Disease-specific Interventions Research Articles

Update on cardiovascular prevention in clinical practice: A position paper of the European Association of Preventive Cardiology of the European Society of Cardiology.

European guidelines on cardiovascular prevention in clinical practice were first published in 1994 and have been regularly updated, most recently in 2016, by the Sixth European Joint Task Force. Given the amount of new information that has become available since then, components from the task force and experts from the European Association of Preventive Cardiology of the European Society of Cardiology were invited to provide a summary and critical review of the most important new studies and evidence since the latest guidelines were published. The structure of the document follows that of the previous document and has six parts: Introduction (epidemiology and cost effectiveness); Cardiovascular risk; How to intervene at the population level; How to intervene at the individual level; Disease-specific interventions; and Settings: where to intervene? In fact, in keeping with the guidelines, greater emphasis has been put on a population-based approach and on disease-specific interventions, avoiding re-interpretation of information already and previously considered. Finally, the presence of several gaps in the knowledge is highlighted.

Acceptability and utilization of evidence for decision-making: helminth control, sub-Saharan Africa

Abstract Background Public health practitioners are part of a larger global health system, responsible for the implementation of disease-specific health interventions, largely financed by external actors through a variety of mechanisms. Emphasis on the need for evidence-informed decision-making often includes rhetoric for the localization of this approach to assist practitioners in resource allocation. In practice its realisation is challenging. This research addresses the following: what are the evidence needs of local public health practitioners? How acceptable are, for example, modeled disease estimates? What decision-making processes occur for implementation? How do evidence and decision-making processes interact? Methods Examining mass drug administration (MDA) for schistosomiasis and soil-transmitted helminths (STH) in the African Great Lakes region (Kenya, Malawi, Tanzania and Uganda), we use qualitative approaches to collect data, including a series of 4 workshops with district- and national-level MoH personnel, key informant interviews and e-survey questionnaires from a sample of relevant local and global organisations including NGOs. Coded data are analysed thematically. Results Preliminary results provide important insights into the sources, types and format of evidence which local public health practitioners find acceptable and useful for decision-making when implementing disease control measures. Conclusions A variety of factors influence local level decision-making with implications for policy aimed at disease control, such as MDA for schistosomiasis and STH, and global health policy and practice more broadly. First, processes of decision-making at different localities are heterogenous and evidence needs of local practitioners are not well understood. Second, evidence development and knowledge synthesis on health interventions are rarely linked in ways that feedback and respond to local implementation, decision-making practices and public health practitioners. Key messages Evidence needs of local public health practitioners need to be accounted for when producing and synthesising evidence. Multiple factors influence local level decision-making with implications for public health disease control policy.

Quantifying Positive Health Externalities of Disease Control Interventions: Modeling Chikungunya and Dengue.

Purpose. Health interventions can generate positive externalities not captured in traditional, single-disease cost-effectiveness analyses (CEAs), potentially biasing results. We illustrate this with the example of mosquito-borne diseases. When a particular mosquito species can transmit multiple diseases, a single-disease CEA comparing disease-specific interventions (e.g., vaccination) with interventions targeting the mosquito population (e.g., insecticide) would underestimate the insecticide's full benefits (i.e., preventing other diseases). Methods. We developed three dynamic transmission models: chikungunya, dengue, and combined chikungunya and dengue, each calibrated to disease-specific incidence and deaths in Colombia (June 2014 to December 2017). We compared the models' predictions of the incremental benefits and cost-effectiveness of an insecticide (10% efficacy), hypothetical chikungunya and dengue vaccines (40% coverage, 95% efficacy), and combinations of these interventions. Results. Model calibration yielded realistic parameters that produced close matches to disease-specific incidence and deaths. The chikungunya model predicted that vaccine would decrease the incidence of chikungunya and avert more total deaths than insecticide. The dengue model predicted that insecticide and the dengue vaccine would reduce dengue incidence and deaths, with no effect for the chikungunya vaccine. In the combined model, insecticide was more effective than either vaccine in reducing the incidence of and deaths from both diseases. In all models, the combined strategy was at least as effective as the most effective single strategy. In an illustrative CEA, the most frequently preferred strategy was vaccine in the chikungunya model, the status quo in the dengue model, and insecticide in the combined model. Limitations. There is uncertainty in the target calibration data. Conclusions. Failure to capture positive externalities can bias CEA results, especially when evaluating interventions that affect multiple diseases. Multidisease modeling is a reasonable alternative for addressing such biases.

A descriptive analysis of the Spatio-temporal distribution of intestinal infectious diseases in China

BackgroundIntestinal infectious diseases (IIDs) have caused numerous deaths worldwide, particularly among children. In China, eight IIDs are listed as notifiable infectious diseases, including cholera, poliomyelitis, dysentery, typhoid and paratyphoid (TAP), viral Hepatitis A, viral Hepatitis E, hand-foot-mouth disease (HFMD) and other infectious diarrhoeal diseases (OIDDs). The aim of the study is to analyse the spatio-temporal distribution of IIDs from 2006 to 2016.MethodsData on the incidence of IIDs from 2006 to 2016 were collected from the public health science data centre issued by the Chinese Center for Disease Control and Prevention. This study applied seasonal decomposition analysis, spatial autocorrelation analysis and space-time scan analysis. Plots and maps were constructed to visualize the spatio-temporal distribution of IIDs.ResultsRegarding temporal analysis, the incidence of HFMD and Hepatitis E showed a distinct increasing trend, while the incidence of TAP, dysentery, and Hepatitis A presented decreasing trends over the last decade. The incidence of OIID remained steady. Summer is the season with the greatest number of cases of different IIDs. Regarding the spatial distribution, approximately all p values for the global Moran’s I from 2006 to 2016 were less than 0.05, indicating that the incidences of the epidemics were unevenly distributed throughout the country. The high-risk areas for HFMD and OIDD were located in the Beijing-Tianjin-Tangshan (BTT) region and south China. The high-risk areas for TAP were located in some parts of southwest China. A higher incidence rates for dysentery and Hepatitis A were observed in the BTT region and some west provincial units. The high-risk areas for Hepatitis E were the BTT region and the Yangtze River Delta area.ConclusionsBased on our temporal and spatial analysis of IIDs, we identified the high-risk periods and clusters of regions for the diseases. HFMD and OIDD exhibited high incidence rates, which reflected the negligence of Class C diseases by the government. At the same time, the incidence rate of Hepatitis E gradually surpassed Hepatitis A. The authorities should pay more attention to Class C diseases and Hepatitis E. Regardless of the various distribution patterns of IIDs, disease-specific, location-specific, and disease-combined interventions should be established.

Adherence to medication in neurogeriatric patients: an observational cross-sectional study

BackgroundPoor adherence is a major issue and is associated with increased morbidity, mortality, and immense costs for the healthcare system. Due to demographic changes, the burden of neurological diseases is increasing with a crucial exacerbation of the problem of nonadherence. However, comprehensive data on geriatric patients with neurological disorders do not exist to date. In this cross-sectional observational study we aim to identify disease-specific adherence-modulating factors in neurogeriatric patients.MethodsPatients 60 years or older with neurological disorders will receive an assessment of adherence (Stendal Adherence with Medication Score) and a comprehensive geriatric assessment during their stay in the Department of Neurology or Geriatrics at the Jena University Hospital (baseline data). In addition disease specific data will be derived from medical records. After one and twelve months a telephone interview will be conducted to evaluate if and why changes of medication occurred (follow up data).DiscussionThis study aims to explore disease-specific patterns of nonadherence in elderly patients with neurological disorders and characteristics of information transfer between a specialized center, practicing neurologists, general practitioners, and the patients and their caregivers. This comprehensive data may help to develop and apply complex and disease-specific interventions to enhance adherence.Trial registrationGerman Clinical Trials Register DRKS00016774.

A systematic review of mobile health interventions in China: Identifying gaps in care

Introduction Mobile health has a promising future in the healthcare system in most developed countries. China’s rapidly developing mobile technology infrastructure offers an unprecedented opportunity for wide adoption of mobile health interventions in the delivery of effective and timely healthcare services. However, there is little data on the current extent of the mobile health landscape in China. The aim of this study was to systematically review the existing mobile health initiatives in China, characterise the technology used, disease categories targeted, location of the end user (urban versus rural), and examine the potential effects of mobile health on health system strengthening in China. Furthermore, we identified gaps in development and evaluation of the effectiveness of mobile health interventions. Methods A systematic review of the literature published from 18 December 2015 – 3 April 2019 was conducted and yielded 2863 articles from English and Chinese retrieval database and trial registries, including PubMed, EMBASE, China National Knowledge of Infrastructure and World Health Organization International Clinical Trials Registry Platform. Studies were included if they used mobile health to support patient healthcare outcomes. Results A total of 1129 full-text articles were assessed and 338 were included in this study. The review found that most studies targeted client education and behaviour change via applications (apps) (65.4%), including WeChat, and text messaging (short text messages) (19.8%) to improve patient medical treatment outcomes such as compliance and appointment reminders. The most common disease-specific mobile health interventions focused primarily on chronic disease management and behaviour change in cardiology (13.3%), endocrinology/diabetes (12.1%), behavioural health (11.8%), oncology (11.2%) and neurology (6.8%). The mobile health interventions related to nutrition (0.6%) and chronic respiratory diseases (1.6%) are underrepresented in mobile health in comparison to the burden of disease in China. The majority (90.0%) of the mobile health interventions were conducted exclusively in urban areas, with few opportunities reaching rural populations. Conclusions Overall, mobile health has a promising future in China, with recent rapid growth in initiatives. The majority are focused on education and behaviour change in the realm of chronic diseases and target patients in urban areas. The imbalance in mobile health between the urban and rural areas, as well as between population disease spectrum and health service delivery, pose substantial dilemmas. However, mobile health may be redirected to correct this imbalance, possibly improving access to healthcare services, and filling the gaps in order to improve health equity for the underserved populations in China.

A case of cutaneous metastatic adenosquamous carcinoma of the cervix

Introduction:Cutaneous metastasis of cervical carcinoma is very rare, with a reported incidence of .1 to 2%. The adenosquamous carcinoma subtype has been reported the least.3-5 We present a case report of ulceronodular cutaneous metastasis of adenosquamous carcinoma of the cervix.Case Description:A 50-year-old African American female with an eleven-year history of metastatic adenosquamous carcinoma of the cervix presented to the emergency department with an asymptomatic rash in her groin for one-month duration. On physical exam, there were hyperpigmented to violaceous papulonodules across the mons pubis and three ulcerated plaques of the left mons pubis. Punch biopsy was consistent with metastases of cervical adenosquamous carcinoma. No disease specific interventions were taken, and the patient passed away five weeks later.Discussion:Cervical cancer rarely metastasizes to the skin, with a reported incidence of .1 to 2%. Among the subtypes, cutaneous metastasis of cervical adenosquamous carcinoma has been reported the least. In a review of 1185 cases of cervical cancer, Imachi et al found that only 15 cases spread cutaneously, none of which were adenosquamous carcinoma.5 Cutaneous metastases of cervical carcinoma predict a poor prognosis, with an average length of survival of three months.6Our patient developed cutaneous metastases eleven years after diagnosis, which is to our knowledge the longest reported interval from initial diagnosis to development of cutaneous metastases. Although rare, it is important to recognize cutaneous metastases of adenosquamous carcinoma of the cervix as it predicts a poor prognosis and treatment has not been shown to improve outcomes.

Long‐term cardiovascular outcome of Williams syndrome

Cardiovascular lesions are the leading cause of morbidity and mortality in patients with Williams syndrome. Recent studies have rebutted conventional reports about the natural course of cardiovascular anomalies in Williams syndrome. Retrospective study. Single tertiary center. Eighty patients with Williams syndrome followed up for more than 5 years. Not applicable. Long-term outcome of cardiovascular lesions, peak velocity change in obstructive cardiovascular lesions over time, post-interventional courses of disease-specific intervention, and intervention-free survival of obstructive cardiovascular lesions. The median follow-up duration was 11.0 (5.1-28.3) years. Among 80 patients, supravalvular aortic stenosis (87.5%) was the most common cardiovascular lesion, followed by branch pulmonary stenosis (53.8%), mitral valve prolapse (22.5%), and aortic arch hypoplasia/coarctation (5.0%). During the follow-up period, the peak flow velocity of supravalvular aortic stenosis did not change on peak Doppler echocardiography. Initially, severe supravalvular aortic stenosis was aggravated (P<.027). Conversely, the peak velocity of branch pulmonary stenosis decreased (from 3.08 to 1.65 m/s; P<.001) within age 3.2 (0.4-6.9) years. Even the group with severe branch PS improved over time. Twenty-two patients (27.5%) with Williams syndrome underwent disease-specific interventions without mortality, mostly for supravalvular aortic stenosis or mitral valve prolapse. No patient in the late-onset and initially mild supravalvular aortic stenosis group needed intervention and 37.5%, 48.4%, and 65.1% in initially moderate and severe supravalvular aortic stenosis groups needed intervention at age 5, 10, and 20 years, respectively. Unlike the conventional therapeutic concept, the intervention for branch pulmonary stenosis was almost unnecessary. In Williams syndrome, initially severe supravalvular aortic stenosis worsened over time and most branch pulmonary stenoses, including those in the severe group, improved spontaneously. Most patients with branch pulmonary stenosis did not require disease-specific intervention. Surgical repairs for cardiovascular abnormalities in Williams syndrome showed favorable results.

Tackling Patient-Reported Outcomes in Atrial Fibrillation and Heart Failure: Identifying Disease-Specific Symptoms?

Atrial fibrillation (AF) and heart failure (HF) both significantly affect morbidity and mortality and also account for high symptom burden and impaired health-related quality of life (hrQoL). Several well-designed and broadly implemented patient-reported outcome instruments are available for both AF and HF and can easily measure hrQoL in each disease process. A better understanding of the diverse phenotypes of AF and HF, as well as the heterogeneous treatment effects of disease-specific interventions, is necessary to further disentangle the complex relationship between symptoms of AF and HF.

Abstract P126: The Cardiovascular Health of Afro-Caribbean Immigrants in New York City: a Cross Sectional Study

Introduction: Afro-Caribbean (AC) immigrants are the largest black immigrant group in the U.S. and generally display better physical health than United States (U.S.) born blacks. Cardiovascular health (CVH) disparities among AC immigrant sub-groups are poorly understood. We examined the prevalence of CVH factors among AC immigrants (Guyanese, Haitian and Jamaican) relative to U.S. born blacks residing in New York City. We hypothesized that some AC immigrant sub-groups will have higher rates of CVH factors than U.S. born blacks. Methods: We performed a cross-sectional analysis of pooled data from the 2010-2014 New York City Community Health Survey administrations to estimate the prevalence of CVH and differences among AC immigrant sub-groups. We included 7678 non-Hispanic black participants from Haiti (n=291), Jamaica (n=1031), Guyana (n=369) and U.S. born blacks (5987). Logistic regression was used to examine the association between country of birth and CVH factors. The CVH factors were determined from the AHA’s CVH metrics. We adjusted the models for significant covariates using backward sequential selection. Results: In final adjusted models, in comparison to U.S. born blacks, Jamaican immigrants were more likely to self-report diabetes but were less likely to be overweight/obese. Guyanese immigrants were also less likely to be overweight/obese than U.S. born blacks. There were no significant differences between Haitian immigrants and U.S. born blacks for CVH factors. Conclusions: Although AC immigrants depict superior health status compared to U.S. born blacks, ethnic differences exist in CVH among AC immigrant sub-groups. Efforts to address cardiovascular health factors among black populations in the U.S. should consider ethnic differences that may provide information about the most at-risk populations for disease-specific programmatic or policy interventions.

The effects and contribution of childhood diseases on the geographical distribution of all-cause under-five mortality in Uganda

IntroductionInformation on the causes of death among under-five children is key in designing and implementation of appropriate interventions. In Uganda, civil death registration is incomplete which limits the estimation of disease-related mortality burden especially at a local scale. In the absence of routine cause-specific data, we used household surveys to quantify the effects and contribution of main childhood diseases such as malaria, severe or moderate anaemia, severe or moderate malnutrition, diarrhoea and acute respiratory infections (ARIs) on all-cause under-five mortality (U5M) at national and sub-national levels. We related all-cause U5M with risks of childhood diseases after adjusting for geographical disparities in coverages of health interventions, socio-economic, environmental factors and disease co-endemicities. MethodsData on U5M, disease prevalence, socio-economic and intervention coverage indicators were obtained from the 2011 Demographic and Health Survey, while data on malaria prevalence were extracted from the 2009 Malaria Indicator Survey. Bayesian geostatistical Weibull proportional hazards models with spatially varying disease effects at sub-national scales were fitted to quantify the associations between childhood diseases and the U5M. Spatial correlation between clusters was incorporated via locational random effects while region-specific random effects with conditional autoregressive prior distributions modeled the geographical variation in the effects of childhood diseases. The models addressed geographical misalignment in the locations of the two surveys. The contribution of childhood diseases to under-five mortality was estimated using population attributable fractions. ResultsThe overall U5M rate was 90 deaths per 1000 live births. Large regional variations in U5M rates were observed, lowest in Kampala at 56 and highest in the North-East at 152 per 1000 live births. National malaria parasitemia prevalence was 42%, with Kampala experiencing the lowest of 5% and the Mid-North the highest of 62%. About 27% of Ugandan children aged 6–59 months were severely or moderately anaemic; lowest in South-West (8%) and highest in East-Central (46%). Overall, 17% of children were either severely or moderately malnourished. The percentage of moderately/severely malnourished children varied by region with Kampala having the lowest (8%) and North-East the highest (45%). Nearly a quarter of the children under-five years were reported to have diarrhoea at national level, and this proportion was highest in East-Central (32%) and Mid-Eastern (33%) and lowest in South-West (14%). Overall, ARIs in the two weeks before the survey was 15%; highest in Mid-North (22%) and lowest in Central 1 (9%). At national level, the U5M was associated with prevalence of malaria (hazard ratio (HR) = 1.74; 95% BCI: 1.42, 2.16), severe or moderate anaemia (HR =1.37; 95% BCI: 1.20, 1.75), severe or moderate malnutrition (HR = 1.49; 95% BCI: 1.25, 1.66) and diarrhoea (HR = 1.61; 95% BCI: 1.31, 2.05). The relationship between malaria and U5M was important in the regions of Central 2, East-Central, Mid-North, North-East and West-Nile. Diarrhoea was associated with under-five deaths in Central 2, East-central, Mid-Eastern and Mid-Western. Moderate/severe malnutrition was associated with U5M in East-Central, Mid-Eastern and North-East. Moderate/severe anaemia was associated with deaths in Central 1, Kampala, Mid-North, Mid-Western, North-East, South-West and West-Nile.At the national level, 97% (PAF = 96.9; 95%BCI: 94.4, 98.0), 91% (PAF = 90.9; 95%BCI: 84.4, 95.3), 89% (PAF = 89.3; 95%BCI: 76.0,93.8) and 93% (PAF = 93.3 95%BCI: 87.7,96.0) of the deaths among children less than five years in Uganda were attributable to malaria, severe/moderate anaemia, severe/moderate malnutrition and diarrhoea respectively. The attribution of malaria was comparable in Central 2, East-Central, Mid-North, North-East and West-Nile while severe/moderate anaemia was more common in all regions except Central 2, East-Central and Mid-Eastern. The attribution of diarrhoea in Central 2, East-Central, Mid-Eastern and Mid-Western was similar. The attribution of severe/moderate malnutrition was common in East-Central, Mid-Eastern and North-East. ConclusionIn Uganda, the contribution and effects of childhood diseases on U5M vary by region. Majority of the under-five deaths are due to malaria, followed by diarrhoea, severe/moderate anaemia and severe/moderate malnutrition. Thus, strengthening disease-specific interventions especially in the affected regions may be an important strategy to accelerate progress towards the reduction of the U5M as per the SDG target by 2030. In particular, Indoor Residual Spraying, iron supplementation, deworming, exclusive breastfeeding, investment in nutrition and education in nutrition practices, oral rehydration therapy or recommended home fluid, improved sanitation facilities should be improved.

European aid and health system strengthening: an analysis of donor approaches in the DRC, Ethiopia, Uganda, Mozambique and the global fund

ABSTRACTBackground: In the field of international health assistance (IHA), there is a growing consensus on the limits of disease-specific interventions and the need for more health system strengthening (HSS). European donors are considered to be strong supporters of HSS. Nevertheless, little is known about how their support for HSS translates into concrete policies at partner country level. Furthermore, as development cooperation is a shared policy between the EU and its Member States, it remains unclear to what extent European donors share a similar approach.Objective: This article reviews a PhD thesis on European aid and HSS. The thesis investigated (1) the approaches of European donors towards IHA, and (2) the extent to which there are similarities or differences between them. An original analytical framework was developed to make a fine-grained analysis of European donors’ approaches in the DRC, Ethiopia, Uganda and Mozambique. In addition, the relation of European donors with the Global Fund was investigated.Methods: An abductive research approach was used during which literature review, data generation, analysis and research design mutually influenced each other. The research built on a wide range of empirical data, including semi-structured interviews with 123 respondents, policy documents and descriptive statistical analysis.Results and conclusion: Four ‘types’ of European donors were identified, which vary in their focus (issue-specific versus comprehensive) and their level of support to and involvement of recipient states. Despite this heterogeneity at a specific level, there is still a general degree of ‘unity’ among European donors, especially compared with the US. Yet, there are signs that the ‘transatlantic’ divide on HSS may be converging, as European donors tend to focus more explicitly on result-oriented approaches traditionally associated with the US and Global Health Initiatives. Consequently, European donors play a limited role in bringing HSS more to the forefront in IHA.

Storage lipid studies in tuberculosis reveal that foam cell biogenesis is disease-specific.

Foam cells are lipid-laden macrophages that contribute to the inflammation and tissue damage associated with many chronic inflammatory disorders. Although foam cell biogenesis has been extensively studied in atherosclerosis, how these cells form during a chronic infectious disease such as tuberculosis is unknown. Here we report that, unlike the cholesterol-laden cells of atherosclerosis, foam cells in tuberculous lung lesions accumulate triglycerides. Consequently, the biogenesis of foam cells varies with the underlying disease. In vitro mechanistic studies showed that triglyceride accumulation in human macrophages infected with Mycobacterium tuberculosis is mediated by TNF receptor signaling through downstream activation of the caspase cascade and the mammalian target of rapamycin complex 1 (mTORC1). These features are distinct from the known biogenesis of atherogenic foam cells and establish a new paradigm for non-atherogenic foam cell formation. Moreover, they reveal novel targets for disease-specific pharmacological interventions against maladaptive macrophage responses.

Challenges and strategies among women and men with Parkinson’s disease: Striving toward joie de vivre in daily life

Introduction To offer people with Parkinson’s disease optimal occupational therapy, it is important to have a detailed understanding of how they manage everyday life. The aims of this study were to explore how people with Parkinson’s disease manage the effect of the disease on everyday life and to investigate gender similarities and differences concerning this issue. Method We interviewed 24 people with Parkinson’s disease (14 men), at a mean of 8 years after diagnosis. The interviews were analysed according to Grounded Theory. Findings ‘Striving to maintain a good everyday life’ was established as a core category. To overcome obstacles caused by the disease, the interviewees struggled with perpetual adaptation to the medication regime and ongoing changes in their abilities. To achieve best possible everyday life, it was essential to keep their own spirit up; for example, by prioritising valued occupations. Women and men contributed to all categories and used the same strategies. Conclusion Men and women with Parkinson’s disease used the same strategies to manage daily life challenges. Our findings support the relevance of disease-specific occupational therapy interventions focusing on the individual fit between person, environment and occupation, and highlight the need for joyful occupations to attain a satisfactory daily life.

Minority Equity and Recruitment Into Trials program: Self-assessment of disease-specific cancer clinical trial recruitment patterns at a comprehensive cancer center.

267 Background: Prostate cancer disparities research has largely focused on access to care, treatment, and outcomes. Disparities based on race/ethnicity in clinical trial (CT) participation are less well understood. African American men are known to have an increased risk of developing and dying from prostate cancer compared to their white counterparts yet remain underrepresented in prostate cancer CTs. The goal of this study was to examine the demographic accrual patterns in prostate cancer CTs at an academic cancer center. Methods: A retrospective analysis of demographic data of cancer cases per year was performed from: 1) the central cancer registry of California, Surveillance, Epidemiology, and End Results; 2) new patients (“analytic cases”) identified in the University of California, San Francisco (UCSF) cancer registry; and (3) the UCSF Clinical Trials Management System database. The Catchment Area for the center was prospectively defined, and patients from this region comprised 98% of all cancer cases seen at UCSF. Descriptive statistics were applied to characterize CT accruals for men with prostate cancer relative to cases in our Catchment Area. Results: Overall there were 67,046 new cancer cases of all types in the Catchment Area, of which 6,558 were prostate cancer cases. The distribution of patients with prostate cancer by ethnicity/minority status are summarized (Table). Conclusions: The distribution of minority accruals to prostate cancer CTs conducted at academic cancer centers may not reflect overall accruals to all CTs. At UCSF, the accrual of Latino men with prostate cancer to CTs was representative of the Catchment Area, whereas Asian and Black men were under-represented. These results suggest that tailored, disease-specific interventions are required to achieve equitable CT recruitment.[Table: see text]

Burden and Management of Noncommunicable Diseases After Earthquakes and Tsunamis.

This integrative review examines extant literature assessing the burden and management of noncommunicable diseases 6 months or more after earthquakes and tsunamis. We conducted an integrative review to identify and characterize the strength of published studies about noncommunicable disease-specific outcomes and interventions at least 6 months after an earthquake and/or tsunami. We included disasters that occurred from 2004 to 2016. We focused primarily on the World Health Organization noncommunicable disease designations to define chronic disease, but we also included chronic renal disease, risk factors for noncommunicable diseases, and other chronic diseases or symptoms. After removing duplicates, our search yielded 6,188 articles. Twenty-five articles met our inclusion criteria, some discussing multiple noncommunicable diseases. Results demonstrate that existing medical conditions may worsen and subsequently improve, new diseases may develop, and risk factors, such as weight and cholesterol levels, may increase for several years after an earthquake and/or tsunami. We make 3 recommendations for practitioners and researchers: (1) plan for noncommunicable disease management further into the recovery period of disaster; (2) increase research on the burden of noncommunicable diseases, the treatment modalities employed, resulting population-level outcomes in the postdisaster setting, and existing models to improve stakeholder coordination and action regarding noncommunicable diseases after disasters; and (3) coordinate with preexisting provision networks, especially primary care.

Chapter 22 - Motor neurone disease

Motor neurone disease (MND) patients exhibit poor gait, balance, and postural control, all of which significantly increases their risk of falling. Falls are frequent in the MND population, and are associated with an increased burden of disease. The complex interplay of both motor and extramotor manifestations in this disease contributes to the heterogeneous and multifactorial causes of such dysfunction. This review highlights the pathophysiologic influence of motor degeneration in gait disturbance, but also the additional influence on postural instability from other inputs such as cognitive impairment, autonomic dysregulation, cerebellar dysfunction, sensory impairment, and extrapyramidal involvement. In various combinations, these impairments are responsible for reduced gait speed and alteration in gait cycle, as well as structurally more variable and disorganized gait patterns. Based on these features, this chapter will also provide disease-specific interventions to assess, manage, and prevent falls in the MND cohort.

Linking Economic Recessions and Health: Reaffirming the Importance of the Global South in the Debate

In the aftermath of the 2007-2009 global recession and the sovereign debt crises that ensued, a surge in the analysis of the correlation between employment/income and health has continued to puzzle academics and policymakers alike. Although recessions and unemployment are, seemingly paradoxically, positively correlated with mortality and negatively correlated with various health problems (like heart diseases and injuries) in the Global North, the results are far more glum in the Global South where recessions and low employment are associated uniquely with negative externalities on health. This critical review draws on literature from both economics and public health in order to outline the importance of safety nets and the types of programs that best suit the policy needs to insulate individuals from the fallout of unemployment during economic downturns, with a particular focus on impoverished regions. A specific look at the recessionary impacts on development assistance for health (DAH) supports investing more heavily on health system strengthening (HSS), and system-wide (horizontal) approaches rather than disease-specific (vertical) interventions. Other findings suggest investing more heavily in social safety nets rather than health safety nets by tailoring support programs encouraging prevention and supporting the various social determinants of health.

Chronic kidney disease.

Chronic kidney disease (CKD) is defined by persistent urine abnormalities, structural abnormalities or impaired excretory renal function suggestive of a loss of functional nephrons. The majority of patients with CKD are at risk of accelerated cardiovascular disease and death. For those who progress to end-stage renal disease, the limited accessibility to renal replacement therapy is a problem in many parts of the world. Risk factors for the development and progression of CKD include low nephron number at birth, nephron loss due to increasing age and acute or chronic kidney injuries caused by toxic exposures or diseases (for example, obesity and type 2 diabetes mellitus). The management of patients with CKD is focused on early detection or prevention, treatment of the underlying cause (if possible) to curb progression and attention to secondary processes that contribute to ongoing nephron loss. Blood pressure control, inhibition of the renin-angiotensin system and disease-specific interventions are the cornerstones of therapy. CKD complications such as anaemia, metabolic acidosis and secondary hyperparathyroidism affect cardiovascular health and quality of life, and require diagnosis and treatment.
