Antibiotic prophylaxis following delayed sternal closure in pediatric cardiac surgery is not standardized. We systematically reviewed relevant literature published between 1990 and 2019 to aid future trial design. Patient characteristics, antimicrobial prophylaxis regimens, and postoperative incidence of infection were collected. Twenty-eight studies described 36 different regimens in over 3,000 patients. There were 11 single-drug regimens and 25 multidrug regimens. Cefazolin-only was the most common regimen (9/36, 25%). The overall incidence of surgical site infection was 7.5% (217/2,910 patients) and bloodstream infection was 7.4% (123/1,667 patients). In the 2010s, multidrug regimens were associated with a significantly lower incidence of both surgical site infections (4.6% vs. 20%, P less then .001) and bloodstream infections (6.0% vs. 50%, P less then .001) compared to single-drug regimens.
Systematic review.

To compare outcomes of complete versus incomplete resection in primary intramedullary spinal cord ependymoma.

A comprehensive search of the MEDLINE, CENTRAL, and Embase databases was conducted by 2 independent investigators. Random-effect meta-analysis and meta-regression with seven covariates were performed to evaluate the reason for the heterogeneity among studies. We also used individual patient data in the integrative analysis to compare complete and incomplete resection based on 4 outcomes progression-free survival (PFS), overall survival (OS), postoperative neurological improvement (PNI), and follow-up neurological improvement (FNI).

A total of 23 studies were identified, including 407 cases. Significant heterogeneity among included studies was observed in risk estimates (I
for PFS, FNI, and PNI were 49.5%, 78.3%, and 87.2%, respectively). The mean follow-up time across cases was 48.6 ± 2.35 months. Cox proportional multivariable analysis revealed that the complete resection can prolong PFS (model, hazard ratio = 0.18, CI 0.05-0.54,
= .004,) and improve the FNI (binary logistic regression, adjusted odds ratio = 16.5, CI 1.6-171,
= .019). However, PNI and OS were similar in patients with incomplete resected spinal cord ependymoma compared with complete resection (binary logistic regression respectively and Cox multivariable analysis,
> .5).

The data presented in this study showed that OS was not significantly affected by the degree of surgery. However, complete resection of intramedullary ependymomas provides the optimal outcomes with longer PFS and better long-term neurological outcomes than incomplete resection.

This study differs in its methodological approach from previously published research by interpreting qualitative results against existing literature to understand how nurses conceptualize medical-surgical patient rooms as productive settings in relation to lighting, as well as the ways in which nurses believe these spaces could be enhanced for patient satisfaction.

Content analysis was used to interpret themes emerging from nurses' subjective responses to open-ended items. Three of the facilities had older, traditional lighting systems; one had a contemporary framework.

A theme of environmental control over both overhead and task lighting emerged from data from all items. Although controllability was among the "best" lighting attributes, more refinement is necessary for optimal staff productivity and patient satisfaction. Daylighting was also considered to be among the best attributes. Control over light level via additional dimming capability for patients, as well as additional light sources, was promiary concern for nurses.In this article, we formulate and study a discrete equation model depicting the pattern of Wolbachia infection in a mosquito population. A domain in [Formula see text] is called a Wolbachia infection enhancing (or decaying) domain if in which the Wolbachia infection frequency of the next generation is always bigger (or smaller) than that of the current generation. We first give a complete analysis of the equivalent Wolbachia infection frequency curves. And then we clearly characterize the Wolbachia infection enhancing domain and decaying domain for all of the parameters, respectively. Finally, some numerical examples are also provided to illustrate our theoretical results.
The novel Coronavirus disease 2019 pandemic is sweeping through China, posing the greatest ever threat to its public health and economy. As a tertiary cancer center in Southwest China, we formulated and implemented an anti-infection protocol to prevent the spread of Coronavirus disease 2019 in our department.

The anti-infection protocol divided patients into 3 categories, namely outpatients, inpatients, and patients receiving radiation therapy at our cancer center, and each category had a distinct anti-infection protocol to minimize the risk of Coronavirus disease 2019 transmission. In each category, the patients were classified into high-, intermediate-, and low-risk groups. Each risk group was managed differently. A survey of patient volume changes prior to and during the Coronavirus disease 2019 outbreak was performed.

We carried out the anti-infection protocol at our cancer center during the Coronavirus disease 2019 outbreak. We found that the total volume of both outpatient visits and inpatient treotocol implemented at our cancer center has been effective in preventing cross-infection. Whether our anti-infection protocol experience can be applied to curb the spread of the infection in other parts of the world remains to be tested.
Post-stroke sitting balance is a known predictor of independence of gait after stroke. However, previous studies used only qualitative scales or measured static or dynamic sitting balance alone.

To investigate whether quantitative parameters of sitting posturography at post-stroke 1month can predict independent gait.

In this prospective cohort study, we enrolled patients with first-ever stroke who could hold a sitting posture at post-stroke 1month. Sitting balance was assessed using posturography at post-stroke 1month. Independence of gait was assessed using functional ambulation categories at post-stroke 2months. We predicted mobility independence at post-stroke 2months according to sitting balance at post-stroke 1month. We also assessed the correlation between sitting posturography parameters and clinical scales.

We enrolled 27 patients. The limit of stability deviation predicted independent gait at post stroke 2months (cutoff, 78.4%). https://www.selleckchem.com/products/iruplinalkib.html Further, there was a high degree of correlation between sitting posturography parameters (weight-bearing distribution deviation and limit of stability deviation) and Berg Balance Scale (
