Can thoraco-abdominal organ boundaries be accurately determined from X-ray and anthropometric surface scans? Implications for body armour system coverage and design. APPLIED ERGONOMICS 2024; 119:104311. [PMID: 38763088 DOI: 10.1016/j.apergo.2024.104311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Revised: 04/29/2024] [Accepted: 05/07/2024] [Indexed: 05/21/2024]
Abstract
To optimise soldier protection within body armour systems, knowledge of the boundaries of essential thoraco-abdominal organs is necessary to inform coverage requirements. However, existing methods of organ boundary identification are costly and time consuming, limiting widespread adoption for use on soldier populations. The aim of this study was to evaluate a novel method of using 3D organ models to identify essential organ boundaries from low dose planar X-rays and 3D external surface scans of the human torso. The results revealed that, while possible to reconstruct 3D organs using template 3D organ models placed over X-ray images, the boundary data (relating to the size and position of each organ) obtained from the reconstructed organs differed significantly from MRI organ data. The magnitude of difference varied between organs. The most accurate anatomical boundaries were the left, right, and inferior boundaries of the heart, and lateral boundaries for the liver and spleen. Visual inspection of the data demonstrated that 11 of 18 organ models were successfully integrated within the 3D space of the participant's surface scan. These results suggest that, if this method is further refined and evaluated, it has potential to be used as a tool for estimating body armour coverage requirements.

Abstract
OBJECTIVE To evaluate the feasibility and safety of one- stage bilateral video-assisted thoracic surgery (VATS) for resection of bilateral multiple pulmonary nodules (BMPNs). METHODS We analyzed the clinical characteristics, pathological features, perioperative outcomes and follow-up data of 41 patients with BMPNs undergoing one-stage bilateral VATS from July, 2011 to August, 2021. RESULTS One-stage bilateral VATS was performed uneventfully in 40 of the patients, and conversion to open surgery occurred in 1 case. The surgical approaches included bilateral lobectomy (4.9%), lobar-sublobar resection (36.6%) and sublobar-sublobar resection (58.5%) with a mean operative time of 196.3±54.5 min, a mean blood loss of 224.6±139.5 mL, a mean thoracic drainage duration of 4.7±1.1 days and a mean hospital stay of 14±3.8 days. Pathological examination revealed bilateral primary lung cancer in 15 cases, unilateral primary lung cancer in 21 cases and bilateral benign lesions in 5 cases. A total of 112 pulmonary nodules were resected, including 67 malignant and 45 benign lesions. Postoperative complications included pulmonary infection (5 cases), respiratory failure (2 cases), asthma attack (2 cases), atrial fibrillation (2 cases), and drug-induced liver injury (1 case). No perioperative death occurred in these patients, who had a 1-year survival rate of 97.6%. CONCLUSION With appropriate preoperative screening and perioperative management, one-stage bilateral VATS is feasible and safe for resection of BMPNs.

Abstract
BACKGROUND Thyroid cancer is one of the malignancy cancers. CircRNA, a non-coding RNA, plays an important role in the development of cancer. The relationship and roles of circ_0124055, miR-486-3p and MTA1 in thyroid cancer have not been reported. METHODS Real-time quantitative polymerase chain reaction (RT-qPCR) was performed to analyze the RNA levels of circ_0124055, miR-486-3p and MTA1. Western blot was conducted to analyze the protein levels of MTA1, Epithelial cadherin (E-cadherin) and Neuro cadherin (N-cadherin). Subcellular localization assay was used to analyze circ_0124055 location in thyroid cancer cells. Colony formation assay and 5-Ethynyl-2'-deoxyuridine (EdU) assay were carried out to analyze cell proliferation. Cell migration and invasion were analyzed by wound-healing assay and transwell assay. Flow cytometry assay was performed to investigate cell apoptosis. Dual-luciferase reporter assay and RIP assay were employed to analyze the interactions among circ_0124055, miR-486-3p and MTA1. Immunohistochemical (IHC) assay was performed to assess the expression of Ki67, MTA1 and E-cadherin in tumor tissues. Thyroid cancer tumor growth in vivo was evaluated by tumor xenograft mouse model assay. RESULTS The expression of circ_0124055 was up-regulated in tumor tissues and cells. Knockdown of circ_0124055 could inhibit thyroid cancer cell proliferation, migration and invasion and promote cell apoptosis, accompanied by the dysregulation of E-cadherin and N-cadherin expression. Circ_0124055 could target miR-486-3p, and miR-486-3p could target MTA1. MiR-486-3p inhibitor could restore the effect of circ_0124055 knockdown in the progression of thyroid cancer. Moreover, MTA1 overexpression weakened the inhibitory effects of miR-486-3p mimics on the progression of thyroid cancer. Further, circ_0124055 could influence tumor growth in vivo. CONCLUSION Circ_0124055 promoted the progression of thyroid cancer cells through the miR-486-3p /MTA1 axis.

Do thoracoabdominal organ boundaries differ between males and females? Implications for body armour coverage and design. APPLIED ERGONOMICS 2023; 106:103891. [PMID: 36113184 DOI: 10.1016/j.apergo.2022.103891] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 08/21/2022] [Accepted: 08/25/2022] [Indexed: 06/15/2023]
Abstract
To optimise fit and protection of body armour systems, knowledge of the location of thoracoabdominal organ boundaries is required. The aims of this study were (i) determine the effect of sex on essential and desirable thoracoabdominal organ boundaries, and (ii) compare essential thoracoabdominal organ boundaries with small and large hard ballistic plate sizes from the National Institute of Justice (NIJ) and determine if coverage requirements differ between sexes. 33 males and 33 females underwent supine magnetic resonance imaging of their thoracoabdominal organs. Male participants on average displayed more laterally and inferiorly positioned essential and desirable organ boundaries than females. Based on NIJ plate sizes, insufficient coverage of essential organs was identified for male and female participants. A greater range of body armour sizes and designs that better cater to the diverse anatomy of soldier populations is warranted, but must be considered in the context of ergonomic and performance implications.

Abstract
Abstract
Background
Cardiac graft failure may require repeat heart transplantation (HTx). Outcomes of patients that undergo repeat HTx have not been well described.
Methods
We compared patients that received repeat HTx with patients that received initial HTx by inquiring the United Network for Organ Sharing database between 2015–2021. The primary endpoint was all-cause mortality.
Results
A total of 19,805 HTx patients were included in the study. Patients that underwent repeat HTx (n=578, 3%) were younger (43.8±15.3 vs. 53.7±12.7 years, p<0.001) with lower body mass index (26.8±5.3 vs. 27.6±4.9 kg/m2, p<0.001) and worse renal function (Cr 1.8±1.4 vs. 1.4±0.9 mg/dl). Patients with repeat HTx had increased risk for 1-year mortality (hazard ratio 1.49 [1.16–1.90], p=0.002) compared to patients with initial HTx after adjusting for age, ethnicity, use of left ventricular assist device, UNOS recipient status, diabetes, ischemic time, donor age and predicted heart mass mismatch (Figure 1). Results did not change with the new allocation system (10/2018).
Conclusion
Repeat HTx occurred in 3% of a contemporary UNOS cohort and carried an increased and independent risk for mortality.

Abstract
Abstract
Aim
Achieving haemostasis intraoperatively is important for minimising blood loss, complications, and operation time. Suturing, cauterisation, fibrin glues and patches are used for this purpose. We explore Veriset, a patch consisting of polyethylene glycol and oxidised cellulose, to determine and compare its safety and effectiveness.
Method
Medline, Embase, Web of Science, Scopus, Cinahl and Cochrane databases were searched. Data points collected were Study/subject characteristics/demographics, surgery/specialty, time to haemostasis, proportion of haemostasis achieved, intraoperative adverse events, post operative complications, follow up time, and biochemical/histological analysis. Risk of Bias was assessed by Newcastle-Ottawa Scale
Results
Six studies were included; four human trials (3 RCTs, 1 case series) and two animal trials.
The human trials combined had 250 patients, with 147 using Veriset. In two RCTs, Veriset showed faster time to haemostasis and higher proportion of haemostasis achieved vs suturing and Tachosil haemostatic patch. In all three RCTs, no significant differences in adverse events and complications were seen between Veriset and suturing/Tachosil. Vascular, nephrectomy and hepatic surgery were investigated.
In the animal studies, the pig trial showed similar effectiveness and safety as the human trials. The rat study compared novel experimental patches to Veriset, and showed similar effectiveness to Veriset, at reduced costs.
Conclusions
Although current literature is scarce, Veriset is more effective than alternatives for haemostasis, with similar safety, although there are now other experimental patches that could have better health economic implications. Further clinical trials would be necessary to determine the breadth of applicable surgical fields for Veriset.

Abstract
Abstract
Aim
Fragility ankle fractures are traditionally managed conservatively or with open reduction internal fixation (ORIF). Tibiotalocalcaneal (TTC) nailing is an alternative option for the geriatric patient. This meta-analysis provides the most detailed analysis of hindfoot nailing for fragility ankle fractures.
Method
A systematic search was performed on MEDLINE, EMBASE, Cochrane Library, Scopus, Web of Science, identifying fourteen studies for inclusion. Studies including patients over 60 with a fragility ankle fracture, treated with TTC nail were included. Patients with a previous fracture of the ipsilateral limb, fibular nails, and pathological fractures were excluded.
Meta-regression analyses were performed to explore sources of heterogeneity, and publication bias was assessed using Egger's test.
Results
312 ankle fractures were included. The mean age was 77.3 (32–101) years. 26.9% were male, and 41.9% were diabetics. The pooled proportion of superficial infection, deep infection, implant failure, malunion, and all-cause mortality was 0.10 (95%CI:0.06–0.16; I2=44%), 0.08 (95%CI:0.06–0.11, I2=0%), 0.11 (95%CI:0.07–0.15,I2=0%), 0.11 (95%CI:0.06–0.18; I2=51%), and 0.27 (95%CI:0.20–0.34; I2=11%), respectively. The pooled mean post-operative OMAS score was 54.07 (95%CI:48.98–59.16; I2=85%). The best-fitting meta-regression model included age and percentage of male patients as covariates (p=0.0263), and were inversely correlated with higher OMAS scores. Egger's test (p=0.56) showed no significant publication bias.
Conclusions
TTC nailing is an adequate alternative option for fragility ankle fracture management. However, current evidence includes mainly case series with inconsistent outcome measures reported and post-operative rehabilitation protocols. Prospective RCTs with long follow-up times and large cohort sizes are needed to clearly guide the use of TTC nailing for ankle fractures.

Abstract
Abstract
Aim
Open tibial fractures can be difficult to manage - many factors could affect treatment and outcome, including being complicated by infection. We present a cohort of 244 patients and analyse which factors are significantly associated with infection outcome.
Method
Open tibia fractures treated at a major trauma centre between 2015–2021 were included.
Infection status was categorized into no infection, superficial infection, osteomyelitis. Data collected were Age, mode of injury, polytrauma, fibula status, Gustilo-Anderson (GA) classification, wound contamination, time to first procedure. time to definitive plastics procedure, time to definitive fixation, type of definitive fixation, smoking/diabetic status, and BMI.
Multicollinearity was calculated, with highly correlated factors removed. Multinomial logistic regression was performed. Chi-Squared test, with Post-Hoc Bonferroni correction was performed for complex categorical factors.
Results
244 patients were included. Polytrauma and fibula status, and type of definitive fixation were excluded from the multivariate model due to strong multicollinearity. Compared to non-infected outcome, patients with superficial infection had higher BMI (p<0.01), higher GA grade (p<0.01), and osteomyelitis patients had longer time to definitive fixation (p=0.049) and longer time to definitive plastics procedure (p=0.013), higher GA grade, and wound contamination.
Post-hoc analysis showed “no infection” was positively associated with GA-I (p=0.029) and GA-II (p<0.01), and negatively associated with GA-IIIC (p<0.01). Osteomyelitis was positively associated with GA-IIIc (p<0.01)
Conclusions
This study investigated associations between injury and presentation factors that may have been associated with infection. We suggest clinicians should give extra consideration to the factors highlighted during management and take preventative measures to mitigate the infection risk.

Abstract
Abstract
Aim
Fragility ankles fractures in the geriatric population are challenging to manage, due to fracture instability, soft tissue compromise, and patient co-morbidities. Traditional management options include open reduction internal fixation, or conservative treatment, both of which are fraught with high complication rates. We aimed to present functional outcomes of elderly patients with fragility ankle fractures treated with retrograde ankle fusion nails.
Method
171 patients received a tibiotalocalcaneal nail over a six-year period, but only twenty met the inclusion criteria of being over sixty and having poor bone stock. Primary outcome was mortality risk from co-morbidities according to Charlson co-morbidity index (CCI), and patients’ post-operative mobility status compared to pre-operative mobility. Secondary outcomes include intra-operative and post-operative complications, six-month mortality rate, time to mobilisation and union.
Results
Mean age was 77.82 years old. The average CCI was 5.05. Thirteen patients returned to their pre-operative mobility state. Patients with low CCI are more likely to return to pre-operative mobility status (p=0.16;OR=4.00).
Average time to bone union and mobilisation were 92.5 days and 7.63 days, respectively. Mean post-operative AOFAS ankle-hindfoot and Olerud-Molander scores were 53.0 and 50.9, respectively. There were four cases of superficial infection. Patients with high CCI were more likely to acquire superficial infections (p=0.264,OR=3.857). There were no deep infections, periprosthetic fractures, nail breakages, non-unions. Average follow-up time was 499.3 days.
Conclusions
Tibiotalocalcaneal nailing is an effective and safe option for managing fragility ankle fractures in the elderly. This technique leads to lower complication rates and earlier mobilisation than traditional fixation methods.

Application of coal fly ash in pavement subgrade stabilisation: A review. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2022; 312:114926.

Abstract
Expansive clays are found in many countries worldwide, and they exhibit inherent volume change during the seasonal moisture variation causing cracks, heaves, and damages to the overlying pavements. Chemical stabilisation is one of the most used approaches to treat the expansive clay subgrades. Cement, Lime and Fly ash are the most commonly used stabilisers, in which fly is cheaper and a by-product obtained from the coal power plant. This paper reviews fly ash stabilisation on various clay types, including low plasticity clays, high plasticity clays, silty clays, organic clays, and peats. The review begins with the properties of fly ash, followed by the characteristics of fly ash stabilised subgrades. The micro-level mechanism, physical, mechanical, and hydraulic characteristics of stabilised pavements are presented graphically for the Class C, and F fly ashes. The micro-level studies reveal that the pozzolanic reaction is stronger than the cation exchange during the fly ash stabilisation. The unconfined compressive strength (UCS), California bearing ratio (CBR) and resilient modulus (Mr) increased with the fly ash addition and curing time for most soft soils except peat clays. Based on the mechanical and hydraulic characteristics, using 15% class C fly ash with 7 days of curing is recommended for optimum performance. Although few research studies confirm that the leachate limit of stabilised soil is within the acceptable limit, further studies are required to investigate the uptake of heavy metals and other certain carcinogenic contaminants. This study will provide key information for researchers and Engineers on the selection of fly ash stabilisation measures for expansive subgrades.

Abstract
OBJECTIVE To compare different types of diabetic macular edema (DME) classified based on optical coherence tomography (OCT) for their responses to Conbercept injection and analyze the factors that affect the treatment responses. METHODS We retrospectively analyzed the clinical data of 65 patients (76 eyes) with DME diagnosed and treated with intravitreal injection of Conbercept (1+PRN) in our hospital from February, 2019 to February, 2021. According to OCT findings, DME in these patients was classified into cystic macular edema (CME; 28 eyes), serous retinal detachment (SRD; 33 eyes), and diffuse retinal thickening (DRT; 15 eyes). The best corrected visual acuity (BCVA) and central retinal thickness (CRT) were measured before and at 3 months after the first treatment. The baseline OCT characteristics of different types of DME were compared, and the correlation of these OCT characteristics with the treatment response to Conbercept was analyzed. RESULTS All the patients showed significant improvement of the BCVA 3 months after the treatment (P < 0.05). For all the 3 types of DME, the CRT at 3 months after the first treatment was significantly reduced as compared to the baseline (P < 0.05). The number of hyperreflective foci (HF) in the outer retina and the proportion of ellipsoid zone (EZ) interruption were the greatest in SRD group (P < 0.05). The baseline outer retinal HF was significantly correlated with the baseline CRT, CRT changes and CRT after treatment (all P < 0.05). The patients with baseline outer limiting membrane (ELM)/ EZ disruption had poorer baseline BCVA, greater baseline CRT, greater variation of CRT and poorer BCVA at 3 months after treatment (all P < 0.05). CONCLUSION For all the 3 types of DME, treatment with intravitreal injection of Conbercept can significantly improve the BCVA and CRT of the patients. DME of the SRD type has the best morphological response to Conbercept, while the DRT type has a relatively poor response. A greater number of HF at baseline may indicate a better morphological response to Conbercept treatment, and baseline ELM/EZ disruption may suggest a poor visual prognosis at 3 months after treatment.

Abstract
Abstract
Aim
The aim of this study is to investigate whether a disruption of proximal and/or distal tibio-fibular joint correlates to patient’s function and osteoarthritis.
Method
Retrospective analysis of 44 patients with lower limb bone defects treated by tibial corticotomy and distraction osteogenesis was conducted. Analysis of lower limb x-rays before surgery, immediately post-surgery and after frame removal permitted calculations of changes in tibial length and changes in fibula position relative to the tibia at the proximal and distal tibio-fibular joints. X-rays before and after treatment were also graded for osteoarthritis severity using Alhbäck's classification. Functional ability was scored using the American Orthopaedic Foot & Ankle Society (AOFAS) score and the Knee society score (KSS).

15 patients showed a decrease in the distance between fibular tip and distal tibia, 5 showed no change and 12 showed an increase at the end of the treatment. No statistical significant association was noted with KSS or AOFAS score (p > 0.05), however one patient with a large distance increase exhibited severe radiological exacerbation of knee osteoarthritis. The distal corticotomy group achieved significantly higher length of new bone (p < 0.001) and were more likely to have exacerbation of knee osteoarthritis (p < 0.05). Conversely, proximal corticotomy group were significantly more likely to show an exacerbation of ankle osteoarthritis (p < 0.05).
Conclusions
Attempts should be made not to disrupt the tibio-fibular joints during bone transport, but disruption does not necessarily correlate to poorer outcomes. Our results show that lengthening index reduces with larger bone defects, suggesting that radical debridement/resection may not negatively affect the healing index.

Abstract
This article provides comprehensive experimental data of two water-swelling materials, water swelling rubber (WSR) and water-swelling polyurethane (WSP). Swelling tests, Dynamic Mechanical Analyzer (DMA) and Scanning Electron Microscope (SEM) were performed. Sealing properties of WSR and WSP were characterized by the data of swelling ratios (Sw and Sa), storage moduli (E') and images of micro-damage morphologies. These data can be useful for the prediction of the long-term waterproof performance of water-swelling materials and provide reference for material selection. The data presented herein was used for the article, titled "Laboratory evaluation of long-term sealing behaviors of two water-swelling materials for shield tunnel gasket" [1].

Abstract
While knowledge of early embryo development and viability has continually increased, there is still a need for noninvasive methods to identify embryos with the highest chances of development to term when transferred. The most widely used technique, morphological assessment, is highly subjective and limited by personnel experience. Spent media from invitro culture could be used as a valuable noninvasive marker for embryo quality assessment. Raman spectroscopy has proven to be a powerful tool for identifying the molecular characteristics of spent culture media by measuring vibration of chemical bonds, allowing for metabolomic profiling of varying stages and quality of embryos. It is well documented that embryos produced through somatic cell nuclear transfer (SCNT) result in lower pregnancy rates and higher incidences of pregnancy loss when compared with embryos produced through IVF (Heyman et al. 2002 Biol. Reprod. 66, 1-13). This study was designed to examine differences in spent media between bovine embryos produced by IVF and SCNT. The SCNT embryos with a metabolomic profile more similar to IVF embryos may have a higher developmental competence. Bovine cumulus-oocyte complexes (COCs) were retrieved from abattoir-derived ovaries and matured for 21h in maturation medium. After IVM, COCs were either used for IVF or SCNT and cultured in 50μL droplets of synthetic oviductal fluid medium + fetal bovine serum in groups of 45 from Day 0-5. On Day 5, embryos that had reached morula stage were placed in individual droplets of 13μL of synthetic oviductal fluid + bovine serum albumin until Day 7. All embryos were cultured at 38.5°C and 5% CO2. On Day 7 embryos were assessed for developmental stage and quality and 10μL of medium from individual culture drops was collected for Raman spectroscopy. Samples were loaded on an MgF2 optical window, dried, and analysed using a 785nm near-infrared laser in the spectral range of 600 to 1800cm−1. Raw Raman data were first pre-processed by baseline correction (asymmetric least-squares smoothing) and normalization. Principal component analysis and partial least squares were then applied to reduce data dimensions. The score of the most significant principal components from principal component analysis and the optimum number of scores from partial least squares were used for linear discriminant analysis. Spent media samples from 4 SCNT embryos, 3 IVF embryos, and 3 empty media samples were analysed, with 50 spectra obtained from each sample. Preliminary data showed grouping of medium containing embryos developed to blastocyst from medium containing embryos arrested at morula or empty medium. We also saw grouping of medium containing SCNT embryos from medium containing IVF embryos within both the morula and blastocyst stage from empty medium. This shows evidence of metabolomic differences between embryos of different developmental potential and embryos produced by IVF and SCNT. Further investigation of the Raman profile of these groups can display specific differences in chemical components and help to identify candidate genes causing differing metabolism of these groups.

Abstract
UNLABELLED We conducted a phenome-wide Mendelian randomization analysis (MR-PheWAS) to survey health effects associated with high normal serum calcium. We found causal evidence for conditions related to renal function, bone and joint health, and cardiovascular risk. These conditions collectively suggest that tissue calcification may be a key mechanism through which serum calcium influences health. INTRODUCTION Calcium is essential for the normal functioning of the cardiovascular system, muscles, and nerves. In this MR-PheWAS study, we sought to capture the totality of health effects associated with high normal serum calcium. METHODS We used data from up to 337,535 UK Biobank participants, and tested for associations between calcium genetic score (calcium-GS) and 925 disease outcomes, with follow-up analyses using complementary MR methods. RESULTS Calcium-GS was robustly associated with serum calcium concentration (F statistics = 349). After multiple testing correction (P < 1.62E-4), we saw genetic evidence for an association between high serum calcium and urinary calculus (OR per 1 mg/dl 3.5, 95%CI 1.3-9.2), renal colic (9.1, 95%CI 2.5-33.5), and allergy/adverse effect of penicillin (2.2, 95%CI 1.5-3.3). Secondary analyses with independent replication from consortia meta-analyses suggested further effects on myocardial infarction and osteoarthrosis. CONCLUSION We found causal evidence for effects of high normal serum calcium with conditions related to renal function, bone and joint health, and cardiovascular risk, which may collectively reflect influences on tissue calcification and immune function.

Abstract
Abstract
Tumors that overexpress the MYC oncogene, including most receptor triple-negative breast cancers, frequently demonstrate aneuploidy, numerical chromosome alterations associated with highly aggressive cancers. Aneuploidy is also associated with rapid tumor evolution and poor patient outcome. We identify that MYC overexpression induces reversible defects in microtubule nucleation and mitotic spindle assembly, in TNBCs and other epithelial cells, promoting chromosome segregation defects, micronuclei and chromosomal instability (CIN). High TPX2 expression is permissive for mitotic spindle assembly and chromosome segregation in cells with MYC overexpression; whereas TPX2 depletion blocks mitotic progression, induces cell death and prevents tumor growth. Attenuating MYC expression reverses mitotic defects, even in established breast tumor cell lines, implicating an ongoing role for high MYC in the persistence of CIN in cancers. Our studies implicate the MYC oncogene as a regulator of spindle assembly and identify a new MYC-TPX2 synthetic-lethal interaction in TNBC that could represent a future therapeutic strategy in MYC-overexpressing cancers. Moreover, our studies suggest that blocking MYC activity can attenuate the emergence of CIN and tumor evolution.

Abstract
A single-multi-single mode (SMS) fiber structure with spiral microgroove, fabricated by femtosecond laser inscription has been proposed and successfully employed for refractive index (RI) sensing. The multimode interference in the SMS structure is effectively affected by the external perturbation due to the microgroove, which goes deep into the core of the multimode fiber (MMF). Experimental results show that this femtosecond-induced spiral micro-structured SMS (FISM-SMS) fiber structure exhibits a linear response to eternal liquid refractive index in a large RI range of 1.3373-1.4345. The maximum sensitivity of the structure can reach to 2144 nm/RIU and can be further improved by increasing the depth of the spiral micro-grooves.

Validation of combinatorial probe-anchor ligation-based sequencing as non-invasive prenatal test for trisomy at a central laboratory. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2017; 50:49-57.

Abstract
OBJECTIVE To evaluate the clinical validity of a new ultrahigh-throughput non-invasive prenatal test (NIPT) based on combinatorial probe-anchor ligation (cPAL) sequencing of cell-free fetal DNA (cffDNA) using centralized testing. METHODS Maternal plasma samples were obtained from 10 594 singleton pregnancies in high-risk populations at 20 centers in China, including 8155 that were collected retrospectively and 2439 prospectively. Fetal outcome data and karyotyping results were documented as gold standard and were double blinded during NIPT. The clinical performance of the ultrahigh-throughput sequencing method, cPAL, for NIPT was validated by evaluating its sensitivity, specificity and positive predictive value (PPV) in detecting trisomies 21, 18 and 13 as the centralized testing mode in the reference laboratory. To ensure stable and reproducible performance of centralized cPAL-based NIPT in detecting trisomies, a series of quality-control systems, including sequencing of two sets of artificial samples, were employed and evaluated. RESULTS Ten prospective cases were excluded from the study because of incomplete clinical data. Four prospective samples failed to generate a NIPT result due to assay failure, presenting a failure rate of 0.16% (4/2429). A total of 168 retrospective cases and 47 prospective cases had a positive NIPT result for trisomy, giving respective positive rates of 2.06% and 1.94%. Four false-positive and no false-positive cases were observed in the retrospective and prospective groups, respectively, resulting in PPV of 97.62% (95% CI, 94.02-99.35%) and 100% (95% CI, 92.45-100%), respectively. In the retrospective group, sensitivity and specificity were, respectively, 100% (95% CI, 97.07-100%) and 99.98% (95% CI, 99.94-100%) for trisomy 21, 100% (95% CI, 97.75-100%) and 99.98% (95% CI, 99.94-100%) for trisomy 18, and 100% (95% CI, 15.81-100%) and 100% (95% CI, 99.95-100%) for trisomy 13. In the prospective group, sensitivity and specificity were, respectively, 100% (95% CI, 90.75-100%) and 100% (95% CI, 99.85-100%) for trisomy 21, 100% (95% CI, 63.06-100%) and 100% (95% CI, 99.85-100%) for trisomy 18, and 100% (95% CI, 2.50-100%) and 100% (95% CI, 99.85-100%) for trisomy 13. CONCLUSION In this multicenter study with a full quality-control system, NIPT by centralized cPAL-based testing showed high stability and performance comparable to those of previous validation studies in high-risk populations.

Abstract
This study aimed to determine whether psychological factors affect health-related
quality of life (HRQL) and recovery of knee function in total knee replacement (TKR)
patients. A total of 119 TKR patients (male: 38; female: 81) completed the Beck
Anxiety Inventory (BAI), Beck Depression Inventory (BDI), State Trait Anxiety
Inventory (STAI), Eysenck Personality Questionnaire-revised (EPQR-S), Knee Society
Score (KSS), and HRQL (SF-36). At 1 and 6 months after surgery, anxiety, depression,
and KSS scores in TKR patients were significantly better compared with those
preoperatively (P<0.05). SF-36 scores at the sixth month after surgery were
significantly improved compared with preoperative scores (P<0.001). Preoperative
Physical Component Summary Scale (PCS) and Mental Component Summary Scale (MCS)
scores were negatively associated with extraversion (E score) (B=-0.986 and -0.967,
respectively, both P<0.05). Postoperative PCS and State Anxiety Inventory (SAI)
scores were negatively associated with neuroticism (N score; B=-0.137 and -0.991,
respectively, both P<0.05). Postoperative MCS, SAI, Trait Anxiety Inventory (TAI),
and BAI scores were also negatively associated with the N score (B=-0.367, -0.107,
-0.281, and -0.851, respectively, all P<0.05). The KSS function score at the sixth
month after surgery was negatively associated with TAI and N scores (B=-0.315 and
-0.532, respectively, both P<0.05), but positively associated with the E score
(B=0.215, P<0.05). The postoperative KSS joint score was positively associated
with postoperative PCS (B=0.356, P<0.05). In conclusion, for TKR patients, the
scores used for evaluating recovery of knee function and HRQL after 6 months are
inversely associated with the presence of negative emotions.

Abstract
Transition dynamics and mean shear flow generation in plasma interchange turbulence are explored in a flux-driven system that resembles the plasma edge region. The nonlinear evolution of the interchange mode shows two confinement regimes with different transport levels. Large amplitude oscillations in the phase space of turbulence intensity and mean flow energy are observed and investigated. Both clockwise and counterclockwise oscillations occur during the transition between the two regimes. The Reynolds stress gradients are shown to play a critical role in the generation of mean sheared flows in the edge region. Both the forward and back transitions are simulated self-consistently and a significant hysteresis is found.

Abstract
Infection with the protozoan parasite Toxoplasma gondii is widespread, and the organism can cause congenital infections in humans. The horizontal transmission of Toxoplasma is even more common than congenital. An effective vaccine strategy brings the prospect of improving Toxoplasma disease control. Rhoptry protein 5 (ROP5) and ROP7 are potential stimulators of humoral and cellular immune responses. In this study, we constructed a multi-antigenic DNA vaccine expressing ROP5 and ROP7 of T. gondii and compared the protective efficacy to single-gene vaccines and control groups. BALB/c mice were immunized intramuscularly three times. The levels of IgG antibodies and cytokines in mice immunized with the multi-antigenic DNA vaccine (pROP5/ROP7) were significantly higher than those in the control mice. Mice vaccinated with pROP5/ROP7 showed a longer survival time (16 days) than single-gene-immunized mice (11 and 12 days, respectively) or control mice (8 days) after a challenge with 1 × 10(4) tachyzoites of RH strain of T. gondii. Furthermore, after intragastric infection with 20 cysts of PRU strain of T. gondii, the number of brain cysts in mice immunized with pROP5/ROP7 was only 25% of the number in control mice. Our results showed that a DNA vaccine encoding ROP5 and ROP7 significantly enhanced protection against T. gondii challenge.
