Abstract
PURPOSE To analyze the efficacy of liposomal ozonated oil (Ozonest®) treatment, in patients with blepharitis or blepharoconjunctivitis, in improving the signs and symptoms of the pathology. METHODS Exploratory, open-label, prospective, single-arm, pre-post comparative pilot study in usual clinical practice, in 20 patients with blepharitis/blepharoconjunctivitis, receiving treatment with liposomal ozonated oil, one drop in each eye, 4 times a day, for 28 days. Main purpose was to assess whether there was a clinically improvement in the blepharitis specific BLISS questionnaire score. Changes in the 12-item OSDI, in eyelid signs of blepharitis assessed by the physicians were also evaluated among other tests, and there was also a subjective evaluation of the treatment by patients. RESULTS The BLISS score significantly improved from 16.4 before treatment to 11.8 after treatment (p < 0.05). The OSDI score was also significantly improved from 27.5 before treatment to 20.5 after treatment (p < 0.05). All tests conducted before and after treatment showed significant improvement (p < 0.05), except for NIBUT. The treatment received a score of 7 out of 10 by the patients. There were no adverse events in any patient. CONCLUSION Liposomal ozonated oil treatment showed good efficacy in improving the signs and symptoms of blepharitis/blepharoconjunctivitis, satisfaction of patients, and good safety and tolerability.

Abstract
Adequate and balanced nutrition is essential to promote optimal child growth and a long and healthy life. After breastfeeding, the second step is the introduction of complementary feeding (CF), a process that typically covers the period from 6 to 24 months of age. This process is, however, still highly controversial, as it is heavily influenced by socio-cultural choices, as well as by the availability of specific local foods, by family traditions, and pediatrician beliefs. The Società Italiana di Pediatria Preventiva e Sociale (SIPPS) together with the Federazione Italiana Medici Pediatri (FIMP), the Società Italiana per lo Sviluppo e le Origine della Salute e delle Malattie (SIDOHaD), and the Società Italiana di Nutrizione Pediatrica (SINUPE) have developed evidence-based recommendations for CF, given the importance of nutrition in the first 1000 days of life in influencing even long-term health outcomes. This paper includes 38 recommendations, all of them strictly evidence-based and overall addressed to developed countries. The recommendations in question cover several topics such as the appropriate age for the introduction of CF, the most appropriate quantitative and qualitative modalities to be chosen, and the relationship between CF and the development of Non-Communicable Diseases (NCDs) later in life.

Abstract
Clustered regularly interspaced palindromic repeat (CRISPR) systems are revolutionizing many areas of biology and medicine, where they are increasingly utilized as therapeutic tools for correcting disease-causing mutations. From a clinical perspective, unintended off-target (OT) DNA double-strand break (DSB) induction by CRISPR nucleases represents a major concern. Therefore, in recent years considerable effort has been dedicated to developing methods for assessing the OT activity of CRISPR nucleases, which in turn can be used to guide engineering of nucleases with minimal OT activity. Here we describe a detailed protocol for quantifying OT DSBs genome-wide in cultured cells transfected with CRISPR enzymes, based on the breaks labeling in situ and sequencing (BLISS) method that we have previously developed. CRISPR-BLISS is versatile and scalable, and allows assessment of multiple guide RNAs in different cell types and time points following cell transfection or transduction.

Abstract
Human immunodeficiency virus type-1 (HIV-1) infection has resulted in the death of upward of 39 million people since being discovered in the early 1980s. A cure strategy for HIV-1 has eluded scientists, but gene editing technologies such as clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) offer a new approach to developing a cure for HIV infection. While the CRISPR/Cas9 system has been used successfully in a number of different types of studies, there remains a concern for off-target effects. This review details the different aspects of the Cas9 system and how they play a role in off-target events. In addition, this review describes the current technologies available for detecting off-target cleavage events and their advantages and disadvantages. While some studies have utilized whole genome sequencing (WGS), this method sacrifices depth of coverage for interrogating the whole genome. A number of different approaches have now been developed to take advantage of next generation sequencing (NGS) without sacrificing depth of coverage. This review highlights four widely used methods for detecting off-target events: (1) genome-wide unbiased identification of double-stranded break events enabled by sequencing (GUIDE-Seq), (2) discovery of in situ Cas off-targets and verification by sequencing (DISCOVER-Seq), (3) circularization for in vitro reporting of cleavage effects by sequencing (CIRCLE-Seq), and (4) breaks labeling in situ and sequencing (BLISS). Each of these technologies has advantages and disadvantages, but all center around capturing double-stranded break (DSB) events catalyzed by the Cas9 endonuclease. Being able to define off-target events is crucial for a gene therapy cure strategy for HIV-1.

Abstract
DNA double-strand breaks (DSBs) are deleterious and tumorigenic but could also be essential for DNA-based processes. Yet the landscape of physiological DSBs and their role and repair are still elusive. Here, we mapped DSBs at high resolution in cancer and non-tumorigenic cells and found a transcription-coupled repair mechanism at oncogenic super-enhancers. At these super-enhancers the transcription factor TEAD4, together with various transcription factors and co-factors, co-localizes with the repair factor RAD51 of the homologous recombination pathway. Depletion of TEAD4 or RAD51 increases DSBs at RAD51/TEAD4 common binding sites within super-enhancers and decreases expression of related genes, which are mostly oncogenes. Co-localization of RAD51 with transcription factors at super-enhancers occurs in various cell types, suggesting a broad phenomenon. Together, our findings uncover a coupling between transcription and repair mechanisms at oncogenic super-enhancers, to control the hyper-transcription of multiple cancer drivers. Physiological DSBs are enriched at highly active oncogenic super-enhancers (SEs) RAD51 co-localizes with transcription factors at SE in various cells TOP1 mediates DSBs at SEs that are repaired by a RAD51-dependent mechanism Depletion of RAD51 increases DSBs at SEs and decreases expression of related oncogenes.

Abstract
DNA double-strand breaks (DSBs) could be deleterious and lead to age-related diseases, such as cancer. Recent evidence, however, associates DSBs with vital cellular processes. As discussed here, genome-wide mapping of DSBs revealed an unforeseen coupling mechanism between transcription and DNA repair at super-enhancers, as means of hypertranscription of oncogenic drivers.

Abstract
DNA double-strand breaks (DSBs) are major DNA lesions that are constantly formed during physiological processes such as DNA replication, transcription, and recombination, or as a result of exogenous agents such as ionizing radiation, radiomimetic drugs, and genome editing nucleases. Unrepaired DSBs threaten genomic stability by leading to the formation of potentially oncogenic rearrangements such as translocations. In past few years, several methods based on next-generation sequencing (NGS) have been developed to study the genome-wide distribution of DSBs or their conversion to translocation events. We developed Breaks Labeling, Enrichment on Streptavidin, and Sequencing (BLESS), which was the first method for direct labeling of DSBs in situ followed by their genome-wide mapping at nucleotide resolution (Crosetto et al., Nat Methods 10:361-365, 2013). Recently, we have further expanded the quantitative nature, applicability, and scalability of BLESS by developing Breaks Labeling In Situ and Sequencing (BLISS) (Yan et al., Nat Commun 8:15058, 2017). Here, we first present an overview of existing methods for genome-wide localization of DSBs, and then focus on the BLESS and BLISS methods, discussing different assay design options depending on the sample type and application.
