The number of refugees arriving in Europe continues to rise, despite the EU-Turkey deal struck in March 2016 aimed at halting the numbers of new arrivals. This deal represented one of the first consensual decisions made by the 28 member states of how to respond to the unprecedented refugee crisis in Europe seen over recent years. However, across Europe there remains an overwhelming lack of political effectiveness, or indeed will, to co-ordinate the care of those arriving on the continent. Supranational institutions, European governance bodies, NGOs and humanitarian partners have scrambled in varying degrees of commitment to offer their services to refugees and the impression for many is that they are not achieving enough, quickly enough. But how have the various actors responded to the health needs of the refugees, and who is held accountable for this most basic human necessity?

Arrival versus Settlement

There is a significant difference between the immediate and long-term healthcare needs seen among refugee populations. This protracted crisis must be able to respond to both the immediate and often-life saving measures needed on Greek islands where refugees are still arriving by boat, and the long-term needs of refugees who have settled in host countries, in many cases for months or even years. Understanding this transition between the emergency and post-emergency phase, is essential for planning an effective healthcare response. The needs of those new arrivals mostly consists of sanitation, nutrition, shelter and basic safety provision, whilst those further along the asylum process must be integrated into long-term health systems that provide them with more complex and comprehensive services such as chronic disease management.

 As it stands, the initial needs of refugees arriving to European shores are often provided by humanitarian agencies who are equipped to launch an emergency response, and gradually they hand over this responsibility to the local health care structures. An excellent example of this was seen in Bulgaria when Doctors without Borders provided medical care to over 1500 refugees, allowing the national authorities who have now taken over healthcare service provision in this area, to build capacity and prepare (1). In many places this handover scenario has not been achieved so clearly and in fact often it is best for organisations and local partners to share the healthcare responsibilities. For example in Piraeus port in Athens (now dissolved), NGOs such as Praxis and the Red Cross were stationed within the camp itself and acted as primary care providers to the population on the ground, referring patients who required more specialised care on to state-run and funded hospitals or clinics in Athens. A similar system is currently established between the residents of the Jungle camp in Calais and the PASS clinic (Permanence d'Accès aux Soins de Santé)-provided by the government for refugees and others without social security insurance in France. However the extent to which this collaborative effort is effective depends much on the nature of the healthcare needs required; patients with mental health issues requiring long-term psychological treatment or those with post-surgery rehabilitation needs are often prematurely discharged or simply not offered longstanding care. Logistical difficulties are also often neglected as many appointments and consultations are arranged in neighbouring cities and patients are required to arrange their own transport which for many is an impossibility.  Achieving adequate provision and access in healthcare for refugees is complex and is largely dependent on context, their status in the asylum process and capacities of local health organisations.

The ‘Unofficial’ Refugee

Much complexity has been added to this crisis by the lack of clarity in defining those who are arriving in Europe- undocumented migrants, labour migrants, refugees and asylum seekers are terms often confused and used interchangeably and this has an impact on how these people can interact with official services. As refugees and others spread across Europe, the way in which they settle varies dramatically-there are families living in air-conditioned containers in official UN-led refugee camps, whilst others squat in abandoned buildings in the suburbs of Athens. This undoubtedly leads to much heterogeneity in terms of both their access to and quality of healthcare. Much of the healthcare that refugees living in official camps receive is provided by large, international NGOs such as Doctors without Borders (MSF) or the Red Cross. These organisations provide high-standard medical and nursing care, including psychological support in many cases, and also organise public health services such as child immunisations. As priority for official camp accommodation is usually given to families with children or vulnerable people with either chronic diseases or disabilities, providing comprehensive healthcare services to these populations is even more imperative. What this means however, is that resources are stretched thin and those refugees who are either in transit or living in unofficial areas often receive a lower quality or even a complete lack of healthcare.

The legal status of a refugee can also be a barrier to seeking healthcare, particularly in the few chaotic months after arrival in Europe. Many do not fully understand their legal rights or how to access healthcare in host countries; this is particularly problematic for those who are not settled immediately into official camps, instead attempting to cross international borders or avoid registration for fear of the barriers this may pose to freedom of movement (2). This means many do not receive their healthcare entitlements and depend on the ad-hoc and inconsistent presence of healthcare-providing groups often from outside any official aid delivery process.

The ‘unofficial’ refugee population is in fact where the grassroots organisations have trumped more established humanitarian groups. Countless groups have been set up in recent years by concerned citizens across Europe and have provided the in-the-field manpower that many official partners have failed to do. Groups such as Drop in the Ocean, Care 4 Calais, Help Refugees and many others have integrated into the ‘official’ aid delivery system and have in many cases outpaced those organisations who are often restricted by mandates or internal bureaucracy.  These groups offer assistance that is not always recorded on health surveillance statistics or official reports but in fact they are in many cases acting as primary carers. As healthcare itself is not the only way of keeping refugees healthy, these groups who attend to other needs such as shelter and food provision, hygiene, childcare and education may actually be having a significant impact on the refugee population’s health (3).

What about the Supranationals?

Under the 1951 Refugee Convention, refugees should enjoy access to health services equivalent to the host population, and institutions such as the World Health Organisation (WHO) and the Office of the United Nations High Commissioner for Refugees (UNHCR) are tasked with upholding these rights under the UN Charter (4). It is increasingly clear that Europe is struggling to deal with the crisis and the UN has put pressure on European governance bodies to establish a comprehensive, mutually-agreed response plan to address the health needs of the refugee populations. This has achieved some success particularly in communicable disease control with large-scale vaccination programmes used in camps and non-camp settings alike (5) (see photo).

 However, the long-term nature of this crisis will require more of a focus on capacity-building of existing healthcare structures in host countries. For this reason, the WHO has performed a number of Assessment missions in countries receiving the most footfall of refugee movement including Cyprus, Greece, Italy and others, providing countries with context-specific information and guidance on responding to the health needs of refugees either temporarily or permanently settling in these countries (6). These analyses of the current preparedness of national health structures have helped to pinpoint where increased funding or skills are needed to boost local response; the European Commission have subsequently invested over 5 million euros on projects with the aim of “supporting member states under particular migratory pressure in their response to health-related challenges” (7). Crucially, these projects integrate NGOs with national structures, bridging the gap between short and long-term response, and focus on fostering comprehensive access to all aspects of the health system, not only emergency care. One of these projects also places a particular focus on the health needs of pregnant women, unaccompanied minors and young children, highlighting a concern for the most vulnerable populations in this crisis (7). However, whilst these projects are theoretical problem-solvers, there is a gap between plan and action. Many projects will take years to see results and whilst they do, countries such as Greece are reliant on existing health care systems, which have been struggling for years to cope with both the steady influx of refugees over many years and domestic austerity policies (8).

The bottom line is that funded and elected institutions such as the UN are mandated to protect the rights of refugees and these include access to healthcare. This situation sees the heavily bureaucratised system overloaded and rendered flimsy by the sheer volume of refugees depending on it, not only in Europe. This has meant that other humanitarian partners and grassroots movements have stepped in and provided invaluable assistance on the ground. The provision of healthcare to refugees in Europe largely depends on capacity and it is clear that there must be far-reaching plans made to build on both national and international health system structures. Whether these plans will materialise into effective action that both prevents ill health and treats disease remains to be seen as the crisis, without long-term solutions, inevitably continues.

Battling Cancer across Different Income Settings

~Written by Sarah Khalid Khan (Contact: sk_scarab@yahoo.com)

David Bowie, Alan Rickman and Rene Angelil, are a few of the well-known people that the world lost to cancer in the year 2015. My familiarity with cancer comes not just from losing my favourite celebrities to cancer, or dealing with patients in a tertiary care hospital in Lahore, but also from losing a few people very dear to me in my family. Every case of cancer is a battle for the person, their families, friends and doctors, as well as the healthcare system.

Cancer forms a major proportion of non-communicable diseases today. There were an estimated 14.1 million new diagnosed cases of cancer with an estimated 8.2 million deaths in 2012 (1). The most common sites of cancer have been recognized to be lung, colon, breast, liver, stomach and the cervix while the majority of cancer-related deaths are due to lung, stomach and esophageal cancer (2). Previously, cancer remained a low priority for low income (LICs) and low middle income countries (LMICs), as well as for donors (3). In 2008 72% of deaths due to cancer occurred in LICs and LMICs (4).  This may be a consequence of not only longer life spans and the majority of the world’s population being in the LIC and LMIC countries but also a lack of accessible and affordable treatment in these parts of the world.

While higher income countries have progressed from chemotherapy and radiotherapy to gene therapy, LMICs continue to focus on finding ways for uneducated or less educated to identify cancerous conditions in order to seek medical help before it is too late, for instance promoting breast self-examination. The increasing prevalence of cancer in LMICs exasperates the health sector with an already increasing burden of infectious diseases like tuberculosis, malaria and diarrhea. In these contexts cancer contributes to altering the epidemiology of these countries adding to the burden of non-communicable diseases which in turn worsens the double burden of disease. This creates considerable strain on the healthcare system due to increasing needs of diagnostic and treatment modalities besides the already unmet needs concerning infectious diseases.

There is an immense need for healthcare systems in resource poor settings to focus more on prevention rather than cure. Health professionals working in LMICs need to place greater emphasis on informing and educating people about warning signs of cancer as many resource poor settings have technology constraints and limited means of gaining health information. There are no quick fixes and circumstances are never as simple as they seem. Campaigns against smoking to prevent lung cancer have been addressed by discussions advocating for the rights of the poor who own tobacco farms as their only source of income (5). Modification of social behaviours for instance, requires extensive out-reach programmes by medical professionals but also bring into question the financial constraints of the country in order to pay for the services of these local healthcare workers.

In summary, LICs and LMICs have a longer way to go to provide sufficient healthcare for cancer patients. While high income countries are more likely to make medical advances for cancer treatment, resource poor countries can make strides through preventive measures like vaccination, behaviour modification and self-examination.

Recent Therapeutic Advancements in Combating Dengue and Glioma

Infectious and chronic diseases are some of the top priorities in global health. Abundant funding, both from the government and private sector, is poured into therapeutics research to help decrease morbidity and mortality from both types of diseases. For example, recent news has highlighted two promising therapies with the potential to alleviate the global burden of two diseases: dengue fever, an infectious disease, and glioblastoma, a chronic disease.

After 20 years of research, Sanofi, a French pharmaceutical company, developed Dengvaxia, a vaccine to prevent dengue. Mexico is the first country to approve the vaccine for use in children over the age of nine and adults under the age of 45. A clinical trial last year found the vaccine to have an effectiveness of 60.8% against four strains of the virus[1]. Sanofi bypassed European and US regulations and sought regulatory approval for Dengvaxia in dengue-endemic countries. According to their press release, the vaccine, “will be priced at a fair, affordable, equitable, and sustainable price... and may be distributed for free in certain countries”[2].

Dengue is a febrile viral illness that is spread via the bite of an infected mosquito, and is endemic to tropical and sub-tropical climates. According to the World Health Organization (WHO), about 400 million people globally are infected with the dengue virus each year. Prevention has been limited to effective mosquito control and appropriate medical care[3]. These measures are often either ineffectively implemented, or there are limited, or no available medical resources in the community. Dengvaxia has the potential to reduce the burden of dengue, especially in developing countries that are particularly hard-hit with the disease. Future research could be directed towards making the vaccine more effective in children, as severe forms of dengue are the leading cause of illness and death in children in Asian and Latin American countries[3].

As one tropical virus is being prevented, another virus is being used to combat brain cancer. Researchers at Harvard and Yale have teamed up to use vesicular stomatitis virus (VSV) and Lassa virus, to search for and destroy cancer cells in mice[4]. Lassa is a febrile illness, usually transmitted by rodents, and is endemic to tropical and subtropical regions of the world[5]. VSV has been studied for many years and is generally effective in killing cancer cells; it becomes deadly to the patient when it reaches the brain[4,6]. Interestingly, including Lassa virus appears to make VSV safe for cancer therapy in the brain.

Researchers created a Lassa-VSV chimera, an organism that includes the genetic codes of two different organisms, to target glioma, one of the deadliest forms of brain cancer, which accounts for more than 80% of primary malignant brain tumors[7]. Glioblastoma is the most common form of glioma and is associated with poor survival, making this chimeric treatment a potential life saver for many patients. The next step in the treatment development process is primate research to evaluate safety. This is still a long way from the initiation of human trials, and eventual market, but promising nevertheless, for the millions of people globally who are affected by brain cancer.

Dengvaxia and the Lassa-VSV chimera represent recent advancements in therapeutics with potentially significant global impact for brain cancer and dengue respectively - diseases that affect populations in many nations.

The Cinderella of Health Issues in Pakistan

~Written by Sarah Khalid Khan (Contact: sk_scarab@yahoo.com)

Lahore Mental Hospital

As a Global Health student with a background in medicine I find all health issues interesting. Especially interesting are the mental health issues because of their lack of somatic manifestation like other physical ailments. It is surprising to know that depression alone affects almost 350 million people worldwide (WHO 2015). Even though I have been related to the medical field for quite a while, I underestimated the state of mental health in Pakistan. The fact that I grew up with a family member who was under treatment for bipolar disorder for many years did not do much to change my opinion. I am also related to a few undiagnosed cases of clinical depression but I still did not consider mental health an issue. During my medical college, the clinical rotations in the psychiatric ward also failed to show me the true picture of the burden of mental disease partly due to its scarce patient numbers.

I realise my ignorance even after becoming a clinician reflects poorly on the level of awareness of this issue in the medical community and the general population. I would have continued to be ignorant had it not been for one particular day in the Outdoor Patient Department at Services Hospital Lahore with one of the heads of medicine.

As the last patient left, the professor looked around at all the junior doctors sitting around the table, picked up one of the physician samples and said that if it were up to him, he would make the drinking water of Lahore enriched with it. Surprised at what could possibly plague our part of the world and cure it according to him, we looked at the sample. It was an anxiolytic. An anxiolytic is sometimes prescribed for people suffering from stress and often given to patients with depression (Pietrangelo 2013).

The fact that the number of mental disorders is increasing worldwide is not a secret. According to some sources, the number of people suffering from mental issues in Pakistan is estimated to be around 15 million (Anwar 2015). Most of these remain undiagnosed, often in the shadows of stigma and shame. Pakistan has many reasons to have escalating mental illness; political unrest, internal conflict, economic instability, rising poverty and crime rates, unemployment, natural disasters, the list goes on.

Unfortunately most of these cases are attributed (by the general public, doctors or both) to black magic and evil spirits (Gadit and Callanan 2006). Many such people end up at shrines and the doorsteps of spiritual healers. Some receive holy verses to recite while others get beaten, to scare away the evil spirit or “jinn” as it is called in this part of the world. While religion is good for many reasons, the fact that mental health involves underlying biochemical pathophysiology that could be treated with medical intervention needs to be addressed urgently.

But what about the people who specialize in managing and treating such disorders? According to WHO there are less than 350 psychiatrists in Pakistan, only 0.2 per 100,000 (Jooma et al. 2009). The numbers are worse for pediatric psychiatrists. With only five psychiatric hospitals in the country, the state of psychiatric wards and mental institutions is appalling (Anwar 2015).

Although psychiatry might be an area of increasing interest in medicine in Pakistan, the availability of opportunities that provide better compensation and benefits abroad cause many of these doctors to leave the country to work in “greener” pastures (Imran et al. 2011). With the prevailing conditions for doctors in general, Pakistan might even become an exporter of psychiatrists, which will only worsen the situation within the country.

The time to deal with the multi-headed monster of mental health in Pakistan is now. Raising awareness about mental issues is primary but the need to remove the stigma associated with it is a bigger concern. The truth about fraudulent spiritual healers also needs to be addressed vehemently. The number of psychiatric wards needs to be increased. Finally, the medical workforce needs to be given better incentives to stay within the country.

The Role of the Built Environment in Reducing the Incidence of Type 2 Diabetes

~Written by Joann Varickanickal (Contact: joann.varickanickal@gmail.com)

Diabetes is a chronic disease that affects many people worldwide. Type 1 diabetes is an autoimmune deficiency that often develops in childhood and impacts about 10 percent of those with the disease (Canadian Diabetes Association, 2009). However, type 2 diabetes develops later in life, is influenced by environmental and lifestyle factors, and is prevalent among nearly 90 percent of those with diabetes.  While Type 2 diabetes used to be considered a “disease of the West”, it has now spread to more countries; thus, more efforts need to be made to reduce the incidence of this disease. As healthy diets and regular physical activity are key components to reducing the prevalence of type 2 diabetes, the built environment needs to be taken into consideration. The built environment includes all of the aspects of an environment created by humans, such as neighborhoods and cities, and consequently plays an important role in ensuring that people can access healthy food, and increase physical activity.

The Importance of Community Gardens

The accessibility of healthy foods can increase with the implementation of community gardens. Preliminary studies reveal several benefits of community gardens, including the associated increased intake of produce. One study examined the benefits of community gardens in South-East Toronto, concluding that those who participated in the maintenance of the garden increased their intake of vegetables and fruits and bought fewer produce from grocery stores (Wakefield, Yeudall, Taron, Reynolds, & Skinner, 2007). While these community gardens were established by non-governmental organizations, city planning officials still have a large role to play, as they could ensure that there is land in urban areas specifically designated for community gardens.   

Gardens could also be incorporated into schoolyards. One example of this was in California where the “Garden in Every School” program was implemented, and vegetables and fruits were grown on school property.  The kids helped to maintain the garden and this promoted healthy eating and an overall increase in the local food supply (San Mateo County Food System Alliance, 2010; Dannenberg, Frumkin, & Jackson, 2011).

The Role of Active Transportation

Encouraging physical activity is also a key component in reducing diabetes prevalence and this can be done through changes in the built environment by encouraging active transportaiton. This would involve increasing the walkability of communities through the implementation of pedestrian infrastructure, such as sidewalks and safe crossings, to ensure that these places are easily accessible.  

Encouraging “Smart Growth” would also be important. This concept was developed in the 1990s by initiatives that were being implemented by various organizations, including the American Planning Association (Dannenberg et al., 2011). “Smart Growth” policies encourage the preservation of open space, and making communities more walkable. This could be done through the implementation of mixed-land use development, which would ensure that employment, schools and shops were within close proximity and walking became one of the main methods of transportation.

Another key component of Smart Growth is developing a variety of transportation methods through the implementation of Transit-Oriented Development, which also became prominent in the 1990’s. This would be another way to encourage physical activity and reduce reliance on cars. Implementing bike lanes also encourages biking as a means of transportation. In Portland, Oregon there was an increase in biking after several miles of bike lanes were added, as a quadrupling in bikeway miles resulted in a quadrupling of bicycle bridge traffic (refer to Figure 1).

 

Figure 1: An increase in bikeway miles in Portland, Oregon was led to an increase in bicycle traffic (Dannenberg et al., 2011).

There are other factors to consider when examining type 2 diabetes, such as biological factors among certain ethnic groups, and the difficulties associated with trying to make behavioural changes. However, by making sustainable changes to the built environment to increase accessibility to healthy foods and encourage active transportation, government officials and non-governmental organizations can begin to greatly reduce the prevalence of type 2 diabetes.

Managing the Global Burden of Chronic Illnesses

-Written by Mike Emmerich, Specialist Emergency Med & ERT Africa consultant (contact: mike@nexusmedical.co.za)

https://twitter.com/MikeEmmerich_

An article on an EMS blog caught my eye in the past week:

"COPD was the third-leading cause of death in the U.S. in 2011 and is expected to become the third-leading cause of death worldwide by 2020." (Source: Hoyert DL, Xu JQ. Deaths: preliminary data for 2011. Natl Vital Stat Rep, 2012; 61(6): 1–65. Lopez AD, Shibuya K. Chronic obstructive pulmonary disease: current burden and future projections. Eur Respir J, 2006; 27(2): 397)

This caused me to dig up a presentation I did in 2006 at a Fitness Seminar, wherein I was discussing chronic medical conditions, which are caused by poor lifestyle choices and I noted then:

" In 1999 CVD contributed to a third of global deaths. " In 1999, low and middle income countries contributed to 78% of CVD deaths. " By 2010 CVD is estimated to be the leading cause of death in developing countries. " Heart disease has no geographic, gender or socio-economic boundaries.

I further stated: Chronic illness have overtaken communicable disease as a major cause of death and disability worldwide. Chronic diseases, including such noncommunicable conditions as cardiovascular disease, cancer, diabetes and respiratory disease, are now the major cause of death and disability, not only in developed countries, but also worldwide. The greatest total numbers of chronic disease deaths and illnesses now occur in developing countries.

I then dug deeper to see how this has changed since 2006, and the outlook has become even more bleak!

More than 75% of all deaths worldwide are due to noncommunicable diseases (NCDs). NCD deaths worldwide now exceed all communicable, maternal and perinatal nutrition-related deaths combined and represent an emerging global health threat. Every year, NCDs kill 9 million people under 60 years of age. The socio-economic impact is staggering. These NCD-related deaths are caused by chronic diseases, injuries, and environmental health factors. Important risk factors for chronic diseases include tobacco, excessive use of alcohol, an unhealthy diet, physical inactivity, and high blood pressure.

The world now suffers from a global epidemic of poor lifestyle choices! Medically we call them chronic illnesses or NCD's, but the issue at hand is that they can be avoided, reversed and prevented; with smarter lifestyle choices. The why and the how of these lifestyle choices is a debate for another blog, but poor socioeconomic conditions, poverty, malnourishment and diets deficient in basic nutritional building blocks all form part of this dynamic.

These poor lifestyle choices and the death, illness, and disability they cause will soon dominate health care costs and should be causing public health officials, governments and multinational institutions to rethink how they approach this growing global challenge. To exacerbate the matter; the deaths, illnesses and disability are spiralling at even faster rates in the developing world, where the infrastructure is even weaker than in the developed world.

It is estimated that by 2020 the number of people who die from ischemic heart disease will increase by approximately 50% in countries with established market economies and formerly socialist economies, and by over 100% in low- and middle-income countries. Similar increases will also be found in cerebrovascular disease (Stroke) by 2020!

This is indeed a frightening prospect; NCDs are expected to account for 7 of every 10 deaths in the world! The overextended healthcare systems in Africa and Asia will battle to cope with these spiralling patient numbers.

A (positive) point to ponder as we consider this bleak outlook; the principal known causes of premature death from NCDs are tobacco use, poor diet, physical inactivity, and harmful alcohol consumption – all of these are preventable and manageable; as they relate to personal choices. Therefore we need to focus on creating a environment where these same individuals can make the correct choices which will have a positive impact on their lives. This is where governments, aid agencies and multi-nationals should focus their energies, and the approach should be more carrot than stick, which is not the case at present.
