Nurses' perceptions and problems in the usability of a medication safety app.

Introduction: The majority of medication apps support medication adherence. Equally, if not more important, is medication safety. Few apps report on medication safety, and fewer studies have been conducted with these apps.

Intervening to promote early initiation of breastfeeding in the LDR.

Purpose: To evaluate the effectiveness of an interventional protocol for the early initiation of breastfeeding that would remove barriers in the labor, delivery, recovery (LDR) unit.

Study Design And Methods: Descriptive design using 100 postpartum mothers who were interviewed before discharge at a large university hospital in the south-central United States. Descriptive statistics were used for analysis.

Sentinel lymph node biopsy for breast cancer: improvement in results over time.

Many modifications in the technique of sentinel lymph node (SLN) biopsy for breast cancer have taken place since it was first introduced. This analysis was undertaken to determine, in a large multi-institutional study, whether SLN biopsy results have improved over time. Patients with clinical stage T1-2, N0 breast cancer were enrolled in this prospective study between August 1997 and February 2002.

Palpable breast carcinomas: a hypothesis for clinically relevant lymphatic drainage in sentinel lymph node biopsy.

Previous studies have shown that independent of tumor size, palpable breast tumors have a higher incidence of lymph node metastasis compared with nonpalpable tumors. This study further examines this phenomenon using a large sentinel lymph node (SLN) database. Data from a prospective, institutional review board (IRB)-approved, multi-institutional study from the University of Louisville Breast Cancer Sentinel Lymph Node Study Group was used.

The effect of lymphatic tumor burden on sentinel lymph node biopsy results.

Increasing tumor burden in the axilla, as determined by the number of positive lymph nodes, adversely affects sentinel lymph node (SLN) identification and false-negative rates. The University of Louisville Breast Cancer Sentinel Lymph Node Study is a prospective, multi-institutional study. All enrolled patients underwent SLN biopsy, followed by complete level I/II axillary dissection.

The effect of prior breast biopsy method and concurrent definitive breast procedure on success and accuracy of sentinel lymph node biopsy.

Background: It has been suggested that sentinel lymph node (SLN) biopsy for breast cancer may be less accurate after excisional biopsy of the primary tumor compared with core needle biopsy. Furthermore, some have suggested an improved ability to identify the SLN when total mastectomy is performed compared with lumpectomy. This analysis was performed to determine the impact of the type of breast biopsy (needle vs.
