Developing a framework for arts in health programs targeting individuals with chronic pain: a mixed-methods study of practitioners. Public Health 2021; 197:68-74. [PMID: 34352682 DOI: 10.1016/j.puhe.2021.05.032] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 04/16/2021] [Accepted: 05/26/2021] [Indexed: 11/19/2022]
Abstract
OBJECTIVES Chronic pain is a leading cause of morbidity and disability across the world. Cultural engagement may be a valuable tool in addressing the social disconnection that often accompanies chronic pain. This study sought to develop a framework for arts in health programs targeting individuals with chronic pain. STUDY DESIGN Sequential explanatory mixed-methods study. METHODS Web-based, cross-sectional survey sent to arts and cultural professionals to assess their experience with arts in health programming. Semi-structured interviews conducted with a sample of survey respondents to explore their perspectives on targeted arts in health programming for individuals with chronic pain. RESULTS Between October 2019 and January 2020, 208 surveys were completed by arts and cultural professionals. One hundred and twenty (58%) of the respondents indicated that they currently run an arts in health or museums in health program. Among these 120 respondents, 52 (43%) targeted older adults, 50 (42%) targeted individuals with mental health concerns, and 18 (15%) targeted individuals living with pain. Improving well-being (101 [84%]) and reducing social isolation (90 [75%]) were the most common intended program outcomes, while improving pain was the least common outcome (26 [22%]). Fifteen survey respondents were interviewed. Interviewees identified four interdependent themes regarding best practices for arts in health programs pertaining to (1) program content and structure, (2) program facilitation, (3) partnerships, and (4) programs for individuals with chronic pain. CONCLUSIONS The cultural sector can support chronic pain prevention and treatment efforts through the development of specialized programs. This study provides a framework for developing arts in health programs that support individuals living with chronic pain.

Efficacy of medical and ablation therapy for inappropriate sinus tachycardia: A single-center experience. J Cardiovasc Electrophysiol 2021; 32:1053-1061. [PMID: 33566447 DOI: 10.1111/jce.14942] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 12/18/2020] [Accepted: 01/10/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Effective therapy for inappropriate sinus tachycardia (IST) remains challenging with high rates of treatment failure and symptom recurrence. It is uncertain how effective pharmacotherapy and procedural therapy are long-term, with poor response to medical therapy in general. METHODS We retrospectively reviewed all patients with the diagnosis of IST at a tertiary academic medical center from 1998 to 2018. We extracted data related to prescribing patterns and symptom response to medical therapy and sinus node modification (SNM), assessing efficacy and periprocedural complication rates. RESULTS A total of 305 patients with a formal diagnosis of IST were identified, with 259 (84.9%) receiving at least one prescription medication related to the condition. Beta-blockers were the most commonly used medication (n = 245), with a majority of patients reporting no change or worsening of symptoms, and poor response was seen to other medication classes. Improvement was seen significantly more often with ivabradine than beta blockers, though the sample size was limited (p = .003). Fifty-five patients (18.0% of all IST patients), mean age 32.0 ± 9.1 years, underwent a SNM procedure, with an average of 1.8 ± 0.9 procedures per patient. Acute symptomatic improvement (<6 months) was seen in 58.2% of patients. Long-term complete resolution of symptoms was seen in 5.5% of patients, modest improvement in 29.1%, and no long-term benefit was seen in 65.5% of patients. CONCLUSIONS Among all medical therapies, there were high rates of treatment failure or symptom worsening in over three-quarters of patients in our study. Ivabradine was most beneficial, though the sample size was small. While most patients receiving SNM ablation for IST perceive an acute symptomatic improvement, almost two-thirds of patients have no long-term improvement, and resolution of symptoms is quite rare. AV node ablation with pacemaker implantation following lack of response to SNM offered increased success, though the sample size was limited.

Sinus rhythm heart rate increase after atrial fibrillation ablation is associated with lower risk of arrhythmia recurrence. PACING AND CLINICAL ELECTROPHYSIOLOGY: PACE 2021; 44:651-656. [PMID: 33592679 DOI: 10.1111/pace.14197] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 02/09/2021] [Accepted: 02/14/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Pulmonary vein isolation (PVI) with autonomic modulation may be more successful than PVI alone for atrial fibrillation (AF) ablation and may be signaled by changes in sinus rhythm heart rate (HR) post ablation. We sought to determine if a change in sinus rhythm HR predicted AF recurrence post PVI. METHODS Patients who underwent AF ablation from 2000 to 2011 were included if sinus rhythm was noted on ECG within 90 days pre and 7 days post ablation. Basic ECG interval and HR changes were analyzed and outcomes determined. RESULTS A total of 1152 patients were identified (74.3% male, mean age 57 ± 11 years). Mean AF duration was 5.2 ± 5.3 years. Paroxysmal AF was noted in 712 (61.8%) of the patients. Mean EF was 61% ± 6%. Sinus rhythm HR was 61 ± 11 pre-ablation and 76 ± 13 bpm post-ablation (27% ± 24% increase, p < .001). The ability of relative HR change post-ablation to predict AF recurrence was borderline (hazard ratio 0.65 [0.41-1.01], p = .067). With patients separated into quartiles based on the relative HR change, the upper quartile with the largest relative increase in HR had a significantly lower rate of AF recurrence compared to the lowest quartile following multi variable modeling (p = .038). There were significant changes in PR (171 ± 28 to 167 ± 30 ms) and QTc (424 ± 25 to 434 ± 29 ms) intervals (both p < .001) but these were not predictive of outcome. CONCLUSION Relative changes in HR post AF ablation correlates with AF recurrence. Further prospective studies are needed to confirm this relationship.

Thoughts, beliefs and concepts concerning infectious childhood diseases of physicians practicing homeopathic, anthroposophic and conventional medicine - a qualitative study. BMC Complement Med Ther 2021; 21:46. [PMID: 33499846 PMCID: PMC7835107 DOI: 10.1186/s12906-021-03216-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Accepted: 01/12/2021] [Indexed: 11/30/2022] Open
Abstract
Background Physicians who include complementary medicine in their practice are thought to have an understanding of health and disease different from that of colleagues practicing conventional medicine. The aim of this study was to identify and compare the thoughts and concepts concerning infectious childhood diseases (measles, mumps, rubella, chickenpox, pertussis and scarlet fever) of physicians practicing homeopathic, anthroposophic and conventional medicine. Methods This qualitative study used semistructured interviews. Participating physicians were either general practitioners or pediatricians. Data collection and analysis were guided by a grounded theory approach. Results Eighteen physicians were interviewed (6 homeopathic, 6 anthroposophic and 6 conventional). All physicians agreed that while many classic infectious childhood diseases such as measles, mumps and rubella are rarely observed today, other diseases, such as chickenpox and scarlet fever, are still commonly diagnosed. All interviewed physicians vaccinated against childhood diseases. A core concern for physicians practicing conventional medicine was the risk of complications of the diseases. Therefore, it was considered essential for them to advise their patients to strictly follow the vaccination schedule. Homeopathic-oriented physicians viewed acute disease as a biological process necessary to strengthen health, fortify the immune system and increase resistance to chronic disease. They tended to treat infectious childhood diseases with homeopathic remedies and administered available vaccines as part of individual decision-making approaches with parents. For anthroposophic-oriented physicians, infectious childhood diseases were considered a crucial factor in the psychosocial growth of children. They tended to treat these diseases with anthroposophic medicine and underlined the importance of the family’s resources. Informing parents about the potential benefits and risks of vaccination was considered important. All physicians agreed that parent-delivered loving care of a sick child could benefit the parent-child relationship. Additionally, all recognized that existing working conditions hindered parents from providing such care for longer durations of time. Conclusions The interviewed physicians agreed that vaccines are an important aspect of modern pediatrics. They differed in their approach regarding when and what to vaccinate against. The different conceptual understandings of infectious childhood diseases influenced this decision-making. A survey with a larger sample would be needed to verify these observations.

Abstract
Left bundle branch block may be due to conduction system degeneration or a reflection of myocardial pathology. Left bundle branch block may also develop following aortic valve disease or cardiac procedures. Patients with heart failure with reduced ejection fraction and left bundle branch block may respond positively to cardiac resynchronization therapy. Lead placement via the coronary sinus is the mainstay approach of cardiac resynchronization therapy. However, other options, including physiological pacing, are being explored. In this review, we summarize the salient pathophysiologic and clinical aspects of left bundle branch block, as well as current and future strategies for management.

Natural history and clinical outcomes of inappropriate sinus tachycardia. J Cardiovasc Electrophysiol 2019; 31:137-143. [PMID: 31749258 DOI: 10.1111/jce.14288] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Revised: 10/24/2019] [Accepted: 11/16/2019] [Indexed: 12/17/2022]
Abstract
BACKGROUND Limited data are available regarding the demographics, disease associations, and long-term prognosis of patients with inappropriate sinus tachycardia (IST). OBJECTIVE To establish epidemiologic data for patients with IST, including symptom onset, comorbid disease, and long-term outcomes. METHODS We retrospectively reviewed all patients with an IST diagnosis at the Mayo Clinic (Rochester, MN) during a 20-year period (1998-2018). We extracted demographic data and clinical outcomes compared to an age and gender-matched control group with atrioventricular nodal reentry tachycardia (AVNRT). RESULTS Within the study period, a total of 305 patients with IST were identified (mean follow-up 3.5 years) with 92.1% female and mean age 33.2 ± 11.2 years. The most frequently identified circumstances triggering the condition included pregnancy (7.9%) and infectious illness (5.9%) while the most common comorbid conditions were depression (25.6%) and anxiety (24.6%). At diagnosis, the mean left ventricular ejection fraction (LVEF) was 62.3 ± 6.2%, with 77 patients having follow-up echocardiographic data. No significant difference in LVEF was seen after a mean 4.9 ± 4.3-year follow-up (baseline LVEF 59.8 ± 10.7% vs subsequent 61.4 ± 8.1%; P = .2971). Two deaths occurred within the study period, with one related to myocardial infarction and the other noncardiac; compared to an age and gender-matched AVNRT control group there was no excess mortality during the follow-up period. CONCLUSIONS In our study cohort, IST predominately affects young females with structurally normal hearts and modest coexistent psychiatric disease. In most cases of IST, a major event occurring just before or at the time of diagnosis could not be identified, although nearly 8% of patients first noted symptoms during or shortly after pregnancy. In our cohort, there was no evidence of cardiomyopathy or mortality related to IST.

Association between the Charlson comorbidity index and outcomes after implantable cardioverter defibrillator generator replacement. PACING AND CLINICAL ELECTROPHYSIOLOGY: PACE 2019; 42:1236-1242.

Abstract
BACKGROUND Recipients of implantable cardioverter defibrillator (ICD) generator replacement with multiple medical comorbidities may be at higher risk of adverse outcomes that attenuate the benefit of ICD replacement. The aim of this investigation was to study the association between the Charlson comorbidity index (CCI) and outcomes after ICD generator replacement. METHODS All patients undergoing first ICD generator replacement at Mayo Clinic, Rochester and Beth Israel Deaconess Medical Center, Boston between 2001 and 2011 were identified. Outcomes included: (a) all-cause mortality, (b) appropriate ICD therapy, and (c) death prior to appropriate therapy. Multivariable Cox regression analysis was performed to assess association between CCI and outcomes. RESULTS We identified 1421 patients with mean age of 69.6 ± 12.1 years, 81% male and median (range) CCI of 3 (0-18). During a mean follow-up of 3.9 ± 3 years, 52% of patients died, 30.6% experienced an appropriate therapy, and 23.6% died without experiencing an appropriate therapy. In multivariable analysis, higher CCI score was associated with increased all-cause mortality (Hazard ratio, HR 1.10 [1.06-1.13] per 1 point increase in CCI, P < .001), death without prior appropriate therapy (HR 1.11 [1.07-1.15], P < .0001), but not associated with appropriate therapy (HR 1.01 [0.97-1.05], P = .53). Patients with CCI ≥5 had an annual risk of death of 12.2% compared to 8.7% annual rate of appropriate therapy. CONCLUSIONS CCI is predictive of mortality following ICD generator replacement. The benefit of ICD replacement in patients with CCI score ≥5 should be investigated in prospective studies.

Diagnostic Accuracy of Echocardiography and Intraoperative Surgical Inspection of the Unicuspid Aortic Valve. Am J Cardiol 2019; 123:967-971.

Abstract
Unicuspid aortic valve (UAV) is a rare malformation that is often difficult to distinguish from a bicuspid aortic valve (BAV) with commissural fusion by echocardiography or intraoperative surgical inspection. This study assessed the accuracy of intraoperative surgical inspection and two-dimensional echocardiography in diagnosing UAV compared to a gold standard of pathological diagnosis. The Mayo Clinic echocardiographic database, tissue registry database and electronic medical record were searched for all patients assigned a diagnosis of UAV by any technique. Transthoracic (TTE), transesophageal (TEE) echocardiographic, and surgical diagnoses were compared to pathological diagnosis as the standard. A clinical diagnosis of UAV was applied to 380 patients by 1 or more method and in 196 (52%) a pathologic evaluation was available to compare to the clinical description given by TTE, TEE, or surgical inspection. Of these 196 patients, only 58 (30%) had a pathological diagnosis of UAV; the majority were found to be BAVs by pathologic evaluation (n = 132, 67%). For diagnosing UAV, the sensitivity and specificity were 15% and 87% for TTE, 28%, and 82% for TEE, and 52% and 51% for surgical inspection, respectively. Valves with bicuspid morphology and extensive commissural fusion were frequently misclassified as UAV by all methods. In conclusion, intraoperative surgical inspection and echocardiography have limitations for diagnosing UAV due to difficulties in accurately assigning a correct morphological diagnosis, which suggests that the current understanding of the natural history of UAV may be inaccurate.

Abstract
BACKGROUND The prognostic significance of paced QRS complex morphology on surface ECG remains unclear. This study aimed to assess long-term outcomes associated with variations in the paced QRS complex. METHODS Adult patients who underwent dual-chamber pacemaker implantation with 20% or more ventricular pacing and a 12-lead ECG showing a paced complex were included. The paced QRS was analyzed in leads I and aVL. Long-term clinical and echocardiographic outcomes were compared at 5 years. RESULTS The study included 844 patients (43.1% female; age 75.0 ± 12.1). Patients with a longer paced QRS (pQRS) duration in lead I had a lower rate of atrial fibrillation (HR 0.80; p = 0.03) and higher rate of systolic dysfunction (HR 1.17; p < 0.001). Total pacing complex (TPC) duration was linked to higher rates of ICD implantation (HR 1.18; p = 0.04) and systolic dysfunction (HR 1.22, p < 0.001). Longer paced intrinsicoid deflection (pID) was associated with less atrial fibrillation (HR 0.75; p = 0.01), more systolic dysfunction (HR 1.17; p < 0.001), ICD implantation (HR 1.23; p = 0.04), and CRT upgrade (HR 1.23; p = 0.03). Exceeding thresholds for TPC, pQRS, and pID of 170, 146, and 112 ms in lead I, respectively, was associated with a substantial increase in systolic dysfunction over 5 years (p < 0.001). CONCLUSIONS Longer durations of all tested parameters in lead I were associated with increased rates of left ventricular systolic dysfunction. ICD implantation and CRT upgrade were also linked to increased TPC and pID durations. Paradoxically, patients with longer pID and pQRS had less incident atrial fibrillation.

Abstract
Cardiac resynchronization therapy has been proven to be clearly beneficial for patients with heart failure, a prolonged QRS duration, and a left ventricular ejection fraction ≤35%. Ejection fraction cutoff, however, is arbitrary and very likely excludes many patients who could benefit from cardiac resynchronization. This article describes the major detrimental effects of left bundle branch block and summarizes the data regarding the potential beneficial effects of cardiac resynchronization in patients with a left ventricular ejection fraction greater than 35%.

Abstract
OBJECTIVES This study aimed to determine if epicardial cooling could repeatedly terminate induced atrial fibrillation (AF) in a canine heart. BACKGROUND Rapid termination of AF could control symptoms and prevent atrial remodeling; however, defibrillation by internal electrical cardioversion is not tolerable to most patients. Cooling of the epicardium slows atrial conduction and may provide a less painful method to quickly terminate AF. METHODS AF was induced with atrial myocardial epinephrine injections and rapid atrial pacing in an open-chest canine. Attempts at termination were performed with a small metal device that was either cooled to 5°C or kept at body temperature (control module). The device was placed on the epicardial surface in the oblique sinus. The time from device contact to termination of AF was recorded. RESULTS In 5 different canine studies, there were 57 attempts at AF termination with either a 5°C module (34 attempts) or a control module (23 attempts). The median (interquartile range [IQR]) time to AF termination was 24 s (IQR: 15 to 35 s) for the 5°C therapy and 100 s (IQR: 47 to 240 s) for the body temperature treatments (p < 0.001). In the control group, there were 8 AF episodes that continued up to 4 min. Subsequent application of the 5°C cooling module terminated AF in all cases. CONCLUSIONS Epicardial cooling in the oblique sinus is effective for repeated termination of AF in a canine heart. If reproduced in human studies, epicardial cooling with an implantable device may provide a method for management of patients with AF.

Abstract
Background Current thermal ablation methods for atrial fibrillation, including radiofrequency and cryoablation, have a suboptimal success rate. To avoid pulmonary vein (PV) stenosis, ablation is performed outside of the PV, despite the importance of triggers inside the vein. We previously reported on the acute effects of a novel direct current electroporation approach with a balloon catheter to create lesions inside the PVs in addition to the antrum. In this study, we aimed to determine whether the effects created by this nonthermal ablation method were associated with irreversible lesions and whether PV stenosis or other adverse effects occurred after a survival period. Methods and Results Initial and survival studies were performed in 5 canines. At the initial study, the balloon catheter was inflated to contact the antrum and interior of the PV. Direct current energy was delivered between 2 electrodes on the catheter in ECG‐gated 100 μs pulses. A total of 10 PVs were treated demonstrating significant acute local electrogram diminution (mean amplitude decrease of 61.2±19.8%). After the survival period (mean 27 days), computed tomography imaging showed no PV stenosis. On histologic evaluation, transmural, although not circumferential, lesions were seen in each treated vein. No PV stenosis or esophageal injury was present. Conclusions Irreversible, transmural lesions can be created inside the PV without evidence of stenosis after a 27‐day survival period using this balloon‐based direct current ablation approach. These early data show promise for an ablation approach that could directly treat PV triggers in addition to traditional PV antrum ablation.

Abstract
INTRODUCTION Cardiac pacing from the right ventricular apex is associated with detrimental long-term effects and nonapical pacing locations may be associated with improved outcomes. There is little data regarding complications with nonapical lead positions. The aim of this study was to assess long-term outcomes and lead-related complications associated with differing ventricular lead tip position. METHODS AND RESULTS All adult patients who underwent dual-chamber pacemaker implantation from 2004 to 2014 were included if they had postprocedure chest radiographs amenable to lead position determination. Long-term outcomes and lead-related complication rates were recorded. These were compared at 5 years between: (1) apical and septal leads, (2) apical and nonseptal nonapical (NSNA), and (3) apical and septal with >40% ventricular pacing. We retrospectively evaluated 3,450 patients, which included 238 with a septal position and 733 with NSNA lead positions. Septal lead position was associated with a lower mortality compared to apical leads (24% vs. 31%, P = 0.02). In patients with greater than 40% pacing, septal leads were associated with significantly higher rates of incident atrial fibrillation compared to apical leads (49% vs. 34%, P = 0.04). NSNA positions were associated with a significantly higher rate of lead dislodgement (4% vs. 2%, P = 0.005) and need for revision (8% vs. 5%, P = 0.005). CONCLUSIONS Septal pacemaker lead position is associated with a lower mortality compared to apically placed leads, but a higher incidence of atrial fibrillation with higher percentage ventricular pacing. NSNA lead locations are associated with more complications and should be avoided.

Abstract
There is uncertainty regarding how long the effects of acupuncture treatment persist after a course of treatment. We aimed to determine the trajectory of pain scores over time after acupuncture, using a large individual patient data set from high-quality randomized trials of acupuncture for chronic pain. The available individual patient data set included 29 trials and 17,922 patients. The chronic pain conditions included musculoskeletal pain (low back, neck, and shoulder), osteoarthritis of the knee, and headache/migraine. We used meta-analytic techniques to determine the trajectory of posttreatment pain scores. Data on longer term follow-up were available for 20 trials, including 6376 patients. In trials comparing acupuncture to no acupuncture control (wait-list, usual care, etc), effect sizes diminished by a nonsignificant 0.011 SD per 3 months (95% confidence interval: -0.014 to 0.037, P = 0.4) after treatment ended. The central estimate suggests that approximately 90% of the benefit of acupuncture relative to controls would be sustained at 12 months. For trials comparing acupuncture to sham, we observed a reduction in effect size of 0.025 SD per 3 months (95% confidence interval: 0.000-0.050, P = 0.050), suggesting approximately a 50% diminution at 12 months. The effects of a course of acupuncture treatment for patients with chronic pain do not seem to decrease importantly over 12 months. Patients can generally be reassured that treatment effects persist. Studies of the cost-effectiveness of acupuncture should take our findings into account when considering the time horizon of acupuncture effects. Further research should measure longer term outcomes of acupuncture.

Abstract
CLINICAL INTRODUCTION An asymptomatic 29-year-old woman presented for prenatal counselling. She had a history of a heart murmur since childhood and a previous echocardiogram suggesting 'enlargement of the heart'. Physical exam revealed normal jugular venous pressure and contour. Precordial palpation was unremarkable. Auscultation, however, was abnormal; findings on inspiration and expiration are presented in Figure 1, sound clip. QUESTION Based on the phonocardiogram and online supplementary audio clip, which of the following is correct? An early diastolic filling sound (S3) is heard, indicating increased right ventricular filling pressures.An ejection click without respiratory variation and a systolic ejection murmur are heard, consistent with bicuspid aortic valve stenosis.An ejection click with respiratory variation and a systolic ejection murmur are heard, consistent with pulmonic valve stenosis.A holosystolic murmur with inspiratory augmentation is heard, indicating tricuspid regurgitation.

Abstract
BACKGROUND The effectiveness of implantable cardioverter-defibrillators (ICDs) for primary prevention of sudden death in patients with an ejection fraction (EF) ≤ 35% and clinical heart failure is well established. However, outcomes after replacement of the ICD generator in patients with recovery of EF to >35% and no previous therapies are not well characterized. METHODS AND RESULTS Between 2001 and 2011, generator replacement was performed at 2 tertiary medical centers in 253 patients (mean age, 68.3 ± 12.7 years; 82% men) who had previously undergone ICD placement for primary prevention but subsequently never received appropriate ICD therapy. EF had recovered to > 35% in 72 of 253 (28%) patients at generator replacement. During median (quartiles) follow-up of 3.3 (1.8-5.3) years after generator replacement, 68 of 253 (27%) experienced appropriate ICD therapy. Patients with EF ≤ 35% were more likely to experience ICD therapy compared with those with EF > 35% (12% versus 5% per year; hazard ratio, 3.57; P = 0.001). On multivariable analysis, low EF predicted appropriate ICD therapy after generator replacement (hazard ratio, 1.96 [1.35-2.87] per 10% decrement; P = 0.001). Death occurred in 25% of patients 5 years after generator replacement. Mortality was similar in patients with EF ≤ 35% and > 35% (7% versus 5% per year; hazard ratio, 1.10; P = 0.68). Atrial fibrillation (3.24 [1.63-6.43]; P < 0.001) and higher blood urea nitrogen (1.28 [1.14-1.45] per increase of 10 mg/dL; P < 0.001) were associated with mortality. CONCLUSIONS Although approximately one fourth of patients with a primary prevention ICD and no previous therapy have EF >35% at the time of generator replacement, these patients continue to be at significant risk for appropriate ICD therapy (5% per year). These data may inform decisions on ICD replacement.

Abstract
Chest pain can occur after cardiac device lead placement through various mechanisms. Commonly, this is secondary to perforation. We present four cases of unusual chest pain syndromes secondary to device leads with normal function and position without evidence of typical complications. The possible etiologies and management considerations for these cases are discussed.

Abstract
In chronic pain studies involving acupuncture treatments, the size of the effect between acupuncture and a sham acupuncture control is usually small. By contrast, when acupuncture is compared to an active control group (usual care or standard treatment), the size of the effect is generally moderate and clinically relevant. Factors such as treatment setting, the expectations of patient and practitioner, and the interaction between patient and practitioner differ for different treatments and may influence the study outcome. In acupuncture, these factors seem to play a role. Acupuncture research is helpful in stimulating placebo research and illuminates a variety of aspects that influence the placebo response. The influence of different types of patient-practitioner interaction and their underlying mechanisms seem to be a clinically relevant area for future research, but should be researched in less complex placebo models than sham acupuncture.

Abstract
BACKGROUND To investigate the effects of stimulated and non-stimulated manual acupuncture at ST36 and PC6 on gastric myoelectrical activity and autonomic function. METHODS A total of 65 healthy volunteers were randomly assigned to a 1: 1: 2 ratio to receive either 15 min of verum acupuncture (VA) with stimulation followed by 15 min of VA without stimulation (nsVA), or 15 min of nsVA followed by 15 min of VA with stimulation (sVA), or 30 min of sham acupuncture (SA). Measures of autonomic function included electrogastrogram, electrocardiogram, impedance cardiography and assessment of blood pressure, breathing frequency, and electrodermal activity. Outcome parameters were compared between VA and SA, and between sVA and nsVA. The percentage of regular gastric slow waves (normogastria) was defined as the primary outcome. KEY RESULTS The percentage of normogastria was not significantly different between VA and SA. Differences in secondary outcomes such as power spectrum of gastric slow waves and heart rate variability parameters were pronounced in the comparison of sVA and nsVA. During sVA, the percentage of normogastria was lower (P = 0.005), the percentage of bradygastria was higher (P = 0.003) and power ratio was higher (P < 0.001), systolic blood pressure was lower (P = 0.039) and RMSSD was higher (P < 0.001) as compared with nsVA. CONCLUSIONS & INFERENCES Our study suggests that manual stimulation of acupuncture needles at ST36 and PC6 affects gastric myoelectrical as well as cardiac activities in healthy volunteers. The effect of stimulation in acupuncture deserves further investigation.

Abstract
Design Prospective multicentre observational study. Objective To evaluate details and effects of homeopathic treatment in patients with psoriasis in usual medical care. Methods Primary care patients were evaluated over 2 years using standardized questionnaires, recording diagnoses and complaints severity, health-related quality of life (QoL), medical history, consultations, all treatments, and use of other health services. Results Forty-five physicians treated 82 adults, 51.2% women, aged 41.6 +/- 12.2 (mean +/- SD) years. Patients had psoriasis for 14.7 +/- 11.9 years; 96.3% had been treated before. Initial case taking took 127 +/- 47 min. The 7.4 +/- 7.4 subsequent consultations (duration: 19.4 +/- 10.5 min) cumulated to 169.0 +/- 138.8 min. Patients received 6.0 +/- 4.9 homeopathic prescriptions. Diagnoses and complaints severity improved markedly with large effect sizes (Cohen's d= 1.02-2.09). In addition, QoL improved (SF-36 physical component score d = 0.26, mental component score d = 0.49), while conventional treatment and health service use were considerably reduced. Conclusions Under classical homeopathic treatment, patients with psoriasis improved in symptoms and QoL.

Abstract
We aimed to investigate the effectiveness of acupuncture in addition to routine care in patients with primary headache (> 12 months, two or more headaches/month) compared with treatment with routine care alone and whether the effects of acupuncture differ in randomized and non-randomized patients. In a randomized controlled trial plus non-randomized cohort, patients with headache were allocated to receive up to 15 acupuncture sessions over 3 months or to a control group receiving no acupuncture during the first 3 months. Patients who did not consent to randomization received acupuncture treatment immediately. All subjects were allowed usual medical care in addition to study treatment. Number of days with headache, intensity of pain and health-related quality of life (SF-36) were assessed at baseline, and after 3 and 6 months using standardized questionnaires. Of 15,056 headache patients (mean age 44.1 +/- 12.8 years, 77% female), 1613 were randomized to acupuncture and 1569 to control, and 11,874 included in the non-randomized acupuncture group. At 3 months, the number of days with headache decreased from 8.4 +/- 7.2 (estimated mean +/-s.e.) to 4.7 +/- 5.6 in the acupuncture group and from 8.1 +/- 6.8 to 7.5 +/- 6.3 in the control group (P < 0.001). Similarly, intensity of pain and quality of life improvements were more pronounced in the acupuncture vs. control group (P < 0.001). Treatment success was maintained through 6 months. The outcome changes in non-randomized patients were similar to those in randomized patients. Acupuncture plus routine care in patients with headache was associated with marked clinical improvements compared with routine care alone.

Abstract
The aim was to assess costs and cost-effectiveness of additional acupuncture treatment in patients with headache compared with patients receiving routine care alone. A randomized, controlled trial was conducted, including patients (> or =18 years old) with primary headache (more than 12 months, at least two headaches/month). Outcome parameters were quality of life (Short Form 36), direct and indirect costs differences during the 3-month study period and the incremental cost-effectiveness ratio (ICER) of acupuncture treatment. A total of 3182 patients (1613 acupuncture; 1569 controls) with headache were included (77.4% women, mean age and standard deviation 42.6 +/- 12.3; 22.6% men, 47.2 +/- 13.4). Over 3 months costs were higher in the acupuncture group compared with the control [euro857.47; 95% confidence interval 790.86, 924.07, vs. euro527.34 (459.81, 594.88), P < 0.001, mean difference: euro330.12 (235.27, 424.98)]. This cost increase was primarily due to costs of acupuncture [euro365.64 (362.19, 369.10)]. The ICER was euro11 657 per QALY gained. According to international cost-effectiveness threshold values, acupuncture is a cost-effective treatment in patients with primary headache.

Abstract
INTRODUCTION Gender medicine investigates sex-related differences in morbidity and mortality. The consideration of relevant sex-specific factors should lead to an improvement in prevention, diagnosis and therapy. The goal of this survey was to obtain a picture of the current status and the future potential of gender medicine from the perspective of clinicians. METHODS A questionnaire on gender medicine in education, diagnosis, therapy and research was sent to all professors as well as a random sample of assistant medical directors specializing in gynaecology, cardiology and neurology at German university hospitals. RESULTS The response rate was 55% (N = 136). The present importance of gender medicine in Germany was rated by 83% of the respondents as low, and 62% said that gender medicine should be a required subject during medical studies. Through more consideration of gender-specific aspects, 72% expect a more exact diagnosis, 80% more specific treatment, 77% the avoidance of secondary complications, 64% a reduction of mortality and 73% the reduction of consequential costs. DISCUSSION The current importance of gender medicine is assessed as rather low. The vast majority of the doctors expect clear improvements in patient medical care when the connection between gender and health are given more consideration.

Abstract
OBJECTIVE To compare anthroposophic treatment (eurythmy, rhythmical massage or art therapy; counselling, anthroposophic medication) and conventional treatment for low back pain (LBP) under routine conditions. METHODS 62 consecutive outpatients from 38 medical practices in Germany, consulting an anthroposophic (A-) or conventional (C-) physician with LBP of >or= 6 weeks duration participated in a prospective non-randomised comparative study. Main outcomes were Hanover Functional Ability Questionnaire (HFAQ), LBP Rating Scale Pain Score (LBPRS), Symptom Score, and SF-36 after 6 and 12 months. RESULTS At baseline, LBP duration was > 6 months in 85% (29/34) of A-patients and 54% (15/28) of C-patients (p = 0.004). Unadjusted analysis showed significant improvements in both groups of HFAQ, LBPRS, Symptom Score, SF-36 Physical Component Summary, and three SF-36 scales (Physical Function, Pain, Vitality), and improvements in A-patients of three further SF-36 scales (Role Physical, General Health, Mental Health). After adjustment for age, gender, LBP duration, and education, improvements were still significant in both groups for Symptom Score (p = 0.030), SF-36 Physical Component Summary (p = 0.004), and three SF-36-scales (Physical Function, p = 0.025; Role Physical, p = 0.014; Pain, p = 0.003), and in A-patients for SF-36-Vitality (p = 0.032). Compared to C-patients, A-patients had significantly more pronounced improvements of three SF-36 scales (Mental Health: p = 0.045; General Health: p = 0.006; Vitality: p = 0.005); other improvements did not differ significantly between the two groups. CONCLUSION Compared to conventional therapy, anthroposophic therapy for chronic LBP was associated with at least comparable improvements.

Abstract
OBJECTIVES To assess, over a period of 12 months, whether homoeopathic treatment could influence eczema signs/symptoms and quality of life (QoL) compared with conventional treatment. DESIGN Prospective multi-centre cohort study. SETTING Children with eczema aged 1-16 years were recruited from primary care practices. INTERVENTIONS Conventional versus homoeopathic treatment. OUTCOME MEASURES Patients (or parents) assessed eczema symptoms by numerical rating scales as well as disease-specific Atopie Lebensqualitaets-Fragebogen (ALF) and general quality of life (KINDL, KITA) at 0, 6 and 12 months. RESULTS A total of 118 children were included: 54 from homoeopathic (mean age+/-S.D. was 5.1+/-3.3 years; 56% boys) and 64 from conventional practices (6.2+/-3.8 years; 61% boys). Eczema symptoms (assessed by patients or their parents) improved from 0 to 12 months for both treatment options, but did not differ between the two groups: 3.5-2.5 versus 3.4-2.1; p=0.447 (adjusted). Disease-related quality of life improved in both groups similarly. In the subgroup of children aged 8-16 years the general quality of life showed a better trend for conventional treatment compared with homoeopathic treatment (p=0.030). CONCLUSIONS This observational study is the first long-term prospective investigation to compare homoeopathic and conventional treatment of eczema in children. Over a period of 12 months, both therapy groups improved similarly regarding perception of eczema symptoms (assessed by patients or parents) and disease-related quality of life.

Abstract
OBJECTIVES We investigated the effectiveness of homeopathic Arnica montana on postoperative swelling and pain after arthroscopy (ART), artificial knee joint implantation (AKJ), and cruciate ligament reconstruction (CLR). DESIGN Three randomised, placebo-controlled, double-blind, sequential clinical trials. SETTING Single primary care unit specialised in arthroscopic knee surgery. PARTICIPANTS Patients suffering from a knee disease that necessitated arthroscopic surgery. INTERVENTIONS Prior to surgery, patients were given 1 x 5 globules of the homeopathic dilution 30x (a homeopathic dilution of 1:10(30)) of arnica or placebo. Following surgery, 3 x 5 globules were administered daily. PRIMARY OUTCOME MEASURES The primary outcome parameter was difference in knee circumference, defined as the ratio of circumference on day 1 (ART) or day 2 (CLR and AKJ) after surgery to baseline circumference. RESULTS A total of 227 patients were enrolled in the ART (33% female, mean age 43.2 years;), 35 in the AKJ (71% female, 67.0 years), and 57 in the CLR trial (26% female; 33.4 years). The percentage of change in knee circumference was similar between the treatment groups for ART (group difference Delta=-0.25%, 95% CI: -0.85 to 0.41, p=0.204) and AKJ (Delta=-1.68%, -4.24 to 0.77, p=0.184) and showed homeopathic arnica to have a beneficial effect compared to placebo in CLR (Delta=-1.80%, -3.30 to -0.30, p=0.019). CONCLUSIONS In all three trials, patients receiving homeopathic arnica showed a trend towards less postoperative swelling compared to patients receiving placebo. However, a significant difference in favour of homeopathic arnica was only found in the CLR trial.

Abstract
In Germany, acupuncture is one of the most frequently used complementary and alternative therapies. In the year 2000, we initiated three large projects in co-operation with statutory health insurance companies to assess the effectiveness, safety and costs of acupuncture in patients with chronic headache, low back pain and pain due to osteoarthritis. Our findings showed that acupuncture was more effective than conventional standard treatment, treatment without acupuncture or a waiting list control. A significant difference between acupuncture and sham acupuncture was only seen for arthritis of the knee; for the other diagnoses, both forms of acupuncture showed similar effects. Whether the effects of acupuncture are due primarily to specific or unspecific mechanisms appears to depend on the diagnosis and should be investigated in further studies.

Abstract
OBJECTIVE The aim of this paper is to describe the treatment and physician characteristics in a randomised trial of acupuncture for osteoarthritis of the knee. DESIGN Three-armed, randomised, controlled multicentre trial with 1-year follow-up. SETTING Twenty-eight outpatient centres in Germany. INTERVENTIONS A total of 294 patients with osteoarthritis of the knee were randomised to 12 sessions of semi-standardised acupuncture (at least 6 local and 2 distant points needled per affected knee from a selection of predefined points, but individual choice of additional body or ear acupuncture points possible), 12 sessions of minimal acupuncture (superficial needling of at least 8 of 10 predefined, bilateral, distant non-acupuncture points) or a waiting list control (2 months no acupuncture). OUTCOME Participating trial physicians and interventions. RESULTS Forty-seven physicians specialised in acupuncture (mean age 43+/-8 years, 26 females) provided study interventions in 28 outpatient centres in Germany. The median duration of acupuncture training completed by participating physicians was 350 h (range 140-2508). The total number of needles used was 17.4+/-4.8 in the acupuncture group compared to 12.9+/-3.3 in the minimal acupuncture group. In total, 39 physicians (83%) stated that they would have treated patients in either a similar or in exactly the same way outside of the trial, whereas 7 (15%) stated that they would have treated patients differently (1 missing). CONCLUSIONS Our documentation of the trial interventions shows that semi-standardised acupuncture strategy represents an acceptable compromise for efficacy studies. However, a substantial minority of participating trial physicians stated that they would have treated patients differently outside of the trial.

Abstract
1. Voltage-dependent properties of isolated guinea pig outer hair cells (OHCs) were investigated using whole-cell recording. An inward current was detected in approximately 10% of the cells. This inward current was identified as belonging to the voltage-activated sodium current family on the basis of its high sensitivity to tetrodotoxin and the effect of substitution of impermeant ions. Although this is the first report of a sodium current in the mammalian cochlea, it differs from the classical neuronal sodium current by having a variable magnitude from cell to cell and an inactivation that is shifted to hyperpolarized potentials. The sensory processing role of hair cells in general and outer hair cells in particular could be disrupted by the presence of a regenerative voltage-dependent current. The functional role of the OHC sodium channels is puzzling, particularly as they may be silent in vivo.
