Specifically, nutritional interventions may have an impact on the hypothalamic-pituitary axis resulting in positive health outcomes. A retrospective health status survey of 386 respondents was conducted to investigate the potential of a dietary supplement, Nutrifii<sup>TM</sup> Renew, for improving various health outcomes in comparison to a multivitamin/mineral control group. Among those who ingested Renew, 95% reported experiencing at least some improvement in one or more health categories. Compared to the multivitamin/mineral group, the Renew group reported earlier and/or greater improvements in several health status categories including sleep, reproductive health, memory, energy/stamina, skin and hair quality, flexibility, exercise recovery and feeling rested in the morning. A clear majority (84.9%) of Renew consumers reported experiencing noticeable improvement in some aspect of their health within one month. Among those who felt an improvement in sleep, most reported experiencing a change within one week. These improvements were likely due to the synergistic effects of L-arginine, L-citrulline, L-lysine, and botanical extracts on nitric oxide production, growth hormone (GH) release, and sleep quality. The observed improvements in skin elasticity and hair growth may be related to increased GH levels and IGF-1 production. Overall, these findings suggest that Renew may have potential as a dietary intervention for improving various health outcomes beyond those provided by multivitamin/mineral supplementation alone. Further studies are needed to confirm these findings and elucidate the underlying mechanisms of action.展开更多

[Methods] A retrospective analysis was made on the EQA of humoral morphology by Guangxi Clinical Laboratory Center from 2010 to 2022, and the number of participating laboratories, the rate of return, sample types and maps of EQA of humoral morphology such as urine sediment, vaginal secretions and so on(except feces), and the reasons for the high error rate of the results of the participating laboratories were analyzed. [Results] The number of laboratories participating in the assessment of humoral morphology increased from 98 in 2010 to 371 in 2022. Except for 2011(90.98%), the rate of return was more than 94%, and the highest rate of return was up to 100%. A total of 119 pictures of EQA of humoral morphology were studied, including 101 urine sediment smears, 13 vaginal secretions smears and 5 other smears. The types of specimens were relatively comprehensive. The distribution of the maps was basically reasonable. The urinary sediment was mainly composed of crystalline salts, followed by tubes, and cells and fungi ranked third. The coverage was relatively complete. The error rate of return results from high to low were bacteria(error rate was equal to 40%), tubes and crystalline salts(error rate was close to 29%), and cells and fungi(error rate was about 14%). The main cases with high error rate of return results are as follows: the difference between different tubes was not clear, and the diversity of crystal morphology was not understood enough;the phase division of cells in the same system was wrong. [Conclusions] The analysis and summary of the reasons for the high error rate of the data and results of Guangxi's EQA of humoral morphology is helpful for laboratory physicians to improve their awareness of morphological examination and identify clearly the error type and blurred concept, and lays a foundation for Guangxi Clinical Laboratory Center to carry out EQA of humoral morphology more specifically.展开更多

The presence and stage of precancerous lesions as well as subtype of intestinal metaplasia at the baseline endoscopy got evaluated. Literature mini-review was performed.RESULTS Out of 1681 subjects in the Biobank, gastric adenocarcinoma was detected in five cases in whom previous endoscopy data with biopsies either from the corpus or antral part were available. All of the patients had incomplete intestinal metaplasia during the baseline endoscopy;all three subjects in whom intestinal metaplasia subtyping was performed according to Filipe et al, had Type Ⅲ intestinal metaplasia. Two of the five cases had low Operative Link on Gastritis Assessment(OLGA) and Operative Link on Gastritis Intestinal Metaplasia Assessment(OLGIM) stages(Ⅰ-Ⅱ) at the baseline.CONCLUSION The presence of incomplete intestinal metaplasia, in particular, that of Type Ⅲ is a better predictor for gastric adenocarcinoma development than OLGA/OLGIM staging system.

文摘Traumatic spinal cord injury is potentially catastrophic and can lead to permanent disability or even death.China has the largest population of patients with traumatic spinal cord injury.Previous studies of traumatic spinal cord injury in China have mostly been regional in scope;national-level studies have been rare.To the best of our knowledge,no national-level study of treatment status and economic burden has been performed.This retrospective study aimed to examine the epidemiological and clinical features,treatment status,and economic burden of traumatic spinal cord injury in China at the national level.We included 13,465 traumatic spinal cord injury patients who were injured between January 2013 and December 2018 and treated in 30 hospitals in 11 provinces/municipalities representing all geographical divisions of China.Patient epidemiological and clinical features,treatment status,and total and daily costs were recorded.Trends in the percentage of traumatic spinal cord injuries among all hospitalized patients and among patients hospitalized in the orthopedic department and cost of care were assessed by annual percentage change using the Joinpoint Regression Program.The percentage of traumatic spinal cord injuries among all hospitalized patients and among patients hospitalized in the orthopedic department did not significantly change overall(annual percentage change,-0.5%and 2.1%,respectively).A total of 10,053(74.7%)patients underwent surgery.Only 2.8%of patients who underwent surgery did so within 24 hours of injury.A total of 2005(14.9%)patients were treated with high-dose(≥500 mg)methylprednisolone sodium succinate/methylprednisolone(MPSS/MP);615(4.6%)received it within 8 hours.The total cost for acute traumatic spinal cord injury decreased over the study period(-4.7%),while daily cost did not significantly change(1.0%increase).Our findings indicate that public health initiatives should aim at improving hospitals’ability to complete early surgery within 24 hours,which is associated with improved sensorimotor recovery,increasing the awareness rate of clinical guidelines related to high-dose MPSS/MP to reduce the use of the treatment with insufficient evidence.

文摘BACKGROUND For children and adolescents,deliberate self-harm(DSH)is becoming a mental health problem of concern.Despite several studies on the prevalence and factors of DSH in the world,there is little information on DSH among children and adolescents in China.This study explores the prevalence,types,associated risk factors and tendency of DSH in pediatric psychiatric inpatients in China.AIM To understand the situation of DSH among hospitalized children and adolescents and its related factors.METHODS In this study,we retrospectively studied 1414 hospitalized children and adolescents with mental illness at Xiamen Mental Health Center from 2014 to 2019,extracted the demographic and clinical data of all patients,and analyzed clinical risk factors of DSH.RESULTS A total of 239(16.90%)patients engaged in at least one type of DSH in our study.Cutting(n=115,48.12%)was the most common type of DSH.Females(n=171,71.55%)were more likely to engage in DSH than males(n=68,28.45%).DSH was positively associated with depressive disorders[OR=3.845(2.196-6.732);P<0.01],female[OR=2.536(1.815-3.542);P<0.01],parental marital status[OR=5.387(2.254-12.875);P<0.01]and negative family history of psychiatric illness[OR=7.767(2.952-20.433);P<0.01],but not with occupation,substance use and history of physical abuse.CONCLUSION Our findings suggest that for patients with depression,females,an abnormal marriage of parents,and no history of mental illness,attention should be paid to the occurrence of DSH.
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BACKGROUND Patients with diabetes mellitus(DM)are predisposed to an increased risk of infection signifying the importance of vaccination to protect against its potentially severe complications.The Centers for Disease Control and Prevention/Advisory Committee on Immunization Practices(CDC/ACIP)issued immunization recommendations to protect this patient population.AIM To assess the adherence of patients with DM to the CDC/ACIP immunization recommendations in Saudi Arabia and to identify the factors associated with the vaccine adherence rate.METHODS An observational retrospective study conducted in 2023 was used to collect data on the vaccination records from 13 diabetes care centers in Saudi Arabia with 1000 eligible patients in phase I with data collected through chart review and 709 patients in phase II through online survey.RESULTS Among participants,10.01%(n=71)had never received any vaccine,while 85.89%(n=609)received at least one dose of the coronavirus disease 2019(COVID-19)vaccine,and 34.83%(n=247)had received the annual influenza vaccine.Only 2.96%(n=21),2.11%(n=15),and 1.12%(n=8)received herpes zoster,tetanus,diphtheria,and pertussis(Tdap),and human papillomavirus(HPV)vaccines,respectively.For patients with DM in Saudi Arabia,the rate of vaccination for annual influenza and COVID-19 vaccines was higher compared to other vaccinations such as herpes zoster,Tdap,pneumococcal,and HPV.Factors such as vaccine recommendations provided by family physicians or specialists,site of care,income level,DM-related hospitalization history,residency site,hemoglobin A1c(HbA1c)level,and health sector type can significantly influence the vaccination rate in patients with DM.Among non-vaccinated patients with DM,the most reported barriers were lack of knowledge and fear of side effects.This signifies the need for large-scale research in this area to identify additional factors that might facilitate adherence to CDC/ACIP vaccine recommendations in patients with DM.CONCLUSION In Saudi Arabia,patients with DM showed higher vaccination rates for annual influenza and COVID-19 vaccines compared to other vaccinations such as herpes zoster,Tdap,pneumococcal,and HPV.Factors such as vaccine recommendations provided by family physicians or specialists,the site of care,income level,DM-related hospitalization history,residency site,HbA1c level,and health sector type can significantly influence the vaccination rate in patients with DM.

文摘Objective:Accurate measurement of QT interval,the ventricular action potential from depolarization to repolarization,is important for the early detection of Long QT syndrome.The most effective QT correction(QTc)formula has yet to be determined in the pediatric population,although it has intrinsically greater extremes in heart rate(HR)and is more susceptible to errors in measurement.The authors of this study compare six dif-ferent QTc methods(Bazett,Fridericia,Framingham,Hodges,Rautaharju,and a computer algorithm utilizing the Bazett formula)for consistency against variations in HR and RR interval.Methods:Descriptive Retrospective Study.We included participants from a pediatric cardiology practice of a community hospital who had an ECG performed in 2017.All participants were healthy patients with no past medical history and no regular med-ications.Results:ECGs from 95 participants from one month to 21 years of age(mean 9.7 years)were included with a mean HR of 91 beats per minute(bpm).The two-sample paired t-test or Wilcoxon signed-rank test assessed for any difference between QTc methods.A statistically significant difference was observed between every combination of two QTc formulae.The Spearman’s rank correlation analysis explored the QTc/HR and QTc/RR relationships for each formula.Fridericia method was most independent of HR and RR with the lowest absolute value of correlation coefficients.Bazett and Computer had moderate correlations,while Framingham and Rautaharju exhibited strong correlations.Correlations were positive for Bazett and Computer,reflecting results from prior studies demonstrating an over-correction of Bazett at higher HRs.In the linear QTc/HR regression analysis,Bazett had the slope closest to zero,although Computer,Hodges,and Fridericia had comparable values.Alternatively,Fridericia had the linear QTc/RR regression coefficient closest to zero.The Bland-Altman method assessed for bias and the limits of agreement between correction formulae.Bazett and Computer exhibited good agreement with minimal bias along with Framingham and Rautaharju.To account for a possible skewed distri-bution of QT,all the above analyses were also performed excluding the top and bottom 2%of data as sorted by heart rate ranges(N=90).Results from this data set were consistent with those derived from all participants(N=95).Conclusions:Overall,the Fridericia correction method provided the best rate correction in our pedia-tric study cohort.
文摘BACKGROUND Total knee arthroplasty(TKA)can improve pain,quality of life,and functional outcomes.Although uncommon,postoperative complications are extremely consequential and thus must be carefully tracked and communicated to patients to assist their decision-making before surgery.Identification of the risk factors for complications and readmissions after TKA,taking into account common causes,temporal trends,and risk variables that can be changed or left unmodified,will benefit this process.AIM To assess readmission rates,early complications and their causes after TKA at 30 days and 90 days post-surgery.METHODS This was a prospective and retrospective study of 633 patients who underwent TKA at our hospital between January 1,2017,and February 28,2022.Of the 633 patients,28 were not contactable,leaving 609 who met the inclusion criteria.Both inpatient and outpatient hospital records were retrieved,and observations were noted in the data collection forms.RESULTS Following TKA,the 30-day and 90-day readmission rates were determined to be 1.1%(n=7)and 1.8%(n=11),respectively.The unplanned visit rate at 30 days following TKA was 2.6%(n=16)and at 90 days was 4.6%(n=28).At 90 days,the unplanned readmission rate was 1.4%(n=9).Reasons for readmissions included medical(27.2%,n=3)and surgical(72.7%,n=8).Unplanned readmissions and visits within 90 days of follow-up did not substantially differ by age group(P=0.922),body mass index(BMI)(P=0.633),unilateral vs bilateral TKA(P=0.696),or patient comorbidity status(30-day P=0.171 and 90-day P=0.813).Reoperation rates after TKA were 0.66%(n=4)at 30 days and 1.15%(n=8)at 90 days.The average length of stay was 6.53 days.CONCLUSION In this study,there was a low readmission rate following TKA.There was no significant correlation between readmission rate and patient factors such as age,BMI,and co-morbidity status.

文摘BACKGROUND In recent years,approximately half of the newly diagnosed cases and mortalities attributed to hepatocellular carcinoma(HCC)have been reported in China.Despite the high incidence of HCC,there remains a paucity of data regarding the natural growth pattern and the determination of optimal surveillance intervals specific to the Chinese population.AIM To quantify the natural tumor growth pattern of HCC in regional China.METHODS A retrospective analysis was performed on patients from a single institution in Southwest China who had undergone two or more serial dynamic computed tomography or magnetic resonance imaging scans between 2014 and 2020,without having received any anti-cancer therapy.Tumor growth was assessed using tumor volume doubling time(TVDT)and tumor growth rate(TGR),with volumes measured manually by experienced radiologists.Simple univariate linear regression and descriptive analysis were applied to explore associations between growth rates and clinical factors.RESULTS This study identifies the median TVDT for HCC as 163.4 d,interquartile range(IQR)72.1 to 302.3 d,with a daily TGR of 0.42%(IQR 0.206%-0.97%).HCC growth patterns reveal that about one-third of tumors grow indolently with TVDT exceeding 270 d,another one-third of tumors exhibit rapid growth with TVDT under 90 d,and the remaining tumors show intermediate growth rates,with TVDT ranging between 3 to 9 months.CONCLUSION The identified TGRs support biannual surveillance and follow-up for HCC patients in certain regions of China.Given the observed heterogeneity in HCC growth,further investigation is warranted.
文摘Despite being within the intertropical region of the planet,the Mexican territory still has glacier-covered mountains.In recent decades,important advances have been made in studies on glaciology and periglacial environment in Mexico both for current and past conditions.However,in spite of Cofre de Perote volcano(4200 m a.s.l.)being a strategically located mountain,it has not yet been studied in regards to the glacial and periglacial processes;in fact,those dynamics have modified the mountain massifs in the past.To complement the series of studies on glacial history in the high mountain environment of México,this study reconstructs the glacial cover and the periglacial environment of the volcano surface during the final stage of the Late Pleistocene based on climatic retrospective and through the identification of geomorphological features.The findings indicate the existence of a large glacier(ice cap)that covered the northern,western,and southern slopes of the mountain;while in the eastern sector there were two small glaciers,one being of cirque type,and the other of valley type.The current temperature conditions prevent the occurrence of permanent ice bodies;at the same time,it was found that the periglacial blockfields of the slopes is a legacy of the climatic conditions that prevailed at the end of Late Pleistocene.

文摘BACKGROUND Hemorrhoidal disease(HD)is considered a low-severity pathology by both general population and physicians,but the lengthy conservative therapy and postoperative complications suggest otherwise.AIM To assess the effectiveness of different treatment options,both conservative and surgical,in contrast with some preexisting comorbidities.METHODS We conducted a retrospective,10-yearlong study between January 2011 and December 2021 in two surgical centers,a private and a state-owned hospital.We compared the efficacy and safety of several treatment options,such as open hemorrhoidectomy,stapled hemorrhoidopexy,rubber band ligation and infrared coagulation in terms of complication rates and types and their correlation with different preexisting comorbidities such as inflammatory bowel disease(IBD),use of anticoagulant medication(AM)and liver cirrhosis.We also conducted a 20-years long PubMed research(1.263 articles)for relevant comparisons.RESULTS Our study recorded 10940 patients with HD,10241 with conservative and 699 with surgical treatment.Out of these,the male-to-female ratio of 1.3,and a peak in age distribution between 59 and 68 years old(32%of patients).For the entire study,we recorded a 90%incidence of immediate pain,immediate bleeding in 1.5%(11 cases),delayed bleeding in 1.0%(7 cases),and 0.6%surgical site infections.Urinary retention was also present,with 0.2%of patients,anal stricture in 1%and fecal incontinence for 0.5%of patients(4 cases).We recorded no severe complications such as Fournier`s gangrene or rectovaginal perforations.IBD accounted for 6%of the patients,with ulcerative colitis in 12%and Chron`s disease in 10.5%.6.6%of the patients had AM,determining 4%immediate and 2%delayed bleeding,in surgically treated patients.CONCLUSION Our study determined that most common complications(pain,urinary retention,bleeding,and stricture)are correlated with each surgical technique and pre-existing comorbidities.
文摘Dietary factors play an important role in human health. Specifically, nutritional interventions may have an impact on the hypothalamic-pituitary axis resulting in positive health outcomes. A retrospective health status survey of 386 respondents was conducted to investigate the potential of a dietary supplement, Nutrifii<sup>TM</sup> Renew, for improving various health outcomes in comparison to a multivitamin/mineral control group. Among those who ingested Renew, 95% reported experiencing at least some improvement in one or more health categories. Compared to the multivitamin/mineral group, the Renew group reported earlier and/or greater improvements in several health status categories including sleep, reproductive health, memory, energy/stamina, skin and hair quality, flexibility, exercise recovery and feeling rested in the morning. A clear majority (84.9%) of Renew consumers reported experiencing noticeable improvement in some aspect of their health within one month. Among those who felt an improvement in sleep, most reported experiencing a change within one week. These improvements were likely due to the synergistic effects of L-arginine, L-citrulline, L-lysine, and botanical extracts on nitric oxide production, growth hormone (GH) release, and sleep quality. The observed improvements in skin elasticity and hair growth may be related to increased GH levels and IGF-1 production. Overall, these findings suggest that Renew may have potential as a dietary intervention for improving various health outcomes beyond those provided by multivitamin/mineral supplementation alone. Further studies are needed to confirm these findings and elucidate the underlying mechanisms of action.
文摘BACKGROUND Although immune checkpoint inhibitor(ICI)therapy has improved the prognosis of unresectable hepatocellular carcinoma(HCC),it has also resulted in unique immune-related adverse events(irAEs).The relationship between irAE and treatment outcomes in ICI-treated unresectable HCC patients remains unknown.AIM To elucidate the correlation between immune-related toxic effects and prognosis in patients with unresectable HCC treated with pembrolizumab.METHODS From March 2019 to February 2021,a total of 190 unresectable HCC(Barcelona Clinic Liver Cancer C)patients receiving pembrolizumab treatment were retrospectively reviewed.Overall survival(OS)was the primary endpoint,while objective response rate(ORR),disease control rate(DCR),and time to progression(TTP)were secondary evaluation indexes.We assessed demographics,irAEs,and outcomes by retrospective review.RESULTS One hundred and forty-three males and 47 females were included in the study.The ORR and DCR were 12.1%(23/190)and 52.1%(99/190),respectively.The median OS was 376 d[95%confidence interval(CI):340-411 d]and the median TTP was 98 d(95%CI:75-124 d).The overall incidence of treatment-related adverse events was 72.6%(138/190)and 10.0%of them were severe irAEs(grade≥3).Child-Pugh B class,portal vein tumor thrombus,extrahepatic metastasis,and hypothyroidism were the independent risk factors for survival.Patients with hypothyroidism showed a longer OS[517 d(95%CI:423-562)vs 431 d(95%CI:412-485),P=0.011]and TTP[125 d(95%CI:89-154)vs 87 d(95%CI:61-98),P=0.004]than those without irAEs.CONCLUSION Pembrolizumab-treated patients with unresectable HCC who experienced hypothyroidism have promising ORR and durable response.Hypothyroidism,an irAE,may be used as a clinical evaluation parameter of response to ICIs in unresectable HCC.

文摘[Objectives] The study aims to improve the ability of inspectors to recognize humoral morphology and provide data reference for the improvement of EQA work of humoral morphology by Guangxi Clinical Laboratory Center. [Methods] A retrospective analysis was made on the EQA of humoral morphology by Guangxi Clinical Laboratory Center from 2010 to 2022, and the number of participating laboratories, the rate of return, sample types and maps of EQA of humoral morphology such as urine sediment, vaginal secretions and so on(except feces), and the reasons for the high error rate of the results of the participating laboratories were analyzed. [Results] The number of laboratories participating in the assessment of humoral morphology increased from 98 in 2010 to 371 in 2022. Except for 2011(90.98%), the rate of return was more than 94%, and the highest rate of return was up to 100%. A total of 119 pictures of EQA of humoral morphology were studied, including 101 urine sediment smears, 13 vaginal secretions smears and 5 other smears. The types of specimens were relatively comprehensive. The distribution of the maps was basically reasonable. The urinary sediment was mainly composed of crystalline salts, followed by tubes, and cells and fungi ranked third. The coverage was relatively complete. The error rate of return results from high to low were bacteria(error rate was equal to 40%), tubes and crystalline salts(error rate was close to 29%), and cells and fungi(error rate was about 14%). The main cases with high error rate of return results are as follows: the difference between different tubes was not clear, and the diversity of crystal morphology was not understood enough;the phase division of cells in the same system was wrong. [Conclusions] The analysis and summary of the reasons for the high error rate of the data and results of Guangxi's EQA of humoral morphology is helpful for laboratory physicians to improve their awareness of morphological examination and identify clearly the error type and blurred concept, and lays a foundation for Guangxi Clinical Laboratory Center to carry out EQA of humoral morphology more specifically.
文摘BACKGROUND Alpha-1 antitrypsin deficiency is a rare genetic disease and a leading cause of inherited alterations in plasma protein metabolism(APPM).AIM To understand the prevalence,burden and progression of liver disease in patients with APPM including alpha-1 antitrypsin deficiency.METHODS We conducted a retrospective analysis of anonymized patient-level claims data from a German health insurance provider(AOK PLUS).The APPM cohort comprised patients with APPM(identified using the German Modification of the International Classification of Diseases-10th Revision[ICD-10-GM]code E88.0 between 01/01/2010-30/09/2020)and incident liver disease(ICD-10-GM codes K74,K70.2-3 and K71.7 between 01/01/2012-30/09/2020).The control cohort comprised patients without APPM but with incident liver disease.Outcomes were incidence/prevalence of liver disease in patients with APPM,demographics/baseline characteristics,diagnostic procedures,progression-free survival(PFS),disease progression and mortality.RESULTS Overall,2680 and 26299 patients were included in the APPM(fibrosis,96;cirrhosis,2584)and control(fibrosis,1444;cirrhosis,24855)cohorts,respectively.Per 100000 individuals,annual incidence and prevalence of APPM and liver disease was 10-15 and 36-51,respectively.In the APPM cohort,median survival was 4.7 years[95%confidence interval(CI):3.5-7.0]and 2.5 years(95%CI:2.3-2.8)in patients with fibrosis and cirrhosis,respectively.A higher proportion of patients in the APPM cohort experienced disease progression(92.0%)compared with the control cohort(67.2%).Median PFS was shorter in the APPM cohort(0.9 years,95%CI:0.7-1.1)compared with the control cohort(3.7 years,95%CI:3.6-3.8;P<0.001).Patients with cirrhosis in the control cohort had longer event-free survival for ascites,hepatic encephalopathy,hepatic failure and esophageal/gastric varices than patients with cirrhosis in the APPM cohort(P<0.001).Patients with fibrosis in the control cohort had longer event-free survival for ascites,cirrhosis,hepatic failure and esophageal/gastric varices than patients with fibrosis in the APPM cohort(P<0.001).In the APPM cohort,the most common diagnostic procedures within 12 mo after the first diagnosis of liver disease were imaging procedures(66.3%)and laboratory tests(51.0%).CONCLUSION Among patients with liver disease,those with APPM experience substantial burden and earlier liver disease progression than patients without APPM.
文摘BACKGROUND Risk stratification for patients with gastric precancerous lesions for endoscopic surveillance remains controversial.AIM To analysis of patients having developed gastric adenocarcinoma during the period of follow-up.METHODS We conducted a retrospective study on patients having undergone upper endoscopy prior to the development of gastric adenocarcinoma. The presence and stage of precancerous lesions as well as subtype of intestinal metaplasia at the baseline endoscopy got evaluated. Literature mini-review was performed.RESULTS Out of 1681 subjects in the Biobank, gastric adenocarcinoma was detected in five cases in whom previous endoscopy data with biopsies either from the corpus or antral part were available. All of the patients had incomplete intestinal metaplasia during the baseline endoscopy;all three subjects in whom intestinal metaplasia subtyping was performed according to Filipe et al, had Type Ⅲ intestinal metaplasia. Two of the five cases had low Operative Link on Gastritis Assessment(OLGA) and Operative Link on Gastritis Intestinal Metaplasia Assessment(OLGIM) stages(Ⅰ-Ⅱ) at the baseline.CONCLUSION The presence of incomplete intestinal metaplasia, in particular, that of Type Ⅲ is a better predictor for gastric adenocarcinoma development than OLGA/OLGIM staging system. Subtyping of intestinal metaplasia have an important role in the risk stratification for surveillance decisions.
文摘BACKGROUND Most physicians consider molars with chronic apical periodontitis(CAP)lesions as contraindications for immediate implant placement.At the patient’s request,we perform immediate implant placement of the mandibular molars with CAP in clinical practice.AIM To retrospectively analyze and compare the 5-year outcomes of immediate implant placement of the mandibular molars with CAP and those without obvious inflammation.METHODS The clinical data of patients with immediate implant placement of the mandibular molars in the Department of Oral and Maxillofacial Surgery,the Affiliated Hospital of Qingdao University,from June 2015 to June 2017 were collected.The patients were divided into CAP(n=52)and no-CAP(n=45)groups.Changes in bone mineral density and bone mass around implants were analyzed 5 years after implant restoration.RESULTS At 5 years after implantation,the peri-implant bone mineral density was 528.2±78.8 Hounsfield unit(HU)in the CAP group and 562.6±82.9 HU in the no-CAP group(P=0.126).Marginal bone resorption around implants did not differ significantly between the two groups,including buccal(P=0.268)or lingual(P=0.526)resorption in the vertical direction or buccal(P=0.428)or lingual(P=0.560)resorption in the horizontal direction.Changes in the peri-implant jump space did not differ significantly between the two groups,including the buccal(P=0.247)or lingual(P=0.604)space in the vertical direction or buccal(P=0.527)or lingual(P=0.707)space in the horizontal direction.The gray value of cone-beam computed tomography measured using Image J software can reflect the bone mineral density.In the CAP area,the gray values of the bone tissue immediately and 5 years after implant placement differed significantly from those of the surrounding bone tissue(P<0.01).CONCLUSION The results of this study suggest that immediate implant placement of the mandibular molars with CAP can achieve satisfactory 5-year clinical results,without significant differences in the complications,survival rate,or bone tissue condition from the no-CAP mandibular molars.

文摘Background:To investigate the clinical medication approach of Professor Guiqi Xuan(Prof.Xuan)in treating pediatric patients with attention-deficit hyperactivity disorder(ADHD)and the potential mechanism of the core herbal prescription.Methods:Following medical record information pretreatment,the Traditional Chinese Medicine(TCM)inheritance computing platform system V3.0 was utilized to analyze the standardized data.The associate rules were summarized to identify the core prescription for treating ADHD.The extracted core herbal prescription’s active compounds and potential targets were used to establish a protein-protein interaction network of active ingredient-disease targets.Cytoscape 3.9.1 software was used to analyze the network’s topological parameters to obtain the key active ingredients and their targets.The Bioconductor data package of R4.0.2 was used to analyze the gene ontology biological functions and Kyoto Encyclopedia of Genes and Genomes pathways of key targets.Results:Two hundred and twenty-seven entries derived from TCM record information were selected.Through data mining,it was found that 62.5%of pediatric patients had short-tempered behavior,nearly half had sleep problems,and 30%-40%had picky eating and polyphagia issues.The highest-frequency syndrome type was kidney deficiency and liver hyperactivity.Deficiency,fire,phlegm,and dyspeptic food were the main pathological factors for ADHD.Prof.Xuan’s treatment of ADHD mainly focused on replenishing kidney essence and subduing Yang(active,external,ascending,warm,bright,functional and excited pertain to Yang).The core herbal prescription for ADHD included Yuan-zhi,Yi-zhi,Gui-jia,Bai-shao,Long-chi,Ci-shi,Shi-chang-pu,Yu-jin,Fu-shen,and Huang-jing.The protein-protein interaction network showed that MAOA,ADRB2,FOS,MAOB,and SLC6A3 were the five key targets essential in treating ADHD with core herbal prescriptions.The gene ontology biological function of crucial targets mainly involved G protein-coupled amine receptor activity,catecholamine binding,and neurotransmitter transmembrane transporter activity.Analysis of Kyoto Encyclopedia of Genes and Genomes pathways showed that the dopaminergic synapse signaling and neuroactive ligand-receptor interaction pathways were significantly enriched and may be the primary routes for the main treatment of ADHD.Conclusion:Prof.Xuan’s treatment of ADHD has achieved satisfactory clinical effects by supplementing the kidney,replenishing the essence,opening the orifices,nourishing the Yin(static,internal,descending,cold,dim,organic,depressed and pertain to Yin),and subduing the Yang.The major prescription predominantly affects catecholamine binding,neuroactive ligand-receptor interaction,G protein-coupled amine receptor function,and signaling pathways for dopaminergic synapses.Our findings showed that the methodology and software used in this research could explore and analyze the mechanism behind Prof.Xuan’s clinical medication rule for treating ADHD in children.
