Comprehensive studies of cognitive impairment of the elderly with type 2 diabetes

GERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 3 2006
Takashi Sakurai
Type 2 diabetes mellitus is associated with cognitive dysfunction and increases the risk of dementia for the elderly. The aim of the study presented here was to provide a brief review of how disturbance of glucose and metabolic homeostasis may be implicated in the cognitive decline of patients with type 2 diabetes. Several risk factors such as nutrition, cerebrovascular disorders and the neurotoxic effects of hyperglycemia may combine for the formation of mechanisms of cognitive decline in the diabetic elderly. It should be noted that cognitive deficits of diabetes are accompanied by neuroradiological changes in the brain, so that cognitive dysfunction both with and without brain structural changes may overlap during cognitive decline of the diabetic elderly. Recently, we conducted two studies to explore, by means of brain imaging, hierarchical relationships among clinical profiles of diabetes, cognitive function, white matter hyperintensity and brain atrophy. The results suggested that subcortical brain atrophy and hyperintensity constitute predictors of the rate of progression of cognitive dysfunction in the diabetic elderly, while cortical atrophy is associated with high diastolic blood pressure and lower HbA1c. These hypotheses may explain in part the underlying mechanisms of cognitive impairment in the diabetic elderly. Prospective intervention studies are needed, however, to clarify the mechanism of cognitive dysfunction of the diabetic elderly and what the targets are for preventive measures. [source]


Dietary intake in sensitized children with recurrent wheeze and healthy controls: a nested case,control study

ALLERGY, Issue 4 2006
C. S. Murray
Background:, The rising prevalence of asthma and allergic disease remains unexplained. Several risk factors have been implicated including diet, in particular poly-unsaturated fats and antioxidant intake. Methods:, A nested case,control study comparing the dietary intake of sensitized children with recurrent wheeze (age 3,5 years) and nonsensitized children who had never wheezed was carried out within an unselected population-based cohort. Cases and controls were matched for age, sex, parental atopy, indoor allergen exposure and pet ownership. Dietary intake was assessed using a validated semi-quantitative food frequency questionnaire and nutrient analysis program. Results:, Thirty-seven case,control pairs (23 male, mean age 4.4 years) participated. Daily total polyunsaturated fat intake was significantly higher in sensitized wheezers (g/day, geometric mean, 95% confidence intervals: 7.1, 6.4,7.9) compared with nonsensitized nonwheezy children (5.6, 5.0,6.3, P = 0.003). Daily omega-3 and omega-6 fat intakes were not significantly different between the two groups. No significant differences were found in intake of any antioxidant or antioxidant cofactors between the groups. Conclusions:, Young sensitized wheezy children had a significantly higher total polyunsaturated fat intake compared with nonsensitized nonwheezy children. However, we were unable to distinguish a significant difference in specific poly-unsaturated fat intakes. Otherwise the children in both groups had a very similar nutritional intake. [source]


Clinicopathologic characteristics and prognostic factors in 420 metastatic breast cancer patients with central nervous system metastasis

CANCER, Issue 12 2007
Kadri Altundag MD
Abstract BACKGROUND. Breast cancer is the second most common cause of central nervous system (CNS) metastases. Several risk factors for CNS metastases have been reported. The objective of the current study was to describe clinicopathologic characteristics and prognostic factors in breast cancer patients with CNS metastases. METHODS. The authors retrospectively evaluated clinical data from 420 patients who had been diagnosed with breast cancer and CNS metastasis between 1994 and 2004 at the University of Texas M. D. Anderson Cancer Center. RESULTS. The median age of the patients at the time of diagnosis of breast cancer was 45 years (range, 25,77 years). Premenopausal and postmenopausal patients were distributed equally. Most patients had invasive ductal histology (91.2%), grade 3 tumors (81.4%) (using the modified Black nuclear grading system), T2 tumor classification (40.1%), and N1 lymph node status (59.7%) diagnosis. Forty percent of patients had estrogen receptor (ER)-positive disease, and 34% had progesterone receptor-positive disease. HER-2/neu status was recorded for only 248 patients, and 39% of the patients in that group had HER-2/neu -positive disease. The most common sites of first metastasis were liver, bone, and lung. CNS metastasis was the site of first recurrence in 53 patients (12%). In total, 329 patients had received either neoadjuvant treatment (113 patients) or adjuvant chemotherapy (216 patients). The majority of those patients (74.4%) had received anthracycline-based regimens. Metastasis was solitary in 111 patients (26.4%), and 29 patients had only leptomeningeal metastases. The median time from breast cancer diagnosis to CNS metastasis was 30.9 months (range, from ,5 months to 216.7 months). The median follow-up after a diagnosis of CNS metastasis was 6 months (range, 7,95.9 months). In all, 359 patients died, and the overall median survival was 6.8 months. Only age at diagnosis and ER status were associated significantly with overall survival in the multivariate analysis. CONCLUSIONS. The current results indicated that the prognosis remains patients with breast cancer metastatic to the CNS. More effective treatment approaches are needed for patients with CNS metastases, even for those with favorable prognostic factors, such as ER-positive tumors or younger age.

Polymorphism of matrix metalloproteinase genes (MMP1 and MMP3) in patients with varicose veins

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 5 2009
M. Kurzawski
Summary Background., Several risk factors for varicose veins have been identified: female gender, combined with obesity and pregnancy, occupations requiring standing for long periods, sedentary lifestyle, history of deep-vein thrombosis and family history. However, no specific gene variants related to a wide prevalence of varicosities in general population have been identified. Extracellular matrix composition, predominantly maintained by matrix metalloproteinases (MMPs), may affect the vein-wall structure, which may lead to dilation of vessels and cause varicosities. Aims., MMP-1 (tissue collagenase I) and MMP-3 (stromelysin I) expression was found to be raised in varicose veins compared with normal vessels. Therefore, a study was conducted to evaluate a potential association between MMP1 and MMP3 promoter polymorphisms and a risk of varicose veins. Methods., Genotyping for the presence of the polymorphisms ,1607dupG (rs1799750) in MMP1 and ,1171dupA (rs3025058) in the MMP3 promoter region was performed using PCR and restriction-fragment length polymorphism assays in a group of 109 patients diagnosed with varicose veins and 112 healthy controls. Results., The frequencies of the MMP1 and MMP3 alleles (minor allele frequency 0.440 in patients vs. 0.451 in the controls for MMP1,1607*G and 0.514 vs. 0.469 for MMP3,1171*dupA, respectively) and of genotypes did not differ significantly between patients and controls. Conclusions., The MMP1,1607dupG and MMP3,1171dupA promoter polymorphisms are not valuable markers of susceptibility for varicose veins. [source]


Translational Mini-Review Series on Immunology of Vascular Disease: Accelerated atherosclerosis in vasculitis

CLINICAL & EXPERIMENTAL IMMUNOLOGY, Issue 3 2009
J. W. Cohen Tervaert
Premature atherosclerosis has been observed during the course of different systemic inflammatory diseases such as rheumatoid arthritis and sytemic lupus erythematosus. Remarkably, relatively few studies have been published on the occurrence of accelerated atherosclerosis in patients with vasculitis. In giant cell arteritis (GCA), mortality because of ischaemic heart disease is not increased. In addition, intima media thickness (IMT) is lower in patients with GCA than in age-matched controls. In contrast, IMT is increased significantly in Takayasu arteritis, another form of large vessel vasculitis occurring in younger patients. In Takayasu arteritis and in Kawasaki disease, a form of medium-sized vessel vasculitis, accelerated atherosclerosis has been well documented. In small vessel vasculitis because of anti-neutrophil cytoplasmic autoantibodies-associated vasculitis, cardiovascular diseases are a major cause of mortality. IMT measurements reveal conflicting results. During active disease these patients experience acceleration of the atherosclerotic process. However, when inflammation is controlled, these patients have atherosclerotic development as in healthy subjects. Several risk factors, such as diabetes and hypertension, are present more often in patients with vasculitis compared with healthy controls. In addition, steroids may be pro-atherogenic. Most importantly, many patients have impaired renal function, persistent proteinuria and increased levels of C-reactive protein, well-known risk factors for acceleration of atherosclerosis. Enhanced oxidation processes, persistently activated T cells and reduced numbers of regulatory T cells are among the many pathophysiological factors that play a role during acceleration of atherogenesis. Finally, autoantibodies that may be relevant for acceleration of atherosclerosis are found frequently in elevated titres in patients with vasculitis. Because patients have an increased risk for cardiovascular events, vasculitis should be treated with as much care as possible. In addition, treatment should be considered with angiotensin-converting-enzyme inhibitors and/or angiotensin receptor-1 blockers, statins and acetylsalicyl acid. Finally, classical risk factors for cardiovascular disease should be monitored and treated as much as possible. [source]


Genetic variants in the IMPA2 gene do not confer increased risk of febrile seizures in Caucasian patients

EUROPEAN JOURNAL OF NEUROLOGY, Issue 4 2007
M. A. Blair
Pathogenesis of febrile seizures (FS), causing the most common of types of seizures in children, remains unknown. Genetic factors appear to play a pivotal role and FS can be inherited as a monogenic or genetically complex disorder. Several risks factors have been proposed but many of the previously reported genetic associations were not replicated. Non-coding polymorphisms in the myo-inositol monophosphatase 2 gene (IMPA2) have been suggested as a susceptibility factor for FS in Japanese patients. It is unknown whether genetic variants in the same gene constitute a risk factor for FS in other ethnic groups because the frequency of FS is significantly higher in Japanese children than in Caucasian patients. We investigated the role of the IMPA2 gene in a cohort of 96 unrelated Caucasian subjects with a history of FS. We did not identify any significant differences in genotypes of cases and matched controls; no mutations or non-synonymous polymorphisms were detected in these individuals. Our data suggest that the genetic variants in the IMPA2 gene are not associated with a risk of FS in Caucasian patients and patients from various genetic groups are likely to have different genetic causes of FS.

From Migraine To Chronic Daily Headache: The Biological Basis of Headache Transformation

HEADACHE, Issue 8 2007
Ian D. Meng PhD
Migraine headache carries the potential of transforming into chronic daily headache (CDH) over a period of time. Although several risk factors for migraine progression to CDH have been identified, the biological basis of this transformation is unknown. In this review, the consequences of stressful life events and medication overuse, 2 risk factors associated with the development of CDH, on brain processes involved in headache are examined. The extensive overlap in both neural circuitry and cellular events that occur with stress, medication overuse, and migraine provide insight into potential mechanisms that may lead to CDH. Particular attention is devoted to the effect of stress and medication overuse on peripheral and central neuroimmune interactions that can facilitate pain signaling. These interactions include the degranulation of mast cells in the dura, causing the sensitization of primary afferent neurons, as well as the activation of glial cells in the brain that can lead to central sensitization. It is hypothesized that the biological processes involved in migraine headache are directly impacted by stress, medication overuse, and other risk factors, resulting in a reduced threshold for induction of headache and transformation of episodic migraine to CDH.

Nonalcoholic fatty liver disease: is all the fat bad?

INTERNAL MEDICINE JOURNAL, Issue 4 2004
A. D. Clouston
Abstract Nonalcoholic fatty liver disease is now a major cause of liver disease in developed countries, largely as a result of an epidemic of obesity, diabetes and sedentary lifestyles. This has resulted in raised clinical awareness and diagnostic refinement. The entity encompasses several histologic patterns from benign steatosis to nonalcoholic steatohepatitis, the latter having a significant risk of progressive fibrosis and the development of cirrhosis. Labor­atory tests and imaging are not able to distinguish steatosis from steatohepatitis, which requires liver biopsy. However following an assessment of several risk factors, patients can be stratified for the potential risk of fibrosis, allowing the rational use of liver biopsy. This review will describe the various patterns of nonalcoholic fatty liver disease and relate this to disease pathogenesis and progression. Strategies for management, including experimental interventions, will be discussed. (Intern Med J 2004; 34: 187,191) [source]


Risk factors for testicular cancer , differences between pure non-seminoma and mixed seminoma/non-seminoma?

INTERNATIONAL JOURNAL OF ANDROLOGY, Issue 4 2006
E. L. Aschim
Summary The origin of testicular germ cell cancer (TGCC) is believed to be carcinoma in situ cells developed in utero. Clinically, TGCCs are divided into two major histological groups, seminomas and non-seminomas, where the latter group includes non-seminomatous TGCCs with seminomatous components (mixed S/NS TGCC). Recent studies, however, have suggested that non-seminomas and mixed S/NS TGCCs could have certain differences in aetiology, and in this study the TGCCs were divided into three, rather than the conventional two histological groups. A large case-control study was undertaken on data on all live-born boys registered in the Medical Birth Registry of Norway during the period 1967,1998 (n = 961 396). Among these were 1087 TGCC cases registered in the Cancer Registry of Norway until February 2004. We found several risk factors for TGCC, including low parity, low gestational age, epilepsy and retained placenta. Several of the variables studied seemed to be risk factors for specific histological groups, e.g. parity 0 vs. 2 and low gestational age being associated with increased risk of non-seminomas, but not of mixed S/NS TGCC, and low maternal age being associated with increased risk of mixed S/NS TGCC, but not of non-seminomatous TGCC. Therefore, our results might suggest that non-seminomas and mixed S/NS TGCCs have partially different risk factors, whose associations may be obscured by combining these two histological groups. The histological groups were not significantly different, however. Most of our findings on risk factors for TGCC are in agreement with at least some previous studies. An unexplainable exception is low birth weight being associated with reduced risk of TGCC in our study. [source]


The association of plasma androgen levels with breast, ovarian and endometrial cancer risk factors among postmenopausal women

INTERNATIONAL JOURNAL OF CANCER, Issue 1 2010
Kim N. Danforth
Abstract Although androgens may play an etiologic role in breast, ovarian and endometrial cancers, little is known about factors that influence circulating androgen levels. We conducted a cross-sectional analysis among 646 postmenopausal women in the Nurses' Health Study to examine associations between adult risk factors for cancer, including the Rosner/Colditz breast cancer risk score, and plasma levels of testosterone, free testosterone, androstenedione, dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEAS). All analyses were adjusted for age, laboratory batch and other cancer risk factors. Free testosterone levels were 79% higher among women with a body mass index of ,30 vs. <22 kg/m2 (p -trend <0.01) and 25% higher among women with a waist circumference of >89 vs. ,74 cm (p -trend = 0.02). Consuming >30 g of alcohol a day vs. none was associated with a 31% increase in DHEA and 59% increase in DHEAS levels (p -trend = 0.01 and <0.01, respectively). Smokers of ,25 cigarettes per day had 35% higher androstenedione and 44% higher testosterone levels than never smokers (p -value, F -test = 0.03 and 0.01, respectively). No significant associations were observed for height or time since menopause with any androgen. Testosterone and free testosterone levels were ,30% lower among women with a hysterectomy vs. without (both p -values < 0.01). Overall breast cancer risk was not associated with any of the androgens. Thus, several risk factors, including body size, alcohol intake, smoking and hysterectomy, were related to androgen levels among postmenopausal women, while others, including height and time since menopause, were not. Future studies are needed to clarify further which lifestyle factors modulate androgen levels. [source]


Risk for breast cancer among women with endometriosis

INTERNATIONAL JOURNAL OF CANCER, Issue 6 2007
Lisbeth Bertelsen
Abstract Although several risk factors are common to endometriosis and breast cancer, the results of observational studies of an association have so far been inconsistent. We evaluated the relationship between endometriosis and breast cancer on the basis of data on selected cancers and medical histories from the Danish nationwide cancer and hospital registries used in a large case,cohort study. A total of 114,327 women were included in the study of whom 1,978 women had received a diagnosis of endometriosis and 16,983 had had a diagnosis of breast cancer between 1978 and 1998. Of the women with endometriosis, 236 subsequently received a diagnosis of breast cancer. The crude overall rate ratio for breast cancer after endometriosis was 1.00 and after adjustment for reproductive factors, calendar-period, bilateral oophorectomy and benign breast disease, the rate ratio was 0.97 (95% confidence interval, 0.85,1.11). The risk for breast cancer increased with age at diagnosis of endometriosis, so that women in whom endometriosis was diagnosed at a young age (approximately <40 years) had a reduced risk for breast cancer and women in whom endometriosis was diagnosed at older ages (approximately ,40 years) tended to have an increased risk for breast cancer. The reduced risks observed among young women may reflect their exposure to drugs with antiestrogenic effects. The increased risk associated with endometriosis among postmenopausal women may be due to common risk factors between postmenopausal endometriosis and breast cancer or an altered endogenous estrogen. © 2006 Wiley-Liss, Inc.

Cancer risk perceptions in an urban Mediterranean population

INTERNATIONAL JOURNAL OF CANCER, Issue 1 2005
Montse García
Abstract The objective of our study was to analyze the perceived (belief) or adopted (behavior) measures to reduce cancer risk in a Spanish population. We used cross-sectional data from the Cornella Health Interview Survey Follow-up Study (CHIS.FU). We analyzed 1,438 subjects who in 2002 answered questions about risk perceptions on cancer and related behavior (668 males and 770 females). The benefits of avoiding cigarette smoking (95.8%), sunlight exposure (94.9%) and alcohol (81.0%) were widely recognized. On the other hand, electromagnetic fields (92.1%), food coloring and other food additives (78.4%) or pesticides (69.4%), whose role in cancer occurrence, if any, remain unproven, were clearly considered as cancer risk factors in this population. Compared to men, women more frequently reported healthy behaviors, and the role of exogenous factors (i.e., environmental risk factors) were widely popular. There was a socioeconomic gradient on cancer risk perception with respect to several lifestyle or dietary factors. Individuals with higher educational level scored lower in several risk factors than those with primary or less than primary school education. Smokers reported adopting fewer healthy behaviors than former or never smokers. How people perceive health issues and risk or make choices about their own behavior does not always follow a predictable or rational pattern. © 2005 Wiley-Liss, Inc. [source]


Erectile dysfunction in hemodialysis patients with diabetes mellitus: Association with age and hemoglobin A1c levels

INTERNATIONAL JOURNAL OF UROLOGY, Issue 7 2004
YASUYOSHI MIYATA
Abstract Aim:, Erectile dysfunction (ED) is common in patients with diabetes mellitus (DM) as well as those undergoing hemodialysis (HD). The purpose of this study is to investigate the frequency and severity of ED in HD patients with DM and those without DM. In addition, we examined the relationship between erectile function and several risk factors, including presence of DM and hemoglobin A1c levels in HD patients. Methods:, This study involved 180 patients on HD, including 66 HD patients with DM (DM-HD) and 114 patients without DM (non-DM-HD). We evaluated erectile function using an abridged five-item version of the international index of erectile function (IIEF-5). Logistic regression analysis was used to investigate the relationship between presence of ED and several risk factors. Results:, The total score of IIEF-5 in DM-HD patients (9.5 ± 4.2) was significantly lower than in non-DM-HD patients (13.5 ± 5.7). The prevalence of severe ED was 42.4% and 18.4% in DM-HD patients and non-DM-HD patients, respectively. Age, cardiovascular disease history, and DM were identified as independent risk factors for the presence of ED. Furthermore, age and elevated hemoglobin A1c levels were identified as independent risk factors for the presence of severe ED. Conclusion:, DM-HD patients are more likely to have ED, and particularly severe forms of ED, than non-DM-HD patients. DM and elevated hemoglobin A1c levels were associated with the presence of ED or severe ED, respectively. Aging was identified as an independent factor in both ED and severe ED. [source]


Suicidality among Finnish anaesthesiologists

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 8 2009
P. M. LINDFORS
Background: Suicide rates among physicians have constantly been reported to be higher than in the general population and anaesthesiologists appear to lead the suicide statistics among physicians. Methods: A cross-sectional questionnaire study was sent to all working Finnish anaesthesiologists (n=550) investigating their suicidality (ideation and/or planning and/or attempt). The response rate was 60%. Results: One in four had at some time seriously been thinking about suicide. Respondents with poor health (crude odds ratios 11.2 and 95% confidence interval 3.8,33.0), low social support (10.5, 4.0,27.9), and family problems (6.5, 3.4,12.5) had the highest risk of suicidality. The highest risks at work were conflicts with co-workers (4.1, 2.3,7.1) and superiors (2.1, 1.2,3.6), on-call-related stress symptoms (3.9, 1.9,8.3) and low organizational justice (1.9, 1.1,3.2). If a respondent had several risk factors, the risk of suicidality doubled with each cumulating factor. Conclusions: The reported level of suicidal ideation among Finnish anaesthesiologists is worth concern. It should be of utmost importance to screen the risk factors and recognize suicidal physicians in order to help them. Interpersonal relationships, decision-making procedures, and on-call-burden should be focused on when aiming to prevent suicidality among physicians. [source]


Hepatic artery thrombosis after orthotopic liver transplantation: A review of nonsurgical causes

LIVER TRANSPLANTATION, Issue 2 2001
Sabrina Pastacaldi
Hepatic artery thrombosis (HAT) is one of the principal causes of morbidity and graft loss following liver transplantation. There are several risk factors for the development of HAT; technical aspects of the arterial anastomosis are important particularly for early thrombosis, but the improvement of surgical technique has lessened this problem. Apart from technical causes, other risk factors include a variety of conditions such as low donor/recipient age ratio, immunologic factors, clotting abnormalities, tobacco use, and infections. In particular, cytomegalovirus (CMV) infection of endothelial cells has been recently suggested as an infective cause of HAT, as it is known to be followed by a rapid procoagulant response. Thus, latent CMV in an allograft may become activated and promote or contribute to vascular thrombosis. This review evaluates these aspects, focusing on data relating CMV infection or viremia to HAT following liver transplantation. [source]


Low back pain in individuals with chronic airflow limitation and their partners , A preliminary prevalence study

PHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 4 2002
Anneliese Synnot
Abstract Background and Purpose The prevalence of low back pain in individuals with chronic airflow limitation, and their partners, is unknown. Individuals with chronic airflow limitation, and their respective partners, are likely to have several risk factors that may increase the predisposition for low back pain. The aim of the present study was to provide preliminary data on the prevalence of low back pain in individuals with chronic airflow limitation, and their partners. Method A cross-sectional observational study design was used. Individuals with chronic airflow limitation, and their partners, were approached at South Australian metropolitan Lung Support Group meetings and invited to participate in the study. Three commonly used questionnaires: the Medical Outcomes Survey Short-Form 36 (MOS SF-36); the St George's Respiratory Questionnaire (SGRQ); and the Nordic Low Back Pain Questionnaire (NLBPQ) were used to collect data on general health, respiratory health and low back pain prevalence, respectively. Odds ratios and independent Student's t -tests were used to analyse data by use of Epi Info Version 6.0 software. Results Sixty subjects participated in the study: 41 individuals with chronic airflow limitation and 19 partners of individuals with chronic airflow limitation. The lifetime, 12-month and seven-day prevalence of low back pain in individuals with chronic airflow limitation was 69%, 58% and 31%, respectively. The prevalence of low back pain in the partners of individuals with chronic airflow limitation was found to be higher, at 74%, 68% and 58 %, respectively. Four significant relationships between general and respiratory health, and low back pain were demonstrated for individuals with chronic airflow limitation. Conclusions The prevalence of low back pain in individuals with chronic airflow limitation was comparable to the lifetime prevalence for the general and older population, and greater than the 12-month prevalence reported for the older population. The prevalence of low back pain for the partners of individuals with chronic airflow limitation was consistently higher than the lifetime and 12-month prevalence reported for individuals with chronic airflow limitation, the older population and family care workers. These findings suggest a larger prevalence study of low back pain in individuals with chronic airflow limitation, and their partners, is warranted. Copyright © 2002 Whurr Publishers Ltd. [source]


Improved Erectile Function after Cardiac Resynchronization Therapy in a Patient with Heart Failure,A Case Report

THE JOURNAL OF SEXUAL MEDICINE, Issue 10 2009
Damian Domanski MD
ABSTRACT Introduction., Erectile dysfunction (ED) is very common among heart failure patients and has a very dramatic, negative impact on patients' quality of life. Both ED and heart failure have several risk factors in common; however, little data exist on the correlation between the heart failure-targeted interventions and improvement of ED. Aim., To report a case of improved sexual function after cardiac resynchronization. Methods., We report the case of a 63-year-old man with ischemic cardiomyopathy and long-standing ED, who experienced significant improvement of his sexual function following biventricular pacing device implantation. Notably, earlier interventions attempting to improve his ED, namely, heart failure medication adjustments and phosphodiesterase-5 inhibitors, have failed. Results., Following cardiac resynchronization therapy, patient's erectile function improved without any other ED-specific treatment. Conclusions., To the best of our knowledge, this is the first report of improved sexual function in a patient with heart failure and ED following cardiac resynchronization therapy. Although the exact mechanisms remain unknown, we believe that cardiac resynchronization improves ED through improved cardiac and endothelial function. Domanski D, Rosanio S, and Schwarz ER.

Risk Factors for Erectile Dysfunction in Patients with Urethral Strictures Secondary to Blunt Trauma

THE JOURNAL OF SEXUAL MEDICINE, Issue 11 2008
Chao Feng PhD
ABSTRACT Introduction., Erectile dysfunction (ED) is a well-known consequence of pelvic fracture, particularly in cases involving urethral injury. There are several risk factors that may be related to ED. However, no systemic approach is used to assess erectile function secondary to urethral trauma. Aim., To investigate ED associated with urethral injury secondary to pelvic fracture and perineal trauma. Methods., Forty patients with traumatic urethral strictures secondary to blunt traumatic impact episode to the pelvis or perineum were included in our study. Pelvic fractures and urethral strictures were categorized according to injury types and radiological findings. All patients underwent nocturnal penile tumescence (NPT) monitoring, dynamic color-duplex Doppler ultrasonography (D-CDDU) before surgery. NPT monitoring was conducted again after surgery. Main Outcome Measures., The events of NPT and D-CDDU were recorded. Results., In all patients, 11 had organic ED demonstrated by NPT. Vascular pathology was identified in three of 11 patients (27%). The peak systolic velocity of cavernosal artery was lower in patients with pubic diastasis in comparison to those without diastasis (P < 0.05). Significant changes in penile length and circumference were noted in posterior urethral injury compared with anterior urethral injury during erection (P < 0.05). The erectile duration time has a similar statistical difference in two groups mentioned above. However, no significant difference could be observed in the end-to-end anatomosis procedure before and after surgery (P > 0.05). Conclusions., The pelvic fracture type, especially pubic diastasis, is a risk factor for ED following urethral injury. Location of the stricture is also a risk factor for subsequent erectile dysfunction. Feng C, Xu Y-M, Yu J-J, Fei X-F, and Chen L.

Inflammatory processes of prostate tissue microenvironment drive rat prostate carcinogenesis: Preventive effects of celecoxib

THE PROSTATE, Issue 2 2009
Narayanan K. Narayanan
Abstract BACKGROUND Prostate tissue microenvironment is susceptible to several risk factors including carcinogens, dietary factors, hormones, cytokines and growth factors that could induce chronic inflammation. Because of the difference in the serum levels and the intrinsic ability of monocytes/macrophages to cause harm, the transcriptional responses triggered by inflammatory stimuli must be controlled. Unfortunately, an in-depth association between prostate cancer and potential mediators of inflammation has not been completely investigated. METHODS To determine whether activated macrophage (infiltrating monocytes), iNOS and NF-,B are primary mediators of inflammation, besides COX-2, in prostate carcinogenesis, we examined tissue sections of rat prostate tumor induced by N -methyl- N -nitrosourea (MNU) plus testosterone in a follow-up study. We performed H&E and immunohsitochemical staining of the prostate tissue to detect specific markers of inflammation. RESULTS We report an increase in infiltrating monocyte, iNOS, NF-,Bp65, VEGF and TNF-, at the early and advanced stages of tumor growth in MNU plus testosterone treated rats. Monocyte infiltration was often found in the stromal and perivascular regions of the DL prostate. We conclude for the first time that prostate cancer induced by MNU plus testosterone partly involves mediators of inflammation which could trigger the process of carcinogenesis and cause loss of apoptosis. Selective COX-2 inhibitor celecoxib at a dose of 500 mg/kg/bw administered for 52 weeks reduced infiltrating monocytes, inhibited iNOS, NF-,B p65 expression, induced apoptosis and tumor growth inhibition. CONCLUSION Carcinogen plus testosterone induced prostate carcinogenesis showing activation of macrophage, iNOS and NF-,Bp65 could be prevented by celecoxib or related anti-inflammatory agents.

Risk factors for ectopic pregnancy: A case-control study

AUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 6 2006
Abdullah KARAER
Abstract Aim:, To identify the risk factors for ectopic pregnancy. Methods:, We conducted a prospective case-control study for the role of several risk factors in the occurrence of ectopic pregnancy in Turkey. A total of 225 cases and 375 controls were compared for sociodemographic characteristics, cigarette smoking, obstetric, gynaecological, surgical histories, the presence or absence of assisted conception and contraceptive usage. Results:, The main risk factors for ectopic pregnancy were prior ectopic pregnancy (adjusted odds ratio (AOR): 13.1) and a history of infectious reproductive system (AOR for pelvic inflammatory disease: 6.8). Other risk factors found to be associated with an increased risk for ectopic pregnancy were multisexual partner (AOR: 3.5), history of infertility (AOR: 2.5), induced conception cycle (AOR: 3.4), current intrauterine device usage (AOR: 3.2), prior Caesarean section (AOR: 2.1) and cigarette smoking at the time of conception (AOR = 1.7). On the contrary, barrier methods were protective from ectopic pregnancy (AOR: 0.4). Conclusions:, The increased awareness and knowledge of risk factors have enabled an early and accurate diagnosis of ectopic pregnancy. This study has found prior pelvic infection to be a major aetiological factor for ectopic pregnancy. Furthermore, other factors found to be associated with ectopic pregnancy, such as prior ectopic pregnancy, infertility history and induced conception cycle, may be the result of a previous pelvic infection that may cause tubal sequelae. These factors are potential targets for intervention and modification. [source]


Attrition in longitudinal studies: who do you lose?

AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 4 2006

Objective: To describe the risk factors for various types of attrition in three age cohorts of women in a longitudinal study and to discuss strategies to minimise attrition. Methods: Analysis of survey data from the Australian Longitudinal Study on Women's Health, collected by mailed questionnaire. In 1996, the study recruited and surveyed a national random sample of ,younger' (18,23 years, n=14,247), ,mid-age' (45,50 years, n=13,716), and ,older' women (70,75 years, n=12,432), and began a staggered cycle of mailed follow-up questionnaires: 1998 (mid-age), 1999 (older), 2000 (younger) and so on. Demographic, health and social risk factors for attrition were examined using multivariate analysis. Results: Attrition at survey 2 was highest among younger women (32%), mainly because of participants not being contactable (21%), and lower among the older (16%) and mid-age women (10%). At survey 1, the survey 2 non-respondents were more likely to report having less education, being born in a non-English-speaking country and being a current smoker, in all cohorts, and had poorer health (mid-age and older cohort) and more diffculty managing on their income (younger and mid-age). Conclusion: Although the magnitude of different types of attrition was found to differ by age, there were several risk factors for attrition that remained consistent. These fndings are important to inform future studies on ways to lessen or prevent systematic loss of participants. Implications: Recruitment and follow-up methods in longitudinal studies should be tailored to maximise retention of participants at higher risk of dropout. [source]


Evaluation of early stimulation programs for enhancing brain development

Abstract The term ,early intervention' designates educational and neuroprotection strategies aimed at enhancing brain development. Early educational strategies seek to take advantage of cerebral plasticity. Neuroprotection, a term initially used to characterize substances capable of preventing cell death, now encompasses all interventions that promote normal development and prevent disabilities, including organisational, therapeutic and environment-modifying measures, such as early stimulation programs. Early stimulation programs were first devised in the United States for vulnerable children in low-income families; positive effects were recorded regarding school failure rates and social problems. Programs have also been implemented in several countries for premature infants and low-birth-weight infants, who are at high risk for neurodevelopmental abnormalities. The programs target the child, the parents or both. The best evaluated programs are the NIDCAP (Newborn Individualized Developmental Care and Assessment Program) in Sweden for babies <1500 g in neonatal intensive care units and the longitudinal multisite program IHDP (Infant Health and Development Program) created in the United States for infants <37 weeks or <2500 g. Conclusion: Although the NIDCAP and the IHDP targeted different populations, they produced similar effects in several regards: efficacy was greatest with programs involving both the parents and the child; long-term stimulation improved cognitive outcomes and child,parent interactions; cognition showed greater improvements than motor skills and larger benefits were obtained in families that combined several risk factors including low education attainment by the mothers.

Well-being among children and adolescents with mobility impairment in relation to demographic data and disability characteristics

Abstract Aim: To describe the well-being of children and adolescents with mobility impairment in relation to demographic data and disability characteristics. Methods: The present study is based on interviews with 141 subjects aged 7 to 18 y with impaired mobility. Perceived overall well-being was measured by a nine-grade visual scale, the Snoopy scale. Independence or dependence was evaluated by the Index of Independence in Activities of Daily Living. Motor capacity was assessed with an instrument including active movements, rapidity, locomotion and balance as well as the presence and localization of pain. Results: Since there were no significant differences in well-being regarding the diagnostic-related group, additional disorder/disability or the degree of disability, the impairment per se did not necessarily influence well-being negatively. Even though the majority of the children and adolescents in the study indicated a high level of well-being, several risk factors for a lower level of well-being were identified: greater age, not living with both parents, being a first-generation immigrant, having an acquired disease/injury and experience of pain. Conclusion: These findings increase our limited knowledge of well-being among children/adolescents with mobility impairment and provide a basis for effective care and future research. [source]


Mental health of children and adolescents in 12 European countries,results from the European KIDSCREEN study

Within the European Screening for and Promotion of Health-Related Quality of Life in Children and Adolescents,A European Public Health Perspective (KIDSCREEN) Study, emotional well-being and behaviour was examined in national representative samples of 22,000 children and adolescents aged 8 to 18. The proportion of children and adolescents showing signs of mental health problems (Strengths and Difficulties Questionnaire,SDQ) varied across countries and socio-demographic and socio-economic subgroups. Risk factors examined included adverse family climate, low socio-economic status, poor social support and decreased mental well-being of the parents. When several risk factors occur simultaneously, the prevalence of mental health problems increases markedly. Children and adolescents with mental health problems display distinctly impaired health-related quality of life (KIDSCREEN-10). Cross-cultural differences in the observed patterns of mental health problems were discussed. High-risk groups are cross-culturally characterized by poor social support and mental distress of parents. Strengthening social and familial resources should be a key objective, both in prevention and in interventions.,Copyright © 2008 John Wiley & Sons, Ltd. [source]
