Abstract
Background Phospholipase A2 receptor-associated membranous nephropathy (PLA2R-MN) is an anti-PLA2R antibody (PLA2R-Ab) mediated autoimmune kidney disease. Although antibody titer correlates closely with disease activity, whether it can provide longer-term predictions on disease course and progression is unclear. Rituximab, a B-cell depletion therapy, has become the first-line treatment option for PLA2R-MN; however, the response to Rituximab varies among patients. Methods We developed a flow cytometry-based test that detects and quantifies PLA2R antigen-specific memory B cells (PLA2R-MBCs) in peripheral blood, the primary source for PLA2R-Ab production upon disease relapse. We applied the test to 159 blood samples collected from 28 patients with PLA2R-MN (at diagnosis, during and after immunosuppressive treatment, immunological remission, and relapse) to evaluate the relationship between circulating PLA2R-MBC levels and disease activity. Results The level of PLA2R-MBCs in healthy controls (n=56) is less than or equal to 1.5% of the total MBC compartment. High circulating PLA2R-MBC levels were detected in two patients post-Rituximab despite achieving immunologic and proteinuric remission, as well as in two patients with negative serum autoantibody but increasing proteinuria. Elimination of these cells with Rituximab improved clinical outcomes. Moreover, five patients exhibited elevated PLA2R-MBC levels before disease relapse, followed by a rapid decline to baseline when relapse became clinically evident. COVID-19 vaccination or SARS-CoV-2 infection significantly affected the dynamics of circulating PLA2R-MBCs. Conclusions This study suggests that monitoring PLA2R-MBC levels in patients with PLA2R-MN may help refine and individualize immunosuppressive therapy and predict disease course and progression. The technology and findings may also have broader applications in the clinical management of other autoimmune diseases.

Abstract
Key Points IgAN and MCD are the most common de novo glomerular diseases reported after COVID-19 vaccination, particularly after mRNA vaccination. Membranous nephropathy, pauci-immune GN, and collapsing GN have also been attributed to COVID-19 vaccination, some with dual histologies. Recovery of kidney function and proteinuria remission is more likely in IgAN and MCD by 4–6 months compared with the other glomerular diseases. Background Patients with de novo glomerular disease (GD) with various renal histologies have been reported after vaccination against SARS-CoV-2. Causality has not been established, and the long-term outcomes are not known. To better characterize the GDs and clinical courses/outcomes, we created the International Registry of COVID-19 vaccination and Glomerulonephritis to study in aggregate patients with de novo GN suspected after COVID-19 vaccine exposure. Methods A REDCap survey was used for anonymized data collection. Detailed information on vaccination type and timing and GD histology were recorded in the registry. We collected serial information on laboratory values (before and after vaccination and during follow-up), treatments, and kidney-related outcomes. Results Ninety-eight patients with GD were entered into the registry over 11 months from 44 centers throughout the world. Median follow-up was 89 days after diagnosis. IgA nephropathy (IgAN) and minimal change disease (MCD) were the most common kidney diseases reported. Recovery of kidney function and remission of proteinuria were more likely in IgAN and MCD at 4–6 months than with pauci-immune GN/vasculitis and membranous nephropathy. Conclusions The development of GD after vaccination against SARS-CoV-2 may be a very rare adverse event. Temporal association is present for IgAN and MCD, but causality is not firmly established. Kidney outcomes for IgAN and MCD are favorable. No changes in vaccination risk-benefit assessment are recommended based on these findings.

Abstract
Abstract
Background
Normal mean pulmonary artery pressure (mPAP) does not exceed 20 mmHg and normal pulmonary vascular resistance (PVR) does not exceed 2 Wood Units (WU). The thresholds used to define pre-capillary pulmonary hypertension (PH) – mPAP ≥25 mmHg and PVR >3 WU – are being evaluated. It is unclear if treatment would benefit patients with mildly elevated mPAP (≥21–<25 mmHg).
Purpose
The EVIDENCE-PAH study aims to describe mortality and hospitalisation outcomes, clinical characteristics, therapies, and quality of life during long-term follow-up of a national cohort of patients with different levels of mPAP and PVR. We report preliminary analyses focusing on mortality and its cause in patients stratified by their baseline (BL) mPAP.
Methods
This retrospective analysis included PAH-treatment-naïve patients with suspected PH who received a first right heart catheterisation (RHC) between 2009 and 2017 at any of the 7 UK tertiary PH centres, which assess all PH patients in the UK. A sample of patients with BL mPAP ≥25 mmHg (stratified by PVR and treatable versus non-treatable PH) was used as a control in this analysis. Baseline characteristics, mortality and cause of mortality were stratified by mPAP (<21, ≥21–<25, ≥25 mmHg) at BL (first RHC). Mortality was also stratified by BL PVR (<1, 1–<2, 2–<3, 3–<6, ≥6 WU). Mortality analysis was done without matching cohorts. Mortality data were obtained from the Office for National Statistics, NHS Digital.
Results
In total, 2926 patients were analysed (968, 689 and 1269 with mPAP <21, ≥21–<25, ≥25 mmHg, respectively). Mean observation was 6.1 years. BL characteristics are in Table. Survival worsened with increasing mPAP (p<0.0001) and increasing PVR (p<0.01) (Figure). After 5 years of follow-up, 187 (27.1%) patients with mPAP ≥21–<25 mmHg had died, compared with 162 (16.7%) and 595 (46.9%) patients in the lower and higher mPAP groups, respectively. In patients with mPAP ≥21–<25 mmHg, the most common main cause of death was respiratory disease (36.4%) – with scleroderma lung disease and interstitial lung disease accounting for 69.1% of these deaths – followed by cardiac disease (16.6%) and malignancy (15.0%) (Table). PH was the main cause of death for only 1.6% of patients with mildly elevated mPAP and it was a contributor to death in 6.8% (BL mPAP <21 mmHg), 10.2% (≥21–<25 mmHg), and 40.2% (≥25 mmHg) of cases.
Conclusion
Long-term survival in patients with mPAP ≥21–<25 mmHg was worse than in those with normal mPAP, and better than in those with the current definition of PH. While the main cause of death was mostly unrelated to PH and further analysis is needed to understand the impact of underlying disease, mildly elevated mPAP appears to confer a worse prognosis and should be closely monitored. These data show the relevant disease burden in patients with mPAP ≥21–<25 mmHg and the need to understand if they could benefit from treatment. PVR may be key in determining patients who might benefit.

Abstract
BACKGROUND Incisional hernias cause morbidity and may require further surgery. HART (Hughes Abdominal Repair Trial) assessed the effect of an alternative suture method on the incidence of incisional hernia following colorectal cancer surgery. METHODS A pragmatic multicentre single-blind RCT allocated patients undergoing midline incision for colorectal cancer to either Hughes closure (double far-near-near-far sutures of 1 nylon suture at 2-cm intervals along the fascia combined with conventional mass closure) or the surgeon's standard closure. The primary outcome was the incidence of incisional hernia at 1 year assessed by clinical examination. An intention-to-treat analysis was performed. RESULTS Between August 2014 and February 2018, 802 patients were randomized to either Hughes closure (401) or the standard mass closure group (401). At 1 year after surgery, 672 patients (83.7 per cent) were included in the primary outcome analysis; 50 of 339 patients (14.8 per cent) in the Hughes group and 57 of 333 (17.1 per cent) in the standard closure group had incisional hernia (OR 0.84, 95 per cent c.i. 0.55 to 1.27; P = 0.402). At 2 years, 78 patients (28.7 per cent) in the Hughes repair group and 84 (31.8 per cent) in the standard closure group had incisional hernia (OR 0.86, 0.59 to 1.25; P = 0.429). Adverse events were similar in the two groups, apart from the rate of surgical-site infection, which was higher in the Hughes group (13.2 versus 7.7 per cent; OR 1.82, 1.14 to 2.91; P = 0.011). CONCLUSION The incidence of incisional hernia after colorectal cancer surgery is high. There was no statistical difference in incidence between Hughes closure and mass closure at 1 or 2 years.

Abstract
BACKGROUND Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. OBJECTIVES We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. METHODS A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. RESULTS Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. CONCLUSIONS In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Abstract
Introduction Few studies have explored ethnic inequalities in physical and mental health in women at preconception. Objectives Explore inequalities in multimorbidity in women of reproductive age. Methods Data from Lambeth DataNet, anonymized primary care records of this ethnically diverse London borough, linked to anonymized electronic mental health records (“CRIS secondary care database”) were extracted on preconception risk factors including BMI, smoking, alcohol, substance misuse, micronutrient deficiencies and physical health diagnoses for women aged 15-40 with an episode of secondary mental health care (January 2008-December 2018) and no pregnancy codes (n=3,633) and a 4:1 age-matched comparison cohort (n=14,532) . Results Women in contact with mental health services (whether with or without SMI diagnoses) had a higher prevalence of all risk factors and physical health diagnoses studied after adjustment for deprivation and ethnicity. Women from minority ethnic groups [79.5% of total sample] were less likely to be diagnosed with depression in primary care compared to White British women [adj OR 0.66 (0.55- 0.79) p<0.001] and Black women were more likely to have a severe mental illness [adj OR 3.41(2.63-4.43), p<0.001]. Black and Asian women were less likely to smoke or misuse substances and more likely to be vitaminD deficient. Black women were also significantly more likely to be overweight [adj OR 4.56(3.96-5.24 p <0.001] and have two or more physical health conditions [adj OR 2.98(2.19-4.07) p<0.001] than White British women after adjustment for deprivation and SMI diagnoses. Conclusions Our results highlight a need for culturally centered integrative models of care across primary and secondary mental health services.

Abstract
Introduction Best practice requires the treating physician to understand the needs and hopes of his/her patient, particularly in relation to pregnancy and childbirth preferences. This is even more necessary for women with Severe Mental Illness (SMI) because of the complicated decisions they face balancing the need to continue medication in pregnancy to prevent relapse against any possible harm to the foetus. Objectives: To explore what women themselves view as most important when discussing pregnancy and childbirth with psychiatrists and what barriers there are to a) having a meaningful conversation and b) achieving optimum outcomes. Qualitative methods were used to analyse the data from in-depth interviews with 21 women, recruited from a South London NHS organisation (76%) and the UK’s national bipolar charity (24%). The views of 25 health professionals, including 19 psychiatrists, were also collected and analysed. Results: Many themes emerged but principally women wanted: information, continuity of care, better training for health professionals, to co-produce a detailed care plan, access to a Mother and Baby Unit, peer support and more research on medications in pregnancy. Conclusions: This study highlighted the importance of understanding women’s needs and fears and giving them the necessary information to make the difficult decisions that face them. Such understanding is likely to lead to more positive therapeutic relationships and better long-term outcomes. Disclosure No significant relationships.

Abstract
We discovered a highly virulent variant of subtype-B HIV-1 in the Netherlands. One hundred nine individuals with this variant had a 0.54 to 0.74 log10 increase (i.e., a ~3.5-fold to 5.5-fold increase) in viral load compared with, and exhibited CD4 cell decline twice as fast as, 6604 individuals with other subtype-B strains. Without treatment, advanced HIV-CD4 cell counts below 350 cells per cubic millimeter, with long-term clinical consequences-is expected to be reached, on average, 9 months after diagnosis for individuals in their thirties with this variant. Age, sex, suspected mode of transmission, and place of birth for the aforementioned 109 individuals were typical for HIV-positive people in the Netherlands, which suggests that the increased virulence is attributable to the viral strain. Genetic sequence analysis suggests that this variant arose in the 1990s from de novo mutation, not recombination, with increased transmissibility and an unfamiliar molecular mechanism of virulence.

Abstract
Background The acute and long-term effects of severe acute respiratory syndrome coronavirus 2 infection in individuals with GN are still unclear. To address this relevant issue, we created the International Registry of COVID-19 infection in GN. Methods We collected serial information on kidney-related and -unrelated outcomes from 125 GN patients (63 hospitalized and 62 outpatients) and 83 non-GN hospitalized patients with coronavirus disease 2019 (COVID-19) and a median follow-up period of 6.4 (interquartile range 2.3-9.6) months after diagnosis. We used logistic regression for the analyses of clinical outcomes and linear mixed models for the longitudinal analyses of eGFR. All multiple regression models were adjusted for age, sex, ethnicity, and renin-angiotensin-aldosterone system inhibitor use. Results After adjustment for pre-COVID-19 eGFR and other confounders, mortality and AKI did not differ between GN patients and controls (adjusted odds ratio for AKI=1.28; 95% confidence interval [CI], 0.46 to 3.60; P=0.64). The main predictor of AKI was pre-COVID-19 eGFR (adjusted odds ratio per 1 SD unit decrease in eGFR=3.04; 95% CI, 1.76 to 5.28; P<0.001). GN patients developing AKI were less likely to recover pre-COVID-19 eGFR compared with controls (adjusted 6-month post-COVID-19 eGFR=0.41; 95% CI, 0.25 to 0.56; times pre-COVID-19 eGFR). Shorter duration of GN diagnosis, higher pre-COVID-19 proteinuria, and diagnosis of focal segmental glomerulosclerosis or minimal change disease were associated with a lower post-COVID-19 eGFR. Conclusions Pre-COVID-19 eGFR is the main risk factor for AKI regardless of GN diagnosis. However, GN patients are at higher risk of impaired eGFR recovery after COVID-19-associated AKI. These patients (especially those with high baseline proteinuria or a diagnosis of focal segmental glomerulosclerosis or minimal change disease) should be closely monitored not only during the acute phases of COVID-19 but also after its resolution.

Abstract
Introduction There is little prospective data on the risk factors for later suicide in women who experience perinatal mental disorders, particularly beyond one-year postnatal. Objectives Among a cohort of women who were in contact with a mental healthcare provider during the perinatal period, to: (1) Describe sociodemographic and clinical characteristics of the women who died by suicide (2) Understand when, in relation to childbirth, most suicides tended to occur. Methods Data-linkage of de-identified service-user electronic healthcare records, national hospital episode statistics and mortality data generated a cohort of women in contact with a mental healthcare service provider in London, UK, perinatally. Using Natural Language Processing and structured field extraction, we identified clinical, socio-demographic characteristics, self-harm exposure, and suicide. Results Among 5204 women, clinical and demographic characteristics of women who did and did not die by suicide were similar apart from indicators of illness severity including perinatal sedative medication prescription, clinician-rated functional impairment and smoking, which were more common in women who died by suicide. Suicide deaths occurred most frequently in the second year post-delivery. The most common method of suicide ocurring wihtin two years was by violent means, whereas after two years postnatal, the most common method was non-violent. Conclusions Our findings support the extension of perinatal mental healthcare service provision to two years post-delivery. Disclosure No significant relationships.

Abstract
Abstract
Background
Proactive patient monitoring is of paramount importance in effective management of heart failure (HF) patients. Cardiac implantable electronic devices (CIEDs) used in HF patients are able to derive long-term trends in physiologic parameters and provide timely warning to clinicians. Little is known, however, on the real-world experience with device-generated HF risk-stratifying algorithms.
Purpose
Heart Failure Risk Score (HFRS) takes into account nine parameters and is calculated automatically based on long-term clinical trends. Remote transmissions provide information on the risk of HF event in next 30 days categorized as low, medium or high based on a maximum daily risk status in prior 30 days. We aimed to evaluate the ability of HFRS to alert HF specialists on the actual HF risk status.
Methods
The prospective registry included all patients with CIEDs featuring integrated Heart Failure Risk Score (HFRS) followed via Medtronic CareLink remote monitoring system and enabled for Co-management (CM) from May 2015 to August 2019 in a tertiary centre. High HFRS does not trigger automatic alert transmission. Study follow-up spanned between start of CM and last transmission in 2019. Inclusion criteria were CRT-D in situ, active Home Monitor, switched on OptiVol 2.0 remote alert and transmission data available on CareLink following study period completion. Transmissions were scheduled 3-monthly.
Results
Out of 229 consecutive patients, 132 met study criteria. Mean age was 74±10 years, 18% were female. Median follow-up duration was 2.7 years (IQR 1.3). Total number of transmissions was 2652, median per patient was 18 (IQR 13); scheduled, unscheduled and care alerts constituted 42%, 44% and 14%, respectively. One third of transmissions were automatically sent for CM review. There were 398 high HFRS episodes. OptiVol fluid index was below the threshold throughout 128 (32%) episodes. Missed episodes (not transmitted within 30 days from the final day of high HFRS) amounted to 130 (33%) and the reasons behind this included OptiVol alerting before the first day of high HFRS or persistently elevated when HFRS changed from low/medium to high (52%), low OptiVol index during the episode (38%) or other (10%). Median duration of high HFRS was 7 days (IQR 12, range, 1–187). Among timely picked-up high HFRS episodes, 38% were transmitted during the relevant episode and 62% afterwards with median delay of 10 days (IQR 15) from the last day of high HFRS; 21% of transmissions showing high HFRS were not highlighted for CM review which correlated with low OptiVol index, P<0.001. The factors contributing to high HFRS included: raised OptiVol (60%), patient activity (83%), AT/AF (46%), ventricular rate (VR) during AF (6%), % of VP (40%), shocks (2%), treated VT/VF (2%), night VR (72%) and HR variability (34%).
Conclusions
In a real-world clinical setting high HFRS was frequently under-reported. The investigation into clinical implications is warranted.

Abstract
Abstract
Background
Primary mitral regurgitation (MR) is one of the most common heart valvular pathologies. However, optimum timing of surgery remains controversial.
Purpose
To describe changes in cardiopulmonary exercise testing (CPET) parameters after surgery for severe primary MR.
Methods
In a single centre prospective study, patients undergoing surgery under current ESC guidelines for severe primary MR underwent assessment with transthoracic echocardiogram, CPET, cardiac MRI and quality of life questionnaire pre-operatively and at six months after surgery. The primary outcome was a per protocol analysis of impaired post-operative functional capacity (defined as post-operative left ventricular ejection fraction on transthoracic echocardiogram <50% and/or post-operative percentage predicted peak VO2 ≤84%).
Results
43 of the 50 patients recruited between February 2017 and October 2018 were included in the per protocol analysis. Thirty five patients (72.9%) had impaired post-operative functional capacity. In the overall cohort (n=43), there was a significant fall post-operatively in percentage predicted peak VO2 (ppVO2) (81.8±15.7% vs. 76.2±16.2%, p<0.01) and anaerobic threshold (AT) (48.0±11.1% vs. 44.3±10.1%, p=0.01). In patients with a class I indication for surgery (n=30), there was no significant change post-operatively in ppVO2 (79.6±15.7% vs. 75.6±16.7%, p=0.09) or AT (49.9±11.4% vs. 46.4±10.2%, p-0.09). However, in patients with a class II indication for surgery (n=13), there was a significant change post-operatively in ppVO2 (86.9±15.1% vs. 77.4±15.9%, p<0.01), but not in AT (43.5±9.6% vs. 39.5±8.3%, p=0.16).
In the multivariable analysis, pre-operative left ventricular ejection fraction ≤60% (hazard ratio, 1.69; 95% confidence interval, 1.56 to 480.1, p=0.04) and pre-operative percentage predicted peak VO2 ≤84% (hazard ratio, 1.22; 95% confidence interval, 2.13 to 107.1, p<0.01) were independent predictors for impaired post-operative functional capacity.
Conclusions
Pre-operative percentage predicted peak VO2 ≤84% is an independent predictor of impaired post-operative functional capacity. Subject to a confirmatory study, this may help to refine current ESC guidelines for intervention for severe primary MR.
Change in ppVO2 after surgery

Abstract
Abstract
Background
Pulmonary arterial hypertension (PAH) is a severe disease that progressively leads to right ventricular (RV) failure and cardiovascular death. Evaluation of right heart mechanics by means of 2-dimensional speckle tracking echocardiography (2D-STE) has displayed to be a promising tool to estimate prognosis in PAH patients.
Purpose
To evaluate the association between right ventricular free wall longitudinal strain (RVFWLS) and right peak atrial longitudinal strain (RPALS) at follow-up after initiation of specific vasodilator therapy in PAH patients, with outcomes.
Methods
83 subjects diagnosed with PAH Group 1 at three University Hospitals (Hammersmith Hospital, London, United Kingdom; Trieste University Hospital, Trieste, Italy; FTGM, Pisa, Italy), who were naive from specific treatment for PAH at the time of diagnosis, were retrospectively enrolled in this study. Standard echocardiographic parameters were collected. Outcomes were defined as the combination of all-cause mortality, hospitalization for PAH and first prostanoid administration. We investigated the correlation between RVFWLS and RPALS with outcomes adjusting for validated echocardiographic parameters strongly associated with prognosis in PAH (right atrial area – RAA and pericardial effusion – PE) and patients’ haemodynamics.
Results
30 patients experienced outcomes during a median follow-up time of 33 months. Median RVFWLS at follow-up was -15.8% (IQR: -12.1%/- 21.1%). Median RPALS at follow-up was 25% (IQR: 17.9%/36.6%). In the multivariate analysis, RVFLWS at follow-up was independently associated with outcomes (95% confidence interval [CI]: 1.01 – 1.24, p = 0.04), irrespectively from RAA (95% CI: 0.98 – 1.20, p = 0.12) and pulmonary arterial systolic pressure (PASP, 95% CI: 0.99 – 1.06, p = 0.12). We also observed a trend towards superiority of RPALS at follow-up (95% CI 0.90 – 1.00, p = 0.07) over RAA (95% CI: 0.98 – 1.20, p = 0.14) and PASP (95% CI: 0.99 - 1.05, p= 0.31). Finally, RPALS (95% CI: 0.88 – 1.00, p = 0.05) was independently associated with outcomes over PE (95% CI: 0.14 – 1.89, p = 0.32) and RVFWLS (95% CI: 0.97 – 1.20, p = 0.16).
Conclusions
In PAH group 1, assessment of both RVFWLS and RPALS at follow-up is associated with outcomes, independently from standard echocardiographic parameters.

Abstract
BACKGROUND In adults with primary focal segmental glomerulosclerosis (FSGS), daily prednisone may induce complete remissions (CR) and partial remissions (PR), but relapses are frequent and adverse events are common. METHODS We carried out 2 open-label, uncontrolled trials to explore the efficacy and tolerability of pulse oral dexamethasone as an alternative to daily prednisone. We enrolled adult patients with proteinuria > 3.5 g/day despite the use of renin-angiotensin-aldosterone blockade. In the first trial, we enrolled 14 subjects with FSGS and administered 4 dexamethasone doses (25 mg/m2) daily for 4 days, repeated every 28 days over 32 weeks. The second trial involved a more intensive regimen. Eight subjects received 4 dexamethasone doses of 50 mg/m2 every 4 weeks for 12 weeks, followed by 4 doses of 25 mg/m2 every 4 weeks for 36 weeks; subjects were randomized to 2 doses every 2 weeks or 4 doses every 4 weeks. RESULTS In the first trial, we enrolled 13 subjects with FSGS and 1 with minimal change disease and found a combined CR and PR rate of 36%. In the second trial, we enrolled 8 subjects. The combined CR and PR rate was 29%. Analysis combining both trials showed a combined CR and PR rate of 33%. Adverse events were observed in 32% of subjects, with mood symptoms being most common. There were no serious adverse events related to the study. CONCLUSION We conclude that high dose oral dexamethasone is well tolerated by adults with idiopathic nephrotic syndrome and may have some efficacy.

Abstract
OBJECTIVE This study was designed to understand the level of familiarity of US rheumatologists, gastroenterologists and dermatologists with biosimilar therapies, their experience with non-medical switching (switching medications for reasons unrelated to patient health) of patients between biologics and their attitudes towards switching from a biologic to a biosimilar. METHODS A total of 297 US physicians who currently prescribe biologics for their patients completed a 15-minute online survey. Rheumatologists, dermatologists and gastroenterologists were included. RESULTS The majority of physicians (84%) did not want stable patients undergoing a non-medical switch to a biosimilar. While 60% of physicians believed non-medical switching to biosimilars may have a positive impact on healthcare system costs, multiple negative impacts were also expected. A majority of physicians anticipated a negative impact on patient mental health (59%), treatment efficacy (57%), patient safety (53%) and physician office management (60%). CONCLUSIONS The majority of physicians had concerns regarding non-medical switching to biosimilars and the impact such switching would have on patient care and physician practice.

Abstract
OBJECTIVE To evaluate patient attitudes regarding non-medical switching (NMS) to biosimilars among patients with autoimmune disease currently receiving a biologic. METHODS An online survey was conducted among patients meeting the following criteria: ≥18 years of age; residing in the US; diagnosis of rheumatoid arthritis, Crohn's disease, ulcerative colitis, psoriasis or psoriatic arthritis; currently taking a biologic; and consenting to participate. Patients answered questions about their attitudes and experiences related to NMS. Descriptive statistics were used to summarize responses. RESULTS A total of 1696 patients completed the 20-min survey. Eighty-five per cent of patients were concerned that biosimilars wouldn't treat their disease as well; 85% didn't want to switch to a biosimilar if their current biologic was helping their disease; and 83% were concerned that switching may cause more side-effects. Twenty per cent of patients had previously received notification about a potential NMS to another biologic (that was not a biosimilar) from their insurance company. Of these, 79% took at least one action to avoid the NMS and 45% ultimately switched. Of these patients (n = 150), 67% indicated that their previous biologic worked well for them and 70% didn't want to switch to another biologic. Most patients who switched (67%) did so to avoid paying a higher cost. More than half (56%) went without therapy for administrative reasons during the period of transition from the old biologic to the other treatment. CONCLUSIONS Patients reported multiple concerns about NMS that might impact treatment outcomes, and many of the patients who non-medically switched in this survey missed treatments. Future studies should be conducted on patient expectations and experiences with NMS to understand the impact on healthcare delivery, treatment persistency, and patient outcomes. The patient perspective and experience should be considered by decision-makers when developing coverage policies for biosimilar medications and associated communication strategies.

Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) is an uncommon condition with progressive heart failure and premature death. Treatment costs up to £120,000 per patient per year, and the psychological burden of PAH is substantial. Mindfulness-based stress reduction (MBSR) is an intervention with the potential to reduce this burden, but to date, it has not been applied to people with pulmonary hypertension. We wished to determine whether a trial of MBSR for people with PAH would be feasible. METHODS A customised gentle MBSR programme of eight sessions was developed for people with physical disability due to PAH, and they were randomised to group-based MBSR or treatment as usual. The completeness of outcome measures including Beck Anxiety Index, Beck Depression Inventory and standard physical assessment at 3 months after randomisation were recorded. Health care utilisation was measured. Attendance at the sessions and the costs involved in delivering the intervention were assessed. Semi-structured interviews were conducted to explore the acceptability of the MBSR intervention and when appropriate the reasons for trial non-participation. RESULTS Fifty-two patients were recruited, but only 34 were randomised due to patients finding it difficult to travel to sessions. Twenty-two completed all questionnaires and attended all clinics, both routine and additional in order to collect outcomes measures. The MSBR sessions were delivered in Bristol, Cardiff and London, costing, on average, between £2234 (Cardiff) and £4128 (London) per patient to deliver. Attendance at each session averaged between two patients in Bristol and Cardiff and three in London. For those receiving treatment as usual, clinician blinding was achievable. Interviews revealed that people who attended MBSR found it interesting and helpful in managing their symptoms and minimising the psychological component of their disease. CONCLUSIONS We found that attendance at group MBSR was poor in people with chronic PAH within the context of a trial. Achieving better MBSR intervention attendance or use of an Internet-based programme might maximise the benefit of MBSR.

Abstract
Aims and methodWe explored sociodemographic and clinical factors associated with obtaining employment for people with severe mental illness. Standardised validated interviews and questionnaires were administered to participants who had been recruited into a randomised controlled trial of supported employment.ResultsOlder age and diagnosis of schizophrenia were found to be independent predictors of unemployment in the previous year. Other factors of unemployment such as ethnicity and educational level were not associated with obtaining employment.Clinical implicationsOlder people and those with a diagnosis of schizophrenia may need additional targeted help in obtaining employment if they are to be helped to meet their vocational aims. Further research is needed to determine how this can be done most effectively.

Abstract
OBJECTIVE The aim of this study was to explore how physical activity (PA) and energy intake (EI) changes were related to weight loss and regain following "The Biggest Loser" competition. METHODS At baseline, week 6 and week 30 of the competition, and 6 years after the competition, body composition was measured via dual-energy x-ray absorptiometry, resting energy expenditure was measured by using indirect calorimetry, and EI and PA were measured by using doubly labeled water. RESULTS Six years after the competition, median weight loss in 14 of "The Biggest Loser" participants was 13%, with those maintaining a greater weight loss (mean ± SE) of 24.9% ± 3.8% having increased PA by 160% ± 23%, compared with a PA increase of 34% ± 25% (P = 0.0033) in the weight regainers who were 1.1% ± 4.0% heavier than the precompetition baseline. EI changes were similar between weight loss maintainers and regainers (-8.7% ± 5.6% vs. -7.4% ± 2.7%, respectively; P = 0.83). Weight regain was inversely associated with absolute changes in PA (r = -0.82; P = 0.0003) but not with changes in EI (r = -0.15; P = 0.61). EI and PA changes explained 93% of the individual weight loss variability at 6 years. CONCLUSIONS Consistent with previous reports, large and persistent increases in PA may be required for long-term maintenance of lost weight.

Abstract
The safety of using Gd in MRI contrast agents has recently been questioned, due to recent evidence of the retention of Gd in individuals with healthy renal function. Bone has proven to be a storage site for Gd, as unusually high concentrations have been measured in femoral heads of patients undergoing hip replacement surgery, as well as in autopsy samples. All previous measurements of Gd in bone have been invasive and required the bone to be removed from the body. X-ray fluorescence (XRF) offers a non-invasive and non-destructive method for carrying out in vivo measurements of Gd in humans. An updated XRF system provides improved detection limits in a short measurement time of 30-min. A new four-detector system and higher activity Cd-109 excitation source of 5GBq results in minimum detection limits (MDLs) of 1.64-1.72μgGd/g plaster for an average overlaying tissue thickness of the tibia. These levels are well within the range of previous in vitro Gd measurements. Additional validation through comparison with ICP-MS measurements has confirmed the ability of the XRF system for detecting Gd further, proving it is a feasible system to carry out human measurements.

Abstract
Mean pulmonary arterial pressure and pulmonary vascular resistance (PVR) remain the most common haemodynamic measures to evaluate the severity and prognosis of pulmonary hypertension. However, PVR only captures the non-oscillatory component of the right ventricular hydraulic load and neglects the dynamic compliance of the pulmonary arteries and the contribution of wave transmission. Wave intensity analysis offers an alternative way to assess the pulmonary vasculature in health and disease. Wave speed is a measure of arterial stiffness, and the magnitude and timing of wave reflection provide information on the degree of impedance mismatch between the proximal and distal circulation. Studies in the pulmonary artery have demonstrated distinct differences in arterial wave propagation between individuals with and without pulmonary vascular disease. Notably, greater wave speed and greater wave reflection are observed in patients with pulmonary hypertension and in animal models exposed to hypoxia. Studying wave propagation makes a valuable contribution to the assessment of the arterial system in pulmonary hypertension, and here, we briefly review the current state of knowledge of the methods used to evaluate arterial waves in the pulmonary artery.

Abstract
AIMS For patients with high-risk, locally bulky prostate cancer, an intra-prostatic boost to tumour volumes (dose-painting) offers a risk-adapted dose escalation. We evaluated the feasibility of hypofractionated dose-painting radiotherapy and the associated toxicity. The possibility to streamline a radiobiologically optimised planning protocol was also investigated. MATERIALS AND METHODS Twenty-eight patients were treated using a dose-painting approach; boost volumes were identified with functional magnetic resonance imaging scans. The prostate dose outside the boost volume was 60 Gy in 20 fractions, and the maximum integrated boost dose was set to 68 Gy, provided that the dose constraints to the organs at risk could be fulfilled. Rotational intensity-modulated radiotherapy was used with daily image guidance and fiducial markers. RESULTS The boost dose was escalated to 68 Gy for 25 patients (median dose 69 Gy, range 68-70 Gy); for three patients the boost dose was 67 Gy, due to the proximity of the urethra and/or the rectum. The mean normal tissue complication probability for rectal bleeding was 4.7% (range 3.4-5.8%) and was 3.5% for faecal incontinence (range 2.3-5.0%). At a median follow-up of 38 months (range 32-45) there was no grade 3 toxicity. Two patients developed grade 2 genitourinary toxicity (7.1%) and none developed grade 2 gastrointestinal toxicity. The mean prostate-specific antigen (PSA) for 23 patients who had stopped the adjuvant hormone therapy with a normal testosterone was 0.27 ng/ml (0.02-0.72) at follow-up; two patients have suppressed PSA and testosterone after stopping 3 year adjuvant hormone and three patients have relapsed (one pelvic node, two PSA only) at 36, 12 and 42 months, respectively. CONCLUSIONS A hypofractionated radiotherapy schedule, 60 Gy in 20 fractions with intra-prostatic boost dose of 68 Gy, can be achieved without exceeding dose constraints for organs at risk. Hypofractionated dose-painting escalated radiotherapy has an acceptable safety profile. The same planning protocol was used in a phase II single-arm trial (BIOPROP20: ClinicalTrials.gov identifier NCT02125175) and will further be used in a large phase III randomised trial (PIVOTALboost): patients will be randomised standard radiotherapy (60 Gy in 20 fractions) with or without lymph node radiotherapy versus dose-painting radiotherapy with or without lymph node radiotherapy; the trial will be opened for recruitment in summer 2017.

Abstract
OBJECTIVE To measure long-term changes in resting metabolic rate (RMR) and body composition in participants of "The Biggest Loser" competition. METHODS Body composition was measured by dual energy X-ray absorptiometry, and RMR was determined by indirect calorimetry at baseline, at the end of the 30-week competition and 6 years later. Metabolic adaptation was defined as the residual RMR after adjusting for changes in body composition and age. RESULTS Of the 16 "Biggest Loser" competitors originally investigated, 14 participated in this follow-up study. Weight loss at the end of the competition was (mean ± SD) 58.3 ± 24.9 kg (P < 0.0001), and RMR decreased by 610 ± 483 kcal/day (P = 0.0004). After 6 years, 41.0 ± 31.3 kg of the lost weight was regained (P = 0.0002), while RMR was 704 ± 427 kcal/day below baseline (P < 0.0001) and metabolic adaptation was -499 ± 207 kcal/day (P < 0.0001). Weight regain was not significantly correlated with metabolic adaptation at the competition's end (r = -0.1, P = 0.75), but those subjects maintaining greater weight loss at 6 years also experienced greater concurrent metabolic slowing (r = 0.59, P = 0.025). CONCLUSIONS Metabolic adaptation persists over time and is likely a proportional, but incomplete, response to contemporaneous efforts to reduce body weight.

Abstract
Dietary carbohydrate restriction has been purported to cause endocrine adaptations that promote body fat loss more than dietary fat restriction. We selectively restricted dietary carbohydrate versus fat for 6 days following a 5-day baseline diet in 19 adults with obesity confined to a metabolic ward where they exercised daily. Subjects received both isocaloric diets in random order during each of two inpatient stays. Body fat loss was calculated as the difference between daily fat intake and net fat oxidation measured while residing in a metabolic chamber. Whereas carbohydrate restriction led to sustained increases in fat oxidation and loss of 53 ± 6 g/day of body fat, fat oxidation was unchanged by fat restriction, leading to 89 ± 6 g/day of fat loss, and was significantly greater than carbohydrate restriction (p = 0.002). Mathematical model simulations agreed with these data, but predicted that the body acts to minimize body fat differences with prolonged isocaloric diets varying in carbohydrate and fat.

Abstract
Constraints involving the delivery method of glial cell line-derived neurotrophic factor (GDNF) have hampered its efficacy as a neuroprotectant in Parkinson's disease. Ex vivo gene therapy, in which suitable cells, such as bone marrow-derived mesenchymal stem cells (MSCs), are genetically engineered to overexpress GDNF (GDNF-MSCs) prior to transplantation may be more beneficial than direct brain infusion of the neurotrophin. Previously, GDNF-MSCs have been assessed in the commonly employed 6-hydroxydopamine neurotoxic model of Parkinson's disease. In this study however, we used an emerging inflammatory model of Parkinson's disease (the lipopolysaccharide (LPS) model) to assess the ability of transplanted GDNF-MSCs to protect against LPS-induced neuroinflammation, neurodegeneration and behavioral impairment. Thirty male Sprague-Dawley rats were used in this experiment. Rats were performance matched based on baseline motor function tests into three groups (LPS lesion only, LPS lesion+GFP-MSCs, LPS lesion+GDNF-MSCs; n=10/group). Both cell groups received a unilateral intra-striatal transplant of either 200,000 GDNF-MSCs or 200,000 GFP-MSCs (as a control). One day post-transplantation, all rats received a unilateral intra-nigral infusion of LPS (10 μg in 2 μl sterile saline). Rats were sacrificed by transcardial perfusion-fixation and their brains were used for post mortem quantitative immunohistochemistry. Injection of LPS into the substantia nigra induced a pronounced local inflammatory response which resulted in 20% loss of nigrostriatal dopaminergic neurons and impaired contralateral motor function. Following transplantation of GDNF-MSCs to the striatum, dense areas of TH-positive staining directly proximal to the transplant site were observed. Most importantly, this effect was observed only in the GDNF-MSC transplanted group and not the GFP-MSC transplanted group demonstrating protection and/or sprouting of the dopaminergic terminals induced by the secreted GDNF. This study is the first to highlight the neurotrophic capability of GDNF in the inflammation-driven LPS model and, while future studies will endeavor to improve this approach by increasing cell survival, this work highlights the potential of GDNF delivery by ex vivo gene therapy using MSCs.

Abstract
BACKGROUND MicroRNAs (miRNAs) are noncoding RNA molecules that play important roles in the pathogenesis of various kidney diseases. We investigated whether patients with minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS) have distinct circulating and urinary miRNA expression profiles that could lead to potential development of noninvasive biomarkers of the disease. MATERIALS AND METHODS Exosome miRNAs were extracted from plasma and urine samples of patients with primary FSGS (n = 16) or MCD (n = 5) and healthy controls (n = 5). Differences in miRNA abundance were examined using Affymetrix GeneChip miRNA 3.0 arrays. QRT-PCR was used to validate the findings from the array. RESULTS Comparison analysis of FSGS versus MCD revealed 126 and 155 differentially expressed miRNAs in plasma and in urine, respectively. Only 38 of these miRNAs were previously cited, whereas the remaining miRNAs have not been described. Comparison analysis showed that a significant number of miRNAs were downregulated in both plasma and urine samples of patients with FSGS compared to those with MCD. Plasma levels of miR-30b, miR-30c, miR-34b, miR-34c and miR-342 and urine levels of mir-1225-5p were upregulated in patients with MCD compared to patients with FSGS and controls (P < 0.001). Urinary levels of mir-1915 and miR-663 were downregulated in patients with FSGS compared to MCD and controls (P < 0.001), whereas the urinary levels of miR-155 were upregulated in patients with FSGS when compared to patients with MCD and controls (P < 0.005). CONCLUSIONS Patients with FSGS and MCD have a unique circulating and urinary miRNA profile. The diagnostic and prognostic potential of miRNAs in FSGS and MCD warrants further studies.

Abstract
BACKGROUND Women's crisis houses have been developed in the UK as a less stigmatising and less institutional alternative to traditional psychiatric wards. AIMS To examine the effectiveness and cost-effectiveness of women's crisis houses by first examining the feasibility of a pilot patient-preference randomised controlled trial (PP-RCT) design (ISRCTN20804014). METHOD We used a PP-RCT study design to investigate women presenting in crisis needing informal admission. The four study arms were the patient preference arms of women's crisis house or hospital admission, and randomised arms of women's crisis house or hospital admission. RESULTS Forty-one women entered the randomised arms of the trial (crisis house n = 19, wards n = 22) and 61 entered the patient-preference arms (crisis house n = 37, ward n = 24). There was no significant difference in outcomes (symptoms, functioning, perceived coercion, stigma, unmet needs or quality of life) or costs for any of the groups (randomised or preference arms), but women who obtained their preferred intervention were more satisfied with treatment. CONCLUSIONS Although the sample sizes were too small to allow definite conclusions, the results suggest that when services are able to provide interventions preferred by patients, those patients are more likely to be satisfied with treatment. This pilot study provides some evidence that women's crisis houses are as effective as traditional psychiatric wards, and may be more cost-effective.

Abstract
We have developed a novel glass-ionomer cement (GIC) system composed of photo-curable star-shaped poly(acrylic acid-co-itaconic acid)s. These polyacids were synthesized via a chain-transfer radical polymerization using a newly synthesized multi-arm chain-transfer agent. The star-shaped polyacids showed significantly lower viscosities in water as compared to the linear polyacids. Due to the lower viscosities, the molecular weight (MW) of the polyacids can be significantly increased for enhancing the mechanical strengths while keeping the ease of mixing and handling. The effects of MW, GM-tethering ratio, P/L ratio, and aging on the compressive properties of the experimental cements were significant. The light-cured experimental cements showed significantly improved mechanical strengths i.e. 49% in yield strength, 41% in modulus, 25% in CS, 20% in DTS, and 36% in FS, higher than commercial Fuji II LC. After aging in water for 1 month, the compressive strength of the novel light-cured experimental cement reached 343 MPa, which was 34% and 42% higher than Fuji II and Fuji II LC, respectively. This one-month aged experimental cement was also 23% higher than itself after one day aging, indicating that aging in water can significantly enhance salt-bridge formation for this novel star-shaped polyacid-comprised GIC.

Abstract
BACKGROUND/AIMS Microalbuminuria is a marker for early kidney disease and cardiovascular risk. The purposes of this study were to determine the prevalence of microalbuminuria in an HIV-infected clinic population, to test the predictive value of a single urine albumin/creatinine ratio (ACR) to identify persistent microalbuminuria and to examine covariates of microalbuminuria. METHODS We conducted a prospective cohort study of HIV-infected subjects (n = 182) without proteinuria (urine protein/creatinine ratio ≥0.5 g/g), elevated serum creatinine, diabetes, or chronic inflammatory conditions. Subjects completed three research visits within 9 months. Microalbuminuria was defined as the geometric mean ACR of 25-355 mg/g for females and 17-250 mg/g for males. RESULTS The prevalence of microalbuminuria was 14%. The negative predictive value of a single urine ACR determination was 98%, whereas the positive predictive value was only 74%. Microalbuminuria was similar among Black (15%) and non-Black (14%) subjects (p = 0.8). Subjects with microalbuminuria were more likely to have hypertension (p = 0.02) and metabolic syndrome (p = 0.03). While duration of HIV infection and the level of HIV viremia were similar between groups, those with microalbuminuria were more likely to have a CD4 count <200 cells/μl (p = 0.0003). In a multivariate logistic regression analysis, the only significant independent predictors of microalbuminuria were low CD4 count (p = 0.018) and current ritonavir exposure (p = 0.04). CONCLUSION The prevalence of microalbuminuria in an HIV-infected clinic population was similar to earlier reports, and was associated with hypertension and impaired immune function. A single normal ACR determination effectively excludes microalbuminuria, whereas an elevated ACR requires confirmation.
