Sex disparities in efficacy in covid-19 vaccines: A systematic review and meta-analysis
Sex differences in adaptive and innate immune responses have been shown to occur and anecdotal reports suggest that vaccine efficacy and safety may be sex-dependent. We investigated the influence of sex on the efficacy of COVID-19 vaccines through a systematic review and meta-analysis of clinical trials on COVID-19 vaccines. The safety profile of COVID-19 vaccines was also investigated. A systematic review included eligible articles published in three databases and three websites. A meta-analysis of available data, stratified by sex, was conducted. Statistical analysis was performed using the Hartung\u2013Knapp\u2013Sidik\u2013Jonkman method, as well as influence and heterogeneity analysis. Pooled analysis showed significantly higher efficacy, measured as the rate of new COVID-19 cases, in men compared to women in the vaccine group (OR = 0.67, 95% CI 0.48\u20130.94). No sex differences were found in the rate of new cases in the control group (OR = 0.92, 95% CI 0.78\u20131.09). Safety profiles derived from pharmacovigilance reports appear to indicate increased toxicity in women. In conclusion, evidence of a potential role of sex in COVID-19 vaccine efficacy was described. It strengthens the need to include sex as a core variable in the clinical trial design of COVID-19 vaccines
FARMAPRICE: A Pharmacogenetic Clinical decision support system for precise and Cost-Effective Therapy
Pharmacogenetic (PGx) guidelines for the precise dosing and selection of drugs remain poorly implemented in current clinical practice. Among the barriers to the implementation process is the lack of clinical decision support system (CDSS) tools to aid health providers in managing PGx information in the clinical context. The present study aimed to describe the first Italian endeavor to develop a PGx CDSS, called FARMAPRICE. FARMAPRICE prototype was conceived for integration of patient molecular data into the clinical prescription process in the Italian Centro di Riferimento Oncologico (CRO)-Aviano Hospital. It was developed through a coordinated partnership between two high-tech companies active in the computerization of the Italian healthcare system. Introducing FARMAPRICE into the clinical setting can aid physicians in prescribing the most efficacious and cost-effective pharmacological therapy available
Autoimmunity and immunodeficiency associated with monoallelic LIG4 mutations via haploinsufficiency
BACKGROUND: Biallelic mutations in LIG4 encoding DNA-ligase 4 cause a rare immunodeficiency syndrome manifesting as infant-onset life-threatening and/or opportunistic infections, skeletal malformations, radiosensitivity and neoplasia. LIG4 is pivotal during DNA repair and during V(D)J recombination as it performs the final DNA-break sealing step.
OBJECTIVE: We explored whether monoallelic LIG4 missense mutations may underlie immunodeficiency and autoimmunity with autosomal dominant inheritance.
METHODS: Extensive flow-cytometric immune-phenotyping was performed. Rare variants of immune system genes were analyzed by whole exome sequencing. DNA repair functionality and T cell-intrinsic DNA damage tolerance was tested with an ensemble of in vitro and in silico tools. Antigen-receptor diversity and autoimmune features were characterized by high-throughput sequencing and autoantibody arrays. Reconstitution of wild-type vs. mutant LIG4 were performed in LIG4 knock-out Jurkat T cells and DNA damage tolerance was subsequently assessed.
RESULTS: A novel heterozygous LIG4 loss-of-function mutation (p.R580Q), associated with a dominantly inherited familial immune-dysregulation consisting of autoimmune cytopenias, and in the index patient with lymphoproliferation, agammaglobulinemia and adaptive immune cell infiltration into nonlymphoid organs. Immunophenotyping revealed reduced naïve CD4 T cells and low TCR-Vα7.2 T cells, while T/B-cell receptor repertoires showed only mild alterations. Cohort screening identified two other non-related patients with the monoallelic LIG4 mutation p.A842D recapitulating clinical and immune-phenotypic dysregulations observed in the index family and displaying T cell-intrinsic DNA damage intolerance. Reconstitution experiments and molecular dynamics simulations categorize both missense mutations as loss-of-function and haploinsufficient.
CONCLUSION: We provide evidence that certain monoallelic LIG4 mutations may cause human immune dysregulation via haploinsufficiency
The SIB Swiss Institute of Bioinformatics' resources: focus on curated databases
The SIB Swiss Institute of Bioinformatics (www.isb-sib.ch) provides world-class bioinformatics databases, software tools, services and training to the international life science community in academia and industry. These solutions allow life scientists to turn the exponentially growing amount of data into knowledge. Here, we provide an overview of SIB's resources and competence areas, with a strong focus on curated databases and SIB's most popular and widely used resources. In particular, SIB's Bioinformatics resource portal ExPASy features over 150 resources, including UniProtKB/Swiss-Prot, ENZYME, PROSITE, neXtProt, STRING, UniCarbKB, SugarBindDB, SwissRegulon, EPD, arrayMap, Bgee, SWISS-MODEL Repository, OMA, OrthoDB and other databases, which are briefly described in this article

Regolazione delle Reti Attive di Distribuzione mediante Approccio Spot Price
La continua crescita della potenza da Generazione
Distribuita (GD) connessa alle tradizionali reti
radiali in Media Tensione (MT) costringe inevitabilmente
autoritĂ regolatoria e distributori ad affrontare alcuni nuovi
problemi di natura tecnica, gestionale e commerciale, con
l’intento di trovarvi soluzione in tempi ridotti, onde evitare
pesanti limitazioni alla diffusione degli impianti di GD. Si
concretizza dunque l’esigenza di adottare architetture di
controllo, canali di comunicazione e strumenti di mercato
innovativi, in grado di coordinare l’esercizio e la gestione
della rete di distribuzione.
Questo lavoro presenta un nuovo scenario in cui la teoria
dei prezzi nodali viene applicata alla rete di distribuzione. Un
segnale di prezzo, calcolato a ciascun nodo, sia per l’energia
attiva che reattiva, può essere una soluzione efficace ai problemi
che potrebbero derivare da una elevata penetrazione
della GD, nel rispetto dei vincoli operativi della rete di
distribuzione
