Improving identification of lynch syndrome patients: A comparison of research data with clinical records
Current evidence suggests poor identification and referral of Lynch syndrome patients. This study evaluated the strategies by which patients with endometrial cancer were referred to genetics services. Data from clinic-based patients with endometrial cancer enrolled through the Australian National Endometrial Cancer population-based research study with detailed family history information were analyzed. The Amsterdam II criteria, the revised Bethesda guidelines, and criteria adapted for this study was assessed using personal/family history information. The percentages of patients referred and who could have been referred to genetics services, and the performance of each criterion for identifying possible mismatch-repair (MMR) gene mutation carriers, based on tumor MMR immunohistochemistry (IHC), were determined. Research data indicated that 236/397(59%) of patients with endometrial cancer had family/personal history of cancer, including 14 (4%) who fulfilled Amsterdam II criteria. Family history information was noted in the hospital records for only 61(15%) patients, including 7/14 (50%) of patients meeting Amsterdam criteria, and always less extensively than that recorded in the research setting. Only 13 patients (two meeting Amsterdam criteria) were referred for genetic assessment. Of 58 patients with tumor MMR protein-IHC loss, the Amsterdam criteria and Bethesda guidelines identified only three and 34% of these possible germline mutation carriers, respectively. Greater sensitivity (60%) was obtained using a single criterion proposed by our study, 2 first-degree or second-degree relatives reporting Lynch cancers. Hospital records indicate poor recognition of family history. Application of research methods show improved identification and may facilitate appropriate referrals of endometrial cancer patients with possible Lynch syndrome

Caryospora-like Coccidia infecting green turtles (Chelonia mydas): an emerging disease with evidence of interoceanic dissemination
Protozoa morphologically consistent with Caryospora sp. are one of the few pathogens associated with episodic mass mortality events involving free-ranging sea turtles. Parasitism of green turtles (Chelonia mydas) by these coccidia and associated mortality was first reported in maricultured turtles in the Caribbean during the 1970s. Years later, epizootics affecting wild green turtles in Australia occurred in 1991 and 2014. The first clinical cases of Caryospora-like infections reported elsewhere in free-ranging turtles were from the southeastern US in 2012. Following these initial individual cases in this region, we documented an epizootic and mass mortality of green turtles along the Atlantic coast of southern Florida from November 2014 through April 2015 and continued to detect additional, sporadic cases in the southeastern US in subsequent years. No cases of coccidial disease were recorded in the southeastern US prior to 2012 despite clinical evaluation and necropsy of stranded sea turtles in this region since the 1980s, suggesting that the frequency of clinical coccidiosis has increased here. Moreover, we also recorded the first stranding associated with infection by a Caryospora-like organism in Hawai'i in 2018. To further characterize the coccidia, we sequenced part of the 18S ribosomal and mitochondrial cytochrome oxidase I genes of coccidia collected from 62 green turtles found in the southeastern US and from one green turtle found in Hawai'i. We also sequenced the ribosomal internal transcribed spacer regions from selected cases and compared all results with those obtained from Caryospora-like coccidia collected from green turtles found in Australia. Eight distinct genotypes were represented in green turtles from the southeastern US. One genotype predominated and was identical to that of coccidia collected from the green turtle found in Hawai'i. We also found a coccidian genotype in green turtles from Florida and Australia with identical 18S and mitochondrial sequences, and only slight inter-regional differences in the internal transcribed spacer 2. We found no evidence of geographical structuring based on phylogenetic analysis. Low genetic variability among the coccidia found in green turtle populations with minimal natural connectivity suggests recent interoceanic dissemination of these parasites, which could pose a risk to sea turtle populations
