RESUMO

Purpose of Review: Insomnia is the most common sleep disorder experienced by older adults. There is a wide range of pharmacological and non-pharmacological treatment options in existing literature. The purpose of this systematic review was to synthesize randomized controlled trials of insomnia treatment modalities for adults aged 55 and older over the last 5 years. We searched four databases, and after screening, there were 34 full-text manuscripts that met the inclusion/exclusion criteria. Recent Findings: We found non-pharmacological interventions, including exercise and behavioral/psychoeducational therapies, remain effective and favorable. Complementary and alternative therapies ranged across studies and warrant further testing in larger, more diverse samples. Dual orexin receptor antagonist medications were tested in a few studies with positive benefits for sleep and minimal side effects. Finally, measures of insomnia/sleep disturbance outcomes varied among the studies, with the Pittsburgh Sleep Quality Index being used most frequently. Summary: Non-pharmacological interventions for insomnia in older adults are effective, and some newer medications may be safer, with less side effects, at managing insomnia in this population.

RESUMO

OBJECTIVES: To examine sleep quality and self-reported causes of sleep disturbance among patients with breast cancer at diagnosis and one year later. SAMPLE & SETTING: 486 of 606 patients with histologically confirmed breast cancer completed a Pittsburgh Quality Sleep Index (PSQI) survey at the time of diagnosis and again one year later. METHODS & VARIABLES: In this secondary data analysis, descriptive statistics were computed for seven PSQI components and its global score. Wilcoxon signed-rank tests and McNemar's tests were used. Self-reported reasons for sleep disturbances were summarized. RESULTS: PSQI scores significantly increased from baseline (mean = 6.75) to one-year follow-up (mean= 7.12), indicating worsened sleep. Sleep disturbance and onset latency scores increased, whereas sleep efficiency decreased. The two most frequently reported reasons for sleep disturbance were waking up late in the night or early in the morning (more than 50%) and needing to use the bathroom (49%). Feeling too hot and experiencing pain three or more times per week were reported by participants at baseline and one year later. IMPLICATIONS FOR NURSING: Results can aid in monitoring patient response to treatment methods and formulating benchmarks to manage sleep problems.

RESUMO

Very little is known about contraceptive behavior in Appalachia, a large geographic region in the eastern United States where even basic prevalence estimates of contraceptive use/nonuse are lacking. This study characterizes contraceptive behavior among Appalachians, including contraceptive use, reasons for use, and methods used; contraceptive nonuse and reasons for nonuse; and attitudes about contraception, including acceptability. This is a secondary analysis of a subsample of survey data collected on sexual and reproductive health attitudes, behaviors, and needs among reproductive-age women (18-49 years) living in the Appalachian region (n = 332). Results identify rates of contraceptive use (66.6%) and nonuse (33.1%) among Appalachian residents. Methods used most frequently included those that did not require prescription (i.e., external condoms and natural family planning methods) though many reported the use of intrauterine devices (IUDs). Among nonusers, fear of side effects from contraception and ambivalence towards pregnancy were most commonly selected as the most important reason for not using contraception. Contraception was considered acceptable by this sample overall, and these acceptability attitudes were significantly associated with contraceptive behavior.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic and resulting instructions to stay home and social distance enhanced concerns of the impact of social isolation on the physical and mental well-being of older adults. Eighteen community-dwelling older adults participated in interviews describing their experiences early in the COVID-19 pandemic. Participants experienced loss of activities, routines, and social connection, and feelings of worry and uncertainty. Nevertheless, participants were hopeful about the future and demonstrated resilience in overcoming boredom as they became intentional in finding new activities and using technology to maintain connection with others. Older adults may need support in such situations to manage boredom and uncertainty and avoid social isolation. [Journal of Gerontological Nursing, 49(6), 27-32.].

RESUMO

OBJECTIVE: To examine the relationship between intrauterine devices (IUDs) and bacterial vaginosis (BV) through an integrative review of the current literature. DATA SOURCES: CINAHL, MEDLINE, Health Source, Evidence-Based Medicine's Cochrane Central Registry of Controlled Trials, Embase, and Web of Science databases were searched. STUDY SELECTION: Cross-sectional, case-control, cohort, quasi-experimental, and randomized controlled trials examining copper (Cu-IUD) and levonorgestrel (LNG-IUD) use in reproductive- age users with BV occurrence confirmed with Amsel's criteria or Nugent scoring were included. Articles included were published in the past 10 years. DATA EXTRACTION: Fifteen studies met criteria, after an initial search identified 1,140 potential titles, and two reviewers assessed 62 full-text articles for inclusion. DATA SYNTHESIS: Data were categorized into three groups: retrospective descriptive cross-sectional studies identifying point prevalence of BV among IUD users; prospective analytic studies examining BV incidence and prevalence among Cu-IUD users; and prospective analytic studies examining BV incidence and prevalence among LNG-IUD users. CONCLUSION: Synthesis and comparison of studies were difficult because of disparate study designs, sample sizes, comparator groups, and inclusion criteria for individual studies. Synthesis of data from cross-sectional studies showed that all IUD users combined may have an increased point prevalence of BV compared with non-IUD users. These studies did not delineate LNG-IUDs from Cu-IUDs. Findings from cohort and experimental studies suggest a possible increase in BV occurrence among Cu-IUD users. Evidence is lacking to show an association between LNG-IUD use and BV.

RESUMO

Quality of life (QoL) is one of the outcomes that can be measured as a component of the required standards for sleep facility accreditation by the American Academy of Sleep Medicine. Utilization of a psychometrically robust QoL instrument is recommended; however, clinicians face a challenge balancing psychometric properties with questionnaire completion and scoring characteristics. This article provides an overview of common QoL instruments as a reference for clinicians when selecting a QoL tool for use in the clinical setting for adult patients with obstructive sleep apnea. CITATION: Colvin L, Collop N, Lorenz R, Morgenthaler T, Weaver TE. Examining the feasibility of adult quality-of-life measurement for obstructive sleep apnea in clinical settings: what is the path forward for sleep centers? J Clin Sleep Med. 2023;19(6):1145-1155.

RESUMO

OBJECTIVES: Dementia family caregivers report poor sleep and mood, typically attributed to chronic stress and managing frequent daily stressors. Although many studies use global retrospective reports of these indicators, the current study examines mechanisms linking sleep, negative affect, stress biomarkers, and high-/low-stress contexts at the daily level, from the biopsychosocial perspective of stressor exposure and reactivity. METHOD: One hundred seventy-three caregivers (Mage = 61.97, SD = 10.66) were providing care at home and used adult day services (ADS) at least 2 days a week. Caregivers reported their bedtime, wake time, sleep quality, and nighttime problems of the person with dementia (PwD) daily for eight consecutive days, concurrently reporting noncare stressors, negative affect, and providing five salivary cortisol samples per day. We conducted multilevel analysis to examine whether caregiver sleep characteristics overnight (i.e., total time in bed, quality, and PwD sleep problems) were associated with their anxious and depressive symptoms on days where ADS were utilized versus non-ADS days (i.e., low stress vs. high stress), and whether cortisol daily total output as area under the curve (AUCg) mediated the direct associations, at the within- and between-person levels. RESULTS: On high-stress (i.e., non-ADS) days when caregivers had a longer time in bed than usual the night before, they were less anxious on the following day; the direct association was statistically mediated through lower cortisol AUCg during the day. DISCUSSION: Staying longer in bed than usual before an upcoming high-stress day may help dementia family caregivers better regulate cortisol stress reactivity and anxious symptoms.

RESUMO

The hetereoscorpionate ligands bis(pyrazol-1-yl)acetic acid (Hbpza) and bis(3,5-dimethylpyrazol-1-yl)acetic acid (Hbdmpza) are reacted with [Sn(OAc)2] or [Sn(acac)2] to yield the corresponding Sn(II) complexes. A single crystal X-ray determination for the in solution monomeric complex [Sn(bpza)2] (1a) revealed a dinuclear molecular structure [Sn2(bpza)4] (1b), with κ3-N,N,O-coordinated bpza ligands at each of the Sn(II) and two bpza ligands µ-bridging between the Sn(II) centres. The molecular structure of [Sn(bdmpza)2] (2) exhibits a homoleptic bisligand complex with both ligands displaced by the free electron pair, which is proven by DFT calculations. Oxidation of complex 2 in an attempt to synthesize a homoleptic Sn(IV) complex leads to the formation of [Sn(bdmpza)F3] (3). In addition, homoleptic bisligand gallium complexes [Ga(bdmpza)2][ClO4] (4) and [Ga(bpza)2][GaCl4] (5) were prepared and characterized by 71Ga NMR and IR spectroscopy as well as by X-ray crystallography.

RESUMO

AIM: This study was designed to investigate the feasibility, acceptability, and preliminary efficacy of a nurse-led communication intervention among surrogates in the intensive care unit (ICU) guided by the COMFORT (Connect; Options; Making meaning; Family caregivers; Openings; Relating; Team) communication model. BACKGROUND: As frontline communicators, nurses experience communication difficulties with surrogates who face complex informational and emotional barriers when making decisions for critically ill patients in the ICU. However, research on effective nurse communication focusing on both curative and end-of-life (EOL) care is lacking in the literature. DESIGN: A single-centre two-group pretest-posttest quasi-experiment. METHOD: The total sample included 41 surrogates of adult ventilated patients. Twenty participants were allocated to the intervention group who received a daily 20-min telephone call with content based on the COMFORT communication model. Twenty-one participants comprised the control group who received usual care. Participants completed a questionnaire before and after the study measuring satisfaction, anxiety and depression, decisional conflict, and quality of communication. The Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) checklist was followed for nonrandomised controlled trials. RESULT: The intervention was feasible, with 19 of 20 surrogates completing the follow-up surveys, and 48 telephone conversations completed (48% of the planned phone calls). Surrogates' satisfaction was higher in the intervention group than in the control group after adjusting for the selected covariates (25.43 and 24.15, respectively; p = .512). Preliminary efficacy outcomes favouring the intervention included quality of communication with healthcare providers, but not surrogates' perceived depression/anxiety and decisional conflicts. CONCLUSION: Implementation of the intervention is feasible, acceptable, and favourable among surrogates to improve quality of communication with healthcare providers in the ICU. Further research is needed to determine whether the intervention could be implemented by nurses to improve surrogates' outcomes in other ICUs.

RESUMO

Sleep is critical to physical and mental health for people of all ages, but older adults are particularly vulnerable to the consequences of poor sleep health. The purpose of this pilot study was to explore patterns of sleep and the relationships between circadian rhythm disorders and quantity of life in 34 community-dwelling older adults. Participants were primarily female, and single. Of participants, 44% reported poor sleep quality, and 29% had a circadian rhythm disorder. Those with circadian rhythm disorders had lower physical health quality of life score than other participants although this was not significant. No differences were seen in mental health quality of life scores. Further research is needed to explore sleep and circadian rhythm disorders in this population to target interventions to improve sleep quality.

RESUMO

BACKGROUND: Approximately 795,000 Americans experience a new or recurrent stroke every year, and it remains one of the leading causes of disability worldwide. Patient engagement in rehabilitation and physical activity has been associated with improvements in functional outcomes during inpatient rehabilitation. There is limited knowledge of the barriers and facilitators to patients' engagement in stroke rehabilitation. METHODS: An integrative review with a systematic approach was conducted to explore the current available literature on barriers and facilitators to patient engagement in stroke inpatient rehabilitation. RESULTS: Twenty-five studies were included in the final review. Four major themes described the identified barriers and facilitators: (1) stroke impact, (2) self-efficacy, (3) therapeutic relationship, and (4) motivating factors. Individualized patient-centered goal setting was a commonly studied intervention found to successfully increase engagement. CONCLUSION: Engagement in stroke rehabilitation is associated with improved patient outcomes. Using the identified themes from this review, nurses can develop focused interventions aimed at reducing barriers and increasing stroke patient engagement.

RESUMO

BACKGROUND: Community-based nurse-led interventions have the potential to impact admission rates in Heart Failure (HF) patients. No reviews have focused on identifying the best combination or duration of interventions to reduced hospital admissions. OBJECTIVE: To assess the impact of nurse-led community-based interventions on hospital admission rates in HF patients. METHODS: This study was conducted following Whittmore and Knafl's Methodology. CINAHL, PubMed, Embase and Web of Science and hand searching were used to identify articles. Selected studies were analyzed using the Matrix Method. RESULTS: Telemonitoring, home visits, phone calls, care coordination, and telemedicine were identified as interventions in 10 studies. Telemonitoring with phone calls or care coordination was not impactful. Studies with significant results included those with multiple interventions, APN-led, or conducted over one year. CONCLUSIONS: The combination of intervention type and length are important factors when designing interventions for HF management. More research is needed on intervention length.

RESUMO

BACKGROUND: Opioid use among reproductive-age women has greatly increased, resulting in high rates of opioid-exposed pregnancies, which are associated with negative outcomes, such as neonatal abstinence syndrome. Prevention of unintended pregnancy among opioid users is a critical pathway to reducing opioid-exposed pregnancies; however, little is known about pregnancy intention in this group. This article estimates the prevalence of unintended pregnancy among opioid-using women, thereby supporting efforts to develop interventions to reduce unintended pregnancy. METHODS: A systematic literature search was conducted in PubMed, Web of Science, PsycINFO, and CINAHL, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses framework. Reference lists of articles were searched. Eligibility criteria included reported unintended pregnancy rates within a population of opioid-using women of reproductive age. The search was completed in July 2018 and updated in October 2019. RESULTS: We identified 115 citations, screened 64 titles/abstracts, reviewed 31 full-text articles, and included 12 articles for this review. Rates of unintended pregnancy in opioid users were estimated in two ways, across the lifetime and for a current pregnancy, depending on study samples. Rates for both groups were high, with rates among currently pregnant opioid-using women (85%) compared with 45% among the general population. CONCLUSIONS AND IMPLICATIONS: Unintended pregnancy rates in opioid-using women were strikingly high, indicating a critical need for intervention. Routine inclusion of pregnancy planning in opioid treatment care is indicated. Education regarding contraception and opioid treatment services is essential for nurses in these settings. Family planning and opioid treatment efforts can be optimized by care coordination, with focus on nurse training for screening and patient education.

RESUMO

BACKGROUND: Visitor restrictions caused challenges for family members when their loved ones had coronavirus disease (COVID-19) and were ventilated. Limited studies have reported on family members' experiences and support needs. AIM: To explore the experiences and support needs of family members of ventilated COVID-19 patients in the intensive care unit (ICU). DESIGN: Exploratory, qualitative design, using in-depth individual telephone interviews, and analyzed using thematic analysis. SETTING/PARTICIPANTS: Ten family members of adult COVID-19 patients in the ICU. RESULT: Seven key themes represented family members' experiences: (a) reactions to the COVID-19 diagnosis, (b) COVID-19 as a destabilizing force on the family unit, (c) COVID-19's effects on bereavement outcomes, (d) desperately seeking information, (e) family member needs, (f) conflicting feelings about video calls, and (g) appreciation of care. Family members' feelings about the patient's diagnosis and how the virus was contracted exacerbated their stress and anxiety. They struggled to feel informed about care that they could not witness and had difficulty understanding information. Family members reported that video calls were unhelpful. While these experiences made them question the quality of care, they expressed their appreciation of the frontline healthcare providers taking care of their loved ones. CONCLUSION: The stress and uncertainty of family members of critically ill patients with COVID-19 were influenced by their inability to feel connected to the patient and informed about care. Healthcare providers should assess each individual family's burden and preferences, and this should include establishing structured, timely, and consistent communication regarding patient care during the pandemic including early referral to palliative care.

RESUMO

We explored the feasibility of a mindfulness plus sleep education intervention, SleepWell!, delivered via videoconference compared to onsite among adults with MS. A non-randomized wait-list control design was used. Participants wore actigraphy watches and kept sleep diaries for seven days pre- and post intervention. Questionnaires were completed pre-intervention, post-intervention, and three months post-intervention. One group was conducted onsite. Three groups participated via videoconference. Attrition among videoconference groups was 23% compared to 57% in the onsite group. Within group analysis showed moderate-to-large effect sizes on sleep efficiency (d=0.78) and total sleep time (d=0.54) in the videoconference groups. One-way repeated measures ANOVA post-hoc analysis suggested small-to-medium effect over three months on sleep quality (ηp2 =0.28), physical health quality of life (ηp2 =0.42), mental health quality of life (ηp2 =0.13), and mindfulness (ηp2 =0.29). Results indicate feasibility of providing our intervention via videoconferencing. Preliminary analysis suggests that SleepWell! improves sleep and mindfulness among adults with MS.

RESUMO

Adult women with multiple sclerosis (MS) can benefit from innovative mindfulness-based interventions designed and structured with understanding and consideration of the multifaceted challenges these women face on a daily basis. The purpose of this qualitative descriptive study was to explore the experience of participating in an online or traditional onsite 8-week, once a week, Mind Body Stress Reduction combined with Sleep Retraining course among women living with MS to establish online course acceptability. Braun and Clarke's Reflexive Thematic Analysis method was used to analyze focus group interview data. Time and length for both courses was found acceptable, camaraderie and interconnectedness were essential, having choice regarding course delivery format was important, and being provided with organized learning materials at the course start in a binder or packet was considered imperative. Acceptability was established for both the online and onsite formats.

RESUMO

Patient activation is an important aspect of self-management for adults with chronic non cancerous health conditions (CHC). However, there is limited evidence about which measures of patient activation and healthrelated quality of life are most useful to clinicians. This systematic review examined regarding the types of measures used to evaluate a patient's readiness for self-management including patient activation and healthrelated quality of life (HRQOL). Two such as measurements are the Patient Activation Measure (PAM) and overall PROMIS® Global health. Ten articles were identified which included measurement of patient activation and HRQOL. The results indicate that HRQOL is evaluated with various measurement tools. Most researchers agree that patient activation and the measurement of global HRQOL positively contribute to successful self-management strategies.

RESUMO

Carbon-rich ruthenium allenylidene complexes bearing either a hexaarylbenzene (HAB) or a hexa-peri-hexabenzocoronene (HBC) substituent were synthesised. This was achieved via the corresponding propargyl alcohols with HAB and HBC substituents, which were accessible via 3 or 4 step reaction cascades. Reaction of the propargyl alcohols HC[triple bond, length as m-dash]C(OH)Ph(HAB) and HC[triple bond, length as m-dash]C(OH)Ph(HBC) with [RuCl(η5-C5H5)(PPh3)2] yielded the complexes [Ru(η5-C5H5)([double bond, length as m-dash]C[double bond, length as m-dash]C[double bond, length as m-dash]C(HAB)(Ph))(PPh3)2]PF6 and [Ru(η5-C5H5)([double bond, length as m-dash]C[double bond, length as m-dash]C[double bond, length as m-dash]C(HBC)(Ph))(PPh3)2]PF6. The latter of which shows interesting π-π-stacking behaviour in the solid state as well as aggregation in solution.

RESUMO

Objectives High-stakes exams are a source of chronic stress that may adversely affect nursing students' thinking, behavior, and overall health. The purpose of this study was to explore the relationships of perceived stress, physiological stress reactivity, and exit exam performance. Methods A within-subjects design allowed measurement of perceived stress, salivary cortisol, and salivary alpha amylase in pre-licensure nursing students under two different conditions: a high-stakes exit exam and a low-stakes homework assignment. Results Perceived stress and salivary alpha amylase were significantly higher after the high-stakes exam compared to the homework condition. Perceived stress after the exam was correlated with lower exam score. Conclusion Study findings suggest that in response to a high-stakes exam, prelicensure nursing students experience high levels of perceived stress coupled with sympathetic activation but not activation of the hypothalamic-pituitary adrenal axis.

RESUMO

The current study examined factors related to fatigue in family caregivers of individuals with dementia using a cross-sectional design to collect subjective and objective data. Findings indicated that caregivers' sleep quality, difficulty falling asleep, and depression, as well as care-recipients' functionality, were associated with family caregivers' fatigue. Regression analysis indicated that only sleep quality significantly predicted caregivers' fatigue. Study findings suggest fatigue is common among family caregivers of individuals with dementia and may be related to sleep quality. The level of fatigue identified in the current study warrants further study with larger and more diverse samples. [Journal of Gerontological Nursing, 46(9), 14-18.].
