Purpose: Breast density is an important risk factor for breast cancer and varies substantially across racial-ethnic groups. However, determinants of breast density in Vietnamese immigrants in the United States (US) have not been studied. We investigated whether reproductive factors, immigration history, and other demographic and lifestyle factors were associated with breast density in Vietnamese Americans.Methods: We collected information on demographics, immigration history, and other lifestyle factors and mammogram reports from a convenience sample of 380 Vietnamese American women in California aged 40 to 70 years. Breast Imaging Reporting and Data System (BI-RADS) breast density was abstracted from mammogram reports. Multivariable logistic regression was used to investigate the association between lifestyle factors and having dense breasts (BI-RADS 3 or 4).Results: All participants were born in Viet Nam and 82% had lived in the US for 10 years or longer. Younger age, lower body mass index, nulliparity/lower number of deliveries, and longer US residence (or younger age at migration) were associated with having dense breasts. Compared to women who migrated at age 40 or later, the odds ratios and 95% confidence intervals for having dense breasts among women who migrated between the ages of 30 and 39 and before age 30 were 1.72 (0.96-3.07) and 2.48 (1.43-4.32), respectively.Conclusions: Longer US residence and younger age at migration were associated with greater breast density in Vietnamese American women. Identifying modifiable mediating factors to reduce lifestyle changes that adversely impact breast density in this traditionally low-risk population for breast cancer is warranted.

Background: To address the shortage of Doctor of Philosophy (PhD)-prepared nursing faculty, universities in the United States offer direct-entry Bachelor of Science in Nursing (BSN)-to-PhD nursing programs. Little research has been conducted to explore students' perceptions of these programs and to formally evaluate the successes and opportunities for growth of this academic track. Method: Focusing on the perceptions and experiential reflection of BSN-to-PhD education, a survey with open-ended questions was distributed among voluntary participants who are current BSN-to-PhD students or recent graduates (within 5 years) from various universities in the United States. Textual data were analyzed using a qualitative descriptive approach with thematic analysis. Results: This article elaborates on opportunities, challenges, and suggestions related to this educational route, as recognized by 21 participants from seven universities. Conclusion: The study findings may facilitate discussion among nurse educators to revise programs to be congruent with the needs of current students while paving the way for future scholars.

Aims:Participation in family and recreational activities, self-care, and parent ease of caregiving are important outcomes for young children with cerebral palsy (CP). The aim of this study was to examine use of the Child Engagement in Daily Life and the Ease of Caregiving for Children to measure change over time.Methods:A convenience sample of 387 parents of young children with CP (18 months to 5 years of age) completed the measures twice, a mean of 12.7 months apart.Results:For the Child Engagement in Daily Life, parents of children in Gross Motor Function Classification System level I and levels II–III reported more change for the Self-care domain (medium effect) than the Family and Recreational Activities domain (small effect) and the Ease of Caregiving for Children (small effect). The change reported by parents of children in levels IV–V on all three measures was less than the criterion for a small effect. Minimal detectable change for each measure varied from 12.1 to 14.1, out of a total possible score of 100.Conclusion:Further research is recommended to determine responsiveness to change following intervention.

We investigated the effects of increasing salinity and inundation on inorganic N exchange and P sorption/precipitation in soils of tidal freshwater floodplain forests (TFFF) of coastal Georgia, USA. Our objectives were to better understand how sea level rise, increasing inundation, and saltwater intrusion will affect the ability of TFFFs to retain nitrogen (N) and phosphorus (P). We collected soil cores (0-5 cm) from three TFFFs that do not currently experience saltwater intrusion and from one TFFF currently experiencing saltwater intrusion and measured NH-N exchange and PO-P removal over five simulated 6-h tidal cycles using nutrient-enriched freshwater (30 μM NH-N and 5 μM PO-P). In a second experiment, we exposed soil cores to three salinities (0, 2, and 5) and two inundation depths (5 and 10 cm) using the same nutrient enrichment. When flooded with nutrient-enriched freshwater, soils from the three TFFFs that do not experience saltwater intrusion removed inorganic N and P in amounts ranging from 5.2 to 10.7 and 2.3 to 4.4 mg/m, respectively, and the TFFF soils experiencing saltwater intrusion removed 2.1 to 3.8 mg P/m. However, TFFF soils experiencing saltwater intrusion released inorganic N to the water column in amounts ranging from 7.1 to 67.5 mg/m. In the second experiment, soils from TFFFs not experiencing saltwater intrusion released NH-N to the water column when exposed to 2 and 5 salinity, and the amount of N released increased with salinity and number of tidal cycles. In contrast, the same TFFF soils sorbed two and three times more PO-P when exposed to 2 and 5 salinity than when exposed to 0 salinity. P removal on a mass basis was greater under 10 cm of inundation, but the efficiency of removal was greater under the 5 cm flooding depth. Our findings suggest that saltwater intrusion caused by sea level rise will promote N release into the water column through organic matter mineralization and/or ion exchange and may promote P sorption, or precipitation of P with metal cations. In addition, release of N and resulting increased N/P could exacerbate eutrophication of estuaries in the future. [ABSTRACT FROM AUTHOR]

The number of Korean people who are currently suffering from depressive disorders that require medical treatment is assumed to be more than 2 million. However, only around 15% of those with depressive disorder are actively receiving medical treatment, and this leads to an increasing suicide rate. Hence, the National Evidence-based Healthcare Collaborating Agency held a round-table conference to provide information on depression and suicide and suggested a reasonable policy through comprehensive discussion with experts. The prevalence of depression, which is closely related to suicide rates, is lower in Korea than in the U.S., but the rate of suicide is the highest among Organisation for Economic Co-operation and Development countries. It is thought that the underestimated prevalence of depression is owing to the inconsistency between the diagnostic criteria of depression and characteristics of depression in Korea. Therefore, it is necessary to develop Korean diagnostic criteria for depression reflecting cultural characteristics and conduct a regular and organized nationwide survey. Moreover, a term related to suicide officially used by Statistics Korea is 'intentional self-injury'. However, in a Korea-based community study, it was found that 60% to 72% of those attempting suicide had mental disorders; thus suicide is not merely an intentional self-injury but a medical condition that should be treated. To reduce suicide, both medical and social approaches are necessary. Furthermore, a strengthening of the public perception that a medical approach is important for suicide prevention is greatly needed. Moreover, it is necessary to prepare an effective national suicide prevention strategy through studies evaluating the suicide prevention policies currently implemented and psychological autopsy of suicide deaths similar to those practiced in Finland.
