The Coconut Oil Craze

October 22nd, 2014

By Danielle Grear, PharmD Student

Super-food, super-health, or super-hype? Coconut oil has been a trending topic in today’s society with its recent health claims for improving weight, fighting bacteria, treating Alzheimer’s, moisturizing skin, and the list goes on.1 Perhaps the most recent way coconut oil is being used today is in a process called “oil pulling,” which requires swishing a tablespoon of oil in the mouth for several minutes in order to detox the body and improve dental health. While the FDA has not yet approved the use of coconut oil for the treatment or prevention of disease, many consumers swear by the positive effects coconut oil has in improving their health.2

A recent article published by The Huffington Post explores the use of coconut oil pulling as a means to whiten teeth, reduce bacteria, strengthen the gums and jaw, and prevent bad breath.3 “It can be a good way to supplement recommended practices like tooth brushing, flossing, and regular dental visits,” says Michelle Hurlbutt, RDH, MSDH, an associate professor of dental hygiene at Loma Linda University in Southern California. Hurlbutt conducted a pilot study and found evidence that showed oil pulling can decrease the bacteria associated with dental cavities. Contrary to popular claims of coconut oil, however, she found that sesame oil had a 5-fold decrease in the level of Streptococcus mutans (a common bacteria associated with a high risk of cavities) compared to only a 2-fold decrease in the bacteria with coconut oil. Furthermore, after daily oil pulling stopped, the bad bacteria began to reemerge in both groups. While I believe that some may indeed have evidence supporting their experience of oil pulling’s benefits, I agree with Hurlbutt that the scientific evidence behind this process is lacking and needs further research to back these claims. The article does a good job in addressing that issue, and even states that oil pulling should not be used to replace regular oral health care.

To further investigate the use of coconut oil in oil pulling, a research study published in the Asia Journal of Public Health studied the effects of coconut oil pulling on oral microorganisms in biofilm models.4 A biofilm is a thin, slimy film of bacteria that adheres to a matrix. The bacteria that were used in this study on a saliva-coated plate were: Streptococcus Mutans, Lactobacillus Casei, and Candida Albicans, which are all predominately found in dental plaque and associated with infections. The study found that as coconut oil was exposed to the bacteria for one minute, it exhibited antimicrobial (anti-bacteria) activity on S. Mutans and C. Albicans. This allowed researchers to conclude that oil pulling therapy could be used as a preventative home therapy to maintain oral hygiene, especially in developing countries. However, while this article certainly shows the benefits of oil pulling, the study has its fair share of limitations. Predominately, because the mechanisms of oil pulling action are not known, further studies are needed to investigate the action of coconut oil on dental plaque and other microorganisms. Long-term effects in clinical trials on humans are also needed to provide significant data for its use in practice.

In addition, one of the main components of coconut oil is lauric acid. This saturated fat is a medium length fatty acid and has been shown in other studies to have an antimicrobial effect against certain bacteria (gram-positive) and yeasts.5 Even compared to other acids, lauric acid ultimately gave better results in fighting infections and inflammation.6 Because the bacteria Streptococcus mutans has been found in association with cavities3, there is a great possibility that further research can prove the benefits of lauric acid in oil pulling.

So what does this all mean? While the evidence for coconut oil in the use of oil pulling and treatment of various diseases is certainly unresolved, oil pulling has been found to have limited side effects as long as the technique is properly conducted.3 However, contrary to popular advertisements today, the articles studied showed that coconut oil is not a “means to cure all.” In fact, it should only be used as a supplement and not a way to treat serious conditions or infections. As a future pharmacist, I would inform patients inquiring about coconut oil pulling that while there have been reports of people experiencing benefits, this technique has not been fully researched and approved by the FDA. Patients must understand that while oil pulling will likely not harm them, it may not help them either. As research continues, hopefully more conclusive evidence will be produced, giving healthcare providers a better understanding of what to expect from the use of coconut oil in oil pulling.

Seeking relief when your child is coughing?

October 22nd, 2014

by Laura Farleman, PharmD candidate

Is your child’s nagging cough keeping you up at night? The honey in your kitchen may be the alternative to drug-laced syrups parents are searching for to calm their children’s coughs. The thick syrup nature of honey helps to soothe the throat and increase saliva, which can help reduce the urge to cough. Although not always severe, cough causes anxiety and disrupts sleep for parents and children. This drives many parents to seek immediate relief for their children. In recent years popular opinion has drifted toward the use of honey, but has research proven this golden nectar effective?

The current standard of care for cough in children under the age of 6 recommends talking to a doctor. In 2008, manufacturers voluntarily updated cough and cold product labels to state “do not use” in children under 4 years of age. There are few options available when treating cough in children under 4 years old without talking to a doctor. Main treatment options for children over the age of 4 have focused on cough syrups, such as Delsym or Benadryl containing dextromethorphan (DM) or diphenhydramine (DPH), respectively.1

Honey for acute cough in children, a Cochrane review published in June 2014 looked at the effectiveness of honey for cough in children compared to two commonly used cough medications. A Cochrane review is an organized review of primary research in human health care and health policy. It is recognized worldwide as the highest standard in evidence-based health care. In other words, Cochrane reviews provide the most reliable source for health care information. However, this Cochrane review is limited by only including two small studies each with high risk of bias. This review included two random-control trials involving 265 children (aged 2 to 18 years old) comparing the effect of honey to DM, DPH and ‘no treatment’ on cough relief.2 According to Honey for acute cough in children, researchers determined honey to be a better option than ‘no treatment’ and diphenhydramine (Benadryl) options. Honey was found to be equal to dextromethorphan (Delsym) for reducing frequency, severity, and impact of cough on sleep quality.2

The first study used for this review was published by Paul et al. in 2007, included 105 children (aged 2-18 years) and found honey to be a better option for treating cough than no treatment. Comparison of honey and DM did not show differences in the 2007 Paul study. 3 Compared to DM and no treatment, parents favored honey for relief of their child’s nighttime cough and sleep difficulty.3 The second study used for this review, Shadkam 2010, included 139 children (aged 2-5 years) with a cough and revealed that a 2.5-mL honey dose before sleep provided greater relief of cough compared to DM and DPH.1

A journal review by Dr. Ron Feise from 2008 about the Paul 2007 study stated that honey was better than no treatment for cough frequency, but DM was not a better treatment than ‘no treatment’.4 According to this journal review, DM used to treat childhood cough is not supported by the American Academy of Pediatrics (AAP)5 or the American College of Chest Physicians (ACCP)6. DM is associated with several adverse side effects in children, such as nausea, vomiting, constipation, and/or dizziness.7 In contrast, honey is generally recognized as safe with the exception of a severe form of food poisoning in children under the age of 1.8 Honey is not appropriate in this age group, because the bacteria in the stomach of infants (less than one year of age) has not fully developed.8 Honey provides a safe and effective option for children (1 year and older) over OTC cough and cold medications, which aren’t recommended for children younger than 6 years old.

Practically, what does this mean? The next time your child develops a cough you might consider grabbing some honey from the kitchen or local grocery store. When your child begins to develop a cough, start by giving your child (12 months or older) ½ teaspoon of honey (2.5 mL), or (if 2 years old or older) two teaspoons (10 mL) of honey. Honey may be taken/given as often as is needed to relieve coughing. The thick syrup of honey coats and soothes the back of the throat, while the sweet taste results in salivation, which thins mucus and reduces the urge to cough. Honey may also help the body fend off colds by alleviating cold symptoms and reducing the length of a cough or cold. In addition to honey, ensure your child drinks enough fluid and consider increasing your child’s intake of vitamin C.9

It is important though, to remember that coughing isn’t completely terrible. It’s the body’s way to clear mucus from the airway. If your child is otherwise healthy and sleeping relatively well, typically there is no reason to suppress a cough. If your child has a fever, prolonged or worsening cough, wheezing, or cold symptoms lasting longer than two weeks please talk to a doctor.10

Have you tried using honey for cough in the past? Did you find it effective? In the future, will you use honey to relieve coughing?

Protein Pump Inhibitors and Heart Disease Link

December 10th, 2013

By Yevgeniy Solokha, PharmD Student Cedarville University

Proton pump inhibitors (PPIs) are commonly used to prevent the symptoms and complications of gastroesophageal reflux disease (GERD).1 They work by reducing acid secretion in the stomach by inhibiting the gastric proton pump.2 With several products available over-the-counter (OTC), patients have also been able to use them for the self-treatment of heartburn and indigestion.3 Although these medications are effective, their long-term use has been associated with potentially serious health risks, including bone fractures and reduced magnesium levels in the blood.Not only that, but there has been some evidence suggesting that prolonged use of PPIs may also lead to heart disease.2

This association is the main topic of a recent study that has been published in the Circulation Journal of the American Heart Association. It has evaluated the effects of PPIs on mice and human endothelial cells using cell assays as well as blood samples collected from mice in vivo. The results show that PPIs lead to increased levels of asymmetrical dimethylarginine (ADMA) in the blood by inhibiting dimethylarginine dimethylaminohydrolase (DDAH), an enzyme that breaks it down. This, in turn, prevents nitric oxide synthase (NOS) from generating nitric oxide (NO), which decreases the ability of blood vessels to dilate.The article essentially calls for the need to perform additional studies to evaluate whether the general population using PPIs may be at risk for heart disease.2 This is the main limitation of the study because the results cannot be easily extrapolated to humans. Also, there may be other factors that can contribute to this association.

A similar relationship between ADMA elevations and cardiovascular events has also been discussed in an article published in the Annals of Medicine.It proposed essentially the same mechanism as the one mentioned in this study. Another Danish cohort study set out to investigate a relationship between the use of PPIs and clopidogrel with cardiovascular events. It concluded that, “the increased cardiovascular risk associated with PPI use independent of clopidogrel is caused by unmeasured confounders”.5 Basically, this means that there must be something else going on which has not been accounted for. The main objective of the mouse study discussed above was to try to identify a possible mechanism for this observation. Since this association seems to be fairly new, the literature largely seems to be inconclusive on the subject.

I feel like it is still too early to tell whether there truly is a valid relationship between PPI use and heart disease because there have not been any randomized-controlled trials conducted in humans yet. For this reason, I would not change my self-care recommendation for the short-term relief of persistent heartburn and indigestion because OTC PPIs are indicated for a limited duration of therapy consisting of 14 days, after which they have to be discontinued for at least four months.3 Nevertheless, I think that the results of this study may be good to just keep in mind in case we encounter patients who may be on unnecessary prolonged use of PPIs. The possible heart disease association would simply be another reason to contact their physician about discontinuation. In this regard, I believe that pharmacists are located within a unique position within the healthcare system to make sure that patient safety remains a priority.

Would this knowledge impact your self-care recommendation regarding PPIs?

Calcium Worth The Risk?

December 10th, 2013

By Jordan Long, PharmD Student Cedarville University

For years, calcium has been considered an essential nutrient to have in the daily diet. Intake of calcium is essential for many bodily functions including muscle contraction, nerve transmission, and bone remodeling.1 Some of the benefits from calcium are helping bone growth, prevent loss of bone density, and prevent osteoporosis development.2 But recent reports are questioning the actual efficacy in these different functions and if higher calcium levels could lead to adverse effects due to additional intake through supplementation.  These recent studies led the New York Times to post an article in April of 2013 stating that people should be Thinking Twice about Calcium Supplements.3 The article stated that not only is the efficacy of calcium supplementation in it’s prevention of bone fracture questionable, but calcium supplementation might be harmful. The views presented in this article are hard to believe, since calcium is a very common nutrient found in many foods found in the standard diet. However, recent literature is beginning to provide evidence to back up this view.

Studies have shown that calcium is essential for the increase of bone density in prepubescent children.4 Parents should highly encourage their kids to consume calcium in their diet to have strong bones. But the United States Preventative Risk Task Forces stated that there is currently insufficient evidence that the benefits from calcium supplementation over 1,000mg per day is worth the risk for the primary prevention of fracture in healthy, older woman. They also do not recommend taking less than 1,000mg a day of calcium supplementation, because it is not shown to decrease fracture at these low levels but increases risk of kidney stones.5 The National Institutes of Health recommends optimal calcium intake levels varying from 1,000mg to 1,300mg for anyone over the age of four, depending on age.1 Those numbers include the calcium from dietary intake and any calcium taken as a supplement. A lot of these studies are hard to compare and contrast their recommendations because of the high amount of variation in type of calcium supplementation and complementary supplementation, especially with vitamin D, which also plays an important role in the bones ability to absorb calcium.6

One of the primary concerns with calcium supplementation is that the risks of all cause mortality, attributed mostly to cardiovascular disease. A study observing all cause and cardiovascular mortality due to calcium found that there was an associated increase in all cause, cardiovascular, and ischemic heart disease mortality with people with an average intake of calcium above 1,400mg a day, but these results were not conclusive.7 A few other articles looking at the association of calcium and cardiovascular disease mortality found no hard evidence and said that no causality could be confirmed.8,9 Sadly, a limitation to the research of calcium effects is that randomized clinical trials might be unfeasible. The risks of high supplementation of calcium are to high and could be considered unethical to test for. But is the intake of calcium the issue? The National Institutes of Health states that calcium intake is not involved in the prevalence of cardiovascular issues, but the serum concentrations of calcium.1 Calcium serum concentrations are highly regulated by the body to obtain proper homeostatic balance, using the bones as a reservoir for excess calcium.10 But this balance could be thrown off by increased or decreased calcium intake over longer periods of time.  Even though there is some evidence that calcium supplementation could be reducing incidence of fractures, evidence is increasing regarding the incidence of cardiovascular issues.11

From the research, I would say that patients should be cautioned when thinking about taking a calcium supplement for an extended period of time. The New York Times pointed out some good points, people should try to stay away from supplements as much as possible.3 If someone is below his or her recommended daily value of calcium, higher intake of high-calcium food should be recommended. Some examples of foods that are high in calcium are milk, cheese, yogurt, kale, and spinach.1 The major thing causing problems in people that are taking calcium supplements is that they most likely have an adequate amount of calcium in there normal diet, and the additional supplement is putting them over the recommended daily amount. The supplements themselves might not be necessarily directly causing the higher risk of cardiovascular disease, but it is increasing the calcium levels above the recommended daily amount. People wanting to take calcium supplements should consult their local pharmacist or primary care provider to make sure it is appropriate. For another great resource, check out Dr. Mercola’s article on the relationship between vitamin K2, vitamin D, and calcium (Link found in references section below). It explains the proper balance of these dietary supplements and how to control your calcium levels through them.12

With all of these risks, do you know what your daily calcium intake is? Maybe it’s time you checked for yourself.

Is Aspirin a Viable Option for the Prevention of Dementia?

December 7th, 2013

by Nick Daniels, PharmD student

Dementia is one of the most prevalent health issues facing the elderly today. The disease state is characterized as a decline in memory or thinking skills severe enough to reduce a person’s ability to perform everyday activities.1 It is heavily correlated with Alzheimer’s in that 60 to 80% of those affected by the disease also suffer from dementia.1 One study estimates that 13.9%, which accounts for roughly 3.4 million people, of the population in the United States who are 71 years of age or older are affected by the disease with numbers increasing steadily as they progressed in age, with it ultimately effecting over 37% of the population older than 90.2 The severity of the symptoms associated with dementia, and its prevalence among the elderly, makes it a critical problem for which a preventative solution must be found.

The article, “Aspirin may Prevent Dementia and Cancers, World’s Largest Study Shows” published by ABC News discusses how researchers working in Australia are trying to do just that. The study, involving the participation of over 15,000 healthy Americans and Australians aged over 70, is using aspirin as a preventative agent to stop the development of the disease state through a suppression of stroke incidence.3 Researchers involved with the ASPREE study are using the aspirin in this case in an effort to keep constant the flow of blood to all areas in the brain in hopes of preventing tissue necrosis, microinfarcts, caused by ischaemic stroke.3 Tissue necrosis in the brain would result in reduced ability to think thereby causing advancement in dementia.3 Researchers began this double blind clinical trial in January of 2010 and they are expecting a reliable primary outcome measure by August of 2016.4 This sample is expected to be the most large scale available in regards to measuring aspirin preventative outcomes for dementia.5

While the aforementioned study into this area seems promising given the proven cardiovascular benefits of moderate aspirin usage and the study’s statistical power provided by its large sample size, I would advise caution to patients looking to dive headfirst into this type of preventative plan thinking it will be the guaranteed answer to solving the problem of dementia. To this point there is just not enough of a sample base to prove that the benefits of aspirin usage for the prevention of stroke outweigh the negatives, such as stomach bleeding and increased risk of massive stroke due to advanced movement of blood through the brain, associated with the medication.6 Hopefully the study currently being conducted can bring to light the answers to some of these questions. To this point, being so early on in the study, only the initial speculation by the researchers is available.

Without further evidence that validates the effectiveness of aspirin use in the prevention of dementia I cannot recommend its use for this indication. A previous study done by the NHMRC Psychiatric Epidemiology Research Centre in Australia tracking aspirin’s potential in use for preventing dementia actually found no difference between control and study groups.In cross-sectional data obtained in the study, those who had been taking NSAIDs or aspirin performed no better on the cognitive tests after account had been taken of other confounding variables.7

There are a few reasons behind the questionable results of some of these studies. The most important is they fail to acknowledge that stroke related dementia is only a portion of the larger problem of dementia as a whole.1 As was mentioned previously, up to 80% of all cases of dementia can be related to the development of Alzheimer’s which is different than the microinfarct dementia addressed by these studies.1 Many articles, like the one published by ABC, have the potential to heavily exaggerate the applicability of research being done. This could serve to mislead the public into adopting preventative strategies that could be ineffective, and at worst detrimental to their health. Also, the sample size in the NHMRC study is much smaller which could affect its validity in comparison to the larger study currently being conducted. Results from the larger study should give a more accurate representation of the medication’s effectiveness. I feel the ASPREE study also limits itself through a constrained diversity of ages. It would be more advantageous to begin the study using individuals who were much younger than 70 in order to reasonably ensure that patients had not already experienced some of the symptoms of dementia onset.

As health care professionals it is important to spread awareness in regards to dementia and the potential benefits, or shortcomings, of various preventative measures. Do you believe the limited base of evidence available for aspirin usage in the prevention of dementia is enough to warrant its use for this indication? What future do you believe the medication has in the prevention, or treatment, of neurodegenerative diseases?

Are you “Pro” Probiotic Supplements?

December 5th, 2013

by Heather Evankow, PharmD student

In recent years, the popularity of probiotic supplements has risen. Probiotics are bacteria that help maintain the natural balance of organisms (microflora) in the intestine.1 The idea of probiotics is not a new concept. The idea was first developed around 1900 by the Nobel Prize-winning recipient Elie Metchnikoff. Metchnikoff theorized that the fermented milk products Bulgarian citizens ingested were a major factor in their longer life spans when compared with other countries.2 It was not until the year 1989 when R. Fuller popularized the term “probiotics”.3 Today, probiotics can be seen in the news claiming to improve the immune system, aid in skin health, defend against depression, clear up a bloated gut, prevent urinary tract infections, and even delay allergies.4

The Daily Herald recently released the article, Probiotics are all the rage, and experts say there are results behind the hype. The author, Gabriella Boston, Boston combines the opinions of several healthcare professionals to emphasize the health benefits behind the evolving topic of probiotics.

The first healthcare provider, Megan McCusker, is a dermatologist who believes probiotics are an important treatment therapy for treatment of anything from acne to psoriasis.4 While the Federal Drug Administration (FDA) does not approve any health claims for this supplement, McCusker could recommend 5-20 billion units per day depending on the patient’s needs. There were no clinical research references to show how McCusker developed these recommendations.

A nutritionist Boston featured, Jared Rice, also believes in the benefits of probiotics. Rice has not observed any downsides with his patients taking probiotics, but still advises patients to seek medical attention before taking high doses. Rice believes it is essential to buy the healthiest probiotic supplement. Also, he believes it is important to create a probiotic-friendly body by eating whole grains, bananas, and onions while steering clear of nondigestible carbohydrates.4 Unfortunately, there was no data referenced to confirm the benefits of Rice’s claims.

Ebeth Johnson, a nutritionist and chef, also gave her expert advice for this article. She believes this probiotic trend is here to stay. She encourages incorporating probiotics into your diet by consuming unpasteurized miso, live cultured pickles, tempeh, unsweetened kefir and yogurt, and kombucha teas.5 It is unclear how Johnson came up with these supplement sources. In addition, she also did not mention any specific research to validate the quality of these sources.

While the experts in Boston’s article seem confident in their recommendations of probiotics supplements, the clinical research is still limited for probiotics. The varieties of strains make it problematic in understanding the health benefits.

One of the most researched probiotic strains is Lactobacillus rhamnosus GG (LGG). LGG has been proven to help pediatric patients with pain-related gastrointestinal (GI) disorders in many clinical studies.5 In a 2011 meta-analysis, researchers systematically searched for randomized controlled trials assessing LGG supplementations in children with functional dyspepsia (FD), irritable bowel syndrome (IBS), abdominal migraine and functional abdominal pain (FAP).5 The major limitations for this analysis included incomplete outcome data and the number of trials with a small sample size. The results revealed a decrease in severity in pain with the overall study population and the IBS subgroup.5 The frequency was also decreased in the IBS subgroup.

Another hopeful probiotic strain is Streptococcus thermophilus VSL #3. A multicenter, randomized, placebo-controlled, double-blind, crossover study has shown VSL #3 to be successful and safe in helping the lives of children with IBS.6  59 patients from ages 4-18 years of age completed the study with no untoward adverse effects reported. Researchers found no significant difference was found in the stool pattern of patients, but abdominal pain, abdominal bloating, and family life disruption were all significantly more effective to the placebo.6

Over the Counter Probiotics May Be Able to Sooth Baby’s Colic

December 5th, 2013

by Mallory Martin, PharmD student

This article posted by the BBC, “Probiotics ‘soothe some babies with colic’”,1 explores an option into easing or possibly preventing your baby’s colic. The article describes an analysis of 12 studies looking into probiotics as a treatment for colic. The analysis was done by a team of scientists in Australia and reported in the Jama Pediatrics Journal. However the article didn’t cite where in the journal this article was found. This seemed uncharacteristic and it made it difficult to evaluate their findings. All this aside, their findings were quite exciting because although colic is not a harmful condition to babies and resolves itself after 3-4 months1, it can be quite stressful for caretakers. An option for soothing baby’s colic would be highly valued for this reason.

When attempting to sooth colic, parents can be scared away by ambiguity, not wanting to give something to their baby unless it is proven. “Research shows” is a phrase that may be thrown around a lot, but what people really want to know is whether a treatment is safe for their child and if it is effective. Taking these people into consideration and with the incomplete citation by the BBC article, I wanted to explore several articles published on this topic in an attempt to come to a conclusion on whether or not to recommend probiotics for colic.

Probiotics must first be understood on their own before exploring them as a treatment for colic. Probiotics are a mixture of different microorganisms that when orally ingested are considered to have several overall health benefits.1 The word itself means “promoting life”.2 They generally have very low risk in normal adults because the cultures so closely resemblethe natural flora of the gut. 3 Probiotics are also naturally present in food. Some foods that contain probiotics are fermented vegetable such as sour kraut and most commonly yogurt.2 Probiotics contain many different types of bacteria but among the most common is Lactobacillus reuteri. It is this strain of bacteria that is considered to have the most health benefits. 2

Certain health benefits have been discovered with probiotic use. Probiotics, L. reuteri specifically, has been shown to lower LDL levels, kill bacteria that causes tooth decay, lessen the harmful effects of gingivitis, and lower your likelihood of developing episodic diarrhea or traveler’s diarrhea. Some reports even show that this bacterium can lessen a child’s risk of developing eczema through probiotic-filled breast milk. Studies in women’s health showed that it may help balance the bacteria present in the vagina and lower the risk of yeast infections, bacterial vaginosis, and urinary tract infections. Some additional benefits include its ability to reduce upper respiratory infections when compared to placebo, provide relief to baby’s colic, and reduce bloating and gas.2

Although the results are promising, research in this area is not concrete. Probiotics may have both risks and benefits for different people. Risk for special populations, such as small children and older adults, is unclear since there is little to no research done on these groups.2 So far, healthy, full-term babies who have received high doses of probiotics have not presented with any negative effects.4 However there is some evidence that young children who are pre-term or not fully healthy, such as children with weakened immune systems, catheters or other medical devices inside them, may be at risk if taking probiotics.4 When considering L. reuteri in treatment of colic, one study by Savino concluded that it is inconclusive whether L. reuteri reduces colic but it appears to reduce levels of harmful E. coli. 5,6 Savino performed a follow up study after comparing L.reuteri with simethicone and compared the bacteria against a placebo in treatment of colic.7 This study had a better study design for its desired outcome because the infants involved were chosen based on Wessel’s Criteria, a more systematic approach than the first study. The results concluded that L. reuteri DSM 17 938 at a dose of 108 colony-forming units per day in early breastfed infants improved symptoms of baby’s colic and was well tolerated and safe.7 Some factors that could contribute to the varying results in these studies include the differences in the care the infants received in different homes and different study designs. An article put out by Fox News article reported on this as well. The conclusion was that probiotics may not be effective. However in young infants, they can potentially reduce risk of asthma and eczema.4 This positive effect, while unrelated, is something to consider when evaluating probiotics for your child.

Considering all this information, I would recommend probiotics as a means of treatment for infantile colic. The best option would be for a nursing mother to start a regimen of daily probiotics and allow the probiotics to transfer through the breast milk. However, L. reuteri is available for infants to ingest. Gerber has a colic relief drop that specifically has L. reuteri in it which includes sunflower oil. Gerber also has a powder for formula around 30 dollars for 24 ounces. BioGaia has a straight L. reuteri drop for around 20 dollars for 5 mLs. There are options. Even if it may not be 100% guaranteed to be effective, if your colicky baby is becoming too much to handle and you have tried many other options, I would say it is worth a try. Especially considering no bad effects have been found and several unrelated positive effects have been suggested. Probiotics would be a safe and natural way to go in your attempt to soothe your baby and get a good night’s rest yourself. Some may not agree with me. With the lack of research and uncertainty, risks could exist. Just because no negative effects have been found does not mean that it is completely safe. Would you take that risk with your own child?

Evidence for Supplement Use to Prevent Cancer or Cardiovascular Disease?

December 4th, 2013

By Tirhas Mekonnen, PharmD Student, Cedarville University

Dietary supplements have been used for various reasons. Dietary supplements such as ascorbate, vitamin E, and ß-carotene, are reducing agents and thereby, detoxify reactive oxygen intermediates in the laboratory.1 Researchers are studying to find out if consumption of food rich in these antioxidant compounds could potentially reduce the risk for certain types of cancers as well as other chronic health problems like cardiovascular disease.  However, clinical trials with antioxidants as dietary supplements have failed to show clear beneficial effects.1

This article on Medpage Today by Todd Neale discussed a systematic review that investigated the use of mineral and dietary supplementation for primary prevention of cardiovascular disease or cancer.2 The review evaluates 24 randomized, controlled trials and 2 cohort studies that examined the benefits and harms of using vitamin and mineral supplements for primary prevention of CVD, cancer, or all-cause mortality in healthy individuals without known nutritional deficiencies.3 The study found that except for two clinical trials, there was only “a small borderline-significant benefit” from multivitamin supplements on cancer (but only in men), limited evidence supports any benefit from vitamin and mineral supplementation for the prevention of cancer or cardiovascular disease”.3 Although the review looked at many studies there are some limitations.

One of the limitations is that the review included short term studies that analyze the use of dietary supplements.3 However, those short-term studies may not confirm or indicate the outcomes of chronic use of dietary supplements. For example, the median follow up time of the study titled, “Randomized, placebo-controlled trial of the health effects of antioxidant vitamins and minerals” was only for seven and half years.4 The review also consists of studies done in various countries. However, poor eating habits, tobacco use, consumption of alcohol, and many other variables may differ from one country to the other country.  These variables are risk factors for chronic heart disease or cancer.

Other sources have also not found consistent evidence to recommend minerals and dietary supplements for the primary prevention of cardiovascular disease and cancer.  An article titled “Nutrient supplements and cardiovascular disease” discussed associations between carotenoids, folic acid, and vitamin E with CVD risk.5 As the article illustrated, previous researchers thought that vitamin E, due to its antioxidant effect, may reduce CVD. However, the article also noted more recent randomized placebo-controlled interventional trials do not support the original assumption regarding vitamin E.5 The article also pointed out that “With few exceptions, a large series of primary and secondary prevention trials have reported no significant benefit of moderate-to high-dose vitamin E supplementation of cardiovascular outcomes”.5

In addition, the use of dietary supplement folate and its association with cardiovascular health benefit was discussed in another review article by Ulrich and Potter et al. This article also is consistent with the previous reviews and studies mentioned above. “The prevention of cardiovascular disease was assumed to be another health benefit of increased folate intake; unfortunately, the results from randomized controlled trials with actual disease outcomes provide no evidence for such an effect.”6 Therefore, there is currently a lack of evidence to suggest that folate prevents cardiovascular disease or cancer.

In conclusion, after reading these reviews and studies, I agree with Mr. Todd Neale, that there is no clear answer for the following question: Is there clear evidence to recommend minerals and dietary supplements for the primary prevention of cardiovascular disease?  I would like to get your professional opinion on this matter. Please participate if you have found studies that do have a better explanation as to whether to recommend or to not recommend dietary supplements for the primary prevention of cardiovascular disease or cancer.

Are e-cigarettes a good option for smoking cessation?

December 2nd, 2013

by Tiffany Zehel, PharmD student

In 2011, an estimated 43.8 million U.S. adults were current cigarette smokers,[i] and currently, estimates of over one billion people worldwide are smokers.[ii] Cigarette smoking is a global epidemic that can give rise to several serious diseases with nearly 6 million deaths annually.[iii] The risk of serious diseases is significantly reduced after one quits smoking and maintains life-long abstinence. Unfortunately many nicotine replacement therapies (NRT’s), such as the patch or gum, have a low efficacy rate in real life practice.[iv] Many studies evaluating the use of nicotine replacement therapies find that while traditional NRT’s provided the chemical need for the individual, the behavioral and psychological needs of the individual were not being met.[v],[vi],[vii]

 The electronic cigarette (e-cigarette) was introduced to the U.S. market in 2007 to provide smokers with more freedom to smoke as well as a safer alternative compared to tobacco cigarettes.[viii] The standard e-cigarette is a battery powered electronic nicotine delivery device (ENDD) that resembles a cigarette, and delivers nicotine in a vaporized solution. The acceptance of the e-cigarette is attributed to the similarities of smoking, including the hand-to-mouth repetitive motion and the visual cue of the vapor, addressing the psychological and behavioral aspects of the addiction.[ix]

According to an article published in The Lancet, E-cigarettes were not shown to have a statistically significant difference in individuals that quit. However, they significantly reduced the amount of traditional cigarettes an individual used in a given day compared to the patch.[x] In this news article e-cigarettes are celebrated based on the fact that they show promise to eliminate tobacco smoking completely in the future, but not so much for the promise of helping people break their addiction. Smoking tobacco is very harmful and traditional cigarettes contain toxins that are carcinogenic. In that respect, e-cigarettes should be admired for their ability to replace cigarettes. The issue is that e-cigarettes are not regulated by the FDA like other NRT’s, and their safety has not been extensively researched, due to the recent emergence of the product.

The article also had several limitations. First, the study was underpowered, meaning any effect could have gone undetected, so the results may not be reliable. Another limitation is that there was a high drop out rate in the group given the nicotine patch; this is speculated to be due to the participants wanting to try e-cigarettes but instead where randomly assigned to receive the patch. A third limitation is that the e-cigarette, that this particular study group used, contained less than optimal amounts of nicotine and delivered nicotine inefficiently. As technology advances and e-cigarettes become more efficient in nicotine delivery, e-cigarettes may be proven more effective. The final limitation is that this study was over six months while the amount of time to quit cigarettes can be much longer depending on the individual.x The short amount of time also provided little ability to evaluate adverse effects that the e-cigarette may cause. Due to these obstacles, it is difficult to say whether e-cigarettes would or would not be better than the nicotine patch.

In an article published in the journal of Addiction Science and Clinical Practice (ASCP), a group of people that regularly used e-cigarettes were followed through a forum and interviewed regularly. One repetitive theme in the article was that the subjects, who identified themselves as “vapers,” drew a line between smoking cessation and nicotine cessation. They claimed that they wished to stop smoking because of the health ramifications, but because of the convenience and perceived safety of the e-cigarettes, they had no desire to quit their nicotine addiction.[xi] Up to this point, smoking cessation and nicotine cessation went hand-in-hand. NRT’s were prescribed to step the patient down from their nicotine addiction; currently e-cigarettes are not set up in this way. So now that we have this unique delivery system on our hands, we need to decide if nicotine cessation is as important as smoking cessation. We also need to do further studies on the long-term effects of e-cigarettes to evaluate their benefits over the alternative.

I do not think that replacing one addiction with a modified version of it is the best idea. While it does reduce the health risk, it does not solve the issue of nicotine addiction, the possible long-term effects, and the cost of feeding the addiction. However, I think that e-cigarettes can be beneficial for smoking cessation and nicotine cessation with proper monitoring from healthcare professionals and social support.

 Do you think that smoking cessation is more important than nicotine cessation? Do you think e-cigarettes should be utilized for nicotine-cessation?

Herbal Supplements: The Whole Truth

December 2nd, 2013

by Olumami Amaye, PharmD student

Herbal supplements come in all forms. They may be taken internally as pills or powders, dissolved into tinctures or syrups, or brewed in teas. Ointments, shampoos, or poultices may be applied to the skin, scalp, or mucous membranes. What puzzles me, however,  are the unlisted ingredients in the supplements. In fact, an article published by Live-Science on October 11th, 2013 discusses a new study which found that herbal supplements contain unlisted ingredients and may pose a health hazard to consumers.1

In the United States, herbal and other dietary supplements are regulated by the U.S. Food and Drug Administration (FDA) as foods. This means that they do not have to meet the same standards as drugs and over-the-counter medications for proof of safety, effectiveness, and what the FDA calls Good Manufacturing Practices. The active ingredient(s) in many herbs and herbal supplements are not known. There may be dozens, even hundreds, of such compounds in an herbal supplement. In 2011, some researchers conducted a study to verify the contents of 5 known herbal products: St John’s wort, Asian ginseng, echinacea, garlic and ginkgo.2  What they found was so alarming that it forced the European Union (EU) to change some legislation on herbal supplement products.3 Some herbal supplements have been found to be contaminated with metals, unlabeled prescription drugs, microorganisms, or other substances, the researchers said.3

However, in a recent article in the Archives of Internal Medicine, DM Marcus and AP Grollman stated that “Even when the Food and Drug Administration (FDA)” identifies an unsafe product, it lacks authority to mandate its removal from the market because it must meet the very high legal requirement to demonstrate a ‘significant or unreasonable’ risk.3 According to the article published by Live-Science on October 11th, 2013 BMC medicine studied a very new technique “ called DNA  barcoding test” where they analyzed 12 companies herbal products. However, out of the 12 companies that manufacture herbal supplements only 2 products were found to have no substitution, contaminants or fillers.4 The Newmaster et al. study also found that one product labeled as St.John’s wort was substituted with senna alexandrina. It contained only senna barcodes and no St. John’s wort barcoding.1  From my understanding of senna, it’s a stimulant laxative agent which if not properly used can cause  adverse effects such as diarrhea, abdominal pain, skin disorders and blistering.5 Several herbal products contained Parthenium hysterophorus (feverfew), which can cause swelling and numbness in the mouth, oral ulcers and nausea. It also reacts with medications metabolized by the liver and may increase the risk of bleeding, especially if taken with blood-thinning medications, the researchers said.1

The findings of the study are also consistent with earlier studies. For examples, one study shows   51 (75%) of 68 products contained none of the key safety messages, while other studies also share similar results.6   In light of these and other studies conducted in North American and European countries, I believe there should be some regulations in place for testing and approval of herbal products.  Personally, after reading this article I felt that using supplements can be dangerous to a person’s health. I would be very cautious before putting one of these into my body for any reason. I have learned that the improper use of supplements might lead to some health issues.

The limitations to this study are the use of new DNA barcoding methods, lack of barcode library, and not listing the names of herbal supplement manufacturers. The DNA barcoding is not generally accepted by herbal product manufacturers and no set standards are in place for industries to follow. The study also failed to list the herbal products that were tested and the brands or companies that are following unethical activities and false advertising. By not listing the companies involve, the study might mislead other consumers to think that all herbal supplements are totally bad.
