Scientists develop method to help epidemiologists map spread of COVID-19

Scientists have developed a method they believe will help epidemiologists more efficiently predict the spread of the COVID-19 pandemic. Their new study outlines a solution to the SIR epidemic model, which is commonly used to predict how many people are susceptible to, infected by, and recovered from viral epidemics.

Answers to Common Questions About Radiofrequency Ablation For Cancer

Radiofrequency ablation (RFA) is a procedure that relies on electrical energy to kill cancer cells without removing them with surgery. According to Cancer.Org, this technique is most effective in patients with small tumors, or when a cancer patient is not an ideal candidate for surgery. 

Here are some of the most common questions about radiofrequency ablation for cancer:

 

1. How does radiofrequency ablation work? 

A radiologist inserts a thin needle through an incision in the skin near the cancer tissue, guided by a piece of imaging equipment, such as an ultrasound or an MRI (magnetic resonance imaging). This thin needle is charged with high-frequency energy that heats up and kills the cancer cells.

Because it is a minimally invasive procedure, the cancer patient may not need to stay in the facility or clinic although, for some individuals, the RFA might be done in the operating room where the patient is given general anesthesia.

2. What type of cancer is most commonly treated with RFA?

Radiofrequency ablation works best against liver cancer as well as colon cancer with liver metastasis. In general, however, RFA is best for tumors with a diameter of less than one and a half inches.

Doctors usually consider RFA as an option if the patient’s tumor is quite difficult to reach with surgery or if the patient has a medical condition that will make surgery a significant risk. If a patient with liver tumors has had chemotherapy without good results, and it’s not possible to remove the tumors surgically, then an RFA may also be undertaken.

 

3. What can a patient expect to feel during and after the procedure?

There’s a slight pinch on the needle insertion site and the patient may feel some pressure during the insertion of the catheter in the artery or vein. The patient may also feel some discomfort on the site of the incision, but this may be dulled with an anesthetic. 

However, if the doctor decides to sedate the patient, then he or she won’t feel any discomfort. Doctors may need to attach other equipment to your body to monitor your blood pressure and heart rate. 

After the procedure, the patient may experience some pain in the IV or injection site, which can be managed with pain medications. Patients will have to be in the recovery room for a few hours, as they may experience nausea when the effect of the anesthesia is wearing off.

At Dr. William’s Atlanta Cancer Institute, patients are carefully screened and assessed to make sure that they are good candidates for the procedure. Our doctors also encourage patients to ask any questions they might have to clear their doubts and ensure full cooperation.

Image analysis technique provides better understanding of heart cell defects

Many patients with heart disease face limited treatment options. Fortunately, stem cell biology has enabled researchers to produce large numbers of cardiomyocytes, which may be used in drug screens and cell-based therapies. However, current image analysis techniques don't allow researchers to analyze heterogeneous, multidirectional, striated myofibrils typical of immature cells. Researchers showcase an algorithm that combines gradient methods with fast Fourier transforms to quantify myofibril structures in heart cells.

Subcellular chatter regulates longevity

As people get older, they often feel less energetic, mobile or active. This may be due in part to a decline in mitochondria, the tiny powerhouses inside of our cells, which provide energy and regulate metabolism. In fact, mitochondria decline with age not only in humans, but in many species. Why they do so is not well understood. Scientists set out to understand how mitochondrial function is diminished with age and to find factors that prevent this process. They found that communication between mitochondria and other parts of the cell plays a key role.

Advantages of Intratumoral Immunotherapy in Cancer Treatment

Intratumoral immunotherapy is a revolutionary cancer treatment that makes use of sophisticated antibodies, which are directly injected into the cancer tumors, instead of intravenously.

This new cancer treatment immunotherapy can dramatically improve a cancer patient’s response rate, along with many other advantages.

 

Tumor against itself

The word itself, intratumoral, means within a tumor. Experts think that the best way to cure cancer is to use what’s already in the patient’s body, which means using cancer against itself. 

A cancer patient’s immune system may target cancer cells and kill them before they overrun the body. However, the immune system sometimes needs a little nudge and this is where intratumoral immunotherapy could help. 

According to experts, intratumoral immunotherapy optimizes cancer cells to work like a vaccine. It also inhibits the growth of the tumor as the tumor cells are injected with antibodies.

This process allows the patient to have cancer treatments with few side effects, unlike other methods. This also cuts the cost of expensive cancer treatments, while giving patients higher chances of survival and longer life.

 

How Does Intratumoral Immunotherapy Work? 

After the ablation of the tumor deposits either by heating or freezing, any non-viable cells that remain in the patient’s body may be used to stimulate the immune system with intratumoral immunotherapy. Doctors will use an -OX40 agonist combined with other types of cancer medication or vaccine — such as CpG, ipilimumab, and ketorolac — for the therapy, as in the case of stage 4 breast cancer patient with two liver metastases. 

In this case, following the therapy, a CT scan was performed on the patient six weeks after the procedure, and a positron emission tomography (PET) scan with a CT scan was also done 12 weeks after the therapy. The results showed that the cancer tumors were no longer found in the body, and the liver metastases had rescinded. 

 

Can Intratumoral Immunotherapy Work With Other Therapies?

Patients who are undergoing intravenous immunotherapy may consider intratumoral immunotherapy to enhance their treatments or add this to their radiation treatments or chemotherapy. According to experts, combination treatments are actually helpful, cost-effective, and safer for cancer patients since the therapy is more targeted. Furthermore, the effects of immunotherapy and ablation, when combined, are synergistic.

Cancer treatments, in general, open different challenges both in the clinical and economic sense. Some patients also respond better to specific therapies than other patients. We strongly encourage patients to discuss their options thoroughly with our doctors at Williams Cancer Institute before proceeding with the treatments.

Dr. Jason Williams’ approach combines interventional radiology expertise with a high level of knowledge about the science of immunology, cancer, and cancer immunotherapy.

Study tracks COVID-19 spread in pediatric dialysis unit

As COVID-19 continues its sweep around the globe, dialysis units have continued to be hotspots for the virus' spread. Researchers hope to combat that threat, through a novel study that used antibody testing on patients, doctors, nurses and staff within the unit to track symptomatic and asymptomatic spread in a confined space.

Surplus antioxidants are pathogenic for hearts and skeletal muscle

Oxidative stress can be pathological. Now researchers report that the other end of the redox spectrum, reductive stress, is also pathological. Reductive stress causes pathological heart enlargement and diastolic dysfunction in a mouse model.

The exposome: When our environment drives health and disease

The exposome is the sum of all the environmental drivers of health and diseases: a combination of external factors such as chemicals contained in the air, water or food, and of internal components produced by our organism in response to various stress factors. This very complex set of elements is continually evolving, and to map it fully is a challenging undertaking.
