A phase III dengue vaccine trial including 9- to 16-year-olds in Latin America (NCT01374516) was ongoing at the time of a Zika outbreak. We explored interactions between dengue and Zika, in the context of dengue vaccination. Symptomatic virologically confirmed Zika (VCZ) was evaluated using acute-phase sera from febrile participants (January 2013-March 2018). Neutralizing antibody geometric mean titers (GMTs) were evaluated pre- and post-Zika outbreak (months 25 and 72) in 2,000 randomly selected participants. Baseline dengue serostatus was determined using the plaque reduction neutralization test or inferred post hoc using nonstructural protein 1 IgG ELISA at M13 (case-cohort analysis). Vaccine efficacy against VCZ and serologically suspected Zika (SSZ) was estimated. Overall, 239/10,157 (2.4%) acute-phase samples were VCZ positive during the study. Dengue vaccine efficacy against VCZ was 27.8% (95% CI 0.3; 47.7) among baseline dengue-seropositive participants. No vaccine effect was evident against SSZ. Zika antibody GMTs increased from pre- to post-Zika epidemic, with smaller increases observed for participants who were dengue seropositive at baseline than for those who were dengue seronegative post-/pre-Zika GMT ratios for baseline dengue-seropositive participants were 21.5 (vaccine group) and 30.8 (placebo); and for dengue seronegatives, 88.1 and 89.5, respectively. Dengue antibody GMTs post-Zika were higher in dengue vaccine and placebo recipients with SSZ than those without SSZ in both dengue seropositives and seronegatives. Dengue vaccine did not enhance symptomatic Zika illness in dengue-seropositive individuals, rather it reduced the risk of VCZ. Zika infection boosted preexisting vaccine-induced or naturally occurring dengue-neutralizing antibodies.Motivated by Edward Zigler's proposition that programs serving children (birth through 12 years) can have long-term effects on well-being and development, we used data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (N = 1,258) to test two pathways by which early care and education (ECE) are linked to after-school organized activities in middle childhood and to problem behaviors in late adolescence and adulthood. In support of an activities pathway, we found children with more ECE hours and more epochs in center-based ECE settings from 1 to 54 months had more epochs in after-school organized activities from kindergarten to 5th grade, which then predicted less impulsivity and less police contact at age 26. In support of a child pathway, we found that more ECE hours and more epochs in center-based ECE settings were linked to externalizing problems in early childhood, which then predicted higher problem behaviors in middle childhood, late adolescence, and adulthood. Together, these pathways underscored the potential of direct and indirect links of ECE and after-school organized activities in relation to later development.All-terrain vehicle (ATV) crashes are one of the leading causes of death and injury in agriculture across the United States. Use of ATVs is highly prevalent in rural areas and has seen an increase in their application for a variety of agricultural work tasks. Empirical research on the use of these vehicles for agricultural tasks and associated injuries is limited, especially in the United States. Moreover, little is known about the risk factors associated with ATV-related injuries while doing farm work. A comprehensive review was conducted to evaluate the current injury burden of ATV use in agriculture, the need for future research, and possible solutions related to agricultural ATV safety. Potential injury prevention approaches are evaluated based on the hierarchy of control, including elimination or substitution (using side-by-side vehicles instead of ATVs or modifying ATV design), engineering control (operator protection devices), administrative authority (regulations and standards in the United States and around the world), training, and use of personal protective equipment. In addition, vehicle nomenclature, risk factors, and crash mechanisms are reviewed. Recommendations to decrease the likelihood of ATV crashes and injuries are provided.

Esophageal bacteria, as the integral composition of human ecosystem, have been reported to be associated with esophageal lesions. However, few studies focus on microbial compositions in different esophageal segments, especially after Lugol's iodine staining (LIS) in the endoscopic examination for the screening of esophageal cancer. We aim to investigate the composition of the bacterial microbiome in upper, middle and lower esophagus and if LIS would affect the detection of bacteria.

A total of 141 fasting samples including the upper, middle and lower esophagus from 27 participants were collected by brushing the mucosal surface of the esophagus before (Eso) and after (Lug) LIS. Bacterial V3-V4 region of 16S rRNA gene was amplified and sequenced by Illumina's sequencing platform.

The top six abundant bacterial phyla taxa among three locations from both Eso and Lug groups were Proteobacteria, Firmicutes, Bacteroidetes, Actinobacteria, Fusobacteria and TM7. In terms of genera, the bacterium in three locations from two groups was all characterized by a highest relative abundance of

. Bacteria diversity and the relative abundance between Eso and Lug were comparable (

 > .05). Bacteria diversity was consistent in different esophageal locations within the individual.

The bacterial microbiome in healthy esophagus are highly diverse and consistent even among three physiological sites at all clades. Lugol's iodine staining would not change local microenvironment in term of microbial composition. These findings provide an essential baseline for future studies investigating local and systemic bacterial microbiome and esophageal diseases.

Whereas the literature has demonstrated an acceptable safety profile of stapled anastomoses when compared to the hand-sewn alternative in open surgery, the choice of intestinal anastomosis using sutures or staples remains inadequately investigated in robotic surgery. The purpose of this study was to compare the surgical outcomes of both anastomotic techniques in robotic-assisted radical cystectomy.

A retrospective analysis of patients with urinary bladder cancer undergoing cystectomy with urinary diversion and with ileo-ileal intestinal anastomosis at a single tertiary centre (2012-2018) was undertaken. The robotic operating time, hospital stay and GI complications were compared between the robotic-sewn (RS) and stapled anastomosis (SA) groups. The only difference between the groups was the anastomosis technique; the other technical steps during the operation were the same. Primary outcomes were GI complications; the secondary outcome was robotic operation time.

There were 155 patients, of which 112 (73%) were male. The median age was 71 years old. Selleckchem CWI1-2 A surgical stapling device was used to create 66 (43%) separate anastomoses, while a robot-sewn method was employed in 89 (57%) anastomoses. There were no statistically significant differences in primary and secondary outcomes between RS and SA.

Compared to stapled anastomosis, a robot-sewn ileo-ileal anastomosis may serve as an alternative and cost-saving approach.

Central venous accesses devices (CVADs) have a fundamental importance for diagnostic and therapeutic purposes in pediatric onco-hematological patients. The treatment of pediatric onco-hematological diseases is complex and requires the use of integrated multimodal therapies. Long-lasting and safe central venous access is therefore a cornerstone for any successful treatment.

The aim of this work is to define pediatric guidelines about the management of CVADs in onco-hematology. A panel of experts belonging to the working groups on Infections and Supportive Therapy, Surgery and Nursing of the Italian Pediatric Hematology Oncology Association (AIEOP) revised the scientific literature systematically, scored the level of evidence and prepared these guidelines. The content of the following guidelines was approved by the Scientific Board of AIEOP.

Important innovations have been developed recently in the field of CVADs, leading to new insertion methods, new materials and new strategy in the overall management of the device, especially in the adult population. These guidelines recommend how to apply these innovations in the pediatric population, and are directed to all physicians, nurses and health personnel active in the daily management of CVADs. Their aim is to update the knowledge on CVAD and improve the standard of care in pediatric patients with malignancies.

The central nervous system adapts strategies to compensate the decreased motor capacities of a fatigued muscle. However, data on neurophysiological adaptations of muscles other than those under fatigue are scarce. The present study was designed to evaluate the effects of submaximal fatiguing contraction (leading to a task failure) induced in ankle dorsiflexors muscles on the excitability of the Hoffmann reflex (H-reflex) of an ankle plantarflexor (soleus muscle).

Twenty-three physically active males (75.5 ± 8.3 kg; 1.77 ± 0.08 m; 27.0 ± 8.0 years) were asked to maintain the contraction level of the right ankle dorsiflexors at 60% of the maximal isometric voluntary contraction (MIVC). Task failure was defined when the force level dropped below 40% MIVC for 5 consecutive seconds. The input-output relation of the ascending limb of the recruitment curve of the soleus H-reflex was examined at 0 min, 5 min, 10 min, 15 min and 20 min after the task failure.

The amplitude parameter representing the first recruited motoneurons (threshold H-reflex - H@th) was significantly higher at 5 min, 10 min, 15 min and 20 min after task failure as compared to control (Hth) (

 < 0.05). On the other hand, the parameter that represents the activation of the relatively higher threshold motoneurons (H@100) was reduced (as compared to control - H100), but only at 20 min after the task failure (

 < 0.05).

These results suggest differential reflex modulation of the soleus H-reflex after fatigue of the ankle dorsiflexors, that probably reflects neuronal adaptations underlying motor control around the ankle joint.
