Tracking ‘Near Misses’ to Keep Newborns Safe From Falls

There is an increasing focus to keep newborns in the hospital safe from falls, as reports indicate that infant falls can occur in the immediate postpartum period. Previous reports have identified factors present at the time of newborn falls, yet there is little information on the prevalence of “near misses” or on risk factors present prior to the occurrence of falls. This article describes an innovative project to prevent newborn falls using information gathered about near misses. Most near misses occurred on the night shift, had the mother holding the baby and occurred an average of 52.6 hours after delivery. Collaboration among staff and patients is crucial to address risk factors present during near misses and to ultimately prevent newborn falls both in the hospital and at home.     

Nurses Share Real‐Life Research Experiences

Nursing for Women's Health convened a group of nurse researchers for a roundtable discussion about the relationship of research to the profession of nursing, how research drives evidence‐based practice and how nurses can get involved in research and in its application to the care of women and newborns.     

Diffusion tensor imaging and fiber tractography of C6 rat glioma

PURPOSE: To apply diffusion tensor images using 30 noncollinear directions for diffusion-weighted gradient schemes to characterize diffusion tensor imaging (DTI) features associated with C6 glioma-bearing rat brains, and ideally visualize fiber tractography datasets. MATERIALS AND METHODS: Fiber tractographies of normal male Fischer 344 rat brains were constructed from DTI datasets acquired with a 30 noncollinear diffusion gradient scheme. Cultured C6 cell were intracranially injected into the cortex of male Fischer 344 rats. The time course of the tumor growth was monitored with DTI and fiber tractography using diffusion-weighting gradients in 30 noncollinear directions. RESULTS: Fiber tractographies through the corpus callosum (CC) were easily visualized with the 30-direction gradient scheme, and the fiber trajectories of the motor cortex and striatum were well represented in normal rats. Fiber tractography indicated that the neuronal fibers of the CC were compressed or disappeared by growing C6 glioma, which affected surrounding brain tissue. CONCLUSION: We have demonstrated in this study that fiber tractography with the 30 noncollinear diffusion gradient scheme method can be used to help provide a better understanding regarding the influence of a tumor on the surrounding regions of normal brain tissue in vivo.     

Prevalence of prostatitis-like symptoms in a community based cohort of older men

PURPOSE: We describe a community based study to estimate the prevalence of prostatitis-like symptoms using questions similar to the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI). MATERIALS AND METHODS: Study subjects were a randomly selected sample of Olmsted County, Minnesota white men 40 to 79 years old in January 1990 who participated in a longitudinal study of lower urinary tract symptoms. Subjects were evaluated biennially using self-administered questionnaires. In 2000 questions similar to the NIH-CPSI were incorporated into the questionnaire and questionnaire responses were used to categorize men as having prostatitis-like symptoms. RESULTS: Of 1,541 men 182 (12%) had at least 1 urogenital pain symptom. Pubic (76 men, 4.9%) and testicular (73, 4.7%) pain were the most frequent pain symptoms. A total of 34 men with prostatitis-like symptoms (2.2%) had higher mean pain (6.7 versus 0.5), urinary symptom (3.5 versus 2.1) and quality of life impact (3.7 versus 1.9) scores compared to men who did not (all p <0.001). Pain frequency (OR 39.2, 95% CI 18.8, 81.9) and pain intensity (OR 21.5, 95% CI 8.7, 52.9) were more strongly associated with prostatitis-like symptoms than urinary symptom score (OR 2.8, 95% CI 1.4, 5.6) or quality of life impact score (OR 4.5, 95% CI 1.9, 10.7). CONCLUSIONS: Although urogenital pain is common among community dwelling men, prostatitis-like symptoms based on the modified questions from the NIH-CPSI are less common. While pain measures may be useful in distinguishing between men with and without prostatitis-like symptoms, the urinary symptom and quality of life impact scores could partly reflect benign prostatic hyperplasia.     

Predictors of mortality in adult trauma patients: the physiologic trauma score is equivalent to the Trauma and Injury Severity Score

Background:

Several statistical models (Trauma and Injury Severity Score [TRISS], New Injury Severity Score [NISS], and the International Classification of Disease, Ninth Revision-based Injury Severity Score [ICISS]) have been developed over the recent decades in an attempt to accurately predict outcomes in trauma patients. The anatomic portion of these models makes them difficult to use when performing a rapid initial trauma assessment. We sought to determine if a Physiologic Trauma Score, using the systemic inflammatory response syndrome (SIRS) score in combination with other commonly used indices, could accurately predict mortality in trauma.

Study Design:

Prospective data were analyzed in 9,539 trauma patients evaluated at a Level I Trauma Center over a 30-month period (January 1997 to July 1999). A SIRS score (1 to 4) was calculated on admission (1 point for each: temperature >38°C or <36°C, heart rate >90 beats per minute, respiratory rate >20 breaths per minute, neutrophil count > 12,000 or < 4,000. SIRS score, Injury Severity Score (ISS), Revised Trauma Score (RTS), TRISS, Glasgow Coma Score, age, gender, and race were used in logistic regression models to predict trauma patients’ risk of death. The area under the receiver-operating characteristic curves of sensitivity versus 1-specificity was used to assess the predictive ability of the models.

Results:

The study cohort of 9,539 trauma patients (of which 7,602 patients had complete data for trauma score calculations) had a mean ISS of 9 ± 9 (SD) and mean age of 37 ± 17 years. SIRS (SIRS score ≥ 2) was present in 2,165 of 7,602 patients (28.5%). In single-variable models, TRISS and ISS were most predictive of outcomes. A multiple-variable model, Physiologic Trauma Score combining SIRS score with Glasgow Coma Score and age (Hosmer-Lemenshow CHI-SQUARE = 4.74) was similar to TRISS and superior to ISS in predicting mortality. The addition of ISS to this model did not significantly improve its predictive ability.

Conclusions:

A new statistical model (Physiologic Trauma Score), including only physiologic variables (admission SIRS score combined with Glasgow Coma Score and age) and easily calculated at the patient bedside, accurately predicts mortality in trauma patients. The predictive ability of this model is comparable to other complex models that use both anatomic and physiologic data (TRISS, ISS, and ICISS).     

Bleeding complications precipitated by unrecognized Gingko biloba use after liver transplantation

Because of its neurocognitive enhancing effects, Gingko biloba has emerged as amongst the most commonly used herbal products. We report a liver transplant recipient with potentially life-threatening toxicity resulting from Gingko biloba use. Seven days after a second liver transplantation for recurrent hepatitisB virus infection, subphrenic hematoma was documented in a 59-year-old Korean patient. Failure to control bleeding with CT-guided drainage necessitated exploratory laparotomy for the evacuation of a large subphrenic hematoma. Three weeks later, an episode of vitreous hemorrhage was documented. Unbeknownst to his care providers, the patient had been consuming Gingko biloba throughout the postoperative period. No further bleeding episodes occurred after the cessation of Gingko biloba use. Unrecognized use of herbal products may be associated with serious side effects and adverse clinical sequelae in transplant recipients. Given their increasing popularity, the use of herbal products should be routinely sought as part of the history in transplant recipients.     

Should suspected early gallbladder cancer be treated laparoscopically?

Early gallbladder cancer (EGC), defined as T1 and T2 disease, is frequently curable when completely excised without bile spillage. The objective of the present study was to determine what effect initial laparoscopic cholecystectomy has on outcome in patients with EGC. Of 89 patients referred to our institution with gallbladder cancer over an 11-year period, 26 had undergone initial laparoscopic cholecystectomy. Sixteen of the 26 patients had T1 or T2 disease and are the subjects of this report. These patients were reviewed retrospectively to assess preoperative diagnosis, intraoperative bile spillage, and outcome (recurrence and survival). In addition, the Western literature was reviewed to determine the impact of initial laparoscopic cholecystectomy on recurrence and survival of patients with EGC. Six patients had a preoperative ultrasound consistent with a mass in the gallbladder wall. Seven (44%) had documented bile spillage during the laparoscopic cholecystectomy. T stage based on the laparoscopic cholecystectomy was T1 (n = 1) and T2 (n = 15). Twelve patients underwent reexploration of whom seven underwent further radical excision (gallbladder liver bed resection and extensive lymphadenectomy). After a mean follow-up of 20.1 months (range 4 to 39 months), 69% of patients have had a recurrence or died. Three patients had a port-site recurrence. Five (71%) of seven patients with bile spillage at laparoscopic cholecystectomy have had a recurrence or died of disease. A review of the Western literature on EGC initially removed by laparoscopic cholecystectomy (including the present series) yielded 21 patients with T1 and 42 patients withT2 disease. One-year Kaplan-Meier survival (T1 = 89%, T2 = 71%) and 3-year Kaplan-Meier survival (T1 = 47%, T2 = 40%) of these patients is worse than prior reports for open cholecystectomy. An initial laparoscopic cholecystectomy with its potential for bile spillage can convert potentially curable EGC to incurable disease. Patients with preoperative findings suspicious for gallbladder cancer should undergo open exploration with intent to perform a radical cancer operation as a primary procedure if the diagnosis is confirmed intraoperatively.
