TB is transmitted through the air. The droplet nuclei generated when a sputum positive pulmonary TB patients coughs, mixes in the air and are carried to a susceptible person in the vicinity or by air currents to longer distances. Sputum Negative TB patients may also contribute in transmission of infection to a smaller extent. Now my concern is that, "Can housefly provides an additional epidemiological link to spread TB infection in the community?"

Dear Researchers,
Could you please suggest some public health, psychological and behaviour science journals, considering the following criteria:
1) Scopus indexed
2) No APC (or at least research4life opportunity)
3) Open-access
4) Real fast processing
NB: Impact Factor and Quartile - don't matter!
Relevant answer
Answer
Mosharop Hossian I do not think it is about APC. This is because there are other journals with APC and still not fast. I think it is a deliberate act from MDPI. Also, there are other factors that may influence the processing time.

Relevant answer
Answer
Dear Prof. Denis Korneev, between 2014 and 2016, we had an unknown number of cases of Zika in my country Venezuela. We didn't have any information about the disease, so we thought it was dengue. It was tragic, really tragic. But the Chavista regime banned any information about Zika numbers. I translate for you, extracts of the following link:
"Los médicos afirman que Venezuela tiene ya más de 500.000 casos de Zika por Teresa Santos / Doctors say Venezuela already has more than 500,000 Zika cases" by Teresa Santos." Noticias y perspectivas, May 2016.
"...Venezuelan physicians say the Zika virus is already an epidemic in his country, but the government is reluctant to admit the problem. Data from the Venezuelan Public Health Society and the NGO Red Defendamos la Epidemiología Nacional indicate that between June / July 2015 and February 2016 there were more than 500,000 Zika cases in the country.
In March of this year, the Venezuelan National Academy of Medicine formally declared that the country is facing a humanitarian health crisis. However, the latest epidemiological bulletin published by Venezuela's Ministry of Popular Power for Health (MPPS), dated 2015, does not contain any information on Zika cases in the country...".

In recent research (pdf attached is below) we found that patients with a low educational level became adapted to the prosthesis less frequently.
This was a cross-sectional study. The patients were identified by primary healthcare teams.
The inclusion criterion was that these should be patients who underwent major lower-limb amputations of any etiology. Associations between sociodemographic and clinical variables and the adaptation to lower-limb prostheses were assessed.
We examined 149 patients. Adaptation to the prosthesis occurred in 40% (60/149) of them, but only 62% (37/60) of these were using it.
Adaptation occurred more often among male patients (P = 0.017) and among those who had a higher educational level (P = 0.013), with a longer time since amputation (P = 0.049) and when the etiology was trauma (P = 0.003).
The result from logistic regression analysis showed that only patients with low education (P = 0.031) were significantly associated with a lower frequency of adaptation to prostheses.
What's your opinion and experience about this?
Relevant answer
Answer
I am working at Cancer Center as we do a lot of amputations and I do agree with you, the lower the education level the less frequency of using the prosthesis.

Does anyone know when 5-year age bands were first introduced, and the rationale for their use.
Indeed why are 1, 2, 3, 4-year age bands not used?
Also is anyone aware of research to show that 5-year age bands may be unhelpful when antigenic original sin is behind population counts for deaths or admissions?
Many thanks.
Relevant answer
Answer
Dear Preethy,
You can use any age bands you choose, however, remember that the age distribution between different areas deviates from the chosen standard population as the width of the age band increases. Ideally use single year of age, however, this is limited by the accuracy of the population estimates.
Indeed far better to ask yourself the question what am I attempting to do by age standardization. For example, I have discovered that deaths around the world are showing on/off switching and this on/off switching does not neatly match with calendar years. Calculated age standardized mortality can therefore wildly fluctuate. See http://www.hcaf.biz/2010/Publications_Full.pdf for details.

It has been suggested I put a paper in to publish in AIMS microbiology, however I have yet to find an impact factor for this journal. Has anyone got experience with it? How do I find out it's impact factor?
Relevant answer
Answer
Though a long time have passed since the question was asked, I'll comment it. This year we published two papers in this journal. Yes, it still does not have impact-factor (since it is still too early for this), but is included into the Emerging Sources Citation Index of the Web of Science Core Collection, like many "young" and promising journals.
As for our publications, one was published within a special topic and was free of charge, and the second one was published as a regular paper, and we paid for it a quite reasonable sum (300$). Both papers were reviewed by two reviewers each, and I was quite satisfied by their level and qualification... they really read the manuscripts, and their comments were professional. The reviewers worked quickly, and the total period from the submission to revision, acceptance, and publication was about two months; in my opinion, this is a good result. Communication with the editors and submission/revision process was simple and easy. As a result, I would recommend this journal as a potential choice if you have good-level data and need a rapid publication (if you have extra-level data, you may try a journal with a high impact factor first). I'm sure they will receive their first impact factor soon.

I am writing a book and in it, I mention the epidemiological triangle (sometimes called the public health or infectious disease triad). Where did the formulation come from? Who first described it? The references I have found are not informative but it is clearly a very old idea. I am aware that the idea as applied to animal health was formulated in 1974 by an eminent fisheries biologist, Stanislas F. Snieszko (1902 – 1984) to apply to fish diseases. However, I am sure that there must be earlier versions for human health. So far I have been unable to find them.

Suppose I have a Questionnaire for a Stress assessment that contains 30 questions, each question has 5 answers (0- no stress, 1-mild stress, 2- moderate , 3-High stress, 4- Severe stress). The Total score of the 30 question varies from 0 - 120.
How we can categories the Total score (the range of total score is 0-120) into mild , moderate and severe? Which cut off s should l take for mild, moderate and severe?
Relevant answer
Answer
Hello there,
Please find my answer in the steps given here:
Step #1:
Compute the overall mean score for the items of that variable of interest
Step #2:
Make cutoff points using a calculator (Maximum- Minimum / n). How? In case of a five-point Likert scale, you may, for example, have assigned the value (1) for Strongly Disagree, (2) Slightly Disagree, (3) Neutral, (4) Slightly Agree, (5) Strongly Agree. So in order to make cutoff points, you've to do this simple math, as per the formula stated above: (5-1/3). Upon calculation you will get this value (1.33), right! This is the interval value.
* "Highest" refers to the highest score of the given Likert scale (5, in our example)
* "Lowest" refers to the lowest (1)
* "n" refers to the number of CATEGORIES you intend to create
Step #3:
Do the math for the three categories (Low, Mid & High). How? Just add up the score of your interval value to the three category, as in the following:
Low (1 - 2.339),
Mid (2.34 - 3.669)
High (3.67 - 5)
Step #4:
If you are using SPSS, enter these category-related values by navigating through "Transform", and "Recode into Different Variable". Here you will need to recode the Mean score we've obtained in Step# 1. After you give it a new Name and Label, click on "Old and New Values". A new window will pop up. Select "Range", and then insert the values of the categories given above. You should give a value for each range (i.e. 1 for Range no 1), in the New Value empty field. Then click "Add". Follow the same routine for the other range values of your categories, 2 & 3. Click "Continue", and then "Ok".
Step #5:
Go to the Data Editor page and scroll down to find your new created variable. You'll need to click on Value to make labels. Please add 1 in the Value field, and in the Label field the word "Low", and thus 2 for (Mid), 3 for (High). Click "Add" each time you make a new try, and then "Ok".
That's all.
Cheers,

Hi Narayana
A word of advice about your review, don't forget to consult with or better yet, add a librarian to your review team.  Many librarians have developed special skills in crafting comprehensive search strategies and we also know how to work the different search interfaces. Both Cochran and the IOM (or rather, its new name) recommend working with a librarian for systematic reviews.  There is much more to searching than most clinicians and researchers realize.  Without the search specialist on your team, it is quite likely that you will miss some pertinent stuff.
Good luck on your review.

Relevant answer
Answer
Hi Pierre. Barn owls frequently prey on several different species of rodents including some species not frequently sampled by traditional trapping methods. In this sense, if you want to publicize your results with the local people living in the area  keep in mind that the perception of the population size of rodents by the general public (based on sightings or captures for instance) could be different from the "real" composition and population size of rodents in the area. 
Please see 
Also, since barn owls hunt in open areas (as Motti Charter nicely tells above) they could be susceptible to be killed by cars in roads. This is unfortunately frequent in my region here in Brazil. Have this is mind when you will think about the placement location of the nest boxes. 
All the best!

Foodborne illness is more common in the summer months: why is that ?
Relevant answer
Answer
Dear Dr. Shaimaa
Yes, foodborne illnesses do increase during the summer, and the answer appears to be twofold. First, there are the natural causes. Bacteria are present throughout the environment in soil, air, water, and in the bodies of people and animals. These microorganisms grow faster in the warm summer months. Most foodborne bacteria
grow fastest at temperatures from 90 to 110 °F.
Bacteria also need moisture to flourish, and summer weather is often hot and humid.Given the right circumstances, harmful bacteria can quickly multiply on food to large numbers. When this happens, someone eating the food can get sick.
Outside activities increase. More people are cooking outside at picnics, barbecues, and on camping trips. The safety controls that a kitchen provides -- thermostat-
controlled cooking, refrigeration, and washing facilities -- are usually not available.
Fortunately, people seldom get sick from contaminated food because most people have a healthy immune system that protects them not only from harmful bacteria on food, but from other harmful organisms in the environment. At the same time, FSIS, other government agencies, and food producers go to
great lengths to keep food safe. And, of course, consumers can protect themselves at home with proper refrigeration and thorough cooking of perishable food.

Suppose you want to do an outcome research or progress of patients from a certain disease such as HIV or Tuberculosis.  So you wanted to conduct a secondary data analysis on HIV/Care, Tuberculosis or any other disease related patient data. You request an anonymized data from a hospital, insurance provider, or research organization which has collected the data from a certain patient cohort. Then, you received a dataset which is 5 to 10 years or more years older. Due to the reason that the company which has been owning the data was not legally allowed to share the data 5 or 10 years ago, you couldn't access the data timely.
How much can this data be used in research?  Can the findings from analyzing this data be used to reflect the conditions of the disease in the current patients?
Thank you.
Relevant answer
Answer
Yes you can use old data  in specific situations like the exploration of time trends of events and also in case you want to compare changes over time but at two points in time not as a trend.

Is there any formula or calculator for measuring sample size in rare disease? especially if the researcher work in a medical center for this rare disease with nearly half of country cases
Relevant answer
Answer
Dear Ehab
The sample size of any study is determined by two major factors. The first is the scientific requirements which are tackled by statistical equations. The second is the economics of the study itself ( the resources available to carry out the study). In your case, the sample size and the sampling procedures depends on the type of study you like to conduct, the hypothesis to test and so on. If the condition you talk about is very rare (4/100000) as in case of most cancers for example, the sample size to estimate true prevalence, incidence or mortality is too big to handle. JUst to give you one example. We tried to estimate the annual incidence of all malignant disease in Basrah, the sample size required was huge (say more than 100000 persons). The smallest sample size we used was 41000 persons).
I guess you want to study some features of that disease ( fatality, response to treatment, risk factors...etc) rather than to estimate epidemiological parameter. In this case, the sample size might be within your capabilities.

Considering diet against disease origin since its genetics is very broad, should define something closer to cause-effect relationship, thus only seen as influence and not determinant. As a statistical procedure, we could consider the correlation between the data and then define a hypothesis test according to normality. They are not exclusive and can be used interchangeably

Does anyone know of research/estimates/projections of the numbers of people worldwide who take either insulin or non-insulin glucose lowering drugs, or both? I am aware of major sources, such as the latest IDF Diabetes Atlas and WHO Global Report on Diabetes, which do not provide such information.
Relevant answer
Answer
I hope to cite the latest figures. The USA evidently has good data; eg, in NHANES 2010, 82% of diabetes patients took anti-hyperglycemic medications (Wong HK, et al. Ann Epidemiol 2014;24:516-21), and according to IMS Health data,18.8 million adults filled anti-diabetic prescriptions in 2012 (Hampp C, et al. Diabetes Care 2014;37:1367-74); 63% used metformin. Data quality from elsewhere is surely variable. Conservatively assuming that 415 million worldwide have diabetes (IDF Diabetes Atlas 2015), 50% are diagnosed and 25% to 50% of those treated, the ballpark would be ~50 to 100 million taking anti-diabetes medications, or perhaps higher? However, I'd rather cite hard data than guestimate.

In systematic reviews, there are some registered trials, but the trails are not completed. Should we include them or cite them in the review?
Relevant answer
Answer
I agree with the comments made by Luc Dargis.  If the objective of the review is to assess therapeutic efficacy and/or clinical safety  through pooled data, it may be difficult to access relevant data from incomplete trials because  it is still "work in progress" and not published. However, if you are conducting a study which is yet to be completed, and you have some data available with you, it may be included in the review citing it as your  'personal communication'. Needless to say, use of published data would lend more credibility to the review.

if somebody from a country belonging to Nagoya Protocol implementation, can he/she collect plants from the original country then to study them outside the original country?
Which type of studies require special permission from the original country?
Is it sufficient to add a scientist from the original country on the published works?  
Relevant answer
Answer
Nagoya protocol is still a work in progress
I recently attended a conference on this @ Bern, Switzerland.
As I understand you will have to get in touch with the "contact person" for both the country from which you collect the sample/s, and the country to which you plan to import the sample/s- before scheduling the collection. These contacts are identified and published on the webpage. Any study that requires the collection of organisms/ specimens (plants, animals, insects) will have to go through this.
No, it is not sufficient to just add a scientist!

The degree to which individuals have the capacity to obtain, process and understand basic oral health information and services needed to make appropriate health decisions that is the core of oral health literacy, would like to know how and through what modalities they are carried out around the globe, please share you insights.
Relevant answer
Health literacy is becoming increasingly a crucial area of importance in public health. Firstly, it provides more citizen/client/patient empowerment. Secondly, it helps in compliance with health promotion and education campaigns for prevention of disease as well as compliance with health professional advice. 
One approach that is gaining a great deal of attention is technology and social media in promoting health literacy:
Manganello, J., Gerstner, G., Pergolino, K., Graham, Y., Falisi, A., & Strogatz, D. (2016). The Relationship of Health Literacy With Use of Digital Technology for Health Information: Implications for Public Health Practice. Journal of public health management and practice: JPHMP.
These authors conclude:
"While self-report health literacy does not appear to influence access to and use of digital technologies, there is a strong association with experiences searching for health information and preferences for health information sources. Public health agencies and organizations should consider the needs and preferences of people with low health literacy when determining channels for health information dissemination. They should also consider implementing interventions to develop health information-seeking skills in populations they serve and prepare information and materials that are easily accessible and understandable."

Given the current situation of multiple biological crises represented by emerging and re-emerging diseases, it seems that this trend will continue in the sense that every now and then a new outbreak of disturbing infection will occur. Research to develop vaccines and other international actions and preparedness are essential. In addition, the political turmoil affecting many countries is likely to represent hot spots in the foreseeable future and create long lasting human emergencies. A wise world seems receding.

For a history of Portland Oregon's successful campaign to block the spread of San Francisco's plague epidemic in 1907. The then-recent proof that the vector was fleas primarily, rats only secondarily, must have optimized anti-plague tactics.

Answer
Plague was eradicated in Australia by the 1920s, and eradicated from the Hawaiian Islands by 1960. In both cases plague arrived in the late 1890s, and deliberate public health campaigns targeting infected rodents (not just the black rat) led to plague eradication.

USAMV Cluj-Napoca is the first in Romania to promote the NON-SMOKING CAMPUS.
I ask you to help me to PROMOTE A NON-SMOKING POLICY ON YOUR UNIVERSITY CAMPUS. You are a student, professor, in the senate, please lets VOTE FOR NON SMOKING ON CAMPUS. PROHIBIT SMOKING on campus.
No special places for smoking. No special treatment for smokers.
We can’t construct professionals without educating citizens. Life needs to be protected. Public health needs protection.
We should promote Life and Health. Besides the Human Condition positive results, we reduce resources consumption resulting to a positive Global Economy, to a Sustainable Development and furthermore to overall Ecological Protection.
Please see the article attached available in Files folder of this group.
FILE NAME: USAMV Newsletter 21 tipar Cluj Napoca - Romania - Feb 2011 - cut version- Stop Smoking by ATW see pg15
ARTICLE TITLE:
STOP FUMATULUI LA USAMV CLUJ-NAPOCA, în UNIVERSITĂŢILE din ROMÂNIA şi ORIUNDE în LUME
Pentru o Românie şi o dezvoltare durabilă
EN ) Stop Smoking within USAMV Cluj-Napoca and All Romanian University campuses and Anywhere in the World – for a Sustainable Romania and Development
We can not build one way and destruct the other ways. Education must be sustainable only this way we can hope for sustainable developments, for economic stability and environmental protection.
The article is in Romanian language and is attached to the file folder (please see page 15 of the publication).
The English abstract is enclosed here:
ABSTRACT:
The article is in Romanian language and it marks the beginning of Stop Smoking campaign within the University campuses in Romania, starting with the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. It encourages students and professors to stop smoking on the campus and anywhere. The essential purpose of an educational institution, of a university is to prepare professionals. USAMV Cluj-Napoca being a Life Sciences University has a more accentuated obligation not to only research Life Sciences but also to protect Human Life and its Human Condition. Healthy professionals are a better, sustainable investment.
Stopping smoking assures public health, reduces public expenditures and wasted natural resources. Therefore, smoking has a huge negative impact upon the Global Ecological and Economical problems given the inter-dependence of resources and of the negative outcomes of tobacco consumption. The article is also an invitation to observe 31-st of May as the „Make Every Day World No Tobacco Day” initiated recently by the World Health Organization (WHO). The article calls for initiating in Romania such campaign and the 31-st of May to be a day to celebrate the success.
To mention sadly, it is very difficult to lunch an initiative in Romania.
The article in essence, using Romanian language says: Recent, Organizaţia Mondială a Sănătăţii (WHO), a declarat 31 Mai a fi ziua Mondială împotriva fumatului. Numită „FĂ FIECARE ZI ZIUA MONDIALĂ FĂRĂ TUTUN,.” USAMV Cluj-Napoca poate pre-întâmpina ziua de 31 mai dând un exemplu în rândul universităţilor din România.
I invite readers (and members of this group) to take a stand and send to the University an email or even better a paper letter via regular / registered mail and express your point of view. It is a beginning of a major project and I need any possible support from allover the World and from Romania as well.
It is not a domestic concern; it is not a National concern. It has a Global Impact as the borders that divide us are just symbolic.
Thank you,
