RESUMO
INTRODUCTION: Risk factors for developing pancreatitis due to thiopurines in patients with inflammatory bowel disease (IBD) are not clearly identified. Our aim was to evaluate the predictive pharmacogenetic risk of pancreatitis in IBD patients treated with thiopurines. METHODS: We conducted an observational pharmacogenetic study of acute pancreatitis events in a cohort study of IBD patients treated with thiopurines from the prospectively maintained ENEIDA registry biobank of GETECCU. Samples were obtained and the CASR, CEL, CFTR, CDLN2, CTRC, SPINK1, CPA1, and PRSS1 genes, selected based on their known association with pancreatitis, were fully sequenced. RESULTS: Ninety-five cases and 105 controls were enrolled; a total of 57% were women. Median age at pancreatitis diagnosis was 39 years. We identified 81 benign variants (50 in cases and 67 in controls) and a total of 35 distinct rare pathogenic and unknown significance variants (10 in CEL, 21 in CFTR, 1 in CDLN2, and 3 in CPA1). None of the cases or controls carried pancreatitis-predisposing variants within the CASR, CPA1, PRSS1, and SPINK1 genes, nor a pathogenic CFTR mutation. Four different variants of unknown significance were detected in the CDLN and CPA1 genes; one of them was in the CDLN gene in a single patient with pancreatitis and 3 in the CPA1 gene in 5 controls. After the analysis of the variants detected, no significant differences were observed between cases and controls. CONCLUSION: In patients with IBD, genes known to cause pancreatitis seem not to be involved in thiopurine-related pancreatitis onset.

This open-label, two-part, phase Ib drug-drug interaction study investigated whether the pharmacokinetic (PK) and safety profiles of lurbinectedin (LRB), a marine-derived drug, are affected by co-administration of itraconazole (ITZ), a strong CYP3A4 inhibitor, in adult patients with advanced solid tumors. In Part A, three patients were sequentially assigned to Sequence 1 (LRB 0.8 mg/m2, 1-h intravenous [IV] + ITZ 200 mg/day oral in Cycle 1 [C1] and LRB alone 3.2 mg/m2, 1 h, IV in Cycle 2 [C2]). In Part B, 11 patients were randomized (1:1) to receive either Sequence 1 (LRB at 0.9 mg/m2 + ITZ in C1 and LRB alone in C2) or Sequence 2 (LRB alone in C1 and LRB + ITZ in C2). Eleven patients were evaluable for PK analysis: three in Part A and eight in Part B (four per sequence). The systemic total exposure of LRB increased with ITZ co-administration: 15% for Cmax, area under the curve (AUC) 2.4-fold for AUC0-t and 2.7-fold for AUC0-∞. Co-administration with ITZ produced statistically significant modifications in the unbound plasma LRB PK parameters. The LRB safety profile was consistent with the toxicities described in previous studies. Co-administration with multiple doses of ITZ significantly altered LRB systemic exposure. Hence, to avoid LRB overexposure when co-administered with strong CYP3A4 inhibitors, an LRB dose reduction proportional to CL reduction should be applied.

PURPOSE: To describe a novel technique of nasolacrimal foreign body extraction in dogs by using a 20G vitreoretinal forceps introduced through the superior lacrimal punctum. METHODS: A retrospective review of the medical records of dogs with dacryocystitis due to nasolacrimal foreign bodies between the years 2001 and 2022 was performed. We recorded the breed, age, affected eye, type and number of foreign bodies, concomitant diseases, and the use of imaging techniques. All animals underwent the same procedure of a 20G vitreoretinal forceps insertion through the upper canaliculus reaching the lacrimal sac and retrograde extraction of the foreign bodies. RESULTS: A total of 28 dogs were included, 16 males and 12 females, with a mean (±SD) age of 4.7 (±3.2) years. The most common breeds were Wire-Haired Dachshund (4/28; 14.29%) and Labrador Retriever (3/28; 10.71%). Additional imaging techniques were used, such as orbital ultrasound in 13 cases (13/28; 46.43%) and computed tomography in one case (1/28; 3.57%). The most common type of foreign body retrieved was grass awns, although seeds and plant debris were also found. Dacryocystitis resolved after removal of the foreign body and appropriate medical therapy was ensured in all cases in the 1-month postprocedure follow-up. CONCLUSION: Extraction of nasolacrimal foreign bodies with vitreoretinal forceps is a novel, noninvasive, and easily applicable technique that, although not successful in all cases, can be attempted before performing more aggressive surgery.
RESUMO
INTRODUCTION: Psilocybin, a naturally occurring serotonergic agonist in some mushroom species, has shown promise as a novel, fast-acting pharmacotherapy seeking to overcome the limitations of conventional first-line antidepressants. Studying psilocybin effects on cognition and emotional processing may help to clarify the mechanisms underlying the therapeutic potential of psilocybin and may also support studies with people suffering from depression. Thus, this review aims to provide a comprehensive overview of the current literature regarding the effects of psilocybin on these two key areas in both healthy and depressed populations. METHOD: A systematic search was performed on 29 January 2024, in the PubMed, EBSCOhost, Web of Science and SCOPUS databases. After duplicates removal, study selection was conducted considering pre-specified criteria. Data extraction was then performed. The quality assessment of the studies was carried out using the Cochrane Collaboration tools for randomized (RoB 2.0) and non-randomized (ROBINS-I) controlled trials. RESULTS: Twenty articles were included, with 18 targeting healthy adults and two adults with depression. Results point to impairments within attentional and inhibitory processes, and improvements in the domains of creativity and social cognition in healthy individuals. In the population with depression, only cognitive flexibility and emotional recognition were affected, both being enhanced. The comparison of outcomes from both populations proved limited. CONCLUSIONS: Psilocybin acutely alters several cognitive domains, with a localized rather than global focus, in a dose- and time-dependent manner. However, the significant methodological constraints call for further research, in the context of depression and with standardized protocols, with longitudinal studies also imperative.
RESUMO
Early-life stress and subsequent high-calorie diets during adolescence are known to be risk factors for developing metabolic and psychological disorders. Although non-nutritive sweeteners such as stevia and sucralose have been a useful alternative to reduce sugar consumption, the effects of prolonged consumption of these sweeteners on metabolism and behavior in adolescents remain unclear. Here, we evaluated the effects of early-stress followed by access to stevia or sucralose during adolescence on weight gain, glycemia, and anxiety-related behaviors in male and female rats. During postnatal days (PNDs) 1-21, pups were separated twice a day, for 180 min each time, from their dam nest while non-separated pups served as controls. The pups were weaned, separated by sex and randomly distributed into the stevia, sucralose and water conditions. During PNDs 26-50, two bottles containing water and stevia or sucralose were placed in the animal home-cages, and body weight and blood glucose measures were scored. On PNDs 50 and 51, behavioral measures were obtained in the open-field test. Results showed that male rats consuming stevia reduced body weight gain, blood glucose and increased locomotion. Early-stress led to low blood glucose and alterations in anxiety and locomotion-related behaviors in a sex-dependent manner. Moreover, sucralose access during adolescence reversed the effects of early-stress on anxiety-related behaviors in female rats. The results suggest that the consumption of stevia and sucralose could be an alternative for the replacement of sugar-sweetened beverages, especially in adolescents who have had adverse early-life experiences.

Introduction: Perception and relief of pain exhibit variability among individuals. Age, gender, ethnicity, educational level, actual stress level, mood, or medical conditions can modify the personal interpretation of pain and responses to pharmacological treatment. These differences may play a significant role in the effects, sometimes unwanted, of analgesic treatment. Objectives: Define patient typologies with Failed Back Syndrome regarding attitudes toward the disease, treatment, healthcare, and the follow-up they receive from their healthcare professionals. Create a tool for patient profile identification. Materials and Methods: A clinical case series study, observational, descriptive, and cross-sectional. Study population: patients from the Pain Unit of Nuestra Señora de La Candelaria University Hospital (HUNSC) in Tenerife, conducted in three phases: collection of medical history data (F0), initial visit (F1), and personal interview (F2). Results: Five patient typologies are obtained based on responses to 17 items. Regression equations are calculated from these responses to predict the patient type. They are grouped into "Classics," "Dependents," "Critics," "Unconscious," and "Responsible." Additionally, two tools with 17 items and another with 7 optimized items are developed to simplify the process. Conclusions: These tools enable Community Pharmacy (CP) to identify patients based on their characteristics to direct personalized strategies for each of them.
RESUMO
There is an increase in the worldwide prevalence of congenital abdominal wall defects (CAWD), with gastroschisis (GS) and omphalocele (OC) being the most common. It is widely accepted that folic acid supplementation (FAS) in the maternal diet decreases the incidence of anomalies such as neural tube defects, but there is controversy regarding the possible beneficial role for other congenital malformations. Several epidemiological studies raise controversy regarding a possible relationship between vitamin supplementation with the occurrence of abdominal wall malformations. The aim of the present study is to obtain an updated review of the global frequency of CAWD in neonates and the relationship with FAS in the mothers. For this we have carried out a systematic search of epidemiological studies in different article databases between 2011 and 2022. The analysis of 25 studies conducted in different countries where cases of OC and/or GS are registered directly or together with other congenital defects shows that 60% inquire into the relationship of FAS with the incidence of CAWD. Half of them proposes a beneficial effect of FAS and the other half find no association, concluding that there is no unanimous evidence that FAS in the maternal diet decreases the incidence of CAWD. However, it seems that an influential factor to take into account is the nutritional habits of the mothers.
RESUMO
Eigenmannia is a highly diverse genus within the Sternopygidae family, comprising 30 species. Due to its complex taxonomy, molecular analyses have been crucial for species delimitation within this group. Therefore, the present study presents a genetic analysis using sequences of the mitochondrial gene cytochrome c oxidase subunit 1 (COI) in specimens previously identified through alpha taxonomy as E. correntes (with unpublished data), E. virescens, and E. trilineata, originating from various locations within the Upper Paraná and Paraguay River basins in Brazil. The molecular data confirm the taxonomic complexity of the genus, as individuals morphologically identified as E. virescens and E. trilineata shared the same haplotype (H52). Furthermore, the results of the species delimitation tests suggest that specimens morphologically identified as E. virescens belong to the species E. trilineata. In addition, samples morphologically identified as E. correntes may correspond to more than one Operational Taxonomic Units (OTUs). Furthermore, the intraspecific Kimura-2-parameter (K2P) distances within the different studied populations are significant. This study has contributed valuable information about genetic diversity in Eigenmannia, emphasizing the importance of using integrative analyses to resolve taxonomic conflicts within the group. It also supports biogeographical studies and assists in biodiversity conservation efforts.

This open-label, two-way, crossover, phase Ib drug-drug interaction study investigated whether the pharmacokinetics (PKs) and safety profile of lurbinectedin (LRB) are affected by co-administration of a moderate CYP3A4 inducer (bosentan, BOS) in adult patients with advanced solid tumors. Eleven patients were randomly assigned to Sequence 1 (LRB + BOS in Cycle 1 [C1] and LRB alone in Cycle 2 [C2]) or Sequence 2 (LRB alone in C1 and LRB + BOS in C2), and finally, eight patients (four per sequence) were considered evaluable for PK assessment. LRB (3.2 mg/m2, 1 h [h], intravenous) was administered alone or combined with multiple BOS administration (125 mg/12 h oral; 5.5 days). Co-administration with BOS decreased the systemic total exposure (area under the curve, AUC) of LRB by 21% for AUC0-t and 20% for AUC0-∞ and increased clearance by 25%. Co-administration with BOS did not significantly modify the unbound plasma LRB PK parameters. BOS increased the conversion of LRB to its metabolite M1, with no changes on its metabolite M4. The LRB safety profile was consistent with the toxicities previously described for this drug. No differences in terms of toxicity were found between LRB with and without BOS. In summary, the magnitude of the observed changes precludes a clinically relevant effect of BOS co-administration on LRB exposure and its safety profile.
RESUMO
Monocyte distribution width (MDW) has been associated with inflammation and poor prognosis in various acute diseases. Chronic obstructive pulmonary disease (COPD) exacerbations (ECOPD) are associated with mortality. The objective of this study was to evaluate the utility of the MDW as a predictor of ECOPD prognosis. This retrospective study included patient admissions for ECOPD. Demographic, clinical and biochemical information; intensive care unit (ICU) admissions; and mortality during admission were recorded. A total of 474 admissions were included. MDW was positively correlated with the DECAF score (r = 0.184, p < 0.001) and C-reactive protein (mg/dL) (r = 0.571, p < 0.001), and positively associated with C-RP (OR 1.115 95% CI 1.076-1.155, p < 0.001), death (OR 9.831 95% CI 2.981- 32.417, p < 0.001) and ICU admission (OR 11.204 95% CI 3.173-39.562, p < 0.001). High MDW values were independent risk factors for mortality (HR 3.647, CI 95% 1.313-10.136, p = 0.013), ICU admission (HR 2.550, CI 95% 1.131-5.753, p = 0.024), or either mortality or ICU admission (HR 3.084, CI 95% 1.624-5.858, p = 0.001). In ROC analysis, a combined MDW-DECAF score had better diagnostic power (AUC 0.777 95% IC 0.708-0.845, p < 0.001) than DECAF (p = 0.023), MDW (p = 0.026) or C-RP (p = 0.002) alone. MDW is associated with ECOPD severity and predicts mortality and ICU admission with a diagnostic accuracy similar to that of DECAF and C-RP. The MDW- DECAF score has better diagnostic accuracy than MDW or DECAF alone in identifying mortality or ICU admission.
RESUMO
Background: The usefulness of thiopurines has been poorly explored in pouchitis and other pouch disorders. Objective: To evaluate the effectiveness and safety of azathioprine as maintenance therapy in inflammatory pouch disorders. Design: This was a retrospective and multicentre study. Methods: We included patients diagnosed with inflammatory pouch disorders treated with azathioprine in monotherapy. Effectiveness was evaluated at 1 year and in the long term based on normalization of stool frequency, absence of pain, faecal urgency or fistula discharge (clinical remission), or any improvement in these symptoms (clinical response). Endoscopic response was evaluated using the Pouchitis Disease Activity Index (PDAI). Results: In all, 63 patients were included [54% males; median age, 49 (28-77) years]. The therapy was used to treat pouchitis (n = 37) or Crohn's disease of the pouch (n = 26). The rate of clinical response, remission and non-response at 12 months were 52%, 30% and 18%, respectively. After a median follow-up of 23 months (interquartile range 11-55), 19 patients (30%) were in clinical remission, and 45 (66%) stopped therapy. Endoscopic changes were evaluated in 19 cases. PDAI score decreased from 3 (range 2-4) to 1 (range 0-3). In all, 21 patients (33%) presented adverse events and 16 (25%) needed to stop therapy. Conclusion: Azathioprine may be effective in the long term for the treatment of inflammatory pouch disorders and could be included as a therapeutic option.
RESUMO
Early breast cancer patients often experience relapse due to residual disease after treatment. Liquid biopsy is a methodology capable of detecting tumor components in blood, but low concentrations at early stages pose challenges. To detect them, next-generation sequencing has promise but entails complex processes. Exploring larger blood volumes could overcome detection limitations. Herein, a total of 282 high-volume plasma and blood-cell samples were collected for dual ctDNA/CTCs detection using a single droplet-digital PCR assay per patient. ctDNA and/or CTCs were detected in 100% of pre-treatment samples. On the other hand, post-treatment positive samples exhibited a minimum variant allele frequency of 0.003% for ctDNA and minimum cell number of 0.069 CTCs/mL of blood, surpassing previous investigations. Accurate prediction of residual disease before surgery was achieved in patients without a complete pathological response. A model utilizing ctDNA dynamics achieved an area under the ROC curve of 0.92 for predicting response. We detected disease recurrence in blood in the three patients who experienced a relapse, anticipating clinical relapse by 34.61, 9.10, and 7.59 months. This methodology provides an easily implemented alternative for ultrasensitive residual disease detection in early breast cancer patients.
RESUMO
Resumen Se presentan resultados de una investigación empírica sobre problemas comportamentales en niños y niñas escolarizados entre 6 y 11 años. El objetivo principal es describir, desde la perspectiva epidemiológica, los problemas comportamentales de una muestra clínica (N = 395; edad: . = 7.92 y DE = 1.75) y de una muestra no clínica (N = 363; edad: . = 8.78 años y DE = 1.73). Son objetivos específicos el analizar las diferencias por sexo y variables sociodemográficas en ambos contextos: clínico y no clínico. No se efectuó un estudio comparativo entre ambas muestras. Se administró el formulario Child Behaviour Checklist (CBCL) y una encuesta sociodemográfica a los adultos responsables. El análisis cuantitativo se efectuó mediante estudios de frecuencia, distribución y asociaciones entre variables con el objetivo de describir a ambas muestras desde el punto de vista de los resultados del CBCL y de las variables sociodemográficas. Se estudiaron asociaciones entre los valores de las escalas de síndromes del CBCL y las variables sociodemográficas mediante el análisis de la varianza (ANOVA). Se obtuvieron asociaciones estadísticamente significativas entre la presencia de problemas comportamentales y las condiciones socioeconómicas de la familia: a mayor vulnerabilidad socioeconómica y educativa, mayor deterioro en la salud mental infantil. Este estudio se encontró con la dificultad de las restricciones sanitarias por la pandemia de COVID-19 para continuar el trabajo de campo. Interesa replicar el estudio y considerar el impacto de la pandemia y el presunto deterioro de las variables sociodemográficas. Se debe priorizar la continuidad de una indagación sostenida para un seguimiento de la salud mental infantil.
Abstract This article shows the results of an empirical research study on behavioral and emotional problems in schoolchildren between 6 and 11 years old. From an epidemiological perspective the goal is to describe the behavioral problems of a clinical sample (N= 395, age: . = 7.92 y SD = 1.75) and a non-clinical sample (N = 363, age: M = 8.78 años y DE = 1.73). The specific objectives are to analyze the differences by sex and possible sociodemographic variables in both clinical and non-clinical contexts. A comparative study between both samples is not carried out. We administered the Child Behavior Checklist (CBCL) and a sociodemographic survey to the responsible adults. The quantitative analysis was carried out through studies of frequency, distribution and associations among variables in order to describe both samples from the point of view of the CBCL results and of the sociodemographic variables. In order to identify the possible sociodemographic conditioning factors in the childhood and youth psychopathology, we studied the associations among the CBCL syndrome scale scores and the different sociodemographic variables through the analysis of variance (ANOVA). The results of the clinical sample show mental health deterioration in boys and girls compared to previous studies. The increase of the internalizing and externalizing syndrome scores is significant. The prejudices and gender stereotypes constitute obstacles to gain access to mental health services in childhood, especially for girls whose psychological conditions may often go unnoticed. In the non-clinical sample, the gender distribution is even and the total average of average scores is lower compared to studies performed in other populations in previous years. In both samples we observe a significant relation between the psychological and behavioral problems and the socio-economic conditions of the family. The higher the educational and socio-economic vulnerability, the higher the deterioration of the children's mental health. The simultaneous study from the epidemiological perspective in both samples is necessary to detect psychopathological problems in childhood. This study encountered some limitations: the difficulty to continue the field work due to sanitary restrictions because of the COVID-19 pandemic. We want to replicate the study in both samples considering the impact of the pandemic and the alleged deterioration of the sociodemographic variables and family conditions. Another limitation has been the socio-economic homogeneity of the clinical sample. It would be useful in the future to include clinical samples that belong to other socioeconomic sectors who receive mental health care from private medical insurances or medical insurances run by labor unions. The shortage of epidemiological studies on emotional and behavioral problems in children and the lack of research work on the right to receive mental health care in childhood, indicate the absence of this topic in the political agenda. This deficit prevents the implementation of efficient programs to prevent and early detect mental health problems in children, to extend clinical care proposals in the community and to train professionals so that the programs can have an accurate impact on the population. It is a priority to continue the sustained inquiry in both populations in order to ensure the follow-up of the mental health conditions. Also, it would be useful to extend and deepen the analysis incorporating the examination of other family problems such as violence situations, consumption of psychoactive drugs, suicides and other loss situation.
RESUMO
Las fisuras orofaciales representan un grupo heterogéneo de malformaciones congénitas que afectan a distintas estructuras de la cavidad oral y de la cara. Globalmente, los bebés con estos trastornos presentan una mayor morbilidad y mortalidad a lo largo de su vida en comparación con individuos no afectados. Por ello, los avances en la investigación biomédica resultan ineludibles. Así, el objetivo general de este trabajo fue llevar a cabo una revisión bibliográfica para analizar narrativamente los 10 principales estudios primarios sobre fisuras orofaciales llevados a cabo en España, publicados del 2018 hasta la actualidad. Según esto, a nivel institucional, destaca la Universidad Complutense de Madrid (UCM) con cuatro artículos publicados por el grupo de investigación UCM 920202. También sobresale la Universidad Rey Juan Carlos de Madrid, con tres artículos relacionados con diferentes aspectos de la personalidad y la calidad de vida de los pacientes fisurados, así como otras muchas variables cognitivo-emocionales. En relación con la Universidad de Valencia, encontramos dos artículos llevados a cabo en amplias muestras de pacientes con fisuras. Por último, en Barcelona resulta destacable un estudio observacional sobre problemas otorrinolaringológicos en pacientes operados de fisura palatina. En conclusión, si bien en los últimos años se han publicado varios artículos sobre distintos aspectos relacionados con las fisuras, aún queda mucho trabajo por hacer. España debería seguir potenciando proyectos con líneas de trabajo centradas en estas alteraciones del desarrollo craneofacial. Se necesitan estudios amplios, multicéntricos y colaborativos, para ahondar en los mecanismos etiológicos y, en última instancia, en las posibles herramientas para su prevención. Del mismo modo, se necesitan ayudas para dilucidar mejor las cuestiones relacionadas con los tratamientos en todas las dimensiones de la salud, preferentemente a partir de ensayos clínicos controlados aleatorizados, que faciliten la traslación de conocimientos y su accesibilidad universal dentro del sistema sanitario público español.
SUMMARY: Orofacial clefts represent a heterogeneous group of congenital malformations affecting different structures of the oral cavity and face. Overall, infants with these disorders have a higher lifetime morbidity and mortality compared to unaffected individuals. Therefore, advances in biomedical research are unavoidable. Thus, the overall objective of this work was to conduct a literature review to narratively analyse the 10 main primary studies on orofacial clefts carried out in Spain, published from 2018 to date. According to this review, at an institutional level, the Complutense University of Madrid (UCM) is notable with 4 articles published by the UCM 920202 research group. The Rey Juan Carlos University of Madrid also stands out, with three papers related to different aspects of the personality and quality of life of cleft patients, as well as many other cognitive-emotional variables. In relation to the University of Valencia, we found two studies carried out on large samples of cleft patients. Finally, in Barcelona, an observational study on otorhinolaryngological problems in cleft palate patients is noteworthy. In conclusion, although several studies have been published in recent years on different aspects related to clefts, there is still much work to be done. Spain should craniofacial development. Large, multicenter and collaborative studies are needed to delve deeper into the aetiological mechanisms and, ultimately, into the possible tools for their prevention. Similarly, support is needed to better elucidate questions related to treatments in all dimensions of health, preferably randomised controlled clinical trials, which facilitate the transfer of knowledge and its universal accessibility within the Spanish public health system.

SUMMARY Obesity is a chronic disease characterized by excess fat in the body and a real public health problem. Bariatric surgery, in recent decades, has gained space in its treatment due to the efficiency obtained in weight loss and significant reduction of the related comorbidities. The most commonly performed bariatric procedures include Roux-en-Y gastric bypass, adjustable gastric band, and laparoscopic sleeve gastrectomy. Possible complications described include fistulas, dehiscence, marginal ulcers, intestinal obstruction, internal hernias, and anastomotic stenosis. These complications may have unfavorable clinical outcomes since symptoms are often nonspecific. Abdominal computed tomography (CT) is an important tool in the evaluation of postoperative complications, both in the immediate and late postoperative status of patients undergoing such a procedure. We analyzed the most illustrative tomographic findings of the different complications after reducing gastroplasty in 203 patients without distinction of age or gender. Correct interpretation requires radiologists to understand the surgical technique since postoperative anatomy and surgery-specific complications may be obstacles to proper interpretation.
RESUMO A obesidade é uma doença crônica caracterizada pelo excesso de tecido adiposo no organismo e um verdadeiro problema de saúde pública. A cirurgia bariátrica, nas últimas décadas, ganhou espaço no seu tratamento devido à eficiência obtida na perda ponderal e redução importante de comorbidades relacionadas. Os procedimentos bariátricos mais comumente realizados incluem o bypass gástrico em Y-de-Roux, a banda gástrica ajustável e a gastrectomia vertical — Sleeve — por via laparoscópica. Entre as complicações possíveis descritas podem ser citadas: fístulas, deiscências, úlceras marginais, obstrução intestinal, hérnias internas e estenose de anastomoses. Essas complicações podem apresentar desfechos clínicos desfavoráveis, uma vez que os sintomas são frequentemente inespecíficos. A tomografia computadorizada de abdome (TC) constitui uma importante ferramenta na avaliação de complicações pós-operatórias, tanto no status pós-cirúrgico imediato quanto tardias, de pacientes submetidos a tal procedimento. Foram analisados os achados tomográficos mais ilustrativos das diferentes complicações pós-gastroplastia redutora ocorridas em 203 pacientes sem distinção de idade ou gênero. A correta interpretação requer que os radiologistas compreendam a técnica cirúrgica, uma vez que a anatomia pós-cirúrgica e as complicações específicas da cirurgia podem ser obstáculos para a adequada interpretação.

Apesar da melhora no diagnóstico e tratamento, a gravidez ectópica ainda é a principal causa de mortalidade materna no primeiro trimestre da gravidez. Formas raras podem apresentar um desafio diagnóstico e, sem um diagnóstico adequado, a incidência de complicações e a mortalidade materna estão relacionadas a aumento de seus índices. Os termos "gravidez cornual" e "gravidez intersticial" têm sido utilizados de forma inconsistente na literatura, sendo frequentemente usados como sinônimos do termo "gravidez angular". Uma distinção estrita entre essas entidades pode ter implicações clínicas importantes, porque o curso natural, a propedêutica e os resultados diferem entre eles. A ressonância magnética não é o padrão-ouro para o diagnóstico de gravidez ectópica, no entanto possui relevância significativa no diagnóstico de possíveis complicações decorrentes dessa afecção. Nesse contexto, esta revisão aborda a importância da ressonância magnética na distinção dos tipos de gravidez mencionados, ilustrados por meio de casos do nosso serviço.(AU)
Despite the improvement in diagnostics and treatment, ectopic pregnancies are still the main cause of maternal mortality in the first trimester of pregnancy. Rare forms may present a diagnostic challenge and without adequate diagnosis, the incidence of complications and maternal mortality is greatly increased. The terms "cornual pregnancy" and "interstitial pregnancy" have been used inconsistently in the literature, frequently been used as synonyms and even used interchangeably with the term "angular pregnancy". A strict distinction among these entities can have important clinical implications because the natural course, management and outcomes differ among them. Magnetic resonance imaging is not the gold standard for the diagnosis of ectopic pregnancy, however, it can be useful in the diagnosis of complicated presentations of such ailment. In this context, this review highlights the importance of MRI in distinguishing the aforementioned types of pregnancies, illustrated with few cases from our service.(AU)

Abstract Objective: To compare automated and manual magnetic resonance imaging protocols for estimating liver iron concentrations at 1.5 T. Materials and Methods: Magnetic resonance imaging examination of the liver was performed in 53 patients with clinically suspected hepatic iron overload and in 21 control subjects. Liver iron concentrations were then estimated by two examiners who were blinded to the groups. The examiners employed automated T2* and T1 mapping, as well as manual T2* and signal-intensity-ratio method. We analyzed accuracy by using ROC curves. Interobserver and intraobserver agreement were analyzed by calculating two-way intraclass correlation coefficients. Results: The area under the ROC curve (to discriminate between patients and controls) was 0.912 for automated T2* mapping, 0.934 for the signal-intensity-ratio method, 0.908 for manual T2*, and 0.80 for T1 mapping, the last method differing significantly from the other three. The level of interobserver and intraobserver agreement was good (intraclass correlation coefficient, 0.938-0.998; p < 0.05). Correlations involving T1 mapping, although still significant, were lower. Conclusion: At 1.5 T, T2* mapping is a rapid tool that shows promise for the diagnosis of liver iron overload, whereas T1 mapping shows less accuracy. The performance of T1 mapping is poorer than is that of T2* methods.
Resumo Objetivo: Comparar protocolos automatizados e manuais de ressonância magnética para estimar a concentração hepática de ferro em 1,5 T. Materiais e Métodos: Foi realizada ressonância magnética hepática em 53 pacientes com suspeita de sobrecarga de ferro hepática e 21 controles, seguida da estimativa cega da concentração hepática de ferro por dois examinadores usando mapas automáticos T2* e T1, assim como o manual T2* e o método signal-intensity-ratio. O desempenho foi medido usando curvas ROC e a correlação interobservador e intraobservador usando o coeficiente de correlação intraclasse bidirecional. Resultados: O desempenho da curva ROC separando pacientes e controles mostrou áreas sob a curva de 0,912 para o mapa automático T2*, 0,934 para o método signal-intensity-ratio, 0,908 para manual T2* e 0,80 para mapa T1 (este difere significativamente dos outros três métodos). Houve boa correlação interobservador e intraobservador (coeficiente de correlação intraclasse entre 0,938 e 0,998; p < 0,05). Correlações envolvendo o mapa T1, embora ainda significativas, foram menores. Conclusão: Em 1,5 T, o mapa T2* representa uma nova ferramenta rápida e promissora para avaliar o diagnóstico de sobrecarga de ferro hepática, enquanto o mapa T1 mostrou menor precisão. O desempenho do mapa T1 foi menor que o dos métodos T2*.
RESUMO
Abstract The rupture of an abdominal aortic aneurysm (AAA) is considered a high-risk surgical emergency, given the catastrophic consequences and high mortality rate. The objective of this pictorial essay is to illustrate the radiological signs that indicate rupture or imminent rupture. To that end, we describe cases treated at our facility and present a brief review of the literature on the topic. The clinical diagnosis of imminent AAA rupture can be difficult, because patients are usually asymptomatic or have nonspecific pain complaints. In the subsequent follow-up, it is possible to identify radiological signs that indicate instability or rupture itself and thus change the prognosis. Computed tomography is the modality of choice for evaluating an AAA and abdominal pain in the emergency setting. It is therefore essential that the radiologist immediately identify the imaging findings that indicate AAA rupture or the imminent risk of such rupture.
Resumo A ruptura de aneurisma da aorta abdominal (AAA) é considerada uma emergência cirúrgica de altíssimo risco, pelas consequências catastróficas e pelo alto índice de mortalidade. Este ensaio iconográfico tem como objetivo ilustrar os sinais radiológicos que indiquem ruptura ou a sua iminência. Utilizamos casos atendidos no nosso serviço e apresentamos breve revisão bibliográfica acerca do tema. O diagnóstico clínico da iminência de ruptura de AAA pode ser difícil, visto que os pacientes são normalmente assintomáticos ou apresentam queixas álgicas inespecíficas. No controle evolutivo, podem ser identificados sinais radiológicos que indiquem instabilidade ou a própria ruptura e, dessa forma, mudar o prognóstico do paciente. Como a tomografia computadorizada é a modalidade de escolha para a avaliação dos AAAs e da dor abdominal no cenário da emergência, torna-se imprescindível o reconhecimento precoce pelo radiologista dos achados de imagem que indiquem aneurismas rotos ou com risco iminente de ruptura.
RESUMO
Common bean is a crop recalcitrant to in vitro regeneration and therefore it lacks an efficient transformation protocol that can be reproduced using A. tumefaciens. The main goal of this study was to establish a protocol for A. tumefaciens mediated transformation of Phaseolus vulgaris var. Brunca by marker genes (gusA and nptII) together with the gene for trehalose-6-phosphate synthase from Saccharomyces cerevisiae (TPS1) used in other species to increase tolerance to abiotic stress. The β-glucuronidase activity was detected in 45 % of the LBA4404 ElectroMAX® pCAMBIA1301 infected explants. Transformed explants regenerated new shoots after four to five months period in a kanamycin rich media. Surviving plants were evaluated by PCR and presented an 0.5 % efficiency of transformation. The established protocol for genetic transformation of common bean has two additional advantages with respect to previous reports: (1) it allows for obtaining transformed regenerants and (2) the genetic transformation was stable for the selective gene.
El frijol común en un cultivo recalcitrante a la regeneración in vitro y se carece de un protocolo eficiente y reproducible de transformación genética usando A. tumefaciens. Desarrollamos un protocolo de transformación genética mediada por A. tumefaciens de frijol común variedad Brunca utilizando genes marcadores (gusA y nptII) junto con el gen de la trehalosa-6-fosfato sintasa de levadura (TPS1) utilizado para incrementar tolerancia a estrés abiótico. La actividad de la β-glucoronidasa fue detectada en 45 % de los explantes infectados con la cepa LBA4404 de A. tumefaciens transformada con pCAMBIA1301. Después de 4 o 5 meses se regeneraron tallos en un medio adicionado con kanamicina. Los explantes supervivientes se evaluaron mediante PCR y presentaron una eficiencia de transformación de 0.5 %. El protocolo de transformación genética de frijol común establecido tiene dos ventajas adicionales con respecto a los reportes previos: (1) permite la obtención de regenerares transformados y (2) la transformación genética fue estable para el gen selectivo.
