Inherited defects in the neuromuscular junction can lead to congenital myasthenia syndrome (CMS), a clinically and genetically heterogeneous group of disorders which includes fetal akinesia deformation sequence (FADS) on the severe end of the spectrum. Here, we report two unrelated families with biallelic CHRNB1 variants, and in each family, one child presented with lethal FADS. We contrast the diagnostic odysseys in the two families, one of which lasted 16 years while the other, utilizing rapid exome sequencing, led to specific treatment in the first 2 weeks of life. Furthermore, we note that CHRNB1 variants may be under-recognized because in both families, one of the variants is a single exon deletion that has been previously described but may not easily be detected in clinically available genetic testing.
Identifying crystalloids, which includes amylase and tyrosine crystalloids, is relatively uncommon in salivary gland fine-needle aspiration (FNA) cytology. Although it has been suggested that the presence of crystalloids favors a benign process, the full significance has not been well established.

The authors performed a review of slides from all salivary gland FNA cases received in their laboratory from January 2017 to September 2019 to identify cases with crystalloids (screened cohort). GNF-Pf-1127 In addition, the departmental archives were searched retrospectively for all salivary gland FNA cases that had specifically reported crystalloids. Cytologic findings as well as correlation with surgical pathology and clinical follow-up were examined.

There were 664 cases in the screened cohort. Crystalloids were present in 37 cases (incidence, 5.6%). Amylase crystalloids were the most commonly identified (n = 28; 75%), followed by tyrosine crystalloids (n = 4; 11%), and collagenous crystalloids (n = 1; 3%). Four cases with crystalloids could not be further classified because of low quantity (n = 4; 11%). An additional 54 cases were identified in the 10-year retrospective review. Diagnostic categorization for the total cohort (N = 91) was as follows nondiagnostic, 30 cases (33%); nonneoplastic/benign, 42 cases (46%); neoplasm benign, 10 cases (11%); and atypia of undetermined significance, 9 cases (10%). Twenty-six cases had subsequent resection findings, including oncocytic cyst/cystadenoma in 8 cases (31%), chronic sialadenitis/ductal obstructive change in 7 cases (27%), pleomorphic adenoma in 5 cases (27%), developmental cyst in 3 cases (12%), lymphoepithelial cyst in 2 cases (8%), and Warthin tumor in 1 case (4%).

This cohort represents the largest FNA series of salivary gland crystalloids. All cases were associated with nonneoplastic or benign neoplastic lesions.

However, the molecular and cellular mechanisms underlying the ability of cancer cells to metastasize remain relatively poorly understood. Among all solid tumors, small cell lung cancer (SCLC) has remarkable metastatic proclivity, with a majority of patients diagnosed with metastatic disease. Our understanding of SCLC metastasis has been hampered for many years by the paucity of material from primary tumors and metastases, as well as the lack of faithful pre-clinical models. Here, we review recent advances that are helping circumvent these limitations. These advances include methods that employ circulating tumor cells from the blood of SCLC patients and the development of diverse genetically engineered mouse models of metastatic SCLC. New insights into the cellular mechanisms of SCLC metastasis include observations of cell fate changes associated with increased metastatic ability. Ongoing studies on cell migration and organ tropism promise to expand our understanding of SCLC metastasis. Ultimately, a better molecular understanding of metastatic phenotypes may be translated into new therapeutic options to limit metastatic spread and treat metastatic SCLC.Genetic testing can provide definitive molecular diagnoses and guide clinical management decisions from preconception through adulthood. Innovative solutions for scaling clinical genomics services are necessary if they are to transition from a niche specialty to a routine part of patient care. The expertise of specialists, like genetic counselors and medical geneticists, has traditionally been relied upon to facilitate testing and follow-up, and while ideal, this approach is limited in its ability to integrate genetics into primary care. As individuals, payors, and providers increasingly realize the value of genetics in mainstream medicine, several implementation challenges need to be overcome. These include electronic health record integration, patient and provider education, tools to stay abreast of guidelines, and simplification of the test ordering process. Currently, no single platform offers a holistic view of genetic testing that streamlines the entire process across specialties that begins with identifying at-risk patients in mainstream care settings, providing pretest education, facilitating consent and test ordering, and following up as a "genetic companion" for ongoing management. We describe our vision for using software that includes clinical-grade chatbots and decision support tools, with direct access to genetic counselors and pharmacists within a modular, integrated, end-to-end testing journey.
Alzheimer's disease (AD) is the most prevalent form of dementia in the aging population; however, no effective therapy has been established. It has been previously demonstrated that daily intake of hydroxytyrosol (HT), a polyphenol in olive oil, at a daily dietary level mildly improves cognition in AD mice. In the present study, HT acetate (HT-ac), which is a natural derivative of HT in olive oil that exhibits better bioactivity than HT improves cognition.

HT-ac to APP/PS1 is orally administered to transgenic mice and used Aβ-treated neuronal cultures to explore the neuroprotective effects of HT-ac in preventing AD progression. It is found that HT-ac remarkably improved the escape latency, escape distance, and the number of platform crossings of AD mice in the water maze test by ameliorating neuronal apoptosis and decreasing inflammatory cytokine levels. It is further demonstrated that HT-ac stimulated the transcription of ERβ and enhanced neuronal viability and electrophysiological activity in primary neurons but that these beneficial effects of HT-ac are abolished upon ERβ deficiency.
