Background Although depression is known to be frequent in Parkinson's disease (PD), it is unclear how mood can change and/or impact on patient's quality of life (QoL) over time. Our aim was to analyze the frequency of depression, mood related factors and the contribution of mood to a patient's QoL perception in regard to disease duration. Methods PD patients recruited from the COPPADIS cohort from January 2016 to November 2017 were included in this cross-sectional study. Three groups were defined: = 10 years (Group C). Analysis with well-planned linear regression models was conducted to determine how different factors contribute to mood (Beck Depression Inventory-II [BDI-II] as dependent variable), to health-related QoL (39-item Parkinson's Disease Questionnaire [PDQ-39SI] as dependent variable) and to global QoL (European Health Interview Survey - Quality of Life Eight-Item Index [EUROHIS-QOL8] as dependent variable). Results Six hundred and sixty-three PD patients (62.6 +/- 8.9 years old, 59.6% males) were included: Group A, 50.1% (n = 332); Group B, 33.3% (n = 221) and Group C, 16.6% (n = 110). There were no differences between the three groups in terms of the frequency of depressive symptoms nor the frequency of depression type (major vs. minor vs. subthreshold) (p = 0.729). However, the unique percent variance of PDQ-39SI and EUROHIS-QOL8 explained by BDI-II total score was 2 (23.7%) and threefold (26.9%), respectively, in Group C compared to the other two groups. EUROHIS-QOL8 total score provided the highest unique contribution to mood (16.8%). Conclusions Although depression-type frequency does not appear to change over time in PD; the contribution of mood on QoL perception is greater in patients with longer disease duration.

Over the past century, evidence has emerged that endocrine disrupting chemicals (EDCs) have an impact on reproductive health. An increased frequency of reproductive disorders has been observed worldwide in both wildlife and humans that is correlated with accidental exposures to EDCs and their increased production. Epidemiological and experimental studies have highlighted the consequences of early exposures and the existence of key windows of sensitivity during development. Such early in life exposures can have an immediate impact on gonadal and reproductive tract development, as well as on long-term reproductive health in both males and females. Traditionally, EDCs were thought to exert their effects by modifying the endocrine pathways controlling reproduction. Advances in knowledge of the mechanisms regulating sex determination, differentiation and gonadal development in fish and rodents have led to a better understanding of the molecular mechanisms underlying the effects of early exposure to EDCs on reproduction. In this manuscript, we review the key developmental stages sensitive to EDCs and the state of knowledge on the mechanisms by which model EDCs affect these processes, based on the roadmap of gonad development specific to fish and mammals., The authors are grateful to the Intersectoral Centre for Endocrine Disruptor Analysis (ICEDA)'s researcher network that facilitated this Special Issue.

[Objective] To identify factors related to a poor health-related and global quality of life (QoL) in a cohort of non-demented Parkinson's disease (PD) patients and compare to a control group., [Methods] The data correspond to the baseline evaluation of the COPPADIS-2015 Study, an observational, 5-year follow-up, multicenter, evaluation study. Three instruments were used to assess QoL: (1) the 39-item Parkinson's disease Questionnaire (PDQ-39), (2) a subjective rating of global QoL (PQ-10), and (3) the EUROHIS-QOL 8-item index (EUROHIS-QOL8). Multiple linear regression methods were used to evaluate the direct impact of different variables on these QoL measures., [Results] QoL was worse in PD patients (n = 692; 62.6 ± 8.9 years old, 60.3% males) than controls (n = 206; 61 ± 8.3 years old, 49.5% males): PDQ-39, 17.1 ± 13.5 vs 4.4 ± 6.3 (p, [Conclusions] QoL is worse in PD patients than in controls. Mood, non-motor symptoms burden, and gait problems seem to be the most relevant factors affecting health-related and global perceived QoL in non-demented PD patients.

To assess the impact of a long-term initiative to improve safety culture among professionals working in a Health Area, and to know their perceived usefulness.An uncontrolled intervention study was designed in a public health care organization including a 3rd level hospital and 5,000 professionals. To measure the impact, the AHRQ Survey was conducted by telephone. A total of 7 dimensions of culture were measured, before starting the project (2012, n=100) and 3 years later (2015, n=207). Variations between 2012 and the respondents aware of the project in 2015 (RAP) were compared, as also between this last group and the rest of respondents (RNAP). The utility was assessed using a 5-item Likert scale, defining higher utility by medians 4 or higher.The response rates were above 80%. In 2015, the 41.5% of respondents were RAP (95%CI: 34.8-48.3), which was perceived as of high utility. Negative variations were detected in "sense of security" (-9.9%, P.01, vs. 2012, and -4.2% between 2015 groups) and "feedback and communication errors" (-10.0% vs. 2012, and -8.9% between 2015 groups, P.05). There was a not-significant positive variation in "openness in communication" (1.3% vs. 2012, and 6.9% between 2015 groups). The "management support" showed a not-significant improve in 2015 (37.0%, 95%CI: 30.9-43.1, in RAP; and 38.3%, 95%CI: 33.1-43.4, in RANP) in comparison to 2012 (31.4%, 95%CI: 28.4-39.7).A paradoxical worsening is detected in several dimensions, this probably due to immaturity of the organization and the instrument used. Thus, tools explicitly considering the degree of maturity may be more appropriate to measure cultural changes, although more studies are needed.

Background We investigated the association between heart rate and its variability with the parameters that assess vascular, renal and cardiac target organ damage. Methods A cross-sectional study was performed including a consecutive sample of 360 hypertensive patients without heart rate lowering drugs (aged 56 ± 11 years, 64.2% male). Heart rate (HR) and its standard deviation (HRV) in clinical and 24-hour ambulatory monitoring were evaluated. Renal damage was assessed by glomerular filtration rate and albumin/creatinine ratio; vascular damage by carotid intima-media thickness and ankle/brachial index; and cardiac damage by the Cornell voltage-duration product and left ventricular mass index. Results There was a positive correlation between ambulatory, but not clinical, heart rate and its standard deviation with glomerular filtration rate, and a negative correlation with carotid intima-media thickness, and night/day ratio of systolic and diastolic blood pressure. There was no correlation with albumin/creatinine ratio, ankle/brachial index, Cornell voltage-duration product or left ventricular mass index. In the multiple linear regression analysis, after adjusting for age, the association of glomerular filtration rate and intima-media thickness with ambulatory heart rate and its standard deviation was lost. According to the logistic regression analysis, the predictors of any target organ damage were age (OR = 1.034 and 1.033) and night/day systolic blood pressure ratio (OR = 1.425 and 1.512). Neither 24 HR nor 24 HRV reached statistical significance. Conclusions High ambulatory heart rate and its variability, but not clinical HR, are associated with decreased carotid intima-media thickness and a higher glomerular filtration rate, although this is lost after adjusting for age.

To analyze the reliability and validity of a semiautomated tool for assessing retinal vessel caliber and to describe the relationship of measures taken to cardiovascular risk and target organ damage.A total of 210 patients aged 34-75 years were selected with retinography. Retinal photographs were digitized, and superior and inferior temporal vessels were measured in an area 0.5-1 disk diameter from the optic disc with semiautomated software [arteriole/venule index (AVIx) calculator]. AVIx was also estimated. Vascular damage was assessed using carotid intima-media thickness and pulse wave velocity, cardiac damage using Cornell voltage-duration product, renal damage using the glomerular filtration rate and microalbuminuria, and cardiovascular risk with the Framingham score.Interobserver intraclass correlation coefficient (ICC) ranged from 0.96 [95% confidence interval (CI) 0.94-0.97] to 0.99 (95% CI 0.98-0.99), and intraobserver ICC ranged from 0.97 (95% CI 0.94-0.98) to 0.99 (95% CI 0.99-0.99). In the Bland-Altman plot, the limit of interobserver agreement was -0.009 (0.066 to -0.086) in right AVIx and -0.001 (0.083 to -0.085) in left AVIx, whereas the limit of intraobserver agreement for overall AVIx was -0.005 (-0.057 to -0.047). Cardiovascular risk and albumin-creatinine ratio were higher in the first tertile of AVIx as compared with the other two (P 0.05). In multiple regression, AVIx and venule caliber, but not artery caliber, behaved as predictors of cardiovascular risk and microalbuminuria.This tool showed a high intraobserver and interobserver reliability, and results of the validity analysis agree with those from large studies in estimation of cardiovascular risk and evaluation of target organ damage.

Osteoprotegerin (OPG), a secreted member of the tumour necrosis factor receptor superfamily of cytokines, has been associated with endothelial dysfunction. We studied in type 2 diabetic and/or hypertensive patients the relationship between serum OPG and vascular alterations associated with these pathologies.We analysed 191 consecutive patients (52 with type 2 diabetes and 139 hypertensive nondiabetic patients) and 54 healthy controls. We assessed the relationship of OPG serum levels measured by ELISA with basal glycaemia, glycosylated haemoglobin, blood pressure, endothelial dysfunction (assessed by pulse wave velocity), retinopathy (by Keith-Wagener classification), left ventricular hypertrophy (by Cornell index), cardiovascular risk and target organs (heart, vascular, kidney) damage.Serum OPG levels were higher in either hypertensive or diabetic patients and in patients with non-dipper and riser circadian blood pressure patterns. We found significant correlations between OPG levels and age, height, glycaemia, systolic, diastolic and pulse blood pressure, pulse wave velocity and left ventricular hypertrophy in both hypertensive and diabetic patients. OPG levels were also higher in hypertensive patients with retinopathy, patients with high probability of 10-year cardiovascular risk, patients with three or more damaged target organs (heart, vessels, kidneys) and patients with previous episodes of ischaemic cardiopathy or hypercholesterolaemia.Osteoprotegerin is an indicator of diabetes- and hypertension-associated vascular pathologies as endothelial dysfunction and cardiovascular risk.

Background Ambulatory blood pressure monitoring (ABPM) shows a better correlation to target organ damage and cardiovascular morbidity-mortality than office blood pressure. A loss of arterial elasticity and an increase in carotid artery intima-media thickness (IMT) has been associated with increased cardiovascular morbidity-mortality. Tools have been developed that allow estimation of the retinal arteriovenous index but not all studies coincide and there are contradictory results in relation to the evolution of the arteriosclerotic lesions and the caliber of the retinal vessels. The purpose of this study is to analyze the relationship between peripheral and central arterial pressure (clinic and ambulatory) and vascular structure and function as evaluated by the carotid artery intima-media thickness, retina arteriovenous index, pulse wave velocity (PWV) and ankle-brachial index in patients with and without type 2 diabetes. In turn, software is developed and validated for measuring retinal vessel thickness and automatically estimating the arteriovenous index. Methods/Design A cross-sectional study involving a control group will be made, with a posterior 4-year follow-up period in primary care. The study patients will be type 2 diabetics, with a control group of non-diabetic individuals. Consecutive sampling will be used to include 300 patients between 34-75 years of age and no previous cardiovascular disease, one-half being assigned to each group. Main measurements: age, gender, height, weight and abdominal circumference. Lipids, creatinine, microalbuminuria, blood glucose, HbA1c, blood insulin, high sensitivity C-reactive protein and endothelial dysfunction markers. Clinic and ambulatory blood pressure monitoring. Carotid ultrasound to evaluate IMT, and retinography to evaluate the arteriovenous index. ECG to assess left ventricle hypertrophy, ankle-brachial index, and pulse wave analysis (PWA) and pulse wave velocity (PWV) with the Sphigmocor System. Discussion We hope to obtain information on the correlation of different ABPM-derived parameters and PWA to organ target damage - particularly vascular structure and function evaluated from the IMT and PWV - and endothelial dysfunction in patients with and without type 2 diabetes. We also hope to demonstrate the usefulness of the instrument developed for the automated evaluation of retinal vascularization in the early detection of alterations in vascular structure and function and in the prognosis of middle-term cardiovascular morbidity.

Presented here are the results of Legionella urinary antigen testing correlated with patient characteristics and severity of pneumonia (Fine score) in 295 patients diagnosed with Legionella pneumonia in connection with a large outbreak in Murcia, Spain. Overall, the sensitivity of the urinary antigen test was 47.7% (141/295). A statistically significant association was found between the clinical severity of pneumonia and test sensitivity; 85.7% for patients with severe pneumonia versus 37.9% for patients with mild pneumonia (risk ratio, 2.3). Variables significantly associated with test positivity in multivariate analysis were as follows: pre-existing pulmonary disease, body temperature40 degrees C, leukocytosis and multilobar infiltrates. Patients with mild pneumonia may go undiagnosed if the urinary antigen test is used alone.

Testosterone and oestradiol can modulate GABA synthesis in sexually regressed goldfish. Here we investigated their effects on the mRNA expression of two isoforms of the GABA synthesizing enzyme glutamate decarboxylase (GAD(65) and GAD(67), EC 4.1.1.15). Full-length GAD clones were isolated from a goldfish cDNA library and sequenced. Goldfish GAD(65) encodes a polypeptide of 583 amino acid residues, which is 77% identical to human GAD(65). Goldfish GAD(67) encodes a polypeptide of 587 amino acid residues and is 82% identical to human GAD(67). Goldfish GAD(65) and GAD(67) are 63% identical. Sexually regressed male and female goldfish were implanted with solid silastic pellets containing testosterone, oestradiol or no steroid. Semiquantitative PCR analysis showed that oestradiol significantly increased GAD(65) mRNA expression in female hypothalamus and telencephalon, while testosterone resulted in a significant increase only in telencephalon. GAD(67) mRNA levels were not affected by steroids in females. In contrast, both steroids induced significant decreases of GAD(65) and GAD(67) mRNA levels in male hypothalamus, but had no effect on GAD mRNA expression in male telencephalon. Our results indicate that modulation of GAD mRNA expression is a possible mechanism for steroid action on GABA synthesis, which may have opposite effects in males and females.

Identification of factors associated with suffering Acute Respiratory Infections (ARI).A descriptive study using a direct survey."El Naranjo" Primary Care team, Area 9 Madrid.362 patients between 0 and 14.362 interviews were carried out, covering items connected with personal background, living conditions, situation and quality of life and activities, 180 patients attending with clinical symptoms of ARI were interviewed, as well as 182 who attended during the same period for other reasons. The profile of the patients interviewed was mainly: females between 6 and 10, with more history of catarrh than any other pathology, and who had taken aspirin to treat symptoms and mainly Penicillin as an aetiological treatment. They lived in homes measuring 100 square metres, with three bed-rooms which were shared in the main by two people, and had one brother aged between 1 and 9.No protective factors against ARI were found in the group of children studied.

Man's environment, natural as well as artificial, may exert a pathogenic influence on man's life, according to which we could divide the population in meteorosensitive (about 60%) and non meteorosensitive. Psychic patients and patients who suffer from certain organic diseases are those ones who more frequently behave as meteorosensitive. We accept this as starting point of our work. In our paper we analysed statistically the relation among different cosmo-meteorologic factors in the incidence of psychiatric emergencies during two years separated by five years and the probable existence of seasonal rhythms in the different studied diagnostic categories. As well as partial results for every diagnostic category we elaborate as final conclusion that these relations have a multifactorial character, that is to say, there are several factors that interact to unchain certain pathology in meteorosensitive people. We emphasize the existence of seasonal cycles in certain psychiatric syndromes. These conclusions are seen specially in personality disorders, suicide attempts, anxiety crisis and disorders, drug addictions and psycho-organic diseases.
