Ever since the Apollo missions, the health of astronauts have suffered long after their time in space was over. From decreased bone density to reduced muscles to cardiovascular harm, low gravity environments require a toll on the body. Lots of the astronauts’ ailments closely resemble conditions suffered by people of old age, from back pain to osteoporosis, the research of reduced gravity healthcare goes past astronauts alone.
Even with exercise routines developed to keep muscle mass and bone density, several astronauts complain of back pain lasting for years after their reduced gravity exposure. Dr. Jeffrey Lotz of UCSF has been studying the vertebrae of astronauts to understand that the origin of the issue and has been amazed by his results.
Though he thought the reason for pain would be water retention in discs, what might typically be pushed from them by bone compression due to gravity, rather he discovered a deterioration in the muscles which support the back bone known as the multifidus muscles.
Now, he’s working in communicating with NASA to look for a set of exercises that target those muscles while also thinking about the limitations of room to a spaceship and low gravity.
The exercises aren’t suitable for muscle health but include enhancing bone health. However, since Dr. Daniel Bickle discovered in mouse studies exercise alone is not sufficient to maintain bone density in space.
Based on his studies, the low gravity environment disturbs the signal procedure between osteoclasts and osteoblasts. In normal bone processes, bone is reinforced once damaged or placed under the persistent strain of walking round in the planet’s gravity. With these stressors found in low-gravity, osteocyte cells in bone tissue discover decreased stress in certain locations, subsequently sends an activation signal to reabsorb the additional bone tissue that is no longer will need to the osteoclasts. Once the work of the osteoclasts is completed, an additional signal is transmitted to osteoblasts, which rebuilds necessary bone.
Because the signal interruption is occurring in the later stage of the procedure, between the osteoclasts and osteoblasts, bone continues being consumed but does not get rebuilt while in space.
Astronauts with just six months spent on ISS possess a decreased bone density loss of six to nine percent, a loss equivalent to that typically seen annually in postmenopausal women. Although the astronauts may recover the bone density after a year spent in ordinary gravity, the bone material is redistributed in this way that their skeletal constructions resemble the elderly adult.
Dr. Bickle believes that further study into why this happens would not just help astronauts and heavy space travel but could also unlock treatments for osteoporosis.
Another factor leading to decreased bone density from astronauts is radiation exposure, but Dr. Bernard Halloran has discovered an intriguing solution for the reason for bone loss.
Even though it is uncertain why Dr. Halloran’s experiments with mice have proven that plum powder lessens the loss of bone due to radiation exposure. While further study is required to focus the mysterious active ingredient to pill form, it is a promising discovery for low-gravity healthcare.
Possibly the most detrimental of all of the effects of spaceflight , and aging is that the effect on the cardiovascular system. Over the years, Dr. Marlene Grenon has studied the effects of microgravity on astronauts, that frequently suffer from circulatory problems after returning to Earth also raises the chance of heart attack because they age.
Dr. Grenon and colleagues, Dr. Sonja Schrepfer and also Dr. Tobias Deuse, have discovered multiple variables influenced by the low gravity environment of space, including gene expression, cell functioning interference, and thinning vascular walls, which bring about the declining cardiovascular health of astronauts. Similar problems are evident from ordinary gravity cardiovascular disease victims.
Although not a problem on ISS, because astronauts come back to normal life on Earth, the impact in their health is detrimental (harmful) and long term. But Dr. Schrepfer’s team has discovered a molecule which may stop the avoidance of vascular walls and also hope to begin human trials soon.
In addition, Dr. Schrepfer will probably be studying the effects of space on the individual immune system like the work accomplished by Dr. Millie Hughes-Fulford, who’s been studying the issue since 2003.
At present, Dr. Hughes-Fulford has been studying gene expression from T-cells. Her studies have discovered that in reduced gravity five different miRNAs (microRNA), generally responsible for triggering the genes of T-cells, weren’t working. These adjustments, normally found in the elderly over a span of 30 decades, starting in astronauts, typically in the peak of health, after just 30 minutes in space.
So far, the sole mobile function researchers could come across that’s not negatively influenced by time spent in space is the procedure in which DNA fixes itself. Dr. Faith Karouia of both USCF along with Dr. Honglu Wu of NASA’s Johnson Space Center, have studied fibroblast cells from micro gravity environments compared to Earth bound cells also found no change regardless of the change in gravity or radiation.
Although more data is required for a complete conclusion, scientists hope the discovery may help research into the cancer cells live and self-heal via radiation therapy as well as help bolster astronaut health during space flight.
In general, low-gravity healthcare is a herculean undertaking across several medical areas and is vital to protect the long-term health of astronauts, especially as many agencies aim for deeper exploratory area travel. Moreover, the exact same medical breakthroughs have the potential to enhance medical care for the general population also significantly.

REUTERS: Many consequences for hospital patients — including how long they remain and their survival chances once they return — might depend on whether they’re cared for by their primary care doctor or another kind of physician, or a U.S. study indicates.
Researchers analyzed data on 560,651 admissions nationally for patients insured by Medicare, the U.S. health program for the elderly and disabled, who needed a wide variety of common clinical problems. Their hospital care has been overseen by one of 3 forms of general medicine doctors: their primary care doctor, a so-called hospitalist with special instruction in caring for psychiatric patients, or other generalists.
In comparison to patients observed by hospitalists, patients seen with their primary care physicians needed more expert consultations and more hospital stays, which can at times indicate less efficient care. However, these patients were more inclined to be discharged house instead of a rehab or nursing center, and they’re also less likely to die within 30 days of leaving the hospital.
“It’s likely that primary care physicians are not keen to release till they feel like there’s a more perfect plan for dwelling, which hospitalists are discharging previously, when individuals are clinically stable, with the premise that outpatient providers will operate on further refining the maintenance plan,” explained lead study author Dr. Jennifer Stevens of Harvard Medical School and Beth Israel Deaconess Medical Center in Boston.
The gap in survival outcomes is harder to explain, Stevens explained by email.
“We don’t know whether it is due to something that occurs in the hospital as a result of the primary care physician’s decisions, or due to a primary care physician’s presence in the hospital influences post-hospital maintenance,” Stevens added.
Hospitalists now outnumber any other specialization in internal medicine and also they care for about three in every four patients in U.S. physicians, researchers notice from JAMA Internal Medicine.
The hospitalist model of care has taken hold in the past few years as a means to shepherd increasingly sophisticated patients with numerous serious and chronic health problems through hospital remains. Because they know how things work inside the hospital, they could reevaluate evaluations, organize expert consultations, and work to enhance both the efficacy and quality of maintenance.
For the current study, researchers wanted to see if patient outcomes were distinct with hospitalists than using a primary care doctor or another general medicine physician that the individual did not already know.
Hospitalists cared for 60% of patients in the analysis, whereas primary care physicians saw 14 percent of their patients and other generalists treated 26 percent of their patients.
In comparison to hospitalists, primary care physicians used consultations 3 per cent more frequently as well as other generalists used consultations 6 per cent more frequently, the analysis found.
Lengths of hospital stays were 12 percent more using primary care physicians and 6 per cent more using other generalists than they were with hospitalists.
Primary care physicians were 14 percent more likely than hospitalists to release patients to their homes instead of institutional care settings, whereas generalists were 6 per cent less likely than hospitalists to do this.
Readmissions, or replicate hospitalizations, within one week or one month of release were like primary care physicians and hospitalists, however, happened more frequently with other generalists.
Patients cared for by primary care physicians were 6 per cent less likely to die within 30 days of release compared to people treated with hospitalists. However, with generalists, patients have been 9% more likely to die than with primary care physicians.
The research wasn’t a controlled experiment designed to establish whether or how the kind of physician treating hospital patients influences outcomes.
“This doesn’t show that the hospitalist model doesn’t work,” explained Dr. Seth Landefeld, author of an accompanying editorial and a researcher in the University of Alabama in Birmingham.
However, it does suggest there are advantages to sticking with one physician.
“A trusting relationship with a physician who will ‘orchestrate’ your care through the plan of sickness can be very valuable, as opposed to bouncing from 1 subspecialist into another without a ‘running’ physician,” Landefeld said via email.
Doctors chasing Indian systems of medicine, such as ayurveda, and antidepressant might be allowed to practice allopathy after having a bridge training course, according to a bill introduced in the Lok Sabha.
The National Medical Commission Bill, 2017, which attempts to replace the present apex medical instruction operator, the Medical Council of India (MCI)along with a new body, has been moved by the authorities in the House Friday.
Clause 49 of the Bill calls for a joint sitting of the National Medical Commission, the Central Council of Homoeopathy and the Central Council of Indian Medicine in least once a year “to enhance the connection between homoeopathy, Indian Systems of Medicine and contemporary systems of medicine”.
In addition, it has suggested that particular instructional modules or modules for developing bridges across the many systems of drugs and promotion of medical pluralism, may be carried out with the consent of all the members within the joint sitting.
“The combined sitting, can, by an affirmative vote of all members present and voting, select a particular bridge course that could be introduced for the professionals of Homeopathy and of Indian Systems of Medicine to enable them to prescribe such contemporary medicine at this level as may be prescribed,” based on the Bill. It provides for the ministry of four autonomous planks entrusted with conducting undergraduate and postgraduate instruction, evaluation and rating of healthcare institutions and registration of professionals under the National Medical Commission.
The commission will have a government-nominated chairman and associates, along with the board members will be selected by a search committee under the Cabinet Secretary, ” he states.
A 25-member commission will replace the chosen MCI, the Bill states.
The proposed measure has been strongly opposed by the Indian Medical Association (IMA) which maintained it will “cripple” the performance of medical profession making it completely answerable into the bureaucracy and non invasive administrators.
“Regulators will need to have an autonomy and be independent of their administrators. The National Medical Commission will be a regulator made by the administrators under their immediate management,” IMA’s president Aggarwal explained.
The Bill also proposes a frequent entrance exam and licentiate (leave) exam which all health care graduates will have to clear to get training licences. The licentiate (exit) examination is going to have to be coducted in three years after Parliament passes it.
A medical transcription company, like one member representing each state and Union land (vice-chancellors in both cases), the chairman, University Grants Commission, and the director of the National Accreditation and Assessment Council will make recommendations about the NMC.
According to CID sources, three more officials of the hospital, who were Also a part of the recruitment board when Alam was hired as Residential Medical officer (RMO), will be interrogated soon
