We are at the beginning of a genomic revolution in which all known species are planned to be sequenced. Accessing such data for comparative analyses is crucial in this new age of data-driven biology. Here, we introduce an improved version of DIAMOND that greatly exceeds previous search performances and harnesses supercomputing to perform tree-of-life scale protein alignments in hours, while matching the sensitivity of the gold standard BLASTP.Protein engineering has enormous academic and industrial potential. However, it is limited by the lack of experimental assays that are consistent with the design goal and sufficiently high throughput to find rare, enhanced variants. Here we introduce a machine learning-guided paradigm that can use as few as 24 functionally assayed mutant sequences to build an accurate virtual fitness landscape and screen ten million sequences via in silico directed evolution. As demonstrated in two dissimilar proteins, GFP from Aequorea victoria (avGFP) and E. coli strain TEM-1 β-lactamase, top candidates from a single round are diverse and as active as engineered mutants obtained from previous high-throughput efforts. By distilling information from natural protein sequence landscapes, our model learns a latent representation of 'unnaturalness', which helps to guide search away from nonfunctional sequence neighborhoods. Subsequent low-N supervision then identifies improvements to the activity of interest. In sum, our approach enables efficient use of resource-intensive high-fidelity assays without sacrificing throughput, and helps to accelerate engineered proteins into the fermenter, field and clinic.Treatments for Peyronie's Disease (PD) include oral medications, intralesional injections, and surgery. Collagenase Clostridium histolyticum (CCh) is the only FDA-approved treatment for PD. We sought to examine current trends in treatment of PD across the United States. Using data in the MarketScan Database, we conducted a retrospective study of men with PD in the United States. Cases were identified by ICD-9 and 10 codes, and treatments were identified using NDC and CPT codes. Treatment rates were analyzed using a linear regression model, and a Cox proportional hazard function test was performed for time-to-treatment analysis. About 27.8% of men with PD were treated within a year of diagnosis. The annual treatment rate increased from 23.2 to 35.4%, and intralesional injection was the most used treatment. Over the study period, the percentage of men receiving treatment with oral medication increased from 0.66 to 20.5%, while the use of intralesional injection and surgery decreased. Increased odds of treatment were observed in men 45-54 years (odds ratio [OR] 1.35; 95% confidence interval [CI], 1.21-1.50; p = 0) and in the southern region (OR 1.48; 95% CI, 1.39-1.56; p = 0). Trends in treatment of PD have changed over time. Intralesional injection remains the most used treatment option for men with PD.Topical anaesthetics are considered a first-line therapy option in men with premature ejaculation (PE). A cross-sectional retrospective analysis was performed to evaluate the real-life use of the eutectic mixture of prilocaine/lidocaine spray (FORTACIN™) in a cohort of 198 white-European men who had been consecutively and prospectively seen at a single tertiary-referral andrology centre for self-reported PE and naive for previous PE treatments. Descriptive statistics was used to describe the whole cohort and the paired t-test was applied to investigate potential differences throughout a 12-month follow-up (baseline, 1, 3, 6 and 12 months). Overall, mean (SD) age was 37 (6.5) years. Of all, lifelong, acquired and subjective PE were reported in 101 (51%), 59 (29.8%) and 38 (19.2%) patients at baseline, respectively. FORTACIN™ use increased up to 6 months, with 184 (92.9%) and 128 (66.4%) men who had tried and regularly used the compound, respectively. At 12-month follow-up, 53 (26.8%) men reported a regular use of the compound. Mean Premature Ejaculation Diagnostic Tool score significantly decreased at 6 and 12 months compared to baseline (all p  less then  0.05). Conversely, mean IELT significantly improved at 6-month follow-up compared to baseline (all p ≤ 0.04). Overall, FORTACIN™ emerged to be a safe and effective treatment option in PE patients of various types, with almost one fourth of patients still under treatment after 12 months. Timing and dosing of the drug can deserve to be adjusted according to patient's needs and their sexual ecology.

Older patients with colorectal cancer (CRC) experience chemotherapy dose reductions or discontinuation. Comprehensive geriatric assessment (CGA) predicts survival and chemotherapy completion in patients with cancer, but the benefit of geriatric interventions remains unexplored.

The GERICO study is a randomised Phase 3 trial including patients ≥70 years receiving adjuvant or first-line palliative chemotherapy for CRC. Vulnerable patients (G8 questionnaire ≤14 points) were randomised 11 to CGA-based interventions or standard care, along with guideline-based chemotherapy. The primary outcome was chemotherapy completion without dose reductions or delays. Secondary outcomes were toxicity, survival and quality of life (QoL).

Of 142 patients, 58% received adjuvant and 42% received first-line palliative chemotherapy. Interventions included medication changes (62%), nutritional therapy (51%) and physiotherapy (39%). More interventional patients completed scheduled chemotherapy compared with controls (45% vs. 28%, P = 0.0366). Severe toxicity occurred in 39% of controls and 28% of interventional patients (P = 0.156). QoL improved in interventional patients compared with controls with the decreased burden of illness (P = 0.048) and improved mobility (P = 0.008).

Geriatric interventions compared with standard care increased the number of older, vulnerable patients with CRC completing adjuvant chemotherapy, and may improve the burden of illness and mobility.

ClinicalTrials.gov ID NCT02748811.A recent study from Sun et al. https://www.selleckchem.com/products/sitagliptin.html reveals a polygenic architecture for pan-cancer tumour mutational burden (TMB) and shows the identification of genes underpinning the associations between germline genetic variants and TMB in specific cancer types. Here we discuss the main findings of the Sun et al. study and the implications for further studies.
