RESUMO

PURPOSE: A large number of epidemiological studies have shown that myopia is a complex disease involving genetic, environmental, and behavioral factors. The purpose of this study was to explore the role of PAX6 gene methylation in myopia in Chinese adolescents. METHODS: Eighty junior high school students were divided into four groups based on their vision test results: mild myopia, moderate myopia, severe myopia, and non-myopia control. The methylation level of PAX6 gene promoter was detected by bisulfate pyrosequencing. RESULTS: The methylation level of PAX6 gene in myopia group (8.06% ± 1.43%) was slightly but significantly higher than that in non-myopia controls (7.26% ± 1.17%). In addition, PAX6 gene methylation levels presented a decreasing pattern along with the aggravation of myopia. Post-hoc analysis indicated significant inter-group differences for the mild myopia group and other groups (All p < .05). In the subgroup analysis by gender, the methylation level of PAX6 gene promoter in girls was higher than that in boys (p = .023). The ROC curves showed a high accuracy of PAX6 gene methylation to predict mild myopia (AUC (95% CI) = 0.828 (0.709-0.947), p < .001). CONCLUSIONS: The methylation of PAX6 gene might play a role in the onset and progression of myopia in Chinese adolescents. And this could potentially explore the potential molecular mechanisms of juvenile myopia in the future.

RESUMO

Based on the observed biological activity of 1,2,4-triazin-5-one derivatives and their cyclic analogues, a novel series of 7H-thiazolo[3,2-b]-1,2,4-triazin-7-one derivatives that contain ester moiety compounds 3a-3g, carboxylic acid moiety compounds 4a-4g and piperazine amide moiety compounds 5a-5k at position-3 of the thiazolotriazinone scaffold were synthesized. The intermolecular cyclization occurred regioselectively at N2-position of 1,2,4-triazine ring was characterized by X-ray single-crystal diffraction analysis. The in vitro biological activities of the target compounds were assayed against some bacterial strains. Compared with ciprofloxacin, compounds 3g and 4g exhibited more excellent antibacterial activity, especially the activity against Staphylococcus aureus and Escherichia coli, showing that the fluorine at the para position of the benzyl group would be the best choice. In addition, compounds 4e-4g with carboxylic acid moiety can enhance the antibacterial activity. Compounds 5g-5k containing bulky 1-(substituted phenyl)piperazine moiety were found with slightly less biological activity. Similar to ciprofloxacin, the docking result of target compounds with DNA topoisomerase II indicates the carboxyl group of the target compounds with carboxylic acid moiety has a crucial salt bridge interaction with Mg2+ in the protein.

RESUMO

OBJECTIVE: To compare the efficacy of laparoscopy versus laparotomy in the treatment of transverse colon cancer. METHODS: Data from 100 patients with transverse colon cancer treated in our hospital from January 2018 to December 2020 were retrospectively analyzed in this study. According to the treatment methods, these patients were assigned into two groups: a laparotomy group (n=50) and a laparoscopy group (n=50). The intraoperative parameters, postoperative recovery, incidences of complications, postoperative pain, quality of life (QoL) score, postoperative serum inflammatory cytokine (hs-CRP, TNF-α, and IL-6) levels, and prognostic nutritional index (PNI) were analyzed and compared between the two groups. RESULTS: There was no significant difference in number of resected lymph nodes between the two groups. The operation time and intraoperative bleeding in the laparoscopy group were significantly less than those in the laparotomy group (P<0.05). The hospital stay, duration of gastrointestinal function recovery, and time of first postoperative flatus in the laparoscopy group were significantly shorter than those in the laparotomy group (all P<0.001). Moreover, the incidence of overall complications in the laparoscopy group was significantly lower than that in the laparotomy group (P<0.05). Compared with those in the laparotomy group, the VAS score was obviously lower and the QoL score was significantly higher in the laparoscopy group (all P<0.001). Patients in the laparoscopy group exhibited lower levels of postoperative hs-CRP, TNF-α and IL-6 in contrast to those in the laparotomy group (P<0.05). In additional, there was no significant difference in the PNI level before surgery between two groups. After surgery, the PNI level in the laparoscopy group was obviously higher than that in the laparotomy group (P<0.001). CONCLUSION: Laparoscopy is superior to laparotomy in treatment of transverse colon cancer through achieving better intraoperative outcomes, promoting postoperative recovery, reducing the incidence of complications and inflammatory reactions, alleviating postoperative pain, and improving therapeutic effects.

RESUMO

Objective: The effect of passive smoking exposure on the risk of type 2 diabetes has not been systematically studied. A meta-analysis was conducted to assess the association between passive smoking exposure and the risk of diabetes. Methods: We searched three major databases up to 31 October 2022 to identify relevant prospective cohort studies on the association between passive smoking and the risk of type 2 diabetes. The pooled relative risk (RR) and 95% confidence interval (CI) for the association between passive smoking exposure and the risk of type 2 diabetes were analyzed using a fixed-effect model. Results: Ten prospective cohort studies were included in this meta-analysis, with a total of 251,620 participants involved. The pooled RR showed a significantly positive association between nonsmokers exposed to passive smoking and type 2 diabetes as compared to non-smokers who were not exposed to passive smoking [RR = 1.27; 95% CI (1.19, 1.36); p < 0.001]. Sensitivity analysis indicated that the pooled RR was not substantially affected by any of the individual studies. Conclusion: Exposure to passive smoking increases the risk of type 2 diabetes. This study may have a positive effect on the prevention of type 2 diabetes. Systematic review registration: https://www.crd.york.ac.uk/PROSPERO/, identifier CRD42023372532.

RESUMO

OBJECTIVE: To investigate the application effect of the county medical community Hospital-Community health service organization-Home (HCH) model in nutritional management of patients with advanced gastrointestinal cancer after surgery. METHODS: This is a retrospective study. A total of 100 postoperative malnutrition patients with advanced gastrointestinal malignant tumors admitted to Lanxi People's Hospital from January 2022 to August 2022 were selected as subjects. All patients were divided into an observation group (n=50) or control group (n=50) according to the different methods of intervention. Patients in the observation group underwent care according to our county medical community HCH model, while those in the control group received routine perioperative nutrition management. The nutritional risk screening scores (NRS2002), Patient-Generated Subjective Global Assessment (PG-SGA) scores, body mass index (BMI), triceps skinfold thickness (TSF), upper arm circumference (AC); a well as levels of serum albumin (ALB), prealbumin (PA), transferrin (TRF), retinol binding protein (RBP), creatinine (Cr) and Free fatty acid (FFA); levels of immunoglobulin G (IgG), immunoglobulin M (IgM) and immunoglobulin A (IgA); and the levels of sodium (Na+), potassium (K+), calcium (Ca+) and lactic acid, and quality of life were recorded and compared between two groups. RESULTS: Compared with those before intervention, NRS2002 scores, PG-SGA score, BMI, TSF and AC after intervention were significantly improved in both groups. Compared with those after intervention in the control group, the NRS2002 score, PG-SGA score, BMI, TSF and AC of the patients in the observation group were significantly improved (all P<0.001). Compared with those before intervention, the levels of ALB, PA, TRF, RBP, Cr, FFA, IgG, IgM and IgA in the two groups were significantly higher after intervention. The levels of ALB, PA, TRF, RBP, Cr, FFA, IgG, IgM and IgA after intervention in the observation group were significantly higher than those in the control group (all P<0.05). Compared with those before management, the levels of Na+, K+ and lactic acid in the two groups were significantly decreased and the level of Ca+ was significantly increased after intervention. Compared with those after intervention in the control group, the patients in the observation group had significantly lower levels of Na+, K+ and lactic acid, and higher levels of Ca+ (all P<0.05). Compared with those before intervention, the scores of mental status, appetite, sleep quality, daily life and family understanding and cooperation in patients from the two groups after intervention were significantly higher. Compared with those after intervention in the control group, the patients in the observation group had significantly higher scores of life quality (P<0.05). CONCLUSION: The county medical community HCH model has a good effect in the nutritional management of patients with advanced gastrointestinal cancer surgery. The HCH model can effectively improve the nutritional status, enhance the immune function, and increase the quality of life. Thus it is worthy of clinical application.

RESUMO

Per- and polyfluoroalkyl substances (PFASs) are a family of highly fluorinated aliphatic substances widely used in industrial and commercial applications. This study aims to determine the inhibition of PFASs towards sulfotransferases (SULTs) activity, and trying to explain the toxicity mechanism of PFASs. In vitro recombinant SULTs-catalyzed sulfation of p-nitrophenol (PNP) was utilized as a probe reaction. The incubation system was consisted of PFASs, SULTs, PNP, 3'-phosphoadenosine-5'-phosphosulfate, MgCl2 and Tris-HCl buffer. Ultra-performance liquid chromatography was employed for analysis of the metabolites. All tested PFASs showed inhibition towards SULTs. The longer the carbon chain length of the PFASs terminated with -COOH, the higher is its capability of inhibiting SULT1A3. PFASs with -SO3H had a relatively higher ability to inhibit SULT1A3 activity than those with -COOH, -I and -OH. The inhibition kinetic parameter was 2.16 and 1.42 µM for PFOS-SULT1A1, PFTA-SULT1B1. In vitro in vivo extrapolation showed that the concentration of PFOS and PFTA in human matrices might be higher than the threshold for inducing inhibition of SULTs. Therefore, PFASs could interfere with the metabolic pathways catalyzed by SULTs in vivo. All these results will help to understand the toxicity of PFASs from the perspective of metabolism.

RESUMO

BACKGROUND & AIMS: Mild and moderate dysplasia are major premalignant lesions of esophageal squamous cell carcinoma (ESCC); however, evidence of the progression risk in patients with these conditions is extremely limited. We aimed to assess the incidence and risk factors for advanced neoplasia in patients with mild-moderate dysplasia. METHODS: This prospective cohort study included patients with mild-moderate dysplasia from 9 regions in rural China. These patients were identified from a community-based ESCC screening program conducted between 2010 and 2016 and were offered endoscopic surveillance until December 2021. We estimated the incidence of advanced esophageal neoplasia, including severe dysplasia, carcinoma in situ, or ESCC, and identified potential risk factors using the Cox regression model. RESULTS: The 1183 patients with mild-moderate dysplasia were followed up over a period of 6.95 years. During follow-up evaluation, 88 patients progressed to advanced neoplasia (7.44%), with an incidence rate of 10.44 per 1000 person-years. The median interval from the progression of mild-moderate dysplasia to advanced neoplasia was 2.39 years (interquartile range, 1.58-4.32 y). A total of 74.47% of patients with mild-moderate dysplasia experienced regression to nondysplasia, and 18.09% showed no lesion progression. Patients with mild-moderate dysplasia who had a family history of esophageal cancer and were age 55 years and older showed 97% higher advanced neoplasia yields than all patients with mild-moderate dysplasia. CONCLUSIONS: In a country with a high incidence of ESCC, patients with mild-moderate dysplasia showed an overall risk of advanced neoplasia progression of 1.04% per year. Patients with mild-moderate dysplasia would be recommended for endoscopic surveillance during the first 2 to 3 years.

RESUMO

BACKGROUND: The postoperative length of hospital stay (PLOS) is an important indicator of surgical quality. We identified perioperative factors that affect prolonged PLOS (PPLOS) after laparoscopic colorectal cancer resection, which is the preferred surgical approach for colorectal cancer, the third most common cancer. METHODS: This study was a secondary analysis of a randomized trial (clinicaltrials.gov ID: NCT03160144) that included 280 patients who underwent laparoscopic colorectal cancer resection. The primary outcome was a PPLOS, defined as a PLOS that was longer than the median PLOS. Baseline, anesthetic, surgical, and postoperative management factors were included in the univariate and multivariate analyses to identify factors influencing PPLOS. RESULTS: The median PLOS was 10 days, and 117 patients had a PPLOS. We identified six influencing factors for PPLOS: preoperative pulse oxygen saturation < 96% (odds ratio [OR], 3.09 [95% confidence interval (CI) 1.38-6.92]; P = 0.006), distant tumor metastasis (OR, 0.34 [95% CI 0.13-0.91]; P = 0.031), the Miles procedure or left hemicolectomy (OR, 4.51 [95% CI 1.67-12.18]; P = 0.003), perioperative surgical events (OR, 2.44 [95% CI 1.25-4.76]; P = 0.009), postoperative albumin infusion (OR, 2.19 [95% CI 1.14-4.19]; P = 0.018), and postoperative early ambulation (OR, 0.35 [95% CI 0.18-0.68]; P = 0.002). Further stratified analysis showed that postoperative albumin infusion might be a risk factor for PPLOS, even in patients with a preoperative albumin level < 40 g/L (OR, 2.29 [95% CI 0.98-5.34]; P = 0.056) or duration of surgery ≥ 3 h (OR, 2.52 [95% CI 1.08-5.87]; P = 0.032). CONCLUSIONS: A low preoperative pulse oximetry reading, complex surgical procedures, perioperative surgical events, and postoperative albumin infusion may be risk factors for PPLOS after laparoscopic colorectal cancer resection, whereas distant tumor metastasis and postoperative early ambulation might be protective factors. The association between postoperative albumin infusion, a modifiable factor, and PLOS or clinical outcomes warrants further investigation.

RESUMO

Importance: Surveillance endoscopy is recommended for patients with low-grade intraepithelial neoplasia (LGIN); high-quality evidence about the use of surveillance endoscopy and esophageal squamous cell carcinoma (ESCC) incidence in patients with LGIN is important but limited. Objective: To estimate long-term ESCC incidence rates in patients with LGIN and the association between surveillance endoscopy and ESCC incidence. Design, Setting, and Participants: This community-based, multicenter, prospective cohort study in 9 regions in rural China included patients with LGIN diagnosed by endoscopic screening between July 1, 2007, and December 31, 2016; all participants were followed up until December 31, 2021. Main Outcomes and Measures: The primary outcome was ESCC incidence. The ESCC standardized incidence ratio (SIR) was estimated using sex- and age-specific incidence in the general population of rural China in 2010 and hazard ratios (HRs) and 95% CIs were calculated using Cox proportional hazards models. Results: A total of 3258 patients with LGIN were included; 1772 (54.39%) were men, with a mean (SD) age of 58.21 (6.97) years. Among them, 1378 patients (42.30%) underwent at least 1 surveillance endoscopy (surveillance group) and 1880 (57.70%) did not undergo any surveillance endoscopy (nonsurveillance group). During the follow-up period (median, 7.96 years; IQR, 6.08-10.54 years), 170 ESCC cases were diagnosed, with a cumulative incidence of 6.28 per 1000 person-years. A higher incidence of ESCC (incidence rate, 7.07 per 1000 person-years) was observed in the nonsurveillance group than in the surveillance group (incidence rate, 5.14 per 1000 person-years). Patients with LGIN in the surveillance group had a lower SIR (SIR, 4.07; 95% CI, 1.13-10.34) than those in the nonsurveillance group (SIR, 5.65; 95% CI, 2.00-12.58); however, patients with LGIN in both groups had a higher risk of ESCC than the general population. Patients in the surveillance group had a 31% decreased risk of ESCC incidence (HR, 0.69; 95% CI, 0.50-0.95) compared with those in the nonsurveillance group, after adjusting for baseline risk factors. Conclusions and Relevance: In this prospective cohort study, patients with LGIN had a higher risk of developing ESCC than the general population, and endoscopic surveillance was associated with a decrease in ESCC incidence in these patients.

RESUMO

Bladder cancer (BC) is the most common urinary malignancy; however accurate diagnosis and prediction of recurrence after therapies remain elusive. This study aimed to develop a biosignature of immunotherapy-based responses using gene expression data. Publicly available BC datasets were collected, and machine learning (ML) approaches were applied to identify a novel biosignature to differentiate patient subgroups. Immune phenotyping of BC in the IMvigor210 dataset included three subtypes: inflamed, excluded, and desert immune. Immune phenotypes were analyzed with gene expressions using traditional but powerful classification methods such as random forests, Deep Neural Networks (DNN), Support Vector Machines (SVM) together with boosting and feature selection methods. Specifically, DNN yielded the highest area under the curve (AUC) with precision and recall (PR) curves and receiver operating characteristic (ROC) curves for each phenotype ([Formula: see text] and [Formula: see text], respectively) resulting in the identification of gene expression features useful for immune phenotype classification. Our results suggest significant potential to further develop and utilize machine learning algorithms for analysis of BC and its precaution. In conclusion, the findings from this study present a novel gene expression assay that can accurately discriminate BC patients from controls. Upon further validation in independent cohorts, this gene signature could be developed into a predictive test that can support clinical evaluation and patient care.

RESUMO

Buffalo is an important livestock species. Here, we present a comprehensive metagenomic survey of the microbial communities along the buffalo digestive tract. We analysed 695 samples covering eight different sites in three compartments (four-chambered stomach, intestine, and rectum). We mapped ~85% of the raw sequence reads to 4,960 strain-level metagenome-assembled genomes (MAGs) and 3,255 species-level MAGs, 90% of which appear to correspond to new species. In addition, we annotated over 5.8 million nonredundant proteins from the MAGs. In comparison with the rumen microbiome of cattle, the buffalo microbiota seems to present greater potential for fibre degradation and less potential for methane production. Our catalogue of microbial genomes and the encoded proteins provides insights into microbial functions and interactions at distinct sites along the buffalo digestive tract.

RESUMO

Objective: Depression is one of the most common problems faced by older adults. Reminiscence therapy, defined as using the recall of past events, feelings, and thoughts facilitating pleasure, is one type of psychotherapy that could alleviate depressive feelings among older adults, improve their quality of life, and help them live independently. Reminiscence therapy originated from geriatric psychiatry, and is an effective non-pharmacological intervention that could be structured or unstructured and be conducted individually or in a group. The current systematic review was designed to summarize and review existing evidence on the effect of reminiscence therapy on depression in older adults. Methods: We conducted a systematic review from January 2000 to Mar 2021 using 10 electronic databases in English and Chinese languages, including Medline, Embase, Cinahl, PsychInfo, Cochrane, Web of Science, Google Scholar, Science Direct, CNKI, and WANFANG. We excluded studies that didn't use randomized controlled trials (RCT) from the meta-analysis. The selected studies were scored using the Cochrane Risk of Bias tool. The RevMan 5.0 was used in subgroup analysis depending on how the interventions were classified. Results: We extracted 527 studies based on keyword searches, of which 10 RCTs met inclusion criteria were included in the meta-analysis. The meta-analysis yielded high heterogeneity, and the analyses of significant subgroups showed that reminiscence therapy has a significant effect on relieving depressive symptoms in older adults. Reminiscence therapy benefits older adults with chronic illness and those on antidepressants as well. The effect and cost-effectiveness of group reminiscence therapy were higher than individual reminiscence therapy. And some specific types of group reminiscence therapy have a significant effect on improving depression and secondary outcomes, including life satisfaction. Although the effectiveness of structured and unstructured group reminiscence on depression has no significant differences according to current evidence, the structured therapy is more replicable, generalizable, and user-friendly due to its detailed protocol for new therapists. Furthermore, reminiscence therapy is more effective for older women and older adults with more severe depressive symptoms. Conclusion: Reminiscence therapy significantly increased older adults' remission from depression and quality of life immediately after the intervention. However, the evidence-based protocol and implementation of reminiscence interventions need to be further developed and standardized to facilitate global use. Moreover, it remains unclear on the long-term effect of reminiscence therapy. Based on the limitations of the current study, more rigorous evidence is needed from studies with large sample sizes, RCT design, and longer follow-up periods. Future studies could also explore the effect of different types of reminiscence therapy. Furthermore, qualitative data should be included to better understand older adults' narrative and experiences with reminiscence therapy. Future studies could also investigate the impact of reminiscence therapy on older relatives as a part of outcome measure to explore the efficacious mechanism of reminiscence therapy in alleviating older adults' depressive symptoms.

RESUMO

Background: The social isolation of older people is a growing public health concern. The proportion of older people in society has increased in recent decades, and it is estimated that ~40% of the population will be aged 50 or above within the next few decades. This systematic review aims to summarize and renew knowledge of the effectiveness of existing interventions for alleviating social isolation of older adults. Methods: Relevant electronic databases, including Cochrane Library, CINAHL, SCOPUS, and Web of Science, were searched by a systematic evaluation method. Eligible randomized controlled trial (RCT) studies were published between 1978 and 2021 in English or Chinese. The primary and secondary outcomes were social isolation and loneliness. The quality of the included RCTs was scored by the Cochrane risk-of-bias tool to assess their quality. Two independent reviewers extracted data, using a standardized form. Narrative synthesis and vote-counting methods were used to summarize and interpret study data. Results: Twenty-four RCTs were finally included in this review. There was evidence of substantial heterogeneity in the interventions delivered. The overall quality of included studies indicated a low-to-medium risk of bias. Eighteen of 24 RCTs showed at least one dimension effect on reducing social isolation. The interventions with accurate targeting of clients in social and public places had more obvious effect. The interventions in which older people are active participants also appeared more likely to be effective. In addition, group intervention activities and individual intervention interviews were effective in improving structural social support; mixed intervention, and group intervention on training support significantly improved functional social support. Conclusions: This study suggests that group and mixed intervention targeting of older adults could be helpful for alleviating social isolation problems. The use of modern technology for remote services could also present good results. More well-conducted RCTs of the effectiveness of social interventions for alleviating social isolation are needed to improve the evidence base. Especially as the debating results of remote interventions, further research in this field should be conducted.

RESUMO

Limited literatures report the management of congenital left atrial appendage aneurysm (LAAA) which is extremely rare. Chest X-ray firstly showed an enlarged left cardiac silhouette for a 3-year-old patient with pneumonia. Echocardiography and magnetic resonance imaging confirmed a large cyst attached to the left atrium. Aneurysmectomy was performed through lateral thoracotomy using step-by-step method and under the guidance of transoesophageal echocardiography. We aim to show the safety and efficacy of this approach applied to children associated with congenital LAAA.

RESUMO

Objective: To investigate the efficacy and safety of percutaneous closure of ventricular septal rupture (VSR) after acute myocardial infarction (AMI) and the risk factors of all-cause mortality at 30 days after operation. Methods: This is a retrospective case series study. A total of 69 patients with post-AMI VSR, underwent percutaneous closure of VSR from October 2013 to May 2020 in Department of Cardiology of Henan Provincial People's Hospital and Department of Cardiology of Central China Fuwai Hospital, were included. Patients were divided into survival group (53 cases) and non-survival group (16 cases) according to the status at 30 days after operation. Clinical data were collected and analyzed during hospitalization. Telephone follow-up was performed 30 days after operation. The primary safety endpoint was occlusion failure and all-cause mortality at 30 days post operation. The secondary safety endpoint was the operation related or non-operation related complications. Efficacy endpoint included NYHA classification of cardiac function, index measured by right heart catheterization and echocardiography. Multivariate logistic regression was performed to analyze the risk factors of all-cause mortality at 30 days after operation. Results: A total of 69 patients, aged 67 (64, 71) years, including 42 women (60.9%), were enrolled in this study. All-cause death occurred in 16 patients (23.2%), including 13 in-hospital death and 3 death during follow-up. There were 4 cases of closure failure (5.8%). Among the 65 patients with successful closure, 12 (18.5%) experienced operation-related complications, among which 8 (12.3%) experienced valve injury. The mortality was significantly higher in patients with operation-related complications than that in patients without operation-related complications (41.7% (5/12) vs. 13.2% (7/53), P = 0.022). One case received percutaneous closure of VSR and PCI, this patient experienced new-onset AMI immediately post procedure and died thereafter (1.5%). One case (1.5%) developed multiple organ failure and 2 cases (3.1%) developed gastrointestinal bleeding post operation. All of the 65 patients with successful occlusion completed postoperative echocardiography, 56 patients completed cardiac function assessment at discharge, and 53 patients who survived up to 30 days post discharge completed clinical follow up by telephone. The NYHA cardiac function at discharge and 30 days after operation were significantly improved as compared to that before operation (P<0.001), the ratio of NYHA Ⅰ and Ⅱ patients was significantly higher post operation at these two time points as compared to baseline level (76.8% (43/56) vs. 23.1% (15/65), P<0.001, 77.4% (41/53) vs. 23.1% (15/65), P<0.001). The pulmonary circulation/systemic circulation blood flow ratio (Qp/Qs), pulmonary artery systolic pressure (PASP) and left ventricular end-diastolic diameter (LVDd) were decreased, aortic systolic pressure (ASP) and left ventricular ejection fraction (LVEF) were increased post operation (P<0.05). Multivariate logistic regression analysis showed that WBC>9.8×109/L (OR=20.94, 95%CI 1.21-362.93, P=0.037) and NT-ProBNP>6 000 ng/L (OR=869.11, 95%CI 2.93-258 058.34, P=0.020) were the independent risk factors of mortality at 30 days. Conclusions: Percutaneous closure in VSR after AMI is safe and effective. The increase of WBC and NT-ProBNP are the independent risk factors of all-cause mortality at 30 days after operation.

RESUMO

Coccidiosis is a major hazard to the chicken industry, but the host's immune response to coccidiosis remains unclear. Here, we performed Eimeria coccidia challenge in 28-day-old ROSS 308 broilers and selected the bursa from the three most severely affected individuals and three healthy individuals for RNA sequencing. We obtained 347 DEGs from RNA-seq and found that 7 upregulated DEGs were enriched in Cytokine-cytokine receptor interaction pathway. As the DEGs with the highest expression abundance in these 7 genes, TNFRSF6B was speculated to participate in the process of host's immune response to coccidiosis. It is showed that TNFRSF6B can polarize macrophages to M1 subtype and promote inflammatory cytokines expression. In addition, the expression of TNFRSF6B suppressed HD11 cells apoptosis by downregulating Fas signal pathway. Besides, TNFRSF6B-mediated macrophages immunity activation can be reversed by apoptosis. Overall, our study indicates that TNFRSF6B upregulated in BAE, is capable of aggravating the inflammatory response by inhibiting macrophages apoptosis via downregulating Fas signal pathway, which may participate in host's immune response to coccidiosis.

RESUMO

BACKGROUND: Idiopathic hyper eosinophilic syndrome (HES) is a rare disease characterized by a sustained increase in eosinophilia. Heart involvement is called Loffler endocarditis. Loffler endocarditis is a serious complication of hyper eosinophilia syndrome, which is characterized by a special type of fibrotic endocarditis. Loffler endocarditis is an inflammatory cardiac condition characterized by eosinophilic infiltration in the heart. The overall prognosis for patients with Loffler endocarditis is very poor. METHODS: In this article we report an 8-year-old girl who was diagnosed as having Loffler endocarditis in thrombotic phase and was successfully treated with surgery. RESULTS: Our patient had a good prognosis during the half-year follow-up. She had no symptoms of heart failure and echocardiography findings were normal. CONCLUSION: The cardiac damage occurred in a three-stage process: the necrotic, thrombotic, and fibrotic stages. This unusual but sometimes life-threatening disease is often detected in the late phase, resulting in no curative strategy available to reverse the disease process. The overall prognosis of patients with Loffler endocarditis is very poor. Current treatments include anticoagulation and anti-eosinophils therapy, and surgery only in selected cases. Surgical treatment of HES in adolescents is very rare. The present case illustrates that with well-controlled peripheral eosinophilia, proper surgical treatment in selected patients can improve their prognosis in the near future but long-term follow-up is necessary.

RESUMO

With the advent of artificial intelligence (AI) in biostatistical analysis and modeling, machine learning can potentially be applied into developing diagnostic models for interstitial cystitis (IC). In the current clinical setting, urologists are dependent on cystoscopy and questionnaire-based decisions to diagnose IC. This is a result of a lack of objective diagnostic molecular biomarkers. The purpose of this study was to develop a machine learning-based method for diagnosing IC and assess its performance using metabolomics profiles obtained from a prior study. To develop the machine learning algorithm, two classification methods, support vector machine (SVM) and logistic regression (LR), set at various parameters, were applied to 43 IC patients and 16 healthy controls. There were 3 measures used in this study, accuracy, precision (positive predictive value), and recall (sensitivity). Individual precision and recall (PR) curves were drafted. Since the sample size was relatively small, complicated deep learning could not be done. We achieved a 76%-86% accuracy with leave-one-out cross validation depending on the method and parameters set. The highest accuracy achieved was 86.4% using SVM with a polynomial kernel degree set to 5, but a larger area under the curve (AUC) from the PR curve was achieved using LR with a l 1-norm regularizer. The AUC was greater than 0.9 in its ability to discriminate IC patients from controls, suggesting that the algorithm works well in identifying IC, even when there is a class distribution imbalance between the IC and control samples. This finding provides further insight into utilizing previously identified urinary metabolic biomarkers in developing machine learning algorithms that can be applied in the clinical setting.

RESUMO

BACKGROUND: Functional disability is the most common disorder that occurs after stroke and seriously affects the quality of life of stroke survivors. Tai Chi Yunshou (TCY), a fundamental form of Tai Chi, is a simple, convenient, and economical exercise therapy from ancient China. Some clinical trials have reported that it improves upper limb function and balance during stroke rehabilitation. Thus, we plan to conduct a systematic review to investigate the effects of TCY in stroke survivors. METHODS: This review will follow the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. We will search English and Chinese databases for randomized controlled trials on TCY for stroke survivors from the dates when the databases were established to 1 July 2020. The English databases will include MEDLINE (PubMed), EMBASE (embase.com), and the Cochrane Central Register of Controlled Trials (Cochrane Library). In addition, the Chinese databases will include the Chinese National Knowledge Infrastructure, the Chinese Biomedical Literature Database, the Chinese Science and Technology Periodical Database, the Wanfang database, and the Chinese Dissertation Database. The primary outcomes will include upper limb function and balance function, as measured by the Fugl-Meyer assessment and Berg balance scale, respectively. Two reviewers will independently screen the studies on the basis of the inclusion criteria and extract data. Review Manager (v5.3) will be used for data synthesis, and Cochrane Collaboration's tool will be used to assess the risk of bias. A fixed effects model or a random effects model will be selected based on the level of heterogeneity. The grading of recommendations assessment, development, and evaluation system will be used to evaluate the quality of the outcomes. RESULTS: This systematic review results will be carried out after the completion of the protocol. CONCLUSIONS: This protocol aims to guide a systematic review and meta-analysis investigating the effects of JCY on upper limb function and body balance in stroke survivors, which will provide evidence for post-stroke rehabilitation training.
