Patient experience and non-surgical periodontal therapy in a postgraduate periodontal training program: A qualitative study

ABSTRACT: Objective: To explore patient experience for non-surgical periodontal therapy using phenomenography. Methods: This qualitative study was performed in a postgraduate specialist training program in periodontics. Patients reported their experiences through in-depth interviews in order to recognize the impact of non-surgical periodontal therapy on their quality of life and their satisfaction. A homogeneous sampling procedure was used, establishing redundancy after the fifteenth interview. Interviews were audio recorded, transcribed and analyzed by three researchers who codified the answers into categories to determine the emerging topics. Results: The core emerging themes were: (i) lack of information about periodontal disease; (ii) experience during treatment; (iii) treatment implications; and (iv) clinician-patient relationship. Conclusions: Patients seem to have limited knowledge about periodontal diseases. Reasons for attendance mainly include bleeding gums, tooth mobility, and aesthetic problems. Therapy can generate pain, fear, and is considered invasive, whereas dentine hypersensitivity may occur post-operatively. Despite this, patients would be willing to undergo treatment again and were generally satisfied with the level of care and treatment received.

Pró-Fármacos dendriméricos potencialmente ativos em Malária e Tuberculose: Síntese e avaliação da atividade biológica / Dendrimeric prodrugs potentially active in malaria and tuberculosis: Synthesis and evaluation of biological activity

HIV/AIDS, tuberculose, malária e as doenças tropicais negligenciadas representam uma grande preocupação em Saúde em muitas regiões do mundo. Os fármacos disponíveis para o tratamento apresentam diversos problemas, tais como toxicidade e resistência ao parasita. Mesmo com esse triste panorama, o investimento em pesquisa nessa área é, ainda, pouco significativo. Assim, dentre os métodos de modificação molecular para melhorar propriedades farmacêuticas, farmacocinéticas e/ou farmacodinâmica de compostos bioativos destaca-se a latenciação. Já os dendrímeros vêm despertando interesse em aplicações biológicas, principalmente como transportadores de fármacos, além de atuarem como transportadores de genes, imagem em diagnóstico e compostos com ação per se. Face ao exposto e tendo em vista o caráter promissor dos dendrímeros como sistemas de drug delivery, o objetivo deste trabalho foi a síntese de pró-fármacos dendriméricos potencialmente ativos em malária e tuberculose. Os dendrímeros de Bis-MPA (gerações 0, 1 e 2) foram sintetizados pelo grupo do Professor Scott Grayson, da Tulane University (EUA). No Brasil, foram feitas as funcionalizações destes compostos, através do acoplamento do ácido succínico (que funciona como espaçante) e as moléculas ativas. Selecionaram-se as seguintes substâncias: (1) primaquina, com ação antimalárica e (2) isoniazida, de ação nos primeiros estágios da tuberculose. Foram sintetizados os pró-fármacos dendriméricos de isoniazida nas gerações 0 e 1 (G0-Iso e G1-Iso), e primaquina nas gerações 0, 1 e 2 (G0-Pq, G1-Pq e G2Pq). Importante mencionar que os resultados de Ressonância Magnética e Nuclear de 1H e de 13C demostraram as obtenções dos respectivos produtos, porém contendo impurezas. Já a análise do resultado proveniente da espectrometria de massas do composto G0-Iso revelou a presença de um subproduto ciclizado da isonizaida succinoilada (CIso-Suc), o qual pode ser um potencial pró-fármaco ou apresentar atividade per se. Como não se conhece este composto, o laboratório coordenado pela Profas Elizabeth Igne Ferreira e Jeanine Giarolla manifestou interesse em pesquisa-lo, principalmente quanto suas propriedades físico- químicas, bem como quanto à atividade biológica. Assim, utilizando metodologia analítica previamente estabelecida para o G0-Iso, os estudos de estabilidade química da CIso-Suc, em diferentes valores de pH, demonstraram a capacidade da forma ciclizada em se converter no protótipo Iso-Suc, majoritariamente em pH 7,4 e 8,5. Como perspectivas, destaca-se a avaliação da estabilidade enzimática deste potencial derivado. Ressalta-se, ainda, a a avaliação da respectiva atividade antimicobacteriana. Em relação aos pró-fármacos, as necessidades de aprimoramentos das sínteses são, também, evidenciadas. Uma vez sintetizados e caracterizados, estes últimos derivados serão avaliados quanto à atividade biológica. Ademais, estudos computacionais, sobretudo simulações de docking molecular, foram desenvolvidos com intuito de se entender o modo de interação de alguns compostos com alvos biológicos pré-determinados

HIV/AIDS, tuberculosis, malaria and neglected diseases are a major health concern in many regions of the world. The drugs available present various problems, such as toxicity and parasite resistance. Even with this sad outlook, research investment in this area is still insignificant. Among the molecular modification methods to improve the pharmaceutical, pharmacokinetic and/or pharmacodynamic properties we stands out prodrug design. On the other hand, dendrimers are arousing interest in biological applications, mainly as drug carriers, besides gene delivery, diagnostic imaging, as well as acting as compounds with activity per se. Considering that, added to the promising dendrimer drug delivery features, the aim of this study was to synthesize potentially active dendrimer prodrugs in malaria and tuberculosis. Bis-MPA dendrimers (generations 0, 1 and 2) were synthesized by the group of Professor Scott Grayson of Tulane University (USA). Herein in Brazil, the compounds were functionalized by coupling succinic acid (spacer group), as well as the active molecules. We selected the following substances: (1) primaquine, with antimalarial action and (2) isoniazid, acting in the early stages of tuberculosis. Isoniazid dendrimer prodrugs were synthesized generations 0 and 1 (G0-Iso and G1-Iso), and primaquine in generations 0, 1 and 2 (G0-Pq, G1-Pq and G2-Pq). It is important to mention that the results related to Nuclear and Magnetic Resonance 113C showed chemical structures features, however with impurities. Analysis of the mass spectrometry regarding G0-Iso has revealed the presence of a cyclized by-product of succinylated isonized (CIso-Suc), which may be a potential prodrug or may presentactivity itself. Using the analytical methodology performed for G0-Iso, ICso-Suc demonstrated its ability to convert the Iso-Suc prototype at different pH values, especially at pH 7.4 and 8.5. As perspectives, we highlight the determinations of the chemical stability of ICsoSuc at pH 1.5 and 6.0, as well as the evaluation of the enzymatic stability. We will also investigate the respective antimicobacterial activities. Regarding prodrugs, the needs for synthesis enhancements are also necessary. Once synthesized and characterized, these latter derivatives will be evaluated for biological activity. Moreover, computational studies, especially molecular docking simulations, were developed in order to understand the mode of interaction of some compounds with predetermined biological targets

Differences in hospitalization due to infectious causes between patients with hemodialysis and those with peritoneal dialysis / Diferencias en la hospitalización por causas infecciosas entre pacientes con hemodiálisis y diálisis peritoneal

Abstract Introduction: approximately 50% of the annual health care expenditure of patients with chronic kidney disease on dialysis is related to hospitalizations. Infections represent the second reason for consultation, with a high morbidity and mortality. There are no studies comparing hospitalization time due to infectious causes between the different dialysis options. Objective: to determine the difference in hospitalization time for treatment of infectious diseases in patients with chronic kidney disease on dialysis, comparing patients on hemodialysis vs. peritoneal dialysis. Materials and methods: a retrospective, dynamic cohort study of patients on hemodialysis and peritoneal dialysis who were admitted to the emergency department at the Hospital Universitario Mayor due to infectious diseases. The study patients were included using nonprobabilistic methods. The sample size was calculated by comparison of means. A total of 172 hemodialysis patients and 85 peritoneal dialysis patients were included for statistical analysis. Results: hospitalization time is greater in patients on hemodialysis than in patients on peritoneal dialysis; 12 (IQR 8-21) vs. 10 (IQR 6.5-13) days, respectively, p= 0.004. Conclusions: hospitalization time due to infectious causes is greater in patients on hemodialysis than in patients on peritoneal dialysis. In addition, the incidence of treatment-related infections in our population is lower than the globally reported incidence.(Acta Med Colomb 2020; 45. DOI:https://doi.org/10.36104/amc.2020.1222).

Resumen Introducción: aproximadamente el 50% del gasto anual en salud de los pacientes con enfermedad renal crónica en diálisis está relacionada con hospitalizaciones; las causas infecciosas representan la segunda causa de consulta con una alta morbilidad y mortalidad. No existen estudios donde se compare el tiempo de hospitalización por causas infecciosas entre las diferentes opciones de diálisis. Objetivo: determinar las diferencias en tiempos de hospitalización que se deriva del manejo de patologías infecciosas en pacientes con enfermedad renal crónica en diálisis, comparando los pacientes que se encuentran en hemodiálisis vs diálisis peritoneal. Material y métodos: estudio de cohorte retrospectiva, dinámica, de pacientes en hemodiálisis y diálisis peritoneal que ingresan al servicio de urgencias del Hospital Universitario Mayor por patologías infecciosas. Los pacientes que ingresaron al estudio se incluyeron por métodos no probabilísticos. El cálculo de tamaño de muestra se realizó por comparación de medias. Para el análisis estadístico se incluyeron 172 pacientes en hemodiálisis y 85 en diálisis peritoneal. Resultados: el tiempo de hospitalización es mayor en pacientes con hemodiálisis en comparación con los pacientes en diálisis peritoneal, 12 (RIC 8-21) vs 10 (RIC 6.5-13) días respectivamente, p= 0.004. Conclusiones: el tiempo de hospitalización por causas infecciosas es mayor en los pacientes con hemodiálisis que los de diálisis peritoneal, adicionalmente la incidencia de infecciones asociadas a la terapia en nuestra población es menor que lo reportado a nivel mundial.(Acta Med Colomb 2020; 45.
