Samuel Merritt University, formerly Samuel Merritt College, was founded in 1909 as a hospital school of nursing. It is a fully accredited health science institution located on the Summit campus of the Alta Bates Summit Medical Center in Oakland, California, United States. Samuel Merritt offers undergraduate degrees in nursing and graduate degrees in nursing, physical therapy, physician assistant, occupational therapy, and podiatric medicine. The baccalaureate nursing program is offered cooperatively with Saint Mary's College of California in Moraga, Mills College, Holy Names University and Notre Dame de Namur University. Samuel Merritt University is an affiliate of the Sutter Health Network and Alta Bates Summit Medical Center.Samuel Merritt is the only provider of physical and occupational therapists and physician assistants and is the largest source of nurses in the greater East Bay.

Introduction: Hyperglycemia associated with diabetes mellitus (DM) has adverse impacts on peripheral nerve connective tissue structure, and there is preliminary evidence that nerve biomechanics may be altered. Methods: Ultrasound imaging was utilized to quantify the magnitude and timing of tibial nerve excursion during ankle dorsiflexion in patients with DM and matched healthy controls. Results: Tibial nerve longitudinal excursion at the ankle and knee was reduced, and timing was delayed at the ankle in the DM group. Severity of neuropathy was correlated with larger reductions in longitudinal excursion. Nerve cross-sectional area was increased at the ankle in the DM group. Conclusions: Larger tibial nerve size within the tarsal tunnel in patients with DM may restrict longitudinal excursion, which was most evident with more severe neuropathy. It is hypothesized that these alterations may be related to painful symptoms during functional activities that utilize similar physiological motions through various biomechanical and physiological mechanisms. © 2014 Wiley Periodicals, Inc.

Peripheral nerves are composed of motor and sensory axons, associated ensheathing Schwann cells, and organized layers of connective tissues that are in continuity with the tissues of the central nervous system. Nerve fiber anatomy facilitates conduction of electrical impulses to convey information over a distance, and the length of these polarized cells necessitates regulated axonal transport of organelles and structural proteins for normal cell function. Nerve connective tissues serve a protective function as the limb is subjected to the stresses of myriad limb positions and postures. Thus, the tissues are uniquely arranged to control the local nerve fiber environment and modulate physical stresses. In this brief review, we describe the microscopic anatomy and physiology of peripheral nerve and the biomechanical properties that enable nerve to withstand the physical stresses of everyday life. © 2012 Hanley & Belfus, an imprint of Elsevier Inc.

Grief is a normal response after pregnancy loss. Potentially, prolonged periods of grief can have a negative impact on physical or mental health. African-American women experience pregnancy loss at rates that are at least twice the rate of any other racial or ethnic group. However, the research literature on pregnancy loss has failed to include representative samples of African-American women or to explore and describe adequately their unique experiences after pregnancy loss. The purpose of this study was to examine the factors that are related to grief intensity after pregnancy loss (i.e., miscarriage, ectopic pregnancy, or fetal death) among African-American women. The results presented in this paper are components of a larger study in which the grief and coping experiences of African-American women following pregnancy loss were examined, using both quantitative and qualitative analysis. Eighty-six (N = 86) African-American women with a self-reported history ofinvoluntary pregnancy loss were recruited using a variety of culturally sensitive methods. The women completed three instruments: the Perinatal Grief Scale-Short Form (PGS-S), the Women's Role Integration Protocol (WRIP), and a personal profile tool designed specifically for the study. Pearson correlations were computed using pairwise deletion. Four models were tested using hierarchical multiple regression. Age and level of role integration were recurring predictors of the various dimensions of grief as measured by the PGS-S. Being older and reporting more major role satisfaction contributed to having less grief intensity after pregnancy loss. It is proposed that women with a history of pregnancy loss be assessed for residual grieving across their life span. Future explorations should address two main areas: specific interpersonal relations that facilitate grief management and the partners' experiences after pregnancy loss.

Since the birth of the first IVF-conceived child in 1978, the use of assisted reproductive technologies (ART) has grown dramatically, contributing to the successful birth of 5 million individuals worldwide. However, there are several reported associations of ART with pregnancy complications, such as low birthweight (LBW), preterm birth, birth defects, epigenetic disorders, cancer and poor metabolic health. Whether this is attributed to ART procedures or to the subset of the population seeking ART remains a controversy, but the most relevant question today concerns the potential long-term implications of assisted conception. Recent evidence has emerged suggesting that ART-conceived children have distinct metabolic profiles that may predispose to cardiovascular pathologies in adulthood. Because the eldest IVF individuals are still too young to exhibit components of chronic middle-aged syndromes, the use of animal models has become particularly useful in describing the effects of unusual or stressful preimplantation experiences on adult fitness. Elucidating the molecular mechanisms by which embryos integrate environmental signals into development and metabolic gene expression programs will be essential for optimizing ART procedures such as in vitro culture conditions, embryo selection and transfer. In the future, additional animal studies to identify mechanisms underlying unfavorable ART outcomes, as well as more epidemiological reviews to monitor the long-term health of ART children are required, given that ART procedures have become routine medical practice. © The Author 2012.

Background: The straight leg raise (SLR) neurodynamic test is commonly used to examine the sensitivity of the lower quarter nervous system to movement. Range of motion during the SLR varies considerably, due to factors such as age, sex and activity level. Knowing intra-individual, inter-limb differences may provide a normative measure that is not influenced by such demographic characteristics. This study aimed to determine normal asymmetries between limbs in healthy, asymptomatic individuals during SLR testing and the relationship of various demographic characteristics. Methods. The limb elevation angle was measured using an inclinometer during SLR neurodynamic testing that involved pre-positioning the ankle in plantar flexion (PF/SLR) and neutral dorsiflexion (DF/SLR). Phase 1 of the study included 20 participants where the ankle was positioned using an ankle brace replicating research testing conditions. Phase 2 included 20 additional participants where the ankle was manually positioned to replicate clinical testing conditions. Results: The group average range of motion during PF/SLR was 57.1 degrees (SD: 16.8 degrees) on the left and 56.7 degrees (SD: 17.2 degrees) on the right while during DF/SLR the group average was 48.5 degrees (SD: 16.1 degrees) on the left and 48.9 degrees (SD: 16.4 degrees) on the right. The range of motion during SLR was moderately correlated to weight (-0.40 to -0.52), body mass index (-0.41 to -0.52), sex (0.40 to 0.42) and self-reported activity level (0.50 to 0.57). Intra-individual differences between limbs for range of motion during PF/SLR averaged 5.0 degrees (SD: 3.5 degrees) (95% CI: 3.8 degrees, 6.1 degrees) and during DF/SLR averaged 4.1 degrees (SD: 3.2 degrees) (95% CI: 3.1 degrees, 5.1 degrees) but were not correlated with any demographic characteristic. There were no significant differences between Phase 1 and Phase 2. Conclusions: Overall range of motion during SLR was related to sex, weight, BMI and activity level, which is likely reflected in the high variability documented. We can be 95% confident that inter-limb differences during SLR neurodynamic testing fall below 11 degrees in 90% of the general population of healthy individuals. In addition, inter-limb differences were not affected by demographic factors and thus may be a more valuable comparison for test interpretation. © 2012 Boyd and Villa; licensee BioMed Central Ltd.
