Selected AbstractsMTHFR C677T Polymorphism and Risk of HCC in Patients With Liver Cirrhosis: Role of Male Gender and Alcohol ConsumptionALCOHOLISM, Issue 1 2009Carlo Fabris Background:, A single nucleotide polymorphism (SNP) C677T in the methylenetetrahydrofolate reductase (MTHFR) gene has been identified. The TT or CT genotypes show a marked reduction of the enzyme activity; this causes higher homocysteine levels and alterations of folate metabolism. Folate metabolism is essential for DNA synthesis and methylation, crucial steps in carcinogenesis. In this paper, we investigated whether the MTHFR C677T SNP could influence the occurrence of hepatocellular carcinoma (HCC) in a cohort of patients transplanted for end stage liver disease of different etiologies. Methods:, Two hundred and twelve consecutive patients who underwent liver transplantation for end stage liver disease due to hepatitis B or C, alcoholic liver disease, and other causes were studied. Two hundred and thirty-six blood donors served as controls. Focal hepatic lesions were searched in the sectioned explanted livers. The presence of the MTHFR C677T SNP was determined via polymerase chain reaction amplification. Results:, Among the 65 patients with HCC, 22 had the CC genotype, 30 the CT, and 13 the TT genotype. Only in patients with alcoholic liver disease was a significant association detected between the TT genotype and the presence of liver cancer (6/17 vs. 5/46, p < 0.05). At stepwise logistic regression analysis the independent selected predictors of HCC were found: age at transplantation >55 years (p < 0.001) and the association among male gender, alcoholic liver disease, and MTHFR TT genotype (p = 0.002). Conclusions:, The present study suggests that male TT carriers with alcoholic cirrhosis bear an increased risk of developing HCC. [source] Prevalence and correlates of traumatic brain injury among delinquent youthsCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 4 2008Brian E. Perron Background,Delinquent youth frequently exhibit high-risk behaviours that can result in serious injury. However, little is known about traumatic brain injuries (TBIs) and their correlates in this population. Aims,To examine the period prevalence and correlates of TBIs in delinquent youths. Method,Interviews were conducted with 720 (97.3%) residents of 27 Missouri Division of Youth Services rehabilitation facilities between March 1 and May 31, 2003. Participants [mean age (Mage) = 15.5, standard deviation (SD) = 1.2, 87% male] completed measures assessing TBI, substance use, psychiatric symptoms, and antisocial traits/behaviours. TBI was defined as ever having sustained a head injury causing unconsciousness for more than 20 minutes. Results,Nearly one-in-five youths (18.3%) reported a lifetime TBI. Youths with TBIs were significantly more likely than youths without to be male, have received a psychiatric diagnosis, report an earlier onset of criminal behaviour/substance use and more lifetime substance use problems and past-year criminal acts, evidence psychiatric symptoms, report lifetime suicidality, be impulsive, fearless, and external in locus of control and criminally victimized in the year preceding incarceration. Male gender and frequency of own criminal victimization were important predictors of TBI in multivariate analyses. Regression analyses adjusted for demographic factors, indicated that youths with TBIs were at significantly elevated risk for current depressive/anxious symptoms, antisocial behaviour, and substance abuse problems. Conclusions,TBI is common among delinquent youth and associated with wide ranging psychiatric dysfunction; however, the causal role of TBIs in the pathogenesis of co-morbid conditions remains unclear.

[source] Incidence, risk factors, and survival of hepatocellular carcinoma in primary biliary cirrhosis: Comparative analysis from two centers,HEPATOLOGY, Issue 4 2009Anna Cavazza The limited information and divergent results on the prevalence, incidence, and risk factors for hepatocellular carcinoma (HCC) in patients with primary biliary cirrhosis (PBC) may be due to the low prevalence of the disease and geographical and environmental differences. Therefore, we analyzed the incidence, prevalence, survival, and risk factors for HCC in patients with PBC from two European centers (389 from Barcelona, Spain, and 327 from Padova, Italy) followed up for 9.3 ± 6.5 years. Gender, age, smoking habit, alcohol consumption, presence of hepatitis B surface antigen (HBsAg) or hepatitis C virus antibodies (anti-HCV), and advanced histological stage (III-IV) were evaluated as risk factors for tumor development. Twenty-four patients (13 from Barcelona and 11 from Padova) developed HCC. The prevalence of HCC was similar in Barcelona (3.34%) and Padova (3.36%). The incidence was 0.35 and 0.37 per 100 patient-years, respectively. Male gender, age >52 years, smoking habit, alcohol >40 g/day, HBsAg, and anti-HCV were not associated with HCC. Advanced histological stage was the only factor associated with the development of HCC (odds ratio [OR]: 5.80, 95% confidence interval [CI]: 2.34-14.38, P < 0.001). When analyzing the two series separately, male gender was associated with higher likelihood of HCC in Padova (OR: 8.09, 95% CI: 1.93-33.8, P < 0.01). The median survival after the diagnosis of HCC was 36 months. Conclusion: The prevalence and incidence of HCC is similar in Spain and Italy and the advanced histological stage is the only risk factor associated with the development of HCC in PBC. The slight disparities observed between the two series might be explained by patient features on diagnosis of liver disease. (HEPATOLOGY 2009.) [source] Non-medically supervised treatment interruptions among participants in a universally accessible antiretroviral therapy programmeHIV MEDICINE, Issue 5 2010DM Moore Background We examined clinical outcomes, patient characteristics and trends over time of non-medically supervised treatment interruptions (TIs) from a free-of-charge antiretroviral therapy (ART) programme in British Columbia (BC), Canada. Methods Data from ART-naïve individuals ,18 years old who initiated triple combination highly active antiretroviral therapy (HAART) between January 2000 and June 2006 were analysed. Participants having ,3 month gap in HAART coverage were defined as having a TI. Cox proportional hazards modelling was used to examine factors associated with TIs and to examine factors associated with resumption of treatment. Results A total of 1707 participants were study eligible and 643 (37.7%) experienced TIs. TIs within 1 year of ART initiation decreased from 29% of individuals in 2000 to 19% in 2006 (P<0.001). TIs were independently associated with a history of injection drug use (IDU) (P=0.02), higher baseline CD4 cell counts (P<0.001), hepatitis C co-infection (P<0.001) and the use of nelfinavir (NFV) (P=0.04) or zidovudine (ZDV)/lamivudine (3TC) (P=0.009) in the primary HAART regimen. Male gender (P<0.001), older age (P<0.001), AIDS at baseline (P=0.008) and having a physician who had prescribed HAART to fewer patients (P=0.03) were protective against TIs. Four hundred and eighty-eight (71.9%) participants eventually restarted ART with male patients and those who developed an AIDS-defining illness prior to their TI more likely to restart therapy. Higher CD4 cell counts at the time of TI and unknown hepatitis C status were associated with a reduced likelihood of restarting ART. Conclusion Treatment interruptions were associated with younger, less ill, female and IDU participants. Most participants with interruptions eventually restarted therapy. Interruptions occurred less frequently in recent years. [source] How adherent to treatment with azathioprine are patients with Crohn's disease in long-term remission?INFLAMMATORY BOWEL DISEASES, Issue 4 2007Gerassimos J. Mantzaris MD Abstract Background: Patients with longstanding quiescent Crohn's disease on azathioprine usually maintain an excellent quality of life but are also concerned about long-term safety. This may affect adherence to treatment. The aim of the present study was to assess the adherence to azathioprine in a cohort of patients with Crohn's disease in long-term remission. Methods: Thirty patients with Crohn's disease in remission on azathioprine for ,48 months were enrolled in the study. All were asked to record the number of azathioprine tablets they consumed daily. Notes were kept every other month for 6 months. Adherence was defined as consumption of ,80% of medication. Results: Most patients (18/28, 74.3%) were not adherent to treatment. The mean (±SD) daily dose of azathioprine in adherent and nonadherent patients was 145 ± 45 mg and 102 ± 20 mg, respectively. However, there were no significant differences between the 2 groups in the mean IBDQ score and mean Crohn's Disease Activity Index (CDAI) score, both throughout the entire study and at each time point of the study. Male gender, single status, and consumption of >5 concomitant medications were associated with nonadherence. Conclusions: Most patients with Crohn's disease in longstanding remission had low self-reported adherence to azathioprine. Both male gender and single status were associated with nonadherence to azathioprine, whereas disease factors were not related to self-reported adherence. Patients considered nonadherent to treatment maintained disease remission and a quality of life similar to patients who were adherent to treatment. (Inflamm Bowel Dis 2006) [source] Sex-specific familial risks of urinary bladder cancer and associated neoplasms in SwedenINTERNATIONAL JOURNAL OF CANCER, Issue 9 2009Justo Lorenzo Bermejo Abstract Male gender and a family history of cancer are established risk factors for urinary bladder neoplasms. This study used the latest update of the Swedish Family-Cancer Database, which includes 42,255 bladder cancer patients, to investigate the sex-specific incidences and types of tumors in relatives of bladder cancer patients. Men with parents or siblings affected by lung cancer did not show an increased risk of bladder neoplasms. Among women, the familial association was restricted to daughters of women with lung cancer. Brothers showed higher risks than the sons of bladder cancer patients. Men older than 54 years were at an increased risk of bladder cancer only if their fathers or siblings were diagnosed after age 65 years. The present data indicated a limited contribution of smoking to the familial clustering of bladder cancer with other neoplasms. The dependence of the relative risks on the type of familial relationship probably reflected a heterogeneous character of familial aggregation. Age-specific results suggested differential risk factors for tumors diagnosed before 50 years of age versus neoplasms detected later in life. The present data may guide the design of forthcoming gene identification studies and the interpretation of the genome-wide association studies that are about to be published. © 2008 Wiley-Liss, Inc. [source] Verbal aggression in Alzheimer's disease.INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 9 2001Clinical, functional, neuropsychological correlates Abstract Objectives To determine the clinical, functional and neuropsychological correlates of verbal aggression in Alzheimer's disease in a group of consecutive first attendees to a memory clinic. Methods 150 people were evaluated and diagnosed as suffering with probable Alzheimer's disease. These people were tested using the Behave-AD for the presence of verbal aggression, delusions, depression and agitation. They were also assessed with cognitive, functional and neuropsychological scales. Results Twenty-eight per cent of this group of Alzheimer patients had exhibited some verbal aggression in the preceding month. Male gender (p,=,0.022), the presence of paranoid and delusional ideation (p,=,0.003) and agitation (p,=,0.042) were significantly associated with verbal aggression in a stepwise backward logistic regression analysis. Conclusion The presence of verbal aggression should prompt the clinician to search for delusional ideation, which may respond to phamacotherapy. Copyright © 2001 John Wiley & Sons, Ltd. [source] Risk factors for injuries to maxillary permanent incisors and upper lip among schoolchildren in Dar es Salaam, TanzaniaINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 2 2009FEBRONIA KOKULENGYA KAHABUKA Background.,, Dental trauma is common among children, and the maxillary permanent central incisors are the most often affected teeth. Aim.,, This study aimed to investigate the risk factors for injury to maxillary permanent incisors and the upper lip among Tanzanian schoolchildren aged 8,14 years. Design.,, A cross-sectional study involving 1119 children. The risk variables investigated included age, gender, lip competence, and overjet. The corresponding proportions of injuries and the relative risk (with 95% confidence interval) were calculated and tested by Fisher's exact test. Logistic regression was applied to ascertain the strength and direction of the association of the risk variables to injuries, and backward selection was used to test significant risk factors. Results.,, About 24% of the children had trauma to maxillary incisors, 45% had incompetent lip whereas 31% had increased overjet. Age, gender, overjet, and lip competence showed significant association with injuries to upper lip and maxillary incisors. Boys had sustained more injuries than girls, with a higher relative risk for luxation injuries. Enamel fracture was associated with overjet combined with lip competence, whereas enamel dentine fracture without pulp involvement was related to gender. Luxation injuries were associated with gender, tooth avulsion with overjet, and lip competence. Injury to the upper lip was associated with age. Conclusion.,, Male gender, increased overjet, and lip incompetence were the main risk factors of getting trauma to maxillary incisors, whereas age was the risk factor for injury to the upper lip. [source] Tooth loss during maintenance following periodontal treatment in a periodontal practice in NorwayJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 7 2004Øystein Fardal Abstract Background: Periodontal therapy coupled with careful maintenance has been shown to be effective in maintaining periodontal health; however, a small number of teeth are still lost because of progressive periodontitis. Aim: To investigate factors associated with tooth loss due to periodontal reasons during maintenance following periodontal treatment in patients in a Norwegian specialist periodontal practice. The study also examined how initial prognosis related to actual outcome as measured by periodontal tooth loss. Methods: Hundred consecutive patients (68 females, 32 males) who had comprehensive periodontal treatment and attended for 9.8 (SD: 0.7), range: 9,11 years of maintenance care, were studied. All teeth classified as being lost due to periodontal disease over the period were identified. Results: Only 36 (1.5%) of the 2436 teeth present at baseline were subsequently lost due to periodontal disease. There were 26 patients who lost at least one tooth. Logistic regression analysis showed that tooth loss was significantly related to male gender (p=0.049; adjusted odds ratio: 2.8; confidence interval (c.i.): 1.0,8.1), older age, i.e.>60 years (p=0.012; adjusted odds ratio: 4.0; c.i.: 1.3,12.0) and smoking (p=0.019; adjusted odds ratio: 4.2; c.i.: 1.4,13.8). The majority 27 (75%) of the teeth lost due to periodontal disease had been assigned an uncertain, poor or hopeless initial prognosis; however, nine teeth (25%) lost had been assigned a good prognosis at baseline. The prognosis for 202 teeth was judged to have worsened over the period of the study. Conclusion: Compliance with maintenance following periodontal treatment was associated with very low levels of tooth loss in a referral practice in rural Norway. Male gender, older age (>60 years) and smoking were predictors of tooth loss due to progressive periodontitis. [source] Human leukocyte antigen-DRB1*1101 correlates with less severe hepatitis in Taiwanese male carriers of hepatitis B virus,JOURNAL OF MEDICAL VIROLOGY, Issue 4 2009Yi-Wen Huang Abstract Human leukocyte antigen (HLA) class II molecules are associated with host immune responses against hepatitis B virus infection. Male gender is the apparent host factor when someone encounters with the severity of hepatitis. The aim of this study was to investigate the association of the most polymorphic HLA class II allele, human leukocyte antigen,DRB1, with the severity of hepatitis in male carriers of hepatitis B virus. In this prospective cohort study, a total of 204 carriers of hepatitis B virus (131 men and 73 women) who have been followed-up for more than 1 year at the outpatient clinic of a university hospital were collected consecutively. Fifty carriers of hepatitis B virus (group I) with alanine aminotransferase <2× upper limit of normal (mean follow-up 83.6 months) were compared with 154 chronic hepatitis B patients (group II) with alanine aminotransferase ,2× upper limit of normal (mean follow-up 81.3 months). Alleles of HLA-DRB1 were typed by the polymerase chain reaction,sequence specific oligonucleotide probe hybridization and genotypes of hepatitis B virus by melting curve analysis. HLA-DRB1*1101 was found in 18% of group I versus 8% of group II in male carriers (OR 0.23, P,=,0.020, after adjustment for age) and 4% versus 9.4% in female carriers (P,=,0.094). In male carriers harboring DRB1*1101, the distribution of hepatitis B viral genotype was comparable between the two groups. HLA-DRB1*1101 correlates with less severe hepatitis in Taiwanese male carriers of hepatitis B virus. J. Med. Virol. 81:588,593, 2009 © 2009 Wiley-Liss, Inc. [source] Diagnostic yield of oesophagogastroduodenoscopy in children with abdominal painALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 6 2009K. THAKKAR Summary Background, Abdominal pain is the most common indication for oesophagogastroduodenoscopy (OGD) in children. However, existing studies examining the diagnostic outcomes of OGD in children with abdominal pain are limited. Aim, To examine the diagnostic yield of OGD with biopsy in the evaluation of abdominal pain and to describe the endoscopic and histological findings in patients undergoing OGD for abdominal pain of unclear aetiology. Methods, We performed a retrospective cross-sectional cohort study in children under 18 years of age who had OGD for the primary indication of abdominal pain, at Texas Children's Hospital and Children's Hospital of The King's Daughters from 1 January 2002 to 30 June 2005. Results, Overall, OGD was diagnostic in 454 (38.1%) of the 1191 procedures, including reflux oesophagitis (23%, n = 271), Helicobacter pylori infections (5%, n = 55), peptic ulcers (3%, n = 32), eosinophilic oesophagitis (2%, n = 25), celiac disease (1%, n = 9) and Crohn's disease (0.5%, n = 7). Male gender, older age, elevated C-reactive protein and vomiting were associated with increased diagnostic yield. Conclusions, Our findings suggest that OGD is valuable for the evaluation of chronic abdominal pain in children, with a diagnostic yield of 38%. The majority of alarm symptoms and routine laboratory tests are not significantly associated with diagnostic yield. [source] Complete recovery of intestinal mucosa occurs very rarely in adult coeliac patients despite adherence to gluten-free dietALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 12 2009A. LANZINI Summary Background, Expected benefits of gluten-free diet (GFD) in coeliac patients include healing of small intestinal mucosa, but it remains unclear to what extent this benefit is achieved in adults. Aim, To assess factors affecting histological outcome of GFD in a large cohort of adult coeliac patients. Methods, We extracted information on 465 consecutive coeliac patients studied before and during GFD. Results, Duodenal biopsies at diagnosis were classified as Marsh I in 11, II in 25 and III in 429 cases. After a median 16 months GFD, 38 (8%) patients had histological ,normalization', 300 (65%) had ,remission' with persistent intraepithelial lymphocytosis, 121(26%) had ,no change' and 6 (1%) had ,deterioration'. Coeliac disease related serology was negative in 83% of patients with Marsh III lesion during GFD. Male gender and adherence to GFD were independently associated with histological ,normalization' and ,remission'. Persistence of intraepithelial lymphocytosis was not associated with human lymphocyte antigen gene dose or with Helicobacter pylori infection. Conclusions, Complete normalization of duodenal lesions is exceptionally rare in adult coeliac patients despite adherence to GFD, symptoms disappearance and negative CD related serology. Control biopsies are mandatory to identify lack of response to gluten-free diet. [source] Review article: medication non-adherence in ulcerative colitis , strategies to improve adherence with mesalazine and other maintenance therapiesALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 12 2008A. B. HAWTHORNE Summary Background, Significant number of patients with ulcerative colitis (UC) fail to comply with treatment. Aims, To review issues surrounding medication non-adherence in inflammatory bowel disease (IBD), including the clinical and health service implications in the UK, and discuss strategies for optimizing medication adherence. Methods, Articles cited were identified via a PubMed search, utilizing the words IBD, adherence, compliance, medication and UC. Results, Medication non-adherence is multifactorial involving factors other than dosing frequency. Male gender (OR: 2.06), new patient status (OR: 2.14), work and travel pressures (OR: 4.9) and shorter disease duration (OR: 2.1), among others are proven predictors of non-adherence in UC. These indicators can identify ,at-risk' patients and allow an individually tailored treatment approach to be introduced that optimizes medication adherence. A collaborative relationship between physician and patient is important; several strategies for improving adherence have been proven effective including open dialogue that takes into consideration the patient's health beliefs and concerns, providing educational (e.g. verbal/written information, self-management programmes) and behavioural interventions (e.g. calendar blister packs, cues/reminders). Conclusions, Educational and behavioural interventions tailored to individual patients can optimize medication adherence. Additional studies combining educational and behavioural interventions may provide further strategies for improving medication adherence rates in UC. [source] Do young hepatocellular carcinoma patients have worse prognosis?LIVER INTERNATIONAL, Issue 7 2006The paradox of age as a prognostic factor in the survival of hepatocellular carcinoma patients Abstract: Background/Aims: Our previous study showed that male hepatocellular carcinoma (HCC) patients below 40 years of age had the worst survival in the initial several years, but had the best prognosis thereafter. Thus, it seems that age has a paradoxical influence on the prognosis. To further clarify the issue of age on HCC prognosis, we initiated this study. Methods: A total of 11 312 HCC cases from seven medical centers from 1986 to 2002 were included. We analyzed the 1-year survival and survival after 1 year. Results: Male gender, age younger than 40 years old and hepatitis B virus (HBV) were associated with worse 1-year survival. In contrast, male gender, age younger than 40 years old and HBV were associated with better survival after 1 year. Higher percentage of the young HCC patients had a tumor size larger than 3 cm. 83.7% of HCC patients below 40 years of age were male and 89.8% of them were HBV carriers. Conclusions: If we encountered a young HCC patient, the patient will probably be a male HBV carrier. He would probably have larger tumor and is more likely to expire within 1 year than the older HCC patients. However, if the young HCC patient can survive for more than 1 year, he would probably have better survival in the following years than the older patients. [source] A risk-factor model of epistatic interaction, focusing on autismAMERICAN JOURNAL OF MEDICAL GENETICS, Issue 5 2002Marshall B. Jones Abstract Research to date on the genetics of autism has not uncovered a major susceptibility locus and indications are that a number of genes, perhaps as many as 15,20, may play detectable but minor roles in the etiology of the condition. To cope with this situation, a risk-factor model based on standard epidemiologic designs is proposed. The model supposes that adding a factor to a fixed set of existing factors always increases the total risk. Thus, according to the model genetic contributions cumulate but are not necessarily additive. A threshold, hence, epistasis is required. The model is applied to several conditions in which the risk of autism is elevated, some genetic (fragile X, tuberous sclerosis) and some exogenous (rubella and thalidomide embryopathies). Male gender is discussed as a risk factor. This approach is contrasted primarily with Gillberg and Coleman's view of autism as "a syndrome or series of syndromes caused by many different separate individual diseases." The principal point of difference is whether the effects of different causes cumulate or do not cumulate. In the present approach they do, in Gillberg and Coleman's they do not. © 2002 Wiley-Liss, Inc. [source] Chronic obstructive pulmonary disease in the absence of chronic bronchitis in ChinaRESPIROLOGY, Issue 7 2010Ming LU ABSTRACT Background and objective: COPD has a variable natural history and not all individuals follow the same course. The aim of this study was to assess the prevalence of COPD in the absence of chronic bronchitis (CB) based on a population survey in China, and to identify the determinants of CB in patients with COPD. Methods: A multi-stage cluster sampling strategy was used to survey a population from seven different provinces/cities of China. All residents over 40 years of age were interviewed using a standardized questionnaire and spirometry was measured. A post-bronchodilator FEV1/FVC < 70% was defined as the diagnostic criterion for COPD. All COPD patients who were screened were divided into two groups according to the presence or absence of CB. Results: Of the population of 20 245 that was surveyed, 70% of the 1668 patients who were diagnosed with COPD reported no history of CB. The ages, BMI and comorbidities of COPD patients with or without CB were similar. Male gender, residence in a rural area, having a lower level of education, exposure to tobacco smoke or biomass fuels, poor ventilation in the kitchen and a family history of respiratory disease were all associated with a higher risk of COPD with CB. Patients without CB had less difficulty in walking and higher FEV1/FVC values than patients with CB, but were more likely to be underdiagnosed. The strongest predictors of CB were male gender, current smoking and severity of dyspnoea. Conclusions: This survey confirmed that there is a high prevalence of COPD in the absence of CB in China. It appears that CB is not essential to the diagnosis of COPD. [source] Progression of Alphafetoprotein Before Liver Transplantation for Hepatocellular Carcinoma in Cirrhotic Patients: A Critical FactorAMERICAN JOURNAL OF TRANSPLANTATION, Issue 1 2010E. Vibert Liver transplantation (LT) for cirrhotic/Hepatocellular carcinoma (HCC) is associated with reduced survival in patients with poor histological features. Preoperative levels of alphafetoprotein (AFP) could predict negative biological features. AFP progression could be more relevant than static AFP levels in predicting LT outcomes. A total of 252 cirrhotic/HCC patients transplanted between 1985 and 2005 were reviewed. One hundred fifty-three patients were analyzed, 99 excluded (for nonsecreting tumors and/or salvage transplantation). Using receiver operating characteristics analysis for recurrence after LT, ,progression' of AFP was defined by >15 ,g/L per month before LT. A total of 127 (83%) were transplanted under and 26(16%) over this threshold. After 45 months of follow-up (median), 5-year overall survival (OS) and recurrence free-survival (RFS) were 72% and 69%, respectively. Five-year survival in the progression group was lower than the nonprogression group (OS 54% vs. 77%; RFS 47% vs. 74%). Multivariate analysis showed progression of AFP >15 ,g/L per month and preoperative nodules >3 were associated with decreased OS. Progression group and age >60 years were associated with decreased RFS. Male gender, progression of AFP and size of tumor >30 mm were associated with satellite nodules and/or vascular invasion. In conclusion, increasing AFP >15 ,g/L/month while waiting for LT is the most relevant preoperative prognostic factor for low OS/DFS. AFP progression could be a pathological preoperative marker of tumor aggressiveness. [source] Smoking is a major risk factor for wound dehiscence after midline abdominal incision; case,control studyANZ JOURNAL OF SURGERY, Issue 4 2009Saleh M. Abbas Abstract Background:, The incidence of acute fascial wound dehiscence (AFWD) after major abdominal operations is as high as 3%. AFWD is associated with mortality rates of 15,20%. Male gender, advanced age and numerous systemic factors including malignancy hypoproteinemia and steroid use have been associated with increased risk. The aim of the present study was to investigate the association between smoking prevalence and AFWD. Methods:, Middlemore Hospital records were retrieved from the 1997,2006 period for patients who had undergone midline abdominal surgery and developed AFWD. A return to the operating theatre for closure of the fascial dehiscence was required for study group inclusion. Each patient in the study group was matched to two control patients who had been admitted in the same year for surgery and who had a similar initial surgical intervention. Conditional logistic regression was used to calculate odds ratios with 95% confidence intervals, representing the risk of developing fascial wound dehiscence in smokers compared with the non-smoking group. Results:, There were 52 patients (32 male, 20 female) and 104 controls (64 male, 40 female). Median age for both groups was 63 years. A history of heavy tobacco use (,20 pack-years) was more prevalent in those who had AFWD (46%) compared with the control group (16%; P = 0.0002; odds ratio 3.7). Conclusions:, Smoking is associated with an increased incidence of acute fascial wound dehiscence following laparotomy. It is not known whether smoking is a causal or a surrogate factor. [source] The Elder Patient with Suspected Acute Coronary Syndromes in the Emergency DepartmentACADEMIC EMERGENCY MEDICINE, Issue 8 2007Jin H. Han MD ObjectivesTo describe the evaluation and outcomes of elder patients with suspected acute coronary syndromes (ACS) presenting to the emergency department (ED). MethodsThis was a post hoc analysis of the Internet Tracking Registry for Acute Coronary Syndromes (i,trACS) registry, which had 17,713 ED visits for suspected ACS. First visits from the United States with nonmissing patient demographics, 12-lead electrocardiogram results, and clinical history were included in the analysis. Those who used cocaine or amphetamines or left the ED against medical advice were excluded. Elder was defined as age 75 years or older. ACS was defined by 30-day revascularization, Diagnosis-related Group codes, or death within 30 days with positive cardiac biomarkers at index hospitalization. Multivariable logistic regression analyses were performed to determine the association between being elder and 1) 30-day all-cause mortality, 2) ACS, 3) diagnostic tests ordered, and 4) disposition. Multivariable logistic regression was also performed to determine which clinical variables were associated with ACS in elder and nonelder patients. ResultsA total of 10,126 patients with suspected ACS presenting to the ED were analyzed. For patients presenting to the ED, being elder was independently associated with ACS and all-cause 30-day mortality, with adjusted odds ratios of 1.8 (95% confidence interval [CI] = 1.5 to 2.2) and 2.6 (95% CI = 1.6 to 4.3), respectively. Elder patients were more likely to be admitted to the hospital (adjusted odds ratio, 2.2; 95% CI = 1.8 to 2.6), but there were no differences in the rates of cardiac catheterization and noninvasive stress cardiac imaging. Different clinical variables were associated with ACS in elder and nonelder patients. Chest pain as chief complaint, typical chest pain, and previous history of coronary artery disease were significantly associated with ACS in nonelder patients but were not associated with ACS in elder patients. Male gender and left arm pain were associated with ACS in both elder and nonelder patients. ConclusionsElder patients who present to the ED with suspected ACS represent a population at high risk for ACS and 30-day mortality. Elders are more likely to be admitted to the hospital, but despite an increased risk for adverse events, they have similar odds of receiving a diagnostic test, such as stress cardiac imaging or cardiac catheterization, compared with nonelder patients. Different clinical variables are associated with ACS, and clinical prediction rules utilizing presenting symptoms should consider the effect modification of age.

Objective The objective of this study was to evaluate the effects of prenatal cocaine exposure on special education at age 7 with adjustment for covariates. Methods As part of the prospective, longitudinal, multi-site study of children with prenatal cocaine exposure (Maternal Lifestyle Study), school records were reviewed for 943 children at 7 years to determine involvement in special education outcomes: (1) individualized education plan; (2) special education conditions; (3) support services; (4) special education classes; and (5) speech and language services. Logistic regression was used to examine the effect of prenatal cocaine exposure on these outcomes with environmental, maternal and infant medical variables as covariates, as well as with and without low child IQ. Results Complete data for each analysis model were available for 737,916 children. When controlling for covariates including low child IQ, prenatal cocaine exposure had a significant effect on individualized education plan. When low child IQ was not included in the model, prenatal cocaine exposure had a significant effect on support services. Male gender, low birthweight, white race and low child IQ also predicted individualized education plan. Low birthweight and low child IQ were significant in all models. White race was also significant in speech and language services. Other covariate effects were model specific. When included in the models, low child IQ accounted for more of the variance and changed the significance of other covariates. Conclusions Prenatal cocaine exposure increased the likelihood of receiving an individualized education plan and support services, with adjustment for covariates. Low birthweight and low child IQ increased the likelihood of all outcomes. The finding that white children were more likely to get an individualized education plan and speech and language services could indicate a greater advantage in getting educational resources for this population. [source] Exception from Informed Consent Enrollment in Emergency Medical Research: Attitudes and AwarenessACADEMIC EMERGENCY MEDICINE, Issue 2 2007Wayne Triner DO Objectives To explore attitudes surrounding exception from informed consent enrollment into research studies. In addition, the authors sought to determine the level of awareness of such an ongoing study among potential subjects, as defined by their presence in an emergency department (ED). Methods A convenience sample of urban academic ED patients and visitors was surveyed during a visit regarding their attitudes and awareness of an emergency exception from informed consent, blood-substitute trial ongoing in the community. Results There was a 13% refusal rate, and 32% of those approached had characteristics that met exclusion criteria. There were 497 surveys analyzed. There was a predominance of women, Caucasians, and persons with at least some college education. Only 39 (8%) of respondents reported awareness of the ongoing blood substitute trial, and only 19 (4%) were able to list a risk or benefit of participation. Education, income, and age were not associated with reported awareness. Male gender, younger age, awareness of the existing exception from informed consent study, and being married were associated with greater acceptability for such enrollment practices. Conclusions The overall awareness of an ongoing exception from informed consent trial after community consultation and notification was low. A population with potential for enrollment in such a study did not demonstrate a high degree of acceptance of such practices. There were differences among certain demographic groups in the degree of acceptance. These differences may guide institutional review boards and investigators in community-consultation strategies for future waiver of or exception from informed consent studies. [source] Name change among offender patients: an English high security hospital sampleCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 4 2002Birgit Völlm Clinical Research Fellow Background There is scant literature on change of name among psychiatric patients but a more substantial amount on the use of aliases among offenders. No one to our knowledge has explored name changes among offender patients. Aim This study was undertaken to establish the prevalence of name change among high security hospital patients and to compare those who changed name with those who did not. Hypothesis It was hypothesized that name change would be associated with male gender, repeated offending and a diagnosis of personality disorder. Method The clinical records of all patients resident in one high security hospital on 31 January 2000 were searched. As all such patients are compulsorily detained, all name changes must be recorded. Any change prior to that date was also noted, together with basic demographic and diagnostic information; supplementary data were obtained from the special hospitals' case register. Results Seventy-one patients (17%) of the resident population changed names (exclusive of a woman changing her surname on marriage). Name changing was associated with disrupted upbringing. Patients with personality disorder were more likely to change names than those with psychosis, regardless of sex, age or ethnic group. Those with psychosis were more likely to select unusual or symbolic names. Conclusions On the evidence of previous literature, people from this serious offender patient population were more likely to change names than other psychiatric patients but less likely than non-mentally-disordered offenders. Changes by people with psychosis seemed related to their illness, whereas changes by those with personality disorder might reflect childhood disruptions in rearing patterns.

Monfils Gustafsson Objective:, Preterm birth and restricted foetal growth are related to symptoms of psychiatric disorder. Our aim was therefore to investigate possible relations between being born preterm and/or small for gestational age (SGA) and later psychiatric hospitalization. Method:, A population-based registry study of psychiatric hospitalization of in total 155 994 boys and 148 281 girls born in Sweden in 1973,1975. Results:, The risk of hospitalization for all mental disorders was increased for preterm SGA boys (OR 2.19, 95% CI 1.49,3.21); at-term SGA boys (OR 1.55, 95% CI 1.34,1.79); at-term SGA girls (OR 1.31, 95% CI 1.15,1.50). At-term SGA boys and girls suffered increased risk of anxiety and adjustment disorders (OR 1.70, 95% CI 1.18,2.45 and OR 1.49, 95% CI 1.14,1.94). Preterm SGA boys were at risk of personality disorders (OR 3.30, 95% CI 1.16,9.41) and psychotic disorders (OR 4.36, 95% CI 1.85,10.30). Conclusion:, The results show a relationship between being born SGA and later psychiatric hospitalization, where preterm birth and male gender seem to increase the risk.

Prompers Abstract Aims To determine current management and to identify patient-related factors and barriers that influence management strategies in diabetic foot disease. Methods The Eurodiale Study is a prospective cohort study of 1232 consecutive individuals presenting with a new diabetic foot ulcer in 14 centres across Europe. We determined the use of management strategies: referral, use of offloading, vascular imaging and revascularization. Results Twenty-seven percent of the patients had been treated for > 3 months before referral to a foot clinic. This varied considerably between countries (6,55%). At study entry, 77% of the patients had no or inadequate offloading. During follow-up, casting was used in 35% (0,68%) of the plantar fore- or midfoot ulcers. Predictors of use of casting were male gender, large ulcer size and being employed. Vascular imaging was performed in 56% (14,86%) of patients with severe limb ischaemia; revascularization was performed in 43%. Predictors of use of vascular imaging were the presence of infection and ischaemic rest pain. Conclusion Treatment of many patients is not in line with current guidelines and there are large differences between countries and centres. Our data suggest that current guidelines are too general and that healthcare organizational barriers and personal beliefs result in underuse of recommended therapies. Action should be undertaken to overcome these barriers and to guarantee the delivery of optimal care for the many individuals with diabetic foot disease. [source] Myocardial perfusion imaging and cardiac events in a cohort of asymptomatic patients with diabetes living in southern FranceDIABETIC MEDICINE, Issue 4 2006A. Sultan Abstract Aims, To assess the association between abnormal stress myocardial perfusion imaging (MPI) and cardiac events (CE) in asymptomatic patients with diabetes and with , 1 additional risk factor. Predictors of abnormal stress MPI were also evaluated. Methods, Four hundred and forty-seven consecutive patients who underwent stress MPI were prospectively followed for 2.1 [0.5,4.1] years for the subsequent occurrence of hard CE (myocardial infarction and sudden or coronary death) and soft CE (unstable angina and ischaemic heart failure requiring hospitalization). Re-vascularization procedures performed as a result of the screening protocol were not included in the analysis. Results, Follow-up was successful in 419 of 447 patients (94%), of whom 71 had abnormal MPI at baseline. Medical therapy was intensified in all subjects and especially in those with abnormal MPI. Twenty-three patients with abnormal MPI underwent a re-vascularization procedure. CEs occurred in 14 patients, including six of 71 patients (8.5%) with abnormal MPI and eight of 348 patients (2.3%) with normal MPI (P < 0.005). Only two patients developed a hard CE and 12 a soft CE. In multivariate analysis, abnormal MPI was the strongest predictor for CEs [odds ratio (OR) (95% CI) = 5.6 (1.7,18.5)]. Low-density lipoprotein cholesterol , 3.35 mmol/l [OR (95% CI) = 7.3; 1.5,34.7] and age > median [OR (95% CI) = 6.0 (1.2,28.6)] were additional independent predictors for CE. The independent predictors for abnormal MPI were male gender, plasma triglycerides , 1.70 mmol/l, creatinine clearance < 60 ml/min and HbA1c > 8%, with male gender the strongest [OR (95% CI) = 4.0 (1.8,8.8)]. Conclusions, Asymptomatic patients with diabetes in this study had a very low hard cardiac event rate over an intermediate period. This could be explained by the effects of intervention or by the low event rate in the background population. Randomized studies of cardiac heart disease screening are required in asymptomatic subjects with diabetes to determine the effectiveness of this intervention. Diabet. Med. (2006) [source] The association of coronary calcium score and conventional cardiovascular risk factors in Type 2 diabetic subjects asymptomatic for coronary heart disease (The PREDICT Study)DIABETIC MEDICINE, Issue 10 2004R. S. Elkeles Abstract Aim To determine the association between coronary calcification score (CACS) obtained by electron beam computed tomography (EBCT) and cardiovascular risk factors in Type 2 diabetic subjects entered into a prospective cohort study. Methods Type 2 diabetic subjects attending routine hospital diabetic clinics without known coronary heart disease (CHD) underwent EBCT to measure CACS. Demographic data were obtained and conventional cardiovascular risk factors were measured at baseline. Results Four hundred and ninety-five subjects were assessed of whom 67.7% were male. They had a mean (sd) age of 62.9 (7.1) years, with median (inter-quartile range) duration of diabetes of 8 (4,13) years. None had a history of coronary artery disease. Forty-five per cent were receiving lipid-lowering agents (including 36% statins). In a univariate analysis, there were significant associations between increased CACS and age, duration of diabetes, male gender, waist,hip ratio (WHR), systolic blood pressure, and the use of statins. In a multivariate model adjusting for the possible interaction of these and other factors, the significant association between CACS and WHR, systolic blood pressure, male gender and statin use remained. Conclusions The close association between CACS and WHR and the association with systolic blood pressure suggest that coronary calcification may be particularly linked to the metabolic syndrome in Type 2 diabetes. [source] Vigabatrin and Epilepsy: Lessons LearnedEPILEPSIA, Issue 7 2007John M. Wild Summary:,Purpose: The risk factors for visual field loss attributable to vigabatrin (VAVFL) are equivocal. This multinational, prospective, observational study aimed to clarify the principal/major factors for VAVFL. Methods: Interim analysis of three groups with refractory partial epilepsy, stratified by age (8,12 years; >12 years) and exposure to vigabatrin (VGB). Group I comprised participants treated with VGB for ,6 months, Group II participants previously treated with VGB for ,6 months who had discontinued the drug for ,6 months and Group III those never treated with VGB. Perimetry was undertaken at least every six months, for up to 36 months; results were evaluated masked to drug exposure. Results: Based upon 563 participants in the locked data set, 432 yielded one or more Conclusive visual field examinations. For Group I, the frequency of VAVFL at the last Conclusive examination was 10/32 (31.2%) for those aged 8,12 years and 52/125 (41.6%) for those aged >12 years. For Group II, the proportions were 4/39 (10.3%) and 31/129 (24.0%). No cases resembling VAVFL manifested in Group III. VAVFL was associated with duration of VGB therapy (Odds ratio [OR] 14.2; 95% CI 5.0 to 40.5); mean dose of VGB (OR 8.5; 95% CI 2.2 to 33.2); and male gender (OR 2.1; 95% CI 1.2 to 3.7). VAVFL was more common with static than kinetic perimetry (OR 2.3, 95% CI 1.3 to 4.2). Conclusions: The therapeutic benefit of VGB is counteracted by the progressive accrual of the risk of VAVFL with continued exposure and with increase in mean dose. [source] The cigar as a drug delivery device: youth use of bluntsADDICTION, Issue 10 2003Stephen Soldz ABSTRACT Aims, Blunts are hollowed-out cigars used to smoke marijuana (and perhaps other substances) in the United States. We investigated rates of blunt use; whether cigar use reported in surveys may actually be blunt use; the relationship of blunt to cigar use; characteristics of blunt users; brands of cigars used to make blunts; and drugs added to blunts. Design, A school-based survey of youth, the Cigar Use Reasons Evaluation (CURE). Setting, Eleven schools across Massachusetts. Participants, A total of 5016 students in grades 7,12. Measurements, CURE items assessing blunt, cigar and cigarette use, brands used to make blunts, drugs added to blunts and demographics were used. Findings, Life-time blunt use was reported by 20.0% of the sample, with use greater among high school (25.6%) than middle school (11.4%) students, and among males (23.7%) than females (16.6%). Self-reported cigar use rates were not influenced strongly by blunt use being misreported as cigar use. In a multivariate model, blunt use was associated with male gender, higher grade in school, lower GPA, truancy, lower school attachment, not living in a two-parent family, being of ,other' race/ethnicity and current use of both cigarettes and cigars. ,Phillies' was the most popular brand of cigar for making blunts, used by 59.$% of users. ,Garcia y Vega' (18.0%) was the second most popular. Twenty-eight per cent of blunt users had added drugs other than marijuana to blunts. Conclusions, The use of blunts as a drug delivery device is a serious problem. Efforts to address it will require the cooperation of the tobacco control and substance abuse prevention systems. [source] Probabilities of alcohol high-risk drinking, abuse or dependence estimated on grounds of tobacco smoking and nicotine dependenceADDICTION, Issue 6 2003Ulrich John ABSTRACT Aims, To estimate probabilities of alcohol high-risk drinking, alcohol abuse and alcohol dependence on grounds of smoking-behaviour related variables and single nicotine dependence criteria. Design, Cross-sectional population-based study. Setting, Adult population of a region in north Germany. Participants, Cigarette smokers (n = 2437) among a random sample of 4075 females and males aged 18,64, drawn in 1996. Measurement, Smoking, nicotine dependence according to the Diagnostic and Statistical Manual of Psychiatric Disorders (DSM-IV) and the Fagerström Test for Nicotine Dependence (FTND); increasing alcohol-related harm (ARH): high-risk drinking, DSM-IV alcohol abuse, remitted and current alcohol dependence diagnosed by the Composite International Diagnostic Interview (CIDI). Findings, Having smoked 30 cigarettes or more per day, onset of smoking at the age of 17 or younger, nicotine dependence and single nicotine dependence criteria revealed odds ratios higher than 4.0 for alcohol dependence. For alcohol dependence, a logistic regression model showed an increased odds ratios for male gender, smoking for 25 years or more, no attempt to quit or cut down, continuation of smoking despite problems, craving for nicotine, withdrawal experience 1 day or longer, smoking first cigarette in the morning 5 minutes or less after waking. The probability of increasing ARH was more likely in males, smokers for 25 years or more, no attempt to quit or cut down, continuation of smoking despite problems and smoking first cigarette in the morning 5 minutes or less after waking. Conclusions, Gender and single nicotine dependence criteria show particularly high probabilities of alcohol dependence and increasing ARH. Interventions need to take these connections into account. [source] School-aged children after the end of successful treatment of non-central nervous system cancer: longitudinal assessment of health-related quality of life, anxiety and copingEUROPEAN JOURNAL OF CANCER CARE, Issue 4 2009H. MAURICE-STAM phd The aim of the study was to investigate: (1) health-related quality of life (HRQoL) and anxiety in school-aged cancer survivors during the first 4 years of continuous remission after the end of treatment; and (2) correlations of disease-related coping with HRQoL and anxiety. A total of 76 survivors aged 8,15 years completed questionnaires about HRQoL, anxiety and disease-related cognitive coping at one to five measurement occasions. Their HRQoL was compared with norm data, 2 months (n = 49) and 1 year (n = 41), 2 years (n = 41), 3 years (n = 42) and 4 years (n = 27) after treatment. Through longitudinal mixed models analyses it was investigated to what extent disease-related cognitive coping was associated with HRQoL and anxiety over time, independent of the impact of demographic and medical variables. Survivors reported worse Motor Functioning (HRQoL) 2 months after the end of treatment, but from 1 year after treatment they did no longer differ from the norm population. Lower levels of anxiety were associated with male gender, being more optimistic about the further course of the disease (predictive control) and less searching for information about the disease (interpretative control). Stronger reliance on the physician (vicarious control) was associated with better mental HRQoL. As a group, survivors regained good HRQoL from 1 year after treatment. Monitoring and screening survivors are necessary to be able to trace the survivors at risk of worse HRQoL. [source] | ||||||||||||||||||||||||||||||||||||||||
