Disease - Science topic

A disease is an abnormal condition that affects the body of an organism. It is often construed as a medical condition associated with specific symptoms and signs. It may be caused by factors originally from an external source, such as infectious disease, or it may be caused by internal dysfunctions, such as autoimmune diseases.

Background Summary:
Poverty, disease, and hunger remain among the most persistent and devastating challenges facing humanity. Despite significant advancements in science, technology, and medicine, these issues continue to affect billions worldwide, hindering progress and well-being for millions. What if science could be harnessed not just to mitigate these issues but to eradicate them entirely?
Recent breakthroughs in various fields—such as biotechnology, renewable energy, artificial intelligence, and social sciences—offer unprecedented opportunities to tackle the root causes of poverty, hunger, and disease in innovative ways. Can we leverage these advancements to design systems of resource distribution, healthcare, and education that are sustainable and equitable for all? Can biotechnology revolutionize food production and health solutions, while AI and data analytics create efficient, scalable models for poverty reduction?
Relevant answer
Answer
Can AI help to end poverty?
"Quashing poverty requires knowing who is in need and what their needs are, but collecting those data has long been a time-consuming and costly challenge. Some researchers are turning to artificial intelligence (AI) tools to help plug the gaps. AI can be biased, and could miss people without a digital trail. On the other hand, it can analyse a larger, more representative portion of the population than do household surveys, and identify patterns in data that even specialists could miss, says development economist Ariel BenYishay..."

To interject some reality into current U.S. government actions on NIH research overhead, I seriously doubt there are any biomedical research efforts of any useful quality in the US that could function on 15% overhead. This 15% idea sounds good to those who know little about research, but unfortunately it goes against facts, reason, logic, and law.
The various NIH requirements for accounting and many other compliance rules likely cost far more than 15%. Furthermore, buildings need to be heated, cooled and maintained. People need to be hired and managed. Cold rooms, warm rooms, and equipment need power and computing infrastructure. Most companies estimate their overhead on research as ~100%, and this is in fact the overhead charged at US National labs subject to lengthy DOE negations. So an enforced change to 15% NIH overhead would mark the end of quality US biomedical research as we know it now.
If the US remains a country of laws, then I predict that this 15% notion cannot happen any time soon. Legally this is an unconstitutional act as it changes congress appropriations and illegally breaks negotiated contracts for funded grants. If laws do not matter here, then Texas has thrown away billions for CPRIT and any meaningful cancer research will largely be done in other countries. Time will tell but statements made by current US leadership have not proven durable.
Near term, I guess that a 15% enforced overhead will mean the loss of our top scientists. This will cost the US many orders of magnitude more than the overhead they imagine saving somehow. Of course, this would also quickly end the pipeline from innovative research to products for US companies and be a boon to US competitors while losing billions in biomedical economy for the U.S. Perhaps money will speak if laws do not?
What do you think?

You don’t just “get” a given level of overhead costs, you have to negotiate them. Setting an arbitrary low number doesn’t help anyone.

Answer
Epigenetics refers to the study of changes in gene expression that do not involve alterations to the underlying DNA sequence. This field has garnered significant attention for its potential to influence aging, combat diseases, and mitigate unwanted side effects of genetic engineering.
Aging is associated with various epigenetic changes, such as DNA methylation and histone modifications, which can lead to altered gene expression and contribute to age-related diseases like cancer and neurodegenerative disorders. By targeting these epigenetic modifications, researchers believe it may be possible to reverse or slow down the aging process. For instance, interventions that modify epigenetic markers could potentially restore youthful gene expression patterns, thereby improving cellular function and longevity.
Epigenetic therapies hold promise for treating a range of diseases. By understanding the specific epigenetic alterations associated with conditions like cancer, researchers can develop targeted therapies that either activate or repress certain genes without changing the genetic code itself. This approach could lead to more effective treatments with fewer side effects compared to traditional genetic engineering methods, which often involve irreversible changes to the genomeOne of the significant concerns with genetic engineering is the potential for unintended consequences, such as off-target effects or the activation of harmful genes. Epigenetic modifications can provide a more flexible approach to gene regulation, allowing for temporary changes that can be reversed if necessary.
This flexibility could help in fine-tuning therapeutic interventions, reducing the risk of adverse effects associated with permanent genetic alterations.

How can personalized lifestyle modifications, including diet, exercise, stress management, and sleep hygiene, be integrated into conventional medical treatments to optimize health outcomes and potentially reverse or manage chronic diseases or any other diseases in the past, present or in the future?
Relevant answer
Answer
We can no longer rely on the philosophy of determinism (control) of classical science.They only apply to invariant properties of physics; not to society/biology/ecology.The models of classical science become deadly if used on medicine (health care).
Our participation in creation operates in our body, as human AND humanity. Science is incapable to describe that; the same is the case for any religion. But we can all experience it in our body: it is based on this uniVersal dynamic.
Integral Health Care makes use of all the healing arts of the whole Earth. East & West, Far-East & Far-West therein logically complement each other. Together they define and form Integral Health Care.
Together they can prevent, early-detect/correct, cure and palliate.
The essence is simple:
  • The West created an anatomic (“somatic”) structural understanding of our body.This bases itself on the Classical models of deterministic science.
  • The East (Ayurveda) focused on supporting the physiological processes of our body.This calls for a Relativistic type of thinking.
  • The Far-East (Acupuncture) designed an approach to recalibrate the regulatory system of our body.This requires a Probabilistic approach.
  • The Far-West (Spiritual Healing) works primarily with the Information Integration system of the body.This calls for a universal integral/unified Field description.
  • The principles and method for integration of these forms of healing is found in our living body. Our body is not a mechanical object: it is an information processor which interacts with its context. In our living being, information integrates with matter, with the essence of life: Freedom of Choice. Our body is our best example on the way objective reality is based on subjective realisation. Realise that the scientific model of reality changed from Determinism to Relativity to Probability to Creativity. Our participation in creation means that our reality is based on our realisation. Especially for health care this means a change from Objectivity to Subjectivity: “what you think matters”.

I'm interested in studying specific missense mutations in a human gene. My goal is to determine whether the mutated region of the protein is conserved across various species. Could you please guide me on how I can use in silico tools to find homologous protein sequences and identify their conserved regions?
Thank you very much
Relevant answer
Answer
That's a good approach Susanta Roy I would add that once you are working with your multiple sequence alignment (MSA) in Jalview (https://www.jalview.org), you load an experimental 3D protein structure, or an AlphaFold model (all possible from Jalview, just right-click on a sequence label), and visualise the mutations and conservation scores on the structure too. Jalview makes this easy by colouring the structure by the sequence, so you can choose to colour by conservation and add features to represent your mutations and they will instantly be viewable on the structure.
The other thing I would add is that in addition to BLASTing the full-length protein, have a look at it on InterPro and see what domains it has. Then you can work with curated MSAs from the individual domains too.

I'm writing a review article in which I explain the different mechanisms by which M. tuberculosis reaches a persistent infection by establishing a cross-signal homeostasis with its host, in which both organisms modulate their actions and reactions towards the other one, and at some part I came up with this sentence " This thought provoking notion makes me think of its similarity to Newton’s third law of motion; a system reaches a steady state whenever the forces acting upon it are equal and opposite one another". How prudent is that?
What do you think about it? :)
Relevant answer
Answer
The two critical words in the Third Law are 'equal' and 'opposite'. The essence of 'Opposite' may be perceived well in various biological systems.
As pieces of exemplary shreds of evidence, in cancer therapeutics, tumor exerts strong pro-tumor response against applied treatment and imposes therapeutic resistance, one of the major problems seen in preclinical and clinical studies. The same goes for the multidrug resistance in various medically relevant bacteria.
However, measuring/gauging the essence of 'equal' may be a bit difficult task in biological systems.
AFTERALL, BIOLOGY IS A SCIENCE OF EXCEPTION. The rules of physics/chemistry may be applied directly in some cases while in others, they might seem to be bit 'diluted' or rather entwined with greater intricacy... reason: living systems are not isolated systems, which are often considered for the derivation of the rules/laws of physics and chemistry. It is not about the violation of the rules/laws... rather a manifestation of the same in different perspectives- unexplored/unexplained milieu...

Answer
Dear Bhoj P. Singh,
No government in India has successfully formulated policies to manage the country's human population growth, which stands at 1.6% a year, down from a high of about 2.3% in the early 1970s. India is forecast to become the world's most populous country in 2030, up from 1.35 billion today to nearly 1.55 billion. The two main common causes leading to over population in India are: The birth rate is still higher than the death rate. The fertility rate due to the population policies and other measures has been falling but even then it is much higher compared to other countries. The formation of a national Indian planning commission for population control is viewed as necessary for motivating all people to reduce population size. More statistics are needed in India on environmental measures and population. Environmental degradation lowers economic status, which in turn contributes to poverty. According to a report in the Times of India (6 May 2010) the government of India will not introduce legislation to reduce population growth. Report said, “Population is a major concern. India is the world's second most populous country. Urgent steps need to be taken to stabilise the population for sustainable development.”
Below are the most effective measures which can be employed to control population growth:
1. Development.

Coffee farmers in the Philippines have had a tough time over the past few decades with the decline of coffee plantations across the archipelago. This has driven them oftentimes to sell their best beans and consume the damaged or scrapped ones.
I'm currently looking into studying the effects of this by analyzing the blood of renal disease-afflicted coffee farmers from different regions of the Philippines for Ochratoxin A, which is produced by Aspergillium and Penicillium species that grow on damaged coffee beans.
As far as my research has shown, the correlation between ochratoxin A and renal disease in humans or primates is yet to be studied. Any help finding pre-existing research regarding this topic would be much appreciated.

"As far as I know, viruses are self-replicating structures, using for this purpose nucleic acids identical in function to those present in living cellular organisms. They can therefore be regarded as living - and virology is indeed a branch of biology. "
My understanding is that viruses and viroids (not mentioning prions) are non-living since they are metabolically inactive and unable to reproduce outside a host. Some virologist even refer to them as infectious agents and not organisms.
Is this still a debate that requires clarification or have we come to some sort of consensus?

It is a common trend of cultures to marry within own blood relations. Do you think it may be harmful to the children of such couple or their next generation?
Please explain only scientific views and research reports.
Relevant answer
Answer
Dear Shibabrata Pattanayak , different studies revealed that children born from parents who were closely related increases the risks of having a baby with potentially life-threatening birth defects.
Marrying within a family can lead to abnormalities in your future offspring. This is because within a family, certain genetic traits remain dormant and are known as recessive genes (they are not seen as a disease or condition).
When two people having the same genes marry and reproduce, these once dormant recessive (ineffective) genes double, making them more likely to cause genetic abnormalities in children.
Although, the fact that people who marry within the second generation are more susceptible is fairly true. But for eg. If your grandfather and parents have had marriages within the family, your children are at greater risk due to the overcrowding of the gene pool.
To explain better, think of it this way. If your grandfather had some recessive genes and he married someone in the family with those same recessive genes i.e. those once dormant genes become dominant (more likely to cause genetic abnormalities). Your parents then got married within the same family making the concentration of these recessive genes even more. Now when you marry someone within your family, this gene pool will further become dense with recessive genes, due to both your genes getting added to the pool, making the possibility of your children having genetic abnormalities very high.

An autoimmune disease is a condition in which the immune system mistakenly attacks the body. Are there any scientific reasons explaining why the body acts abnormally in this way and are there any special treatments for these diseases?
Relevant answer
Answer
My understanding is that autoimmunity occurs when a positive feedback loop arises within the B cell compartment that overrides T cell control. Positive feedback is to be expected in B cells because antibody production needs to be a chain reaction. Positive feedback is normally blocked for self antigens but there are a variety of reasons why a feedback loop for self antigens might arise - different for each antigen. In each case a specific subversive signalling mechanism is implicated. My viewpoint is published in an article in Immunology 1999, Edwards JCW, Cambridge G and Abrahams V. It should come up on Pubmed or Google easily. It was this viewpoint that led us to introduce rituximab to deplete B cells in non-haematologic disease - initially rheumatoid and lupus and then other conditions. Rituximab is highly effective in many autoimmune conditions but fails if autoantibody producing plasma cell clones are too long lived or permanent tissue destruction has already occurred.

Relevant answer
Answer
The conclusion about the diagnosis depends on what you found. First, you need to verify the result. It is possible to do this by the method of sequencing by Sanger, one can use the PCR-RFLP method. Secondly, you need to see if there is a change in the parents, in the third, look at the database of data, whether this change is known as a pathogenic mutation. Then, if it is a mutation to analyze how it is inherited: dominant or recessive. If it does not exist in the databases, then, by forecasting programs, see that it is broken. And only after that draw conclusions. Sorry for my bad english.

how useful would you say genomic approaches is in this field in comparison to traditional methods used previously to identify pathogens?
Is it better for patient treatment for us to use genomic sequencing methods such as WGS/NGS? 
Does it help public health investigate outbreaks and make international surveillance easier?
Relevant answer
Answer
Dear Dr Ahmed
The short answer is yes. 
Genomics can be of use to identify an unknown pathogen. They can be used to trace the origin of an outbreak. They can with some difficulty be used to estimate the reproductive number. 
They can also be used to confirm/refute theories about the origins of an outbreak. C difficle is a problem in many hospitals. Although ribotyping suggested a common epidemic strain, further sequencing has shown that there are multiple strains circulating. Another example is MRSA. Although these strains have similar phage profiles, biotypes and resistance patterns there are multiple strains in circulation rather than one or two epidemic types. Finally a paper recently reported the results of an investigation into an extended beta lactam resistant Klebsiella pneumonia that has persisted for a several years. On analysis it was found that the strain had originated several years before it was detected in the hospital. 
All this having been said isolating the genome of an unknown pathogen can be difficult. This is at the moment not really sensible. Most labs are not set up to do this in real time so for the moment it seems we are stuck with the usual methods. There has been movement in this area for TB but the jury is still out on these for the moment. Inhibitors of PCR that are not allowed for in testing systems may produce false negatives or even worse false positives. All of that having been said it seems likely that these methods will become mainstream in the not too distant future. 
If urgent action is indicated the usual methods are probably the most reliable at the moment. When possible sequencing of the pathogens responsible should be done as this provides information that may be useful or even critical and cannot be obtained in any other way. For example say there is an outbreak of Salmonella at a party. Most food associated Salmonella have the same serology and phage type. While the usual methods of identification may suggest uncooked eggs (the usual suspect) legally this may be problematic given the similarities between Salmonella and the problems with growing them from the eggs days after the party. Genomic typing may even rule the eggs out as a source.

Surgical myectomy is highly effective in treating HOCM. Since the disease may present in different anatomic forms, those patients with more extensive disease pose surgical challenges. For instance, in those patients with apical and mid/apical hyperthrophy, surgery often requires a combined transaortic and transapical approaches. However, one may argue that a successful basal myectomy would be a safer and equally effective treatment, leaving untreated the mid septum and/or apical septum. What is the validity of this later argument, in terms of recurrent heart failure and sudden death?

Hypothetically apical hypertrophy can be managed by ablation of distal septal branches( or even Left Circumflex artery distal branches-theory no evidence present).

Answer
One possibility is that it is the result of a dominant negative effect (as Martin has elaborated), however, this is quite a rare phenomenon.
The other (more likely) possibility is the effect of excess heterozygosity in the control group and this will give a strong p-value when comparing HETs in cases vs controls. The best way to be sure that the association is NOT a false positive (as mentioned by Christian) is to check HWE in the control group and see if there is any significant deviation. If that is the case, one possible reason for this is the 'isolate breaking effect'; the control group does not represent a single random-mating population.
We have addressed this issue in our paper where we think false positive associations have been reported:

My feeling after serving 40 years in state government is you have a systems problem exacerbated by numerous issues I could not begin to understand.

These are very difficult tasks anywhere!!! The biggest systems in any country are the military, central government, law enforcement and the judicial system. In America our presidents have often  had fact finding hearings, which gave everyone a concise list of the issues, possible resolutions/interventions. Often time our presidents have called for a Presidential Summit on a particular issue where leaders in a particular area/discipline  gather to look at issues, develop solutions, consider law introduction or changes, and develop patterns of communication and consensus. I can only very humbly suggest  that health issues do belong to the local, regional governments but also is within the scope of the central government and may be a the cite to develop/change/collaborate on issues concerning the public health.  I hope I have been some small help to you and your country....Tom

However, if it is affecting the bird in any (negative) way, then it could be called an infection.
Any thought on this dilemma?
Relevant answer
Answer
Attila, you are coming to what I see as a language problem regarding how we think about our microbial ecosystem.  Infection is the 'older' word used which was quite understandable in the past with our limited understanding of our microbiota, even infections may generally be polymicrobial but instead we focus on one recognizable strain to determine our therapy.  Campylobacter may be a commensal at low (undetectable) levels early in life, but during the stressful times it overgrows and is shed because of its high numbers.  The better term for this is 'dysbiosis' which means a microbial imbalance, and implying that it is not a good situation even if we do not see a strong pathological impact.  We need to use this term more often for these imbalances and hope it catches on as it is probably more descriptive and correct than the usual meaning of infection.

I am in the process of identifying whether or not any correlations can be drawn between the the expression of genes and proteins. I know when studying the risk in diseased patients we often look to genomics to get a better understanding as to our predisposition to different diseases. With this being said, people are now finding proteomics to be a better indication of actual health. Is there anyway to define a correlation between gene expression and subsequent protein expression or are there too many moving pieces to effectively do so?
Relevant answer
Answer
Hi George,
Let's first define "gene expression". In its original sense, it refers to the full sequence of genetic processes (i.e. information transfer) from a gene to the molecular entity it codes for (either a protein or a noncoding RNA). If we are speaking about a protein-coding gene, gene expression should include transcription, mRNA maturation, export, translation and post-translational modifications. Sounds like a lot of steps. This is basically the reason why in eukaryotes the correlation between transcription and protein abundance is very low. Post-transcriptional regulation at each step is responsible for this lack of agreement. As post-transcriptional regulation is normally gene-specific, there is no easy way to account for it globally: at the present stage, we simply cannot reliably predict how much protein will be produced from an mRNA with a given abundance.
This is why proteome, which is the final product of the cellular gene expression, provides more direct information about possible molecular mechanisms of a disease, whereas transcriptome is just a proxy.

Relevant answer
Answer
Hi
selection of controls is the most important point in case control studies. 
•The way of control selection determines:  What is estimated (risk ratio, rate ratio, odds ratio) and the validity of estimate.
Three basic tenets of comparability underlie attempts to minimize bias in control
selection. These are the principles of study base, deconfounding, and comparable accuracy.
Comparable accuracy principle. The degree of accuracy in measuring the exposure
of interest for the cases should be equivalent  to the degree of accuracy for the controls, unless the effect of the inaccuracy can be controlled in the analysis.
Study base principle. Cases and controls should be "representative of the same base experience".
Deconfounding principle. Confounding should not be allowed to distort the estimation of effect.
in this case if you have many cases you can select them systematically but it is better you select the new cases. selecting of control is important. you must first identify the source population that cases arise from it. If your study is a population-based case-control study, that uses a primary base. when ascertainment of all cases in a primary base is difficult or impractical, it may be preferable to use a secondary base. The base is defined as the source of the cases, and controls are individuals who would have become study cases if they had developed disease 
during the time of the investigation. For example, in a hospital-based study, the
cases might be all patients diagnosed with the study disease at one hospital; the individuals contributing to the (secondary) base would be all subjects who would be diagnosed at that hospital had they developed the study disease. 
Finally i think purposive sampling without attention to source population of cases can disturb your results.

What methods are there to create new cutoffs for a given continous measurement as an indicator of health, or diagnosis of a disease? For example, how can I create new cutoffs for C-reactive protein as an indicator of severity of a disease (normal, mild, severe....)? To be specific, I am interested to know the methods for new cutoffs, not about the C-reactive protein per se.

Hello Henock,
By generating a ROC curve you could decide a clinically valid cutoff. It is generated using sensitivity and 1- specificity and plotted for different cutoffs. Hence this displays the tradeoff we make. The "shoulder" of the ROC can be used as the clinical cutoff. 
Hope this helps.

Hi,
I was just wondering how tight junctions contribute to the development of diseases and if there is any known connection between Claudin 6 expression in developmental programming and/or the development of metabolic diseases?
Any thoughts/ comments?
Thanks,
Pooja.

Answer
Oligodendrocyte-specific protein (OSP/claudin-11) is a four transmembrane protein concentrated in central nervous system myelin. Recent evidence has emerged suggesting that OSP/claudin-11 is involved in membrane interactions at tight junctions and with the extracellular matrix. OSP/claudin-11 seems to modulate proliferation and migration of oligodendrocytes presumably through these interactions. Furthermore, evidence is presented implicating OSP/claudin-11 as an autoantigen in the development of autoimmune demyelinating disease.

There are thousands of special classifications of symptoms, like NYHA, or psychiatric, or others. Most of them are related either to specific disease (group of diseases) or anatomic localization, or both. But I haven't succeeded in finding a universal approach for classification of existing symptoms according to their features, like specific/unspecific; subjective/objective/paraclinic; local/general, etc. There is part of ICD-10 (R00-R99), which tries to classify symptoms and Symptom classification by NCHS (was developed in 1974, see link to *.pdf file), but I didn't find any fresher. Does anybody know any universal symptom classification?

A terminology set called Medcin is one of the best for symptoms.

Rosai Dorfman's disease is the accumulation of histicytes in lymph nodes and sometimes in extra nodal regions of the human body. Treatment depends on the presenting symptoms, patient clinical state at presentation and the organ involvement. It may not require any treatment other than observation, sometimes may require surgery for airway divertion, may require the use of prednisolone or chemoradiation. I would like to know the current management of this disease besides those just mentioned above.

I realize this question may sound weird (to say the least)... but I was always wondering if one took all the reported literature cases for a specific disorder / disease (assuming that there would be 1,000's of them) -- would the collected sample actually approach the true disease population? Would there still be significant reporting bias? What do you think?

This website may partially already cover what you were thinking of 
I am also looking at bibliometrics to go alongside my research investments (see my pubs list for the general idea) work, so am ploughing through papers related to (for the moment, pneumonia, HIV, TB and malaria) that have a UK author. Will soon have an idea of numbers across different types of science there. Not specifically highlighting the case reports, but it will cover disease areas within infection.
