What posts are most read

Brain, cancer and health predominate my posts. I want to find the root causes of chronic diseases. After 40 years, my BFF lost one of her legs. I asked her if she is still drinking soda, and she replied that she stopped drinking many years ago. Before 40 years passed by, I know that she feel cold easy and had skin health issues. We now know that skin health issues are related to some organs such as kidneys, liver and lungs. And we also know that cancer cells feed on sugar.

Our thyroid and reproductive organs affect our control of temperature. And the pituitary gland is responsible for sex hormones, sleep, food cravings, stress hormones and other functions.

Do drink clean water and avoid toxins. Always eat whole foods, washed with salt or diluted vinegar water.

Different trajectories for different diseases

A century ago, death was typically quite sudden, and the leading causes were infections, accidents, and childbirth. Today sudden death is less common, particularly in Western, economically developed, societies. Towards the end of life, most people acquire a serious progressive illness—cardiovascular disease, cancer, and respiratory disorders are the three leading causes—that increasingly interferes with their usual activities until death.

Three distinct illness trajectories have been described so far for people with progressive chronic illnesses (fig 1)26: a trajectory with steady progression and usually a clear terminal phase, mostly cancer; a trajectory (for example, respiratory and heart failure) with gradual decline, punctuated by episodes of acute deterioration and some recovery, with more sudden, seemingly unexpected death; and a trajectory with prolonged gradual decline (typical of frail elderly people or people with dementia).

Summary points

Three typical illness trajectories have been described for patients with progressive chronic illness: cancer, organ failure, and the frail elderly or dementia trajectory

Physical, social, psychological, and spiritual needs of patients and their carers are likely to vary according to the trajectory they are following

Being aware of these trajectories may help clinicians plan care to meet their patient’s multidimensional needs better, and help patients and carers cope with their situation

Different models of care may be necessary that reflect and tackle patients’ different experiences and needs

We now consider each of these three trajectories in more detail.

Trajectory 1: short period of evident decline, typically cancer

This entails a reasonably predictable decline in physical health over a period of weeks, months, or, in some cases, years. This course may be punctuated by the positive or negative effects of palliative oncological treatment. Most weight loss, reduction in performance status, and impaired ability for self care occurs in patients’ last few months. With the trend towards earlier diagnosis and greater openness about discussing prognosis, there is generally time to anticipate palliative needs and plan for end of life care. This trajectory enmeshes well with traditional specialist palliative care services, such as hospices and their associated community palliative care programmes, which concentrate on providing comprehensive services in the last weeks or months of life for people with cancer. Resource constraints on hospices and their community teams, plus their association with dying, can limit their availability and acceptability. Box 1 illustrates this trajectory.

Trajectory 2: long term limitations with intermittent serious episodes

With conditions such as heart failure and chronic obstructive pulmonary disease, patients are usually ill for many months or years with occasional acute, often severe, exacerbations. Deteriorations are generally associated with admission to hospital and intensive treatment. This clinically intuitive trajectory has sharper dips than are revealed by pooling quantitative data concerning activities of daily living.4 Each exacerbation may result in death, and although the patient usually survives many such episodes, a gradual deterioration in health and functional status is typical. The timing of death, however, remains uncertain. In one large study, most patients with advanced heart failure died when expected to live for at least a further six months.8 Many people with end stage heart failure and chronic obstructive pulmonary disease follow this trajectory, but this may not be the case for some other organ system failures. Box 2 illustrates this trajectory.

Trajectory 3: prolonged dwindling

People who escape cancer and organ system failure are likely to die at an older age of either brain failure (such as Alzheimer’s or other dementia) or generalised frailty of multiple body systems.7

This third trajectory is of progressive disability from an already low baseline of cognitive or physical functioning. Such patients may lose weight and functional capacity and then succumb to minor physical events or daily social “hassles” that may in themselves seem trivial but, occurring in combination with declining reserves, can prove fatal.9,10 This trajectory may be cut short by death after an acute event such as a fractured neck of femur or pneumonia. Box 3 illustrates this trajectory.

Clinical implications

Trajectories allow us to appreciate that “doing everything that can be done for a possible cure” may be misdirected.

Optimising quality of life before a timely, dignified, and peaceful death are the primary aims of palliative care. Understanding and considering trajectories may help professionals take on board, at an earlier stage than would otherwise be the case, that progressive deterioration and death are inevitable. Before the terminal stages of a disease, some health professionals may allow the reality of the prognosis to remain unconsidered or unspoken, unwittingly colluding with patients and relatives in fighting death to the bitter end.11 Patients often want palliative oncological treatment even if it is extremely unlikely to benefit them, and doctors usually offer it to maintain hope as well as to treat disease.12 An outlook on death and expectations that are more acquiescent to reality may moderate the “technological imperative,” preventing unnecessary admissions to hospital or aggressive treatments. A realistic dialogue about the illness trajectory between patient, family, and professionals can allow the option of supportive care, focusing on quality of life and symptom control to be grasped earlier and more frequently. Figure 2 illustrates how the idea that palliative care is relevant only to the last few weeks of life is being replaced with the concept that the palliative care approach should be offered increasingly alongside curative treatment, to support people with chronic progressive illnesses over many years.

Box 1: Example of a cancer trajectory

CC, a 51 year old male shop assistant, complained of night sweats, weight loss, and a cough. An x ray initially suggested a diagnosis of tuberculosis, but bronchoscopy and a computed tomography scan revealed an inoperable, non-small cell lung cancer. He was offered and accepted palliative chemotherapy when he had already lost considerable weight (too much to allow him to enter a trial). The chemotherapy may have helped control his breathlessness, but he was subsequently admitted owing to vomiting. Looking back, CC (like several other patients in our study) expressed regret that he had received chemotherapy: “If I had known I was going to be like this….” His wife felt they had lost valuable time together when he had been relatively well.

CC feared a lingering death:

“I’d love to be able to have a wee turn-off switch, because the way I’ve felt, there’s some poor souls go on for years and years like this, and they never get cured, I wouldn’t like to do that.”

CC’s wife, in contrast, worried that her husband might die suddenly: “When he’s sleeping, I keep waking him up, I am so stupid. He’ll say, `Will you leave me alone, I’m sleeping.’… He’s not just going to go there and then, I know, but I’ve got to reassure myself.”

CC died at home three months after diagnosis, cared for by the primary care team, night nurses, and specialist palliative care services. His death had been discussed openly. He and his wife were confident that nursing, medical, and support staff would be available.

Box 2: Example of an organ failure trajectory

Mrs HH, a 65 year old retired bookkeeper (photo), had been admitted to hospital several times with cardiac failure. She was housebound in her third floor flat and cared for by a devoted husband who accepted little help from social work or community nursing. Previously she had been very outgoing, but she then became increasingly isolated. Her major concern was that her rapidly deteriorating vision because of diabetes prevented her completing crosswords, not that she had stage IV heart failure. Her treatment included high dose diuretics and long term oxygen therapy. She required frequent blood tests.tests.

She had raised her prognosis indirectly with her general practitioner, by mentioning to him that her grandson had asked her if she would be around at Christmas. Prognostic uncertainty was a key issue for many heart failure patients and their carers in our study, as illustrated by the following quotations.

  • “I take one step forward, then two steps back.” 84 year old, male, retired engineer, living alone, several recent admissions to hospital.
  • “I’d like to get better, but I keep getting worse.” 72 year old widow, living alone, psoriasis and arthritis.
  • “Things I used to take for granted are now an impossible dream.” 75 year old man, large family nearby, recently celebrated 50th wedding anniversary.
  • “There were times last year, when I thought I was going to die.” 77 year old woman, living alone, several periods in hospital with acute breathlessness.
  • “It could happen at any time.” Wife of 62 year old former footballer and taxi driver.
  • “I know he won’t get better, but don’t know how long he’s got.” Wife of 77 year old retired flour mill worker with severe asthma.

Mrs HH died on the way home from a hospital admission due to a nosebleed. She had had these occasionally as she had hypertension and a perforated nasal septum. Attempted resuscitation took place in the ambulance. Her husband later expressed deep regret that his wife’s clear wish not to have her life prolonged was not respected.

Box 3: Example of frailty trajectory

Mrs LC, a 92 year old widow, lives alone in a ground floor flat in central Edinburgh.Edinburgh.

Figure 3

Bereaved 12 years ago, she is now housebound due to arthritis and general physical frailty.

She used to venture out occasionally to the shops but over the years has felt less able and confident, largely because of a fear of falling. She appreciates the chair and walking aids supplied by the occupational therapist as these provide support and a sense of security at home. Since a “little fright” she had before Christmas when her legs gave way, she retires to bed earlier than before.

She receives regular visits from friends and the local church and is undemanding of services. Current medications are paracetamol, thyroxin, and bendrofluazide (for hypertension) and an annual influenza vaccine.

Mrs LC understands her current trajectory in terms of gradual decline in activities that she is able to do, and she is concerned that she might one day lose her independence. She has no relatives but is supported by her trust in God, who has “given me a good while on the planet, and should be sending for me now.”

Trajectories allow practical planning for a “good death”

Dying at home is the expressed wish of around 65% of people at the beginning of the cancer and organ failure trajectories.13 An appreciation that all trajectories lead to death, but that death may be sudden (particularly in patients following trajectory 2), makes it evident that advanced planning is sensible. Eliciting the “preferred place of care” is now standard in some palliative care frameworks and helps general practitioners plan for terminal care where the patient and family wish. This may increase the likelihood of patients dying in the place of their choice, as was the case for CC (see box 1).

Sensitive exploration is needed and can allow issues such as resuscitation status to be clarified and “unfinished business” to be completed for patients on all these trajectories. However, advance directives may be ignored in the heat of the moment.14 Mrs HH’s death had (unusually in people with heart failure) been planned, but an emergency overtook the situation and she received inappropriate resuscitation as documentation was not at hand. Living wills (advance directives) may be becoming more popular with patients, but most primary care professionals still have relatively little experience with these (Polack C, personal communication, 2004). Such planning may be particularly relevant to people in the third trajectory, where progressive cognitive decline is common.

Understanding the likely trajectory may be empowering for patient and carer

Some patients attempt to gain control over their illness by acquiring knowledge about how it is likely to progress.15,16 Had CC (box 1), who had lung cancer, been aware of his likely course of decline he might have been less worried about a very protracted death. Similarly, his wife might have been less worried about a sudden death. Both gave clear cues in the research interviews that they were concerned about the possible nature of the death and would have welcomed sensitive discussion of this with health professionals.

Limitations of the trajectory approach

The trajectory approach gives a conceptual overview, but patients must not be simply slotted into a set category without regular review. Individual patients will die at different stages along each trajectory, and the rate of progression may vary. Other diseases or social and family circumstances may intervene, so that priorities and needs change. Some people cope by denial or disavowal, making open communication less appropriate in the earlier stages.17

Some illnesses might follow none, any, or all of the trajectories: a severe stroke could, for example, result in sudden death or a fairly acute decline as in trajectory 1; a series of smaller strokes and recovery could mimic trajectory 2; while a gradual decline with progressive disability could parallel trajectory 3. Renal failure might represent a fourth trajectory consisting of a steady decline, with the rate of decline dependent on the underlying pathology and other patient related factors such as comorbidity.2 Patients with multiple disorders may have two trajectories running concurrently, with the more rapidly progressing trajectory typically taking centre stage. This is not uncommon in older patients with slowly progressive cancers.

Other dimensions of needs may have different trajectories

The trajectories we have considered relate to physical wellbeing. Other trajectories may exist regarding dimensions such as the spiritual or existential domain. In cancer patients, we have noted that spiritual distress and questioning may peak at diagnosis, again at the time of recurrence, and then later during the terminal stage. Spiritual distress in people with heart failure may, in contrast, be evident more uniformly throughout the trajectory, reflecting the gradual loss of identity and growing dependence.18 Psychological and social trajectories may also potentially be mapped. In dementia, the loss of cognitive function may cause parallel loss in activities of daily living, social withdrawal, and emotional distress.

Implications for service planning and development

One size may not fit all

Different models of care will be appropriate for people with different illness trajectories. The typical model of cancer palliative care might not suit people who have a gradual, progressive decline with unpredictable exacerbations.

People with non-malignant disease may have more prolonged needs, but these are as pressing as those of people with cancer. Uncertainty about prognosis should not result in these patients, and their families, being relatively neglected by health and social services.3,4 A strategic overview of the needs of and services available to people on the main trajectories may help policies and services to be better conceptualised, formulated, and developed to consider all people with serious chronic illnesses.

Planning care in advance may prevent admissions

Planning care and providing resources in advance on the basis of these trajectories might help more people die where they prefer. For example, many frail elderly and patients with dementia are currently admitted to hospital to die when terminally ill. The use of end of life care pathways in nursing homes is proving increasingly effective in preventing such admissions.13

Transferable lessons

Models of care for one trajectory may inform another. For example, cancer care can learn from the health promotion paradigm already established in the management of chronic diseases. Improving living while near death in North America19 and “health promoting palliative care” in Australia are two such examples. These have the potential to destigmatise death and maximise cancer patients’ quality of life right up to death. Conversely, patients with organ failure could benefit from ideas developed in cancer care, such as advanced care planning frameworks and end of life pathways.20,21

There are striking similarities between the burden of symptoms at any time of patients dying of cancer and those dying of non-malignant cardiorespiratory disease.22 Hospital palliative care teams, through offering specialist advice and sharing care with other specialists, can improve the care of many non-cancer patients.23


The key to caring well for people who will die in the (relatively) near future is to understand how they may die, and then plan appropriately. Since diseases affect individuals in different ways, prognosis is often difficult to estimate. None the less, it seems that patients with specific diseases and their carers often have common patterns of experiences, symptoms, and needs as the illness progresses. The notion of typical or characteristic trajectories is therefore conceptually sustainable and borne out in our longitudinal qualitative studies. Three typical trajectories have been described so far, and others may be characterised soon. More research is now needed to help understand how the insights offered by these trajectories can be translated into improvements in outcomes for patients and their families.

In Hippocrates’ day, the physician who could fore-tell the course of the illness was most highly esteemed, even if he could not alter it.24 Nowadays we can cure some diseases and manage others effectively. Where we cannot alter the course of events we must at least (when the patient so wishes) predict sensitively and together plan care, for better or for worse.

Gut Bacteria Linked to Age Related Conditions

Gut Bacteria Linked to Age Related Conditions

Source: Frontiers.

A new study shows for the first time that gut bacteria from old mice induce age-related chronic inflammation when transplanted into young mice. Called “inflammaging,” this low-grade chronic inflammation is linked to life-limiting conditions such as stroke, dementia and cardiovasuclar disease. The research, published today in open-access journal Frontiers in Immunology, brings the hope of a potentially simple strategy to contribute to healthy ageing, as the composition of bacteria in the gut is, at least in part, controlled by diet.

“Since inflammaging is thought to contribute to many diseases associated with ageing, and we now find that the gut microbiota plays a role in this process, strategies that alter the gut microbiota composition in the elderly could reduce inflammaging and promote healthy ageing,” explains Dr Floris Fransen, who performed the research at the University Medical Center Groningen, The Netherlands. “Strategies that are known to alter gut microbiota composition include changes in diet, probiotics, and prebiotics.”

Previous research shows that the elderly tend to have a different composition of gut bacteria than younger people.

Immune responses also tend to be compromised in the elderly, resulting in inflammaging.

Knowing this, Fransen and his team set out to investigate a potential link.

The scientists transferred gut microbiota from old and young conventional mice to young germ-free mice, and analysed immune responses in their spleen, lymph nodes and tissues in the small intestine. They also analysed whole-genome gene expression in the small intestine.

All results showed an immune response to bacteria transferred from the old mice but not from the young mice.

The results suggest that an imbalance of the bacterial composition in the gut may be the cause of inflammaging in the elderly. Imbalances, or “dysbiosis” of gut bacteria results in “bad” bacteria being more dominant than “good” bacteria. An overgrowth of bad bacteria can make the lining of the gut become more permeable, allowing toxins to enter the bloodstream where they can travel around the body with various negative effects.

Dysbiosis can have serious health implications: several disorders, such as inflammatory bowel disease, obesity, diabetes, cancer, anxiety and autism are already linked to the condition.

“Our gut is inhabited by a huge number of bacteria” explains Fransen. “Moreover, there are many different kinds of bacterial species, and the bacterial species that are present can vary a lot from person to person.”


Maintaining a healthy gut microbiota is clearly important to a healthy body and healthy ageing, but why the gut microbiota is different in the elderly is not fully understood. Many people are aware of the effect a course of antibiotics can have on the digestive system for example, but as Fransen explains, it may not be down to just one thing: “It is likely a combination of factors such as reduced physical activity, changes in diet, but also as part of a natural process.”

Most, if not all, age-related diseases can be linked back to inflammaging. Despite the fact that this particular study was conducted on mice, it is clear that maintaining a healthy gut microbiota is key to a healthy lifestyle. However, more research is needed to confirm that the human body mirrors the mice in this study.

“Both in humans and mice there is a correlation between altered gut microbiota composition and inflammaging, but the link between the two remains to be proven in humans” concludes Fransen.

Aged Gut Microbiota Contributes to Systemical Inflammaging after Transfer to Germ-Free Mice

Advanced age is associated with chronic low-grade inflammation, which is usually referred to as inflammaging. Elderly are also known to have an altered gut microbiota composition. However, whether inflammaging is a cause or consequence of an altered gut microbiota composition is not clear. In this study, gut microbiota from young or old conventional mice was transferred to young germ-free (GF) mice. Four weeks after gut microbiota transfer immune cell populations in spleen, Peyer’s patches, and mesenteric lymph nodes from conventionalized GF mice were analyzed by flow cytometry. In addition, whole-genome gene expression in the ileum was analyzed by microarray. Gut microbiota composition of donor and recipient mice was analyzed with 16S rDNA sequencing. Here, we show by transferring aged microbiota to young GF mice that certain bacterial species within the aged microbiota promote inflammaging. This effect was associated with lower levels of Akkermansia and higher levels of TM7 bacteria and Proteobacteria in the aged microbiota after transfer. The aged microbiota promoted inflammation in the small intestine in the GF mice and enhanced leakage of inflammatory bacterial components into the circulation was observed. Moreover, the aged microbiota promoted increased T cell activation in the systemic compartment. In conclusion, these data indicate that the gut microbiota from old mice contributes to inflammaging after transfer to young GF mice.
