OBJECTIVES To reassess the definition of a large macular hole, factors predicting hole closure and post-surgery visual recovery. DESIGN Database study of 1483 primary macular hole operations. Eligible operations were primary MH operations treated with a vitrectomy and a gas or air tamponade. Excluded were eyes with a history of retinal detachment, high myopia, previous vitrectomy or trauma. RESULTS A higher proportion of operations were performed in eyes from females (71.1%) who were 'on average' younger (p  less then  0.001), with slightly larger holes (p  less then  0.001) than male patients. Sulfur hexafluoride gas was generally used for smaller holes (p  less then  0.001). From 1253 operations with a known surgical outcome, successful hole closure was achieved in 1199 (96%) and influenced by smaller holes and complete ILM peeling (p  less then  0.001), but not post-surgery positioning (p = 0.072). A minimum linear diameter of ~500 μm marked the threshold where the success rate started to decline. From the 1056 successfully closed operations eligible for visual outcome analysis, visual success (defined as visual acuity of 0.30 or better logMAR) was achieved in 488 (46.2%) eyes. At the multivariate level, the factors predicting visual success were better pre-operative VA, smaller hole size, shorter duration of symptoms and the absence of AMD. Selleckchem RK 24466 CONCLUSIONS Females undergoing primary macular hole surgery tend to be younger and have larger holes than male patients. The definition of a large hole should be changed to around 500 μm, and patients should be operated on early to help achieve a good post-operative VA.Value in healthcare can be defined as providing the optimal outcome per health dollar spent. Improving the value of healthcare for patients and healthcare organizations requires an understanding and evaluation of the costs and benefits. Investing in quality improvement (QI) work can bring about financial results for healthcare organizations over time, have beneficial organizational effects, and improve outcomes for patients. This article continues a series of QI educational papers in the Journal of Perinatology, and reviews financial and economic measures used to create the business case for QI. Ultimately, the business case for QI is better defined as a business strategy for success.OBJECTIVES This study explored whether donor-milk supplementation increases breastfeeding exclusivity at 6 months of life. In 10/2015, we implemented donor milk for breastfed newborns who needed nutritional supplements for hypoglycemia, hyperbilirubinemia, and >8% weight loss at 40 h of life. STUDY DESIGN We conducted a retrospective chart review on 122 qualified neonates admitted to newborn nursery at University of Florida Jacksonville 4 months before donor-milk implementation and 6 months after. RESULTS 73 (60%) of the neonates received formula and 49 (40%) received donor milk. 39 (54%) in the formula group and 33 (46%) in the donor-milk group were surveyed after 6 months of life. Multivariate logistic regression showed that newborns who received donor milk had five times greater odds of being exclusively breastfed at 6 months of life. CONCLUSIONS Donor milk as feeding supplementation for newborns is associated with increased exclusive breastfeeding at 6 months of life.The revised 2017 European LeukemiaNet (ELN) recommendations for genetic risk stratification of acute myeloid leukemia have been widely adopted, but have not yet been validated in large cohorts of AML patients. We studied 1116 newly diagnosed AML patients (age range, 18-86 years) who had received induction chemotherapy. Among 771 patients not selected by genetics, the ELN-2017 classification re-assigned 26.5% of patients into a more favorable or, more commonly, a more adverse-risk group compared with the ELN-2010 recommendations. Forty percent of the cohort, and 51% of patients ≥60 years, were classified as adverse-risk by ELN-2017. In 599 patients less then 60 years, estimated 5-year overall survival (OS) was 64% for ELN-2017 favorable, 42% for intermediate-risk and 20% for adverse-risk patients. Among 517 patients aged ≥60 years, corresponding 5-year OS rates were 37, 16, and 6%. Patients with biallelic CEBPA mutations or inv(16) had particularly favorable outcomes, while patients with mutated TP53 and a complex karyotype had especially poor prognosis. DNMT3A mutations associated with inferior OS within each ELN-2017 risk group. Our results validate the prognostic significance of the revised ELN-2017 risk classification in AML patients receiving induction chemotherapy across a broad age range. Further refinement of the ELN-2017 risk classification is possible.Temperature-sensitive genic male sterility (TGMS) lines are widely used in the breeding of hybrid crops1,2, but by what means temperature as a general environmental factor reverses the fertility of different TGMS lines remains unknown. Here, we identified an Arabidopsis TGMS line named reversible male sterile (rvms) that is fertile at low temperature (17 °C) and encodes a GDSL lipase. Cytological observations and statistical analysis showed that low temperature slows pollen development. Further screening of restorers of rvms, as well as crossing with a slow-growth line at normal temperature (24 °C), demonstrate that slowing of development overcomes the defects of rvms microspores and allows them to develop into functional pollen. Several other Arabidopsis TGMS lines were identified, and their fertility was also restored by slowing of development. Given that male reproductive development is conserved3, we propose that slowing of development is a general mechanism applicable to the sterility-fertility conversion of TGMS lines from different plant species.Potassium (K) is an essential nutrient, but levels of the free K ions (K+) in soil are often limiting, imposing a constant stress on plants. We have discovered a calcium (Ca2+)-dependent signalling network, consisting of two calcineurin B-like (CBL) Ca2+ sensors and a quartet of CBL-interacting protein kinases (CIPKs), which plays a key role in plant response to K+ starvation. The mutant plants lacking two CBLs (CBL2 and CBL3) were severely stunted under low-K conditions. Interestingly, the cbl2 cbl3 mutant was normal in K+ uptake but impaired in K+ remobilization from vacuoles. Four CIPKs-CIPK3, 9, 23 and 26-were identified as partners of CBL2 and CBL3 that together regulate K+ homeostasis through activating vacuolar K+ efflux to the cytoplasm. The vacuolar two-pore K+ (TPK) channels were directly activated by the vacuolar CBL-CIPK modules in a Ca2+-dependent manner, presenting a mechanism for the activation of vacuolar K+ remobilization that plays an important role in plant adaptation to K+ deficiency.
