The aim of clinical research is to impart knowledge that will improve human health or improve understanding of human physiology. Although, till the end of 20 century pregnancy was always under exclusion criteria, now pervasive exclusion of pregnant women in clinical trials is currently not justified. Pregnancy brings in an array of anatomical, physiological and biochemical changes that can impact the pharmacokinetics of important medications. Pregnancy is often accompanied by chronic diseases like diabetes, hypertension, tuberculosis, HIV, depression which can require long term therapy. This indicates a need for studies being conducted exclusively in pregnant women. Current communication narrates ethical and regulatory aspects of inclusion of pregnant women in clinical trials.

The recent move to require sex as a biological variable (SABV), which includes gender, into the reporting of research published by the American Journal of Physiology - Heart and Circulatory Physiology follows a growing, and much-needed, trend by journals. Understandably, there is concern over how to do this without adding considerable work, especially if one's primary research focus is not on elucidating sex/gender differences. The purpose of this article is to provide additional guidance and examples on how to incorporate SABV into the conduct and reporting of basic and clinical research. Using examples from our research, which includes both studies focused and not focused on sex/gender differences, we offer suggestions for how to incorporate SABV into basic and clinical research studies.

Background Recruitment of large numbers of study participants within a designated time frame for multi-site clinical research studies is a significant challenge faced by researchers. If a study does not manage to recruit targeted number of participants, it could have a significant impact on the statistical significance of the research. Purpose This paper highlights the challenges of recruitment for a large multi-site UK-based tuberculosis observational study ‘PREDICT’. Methods It uses a case study analysis from the research nurses perspective, and descriptive information retrieved from non-recruitment log forms to understand reasons for potential recruits not participating. Results Some of the main challenges to recruitment included patients not attending their clinic appointments, time required to obtain site-specific permissions and courier timings for blood sample collection. This paper also outlines key reasons for potential recruits who did not participate. Some of the common barriers to participation for non-recruited participants were work and family commitments, additional blood tests and language barriers. Conclusion Successful strategies which were implemented to overcome some of the challenges during the study are presented. This paper, therefore, aims to present the challenges faced, lessons learnt and successful strategies implemented to inform the planning of similar longitudinal studies of this scale in future.

In Japan, a law called the Clinical Trials Act went into being effective on April 1, 2018, and clinical research on human subjects conducted in Japan has been undergone major changes. Those other than clinical trials for marketing approval of drugs or medical devices are broadly classified into “specific clinical trials” and others, and regulations have been tightened for each. As a result, clinical interventional study was drastically reduced, and observational clinical study increased. For the observational clinical study, the two previous ethical guidelines were merged into the “Ethical Guidelines for Medical and Biological Research Involving Human Subjects,” which was enacted in March 2021. The observational clinical study is now subjected to these ethical guidelines. In addition, changes are planned for the Act on the Protection of Personal Information, which greatly affects data collection in clinical research. Clinical research in Japan must be conducted appropriately while adapting to these various changes in the external environment and legal framework. Adapting to these changes is not an easy task, as it requires increased financial and human resources for all stakeholders.

Anesthetic agents disrupt neurodevelopment in animal models, but evidence in humans is mixed. The morphologic and behavioral changes observed across many species predicted that deficits should be seen in humans, but identifying a phenotype of injury in children has been challenging. It is increasingly clear that in children, a brief or single early anesthetic exposure is not associated with deficits in a range of neurodevelopmental outcomes including broad measures of intelligence. Deficits in other domains including behavior, however, are more consistently reported in humans and also reflect findings from nonhuman primates. The possibility that behavioral deficits are a phenotype, as well as the entire concept of anesthetic neurotoxicity in children, remains a source of intense debate. The purpose of this report is to describe consensus and disagreement among experts, summarize preclinical and clinical evidence, suggest pathways for future clinical research, and compare studies of anesthetic agents to other suspected neurotoxins.
