Human Trafficking, Sex Tourism, and Child Exploitation on the Southern Border

Human trafficking and various other forms of child sexual exploitation on the United States-Mexico border are described from social science and law enforcement perspectives, including current laws and definitions, case examples, and descriptions of victims and traffickers. The Southern Border Initiative of the AMBER Alert Project is outlined as one effort to combat trafficking through collaboration between law enforcement agencies and programs in the United States and Mexico. Policy recommendations include increasing knowledge and collaboration between law enforcement, social service agencies, and judicial systems across the border region and between the United States and Mexico.

A binary engine fuelling HD 87643's complex circumstellar environment Determined using AMBER/VLTI imaging

Context. The star HD 87643, exhibiting the ""B[e] phenomenon"", has one of the most extreme infrared excesses for this object class. It harbours a large amount of both hot and cold dust, and is surrounded by an extended reflection nebula. Aims. One of our major goals was to investigate the presence of a companion in HD87643. In addition, the presence of close dusty material was tested through a combination of multi-wavelength high spatial resolution observations. Methods. We observed HD 87643 with high spatial resolution techniques, using the near-IR AMBER/VLTI interferometer with baselines ranging from 60 m to 130 m and the mid-IR MIDI/VLTI interferometer with baselines ranging from 25 m to 65 m. These observations are complemented by NACO/VLT adaptive-optics-corrected images in the K and L-bands, and ESO-2.2m optical Wide-Field Imager large-scale images in the B, V and R-bands. Results. We report the direct detection of a companion to HD 87643 by means of image synthesis using the AMBER/VLTI instrument. The presence of the companion is confirmed by the MIDI and NACO data, although with a lower confidence. The companion is separated by similar to 34 mas with a roughly north-south orientation. The period must be large (several tens of years) and hence the orbital parameters are not determined yet. Binarity with high eccentricity might be the key to interpreting the extreme characteristics of this system, namely a dusty circumstellar envelope around the primary, a compact dust nebulosity around the binary system and a complex extended nebula suggesting past violent ejections.

Surveillance of Rickettsia sp infection in capybaras (Hydrochoerus hydrochaeris) a potential model of epidemiological alert in endemic areas

Introduction. Capybaras (Hydrochoerus hydrochaeris) are considered amplifying hosts of Rickettsia sp. These rodents are usually parasitized by the tick vector, Amblyomma cajennense, the main vector of rickettsioses in humans and animals in South America. Capybaras can be used as sentinels in detection of circulation of rickettsiae. Objective. Antibodies to rickettsiae of spotted fever group were detected in capybaras in a rural area of Cordoba Province, northern Colombia. Materials and methods. Sera were analyzed from 36 capybaras in a rural area of Monteria (village of San Jeronimo) in Cordoba. For the detection of IgG antibodies, indirect immunofluorescence was performed. The antigens were derived from R. rickettsia strain Taiacu isolated in Brazil. Capybara sera were diluted 1:64 for IFA analysis. Ticks were collected from each capybara (also known as chiguiro) and identified to species. Results. The seroprevalence of spotted fever group Rickettsia was 22% (8 capybaras). Four sera had a titer of 1:64, 3 had a titer of 1:128 and one serum had a titer of 1:512. All ticks removed from the capybaras (n=933) were taxonomically identified as Amblyomma cajennense. Conclusion. Colombia has areas endemic for rickettsioses, as indicated by confirmed annual outbreaks. The current study reports the first evidence of natural rickettsial infection of the spotted fever group in capybaras from Colombia. The findings suggest that capybaras can be used as sentinels for the circulation of rickettsiae and can identify endemic areas for the transmission of rickettsial diseases.

National alert campaign about increased cholesterol: determination of cholesterol levels in 81,262 Brazilians

OBJECTIVE: To determine the levels of total cholesterol in a significant sample of the Brazilian population. METHODS: Blood cholesterol was determined in 81.262 individuals > 18 years old (51% male, 44.7 ± 15.7 years), using Accutrend equipment, in the cities São Paulo, Campinas, Campos do Jordão, São José dos Campos, Santos, Santo André, Ribeirão Preto, Porto Alegre, Rio de Janeiro, Belo Horizonte, Curitiba, Brasília, Salvador and documented in the presence of other risk factors (RF) for coronary artery disease (CAD) (systemic hypertension, CAD in the family, smoking, and diabetes). Participants were classified according to sex, age, and the presence or absence of RF, respectively, as 0 RF, 1 RF and > 2 RF. The percentage of individuals with cholesterol > 200 mg/dL and > 240 mg/dL was evaluated. RESULTS: The prevalence of individuals with 0, 1, and > 2 risk factors was 30% (n = 24,589), 36% (n =29,324), and 34% (n = 27,349) respectively, (P=0.657), and the mean total cholesterol of the population was 199.0 ± 35.0 mg/dL. Cholesterol levels above 200 and 240 mg/dL were found, respectively, in 40% (n = 32,515) and 13% (10.942) of individuals. The greater the number of risk factors the higher the levels of cholesterol (P<0.0001) and the greater the proportion of individuals with cholesterol > 200 mg/dL (P=0.032). No difference existed in the proportion of individuals with cholesterol > 240 mg/dL (P=0.11). CONCLUSION: A great percentage of individuals with cholesterol levels above those recommended to prevent coronary artery disease was found.

Description of Pintomyia (Pifanomyia) falcaorum sp. n. (Diptera: Psychodidae: Phlebotominae), a Fossil Sand Fly from Dominican Amber

A new species of sand fly, Pintomyia (Pifanomyia) falcaorum is described from an amber originated from the northern mountain range of Dominican Republic. The male sand fly specimen is well preserved and most features used in Phlebotominae taxonomy are seen with remarkable clarity.

Acute schistosomiasis outbreak in the metropolitan area of Belo Horizonte, Minas Gerais: alert about the risk of unnoticed transmission increased by growing rural tourism

The present article describes the occurrence of 17 cases of acute schistosomiasis in the metropolitan area of Belo Horizonte, state of Minas Gerais, Brazil. All individuals affected took a bath in a swimming pool of a holiday resort that was provided with water from a nearby brook. The apparently clean water and the absence of snails in the pool gave the wrong impression that there was no risk for infection. During a malacological survey at the site snails of the species Biomphalaria glabrata were found and tested positive for Schistosoma mansoni. All the patients live in the middle-class area of Barreiro, metropolitan area of Belo Horizonte and have medium grade school education. The difficulties in establishing the right diagnosis is expressed by the search for medical attention in 17 different medical facilities, the wide range of laboratory test and the inadequate treatment administration. A lack of knowledge about the disease was found in all groups studied. The booming rural tourism in endemic areas is identified as a probable risk factor for infection, especially for individuals of the non-immune middle and upper class parts of the society in urban centers. Special attention is given to a multidisciplinary approach to the complex issue of disease control and prevention.

Pintomyia (Pifanomyia) paleotownsendi, a new sand fly from the Miocene amber of Dominican Republic (Diptera: Psychodidae: Phlebotominae)

Phlebotominae includes some vector species, mainly that of leishmaniases, with a very old host-parasite relationship. Some species fossils of this subfamily have been recently described and this paper presents the description of a new sand fly Pintomyia (Pifanomyia) paleotownsendi sp. nov in amber. The gonostyle present four spines, being one apical, one external superior implanted close to the apical third, one external inferior in the middle of the structure and one internal implanted in the basal third. This disposition of the spines may separate the new species from others in the sub genus.

Early Cretaceous trypanosomatids associated with fossil sand fly larvae in Burmese amber

Early Cretaceous flagellates with characters typical of trypanosomatids were found in the gut of sand fly larvae, as well as in surrounding debris, in Burmese amber. This discovery supports a hypothesis in which free-living trypanosomatids could have been acquired by sand fly larvae in their feeding environment and then carried transtadially into the adult stage. At some point in time, specific genera were introduced into vertebrates, thus establishing a dixenous life cycle.

Developing new approaches for detecting and preventing Aedes aegypti population outbreaks: basis for surveillance, alert and control system

A new approach to dengue vector surveillance based on permanent egg-collection using a modified ovitrap and Bacillus thuringiensis israelensis(Bti) was evaluated in different urban landscapes in Recife, Northeast Brazil. From April 2004 to April 2005, 13 egg-collection cycles of four weeks were carried out. Geo-referenced ovitraps containing grass infusion, Bti and three paddles were placed at fixed sampling stations distributed over five selected sites. Continuous egg-collections yielded more than four million eggs laid into 464 sentinel-ovitraps over one year. The overall positive ovitrap index was 98.5% (over 5,616 trap observations). The egg density index ranged from 100 to 2,500 eggs per trap-cycle, indicating a wide spread and high density of Aedes aegypti (Diptera: Culicidae) breeding populations in all sites. Fluctuations in population density over time were observed, particularly a marked increase from January on, or later, according to site. Massive egg-collection carried out at one of the sites prevented such a population outbreak. At intra-site level, egg counts made it possible to identify spots where the vector population is consistently concentrated over the time, pinpointing areas that should be considered high priority for control activities. The results indicate that these could be promising strategies for detecting and preventing Ae. aegypti population outbreaks.

Creació d'una discoteca: Amber Club

El món de l’oci nocturn és un món que molta gent disfruta però que ningú acaba de conèixer. Tothom sap per on van els trets principals, però ningú es preocupa profundament per saber realment com funciona, quins són els costos, si els beneficis són elevats, o si és difícil aconseguir que un negoci sigui viable. Aquest, doncs, ha estat el pilar sobre del qual s'ha construït el nostre treball.A través de la creació d’una discoteca i el seu anàlisi cost-benefici hem intentat esbrinar quina és la viabilitat d’un projecte d’aquestes característiques, analitzant tots els costs que s’han d’incórrer, i realitzant un supòsit a la baixa dels ingressos que s’obtindrien.Per dur a terme aquest anàlisi hem realitzat 200 enquestes repartides per les diferents universitats de la província de Barcelona. D’aquesta manera hem pogut analitzar si hi ha demanda per una nova discoteca i quines són les preferències del consumidor.Una vegada fet aquest anàlisi, hem procedit a la recerca d'un local que s'adapti a les nostres necessitats i a les mostrades pel públic enquestat. Al no voler entretenir-nos en qüestions com la decoració del local, o l’adaptació d’aquest a tota la normativa vigent, hem partit del supòsit que un local que actualment funciona estigués disponible pel lloguer, concretament Opium Mar. Hem introduït un seguit de reformes que creiem necessàries pel millor funcionament, i a continuació hem començat amb les estratègies de màrqueting i la determinació dels serveis oferts.Dos punts seran claus per tal que la discoteca funcioni correctament. Primer de tot, el fet que sigui coneguda per un gran públic, i llavors que aquest públic en qüestió estigui content amb el serveis oferts. És per això que hem destinat un gran nombre de recursos en màrqueting (pàgina web, mailing , SMS...) i ens hem centrat també amb tots els serveis que podem oferir (guarda-roba, sales VIP...). La reputació, ens han dit molts responsables, pot ser l’eina que pot fer del teu projecte una gran font d’ingressos, o el contrari, una gran pèrdua de diners.També ens hem centrat en el personal i el subministrament de begudes, calculant així quin és el nombre de treballadors necessaris per tirar endavant el projecte, i quin és l’estoc de begudes òptim que hem de tenir per cobrir tota la demanda.Finalment, hem tingut en compte els impostos que hem d'incórrer a un projecte d'aquest tipus, ja sigui impost de societats, el cost de la llicència per exercir l'activitat, IVA, etc.Una conclusió és clara després de la realització d’aquest projecte: la nostra discoteca és rendible, i per extensió qualsevol altre amb un nombre considerable d’assistència. El valor afegit que crea un projecte d’aquestes magnituds és tan gran, i la despesa mitjana de la gent en oci nocturn tan considerable, que un projecte capaç de portar un nombre de clients relativament petit en funció del local, pot presentar beneficis
