Final internship day


Us with Cecile, one of the F1 students that came to App in the fall.
Yesterday was our final day of the internship, and I have to say that it was extremely bittersweet. As excited as we were to return to Cape Town before heading back to the US, we all realize that Bloem has taken a special place in our hearts.

Anyway...back to the internship. During my last day,  I was working in the clinic helping to hand out supplements based on BMI and illness. There are three things worth noting from that experience.

Milk Mountain
1. One women came in with a small child. We asked her if she was receiving grant money for that child and when she responded that she wasn't, we asked her why not. Her response went a little something like this...the government grant agency refused to give her grant money for the child because her (the woman we were speaking to) fingerprints did not match her mothers. Umm....hello?! EVERYONE'S FINGERPRINTS ARE DIFFERENT!!! Basically, when it came down to it, the government just didn't feel like helping her and she was educated enough to know the difference.
2. The government has decided to stop funding milk supplements for mothers who have children under the age of 6 months because they are strongly trying to promote breastfeeding. Well, someone didn't get the memo and thus developed "Milk Mountain," a pile of unused milk supplements that will not ever be used and is just sitting....waiting for expiration.
3. The incidence of strokes is increasing among younger generations due to the HIV/AIDS crisis.

Sylvia Escott-Stump CNE Workshop

Today we were given the opportunity to attend a workshop/symposium led by Sylvia Escott-Stump, the former (as of June 1, 2012) president of the American Academy of Nutrition and Dietetics.

The 4th year dietetics students, the Americans, Sylvia, and one of the other speakers, Bea.

The symposium featured seven separate lectures given by four different lecturers. The lecturers included:

1. Sylvia Escott-Stump. Mrs. Escott-Stump has directed the dietetic internship and didactic program at Eastern Carolina University since 1998. She is the author of seven editions of Nutrition and Diagnosis-Related Care (Lippincott Williams & Wilkins, forthcoming 2011) and five editions of Krause's Food and Nutrition Therapy (Elsevier 2011).
2. Prof. Beatriz Dykes. She is the president of her own company, an adjunct professor at Lehman College and Hunter College, the University of New York, and had established the Department of Dietetics and Nutritional Management at Sinclair Community College in Dayton, Ohio.
3. Prof. Corinna Walsh. Prof. Walsh is an associate professor in the Department of Nutrition and Dietetics at the University of the Free State, where she teaches community and clinical nutrition.
4. Prof. Edelweiss Wentzel-Viljoen. She has extensive expertise in nutrition research, dietary methodology, food composition date, curriculum development, continuing professional development for health professional, leadership development, project management, and monitoring and evaluation.




Luckily, we received a VERY nice manual which contains all of the slide handouts, research articles, and sponsor information so that we could take additional notes and keep them for future referencing.

Lecture #1: Sylvia Escott-Stump--Better Bones: Osteoporosis Prevention
Session Objectives:

  • Participants will be able to identify at the key nutrients that support bone health
  • participants will be able to describe specific nutritional measures to prevent fractures in vulnerable populations
  • Participants will be able to teach at least four physical activities that are beneficial for preventing osteoporotic fractures
Bottom Line:
Support your bones. They support you!

Lecture #2: Prof. Edelweiss Wentzel-Viljoen: Nutrient Profiling--The South African Perspective
I didn't quite understand this lecture...and there were a lot of technical difficulties...but the conclusion was this: 
  • The prevention of non-communicable disease, in line with the WHO Strategy for the Prevention of Non-Communicable Disease, underpins the suggested Nutrient Profile Model (NPM). Nutrient Profiling is intended to be used as a screening tool to determine whether foods could be eligible to carry any form of health claim or not. There are existing regulations for application for claims;
  • The scientific basis suggested that there is no reason to tweak the NPM to be applicable to the South African environment;
  • The stakeholders support the use of the NPM
Lecture #3: Prof. Corinna Walsh: Evidence Based Practice
Steps in the Evidence Based Practice (EBP) Process:
  1. Assess the patient
  2. Ask the questions
  3. Acquire the evidence
  4. Appraise the evidence
  5. Apply the evidence
The PICO concept (used to focus questions):
P--patient or problem
I--intervention, prognostic factor or exposure
C--comparison
O--outcomes

Conclusion:
  • EBP develops guidelines of best practice to inform decisions about patient care
  • A reliance on "the way it was always done" can be contradicted by new and better information
  • When empirical research foundations are combined with the experience of the health professional and on family values (preferences of the patient), best practice for the individual can be assured
Lecture #4: Prof. Beatriz Dykes--Management in Dietetics Practice & Strategies in Dealing with Stress (Managing the Good, the Bad, and the Ugly)
Learning Objectives: 
  • List various practice settings for the dietetic professionals
  • Describe the various styles of management and relate them to own practices
  • List strategies to deal with stress
Strategies for success: 
  • Anticipate
  • Think Critically
  • Interpret
  • Decide
  • Align
Lecture #5: Sylvia Escott-Stump--Nutritional Genetics: Discovering New Practice Horizons
Lecture Objectives: 
  • Describe the role of nutrition in genetics
  • Identify key nutrients affecting gene expression or suppression (folic acid, vitamin B-12, vitamin D)
  • Describe new employment opportunities for dietitians
This was definitely the most interesting and thought provoking lecture. Certainly a new field of study for this discipline. 

Lecture #6: Prof. Beatriz Dykes--Leadership Challenge in Clinical Dietetics
Objectives: 
  • Discuss the types of leadership and determine which are appropriate in various clinical settings
  • Focus on leadership training needed in the practice of dietetics
Conclusion:
  • Clinical dietitians and nutrition professionals need to anticipate and prepare for changes today and in the future. The status quo in no longer appropriate or sufficient to meet today's challenges. 
  • The 21st century dietetic practitioners will continue to see changes in information technology, the demographic composition of the world, personal lifestyle, and health care delivery systems. 
Lecture #7: Sylvia Escott-Stump--GI Medley: Prebiotics, Probiotics, and Synbiotics
Lecture Objectives: 
  • Identify food sources of prebiotics and probiotics
  • Describe uses of probiotics and prebiotics
  • Identify potential risks
Goal....HEALTHY, HAPPY GUTS! 

One day...this country will know my real name! 

So, as you can see, today was full of information and new knowledge! We had the opportunity to talk to Mrs. Escott-Stump personally and I think that we really able to learn a lot from her. Tomorrow is that last day of the internship...and it's most certainly bitter-sweet. Bloem has definitely taken a place in my heart and it is hard to leave it behind.

MUCPP Day 2

Today, unfortunately, I was unable to attend the usual Tuesday interdisciplinary team meeting because the doctor and his students that are normally in attendance are already on vacation. So instead, Mrs. Kruger (our fearless MUCPP leader) gave me a lesson on the ins and outs of the program and a tour of the mobile health unit of sorts.

The Mangaung-University of the Free State Community Partnership Program (MUCPP) was established in 1991 as part of a grant funded by a US company, the Kellogg Foundation. Kellogg invited all universities in South Africa to present proposals in which they partnered with the community, and the University of the Free State won. The aim of MUCPP is to learn for students and faculty to learn from each other and to assist one another.

The MUCPP is based off of the needs of the Community of Mangaung. Those included poverty and disempowerment, basic needs (housing, roads, water, sewage disposal, and electricity), recreational facilities, social services (for women, children, and the elderly), social problems (teenage pregnancies and substance abuse), lack of (early) learning opportunities and school readiness, adult illiteracy, and the unavailability and inaccessibility of medical services and the insensitivity of health care personnel. Today, student for the disciplines of health, economic, agricultural, construction, education/training, sport/recreation, youth/culture, and administration studies all help to make the goal of the MUCPP possible.

The dieticians of the MUCPP go out in to the community in the hopes of lowering the rates of HIV, TB, and malnutrition among the population of the townships. Normally, they will go out in their mobile health unit, but due to the faulty breaks, we won't be using it this week.

Since the unit is broken this week, you can enjoy Ryland's photo with our "security guard" and the van!
The unit houses a slew of brochures and pamphlets in at least four different languages explaining how nutrition can determine the course of a disease such as HIV, TB, or diabetes. The health care workers will take these brochures to the households and leave them for the family members to remind them that what they eat can play a large role in how they feel. 

Mrs. Kruger gave me an outline of the nutritional supplementation policy and a breakdown of some of the different supplements that they prescribe to the community members and when it is appropriate to prescribe them. She also explained the coding for indication of HIV status within health care charts. It's quite complicated and I can't imagine having to use it on a daily basis. However, on the newer birth charts, the HIV status of the mother and baby can be clearly stated without any of the cryptic coding previously used.

The biggest thing that she explained to me was the community survey that they use when they talk to the households. It goes a little something like this:

  • The date of the interview, name and address of the client are recorded\
  • The composition of the household is taken (how many people living in the house and their ages)
  • Weight and height status of adults or children that may appear malnourished
  • The head of household, the sole provider of money, and how many people contribute to household income are recorded
  • Main type of income (grant, full time job, part time job)
  • Inquiry about water access and consumption
  • Inquiry about the use of a vegetable garden (the dieticians will hand out vegetable seeds for the people in the townships to create their own vegetable gardens)
  • Inquiry about family members and disease/illness status
  • Inquiry about the frequency in which the baby/children and adults visit the community health clinic
  • Inquiry about the use of family planning, drugs, and alcohol
  • Diet history
  • Counseling dependent on what has been learned through the interview
I saw a couple of these conducted yesterday, but they were all done in Sotho, so I didn't really understand what exactly was going on. 

Tomorrow we are attending a special lecture that the department suggested we go to, so I will not be doing anything MUCPP related...but it will be back to the grind on Thursday!

MUCPP Day 1


Today, I started my last week of the internship and it was definitely a culture shock. We spent the morning in the townships around Bloemfontein going from door to door doing malnutrition and diet history screenings. It is absolutely breath taking and eye opening to see how these people live. It definitely made me appreciate the life that I live and the country that I come from that much more. Tomorrow I'm learning a little more about what exactly they do while there in the townships, but unfortunately, I won't have the same experiences as the other girls during their time at the MUCCP. This Wednesday we are attending a special lecture and so I will not be given the opportunity to actually work in the clinic and on Thursday, the woman in charge is retiring so there was talk today about going to get a celebratory coffee and cake instead of going through the townships. 

Unfortunately, it was raining outside, so I couldn't get a very good picture of the township. But here's a general idea. 

Townships begin as part of the government's RDP (relief and development program...I think). What happens is once a squatters camp (hundreds on "houses" made from scrap metal) becomes large enough, then the government will start to build RDP houses like the ones pictured above. Each plot has its own electricity and water supply. Ideally, the plot owners are supposed to tear down their makookoos (the scrap metal homes) once the RDP home is built, but most of them will leave the standing on their plot and use it as a source of extra income from renting it out). The makookoos do not have water or electricity and are not nearly as well insulated as a RDP house (which is not well insulated either). 

RDP houses are designed with a kitchen/living area and two bedrooms for the entire household to share. So, as you can imagine, they are often times quite crowded and overpopulated. 

In addition to learning about the different types of houses, I learned that the family unit is often difficult to understand because you have grandmothers/aunts/great aunts/cousins etc. caring for children who's parents didn't want them or who have passed away. 

Families are often subsidized with a government grant for each child under the age of 14 (only 250 Rand/month, which is about the equivalent of $35), for adults and children with disabilities, or from a pension given to adults over the age of 60. Needless to say, there is not much money flowing through these townships and even though the government has amazing relief programs in place, there is not always enough tax payers' money to fund them.  

I'm hoping to learn a lot more about the townships tomorrow and hopefully I'll get the opportunity to do some of the work that the other girls got to do!

Universitas Days 3 & 4

Malnutrition Screenings
I had the opportunity to accompany the fourth year students on a few malnutrition screenings in some of the wards on Wednesday morning. In order to screen for malnutrition in the adult patients, the students measure the mid-upper arm circumference, ulnar length, knee to foot length, and full arm length. They also took a skin fold measurement of the arm on both men and women (using the tricep). The last thing that they did was inquire about any recent weight loss, and if there had been weight loss, then they asked for the time period in which the weight has been lost. 

Surgery ICU
In the surgical ICU ward, not all patients require a special feed. Some of them are placed on tube feeds, but others are allowed to eat a normal oral diet. It is always important to check blood results before writing a patient's diet because some factors could be indicative of nutritional status--typically albumen (a water soluble protein) is a marker for nutritional status and diagnosis. Prealbumen is a most indicative marker for nutritional status, but it is not typically measured. It is also important to know a patient's kidney status before prescribing protein because too much protein in the body could place pressure and potentially cause damage to the kidneys. 

The most interesting thing that I learned about today is known as refeeding syndrome.The following link really helped me to understand a little more about it: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC390152/

"Starting to eat again after a period of prolonged starvation seemed to precipitate cardiac failure. The pathophysiology of refeeding syndrome has now been established. In starvation the secretion of insulin is decreased in response to a reduced intake of carbohydrates. Instead fat and protein stores are catabolised to produce energy. This results in an intracellular loss of electrolytes, in particular phosphate. Malnourished patients' intracellular phosphate stores can be depleted despite normal serum phosphate concentrations. When they start to feed a sudden shift from fat to carbohydrate metabolism occurs and secretion of insulin increases. This stimulates cellular uptake of phosphate, which can lead to profound hypophosphataemia. This phenomenon usually occurs within four days of starting to feed again"
--Stephen D. Hearing

Multi-Disciplinary Team Meeting
Departments involved: psychology, physiology, dietetics, general practice, and social work.
This was a meeting held to discuss the "pain patients," those patients who have been admitted for chronic pain. It is a bit of a round table discussion put in place so that all doctors and other staff members assigned to these patients can help to fill the gaps in the patients' files. The team relies heavily on the Stages of Change model (precontemplation--contemplation--preparation--action--maintenance) to determine the patient's readiness and willingness to change and/or be helped in order to alleviate his or her pain. 

The most interesting thing that we discussed during this meeting was this small little piece of food for thought (may be a possible research study here!): Does working for a company that sells a certain product turn you off of that product (i.e. Does working for a fast food company turn you off of eating that company's food?). 

Despite all of the interesting things that I've learned this week, I think the biggest thing that I learned is that there is an obvious and distinct difference between public and private practices here. I think that Kalie may have mentioned this in one of her earlier blogs this week, but the difference that you see in the staff members is absolutely night and day. Those in the public practice are always moving to the next patient...not waiting to stay and talk to the patients, not trying to forge a relationship with them, but instead aiming to be efficient in their work and get as much done as possible. On the other hand, in the private sector, things move much slower. Staff members make an effort to get to know their patients and ensure that patients feel comfortable and satisfied before moving on to the next one. Social status is becoming more apparent and it has really opened my eyes to the differences in culture among ethnic groups in South Africa.

Universitas Day 2


Today I learned a little more about the in’s and out’s of the Health Care System in the Free State. For instance, there are three levels of Health Care in the Free State:

Level 1 includes a Primary Health Care Clinic, District Hospital, and a Community Health Care Center. Level 2 includes a Regional Hospital and Level 3 includes a Provincial Tertiary Hospital (I’m pretty sure this is what Universitas is).

The hospital also aims to follow eight “Batho Pele” principles to kickstart the transformation of service delivery:
  1. Consultation—you can tell us what you want from us
  2. Service standards—insist that our promises are kept
  3. Access—one and all should get their fair share
  4. Courtesy—don’t accept insensitive treatment
  5. Information—you’re entitled to full particulars
  6. Openness and transparency—administration must be an open book
  7. Redress—your complaints must spark positive action
  8. Value for your money—your money should be employed wisely.

They also believe that every patient or client has the following responsibilities (as set down by the Department of Health: Free State Provincial Government in The Patient’s Right Charter):
  • ·      To take care of his or her health
  • ·      To care for and protect the environment
  • ·      To respect the rights of other patients and health care providers
  • ·      To utilize the health care system properly and not abuse it
  • ·      To know his or her local health care services and what they offer
  • ·      To provide health care providers with the relevant and accurate information for diagnostic, treatment, rehabilitation, or counseling purposes
  • ·      To advise the health care provider on his or her wishes with regard to his or her death
  • ·      To comply with the prescribed treatment or rehabilitation procedures
  • ·      To enquire about the related costs of treatment and/or rehabilitation and to arrange for payment
  • ·      To take care of health records in his or her possession

Patients are categorized by economic status and in certain wards they are categorized by illness. For example, in the cardiothoracic ward, the patients who have tuberculosis are all placed in a room together in order to decrease the risk of infection for other patients in the ward. However, should there not be enough beds in the ward, other respiratory disease patients (i.e. those with pneumonia or asthma) are also placed in the same room as the tuberculosis patients.

Before delving in to everything I learned in the specific wards today, I think that it is also important to note that none of the wards have a room 13 because the staff and patients think that it is unlucky. So instead, the rooms jump from 12 to 14. Also, it is unethical to indicate a patient’s HIV status in his or her file, so staff members must read the medication lists before treating patients to see if they are on any HIV medications.

Now on to cardiothoracics and cardiovascular!

The dietician in charge of these units remains with the same patients during pre-op and post-op, which I think makes it a little easier for diagnosis and treatment. He compared diagnosis to being a CSI agent because in the patients’ files, the doctors rarely indicate the specific illness that has placed them in the hospital and the dieticians must put all of the clues together to figure out what to prescribe the patients. For example, a patient with pulmonary problems would be diagnosed with “Lung Disease” in his or her file, but in reality, they may have pneumonia, asthma, lung cancer, etc. So the dieticians must look up all of the medical history on the patient to determine what their complete illness is before prescribing different diet and supplement plans.

It is extremely important that they find out all the information that they can on each patient because different pulmonary illnesses require different diet and supplement plans. For example, those with COPD or Emphysema have difficulty exhaling and the carbon dioxide concentration in the blood increases, so dieticians must design a diet and supplement plan around that.

Patients that have a difficulty exhaling often experience a loss of appetite, decreased oxygen in the blood (which changes their ability to metabolize different foods), and a change in carbohydrate metabolism (some carbohydrates are released during exhalation and so a decreased rate of exhalation changes the carbohydrate balance in the body).

I also got to sit in on a diet history questionnaire (in English!), which was quite interesting. At Universitas, the diet history questionnaire looks a little something like this:
What time do you wake up?
What is the first thing that you eat or drink?
     Details? (quantity, how many times a day, etc)
When do you typically eat breakfast?
     What do you eat?
     How do you typically prepare it?
When is the next time you eat after breakfast?
     Details?
When do you eat dinner?
     What do you eat?
     How do you typically prepare it?
Do you eat anything after dinner?
How regularly do you eat your vegetable?
Who usually prepares your food?
Does your eating pattern differ on weekends?
Do you exercise?
Do you take any supplements?
How often to you drink water?
    Other beverages?

Once we finished the diet history, the dietician counseled the patient on how diet affects hypertension. Here’s the jist of what was said:

Increased salt in the diet can increase your blood pressure
You can substitute other seasonings for salt
Beware of hidden salt in processed foods
It is better to bake foods instead of frying them
It is important that you don’t add extra salt to a meal
The skin of a chicken has saturated fats, so it is important that you skin the chicken before you bake it
Be careful with “just add water” sauces and soups because they are often laden with salt
Always remove visible fat from meat before eating
Fish can help decrease blood pressure (omega 3 fatty acids for heart protection, calcium for strong bones, and antioxidants for a “body armor”)
2% or low fat milk is healthier than full cream milk
Always choose brown (whole wheat) bread over white bread
Fruit lowers blood pressure because potassium helps to lower the salt content in the body

The last things worth noting about today are some interesting tips on how to beat cancer. They include:

Enjoy more fruit and vegetables
Eat more food rich in fiber
Be more active
Eat less fat
Avoid processed meat like polony and viennas
Don’t smoke or drink alcohol
Avoid contact with poisons or chemicals

I’m hoping to go to a Multidisciplinary Team meeting on Thursday…but I’m sure that more interesting things are to come tomorrow!

Universitas Hospital Day 1

Universitas Hospital (Bloemfontein, South Africa)
Today was my first day at the University Hospital (one of Bloemfontein's tertiary government hospitals) and it certainly started out as quite an adventure. The dietetics department is hidden in the back of the hospital and through a gate (which you need a card or chip to get through...which I don't have) and so I got lost before I even started making rounds with the senior dieticians. Luckily, after I finagled my way to their offices, the rest of the day was very interesting and educational.

I began the day in the neurological ICU where patients are normally admitted with head trauma (due to fighting when under the influence of alcohol or car accidents) or brain aneurysms. Those patients with brain aneurysms typically also have hypertension, which is often times a contributing factor to the aneurysm. The dietician told me that one of the biggest problems in the ICU is infections. Patients on a ventilator are at a higher risk of contracting an infection than those who are not ventilated, and so those who are eventually able to be taken off ventilation have a better chance of survival.

Patients in the neurological ICU at Universitas feed for 18 hours a day and rest for the remaining 6 and are fed within the first 24 hours of admittance to the hospital. However, diabetic patients are fed 24 hours a day. It is important the the dieticians indicate the method of food consumption (i.e. via the mouth, a feeding tube, intravenously  etc) and that all formulas prescribed come from the same company. Dieticians do not restrict energy (caloric) intake for overweight and obese patients in this work and it is important that they look at the patient's urine for diagnostic purposes. The color of the urine helps the dieticians to assess if there is an infection in the kidneys or if medication is causing the discoloration.

I was quite surprised to see that even though this was an ICU, there were empty beds lining/blocking the hallways and the so called "isolation" rooms weren't exactly completely isolated. For example, one of the patients was isolated from the remainder of the ward, but the door between his room and the hallway (which was filled with nurses, doctors, stray beds, etc) was wide open the entire time we were making rounds. The nurses who cared for him we careful to wear smocks (not them I'm entirely sure that did anything for them), but did not utilize gloves or a face mask.

After visiting the neurological ICU, we moved forward to the neurology and neuro-surgical wards. The majority of the patients admitted in to this ward arrive malnourished and have poor dental hygiene, which causes them to struggle with eating solid foods. Therefore, they are given what are known as sip feeds, which is simply the oral intake of a liquid dietary supplement. The only restriction we discussed in this ward was the restriction of protein when a patient is in a coma or is severely disoriented.

It is also quite common for these patients to have co-morbidities and sometimes even auto-immune diseases. They are sometimes fastened to their beds (i.e. hands tied to the bed rails) so that they can not pull out their tubes.

Next was the high-care ward. High-care is a level of care between ICU and general wards. The nurse to patient ratio is 1:1 in high-care and these patients are too healthy for ICU and too sick for general wards. They are typically given pureed foods because it decreases the risk of asphyxiation.

The last thing I did today at Universitas was sit in on a couple of nutrition consultations and learn a little about the nutrition care process. Nutrition consultations are given when requested by a doctor for a patient that is struggling to eat the food being given to them or for those patients who will be discharged soon. They are typically done to help with a supplementation regimen or to help develop an at-home diet plan. If a patient is not being discharged immediately, then they require daily follow-up consultations. There are set menus for diabetic patients. Each plate will look exactly the same, but portion sizes are dependent on caloric restriction and intake levels. Otherwise, dieticians will work with the patients to help develop a diet plan that is right for them.

The Nutritional Care Process

I'm Back! :)


I  made it back from the Southern Free State! (And loved it!)

During my time there, I made the realization that their dietetics program seems to be a mixture between our nutrition and health promotion programs. During our time in the Southern Free State, we traveled around to different schools and clinics and gave presentations on different health topics (healthy eating, brushing your teeth and washing your hands properly, breastfeeding, malnutrition, and diabetes). For the purposes of condensing everything that I saw and did this week, I'm including the notes that we were given and those that I took during each lecture.

Monday, June 4th
Noordmansville Primary School

Do a talk on healthy eating, brushing teeth, and washing hands--should be very basic...the children are on in grades 1 and 2. Make sure that they understand...use posters and pictures. Give anything (like coloring picture or fruit...or anything small to be used in school). Approximately 108 children total.

This was by far my favorite talk...even though I didn't understand what was going on because it was all in Afrikaans. In order to demonstrate the passing of germs, we put glitter on our hands and then gave each of the children a high five. They were confused at first, but were very excited to get to interact with the big people. 


We stressed that it was important to wash their hands and brush their teeth to ensure that they removed all of the germs so that they wouldn't get sick. Just like in America, we suggested that they sing "Happy Birthday" to themselves twice to know how long each activity should take. 


In regards to healthy eating, the presenters started by explaining to the children what energy and base building foods were and then built a framework around that. They stressed the importance of getting enough protein, calcium, and fiber to keep them full and help them to build strong muscles and bones. At the end of the presentation, the children were each given an orange and a picture of dancing fruits that they could color in. 


Tuesday, June 5th
Edenburg Combined School

The group of 100+ students that we presented to. 

Problem: Teenagers tend to skip meals to lose weight and can't concentrate in school.
Talk should include: talk about the importance of healthy eating for teenagers and explain the physiology of why it's better to eat small frequent meals to lose weight instead of skipping meals. Also discuss the importance of eating a variety. The teenagers should understand the physiology and understand what a balanced meal is. Be practical...can maybe give examples of healthy eating meals and healthy alternatives for take-aways.

The most interesting thing about this talk was that in the auditorium, the boys sat on one side and the girls sat on the other. We gave this presentation in English, and so I actually helped to present the healthy meals and snacks. And given my strange and exotic (haha, yeah right) accent, I had their full and undivided attention.


The presentation was given in three parts:
1. Five things to remember (demonstrated on a hand)


  • Variety--it is important to eat a variety of foods and not just pap, russians, and other typical South African foods. 
  • Fruits and veggies--the South African dietary guidelines suggest "5 a day" (2 fruits, and 3 veggies)
  • Sugar--it is very important to keep an eye on the amount of sugar we intake each day...for instance, if your going to reach for a cold drink (aka soda), then it is important to choose something like Coke Light as opposed to its more sugary counterpart. 
  • Fat--a lot of foods have hidden fats and it is important that we are aware of which foods contain harmful amounts of fat. For example Russians (aka Polish Sausage) has a lot of hidden fat, but is one of the most commonly eaten meats in South Africa. We encouraged the children to watch their intake of fatty foods. 
  • Exercise--it's imperative that we exercise during the day. Luckily, the children's school offers either athletics of physical education type classes, so they are at least doing some type of physical activity during the week. 
2. The Physiology of Starvation


  • When you continuously skip meals, your body goes in to starvation mode and doesn't know how to digest your food properly. Therefore, when you do finally eat, your body hoards the nutrients because it doesn't know when your next meal is coming. Hence it's opposing effect on weight loss. Instead of losing weight, instead you tend to gain weight because of the body's hoarding tendencies.
3. Healthy Snacks and Meals (My section)

  • Based on guidelines given to me from the UFS students that I was accompanying, I suggested the following healthy snacks to the children as alternatives to their preferred Lay's and Simba chips: 
 Brown bread sandwich with peanut butter
    1. Popcorn (it provides fiber and will keep them feeling fuller for longer)
    2. Water and diet cold drinks (i.e. coke light) (Given that over 70% of your body is made of water, it is important that we replenish it during the day)
    3. Fruits and veggies (provide more vitamins and minerals than chips and other snacks)
    4. Peanuts and raisins (mmm....fiber and protein!)
    5. Low fat milk (full of protein and calcium and can help to prevent osteoporosis later in life)
  • Healthy Meals: 
    1. Scrambled/boiled eggs (as opposed to fried) with brown (wheat) bread
    2. Reheated pap with vegetables and meat (the re-heated pap lowers the GI and will curb their hunger for longer
    3. Stews with beans and lentils and soya mince
    4. Vegetable Soup
    5. Tinned fish with vegetables and re-heated pap
    6. Brown bread sandwich with peanut butter
Those were our two biggest presentations and two of the most important because we were speaking to the children...the future of South Africa. I can only hope that they take what we said to heart.

Wednesday, June 6th
Springfontein Clinic
Ante-natal breasfeeding talk (in Afrikaans/English)

During this talk, we discussed breast feeding recommendation, advantages of breastfeeding, proper attachment, and  proper positioning with four expectant mothers. They seemed very receptive to the information we were giving them and eager to put them in to practice when their babies arrived. 


Wednesday, June 6th
Springfontein Clinic
Information session to Sprinfontein Clinic personnel on identification and management of malnutrition.

I was quite honestly shocked that we were asked to give a presentation on malnutrition in a clinic where it appeared to be so prevalent, but happy that we could try to help in some way. To make this section a little easier, I will just give you an outline of what we talked about. 


Weight/Weighing
Make sure that the scale weighs accurately (It is important to zero the scale every day!)
The scale must be placed on a hard surface (They often place it on the beds)
If the child is <2, use a pediatric scale or tared weight (i.e. zeroed with a person on the scale)
If a child is >2, weigh the child alone if the child will stand still
It is important that the child is completely naked and that all procedures are explained to the mothers


Length/Height (there's a difference!)
Length--child is measured laying down (If a child is <2 years old)
Height--child is measured standing up (If a child is >2 years old)
Measuring tapes and mats are not recommended for taking measurements


Mid Upper Arm Circumference (MUAC)
Should be measured every 3 months and the date of the visit and the measurement should always be recorded
MUAC <11.cm is considered severe acute malnutrition and the child should be referred to a better medical facility IMMEDIATELY. 
MUAC >11.5 cm to <12.5 cm without edema indicates moderate acute malnutrition and the children should be supplemented and managed according to IMCI guidelines. 


Malnutrition
2 causes: decreased food consumption and/or illness 
Consequences: liver and kidney damage/failure, hypothermia, heart damage, gut damage, electrolyte and fluid imbalance in the body
4 main causes of death in children with severe malnutrition: heart failure, hypoglycemia, hypothermia, and infections


Growth Charts
There are 3 different types of growth charts used: weight-for-age, length/height-for-age, and weight-for-length/height. 


Clinical Signs
Marasmus (severe wasting)

  • Thin appearance, "old man" face
  • Apathy: the child is very quite and does not cry
  • The ribs and bones are easily seen
  • The skin under the upper arms appears loose
  • On the back, the ribs and shoulder bones are easily seen
  • In extreme cases of wasting, the skin on the buttocks has a "baggy pants" look
  • No bilateral pitting edema 
These children have lost fat and muscle and will weight less than other children of similar height 


Kwashiorkor (bilateral pitting edema)

  • "Moon face"
  • Dermatosis: flaky skin or patches of abnormally light or dark skin (in severe cases) 
  • Apathy, little energy
  • Loss of appetite
  • Hair changes
  • Irritable, cries easily
Marasmic Kwashiorkor

  • Bilateral pitting edema and severe wasting
It was sad to witness some of the malnourished children come in to the clinic, but hopefully this presentation will help the Sisters (aka Nurses) to refer them to the bigger hospitals. 

Thursday, June 7th
Edenburg
Our last presentation! This presentation was given to about 20 women who lived in a township and covered sugar disease (aka diabetes). It was given in Afrikaans, so I didn't understand exactly what was going on, but the senior dietitian used food models and pictures to demonstrate and reiterate her point, so I was able to follow along slowly. 

All in all, I'd say that I learned A LOT this week and I'm very thankful that this was part of our program. Hopefully next week in the Universitas Hospital will be as much of a learning experience!

Blood pressures, blood glucose, and urine analysis

Yesterday while we were sitting in our "lecture," I noticed that here they go in to a lot more depth and hands on experience than we do in the States. Provided I am not a Nutrition major, but I have heard from Kalie and Brittany that over here, the students go through much more clinical and hands on practice before they graduate than similar programs in the US.

For example, during our Friday lecture, we practiced taking blood pressures, urine analysis, and blood glucose levels. As a Health Promotion major, I have learned to take blood pressure before and so that part was a review for me and Ryland, but Kalie and Brittany had not yet learned how to do it (and I don't think that they would have in our Nutrition program).

It was also very interesting that after they explained how to measure blood glucose levels, we were sent to practice on each other. Meaning, we were given a finger prick needle and told to go to town. At first Kalie and I both tried to prick our own fingers...but we both jumped when we pulled the trigger and so the lab instructor had to prick them for us. As we were practicing all of these skills, I sat there and wondered if this would ever be done in the US. Blood pressure measurements, sure, but blood glucose analysis? I was just so shocked that they let us stick each other with needles...although they were small, it still made me nervous.

Other than that, I didn't experience too much of a culture shock this week because I was shadowing dietitians in the private sector and wasn't really exposed to the public sector at all. Next week I'm going to the Southern Free State where I think I will see a little more of rural South African culture...and hopefully will have more to blog about!

Probiotics and Antioxidants


Today, we talked a lot about probiotics and antioxidants at the hospital. According to the dieticians, physicians in South Africa are wary of the use of probiotics, and so I thought I would go in to a little more research to see how much they are used in the US. 

As of 2008, a review article published by Vanderhoof and Young showed that there is a validated indication for the use of some probiotics in the US. However, they have discovered that there is a need to clarify the regulatory and safety issues. So perhaps South Africa and the United States can figure out the benefits and consequences together. All I know is that I will have to keep an eye out for more knowledge on probiotics upon my return home.

As for antioxidants…I know that they are all the rage in the US. For example…why do you think so many people drink a glass of red wine a day? Oh right…antioxidants.

In addition to these riveting topics, we also talked about how your diet can affect arthritis pain, so I decided to do a little more research on that too. Here’s what I came up with:

Researchers have found that the Mediterranean diet had the greatest effect at reducing arthritis pain. The Mediterranean diet emphases foods like fruits, vegetables, grains, fish and olive oil, while limiting the amount of red meat. In a study done, in 12 weeks, people on the diet reported 15% less pain, but no improvements in physical function or morning stiffness. A vegetarian diet that allowed eggs and dairy products had a similar effect.

On the other hand, some foods like potatoes and tomatoes have long been said to contribute to arthritis pain. Some researchers have speculated that a group of compounds in the vegetables called alkaloids might worsen inflammation in sensitive people. But so far, no solid studies have confirmed this.

Interestingly, the dietician I was working with today suggested that her patient try to increase the amount of omega 3 fatty acids that she was consuming each week. Omega 3’s are found in fish (salmon, tuna, and halibut), some plants, and nut oils. Omega 3’s have been shown to have an anti-inflammatory effect on the body and may help to reduce the swelling of arthritis patients. She also suggested a diet high in green, leafy vegetables.

Needless to say, I think that this might be an interesting field of study upon my return.

Day 1

Today was our first day in the internship and I'm starting out with my first week in the Medi-Clinic. At the Medi-Clinic, I will be working with a dietitian who has her own private practice and works in the private sector. It is her job to ensure that the patients in pediatric and neonatal intensive care units are receiving the proper nutritional supplements to aid in their growth and healing. In order to do this, she calculates their energy needs based on their weight and health condition and then counsels the doctors about appropriate levels for liquid and protein supplementation. When a patient is being released from the hospital, she will then counsel the family on how to move forward.

After shadowing Vandghie, I shadowed one of her partners, Anna Marie, while she did the same nutrition counseling for adults in an intensive care unit and those who are part of an assisted living community. They both said that the rest of the week would be much of the same old thing.

However, I did have the opportunity to chat with both of them about different cultural practices in South Africa in comparison to those in the States. Vandghi and I talked about the differences between the public and private sectors in SA and how most people would not be able to afford the private sector without medical aid (something that is very similar to our health insurance). In terms of the public sector, the government subsidizes the facilities and as we may all assume, they are not in the best conditions.

While traveling to and from different hospitals, Anna Marie and I talked about the different cultural practices of Black South Africans. She was telling me how it is often a struggle to work in the public sector as a white woman because they don't always respect or believe in what she is telling them. For example, the Black community does not believe in birth control or family planning, so they will give birth to many children without the means of supporting them throughout their lives. In fact, many black men will impregnate a woman before marrying her to ensure that she is able to give birth to his children. Often times, these women will be left behind in the dust to raise the children on their own. It's really quite sad.

Anna Marie also told me about her research in breast feeding and how she's been reading the Healthy People 2020/2010 goals. I got really excited when I knew exactly what she was talking about--as a health promotion student, we discuss the Healthy People goals often. We also talked about the WHO and CDC. It was nice to have a conversation that didn't deal strictly with nutrition.
