Defensive burying: Effects of diazepam and oxprenolol measured in extinction

When a rat is shocked via a prod in a chamber with sawdust on the floor it will typically push the flooring material with snout and forepaws towards and over the prod. We administered diazepam (.5 and 1.0 mg/kg) and oxprenolol (10 and 20 mg/kg) the day following shock exposure, and observed the complete suppression of burying by diazepam, and some suppression with oxprenolol. These effects are independent of interference with initial association of shock and prod, and of changes in general activity.

Parental support in neonatal intensive care units: a cross-cultural comparison between New Zealand and Japan.

This is a cross-cultural comparative study involving both quantitative and qualitative data analyses. This study examines sources of parental stress in the two neonatal intensive care units (NICUs) located in New Zealand and Japan and explores how cultural norms of NICU care environments influence parental stress-related experiences and nursing support. The three main sources of data collection were the following: a NICU staff interview, parental interview, and parental questionnaire survey, the PSS: NICU. Thirty-one pairs of parents in each NICU (N = 121) participated in this study. The differences between the two NICUs in terms of the NICU care environment and sources of parental stress within the NICU contexts were identified, highlighting NICU characteristics associated with the sources of stress in the two NICUs. Recognition of the norms of NICU care environments that may hinder parent-staff communication is an important element of NICU nursing practice.

Building resiliency: a cross-sectional study examining relationships among health-related quality of life, well-being, and disaster preparedness

BackgroundWorldwide, disaster exposure and consequences are rising. Disaster risk in New Zealand is amplified by island geography, isolation, and ubiquitous natural hazards. Wellington, the capital city, has vital needs for evacuation preparedness and resilience to the devastating impacts and increasing uncertainties of earthquake and tsunami disasters. While poor quality of life (QoL) is widely-associated with low levels of engagement in many health-protective behaviors, the relationships among health-related quality of life (HrQoL), well-being, and preparedness are virtually unknown.MethodsWe hypothesized that QoL and well-being affect household evacuation preparedness. We performed a quantitative epidemiologic survey (cross-sectional design) of Wellington adults. Our investigation assessed health-promoting attributes that build resiliency, conceptualized as health-protective attitudes and behaviors. Multidimensional QoL variables were measured using validated psychometric scales and analyzed for associations with evacuation preparedness, and we determined whether age and gender affected these relationships.ResultsWe received 695 survey responses (28.5% response rate; margin of error ±3.8%; 80% statistical power to detect true correlations of 0.11 or greater). Correlational analyses showed statistically significant positive associations with evacuation preparedness for spiritual well-being, emotional well-being, and life satisfaction. No associations were found for mental health, social well-being, or gender; physical health was weakly negatively associated. Evacuation preparedness increased with age. Regression analyses showed that overall health and well-being explained 4.6-6.8% of the variance in evacuation preparedness. Spiritual well-being was the only QoL variable that significantly and uniquely explained variance in preparedness.ConclusionsHow well-being influences preparedness is complex and deeply personal. The data indicate that multidimensional readiness is essential, and meaningfulness is an important factor. Inadequate levels of tangible preparedness actions are accompanied by gaps in intangible readiness aspects, such as: 1) errors in perceived exposure to and salience of natural hazards, yielding circumscribed risk assessments; 2) unfamiliarity with the scope and span of preparedness; 3) underestimating disaster consequences; and 4) misinterpreting the personal resources required for self-managing disaster and uncertainty. Our results highlight that conceptualizing preparedness to include attitudes and behaviors of readiness, integrating well-being and meaningfulness into preparedness strategies, and prioritizing evacuation planning are critical for resiliency as a dynamic process and outcome.

Bridging Indigenous and Western Sciences: Research Methodologies for Traditional, Complementary, and Alternative Medicine Systems

Emergent research methodologies congruent with Indigenous knowledge and worldviews are providing access to insights from traditional, complementary, and alternative medicine, including Indigenous healing systems. Tension is evident for researchers balancing representation of Indigenous realities with expectation to conform to the conventionality and rationality of “acceptable” Western science–based research protocols. Where past research pursuits have been limited by polarized views of legitimacy and validity, Western science and Indigenous science are now converging as equally valid notions of science to guide emergent research practices such as Kaupapa Māori. This narrative synthesis explores complex relations between epistemology, methodology, and practice. It aims to contribute to the transfer of knowledge between Indigenous and Western scientific paradigms.

Transituational Immunization Against the Interference Effect (Learned Helplessness) by Prior Passive and Active Escape

Rats were taught to escape shock by either a relatively active jump-up response or by a relatively passive crouching-freezing response. One half of each group then received inescapable tail shocks in a restraining tube while the other half were restrained without shock. Control groups received either inescapable shock or restraint without prior escape training. An additional control group remained in its home cage throughout these procedures. All rats were then taught to escape shock in a shuttlebox by completing two crossings per trial (fixed ratio two) for 25 trials. Compared with the untreated controls, the group receiving inescapable shock alone showed learned helplessness. Both passive and active escape training immunized against learned helplessness, with passive escape training being the most effective. Restraint alone also produced some interference with shuttle escape, unaffected by immunization pretreatments. Activity measures during inescapable shock showed that passive escape trained rats were most active, while active escape trained and control rats showed the same lower level of activity.

Prepared for what? Addressing the disaster readiness gap beyond preparedness for survival

BackgroundConventional disaster preparedness messaging focuses largely on promoting survival actions and communications planning for the immediate post-disaster period. While such preparedness is vital, we have long-observed a gap in preventive medicine and disaster planning for building personal resilience – preventatively – to persevere through prolonged recovery timeframes. There are many helpful attitudes and behaviors that people can develop to increase their readiness and capacity for drastic life changes, encompassing not only health-protective preparedness actions but health-promoting attitudes for “minding the risk” and “practicing resilience” as well. For instance, quality of life assessments and well-being interventions are widely-known for the clinically significant improvements they can produce in patient-reported outcomes. Similarly, health promotion interventions are implemented preventatively when a risk is identified yet a disease is not present, and can provide health benefits throughout people’s lives, regardless of the type of adversities they eventually encounter (medical, environmental, or other).DiscussionWe argue there is an overlooked opportunity to leverage well-being theories and methods from clinical settings and public health practice for the purpose of preventatively boosting disaster readiness and bolstering capacity for long-term resilience. We also highlight our previously-published research indicating a role for integrating personal meaning into preparedness messages. This is an opportune time for applying well-being concepts and practices as tools for developing disaster readiness, as risk awareness grows through real-time tracking of hazardous events via social media. For example, two sudden-onset disasters occurred within ten days of each other in 2014 and caught worldwide attention for their extreme hazards, despite dramatic differences in scale. The 22 March 2014 landslide tragedy in Washington State, USA, and the 1 April 2014 Chilean earthquake and Pacific-wide tsunami alerts brought home how persistently vulnerable we all are, and how developing intrinsic personal readiness for scientifically-known risks before disaster unfolds is essential policy.SummaryGap programming that addresses personal readiness challenges in prevention timeframes could save lives and costs. We contend that bridging this readiness gap will prevent situations where people, communities, and systems survive the initial impact, but their resilience trajectories are vulnerable to the challenges of long-haul recovery.

Research methodology: choices, logistics, and challenges.

Many complex issues are central to the ongoing debate about health care and health care delivery system reform in the United States (US) and worldwide. Academic medical centers, vulnerable populations, rural health, and hospitals represent but a few aspects of the fragmentation of the current health care delivery system. Although research offers considerable potential for generating insights into these issues, the challenge of developing and applying effective research methodology to study integrated health care delivery systems raises complex issues. In recent years, the roles, benefits, and challenges to appropriate use of research methods in the basic and applied social and clinical sciences have been debated extensively. These debates continue today.

Epidemiology of dental caries among adolescents in Tamil Nadu, India

OBJECTIVE Economic and dietary changes in the Indian state of Tamil Nadu have led to compromised oral health status of the adolescent population. Adequate epidemiological data are not available to address the prevention or treatment needs in this region of India. The aim of this study was to measure the prevalence and severity of dental caries among adolescents of Tamil Nadu, a southern state of India. METHODS The study sample included 974 adolescent school students (12-15 years of age) from both rural and urban areas of Tamil Nadu, India. The decayed, missing and filled teeth (DMFT) index of these students was measured using the World Health Organization oral health survey method, in a quantitative cross-sectional study. RESULTS The oral health survey indicated that the prevalence of dental caries among adolescents in rural and urban areas of Tamil Nadu was 61.4%, with an average DMFT score of 2.03. Multiple regression analyses indicated factors such as gender, mothers education, type of school and caste as significant predictors of dental caries. CONCLUSION Female gender, Scheduled Caste and Tribes attending public schools in rural areas were identified as the more vulnerable populations to be affected by dental caries. Oral health policies should be targeted to these adolescent populations in the Tamil Nadu region.

Applying Community-Based Participatory Research to Create a Diabetes Prevention Documentary with New Zealand Māori

Background: Type 2 diabetes is almost three times more prevalent in the indigenous people of New Zealand (Māori) than non-Māori. Despite the high rate of diabetes in the Māori population, little is known about their personal understanding or experience of the disease. Objectives: To engage Māori in a participatory process to develop a culturally relevant diabetes prevention documentary. Methods: Principles of community-based participatory research (CBPR) were applied to a qualitative research design employing key informant interviews and focus groups to develop a diabetes prevention documentary. Conclusions: A CBPR approach provides an appropriate model for enacting local action-oriented approaches in the creation of a documentary that reflects Māori cultural beliefs and practices.

Effects of inhaled corticosteroids on voice production in healthy adults

Abstract The isolated effects of inhaled corticosteroids (ICS) on voice production were examined in 30 healthy adults with no known pre-existing airway disease. All participants followed a daily ICS treatment regime of 500 μg in the morning and evening over a 6-day period. Sustained vowels and connected speech samples were audio recorded before, during, and after the ICS regime. Each participants audio recorded samples were acoustically analysed. Results revealed that ICS has a short-term detrimental effect on various acoustic properties of voice. These effects were more evident in connected speech compared to isolated vowel productions. All acoustic parameters returned to normalcy after discontinuing the ICS. The study provides insight as to the influence of ICS on healthy voice production.
