Missed Opportunities for Preventing or Diagnosing Acute Rheumatic Fever: A Retrospective Cohort Study of 20 Young Australians Diagnosed With Rheumatic Heart Disease on Screening Echocardiography.

Background And Aim: A cross-sectional echocardiographic screening study in a remote Aboriginal community in Australia identified hyperendemic levels of rheumatic heart disease (RHD). 20/613 screened were newly diagnosed with RHD, and 18/20 had no known history of acute rheumatic fever (ARF). Our aim was to explore the medical histories of those newly diagnosed with RHD for potential (1) missed opportunities for primary prevention of ARF through management of Group A Streptococcal (Strep A) infection, and (2) missed opportunities for diagnosis of ARF.

A Bioimpedance Spectroscopy-Based Method for Diagnosis of Lower-Limb Lymphedema.

This study aimed at testing whether arm-to-leg ratios of extracellular water (ECW) and ECW normalized to intracellular water (ICW), measured by bioimpedance spectroscopy (BIS), can accurately detect bilateral, lower-limb lymphedema, and whether accounting for sex, age, and body mass index (BMI) improves the diagnostic performance of cut-offs. We conducted a dual-approach, case-control study consisting of cases of bilateral, lower-limb lymphedema and healthy controls who self-reported absence of lymphedema. The diagnostic performance using normative data-derived cut-offs (i.

Normative Interlimb Impedance Ratios: Implications for Early Diagnosis of Uni- and Bilateral, Upper and Lower Limb Lymphedema.

Bioimpedance spectroscopy detects unilateral lymphedema if the ratio of extracellular fluid (ECF) between arms or between legs is outside three standard deviations (SDs) of the normative mean. Detection of bilateral lymphedema, common after bilateral breast or gynecological cancer, is complicated by the unavailability of an unaffected contralateral limb. The objectives of this work were to (1) present normative values for interarm, interleg, and arm-to-leg impedance ratios of ECF and ECF normalized to intracellular fluid (ECF/ICF); (2) evaluate the influence of sex, age, and body mass index on ratios; and (3) describe the normal change in ratios within healthy individuals over time.
