Diagnosis of poorly differentiated adenocarcinoma of the stomach by confocal laser endomicroscopy:A case report

BACKGROUND In recent years,confocal laser endomicroscopy(CLE)has become a new endoscopic imaging technology at the microscopic level,which is extensively performed for real-time in vivo histological examination.CLE can be performed to distinguish benign from malignant lesions.In this study,we diagnosed using CLE an asymptomatic patient with poorly differentiated gastric adenocarcinoma.CASE SUMMARY A 63-year-old woman was diagnosed with gastric mucosal lesions,which may be gastric cancer,in the small curvature of the stomach by gastroscopy.She consented to undergo CLE for morphological observation of the gastric mucosa.Through the combination of CLE diagnosis and postoperative pathology,the intraoperative CLE diagnosis was considered to be reliable.According to our experience,CLE can be performed as the first choice for the diagnosis of gastric cancer.CONCLUSION CLE has several advantages over pathological diagnosis.We believe that CLE has great potential in the diagnosis of benign and malignant gastric lesions.

Associated Factors to Poor Blood Pressure Control in Hypertensives Followed Up at the Campus University Hospital of Lome (Togo)

Introduction: Hypertension is a real public health issue and its control is very difficult. We aim to determine the frequency of uncontrolled hypertension in hypertensive patients followed up as an outpatient at the campus university hospital of Lome (Togo) and to search for the associated factors. Methodology: The study was cross-sectional, descriptive and analytical, carried out from February (2022) to August 2022 in 260 hypertensive patients aged 22 years old, followed up (on an) as an outpatient for at least 3 months at the Lome University Hospital campus. A univariate then multivariate analysis were conducted in order to highlight the most common factors significantly linked to uncontrolled. Results: The mean age of hypertensives was 56.4 ± 12.7 years, the sex ratio (M/F) was 0.59. Prevalence of uncontrolled blood pressure was 42%. Associated Factors to poor blood pressure control in our study were age > 60 years (OR = 1.6 CI [1.17 - 2.50]), low socio-economic level (OR = 2.2 CI [1.96 - 4.33]), high cardiovascular risk level (OR = 3.1 CI [2.18 - 4.52]), non-adherence to regular blood pressure monitoring (OR = 3.3 CI [2.21 - 5.55]), low compliance to treatment (OR = 4.1 CI [2.33 - 6.76]) and a chronic renal failure (OR = 2.1 CI [1.21 - 3.10]). Conclusion: Nearly half of the hypertensives in our study had poorly controlled blood pressure by antihypertensive treatment medication. The factors of this poor control were age > 60 years, low socio-economic level, high or very high level of cardiovascular risk, low compliance to treatment, and renal failure.

Gallbladder carcinosarcoma with a poor prognosis: A case report

BACKGROUND Carcinosarcoma of the gallbladder is a rare malignant tumor with a very poor prognosis.To date,only approximately 100 patients have been reported in the English literature.The prognosis of this tumor type is poor,the preoperative diagnosis is difficult,and there is a possibility of a misdiagnosis.We present an unsuccessful case of carcinosarcoma of the gallbladder with a preoperative misdiagnosis and rapid early postoperative recurrence.Therefore,we have a deeper understanding of the poor prognosis of gallbladder carcinosarcoma(GBC)patients.CASE SUMMARY The patient is a 65-year-old male.He was admitted to the hospital because of right upper abdomen distending pain and discomfort for half a month.Abdominal magnetic resonance imaging revealed a polycystic mass in the right lobe of the liver and the fossa of the gallbladder.After admission,the patient was diagnosed with a liver abscess,which was treated by abscess puncture drainage.Obviously,this treatment was unsuccessful.Hepatectomy and cholecystectomy were performed one month after the puncture.Postoperative pathologic examination revealed carcinosarcoma of the gallbladder,and the resected specimen contained two tumor components.One month after surgery,the patient's tumor recurred in situ and started to compress the duodenum,resulting in duodenal obstruction and bleeding.The treatment was not effective.The patient died of gastrointestinal hemorrhage and hypovolemic shock.CONCLUSION Carcinosarcoma of the gallbladder is a rare malignant tumor that is easily misdiagnosed preoperatively and has a poor prognosis.

Autosomal Dominant Polycystic Kidney Disease: Epidemiological, Clinical Aspects and Predictive Factors of Poor Renal Prognosis (About 300 Cases)

Introduction: Autosomal dominant polycystic kidney disease (ADPKD) is a common, multisystemic, and progressive hereditary disease. It accounts for 6 to 8% of incident cases of end-stage chronic renal disease (ESRD) in developed countries. The aim of this study is to describe the predictive factors for the development of end-stage chronic kidney disease (CKD) in the course of this disease. Material and Methods: This is a retrospective, descriptive, and analytical study including 300 cases of ADPKD collected at the Nephrology Department of Ibn-Sina Hospital in Rabat over a period of 30 years (1993 to 2023). Included in the study are all patients with ADPKD meeting the ultrasound diagnostic criteria. The analysis focused on demographic, clinical, paraclinical, evolutionary data, as well as prognostic factors associated with renal function deterioration. Results: The mean age of patients at diagnosis is 51.53 +/− 17 years [16 - 93] with a male predominance. The median serum creatinine at diagnosis is 15.5 mg/l [10 - 34]. 21% of patients had ESRD (eGFR 300 mg/24h (21%). The most common cystic complication is hemorrhage (12.3%). 21.3% of patients had hepatorenal polycystic disease. In adjusted analysis, the predictive risk factors for the occurrence of ESRD were smoking (p = 0.019), anemia (p Conclusion: ADPKD can progress insidiously to ESRD. Identification and early treatment of predictive factors for poor renal prognosis could contribute to a better outcome for this disease.

Discussion on the Ideological and Political Education for Poor College Students

At present,ideological and political education is significant for poor college students.The focus of funding for poor students has gradually transformed from providing economic support for them to ideological and spiritual help,which puts forward higher requirements on how to carry out ideological and political work.It also requires us to advance the work of ideological and moral education and put it in the most important position in the ideological and educational work for poor college students.Combined with the reality of poor college students,we will adhere to the idea of being student-oriented and endeavor to enhance the effectiveness,pertinence,and relevance of the work of ideological and political education.This paper analyzes the significance and problems of ideological and political education for poor college students and puts forward effective ways to solve the problems from the levels of ideology,cognition,and teaching staff.

Human mesenchymal stem cells exhibit altered mitochondrial dynamics and poor survival in high glucose microenvironment

BACKGROUND Mesenchymal stem cells(MSCs)are a type of stem cells that possess relevant regenerative abilities and can be used to treat many chronic diseases.Diabetes mellitus(DM)is a frequently diagnosed chronic disease characterized by hyperglycemia which initiates many multisystem complications in the long-run.DM patients can benefit from MSCs transplantation to curb down the pathological consequences associated with hyperglycemia persistence and restore the function of damaged tissues.MSCs therapeutic outcomes are found to last for short period of time and ultimately these regenerative cells are eradicated and died in DM disease model.AIM To investigate the impact of high glucose or hyperglycemia on the cellular and molecular characteristics of MSCs.METHODS Human adipose tissue-derived MSCs(hAD-MSCs)were seeded in low(5.6 mmol/L of glucose)and high glucose(25 mmol/L of glucose)for 7 d.Cytotoxicity,viability,mitochondrial dynamics,and apoptosis were deplored using specific kits.Western blotting was performed to measure the protein expression of phosphatidylinositol 3-kinase(PI3K),TSC1,and mammalian target of rapamycin(mTOR)in these cells.RESULTS hAD-MSCs cultured in high glucose for 7 d demonstrated marked decrease in their viability,as shown by a significant increase in lactate dehydrogenase(P<0.01)and a significant decrease in Trypan blue(P<0.05)in these cells compared to low glucose control.Mitochondrial membrane potential,indicated by tetramethylrhodamine ethyl ester(TMRE)fluorescence intensity,and nicotinamide adenine dinucleotide(NAD+)/NADH ratio were significantly dropped(P<0.05 for TMRE and P<0.01 for NAD+/NADH)in high glucose exposed hAD-MSCs,indicating disturbed mitochondrial function.PI3K protein expression significantly decreased in high glucose culture MSCs(P<0.05 compared to low glucose)and it was coupled with significant upregulation in TSC1(P<0.05)and downregulation in mTOR protein expression(P<0.05).Mitochondrial complexes I,IV,and V were downregulated profoundly in high glucose(P<0.05 compared to low glucose).Apoptosis was induced as a result of mitochondrial impairment and explained the poor survival of MSCs in high glucose.CONCLUSION High glucose impaired the mitochondrial dynamics and regulatory proteins in hAD-MSCs ensuing their poor survival and high apoptosis rate in hyperglycemic microenvironment.

Increased MAD2L2 expression predicts poor clinical outcome in Colon Adenocarcinoma

Background:Colon adenocarcinoma(COAD)is the second leading cause of cancer death worldwide thus,identification of COAD biomarkers is critical.Mitotic Arrest Deficient 2 Like 2(MAD2L2)is a key factor in mammalian DNA damage repair and is highly expressed in many malignant tumors.This is a comprehensive study of MAD2L2 expression,its diagnostic value,prognostic analysis,potential biological function,and impact on the immune system of patients with COAD.Methods:Gene expression,clinical relevance,prognostic analysis,diagnostic value,GO/KEGG cluster analysis,data obtained from TCGA,and bioinformatics statistical analysis were performed using the R package.Immune responses to MAD2L2 expression in COAD were analyzed using TIMER.The expression of MAD2L2 in HCT116 cells induced by the inflammatory factor TNF-αwas detected using Western blot.Results:Our results underscore the clinical diagnostic value and potential biological significance of MAD2L2 in patients with COAD.A high level of MAD2L2 expression has been found in COAD and correlated with tumor status and colon polyps.ROC curve analysis showed that MAD2L2 expression has high diagnostic value in COAD.Analysis of immune infiltration results showed that MAD2L2 expression was positively correlated with neutrophil levels.The western blot results demonstrated that MAD2L2 was dose-dependently present with TNF-α.GO/KEGG revealed that MAD2L2 overexpressed and coexpressed genes were mostly involved in biological functions,including hypoxia response,response to reduced oxygen levels,mitochondrial translation elongation,and other processes.Conclusion:MAD2L2 as a new COAD biomarker contributes to our understanding of how alterations in gene expression and the immunological environment contribute to the development of colon cancer.Following further investigation,MAD2L2 may prove to be a viable target factor for clinical diagnosis and therapy of COAD.

Long term outcomes of Cohen’s cross trigonal reimplantation for primary vesicoureteral reflux in poorly functioning kidney

BACKGROUND Open ureteric reimplantation by cross trigonal technique described by Cohen is considered a common surgical option for correction of vesicoureteral reflux(VUR). There is a lack of evidence in literature though for what happens to such kidneys, in the long run, particularly those which are poorly functioning.AIM To assess the long-term outcomes of ureteric reimplantation in poorly functioning kidneys in children with unilateral primary VUR.METHODS Children with unilateral primary VUR and a relative renal function of less than 35% who underwent open or laparoscopic ureteric reimplantation between January 2005 and January 2017 were included in the study. Patients who had a follow up of less than five years were excluded. Preoperative evaluation consisted of a voiding cystourethrogram and Dimercaptosuccinic acid(DMSA) scan. In the follow-up period, patients underwent a diuretic scan at 6 weeks and 6 months.Follow up ultrasound was done for change in grade of hydronephrosis and retrovesical ureteric diameter. Subsequent follow up was done at 6 monthly intervals with evaluation for proteinuria and hypertension and any recurrent urinary tract infection(UTI). For assessment of cortical function, DMSA was repeated annually for 5 years after surgery. A paired-samples t-test was used to test the mean difference of DMSA between pre-post observations.RESULTS During this period, 36 children underwent ureteric reimplantation for unilateral primary VUR. After excluding those with insufficient follow-up, 31 were included in the analysis. Most of the patients were males(n = 26/31, 83.8%). Patient’s age(mean ± SD, range) was 5.21 ± 3.71, 1-18 years. The grades of VUR were grade Ⅱ(1patient), grade Ⅲ(8 patients), grade Ⅳ(10 patients), and grade Ⅴ(12 patients). The pre and postoperative DMSA was 24.064 ± 12.02 and 24.06 ± 10.93, which was almost the same(statistically equal, paired-samples t-test: P = 0.873). The median(range) follow-up duration was 82(60-120)mo. One patient had persistent reflux after surgery(preoperative: grade Ⅳ, postoperative: grade Ⅲ), and the very same patient developed recurrent UTI. The difference in the preoperative and postoperative DRF was less than 10% in 29 patients. In one patient, the DRF decreased by 17%(22% to 05%) while in another patient, the DRF increased by 12%(25% to 37%) after surgery. None of the patients had an increase in scarring after surgery. 15% of patients were hypertensive before surgery and all of them continued to be hypertensive after surgery while none developed hypertension after surgery. None of the patients had significant proteinuria(> 150 mg/d) during the follow-up period.CONCLUSION Children with unilateral primary VUR and poorly functioning kidney maintain the renal function over the long term in most cases. Hypertension and proteinuria do not progress over time in these patients.

CT心功能参数结合生化指标及Wells评分在急性肺动脉栓塞30 d不良预后中的评估价值

目的 探讨256层螺旋CT心功能相关参数、实验室指标及Wells评分对急性肺栓塞(acute pulmonary embolism, APE)严重程度的诊断效能,观察联合应用对提高急性肺栓塞患者30 d不良预后的预测价值。方法 纳入2018年5月至2021年11月行肺CT血管造影(CTPA)检查确诊为急性肺动脉栓塞住院患者进行回顾性分析,随访30 d且资料齐全者共225例,对照组为同期接受CTPA检查并确诊无肺栓塞患者70例。收集患者临床资料和实验室指标[肌酸激酶(CK)、肌酸激酶-特异性同工酶(CK-MB)和D-二聚体],计算Wells评分。采用心功能软件定量测量右心室(RV)、左心室(LV)体积;分别在横轴位图像、重建四腔心层面上测量右、左心室短径及截面积,计算其比值。对2组患者的上述定量指标进行分析。结果 2组患者肺部感染、冠心病史、既往肺栓塞或深静脉血栓病史、癌症活动期、手术/制动史及心率≥100次/min比较差异有统计学意义(P<0.05)。RVD/LVD-ax、RVA/LVA-ax、RVD/LVD-4ch、RVA/LVA-4ch、RVV/LVV、D-二聚体及Wells评分在对照组、急性肺栓塞预后良好与预后不良间差异有统计学意义(P<0.05)。RVD/LVD-ax在预测30 d不良预后及早期死亡方面AUC值最大,分别为0.692、0.724。RVA/LVA-ax与D-二聚体、Wells评分三者联合检测时在预测早期死亡方面AUC值最大。ROC曲线分析显示冠状窦直径>8.65 mm时急性肺栓塞后右心后负荷增加的风险增大。结论 RVA/LVA-ax与D-二聚体、Wells评分三者联合预测效能最佳;与重建四腔心径线、面积及体积相比,横轴位测量心脏形态改变对评价APE预后更优;当冠状窦直径>8.65 mm时急性肺栓塞后右心后负荷增加的风险增大,可帮助临床进行风险分层。

早期家庭康复干预对单调性扭动运动早产儿神经行为发育的影响

目的 探讨早期家庭康复干预对单调性扭动运动早产儿神经行为发育的影响。方法 选取2022年4月至2023年1月河北省唐山市妇幼保健院儿童康复科全身运动评估结果为单调性扭动运动的64例早产儿为研究对象。按照随机数字表法将其分为干预组和对照组,各32例。对照组给予常规家庭护理干预,干预组实施早期家庭康复干预,持续12周。比较两组干预后不安运动阶段结果;比较两组干预前后各能区发育商。结果 两组不安运动阶段结果比较,差异无统计学意义(P>0.05)。干预后,两组各能区发育商均高于干预前,且干预组大运动、个人-社交行为发育商高于对照组(P<0.05)。结论 对单调性扭动运动早产儿应用早期家庭康复干预可以有效改善大运动、个人-社交行为,值得临床推广应用。
