In grape cell cultures cv. Gamay Fréaux var. Teinturier, Ca was shown to decrease cell pigmentation through the inhibition of anthocyanin biosynthesis, while stimulating stilbenoids accumulation. Because methyl jasmonate (MeJA) is a well-known inducer of secondary metabolism in grape cells, and Ca antagonizes its stimulatory effect over several enzymes of core metabolic branches, in the present study we hypothesized that Ca and MeJA signaling pathways interact to regulate specific secondary metabolism routes. Grape cultured cells were elicited with MeJA or with MeJA + Ca and an UPLC-MS-based targeted metabolomic method was implemented to characterize their polyphenolic profiles. Results were compared with the profile of cells elicited with Ca only, previously reported. Data was complemented with gene expression analysis, allowing the assembly of a metabolic map that unraveled routes specifically regulated by both elicitors. MeJA + Ca specifically boosted E-resveratrol and E-ε-viniferin levels by 180% and 140%, respectively, in comparison to cells treated with MeJA only, while the stimulatory effect of MeJA over flavonoid synthesis was inhibited by Ca. In parallel, Ca downregulated most flavonoid pathway genes, including LAR1, ANS, BAN and ANR. Ca was able to mimic or potentiate the effect of MeJA on the expression of JA signaling genes, including JAR1, PIN and PR10. Transcript/metabolite correlation networks exposed the central influence of FLS1,STS,CDPK17 and COI1 in polyphenolic biosynthetic routes. This study highlights the potential of the MeJA-Ca combination for diverting polyphenolic metabolism towards the production of specific metabolites of interest, highly relevant in a biotechnological perspective.Non-invasive respiratory support (NRS) outside of the ICU has played an important role in the management of COVID-19 pneumonia. There is little data to guide selection of NRS modality. We present outcomes of NRS outside the ICU and discuss the effects of NRS on gas exchange with implications for management.
The ability to predict impending asthma exacerbations may allow better utilization of healthcare resources, prevention of hospitalization and improve patient outcomes. We aimed to develop models using machine learning to predict risk of exacerbations.
Data from 29,396 asthma patients was collected from electronic medical records and national registers covering clinical and epidemiological factors (e.g. comorbidities, health care contacts), between 2000 and 2013. Machine-learning classifiers were used to create models to predict exacerbations within the next 15 days. Model selection was done using the mean cross validation score of area under precision-recall curve (AUPRC).
The most important predictors of exacerbation were comorbidity burden and previous exacerbations. Model validation on test data yielded an AUPRC=0.007 (95% CI ± 0.0002), indicating that historic clinical information alone may not be sufficient to predict a near future risk of asthma exacerbation.
Supplementation with additional data on environmental triggers, (e.g. weather, pollen count, air quality) and from wearables, might be necessary to improve performance of the short-term predictive model to develop a more clinically useful tool.

COVID-19 was first diagnosed in Kenya in March 2020 following which the government instituted control measures which could have affected people's sexual satisfaction and overall quality of life including restrictions in travels; ban on alcohol consumption and closure of bars; 9 pm to 5 am curfew; ban on political rallies, and closure of many workplaces with people being encouraged to work from home.
The objective of this study was to determine how perceived and experienced sexual satisfaction changed with the advent of COVID-19 among heterosexual married individuals in Kenya.
The study was a cross-sectional survey. Data was collected virtually using monkey survey from social groups. A total of 194 participants responded to the survey.
The difference in overall sexual satisfaction as well as satisfaction with sex frequency; sex process; and time, place and ambience around sexual intercourse before and during COVID-19.
Most of the participants (73.4%) reported that they were satisfied with their marit19 and Its Control Measures on Sexual Satisfaction Among Married Couples in Kenya. Sex Med 2021;9100354.
There was perceived increase in dissatisfaction with sex which could be a pointer to the falling quality of life during COVID-19 pandemic especially among the most sexually active men aged 31-50 years living in places where COVID-19 control measures are being stringently implemented.

Atypical penile tunical lesions including isolated septal (ISS) and punctate scarring (PS) are an under recognized and difficult to treat subset of Peyronie's disease (PD) that often present with normal physical exams. Current guidelines provide little direction in the treatment of these men.
To review the results of our treatment approach in men with ISS and PS.
Data from all men undergoing duplex ultrasonography for either Peyronie's disease and/or erectile dysfunction over a 3-year period were reviewed. All men with ISS or PS and normal physical exams were included. WZ811 mouse First- and second-line treatment preferences and satisfaction with treatment in men with ISS and PS were retrospectively reviewed. Logistic regression was used to investigate associations between scar features and treatment preference MAIN OUTCOME MEASURES Treatment preference patterns, treatment satisfaction.
A total of 217 men with ISS and 197 men with PS were identified. Of these, 71 ISS and 86 PS patients had normal physical exams. l guidance in order to best manage men with atypical PD in the absence of societal guidelines and high-quality studies. This series provides guidance to clinicians on the management of these men, suggesting that conservative therapy and education may be sufficient. A standardized approach of increasing invasiveness showed reasonable rates of satisfaction with minimally invasive therapies playing a prominent role.
