Qualitative longitudinal research is a useful method for studying adolescent development, not least because the dimension of temporality in the analysis of longitudinal studies can help researchers understand the complexity of transitions during this unique and dynamic life stage. The Gender and Adolescence: Global Evidence programme is a multi-year cross-country longitudinal study of adolescents in low- and middle-income countries. This article presents the methodological opportunities and challenges involved in analyzing such datasets, and seeks to offer insights for researchers undertaking qualitative longitudinal research. To ensure that both breadth and depth of such data are accurately represented in the analysis, a range of analytical approaches can be used. In this article, we provide key examples of how this data has been analyzed across a cohort of adolescent participants, exploring changes both pre- and post-Covid-19 including interactions with critical health and education services, and within individual life histories, exploring individual adolescent trajectories over multiple time points. Furthermore, we highlight how including caregivers' and key informants' perspectives can enhance triangulation of results. We show the importance of using a range of different approaches when analyzing a qualitative longitudinal dataset. [ABSTRACT FROM AUTHOR]

Currently, biotechnological advances have surpassed the classical aims of medicine. Critical conceptual changes have impacted the medical construct of the doctor-patient relationship, such as a) the diversity of the concept of human nature; b) the concept of human corporeality; c) the subjective concept of autonomy, and d) the value of quality of life. A bioethical analysis of these concepts leads to understanding why current medicine could be heading towards an 'enhancement' or 'transhumanist' medicine. The conclusion shows that medicine accepts the application of biotechnology advances under the classical postulates focused on the health field and that it is necessary to deeply reflect on their application to provide improvements or new functions to healthy subjects.

Fresh and processed food products are rich in bioactive molecules, including polysaccharides, vitamins, carotenoids, peptides, antioxidants, phenolics, phytosterols, and novel lipids. Bioactive molecules in food could prevent several diseases (i.e., metabolic syndrome, cardiovascular diseases, cancer, etc.). Thus, consumer awareness is growing about the health-promoting impact of food bioactive molecules. Health claims are essential added-value features, wherein health-enhancing potential of bioactives depend on their chemical structure. On the other hand, the investigation of the structure-function relationship of food bioactive molecules is of importance. In this regard, Molecules is delighted to highlight the importance of food bioactive molecules and their effect on health. In this Special Issue of Molecules, researchers are invited to contribute original research and up-to-date reviews. [ABSTRACT FROM AUTHOR]

The quality of reporting of results of health studies has been the subject of several papers in the recent years. There are several guidelines published on the topic, but improvements have been very slow. Lehana Thebane and Noori Akhtar-Danesh provide advice on how to report the analysis methods used to describe data and determine the descriptive statistics to use, and the accuracy with which to report the results [ABSTRACT FROM AUTHOR]

Munsell et al; "Growth Performance of Holstein Dairy Calves Fed Distillers Grains," by M. Thomas et al; "Milk Production and Preganancy Rate of Dairy Cows in an In-Vitro Fertlization Embryo ransfer Program," by L. E. Rensink et al.

The ILSI/HESI Workshop on Alternatives to Carcinogenicity Testing aims to develop and apply new methods for assessment of potential carcinogenic risk to humans from various chemicals. The Workshop represents a major cooperative scientific effort. The long-term goals should be to greatly enhance the efficiency and reliability of such testing and to supplant, not just supplement, lifetime rodent bioassays. There are now well-established frameworks for risk assessment and risk management, putting risks into public health context and engaging stakeholders. The Lave-Omenn value-of-information model provides a useful way to assess the social costs and benefits of different strategies for testing large numbers of chemicals. [ABSTRACT FROM AUTHOR]
