Projeto e validação de um questionário de saúde oral para avaliação pré‐anestésica no pré‐operatório

BACKGROUND AND OBJECTIVES: Dental injuries incurred during endotracheal intubation are more frequent in patients with previous oral pathology. The study objectives were to develop an oral health questionnaire for preanaesthesia evaluation, easy to apply for personnel without special dental training; and establish a cut-off value for detecting persons with poor oral health. METHODS: Validation study of a self-administered questionnaire, designed according to a literature review and an expert group's recommendations. The questionnaire was applied to a sample of patients evaluated in a preanaesthesia consultation. Rasch analysis of the questionnaire psychometric properties included viability, acceptability, content validity and reliability of the scale. RESULTS: The sample included 115 individuals, 50.4% of men, with a median age of 58 years (range: 38-71). The final analysis of 11 items presented a Person Separation Index of 0.861 and good adjustment of data to the Rasch model. The scale was unidimensional and its items were not biased by sex, age or nationality. The oral health linear measure presented good construct validity. The cut-off value was set at 52 points. CONCLUSIONS: The questionnaire showed sufficient psychometric properties to be considered a reliable tool, valid for measuring the state of oral health in preoperative anaesthetic evaluations.S

Incidence and risk factors of cisplatin-induced ototoxicity

Introduction and objectives: Cisplatin is one of the drugs with greater ototoxicity within clinical use. Hearing loss detection and therapeutic measures can be done in early stages by controlling the auditory thresholds of patients on treatment. With this paper we intend to assess the incidence and severity of hearing loss by cisplatin in our environment, identifying major risk factors./nMethods: The case study was conducted on a third level hospital by monitoring and recording the hearing loss by cisplatin among the first 100 patients who accepted the audiologic monitoring. Those patients were sent by the oncology department. Then a high frequency audiometry and the otoacoustic emissions was carried out on the patients to evaluate them./nResults: Essentially, we refer to a group which us made up of adults with an average age of 59 years old. Out of the 70 patients treated only with cisplatin, 27% experienced hearing loss. Among the remaining 30 patients who received radiotherapy in addition to cisplatin, hearing impairment at 53% was detected. Cisplatin ototoxic effects are dose-dependent and more intense with normal hearing. In our results, gender, age or the presence of previous hearing loss, were not statistically significant factors in vulnerability./nConclusions: the susceptibility variable to ototoxic damage on patients, the clinically insidious onset of hearing loss and its irreversibility, justify the need to monitor the cisplatin ototoxicity. Clinical data allow us to calculate the risk of an average population, although it does not help to predict what will happen to each patient.Introducción y objetivos: El cisplatino es uno de los fármacos de uso clínico con mayor ototoxicidad. Controlando los umbrales auditivos de los pacientes en tratamiento, podemos realizar una detección precoz de la hipoacusia y adoptar medidas terapéuticas. Con este trabajo pretendemos evaluar la incidencia y severidad de la hipoacusia por cisplatino en nuestro medio, identificando los principales factores de riesgo. /nMétodos: Monitorización y registro, en un hospital de tercer nivel, de la pérdida auditiva por cisplatino, en los primeros 100 pacientes enviados por oncología que aceptan el seguimiento audiológico, aplicando la audiometría de alta frecuencia y las otoemisiones acústicas./nResultados: Se trata de una población fundamentalmente adulta, con una edad media de 59 años. De los 70 pacientes tratados sólo con cisplatino un 27% manifestó la aparición o el incremento de su hipoacusia. En los 30 restantes, que además de cisplatino recibieron radioterapia, detectamos afectación auditiva en el 53%. Los efectos ototóxicos del cisplatino son dosis dependiente y más intensos con audición normal. En nuestros resultados, ni el género, ni la edad, ni la presencia de hipoacusia previa, fueron factores estadísticamente significativos en la vulnerabilidad./nConclusiones: La susceptibilidad variable al daño ototóxico, el inicio clínicamente insidioso y su irreversibilidad, justifican la conveniencia de monitorizar la ototoxicidad por cisplatino. Los datos clínicos nos permiten calcular el riesgo medio de una población, aunque no sirvan para predecir lo que le ocurrirá a un paciente en concreto

Pleosporales

One hundred and five generic types of Pleosporales are described and illustrated. A brief introduction and detailed history with short notes on morphology, molecular phylogeny as well as a general conclusion of each genus are provided. For those genera where the type or a representative specimen is unavailable, a brief note is given. Altogether 174 genera of Pleosporales are treated. Phaeotrichaceae as well as Kriegeriella, Zeuctomorpha and Muroia are excluded from Pleosporales. Based on the multigene phylogenetic analysis, the suborder Massarineae is emended to accommodate five families, viz. Lentitheciaceae, Massarinaceae, Montagnulaceae, Morosphaeriaceae and Trematosphaeriaceae

Proteomic Insights into the Hidden World of Phloem Sap Feeding

The physical interface between a phloem-feeding insect and its host plant is a single cell buried deep within the plant tissue. As such, the molecular interactions between these notorious agricultural pests and the crop plants upon which they feed are diffi cult to study. ‘Omic’ technologies have proved crucial in revealing some of the fascinating detail of the molecular interplay between these partners. Here we review the role of proteomics in identifying putative components of the secreted saliva of phloem-feeding insects, particularly aphids, and discuss the limited knowledge concerning the function of these proteins

Risk factors, complications and survival after upper abdominal surgery:a prospective cohort study

Background: Preoperative weight loss and abnormal serum-albumin have traditionally been associated with reduced survival. More recently, a correlation between postoperative complications and reduced long-term survival has been reported and the significance of the relative proportion of skeletal muscle, visceral and subcutaneous adipose tissue has been examined with conflicting results. We investigated how preoperative body composition and major non-fatal complications related to overall survival and compared this to established predictors in a large cohort undergoing upper abdominal surgery. Methods: From 2001 to 2006, 447 patients were included in a Norwegian multicenter randomized controlled trial in major upper abdominal surgery. Patients were now, six years later, analyzed as a single prospective cohort and overall survival was retrieved from the National Population Registry. Body composition indices were calculated from CT images taken within three months preoperatively. Results: Preoperative serum-albumin 5 % (HR = 1.38, p = 0.023) were independently associated with reduced survival. There was no association between any of the preoperative body composition indices and reduced survival. Major postoperative complications were independently associated with reduced survival but only as long as patients who died within 90 days were included in the analysis. Conclusions: Our study has confirmed the robust significance of the traditional indicators, preoperative serum-albumin and weight loss. The body composition indices did not prove beneficial as global indicators of poor prognosis in upper abdominal surgery. We found no association between non-fatal postoperative complications and long-term survival
