This approach\u0000enables the answering of scientific questions that cannot be addressed using\u0000single data sources due to limited variables. The potential of linked data for\u0000health research is enormous, as it can enhance prevention, treatment, and\u0000population health policies. Due the sensitivity of health data, there are\u0000strict legal requirements to prevent potential misuse. However, these\u0000requirements also limit the use of health data for research, thereby hindering\u0000innovations in prevention and care. Also, comprehensive Record linkage in\u0000Germany is often challenging due to lacking unique personal identifiers or\u0000interoperable solutions. Rather, the need to protect data is often weighed\u0000against the importance of research aiming at healthcare enhancements: for\u0000instance, data protection officers may demand the informed consent of\u0000individual study participants for data linkage, even when this is not\u0000mandatory. Furthermore, legal frameworks may be interpreted differently on\u0000varying occasions. Given both, technical and legal challenges, record linkage\u0000for health research in Germany falls behind the standards of other European\u0000countries. To ensure successful record linkage, case-specific solutions must be\u0000developed, tested, and modified as necessary before implementation. This paper\u0000discusses limitations and possibilities of various data linkage approaches\u0000tailored to different use cases in compliance with the European General Data\u0000Protection Regulation. It further describes requirements for achieving a more\u0000research-friendly approach to linking health data records in Germany.\u0000Additionally, it provides recommendations to legislators. The objective of this\u0000work is to improve record linkage for health research in Germany.","PeriodicalId":501219,"journal":{"name":"arXiv - QuanBio - Other Quantitative Biology","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138741979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It sought to understand\u0000the effects of economic challenges on women's dietary choices and access to\u0000nutritious food across different socioeconomic groups. Using a mixed-methods\u0000approach, the research combined quantitative data from health and economic\u0000records with qualitative insights from interviews with diverse women. The study\u0000analyzed trends in nutritional health and economic factors before and after the\u0000pandemic and gathered personal accounts regarding nutrition and economic\u0000difficulties during this period. Findings showed a clear link between the\u0000economic downturn and deteriorating nutritional health, particularly in\u0000low-income and marginalized groups. These women reported decreased access to\u0000healthy foods and an increased dependence on less nutritious options due to\u0000budget constraints, leading to a decline in dietary quality. This trend was\u0000less evident in higher-income groups, highlighting stark disparities. The\u0000pandemic intensified pre-existing nutritional inequalities, with the most\u0000vulnerable groups facing greater adverse effects. However, community support\u0000and public health measures provided some relief. In summary, the pandemic's\u0000economic repercussions have indirectly impaired women's nutritional health,\u0000especially among the socioeconomically disadvantaged. This highlights the\u0000necessity for tailored nutritional interventions and economic policies focused\u0000on safeguarding women's health.","PeriodicalId":501219,"journal":{"name":"arXiv - QuanBio - Other Quantitative Biology","volume":"11 19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138538615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current practices for describing these\u0000relationships, such as drawing diagrams or graphs in a somewhat arbitrary\u0000manner, limit our ability to integrate various aspects of the gene functions\u0000and view the genome holistically. To overcome these limitations, we need a more\u0000appropriate way to describe the intricate relationships between genes.\u0000Interestingly, category theory, an abstract field of mathematics seemingly\u0000unrelated to biology, has emerged as a powerful language for describing\u0000relations in general. We propose that category theory could provide a framework\u0000for unifying our knowledge of genes and their relationships. As a starting point, we construct a category of genes, with its morphisms\u0000abstracting various aspects of the relationships betweens genes. These\u0000relationships include, but not limited to, the order of genes on the\u0000chromosomes, the physical or genetic interactions, the signalling pathways, the\u0000gene ontology causal activity models (GO-CAM) and gene groups. Previously, they\u0000were encoded by miscellaneous networks or graphs, while our work unifies them\u0000in a consistent manner as a category. By doing so, we hope to view the\u0000relationships between genes systematically. In the long run, this paves a\u0000promising way for us to understand the fundamental principles that govern gene\u0000regulation and function.","PeriodicalId":501219,"journal":{"name":"arXiv - QuanBio - Other Quantitative Biology","volume":"142 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138538571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
