Laboratory Perspective on Racial Disparities in Sexually Transmitted Infections.

BACKGROUND: Rates of sexually transmitted infections (STI) have risen steadily in recent years, and racial and ethnic minorities have borne the disproportionate burden of STI increases in the United States. Historical inequities and social determinants of health are significant contributors to observed disparities and affect access to diagnostic testing for STI. CONTENT: Public health systems rely heavily on laboratory medicine professionals for diagnosis and reporting of STI. Therefore, it is imperative that clinicians and laboratory professionals be familiar with issues underlying disparities in STI incidence and barriers to reliable diagnostic testing. In this mini-review, we will summarize contributors to racial/ethnic disparity in STI, highlight current epidemiologic trends for gonorrhea, chlamydia, and syphilis, discuss policy issues that affect laboratory and public health funding, and identify specific analytic challenges for diagnostic laboratories. SUMMARY: Racial and ethnic disparities in STI in the US are striking and are due to complex interactions of myriad social determinants of health. Budgetary cuts for laboratory and public health services and competition for resources during the COVID-19 pandemic are major challenges. Laboratory professionals must be aware of these underlying issues and work to maximize efforts to ensure equitable access to diagnostic STI testing for all persons, particularly those most disproportionately burdened by STI.

Formative research to inform development of a new diagnostic for soil-transmitted helminths: Going beyond the laboratory to ensure access to a needed product.

Soil-transmitted helminths (STHs) affect more than 1.5 billion people. The global strategy to control STH infections requires periodic mass drug administration (MDA) based on prevalence among populations at risk determined by diagnostic testing. Widely used copromicroscopy methods to detect infection, however, have low sensitivity as the prevalence and intensity of STH infections decline with repeated MDA. More sensitive diagnostic tools are needed to inform program decision-making. Using an integrated product development process, PATH conducted qualitative and quantitative formative research to inform the design and development of a more sensitive test for STH infections. The research, grounded in a conceptual framework for ensuring access to health products, involved stakeholder analysis, key opinion leader interviews, observational site visits of ongoing STH surveillance programs, and market research including market sizing, costing and willingness-to-pay analyses. Stakeholder analysis identified key groups and proposed strategic engagement of stakeholders during product development. Interviews highlighted features, motivations and concerns that are important for guiding design and implementation of new STH diagnostics. Process mapping outlined current STH surveillance workflows in Kenya and the Philippines. Market sizing in 2016 was estimated around half a million tests for lower STH burden countries, and 1-2 million tests for higher STH burden countries. The cost of commodities per patient for a molecular STH diagnostic may be around $10, 3-4 times higher than copromicroscopy methods, though savings may be possible in time and staffing requirements. The market is highly price sensitive as even at $5 per test, only 27% of respondents thought the test would be used by surveillance programs. A largely subsidized STH control strategy and a semi-functional Kato-Katz test may have created few incentives for manufacturers to innovate in STH diagnostics. Diverse partnerships, as well as balancing needs and expectations for new STH diagnostics are necessary to ensure access to needed products.

Cooking a Research Project: New Trends in the Kitchen and in Scientific Policies.

The culture of chefs from the world's best restaurants is substituted by new trends paradigmatically epitomized by the TV program Masterchef. The authors feel that a similar transformation affects modern research. Recent scientific policies constrict the design of research grants with the aim of short-term maximization of the monetary value generated by the researcher.

Workload measurement for molecular genetics laboratory: A survey study.

Genetic testing availability in the health care system is rapidly increasing, along with the diffusion of next-generation sequencing (NGS) into diagnostics. These issues make imperative the knowledge-drive optimization of testing in the clinical setting. Time estimations of wet laboratory procedure in Italian molecular laboratories offering genetic diagnosis were evaluated to provide data suitable to adjust efficiency and optimize health policies and costs. A survey was undertaken by the Italian Society of Human Genetics (SIGU). Forty-two laboratories participated. For most molecular techniques, the most time-consuming steps are those requiring an intensive manual intervention or in which the human bias can affect the global process time-performances. For NGS, for which the study surveyed also the interpretation time, the latter represented the step that requiring longer times. We report the first survey describing the hands-on times requested for different molecular diagnostics procedures, including NGS. The analysis of this survey suggests the need of some improvements to optimize some analytical processes, such as the implementation of laboratory information management systems to minimize manual procedures in pre-analytical steps which may affect accuracy that represents the major challenge to be faced in the future setting of molecular genetics laboratory.

[Medical biology in the face of the evolution of health care needs]. / Rapport des Académies nationales de médecine et de pharmacie sur la biologie médicale La biologie médicale face aux défis de l'évolution des besoins de santé.

Since the publication of the ordinance of January 13th 2010, ratified by the law of May 30th 2013, medical biology in France has undergone a massive restructuration with the emergence of groups of several hundred laboratories. This evolution, which leads to a considerable reduction in the number of structures, causes numerous problems related to increased industrialization and financialization, difficulties of accreditation and disappearance of the proximity link between the biologist and the prescriber or the patient. It also leads to a clear disaffection of students, especially medical students, for this specialty whose medical character has been clearly affirmed by the law. This report takes stock of the current situation of medical biology and makes recommendations to strengthen the role of the medical biologist in the health system and patients' care.

Clinical pathologists and physician in France: which partnership and which future?

Medical biology is a major area of medical specialization in French health care system. It is going through massive changes in public as in private sector since the 2010 Ballereau edict with the merging of laboratories and new quality standards based on accreditation. We have suggested that physicians had a negative feeling about the restructuring of medical biology in recent years. An electronic questionnaire has been sent to physicians so as to find out what they thought about the evolution of medical biology and to get suggestions to improve the taking care of the patient. Have answered 1364 residents and physicians from all specializations, all regions, practicing in public or private hospitals or in general practices. Doctors have on the whole a negative feeling about how medical biology has evolved in recent years thinking that it is moving towards industrialization with delay increasing. They are convinced that tests must be made on site. They remain satisfied with the quality of the tests and have a positive feeling about scientific evolutions and are in favor of a better clinical-biological cooperation. The study points out a lack of clarity concerning how private laboratories are organized and how they operate. A computer link between clinical pathologists and physicians to access results and a list of urgent medical examinations could be set up so as to have a more rapid access to results. Rapid diagnostic tests or delocalized biology could be used but doctors do not want these tests to replace the clinical pathologist.

The future of laboratory medicine - a 2014 perspective.

Predicting the future is a difficult task. Not surprisingly, there are many examples and assumptions that have proved to be wrong. This review surveys the many predictions, beginning in 1887, about the future of laboratory medicine and its sub-specialties such as clinical chemistry and molecular pathology. It provides a commentary on the accuracy of the predictions and offers opinions on emerging technologies, economic factors and social developments that may play a role in shaping the future of laboratory medicine.
