The present study carried out in the context of the Baseline Studies of the PROESF was aimed at evaluating the impact of the Family Health Program (PSF) on indicators for child health in cities with more than 100,000 inhabitants in the Brazilian Northeast. Four cities were investigated. In each one, twenty censual sectors were selected randomly from areas covered by the PSF and compared with twenty sectors selected from areas not covered by the PSF on the basis of socioeconomic criteria. In most cases, no significant differences were found between the areas covered and not covered by the PSF. The only difference found was a significantly lower rate of hospital admissions due to diarrhea but this was on account of the Program of Community Health Agents. The PSF exerted no additional effect on the reduction of this indicator. It was also observed that the way by which the program is implemented in each city interferes directly in the results. Thus, there is no basis for considering the PSF per se ineffective or not differing from other programs with regard to its health care patterns. An evaluation of the PSF would necessarily have to include an analysis of the way the program is implemented and conducted in each case, besides considering its general socioeconomical and political characteristics.

This paper uses a difference in difference model to investigate the impact of a large scale and high mortality 2005 earthquake in Pakistan on women’s fertility decisions and children’s health outcomes. Using a nationally representative, cross sectional DHS data from 2006 and geographical data from USGS, this paper investigates how variation in earthquake intensity levels can differentially impact total fertility for women and the likelihood of children suffering from diseases such as diarrhea, Acute Respiratory Infections (ARI) and fever. The post-earthquake results demonstrate a statistically significant increase in total fertility for areas closer to the epicenter of the earthquake, within a 100km radius of the rupture surface and at higher altitudes. Similarly, for children who were in-utero at the time of the earthquake, the probability of having early symptoms of ARI or fever was much smaller in lower earthquake intensity zones compared to the highest intensity zone.

BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) is a globally prevalent cause of diarrhea. Though usually self-limited, it can be severe and debilitating. Little is known about the host transcriptional response to infection. We report the first gene expression analysis of the human host response to experimental challenge with ETEC. METHODS: We challenged 30 healthy adults with an unattenuated ETEC strain, and collected serial blood samples shortly after inoculation and daily for 8 days. We performed gene expression analysis on whole peripheral blood RNA samples from subjects in whom severe symptoms developed (n = 6) and a subset of those who remained asymptomatic (n = 6) despite shedding. RESULTS: Compared with baseline, symptomatic subjects demonstrated significantly different expression of 406 genes highlighting increased immune response and decreased protein synthesis. Compared with asymptomatic subjects, symptomatic subjects differentially expressed 254 genes primarily associated with immune response. This comparison also revealed 29 genes differentially expressed between groups at baseline, suggesting innate resilience to infection. Drug repositioning analysis identified several drug classes with potential utility in augmenting immune response or mitigating symptoms. CONCLUSIONS: There are statistically significant and biologically plausible differences in host gene expression induced by ETEC infection. Differential baseline expression of some genes may indicate resilience to infection.

The Early Miocene Napak XV locality (ca 20.5 Ma), Uganda, has yielded an interesting assemblage of fossils, including the very well represented amphicyonid Hecubides euryodon. The remarkable find of a nearly complete mandible, unfortunately with poorly preserved dentition, together with new dental remains allow us to obtain a better idea about the morphology and variability of this species. Additionally, we describe a newly discovered mandible of Hecubides euryodon from the Grillental-VI locality (Sperrgebiet, Namibia), which is the most complete and diagnostic Amphicyonidae material found in this area. Comparisons with Cynelos lemanensis from Saint Gérand le Pouy (France), the type locality, and with an updated sample of the species of amphicyonids described in Africa leads us to validate the genus Hecubides. Hecubides would be phylogenetically related to the medium and large size species of Amphicyonidae from Africa, most of them now grouped into the genera Afrocyon and Myacyon, both endemic to this continent.

The aim of this study was to determine the haematological value and biochemical blood in baby alpacas with enteric disorder. A total of 30 blood and serum samples were collected from alpacas of 1 month old with diarrhoea and 5 blood samples of clinically healthy baby alpacas (controls). The animals were from communities in the central Andes from Peru. About haematology were determined haematocrit, haemoglobin concentration, red blood count and white blood count that were not significantly different between control animals and animals with diarrhoea. Moreover, biochemical blood parameters as total protein, albumin and calcium decrease significantly (p<0.05). We conclude that our results could be considered as factors in the mortality of baby alpaca by infectious diarrhoea.

La llegada de forasteros a nuestro país no era una empresa fácil de acometer en una España en crisis después de 1898, dividida políticamente entre conservadores y liberales, y con serias carencias en sus infraestructuras y transportes. La actividad comercial española necesitaba nuevos frentes y el turismo podría convertirse en un importante factor y motor mercantil.La búsqueda y la construcción en torno a ese objetivo comenzó a partir de 1905, cuando la iniciativa pública y privada realizaron las primeras gestiones encaminadas a este fin, y se constituyen se constituyeron sociedades-sindicatos, según el modelo francés, para fomentar la afición por los viajes y la recepción de viajeros.

PURPOSE: To evaluate the addition of cetuximab to neoadjuvant chemotherapy before chemoradiotherapy in high-risk rectal cancer. PATIENTS AND METHODS: Patients with operable magnetic resonance imaging-defined high-risk rectal cancer received four cycles of capecitabine/oxaliplatin (CAPOX) followed by capecitabine chemoradiotherapy, surgery, and adjuvant CAPOX (four cycles) or the same regimen plus weekly cetuximab (CAPOX+C). The primary end point was complete response (CR; pathologic CR or, in patients not undergoing surgery, radiologic CR) in patients with KRAS/BRAF wild-type tumors. Secondary end points were radiologic response (RR), progression-free survival (PFS), overall survival (OS), and safety in the wild-type and overall populations and a molecular biomarker analysis. RESULTS: One hundred sixty-five eligible patients were randomly assigned. Ninety (60%) of 149 assessable tumors were KRAS or BRAF wild type (CAPOX, n = 44; CAPOX+C, n = 46), and in these patients, the addition of cetuximab did not improve the primary end point of CR (9% v 11%, respectively; P = 1.0; odds ratio, 1.22) or PFS (hazard ratio [HR], 0.65; P = .363). Cetuximab significantly improved RR (CAPOX v CAPOX+C: after chemotherapy, 51% v 71%, respectively; P = .038; after chemoradiation, 75% v 93%, respectively; P = .028) and OS (HR, 0.27; P = .034). Skin toxicity and diarrhea were more frequent in the CAPOX+C arm. CONCLUSION: Cetuximab led to a significant increase in RR and OS in patients with KRAS/BRAF wild-type rectal cancer, but the primary end point of improved CR was not met.

An exploratory phase II biomarker-embedded trial (LPT109747; NCT00526669) designed to determine the association of lapatinib-induced fluoropyrimidine gene changes with efficacy of lapatinib plus capecitabine as first-line treatment for advanced gastric cancer or gastroesophageal junction adenocarcinoma independent of tumor HER2 status. Tumor biopsies obtained before and after 7-day lapatinib (1,250 mg) to analyze changes in gene expression, followed by a 14-day course of capecitabine (1,000 mg/m(2) twice daily, 14/21 days) plus lapatinib 1,250 mg daily. Blood samples were acquired for pharmacokinetic analysis. Primary clinical objectives were response rate (RR) and 5-month progression-free survival (PFS). Secondary objectives were overall survival (OS), PFS, time to response, duration of response, toxicity, and identification of associations between lapatinib pharmacokinetics and biomarker endpoints. Primary biomarker objectives were modulation of 5-FU-pathway genes by lapatinib, effects of germline SNPs on treatment outcome, and trough steady-state plasma lapatinib concentrations. Sixty-eight patients were enrolled; (75% gastric cancer, 25% gastroesophageal junction). Twelve patients (17.9%) had confirmed partial response, 31 (46.3%) had stable disease, and 16 (23.9%) had progressive disease. Median PFS and OS were 3.3 and 6.3 months, respectively. Frequent adverse events included diarrhea (45%), decreased appetite (39%), nausea (36%), and fatigue (36%). Lapatinib induced no changes in gene expression from baseline and no significant associations were found for SNPs analyzed. Elevated baseline HER3 mRNA expression was associated with a higher RR (33% vs. 0%; P = 0.008). Lapatinib plus capecitabine was well tolerated, demonstrating modest antitumor activity in patients with advanced gastric cancer. The association of elevated HER3 and RR warrants further investigation as an important player for HER-targeted regimens in combination with capecitabine

The total traveling with different types of transportation has increased drastically since the 50´s. Despite this increase, the use of the public transportation has decreased in percentage which has its explanation in the overall increased use of cars as transportation. Many researchers believes that better traffic information in the public transport can lead to increased use. Therefore this study aims to investigate how mobile personalized real-time information can increase customer satisfaction in the public transport in order to maintain and attract more travelers. The study addresses the problem through a case study at the Swedish transit agency Tågkompaniet, where customers and staff are studied in order to map the present situation regarding information in the public transport. The case study also sets out to investigate which type of real-time information that is considered to be most important for the travelers. At last the study also investigate which types of technical solutions that is needed, and how the needs of travelers can be considered to be able to offer mobile personalized real-time information. The findings are that there is a dissatisfaction regarding the transit information among both travelers and staff, and that their needs and demands must be met to a greater extent in order to increase the customer satisfaction. Furthermore, the findings are also that information attributes regarding delays and disruptions in the public transport is considered to be most important by travelers. Functions such as subscribe to information, push notifications and information associated with the transit ticket are necessary to be able to provide travelers with mobile personalized real-time information. Lastly the study provides a tool to consider traveler needs in development and evaluation of mobile personalized information systems within the public transport.

Chronic weight loss in marmosets is often associated with wasting marmoset syndrome (WMS), an important disease that occurs in callitrichid colonies around the world. Even though its etiology is very difficult to determine, particular variables, such as weight loss, diarrhea and alopecia, associated or not with infestation in the pancreatic ducts with Trichospirura leptossoma (Nematoda: Thelazioidea), seem to be linked with the syndrome. This study investigated the histopathology of the lungs, duodenum, liver, gallbladder, extrahepatic bile ducts and pancreatic ducts of six common marmosets (Callithrix jacchus) suffering from severe non-diarrheic weight loss. Three individuals died naturally and the other three were euthanized. Microscopic findings showed the presence of adult flukes (Platynosomum) in the liver. These flukes, which provoke common infection in cats, were also observed inside the gallbladder as well as in the intra and extrahepatic bile ducts in common marmosets. Portal fibrosis was observed in two animals, which developed chronic fibrosing hepatopathy (biliary pattern, grade 3). The disease progresses without diarrhea and without pancreatic lesions or infestation. With the rogression, the animals presented with ascending cholangitis, cholestasis and portal fibrosis, sometimes culminating in secondary biliary cirrhosis. Therefore, this nfirmity, associated with chronic weight loss in common marmosets, could be another tiological factor linked with WMS

When booking a trip along the railway through several train operators it is not uncommon that information about possible disruptions along the railway (that can change or cancel the booked trip) are not relayed to the passengers. Today, research on rail traffic in Sweden is limited. It is unclear how satisfied customers are with the quality of the information they receive during their trip (if they get it at all), including with respect to disruptions. Our partners have identified what they believe is a need among train operators, which is a service for disruption information to travelers. In addition to confirming that there is a need for such a service, we have an interest to investigate how such a service might look like and what the users want. Our research has shown that passengers are not satisfied with either the amount of information about disturbances or how often they get it. Along with KnowitBorlänge, we have come up with a proposed solution that uses already existing technologies to create a portal for an efficient way to get the interference information to travelers.

Purpose - To examine the leisure cruise service environment—the shipscape—and its effects on cruisers’ emotions, meaning-making, and onboard behavior. Design/methodology/approach - This paper uses qualitative data from 260 cruise customers that was mined from archived online discussion boards. Data were analyzed based on grounded theory and interpretive methods to derive an understanding of shipscape meanings and influences from the cruiser’s perspective. Research limitations/implications - Given the exploratory research objective and interpretive methodology, generalizability beyond the cruise context is limited. However, research findings suggest not only that ambient shipscape conditions influence cruisers’ pleasure, but also that ship layout, décor, size, facilities, and social factors influence the meanings cruisers attach to cruise brands and to the overall cruise experience. Originality/value - This paper explores atmospheric effects on consumer behavior in a context as yet examined by tourism and hospitality scholars. The findings extend Bitner’s (1992) servicescape framework and reveal novel atmospheric and social effects that influence cruise travelers’ experience.

Known as one of North America’s natural treasures, the Loess Hills is also one of our country’s archaeological gems. This unique landscape harbors hundreds of well-preserved earth lodge dwellings and palisades villages built by ancestral Plains Indians. The descendants of these early Iowa farmers were first described in the journals and accounts of 18th- and 19th-century travelers and explorers. Celebrated artists, such as Karl Bodmer and George Catlin, forever fixed the vibrant life ways of these people in our mind’s eye. The historical legacy of the Loess Hills lies in a rich archaeological record.
