Importance and Difficulties of Pursuing rTMS Research in Acute Stroke.

Although much research has been done on repetitive transcranial magnetic stimulation (rTMS) in chronic stroke, only sparse research has been done in acute stroke despite the particularly rich potential for neuroplasticity in this stage. We attempted a preliminary clinical trial in one active, high-quality inpatient rehabilitation facility (IRF) in the -United States. But after enrolling only 4 patients in the grant period, the study was stopped because of low enrollment. The purpose of this paper is to offer a perspective describing the important physiologic rationale for including rTMS in the early phase of stroke, the reasons for our poor patient enrollment in our attempted study, and recommendations to help future studies succeed. We conclude that, if scientists and clinicians hope to enhance stroke outcomes, more attention must be directed to leveraging conventional rehabilitation with neuromodulation in the acute phase of stroke when the capacity for neuroplasticity is optimal. Difficulties with patient enrollment must be addressed by reassessing traditional inclusion and exclusion criteria. Factors that shorten patients' length of stay in the IRF must also be reassessed at all policy-making levels to make ethical decisions that promote higher functional outcomes while retaining cost consciousness.

Utility of Oncotype DX Risk Assessment in Patients With Invasive Lobular Carcinoma.

INTRODUCTION/BACKGROUND: Oncotype DX (Genomic Health, Redwood City, CA) uses reverse transcriptase polymerase chain reaction analysis to measure tumor gene expression for determining recurrence risk (RR) and guiding chemotherapy decisions for breast cancer patients. Invasive lobular carcinoma (ILC) is a histologic subtype that has not been the focus of prior studies validating Oncotype DX. The study purpose was to develop a model using histologic tumor characteristics to predict uniformly low Oncotype DX Recurrence Scores (RS) in ILC. PATIENTS AND METHODS: ILC cases in our pathology database with Oncotype DX testing were identified. Histologic tumor characteristics, immunohistochemical (IHC) of estrogen receptor (ER)/progesterone receptor (PgR) percent, HER2, E-cadherin expression, and Ki-67 levels were obtained for cases. Discriminant analysis was used to test the hypothesis that tumors classified as lower/higher risk based on Oncotype DX RS would differ significantly on a linear combination of variables. RESULTS: From 2006 - 2014, 158 cases of ILC having Oncotype DX testing were identified; 90 low risk (RS < 18), 66 intermediate risk (RS 18 - 30) and 2 high risk (RS > 30). Discriminant analysis showed that PgR% followed by Ki-67 provided the greatest contribution to discern low versus elevated RS. A subset of 57 cases (∼36%) with predicted probabilities > 86% for either low or high RS yielded 96.5% correct classification, 92.3% sensitivity, and 97.7% specificity. CONCLUSION: Our analytical model may be useful in predicting lower RR in patients with ILC. If validated, this provides a faster and less expensive alternative to Oncotype DX testing in certain patients with ILC.

Feasibility of early functional rehabilitation in acute stroke survivors using the Balance-Bed-a technology that emulates microgravity.

Evidence-based guidelines recommend early functional rehabilitation of stroke patients when risk of patient harm can be managed. Current tools do not allow balance training under load conditions sufficiently low for acute stroke patients. This single-arm pilot study tested feasibility and safety for acute stroke survivors to use "Balance-Bed", a technology for balance exercises in supine initially developed to emulate microgravity effects on balance. Nine acute stroke patients (50-79 years) participated in 3-10 sessions over 16-46 days as part of their rehabilitation in a hospital inpatient setting. Standard inpatient measures of outcome were monitored where lack of progress from admission to discharge might indicate possible harm. Total FIM scores at admission (median 40, range 22-53) changed to (74, 50-96), Motor FIM scores from (23, 13-32) to (50, 32-68) and Berg Balance scores from (3, 0-6) to (19, 7-43) at discharge. Changes reached Minimal Clinical Important Difference for a sufficient proportion (>0.6) of the patients to indicate no harm to the patients. In addition, therapists reported the technology was safe, provided a positive experience for the patient and fit within the rehabilitation program. They reported the device should be easier to set up and exit. We conclude acute stroke patients tolerated Balance-Bed exercises such as standing on one or two legs, squats, stepping in place as well as balance perturbations provided by the therapist. We believe this is the first time it has been demonstrated that acute stroke patients can safely perform whole body balance training including balance perturbations as part of their rehabilitation program. Future studies should include a control group and compare outcomes from best practices to interventions using the Balance-Bed. In addition, the technology is relevant for countermeasure development for spaceflight and as a test-bed of balance function under microgravity-like conditions.

Long-term effects of safe patient handling program on staff injuries.

PURPOSE: This study evaluated the effectiveness of a safe patient handling program (STEPS) at an inpatient rehabilitation unit in reducing injury due to patient transfers. Our objectives were to compare number of staff injuries during the 1.5-year period post training to pre training (baseline) and to determine whether reduction in injuries was sustained long term during a 2.5-year post training period. METHODS: All nursing and therapy staff as well as new hires received STEPS training. Periodic retraining was not provided. FINDINGS: The number of injuries was significantly reduced at post training compared to baseline (p = 0.01). However, the reductions in injuries were not sustained long term. CONCLUSION: We estimated a cost benefit of $3.71 for every dollar invested in retraining based on injury reduction realized during the post training period. CLINICAL RELEVANCE: Retraining is likely to have a positive cost benefit when it results in maintaining reduction in staff injuries.

How well does serum bicarbonate concentration predict the venous pH in children being evaluated for diabetic ketoacidosis?

OBJECTIVE: The objective of the study was to determine whether serum bicarbonate (HCO3) concentration can accurately predict venous pH in the evaluation of diabetic ketoacidosis (DKA). METHODS: A retrospective review of patients who presented to a children's hospital emergency department and received an International Classification of Diseases, Ninth Revision code related to DKA or diabetes mellitus was performed. To be eligible for inclusion and data abstraction, patients had blood sampled simultaneously for venous blood gas and metabolic panel. A linear regression model was created using pH (dependent variable) and HCO3 (predictor). The diagnostic performance and accuracy of HCO3 to discriminate abnormal pH were evaluated using receiver operating characteristic curve analysis. RESULTS: Three hundred patients met the inclusion criteria. The linear relationship between pH and HCO3 using the Pearson correlation coefficient was found to be R = 0.89 (confidence interval [CI], 0.83-0.95; R = 0.79). Receiver operating characteristic curve analysis that maximized sensitivity and specificity demonstrated that a HCO3 18.5 or less predicts pH less than 7.3 (area under the curve = 0.97; CI, 0.94-0.99; sensitivity, 93%; specificity, 91%), and a HCO3 10.5 or less predicts pH less than 7.1 (area under the curve = 0.97; CI, 0.95-0.99; sensitivity, 97%; specificity, 88%). CONCLUSIONS: Serum bicarbonate accurately predicts abnormal venous pH in children with DKA. Venous pH determination may not be necessary for all patients being evaluated for DKA.

NICU practices and outcomes associated with 9 years of quality improvement collaboratives.

OBJECTIVE: Quality improvement collaboratives (QICs) can improve short-term outcomes, but few have examined their long-term results. This study evaluated the changes in treatment practices and outcomes associated with participation in multiple sequential QICs. DESIGN AND METHODS: This retrospective, 9-year, pre-post study of very low birth weight infants, we assessed treatment and outcomes from the 8 NICUs of the Reduce Lung Injury (ReLI) group of a QIC sponsored by the Vermont Oxford Network (VON). We analyzed data from 1998 (pre-ReLI), 2001 (last ReLI year), and 2006 (5 years after ReLI) by using univariate and multiple regression. RESULTS: A total of 4065 very low birth weight infants were treated in ReLI NICUs in 1998, 2001, and 2006. From 1998 to 2006, the ReLI group decreased delivery room intubation (70% vs 52%; adjusted odds ratio [aOR]: 0.2 [95% confidence interval (CI): 0.2-0.3]; P < .001), conventional ventilation (75% vs 62%; aOR: 0.3 [95% CI: 0.2-0.4]; P < .001), and postnatal steroids for BPD (35% vs 10%; aOR: 0.09 [95% CI: 0.07-0.1]; P < .001). They increased the use of nasal continuous positive airway pressure (57% vs 78%; aOR: 3.3 [95% CI: 2.7-3.9]; P < .001). BPD-free survival remained unchanged (68% vs 66%; aOR: 0.9 [95% CI: 0.7-1.1]; P = .16), the BPD rate increased (25% vs 29%; aOR: 1.3 [95% CI: 1.1-1.6]; P = .017), survival to discharge increased (90% vs 93%; aOR: 1.5 [95% CI: 1.1-2.2]; P < .001), and nosocomial infections decreased (18% vs 15%; aOR: 0.8 [95% CI: 0.6-0.99]; P = .045). CONCLUSIONS: Participation in VON-sponsored QICs was associated with sustained implementation of potentially better respiratory practices, increased survival, and reduced nosocomial infections. The BPD-free survival rate did not change, and the BPD rate increased. Implemented changes endured for at least 5 years after the QIC.

Impact of changes in infant death classification on the diagnosis of sudden infant death syndrome.

This study evaluates the hypothesis that a decline in sudden infant death syndrome in Minnesota is associated with increases in other categories of sudden unexpected infant death. Matched birth and death certificates, autopsy reports, and home visit questionnaires were reviewed for 722 sudden unexpected infant deaths that occurred from January 1, 1996 through December 31, 2002. Descriptive data and cause of death were recorded. Cause of death was compared for 2 periods: early (1996-1998) and late (2000-2002). The age of the infant at death, sex, race, and infant death rates were similar between the 2 periods ( P = .637). Sudden infant death syndrome declined by 50.1% (P < .001). Overlay deaths increased 235.5% (P < .01). Asphyxia related deaths increased 259.6% (P < .001). Injury-related deaths increased 840.0% (P < .001). A decline in sudden infant death syndrome in Minnesota was associated with increased deaths in categories that are asphyxial in nature and are potentially preventable.

Type I pleuropulmonary blastoma: a report from the International Pleuropulmonary Blastoma Registry.

PURPOSE: Type I pleuropulmonary blastoma (PPB) is a rare, cystic lung neoplasm in infants characterized by subtle malignant changes and a good prognosis. Recurrences after type I PPB are usually advanced type II or type III neoplasms with a poor prognosis. This article describes the first collection of type I PPB cases, analyzes outcome based on treatments of surgery or surgery plus chemotherapy, and presents type I PPB management recommendations. PATIENTS AND METHODS: Type I PPB cases from the International PPB Registry and literature were evaluated using standard statistical methods for outcomes based on age at diagnosis, sex, thoracic side, surgical extent, length of follow-up, constitutional/familial disease, pre-existing lung cysts, intrathoracic findings, and treatments (surgery or surgery and chemotherapy). RESULTS: Thirty-eight type I PPB cases were identified: Registry (n = 30) and literature (n = 8). Twenty children had surgery alone; eight (40%) experienced recurrence; and four died. Eighteen children had surgery and adjuvant chemotherapy; one experienced recurrence and died. All recurrences were type II or III PPB. Recurrence-free survival was higher in the surgery + chemotherapy group (P = .01); overall survival did not differ (P = .18). The improved recurrence-free survival was found only in males. Four of nine children with recurrence survived. CONCLUSION: Adjuvant chemotherapy appears to benefit type I PPB patients. Benefit limited to males requires broader substantiation. Salvage after types II and III recurrence is poor (four of nine; 44%). A rigorous surveillance schedule after type I PPB diagnosis might detect early recurrence and be an acceptable alternative to adjuvant chemotherapy.
