ABSTRACT

OBJECTIVE: This study aimed to investigate the effect of parecoxib sodium combined with perioperative psychological nursing on postoperative pain in elderly patients with hip fractures. PATIENTS AND METHODS: 80 elderly patients with hip fractures who received surgical treatment in our hospital were selected as the research subjects. According to the different interventions received by the patients, they were divided into a control group (CG) (n=40) who received intravenous parecoxib sodium intervention before surgery, and an observation group (OG) (n=40) who received perioperative psychological nursing intervention in addition to the intervention received by the CG. The pain status, psychological status, hip joint function, daily living ability level, and quality of life of the two groups were compared. RESULTS: After surgery, the VAS score, SAS score and SDS score of the OG were lower than those of the CG (p < 0.05). After surgery, the Harris score of the OG was higher than that of the CG (p < 0.05). Before surgery, there was no significant difference in the Barthel index and SF-36 score between the two groups (p > 0.05). After surgery, the Barthel index and SF-36 scores of both groups showed a significant improvement compared to before surgery, and the scores in the OG were higher than those in the CG (p < 0.05). CONCLUSIONS: Perioperative psychological nursing combined with preemptive analgesia of parecoxib sodium has a significant positive effect on elderly patients with hip fractures after surgery. The combined nursing intervention can further alleviate postoperative pain, improve patients' psychological status, promote the recovery of hip joint function, and significantly improve the daily living ability and quality of life of patients. The combined intervention plan is worthy of clinical promotion and application.

ABSTRACT

BACKGROUND AND PURPOSE: An MRI of the fetus can enhance the identification of perinatal developmental disorders, which improves the accuracy of ultrasound. Manual MRI measurements require training, time, and intra-variability concerns. Pediatric neuroradiologists are also in short supply. Our purpose was developing a deep learning model and pipeline for automatically identifying anatomic landmarks on the pons and vermis in fetal brain MR imaging and suggesting suitable images for measuring the pons and vermis. MATERIALS AND METHODS: We retrospectively used 55 pregnant patients who underwent fetal brain MR imaging with a HASTE protocol. Pediatric neuroradiologists selected them for landmark annotation on sagittal single-shot T2-weighted images, and the clinically reliable method was used as the criterion standard for the measurement of the pons and vermis. A U-Net-based deep learning model was developed to automatically identify fetal brain anatomic landmarks, including the 2 anterior-posterior landmarks of the pons and 2 anterior-posterior and 2 superior-inferior landmarks of the vermis. Four-fold cross-validation was performed to test the accuracy of the model using randomly divided and sorted gestational age-divided data sets. A confidence score of model prediction was generated for each testing case. RESULTS: Overall, 85% of the testing results showed a ≥90% confidence, with a mean error of <2.22 mm, providing overall better estimation results with fewer errors and higher confidence scores. The anterior and posterior pons and anterior vermis showed better estimation (which means fewer errors in landmark localization) and accuracy and a higher confidence level than other landmarks. We also developed a graphic user interface for clinical use. CONCLUSIONS: This deep learning-facilitated pipeline practically shortens the time spent on selecting good-quality fetal brain images and performing anatomic measurements for radiologists.

ABSTRACT

In this study, we developed an automated workflow using a deep learning model (DL) to measure the lateral ventricle linearly in fetal brain MRI, which are subsequently classified into normal or ventriculomegaly, defined as a diameter wider than 10 mm at the level of the thalamus and choroid plexus. To accomplish this, we first trained a UNet-based deep learning model to segment the brain of a fetus into seven different tissue categories using a public dataset (FeTA 2022) consisting of fetal T2-weighted images. Then, an automatic workflow was developed to perform lateral ventricle measurement at the level of the thalamus and choroid plexus. The test dataset included 22 cases of normal and abnormal T2-weighted fetal brain MRIs. Measurements performed by our AI model were compared with manual measurements performed by a general radiologist and a neuroradiologist. The AI model correctly classified 95% of fetal brain MRI cases into normal or ventriculomegaly. It could measure the lateral ventricle diameter in 95% of cases with less than a 1.7 mm error. The average difference between measurements was 0.90 mm in AI vs. general radiologists and 0.82 mm in AI vs. neuroradiologists, which are comparable to the difference between the two radiologists, 0.51 mm. In addition, the AI model also enabled the researchers to create 3D-reconstructed images, which better represent real anatomy than 2D images. When a manual measurement is performed, it could also provide both the right and left ventricles in just one cut, instead of two. The measurement difference between the general radiologist and the algorithm (p = 0.9827), and between the neuroradiologist and the algorithm (p = 0.2378), was not statistically significant. In contrast, the difference between general radiologists vs. neuroradiologists was statistically significant (p = 0.0043). To the best of our knowledge, this is the first study that performs 2D linear measurement of ventriculomegaly with a 3D model based on an artificial intelligence approach. The paper presents a step-by-step approach for designing an AI model based on several radiological criteria. Overall, this study showed that AI can automatically calculate the lateral ventricle in fetal brain MRIs and accurately classify them as abnormal or normal.

ABSTRACT

Bees are important pollinators and are essential for the reproduction of many plants in natural and agricultural ecosystems. However, bees can have adverse ecological effects when introduced to areas outside of their native geographic ranges. Dozens of non-native bee species are currently found in North America and have raised concerns about their potential role in the decline of native bee populations. Osmia taurus Smith (Hymenoptera: Megachilidae) is a mason bee native to eastern Asia that was first reported in the United States in 2002. Since then, this species has rapidly expanded throughout the eastern part of North America. Here, we present a comprehensive review of the natural history of O. taurus, document its recent history of spread through the United States and Canada, and discuss the evidence suggesting its potential for invasiveness. In addition, we compare the biology and history of colonization of O. taurus to O. cornifrons (Radoszkowski), another non-native mason bee species now widespread in North America. We highlight gaps of knowledge and future research directions to better characterize the role of O. taurus in the decline of native Osmia spp. Panzer and the facilitation of invasive plant-pollinator mutualisms.

ABSTRACT

Objective: To evaluate the predictive value of a multiparametric cardiac magnetic resonance (CMR) approach for ventricular remodeling in ST-segment-elevation myocardial infarction (STEMI) patients with mildly reduced or preserved left ventricular ejection fraction (LVEF). Methods: This study is a prospective cohort study. STEMI patients with acute LVEF>40% after primary percutaneous coronary intervention (PCI) in Beijing Anzhen Hospital from October 2019 to September 2021 were enrolled. All patients received acute (3-7 days) and follow-up (3 months) CMR post-PCI. According to absence or presence of ventricular remodeling, patients were divided into ventricular remodeling group and non-ventricular remodeling group. Basic clinical characteristics and CMR indicators were analyzed and compared between the two groups. Logistic regression and receiver operating characteristic (ROC) curves were used to explore the predictive performance of CMR high-risk attributes for ventricular remodeling in STEMI patients with mildly reduced or preserved LVEF. The predictive value of combining multiple high-risk characteristics of CMR for ventricular remodeling was analyzed and compared with the traditional clinical risk factor model. Results: A total of 123 STEMI patients were enrolled (aged (57.1±11.1) years, 102 (82.9%) males). There were 97 cases (78.9%) patients in the non-ventricular remodeling group and 26 cases (21.1%) in the ventricular remodeling group. After adjustment for clinical risk factors, stroke volume<51.6 ml, global circumferential strain>-13.7%, infarct size>39.2%, microvascular obstruction>0.5%, and myocardial salvage index<43.9 were independently associated with ventricular remodeling in STEMI patients with mildly reduced or preserved LVEF. The incidence of ventricular remodeling increased with the increasing number of CMR high-risk attributes (P<0.01). The number of CMR high-risk attributes ≥3 was an independent predictor of adverse remodeling (adjusted OR=5.95, 95 CI%: 2.25-15.72, P<0.01) in STEMI patients with mildly reduced or preserved LVEF. Furthermore, the number of CMR high-risk attributes had incremental predictive value over baseline clinical risk factors (area under curve: 0.843 vs. 0.696, P<0.01). Conclusions: In STEMI patients with mild reduced or preserved LVEF, 5 CMR characteristics are associated with ventricular remodeling. The combination of ≥3 CMR high-risk characteristics is an independent predictor of ventricular remodeling, which has incremental predictive value beyond traditional risk factors in this patient cohort.

ABSTRACT

The clinical data of five cases of relapsed/refractory (R/R) Philadelphia chromosome-positive acute B-lymphocytic leukaemia (Ph+B-ALL) treated with Bcl-2 inhibitor venetoclax combined with tyrosine kinase inhibitor (TKI) and dexamethasone-containing low-dose chemotherapy regimen at Zhengzhou University Cancer Hospital were analyzed, and the efficacy and safety were evaluated. Ponatinib was used in two of the five patients with T315I mutation, and flumatinib was used in other three patients. The results showed that, of the four minimal residual disease (MRD) positive patients, three achieved complete molecular remission (CMR) in the short term and one was ineffective. Another patient with morphological recurrence reached CR in one month. The overall response rate was 80%. Treatment related adverse reactions included mild skin pigmentation, gastrointestinal reactions, fatigue, and grade Ⅰ-Ⅱ bone marrow suppression.

ABSTRACT

The precious rare edible fungus Morchella conica is popular worldwide for its rich nutrition, savory flavor, and varieties of bioactive components. Due to its high commercial, nutritional, and medicinal value, it has always been a hot spot. However, the molecular mechanism and endophytic bacterial communities in M. conica were poorly understood. In this study, we sequenced, assembled, and analyzed the genome of M. conica SH. Transcriptome analysis reveals significant differences between the mycelia and fruiting body. As shown in this study, 1,329 and 2,796 genes were specifically expressed in the mycelia and fruiting body, respectively. The Gene Ontology (GO) enrichment showed that RNA polymerase II transcription activity-related genes were enriched in the mycelium-specific gene cluster, and nucleotide binding-related genes were enriched in the fruiting body-specific gene cluster. Further analysis of differentially expressed genes in different development stages resulted in finding two groups with distinct expression patterns. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment displays that glycan degradation and ABC transporters were enriched in the group 1 with low expressed level in the mycelia, while taurine and hypotaurine metabolismand tyrosine metabolism-related genes were significantly enriched in the group 2 with high expressed level in mycelia. Moreover, a dynamic shift of bacterial communities in the developing fruiting body was detected by 16S rRNA sequencing, and co-expression analysis suggested that bacterial communities might play an important role in regulating gene expression. Taken together, our study provided a better understanding of the molecular biology of M. conica SH and direction for future research on artificial cultivation.

ABSTRACT

A potential driver of pollinator declines that has been hypothesized but seldom documented is the introduction of exotic pollinator species. International trade often involves movement of many insect pollinators, especially bees, beyond their natural range. For agricultural purposes or by inadvertent cargo shipment, bee species successfully establishing in new ranges could compete with native bees for food and nesting resources. In the Mid-Atlantic United States, two Asian species of mason bee (Osmia taurus and O. cornifrons) have become recently established. Using pan-trap records from the Mid-Atlantic US, we examined catch abundance of two exotic and six native Osmia species over the span of fifteen years (2003-2017) to estimate abundance changes. All native species showed substantial annual declines, resulting in cumulative catch losses ranging 76-91% since 2003. Exotic species fared much better, with O. cornifrons stable and O. taurus increasing by 800% since 2003. We characterize the areas of niche overlap that may lead to competition between native and exotic species of Osmia, and we discuss how disease spillover and enemy release in this system may result in the patterns we document.

ABSTRACT

Objective: To investigate the efficacy and side effects of anti-CD19 CAR-T cell bridging to allogeneic hematopoietic stem cell transplantation (allo-HSCT) regimen for refractory B-lymphoblastic leukemia. Methods: 10 patients with refractory B-lymphoblastic leukemia with minimal residual disease (MRD) negative after anti-CD19 CAR-T cell treatment, then bridging to allo-HSCT from November 2017 to March 2019 in the Affiliated Cancer Hospital of Zhengzhou University were retrospectively analyzed. Results: ①Among 10 patients, 5 were males and 5 females, with a median age of 23.6 (10-31) years. 9 patients were diagnosed refractory acute lymphoblastic leukemia and the other one was chronic lymphoblastic leukemia. 10 patients reached MRD negative 30 days after anti-CD19 CAR-T cell. ②The donors were identical sibling (2 cases) and haploidentical family member (8 cases) . The median time from MRD negative after CAR-T treatment to transplantation were 32.5 (20-60) days. ③10 patients obtained complete haploidentical engraftment. The median time of neutrophil implantation was 15 (15-21) days, and 19 (17-30) days of platelet implantation. ④ After conditioning, no hepatic venoocclusive disease and hemorrhagic cystitis occurred. One patient had leakage syndrome and got improved after intervention such as limited water entry, albumin supplementation and diuresis. 8 (80%) patients had fever, 2 cases experienced acute graft-versus-host disease (GVHD) grade Ⅱ, 1 case with aGVHD grade Ⅲ. Among 9 survivals, localized chronic GVHD occurred in 8 patients. ⑤The median follow-up was 262 (150-540) days and the estimated 1-years overall survivaln (OS) and disease free survival (DFS) were (90.0±1.0) % and (85.7±1.3) %, respectively. Conclusion: Anti-CD19 CAR-T cell bridging to allo-HSCT regimen is a feasible choice with favorable outcome for refractory B-lymphoblastic leukemia.

ABSTRACT

Objective: To investigate related factors for microalbuminuria in adult type 1 diabetes (T1D) patients of short disease duration (less than 5 years), and provide evidence for prevention of early diabetic kidney disease in this population. Methods: All adult patients enrolled in the Guangdong T1D translational medicine study between 2011 and 2017 with a disease duration of less than 5 years were included in this analysis. At enrollment, patients' demographic and clinical data were documented, and blood and urine samples were collected for the measurements of blood lipids, glycated hemoglobin A1c and urine albuminuria. Insulin resistance was evaluated by estimated glucose disposal rate (eGDR). Patients were categorized into groups based on urine albumin creatitine ratio (UACR): normoalbuminuric group (UACR<30 mg/g) and microalbuminuric group (UACR≥30 mg/g). Stepwise multivariate linear regression analysis was used to analyze risk factors for microalbuminuria in adult T1D patients of short disease duration. Results: A total of 384 patients were included in this analysis, and 51.3% (197/384) of which was female. The onset age of patients was (24.6±12.5) years, with a disease duration of 2.1(0.6, 3.5) years, body mass index of (19.8±3.2) kg/m(2), waist hip ratio of 0.85±0.21, and glycated hemoglobin A1c of (9.8±3.3)% at enrollment. Microalbuminuria occurred in 62 patients (16.1%). Multivariate linear analysis showed that higher glycated hemoglobin A1c, higher systolic blood pressure and more severe insulin resistance were related factors for microalbuminuria (t=2.322, 2.868 and -2.373, respectively, all P<0.05). Conclusions: Microalbuminuria was not rare in adult T1D patients of short disease duration. Inadequate glycemic control and insulin resistance were independent related factors for microalbuminuria in this population.

ABSTRACT

Objective: To evaluate the efficacy and safety of mesenchymal stem cells in allogeneic hematopoietic stem cell transplantation for patients with refractory severe aplastic anemia (R-SAA) . Method: The clinical data of 25 R-SAA patients receiving co-transplantation of mesenchymal stem cells combined with peripheral blood stem cells from sibling donors (10 cases) and unrelated donors (15 cases) from March 2010 to July 2018 in Zhengzhou University Affiliated Tumor Hospital were retrospectively analyzed. Antithymocyte globulin (ATG) treatment was ineffective/relapsed in 11 cases, and cyclosporine (CsA) treatment ineffective/relapsed in 14 cases. Results: There were 13 male and 12 female among these patients. One patient had a primary graft failure, one patient had a poorly engraftment of platelets, and the remaining 23 patients achieved hematopoietic engraftment. The median time of granulocyte engraftment was 12.5 (10-23) days and 15 (11-25) days for megakaryocyte. Incidences of grade Ⅰ/Ⅱ acute graft-versus-host disease (aGVHD) and chronic graft-versus-host disease (cGVHD) were 37.5% (9/24) and 21.7% (5/23) , respectively. There was no severe GVHD and no severe complications that related to transplantation. 21 of 25 (84%) patients were alive with a median follow-up of 22.9 (1.6-107.8) months. The 5-year overall survival rate after transplantation was (83.6±7.5) %. Conclusion: The combination of mesenchymal stem cells is reliable and safe in the treatment of R-SAA in peripheral blood stem cell transplantation of unrelated donors and sibling donors, which could significantly reduce the incidence of GVHD and severe transplantation-related complications.

ABSTRACT

Objective: To improve the knowledge and experience of ibrutinib combined with CAR-T cells in the treatment of high-risk chronic lymphoblastic leukemia (CLL) patients or small lymphocytic lymphoma (SLL) with TP53 gene aberration. Methods: One case of del (17p) CLL patients with BCL-2 inhibitor resistance was treated with ibrutinib combined with CAR-T cells, successfully bridged to allogeneic hematopoietic stem cell transplantation (allo-HSCT) , and the relative literatures were reviewed. Results: The patient was a young female with superficial lymph node enlarging at the beginning of the onset. Lymph node biopsy was confirmed as small lymphocytic lymphoma (SLL) without del (17p) . The disease progressed rapidly to CLL/SLL with del (17p) and bone marrow hematopoietic failure 2 years later. Firstly, the patient was treated with BCL-2 inhibitor (Venetoclax) , and the enlarged lymph nodes shrank significantly 2 months later. After 3 months, the disease progressed rapidly. The spleen was enlarged to 16 cm below the ribs, the neck lymph nodes was rapidly enlarged, and the superior vena cava syndrome appeared, which were mainly attributed to venetoclax resistance; so BTK inhibitor (ibrutinib) was used continuously after venetoclax discontinuation. Partial remission (PR) was achieved without lymphocytosis after 2 months, then ibrutinib was combined with CAR-T cells targeting CD19 antigen. Grade 1 of cytokine release syndrome (CRS) appeared after CAR-T cells infusion, and the complete remission (CR) was achieved after 1 month both in bone marrow and peripheral blood, with minimal residual disease (MRD) negative, then bridging allo-HSCT after 2 months of combined therapy. Conclusion: CLL/SLL patients with TP53 aberration have poor prognosis because of rapid progression, drug resistance, etc. Ibrutinib combined with CAR-T cell therapy can quickly achieved complete remission.
