The dynamic role of technological innovations and energy structure in China's industrial coal consumption growth: a joint production theoretical decomposition analysis.

China's energy-intensive industries utilize the leading proportion of coal to meet the demand for its industrial outputs, while on the other hand, these industries also assure the provision of livelihood to millions of people, and capping the share of coal consumption for these industries can adversely affect the industrial and economic growth of China. Thus, to achieve the Pareto improvement between environmental pollution and industrial output growth, it is essential to comprehend the patterns of coal consumption in these industries. Hence, the present research intended to analyze the potential drivers of coal consumption by applying a joint LMDI, DEA, and the production theoretical decomposition approach. Findings indices that, first, industrial output growth was the crucial driver to simulate the industrial coal consumption, while the potential coal intensity and coal technology changes exhibited the reverse effect. Second, the coal inputs and industrial output efficiency, along with the improvements in technological gaps, were found to be the imperative factors in decelerating coal consumption. Third, the energy industrial group was discovered to have more potentials of coal conversation as compared to the non-energy industrial group. Moreover, results also indicated that coal pure technical efficiency is accelerating coal growth, which revealed that coal can be saved by enhancing coal allocative efficiency. These findings laid the empirical ground to design a feasible coal conservation policy for achieving the imperative goals of environmental protection without compromising industrial output growth.

LYSTO: The Lymphocyte Assessment Hackathon and Benchmark Dataset.

We introduce LYSTO, the Lymphocyte Assessment Hackathon, which was held in conjunction with the MICCAI 2019 Conference in Shenzhen (China). The competition required participants to automatically assess the number of lymphocytes, in particular T-cells, in images of colon, breast, and prostate cancer stained with CD3 and CD8 immunohistochemistry. Differently from other challenges setup in medical image analysis, LYSTO participants were solely given a few hours to address this problem. In this paper, we describe the goal and the multi-phase organization of the hackathon; we describe the proposed methods and the on-site results. Additionally, we present post-competition results where we show how the presented methods perform on an independent set of lung cancer slides, which was not part of the initial competition, as well as a comparison on lymphocyte assessment between presented methods and a panel of pathologists. We show that some of the participants were capable to achieve pathologist-level performance at lymphocyte assessment. After the hackathon, LYSTO was left as a lightweight plug-and-play benchmark dataset on grand-challenge website, together with an automatic evaluation platform.

Assessment of consistency between peer-reviewed publications and clinical trial registrations in nursing journals.

BACKGROUND: The inconsistencies between randomized clinical trials (RCTs) registrations and peer-reviewed publications may distort trial results and threaten the validity of evidence-based medicine. Previous studies have found many inconsistencies between RCTs registrations and peer-reviewed publications, and outcome reporting bias is prevalent. AIMS: The aims of this review were to assess whether the primary outcomes and other data reported in publications and registered records in RCTs of nursing journals were consistent and whether discrepancies in the reporting of primary outcomes favored statistically significant results. Moreover, we reviewed the proportion of RCTs for prospective registration. METHODS: We systematically searched PubMed for RCTs published in the top 10 nursing journals between March 5, 2020, and March 5, 2022. Registration numbers were extracted from the publications, and registered records were identified from the registration platforms. The publications and registered records were compared to identify consistency. Inconsistencies were subdivided into discrepancies and omissions. RESULTS: A total of 70 RCTs published in seven journals were included. The inconsistencies involved sample size estimation (71.4%), random sequence generation (75.7%), allocation concealment (97.1%), blinding (82.9%), primary outcomes (60.0%) and secondary outcomes (84.3%). Among the inconsistencies in the primary outcomes, 21.4% were due to discrepancies and 38.6% resulted from omissions. Fifty-three percent (8/15) presented discrepancies in the primary outcomes that favored statistically significant results. Additionally, although only 40.0% of the studies were prospective registrations, the number of prospectively registered trials has trended upward over time. LINKING EVIDENCE TO ACTION: While not including all RCTs in the nursing field, our sample reflected a general trend: inconsistencies between publications and trial registrations were prevalent in the included nursing journals. Our research helps to provide a way to improve the transparency of research reports. Ensuring that clinical practice has access to transparent and reliable research results are essential to achieve the best possible evidence-based medicine.

Assessment of anterior chamber angle changes after phacoemulsification with swept-source OCT.

AIM: To assess the changes of anterior chamber angle in patients with shallow anterior chamber after phacoemulsification combined with intraocular lens (IOL) implantation, based on anterior segment swept-source optical coherence tomography (AS-SS-OCT) measurements. METHODS: This was a prospective case control study; sixty eyes of sixty case were scheduled for cataract surgery with normal intraocular pressure (IOP). Based on anterior chamber depth (ACD) and gonioscopy findings, the eyes were divided into two groups: group of shallow anterior chamber and narrow angle (SAC group, 30 eyes); and group of normal anterior chamber group with wide angle (NAC group, 30 eyes). Measurements of ACD, anterior chamber volume (ACV), iris volume (IV), lens vault (LV), angle opening distance (AOD), angle recess area (ARA), trabecular iris space area (TISA), and trabecular iris angle (TIA) were conducted in each group before and 3mo after surgery. RESULTS: There was no significant difference in age, axial length (AL), corneal curvature, corneal diameter, intraocular pressure, and IV between two groups before surgery, except for the LV (P=0.000). ACD and ACV were prominently larger in the NAC group than the SAC group 3mo after operation (3.69±0.38 vs 3.85±0.39 mm, P=0.025; 161.37±19.47 vs 178.26±20.30 mm3, P=0.002). AOD750, ARA750 in nasal and inferior quadrants, TISA750 in all quadrants except temporal, and TIA750 in all quadrants in SAC group were significantly smaller than those in NAC group after operation (all P<0.05). CONCLUSION: Cataract surgery can deepen anterior chamber and increase the width of anterior chamber angle in Chinese subjects, but the angle related parameters including AOD750, ARA750, TISA750, TIA, TISA750, and ACV in patients with shallow anterior chamber and narrow angle do not reach the normal level.

Depression in cancer: quality assessment of online patient education resources.

OBJECTIVE: Psychiatric comorbidities are common among cancer patients. However, little is known about the quality of online information regarding these conditions. This study uses a validated tool to systematically determine the strengths and limitations of websites addressing depression in cancer patients. METHODS: The term "depression in cancer patients" was searched online using the search engines Google, Yippy, and Dogpile. A set of predetermined inclusion/exclusion criteria was applied to all search results, which yielded 48 websites for inclusion. A validated rating tool was used to score the websites based on the six domains of Affiliation, Accountability, Interactivity, Structure & Organization, Readability, and Content Quality. The results were analyzed using descriptive statistics. RESULTS: Of the 48 websites evaluated, 50% were commercial. 63% of websites identified authorship, 54% cited reliable sources, 37% provided links, and 38% were updated within the last 2 years. 94% of websites featured a search engine and 60% had at least four structural tools. Average readability was at a grade 12.3 level using the Flesch-Kincaid scale and 11.3 using the Simple Measure of Gobbledygook Index. The most completely and accurately covered topics of depression were symptoms and treatment-83% and 73% respectively. Its prevention and prognosis were not covered by any of the websites. CONCLUSIONS: A validated rating tool was applied to evaluate the quality of online information for depression in cancer patients. Website accountability was poor, readability was often at a level that is too difficult for the lay audience, and the topics of prevention and prognosis were seldom covered.

Semiautomatic Assessment of the Terminal Ileum and Colon in Patients with Crohn Disease Using MRI (the VIGOR++ Project).

RATIONALE AND OBJECTIVES: The objective of this study was to develop and validate a predictive magnetic resonance imaging (MRI) activity score for ileocolonic Crohn disease activity based on both subjective and semiautomatic MRI features. MATERIALS AND METHODS: An MRI activity score (the "virtual gastrointestinal tract [VIGOR]" score) was developed from 27 validated magnetic resonance enterography datasets, including subjective radiologist observation of mural T2 signal and semiautomatic measurements of bowel wall thickness, excess volume, and dynamic contrast enhancement (initial slope of increase). A second subjective score was developed based on only radiologist observations. For validation, two observers applied both scores and three existing scores to a prospective dataset of 106 patients (59 women, median age 33) with known Crohn disease, using the endoscopic Crohn's Disease Endoscopic Index of Severity (CDEIS) as a reference standard. RESULTS: The VIGOR score (17.1 × initial slope of increase + 0.2 × excess volume + 2.3 × mural T2) and other activity scores all had comparable correlation to the CDEIS scores (observer 1: r = 0.58 and 0.59, and observer 2: r = 0.34-0.40 and 0.43-0.51, respectively). The VIGOR score, however, improved interobserver agreement compared to the other activity scores (intraclass correlation coefficient = 0.81 vs 0.44-0.59). A diagnostic accuracy of 80%-81% was seen for the VIGOR score, similar to the other scores. CONCLUSIONS: The VIGOR score achieves comparable accuracy to conventional MRI activity scores, but with significantly improved reproducibility, favoring its use for disease monitoring and therapy evaluation.

Economical and green synthesis of bagasse-derived fluorescent carbon dots for biomedical applications.

Carbon quantum dots (CDs) are promising nanomaterials in biomedical, photocatalytical and photoelectronic applications. However, determining how to explore an ideal precursor for a renewable carbon resource is still an interesting challenge. Here, for the first time, we report that renewable wastes of bagasse as a new precursor were prepared for fluorescent CDs by a hydrothermal carbonization (HTC) process. The characterization results show that such bagasse-derived CDs are monodispersed, contain quasi spherical particles with a diameter of about 1.8 nm and exhibit favorable photoluminescence properties, super-high photostability and good dispersibility in water. Most importantly, bagasse-derived CDs have good biocompatibility and can be easily and quickly internalized by living cancer cells; they can also be used for multicolour biolabeling and bioimaging in cancer cells. It is suggested that bagasse-derived CDs might have potential applications in biomedical and photoelectronic fields.

[Design and arrangement of the CHIP (CHinese In Prato) study]. / Disegno e modalità di realizzazione dello studio CHIP (CHinese In Prato).

Following the rapid economic development, China is experiencing a progressive increase in the incidence of cardiovascular (CV) events and in the prevalence of CV risk factors. According to recent estimations, the prevalence of diabetes sharply increased from 1% in 1980 to 11% in 2013. Migration from China to Europe is now mainly concentrated in Countries of the Southern Europe, e.g., Italy and Spain. The largest Chinese community living in Italy is now settled in Prato, being also one of the largest Chinese community in Europe. Local authorities estimate a number of Chinese citizens living in Prato of over 40,000 individuals, including illegal immigrants. The availability of reliable data on the health needs of Chinese population is thus a recognised priority for the local health system. The creation of a participatory research where Chinese population directly participates in the formation of a group of citizens involved in designing and conducting the survey allows to overcome difficulties due to the lack of official demographic files. Secondly, and most important, this approach makes it possible to effectively pass a prevention message to an elusive population. The purpose of the CHIP (CHinese In Prato) survey is to investigate the prevalence of diabetes and cardiovascular risk factors among Chinese immigrants. Recruitment procedure was started on 8th July 2014.

Evaluation of conventional, dynamic contrast enhanced and diffusion weighted MRI for quantitative Crohn's disease assessment with histopathology of surgical specimens.

OBJECTIVES: To prospectively compare conventional MRI sequences, dynamic contrast enhanced (DCE) MRI and diffusion weighted imaging (DWI) with histopathology of surgical specimens in Crohn's disease. METHODS: 3-T MR enterography was performed in consecutive Crohn's disease patients scheduled for surgery within 4 weeks. One to four sections of interest per patient were chosen for analysis. Evaluated parameters included mural thickness, T1 ratio, T2 ratio; on DCE-MRI maximum enhancement (ME), initial slope of increase (ISI), time-to-peak (TTP); and on DWI apparent diffusion coefficient (ADC). These were compared with location-matched histopathological grading of inflammation (AIS) and fibrosis (FS) using Spearman correlation, Kruskal-Wallis and Chi-squared tests. RESULTS: Twenty patients (mean age 38 years, 12 female) were included and 50 sections (35 terminal ileum, 11 ascending colon, 2 transverse colon, 2 descending colon) were matched to AIS and FS. Mural thickness, T1 ratio, T2 ratio, ME and ISI correlated significantly with AIS, with moderate correlation (r = 0.634, 0.392, 0.485, 0.509, 0.525, respectively; all P < 0.05). Mural thickness, T1 ratio, T2 ratio, ME, ISI and ADC correlated significantly with FS (all P < 0.05). CONCLUSIONS: Quantitative parameters from conventional, DCE-MRI and DWI sequences correlate with histopathological scores of surgical specimens. DCE-MRI and DWI parameters provide additional information. KEY POINTS: • Conventional MR enterography can be used to assess Crohn's disease activity. • Several MRI parameters correlate with inflammation and fibrosis scores from histopathology. • Dynamic contrast enhanced imaging and diffusion weighted imaging give additional information. • Quantitative MRI parameters can be used as biomarkers to evaluate Crohn's disease activity.

[Investigation of differences in subjective demand for orthodontic treatment of middle school students in zones with different economic levels].

OBJECTIVE: To investigate the acquaintance to orthodontics and possible factors that obstruct orthodontic treatment in middle school students in zones with different economic levels in Jiangjin, Chongqing. METHODS: The students were randomly divided into four groups: A class from a junior high school in town (group 1), a class from a senior high school in town (group 2), a class from a junior high school in the countryside (group 3), a class from a senior high school in the countryside (group 4). The information was collected by questionnaire, and the statistical analysis of results was carried out by SPSS 17.0 software. RESULTS: Sex made difference in the acquaintance to orthodontics treatment. Girls worried more about teeth extraction and pain that may occur during treatment than the boys. Students in the city had more access to related consultations compared to those in the countryside. Different economic conditions made much contribution to the proportion to go for orthodontics treatment in cities and rural areas. The evaluation from families and friends may affect patients' subjective estimation to themselves. CONCLUSION: Orthodontists should learn more about student patiens from various aspects, and make different therapies according to their sexes, economic conditions of family, education levels, etc. Only so can orthodontists get better compliance from their patients.

Computational modeling for assessment of IBD: to be or not to be?

The grading of inflammatory bowel disease (IBD) severity is important to determine the proper treatment strategy and to quantify the response to treatment. Traditionally, ileocolonoscopy is considered the reference standard for assessment of IBD. However, the procedure is invasive and requires extensive bowel preparation. Magnetic resonance imaging (MRI) has become an important tool for determining the presence of disease activity. Unfortunately, only moderate interobserver agreement is reported for most of the radiological severity measures. There is a clear demand for automated evaluation of MR images in Crohn's disease (CD). This paper aims to introduce a preliminary suite of fundamental tools for assessment of CD severity. It involves procedures for image analysis, classification and visualization to predict the colonoscopy disease scores.

Neural representations of social status hierarchy in human inferior parietal cortex.

Mental representations of social status hierarchy share properties with that of numbers. Previous neuroimaging studies have shown that the neural representation of numerical magnitude lies within a network of regions within inferior parietal cortex. However the neural basis of social status hierarchy remains unknown. Using fMRI, we studied subjects while they compared social status magnitude of people, objects and symbols, as well as numerical magnitude. Both social status and number comparisons recruited bilateral intraparietal sulci. We also observed a semantic distance effect whereby neural activity within bilateral intraparietal sulci increased for semantically close relative to far numerical and social status comparisons. These results demonstrate that social status and number comparisons recruit distinct and overlapping neuronal representations within human inferior parietal cortex.
