The largest kindred with inherited prion disease P102L, historically Gerstmann-Sträussler-Scheinker syndrome, originates from central England, with émigrés now resident in various parts of the English-speaking world. We have collected data from 84 patients in the large UK kindred and numerous small unrelated pedigrees to investigate phenotypic heterogeneity and modifying factors. This collection represents by far the largest series of P102L patients so far reported. Microsatellite and genealogical analyses of eight separate European kindreds support multiple distinct mutational events at a cytosine-phosphate diester-guanidine dinucleotide mutation hot spot. All of the smaller P102L kindreds were linked to polymorphic human prion protein gene codon 129M and were not connected by genealogy or microsatellite haplotype background to the large kindred or each other. While many present with classical Gerstmann-Sträussler-Scheinker syndrome, a slowly progressive cerebellar ataxia with later onset cognitive impairment, there is remarkable heterogeneity. A subset of patients present with prominent cognitive and psychiatric features and some have met diagnostic criteria for sporadic Creutzfeldt-Jakob disease. We show that polymorphic human prion protein gene codon 129 modifies age at onset: the earliest eight clinical onsets were all MM homozygotes and overall age at onset was 7 years earlier for MM compared with MV heterozygotes (P = 0.02). Unexpectedly, apolipoprotein E4 carriers have a delayed age of onset by 10 years (P = 0.02). We found a preponderance of female patients compared with males (54 females versus 30 males, P = 0.01), which probably relates to ascertainment bias. However, these modifiers had no impact on a semi-quantitative pathological phenotype in 10 autopsied patients. These data allow an appreciation of the range of clinical phenotype, modern imaging and molecular investigation and should inform genetic counselling of at-risk individuals, with the identification of two genetic modifiers.

The SARS-CoV-2 Omicron BA.1 variant emerged in 20211 and has multiple mutations in its spike protein2. Here we show that the spike protein of Omicron has a higher affinity for ACE2 compared with Delta, and a marked change in its antigenicity increases Omicron’s evasion of therapeutic monoclonal and vaccine-elicited polyclonal neutralizing antibodies after two doses. mRNA vaccination as a third vaccine dose rescues and broadens neutralization. Importantly, the antiviral drugs remdesivir and molnupiravir retain efficacy against Omicron BA.1. Replication was similar for Omicron and Delta virus isolates in human nasal epithelial cultures. However, in lung cells and gut cells, Omicron demonstrated lower replication. Omicron spike protein was less efficiently cleaved compared with Delta. The differences in replication were mapped to the entry efficiency of the virus on the basis of spike-pseudotyped virus assays. The defect in entry of Omicron pseudotyped virus to specific cell types effectively correlated with higher cellular RNA expression of TMPRSS2, and deletion of TMPRSS2 affected Delta entry to a greater extent than Omicron. Furthermore, drug inhibitors targeting specific entry pathways3 demonstrated that the Omicron spike inefficiently uses the cellular protease TMPRSS2, which promotes cell entry through plasma membrane fusion, with greater dependency on cell entry through the endocytic pathway. Consistent with suboptimal S1/S2 cleavage and inability to use TMPRSS2, syncytium formation by the Omicron spike was substantially impaired compared with the Delta spike. The less efficient spike cleavage of Omicron at S1/S2 is associated with a shift in cellular tropism away from TMPRSS2-expressing cells, with implications for altered pathogenesis.

Although two-dose mRNA vaccination provides excellent protection against SARS-CoV-2, there is little information about vaccine efficacy against variants of concern (VOC) in individuals above eighty years of age1. Here we analysed immune responses following vaccination with the BNT162b2 mRNA vaccine2 in elderly participants and younger healthcare workers. Serum neutralization and levels of binding IgG or IgA after the first vaccine dose were lower in older individuals, with a marked drop in participants over eighty years old. Sera from participants above eighty showed lower neutralization potency against the B.1.1.7 (Alpha), B.1.351 (Beta) and P.1. (Gamma) VOC than against the wild-type virus and were more likely to lack any neutralization against VOC following the first dose. However, following the second dose, neutralization against VOC was detectable regardless of age. The frequency of SARS-CoV-2 spike-specific memory B cells was higher in elderly responders (whose serum showed neutralization activity) than in non-responders after the first dose. Elderly participants showed a clear reduction in somatic hypermutation of class-switched cells. The production of interferon-γ and interleukin-2 by SARS-CoV-2 spike-specific T cells was lower in older participants, and both cytokines were secreted primarily by CD4 T cells. We conclude that the elderly are a high-risk population and that specific measures to boost vaccine responses in this population are warranted, particularly where variants of concern are circulating., Nature, 596 (7872), ISSN:0028-0836, ISSN:1476-4687

The spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is critical for virus infection through the engagement of the human ACE2 protein1 and is a major antibody target. Here we show that chronic infection with SARS-CoV-2 leads to viral evolution and reduced sensitivity to neutralizing antibodies in an immunosuppressed individual treated with convalescent plasma, by generating whole-genome ultra-deep sequences for 23 time points that span 101 days and using in vitro techniques to characterize the mutations revealed by sequencing. There was little change in the overall structure of the viral population after two courses of remdesivir during the first 57 days. However, after convalescent plasma therapy, we observed large, dynamic shifts in the viral population, with the emergence of a dominant viral strain that contained a substitution (D796H) in the S2 subunit and a deletion (ΔH69/ΔV70) in the S1 N-terminal domain of the spike protein. As passively transferred serum antibodies diminished, viruses with the escape genotype were reduced in frequency, before returning during a final, unsuccessful course of convalescent plasma treatment. In vitro, the spike double mutant bearing both ΔH69/ΔV70 and D796H conferred modestly decreased sensitivity to convalescent plasma, while maintaining infectivity levels that were similar to the wild-type virus.The spike substitution mutant D796H appeared to be the main contributor to the decreased susceptibility to neutralizing antibodies, but this mutation resulted in an infectivity defect. The spike deletion mutant ΔH69/ΔV70 had a twofold higher level of infectivity than wild-type SARS-CoV-2, possibly compensating for the reduced infectivity of the D796H mutation. These data reveal strong selection on SARS-CoV-2 during convalescent plasma therapy, which is associated with the emergence of viral variants that show evidence of reduced susceptibility to neutralizing antibodies in immunosuppressed individuals.

The kinetics of the immune changes in COVID-19 across severity groups have not been rigorously assessed. Using immunophenotyping, RNA sequencing, and serum cytokine analysis, we analyzed serial samples from 207 SARS-CoV2-infected individuals with a range of disease severities over 12 weeks from symptom onset. An early robust bystander CD8+ T cell immune response, without systemic inflammation, characterized asymptomatic or mild disease. Hospitalized individuals had delayed bystander responses and systemic inflammation that was already evident near symptom onset, indicating that immunopathology may be inevitable in some individuals. Viral load did not correlate with this early pathological response but did correlate with subsequent disease severity. Immune recovery is complex, with profound persistent cellular abnormalities in severe disease correlating with altered inflammatory responses, with signatures associated with increased oxidative phosphorylation replacing those driven by cytokines tumor necrosis factor (TNF) and interleukin (IL)-6. These late immunometabolic and immune defects may have clinical implications., Graphical abstract, The immune changes that underlie COVID-19 severity have not been fully defined. By analyzing a longitudinal cohort of COVID-19 patients and integrating inflammatory factors, immunophenotyping, and transcriptome data, Bergamaschi et al. identify both early and persistent immune changes that distinguish mild and/or asymptomatic from more severe disease.

BackgroundPulmonary arterial hypertension (PAH) covers a range of life-limiting illnesses characterized by increased pulmonary arterial pressures leading to right heart failure and death, if untreated. 15-25% of patients have genetic mutations, the most common affecting bone morphogenetic protein receptor type 2 (BMPR2). The aim was to define an inflammatory cytokine profile in BMPR2-mutation positive patients and analyze their influence on survival.MethodsLevels of cytokines were measured in plasma samples from BMPR2-mutation positive patients (BMPR2mut, n=54), patients without any driving mutations (n=54), and healthy controls (n=56) recruited from the United Kingdom cohort.FindingsBMPR2-mutation positive patients and patients without mutations had high levels of interleukin-6, interleukin-8, tumor necrosis factor-α, and vascular endothelial growth factor-A compared to controls. Only BMPR2-mutation carrying patients had higher G-CSF levels compared to controls. VEGF-A levels were substantially higher in patients without mutations compared to the BMPR2mut group. Interleukin-6 was a significant discriminator for mortality in the BMPR2mut cohort (cumulative survival with interleukin-6≥1.6pg/ml at 3 years was 65% compared to 96% with interleukin-6P=0·0013). N-Terminal pro-B-Type natriuretic peptide levels did not discriminate for survival in our BMPR2mut cohort (cumulative survival for patients with an NT-proBNP>130ng/ml at 3 years was 76% compared to 84% for patients with an NT-proBNP≤130ng/ml, P=0·37). NT-proBNP outperformed interleukin-6 in PAH without mutations.InterpretationBMPR2-mutation positivity has a direct impact not only on inflammatory profiles but also on effectiveness of prognostic biomarkers. In our BMPR2-mutation positive cohort IL-6 was the strongest prognostic biomarker and NT-proBNP failed to discriminate for survival.Key messagesWhat is the key question?Do pulmonary arterial hypertension patients who are BMPR2-mutation positive have a different cytokine signature than PAH patients without mutations?What is the bottom line?BMPR2-mutation positive and PAH patients without mutations display different patterns of cytokine elevation and these cytokines differ in the way they influence transplant-free survival.Why read on?In our cohort of BMPR2-mutation positive patients, IL-6 is the best prognostic biomarker while NT-proBNP failed to discriminate for survival – this implies that prognostic biomarkers and by inference treatments could be genotype-specific.Graphical AbstractTAKE HOME MESSAGEBMPR2-mutation positive patients have different inflammatory and growth factor profiles compared to PAH patients without mutations. Interleukin-6 is an effective biomarker for transplant-free survival in our cohort of BMPR2-mutation positive patients while NT-proBNP is ineffective. Conversely, NT-proBNP appears to be a more effective biomarker for pulmonary arterial patients without any mutations.

Transmission of SARS-CoV-2 is uncontrolled in many parts of the world; control is compounded in some areas by the higher transmission potential of the B.1.1.7 variant1, which has now been reported in 94 countries. It is unclear whether the response of the virus to vaccines against SARS-CoV-2 on the basis of the prototypic strain will be affected by the mutations found in B.1.1.7. Here we assess the immune responses of individuals after vaccination with the mRNA-based vaccine BNT162b22. We measured neutralizing antibody responses after the first and second immunizations using pseudoviruses that expressed the wild-type spike protein or a mutated spike protein that contained the eight amino acid changes found in the B.1.1.7 variant. The sera from individuals who received the vaccine exhibited a broad range of neutralizing titres against the wild-type pseudoviruses that were modestly reduced against the B.1.1.7 variant. This reduction was also evident in sera from some patients who had recovered from COVID-19. Decreased neutralization of the B.1.1.7 variant was also observed for monoclonal antibodies that target the N-terminal domain (9 out of 10) and the receptor-binding motif (5 out of 31), but not for monoclonal antibodies that recognize the receptor-binding domain that bind outside the receptor-binding motif. Introduction of the mutation that encodes the E484K substitution in the B.1.1.7 background to reflect a newly emerged variant of concern (VOC 202102/02) led to a more-substantial loss of neutralizing activity by vaccine-elicited antibodies and monoclonal antibodies (19 out of 31) compared with the loss of neutralizing activity conferred by the mutations in B.1.1.7 alone. The emergence of the E484K substitution in a B.1.1.7 background represents a threat to the efficacy of the BNT162b2 vaccine.

Previously, we showed that 3% (31/1032)of asymptomatic healthcare workers (HCWs) from a large teaching hospital in Cambridge, UK, tested positive for SARS-CoV-2 in April 2020. About 15% (26/169) HCWs with symptoms of coronavirus disease 2019 (COVID-19) also tested positive for SARS-CoV-2 (Rivett et al., 2020). Here, we show that the proportion of both asymptomatic and symptomatic HCWs testing positive for SARS-CoV-2 rapidly declined to near-zero between 25th April and 24th May 2020, corresponding to a decline in patient admissions with COVID-19 during the ongoing UK ‘lockdown’. These data demonstrate how infection prevention and control measures including staff testing may help prevent hospitals from becoming independent ‘hubs’ of SARS-CoV-2 transmission, and illustrate how, with appropriate precautions, organizations in other sectors may be able to resume on-site work safely.

Significant differences exist in the availability of healthcare worker (HCW) SARS-CoV-2 testing between countries, and existing programmes focus on screening symptomatic rather than asymptomatic staff. Over a 3 week period (April 2020), 1032 asymptomatic HCWs were screened for SARS-CoV-2 in a large UK teaching hospital. Symptomatic staff and symptomatic household contacts were additionally tested. Real-time RT-PCR was used to detect viral RNA from a throat+nose self-swab. 3% of HCWs in the asymptomatic screening group tested positive for SARS-CoV-2. 17/30 (57%) were truly asymptomatic/pauci-symptomatic. 12/30 (40%) had experienced symptoms compatible with coronavirus disease 2019 (COVID-19)>7 days prior to testing, most self-isolating, returning well. Clusters of HCW infection were discovered on two independent wards. Viral genome sequencing showed that the majority of HCWs had the dominant lineage B∙1. Our data demonstrates the utility of comprehensive screening of HCWs with minimal or no symptoms. This approach will be critical for protecting patients and hospital staff., eLife digest Patients admitted to NHS hospitals are now routinely screened for SARS-CoV-2 (the virus that causes COVID-19), and isolated from other patients if necessary. Yet healthcare workers, including frontline patient-facing staff such as doctors, nurses and physiotherapists, are only tested and excluded from work if they develop symptoms of the illness. However, there is emerging evidence that many people infected with SARS-CoV-2 never develop significant symptoms: these people will therefore be missed by ‘symptomatic-only’ testing. There is also important data showing that around half of all transmissions of SARS-CoV-2 happen before the infected individual even develops symptoms. This means that much broader testing programs are required to spot people when they are most infectious. Rivett, Sridhar, Sparkes, Routledge et al. set out to determine what proportion of healthcare workers was infected with SARS-CoV-2 while also feeling generally healthy at the time of testing. Over 1,000 staff members at a large UK hospital who felt they were well enough to work, and did not fit the government criteria for COVID-19 infection, were tested. Amongst these, 3% were positive for SARS-CoV-2. On closer questioning, around one in five reported no symptoms, two in five very mild symptoms that they had dismissed as inconsequential, and a further two in five reported COVID-19 symptoms that had stopped more than a week previously. In parallel, healthcare workers with symptoms of COVID-19 (and their household contacts) who were self-isolating were also tested, in order to allow those without the virus to quickly return to work and bolster a stretched workforce. Finally, the rates of infection were examined to probe how the virus could have spread through the hospital and among staff – and in particular, to understand whether rates of infection were greater among staff working in areas devoted to COVID-19 patients. Despite wearing appropriate personal protective equipment, healthcare workers in these areas were almost three times more likely to test positive than those working in areas without COVID-19 patients. However, it is not clear whether this genuinely reflects greater rates of patients passing the infection to staff. Staff may give the virus to each other, or even acquire it at home. Overall, this work implies that hospitals need to be vigilant and introduce broad screening programmes across their workforces. It will be vital to establish such approaches before ‘lockdown’ is fully lifted, so healthcare institutions are prepared for any second peak of infections.

INTRODUCTION Only 2.4% of the 16.5-kb mitochondrial DNA (mtDNA) genome shows homoplasmic variation at >1% frequency in humans. Migration patterns have contributed to geographic differences in the frequency of common genetic variants, but population genetic evidence indicates that selection shapes the evolving mtDNA phylogeny. The mechanism and timing of this process are not clear. Unlike the nuclear genome, mtDNA is maternally transmitted and there are many copies in each cell. Initially, a new genetic variant affects only a proportion of the mtDNA (heteroplasmy). During female germ cell development, a reduction in the amount of mtDNA per cell causes a “genetic bottleneck,” which leads to rapid segregation of mtDNA molecules and different levels of heteroplasmy between siblings. Although heteroplasmy is primarily governed by random genetic drift, there is evidence of selection occurring during this process in animals. Yet it has been difficult to demonstrate this convincingly in humans. RATIONALE To determine whether there is selection for or against heteroplasmic mtDNA variants during transmission, we studied 12,975 whole-genome sequences, including 1526 mother–offspring pairs of which 45.1% had heteroplasmy affecting >1% of mtDNA molecules. Harnessing both the mtDNA and nuclear genome sequences, we then determined whether the nuclear genetic background influenced mtDNA heteroplasmy, validating our findings in another 40,325 individuals. RESULTS Previously unknown mtDNA variants were less likely to be inherited than known variants, in which the level of heteroplasmy tended to increase on transmission. Variants in the ribosomal RNA genes were less likely to be transmitted, whereas variants in the noncoding displacement (D)–loop were more likely to be transmitted. MtDNA variants predicted to affect the protein sequence tended to have lower heteroplasmy levels than synonymous variants. In 12,975 individuals, we identified a correlation between the location of heteroplasmic sites and known D-loop polymorphisms, including the absence of variants in critical sites required for mtDNA transcription and replication. We defined 206 unrelated individuals for which the nuclear and mitochondrial genomes were from different human populations. In these individuals, new population-specific heteroplasmies were more likely to match the nuclear genetic ancestry than the mitochondrial genome on which the mutations occurred. These findings were independently replicated in 654 additional unrelated individuals. CONCLUSION The characteristics of mtDNA in the human population are shaped by selective forces acting on heteroplasmy within the female germ line and are influenced by the nuclear genetic background. The signature of selection can be seen over one generation, ensuring consistency between these two independent genetic systems.

- Abstract
Multiple primary tumors (MPTs) affect a substantial proportion of cancer survivors and can result from various causes, including inherited predisposition. Currently, germline genetic testing of MPT-affected individuals for variants in cancer-predisposition genes (CPGs) is mostly targeted by tumor type. We ascertained pre-assessed MPT individuals (with at least two primary tumors by age 60 years or at least three by 70 years) from genetics centers and performed whole-genome sequencing (WGS) on 460 individuals from 440 families. Despite previous negative genetic assessment and molecular investigations, pathogenic variants in moderate- and high-risk CPGs were detected in 67/440 (15.2%) probands. WGS detected variants that would not be (or were not) detected by targeted resequencing strategies, including low-frequency structural variants (6/440 [1.4%] probands). In most individuals with a germline variant assessed as pathogenic or likely pathogenic (P/LP), at least one of their tumor types was characteristic of variants in the relevant CPG. However, in 29 probands (42.2% of those with a P/LP variant), the tumor phenotype appeared discordant. The frequency of individuals with truncating or splice-site CPG variants and at least one discordant tumor type was significantly higher than in a control population (χ2 = 43.642; p ≤ 0.0001). 2/67 (3%) probands with P/LP variants had evidence of multiple inherited neoplasia allele syndrome (MINAS) with deleterious variants in two CPGs. Together with variant detection rates from a previous series of similarly ascertained MPT-affected individuals, the present results suggest that first-line comprehensive CPG analysis in an MPT cohort referred to clinical genetics services would detect a deleterious variant in about a third of individuals.

RC - Abstract
Sex is an important part of life for many people, therefore dealing with erectile problems, living with the effects of physical injury, changes in your appearance or side-effects of treatment can have an enormous impact on your sex life and relationships. Normal sexual behaviour and erectile function depends on a complex interaction between various body-systems, including the brain, nerves, blood-supply and hormones. All of these systems (alone or in combination) may be affected following multiple trauma, traumatic brain injury (TBI) or spinal cord injury (SCI). For men, trauma may result in problems with achieving or maintaining erections (commonly referred to as erectile dysfunction; ED), problems with ejaculation, or how they think/feel about sex - all of these problems may have an indirect, if not profound impact on long-term functional recovery and overall quality of life. Following multiple trauma, spinal injury, or TBI, it is not unusual for some men to go through a period of reduced sexual drive (reduced libido). Apart from physical effects of injury, the way the body responds sexually also depends on thoughts and feelings – thoughts and feelings about yourself and others may be influenced by changes in mood, motivation, personality and thought-processes. This may be complicated by depression, emotional trauma following the injury, medication, or changes in hormone levels. As some men grapple with the changes and implications associated with their injury, many may initially ignore the importance of sexual difficulties, as they remain focused on physical rehabilitation and recovery of mobility. Other men may be reluctant to acknowledge sexual difficulties, due to cultural or personal reasons. There are a wide range of treatments and interventions that may be helpful for the man and his partner, which is why assessment of sexual function should be routinely incorporated into rehabilitation and follow-up services for trauma-survivors. The information below describes common sexual problems after TBI, SCI or multiple trauma and ways to improve sexual functioning.

- Abstract
Spinocerebellar ataxia (SCA) 15/16 is an autosomal dominantly inherited, almost pure cerebellar ataxia, which shows slow or no progression. (It has been designated variably SCA15 and SCA 16; we refer to it here as SCA15/16 to avoid confusion). Deletions in the inositol 1, 4, 5-triphosphate receptor 1 (ITPR1) on chromosome 3 have been shown to cause SCA15/16 in six families worldwide to date, with one further Japanese family identified as having an ITPR1 point mutation. We present a previously unreported SCA15/16 kindred. We describe the clinical phenotype of the family in detail; affected subjects display a remarkably slow, almost pure cerebellar syndrome. We also present genetic analyses for all subjects and longitudinal MRI data for one affected subject. Genetic analysis shows a deletion of 346,487bp in ITPR1 (the second largest ITPR1 deletion reported to date), suggesting SCA15 is due to a loss of ITPR1 function, and western blotting of lymphoblastoid cell line protein confirms reduced ITPR1 protein levels. Serial MRIs show progressive midline cerebellar atrophy with mild inferior parietal and temporal cortical volume loss in the absence of clinical disease progression. We believe that genetic testing for SCA15/16 should become a routine DNA screen available in all Neurogenetics clinics, which is likely to lead to an increased rate of the diagnosis. Familiarity with the phenotype is therefore important for all neurologists.

- Abstract
The purpose of this study was to characterise a novel family with very slowly progressive pure spinocerebellar ataxia (SCA) caused by a deletion in the inositol 1,4,5-triphosphate receptor 1 (ITPR1) gene on chromosome 3. This is a detailed clinical, genetic, and radiological description of the genotype. Deletions in ITPR1 have been shown to cause SCA15/SCA16 in six families to date. A further Japanese family has been identified with an ITPR1 point mutation. The exact prevalence is as yet unknown, but is probably higher than previously thought. The clinical phenotype of the family is described, and videotaped clinical examinations are presented. Serial brain magnetic resonance imaging studies were carried out on one affected individual, and genetic analysis was performed on several family members. Protein analysis confirmed the ITPR1 deletion. Affected subjects display a remarkably slow, almost pure cerebellar syndrome. Serial magnetic resonance imaging shows moderate cerebellar atrophy with mild inferior parietal and temporal cortical volume loss. Genetic analysis shows a deletion of 346,487 bp in ITPR1 (the second largest ITPR1 deletion reported to date), suggesting SCA15 is due to a loss of ITPR1 function. Western blotting of lymphoblastoid cell line protein confirms reduced ITPR1 protein levels. SCA15 is a slowly or nonprogressive pure cerebellar ataxia, which appears to be caused by a loss of ITPR1 function and a reduction in the translated protein. Patients with nonprogressive or slowly progressive ataxia should be screened for ITPR1 defects.

- Abstract
BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is often a sequel of venous thromboembolism with fatal natural history; however, many cases can be cured by pulmonary endarterectomy. The clinical characteristics and current management of patients enrolled in an international CTEPH registry was investigated. METHODS AND RESULTS: The international registry included 679 newly diagnosed (≤6 months) consecutive patients with CTEPH, from February 2007 until January 2009. Diagnosis was confirmed by right heart catheterization, ventilation-perfusion lung scintigraphy, computerized tomography, and/or pulmonary angiography. At diagnosis, a median of 14.1 months had passed since first symptoms; 427 patients (62.9%) were considered operable, 247 (36.4%) nonoperable, and 5 (0.7%) had no operability data; 386 patients (56.8%, ranging from 12.0%- 60.9% across countries) underwent surgery. Operable patients did not differ from nonoperable patients relative to symptoms, New York Heart Association class, and hemodynamics. A history of acute pulmonary embolism was reported for 74.8% of patients (77.5% operable, 70.0% nonoperable). Associated conditions included thrombophilic disorder in 31.9% (37.1% operable, 23.5% nonoperable) and splenectomy in 3.4% of patients (1.9% operable, 5.7% nonoperable). At the time of CTEPH diagnosis, 37.7% of patients initiated at least 1 pulmonary arterial hypertension-targeted therapy (28.3% operable, 53.8% nonoperable). Pulmonary endarterectomy was performed with a 4.7% documented mortality rate. CONCLUSIONS: Despite similarities in clinical presentation, operable and nonoperable CTEPH patients may have distinct associated medical conditions. Operability rates vary considerably across countries, and a substantial number of patients (operable and nonoperable) receive off-label pulmonary arterial hypertension-targeted treatments.

RC - Abstract
The nature and severity of a man’s neurological condition may have a profound effect on erectile function and this warrants careful consideration in relation to providing supportive treatment options that are effective, safe and acceptable for the individual and his partner. Neurological disorders contribute to erectile dysfunction (ED) in a number of different ways and may occur as a direct result of impairment in the central nervous system, the peripheral nervous system, or a combination of both. Functional loss associated with the condition itself and subsequent damage to CNS structures (including spinal tracts, cerebral cortex, spinal cord or the autonomic nerves), may reduce the capacity to physically experience genital sensation, engage in physical intimacy and achieve erection, normally associated with sexual intercourse. In most neurological disorders, comorbid depression, altered body image, and the prescription of various medicines used to manage symptoms such as pain, spasticity, continence (amongst others) may nefariously contribute to patient’s psychological wellbeing, negatively impact on quality of life and affect relationships. Nurses are ideally placed to assess the relative impact of the neurological condition and the effects of various treatments on erectile function. Proactively addressing patients’ sexuality and making it a natural part of holistic nursing care allows for early detection of any problems that otherwise would go unidentified. Availability of guidelines & information about how to access various treatments for ED may be useful in all neurological care units, so that nurses and other health professionals are adequately equipped to provide appropriate information, reassurance and acceptable treatment interventions. Decisions regarding selection of specific treatments should take into account the preferences and expectations of patient and his partner. As first-line therapy and in the absence of contraindications to their use, conventional treatments such as the phosphodiesterase-5 inhibitors (PDE5Is) have been shown to significantly improve erectile function. Taking into account the patient’s mobility, dexterity and ability to self-administer, other treatments such as intracavernosal injections, medicated urethral system for erection (MUSE) and the use of vacuum constriction devices (VCDs) may be reserved for patients who do not have a response to PDE5Is, or in whom these drugs are poorly tolerated, or contraindicated. Psychosexual counselling may be helpful in cases of erectile dysfunction with psychological needs or relationship difficulties. This talk begins by focusing on the neurobiology of sexual arousal and the biological basis for erectile dysfunction in men with a variety of neurological disorders, including stroke, MS, Parkinson’s disease, Epilepsy, autonomic dysfunction and spinal cord injury (SCI). After considering the range of problems men typically experience with ED secondary to neurological impairment, we will discuss the relative benefits of various treatment options and current guidelines and good clinical practice for management of ED.

EIF2AK4 ,pulmonary venoocclusive disease ,pulmonary hypertension ,genetics ,human ,prognosis ,3. Good health - Abstract
BACKGROUND: Pulmonary arterial hypertension (PAH) is a rare disease with an emerging genetic basis. Heterozygous mutations in the gene encoding the bone morphogenetic protein receptor type 2 (BMPR2) are the commonest genetic cause of PAH, whereas biallelic mutations in the eukaryotic translation initiation factor 2 alpha kinase 4 gene (EIF2AK4) are described in pulmonary veno-occlusive disease and pulmonary capillary haemangiomatosis (PVOD/PCH). Here, we determined the frequency of these mutations and define the genotype-phenotype characteristics in a large cohort of patients diagnosed clinically with PAH. METHODS: Whole genome sequencing was performed on DNA from patients with idiopathic and heritable PAH, as well as PVOD/PCH recruited to the NIHR BioResource - Rare Diseases Study. Heterozygous variants in BMPR2 and biallelic EIF2AK4 variants with a minor allele frequency of < 1:10,000 in control data sets and predicted to be deleterious (by CADD, PolyPhen-2 and SIFT predictions) were identified as potentially causal. Phenotype data from the time of diagnosis were also captured. RESULTS: Eight hundred and sixty-four patients with idiopathic or heritable PAH and 16 with PVOD/PCH were recruited. Mutations in BMPR2 were identified in 130 patients (14.8%). Biallelic mutations in EIF2AK4 were identified in 5 patients with a clinical diagnosis of PVOD/PCH. Furthermore, 9 patients with a clinical diagnosis of PAH carried biallelic EIF2AK4 mutations. These patients had a reduced transfer coefficient for carbon monoxide (KCO: 33 [IQR: 30 - 35] % predicted) and younger age at diagnosis (29 [23 - 38] years) as well as more interlobular septal thickening and mediastinal lymphadenopathy on computed tomography of the chest, compared to PAH patients without EIF2AK4 mutations. However, radiological assessment alone could not accurately identify biallelic EIF2AK4 mutation carriers. PAH patients with biallelic EIF2AK4 mutations had a shorter survival. CONCLUSIONS: Biallelic EIF2AK4 mutations are found in patients classified clinically as idiopathic and heritable PAH. These patients cannot be identified reliably by CT, but a low KCO and a young age of diagnosis suggests the underlying molecular diagnosis. Genetic testing can identify these misclassified patients, allowing appropriate management and early referral for lung transplantation., The National Institute of Health Research (NIHR) BioResource for Rare Diseases provided funding for sequencing and analysis. The study was supported by a British Heart Foundation Special Project Grant and a Medical Research Council (UK) Experimental Challenge Award.

Introduction and Objectives Markers of immune activation and inflammation are raised in pulmonary arterial hypertension; the degree of elevation of levels of pro-inflammatory cytokines in idiopathic pulmonary arterial hypertension has recently been shown to predict long term survival (Soon et al, Circulation, 2010). Much less is known of the role of cytokines in disease monitoring. We assessed levels of serum cytokines in patients at initial assessment prior to commencement of targeted therapy for pulmonary hypertension, and when the patient returned to the hospital for follow-up. We also examined if changes in serum cytokines correlated with changes in 6-min walk test (6MWT). Methods 19 patients with a diagnosis of Group I PAH or Group IV chronic thromboembolic pulmonary hypertension in a distribution inaccessible to surgery were included. Patients with inflammatory conditions other than an associated connective tissue disease or a musculoskeletal condition that would interfere with the 6MWT were excluded. 11 healthy volunteers acted as a control group. Serum levels of interleukin (IL) 1β, 2, 4, 6, 8, 10, 12p70 and tumour necrosis factor α (TNFα) were measured using a multiplex analyser. A Wilcoxon matched pairs test was used to compare differences between baseline and follow-up samples. Results Patient and control demographics are presented in the Abstract P3 table 1. Levels of IL 2,6,8,10 and TNFα were elevated in the patient group compared to controls. Average time to repeat patient sampling was 4.7±1.8 months. There were no significant differences between the levels of any cytokines between baseline and follow-up in the patients and no overall correlation existed between change in 6MWT and change in any cytokine. When patients who had improved their 6MWT on follow-up were analysed as a separate group, there was a significant (p=0.0068) drop in IL6 levels on follow-up. Conclusions Several cytokines were elevated in these patients with pulmonary hypertension. The role of cytokines in disease monitoring requires further study and there seems to be little relation with serum cytokines, except IL6, and a change in a patient's clinical state as measured by 6MWT. Replication of results from this pilot study and examination of longitudinal trends in cytokine levels are warranted. [ABSTRACT FROM AUTHOR]

PULMONARY hypertension , *DATA mapping , *DATA analysis - Abstract
Introduction Pulmonary endarterectomy (PEA) is the treatment of choice for patients with proximal chronic thromboembolic pulmonary hypertension (CTEPH). The UK has a single centre performing this operation and the program became nationally funded since 2000. Patients are referred from seven specialist pulmonary hypertension centres. Method All 625 patients treated with PEA from 2000 to 2010 were mapped according to their home postcode at the time of PEA surgery. Primary care trusts (PCT's) were assigned from these home postcodes. The incidence rate of each PCT and overall incidence were analysed. Map info software was used to generate the referral maps. Results The new patient incidence ranges from no referrals in 123 PCT's in 2000-2002 to 90 in 2008-2010. The most recent period shows highest referral rates for PEA. From our PEA data mapping analysis we have calculated that the incidence of operated patients was 0.4 million population in 2000 (n=22) and 2 per million population in 2010 (n=122). Conclusion There has been a fivefold increase in PEA activity in the UK over the last decade. The analysis of our data are limited to surgical cases. The current incidence of PEA in the UK is already higher than historical estimation of the incidence of all CTEPH (0.1-0.5/million, Fedullo, N Engl J Med 2001). Since 30% of patients with CTEPH have distal disease distribution and some patients with proximal CTEPH do not proceed to surgery due to choice or comorbidities, the overall incidence of CTEPH is likely to be significantly higher than 2 per million/year and higher than previously suspected.
