A compact cold-atom interferometer with a high data-rate grating magneto-optical trap and a photonic-integrated-circuit-compatible laser system.

The extreme miniaturization of a cold-atom interferometer accelerometer requires the development of novel technologies and architectures for the interferometer subsystems. Here, we describe several component technologies and a laser system architecture to enable a path to such miniaturization. We developed a custom, compact titanium vacuum package containing a microfabricated grating chip for a tetrahedral grating magneto-optical trap (GMOT) using a single cooling beam. In addition, we designed a multi-channel photonic-integrated-circuit-compatible laser system implemented with a single seed laser and single sideband modulators in a time-multiplexed manner, reducing the number of optical channels connected to the sensor head. In a compact sensor head containing the vacuum package, sub-Doppler cooling in the GMOT produces 15 µK temperatures, and the GMOT can operate at a 20 Hz data rate. We validated the atomic coherence with Ramsey interferometry using microwave spectroscopy, then demonstrated a light-pulse atom interferometer in a gravimeter configuration for a 10 Hz measurement data rate and T = 0-4.5 ms interrogation time, resulting in Δg/g = 2.0 × 10-6. This work represents a significant step towards deployable cold-atom inertial sensors under large amplitude motional dynamics.

Adherence to Treatment by African Americans Undergoing Hemodialysis.

End stage renal disease (ESRD) affects African Americans more than any other ethnic group. Adherence is a challenge. Patients with ESRD must adhere to medication, diet, fluid restrictions, and dialysis treatment schedules if they do not receive a kidney transplant. The purpose of this exploratory, descriptive study was to assess adherence in 120 African Americans with ESRD undergoing hemodialysis (HD). Participants completed a demographic questionnaire and the ESRD Adherence Questionnaire (ESRD-AQ). Biomarkers were collected from medical records. Few participants (24%) adhered to dietary restrictions; however, fluid restriction was reported as the most difficult to manage, which was consistent with the interdialytic weight gain biomarker. Older participants were more adherent. Participants were adherent with HD attendance and medication. Participants reported frequent communication with the healthcare team, but a more formal process needs to be implemented with follow up to ensure understanding and reinforce adherence.

Minimal adverse effects profile following implantation of periauricular percutaneous electrical nerve field stimulators: a retrospective cohort study.

The periauricular percutaneous implantation of the Neuro-Stim System™ family of devices EAD, MFS, and BRIDGE is a procedure involving the use of a non-opiate, neuromodulation analgesic for relieving acute and chronic pain. It has been approved as a minimal-risk procedure by multiple governmental and institutional facilities. This retrospective report of findings will help quantify the incidence of clinically observed bleeding, localized dermatitis, and infections at the implantation sites of the electrode/needle arrays, dermatitis at the site of the generator, and patient syncope. A total of 1,207 devices, each producing up to 16 percutaneous punctures, for a total of 19,312 punctures were monitored for adverse effects, based on retrospective chart audits conducted at six clinical facilities over a 1-year period.

An Older Transgender Woman's Quest for Identity.

Despite sensationalized media attention, transgender individuals are the most marginalized and misunderstood group in the lesbian, gay, bisexual, and transgender (LGBT) community. The current article presents a case study of one woman's quest for identity. Narrative inquiry was used to analyze data from interview transcripts and four themes emerged during analysis: (a) naming the ambiguity, (b) revealing-concealing the authentic self, (c) discovering the transgender community, and (d) embracing the "T" identity. Lifespan and empowerment theories were used to harvest meanings from these themes. Implications for nursing practice and research were examined based on study findings. Participatory action research offers an approach for future studies in which researchers advocate for transgender individuals and remove obstacles to their health care access.

Application of a marketing concept to patient-centered care: co-producing health with heart failure patients.

Increasing numbers of patients are being treated for heart failure each year. One out of four of the heart failure patients who receives care in a hospital is readmitted to the hospital within 30 days of discharge. Effective discharge instruction is critical to prevent these patient readmissions. Co-production is a marketing concept whereby the customer is a partner in the delivery of a good or service. For example, a patient and nurse may partner to co-produce a patient-centered health regimen to improve patient outcomes. In this article we review the cost of treating heart failure patients and current strategies to decrease hospital readmissions for these patients along with the role of the nurse and the concept of co-producing health as related to heart failure patients. Next we describe our study assessing the degree to which discharge processes were co-produced on two hospital units having a preponderance of heart failure patients, and present our findings indicating minimal evidence of co-production. A discussion of our findings, along with clinical implications of these findings, recommendations for change, and suggestions for future research are offered. We conclude that standardized discharge plans lead to a mindset of 'one size fits all,' a mindset inconsistent with the recent call for patient-centered care. We offer co-production as a patient-centered strategy for customizing discharge teaching and improving health outcomes for heart failure patients.

Relocation stress syndrome in older adults transitioning from home to a long-term care facility: myth or reality?

Relocation stress syndrome is a nursing diagnosis characterized by symptoms such as anxiety, confusion, hopelessness, and loneliness. It usually occurs in older adults shortly after moving from a private residence to a nursing home or assisted-living facility. The primary purpose of this study was to validate the symptoms of relocation stress syndrome. Eight nursing home residents and 8 assisted-living facility residents were interviewed 2 to 10 weeks after admission, when symptoms of relocation stress syndrome are most likely to appear. Results of this study indicate that the incidence of relocation stress syndrome may be overestimated. More accurate diagnosis and treatment of depression in older adults is needed.

Age and ageism: inhabiting the lives of healthy older adults through video narratives.

When applied humanities is used as a framework, the educational innovation described in this article provides a more balanced view of aging than occurs in most nursing programs. Five video narratives and focused discussion questions, intended to mitigate the "otherness" of old age, are described. Rationales and sample student responses are provided.

Ethics committees in long-term care facilities.

Biomedical ethical dilemmas occur in long-term care facilities (LTCFs), particularly in the absence of residents' advance directives. Ethics committees are required in hospitals and long-term care facilities accredited by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO), but many LTCFs do not have JCAHO accreditation. A survey of LTCFs in one county in a Southwestern state found that only 29% of those LTCFs responding had an organized ethics committee. This article discusses the purpose, membership, and meetings of an ethics committee in LTCFs. A sample process for resolving a biomedical ethical dilemma is presented. Nurses can initiate the development of an ethics committee using available resources or combining resources with other local LTCFs. The ethics committee should consider the education of all persons involved to facilitate resolution of clinical ethical dilemmas.
