Prospects of testing late-time cosmology with weak lensing of gravitational waves and galaxy surveys

We investigate the synergy of upcoming galaxy surveys and gravitational wave (GW) experiments in constraining late-time cosmology, examining the cross-correlations between the weak lensing of gravitational waves (GW-WL) and the galaxy fields. Without focusing on any specific GW detector configuration, we benchmark the requirements for the high-precision measurement of cosmological parameters by considering several scenarios, varying the number of detected GW events and the uncertainty on the inference of the source luminosity distance and redshift. We focus on $\Lambda$CDM and scalar-tensor cosmologies, using the Effective Field Theory formalism as a unifying language. We find that, in some of the explored setups, GW-WL contributes to the galaxy signal by doubling the accuracy on non-$\Lambda$CDM parameters, allowing in the most favourable scenarios to reach even percent and sub-percent level bounds. Though the most extreme cases presented here are likely beyond the observational capabilities of currently planned individual GW detectors, we show nonetheless that - provided that enough statistics of events can be accumulated - GW-WL offers the potential to become a cosmological probe complementary to LSS surveys, particularly for those parameters that cannot be constrained by other GW probes such as standard sirens.Comment: 43 pages, 12 figure

Etnografia em uma "cidade em movimento": O evento Picnik e a ocupação do espaço público em Brasília

O artigo é uma reflexão sobre a economia criativa enquanto um fenômeno urbano, que emerge da interação constante e intensa entre indivíduos. Viver na cidade é participar de uma multiplicidade de hierarquias e de sistemas, de temporalidades e de situações, de agitações e de estímulos, que condicionam estilos de vida, conforme George Simmel (1987) descreve. Através de etnografia no evento Picnik, observamos de que forma a sociabilidade e a ocupação do espaço público brasiliense são favorecidas pela economia criativa.

Lung ultrasound in young children with neurological impairment: A proposed integrative clinical tool for deaeration-detection related to feeding

Infants and children with neurological impairment, such as cerebral palsy (CP), often experience abnormal ingestion functions, including oropharyngeal dysphagia and gastroesophageal reflux disease, which led to aspiration-related respiratory complications, morbidity, hospitalization, or death. There is a lack of evidence-based, repeatable, infant-friendly instrumental procedures to assess aspiration-risk in infants with CP or other neurological disorders, with also a lack of clinical assessment measures to support the use of more invasive diagnostic techniques. To this purpose, in the current study we explore the feasibility of lung ultrasound (LUS), to assess lung deaeration possibly related to aspiration during meal, in a cohort of 35 subjects affected by CP or other encephalopathies, and 10 controls in the same age-range. We coupled LUS procedure with meal caregiver administration for each child. Our results support the feasibility of this innovative approach in the clinical setting. Exploratory findings revealed a number of lung abnormalities likely related to abnormal ingestion function in subjects. Subgroup analyses revealed possible differences in LUS abnormalities between CP and other encephalopathies, possibly related to different mechanism of disease or dysfunction. Also, some evidences arose about the possible relationship between such LUS abnormalities and feeding and swallowing abilities in CP or other encephalopathies. LUS showed preliminarily feasibility and effectiveness in detecting meal-related LUS abnormalities in a dynamic manner in the clinical setting. This approach demonstrated usefulness as a potential tool for improving assessment and management in complex care of infants and young children with severe neurological disorders

Anemia in patients receiving anticancer treatments: focus on novel therapeutic approaches

Anemia is common in cancer patients and impacts on quality of life and prognosis. It is typically multifactorial, often involving different pathophysiological mechanisms, making treatment a difficult task. In patients undergoing active anticancer treatments like chemotherapy, decreased red blood cell (RBC) production due to myelosuppression generally predominates, but absolute or functional iron deficiency frequently coexists. Current treatments for chemotherapy-related anemia include blood transfusions, erythropoiesis-stimulating agents, and iron supplementation. Each option has limitations, and there is an urgent need for novel approaches. After decades of relative immobilism, several promising anti-anemic drugs are now entering the clinical scenario. Emerging novel classes of anti-anemic drugs recently introduced or in development for other types of anemia include activin receptor ligand traps, hypoxia-inducible factor-prolyl hydroxylase inhibitors, and hepcidin antagonists. Here, we discuss their possible role in the treatment of anemia observed in patients receiving anticancer therapies

Sexuality education in Italy 2016-2020: a national survey investigating coverage, content and evaluation of school-based educational activities

Comprehensive sexuality education is an important means of promoting sexual well-being amongst young people and is key to preventing sexually transmitted infections (STIs). However, sexuality education is not currently included in the formal curriculum in Italian schools. The aim of this study was to develop an inventory of schoolbased sexuality education (SBSE) activities carried out by external providers and implemented in Italy from 2016 to 2020. A desk review and survey were carried out. In the desk review online documents on STI prevention were analysed. The survey investigated the providers, objectives, content and methods used to implement SBSE activities in secondary schools. Findings revealed a highly heterogeneous situation in terms of geographical coverage, service providers, objectives and evaluation. Some SBSE activities were classified as adopting a comprehensive approach to sexuality education, while the majority focused on STI prevention, and many were single-session activities. Although most activities were said to have been evaluated no results were available. The data showed that SBSE is not systematically and equally delivered across Italy. Action is needed to provide young people with evidence-based, age-appropriate and accurate education about sexual and reproductive health and wellbeing

Musculoskeletal injuries among operating room nurses: results from a multicenter survey in Rome, Italy

Aim: Chronic disorders of the musculoskeletal system, particularly low back pain (LBP), are increasing and represent a social and economic problem of growing importance, especially if correlated with working conditions. Health care workers are at higher risk of developing LBP during work shifts in the hospital. The aim of this study was to assess the prevalence of LBP among operating room nurses and to investigate the risk factors for musculoskeletal injuries in the operating room. Methods: We carried out a cross-sectional study that included operating room nurses from nine hospitals. Information on sociodemographic characteristics, lifestyle habits, working activity and psychological attitude of nurses was collected using an anonymous self-administered structured questionnaire. We evaluated the association of frequency, localization and intensity of LBP (FLI) with qualitative variables, making use of univariate analysis, chi-square test and Fisher's exact test. Multiple logistic regression analysis was performed to identify the variables that affected the FLI. The covariates included in the model were the variables that had a p 35 years vs. age <35 (OR = 2.68; 95% CI = 1.17–6.18) and diurnal work shift vs. diurnal/ nocturnal (OR = 4.00; 95% CI = 1.72–9.0) represent risk factors associated with FLI, while physical activity is a protective factor (OR = 0.47; 95% CI = 0.20–1.08). Conclusion: The data suggest that it is important to promote new programs of prevention based on professional training and physical activity among nurses and to improve the organization of work shifts in the hospital

Innate Sensing of HIV-Infected Cells

Cell-free HIV-1 virions are poor stimulators of type I interferon (IFN) production. We examined here how HIV-infected cells are recognized by plasmacytoid dendritic cells (pDCs) and by other cells. We show that infected lymphocytes are more potent inducers of IFN than virions. There are target cell-type differences in the recognition of infected lymphocytes. In primary pDCs and pDC-like cells, recognition occurs in large part through TLR7, as demonstrated by the use of inhibitors and by TLR7 silencing. Donor cells expressing replication-defective viruses, carrying mutated reverse transcriptase, integrase or nucleocapsid proteins induced IFN production by target cells as potently as wild-type virus. In contrast, Env-deleted or fusion defective HIV-1 mutants were less efficient, suggesting that in addition to TLR7, cytoplasmic cellular sensors may also mediate sensing of infected cells. Furthermore, in a model of TLR7-negative cells, we demonstrate that the IRF3 pathway, through a process requiring access of incoming viral material to the cytoplasm, allows sensing of HIV-infected lymphocytes. Therefore, detection of HIV-infected lymphocytes occurs through both endosomal and cytoplasmic pathways. Characterization of the mechanisms of innate recognition of HIV-infected cells allows a better understanding of the pathogenic and exacerbated immunologic events associated with HIV infection
