Purpose In vitro fertilization with preimplantation genetic testing (IVF+PGT-M) reduces the risk of having a child affected by a heritable condition, yet only one-third of eligible patients are aware of this reproductive option. Access to education materials written at appropriate literacy levels could raise patients' awareness, but there is a mismatch between patient reading ability and the literacy demand of most materials. This study aimed to systematically identify written education materials on IVF+PGT-M and evaluate their literacy levels. We hypothesized that materials would fail to meet standards set by the Joint Commission and Centers for Disease Control and Prevention (CDC). Methods To identify patient education materials about IVF+PGT-M from academic databases and public-facing sources, an environmental scan was performed. Materials were analyzed using three validated scales Simple Measure of Gobbledygook, Patient Education Materials Assessment Tool, and Clear Communication Index. Results Seventeen patient education materials about IVF+PGT-M were identified from patient education databases, a consumer search engine, and professional organizations. The median reading level was 14.5 grade, median understandability was 74.2%, and median comprehensibility was 73.3%. Conclusions For most American adults, materials about IVF+PGT-M are not readable, understandable, or clear. The Joint Commission requires patient education materials be written at or below 5th grade reading level and the CDC recommends a 90% minimum score for comprehensibility. No evaluated material met these guidelines. Patient education materials that exceed average American literacy skills may perpetuate disparities in the utilization of IVF+PGT-M. Materials that communicate this complicated subject at an understandable level are needed.Purpose The objective of this systematic review and metaanalysis was to examine if the probability of pregnancy after ovarian stimulation for in vitro fertilization (IVF), using GnRH analogues and gonadotrophins is associated with serum estradiol level (Ε2) on the day of triggering final oocyte maturation with human chorionic gonadotrophin (hCG). Methods Twenty-one studies were eligible for this systematic review, including 19,598 IVF cycles, whereas three studies were eligible for metaanalysis, including 641 IVF cycles. The main outcome measure was achievement of ongoing pregnancy/live birth and, if not available, clinical pregnancy or biochemical pregnancy. Results Pooling of data showed no differences in the probability of clinical pregnancy between patients with high and low Ε2 levels on the day of triggering final oocyte maturation. The pooled effect sizes for the Ε2 thresholds groups constructed, regarding clinical pregnancy were 2000-3000 pg/mL-OR 0.91, 95% CI 0.55 to 1.50, (fair quality/moderate risk of bias, n = 1 study), 3000-4000 pg/mL-OR 0.89, 95% CI 0.46 to 1.70, (fair quality/moderate risk of bias, n = 1 study, good quality/no information on which to base a judgement about risk of bias n = 2 studies), 4000-5000 pg/mL-OR 0.74, 95% CI 0.37 to 1.49 fair quality/moderate risk of bias, n = 1 study), 5000-6000 pg/mL-OR 0.62, 95% CI 0.19 to 1.98, (fair quality/moderate risk of bias, n = 1 study). In addition, no difference was observed in the probability of ongoing pregnancy for the Ε2 threshold group of 3000-4000 pg/mL OR 0.85, 95% CI 0.40 to 1.81(good quality/no information on which to base a judgement about risk of bias, n = 1 study). Conclusion Currently, there is insufficient evidence to support or deny the presence of an association between the probability of pregnancy and serum Ε2 levels on the day of triggering final oocyte maturation with hCG in women undergoing ovarian stimulation for IVF.Protein secondary structure (PSS) describes the local folded structures which get formed inside a polypeptide due to interactions among atoms of the backbone. Generally, globular proteins are divided into four classes, namely all-α, all-β, α + β, and α/β. As nearly 90% of proteins fall into the said four classes, these are mostly considered for the purpose of computational classification of proteins. Classification of PSS is important for different biological functions that include protein fold recognition, tertiary structure prediction, prediction of DNA-binding sites, and reduction of the conformation search space among others. In this paper, we have proposed a machine learning-based model for secondary structure classification of proteins into four classes all-α, all-β, α + β, and α/β. In doing so, we have considered both sequence-based and structure-based features. At first, mutual information (MI), a filter-based feature selection method, is used to remove the redundant features, and then these selected odel for predicting the secondary structure of proteins based on its sequence-based and structure-based features. Graphical abstract.Purpose In breast cancer (BC), the duration of endocrine adjuvant therapies (AT) has been extended continuously up to 10 years. We present an alternative explanation for the effect, which could enable shorter treatments. Method The relevant literature on chemoprevention and (neo-)adjuvant therapy was reviewed. Data for initiation and growth of primary and contralateral BCs and their metastases (MET) were considered. Also, population-based data from the Munich Cancer Registry for MET-free survival, time trends of MET patterns, and survival achieved by improved ATs are used to estimate all events in the long-term follow-up. Results Extended ATs (EAT) that continue after 1, 2, or 5 years reduce mortality only slightly. AP26113 The effect is delayed, occurring more than 5 years after extension. EATs does not affect the prognosis of 1stBCs, they preventively eradicate contralateral 2ndBCs and thus their future life-threatening METs. Because chemoprevention can eradicate BCs from the smallest clusters to almost detectable BCs, ATs can be temporarily suspended without imposing harm. Results equal to EATs can be achieved by short-term ATs of the 1stBC and by repeated neo-ATs targeted at the indefinitely developing 2ndBCs. Considering this potential in de-escalation, a 70-80% reduction of overtreatment seems possible. Conclusion Knowledge of initiation and growth of tumors with known effects of neo-ATs suggest that intermittent endocrine ATs may achieve the same results as EATs but with improved quality of life and survival because of fewer side effects and better compliance. The challenge for developments of repeated ATs becomes how short is short enough.
