Implementación de Enterprise Performance Management para la planificación presupuestal de Business & Decision LATAM
Este proyecto consiste en la implementación de Enterprise Performance Management para poder optimizar de control presupuestal de la consultora Business & Decision LATAM (B&D LATAM), así mismo, centralizar el control operativo de la asignación de recursos (Consultores) y margen de contribución que tiene cada proyecto a implementarse. Para lograr la implementación nos apoyaremos de la metodología de proyectos BIP (Business & Decision Initiative for Performance) personalizada, definida por la división de Calidad de Software de B&D LATAM. El principal resultado obtenido fue la mejora de la capacidad de gestionar y controlar el proceso presupuestal y proyecciones que brinda la herramienta EPM. Los resultados de este proyecto demuestran la gran utilidad que este tipo de herramientas representa al permitir discriminar la producción efectiva de cada consultor y de cuánto tiempo tiene sin afectación a un proyecto durante su estadía en la compañía. Este proyecto permite concluir que el control presupuestal eficiente en una organización consultora de sistemas posibilita el ahorro de costos al administrar adecuadamente las contrataciones de nuevo personal, y de la gestión de cumplimiento de objetivos comerciales. Este proyecto también demuestra la gran flexibilidad y capacidad del motor de cálculo de la herramienta Hyperion Planning, permitiendo tener como resultado un estado de ganancias y pérdidas que permita la salud financiera de la compañía

La investigación fue ejecutada en la Institución Educativa N° 16388 del
Centro Poblado Francisco Bolognesi - San Ignacio. Su diseño fue pre
experimental de tipo aplicativo – explicativo, en el que se utilizó un pre test y un
post test con un grupo experimental. Se trabajó con una población y muestra de
21 estudiantes del 4° grado de educación primaria, y para el recojo de datos fue
aplicada una encuesta que sirvió de pre test y post test, para evaluarlo antes y
después de aplicado el programa. Se consideró a la Institución Educativa San
Luis Gonzaga Fe y Alegría Nº 22 como centro piloto referente para la validación
del constructo del Instrumento.
Del análisis de las tablas y gráficos estadísticos de la investigación realizada
arrojó los siguientes resultados: se observa que los estudiantes en su mayoría se
sitúan en logro previsto con el 61.91% en el nivel literal, 42.86% en el nivel
inferencial y 47.63 en el nivel crítico y también ya se observa porcentajes en el
logro destacado. Esto indica que la utilización del enfoque interactivo repercutió
favorablemente en mejorar la comprensión de los 21 estudiantes
Hepatotoxicity induced by isoniazid in patients with latent tuberculosis infection: a meta-analysis
Adverse drug reaction; Latent tuberculosis; Liver injuryReacción adversa a medicamentos; Tuberculosis latente; Lesión hepáticaReacció adversa a medicaments; Tuberculosi latent; Lesió hepàticaAim: The aim of the present study was to conduct a meta-analysis of the frequency of isoniazid-induced liver injury (INH-ILI) in patients receiving isoniazid (INH) preventative therapy (IPT).
Background: The frequency of hepatotoxicity (drug-induced liver injury: DILI) of antituberculosis drugs has been studied, especially when INH, rifampin, and pyrazinamide are co-administered. However, little is known about the frequency of DILI in patients with latent tuberculosis infection (LTBI), where IPT is indicated.
Methods: We searched PubMed, Google Scholar, and the Cochrane Database of Systematic Reviews for studies reporting the frequency of INH-ILI in patients with IPT using one or more diagnostic indicators included in the criteria of the DILI Expert Working Group.
Results:
Thirty-five studies comprising a total of 22,193 participants were included. The overall average frequency of INH-ILI was 2.6% (95% CI, 1.7-3.7%). The mortality associated with INH-DILI was 0.02% (4/22193). Subgroup analysis revealed no significant differences in the frequency of INH-ILI in patients older or younger than 50 years, children, patients with HIV, candidates for liver, kidney, or lung transplant, or according to the type of study design.
Conclusion: The frequency of INH-ILI in patients receiving IPT is low. Studies on INH-ILI are needed where the current DILI criteria are used
Evaluation of the Timed Up and Go test for screening vulnerability and frailty in older cancer patients
Introduction. The need for comprehensive geriatric assessment (CGA) in older adults with cancer is increasing, which makes it necessary to have a screening instrument to identify those who would benefit from this evaluation. This study aimed to investigate diagnostic performance of the Timed Up and Go test (TUG) for identifying vulnerable or frail older adults with cancer who might benefit from CGA.
Material and methods. This observational and retrospective study took place at the geriatric center of Almenara Hospital in Lima, Peru. We extracted CGA reports from electronic medical records of outpatients and inpatients aged 60 years and older with cancer, who were evaluated between November 2022 and July 2023. Patients were classified based on SIOG-2 (International Society of Geriatric Oncology) criteria as fit, vulnerable, or frail, based on scales including Activities of Daily Living (ADL), Instrumental ADL, Mini-Nutritional Assessment (MNA), Mini-Mental State Exam (MMSE), Geriatric Depression Scale, and Cumulative Illness Rating Scale-Geriatrics (CIRS-G). For the study, two groups were formed: fit patients and non-fit patients (vulnerable plus frail). We estimated sensitivity, specificity, and positive predictive values of the TUG test. The accuracy of the TUG test was analyzed using the area under the receiver operating characteristic curve (AUC).
Results. Among the 283 included patients, 154 were men (54.4%) and 129 women (45.6%), and the mean age was 76.8 ± 15.8 years. The most common neoplasms were colorectal (19.4%), stomach (15.2%), prostate (9.9%), and bile duct cancers (8.1%). The percentage of fit and non-fit patients was 21.9% and 78.1%, respectively. When the TUG test was equal to or greater than 15.5 seconds, sensitivity, specificity, positive predictive value, and AUC were 68.5% (95% CI 61.9–74.5), 88.5% (77.8–95.3), 95.6% (91.1–98.2), and 84.8% (0.80–0.90), respectively.
Conclusions. A TUG test result equal to or greater than 15.5 seconds demonstrated good screening properties for identifying older cancer patients who were vulnerable or frail and could benefit from CGA
Comprehensive geriatric assessment and clinical outcomes of frail older adults with diffuse large B-cell lymphoma: a metanalysis
Introduction. Comprehensive geriatric assessment (CGA) is used to personalize cancer treatments in frail older adults. However, its utility to guide treatments in frail older patients with diffuse large B-cell lymphoma (DLBCL) is not well known. We performed a meta-analysis of evidence published in this area.
Material and methods. We searched PubMed and Google Scholar for studies published between January 2000 and January 2023 that included patients aged ≥ 65 years with a diagnosis of DLBCL who underwent CGA before treatment (CGA-modulated studies) and who did not (non-CGA-modulated studies). We evaluated clinical outcomes in frail/unfit patients in terms of complete response (CR), incidence of grade ≥ 3 toxicity, and 2-year overall survival (OS) in both types of studies.
Results. Fifteen studies [8 CGA-modulated (n = 733, median age 76, 54% male, 52% frail/unfit) and 7 non-CGA-modulated (n = 2447, median age 76, 52% male, 32% frail/unfit)] were included. In the CGA-modulated studies, the CR proportion of frail/unfit patients was 34% (95% CI 23–46%) vs. 28% (95% CI 19–38%) in the non-CGA-modulated studies (p = 0.436). Grade 3–4 hematological toxicity in frail/unfit patients was 26% (95% CI 5–55%) vs. 36% (95% CI 13–63%) (p = 0.583), respectively. Two-year OS of frail/unfit patients was 52% (95% CI 38–66%) vs. 27% (95% CI 19–36%) (p = 0.003), respectively.
Conclusions. Although the proportion of frail/unfit patients was lower in non-CGA-modulated studies, CGA-modulated studies reported higher OS. CGA could be useful to guide the treatment plan in older patients with DLBCL. Randomized clinical trials with standardized CGA instruments are necessary to confirm these findings
