Objective: The Asia-Pacific region (APAC) represents a unique environment for the publication of biomedical research, particularly industry-funded research. Awareness and adoption of international guidelines on ethical publication practices continues to increase across APAC, but the reframing and expansion of many of the recommendations in the Good Publication Practice (GPP) 2022 guidelines versus GPP3 published in 2015 have important implications for publishing industry-funded biomedical research in the region.

Methods: This manuscript provides practical guidance for stakeholders in APAC on interpreting and applying the recommendations made in the GPP 2022 guidelines.

Numerous recommendations and guidelines aim to improve the quality, timeliness and transparency of medical publications. However, these guidelines use ambiguous language that can be challenging to interpret, particularly for speakers of English as a second language. Cultural expectations within the Asia-Pacific region raise additional challenges and several studies have suggested that awareness and application of ethical publication practices in the Asia-Pacific region is relatively low compared with other regions.

Despite an estimated 2 million osteoporosis (OP)-related fractures annually, quality of care for post-fracture OP management remains low. This study aimed to identify patient and provider characteristics associated with achieving or not achieving optimal post-fracture OP management, as defined by the current HEDIS quality measure. The study included women 67 to 85 years of age, with ≥1 fracture, and continuous enrollment in a Humana insurance plan.

Background: Lack of medication adherence is associated with significant morbidity and mortality, particularly among minorities. We aim to identify predictors of nonadherence to antiplatelet medications at the time of percutaneous coronary intervention (PCI) with stent among African American and Hispanic patients.

Methods: We used data collected for a randomized clinical trial that recruited 452 minority patients from a large US health insurance organization in 2010 post-PCI to compare telephone-based motivational interviewing by trained nurses with an educational video.

Background: Minorities have lower adherence to cardiovascular medications and have worst cardiovascular outcomes post coronary stent placement

Objective: The aim of this study is to compare the efficacy of phone-delivered Motivational Interviewing (MINT) to an educational video at improving adherence to antiplatelet medications among insured minorities.

Design: This was a randomized study.

Participants: We identified minorities with a recently placed coronary stent from an administrative data set by using a previously validated algorithm.

Objective: The undertreatment of ethnic minority children with ADHD prompted a study on the effects of methylphenidate (MPH) on the executive functions of African American children with ADHD.

Method: Nineteen African American children with ADHD are tested on the Tower of Hanoi (TOH) and the Paired Associates Learning Task (PAL) in a double-blind crossover acute challenge of MPH and placebo.

Results: Under MPH, TOH rule breaks decrease, especially in the second testing session, and TOH planning time increases, particularly for incorrect solutions; PAL recall in the final learning trial improves with MPH.

Physician office settings play an important role in tobacco cessation intervention. However, few tobacco cessation trials are conducted at these sites, in part because of the many challenges associated with recruiting community physician offices into research. The present study identified and implemented strategies for recruiting physician offices into a randomized clinical trial of tobacco screening and cessation interventions with adolescent patients.
