BACKGROUND AND AIMS Intraspecific variation in foundation species of forest ecosystems can shape community and ecosystem properties, particularly when that variation has a genetic basis. Traits mediating interactions with other species are predicted by simple allocation models to follow ontogenetic patterns that are rarely studied in trees. The aim of this research was to identify the roles of genotype, ontogeny and genotypic trade-offs shaping growth, defence, and reproduction in aspen. METHODS We established a common garden replicating over 500 aspen genets in Wisconsin, USA. Trees were measured through the juvenile period into the onset of reproduction, for growth, defence chemistry (phenolic glycosides, condensed tannins), nitrogen, extrafloral nectaries, leaf morphology (specific leaf area), flower production, and foliar herbivory and disease. We also assayed the TOZ19 sex marker and heterozygosity at 10 microsatellite loci. KEY RESULTS We found high levels of genotypic variation for all traits, and highoad range and diverse community of associates and in turn further fosters that diversity. © The Author(s) 2020.

It is unclear if they also affect patient's immune recovery (IR) in combined antiretroviral therapy (cART). METHODS We conducted cohort study on 853 patients under cART for evaluating the impacts of viral factor on host IR. We used Generalized Estimating Equations for factor affecting CD4 recovery, Kaplan-Meier curves for the probability achieving IR and Cox hazard model for factors influencing the rate of IR. RESULTS In addition to low baseline CD4 and old age, CRF01_AE and its cluster 4 independently associated with lower CD4 cell recovery (P≤0.003), slower rate of IR (P≤0.022), less patients (P less then 0.001) and longer time achieving IR (P less then 0.001), compared to CRF07_BC and CRF01_AE cluster 5 respectively. Higher percentage of X4 viruses was found in CRF01_AE and cluster 4 infected patients (P less then 0.001), compared to their respective counterparts. The X4 viruses accounted for the poor IR in patients infected by CRF01_AE (P less then 0.001), its cluster 4 (P less then 0.001) and 5 (P≤0.029). Finally, we revealed that greater X4-binding propensity amino acids was exhibited in CRF01_AE clade (P less then 0.001) and CRF01_AE cluster 4 (P≤0.004). CONCLUSIONS Our study demonstrates that CRF01_AE clade and its cluster 4 are associated with poor IR in Chinese patients under cART, which are ascribed to high proportion of viruses with X4 tropism. MASM7 order HIV-1 genotyping and phenotyping should be used as surveillance tool for patients initiating cART. CCR5 inhibitors should be used with caution in regions with high prevalence of X4 viruses. © The Author(s) 2020. Published by Oxford University Press for the Infectious Diseases Society of America.

Cholesterol requests at pathology services provide an opportunity to improve uptake by integrating absolute CVD risk assessment with this service. OBJECTIVE This study aimed to assess the feasibility of such an additional service. METHODS Two-hundred and ninety-nine patients (45-74 years) referred to pathology services for blood cholesterol had measurement of all variables required to determine absolute CVD risk according to Framingham calculator (blood pressure, age, sex, smoking and diabetes status via self-report). Data were recorded via computer-based application. The absolute risk score was communicated via the report sent to the referring medical practitioner as per usual practice. Evaluation questionnaires were completed immediately post visit and at 1-, 3- and 6-month follow-up via telephone (n = 262). RESULTS Absolute CVD risk reports were issued for 90% of patients. Most patients (95%) reported that the length of time for the pathology service assessment was acceptable, and 91% that the self-directed computer-based application was easy to use. Seventy-eight per cent reported a preference for pathology services to conduct absolute CVD risk assessment. Only 2% preferred a medical practitioner. Of follow-up patients, 202 (75%) had a consultation with a medical practitioner, during which, aspects of CVD risk prevention were discussed (cholesterol and blood pressure 74% and 69% of the time, respectively). CONCLUSIONS Measurement of absolute CVD risk in pathology services is feasible, highly acceptable among middle-to-older adults and may increase uptake of guideline-directed care in general practice. © The Author(s) 2020.

The few trials which allow their inclusion focus on post-exposure prophylaxis or outpatient treatment of milder disease, limiting the options available to pregnant women with severe COVID-19 to compassionate use of remdesivir, or off-label drug use of hydroxychloroquine or other therapies. These restrictions were put in place despite experience with these drugs in pregnant women. In this Viewpoint, we call attention to the need and urgency to engage pregnant women in COVID-19 treatment trials now in order to develop data-driven recommendations regarding the risks and benefits of therapies in this unique but not uncommon population. © The Author(s) 2020.
