Blastocyst development after sperm selection at high magnification is associated with size and number of nuclear vacuoles

Spermatozoa selection at high magnification before intracytoplasmic sperm injection seems to be positively associated with pregnancy rates after day 3 embryo transfers. The aim was to demonstrate an association between the presence of vacuoles in sperm nuclei and the competence of embryos to develop to day 5. Grading of spermatozoa at x 6000-x 12,500 magnification: grade I, no vacuoles; grade II, or=1 large vacuole; grade IV, large vacuoles with other abnormalities. The outcome of embryo development in a group of 25 patients after sibling oocyte injection with the four different grades of spermatozoa showed no significant difference in embryo quality up to day 3. However, the occurrence of blastocyst formation was 56.3 and 61.4% with grade I and II spermatozoa respectively, compared with 5.1% with grade III and 0% with grade IV respectively (P < 0.001). Spermatozoa selection at high magnification using Nomarski interference contrast is useful to identify more precisely the size and the number of nuclear vacuoles that greatly exert a negative effect on embryo development to the blastocyst stage. These observations confirm previous studies pointing to possible 'early and late paternal effects', both of which may have an impact on early embryonic development.     

Vitamin D Status among Women in a Rural District of Nepal: Determinants and Association with Metabolic Profile—A Population-Based Study

Hypovitaminosis D is prevalent worldwide, and especially in South-Asia. According to the Institute of Medicine (IOM), 25(OH)D levels below 30 nmol/L are defined as vitamin D deficiency (VDD) and levels between 30–50 nmol/L as insufficiency (VDI). Besides its role in calcium homeostasis, it has been postulated that vitamin D is involved in metabolic syndrome. Given the scarcity of data on vitamin D status in Nepal, we aimed to examine the prevalence of VDD and VDI, as well as the determinants and association with metabolic parameters (lipids, HbA1c), in a cohort of women in rural Nepal. Altogether, 733 women 48.5 ± 11.7 years of age were included. VDD and VDI were observed in 6.3 and 42.4% of the participants, respectively, and the prevalence increased by age. Women reporting intake of milk and eggs > 2 times weekly had higher 25(OH)D levels than those reporting intake < 2 times weekly. Women with vitamin D levels < 50 nmol/L displayed higher levels of cholesterol, LDL-cholesterol, triglycerides, and HbA1c. Additionally, a regression analysis showed a significant association between hypovitaminosis D, dyslipidemia, and HbA1c elevation. In conclusion, VDI was prevalent and increased with age. Milk and egg intake > 2 times weekly seemed to decrease the risk of VDI. Moreover, hypovitaminosis D was associated with an adverse metabolic profile.     

Balancing Within Various Discourses—The Art of Being Old and Living as a Sami Woman

The aim of this part of the Umeå 85+ Study was to explore how indigenous women narrate their lives and their experience of being old as Sami women. Interviews with 9 old Sami women were analyzed using grounded theory. The categories identified were “reindeer as the basis of life,” “longing for significant Sami values,” “feeling valued as a Sami woman,” and “changing for survival;” these evolved into the core category: “balancing within various discourses—the art of being old and living as a Sami woman.” Knowing how to balance provided the ability to make use of available opportunities.     

Prevention of colorectal cancer by colonoscopic surveillance in families with hereditary colorectal cancer

Objective. In recent years persons at risk for colorectal cancers (CRC) have been subjected to follow-up with colonoscopy in many centres. There is, however, limited knowledge about the effect of such interventions. The objective of this study was to report the results of our observations during the past 15 years. Material and methods. Healthy persons were included in the study according to their family history of CRCs, and prospectively followed with colonoscopies. Results. Altogether, 1133 individuals were included and observed for a total of 3474 follow-up years from the first to the last colonoscopy initiated by our activity. Mismatch repair (MMR) mutations were detected in 6.5% of cases. A total of 1383 polyps were removed, 72% were less than 5 mm in diameter. Findings were scored as hyperplastic polyps (n=887), adenomas with mild to moderate dysplasia (n=460), adenomas with high-grade dysplasia (n=30) and cancers (n=6). Two cancers were observed after the first colonoscopy, compared with 2.6 expected by chance and more than 20 expected under the hypothesis of predominant inherited diseases in the families. Observed annual incidence rates for adenomas were similar in all groups, while in the mutation carriers there was a higher frequency of progression to severe dysplasia or infiltrating cancer. Conclusions. A simple explanation for the combined findings may be that all selected families had a similar tendency to produce adenomas, while mutation carriers more frequently demonstrated dysplasia/cancer in the adenomas. The low annual incidence rates for CRC indicated that the removal of adenomas may have prevented cancers.     

Revolutionizing Child Welfare with Outcomes Management

Outcomes management technology holds great promise for improving the quality of services provided to youth in the child welfare system. Advantages include better detection of behavioral health and trauma-related issues, early indicators of case progress or risk of failure, and program- and system-level learning. Yet organizational barriers to implementation persist. Attention is spent in this paper on addressing these barriers so the use of outcomes management technology becomes a common practice. A model for predicting resiliency is presented, along with case examples demonstrating its potential use for treatment planning and monitoring progress.     

Topical Versus Injectable Analgesics in Simple Laceration Repair: An Integrative Review

Simple lacerations that need suture repair are a common occurrence encountered by nurse practitioners in practice. Clinicians often wonder which form of analgesia is best when repairing a minor skin laceration. Pain management during the procedure is often undertreated, allowing negative patient consequences to arise. This integrative review examines what is known about the differences of topical versus local injection of analgesia products. The review also examines the advantages and disadvantages of each application and highlights findings for nurse practitioners to make evidence-based decisions regarding laceration repair.
