When You No Longer Need Opioids

More cancer drug treatments to be subsidised under changes to MediShield Life

You should not stop taking opioids suddenly. People who need or want to stop taking opioids are usually tapered off the medicine slowly so that their bodies have time to adjust to it. If you stop taking opioids suddenly and develop a flu-like illness, excessive sweating, diarrhea, or any other unusual reaction, tell your doctor or nurse. These symptoms can be treated and tend to go away in a few days or weeks. Again, slowly decreasing your opioid dose over time usually keeps these kinds of symptoms from happening. Check with your doctor about the best way to taper off your pain medicines.

How Nsclc Is Treated

In cancer care, different types of doctors often work together to create a patients overall treatment plan that combines different types of treatments. This is called a multidisciplinary team. Cancer care teams include a variety of other health care professionals, such as physician assistants, nurse practitioners, oncology nurses, social workers, pharmacists, counselors, dietitians, and others.

There are 5 main ways to treat NSCLC:

  • Surgery

  • Targeted therapy

  • Immunotherapy

The common types of treatments used for NSCLC are described below, followed by an outline of the common treatment plans by stage. Your care plan also includes treatment for symptoms and side effects, an important part of cancer care.

Treatment options and recommendations depend on several factors, including the type and stage of cancer, possible side effects, and the patients preferences and overall health. Take time to learn about all of your treatment options and be sure to ask questions about things that are unclear. Talk with your doctor about the goals of each treatment and what you can expect while receiving the treatment. These types of talks are called shared decision-making. Shared decision-making is when you and your doctors work together to choose treatments that fit the goals of your care. Shared decision-making is particularly important for NSCLC because there are different treatment options. Learn more about making treatment decisions.

The Tetracyclines: Doxycycline Provides Proof

Tetracycline is a broad-spectrum antibiotic that is commonly used for the treatment many bacterial infections, and functions as an inhibitor of protein synthesis in bacteria. Today, it is mainly used for the treatment of acne. However, the term tetracyclines is also used to describe a class of related semi-synthetic derivatives, that all contain the same chemically-conserved four-member ring structure, that is characteristic of tetracycline. Tetracyclines show bacterio-static activity against nearly all aerobic and anaerobic bacteria, including both Gram-positive and Gram-negative types. Tetracyclines inhibit protein synthesis by preventing the binding of activated aminoacyl-tRNAs to the A-site on the 30S subunit of bacterial ribosomes. As such, they reversibly inhibit the addition of new amino acids to the growing polypeptide chain, during protein synthesis. Importantly, the 30S bacterial ribosome is homologous the 28S mitochondrial ribosome, accounting for the manageable side-effects of the tetracyclines. As a consequence, tetracycline-based antibiotics are inhibitors of mitochondrial biogenesis. Doxycycline is a tetracycline-derivative with markedly improved efficacy and stability, which was first FDA-approved in the late 1960s, nearly 50 years ago now.

Treating Infections In Cancer Patients

Fever, swelling, pain, and other signs of infection in a person known to have a weak immune system are treated as medical emergencies. In the past, people with cancer were almost always put in the hospital to treat infections, and some still are. But many patients can take their antibiotics at home as pills or liquids. Those who need intravenous antibiotics may be able to get them in infusion clinics, doctors offices, or even at home. If this happens, talk to your cancer care team to learn where you can receive treatment.

For the first few days, patients should be assessed daily to see if the infection is getting better and to see if they are having any side effects. The doctor might also want you to have lab tests often during treatment. If the patient still has a fever during treatment, they should be assessed daily by their cancer care team. Anti-infectives may be changed or new ones may be started when the final culture or other test results come in. The culture results should tell the doctor which germ is causing the infection.

If the patient doesnt get better, an infectious disease specialist may be called in. These are doctors who specialize in treating infections. This doctor may recommend extra testing and different treatments.

Each type of infection is treated with different drugs and for different lengths of time. If you have any questions about the drugs you are given or why youre taking them, talk with your doctor or nurse.

The Glycylcyclines: Tigecycline Shows Efficacy

List of common drugs used in the Cancer Chemotherapy ...

The glycylcyclines are a relatively new antibiotic class that are highly-related to the tetracyclines. The glycylcyclines were designed to specifically overcome tetracycline resistance. They have essentially the same mechanism of action as the tetracyclines, as they prevent bacterial protein synthesis. Both tetracyclines and glycylcyclines bind to the 30S bacterial ribosomal subunit, thereby inhibiting the binding of a given aminoacyl-tRNA to the A-site of the ribosome. Importantly, it appears that glycylcyclines bind more tightly to the ribosome, than the tetracyclines. Currently, tigecycline is the only FDA-approved glycylcycline. Similarly, the glycylcyclines are inhibitors of mitochondrial biogenesis.

Interestingly, quantitatively similar results were obtained with tigecycline, as compared with doxycycline, showing that it also has the capacity to inhibit tumor-sphere formation, across all 10 cell lines tested. Tigecycline was first tested for its ability to inhibit mammo-sphere formation using MCF7 and T47D cells, over a concentration range, from 10 µM to 50 µM. Interestingly, in both MCF7 and T47D cells, tigecycline inhibited mammo-sphere formation with an IC-50 between 10 and 25 µM . For simplicity, we used a single concentration of 50 µM, in all eight other cell lines, which significantly inhibited tumor-sphere formation .

Use Those Antibiotics Wisely Especially If Youre A Cancer Patient

Antibiotics are a critical tool for fighting infections, especially in cancer patients who may have compromised immune systems. But like any tool, it may lose its edge and impact if it’s overused. “In a cancer patient, we need to be extremely careful, because they are immune-compromised,” says Mashiul Chowdhury, MD, Chief of Infectious Diseases at Cancer Treatment Centers of America® . “They need antibiotics, but you dont want to lose that battle. You have to keep your antibiotics tool very sharp. In order to keep that tool sharp, you have to make sure you are using the right antibiotic at the right time.”

When Taking An Antibiotic

It is important to take antibiotics in the correct way. If you do not, this may reduce how well they work. For example, some antibiotics need to be taken with food and others should be taken on an empty stomach. If you do not take your antibiotics in the right way it will affect how much of them get into your body and therefore they may not work as well. So, follow the instructions as given by your doctor and on the leaflet that comes with the antibiotic you are prescribed.

Always take the entire course of antibiotics as directed by your doctor. Even though you may feel better before your medicine is entirely gone, follow through and take the entire course. This is important for your healing. If an antibiotic is stopped in mid-course, germs may be partially treated and not completely killed. Bacteria may then become resistant to that antibiotic.

Overuse of antibiotics has led to some bacteria changing their form or structure and becoming resistant to some antibiotics, which may then not work when really needed. For example, meticillin-resistant Staphylococcus aureus is a bacterium that has become resistant to many different antibiotics and is difficult to treat. Other bacteria produce chemicals called enzymes such as extended-spectrum beta-lactamases which allow them to be resistant to certain antibiotics.

How Antibiotic Resistance Develops

Antibiotics help our bodies to kill the types of bacteria that make us sick.

Some of the bacteria that make us sick get better at defending themselves against antibiotics, meaning resistant bacteria are harder to kill. This is called antibiotic resistance.

The resistant bacteria start to multiply, making our antibiotics less and less effective.

Cancer Drugs To Be Added To List Of Subsidised Drugs Fewer Patients To Pay Out

Doctors Object to High Cancer Drug Prices

SINGAPORE – Another 55 cancer drugs will be added to Singapore’s list of subsidised drugs following negotiations with pharmaceutical companies, which have allowed the Republic to secure the drugs at lower prices.

These additions to the Standard Drug List and Medication Assistance Fund will mean increased funding for around 150 cancer treatments, said the Ministry of Health on Tuesday .

It added that eligibility criteria for the MAF – which subsidises expensive drugs that have been deemed necessary – will also be expanded from September next year.

With this, Singaporeans with a per capita household income of up to $6,500 will qualify for drug subsidies, for cancer as well as other ailments.

At present, only people earning a per capita household income of $2,800 and below can get help from the scheme.

In its statement, MOH also said MediSave withdrawal limits for cancer drugs will be tweaked in tandem with the latest changes to MediShield Life claim limits.

Currently, people can draw up to $1,200 a month for all cancer drug treatments and related services, such as blood tests. When the changes take effect next year, these withdrawal limits will go down to $600 for some people, depending on the type of drugs they are using.

In comparison, about 70 per cent of all subsidised patients taking cancer drugs now have their bills fully covered.

What Are The Possible Side

It is not possible in this leaflet to list all the possible side-effects of each antibiotic. However, as with all medicines, there are a number of side-effects that have been reported with each of the different antibiotics. If you want more information specific to your antibiotic then you should read the information leaflet that comes with the medicine.

Most side-effects of antibiotics are not serious. Common side-effects include soft stools , diarrhoea, or mild stomach upset such as feeling sick . Less commonly, some people have an allergic reaction to an antibiotic and some have died from a severe allergic reaction – this is very rare.

Antibiotics can kill off normal defence bacteria which live in the bowel and vagina. This may then allow thrush or other bad bacteria to grow.

You should tell your doctor if you have any of the following side-effects:

Some antibiotics may interact with other medicines that you might take. This may cause reactions, or reduce the effectiveness of one or other of the treatments. So, when you are prescribed an antibiotic you should tell a doctor if you take other medicines.

Proven And Potential Molecular Mechanism For Cancer Treatment With Antibiotics

On the one hand, anticancer antibiotics can kill cells in the whole proliferation cycle, even G0 phase cells, thereby achieving the anti-proliferation ability of cancer cells by affecting the cell cycle, such an example with cyclinenon-specific drugs . On the other hand, anticancer antibiotics can promote apoptosis of cancer cells by targeting apoptotic gene B cell lymphoma-2 , apoptotic pro-Bcl-2-associated x , caspase-3/8/9 and cancer suppressor gene P53, thereby impacting cancer cell apoptosis in patients . In addition, anticancer antibiotics can be used as regulatory agents of EMT to inhibit the metastasis of cancer cells and play an anti-metastasis role . For example, ciprofloxacin has pro-apoptosis ability while salinomycin can inhibit proliferation and EMT in the development of cancers .

Many experts have found that, in particular, cancers tend to be more sensitive to emerging classes of anticancer antibiotics that they have never been exposed to before and that these agents are more effective in inhibiting cancers than those to which the cancer patients have previously been exposed. From the initial anticancer antibiotics such as doxorubicin, epirubicin and mitomycin to the anticancer antibiotics adriamycin, salinomycin and fluoroquinolones discovered in the latest research, the treatment of antibiotics for cancer has become increasingly important.

How To Get Proper Pain Relief With Opioids

If you feel the drug is not helping to control your pain, talk with your doctor. When a medicine doesnt give you the pain relief you need, your doctor may prescribe a higher dose or tell you to take it more often. When your cancer care team is working closely with you, doses of strong opioids can be raised safely to ease severe pain. Dont decide to take more pain medicine on your own. If changing the dose doesnt work, your doctor may prescribe a different drug or add a new drug to the one youre taking.

If your pain relief isnt lasting long enough, ask your doctor about extended-release medicines that come in pills and patches. These can control your pain for a longer period of time.

If your pain is controlled most of the time, but you sometimes have breakthrough pain, your doctor may prescribe a fast-acting medicine or immediate-release opioid that will give you faster pain relief right when its needed.

Adverse Effects Of Amoxicillin May Be Potentially Under

The list of oncology drugs that were identified with ...

the Oncology Nurse Advisor take:

Amoxicillin is a widely used antibiotic in the penicillin group of drugs. It is used to treat bacterial infections in patients with cancer, and may be used as prophylaxis in some patients. In a systematic review, researchers conducted a review of controlled trials to assess potential harms related to amoxicillin use.

The review included a total of 45 trials, featuring a total of 10,519 participants. The researchers found that almost twice as many patients receiving amoxicillin had diarrhea compared with patients receiving placebo, and diarrhea was more than three times more likely among participants receiving amoxicillin-clavulanate. An association between candidiasis and amoxicillin-clavulanic acid use was also observed.

However, the authors acknowledge a limitation to their study. All the trials measured efficacy rather than harm as their primary outcome, and only 25 of the study included information on harms. Therefore, the number of harms reported was lower than expected, which contributed to a conclusion that harms may be under-reported in clinical trials. In a related commentary, clinicians are advised to be wary of the lack of information on potential adverse effects from amoxicillin.

Clinical Study Of Psychedelic Drugs For Cancer Patients Could Be A Game Changer

Every year, hundreds of thousands of people in America develop depression and anxiety as a result of a cancer diagnosis. As of now, there isnt much physicians can do to treat those conditions, says Dr. Anna Beck, an oncologist and the director of end-of-life care at Huntsman Cancer Institute.

You cant throw medications for anxiety or depression at this kind of existential distress, Beck said. You need something thats really kind of out of the box.

In the spirit of out-of-the-box thinking, Beck and a team of researchers at Huntsman are exploring an experimental treatment for the demoralization and anxiety that often accompany cancer: group psychedelic therapy.

They want to see whether group psychotherapy, combined with psilocybin, the active ingredient in magic mushrooms, can safely help people confront the sense of their own mortality.

Psychedelic medicine is the only thing that has been shown to make a difference in terms of alleviating some of the existential distress , Beck said.

Transformational Research

Psychedelics like psilocybin and LSD were studied extensively by scientists in the 1950s, 60s and into the 70s.Early research demonstrated the drugs could be valuable in treating the existential distress of cancer patients. Arenaissance ofpsychedelic research in the past 20 years has built and improved upon the findings of those early studies.

And he said those remarkable benefits seem to last.

Cytotoxics And Targeted Therapies

Targeted therapies are a relatively new class of cancer drugs that can overcome many of the issues seen with the use of cytotoxics. They are divided into two groups: small molecule and antibodies. The massive toxicity seen with the use of cytotoxics is due to the lack of cell specificity of the drugs. They will kill any rapidly dividing cell, tumor or normal. Targeted therapies are designed to affect cellular proteins or processes that are utilised by the cancer cells. This allows a high dose to cancer tissues with a relatively low dose to other tissues. Although the side effects are often less severe than that seen of cytotoxic chemotherapeutics, life-threatening effects can occur. Initially, the targeted therapeutics were supposed to be solely selective for one protein. Now it is clear that there is often a range of protein targets that the drug can bind. An example target for targeted therapy is the BCR-ABL1 protein produced from the Philadelphia chromosome, a genetic lesion found commonly in chronic myelogenous leukemia and in some patients with acute lymphoblastic leukemia. This fusion protein has enzyme activity that can be inhibited by imatinib, a small molecule drug.

How Does Antibiotic Resistance Impact Cancer Care Outcomes

AMR also undermines key advances being made in cancer care by adversely affecting cancer treatment outcomes and threatening the survival of people living with cancer.

There has been substantial progress in cancer care in the past decades, with key advances in surgery, radiotherapy and medicines, including the newer immunotherapies. The significant and growing threat of drug-resistant bacteria, however, is undermining all the above-mentioned efforts in cancer treatment. In fact, cancer care is highly affected by AMR. People with cancer are more susceptible to infections due to the lowering of immune defences, while surgery and treatments like bone marrow transplants, radiotherapy and chemotherapy put the immune system under immense pressure.

As many as 1 in 5 cancer patients undergoing treatment are hospitalised due to infection, and antibiotics are the main line of defence. Pneumonia and sepsis are among the most frequent causes of admission to intensive care units for cancer patients. In fact, it is estimated that 8.5% of cancer deaths are due to severe sepsis.

Antibiotics are a key and indispensable part of cancer treatment many patients simply have to take them and we owe it to them to better manage our use of the drugs and address this crisis, which could roll back progress made to date in cancer treatment.
