Abstract: the bacterial community associated with the midgut of three brazilian lutzomyia longipalpis (lutz & neiva) populations, two from endemic areas for visceral leishmaniasis (jacobina, bahia state and s?o luís, maranh?o state) and one from a non-endemic area (lapinha cave, minas gerais state), was identified. five groups, 35 females each, from each population were separated; a total of 175 females per collecting area were analyzed. the species identification was based on molecular and traditional bacteriological methods. all bacteria were either affiliated to non-enterobacteriaceae, such as acinetobacter, burkholderia, flavimonas, pseudomonas and stenotrophomonas, or and to enterobacteriaceae, such as citrobacter, enterobacter, escherichia, klebsiella, serratia, pantoea, morganella and weeksella. stenotrophomonas was found to be associated with all three populations studied. in addition, serratia spp., which are well documented as laboratory contaminant of insects, were detected only in the jacobina population. we also discuss the impact of the colonization of insect gut by bacteria on the development and transmission of pathogens.

Open Journal of Genetics (OJGen) , 2012, DOI: 10.4236/ojgen.2012.21010
Abstract: Childhood survivors of acute lymphoblastic leukemia (ALL) are increased risk of several chronic complications, such as second cancers, pulmonary, metabolic complications and cardiovascular disease. Obesity and metabolic syndrome is one of the most common treatment related complication in children surviving cancer, which concurs with our nations childhood epidemic [1-3] Recent research has identified the role of genetics in the development of obesity and metabolic syndrome in childhood survivors of ALL. Growth hormone deficiency, Leptin regulation, fat mass obesity (FTO) gene and the insulin resistant ENPP1 variants disorders has been associated adverse effects of chemotherapeutic treatment and the cause of clinical manifestations of metabolic syndrome [4-8]. The illumination of the role of genetic variants can shed insights into obesity within high risk population, as well as, a target to prevent disease.
Brothers from Different Mothers—Confucius, Benedict, and Francis: The Historical Search for Humane Leadership  [PDF]
Cheryl Crozier Garcia
Journal of Human Resource and Sustainability Studies (JHRSS) , 2013, DOI: 10.4236/jhrss.2013.13006
Abstract: Ongoing global economic downturn, social and political upheavals, revolutionary changes in technology, and frightening climate change are having massive impacts on the ways people live and work. This paper examines the teachings of 3 of these leaders: Confucius, Benedict of Nursia, and Francis of Assisi, whose teachings may inform the ways in which today’s leaders motivate a workforce and deal with uncertainty. Though separated by both time and culture, these 3 men shared common biographical traits that informed their teachings and shaped their ideas about appropriate behaviors for leaders and their subordinates. Compassion, sincerity, wisdom, and trust are traits that all 3 stress as vital for leaders trying to accomplish meaningful goals in the face of adversity.

Abstract: American cutaneous leishmaniasis (ACL) is a focal disease whose surveillance and control require complex actions. The present study aimed to apply integrated tools related to entomological surveillance, environmental management, and health education practices in an ACL-endemic area in Rio de Janeiro city, RJ, Brazil. The distribution of the disease, the particular characteristics of the localities, and entomological data were used as additional information about ACL determinants. Environmental management actions were evaluated after health education practices. The frequency of ACL vectors Lutzomyia (N.) intermedia and L. migonei inside and outside houses varied according to environment characteristics, probably influenced by the way of life of the popular groups. In this kind of situation environmental management and community mobilization become essential, as they help both specialists and residents create strategies that can interfere in the dynamics of vector’s population and the contact between man and vectors. 1. Introduction American cutaneous leishmaniasis (ACL) is among the six most important infectious diseases and the 15 most neglected diseases of the world [1]. It presents a diversity of transmission cycles that involve different species of parasites, vectors, and hosts in restricted ecological niches [2]. Thus, the indication of control measures must consider the entomological and epidemiological characteristics of each locality. According to Sabroza et al. [3], for each disease and particular situation there are environmental and behavioral factors related to the production of endemic or epidemic processes. To explain these factors, Sabroza et al. [3, page 216] used the concept of conditions receptivity, defined as the “set of environmental, social and behavioral characteristics that allow the reproduction of the parasites and its maintenance in the communities.” The city of Rio de Janeiro presents many areas where these conditions are met, mainly because of human occupation of hillsides, which modifies the landscape and favors the installation of ACL transmission cycles. The number of cases in the city has been increasing since the 1980s, with the west zone presenting the highest indices, more specifically the region of Jacarepaguá [4]. Most of the cases in the study area (Campus FIOCRUZ da Mata Atlantica - CFMA, Rio de Janeiro) are related to the occupation of hillsides in Maci?o da Pedra Branca, an Atlantic Forest area. The present study aimed to discuss an experience on ACL surveillance based on integrated tools related to entomological

Abstract: Background Highly active antiretroviral treatment (HAART) programs have been associated with declines in the burden of invasive pneumococcal disease (IPD) in industrialized countries. The aim of this study was to evaluate trends in IPD hospitalizations in HIV-infected adults in Soweto, South Africa, associated with up-scaling of the HAART program from 2003 to 2008. Methods Laboratory-confirmed IPD cases were identified from 2003 through 2008 through an existing surveillance program. The period 2003-04 was designated as the early-HAART era, 2005–06 as the intermediate-HAART era and 2007–08 as the established-HAART era. The incidence of IPD was compared between the early-HAART and established-HAART eras in HIV-infected and–uninfected individuals. Results A total of 2,567 IPD cases among individuals older than 18 years were reported from 2003 through 2008. Overall incidence of IPD (per 100,000) did not change during the study period in HIV-infected adults (207.4 cases in the early-HAART and 214.0 cases in the established-HAART era; p = 0.55). IPD incidence, actually increased 1.16-fold (95% CI: 1.01; 1.62) in HIV-infected females between the early-and established-HAART eras (212.1 cases and 246.2 cases, respectively; p = 0.03). The incidence of IPD remained unchanged in HIV-uninfected adults across the three time periods. Conclusion Despite a stable prevalence of HIV and the increased roll-out of HAART for treatment of AIDS patients in our setting, the burden of IPD has not decreased among HIV-infected adults. The study indicates a need for ongoing monitoring of disease and HAART program effectiveness to reduce opportunistic infections in African adults with HIV/AIDS, as well as the need to consider alternate strategies including pneumococcal conjugate vaccine immunization for the prevention of IPD in HIV-infected adults.

Cognitive dysfunction after critical illness: measurement, rehabilitation, and disclosure
Cheryl Misak
Critical Care , 2009, DOI: 10.1186/cc7962
Abstract: Intensivists are now examining cognitive outcomes after prolonged critical illness and advanced life support. The results are gripping – Hopkins and Brett [1] suggest that 'the neurocognitive impairments in ARDS [acute respiratory distress syndrome] survivors are long lasting and likely permanent'.I shall argue that it is difficult to pull apart the diverse factors that might prevent a patient's return to clear thinking. I shall also argue that disclosure of information about cognitive function, around which there is genuine uncertainty, may have a negative or self-fulfilling effect on patients' subsequent progress. Thus, important questions are raised about both the issue of disclosure of uncertain prognostic information and about just what interventions might be appropriate for those patients who are experiencing cognitive difficulties after being gravelly ill.In 1998 I spent weeks in an intensive care unit (ICU) with an invasive infection, severe ARDS, and an alarming number of organs in failure. I am also an academic philosopher and found much that was of genuine ethical and methodological interest in that first-hand experience. I shall draw on this experience in what follows, keeping alert to the danger of making unwarranted generalizations.Delirium is a frequent phenomenon in critically ill patient populations. Ely and coworkers [2] found that 18.5% of 275 mechanically ventilated patients had persistent coma, and of the remaining patients 81.7% developed delirium. Similar findings have been reported by other investigators [3-6]. The delirium tends to involve bizarre and terrifying nightmares, hallucinations, and paranoid delusions – often of the clinical staff trying to rape, murder, or otherwise harm the patient [7,8]. I have suggested that what makes ICU delirium especially insidious is that, unlike nightmares and more like paranoid delusions, it tends to occur in real time and hook onto slices of external reality [9,10]. One takes actual people in the ICU,

Abstract: Between-groups, randomized, after-onlyThere was no difference in response rates between the group that received International Postage Vouchers and the group that did not. (p = 0.23)International Postage Vouchers – "Coupon-Réponse International" have no effect on response rates for international postal surveys.Studies of interventions to increase response rates on self-administered, postal questionnaires have manipulated a variety of variables including elements of questionnaire design and presentation, sponsorship, pre-notification, postage, envelopes, incentives, rewards, and follow-up techniques. The systematic review by Edwards et al. [1] included 292 trials including 258,315 participants and 75 different strategies for increasing response to postal questionnaires. Various types of postage, on both out-going and return envelopes affected response rate. A search of the literature by Edwards et al. did not uncover any international postal questionnaire studies in which the respondents were provided with return postage in some form.We wanted to see if providing return postage to international respondents had an effect on response rate. International Postage Vouchers – "Coupon-Réponse International", which can be exchanged at the respondents' post office for stamps, was the only form of international return postage available in Norway. Although this is a cumbersome method of providing return postage, we wanted to see if eliminating postal costs that might be a barrier for some respondents would have an effect. In addition, we hypothesized that the gesture of providing the vouchers would serve as an incentive and it would be up to the individual how to use the vouchers, either for returning the questionnaire or to redeem stamps for personal use.The study population comprised journalists in the health field, broadly defined. Of the 100 journalists to whom paper questionnaires were sent, names and postal addresses of the first 62 on the convenience sample list were obta

Abstract: Trinidad and Tobago is one country consisting of two adjacent islands located just northeast of the Venezuelan coast with a combined area of 5070 km2 [1]. The human population of 1.25 million is multi-ethnic, multi-religious and multicultural and increases at 1% annually. In Trinidad, the major population centres are concentrated along the west coast and along an east-west transportation corridor in the north of the island [1].The multi-ethnic population of Trinidad and Tobago is reflected in its folk medicinal use. Previous research has indicated that the folk medicines used by hunters are derived from ancient Amerindian practices [2]. This paper will continue to explore the cultural origins of Caribbean folk medicine by investigating the contribution of the Chinese to Caribbean folk medicine. Chinese medicine has been described as a complex and holistic system of medical practice with its own philosophy, diagnosis, treatment systems and pharmacology which also includes acupuncture, moxibustion and Qi Gong. However in this paper I will focus on 'Ben Cao' (Herbalism) [3].The Chinese were the first Asian immigrants, arriving before the original East Indians who arrived in 1845. Chinese Tartars (192 men and one woman) were brought to Trinidad in the fall of 1806. These men from Macao, Penang and Canton were brought to cultivate tea but most were dissatisfied with local conditions and returned on the same ship [4,5]. The twenty-three who stayed made a living as entrepreneurs (butchers, shopkeepers, carpenters and market gardeners) and creolised (integrated into the local population).Prominent sugarcane planters believed that the emancipation of Caribbean slaves in 1838 would create a labour shortage. In the 1840s, the British "opened" a labor market of displaced or impoverished peasantry in southern China to fill this shortage and 2,500 mainly-male Chinese were brought legitimately to Trinidad as indentured workers, or were 'shanghaied' (abducted by European traders) [

Journal of Ethnobiology and Ethnomedicine , 2007, DOI: 10.1186/1746-4269-3-13
Abstract: Thirty respondents, ten of whom were male were interviewed from September 1996 to September 2000. The respondents were obtained by snowball sampling, and were found in thirteen different sites, 12 in Trinidad (Paramin, Talparo, Sangre Grande, Mayaro, Carapichaima, Kernahan, Newlands, Todd's Road, Arima, Guayaguayare, Santa Cruz, Port of Spain and Siparia) and one in Tobago (Mason Hall). Snowball sampling was used because there was no other means of identifying respondents and to cover the entire islands. The validation of the remedies was conducted with a non-experimental method.Plants are used for specific problems of both genders. Clusea rosea, Urena sinuata and Catharanthus roseus are used for unspecified male problems. Richeria grandis and Parinari campestris are used for erectile dysfunction.Ageratum conyzoides, Scoparia dulcis, Cucurbita pepo, Cucurbita maxima, Gomphrena globosa and Justicia pectoralis are used for prostate problems.The following plants are used for childbirth and infertility: Mimosa pudica, Ruta graveolens,Abelmoschus moschatus, Chamaesyce hirta, Cola nitida, Ambrosia cumanenesis, Pilea microphylla, Eryngium foetidum, Aristolochia rugosa, Aristolochia trilobata, Coleus aromaticus, Laportea aestuans and Vetiveria zizanioides.The following plants are used for menstrual pain and unspecified female complaints:Achyranthes indica, Artemisia absinthium, Brownea latifolia, Eleutherine bulbosa, Hibiscus rosa-sinensis, Eupatorium macrophyllum, Justicia secunda, Parthenium hysterophorus, Wedelia trilobata, Abelmoschus moschatus, Capraria biflora, Cordia curassavica, Croton gossypifolius, Entada polystachya, Leonotis nepetaefolia, Eryngium foetidum, Aristolochia rugosa, Aristolochia trilobata and Ambrosia cumanenesis.Native Caribbean plants have been less studied that those from Africa, India and Europe. Chamaesyce hirta has scientific support but as a diuretic. Other plants with level 3 validity for reproductive issues are: Achyranthes indica, Coleus ar
