Cognitive-behavioural treatment for subacute and chronic neck pain

BACKGROUND: Although research on non-surgical treatments for neck pain (NP) is progressing, there remains uncertainty about the efficacy of cognitive-behavioural therapy (CBT) for this population. Addressing cognitive and behavioural factors might reduce the clinical burden and the costs of NP in society.OBJECTIVES: To assess the effects of CBT among individuals with subacute and chronic NP. Specifically, the following comparisons were investigated: (1) cognitive-behavioural therapy versus placebo, no treatment, or waiting list controls; (2) cognitive-behavioural therapy versus other types of interventions; (3) cognitive-behavioural therapy in addition to another intervention (e.g. physiotherapy) versus the other intervention alone.SEARCH METHODS: We searched CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, SCOPUS, Web of Science, and PubMed, as well as ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform up to November 2014. Reference lists and citations of identified trials and relevant systematic reviews were screened.SELECTION CRITERIA: We included randomised controlled trials that assessed the use of CBT in adults with subacute and chronic NP.DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the risk of bias in each study and extracted the data. If sufficient homogeneity existed among studies in the pre-defined comparisons, a meta-analysis was performed. We determined the quality of the evidence for each comparison with the GRADE approach.MAIN RESULTS: We included 10 randomised trials (836 participants) in this review. Four trials (40%) had low risk of bias, the remaining 60% of trials had a high risk of bias.The quality of the evidence for the effects of CBT on patients with chronic NP was from very low to moderate. There was low quality evidence that CBT was better than no treatment for improving pain (standard mean difference (SMD) -0.58, 95% confidence interval (CI) -1.01 to -0.16), disability (SMD -0.61, 95% CI -1.21 to -0.01), and quality of life (SMD -0.93, 95% CI -1.54 to -0.31) at short-term follow-up, while there was from very low to low quality evidence of no effect on various psychological indicators at short-term follow-up. Both at short- and intermediate-term follow-up, CBT did not affect pain (SMD -0.06, 95% CI -0.33 to 0.21, low quality, at short-term follow-up; MD -0.89, 95% CI -2.73 to 0.94, low quality, at intermediate-term follow-up) or disability (SMD -0.10, 95% CI -0.40 to 0.20, moderate quality, at short-term follow-up; SMD -0.24, 95% CI-0.54 to 0.07, moderate quality, at intermediate-term follow-up) compared to other types of interventions. There was moderate quality evidence that CBT was better than other interventions for improving kinesiophobia at intermediate-term follow-up (SMD -0.39, 95% CI -0.69 to -0.08, I(2) = 0%). Finally, there was very low quality evidence that CBT in addition to another intervention did not differ from the other intervention alone in terms of effect on pain (SMD -0.36, 95% CI -0.73 to 0.02) and disability (SMD -0.10, 95% CI -0.56 to 0.36) at short-term follow-up.For patients with subacute NP, there was low quality evidence that CBT was better than other interventions at reducing pain at short-term follow-up (SMD -0.24, 95% CI -0.48 to 0.00), while no difference was found in terms of effect on disability (SMD -0.12, 95% CI -0.36 to 0.12) and kinesiophobia.None of the included studies reported on adverse effects.AUTHORS' CONCLUSIONS: With regard to chronic neck pain, CBT was found to be statistically significantly more effective for short-term pain reduction only when compared to no treatment, but these effects could not be considered clinically meaningful. When comparing both CBT to other types of interventions and CBT in addition to another intervention to the other intervention alone, no differences were found. For patients with subacute NP, CBT was significantly better than other types of interventions at reducing pain at short-term follow-up, while no difference was found for disability and kinesiophobia. Further research is recommended to investigate the long-term benefits and risks of CBT including for the different subgroups of subjects with N

Time from adenosine di-phosphate receptor antagonist discontinuation to coronary bypass surgery in patients with acute coronary syndrome: meta-analysis and meta-regression

BACKGROUND: Adenosine di-phosphate receptor antagonists (ADPRAs) blunt hemostasis for several days after administration. This effect, aimed at preventing cardiac ischemic complications particularly in patients with acute coronary syndromes (ACS), may increase perioperative bleeding in the case of cardiac surgery. Practice Guidelines recommend withholding ADPRAs for at least 5days prior to surgery, though with a weak base of evidence. The purpose of this study was to systematically review observational and experimental studies of early or late preoperative discontinuation of ADPRAs prior to coronary artery bypass grafting (CABG) for patients with ACS. METHODS: MEDLINE, EMBASE, the Cochrane Library databases up to December 2011; and reference lists. Observational and experimental studies that compared early ADPRA discontinuation with late discontinuation, or no discontinuation, in patients with ACS undergoing CABG. RESULTS: There were 19 studies, including 14,046 participants, 395 deaths and 309 reoperations due to bleeding. ADPRA late discontinuation up to CABG was associated with an increased risk of postoperative mortality (OR 1.46, 95% confidence interval (CI) 1.10 to 1.93) and reoperations due to bleeding (OR 2.18; 95% CI 1.47 to 2.62). Between-study heterogeneity was low. Meta-analysis limited to high quality or prospective studies gave consistent results. In most instances, the 95% prediction intervals for summary risk estimates confirmed the risk across study groups. CONCLUSIONS: ADPRA late discontinuation prior to CABG is associated with an increased risk of death and reoperations due to bleeding in patients with ACS. The confidence in the estimates of risk for late discontinuation is moderate to high

Efficacy of Muscle Exercise in Patients with Muscular Dystrophy: A Systematic Review Showing a Missed Opportunity to Improve Outcomes

Background:Although muscular dystrophy causes muscle weakness and muscle loss, the role of exercise in the management of this disease remains controversial. Objective:The purpose of this systematic review is to evaluate the role of exercise interventions on muscle strength in patients with muscular dystrophy. Methods:We performed systematic electronic searches in Medline, Embase, Web of Science, Scopus and Pedro as well as a list of reference literature. We included trials assessing muscle exercise in patients with muscular dystrophy. Two reviewers independently abstracted data and appraised risk of bias. Results:We identified five small (two controlled and three randomized clinical) trials comprising 242 patients and two ongoing randomized controlled trials. We were able to perform two meta-analyses. We found an absence of evidence for a difference in muscle strength (MD 4.18, 95% CIs - 2.03 to 10.39; p = 0.91) and in endurance (MD -0.53, 95% CIs -1.11 to 0.05; p = 0.26). In both, the direction of effects favored muscle exercise. Conclusions:The first included trial about the efficacy of muscular exercise was published in 1978. Even though some benefits of muscle exercise were consistently reported across studies, the benefits might be due to the small size of studies and other biases. Detrimental effects are still possible. After several decades of research, doctors cannot give advice and patients are, thus, denied basic information. A multi-center randomized trial investigating the strength of muscles, fatigue, and functional limitations is needed. \ua9 2013 Gianola et al

Community pharmacists and stress at the counter : Qualitative exploratory initial italian research

Objectives: Community pharmacists are the most accessible healthcare professionals. They interact with a large number of patients who often show emotional concern. Their stressful and complex role is widely acknowledged, nonetheless research on their personal life is practically non-existent. Thus, we set out to qualitatively explore the emotional perceptions of pharmacists. Methods: Twenty experienced pharmacists were interviewed by a psychologist and a pharmacist. Data were analysed using an interpretative phenomenological analysis and coded using NVivo qualitative data analysis software. Key findings: Interviewed pharmacists admitted to different types of difficulties, mostly arising from a series of small, standalone episodes. Their stories describe intrinsic difficulties with their practice, rather than personal experiences. This study reveals the complexity of a community pharmacists' role - divided into health and hygiene advice, counselling and empathic relationships, and entrepreneurship. An important obstacle is the integration and concomitant implementation of these components. Endogenous factors such as personal experiences, personality and academic background, and exogenous factors such as social status of the patient population, legal and administrative issues and location, all affect pharmacists' ability to cope with their role. Conclusions: Improving health care can be obtained by incorporating community pharmacists into the healthcare team. Technical training is important in order to improve relationship skills and personal coping strategies. Further studies are recommended to provide a simple tool for measuring aspects of the personal and emotional aspects (inner life) of a community pharmacist

Constraint-induced movement therapy: trial sequential analysis applied to Cochrane collaboration systematic review results

Background: Trial sequential analysis (TSA) may establish when firm evidence about the efficacy of interventions is reached in a cumulative meta-analysis, combining a required information size with adjusted thresholds for conservative statistical significance. Our aim was to demonstrate TSA results on randomized controlled trials (RCTs) included in a Cochrane systematic review on the effectiveness of constraint-induced movement therapy (CIMT) for stroke patients. Methods: We extracted data on the functional independence measure (FIM) and the action research arm test (ARAT) from RCTs that compared CIMT versus other rehabilitative techniques. Mean differences (MD) were analyzed using a random-effects model. We calculated the information size and the cumulative Z-statistic, applying the O'Brien-Fleming monitoring boundaries. Results: We included data from 14 RCTs. In the conventional meta-analysis (seven trials, 233 patients), the effect of CIMT on FIM was reported as significant (MD 2.88, 95% CI 0.08 to 5.68; P = 0.04). The diversity-adjusted required information size was 142 patients, and the cumulative Z-score did not cross the trial sequential monitoring boundary for benefit (adjusted 95% CI -0.02 to 5.78). The effect of CIMT on ARAT (nine trials, 199 patients) was reported as significant (MD 7.78, 95% CI 1.19 to 14.37; P = 0.02). However, the diversity-adjusted required information size was 252 patients, and the Z-score did not cross the trial sequential monitoring boundary for benefit (adjusted 95% CI -0.06 to 15.62). Conclusions: Although conventional meta-analyses of CIMT reached statistical significance, their overall results remain inconclusive and might be spurious. Researchers should not be overconfident on CIMT efficacy based on the results of meta-analyses and derived recommendations

Sustained versus standard inflations during neonatal resuscitation to prevent mortality and improve respiratory outcomes

Background: At birth, infants' lungs are fluid-filled. For newborns to have a successful transition, this fluid must be replaced by air to enable effective breathing. Some infants are judged to have inadequate breathing at birth and are resuscitated with positive pressure ventilation (PPV). Giving prolonged (sustained) inflations at the start of PPV may help clear lung fluid and establish gas volume within the lungs. Objectives: To assess the efficacy of an initial sustained (> 1 second duration) lung inflation versus standard inflations (\ue2\u89\ua4 1 second) in newly born infants receiving resuscitation with intermittent PPV. Search methods: We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 1), MEDLINE via PubMed (1966 to 17 February 2017), Embase (1980 to 17 February 2017), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 17 February 2017). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles to identify randomised controlled trials and quasi-randomised trials. Selection criteria: Randomised controlled trials (RCTs) and quasi-RCTs comparing initial sustained lung inflation (SLI) versus standard inflations given to infants receiving resuscitation with PPV at birth. Data collection and analysis: We assessed the methodological quality of included trials using Cochrane Effective Practice and Organisation of Care Group (EPOC) criteria (assessing randomisation, blinding, loss to follow-up, and handling of outcome data). We evaluated treatment effects using a fixed-effect model with risk ratio (RR) for categorical data and mean, standard deviation (SD), and weighted mean difference (WMD) for continuous data. We assessed the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Main results: Eight trials enrolling 941 infants met our inclusion criteria. Investigators in seven trials (932 infants) administered sustained inflation with no chest compressions. Use of sustained inflation had no impact on the primary outcomes of this review - mortality in the delivery room (typical RR 2.66, 95% confidence interval (CI) 0.11 to 63.40; participants = 479; studies = 5; I2 not applicable) and mortality during hospitalisation (typical RR 1.01, 95% CI 0.67 to 1.51; participants = 932; studies = 7; I2 = 19%); the quality of the evidence was low for death in the delivery room (limitations in study design and imprecision of estimates) and was moderate for death before discharge (limitations in study design of most included trials). Amongst secondary outcomes, duration of mechanical ventilation was shorter in the SLI group (mean difference (MD) -5.37 days, 95% CI -6.31 to -4.43; participants = 524; studies = 5; I2 = 95%; low-quality evidence). Heterogeneity, statistical significance, and magnitude of effects of this outcome are largely influenced by a single study: When this study was removed from the analysis, the effect was largely reduced (MD -1.71 days, 95% CI -3.04 to -0.39, I2 = 0%). Results revealed no differences in any of the other secondary outcomes (e.g. rate of endotracheal intubation outside the delivery room by 72 hours of age (typical RR 0.93, 95% CI 0.79 to 1.09; participants = 811; studies = 5; I2 = 0%); need for surfactant administration during hospital admission (typical RR 0.97, 95% CI 0.86 to 1.10; participants = 932; studies = 7; I2 = 0%); rate of chronic lung disease (typical RR 0.95, 95% CI 0.74 to 1.22; participants = 683; studies = 5; I2 = 47%); pneumothorax (typical RR 1.44, 95% CI 0.76 to 2.72; studies = 6, 851 infants; I2 = 26%); or rate of patent ductus arteriosus requiring pharmacological treatment (typical RR 1.08, 95% CI 0.90 to 1.30; studies = 6, 745 infants; I2 = 36%). The quality of evidence for these secondary outcomes was moderate (limitations in study design of most included trials - GRADE) except for pneumothorax (low quality: limitations in study design and imprecision of estimates - GRADE). Authors' conclusions: Sustained inflation was not better than intermittent ventilation for reducing mortality in the delivery room and during hospitalisation. The number of events across trials was limited, so differences cannot be excluded. When considering secondary outcomes, such as need for intubation, need for or duration of respiratory support, or bronchopulmonary dysplasia, we found no evidence of relevant benefit for sustained inflation over intermittent ventilation. The duration of mechanical ventilation was shortened in the SLI group. This result should be interpreted cautiously, as it can be influenced by study characteristics other than the intervention. Future RCTs should aim to enrol infants who are at higher risk of morbidity and mortality, should stratify participants by gestational age, and should provide more detailed monitoring of the procedure, including measurements of lung volume and presence of apnoea before or during the SLI

Pharmacokinetics of acute tryptophan depletion using a gelatin-based protein in male and female Wistar rats

The essential amino acid tryptophan is the precursor of the neurotransmitter serotonin. By depleting the body of tryptophan, brain tryptophan and serotonin levels are temporarily reduced. In this paper, several experiments are described in which dose and treatment effects of acute tryptophan depletion (ATD) using a gelatin-based protein–carbohydrate mixture were studied in male and female Wistar rats. Two or three doses of tryptophan depleting mixture resulted in 65–70% depletion after 2–4 h in males. ATD effects were similar in females, although females may return to baseline levels faster. Treatment effects after four consecutive days of ATD were similar to the effects of 1 day of treatment. Object recognition memory was impaired 2, 4, and 6 h after the first of two doses of ATD, suggesting that the central effects occurred rapidly and continued at least 6 h, in spite of decreasing treatment effects on plasma tryptophan levels at that time point. The method of acute tryptophan depletion described here can be used to study the relationship between serotonin and behaviour in both male and female rats
