Exercise therapy in adults with serious mental illness: a systematic review and meta-analysis

Background: Individuals with serious mental illness are at a higher risk of physical ill health. Mortality rates are at least twice those of the general population with higher levels of cardiovascular disease, metabolic disease, diabetes, and respiratory illness. Although genetics may have a role in the physical health problems of these patients, lifestyle and environmental factors such as levels of smoking, obesity, poor diet, and low levels of physical activity also play a prominent part.<p></p> Objective: To conduct a systematic review and meta-analysis of randomised controlled trials comparing the effect of exercise interventions on individuals with serious mental illness.<p></p> Methods: Searches were made in Ovid MEDLINE, Embase, CINAHL, PsycINFO, Biological Abstracts on Ovid, and The Cochrane Library (January 2009, repeated January 2013) through to February 2013.<p></p> Results: Eight RCTs were identified in the systematic search. Six compared exercise versus usual care. One study assessed the effect of a cycling programme versus muscle strengthening and toning exercises. The final study compared the effect of adding specific exercise advice and motivational skills to a simple walking programme. Exercise programmes were noted by their heterogeneity in terms of the type of exercise intervention, setting, and outcome measures. The review found that exercise improved levels of exercise activity (n=13, standard mean difference [SMD] 1.81, CI 0.44 to 3.18, p = 0.01). No beneficial effect was found on negative (n = 84, SMD = -0.54, CI -1.79 to 0.71, p = 0.40) or positive symptoms of schizophrenia (n = 84, SMD = -1.66, CI -3.78 to 0.45, p = 0.12). No change was found on body mass index compared with usual care (n= 151, SMD = -0.24, CI -0.56 to 0.08, p = 0.14), or body weight (n = 77, SMD = 0.13, CI -0.32 to 0.58, p = 0.57). No beneficial effect was found on anxiety and depressive symptoms (n = 94, SMD = -0.26, CI -0.91 to 0.39, p = 0.43), or quality of life in respect of physical and mental domains. One RCT measured the effect of exercise on exercise intensity, attendance, and persistence at a programme. No significant effect was found on these measures.<p></p> Conclusions: This systematic review showed that exercise therapies can lead to a modest increase in levels of exercise activity but overall there was no noticeable change for symptoms of mental health, body mass index, and body weight.<p></p&gt

Vascular disrupting action of electroporation and electrochemotherapy with bleomycin in murine sarcoma

Electrochemotherapy has a direct cytotoxic effect on tumour cells, and presumably, a vascular disrupting effect. In this study, on the basis of the prediction of the mathematical model, histological evaluation and physiological measurements of the tumours were carried out to confirm that electroporation and electrochemotherapy of tumours have a vascular disrupting action. In the study, SA-1 solid subcutaneous sarcoma tumours in A/J mice were treated by bleomycin (BLM) given intravenously (1 mg kg−1), application of electric pulses (8 pulses, 1040 V, 100 μs, 1 Hz) or a combination of both – electrochemotherapy. The vascular effect was determined by laser Doppler flowmetry, power Doppler ultrasonographic imaging and Patent blue staining. The extent of tumour hypoxia was determined immunohistochemically by hypoxia marker pimonidazole and partial pressure of oxygen (pO2) in tumours by electron paramagnetic resonance oximetry. Electrochemotherapy with BLM induced good antitumour effect with 22 days, tumour growth delay and 38% tumour cures. The application of electric pulses to the tumours induced instant but transient tumour blood flow reduction (for 70%) that was recovered in 24 h. During this tumour blood flow reduction, we determined an increase in hypoxic tumour area for up to 30%, which was also reflected in reduced tumour oxygenation (for 70%). According to the described mathematical model, endothelial cells lining in tumour blood vessels are exposed to a ∼40% higher electric field than the surrounding tumour cells, and therefore easily electroporated, allowing access of high BLM concentration to the cytosol. Consequently, electrochemotherapy has, besides the immediate vascular disrupting action, also a delayed one (after 24 h), as a consequence of endothelial cell swelling and apoptosis demonstrated by extensive tumour necrosis, tumour hypoxia, prolonged reduction of tumour blood flow and significant tumour growth delay, and tumour cures. Our results demonstrate that in addition to the well-established direct cytotoxic effect on tumour cells, electrochemotherapy also has an indirect vascular disrupting action resulting altogether in extensive tumour cell necrosis leading to complete regression of tumours

Community-based post-stroke service provision and challenges: a national survey of managers and inter-disciplinary healthcare staff in Ireland

<p>Abstract</p> <p>Background</p> <p>The extent of stroke-related disability typically becomes most apparent after patient discharge to the community. As part of the Irish National Audit of Stroke Care (INASC), a national survey of community-based allied health professionals and public health nurses was conducted. The aim was to document the challenges to service availability for patients with stroke in the community and to identify priorities for service improvement.</p> <p>Methods</p> <p>The study was a cross-sectional tailored interview survey with key managerial and service delivery staff. As comprehensive listings of community-based health professionals involved in stroke care were not available, a cascade approach to information gathering was adopted. Representative regional managers for services incorporating stroke care (N = 7) and disciplinary allied health professional and public health nurse managers (N = 25) were interviewed (94% response rate).</p> <p>Results</p> <p>Results indicated a lack of formal, structured community-based services for stroke, with no designated clinical posts for stroke care across disciplines nationally. There was significant regional variation in availability of allied health professionals. Considerable inequity was identified in patient access to stroke services, with greater access, where available, for older patients (≥ 65 years). The absence of a stroke strategy and stroke prevalence statistics were identified as significant impediments to service planning, alongside organisational barriers limiting the recruitment of additional allied health professional staff, and lack of sharing of discipline-specific information on patients.</p> <p>Conclusions</p> <p>This study highlighted major gaps in the provision of inter-disciplinary team community-based services for people with stroke in one country. Where services existed, they were generic in nature, rarely inter-disciplinary in function and deficient in input from salient disciplines. Challenges to optimal care included the need for strategic planning; increased funding of healthcare staff; increased team resources and teamwork; and removal of service provision barriers based on age. There were notably many challenges beyond funding. Similar evaluations in other healthcare systems would serve to provide comparative lessons to serve to tackle this underserved aspect of care for patients with stroke and their families.</p
