Quantification of follicles in human ovarian tissue using image processing software and trained artificial intelligence†.

Cancer survival rates in prepubertal girls and young women have risen in recent decades due to increasingly efficient treatments. However, many such treatments are gonadotoxic, causing premature ovarian insufficiency, loss of fertility, and ovarian endocrine function. Implantation of donor ovarian tissue encapsulated in immune-isolating capsules is a promising method to restore physiological endocrine function without immunosuppression or risk of reintroducing cancer cells harbored by the tissue. The success of this approach is largely determined by follicle density in the implanted ovarian tissue, which is analyzed manually from histologic sections and necessitates specialized, time-consuming labor. To address this limitation, we developed a fully automated method to quantify follicle density that does not require additional coding. We first analyzed ovarian tissue from 12 human donors between 16 and 37 years old using semi-automated image processing with manual follicle annotation and then trained artificial intelligence program based on follicle identification and object classification. One operator manually analyzed 102 whole slide images from serial histologic sections. Of those, 77 images were assessed by a second manual operator, followed with an automated method utilizing artificial intelligence. Of the 1181 follicles the control operator counted, the comparison operator counted 1178, and the artificial intelligence counted 927 follicles with 80% of those being correctly identified as follicles. The three-stage artificial intelligence pipeline finished 33% faster than manual annotation. Collectively, this report supports the use of artificial intelligence and automation to select tissue donors and grafts with the greatest follicle density to ensure graft longevity for premature ovarian insufficiency treatment.

A systematic review of asthma and health literacy: a cultural-ethnic perspective in Canada.

BACKGROUND: Asthma is one of the most common inflammatory lung diseases and its prevalence and incidence have increased in many developed and developing countries. Asthma places a heavy burden on healthcare expenditures and productivity, which in turn diminishes the quality of life of the individuals involved as well as their families. The goal of improving a patient's knowledge about asthma management should include the enhancement of the individual's skills with the hopeful outcome of improving how the individual manages the condition. However, when health professionals prepare a training program, they are faced with the challenging cosmopolitan reality of individuals with different ethnic backgrounds. METHODS: In order to find links between asthma and health literacy in a cultural/ethnicity perspective, we performed a systematic review of all publications on the topic of asthma, health, and literacy among cultural groups from 1980 to 2006 using the Internet and journals: Medline (Ovid), ERIC, EMBASE, PsycINFO, Google, Google Scholar, Sociological Abstracts, and Anthropology Plus. Key words included the following: "asthma," "culture," "ethnicity," "literacy," "health," "health literacy," "health beliefs," "adults," "disease management," "chronic condition," "ethnocultural groups," "minority groups," and "newcomers/immigrants." RESULTS: More than 650 articles were initially identified in our review; 65 met our inclusion criteria. From these, we examined the factors related to asthma and literacy/health literacy with a cultural lens. All of these are categorized and summarized below. We chose what we considered to be the most relevant and important articles/documents in the research literature to date. Because many of the studies were qualitative, a formal meta-analytic review was not undertaken. We found that current asthma management techniques - including patient education - are not culturally sensitive, linguistically sensitive, or relevant, which creates further difficulties for ethnocultural communities and minority groups in many Western countries. In this systematic review, several themes were identified, including: approaches to language limitation and cultural barriers; the recognition of healthcare system bias (in terms of culturally competent care); and relationship-building to facilitate participatory decision-making by both provider and patient. This review provides further understanding and considerations regarding the beliefs and perspectives of care providers and populations in relation to health and illness, literacy and health literacy, and their association with asthma among ethnocultural communities. CONCLUSIONS: There is an urgent need to better define the impact of cultural and ethnic issues in the management of asthma in Canada. Appropriately designed studies should better define the barriers in the optimal delivery of asthma care influenced by these parameters.
