Abstract
Background: Intramedullary nails have become the main treatment for intertrochanteric fractures. However, distal locking procedure during nailing gradually raised controversy. A systematic review and meta-analysis of clinical trials was performed to summarize the existing evidence with the aim at determining the safety and efficacy of distal locking or unlocking in the nailing of stable intertrochanteric fractures. Methods: Appropriate articles were identified using the most common public databases such as PubMed, Embase, the Cochrane Library, and Google Scholar from the inception of each database to April 2019, without restriction of language, publication date, and also considering ongoing trials. Eligible studies were represented by randomized controlled trials or retrospective cohort studies comparing distal locking with unlocking for the treatment of acute stable intertrochanteric fractures in adult patients. Information regarding the methodological quality, patient demographics and all clinical outcomes were extracted independently by two reviewers. Patients were then divided into locking and unlocking group. Results: This study included 9 articles, a total of 1978 patients with a similar baseline. The results showed that the unlocking group had shorter operation time, less intraoperative bleeding, lower transfusion rate, and less thigh pain after the treatment of femoral intertrochanteric fracture compared with the distal locking group. No significant difference was found in safety-related outcomes including mortality, infection rate, cutting out, loss of reduction, backing out of lag screws, cephalic screw breakage, nail breakage, and peri-implant fractures between the two groups. Efficacy-related outcomes including nonunion, delayed healing rates, and Harris functional score were also not significantly different between the two groups. Conclusions: Our pooled analysis demonstrated that the distal unlocking of the stable intertrochanteric fractures can shorten the operation time, reduce intraoperative bleeding, and reduce the blood transfusion rate. The use of locked or unlocked intramedullary nailing does not affect long-term outcomes in terms of complications and function.

Abstract
Background: Creating a case formulation is an important and basic skill in psychotherapy meant to guide treatment. A patient’s interpersonal pattern is an essential part of a case formulation. Core Conflictual Relationship Theme (CCRT) is a well-known structured method to describe interpersonal patterns. The CCRT method is based on the assumption that humans display a central relationship theme, which is shown in most relationships as well as in the patient-therapist relation. The CCRT scoring is based on how the patient describes interactions with others, in therapy sessions or in a specific interview. These descriptions are transcribed. Raters then score the identified relational episodes by choosing elements from the clustered categories of Wishes, Response from Others and Response from Self. The method has shown high validity and reliability. Inter rater reliability is generally good: Cohen’s kappa ranging from 0.55 to 0.70. To decide CCRT pattern from transcribed material is time consuming and labour intensive This study investigates a labour- and timesaving version of the method.Methods: This study aimed to investigate rater agreement in a simplified method of scoring the CCRT, based directly on live semi-structured dynamic interviews without transcribing the material. 52 patients referred for psychotherapy in a clinical trial, were scored for CCRT pattern. Based on information that came forth during the two-hour interview, raters scored the patients choosing elements from the clustered categories of Wishes, Response from Others and Response from Self. More than one category in each component could be chosen without ranking. 5 raters compared two by two were investigated. Inter rater reliability was measured by Cohen’s kappa.Results: Mean kappa for Wishes, Response from Others and Response from Self was .33, .44 and .45 respectively. Mean kappa for CCRT in total was .44 among 5 raters.Conclusion: In this simplified method to score the CCRT based on oral dynamic interviews, fair to moderate IRR was obtained.

Abstract
BackgroundCarbofuran was a widely used board-spectrum pesticide, which despite his strict regulation and bans for more than one decade is still encountered in cases of intentional poisoning in dogs and wildlife. The objective of the study was to provide a complete and detailed description of the pathological, histological and toxicological findings of the 7 cases of intentional carbofuran poisoning in dogs. ResultsIn this retrospective study 7 case of carbofuran intoxication recorded from July 2015 to June 2017 were analyzed. Following complete history recording, all cases were examined by complete necropsy and histopathology. The carbofuran intoxication was confirmed in all cases by gas-chromatography. The postmortem examination revealed extensive haemorrhages and congestion located mainly within the respiratory, nervous and cardiovascular systems, accompanied by degeneration and necrosis within the lung, heart and kidneys.ConclusionsNowadays in the European Union, carbamate poisoning is a rarely reported entity. Although banned in the EU, carbofuran is still used in Romania for crop protection and poisoning cases are encountered in animals, and it can be purchased. This paper will contribute to a better understanding of occurrence and pathogenesis in cases of acute carbofuran exposure in dogs and add some necropsy and histopathology data to current literature.

Abstract
Background: Cervical cancer is caused by high-risk Human Papillomavirus (hr-HPV) infection associated with cofactors that has been analyzed as predictors of cytological abnormalities remission or persistence. These cofactors may be classified as environmental, epigenetic or genetic. Polymorphism in genes of enzymes that act on one-carbon metabolism alter their activity and may be associated with cervical carcinogenesis because they affect DNA synthesis and repair, and gene expression. Therefore, the objective of this study was to analyze the risk of persistence of pre-neoplastic cervical lesions according to genetic polymorphisms involved in one-carbon metabolism. Sample group was divided in Remission (n=60) - presence of pre-neoplastic lesion at first meeting (T1), and normal cytology after six months of follow-up (T2), and Persistence (n=46) - presence of pre-neoplastic lesion at T1 and T2. Cervical samples were obtained for cytological analysis (T1 and T2), HPV detection (T1), and evaluation of polymorphism C667T of Methylenetetrahydrofolate Reductase (MTHFR C677T), A2756G of Methionine Synthase (MS A2756G), A66G of Methionine Synthase Reductase (MTRR A66G), double or triple 28 bp tandem repeat in 5'-untranslated enhanced region of Thymidylate Synthase (TSER), and 6 bp deletion at nucleotide1494 in TS 3'-untranslated region (TS3'UTR). Genetic Risk Score (GRS) was calculated for analyze all genetic polymorphism simultaneously. Results: No differences were observed between Remission and Persistence groups of GRS, or genotypic and allelic distribution of MTHFR C677T and MS A2756G polymorphisms. However, higher risk of persistence was observed among women presenting heterozygote genotype - ins/del [OR (IC95%): 3.22 (1.19 – 8.69), p=0.021], or polymorphic genotype – del/del [OR (IC95%): 6.50 (1.71 – 24.70), p=0.006] of TS3’UTR. Conclusions: Presence of TS3’UTR polymorphism increased risk of persistence of cervical abnormalities. This genetic variant could be considered as potential marker of cervical carcinogenesis, assisting follow-up of women with persistent pre-neoplastic cervical lesions.

Abstract
Background: Prior studies have shown that contraceptive use reduces maternal mortality independently of other maternal health services. The present study took advantage of geographically detailed Indonesian data to study the interplay between contraceptive use and other risk and protective factors for maternal mortality at the community level, a level of analysis where the protective effects of family planning can be best understood.Methods: Data from the 2015 Intercensal Population Survey (SUPAS) and the 2014 Village Potential Survey (PODES) were used to construct a series of census block-level variables measuring key risk and protective factors for maternal mortality. The relationships between these factors and maternal mortality, measured via natural log-transformation of past five-year maternal mortality ratios in each of the 40,748 census blocks were assessed via log-linear regressions.Results: Higher community maternal mortality ratios were associated with lower community contraceptive prevalence, higher percentage of parity four-plus births, higher proportion of poor households, lower population density of hospitals, higher density of traditional birth attendants (TBA), and residence outside of Java-Bali. For every percentage point increase in CPR, community maternal mortality ratios were lower by 7.8 points. Community-level household wealth was the strongest predictor of maternal mortality.Conclusions: Community contraceptive prevalence made a significant contribution to reducing maternal mortality net of other risk and protective factors during 2010-2015. Increased health system responsiveness to the needs of pregnant women and reductions in socioeconomic and geographic disparities in maternal health services will be needed for Indonesia to reach the 2030 SDG maternal mortality goal.

Abstract
Objectives: The impact of Influenza infection on Hospital resources and patient management is significant. Timely implementation of infection control and treatment can significantly reduce the impact during a time when demand for acute Hospital resources is at peak. Turnaround times of Laboratory based screening tests for the diagnosis of influenza may have an impact on the implementation of infection control measures and treatment. In this study the objectives included determining the correlation between the Abbott ID NOW point of care testing (POCT) instrument using the Influenza A&B2 test and the laboratory based GeneXpert Flu+RSV kit. In addition the impact of the POCT instrument on the prescription of antivirals and antibiotics was evaluated by comparing with practice when the instrument was not in place. Results: The results of the correlation study revealed the Abbott ID NOW POCT has 92% sensitivity for the detection of Influenza A, while specificity was 100% for both Influenza A and B. The impact of the POCT instrument on the frequency of prescription of antivirals and amount of antibiotics consumed (33% reduction in antibiotic consumption) was significant. In addition the average patient length of Hospital stay was significantly reduced from 5.26 days to 3.73 days.

Abstract
Background: Understanding the genetic diversity in threatened species that occur in forest remnants is necessary to establish efficient strategies for the species conservation, restoration and management. Panax vietnamensis Ha et Grushv. is medicinally important, endemic and endangered species of Vietnam. However, genetic diversity and structure of population is unknown due to lack of efficient molecular markers. Results: In this study, we employed Illumina HiSeq TM 4000 sequencing to analyze the transcriptomes of P. vietnamensis (roots, leaves and stems). A total of 23,741,783 raw reads were obtained and assembled, from which, 89,271 unigenes with an average length of 598.3191 nt were generated. During functional annotation, 31,686 unigenes were annotated in Gene Ontology categories, Kyoto Encyclopedia of Genes and Genomes pathways, Swiss-Prot database, and Nucleotide Collection (NR/NT) database. In addition, 11,343 expressed sequence tag-simple sequence repeat (EST-SSRs) were detected. From 7,774 primer pairs, 101 were selected for polymorphism validation, in which, 20 primer pairs were successfully amplified to DNA fragments and significant amounts of polymorphism was observed within population. The nine polymorphic microsatellite loci were used to analyze genetic diversity and structure of the natural populations. The obtained results revealed that the shows high levels of genetic diversity in populations, the average observed and expected heterozygosity were H O = 0.422 and H E = 0.479. During the Bottleneck analysis using TPM and SMM models (p < 0.01) shows that targeted population is significantly heterozygote deficient. This suggests sign of bottleneck in all populations. Genetic differentiation among populations was moderate (F ST = 0.133) and indicating limited gene flow (Nm = 1.63). Analysis of molecular variance (AMOVA) showed 63.17% of variation within individuals and 12.45% among populations. These results showed a moderate genetic structure of P. vietnamensis. STRUCTURE analysis and the unweighted pair-group method with arithmetic means (UPGMA) tree revealed strong genetic structure and two genetic clusters related to geographical distances, as well. Conclusion: Our study will assist conservators in future conservation management, breeding, production and habitats restoration of the species.

Transcriptomic and physiological analyses of rice seedlings under different nitrogen supplies provide insight into the regulation involved in axillary bud outgrowth
Authors: Wang Rongna , Qian Junjie , Fang Zhongming , Tang Jihua 
Published: December 2019

Abstract
Background: N is an important macronutrient required for plant development and significantly influences axillary bud outgrowth, which affects tillering and grain yields of rice. However, how different N concentrations affect axillary bud growth at the molecular and transcriptional levels remains unclear. Results: In this study, morphological changes in the axillary bud growth of rice seedlings under different N concentrations ranging from low to high levels were systematically observed. To investigate the expression of N-induced genes involved in axillary bud growth, we used RNA-seq technology to generate mRNA transcriptomic data from two tissue types, basal parts and axillary buds, of plants grown under six different N concentrations. In total, 10,221 and 12,180 DEGs induced by LN or HN supplies were identified in the basal parts and axillary buds, respectively, via comparisons to expression levels under NN level. Analysis of the coexpression modules from the DEGs of the basal parts and axillary buds revealed an abundance of related biological processes underlying the axillary bud growth of plants under N treatments. Among these processes, the activity of cell division and expansion was positively correlated with the growth rate of axillary buds of plants grown under different N supplies. Additionally, TFs and phytohormones were shown to play crucial roles in determining the axillary bud growth of plants grown under different N concentrations. Further validation of OsGS1;2 and OsGS2 , the rice mutants of which presented altered tiller numbers, validated our transcriptomic data. Conclusion: These results indicate that different N concentrations affect the axillary bud growth rate, and our study revealed comprehensive expression profiles of genes that respond to different N concentrations, providing an important resource for future studies attempting to determine how axillary bud growth is controlled by different N supplies.

Abstract
Background This study aimed to assess the prognostic factors including low skeletal muscle mass index (SMI) and perioperative blood transfusion for patients with hepatocellular carcinoma (HCC) following curative surgery.Methods This study included 139 patients with HCC who underwent hepatectomy between 2005 and 2016. Univariate and multivariate analyses were performed to identify variables associated with overall survival (OS) and recurrence-free survival (RFS).Results Low SMI was significantly related with poor OS, while blood transfusion had a strong impact on RFS. The male ratio and body mass index in the low SMI group were significantly higher than those in the high SMI group. There were no significant differences in age, virus aetiology, laboratory data, liver function, tumour makers, and operative variables between the groups. Tumour factors such as tumour diameter, tumour number, poor differentiation, and intrahepatic metastasis (IM) did not significantly differ between the two groups. Operation time, intraoperative blood loss volume, and recurrence ratio were significantly higher in the blood transfusion group than in the non-transfusion group. IM was associated with poor OS and RFS.Conclusions Multidisciplinary support for recovering low SMI and reducing the use of blood transfusion would improve the long-term outcomes in patients with HCC following curative surgery. Low SMI and blood transfusion were independently related with long-term prognosis in patients with HCC following curative surgery.

Published: December 2019

Abstract
This study investigates the solar photo-Fenton based decolorization of a cationic dye methylene blue (MB) at circumneutral pH conditions. Water-soluble Fe(III)-citrate complex was used as a source of Fe(II) during the reaction by ligand-to-metal charge transfer under solar irradiation, and consequently, for the production of hydroxyl radicals. Solar decolorization of methylene blue was studied in sunny as well as cloudy weather, and further optimized using response surface methodology and Box-Behnken statistical experimental design. In this model, Fe(III) dose, citrate ion dose, and initial pH of the solution were used as independent parameters, and percentage decolorization of MB was used as a response. Better decolorization of MB was observed in sunny weather as compared to cloudy weather. A particular combination of parameters, i.e. pH of 7, Fe(III) of 0.5 mM, and citrate ion concentration of 10 mM, was found to achieve 89.19% and 51.22% decolorization in sunny and in cloudy weather respectively, which were the optimum/near-optimum performances for these weather conditions. Hence the process initiated with these parameters may potentially achieve better performance than any other parameter combination in all weathers, although the absolute removal would still depend on incident solar irradiation.

Authors: Zhao Xin , Feng Panfeng , He Wenqian , Du Xing , Chen Chao , Suo Lianhuan , Liang Min , Zhang Na , Na An , Zhang Yan 
Published: December 2019

Background:
Anthocyanins are a type of flavonoids that are natural water soluble glycosidic pigments
with efficacious anti-cancer effects, which have good biological activity against many cancers including colorectal
cancer (CRC). However, the exact molecular mechanism used by anthocyanins against cancer is unclear; it is
also unclear what a reasonable dosage might be for their use against colorectal cancer.

Methods:
Western blotting, immunohistochemistry, MTT assay, xenograft model, and hematoxylin-eosin (HE)
staining were used to perform the experiments.

Results:
Compared with the control group, anthocyanins could significantly inhibit the cell viability and proliferation
and promote the apoptosis of human colon cancer HT29 cells. Furthermore, anthocyanins reduced tumor
weight and volume in a colon tumor mouse model and downregulated the expression of PI3K protein, inhibited
AKT expression and phosphorylation, decreased the Bcl-2 and Bax ratio and reduced survivin protein expression
in the tumor tissue.

Conclusion:
Anthocyanins promoted apoptosis of CRC cells and inhibited colon cancer growth of xenografted
tumors. Mechanistically, anthocyanins enhanced the Bcl-2/Bax and caspase-dependent apoptotic pathways
through targeting the PI3K/AKT/survivin pathway, resulting in impairment of growth of CRC.
