Clinical features and preventability of delayed diagnosis of pediatric appendicitis.
In this case-control study, researchers sought to determine clinical features associated with delayed diagnosis of pediatric appendicitis, to assess the frequency of preventable delay, and to compare delay outcomes. They found that delayed appendicitis was associated with initially milder symptoms but worse outcomes. Their findings suggest that a majority of delayed diagnoses were at least possibly preventable and that many of the studied patients did not undergo indicated imaging, suggesting an opportunity to prevent delayed diagnosis of appendicitis in some children.

The "sweet spot" revisited: optimal recall rates for cancer detection with 2D and 3D digital screening mammography in the Metro Chicago Breast Cancer Registry.
The authors examined the trade-offs for higher recall rates in terms of biopsy recommendations and cancer detection in mammography in a single large health care organization. 2D analog, 2D digital, and 3D digital mammography screenings among women 40-79 years old with cancer follow-up were examined. They found that the results of their investigation were in contrast to those of a recent study suggesting appropriateness of higher recall rates. They concluded that optimal cancer detection appeared to be in the recall rate range of 7-9% for both 2D digital mammography and 3D tomosynthesis.

Cost-effectiveness of dual maternal HIV and syphilis testing strategies in high and low HIV prevalence countries: a modelling study.
Dual HIV and syphilis testing might help to prevent mother-to-child transmission (MTCT) of HIV and syphilis through increased case detection and treatment. In this study, the investigators aimed to model and assess the cost-effectiveness of dual testing during antenatal care in four countries with varying HIV and syphilis prevalence. The authors concluded that incorporating dual rapid diagnostic tests in antenatal care could be cost-saving across countries with varying HIV prevalence.

Association between persistence with mammography screening and stage at diagnosis among elderly women diagnosed with breast cancer.
The objective of this study is to determine the association between persistence with mammography screening and stage at breast cancer (BC) diagnosis among elderly women. It found that, as compared to women who were not persistent with mammography screening, women who were persistent with mammography screening were significantly more likely to be diagnosed at earlier stages of BC.

Use of the modified early warning score and serum lactate to prevent cardiopulmonary arrest in hematology-oncology patients: a quality improvement study.
The authors aimed to improve the early identification of clinically deteriorating hematology-oncology patients in order to prevent the development of critical illness and to facilitate timely intensive care unit (ICU) transfers. They used a protocol employing the Modified Early Warning Score and found that implementation of this protocol reduced codes and preventable codes without an associated increase in ICU transfers.
