The incubation period of COVID-19 patients has been increased, suggesting probable carriers to quarantine longer

Scientists have extended the incubation period for COVID-19 patients to 7.7 days. While earlier studies had established this period to be between 4 to 5 days, new analysis now shows that this was an understatement.

The impact of this miscalculation has been already witnessed in the form of a rampant infection spread throughout the world. There are 21.6 million confirmed COVID-19 cases worldwide, with the number of deaths rising slowly, despite of so many SOPS.

Due to being highly contagious and already showing signs of mutations, the novel COVID-19 virus has raised concerns among researchers. With so much uncertainty about the true attributes of the virus, the validity of these revised incubation periods remains undecided for the nearing future.

Why is the correct determination of incubation period important?

The correct determination of incubation periods is extremely important to understand the behavior of a virus or infection. It determines the length of quarantine periods and the necessary steps required to stop the infection transfer.

Shorter incubation periods for COVID-19 has led asymptomatic patients to believe they were clear of the infection. Since their typical symptoms took longer to appear than the established limit of 4 to 5 days, the patients who quit quarantine were spreading the virus without realizing it.

With the new incubation period of 7.7 days, chances of containing the virus is increased by a good margin. It is highly likely for a majority of patients to experience the symptoms by the end of this period. This will allow necessary measures to be put into effect as soon as possible.

Why was the incubation period downplayed in earlier studies?

According to scientists, the earlier underestimation of incubation periods was affected by various factors.

The initial sample sizes that were selected for research were much smaller. Most data was based on self-reports which could have been impacted by memory gaps or any misjudgment by both the patient and the researcher.

All of these factors led to an undermining of results, leading to consequential damages.

New researches on COVID-19 incubation period

Considering the above mentioned limiting factors, a new research conducted by concerned bodies had a much better accuracy due to the use of various techniques.

Results were calculated using a much larger sample, comprising of about 1084 people in Wuhan, China. Researchers in China used renewal theory to deduce results from their data. This technique allowed them to remove recall bias, eliminating all problems associated with recalling an incident from the data.

A number of variables were used to collect the data. These included travel history, residence of subjects, date of diagnosis, date of onset of symptoms, and the number of confirmed cases around the area of study i.e Wuhan.

This data was obtained from databases of health commissions in China and health ministries of other countries.

The conclusive findings of the research pointed that the average incubation period in a majority of patients was 7.7 days. A small percentage of the research population also showed incubation periods over this limit of 7.7 days, with some showing symptoms at 14.28 days.

Who should consider incubation?

With so much variability in the appearance of symptoms, most people wonder whether or not they should consider quarantining.

For the most part, quarantine is necessary for people who have traveled using mass transit or gotten exposed to an infected person.

Exposure is possible when contact is made with an infected person for fifteen minutes or more within a distance of six feet. In other cases, physical exposure to the respiratory droplets of the patient can cause an infection. Reports of cases where contact was made during patient care have also been seen, increasing the different scenarios where exposure is possible.

If anyone is faced with any of these situations, quarantine should be seriously considered. With incubation periods varying so much between individuals, experts recommend quarantining for at least 14 days.

Detailed information regarding of quarantine cycles can be obtained from the CDC website.

An understated incubation period can be widely blamed for the uncontrolled spread of COVID-19. With this, the importance of quarantining is evident.

Study Shows No Significant Mental Effects In Elderly Patients Using Medicinal Cannabis For Chronic Pains

Published

Cannabis for chronic pain doesn't impair brain

The elderly, often subjected to various medical conditions, need therapies and treatments as much as any other age group. Yet unfortunately, some point out that the field sometimes doesn’t get as much attention as younger groups. That may explain why pediatric doctors greatly outnumber geriatric specialists. And then, there does exist the tendency for the elderly to be more likely to be dismissed, compared to younger patients. Regardless, one of the most common aliments in the elderly is that of chronic pain in different parts of their aged bodies. Luckily, medicinal cannabis may hold the solution for them, as numerous experts find its properties useful for old people.

A recent study from Israel set out to ascertain whether or not weed would harmfully affect the cognitions of a sample of aged individuals. The participants included both middle-aged individuals and the elderly ones, as both seemed likely to have chronic pains. Furthermore, because the aim was to find effects on cognition, both types had fully-developed brains. What the scientists found may further the needle for the campaign to normalize medicinal cannabis.

The study set up strict controls and parameters to keep it as accurate as possible

The problem that arises with any diverse sample is the presence of individual differences. If not adjusted for, these can lead to a skewed data set and make the results questionable. In this case, the researchers strove to ensure all participants were as similar as possible. They were all above the age of 50, and no significant history with alcohol abuse or hard drugs. Some of the participants were on medicinal weed licenses, meaning they actively used it regularly. Others used it very sporadically. However, all abstained from cannabis use at least 3 hours prior. They also had similar education levels and all medically recognized as mentally sound.

The study included exactly 63 licensed individuals with the remaining 62 unlicensed. The male to female ratio was also about half and half, so sex didn’t affect the results. This almost even split served to better reproduce a normal distribution with acceptable standard deviations. Furthermore, they used a reliable software called ‘CogState’, which comprises of computerized cognitive exams. These exams covered everything required, from memory to attention spans.

The results indicated that regular cannabis use to treat chronic pains left no significant impact on cognition in the elderly

By all standards of scientific research methodology, the study mainly came out as a success. The results showed the initial hypothesis proved correct, and cannabis caused no major mental changes. In practically all participants, cognition was on par with normal levels and the frequent cannabis users did not vary much from rare users. Hence, the paper claimed that treating chronic pains with CBD (cannabidiol) and THC (tetrahydrocannabinol) would leave no lasting mental effects.

However, one interesting and alarming finding the study showed was an elevated risk of cardiovascular disease from cannabis. In addition, regular users also showed elevated frequencies of depression. The former of these may occur due to smoking cannabis rather than eating it. However, it does corroborate what a recent American Heart Association (AHA) paper claims.

While the study did have some limitations, it still shows important findings for those on the fence about medicinal weed

No truly scientific study can claim to have zero room for improvement. While they accounted for most extraneous factors, the biggest factor was the cross-sectional aspect. This means that due to broad generalizations about samples, the study cannot definitively establish cause and effect. Also, they didn’t account for previous medicinal histories.

However, the study still puts to rest many fears about brain damage from weed. For more on medicinal cannabis, stay tuned!

The Unsettled Science On The Effect of Cannabis On COVID-19

Published

on

COVID-19 and cannabis usage leaves mixed data

Cannabis certainly made its mark upon the medical world within the past few decades. Historically shunned, and dismissed as a cheap drug, weed now bears its own therapeutic prowess. Researchers, healthcare experts and experienced users alike all testify to its claimed health benefits and properties. Even when it comes to the terrible COVID-19 pandemic, cannabis gets talked about and undergoes consideration fairly frequently.

However, scientists admit the matter of just how useful cannabis is for use in COVID-19 patients stumps them. Unlike the concept of gravity or climate change, there exists no consensus. Some argue the drug holds several positive health effects, while others that it may worsen symptoms. So, all in all, cannabis still comprises of widely-polarizing evidence that only serves to increase mistrust in it.

Recent studies highlight marked benefits to cannabis when used to treat COVID-19

One of the most exciting, and high-profile, studies that showcase cannabis’s therapeutic potential is this Israeli one. Eybna and CannaSoul, two collaborating cannabis companies, recently launched a joint study into cannabis terpenes and coronavirus. Terpenes, small molecules of organic nature naturally present in the cannabis plant, create the distinct scent of weed. This study found that terpenes proved an effective treatment for COVID-19 patients with ‘cytokine storm’.

Cytokine storm refers to a serious feared complication seen in some younger patients infected with COVID-19. Normally, the body releases cytokines as mediators of immune response. Thus, moderate levels of cytokines play a vital role in immunity. However, in some patients the immune system flares up so severely that excess cytokines release into the blood. This phenomenon leads to inflammation, fever, gastrointestinal disturbances, respiratory issues and even death. Hence, the study’s findings proved game-changing, and even seemed more effective than dexamethasone.

However, evidence also shows cannabis intake may severely hinder essential immune responses

Despite the previous study, scientists also investigate the side-effects of cannabis use and links to COVID-19. They found recently that cannabis may hinder immune responses even in uninfected patients. This is best explained by the way weed works on the body’s endocannabinoid system, which regulates sleep, immunity and other functions. Because combating infections requires an initial surge in immune response, cannabis users may make themselves more open to coronavirus infections.

Furthermore, a recent study that called into question cannabis’s negative effects in immunotherapy patients. To treat certain cancers, immunotherapy seeks to destroy cancerous cells. And ideally, the body’s innate immune cells should take as little damage as possible. Unfortunately, given marijuana’s tendency to reduce immunity, users on immunotherapy get weakened results. Hence, researchers now suggest users with suspected COVID-19 symptoms hold off on the pot.

Despite mixed results with treating COVID-19, medicinal cannabis still holds a wide array of therapeutic benefits

Let’s face it, cannabis still doesn’t get the attention and respect it deserves. In the medical field, however, it gets harder to ignore weed’s influence and popularity. Dentists and surgeons now use it for post-operation recoveries due to its painkilling effects. Its ability to smooth out brain waves makes it ideal for juvenile seizure patients. And lastly, what better drug to ease anxiety and depression patients?

So therefore, it seems a minor side effect of COVID-19 may leave users unsafe. As experts recommend, abstaining just until the COVID-19 vaccine comes out might prove safe. In the meantime, let’s hope more and more healthcare providers turn to prescribing cannabis where appropriate.

Patients Prescribed Cannabis In Georgia, USA, Can’t Legally Obtain It

Published

Georgia cannabis patients can't get theirs

The United States of America often astounds the rest of the world with just how ludicrous its laws seem. Take the example of recreational cannabis, which remains federally illegal since decades. However, a few select states, such as California, Colorado and Georgia, allow small quantities of legally purchased cannabis. Everywhere else, possession of cannabis remains a misdemeanor offense, and other disproportionately severe punitive measures.

In Georgia, in particular, the case of medicinal marijuana recently emerged as troubling. For many patients, medicinal weed simply is a lifesaver and experts agree that it packs unique therapeutic effects. However, in the state of Georgia in particular, it seems like a cruel joke that obtaining said weed becomes near impossible. And this is despite the fact that it’s been legal to possess since 2015.

Despite the usage of medicinal cannabis being legal in the state of Georgia, purchase or sale remains illegal

As far as ridiculous laws go, this one stands out as extremely cruel. With doctors able to prescribe doses of cannabis to ailing patients, the lack of any places to legally obtain it seems absurd. And no, buying cannabis from a shady back alley dealer is not a safe idea. Not just because of the chance of getting caught but because there’s no guarantee the product is what you pay for. Only a legal and regulated avenue available would help.

In 2019, at the behest of several concerned citizens, official government action started. The state governor set up the Georgia Access to Medical Cannabis Commission in 2019 to discuss this terrible issue. And yet, the problem still stands. This is because the panel only convened once, before the COVID-19 pandemic put the matter on hold indefinitely. Thus, millions of patients needing their drug have no one else to ask for help from.

For many patients with a variety of ailments, medicinal marijuana works wonders for their health

Medical science generally holds several consensuses on the health effects of different substances. No respectable doctor will ever claim that arsenic is good for your health. And when it comes to cannabis, the leading consensus after extensive studies and research holds opinions that cannabis may hold several cures. Weed, which consists primarily of CBD (cannabidiol) and THC (tetrahydrocannabinol), exerts effects on the body’s physiology. This leads to improvements in breathing, blood circulation, mood, and pain relief.

Various types of disorders that lead to seizures, such as West Syndrome, in all age groups exist. Fortunately, cannabis is also a known therapeutic agent for reducing the intensity of seizures. In many young individuals, such as a recent UK toddler, it offers marked improvements to health. Furthermore, cannabis offers health benefits to patients with PTSD, anxiety, extreme pain and even in certain cancers. However, there also exists evidence that in the smoked form, it can lead to cardiovascular issues in the long term. Hence, edibles or inhalables suit most users better, and offer better efficacy of the weed.

The United States sorely needs to fix its haphazard and primitive legislation regarding both recreational and medicinal cannabis use

Several conservative states, like Texas, where the most anti-cannabis attitudes prevail, reflect that in their legislation. From introducing ridiculous hemp regulation laws, to launching an entire War On Drugs, they’ve done it all. None of that changes the fact that cannabis stays, and will always do so.

The time comes now that lawmakers, urged by the people, reexamine the science. And then, hopefully change laws for the better. That remains to be seen, however.
