RESUMO

PURPOSE: The present study aimed to identify, through a critical review of the literature, the success factors associated with the splinting of fixed prostheses on adjacent implants of the posterior sectors in partially edentulous patients compared with those not splinted. STUDY SELECTION: A MEDLINE strategy was implemented based on a research question to systematically search and extract information from databases (PubMed and Scopus) using MeSH terms/keywords identified for each domain. Systematic reviews, clinical and in vitro studies were selected and classified according to eligibility criteria based on the research question and level of evidence using the PRISMA flowchart. RESULTS: A total of 32 studies were selected for data extraction and analysis according to study design (three systematic reviews, 14 clinical studies, and 15 in vitro studies). Overall, the studies found no significant difference in the association between the survival rate and prosthesis type. In clinical studies, there have been no differences in marginal bone loss between splinted and non-splinted prostheses, and the influence of peri-implant status and restorative materials has been poorly evaluated. The distribution of stress and loads determined in the in vitro studies showed results that could favor splinted prostheses; however, are generally associated with implant design. CONCLUSIONS: The need for splinted or non-splinted adjacent implant-supported prostheses remains controversial. The reviewed evidence indicates that factors such as implant size and its relationship with coronal height could be important in decision-making.

RESUMO

Kosakonia cowanii strain Ch1 was isolated from Mexican chili powder, and the genome was sequenced. The genome was 4,765,544 bp in length, with an average G + C content of 56.22%, and a plasmid (pCh1) of 128,063 bp with an average G + C content of 52.50%. A phylogenetic analysis revealed a close relation with pathogenic strains; nevertheless, some virulence-related genes were absent, and this genetic characteristic may explain the fact that K. cowanii Ch1 behaved as a non-pathogenic strain when infection assays were performed on the leaves and fruits of Capsicum annuum L. Surprisingly, we observed that this bacterial strain had the ability to spread throughout serrano pepper seeds. Furthermore, K. cowanii Ch1 was evaluated for the production of volatile organic compounds (VOCs) against fungal pathogens, and the results showed that Alternaria alternata and Sclerotium rolfsii were inhibited in a radial mycelial growth assay by a mean rate of 70% and 64%, while Fusarium oxysporum was inhibited by only approximately 10%. Based on the headspace solid-phase microextraction combined with the gas chromatography mass spectrometry (HS-SPME-GC-MS), 67 potential VOCs were identified during the fermentation of K. cowanii Ch1 in TSA medium. From these VOCs, nine main compounds were identified based on relative peak area: dodecanoic acid; 3-hydroxy ethanol; 1-butanol-3-methyl; acetaldehyde; butanoic acid, butyl ester; cyclodecane; 2-butanone, 3-hydroxy; disulfide, dimethyl and pyrazine-2,5-dimethyl. Our findings show the potential of K. cowanii Ch1 for the biocontrol of fungal pathogens through VOCs production and reveal additional abilities and metabolic features as beneficial bacterial specie.

RESUMO

The potential presence of spore-forming bacteria related to the Bacillus cereus group in Mexican chili powder elaborated from Capsicum annuum L. is of commercial and clinical interest, because chili powder is an essential spice in the Mexican diet and in diets around the globe. To facilitate detection and isolation of members of this group of spore-forming bacteria from Mexican chili powder samples, we identified colonies that grew on agar medium selective for Bacillus cereus sensu lato, supplemented with polymyxin B (10 µg/mL) and ampicillin (10 to 100 µg/mL). The presumptive B. cereus (s.l.) isolates were tested using a tRNACys-PCR-based approach and the results identified species related phylogenetically to B. cereus, B. thuringiensis, and B. toyonensis. Their toxigenic potential was assessed by serological tests to detect enterotoxins (Nhe and Hbl) and by PCR targeting the hemolysin BL (hbl) component C (hblC) and non-hemolytic enterotoxin component A (nheA). The antibiotic profiles of the isolates showed a high resistance to ß-lactams (100% of the isolates), trimethoprim-sulfamethoxazole (100%), tetracycline (90%), erythromycin (77%), clindamycin (74%), and chloramphenicol (42%). Our results indicate the presence of B. cereus s.l. with toxigenic characteristics in Mexican chili powder. Because of the potential for these organisms to cause disease through their production of various toxins, and resistance to antibiotics, we recommend that a microbiological risk assessment must be considered in the Mexican regulatory requirements.

RESUMO

Resumen OBJETIVO: Estimar la prevalencia de depresión posparto y los factores asociados en usuarias del Hospital General Progreso, Acapulco, Guerrero, México. MATERIALES Y MÉTODOS: Estudio prospectivo, observacional y transversal de serie de casos. El instrumento para medir la depresión fue un cuestionario que incluyó la Escala de Depresión Posnatal de Edimburgo (EPDS por sus siglas en inglés). Además, a las pacientes se les preguntaron sus datos sociodemográficos, antecedentes de control prenatal, historial obstétrico, atención del parto y otros datos relacionados con su pareja. Mediante análisis bivariado y multivariado se estimaron los factores asociados con la depresión posparto. RESULTADOS: Se analizaron 485 pacientes con media de edad de 24.6 años y límites de 14 y 43 años. La prevalencia de depresión posparto fue de 16%. En el modelo final del análisis multivariado los factores asociados con la depresión posparto fueron: complicaciones en el parto (IC95%:1.61-6.54), antecedente de alcoholismo antes del embarazo (IC95%:1.17- 3.30) y recibir apoyo emocional del esposo durante el embarazo (IC95%: 0.17-0.68). CONCLUSIONES: El antecedente de consumo de bebidas alcohólicas, previo al embarazo, y tener alguna complicación del parto, fueron indicios de posible aparición de depresión posparto. Quienes la padecieron tuvieron la referencia temprana a los servicios de Psicología. La pareja debe estar informada que su apoyo emocional ayuda a reducir el riesgo de depresión posparto en la paciente.

Abstract OBJECTIVE: To estimate the prevalence of postpartum depression and associated factors in users of the Hospital General Progreso, Acapulco, Guerrero, Mexico. MATERIALS AND METHODS: Prospective, observational, cross-sectional case series study. The instrument to measure depression was a questionnaire that included the Edinburgh Postnatal Depression Scale (EPDS). In addition, patients were asked about their sociodemographic data, prenatal control history, obstetric history, delivery care and other data related to their partner. Factors associated with postpartum depression were estimated by bivariate and multivariate analyses. RESULTS: We analyzed 485 patients with a mean age of 24.6 years and cut-offs of 14 and 43 years. The prevalence of postpartum depression was 16%. In the final multivariate analysis model, the factors associated with postpartum depression were: delivery complications (CI95%:1.61-6.54), history of alcoholism before pregnancy (CI95%:1.17- 3.30) and receiving emotional support from husband during pregnancy (CI95%: 0.17-0.68). CONCLUSIONS: A history of alcoholic beverage consumption prior to pregnancy and having some complication of childbirth were indicative of possible occurrence of postpartum depression. Those who suffered from it had early referral to psychology services. The couple should be informed that their emotional support helps to reduce the risk of postpartum depression in the patient.

RESUMO

La hidatidosis es una enfermedad causada por el estado larval del platelminto Echinococcus, cuya especie más prevalente es Echinococcus granulosus. Se trata de un cuadro endémico en Eurasia, África, Australia y Sudamérica. En Chile, tiene una incidencia notificada de 2,1 casos por 100.000 habitantes y, pese a estar asociada a las zonas ganaderas del sur del país, se detecta en todo el territorio debido al desplazamiento de la población y a su largo período de incubación. Se caracteriza por la presencia de un quiste habitualmente en el hígado (75%) o los pulmones (15%). La afectación de otros sitios es menos frecuente y el compromiso óseo es raro, no supera el 1-2,5%, ya sea en el tejido trabecular o el canal medular. El tratamiento, en general, es médico-quirúrgico con resultados clínicos dispares debido a la alta tasa de recurrencias y las secuelas. La experiencia en el manejo de pacientes con hidatidosis intrarraquídea es limitada a causa de su baja frecuencia. Por este motivo, quisimos reportar dos casos atendidos en nuestro centro y analizar su manejo. Nivel de Evidencia: IV

Hydatidosis is a disease caused by the larval stage of Echinococcus, the most prevalent species being Echinococcus granulosus. Hydatidosis is endemic to Eurasia, Africa, Australia and South America. In Chile, it has a reported incidence of 2.1 cases per 100,000 inhabitants and, although it is associated with the livestock areas of southern Chile, there have been reports throughout the territory due to the displacement of the population and its long incubation period. It is characterized by the presence of a cyst usually at the hepatic (75%) or pulmonary (15%) level. The involvement of other regions is less common and bone involvement is a rarity that does not exceed a 1-2.5% prevalence, either in the trabecular tissue or spinal canal. A combined medical and surgical approach is the most common treatment which involves disparate clinical outcomes due to the high rate of recurrences and sequelae. Experience in the management of patients with intraspinal hydatidosis is limited because of their low frequency. Therefore, we wanted to report 2 cases treated in our center and to analyze the progress in its management. Level of Evidence: IV

RESUMO

OBJECTIVES: To characterize the paleodiet of individuals from Formative Period (1500 B.C.-A.D. 400) Atacama Desert sites of Ancachi and Quillagua as a means of understanding the dietary and cultural impacts of regional systems of exchange. MATERIALS AND METHODS: Thirty-one bone samples recovered from the cemetery of Ancachi (02QU175) and in/around the nearby town of Quillagua were the subject of carbon and nitrogen stable isotope analysis of bone collagen and hydroxyapatite and multisource mixture modeling (FRUITS, food reconstruction using isotopic transferred signals) of paleodiet. These individuals were compared with nearly 200 other Formative Period individuals from throughout the region to identify differences in dietary behaviors. RESULTS: 80.6% (25/31) of the samples yielded sufficient well-preserved collagen and were included in the multisource mixture model. The FRUITS model, which compared individuals with a robust database of available foods from the region, identified a wide diversity of diets in the Ancachi/Quillagua area (including both coastal and interior individuals), and, most notably, thirteen individuals who consumed an average of 11.2 ± 1.9% terrestrial animals, 19.8 ± 1.9% legumes, and 22.5 ± 3.1% marine fauna, a balanced pattern of protein consumption distinct from both the coastal and inland individuals in our larger regional sample. CONCLUSIONS: The combination of stable isotope analysis and multisource mixture modeling permitted the characterization of dietary behavior of 25 individuals from nodal sites in the Atacama Desert, thus enhancing our understanding of the economic and social relationships that bound together Formative Period sites, populations, and individuals in this hyperarid region.

RESUMO

Sedentary overweight or obese adult (age<60 years) women, allocated in type 2 diabetes mellitus (T2DM, n=13), dyslipidemia alone (DYS, n=12), dyslipidemia associated with hyperglycaemia (DYSHG, N=12), or healthy control (CON, n=10) groups, had their lipid, glucose, blood pressure, endurance performance, and anthropometry variables assessed before and after 16 weeks of a thrice-weekly high-intensity interval training (HIIT) program. Triglycerides reduced significantly (P<0.05) in all groups, and high-density lipoprotein increased (P<0.01) in T2DM, DYS and DYSHG; however, low-density lipoprotein reduced (P<0.05) only in DYSHG, and total cholesterol reduced (P<0.01) only in DYS and DYSHG. Fasting glucose reduced (P<0.05) significantly in T2DM, DYS and DYSHG, but with higher decreases in T2DM and DYSHG. Blood pressure, endurance performance and body composition improved (P<0.05) in all groups. The HIIT program was effective for restoring lipid profile of DYS and DYSHG, and fasting glucose of DYSHG to levels similar to those of CON, with a weekly time commitment 25% to 56% lower than the minimum recommended in current exercise guidelines. These findings suggest that HIIT may be a time-efficient intervention for counteracting dyslipidemia.

RESUMO

The aim of this article is to present a new face recognition system based on the fusion of visible and thermal features obtained from the most current local matching descriptors by maximizing face recognition rates through the use of genetic algorithms. The article considers a comparison of the performance of the proposed fusion methodology against five current face recognition methods and classic fusion techniques used commonly in the literature. These were selected by considering their performance in face recognition. The five local matching methods and the proposed fusion methodology are evaluated using the standard visible/thermal database, the Equinox database, along with a new database, the PUCV-VTF, designed for visible-thermal studies in face recognition and described for the first time in this work. The latter is created considering visible and thermal image sensors with different real-world conditions, such as variations in illumination, facial expression, pose, occlusion, etc. The main conclusions of this article are that two variants of the proposed fusion methodology surpass current face recognition methods and the classic fusion techniques reported in the literature, attaining recognition rates of over 97% and 99% for the Equinox and PUCV-VTF databases, respectively. The fusion methodology is very robust to illumination and expression changes, as it combines thermal and visible information efficiently by using genetic algorithms, thus allowing it to choose optimal face areas where one spectrum is more representative than the other.

RESUMO

The concept of network incorporates important advantages into the study of migrations. In the Ecuadorean case, it has been widely documented the way in which the migratory networks simulate and give shape to the migratory flow to Spain; how they manage to absorb the impact of the first phase of insertion and the way in which they keep channels of communication with the home society. As the migration projects extend, the debate about the immigrants incorporation into the host society becomes a priority. We are able to then observe the emergency of discourses which assign a generic potential to the networks created by the migrants in the host society in terms of social capital for the integration. Nevertheless, the case represented by the Ecuadoran resident women in the city of Seville forces us to question seriously that concepts like social capital or empowerment should be used to describe the effects of the social networks in the integration of the immigrants(AU)
