pressure. This study aimed to compare CMR and echocardiography with regards to quantitative and categorical agreement, and diagnostic yield for detecting increased PA pressure. Methods : Consecutive clinically referred patients (n=60, median [interquartile range] age 60 [48–68] years, 33% female) underwent echocardiography and CMR at 1.5T (n=43) or 3T (n=17). PA vortex duration was used to estimate mPAP using a commercially available time-resolved multiple 2D slice phase contrast three-directional velocity encoded sequence covering the main PA. Transthoracic Doppler echocardiography was performed to measure TR and derive TRPG. Diagnostic yield was defined as the fraction of cases in which CMR or echocardiography detected an increased PA pressure, defined as vortex duration ≥15% of the cardiac cycle (mPAP ≥25 mmHg) or TR velocity >2.8 m/s (TRPG >31 mmHg). Results : Both CMR and echocardiography showed normal PA pressure in 39/60 (65%) patients and increased PA pressure in 9/60 (15%) patients, overall agreement in 48/60 (80%) patients, kappa 0.49 (95% confidence interval 0.27-0.71). CMR had a higher diagnostic yield for detecting increased PA pressure compared to echocardiography (21/60 (35%) vs 9/60 (15%), p<0.001). In cases with both an observable PA vortex and measurable TR velocity (34/60, 56%), TRPG was correlated with mPAP (R 2 =0.65, p<0.001). Conclusions : There is good quantitative and fair categorical agreement between estimated mPAP from CMR and TRPG from echocardiography. CMR has higher diagnostic yield for detecting increased PA pressure compared to echocardiography, potentially due to a lower sensitivity of echocardiography in detecting increased PA pressure compared to CMR, related to limitations in the ability to adequately visualize and measure the TR jet by echocardiography. Future comparison between echocardiography, CMR and invasive measurements are justified to definitively confirm these findings.

Abstract
Background: HIV-exposed infant diagnosis (EID) and initiation of HIV-positive infants on anti-retroviral therapy (ART) requires a well-coordinated cascade of care. Loss-to-follow-up (LTFU) can occur at multiple steps and effective EID is impeded by human resource constraints, difficulty with patient tracking, and long waiting periods. The objective of this research was to conduct formative research to guide the development of an intervention to improve the pediatric HIV care cascade in central Mozambique. The study was conducted in Manica and Sofala Provinces where the adult HIV burden is higher than the national average. The research focused on 3 large clinics in each province, along the highly populated Beira corridor. Methods: The research was initiated in 2014 over 3 months at six facilities and consisted of 1) patient flow mapping and collection of health systems data from postpartum, child-at-risk, and ART service registries, 2) measurement of clinic waiting times, and 3) patient and health worker focus groups. Results: HIV testing and ART initiation coverage for mothers tends to be high, but EID and pediatric ART initiation are hampered by lack of patient tracking, long waiting times, and inadequate counseling to navigate the care cascade. About 76% of HIV-positive infants were LTFU and did not initiate ART. Conclusions: Effective interventions to reduce LTFU in EID and improve pediatric ART initiation should focus on patient tracking, active follow-up of defaulting patients, reduction in EID turn-around times for PCR results, and initiation of ART by nurses in child-at-risk services.

Abstract
Background. Our aim was to determine the relationship between the use of fluoroquinolones and the risk of aortic diseases.Methods. PubMed, EMBASE and the Web of Science were searched from inception to July 6, 2019, to identify observational studies that evaluated the risk of aortic diseases associated in users of fluoroquinolones compared with nonusers or users of other antibiotics. The primary outcome was the first occurrence of aortic diseases. We used the GRADE approach to rate the strength of evidence. We used the inverse variance method random-effect model to estimate the odds ratios (ORs) with 95% CIs, and statistical heterogeneity was assessed by the I2 statistic.Results. This meta-analysis enrolled 2,829,385 patients reported the relationship between fluoroquinolones and the risk of aortic diseases. Compared with nonusers or users of other antibiotics, users of fluoroquinolone had a significantly increased risk of aortic diseases (adjusted OR, 2.10; 95% CI, 1.65-2.68; P=.000, I2=16.4%). The quality of evidence was moderate, and the number needed to harm (NNH) for aortic diseases among patients was estimated to be 1301.Conclusions. The fluoroquinolone use in patients significantly increases the risk of new-onset aortic diseases. Clinicians need to pay attention to these severe adverse events when considering fluoroquinolone use.

Abstract
Auxin plays an important role in regulating plant development. To aquire feasible regulation effects and mechanism of IAA on drought tolerance in white clover, relative water content, chlorophyll content, several major phytohormone level, the expression of gene-related to IAA signal perception and synthesis, as well as drought-resistance related transcription factor genes and senescence genes were investigated in white clover plants under 15% polyethylene glycol-6000 (PEG-6000) after 1µM exogenous IAA pre-treatment and 100µM L-AOPP (inhibitor of IAA synthesis) pre-treatment. Compared to control, drought stress significantly diminished stem dry weight (g/10 plants), relative water content (RWC, %) and total chlorophyll content (Chl, mg/g). Exogenous IAA significantly increased RWC and Chl, however, L-AOPP, drastically decreased stem dry weight (g/10 plants), RWC and Chl compared with direct drought treatment. Besides that, compared with direct drought treatment, exogenous IAA significantly improved ABA content and JA content, up-regulated expression level of auxin-responsing genes (GH3.1, GH3.9, IAA8), drought-resistance related transcription factor genes (bZIP11, DREB2, MYB14, MYB48, WRKY2, WRKY56, WRKY108715) and drought resistance gene (RD22), meanwhile, down-regulated expression level of auxin-responsing genes (GH3.3, GH3.6, IAA27) and leaf senescence genes (SAG101 and SAG102). L-AOPP, contrarily, compared with direct drought treatment, significantly reduced ABA, GA3 and JA content, down-regulated expression level of GH3.1, GH3.9, IAA8, bZIP11, DREB2, MYB14, MYB48, WRKY2, WRKY56, WRKY108715, ERD and RD22, meanwhile, up-regulated SAG101 and SAG102. Collectively, these data suggested a positive role of exogenous IAA in alleviating drought stress damage in white clover.

Abstract
Background: To investigate the influence of hyperhomocysteinemia (HHcy) and metabolic syndrome (MetS) on left ventricular hypertrophy (LVH) in residents in rural Northeast China. Methods: We performed a cross-sectional baseline data analysis of 6837 subjects (mean age: 54±10 years) recruited from a rural area of China. Anthropometric indicators were measured according to standard methods. MetS was defined by the modified ATP III criteria. HHcy was defined according to the WHO standard: an Hcy level >15 μmol/L representing HHcy. Four groups were defined: non-HHcy & non-MetS, HHcy & non-MetS, MetS & non-HHcy and HHcy & MetS.Results: The left ventricular mass index for height2.7 (LVMH2.7) in both sexes was significantly higher in the HHcy & MetS group than in the non-HHcy & non-MetS group (females: 51.23±16.34 vs. 40.09±10.55 gm-2.7, P<0.001; males: 48.67±12.24 gm-2.7 vs. 42.42±11.38 gm-2.7, P<0.001). A similar result was observed in those groups when using the left ventricular mass index (LVMI) for body surface area to define LVH (females: 103.58±31.92 gm-2 vs. 86.63±20.47 gm-2, P<0.001; males: 106.10±24.69 gm-2 vs. 98.16±23.29 gm-2, P<0.001). The results of multiple regression analysis indicated that the HHcy & MetS group had a higher risk of LVH than the other three groups (OR: 1.628 for LVMI, P<0.001, OR: 2.433 for LVMH2.7, P<0.001). Moreover, subjects in the HHcy & non-MetS group [OR (95% CI): 1.297 (1.058, 1.591) for LVMI, P<0.05; OR (95% CI): 1.248 (1.044, 1.492) for LVMH2.7, P<0.05] also had a statistically greater risk of LVH than subjects in the non-HHcy & non-MetS group. The HHcy & non-MetS group was also found to be significantly and independently associated with LVH.Conclusion: Hyperhomocysteinemia has an independent effect on LVH. The combined effect of MetS and hyperhomocysteinemia might increase the strength of the abovementioned effects.

Abstract
Background: In addition to an overall rise in vancomycin-resistant Enterococcus faecium (VREfm), an increase in certain strain types marked by sequence type (ST) and cluster type (CT) has been reported in Germany over the past few years. Outbreak analyses at Charité - Universitätsmedizin Berlin revealed the frequent occurrence of VREfm ST117 CT71 isolates in 2017 and 2018. To investigate whether ST117 CT71 have emerged in recent years or whether these strains have been circulating for a longer time, we retrospectively analyzed non-outbreak strains that occurred between 2008 and 2018 to identify frequent STs and CTs.Methods: In total, 120 VREfm isolates obtained from clinical and surveillance cultures from the years 2008, 2013, 2015, and 2018 were analyzed. Thirty isolates per year comprising the first 7 - 8 non-outbreak isolates of each quarter of the respective year were sequenced using whole genome sequencing. MLST and cgMLST were determined as well as resistance genes and virulence factors. Risk factors for VREfm ST117 were analyzed in a multivariable analysis with patient characteristics as possible confounders. Results: The percentage of VREfm of type ST117 increased from 17% in 2008 to 57% in 2018 (p=0.012). In 2008, vanA genotype accounted for 80% of all ST117 isolates compared to 6% in 2018. VanB CT71 first appeared in 2018 and predominated over all other ST117 at 43% (p<0.0001). The set of resistance genes (msrC, efmA, ermB, dfrG, aac(6')-Ii, gyrA, parC and pbp5) and virulence factors (acm, esp, hylEfm, ecbA and sgrA) in CT71 was also found in other ST117 non-CT71 strains, mainly in CT36. The study population did not differ among the different calendar years analyzed in terms of age, gender, length of stay, or ward type (each p>0.2).Conclusion: This study revealed an increase in ST117 strains from 2008 to 2018, accompanied by a shift toward CT71 strains with the vanB genotype in 2018. We did not detect resistance or virulence traits in CT71 that could confer survival advantage compared to other CTs among ST117 strains. To date, it is not clear why ST117 and in particular strain type ST117 CT71 predominates over other strains.

Published: January 2020

Abstract
Background A routine blood examination is one of the most rapid, convenient and inexpensive clinical examinations that can reflect a patient’s inflammatory status and other blood conditions, and the prognostic value of routine preoperative blood parameters in MIBC patients is still unclear, so we evaluated the prognostic value of routine preoperative blood parameters in muscle-invasive bladder cancer (MIBC) following radical cystectomy (RC). Methods Data on 202 patients with MIBC who underwent RC at our institution were retrospectively collected between October 2007 and August 2018. The median preoperative neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and hemoglobin (HGB) values were used as cutoffs to form the low and high NLR, low and high PLR, and low and high HGB groups, respectively. The clinicopathologic characteristics of each group were compared by chi-square and t tests. Kaplan-Meier survival and multivariate Cox regression analyses were used to analyze prognosis. Results The median NLR, PLR and HGB values were 2.42, 112 and 125g/L, respectively. Kaplan-Meier results showed that the low HGB group had poor progression-free survival (PFS), cancer-specific survival (CSS) and overall survival (OS). A high NLR and high PLR groups correlated only with poor OS. Multivariate Cox analyses showed that pathological T3/4 stage, positive lymph node status and low HGB were independent risk factors for PFS, CSS and OS, and age was the only independent risk factor for OS. Conclusion Preoperative peripheral blood HGB is an independent risk factor for the prognosis of MIBC patients. These data suggest that HGB may be a useful prognostic marker for MIBC patients undergoing RC.
