We describe a case of probable sporadic Creutzfeldt–Jakob disease in the setting of well-controlled HIV and discuss whether exist, in fact, HIV-related factors that may predispose to the development of prion disease. To the best of our knowledge, this is the third report of this association.
Background/AimsEvaluation of esophageal clearance by orange juice swallowing could be useful to identify different categories of gastroesophageal reflux disease. We determined whether a juice test at the beginning of esophageal pH monitoring can identify nonerosive reflux disease (NERD) among heartburn patients.MethodsMultiple swallows of orange juice (pH 3) were performed at the beginning of esophageal pH monitoring in 71 heartburn patients off acid-suppressive therapy. The area between pH drop below 5 and recovery to 5 was calculated from pH tracings and named Delta5 (mmol·L−1·sec). Fifteen healthy subjects served to determine Delta5 cutoff (95th percentile). Patients were classified as NERD, non-NERD (a mix of reflux hypersensitivity, functional heartburn, and undetermined), and erosive disease depending on acid exposure, reflux symptom analysis, and upper endoscopy.ResultsDelta5 cutoff in healthy subjects was 251 mmol·L−1·sec. Among 71 patients, 23 had NERD, 26 had non-NERD, and 22 had erosive disease. Compared to non-NERD, Delta5 was higher in both NERD (median [interquartile range]: 316 [213–472] vs 165 [105–225]; P < 0.01) and erosive disease (310 [169–625] vs 165 [105–225]; P < 0.01). An elevated Delta5 (> 251 mmol·L−1·sec) showed sensitivity of 74% and specificity of 81% for identification of NERD. Positive and negative likelihood ratios were 3.84 and 0.32 respectively, whereas test accuracy was 78%.ConclusionsA juice test with calculation of Delta5 helps in the identification of true NERD among heartburn patients with endoscopy-negative reflux disease. In these patients, an elevated Delta5 could make prolonged reflux testing unnecessary.
Neste artigo, aborda-se a temática da ética em pesquisa especificamente no campo da Aquisição da Linguagem. O enfoque objetiva refletir sobre a constituição do pesquisador na área aquisicional levando em conta a singularidade do trabalho com a criança e, ainda, discutir as escolhas que permeiam o processo de transcrição de registros em áudio e/ou vídeo produzidos em pesquisas de campo. Para dar conta de tal reflexão, mobilizam-se, principalmente, princípios teóricos da obra “Para uma filosofia do ato responsável”, de Bakhtin (2020), na qual o autor propõe um modo particular de se pensar a pesquisa em Ciências Humanas partindo da realidade do ato. Dessa forma, os conceitos bakhtinianos de ato responsável, pensamento participativo, centro de valores, não-álibi e assinatura fundamentam este artigo. O estudo configura-se como um ensaio teórico reflexivo. Ademais, estudiosos de Bakhtin e pesquisadores da área da Aquisição, tal como Sobral (2019) e Del Ré, Paula e Mendonça (2014), complementam e amparam tal interlocução teórica. Por fim, conclui-se que o ato responsável de pesquisar pressupõe um pensamento participativo do pesquisador e uma tensão de vozes entre pesquisador/pesquisado, além disso a transcrição reflete as demais escolhas da pesquisa, uma vez que é transpassada pela orientação valorativa do pesquisador como centro do fazer científico.
