- ItemOpen AccessClosing the treatment gap for mental, neurological and substance use disorders by strengthening existing health care platforms: strategies for delivery and integration of evidence-based interventions(2015) Shidhaye, Rahul; Lund, Crick; Chisholm, DanThis paper outlines the main elements and features of a mental health care delivery platform and its delivery channels. These include evidence-based interventions that can be delivered via this platform as well as broader health system strengthening strategies for more effective and efficient delivery of services. The focus is broadly on health systems perspective rather than strictly disorder-oriented intervention analysis. A set of evidence-based interventions within the WHO pyramid framework of self-care, primary care, and specialist care have been identified; the main challenge lies in the translation of that evidence into practice. The delivery of these interventions requires an approach that puts into practice key principles of public health, adopts systems thinking, promotes whole-of-government involvement and is focused on quality improvement. Key strategies for effective translation of evidence into action include collaborative stepped care, strengthening human resources, and integrating mental health into general health care. In order to pursue these principles and strategies using a platform-wide approach, policy makers need to engage with a wide range of stakeholders and make use of the best available evidence in a transparent manner.
- ItemOpen AccessPregabalin for the treatment of generalized anxiety disorder: an update(2013) Baldwin, David S; Ajel, Khalil; Masdrakis, Vasilios G; Nowak, Magda; Rafiq, RizwanA previous review summarized what was then known about the potential role of pregabalin in the treatment of patients with generalized anxiety disorder (GAD): this review provides an update on its pharmacological properties and presumed mechanism of action, the liability for abuse, and efficacy and tolerability in patients with GAD. Pregabalin has a similar molecular structure to the inhibitory neurotransmitter gamma amino butyric acid (GABA) but its mechanism of action does not appear to be mediated through effects on GABA. Instead, its anxiolytic effects may arise through high-affinity binding to the alpha-2-delta sub-unit of the P/Q type voltage-gated calcium channel in “over-excited” presynaptic neurons, thereby reducing the release of excitatory neurotransmitters such as glutamate. The findings of randomized controlled trials and meta-analyses together indicate that pregabalin is efficacious in both acute treatment and relapse prevention in GAD, with some evidence of an early onset of effect, and broad efficacy in reducing the severity of psychological and physical symptoms of anxiety. It also has efficacy as an augmenting agent after non-response to antidepressant treatment in GAD. Continuing vigilance is needed in assessing its potential abuse liability but the tolerability profile of pregabalin may confer some advantages over other pharmacological treatments in the short term for treatment in patients with GAD.
- ItemOpen AccessThe association between HIV and atherosclerotic cardiovascular disease in sub-Saharan Africa: a systematic review(BioMed Central, 2017-12-15) Hyle, Emily P; Mayosi, Bongani M; Middelkoop, Keren; Mosepele, Mosepele; Martey, Emily B; Walensky, Rochelle P; Bekker, Linda-Gail; Triant, Virginia Aackground: Sub-Saharan Africa (SSA) has confronted decades of the HIV epidemic with substantial improvements in access to life-saving antiretroviral therapy (ART). Now, with improved survival, people living with HIV (PLWH) are at increased risk for non-communicable diseases (NCDs), including atherosclerotic cardiovascular disease (CVD). We assessed the existing literature regarding the association of CVD outcomes and HIV in SSA. Methods: We used the PRISMA guidelines to perform a systematic review of the published literature regarding the association of CVD and HIV in SSA with a focus on CVD surrogate and clinical outcomes in PLWH. Results: From January 2000 until March 2017, 31 articles were published regarding CVD outcomes among PLWH in SSA. Data from surrogate CVD outcomes (n = 13) suggest an increased risk of CVD events among PLWH in SSA. Although acute coronary syndrome is reported infrequently in SSA among PLWH, limited data from five studies suggest extensive thrombus and hypercoagulability as contributing factors. Additional studies suggest an increased risk of stroke among PLWH (n = 13); however, most data are from immunosuppressed ART-naïve PLWH and thus are potentially confounded by the possibility of central nervous system infections. Conclusions: Given ongoing gaps in our current understanding of CVD and other NCDs in PLWH in SSA, it is imperative to ascertain the burden of CVD outcomes, and to examine strategies for intervention and best practices to enhance the health of this vulnerable population.
