Morning Medtalks With Dr KK

1. Photons can behave like magnetic dipoles at absolute zero temperatures. This is the new result from a quantum simulator put forward by physicists at the EPFL in Switzerland and Paris Diderot University in France. The theoretical study proves that simple photonics devices can be used to mimic the behaviour of complex materials under extreme conditions experiments that are difficult to actually do in the laboratory.

2. HC refuses to hear plea on generic drugs: The Hindu: the Delhi High Court on Monday declined to entertain a petition seeking directions to the Centre and the Medical Council of India (MCI) to ensure that doctors prescribe generic medicines.

3. The Bombay High Court announced a judgement and ordered an institution to issue a diploma certificate to a woman without her husband's name. The woman divorced her husband and wanted to remove his name.

4. New evidence suggests that oxidative stress and DNA damage in sperm may contribute to repeated miscarriages in female partners, according to a small study presented here at ENDO 2019: The Endocrine Society Annual Meeting.


How long does a joint replacement last?

How long will my joint replacement last?

10 to 15 years on an average but in an individual rare complications requiring re-operation can occur soon after surgery; for others, a replaced joint can last two decades or more.

The subject is important to the person who is uncertain about whether joint replacement is worth pursuing. But in addition to whether to have surgery, these numbers can help people decide when to have it done. For example, a person in their 30s might be looking at two or more revisions. Some younger joint replacement surgery candidates have been advised to wait until symptoms are more severe in the hopes of reducing the need for multiple revisions in the future.

In February 2019, two large analyses were published in the medical journal Lancet regarding the longevity of replaced hips and knees, that included nearly 300,000 total knee replacements and more than 200,000 total hip replacements.

Nearly 60% of hip replacements lasted 25 years, 70% lasted 20 years, and almost 90% lasted 15 years.

Total knee replacements lasted even longer: 82% lasted 25 years, 90% lasted 20 years, and 93% lasted 15 years.

These estimates are quite a bit higher than prior ones and may reflect improvements in surgical technique and materials, general medical care around the time of surgery, or more aggressive mobilization and physical therapy that starts right after surgery.

These surgeries were performed in New Zealand, Australia, Denmark, Finland, Norway, and Sweden. The results might be different in the US or other countries.

Surgery is usually the last (and sometimes best) option


Tele nighshift ICUs

Hospitals can turn to telemedicine to fill physician gaps in nightshifts in intensive care units when a lack of subspecialists could mean the transfer of a patient to another hospital.

This model has efficiency benefits as per a study presented by Dr Mac McCormick President and chief executive officer of Eagle Telemedicine at the Society of Hospital Medicine 2019 Annual Meeting.

Remote physicians can provide backup for onsite nurse practitioners and physician assistants, saving money.

And specialists physicians can work for three or four places at the same time.

Tele-hospitalists can work from home offices and can be hired for a few hours or a whole shift. They have access to the electronic health record, admit patients, and order labs and tests.

When a doctor working remotely needs to see the patient, a telemedicine cart is wheeled into the room.

More than half of all hospitals in the United States use some form of telemedicine, according to the American Telemedicine Association.

  • Beware of Fake News: Always look for evidence of a story

    Yesterday was 1st April, which has customarily been celebrated as April Fool's Day. And practically, all of us have been inadvertently victims of a hoax or prank by a friend on this day, at some point of time or the other. But this was all good fun and in good spirits.
    But, now fake news or hoax is flooding the social media as it has become "the platform" for exchange of news or information, which can be either true or false....read more


    Nocturia may be a sign of high blood pressure

    Nocturia is not only caused by urinary problems but also by systemic diseases such as hypertension. Trips to the toilet at night are a sign of high blood pressure and/or excess fluid in your body, suggests a new study presented at the 83rd Annual Scientific Meeting of the Japanese Circulation Society (JCS 2019).
    The Watari study examined the association between nocturia and hypertension in residents of Watari who had an annual health check in 2017. Blood pressure was measured and information on nocturia was obtained by questionnaire....read more
