REPOST: Malawi's success story in reducing HIV infection

Malawi has been seeing a decrease in the number of HIV-related deaths and infections recently. The Guardian discusses further the details of this medical success.

Margaret Chiyabwa sits behind a wooden desk, piled with papers and packets of antiretroviral drugs (ARVs). She is filling in a green patient card. It's raining outside and the room at Bvumbve health centre in rural Thyolo, a district in southern Malawi, is crowded and stuffy. Men, women and children queue along the wall, waiting for a check-up, or to collect medicine. Outside, more people squeeze under the roof of a brick walkway connecting two of the health centre's buildings to shelter from the showers. It's not yet 9am.

This is a quiet morning, says Chiyabwa, a Médecins Sans Frontières (MSF) nurse, as she assesses whether the patient sitting in front of her, who is HIV-positive, should have her viral load (VL) tested.

Around 35,000 people are on ARVs in Thyolo, which has an HIV prevalence rate of more than 14%, higher than the national average of around 10%. By the end of June, 14 of the 27 health facilities in the district, supporting around 75% of ARV patients, were offering VL testing.

"After six months on treatment, we will be asking to test patients' viral load," says Chiyabwa. "It's a good thing because those with a high viral load, we are able to assess if they should go on second-line treatment, before it's too late for them."

Unlike CD4 cell counts, which monitor immunity levels, VL testing detects the level of the HIV virus in the blood, which indicates the extent to which treatment is working. This information allow doctors to determine whether to change treatment if levels are too high, before a patient's condition gets too serious – moving them from first-line to stronger second- or third-line drugs, for example – and also stops patients being put on more expensive drugs unnecessarily.

While the cost of first-line drugs has fallen significantly, from about $10,000 (£6,100) per person, per year in 2000, to about $140, second-line treatment is more than double that amount, at about $300, while third-line treatment is more than £2,000.

VL testing is being heralded as the gold standard in monitoring the virus. This year the World Health Organisation recommended its use to monitor HIV at six and 12 months after the start of treatment, then at least every 12 months after that. However, high costs and the difficulty of introducing the VL technology in poor, rural settings, means this is not an option in many developing countries. According to MSF, laboratory-based tests can cost up to $72 per test result, out of reach of many government budgets.

In an MSF survey of 23 developing countries last year, viral load testing was widely available in only four. MSF said there was an urgent need for simple and affordable viral load technologies that can be used in district laboratories, clinics and communities. There are also calls for more HIV funding to be used to develop new tools and treatments for local health facilities.

Getting tested

At Bvumbve, up to 30 people a day are having their viral loads tested as part of a three-year MSF project funded by Unitaid, a global health initiative funded in part by levies on airline tickets.

The MSF project is evaluating the effectiveness of different viral load and CD4 testing technologies in seven African countries with high rates of HIV – Lesotho, Malawi, Mozambique, South Africa, Swaziland, Uganda and Zimbabwe – to see what works best in poorer settings.

Madalitso Nkumbi, 33, a mother of two, is waiting for a blood test. She discovered she was HIV-positive in 2008, after attending an antenatal clinic when she was pregnant with her second child. She's been living well on ARVs ever since, but is pleased to be offered the viral load testing.

Nkumbi's husband left her when he discovered she was HIV-positive, so she needs to keep well to look after her children, she says. "Since I started getting ARVs, I feel OK, and with the viral monitoring I'm so happy because I know if the drugs are working."

Nkumbi's blood is taken from a finger prick and blotted on to absorbent paper. It will be taken by motorbike to the district hospital for testing. The collection of dried blood samples is being trialled by MSF at Bvumbve. If this method proves effective, it will ease storage and transportation, as samples taken in this way do not need to be kept in a fridge. It should also ease the workload of medical staff, as tests can be taken by healthcare assistants.

Nkumbi should get the results in a week. If her VL is low or "undetectable", she can continue on her one tablet a day regime. But if levels are high, she will receive counselling for three months before a second test is taken to see if any change has occurred – sometimes lack of nutritious food or a short illness can cause a temporary blip in VL levels. If after three months high levels are still recorded, she may need to switch drugs.

"Viral load is a strike in HIV management," says Arthur Mateyu, technical supervisor for eight health centres in Thyolo. He predicts more people will be put on second-line treatment as a result of the VL rollout. "What we're seeing is a lot of clients who were supposed to be on second-line, but were still on first-line drugs. People were dying, nothing could be done because of treatment failure. But viral load testing is helping us to monitor adherence to ARVs."

Malawi is considered a success story in reducing HIV infection rates, passing the tipping point – when the number of people starting treatment exceeds the number of new infections. According to UN figures, between 2001 and 2011, the rate of new HIV infections dropped by 73%. This was helped in part by the introduction of ARVs in 2003, which have slashed death tolls from 92,400 to 45,600 over the past decade.

But, with an HIV prevalence of about 10% among people aged 15 to 49, Malawi has the ninth highest HIV rate in sub-Saharan Africa, according to UNAids estimates. And more than 40% of new infections are among 10- to 19-year-olds. The country is heavily reliant on support from international donors to fund its national HIV and Aids programmes. Any increase in the number of people on second-line treatment could exacerbate the problem.

Stigma still surrounds the condition, but things are improving, says Chiyabwa. "People are opening up and feel free to come to the clinic. This year we have had more patients collecting ARVs because patients are opening up and are free from stigma," she explains.

Establishing HIV support groups has helped. The Chidothe village support group, about three miles from the clinic, meets every Monday afternoon to talk through any concerns they have about treatment or other aspects of living with HIV.

Ennet Manda, 49, from Nanthereza village, is a member. She suspects her husband passed on HIV to her because he died of unknown causes in 2002. Discovering she was HIV-positive was a relief, she says. She recently had her VL tested and her levels came back as "undetected", which means she has a very low chance of transmission and, crucially, that the drugs are working.

Manda adds: "I never worried. I accepted it [the result]. I wasn't shocked. I was happy that I finally knew my status. I started to take drugs and I've got my life back."

REPOST: 11 new genes tied to Alzheimer's disease

Alzheimer's disease, characterized by memory loss and dementia, is a fatal progressive brain disorder which medicine cannot cure as of yet. Time.com recently reported the discovery of a connection between 11 new genes and the disease, a development that may help the search for the best treatment. Read more:

Scientists have doubled the number of genes associated with Alzheimer’s disease, giving researchers twice the number of targets for drug therapies.

The genetic bonanza, reported by an international group of researchers known as the International Genomics of Alzheimer’s Project (IGAP), emerged from a study of 74,076 patients and healthy subjects from 15 countries.

Some of the new genes–which are involved with late-onset Alzheimer’s–are tied to immune response and inflammation, while others are related to cell migration and brain pathways.

Identifying so many new genes opens the opportunity for more precise drug therapies that have the chance of being more effective in treating the cognitive decline, such as memory loss, that are the hallmark of the disease.

The researchers, who published their study in the journal Nature Genetics, plan to expand the data set to look for rare variants of the genes that may help to explain the different ways the disease can develop. That may also yield clues for better drugs as well. Currently, medications can only reduce some of the cognitive symptoms of Alzheimer’s without affecting its basic disease-causing processes.

REPOST: UK firm seeks to market world's first malaria vaccine

Malaria is a disease that has plagued Africa and various parts of the world without an effective means of prevention for decades. Now, a BBC article reports that global pharmaceutical leader GSK may have the first malaria vaccine that actually works.

The trial showed a reduction in cases by 25% in infants and 50% in older babies | Image source: BBC

British drug maker GlaxoSmithKline is seeking regulatory approval for the world's first malaria vaccine after trial data showed that it had cut the number of cases in African children.

Experts say that they are optimistic about the possibility of the world's first vaccine after the trial results.

Malaria, a mosquito-borne parasitic disease, kills hundreds of thousands of people worldwide every year.

Scientists say an effective vaccine is key to attempts to eradicate it.

The vaccine known as RTS,S was found to have almost halved the number of malaria cases in young children in the trial and to have reduced by about 25% the number of malaria cases in infants.

GlaxoSmithKline (GSK) is developing RTS,S with the non-profit Path Malaria Vaccine Initiative (MVI), supported by funding from the Bill & Melinda Gates Foundation.

"Many millions of malaria cases fill the wards of our hospitals," said Halidou Tinto, a lead investigator on the RTS,S trial from Burkina Faso.

Malaria is caused by protozoan parasites that are transmitted by the bites of mosquitoes.

"Progress is being made with bed nets and other measures, but we need more tools to battle this terrible disease."

The malaria trial was Africa's largest-ever clinical trial involving almost 15,500 children in seven countries.

The findings were presented at a medical meeting in Durban, South Africa.

"Based on these data, GSK now intends to submit, in 2014, a regulatory application to the European Medicines Agency (EMA)," GSK said in a statement.

Continue reading the main story

The company has been developing the vaccine for three decades.

The statement said that the hope now is that the Geneva-based World Health Organization (WHO) may recommend the use of the RTS,S vaccine from as early as 2015 if EMA drugs regulators back its licence application.

Testing showed that 18 months after vaccination, children aged five to 17 months had a 46% reduction in the risk of clinical malaria compared to unvaccinated contemporaries.

But in infants aged six to 12 weeks at the time of vaccination, there was only a 27% reduction in risk.

A spokeswoman for GSK told the AFP news agency that the company would file its application to the EMA under a process aimed at facilitating new drugs for poorer countries.

UK politician Lynne Featherstone, International Development Minister, said: "Malaria is not just one of the world's biggest killers of children, it also burdens health systems, hinders children's development and puts a brake on economic growth. An effective malaria vaccine would have an enormous impact on the developing world.

"We welcome the scientific progress made by this research and look forward to seeing the full results in due course."

REPOST: The Wait for the No-Hangover Beer Continues

Beer and other alcoholic beverages contain some of the most dangerous chemicals for the kidneys. Read this article to learn how these beverages can also be detrimental to other organs and metabolic processes in the body.

Whether you're watching the big game at your local bar or playing an intramural kickball game under the influence, beer and sports seem to be a natural pairing.

Even so, if you have one pint too many, you'll be writhing in pain the next day because of nausea and headaches. Is there a way to drink your beer without the fear of the morning hangover?

Ben Desbrow, inspired by the beer-sports connection, ran an experiment to see how beer affected the balance of fluids in the body. Desbrow, a researcher at Griffith Health Institute in Australia, examined whether making beer more like Gatorade and adding some electrolytes would mitigate its alcohol's tendency to dehydrate people who drink it.

"We basically manipulated the electrolyte levels of two commercial beers, one regular strength and one light beer, and gave it to research subjects who'd just lost a significant amount of sweat by exercising," Desbrow said in a statement. "We then used several measures to monitor the participant's fluid recovery to the different beers."

According to the research, published in the International Journal of Sport Nutrition and Exercise Metabolism, subjects lost about two percent of their body mass after exercising and replenished most of the fluid they lost with beer.

The light beer (with 2.3 percent alcohol by volume) fortified with sodium fared the best, helping the subjects retain about one-third more of their body's fluids and urinate less. However, the result was not statistically different than the regular light beer, which had less alcohol than regular beer.

In addition to more research being required on the dehydrating effects of beer additives, there is more to the hangover than dehydration. Michael Oshinsky, the director of preclinical research at the Jefferson Headache Center in Pennsylvania, said that one of alcohol's metabolism byproducts, acetate, plays a big role in the hangover headache.

"We reproduced the alcohol-induced headache in rats," he told ABC News. "If you block the enzyme that breaks down acetaldehyde to acetate, you don't get a headache."

There is also some human evidence for acetate playing a role in the hangover.

"In the past, about 25 percent of kidney dialysis patients said they had whopper headaches," said Oshinsky. "They changed the concentration of the acetate in the dialysis bags, and now it's less than one percent. It's not dehydration that induces the headache."

REPOST: Many Africans with Diabetes Unaware of Illness

A study published by the World Diabetes Atlas found that more than 15 million Africans are unaware that they have diabetes. It also predicted that this number will surpass 500 million by 2031. The Voice of America provides a detailed report on this issue.

YAOUNDE, CAMEROON — A study published in the World Diabetes Atlas says that more than 80 percent of people living with diabetes in sub-Saharan Africa do not know that they suffer from the disease. Sub-Saharan Africa has more than 15 million of the 371 million people living with diabetes in the world.

The report states that diabetes is a global burden as the number of people living with the disease continues to rise. But it says the situation is worse in sub-Saharan Africa.


Image source: voanews.com

Dr. Palma Mesumbe of the Cameroon Diabetes Association said even in North Africa where many more people visit hospitals, half of the patients did not know that they had diabetes.

“It is clearly established today that the number of diabetics is increasing on the day. Half of the people who have diabetes do not know they have it. We are talking about 52.9 percent for instance in North Africa that do not know that they have diabetes,” said Dr. Mesumbe.

The World Diabetes Atlas study adds that the greatest number of people with diabetes are between the ages of 40 and 59. Another medic, Dayawa Akuns, said a lot more within the same age group may be living with diabetes without knowing it, since symptoms can only be noticed at chronic stages.

“At the moment when we have the signs and symptoms of diabetes, it is assumed that more than 50 percent of the cells that have the responsibility to produce insulin have been destroyed. Over time as these cells are being destroyed, we are not going to see the symptoms because it has not reached a particular threshold to trigger signs and symptoms,” said Akuns.

It is projected that by 2031 the number of people living with the disease will increase to more than 552 million. Palma Mesumbe said that it would be a serious problem, especially in Africa which is socially and economically disadvantaged.

“It's going to be a problem in Africa where we are going to see a doubling in the prevalence of diabetes. We are at 4.3 percent and in 20 years that percentage is going to double, and the problem is how ready are we to handle that situation,” said Dr. Mesumbe.

To control the situation, the report says governments must reinforce diabetes awareness strategies and support associations fighting the disease.

Bladders are not made of steel

When you’ve got to go, you’ve got to go.

Sometimes, people feel the need to urinate at inopportune moments. The potty emergency is a staple of rather vulgar comedy and has been a recurring source of fun in The Sims and its successors, where players can enjoy the writhing misery of their digital people who can’t access toilets.

This is normal—assuming that you can hold it in until long enough for you to find a bathroom. However, this is even more inconvenient if you happen to have urinary incontinence. Having to control your bladder can be an embarrassing and unnerving experience, and it can make daily life extremely difficult. These unhappy little accidents may also lead to serious complications, such as skin and urinary tract infections, and drastic changes in your work and personal life.

Image Source: hkpr.on.ca

Dealing with urinary incontinence can be a grueling task, but it is not an impossible one. While extreme cases may require medical intervention, these are rare. Doctors would typically seek out the cause of the incontinence—which could range from certain medication doses to aging, even prostate cancer in some cases. The course of treatment for incontinence would depend on its cause, but certain lifestyle adjustments can help make the situation a lot easier if the problem recurs:

• Do not overuse douches, pads, and other control devices, and don’t wash too much. Sometimes, when it happens, it’s best to let it all dry by itself. 

• Have a bedpan or other urinating aid with you in certain parts of the day. 

• Banish any and all potential causes of temporary incontinence or take them in moderation.

REPOST: Diet and eczema: The facts

A good diet can bring about many benefits, including comfort from the itches and pains associated with eczema. According to this article from WebMD, there might have to be considerations about the age of the patient, but the approach is definitely still worth the try.

If you have eczema, you want to do all you can to try to stop the irritation and itching it can cause. So you may be eager to try eczema diets promoted in books or on the Internet.

How helpful are these eczema diets? Research about diet and eczema is conflicting.

This article will review what experts recommend when it comes to diet and eczema.

Diet and Eczema in Children

"Some young children have eczema caused by allergic reactions to certain foods," says Donald V. Belsito.

MD. Belsito is professor of clinical dermatology at Columbia University. "But after age 3 or 4, eczema caused by foods is very rare. Food can cause hives and other skin reactions, but not eczema."

If you are concerned that a food allergy is playing a role in your child’s eczema, talk with your doctor. Although you can have your child checked for food allergies, the results are often not reliable.

"Positive results [to food allergy tests] are very common, even if your child doesn’t have an allergy," says Lawrence Eichenfield, MD, chief of Pediatric Dermatology at Rady Children’s Hospital in San Diego. "So while it’s sometimes helpful for children with severe eczema, I wouldn’t recommend it for everyone."

Diet and Eczema in Adults

Although some adults report having worse eczema symptoms after eating certain foods, no studies have been able to establish a link.

"There is no science linking certain foods with flare-ups. But it can be an individual thing," says Andrea Cambio MD, FAAD. Cambio is the medical director of Cambio Dermatology in southwest Florida. "For example, if a patient reports eating chocolate makes her eczema worse, then I would advise her to cut down or eliminate chocolate from her diet." Be sure to talk to your health care provider before eliminating any food from your diet, and before going on a special diet.

Cambio cautions that it is not always easy to figure out what’s making eczema flare. "Because we are exposed to many potential triggers in a given day, it is often hard to tell. Sometimes, it may seem to the patient that certain foods are making eczema symptoms worse. But then we find that something else, like stress, is actually the culprit."

Research Into Foods That May Help Eczema

Although most foods and supplements have not shown promise in eczema research, research is ongoing.

For example, some studies suggest that probiotics may help relieve the symptoms of eczema in children. Probiotics are a type of live bacteria. They can be found in foods like yogurt and in some supplements. Most of these studies were done in other countries and tested different kinds of probiotics. So it is not clear what type of probiotics are most useful. "More research in this area is surely needed before we can make a definite recommendation," says Cambio.

Another food being studied as a benefit for eczema is tea. Although there is no definitive evidence, a few studies suggest that drinking black, green, or oolong tea may help relieve eczema symptoms. Omega-3 fatty acids found in fish and fish oil, which help fight inflammation, are also being studied for eczema.

What Should a Person With Eczema Do?

Choose a healthy diet. Scientific research has established without doubt that a healthy diet with plenty of fruits, vegetables, low-fat dairy, and whole grains is good for your overall health. "A healthy diet and lifestyle are good recommendations for anyone with a chronic condition," says Belsito.

The road to a healthy body entails caring for one’s organs, including the kidneys. Find out how important it is to care for it by asking nephrologists like Dr. Paul Frymoyer. You can also follow this Twitter page which contains more links to related articles.

REPOST: Alabama Fresenius clinic shut down after patient deaths has history of infection related citations

That clinics like this continue to operate should be a reasonable cause of concern. After all, it is the patients' safety that is at risk. More on this story in this article from Nephrologynews.com.

A Fresenius Medical Care North America dialysis center in Bessemer, Ala that was recently shut down after two dialysis patients died and others were hospitalized due to infection-related illnesses, was also cited in a report a year ago by the state health department for infection-control deficiencies that included a case where a patient was hospitalized, AL.com reports. The Bessemer Kidney Center is one of a dozen dialysis centers in Alabama owned by Fresenius Medical Care North America that have been cited for deficiencies in the past two years, according to AL.com. The majority of the citations were for deficiencies related to infection control, disinfection, hand washing and glove use.

"We are currently in the midst of an investigation with the assistance of the CDC and the Fresenius corporate professionals. When the investigation is complete, we will have a statement," a representative from Alabama Department of Public Health told NN&I.

Fresenius spokesperson Kent Jarrell said the state Department of Health and the Centers for Disease Control and Prevention were called in to investigate the incidences before the dialysis provider shut down the 36-station dialysis clinic on May 8. Jarrell said it remains unclear what the cause or type of infection the dialysis patients incurred and when the clinic would reopen.

REPOST: Foods to power up your spring

To achieve or maintain great physique, people have to learn to choose foods that are high in nutritional value but do not necessarily provide boring meal. CNN Health provides a list of foods that people may use as a guideline to achieve optimal nutrition.

There's a food movement afoot: Eating well to look, feel, and perform our very best is hot.

And as Jamie Oliver and Michelle Obama alike are showing us, this isn't a matter of choking down foods because they're good for you. It's about filling your plate with delicious fare.

"Food, if it's chosen well, can reshape our medical destinies for the better," says Dr. David Katz, director of the Yale Prevention Research Center. It can also improve our mood and focus. Here's how to graze your way to a supercharged you.

Power up: Your stamina

Artichokes. If you've been huffing and puffing up the stairs lately, try these spiky-leafed vegetables. They're loaded with magnesium, a mineral vital for more than 300 biochemical reactions in the body, including one of the most important -- generating energy, says Forrest Nielsen, a U.S. Department of Agriculture research nutritionist."If you're not getting enough magnesium, your muscles have to work harder to react and you tire more quickly."


Image source: turner.com

And about 68% of us aren't getting our proper share of this mighty mineral. For women, the goal is 320 milligrams (mg) per day. One medium artichoke gets you 77 mg of magnesium (a good deal for only 60 calories!). Other top sources include nuts, legumes, and whole grains.

Spinach. These tasty leaves are a great source of iron (especially if you don't eat meat), which is a key component in red blood cells that fuel our muscles with oxygen for energy. But researchers in Sweden recently identified another way in which these greens might keep you charged: Compounds found in spinach actually increase the efficiency of our mitochondria, the energy-producing factories inside our cells. That means eating a cup of cooked spinach a day may give you more lasting power on the elliptical machine (or in your daily sprint to catch the bus).

Power up: Your mood

Walnuts. Walnuts are packed with tryptophan, an amino acid your body needs to create the feel-great chemical serotonin. (In fact, Spanish researchers found that walnut eaters have higher levels of this natural mood-regulator.) Another perk: "They're digested slowly," Katz says. "This contributes to mood stability and can help you tolerate stress."

Asparagus. Those green spears are one of the best veggie sources of folate, a B vitamin that could help keep you out of a slump. "Folate is important for the synthesis of the neurotransmitters dopamine, serotonin, and norepinephrine," says Dr. David Mischoulon, associate professor of psychiatry at Harvard Medical School. All of these are crucial for mood.

A cup of cooked asparagus has 268 micrograms (mcg) -- two-thirds of the 400 mcg RDA for women. Add a cup of enriched pasta -- which is fortified with folic acid, the synthetic form of folate -- and you'll have a feel-good meal indeed.

Power up: Your skin

Salmon. There's wrinkle prevention on your plate: "Salmon is rich in a fatty acid called eicosapentaenoic acid (EPA), a type of omega-3 that naturally helps block the release of UV-induced enzymes that diminish collagen, causing lines and sagging skin," says Dr. Ariel Ostad, a dermatologist in New York City. Bonus: Omega-3s also regulate oil production in the skin and boost hydration, which helps keep your complexion dewy and acne-free.


Image source: turner.com

Strawberries. They may not have the smoothest complexion themselves, but strawberries can get you one. They're loaded with antioxidants that help your skin repair damage caused by environmental factors like pollution and UV rays. Plus, they're packed with vitamin C (less than a cup gets you your entire 75 mg RDA) -- the vitamin associated with fewer wrinkles and less dryness, per research in the American Journal of Clinical Nutrition.

Try them in a homemade facial, too. "Direct application of the antioxidants in strawberries -- as well as the natural exfoliant they contain, alpha-hydroxy acid -- will give you great results," Ostad says.

Power up: Your memory

Eggs. Have your over-easies before you hit the Easter egg hunt. The yolks are chock-full of choline, a key nutrient for recall. "Your body needs choline to make a brain chemical called acetylcholine, crucial for storing memories," says Dr. Steven Zeisel, director of the Nutrition Research Institute at the University of North Carolina at Chapel Hill. The recommended dietary allowance (RDA) for choline is 425 mg. There are 147 mg in a large egg; other good options are nuts and red meat.

Blueberries. Eat them regularly and you may reap big brain benefits. In one recent study, people with age-related memory decline who drank roughly two and a half cups of blueberry juice per day for 12 weeks (the equivalent of eating a cup of blueberries) made significant improvements on memory and learning tests compared with those who drank a placebo juice.

The secret component? A type of antioxidant called anthocyanins, says study co-author Robert Krikorian, professor of clinical psychiatry at the University of Cincinnati: "Anthocyanins have been shown in animal studies to increase signals among brain cells and improve their resilience, enhancing learning and memory."

Power up: Your weight loss

Spring garlic. The slim-you benefit of this seasonal treat lies in a compound called allicin, which gives garlic its pungent smell. "Allicin may keep you from overeating by stimulating satiety in the brain," says Tara Gidus, a dietitian in Orlando. Spring garlic has a milder, sweeter taste than the dried white bulbs you buy later in the season. Enjoy it diced on salad for a fat-fighting side or lunch.

Legumes. Beans are one of your best bets if you're trying to drop pounds, says Dr. Joseph Colella, a bariatric surgeon at Magee-Womens Hospital in Pittsburgh. "Your body has to work to break down the bean to get through the fiber," he explains, "so you're actually expending energy to digest it."

Even better, Colella says, the protein in legumes activates an "I'm satisfied" message in the hunger center of your brain.

REPOST: Salty Truth: Adults Worldwide Eating Too Much Sodium

Much focus has been placed on the national epidemic of obesity, but it seems adults the world round may actually be suffering from an equally pressing diet matter. This article from TIME Healthland talks about the global problem of consuming too much salt.

The latest research shows that almost everyone needs to hold the salt.

Image source: TIME

It’s a critical flavor enhancer for so many foods, and in centuries past, it was necessary for preserving perishables before the advent of refrigerators. But salt, alas, is one of the many factors plaguing American health. The American Heart Association (AHA) links too much salt in the diet to a higher risk for heart disease, hypertension and stroke, and according to research presented this week at the AHA’s 2013 Scientific Sessions, excessive salt led to nearly 2.3 million heart-related deaths worldwide in 2010.

The researchers analyzed 247 surveys of adults participating in the 2010 Global Burden of Disease Survey, which is a collaborative study involving researchers from 50 different countries. The participants reported on their sodium intake from 1990 to 2010 in food questionnaires. Overall, adults around the world ate an average of 4,000 mg of sodium a day, either from prepared foods or from table salt, soy sauce or additional salt sprinkled into meals while cooking. That’s twice the amount recommended by the World Health Organization (2,000 mg per day) and nearly three times the amount the AHA says is healthy (1,500 mg per day).

Of the 187 countries represented in the surveys, 181, home to 99% of the world’s population, exceeded the World Health Organization’s salt limit; only Kenya adhered to the AHA’s recommendation.

To emphasize the contribution that high sodium intake can have on health, the researchers then conducted a meta-analysis of 107 trials that measured the relationship between participants’ salt consumption and blood pressure and heart-disease risk.

Among people dying from heart attacks, strokes or other heart-related disorders, 40% were premature and occurred in people 69 and younger. Excessive salt intake — defined as anything above 1,000 mg per day — was linked to 84% of the deaths, and the majority occurred in low- and middle-income countries.

Out of the 30 largest countries in the world, the U.S. ranked 19th, with 429 deaths per million adults due to excessive salt consumption.

The Salt Institute criticized the study, noting that the added heart-disease risk was compared with an unrealistically low level of salt consumption that no country in the world met. “This latest AHA statistical study on the worldwide mortality from dietary salt is misleading and totally devoid of genuine evidence,” said Morton Satin, vice president of science and research for the Salt Institute, in a statement. “Using a highly flawed statistical model, researchers simply projected potential reductions in mortality without considering all known health risks resulting from low salt intake.”

Still, adults are not the only ones at risk. In other research presented at the AHA meeting, scientists reported that children are already eating too much salt as well. The high sodium content in prepackaged meals and snacks targeted at kids is pushing them to eat unhealthy amounts. About 75% of prepackaged meals are high in sodium, according to data that analyzed the salt content in 1,115 products for babies and toddlers.

In the analysis, the researchers defined “high in sodium” as containing over 210 mg per serving, and they found that some toddler meals contained up to 630 mg of sodium per serving. “Our concern is the possible long-term health risks of introducing high levels of sodium in a child’s diet, because high blood pressure, as well as a preference for salty foods, may develop early in life. The less sodium in an infant’s or toddler’s diet, the less he or she may want it when older,” said lead author Joyce Maalouf, a fellow at the National Center for Chronic Disease Prevention and Health Promotion at the Centers for Disease Control and Prevention in Atlanta, in a statement.

And the AHA says it’s worth remembering that salt doesn’t just come in the shaker on the table. Because it’s hidden in so many prepackaged and prepared foods, it’s important to read labels and nutritional information for things you don’t make yourself. And when cooking, keep salt to a minimum and try substituting with other flavors, like the sourness of lemon juice, to trick your taste buds into thinking they’re getting salt.

Salty diets eventually take their toll on other organs, including the kidneys. As a licensed nephrologist, Dr. Paul Frymoyer pays particular attention to developments in the medical field involving organ and kidney function. This website outlines more information about his work.

Are multivitamins necessary?

The concept of the balanced diet was promoted to ensure that people obtain the necessary amount of vitamins and minerals from their daily food intake. The reality is that a balanced diet is difficult to achieve, as the average adult finds himself hard-pressed to eat well amid a busy work week. Preying on the people’s fear of a weak immune system, supplement manufacturers suggest taking multivitamins– pills that promise to fulfill a person’s vitamin requirements by simply being swallowed.

One argument for the necessity of multivitamins can be summarized by the old adage, it is better to be safe than sorry Although medicine has progressed to a point where there is an available cure for virtually every common infection, parasites, bacteria, and strains of viruses still manage to evolve and spread. Vaccines are not always developed in time. With the constant threat of infection, adults are better off spending a few dollars on a bottle of vitamins than hundreds or thousands on hospital bills.

The counterargument is that, despite possibly preventing disease, multivitamins do not protect against heart attack and stroke– two considerably more pressing conditions which most adults would rather prevent. When the cost that would go to purchasing multivitamins could instead go to preventing death by heart failure, the choice is clear.

Whether or not multivitamins are necessary is completely up to the person taking them. An unhealthy lifestyle, such as one with little sleep, can cause the immune system to seek a boost. In any case, before deciding to take multivitamins, one must always first consult a doctor.

Some adults refuse to take pill vitamins because of myths about kidney damage. Licensed nephrologist Paul Frymoyer, M.D., has guidelines about eating and living for a healthy kidney provided on this website.

Kidney beans and kidney health

In the olden times, people believed that a particular body part was cured or made healthy by plants that resembled it. Years later, science has proved that this belief is not entirely baseless. Take kidney beans, for example.

The kidneys play a key part in a person’s overall well-being. Responsible for keeping the body clean and for maintaining homeostasis, they prevent people from being poisoned by their own waste. However, they may be damaged by factors like stress and practices like an imbalanced diet rich in fat and sodium.

While there are many types of food that help nurture the kidneys, special interest is given to kidney beans. True to their name, they look like human kidneys in terms of shape and color. They also contain many nutrients that can enhance kidney health. For one, they contain very low levels of fat but plenty of soluble and insoluble fiber, making them great for maintaining low blood pressure and stable blood sugar levels. Kidney beans also contain low amounts of sodium, sugar, and cholesterol, but they are an excellent source of protein, magnesium, and potassium.

Kidney beans are a great addition to a balanced diet as they help maintain healthy kidneys. Meanwhile, people with kidney disease must monitor their consumption of this legume. The protein it contains is helpful under normal circumstances, but too much of it may have adverse effects on the kidneys.

AIDS: Reduced infections in Sub-Saharan Africa but rising elsewhere

Scuttling the AIDS epidemic where it has been coasting most is probably every medical and healthcare professional’s global advocacy. Seven years ago, volunteers from Doctors Without Borders and medical doctors who have been on Sub-Saharan African missions to provide assistance to its impoverished ailing populations would have proffered a mix of panic and ruefulness in their situationers.


Currently, there are signs that interventions to curb the global AIDS pandemic are working in Sub-Saharan Africa. This area is still the most important region of concern, for it is the residence of 23.5 million global cases of HIV infection. An alarming percentage of victims are women who pass on the disease to their babies.

Seven years ago, too, the dismal toll of the yet incurable disease could have completely disheartened humanitarian movements. The slog to reduce morbidity from 1.8 million in 2005 to the now more optimistic figure of 1.2 million (2011 statistics) has taken painstaking efforts and donations from UNAIDS, non-profits, governments, CSR movements, and philanthropists. Another heave of global resources to salvage the most afflicted region in the world should be lined up for another push at the reduction of deaths and infections.


Yet, countering the silver lining in Sub-Saharan Africa is the push of AIDS to other regions of the world. Asia is alarmingly looking like the next emergency situation. Sadly, its rising toll is due not to extreme poverty but complacency in prevention. Sexual practices in the continent’s thriving sex work sector could be libertine about protection, while in some countries, contraception remains a taboo.
