Outcomes and Resource Utilization Associated with Use of Routine Pre-Discharge White Blood Cell Count for Clinical Decision-Making in Children with Complicated Appendicitis: A Multicenter Hospital-Level Analysis.

BACKGROUND: The objective was to explore the hospital-level relationship between routine pre-discharge WBC utilization (RPD-WBC) and outcomes in children with complicated appendicitis. METHODS: Multicenter analysis of NSQIP-Pediatric data from 14 consortium hospitals augmented with RPD-WBC data. WBC were considered routine if obtained within one day of discharge in children who did not develop an organ space infection (OSI) or fever during the index admission. Hospital-level observed-to-expected ratios (O/E) for 30-day outcomes (antibiotic days, imaging utilization, healthcare days, and OSI) were calculated after adjusting for appendicitis severity and patient characteristics. Spearman correlation was used to explore the relationship between hospital-level RPD-WBC utilization and O/E's for each outcome. RESULTS: 1528 children were included. Significant variation was found across hospitals in RPD-WBC use (range: 0.7-100%; p < 0.01) and all outcomes (mean antibiotic days: 9.9 [O/E range: 0.56-1.44, p < 0.01]; imaging: 21.9% [O/E range: 0.40-2.75, p < 0.01]; mean healthcare visit days: 5.7 [O/E 0.74-1.27, p < 0.01]); OSI: 14.1% [O/E range: 0.43-3.64, p < 0.01]). No correlation was found between RPD-WBC use and antibiotic days (r = +0.14, p = 0.64), imaging (r = -0.07, p = 0.82), healthcare days (r = +0.35, p = 0.23) or OSI (r = -0.13, p = 0.65). CONCLUSIONS: Increased RPD-WBC utilization in pediatric complicated appendicitis did not correlate with improved outcomes or resource utilization at the hospital level. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Clinical Research.

[Complicated Malaria in Chocó: clinical findings and data comparison with the monitoring system]. / Malaria complicada en el Chocó: hallazgos clínicos y comparación de datos con el sistema de vigilancia.

OBJECTIVES: To describe the epidemiological and clinical cases of complicated malaria and to establish the concordance of this information in the surveillance system. METHODOLOGY: Information was obtained from medical records of cases reported in 2011 in the surveillance system and the Hospital San Francisco. We selected a clinical sample of 62 stories of 113 cases and health professionals reviewed the information. The presence of positive thick drop with one or more criteria of complication was taken into account to define if the clinical history corresponded to complicated malaria, according to guide national clinic and tab of the surveillance system. Statistical significance was determined with Chi square and the Kappa statistic. RESULTS: The 37.0% of cases presented a complication, 63.0% had two or more complications. Major complications were thrombocytopenia and severe anemia, followed by hepatic complication, hiperparasitemia, renal insufficiency and cerebral malaria. In 3 of the 54 cases intravenous artesunate was used, quinine was used in 59.2%. Comparison of demographic variables and parasitic species between history and the surveillance system show no significant difference but type of complication was almost nil. The major reported complications do not appear on the notification tab. DISCUSSION: Further studies need to be continued in order to contribute to the clinical characterization of malaria in the Department and Management interventions. Adjustments to format are recommended to strengthen analysis and decision-making.

OBJETIVOS: Describir las características epidemiológicas y clínicas de casos de malaria complicada y establecer la concordancia de esta información con el sistema de vigilancia. METODOLOGÍA: La información se obtuvo de historias clínicas de casos informados en 2011 en el sistema de vigilancia atendidos en el Hospital San Francisco. Se seleccionó una muestra de 62 historias clínicas de 113 casos. Para definir que la historia clínica correspondía a malaria complicada se tuvo en cuenta la presencia de gota gruesa positiva con uno o más criterios de complicación, según la guía clínica nacional y la ficha del sistema de vigilancia. La significancia estadística se determinó con el Chi2 y el estadístico Kappa. RESULTADOS: El 37% de los casos presentó una complicación, el 63% presentaron dos o más complicaciones. Las principales complicaciones fueron trombocitopenia y anemia severa, seguido de complicación hepática, hiperparasitemia, insuficiencia renal y malaria cerebral. En tres de los 54 casos, se usó el Artesunato intravenoso. Se utilizó Quinina en el 59,2% de los casos.La comparación de variables demográficas y especie parasitaria entre las fuentes utilizadas no muestra diferencias significativas, pero el acuerdo general de tipo de complicación fue casi nulo. Las principales complicaciones reportadas no aparecen en la ficha de notificación. DISCUSIÓN: Es necesario continuar otros estudios con el fin de contribuir en la caracterización clínica de la malaria en el Departamento y las intervenciones de manejo. Se recomiendan ajustes a la ficha para fortalecer el análisis y la toma de decisiones.

The role of heparan sulfate on adhesion of 47 and 51 kDa outer membrane proteins of Helicobacter pylori to gastric cancer cells.

Helicobacter pylori is a common gastrointestinal pathogenic bacterium in humans and the usual preference for the stomach's outer membrane proteins (OMPs) are antigens involved in the adhesion process. Through SDS-PAGE and blotting analyses, using horseradish peroxidase-labeled heparan sulfate (HRP-HS) as a probe, we identified H. pylori OMPs with affinity for heparan sulfate (OMP-HS). Biotin-streptavidin bacterial-adhesion assay was used to evaluate participation of OMP-HS in the adhesion of H. pylori to semi-confluent HeLa S3 and Kato III cell monolayers. The results provide evidence that induction of antibodies against 2 OMP-HSs (HSBP-47 and HSBP-51) could reduce binding of H. pylori to both cell lines and induce detachment of cell-bound bacteria from infected cultured cells.
