Varicella-zoster virus (VZV) infections cause a substantial disease burden, which is underestimated due to incomplete reporting data and lack of serological surveillance. In this post-hoc analysis of a randomized, Phase IIIb clinical trial (NCT00226499) with a ten-year follow-up period, we report anti-VZV antibody levels and persistence in non-vaccinated children, as a varicella infection estimate in ten European countries with endemic varicella. The present analysis specifically focuses on clinical and serological data from the control group, which included 827 healthy participants aged 12-22 months who received two doses of measles-mumps-rubella (MMR) vaccine. The per-protocol cohort included 744 children for whom varicella occurrence was evaluated by clinical definitions, epidemiological links and PCR test outcomes. Anti-VZV antibody levels were assessed by ELISA. The primary objective of this analysis was to correlate varicella occurrence with anti-VZV antibody levels. Varicella was confirmed in 47% of MMR recipients. Among participants without reported varicella, the percentage of anti-VZV seropositive children increased to 75% and average anti-VZV antibody concentrations increased to 250 mIU/mL at year ten after vaccination, suggesting infection or exposure. An eight-fold increase in anti-VZV antibody concentrations between two consecutive visits, which is also observed after confirmed varicella, was detected in 37% of these participants during the follow-up period. About one-third of children not vaccinated against varicella and not diagnosed with varicella developed an anti-VZV immune response, suggesting subclinical varicella occurrence. Longitudinal studies combining serology and disease incidence are necessary to reliably estimate total varicella burden of infection.

Stroke impacts psychosocial well-being and engagement in occupation. Psychosocial interventions reduce depression and anxiety but may not impact occupation. read more Knowledge of key processes and components of community psychosocial stroke interventions can inform future intervention development.

To determine the essential elements common to three psychosocial interventions for stroke survivors.

Concept maps were created for three community psychosocial stroke interventions based on published literature and communication with researchers who tested the intervention with stroke survivors. The concept maps were then compared to identify common elements. Ongoing communication with researchers ensured accurate representation of each respective intervention.

Similarities in intervention processes and components included support for autonomy; individualized information exchange; coping, life skill development and adaptation support; competence development; and the incorporation of goals. Differences included intervention delivery (individual versus group), and the avenues in which psychosocial needs are addressed (occupation versus dialogue).

Concept mapping identified similarities among the three interventions that can be best understood using self-determination theory. Clinicians may utilize findings revealed in the process to inform evidence-based psychosocial stroke interventions.

Knowledge of key 'active ingredients' for psychosocial community stroke interventions, can be used to guide clinical reasoning and inform development of interventions.

An injection solution is required to create a submucosal cushion (SMC) for safe endoscopic resection procedures. The aim of this preliminary animal study was to clarify the safety and efficacy of a novel fully synthetic and self-assembled peptide (FSSP) solution as a submucosal injection material (SMIM).

To compare the submucosal-lifting properties, 0.3% FSSP, Eleview

, sodium hyaluronate acid solution (SHA) and normal saline (NS) were randomly injected using an injection needle into the submucosa of exposed stomach and colon in five living dogs in a blind fashion. The mean height, and volume of SMCs were measured using a digital caliper immediately and 10, 20, 30, and 40 min after injecting each solution. All resected specimens were examined histopathologically.

In both the colon and stomach, ANOVA for repeated measures showed the significant interaction between time and solution for the time-dependent change in the height. In the colon, FSSP created significantly higher SMC than NS 20 min after injection (

 = .0015) and Eleview

and NS 40 min after injection (

 = .0009 and

 = .0002). Furthermore, FSSP and SHA tended to maintain height and volume when compared to the other two solutions. In the stomach, FSSP and SHA tended to maintain height and volume when compared to the other two solutions. There were no significant differences between the histopathological finding and the injecting solutions used.

FSSP seems to be useful as a SMIM for endoscopic resection especially in the colon. Further studies are needed prior to clinical use of FSSP.

This property of IR is harnessed in the clinic for radiotherapy in almost 50% of cancers patients. Despite the advent of stereotactic radiotherapy instruments and other advancements in shielding techniques, the inadvertent deposition of radiation dose in the surrounding normal tissue can cause late effects of radiation injury in normal tissues. Radioprotectors, which are chemical or biological agents, can reduce or mitigate these toxic side-effects of radiotherapy in cancer patients and also during radiation accidents. The desired characteristics of an ideal radioprotector include low chemical toxicity, high risk to benefit ratio and specific protection of normal cells against the harmful effects of radiation without compromising the cytotoxic effects of IR on cancer cells. Since reactive oxygen species (ROS) are the major contributors of IR mediated toxicity, plethora of studies have highlighted the potential role of antioxidants to protect against IR induced damage.
