<div style="margin-bottom: 18px; margin-top: 18px;">
<span style="background-color: rgba(255, 255, 255, 0);"><strong>The bad news: </strong>New research finds that working at a computer — or on a smartphone or tablet — is actually terrible for your eyes. Extended bouts of screen time cause changes in the tear fluid that keeps your eyes moist, making it more chemically similar to the tear fluid of people with dry eye disease. The<a href="http://archopht.jamanetwork.com/article.aspx?articleid=1878735" style="text-decoration: none;">study</a> appeared this month in JAMA Ophthalmology.</span></div>
<div style="margin-bottom: 18px; margin-top: 18px;">
<span style="background-color: rgba(255, 255, 255, 0);">When we stare at computers, we blink less than when we would while reading a book or doing another task, <a href="http://www.reuters.com/article/2014/06/16/us-screens-dry-eye-idUSKBN0ER2HG20140616" style="text-decoration: none;">according to</a> study author Yuichi Uchino, an ophthalmologist at the School of Medicine at Keio University in Tokyo. We also open our eyelids wider. All that exposed eye leads to more tear evaporation and dried-out peepers.</span></div>
<div dir="ltr" style="margin-bottom: 18px; margin-top: 18px;">
<span style="background-color: rgba(255, 255, 255, 0);"><img src="http://media2.policymic.com/fe11dab870640fbc5106da866b887d51.png" style="border: 0px; height: auto; max-width: 100%; vertical-align: middle;" width="850" /></span></div>

<div style="margin-bottom: 18px; margin-top: 18px;">
<span style="background-color: rgba(255, 255, 255, 0);">Study subjects who spent the majority of their day in front of a computer had markedly reduced levels of a protein involved in keeping the eye moist. That protein, secreted by cells in the upper eyelid, helps make up the protective layer of film, or tears, that seals our eyes with moisture. This is the first study to link the protein with dry eye disease and screen time, despite the fact that computer use has been <a href="http://www.sciencedirect.com/science/article/pii/S0747563207001501" style="text-decoration: none;">known</a>to affect vision for years.</span></div>
<div dir="ltr" style="margin-bottom: 18px; margin-top: 18px;">
<span style="background-color: rgba(255, 255, 255, 0);"><strong>The details: </strong>The researchers analyzed the tears from both eyes of 96 Japanese office workers, about two-thirds of them men, and measured how much of the total protein content of the tears was the critical moistening protein they identified. The longer people spent in front of a computer screen, the researchers found, the less protein was present in their eyes and the drier their eyes.</span></div>

<div dir="ltr" style="margin-bottom: 18px; margin-top: 18px;">
<span style="background-color: rgba(255, 255, 255, 0);"><strong>Why it matters:</strong> An <a href="http://www.aao.org/newsroom/upload/Eye-Health-Statistics-April-2011.pdf" style="text-decoration: none;">estimated</a> 5 million Americans, most of them over 50, suffer from dry eye, a chronic<a href="http://www.aoa.org/patients-and-public/eye-and-vision-problems/glossary-of-eye-and-vision-conditions/dry-eye?sso=y" style="text-decoration: none;">condition</a> in which sufferers don't produce enough tears to lubricate and nourish their eyes. People with dry eyes can feel like their eyes are irritated, gritty, scratchy or burning. Some experience blurred or even permanently impaired vision.</span></div>
<div dir="ltr" style="margin-bottom: 18px; margin-top: 18px;">
<strong>The good news:</strong><span style="background-color: rgba(255, 255, 255, 0);"> People can reduce their risk for dry eye with a few simple changes, such as placing computers at a lower height with the screen tilted upward (to decrease how wide you spread your eyes), using artificial tears and remembering to blink.</span></div>

<span style="background-color: rgba(255, 255, 255, 0);">The Joint Federal and State Team in collaboration with other health organisations on prevention of Ebola outbreak in Lagos, has begun monitoring of the 59 persons that had contact with the victim, who died of  Ebola Virus Disease, EVD, in a private hospital in Lagos, last week.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Addressing a joint press briefing, yesterday, on the update of the Ebola virus disease, Director National Centre for Disease Control, NCDC, Professor Abdulsalim Nasidi, and Lagos State Commissioner for Health, Dr. Jide Idris, explained that out of the 59 persons that had contact with the Sawyer in Lagos, 44 were hospital contacts (38 healthcare workers and six laboratory staff) and 15 airport contacts comprising three ECOWAS staff – driver, liaison and protocol officer, Nigerian Ambassador to Monrovia, two nursing staff and five airport passenger handlers.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Appeal for calm<br style="margin: 0px; padding: 0px;" />Idris, who appealed for calm, said right now, 20 contacts had been physically screened.  “The airline manifest has not been provided by the airline at the time of this report and therefore, the precise number of passenger contacts is yet to be ascertained, especially as two flights were involved Monrovia – Lome and Lome – Lagos. There was no report of medical incident filed and the General Declaration report of the flight.”</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Idris who stated categorically that only one case of imported Ebola and one death has been recorded in Lagos, said: “No Nigerian is infected, but all contacts are being actively followed.  We call on all Nigerians to be calm and not panic and I do hereby assure them that both the state and Federal governments are up in arms to ensure that the virus did not escape and that no Nigeria is infected with this virus,” he stressed.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Preliminary investigation<br style="margin: 0px; padding: 0px;" />It was further disclosed that preliminary laboratory investigation conducted by the NCDC AI virology laboratory of the Lagos University Teaching Hospital, LASUTH, and the Redeemers’ University’s World-Bank Funded African Centre of Excellence for Genomics of Infectious Diseases (ACEGID) detected viral DNA and in both blood and urine samples obtained from the patient were positive for the Pan Filo virus analysis and Ebola Zaire MGB virus strain – specific analysis. Samples were also collected for further confirmation at the WHO, collaborating laboratory for Ebola in Dakar.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Meanwhile, an isolation ward has been designated by the Lagos State Ministry of Health at the Infectious Disease Hospital, Yaba for case management. The designation of three other health facilities was said to be under way.<br style="margin: 0px; padding: 0px;" />Idris explained that adhering strictly to WHO guidelines, the body of the deceased patient was decontaminated using 10 per cent sodium hypochlorite and cremated, with the permission of the government of Liberia. “A cremation report has been prepared for dispatch to the family. The vehicle that conveyed the remains was also fully decontaminated.”</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Nasidi, who allayed fears that EVD cannot be acquired through mere coming into contact with the EVD patient, disclosed that effort to send the packaged sample of the decease to Dakar failed as the courier company turned it down.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">“We were disappointed that the courier rejected the sample. That is why we immediately sought the second opinion of World Health Organisation, WHO, recommended laboratory which is International Centre for Genomics. We are still going to dispatch it to Dakar, most likely first thing today but the WHO has accepted this result.”<br style="margin: 0px; padding: 0px;" />Nasidi explained further that even dead bodies of EVD could be more dangerous in terms of transmission.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Case management<br style="margin: 0px; padding: 0px;" />To ensure appropriate case management and infection prevention and control, he explained that an isolation ward has been designated by the Lagos State Ministry of Health at the Infectious Disease Hospital, Yaba for case management, adding that the designation of three other health facilities is under way.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Further, he disclosed that a total of 100 Personal Protective Equipment, PPEs, have been procured by the Nigeria Centre for Disease Control, NCDC, and Federal Ministry of Health, FMOH and distributed to the private hospital and the state Ministry of Health and WHO also donated 250 PPEs to the NCDC/FMOH.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">On how the corpse was decomposed, the Commissioner said the state adhered strictly to WHO guidelines, the body of the deceased patient was de-contaminated, using 10 per cent sodium hypochlorite and cremated, with the permission of the government of Liberia.  “A cremation report has been prepared for dispatch to the family. The vehicle that conveyed the remains was also fully decontaminated,” he added.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Recognising the importance of involving the community early in the response, he stated that already the various communities, traditional and religious leaders have been alerted about the disease and urged to report promptly to healthcare workers of any suspected case.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Categories of EVD<br style="margin: 0px; padding: 0px;" />Explaining categories of Ebola Virus Disease, EVD, spread, he explained that “those who come in direct contact of excretions of the dead are primary high risk group; the second group are those that come in contact with facilities used to actually treat or handle these patients; the third category are those who come in contact with those who came in very closed contact with the victim or the dead body.  However, the fourth category is those who are within the areas of active transmission of the virus.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">“It is also important we clarify a question of whether any of the contacts has been tested -  the two laboratories are on standby for 24 hours and we have the APIN and the laboratory committee on the group screening one on one, and taking temperature of the contacts twice a day – morning and evening. We are following WHO criteria and the special protocol that you screen only the blood of only those contacts that start developing symptoms.  We are going to identify few of them that we’d already known that came directly in contact with the blood of the deceased while managing him,” he added.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Warning communities that eat bats, he said this is the time for them to desist from consuming it. Similarly, he noted that some communities that worship bats and keep them in their houses should be very careful and stop the act.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Burials<br style="margin: 0px; padding: 0px;" />On burial ceremonies of people who died from EVD, he said it had been shown that 40 per cent of the cases of Ebola virus spread was from the mishandling of the burial of the dead bodies.  He warned that in case of any Ebola death, people should not just go and bury but contact public health officials.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Preventive tips<br style="margin: 0px; padding: 0px;" />President of the Nigerian Academy of Science, Professor Oyewale Tomori, who commended the state government for its prompt response, harped on the rules of hand washing and infection control.  “There is no need for panic if we follow the rules of hand washing and infection control. There is need for Nigerians to be at alert as it is happening within the West African countries. There is absolutely no need to panic, he insisted.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">“Where it has spread, it is because people have abandoned the rules of hand washing and infection control; we shouldn’t have diseases like Ebola if we maintain the rules of hand washing. Where people have followed the rules of hand washing, we must be at alert; we are not out of the wood yet.  We must continue to be at alert. We need to be washing our hands but no reason to panic.” He explained that domestic animals are not carriers of Ebola virus and people who are rearing domestic animals such as pig should not be afraid.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">Also speaking, the Special Adviser to the Governor on Public Health, Dr. Yewande Adeshina urged residents and health officials in the state to report any suspected case of Ebola virus immediately. Adeshina appealed to residents to reduce the risk of contracting the disease by observing high standard of hygiene through washing of hands often with soap and water.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">“Avoid close contact with anyone who is sick and ensure that objects used by the sick are decontaminated and properly disposed because fluids from an infected person are extremely dangerous,” Adeshina urged residents.</span></div>
<div style="border: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
<span style="background-color: rgba(255, 255, 255, 0);">NCAA suspends A_SKY Airline operations to Nigeria<br style="margin: 0px; padding: 0px;" />Meanwhile, the Nigerian Civil Aviation Authority, NCAA, yesterday, said it has suspended all A_SKY Airline operations to Nigeria with immediate effect. The airline flew the Liberian infected with the Ebola virus into Lagos, which has created panic and diverted world attention to Nigeria.</span></div>
