Treating hypertension helps lower dementia risk in older adults
Jairia Dela Cruz, 25 Sep 2023
Older adults with hypertension who are on blood pressure (BP)-lowering medications are better protected against dementia than those with untreated hypertension, and this is true across all ages in late life, according to an individual participant data meta-analysis.
Deep brain stimulation safe, feasible for poststroke rehabilitation

Updates on migraine management with rimegepant
03 Sep 2023

Migraine is a debilitating neurological condition that affects millions of people worldwide, causing intense headaches, sensory disturbances, and a significant decline in quality of life. Approximately one-third of patients encounter aura, which encompasses transient focal neurological disturbances that precede the attack. [Lancet 2017;390:1211-1259; Headache 2021;61:1021-1039]

Long COVID: What we have learned so far
Prof. Ghassan Dbaibo, 27 Apr 2023

The WHO defines long COVID as a condition that occurs 3 months from COVID-19 onset, whose symptoms last ≥2 months and cannot be attributed to an alternative diagnosis. In an interview with MIMS Doctor, Professor Ghassan Dbaibo of the Center for Infectious Diseases, American University of Beirut, Beirut, Lebanon, describes the evolving attitudes towards long COVID among healthcare professionals (HCPs), some unexpected predisposing factors, potential biological mechanisms behind prolonged symptom duration and shares data on vaccination’s protective effects against long COVID.

Optimizing executive function skills in children: What healthcare professionals should know
Dr. Evelyn Law, 04 Feb 2023
Executive function (EF) skills in childhood predict academic success better than a child’s intelligence quotient (IQ), and are associated with better physical health, more stable careers, and higher socioeconomic status in adulthood. [Psychol Sci 2005;16:939-944; J Clin Psychiatry 2012;73:941-950; Pediatrics 2013;131:637-644] Despite this, EF is an important topic that is often overlooked. To learn more about EF, MIMS Doctor interviewed Dr Evelyn Law, a clinician scientist specialising in developmental and behavioural paediatrics. Dr Law is Assistant Professor at the National University of Singapore Yong Loo Lin School of Medicine, Singapore.
Optimal protection in geriatric patients with atrial fibrillation: An expert’s perspective
Prof. Olivier Hanon, 01 Apr 2022
Geriatric patients with atrial fibrillation (AF) are at increased risk of blood clots that can lodge in the brain and cause fatal strokes. At a recent webinar, Professor Olivier Hanon, Head of Geriatrics Department in Broca Hospital, Paris, France, shared insights on how to optimally protect geriatric patients with AF, with a special focus on direct oral anticoagulants (DOACs), particularly rivaroxaban, for stroke prevention in AF.
Addressing the unmet needs and challenges in managing older AF patients
Dr. Tan Vern Hsen, Dr. Barbara Helen Rosario, 01 Apr 2022
A key focus in the management of atrial fibrillation (AF) in older patients is stroke prevention through oral anticoagulation. However, a significant proportion of older AF patients remain undercoagulated due to the perceived bleeding risk of oral anticoagulants (OACs). Dr Tan Vern Hsen, Senior Consultant, Department of Cardiology, Changi General Hospital, Singapore, and Dr Barbara Helen Rosario, Senior Consultant, Department of Geriatric Medicine, Changi General Hospital, Singapore, shared their respective insights into managing older AF patients for an integrated approach.
Practical considerations in the choice of pharmacological therapy (VKAs vs NOACs) for venous thromboembolism
Dr. Lim Lay Cheng, 28 Dec 2021
Venous thromboembolism (VTE) is a serious medical condition. It comprises deep vein thrombosis and pulmonary embolism. Left untreated, it could result in significant morbidity and mortality. Most patients with VTE receive anticoagulation therapy for 3 months or longer. For more than 50 years since the 1940s, vitamin K antagonists (VKAs) such as warfarin were the mainstay of oral anticoagulation therapy for VTE. As it has a narrow therapeutic index, VKAs require frequent coagulation monitoring with International Normalised Ratio (INR) to adjust and optimize the dose for each individual. As the peak effect for warfarin takes at least 4-5 days, in the initial stage of VTE, concurrent administration of daily subcutaneous injections of low molecular weight heparin (LMWH) is needed until INR reaches therapeutic levels. Due to numerous drug and dietary interactions with warfarin, regular INR monitoring is required to ensure therapeutic levels are maintained and to avoid under or overdosing.
Apixaban in the management of nonvalvular atrial fibrillation in older patients: Clinical evidence and experience sharing
Dr. Soon Chao Yang, 28 Dec 2021
Nonvalvular atrial fibrillation (NVAF) raises the risk of stroke by three to five times, particularly in older patients. Treating older patients with NVAF presents special challenges because of their elevated risks for both stroke and bleeding. This necessitates optimization of anticoagulant therapy by balancing efficacy and bleeding risk. Non-vitamin K antagonist oral anticoagulants (NOACs), such as apixaban, have shown advantages in safety and efficacy over warfarin, which has a very narrow therapeutic index. In an interview with Dr Soon Chao Yang, Cardiologist at The Heart Doctors Clinic, Mount Alvernia Hospital, Singapore, he shared insights on managing NVAF in older patients, as well as his experience with using apixaban in this special population.
