The Nosographic Structure of Posttraumatic Stress Symptoms across Different Types of Trauma: An Exploratory Network Analysis Approach

Abstract The nosographic structure of posttraumatic stress disorder (PTSD) remains unclear, and attempts to determine its symptomatic organization have been unsatisfactory. Several explanations have been suggested, and the impact of trauma type is receiving increasing attention. As little is known about the differential impact trauma type in the nosographic structure of PTSD, we explored the nosology of PTSD and the effect of trauma type on its symptomatic organization. We reanalyzed five cross-sectional psychopathological networks involving different trauma types, encompassing a broad range of traumatic events in veterans, war-related trauma in veterans, sexual abuse, terrorist attacks, and various traumatic events in refugees.

Contrasting protist communities (Cercozoa: Rhizaria) in pristine and earthworm-invaded North American deciduous forests

Abstract Earthworms are considered ecosystem engineers due to their fundamental impact on soil structure, soil processes and on other soil biota. An invasion of non-native earthworm species has altered soils of North America since European settlement, a process currently expanding into still earthworm-free forest ecosystems due to continuous spread and increasing soil temperatures owing to climate change. Although earthworms are known to modify soil microbial diversity and activity, it is as yet unclear how eukaryote consumers in soil microbial food webs will be affected.

Identifying Treatment Targets in Idiographic Psychopathological Networks: A Simulation Study

Following current trends for precision medicine, psychology has in recent years turned its attention to treatment personalization. Several technological and methodological advances have contributed to this renewed focus on psychology. One of these methodological advances at the center of this push toward precision medicine is network analysis. One of the core propellers of the network theory of psychopathology is the proposal that highly influential symptoms of the network (i.e., central symptoms) might be promising treatment targets. However, evidence for this proposal remains inconclusive, with evidence from idiographic longitudinal assessments lacking. In this study, we explore the impact of symptom deactivation in individual networks (named idiographic networks). We tested two types of symptom deactivation: normal and cascade attack, and five measures for highly influential symptom identification (degree, strength, eigenvector, expected influence, and random attack condition). We find that a cascade degree-based attack is more effective at deactivating the symptom network, we next discuss the implications for treatment personalization and precision psychology.

Honey bee virus causes context-dependent changes in host social behavior

The increase in human population has fueled demand for pollination services; the resulting intensification and globalization of honey bee management has coincided with increased pathogen pressure. We hypothesized that Israeli acute paralysis virus (IAPV) can alter host social behavior, predicting different behavioral changes depending on social context.

Combined Experimental and System-Level Analyses Reveal the Complex Regulatory Network of miR-124 during Human Neurogenesis

Using RNA-induced-silencing-complex precipitation, we identified 98 high-confidence miR-124 targets, of which some directly led to decreased viability. By performing advanced transcription-factor-network analysis, we identified indirect miR-124 effects on apoptosis, neuronal subtype differentiation, and the regulation of previously uncharacterized zinc finger transcription factors.

Measuring hand hygiene compliance rates at hospital entrances

Abstract Despite the importance of hand hygiene in the health care setting, there are no studies evaluating hand hygiene compliance at hospital entrances. The study was prospectively performed over a 33-week period from March 30, 2014-November 15, 2014, to evaluate hand hygiene compliance in 2 hospital reception areas. We compared electronic handwash counters with the application of radiofrequency identification (GOJO SMARTLINK) (electronic observer) that counts each activation of alcohol gel dispensers to direct observation (human observer) via remote review of video surveillance.
