Congenital bilio-bronchial fistula in an adult: a review of literature and video demonstration of laparoscopic fistula tract excision. JOURNAL OF MINIMALLY INVASIVE SURGERY 2024; 27:1-11. [PMID: 38494180 PMCID: PMC10961235 DOI: 10.7602/jmis.2024.27.1.1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 10/25/2023] [Accepted: 11/10/2023] [Indexed: 03/19/2024]
Abstract
This article presents a review of the literature on congenital bilio-bronchial fistula (BBF), a rare anomaly characterized by abnormal communication between the bile duct and respiratory tract. Congenital BBF often presents with bilioptysis in early neonates and infants; however, patients with no overt symptoms may occasionally present in adulthood. Our literature search in Medline from 1850 to 2023 revealed 42 reported cases of congenital BBF, primarily managed with thoracotomy and excision of the fistula tract. About one-third of these cases required multiple surgeries due to associated biliary anomalies. The review underscores the importance of diagnostic imaging, including bronchoscopy, in identifying and delineating the extent of the fistula. It also highlights the evolving surgical management, with recent cases showing the efficacy of minimally invasive approaches such as laparoscopy and thoracoscopy. In addition to the literature review, we report a young female patient with a history of recurrent respiratory infections presenting with bilioptysis and extensive left lung damage. Initial management included bronchoscopy-guided glue instillation, left thoracotomy, and pneumonectomy. Following the recurrence of symptoms, the patient was successfully treated with laparoscopic excision of the fistula tract. In recent times, minimally invasive approaches such as laparoscopy and thoracoscopy, with excision of the fistula tract are gaining popularity and have shown good results. We suggest biliary communication being the high-pressure end, tackling it transabdominal may prevent recurrent problems.

Abstract
Objective: To explore the efficacy of chemotherapy re-challenge in the third-line setting for patients with metastatic colorectal cancer (mCRC) in the real world. Methods: The clinicopathological data, treatment information, recent treatment efficacy, adverse events and survival data of mCRC patients who had disease progression after treatment with oxaliplatin-based and/or irinotecan-based chemotherapy and received third-line chemotherapy re-challenge from January 2013 to December 2020 at Tianjin Medical University Cancer Institute and Hospital were retrospectively collected. Survival curves were plotted with the Kaplan-Meier method, and the Cox proportional hazard model was used to analyze the prognostic factors. Results: A total of 95 mCRC patients were included. Among them, 32 patients (33.7%) received chemotherapy alone and 63 patients (66.3%) received chemotherapy combined with targeted drugs. Eighty-three patients were treated with dual-drug chemotherapy (87.4%), including oxaliplatin re-challenge in 35 patients and irinotecan re-challenge in 48 patients. The remaining 12 patients were treated with triplet chemotherapy regimens (12.6%). Among them, as 5 patients had sequential application of oxaliplatin and irinotecan in front-line treatments, their third-line therapy re-challenged both oxaliplatin and irinotecan; 7 patients only had oxaliplatin prescription before, and these patients re-challenged oxaliplatin in the third-line treatment. The overall response rate (ORR) and disease control rate (DCR) reached 8.6% (8/93) and 61.3% (57/93), respectively. The median progression free survival (mPFS) and median overall survival (mOS) were 4.9 months and 13.0 months, respectively. The most common adverse events were leukopenia (34.7%) and neutropenia (34.7%), followed by gastrointestinal adverse reactions such as nausea (32.6%) and vomiting (31.6%). Grade 3-4 adverse events were mostly hematological toxicity. Cox multivariate analysis showed that gender (HR=1.609, 95% CI: 1.016-2.548) and the PFS of front-line treatments (HR=0.598, 95% CI: 0.378-0.947) were independent prognostic factors. Conclusion: The results suggested that it is safe and effective for mCRC patients to choose third-line chemotherapy re-challenge, especially for patients with a PFS of more than one year in front-line treatments.

Abstract
A sudden drop of air-fluid level in the pneumonectomy space in the absence of a bronchopleural fistula and pleural infection is termed benign emptying of the pneumonectomy space (BEPS). We report a 28-year-old female patient who presented to a tertiary care referral centre, in Pondicherry, India in 2020 with multiple episodes of vomiting. Subsequent to a left-sided pneumonectomy due to tuberculosis, she was diagnosed with BEPS. Generally, patients with BEPS are clinically stable, afebrile with no fluid expectoration and have a normal white blood cell count. Bronchoscopy reveals an intact bronchial stump and pleural fluid cultures are often sterile. In terms of management, close monitoring and early detection of a bronchopleural fistula are the key points. BEPS should be a differential diagnosis in case of a drop in the air-fluid level of the post-pneumonectomy space. Awareness of this entity is crucial as it helps prevent unnecessary and morbid surgical interventions.

Abstract
PURPOSE/OBJECTIVE(S) To assess long-term differences in patient-reported outcomes in bowel and urinary domains between intensity-modulated radiotherapy (IMRT) and intensity-modulated proton therapy (IMPT) for prostate cancer. MATERIALS/METHODS Bowel function (BF), urinary irritative/obstructive symptoms (UO), and urinary incontinence (UI) domains of EPIC-26 were collected in patients with T1-T2 prostate cancer receiving IMRT or IMPT at a tertiary cancer center (2015-2018). Mean changes in domain scores were analyzed from pretreatment to 24 months post-radiotherapy for each modality. A clinically meaningful change was defined as a score change >50% of the standard deviation of a baseline score. RESULTS A total of 82 patients treated with IMRT (52.2%) and 56 patients treated with IMPT (53.3%) completed the questionnaire at baseline and 24 months post-RT. There were no baseline differences in domain scores between treatment modalities. At 24 months post-radiotherapy, there was significant and clinically meaningful decline of BF mean score in the IMRT cohort (-4.52 [range -50, 29.17], p = 0.003), whereas the decline in BF score did not reach statistical significance (-1.88 [range -37.5,50], p = 0.046) when accounting for the Bonferroni adjustment nor clinical relevance in the IMPT cohort. A higher proportion of patients treated with IMRT had a clinically relevant reduction in BF when compared with IMPT (47.37% vs 25.93%, p = 0.017). The mean changes in UI and UO scores of the IMRT and IMPT cohorts were neither statically significant nor clinically relevant. CONCLUSION IMPT has less decrement in BF than IMRT at 24 months post-RT, while there was no differential effect on UO and UI.

Abstract
Objective: To investigate the impact of combined use and timing of arterial-venous extracorporeal membrane oxygenation (VA-ECMO) with intra-aortic balloon pump (IABP) on the prognosis of patients with acute myocardial infarction complicated with cardiogenic shock (AMICS). Methods: This was a prospective cohort study, patients with acute myocardial infarction and cardiogenic shock who received VA-ECMO support from the Heart Center of Lanzhou University First Hospital from March 2019 to March 2022 in the registration database of the Chinese Society for Extracorporeal Life Support were enrolled. According to combination with IABP and time point, patients were divided into VA-ECMO alone group, VA-ECMO+IABP concurrent group and VA-ECMO+IABP non-concurrent group. Data from 3 groups of patients were collected, including the demographic characteristics, risk factors, ECG and echocardiographic examination results, critical illness characteristics, coronary intervention results, VA-ECMO related parameters and complications were compared among the three groups. The primary clinical endpoint was all-cause death, and the safety indicators of mechanical circulatory support included a decrease in hemoglobin greater than 50 g/L, gastrointestinal bleeding, bacteremia, lower extremity ischemia, lower extremity thrombosis, acute kidney injury, pulmonary edema and stroke. Kaplan-Meier survival curves were used to analyze the survival outcomes of patients within 30 days of follow-up. Using VA-ECMO+IABP concurrent group as reference, multivariate Cox regression model was used to evaluate the effect of the combination of VA-ECMO+IABP at different time points on the prognosis of AMICS patients within 30 days. Results: The study included 68 AMICS patients who were supported by VA-ECMO, average age was (59.8±10.8) years, there were 12 female patients (17.6%), 19 cases were in VA-ECMO alone group, 34 cases in VA-ECMO+IABP concurrent group and 15 cases in VA-ECMO+IABP non-concurrent group. The success rate of ECMO weaning in the VA-ECMO+IABP concurrent group was significantly higher than that in the VA-ECMO alone group and the VA-ECMO+IABP non-concurrent group (all P<0.05). Compared with the ECMO+IABP non-concurrent group, the other two groups had shorter ECMO support time, lower rates of acute kidney injury complications (all P<0.05), and lower rates of pulmonary edema complications in the ECMO alone group (P<0.05). In-hospital survival rate was significantly higher in the VA-ECMO+IABP concurrent group (28 patients (82.4%)) than in the VA-ECMO alone group (9 patients) and VA-ECMO+IABP non-concurrent group (7 patients) (all P<0.05). The survival rate up to 30 days of follow-up was also significantly higher surviving patients within were in the ECMO+IABP concurrent group (26 cases) than in VA-ECMO alone group (9 patients) and VA-ECMO+IABP non-concurrent group (4 patients) (all P<0.05). Multivariate Cox regression analysis showed that compared with the concurrent use of VA-ECMO+IABP, the use of VA-ECMO alone and non-concurrent use of VA-ECMO+IABP were associated with increased 30-day mortality in AMICS patients (HR=2.801, P=0.036; HR=2.985, P=0.033, respectively). Conclusions: When VA-ECMO is indicated for AMICS patients, combined use with IABP at the same time can improve the ECMO weaning rate, in-hospital survival and survival at 30 days post discharge, and which does not increase additional complications.

Guidelines for endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA): Joint Indian Chest Society (ICS)/Indian Association for Bronchology (IAB) recommendations. Lung India 2023; 40:368-400. [PMID: 37417095 PMCID: PMC10401980 DOI: 10.4103/lungindia.lungindia_510_22] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 12/30/2022] [Accepted: 01/31/2023] [Indexed: 07/08/2023] Open
Abstract
Over the past decade, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become an indispensable tool in the diagnostic armamentarium of the pulmonologist. As the expertise with EBUS-TBNA has evolved and several innovations have occurred, the indications for its use have expanded. However, several aspects of EBUS-TBNA are still not standardized. Hence, evidence-based guidelines are needed to optimize the diagnostic yield and safety of EBUS-TBNA. For this purpose, a working group of experts from India was constituted. A detailed and systematic search was performed to extract relevant literature pertaining to various aspects of EBUS-TBNA. The modified GRADE system was used for evaluating the level of evidence and assigning the strength of recommendations. The final recommendations were framed with the consensus of the working group after several rounds of online discussions and a two-day in-person meeting. These guidelines provide evidence-based recommendations encompassing indications of EBUS-TBNA, pre-procedure evaluation, sedation and anesthesia, technical and procedural aspects, sample processing, EBUS-TBNA in special situations, and training for EBUS-TBNA.

Measurement of Direct-Photon Cross Section and Double-Helicity Asymmetry at sqrt[s]=510 GeV in p[over →]+p[over →] Collisions. PHYSICAL REVIEW LETTERS 2023; 130:251901. [PMID: 37418716 DOI: 10.1103/physrevlett.130.251901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 11/04/2022] [Accepted: 04/28/2023] [Indexed: 07/09/2023]
Abstract
We present measurements of the cross section and double-helicity asymmetry A_{LL} of direct-photon production in p[over →]+p[over →] collisions at sqrt[s]=510 GeV. The measurements have been performed at midrapidity (|η|<0.25) with the PHENIX detector at the Relativistic Heavy Ion Collider. At relativistic energies, direct photons are dominantly produced from the initial quark-gluon hard scattering and do not interact via the strong force at leading order. Therefore, at sqrt[s]=510 GeV, where leading-order-effects dominate, these measurements provide clean and direct access to the gluon helicity in the polarized proton in the gluon-momentum-fraction range 0.02<x<0.08, with direct sensitivity to the sign of the gluon contribution.

Abstract
Objective: To analyze whole brain structural volume asymmetry in temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) using automated brain segmentation technology, and to investigate the application value of this technology in the diagnosis of TLE-HS and the performance in determining the location the lateralization of epileptogenic focus. Methods: Twenty-eight patients with TLE-HS were enrolled in the First Affiliated Hospital of Zhengzhou University from April 2019 to October 2020, including 13 females and 15 males, aged ranged from 18 to 63 (30±12) years, and these patients were divided two group according to the epilepsy lateralization, left TLE-HS(LTLE-HS) group (n=11), right TLE-HS(RTLE-HS) group (n=17) and 28 normal controls [aged ranged from 18 to 49 (29±10) years]. All of these subjects underwent three-dimensional T1 weighted image (3D T1WI). The differences of brain structure and volumes in LTLE-HS, RTLE-HS and normal controls group were retrospectively analyzed, and Pearson's correlation coefficient was used to evaluate the left and right volume correlations, and effect size was used for evaluating the differences in left and right volume averages. The asymmetry index (AI) of the left and right lateral volumes in each group was also calculated and compared among the three groups. Results: Standard volumes of all structures within the brain were asymmetric in the normal controls, LTLE-HS, and RTLE-HS groups, with smaller volumes of ipsilateral hippocampus than contralateral hippocampus in both the LTLE-HS and RTLE-HS groups(0.20%±0.03% vs 0.24%±0.02%,0.21%±0.03% vs 0.25%±0.02% respectively;both P<0.001), and smaller volumes of gray and white matter of the ipsilateral temporal lobe than contralateral in the LTLE-HS group(4.41%±0.38% vs 5.01%±0.43%,1.83%±0.22 % vs 2.22%±0.14%;both P<0.001). There was a moderate to strong linear correlation (0.553<r<0. 964,all P<0.05) between left and right lateral volumes in the normal controls, LTLE-HS, and RTLE-HS groups. All three groups showed the largest effect sizes in the cingulate gyrus (The effect sizes were 3.07, 4.85 and 4.22 in control, LTLE-HS and RTLE-HS, respectively.). The AI values of the hippocampus, temporal lobe gray matter, and temporal lobe white matter were statistically different among the three groups (-1.48±8.64 vs 15.91±10.15 vs -17.59±10.00, 7.46±2.67 vs 12.67±6.67 vs 3.67±6.15, 6.53±3.71 vs 19.91±9.85 vs 1.57±8.38;all P<0.001). Conclusion: Volumetric measurements by automated brain segmentation techniques can play an important role in preoperative assessment of TLE, and the asymmetry of brain volume may be of value in determining the localization and extent of the epileptogenic focus.

Abstract
A sudden drop of air-fluid level in the pneumonectomy space in the absence of a bronchopleural fistula and pleural infection is termed benign emptying of the post pneumonectomy space (BEPS). We herein report a case of benign emptying of pneumonectomy space, briefly review the literature and enumerate possible mechanisms for the same. It is an extremely rare entity and follows a benign course. Patients with BEPS are clinically stable, afebrile with no fluid expectoration, and have a normal white blood cell count. Bronchoscopy reveals an intact bronchial stump and pleural fluid cultures are often sterile. Close monitoring and early detection of a bronchopleural fistula is the management. Clinicians should keep BEPS among the differential diagnosis in case of a drop in the air-fluid level of the post pneumonectomy space. Awareness of this entity is crucial as it helps prevent unnecessary and morbid surgical interventions.

Abstract
Abstract
Background
In an effort to improve outcomes of STEMI patients, we developed a secure mobile application (app) to streamline real-time communication and coordination between multiple teams taking care of STEMI patients in a large health care system. The app includes multi-level alarm and notification systems, instant EKG transmission for quick interpretation, activation of the cardiac catheterization laboratory (CCL) after expert case review, secure video chat among team members facilitating clinical discussion, continuous updates on patients' clinical status and ambulance location tracking.
Purpose
One of the major shortcomings in STEMI system of care has been long delays in transfer of patients from non-PCI capable hospitals to a receiving center for primary PCI. To address the challenges of interhospital transfer, we designed a pilot project employing the app for STEMI transfer from a first contact hospital to our CCL. This report assesses the effect of the app on door-to-device time by comparing the key metric for STEMI transfer before (historic) and after app launch.
Methods
The pilot project involved key leadership stakeholders from Emergency Medicine and Nursing Departments at the referring hospital, CCL and our transfer center. During pilot period (July 2021 to January 2022) the referring center activated STEMI alarms using app activation in parallel with the previously established STEMI activation process via traditional phone calls to the transfer center. The built-in workflow redundancy was introduced to ensure the rapid and efficient, and at the same time, safe and reliable response to STEMI alert. In preparation for the pilot, more than 250 people were provisioned accounts, trained on their user-specific roles and scheduled in the app according to their schedules.
Results
A total of 40 suspected STEMIs were activated through the app during the pilot study; among them 30 cases were accepted for transfer and 10 rejected. After excluding patients who expired during transfer, were intubated, or had normal coronaries, final study population included 13 STEMI cases activated through the app. These cases were compared with 43 STEMIs activated through the traditional pathway from January 2019 to July 2021 before app launch. After implementing the app, the mean door-to-device time for STEMI transfer decreased from 120.3±48.3 to 91.8±15.4 min (P=0.002) (Figure 1). The significant improvement, 29 min (24%), of the key metric for interhospital transfer resulted in all STEMI cases meeting AHA goal of door-to-device time ≤120 minutes after the app launch. The respective percent of STEMI cases meeting the goal before app was 71% (Figure 2).
Conclusions
Implementation of a mobile app into STEMI workflow of a large urban healthcare system had a significant impact on the quality of care for transfer of STEMI patients, which has also helped bring our clinical practice closer to the AHA guidelines pertaining to the first door-to-device time.

Localization of CgVPE1 in secondary cell wall formation during tracheary element differentiation in the pericarp of Citrus grandis 'Tomentosa' fruits. PLANTA 2022; 256:89.

Abstract
CgVPE1 is important in the differentiation of TE cells in C. grandis 'Tomentosa' fruits as it may directly affects secondary cell wall construction while participating in PCD. The vacuolar processing enzyme (VPE) plays an important role in both developmental and environmentally inducible programmed cell death (PCD); it was originally identified as a cysteine protease localized in the vacuole to activate and mature vacuolar proteins in plants. Interestingly, we found a VPE called CgVPE1 to be associated with deposition of the secondary cell wall in tracheary element (TE) cells in the pericarp of Citrus grandis 'Tomentosa' fruits. We then used ultrathin sections and the TUNEL assay to verify that PCD is involved in TE development. Furthermore, CgVPE1 was found to be mainly expressed in secretory cavities and TEs in the pericarp of Citrus grandis 'Tomentosa' fruits. Immunolocalization of CgVPE1 in the pericarp indicated that CgVPE1 is mainly distributed in the central large vacuole, endoplasmic reticulum, Golgi vesicles, cytosol, and secondary wall before TE maturation. CgVPE1 appeared earlier in the endoplasmic reticulum and Golgi vesicles of TEs cells. The vesicles containing CgVPE1 near the large central vacuole and secondary wall were observed, respectively. CgVPE1 proteins content in the cytoplasm decreased sharply, while the CgVPE1 content in the secondary cell wall did not change significantly after vacuole rupture. CgVPE1 protein contents in the secondary cell wall were significantly reduced until the TE cells developed into hollow thick-walled cells. Furthermore, labeling of VPE homologues in Arabidopsis thaliana using immunoelectron microscopy with anti-CgVPE1 antibody revealed that VPE homologues were specifically distributed in the secondary cell wall of stem TEs. Overall, these results suggested that CgVPE1 is not only involved PCD during TE cell development; furthermore, it may directly participate in the construction of plant secondary cell walls.

Abstract
OBJECTIVE Salmonella isolates have been discovered in many regions of the world. We investigated the prevalence and resistance of Salmonella isolates in raw milk of healthy dairy cows on farms in different regions of Henan Province, China. MATERIALS AND METHODS From July 2020 to November 2021, 422 raw milk samples were collected. The minimum inhibitory concentrations (MICs) of 16 antimicrobial agents against 89 Salmonella strains detected from the raw milk samples were determined using the broth microdilution method, and the resistance genes for fluoroquinolones were identified using polymerase chain reaction. RESULTS Eighty-nine (21.09%) Salmonella isolates were recovered from 422 raw milk samples. The Salmonella strains exhibited high resistance to amoxicillin (100.00%), tylosin (95.50%), and lincomycin (95.50%). Additionally, tigecycline showed good activity against Salmonella, with an MIC50 of 0.25 μg/mL. All Salmonella isolates showed multidrug resistance (MDR), and >50% of the strains showed resistance to more than six antimicrobials. The strains from Jiaozuo exhibited 100% resistance to amoxicillin, terramycin, tylosin, and lincomycin. Two efflux pump genes, oqxA and oqxB, had the highest carrying rates of 66.29% and 64.04%, respectively. Additionally, the carrying rates of oqxA and oqxB were high in Shangqiu, Zhengzhou, and Jiaozuo. The carrying rates of aac(6')-Ib-cr in Shangqiu and Zhengzhou were 33.33% and 38.46%, respectively. CONCLUSIONS This study revealed a high prevalence of Salmonella isolates obtained from raw milk of healthy dairy cows in different regions of Henan Province, China. The Salmonella strains exhibited various degrees of MDR. Salmonella can be transmitted to humans via consumption of contaminated raw milk; thus, the presence of resistance genes poses a potential threat to public health, highlighting the need for vigilant monitoring of Salmonella isolates.

Abstract
Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a severe, idiosyncratic reaction to a drug which presents after a prolonged latency period. Although it most commonly occurs with aromatic anticonvulsants, antibiotics are also occasionally implicated. A 50-year-old male was admitted for left pyopneumothorax. He was started on intravenous piperacillin-tazobactam (Pip/Taz) and clindamycin. After 10 days of treatment, he developed high grade fever with maculopapular rashes with areas of scaling. He had elevated WBC counts with eosinophils of 21% and raised serum transaminases. After excluding other possible etiologies for febrile illness, a possibility of DRESS was considered. Naranjo scale, used for causality assessment, yielded a total score of 6, pointing toward probable adverse drug reaction. Also, the patient had 6 out of the 7 inclusion criteria for DRESS as per European Registry of Severe Cutaneous Adverse Reaction (RegiScar) scoring. Pip/Taz was found to be causative drug and was discontinued. He was conservatively managed with antipyretics and topical steroids. Fever subsided the day after stopping Pip/Taz and his rashes resolved gradually. In conclusion the possibility of antibiotics-induced DRESS should be considered and high index of vigilance is advised.

Abstract
Silicosis, an occupational menace is an irreversible lung disease caused by inhalation of tiny particles of crystalline silica. It is an occupational hazard both in industrialized as well as developing nations. Thoracic involvement is commonly described following exposure to silica, but extrathoracic involvement is a rare occurrence and often an incidental finding. It can manifest as calcifications in the liver, spleen, abdominal, axillary and cervical lymph nodes in addition to intrathoracic involvement. Silicosis as a cause of splenic calcifications often gets buried under the common differentials like tuberculosis, acquired immunodeficiency syndromes, amyloidosis, and Gamna-Gandy bodies. We herein describe a case of chronic complicated silicosis with splenic calcifications which appear similar to intrathoracic calcifications.

Abstract
BACKGROUND Structural variations (SVs, defined as DNA variants ≥50 bp) have been associated with various complex human diseases. However, research to screen the whole genome for SVs predisposing to psoriasis is still lacking. OBJECTIVES This study aimed to investigate the association of SVs and psoriasis. METHODS We performed a genome-wide screen on SVs using an imputation method on 5 independent cohorts with 45,386 subjects from the Chinese Han population. Fine mapping analysis, genetic interaction analysis and RNA expression analysis were conducted to explore the mechanism of SVs. RESULTS We obtained 4,535 SVs in total and identified 2 novel deletions (esv3608550, OR=2.73, P<2.00×10-308 ; esv3608542, OR=0.47, P=7.40×10-28 ) at 6q21.33 (MHC), 1 novel Alu element insertion (esv3607339, OR=1.22, P=1.18×10-35 ) at 5q33.3 (IL12B), and confirmed 1 previously reported deletion (esv3587563, OR=1.30, P=9.52×10-60 ) at 1q21.2 (LCE) for psoriasis. Fine mapping analysis including SNPs and small Insertions/Deletions (InDels) revealed that esv3608550 and esv3608542 were independently associated with psoriasis, and a novel independent SNP (rs9378188, OR=1.65, P=3.46×10-38 ) was identified at 6q21.33. By genetic interaction analysis and RNA expression analysis, we speculate that the association of 2 deletions at 6q21.33 with psoriasis might relate to their influence on the expression of HLA-C. CONCLUSIONS Our study constructed the most comprehensive SV map for psoriasis thus far and enriched the genetic architecture and pathogenesis of psoriasis as well as highlighted the nonnegligible impact of SVs on complex diseases.

Abstract
Background:Psoriatic arthritis (PsA) is a chronic inflammatory arthritis with progressive, erosive destruction associated with functional impairment. Principles of treat-to-target (T2T) have been widely used in rheumatoid arthritis, which has powerfully improved patient outcomes. In 2017, the concept of T2T has proposed to apply in PsA patients. However, the awareness and implementation of evidence-based T2T treatment guidelines varies across different geographical regions of China, hospital grades, professional status and specialities.Objectives:The study aimed to investigate Rheumatologists’ views and experiences in managing PsA patients with T2T strategy in china.Methods:A cross-sectional questionnaire survey of Rheumatologists in China from 5 August to 15 August 2020 was conducted for this study. Rheumatologists were contacted by WeChat (a Chinese cell/web app) and asked to complete a web-based questionnaire anonymously. The electronic questionnaire was sent out by the internet platform of WenJuanXing via WeChat (https://www.wjx.cn/). The questionnaire was designed to collect: (a) demographic information; (b) patient management in clinical practice for Rheumatologists; (c) familiarity and application of T2T strategy in Rheumatologists. P values ≤0.05 were considered significant.Results:(1) A total of 823 rheumatologists (69.87% female, 30.13% male) provided valid answers to the questionnaire. 71.09% of the participants major in Modern Western Medicine, 28.91% major in traditional chinese medicine. A total of 75.94% worked in Grade-A Tertiary Hospital. A total of 52.73% had more than 10 years of work experience and 63.55% had High-level title. (2) More than half of the patients were followed up by 69% Rheumatologists in their daily practice. The proportion of follow-up patients increased powerfully in the group of Rheumatologists who major in Modern Western Medicine (P=0.014), work in Grade-A Tertiary Hospital (P<0.001), have more than 10 years of work experience (P<0.001) and High-level title (P<0.001). (3) 36.45% Rheumatologist thought the frequency for patient disease activity assessment was every 1 month and 53.1% was every 3 months. And 41.7% Rheumatologist prefer to use PASDAS for disease activity criteria, and only 3.6% choose MDA. (4) A total of 62.43% thought they were familiar with T2T strategy, and 83.6% Rheumatologists applied T2T strategy in clinical practice. Among 135 Rheumatologists who did not apply T2T strategy, 62.2% of Rheumatologists thought that the main barrier to T2T application was that they did not fully understand the strategy. The frequency of application of T2T strategy in clinical practice was significantly different between Rheumatologists who major in Modern Western Medicine (60.75%) and traditional chinese medicine (22.84%) (P=0.023).Conclusion:In china, the management of PsA patients need to be standardized to improve patient outcomes. And the promotion of T2T strategy in PsA need to be further strengthened.References:[1]Smolen JS, Schöls M, Braun J,et al.

Abstract
Malignant peripheral nerve sheath tumours (MPNSTs) are rare soft tissue tumors that arise from pre-existing plexiform neurofibromas or within a normal peripheral nerve. They are aggressive tumors with high rates of recurrence and distant metastases, the most common sites of metastasis being the lung followed by bone. A 46 year old gentleman presented with breathlessness and chest pain three years after post amputation of left thumb for an ulcerative growth. CECT thorax showed a left upper lobe mass with pleural and pericardial effusion. Within a month of presentation he worsened and succumbed to the disease. Antemortem biopsy of the left hand ulcerative growth showed features suggestive of malignant peripheral nerve sheath tumour- epithelioid variant and post mortem liver and lung biopsy showed metastasis of MPNST. The diagnosis was a malignant peripheral nerve sheath tumor with lung, liver and cardiac metastasis. This case report aims to highlight the importance of upfront aggressive multimodality local therapy for achieving local disease control in patients presenting with localised MPNST and regular follow up for early detection of relapse and metastasis.

CgPBA1 may be involved in nuclear degradation during secretory cavity formation by programmed cell death in Citrus grandis 'Tomentosa' fruits. PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2021; 160:306-314.

Abstract
Caspase-3 is the crucial executor caspase of apoptosis in mammalian cells, which is essential for chromatin condensation and DNA fragmentation. Although plants have no caspase-3 homologs, PBA1 acts as a plant caspase-3-like enzyme in plant programmed cell death (PCD). PCD occurs during the formation of secretory cavities in Citrus fruits; hence, secretory cavities could be utilized as a new cell biology model for investigating the regulatory mechanisms of plant PCD. To further study the association between PBA1 and PCD during secretory cavity development in Citrus fruits, CgPBA1 was identified in the fruit of Citrus grandis 'Tomentosa'. The temporal and spatial expression of CgPBA1 during secretory cavity development were analyzed using quantitative real-time PCR and in situ hybridization, and the morphological changes in the apoptotic cell nuclei were observed using TUNEL assay and ultra-thin section technology. The results revealed that the full-length cDNA of CgPBA1 contains a 711 bp ORF that encodes a putative protein containing 236 amino acid with a proteasome-β-6 functional domain that belongs to the Ntn hydrolase super family. CgPBA1 was predominantly expressed in the secretory cavities; its expression changes coincided with the morphological changes and DNA fragmentation in apoptotic cell nuclei. The green fluorescent fusion protein of CgPBA1 is also located in the nucleus of tobacco epidermal cells. Based on previous research and the findings of the present study, we speculate that CgPBA1 is a highly functional conserved protein in plants, and it might be involved in nuclear degradation during PCD for secretory cavity formation in C. grandis 'Tomentosa' fruits.

Abstract
Streptomyces belongs to the Actinomycetes group of bacteria which are gram-positive non acid-fast bacilli, widely recognised for their potential to produce antimicrobials active against bacterial, mycobacterial, parasitic and fungal infections. They commonly cause cutaneous infections following traumatic inoculation. Visceral infections are relatively rare and limited to immunocompro-mised hosts. We describe a case of Streptomyces pneumonia in a healthy immunocompetent female, who when investigated for voluntary kidney donation, resulted in the isolation of Streptomyces species from bronchial wash cultures. Streptomyces, a potential pathogen in immunocompetent hosts is frequently underdiagnosed. Once isolated, both physicians and microbiologists should pay attention to differentiate true infection from contamination.

Abstract
OBJECTIVE To observe the intervention effect of circular ribonucleic acid (circRNA) 010567 on myocardial infarction (MI)-induced myocardial fibrosis (MF) in rats, and to explore whether its mechanism of action is related to the regulation on the transforming growth factor-β1 (TGF-β1) signaling pathway. MATERIALS AND METHODS The rat model of acute MI was established using ligation of the left anterior descending coronary artery. Model rats were randomly divided into circRNA 010567 siRNA group and Model group, with sham operation group as Control group. The effects of circRNA 010567 on the cardiac function, MF, myocardial apoptosis, mRNA, and protein expression levels of TGF-β1 and Smad3 in heart tissues of MI rats were detected using the small animal ultrasound system, Masson staining, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining, reverse transcription-polymerase chain reaction (RT-PCR), and Western blotting, respectively. RESULTS Compared with Control group, Model group had significantly decreased cardiac function, significantly lower left ventricular ejection fraction (LVEF), and left ventricular fractional shortening (LVFS), markedly increased left ventricular end-diastolic diameter (LVDd), and left ventricular end-systolic diameter (LVDs), severe MF, as well as a significantly higher apoptosis rate of myocardial cells, and evidently increased mRNA and protein levels of TGF-β1 and Smad3 in heart tissues. Compared with Model group, circRNA 010567 siRNA group had evidently improved cardiac function, significantly higher LVEF and LVFS, markedly decreased LVDd and LVDs, alleviated MF, a significantly lower apoptosis rate of myocardial cells, and evidently decreased mRNA and protein levels of TGF-β1 and Smad3 in heart tissues. CONCLUSIONS CircRNA 010567 siRNA can improve the cardiac function, alleviate the MF, and inhibit the myocardial apoptosis, thereby further suppressing MI-induced MF, whose mechanism may be related to the inhibition on the TGF-β1 signaling pathway.

Abstract
OBJECTIVE The aim of this study was to investigate the effects of butylphthalide on oxidative stress and inflammatory response in rats with myocardial infarction through the protein kinase B/nuclear factor E2-related factor 2 (Akt/Nrf2) signaling pathway. MATERIALS AND METHODS A total of 36 Sprague-Dawley rats were randomly divided into three groups, including sham group (n=12), model group (n=12) and butylphthalide group (n=12). In the sham group, the heart was exposed, and normal saline was intraperitoneally injected after the operation. In the model group, acute myocardial infarction (AMI) model was established, and normal saline was intraperitoneally injected after the operation. In the butylphthalide group, AMI model was established, and butylphthalide was intraperitoneally injected after the operation. After intervention for 4 weeks, the rats were killed, and the samples were collected. The morphology of heart tissues was observed via hematoxylin-eosin (HE) staining. The expression of nicotinamide adenine dinucleotide phosphate oxidase-1 (NOX-1) was detected via immunohistochemistry. The protein expressions of phosphorylated Akt (p-Akt) and p-Nrf2 were detected via Western blotting. Moreover, the content of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) was detected via enzyme-linked immunosorbent assay (ELISA). The messenger ribonucleic acid (mRNA) expression levels of IL-1β, TNF-α and NOX-1 were detected via quantitative Polymerase Chain reaction (qPCR). Furthermore, the apoptosis rate of the cells was detected via terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay. RESULTS The morphology of heart tissues was significantly damaged in the model group and butylphthalide group compared with the sham group. However, it was significantly improved in the butylphthalide group when compared with the model group. The expression level of NOX-1 increased markedly in the model group and butylphthalide group compared with the sham group (p<0.05). However, it was remarkably reduced in the butylphthalide group compared with the model group (p<0.05). Meanwhile, the protein expression levels of p-Akt and p-Nrf2 were significantly higher in the model group and butylphthalide group than those of the sham group (p<0.05). However, the protein expression levels of p-Akt and p-Nrf2 in the butylphthalide group were remarkably lower than the model group (p<0.05). The mRNA expression levels of IL-1β, TNF-α and NOX-1 were markedly higher in the model group and butylphthalide group than those of the sham group (p<0.05). However, they remarkably declined in the butylphthalide group compared with the model group (p<0.05). In addition, the content of IL-1β and TNF-α increased in the model group and butylphthalide group when compared with the sham group (p<0.05). The content of IL-1β and TNF-α in the butylphthalide group was significantly lower than the model group (p<0.05). Furthermore, the apoptosis rate was significantly higher in the model group and butylphthalide group than the sham group (p<0.05), which was significantly lower in the butylphthalide group than the model group (p<0.05). CONCLUSIONS Butylphthalide inhibits inflammatory and oxidative stress responses after AMI by regulating the Akt/Nrf2 signaling pathway, thereby inhibiting myocardial apoptosis and benefiting the morphological repair of myocardial tissues.

Abstract
OBJECTIVE To elucidate whether circHIPK3 could inhibit proliferation and induce apoptosis of cardiomyocytes via binding to miRNA-124-3p, thus aggravating myocardial ischemia/reperfusion (IR) injury. MATERIALS AND METHODS CircHIPK3 expression in HCM cells simulated with myocardial I/R was determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Influences of circHIPK3 on myocardial injury marker levels of lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) in the in vitro model of myocardial I/R were evaluated using the relative commercial kits. The regulatory effects of circHIPK3 on proliferative ability and apoptosis of simulated HCM cells were examined by Cell Counting Kit-8 (CCK-8) assay and flow cytometry, respectively. Dual-Luciferase reporter gene assay was conducted to verify the binding of circHIPK3 to miRNA-124-3p. Finally, the roles of the circHIPK3/miRNA-124-3p axis in regulating apoptotic gene expressions and cardiomyocyte repair after myocardial I/R were explored. RESULTS CircHIPK3 was highly expressed in HCM cells with simulated myocardial I/R relative to those with normoxic treatment. The overexpression of circHIPK3 in simulated HCM cells decreased levels of LDH, SOD and GSH-PX, whereas increased the MDA level. Inhibited proliferation and accelerated apoptosis were observed in simulated HCM cells overexpressing circHIPK3. Western blot analyses illustrated that circHIPK3 overexpression upregulated pro-apoptotic Bax, and downregulated anti-apoptotic Bcl-2. Subsequently, we confirmed the binding between circHIPK3 and miRNA-124-3p. Rescue experiments demonstrated that circHIPK3 overexpression reversed the protective effects of miRNA-124-3p on myocardial I/R and cardiomyocyte apoptosis. CONCLUSIONS CircHIPK3 inhibits proliferative ability and induces apoptosis of cardiomyocytes after myocardial I/R injury by binding to miRNA-124-3p, which may serve as a potential therapeutic target for I/R.

Abstract
Spontaneous Pneumomediastinum (SPM) is a benign, self-limiting but potentially fatal condition specially in underlying pulmonary disease. Spontaneous pneumomediastinum is rarely associated with connective tissue related interstitial lung disease. We report a patient of interstitial pneumonia with autoimmune features who presented with acute onset breathlessness and was diagnosed to have spontaneous pneumomediastinum, pneumopericardium, and subcutaneous emphysema. This condition are easily diagnosed by clinical findings like Hamman's crunch and plain chest radiographs in cases with normal underlying lungs. In cases of extensive pulmonary fibrosis like Interstitial Lung Diseases both clinical findings and Plain chest radiographs can be inconclusive. CT of thorax is the gold standard diagnostic modality. Pneumopericardium rarely leads to cardiac tamponade, which requires immediate surgical intervention. We conclude that every case of acute onset breathlessness in a known case of interstitial lung disease may not necessarily be an exacerbation of the underlying lung condition. Physicians need to have a high index of suspicion while treating patients of interstitial lung disease. CT thorax is gold standard diagnostic modality especially in presence of fibrotic lung diseases.

Abstract
The PHENIX collaboration presents first measurements of low-momentum (0.4<p_{T}<3 GeV/c) direct-photon yields from Au+Au collisions at sqrt[s_{NN}]=39 and 62.4 GeV. For both beam energies the direct-photon yields are substantially enhanced with respect to expectations from prompt processes, similar to the yields observed in Au+Au collisions at sqrt[s_{NN}]=200. Analyzing the photon yield as a function of the experimental observable dN_{ch}/dη reveals that the low-momentum (>1 GeV/c) direct-photon yield dN_{γ}^{dir}/dη is a smooth function of dN_{ch}/dη and can be well described as proportional to (dN_{ch}/dη)^{α} with α≈1.25. This scaling behavior holds for a wide range of beam energies at the Relativistic Heavy Ion Collider and the Large Hadron Collider, for centrality selected samples, as well as for different A+A collision systems. At a given beam energy, the scaling also holds for high p_{T} (>5 GeV/c), but when results from different collision energies are compared, an additional sqrt[s_{NN}]-dependent multiplicative factor is needed to describe the integrated-direct-photon yield.

Abstract
Asymmetric nuclear collisions of p+Al, p+Au, d+Au, and ^{3}He+Au at sqrt[s_{NN}]=200 GeV provide an excellent laboratory for understanding particle production, as well as exploring interactions among these particles after their initial creation in the collision. We present measurements of charged hadron production dN_{ch}/dη in all such collision systems over a broad pseudorapidity range and as a function of collision multiplicity. A simple wounded quark model is remarkably successful at describing the full data set. We also measure the elliptic flow v_{2} over a similarly broad pseudorapidity range. These measurements provide key constraints on models of particle emission and their translation into flow.

[PMID: 30442264 DOI: 10.1016/j.bja.2018.08.005] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Revised: 07/19/2018] [Accepted: 08/06/2018] [Indexed: 10/28/2022] Open
Abstract
BACKGROUND The African Surgical Outcomes Study (ASOS) showed that surgical patients in Africa have a mortality twice the global average. Existing risk assessment tools are not valid for use in this population because the pattern of risk for poor outcomes differs from high-income countries. The objective of this study was to derive and validate a simple, preoperative risk stratification tool to identify African surgical patients at risk for in-hospital postoperative mortality and severe complications. METHODS ASOS was a 7-day prospective cohort study of adult patients undergoing surgery in Africa. The ASOS Surgical Risk Calculator was constructed with a multivariable logistic regression model for the outcome of in-hospital mortality and severe postoperative complications. The following preoperative risk factors were entered into the model; age, sex, smoking status, ASA physical status, preoperative chronic comorbid conditions, indication for surgery, urgency, severity, and type of surgery. RESULTS The model was derived from 8799 patients from 168 African hospitals. The composite outcome of severe postoperative complications and death occurred in 423/8799 (4.8%) patients. The ASOS Surgical Risk Calculator includes the following risk factors: age, ASA physical status, indication for surgery, urgency, severity, and type of surgery. The model showed good discrimination with an area under the receiver operating characteristic curve of 0.805 and good calibration with c-statistic corrected for optimism of 0.784. CONCLUSIONS This simple preoperative risk calculator could be used to identify high-risk surgical patients in African hospitals and facilitate increased postoperative surveillance. CLINICAL TRIAL REGISTRATION NCT03044899.

Robust Hydrophobic Surfaces from Suspension HVOF Thermal Sprayed Rare-Earth Oxide Ceramics Coatings. Sci Rep 2018; 8:6973.

Abstract
This study has presented an efficient coating method, namely suspension high velocity oxy-fuel (SHVOF) thermal spraying, to produce large super-hydrophobic ceramic surfaces with a unique micro- and nano-scale hierarchical structures to mimic natural super-hydrophobic surfaces. CeO2 was selected as coatings material, one of a group of rare-earth oxide (REO) ceramics that have recently been found to exhibit intrinsic hydrophobicity, even after exposure to high temperatures and abrasive wear. Robust hydrophobic REO ceramic surfaces were obtained from the deposition of thin CeO2 coatings (3–5 μm) using an aqueous suspension with a solid concentration of 30 wt.% sub-micron CeO2 particles (50–200 nm) on a selection of metallic substrates. It was found that the coatings’ hydrophobicity, microstructure, surface morphology, and deposition efficiency were all determined by the metallic substrates underneath. More importantly, it was demonstrated that the near super-hydrophobicity of SHVOF sprayed CeO2 coatings was achieved not only by the intrinsic hydrophobicity of REO but also their unique hierarchically structure. In addition, the coatings’ surface hydrophobicity was sensitive to the O/Ce ratio, which could explain the ‘delayed’ hydrophobicity of REO coatings.

Abstract
This Letter reports the successful use of feedback from a spin polarization measurement to the revolution frequency of a 0.97 GeV/c bunched and polarized deuteron beam in the Cooler Synchrotron (COSY) storage ring in order to control both the precession rate (≈121 kHz) and the phase of the horizontal polarization component. Real time synchronization with a radio frequency (rf) solenoid made possible the rotation of the polarization out of the horizontal plane, yielding a demonstration of the feedback method to manipulate the polarization. In particular, the rotation rate shows a sinusoidal function of the horizontal polarization phase (relative to the rf solenoid), which was controlled to within a 1 standard deviation range of σ=0.21 rad. The minimum possible adjustment was 3.7 mHz out of a revolution frequency of 753 kHz, which changes the precession rate by 26 mrad/s. Such a capability meets a requirement for the use of storage rings to look for an intrinsic electric dipole moment of charged particles.

Abstract
The invasion of the muscularis propria is defined as T2 stage in esophageal squamous cell carcinoma. Evidence is lacking regarding whether the T2 substage based on anatomy may serve as a prognostic indicator. This study aims to confirm the prognostic value of the T2 substage. The clinicopathological characteristics of 120 patients who had pathologically verified T2 tumors between 2006 and 2011 at the Tianjin Medical University Cancer Institute and Hospital were retrospectively studied. Based on the invasion depth, tumors that had penetrated the circular muscle layer were defined as T2a, while T2b disease referred to those that had invaded the longitudinal muscle layer. Factors potentially related to survival were analyzed with univariate and multivariate analyses. The logistic regression model was used to examine the factors associated with lymph node metastasis. To verify the prognostic value of the T2 substage further, patients with T1b and T3 stage disease during the same period were selected for comparisons. The univariate and multivariate analyses demonstrated that the T2 substage and N stage were independent prognostic factors. The T2 substage was highly relevant to lymph node metastasis in the logistic regression model (P = 0.044). When T1b and T3 was considered, the survival of T2a patients was closer to that of T1b patients, while the survival of T2b patients was closer to that of T3 disease (P = 0.000). The T2 substage was an independent prognostic factor. Patients with T2a tumors displayed a favorable survival, while the prognosis of T2b patients was closer to that of T3 patients.

Abstract
A new experiment is described to detect a permanent electric dipole moment of the proton with a sensitivity of 10-29 e ⋅ cm by using polarized "magic" momentum 0.7 GeV/c protons in an all-electric storage ring. Systematic errors relevant to the experiment are discussed and techniques to address them are presented. The measurement is sensitive to new physics beyond the standard model at the scale of 3000 TeV.

Abstract
Haploid cells contain one set of chromosomes and are amenable for genetic analyses. In mammals, haploidy exists only in gametes. An intriguing question is whether haploid cells can be derived from gametes. Recently, by application of haploid cell enrichment using fluorescence-activated cell sorting, stable haploid embryonic stem cells (haESCs) have been successfully derived from oocyte-derived parthenogenetic and sperm-derived androgenetic embryos from several species. Whilst both parthenogenetic and androgenetic (AG)-haESCs enable whole-genome genetic screening at the cellular level, such as screening of drug resistance or disease-related genes, AG-haESCs, after intracytoplasmic injection into oocytes, can also be used to produce alive semi-cloned mice. Nevertheless, one major drawback associated with wild-type AG-haESCs is the very low birth rate of healthy semi-cloned mice. Of interest, after inhibiting the expression of two paternally imprinted genes (H19 and Gtl2) in AG-haESCs by removal of their differentially DNA methylated regions, double-knockout AG-haESCs can efficiently and stably support the generation of healthy semi-cloned pups. Importantly, double-knockout AG-haESCs are feasible for multiple genetic manipulations, followed by efficient generation of semi-cloned mice carrying multiple genetic traits; thus they could be used to validate candidate loci that have been identified in genome-wide association studies of multigenic diseases by generation of mouse models carrying multiple alterations. Of note, by combining a CRISPR-Cas9 library and double-knockout AG-haESCs, semi-cloned mice carrying different mutant genes can be efficiently generated in one step, enabling functional mutagenic screening in mice. HaESCs, therefore, provide a powerful tool for genetic analyses in mammals at both the cellular and organismal levels.

How to Reach a Thousand-Second in-Plane Polarization Lifetime with 0.97-GeV/c Deuterons in a Storage Ring. PHYSICAL REVIEW LETTERS 2016; 117:054801.

Abstract
We observe a deuteron beam polarization lifetime near 1000 s in the horizontal plane of a magnetic storage ring (COSY). This long spin coherence time is maintained through a combination of beam bunching, electron cooling, sextupole field corrections, and the suppression of collective effects through beam current limits. This record lifetime is required for a storage ring search for an intrinsic electric dipole moment on the deuteron at a statistical sensitivity level approaching 10^{-29} e cm.

Centrality-Dependent Modification of Jet-Production Rates in Deuteron-Gold Collisions at √[s(NN)]=200 GeV. PHYSICAL REVIEW LETTERS 2016; 116:122301.

Abstract
Jet production rates are measured in p+p and d+Au collisions at sqrt[s_{NN}]=200 GeV recorded in 2008 with the PHENIX detector at the Relativistic Heavy Ion Collider. Jets are reconstructed using the R=0.3 anti-k_{t} algorithm from energy deposits in the electromagnetic calorimeter and charged tracks in multiwire proportional chambers, and the jet transverse momentum (p_{T}) spectra are corrected for the detector response. Spectra are reported for jets with 12<p_{T}<50 GeV/c, within a pseudorapidity acceptance of |η|<0.3. The nuclear-modification factor (R_{dAu}) values for 0%-100% d+Au events are found to be consistent with unity, constraining the role of initial state effects on jet production. However, the centrality-selected R_{dAu} values and central-to-peripheral ratios (R_{CP}) show large, p_{T}-dependent deviations from unity, challenging the conventional models that relate hard-process rates and soft-particle production in collisions involving nuclei.

Abstract
OBJECTIVE To study the incidence of positive t(14; 18) and myc gene rearrangement, and the clinical features and prognosis of concurrent positive t(14; 18) and myc gene rearrangement "double-hit lymphoma" (DHL) in diffuse large B cell lymphoma. METHODS The positive t(14; 18) and myc gene rearrangement in 106 cases of DLBCL were analyzed using interphase fluorescent in situ hybridization (FISH) technique. The expression of myc and bcl-2 proteins was determined by immunohistochemistry. The relationship of positive t(14; 18) and myc gene rearrangement with clinical features, pathogenesis and prognosis for the patients was analyzed. SPSS 16.0 software was used for statistical analysis. RESULTS Among the 106 cases, there were 27 (25.5%) cases with positive t(14; 18) and 13 (12.3%) cases with myc gene rearrangement, and 7 cases (6.6%) of DLBCL with concurrent t(14; 18)-positive and myc gene rearrangement. A relationship was observed between positive t(14; 18) and myc gene rearrangement (P=0.019). The follow-up data showed that the 7 DHL patients were in age of 52-84 years, the International Prognostic Index (IPI) scores were 3 in two cases, 4 in four cases and 5 in one case, and the ECOG scores were 3 in all the 7 cases. Four patients had bone marrow involvement and were combined with leukemia. The survival time ranged from 0.5 to 6 months, with a median survival of 4 months. The univariate analysis showed that B symptom, Ann Arbor stage, ECOG score, LDH level, IPI score, immunophenotype, bcl-2 protein expression, myc protein expression, and myc gene rearrangement were all associated with poor prognosis (P<0.05 for all). The multivariate analysis using a COX proportional hazard model confirmed that ECOG score, bcl-2 protein expression, myc protein expression, myc gene rearrangement, and immunophenotype were independent prognostic factors affecting survival (P<0.05 for all), among them, the myc gene rearrangement was the strongest prognostic factor (OR=4.337, P<0.001). CONCLUSIONS "Double-hit" DLBCL is rare and can be mainly identified only by molecular detection. Perhaps positive t(14; 18) and myc gene rearrangement play concurrent role in its "double-hit" pathogenesis. DHL are highly invasive, and most of DHL patients have poor prognosis. Further studies of larger case number are required to determine the pathologic features and the therapeutic strategy of this subgroup.
