Internet-based behavioral change and psychosocial care for patients with cardiovascular disease: a review of cardiac disease-specific applications

BACKGROUND: Web-based interventions (WBIs) seem to be an efficacious method of addressing behavioral and psychosocial maladjustment among patients with chronic illness (eg, diabetes), behavioral concerns (eg, smoking cessation), and psychologic maladjustment (eg, panic disorder). Cardiology seems particularly well suited to the application of WBIs given its strong association with behavioral (eg, lifestyle) and cognitive (eg, stress and coping) factors. To date, few studies have been published that explore the use of WBIs on psychosocial and quality of life variables among populations with cardiac disease. OBJECTIVE: The purpose of this study is to review the use of WBIs in patients with cardiovascular disease to date, and to provide recommendations as to how future WBIs can be developed specifically to meet the needs of different populations with heart disease (eg, recipients of implantable cardioverter defibrillators, patients with congestive heart failure, and patients with congenital heart disease). CONCLUSIONS: We conclude that, although limitations exist, WBIs are a reasonable modus of improving patient outcomes.     

Adenoviral infection in hematopoietic stem cell transplantation: early diagnosis with quantitative detection of the viral genome in serum and urine

Early diagnosis and prompt introduction of effective therapy are imperative to manage systemic, often fatal adenoviral (AdV) disease following hematopoietic stem cell transplantation (SCT). We evaluated the usefulness of real-time polymerase chain reaction (PCR) in the diagnosis of AdV disease in SCT recipients. Seven SCT recipients, including three with AdV disease, were retrospectively evaluated for AdV genome detection. In serum specimens, the AdV genome was detected at >10(3) copies/ml in the pre-SCT period in two of the five recipients studied. These two patients subsequently developed AdV disease. The three patients with AdV disease had high levels of >10(5) copies/ml during the 4-6 weeks post-SCT period. In none of these patients was the AdV genome detected in urine specimens in pre-SCT period. However, three recipients with detectable urinary levels during the period 1-2 weeks post-SCT subsequently developed AdV disease. Regarding the outcome, two of the three patients with AdV disease died of progressive renal failure. Our results suggest that quantitative determination of the AdV genome in serum and urine is useful to identify patients at high risk of developing AdV disease. Prospectively applied, these measures are expected to improve the dismal outcome of AdV disease in SCT recipients.     

Psychosocial adjustment of pediatric patients after allogeneic stem cell transplantation.

The purpose of this study was to assess the psychosocial adjustment of patients who had been treated with allogeneic stem cell transplantation (SCT) in our clinic. Selection criteria for patients were to be aged 14-30 years at the time of the follow-up, to be at least 2 years post-SCT and to have a very good knowledge of German. Among 31 eligible patients, 26 participated (84% response rate). The patients were between 15 and 27 years old and were on average 7 years (range 2-13) post-SCT. Research instruments consisted of a demographic questionnaire and various subscales of established psychological measures for which data from a sample of bone cancer survivors and population norms were available. About 35% of patients showed high levels of anxiety, 62% appeared to be extremely sensitive and vulnerable, and 35% showed strong, unfulfilled needs in their love lives. In the other domains tested (self-esteem, family and peer relationships, school/vocational performance, etc), no noticeable differences were found between the subjects and comparable populations. There was no significant association between psychosocial outcome and demographic features or clinical data. Our results suggest that patients who underwent SCT in their childhood or adolescence are at risk of developing long-term emotional or social problems. Due to the retrospective design of our study and the small sample size, no predictive factors for psychosocial distress could be identified.     

Immune recovery and immunotherapy after stem cell transplantation in children

Careful longitudinal studies of the lymphoid cell recovery after stem cell transplantation with other than HLA-identical sibling donors illustrated the prolonged T- and B-cellular immunodeficiency post-SCT, whereas NK-cell recovery was fast. Only low numbers of CD45RO memory T-cells, with a restricted TCR-repertoire, are present in the first 6 months post-SCT. The consequence is an increased risk of viral infections and possibly of leukemia relapse. The latter complication can be prevented by enhancing the anti-leukemic immune reactivity shortly after SCT. Different technical approaches were presented, the majority of them still being in the pre-clinical phase. NK-cell reactivity based on KIR-epitope mismatches between donor and recipient are promising for AML- and CML-, not for ALL-patients. The ALL-blasts may be killed by an antibody-dependent cellular cytotoxicity, using anti-CD19 antibodies, as was shown to be effective in vitro. Also the generation of leukemia-specific CTL's, making use of differences in minor histocompatibility antigens between donor and recipient, is now operational and may be a highly effective approach in a number of leukemic graft recipients.     

Reduction of GVHD and enhanced antitumor effects after adoptive infusion of alloreactive Ly49-mismatched NK cells from MHC-matched donors

We investigated if an infusion of alloreactive natural killer (NK) cells would reduce GVHD and mediate antitumor effects in mice undergoing MHC-matched allogeneic stem cell transplantation (SCT). Balb/c mice bearing RENCA tumors underwent an allogeneic SCT from MHC-matched B10.d2 donors and were given a single infusion of either Ly49 ligand-matched, ligand-mismatched, or no donor NK cells. Recipients of Ly49 ligand-mismatched NK cells had a reduced incidence of graft-versus-host disease (GVHD; 39% vs 100%; P < .01), and prolonged survival (median 84 days vs 39 days; P < .01) compared with SCT recipients not receiving NK cells. Recipients of Ly49 ligand-matched NK cells had the same incidence of GVHD and similar survival compared with controls not receiving NK cells. Pulmonary tumor burden was significantly (P < .01) lower in recipients that received Ly49-mismatched or Ly49-matched NK cells compared with recipients not receiving NK cells. These data provide in vivo evidence that a single infusion of alloreactive donor NK cells reduces GVHD and mediates antitumor effects following MHC-matched allogeneic transplantation.     

Preoperative and post‐operative psychosocial interventions for bariatric surgery patients: A systematic review

Psychosocial interventions are increasingly being utilized to help patients prepare for, and adjust to changes following, bariatric surgery in order to optimize psychosocial adjustment and weight loss. The current systematic review examined the impact of preoperative and post‐operative psychosocial interventions with a behavioural and/or cognitive focus on weight, dietary behaviours, eating pathology, lifestyle behaviours, and psychological functioning. A PsycINFO and Medline search of publications was conducted in March 2019. Two authors assessed retrieved titles and abstracts to determine topic relevance and rated the quality of included studies using a validated checklist. Forty‐four articles (representing 36 studies) met the study inclusion criteria. The current evidence is strongest for the impact of psychosocial interventions, particularly cognitive behavioural therapy, on eating behaviours (eg, binge eating and emotional eating) and psychological functioning (eg, quality of life, depression, and anxiety). The evidence for the impact of psychosocial interventions on weight loss, dietary behaviours (eg, dietary intake), and lifestyle behaviours (eg, physical activity) is relatively weak and mixed. Psychosocial interventions can improve eating pathology and psychosocial functioning among bariatric patients, and the optimal time to initiate treatment appears to be early in the post‐operative period before significant problematic eating behaviours and weight regain occur.     

Temporal trajectory of quality of life and its predictors in recipients of hematopoietic stem cell transplantation

This prospective longitudinal study evaluated the temporal trajectory of health-related quality of life (HRQOL) and its associated factors in patients who received hematopoietic stem cell transplantation (SCT) 6 months after transplantation. Eighty-nine adult patients who were admitted to Seoul National University Hospital for SCT were consecutively included in the study. The participants completed three standardized questionnaires: Insomnia Severity Index, Hospital Anxiety and Depression Scale, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. The participants completed the study questionnaires at three time points: before SCT (T1), immediately after SCT (T1), and 6 months after SCT (T3). Immediately after SCT, HRQOL decreased significantly (p?<?0.001), followed by recovery over 6 months. The conditioning regimen for SCT showed no correlation with HRQOL at T2 (p?=?0.283) or T3 (p?=?0.799), with no significant difference in HRQOL between allogeneic and autologous SCT recipients at T2 (p?=?0.829) or T3 (p?=?0.824). Depression (p?=?0.042), pain (p?=?0.023), and appetite loss (p?=?0.004) negatively influenced HRQOL at T1, whereas only pain (p?=?0.048) remained an important factor at T2. Six months after SCT, the two most frequent symptoms, fatigue and financial problems, became major factors (p?=?0.004 and p?=?0.005, respectively). Depression began to play an important role in HRQOL again at T3 (p?=?0.040). These findings demonstrate that SCT recipients need both psychological and medical support to achieve a better HRQOL after SCT.     

Differences in mothers' and fathers' health-related quality of life after pediatric SCT: a longitudinal study

The purpose of this study was to examine longitudinally health-related quality of life (HRQOL) and related factors in mothers and fathers of children who undergo SCT, before, and 1 and 2 years after SCT. A total of 84 parents (49 mothers/35 fathers) of patients diagnosed mainly with leukemia completed a HRQOL measure before SCT, 46 at 1 year (26 mothers/20 fathers) and 50 parents (31 mothers/19 fathers) at 2 years post SCT. Physical and psychosocial HRQOL summary scores are reported. Parents' age and gender, child's diagnosis, radiation history, age, behavior and physical health were examined. Linear mixed models for repeated measures with a covariate structure were used for analysis. Physical HRQOL did not differ between mothers and fathers or over time. Maternal and paternal psychosocial HRQOL scores improved by 2 years post SCT. Child's behavior problems and poor health, and maternal age (younger) predicted poor maternal psychosocial HRQOL 2 years post SCT. Child's behavior problems, diagnosis and treatment severity predicted poor paternal psychosocial HRQOL. These findings identify similar (child's poor behavior) and differential risk factors (parental young age, disease and treatment severity, and child's poor health status) for poor HRQOL for mothers and fathers. These findings can guide comprehensive family-care interventions before, during and after pediatric SCT.     

Allogeneic hematopoietic SCT in children with ALL: current concepts of ongoing prospective SCT trials

The definition of indications for allogeneic SCT in children with high-risk (HR) ALL in the first remission or after the first or subsequent relapse depends on biological features, response to treatment and survival after chemotherapy alone. As the results of frontline and relapse protocols are improving over time, there is a strong need for prospective SCT trials, ensuring a well-standardized procedure regarding all relevant components that are potentially responsible for heterogeneity in post-SCT outcome. Therefore, in 2003, the ALL-BFM and the ALL-REZ BFM Study Group initiated a prospective, international, multicenter trial (ALL-SCT-BFM 2003). This trial will now be extended to a larger consortium, trial ALL-SCT-BFM-international (ALL-SCT-BFMi). Strict rules define HLA-typing, donor selection, conditioning regimen, GvHD prophylaxis and therapy as well as standards of supportive care to reduce treatment-related mortality and establish an early GVL effect. Moreover, comprehensive and closely reviewed documentation and serious adverse event reporting shall ensure high study quality. Case-by-case discussions of any fatal or critical course during annual meetings will improve the culture of failure management and lead to modifications of guidelines of supportive care. Finally, the results of these prospective trials will determine the current potential of the different SCT procedures in HR or relapsed childhood ALL.     

Social support mediates the relationship between HIV stigma and depression/quality of life among people living with HIV in Beijing, China

Stigma towards people living with HIV is pervasive in China and related to poor service utilization, psychosocial distress and diminished quality of life (QOL). In an effort to identify mechanisms to reduce HIV stigma and its negative consequences, we examined whether social support mediates the relation between enacted stigma and both depressive symptoms and QOL among 120 HIV outpatients in Beijing, China. Generally, perceived social support was associated with less stigma, less depressive symptomatology and better QOL. Using multivariable regression models, we found that social support was a full mediator of the impact of stigma on both depressive symptomatology and QOL. The findings suggest social support may be an important target of interventions to reduce the impact of stigma on poor psychosocial health outcomes.     

Trends and predictors of quality of life among HIV-infected adults taking highly active antiretroviral therapy in rural Uganda

We examined trends and predictors of quality of life (QOL) over 12 months among a prospective cohort of 947 HIV-1-infected adults initiating highly active antiretroviral therapy (HAART) between May 2003 and May 2004 in rural Uganda. Participants provided clinical, demographic and psychosocial data at baseline and every three months thereafter. Outcome measures included physical and mental health summary scores based on the Medical Outcomes Study-HIV Health Survey (MOS-HIV). Generalised estimating equations were used to assess magnitude of change in summary scores and factors associated with QOL. Of 710 women and 237 men enrolled, the mean age was 38.7 years and mean baseline CD4 cell count was 124.1 cells/microL. At enrollment, physical and mental health summary scores were 39.2 and 40, respectively. By 12 months of HAART, scores increased by 11.2 points (p <0.001) and 7.4 points (p <0.001), respectively. For both scores, most gains were achieved by the third month of therapy. While several clinical, psychosocial and sociodemographic factors predicted QOL at HAART initiation, financial dependence on others was the only remaining predictor after controlling for time on HAART. Interventions to enhance the economic and employment opportunities of patients taking HAART in rural Africa may help maximise gains in QOL.     

The clinical features and outcome of 2009 H1N1 influenza infection in allo-SCT patients: a British Society of Blood and Marrow Transplantation study

The clinical course of 2009 H1N1 influenza in Allo-SCT patients is unknown. Data were collected in the UK from October 2009 to April 2010 on laboratory-confirmed cases of H1N1 influenza in Allo-SCT recipients. H1N1 infection was diagnosed in 60 patients, median age 42 years, at a median of 10 months post-SCT. Twenty-one patients (35%) developed pneumonia and nine (15%) required admission to intensive care units. Actuarial mortality was 7% at 28 days and 19% 4 months post-diagnosis of 2009 H1N1 influenza. Increasing age and pre-existing lung disease were risk factors for pneumonia (P=0.006 and 0.037, respectively); older age was a risk factor for death (P=0.012). Morbidity and mortality from 2009 H1N1 influenza in SCT patients exceeds that of immunocompetent patients, but parallels that in other critically ill hospitalised cohorts; the elderly and those with chronic pulmonary disease are at greatest risk.     

Early emergence of PNH-like T cells after allogeneic stem cell transplants utilising CAMPATH-1H for T cell depletion

CAMPATH-1H (C-1H) is widely used in vivo and / or in vitro for T cell depletion in hematopoietic SCT. This humanised monoclonal antibody is specific for CD52, a marker coexpressed on the majority of human lymphocytes with CD48 and other glycosylphosphatidyl-inositol (GPI) anchored proteins. We detected CD52 / CD48 dual expression on >99% of CD3(+) lymphocytes from normal individuals and all 15 post-SCT patients whose transplants did not utilise C-1H. By contrast, 23 / 26 patients with transplants involving C-1H (in vivo, in vitro or both) exhibited populations lacking CD52 expression that accounted for 49.7% (4.2-86.2%) of the CD3+ lymphocytes (median and range) in samples evaluated at a median of 2 months post-SCT. Most CD52- cells also lacked CD48 expression. These GPI- T cells were of either donor or mixed donor / recipient origin. They were predominant in the early months after SCT at times of profound lymphopenia and inversely correlated with the recovery of the absolute lymphocyte count (r= - 0.663, P<0.0001). The presence of CD52- cells has been correlated previously with clinical outcome after CAMPATH therapy for both malignant and nonmalignant diseases.     

Incidence and outcome of idiopathic pneumonia syndrome in pediatric stem cell transplant recipients

Idiopathic pneumonia syndrome (IPS) is a rare complication following stem cell transplant (SCT) and its incidence among pediatric SCT recipients is not known. To assess the incidence of IPS, we retrospectively reviewed the incidence of IPS at our center. IPS is defined as the presence of multilobar infiltrates by chest radiograph or computed tomography scan, need for supplemental oxygenation with declining pulse oximetry and no identifiable pulmonary infection. Between July 1999 and August 2005, 11 of 93 children who received a fully ablative allogeneic SCT (11.8%) developed IPS. All 11 patients had normal pulmonary evaluation before transplant. IPS developed at a median of 17 days (range 8-42 days) after transplant. Recipients of unrelated donor transplant had increased risk of developing IPS. There was a significant association between acute or hyperacute graft-versus-host disease (GVHD) and IPS (P=0.035). All patients had significant hypoxia and five patients required assisted ventilation. IPS was the cause of death in two patients. Although there was complete resolution of respiratory symptoms in the other nine patients, overall transplant-related mortality was significantly higher among patients with IPS (64 vs 17%, P=0.002). IPS is a relatively common complication in pediatric SCT recipients and acute GVHD is an important associated factor.     

Psychosocial supportive care for children receiving stem cell transplantation: practice patterns across centers

Although pediatric stem cell transplantation is associated with elevated risks for quality-of-life (QOL) deficits, morbidity, and late effects, little is known about how supportive care needs are addressed across different pediatric centers. This study examined practice patterns among centers enrolled in the Pediatric Blood and Marrow Transplant Consortium. In all, 65 centers (response rate=82.2%) were surveyed regarding QOL screening, psychosocial intervention services, and long-term follow-up care. Approximately 80% of centers provided routine screening for psychological difficulties and pain. A smaller number screened for fatigue (69.2%), cognitive deficits (52.3%), sleep difficulties (60.0%) or spiritual concerns (38.5%). Screening was conducted predominantly via interview; little use was made of standardized measures. Community-based centers screened some deficits more frequently than did academic ones (all P's相似文献   

Radiation exposure from diagnostic procedures following allogeneic stem cell transplantation – How much is acceptable?

Background

Frequent diagnostic radiology procedures in allogeneic stem cell transplantation (SCT) recipients raise concern about the potential harm from incidental radiation.

Objectives

To determine the cumulative radiation dose from diagnostic studies in allogeneic SCT and its impact on clinical outcome.

Patients and methods

This retrospective cohort study was conducted to determine the cumulative radiation dose from diagnostic studies following SCT. Sixty-four consecutive patients with hematological malignancies in a single tertiary care institution underwent total body irradiation (TBI)-based myeloablative conditioning followed by six of six human leukocyte antigen (HLA)-identical sibling allogeneic SCT. The median follow-up was 3 years. The cumulative effective dose in mSv from diagnostic radiological studies in the peri-transplant period from day ?30 to day +200 was calculated for each patient and its impact on overall survival and non-relapse mortality was determined.

Results

The median cumulative radiation exposure from diagnostic radiological procedures was 92 mSv (range 1.2–300), representing about 30× the normal annual background radiation for the population and 10% of the 1200 cGy TBI dose used in conditioning. Sixty-five percent of the cumulative radiation exposure was delivered between day +1 and day 100 and computed tomography scans contributed 88%. In multivariate analysis, diagnostic procedures did not significantly impact clinical outcomes.

Conclusions

While radiation exposure from diagnostic procedures did not impact clinical outcomes the risk of secondary cancers in long-term survivors is likely to be increased. Our results indicate that patients who are acutely ill for prolonged periods can receive clinically significant radiation doses during their hospital care. Our findings should prompt attempts to limit radiation exposure from diagnostic procedures in post-SCT recipients     

Quality of life in pediatric patients with implantable cardioverter defibrillators

Psychosocial and quality-of-life (QOL) outcomes in adult patients with implantable cardioverter-defibrillators (ICDs) are well studied. Minimal research exists regarding pediatric adjustment, despite a potentially more challenging adjustment process. The purpose of the present study was to examine psychosocial and QOL functioning of pediatric ICD patients from patient and parent self-reports. Children and primary caregiver dyads from several university hospitals were analyzed using the PedsQL, the Device Severity Index, the ICD and Avoidance Survey, and demographic information. Sixty children (25 female, 35 male) were enrolled. The present pediatric sample reported lower psychosocial and physical QOL scores than healthy children's normative scores. In comparison with a sample of chronically ill children, pediatric ICD patients reported lower physical QOL. Parent-observed QOL reports revealed lower psychosocial and physical QOL than parent-observed healthy norms and lower psychosocial and physical QOL than chronically ill norms. There were no QOL differences by ICD shocks or medical severity. Female patients reported lower psychosocial, physical, and cardiac QOL scores. Children reported better QOL than parent observations on psychosocial and physical health. Finally, 84.7% of children reported avoidance behaviors since ICD implantation, with female children avoiding places more than male children. In conclusion, pediatric ICD patients are comparable to children with other chronic illnesses with the exception of lower physical QOL. Similar to adult samples, female children reported poorer QOL and were more likely to engage in avoidance behaviors. Patients indicated better QOL perceptions than their parents' reports. ICD discharges and medical severity did not negatively affect QOL.     

Predictors of health-related quality of life in patients treated with auto- and allo-SCT for hematological malignancies

Identifying factors that predict health-related quality of life (QOL) following hematopoietic SCT, is important in estimating patients' abilities to adjust to the consequences of their disease and treatment. As the studies that have been published on this subject are scattered, the present study aimed to systematically review prognostic factors for health-related QOL after auto- and allo-SCT in hematological malignancies. A systematic, computerized search in Medline, EMBASE, PsycINFO and the Cochrane Library was conducted from 2002 to June 2010. The methodological quality of the studies was assessed using an adaptation of Hayden's criteria list. Qualitative data synthesis was performed to determine the strength of the scientific evidence. In all, 35 studies fulfilled the selection criteria. Strong-moderate evidence was found for GVHD, conditioning regimen, being female, younger age, receiving less social support and pre-transplant psychological distress as predictors of various aspects of health-related QOL following hematopoietic SCT. The results of this review may help transplant teams in selecting patients at risk for experiencing a diminished health-related QOL following hematopoietic SCT. Follow-up treatment can be provided in order to promote QOL.     

The effect of complete decongestive therapy on the quality of life of patients with peripheral lymphedema

Lymphedema is a chronic disorder which can adversely affect quality of life (QOL). The purpose of this study was 1) to evaluate whether QOL was improved in patients with lymphedema following Complete Decongestive Therapy (CDT), and 2) whether limb volume change as a result of treatment correlated with change in QOL. Thirty-six patients with peripheral lymphedema from varying causes were enrolled in the study. The QOL of each participant, with regard to physical, functional, and psychosocial concerns, was measured by pre- and post-treatment questionnaires. Percent edema volume reduction was calculated for each patient with only one affected limb. QOL pre- and post-treatment scores were assessed by multivariate repeated measures analysis. QOL scores differed significantly (p<0.05) between pre- and posttreatment in all areas of inquiry. Patients with lower extremity lymphedema had significantly greater mean improvement in QOL scores compared with patients with upper extremity lymphedema (p=0.02). There was no correlation between percent edema volume reduction and post-treatment QOL improvement. This study suggests that significant improvements are made in the QOL of patients exhibiting peripheral lymphedema following CDT, which is not necessarily correlated with limb volume reduction.
