Eczematous dermatitis is a major cause of recalcitrant pruritic eruptions in older adults. Although some medications have been implicated, there are limited data demonstrating the utility of medication changes. To investigate the utility and possible harms of drug cessation trials (DCTs) in chronic eczematous eruptions in the aging (CEEA). This is a retrospective cohort study utilizing electronic health records of DCTs in adults older than 65 years with CEEA. We identified 646 patients >65 years with new onset eczematous eruptions, 89 (14%) of whom had no identifiable etiology. In this cohort, 35 patients underwent a total of 40 DCTs. Although there was mention of improvement in 17.5% (7/40), all patients sought tertiary care for their persistent rash. Negative outcomes occurred in 45% (18/40), all of which were due to exacerbation of a comorbidity that the medication was prescribed to treat. Our experience suggests that patients with CEEA undergo DCTs that do not improve their dermatitis and can lead to dangerous worsening of underlying conditions. Further study of the etiology of CEEA is needed.

Insulin aspart, a rapid-acting analog, achieves faster subcutaneous absorption than regular insulin. This study aimed to demonstrate equivalence in the pharmacokinetic (PK) and pharmacodynamic (PD) characteristics of Recombinant Human Insulin Aspart from BioGenomics Limited (as test) and Novo-Nordisk (as reference) in healthy adult males. This was a double-blind, randomized, cross-over study, assessing PK and PD parameters under fasting conditions.

Purpose Of Review: Complex Regional Pain Syndrome (CRPS) is a neuropathic pain disorder characterized by pain disproportionate to the inciting event that is constant for an extended duration. Numerous treatment options for this condition have been explored with unsatisfactory results in many cases. Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist typically used as an anesthetic and analgesic, presents a promising potential treatment for CRPS in patients who fail to respond to traditional therapies.

Objective And Rationale: This study assessed support for novel tobacco compared with alcohol control policies among adults in Great Britain in 2021-2023. Objectives were to assess 1) overall level of support for tobacco compared to alcohol control policies; 2) level of support for tobacco compared to alcohol control policies among people who smoke tobacco or who consume alcohol at increasing and higher risk levels, or who do both; 3) level of support for tobacco compared to alcohol control policies among different sociodemographic groups?

Methods: Data were collected in September/October 2021-2023 in a monthly population-based survey on smoking and drinking behaviour of adults across Great Britain (N = 6311), weighted to match the overall population. Outcome measure was level of support for each seven tobacco and alcohol control policies.
