Percepciones y posiciones sobre la eutanasia, en médicos y enfermeras, de 5 hospitales de Santo Domingo, durante el período septiembre - noviembre de 2001

La eutanasia es la aceleración del proceso de morir en pacientes terminales mediante su solicitud. Las condiciones para esta practica son: que el paciente se encuentre competente, que su solicitud sea sin presión, que tenga enfermedad irreversible y que el medico que proceda, consulte otras fuentes para asegurar las causas de tal determinación. En ocasiones de eutanasia, es cuando medicos y/o enfermeras, tienen en sus manos casos a tratarse mediante la bioetica. Esta investigación fue hecha de manera analíticaprospectiva para determinar percepciones y posiciones sobre la eutanasia, en medicos y enfermeras, de 5 hospitales de Santo Domingo, durante Septiembre-Noviembre de 2001. Nuestro objetivo es conocer y valorar las opiniones de los entrevistados. Utilizamos un cuestionario para ser aplicado a 25 medicos y 25 enfermeras. De los 25 medicos, resultó que todos sabían el concepto de eutanasia pero al momento de definir en que consistía resultó que sólo 9 (3ó% ), sabían correctamente su significado. En tanto que las enfermeras, tambien decían conocer la eutanasia pero al momento de definirla sólo 2 (8%), dieron la respuesta correcta. Esto nos lleva a la conclusion de que el personal de salud que labora en nuestros hospitales tiene una errada concepción de eutanasia lo que puede llevar a practicas y conclusiones equivocadas. Delos medicos, el 64% dijo estar de acuerdo con practicarla junta con el 24% de las enfermeras, pero de acuerdo a la definición que ellos dieron ¿de que eutanasia estarían ellos hablando?, ¿Muerte por compasión o ayudar a morir

Severe COVID-19 Illness and α1-Antitrypsin Deficiency: COVID-AATD Study

Background: Epidemiologic studies have reported that the geographical distribution of the prevalence of allelic variants of serine protein inhibitor-A1 (SERPINA1) and severe cases of COVID-19 were similar. Methods: A multicenter, cross-sectional, observational study to evaluate the frequency of alpha-1 antitrypsin deficiency (AATD) in patients with COVID-19 and whether it was associated with having suffered severe COVID-19. Results: 2022 patients who had laboratory-confirmed SARS-CoV-2 infection. Mutations associated with AATD were more frequent in severe COVID versus non-severe (23% vs. 18.8%, p = 0.022). The frequency of Pi*Z was 37.8/1000 in severe COVID versus 17.5/1000 in non-severe, p = 0.001. Having an A1AT level below 116 was more frequent in severe COVID versus non-severe (29.5% vs. 23.1, p = 0.003). Factors associated with a higher likelihood of severe COVID-19 were being male, older, smoking, age-associated comorbidities, and having an A1AT level below 116 mg/dL [OR 1.398, p = 0.003], and a variant of the SERPINA1 gene that could affect A1AT protein [OR 1.294, p = 0.022]. Conclusions: These observations suggest that patients with AATD should be considered at a higher risk of developing severe COVID-19. Further studies are needed on the role of A1AT in the prognosis of SARS-CoV-2 infection and its possible therapeutic role

Differences in Drug-Susceptibility Patterns between <i>Mycobacterium avium</i>, <i>Mycobacterium intracellulare</i>, and <i>Mycobacterium chimaera</i> Clinical Isolates: Prospective 8.5-Year Analysis by Three Laboratories

Background: It has been suggested that Mycobacterium avium, Mycobacterium intracellulare, and M. chimaera have differential drug susceptibility patterns. We prospectively analyzed and compared the drug susceptibility patterns among these species over an 8.5-year period. Methods: A microdilution method (Slomyco®) was performed for drug susceptibility testing of 402 M. avium, 273 M. intracellulare, and 139 M. chimaera clinical isolates. Results: M. avium showed significantly higher resistance to moxifloxacin, ciprofloxacin, rifampicin, ethambutol, streptomycin, linezolid, cotrimoxazole, and clarithromycin. M. avium also showed higher minimum inhibitory concentrations (MIC) than M. intracellulare and M. chimaera against all drugs except ethionamide, to which M. intracellulare and M. chimaera showed greater resistance. Conclusions: Our series demonstrated differential drug resistance patterns among the most frequent M. avium complex species. M. avium was more resistant than M. intracellulare and M. chimaera versus eight antibiotics and showed greater MIC values to most of the antibiotics studied. These data suggest that knowledge of the local distribution and susceptibility profiles of these pathogens is essential for adequate clinical management

Immunofluorescence Analysis as a Diagnostic Tool in a Spanish Cohort of Patients with Suspected Primary Ciliary Dyskinesia

Primary ciliary dyskinesia (PCD) is an autosomal recessive rare disease caused by an alteration of ciliary structure. Immunofluorescence, consisting in the detection of the presence and distribution of cilia proteins in human respiratory cells by fluorescence, has been recently proposed as a technique to improve understanding of disease-causing genes and diagnosis rate in PCD. The objective of this study is to determine the accuracy of a panel of four fluorescently labeled antibodies (DNAH5, DNALI1, GAS8 and RSPH4A or RSPH9) as a PCD diagnostic tool in the absence of transmission electron microscopy analysis. The panel was tested in nasal brushing samples of 74 patients with clinical suspicion of PCD. Sixty-eight (91.9%) patients were evaluable for all tested antibodies. Thirty-three cases (44.6%) presented an absence or mislocation of protein in the ciliary axoneme (15 absent and 3 proximal distribution of DNAH5 in the ciliary axoneme, 3 absent DNAH5 and DNALI1, 7 absent DNALI1 and cytoplasmatic localization of GAS8, 1 absent GAS8, 3 absent RSPH9 and 1 absent RSPH4A). Fifteen patients had confirmed or highly likely PCD but normal immunofluorescence results (68.8% sensitivity and 100% specificity). In conclusion, immunofluorescence analysis is a quick, available, low-cost and reliable diagnostic test for PCD, althouh it cannot be used as a standalone tes

Implementation of a Gene Panel for Genetic Diagnosis of Primary Ciliary Dyskinesia

Introduction: Primary ciliary dyskinesia (PCD) is characterized by an alteration in the ciliary structure causing difficulty in the clearance of respiratory secretions. Diagnosis is complex and based on a combination of techniques. The objective of this study was to design a gene panel including all known causative genes, and to corroborate their diagnostic utility in a cohort of Spanish patients. Methods: This was a multicenter cross-sectional study of patients with a high suspicion of PCD, according to European Respiratory Society criteria, designed around a gene panel for massive sequencing using SeqCap EZ capture technology that included 44 genes associated with PCD. Results: We included 79 patients, 53 of whom had a diagnosis of confirmed or highly probable PCD. The sensitivity of the gene panel was 81.1%, with a specificity of 100%. Candidate variants were found in some of the genes of the panel in 43 patients with PCD, 51.2% (22/43) of whom were homozygotes and 48.8% (21/43) compound heterozygotes. The most common causative genes were DNAH5 and CCDC39. We found 52 different variants, 36 of which were not previously described in the literature. Conclusions: The design and implementation of a tailored gene panel produces a high yield in the genetic diagnosis of PCD. This panel provides a better understanding of the causative factors involved in these patients and lays down the groundwork for future therapeutic approaches
