Occurrence of Aliarcobacter spp. in fresh and pre-cut vegetables of common use in San José, Costa Rica.

Aliarcobacter is a Gram-negative rod that can cause disease in both animals and humans. Several studies have evidenced its presence in a wide variety of foods. Given that the number of foodborne illness outbreaks linked to the consumption of vegetables has increased worldwide and that there is a lack of information about the occurrence of Aliarcobacter spp. in these, the aim of this study was to evaluate its presence and the occurrence of virulence factors in both fresh and ready-to-eat vegetable samples. 180 vegetable samples from Costa Rica were analyzed for the presence of Aliarcobacter spp., including 90 pre-cut vegetable packages and 90 fresh vegetables. Two (2.2%) of the isolates from pre-cut vegetables and 19 (21.1%) of the isolates obtained from fresh vegetables were confirmed as Aliarcobacter spp. One of the isolates from the pre-cut vegetable samples was identified as A. butzleri. For the fresh vegetables, 11 isolates were identified as A. skirrowii, one as A. butzleri, and the 7 remaining isolates could not be identified at a species level. There is an 87.5% positivity for hecA and 93.8% for pldA, virulence genes in strains isolated from fresh produce, contrasting with an absolute absence from pre-cut vegetable-isolated strains. These results evidence the presence of Aliarcobacter on fresh and pre-cut vegetables from Costa Rica and the potential hazard it might represent for public health.

Presence of Listeria monocytogenes in Ready-to-Eat Meat Products Sold at Retail Stores in Costa Rica and Analysis of Contributing Factors.

ABSTRACT: Listeria monocytogenes is a pathogenic bacterium associated with ready-to-eat (RTE) meat products sold at the retail level. The objective of this research was to determine the prevalence of L. monocytogenes in RTE meat products sold at retail in Costa Rica and to study the factors associated with the levels of contamination; analyzed factors include hygienic practices within stores (cutting techniques and microbial contamination of products) and the behavior of the isolates (persistence against antimicrobials and transfer potential). A total of 190 samples of RTE meat products were collected and analyzed for the presence of coliforms and Listeria spp. Isolates of L. monocytogenes were then evaluated in terms of resistance to disinfectants (quaternary ammonium compound [QAC] and chlorine) and their transfer potential from food contact surfaces (knife and cutting boards). Overall Listeria spp. prevalence was 37.4% (71 of 190); Listeria innocua was present in 32.1% (61 of 190) of the products, and L. monocytogenes was found in just 2.6% (5 of 190) of the samples. Most contaminated samples were cut with a knife at the moment of purchase (44.2%). When analyzing practices within the stores, it was observed that L. monocytogenes transfer from inoculated knife to salchichón was higher for samples cut at the beginning of the experiment. In addition, L. monocytogenes transfer from inoculated cutting boards was independent of the number of slices but contamination from plastic was higher than wood. Regarding L. monocytogenes resistance to disinfectants, average reductions of 2.6 ± 1.1 log CFU/mL were detected after 6 min of exposure to 200 ppm of chlorine; however, chlorine resistance varied among the strains. Prevalence of L. monocytogenes in RTE meat products sold at retail could be associated with handling practices within the stores; further studies are necessary to estimate the impact of these practices on the overall risk for consumers.

C677T and A1298C methylenetetrahydrofolate reductase polymorphisms and breast cancer susceptibility among Latinos: a meta-analysis.

BACKGROUND: Previous meta-analyses have shown an ethnic dependency of the C677T and the A1298C methylenetetrahydrofolate reductase (MTHFR) polymorphisms, with no focus on the Latino population. For Latinos, many studies have examined these polymorphisms and breast cancer susceptibility, yielding no concise result. Therefore, we undertook this meta-analysis to determine the effect these polymorphisms have on breast cancer risk for Latinos. METHODS: PubMed, EBSCO, LILACS, Scopus, and Latin American-specific databases were searched for studies exploring the association between the MTHFR polymorphisms and breast cancer susceptibility in Latinos until January 2019. Genotype distributions were extracted and, depending on the level heterogeneity determined by the ψ2-based Q test and the I2 test, fixed-effects or random-effects models were used to calculate pooled odds ratios (ORs) with 95% confidence intervals (95% CIs) for the heterozygous, homozygous, dominant, recessive, and allelic genetic models. No publication bias was detected by the Begg-Mazumdar's test and Egger's test. RESULTS: Of the 280 retrieved publications, 9 studies were included: 9 for the C677T polymorphism and 5 for the A1298C polymorphism. For the C677T polymorphism, there was an elevated risk for the homozygous (OR 1.42, 95% CI 1.05-1.92), the dominant (OR 1.16, 95% CI 1.02-1.31), the recessive (OR 1.33, 95% CI 1.01-1.75), and the allelic model (OR 1.17, 95% CI 1.03-1.33, p < 0.01). No association between the A1298C polymorphism and the risk to develop breast cancer was determined. CONCLUSION: The results indicated that, for Latinos, the C677T polymorphism is associated with a significant risk for developing breast cancer, whereas the A1289C polymorphism does not.

Simultaneous removal of structurally different pesticides in a biomixture: Detoxification and effect of oxytetracycline.

The biopurification systems (BPS) used for the treatment of pesticide-containing wastewater must present a versatile degrading ability, in order to remove different active ingredients according to the crop protection programs. This work aimed to assay the simultaneous removal of several pesticides (combinations of herbicides/insecticides/fungicides, or insecticides/fungicides) in a biomixture used in a BPS over a period of 115 d, and in the presence of oxytetracycline (OTC), an antibiotic of agricultural use that could be present in wastewater from agricultural pesticide application practices. The biomixture was able to mostly remove the herbicides during the treatment (removal rates: atrazine ≈ linuron > ametryn), and suffered no inhibition by OTC (only slightly for ametryn). Two fungicides (carbendazim and metalaxyl) were removed, nonetheless, in the systems containing only fungicides and insecticides, a clear increase in their half-lives was obtained in the treatments containing OTC. The neonicotinoid insecticides (imidacloprid and thiamethoxam) and the triazole fungicides (tebuconazole and triadimenol) were not significantly eliminated in the biomixture. Globally, the total removal of active ingredients ranged from 40.9% to 61.2% depending on the system, following the pattern: herbicides > fungicides > insecticides. The ecotoxicological analysis of the process revealed no detoxification towards the microcrustacean Daphnia magna, but a significant decay in the phytotoxicity towards Lactuca sativa in some cases, according to seed germination tests; in this case, OTC proved to be partially responsible for the phytotoxicity. The patterns of pesticide removal and detoxification provide inputs for the improvement of BPS use and their relevance as devices for wastewater treatment according to specific pesticide application programs.

Effects of oxytetracycline on the performance and activity of biomixtures: Removal of herbicides and mineralization of chlorpyrifos.

Biopurification systems (BPS) are design to remove pesticides from agricultural wastewater. This work assays for the first time the potential effect of an antibiotic of agricultural use (oxytetracycline, OTC) on the performance of a biomixture (biologically active core of BPS), considering that antibiotic-containing wastewaters are also produced in agricultural labors. The respiration of the biomixture was stimulated in the presence of increasing doses of OTC (≥100mgkg-1), and only slightly increased with lower doses (≤10mgkg-1). When co-applied during the removal of chlorpyrifos, OTC increased chlorpyrifos mineralization rates at low doses, resembling a hormetic effect. The biomixture was also able to remove three herbicides (atrazine, ametryn and linuron) with half-lives of 24.3 d, 43.9 d and 30.7 d; during co-application of OTC at a biomixture-relevant concentration, only the removal of ametryn was significantly inhibited, increasing its half-life to 92.4 d. Ecotoxicological assays revealed that detoxification takes place in the biomixture during the removal of herbicides in the presence of OTC. Overall results suggest that co-application of OTC in a biomixture does not negatively affect the performance of the matrix in every case; moreover, the co-application of this antibiotic could improve the mineralization of some pesticides.

Impact of a pharmacotherapy plan to improve adherence for patients with type-2 diabetes and hypertension in a Chilean hospital.

BACKGROUND: Non-adherence to prescribed treatment is a principle cause of treatment failure in patients with chronic diseases, such as type 2 diabetes mellitus (T2DM) and hypertension. Improved patient monitoring and education have been shown to improve adherence and clinical outcomes. OBJECTIVE: This study evaluates the impact of a pharmacotherapy optimization plan centered on patient education that was implemented at a hospital in Arauco, Chile. METHODS: A prospective study was conducted using 50 randomly selected patients diagnosed with both T2DM and hypertension. Each patient participated in three successive interview sessions over 6 months. At each session, the following variables were evaluated by a pharmacist: blood pressure, HbA1c, adherence to prescribed medication, and patient knowledge of disease. RESULTS: Significant decreases were observed for HbA1c (<0.001), and SBP (<0.001), with stronger and more significant decreases observed for females. Patient adherence to prescribed medication also improved, but not significantly. The number of patients with full knowledge of their diseases increased significantly (p < 0.001) from 10 to 66%. CONCLUSION: This study suggests that the incorporation of a pharmacotherapeutic optimization plan for patients with chronic diseases can have a positive impact on the control of chronic diseases, such as T2DM and hypertension.

Effect of artificial feeders on pollen loads of the hummingbirds of Cerro de la Muerte, Costa Rica.

Although sugar-water feeders are commonly used by enthusiasts to attract hummingbirds, little is known about how they affect hummingbird behavior and flower use. We studied the highland hummingbird assemblage of Cerro de La Muerte, Costa Rica, both at a site with permanent feeders (La Georgina Restaurant) and further from it. We examined how feeder use and monopolization affected seasonal changes in pollen loads during four sampling periods, including dry and wet seasons, from 2003-2005. We expected that species monopolizing the feeders would carry little or no pollen whatsoever, and would have pollen loads characterized by low floral diversity, in contrast with species less dependent on feeders. We obtained pollen samples from 183 individuals of four hummingbird species captured around the feeders using mist nets, which were compared with a pollen reference collection of plants with a pollination syndrome by hummingbirds. The same methods were implemented at a site 3km away from the feeders. Feeder usage was quantified by counting the number of times hummingbirds drank from the feeders in periods of 4min separated by 1min. The effects of hummingbird species and season on pollen load categories were assessed using a nominal logistic regression. The alpha species at the site, the Fiery-throated Hummingbird (Panterpe insignis), dominated the feeders during the dry season. Meanwhile, in the wet season, feeder usage was more evenly distributed across species, with the exception of the Volcano Hummingbird, Selasphorus flammula, which occupies the last place in the dominance hierarchy. Pollen loads of hummingbirds captured near feeders were low in abundance (more than 50% of captured individuals had zero or low pollen loads), and low in species richness (96% of the hummingbirds with pollen from only one plant genus, Centropogon). Overall pollen loads increased during the dry season coinciding with peaks in flower availability, although the majority of captured hummingbirds carried no pollen. Mist nets located 3km from La Georgina returned few captures (one-to-three specimens) per sampling date, contrasting with observations made before feeders were present. These results suggest that sugar-water feeders gather hummingbirds in over considerable distances drawing them away from flowers. The competitive and antagonistic pattern shown between feeders and flowers indicate that natural pollination system could be significantly altered. Supplementing hummingbirds with food seems likely to interfere with pollination networks already stressed by many anthropogenic effects.

El uso de comederos constituye una práctica común para atraer colibríes, a pesar de que sabemos poco acerca de sus efectos sobre las relaciones ecológicas entre colibríes y sus plantas asociadas. Estudiamos el grupo de colibríes del Cerro de La Muerte, Costa Rica, en un sitio con comederos permanentes (Restaurante La Georgina), así como en un lugar alejado de los comederos. Analizamos cómo el uso y monipolización estacional de los comederos afectaba la carga de polen en cuatro períodos de muestreo entre 2003 y 2005. Esperábamos que las especies que monopolizaban los comederos tuvieran poco o cero polen, y si lo presentaban que la carga de polen estuviera representada por pocas especies en comparación con especies menos dependientes de los comederos. En la estación seca, la especie alfa Panterpe insignis, dominó los comederos. En la estación lluviosa el uso de comederos fue más equitativo. La carga de polen fue muy baja en abundancia (50% de los colibríes tenían poco o cero polen) y diversidad (96% de los colibríes tenían polen solamente del género Centropogon). Encontramos una relación competitiva y antagonística entre la visitación de comederos y la abundancia de flores. La carga de polen aumentó en la estación seca al haber más flores, aunque la mayoría de los colibríes capturados no tenían polen. Durante la estación lluviosa, cuando hay menos flores disponibles, el uso de comederos aumenta y la carga de polen disminuye. El uso de comederos interfiere en redes de polinización y se combina con otros efectos antropológicos negativos, tales como el calentamiento global, fragmentación de hábitats, cambio en el uso del suelo, que hacen más difícil la conservación de complejas redes tróficas.

[Blood supply during disasters: the experience of Chile in 2010]. / Abastecimiento de sangre durante desastres: la experiencia de Chile en 2010.

A review of the management of blood supply and its administration during disasters was conducted based on the experience of several events that occurred primarily from 2000-2010, particularly the earthquake that measured 8.8 on the Richter scale that struck central and southern Chile on 27 February 2010. The objective was to provide information that could be useful in improving response plans and strategies during potential future disasters. The descriptive information on response procedures was obtained from interviews, internal reports, and the computer database from the Maule regional blood production center. The results lead to the conclusion that to respond efficiently and effectively to the need for blood in the immediate wake of a disaster it is essential to have both a centralized management system that facilitates the supply and administration of blood and volunteers with competence in health that are willing to swiftly arrive during these events. A change in the profile of blood donors during such emergencies was also observed. In Chile, for example, during the two weeks after the earthquake, the ratio of male/female donors was reversed. There was 61.1% participation by women, whereas in the week before the event women accounted for only 37%.

Abastecimiento de sangre durante desastres: la experiencia de Chile en 2010 / Blood supply during disasters: the experience of Chile in 2010

Se realizó una revisión de la gestión del abastecimiento y suministro de sangre durante desastres a partir de las experiencias de diversos eventos ocurridos principalmente en la primera década de este siglo, y en particular el terremoto grado 8,8 en la escala de Richter que afectó la zona centro sur de Chile el 27 de febrero de 2010. El objetivo fue proporcionar información que pueda ser útil para mejorar las estrategias y planes de respuesta durante potenciales desastres futuros. La información descriptiva sobre los procedimientos de respuesta se obtuvo mediante entre-vistas, reportes internos y la base de datos del sistema informático del Centro Productivo Regional de Sangre del Maule. Los resultados permiten concluir que para responder de manera eficiente y efectiva a las necesidades de sangre inmediatamente después de un desastre es de importancia clave tener un sistema centralizado de gestión que facilite el abastecimiento y el suministro de sangre y con-tar con personal voluntario competente en salud que esté dispuesto a acudir con celeridad durante estos eventos. Asimismo, se ha observado que durante dichas emergencias se produce un cambio en el perfil de quienes donan sangre. En Chile, por ejemplo, durante las dos semanas siguientes al terremoto la razón hombre/mujer en los donantes se invirtió, con 61,1 por ciento de participación por parte de las mujeres, quienes en la semana previa al evento representaban a solo 37 por ciento.

In vitro antagonism of rabeprazole and metronidazole upon clinical isolates of Helicobacter pylori.

BACKGROUND: Rabeprazole inhibits Helicobacter pylori in vitro. This property could influence the antibacterial activity of metronidazole or amoxicillin. Our goal was to evaluate in vitro the effect of rabeprazole upon the antibacterial activity of metronidazole and amoxicillin. METHODS: The minimal inhibitory concentration (MIC) was determined by agar dilution upon 30 clinical isolates, and the antibacterial effect of the combined drugs was estimated by calculating the fractional inhibitory concentration index (FICI). RESULTS: Nine strains (30%) were resistant to metronidazole (MIC 8-256 mg/l) while only 1 strain was resistant to amoxicillin (MIC 1.0 mg/l). Rabeprazole also inhibited H. pylori (MIC 0.125-1.0 mg/l). The association of metronidazole and rabeprazole showed synergism in 30% of the strains (FICI < or =0.25), but also antagonism in 23.3% of the clinical isolates (FICI > or =4.0). Mostly, amoxicillin-rabeprazole showed an effect of synergism (53.3%). CONCLUSION: The results presented suggest the need to keep in mind that failure in eradication therapies based on metronidazole and rabeprazole could be due to an antagonism of the drugs.
