Backgroud: A huge amount of data about psychosocial issues of people with haemophilia (PwH) are available; however, these materials are fragmentary and largely outdated, failing to reflect the impact of current treatment strategies. Aim: Describing the influence of illness on psychosocial aspects of adult PwH (≥18 years) and caregivers of children with haemophilia (CPwH) without inhibitors, in Italy. Methods: Surveys (for adult PwH, CPwH and haemophilia specialists) were developed by a multidisciplinary working group and conducted from November 2019 to June 2020. Results: A total of 120 PwH without inhibitors and 79 CPwH completed the survey. Adult patients reported a significant impairment in many psychosocial aspects, including working activities, relations with family members and social relations. Caregivers generally reported better scores in all aspects of the survey. Mobility, Pain and Mental health domains of EQ‐5D were the most frequently impaired in both patients and caregivers, reducing the perceived quality of life. Genetic counselling was an important issue, 53% of CPwH declaring unawareness of their carrier status, as well as the psychological support offered by the reference center, 67.0% of respondents reporting that no psychological support was provided at the time of diagnosis communication. Conclusion: This study provides information about PwH's and CPwH's point of view in the current scenario of continuous innovations in haemophilia treatment and management furthermore, updated insights on psychosocial problems faced by patients and caregivers are reported.

The metric and the electromagnetic potential generated by a static, spherically symmetric charged massive object in any dimension are given by the Reissner-Nordström-Tangherlini solution. We derive the expansion of this solution up to third post-Minkowskian order by computing the classical contribution of scattering amplitudes describing the emission of either a graviton or a photon from a massive charged scalar field up to two loops. In four and five dimensions these amplitudes develop ultraviolet divergences that are cancelled by higher-derivative counterterms in a way that generalises what was recently shown to happen in the chargeless case. This renormalisation procedure produces logarithmic terms that match exactly those produced in the post-Minkowskian expansion of the classical solution in de Donder gauge. [ABSTRACT FROM AUTHOR]

Introduction: Haemophilia management and patients' quality of life significantly improved. However, data on current patients', caregivers' and clinicians' satisfaction and limitations of treatments and haemophilia management are limited. Aim: Assessing the management satisfaction and unmet needs from the perspective of Italian patients with haemophilia (PWH) without inhibitors (or caregivers if children) and of specialist physicians. Methods: Surveys (for patients≥18 years, caregivers of children and haemophilia specialists) were developed by a multidisciplinary working group and conducted from November 2019 to June 2020. Results: Among 275 participants, 120 (43.6%) were PWH without inhibitors, 79 (28.7%) caregivers and 37 (13.4%) clinicians. Patients and caregivers perceived a higher control of the disease compared to clinicians. However, more than 40% of patients and caregivers reported to feel significantly conditioned by the risk of bleeding during their daily life. PWH reported a 6‐month mean/median (range) of bleeds 2.3/.0 (0‐24) and caregivers 1.3/.0 (0‐16) in children. The treatment burden (frequency of administration) was not satisfactory for more than half adults and caregivers of children treated with prophylaxis. A good access to treatment, haemophilia centres and medical service was reported, with issues associated to the multidisciplinary approach and treatment at emergency department. Conclusions: This large national study provides an updated overview of haemophilia care in Italy from different points of views, highlighting positive aspects and unmet needs. This information can guide future interventions to improve haemophilia management and the assessment of impact of new treatment options. [ABSTRACT FROM AUTHOR]

Substantial paradigm shifts have been recently registered in metastatic renal cell carcinoma (mRCC), with combination therapies including immunotherapy showing unprecedented results. We performed number needed to treat (NNT) and number needed to harm (NNH) analyses to evaluate these approaches in mRCC. Clinical data of mRCC patients enrolled in four phase III trials were collected. The rates at 6, 12, 18, and 24 months for overall survival (OS), duration of response (DoR), and progression-free survival (PFS) were considered. At 6 months, the number of patients that should be treated to prevent one death with sunitinib was 20 for both pembrolizumab-lenvatinib or axitinib, 14 for nivolumab-cabozantinib, and 50 for nivolumab-ipilimumab. NNT was 100 (at 6 months) or >100 (at 12 and 18 months) for nivolumab-ipilimumab. The combinations reported peculiar and not superimposable safety profiles at the NNH analysis. Although our results should be interpreted with caution, the analysis provides useful insight into the increasingly compelling interpretation of clinical trials. Immune combinations present clinically meaningful differences in terms of efficacy, with some treatments reporting different results at the NNT and the NNH analyses. [ABSTRACT FROM AUTHOR]

The increased interest of consumers in probiotic foods requires a deeper knowledge on the possible interactions with drugs, because their pharmacological properties could be modified. In this context, these studies are relevant for drugs such as acenocoumarol, whose dosage must be controlled due to, among other factors, food-drug interactions. Acenocoumarol is an oral anticoagulant with a narrow therapeutic range. The aim of the present research is to evaluate, in vitro , the effect of bifidobacteria on acenocoumarol. The drug was incubated with Bifidobacterium bifidum CIDCA 5310 or Bifidobacterium adolescentis CIDCA 5317 in MRS broth at 37°C for 24 h in anaerobic conditions. The effect of incubation with sterilized spent culture supernatants (SSCS) was also evaluated. Analysis by RP-HPLC showed that both bifidobacterial strains reduced the area of the acenocoumarol peak and two new peaks were evidenced. In addition, a decrease in the intensity of the bands at 1650, 1390 and 1110/cm was observed in the FTIR spectroscopic determinations. Moreover, a new band appeared at 1720/cm. No effect on the drug was observed when incubation was performed with SSCS. The present study showed a significant change in the concentration of the anticoagulant after incubation with bifidobacteria and results are compatible with biomodification of the drug due to enzymatic activity of bifidobacteria.
