RESUMO

Adequate stem cell harvesting is required for autologous hematopoietic transplantation. In deficient mobilizer patients, the collection of stem cells can be challenging because of the impossibility of achieving satisfactory CD34 cell counts with GCSF + - chemotherapy. Plerixafor is a potent and expensive drug that promotes the release of stem cells from the medullary niche to the peripheral blood and allows satisfactory harvests. We performed a retrospective analysis of 370 patients with myeloma and lymphoma harvested at our institution. 99 % of patients achieved satisfactory apheresis using Plerixafor in 45 %. Satisfactory harvests were obtained in patients mobilized with GCSF or plerixafor. In patients who used plerixafor, it was necessary to perform fewer apheresis procedures (P = 0.05). In multivariate analysis, the only factor that predicted the need for plerixafor was the presence of less than 30,000 CD34 / ul on the day of apheresis (OR 0.3. p < 0.001). Since we adopted the plerixafor protocol guided by CD34 counts, the number of patients with harvest failure has decreased. In conclusion, the rational and standardized use of plerixafor favors satisfactory harvest in patients who require autologous transplantation in South-American patients.

RESUMO

Mosquito-borne diseases constitute a significant global impact on public and animal health. Climatic variables are recognized as major drivers in the mosquitoes' life history, principally rainfall and temperature, which directly influence mosquito abundance. Likewise, urbanization changes environmental conditions, and understanding how environmental variables and urbanization influence mosquito dynamics is crucial for the integrated management of mosquito-borne diseases, especially in the context of climate change. In this study, our aim was to observe the effect of temperature, rainfall, and the percentage of impervious surface on the abundance of mosquito species over a temporal scale of one complete year of fortnightly samplings, spanning from June 2021 to June 2022 in Yucatan, Mexico. We selected nine localities along an urbanization gradient (three natural, three rural, and three urban) from Mérida City to Reserva de la Biosfera Ría Celestún. Using BG-traps, mosquitoes were collected biweekly at each locality. Additionally, we estimated the percentage of impervious surface. Daily data of the maximum, mean and minimum temperatures, diurnal temperature range and rainfall were accumulated weekly. We calculated the accumulated quantities of temperatures and rainfall and lagged from one to four weeks before sampling for each locality. Generalized linear mixed models were then performed to study the influence of environmental variables and percentage of impervious surfaces on each of the 15 most abundant species. A total of 131,525 mosquitoes belonging to 11 genera and 49 species were sampled with BG-Sentinel traps baited with BG-lure and dry ice. The most frequently significative variable is the accumulated precipitation four weeks before the sampling. We observed a positive relationship between Cx. quinquefasciatus and Cx. thriambus with the diurnal temperature range. For Ae. aegypti, we observed a positive relationship with minimum temperature. Conversely, the percentage of impervious surface serves as a proxy of anthropogenic influence and helped us to distinguishing species exhibiting habitat preference for urban and rural environments, versus those preferring natural habitats. Our results characterize the species-specific effects of environmental variables (temperature, rainfall and impervious surface) on mosquito abundance.

RESUMO

Introduction: Given the ensuing increase in bone and periodontal diseases and defects, de novo bone repair and/or regeneration strategies are constantly undergoing-development alongside advances in orthopedic, oro-dental and cranio-maxillo-facial technologies and improvements in bio-/nano-materials. Indeed, there is a remarkably growing need for new oro-dental functional biomaterials that can help recreate soft and hard tissues and restore function and aesthetics of teeth/ dentition and surrounding tissues. In bone tissue engineering, HydroxyApatite minerals (HAp), the most stable CaP/Calcium Phosphate bioceramic and a widely-used material as a bone graft substitute, have been extensively studied for regenerative medicine and dentistry applications, including clinical use. Yet, limitations and challenges owing principally to its bio-mechanical strength, exist and therefore, research and innovation efforts continue to pursue enhancing its bio-effects, particularly at the nano-scale. Methods: Herein, we report on the physico-chemical properties of a novel nanoHydroxyApatite material obtained from the backbone of Salmon fish (patent-pending); an abundant and promising yet under-explored alternative HAp source. Briefly, our nanoS-HAp obtained via a modified and innovative alkaline hydrolysis-calcination process was characterized by X-ray diffraction, electron microscopy, spectroscopy, and a cell viability assay. Results and Discussion: When compared to control HAp (synthetic, human, bovine or porcine), our nanoS-HAp demonstrated attractive characteristics, a promising biomaterial candidate for use in bone tissue engineering, and beyond.

RESUMO

RESUMEN Dientamoeba fragilis es un protozoário que parasita el intestino grueso del hombre y animales domésticos. Hasta el momento, aún no son claros aspectos de su ciclo de vida, como el rango de hospedadores, reservorios, mecanismo de infección, entre otros. Se postula que el cerdo es un hospedador natural para este protozoario y que, debido a su cercanía con el humano, podría facilitar una transmisión zoonótica. En Colombia no existen a la fecha estudios sobre la presencia de D. fragilis en hospedadores animales, incluidos los cerdos, y los datos sobre la prevalencia de otros protozoarios intestinales en estos animales son escasos. El objetivo fue determinar la frecuencia de protozoarios intestinales, incluyendo D. fragilis, en cerdos de una granja tecnificada de una zona rural de Medellín (región Andina de Colombia). Se recolectaron muestras de materia fecal de 70 cerdos en etapa de preceba, que fueron evaluadas mediante examen directo, tinción tricrómica y Ziehl-Neelsen modificado. Se realizaron análisis univariados con medidas de frecuencia relativa y tendencia central y análisis bivariados para la exploración de factores de riesgo. Se detectó la presencia de D. fragilis en un 13% de las muestras y de otros parásitos como Entamoeba spp. (66%), Blastocystis spp. (64%), Balantioides coli (36%), Cryptosporidium spp. (36%), Iodamoeba butschlii (17%), coccidias (4%) y Giardia spp. (1,4%). En este primer reporte de D. fragilis en cerdos en Colombia se observó la alta prevalencia de otros protozoarios patógenos, lo que corrobora el papel de los cerdos como importantes reservorios de infecciones humanas. Estudios sobre la presencia de este protozoario tanto en cerdos como en el personal encargado de su manejo contribuirían al conocimiento sobre su dinámica de transmisión.

ABSTRACT Dientamoeba fragilis is a protozoan that parasitizes the large intestine of humans and domestic animals. To date, some aspects regarding D. fragilis life cycle, including hosts, reservoirs, infection mechanism, among others, are not yet clear. Swine are considered natural hosts for this protozoan, therefore their close contact with humans promotes its zoonotic transmission. In Colombia there are no studies on the presence of D. fragilis in animal hosts, including pigs, and data about other intestinal protozoa are scarce. The objective was to determine the prevalence of intestinal protozoan, including D. fragilis, in pigs raised in a farm from a rural area of Medellin (Andean region of Colombia). Fecal samples from 70 pigs in prefattening stage were collected. Direct fecal smear examination, trichrome and modified Ziehl-Neelsen stain were used in the study. Univariate analysis (frequency distribution and central tendency measures) and bivariate analysis were used to explore risk factors. Dientamoeba fragilis was found in 13% of the evaluated fecal samples. Other parasites detected included: Entamoeba spp. (66%), Blastocystis spp. (64%), Balantioides coli (36%), Cryptosporidium spp. (36%), Iodamoeba butschlii (17%), coccidias (4%), and Giardia spp. (1,4%). This is the first report of D. fragilis in swine in Colombia, and the high prevalence of other pathogen protozoa was also observed, which corroborates the role of pigs as important reservoirs for human infections. Studies focused on the evaluation of both swine and swine-exposed farm workers should be done in order to know the dynamics of transmission of this parasite.

RESUMO

SETTING: Over 150 potentially pathogenic non-tuberculous mycobacteria (NTM) species have been described, posing an onerous challenge for clinical laboratory diagnosis. OBJECTIVE: To evaluate different approaches for the identification of 40 clinically relevant NTM isolates whose species were not reliably identified using our routine diagnostic workflow comprising phenotypic tests and hsp65 polymerase chain reaction restriction analysis. DESIGN: We used 1) sequencing analysis of four conserved gene targets: 16S rRNA, rpoB, hsp65 and sodA; 2) two commercial reverse hybridisation assays; and 3) protein analysis using matrix-assisted laser desorption/ionisation time of flight mass spectrometry (MALDI-TOF MS). RESULTS: Combined, but not individual, sequence analysis allowed reliable species identification for 30/40 (75%) isolates, including species previously unknown to be circulating in Argentina. Commercial kits outperformed our routine identification in only 5/35 isolates, and misclassified many more. MALDI-TOF MS accurately identified species in 22/36 (61%) isolates and did not misidentify any. CONCLUSIONS: Commercial kits did not resolve the problem of species of NTM isolates that elude identification. Combined DNA sequence analysis was the approach of choice. MALDI-TOF MS shows promise as a powerful, rapid and accessible tool for the rapid identification of clinically relevant NTM in the diagnostic laboratory, and its accuracy can be maximised by building up a customised NTM spectrum database.

RESUMO

BACKGROUND: Colorectal cancer is one of the most frequent cancers in both sexes and the most frequent in the developed countries, if men and women are considered together as a group. It has an important associated morbidity and mortality in all countries and constitutes a public health problem with a high direct and indirect economic cost. The number of workdays lost due to temporary disability (TD) is one of the quantifiable references of these indirect costs. AIMS: To determine the indirect cost associated with TD due to colorectal cancer in Spain during the year 2011, a cost that aids in the prevention cost/benefit estimation. METHODS: The number of TD processes, the number of workdays lost due to TD, and the mean duration of those processes, based on the CIE 9-MC codes related to this pathology, as well as the calculated cost, using the Spanish minimum wage as a reference, during the period of January to December 2011, were all reviewed. RESULTS: Colorectal cancer in Spain during 2011 represented 1,046 TD processes, 202,784 workdays lost, and a mean process duration of 194 days/year. The resulting cost of the pathology due to TD was 4,335,521.92 euros. CONCLUSIONS: These results are beneficial for evaluating the usefulness of implementing public health support strategies for a greater reduction in colorectal cancer prevalence and mortality, and an improvement in quality of life of the affected individuals and their families, together with an economic savings resulting from a reduction in TD as a consequence of this disease.

RESUMO

To more accurately define the taxonomic relationships among species belonging to the genus Mycobacterium we have applied and compared three complete genome sequence comparison procedures to existing systems. These included a nucleotide sequence comparison including both coding and no-coding regions of the genome and two genomic-order comparisons using MAUVE and M-GCAT software to provide comparative gene synteny. These methods clearly differentiated a panel of genomes from reference mycobacterial species. Overall, the speciation of bacteria through determination of gene rearrangements were consistent with the gold standard method for species definition in bacteria, DNA-DNA hybridization however within the context of this system, individual components of the Mycobacterium tuberculosis complex (MTBC) did not show sufficient diversity to classify them as a separate species. The high number of gene rearrangements observed between the species tested suggests that gene reorganization of the genome represents an important contributor to speciation within the genus Mycobacterium and other related genera. The absence of rearrangements amongst MTBC supports their consideration as a single genospecies. Some gene rearrangements provided clear internal synteny between genomes of mycobacterial strains belonging to a same species and we suggest these could be used to classify subspecies.

RESUMO

The lining of the uterus and cervix might be injured by a variety of oxidation products of Cu in a Cu-IUD, including cuprous ions, dissolved and precipitated cupric ions, and reactive oxygen species such as superoxide radicals, hydrogen peroxide, and hydroxyl radicals. In this study, the human amnious WISH cell line was employed as a model of uterine cells in the presence of copper. The cell viability was decreased by elemental copper, which was alleviated up to 70% by the addition of catalase. The addition of copper oxychloride caused cell death in a dose-dependent manner. Hydroxyl radicals in the presence of copper were determined by the formation of malondialdehyde. Soluble cuprous chloride complexes are formed in the uterus by slowly entering oxygen. The complexes are partly oxidized to insoluble copper oxychloride. which damages the endometrium. Unoxidized cuprous ions migrate to the oxygen-rich cervix and are oxidized to copper oxychloride, causing cervix damage.

RESUMO

BACKGROUND: The aim of the present study was to analyze the epidemiological and clinical characteristics of poisoning by organophosphorus insecticides in the province of Almería. METHODS: One hundred eighty-seven patients diagnosed with organophosphorus insecticide poisoning were included from 1981-1986. In all the cases a previously established clinic and therapeutic protocol was applied. RESULTS: Eighty-six percent of the patients were males with a mean age of 31 years. The poisoning was accidental in 62% of the cases and attempted suicide in 38%. The via of absorption was cutaneous-respiratory in 57% and digestive in 43% of the patients. All the patients presented florid initial cholinergic symptomatology. The presence of bronchorrhea, tremor-fasciculations, respiratory depression and diminution in the level of conscience was associated with severe intoxication. The quantification of acetylcolinesterase was useful as a diagnostic parameter. Global mortality was 4%. Ten percent of the patients developed delayed signs of neurotoxicity. CONCLUSIONS: The high hospital demand for poisoning by organophosphorus insecticide is of note. Hospital mortality is low. The severity of intoxication is related with attempts of autolysis, digestive absorption, appearance of respiratory manifestations and of the central nervous system and the development of complications.
