Abstract
Study question
What is the live birth rate after single, low-grade blastocyst (LGB) transfer?
Summary answer
The live birth rate for LGBs is 28%, ranging between 15–31% for the different inner cell mass (ICM) and trophectoderm (TE) subgroups of LGBs.
What is known already
Live birth rates following LGB transfer are varied and have been reported to be in the range of 5–39%. However, these estimates are inaccurate as studies investigating live birth rates following LGB transfer are inherently limited by sample size (n = 10–440 for LGB transfers) due to LGBs being ranked last for transfer. Further, these studies are heterogenous with varied LGB definitions and design. Collating LGB live birth data from multiple clinics is warranted to obtain sufficient numbers of LGB transfers to establish reliable live birth rates, and to allow for delineation of different LGB subgroups, including blastocyst age and female age.
Study design, size, duration
We performed a multicentre, multinational retrospective cohort study in 9 IVF centres in China and New Zealand from 2012 to 2019. We studied the outcome of 6966 single blastocyst transfer cycles on days 5–7 (fresh and frozen) according to blastocyst grade, including 875 transfers from LGBs (<3bb, this being the threshold typically applied to LGB studies). Blastocysts with expansion stage 1 or 2 (early blastocysts) were excluded.
Participants/materials, setting, methods
The main outcome measured was live birth rate. Blastocysts were grouped according to quality grade: good-grade blastocysts (GGBs; n = 3849, aa, ab and ba), moderate-grade blastocysts (MGBs; n = 2242, bb) and LGBs (n = 875, ac, ca, bc, cb and cc) and live birth rates compared using the Pearson Chi-squared test. A logistic regression analysis explored the relationship between blastocyst grade and live birth after adjustment for the confounders: clinic, female age, expansion stage, and blastocyst age.
Main results and the role of chance
The live birth rates for GGBs, MGBs and LGBs were 45%, 36% and 28% respectively (p < 0.0001). Within the LGB group, the highest live birth rates were for grade c TE (30%) and the lowest were for grade c ICM (19%). The lowest combined grade (cc) maintained a 15% live birth rate (n = 7/48). After accounting for confounding factors, including female age and blastocyst characteristics, the odds of live birth were 2.33 (95% CI = 1.88–2.89) for GGBs compared to LGBs and 1.56 (95% CI = 1.28–1.92) for MGBs compared to LGBs following fresh and frozen blastocyst transfers (p < 0.0001, odds ratios confirmed in exclusively frozen blastocyst transfer cycles). When stratified by individual ICM and TE grade, the odds of live birth according to ICM grade were 1.31 (a versus b; 95% CI = 1.15–1.48), 2.82 (a versus c; 95% CI = 1.91–4.18) and 2.16 (b versus c; 95% CI = 1.48–3.16; all p < 0.0001). The odds of live birth according to TE grade were 1.33 (a versus b; 95% CI = 1.17–1.50, p < 0.0001), 1.85 (a versus c; 95% CI = 1.45–2.34, p < 0.0001) and 1.39 (b versus c; 95% CI = 1.12–1.73, p = 0.0024).
Limitations, reasons for caution
Despite the large multicentre design of the study, analyses of transfers occurring within the smallest subsets of the LGB group were limited by sample size. The study was not randomised and had a retrospective character.
Wider implications of the findings: LGBs maintain satisfactory live birth rates (averaging 28%) in the general IVF population. Even those in the lowest grading tier maintain modest live birth rates (15%; cc). It is recommended that LGBs not be universally discarded, and instead considered for subsequent frozen embryo transfer to maximize cumulative live birth rates.

Abstract
Objective: To investigate the relationship between clinicopathologic features and prognosis of pancreatic ductal adenocarcinoma located in the head of pancreas. Methods: A retrospective study was performed on 169 patients undergoing radical resection for pancreatic head cancer collected in the First Affiliated Hospital with Nanjing Medical University from January 2018 to April 2019. Univariate analysis and multivariate analysis were performed. Results: Patient's age, tumor differentiation, tumor maximum diameter, resection margin (several resection margins including portal vein groove resection margin, posterior resection margin, and uncinate resection margin), number of positive lymph nodes, number of regional lymph node dissected, and some preoperative and postoperative indicators were associated with prognosis (P<0.05). Direct tumor invasion of organs and surrounding tissues, perineural and vascular invasion, pathologic variants etc. had no statistical significance for survival time. Patient's age, maximum tumor diameter, degree of differentiation, uncinate incision margin, number of regional lymph nodes dissected, and preoperative CA19-9 were independent factors affecting prognosis. Patients older than 74 years of age, with tumors larger than 3 cm in diameter, poorly differentiated, less than 7 regional lymph node dissected, positive uncinate margin, and preoperative CA19-9 higher than 1.5×105 U/L were independent risk factors in patients with pancreatic head cancer. Conclusions: Old age, tumor lager than 3 cm, poor differentiation, low examined lymph nodes, direct uncinate margin involvement and (or) with preoperative CA19-9 higher than 1.5×105 U/L are related to poor prognosis of head pancreatic cancer.

Abstract
Iron overload is positively associated with diabetes risk. However, the role of iron in adipose tissue remains incompletely understood. Here, we report that transferrin-receptor-1-mediated iron uptake is differentially required for distinct subtypes of adipocytes. Notably, adipocyte-specific transferrin receptor 1 deficiency substantially protects mice from high-fat-diet-induced metabolic disorders. Mechanistically, low cellular iron levels have a positive impact on the health of the white adipose tissue and can restrict lipid absorption from the intestine through modulation of vesicular transport in enterocytes following high-fat diet feeding. Specific reduction of adipocyte iron by AAV-mediated overexpression of the iron exporter Ferroportin1 in adult mice effectively mimics these protective effects. In summary, our studies highlight an important role of adipocyte iron in the maintenance of systemic metabolism through an adipocyte-enterocyte axis, offering an additional level of control over caloric influx into the system after feeding by regulating intestinal lipid absorption.

Abstract
ABSTRACT Foods of animal origin, such as poultry, eggs, and pork, are recognized sources of Salmonella infections, but determination of the proportion of foodborne infections associated with various food sources has been challenging. In the present study, 141 Salmonella isolates recovered from 1,322 poultry product samples purchased over a 1-year period from retail stores across Seattle, WA were subtyped by pulsed-field gel electrophoresis (PFGE) using restriction enzyme XbaI. The objectives of the study were (i) to analyze the longitudinal distribution of Salmonella PFGE profiles throughout the sampling period and their clonality within and between poultry processing establishments, (ii) to determine the association between PFGE profiles of Salmonella isolates from locally distributed poultry products and those of clinical isolates submitted to the Washington State Department of Health (WA-DOH) laboratories, and (iii) to compare the PFGE profiles of Salmonella isolates from the National Antimicrobial Resistance Monitoring System (NARMS) retail meats program. During the 1-year sampling period, multiple indistinguishable PFGE patterns were found across multiple poultry processing establishments. Twelve of the 30 unique PFGE profiles of Salmonella isolates from locally purchased poultry products were indistinguishable from the PFGE profiles of clinical Salmonella isolates submitted to the WA-DOH. When the PFGE profiles from the poultry samples were compared with those found in the NARMS database, eight indistinguishable PFGE matches were found with isolates recovered from chicken breasts, ground turkey, and ground beef from multiple states. Although this study revealed some association between PFGE profiles from raw poultry products and those of clinical isolates from the same geographical area, these results do not prove that all of those clinical isolates were from infections acquired through consumption or handling of poultry.

Abstract
Objective: To evaluate the effectiveness of thermal ablation in the treatment of human papillomavirus (HPV) infection and cervical intraepithelial neoplasia (CIN) in Chinese women. Methods: The high-risk HPV-positive women aged 20-65 who were detected through a cervical cancer screening project implemented in three rural sites (Etuoke counties in Inner Mongolia, Xiangyuan and Yangcheng counties in Shanxi Province) and one urban site (Shenzhen) in China were included in this prospective study. Follow up evaluation was performed on HPV positive women who underwent thermal ablation (n=166) as well as received no treatment (n=2 716) in cervical cancer screening program. For women with thermal ablation treatment, HPV test and cytology were used for follow-up with the interval of 6 months or longer after treatment. For women without treatment, HPV test was used for annual follow-up. Women with positive results in either of the HPV tests or abnormal cytology were referred for a colposcopy or biopsy if necessary. The HPV clearance rate and the cure rate of CIN were compared between the two groups. Results: A total of 152 women treated with thermal ablation and 2 539 women without treatment reported for follow-up evaluation with the age M(Q1, Q3) of 42 (36, 48) and 47 (41, 54) years old, and the median time to follow-up time of 23.4 (12.4, 24.5) and 23.5 (12.4, 24.0)months, respectively. The HPV clearance rate in women undergoing thermal ablation was significantly higher than that in women with no treatment (73.0% vs 46.1%, P<0.001). The HPV16, HPV52 and HPV58 clearance rates among women receiving thermal ablation were higher than that in women without treatment with the OR (95%CI) of 2.8 (1.3-6.1), 3.2 (1.3-7.9) and 5.8 (2.1-15.6). For women with histologically confirmed CIN at baseline, cure rates were 77.4%(n=72) for thermal ablation. Cure rates of the thermal ablation were 81.0%(n=47) for CIN grade one (CIN1) and 71.4% (n=25) for CIN grade two or worse (CIN2+). Conclusions: Thermal ablation is effective to clear the HPV infection as well as to treat CIN. Particularly for the HPV genotypes with the paramount attributable proportion to cervical cancer and precancerous in China, the HPV clearance rate was significantly higher than that reported in the women without treatment.

Abstract
Available data suggests that granulated aerogels can be of interest in terms of their sound absorption performance in the audio frequency range. However, there is still no thorough understanding of the complex physical phenomena which are responsible for their observed acoustical properties. This work is an attempt to address this gap through advanced material characterization methods and mathematical modelling. Aerogel samples are produced through a two-step, acid-base sol-gel process, with sol silica concentration and density being the main variables. Their pore structure is carefully characterized by nitrogen sorption analysis and scanning electron microscopy. The acoustical properties of hard-backed granular silica aerogels are measured in an impedance tube and the results predicted accurately with the adopted theoretical model. Although silica aerogels have over 90% of open interconnected pores, this was neither reflected in the measured acoustical properties nor the parameter values predicted with the model. Novel results show that only a proportion of the micro and mesopores in the direct vicinity of the grain surface influenced the acoustical properties of aerogels. Further work in the hierarchical pore structure of aerogels is required to better understand the roles of different pore scales on the measured acoustical properties of a granulated aerogel.

Abstract
OBJECTIVE To evaluate the efficiency of a recombinase-aided amplification (RAA) assay for the detection of Schistosoma japonicum infections in Oncomelania hupensis snails. METHODS A group test was employed. Fifty Oncomelania snails were collected as a detection sample. The detection samples without infected snails were designated as negative specimens, while the detection samples that contained different numbers of infected snails were designated as positive specimens. A total of 10 negative specimens, 10 positive specimens containing 1 infected snail, 20 positive specimens containing 2 infected snails and 10 positive specimens containing 3 infected snails were assigned. Following random grouping, 40 specimens were subject to the florescent RAA assay using a blind method. The miradium shedding method served as a gold standard, and the sensitivity, specificity, Youden's index and coincidence rate of the florescent RAA assay were estimated. In addition, 20 samples consisted of 5 negative specimens and 15 positive specimens with 1, 2 and 3 infected snails respectively were grouped randomly. The same specimens were detected using the crushing method and fluorescent RAA assay with the blind method in a paired-design manner. Then, the test results were compared and analyzed. RESULTS Florescent RAA assay detected 29 positives in the 30 specimens containing different numbers of infected snails, with a sensitivity of 96.67%, and 8 negatives in the 10 detection specimens without infected snails, with a specificity of 80.00%, showing a Youden's index of 0.77. The coincidence rate was 100% among 10 repeated assays for a detection specimen. In addition, there was no significant difference in the detection of infected snails between the florescent RAA assay and the crushing method (χ2 = 0, P > 0.05), and the actual coincidence rates of the florescent RAA assay and crushing method were 95.00% (19/20) and 90.00% (18/20) with the real results, respectively. CONCLUSION Fluorescent RAA assay has a favorable efficiency for the detection of S. japonicum infections in Oncomelania snails, which shows a potential in screening of S. japonicum-infected Oncomelania snails.

Abstract
Objective: To analyze the expression of mismatch repair (MMR) protein and the EB virus infection in gastric adenocarcinoma, and to examine the association of MMR expression and EB virus infection with clinicopathological parameters. Methods: A case-control study was performed. Clinicopathological data of patients who was pathologically diagnosed as gastric adenocarcinoma, received radical gastrectomy and had complete clinicopathological data from August 2017 to April 2020 in Tianjin Medical University Cancer Institute and Hospital were retrospectively collected and analyzed. The immunohistochemistry (IHC) of MMR proteins and in situ hybridization (ISH) of Epstein-Barr virus encoded RNA (EBER) were reviewed. The associations of MMR and EBER results with clinicopathological parameters were analyzed. The main observations of the study were MMR and EBER expression, and association of MMR and EBER results with clinicopathological parameters. Results: Eight hundred and eighty-six patients were enrolled, including 98 patients who received preoperative neoadjuvant chemoradiotherapy. Of 886 patients, 613 (69.2%) were males and the median age was 60 (22-83) years; 831 (93.8%) were mismatch repair proficiency (pMMR), and 55 (6.2%) were mismatch repair deficiency (dMMR). In dMMR group, 47 cases (85.5%) had the deficiency of both MLH1 and PMS2, 1 case (1.8%) had the deficiency of both MSH2 and MSH6, 4 cases (7.3%) had the deficiency only in PMS2, 2 cases (3.6%) had the deficiency only in MSH6, and 1 case (1.8%) had the deficiency only in MSH2. The deficiency rates of PMS2, MLH1, MSH6 and MSH2 were 5.8% (51/886), 5.3% (47/886), 0.3% (3/886) and 0.2% (2/886), respectively. Among the 871 cases with EBER results, 4.9% (43/871) were positive EBER. Univariate analysis showed that dMMR was more frequently detected in female patients (χ(2)=10.962, P=0.001), cancer locating in the antrum (χ(2)=9.336,P=0.020), Lauren intestinal type (χ(2)=9.718, P=0.018), stage T3 (χ(2)=25.866, P<0.001) and TNM stage II (χ(2)=15.470, P=0.002). The ratio of dMMR was not significantly associated with age, tumor differentiation, histological type, lymph node metastasis, distant metastasis or Her-2 immunohistochemical score (all P>0.05). Compared with negative EBER, positive EBER was more frequent in male patients (χ(2)=9.701, P=0.002), cancer locating in gastric fundus and corpus (χ(2)=17.964, P<0.001), gastric cancer with lymphoid stroma (χ(2)=744.073, P<0.001) and poorly differentiated cancer (χ(2)=13.739, P=0.010). Positive EBER was not significantly associated with age, depth of invasion, lymph node metastasis, distant metastasis, TNM stage or Her-2 immunohistochemical score (all P>0.05). In addition, all dMMR cases were EBER negative, and all cases of positive EBER were pMMR. Conclusions: The positive EB virus status is mutually exclusive with dMMR, indicating that different molecular subtypes of gastric adenocarcinoma are involved in different molecular pathways in tumorigenesis and progression. The overlapping of dMMR or positive EBER status and positive Her-2 expression is found in some cases of gastric adenocarcinoma. Patients with gastric adenocarcinoma after radical surgery should be tested for MMR status if they are female, the tumor locates in gastric antrum, the TNM staging is stage II or T3, or if the Lauren classification is intestinal type. And if patients are male, the tumor locates in the gastric fundus and corpus, the cancer is lymphoid stroma, or poor differentiated, the expression of EBER should be detected. Results of our study may provide evidence for further decision-making of clinical treatment.

Objective
To explore the association of abdominal obesity with long-term prognosis in patients with a pacemaker.
Methods
Patients in the Summit study were enrolled and divided into groups according to baseline waist circumference: with obesity, normal, and lean. Regular follow-up was performed. The primary endpoint was all-cause mortality, and the secondary endpoint was cardiac death.
Results
In total, 492 patients were included in the analysis. The average baseline waist circumference was 84.2 ± 12.7 cm, and abdominal obesity was observed in 37.6% of patients. During a mean follow-up of 67.2 ± 17.5 months,71 all-cause mortality (14.40%) and 24 cardiac death (4.87%) events occurred. All-cause mortality was associated with higher waist circumference (87.6 versus 83.6 cm, P = 0.014), but not body mass index (23.6 versus 23.5, P= 0.930). Multivariate Cox analysis showed compared with patients with abdominal obesity, lean patients had a significant survival benefit in both all-cause mortality (HR 0.188, 95%CI 0.070-0.505, P = 0.001) and cardiac death (HR 0.097, 95% CI 0.012-0.792, P = 0.029).
Conclusions
Waist circumference was associated with long-term all-cause mortality and cardiac death. Baseline waist circumference less than 80 cm for men and less than 75 cm for women had a significant survival benefit.

Abstract
Adiponectin is essential for the regulation of tissue substrate utilization and systemic insulin sensitivity. Clinical studies have suggested a positive association of circulating adiponectin with healthspan and lifespan. However, the direct effects of adiponectin on promoting healthspan and lifespan remain unexplored. Here, we are using an adiponectin null mouse and a transgenic adiponectin overexpression model. We directly assessed the effects of circulating adiponectin on the aging process and found that adiponectin null mice display exacerbated age-related glucose and lipid metabolism disorders. Moreover, adiponectin null mice have a significantly shortened lifespan on both chow and high-fat diet. In contrast, a transgenic mouse model with elevated circulating adiponectin levels has a dramatically improved systemic insulin sensitivity, reduced age-related tissue inflammation and fibrosis, and a prolonged healthspan and median lifespan. These results support a role of adiponectin as an essential regulator for healthspan and lifespan.

Abstract
OBJECTIVE: To establish the diagnostic nomogram for tuberculous pleurisy (TP) based on TB-interferon-gamma release assays (TB-IGRA), as well as clinical and peripheral blood characteristics.MATERIAL AND METHODS: Patients who underwent TB-IGRA tests during hospitalisation and were finally diagnosed, were retrospectively and continuously enrolled. TP was divided into confirmed TP (cTP) and presumptive TP (pTP), and corresponding diagnostic nomograms were established.RESULTS: A total of 1283 patients were enrolled (median age 49 years, range 14-96; males: 63.1%). The area under the curve (AUC) of TB-IGRA was 0.81 (95%CI 0.77-0.84) for cTP (n = 272) and 0.74 (95%CI 0.71-0.78) for pTP (n = 644). The false-positive and negative rates of TB-IGRA among non-TP and cTP were respectively 32.4% and 16.8%. Based on LASSO analysis, we then selected respectively 12 and 10 predictors from clinical and peripheral blood characteristics to establish cTP and pTP nomograms (TB-IGRA was selected). The cTP and pTP nomograms had an AUC of 0.93 (95%CI 0.90-0.95) and 0.92 (95%CI 0.90-0.94) in the training group, and 0.91 (95%CI 0.87-0.96) and 0.93 (95%CI 0.89-0.96) in the validation group, respectively, which were superior to TB-IGRA test alone.CONCLUSION: Novel predictive nomograms with less invasiveness were provided based on TB-IGRA test to assist differential diagnosis of TP and non-TP patients.

Abstract
Objective: To systematically evaluate the clinical effect of anodized implants and sandblasted, large-grit, acid-etched (SLA) implants in the recent 10 years, so as to provide a reference for the selection and evaluation of implants. Methods: The data from Pubmed, Cochrane Library, Embase, CNKI, and Wanfang Data database from January 2010 to April 2020 were searched, to find clinical studies on anodized and SLA implants. According to the inclusion and exclusion criteria, literature was strictly screened, and data was extracted. Included studies were evaluated by using the methodological index for non-randomized studies (MINORS) and were analyzed by Stata14.0. The outcome of interest was cumulative survival rate (CSR) and marginal bone loss (MBL). Heterogeneity and publication bias among included literature was evaluated comprehensively. Results: A total of 22 articles, including 6 276 anodized implants, were collected for the analysis of anodized implants. Meta-analysis of proportions showed that anodized implants CSR were 98% (95%CI: 97%-98%, P<0.05) in total, at 5 years were 98% (95%CI: 98%-99%, P<0.05), and at 10 years were 97% (95%CI: 96%-98%, P<0.05). MBL change was 1.02 mm (95%CI: 0.69-1.34, P<0.05) in total. A total of 17 articles, including 4 567 SLA implants, were collected for the analysis of SLA implants. Meta-analysis of proportions showed that SLA implants CSR were 99% (95%CI: 98%-100%, P<0.05) in total, 99% at 5 years (95%CI: 98%-100%, P<0.05), and 99% at 10 years (95%CI: 97%-100%, P<0.05). MBL change was 0.69 mm (95%CI: 0.44-0.95, P<0.05) in total. The results of the above two studies were tested for bias (P>0.05), indicating no significant publication bias. Conclusions: Meta-analysis suggested that SLA implants have higher CSR and lower MBL than anodized implants.

Abstract
BACKGROUND Carbapenemase-producing organisms (CPO) have been largely responsible for the extensive spread of carbapenem resistance, and their prevalence is increasing in many parts of the world. AIM To evaluate clinical and molecular epidemiology and mortality associated with CPO among patients. METHODS All CPO from clinical and long-term healthcare surveillance cultures across Scotland in 2003-2017 were reviewed retrospectively. Polymerase chain reaction was used to detect genes coding for carbapenemases. A generalized linear mixed model was used to identify risk factors for mortality. FINDINGS In total, 290 individuals with CPO were identified. The overall incidence increased over time (P<0.001) from 0.02 to 1.38 per 100,000 population between 2003 and 2017. A total of 243 distinct CPO isolates were obtained from 269 isolations in 214 individuals with available metadata. The majority of the isolates were Enterobacterales (206/243, 84.8%), and Klebsiella pneumoniae (65/206, 31.6%) and Enterobacter cloacae (52/206, 25.2%) were the most common species. VIM (75/243, 30.9%) and NDM (56/243, 23.0%) were the most common carbapenemases. The crude 30-day mortality rate was 11.8% (25/211), while the case fatality rate was 5.7% (12/211). Age >60 years [adjusted odds ratio (aOR) 3.36, 95% confidence interval (CI) 1.06-10.63; P=0.033], presence of non-fermenters (aOR 4.88, 95% CI 1.64-14.47; P=0.005), and systemic infection or organ failure (aOR 4.21, 95% CI 1.38-12.81; P=0.032) were independently associated with 30-day mortality. CONCLUSION The incidence of CPO in Scotland is low but increasing. Awareness is required that inpatients aged >60 years, patients with systemic infection or organ failure, and patients presenting with non-fermenters are at higher risk of death from CPO.

Abstract
Abstract
Purpose: Early age at breast development (thelarche) has been associated with increased breast cancer risk. Average age at thelarche has declined over time, but there are few established risk factors for early thelarche. We examined associations between pre- and postnatal exposures and age at thelarche in a U.S. cohort of women born between 1928 and 1974. Methods: Breast cancer-free women ages 35–74 years who had a sister diagnosed with breast cancer were enrolled in the Sister Study from 2003–2009 (N = 50,884). At enrollment, participants reported their age at thelarche, which we categorized as early (≤10 years), average (11–13 years), and late (≥14 years), as well as information on early-life exposures. We estimated odds ratios (ORs) and 95% confidence intervals (CIs) for early and late thelarche relative to average age at thelarche using polytomous logistic regression for each early-life exposure, adjusted for birth cohort, race/ethnicity and family income level in childhood. We examined modification by birth cohort, race/ethnicity, family income, relative weight at age 10, and extent of breast cancer family history through stratification. Results: Early thelarche was more common in recent birth cohorts and among non-Hispanic Black and Hispanic women. Early thelarche (≤10 years) was associated with multiple prenatal exposures: gestational hypertensive disorder (OR = 1.25, 95% CI, 1.09–1.43), maternal diethylstilbestrol (DES) use (OR = 1.23, 95% CI, 1.04–1.45), maternal smoking during pregnancy (OR = 1.20, 95% CI, 1.13–1.27), and young maternal age (OR 1.30, 95% CI, 1.16–1.47 for <20 vs 25–29 years). Being firstborn was also associated with early thelarche (OR = 1.25, 95% CI, 1.17–1.33). Low birthweight (<2500 vs 2500–3999g) was suggestively associated with both early (OR = 1.06, 95% CI, 0.96–1.17) and late (OR = 1.15, 95% CI, 1.05–1.25) thelarche, as was use of soy formula in infancy (Early: OR = 1.10, 95% CI, 0.93–1.30; Late: OR = 1.07, 95% CI, 0.92–1.25). Patterns were generally similar across strata of modifiers of interest. Conclusion: Associations between pre- and postnatal exposures and age at thelarche suggest that the early-life environment may influence breast development and therefore may also affect breast cancer risk by altering the timing of pubertal breast development.

Antibiotics in marine aquaculture farms surrounding Laizhou Bay, Bohai Sea: Distribution characteristics considering various culture modes and organism species. THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 760:143863.

Abstract
This study mainly investigated the distribution characteristics and risk assessment of 14 antibiotics in typical marine aquaculture farms surrounding the Bohai Sea. The effects of various culture modes (outdoor pond culture, recirculating water culture, greenhouse pond culture, raft culture, cage culture and bottom sowing culture), and diverse cultured organism species such as fish (grouper, bass, pike and turbot), mollusk (oyster, scallop, conch and mussel) and sea cucumber on the distribution of antibiotics in different mariculture pond matrices (seawater, sediment/biofilm and organism) were studied. In addition, antibiotic pollution levels in various matrices (water, sediment, organism and feed) from different mariculture areas surrounding the Bohai Sea and the Yellow Sea were compared. The biofilm on the inner wall of greenhouse pond was more capable of accumulating antibiotics than the biofilm attached to the rope for raft culture and net for cage culture, and other culture sediments. The antibiotic concentration level in the culture matrices (water, sediment/biofilm and organism) was the highest under greenhouse pond culture mode, and that under the industrial recirculating water culture mode was the lowest. Antibiotic concentration in culture matrices of fish ponds was higher than that of sea cucumber ponds and mollusk ponds. The levels of antibiotics in water and sediment from marine aquaculture farms in Laizhou (Bohai Sea coast) were higher than those in Haiyang and Jimo (Yellow Sea coast). Enrofloxacin in turbot might cause considerable harm to human health, and the risk of antibiotics in other seafood could be ignored. Antibiotic ecological risks and resistance risks were generally low in water. Fluoroquinolones posed medium to high ecological risks in the natural receiving water around the mariculture farm. Trimethoprim and enrofloxacin showed relatively high antibiotic resistance risks in mariculture water and natural water, which might exert selective pressure on the bacterial community in the environment.

Abstract
OBJECTIVE Long noncoding RNAs (lncRNAs) are widely involved in various malignancies including osteosarcoma. In the current study, we aimed to illustrate the role of lncRNA plasmacytoma variant translocation 1 (PVT1) in osteosarcoma. PATIENTS AND METHODS Expression of PVT1 and microRNA-486 (miR-486) in osteosarcoma tissue specimens and cell lines were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) assays and in situ hybridizations (ISH) assay. Transwell migration/invasion assays were performed to determine the metastatic ability changes in osteosarcoma cells. Kaplan-Meier survival analysis was applied to analyze the overall survival (OS) of patients with osteosarcoma. Luciferase assays were used to evaluate the targeted binding effect between PVT1 and miR-486. RESULTS We illustrated that lncRNA plasmacytoma variant translocation 1 (PVT1) was upregulated in osteosarcoma, and it was correlated with poor prognosis of patients with osteosarcoma. Furthermore, we found that PVT1, via constructed loss of function and gain of function assays, promoted osteosarcoma cells migration and invasion. Meanwhile, we demonstrated that microRNA-486 (miR-486) was involved in PVT1-induced migration and invasion. We also uncovered that miR-486 was downregulated in osteosarcoma tissue specimens and cell lines. Functionally, we showed that upregulation of miR-486 reversed the facilitative effect of PVT1 on osteosarcoma cells migration and invasion, and vice versa. Mechanically, we illustrated that PVT1 interacted with miR-486 in a reciprocal suppressed manner. Moreover, we found that miR-486 could target to PVT1 via Luciferase assay. Lastly, we proved that PVT1 promoted osteosarcoma cells migration and invasion through miR-486 sponging. CONCLUSIONS We demonstrated that PVT1, functioning as an oncogene, promotes osteosarcoma cells metastasis via miR-486 sponging. PVT1/miR-486 axis might be a novel target in the molecular treatment of osteosarcoma.

Abstract
Abstract
Aims
The SELECTION (NCT02914522) Induction Studies evaluated the efficacy/safety of filgotinib (FIL), a preferential JAK1 inhibitor, as induction therapy for patients (pts) with moderately to severely active ulcerative colitis (UC) who were biologic-naïve but failed conventional therapy (Induction Study A) or failed prior biologics (Induction Study B).
Methods
Pts were randomized 2:2:1 to once–daily FIL 200mg, FIL 100mg or placebo (PBO). The primary (clinical remission), key secondary (Mayo Clinic Score [MCS] remission, endoscopic remission, and histologic remission), and exploratory endpoints (MCS response and endoscopic improvement) were assessed at Week 10.
Results
In both studies, baseline demographics and disease characteristics were similar across treatment groups. In Study A, 659 pts were randomized and treated. Baseline mean MCS was 8.6 and 56% had a Mayo endoscopic subscore (ES)=3. A significantly higher proportion of biologic-naïve pts on FIL 200mg achieved clinical remission vs PBO and all key secondary endpoints (Table). In Study B, 689 pts were randomized and treated. Baseline mean MCS was 9.3 and 78% had ES=3. Prior treatment failures were: anti-TNF (86%), vedolizumab (52%) and both (dual-refractory; 43%). A significantly higher proportion of biologic-experienced pts on FIL 200mg achieved clinical remission vs PBO. In Studies A and B, a greater proportion of pts on FIL 200 mg achieved an MCS response and endoscopic improvement vs PBO.
The rates of AEs, serious AEs and discontinuations due to AEs were similar across FIL and PBO groups during induction. In the PBO, FIL 100mg and FIL 200mg groups, serious infections occurred in 0.7%, 0.7% and 0.4% pts in Study A and 1.4%, 1.4% and 0.8% pts in Study B; H Zoster occurred in <1% in both groups for both cohorts.
Conclusions
SELECTION included a high proportion of dual-refractory pts, and pts with severe endoscopic disease. Both doses of FIL were well tolerated. Filgotinib 200mg was effective induction therapy for both biologic-naïve/-experienced pts with moderately to severely active UC.

Abstract
Climate change has a large influence on plant functional and phenotypic traits including plant primary and secondary metabolites. One well-established approach to investigating the variation in plant metabolites involves studying plant populations along elevation and latitude gradients. We considered how two space-for-time climate change gradients (elevation and latitude) influence carbohydrate reserves (soluble sugars, starches) and secondary metabolites (monoterpenes, diterpene resin acids) of lodgepole pine trees in western Canada. We were particularly interested in the relationship of terpenes and carbohydrates with a wide range of tree, site, and climatic factors. We found that only elevation had a strong influence on the expression of both terpenes and carbohydrates of trees. Specifically, as elevation increased, concentrations of monoterpenes and diterpenes generally increased and soluble sugars (glucose, sucrose, total sugars) decreased. In contrast, latitude had no impact on either of terpenes or carbohydrates. Furthermore, we found a positive relationship between concentrations of starch and total terpenes and diterpenes in the elevation study; whereas neither starches nor sugars were correlated to terpenes in the latitude study. Similarly, both terpenes and carbohydrates had a much greater number of significant correlations to site characteristics such as slope, basal area index, and sand basal area, in the elevational than in the latitude study. Overall, these results support the conclusion that both biotic and abiotic factors likely drive the patterns of primary and secondary metabolite profiles of lodgepole pine along geographical gradients. Also, presence of a positive relationship between terpenes and starches suggests an interaction between primary ad secondary metabolites of lodgepole pine trees.
