RESUMO
INTRODUCTION: As a result of centralisation of haemophilia care to a limited number of intramural settings, many persons with haemophilia have to travel long distances to attend their haemophilia specialised treatment centre. However, regular physiotherapy treatment can be provided by primary care physiotherapists in the person's own region. Due to the rarity of the disease most primary care physiotherapists have limited experience with this population. This study aims to provide a clinical practice guideline for primary care physiotherapists working with persons with bleeding disorders. METHOD: A list of the most urgent key-questions was derived from a previous study. Literature was summarised using the grading of recommendations assessment, development, and evaluation (GRADE) evidence-to-decision framework. Recommendations were drafted based on four 90 min consensus meetings with expert physiotherapists. Recommendations were finalised after feedback and >80% consensus of all stakeholders (including PWH, physiotherapists, haematologists and the corresponding societies). RESULTS: A list of 82 recommendations was formulated to support primary care physiotherapists when treating a person with a bleeding disorder. These recommendations could be divided into 13 categories: two including recommendations on organisation of care, six on therapy for adult patients with bleeding disorders and five on therapy adaptations for paediatric care. Therapy recommendations included treatment after a joint- or muscle bleed, haemophilic arthropathy, chronic synovitis, non-haemophilia related conditions and orthopaedic surgery. CONCLUSION: An evidence-based practice guideline, based on current evidence from literature and clinical expertise, has been developed for primary care physiotherapists treating a person with haemophilia. To improve care, the recommendations should be implemented in daily practice.
RESUMO
AIM: For people with haemophilia A (PwHA), bleeding in the joints leads to joint damage and haemophilia-related arthropathy, impacting range of motion and life expectancy. Existing guidelines for managing haemophilia A support healthcare professionals (HCPs) and PwHA in their efforts to preserve joint health. However, such guidance should be reviewed, considering emerging evidence and consensus as presented in this manuscript. METHODS: Fifteen HCPs experienced in the management of PwHA in the UK participated in a three-round Delphi panel. Consensus was defined at ≥70% of panellists agreeing or disagreeing for Likert-scale questions, and ≥70% selecting the same option for multiple- or single-choice questions. Questions not reaching consensus were revised for the next round. RESULTS: 26.8% (11/41), 44.8% (13/29) and 93.3% (14/15) of statements reached consensus in Rounds 1, 2 and 3, respectively. HCPs agreed that prophylaxis should be offered to patients with a baseline factor VIII (FVIII) level of ≤5 IU/dL and that, where there is no treatment burden, the aim of prophylaxis should be to achieve a trough FVIII level ≥15 IU/dL and maintain a longer period with FVIII levels of ≥20-30 IU/dL to provide better bleed protection. The aspirational goal for PwHA is to prevent all joint bleeds, which may be achieved by maintaining normalised (50-150 IU/dL) FVIII levels. CONCLUSION: The panel of experts were largely aligned on approaches to preserving joint health in PwHA, and this consensus may help guide HCPs.

INTRODUCTION: Joint bleeds in haemophilia cause destruction of articular structures, impaired function and pain. Up to 70% of people with haemophilia (PWH) report chronic pain. Little is known about the pain experiences in PWH in the UK. AIM: To identify prevalence and perceptions of pain among PWH living in the UK. METHODS: A cross-sectional, non-interventional survey study conducted among PWH (all severities). The survey incorporated elements from validated tools (EQ-5D; EQ-VAS) and was distributed via participating treatment centres. RESULTS: Five hundred and ninety-nine PWH responded, 91% aged > 18. 81% used factor prophylactically or on demand. More pain was reported by those treated on demand versus prophylaxis particularly in those who reported daily pain. 65% reported 'problem joints' based on individual impact rather than medically defined 'target joints', 2/3 reported multiple joint issues. The ankle was most commonly affected. 59% reported frequent pain, with 56% aware of pain constantly or most of the time and were more likely to report less favourable EQ-5D or EQ-VAS scores (p < .001). Pain frequency/awareness was consistent across all severities. Most discussed pain with care teams, 31% only when asked; 25% did not discuss it. Pain discussions resulted in physiotherapy referral (63%) analgesia prescription (48%), and a minority specialist pain referral (9%). Most felt well supported with regard to their pain, but 70% reported learning to live with it. CONCLUSION: Pain affects PWH of all ages and severities even in a well-resourced country significantly impacting quality of life. Clinicians must be more aware of chronic pain in PWH. Biopsychosocial approaches to pain assessment and management are recommended.

INTRODUCTION: The "problem joint" (PJ) concept was developed to address patient-centric needs for a more holistic assessment of joint morbidity for people with haemophilia (PwH). AIM: To quantify the humanistic burden of PJs in PwH to further support validation of the PJ outcome measure. METHODS: Multivariable regression models evaluated the relationship between PJs and health-related quality of life (HRQoL, EQ-5D-5L) and overall work productivity loss (WPL) using data from the 'Cost of HaEmophilia: a Socioeconomic Survey' population studies (adults: CHESS II, CHESS US+; children/adolescents: CHESS-Paeds). Covariates included were haemophilia severity, age, comorbidities and education. RESULTS: The CHESS II sample included 292 and 134 PwH for HRQoL and WPL analyses, mean age 38.6 years (39% ≥1 PJ, 61% none). CHESS US+ included 345 and 239 PwH for HRQoL and WPL, mean age 35 years (43% ≥1 PJ, 57% none). CHESS-Paeds included 198 PwH aged 4-17 (HRQoL only), mean age 11.5 years (19% ≥1 PJ, 81% none). In CHESS II and CHESS US+, presence of PJs was associated with worse HRQoL (Both p < .001). Few CHESS-Paeds participants had PJs, with no significant correlation with HRQoL. In CHESS II, upper body PJs were significantly correlated to WPL (p < .05). In CHESS US+, having ≥1 PJ or upper and lower body PJs were significantly correlated to WPL (vs. none; both p < .05). CONCLUSION: This study has shown a meaningful burden of PJs on PwH, which should be considered in clinical and health policy assessments of joint health.

Haemophilia treatment has seen great advances in recent years with an accompanied reduced risk of physical activity (PA) related bleeds. Based on its known health benefits, people with haemophilia (PWH) are currently encouraged to regularly engage in PA. However, this may not always translate to increased levels of PA. In this narrative review we aim to provide a brief overview of what is currently understood regarding PA levels and influences for the three broad age groups of children and adolescents, adults and older adults. We also provide recommendations for members of the haemophilia team on important aspects related to promotion of PA in their clinical practice. We highlight that PA behaviour is multifactorial and that many PWH still have limited access to adequate care. Whilst some still face unique challenges to being more physically active, overall, the barriers and facilitators to activity are very similar to that of the general population.

Study models are frequently used in orthodontics and are a key part of both initial assessment and treatment planning. They are an important part of comprehensive orthodontic records; furthermore, study models are an essential diagnostic aid that can be studied in detail without the patient being present. We present a case of a 14-year-old boy with an abnormal palatal swelling detected by his specialist orthodontist after review of study models taken at the initial appointment. At the assessment alone, the significance of the abnormality was not recognised and without the help of study models, diagnosis and treatment of his fibrous dysplasia may have been significantly delayed.

PURPOSE: Approximately 35%-50% of people with haemophilia (PWH) report living with chronic musculoskeletal pain. Although exercise based rehabilitation is effective for pain in other arthritises, there are no published guidelines for management of chronic pain in PWH. This review aims to evaluate and appraise the current evidence of effectiveness of physiotherapy interventions on (a) pain intensity, (b) quality of life (QoL) and (c) function in PWH. METHODS: A systematic review of five databases AMED and CINAHL, EMBASE and MEDLINE and PEDro, as well as trial registries, grey literature and hand searching key journals was completed. Included studies were critically appraised and evaluated for risk of bias. The GRADE approach was used to rate the quality of the evidence. RESULTS: Nine trials consisting of 235 participants met the inclusion criteria. All studies had an overall risk of bias with low methodological quality. Meta-analysis was not possible due to heterogeneity across trials. Studies comparing a range of physiotherapy interventions against no intervention showed no clear beneficial effect on pain intensity or QoL. Only one study, investigating hydrotherapy or land-based exercise against control, showed positive effect for pain intensity, but rated very low on GRADE assessment. Studies comparing one physiotherapy intervention against another showed no clear benefit on pain intensity, QoL or function. LASER with exercise and hydrotherapy were shown to have some positive effects on pain intensity, but no clear benefit on function. CONCLUSIONS: At present, there is limited evidence for the use of physiotherapy interventions in addressing the issue of pain in PWH. Better designed trials with higher quality and explicit methodology along with user involvement are needed to assess the efficacy of any proposed intervention.

INTRODUCTION: European guidelines on the care of haemophilia recommend ready access to a range of services provided by a multidisciplinary team of specialists including physiotherapy. However, the scope of physiotherapy provided is unknown. METHODS: The Physiotherapists Committee of the European Association for Haemophilia and Allied Disorders (EAHAD) conducted a web-based survey to quantify the role and scope of practice of physiotherapists involved in haemophilia care. The survey was sent to more than 200 physiotherapists registered on the EAHAD database. Questions concerned their work practices including assessment and treatment activities and level of autonomy. RESULTS: Eighty physiotherapists from twenty-four European countries responded. Considerable heterogeneity exists in roles, responsibilities, and clinical practice of physiotherapists, particularly in access to and type of physiotherapy treatment provided, as well as the skill set and autonomy of physiotherapists to make independent assessment and treatment decisions. DISCUSSION: This pan-European survey establishes a context to support physiotherapy role development and professional identity. Key recommendations include the following: (a) establishing a pan-European network to support collaboration and education for physiotherapists working in haemophilia, (b) developing a core skills and capability framework to ensure person-centred approaches are central as well as working in partnership with those with the condition to maximize early recovery, support self-management and enablement in remaining active and independent, (c) regular training, standardized validation and maintenance of competency for assessment tools, (d) well-designed randomized clinical studies with larger numbers of participants from multiple sites should be the focus of future research.

The phloem sucrose transporter, AtSUC2, is promiscuous with respect to substrate recognition, transporting a range of glucosides in addition to sucrose, including naturally occurring coumarin glucosides. We used the inherent fluorescence of coumarin glucosides to probe the specificity of AtSUC2 for its substrates, and determined the structure-activity relationships that confer phloem transport in vivo using Arabidopsis seedlings. In addition to natural coumarin glucosides, we synthesized new compounds to identify key structural features that specify recognition by AtSUC2. Our analysis of the structure-activity relationship revealed that the presence of a free hydroxyl group on the coumarin moiety is essential for binding by AtSUC2 and subsequent phloem mobility. Structural modeling of the AtSUC2 substrate-binding pocket explains some important structural requirements for the interaction of coumarin glucosides with the AtSUC2 transporter.

INTRODUCTION: Comprehensive musculoskeletal assessment for monitoring joint health in haemophilia includes both physical assessment with Haemophilia Joint Health Score (HJHS) and assessment of self-reported function by Haemophilia Activities List (HAL). METHODS: Correlation between physical assessment and joint function was undertaken between HJHS and HAL in patients with SHA and SHB who had both assessments at the same visit over a one-year period. RESULTS: Data from 120 patients (96-SHA/24 = SHB) with a median age 33 years (range 19-73) were included. Median total HJHS was 19, increasing with age: 18-30 years-7, 31-50 years-25 and 51-73 years-44. Similarly, median total HAL score was 80 with decreased function associated with increasing age: 18-30 years-90.4, 31-59 years-71.7, 51-73 years-49.5. Median Total HJHS and HAL demonstrated strong correlation (rs = 0.66, P < 0.01). Moderate-to-strong correlations were seen across the entire age group between the HJHS LL and UL subtotals and corresponding limb HAL domains. Within age groups, correlations were less significant particularly for the upper UL domains in HAL and the UL HJHS score. The wide range of ROM in joints categorized as markedly affected (ie, ROM loss score = 3) highlights the potential ceiling effect of this domain score and its use in chronically damaged joints. CONCLUSION: HJHS and HAL showed moderate-to-strong correlation with discrepancy in some individual patients. Prospective studies are required to better understand the clinical utility of both especially in severe joint disease where HAL may have a potential advantage.

The first Team Haemophilia Education (THE) Meeting was held on 7-8 May 2015 in Amsterdam, The Netherlands. It aimed to promote the optimal care of patients with haemophilia through education of the multidisciplinary treatment team. This was achieved by reviewing the latest developments in haemophilia management, considering how these can be implemented in the clinic to improve patient care and providing a platform for networking and debate for all haemophilia treatment team members. The second THE Meeting was held on 19-20 May in Frankfurt, Germany, and participants included doctors, nurses, physiotherapists, patient representatives and data management staff from 20 different countries. Topics covered the role of the multidisciplinary team in delivering the best haemophilia care, challenges in the management of haemophilia across Europe, available clotting factor treatments, future treatments and the use of genetics in advising carriers of haemophilia. This report is a summary of the key developments in haemophilia care presented by various investigators and healthcare professionals at THE Meeting 2016.

Scientific literature increasingly calls for studies to translate evidence-based interventions into real-world contexts balancing fidelity to the original design and fit to the new setting. The Risk Avoidance Partnership (RAP) is a health promotion intervention originally designed to train active drug users to become Peer Health Advocates. A theoretically driven approach was used to adapt RAP to fit implementation in outpatient methadone treatment clinics and pilot it with clinic patients. Ethnographic observations and process tracking documented the RAP translation and pilot experience, and clinic and community characteristics relevant to program implementation. Clinic administrators, staff, and patients were interviewed on their values, capacities, interest in RAP, perceived challenges of implementing RAP in drug treatment clinics, and experiences during the pilot. Findings indicated that RAP core components can be met when implemented in these settings and RAP can fit with the goals, interests, and other programs of the clinic. Balancing fidelity and fit requires recognition of the mutual impacts RAP and the clinic have on each other, which generate new interactions among staff and require ongoing specification of RAP to keep abreast of clinic and community changes. Collaboration of multiple stakeholders significantly benefited translation and pilot processes.

Nearly 150 different enzymatically modified forms of the four canonical residues in RNA have been identified. For instance, enzymes of the ADAR (adenosine deaminase acting on RNA) family convert adenosine residues into inosine in cellular dsRNAs. Recent findings show that DNA endonuclease V enzymes have undergone an evolutionary transition from cleaving 3' to deoxyinosine in DNA and ssDNA to cleaving 3' to inosine in dsRNA and ssRNA in humans. Recent work on dsRNA-binding domains of ADARs and other proteins also shows that a degree of sequence specificity is achieved by direct readout in the minor groove. However, the level of sequence specificity observed is much less than that of DNA major groove-binding helix-turn-helix proteins. We suggest that the evolution of DNA-binding proteins following the RNA to DNA genome transition represents the major advantage that DNA genomes have over RNA genomes. We propose that a hypothetical RNA modification, a RRAR (ribose reductase acting on genomic dsRNA) produced the first stretches of DNA in RNA genomes. We discuss why this is the most satisfactory explanation for the origin of DNA. The evolution of this RNA modification and later steps to DNA genomes are likely to have been driven by cellular genome co-evolution with viruses and intragenomic parasites. RNA modifications continue to be involved in host-virus conflicts; in vertebrates, edited cellular dsRNAs with inosine-uracil base pairs appear to be recognized as self RNA and to suppress activation of innate immune sensors that detect viral dsRNA.

Wide field-of-view gigapixel imaging systems capable of diffraction-limited resolution and video-rate acquisition have a broad range of applications, including sports event broadcasting, security surveillance, astronomical observation, and bioimaging. The complexity of the system integration of such devices demands precision optical components that are fully characterized and qualified before being integrated into the final system. In this work, we present component and assembly level characterizations of microcameras in our first gigapixel camera, the AWARE-2. Based on the results of these measurements, we revised the optical design and assembly procedures to construct the second generation system, the AWARE-2 Retrofit, which shows significant improvement in image quality.

BACKGROUND: Postoperative cognitive dysfunction (POCD) is well established in adults but has been underinvestigated in children. As day-case procedures are increasingly common, it is important to establish whether children suffer significant POCD. Pediatric POCD has been associated with several intravenous and inhalation anesthetics, but isoflurane has not been studied. As evidence indicates superior recovery after propofol, the study compared POCD after propofol or isoflurane anesthesia. OBJECTIVES: To compare the effects of propofol versus isoflurane upon children's POCD. METHODS: Fifty-eight children aged 5-14 years were randomized to propofol (total intravenous anesthesia) or isoflurane for day-case dental procedures. Reaction time (RT), verbal and visual memory, psychomotor coordination, and attention were assessed preoperatively, prior to discharge and at 24 h. RESULTS: Reaction time and psychomotor control were impaired postoperatively in both groups but recovered at 24 h. Delayed verbal recall was significantly impaired only after propofol. Both groups had significant impairment of visual memory postoperatively and at 24 h, and of recognition memory postoperatively only. CONCLUSIONS: Propofol and isoflurane exert similar adverse effects on RT, psychomotor coordination, and visual memory. Selective impairment of verbal recall by propofol is consistent with adult evidence of the drug's effect on retrieval. The enduring postoperative impairment of memory has implications for instructions to parents and caregivers for the safety and well-being of children in the 24 h after day-case anesthesia with propofol and isoflurane.

This study examines the barriers and facilitators of retention among patients receiving buprenorphine/naloxone at eight community-based opioid treatment programs across the United States. Participants (n = 105) were recruited up to three and a half years after having participated in a randomized clinical trial comparing the effect of buprenorphine/naloxone and methadone on liver function. Semi-structured interviews were conducted with 67 patients provided with buprenorphine/naloxone who had terminated early and 38 patients who had completed at least 24 weeks of the trial. Qualitative data were analyzed using the constant comparison method. Barriers to buprenorphine/naloxone retention that emerged included factors associated with: (1) the design of the clinical trial; (2) negative medication or treatment experience; and (3) personal circumstances. The facilitators comprised: (1) positive experience with the medication; (2) personal determination and commitment to complete; and (3) staff encouragement and support. The themes drawn from interviews highlight the importance of considering patients' prior experience with buprenorphine/naloxone and methadone, medication preference, personal circumstances, and motivation to abstain from illicit use or misuse of opioids, as these may influence retention. Ongoing education of patients and staff regarding buprenorphine/naloxone, especially in comparison to methadone, and support from staff and peers are essential.

INTRODUCTION: Hemophilia is an inherited bleeding disorder. Bleeding, and in particular joint hemorrhage results in chronic arthropathy and disability. Acute and chronic pain are frequent and limit activity and participation and result in decreased health-related quality of life. Remarkable progress has been made in the diagnosis and treatment of hemophilia but bleeding continues to prove recalcitrant to currently available treatments and joint disease remains problematic. Physiotherapy and pain management are mainstays of current multidisciplinary integrated care of people with hemophilia (PWH). The focus of this review is on preservation of joint health in the era of new and innovative therapies. AREAS COVERED: A search of the PubMed Central was conducted on 1 February 2024 using the MeSH Major Topic terms identified as keywords for the manuscript. This review will highlight what is known and unknown about joint bleeding and arthropathy, including insights on pain as a related complication. EXPERT OPINION: Recent advances in therapeutic interventions aimed at promoting healthy joints in PWH will be discussed, including both the pharmacological treatment landscape and related strategies to promote joint health.
