RESUMEN

Social media has become an integral part of everyday life and revolutionized how older adults communicate and interact with others. The aim of the current review was to identify and synthesize quantitative studies addressing the potential relationship between social media use and depression in older adults. Medline, CINAHL, and PsycINFO databases were used to identify studies performed up to July 2020. Keywords identified were depression, social media use, and older adults. A nuanced relationship was revealed between social media use and depression in older adults. There were noted differences in the conceptualization of social media use. The reviewed studies lacked exploration of structural characteristics, examination of content, and quality of interactions in older adults' social media use. Health variables, social factors, and age cohort differences could influence the relationship between social media use and depression. Further studies are needed to enhance the understanding and explore the benefits and potential disadvantages of social media use in older adults.

RESUMEN

BACKGROUND: Patients with acute coronary syndrome (ACS) with symptoms matching their expectations of a heart attack are more likely to use emergency medical services (EMS) than not. OBJECTIVE: To determine whether presenting symptom clusters are associated with EMS use in ACS patients and if EMS use or symptom clusters are associated with prehospital delay. METHODS: This secondary analysis used data from the PROMOTION trial, a randomized clinical trial that enrolled 3522 subjects with a history of or at risk for ACS from 5 sites in the United States, Australia, and New Zealand. Subjects were randomized to usual care or an educational intervention to reduce prehospital delay. During the 2-year follow-up, subjects admitted for ACS were asked about symptoms, time of symptom onset, and mode of transportation to the hospital. Symptoms were grouped into classic ACS, pain symptoms, and stress symptoms clusters. RESULTS: Of 3522 subjects enrolled, 331 sought care for ACS during follow-up; 278 had transportation mode documented; 121 (44%) arrived via EMS. Classic ACS plus pain symptoms (adjusted odds ratio [AOR], 2.66; P = .011), classic ACS plus stress symptoms (AOR, 2.61; P = .007), and classic ACS plus both pain and stress symptoms (AOR, 3.90; P = .012) were associated with higher odds of EMS use versus classic ACS symptoms alone. Emergency medical services use resulted in a 68.5-minute shorter median delay (P = .002) versus non-EMS use. Symptom clusters were not predictive of delay time in the adjusted model (P = .952). DISCUSSION: Although chest symptoms were the most prevalent symptoms for most (85%), the combination of classic ACS symptoms with other symptom clusters was associated with higher EMS use. Further research is needed to determine whether a combination of symptom clusters helps patients correctly interpret ACS symptoms to better understand how symptom clusters influence EMS use.

RESUMEN

BACKGROUND: Individuals living with mechanical circulatory support (MCS) devices are confronted with risks for catastrophic outcomes such as stroke and systemic infection. Considering these complexities, ongoing advance care planning (ACP) is important for shared decision making. OBJECTIVE: The purpose of this study was to describe how experiences of the MCS trajectory informed decision making about ACP. METHODS: All aspects of the research were guided by constructivist grounded theory. Focused conversations were conducted with a semistructured interview guide. RESULTS: A total of 24 community-dwelling patients living with MCS were interviewed (33% female; mean age, 60.6 years; 50% White). Participants were implanted with MCS (average duration, 29.8 months; bridge to transplant, 58%). Reflected in the narratives were tensions between initial expectations of living with the device in contrast with the realities that emerged over time. A crucial finding was that ACP decision making pivoted around the growing awareness of uncertainties in the MCS trajectory. Yet, clinicians were perceived to be silent in initiating ACP, and their reticence was understood as a sign of encouragement to hold on to hope for a heart transplant. The complex and dynamic decision-making processes around ACP were organized into the theory of pivoting uncertainties. CONCLUSIONS: In this sample, patients were ready to share their concerns about the uncertainties of living with MCS and waited for MCS clinicians to initiate ACP. The theory of pivoting uncertainties is useful for elucidating the ebb and flow of ACP and lending clinicians' guidance for opportunities to initiate these sensitive conversations.

RESUMEN

Background: Infants born with single ventricle heart disease require in-home medicalized care during the interstage period (time between the first and second staged heart surgery). These caregivers rely on extended family, friends, and hired caretakers to provide respite time. However, the coronavirus pandemic removed these families' options due to stay-at-home and social distancing directives. We explored the caregivers' experiences during the interstage period, including impacts on their lifestyle, as they managed their infants' critical needs during the coronavirus disease 2019 pandemic. Method: In-person or telephonic interviews of 14 caregivers interviewed once or twice were conducted between November 2019 and July 2020. Constructivist Grounded Theory methodology guided both data collection and analysis for the inductive and abductive exploration of caregivers' experiences. Results: Data analysis led to the development of 2 concepts: Accepting and adapting to a restrictive home environment and Reconciling what is and what is yet to come. Refinement of the relationship between the 2 concepts led to the development of a theory grounded in the words and experiences of the participants called: A Continuous Process of Compromise. Conclusions: Our findings increase understanding of caregivers' experiences related to psychosocial and lifestyle impacts and the need for additional support during the interstage period.

RESUMEN

BACKGROUND: While support from family caregivers is essential in the care of patients with heart failure (HF), caregiving places a considerable burden on family caregivers. We examined the preliminary effects of cognitive behavioral therapy (CBT) for caregivers of individuals with HF. METHODS: In this pilot randomized controlled trial, patients with HF and their primary family caregivers (30 dyads) were randomized into CBT (n = 15) or general health education (GHE, n = 15) groups. Caregivers received 8 weekly individual sessions of either CBT (intervention) or GHE (attention control condition). Caregivers completed questionnaires at baseline, post-intervention, and 6 months. Saliva samples collected from caregivers at baseline and post-intervention were analyzed for salivary cortisol. The cortisol awakening response (CAR) and area under the curve (AUC) were calculated using log-transformed cortisol values. We analyzed data from 26 (14 receiving CBT and 12 receiving GHE) caregivers who received at least one session of CBT or GHE (modified intention-to treat) using linear mixed models. Each model included time, study group, and time-by-study group interaction as fixed effects. RESULTS: Patients were older (66.94 ± 14.01 years) than caregivers (55.09 ± 15.24 years), and 54% of patients and 54% of caregivers were female. Most caregivers (58%) were spouses. A total of 14 (93%) CBT and 12 (80%) GHE participants received at least 1 session (p = .60), and 11 (73%) CBT and 11 (73%) GHE participants completed all 8 sessions (p = 1.00). There were no significant between-group differences in change for salivary cortisol or psychological outcomes. However, the CBT group had significant within-group improvements in perceived stress (p = .011), stress symptoms (p = .017), depression (p = .002), and anxiety (p = .006) from baseline to post-intervention, while the control group had no significant within-group change in the outcomes except for anxiety (p = .03). The significant improvements observed in the CBT group lasted for 6 months. No adverse effects were observed. CONCLUSIONS: In this pilot trial, although between-group differences in change were not significant, CBT resulted in significant improvements in some psychological outcomes with no improvement in the control group. Our findings suggest the potential of the intervention to alleviate psychological distress in HF caregivers. Further examination in larger randomized trials is warranted.

RESUMEN

BACKGROUND: People living with mechanical circulatory support (MCS) are at risk for catastrophic complications that require advance care planning (ACP) as part of the preimplantation work up. Palliative care consultants are a mandatory and essential component of the MCS team tasked to enhance conversations. However, in reality, there is often a serious deficiency of ACP communication after the initial implant counseling. A better understanding of opportunities and challenges in ACP can mobilize intensive care unit and step-down nurses to bridge this gap in crucial communication. OBJECTIVES: To identify and describe MCS individuals' perceptions of opportunities and challenges for ongoing ACP communication. METHODS: A constructivist grounded theory study was conducted with 24 MCS individuals from 2 medical centers in Southern California. Semi-structured interviews were audio recorded, transcribed, and reviewed for accuracy. The data were systematically analyzed through 3 rounds of coding. RESULTS: MCS clinicians, supportive others, and peers with MCS were identified as stakeholders in ongoing communication. Four categories of opportunities and challenges for ongoing ACP were synthesized from the narratives: identifying context and timing, sharing information, understanding of ACP, and assessing satisfaction. All participants reported a preference for MCS clinicians, including nurses, to initiate ACP conversations. CONCLUSION: Understanding opportunities and challenges is key to facilitating ongoing ACP discussions among MCS patients. MCS-trained nurses are positioned to address the dearth of ongoing ACP by facilitating these sensitive discussions. The personal accounts of this sample serve to guide future research and structure training to prepare MCS clinicians for primary palliative care.

RESUMEN

BACKGROUND: Caring for infants after the first-stage palliative surgery for single-ventricle heart disease bring challenges beyond the usual parenting responsibilities. Current studies fail to capture the nuances of caregivers' experiences during the most critical "interstage" period between the first and second surgery. OBJECTIVES: To explore the perceptions of caregivers about their experiences while transitioning to caregiver roles, including the successes and challenges associated with caregiving during the interstage period. METHODS: Constructivist Grounded Theory methodology guided the collection and analysis of data from in person or telephonic interviews with caregivers after their infants underwent the first-stage palliative surgery for single-ventricle heart disease, and were sent to home for 2-4 months before returning for their second surgery. Symbolic interactionism informed data analyses and interpretation. RESULTS: Our sample included 14 parents, who were interviewed 1-2 times between November, 2019 and July, 2020. Most patients were mothers (71%), Latinx (64%), with household incomes <$30K (42%). Data analysis led to the development of a Grounded Theory called Developing a Sense of Self-Reliance with three categories: (1) Owning caregiving responsibilities despite grave fears, (2) Figuring out how "to make it work" in the interstage period, and (3) Gaining a sense of self-reliance. CONCLUSIONS: Parents transitioned to caregiver roles by developing a sense of self-reliance and, in the process, gained self-confidence and decision-making skills. Our study responded to the key research priority from the AHA Scientific Statement to address the knowledge gap in home monitoring for interstage infants through qualitative research design.

RESUMEN

BACKGROUND AND AIMS: HTN affects nearly 50% of U.S. adults and is the leading modifiable cardiovascular risk factor. A healthy diet and exercise can improve BP control, but adherence to these interventions is low. We tested whether a multimodal mind-body program, Mindful Awareness Practices (MAP) could improve BP and lifestyle behaviors associated with HTN when compared to a Health Promotion Program (HPP). METHODS: Adults with BP >120/80 were randomized to MAP or HPP. Outcome measurements of BP, self-reported diet, and exercise were analyzed with intent-to-treat group comparisons using repeated measures linear mixed models. RESULTS: There was an MAP-HPP between-group difference in interactions of time-by-systolic BP (P = 0.005) and time-by-diastolic BP (P = .003). The mean drops in SBP from baseline to week 13 for the MAP group was 19 mm Hg (138 ± 15 mm Hg-119 ± 6 mm Hg) compared to 7 mm Hg (134 ± 18 mm Hg-127 ± 22 mm Hg) in the HPP group. Similarly, a greater reduction in DBP was observed in the MAP group compared to the HPP group, 12 mm Hg (89 mm Hg ± 11-77 ± 7 mm Hg) and 1 mm Hg (81 ± 16 mm Hg-80 ± 18 mm Hg), respectively. Mediational analysis of the MAP group showed the total effect of mindfulness practice minutes on SBP with indirect effect (ab) of -.057 was significant, resulting in a 40% lower SBP for total effect (c) compared to direct (c') effect alone. The mediational model suggests MAP has a modest positive influence on participants initiating lifestyle behavior change, which partially explains the greater reduction in BP by the MAP group. CONCLUSION: Our findings suggest a multimodal mind-body program involving mindfulness practice may improve BP control in adults with HTN.

RESUMEN

OBJECTIVES: Obstructive sleep apnoea (OSA) is a risk factor for hypertension (HTN), but the clinical progression of OSA to HTN is unclear. There are also sex differences in prevalence, screening and symptoms of OSA. Our objective was to estimate the time from OSA to HTN diagnoses in females and males. DESIGN: Retrospective analysis of electronic health records (EHR) over 10 years (2006-2015 inclusive). SETTING: University of California Los Angeles (UCLA) Health System in Los Angeles, California, USA. PARTICIPANTS: 4848 patients: females n=2086, mean (SD) age=52.8 (13.2) years; males n=2762, age=53.8 (13.5) years. These patients were selected from 1.6 million with diagnoses in the EHR who met these criteria: diagnoses of OSA and HTN; in long-term care defined by ambulatory visits at least 1 year prior and 1 year subsequent to the first OSA diagnosis; no diagnosis of OSA or HTN at intake; and a sleep study performed at UCLA. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome measure in each patient was time from the first diagnosis of OSA to the first diagnosis of HTN (OSA to HTN days). Since HTN and OSA are progressive disorders, a secondary measure was the relationship between OSA to HTN time and age (OSA to HTN=ß1×Age+ß0). RESULTS: The median (lower and upper quartiles) days from OSA to HTN were: all -532 (-1439, -3); females -610 (-1579, -42); and males -451 (-1358, 0). Older age in both sexes was associated with less time to a subsequent HTN diagnosis or more time from a prior HTN diagnosis (ß1 days/year: all -16.9, females -18.3, males -15.9). CONCLUSIONS: HTN was on average diagnosed years prior to OSA, with a longer separation in females. Our findings are consistent with underscreening of OSA, more so in females than males. Undiagnosed OSA may delay treatment for the sleep disorder and perhaps affect the development and progression of HTN.

RESUMEN

INTRODUCTION: The Dynamic Appraisal of Situational Aggression (DASA) is an assessment tool that has been validated to predict violent or aggressive behavior in psychiatric inpatient settings. Its validity has not been established for use in the emergency department. METHODS: The DASA was implemented within the electronic health record of an academic medical center with inpatient psychiatric services. A retrospective analysis was conducted using Spearman rank-correlation coefficients to compare a final risk score with the subsequent occurrence of violence or aggression, defined as the use of hard leather physical restraints or the administration of intramuscular sedative medication. A receiver operating characteristic curve was used to summarize the predictive accuracy of the tool to assess aggression in behavioral health patients in the emergency department. RESULTS: A total of 3,433 scores were analyzed, representing 1,548 patients. The DASA had predictive validity with increasing scores comparing all tested cutoff scores against incidence of violence and aggression. The area under the curve comparing scores of 0 versus more than 0 was 0.79. The median time to subsequent aggression was 110 minutes. DISCUSSION: The DASA has predictive validity for use in evaluating behavioral health patients in the ED setting in an urban academic medical center. The tool is capable of predicting violence or aggression within a time frame conducive to the implementation of noninvasive measures. The DASA should be tested in other ED settings to further establish its predictive validity.

RESUMEN

Background: Spontaneous preterm delivery (sPTD) is associated with a twofold increased risk of future maternal cardiovascular disease. We hypothesized that women with sPTD would demonstrate greater vascular dysfunction postpartum compared to women with term delivery. Materials and Methods: In a case-controlled, matched pilot study, we enrolled 20 women with sPTD (gestation ≤34 weeks), and 20 term control women (gestation ≥39 weeks) were matched for age (±5 years), parity, ethnicity, and route of delivery. Vascular function, serum lipids, C-reactive protein, and interleukin-6 were completed within 24-72 hours postpartum. Statistical analysis included paired t-tests based on match and mixed effects linear regression models and adjusted for potential confounders. Results: The mean age for sPTD and term controls was 33 ± 6 years and 32 ± 6 years, respectively. Women with sPTD had significantly lower augmentation index-75 (24.1% ± 16.1% vs. 39.9% ± 15.2%, p = 0.001) and central pulse pressure (29.1 ± 5.4 mmHg vs. 34.6 ± 4.7 mmHg, p = 0.004), but no difference in pulse wave velocity (5.1 ± 1.6 m/s vs. 5.6 ± 1.5 m/s, p = 0.12) compared to controls. Women with sPTD had significantly lower high-density lipoprotein cholesterol (59.4 ± 12.5 mg/dL vs. 67.6 ± 13.1 mg/dL, p = 0.035) compared to controls. Analysis of chorioamnionitis and magnesium sulfate did not alter the results. Conclusions: Women with sPTD have signs of lower smooth muscle tone in the early postpartum period compared to women with term delivery. Further research is required to understand mechanistic pathways in sPTD and future maternal cardiovascular disease risk.

RESUMEN

BACKGROUND: Hookah smoking is marketed to youth as a harmless alternative to cigarettes. Although cigarette smoking acutely impairs endothelial function, the effect of smoking fruit-flavored hookah tobacco is unknown. Because charcoal traditionally is used to heat the hookah tobacco in the waterpipe, hookah smoke delivers tobacco toxicants and nicotine plus charcoal combustion products: not only carbon-rich nanoparticles, oxidants that may destroy nitric oxide and impair endothelial function, but also large amounts of carbon monoxide (CO), a putative vasodilator molecule. METHODS: To test the acute effect of hookah smoking on endothelial function, in young adult hookah smokers (n=30, age 26±1 years, mean±SE), we measured plasma nicotine, exhaled CO, and brachial artery flow-mediated dilation (FMD) before and after charcoal-heated hookah smoking. To remove the effect of charcoal combustion, the same measurements were performed when the same flavored hookah tobacco product was heated electrically (n=20). As a positive internal control, we studied age-matched cigarette smokers (n=15) who smoked 1 cigarette. To isolate the effect of the CO boost on FMD, hookah smokers (n=8) inhaled a 0.1% CO gas mixture to approximate their CO boost achieved with charcoal-heated hookah smoking. RESULTS: Nicotine levels increased similarly with all types of smoking, whereas exhaled CO increased 9- to 10-fold more after charcoal-heated hookah than after either electrically heated hookah or cigarette smoking. FMD did not decrease after smoking charcoal-heated hookah but instead increased by +43±7% ( P<0.001). In contrast, FMD decreased by -27±4% ( P<0.001) after smoking electrically heated hookah, comparable to the decrease after cigarette smoking. FMD increased markedly by 138±71% ( P<0.001) after breathing CO gas, 2.8 times more than the increase induced in the same subjects after smoking charcoal-heated hookah ( P<0.001), despite comparable increases in exhaled CO (24±1 versus 28±3 ppm, hookah versus CO). CONCLUSIONS: Smoking hookah tobacco, similar to cigarette tobacco, acutely impairs endothelial function. With traditional charcoal-heated hookah smoking, the acute endothelial dysfunction is masked by high levels of carbon monoxide, a potent vasodilator molecule generated by charcoal combustion. With respect to large-artery endothelial function, smoking hookah is not harmless. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov .

RESUMEN

Hookah (waterpipe) smoking is rapidly increasing in popularity worldwide. Despite being heavily advertised in the media as a healthier alternative to cigarettes, the toxicology of hookah smoke suggest otherwise. Cigarette smoking unequivocally causes an acute increase in arterial stiffness, but whether hookah does the same is unknown. In 48 young healthy habitual hookah but not cigarette smokers, we measured heart rate, peripheral and central blood pressure, carotid-femoral pulse wave velocity (measure of arterial stiffness), aortic augmentation index (measure of wave reflection), plasma nicotine, and exhaled carbon monoxide before and after ad lib hookah smoking. Hookah smoking increased heart rate by +16 ± 1 beats/min and mean brachial arterial pressure by +6 ± 1 mm Hg (both p <0.05, mean ± SE). Most importantly, it increased carotid-femoral pulse wave velocity and aortic augmentation index by +0.66 ± 0.09 m/s-1 and +8.76 ± 3.99%, respectively (p <0.05, mean ± SE), denoting increased acute arterial stiffness. These vascular effects were accompanied by increases in plasma nicotine concentration (+5.8 ± 1.2 ng/ml, p <0.05) and expired carbon monoxide (+25.44 ± 1.68 ppm, p <0.05). All these parameters were unchanged during time-control studies (n = 14). Thus, in contrast to effective media marketing of hookah as a safer alternative to cigarettes, the present study shows for the first time that in young adult hookah smokers, a single hookah smoking session causes an acute increase in arterial stiffness of comparable magnitude to what has been previously reported for cigarettes. Further research is warranted to determine whether habitual hookah smoking accelerates the age-dependent development of hypertension and its cardiovascular complications.

RESUMEN

BACKGROUND: Acute allograft rejection appears to be associated with increases in QT/QTc intervals. OBJECTIVES: To determine the relationship between acute allograft rejection and electrocardiogram changes in patients undergoing an orthotopic heart transplant. METHODS: The study population comprised 220 adult patients undergoing heart transplant and enrolled in the NEW HEART study. Electrocardiograms obtained within 72 hours of endomyocardial biopsy were analyzed; electrocardiograms obtained fewer than 10 days after transplant surgery were excluded. Repeated-measures analysis was performed with statistical models including effects for rejection severity (mild and moderate/severe) and time trends independent of rejection status. RESULTS: The 151 male and 69 female transplant recipients (mean age [SD], 54 [13] years) had 969 biopsy/electrocardiogram pairs: 677 with no rejection, 280 with mild rejection, and 12 with moderate/severe rejection. Moderate to severe organ rejection was associated with significant increases in QRS duration (P < .001), QT (P = .009), QTc (P = .003), and PR interval (P = .03), as well as increased odds of right bundle block branch (P = .002) and fascicular block (P = .009) occurring. CONCLUSIONS: Moderate to severe acute allograft rejection was associated with electrocardiographic changes after transplant surgery. Studies are needed to assess the value of computerized electrocardiogram measurement algorithms for detecting acute allograft rejection.

RESUMEN

Cardiovascular disease (CVD) risk factors are well established. However, little is known about a woman's cardiovascular response to pregnancy, which appears to be an early marker of future maternal CVD risk. Spontaneous preterm delivery (sPTD) has been associated with a ≤3-fold increased risk of maternal CVD death later in life compared with having a term delivery. This review focuses on 3 key areas to critically assess the association of sPTD and future maternal CVD risk: (1) CVD risk factors, (2) inflammatory biomarkers of interest, and (3) specific forms of vascular dysfunction, such as endothelial function and arterial stiffness, and mechanisms by which each may be linked to sPTD. The association of sPTD with subsequent future maternal CVD risk suggests that a woman's abnormal response to pregnancy may serve as her first physiological stress test. These findings suggest that future research is needed to understand why women with sPTD may be at risk for CVD to implement effective interventions earlier in a woman's life.

RESUMEN

BACKGROUND: Perceived control has been associated with improved mental health and health-related quality of life (HRQOL) in cardiac populations. However, this concept has not been well-studied in heart transplant groups. AIMS: We examine the relationship of perceived control to symptoms of anxiety and depression and HRQOL after transplant. We also examine the extent to which anxiety and depressive symptoms mediate the relationship between perceived control and HRQOL. METHODS: Our cross-sectional analysis included 113 adult heart transplant patients from the NEW HEART study. High versus low perceived control groups were determined by median split for chi-square and t-test analyses. Hierarchical multiple linear regression models were used to examine the influence of perceived control on symptoms of depression and anxiety and HRQOL. Mediation analyses included Baron and Kenny's four-step regression approach and Preacher and Hayes' bootstrapping technique to test the indirect effect of perceived control on HRQOL. RESULTS: Heart transplant patients who reported lower perceived control were more likely to be female ( p=0.003), and had significantly more depressive symptoms ( p<0.001) and anxiety ( p<0.001), and lower HRQOL ( p<0.001) than those with higher perceived control. Perceived control was a significant predictor in regression models of depressive and anxiety symptoms and HRQOL. In mediation analyses, depressive and anxiety symptoms mediated the effect of perceived control on HRQOL. CONCLUSION: Perceived control is associated with improved depressive and anxiety symptoms and HRQOL after transplant. The relationship between perceived control and HRQOL is mediated by depressive and anxiety symptoms. Future interventions should target perceived control to improve overall HRQOL.

RESUMEN

OBJECTIVES: We evaluated the reliability of the Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) in heart transplant (HT) recipients and explored its usefulness in predicting post-transplant outcomes. BACKGROUND: Pre-transplant psychosocial and behavioral risk is associated with post-transplant clinical outcomes. SIPAT is a risk assessment tool created for pre-transplant psychosocial evaluation. METHODS: Via retrospective chart review, three examiners applied the SIPAT to 51 adult HT recipients. Examiners blinded to SIPAT scores extracted data and interviewed clinicians for one-year post-transplant outcomes. Analysis included Intra-class correlation coefficient (ICC), Pearson's correlation coefficient and Chi-square. RESULTS: SIPAT demonstrated strong inter-rater reliability (ICC = 0.89, 95% CI = 0.76-0.96). Compared to those with SIPAT ratings of "Excellent/Good", the "Minimally Acceptable Candidate/High Risk" group was more likely to miss clinic visits (p = 0.004). CONCLUSIONS: The SIPAT tool had strong IRR. Less favorable SIPAT ratings were associated with nonadherence to clinic visits. Further study is warranted to determine association of SIPAT ratings to clinical outcomes.

RESUMEN

BACKGROUND: Little attention has focused on gender differences in cardiac comorbidities and outcomes in patients undergoing orthotropic heart transplant. OBJECTIVE: The objective of this study was to investigate gender differences at baseline and during follow-up among heart transplant patients. METHODS: An observational cohort within the NEW HEART study was evaluated to determine gender differences in relation to age, coexisting cardiac comorbidities, and outcomes. Differences were assessed by t-test, Fisher's exact test, and logistic regression analysis. RESULTS: Male transplant recipients ( n = 238) were significantly older than female recipients ( n = 92), with a greater percentage over 60 years of age (45% vs. 24%, p = 0.0006). Males were more likely to have hypertension (63% vs. 49%, p = 0.034), dyslipidemia (62% vs. 45%, p = 0.006), a history of smoking (52% vs. 35%, p = 0.009), and diabetes (42% vs. 21%, p = 0.0002). Analysis of endomyocardial biopsies obtained during the 1-year follow-up period demonstrated that women averaged more episodes of acute rejection than men (3.9 vs. 3.0, p = 0.009). While most episodes of rejection were mild, women were more likely than men to have episodes of moderate or severe rejection (14% vs. 5%, p = 0.012) and to be hospitalized for acute rejection (15% vs. 6%, p = 0.013). There were no significant differences in mortality. CONCLUSIONS: Men were more likely than women to be older and to have diabetes, dyslipidemia, hypertension, and a history of smoking. Women were more likely to experience moderate or severe allograft rejection and to be hospitalized for acute rejection. Future investigation of the reasons for these gender differences is warranted and may improve clinical care of women undergoing cardiac transplantation.

RESUMEN

Characterizing how physical and psychological symptoms interact in heart transplant recipients may lead to advances in therapeutic options. This study examined associations between pain and major depression. METHOD: A cross-sectional study was conducted with adult heart transplant recipients. Pain was measured with the bodily pain domain of the Short Form-36 Health Survey and psychological distress with the Kessler Psychological Distress Scale (K-10). The Mini International Neuropsychiatric Interview, version 6.0, was used to identify participants meeting the criteria for major depression. Hierarchical linear regression was used to determine if there was an association between pain and major depression, controlling for pharmacological treatment of depression, severity of psychological distress, and clinical characteristics including immunosuppression medication which may induce pain as a side effect. RESULTS: Average pain score of the 48 heart transplant recipients was 43 ( SD ± 10, range 0-100, lower scores indicate worse pain), with moderate pain reported by 39% ( n = 19). Major depression was associated with worse pain ( R2 change = 36%, ß = -16, 95% confidence interval [CI] = [-30, -4], p = .012). Pharmacological treatment for depression was associated with better pain scores ( R2 change = 1.5%, ß = 13, 95% CI [4, 23], p = .006). CONCLUSIONS: Heart transplant recipients with major depression had worse pain after controlling for pharmacological treatment of depression, severity of psychological distress, and clinical characteristics. Thus, it is imperative that clinicians devising a treatment regimen for pain in heart transplant recipients take into account co-occurring depression and vice versa.

RESUMEN

PURPOSE: The aim of this study was to assess the validity and reliability of psychological screening tools in outpatient heart transplant recipients. METHODS: Forty-eight heart transplant recipients completed the Patient Health Questionnaire 9-item scale (PHQ-9), Generalized Anxiety Disorder 7-item Scale (GAD-7), Kessler Psychological Distress 10-item Scale (K-10) and Medical Outcomes Short Form 36-item Health Survey. A structured psychological interview (Mini International Neuropsychiatric Interview Version 6) was conducted after completion of the questionnaires. Internal consistency, criterion validity and construct validity of the PHQ-9, GAD-7 and K-10 were evaluated. RESULTS: Internal consistency supported the reliability of the screening tools. The optimal cut-off on the PHQ-9 for depression was 10 (sensitivity=0.86; specificity=0.93). A score of 6 on the GAD-7 maximized sensitivity (0.75) and specificity (0.89) for anxiety. A score of 17 on the K-10 was the optimal cut-off for diagnosis of either anxiety or depression (sensitivity=0.83; specificity=0.84). Increasing scores on the screening tools were associated with lower health-related quality of life. CONCLUSION: Psychometric analyses support the reliability and validity of the PHQ-9, GAD-7 and K-10 as screening tools for detection of anxiety and depression in heart transplant recipients.
