There are two theories that are quite similar in nature, but different in substance, The theory of Mind and the theory of Mentaliz(S)ation, sorry, Im allergic to American spelling...pls dont kill me now :-) My understanding of them is this "Both of these concepts, mentalization and the theory of mind, describes processes that are metacognitive in their nature . Mentalization mainly concerns the reflection of affective or emotional mental states. In contrast however the, theory of mind focuses on things epistemic in nature such as beliefs, intentions and persuasions. My idea is that these two theories by them self are incomplete but combining elements of both, gives us a clearer understanding. Cognition and affect can't in my view be separated, they are both part of us as human beings and also a part of other animals. What are your thoughts? Am I wrong or right? I can stand criticism so bring it on...

Dear Arvidsson & readers,
You wrote:
Cognition and affect can't in my view be separated, they are both part of us as human beings and also a part of other animals. What are your thoughts? Am I wrong or right?
---End quotation
"Cognition and affect," you say, "can't … be separated." Well, of course, in the sense that "they are both part of us as human beings," we can't separate them in the sense of eliminating one or the other. We don't want to eliminate either.
But in conceptualization of the distinction, we do separate them. We are aware, for instance that "hot cognition" tends toward more impulsive turns and acts, while cooler, more dispassionate discourse, debate or discussion depend on self-restraint on the immediate flow of emotion. In consequence it can be taxing or frustrating to the initiates. But this kind of self-restraint is widely viewed as an intellectual, even a moral virtue --a cultivate ability and eventual disposition. It seems that both in theory and in practice, we do "separate" cognition and affect and consider them distinct. So, let that much be recognized and accepted.
On the other hand, it is clear that if we did not care about anything in the sense that no matter what happened we would have no emotional reaction, then we would have little motivation (little reason, one might say) to engage in complex cognition, debate, discussion or discourse. What this tells us is that cognition also has its underlying emotional tone and basis, which, in fact, is reflected in personal ideals dating from ancient times: the desirability of "tranquility," or say, "eudemon," Greek, and literally to be of "good spirit," and conventionally translated as "happiness."
Classically, I think it is clearly recognized that there are varieties of developed character among human beings which are strongly rational and discursive and yet quite passionate in devotion to ideas and ideals.

What are different coil shapes used in Transcranial Magnetic Stimulation? What are their differences (in induced current)? Do they have different applications?
Relevant answer
Answer
Dear Nezad,
Actually, among standard commercial coils, the double cone coil offers high energy efficiency and balance between stimulated volume and superficial field strength. Direct TMS of targets at depths of approx 4 cm or more results in superficial stimulation strength that exceeds the upper limit in current rTMS safety guidelines. Approaching depths of approx 6 cm is almost certainly unsafe considering the excessive superficial stimulation strength and activated brain volume. Couple of effects might have seen with choice of shape/size/dimension/ material listed below.
Effect of coil shape/size
(1) ****Smaller coils have a focality advantage over larger coils; however, this advantage diminishes with increasing target depth. Smaller coils have the disadvantage of producing stronger field in the superficial cortex and requiring more energy.
(2) When the coil dimensions are large relative to the head size, the electric field decay in depth becomes linear, indicating that, at best, the electric field attenuation is directly proportional to the depth of the target.
(3) Ferromagnetic cores improve electrical efficiency for targeting superficial brain areas; however magnetic saturation reduces the effectiveness of the core for deeper targets, especially for highly focal coils. Distancing winding segments from the head, as in the H1 coil, increases the required stimulation energy.

Hello Colleagues
Recentrly, fungal infections cause an increase of morbidity and mortality in hospitalized patients and in immunocompromised persons. What are the most recent recommendations and guidelines for the control and prevention of nosocomial fungal infections.
Thanks
Relevant answer
Answer
The last two decades have shown an increase incidence of nosocomial fungal infections in hospital environment.The important fungi that are implicated in nosocomial infections are Candida albicans, Non-Candida albicans, Aspergillus fumigatus and Non-Aspergillus fumigatus, Fusarium species and others. We have isolated several fungal pathogens from burn wounds of patients admitted in burn ward of the hospital. Certain measures, such as personal protective wear, proper hand hygiene, respiratory hygiene, thorough cleaning and disinfection, safe injection practice, avoidance of sharp needle and scalpel injury, and waste disposal besides prompt medical attention to skin injury, and appropriate treatment with anti-fungal drugs (fluconazole, itraconazole, Amphotericin B, posaconazole etc) can be effective to prevent nosocomial mycoses.

Dear Scholars,
You all are well aware that COVID-19 has disrupted every aspect of our lives including K12 and higher education sectors. Keeping in view the WHO recommendations, nations are enforcing social distancing in all fields including primary, secondary, higher secondary and university education. If we think positively, then this culprit COVID-19 is a blessing in disguise as the people are now taking care of personal hygiene, cleanliness of their surroundings and trying their best to improve their immunity. Besides educational institutions are reaching to the students.
During the past three months, the schools and universities around the globe have extended their outreach from a confined classroom to the students` bedrooms. Now the students can learn with more flexibility without wasting their times in travelling to their respective schools. The online mode of education has proven fruitful as it has lead to reduce institutional expenses which they had been spending on building & maintenance of infrastructure, electricity, furniture, multimedia and computing equipment. There is likelihood that tuition fee may be reduced with time if the situation prolongs (god forbid).
Apart from the above facts, I personally believe that online mode of education can not replace laboratory and clinical training of students who are pursuing their undergraduate studies in medicine, dentistry, engineering and such other technical fields.
What do you think? Will this batch of undergraduate students who are learning through online media i.e. LMS, Zoom, Webax etc, be able to acquire the professional competencies required in their respective fields. If the answer is no, then how can we utilize online platforms to ensure delivery of the quality education and achievement of course and program learning outcomes?

  • patient eligibility
  • collection of COVID-19 convalescent plasma, including donor eligibility and donor qualifications
  • labeling, and

Answer
I write from the very beginning (;-/)... It is necessary to write a work plan and gradually insert finished pieces or its fragments into it. Then see what necessary parts are missing and add these. Everything is simple. After several passes, the skeleton (plan) is overgrown with meat (text). Sometimes I enter some thought (just a line or phrase) or data into this raw text as these arise in head. Sometimes in the process of work it turns out that the original plan was not very good, then new (first empty) paragraphs are added to the text, and something disappears. Gradually, the article arises. The most important thing is to reread it, it is better to pause before the last viewing (several days or even weeks) in order to be able to look at the text with a “fresh look”. This is not the only way. I know a person who writes linearly - from beginning to end, as a silkworm draws a thread from itself. But I can’t do this - it’s easier for me to construct text from logical "cubes".

Emergence phenomena is a kind of phenomena observed in a lot kind of systems (from arts to philosophy, biology, physics and so on). Emergence theory is the formal approach to study those phenomena. It is a very exiting area!
Actually, as you probably know, there are different levels of emergence. You may have weak emergence, strong emergence or even some intermediary relations. The kind of emergence phenomena you are considering are of weak type, which are typically related with complex systems (as maybe you were keeping in mind when you said (...) understand the dynamics of organizations' emergent properties that are virtually impossible to resolve by using any other mathematical tool (...).
I note, however, that a system A which weak emerge from a system B can a priori strongly emerges from a system C which itself strongly emerges from B (there is no contradiction because the emergence relation is not transitive in the general setup). This means that one can try to understand weak emergence relations (and therefore those complex systems) indirectly by looking at strong emerge relations.
With this in our minds, a natural question is the following:
  • existence problem for strong emergence. Given two systems A and B, can we find some strong emergence relation between them?
At present I'm very interested in studying this problem for physical systems, but a priori the methods could be generalized to other kind of systems. I've a recent work on the subject:

In the age of Covid19, is there a basic conflict between science and superstition in the discipline of medical knowledge? Are there some simple, sensible, robust and reasonable ways to distinguish a scientific statement (or fact) from a superstitious statement?
To stay focused, the topic will concentrate on science versus superstition in the scientific discipline of medicine. We will try our very best to stay focused and not stray off track. it is very easy to wander off message and be all over the map. i will try to summarize the key conclusions from time to time.
In the age of the Corona Virus, there are so many statements out there. The statements may not be scientific. But if they are not scientific, are they false? Are they fake? Are they simply statements based on superstition.
What should we do if people believe in statements that are not based on science? Should we be polite and tolerate their beliefs?
As long as people do not harm others, then from society’s point of view, the fact that people hold non-scientific hypotheses is probably benign. However, the trouble starts when the same people act these beliefs, and then cause harm to others. The question arises: what should society do in this case?
Based on the discussion, there are two assumptions and four categories.
Assumption1: Beliefs cannot be justified or unjustified.
Assumption2: hypotheses can be disproven
Scientific hypotheses that are based on justified facts in natural causation. Or scientific hypotheses have not been disproven (I prefer the negative formulation because we may never be able to prove anything but we are unable to disprove it.)
Since science cannot give a definitive answer, there are many competing answers that merit our attention, and we may not be able to select among them.
Non-scientific hypotheses are unjustified facts that may be “proven” in the future with better evidence and facts.
Pseudo-scientific hypotheses: not sure where these fit in?
Superstitions are unjustified beliefs in supernatural causation.
Relevant answer
Answer
Joseph Tham, thanks for a thought provoking question. I think we should tolerate and respect beliefs and ideas that are not considered scientific. Our intolerance of such beliefs and ideas could be the result of a lack of understanding of the science behind them. We should therefore subject them to rigorous testing using the scientific method. A practical example is the fact that the World Health Organization has not dismissed out of hand the herbal remedy from Madagascar that is claimed to prevent illness from COVID-19. Instead the remedy is going to be tested using established scientific principles. The null hypothesis can then be rejected or accepted. This is how Indigenous Knowledge Systems contribute to scientific advancement.

Different specialties have different practicing needs, what difficulties do you encounter on applying tele-medicine under COVID-19 in your specialty? Will tele-medicine totally uproot the usual face-to-face room consultation of medical practitioners? And becoming the new service model?
What is your view?

Hello, in Portugal, during Covid there was a huge increase of tele consultation. Still some barriers were found:
- older people have more difficulties in using digital tools.
- 3G and 4G coverage is still low in some rural areas.
- Lack of good tele consultation tools available to be used, some physicians then still want to do the face to face consultation.

Answer
Metal corpus of the ship (moisture, condensation, mold, lower temperature). Creates confined space.
Cold air currents when the ship is moving. Some cabins have a terrace. Other passangers use the common outside viewing decks.
Vibrations from the ship's engine disturb, days on end, the normal liquid environment (intracellular, extracellular) within which cells live, function, reproduce. The vestibular apparatus suffers as well.
Cleanliness - dubious. Could use the toilet brush to clean also the toilet seat and the sink with (as in many hotels around the world). Apparently, nothing wrong with that. :O
Lack of adequate ventilation (probably, the air conditioning system is linked between rooms at the same level).
Fresh water purity (absent - onboard water desalination; when were the filters last changed?).
Bacteria and viruses jump from sea water onto skin, in nose and throat via water droplets in the air. When humid, one inhales deeper. Boy, is this not helpful!
Toilets and shower waste water outlets connected - water pressure differential due to movement of the ship (esp. side to side). Splashes in the bathroom.

Treatment and management of cholera are best accomplished by the administration of copious amounts of intravenous or oral fluids to replace fluids lost from the severe diarrhea. The administration of antimicrobial agent can be shorten the duration of diarrhea and thereby reduce fluid losses. However, resistance to tetracycline and doxycycline has been reported. Therefore administration of additional antimicrobials such as azithromycin and ciprofloxacin may be necessary.

Developing a vaccine is an important task. What is the best way to achieve this goal? Should we use a global competitive process?
Relevant answer
Answer
Less than five months after the world first learnt about the new coronavirus causing fatal pneumonia in Wuhan, China, there are more than 90 vaccines for the virus at various stages of development, with more announced each week. At least six are already being tested for safety in people.
Now, developers, funders and other stakeholders are laying the groundwork for their biggest challenge yet: determining which vaccines actually work.
This typically involves giving thousands or tens of thousands of people a vaccine or placebo and seeing, over months or even years, whether there is a difference between the two groups in how many people get infected in the course of their daily lives, as well as checking that no safety issues emerge.
But in this pandemic, scientists will have to accelerate and streamline that process. A vaccine may be the only way to generate immunity to the virus across a population: despite the millions of coronavirus cases worldwide, some preliminary studies suggest that only a small fraction of people in even hard-hit regions have been infected with SARS-CoV-2, and their immunity is unclear.
This month, the World Health Organization (WHO) in Geneva, Switzerland, sketched out plans for a clinical trial that will test numerous vaccines in a single study. Some developers and funders have plans for their own efficacy trials. But key questions remain, such as which vaccines will be tested first — or at all — and how their effectiveness will be measured and compared.
“It’s going to require a level of coordination that has never really happened before, and a time frame that’s never really been even imagined,” says Mark Feinberg, president and chief executive of the International AIDS Vaccine Initiative (IAVI) in New York City. “You can’t take 200 vaccines into efficacy trials,” says Seth Berkley, chief executive of Gavi, the Vaccine Alliance in Geneva, which funds immunizations in low and middle-income countries.
Rolling trial
The WHO’s proposed Solidarity Vaccine Trial seeks to speed development with an adaptive design. This allows vaccines to be added to the trial on an ongoing basis. Participants will be enrolled continuously, and vaccines that don’t seem to be working can be dropped from testing.
The WHO still needs to hammer out details, such as how a vaccine’s efficacy will be measured, says Marie-Paule Kieny, research director at the French National Institute of Health and Medical Research in Paris. But she thinks its overall approach makes sense. “One of the challenges is prioritization — which vaccine should you test first,” she says.
The WHO has established an expert panel to prioritize vaccines for inclusion in its trial, but it is unlikely to be the only organization seeking to do this. “Some strategic alignment and coordination in this effort is going to be critically important or otherwise it'll become very chaotic,” says Feinberg. But the WHO plan “by itself may not be sufficient,” he adds.
The US National Institutes of Health (NIH) in Bethesda, Maryland, this month unveiled a partnership with more than a dozen companies that aims to coordinate the development of drugs and vaccines for coronavirus. And the Coalition of Epidemic Preparedness (CEPI), a global foundation that funds vaccine development, is supporting 9 different vaccines. The non-profit hopes to raise US$2 billion to pay for efficacy trials, manufacturing and other costs, says Melanie Saville, the organization’s director of vaccine research and development.
Criteria for prioritizing vaccines for efficacy could include its production capacity and the immune response generated in early human trials and animal studies, says Kieny, as well as regulators’ experience with the specific type of vaccine. Some of the kinds of vaccine being developed, such as RNA vaccines, have not been widely tested in people or used in a vaccine that has won regulatory approval.
A vaccine developed at the Jenner Institute at the University of Oxford, UK, is currently undergoing early-phase trials. “There’s a reasonable chance that we’ll be able to pick up the efficacy of the vaccine over the next couple of months,” Andrew Pollard, an infectious disease researcher at Oxford leading the trial, said at an online press briefing.
A small number of developers with plans and funding to get their vaccine approved and scale up production will likely call the shots with regard to how efficacy trials are done, says Rip Ballou, a program leader at IAVI. “Doing a phase III trial to show efficacy is meaningless if it's not coupled to a plan to actually licence and deliver under some regulatory authority,” he says. “There's only a handful of players that will be able to meet that very high bar. Because otherwise, it's a publication. It's not a vaccine.”
A fair shot
Another challenge will be determining how the different vaccines compare to one another. WHO’s proposal for an efficacy trial could allow the performance of different vaccines to be directly compared, but Kieny thinks that some developers may be unwilling to accept this because it could hurt a vaccine’s commercial prospects.
Swati Gupta, IAVI’s Vice President and Head of Emerging Infectious Diseases and Scientific Strategy, says vaccine developers will want to understand how key decisions are made before committing to trials that involve comparisons with other vaccines, to make sure their vaccines have “a fair shot at being able to show its efficacy”.
But it is essential to be able to compare different vaccines, even if it requires vaccines developers to set aside their short-term interests, says Charlie Weller, vaccine lead at the Wellcome Trust biomedical charity in London. “They work under commercial business models. That's not going to work for the situation we're in now," she says.
Expected global demand for a coronavirus vaccine could make developers more willing to cooperate. “We need more than one vaccine,” says Kieney. “Monopoly is always very bad, and none of the vaccines may have enough production capacity.”
One factor that could encourage such cooperation is the shifting geography of the pandemic. “China would have been a great place in Wuhan to have done efficacy trials two months ago,” says Berkley. “Italy would have would have been a great place to do it a month ago.” As a result, developers have incentive to join initiatives such as the WHO’s or the NIH’s, because of their access to clinical trial infrastructure around the world that could bring vaccines to where there are coronavirus cases. “We need to be nimble,” adds Gupta.
Emergency use
While most experts see large trials as a necessity to ensure that coronavirus vaccines are safe and effective, some developers are examining alternatives.
One option is to look for signs that a vaccine works in early-stage trials involving hundreds of participants, and then seek permission from regulators to deploy the vaccine under ‘emergency use’ rules in high-risk groups, such as health-care workers, who are more likely to be infected with the coronavirus. Regulators such as the US Food and Drug Administration can grant emergency use, while additional data is collected to license a vaccine.
Cansino Biologics in Tianjin, China, which is developing a vaccine comprised of a chemically inactivated form of SARS-CoV-2 virus, will consider this approach, according to a company spokesman. Johnson and Johnson said in a press release that its vaccine could be ready for emergency use in early 2021.
No vaccine has ever been deployed under emergency-use provisions, says Katherine O'Brien, who heads WHO's immunizations, vaccines, and biologicals department. If coronavirus vaccines follow that path, regulators will seek extra reassurance that a vaccine is safe. “There is no compromise that can be made on the safety issues,” O’Brien adds.
Momentum is building for an even more radical proposal to determine which vaccines work: intentionally infecting young, healthy volunteers, negating the need to wait for trial participants to become infected naturally. These ‘human challenge’ studies are already used to study infectious diseases such as malaria and dengue, and some researchers say they should be considered to speed the development of coronavirus vaccines.
Berkley says challenge trials could be used to rapidly determine which vaccines advance to large-scale trials. But he thinks they may be too risky without either an effective drug or a genetic test to identify the rare young individuals who are likely to develop severe disease. “Until you have a recognised treatment, I think that's a pretty tough story,” he says.

The virus is primarily spread between people during close contact, often via small droplets produced by coughing, sneezing, or talking. While these droplets are produced when breathing out, they usually fall to the ground or onto surfaces rather than remain in the air over long distances.People may also become infected by touching a contaminated surface and then touching their eyes, nose, or mouth. The virus can survive on surfaces for up to 72 hours. It is most contagious during the first three days after the onset of symptoms, although spread may be possible before symptoms appear and in later stages of the disease.

Dear Dr. Ebada,
We know very little about COVID-19 at this moment and its effects on the developing and/or mature brain. In general viral infections can impair charnolophagy (CB autophagy) which is the basic molecular mechanism of intra-cellular detoxification (ICD) for normal function to remain healthy. By attacking the most sensitive neural progenitor cells in the brain, the virus can alter their pluripotency and induce charnolosome (CS) destabilization implicated in inflammasome (particularly NRLP-3) activation to induce hypercytokinemia and charnoptosis (CB apoptosis) implicated in pyroptosis, apoptosis, and necrosis of sensitive hippocampal and other CNS neurons by releasing Panx-1, Viroporine, and gasdermins to cause Charnoly Body Molecular Pathogenesis (CBMP) implicated in early morbidity and mortality through its general (Viral) lytic cycle.
For more details, you may please refer to my books " The Zika Virus Disease: Prevention and Cure" The Charnoly Body: A Novel Biomarker of Mitochondrial Bioenergetics" Fetal Alcohol Spectrum Disorder; and Nicotinism and Emerging Role of E-Cigarettes. I wish I could write more about it.
Dr. Ebada, It is all about Environmental Sanitation, our own Life-Style, Immunity, Mitochondrial Bio-energetics and intracellular detoxification through charnolophagy (CB autophagy), which is compromised by COVID-19 through CS destabilization to cause early morbidity and mortality by infecting the CNS.

COVID- 19
Respiratory infections can be transmitted through droplets of different sizes: when the droplet particles are >5-10 μm in diameter they are referred to as respiratory droplets, and when then are <5μm in diameter, they are referred to as droplet nuclei. According to current evidence, COVID-19 virus is primarily transmitted between people through respiratory droplets and contact routes.2-7 In an analysis of 75,465 COVID-19 cases in China, airborne transmission was not reported.
Droplet transmission occurs when a person is in in close contact (within 1 m) with someone who has respiratory symptoms (e.g., coughing or sneezing) and is therefore at risk of having his/her mucosae (mouth and nose) or conjunctiva (eyes) exposed to potentially infective respiratory droplets. Transmission may also occur through fomites in the immediate environment around the infected person. Therefore, transmission of the COVID-19 virus can occur by direct contact with infected people and indirect contact with surfaces in the immediate environment or with objects used on the infected person (e.g., stethoscope or thermometer). 
Airborne transmission is different from droplet transmission as it refers to the presence of microbes within droplet nuclei, which are generally considered to be particles <5μm in diameter, can remain in the air for long periods of time and be transmitted to others over distances greater than 1 m. 
In the context of COVID-19, airborne transmission may be possible in specific circumstances and settings in which procedures or support treatments that generate aerosols are performed; i.e., endotracheal intubation, bronchoscopy, open suctioning, administration of nebulized treatment, manual ventilation before intubation, turning the patient to the prone position, disconnecting the patient from the ventilator, non-invasive positive-pressure ventilation, tracheostomy, and cardiopulmonary resuscitation. 
There is some evidence that COVID-19 infection may lead to intestinal infection and be present in faeces. However, to date only one study has cultured the COVID-19 virus from a single stool specimen.  There have been no reports of faecal−oral transmission of the COVID-19 virus to date.

Are immunity enhancer medicine (Homeopathic and Ayurvedic ) helpful to prevent yourself from Corona virus?
Relevant answer
Answer
Yes, an immune enhancer medicine naturally produced from plant combinations (herb
- to- herb) may likely prevent corona virus disease. This is because plants contain micronutrients and antioxidants that helps to boost the immune system and prevent the oxidation of free radicals in the body. COVID-19 is a
respiratory tract infectious disease (RTIs) caused by virus. Most medicinal plants have anti microbial and antivirus activity.

Hello!
I would like to understand in what cases blood or some other biological liquid passes through implant or graft with some porous microstructure according the Darcy law (thanks to the pressure differences).
I have an idea to produce a research about blood permeability through various implants microstructure, but unfortunately it is harder than I thought to found some justification in literature that blood actually could pass through such microstructure due the Darcy law. Thus, I would be grateful for your help in this question - maybe you have some papers about it or some other helpful stuff.

In a paper deposited in BioRxiv entitled: "Susceptibility of ferrets, cats, dogs, and different domestic animals to SARS-coronavirus-2" the team from Harbin Vet Institute intentionally infected several species of animals including cats with SARS-CoV-2. The results showed that the virus was transmitted between the cats, but no sympthoms of COVID-19 were observed.
This result is interesting in terms of an observation made by a medic from Spain - Sabina Olex-Condor that from the 100 patients serious with COVID-19 that she examined there were no cat owners. She suggested as a hypothesis that due to cross-immunity (cats are a known reservoir of coronaviruses) cat owners have milder sympthoms of COVID-19.
I'm aware that the paper from Harbin Institute is a pilot study, has many possible dead ends and limitations. I'm also aware that this cross-immunity hypothesis suggested by Sabina need serious assement due to limited number (and problalbly non-representative set) of patients.
Do you think that this is possible in terms of knowledge of human immunology? If the above is met do any of you have access to indepth demografic (?) data of people infected with SARS-CoV-2 to check this hypothesis?
Disclaimer: not an expert in medicine or veterinary, I study plant genomics, this is pure scientific curiosity.

There are thousands of coronaviruses infecting mammals. Humans commonly are infected with four which cause common colds (229E, OC43, HKU1 and NL63) and we have also been infected by SARS-CoV (2003-2004 outbreak) and MERS-CoV (2013 and other small outbreaks), as well as this new (SARS-CoV-2 pandemic) strain. Cats and dogs, and bats and pigs and cattle and horses all have coronaviruses of various types infecting them too.
There is no evidence that other cat coronaviruses such as the Feline coronavirus UU21, or Feline infectious peritonitis virus, can infect humans or cause any cross-protection against SARS-CoV-2. These viruses are all very distantly related to each other, and so are the 4 human common cold coronavirses, so we would not expect any cross-protection at all. If that type of broadly cross-protective immunity was possible, then one human influenza vaccine would be good for all, and making a vaccine for HIV would be easy.

When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or virions, consisting of: (i) the genetic material, i.e. long molecules of DNA or RNA that encode the structure of the proteins by which the virus acts; (ii) a protein coat, the capsid, which surrounds and protects the genetic material; and in some cases (iii) an outside envelope of lipids. The shapes of these virus particles range from simple helical and icosahedral forms to more complex structures. Most virus species have virions too small to be seen with an optical microscope, about one hundredth the size of most bacteria.

Answer
Why is Self-Directed Learning the Better Approach?
With a variety of methods, for example, goal-based learning, that facilitate the self-directed approach as well as the ability to guide your own learning experience, self-directed learning already seems like the more appealing approach. Let’s delve a little deeper and consider some of the practical benefits of embarking upon a self-directed learning journey and, how this method not only impacts learners but, their organization as well.
The learner has complete control:
By choosing learning activities directly in line with their own interests/meet the needs of their end-goal, learners are more likely to engage with the content and therefore, take away beneficial points of interest to help better perform in their job role.
Rooted in the application of skills:
With SDL, learners are required to grasp the “how” and the “why” rather than the “what”. These acquired skills can then be utilized throughout their role for example, problem-solving, time management and communication skills.
Fosters a collaborative learning environment:
The social element of Curatr allows learners to interact with one another throughout their learning journeys. Subjects, problems and solutions can be debated by all learners and, ultimately, this encourages learners to learn from their colleagues and peers, creating a combined knowledge throughout an organization.
Meets individual learners needs:
SDL facilitates learning at one’s own pace. Relevance also increases because learners are motivated to learn from their own experiences while applying their newly-acquired knowledge to the job in hand.
A more convenient approach:
Through SDL, learners have the ability to learn whenever and wherever – for instance, listening to a podcast in the car, reading a short article on the train. Mobile versions help facilitate this possibility and, learning becomes much more manageable for learners to fit into the working week.
Overcoming the Pitfalls of SDL
Like with any learning approach, there are a few drawbacks to be mindful of when implementing the strategy into your organizations learning environment.
Loss of motivation:
With this approach, learners are now accountable for their own learning and, there is a risk that learners could lose motivation to continue. To overcome this, it offers the reflection feature that encourages learners to engage with their learning content, thinking back on what they have actually learned and the benefits of the learning material from a continuing professional development point of view.

Hi,

I have conducted univariate regression procedure using SPSS Firths regression as I have a small sample size with the dependant variable being a sparse event. This has given me 3-4 variables with P<0.10.
DO I now proceed to perform a multi-logistic regression? If so, do I run Firths regression with all of these variables selected as co-variates or do I perform a more traditional multi-nominal regression model instead?
Any help would be appreciated as I can't find any guidance on this issue.

Answer
Hello Suliman,
You didn't indicate how small a number the less-observed outcome was for your data set. If it's 100 or more, I wouldn't worry at all about using ordinary logistic regression. If 50-80, then LR may be fine if you have only a modest number of IVs in your model. If it's, say, 10 or fewer, then you're better off sticking with Firth method or some adjustment thereto (see link below). There are other, penalty-added methods available; I just don't know how they might perform with your data.
It's possible that someone has done a simulation study that includes conditions that match well to your data set. If not, you could always try that, to be more confident about your ultimate choice.
Good luck with your work.

I ruminated a consideration on this proposal for the last couple of days as Germany is in anticipation of the surge.
To be clear: This is also just a theoretical exercise and – if applied - would count as a desperate measure in the case of patients otherwise not being ventilated at all.
What if the mode of ventilation chosen would not be conventional BIPAP but APRV/inverse ratio PCV?
The control parameters correspond to conventional ventilator settings as follows: P-high (P-insp), P-low (PEEP), T-high (insp. Time), T-low (exp. time) and FiO2. Note that implementing this mode of ventilation with conventional BIPAP, which is possible in some devices, will in some setups require calculation of respiratory rate, which is 60/(Thigh+Tlow). The slightly different terminology as well as specific algorithms for implementation have been characterized and properly published by experts in the field – which I am NOT. There have been promising studies in ARDS which I will attach below.
If one assumes that for two (or more) patients the key treatment goal would be oxygenation with a more liberal approach to CO2 removal, it should be possible to choose P-high, FiO2 and to some degree T-low to achieve safe oxygenation margins for both patients. This would still allow for some inhomogeneity in compliance between the patients as the lung is splinted to a rather high point in the P-V curve by P-high resulting in a high resting volume. This is the proposed “open-lung” aspect of this ventilation mode. Nevertheless, due to the sparse and brief passive pressure relief phases it is believed to go without higher frequency repeated expansion like in conventional PCV, resulting in less energy deposition into the tissue. The repeated overinflation/atelectasis due to inhomogeneos P-V dependencies had been my main concern when thinking about PCV in a shared circuit and a possible result of volutrauma/atelectotrauma in the patients.
In case of inhomogeneous severity between the patients/different disease progression the treatment goal could be set for the more severe patient accepting hyperoxia in the “more well” patient. In terms of CO2 removal a “common ground” target for the patients could be set in wider range of acceptable values, opting for permissive hypercapnia. As the passive release of the lung volume to exhalation in T-low will generate outflow which is cropped at a certain level of peak flow (by setting T-low) when conventionally setting up/adjusting this mode, it might be difficult to assess this control parameter for the individual patient in a shared circuit.
APRV does even allow for spontaneous breathing on P-high in weaning approaches which have been proposed as well. If flow for the device serving two patients would be dialed high enough to compensate for potential maximum inspiratory peak flow generated by both patients in spontaneous breathing, it could be fathomable to even conduct weaning with two spontaneously breathing patients sharing the same circuit.
I write this as I feel we are all staring in a potential abyss, which might force us to make choices that neither of us ever wanted to make.
Hence, this is a THEORETICAL CONSIDERATION and not a recommendation. Also I do not take any legal responsibility if patient harm ensues. I hope everybody understands that. Also probably someone already thought of this. But I thought: Sharing is caring.
Take care and stay strong.

Oncology is a branch of medicine that deals with the prevention, diagnosis, and treatment of cancer. A medical professional who practices oncology is an oncologist. The name's etymological origin is the Greek word ὄγκος (óngkos), meaning 1. "burden, volume, mass" and 2. "barb", and the Greek word λόγος (logos), meaning "study".
Cancer survival has improved due to three main components: improved prevention efforts to reduce exposure to risk factors (e.g., tobacco smoking and alcohol consumption), improved screening of several cancers (allowing for earlier diagnosis), and improvements in treatment.
