Abstract
Global polarization of Ξ and Ω hyperons has been measured for the first time in Au+Au collisions at sqrt[s_{NN}]=200 GeV. The measurements of the Ξ^{-} and Ξ[over ¯]^{+} hyperon polarization have been performed by two independent methods, via analysis of the angular distribution of the daughter particles in the parity violating weak decay Ξ→Λ+π, as well as by measuring the polarization of the daughter Λ hyperon, polarized via polarization transfer from its parent. The polarization, obtained by combining the results from the two methods and averaged over Ξ^{-} and Ξ[over ¯]^{+}, is measured to be ⟨P_{Ξ}⟩=0.47±0.10(stat)±0.23(syst)% for the collision centrality 20%-80%. The ⟨P_{Ξ}⟩ is found to be slightly larger than the inclusive Λ polarization and in reasonable agreement with a multiphase transport model. The ⟨P_{Ξ}⟩ is found to follow the centrality dependence of the vorticity predicted in the model, increasing toward more peripheral collisions. The global polarization of Ω, ⟨P_{Ω}⟩=1.11±0.87(stat)±1.97(syst)% was obtained by measuring the polarization of daughter Λ in the decay Ω→Λ+K, assuming the polarization transfer factor C_{ΩΛ}=1.

A novel dentin bonding scheme based on extrafibrillar demineralization combined with covalent adhesion using a dry-bonding technique. Bioact Mater 2021; 6:3557-3567. [PMID: 33842741 PMCID: PMC8022110 DOI: 10.1016/j.bioactmat.2021.03.024] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 02/26/2021] [Accepted: 03/11/2021] [Indexed: 01/21/2023] Open
Abstract
Dentin bonding is a dynamic process that involves the penetration of adhesive resin monomers into the extrafibrillar and intrafibrillar demineralized collagen matrix using a wet-bonding technique. However, adhesive resin monomers lack the capacity to infiltrate the intrafibrillar space, and the excess water that is introduced by the wet-bonding technique remains at the bonding interface. This imperfectly bonded interface is inclined to hydrolytic degradation, severely jeopardizing the longevity of bonded clinical restorations. The present study introduces a dentin bonding scheme based on a dry-bonding technique, combined with the use of extrafibrillar demineralization and a collagen-reactive monomer (CRM)-based adhesive (CBA). Selective extrafibrillar demineralization was achieved using 1-wt% high-molecular weight (MW) carboxymethyl chitosan (CMCS) within a clinically acceptable timeframe to create a less aggressive bonding substance for dentin bonding due to its selectively extrafibrillar demineralization capacity. CMCS demineralization decreased the activation of in situ collagenase, improved the shrinking resistance of demineralized collagen, and thus provided stronger and more durable bonding than traditional phosphoric acid etching. The new dentin bonding scheme that contained CMCS and CBA and used a dry-bonding technique achieved an encouraging dentin bonding strength and durability with low technical sensitivity. This bonding scheme can be used to improve the stability of the resin-dentin interface and foster the longevity of bonded clinical restorations.

Abstract
Nonmonotonic variation with collision energy (sqrt[s_{NN}]) of the moments of the net-baryon number distribution in heavy-ion collisions, related to the correlation length and the susceptibilities of the system, is suggested as a signature for the quantum chromodynamics critical point. We report the first evidence of a nonmonotonic variation in the kurtosis times variance of the net-proton number (proxy for net-baryon number) distribution as a function of sqrt[s_{NN}] with 3.1 σ significance for head-on (central) gold-on-gold (Au+Au) collisions measured solenoidal tracker at Relativistic Heavy Ion Collider. Data in noncentral Au+Au collisions and models of heavy-ion collisions without a critical point show a monotonic variation as a function of sqrt[s_{NN}].

The antibacterial effect and physical performance of pit and fissure sealants based on an antibacterial core-shell nanocomposite. J Mech Behav Biomed Mater 2021; 117:104414. [PMID: 33647728 DOI: 10.1016/j.jmbbm.2021.104414] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2020] [Revised: 02/16/2021] [Accepted: 02/17/2021] [Indexed: 10/22/2022]
Abstract
The application of pit and fissure sealants is a well-established method to prevent and treat early childhood caries. Resin-based sealants with antibacterial properties provide additional benefits for caries prevention in a cariogenic oral environment. The objective of this study was to evaluate the effect of an antibacterial core-shell AgBr/cationic polymer nanocomposite (AgBr/BHPVP) on the properties of a resin-based pit and fissure sealant. A commercialized pit and fissure sealant without fluoride, Concise (3M, ESPE, USA), was used as the parent material and negative control. Experimental antibacterial sealants were formulated by the addition of AgBr/BHPVP nanoparticles at mass fractions of 0.5, 1.0, and 1.5 wt% to the parent material. A fluoride-releasing sealant, Clinpro (3M, ESPE), was used as the positive control. Bacterial colony-forming unit (CFU) counts, metabolic activity tests, field emission-scanning electron microscopy (FE-SEM), and confocal laser scanning microscopy (CLSM) observations were used to evaluate the antibacterial properties of AgBr/BHPVP-modified sealants against Streptococcus mutans before and after five months of aging. The Vickers microhardness, degree of conversion, and microleakage level of the sealants were also investigated. According to the results of CFU counts and metabolic tests, sealants containing AgBr/BHPVP showed better contact-killing bactericidal activity against S. mutans than the two commercial sealants, irrespective of aging conditions (both P < 0.05). The AgBr/BHPVP-modified sealants also showed a significant inhibitory effect on the planktonic S. mutans around the cured sealant surfaces. In addition, the Vickers microhardness, degree of conversion, and microleakage level of the parent material were not damaged by modification with AgBr/BHPVP (P > 0.05). AgBr/BHPVP-modified pit and fissure sealant with a dual bactericidal mechanism is a promising option for the prevention of pit and fissure caries.

Abstract
OBJECTIVES The aim of this study is to investigate the impact of bariatric surgery on non-traffic accident-related fractures in patients with obesity. METHODS This retrospective cohort study was conducted using the Taiwan National Health Insurance Research Database. Patients aged 18 to 55 years with obesity diagnosis between 2003 and 2008 were enrolled and divided into two groups: non-surgical and bariatric surgery groups. Patients with endocrine bone disease and malignancy history were excluded. Healthy patients were also randomly selected from the database and assigned to the general population group. The development of fracture was the primary end point. All patients were followed until the end of 2013 or death, whichever came first. RESULTS After propensity score matching, 1322, 1322, and 4359 subjects were included in the bariatric surgery (BS), non-surgical (NS), and general population (GP) groups, respectively. Based on multivariate analysis, the risk of overall fractures is similar between the BS group (hazard ratio [HR] = 0.774, p = 0.164) and the NS group; nevertheless, the risk of overall fractures was higher in the BS group (HR = 2.210, p<0.001) than in the GP group. The BS group had a significantly lower risk of non-traffic accident-related fractures (HR = 0.542, p = 0.010) than the NS group but a higher risk of non-traffic accident-related fractures (HR = 1.693, p = 0.023) than the GP group. CONCLUSIONS Bariatric surgery may decrease the risk of non-traffic accident-related fractures; however, the risk remains higher in patients with obesity than in the general population.

Abstract
PURPOSE This study aims to determine whether bariatric surgery (BS) decreases the risk of respiratory tract infections (RTIs) in obese patients. MATERIALS AND METHODS This retrospective, population-based, matched cohort study utilized data from the Taiwan National Health Insurance Research Database. All patients 18 to 55 years of age with obesity diagnosed between 2005 and 2010 were enrolled. Patients were separated into two groups based on whether they underwent BS. Two groups were selected using 1:1 propensity score matching according to age, sex, and comorbidities. The general population was also enrolled for comparison. The primary endpoint was the incidence of RTIs, including pneumonia, influenza, and bronchitis. All patients were followed up until the end of 2013, the primary endpoint, or death. RESULTS Compared to the non-surgery group, the BS group was at significantly lower risk for RTIs (aHR 0.432, 95% CI 0.340-0.549, p < 0.001) with shorter length of hospital stay (LOH) and lower cost. Regardless of the RTI-related mortality, pneumonia, influenza, and bronchitis rates, BS did have significant protective effects on the non-surgery group. Compared to the general population, the BS group was at higher risk for RTIs (aHR 3.601, 95% CI 2.742-4.728, p < 0.001) with similar LOH and lower cost. CONCLUSION Patients with obesity who underwent BS were at significantly lower risk for RTIs than obese patients who did not undergo BS but were at higher risk for RTIs than the general population. BS may result in a long-term reduction of the RTI risk.

Abstract
INTRODUCTION Our study aims to identify that patients who received hernia repair previously did have higher risk of occurrence of newly developed inguinal hernia, named as a contralateral inguinal hernia (CIH), than patients who never received inguinal hernia surgery before. MATERIALS AND METHODS We collected data from the National Health Insurance Research Database (NHIRD) of Taiwan retrospectively. In the study cohort, 64,089 Asian male adults who underwent primary unilateral inguinal hernia repair during 2003-2008 were included using ICD-9 diagnostic and surgical codes. Another 64,089 male adults without hernia repair history were included as control group via propensity score match. RESULTS The median follow-up period is 93.53 months. After multivariate analysis, the risk of newly developed inguinal hernia in unilateral inguinal hernia (UIH) repair cohort was significantly higher (adjusted HR 6.364, 95% CI 6.012-6.737, P < 0.001) than the control group. In subgroup analysis, patients without mesh repair (adjusted HR 6.706, P < 0.001) and patients with mesh repair (adjusted HR 5.559, P < 0.001) both showed higher risk of developing newly developed inguinal hernia which needs repair. CONCLUSIONS Asian men with UIH repair history had a higher risk of developing new inguinal hernia at the contralateral site, namely CIH, than the general population. The surgeon should inform the possibility of CIH after initial herniorrhaphy, therefore, monitoring the occurrence of CIH is necessary.

Abstract
Approximately 500,000 new cases of head and neck squamous cell carcinoma (HNSCC) are reported annually. Radiation therapy is an important treatment for oral squamous cell carcinoma (OSCC). The survival rate of patients with HNSCC remained low (50%) in decades because of radiation therapy failure caused by the radioresistance of HNSCC cells. This study aimed to identify PI3K inhibitors that can enhance radiosensitivity. Results showed that pan-Phosphoinositide 3-kinases (PI3K) inhibitor BKM120 and class I α-specific PI3K inhibitor BYL719 dose-dependently reduced the growth of OSCC cells but not that of radioresistant OML1-R cells. The combination treatment of BKM120 or BYL719 with radiation showed an enhanced inhibitory effect on OSCC cells and radioresistant OML1-R cells. Furthermore, the enhanced inhibitory effect of the combination treatment was confirmed in patient-derived OSCC cells. The triple combination treatment of mTOR inhibitor AZD2014 and BKM120 or AZD2014 and BYL719 with radiation showed a significantly enhanced inhibitory effect on radioresistant OML1-R cells. These results suggest that the PI3K inhibitors are potential therapeutic agents with radiosensitivity for patients with OSCC.

Abstract
Objective: To analyze the safety and efficacy of percutaneous vertebroplasty combined with interstitial implantation (125)I of seeds (PVPI) in the treatment of thoracic vertebroplasty with posterior vertebra defect. Methods: A retrospective analysis of the clinical data of 64 patients with thoracic spine metastases admitted to Yunnan Cancer Hospital from November 2017 to May 2019 was conducted, including 32 patients with posterior vertebra defect (experimental group) and 32 cases without (control group). Forty-two vertebral bodies of 32 patients in the experimental group were treated with improved PVPI surgery, which performed with the secondary sealing method and inclined puncture needle injection bone cement rotary filling technology, to reduce leakage. The 54 vertebral bodies of 32 patients in control group underwent PVPI. The two groups of patients were followed up on the second day, one month, three months and six months after the operation, and the short-term efficacy, long-term efficacy and safety indicators of the two groups were compared. Results: All 64 patients successfully completed the surgical treatment. The visual analogue scores and Karnofsky scores of the experimental group and the control group were improved to varying degrees on the second day, 1 month, 3 months and 6 months after the operation. There was no statistically significant difference between the two groups (P>0.05). The amount of bone cement in the experimental group and control group was (2.36±0.20) ml and (2.39±0.17) ml, and the difference was not statistically significant (P=0.482). The amount of (125)I seed implantation was (30.63±0.91) and (32.56±0.68), respectively, the difference was not statistically significant (P=0.925). The partial response rates of the study group and the control group were 81.3% and 87.5%, the stable disease rates were 12.5% and 9.4%, the differences were not statistically significant (P>0.05). The median overall survival (mOS) of the study group was 13 months, and the median progression-free survival (mPFS) was 8 months. The mOS of the control group was 14 months, and the mPFS was 8 months. The differences were not statistically significant (P>0.05). In the experimental group, 6 (14.3%) vertebral bodies had cement leakage, of which 2 (4.8%) were cement leakage at posterior vertebra, 4 (9.5%) were paravertebral cement leakage. Seven (13.0%) paravertebral cement leakage occurred in the control group. There was no significant difference in bone cement leakage between the two groups (P=0.097). Bone cement leakage in both groups did not cause serious complications such as spinal cord injury and paraplegia. Conclusion: The application of PVPI in the treatment of thoracic metastatic tumor patients with posterior vertebra defect can acquire better clinical efficacy and safety through conduction of the improved intraoperative technology and paying more attention to the control of bone cement distribution and other issues.

Abstract
Objective: To retrospectively analyze the early mortality and related risk factors in adult patients with maintenance hemodialysis (MHD). Methods: Adult MHD patients from 2008 to 2018 were enrolled and divided into training data group and validation data group. In training data group, multivariate logistic regression was used to analyze the risk factors of early death within 120 days after hemodialysis and establish a prediction model. The receiver operating characteristic (ROC) curve was applied to evaluate the prediction ability of the model. Results: A total of 4 885 patients were included. The cumulative mortality within 120 days was 20.97/100 person years, and that within 365 days was 12.25/100 person years. A total of 3 603 patients in the training data group were analyzed. The following risk factors were correlated with early mortality (all P<0.05), including age at start of dialysis over 60 years old (OR=1.792), non-chronic glomerulonephritis (OR=2.214), cardio-cerebrovascular disease (OR=2.695), plasma albumin less than 35 g/L (OR=1.358), platelet count less than 120×109/L (OR=2.194), serum creatinine less than 600 μmol/L (OR=1.652), blood urea nitrogen over 30 mmol/L (OR=1.887), blood phosphorus less than 1.13 mmol/L (OR=1.783), pulse pressure over 55 mmHg(1 mmHg=0.133 kPa) (OR=1.656), low density lipoprotein less than 1.5 mmol/L (OR=1.873), and blood calcium over 2.5 mmol/L (OR=1.876). Risk prediction model was established. The other 1 282 cases in the validation data group were verified. The area under ROC curve was 0.810, with sensitivity 85.7%, and specificity 62.5%. Conclusion: The mortality rate of adult MHD patients within 120 days after dialysis is high. The established prediction model can effectively predict the risk of early death.

Bariatric surgery may provide better protection than uvulopalatopharyngoplasty against major adverse cardiovascular events in obese patients with obstructive sleep apnea. Surg Obes Relat Dis 2020; 17:780-791. [PMID: 33423961 DOI: 10.1016/j.soard.2020.11.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 11/13/2020] [Accepted: 11/20/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND The major adverse cardiovascular events (MACE) risk is unclear among Asian obese patients with obstructive sleep apnea (OSA) who undergo bariatric surgery (BS) or uvulopalatopharyngoplasty (UPPP). OBJECTIVES We aimed to evaluate differences between Asian obese patients with OSA who underwent BS or UPPP regarding MACE. SETTING The Longitudinal Health Insurance Database, a subset of the NHI Research Database (NHIRD) originated from the National Health Insurance (NHI) program in Taiwan, which comprises information from 2 million randomly sampled individuals between 2000 and 2015. METHODS Participants aged 18-55 years whose diagnoses corresponded with codes in the International Classification of Diseases, Ninth Revision, Clinical Modification for BS, UPPP, obesity, and OSA were included in this population-based, matched cohort study of Taiwan's insurance claims data gathered between 2000 and 2015. Obese patients with OSA who underwent BS or UPPP were propensity score matched; the study's outcome was MACE. RESULTS A total of 1336 patients, comprising 668 in each of the BS and UPPP cohorts, were enrolled. After a mean follow-up period of 8.51 years, 166 patients, comprising 52 in the BS cohort and 114 in the UPPP cohort, experienced MACE. The adjusted hazard ratio (aHR) for MACE was .592 (95% confidence interval [CI] = .324-.789; P < .001). The BS cohort had lower risks of stroke (aHR = .663; 95% CI = .312-.890; P < .001), myocardial infarction (aHR = .116; 95% CI = .052-.135; P < .001), and mortality (aHR = .779; 95% CI = .423-.948; P = .001) than the UPPP cohort. CONCLUSION BS may provide greater protection against MACE than UPPP in Asian obese patients with OSA. Additional mechanistic research is needed to clarify differences between BS and UPPP in these patients.

Abstract
BACKGROUND/AIM Colorectal cancer (CRC) is one of the most common malignant tumors in the world. This study aimed to investigate the anticancer effect of the combination treatment of Ribociclib (LEE011) and 5-Fluorouracil (5-FU) on CRC cells. MATERIALS AND METHODS HT-29 and SW480 cells were treated with LEE011, 5-FU, or the combination of LEE011 and 5-FU. Cell viability and cycle were investigated through 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium assay and flow cytometry. The expression of cell cycle-related proteins was determined through western blot. RESULTS The combined treatment of LEE011 with 5-FU synergistically reduced cell viability in HT-29 and SW480 cells. Specifically, it induced cell cycle arrest at the G1 phase, down-regulated the phosphorylation of retinoblastoma protein and the expression of p53. CONCLUSION LEE011 exhibited potential as an effective therapeutic inhibitor for the combination treatment of CRC patients.

Abstract
RATIONALE Intussusception is defined as the invagination or telescoping of a proximal portion of the intestine into the distal portion of the intestine. Intussusception can occur at any age but is more common among children. Most cases of intussusception in adults have a pathological lead point. Inflammatory fibroid polyp (IFP) is a rare benign tumor-like lesion arising from the submucosa of the gastrointestinal tract that can cause intussusception in adults. Here, we report a case of adult intussusception due to IFP. We also present a literature review of 31 reports including 34 cases between 2012 and December 2019, which shows a mean age of 45.4 ± 14.2 years and female dominance (23/34) of intussusception due to IFP. PATIENT CONCERNS A 47-year-old man presented with a half-day history of epigastric abdominal pain. Physical examination revealed distension and tenderness of the upper abdomen. Computed tomography (CT) of the abdomen and pelvis demonstrated intussusception of the jejunum along with a suspicious jejunal mass associated with mesenteric lymphadenopathies. DIAGNOSIS Intussusception of the jejunum along with a suspicious jejunal mass, and histopathological examination of the resected specimen showed IFP. INTERVENTIONS The patient underwent emergency laparotomy. The intussusception was resected without attempts for reduction. OUTCOMES The postoperative period was uneventful, and the patient was discharged on the fourth postoperative day. LESSONS Intussusception in adults is rare, especially that secondary to IFP. The most commonly used diagnostic tool for adult intussusception is abdominal CT, and the optimal management is resection of the involved bowel segment without reduction if malignancy cannot be ruled out.

Abstract
Blastocystis is a unicellular, anaerobic, intestinal protozoan that infects humans and a variety of animals, which is widely prevalent across the world. Blastocystis infections have been detected in healthy populations, children, students, outpatients and inpatients, as well as diarrhea patients in China. High prevalence of Blastocystis infections has been reported in immunocompromised patients, and relatively high prevalence was seen in individuals living in Guangxi and Yunnan regions. Based on the small subunit ribosomal RNA (SSU rRNA) gene sequence, a total of 17 subtypes (ST1 to ST17) of Blastocystis have been characterized until now, among which ST1 to ST9 and ST12 infect humans and animals, and ST10 to ST17 only infect animals. In China, ST1 to ST3 are predominant human Blastocystis subtypes, and ST1/ST3, ST1/ST2 and ST2/ST3 mixed infections have been also identified. This review mainly describes the epidemiology and genotypes of Blastocystis in humans and animals in China.

Abstract
Objective: To study the strategy of endovascular treatment for patients with the risks of internal carotid artery (ICA) rupture and bleeding during the treatment of nasopharyngeal carcinoma (NPC) based on American Society of Intervention and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) grade of collateral circulation. Methods: A total of 56 patients (45 males and 11 females, aged from 28 to 76 years old) diagnosed with nasopharyngeal carcinoma and admitted to the Department of Neurosurgery, the Third Affiliated Hospital of Southern Medical University from July 2018 to January 2020 were retrospectively analyzed. There were 15 cases of ASITN/SIR grade 4, 24 cases of ASITN/SIR grade 3, 5 cases of ASITN/SIR grade 2, 5 cases of ASITN/SIR grade 1, and 7 cases of ASITN/SIR grade 0. The events of stroke and death were analyzed statistically. Results: ALL patients with ASITN/SIR grade 4 or 3 and some of patients with ASITN/SIR grades 2-0 passed balloon occlusion test and electrophysiological monitoring. ICA pseudoaneurysm was found in 35 patients, and one-stage ICA embolization was performed in 29 patients after evaluation. Among them, 8 cases of ASITN/SIR grade 4 and 10 cases of ASITN/SIR grade 3 with obvious posterior circulation compensation obtained successful one-stage ICA embolization without cerebral ischemia; cerebral ischemic events occurred in 5 (55.6%) of 9 patients with ASITN/SIR grade 3 and in 1(50.0%) of 2 patients with ASITN/SIR grade 2. The total incidence of ischemic events was 20.7% (6/29) and 1 case was disabled (1/29, 3.4%). Among patients with ASITN/SIR 3, there were statistically significant differences in stroke event rate between patients with obvious posterior circulation compensation and patients with slight or without posterior circulation compensation (0/10 vs. 5/9, χ(2)=4.95, P=0.026). Follow-up time was 10.1±7.8 months, and 46 patients were survival (46/56, 82.1%) and 10 patients died (10/56, 17.9%) with a mean survival time of 2.6±1.4 months. Conclusions: For NPC patients with ICA invasion, ASITN/SIR based on DSA can simplify the assessment process of cerebral blood flow compensation. ICA can be embolized directly in patients with ASITN/SIR 4 or 3 with obvious posterior communicating compensation.

Abstract
OBJECTIVE To assess the associations of different monitoring metrics for short-term exposure to ambient ozone (O3) with pulmonary function and airway inflammation in healthy young adults. METHODS A total of 97 healthy young college students were recruited and followed in a panel study conducted from December 2017 to June 2018. Each participant underwent 3 follow-up visits, and lung function and fractional exhaled nitric oxide (FeNO) were measured at each visit. Ambient air pollutant concentrations were obtained from the environment monitoring station of Beijing closest to the participant residences, and meteorological data were collected from China Meteorological Data Service Center. Linear mixed-effect models were applied to assess the associations between different monitoring metrics for ambient O3 short-term exposure with pulmonary function or airway inflammation in the healthy young adults. RESULTS During the study period, the P50 (P25, P75) values for ambient O3 concentration expressed as daily 1-hour maximum (O3-1 h max), daily maximum 8-hour average (O3-8 h max) and 24-hour average (O3-24 h avg) were 102.5 (76.8, 163.0) μg/m3, 91.1 (68.3, 154.3) μg/m3 and 61.6 (36.9, 81.7) μg/m3, respectively. The different monitoring metrics for short-term exposure to ambient O3 were significantly associated with reduced forced expiratory volume in the first second (FEV1) and increased FeNO. An interquartile range (IQR) increase in 6-d moving average of O3-1 h max (IQR=71.5 μg/m3) was associated with a 6.2% (95%CI: -11.8%, -0.5%) decrease in FEV1 and a 63.3% (95%CI: 13.8%, 134.3%) increase in FeNO. An IQR increase in 7-d moving average of O3-8 h max (IQR=62.0 μg/m3) was associated with a 6.2% (95%CI: -11.6%, -0.7%) decrease in FEV1and a 75.5% (95%CI: 19.3%, 158.0%) increase in FeNO. An IQR increase in 5-d moving average of O3-24 h avg (IQR=32.9 μg/m3) was associated with a 3.7% (95%CI: -7.1%, -0.2%) decrease in FEV1and a 25.3% (95%CI: 3.6%, 51.6%) increase in FeNO. There was no significant association between the three monitoring metrics for O3 exposure and peak expiratory flow (PEF). CONCLUSION Short-term exposure to ambient O3 was associated with decreased lung function and increased airway inflammation among the healthy young adults, and daily 1-hour maximum was more sensitively to the respiratory effects of O3.

Abstract
We report on the first measurement of the charmed baryon Λ_{c}^{±} production at midrapidity (|y|<1) in Au+Au collisions at sqrt[s_{NN}]=200 GeV collected by the STAR experiment at the Relativistic Heavy Ion Collider. The Λ_{c}/D^{0} [denoting (Λ_{c}^{+}+Λ_{c}^{-})/(D^{0}+D[over ¯]^{0})] yield ratio is measured to be 1.08±0.16 (stat)±0.26 (sys) in the 0%-20% most central Au+Au collisions for the transverse momentum (p_{T}) range 3<p_{T}<6 GeV/c. This is significantly larger than the pythia model calculations for p+p collisions. The measured Λ_{c}/D^{0} ratio, as a function of p_{T} and collision centrality, is comparable to the baryon-to-meson ratios for light and strange hadrons in Au+Au collisions. Model calculations including coalescence hadronization for charmed baryon and meson formation reproduce the features of our measured Λ_{c}/D^{0} ratio.

Abstract
This study evaluated the use of a new collagen-reactive monomer (CRM), isocyanate-terminated urethane methacrylate precursor, which has covalent affinity to dental collagen, in the formation of dentin-resin bonds and compared it with 2 other dental adhesives. Dentin specimens were bonded with either the CRM-based adhesive (CBA), One-Step (OS; Bisco, Inc.), or a negative adhesive (NA) control and subjected to 24-h storage in water, thermocycling to simulate 1-y clinical function, or a matrix metalloproteinase-mediated aging process. We tested the microtensile bond strength (µTBS), characterized the bonding interface with an atomic force microscope, conducted micro-Raman analysis, and performed leakage tests and in situ zymography. CBA and OS exhibited comparable bonding strength after 24 h (P > 0.05); however, there was a sharp decrease in µTBS after aging for all except CBA (P < 0.001). Raman spectra results indicated increased collagen crosslinking and chemical reaction between the adhesive and collagen in the CBA group. CBA achieved high-quality hybridization with collagen, improving mechanical properties and integrity, and decreased the enzyme-mediated degradation of the bonding interface by inhibiting collagenolytic activity. With the promising bonding durability of coapplied CBA, CRM may be the first dental adhesive to provide strong and long-lasting resin-dental collagen bonding without the additional conditioning step. The use of CBA results in high-quality hybrid layers that protect the resin-dentin interface from harmful biological and chemical activities commonly occurring in the oral environment.

Abstract
We report constraints on the dark photon effective kinetic mixing parameter (κ) with data taken from two p-type point-contact germanium detectors of the CDEX-10 experiment at the China Jinping Underground Laboratory. The 90% confidence level upper limits on κ of solar dark photon from 205.4 kg-day exposure are derived, probing new parameter space with masses (m_{V}) from 10 to 300 eV/c^{2} in direct detection experiments. Considering dark photon as the cosmological dark matter, limits at 90% confidence level with m_{V} from 0.1 to 4.0 keV/c^{2} are set from 449.6 kg-day data, with a minimum of κ=1.3×10^{-15} at m_{V}=200 eV/c^{2}.

Abstract
Prostate cancer (Pca) is the second frequent malignancy in men. Long noncoding RNAs (lncRNAs) have been reported to play essential roles in the progression of cancers, including Pca. LncRNA colorectal neoplasia differentially expressed (CRNDE) has been found to affect tumorigenesis in many cancers. However, the exact role and mechanism of CRNDE in Pca remain poorly understood. 64 Pca patients were recruited in this study. PC3 and 22RV1 cells were used in vitro experiments. The expressions of CRNDE, microRNA-101 (miR-101), and Ras-related protein 1A (Rap1A) were detected in vivo and in vitro by quantitative real-time polymerase chain reaction and western blot, respectively. Cell proliferation, apoptosis, migration, and invasion were investigated through cell counting kit-8, flow cytometry, and Transwell assays, respectively. The interaction between miR-101 and CRNDE or Rap1A was explored by bioinformatics analysis and luciferase reporter assay. High expression of CRNDE was shown in Pca tissues and cells and predicted poor outcomes of patients. Overexpression of CRNDE promoted cell proliferation, migration, and invasion but decreased apoptosis in Pca cells, while its knockdown showed an opposite effect. CRNDE was a decoy of miR-101 and its effect on Pca progression was reversed by miR-101. Rap1A was identified as a target of miR-101 and it attenuated the effect of miR-101 on Pca development. Moreover, the Rap1A protein level was positively regulated by CRNDE, which was weakened by miR-101. CRNDE contributed to cell proliferation, migration, and invasion by regulating the miR-101/Rap1A axis in Pca, providing a novel strategy for Pca treatment.

Abstract
Objective: To summarize the clinical features of immunodeficiency diseases with interstitial lung disease (ILD) as major clinical manifestations and to improve understanding etiology of ILD. Methods: The clinical features and clinical clues for diagnosis of six cases with immunodeficiency presented with ILD in Shenzhen Children's Hospital from January 2014 to December 2016 were retrospectively analyzed. Results: The patients' age ranged from 3 months to 5 years and 9 months, 5 cases were male. All cases had cough and tachypnea, 3 cases had lung infection and respiratory failure, 2 cases had chronic hypoxia and one had clubbing. Three cases had skin rashes; 5 cases had failure to thrive. Chest CT scan showed diffuse ground glass opacity in all the 6 cases, and 2 cases had cystic changes and one had "crazy-paving" pattern. Five patients were suspected to have surfactant dysfunction and genetic testing was performed before diagnosis of immunodeficiency, of which the results were negative. With human immunodeficiency virus antibody test or immunologic laboratory testing and/or immune genetic panel, acquired immune deficiency syndrome was confirmed in one case, hyper-IgM syndrome was confirmed in two cases and hyper-IgE syndrome in one case, Wiskott-Aldrich syndrome in one and STAT3 gain of function genetic mutation in another. All cases had clinical clues indicative of underlying immunocompromise. Conclusions: The clinical features of immunodeficiency diseases with ILD are cough, tachypnea or hypoxia, respiratory failure with infection, diffuse ground glass opacity in Chest CT imaging. With thorough medical history and immunology screening, there would be clinical clues indicative of underlying immunocompromise. Screening for immunodeficiency disease should be emphasized in the differential diagnosis of ILD, otherwise it may lead to misdiagnosis or unnecessary testing.

Comparative efficacy and safety of lock solutions for the prevention of catheter-related complications including infectious and bleeding events in adult haemodialysis patients: a systematic review and network meta-analysis. Clin Microbiol Infect 2019; 26:545-552. [PMID: 31857208 DOI: 10.1016/j.cmi.2019.12.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Revised: 11/28/2019] [Accepted: 12/08/2019] [Indexed: 10/25/2022]
Abstract
BACKGROUND Central venous catheters are used extensively as temporary or permanent vascular access for haemodialysis patients. Catheter-related bloodstream infections are the main complication of central venous catheters and increase morbidity and mortality in haemodialysis patients. OBJECTIVES The aim was to assess the most appropriate lock solution for central venous catheters to prevent catheter-related bloodstream infections and other complications. DATA SOURCES Medline, Embase and the Cochrane Central Register of Controlled Trials from the date of their inception to August 2018 were used as data sources. The reference lists of eligible studies and relevant reviews were also checked. STUDY ELIGIBILITY CRITERIA AND PARTICIPANTS Randomized controlled trials (RCTs) comparing different lock solutions for the prevention of central venous catheter-related infectious and bleeding complications for adult dialysis patients were included. INTERVENTIONS Interventions were lock solutions for haemodialysis catheters. METHODS The primary outcomes were catheter-related bloodstream infections and bleeding events. The secondary outcomes were catheter malfunction, exit-site infection, and all-cause mortality. We estimated summary risk ratios (RRs) using pairwise and network meta-analysis. We assessed the risk of bias of individual studies with the Cochrane risk of bias tool. RESULTS Forty-nine trials (7020 patients) were included for this study. Compared with heparin 5000 U/mL, antibiotic locks (antibiotics with trisodium citrate (TSC), ethylenediamine tetraacetic acid (EDTA), heparin 5000 U/mL, low-dose heparin or urokinase) and ethanol locks were more effective in preventing catheter-related bloodstream infections. Antimicrobial agents plus low-dose heparin (500-2500 U/mL), TSC and low-dose heparin locks had lower risk of bleeding events than heparin 5000 U/mL. None of the lock solutions reduced rates of catheter malfunction and all-cause mortality compared with heparin 5000 U/mL. In summary, antibiotics plus low-dose heparin was ranked as the best lock solution. The overall results were not materially changed in sensitivity analyses. CONCLUSIONS Taking into account both efficacy and safety, antibiotics plus low-dose heparin (500-2500 U/mL) may be the preferred lock solution.

Abstract
We present results on light weakly interacting massive particle (WIMP) searches with annual modulation (AM) analysis on data from a 1-kg mass p-type point-contact germanium detector of the CDEX-1B experiment at the China Jinping Underground Laboratory. Datasets with a total live time of 3.2 yr within a 4.2-yr span are analyzed with analysis threshold of 250 eVee. Limits on WIMP-nucleus (χ-N) spin-independent cross sections as function of WIMP mass (m_{χ}) at 90% confidence level (C.L.) are derived using the dark matter halo model. Within the context of the standard halo model, the 90% C.L. allowed regions implied by the DAMA/LIBRA and CoGeNT AM-based analysis are excluded at >99.99% and 98% C.L., respectively. These results correspond to the best sensitivity at m_{χ}<6 GeV/c^{2} among WIMP AM measurements to date.
