La nueva tecnología desarrollada por TransMedics, una compañía de biotecnología con sede en EE. UU., Puede hacer latir a un corazón humano hasta que llegue a la sala de operaciones para el trasplante!.
Los científicos dicen que los órganos transportados de esta manera son más viables y podrían aumentar la cantidad de corazones trasplantables en un 15-30 %, salvando las vidas de más pacientes que esperan un nuevo corazón.
Después de una "muerte circulatoria", el corazón deja de latir y el tejido ya no está oxigenado. El músculo cardíaco se deteriora rápidamente a temperatura ambiente, y estos corazones ya no son adecuados para la donación. Los métodos actuales de extracción de órganos enfrían el cuerpo de un donante con muerte cerebral cuyo corazón aún funciona. Una vez que el corazón deja de moverse, se corta del cuerpo y se transporta a 4 grados centígrados al receptor que espera.
El transporte en frío ha sido la norma en la ciencia de trasplantes desde su inicio, pero ahora los investigadores se preguntan si el transporte en caliente podría ser mejor. Según MIT Technology Review, los equipos de investigación de todo el mundo están trabajando en sistemas de perfusión cálida, máquinas que pueden mantener los órganos vivos hasta que estén listos para el trasplante.
Korkut Uygun, cirujano de trasplantes y fundador de Organ Solution, dijo a MIT Technology Review: "Lo frío es lo viejo y lo cálido lo nuevo". Cálido es el camino a seguir con el tejido metabólicamente activo ”. Los sistemas en desarrollo en Organ Solution así como en compañías similares, Organox en Oxford y Organ Assist en los Países Bajos, están perfeccionando estos sistemas de transporte cálido para riñones e hígados, pero estas mismas ideas podrían ¿Se aplicará a los trasplantes de corazón? Un equipo de investigación de TransMedics dice "sí". Llamado "corazón en una caja".

Cervical Screening Test – This is an important screening test to pick up signs of irregularities that could lead to cervical cancer if not treated. Cervical cancer is one of the most preventable cancers. As of December 2017, the Pap test has been replaced by the Cervical Screening Test, which detects human papillomavirus (HP )Cervical Screening Tests are necessary if you have ever been sexually active. Your first Cervical Screening Test should be two years after your last Pap test. You will be invited to have your Cervical Screening Test when you are due to participate, via the National Cancer Screening Register. It is recommended that you have the test every five years until you are 74. Even if you have had the HPV vaccine, it is important to continue to have regular Cervical Screening Tests
STI screening – if you are under 30 years of age and sexually active, have a urine test for chlamydia each year, as chlamydia can affect your fertility and often has no symptoms. If you have sex with one or more new partners without a condom, it is recommended that you talk to your doctor about checking for other sexually transmissible infections
pregnancy check-up – have a general check-up before planning a pregnancy to discuss any pregnancy health risks. Once you are pregnant, regular antenatal checks help monitor your baby’s development, pick up abnormalities and assess your health. Tests include ultrasound scans, urine tests and blood tests.Dr Venkat Kasina is a experienced gynaecologist working at the High Road Specialists clinic.Dr Kasina has appointments available for women’s health checks Ph 9259 5971 Fax 6162 2755.Check out Dr Kasina online www.highroadspecialists.com.au #doctor#at#the#high#road#specialists#for#gynecology#fax#faxon#faxts#or#phone#woman#women#health#check#regular#monday#gynecologist
THIS GUY just finished his last bit of research for the year which means we have the next two (almost THREE) weeks off to relax and recuperate before another crazy semester followed by clerkship! At this point we have a routine figured out for when exams roll around... read about how we juggle med school exams with life and everything it comes with 😅 click the link in my bio to read the full post!

Experiencing chronic pains in your gut, difficulty swallowing or recurrent diarrhea?
These may be a sign of a more serious root cause that is best diagnosed with an endoscopy. Accurate diagnosis is crucial in order for the problem to be fully taken care of. #guteducation
“Hi I’m your doctor, Dr. Nickels. “
Yes I’m old enough.
Yes I’m a woman.
Yes I have adequate training.
Yes I really am the doctor. -
I go through this scenario almost daily when I admit new patients. Sometimes it’s unspoken but I can tell by the patient or their family’s reaction what is implied. Usually I laugh it off and make some kind of quick joke that I’m even younger than they think, or thank them for making me feel young and make a dig at the grey hairs I’ve accumulated through residency. Recently however one of our patients asked my male resident in front of the entire team : “How do you feel about having a woman as your boss?” I immediately countered back to the patient “Well how do you feel about having a woman as your doctor?”... initially he was at a loss for words being taken off guard but then smiled, shook my hand and said “I think it’s great!” Doctors are not all mid aged white males and nurses are not all young women anymore. More than half of Med students are females these days and an increasing number of males are going into nursing. It’s awesome! Yet, most of our patients are still surprised when they get anyone other than an older white male as their doctor or a young female as their nurse. I think it’s important for the patient to have confidence in each and every member of their healthcare team and maybe one day I won’t have to reassure my patients that I’m qualified... but until then I will continue to stick up for myself and what I’ve worked so hard for. -shout out to @teawithmd for getting the conversation started about this topic!

Removal of surgical staples! Have you tried them before?
Surgical staples, tissue adhesives, surgical tape and sutures are widely used methods to close surgical wounds or trauma injuries. More commonly used with larger, deeper wounds, surgical staples are faster to apply than sutures or stitches, and associated with fewer wound infections.
Surgical staples are ready to be removed when the sewn tissue has healed well enough that the staples are no longer needed. Also, it's important that no drainage is noticed, and there are no signs of infection. The removal procedure requires specialized equipment and skill, and needs to be completed by a healthcare professional in a sterile environment, such as a hospital or medical clinic. Staples are usually removed 7 to 14 days after they are placed, but this length of time depends on the healing rate, as well as the size and depth of the wound.

💎🏩🌟 Sometimes our hardships help others✨❄️👩🏼⚕️
And we have to learn that through uncomfortable situations. Every time I think I’m going to be celebrating finishing something (like ICU and now new patient visits in the Clinic 😬🤷🏼♀️), God has a way of bringing me back to the important things in life. My last patient of the day was one I was hoping did not show up. I know that sounds really bad that as a doctor I’d hope for a patient to not show for an appointment, but yesterday, I saw that this particular patient was seeing me for a hospital discharge follow up. During the hospitalization, she was diagnosed with stage IV pancreatic cancer. Yup, just like mom. And now I was expected to pull myself together and discuss it with her. She was over ten minutes late for the appointment and my nurse asked if I’d still be willing to see her—ugh, yes of course I will. Despite my reluctance, I sat down with her and her daughter allowed them to share their story—and then I shared mine as well. She shared her faith in Jesus and I shared mine and my mom’s. It was the most valuable appointment of my day, of my week, maybe even my entire year. Instead of feeling sadness, I felt relief. And I think they felt comfort. Her daughter asked if I was taking new patients, and I had to confess—nope, today was my last day accepting new patients in the clinic. And instead of being happy about this (because outpatient internal medicine isn’t my favorite 😬), I actually was a little sad that I wouldn’t be able to continue supporting them through their story. .
God uses people we meet and encounters in our everyday lives to fill our hearts and remind us why we go through hardship. Instead of falling into the trap of “God, why me?” let us think, “God, who and what are you preparing me for?” ❤️
I was going to post this earlier but didn’t have the heart...
CARDIAC MRI (CMR)
👨🏽💻Both interventional coronary artery angiogram and CT coronary angiogram look to see if the coronary arteries are physically blocked. If an artery is blocked you should just open it up right? Well if the heart muscle that artery is supplying is completely infarcted, putting someone through an invasive procedure doesn’t have any benefit
👨🏽💻So how do we find out if the heart muscle is ‘viable’? Traditionally exercise ECG tests have helped us here and more recently stress echo, nuclear stress tests and now CMR
👨🏽💻CMR can give us detailed assessment of what we may see on Echo (ie heart chamber size and wall thickness, valve stenosis/regurgitation) so it is useful in diagnosing cardiomyopathies. Where CMR really comes into its own is in giving us information about whether there is scar tissue in the myocardium suggesting an infarct
👨🏽💻By giving IV contrast (gadolinium based agents) we look to see if there is late enhancement in the LV wall with different patterns giving us a different idea about the underlying pathology:
▫️subendocardial (ie close to the cavity) leading to whole wall in a vascular territory: ischaemia
▫️patchy mid wall/epicardial: myocarditis, cardiomyopathy, infiltrative (eg sarcoid, amyloid)
👨🏽💻If more than 50% thickness of the LV wall is infarcted this is deemed ‘non-viable’ so opening up the vessel usually won’t help. What’s more we can stress patients with adenosine and see if we can induce ischaemia giving us more of an idea about viability - the CE-MARC trial showed CMR to have diagnostic superiority over nuclear SPECT for assessing coronary disease which is why it is increasingly performed in Europe
Plus I just think it looks cool....
