Health, Patents, And Path Dependence: India's Pharmaceutical Crossroads, Jacie Bissell

Michigan Technology Law Review

This paper examines how India’s historical commitment to affordable medicine and public health continues to shape its pharmaceutical patent regime, even as the country aspires to become an innovation-driven economy. Through the lens of path dependence, the paper explores how India’s legal and institutional frameworks have created structural constraints on policy reform. Focusing on key moments such as the Patents Act of 1970, the landmark Novartis decision, and India’s evolving stance on the TRIPS waiver during the COVID-19 pandemic, the paper analyzes the tensions between fostering pharmaceutical innovation and maintaining access to affordable medicines. While recent procedural reforms and judicial …

Regulating For Birth Justice, Jamille Fields Allsbrook

Lewis & Clark Law Review

Impacted persons have shared accounts of traumatic birthing experiences, and advocates have raised the alarm on the urgent need to advance birth justice. Despite this raised awareness, women and birthing people are still dying and suffering unnecessarily. Even more, systems are still structured to impede birthing choices, particularly those from marginalized communities such as Black and Indigenous women. Notably, over 80% of U.S. maternal deaths are preventable, according to federal government data. Ironically, the same laws and systems that have created, perpetuated, and tolerated birth injustices can be leveraged to move the country towards birth justice. On the national level, …

Professional Identity Development Among Nursing Students: The Impact Of Structured Reflective Practice, Abdelmonim El Fadely, Kamal Takhdat, Charaf-Eddine Ahraiba, Rahma Bouali, Sabah Selmaoui, Boujemaa Agorram

Health Professions Education

Purpose This study aimed to assess the impact of a structured reflective practice intervention on the development of professional identity among nursing students. Method A mixed-methods design was adopted. The intervention, based on guided reflective practice, was implemented with a voluntary sample of 58 participants. The evaluation relied on a quasi-experimental quantitative approach using the Macleod Clark Professional Identity Scale, with a comparison group and both pre-test and post-test measurements. A qualitative component was also included to explore the dimensions of the studied concept in greater depth. Results Quantitative findings showed a statistically significant difference between the post-test means (p < 0.001), indicating that the reflective practice intervention had a positive effect on the experimental group compared to the control group. The qualitative results further illuminated students’ reflections, which were organized into ten themes corresponding to the study’s conceptual framework: professional knowledge and skills, values and ethics, the nursing role, leadership, professional self-image, social image of the profession, sense of belonging, identification with role models, theory–practice integration, and career choice. These dimensions provided a comprehensive and nuanced understanding of professional identity, capturing the complexity of the concept. Conclusion These results support the integration of reflective practice as a pedagogical approach to fostering the construction and development of a positive professional identity. Professional identity, as a rich and multidimensional concept, goes beyond the process of professionalization—it represents its ultimate achievement.

Developing A Framework To Enhance Medical Student Well-Being: A Cross-Sectional Study Exploring The Interplay Between Stress, Resilience, And Quality Of Life, Omayma Hamed, Elshaimaa Ahmed, Lamiaa Mohsen, Patricia S. Sexton

Health Professions Education

Purpose: Medical training imposes significant stress on students, often leading to burnout, anxiety, and/or diminished quality of life (QoL). Resilience has been identified as a critical factor in mitigating these challenges. However, there is limited research examining how stress and resilience interact to shape QoL in undergraduate medical students. This study expands upon Lazarus and Folkman’s Transactional Model of Stress and Coping by introducing a synthesized framework that integrates resilience as both a mediator and moderator of stress, advancing the understanding of these relationships.

Methods: A cross-sectional study was conducted among 194 first- and second-year medical students at a private …

From State House To World Health Assembly: The Distinct Missions Of National And International Leadership In Oral Healthcare, Robert A. Faiella Dmd, Mmsc., Mba, William R. Calnon Dds, Facd

Journal of the American College of Dentists

Leadership in oral healthcare has long been treated as a skill assimilated over time through experience rather than intentionally defined, taught, and assessed. Unlike clinical practice, education, research, and infection control, leadership in oral healthcare lacks consistent standards despite its critical role in integrating these systems and guiding the profession’s future. As healthcare becomes increasingly collaborative and global, dentistry must deliberately develop leadership capabilities at multiple levels. This article examines leadership at the national and international levels, using the American Dental Association’s role within U.S. and global health and dental organizations as examples. It explores why these leadership contexts require …

What Is A Standard? Perspectives On Acd’S Standards For Leadership In Oral Healthcare, N. Karl Haden Phd, Facd

Journal of the American College of Dentists

The American College of Dentists’ new Standards for Leadership in Oral Healthcare mark the first attempt in dentistry to articulate standards specifically for leadership, complementing the broader orientation offered by the Ethics Handbook for Dentistry. This article explores the basic question, “What is a standard?” Close reading of the document indicates at least three distinct but related senses of the term: an expectation, a norm, and a guiding principle. The article offers an interpretation of how these three senses fit together coherently. Referencing the Handbook, the article argues that the leadership standards are most impactful only when habituated, when practiced …

Journal of the American College of Dentists

This special issue of the Journal of the American College of Dentists responds to a growing but long-underrecognized demand for humanities and ethics in dental education, practice, and scholarship. It emerges from the work of the National Collaborative on Humanities and Ethics in Dentistry (NCHED), a multi-institutional partnership formed in 2023 to address the persistent exclusion of dentistry from broader health humanities conversations. Through national webinars and scholarly collaboration, NCHED has demonstrated substantial interest in ethical reflection, historical analysis, narrative inquiry, and the arts as essential to understanding oral health and dental care.
