Adjuvant radiotherapy throughout ridiculously full resected grade II atypical meningiomas. A safety effect on repeat? A systematic evaluate as well as meta-analysis.
Acoustic Neuroma (AN) is a benign tumour of the eighth cranial nerve. Stereotactic Radiosurgery (SRS) is a common treatment approach. Studies have explored the primary effects of SRS and documented equivalent efficacy for tumour control compared to neurosurgery.

Examine the longer term cognitive and psychosocial outcomes of SRS in non-Neurofibromatosis Type II patients utilising both objective and subjective cognitive outcomes associated with quality of life and health related distress.

Nineteen individuals treated via SRS were assessed using a battery of standardised psychometric tests as well as measures of quality of life and psychological distress.

Participants had largely preserved cognitive function except for processing speed, aspects of attention and visual memory relative to age norms. Self-reported quality of life was better than in other AN population studies. Level of psychological distress was equivalent to general population norms. More than half of participants reported subjective cognitive decline though this was not fully supported by objective testing. Subjective cognitive complaints may be associated with lower reported quality of life.

Results are largely consistent with previous findings on the effects of SRS in other clinical groups, which supports SRS as a targeted radiation treatment for AN.

Spasticity is common in cerebral palsy and can result in pain and diminished health-related quality of life.

To evaluate the safety and efficacy of onabotulinumtoxinA for lower limb spasticity treatment in children with cerebral palsy.

In this registrational phase 3, multinational, randomized, double-blind, placebo-controlled trial (NCT01603628), children (2-< 17 years) with cerebral palsy and ankle spasticity (Modified Ashworth Scale-Bohannon [MAS] score≥2) were randomized 1  1  1 to standardized physical therapy and onabotulinumtoxinA (4 or 8 U/kg), or placebo. Primary endpoint was average change from baseline at weeks 4 and 6 in MAS ankle score. Secondary endpoints included the Modified Tardieu Scale (MTS) and Global Attainment Scale (GAS).

381 participants were randomized. MAS scores averaged at weeks 4 and 6 were significantly reduced with both onabotulinumtoxinA doses (8 U/kg -1.06, p = 0.010; 4 U/kg -1.01, p = 0.033) versus placebo (-0.8). Significant improvements in average dynamic component of spasticity, measured by MTS, and in function, measured by GAS, were observed at several time points with both onabotulinumtoxinA doses versus placebo. Most adverse events were mild or moderate.

OnabotulinumtoxinA was well tolerated and effective in reducing lower limb spasticity and improving functional outcomes versus placebo in children.

Hyperbilirubinemia is a common problem in neonates. The aim of this study was to evaluate the effect of synbiotic in addition to routine phototherapy on the treatment of neonatal jaundice.

This double-blind clinical trial, was performed on 194, 3-14 days old neonates. Neonates were divided into intervention and placebo groups. The intervention group received 5 drops of oral synbiotic daily along with phototherapy and the placebo group underwent phototherapy plus a placebo. Gestational age, age, weight, sex, initial and daily bilirubin level, frequency of defecation, mode of delivery, and length of hospitalization were assessed.

The rate of bilirubin reduction on the first day of admission was significantly higher in the intervention group (2.9±1.81 vs. 2.06±1.93, p = 0.002). BV-6 The mean level of bilirubin on the second (9.8±1.92 vs. 10.88±2.26) and third days (8.06±1.54 vs. 9.86±1.7) was lower in the intervention group (p = 0.001). The proportion of discharged patients in the third and fourth days was higher in the intervention group compared to the control (65% vs. 41%, 99% vs. 86.5%, respectively, p = 0.001). However, the duration of hospitalization was shorter in the intervention group compared to the control (2.36±0.5 vs. 2.74±0.74, p = 0.001).

Based on our results, daily treatment with 5 drops of synbiotic along with phototherapy can be a safe and effective modality in faster bilirubin reduction, decreasing the hospitalization period and phototherapy. Therefore, it seems that it can be used as an adjunct therapy for neonates with jaundice.

Parkinson's disease (PD) is a relentless, chronic neurodegenerative disease characterized by the progressive loss of substantia nigra (SN) neurons that leads to the onset of motor and non-motor symptoms. Standard of care for PD consists of replenishing the loss of dopamine through oral administration of Levodopa; however, this treatment is not disease-modifying and often induces intolerable side effects. While the etiology that contributes to PD is largely unknown, emerging evidence in animal models suggests that a significant reduction in neuroprotective Protein Kinase A (PKA) signaling in the SN contributes to PD pathogenesis, suggesting that restoring PKA signaling in the midbrain may be a new anti-PD therapeutic alternative.

We surmised that pharmacological activation of PKA via intraperitoneal administration of Forskolin exerts anti-PD effects in symptomatic PTEN-induced kinase 1 knockout (PINK1-KO), a bona fide in vivo model of PD.

By using a beam balance and a grip strength analyzer, we show that Forskolin reverses motor symptoms and loss of hindlimb strength with long-lasting therapeutic effects (>  5 weeks) following the last dose.

In comparison, intraperitoneal treatment with Levodopa temporarily (24 h) reduces motor symptoms but unable to restore hindlimb strength in PINK1-KO rats. By using immunohistochemistry and an XF24e BioAnalyzer, Forskolin treatment reverses SN neurons loss, elevates brain energy production and restores PKA activity in SN in symptomatic PINK1-KO rats.

Overall, our collective in vivo data suggest that Forskolin is a promising disease-modifying therapeutic alternative for PD and is superior to Levodopa because it confers long-lasting therapeutic effects.

Motor phenotype (MP) can be associated with a different prognosis in Parkinson's disease (PD), but it is not fixed and can change over time.

Our aim was to analyze how the MP changed over time and to identify factors associated with the changes in PD patients from a multicenter Spanish PD cohort.

PD patients who were recruited from January-2016 to November-2017 (baseline visit; V0) and evaluated again at a 2-year±30 days follow-up (V2) from 35 centers of Spain from the COPPADIS cohort, were included in this study.MP was calculated at both visits based on Jankovic classification in TD (tremor dominant), IND (indeterminate), or PIGD (postural instability and gait difficulty). Sociodemographic and clinical data were collected, including serum biomarkers.

Five hundred eleven patients (62.57±8.59 years old; 59.2%males) were included in the study. At V0, MP was 47.4%(242/511) TD; 36.6%(187/511) PIGD; 16%(82/511) IND. Up to 38%(194/511) of the patients changed their phenotype from V0 to V2, being the most frequent from TD to IND (8.4%) and from TD to PIGD (6.7%). A worse cognitive status (OR = 0.966) and less autonomy for activities of daily living (OR  =  0.937) at V0 and a greater increase in the globalNMS burden (OR  =  1.011) from V0 to V2 were associated with changing from TD to another phenotype after 2-year follow-up.

The MP in PD can change over time. With disease progression, the percentage of cases with non-tremoric MP increases. PD patients who changed from TD to postural instability and gait difficulty increased NMS burden significantly.

MAO-B inhibitor monotherapy has been shown to be effective and safe for the treatment of early-stage PD, while MAO-B inhibitors as adjuvant drugs have been widely applied for the treatment of the advanced stages of the illness. MAO-B inhibitors can effectively improve patients' motor and non-motor symptoms, reduce "OFF" time, and may potentially prevent/delay disease progression. In this review, we discuss the effects of MAO-B inhibitors on motor and non-motor symptoms in PD patients, their mechanism of action, and the future development of MAO-B inhibitor therapy.Presence of plaque and coronary artery stenosis are the main causes of coronary heart disease. Detection of plaque and coronary artery segmentation have become the first choice in detecting coronary artery disease. The purpose of this study is to investigate a new method for plaque detection and automatic segmentation and diagnosis of coronary arteries and to test its feasibility of applying to clinical medical image diagnosis. A multi-model fusion coronary CT angiography (CTA) vessel segmentation method is proposed based on deep learning. The method includes three network layer models namely, an original 3-dimensional full convolutional network (3D FCN) and two networks that embed the attention gating (AG) model in the original 3D FCN. Then, the prediction results of the three networks are merged by using the majority voting algorithm and thus the final prediction result of the networks is obtained. In the post-processing stage, the level set function is used to further iteratively optimize the results of network fusion prediction. The JI (Jaccard index) and DSC (Dice similarity coefficient) scores are calculated to evaluate accuracy of blood vessel segmentations. Applying to a CTA dataset of 20 patients, accuracy of coronary blood vessel segmentation using FCN, FCN-AG1, FCN-AG2 network and the fusion method are tested. The average values of JI and DSC of using the first three networks are (0.7962, 0.8843), (0.8154, 0.8966) and (0.8119, 0.8936), respectively. When using new fusion method, average JI and DSC of segmentation results increase to (0.8214, 0.9005), which are better than the best result of using FCN, FCN-AG1 and FCN-AG2 model independently.Parabolic monocapillary X-ray lens (PMXRL) is an ideal optical device for constraining the point divergent X-ray beams to quasi-parallel beams, but the overlap of direct X-rays and reflected X-rays through PMXRL deteriorates the outgoing beam divergence. Aiming to solve this problem, this study designs and tests a square-shaped lead occluder (SSLO) embedded in PMXRL to block the direct X-rays passing through the PMXRL. Python simulations are employed to determine the geometric parameters of the SSLO as well as the optimal position of the SSLO in the PMXRL according to our proposed model. The PMXRL with a conic parameter p of 0.000939 mm and a length L of 60.8 mm is manufactured and the SSLO with a size of 0.472 mm×0.472 mm×3.4 mm is embedded into it. An optical path system based on this PMXRL is built to measure the divergence of the outgoing X-ray beam. The experimental results show that the quasi-parallel X-ray beam reaches a divergence of 0.36 mrad in the range from 15-45 mm at the PMXRL outlet. This divergence is 10 times lower than the theoretical divergence without SSLO.
