Objective: To investigate the association between some fertile life characteristics and Parkinson disease (PD) in women. Methods: Women affected by PD and control subjects were matched one to one by age (±2 years). One hundred thirty-one women with idiopathic PD and 131 matched control subjects were interviewed. Controls were randomly selected from the resident list of the same municipality of residence of cases. All subjects had a Mini-Mental State Examination score of ≥24. Cumulative length of pregnancies, age at menarche, age and type of menopause, and estrogen use before and after menopause were investigated in cases and controls through a structured questionnaire. Models of matched pair univariate analysis and conditional logistic regression analyses were used to calculate adjusted odds ratio (OR), 95% CI, and two-tailed p values for the investigated variables. Results: PD was significantly associated with a fertile life length shorter than 36 years (OR 2.07; 95% CI 1.00 to 4.30) and a cumulative length of pregnancies longer than 30 months (OR 2.19; 95% CI 1.22 to 3.91). An inverse association between PD and surgical menopause (adjusted OR 0.30; 95% CI 0.13 to 0.77) was also found. Conclusions: An association between factors reducing estrogen stimulation during life and PD was found. These results support the hypothesis that endogenous estrogens play a role in the development of PD.
The growing incidence of neurodegenerative disorders in our populations is leading the research to identify potential biomarkers and targets for facilitating their early management and treatments. Biomarkers represent the crucial indicators of both physiological and pathological processes. Specific changes in molecular and cellular mechanisms of physiological processes result in biochemical alterations at systemic level, which can give us comprehensive information regarding the nature of any disease. In addition, any disease biomarker should be specific and reliable, able to consent of distinguishing the physiological condition of a tissue, organ, or system from disease, and be diverse among the various diseases, or subgroups or phenotypes of them. Accordingly, biomarkers can predict chances for diseases, facilitate their early diagnosis, and set guidelines for the development of new therapies for treating diseases and disease-making process. Here, we focus our attention on brain neurotrophic factor (BDNF)–tropomyosin receptor kinase (Trk) pathway, describing its multiple roles in the maintenance of central nervous system (CNS) health, as well as its implication in the pathogenesis of multiple sclerosis (MS). In addition, we also evidence the features of such pathway, which make of it a potential MS biomarker and therapeutic target.
Background: Frequency and associated risk factors for hemorrhagic transformation (HT), a worrying complication of ischemic stroke (IS), are not clearly defined. Our aim was to estimate the overall frequency and risk factors for HT in a hospital-based population. Methods: A retrospective review of medical records of patients discharged from our department during the period 2004–2006 with a diagnosis of anterior IS. Demographic, clinical and hematological information was collected. Uni- and multivariate logistic regression analyses were used to estimate risk for spontaneous HT. Results: We included 240 patients (125 males, 52%), mean age at admission was 72.5 years. HT was observed in 29 patients (12%). At univariate analysis, consciousness impairment at admission (OR 5.6, 95% CI 1.3–28.2), the presence of early CT signs (OR 2.4, 95% CI 1.1–5.3), infarcts of medium-large size (OR 11.3, 95% CI 4.1–30.8), cardioembolic stroke (OR 2.3, 95% CI 1.1–5.2) and low total cholesterol levels (OR 3.3, 95% CI 1.3–8.2) were significantly associated with HT. At multivariate analysis, only infarct size (OR 10.2, 95% CI 3.2–32.1) was still significantly associated with HT. Conclusions: Frequency of HT in our study was 12%. Consistently with previous results, HT was associated with the size of ischemic area. As patients included in our study did not receive thrombolytic therapy, our results are applicable to those patients whom clinicians, working in a hospital setting, usually deal with.
Because of the limited information on cervical spondylotic radiculopathy, we conducted a door-to-door two-phase survey in a Sicilian municipality. We first screened for cervical spondylotic radiculopathy among the inhabitants of the municipality: (N = 7653, as of the prevalence day, November 1, 1987). Study neurologists then investigated those subjects suspected to have had a cervical spondylotic radiculopathy. Diagnoses were bases on specified criteria. We found 27 subjects affected by CSR (17 definite, 10 possible). Prevalence (cases per 1000 population) was 3.5 in the total population; it increased to a peak at age 50-59 years, and decreased thereafter. The age-specific prevalence was consistently higher in women. Comparison with other prevalence studies shows similar age-specific patterns, but different magnitudes, which may partly reflect methodologic differences across studies.
