Background: It is difficult to evaluate whether monitoring serum sFlt-1, PlGF, or sFlt-1/PlGF in pregnant women who are suspected of having PE can significantly shorten the PE diagnosis time. Objectives: To estimate the accuracy of sFlt-1, PlGF and sFlt-1/PlGF in preeclampsia prediction. Search Strategy: Databases including PubMed, Web of Science, Medline, CNKI, SinoMed, VIP Journal, and Wanfang Data were searched for eligible studies published until October 7, 2020. Selection Criteria: The research subjects were pregnant women with or without PE. The research types were case-control studies and cohort studies. This was an original study involving the detection of at least one of the following in the blood, serum or plasma: sFlt-1, PlGF, and sFlt-1/PlGF. Data Collection and Analysis: Meta-Disc 1.4 was employed, using the Sen, Spe, PLR, NLR, and DOR to plot SROC, and subgroup analysis and meta-regression were conducted. Main Results: Meta-analysis showed that for sFlt, PlGF and sFlt-1/PlGF, the Sen was 0.811 (95% CI: 0.783-0.837), 0.735 (95% CI: 0.713–0.757), and 0.779 (95% CI: 0.763–0.795), respectively; the Spe was 0.786 (95% CI: 0.769-0.802), 0.731 (95% CI: 0.721-0.741),and 0.885 (95% CI: 0.881-0.889), respectively. Conclusions: The sFlt-1/PlGF ratio showed better predictive performance for preeclampsia than sFlt-1 or PlGF alone. However, the predictive value of the latter two cannot be ignored.

Long-term follow-up data in Guinea support WHO recommendation on duration of bladder catheterization after the surgical repair of simple obstetric urinary fistula

Background: Scylla paramamosain frequently elicits IgE-mediated type-I hypersensitivity reactions. Molecular candidates for crab allergen-specific immunotherapy (AIT) have not been studied previously. This study aimed to investigate the effects of conformational and linear epitopes on immunoreactivity, and to produce hypo-immunoreactive derivatives for crab myofibril allergens. Methods: We produced reduced and alkylated allergens (alkylation performed using iodoacetamide [IAA]) with destroyed conformational epitopes. We also produced mutant (mt) allergens with deleted or heat/digestion-treated linear epitopes. These allergens are collectively referred to here as derivatives. Structural changes in the derivatives were determined using circular dichroism and fluorescent probes, and the immunoreactivity of derivatives was analyzed by performing enzyme-linked immunosorbent assays (ELISAs) and basophil-activation tests (BATs). Results: Compared with wild-type allergens (wtALLERGENs), IAA-treated allergens had dramatically altered protein structures, whereas mutant allergens (mtALLERGENs) showed slight structural effects. ELISAs revealed the heterogeneous epitope-recognition patterns with derivatives among 29 crab-sensitive patients, of whom 13% and 62% recognized conformational and linear epitopes, respectively, whereas 25% recognized both epitope types to the same extent. mtALLERGENs had lower immunoreactivity than IAA-treated wtALLERGENs, showing no intergroup difference versus IAA-treated mtALLERGENs. Furthermore, mtALLERGENs could not bind to IgE or induce basophil activation in some patients. Conclusions: Heat/digestion treatment of linear epitopes had a greater influence on immunoreactivity than their structural destruction. Conformational and linear epitopes were recognized in patient-specific crab myofibril allergens. Our results imply that hypo-immunoreactive derivatives of crab myofibril allergens that specifically lacked linear epitopes may serve as viable candidates for AIT in patients with crab allergies.

Purpose: The study aimed to design and propose an automatic annotation model of segmentation teeth in dental panoramic radiographs using deep-learning artificial intelligence (AI) algorithms. Methods: A total of 1183 anonymized panoramic radiographs were used to develop the AI model (CranioCatch, Eskisehir, Turkey) for an automatic annotation model of teeth and dental conditions including implant, crown, pontic, and filling in dental panoramic radiographs. U-Net implemented with PyTorch library was used for developing an automatic annotation model. The confusion matrix was used as a metric of the success of the AI model. Results: The sensitivity, precision, and F1-score values for teeth annotation at 70% intersection over union (IoU) value were 1, 0.9894, and 0.9947, respectively. At 50% IoU value, the sensitivity, precision, and F1-score values were found as 1, 1, 1, respectively. The sensitivity, precision, and F1-score values for dental condition annotation at 70% IoU value were 0.9963, 0.84, and 0.9115, respectively. At 50% IoU value, the sensitivity, precision, and F1-score values were found as 0.9963, 0.9446, 0.9698, respectively. Conclusion: To develop an artificial intelligence model for dental image classification, image segmentation, and object detection generally needs lots of labeled images. To overcome the struggles of manual annotation, the proposed annotation tool can be used to make it easier to increase the number of labeled data to further enhance the success of AI studies.

Solving the reproductive barriers of dairy cows has become one of the most critical factors determining the dairy industry’s development. Clinically, inflammation disease like endometritis is one of the leading causes in reducing dairy production’s financial viability. MiR-193 family can induce cells apoptosis and differentiation has been reported in various diseases. LGR4 plays a vital role in reproductive system development and immune system regulation, and it is closely related to animal reproductive function and cytokine regulation. In this study, we observed a negative relationship between miR-193a-3p and LGR4 expression level in both inflammatory tissues and cells, and the expression level of miR-193a-3p and LGR4 in bovine endometrial epithelial cells (BENDs) is regulated by lipopolysaccharide (LPS) stimulation time and dose-dependent. Subsequently, miR-193a-3p mimics and inhibitors were used to explore its functions in the inflammation response process, finding that overexpression of miR-193a-3p markedly increase the expression level of pro-inflammatory cytokines induced by LPS, such as IL-1β, IL-6 and TNF-α, while the group in which transfected inhibitor is on the contrary. Of note, immunofluorescence and western blotting results showed that miR-193a-3p enhances LPS-induced NF-κB p65 phosphorylation through targeting LGR4, whereas inhibiting miR-193a-3p could suppress the activation of NF-κB pathway significantly. In conclusion, our study firstly reported the mechanism by which miR-193a-3p targets LGR4 to elevate the inflammatory response in bovine endometrium injury, thereby implying that knockdown miR-193a-3p may lay the theoretical and practical basis for drug development of alleviating endometritis in dairy cows.

ABSTRACT Objective: To investigate the current status and influencing factors of evidence-based practice (EBP) with knowledge, attitude and practice (KAP) of ophthalmic nursing staffs in South China. Methods: Using a convenient sampling method, we selected 429 ophthalmic nursing staffs from 28 ophthalmology specialist hospitals or general hospitals in South China, and investigated their general information and implemented the evidence-based practice questionnaire (EBPQ). Results: The scores of EBP and KAP of ophthalmic nursing staffs in South China from high to low were as follows: practical attitude (4.85±1.07) points, practical behavior (4.42±1.14) points, practical knowledge and skills (4.30±0.65) points. The single factor analysis results showed that the first graduation degree, technical title, scientific research achievements, whether or not participate in EBP training, the frequency of reading literature at ordinary time, and whether or not participate in EBP project were the influencing factors of EBP level; the multi-factor analysis results showed that EBP attitude, EBP knowledge and skills, whether or not participate in EBP training were independent influencing factors of EBP. Conclusions: The ophthalmic nursing staffs in South China have a positive attitude towards EBP, however, their EBP knowledge, skills and behavioral capabilities need to be focused and improved. The ophthalmic nursing administrators should fully master the factors affecting the implementation of EBP, and take effective intervention measurement to improve the EBP abilities of ophthalmic nursing staffs, and promote the development of EBP in ophthalmology specialty.

Abstract Backgrounds and purpose: Anti-TNF therapy have gained great success in autoimmune disease. However, insufficient efficacy and safety of high dosage anti-TNF agents are exposed in amounts of clinical cases. Aiming at improving therapeutic of anti-TNF therapy, an anti-TNF nanobody V19 and combination therapy with PGE2 was introduced. Experimental Approach: DSS-induced colitis mice was used for evaluating therapeutic effect of V19 and combination therapy. Variation of Treg/Th17 balance was raised as the criterion for comparing therapeutic with combination therapy and mono-therapy. Key Results: V19 expressed by Escherichia. coil showed therapeutic effect on DSS-induced colitis mice by inducing the increase of treg via up-regulating tm-TNF-α and TNFR2 in peripheral blood. However, cell apoptosis (treg, Dendritic Cells and CD8 T cells) was induced in peripheral blood under high dose of V19 accompanied with up-regulated tm-TNF-α. Besides, Th17 cells in colons from DSS-induced mice were induced by V19 accompanied with up-regulation of IL-6. Combination therapy presented better therapeutic effect than mono-therapy. After combination therapy, Th17 cells were significantly decreased in colons and vitro assay demonstrated that PGE2 reduced Th17 cells by down-regulating IL-6 in colons via EP4. Although PGE2 showed no influence on cell apoptosis and can not induce treg generation, it enhanced the ability of V19 in inducing treg by up-regulating TNFR2 via EP4 in peripheral blood. Conclusion: This combination therapy presents good clinical significance that combination of PGE2 can expand drug delivery window and enhanced therapeutic effect during the anti-TNF clinical treatment.

Standard models of speciation assume strictly dichotomous genealogies in which a species, the ancestor, is replaced by two offspring species. The reality is more complex: plant species can evolve from other species via isolation when genetic drift exceeds gene flow; lineage mixing can give rise to new species (hybrid taxa such as nothospecies and allopolyploids). The multi-copy, potentially multi-locus 5S rDNA is one of few gene regions conserving signal from dichotomous and reticulate evolutionary processes down to the level of intra-genomic recombination. Here, we provide the first high-throughput sequencing (HTS) 5S intergenic spacer (5S-IGS) data for a lineage of wind-pollinated subtropical to temperate trees, the Fagus crenata – F. sylvatica s.l. lineage, and its distant relative F. japonica. The observed 4,963 unique 5S-IGS variants reflect a long history of repeated incomplete lineage sorting and lineage mixing since the early Cenozoic of two or more paralogous-homoeologous 5S rDNA lineages. Extant species of Fagus are genetic mosaics and, at least to some part, of hybrid origin.

Covalent organic frameworks (COFs) have received considerable attention in molecular separation due to their tunable structures. However, how to determine the optimal number of layers for a COF is lack of theoretical guidance while considering tradeoff effect between water flux and rejection. Herein, the transport behavior of water and ions as a function of layer number was investigated for multilayered TpPa-(OMe)2 COFs with nonequilibrium molecular dynamics simulations. With an increase in the layer number from 2 to 6, the ion rejection was enhanced from 50% to nearly 90%. We attributed this phenomenon to the dehydration of ions entering the pore opening and a stronger interaction of Mg2+ than water with the internal groups of the COFs. Our data suggests that an optimal number of TpPa-(OMe)2 layers is 6. Under these conditions the COFs exhibited 90% MgCl2 rejection, whereas water permeance is 2 orders of magnitude higher than commercial nanofiltration membranes.

Placenta increta manifesting as unusual cervical mass after first trimester dilatation and curettage, managed by laparoscopy: A case report

Objective: To determine the relationship between lipid profile and risks of adverse pregnancy outcomes in pre-pregnant underweight women. Design: This study was part of an ongoing cohort study which Chinese gravidas delivered from January 2015 to December 2016. Setting: Pre-pregnant body mass index (pre-BMI) was classified into underweight (<18.5 kg/m2)， normal weight (18.5-22.9 kg/m2) and overweight/obesity (≥23 kg/m2). Population: There’re 1203 underweight- women, 3281 normal-weight women and 1209 overweight women met the criteria. Methods: Data of 6233 women and medical information including lipid concentrations, pregnancy complications, pregnancy and perinatal outcomes were analyzed. Results: The proportion of underweight women 19.2% and overweight/obese women19.4% was similar in South China. Serum TC level of underweight women was significantly higher than overweight/obese women (p < 0.001). After adjusting for maternal age, underweight women with high TC level had significantly higher occurrence of LGA [OR=2.24, 95%CI (1.08, 4.63)], and lower occurrence of SGA [OR=0.71, 95%CI (0.59, 0.85)], while there were no significant associations between TC and LGA or SGA in other groups. Conclusion: Underweight women with high TC had higher occurrence of LGA, while there was no association between TC levels and LGA in normal and overweight/obese women. Thus, we should recommend underweight women to manage the lipid.

Background: A significant portion of COVID-19 sufferers have asthma. The impacts of asthma on COVID-19 progression are still unclear but a modifying effect is plausible as respiratory viruses are acknowledged to be an important trigger for asthma exacerbations and a different, potentially type-2 biased, immune response might occur. In this study, we compared the blood circulating cytokine response to COVID-19 infection in patients with and without asthma. Methods: Plasma samples and clinical information were collected from 80 patients with mild (25), severe (36) or critical (19) COVID-19 and 29 healthy subjects at the John Radcliffe Hospital, Oxford, UK. The concentrations of 51 circulating proteins in the plasma samples were measured with Luminex and compared between groups. Results: Total 16 pre-existing asthma patients were found (3 in mild, 10 in severe, and 3 in critical COVID-19). The prevalence of asthma in COVID-19 severity groups did not suggest a clear correlation between asthma and COVID-19 severity. Within the same COVID-19 severity group, no differences were observed between patients with or without asthma on oxygen saturation, CRP, neutrophil counts, and length of hospital stay. The mortality in the COVID-19 patients with asthma (12.5%) was not higher than that in patients without asthma (17.2%). No significant difference was found between asthmatic and non-asthmatic in circulating cytokine response in different COVID-19 severity groups, including the cytokines strongly implicated in COVID-19 such as CXCL10, IL-6, CCL2, and IL-8. Conclusions: Pre-existing asthma was not associated with an enhanced cytokine response after COVID-19 infection, disease severity or mortality.

Aim The aim of this study was to investigate if children treated for pilocytric astrocytoma in the posterior fossa had late complications affecting cognition, language and learning. Methods This descriptive single-centre study includes 8 children and 12 adults treated as children for pilocytic astrocytoma in the posterior fossa, with a mean follow-up time of 12.4 (range 5-19) years. Well-established tests of intelligence, executive, language and academic function were used. Results Intelligence tests showed average results compared with norms. Five patients scored <-1 SD (70-84) and 3 low average (85-92) on full scale IQ. The patients scored average on subtests regarding executive function, except for significantly lower results in inhibition/switching (p= 0.004). In Rey complex figure test half of the patients scored below – 1 SD. Language tests were normal except for significantly lower results in naming ability (p=0.049) and in inference (p=0.046). In academic tests, results were average, except for significantly lower results in reading speed (p=0.024). Patients with learning difficulties performed worse in the tests. Conclusions The patients functional outcome was favourable but, a not-negligible part of the patients displayed neurocognitive difficulties as revealed by extensive neuro-cognitive and academic testing. Thus it is important to identify those in need of more thorough cognitive and pedagogic follow-up programs, including school interventions.

Introduction: The coronavirus 2019 (COVID-19) pandemic has demanded care changes for patients with chronic disease. Patients with CF are considered at higher risk of developing severe manifestations in the case of SARS-CoV-2 infection, and a need for new ways of safer care delivery has been required to avoid transmission. Objectives: To assess the impact of the lockdown during the first wave of the COVID-19 pandemic and remote monitoring on patient’s health status and daily maintenance therapy in a middle-income resource setting. Methods: During the first wave of the pandemic period, we changed from regular clinic visits to telephone visit calls to monitor our patients’ health condition and adherence to physiotherapy and physical exercise. Results: A total of 120 patients or their caregivers have been contacted by telephone call visits over ten weeks. During this period, 38 patients (28.33%) were identified to have pulmonary exacerbation; 89.5% were prescribed oral antibiotics, 3% were hospitalized to get iv antibiotics and 8% of the patients presented other CF complications. Most of the patients did not change the frequency of the daily physiotherapy. Moreover, 71% of the patients who performed regular physical exercise changed the frequency and the type of exercise during the quarantine period. Interestingly, mean FEV1 and body weight increased significantly and after the lockdown period. Conclusions: During the COVID-19 pandemic, the implementation of telephone contact processes aiming for CF patients’ appropriate care is of great importance. Further studies are needed to evaluate patient outcomes when transitioning from face-to-face clinics to telemedicine clinics.

Background Bronchopulmonary dysplasia (BPD) is a chronic respiratory disease that occurs in premature infants and the prognosis is variable depending on the comorbidities including fibrosis, emphysema, or pulmonary hypertension (PH). We present a case of a 9-year-old girl who developed PH associated with severe BPD (BPD-PH) and underwent bilateral lung transplantation (BLTx). Case description A 9-year-old girl admitted to our department to undergo BLTx. She was born at 23 weeks and 4 days gestation with a weight of 507 grams. She received ventilation for the first 2 months and required further respiratory care due to repetitive, severe respiratory infections. She was diagnosed with BPD-PH at 6 months of age and oral administration of pulmonary vasodilators were initiated. She was registered as a lung transplant candidate at 4 years of age after the life-threatening exacerbation. Chest computed tomography (CT) revealed severe lung conditions with ground-glass opacities and emphysematous low-density areas in the upper and lower lobes. BLTx from a brain-dead male donor was performed. The pathological findings of her resected lung revealed saccular, hypoplastic lung with alveolar repair/regeneration and medial hypertrophy and muscularization of peripheral arteries. The postoperative course was mostly uneventful. She was free from oxygen administration and showed no signs of PH after 6 months of the surgery. Conclusion This is the first case report of BLTx in a pediatric, irreversible BPH-PH patient with detailed pathohistological findings and clinical examination. Lung transplantation is one of the treatment options for severe BPD-PH.

Abstract: Aims: The purpose of this study was to identify serologic and clinical factors in SARS-Coronavirus 2 (SARS-CoV-2) patients which may correlate and predict need for mechanical ventilation and mortality. Furthermore, we sought to determine if a diagnosis of heart failure and elevations in Pro B-Type Natriuretic Peptide (pro-BNP) predicted clinical endpoints. Methods: 135 patients age 18 or older admitted to Loma Linda University Medical Center with SARS-Co-2 between March 16, 2020 and June 8, 2020 were categorized by demographic data (age, race, and gender), clinical parameters (temperature, heart rate, blood pressure, and peak fraction of inspired oxygen (FiO2)), and serologic markers pro-BNP. A regression analysis was done to correlate need for mechanical ventilation and mortality. Results: In univariate analysis, elevated pro-BNP correlated with need for mechanical ventilation (p=0.006) and mortality (p=0.001). In multivariate analysis, elevated pro-BNP was significantly associated with requiring intubation (OR 4.5, p=0.03). Each year of age (OR 1.08, p=0.006) and unit of BMI (OR= 1.05, p=0.03) were significantly associated with increased mortality. In patients without a diagnosis of heart failure, average pro-BNP was elevated (1141.66 ng/dL) however it did not correlate with need for intubation or mortality. Conclusions and clinical implications: Coronavirus disease-19 (COVID-19) is associated with increased mortality and worse clinical outcomes in patients with heart failure. Despite a lack of heart failure diagnosis, elevated markers such as NT-Pro-BNP have been associated with increased mortality in COVID-19 hospitalized patients. Although no clear ‘cut-off’ has been described, our study findings suggest elevated pro-BNP may be a useful marker for disease severity and respiratory complications of COVID-19 patients with possible cardiac involvement. Similar to other single center findings, our study demonstrates worsened clinical outcomes for patients with advanced age and elevated body-mass index.

This paper deals with a free boundary problem for the Lotka-Volterra competition model with degenerate diffusion over a one dimensional habitat. We prove that the global existence and uniqueness of solution, the long time behavior of solution and criteria for spreading and vanishing.

This paper is concerned with the first initial and boundary value problem of a class of nonclassical diffusion equations in solids. We first establish uniform decay estimates which are independent of the viscosity coefficient and prove some new existence and uniqueness results for solutions of the problem under some appropriate conditions. Then we show that it has a global pullback attractor. In the periodic case, we point out that the pullback attractor is actually periodic and forward attracting; furthermore, the problem has at least a periodic solution.

In this paper, we first provide a refinement result for the abstract continuation theorem for k-set contractions. The new version of the theorem is equivalent to the usual one and it better adapts to study the existence of solutions for nonlinear differential equations. Then we discuss a new class of coupled system of implicit fractional boundary value problem. The nonlinear terms of equations involving perturbations, and the boundary conditions are constituted by periodic and anti-periodic boundary conditions. Based on the abstract continuation theorem for k-set contractions, an interesting existence result is obtained. Finally, an example is constructed for illustrating the application of our main results.

Two-dimensional numerical investigation is conducted for incompressible fluid flow around staggered square cylinders at different arrangements. The in-house code is firstly validated for flow around a single square cylinder by comparing the results with results present in literature and fair agreement is obtained. The calculations are carried out for several values of Reynolds numbers (Re) ranging from 1 to 120. Aerodynamic features, involving the lift (CL) and drag (CD) coefficients, are predicted and analyzed for three arrangements. Besides, the physical parameters and the flow pattern in the wake are presented by varying the Reynolds number. Sensitivity of the CL and CD values to the change in the arrangement of the square cylinders is analyzed. The numerical outcomes of the present study demonstrate that changing the arrangements of cylinders dramatically the fluctuation of the lift and drag coefficients values relatively to each square cylinder. Moreover, computation analysis reveals that the CD and CL evolutions depend significantly on the different cylinder combinations and the variation of Reynolds number as well.

Background and Purpose: A large number of GPCRs are potentially valuable drug targets but remain understudied. Many of these lack well-validated activating ligands and are considered “orphan” receptors, and G protein coupling profiles have not been defined for many orphan GPCRs. Here we asked if constitutive receptor activity can be used to determine G protein coupling profiles of orphan GPCRs. Experimental Approach: We monitored GDP-sensitive interactions (coupling) between 48 understudied orphan GPCRs and five G proteins (240 combinations) using bioluminescence resonance energy transfer (BRET). No activating ligands were used. Constitutive BRET between the same receptors and β-arrestins was also measured. Key Results: We found sufficient GDP-sensitive BRET to generate G protein coupling profiles for 22 of the 48 receptors we studied. Altogether we identified 48 coupled receptor-G protein pairs, many of which have not been described previously. Conclusion and Implications: We conclude that receptor-G protein complexes that form spontaneously in the absence of guanine nucleotides can be used to profile G protein coupling of constitutively active GPCRs. This approach may prove useful for studying G protein coupling of other GPCRs for which activating ligands are not available.

Background and Purpose Metabolic chambers are routinely used for urine collection in rodents. In mice, due to small urination volume, evaporation in the metabolic chambers distorts diuresis and urinalysis parameters. We have developed a new technique of chronic bladder catheterization enabling long-term accurate and contamination-free urine collection in awake male and female mice. The study was aimed to illustrate its validity for long-term monitoring of diuresis, pharmacological and pharmacokinetic applications. Experimental Approach Urine was collected in male and female mice implanted with bladder catheters or using the metabolic chambers for 30 days, at 1 h resolution to estimate diurnal variation or at 10 min resolution after water load, desmopressin, furosemide or phenol red administration. Key Results Urine recovery in the metabolic cages drops to 50 % at the typical murine urination volume. Daily diuresis in catheterized mice is more than twice higher as compared to the metabolic cages. The twofold differences in urine flow rate are preserved when the circadian variation of diuresis, the effects of furosemide, desmopressin and water load are estimated using the two techniques. Reliable pharmacokinetic curves for phenol red (90 % recovery) were obtained in catheterized mice. Urine osmolarity, urinalysis and microbiological parameters evidence higher quality of the catheter-collected urine. 30 days after the surgery catheters were patent and had minimal impact on the animals’ heath. Conclusion and Implications Bladder catheterization is a useful tool for pharmacological and toxicological studies that require urine collection in mice.

In this study, the fractional sine-Gordon model in the time-dependent variable domain using Caputo non-integer order basis derivative is presented. The main purpose is to utilize the adaptation of reproducing kernel Hilbert algorithm to construct pointwise numerical solution to variant forms of fractional sine-Gordon model in fullness of overdetermination Dirichlet boundary condition. Allocates theoretical requirements are employed to interpret pointwise numerical solutions to such fractional models on the space of Sobolev. In addendum, the convergence of the pointwise numerical algorithm and error estimates are promoted by global convergence treatises. This handling pointwise numerical solution depending on the orthogonalization Schmidt process that can be straightway carried out to generate Fourier expansion within a fast convergence rate. The soundness and powerfulness of the discussed algorithm are expounded by testing the solvability of a couple of time-fractional sine-Gordon models. Some schematic plots and tabulated results outcomes signalize that the algorithm procedure is accurate and convenient in the field of fractional sense. Ultimately, future remarks and concluding are acted with the most focused used references.
