82 (3.35-6.66) mg/L for 51 mg/kg and 17 mg/kg 8/8 h, respectively. In addition, the area under the curve (AUC

) for plasma and tissue of clindamycin were 44.78 (28.82-65.65) and 16.54 (13.83-18.35) h.mg/L for 51 mg/kg, respectively, and the tissue penetration factor determined was 1.10. Considering that the main bacteria that cause odontogenic infections generally present MIC ≤ 0.5 mg/L, the ƒ%T > MIC index is reached when the dose regimen of 17 mg/kg 8/8 h is employed.

This investigation showed that clindamycin excellently penetrates muscle tissue of rats. It provides effective antibacterial concentrations at the target site when 17 mg/kg 8/8 h is employed and can be applied to treat the main bacteria causing odontogenic infections.

It reinforces the use of clindamycin in odontogenic infections with significant tissue penetration.

The present study examined the extent to which school burnout symptoms (i.e., exhaustion and cynicism) among upper secondary education students have their roots in primary and lower secondary school and whether early antecedents of school burnout symptoms could be identified. The sample consisted of 1544 Finnish students followed up four times (Time1-Time 4) from the end of primary school (T1; mean age 12.74 and range 11.71-14.20) to the first year of upper secondary education (T4; mean age 16.66 and range 15.55-18.39). The results of latent growth curve modeling showed that school burnout symptoms in upper secondary education were predicted by the level of school burnout symptoms at the end of primary school and by an increase in these symptoms across the transition from primary school through lower secondary school. In addition, psychological well-being, academic skills, and gender were found to contribute to the prediction of school burnout symptoms. Overall, the present study suggest that potential warning signs of school burnout should not be ignored and attention should be directed to earlier education phases.The association between late-life depression (LLD) and age-related hearing loss (ARHL) was suggested by preliminary studies, but reliance on LLD subtypes may introduce significant bias. We examined the association between ARHL and LLD according to the age of onset (early-onset depression (EOD) and late-onset depression (LOD)). We investigated the association between ARHL and LLD diagnosed according to the Semi-structured Clinical Diagnostic Interview for DSM-IV-TR in 1749 Italian community-dwelling older subjects from the population-based GreatAGE Study, Southern Italy. Peripheral ARHL was assessed as a pure tone average (PTA) threshold > 40 dB hearing level in the better ear- and age-related CAPD as a score of less then  50% to the Synthetic Sentences Identification with Ipsilateral Competitive Message (SSI-ICM) test. LLD amounted at 10.29% of the sample, subdivided in LOD (6.21%) and EOD (4.08%). Age-related CAPD tended to be higher in LOD (28.91%) than in EOD (19.05%). After accounting for covariates, LOD was tendentially associated to age-related CAPD, but not to peripheral ARHL. This trend was confirmed by the linear models in which LOD was significantly associated to worsen SSI-ICM percentages (odds ratio 2.38, 95% confidence interval 1.32-4.30, p = 0.004), but not to PTA values. In a fully adjusted model of LOD, the effect of the association between CAPD and LOD was explained by social dysfunction. LLD was not associated to peripheral ARHL. 10-Deacetylbaccatin-III datasheet Age-related CAPD was associated to LOD, a form of depression with cognitive dysfunction hallmark. The ARHL assessment may be an important opportunity to prevent depressive disorders in later life, particularly for LOD.

The objective of this study was to investigate whether the use of an anti-reflux catheter improves tumor targeting for colorectal cancer patients with unresectable, chemorefractory liver metastases (mCRC) treated with holmium-166 (

Ho)-radioembolization.

In this perspective, within-patient randomized study, left and right hepatic perfusion territories were randomized between infusion with a Surefire® anti-reflux catheter or a standard microcatheter. The primary outcome was the difference in tumor to non-tumor (T/N) activity distribution. Secondary outcomes included the difference in infusion efficiency, absorbed doses, predictive value of

Ho-scout, dose-response relation, and survival.

Twenty-one patients were treated in this study (the intended number of patients was 25). The median T/N activity concentration ratio with the use of the anti-reflux catheter was 3.2 (range 0.9-8.7) versus 3.6 (range 0.8-13.3) with a standard microcatheter. There was no difference in infusion efficiency (0.04% vs. 0.03% residual activity for the standard microcatheter and anti-reflux catheter, respectively) (95%CI - 0.05-0.03). No influence of the anti-reflux catheter on the dose-response rate was found. Median overall survival was 7.8months (95%CI 6-13).

Using a Surefire® anti-reflux catheter did not result in a higher T/N activity concentration ratio in mCRC patients treated with

Ho-radioembolization, nor did it result in improved secondary outcomes measures.

Lu]Lu-PSMA-617 radioligand therapy (PSMA-RLT) is a new therapy for patients with metastatic castration-resistant prostate cancer (mCRPC). However, identification of reliable prognostic factors is hampered by heterogeneous treatment regimens applied in previous studies. Hence, we sought clinical factors able to predict response and survival to PSMA-RLT in a homogenous group of patients, all receiving 7400MBq every 4weeks.

Data of 61 patients (mean age 71.6 ± 6.9years, median basal PSA 70.7 [range 1.0-4890μg/L]), pretreated with abiraterone/enzalutamide (75.4%) and docetaxel/cabazitaxel (68.9%), received three cycles of PSMA-RLT (mean 7321 ± 592MBq) at four weekly intervals and were analyzed retrospectively. General medical conditions and laboratory parameters of every patients were regularly assessed. Response to therapy was based on PSA levels 1month after the 3rd cycle. Binary logistic regression test and Kaplan-Meier estimates were used to evaluate predictors and overall survival (OS).
