目的探讨双心诊疗模式对急性冠脉综合征(ACS)患者血脂控制的影响。方法选取100例ACS患者,随机分为双心诊疗模式组(双心组)和对照组各50例。两组患者均给予常规治疗。双心组同时接受心理干预。于入院前、1月、3月,采用汉密尔顿焦虑量表17项(HAMA-17)和汉密尔顿抑郁量表(HAMD)评定两组患者焦虑和抑郁状况,同时检测总胆固醇(CHOL)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)。结果①入院前,两组HAMD-17和HAMA评分比较差异无统计学意义(P0.05),3月后对照组评分[(22.56±4.99),(22.81±3.93)]较入院前、1月时高,双心组评分[(11.60±4.95),(12.44±4.13)]较入院前低,双心组评分下降更为明显(P0.05)。②入院1月、3月后,两组CHOL,LDL-C水平均较入院前降低(P0.05),且双心组低于对照组(P0.05)。结论双心诊疗模式可以改善ACS患者的心理状况,可能更有助于控制血脂。     

An examination of the psychometric properties of the Hospital Anxiety and Depression Scale in Chinese patients with acute coronary syndrome

The psychometric properties of the Hospital Anxiety and Depression Scale (HADS) as a screening instrument for patients with acute coronary syndrome (ACS) were investigated in a translated Chinese version of the instrument. A confirmatory factor analysis (CFA) was conducted on the HADS to establish its psychometric properties in 138 ACS patients over two observation points (within 1 week and 6 months post-admission for ACS). Internal and test–retest reliability values for the HADS total and HADS anxiety sub-scales were found to be acceptable. The HADS depression sub-scale lacked acceptable internal reliability. The underlying factor structure of the HADS comprised three distinct factors, though inconsistency between the best three-factor model fit was observed between observation points. The HADS was confirmed to be a useful screening instrument to assess symptoms of psychological distress in ACS patients. Further research is required to determine the most appropriate use of HADS sub-scale structures in clinical populations.     

The puzzle of depression and acute coronary syndrome: Reviewing the role of acute inflammation

The relationship between depression and coronary heart disease is well-established, but causal mechanisms are poorly understood. The aim of this review is to stimulate different ways of viewing the relationship between depression and adverse outcomes following acute coronary syndrome (ACS) and coronary artery bypass graft (CABG) surgery patients. We present an argument for depression in ACS and CABG patients being a qualitatively distinct form from that observed in psychiatric populations. This is based on three features: (1) depression developing after cardiac events has been linked in many studies to poorer outcomes than recurrent depression; (2) somatic symptoms of depression following cardiac events are particularly cardiotoxic; (3) depression following an ACS does not respond well to antidepressant treatments. We propose that inflammation is a common causal process responsible in part both for the development of depressive symptoms and for adverse cardiac outcomes, and we draw parallels with inflammation-induced sickness behaviour. Clinical implications of our observations are discussed along with suggestions for further work to advance the field.     

Specificity of depression following an acute coronary syndrome to an adverse outcome extends over five years

Many studies have demonstrated that depression is associated with a worse cardiovascular outcome and increased risk of death in those experiencing an acute coronary syndrome (ACS). Recent studies have suggested, however, that any association is strongly influenced by the timing of the depression, with post-ACS depression providing the greatest risk. Establishing any timing impact should assist etiological clarification. We initially recruited 489 subjects hospitalized for an ACS, assessed lifetime and current depression, and then - at 1 and 12 months - assessed subsequent depression. Subjects were followed for up to 5 years to assess cardiovascular outcome and the impact of depression at differing time points, with three defined poor outcome categories (i.e. cardiac admission and/or cardiac rehospitalization). While outcome was associated with a number of non-depression variables, a poor outcome was most clearly associated with depressive episodes emerging at the time of the ACS but with some risk affected by episodes that commenced prior to the ACS and being persistent. Neither lifetime depressive episodes nor transient depressive episodes occurring around the baseline ACS event appeared to provide any risk. Study findings indicate that any differential deleterious impact of post-ACS depression has both short-term and longer-term outcomes, and, by implicating the centrality of post-ACS depression, should assist studies seeking to identify causal explanations.     

Frequency and clinical correlates of bipolar features in acute coronary syndrome patients

BackgroundDepression and acute coronary syndrome (ACS) are both extremely prevalent diseases. Studies aimed at evaluating whether depression is an independent risk factor for cardiac events provided no definitive results. In most of these studies, depression has been broadly defined with no differentiation between unipolar (MDD) versus bipolar forms (BD). The aim of this study was to evaluate the frequency of DSM-IV BD (bipolar I and bipolar II subtypes, cyclothymia), as well as temperamental or isolated bipolar features in a sample of 171 patients hospitalized for ACS. We also explored whether these psychopathological conditions were associated with some clinical characteristics of ACS.MethodsPatients with ACS admitted to three neighboring Cardiac Intensive Care Units (CICUs) in a 12-month continuative period of time were eligible for inclusion if they met the criteria for either acute myocardial infarct with or without ST-segment elevation or unstable angina, verified by standard ACS criteria. All patients underwent standardized cardiological and psychopathological evaluations.ResultsOf the 171 ACS patients enrolled, 37 patients (21.7%) were found to have a DSM-IV mood disorder. Of these, 20 (11.7%) had bipolar type I or type II or cyclothymia, while 17 (10%) were the cases of MDD. Rapid mood switches ranged from 11% of ACS patients with no mood disorders, to 47% of those with MDD to 55% of those with BD. Linear regression analysis showed that a diagnosis of BD (p = .023), but not that of MDD (p = .721), was associated with a significant younger age at the index episode of ACS. A history of previous coronary events was more frequent in ACS patients with BD than in those with MDD.ConclusionsOur data indicate that bipolar features and diagnosis are frequent in ACS patients. Bipolar disorder has a negative impact on cardiac symptomatology. Further research in this area is warranted.     

Conservative treatment options for carpal tunnel syndrome: a systematic review of randomised controlled trials

Carpal tunnel syndrome (CTS) is a common disorder, for which various conservative treatment options are available. The objective of this study is to determine the efficacy of the various conservative treatment options for relieving the symptoms of CTS. Computer-aided searches of MEDLINE (1/1966 to 3/2000), EMBASE (1/1988 to 2/2000) and the Cochrane Controlled Trials Register (2000, issue 1) were conducted, together with reference checking. Included were randomised controlled trials evaluating the efficacy of conservative treatment options in a study population of CTS patients, with a full report published in English, German, French or Dutch. Two reviewers independently selected the studies. Fourteen randomised controlled trials were included in the review. Assessment of methodological quality and data-extraction was independently performed by two reviewers. A rating system, based on the number of studies and their methodological quality and findings, was used to determine the strength of the available evidence for the efficacy of the treatment. Diuretics, pyridoxine, non-steroidal anti-inflammatory drugs, yoga and laser-acupuncture seem to be ineffective in providing short-term symptom relief (varying levels of evidence) and steroid injections seem to be effective (limited evidence). There is conflicting evidence for the efficacy of ultrasound and oral steroids. For providing long-term relief from symptoms there is limited evidence that ultrasound is effective, and that splinting is less effective than surgery. In conclusion, there is still little known about the efficacy of most conservative treatment options for CTS. To establish stronger evidence more high quality trials are needed.

Traditional needle acupuncture treatment for insomnia: A systematic review of randomized controlled trials

ObjectivesPrevious reviews regarding traditional needle acupuncture (TNA) treatment for insomnia were limited to English scientific literature. A comprehensive review including Chinese and English literature has therefore been conducted to examine the efficacy of TNA for insomnia.MethodsWe performed systematic review of randomized controlled trials (RCTs) of TNA as intervention for insomnia against placebo, Western medication, and non-treated controls. The methodological quality of the studies was assessed by the modified Jadad score and the acupuncture procedure was appraised by the STRICTA criteria.ResultsTwenty RCTs were identified for detailed analysis. Majority of the RCTs concluded that TNA was significantly more effective than benzodiazepines for treating insomnia, with mean effective rates for acupuncture and benzodiazepines being 91% and 75%, respectively. In two more appropriately conducted trials, TNA appeared to be more efficacious in improving sleep than sleep hygiene counseling and sham acupuncture. Standardized and individualized acupuncture had similar effective rates. Despite these positive outcomes, there were methodological shortcomings in the studies reviewed, including imprecise diagnostic procedure, problems with randomization, blinding issues, and insufficient safety data. Hence, the superior efficacy of TNA over other treatments could not be ascertained.ConclusionSince the majority of evidence regarding TNA for insomnia is based on studies with poor-quality research designs, the data, while somewhat promising, do not allow a clear conclusion on the benefits of TNA for insomnia. Moreover, the results support the need for large scale placebo-controlled double-blinded trials.

Depressive symptoms in persons with acute coronary syndrome: Specific symptom scales and prognosis

Objective

To determine which particular depressive symptom scales, derived from three scales, predicted poorer prognosis in persons with acute coronary syndrome (ACS).

Methods

Hospitalized ACS patients (n=408) completed questionnaires (depression, vital exhaustion). Mokken scaling derived unidimensional scales. Major cardiac events (cardiac mortality, ACS, unplanned revascularization) were assessed at median 67 weeks post event.

Results

Only depressive symptoms of fatigue-sadness predicted prognosis in univariate (hazard ratio [HR]=1.8, 95% CI 1.1-3.0, P=.025) and multivariate analysis (HR=1.8, 95% CI 1.1-2.9, P=.025). Symptoms of anhedonia (HR=1.6, 95% CI 0.9-2.8, P=.102) and depressive cognitions (HR=1.3, 95% CI 0.7-2.2, P=.402) did not.

Conclusion

Symptoms of fatigue-sadness, but not other symptoms, were associated with increased risk of major cardiac events. Depression should be considered as a multidimensional, rather than a unidimensional, entity when designing interventions.     

Cortisol awakening response is elevated in acute coronary syndrome patients with type-D personality

OBJECTIVE: Type-D or "distressed" personality and depression following admission for acute coronary syndrome (ACS) have been associated with poor clinical outcome. The biological pathways underpinning this relationship may include disruption of the hypothalamic-pituitary-adrenocortical (HPA) axis. We therefore assessed cortisol output in patients who had recently suffered from ACS. METHOD: Salivary cortisol was assessed eight times over a 24-h period in 72 patients within 5 days of admission for ACS. Depressive symptoms were measured with the Beck Depression Inventory (BDI), and type-D personality was measured with the Type-D Scale-16. Particular attention was given to cortisol awakening response (CAR), which was measured as the difference in cortisol between waking and peak responses 15-30 min later. RESULTS: Cortisol showed a typical diurnal pattern, with low levels in the evening, high levels early in the day, and CAR averaging 7.58+/-10.0 nmol/l. Cortisol was not related to the severity of ACS or underlying coronary artery disease or to BDI scores. The CAR was positively associated with type-D personality independently of age, gender, and body mass (P=.007). Linear regression showed that type-D personality accounted for 7.9% of the variance in CAR after age, sex, body mass, BDI, cortisol level on waking, and fatigue had been taken into account (P=.008). CONCLUSIONS: Type-D personality may be associated with disruption of HPA axis function in survivors of acute cardiac events and may contribute to heightened inflammatory responses influencing future cardiac morbidity.     

Characterising acute coronary syndrome-associated depression: Let the data speak

Depression in the context of acute coronary syndrome (ACS) is understood to confer increased morbidity and mortality risk. The pathophysiological mechanisms underlying this association remain poorly understood, although several candidates including inflammation, cardiac autonomic dysregulation, and behavioural factors are viewed as of key importance. No single bio-behavioural explanatory model of ACS-associated depression has emerged, likely due the substantial heterogeneity across both conditions. We studied 344 patients with ACS; 45 fulfilled diagnostic (DSM-IV) criteria for a major depressive episode occurring within 1-month of ACS, and 13 had ongoing major depression that pre-dated ACS and continued through to 1 month post-ACS. We employed two statistical methods (multinomial logistic regression; and latent class analysis) and a range of immunological, autonomic and nutritional markers in an attempt to characterise a biological basis for ACS-associated depression. Regression modelling failed to accurately predict categorical group membership of ACS-associated depression. An alternative data-driven approach produced a three-class solution, with the derived classes differing on measure of C-reactive protein, vitamin D, omega-6:omega-3 ratio, heart rate variability, and age (all p ⩽ 0.004). The majority of participants with ACS-associated and ongoing depression were members of the class characterised by the greatest biological disturbance. Patients with depression differed from those without depression on a range of psychological trait and state variables; additionally reporting poorer sleep quality, higher levels of social isolation, and functional impairment, but had similar biological profiles. Patients with ongoing depression generally had higher scores on these psychological/behavioural measures. Our novel analytic approach identified a combination of biomarkers suggestive of a role for immune, autonomic, and nutritional pathways in the manifestation of depression during ACS, in the context of additional psychosocial and behavioural vulnerabilities. Further studies are required to confirm the causal role of these factors in perpetuating depression and increasing risk of poor-health outcomes.     

A systematic review of randomized trials for the treatment of burning mouth syndrome

ObjectivesBurning mouth syndrome (BMS) is characterized by burning of the oral mucosa in the absence of underlying dental or medical causes. The results of previous systematic reviews have generally been equivocal. However, findings for most interventions are based on searches of 5–10 years ago. This study therefore updates previous searches of randomized controlled trials (RCTs) for pain as assessed by Visual Analogue Scales (VAS). Secondary outcomes included quality of life, mood, taste and salivary flow.MethodsA search of MEDLINE and Embase up to 2016.Results24 RCTs were identified. Meta-analyses were impossible because of wide variations in study method and quality. The commonest interventions were alpha-lipoic acid (ALA) (8 comparisons), capsaicin or an analogue (4 comparisons), clonazepam (3 comparisons) and psychotherapy (2 comparisons). ALA and capsaicin led to significantly greater improvements in VAS (4 studies each), as did clonazepam (all 3 studies), at up to two month follow-up. However, capsaicin led to prominent dyspepsia. Psychotherapy significantly improved outcomes in one study at two and 12 month follow-up. Catauma and tongue-protectors also showed promise (one study each). There were no significant differences in any of the secondary outcomes except in the one study of tongue protectors.ConclusionsAt least in some studies and for some outcomes, ALA, clonazepam, capsaicin and psychotherapy may show modest benefit in the first two months. However, these conclusions are limited by generally short follow-up periods, high study variability and low participant numbers. Further RCTs with follow-up of at least 12 months are indicated.

Yoga for anxiety: A systematic review and meta-analysis of randomized controlled trials

Yoga has become a popular approach to improve emotional health. The aim of this review was to systematically assess and meta-analyze the effectiveness and safety of yoga for anxiety. Medline/PubMed, Scopus, the Cochrane Library, PsycINFO, and IndMED were searched through October 2016 for randomized controlled trials (RCTs) of yoga for individuals with anxiety disorders or elevated levels of anxiety. The primary outcomes were anxiety and remission rates, and secondary outcomes were depression, quality of life, and safety. Risk of bias was assessed using the Cochrane tool. Eight RCTs with 319 participants (mean age: 30.0–38.5 years) were included. Risk of selection bias was unclear for most RCTs. Meta-analyses revealed evidence for small short-term effects of yoga on anxiety compared to no treatment (standardized mean difference [SMD] = −0.43; 95% confidence interval [CI] = −0.74, −0.11; P = .008), and large effects compared to active comparators (SMD = −0.86; 95% CI = −1.56, −0.15; P = .02). Small effects on depression were found compared to no treatment (SMD = −0.35; 95% CI = −0.66, −0.04; P = .03). Effects were robust against potential methodological bias. No effects were found for patients with anxiety disorders diagnosed by Diagnostic and Statistical Manual criteria, only for patients diagnosed by other methods, and for individuals with elevated levels of anxiety without a formal diagnosis. Only three RCTs reported safety-related data but these indicated that yoga was not associated with increased injuries. In conclusion, yoga might be an effective and safe intervention for individuals with elevated levels of anxiety. There was inconclusive evidence for effects of yoga in anxiety disorders. More high-quality studies are needed and are warranted given these preliminary findings and plausible mechanisms of action.     

Chinese herbal medicine for insomnia: A systematic review of randomized controlled trials

Chinese herbal medicine (CHM), either in single herb or in herbal formula, has been used to treat insomnia for more than 2000 years. A systematic review including Chinese and English literature of randomized controlled trials was conducted to examine the efficacy, safety, and composition of CHM for insomnia. Among the 217 studies we have reviewed, only eight had a Jadad score ≥3, and seven out of these eight studies had at least one domain with high risks of bias. Meta-analyses of the studies with Jadad score ≥3 found that CHM was similar to Western medication (three studies) and placebo (three studies) in treating insomnia. Due to the poor methodological quality of the studies and the small number of trials included in meta-analyses, the current evidence is insufficient to support the efficacy of CHM for insomnia. The?frequency of adverse events associated with CHM was similar to that of placebo, but lower than with Western medication. Gui Pi Tang was the most commonly used standardized formula, while Suan Zao Ren (Ziziphus jujuba) was the most frequently used single herb. Further studies with a double-blind placebo-controlled design are needed to accurately determine the benefits and risks of CHM for insomnia.
