Editorial ReviewInterventional pain management in patients with cancer-related pain.
Invasive interventional procedures for managing pain in cancer patients are often underutilized following the popularization of the WHO analgesic ladder. The procedures that were successfully used until then were relegated away from mainstream palliative care practice, with the advent of newer opioids and adjuvants. Even though nerve blocks, intrathecal pumps and spinal cord stimulation were reintroduced as the fourth step of the WHO ladder, often referrals for these procedures are too late to produce a meaningful effect on quality of life. ⋯ ITDDs, neuromodulation and ever-increasing use of procedures routinely used in treating chronic nonmalignant pain would be the mainstay of interventional management until AI and nanotechnology would open doors for novel treatment options. Interventions should not be used as a last resort after multiple failed attempts at opioid therapy, but as an integral part of a management strategy including medical management, psychological and emotional welfare, and supportive care of the patient in a holistic manner. The curriculum of specialists should include appropriate training to safely perform and produce better quality evidence to validate the efficacy and safety of these challenging procedures.

Scientific independence and objectivity: many questions linger about treatment of type 2 diabetes, such as scientific study design, optimal glucose control and the safety of injecting exogenous insulin.
Whilst clinical guidelines exist for the treatment of people with type 2 diabetes, many underlying assumptions are still not qualified by convincing evidence. In this commentary, it is argued that fundamental issues still cloud clinical practice, such as biases in the design of clinical studies, the association between glucose control & clinical outcomes, and the safety of exposure to exogenous insulin and other glucose-lowering drugs. Relevant scientific evidence and alternative opinions about important issues continue to be largely ignored, and no effort has been made to resolve these questions. This may have had serious consequences, such as stifling innovation because there are no further benefits to be achieved in relation to glucose control.

ReviewOral semaglutide in patients with type 2 diabetes and cardiovascular disease, renal impairment, or other comorbidities, and in older patients.
Patients with type 2 diabetes (T2D) often have comorbidities, such as cardiovascular disease or chronic kidney disease, and a large and growing proportion of the T2D patient population is over 65 years. There are many therapies for the treatment of T2D but not all are suitable for patients with comorbidities. Oral semaglutide is a tablet formulation of a glucagon-like peptide-1 receptor agonist (GLP-1RA) and was recently approved for the treatment of T2D, representing an oral alternative to injectable GLP-1RAs. ⋯ There was no effect of age on glycemic efficacy of oral semaglutide and the presence of upper gastrointestinal disease or hepatic impairment did not affect the pharmacokinetics of semaglutide. Across the trials, the safety profile of oral semaglutide was as expected for a GLP-1RA, with gastrointestinal adverse events most commonly reported. As such, oral semaglutide provides an effective oral GLP-1RA treatment option in older patients and/or those with comorbidities, with no requirements for dose adjustment.

ReviewIntegrating oral semaglutide into clinical practice in primary care: for whom, when, and how?
Oral semaglutide is the first US Food and Drug Administration-approved oral glucagon-like peptide-1 receptor agonist (GLP-1RA) for the treatment of type 2 diabetes (T2D). Prior articles within this supplement reviewed the PIONEER trial program, which demonstrated that oral semaglutide reduced glycated hemoglobin and body weight when given to patients with uncontrolled T2D on various background therapies, and had a safety profile consistent with subcutaneous GLP-1RAs. This article provides guidance on integrating oral semaglutide into clinical practice in primary care. ⋯ Those managing patients should be aware of the potential impact of these dosing conditions on concomitant medications. When counseling patients, it is important to discuss these administration instructions, realistic therapeutic expectations, and strategies for mitigation of gastrointestinal events. Oral semaglutide provides a new option for add-on to initial T2D therapy (or later in the treatment paradigm), with the potential to enable more patients to benefit from the improvements in glycemic control, reductions in body weight, and low risk of hypoglycemia afforded by GLP-1RAs.

Practical guidance for use of oral semaglutide in primary care: a narrative review.
As the cornerstone of type 2 diabetes (T2D) management within the community, primary care providers are now faced with the challenge of not only managing diabetes itself, but also preventing hypoglycemia and weight gain associated with intensive disease management, and reducing cardiovascular risk. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are well established as efficacious treatments for T2D, and the safety/tolerability profile of this drug class is well defined. However, despite their beneficial effects, GLP-1RAs are under-utilized, highlighting the need for novel approaches to increase their use in primary care. ⋯ Due to the formulation of oral semaglutide, clinicians need to be aware of specific considerations in order to ensure optimal use. Such considerations include dosing conditions and use of concomitant medications. This article provides practical guidance on the use of oral semaglutide in the primary care setting, based on evidence from clinical studies, including the phase 3a PIONEER program, and the authors' clinical experience.
