Better imaging with Optofluidics

What is Optofluidics ?

Optofluidics refers to manipulation of light using fluids, or vice-verse, on the micro to nano meter scale. Optical devices which incorporate liquids as a fundamental part of the structure can be traced at least as far back as the eighteenth century when rotating pools of mercury were proposed as a simple technique to create smooth mirrors for use in reflecting telescopes. The field of optofluidics is a “marriage” of nano-photonics and micro-fluidics! The introduction of liquids in the optical structure enables flexible fine-tuning and even reconfiguration of circuits such that they may perform tasks optimally in a changing environment.This allows for enhanced optical detection in lab-on-a-chip systems with a potentially strong impact on bio-technology, life-sciences, and bio-medical/health-care industries.It is used in a broad spectrum of military and civilian applications for imaging, spectroscopy, communications, sensing, and displays.

The technology has now allowed the introduction of an inexpensive and high-resolution microscope that has been engineered to fit onto a single chip ( See Optofluidic microscope shrinks to fit on a chip.) The performance of the device is comparable to a 20x microscope, but in terms of size, cost and ability to mass produce, the device has significant advantages.

• The lack of optical elements in the arrangement implies that there are no aberrations to worry about.
  
• This is an intrinsically space-conserving method.
  
• The entire chip is illuminated from above; sunlight is sufficient.

This portable and cheap device is particularly appealing for third-world applications where it could be used in the field to analyse blood samples for malaria or check water supplies for pathogens. In the future, the microscope chips could be incorporated into devices that are implanted into the human body. Pretty good.

An on-chip implementation of the optofluidic microscope.

In the set-up, a voltage of 25 V is applied across the inlet and outlet of a microfluidic channel that is 2.4 mm long, 40 µm wide and 13 µm high. The electric field draws the specimen across the aperture array in a steady stream. The array consists of 120 holes with a diameter of 0.5 µm and separation of 10.4 µm, fabricated on a 2D CMOS imaging sensor. The sensor comprises a grid lattice of 1280 x 1024 square pixels with a pixel size of 5.2 µm.

Improved E.M.Rs to support Health Rights for All.

Image via Wikipedia

Heres more evidence of how good use of Health care I.T can lower health care costs, and bring health care services closer to all, without discrimination. This study quantifies the enormous savings that can be generated by a simple introduction of one more option within Electronic Medical records to choose the lowest cost generic amongst a list of pre-selected generics ( to ensure quality).

” Electronic prescribing (e-prescribing) systems that allow doctors to select lower cost or generic medications could save $845,000 per 100,000 patients per year and possibly more system-wide, according to findings from a new study. Complete use among physicians of e-prescribing system with formulary decision support could reduce prescription drug spending by up to $3.9 million per 100,000 patients per year, according to the researchers”

Doctors using e-prescribing with formulary decision support, which accounted for more than 200,000 filled prescriptions in the study, increased their use of generic prescriptions by 3.3 percent. These changes were above and beyond the increased use of generics that occurred among all doctors and the already high rate of generic drug use in Massachusetts. Based on average costs for private insurers, study authors estimate that the use of e-prescribing could save $845,000 per 100,000 patients per year and generate even higher savings with greater use.

Researchers found that the doctors who wrote electronic prescriptions were slightly younger and more likely to be female than those who did not. In addition, internists, pediatricians, and family physicians made up nearly three-fourths of those who used e-prescribing. Of the 17.4 million prescriptions filled over the course of the study, about 212,000 were prescribed electronically. This study was funded in part by the Agency for Healthcare Research and Quality (AHRQ) (HS15175).”

More use of I.T in health care will have a cascading effect on Health Rights for all as it increases affordability, efficiency, quality and information accessibility of health services. And these are few of the basic requirements of Health Rights for All.

Kindle in Medicine

Kindle is a new device that is changing the face of reading. The best of the current lot of e-book readers, Kindle is a boon for medical students and professionals, allowing them access to hundreds of books on the go!. Kindle, now in its third avatar, the Kindle Dx (Deluxe) boasts of advanced features, like PDF support (experimental) , longer battery life, 5-way Controller and sleeker design.

Check out more features here.. You can view it from all angles, zoom into any area and look at its features.

Using Kindle in Medicine

* Easy for medical students to keep up with all their scheduled reading. You can download and read reference materials that you have read previously to refresh your memory.You can seek out new textbooks to look for answers too.
* Seeking out symptoms, conditions, and other relevant information is easy.You can view photos on the Kindle if you need to see pictures of various signs and symptoms conditions.
* Study medical texts and highlight portions of texts / make notes on the Kindle as you go. Zoom into images for micro details.Bookmark and annotate important portions.
* Research can be done on its built-in web browser ( experimental feature) , no need to carry a laptop to access the internet.It offers free Wireless access to Wikipedia
* .Multiple books can be read at once, no need to carry a JUMBO Grey”s anatomy or Robbin”s Pathology encyclopedias !! It boasts of storage capacity of 1500 / 3500 books, depending on the Model.
* You can listen to music while you read.
* Inbuilt Text-to-Speech feature lets you listen to your favorite books.

It has a clear policy for returning the instrument or any content bought ( within 7 days of purchase) and also One year limited warranty. The kindle library boasts of more than 300,000 books for download, and many more added regularly. Priced at 300 and 500 $$ , and weighing approx. 300 and 500 grams (depending on the model) it is still too pricey for open embracing of this technology. Some libraries have started lending out Kindles ( with preloaded content) to its patrons.

Personally speaking , i can see a lot of content being adapted for Kindle, provided the machine becomes less expensive.
Also , many more wireless features ( like chat, email, videos etc) need to be added. If more such functionality is added to justify its high prices, i expect a LARGE number of medical students turning to Kindle.

Swine Flu guidelines from India

On 14 th august, Friday night, after facing flake for the past two weeks on the bungled handling of Swine Flu epidemic in India, the government has come up with a better set of guidelines.The new guidelines allow ALL doctors to treat for Swine Flu (Believe it or not, earlier only designated hospitals and doctors  < and no other doctor> could treat Swine flu!!) The guidelines were finalized after a five-hour meeting chaired by Health and Family Welfare Minister Ghulam Nabi Azad.

The patients have been categorized as follows:

* Category A: Patients with mild fever plus cough/sore throat with or without body ache, headache, diarrhoea and vomiting. They do not require Oseltamivir and should be treated for the symptoms mentioned above. The patients should be monitored for their progress and reassessed after 24 to 48 hours by the doctor. No testing of the patient for H1N1 is required. Patients should confine themselves at home and avoid mixing with the public and high risk members in the family.

I agree with this

* Category B: (i) In addition to all the signs and symptoms of Category A, if the patient has high grade fever and severe sore throat, he/she may require home isolation and Oseltamivir; (ii) In addition to all the signs and symptoms of Category A, individuals having one or more of the following high risk conditions shall be treated with Oseltamivir: children under five, pregnant women, those above 65 years, those with lung diseases, heart disease, liver disease, kidney disease, blood disorders, diabetes, neurological disorders, cancer and HIV/AIDS; Patients on long term cortisone therapy. No H1N1 tests are required for Category-B (i) and (ii). Such patients should confine themselves at home and avoid mixing with the public and high-risk members in the family.

I think all such cases be tested for H1N1, and antiviral therapy started without delay

* Category C: In addition to the symptoms of Categories A and B, if the patient has one or more of the following: breathlessness, chest pain, drowsiness, fall in blood pressure, sputum mixed with blood, bluish discolouration of nails; irritability among small children, refusal to accept feed; worsening of underlying chronic conditions. Such patients require testing, immediate hospitalisation and treatment.(

All such patients should be started on antivirals without even waiting for test results!!, its already late!

)

During the meeting, various guidelines and protocols developed by the World Health Organisation, Geneva, the Centre for Disease Prevention and Control, Atlanta, United States, and the National Health Service, United Kingdom, were also discussed.The death toll has already reached 26 today, and is rising exponentially. Hope these guidelines help, but i really think its too little too late.

Indian hospitals ranked for Digital media use

The Cybermetrics Lab recently published their world ranking of hospitals, taking into account the institutional activities in field of e-knowledge and their use of digital media for communications

Supporting Open Access initiatives, electronic access to scientific publications and to other academic material are our primary targets…The Web covers not only only formal (e-journals, repositories) but also informal scholarly communication.

The Web indicators measure electronic contents, especially those used for scholarly communication, but also basic information about the hospital, its organization, services and personnel. The rank takes into account both the volume of information published and the impact or visibility of such contents measured by the number of external links the web pages receive from others. As expected, about 45 % of top 200 and 38% of top 1000 hospitals are situated in North America.

The Laparoscopy hospital at N.Delhi is the only Indian hospital to figure in the top 100 hospitals from Asia ( 47/100, Asia), and also the only Indian hospital in top 500 worldwide. Amongst the others, Sir Gangaram hospital scores much better than Apollo and Tata Memorial.

L.R.S Institute of Tuberculosis and respiratory diseases records a very enviable world rank of 19, in number of papers and citations visible on Google Scholar., a noteworthy list headed by The Institute of Cancer Research, London.

Below is the list of 9 hospitals from India amongst the first 2000 worldwide , and their world rankings ( as per Cybermetrics Lab).Individual Ranking in various categories for India

Use your cell phone to diagnose diseases.

Microscopy provides a simple, cost-effective, and vital method for the diagnosis and screening of hematologic and infectious diseases.It is an essential tool in disease diagnosis and widely used all over the world. Unfortunately, the EXPERTISE required to use the tool, and to evaluate the findings is not very common. One requires a pathologist with many years of experience to make sense of those seemingly random and confused pixels. ( I know, i am a pathologist

But the advent of digital imaging has solved many of our troubles. Telepathology made sure that we do not need a pathologist physically present at the site, to render a diagnosis. But microscopy and digital imaging of the biopsy/tissue fragment was still a hassle. Now we have done better. You don’t even need a microscope to send a microscopic image over the network!!Researchers from the Univ. of California worked with high-powered LED – which retails for just a few dollars – coupled with a typical camera phone to produce a clinical quality image sufficient for detecting in a field setting some of the most common diseases in the developing world.

The newly developed technology, CellScope, allows for average cell cameras to be retrofitted with powerful microscopes, able to detect malaria parasites, and even fluorescent marker-stained tuberculosis bacteria.Thus you have your humble cell-phone transformed into the “cell-scope”.

(a) Thick smear of Giemsa-stained malaria-infected blood. (b) Thin smear of Giemsa-stained malaria-infected blood. (c) Sickle-cell anaemia blood smear. White arrows point to two sickled red blood cells. Scale bars are 10 µm.

“The images can either be analyzed on site or wirelessly transmitted to clinical centers for remote diagnosis. The system could be used to help provide early warning of outbreaks by shortening the time needed to screen, diagnose and treat infectious diseases,” University of California in San Francisco (UCSF)/UCB Bioengineering Graduate Group graduate student David Breslauer adds

Physiology of Propofol in drug Abuse

Is Propofol, or Diprivan what Michael Jackson Used for ( Drug) Abuse ?

According to Cherilyn Lee, a registered nurse who operates a Los Angeles-based nutritional counseling business, in California, “Jackson was complaining of insomnia and pleaded for her to get him some (Diprivan)”. Other reports claim Propofol was recovered from his residence. This conversation reportedly occurred in April of this year. Preliminary reports say that M.J died of cardiac arrest, which is within the possible effects of unmonitored Diprivan use. (A rapid bolus injection can result in undesirable cardiorespiratory depression including hypotension, apnea, airway obstruction, and oxygen desaturation.)

Diprivan is a general anesthetic, used to start or maintain anesthesia during certain surgeries, tests, or procedures. It is available in a white vial of 20, 50 and 100 ml (containing 10mg/ml.).Most adults require 2 to 2.5 mg/kg of the drug ( approx. 10 ml). DIPRIVAN Injectable Emulsion is an IV sedative-hypnotic agent and can cause potentiation of other narcotic drugs and benzodiazepines when used together. The most common side-effects include Change in mood or emotions; dizziness; drowsiness; lack of coordination. It is given intravenously, usually within the operation theater or in a clinic. It has a rapid onset of action ( less than 1 min) and short duration of action (approximately 10 min but is dose dependent).It has direct cardiodepressant effects, leading to decreased blood pressure and heart rate in higher doses. Its actions causing decreased heart rate and respiratory rate mean that use of propofol is done only under continuous monitoring of vital signs.Diprivan is not meant for use in pediatrics and elderly population since its safety has not been established in these populations. Prolonged use of propofol results in accumulation of the drug in body tissue and increases the duration of action as well as chances of overdose.

Rarely, Cases of death due to propofol have been discussed in medical literature. All these cases have occured in hospital settings only.It is definitely not meant for home use and this is the first time I have heard of Diprivan being used as a drug of abuse outside hospital settings.

Euphoria, sexual hallucinations and disinhibition have been described on recovery of propofol anaesthesia. These effects could explain the recreational use of the drug. Moreover, several experimental studies strongly suggest the potential for abuse and dependence on propofol,and few cases of abuse and dependency have been described, mostly in medical professionals. As propofol is generally not recognized as a substance of abuse, and because of its safe profile, it is important to remember that rare adverse reactions of propofol could produce death in a context of abuse, even at therapeutic dose range, in the absence of ventilatory and medical assistance.

Scientic animations awards ceremony, China

The 1st Annual International Science Animation Awards being held August 8th 2009 in Guiyang China

Deadline for DVD submissions to “Sci-An” Awards is July 15th 2009

Guiyang, China (PRWEB) June 17, 2009 — Honoring the works of visual wonder that depict what science perceives beyond our eyes, The 1st Annual International Science Animation Awards (ISAA) are being presented in Guiyang, China August 8th 2009.

The ISAA “Sci-An” will be awarded for 2D and 3D works that demonstrate both the highest achievements in scientific and medical communication and superb attention to aesthetic, creative and technical presentation

” This is an industry that will grow exponentially with the compounding demands from various science sectors in the years ahead “

This year marks the first in what will be an annual juried salon, bringing together in China the work of scientific animators from around the world. Professional and student work is welcome, and will be judged separately.

The event will include presentations and panels with industry leaders from across Asia, the United States and Europe.

The two judging categories are commercial and educational, in short form of under three minutes’ run time. Long form work and compilations from longer projects may be entered and will be evaluated separately.

“The need for recognition in this dynamic emerging field has grown to the point of launching this inaugural event” said founding co-chairman, Sander Johnson, who with founding co-chair, David Bolinsky initiated the concept for this international forum at last year’s Guiyang Animation Festival, in Guiyang, China. That festival is the launch for this year’s Sci-An Awards, which will next year become an independent event.

“Hosting this unique forum and awards ceremony in China truly invites pan-Asian and East-West interaction with leaders in the industries and major universities” said Bolinsky, a leading American creator of 3D scientific animation for Harvard University Medical, the Smithsonian, most major pharmaceutical companies, NOVA and additional broadcast clients. “And it promotes further advances in these various industries of science and animation”.

ISAA General Secretary, Liuyi Wang, founding Director of China’s Asian Youth Animation & Comics Contest sees great benefit in highlighting achievements in these advanced new fields of science animation as 21st Century career paths for talented young computer animators. “This is an industry that will grow exponentially with the compounding demands from various science sectors in the years ahead” said Wang.

ISAA “Sci-An” Awards will be given to first, second and third place, plus awards of merit and best in show. The judges this year will include David Bolinsky, XVIVO Scientific Animation Partner; Jane Hurd, Hurd Studios Founder; and Elizabeth Rega, chief anatomical consultant Walt Disney Feature Animation and SONY Pictures Imageworks, with prominent Asia judges to be announced soon.

Deadline for submission is July 15th 2009 and entries cannot be returned.

In welcoming all applications; there are no entry fees required with submissions.

Why US needs healthcare Reforms.

Health care reform is a hot topic these days. What is health care reform? The President, Congress and people like you are talking about it. The simple answer is well, there is no simple answer.

Most Americans i know are not even sure if Healthcare is a fundamental human right ! So talking about “Health care for all” seems too far fetched for them.The argument i hear commonly says that only taxpayers should be given health care assistance and the 46 million or so people without Health insurance can go to Hell ! It seems like a weeding out plan for poverty. ” You don’t have money to buy insurance? Too bad, go sit there in a corner and die”.

All of us shall soon have to come to the conclusion that health rights are equal to Right to life and inability to pay for it cannot be a hurdle. The real problem is not the poor, it is the absurdly rising COST of health care!

A few ways to reduce healthcare costs include

• More Use of Technology
• Empower people with More information
• Payment to care providers to be based on Quality rather than the number of investigations performed. ( This is very basic actually)
• Promote healthier Lifestyle.
