Symptom frequency and exposure to a cyanobacteria bloom in Florida.

This investigation was undertaken to characterize health effects associated with a major bloom of blue-green algae due to the proliferation Microcystis aeruginosa that occurred in Florida in 2018. Cyanobacteria produce multiple toxins, including the potent hepatotoxic microcystins (MCs), that have been reported to cause illness in exposed persons worldwide. Widespread exposure to toxins released by blue-green algae during the 2018 bloom was shown by the presence of MCs in the nasal passages of 95 percent of the individuals studied previously in south Florida (Schaefer et al.

Measurement of Microcystin Activity in Human Plasma Using Immunocapture and Protein Phosphatase Inhibition Assay.

Microcystins are toxic chemicals generated by certain freshwater cyanobacteria. These chemicals can accumulate to dangerous levels during harmful algal blooms. When exposed to microcystins, humans are at risk of hepatic injury, including liver failure.

International recommendations for an effective control of head louse infestations.

Head louse infestations continue to be a concern of public health in most countries, including the most developed ones. The present recommendations are intended to inform and stress the role and impact of the different authorities, institutions, industry, and the public in the control of head lice in order to reduce the prevalence of this parasite. We encourage health authorities to pursue more effective methods to correctly identify such infestations, and evaluate existing and new pediculicides, medical devices, louse repellents, and louse- and nit-removal remedies.

Perceptions of Breastfeeding for Women with Perinatal Depression: A Descriptive Phenomenological Study.

Women with perinatal depression have an increased risk for breastfeeding cessation, yet few studies have explored their lived experience. In this qualitative study, semistructured interviews were conducted with a purposeful sample of women (N = 10) who self-reported perinatal depression. Using Giorgi's descriptive phenomenological method of data analysis, five components were found to embody their lived experience of breastfeeding: (a) choosing selflessness, (b) harboring inadequacy, (c) deliberate persevering, (d) discerning meaning, and (e) cherishing intimacy.

Narratives of older persons' frailty and physical activity in relation to environmental landscapes and time.

Aims And Objectives: The objective of this study was to explore the influence of the environmental landscape on the physical activity of older persons experiencing frailty.

Background: This manuscript describes the second phase of an unpublished larger study in the northern province of Lampang, Thailand. Phase One revealed that 14% of 1,788 older persons surveyed were found to have experienced frailty according to Fried's frailty phenotypes, and low physical activity was associated with frailty.

The Invisibility of Spiritual Nursing Care in Clinical Practice.

Spirituality has been identified as the essence of being human and is recognized, by many health care professionals, as a central component in health and healing. Scholars have identified spiritual nursing care as essential to nursing practice and include caring for the human spirit through the development of relationships and interconnectedness between the nurse and the patient. However, despite the recognition of spiritual practices as important to health, little attention has been given to spirituality in nursing practice and education in the literature.

Effects of neurofeedback and working memory-combined training on executive functions in healthy young adults.

Given the interest in improving executive functions, the present study examines a promising combination of two training techniques: neurofeedback training (NFT) and working memory training (WMT). NFT targeted increasing the amplitude of individual's upper Alpha frequency band at the parietal midline scalp location (Pz), and WMT consisted of an established computerized protocol with working memory updating and set-shifting components. Healthy participants (n = 140) were randomly allocated to five combinations of training, including visual search training used as an active control training for the WMT; all five groups were compared to a sixth silent control group receiving no training.

NASN Special Interest Groups: Their Growth and Development Through the Years.

Over the past 25 years, the roles of school nurses have been both expanding and specializing in public and non-public school settings. To help meet the ever-changing and demanding challenges that specialized school nurses encounter in their unique settings, NASN embraced the idea that school nurses need a way to connect with colleagues working in similar practices. Thus, special interest groups (SIGs) were established, and the SIGs have become an integral part of NASN.

A neural correlate for common trait dissociation: Decreased EEG connectivity is related to dissociative absorption.

Objective: Dissociation refers to a disintegration between psychological elements; common manifestations are embodied in "absorption and imaginative involvement," a propensity for being immersed in a stimulus while oblivious to the environment, and acting without awareness. Trait dissociation was hypothesized to relate to lower EEG signal connectivity, but studies on healthy populations are scarce. The present study set out to examine whether dissociative absorption in a nonclinical sample would be associated with decreased intrahemispheric coherence.

Are resting state spectral power measures related to executive functions in healthy young adults?

Resting-state electroencephalogram (rsEEG) has been found to be associated with psychopathology, intelligence, problem solving, academic performance and is sometimes used as a supportive physiological indicator of enhancement in cognitive training interventions (e.g. neurofeedback, working memory training).

Cognitive Evaluation of Israeli Air Force Pilot Cadets.

Objective: In aviation psychology, there is a constant need for the cognitive evaluation of pilots as part of operational fitness and safety criteria.

Methods: A cross-sectional study with comparison between the performance of Israeli Air Force pilot cadets (N = 318) and U.S.

The contribution of personal and seniority variables to the presence of stress symptoms among Israeli UAV operators.

Background: The exposure to war scenes via screens, despite offering a degree of detachment, can be stressful for the operator. The aim of the current study is to examine the existence of anxiety, depression, and post traumatic stress disorder (PTSD) symptoms among unmanned aerial vehicle (UAV) Israeli operators.

Methods: Participants comprised 41 UAV operators (87.

Mechanisms of cognitive control in cadet pilots.

Background: Optimizing performance of aviators while minimizing risks arising from the exposure to extreme environment, both external and internal, is one of the principles guiding the Israeli Air Force. Young cadets in particular are considered an "at risk" population due to the fact that they have no experience in flight in the first stages of training and are therefore subjects for investigation.

Methods: In this study, we investigated the cognitive performance of young cadet pilots across different hours of the day.

Town & Gown.

Innovative approaches for building "town and gown" relationships between practicing school nurses, community partners, and universities/colleges are presented through exemplars relating to research, education, policy, and practice. The exemplars demonstrate the critical factors of successful partnerships as validated by their outcomes.

End of Life in a Haitian American, Faith-Based Community: Caring for Family and Communal Unity.

This article presents two models resulting from a grounded theory study of the end-of-life decision-making process for Haitian Americans. Successful access to this vulnerable population was achieved through the faith-based community. The first model describes this faith-based community of Haitian Americans.

Absorbed in sleep: Dissociative absorption as a predictor of sleepiness following sleep deprivation in two high-functioning samples.

In recent years, a labile sleep-wake cycle has been implicated as a cause for dissociative experiences, and studies show that dissociation is elevated following sleep deprivation. Dissociative individuals may find it harder to regulate sleepiness in the face of sleep disruption. Although there is significant variability in reactions to sleep deprivation, research on trait predictors is scarce.

Social Media Use by Transplant Recipients for Support and Healing.

Transplant recipients use a diverse support network that now includes transplant-related social media support groups. The purpose of this study is to explore the use of social media sites by transplant recipients as a potential source of support and healing and the usefulness of Internet postings as a source of rich qualitative data. A qualitative descriptive design was used for the study.

On Virtual Presence.

Advances in health care and communication technology have expanded nursing practice to nontraditional environments that preclude the physical presence of the nurse for a caring encounter. An increasing number of nurses are creating and maintaining nurse-patient relationships and practicing in a diverse range of specialties in virtual/distance environments. Can nursing presence as a caring modality be "real" in a virtual/distance environment? A new ontology of nursing presence is offered that transcends people, place, space, and time.

Influence of electroencephalography neurofeedback training on episodic memory: a randomized, sham-controlled, double-blind study.

The relationships between memory processes and oscillatory electroencephalography (EEG) are well established. Neurofeedback training (NFT) may cause participants to better regulate their brain EEG oscillations. The present study is a double-blind sham-controlled design investigating the effect of NFT on memory.

Clarifying a vision for health literacy: a holistic school-based community approach.

Health literacy has come to the forefront as an emerging health issue. Processes are needed to incorporate health literacy across community-wide settings. The purpose of this article is to describe the process used to assist community partners in a school health program in clarifying their vision of health literacy from which a more holistic approach to the care of school-aged children and the community was co-created.

Psychometric testing of the Gordon Facial Muscle Weakness Assessment Tool.

School nurses may be the first health professionals to assess the onset of facial paralysis/muscle weakness in school-age children. The purpose of this study was to test the psychometric properties of the Gordon Facial Muscle Weakness Assessment Tool (GFMWT) developed by Gordon. Data were collected in two phases.

Delegation guided by school nursing values: comprehensive knowledge, trust, and empowerment.

As health care institutions in the United States respond to shrinking budgets and nursing shortages by increasing the use of unlicensed assistive personnel (UAP), school nursing practice is changing from providing direct care to supervising activities delegated to UAP. Therefore, delegation is a critical area of concern for school nurses. The purpose of this qualitative research study was to explore values guiding the delegation of health care tasks to UAP in school settings from the perspective of the school nurse.

Bell's palsy in children: role of the school nurse in early recognition and referral.

Bell's palsy is the most common condition affecting facial nerves. It is an acute, rapidly progressing, idiopathic, unilateral facial paralysis that is generally self-limiting and non-life threatening that occurs in all age groups (Okuwobi, Omole, & Griffith, 2003). The school nurse may be the first person to assess facial palsy and muscle weakness in children.
