It's not just the lungs that get severely affected in coronavirus disease patients but also the heart. According to a new study, as many of 78% of Covid-19 patients monitored developed a heart condition, independent of pre-existing conditions, the Hindustan Times has reported. Published in the journal &lsquo;JAMA Cardiology&rsquo;, the study also found that 60% of the Covid-19 patients had an ongoing swelling of heart muscles. Data from about 100 recovered patients from the University Hospital, Frankfurt&rsquo;s Covid-19 registry between April and June 2020 was analysed for the study.

It's not just the lungs that get severely affected in coronavirus disease patients but also the heart. According to a new study, as many of 78% of Covid-19 patients monitored developed a heart condition, independent of pre-existing conditions, the Hindustan Times has reported. Published in the journal ‘JAMA Cardiology’, the study also found that 60% of the Covid-19 patients had an ongoing swelling of heart muscles. Data from about 100 recovered patients from the University Hospital, Frankfurt’s Covid-19 registry between April and June 2020 was analysed for the study.

Asymptomatic patients of Covid-19 carry the virus in equal measure, according to a new South Korean study published in the journal&nbsp;JAMA Internal Medicine.
While the researchers were not able to confirm how much virus these patients pass on, there is evidence to show that they do form a considerable part of the number of Covid-19 infections.
Results of 1,886 tests suggest people with no symptoms have the same amount of virus in their throat and nose, as a symptomatic patient.&nbsp;
It is less likely though that asymptomatic patients have a cough that will send infected droplets further into the air and transmit the virus.&nbsp;&nbsp;
&nbsp;

New research suggests that&nbsp;the loss of sense of smell reported by many Covid-19 patients might be due to inflammation triggered by the disease, and not directly caused by the viral infection.&nbsp;
Scientists&nbsp;analysed oral cells of adult mice and discovered that&nbsp;a protein which the novel coronavirus uses to enter host tissue is not present in the taste buds.
According to the study, published in the journal ACS Pharmacology &amp; Translational Science, other viruses that affect the taste buds, including the flu virus, might infect different tongue cell types.&nbsp;
While previous research had shown that SARS-CoV-2 enters human cells through the ACE2 receptor on the surface of some cells, including those of the human tongue, the current study found that this protein was not expressed specifically in taste bud cells by studying mice as a model organism.

In a conversation with Bloomberg, tech titan and philanthropist Bill Gates said that while vaccine development may be happening at a rapid pace, the first Covid-19 vaccine to be released may not be the best one.
Gates went on to explain that, 'the initial vaccine, in terms of its effectiveness against sickness and transmission, won&rsquo;t be ideal and may not have a long duration.'
The Microsoft founder, through this Bill and Melinda Gates Foundation,&nbsp;has pledged more than $250 million towards Covid-19 research and is also funding vaccine development by&nbsp;AstraZeneca PLC, Johnson &amp; Johnson and Novavax Inc.
As per Gates' statement to Bloomberg, 'innovation in diagnostics, therapeutics and vaccines will get us largely out of this by the end of 2021.'&nbsp;

US biotech company Moderna's vaccine candidate protected mice from infection with SARS-CoV-2 virus that causes COVID-19, according to a study published in the journal Nature on Wednesday.&nbsp;
The findings&nbsp;show that the vaccine, known as mRNA-1273, induced neutralising antibodies in mice when given as two intramuscular injections of a 1-microgramme (mcg) dose three weeks apart.&nbsp;Mice challenged seven weeks after only a single dose of 1 mcg&nbsp;were protected against viral replication in the lung, they said.&nbsp;The latest study found that the investigational vaccine also induced robust CD8 T-cell responses in mice.
The team noted that the data from these studies, combined with data from studies in nonhuman primates and Phase-1 clinical testing, support the evaluation of this vaccine in clinical efficacy trials.

The odds of contracting Covid-19 on a flight are slim but that doesn't mean it's absolutely safe to fly in the midst of a global pandemic!
According to Arnold Barnett, a&nbsp;professor of management science at the Massachusetts Institute of Technology,&nbsp;1 in 4300 passengers will pick up the virus, while on a 2-hour plane journey.
Barnett weighed in on several factors like protection of masks onboard&nbsp;may fail or the odds that you would be seated next to an infectious passenger.&nbsp;
He however feels that the discretion lies upon the individual as you need see the risk you could pose to others by contracting the virus.&nbsp;
The results of his study have not been peer reviewed as yet but he states that the odds of getting virus if airlines leave the middle seat empty, are about&nbsp;1/7700.
So experts believe, if you opt to fly, try booking tickets with airlines that leave the middle seat empty.&nbsp;

People are getting seriously sick and a few have died after swallowing hand sanitizer, the US Centers for Disease Control and Prevention said in a new report.
The CDC cautioned against use of hand sanitizer, urging people that it is not safe to swallow. The team described the case of 15 adults in Arizona and New Mexico admitted to hospitals for methanol poisoning from hand sanitizers between May and June.
Some of them even developed visual impairments and had seizures.However, it is not clear as to why people were consuming it.

Smoking weed is not good for the heart, a new scientific statement by the American Heart Association says.
According to the deputy chief science and medical officer for the AHA, smoking or vaping any product, including cannabis, may potentially harm the lungs, heart and blood vessels.
The new statement, based on existing research on the link between cannabis and heart, found that weed may interfere with existing prescribed medications and trigger cardiovascular events. Published in the AHA journal Circulation, a health professional&nbsp;must be consulted before using marijuana, it added. Only legal cannabis products must be used, if at all.
The existing data on the link between cannabis and the heart showcased problems like heart rythm abnormalities, chest pain and other serious conditions. It is even more harmful for those with already existing heart disease.
 While all these studies are short term and observational, there is an urgent need for more research, the association said.

A study from 2013 evaluating physical attractiveness of women with and without endometriosis&nbsp;has&nbsp;been retracted from the medical journal Fertility and Sterility after years of&nbsp;criticism. The research drew heavy backlash from doctors for ethical concerns and dubious justifications, reports The Guardian.
According to the peer-reviewed study's&nbsp;findings, "women with rectovaginal endometriosis were judged to be more attractive than those in the two control groups. Moreover, they had a leaner silhouette, larger breasts, and an earlier coitarche," the study concluded.&nbsp;
Rectovaginal endometriosis is a painful chronic condition in which&nbsp;endometrial&nbsp;tissue forms adhesions outside of the uterus.&nbsp;
Unsurprisingly, the study was described as 'disgusting' and 'shameful' by the medical community.
The journal has not issued an apology but published a letter co-signed by all the authors involved, that says: "We conducted the study in good faith and according to correct methodology...&nbsp;Women&rsquo;s respect is a priority for us, and we are extremely sorry for the discontent the publication originated."&nbsp;

The immune system's memory helper T cells which recognise the common cold virus and help the body fight it off, also identify some parts of the novel coronavirus, according to a study whose findings may explain why some people have milder Covid-19 cases than others.
The research, published in the journal Science, noted that the immune system's memory T cells keep track of the viruses they have seen before, giving the cells a headstart in recognising and fighting off repeat invaders.&nbsp;
'In some people, pre-existing T cell memory against common cold&nbsp;coronaviruses&nbsp;can cross-recognise SARS-CoV-2, down to the exact molecular structures," said Daniela Weiskopf, a co-author of the study from LJI.

Drug major Lupin on Wednesday announced the launch of its Favipiravir drug under the brand name 'Covihalt' for the treatment patients with mild to moderate Covid-19 symptoms at Rs 49 per tablet in India.
Favipiravir has received authorisation from the Drug Controller General of India (DCGI) for emergency use, Lupin said in a regulatory filing.
Its Covihalt dosage strength has been developed keeping in mind the convenience of administration, it stated.

The weighing scale should not be the sole measure for obesity, that's what a new&nbsp;Canadian clinical guideline notes. The guideline&nbsp;says obesity must not be solely defined by an person's weight but must also take into account a person&rsquo;s overall health.&nbsp;
According to the new guideline, which was published in the Canadian Medical Association Journal, doctors must go beyond diet and exercise and address weight gain at its roots, using a &lsquo;holistic&rsquo; approach.&nbsp;
While the new guideline makes use of measurements like waist circumference and Body Mass Index, it does recognise the limitations attached with these measures. It encourages doctors and medical professionals to offer support to &lsquo;obese&rsquo; individuals through therapy and medication.&nbsp;

The US Centers for Disease Control and Prevention has warned parents and doctors to be ware of a polio-like condition&nbsp;called acute flaccid myelitis, or AFM&nbsp;in children. The cases of this condition tend to peak in the United States every other year and experts believe this year could see an upsurge in cases.
However, due to the ongoing Covid-19 pandemic, things could get more complicated. Parents may not be able to recognise cases of AFM&nbsp;this time and there maybe hesitancy to visit a doctor due to the outbreak.&nbsp;
The most telling symptom of AFM&nbsp;is muscle weakness along with bouts of fever and respiratory illness.&nbsp;
The CDC&nbsp;has urged parents to take quick action to ensure better recovery, even in the midst of the pandemic.&nbsp;

Scientists have created a blood test that could detect if a newborn baby has been deprived of oxygen at birth, a condition which increases the risk of neuro disabilities like epilepsy and cerebral palsy.
The prototype blood test, developed by a team of researchers led by Imperial College London, is based on an early study of 45 babies who experienced birth asphyxia. Blood test of these babies was taken six hours after birth and a follow up was conducted after 18 months to see which of them had developed disabilities.
During the research, which was also conducted in hospitals in India, the scientists identified changes in 855 genes in babies, which could explain the neuro&nbsp;disabilities.
The blood test may help disrupt neurological disabilities, develop new therapeutic interventions and improve outcomes.. The babies were a part of a trial in low and middle income countries called Hypothermia for Encephalopathy. Further examination of the genes will be conducted to ascertain the findings.

New research studying&nbsp;anxiety and depression in Covid-19 survivors has found that more than half of hospitalised Covid-19&nbsp;patients suffered from a&nbsp;psychiatric disorder a month later.&nbsp;
Experts from San Raffaele hospital in Milan report that, based on clinical interviews and self-assessment questionnaires, 40% of patients said they developed insomnia,&nbsp;depression for 31%, anxiety for 42% and PTSD was reported by 28% of Covid-19 survivors.
The study of 265 men and 137 women published the journal Brain, Behavior and Immunity also found that female patients&nbsp;suffered more than males, scoring higher in all the measures. The team recommended&nbsp;more research on inflammatory biomarkers&nbsp;to diagnose and treat emergent psychiatric conditions.

Smokers are likely to be more vulnerable to the new coronavirus as smoking increases the possibility of transmission of the virus from hand to mouth, the Union Health Ministry has said. Use of tobacco products can increase the severity of respiratory infections and make people susceptible to Covid-19, the ministry warned in a new document.
In the report, experts&nbsp;confirm that smokers are more likely to develop severe symptoms or die from Covid-19, as it primarily attacks the lungs.
'Further smoking products such as water pipes or hookah often involve the sharing of mouth-pieces and hoses, which could facilitate the transmission of Covid-19 in communal and social settings,' the ministry said.

As the world rushes to reduce Covid-19's death rate, there is another ongoing&nbsp;crisis&nbsp;whose death toll is posed to be far greater and is going largely&nbsp;unrecognised. New research says that mortalities related to a global rise in temperatures will be much&nbsp;higher than deaths from all infectious diseases combined if&nbsp;planet-heating emissions aren&rsquo;t controlled.
If emissions are not curbed,&nbsp;global mortality rates will rise by 73 deaths per 100,000 people by the end of the century. The tally matches&nbsp;the current death toll from all infectious diseases, such&nbsp;as tuberculosis, HIV, malaria, and dengue.
Published by the National Bureau of Economic Research, the study found that much like the novel coronavirus, climate-related deaths will also make people with pre-existing conditions like heart or lung problems, more vulnerable to its impact.
The worst brunt of the crisis will be faced by poorer nations inhabiting some of the hottest regions on Earth including&nbsp;Ghana, Bangladesh, Pakistan and Sudan.
Studying a huge&nbsp;global dataset&nbsp;linking death with temperature records, the team found the economic cost of these deaths to be around 3.2% of global economic output by the end of the century if things don't change.&nbsp;

Spravato, a&nbsp;nasal spray by US pharma&nbsp;giant Johnson &amp; Johnson's has got the FDA&nbsp;approval, making it the&nbsp;first antidepressant spray that can be prescribed&nbsp;for actively suicidal people.&nbsp;
As the Covid-19 outbreak took a toll on the mental health of many across the globe, the nasal spray aims to offer a 'quick path to remission'.
Trials have shown that the spray reduces depressive symptoms within 24 hours, where as traditionally available oral anti-depressants could take weeks or even months to show effects.&nbsp;
Since its approval in March 2019, the spray has been used by approximately 6,000 people for what is known as treatment-resistant depression.&nbsp;
&nbsp;

A blood test to diagnose the Alzheimer's disease may soon be a possibility. An experimental blood test has yielded&nbsp;accurate results in differentiating people with dementia from those without it. Latest trial results showed 89% to 98% accuracy, but larger trials are still required to ascertain the findings. The results were discussed online at the Alzheimer's Association International Conference. Currently, the disease is diagnosed through tests of thinking skills and memory. Other tests like spinal fluid or brain scans&nbsp;are either expensive or invasive. This finding focuses on the protein called 'tau' and finds that one of its forms&nbsp;is a reliable indicator. The study was sponsored by US National Institutes of Health, Swedish government health groups, and the Alzheimer&rsquo;s Association among other companies and foundations.

Spain is all set to roll out a&nbsp;Covid-19 contact-tracing app in September, after a pilot project showed that it was capable of detecting twice as many potential infections as human tracers.
The pilot project was conducted on a tiny island near&nbsp;Tenerife&nbsp;in July, using a&nbsp;new system developed by Google and Apple and can detect contact with even strangers.
Participants entered a random code in the app, some of which falsely indicated a positive Covid-19 test and the app then alerted everyone who spent a minimum of 15 minutes at a proximity of 2 metres or less.&nbsp;
Several other nations are now looking to use similar harnessing technology to bolster the fight against the&nbsp;pandemic.

According to a new study by Public Health England, obesity increases the risk of getting severely unwell from Covid-19. The study found that excess weight put people at a greater risk of requiring hospital admission or maybe even intensive care. The report said that supporting people to achieve and then maintain healthy weight could help reduce severe effects of&nbsp;Covid-19 as well as other life threatening&nbsp;diseases. The review lists excess weight as a significant risk factor for&nbsp;Covid-19.&nbsp;

It's not just the lungs that get severely affected in coronavirus disease patients but also the heart. According to a new study, as many of 78% of Covid-19 patients monitored developed a heart condition
