Triatoma rubrovaria (Blanchard, 1843) (Hemiptera, Reduviidae, Triatominae) II: trophic resources and ecological observations of five populations collected in the State of Rio Grande do Sul, Brazil

Triatoma rubrovaria has become the most frequently captured triatomine species after the control of T. infestans in the State of Rio Grande do Sul (RS), Brazil. Isoenzymatic and chromatic studies indicate the existence of, at least, two distinct phenotypic patterns of T. rubrovaria in RS. The geographic variation noted through molecular tools may also result in distinct profiles of vectorial potentiality. In order to enhance our understanding of the bionomic knowledge of T. rubrovaria separate batches of the species were collected from different municipalities of RS distant from 72 to 332 km: Santana do Livramento (natural ecotope), Santana do Livramento (artificial ecotope), Santiago (natural ecotope), Canguçu (peridomicile) and Encruzilhada do Sul (natural ecotope). A total of 285 specimens were collected, 85 specimens kept sufficient fecal material in their guts for the precipitin analysis. The results indicated the food eclecticism for this species and the anti-rodent serum showed the highest positivity in most localities. From the total of analyzed samples, only 1.3% of unique positivity for human blood was registered, all of them for Santiago population. This reactivity to human blood may be associated to pastures activities in the field.

Morphometric discrimination of females of five species of Anopheles of the subgenus Nyssorhynchus from Southern and Northwest Colombia

The most important vectors of human Plasmodium in the neotropics belong to the subgenus Nyssorhynchus. These species are generally sympatric in terms of their geographical distributions. Some are difficult to identify based solely on examination of adult females using the available morphological keys, in these cases examination of immature stages and male genitalia is required to make correct determinations. However, in epidemiological studies it is necessary to identify the species of adult females which are found near humans, i.e. in studies of malaria transmission or evaluation of control measures. The purpose of the present study was to evaluate the discrimination of adult females of different species of Nyssorhynchus isolated mainly from Southern Colombia (department of Putumayo), using morphometric analysis. Adult females were obtained after rearing larvae collected in natural breeding places and from the progeny of females collected on humans. The morphological characteristics of the immature stages allowed the identification of four species of the subgroup Oswaldoi from Southern Colombia: Anopheles rangeli Gabaldon, Cova Garcia & Lopez, An. oswaldoi (Peryassu), An. benarrochi Gabaldon, Cova Garcia & Lopez and An. triannulatus (Neiva & Pinto). The species An. nuneztovari (Gabaldon) from the Northwest of Colombia was included for comparison. Morphometric analysis allowed differentiation of the females of all species to a confidence level approaching 90% using principal components analysis of 10 wing and leg variables, followed by canonical variate analysis of the first four principal components. We conclude that morphometrics may represent a useful taxonomic tool for this group and that its use should be further studied.

Five new CYLD mutations in skin appendage tumors and evidence that aspartic acid 681 in CYLD is essential for deubiquitinase activity.

Brooke-Spiegler syndrome, familial cylindromatosis, and familial trichoepithelioma are autosomal-dominant genetic predispositions for benign tumors of skin appendages caused by mutations in the CYLD gene localized on chromosome 16q12-q13. The encoded protein functions as ubiquitin-specific protease (UBP), which negatively regulates NF-kappaB and c-Jun N-terminal kinase (JNK) signaling. We investigated five families affected with these skin neoplasms and identified four premature stop codons and the novel missense mutation D681G in a family in which 11 of 12 investigated tumors were trichoepitheliomas. CYLD protein harboring this missense mutation had a significant reduced ability to inhibit TNF receptor-associated factor (TRAF)2- and TRAF6-mediated NF-kappaB activation, tumor necrosis factor-alpha (TNFalpha)-induced JNK signaling, and to deubiquitinate TRAF2. CYLD-D681G was coimmunoprecipitated by TRAF2, but was unable to cleave K63-linked polyubiquitin chains. Aspartic acid 681 is highly conserved in CYLD homologues and other members of the UBP family, but does not belong to the Cys and His boxes providing the CYLD catalytic triad (Cys601, His871, and Asp889). As reported previously, the homologous residue D295 of HAUSP/USP-7 forms a hydrogen bond with the C-terminal end of ubiquitin and is important for the enzymatic activity. These results underline that D681 in CYLD is required for cleavage of K63-linked polyubiquitin chains.

Isoenzymatic variability among five Anopheles species belonging to the Nyssorhynchus and Anopheles subgenera of the Amazon region, Brazil

An isoenzymatic comparative analysis of the variability and genetics differentiation among Anopheles species was done in populations of An. (Nys.) intermedius and An. (Ano.) mattogrossensis of the Anopheles subgenus, and of An. darlingi, An. albitarsis and An. triannulatus of the Nyssorhynchus subgenus, with the aim of detecting differences between both subgenera and of estimating the degree of genetic intere specific divergence. Samples from Macapá, State of Amapá and Janauari Lake, near Manaus, State of Amazonas, were analyzed for eight isoenzymatic loci. Analysis revealed differences in the average number of alleles per locus (1.6-2.3) and heterozygosity (0.060-0.284). However, the proportion of polymorphic loci was the same for An. (Nys.) darlingi, An. (Nys.) triannulatus and An. (Ano.) mattogrossensis (50%), but differed for An. (Nys.) albitarsis (62.5%) and An. (Ano.) intermedius (25%). Only the IDH1 (P > 0.5) locus in all species studied was in Hardy-Weinberg equilibrium. The fixation index demonstrated elevated genetic structuring among species, based on values of Fst = 0.644 and genetic distance (0.344-0.989). Genetic difference was higher between An. (Nys.) triannulatus and An. (Ano.) intermedius (0.989) and smaller between An. (Nys.) albitarsis sensu lato and An. (Nys.) darlingi (0.344). The data show interspecific genetic divergence which differs from the phylogenetic hypothesis based on morphological characters.

La personnalité comme facteur prédictif des symptômes comportementaux et psychologiques chez les patients qui présentent des troubles cognitifs légers

Background and Aims: Both personality changes and behavioural and psychological symptoms (BPS) may be associated with mild cognitive impairment (MCI) in later life and help identify incipient dementia. We wished to investigate the links between personality and BPS in MCI. Method: We studied premorbid personality traits as estimated five years back and their changes in 83 control subjects and 52 MCI patients using the NEO-PI-R for the Five-Factor Model completed by a proxy. Information on BPS was obtained using the Neuropsychiatrie Inventory (NPI). Analyses were controlled for current depression and anxiety. Results: premorbid neuroticism and openness to experience were associated with the total NPI score. The changes in neuroticism, extraversion, openness to experiences, and conscientiousness were associated with apathy and affective symptoms. Conclusions: Personality changes and BPS occur in MCI. The occurrence of affective BPS and apathy is associated with both premorbid personality and their changes. - Cette thèse a eu pour objectif d'étudier l'impact des traits de la personnalité sur le développement de symptômes comportementaux et psychologiques (SCP) chez des personnes qui présentent de troubles cognitifs légers (Mild Cognitive Impairment ou MCI) par rapport à un groupe de sujets contrôle en bonne santé sans troubles cognitifs. Cette thèse s'est s'inserite dans une étude plus large regroupant des aspects neuropsychologiques, génétiques et des marqueurs structuraux cérébraux d'imagerie chez les mêmes participants. La découverte d'un MCI a un impact important en soulevant la question d'éventuels traitements préventifs et de modification du cours d'un trouble ou d'une maladie sous-jacente. Les manifestations cliniques, notamment les SCP, sont source de souffrance chez le patient et les proches et la première cause d'institutionnalisation. Connaître les liens entre la personnalité et les SCP chez les patients qui présentent un MCI s'avère primordial si l'on veut les détecter précocement et favoriser un traitement mieux adapté, tant pharmacologique que psychothérapeutique, pour tenter de freiner leur impact sur l'évolution de la maladie. Nous avons comparé 52 patients MCI avec 83 sujets contrôles. La personnalité au moment de l'étude et estimée rétrospectivement à cinq ans en arrière a été évalué par un proche à l'aide du NEO-PI-R, principal instrument basé sur le Five Factor Model. Pour évaluer la présence de SCP nous avons utilisé l'inventaire neuropsychiatrique (NPI-Q). Les analyses ont étés contrôlées en tenant compte des principales variables confondantes. Le groupe MCI présente des traits de personnalité prémorbide différents de ceux des participants contrôles avec des niveaux inférieurs d'ouverture à l'expérience, d'agréabilité et de conscience. Les changements de personnalité sont marqués chez les MCI avec une augmentation du névrosisme et une diminution de l'extraversion et de la conscience. La personnalité est restée stable chez le groupe contrôle. Le groupe MCI présente souvent des SCP, en particulier des symptômes affectifs (dépression, anxiété, irritabilité, troubles du sommeil) et de l'apathie tandis que les SCP sont presqu'inexistantes chez le groupe contrôle. Les valeurs de névrosisme plus élevés et l'ouverture à l'expérience plus basses sont associées à la présence de SCP. En plus, le changement de la personnalité, à savoir l'augmentation du névrosisme et la diminution de conscience sont associées à la présence de SCP, aux symptômes affectifs et à l'apathie. La diminution d'extraversion et d'ouverture à l'expérience sont associées à la présence de SCP, aux symptômes affectifs mais pas à l'apathie. Cette étude montre que la personnalité change déjà au stade de MCI et que l'apparition des SCP affectifs et de l'apathie est précoce. Certains profils prémorbides et changements de personnalité sont associés à la présence de SCP. L'évaluation de ces changements peut favoriser le diagnostic précoce des troubles cognitifs. Des études prospectives sur des patients MCI sont essentielles afin d'approfondir la compréhension des facteurs de risque liés à la personnalité sur le déclin cognitif et les SCP associés.

Simple steps to a healthy heart

The number of deaths from coronary heart disease in Northern Ireland has dropped significantly, according to recent figures. However, the Public Health Agency is urging everyone to take steps to protect their heart and reduce their chances of developing the disease during National Heart Month (February).Despite the number of deaths dropping significantly in recent years, coronary heart disease is still the number one killer across the country. Over 2,200 people died in Northern Ireland from coronary heart disease in 2010 compared to just over 2,300 people in 2009 - an overall reduction of 100 province-wide. The latest figure reveals the positive downward trend is continuing - in 2008, there were 2,410 deaths, 2,493 in 2007 and 2,554 in 2006, while in 1979 there were nearly 5,000 deaths. Throughout National Heart Month in February, the PHA is calling for people to follow a number of steps in a bid to reduce their chances of developing the disease.Smoking is a major risk factor and, the more cigarettes you smoke, the higher the risk, according to Dr Christine McMaster, Consultant in Public Health Medicine, with responsibility for cardiovascular disease in the PHA."The reduction in smoking over the past number of years through public education, stop smoking programmes and smoke free legislation has had a major impact on reducing deaths from heart disease. However, 24% of the population in Northern Ireland still smoke, putting them at risk of developing the disease."People who suffer from high blood pressure also run an increased risk of developing coronary heart disease. High blood pressure is a silent, but treatable condition. In order to minimise the risk, I would urge everyone over the age of 45 to have their blood pressure measured every five years by their GP," said Dr McMaster.Simple lifestyle changes will also reduce the risk of heart disease, including eating at least five servings of fruit and vegetables a day, avoiding saturated fats, limiting alcohol intake and taking at least 30 minutes of exercise a day, five days a week.Dr McMaster described the reduction in deaths from coronary heart disease over the past few years as "a big success story". "It shows that people can take very positive steps to reduce their risk of heart disease by getting their blood pressure checked and adopting a healthier lifestyle; in particular by not smoking," he added. "The message is clear during National Heart Month - you only have one heart and you can take steps to keep it healthy."

Five Years Of Denosumab Treatment In Women With Postmenopausal Osteoporosis: Preliminary Results From The Freedom Extension Study

Aims: The pivotal FREEDOM study evaluated the effi cacy and safety of 3 years' denosumab treatment in women with postmenopausal osteoporosis (PMO).1 Since osteoporosis is a chronic condition requiring long-term therapy, FREEDOM was extended to further elucidate the safety and effi cacy of long-term denosumab administration. We present data from the fi rst 2 years of this extension, representing up to 5 years' continuous exposure to denosumab.Methods: Patients who completed FREEDOM were eligible for the extension. Women continued to receive (long-term group), or started after 3 years' placebo (cross-over group), denosumab 60 mg sc every 6 months and daily calcium and vitamin D. These data refl ect 5 years' (long-term) or 2 years' (cross-over) continuous denosumab treatment. Effi cacy measures include changes in BMD from extension study baseline and bone turnover markers (BTM). P-values are descriptive.Results: Of the 83.0% of subjects who completed FREEDOM, 70.2% (N = 4550) agreed to participate in the extension (long-term: 2343; cross-over: 2207). In the long-term group, there were further signifi cant gains (P < 0.0001) in BMD in years 4 and 5: 1.9% and 1.7% at the lumbar spine to a total of 13.7% from FREEDOM baseline and 0.7% and 0.6% at the total hip to a total of 7.0%. During their fi rst 2 years' denosumab treatment, women in the cross-over group had signifi cant improvements in lumbar spine (7.9%) and total hip BMD (4.1%) (P < 0.0001). Serum C-telopeptide (CTX) was rapidly reduced following denosumab dosing in both groups, with the characteristic attenuation of CTX reduction observed at the end of the dosing interval. A low incidence of new vertebral and nonvertebral fractures was reported for both groups. The denosumab safety profi le did not change over time.Conclusions: Denosumab treatment for up to 5 years in women with PMO remains well tolerated, maintains reduction of BTMs and continues to significantly increase BMD.Reference1.

Couch Potato to Runner Bean

To coincide with the start of National Obesity Awareness Week, the Public Health Agency is today urging people to take up the challenge 'From Couch Potato to Runner Bean in 10 weeks'.The PHA, in partnership with five local councils in the western area, will roll out a number of community obesity challenges and programmes between now and March.The challenges and programmes focus on building up physical activity in a gradual and healthy way. At the end of the ten week programme, participants will be encouraged to take part in a five kilometre or 10 kilometre walk, jog or run.Colette Brolly, the PHA Lead on Physical Activity, said: "It is hoped the programmes will influence behaviour changes in those who don't currently take part in physical activity. The beginning of a new year is a great time for a new start and a new challenge, and the resolution to get fit and healthy is a fantastic way to start 2014."She added: "Being physically active helps maintain a healthy weight and can reduce the risk of many diseases including heart disease, type 2 diabetes, breast cancer, and colon cancer. Being active is also good for your mental health and can lift mood, reduce anxiety and help to protect against depression. If you introduce changes in your life to increase physical activity, you will see big differences to your health and wellbeing."'Couch Potato to Runner Bean in Ten Weeks' supports the work of the PHA's Choose to Live Better campaign which aims to tackle obesity. PHA Health Improvement staff and council staff will also be encouraged to participate in the new obesity challenge.In addition to the new programmes being rolled out in the western area, the PHA currently supports a number of running initiatives that are available in other council areas in Northern Ireland.To find out more about getting involved in running see www.nhs.uk/Livewell/c25k/Pages/get-running-with-couch-to-5k.aspx

Personality factors and alcohol use: a mediator analysis of drinking motives.

Current evidence on the association between personality factors, drinking motives, and alcohol use comes exclusively from North America. The present study, however, is based on a sample of 2090 Swiss college students (mean age 23.5, SD = 2,9) and investigates by means of structural equation modeling whether drinking motives mediate the association between personality factors and alcohol use. The results revealed that extraversion was positively related to drinking for enhancement motives; conscientiousness was negatively related to both enhancement and coping motives; and neuroticism was positively related to drinking for coping motives. The association between extraversion and alcohol use was mediated by enhancement motives, while the negative association between conscientiousness and alcohol use was partially mediated by both enhancement and coping motives. This concurs with the findings of North American studies. However, in contrast to these findings, our study finds that coping motives attenuate the "protective" effect of neuroticism with regard to alcohol use. Taken together, the study indicates that alcohol use serves specific purposes depending on particular personality traits. The finding that personality-related effects are partially mediated by motives increases the likelihood that motive-based preventive efforts will help reduce alcohol use among young adults who display particular personality traits.

Palliative Care - A Five Year/Medium Term Development Framework

This document details the HSE's Palliative Care Services - Five Year Medium Term Development Framework (2009 - 2013). It has been developed using a holistic, system-wide, approach to addressing the level of need identified by both the Baseline Study on the Provision of Hospice / Specialist Palliative Care Services in Ireland (2006) as well as the HSE Audit of Palliative Care Service Provision (2007). The HSE Audit was conducted by each of the four HSE Administrative Areas, in conjunction with Area Development Committees, against the recommendations of the Report of the National Advisory Committee on Palliative Care 2001 (the NACPC Report). Therefore, this document is grounded in the recommendations of the NACPC Report, (e.g. palliative care definition, palliative care service areas, staffing and bed number ratios), and informed by the findings of the HSE Audit. The purpose of this document is not to replace the recommendations of the NACPC Report from a policy context, nor does it represent a new national strategy for palliative care. This document details the required actions and initiatives necessary to address the gaps in palliative care service provision, against the recommendations set out in the NACPC Report.

Evaluation of five screening tests licensed in Argentina for detection of hepatitis C virus antibodies

This study was conducted to compare among the most recent generation of five screening tests licensed in Argentina, in order to evaluate which of the tests has the best sensitivity for detection of antibodies against hepatitis C virus (HCV). The tests analyzed were: Detect-HCV™ (3.0) Biochem ImmunoSystems, Canada; Hepatitis C EIA Wiener Lab., Argentina; Equipar HCV Ab, Italy; Murex HCV 4.0, UK and Serodia-HCV particles agglutination test, Japan. The results obtained showed high discrepancy between the different kits used and show that some of the tests assessed have a low sensitivity for anti-HCV detection in both chronic infections and early seroconversion, and indicate that among the commercially available kits in Argentina, Murex HCV 4.0 (UK) and Serodia-HCV particles agglutination test (Japan) have the best sensitivity for HCV screening. Although the sensitivity of the assays is the first parameter to be considered for blood screening, more studies should be carried out to assess the specificity of such assays.
