Good for Baby, Good for Mom: The Determinants of Breastfeeding Initiation and Continuation Among Working Women in the Midwest U.S.

Various factors support or hinder women’s decision to initiate and continue breastfeeding, particularly among working women. Currently, limited literature investigates breastfeeding experiences among working women across time. The purpose of this study was to gain nuanced insight into working women’s breastfeeding experiences during the first year of their infant’s life. Semi-structured, in-depth interviews were conducted with working women residing in a Midwestern state (N = 25) across two time points (when infants were 3-4 months and 9-12 months). Results showed that twenty-one working women initiated and continued breastfeeding when their infants were 3-4 months old, and 14 women in the sample continued breastfeeding when their infants were 9-12 months old. Five themes emerged regarding barriers and facilitators of breastfeeding initiation and continuation. Individual-level factors included 1) Women’s perceptions of breastfeeding as nurturing and pleasurable as well as frustrating and painful and 2) Maternal self-efficacy and beliefs. Setting-level themes included: 3) Active and passive workplace supports, 4) Lactation and breastfeeding supports in the community, and 5) Childcare provider supports. Findings suggest the importance of resources, programming and policy efforts that support the expansion of statewide breastfeeding programs, breastfeeding education for health professionals and childcare providers, lactation rooms, and flexible work scheduling

Assessing the performance and efficiency of environmental DNA/RNA capture methodologies under controlled experimental conditions

Growing interest and affordability of environmental DNA and RNA (eDNA and eRNA) approaches for biodiversity assessments and monitoring of complex ecosystems have led to the emergence of manifold protocols for nucleic acids (NAs) isolation and processing. Although there is no consensus on a standardized workflow, the common practice for water samples is to concentrate NAs via filtration using varying pore size membranes. Using the smallest pore is assumed to be most efficient for NAs capture from a wide range of material (including sub-cellular particles); however, a trade-off must occur between detection of a meaningful molecular signal and cost/time effort when processing samples using fine pore membranes. Comparative studies involving formal efficiency assessments are lacking, which restricts informed decision-making around an optimized sampling approach for applications such as biosurveillance (i.e. detection and monitoring of target taxa—nuisance organisms, endangered and indicator taxa or other species of economic or cultural importance). Here, we present an experimental study using an easily cultured microalgal species (Alexandrium pacificum) to test different filter membranes for capturing NAs in the context of cost/time effort and cell fractions encountered in nature (whole cells, partially lysed and naked NAs). The results showed no statistically significant difference between membrane types for capturing target eDNA signal from intact and partially lysed cell treatments. In terms of time effort and volume processed, higher efficiency ratings were obtained with the larger pore size (5 μm) cellulose membranes. Positively charged nylon demonstrated enhanced capture of naked NAs, and especially eRNA signal, across treatments. Our findings support using coarse pore size filters for adequate capture of target NA signal (from both eDNA and eRNA) with less processing time. The framework presented here can provide a quick and robust feasibility check and comparative assessment of new and existing NA processing technologies, and allows sufficient control over multiple parameters, including physical–chemical water properties, temporal scales, and concentration and type of input material

Occupational Exposure to Pfiesteria Species in Estuarine Waters Is Not a Risk Factor for Illness

BACKGROUND: Exposure to the dinoflagellate Pfiesteria has, under certain circumstances, been associated with deficits in human learning and memory. However, uncertainties remain about the health risk of chronic, low-level exposures (as seen among occupationally exposed commercial fishermen), particularly in light of studies suggesting that Pfiesteria strains are widespread in the estuarine environment in the U.S. mid-Atlantic region. METHODS: We selected an initial cohort of 152 persons, including 123 persons with regular, occupational exposure to the Chesapeake Bay; 107 of the cohort members were followed for the full four summer “seasons” of the study. Cohort members were questioned biweekly about symptoms, and data were collected about the areas of the bay in which they worked. These latter data were matched with data on the presence or absence of Pfiesteria in each area, based on polymerase chain reaction analysis of > 3,500 water samples. Cohort members underwent neuropsychological testing at the beginning and end of each summer season. RESULTS: No correlation was found between work in an area where Pfiesteria was identified and specific symptomatology or changes on neuropsychological tests. CONCLUSIONS: Although high-level or outbreak-associated exposure to Pfiesteria species (or specific strains within a species) may have an effect on health, routine occupational exposure to estuarine environments in which these organisms are present does not appear to pose a significant health risk

The definitive version was published in Harmful Algae 78 (2018): 129-141, doi:10.1016/j.hal.2018.08.006.Monterey Bay, California experiences near-annual blooms of Pseudo-nitzschia that can affect marine animal health and the economy, including impacts to tourism and commercial/recreational fisheries. One species in particular, P. australis, has been implicated in the most toxic of events, however other species within the genus can contribute to widespread variability in community structure and associated toxicity across years. Current monitoring methods are limited in their spatial coverage as well as their ability to capture the full suite of species present, thereby hindering understanding of HAB events and limiting predictive accuracy. An integrated deployment of multiple in situ platforms, some with autonomous adaptive sampling capabilities, occurred during two divergent bloom years in the bay, and uncovered detailed aspects of population and toxicity dynamics. A bloom in 2013 was characterized by spatial differences in Pseudo39 nitzschia populations, with the low-toxin producer P. fraudulenta dominating the inshore community and toxic P. australis dominating the offshore community. An exceptionally toxic bloom in 2015 developed as a diverse Pseudo-nitzschia community abruptly transitioned into a bloom of highly toxic P. australis within the time frame of a week. Increases in cell density and proliferation coincided with strong upwelling of nutrients. High toxicity was driven by silicate limitation of the dense bloom. This temporal shift in species composition mirrored the shift observed further north in the California Current System off Oregon and Washington. The broad scope of sampling and unique platform capabilities employed during these studies revealed important patterns in bloom formation and persistence for Pseudo-nitzschia. Results underscore the benefit of expanded biological observing capabilities and targeted sampling methods to capture more comprehensive spatial and temporal scales for studying and predicting future events.This work was supported by the National Oceanic and Atmospheric Administration (NA11NOS4780055, NA11NOS4780056, NA11NOS4780030) and a fellowship to H.

The Science Performance of JWST as Characterized in Commissioning

This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performance of the spacecraft, telescope, science instruments, and ground system, with an emphasis on differences from pre-launch expectations. Commissioning has made clear that JWST is fully capable of achieving the discoveries for which it was built. Moreover, almost across the board, the science performance of JWST is better than expected; in most cases, JWST will go deeper faster than expected. The telescope and instrument suite have demonstrated the sensitivity, stability, image quality, and spectral range that are necessary to transform our understanding of the cosmos through observations spanning from near-earth asteroids to the most distant galaxies.Comment: 5th version as accepted to PASP; 31 pages, 18 figures; https://iopscience.iop.org/article/10.1088/1538-3873/acb29

Finding Strength in Vulnerability: Ethical Approaches when Conducting Research with Vulnerable Populations

Researchers who desire to make positive changes for vulnerable populations often conduct problem-focused studies. Although problem focused research is important, when such studies are not carefully designed, their results can contribute to a deficit discourse. A deficit discourse is a narrative that describes the person through a myopic lens of negativity characterized only by illness, death, depression, failure, or the like. Deficit discourse negatively affects how health care providers and society interact with vulnerable people. This article discusses deficit discourse in health care and strengths-based research: an ethical approach to working with vulnerable individuals in research settings and a strategy to overcome deficit discourse. Strengths-based research approaches balance risks with countermeasures that include areas that are positive and amenable to growth or intervention. Strengths-based research can be conducted using qualitative, quantitative, or mixed-methods methodology. Strengths-based research should be culturally relevant and population-specific, often including the individuals of study throughout the process. By modifying the research approach, critical problems can be identified and addressed while also emphasizing positive ways to empower individuals and improve their lives. Additionally, these changes better the way researchers and health care providers view and care for people while also challenging deficit discourses in society at large

How to Create Videos for Extension Education: An Innovative Five-Step Procedure

Although the benefits of using video as a learning tool in Extension programs are well known, less is understood about effective methods for creating videos. We present a five-step procedure for developing educational videos that focus on evidence-based practices, and we provide practical examples from our use of the five steps in creating a video series for an Extension program. Through the effective development of videos, Extension professionals can organize and present information in a meaningful way. Using video media can be a successful way to demonstrate best practices, but there has been limited guidance for how to develop such media. The five-step procedure described in this article can be adapted in a variety of Extension areas to develop educational videos that effectively illustrate evidence-based practices

Informal Caregivers’ Well-Being at the Transition to Caregiving

The aim of this study was to describe the psychological and physical health needs of informal caregivers in a rehabilitation hospital and explore differences related to informal caregiver and care recipient characteristics. Readiness to engage in health promotion and perspectives on mindfulness meditation were assessed. Informal caregivers (N = 33) to patients receiving inpatient or outpatient treatment completed the Multidimensional Health Profile screening tools. Readiness to change was assessed using the readiness ruler approach. Almost half of participants (45.5%) had a chronic illness and 18.2% reported that it interferes with daily functioning. Low Positive Health Habits were reported by 43% of participants, and Negative Health Habits were reported by 25%. A subgroup (15%–20%) reported both physical and mental health concerns. A majority of participants indicated it was both very important for them to improve their physical and mental health and felt very confident they could do so. Receptivity to mindfulness meditation was high, with 72.7% reporting an interest. Comprehensive screening and counseling interventions to address the physical and mental health of informal caregivers in physical rehabilitation hospital settings are needed, and information gained from screening could be addressed in interventions delivered by systems-oriented rehabilitation counselors. A mindfulness meditation intervention may be a useful strategy for promoting well-being in this population
