Candidate metrics for evaluating the impact of prescriber education on the safe use of extended-release/long-acting (ER/LA) opioid analgesics.

Objective: The objective of this study was to develop metrics to assess opioid prescribing behavior as part of the evaluation of the Extended-Release/Long-Acting (ER/LA) Opioid Analgesic Risk Evaluation and Mitigation Strategies (REMS).

Design: Candidate metrics were selected using published guidelines, examined using sensitivity analyses, and applied to cross-sectional rolling cohorts of Medicare patients prescribed with extended-release oxycodone (ERO) between July 2, 2006 and July 1, 2011. Potential metrics included prescribing opioid-tolerant-only ER/LA opioid analgesics to non-opioid-tolerant patients, prescribing early fills to patients, and ordering drug screens.

Chart-confirmed guillain-barre syndrome after 2009 H1N1 influenza vaccination among the Medicare population, 2009-2010.

Given the increased risk of Guillain-Barré Syndrome (GBS) found with the 1976 swine influenza vaccine, both active surveillance and end-of-season analyses on chart-confirmed cases were performed across multiple US vaccine safety monitoring systems, including the Medicare system, to evaluate the association of GBS after 2009 monovalent H1N1 influenza vaccination. Medically reviewed cases consisted of H1N1-vaccinated Medicare beneficiaries who were hospitalized for GBS. These cases were then classified by using Brighton Collaboration diagnostic criteria.

Housing assistance and case management: improving access to substance use disorder treatment for homeless veterans.

The problem of waiting list attrition in addiction treatment programs is widespread, and homeless and marginally housed individuals are particularly susceptible. This naturalistic, retrospective study describes an intervention (Transitional Supportive Housing and Case Management) that effectively promoted treatment admission for this high-risk group above and beyond that which could be explained by certain pretreatment factors. The clinical records of 211 military veterans referred to intensive outpatient addiction treatment were reviewed for factors related to treatment program admission, including 3 interventions designed to prevent waiting list attrition.

Outpatient transfusions and occurrence of serious noninfectious transfusion-related complications among US elderly, 2007-2008: utility of large administrative databases in blood safety research.

Background: Transfusion-related acute lung injury (TRALI) and hemolytic transfusion reactions account for significant transfusion-related morbidity and mortality in the United States. Our study evaluated types and quantities of transfused components as well as occurrence of TRALI, ABO, and Rh incompatibilities among the US elderly in the institutional outpatient setting during 2007 to 2008.

Study Design And Methods: This retrospective claims-based study utilized the Centers for Medicare & Medicaid Services' large administrative databases.

Babesiosis among elderly Medicare beneficiaries, United States, 2006-2008.

We used administrative databases to assess babesiosis among elderly persons in the United States by year, sex, age, race, state of residence, and diagnosis months during 2006-2008. The highest babesiosis rates were in Connecticut, Rhode Island, New York, and Massachusetts, and findings suggested babesiosis expansion to other states.

Reporting on reliability and validity of outcome measures in medical rehabilitation research.

Purpose: To evaluate the degree to which published medical rehabilitation research offers evidence of reliability, validity and other clinimetric qualities of the data reported.

Method: Descriptive study of published intervention research papers published in six US medical rehabilitation journals in 1997 and 1998. Selected characteristics of the papers and the outcome measures used were abstracted by one or two raters.

Quality of intervention research reporting in medical rehabilitation journals.

Objective: To evaluate the degree to which rehabilitation researchers report information on the interventions they evaluate.

Design: Intervention research articles published in six United States medical rehabilitation journals in 1997-1998 were rated on the presence or absence of information on the overall design, intervention used, and outcome measures. Rating was performed independently by two authors who used discussion to resolve disagreements.

Single-step multiplex PCR assay for characterization of New World Leishmania complexes.

We have developed a PCR assay for one-step differentiation of the three complexes of New World Leishmania (Leishmania braziliensis, Leishmania mexicana, and Leishmania donovani). This multiplex assay is targeted to the spliced leader RNA (mini-exon) gene repeats of these organisms and can detect all three complexes simultaneously, generating differently sized products for each complex. The assay is specific to the Leishmania genus and does not recognize related kinetoplastid protozoa, such as Trypanosoma cruzi, Trypanosoma brucei, and Crithidia fasciculata.

Asymmetrically primed selective amplification/temperature shift fluorescence polymerase chain reaction to detect the hemoglobin Constant Spring mutation.

Hemoglobin (Hb) Constant Spring is an alpha-thalassemic hemoglobinopathy that is a major cause of severe alpha-thalassemia in Southeast Asians. The difficulty of diagnosing Hb Constant Spring using standard electrophoretic methods has led to interest in DNA-dependent diagnostic methods. The methods developed have had to contend with the high degree of homology of the alpha 2-globin gene (the site of the Hb Constant Spring mutation) and the alpha 1-globin gene.

Detection of the hemoglobin E mutation using the color complementation assay: application to complex genotyping.

The color complementation assay (CCA) is a method of allele-specific DNA amplification by which competitive priming and extension of fluorescently labeled oligonucleotide primers determine the color of DNA amplification product. This diagnostic method precludes the need for radioisotopes, electrophoresis, and multiple high-stringency reaction conditions. The multiplicity of mutant globin genes present in Southeast Asians complicates clinical diagnosis and underscores the importance of DNA-based diagnostic methods.

Selective enzymatic amplification of alpha 2-globin DNA for detection of the hemoglobin Constant Spring mutation.

Hemoglobin Constant Spring is an elongation mutation of the alpha 2-globin locus that results in a thalassemic phenotype. It has a high prevalence in Asian populations. When inherited with other alpha-thalassemia determinants, the Constant Spring gene has the potential to cause severe forms of alpha-thalassemia.

[Excision and removal of multiple polyps of the colon (author's transl)].

Nowadays polyps in the gastrointestinal tract are usually removed under endoscopy, the method being highly effective and of low risk. Endoscopic removal, if necessary in several sessions, can be easily done even if there are multiple polyps of the colon. Altogether 69 polyps were removed from a 33-year-old woman, their microscopic appearance showing various degrees of proliferation.
