Therapeutic Massage Combined with Mirror Therapy for Phantom Limb Pain: Two Experimental Cases

poster abstractPhantom limb pain (PLP) is a common and difficult to treat issue for individuals with amputations. Current PLP treatments (primarily pharmaceutical) are only modestly effective and often have negative side-effects. Massage has been self-reported as beneficial for PLP but no research has examined massage specifically for PLP. Mirror therapy’s evidence base for PLP is building. Combining massage (which alone may impact PLP via Pfleger’s law of symmetry) with mirror therapy may allow practitioners to apply massage for a painful area that cannot actually be touched. The current quasi-experimental A-B-A withdrawal case series sought to descriptively examine outcomes of therapeutic massage combined with mirror therapy (TMwMT) for individuals with persistent lower limb PLP and establish feasibility of intervention delivery. Each study phase was four weeks long with bi-weekly, individualized 20-25 minute TMwMT sessions during the treatment (B) phase. TMwMT sessions were developed and applied to address the specific participant PLP experience as if the pain were experienced by the intact limb. During masked TMwMT sessions, participants viewed a real-time mirror image of their intact leg receiving massage in the place of their missing limb. Measures: bi-weekly PLP severity via VAS; PLP intensity and interference collected at beginning/end of each phase via Brief Pain Inventory. Two men completed the study protocol. PLP severity decreased during treatment for both participants with effects beginning to diminish by week two of the withdrawal phase. By the study’s conclusion, PLP severity had not elevated back to average levels of initial phase A. Pain intensity for both participants improved during phase B but results were mixed for pain interference. These individuals had not responded to previous treatments for their PLP; our experimental, non-pharmacological and targeted TMwMT treatment was beneficial in the short-term. Our intervention is theoretically sound, reflects aspects of real-world massage delivery, and needs further investigation

A new species of Polemanniopsis (Apiaceae) from Namibia

AbstractA new species of woody Apiaceae, Polemanniopsis namibensis B-E. Van Wyk, A. Burke & C. Mannheimer, is described. The species is allied to Polemanniopsis marlothii but differs in the much smaller habit of (up to 0.6m vs 1.5–4m in Polemanniopsis marlothii), the white or greyish colour of the twigs (brown in Polemanniopsis marlothii), the 3-foliolate leaves (predominantly 5-foliate in Polemanniopsis marlothii), the smaller inflorescences with persistent involucral bracts (caducous in Polemanniopsis marlothii) and anatomical details of the leaves. The species is endemic to Namibia and is known only from a localised area in the southern Namib desert near Lüderitz, where it is relatively common

Multidrug-Resistant Tuberculosis in Patients without HIV Infection

BACKGROUND Investigations of outbreaks of multidrug-resistant tuberculosis have found low rates of treatment response and very high mortality, and they have mainly involved patients with advanced human immunodeficiency virus (HIV) infection. For patients without HIV infection, one study reported an overall rate of response to treatment of 56 percent, and the mortality from tuberculosis was 22 percent. We investigated treatment response and mortality rates in 26 HIV-negative patients in New York with multidrug-resistant tuberculosis. METHODS We obtained detailed data from seven teaching hospitals in New York City on patients with multidrug-resistant tuberculosis--defined as tuberculosis resistant at least to isoniazid and rifampin--who were HIV-negative on serologic testing. Lengths of times from diagnosis to the initiation of appropriate therapy and from the initiation of appropriate therapy to conversion to negative cultures were assessed. Therapeutic responses were evaluated by both microbiologic and clinical criteria. RESULTS Between March 1991 and September 1994, 26 HIV-negative patients were identified and treated. Of the 25 patients for whom adequate data were available for analysis, 24 (96 percent) had clinical responses; all 17 patients for whom data on microbiologic response were available had such a response. The median times from diagnosis to the initiation of appropriate therapy and from the initiation of therapy to culture conversion were 44 days (range, 0 to 181) and 69 days (range, 2 to 705), respectively. Side effects requiring the discontinuation of medication occurred in 4 of 23 patients (17 percent) who were treated with second-line antituberculosis medications. The median follow-up for the 23 patients who responded and who received appropriate therapy was 91 weeks (range, 41 to 225). CONCLUSIONS In this report from New York City, HIV-negative patients with multidrug-resistant tuberculosis, contrary to previous reports, responded well to appropriate chemotherapy, both clinically and microbiologically

The effect of electrical neurostimulation on collateral perfusion during acute coronary occlusion

<p>Abstract</p> <p>Background</p> <p>Electrical neurostimulation can be used to treat patients with refractory angina, it reduces angina and ischemia. Previous data have suggested that electrical neurostimulation may alleviate myocardial ischaemia through increased collateral perfusion. We investigated the effect of electrical neurostimulation on functional collateral perfusion, assessed by distal coronary pressure measurement during acute coronary occlusion. We sought to study the effect of electrical neurostimulation on collateral perfusion.</p> <p>Methods</p> <p>Sixty patients with stable angina and significant coronary artery disease planned for elective percutaneous coronary intervention were split in two groups. In all patients two balloon inflations of 60 seconds were performed, the first for balloon dilatation of the lesion (first episode), the second for stent delivery (second episode). The Pw/Pa ratio (wedge pressure/aortic pressure) was measured during both ischaemic episodes. Group 1 received 5 minutes of active neurostimulation before plus 1 minute during the first episode, group 2 received 5 minutes of active neurostimulation before plus 1 minute during the second episode.</p> <p>Results</p> <p>In group 1 the Pw/Pa ratio decreased by 10 ± 22% from 0.20 ± 0.09 to 0.19 ± 0.09 (p = 0.004) when electrical neurostimulation was deactivated. In group 2 the Pw/Pa ratio increased by 9 ± 15% from 0.22 ± 0.09 to 0.24 ± 0.10 (p = 0.001) when electrical neurostimulation was activated.</p> <p>Conclusion</p> <p>Electrical neurostimulation induces a significant improvement in the Pw/Pa ratio during acute coronary occlusion.</p

Spinal cord stimulation in the treatment of refractory angina: systematic review and meta-analysis of randomised controlled trials

<p>Abstract</p> <p>Background</p> <p>The aim of this paper was undertake a systematic review and meta-analysis of the use of spinal cord stimulation (SCS) in the management of refractory angina.</p> <p>Methods</p> <p>We searched a number of electronic databases including Medline, Embase and Cochrane Library up to February 2008 to identify randomised controlled trials (RCTs) reporting exercise capacity, ischemic burden, functional class, quality of life, usage of anti-anginal medication, costs and adverse events including mortality. Results were reported both descriptively for each study and using random effects meta-analysis. Given the variety in outcomes reported, some outcome results were pooled as standardised mean differences (SMD) and reported in standard deviation units.</p> <p>Results</p> <p>Seven RCTs were identified in a total of 270 refractory angina patients. The outcomes of SCS were found to be similar when directly compared to coronary artery bypass grafting (CABG) and percutaneous myocardial laser revascularisation (PMR). Compared to a 'no stimulation' control, there was some evidence of improvement in all outcomes following SCS implantation with significant gains observed in pooled exercise capacity (SMD: 0.76, 0.07 to 1.46, <it>p </it>= 0.03) and health-related quality of life (SMD: 0.83, 95% CI: 0.32 to 1.34, <it>p </it>= 0.001). Trials were small and were judged to range considerably in their quality. The healthcare costs of SCS appeared to be lower than CABG at 2-years follow up.</p> <p>Conclusion</p> <p>SCS appears to be an effective and safe treatment option in the management of refractory angina patients and of similar efficacy and safety to PMR, a potential alternative treatment. Further high quality RCT and cost effectiveness evidence is needed before SCS can be accepted as a routine treatment for refractory angina.</p

Retention Strategies and Factors Associated with Missed Visits Among Low Income Women at Increased Risk of HIV Acquisition in the US (HPTN 064)

Women at high-risk for HIV acquisition often face challenges that hinder their retention in HIV prevention trials. These same challenges may contribute to missed clinical care visits among HIV-infected women. This article, informed by the Gelberg-Andersen Behavioral Model for Vulnerable Populations, identifies factors associated with missed study visits and describes the multifaceted retention strategies used by study sites. HPTN 064 was a multisite, longitudinal HIV seroincidence study in 10 US communities. Eligible women were aged 18–44 years, resided in a census tract/zipcode with high poverty and HIV prevalence, and self-reported ≥1 personal or sex partner behavior related to HIV acquisition. Multivariate analyses of predisposing (e.g., substance use) and enabling (e.g., unmet health care needs) characteristics, and study attributes (i.e., recruitment venue, time of enrollment) identified factors associated with missed study visits. Retention strategies included: community engagement; interpersonal relationship building; reduction of external barriers; staff capacity building; and external tracing. Visit completion was 93% and 94% at 6 and 12 months. Unstable housing and later date of enrollment were associated with increased likelihood of missed study visits. Black race, recruitment from an outdoor venue, and financial responsibility for children were associated with greater likelihood of attendance. Multifaceted retention strategies may reduce missed study visits. Knowledge of factors associated with missed visits may help to focus efforts

Daily and Nondaily Oral Preexposure Prophylaxis in Men and Transgender Women Who Have Sex With Men: The Human Immunodeficiency Virus Prevention Trials Network 067/ADAPT Study

Background: Nondaily dosing of oral preexposure prophylaxis (PrEP) may provide equivalent coverage of sex events compared with daily dosing. Methods: At-risk men and transgender women who have sex with men were randomly assigned to 1 of 3 dosing regimens: 1 tablet daily, 1 tablet twice weekly with a postsex dose (time-driven), or 1 tablet before and after sex (event-driven), and were followed for coverage of sex events with pre- and postsex dosing measured by weekly self-report, drug concentrations, and electronic drug monitoring. Results: From July 2012 to May 2014, 357 participants were randomized. In Bangkok, the coverage of sex events was 85% for the daily arm compared with 84% for the time-driven arm (P = .79) and 74% for the event-driven arm (P = .02). In Harlem, coverage was 66%, 47% (P = .01), and 52% (P = .01) for these groups. In Bangkok, PrEP medication concentrations in blood were consistent with use of ≥2 tablets per week in >95% of visits when sex was reported in the prior week, while in Harlem, such medication concentrations occurred in 48.5% in the daily arm, 30.9% in the time-driven arm, and 16.7% in the event-driven arm (P < .0001). Creatinine elevations were more common in the daily arm (P = .050), although they were not dose limiting. Conclusions: Daily dosing recommendations increased coverage and protective drug concentrations in the Harlem cohort, while daily and nondaily regimens led to comparably favorable outcomes in Bangkok, where participants had higher levels of education and employment

An analysis of ophthalmology services in Finland - has the time come for a Public-Private Partnership?

<p>Abstract</p> <p>Background</p> <p>We studied the prerequisites for Public-Private Partnership (PPP) in the context of the Finnish health care system and more specifically in the field of ophthalmology. PPP can be defined as a more or less permanent cooperation between public and private actors, through which the joint products or services are developed and in which the risks, costs and profits are shared.</p> <p>The Finnish eye care services system is heterogeneous with several different providers and can be regarded as sub-optimal in terms of overall resource use. What is more, the public sector is suffering from a shortage of ophthalmologists, which further decreases its possibilities to meet the present needs. As ophthalmology has traditionally been a medical specialty with a substantial private sector involvement in service provision, PPP could be a feasible policy to be used in the field. We thus ask the following research question: Is there, and to what extent, an open window of opportunity for PPP?</p> <p>Methods</p> <p>In addition to the previously published literature, the research data consisted of 17 thematic interviews with public and private experts in the field of ophthalmology. The analysis was conducted in two stages. First, a literature-based content analysis was used to explore the prerequisites for PPP. Second, Kingdon's (1995) multiple streams theory was used to study the opening of the window of opportunity for PPP.</p> <p>Results</p> <p>Public and private parties reported similar problems in the current situation but defined them differently. Also, there is no consensus on policy alternatives. Public opinion seems to be somewhat uncertain as to the attitudes towards private service providers. The analysis thus showed that although there are prerequisites for PPP, the time has not yet come for a Public-Private Partnership.</p> <p>Conclusion</p> <p>Should the window open fully, the emergence of policy entrepreneurs and an opportunity for a win-win situation between public and private organizations are required.</p
