Fiona’s FVII footprint

Factor VII deficiency is a rare inheritable bleeding disorder that can be challenging to manage. Blood activity levels do not correlate with bleeding risk, and prophylaxis is a more difficult treatment option than for people with haemophilia due to the short half-life of factor VII. Acute bleeding manifestations and long-term complications are similar to those associated with haemophilia. This case study illustrates the psychological and physical impact of severe factor VII deficiency on a woman with impaired mobility due to haemarthropathy who must retain her independence to provide care for her elderly parents. She self-manages her joint pain and bleeding risk, but her life is limited by the need to avoid injury and her reluctance to engage fully with health services

A multi-country snapshot study of pain in people with haemophilia

People with haemophilia (PwH) experience recurrent bleeds in weight-bearing joints. Optimal management for people with severe haemophilia involves prophylaxis with factor VIII or IX, which helps to reduce the risk of bleeds and joint damage. However, this is expensive and frequently not an option in economically developing countries, where on-demand treatment is more commonly used as bleeding occurs. PwH with moderate and mild haemophilia are also treated on demand. Pain from bleeds and arthropathy is common in PwH; it is recognised as a burden that impairs quality of life and can be challenging to manage

Do nurses have the switch factor?

Switching between clotting factor products is becoming increasingly common as product choice increases and financial pressure grows to choose the most cost-effective options. Guidance on carrying out the switch recommends a complex and long process that may benefit from being defined in a protocol. Haemophilia nurses may be responsible for managing product switches; anecdotal evidence suggests that clinical practice is variable

The state of oral health in patients with haemophilia in the Netherlands

Introduction: Previous studies show contradictory outcomes regarding dental, gingival and periodontal status in persons with haemophilia (PWH) compared to healthy controls. PWH may experience disease-specific barriers to access dental care due to their bleeding tendency, which may lead to delays in oral care and severe dental problems. Aim: To determine the current subjective and objective oral health status in adult PWH. Methods: Randomly selected PWH of the Erasmus MC Haemophilia Treatment Center (HTC), Rotterdam, the Netherlands, were invited to participate. Data was collected using the Oral Health Impact Profile (OHIP-14NL) and personal interviews. A dentist used the DMFT index, the Dutch Periodontal Screening index (DPSI), plaque and bleeding index to score the dental status. Results: Forty-eight adult PWH were included in this study, 20 mild, 15 moderate-severe and 13 severe haemophilia with a mean age of 44.7. PWH scored low on the OHIP-14 questionnaire (median total score 1.0; IQR.0–3.0), indicating a high self-rating oral health status. The number of bleeding events, bleeding- and plaque index score was not statistically significant between patients with mild, moderate or severe haemophilia. The mean number of decayed, missing, and filled teeth (DMFT-score) was significantly lower in the group of patients with severe haemophilia (median 2.0) compared to mild haemophilia (median 16.0) (p =.04). Twenty-five patients (52.1%) reported to have encountered bleeding problems during or after dental interventions during their lifetime. Conclusion: Dutch adult PWH A/B have good dental status and oral health status

Haemophilia specialist nurses’ perceptions of haemophilia B

Some clinicians believe that haemophilia B is associated with less bleeding than haemophilia A, yet there appears to be little difference in health-related outcomes. Current clinical practice reduces the risk of bleeds, making differences difficult to measure. We surveyed specialist haemophilia nurses to discern their opinions about the impact of haemophilia B compared to haemophilia A

Search for pair production of vector-like quarks in leptonic final states in proton-proton collisions at s \sqrt{s} = 13 TeV

A search is presented for vector-like $\mathrm{T}$ and $\mathrm{B}$ quark-antiquark pairs produced in proton-proton collisions at a center-of-mass energy of 13 TeV. Data were collected by the CMS experiment at the CERN LHC in 2016-2018, with an integrated luminosity of 138 fb$^{-1}$. Events are separated into single-lepton, same-sign charge dilepton, and multilepton channels. In the analysis of the single-lepton channel a multilayer neural network and jet identification techniques are employed to select signal events, while the same-sign dilepton and multilepton channels rely on the high-energy signature of the signal to distinguish it from standard model backgrounds. The data are consistent with standard model background predictions, and the production of vector-like quark pairs is excluded at 95% confidence level for $\mathrm{T}$ quark masses up to 1.54 TeV and $\mathrm{B}$ quark masses up to 1.56 TeV, depending on the branching fractions assumed, with maximal sensitivity to decay modes that include multiple top quarks. The limits obtained in this search are the strongest limits to date for $\mathrm{T} \overline{\mathrm{T}}$ production, excluding masses below 1.48 TeV for all decays to third generation quarks, and are the strongest limits to date for $\mathrm{B} \overline{\mathrm{B}}$ production with $\mathrm{B}$ quark decays to tW.A search is presented for vector-like T and B quark-antiquark pairs produced in proton-proton collisions at a center-of-mass energy of 13 TeV.
