RESUMO

INTRODUCTION: Vascular dementia and heart failure (HF) are common co-existing conditions among adult populations. Each condition requires extensive home caregiving from family caregivers, especially those in rural Appalachia. This study aimed to assess caregivers' burden and their physical and mental health status, as well as explore their experiences and needs. METHODS: This study used an exploratory mixed-methods design combining quantitative and qualitative research (N = 20 caregivers). We collected data using questionnaires, short-answered interviews, and focus group discussions. The multivariable generalized linear model (GLiM) was used to analyze quantitative data; content analysis was used for qualitative data. RESULTS: The average age of family caregivers was 64.95 years. The generalized linear model showed that the caregiving burden was associated with caregivers' depression/anxiety (r = 0.68, P < .001) and their number of dementia caregiving years (r = 0.54, P < .05). Caregivers' poor physical health status was associated with better preparedness for HF and dementia home caregiving (r = 0.52, P < .05) and male caregivers (r = -0.46, P < .01). Caregivers' mental health status was associated with depression/anxiety (r = -0.80, P < .001). The qualitative data identified key caregiving themes: emotional impact and physical demands of caregiving, lack of help in rural areas, dealing with multiple disease progression, and relationship changes with their loved ones. CONCLUSION: Caregiving burden was associated with caregivers' home care responsibilities and the need for support. Nurse-led home caregiving preparedness interventions tailored for family caregivers of patients with HF and dementia in rural areas are recommended.

RESUMO

Objectives: This study aimed to describe the "how-to" details and processes for developing and evaluating a short-term international student research and education program. Methods: This study included two parts: development and implementation, and evaluation of the program. A foreign doctoral nursing student requested to visit the West Virginia University School of Nursing for research training and academic teaching experience. The global nursing program coordinator and the lead mentor met and identified the program basis and team participants. Learning activities were related to this student's interest in older adults and in-home end-of-life care, included four contents: research; educational engagement; practice/clinical engagement; special activities & professional development training and courses. The program evaluation was conducted at the end of the six-month visit using a focus group and an anonymous short survey. Participants (n = 10) included the host university's faculty, graduate students, and one short-term international student. Results: Content analysis of the participant's short survey answers and the focus group discussion resulted in three themes: 1) lessons learned from participating in the program (enhanced diversity in education and research, gaining new global healthcare knowledge, and self-reflection on and promoting cultural awareness); 2) program barriers and challenges (the visa application process, the English language barrier, the lack of public transportation in the town, and scheduling conflicts); and 3) strategies to overcome these barriers and challenges (adding cultural diversity information into curriculum; attending English proficiency with others in the class; using different communication techniques; continuous collaboration with the University's Office of Global Affairs for the Visa application process; providing interactive experiences). All participants rated their engagement in the program as very satisfactory (Mean = 4.67, SD = 0.50), and highly impacted their nursing skills in research, teaching, and clinical practice (Mean = 4.67, SD = 0.50). Conclusions: All the participants have gained some experience in this program, which can be used for future teaching guidance. Further, international nursing students need assistance to adjust and thrive in the host university learning community. Faculty must be culturally sensitive, understand the visiting foreign nursing student' learning needs, and advocate for an environment suitable for enhancing the students' learning.

RESUMO

Fungal pathogens are one of the major reasons for biotic stress on rice (Oryza sativa L.), causing severe productivity losses every year. Breeding for host resistance is a mainstay of rice disease management, but conventional development of commercial resistant varieties is often slow. In contrast, the development of disease resistance by targeted genome manipulation has the potential to deliver resistant varieties more rapidly. The present study reports the first cloning of a synthetic maize chitinase 1 gene and its insertion in rice cv. (Basmati 385) via Agrobacterium-mediated transformation to confer resistance to the rice blast pathogen, Pyricularia oryzae. Several factors for transformation were optimized; we found that 4-week-old calli and an infection time of 15 minutes with Agrobacterium before colonization on co-cultivation media were the best-suited conditions. Moreover, 300 µM of acetosyringone in co-cultivation media for two days was exceptional in achieving the highest callus transformation frequency. Transgenic lines were analyzed using molecular and functional techniques. Successful integration of the gene into rice lines was confirmed by polymerase chain reaction with primer sets specific to chitinase and hpt genes. Furthermore, real-time PCR analysis of transformants indicated a strong association between transgene expression and elevated levels of resistance to rice blast. Functional validation of the integrated gene was performed by a detached leaf bioassay, which validated the efficacy of chitinase-mediated resistance in all transgenic Basmati 385 plants with variable levels of enhanced resistance against the P. oryzae. We concluded that overexpression of the maize chitinase 1 gene in Basmati 385 improved resistance against the pathogen. These findings will add new options to resistant germplasm resources for disease resistance breeding. The maize chitinase 1 gene demonstrated potential for genetic improvement of rice varieties against biotic stresses in future transformation programs.

RESUMO

INTRODUCTION: Older adults living alone in rural areas frequently experience health declines, social isolation, and limited access to services. To address these challenges, our medical academic university supported a quality improvement project for developing and evaluating the Visiting Neighbors program in two rural Appalachian counties. Our Visiting Neighbors program trained local volunteers to visit and guide rural older adults in healthy activities. These age-appropriate activities (Mingle, Manage, and Move- 3M's) were designed to improve the functional health of older adults. The program includes four in-home visits and four follow-up telephone calls across three months. PURPOSE: The purpose of this paper was to describe the 3M's Visiting Neighbors protocol steps guiding the quality improvement procedures relating to program development, implementation, and evaluation. METHODS AND MATERIALS: This Visiting Neighbors study used a single-group exploratory quality improvement design. This program was tested using quality improvement standards, including collecting participant questionnaires and visit observations. RESULTS: Older adults (> 65 years) living alone (N = 30) participants were female (79%) with a mean age of 82.96 (SD = 7.87) years. Volunteer visitor participants (N = 10) were older adult females. Two volunteer visitors implemented each visit, guided by the 3M's activities manual. All visits were verified as being consistently delivered (fidelity). Enrollment and retention data found the program was feasible to conduct. The older adult participants' total program helpfulness ratings (1 to 5) were high (M = 51.27, SD = 3.77). All volunteer visitor's program helpfulness ratings were also high (M = 51.78, SD = 3.73). DISCUSSION: The Visiting Neighbors program consistently engaged older Appalachian adults living alone in the 3M's activities. The feasibility and fidelity of the 3M's home visits were verified. The quality improvement processes included engaging the expert advisory committee and rural county stakeholders to ensure the quality of the program development, implementation, and evaluation.

RESUMO

PURPOSE: Sex differences may exist in opioid use disorder (OUD) treatment. This study examined the treatment effects of buprenorphine/naloxone (BUP/NX) and methadone (MET) on the Clinical Opiate Withdrawal Scale (COWS) score in individuals with OUD and tested whether the associations differ by sex. METHOD: We performed a secondary analysis of the data from the National Drug Abuse Treatment Clinical Trials Network (CTN) protocol-0027. A total of 1269 participants (861 males and 408 females) being aged 18 or older with OUD were randomly assigned to receive BUP/NX (n = 740) or MET (n = 529). The paired t test was initially used to compare the COWS scores between pre-dose and post-dose for BUP/NX and MET treatments, separately. The linear mixed model was used to examine the changes in COWS score adjusted for baseline demographic, substance use, and mental health disorders. The interaction of sex and treatment was detected and stratified analysis by sex was conducted. RESULTS: The paired t test showed that both BUP/NX and MET treatments significantly reduced the COWS scores (p values <0.0001). BUP/NX revealed higher COWS scores than MET (p = 0.0008) and females demonstrated significantly higher COWS scores than males (p = 0.0169). Stratified by sex, BUP/NX compared with MET revealed higher COWS scores only in males (p = 0.0043), whereas baseline amphetamines use disorder and major depressive disorder were significantly associated with COWS scores in females (p = 0.0158 and 0.0422, respectively). CONCLUSIONS: Both BUP/NX and MET are effective in decreasing opioid withdrawal symptoms via COWS scores, however, treatment plans for OUD by clinical providers should consider sex differences.

RESUMO

PURPOSE: To examine the associations of age when first substance use and early-onset substance use before age 18 with age at onset (AAO) of hypertension. METHODS: This study included 19,270 individuals with AAO of hypertension from the 2015-2019 National Survey on Drug Use and Health. Age when first use of 10 substance use variables included alcohol, daily cigarettes, cigars, smokeless tobacco, marijuana, cocaine, hallucinogens, lysergic acid diethylamide (LSD), inhalants, and methamphetamine use. The outcome was AAO of hypertension and variable cluster analysis was used to classify the exposures and outcome. Substance use status was classified into three categories: early-onset substance use (first used substance before age 18), late-onset substance use (first used substance after age 18), and never used. RESULTS: The mean AAO of hypertension was 42.7 years. Age when first use of 10 substance use variables had significant correlations with AAO of hypertension (all p values < 0.001). Individuals with early-onset alcohol, cigars, smokeless tobacco, marijuana, hallucinogens, inhalants, cocaine, LSD, and methamphetamine use revealed significantly earlier onset of hypertension than those never used. Compared with never used substances, the Cox regression model showed that early-onset alcohol, smokeless tobacco, marijuana, inhalants, and methamphetamine use had an increased risk of AAO of hypertension [hazard ratio (HR) (95%CI) = 1.22 (1.13, 1.31), 1.36 (1.24, 1.49), 1.85 (1.75, 1.95), 1.41 (1.30, 1.52), and 1.27 (1.07,1.50), respectively]. CONCLUSION: These findings suggest that intervention strategies or programs focusing on preventing early-onset substance use before age 18 may delay the onset of adult hypertension.

RESUMO

BACKGROUND: This study evaluated the prevalence of emergency room (ER) visits, given numerous substance use and mental health variables in the past year. METHODS: Data from 5206 emergency room visits out of 27,170 adults were extracted from the 2020 National Survey on Drug Use and Health. Oblique principal component cluster analysis was used to classify 39 substance use and mental health variables into disjoint clusters. RESULTS: In 2020, the overall prevalence of ER visits was 21.9 %. Being female, age above 65 years, with insurance, low income and low education levels, and being African American increased the risk of ER visit. Nine clusters were made out of 39 substance use and mental health variables. Multivariate stepwise logistic regression analysis showed 15 substance use and mental health variables were significantly associated with ER visits including heavy alcohol use past 30 days in cluster 3, nicotine dependence and cigarettes use in cluster 4, major depressive episode, serious psychological distress, and suicidal plans in past year in cluster 5, any psychotherapeutics use in cluster 7, tranquilizers use and lorazepam products use in cluster 8, and any pain reliever, pain reliever misuse, hydrocodone products use, oxycodone products use, tramadol products use, and codeine products use in cluster 9. CONCLUSIONS: Several substance use and mental health problems, including nicotine dependence, illicit drugs, and serious mental health problems were among the common reasons for ER visits. These findings suggest the effective use of ER as the venue to implement interventions for substance use and mental health.

RESUMO

ABSTRACT: The objective of this research was to explore the perceptions of nurses regarding patients with substance use disorder (SUD), healthcare provided, and desired resources to care for this population properly. This study used a cross-sectional, descriptive design. Data were collected via an anonymous 12-item survey and three open-ended questions. Data were analyzed using descriptive statistics and conventional content analysis. Nurses with less than 1 year of experience reported more significant challenges when caring for patients with SUD. These challenges included difficulties in managing pain, implementing alternative pain management techniques, and knowing who to contact when problems occur. The study revealed many needs of nurses to provide compassionate care for patients with SUD. Findings indicate a need for education for nurses, especially novice nurses, who care for patients with SUD.

RESUMO

Few studies have focused on sleep apnea and substance use disorders with co-occurrence of anxiety disorder and depression. This study included a total of 270,227 adults, 9268 with co-occurrence of anxiety disorder and depression in the past year, from the combined 2008-2014 National Survey on Drug Use and Health (NSDUH) data, which are the latest datasets with measures of anxiety disorder and sleep apnea. Weighted multinomial logistic regression analyses were used to estimate the associations between anxiety disorder and depression and their co-occurrence. Comorbidity was highly prevalent: 40.4% of those with depression also met the criteria for anxiety disorder, whereas 51.8% of those with anxiety disorder also met the criteria for depression. The prevalences of anxiety only and co-occurrence increased from 2008 to 2014. The prevalences of anxiety disorder only, depression only, and co-occurrence of anxiety disorder and depression in individuals with sleep apnea were 4.4%, 12.9%, and 12.2%, respectively, and the prevalences in substance use disorders were 6.4%, 9.4%, and 10.7%, respectively. The results showed that sleep apnea, substance use disorders, and nicotine dependence were significantly associated with increased odds of anxiety disorder, depression, and co-occurrence (all p values < 0.0001). Furthermore, several chronic diseases (asthma, bronchitis, hypertension, and heart disease) were associated with the co-occurrence of anxiety disorder and depression. These findings suggest clinicians and other healthcare providers consider screening for depression and anxiety with sleep apnea and substance use disorders for improved therapeutic outcomes.

RESUMO

Heart failure and vascular dementia have similar underlying pathologies, so it is not uncommon for one condition to exist in the presence of the other. In-home management of each condition is challenging for patients and their family caregivers, but when both conditions are present, those challenges are amplified. The purpose of this case report is to describe one family's experience managing heart failure and vascular dementia at home. A mixed method of semistructured interviews and short surveys was used to examine the health status and well-being of the patient and family caregiver. Data were derived from individual interviews and standardized measures. Survey results revealed the patient had worsening dementia, poor heart failure-related quality of life, poor spiritual well-being, depression, and diminished self-care. The caregiver reported poor physical and mental health. Interview data revealed frustration dealing with worsening symptoms, inadequate information about disease progression, and fear of an unknown future. Additionally, the patient suggested strategies to deal with challenges. Families managing heart failure and vascular dementia need easy-to-understand education from healthcare providers, on-going assessments, and early referrals to support services including those provided by social workers and chaplains.

RESUMO

OBJECTIVE: This study examined the association between preconception substance use and unintended pregnancy in a large, nationally representative sample of women. METHODS: In this cross-sectional study, we used data from the Pregnancy Risk Assessment Monitoring System (PRAMS) comprising, 74,543women who had birth during 2016-17. Logistic regression was used to assess the independent association of unintended pregnancy overall and by subtypes to preconception substance use (smoking and other nicotine/tobacco use, alcohol consumption, and use of cannabis, illicit/recreational drugs) and specific medication including prescription opioids, antidepressants and over the counter pain relief. RESULTS: Overall, 41% of pregnancies were unintended. Nearly 57% of participants reported alcohol consumption during the preconception period, with 32% indicating binge drinking, 17% reported preconception smoking, and 10% cannabis use. Unintended pregnancy was significantly associated with substance use, including smoking (adjusted odds ratio [AOR]:1.5, 95% confidence interval [CI]: 1.4-1.6); as well as the use of other nicotine/tobacco (AOR:1.4, 95% CI: 1.3-1.5); cannabis (AOR: 1.9, 95% CI: 1.5-2.3); illicit/recreational drugs (AOR:1.7, 95% CI: 1.2-2.4), prescription opioids (AOR:1.4, 95% CI: 1.02-1.9), and prescription antidepressants (AOR 1.8, 95% CI: 1.1-3.0). The likelihood of unintended pregnancy was significantly elevated with heavy smoking, heavy alcohol consumption, and binge drinking. Analyses by unintended pregnancy subtype yielded similar results. CONCLUSIONS: Preconception substance use was significantly and positively associated with unintended pregnancy. Evidence-based interventions are needed addressing substance use behavior and effective contraceptive use to prevent unintended pregnancy and related adverse effects on maternal and child health.

RESUMO

Fidelity (consistency of intervention implementation) is essential to rigorous research. Intervention fidelity maintains study internal validity, intervention reproducibility, and transparency in the research conduct. The purpose of this manuscript is to describe intervention fidelity strategies/procedures developed for a pilot study testing a new palliative care nursing intervention (FamPALcare) for families managing advanced lung disease. The procedures described herein are based on the fidelity best practices recommendations from the NIH Consortium. An evidence-based checklist guided observational ratings of the fidelity procedures used and the intervention content implemented in each intervention session. Descriptive data on how participants understood (received), enacted, or used the intervention information were summarized. The fidelity checklist observational scores found ≥93% of the planned intervention content was implemented, and the fidelity strategies were adhered to consistently during each intervention session. The small variation (7%) in implementation was expected and related to participants' varying experiences, input, and/or questions. The helpfulness scale items include participants' ability to use home care resources, to anticipate and manage end-of-life symptoms, and to use Advance Directive forms. The high ratings (M = 4.4) on the 1-5 (very helpful) Likert Helpfulness Scale verified participants utilized the information from the intervention. Furthermore, there was an improvement in patients' breathlessness scores and completion of Advance Directive forms at 3 months after baseline. It is essential to plan intervention fidelity strategies to use throughout a study and to report fidelity results.

RESUMO

There is a gap in current research on common factors that impact patients with advanced heart failure (HF). The purpose of this secondary data analysis was to explore associations of those factors with three empirically verified measures of HF-related clinical, physical, and mental health status. Baseline data of 198 advanced systolic HF (EF < 40%) patients were analyzed. Patients were 61.6% male, with a mean age of 62.3 (SD = 13.2) years. The multivariable general linear modeling results indicated that patients who had poorer scores on HF-related clinical status were those who had sleep apnea (ß = -6.6, p < .05), daytime sleepiness (ß = -9.4, p < .01), four or more comorbidities (ß = -11.8, p < .001), and depression (ß = -18.7, p < .001). Depression was associated with all three measures of HF-related health status. These findings alert nurses to assess for sleep apnea and to use known screening measures for daytime sleepiness, depression, and comorbidities.

RESUMO

BACKGROUND: Many factors contribute to continuous positive airway pressure (CPAP) nonadherence, affecting health care burden. The original CPAP-SAVER study enrolled 66 CPAP-naive participants and showed high 1-month adherence and significantly higher apnea beliefs and CPAP attitude for the intervention group. PURPOSE AND METHODS: Thirty-three participants from the original CPAP-SAVER study were recruited for a 3-year follow-up to determine adherence, examine the intervention effect, and identify adherence-associated factors. RESULTS: Adherence rates dropped to 54.5% at 3 years, with a significant decrease in CPAP use hours (t = -2.37, p = .024) and nights (t = -4.05, p < .001). Group differences in beliefs and attitude were not sustained; however, beliefs (r = 0.57) and attitude (r = 0.44) were significant factors associated with adherence. Life satisfaction was significantly higher at present compared with before wearing CPAP (t = 5.17, p < .001). IMPLICATIONS FOR PRACTICE: The authors recommend intervention with a focus on apnea beliefs, CPAP attitude, and long-term support to promote CPAP adherence. Focus on CPAP attitude and beliefs and enhanced support early in the obstructive sleep apnea (OSA) treatment trajectory may promote long-term adherence and subsequently reduce the health care burden of OSA disease.

RESUMO

This study is the first report on the biosynthesized iron oxide nanoparticles (IONPs) which mediate in-vitro callus induction and shoot regeneration in economically important recalcitrant chickpea crop (Cicer arietinum L.). Here, we used leaf extract of Cymbopogon jwarancusa for the synthesis of IONPs in order to achieve a better biocompatibility. The bioactive compounds in C. jwarancusa leaf extract served as both reducing and capping agents in the fabrication process of IONPs. Field emission scanning electron microscopy (FE-SEM) revealed rods like surface morphology of IONPs with an average diameter of 50±0.2 nm. Energy-dispersive X-ray spectroscopy (EDS) depicted formation of pure IONPs with 69.84% Fe and 30.16% O2. X-ray diffractometry (XRD) and attenuated total reflectance-fourier transform infrared (ATR-FTIR) validate the crystalline structure, chemical analysis detect the presence of various biomolecular fingerprints in the as synthesized IONPs. UV-visible absorption spectroscopy depicts activity of IONPs under visible light. Thermo-gravimetric analysis (TGA) displayed thermal loss of organic capping around 500°C and confirmed their stabilization. The biosynthesized IONPs revealed promising results in callus induction, shoot regeneration and root induction of chickpea plants. Both chickpea varieties Punjab-Noor 09 and Bittle-98 explants, Embryo axes (EA) and Embryo axes plus adjacent part of cotyledon (EXC) demonstrated dose-dependent response. Among all explants, EXC of Punjab-Noor variety showed the highest callogenesis (96%) and shoot regeneration frequency (88%), while root induction frequency was also increased to 83%. Iron content was quantified in regenerated chickpea varieties through inductively coupled plasma-optical emission spectrometry. The quantity of iron is significantly increased in Punjab-Noor regenerated plants (4.88 mg/g) as compare to control treated plants (2.42 mg/g). We found that IONPs enhance chickpea growth pattern and keep regenerated plantlets infection free by providing an optimum environment for rapid growth and development. Thus, IONPs synthesized through green process can be utilized in tissue culture studies in other important recalcitrant legumes crops.

RESUMO

The current study focuses on the usage of bio synthesized zinc oxide nanoparticles to increase the tissue culture efficiency of important forage grass Panicum virgatum. Zinc being a micronutrient enhanced the callogenesis and regeneration efficiency of Panicum virgatum at different concentrations. Here, we synthesized zinc oxide nanoparticles through Cymbopogon citratus leaves extract to evaluate the effect of zinc oxide nanoparticles on plant regeneration ability in switchgrass. X-ray diffraction (XRD) and attenuated total reflectance-Fourier transform infrared (ATR-FTIR) validate phase purity of green synthesize Zinc oxide nanoparticles whereas, electron microscopy (SEM) has illustrated the average size of particle 50±4 nm with hexagonal rod like shape. Energy dispersive spectroscopy X-ray (EDS) depicted major peaks of Zn (92.68%) while minor peaks refer to Oxygen (7.32%). ZnO-NPs demonstrated the incredibly promising results against callogenesis. Biosynthesized ZnO-NPs at optimum concentration showed very promising effect on plant regeneration ability. Both the explants, seeds and nodes showed dose dependent response and upon high doses exceeding 40 mg/L the results were recorded negative, whereas at 30 mg/L both explants demonstrated 70% and 76% regeneration frequency. The results conclude that ZnO-NPs enhance the plant growth and development and tailored the nutritive properties at nano-scale. Furthermore, eco-friendly approach of ZnO-NPs synthesis is strongly believed to improve in vitro regeneration frequencies in several other monocot plants.

RESUMO

AIM: To pilot test a home end-of-life and palliative care intervention for family caregivers and patients with rare advanced lung diseases and to estimate effect-size for the power analysis in a future clinical trial. DESIGN: This study uses a parallel randomized control trial. Families are randomly assigned to the intervention group or the control group in a 1:1 fashion. METHODS: The study population includes patients with rare advanced lung diseases and their family caregivers who are involved in patients' home care. The control group receives standard care through their hospital or outpatient clinics. The intervention group receives standard care plus 2-weekly home end-of-life and palliative care coaching by experienced community nurses. Primary outcome is breathlessness measured by shortness of breath scale. Secondary outcomes are: (a) caregivers' anxiety and depression measures; (b) the presence of patient's signed advance directives in the medical record or not; and (c) Helpfulness of intervention measured by self-report Helpfulness scale. The study was funded in October 2018 and received ethical Institutional Review Board approval in February 2019. DISCUSSION: West Virginia has one of the highest incidence rates of lung disease deaths in the nation. However, there is inadequate home end-of-life and palliative care for this underserved population. This is an initial interventional study of nurse-led coaching home-based palliative care for rare advanced lung diseases in rural Appalachia. Developing research collaboration with clinicians is essential for enrolment. Enrolment was successful due to regular meetings with pulmonologists who screened patients per the study inclusion criteria in their specialty clinic and made direct referrals to the research assistants. Results of this study will be used in the future trial. IMPACT: The findings will contribute to the evidence-based home nursing care, planning for family/patient preferences and supportive end-of-life palliative care for managing advanced lung diseases at home. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT03813667; registered January 23, 2019. https://clinicaltrials.gov/ct2/show/NCT03813667.

RESUMO

Adult patients on hemodialysis experience a high prevalence of poor oral health and periodontitis. The chronic inflammation associated with poor periodontal health can increase the risk of cardiovascular disease and mortality among patients on hemodialysis. A systematic review of research articles published from 2012-2018 was conducted to synthesize current literature on the subject. Forty-three articles were identified. Findings were summarized into two categories: clinical measurements and lifestyle/quality of life. We suggest the development, implementation, and evaluation of oral health nursing interventions and periodontal treatments among patients on hemodialysis.
