RESUMO
BACKGROUND: Intravascular lithotripsy (IVL) is a novel technique increasingly used for plaque modification and endovascular revascularization in patients with severe calcification and peripheral artery disease. However, much of the available literature on IVL is focused on its use in coronary arteries, with relatively limited data on non-coronary artery use. AIM: To analyze the safety and efficacy of current IVL use in non-coronary artery lesions, as reported in case reports and case series. METHODS: We searched EMBASE, PubMed, and Reference Citation Analysis databases for case reports and case series on IVL use in peripheral artery disease. We then extracted variables of interest and calculated the mean and proportions of these variables. RESULTS: We included 60 patients from 33 case reports/case series. Ninety-eight percent of the cases had IVL usage in only one blood vessel, while four had the IVL used in two vessels (2.0%), resulting in 64 Lesions treated with IVL. The mean age of the patients was 73.7 (SD 10.9). IVL was successfully used in severe iliofemoral artery stenosis (51.6%), severe innominate, subclavian, and carotid artery stenosis (26.7% combined), and severe mesenteric vessel stenosis (9.4%). Additionally, IVL was successfully used in severe renal (7.8%) and aortic artery (4.7%) stenosis. There were complications in 12% of the cases, with dissection being the commonest. CONCLUSION: IVL has successfully used in plaque modification and endovascular revascularization in severely calcified and challenging lesions in the iliofemoral, carotid, subclavian, aorta, renal, and mesenteric vessels. The most severe but transient complications were with IVL use in the aortic arch and neck arteries.
RESUMO
BACKGROUND: Home telemonitoring has been used as a modality to prevent readmission and improve outcomes for patients with heart failure. However, studies have produced conflicting outcomes over the years. AIM: To determine the aggregate effect of telemonitoring on all-cause mortality, heart failure-related mortality, all-cause hospitalization, and heart failure-related hospitalization in heart failure patients. METHODS: We conducted a systematic review and meta-analysis of 38 home telemonitoring randomized controlled trials involving 14993 patients. We also conducted a sensitivity analysis to examine the effect of telemonitoring duration, recent heart failure hospitalization, and age on telemonitoring outcomes. RESULTS: Our study demonstrated that home telemonitoring in heart failure patients was associated with reduced all-cause [relative risk (RR) = 0.83, 95% confidence interval (CI): 0.75-0.92, P = 0.001] and cardiovascular mortality (RR = 0.66, 95%CI: 0.54-0.81, P < 0.001). Additionally, telemonitoring decreased the all-cause hospitalization (RR = 0.87, 95%CI: 0.80-0.94, P = 0.002) but did not decrease heart failure-related hospitalization (RR = 0.88, 95%CI: 0.77-1.01, P = 0.066). However, prolonged home telemonitoring (12 mo or more) was associated with both decreased all-cause and heart failure hospitalization, unlike shorter duration (6 mo or less) telemonitoring. CONCLUSION: Home telemonitoring using digital/broadband/satellite/wireless or blue-tooth transmission of physiological data reduces all-cause and cardiovascular mortality in heart failure patients. In addition, prolonged telemonitoring (≥ 12 mo) reduces all-cause and heart failure-related hospitalization. The implication for practice is that hospitals considering telemonitoring to reduce heart failure readmission rates may need to plan for prolonged telemonitoring to see the effect they are looking for.
RESUMO
Pharmaceutical industry-led access programmes are increasing in number and scope worldwide. We present a new standardised framework for evaluation of these programmes that includes three components: a taxonomy of 11 access programme strategies; a series of logic models, one for each strategy and a set of measurement indicators. The logic models describe pathways of potential programme impact. Concepts relevant across a broad range of strategies were prioritised for inclusion in logic models to ensure consistency and to facilitate synthesis and learning across programmes. Each concept has at least one corresponding measurement indicator with metadata that includes the definition, details on how it should be measured and recommended data sources. The framework establishes a shared language for the collection and reporting of meaningful industry-led access programme information. Broad adoption by programme developers and implementing partners in the for-profit sector and beyond could facilitate shared learning on effective strategies and best practices.
RESUMO
CONTEXT: People living with human immunodeficiency virus (HIV) (PLWH) who are most at risk for falling out of HIV primary care and detectable viral loads include homeless and unstably housed individuals and those codiagnosed with behavioral health disorders. The patient-centered medical home (PCMH) is a model that promotes provision of comprehensive, patient-centered, accessible, coordinated, and quality care for patients. This initiative provided patient navigation to HIV-positive homeless and unstably housed individuals codiagnosed with a mental health or substance use disorder as a means to create an adapted PCMH to meet the specific needs of this population. OBJECTIVE: The purpose of this analysis was to characterize the roles and responsibilities of patient navigators as part of an effort to create a medical home for homeless and unstably housed PLWH with behavioral health comorbidities. DESIGN: Eighty-one in-depth interviews with clinic staff and 2 focus groups with patient navigators were conducted. Content analysis was performed to identify key roles and responsibilities of the patient navigators. RESULTS: Patient navigators played an important role in creating a PCMH by working with clients to schedule and complete appointments, develop comprehensive care plans, forging critical relationships with providers both within and outside of health care systems, providing holistic support to increase patient self-management, and assisting in achieving housing stability. CONCLUSIONS: It may be necessary to adapt the traditional PCMH model to effectively meet the social, behavior health, and medical needs of homeless and unstably housed PLWH with behavioral health comorbidities. A patient navigator who can invest time in supporting and connecting these patients to needed services may be a key component in creating an effective PCMH for this population. These findings highlight the roles and tasks of patient navigators that may contribute to developing a PCMH specific to homeless and unstably housed PLWH with mental health and substance use comorbidities. Implementation of such a model has the potential to improve health outcomes (such as retention in care and viral suppression) for particularly vulnerable PLWH and thereby reduce the burden of HIV infection.

Mobile "doctors" are traditional herbal medical practitioners who move from one rural community in Nigeria to another diagnosing disease using a digital thermometer and stethoscope before selling their herbal drugs to the patients. Are their diagnosis correct or just a deception? This reports looks at three cases of mobile doctors ' diagnosis of patients in rural southern Nigeria.

Introduction. Rubella infection has the potential of causing severe fetal birth defects collectively called congenital rubella syndrome (CRS) if the mother is infected early in pregnancy. However, little is known about rubella and CRS epidemiology in Nigeria and rubella vaccines are still not part of routine childhood immunization in Nigeria. Methods. Analysis of confirmed cases of rubella in Abia State, Nigeria from 2007 to 2011 detected through Abia State Integrated Disease Surveillance and Response system. Results. Of the 757 febrile rash cases, 81(10.7%) tested positive for rubella immunoglobulin M (IgM). New rubella infection decreased from 6.81/1,000,000 population in 2007 to 2.28/1,000,000 in 2009 and increased to 6.34/1,000,000 in 2011. The relative risk of rubella was 1.5 (CI [0.98-2.28]) times as high in females compared to males and 1.6 times (CI [0.90-2.91]) as high in rural areas compared to urban areas. Eighty six percent of rubella infections occurred in children less than 15 years with a high proportion of cases occurring between 5 and 14 years. Conclusion. Rubella infection in Abia State, Nigeria is predominantly in those who are younger than 15 years old. It is also more prevalent in females and in those living in rural areas of the state. Unfortunately, there is no surveillance of CRS in Nigeria and so the public health impact of rubella infection in the state is not known. Efforts should be made to expand the rubella surveillance in Nigeria to incorporate surveillance for CRS.
RESUMO
INTRODUCTION: Efforts at immunizing children against measles was intensified in Nigeria with nation-wide measles vaccination campaigns in 2005-2006, 2008 and 2011 targeting children between 9 and 59 months. However, there were measles outbreaks in 2010 and 2011 in Abia state Nigeria. This study seeks to find out if there is any association between measles immunization coverage and measles outbreak. METHODS: This is a descriptive analysis of the 2007 to 2011 Abia state measles case-based surveillance data supplied to Abia state World Health Organization office and Abia State Ministry of Health by the disease surveillance and notification officers. RESULTS: As the proportion of cases with febrile rash who were immunized decreased from 81% in 2007 to 42% in 2011, the laboratory confirmed cases of measles increased from two in 2007 to 53 in 2011.Of the laboratory confirmed cases of measles, five (7%) occurred in children < 9 months, 48 (64%) occurred in children 9-59 months and 22 (29%) occurred in children < 59 months old. Seventy five percent of all laboratory confirmed cases of measles occurred in rural areas. CONCLUSION: Efforts should be made to increase measles immunization in children between 9 and 59 months as most cases of measles occurred in this age group as immunization coverage dropped. In addition, further studies should be carried out to determine the cause of the disproportional incidence of measles in rural areas in Abia state bearing in mind that measles immunization coverage in urban and rural areas was not markedly different.
