The clinical data of 142 patients with chronic pancreatitis were retrospectively studied. All patients were of Chinese nationality and hospitalized from January 2008 to December 2011. Their ages ranged from 14 to 76 years, with a mean of 43 years. Of 142 patients, there were 72 cases of obstructive chronic pancreatitis(50.70%), 19 cases of alcoholic chronic pancreatitis(13.38%), 14 cases of autoimmune pancreatitis(9.86%) and 37 cases of undetermined etiology(26.06%). Pathologically, the average inflammatory mass diameter was 3.8±3.3 cm, biliary obstruction occurred in 36 cases, gall stones in 70 cases, calcification in 88 cases, ductal dilatation in 61 cases, side branch dilatation in 32 cases, ductal irregularity in 10 cases, lymphocytic inflammation in 23 cases, obliterative phlebitis in 14 cases, extra pancreatic lesion in 19 cases and fibrosis in 142 cases. Location of pancreatic lesion in the region of head(n=97), neck(n=16), body(n=12), tail(n=15) and whole pancreas(n=2) influenced the choice of surgical procedures. Ninety-four patients(66.20%) received surgical treatment and 33.80% received other treatments. After operation, 80.85% of 94 patients experienced decreased pain, and 8.51% of 94 showed recovery of endocrine function but with a complication rate of 12.77%. All the operations were performed successfully. According to the pain scale of European Organization for Research and Treatment of Cancer(QLQ-C30) a decrease from 76±22 to 14±18 was observed. Etiology, pathological characteristics, management and prognosis of chronic pancreatitis in the Chinese population vary from others.展开更多

HPVG has been reported with increasing frequency in medical literature and usually accompanies severe or lethal conditions. The diagnosis of HPVG is usually made by plain abdominal radiography, sonography, color Doppler flow imaging or computed tomography (CT) scan. Currently, the increased use of CT scan and ultrasound in the inpatient setting allows early and highly sensitive detection of such severe illnesses and also the recognition of an increasing number of benign and non-life threatening causes of HPVG. HPVG is not by itself a surgical indication and the treatment depends mainly on the underlying disease. The prognosis is related to the pathology itself and is not influenced by the presence of HPVG. Based on a review of the literature, we discuss in this paper the pathophysiology, risk factors, radiographic findings, management, and prognosis of pathologies associated with HPVG.展开更多

The aim of this study is to determine the incidence and epidemiological characteristics of patients with retroplacental haematoma (RPH) and describe the maternal-foetal complications at Bouaké University Hospital. Methods: This was a cross-sectional prospective, descriptive and analytical study carried out at Bouaké University Hospital over a period of 3 years, from January 1, 2019 to December 31, 2021. All parturients with RPH whose delivery took place at the hospital were included in the study. Data were entered and analysed using EPI INFO software version 7.2.2.6. Results: We recorded 2,0959 deliveries, including 202 cases of RPH, representing an incidence of 0.96%. The 21 to 35 age group accounted for 64.4%, multigestas and large multigestas accounted for 58.5% and multiparas accounted for 41.6%. The main signs on clinical examination were metrorrhagia (100%), arterial hypertension (84.6%) and cervical cerclage (79.7%). Preeclampsia accounted for 50% of per-gestational pathologies. Maternal mortality was 12.9%. Morbidity was dominated by anaemia in 64.1%, followed by disseminated intravascular coagulation (DIC) in 21.8%, and the factors associated with this maternal prognosis were multiple gestations, multiparity, Sher grade IIIb and the occurrence of complications such as DIC, shock, renal complications and HELLP syndrome. Neonatal mortality was 79.2%, and the factors associated with these fetal prognoses were cup size ≥ 5 cm and hematoma weight ≥ 500 g. Conclusion: Better screening of at-risk populations, early diagnosis and treatment in an organised and equipped medical and surgical facility would improve prognosis.展开更多

Hypertensive disorders of pregnancy are among the leading causes of severe maternal morbidity and mortality, particularly in developing countries, maternal hypocalcaemia being a factor favouring the onset of arterial hypertension during pregnancy. The aim was to determine the maternal and perinatal prognosis of patients with hypertensive disorders of pregnancy as a function of serum ionised calcium levels. Material and Methods: A cross-sectional analytical study of 114 patients with arterial hypertension during pregnancy or during pregnancy or in the postpartum period at the HGR/Panzi from 1 January 2021 to 30 June 2022, text was entered using Microsoft Office Word 2010 and the tables were analysed using Excel 2010. The data was analysed using SPSS version 20.0 and Stata 14.0. The associations of the variables were calculated using Pearson's chi-square test, with a significance threshold set at a value of p < 0.05. Study of risk factors, Odds ratios and their confidence intervals were estimated in a univariate analysis. The most determining factors were identified by multivariate analysis using the Forward conditional logistic regression model. Results: The mean gestational age was 34.43 ± 4.327 amenorheas weeks, 46.6% of patients had a vaginal delivery, 66.65% of which were indicated for maternal prognosis, maternal complications were associated with maternal hypocalcaemia in 81, 82% (P = 0.043) and an OR = 3.255 (P = 0.0158) threefold risk that the patient presenting with a complication is likely to be in a state of hypocalcaemia at 95% confidence index, and fetal prognosis was not significantly related to maternal calcaemia. Conclusion: Maternal hypocalcaemia is one of the factors that can influence maternal-foetal complications maternal-fetal complications, early management and prevention of this pathology is pathology is important to reduce maternal-fetal morbidity and mortality.展开更多

They can impact either one or both lungs, which leads to a severe impairment of a person’s ability to breathe normally. Some notable examples of such diseases encompass pneumonia, lung cancer, coronavirus disease 2019 (COVID-19), tuberculosis, and chronic obstructive pulmonary disease (COPD). Consequently, early and precise detection of these diseases is paramount during the diagnostic process. Traditionally, the primary methods employed for the detection involve the use of X-ray imaging or computed tomography (CT) scans. Nevertheless, due to the scarcity of proficient radiologists and the inherent similarities between these diseases, the accuracy of detection can be compromised, leading to imprecise or erroneous results. To address this challenge, scientists have turned to computer-based solutions, aiming for swift and accurate diagnoses. The primary objective of this study is to develop two machine learning models, utilizing single-task and multi-task learning frameworks, to enhance classification accuracy. Within the multi-task learning architecture, two principal approaches exist soft parameter sharing and hard parameter sharing. Consequently, this research adopts a multi-task deep learning approach that leverages CNNs to achieve improved classification performance for the specified tasks. These tasks, focusing on pneumonia and COVID-19, are processed and learned simultaneously within a multi-task model.

文摘Odontogenic keratocyst(OKC)is a common jaw cyst with a high recurrence rate.OKC combined with basal cell carcinoma as well as skeletal and other developmental abnormalities is thought to be associated with Gorlin syndrome.Moreover,OKC needs to be differentiated from orthokeratinized odontogenic cyst and other jaw cysts.Because of the different prognosis,differential diagnosis of several cysts can contribute to clinical management.We collected 519 cases,comprising a total of 2157 hematoxylin and eosinstained images,to develop digital pathology-based artificial intelligence(AI)models for the diagnosis and prognosis of OKC.The Inception_v3 neural network was utilized to train and test models developed from patch-level images.Finally,whole slide imagelevel AI models were developed by integrating deep learning-generated pathology features with several machine learning algorithms.The AI models showed great performance in the diagnosis(AUC=0.935,95%CI:0.898–0.973)and prognosis(AUC=0.840,95%CI:0.751–0.930)of OKC.The advantages of multiple slides model for integrating of histopathological information are demonstrated through a comparison with the single slide model.Furthermore,the study investigates the correlation between AI features generated by deep learning and pathological findings,highlighting the interpretative potential of AI models in the pathology.Here,we have developed the robust diagnostic and prognostic models for OKC.The AI model that is based on digital pathology shows promise potential for applications in odontogenic diseases of the jaw.
文摘The purpose of this study was to investigate the etiology, pathological characteristics, management and prognosis of chronic pancreatitis in the Chinese population. The clinical data of 142 patients with chronic pancreatitis were retrospectively studied. All patients were of Chinese nationality and hospitalized from January 2008 to December 2011. Their ages ranged from 14 to 76 years, with a mean of 43 years. Of 142 patients, there were 72 cases of obstructive chronic pancreatitis(50.70%), 19 cases of alcoholic chronic pancreatitis(13.38%), 14 cases of autoimmune pancreatitis(9.86%) and 37 cases of undetermined etiology(26.06%). Pathologically, the average inflammatory mass diameter was 3.8±3.3 cm, biliary obstruction occurred in 36 cases, gall stones in 70 cases, calcification in 88 cases, ductal dilatation in 61 cases, side branch dilatation in 32 cases, ductal irregularity in 10 cases, lymphocytic inflammation in 23 cases, obliterative phlebitis in 14 cases, extra pancreatic lesion in 19 cases and fibrosis in 142 cases. Location of pancreatic lesion in the region of head(n=97), neck(n=16), body(n=12), tail(n=15) and whole pancreas(n=2) influenced the choice of surgical procedures. Ninety-four patients(66.20%) received surgical treatment and 33.80% received other treatments. After operation, 80.85% of 94 patients experienced decreased pain, and 8.51% of 94 showed recovery of endocrine function but with a complication rate of 12.77%. All the operations were performed successfully. According to the pain scale of European Organization for Research and Treatment of Cancer(QLQ-C30) a decrease from 76±22 to 14±18 was observed. Etiology, pathological characteristics, management and prognosis of chronic pancreatitis in the Chinese population vary from others.
文摘Hepatic portal venous gas (HPVG), an ominous radiologic sign, is associated in some cases with a severe underlying abdominal disease requiring urgent operative intervention. HPVG has been reported with increasing frequency in medical literature and usually accompanies severe or lethal conditions. The diagnosis of HPVG is usually made by plain abdominal radiography, sonography, color Doppler flow imaging or computed tomography (CT) scan. Currently, the increased use of CT scan and ultrasound in the inpatient setting allows early and highly sensitive detection of such severe illnesses and also the recognition of an increasing number of benign and non-life threatening causes of HPVG. HPVG is not by itself a surgical indication and the treatment depends mainly on the underlying disease. The prognosis is related to the pathology itself and is not influenced by the presence of HPVG. Based on a review of the literature, we discuss in this paper the pathophysiology, risk factors, radiographic findings, management, and prognosis of pathologies associated with HPVG.

文摘BACKGROUND Autoimmune enteropathy(AIE)is a rare disease whose diagnosis and long-term prognosis remain challenging,especially for adult AIE patients.AIM To improve overall understanding of this disease’s diagnosis and prognosis.METHODS We retrospectively analyzed the clinical,endoscopic and histopathological characteristics and prognoses of 16 adult AIE patients in our tertiary medical center between 2011 and 2023,whose diagnosis was based on the 2007 diagnostic criteria.RESULTS Diarrhea in AIE patients was characterized by secretory diarrhea.The common endoscopic manifestations were edema,villous blunting and mucosal hyperemia in the duodenum and ileum.Villous blunting(100%),deep crypt lymphocytic infiltration(67%),apoptotic bodies(50%),and mild intraepithelial lymphocytosis(69%)were observed in the duodenal biopsies.Moreover,there were other remarkable abnormalities,including reduced or absent goblet cells(duodenum 94%,ileum 62%),reduced or absent Paneth cells(duodenum 94%,ileum 69%)and neutrophil infiltration(duodenum 100%,ileum 69%).Our patients also fulfilled the 2018 diagnostic criteria but did not match the 2022 diagnostic criteria due to undetectable anti-enterocyte antibodies.All patients received glucocorticoid therapy as the initial medication,of which 14/16 patients achieved a clinical response in 5(IQR:3-20)days.Immunosuppressants were administered to 9 patients with indications of steroid dependence(6/9),steroid refractory status(2/9),or intensified maintenance medication(1/9).During the median of 20.5 months of followup,2 patients died from multiple organ failure,and 1 was diagnosed with non-Hodgkin’s lymphoma.The cumulative relapse-free survival rates were 62.5%,55.6%and 37.0%at 6 months,12 months and 48 months,respectively.CONCLUSION Certain histopathological findings,including a decrease or disappearance of goblet and Paneth cells in intestinal biopsies,might be potential diagnostic criteria for adult AIE.The long-term prognosis is still unsatisfactory despite corticosteroid and immunosuppressant medications,which highlights the need for early diagnosis and novel medications.
文摘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.
文摘This perspective focuses on the recent literature regarding the role of the gut-brain axis(GBA) in fecal microbiota transplantation(FMT) and stem cell therapy(SCT) in Parkinson's disease(PD).PD is the second most common neurodegenerative disease in the United States,yet therapies remain limited.Current research suggests that the GBA may play a role in the pathogenesis of PD.GBAbased FMT as well as SCT offer promising new avenues for PD treatment.Pro bing the interactions between FMT and SCT with the GBA may reveal novel therapeutics for PD.

文摘Emerging evidence indicates that sleep deprivation(SD)can lead to Alzheimer’s disease(AD)-related pathological changes and cognitive decline.However,the underlying mechanisms remain obscure.In the present study,we identified the existence of a microbiota-gut-brain axis in cognitive deficits resulting from chronic SD and revealed a potential pathway by which gut microbiota affects cognitive functioning in chronic SD.Our findings demonstrated that chronic SD in mice not only led to cognitive decline but also induced gut microbiota dysbiosis,elevated NLRP3 inflammasome expression,GSK-3βactivation,autophagy dysfunction,and tau hyperphosphorylation in the hippocampus.Colonization with the“SD microbiota”replicated the pathological and behavioral abnormalities observed in chronic sleep-deprived mice.Remarkably,both the deletion of NLRP3 in NLRP3-/-mice and specific knockdown of NLRP3 in the hippocampus restored autophagic flux,suppressed tau hyperphosphorylation,and ameliorated cognitive deficits induced by chronic SD,while GSK-3βactivity was not regulated by the NLRP3 inflammasome in chronic SD.Notably,deletion of NLRP3 reversed NLRP3 inflammasome activation,autophagy deficits,and tau hyperphosphorylation induced by GSK-3βactivation in primary hippocampal neurons,suggesting that GSK-3β,as a regulator of NLRP3-mediated autophagy dysfunction,plays a significant role in promoting tau hyperphosphorylation.Thus,gut microbiota dysbiosis was identified as a contributor to chronic SD-induced tau pathology via NLRP3-mediated autophagy dysfunction,ultimately leading to cognitive deficits.Overall,these findings highlight GSK-3βas a regulator of NLRP3-mediated autophagy dysfunction,playing a critical role in promoting tau hyperphosphorylation.
文摘Introduction: Retroplacental haematoma (RPH) is a very serious complication of pregnancy, with life-threatening consequences for both the mother and foetus. The aim of this study is to determine the incidence and epidemiological characteristics of patients with retroplacental haematoma (RPH) and describe the maternal-foetal complications at Bouaké University Hospital. Methods: This was a cross-sectional prospective, descriptive and analytical study carried out at Bouaké University Hospital over a period of 3 years, from January 1, 2019 to December 31, 2021. All parturients with RPH whose delivery took place at the hospital were included in the study. Data were entered and analysed using EPI INFO software version 7.2.2.6. Results: We recorded 2,0959 deliveries, including 202 cases of RPH, representing an incidence of 0.96%. The 21 to 35 age group accounted for 64.4%, multigestas and large multigestas accounted for 58.5% and multiparas accounted for 41.6%. The main signs on clinical examination were metrorrhagia (100%), arterial hypertension (84.6%) and cervical cerclage (79.7%). Preeclampsia accounted for 50% of per-gestational pathologies. Maternal mortality was 12.9%. Morbidity was dominated by anaemia in 64.1%, followed by disseminated intravascular coagulation (DIC) in 21.8%, and the factors associated with this maternal prognosis were multiple gestations, multiparity, Sher grade IIIb and the occurrence of complications such as DIC, shock, renal complications and HELLP syndrome. Neonatal mortality was 79.2%, and the factors associated with these fetal prognoses were cup size ≥ 5 cm and hematoma weight ≥ 500 g. Conclusion: Better screening of at-risk populations, early diagnosis and treatment in an organised and equipped medical and surgical facility would improve prognosis.

文摘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.
文摘BACKGROUND Gastric cancer(GC)is one of the most common malignant tumors in the world,and its prognosis is closely related to many factors.In recent years,the incidence of vascular thrombosis in patients with GC has gradually attracted increasing attention,and studies have shown that it may have a significant impact on the survival rate and prognosis of patients.However,the specific mechanism underlying the association between vascular thrombosis and the prognosis of patients with GC remains unclear.AIM To analyze the relationships between vascular cancer support and other clinicopathological factors and their influence on the prognosis of patients with GC.METHODS This study retrospectively analyzed the clinicopathological data of 621 patients with GC and divided them into a positive group and a negative group according to the presence or absence of a vascular thrombus.The difference in the 5-year cumulative survival rate between the two groups was compared,and the relationships between vascular cancer thrombus and other clinicopathological factors and their influence on the prognosis of patients with GC were analyzed.RESULTS Among 621 patients with GC,the incidence of vascular thrombi was 31.7%(197 patients).Binary logistic regression analysis revealed that the degree of tumor differentiation,depth of invasion,and extent of lymph node metastasis were independent influencing factors for the occurrence of vascular thrombi in GC patients(P<0.01).The trend of the χ^(2) test showed that the degree of differentiation,depth of invasion,and extent of lymph node metastasis were linearly correlated with the percentage of vascular thrombi in GC patients(P<0.01),and the correlation between lymph node metastasis and vascular thrombi was more significant(r=0.387).Univariate analysis revealed that the 5-year cumulative survival rate of the positive group was significantly lower than that of the negative group(46.7%vs 73.3%,P<0.01).Multivariate analysis revealed that age,tumor diameter,TNM stage,and vascular thrombus were independent risk factors for the prognosis of GC patients(all P<0.05).Further stratified analysis revealed that the 5-year cumulative survival rate of stage Ⅲ GC patients in the thrombolase-positive group was significantly lower than that in the thrombolase-negative group(36.1%vs 51.4%;P<0.05).CONCLUSION Vascular cancer status is an independent risk factor affecting the prognosis of patients with GC.The combination of vascular cancer suppositories and TNM staging can better judge the prognosis of patients with GC and guide more reasonable treatment.
文摘Hypertensive disorders of pregnancy are among the leading causes of severe maternal morbidity and mortality, particularly in developing countries.

文摘BACKGROUND Advanced gastric cancer is a common malignancy that is often diagnosed at an advanced stage and is still at risk of recurrence after radical surgical treatment.Chemoradiotherapy,as one of the important treatment methods for gastric cancer,is of great significance for improving the survival rate of patients.However,the tumor recurrence and survival prognosis of gastric cancer patients after radio-therapy and chemotherapy are still uncertain.AIM To analyze the tumor recurrence after radical radiotherapy and chemotherapy for advanced gastric cancer and provide more in-depth guidance for clinicians.METHODS A retrospective analysis was performed on 171 patients with gastric cancer who received postoperative adjuvant radiotherapy and chemotherapy in our hospital from 2021 to 2023.The Kaplan-Meier method was used to calculate the recurrence rate and survival rate;the log-rank method was used to analyze the single-factor prognosis;and the Cox model was used to analyze the prognosis associated with multiple factors.RESULTS The median follow-up time of the whole group was 63 months,and the follow-up rate was 93.6%.Stage II and III patients accounted for 31.0%and 66.7%,respec-tively.The incidences of Grade 3 and above acute gastrointestinal reactions and hematological adverse reactions were 8.8%and 9.9%,respectively.A total of 166 patients completed the entire chemoradiotherapy regimen,during which no adverse reaction-related deaths occurred.In terms of the recurrence pattern,17 patients had local recurrence,29 patients had distant metastasis,and 12 patients had peritoneal implantation metastasis.The 1-year,3-year,and 5-year overall survival(OS)rates were 83.7%,66.3%,and 60.0%,respectively.The 1-year,3-year,and 5-year disease-free survival rates were 75.5%,62.7%,and 56.5%,respectively.Multivariate analysis revealed that T stage,peripheral nerve invasion,and the lymph node metastasis rate(LNR)were independent prognostic factors for OS.CONCLUSION Postoperative intensity-modulated radiotherapy combined with chemotherapy for gastric cancer treatment is well tolerated and has acceptable adverse effects,which is beneficial for local tumor control and can improve the long-term survival of patients.The LNR was an independent prognostic factor for OS.For patients with a high risk of local recurrence,postoperative adjuvant chemoradiation should be considered.
文摘Thoracic diseases pose significant risks to an individual's chest health and are among the most perilous medical diseases. They can impact either one or both lungs, which leads to a severe impairment of a person’s ability to breathe normally. Some notable examples of such diseases encompass pneumonia, lung cancer, coronavirus disease 2019 (COVID-19), tuberculosis, and chronic obstructive pulmonary disease (COPD). Consequently, early and precise detection of these diseases is paramount during the diagnostic process. Traditionally, the primary methods employed for the detection involve the use of X-ray imaging or computed tomography (CT) scans. Nevertheless, due to the scarcity of proficient radiologists and the inherent similarities between these diseases, the accuracy of detection can be compromised, leading to imprecise or erroneous results. To address this challenge, scientists have turned to computer-based solutions, aiming for swift and accurate diagnoses. The primary objective of this study is to develop two machine learning models, utilizing single-task and multi-task learning frameworks, to enhance classification accuracy. Within the multi-task learning architecture, two principal approaches exist soft parameter sharing and hard parameter sharing. Consequently, this research adopts a multi-task deep learning approach that leverages CNNs to achieve improved classification performance for the specified tasks. These tasks, focusing on pneumonia and COVID-19, are processed and learned simultaneously within a multi-task model. To assess the effectiveness of the trained model, it is rigorously validated using three different real-world datasets for training and testing.
文摘Bai et al investigate the predictive value of T lymphocyte proportion in Alzheimer's disease(AD)prognosis.Through a retrospective study involving 62 AD patients,they found that a decrease in T lymphocyte proportion correlated with a poorer prognosis,as indicated by higher modified Rankin scale scores.While the study highlights the potential of T lymphocyte proportion as a prognostic marker,it suggests the need for larger,multicenter studies to enhance generalizability and validity.Additionally,future research could use cognitive exams when evaluating prognosis and delve into immune mechanisms underlying AD progression.Despite limitations inherent in retrospective designs,Bai et al's work contributes to understanding the immune system's role in AD prognosis,paving the way for further exploration in this under-researched area.

文摘BACKGROUND Eosinophilic gastroenteritis(EGE)is a chronic recurrent disease with abnormal eosinophilic infiltration in the gastrointestinal tract.Glucocorticoids remain the most common treatment method.However,disease relapse and glucocorticoid dependence remain notable problems.To date,few studies have illuminated the prognosis of EGE and risk factors for disease relapse.AIM To describe the clinical characteristics of EGE and possible predictive factors for disease relapse based on long-term follow-up.METHODS This was a retrospective cohort study of 55 patients diagnosed with EGE admitted to one medical center between 2013 and 2022.Clinical records were collected and analyzed.Kaplan-Meier curves and log-rank tests were conducted to reveal the risk factors for long-term relapse-free survival(RFS).RESULTS EGE showed a median onset age of 38 years and a slight female predominance(56.4%).The main clinical symptoms were abdominal pain(89.1%),diarrhea(61.8%),nausea(52.7%),distension(49.1%)and vomiting(47.3%).Forty-three(78.2%)patients received glucocorticoid treatment,and compared with patients without glucocorticoid treatments,they were more likely to have elevated serum immunoglobin E(IgE)(86.8%vs 50.0%,P=0.022)and descending duodenal involvement(62.8%vs 27.3%,P=0.046)at diagnosis.With a median follow-up of 67 mo,all patients survived,and 56.4%had at least one relapse.Six variables at baseline might have been associated with the overall RFS rate,including age at diagnosis<40 years[hazard ratio(HR)2.0408,95%confidence interval(CI):1.0082–4.1312,P=0.044],body mass index(BMI)>24 kg/m^(2)(HR 0.3922,95%CI:0.1916-0.8027,P=0.014),disease duration from symptom onset to diagnosis>3.5 mo(HR 2.4725,95%CI:1.220-5.0110,P=0.011),vomiting(HR 3.1259,95%CI:1.5246-6.4093,P=0.001),total serum IgE>300 KU/L at diagnosis(HR 0.2773,95%CI:0.1204-0.6384,P=0.022)and glucocorticoid treatment(HR 6.1434,95%CI:2.8446-13.2676,P=0.003).CONCLUSION In patients with EGE,younger onset age,longer disease course,vomiting and glucocorticoid treatment were risk factors for disease relapse,whereas higher BMI and total IgE level at baseline were protective.
