Oncology practitioners' perspectives and practice patterns of post-treatment cancer survivorship care in the Asia-Pacific region: Results from the STEP study
No full textBackground: Most efforts to advance cancer survivorship care have occurred in Western countries. There has been limited research towards gaining a comprehensive understanding of survivorship care provision in the Asia-Pacific region. This study aimed to establish the perceptions of responsibility, confidence, and frequency of survivorship care practices of oncology practitioners and examine their perspectives on factors that impede quality survivorship care. Methods: A cross-sectional survey of hospital-based oncology practitioners in 10 Asia-Pacific countries was undertaken between May 2015-October 2016. The participating countries included Australia, Hong Kong, China, Japan, South Korea, Thailand, Singapore, India, Myanmar, and The Philippines. The survey was administered using paper-based or online questionnaires via specialist cancer care settings, educational meetings, and professional organisations. Results: In total, 1501 oncology practitioners participated in the study. When comparing the subscales of responsibility perception, frequency and confidence, Australian practitioners had significantly higher ratings than practitioners in Hong Kong, Japan, Thailand, and Singapore (all p < 0.05). Surprisingly, practitioners working in Low- and Mid- Income Countries (LMICs) had higher levels of responsibility perception, confidence and frequencies of delivering survivorship care than those working in High-Income Countries (HICs) (p < 0.001), except for the responsibility perception of care coordination where no difference in scores was observed (p = 0.83). Physicians were more confident in delivering most of the survivorship care interventions compared to nurses and allied-health professionals. Perceived barriers to survivorship care were similar across the HICs and LMICs, with the most highly rated items for all practitioners being lack of time, dedicated educational resources for patients and family members, and evidence-based practice guidelines informing survivorship care. Conclusions: Different survivorship practices have been observed between HICs and LMICs, Australia and other countries and between the professional disciplines. Future service planning and research efforts should take these findings into account and overcome barriers identified in this study
Mapping unmet supportive care needs, quality-of-life perceptions and current symptoms in cancer survivors across the Asia-Pacific region: Results from the International STEP Study
No full textService availability and readiness for hip fracture care in low- and middle-income countries in South and Southeast Asia
No full textAims: The aim of this study was to describe the current pathways of care for patients with a fracture of the hip in five low- and middle-income countries (LMIC) in South Asia (Nepal and Sri Lanka) and Southeast Asia (Malaysia, Thailand, and the Philippines). Methods: The World Health Organization Service Availability and Readiness Assessment tool was used to collect data on the care of hip fractures in Malaysia, Thailand, the Philippines, Sri Lanka, and Nepal. Respondents were asked to provide details about the current pathway of care for patients with hip fracture, including pre-hospital transport, time to admission, time to surgery, and time to weightbearing, along with healthcare professionals involved at different stages of care, information on discharge, and patient follow-up. Results: Responses were received from 98 representative hospitals across the five countries. Most hospitals were publicly funded. There was consistency in clinical pathways of care within country, but considerable variation between countries. Patients mostly travel to hospital via ambulance (both publicly- and privately-funded) or private transport, with only half arriving at hospital within 12 hours of their injury. Access to surgery was variable and time to surgery ranged between one day and more than five days. The majority of hospitals mobilized patients on the first or second day after surgery, but there was notable variation in postoperative weightbearing protocols. Senior medical input was variable and specialist orthogeriatric expertise was unavailable in most hospitals. Conclusion: This study provides the first step in mapping care pathways for patients with hip fracture in LMIC in South Asia. The previous lack of data in these countries hampers efforts to identify quality standards (key performance indicators) that are relevant to each different healthcare system.

Quality Indicators and Clinical Outcomes of Acute Stroke: Results from a Prospective Multicenter Registry in Greece (SUN4P)
No full textAim: The Stroke Units Necessity for Patients (SUN4P) project aims to provide essential data on stroke healthcare in Greece. Herein, we present results on established quality indicators and outcomes after first-ever stroke occurrences. Methods: This prospective multicenter study included consecutive patients admitted to nine hospitals across Greece in 2019–2021. Descriptive statistics were used to present patients’ characteristics, key performance measures and stroke outcomes. Results: Among 892 patients, 755 had ischemic stroke (IS) (mean age 75.6 ± 13.6, 48.7% males) and 137 had hemorrhagic stroke (HS) (mean age 75.8 ± 13.2, 57.7% males). Of those, 15.4% of IS and 8% of HS patients were treated in the acute stroke unit (ASU) and 20.7% and 33.8% were admitted to the intensive care unit (ICU) or high-dependency unit (HDU), respectively. A total of 35 (4.6%) out of 125 eligible patients received intravenous alteplase with a door-to needle time of 60 min (21–90). The time to first scan for IS patients was 60 min (31–105) with 53.2% undergoing a CT scan within 60 min post presentation. Furthermore, 94.4% were discharged on antiplatelets, 69.8% on lipid-lowering therapy and 61.6% on antihypertensives. Oral anticoagulants (OAC) were initiated in 73.2% of the 153 IS patients with atrial fibrillation (AF). Among the 687 IS patients who survived, 85.4% were discharged home, 12% were transferred to rehabilitation centers, 1.2% to nursing homes and 1.3% to another hospital. Conclusions: The SUN4P Registry is the first study to provide data from a prospectively collected cohort of consecutive patients from nine representative national hospitals. It represents an important step in the evaluation and improvement of the quality of acute stroke care in Greece
Cyclic variation of the common carotid artery structure in relation to prior atherosclerotic burden and physical activity
No full textBackground and aims: Cardiovascular disease (CVD) accounts for the most deaths of non-communicable diseases worldwide. It begins with structural and functional changes of the arterial system commonly known as the atherosclerotic process, starting asymptomatically in early childhood, adapting arterial structure and function with advancing age depending on genetic and environmental exposures and finally resulting in CVD events such as myocardial infarction or stroke. CVD
risk prediction today is generally based on risk scores, but substantial disadvantages occur since they account only for specific risk factors at one time point. Carotid structure and function (also called carotid stiffness) parameters measured by ultrasound may overcome this disadvantage, since they can provide information on structural and elastic carotid properties and reflect therefore vascular damage accumulated over time.
Thus, the aims of this thesis were to summarize the state of the art of ultrasound measurements, to validate the new developed ultrasound analysis system, to assess the variability and reproducibility within the study sample and to investigate the long- and short-term associations of cardiovascular risk factors and carotid stiffness with main focus on physical activity in elderly participants of the SAPALDIA cohort.
Methods: The SAPALDIA cohort study is an ongoing multicenter study with a population-based random sample of adults from eight rural and urban areas started in 1991 (SAPALDIA 1), with a first follow-up in 2001-2003 (SAPALDIA 2) and a second follow-up in 2010-2011 (SAPALDIA 3). In SAPALDIA 3, sequential B-mode ultrasound images of the common carotid artery were examined in 3489 participants (51% women) aged between 50-81 years at the time of examination. Expert readers analyzed these ultrasound images with a new analysis system called DYARA (DYnamic ARtery Analysis) according to the state of the art assessed in the review. Thereof, carotid structure parameters were measured and carotid stiffness indices were derived considering blood pressure at time of ultrasound assessment. Validation of the ultrasound analysis program DYARA and reproducibility of carotid parameters were performed in subgroup within the SAPALDIA 3 survey. The presented studies within this thesis comprise cardiovascular risk factor data from the first and second follow-up and therefore, long- and short-term associations with carotid stiffness could be investigated.
Results: The intra- and inter-reader results of the validation study were highly consistent with slightly higher bias for analyses with manual interactions compared to the automatic detection. Among the carotid structure parameters, average values across heart cycle showed lower variability than single images in diastole and systole, whereby the relative difference was smaller in lumen diameter values compared to the carotid intima media thickness (CIMT). Based on different statistical approaches, reproducibility values within SAPALDIA 3 were consistently good to excellent for carotid structure and function indices. Findings additionally revealed that subjects itself were the greatest source of variability between two measurements.
Multivariate regression analyses suggested that most single cardiovascular risk factors in SAPALDIA 2 were long-termly associated with increased carotid stiffness in SAPALDIA 3 except physical activity and high-density lipoprotein cholesterol (HDL-C). HDL-C was the only protective vascular determinant and no relation was observed for physical activity. Most carotid stiffness parameters were similar strong associated within each cardiovascular risk factor (except compliance showed main deviances among several risk factors). Estimating sex-specific associations of atherosclerotic risk factors and carotid stiffness indicated that increased heart rate was more strongly associated with stiffer arteries across all carotid stiffness parameters in men than in women. Low-density lipoprotein cholesterol (LDL-C) was significantly associated with carotid stiffness only in men and triglyceride only in women.
Multifactorial pathway analyses of cardiovascular risk factors in SAPALDIA 3 showed that age was the strongest predictor of carotid stiffness, followed by mean arterial blood pressure and heart rate. Age strongly confounded the association of physical activity and carotid stiffness in multiple regression analyses and therefore, only an univariate association of physical activity and carotid stiffness could be observed.
Conclusion: DYARA tackles the challenge of being able to analyze varying ultrasound image qualities with high precision. The high reproducibility and the feasible application in a large sample size suggest that this program can be recommended for epidemiological research, diagnostics and clinical practice. Long- and short-term cardiovascular exposures have added important information to the overall vascular damage assessed by carotid stiffness for both sexes. Although age was the strongest predictor, sex-differences in long-term associations may indicate a certain differentiated susceptibility to cardiovascular risk factors among men and women, which should be investigated in more detail.
The presented studies within this thesis provide an important basis towards future investigations targeting the early and late consequences of atherosclerosis, its progression and possible implementations of preventive and/or personalized interventions
Involving young people in BRIGHTLIGHT from study inception to secondary data analysis: insights from 10 years of user involvement
No full textPlain English summary Young people with cancer are often described as ‘hard to reach’, ‘difficult to engage’ and/or ‘vulnerable’. Consequently, they are often over looked for patient and public involvement activities. We set out to involve young people with cancer to work as co-researchers in the design of the largest ever study of young people with cancer, called BRIGHTLIGHT. In the 10 years since the BRIGHTLIGHT feasibility work began we have involved more than 1200 young people as co-researchers, collaborators, consultants and dissemination partners. We chronicle the key points of this 10-year journey, sharing our success, describing our challenges and the solutions we put in place; sharing also what worked and did not work. Here we share some of these experiences of involving young people in this research and offer some practical advice for those looking to do the same. Abstract Background Young people with cancer, broadly those aged 13–24 years at diagnosis, warrant special attention; physiological and psychological growth creates complex psychosocial needs which neither adult nor child systems are suitably designed to deal with. Resulting from these needs, they are often described as ‘vulnerable’, ‘hard to reach’ and ‘difficult to engage’, and consequently are often over looked for patient and public involvement/engagement (PPIE) roles. In our study ‘BRIGHTLIGHT’, we set out to evaluate whether specialist care for young people adds value, ensuring young people were central to our PPIE activities. We believe that BRIGHTLIGHT is unique as a very large study of young people with cancer which has successfully overcome the challenges of including young people in the research process so we are confident that they have influenced every aspect of study design, conduct and dissemination. Methods We chronicle a period of 10 years, over which we describe our approach and our methods to involving young people in PPIE activities in BRIGHTLIGHT. We describe the feasibility work, study set up, conduct and dissemination of our findings, and weave through our story of PPIE to illustrate its benefits. Through the narration of our experience we highlight significant points that both influenced and changed our direction of travel. We reflect on our experiences and offer some practical advice for those looking to do the same. Results In the 10 years since the BRIGHTLIGHT feasibility work began we have involved more than 1200 young people. Their contributions have been isolated and mapped over a 10-year period. We begin at an early step of identifying what research questions to prioritize, we then plot PPIE activities for one of these research priorities, place of care, which evolved into BRIGHTLIGHT. We document steps along the way to evidence the impact of this involvement. Conclusions Young people can make a valuable contribution to healthcare research given adequate support from the research team. Although some challenges exist, we propose that the benefits to young people, researchers and the study considerably outweigh these challenges and PPIE with young people should be integrated in all similar research studies
The impact of the newer knowledge of nutrition: nutrition science and nutrition policy, 1900-1939.
No full textIdeas concerning relationships between diet and health in the UK are
traced from the 1904 Comittee on Physical Deterioration to the outbreak
of World War II. Archive material is used to describe the often
conflicting views of the Medical Research Council and the Ministry of
Health and Board of Education concerning the public health applications
of nutrition science. In particular, the work of the Ministry of
Health's first Advisory Comittee on Nutrition, which was appointed in
1931, is reviewed and evaluated. The debate among public healh
practitioners over the nature, cause and extent of the 'nutrition
problem' is documented and the role in this debate of official dietary
guidelines which appeared during the 1930s, is assessed.
The Impact of the Newer Knowledge of Nutrition on welfare feeding policy
Is evaluated in the context of the official promotion of milk feeding in
schools. In particular, Corry Mann's experimental evidence which was
used to endorse this policy, is reconsidered, and it is shown that the
NRC view that the trial was proof of the presence in milk of a "growth
factor" which produced preferential growth efficiency in adequately fed
children , was in error. From a re-evaluation of the evidence it is
suggested that the experiment merely recorded catch-up growth in a group
of poorly nourished children. The view that there existed an extensive
nutritional problem due to poor quality diets is examined and
challenged.
Both dietary survey data and anthropometric evidence are used to present
the case that there was throughout the period studied a widespread
problem of underfeeding among the poor and that intervention strategies
based on the Newer Knowledge were not an appropriate method of dealing
with this problem. This casts doubts on the widely held view that there
was a need for nutrition education and suggests that the problem was one of poverty rather than Ignorance. Disaggregated anthropometric data
located by the author are analysed according to NCHS standards to assess
the prevalence of underfeeding. Significantly higher prevalences of
stunting than low weight-for-age exist in all data sets; this phenomenon
is considered in detail and low weight-for-age is proposed as the
preferred index of malnutrition in 20th Century historical studies.
Attention is drawn to the relevance of these studies for the current
nutrition and public health debate
Estimates of global, regional, and national incidence, prevalence, and mortality of HIV, 1980-2015 : the Global Burden of Disease Study 2015.
No full textBACKGROUND: Timely assessment of the burden of HIV/AIDS is essential for policy setting and programme evaluation. In this report from the Global Burden of Disease Study 2015 (GBD 2015), we provide national estimates of levels and trends of HIV/AIDS incidence, prevalence, coverage of antiretroviral therapy (ART), and mortality for 195 countries and territories from 1980 to 2015. METHODS: For countries without high-quality vital registration data, we estimated prevalence and incidence with data from antenatal care clinics and population-based seroprevalence surveys, and with assumptions by age and sex on initial CD4 distribution at infection, CD4 progression rates (probability of progression from higher to lower CD4 cell-count category), on and off antiretroviral therapy (ART) mortality, and mortality from all other causes. Our estimation strategy links the GBD 2015 assessment of all-cause mortality and estimation of incidence and prevalence so that for each draw from the uncertainty distribution all assumptions used in each step are internally consistent. We estimated incidence, prevalence, and death with GBD versions of the Estimation and Projection Package (EPP) and Spectrum software originally developed by the Joint United Nations Programme on HIV/AIDS (UNAIDS). We used an open-source version of EPP and recoded Spectrum for speed, and used updated assumptions from systematic reviews of the literature and GBD demographic data. For countries with high-quality vital registration data, we developed the cohort incidence bias adjustment model to estimate HIV incidence and prevalence largely from the number of deaths caused by HIV recorded in cause-of-death statistics. We corrected these statistics for garbage coding and HIV misclassification. FINDINGS: Global HIV incidence reached its peak in 1997, at 3·3 million new infections (95% uncertainty interval [UI] 3·1-3·4 million). Annual incidence has stayed relatively constant at about 2·6 million per year (range 2·5-2·8 million) since 2005, after a period of fast decline between 1997 and 2005. The number of people living with HIV/AIDS has been steadily increasing and reached 38·8 million (95% UI 37·6-40·4 million) in 2015. At the same time, HIV/AIDS mortality has been declining at a steady pace, from a peak of 1·8 million deaths (95% UI 1·7-1·9 million) in 2005, to 1·2 million deaths (1·1-1·3 million) in 2015. We recorded substantial heterogeneity in the levels and trends of HIV/AIDS across countries. Although many countries have experienced decreases in HIV/AIDS mortality and in annual new infections, other countries have had slowdowns or increases in rates of change in annual new infections. INTERPRETATION: Scale-up of ART and prevention of mother-to-child transmission has been one of the great successes of global health in the past two decades. However, in the past decade, progress in reducing new infections has been slow, development assistance for health devoted to HIV has stagnated, and resources for health in low-income countries have grown slowly. Achievement of the new ambitious goals for HIV enshrined in Sustainable Development Goal 3 and the 90-90-90 UNAIDS targets will be challenging, and will need continued efforts from governments and international agencies in the next 15 years to end AIDS by 2030.Funding: We thank the countless individuals who have contributed to the Global Burden of Disease (GBD) Study 2015 in various capacities.

Evidence and guidance on vaccine safety and effectiveness in subpopulations
No full textThis dissertation examines post-licensing vaccine safety and effectiveness against two major respiratory diseases in specific subpopulations, with emphasis on safety. First, inactivated influenza vaccination in pregnant women is reviewed, and a comparison is made of national influenza vaccine policies. Second, a systematic review is conducted and the pooled risk estimate calculated on the risk of disseminated disease from bacille Calmette-GuŽrin (BCG) vaccination in infants infected with human immunodeficiency virus (HIV). Potential impacts on immunisation programmes are considered for settings with different burdens of disease and levels of resources. Third, a review of the evidence-based management of BCG-related adverse events is performed, towards developing useful guidelines for healthcare providers. There may be little pre-licensing data on a chemical drug or vaccineÕs profile in subpopulations, although certain groups may be more vulnerable to the disease. As described, post-licensing studies that evaluate subpopulations provide vital information because these groups are often excluded in clinical trials as well as neglected in drug development. The immunological mechanisms of vaccine safety and effectiveness play a key underlying role in the differential risk of adverse events from the natural disease or from the vaccination in certain subpopulations. Influenza and tuberculosis are respiratory infections having enormous global health impacts. Pregnant women and HIV-infected subpopulations are groups known to be vulnerable to certain infectious diseases. Continual, careful appraisal of the evidence for vaccine safety informs policy and upholds the public trust placed in immunisation programmes
