The Prognostic Value of Pathological and Molecular Margins Marked by p53 and eIF4E in Laryngeal Carcinoma

Objective: To study the prognostic value of the pathological margin and molecular margin marked by eIF4E and P53 protein in laryngeal carcinoma. Methods: The prognostic value of pathological and molecular margin was studied in 253 cases and 67 cases respectively, the latter were pathological negative margin chosen from the former. Immunohistochemisty was used to detect the expression of eIF4E and p53 proteins. Results: The rate of pathological, p53 and eIF4E positive margins was 20.2%, 19.4% and 32.8% respectively. The recurrent rate of those with positive margins was higher than that of negative margins, which including pathological margin (70.6% vs 35.1%, P =0.0000), p53 margin (69.2% vs 33.3%, P =0.018) and eIF4E margin (63.6% vs 28.9%, P =0.018); The survival rate of those with negative margins was higher than those with positive margins, including pathological margin (the 5-year cumulative survival rate was 37.52% and 64.37% respectively, P =0.0023), p53 margin (the 5-year cumulative survival rate was 24.62% and 75.69% respectively, P =0.0012) and eIF4E margin (the 5-year cumulative survival rate was 43.31% and 77.52% respectively, P =0.0006). Conclusion: The prognosis of those with both pathological and molecular positive margins was worse than that of the negative margins; Both the eIF4E and p53 were useful markers to pick out the poor prognostic patients from those with pathological negative margin, and the former seemed to be more potential.

Caregiver burden:A concept analysis

Objective:Caregiver burden is used frequently within the nursing literature.It has not yet been clearly defined as there are different opinions regarding this concept.The purpose of this paper is to provide clarity surrounding the concept caregiver burden.Methods:An electronic search of MEDLINE,CINAHL,Health Source Nursing/Academic Edition and Academic Search Complete(ASC)of EBSCO,China National Knowledge Infrastructure(CNKI)and Google Scholar were searched with a limit of 10 years and published in the English or Chinese language.The paper adopted the framework by Walker and Avant.The attributes,antecedents,consequences and uses of the concept were identified.Results:At total of 33 articles were included.The three attributes of caregiver burden were identified as self-perception,multifaceted strain,and over time.The antecedents included insufficient financial resources,multiple responsibility conflict,lack of social activities.The consequences of caregiver burden resulted in negative change which included decreased care provision,decrease in quality of life,physical and psychological health deterioration.Conclusion:A definition of caregiver burden was developed.Tools to measure caregiver burden were identified.The findings from this analysis can be used in nursing practice,nursing education,research and administration.

Prevalence of and risk factors for postprandial hypotension in older Chinese men

Objective To assess the prevalence of and risk factors for postprandial hypotension （PPH） among old and very old Chinese men. Methods The study included 349 Chinese men aged 65 and older, grouped into two age categories： group 1 （old） included 163 men aged 65 to 80 years; group 2 （very old） included 186 men aged over 80 years. Blood pressure changes after meals were assessed every 15 min by ambulatory blood pressure monitoring. Symptoms after meal ingestion and after standing up and changes in the baseline condition relative to blood pressure changes were observed continuously. Additional baseline data included body mass index, medical history, and medication use Results The prevalence of PPH was 59.3% overall and was significantly higher in group 2 than group 1 （63.4% vs. 54.6%, P 〈 0.05）. In group 2, the prevalence of PPH after breakfast （33.8%） and lunch （32.1%） were higher than that after supper （20.9%）, P 〈 0.05. Hypertension and age were significant risk factors for PPH （OR = 2.188, 95% CI： 1.134-4.223, P = 0.02; OR = 1.86, 95% CI： 1.112-3.11, P = 0.018, respectively）. In contrast, acarbose use was protective against PPH （OR = 0.4, 95% CI： 0.189-0.847, P = 0.017）. The decrease in blood pres- sure during PPH was 20-40 mmHg and the maximum was 90 mmHg. PPH usually occurred at 30-60 min after a meal and lasted 30-120 rnin. Conclusions These findings demonstrate that the prevalence of PPH in men aged over 80 years is significantly higher than those in men aged 65 to 80 years, and the blood pressure decline is also higher for men aged over 80 years. In addition, hypertension and age were main risk factors for PPH in the older men, which suggest that preventing and treating PPH is worthwhile.

Food-borne parasitic zoonosis: Distribution of trichinosis in Thailand

Trichinosis is among the most common food-borne parasitic zoonoses in Thailand and many outbreaks are reported each year. This paper investigates the distribution of the disease in regions of north, north-east, central and south Thailand. Between the earliest recorded of outbreak of trichinosis in Mae Hong Son Province in 1962 and 2006, there have been 135 outbreaks involving 7340 patients and 97 deaths in Thailand. The highest number of cases, 557, was recorded in 1983. Most infected patients were in the 35-44 year age group, and the disease occurred more frequently in men than women during 1962-2003, with no significant sex difference during 2004-2006. Outbreaks were most common in the northern areas, especially in rural areas where raw and under-cooked pork and/or wild animals are eaten. Human infections occur annually in northern Thailand during communal feasts celebrating the Thai New Year. Trichinosis causes have been reported every year, supporting the need for planning education programs.

Prevalence of depressive and anxiety disorders in Chinese gastroenterological outpatients

AIM:To investigate the prevalence and physicians' detection rate of depressive and anxiety disorders in gastrointestinal(GI)outpatients across China. METHODS:A hospital-based cross-sectional survey was conducted in the GI outpatient departments of 13 general hospitals.A total of 1995 GI outpatients were recruited and screened with the Hospital Anxiety and Depression Scale(HADS).The physicians of the GI departments performed routine clinical diagnosis and management without knowing the HADS score results.Subjects with HADS scores≥8 were subsequently interviewed by psychiatrists using the Mini International Neuropsy-chiatric Interview(MINI)to make further diagnoses. RESULTS:There were 1059 patients with HADS score ≥8 and 674(63.64%)of them undertook the MINI interview by psychiatrists.Based on the criteria of Diagnostic and Statistical Manual of Mental Disorders (4th edition),the adjusted current prevalence for depressive disorders,anxiety disorders,and comorbidity of both disorders in the GI outpatients was 14.39%, 9.42%and 4.66%,respectively.Prevalence of depressive disorders with suicidal problems[suicide attempt or suicide-related ideation prior or current;module C (suicide)of MINI score≥1]was 5.84%in women and 1.64%in men.The GI physicians'detection rate of depressive and anxiety disorders accounted for 4.14%. CONCLUSION:While the prevalence of depressive and anxiety disorders is high in Chinese GI outpatients, the detection rate of depressive and anxiety disorders by physicians is low.

Protective effect of alcohol consumption for fatty liver but not metabolic syndrome

AIM:To investigate the effect of alcohol on the metabolic syndrome (MS) and fatty liver in Japanese men and women.METHODS:A cross-sectional study was conducted in a medical health checkup program at a general hospital.This study involved 18 571 Japanese men and women,18-88 years of age,with a mean body mass index of 22.6 kg/m 2.A standardized questionnaire was administered.The total amount of alcohol consumed per week was calculated,and categorized into four grades.Fatty liver was examined by ultrasound modified criteria of the revised National Cholesterol Educa-tion Program Adult Treatment Panel Ⅲ and the new International Diabetes Federation.RESULTS:The prevalence of fatty liver decreased in men and women with light to moderate alcohol consumption,whereas the prevalence of MS was not so changed.The prevalence of fatty liver of any grade in men was lower than that in those with no or minimal alcohol consumption.In women with light to moderate alcohol consumption,prevalence of fatty liver was lower than that in women with no or minimal alcohol consumption.By logistic regression analysis,the odds ratio (OR) for MS in women with light alcohol consumption was decreased to < 1.0,but this change was not clear in men.The OR for fatty liver was clearly < 1.0 in men with any level of alcohol consumption and in women with light to moderate consumption.CONCLUSION:Light to moderate alcohol consumption has a favorable effect for fatty liver,but not for MS in Japanese men and women.

Does antecolic reconstruction decrease delayed gastric emptying after pancreatoduodenectomy?

Delayed gastric emptying(DGE) is a frequent complication after pylorus-preserving pancreatoduodenectomy(PpPD).Kawai and colleagues proposed pylorus-resecting pancreatoduodenectomy(PrPD) with antecolic gastrojejunal anastomosis to obviate DGE occurring after PpPD.Here we debate the reported differences in the prevalence of DGE in antecolic and retrocolic gastro/duodeno-jejunostomies after PrPD and PpPD,respectively.We concluded that the route of the gastro/duodeno-jejunal anastomosis with respect to the transverse colon;i.e.,antecolic route or retrocolic route,is not responsible for the differences in prevalence of DGE after pancreatoduodenectomy(PD) and that the impact of the reconstructive method on DGE is related mostly to the angulation or torsion of the gastro/duodeno-jejunostomy.We report a prevalence of 8.9% grade A DGE and 1.1% grade C DGE in a series of 89 subtotal stomach-preserving PDs with Roux-en Y retrocolic reconstruction with anastomosis of the isolated Roux limb to the stomach and single Roux limb to both the pancreatic stump and hepatic duct.Retrocolic anastomosis of the isolated first jejunal loop to the gastric remnant allows outflow of the gastric contents by gravity through a "straight route".

Hepatic echinococcosis:Clinical and therapeutic aspects

Echinococcosis or hydatid disease （HD） is a zoonosis caused by the larval stages of taeniid cestodes belong- ing to the genus Echinococcus. Hepatic echinococcosis is a life-threatening disease, mainly differentiated into alveolar and cystic forms, associated with Echinoc- cus multilocularis （E. multi/ocular/s） and Echinococcus granulosus （E. granulosus） infection, respectively. Cys- tic echinococcosis （CE） has a worldwide distribution, while hepatic alveolar echinococcosis （AE） is endemic in the Northern hemisphere, including North America and several Asian and European countries, like France, Germany and Austria. E. granulosus young cysts are spherical, unilocular vesicles, consisting of an internal germinal layer and an outer acellular layer. Cyst expansion is associated with a host immune reaction and the subsequent development of a fibrous layer, called the per/cyst; old cysts typically present internal septa- tions and daughter cysts. E. multilocularis has a tumor-like, infiltrative behavior, which is responsible for tissue destruction and finally for liver failure. The liver is the main site of HD involvement, for both alveolar and cystic hydatidosis. HD is usually asymptomatic for a long period of time, because cyst growth is commonly slow; the most frequent symptoms are fatigue and abdominal pain. Patients may also present jaundice, hepatomegaly or anaphylaxis, due to cyst leakage or rupture. HD diagnosis is usually accomplished with the combined use of ultrasonography and immunodiagnosis; furthermore, the improvement of surgical techniques, the introduction of minimally invasive treatments [such as puncture, aspiration, injection, re-aspiration （PAIR）] and more effective drugs （such as benzoimidazoles） have deeply changed life expectancy and quality of life of patients with HD. The aim of this article is to provide an up-to-date review of biological, diagnostic, clinical and therapeutic aspects of hepatic echinococcosis.

Severe acute pancreatitis in the elderly: Etiology and clinical characteristics

AIM: To investigate the etiology and clinical characteristics of severe acute pancreatitis (SAP) in elderly patients (≥ 60 years of age). METHODS: We reviewed retrospectively all the SAP cases treated in Xuanwu Hospital in Beijing between 2000 and 2007. RESULTS: In 169 patients with SAP, 94 were elderly and 16 died. Biliary and idiopathic etiologies were the first two causes that accounted for over 90% of SAP in the elderly. Biliary, hyperlipemic and alcoholic etiologies were the first three causes in the young. The proportion of co- morbidity of cholelithiasis, biliary infection, hypertension and coronary heart disease in the aged was significantly higher than that in their young partners. The scores of APACHE Ⅱ and Ranson were also significantly higher in the elderly except the CT score. Organ failures were more common in the elderly, but the local pancreatic complications were not different between the two groups. Mortality of the aged was correlated with the severity of SAP, multiple co-morbidity and incidence of multiple organ dysfunction syndrome (MODS). MODS was the main cause of death. CONCLUSION: The etiology of SAP in the elderly is quite different from that in the young. Biliary and unknown factors are main causes in the aged. The elderly are subject to major organ failures but there is no difference in the occurrence of local pancreatic complications between the elderly and the young. It is crucial to monitor and improve the functions of major organs so as to prevent MODS in the aged with SAP.

NAT2 polymorphism in Omani gastric cancer patients-risk predisposition and clinicopathological associations

AIM： To study whether N-acetyltransferase 2 （NAT2） genotypes and phenotypes are associated with increased risk factor for gastric cancer in Omani patients and to study the clinico-pathological correlations and the prognostic significance of NAT2. METHODS： Genomic DNA was extracted from peripheral blood of 100 gastric cancer patients and 100 control subjects. NAT2 genotyping was performed using DNA sequencing. The prognostic significance of NAT2 and other clinicopathological features was assessed by univariate and multivariate analyses. RESULTS： We observed no significant association between NAT2 genotypes and phenotypes and gastric cancer risk. The IVAT2 phenotype polymorphisms and gastric cancer risk predisposition were not modified by concomitant Hpylori infection and smoking. There was no significant association between NAT2 and clinicopathological features, and NAT2 had no independent prognostic significance. CONCLUSION： In the current study, NAT2 genotypes and phenotypes are not associated with gastric cancer risk predisposition. Moreover NAT2 phenotypes had no clinicopathological associations or prognostic significance.

High prevalence of aspirin resistance in elderly patients with cardiovascular disease and metabolic syndrome

Background Metabolic syndrome is known to be a prothrombotic state. We undertook this study to examine a hypothesis that aspirin resistance may be associated with metabolic syndrome, and to assess other potential determinants of aspirin resistance in patients with cardiovascular disease （CVD）. Methods A total of 469 elderly patients with CVD were recruited. One hundred and seventy-two patients with metabolic syndrome and 297 without metabolic syndrome （control group） received daily aspirin therapy （〉 75 mg） over one month. Platelet aggregation was measured by light transmission aggregometry （LTA）. Aspirin resistance was defined as 〉 20% arachidonic acid （AA）- and 〉 70% adenosine diphosphate （ADP）-induced aggregation according to LTA. Aspirin semi-responders were defined as meeting one （but not both） of these criteria. Results By LTA, 38 of 469 （8.1%） patients were aspirin resistant. The prevalence of aspirin resistance was higher in the metabolic syndrome group compared with the control group [11.6 % vs. 6.6%, odds ratio （OR） = 2.039; 95% confidence interval （CI）： 1.047-3.973]. In the multivariate logistic regression analysis, metabolic syndrome （OR = 4.951, 95% CI： 1.440-17.019, P = 0.011） was a significant risk factor for aspirin resistance. Conclusions A significant number of patients with CVD and metabolic syndrome are resistant to aspirin therapy. This might further increase the risk of cardiovascular morbidity and mortality in these patients.

Investigation of the effect of military stress on the prevalence of functional bowel disorders

AIM: To investigate the morbidity of functional bowel disorders (FBD) under military stress conditions in order to lay foundations for the prevention and treatment of this disease. METHODS: Four hundred and fifty-seven soldiers who were assigned to specified services and 471 soldiers who were assigned to routine services were enrolled using cluster sampling, with the latter as a control group. They were surveyed using the Rome Ⅲ FBD standard questionnaire. The FBD symptom question-naire included FBD-related symptoms, severity, dura- tion or attack time, and accompanying symptoms. RESULTS: The morbidity of the military stress group (14.6%) was significantly higher than in the control group (9.98%) ( 2 = 4.585, P < 0.05). The incidence of smoking, abdominal pain and acid regurgitation ( 2 = 4.761, P < 0.05) as well as the ZUNG anxiety/depression scores ( 2 = 7.982, P < 0.01) were also sig- nificantly higher in the military stress group compared with the control group. ZUNG anxiety ( 2 = 11.523, P < 0.01) and depression ( 2 = 5.149, P < 0.05) scores were higher in the FBD group compared with the non-FBD group. The differences in the ZUNG self-rated anxiety and depression scales between the 2 groups were statistically significant ( 2 = 14.482, P < 0.01 and 2 = 6.176, P < 0.05). CONCLUSION: The morbidity of FBD was higher under military stress conditions.

Worldwide epidemiology of liver hydatidosis including the Mediterranean area

The worldwide incidence and prevalence of cystic echinococcosis have fallen dramatically over the past several decades.Nonetheless,infection with Echinococcus granulosus(E.granulosus)remains a major public health issue in several countries and regions,even in places where it was previously at low levels,as a result of a reduction of control programmes due to economic problems and lack of resources.Geographic distribution differs by country and region depending on the presence in that country of large numbers of nomadic or semi-nomadic sheep and goat flocks that represent the intermediate host of the parasite,and their close contact with the final host,the dog,which mostly provides the transmission of infection to humans.The greatest prevalence of cystic echinococcosis in human and animal hosts is found in countries of the temperate zones,including several parts of Eurasia(the Mediterranean regions,southern and central parts of Russia,central Asia,China),Australia,some parts of America(especially South America)and north and east Africa.Echinococcosis is currently considered an endemic zoonotic disease in the Mediterranean region.The most frequent strain associated with human cystic echinococcosis appears to be the common sheep strain(G1).This strain appears to be widely distributed in all continents.The purpose of this review is to examine the distribution of E.granulosus and the epidemiology of a re-emerging disease such as cystic echinococcosis.

Prevalence of cardiovascular disease in subjects hospitalized due to chronic obstructive pulmonary disease in Beijing from 2000 to 2010

Objectives To investigate the overall prevalence of cardiovascular disease （CVD） in subjects hospitalized for chronic obstructive pulmonary disease （COPD）,and explore the prevalence of the major CVD complications and trends in patients with COPD over a 10-year period.Methods Medical records in the PLA General Hospital,Beijing Union Medical College Hospital,and Beijing Hospital from 2000/01/01 to 2010/03/03 were retrospectively reviewed.A total of 4960 patients with COPD were reviewed in the study （3570 males,mean age,72.2 ± 10.5 years; 1390 females,mean age,72.0 ± 10.4 years）.Results The prevalence of CVD in COPD patients was 51.7％.The three most prevalent CVDs were ischemic heart disease （28.9％）,heart failure （19.6％）,and arrhythmia （12.6％）.During the 10-year study period,the prevalence of various CVDs in COPD patients showed a gradual increasing trend with increasing age.There was higher morbidity due to ischemic heart disease （P ＜ 0.01） in male COPD patients than in the female counterparts.However,heart failure （P ＜ 0.01）and hypertension （P ＜ 0.01） occurred less frequently in male COPD patients than in female COPD patients.Furthermore,the prevalence of ischemic heart disease decreased year by year.In addition to heart failure,various types of CVD complications in COPD patients tended to occur in younger subjects.The prevalence of all major types of CVD in women tended to increase year by year.Conclusions The prevalence of CVD in patients hospitalized for COPD in Beijing was high.Age,sex and CVD trends,as well as life style changes,should be considered when prevention and control strategies are formulated.

Barrett's esophagus:Prevalence and risk factors in patients with chronic GERD in Upper Egypt

AIM： To determine the prevalence and possible risk factors of Barrett＇s esophagus （BE） in patients with chronic gastroesophageal reflux disease （GERD） in EI Minya and Assuit, Upper Egypt. METHODS： One thousand consecutive patients with chronic GERD symptoms were included in the study over 2 years. They were subjected to history taking including a questionnaire for GERD symptoms, clinical examination and upper digestive tract endoscopy. Endoscopic signs suggestive of columnar-lined esophagus （CLE） were defined as mucosal tongues or an upward shift of the squamocolumnar junction. BF was diagnosed by pathological examination when specialized intestinal metaplasia was detected histologically in suspected CLE. pH was monitored in 40 patients. RESULTS： BE was present in 7.3% of patients with chronic GERD symptoms, with a mean age of 48.3 ± 8.2 years, which was significantly higher than patients with GERD without BE （37.4 ± 13.6 years）. Adenocarcinoma was detected in eight cases （0.8%）, six of them in BE patients. There was no significant difference between patients with BE and GERD regarding sex, smoking, alcohol consumption or symptoms of GERD. Patients with BE had significantly longer esophageal acid exposure time in the supine position, measured by pH monitoring. CONCLUSION： The prevalence of BE in patients with GERD who were referred for endoscopy was 7.3%. BE seems to be associated with older age and more in patients with nocturnal gastroesophageal reflux.

Prevalence,predictors,and clinical consequences of medical adherence in IBD:How to improve it?

Inflammatory bowel diseases(IBD)are chronic diseases with a relapsing-remitting disease course necessitating lifelong treatment.However,non-adherence has been reported in over 40%of patients,especially those in remission taking maintenance therapies for IBD. The economical impact of non-adherence to medical therapy including absenteeism,hospitalization risk, and the health care costs in chronic conditions,is enormous.The causes of medication non-adherence are complex,where the patient-doctor relationship, treatment regimen,and other disease-related factors play key roles.Moreover,subjective assessment might underestimate adherence.Poor adherence may result in more frequent relapses,a disabling disease course, in ulcerative colitis,and an increased risk for colorectal cancer.Improving medication adherence in patients is an important challenge for physicians.Understanding the different patient types,the reasons given by patients for non-adherence,simpler and more convenient dosage regimens,dynamic communication within the health care team,a self-management package incorporating enhanced patient education and physician-patient interaction,and identifying the predictors of nonadherence will help devise suitable plans to optimize patient adherence.This editorial summarizes the available literature on frequency,predictors,clinical consequences,and strategies for improving medical adherence in patients with IBD.

Heart failure in the elderly

Heart failure （HF） is a major public health problem worldwide entailing high morbidity and mortality as well as high costs. This chronic syndrome associates with a low functional status and quality of life. Most patients with HF are elderly, constituting up to 80% of patients suffering from this disease with both incidence and prevalence of the condition increasing with age. This is due to the progressive aging of the population as well as improved and better survival after cardiac insults, such as myocardial infarction,
