BackgroundSchizophrenia is linked with early medical comorbidity and mortality. These observations indicate possible “accelerated biological aging” in schizophrenia, although prior findings are mixed, and few such studies have examined the role of gender. One putative marker of biological aging is leukocyte telomere length (LTL), which typically shortens with age.MethodsWe assessed LTL in phenotypically well characterized 134 individuals with schizophrenia (60 women and 74 men) and 123 healthy comparison subjects (HCs) (66 women and 57 men), aged 26 to 65 years.ResultsOverall, LTL was inversely associated with age (t(249) = -6.2, p < 0.001), and a gender effect on the rate of LTL decrease with age was found (t(249) = 2.20, p = 0.029), with men declining more rapidly than women. No significant overall effect of diagnosis on the rate of decline was detected. However, at the average sample age (48 years), there was a significant gender effect in both schizophrenia and HC groups (t(249) = 2.48, p = 0.014), with women having longer LTL than men, and a significant gender X diagnosis effect (t(249) = 2.43, p = 0.016) - at the average sample age, women with schizophrenia had shorter LTL than HC women.DiscussionGender, not the diagnosis of schizophrenia, was the major factor involved with LTL shortening across the age range studied. We discuss the constraints of a cross-sectional design and other methodological issues, and indicate future directions. Understanding the impact of schizophrenia on biological aging will require separate evaluations in men and women. 相似文献

Peculiar word use in schizophrenia has been emphasized by many authors, however the definition or the linguistic and clinical correlates of this phenomenon are not clear. We propose a new, standard and reliable method to extract a numerical measure of peculiar word use with operationalized definitions. We applied a modified version of the Controlled Word Association Test (Turkish version) to a pool of healthy subjects (N=55) and used the data as norm to compare the degree of peculiarity and patterns of word association among patients with schizophrenia (N=33), their healthy siblings (N=31) and healthy controls (N=32). We also explored the relationship of peculiar word use with patterns of word association (semantic versus phonologic) and formal thought disorder. Patients and their siblings performed worse on measures of verbal fluency. They also generated more peculiar words and relied less on semantic associations, compared to healthy controls. Peculiar word use was associated with the severity of formal thought disorder and the tendency to make use of phonologic associations in the patient group and their siblings, whereas neither of the word association patterns predicted peculiar word use in the control group. Our results provide empirical support to previous observations about the peculiarity of schizophrenic speech. Peculiar word use could be associated with a deficit to employ semantic classifications in verbal fluency tasks and thus relying more on sound-based associations. Excess use of phonologic associations may be playing a mediating role between semantic processing abnormalities and formal thought disorder. 相似文献

PURPOSE: This study was conducted to evaluate the effect of age, age-related changes in renal function, and gender on the single-dose pharmacokinetics of orally administered gabapentin (GBP). METHODS: The pharmacokinetics of a single 400-mg oral dose of GBP were studied in 36 healthy subjects (18 men and 18 women) aged 20-78 years. Serial blood samples and total urine output were collected for 48 h after the dose. GBP concentrations in plasma and urine were measured by high-performance liquid chromatography, and pharmacokinetic parameters were calculated by noncompartmental methods. RESULTS: All subjects tolerated the drug well, with only mild symptoms reported. No change in maximal GBP plasma concentration (Cmax), time at which Cmax occurred (tmax), or apparent volume of distribution (V/F) with age was noted. A significant linear decline in apparent oral clearance (CL/F), elimination-rate constant (lambda z), and renal clearance (CLR) with increasing age was observed (p < 0.005). Because total urinary recovery of unchanged drug (an estimate of F for GBP) did not change with age, the decline in CL/F and lambda z can be explained by the decline in CLR. The only pharmacokinetic parameter that was significantly different between genders was Cmax, which was approximately 25% higher for women than for men (p = 0.016), consistent with gender differences in body size. CONCLUSIONS: The results of this study suggest that changes in renal function are responsible for age-related changes in GBP pharmacokinetics. Reduction of GBP dosage may be required in elderly patients with reduced renal function. The pharmacokinetics of GBP are similar in men and women. 相似文献

We have evaluated the potential influence of ABO-blood group, gender and age, on laboratory procedures used for detection of Activated Protein C Resistance (APCR), using over 300 normal donor samples and two distinct laboratory test procedures, one based on an Activated Partial Thromboplastin Time (APTT) and the other on a Russell Viper Venom Time (RVVT). We observed a statistically significant influence of ABO-blood group on APTT test times, both in the presence and absence of Activated Protein C (APC), which was no longer evident when using assay ratios. This ABO effect was not observed using the RVVT-based assay procedure. We also observed a gender effect on the APTT-based procedure, such that females (compared to males) provided shorter APTT test times (both with and without APC). This effect was still evident when using APTT assay ratios, but was again not observed using the RVVT-based procedure. We also observed an age related increase in APTT ratios. Interestingly, some previous studies have reported some specific gender and age related effects on APTT-based testing, but reports using RVVT-based testing are lacking, as are ABO related studies. Such findings should be considered as potential variables when associating specific laboratory based findings of APCR to clinical thrombophilia conditions. 相似文献

The early conceptualizations of schizophrenia have noted some sex/gender differences in epidemiology and clinical expression of the disorder. Over the past few decades, the interest in differences between male and female patients has expanded to encompass brain morphology and neurocognitive function. Despite some variability and methodological shortcomings, a few patterns emerge from the available literature. Most studies of gross neuroanatomy show more enlarged ventricles and smaller frontal lobes in men than in women with schizophrenia; finding reflecting normal sexual dimorphism. In comparison, studies of brain asymmetry and specific corticolimbic structures, suggest a disturbance in normal sexual dimorphism. The neurocognitive findings are somewhat consistent with this picture. Studies of cognitive functions mediated by the lateral frontal network tend to show sex differences in patients which are in the same direction as those observed in the general population, whereas studies of processes mediated by the corticolimbic system more frequently reveal reversal of normal sexual dimorphisms. These trends are faint and future research would need to delineate neurocognitive differences between men and women with various subtypes of schizophrenia (e.g., early versus late onset), while taking into consideration hormonal status and gender of tested participants. 相似文献

Objective
The objective was to assess the presence of different subgroups, via age-at-onset (AAO) analysis, in a schizophrenia population consecutively recruited through an Early Psychosis Service in London, Canada.Method
Admixture analysis was applied in order to identify a model of separate normal distribution of AAO characterized by different means, variances and population proportions to allow for evaluation of different subgroups in a sample of 187 unrelated patients with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnosis of schizophrenia.Results
The best-fitting model suggested three subgroups with means and standard deviations of 16.8±1.9, 22.3±2.1 and 32.7±5.9 years comprising 41%, 30% and 29% of the schizophrenia sample, respectively. These three subgroups were categorized as early, intermediate and late onset with cutoffs determined by admixture analysis to be 19 and 26 years of age, respectively. In our investigation, the definition of early-onset schizophrenia is the main outcome. We considered the clinical variables mainly related to the heritability and neurobiology of schizophrenia. Single status was strongly associated with early onset (P< .001). The male gender (P= .023), as well as a history of drug abuse (P= .004), was significantly associated with early onset. Interestingly, lower academic achievement was also associated with early-onset schizophrenia (P< .001).Conclusion
Overall, our study showed that a typical early-onset schizophrenia patient is more likely to be a single male, with a history of drug abuse and birth complications, and lower academic achievement as compared to the late-onset subgroup. 相似文献14.

ObjectivePrevious studies have shown that age, gender, and body mass index (BMI) affect amplitude of sensory nerve action potentials (SNAP), but the total effects of multiple factors or the most prominently affected nerves have not been elucidated. This study systematically investigated effects of these factors.MethodsAmplitude of SNAP of the median, ulnar, superficial radial, superficial peroneal, and sural nerves was measured in 105 healthy subjects. The effects of age, gender, and BMI on each nerve were estimated by multivariate linear regression analysis.ResultsSNAP amplitude decreased with age in all five nerves. Women had greater SNAP amplitude than men in the upper limb nerves (median, ulnar, and radial), but not in the lower limb nerves (peroneal and sural). Similarly, greater BMI was associated with smaller amplitudes in the upper limb nerves, but not in the lower limb nerves. Multivariate analyses showed the three factors explained 50% of the variation in the median nerve, 46% in the ulnar nerve, and 22–32% in the remaining nerves.ConclusionsThe effects of age, gender, and BMI on SNAP amplitudes are not identical in different sensory nerves. Age was strongly correlated with SNAP amplitude in the nerves tested, whereas gender and BMI affect amplitudes only in the upper limb nerves.SignificanceAge, gender, and BMI should be taken into account in clinical practice, but the extent of influence depends on the sensory nerves examined. 相似文献

Socio-demographic and clinical predictors of quality of life in patients with schizophrenia or schizo-affective disorder 总被引:1,自引:0,他引:1
This article discusses the relationships between socio-demographic, clinical characteristics and Quality of Life (QOL) of individuals with schizophrenia. The client version of the Canadian version of the Wisconsin Quality of Life Index (CaW-QLI) was used with a population of 182 individuals with either schizophrenia or schizo-affective disorder. Multivariate analyses of variance with Tukey post hoc tests were used to assess differences between groups defined according to socio-demographic and clinical characteristics on all sub-scale scores in addition to the global score on the CaW-QLI. Relationships between socio-demographic characteristics and QOL were found for gender, age, education, employment status and living arrangement. Differences in QOL were found between groups with different clinical characteristics, such as diagnosis, hospitalization during the last 12 months and age at first hospitalization. Using socio-demographic and clinical variables in addition to psychosocial variables appears to be promising for understanding QOL in psychotic patients. Methodological considerations for future research are discussed. 相似文献

The relationship between lateral ventricular size or its asymmetry and age at the onset of schizophrenia was investigated in 20 schizophrenic patients diagnosed according to DSM-III-R criteria. The ventriclebrain ratio (VBR) was determined using three transaxial slices of magnetic resonance image (MRI) and asymmetry of the lateral ventricle was evaluated from the laterality index of the lateral ventricular area: (left-right/lef+right)×100. Each age at the onset of the prodromal and active phase according to DSM-III-R criteria was determined for each patient. The results showed that asymmetry of the ventricle, but not VBR, was significantly correlated inversely with age at the onset of both the prodromal phase and active phase. Neither asymmetry nor VBR correlated with the duration of illness, age at MRI scanning, or severity of clinical symptoms. It would thus appear that greater asymmetry of the ventricle is associated with earlier onset of schizophrenia. 相似文献

Deep brain stimulation (DBS) is an established treatment for essential tremor (ET). The nucleus ventralis intermedius thalami (Vim) is the target of choice, but promising results have been presented regarding DBS in the posterior subthalamic area (PSA). The aim of this study was to evaluate the possible influence of gender, age and severity of disease on the outcome of these procedures.Sixty eight patients (34 Vim, 34 PSA) with ET were included in this non-randomised study. Evaluation using the Essential Tremor Rating Scale (ETRS) was performed before, and one year after surgery concerning PSA DBS, and at a mean of 28 ± 24 months concerning Vim DBS. Items 5/6 and 11–14 (hand tremor and hand function) were selected for analysis of tremor outcome.The efficacy of DBS on essential tremor was not related to age or gender. Nor was it associated with the severity of tremor when the percentual reduction of tremor on stimulation was taken into account. However, patients with a more severe tremor at baseline had a higher degree of residual tremor on stimulation. Tremor in the treated hand and hand function were improved with 70% in the Vim group and 89% in the PSA group. 相似文献

Objective
Schizophrenia affects men more than women, but this may not be true at all ages. This study examines the incidence of first hospitalization for treatment of schizophrenia in each sex over different ages.Methods
We compared the incidence of first admission for treatment in a cohort of 46,388 males and 43,680 females followed from birth until ages 29-41, using life tables and proportional hazards methods.Results
Life table estimates of cumulative incidence by age 40 were 1.44% in males and 0.86% in females. For over all ages the relative risk (RR) in males was 1.6 (95% confidence limits = 1.4-1.8) compared with females. Before age 17 there was no significant difference between the sexes (RR = 0.86, 0.56-1.3). Excess risk in males was observed only from age 17 (RR = 1.7, 1.4-1.9). There was no evidence of the incidence in females catching up with that in males, during the 30s.Conclusion
In this population, there was a significant change, over age, in the relative incidence of first hospitalization for schizophrenia between the sexes; the excess incidence in males first developed at age 17. 相似文献20.
In this study, we clarified the gender and age-related asymmetries of the central sulcus (CS) in early adulthood using a parametric ribbon method. The CS was reconstructed and parameterized automatically from 3D MR images of 112 healthy right-handed subjects. The 3D anatomic morphology of the CS was presented using 5 sulcal parameters, including sulcal depth position-based profile (DPP), average depth (AD), average width (AW), top length (TL) and bottom length (BL). Asymmetry differences in DPPs were found in the medial and lateral part of the CS. In addition, significant gender differences were observed in the medial and middle parts of the right CS DPPs but scattered in the left side. We found leftward asymmetries of TL in males, but rightward asymmetries of AW in females. Males had a greater AW than females in the right hemisphere. Moreover, the females had bilateral longer TL and a longer left BL than did males. We also found significant age-related reductions in bilateral TL and increases in bilateral AW, with males presenting more obvious age-related change than females. There were sexual differences of the CS patterns, in which Type b was the most dominant sulcal pattern in males, whereas Type a was dominant in females. Three-way ANOVA revealed sexual and asymmetry changes of TL and BL among different CS patterns. Our findings indicate that the lateralization performances of the CS manifest as sexually and regionally different. In addition, it is suggested that males may undergo a faster progress of aging compared to females. 相似文献
