Weekly semaglutide injectable has been around for some years now. Even with my special interest in diabetes and obesity, I am getting confused with all the clinical trials involving semaglutide in patients with obesity with or without diabetes. They all have very innovative acronyms most of them starting with “S” which makes them hard to keep track of.…

I must admit that I have been doing this for many years on an ad hoc basis. I have been screening for helicobacter pylori (HP) infection in patients who need to be on aspirin (primary or secondary prevention of coronary artery disease). This isn’t what is recommended in any cardiovascular (CV) disease guidelines until recently but the evidence is not robust.…

Digitalis is one of the oldest drugs in cardiovascular (CV) medicine and has generally been used in patients with heart failure (HF) and in those with atrial fibrillation (AF) or in both (1,2). In fact, up until 25 years ago, digitalis in the form of digoxin was used in around two thirds of patients with moderate to severe heart failure.…

We all have patients at risk of thromboembolism (mainly from atrial fibrillation risks) and atherosclerotic cardiovascular disease (primarily, coronary artery disease). They may require both anti-coagulant as well as anti-platelet therapy. Sometimes, we don’t have a choice as they have high risks for both. Theoretically, they at high bleeding risks. Yet, our cardiology colleagues have to make that difficult decision to continue both.…

Not very often do you come across two significant studies on the same topic within weeks of each other. Over the last two months, two very interesting trials reported on the influence of exercise and fitness on risk of colorectal cancer (CRC) and the risk of recurrence of CRC. We know that being overweight or obese confer significantly higher risks of at least 13 different cancers (1,2).…

We always worry when athlete patients take supplements to improve their workout and performance. We don’t really know what these “supplements” are. We don’t really know whether they work or whether they are safe. One of the most commonly used supplements is creatine. Does it help muscle building and performance? Does it help to lose fat?…

We have explored the association between intensive endurance athletes and cardiovascular events in the past. Data on the dose–response relationship between long-term intensive endurance exercise and coronary heart disease has been rather conflicting over the years. While early studies suggest that regular endurance athletes have lower ischaemic heart disease (1), later studies reported an increased prevalence of coronary atherosclerotic plaques amongst highly trained athletes in comparison to healthy non-athletes (2–4).…

We are all aware of the four pillars of treatment in the guideline directed medical treatment (GDMT) of patients with heart failure with reduced ejection fraction (HFrEF) – SGLT2 inhibitors (SGLT2i), angiotensin receptor neprilysin inhibitor (ARNI), beta blockers and mineralocorticoid receptor antagonist (MRA). When we come to heart failure with preserved ejection fraction (HRpEF), the pillar of treatment is rather lonely – SGLT2i only.…

It’s amazing how we have learnt to accept declining muscle function and increasing frailty as part of our patients getting older. At GPVoice, we have explored muscle health and sarcopenia many times over the couple of years. We know that declining muscle health is associated not only with falls risk but also with increase mortality rates in COPD, heart disease, osteoporosis and post surgical outcomes.…

You would have no doubt noticed headlines everywhere about the new criteria for GDM diagnosis that was just released a few days ago. Why is there such a buzz? Why is everyone seemingly that excited? We have covered many of the issues covered by ADIPS over the years leading up to this new guideline.…

There are many reasons why some of our patients go vegetarian. A primarily plant-based diet with less meat is supposed to lower the morbidity of chronic diseases, including cardiovascular diseases, type 2 diabetes, and certain cancers [1]. Some patients may choose to reduce their food-related ecological footprint. A transition to a diet that contains more plant-based products and less meat could increase food availability while releasing the burden on the environment [2].…

Papillary thyroid carcinoma (PTC) is the most prevalent type of thyroid malignancy, accounting for approximately 75–90% of all thyroid cancer cases (Cozens, 2011; Solbiati et al., 2017). These tumours are typically slow-growing and display distinctive histologic features, including papillary structures, nuclear alterations, and multiple subtypes (Gonzalez-Gonzalez et al., 2011; Limaiem et al., 2023). The prognosis is generally favourable, with survival rates exceeding 90% and low mortality rates, ranging from 4–8% (Cozens, 2011; Solbiati et al., 2017).…
