The current guideline-based management of hypothyroidism recommends monotherapy with levothyroxine (LT4), titrated to maintain the level of thyrotropin within a euthyroid reference range. This has been successful for most people with hypothyroidism, but a substantial minority still report symptoms of hypothyroidism unexplained by a comorbid medical condition. LT4 is essentially a prodrug for triiodothyronine (T3), the thyroid hormone that acts on target tissues in the brain and the periphery. ⋯ Accordingly, these RCTs may have failed to demonstrate benefits of combination therapy in individual hypothyroid phenotypes. The pharmacokinetics of LT4 and T3 also differ, which is a barrier to their co-administration. Future clinical trials using LT4 + T3 tablets better suited for combination therapy will resolve the outstanding research questions relating to the place of LT4 + T3 combination therapy in the management of hypothyroidism.

To provide a contemporary overview of recent real-world lipid-lowering therapy (LLT) practices and outcomes in patients with hypercholesterolemia/dyslipidemia at high/very high risk of atherosclerotic cardiovascular disease in Europe. ⋯ LDL-C control is suboptimal and the available LLT armamentarium, most importantly combination therapy, is being underutilized in high/very high risk patients leading to inadequate management of cardiovascular risk.

This study synthesized evidence regarding the prevalence of post-traumatic stress disorder (PTSD) in the United States (US). ⋯ PTSD prevalence estimates varied widely, partly due to different study designs, populations, and methodologies, and recent nationally representative estimates were lacking. Efforts to increase PTSD screening and improve disease awareness may allow for a better detection and management of PTSD.

Review Case Reports
Angiotensin-converting enzyme inhibitors induced angioedema: not always a class effect? A case report and short narrative review.
Bradykinin-mediated angioedema is a rare but potentially fatal adverse event. Angioedema induced by angiotensin-converting enzyme (ACE) inhibitors is generally attributed to an inhibition of bradykinin degradation following ACE inhibition. Clinical studies on ACE inhibitors mainly focus on their efficacy. Few examine their potential to generate undesirable adverse effects, particularly with regard to angioedema. ⋯ Our clinical case suggests that despite similar pharmacodynamic properties, quinapril and ramipril do not have the same potential to generate angioedema. To explain this difference, we suggest a potentiation of the effect of bradykinin at the B2 receptor level by ramipril, which does not occur with quinapril. Consequently, angioedema may not always be a class effect of ACE inhibitors.

Pentasa (prolonged-release mesalazine [5-ASA]) has been available for >30 years as an effective treatment for mild-to-moderate ulcerative colitis (UC). A systematic literature review and meta-analysis was undertaken to provide an up-to-date evaluation of oral Pentasa efficacy and safety for induction and maintenance of remission. ⋯ This study confirms oral Pentasa is efficacious and well-tolerated in treating active UC and maintaining remission. The availability of multiple forms of Pentasa supports physicians' ability to individualize treatment and optimize dosing to improve outcomes.
