Treatment of American tegumentary leishmaniasis in special populations: a summary of evidence

We aimed to assess and synthesize the information available in the literature regarding the treatment of American tegumentary leishmaniasis in special populations. We searched MEDLINE (via PubMed), EMBASE, LILACS, SciELO, Scopus, Cochrane Library and mRCT databases to identify clinical trials and observational studies that assessed the pharmacological treatment of the following groups of patients: pregnant women, nursing mothers, children, the elderly, individuals with chronic diseases and individuals with suppressed immune systems. The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. The available evidence suggests that the treatments of choice for each population or disease entity are as follows: nursing mothers and children (meglumine antimoniate or pentamidine), patients with renal disease (amphotericin B or miltefosine), patients with heart disease (amphotericin B, miltefosine or pentamidine), immunosuppressed patients (liposomal amphotericin), the elderly (meglumine antimoniate), pregnant women (amphotericin B) and patients with liver disease (no evidence available). The quality of evidence is low or very low for all groups. Accurate controlled studies are required to fill in the gaps in evidence for treatment in special populations. Post-marketing surveillance programs could also collect relevant information to guide treatment decision-making.

Using virtual reality to teach special populations how to cope in crisis: the case of a virtual earthquake

The unique characteristics of special populations such as pre-school children and Down syndrome kids in crisis and their distorted self-image were never studied before, because of the difficulty of crisis reproduction. This study proposes a VR setting that tries to model some special population's behaviour in the time of crises and offers them a training scenario. The sample population consisted of 30 pre-school children and 20 children with Down syndrome. The VR setting involved a high-speed PC, a VPL EyePhone 1, a MR toolkit, a vibrations plate, a motion capture system and other sensors. The system measured and modelled the typical behaviour of these special populations in a Virtual Earthquake scenario with sight and sound and calculated a VR anthropomorphic model that reproduced their behaviour and emotional state. Afterwards one group received an emotionally enhanced VR self-image as feedback for their training, one group received a plain VR self-image and another group received verbal instructions. The findings strongly suggest that the training was a lot more biased by the emotionally enhanced VR self-image than the other approaches. These findings could highlight the special role of the self-image to therapy and training and the interesting role of imagination to emotions, motives and learning. Further studies could be done with various scenarios in order to measure the best-biased behaviour and establish the most natural and affective VR model. This presentation is going to highlight the main findings and some theories behind them.

Targeting Special Populations for Family Preservation: The Influence of Worker Competence and Organizational Culture

Today there are approximately 581,000 children in the United States foster care system. Children of color, one special population group, are disproportionately represented in the foster care system. Family preservation, a program that aims to improve family functioning and thus decrease the need for foster care, has been examined closely. Some researchers believe that family preservation programs have failed partly due to practitioners' inability to target appropriate families (Feldman, 1990; Schuerman, Rzepnicki & Littell, 1994). Additionally, research confirms that children of color are not the target of family preservation services (Denby, Curtis, & Alford, 1998). Improvements in the effectiveness of family preservation will require many types of reform both internal and external to the program. Among the types of internal reform needed is accurate "targeting of services. " Given the overrepresentation of children of color in the foster care system, this group must be among those who are targeted for services. The results of a national survey of 254 family preservation workers reveal a "profile" of the worker who is likely to target special populations, including children of color, for family preservation services. A case is made for service improvements and training to facilitate the "profiled" workers' competencies.

Reaching those most in need: a review of diabetes self-management interventions in disadvantaged populations

There has been increased recognition of the importance of developing diabetes self-management education (DSME) interventions that are effective with under-served and minority populations. Despite several recent studies in this area, there is to our knowledge no systematic review or synthesis of what has been learned from this research. An electronic literature search identified five formative evaluations and ten controlled DSME intervention trials focused on under-served (low-income, minority or aged) populations. The RE-AIM (Reach, Efficacy, Adoption, Implementation, Maintenance) evaluation framework was used to evaluate the controlled studies on the dimensions of reach, efficacy, adoption, implementation, and maintenance. Fifty percent of the studies identified reported on the percentage of patients who participated, and the percentages were highly variable. The methodological quality of the articles was generally good and the short-term results were encouraging, especially on behavioral outcomes. Data on adoption (representativeness of settings and clinicians who participate) and implementation were almost never reported. Studies of modalities in addition to group meetings are needed to increase the reach of DSME with under-served populations. The promising formative evaluation work that has been conducted needs to be extended for more systematic study of the process of intervention implementation and adaptation with special populations. Studies that explicitly address the community context and that address multiple issues related to public health impact of DSME interventions are recommended to enhance long-term results.

[recommendations For Physical Exercise Practice During Pregnancy: A Critical Review].

Physical exercise is recommended for all healthy pregnant women. Regular practice of exercises during pregnancy can provide many physical and psychological benefits, with no evidence of adverse outcomes for the fetus or the newborn when exercise is performed at mild to moderate intensity. However, few pregnant women engage in this practice and many still have fears and doubts about the safety of exercise. The objective of the present study was to inform the professionals who provide care for Brazilian pregnant women about the current recommendations regarding physical exercise during pregnancy based on the best scientific evidence available. In view of the perception that few systematic models are available about this topic and after performing several studies in this specific area, we assembled practical information of interest to both the professionals and the pregnant women. We also provide recommendations about the indications, contraindications, modalities (aerobics, resistance training, stretching and pelvic floor training), frequency, intensity and duration indicated for each gestational trimester. The review addresses physical exercise recommendation both for low risk pregnant women and for special populations, such as athletes and obese, hypertensive and diabetic subjects. The advantages of an active and healthy lifestyle should be always reinforced during and after gestation since pregnancy is an appropriate period to introduce new habits because pregnant women are usually more motivated to adhere to recommendations. Thus, routine exams, frequent returns and supervision are recommended in order to provide new guidelines that will have long-term beneficial effects for both mother and child.

Epidemiological and clinical data of hospitalizations associated with respiratory syncytial virus infection in children under 5 years of age in Spain: FIVE multicenter study.

BACKGROUND Respiratory syncytial virus (RSV) is an important pathogen in lower respiratory tract infections (LRTI) in infants, but there are limited data concerning patients with underlying conditions and children older than 2 years of age. METHODS We have designed a prospective observational multicenter national study performed in 26 Spanish hospitals (December 2011-March 2012). Investigational cases were defined as children with underlying chronic diseases and were compared with a group of previously healthy children (proportion 1:2). Clinical data were compared between the groups. RESULTS A total of 1763 children hospitalized due to RSV infection during the inclusion period were analyzed. Of them, 225 cases and 460 healthy children were enrolled in the study. Underlying diseases observed were respiratory (64%), cardiovascular (25%), and neurologic (12%), as well as chromosomal abnormalities (7·5%), immunodeficiencies (6·7%), and inborn errors of metabolism (3·5%). Cases were statistically older than previously healthy children (average age: 16·3 versus 5·5 months). Cases experienced hypoxemia more frequently (P < 0·001), but patients with respiratory diseases required oxygen therapy more often (OR: 2·99; 95% CI: 1·03-8·65). Mechanical ventilation was used more in patients with cardiac diseases (OR: 3·0; 95% CI: 1·07-8·44) and in those with inborn errors of metabolism (OR: 12·27; 95% CI: 2·11-71·47). This subgroup showed a higher risk of admission to the PICU (OR: 6·7, 95% CI: 1·18-38·04). Diagnosis of pneumonia was more frequently found in cases (18·2% versus 9·3%; P < 0·01). CONCLUSIONS A significant percentage of children with RSV infection have underlying diseases and the illness severity is higher than in healthy children.

Liver safety assessment: required data elements and best practices for data collection and standardization in clinical trials.

A workshop was convened to discuss best practices for the assessment of drug-induced liver injury (DILI) in clinical trials. In a breakout session, workshop attendees discussed necessary data elements and standards for the accurate measurement of DILI risk associated with new therapeutic agents in clinical trials. There was agreement that in order to achieve this goal the systematic acquisition of protocol-specified clinical measures and lab specimens from all study subjects is crucial. In addition, standard DILI terms that address the diverse clinical and pathologic signatures of DILI were considered essential. There was a strong consensus that clinical and lab analyses necessary for the evaluation of cases of acute liver injury should be consistent with the US Food and Drug Administration (FDA) guidance on pre-marketing risk assessment of DILI in clinical trials issued in 2009. A recommendation that liver injury case review and management be guided by clinicians with hepatologic expertise was made. Of note, there was agreement that emerging DILI signals should prompt the systematic collection of candidate pharmacogenomic, proteomic and/or metabonomic biomarkers from all study subjects. The use of emerging standardized clinical terminology, CRFs and graphic tools for data review to enable harmonization across clinical trials was strongly encouraged. Many of the recommendations made in the breakout session are in alignment with those made in the other parallel sessions on methodology to assess clinical liver safety data, causality assessment for suspected DILI, and liver safety assessment in special populations (hepatitis B, C, and oncology trials). Nonetheless, a few outstanding issues remain for future consideration.

The main topics addressed include the methodology of home blood pressure monitoring, its diagnostic and therapeutic thresholds, its clinical applications in hypertension, with specific reference to special populations, and its applications in research. The final section deals with the problems related to the implementation of these recommendations in clinical practice.

Jaundice-Should "yellow" be a red code?

Objective: Jaundice is the clinical manifestation, of hyperbilirubinemia. It is considered as a sign of either a liver disease or, less often, of a hemolytic disorder. It can be divided into obstructive and non obstructive type, involving increase of indirect (non-conjugated) bilirubin or increase of direct (conjugated) bilirubin, respectively, but it can be also manifested as mixed type. Methods: This article updates the current knoweledge concerning the jaundice's etiology, pathophysiological mechanisms, and complications ant treatment by reviewing of the latest medical literature. It also presents an approach of jaundice's treatment and pathogenesis, in special populations as in neonates and pregnant women. Results: The treatment is consistent in the management of the subjective diseases responsible for the jaundice and its complications.The clinical prognosis of the jaundice depends on the etiology. Surgical treatment of jaundiced patients is associated with high mortality and morbidity rates. Studies have shown that the severity of jaundice and the presence of malignant disease are importan risk factors for post-operative mortality. Conclusions: Early detection of jaundice is of vital importance because of its involvement in malignancy or in other benign conditions requiring immediate treatment in order to avoid further complications.

Factores de riesgo para morbilidad materna extrema en gestantes

Introducción: La morbilidad materna extrema es un término usado para definir cualquier condición obstétrica severa que amenaza la vida y requiere una intervención médica urgente con el fin de prevenir la probable muerte materna. Con el presente estudio se pretendió evaluar los factores de riesgo para morbilidad materna extrema en las gestantes del Hospital Universitario Mayor. Metodología Se realizó un estudio de casos y controles, comparando pacientes con MME y sin MME en una relación de 1:1. Se realizó un muestreo aleatorio simple teniendo en cuenta 95% de la población apareadas por diagnóstico de ingreso. Resultados Se incluyeron un total de 110 pacientes (55 en cada grupo). Ambas poblaciones fueron comprables. Ser de estrato socioeconómico bajo (p 0,000), haber tenido 2 o menos partos (p 0,000), ser tipo de sangre negativo (p0.000) realizar entre 0-3 controles prenatales (p 0,000), tener antecedente de preeclampsia (p 0,000), hipotiroidismo (p 0,000), o trastorno bipolar (p 0,000), son factores de riesgo significativos para presentar MME. Entre los factores protectores están tener más de tres partos OR 0,60 (IC95%: 0,17-0,82, p=0,00) y 7 o más controles prenatales OR 0,23 (IC95%: 0,09-0,55, p=0,000). Resultados concordantes con la literatura Discusión: Es importante dar a conocer los resultados del presente estudio para promover las campañas de prevención primaria, secundaria y terciaria con el fin de evitar las altas complicaciones que se pueden presentar en las mujeres en edad fértil de nuestra población.

The role of simulation in intertemporal choices

One route to understanding the thoughts and feelings of others is by mentally putting one's self in their shoes and seeing the world from their perspective, i.e., by simulation. Simulation is potentially used not only for inferring how others feel, but also for predicting how we ourselves will feel in the future. For instance, one might judge the worth of a future reward by simulating how much it will eventually be enjoyed. In intertemporal choices between smaller immediate and larger delayed rewards, it is observed that as the length of delay increases, delayed rewards lose subjective value; a phenomenon known as temporal discounting. In this article, we develop a theoretical framework for the proposition that simulation mechanisms involved in empathizing with others also underlie intertemporal choices. This framework yields a testable psychological account of temporal discounting based on simulation. Such an account, if experimentally validated, could have important implications for how simulation mechanisms are investigated, and makes predictions about special populations characterized by putative deficits in simulating others.

Managing Dual Enrollment Programs: Review of Program Models, Operations, and Outcomes

Universities that offer dual enrollment programs for high school students must manage increasing student demand in the face of changing state legislation. This brief examines how institutions finance their dual enrollment programs, and how they ensure academic rigor as their programs continue to grow. The report also considers how dual enrollment programs ensure that students can transfer credits, and what strategies they use to encourage DE students to matriculate as undergraduates.

Qualidade de vida em idosos

Introdução: Esta tese de doutorado é mais uma contribuição do Grupo de Qualidade de Vida (Centro Brasileiro) do Programa de Pós-Graduação em Ciências Médicas: Psiquiatria, da UFRGS. Esse grupo têm trabalhado em projetos transculturais de elaboração de instrumentos de qualidade de vida (QV) sob a coordenação da Organização Mundial de Saúde. Entre os instrumentos genéricos de QV já desenvolvidos estão o WHOQOL-100 e o WHOQOL-Bref e entre os instrumentos específicos, para populações especiais, estão o WHOQOL-HIV, o WHOQOL-SRPB e, mais recentemente, o WHOQOL-OLD. O desenvolvimento de uma escala de QV para idosos é especialmente importante tendo em vista especificidades deste grupo etário, bem como o aumento da proporção de idosos na população mundial. Objetivos: O objetivo maior deste estudo é desenvolver uma escala de QV para idosos (WHOQOL-OLD). Entretanto, como trata-se de um processo com longa duração de tempo, foram gerados objetivos específicos a partir da revisão da literatura e coleta de dados, que deram origem a 5 artigos, cada um com sua proposta, a saber: artigo 1. Apresentar a metodologia utilizada e os resultados dos grupos focais para avaliação de QV do idoso, artigo 2. Identificar variáveis relevantes na QV de pessoas idosas, artigo 3. Investigar a relação da percepção de QV do idoso com a percepção de QV do idoso na opinião de seu cuidador, artigo 4. Investigar variáveis associadas com percepção subjetiva de saúde em idosos internados e artigo 5. Pesquisar um possível viés nas respostas de idosos no Inventário de Depressão de Beck (BDI). Métodos: O primeiro estudo teve um desenho qualitativo enquanto os demais foram quantitativos. As amostras variaram para cada estudo. Em todos os estudos idosos(as) acima de 60 anos foram entrevistados. Para os estudos 1 e 2, a amostra contou com profissionais da área da saúde (1) e cuidadores (1 e 2). E, para o estudo 5, adultos acima de 18 anos também foram pesquisados. A coleta dos dados foi realizada em hospitais, lares e grupos comunitários, residências e recrutamento utilizando a técnica de "snow-ball" (bola de neve) em que cada sujeito indicava um outro sujeito. Todos os entrevistados preencheram o Termo de Consentimento Informado e, a partir daí, foram convidados a responder acerca de informações sociodemográficas, QV percebida (WHOQOL-100) e sintomatologia depressiva (BDI), com pequena variação para os cuidadores. O último estudo contou apenas com os dados sociodemográficos e com as respostas ao BDI. Resultados: De forma abreviada, os resultados dos 5 artigos confirmam as especificidades do idoso e portanto a necessidade de desenvolvimento de instrumentos específicos para esta população. O artigo 1 teve como resultado a sugestão de novos itens para idosos, a partir das respostas espontâneas e análise dos domínios e facetas do WHOQOL-100. O artigo 2, por sua vez, mostrou associações da percepção de QV geral com níveis de depressão, percepção subjetiva de saúde e sexo. No artigo 3, foi possível verificar uma tendência, em todos os domínios e na medida QV geral, de o cuidador responder pior percepção de QV do idoso do que o próprio idoso cuidado, apesar de algumas concordâncias (domínios físico, nível de independência, meio ambiente e espiritualidade/religião). Também observou-se que a intensidade de depressão do idoso exerceu forte influência tanto na sua própria percepção de QV quanto na percepção do cuidador sobre o idoso. O artigo 4 mostrou uma prevalência alta e não esperada de idosos internados que se percebiam como saudáveis. Foi possível observar, ainda, uma associação significativa entre percepção saudável e menor intensidade de sintomas depressivos, bem como melhor percepção de QV no domínio nível de independência. E por último, o artigo 5 discute o viés da subescala somático e de desempenho nas respostas do idoso ao BDI. Conclusões: Idosos constituem um grupo particular e, como tal, apresentam especificidades relevantes. A avaliação dos idosos em relação às suas percepções de QV está associada a sexo, idade, estado civil, classe social, percepção de saúde e mais fortemente associada a níveis de sintomas depressivos. Explorando o cuidador como avaliador da QV do idoso observou-se uma tendência de o cuidador perceber a QV do idoso pior do que a própria percepção do idoso, apesar de fortes correlações para todos os domínios e na medida QV geral na percepção do par idoso-cuidador. Já na avaliação de percepção de saúde em idosos foi verificada a influência da intensidade dos sintomas depressivos bem como da dimensão independência: quanto menor a intensidade de depressão e quanto maior o nível de independência, maior associação com percepção de saúde entre idosos. Além desses, características próprias da população idosa podem interferir nos resultados do BDI fazendo com que seus achados sejam maximizados por questões somáticas e de desempenho sugerindo pontos de corte especiais para os idosos. Novos estudos são sugeridos a fim de atender a demanda específica do idoso.
