Impaired cerebrovascular reactivity appears to be linked to worse global outcome in adult traumatic brain injury (TBI). Literature suggests that current treatments administered in TBI care, in the intensive care unit (ICU), fail to greatly impact recorded cerebrovascular reactivity measures. In particular, the impact of sedation on cerebrovascular reactivity in traumatic brain injury (TBI) remains unclear in vivo. The goal of this study was to preliminarily assess the relationship between objectively measured depth of sedation and cerebrovascular reactivity in TBI.
Within, we describe a case series of 5 adult TBI patients with TBI, during which objective high-frequency physiology for sedation depth, using bispectral index (BIS), and both intracranial pressure (ICP) and arterial blood pressure (ABP) were recorded. Zilurgisertib fumarate manufacturer Pressure reactivity index (PRx) and RAP (a metric of cerebral compensatory reserve) were derived. Relationships between cerebrovascular reactivity and compensatory reserve monitoring with BIS metr physiology in TBI is required.
The external ventricular drain (EVD) placement is one of the most common neurosurgical procedures. This operation is performed by freehand technique in the majority of cases; therefore, the operator's experience plays an important role in success and possible morbidity of this procedure.
To evaluate the accuracy and safety of EVD placement by junior neurosurgery residents and factors predicting accuracy of EVD placement.
This is a prospective cohort study conducted at our academic medical center, between September 2017 and August 2018. All patients 18years or older who required EVD placement were included. The accuracy and complications of EVD placement were assessed in the first and second year resident cohorts as well as by their level of experience, using descriptive statistics. Univariate and multivariate models were used to assess predictive factors for optimal EVD.
A total of 100 EVDs were placed in 100 patients during the study period. According to Kakarla classification, the catheter was optimally placed in 80% of cases. The first year residents had a significantly higher rate of suboptimal burr hole placement compared to the second year residents (66.7% versus 27.1%, p = 0.004). The trainees with less than 10 EVD placement experience also had a significantly higher rate of suboptimal burr hole placement (55.2% vs. 23.9%, p = 0.003), significantly longer duration of operation (43.1min ± 14.9SD vs 34.2min ± 9.6 p = 0.005), and significantly lower rate of optimal EVD location (85.9% versus 65.5%, p = 0.023). Optimal location of the burr hole was the only significant predictor of optimal EVD placement in multivariate analysis (OR 11.9, 95% CI 3.2-44.6, p < 0.001).
Neurosurgery residents experience and optimal burr hole placement are the main predicators of accurate EVD placement.

Entrapment of the middle cluneal nerve (MCN), a peripheral nerve in the buttock, can elicit low back pain (LBP). We examined the epidemiology, clinical course, and treatment of MCN entrapment (MCN-EN).
Among 383 LBP patients who visited our institute, 105 were admitted for intractable LBP. They were 42 men and 63 women; their average age was 64 years. Based on clinical symptoms, palpation, and the effects of MCN block, we suspected MCN-EN in these 105 patients, 50 of whom are our study subjects. Their treatment outcomes were assessed at the time of discharge and at follow-up visits.
MCN-EN was diagnosed in 50 of the 383 patients (13.1%) and they were hospitalized. In 43 (11.2%), MCN-EN was associated with other diseases (superior cluneal nerve entrapment, n = 21, sacroiliac joint pain, n = 9, other, n = 13). At the time of discharge, the symptoms of patients with LBP due to MCN-EN were significantly improved by repeat MCN blocks. In 7 of the 383 patients (1.8%), LBP was improved by only MCN blocks; 5 of surgery, the presence of MCN-EN must be ruled out.
Cases of systemic thromboembolism due to thrombus formation in the pulmonary vein stump after lobectomy have been reported recently. Cerebral infarction after left upper lobectomy is a common symptom in these cases. We encountered a rare case of acute limb ischemia caused by a thrombus formed in the left inferior pulmonary vein stump after left lower lobectomy.
A 62-year-old man underwent video-assisted left lower lobectomy under general anesthesia with epidural anesthesia. On postoperative day 2, he suddenly developed pain in the left calf. Contrast-enhanced computed tomography showed left popliteal artery occlusion and thrombus formation in the left inferior pulmonary vein stump. Anticoagulant therapy was started immediately, and emergent endovascular thrombectomy was performed. The patient recovered without complications.
Left lower lobectomy can cause thrombus formation in the pulmonary vein stump, leading to systemic thromboembolism. Early detection and treatment are the keys to minimize complications.

L. mucosae showed the best survivability and stability of the studied lactobacilli after processing and during storage, respectively, and also remarkably influenced the texture and sensory features of desserts in comparison to the other strains; L. plantarum achieved viability comparable with the commercial probiotic, above 6 log cfu/g up to the 21st day of the products refrigerated storage. The hydroethanolic extract and syrup from the jabuticaba peel contributed to the phenolic content of the dairy desserts (around 30 mg GAE/100 g) that showed to be able to scavenge DPPH radicals (around 300 g dessert/g DPPH). The different lactobacilli strains did not significantly influence the antioxidant capacity parameters of the desserts (p > 0.05), although the desserts' color was not stable during storage and tended to reduce the acceptability scores of the three trials. Non-fermented dairy desserts with jabuticaba peel ingredients showed to be good sources of phenolic compounds with an antioxidant capacity, offering suitable conditions for the viability maintenance of the autochthonous lactobacilli cultures.Nisin is a promising therapeutic candidate because of its potent activity against Gram-positive bacteria. The present study aimed to describe the in vitro and in vivo antibacterial effects of nisin against Streptococcus suis, an important zoonotic pathogen. The minimal inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs) of nisin against different S. suis strains ranged from 0.12 to 4.0 μg/mL and from 0.25 to 8.0 μg/mL, respectively. link2 Time-killing curve assays illustrated that nisin killed 100% of tested virulent S. link3 suis strains within 4 h when used at 2× MIC, which indicates the rapid bactericidal activity of nisin against the bacteria. Transmission and scanning electron microscopy revealed that nisin destroyed S. suis cell membrane integrity and affected its cellular ultrastructure, including a significantly wrinkled surface, intracellular content leakage, and cell lysis. In addition, nisin inhibited biofilm formation by S. suis in a concentration-dependent manner and exhibited strong degrading activities against preformed biofilms. More importantly, nisin displayed antimicrobial activity against S. suis infection in vivo. Upon treatment with 5.0-10 mg/kg nisin solution, the survival rates of mice challenged with a lethal dose of virulent S. suis virulent ranged 87.5-100%. Nisin significantly decreased bacterial proliferation and translocation in the mouse spleen, brain, and blood. These results indicate that nisin has potential as a novel antimicrobial agent for the clinical treatment and prevention of infection caused by S. suis in animals.Several studies have reported that probiotics could modulate host lipid metabolism via altering the intestinal microbiota. Hence, the current study was aimed to assess the efficacy of a mixture of probiotic-contained milk formula (PMF) with three different bacterial strains [Lactobacillus acidophilus (La5), Lactobacillus casei (TMC), Bifidobacterium lactis (Bb12)] on lipid profile and intestinal function in healthy mild hypercholesterolemic volunteers. Totally, 40 healthy mild hypercholesterolemic subjects (180-220 mg/dL) were randomly assigned into two groups as placebo or experimental group. All the subjects were requested to drink either PMF (experimental) or skimmed milk drink formula-placebo (30 g mixed with 200 mL of water) for 10 weeks and continued by 2 weeks of the follow-up period. Supplementation of PMF for 10 weeks significantly improved (p less then 0.05) the fecal weight, fecal movement (decreased fecal gastrointestinal passing time) by improving intestinal microbiota (increasing beneficial bacterial species like Lactobacillus, Bifidobacterium spp.), and lag time of low-density lipoprotein (LDL) oxidation. Also, intake of PMF substantially reduced (p less then 0.05) the levels of total cholesterol (TC; 8.1%) and low-density lipoprotein cholesterol (LDL-c; 10.4%) and thus showcasing its cardioprotective efficacy. PMF considerably improves gastrointestinal function by modulating fecal movement, intestinal microbiota, and decrease cholesterol and might be helpful in the management of hypercholesterolemia.Urolithin A (Uro-A), a metabolite of ellagitannins in mammals' intestinal tract, displays broad biological properties in preclinical models, including anti-oxidant, anti-inflammatory, and anti-tumor effects. However, the clinical application of Uro-A is restricted because of its low aqueous solubility and short elimination half-life. Our purpose was to develop a delivery system to improve the bioavailability and anti-tumor efficacy of Uro-A. To achieve this goal, urolithin A-loaded PEGylated liposomes (Uro-A-PEG-LPs) were prepared for the first time and its physicochemical properties and anti-tumor efficacy in vitro were evaluated. The morphology of Uro-A-PEG-LPs displayed a uniform sphere under transmission electron microscope. The particle size, polydispersity index, zeta potential, and encapsulation efficiency of Uro-A-PEG-LPs were 122.8 ± 7.4 nm, 0.25 ± 0.16, - 25.5 ± 2.3 mV, and 94.6 ± 1.6%, respectively. Moreover, Uro-A-PEG-LPs possessed higher stability and could be stably stored at 4°C for a long time. In vitro release characteristics indicated that Uro-A-PEG-LPs possessed superior sustained release properties. The results of confocal laser scanning microscopy experiment showed that the coumarin 6-loaded PEGylated liposomes (C6-PEG-LPs) have superior cellular uptake than that of conventional liposomes. In addition, in vitro tests demonstrated that Uro-A-PEG-LPs elevated cytotoxicity and pro-apoptotic effect in human hepatoma cells comparing with free Uro-A. Furthermore, the results of pharmacokinetic experiments showed that the t1/2, AUC0-t, and MRT0-t of Uro-A-PEG-LPs increased to 4.58-fold, 2.33-fold, and 2.43-fold than those of free Uro-A solution, respectively. Collectively, these manifested that PEGylated liposomes might be a potential delivery system for Uro-A to prolonging in vivo circulation time, promoting cellular uptake, and enhancing its anti-tumor efficacy.
