V.Six new polyketides aplojaveediins A-F (1-6) were isolated from the endophytic fungus Aplosporella javeedii associated with the host plant Orychophragmus violaceus (Brassicaceae). The structures of the new metabolites were elucidated by analysis of their NMR and MS data. Compound 1 exhibited antifungal activity against the hyphae form of Candida albicans strain ATCC 24433 in the agar plate diffusion assay and the microbroth dilution assay. The kinetic of killing of C. albicans cells for compound 1 was considerably faster than that of the positive control hygromycin B. Compounds 1 and 6 also exhibited moderate antibacterial activities against sensitive (ATCC 29213) and drug-resistant (ATCC 700699) strains of Staphylococcus aureus. BB-2516 clinical trial LEDs have specific wavelengths that can positively influence the production of microalga biomass and biomolecules of interest. Filling the gaps in the literature, this study evaluated the effect of different LED wavelengths and photoperiods on protein productivities and free amino acid (FAA) profile of Spirulina sp. LEB 18 cultures. The best protein productivity results were obtained in red and green LED cultures using integral and partial photoperiods, respectively. In these experiments, protein productivities increased 2 and 1.6 times, respectively, compared to the control culture using fluorescent light. Green LEDs in partial photoperiod provided also the highest concentrations of essential and non-essential FAA, about 1.8 and 2.3 times higher, respectively, than control cultures. LEDs showed to be a promising sustainable light source for increasing protein productivity and FAA concentration in Spirulina sp. LEB 18 cultures. BACKGROUND Left atrial appendage occlusion (LAAO) to prevent stroke in patients with atrial fibrillation has been evaluated in 2 randomized trials; post-approval clinical data are limited. OBJECTIVES The purpose of this study was to describe the National Cardiovascular Data Registry (NCDR) LAAO Registry and present patient, hospital, and physician characteristics and in-hospital adverse event rates for Watchman procedures in the United States during its first 3 years. METHODS The authors describe the LAAO Registry structure and governance, the outcome adjudication processes, and the data quality and collection processes. They characterize the patient population, performing hospitals, and in-hospital adverse event rates. RESULTS A total of 38,158 procedures from 495 hospitals performed by 1,318 physicians in the United States were included between January 2016 and December 2018. The mean patient age was 76.1 ± 8.1 years, the mean CHA2DS2-VASc (congestive heart failure, hypertension, 65 years of age and older, diabetes mellitus, previous stroke or transient ischemic attack, vascular disease, 65 to 74 years of age, female) score was 4.6 ± 1.5, and the mean HAS-BLED (hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, drugs/alcohol concomitantly) score was 3.0 ± 1.1. The median annual number of LAAO procedures performed for hospitals was 30 (interquartile range 18 to 44) and for physicians was 12 (interquartile range 8 to 20). Procedures were canceled or aborted in 7% of cases; among cases in which a device was deployed, 98.1% were implanted with 38,000 patients implanted with the device. Patients were generally older with more comorbidities than those enrolled in the pivotal trials; however, major in-hospital adverse event rates were lower than reported in those trials. Congenital myasthenic syndromes (CMS) associated with pathogenic variants in the DOK7 gene (DOK7-CMS) have phenotypic overlap with other neuromuscular disorders associated with limb-girdle muscular weakness (LGMW). Genetic analysis of the most common mutation (c.1124_1127dupTGCC) in DOK7 was performed in 34 patients with "unexplained" LGMW associated with non-specific changes in muscle biopsy. Of the 34 patients, one patient showed the DOK7 c.1124_1127dupTGCC variant in homozygousity. Our study estimates the minimum prevalence of undiagnosed DOK7-CMS to be 2.9% in southern Brazilian patients from our centre. Our data confirm that clinicians should look for DOK7-CMS patients when the clinical manifestation is an 'unexplained' LGMW, mainly if associated with non-specific changes in muscle biopsy. OBJECTIVE We sought to describe the maternal, fetal, and neonatal outcomes of primary hyperparathyroidism in a contemporary setting through a retrospective case series conducted in a tertiary referral centre focused on women diagnosed with primary hyperparathyroidism prior to conception, in the antepartum period, or within 6 weeks postpartum. METHODS A retrospective chart review was conducted and data were abstracted to case report forms. Summary statistics are reported. RESULTS From 2000 to 2017, 19 women (23 pregnancies) with primary hyperparathyroidism were identified. Most women (79%) were symptomatic at presentation, though often with non-specific manifestations. While 14% of pregnancies involved maternal/obstetric complications, fetal/neonatal complications were observed in 45%. Mild hypercalcemia was identified in 57% of women, with accompanying hypophosphatemia and hypomagnesemia in 46% and 36% of women, respectively. Surgical intervention was performed for 89% women, and no complications were encountered. Normal calcium levels achieved through treatment before conception did not fully eliminate adverse outcomes. CONCLUSION Rates of perinatal complications in our series are more reassuring than the ubiquitously quoted rates from small and dated studies. The diagnosis of primary hyperparathyroidism may be easily missed during pregnancy, owing to its non-specific presentation. A high index of suspicion and measurement of ionized calcium levels is encouraged, especially for patients with excessive nausea and vomiting, nephrolithiasis, atypical presentations of hypertensive disorders, or isolated polyhydramnios. Mild degrees of calcium derangement do not preclude adverse perinatal outcomes. Surgery appears to be safe, even in the third trimester. The attenuated rate of complications noted in our series may have been the result of the high proportion of surgery, though this will require verification via meta-analysis or future prospective work.
