Pesquisa de helmintos em musculatura e serosa abdominal de peixes de importância comercial capturados no litoral norte do Brasil

Com o objetivo de pesquisar a presença de helmintos, suas freqüências e intensidades de infecções, na musculatura e serosa abdominal parietal de peixes de importância comercial beneficiados em Belém-PA, foram examinados 175 exemplares de quatro espécies de peixes capturados no litoral norte do Brasil, sendo três espécies marinhas da Família Sciaenidae – a pescada amarela (Cynoscion acoupa), a pescada-cambuçú (Cynoscion virescens) e a pescadinha-gó ou pescada-foguete (Macrodon ancylodon); e um siluriforme estuarino da Família Ariidae - a uritinga (Arius proops). Os peixes foram mensurados quanto ao seu comprimento corporal padrão, analisou-se a musculatura e a serosa abdominal em mesa de inspeção “candling table” após o filetamento das amostras. Foi encontrado apenas parasitismo por larvas plerocercóides de cestóides da Ordem Trypanorhyncha. Os blastocistos recuperados foram observados quanto a sua morfologia e tamanho, sendo o mesmo realizado com os escólices após a sua liberação. Todas as espécies de peixes analisadas apresentavam indivíduos parasitados, sendo 16% em M. ancylodon, 77,78% em A. proops, 79,17% em C. virescens e 82% em C. acoupa, correspondendo uma freqüência parasitária geral de 61,71% (108 exemplares) e uma intensidade média de infecção de aproximadamente seis larvas por peixe. As freqüências de infecção apresentadas pelas espécies de cestóides foram as seguintes: Callitetrarhynchus gracilis (52,57%), Pterobothrium heteracanthum (13,71%), Poecilancistrium caryophyllum (12%) e Pterobothrium crassicolle (3,43%). Entre os peixes parasitados, 85,19% apresentavam parasitismo na região abdominal (serosa e musculatura abdominal) e 81,48% parasitismo muscular (musculatura abdominal e corporal). A espécie P. heteracanthum preferencialmente parasitou a região abdominal dos peixes e a espécie P. caryophyllum a musculatura. Verificou-se associação significativa (P < 0,01) entre as espécies de peixes analisadas e a freqüência de parasitismo.

A pesca de curral no município de São Caetano de Odivelas-PA

A pesca de curral é uma das artes de pesca mais tradicionais e produtivas da costa paraense e com uma produção que chega a representar 10% da produção pesqueira do Nordeste paraense (Santos et al., 2005). Sua produtividade depende tanto do modo como o curral é feito quanto do local onde é instalado. Para a realização desse trabalho, 12 currais de pesca foram selecionados em relação ao tipo (coração, enfia e cachimbo), ao local de instalação (“de beira” ou “de fora”) e ao tipo de ambiente em que se encontra (beira de rio, beira de praia e banco de areia), foram georreferenciados e tiveram sua produtividade pesqueira acompanhada durante o período de safra (junho, julho e agosto) de 2012. Na comunidade de São João de Ramos, foram monitorados 3 currais de beira do tipo coração, instalados as margens do rio Paruipema, e 3 currais de fora do tipo enfia, instalados em bancos de areia nas praias do rato e do marinheiro. Na comunidade do Aê, foram monitorados os 6 currais classificados como currais de beira, sendo 3 do tipo coração e 3 do tipo cachimbo, e todos se encontravam instalados na praia Ponta de Itaipu. Foram capturados 4.274 indivíduos, distribuídos em 9 ordens, 20 famílias e 43 espécies de peixes. A ordem Perciformes foi a que apresentou o maior número de famílias (10 famílias ou 50% do total), o maior número de espécies (19 ou 44%) e o maior número de indivíduos (3.190 ou 75% do total). As famílias Sciaenidae e Ariidae são as mais abundantes na região tanto em número de espécies quanto em indivíduos. A família Sciaenidae foi a que apresentou o maior número de indivíduos (2.855 ou 67%), mas apresentou menos espécies (8 ou 19%) que a família Ariidae, com 10 espécies ou 23% do total. Das 43 espécies capturadas, as quatro mais representadas foram: Macrodon ancylodon (51%), Arius couma (9%), Cynoscion virescens (9%) e Mugil incilis (4%). A comparação da captura entre os currais e localidades ao longo dos meses de monitoramento indicou que a produção total dos currais diferiu entre os tipos de currais associados com sua localidade.

Patterns of molecular response to and relapse after combination of sorafenib, idarubicin, and cytarabine in patients with FLT3 mutant acute myeloid leukemia

BACKGROUND: FMS-like tyrosine kinase 3 (FLT3) is a class III receptor tyrosine kinase involved in hematopoietic progenitor cell development. Mutations of FLT3 have been reported in about a third of patients with acute myeloid leukemia (AML), and inhibitors of FLT3 are of clinical interest. Sorafenib is an orally active multikinase inhibitor with potent activity against FLT3 and the Raf/ERK/MEK kinase pathway. METHODS: We studied the patterns of molecular response and relapse in 18 patients with mutated FLT3 treated with the combination of sorafenib, idarubicin, and cytarabine. RESULTS: The median follow-up was 9 months. Sixteen patients achieved complete remission (CR), and the other 2 patients achieved CR but lacked platelet recovery for an overall response rate of 100%. Ten patients had their FLT3-mutated clone eradicated, with 6 patients who showed some residual FLT3-mutated cells, and 2 patients who showed persistent FLT3-mutated cells. The elimination of FLT3-mutated population at the time of morphologic CR, however, was not predictive of relapse. After a median follow-up of 9 months (range, 1-16 months), 10 (55%) patients had relapsed, with a median CR duration of 8.8 months (range, 1-9.5 months). By DNA sequencing, there was no evidence of an acquired FLT3 point mutation at the time of relapse in 7 patients tested, which suggested the presence of other mechanisms of sorafenib resistance. CONCLUSION: Sorafenib, combined with chemotherapy, is effective in attaining CR, but relapses still occur.

Incidence and risk factors of homicide-suicide in Swiss households: National Cohort study

BACKGROUND Homicide-suicides are rare but catastrophic events. This study examined the epidemiology of homicide-suicide in Switzerland. METHODS The study identified homicide-suicide events 1991-2008 in persons from the same household in the Swiss National Cohort, which links census and mortality records. The analysis examined the association of the risk of dying in a homicide-suicide event with socio-demographic variables, measured at the individual-level, household composition variables and area-level variables. Proportional hazards regression models were calculated for male perpetrators and female victims. Results are presented as age-adjusted hazard ratios (HR) with 95% confidence intervals (95%CI). RESULTS The study identified 158 deaths from homicide-suicide events, including 85 murder victims (62 women, 4 men, 19 children and adolescents) and 68 male and 5 female perpetrators. The incidence was 3 events per million households and year. Firearms were the most prominent method for both homicides and suicides. The risk of perpetrating homicide-suicide was higher in divorced than in married men (HR 3.64; 95%CI 1.56-8.49), in foreigners without permanent residency compared to Swiss citizens (HR 3.95; 1.52-10.2), higher in men without religious affiliations than in Catholics (HR 2.23; 1.14-4.36) and higher in crowded households (HR 4.85; 1.72-13.6 comparing ≥2 with <1 persons/room). There was no association with education, occupation or nationality, the number of children, the language region or degree of urbanicity. Associations were similar for female victims. CONCLUSIONS This national longitudinal study shows that living conditions associated with psychological stress and lower levels of social support are associated with homicide-suicide events in Switzerland.

International palliative care experts' view on phenomena indicating the last hours and days of life

BACKGROUND Providing the highest quality care for dying patients should be a core clinical proficiency and an integral part of comprehensive management, as fundamental as diagnosis and treatment. The aim of this study was to provide expert consensus on phenomena for identification and prediction of the last hours or days of a patient's life. This study is part of the OPCARE9 project, funded by the European Commission's Seventh Framework Programme. METHOD The phenomena associated with approaching death were generated using Delphi technique. The Delphi process was set up in three cycles to collate a set of useful and relevant phenomena that identify and predict the last hours and days of life. Each cycle included: (1) development of the questionnaire, (2) distribution of the Delphi questionnaire and (3) review and synthesis of findings. RESULTS The first Delphi cycle of 252 participants (health care professionals, volunteers, public) generated 194 different phenomena, perceptions and observations. In the second cycle, these phenomena were checked for their specific ability to diagnose the last hours/days of life. Fifty-eight phenomena achieved more than 80% expert consensus and were grouped into nine categories. In the third cycle, these 58 phenomena were ranked by a group of palliative care experts (78 professionals, including physicians, nurses, psycho-social-spiritual support; response rate 72%, see Table 1) in terms of clinical relevance to the prediction that a person will die within the next few hours/days. Twenty-one phenomena were determined to have "high relevance" by more than 50% of the experts. Based on these findings, the changes in the following categories (each consisting of up to three phenomena) were considered highly relevant to clinicians in identifying and predicting a patient's last hours/days of life: "breathing", "general deterioration", "consciousness/cognition", "skin", "intake of fluid, food, others", "emotional state" and "non-observations/expressed opinions/other". CONCLUSION Experts from different professional backgrounds identified a set of categories describing a structure within which clinical phenomena can be clinically assessed, in order to more accurately predict whether someone will die within the next days or hours. However, these phenomena need further specification for clinical use.

Homicide-suicides compared to homicides and suicides: systematic review and meta-analysis.

Homicide-suicides, the murder of one or several individuals followed by the suicide of the perpetrator, are rare but have devastating effects on families and communities. We did a systematic review and meta-analysis of studies comparing perpetrators of homicide-suicides with perpetrators of simple homicides and suicides and examined the proportion of firearm use and its correlation with firearm availability. We searched Medline and Embase from inception to July 2012 and identified 27 eligible studies. Perpetrators of homicide-suicides were older and more likely to be male and married to or separated from their victims than perpetrator of simple homicides or suicides. Influence of alcohol and a history of domestic violence or unemployment were less prevalent in homicide-suicides than in homicides. The proportion of firearm use in homicide-suicides varied across countries and was highest in the USA, Switzerland and South Africa, followed by Australia, Canada, The Netherlands and England and Wales, with a strong correlation between the use of firearms and the level of civilian gun ownership in the country. Our results indicate that homicide-suicides represent a distinct entity, with characteristics distinguishing them both from homicides and suicides.

Low self-esteem is a risk factor for depressive symptoms from young adulthood to old age

Data from two large longitudinal studies were used to analyze reciprocal relations between self-esteem and depressive symptoms across the adult life span. Study 1 included 1,685 participants aged 18 to 96 years assessed 4 times over a 9-year period. Study 2 included 2,479 participants aged 18 to 88 years assessed 3 times over a 4-year period. In both studies, cross-lagged regression analyses indicated that low self-esteem predicted subsequent depressive symptoms, but depressive symptoms did not predict subsequent levels of self-esteem. This pattern of results replicated across all age groups, for both affective–cognitive and somatic symptoms of depression, and after controlling for content overlap between the self-esteem and depression scales. The results suggest that low self-esteem operates as a risk factor for depressive symptoms at all phases of the adult life span.

Self-esteem development from young adulthood to old age: A cohort-sequential longitudinal study

The authors examined the development of self-esteem from young adulthood to old age. Data came from the Americans’ Changing Lives study, which includes 4 assessments across a 16-year period of a nationally representative sample of 3,617 individuals aged 25 years to 104 years. Latent growth curve analyses indicated that self-esteem follows a quadratic trajectory across the adult life span, increasing during young and middle adulthood, reaching a peak at about age 60 years, and then declining in old age. No cohort differences in the self-esteem trajectory were found. Women had lower self-esteem than did men in young adulthood, but their trajectories converged in old age. Whites and Blacks had similar trajectories in young and middle adulthood, but the self-esteem of Blacks declined more sharply in old age than did the self-esteem of Whites. More educated individuals had higher self-esteem than did less educated individuals, but their trajectories were similar. Moreover, the results suggested that changes in socioeconomic status and physical health account for the decline in self-esteem that occurs in old age.

Brief Report: HIV Testing Among Pregnant Women Who Attend Antenatal Care in Malawi.

Malawi adopted the Option B+ strategy in 2011. Its success in reducing mother-to-child transmission depends on coverage and timing of HIV testing. We assessed HIV status ascertainment and its predictors during pregnancy. HIV status ascertainment was 82.3% (95% confidence interval: 80.2 to 85.9) in the pre-Option B+ period and 85.7% (95% confidence interval: 83.4 to 88.0) in the Option B+ period. Higher HIV ascertainment was independently associated with higher age, attending antenatal care more than once, and registration in 2010. The observed high variability of HIV ascertainment between sites (50.6%-97.7%) and over time suggests that HIV test kit shortages and insufficient numbers of staff posed major barriers to reducing mother-to-child transmission.

Age- and Gender-related Disparities in Primary Percutaneous Coronary Interventions for Acute ST-segment elevation Myocardial Infarction.

BACKGROUND Previous analyses reported age- and gender-related differences in the provision of cardiac care. The objective of the study was to compare circadian disparities in the delivery of primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) according to the patient's age and gender. METHODS We investigated patients included into the Acute Myocardial Infarction in Switzerland (AMIS) registry presenting to one of 11 centers in Switzerland providing primary PCI around the clock, and stratified patients according to gender and age. FINDINGS A total of 4723 patients presented with AMI between 2005 and 2010; 1319 (28%) were women and 2172 (54%) were ≥65 years of age. More than 90% of patients <65 years of age underwent primary PCI without differences between gender. Elderly patients and particularly women were at increased risk of being withheld primary PCI (males adj. HR 4.91, 95% CI 3.93-6.13; females adj. HR 9.31, 95% CI 7.37-11.75) as compared to males <65 years of age. An increased risk of a delay in door-to-balloon time >90 minutes was found in elderly males (adj HR 1.66 (95% CI 1.40-1.95), p<0.001) and females (adj HR 1.57 (95% CI 1.27-1.93), p<0.001), as well as in females <65 years (adj HR 1.47 (95% CI 1.13-1.91), p = 0.004) as compared to males <65 years of age, with significant differences in circadian patterns during on- and off-duty hours. CONCLUSIONS In a cohort of patients with AMI in Switzerland, we observed discrimination of elderly patients and females in the circadian provision of primary PCI.

Retention in care during the first 3 years of antiretroviral therapy for women in Malawi's option B+ programme: an observational cohort study

Background Studies of Malawi's option B+ programme for HIV-positive pregnant and breastfeeding women have reported high loss to follow-up during pregnancy and at the start of antiretroviral therapy (ART), but few data exist about retention during breastfeeding and after weaning. We examined loss to follow-up and retention in care in patients in the option B+ programme during their first 3 years on ART. Methods We analysed two data sources: aggregated facility-level data about patients in option B+ who started ART between Oct 1, 2011, and June 30, 2012, at 546 health facilities; and patient-level data from 20 large facilities with electronic medical record system for HIV-positive women who started ART between Sept 1, 2011, and Dec 31, 2013, under option B+ or because they had WHO clinical stages 3 or 4 disease or had CD4 counts of less than 350 cells per μL. We used facility-level data to calculate representative estimates of retention and loss to follow-up. We used patient-level data to study temporal trends in retention, timing of loss to follow-up, and predictors of no follow-up and loss to follow-up. We defined patients who were more than 60 days late for their first follow-up visit as having no follow-up and patients who were more than 60 days late for a subsequent visit as being lost to follow-up. We calculated proportions and cumulative probabilities of patients who had died, stopped ART, had no follow-up, were lost to follow-up, or were retained alive on ART for 36 months. We calculated odds ratios and hazard ratios to examine predictors of no follow-up and loss to follow-up. Findings Analysis of facility-level data about patients in option B+ who had not transferred to a different facility showed retention in care to be 76·8% (20 475 of 26 658 patients) after 12 months, 70·8% (18 306 of 25 849 patients) after 24 months, and 69·7% (17 787 of 25 535 patients) after 36 months. Patient-level data included 29 145 patients. 14 630 (50·2%) began treatment under option B+. Patients in option B+ had a higher risk of having no follow-up and, for the first 2 years of ART, higher risk of loss to follow-up than did patients who started ART because they had CD4 counts less than 350 cells per μL or WHO clinical stage 3 or 4 disease. Risk of loss to follow-up during the third year was low and similar for patients retained for 2 years. Retention rates did not change as the option B+ programme matured. Interpretation Our data suggest that pregnant and breastfeeding women who start ART immediately after they are diagnosed with HIV can be retained on ART through the option B+ programme, even after many have stopped breastfeeding. Interventions might be needed to improve retention in the first year on ART in option B+.
