European principles of care for physiotherapy provision for persons with inherited bleeding disorders: Perspectives of physiotherapists and patients.

INTRODUCTION: In their Chronic Care Model, the World Health Organisation states that people with chronic disorders and their families should be informed about the expected course, potential complications, and effective strategies to prevent complications and manage symptoms. Physiotherapists are a key professional group involved in the triage, assessment and management of musculoskeletal conditions of persons with a bleeding disorder (PWBD). Nevertheless, recent reports describe access to physiotherapy for those with these conditions is only sometimes available. AIM: Access to high quality individualised physiotherapy should be ensured for all PWBD, including those with mild and moderate severities, male and female, people with von Willebrand Disease (vWD) and other rare bleeding disorders. Physiotherapy should be viewed as a basic requisite in their multidisciplinary care. METHODS/ RESULTS: Following a series of meetings with physiotherapists representing the European Association for Haemophilia and Allied Disorders (EAHAD) and PWBD representing the European Haemophilia Consortium (EHC) and a review of publications in the field, eight core principles of physiotherapy care for persons with a bleeding disorder have been co-produced by EAHAD and EHC. CONCLUSION: These eight principles outline optimum standards of practice in order to advocate personalised patient-centred care for physical health in which both prevention and interventions include shared decision making, and supported self-management.

Hydroclimate footprint of pan-Asian monsoon water isotope during the last deglaciation.

Oxygen isotope speleothem records exhibit coherent variability over the pan-Asian summer monsoon (AM) region. The hydroclimatic representation of these oxygen isotope records for the AM, however, has remained poorly understood. Here, combining an isotope-enabled Earth system model in transient experiments with proxy records, we show that the widespread AM δ18Oc signal during the last deglaciation (20 to 11 thousand years ago) is accompanied by a continental-scale, coherent hydroclimate footprint, with spatially opposite signs in rainfall. This footprint is generated as a dynamically coherent response of the AM system primarily to meltwater forcing and secondarily to insolation forcing and is further reinforced by atmospheric teleconnection. Hence, widespread δ18Op depletion in the AM region is accompanied by a northward migration of the westerly jet and enhanced southwesterly monsoon wind, as well as increased rainfall from South Asia (India) to northern China but decreased rainfall in southeast China.

Evolution of Haemophilia Care in Europe: 10 years of the principles of care.

INTRODUCTION: The European principles of care in haemophilia marked their first decade in 2018. These guiding principles were the beginning of the European Haemophilia Consortium (EHC) review of countries' adherence to these principles in 2009, 2012, 2015 and 2018. The aim of this paper was to examine the implementation of the principles and how they have impacted the evolution of care in the last decade, as well as to identify remaining gaps and proposes future directions. METHODS: In 2018, the EHC distributed a survey to EHC national member organisations in English and Russian and encouraged them to discuss responses with local clinicians for accuracy. Data was also cross-referenced and validated for countries in earlier surveys using additional available resources. RESULTS: The 10-year-old European principles had a significant impact on the development of care for haemophilia and related bleeding disorders in Europe. They set objectives around which multi-stakeholder groups have established recommendations and specific steps for the progressive improvement of care for bleeding disorders. However, some have been promoted and implemented more than others. CONCLUSION: Monitoring adherence to, and impact of, the European Principles of Care significantly assists in tracking developments and highlighting gaps. Countries' inability to report consistent and coherent data remains a challenge and hinders both provision of treatment and care for patients as well as optimal national and European healthcare systems.

The Patient Reported Outcomes, Burdens and Experiences (PROBE) Project: development and evaluation of a questionnaire assessing patient reported outcomes in people with haemophilia.

BACKGROUND: The interest of health care agencies, private payers and policy makers for patient-reported outcomes (PRO) is continuously increasing. There is a substantial need to improve capacity to collect and interpret relevant PRO data to support implementation of patient-centered research and optimal care in haemophilia. The Patient Reported Outcomes, Burdens and Experiences (PROBE) Project aims to develop a patient-led research network, to develop a standardized questionnaire to gather patient-reported outcomes and to perform a feasibility study of implementing the PROBE questionnaire. METHODS: A pilot questionnaire was developed using focus group methodology. Content and face validity were assessed by a pool of persons living with haemophilia (PWH) and content experts through interactive workshops. The PROBE questionnaire was translated with the forward-backward approach. PROBE recruited national haemophilia patient non-governmental organizations (NGOs) to administer the questionnaire to people with and without haemophilia. PROBE measured the time to complete the questionnaire and gathered feedback on its content and clarity; staff time and cost required to implement the questionnaire were also collected. RESULTS: The PROBE questionnaire is comprised of four major sections (demographic data, general health problems, haemophilia-related health problems and health-related quality of life using EQ-5D-5L and EQ-VAS). Seventeen NGOs participated in the pilot study of the PROBE Project, recruiting 656 participants. Of these, 71% completed the questionnaire within 15 min, and all participants completed within 30 min. The median total staff and volunteer time required for the NGOs to carry out the study within their country was 9 h (range 2 to 40 h). NGO costs ranged from $22.00 to $543.00 USD per country, with printing and postage being the most commonly reported expenditures. CONCLUSIONS: The PROBE questionnaire assesses patient-important reported outcomes in PWH and control participants, with a demonstrated short completion time. PROBE proved the feasibility to engage diverse patient communities in the structured generation of real-world outcome research at all stages. TRIAL REGISTRATION: Trial registration: NCT02439710.

Progression of hepatitis C in the haemophiliac population in Ireland, after 30 years of infection in the pre-DAA treatment era.

INTRODUCTION: Prior to the introduction of viral inactivation of factor concentrates and screening of blood, 225 people with haemophilia became infected with hepatitis C (HCV) in Ireland. AIM: Our aim was to assess liver disease progression and mortality in this population after 30 years of infection. METHODS: Demographic and clinical data were collected from medical records in five hepatology units and one infectious disease unit retrospectively in 2005, and on four subsequent occasions. RESULTS: The participation rate was 73% (165/225). Eighty three percent of patients, who had been tested for RNA (n = 106/128), developed chronic HCV infection. Thirty four percent were co-infected with HIV. All-cause mortality, after approximately 30 years of infection with chronic HCV, was 44% in HIV positive patients and 29% in HIV negative patients. Liver-related mortality was 12.5% and did not vary significantly by HIV status. Thirty seven percent of patients had developed advanced liver disease, including 20% with cirrhosis and 9% with hepatocellular carcinoma. In the pre-interferon-free direct acting antivirals era, 57% (n = 60/106) of patients were treated for HCV, 65% of whom achieved a sustained virological response. Successfully treated patients had few adverse liver outcomes. CONCLUSION: After 30 years of infection, 40% of the patients who had evidence of chronic HCV had developed advanced liver disease, such as cirrhosis and HCC, or had died from liver-related causes. This proportion is high relative to similar international cohorts despite good anti-HCV treatment uptake and responses.

Survey of coagulation factor concentrates tender and procurement procedures in 38 European Countries.

INTRODUCTION: Procurement of coagulation factor concentrates (CFCs) for the treatment of haemophilia is a vital process that determines the quantity and quality of factor replacement therapy. AIM: The aim of this study was to examine the different tender and procurement systems used in Europe for the procurement of CFCs and the outcomes produced by the various systems. METHODS: The survey questionnaire consisted of 30 items and explored various aspects of the procurement process including the prices of CFCs. In 2014, the survey was sent out by the European Haemophilia Consortium (EHC) to 45 national haemophilia patient organizations affiliated to the EHC in all European countries as well as to a designated clinician familiar with the procurement process. RESULTS: The survey was completed by 38 European countries. Nineteen countries use a tender process, 17 an alternative procurement process and 2 use a combination of methods. A wide variety of agencies and individuals are involved in the process. Factors associated with optimum outcome and lower prices include a tender process with a specific legal framework and a tender board including haemophilia clinicians and patient organization representatives. Safety was reported as the most important selection criterion but given the safety profile of almost all currently licensed products, price was the main criterion used in many countries. CONCLUSION: The involvement of both clinicians and patient organizations greatly improves the outcome of a tender or procurement process, as does the presence of a legal framework that governs the process.

Arctic cyclone water vapor isotopes support past sea ice retreat recorded in Greenland ice.

Rapid Arctic warming is associated with important water cycle changes: sea ice loss, increasing atmospheric humidity, permafrost thaw, and water-induced ecosystem changes. Understanding these complex modern processes is critical to interpreting past hydrologic changes preserved in paleoclimate records and predicting future Arctic changes. Cyclones are a prevalent Arctic feature and water vapor isotope ratios during these events provide insights into modern hydrologic processes that help explain past changes to the Arctic water cycle. Here we present continuous measurements of water vapor isotope ratios (δ(18)O, δ(2)H, d-excess) in Arctic Alaska from a 2013 cyclone. This cyclone resulted in a sharp d-excess decrease and disproportional δ(18)O enrichment, indicative of a higher humidity open Arctic Ocean water vapor source. Past transitions to warmer climates inferred from Greenland ice core records also reveal sharp decreases in d-excess, hypothesized to represent reduced sea ice extent and an increase in oceanic moisture source to Greenland Ice Sheet precipitation. Thus, measurements of water vapor isotope ratios during an Arctic cyclone provide a critical processed-based explanation, and the first direct confirmation, of relationships previously assumed to govern water isotope ratios during sea ice retreat and increased input of northern ocean moisture into the Arctic water cycle.

A preliminary investigation of schematic beliefs and unusual experiences in children.

BACKGROUND: In cognitive models of adult psychosis, schematic beliefs about the self and others are important vulnerability and maintaining factors, and are therefore targets for psychological interventions. Schematic beliefs have not previously been investigated in children with distressing unusual, or psychotic-like, experiences (UEDs). The aim of this study was firstly to investigate whether a measure of schematic beliefs, originally designed for adults with psychosis, was suitable for children; and secondly, to examine the association of childhood schematic beliefs with internalising and externalising problems and with UEDs. METHOD: Sixty-seven children aged 8-14 years, with emotional and behavioural difficulties, completed measures of UEDs, internalising (depression and anxiety), and externalising (conduct and hyperactivity-inattention) problems, together with the Brief Core Schema Scales (BCSS). RESULTS: The BCSS was readily completed by participants, and scale psychometric properties were good. Children tended to view themselves and others positively. Internalising and externalising problems and UEDs were all associated with negative schematic beliefs; effect sizes were small to medium. CONCLUSIONS: Schematic beliefs in young people can be measured using the BCSS, and negative schematic beliefs are associated with childhood psychopathology and with UEDs. Schematic beliefs may therefore form a useful target in psychological interventions for young people with UEDs.

Haemophilia care in Europe - a survey of 35 countries.

A questionnaire was circulated in 2012 to national haemophilia patient organizations in Europe affiliated to the European Haemophilia Consortium (EHC) and the World Federation of Hemophilia (WFH) to seek information about the organization of haemophilia care and treatment available at a national level. The 35 responses received highlighted major differences in the availability of treatment and care. There was a wide range in factor VIII consumption with usage ranging from 0.20 IU per capita in Armenia to 8.56 IU per capita in Sweden (median: IU per capita). The decrease in health budgets in many countries was not matched by decreases in use of FVIII per capita. In the 19 countries that responded to the previous survey, there was a significant improvement in access to prophylaxis and home treatment.

Treatment for life for severe haemophilia A- A cost-utility model for prophylaxis vs. on-demand treatment.

Prophylaxis has been established as the treatment of choice in children with haemophilia and its continuation into the adult years has been shown to decrease morbidity throughout life. The cost of factor therapy has made the option questionable in cost-effectiveness studies. The role of prophylaxis in pharmacokinetic dosage and tolerization against inhibitor formation were used to model the cost utility of prophylaxis vs. on-demand (OD) therapy over a lifetime horizon in severe haemophilia A. The model was applied to a single provider national health system exemplified by the United Kingdom's National Health Service and a third party provider in the United States. The incremental cost-effectiveness ratio (ICER) was estimated and compared to threshold values used by payer agencies to guide reimbursement decisions. A cost per quality-adjusted life year (QALY) was also estimated for Sweden. Prophylaxis was dominant over OD treatment in the UK. The model resulted in an ICER - $68 000 - within the range of treatments reimbursed in the USA. In Sweden, a cost/QALY of SEK 1.1 million was also within the range of reimbursed treatments in that country. Dosage- and treatment-induced inhibitor incidence were the most important variables in the model. Subject to continuing clinical evidence of the effectiveness of pharmacokinetic dosage and the role of prophylaxis in decreasing inhibitor incidence, treatment for life with prophylaxis is a cost-effective therapy, using current criteria for the reimbursement of health care technologies in a number of countries.

A survey of the outcome of prophylaxis, on-demand treatment or combined treatment in 18-35-year old men with severe haemophilia in six countries.

A number of studies have been published on the benefits of prophylactic treatment in adults with haemophilia. However, in many countries, it is considered as optional due to financial constraints. This survey was carried out to examine the long-term effects of prophylaxis and the continuing benefit of the treatment into adulthood. Self-assessed health-related data and the EQ-5D questionnaire measuring health utility were collected from 124 men (26.9 ± 4.6 years) from Canada (N = 40), France (N = 14), Ireland (N = 17), the Netherlands (N = 16), Poland (N = 24) and the UK (N = 13). The respondents were split into four groups: On-Demand, <50% life on prophylaxis, ≥ 50% life on prophylaxis, Prophylaxis. Overall, long-term prophylaxis results in lower presence of target joints (P ≤ 0.001), occurrence of serious bleeding episodes (P ≤ 0.05), recurring bleeding episodes (P ≤ 0.01) and requirement for surgical procedures (P ≤ 0.05). Furthermore, health utility (P ≤ 0.01) in the On-demand group was significantly lower (P ≤ 0.01) compared to the ≥ 50% life on prophylaxis and the Prophylaxis group. No significant differences between countries were found except between the Netherlands and Poland, with Poland showing the lowest health utility (P ≤ 0.01) and the most problems with mobility (P ≤ 0.05) and pain/discomfort (P ≤ 0.001). The Netherlands showed the highest health utility (0.915) followed by Canada (0.791), Ireland (0.786), UK (0.768), France (0.687) and Poland (0.629). The results demonstrate consistently higher quality of life of individuals who are on long-term prophylactic treatment when compared to on-demand treatment or intermittent prophylaxis and on -demand treatment.

Antibody mediated rejection associated with complement factor h-related protein 3/1 deficiency successfully treated with eculizumab.

Antibody mediated rejection (AMR) activates the classical complement pathway and can be detrimental to graft survival. AMR can be accompanied by thrombotic microangiopathy (TMA). Eculizumab, a monoclonal C5 antibody prevents induction of the terminal complement cascade (TCC) and has recently emerged as a therapeutic option for AMR. We present a highly sensitized 13-year-old female with end-stage kidney disease secondary to spina bifida-associated reflux nephropathy, who developed severe steroid-, ATG- and plasmapheresis-resistant AMR with TMA 1 week post second kidney transplant despite previous desensitization therapy with immunoglobulin infusions. Eculizumab rescue therapy resulted in a dramatic improvement in biochemical (C3; creatinine) and hematological (platelets) parameters within 6 days. The patient was proven to be deficient in complement Factor H-related protein 3/1 (CFHR3/1), a plasma protein that regulates the complement cascade at the level of C5 conversion and has been involved in the pathogenesis of atypical hemolytic uremic syndrome caused by CFH autoantibodies (DEAP-HUS). CFHR1 deficiency may have worsened the severe clinical progression of AMR and possibly contributed to the development of donor-specific antibodies. Thus, screening for CFHR3/1 deficiency should be considered in patients with severe AMR associated with TMA.

Serum magnesium in the first week of life in extremely low birth weight infants.

BACKGROUND: Evidence that antenatal administration of magnesium sulfate (MgSO(4)) to women in preterm labor may confer fetal neuroprotection is growing. MgSO(4) crosses the placenta and can affect the neonate. Magnesium homeostasis in extremely low birth weight (ELBW) infants remains to be clarified. OBJECTIVES: We aimed to assess the natural progression of serum magnesium (Mg) in ELBW infants not exposed to antenatal MgSO(4) during the first month of life. METHODS: Laboratory data of a group of ELBW infants born in a tertiary center over a 1-year period were analyzed. Serum Mg was recorded daily for the first week and thereafter each week for a month for each infant. Concurrent calcium, phosphate and alkaline phosphatase were measured. RESULTS: 51 preterm infants (24 female) with a birth weight <1,000 g were included (33 were born at <27 weeks' gestation). The mean magnesium ranged from 0.9 to 1.1 mmol/l over the first week with a minimum of 0.62 mmol/l and maximum of 1.53 mmol/l. Mg rises in the first few days before stabilizing and remains within a narrow range thereafter. CONCLUSIONS: In ELBW infants, Mg tends to rise initially then stabilize and remain normal thereafter. The effect of antenatal MgSO(4) on magnesium homeostasis requires further study.

The National Neonatal Transport Programme (NNTP) 2004-2009.

A retrospective analysis of all National Neonatal Transport Programme (NNTP) transport data from 2004-2009 was performed. 1621 transports were conducted during this period with a yearly average of 271. The majority (96%) were ground transports. 1118 (69%) were forward transfers. Of the 446 (27.5%) retrotransfers, 411 (91%.) were to tertiary centres. When transported, 592 infants (36.5%) were <48 hours old and 770 (47.5%) were <1 week old. 902 transports (55%) involved infants <32 wks birth-gestation and 720 (44%) involved infants weighing <1500gms. Transport for management of patent ductus arteriosus accounted for 357 (22%). The average mobilisation time was 34 minutes. 54% of transports were completed after scheduled service hours. The NNTP currently transports similar numbers of critically ill infants during its 8hr service compared with neonatal transport services that operate 24hr services. Performing PDA ligations in a tertiary neonatal unit would significantly reduce the number of neonatal transports required annually.

A consultant paediatrician led and public health nurse (PHN) provided Community Enuresis Clinic as a model of care.

A dedicated Community Enuresis Clinic was established in 2004 in Cavan and Monaghan. The service was audited using ERIC (Education and Resources for Improving Childhood Continence) guidelines. There were 106 males and 47 females, giving an M: F ratio of 2.3:1. Monosymptomatic Nocturnal Enuresis (MNE) accounted for 127 (83%). Adequate follow-up was available for 108 children with MNE and in this group Initial Success was 49% (ERIC target 50%). 71% were dry at 1 year. There was a dropout rate of 20% in the MNE group (ERIC minimum standard < 25%). We believe the structure of this community based clinic and its approach to MNE management has been successful.

Hydrogen isotope correction for laser instrument measurement bias at low water vapor concentration using conventional isotope analyses: application to measurements from Mauna Loa Observatory, Hawaii.

The hydrogen and oxygen isotope ratios of water vapor can be measured with commercially available laser spectroscopy analyzers in real time. Operation of the laser systems in relatively dry air is difficult because measurements are non-linear as a function of humidity at low water concentrations. Here we use field-based sampling coupled with traditional mass spectrometry techniques for assessing linearity and calibrating laser spectroscopy systems at low water vapor concentrations. Air samples are collected in an evacuated 2 L glass flask and the water is separated from the non-condensable gases cryogenically. Approximately 2 µL of water are reduced to H(2) gas and measured on an isotope ratio mass spectrometer. In a field experiment at the Mauna Loa Observatory (MLO), we ran Picarro and Los Gatos Research (LGR) laser analyzers for a period of 25 days in addition to periodic sample collection in evacuated flasks. When the two laser systems are corrected to the flask data, they are strongly coincident over the entire 25 days. The δ(2)H values were found to change by over 200‰ over 2.5 min as the boundary layer elevation changed relative to MLO. The δ(2)H values ranged from -106 to -332‰, and the δ(18)O values (uncorrected) ranged from -12 to -50‰. Raw data from laser analyzers in environments with low water vapor concentrations can be normalized to the international V-SMOW scale by calibration to the flask data measured conventionally. Bias correction is especially critical for the accurate determination of deuterium excess in dry air.

Haemophilia care in Europe: a survey of 19 countries.

In 2009, a questionnaire was circulated to 19 national haemophilia patient organizations in Europe affiliated to the European Haemophilia Consortium (EHC) and the World Federation of Hemophilia (WFH) to seek information about the organization of haemophilia care and treatment available at a national level. The responses received highlighted differences in the level of care despite the recent promulgation of consensus guidelines designed to standardize the care of haemophilia throughout the continent of Europe. There was a wide range in factor VIII consumption with usage ranging from 0.38 IU per capita in Romania to 8.7 IU per capita in Sweden (median: 3.6 IU per capita). Despite the specific inclusion of coagulation factor concentrate in the WHO list of essential medications, cryoprecipitate is still used in some eastern European countries.

YkdA and YvtA, HtrA-like serine proteases in Bacillus subtilis, engage in negative autoregulation and reciprocal cross-regulation of ykdA and yvtA gene expression.

HtrA-type serine proteases participate in folding and degradation of aberrant proteins and in processing and maturation of native proteins. Mutation of the corresponding genes often confers a pleiotropic phenotype that can include temperature sensitivity, sensitivity to osmotic and oxidative stress, and attenuated virulence. There are three HtrA-type serine proteases, YkdA, YvtA, and YycK, encoded in the Bacillus subtilis genome. In this report we show that YkdA and YvtA display many similarities: their expression profiles during the growth cycle in wild-type and mutant backgrounds are very alike, with expression being directed by very similar promoters. Both are induced by temperature upshift and by heterologous amylases at the transition phase of the growth cycle. These characteristics are quite different for YycK, suggesting that it has a cellular function distinct from that of the other two proteases or that it performs the same function but under different conditions. We also show that inactivation of either ykdA or yvtA results in compensating overexpression of the other gene, especially during stress conditions, with a concomitant increase in resistance to heat and hydrogen peroxide stresses. Mutation of both ykdA and yvtA leads to growth defects and to thermosensitivity. The fact that their expression increases dramatically at the transition phase of the growth cycle under certain conditions suggests that the YkdA and YvtA proteases may function in the processing, maturation, or secretion of extracellular enzymes in B. subtilis.
