HAPPILEE: HAPPE In Low Electrode Electroencephalography, a standardized pre-processing software for lower density recordings.

Lower-density Electroencephalography (EEG) recordings (from 1 to approximately 32 electrodes) are widely-used in research and clinical practice and enable scalable brain function measurement across a variety of settings and populations. Though a number of automated pipelines have recently been proposed to standardize and optimize EEG pre-processing for high-density systems with state-of-the-art methods, few solutions have emerged that are compatible with lower-density systems. However, lower-density data often include long recording times and/or large sample sizes that would benefit from similar standardization and automation with contemporary methods. To address this need, we propose the HAPPE In Low Electrode Electroencephalography (HAPPILEE) pipeline as a standardized, automated pipeline optimized for EEG recordings with lower density channel layouts of any size. HAPPILEE processes task-free (e.g., resting-state) and task-related EEG (including event-related potential data by interfacing with the HAPPE+ER pipeline), from raw files through a series of processing steps including filtering, line noise reduction, bad channel detection, artifact correction from continuous data, segmentation, and bad segment rejection that have all been optimized for lower density data. HAPPILEE also includes post-processing reports of data and pipeline quality metrics to facilitate the evaluation and reporting of data quality and processing-related changes to the data in a standardized manner. Here the HAPPILEE steps and their optimization with both recorded and simulated EEG data are described. HAPPILEE's performance is then compared relative to other artifact correction and rejection strategies.

A whole-person sampler for assessing numbers of host-seeking adult mosquitoes.

The whole-person bag sampler (WPBS) is a human-baited drop-net mosquito trap for evaluating an individual's exposure to nuisance mosquitoes. A diagram of WPBS construction is given, with results from field tests. Trap operator exposures of 2, 4, and 8 min did not result in a corresponding increase in mosquitoes caught in the WPBS, although simultaneous captures using a sweep net or Nasci aspirator increased with the sample duration. The person baiting and operating the trap did not have a significant effect on number of mosquitoes captured. Taxonomic diversity of adult mosquitoes collected with WPBS and CO2-baited traps was similar, with Aedes vexans predominant in the study areas.

Continuing care for the near-drowning child.

The continuing care for a child survivor of a near-drowning accident presents a variety of challenges for the tertiary-care setting, community-based health care providers, and especially the family. The trauma the child receives from this type of neurologic insult coupled with the emotional issue of an accident such as a near drowning result in a long-term, usually lifetime situation of great stress and responsibilities for the family. Although long-term hospitalization is usually required for medical stabilization of the child, survivors of this type of injury will require some kind of continuing care outside of the hospital setting. In most instances, pediatric home care offers a reasonable alternative for the family. In the provision of skilled nursing support in the child's home environment, their medical needs can be met effectively. Additionally, home care offers a strong support to the families and can assist in fostering the long-term care environment parents must face if they are to successfully provide for their child at home. Planning for the child's discharge to home involves a comprehensive and coordinated approach to providing a community-based support network of care for the child and family. Additionally, parents must learn complicated, technical skills to meet the physical needs of their child. This process requires careful planning and implementation. During this time the hospital will assist the family in procuring the community-based services they will need. Once the child is discharged, the family focus is directed toward establishing positive work partnerships with the other service providers necessary to assist them in the care of their child. This process takes considerable planning and effort for all involved but, when successful, facilitates a positive, nurturing home care environment. The family remains the guiding force in this situation and ultimately determines if their child's care at home will be successful. In this context, success is not measured by recovery or cure but, instead, by the degree of enhancement the family receives in providing home-based care. The role of the home care nurse is an important one and is comprehensive in scope and responsibilities. The nurse not only delivers skilled care and treatment to the child but also offers support and assistance to the family. These home care nurses must be highly skilled and trained in the delivery of complex medical care and effectively provide the emotional and psychological support families of these children demand. An equally important function of the home care nurse is that of family advocate.(ABSTRACT TRUNCATED AT 400 WORDS)

Electrolytic preconcentration in instrumental analysis.

The use of electrolytic deposition as a separation and preconcentration step in trace metal analysis is reviewed. Both the principles and applications of the technique are dealt with in some detail. Electrolytic preconcentration can be combined with a variety of instrumental techniques. Special attention is given to stripping voltammetry, potentiometric stripping analysis, different combinations with atomic-absorption spectrometry, and the use of flow-through porous electrodes. It is pointed out that the electrolytic preconcentration technique deserves more extensive use as well as fundamental investigation.
