In this work we have studied the state-of-the-art machine learning algorithms and proposed an attention network which can grade retinal images. The proposed method is validated on a public dataset EIARG1, which is only publicly available dataset for such task as per our knowledge.
Deoxycholic acid (DCA), a secondary bile acid, is reportedly increased in the serum of patients with nonalcoholic steatohepatitis and animals with experimentally induced hepatocellular carcinoma (HCC), but its contribution to malignant behaviors of HCC has not been precisely clarified. This study aimed to examine the effect of DCA on hepatic stellate cells (HSCs), a major component of nonparenchymal cells in the liver, and its subsequent indirect effect on HCC cells.
LX2 cells, a human HSC line, were treated with DCA in vitro. Then, HuH7 cells, a human hepatoma cell line, were incubated in conditioned media of DCA-treated LX2 to investigate the subsequent effect focusing on malignant behaviors.
DCA resulted in cellular senescence in LX2 with the decreased cell proliferation via cell cycle arrest at G0/1 phase, together with the induction of senescence-associated secretory phenotype (SASP) factors. To investigate the influence of SASP factors secreted by HSCs in response to DCA, HCC cells were treated with conditioned media that promoted cell migration and invasion via induction of epithelial mesenchymal transition. These changes were attenuated in the presence of neutralizing antibody against IL8 or TGFβ. Pathological analysis of surgical specimens from HCC patients revealed that senescent HSCs were detected in the stroma surrounding HCC.
Our data suggest an important role of HSC senescence caused by DCA for the malignant biological behaviors of HCC via induction of SASP factors, particularly IL8 and TGFβ.

We examined the prevalence trends of KS in subgroups of age, sex and race in the US and identified relevant laboratory factors associated with a history of KS using National Health and Nutrition Examination Survey (NHANES) data. We conducted a cross-sectional study among 28,209 US adults aged ≥ 20 years old in the NHANES from 2007 to 2016. We calculated the prevalence of a self-reported history of KS by using weights and standardized to the 2010 US Census population. We also compared relevant laboratory values according to the history of KS. The prevalence of KS decreased from 8.7% in 2007-2008 to 7.2% in 2011-2012 but then increased to 9.0% in 2013-2014 and 10.1% in 2015-2016. However, the overall prevalence of KS increased over 2007-2016 (p-trend = 0.02). Prevalence of KS among men was higher than women. Among men aged 20-79, there were significant qua-specific prevalence values emphasizes the importance of looking at long-term trends and using more than a single 2-year cycle in analyses to increase the precision of the estimate. However, there was an overall increase in the prevalence of KS over 2007-2016.
Controversy exists with regards to the etiology and treatment of lateral epicondylitis and the role of the lateral capsule in this pathology. The aim of this study was to compare arthroscopic lateral capsule resection with or without extensor carpi radialis brevis (ECRB) tendon debridement for treatment of lateral epicondylitis.
This is a retrospective study of 38 patients who underwent arthroscopic surgery for LE with two different techniques Eighteen patients were treated with arthroscopic lateral capsular resection (LCR) + ECRB debridement and 20 patients were treated with arthroscopic LCR alone, without ECRB debridement. Both groups were assessed with Quick Disabilities of the Arm, Shoulder and Hand (QDASH) score for function and Visual Analog Scale (VAS) score for pain.
Quick DASH scores were 12 [Formula see text] 5 and 13 [Formula see text] 4 at Groups 1 and 2, respectively, without any statistically significant difference. VAS pain scores were 15 [Formula see text] 2 for both groups. VAS function scores were 85 [Formula see text] 22 and 86 [Formula see text] 18 at Groups 1 and 2 respectively. Sick leave periods in terms of weeks were 7 [Formula see text] 5 and 7 [Formula see text] 4 at Groups 1 and 2, respectively. There was no statistically significant difference in outcome of the two groups compared in terms of VAS pain, function scores, failure (re-operation) rates and sick leave period at the end of final follow-up.
Both arthroscopic LCR alone and Arthroscopic LCR with ECRB debridement for the management of refractory LE provide significant improvement in pain and function. Isolated Arthroscopic LCR could be a sufficient surgical treatment for refractory LE. Thus, ECRB debridement or release may not be necessary in every case.

IV.Maternal psychosocial stress may impact child neurodevelopment, but little is known regarding psychosocial job strain. HS-10296 molecular weight We hypothesized high psychosocial job strain during pregnancy was associated with behavioural problems in the 11-year-old children. Mothers in the Danish National Birth Cohort (1996-2002) were included if they worked, provided information on job strain [Karasek's model high job strain (often job demand/seldom job control) and passive (seldom or sometimes job demands/seldom job control)] during early pregnancy. At the 11-year follow-up, children (N = 30,592), mothers (N = 30,993), and teachers (N = 12,810) responded to the Strength and Difficulties Questionnaire (SDQ), a screening tool for child behaviour. Scores for hyperactivity, conduct, emotional and peer problems were dichotomised [80% (no) vs. 20% (yes)] according to Danish norms (yes/no). Maternal job strain was not associated with behavioural problems with teachers as informants. When assessed by child or mother, high maternal job strain increased risk of child behavioural problems, but risks were more pronounced for mothers in passive jobs [maternal assessment of total difficulties/odds ratio (95% confidence interval) high strain-girls 1.16 (0.97-1.40); boys 1.24 (1.02-1.50). Passive girls 1.43 (1.21-1.68); boys 1.25 (1.05-1.49)]. This is one of the first studies on this topic. The different types of maternal job strain were partly associated with child behavioural problems at 11 years; more so if mothers worked in passive rather than the hypothesized high strain jobs. Findings showing dependency on informant could not only indicate unmeasured confounding or rater's bias, but also selection in the smaller numbers of teacher informants or different environments of interaction with the children.
