How sleep apnea robs you of a good nights rest

first_img 1 Now playing: Watch this: How to improve sleep using tech 1:04 Comment How to get better sleep in 2019 Tags Causes and risk factors of sleep apneaAn “apnea” is a temporary pause in breathing. In most cases, it’s caused by tissue collapsing in the back of the throat (obstructive sleep apnea). When you fall asleep, the muscles of your upper airway relax. This narrows your airway, making it hard for oxygen to reach your lungs. If you sleep on your back, gravity can exacerbate this narrowing, because your tongue relaxes backward toward your throat. Central sleep apnea is usually linked to other medical conditions, such as heart disorders and brain damage.As far as risk factors, many things can influence your likelihood to develop sleep apnea, the most common and significant being excess body weight. Common risk factors for sleep apnea include:Excess weight: If you have a body mass index (BMI) of 25 or higher, your risk for sleep apnea increases.Large neck circumference: Your risk for sleep apnea is higher if your neck measures 17 inches or more for men, or 16 inches or more for women. This is because a larger neck has more tissue that’s liable to collapse during sleep. Age: Sleep apnea can affect people of any age, but it becomes more common when people reach young adulthood and middle age. Gender: More men get sleep apnea than women. For women, the risk of sleep apnea increases as they approach and go through menopause. High blood pressure: Hypertension and sleep apnea commonly coexist.Family history: If a family member has sleep apnea, your risk is higher, because sleep apnea can be inherited. Alcohol use: Drinking alcohol before bed can cause your throat muscles to relax even further.Smoking: Smoking can increase inflammation in your airways. POLYSOMNOGRAPHYTo be diagnosed with sleep apnea, you might undergo a polysomnography test. AMELIE-BENOIST / BSIP / Getty Images How do you get diagnosed with sleep apnea?In most cases, doctors diagnose sleep apnea based on a careful physical exam, sleep evaluation and sleep history. You may not be able to provide a sleep history by yourself, but you can enlist the help of someone who shares your bed or room.A sleep evaluation usually involves overnight monitoring at a sleep center, where machines measure your breathing and other body functions, such as your pulse, while you sleep. Sometimes, at-home sleep tests are an option. Tests that detect sleep apnea include:Nocturnal polysomnography: During this test, equipment measures the activity of your heart, lungs and brain, as well as your breathing and movement patterns and blood oxygen levels while you sleep.Multiple Sleep Latency Testing (MSLT): An MSLT tests for excessive daytime sleepiness by measuring how quickly you fall asleep in a quiet environment during the day. It’s often used to diagnose narcolepsy.  Maintenance of Wakefulness Test (MWT): An MWT measures your ability to stay awake during the day by finding your sleep latency, or how long it takes you to fall asleep. Sleep latencies of less than eight minutes during the day are considered abnormal.Home sleep tests: At-home tests are usually simplified versions of nocturnal polysomnography that measure your heart rate, airflow, breathing patterns and blood oxygen levels.In some cases, doctors refer patients to sleep specialist or otolaryngologist (also known as an ear, nose and throat or ENT doctor) for further evaluation, which can include a nasal airflow test and an examination to rule out any blockages in your nose or ears.Your doctor might also refer you to a cardiologist or neurologist to look for causes of central sleep apnea. A neurologist may conduct an electroencephalogram (EEG) to measure brain waves and test for central sleep apnea, while a cardiologist can use an electrocardiogram (ECG) to rule out or confirm any heart complications.

Alina Solovyova-Vincent / Getty Images How to treat sleep apneaYou can treat sleep apnea a few ways, and many people go through a series of trial treatments to find out what works best for their sleep apnea. Sometimes, it takes takes a series of trials to find the best treatment, and most people end up using a combination of common equipment, machines and therapies to get relief. Treatment options for sleep apnea include: Continuous positive airway pressure (CPAP): Most people who seek treatment for sleep apnea start with CPAP. You choose a CPAP mask, which sends a pressurized airflow through your throat to open your airways while you sleep. If you use a CPAP, make sure to keep it clean. Bilevel positive airway pressure (BiPAP):  Similar to a CPAP, a BiPAP also provides a pressurized flow of air. The key difference is that it provides two different streams — one as you breathe in, and one as you breathe out.Chinstrap: Usually used in conjunction with a CPAP, chinstraps help you to stop breathing through your mouth. Oral appliances: If you don’t have severe sleep apnea, you could try custom-fitted oral devices that help keep your airway open. Just make sure to get one from a qualified dentist or orthodontist, not a one-size-fits-all appliance from the internet.Usually, your doctor won’t recommend surgery unless all other options have failed to treat and improve your sleep apnea. Most doctors suggest at least a three-month trial of other options before recommending surgery, which can include nasal reconstruction (such as to fix a deviated septum) or removal of adenoids — the soft tissue in the back of your throat. Symptoms of sleep apneaThe most common symptom of sleep apnea is snoring, but snoring on its own isn’t always indicative of sleep apnea. Snoring followed by silent pauses, gasping or choking sounds is likely a sign of sleep apnea. Because sleep apnea wakes you up frequently throughout the night (even if you don’t notice it), you can suffer from symptoms of sleep deprivation, such as daytime fatigue, difficulty concentrating, unintentional napping and irritability or mood swings. Other symptoms include:Feeling tired, even when you thought you had a full night’s sleepInsomnia or trouble falling asleepHeadaches and migrainesLoss of memory Decreased sex driveNocturia (waking up at night to use the bathroom) Complications of sleep apneaWhen you have sleep apnea, your body is consistently deprived of oxygen throughout the night. This lack of oxygen can have negative long-term effects on your health. Sleep apnea has been associated with:Hypertension (high blood pressure) Cardiovascular disease StrokeDiabetes Depression Metabolic syndrome Liver problems Read more: This one tip will help you sleep better tonight 29 Photos Share your voice Sleep Ghislain & Marie David de Lossy/Getty You know the consequences of not getting enough sleep: mood swings, crabbiness, cravings, difficulty focusing and sluggishness. And when you don’t know why you can’t get enough sleep, the symptoms become even more frustrating. The culprits behind sleepless nights range from blue light to parasites — but you might be dealing with something more serious: sleep apnea.An estimated 22 million Americans suffer from sleep apnea, a sleep disorder that causes you to momentarily stop breathing while you’re asleep. With sleep apnea, your airway becomes blocked when your body relaxes during sleep, limiting your lungs to little air flow.Characterized by loud snoring and often choking noises, sleep apnea causes your brain and body to become oxygen-deprived, often leading to frequent awakenings throughout the night. Depending on the case, it could happen a few times per night or hundreds of times each night.This guide goes over the different types of sleep apnea, causes, risk factors and symptoms to help you understand sleep apnea. You’ll also learn how to go about seeking a diagnosis and treatment options if you think you may have sleep apnea.Read more: What’s the difference between REM and deep sleep?Different types of sleep apneaThere are three types of sleep apnea, and the way they manifest in your body is different. But the end result is the same — all three deprive your body of oxygen.Obstructive sleep apnea is the more common form of sleep apnea that occurs when your throat muscles relax, blocking your lungs from receiving oxygen.Central sleep apnea is less common, and it occurs when your brain doesn’t properly signal the muscles in your body that control breathing.Complex sleep apnea syndrome, also known as treatment-emergent central sleep apnea, is the least common of all three. This occurs when someone exhibits signs of both obstructive sleep apnea and central sleep apnea last_img read more

High Inflation Economic Slowdown Hits Indian PC Market Sales Decline by 59

first_imgThe overall sale of desktops and laptops in India has gone down in the third quarter of this year as compared to last year, recent data showed.According to market research firm Gartner Inc, India’s mobile PC market, which totalled nearly 2.9 million units in the third quarter of 2012, recorded a fall of 5.9 percent during the corresponding period last year.”Consumers accounted for 47 percent of total PC sales in the third quarter of 2012 compared to 55 percent in the third quarter of 2011,” said Vishal Tripathi, principal research analyst at Gartner.”This emphasises the fact that despite the festive season and availability of various end user schemes on PCs, the market was impacted by high inflation, global economic uncertainty and limited share of wallet as consumers preferred to spend on other consumer durables,” he added.In the third quarter this year, parallel imports and white boxes which accounted up to 47 percent of the whole desktop market showed a decline of 35 percent as compared to the same period of the previous year. Mobile PCs helped drive overall market growth with a similar 23 percent growth on a year-on-year basis. Lenovo retained the top position in the third quarter of 2012 with help of factors like the execution of the Tamil Nadu government order, and a strong increase in the consumer space. While HP’s PC shipment grew around 10 percent, Dell declined 22 percent compared to the third quarter of 2011. For local vendor’s like HCL PC market share declined to 3.4 percent in the third quarter with a 43 percent year-on-year decline from the third quarter in 2011. Acer, Dell, HP and Lenovo represented around 60.6 percent of the market.last_img read more

Stanford group creates miniature selfcontained fluorescence microscope

Explore further Microscope could ‘solve the cause of viruses’ More information: Miniaturized integration of a fluorescence microscope, Nature Methods (2011) doi:10.1038/nmeth.1694AbstractThe light microscope is traditionally an instrument of substantial size and expense. Its miniaturized integration would enable many new applications based on mass-producible, tiny microscopes. Key prospective usages include brain imaging in behaving animals for relating cellular dynamics to animal behavior. Here we introduce a miniature (1.9 g) integrated fluorescence microscope made from mass-producible parts, including a semiconductor light source and sensor. This device enables high-speed cellular imaging across ~0.5 mm2 areas in active mice. This capability allowed concurrent tracking of Ca2+ spiking in >200 Purkinje neurons across nine cerebellar microzones. During mouse locomotion, individual microzones exhibited large-scale, synchronized Ca2+ spiking. This is a mesoscopic neural dynamic missed by prior techniques for studying the brain at other length scales. Overall, the integrated microscope is a potentially transformative technology that permits distribution to many animals and enables diverse usages, such as portable diagnostics or microscope arrays for large-scale screens. Citation: Stanford group creates miniature self-contained fluorescence microscope (2011, September 12) retrieved 18 August 2019 from https://phys.org/news/2011-09-stanford-group-miniature-self-contained-fluorescence.html (PhysOrg.com) — A team of researchers working at Stanford University have devised a means for building the smallest self-contained fluorescence microscope ever. Weighing just under 2 grams and slightly larger than the end of a pencil, the new microscope is small enough to attach to a mouse head, which means researchers can watch the mouse brain in a natural setting. Led by Mark Schnitzer and Abbas El Gamal, the team describes its findings in Nature Methods. One downside to the new microscope is that its resolution isn’t quite as good as standard bench models; 2.5 microns as opposed to 0.5. But it does have a larger field of view, which means that most serious labs would likely want to have both types of microscopes, depending on what is being studied.While it’s difficult to say what new discoveries might be made with a microscope that allows researchers to watch a mouse brain in action (on a computer screen) as the mouse goes about its normal activities, it’s probably safe to say, that many of them are likely to be quite illuminating.Schnitzer and some of his colleagues have founded a company they call Inscopix to develop the new microscope and bring it to market, thought they can’t say yet, when that might be. © 2011 PhysOrg.com Till now, most brain researchers have had to use so-called bench-top microscopes, which are what they sound like; microscopes that sit on a bench. This requires that specimens be brought to the microscope (and held still) for examination. This new microscope turns that whole process around in that it allows the microscope to be brought to the specimen, allowing researchers to study the brain in ways that have not been possible before. The team reports that they have already discovered new capillary dilation properties in mouse brains.The fluorescence microscope differs from traditional microscopes in that it looks at material that has a fluorescence property, i.e. is fluorescent (the emission of light by a material when exposed to radiation). To take advantage of this property specimens must be either naturally fluorescent (such as certain proteins) or stained with a fluorescent material. The approach is similar to that seen when a black-light is used to illuminate semen or blood samples at crime scenes. The light sources used in a fluorescence microscope are typically xenon arc or mercury-vapor lamps.The miniaturized microscope developed by the team is comprised of mass produced parts, which the team says will allow for it to be mass produced at a much lower cost than standard bench-microscopes, opening the door to research at places that have up till now lacked the funds to purchase the more expensive equipment.

Irate CM lashes out at Manekas comment on death of Lalgarh tiger

first_imgKolkata: Chief Minister Mamata Banerjee on Wednesday reacted sharply to Union Women and Child Development minister Maneka Gandhi’s comment on the killing of the Royal Bengal tiger in Lalgarh.Calling the incident a deliberate attempt to malign the state government, Banerjee said that Gandhi should apologise to the tribal people for her derogatory remarks. The Union minister has insulted the Adivasis, Banerjee said.”I am saddened that a Union minister has made unwarranted comments about a community. She said that Adivasis are poachers and they torture animals. I feel she should apologise to the Adivasi community,” an irate Chief Minister maintained. Also Read – Heavy rain hits traffic, flightsShe further went on to say: “I completely condemn the statements made by the Union minister. Adivasi brothers and sisters are our assets. Is she aware how many forests and deep forests are there in Bengal?” Banerjee also raised a question on how Gandhi knew that the tiger was killed by Adivasis. “Common people were living in fear for over a month. Police and Forest department officials took all measures to capture the tiger. Drones were used by the Forest department to catch the animal. Villagers who went to collect kendu leaves in the forest were also injured by the animal. Two persons are still undergoing treatment at the hospital. One should know about Bengal’s culture and its people before commenting on an issue,” the Chief Minister reminded. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedLaunching a scathing attack on the BJP, she said: “During elections they use Adivasis armed with bows and arrows. They hold Ram Navami rallies with arms. Don’t they feel ashamed then? A few days ago, they had brought Adivasis from Jharkhand, armed with bows and arrows.” At a time when Dalits are being persecuted across the country, her comments reflect BJP’s stand on SC/STs, Dalits, Adivasis and common people of the country, Banerjee added.”She must apologise to the nation. Bengal has a rich culture and heritage. She has no right to insult Bengal and Adivasis. We will not tolerate it. People of Bengal will give a fitting reply,” Banerjee stated.”Did she use a telescope? A tiger died and curious people came to see it. Even when people die, relatives and others come to pay their respects. How can she compare this with Shikar Utsav? She cannot ridicule a tradition of the Adivasi community,” the Chief Minister said.It may be mentioned that Gandhi had said earlier in the day that Bengal is the only place in the country where illegal killing of wild animals is “allowed and encouraged”.last_img read more

Govt to introduce stricter laws to check spitting littering in public places

first_imgKolkata: The state government is set to introduce stricter laws by amending the existing ones to check spitting and littering in public places, to ensure a “clean and green” Bengal.A high level committee headed by Chief Secretary Malay De has been set up, to prepare a plan of action to ensure the same. The other members of the committee are Home Secretary Atri Bhattacharya, Director General of Police Virendra, Additional Chief Secretary of the Health and Family Welfare department Rajiva Sinha, Additional Chief Secretary of the state Environment department Indevar Pandey, Commissioner of Kolkata Police Rajeev Kumar, Principal Secretary of the Public Works Department Arnab Roy, Principal Secretary of the state Urban Development and Municipal Affairs department Subrata Gupta, Secretary of the Housing department Onkar Singh Meena and Commissioner of the Kolkata Municipal Corporation (KMC) Khalil Ahmed. Also Read – Rain batters Kolkata, cripples normal lifeAt the same time, the state government will carry out a massive campaign to create awareness among people. Moreover, police will also be keeping a watch and inform if beautification of any waterbody needs to be carried out at any place. On Tuesday, Chief Minister Mamata Banerjee held a high level meeting at Nabanna in this connection. Firhad Hakim, the state Urban Development and Municipal Affairs minister and Aroop Biswas, the state Public Works Department minister, held a Press conference after the meeting. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedWhile addressing a programme outside Nabanna, the Chief Minister urged local clubs to take steps to keep their respective areas clean. Hakim said: “Chief Minister Mamata Banerjee has said in the meeting that we have to take this (checking spitting and littering at public places) as our next challenge. Massive infrastructure development including projects like setting up of skywalk and floating market is taking place in the city. But there is a section of people who spit at and litter public places. We have to keep in mind that it is our state and it is our duty to keep it clean.” “We will carry out a massive statewide campaign to ensure a green and clean Bengal. At the same time, policemen will be informing if beatification of any waterbody under the jurisdiction of respective police station areas is needed,” Hakim said, adding that steps would also be taken for better solid waste management. The modern technology available for the same will also be looked into. Hakim further said that Biswas has been given the responsibility to check the same in state-run hospitals. It may be mentioned that a person was slapped with a Rs 1,001 fine for spitting inside the recently inaugurated skywalk at Dakshineswar.last_img read more

The Health Care Industry

first_img 6 min read Register Now » When a client checks out a health care site, he is looking for information on physicians, insurance policies the health care provider accepts and medical information about the health concern he has.The EssentialsA health care site should provide easy access to information via menus designed consistently throughout the site. Redesign is a good idea if it’s not been updated for two to three years. Ask your web professional for a fresh design using “CSS” (cascading style sheets) rather than “tables.” This will not only make you sound like an expert, it will help you later on as you focus on improving your site’s search engine optimization (SEO).Have a statement on the home page that also lets the customer know why they should use your business. What sets your services apart and why should they visit your site again? A medical news feed with RSS subscription capability should exist on the homepage as well as the medical facility’s news.Make sure to have complete and up-to-date information on all physicians and health care providers, preferably including contact information for each, a photo and basic background info. This should be on a separate page or pages separating physicians by specialty/department. Also, if different physicians accept different insurance policies, make sure to include that information.Your site needs to become a health resource for the community it serves. Make this a main objective of your site’s concept, strive to become a local authority on health care issues and your traffic will increase exponentially.Update the content on your site monthly especially the homepage. As a rule of thumb update the look and feel of the site every one- to-two years. Don’t get stuck in a hosted content management system with limited capabilities–make sure your web developer is able to add functionality to the site easily as your organization grows, and that he or she is willing to consider other options besides a content management system.Hire an SEO professional with a proven record and ask that he or she concentrate on location(s) to drive searches in the area along with the specialties of the business in order to drive searches by longer-distance customers.Mistakes to AvoidMost medical websites that are not successful in converting customers and not successful on the web have the following issues:Bad design. Messy layouts and inconsistent menus cause visitors to feel lost in your site and surf away in frustration. The site needs to be easy-to-read and aesthetically pleasing (e.g., if your customers are older, consider using white background and larger text). Consult with a web development firm and have them tell you what they can do to improve your site, these services are often complimentary.The site development included “frames.” This is frowned upon by the majority of the search engines out there. A site redesign and SEO is highly recommended.A good site is updated regularly and visitors will notice if it’s not. They won’t feel the need to come back, and repeat website customers relate directly to conversion numbers. Empower people in your organization–make them a part of updating the site rather than having a single individual responsible for the entire site.If your content is insufficient and inaccessible or if most of your content consists of bulleted lists, it’s time to look at reorganizing it and adding more content. There’s no such thing as too much content when it’s properly organized. Make sure each physician has a photograph, contact info and basic bio added to the site. If needed, consider using a professional copywriter who specializes in website copy and can work with your SEO specialist.No search engine visibility. From content to design issues, SEO professionals are often able to tell you what your site really needs. Consider this just as important as having a site designed.Poor marketing. Just like in traditional marketing, you need to have a web marketing plan in place and make sure it drives the customers to the site and provides you with web traffic statistics so you know what’s driving traffic.Places to BeDefinitely promote your site and blog to the search engines and most of the web directories including DMOZ. Stay out of link farm sites. Your SEO specialist will also recommend local sites and blogs where a listing or comments may be beneficial.Look for forums where specific conditions you specialize in are being talked about and offer advice without making it seem as though you’re trying to win business in doing so. In your signature on the forum response add the address of your site and blog as links if permitted. There’s a fine line between a well-crafted response and one that will be perceived as trying to spam the forum.”Medical News” with RSS feed, and “Company News” with an RSS feed should be on the homepage of the site. A blog not only will help promote the site, it will also help provide content for feeds (the homepage company news could use the feed provided by the blog). Feeds like these are great as they can then be syndicated by other sites giving you a much larger exposure or footprint. E-newsletters are fine but the ROI is definitely lower than a blog. Press releases should always be included in the company news as excerpts and/or blogged about and a link given to the page or pages on your site where the full text of the release should exist.Keep in mind that the blog will be read by your customers and not medical professionals, so try to keep their interest up with catchy titles and don’t get hung up on medical jargon.Ask you SEO professional to make sure that your blog has the social networking links shown after each post so your readers can help promote your site. And always ask your employees to frequent and comment on your blog and site, as sometimes their input can be very valuable.Researched and written by Liz Wilson.
