RESUMEN

BACKGROUND: Some traditional Chinese medicine (TCM)-based integrated health interventions have been used for depression, but pooled efficacy remains unknown. AIMS AND OBJECTIVES: This study aimed to systematically evaluate the efficacy of TCM-based integrated health interventions for relieving depression. DESIGN: Systematic review and meta-analysis. METHODS: A comprehensive literature search was conducted on 17 databases from inception up to June 2022. Randomised controlled trials (RCTs) that examined an integrated health intervention based on TCM theory for depression were included. The risk of bias was assessed using the second version of the Cochrane risk-of-bias tool for randomised trials, and the quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluation system. RESULTS: Eighteen RCTs with a total of 1448 depressed participants were included. Health care providers, mainly nurses (14 studies), implemented TCM-based integrated health interventions. The pooled results showed that TCM-based integrated health interventions had larger effects on reducing depressive symptoms (15 studies; standardised mean difference = -2.05; 95% CI: -2.74, -1.37; p < .00001) compared with usual care at posttreatment but showed no significant difference contrasted to cognitive behavioural therapy (two studies, p = .31). However, the overall evidence was low. CONCLUSIONS: The meta-analysis results indicated that TCM-based integrated health interventions were effective in reducing depression. However, the results should be interpreted with caution because of the low quality of the included studies. Future RCTs with rigorous designs should be conducted to provide robust evidence of the efficacy of TCM-based integrated health interventions in treating depression. RELEVANCE TO CLINICAL PRACTICE: TCM-based integrated health interventions might be a potentially effective alternative for depression. Nurses could play an important role in designing and providing TCM-based integrated nursing interventions for patients with depression. NO PATIENT OR PUBLIC CONTRIBUTION: This is a systematic review and meta-analysis based on data from previous studies.

RESUMEN

BACKGROUND: Breast cancer survivors (BCS), particularly Latina BCS, experience weight gain and reduced physical activity (PA) post-treatment increasing the risk for recurrence. There is a lack of evidence on the intensity and type of PA needed to engage cultural subgroups and improve clinical outcomes. This study developed and piloted two non-traditional PA interventions among a diverse sample of BCS. METHODS: Twenty BCS (65% Latina; age 25-75) participated in a 2-arm parallel group-randomized pilot study to test the effects of an 8-week Latin dance and Qigong/Tai Chi intervention on PA and body composition. A seven-day pedometer protocol was used to measure steps/week and a bioelectric impedence scale was used to assess BMI and %body fat. T-tests were used to examine preliminary outcomes across both interventions and within intervention arms. RESULTS: There were no significant changes in steps/week, BMI, or %body fat across or in each separate intervention. A small effect size for increase in steps/day was found among participants in the Qigong/Tai Chi arm (0.10) and low-to-moderate effect sizes for reductions in % body fat overall (0.36), and separately for participants in Latin dance (0.26) and Qigong/Tai Chi (0.46). CONCLUSION: Latin dance and Qigong/Tai Chi are engaging and acceptable PA modalities that are promising for improving PA and body fat among diverse, high-risk BCS. Our findings highlight the need to continue to reach and engage high-risk BCS, including Latina survivors, using novel, culturally-sensitive PA interventions. Future studies should extend and more rigorously test these novel approaches to improving outcomes associated with recurrence.

RESUMEN

OBJECTIVE: To assess the effectiveness of physical activity interventions in improving objective and patient-reported outcomes in HNC survivors. INTRODUCTION: Multiple guidelines recommend that head and neck cancer (HNC) survivors participate in regular physical activity. Physical activity is associated with improved outcomes and mortality in healthy individuals as well as in certain cancer populations. However, the effectiveness of physical activity interventions in HNC survivors is inadequately understood. METHODS AND RESULTS: Our literature search through December 2018 identified 2,392 articles. After de-duplication, title and abstract review, full-text review and bibliographic search, 20 studies met all inclusion criteria. Inclusion criteria included any full-body physical activity intervention in HNC survivors that did not target discrete organ sites or functions (e.g. swallowing). Study cohorts included 749 predominantly male participants with a mean age range of 48-63 years. At their conclusion, physical activity interventions were associated with at least one significant improvement in an objective or patient-reported outcome in 75% of studies. Aerobic capacity and fatigue were the most commonly improved outcomes. None of the included studies evaluated associations with survival or recurrence. Although traditional aerobic and resistance interventions were more common, a greater proportion of alternative physical activity (yoga and Tai Chi) interventions demonstrated improved objective and patient-reported outcomes. CONCLUSION: Physical activity interventions in HNC survivors often conferred some improvement in objective and patient-reported outcomes. Additional highly-powered, randomized controlled studies are needed to establish the optimal type, intensity, and timing of physical activity interventions as well as their impact on oncologic outcomes.

RESUMEN

Although reliable strategies exist to promote healthy habits that reduce childhood obesity, the sustainability of these strategies remains an ongoing public health challenge. This study aimed to identify factors experienced in a large, multisite project aimed at reducing childhood obesity that might contribute to project sustainability. Hypothesized constructs underpinning sustainability included replicability, continuation of benefits, institutionalization, and community capacity. Key informants (n = 27) completed 60 min, in-depth interviews, which were audio recorded and transcribed. Transcripts were first coded using a combined deductive and inductive approach. Four major themes emerged (with numerous subthemes): developing partnerships, challenges to the sustainability of implemented programming, the importance of intervening in multiple settings, and ongoing implementation and evaluation strategies. Replicability of complex childhood obesity interventions is possible when there are strong partnerships. Benefits can continue to be conferred from programming, particularly when evidence-based strategies are used that employ best practices. Implementation is facilitated by institutionalization and policies that buffer challenges, such as staffing or leadership changes. Community capacity both enhances the sustainability of interventions and develops as a result of strengthening partnerships and policies that support childhood obesity programming.

RESUMEN

Age-related macular degeneration (AMD) is a leading cause of irreversible vision loss among the elderly population. Genetic studies in susceptible individuals have linked this ocular disease to deregulated complement activity that culminates in increased C3 turnover, retinal inflammation and photoreceptor loss. Therapeutic targeting of C3 has therefore emerged as a promising strategy for broadly intercepting the detrimental proinflammatory consequences of complement activation in the retinal tissue. In this regard, a PEGylated second-generation derivative of the compstatin family of C3-targeted inhibitors is currently in late-stage clinical development as a treatment option for geographic atrophy, an advanced form of AMD which lacks approved therapy. While efficacy has been strongly suggested in phase 2 clinical trials, crucial aspects still remain to be defined with regard to the ocular bioavailability, tissue distribution and residence, and dosing frequency of such inhibitors in AMD patients. Here we report the intraocular distribution and pharmacokinetic profile of the fourth-generation compstatin analog, Cp40-KKK in cynomolgus monkeys following a single intravitreal injection. Using a sensitive surface plasmon resonance (SPR)-based competition assay and ELISA, we have quantified both the amount of inhibitor and the concentration of C3 retained in the vitreous of Cp40-KKK-injected animals. Cp40-KKK displays prolonged intraocular residence, being detected at C3-saturating levels for over 3 months after a single intravitreal injection. Moreover, we have probed the distribution of Cp40-KKK within the ocular tissue by means of immunohistochemistry and highly specific anti-Cp40-KKK antibodies. Both C3 and Cp40-KKK were detected in the retinal tissue of inhibitor-injected animals, with prominent co-localization in the choroid one-month post intravitreal injection. These results attest to the high retinal tissue penetrance and target-driven distribution of Cp40-KKK. Given its subnanomolar binding affinity and prolonged ocular residence, Cp40-KKK constitutes a promising drug candidate for ocular pathologies underpinned by deregulated C3 activation.

RESUMEN

Purpose: To investigate relationships among physical activity, changes in physical function, and health-related quality of life (HRQOL) among patients with pancreatic adenocarcinoma enrolled in a home-based exercise prehabilitation program. Methods: Patients with resectable pancreatic adenocarcinoma receiving preoperative chemotherapy and/or chemoradiation were enrolled on this prospective, single-arm trial and were advised to perform ≥60 minutes each of moderate-intensity aerobic exercise and strengthening exercise weekly. Activity was measured via self-report and accelerometers, including moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and sedentary activity (SA). Physical function measures at baseline and restaging follow-up included 6-minute walk test (6MWT), 5 times sit-to-stand (5×STS), handgrip strength (HGS), 3-m walk for gait speed (GS), and the PROMIS Physical Function Short Form. HRQOL was measured via the FACT-Hep questionnaire. Results: Fifty participants with mean age 66 years (standard deviation = 8 years) were enrolled. The 6MWT, 5×STS, and GS significantly improved from baseline to restaging follow-up (P=.001, P=.049, and P=.009, respectively). Increases in self-reported aerobic exercise, weekly MVPA, and LPA were associated with improvement in 6MWT (ß=.19, P=.048; ß=.18, P=.03; and ß=.08, P=.03, respectively) and self-reported physical functioning (ß=.02, P=.03; ß=.03, P=.005; and ß=.01, P=.02, respectively). Increased weekly LPA was associated with increased HRQOL (ß=.03, P=.02). Increased SA was associated with decreased HRQOL (ß=-.02,P=.01). Conclusions: Patients with potentially resectable pancreatic cancer exhibit meaningful improvement in physical function with prehabilitation; physical activity was associated with improved physical function and HRQOL. These data highlight the importance of physical activity during treatment for pancreatic cancer.

RESUMEN

Objective: Pilot test GoWoman, a small-group weight management intervention for mobility impaired women that was a disability- and gender-responsive adaptation of the Diabetes Prevention Program delivered in the online virtual world of Second Life®. Objectives were to (1) examine pre-/post-intervention differences in weight, waist circumference, diet, physical activity, self-efficacy for diet and physical activity, nutrition knowledge and social support for weight management, (2) determine intervention feasibility (fidelity, attrition, engagement, acceptability). Design: Single-group modified interrupted time series quasi-experimental design whereby participants served as their own controls. Results: Thirteen women attended ≥8 of 16 GoWoman weekly sessions and lost an average of 5.97 pounds (2.71 kg) (3.31%) body weight (Cohen's d = 0.74) and 1.44 inches (3.66 cm) (3.58%) waist circumference (Cohen's d = 0.83). There were significant improvements in physical activity, diet and self-efficacy for diet and physical activity. All benchmarks for feasibility were met. Ratings of intervention content, group interactions and support and virtual world experiences were highly positive. Conclusion: Findings suggest that a disability- and gender-responsive weight management intervention with peer group support delivered in an online virtual world is feasible, meaningful and may assist with weight management for mobility impaired women. Implications for Rehabilitation This study addresses a gap in the general and rehabilitation research literature by addressing the disproportionately high rates of obesity among women with mobility impairments, who are generally excluded from tests of weight management interventions if they have limited ability to engage in vigorous physical activity. The GoWoman program is an adaptation of the Diabetes Prevention Program Lifestyle Change curriculum that is tailored to meet the unique weight management needs of women with mobility impairments, and was created to become a publicly available, disability- and gender-responsive intervention that can be used in community and rehabilitation settings. More rehabilitation and health promotion program should be offered in the free, online, virtual world of Second Life® since participants in this pilot study offered many favorable comments about the new learning and social opportunities available to them there and they did not have to deal with the disability-related environmental and health challenges that often prevent them from participating in face-to-face workshops. Preliminary indications of improvements in body weight, waist circumference, diet and physical activity after attending the GoWoman weight management intervention offered in Second Life® tell us that these strategies are feasible for helping women with mobility impairments manage their weight and should undergo further testing.

RESUMEN

The purpose of this integrative review was to analyze the state of science concerning the influence of parenting practices on children's physical activity (PA) levels. A total of 38 studies met the inclusion criteria after full-text review. The body of research is limited in experimental designs with only three studies measuring the influence of the intervention on parenting practices. Seven of the 30 quantitative studies (23.3%) found significant associations between parental role modeling of PA and children's PA levels. Seven of the eight (87.5%) qualitative studies identified parental role modeling of PA as important in promoting children's PA. Sixteen of the 30 (53.3%) quantitative studies found that parental support of PA was significantly associated with children's PA. Five of the eight (62.5%) qualitative studies identified logistic support as supporting PA in children. The science could be expanded by the development of randomized controlled trials aimed at this area.

RESUMEN

Culturally appropriate, innovative strategies to increase physical activity (PA) in women of color are needed. This study examined whether participation in SALSA, an 8-week randomized, crossover pilot study to promote PA, led to improved psychosocial outcomes and whether these changes were associated with changes in PA over time. Women of color (N = 50) completed Internet-based questionnaires on PA, exercise self-efficacy, motivational readiness, stress, and social support at three time points. Women reported high socioeconomic status, decreases in exercise self-efficacy, and increases in motivational readiness for exercise and a number of stressful events (p < .05); changes in motivational readiness for exercise varied by group (p = .043). Changes in psychosocial factors were associated with increases in PA. Latin dance improved motivational readiness for PA. Future studies are needed to determine whether Latin dance improves other psychological measures and quality of life in women of color in an effort to increase PA and reduce health disparities.

RESUMEN

ß-Elemene is a new anticancer compound extracted from the Chinese medicinal herb Rhizoma zedoariae. We have shown previously that ß-elemene increases cisplatin cytotoxicity and enhances cisplatin sensitivity via blocking cell cycle progression at G2/M phase in resistant ovarian tumor cells. In the current study, we asked whether ß-elemene-augmented cisplatin activity in ovarian carcinoma cells is mediated through the induction of apoptosis. Here, we show that ß-elemene triggered apoptotic cell death in chemoresistant human ovarian cancer A2780/CP and MCAS cells in a dose- and time-dependent fashion, as assessed by six different apoptosis assays. Intriguingly, ß-elemene was a stronger inducer of apoptosis than cisplatin in this model system, and a synergistic effect on induction of cell death was observed when the tumor cells were treated with both agents. Furthermore, ß-elemene plus cisplatin exposure significantly disrupted the mitochondrial transmembrane potential (ΔΨ (m)) and increased the release of cytochrome c from mitochondria into the cytoplasm. The combination treatment with both compounds also induced increases in caspase-3/8/9 activities and caspase-9 cleavage, enhanced protein expression of Bax and phosphorylation of Bcl-2 at Ser-70, and reduced the protein levels of Bcl-2 and Bcl-X(L) in the platinum-resistant ovarian cancer cells. Taken together, these data indicate that ß-elemene sensitizes chemoresistant ovarian carcinoma cells to cisplatin-induced apoptosis and that the augmented effect of ß-elemene on cisplatin cytotoxicity and sensitivity in resistant ovarian tumor cells is mediated through a mitochondria- and caspase-dependent cell death pathway.

RESUMEN

BACKGROUND Stroke is the major cause of adult disability. Selective serotonin reuptake inhibitors (SSRIs) have been used for many years to manage depression. Recently, small trials have demonstrated that SSRIs might improve recovery after stroke, even in people who are not depressed. Systematic reviews and meta-analyses are the least biased way to bring together data from several trials. Given the promising effect of SSRIs on stroke recovery seen in small trials, a systematic review and meta-analysis is needed. OBJECTIVE To determine whether SSRIs improve recovery after stroke, and whether treatment with SSRIs was associated with adverse effects. METHODS Search methods: We searched the Cochrane Stroke Group Trials Register (August 2011), Cochrane Depression Anxiety and Neurosis Group Trials Register (November 2011), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 8), MEDLINE (from 1948 to August 2011), EMBASE (from 1980 to August 2011), CINAHL (from 1982 to August 2011), AMED (Allied and Complementary Medicine) (from 1985 to August 2011), PsycINFO (from 1967 to August 2011) and PsycBITE (Pyschological Database for Brain Impairment Treatment Efficacy) (March 2012). To identify further published, unpublished and ongoing trials we searched trials registers, pharmaceutical websites, reference lists, contacted experts and performed citation tracking of included studies. Selection criteria: We included randomized controlled trials that recruited stroke survivors (ischaemic or haemorrhagic) at any time within the first year. The intervention was any SSRI, given at any dose, for any period. We excluded drugs with mixed pharmacological effects. The comparator was usual care or placebo. In order to be included, trials had to collect data on at least one of our primary (dependence and disability) or secondary (impairments, depression, ...

RESUMEN

BACKGROUND: Stroke is the major cause of adult disability. Selective serotonin reuptake inhibitors (SSRIs) have been used for many years to manage depression. Recently, small trials have demonstrated that SSRIs might improve recovery after stroke, even in people who are not depressed. Systematic reviews and meta-analyses are the least biased way to bring together data from several trials. Given the promising effect of SSRIs on stroke recovery seen in small trials, a systematic review and meta-analysis is needed. OBJECTIVES: To determine whether SSRIs improve recovery after stroke, and whether treatment with SSRIs was associated with adverse effects. SEARCH METHODS: We searched the Cochrane Stroke Group Trials Register (August 2011), Cochrane Depression Anxiety and Neurosis Group Trials Register (November 2011), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 8), MEDLINE (from 1948 to August 2011), EMBASE (from 1980 to August 2011), CINAHL (from 1982 to August 2011), AMED (Allied and Complementary Medicine) (from 1985 to August 2011), PsycINFO (from 1967 to August 2011) and PsycBITE (Pyschological Database for Brain Impairment Treatment Efficacy) (March 2012). To identify further published, unpublished and ongoing trials we searched trials registers, pharmaceutical websites, reference lists, contacted experts and performed citation tracking of included studies. SELECTION CRITERIA: We included randomised controlled trials that recruited stroke survivors (ischaemic or haemorrhagic) at any time within the first year. The intervention was any SSRI, given at any dose, for any period. We excluded drugs with mixed pharmacological effects. The comparator was usual care or placebo. In order to be included, trials had to collect data on at least one of our primary (dependence and disability) or secondary (impairments, depression, anxiety, quality of life, fatigue, healthcare cost, death, adverse events and leaving the trial early) outcomes. DATA COLLECTION AND ANALYSIS: We extracted data on demographics, type of stroke, time since stroke, our primary and secondary outcomes, and sources of bias. For trials in English, two review authors independently extracted data. For Chinese papers, one review author extracted data. We used standardised mean differences (SMD) to estimate treatment effects for continuous variables, and risk ratios (RR) for dichotomous effects, with their 95% confidence intervals (CIs). MAIN RESULTS: We identified 56 completed trials of SSRI versus control, of which 52 trials (4059 participants) provided data for meta-analysis. There were statistically significant benefits of SSRI on both of the primary outcomes: RR for reducing dependency at the end of treatment was 0.81 (95% CI 0.68 to 0.97) based on one trial, and for disability score, the SMD was 0.91 (95% CI 0.60 to 1.22) (22 trials involving 1343 participants) with high heterogeneity between trials (I(2) = 87%; P < 0.0001). For neurological deficit, depression and anxiety, there were statistically significant benefits of SSRIs. For neurological deficit score, the SMD was -1.00 (95% CI -1.26 to -0.75) (29 trials involving 2011 participants) with high heterogeneity between trials (I(2) = 86%; P < 0.00001). For dichotomous depression scores, the RR was 0.43 (95% CI 0.24 to 0.77) (eight trials involving 771 participants) with high heterogeneity between trials (I(2) = 77%; P < 0.0001). For continuous depression scores, the SMD was -1.91 (95% CI -2.34 to -1.48) (39 trials involving 2728 participants) with high heterogeneity between trials (I(2) = 95%; P < 0.00001). For anxiety, the SMD was -0.77 (95% CI -1.52 to -0.02) (eight trials involving 413 participants) with high heterogeneity between trials (I(2) = 92%; P < 0.00001). There was no statistically significant benefit of SSRI on cognition, death, motor deficits and leaving the trial early. For cognition, the SMD was 0.32 (95% CI -0.23 to 0.86), (seven trials involving 425 participants) with high heterogeneity between trials (I(2) = 86%; P < 0.00001). The RR for death was 0.76 (95% CI 0.34 to 1.70) (46 trials involving 3344 participants) with no heterogeneity between trials (I(2) = 0%; P = 0.85). For motor deficits, the SMD was -0.33 (95% CI -1.22 to 0.56) (two trials involving 145 participants). The RR for leaving the trial early was 1.02 (95% CI 0.86 to 1.21) in favour of control, with no heterogeneity between trials. There was a non-significant excess of seizures (RR 2.67; 95% CI 0.61 to 11.63) (seven trials involving 444 participants), a non-significant excess of gastrointestinal side effects (RR 1.90; 95% CI 0.94 to 3.85) (14 trials involving 902 participants) and a non-significant excess of bleeding (RR 1.63; 95% CI 0.20 to 13.05) (two trials involving 249 participants) in those allocated SSRIs. Data were not available on quality of life, fatigue or healthcare costs.There was no clear evidence from subgroup analyses that one SSRI was consistently superior to another, or that time since stroke or depression at baseline had a major influence on effect sizes. Sensitivity analyses suggested that effect sizes were smaller when we excluded trials at high or unclear risk of bias.Only eight trials provided data on outcomes after treatment had been completed; the effect sizes were generally in favour of SSRIs but CIs were wide. AUTHORS' CONCLUSIONS: SSRIs appeared to improve dependence, disability, neurological impairment, anxiety and depression after stroke, but there was heterogeneity between trials and methodological limitations in a substantial proportion of the trials. Large, well-designed trials are now needed to determine whether SSRIs should be given routinely to patients with stroke.

RESUMEN

OBJECTIVES: The aim of the study was to explore experiences of practising mindfulness in participants within an early intervention for psychosis (EIP) service. DESIGN: A qualitative research methodology was used - that of grounded theory. This was chosen as it enabled examination of clients' experiences of mindfulness practice. METHODS: The experience of mindfulness among nine people within an EIP service who had been practising mindfulness for at least 20 weeks was investigated. Semi-structured interviews exploring how mindfulness practice related to psychosis and day-to-day life were recorded verbatim, transcribed, and analysed. RESULTS: Four main categories emerged: being able to use mindfulness, making sense of mindfulness and coping, relating to people differently, and increased self-understanding and acceptance. CONCLUSIONS: All participants reported subjective benefits and challenges of mindfulness practice, and gave insights into processes of change. These preliminary data suggest mindfulness can be of use to individuals experiencing their first episode of psychosis.

RESUMEN

African American (AA) and Hispanic or Latina (HL) women have the highest rates of overweight and obesity of any gender and ethnic groups. Binge eating disorder (BED) is the most common eating disorder in the United States and is linked to overweight and obesity. Traditional treatments for BED may not be appropriate or viable for AA and HL women, because they are less likely than whites to seek treatment for psychological conditions and may have less access to healthcare. Improving dietary habits in those with BED or subthreshold BED may reduce binge eating symptoms. The current study investigated the association of fruit, vegetable, and fat consumption to binge eating symptoms in AA and HL women. AA and HL women in the Health Is Power (HIP) study (N=283) reported fruit and vegetable intake, fat intake, and binge eating symptoms. Women were middle aged (M=45.8 years, SD=9.2) and obese (M BMI=34.5 kg/m(2), SD=7.5). Greater fat consumption was correlated with lower fruit and vegetable consumption (r(s)=-0.159, p<0.01). Higher BMI (r(s)=0.209, p<0.01), and greater fat consumption (r(s)=0.227, p<0.05) were correlated with increased binge eating symptoms. Multiple regression analysis demonstrated that for HL women (ß=0.130, p=0.024), higher BMI (ß=0.148, p=0.012), and greater fat consumption (ß=0.196, p=0.001) were associated with increased binge eating symptoms (R(2)=0.086, F(3,278)=8.715, p<0.001). Findings suggest there may be a relationship between fat consumption and binge eating symptoms, warranting further study to determine whether improving dietary habits may serve as a treatment for BED in AA and HL women.

RESUMEN

We previously showed that polyphyllin D (PD) produced a stronger apoptotic effect in R-HepG2 with multi-drug resistance (MDR) than that in its parent HepG2 cells without MDR. In this study, PD was found to elicit mitochondrial fragmentation in live cells by using total internal reflection fluorescence microscopy (TIRFM). When mitochondria were isolated and treated directly with PD, a stronger swelling, deeper transmembrane depolarization, and more apoptosis-inducing factor (AIF) release were observed from the mitochondria of R-HepG2 than that of HepG2. These observations suggest that PD is a potent anti-cancer agent that bypasses MDR and elicits apoptosis via mitochondrial injury.
