3D Imaging May Improve Surgery Outcomes





By Amadeo Constanzo
  
3D imaging technology adopted from other industries (such as gaming and entertainment) is becoming a real game changer in medicine.  The new 3D tools import MRI or CT scans and render these images into virtual 3D images, allowing the surgeons to plan in great detail before cutting open the patient.  There have also been advances in 3D imaging in endoscopic surgery where the 3D images guide the surgeon in real-time to perform the surgery with greater precision.  

Dr. James Chandler and Dr. Orin Bloch, neurosurgeons at Northwestern University, have started using such 3D endoscopic systems to more precisely remove brain tumors in patients.  The 3D technology allows the surgeon to see more vividly, enabling them to remove all traces of the tumor and less non-cancerous tissue.  The precision allows for less cutting and therefore, a speedier recovery for the patient after surgery.  More importantly, the added precision is crucial in lowering the known risks in brain surgery – coma, vision loss, and loss of speech.



For breast cancer patients, 3D imaging technology is beginning to improve detection and post-surgery outcome.  With traditional mammogram, tumors in hidden shadows are often undetected.  “The problem of overlapping shadows has confounded breast cancer screening because mammograms don’t show cancers that are hidden by overlapping tissue,” says Dr. Kyle Myers, Director of FDA’s Division of Imaging, Diagnostics, and Software Reliability.  The newer technologies of 3D breast tomosynthesis and 3D ultrasound and breast computerized tomography would enable the doctor to see the tumors in these hidden areas.  Two of the new technology have already been approved by the FDA, the GE Healthcare SenoClaire and the Selenia Dimensions 3D System.

Even without expensive 3D imaging systems, some tech savvy doctors are exploring the use of consumer 3D technology to improve surgery outcomes.  Take the case of a pediatric cardiologist, Dr. Redmond Burke of Nicklaus Children’s Hospital, who used Google Cardboard to successfully operate on a baby, Teegan Lexcen, with an abnormal heart.  Dr. Burke used an app called Sketchfab to render the baby’s CT scans into 3D visuals on the iPhone.  With the iPhone and Google Cardboard, he visualized the surgery in virtual reality.

“I think about heart repairs in three dimensions,” said Dr. Burke.  3D imaging sure makes that easier.  



Other doctors had already concluded that Teegan was inoperable but 3D imaging enabled Dr. Burke to successfully operate on Teegan by allowing him to plan out every incision and every step of the surgery in 3D.  This decreased the amount of time the infant stayed cut opened and it was crucial because the more time spent in heart surgery for a baby, the higher the chances of heart and brain damage.

Despite the many reported cases of 3D imaging technology producing favorable results, more studies will need to be done to quantitatively confirm surgery success rates from the implementation of 3D imaging technology.  However, it all looks very promising from what we’ve seen so far.

Healing and Faith: Accounted for in Medicine





Although there are some things not in your control, you have more control over the outcome (your healing) than you think. Faith plays a role in medicine. Part of it is documented in science as the placebo and nocebo effect. (It is so powerful that they have to account for it in most studies, to prevent it from skewing the studies.) Beyond science and medicine, your faith plays a much bigger role in your healing than you think. What is faith? It's probably not what you think.

For Eyes, Lutein and Zeaxanthin Foods




As at least one eye doctor has informed me, almost everyone will develop some type of eye disease leading to blindness, if they live long enough.  The few who do not develop these eye diseases as they get older are those who have the habit of eating 5 to 9 servings of fruits and/or vegetables a day, especially fruits and vegetables that contain lutein and zeaxanthin.  Such fruits and vegetables include oranges, carrots, brocolli, brussel sprouts, spinach, cantaloupes, nectarines, and papayas.

"Lutein and zeaxanthin are non-provitamin A carotenoids. They are antioxidants that are concentrated in the macula of our eyes. Eating a diet high in fruits and vegetables that are rich in lutein and zeaxanthan may reduce the risk for macular degeneration [as well as other eye diseases].  It’s important to get our antioxidants from foods! Beta-carotene supplements have been found to have no effect on risk for these eye diseases."  



If you want to make it simpler, I (personally) just go with the (previous) USDA recommendation of 5 to 9 servings of vegetables and/or fruits per day.  In addition to healthier eyes, another good effect from this simple practice is having better skin, getting slimmer, and looking younger than your age.  Also, with this simple practice, you are less likely to get other serious and common diseases as you get older.

To make it even easier, one way to fulfill this quota is to simply aim for 3 servings of fruits and/or vegetables per meal.  For example, have one apple + one orange + one serving of spinach before you eat the rest of the meal. (The rest of the meal would likely be less healthy).

Iron Supplementation for Borderline Anemic and Others





People take iron supplementation (along with folate and vitamin B12) for a variety of reasons, such as borderline anemia, pregnancy, preparation for pregnancy, attention deficit, menstrual bleeding, and fatigue.

Iron Overdose and Poisoning
Here's the first thing you need to know about iron supplementation. Inappropriate iron supplementation may lead to iron overdose, iron poisoning, and even death (especially in children) which are not as uncommon as you may think.




Daily Iron Requirements
You need a strategy that includes both iron-rich food and supplementation, not just supplementation alone.  You need both food and supplementation to effectively replenish your iron stores in your blood (to normalize hemoglobin and hematocrit levels).  People with the highest needs (such as anemics and pregnant women) require approximately 27mg of iron per day.  Other females (with lower requirements) need about 18mg per day.  Most males need approximately 10mg of iron per day.  Your supplementation of iron should not exceed 27 mg of iron per day.  You can (and should) get a little bit more from food, in addition to supplementation.  Generally, you cannot overdose on iron from FOOD that naturally contain iron.


What You Do For High-Iron-Need Cases (such as borderline anemia and pregnancy)

  1. Everyday, take a multivitamin with approximately 27mg of Iron, 800mcg of Folate/Folic Acid, and 2.6mcg of Vitamin B12  (such as Centrum Prenatal, even if you are not a pregnant female.  If not Centrum Prenatal, choose another well-known brand from a well established company.)
  2. Eat two of the foods from the list/table below (of foods with iron, folate, and vitamin B12)
  3. As much as possible, eat a fruit high in vitamin C (such as orange, kiwi, or mango) immediately after eating iron-containing foods.  For example, you can eat an orange after snacking on cereal containing iron.
  4. Aim to have 5 to 9 servings of vegetables and/or fruits each day

Foods with Iron, Folate, and B12

Iron Folate B12
Fortified Cereals ~ 18 mg ~ 100 mcg ~ 6 mcg
Spinach ~ 3mg ~ 131 mcg
Fish ~ 1 mg ~ 12 mcg ~ 3 mcg
Chicken ~ 1 mg ~ 12 mcg ~ 0.3 mcg
Fortified Cereals ~ 18 mg ~ 100 mcg ~ 6 mcg
Nuts ~ 1 mg ~ 20 mcg
Beef ~ 2 mg ~ 7 mcg ~ 0.5 mcg
Beans ~ 1 - 6 mg ~ 40 mcg ~ 1 mcg





What You Need to Do If You Are a Lower-Need Case
  1. Daily, take a multivitamin with 10 - 18mg of iron.  (Choose a well-known brand.  I take Centrum.)  
  2. Eat two of the foods from the list/table above  (of foods with iron, folate, and vitamin B12)
  3. As much as possible, eat a fruit high in vitamin C (such as orange, kiwi, or mango) immediately after eating iron-containing foods.  For example, you can eat an orange after snacking on cereal containing iron.
  4. Aim to have 5 to 9 servings of vegetables and/or fruits per day.


If the 1-2-3 Above Is Not Sufficient
Keep in mind any nutritional strategy for iron may require a month to a year before your body's iron reserves are fully replenished (depending on the individual case).  You have to persist in continuing with the appropriate 1-2-3-4 habit above.  If the 1-2-3-4 above is not sufficient, add the following:

5. When taking your multivitamin and when eating the foods with iron (on the list above), avoid milk, antacids, other food with calcium, tea, coffee, and caffeine.  Calcium and caffeine inhibit the absorption of  iron.

6. Eat oysters or other seafood occasionally, but only occasionally.  Oysters and other seafood contain a good amount of iron, but they are generally considered unhealthy and may in the long term cause other health problems.  Therefore, eat seafood only occasionally.  Remember to eat an orange or something with vitamin C immediately after eating iron-rich foods.

People with Back Problems and Spinal Problems




This post is for people dealing with back problems and for people dealing with people with back problems.  This post is inspired by Steve Nash, his back problems, and the criticism he has received because he’s still swinging a golf club.  I have to say something about this because it hits home for me (since I have pre-existing back problems too, although my back problems are now under control and I am now back pain free thanks to God and thanks to my SpirFit knowledge, including knowledge of appropriate exercises.)  It baffles me how some people think it’s okay to criticize or even make fun of you in your pain. 

If You Know Someone With Spinal or Back Problems
When it comes to spinal conditions, or back problems, different cases are individualistically different.  Some may have trouble swinging a golf club while others do not (but any one of them will probably still have a lot of pain if they have to play high level NBA basketball games.) 

Just like with any medical condition, different patients experience things differently.  It is unbelievable how people can criticize someone with medical problems, problems that they do not understand.  If you don’t understand, just shut up with it, because God may punish you for this and give you the same pain.  Trust me, pain from spinal problems is something you don’t want.  As a Chinese saying goes, “You understand a needle is painful, but you don’t really understand until the needle penetrates your own skin and bone.”

The criticisms and negative comments toward Steve Nash is literally “adding insult to injury” and it’s appalling.  You are doing the same if you ever criticize someone in their pain or medical problem that you don’t understand (even if you think you do).  Don’t do that.

If You Have Back Problems
Also, if you have back problems, generally you should continue to engage in any physical activity that does not aggravate the problem or does not exacerbate the pain.  Physical activity that does not aggravate the problem actually helps you heal.  Inactivity actually will make your back problems worse.  This is backed up by medical literature.  Any good orthopedic doctor or doctor of physical therapy can confirm this.  For Steve Nash, if swinging a golf club and hiking does not give him much pain, then engaging in such physical activities actual helps the condition.  If chasing opponents like Steph Curry up and down the basketball court in NBA games aggravates his spine, then he needs to take a break to recover (especially when he’s 40 or above) before attempting to play at that level again.  From someone who knows spinal problems firsthand (and knows some of the medical literature on this), it seems like Steve Nash is doing exactly the right thing
