    • A community randomised controlled trial evaluating a home-based environmental intervention package of improved stoves, solar water disinfection and kitchen sinks in rural Peru: Rationale, trial design and baseline findings

      Hartinger, S.M.; Lanata, Claudio F.; Hattendorf, J.; Gil, I.; Verastegui, H.; Ochoa, T.; Mäusezahl, D. (Elsevier B.V., 2015-03-24)
      Introduction: Pneumonia and diarrhoea are leading causes of death in children. There is a need to develop effective interventions. Objective: We present the design and baseline findings of a community-randomised controlled trial in rural Peru to evaluate the health impact of an Integrated Home-based Intervention Package in children aged 6 to 35 months. Methods: We randomised 51 communities. The intervention was developed through a community-participatory approach prior to the trial. They comprised the construction of improved stoves and kitchen sinks, the promotion of hand washing, and solar drinking water disinfection (SODIS). To reduce the potential impact of non-blinding bias, a psychomotor stimulation intervention was implemented in the control arm. The baseline survey included anthropometric and socio-economic characteristics. In a sub-sample we determined the level of faecal contamination of drinking water, hands and kitchen utensils and the prevalence of diarrhoegenic Escherichia coli in stool specimen. Results: We enrolled 534 children. At baseline all households used open fires and 77% had access to piped water supplies. E. coli was found in drinking water in 68% and 64% of the intervention and control households. Diarrhoegenic E. coli strains were isolated from 45/139 stool samples. The proportion of stunted children was 54%. Conclusions: Randomization resulted in comparable study arms. Recently, several critical reviews raised major concerns on the reliability of open health intervention trials, because of uncertain sustainability and non-blinding bias. In this regard, the presented trial featuring objective outcome measures, a simultaneous intervention in the control communities and a 12- month follow up period will provide valuable evidence.

      Acosta, J.; Flores, P.; Alarcón, M.; Grande-Ortiz, M.; Moreno-Exebio, L.; Puyen, Z. M. (International Union Against Tuberculosis and Lung Disease, 2022-01-01)
      BACKGROUND: Adherence to TB treatment and therefore treatment success could be improved using digital adherence technology. OBJECTIVE: To evaluate the effectiveness of a medication event reminder monitor system (MERM) on treatment success and treatment adherence in patients with drug-susceptible pulmonary TB in Perú. METHODS: This was an experimental, randomised, open-label, controlled study conducted among patients in the second phase of TB treatment. The intervention group received their medications through MERM with the support of a treatment monitor, whereas the control group used the usual strategy. Participants were followed until they completed the 54 doses of the second phase of treatment. RESULTS: The study included 53 patients in each group; four in the intervention group withdrew from the study. Treatment success was significantly more frequent in the MERM group (RR 1.15, 95% CI 1.02–1.30; P = 0.0322). There was no significant difference in the adherence outcomes; however, the percentage of patients who missed at least one dose and patients with more than 10% of total doses missed were lower in the intervention group. CONCLUSION: The use of MERM in the second phase of treatment showed a significant improvement in the treatment success rate in patients with drug-susceptible pulmonary TB.

      OBJECTIVES: The objective of this study was to perform a systematic review and meta-analysis of the literature to evaluate the efficacy and safety of therapies for cerebral toxoplasmosis in HIV-infected adults. The pyrimethamine plus sulfadiazine (P-S) combination is considered the mainstay therapy for cerebral toxoplasmosis and pyrimethamine plus clindamycin (P-C) is the most common alternative treatment. Although trimethoprim-sulfamethoxazole (TMP-SMX) has potential advantages, its use is infrequent. METHODS: We searched PubMed and four other databases to identify randomized controlled trials (RCTs) and cohort studies. Two independent reviewers searched the databases, identified studies and extracted data. Risk ratios (RRs) were pooled across studies using random-effects models. RESULTS: Nine studies were included (five RCTs, three retrospective cohort studies and one prospective cohort study). In comparison to P-S, treatment with P-C or TMP-SMX was associated with similar rates of partial or complete clinical response [P-C: RR 0.87; 95% confidence interval (CI) 0.70-1.08; TMP-SMX: RR 0.97; 95% CI 0.78-1.21], radiological response (P-C: RR 0.92; 95% CI 0.82-1.03), skin rash (P-C: RR 0.81; 95% CI 0.56-1.17; TMP-SMX: RR 0.17; 95% CI 0.02-1.29), gastrointestinal impairment (P-C: RR 5.16; 95% CI 0.66-40.11), and drug discontinuation because of adverse events (P-C: RR 0.32; 95% CI 0.07-1.47). Liver impairment was more frequent with P-S than P-C (P-C vs. P-S: RR 0.48; 95% CI 0.24-0.97). CONCLUSIONS: The current evidence fails to identify a superior regimen in terms of relative efficacy or safety for the treatment of HIV-associated cerebral toxoplasmosis. Use of TMP-SMX as preferred treatment may be consistent with the available evidence and other real-world considerations. Larger comparative studies are needed.
    • Acciones de prevención y control de la legionelosis: un reto para la salud pública española.

      Gea-Izquierdo, Enrique; Mezones-Holguín, Edward; Haro-García, Luis (Instituto Nacional de Salud (INS), 2014-03-20)
      La legionelosis es una enfermedad respiratoria con origen en sistemas que formen aerosol y que contenga el agente biológico Legionella sp. En las últimas décadas se ha desarrollado en España un marco normativo para su prevención y control. El presente artículo expone la epidemiología de la legionelosis y la importancia del control de la transmisión de la bacteria en la lucha contra la enfermedad. Para ello, se hace patente la revisión de las instalaciones críticas y la inclusión de otras nuevas en la legislación preventiva así como la estimación del riesgo, la mejora en los procesos de diagnóstico y el avance en nuevos protocolos de prevención.

    • Aceptabilidad del sabor de preparaciones hiposódicas con sustitutos de sal en pacientes diabéticos e hipertensos

      Ayerbe-Azabache, Angela; Calderón-Ramírez, Nancy; Taboada,Marco; Mayta-Tristan, Percy; [email protected] (2016-12)
      l objetivo de este estudio experimental fue comparar la aceptabilidad del sabor entre diferentes preparaciones con bajo contenido de sodio en pacientes diabéticos e hipertensos. Se realizó entre abril y mayo del 2015 en el Centro de Atención Integral de Diabetes e Hipertensión (CEDHI) en Lima, Perú. Las personas evaluadas fueron 67 pacientes ambulatorios del CEDHI, mayores de 18 años de ambos géneros, diagnosticados de hipertensión arterial o diabetes tipo 2. En total fueron aplicadas 134 pruebas sensoriales y 402 muestras preparadas. Las preparaciones que fueron sometidas a evaluación fueron arroz, caldo, pollo y verduras cocidas, adicionándoles sal común, cloruro de potasio [25%] con sal común [75%] y glutamato monosódico. Para medir los resultados se utilizaron dos pruebas hedónicas, de preferencia por ordenamiento y prueba de aceptabilidad (puntuación del 1 al 5). En los resultados no se encontraron diferencias significativas a nivel global en cuanto a la aceptabilidad y preferencia de las preparaciones con bajo contenido de sodio. Por lo cual, el reemplazo de la sal común por cualquiera de los sustitutos es viable para pacientes con prescripción de dieta hiposódica (1500 mg Na/día).

    • Acuerdo de asociación transpacífico: cuando la cura es peor que la enfermedad

      Solari, Lely; [email protected] (Instituto Nacional de Salud (INS), 2015-09)
      Peru is negotiating the Transpacific Partnership Agreement, a commercial treaty that could have deleterious implications for the health systems of the included partners. Transparency and Intellectual Property chapters are the most controversial elements. The first mostly because it opens the possibility for groups of interest to refuse decisions being taken by the sanitary authorities concerning the incorporation of health technologies to the public health systems. The second because it poses restrictions to the entrance of generic medical products, widening the period of data exclusivity and implementing mechanisms of opposition to their registry. Other chapters include strategies to block the states from regulating the consumption of alcohol, tobacco and processed foods. We ought to create surveillance systems to evaluate the impact of the agreement if it is signed, and generate mechanisms that prevent the little resources we already have devoted for health to be deviated to top technology that will not necessarily have a positive impact at a population level.

    • Acute Endovascular Reperfusion Therapy in Ischemic Stroke: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

      Osanai, Toshiya; Pasupuleti, Vinay; Deshpande, Abhishek; Thota, Priyaleela; Roman, Yuani; Hernández, Adrian V.; Uchino, Ken (The Public Library of Science (PLOS), 2015-05-06)
      Background Randomized controlled trials (RCTs) of endovascular therapy for acute ischemic stroke have had inconsistent results. We evaluated the efficacy and safety of endovascular therapy in published RCTs. Methods We performed a systematic review of RCTs of endovascular therapy with thrombolytic or mechanical reperfusion compared with interventions without endovascular therapy. Primary outcome was the frequency of good functional outcome (modified Rankin scale (mRS) of 0-2 at 90 days) and secondary outcomes were mortality at 90 days and symptomatic intracranial hemorrhage (sICH). Random-effects meta-analysis was performed and the Cochrane risk of bias assessment was used to evaluate quality of evidence. Results Ten studies involving 1,612 subjects were included. Endovascular therapy was not significantly associated with good functional outcome (Relative Risk [RR] =1.17; 95% CI, 0.97 to 1.42; p=0.10 and Absolute Risk Difference [ARD] =7%; 95%CI -0.1% to 14%; p=0.05); heterogeneity was moderate among studies (I2=30%). Mortality was unchanged with endovascular therapy (RR=0.92; 95 % CI, 0.75 to 1.13; p=0.45) and there was no difference in sICH (RR=1.20; 95 % CI, 0.79 to 1.82; p=0.39). The quality of evidence was low for all outcomes and the recommendation is weak for the use of endovascular therapy as per GRADE methodology. Conclusions Intra-arterial therapy did not show significant increase in good outcomes and no changes in either mortality or sICH in patients with acute ischemic stroke. We need further RCTs with better design and quality to evaluate the true efficacy of endovascular therapy.

    • Adenocarcinoma mucinoso de apéndice. Reporte de un caso

      Wolniczak Rodriguez, Isabella; Cáceres del Águila, Alonso; Santillana Callirgos, Juan Alberto; [email protected] (Sociedad de Gastroenterología del Perú (SGP), 2016-06)
      Mucinous adenocarcinoma of the appendix is a rare neoplasm with an incidence rate of 0.08% of all malignancies. The diagnosis is usually made by biopsy because its clinical presentation may mimic other diseases of structures located in the right lower quadrant. Currently, the treatment is still controversial, being surgery the best option. This report describes a patient with a history of appendectomy 27 years ago that is hospitalized for a painful mass in the lower abdomen associated with carcinoembryonic antigen of 138 ng/dl.

    • Adherencia a TARGA: enfoque multi-dimensional

      Vadillo, Sandra; López, Rosalie; Moreno, Jacqueline (Sociedad Chilena de Infectología, 2015-07-06)
      Leímos con interés el artículo de Varela y cols.1 sobre depresión y adherencia a terapia anti-retroviral en Chile, tema importante en el éxito de la terapia. Quisiéramos comentar lo siguiente: en primer lugar, muchos estudios coinciden en que las enfermedades psiquiátricas son las co-morbilidades que afectan en mayor medida a la adherencia terapia anti-retroviral de gran actividad (TARGA) directa o indirectamente2. En forma directa porque es la enfermedad psiquiátrica más diagnosticada en pacientes con infección por VIH e indirectamente porque es producto de otros factores de riesgo como uso de alcohol y drogas, efectos secundarios de fármacos, falta de soporte social y familiar, actitudes y creencias del paciente acerca del tratamiento2. Asimismo, se ha visto que la depresión afecta la adherencia al tratamiento de enfermedades crónicas3, por lo que la hipótesis de la asociación de depresión en adherencia a TARGA es a nuestro parecer válida.
