Abstract

Objetivos: Identificar mediante el método de hibridización por colony blot las toxinas de Escherichia coli enterotoxigénica y relacionar los resultados con los serotipos encontrados. Materiales y métodos: se evaluaron todas las cepas de E. Coli recolectadas en el Hospital de Emergencias Pediátricas de Lima durante los meses de diciembre de 1998 - abril 1999. Se usaron dos sendas de ADN que identificaban el gen de la toxina termolábil (LT) y el de la toxina termoestable (ST) Para la detección de los serotipos se usaron 22 antisueros de diferentes categorías de E. coli. Resultados: se encontraron 233 cepas de E. coli, 27,9% de E. coli poseían el gen LT, 3,0% el gen ST y 1,3% tenían ambos. Conclusiones: los serotipos y la presencia de los genes LT y ST no necesariamente tienen relación, demostrándose que la identificación serológica es importante en el estudio epidemiológico de diarreas causadas por E. coli debiéndose confirmar la identificación de las categorías patogénicas mediante la detección de factores de virulencia.

Abstract

Este estudio de ribotipificación en 75 cepas de Vibrio cholerae O1 permitió identificar tres variantes ribotípicas, referidas como Per1, Per2 y Per3, aisladas durante el periodo 1991- 1999 en el Perú. La variante Per1 fue reportada tanto en la etapa epidémica y endémica del cólera, mientras que Per2 y Per3 se relacionaron sólo con la etapa endémica. Los resultados mostraron además una aparición constante y mayoritaria de la variante Per1, poniendo en evidencia la emergencia de un mismo grupo clonal en los brotes epidémicos del Perú. Las variantes ribotípicas encontradas fueron comparadas con los ribotipos de diferentes cepas referenciales de V. cholerae previamente caracterizadas. Se observó una identidad total del ribotipo Per1 con la variante ribotípica de aislamientos Asiáticos (Tailandia), encontrándose además altos índices de similitud entre los ribotipos Per1, Per2 y Per3, y evidenciándose una estrecha relación entre las cepas peruanas y los aislamientos asiáticos.

Abstract

La resistencia a los antimicrobianos es un problema de salud pública, en este caso se presentan los resultados de la resistencia antimicrobiana de Salmonella, Shigella y Vibrio cholerae entre los años 1997 y 2002 de las cepas confirmadas por el Instituto Nacional de Salud, procedentes de los laboratorios referenciales regionales de las diferentes direcciones de salud del Perú. La confirmación se realizó mediante bioquímica y serotipificación; para las pruebas de sensibilidad se utilizó el método de disco difusión. Se evaluaron un total de 542 cepas de Salmonella, 1034 de Shigella y 603 de Vibrio cholerae. La resistencia de Shigella frente a ampicilina muestra un promedio de 74,4% durante los 6 años; cloramfenicol con 65,9 %, cotrimoxazol con 72,2 %. En Salmonella se observa un promedio de 3,46 % para ampicilina; 2,83 % para cloranfenicol; en gentamicina 3,9 % y cotrimoxazol 1,1. V. Cholerae entre 1997 y 1999 mostraron promedios de resistencia de 19 % a cotrimoxazol, 12,1 % a tetraciclina y 10,2 % a ampicilina. A partir del año 2000, no se reportaron casos, por lo que se recibieron pocas cepas de esta especie. Se evidencia el problema de resistencia de Shigella frente a ampicilina, cloramfenicol y cotrimoxazol.

Abstract

Entre las Escherichia coli diarreogénicas la categoría E. coli enteroagregativa (ECEA) es una de las más importantes y frecuentemente asociada a diarreas infantiles. El presente estudio se realizó con la finalidad de detectar los factores de virulencia que caracterizan a esta categoría patogénica mediante hibridación por colony blot usando sondas de ADN específicas. Se evaluaron 233 cepas aisladas en el laboratorio del Hospital de Emergencias Pediátricas durante los meses de diciembre 1998 y abril de 1999. Del total de muestras analizadas, se encontró que 17,16% de las cepas poseen el factor de virulencia característico de esta categoría. Los resultados obtenidos demuestran que un importante número de aislamientos de niños con diarrea presentan E. coli enteroagregativa.

Abstract

Resumen Introducción: La temprana detección viral en infecciones respiratorias agudas (IRA) es esencial para establecer una terapia apropiada y prevenir el contagio intrahospitalario. Objetivo: Comparar la eficacia de la técnica de inmunofluorescencia indirecta (IFI) con la reacción de polimerasa en cadena (RPC) para identificar virus respiratorios en niños hospitalizados por IRA. Métodos: Se incluyeron 47 aspirados nasofaríngeos de niños ≤ 2 años con IRA. La IFI incluyó virus respiratorio sincicial (VRS), adenovirus, influenza A y B y parainfluenza. La RPC incluyó, además, la detección de metapneumovirus, enterovirus/rinovirus, bocavirus y coronavirus. Se estimó sensibilidad, especificidad, valor predictor positivo y negativo (VPP/VPN) y correlación kappa para VRS mediante IFI en comparación a la RPC. Resultados: La IFI detectó únicamente VRS (29; 61,7%). La RPC detectó diversos virus, entre ellos VRS en 26 casos (55,3%), seguido por bocavirus (29,8%), enterovirus/ rinovirus (21,3%), adenovirus (14,9%) y parainfluenza (4,3%) entre otros, con 35,5% de co-infección. La IFI presentó sensibilidad: 85,7%, especificidad: 73,6%, VPP: 82,7%, VPN: 77,7% y kappa: 0,5990 (IC 95%; 0,36360,8346) para VRS. Conclusión: La IFI presenta buena sensibilidad, pero moderada especificidad para VRS. Sin embargo, falla en la detección de otros virus respiratorios. La introducción de RPC permitiría mejorar el diagnóstico etiológico de las IRA de origen viral.

Abstract

The electrochemical regeneration of an activated carbon cloth exhausted with a common herbicide (bentazone) was investigated under different operating conditions. The reversibility of the desorption process was confirmed by monitoring the UV spectra of the solution while cathodic polarization is being applied. Neither nanotextural nor chemical changes are produced in the carbon cloth upon polarization in the absence of the adsorbate. Upon cathodic polarization of a carbon cloth working electrode preloaded with bentazone, negative charges appear on the surface. A partial bentazone desorption results from repulsive electrostatic interactions between the negative charges on the carbon cloth and bentazone. When the electrode potential is below the thermodynamic value for cathodic decomposition of water, hydroxyl ions are liberated. Such ions provoke local pH changes that are responsible of the dissociation of bentazone and carbon surface groups to their anionic form. As a consequence of the pH increase, an almost reversible desorption of bentazone is observed. The effects of several operating parameters on the regeneration efficiency were evaluated. Higher regeneration efficiencies were attained under potentiostatic as compared to galvanostatic conditions, as OH- production strongly depends on the applied potential.

Abstract

Los estudios de tomografía computada corresponden al 10% del total de los estudios radiológicos pero superan el 40% de la dosis de radiación colectiva al paciente. Ello ha generado una gran presión internacional por reducir las dosis en tomografía computada. Se revisaron los protocolos vigentes en estudio de cefalea, abdomen, disfunción patelo-femoral y sinusitis. Ellos conforman aproximadamente el 60 % de los estudios de tomografía computada en un centro hospitalario. Esta revisión, tanto bibliográfica como de series técnicas propias, permitieron reducir las dosis de radiación al paciente en un 30% a un 50% de sus valores originales. Ello sin disminuir su calidad diagnóstica y con obvio beneficio para el paciente Tomography studies are less than 10% of the total number of imaging studies but deliver more than 40% of the total collective dose to those patients. This situation has generated an increasing number of initiatives to reduce tomography doses. We analysed our routine CT protocols for headache, abdomen, patellofemoral dysfunction and sinusitis; they conform 60% of our total demand for CT examinations in a hospital setting. This revision enabled us to reduce the dose the patient in 30 to 50% of their original values. Diagnostic quality was maintained and the benefit to the patient is obvious

Abstract

© 2020, The Author(s), under exclusive licence to Springer Nature Limited.Lithium is a first-line medication for bipolar disorder (BD), but only one in three patients respond optimally to the drug. Since evidence shows a strong clinical and genetic overlap between depression and bipolar disorder, we investigated whether a polygenic susceptibility to major depression is associated with response to lithium treatment in patients with BD. Weighted polygenic scores (PGSs) were computed for major depression (MD) at different GWAS p value thresholds using genetic data obtained from 2586 bipolar patients who received lithium treatment and took part in the Consortium on Lithium Genetics (ConLi+Gen) study. Summary statistics from genome-wide association studies in MD (135,458 cases and 344,901 controls) from the Psychiatric Genomics Consortium (PGC) were used for PGS weighting. Response to lithium treatment was defined by continuous scores and categorical outcome (responders versus non-responders) using measurements on the Alda scale. Associations between PGSs of MD and lithium treatment response were assessed using a linear and binary logistic regression modeling for the continuous and categorical outcomes, respectively. The analysis was performed for the entire cohort, and for European and Asian sub-samples. The PGSs for MD were significantly associated with lithium treatment response in multi-ethnic, European or Asian populations, at various p value thresholds. Bipolar patients with a low polygenic load for MD were more likely to respond well to lithium, compared to those patients with high polygenic load [lowest vs highest PGS quartiles, multi-ethnic sample: OR = 1.54 (95% CI: 1.18–2.01) and European sample: OR = 1.75 (95% CI: 1.30–2.36)]. While our analysis in the Asian sample found equivalent effect size in the same direction: OR = 1.71 (95% CI: 0.61–4.90), this was not statistically significant. Using PGS decile comparison, we found a similar trend of association between a high genetic loading for MD and lower response to lithium. Our findings underscore the genetic contribution to lithium response in BD and support the emerging concept of a lithium-responsive biotype in BD.

Abstract

Lithium is the gold standard therapy for Bipolar Disorder (BD) but its effectiveness differs widely between individuals. The molecular mechanisms underlying treatment response heterogeneity are not well understood, and personalized treatment in BD remains elusive. Genetic analyses of the lithium treatment response phenotype may generate novel molecular insights into lithium’s therapeutic mechanisms and lead to testable hypotheses to improve BD management and outcomes. We used fixed effect meta-analysis techniques to develop meta-analytic polygenic risk scores (MET-PRS) from combinations of highly correlated psychiatric traits, namely schizophrenia (SCZ), major depression (MD) and bipolar disorder (BD). We compared the effects of cross-disorder MET-PRS and single genetic trait PRS on lithium response. For the PRS analyses, we included clinical data on lithium treatment response and genetic information for n = 2283 BD cases from the International Consortium on Lithium Genetics (ConLi+Gen; www.ConLiGen.org). Higher SCZ and MD PRSs were associated with poorer lithium treatment response whereas BD-PRS had no association with treatment outcome. The combined MET2-PRS comprising of SCZ and MD variants (MET2-PRS) and a model using SCZ and MD-PRS sequentially improved response prediction, compared to single-disorder PRS or to a combined score using all three traits (MET3-PRS). Patients in the highest decile for MET2-PRS loading had 2.5 times higher odds of being classified as poor responders than patients with the lowest decile MET2-PRS scores. An exploratory functional pathway analysis of top MET2-PRS variants was conducted. Findings may inform the development of future testing strategies for personalized lithium prescribing in BD.

Abstract

Background and Objectives: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and fine needle biopsy (FNB) are effective techniques that are widely used for tissue acquisition. However, it remains unclear how to obtain high-quality specimens. Therefore, we conducted a survey of EUS-FNA and FNB techniques to determine practice patterns worldwide and to develop strong recommendations based on the experience of experts in the field. Methods: This was a worldwide multi-institutional survey among members of the International Society of EUS Task Force (ISEUS-TF). The survey was administered by E-mail through the SurveyMonkey website. In some cases, percentage agreement with some statements was calculated; in others, the options with the greatest numbers of responses were summarized. Another questionnaire about the level of recommendation was designed to assess the respondents' answers. Results: ISEUS-TF members developed a questionnaire containing 17 questions that was sent to 53 experts. Thirty-five experts completed the survey within the specified period. Among them, 40% and 54.3% performed 50–200 and more than 200 EUS sampling procedures annually, respectively. Some practice patterns regarding FNA/FNB were recommended. Conclusion: This is the first worldwide survey of EUS-FNA and FNB practice patterns. The results showed wide variations in practice patterns. Randomized studies are urgently needed to establish the best approach for optimizing the FNA/FNB procedures.

Abstract

Background and Objectives: Currently, pancreatic cystic lesions (PCLs) are recognized with increasing frequency and have become a more common finding in clinical practice. EUS is challenging in the diagnosis of PCLs and evidence-based decisions are lacking in its application. This study aimed to develop strong recommendations for the use of EUS in the diagnosis of PCLs, based on the experience of experts in the field. Methods: A survey regarding the practice of EUS in the evaluation of PCLs was drafted by the committee member of the International Society of EUS Task Force (ISEUS-TF). It was disseminated to experts of EUS who were also members of the ISEUS-TF. In some cases, percentage agreement with some statements was calculated; in others, the options with the greatest numbers of responses were summarized. Results: Fifteen questions were extracted and disseminated among 60 experts for the survey. Fifty-three experts completed the survey within the specified time frame. The average volume of EUS cases at the experts' institutions is 988.5 cases per year. Conclusion: Despite the limitations of EUS alone in the morphologic diagnosis of PCLs, the results of the survey indicate that EUS-guided fine-needle aspiration is widely expected to become a more valuable method.

Abstract

Background: Serotonergic genes have been widely investigated regarding antidepressant response in major depressive disorder (MDD) but results are still not univocal. Methods: 159 MDD patients treated with citalopram were genotyped and evaluated by the 21-item Hamilton Depression Rating Scale at the beginning and every 4 weeks during the 12-week follow-up. Four serotonin-related genetic variants were tested for association with treatment outcome: tryptophane hydroxylase 1 (TPH1) rs1800532, monoamine oxidase A µVNTR, serotonin 2A receptor rs6311 and serotonin 2C receptor rs6318. The effect of these polymorphisms was tested both in the whole sample and in depressive subtypes with usually higher clinical severity: psychotic and melancholic MDD. Results: No effect on response, remission and symptom improvement was found for the four polymorphisms. However, rs1800532 was found to affect the outcome depending on the MDD subtype: the A allele predicted worse response both in MDD with psychotic (F(6, 378) = 2.90; p = 0.009) and melancholic (F(6, 381) = 2.86; p = 0.0097) features. Conclusions: The A allele at TPH1 rs1800532 may be associated with citalopram efficacy only in melancholic and psychotic MDD. These results suggest the usefulness of investigating the effect of genetic variants in conjunction with specific clinical features.

Abstract

RATIONALE: The endocannabinoid system has been implicated in the pathogenesis of major depression (MD) as well as in the mediation of antidepressant drug effects. OBJECTIVES: To analyze CNR1 gene variants in MD and clinical response to citalopram (selective serotonin re-uptake inhibitors [SSRI]). METHODS: The role of CNR1 gene (rs806368, rs1049353, rs806371, rs806377 and rs1535255) was investigated in 319 outpatients with MD and 150 healthy individuals. A subsample of 155 depressive patients were treated with citalopram and evaluated for response (fourth week) and remission (12th week) by the 21-item Hamilton Depression Rating Scale (HDRS). RESULTS: We observed a higher frequency of rs806371 G carriers in MD patients with both presence of melancholia (p = 0.018) and psychotic symptoms (p = 0.007) than in controls. Haplotype frequency distributions between MD sample and controls showed a significant difference for Block 1 (rs806368-rs1049353-rs806371) (p = 0.008). This haplotype finding was consistent when we compared controls with MD subsample stratified by melancholia (p = 0.0009) and psychotic symptoms (p = 0.014). The TT homozygous of the rs806368 and rs806371 presented more risk of no Remission than the C carriers (p = 0.008 and 0.012, respectively). Haplotype frequency distributions according to Remission status showed a significant difference for Block 1 (p = 0.032). Also, we observed significant effect of time-sex-genotype interaction for the rs806368, showing that the C carrier men presented a better response to antidepressant treatment throughout the follow-up than TT homozygous men and women group (p = 0.026). CONCLUSIONS: These results suggest an effect of CNR1 gene in the etiology of MD and clinical response to citalopram.

Abstract

BACKGROUND: Dysbindin gene (dystrobrevin-binding-protein 1, DTNBP1) variants have been associated with several psychiatric conditions including mood disorders and antidepressant efficacy. We investigated dysbindin gene (DTNBP1) variants in major depression and clinical response to selective serotonin reuptake inhibitors. METHODS: In this study we investigated the role of DTNBP1 gene (rs3213207, rs2005976, rs760761 and rs2619522) in 313 major depressive outpatients and 149 healthy individuals. One hundred and forty-seven depressive patients were treated with citalopram and evaluated for response (4th week) and remission (12th week) by the 1-item Hamilton Depression Rating Scale. Single nucleotide polymorphisms (SNPs) were assayed by using Applied Biosystems TaqMan technology. RESULTS: Genotype and haplotype frequencies for four SNPs within DTNBP1 gene did not significantly differ between patients and controls. Allele distribution of SNP rs760761, however, showed a trend of difference between responders and nonresponders (4th week). Haplotype analyses produced a significant association with response to treatment at week 4. No differences were found in remission (12th week). DISCUSSION: DTNBP seems to have an effect on short-term clinical response to citalopram. New studies focused on other genes involved in glutamatergic neurotransmission and related proteins could help to elucidate the complex mechanism of clinical response to antidepressants.
