Validity and applicability of the Mini International Neuropsychiatric Interview administered by family medicine residents in primary health care in Brazil

Objective: To evaluate the validity and applicability of the Mini International Neuropsychiatric Interview (MINI) used by family medicine residents in primary health care (PHC) in Brazil. Methods: Training for administrating the MINI was given as part of a broad psychiatry education program. Interviews were held with 120 PHC patients who were at least 15 years old. MINI was administered by 25 resident physicians, while the Structured Clinical Interview for Diagnosis (SCID) was administered by a psychiatrist blind to patients` results on the MINI, and the diagnoses on both interviews were compared. The resident physicians answered questions on the applicability of the MINI. Results: Concordance levels for any mental disorder, the broader current diagnostic categories and the most common specific diagnoses were analyzed. Kappa coefficients ranged between 0.65 and 0.85; sensitivity, between 0.75 and 0.92; specificity, between 0.90 and 0.99; positive predictive values (PPV), between 0.60 and 0.86; negative predictive values (NPV), between 0.92 and 0.99; and accuracy, between 0.88 and 0.98. The resident physicians considered MINI comprehensibility and clinical relevance satisfactory. Conclusions: These good psychometric results in a real-world setting may be related to a special training program, which is more frequent, intensive and diversified. In these conditions, the MINI is a useful tool for general practitioners. (c) 2008 Elsevier Inc. All rights reserved.

The improvement of care for paediatric and congenital cardiac disease across the World: a challenge for the World Society for Pediatric and Congenital Heart Surgery

The diagnosis and treatment for paediatric and congenital cardiac disease has undergone remarkable progress over the last 60 years. Unfortunately, this progress has been largely limited to the developed world. Yet every year approximately 90% of the more than 1,000,000 children who are born with congenital cardiac disease across the world receive either suboptimal care or are totally denied care. While in the developed world the focus has changed from an effort to decrease post-operative mortality to now improving quality of life and decreasing morbidity, which the focus of this Supplement, the rest of the world still needs to develop basic access to congenital cardiac care. The World Society for Pediatric and Congenital Heart Surgery [http://www.wspchs.org/] was established in 2006. The Vision of the World Society is that every child born anywhere in the world with a congenital heart defect should have access to appropriate medical and surgical care. The Mission of the World Society is to promote the highest quality comprehensive care to all patients with pediatric and/or congenital heart disease, from the fetus to the adult, regardless of the patient`s economic means, with emphasis on excellence in education, research and community service. We present in this article an overview of the epidemiology of congenital cardiac disease, the current and future challenges to improve care in the developed and developing world, the impact of the globalization of cardiac surgery, and the role that the World Society should play. The World Society for Pediatric and Congenital Heart Surgery is in a unique position to influence and truly improve the global care of children and adults with congenital cardiac disease throughout the world [http://www.wspchs.org/].

Nutrition Therapy in a Pediatric Intensive Care Unit: Indications, Monitoring, and Complications

Background: Nutrition therapy (NT) is essential for the care of critically ill children. Inadequate feeding leads to malnutrition and may increase the patient`s risk of morbidity and mortality. The aim of this study was to describe the NT used in a tertiary pediatric intensive care unit (PICU). Methods: The authors evaluated NT administered to 90 consecutive patients who were hospitalized for 7 days in the PICU of Instituto da Crianca, Hospital das Clinicas, Universidade de Sao Paulo, Brazil. NT was established according to the protocol provided by the institution`s NT team. NT provided a balance of fluids and nutrients and was monitored with a weekly anthropometric nutrition assessment and an evaluation of complications. Results: NT was initiated, on average, within 72 hours of hospitalization. Most children (80%) received enteral nutrition (EN) therapy; of these, 35% were fed orally and the rest via nasogastric or postpyloric tube. There were gastrointestinal complications in patients (5%) who needed a postpyloric tube. Parenteral nutrition (PN) was used in only 10% of the cases, and the remaining 10% received mixed NT (EN + PN). The average calorie and protein intake was 82 kcal/kg and 2.7 g/kg per day. Arm circumference and triceps skinfold thickness decreased. Conclusions: The use of EN was prevalent in the tertiary PICU, and few clinical complications occurred. There was no statistically significant change in most anthropometric indicators evaluated during hospitalization, which suggests that NT probably helped patients maintain their nutrition status.

Could sudden death syndrome (SDS) in chickens (Gallus gallus) be a valid animal model for sudden unexpected death in epilepsy (SUDEP)?

Epilepsy is the most common serious neurological disorder and approximately 1% of the population worldwide has epilepsy. Moreover, sudden unexpected death in epilepsy (SUDEP) is the most important direct epilepsy-related cause of death. Information concerning fisk factors for SUDEP is conflicting, but potential risk factors include: young age, early onset of epilepsy, duration of epilepsy, uncontrolled seizures, seizure frequency, AED number and winter temperatures. Additionally, the cause of SUDEP is still unknown; however, the most commonly suggested mechanisms are cardiac abnormalities during and between seizures. Similarly, sudden death syndrome (SDS) is a disease characterized by an acute death of well-nourished and seeming healthy Gallus gallus after abrupt and brief flapping of their wings and incidence of SDS these animals has recently increased worldwide. Moreover, the exactly cause of SDS in Gallus gallus is unknown, but is very probable that cardiac abnormalities play a potential role. Due the similarities between SUDEP and SDS and as Gallus gallus behavioral manifestation during SDS phenomenon is close of a tonic-clonic seizure, in this paper we suggest that epilepsy could be a new possible causal factor for SDS.

Ecological aspects of the free-living ticks (Acari: Ixodidae) on animal trails within Atlantic rainforest in south-eastern Brazil

In a recent ecological study of the ticks on animal trails within an area of Atlantic rainforest in south-eastern Brazil, Amblyomma aureolatum, A. brasiliense, A. incisum, A. ovale and Haemaphysalis juxtakochi were found questing on the vegetation. Most of the ticks recorded by a small, man-made dam on the forest border were A. dubitatum but a few A. brasiliense and A. cajennense, one A. incisum and one H. juxtakochi were also found. The seasonal activity of the ticks indicated that A. incisum and A. brasiliense had one generation/year. On the animal trails, most tick species and stages quested on the vegetation at a height of 30-40 cm above ground level. The questing larvae and adults of A. incisum tended to be found higher, however, with the greatest numbers recorded 40-50 cm (larvae) or 60-70 cm (adults) above ground level. Most of the adult ticks (81.1% -100%), nymphs (78.6%-100%) and larval clusters (100%) found on a forest trail remained questing at the same location over a 24-h period. Carbon-dioxide traps in the rainforest attracted, 50% of the ticks observed questing on the nearby vegetation and, curiously, the CO(2) traps set deep in the forest attracted far fewer ticks than similar traps set by the dam. The ecological relationships between the ticks, their hosts and the rainforest environment are discussed.

Impacts of Animal Traffic on the Brazilian Amazon Parrots (Amazona species) Collection of the Quinzinho de Barros Municipal Zoological Park, Brazil, 1986-2007

Eleven species of Amazon parrots (genus Amazona) are known to occur in Brazil, and nest poaching and illegal traffic pose serious conservation threats to these species. When the illegal owners realize these animals are incompatible with their expectations and lifestyle, or when the police arrests traders and owners, these trafficked animals are often considered unfit for release and sent to local zoos and captive breeders. A retrospective survey of animal and necropsy records from 1986 to 2007 was used to evaluate the impacts of animal traffic on the population composition and mortality patterns of Amazon parrots at the Quinzinho de Barros Municipal Zoological Park, Sorocaba, Brazil. Data were obtained for 374 Amazon parrots of ten Brazilian species, and there was evidence that the studied population could be split into two major groups: a majority belonging to the Amazona aestiva species and a minority belonging to the remaining species. In comparison, the animals of the first group were more frequently admitted from traffic-related origins (98 vs. 75%), had a shorter lifespan (median 301 days vs. 848 days) and a higher mortality within the first year postadmission (54 vs. 37%), were less likely to receive expensive treatments, and were more frequently housed off-exhibit. On an average, parrots were found to have a short postadmission lifespan (median 356 days), with 92.5% of the birds dying within their first five years in captivity. The paper discusses the difficult dilemmas these incoming traffic-related animals pose to zoo management and official anti-traffic policies. Zoo Biol 29:600-614, 2010. (C) 2010 Wiley-Liss, Inc.

Metalloproteinase inhibition protects against cardiomyocyte injury during experimental acute pulmonary thromboembolism

Objectives: Up-regulated matrix metalloproteinases may be involved in the development of cardiomyocyte injury and the degradation of troponin associated with acute pulmonary thromboembolism. We examined whether pretreatment with doxycycline (a nonspecific matrix metalloproteinase inhibitor) protects against cardiomyocyte injury associated with acute pulmonary thromboembolism. Design: Controlled animal study. Setting: University research laboratory. Subjects: Mongrel dogs. Interventions: Anesthetized animals received doxycycline (10 mg/kg intravenously) or saline and acute pulmonary thromboembolism was induced with autologous blood clots injected into the right atrium. Control animals received doxycycline (or saline). Measurements and Main Results: Hemodynamic measurements were performed, and acute pulmonary thromboembolism increased baseline mean pulmonary arterial pressure and pulmonary vascular resistance by approximately 160% and 362%, respectively (both p<.05), 120 mins after acute pulmonary thromboembolism. Pretreatment with doxycycline attenuated these increases (to 125% and 232%, respectively; both p<.05). Although acute pulmonary thromboembolism tended to increase the right ventricle maximum rate of isovolumic pressure development and the maximum rate of isovolumic pressure decay, doxycycline produced no effects on these parameters. Gelatin zymograms of right ventricle showed that acute pulmonary thromboembolism marginally increased matrix metalloproteinase-9 (but not matrix metalloproteinase-2) levels in the right ventricle. A fluorometric assay to assess net matrix metalloproteinase activities showed that acute pulmonary thromboembolism increased matrix metalloproteinase activities in the right ventricle by >100% (p<.05), and this finding was confirmed by in situ zymography of the right ventricle. Doxycycline attenuated acute pulmonary thromboembolism-induced increases in right ventricle matrix metalloproteinase activities. Acute pulmonary thromboembolism induced neutrophil accumulation in the right ventricle, as estimated by myeloperoxidase activity, and doxycycline blunted this effect (p<.05). Serum cardiac troponin I concentrations, which reflect cardiomyocyte injury, increased after acute pulmonary thromboembolism, and this increase was attenuated by pretreatment with doxycycline (p<.05). Conclusions: We found evidence supporting the idea that acute pulmonary thromboembolism is associated with increased matrix metalloproteinase activities in the right ventricle, which may lead to degradation of sarcomeric proteins, including cardiac troponin I. Inhibition of matrix metalloproteinases may be an effective therapeutic intervention in the management of acute pulmonary thromboembolism. (Crit Care Med 2011; 39: 349-356)
