Abstract
BackgroundAbout half of patients with giant cell arteritis (GCA) relapse while tapering glucocorticoid therapy1. A previous observational study reported that blockade of the renin-angiotensin system, with angiotensin II receptor blockers (ARBs), was associated with lower relapse risk2.ObjectivesTo determine whether angiotensin blockade, with angiotensin converting enzyme inhibitor (ACEi) or ARB, is associated with differential relapse risk in GCA.MethodsGCA patients from a tertiary centre diagnosed 2012–2020 with two years follow-up were identified from UK GCA Consortium. All provided written informed consent. Retrospective review of medical records included demographics, comorbidities, drug history, inflammatory markers and relapses. Relapse was defined as return of symptoms, raised inflammatory markers, or active vasculitis on imaging confirmed by the treating clinician. Relapse-free survival was analysed using Kaplan Meier (KM) curves and Cox proportional hazards.Results111 patients were included (Table 1: demographic data), all were initially treated with 40–60mg Prednisolone. 42% received further immunosuppressants due to relapse or disease severity. 50% patients relapsed in two years, presenting with cranial symptoms (72%), PMR-like symptoms (30%) and/or raised inflammatory markers (48%). There was no association between relapse and age, gender, comorbid HTN/IHD or pre-steroid inflammatory markers and relapse. Rate of steroid taper can affect relapse. EULAR recommend 15–20mg of steroid by three months3. 9 patients relapsed within that time and were excluded, there was no difference in steriod dose at three months between the two groups. KM analysis showed ACEi did not significantly affect time to relapse compared to no angiotensin blockade (HR 0.57, 95% CI 0.28 – 1.18, unadjusted p-value=0.128), and neither did an ARB (HR 0.78, 95% CI 0.31 – 1.98, unadjusted p-value=0.605).Table 1.demographic data at baseline.Relapse (n = 56)No Relapse (n = 55)Patient FactorsAge median (IQR)70 (65-74)73 (67-78)Male Sex n (%)16 (29)20 (36.36)Medications n (%)ACEi9 (15)16 (29)ARB7 (12)7 (13)Comorbidities n (%)CKD4 (7)9 (16)IHD6 (11)5 (9)Prediabetes11 (20)10 (18)DM1 (2)5 (9)HTN22 (40)23 (42)Current Smoker6 (10)2 (4)GCA Factors median (IQR)CRP pre-treatment69 (32 – 131)64 (23 -115)ESR pre-treatment50 (37 -95)4 (22 -72)Steroid dose at 3 months19 (15 -20)15 (10-20)Figure 1.Unadjusted KM survival curve showing probability of relapse in patients 1) taking ACEi, 2) taking ARB, 3) taking neither ACEi or ARB, 4) with no comorbid HTN or IHD at diagnosis, and 5) experienced comorbid HTN/IHD. There was no significant difference in relapse free survival in patients on an ACEi compared to those taking neither ACEi or ARB.ConclusionIn the two years following GCA diagnosis 50% relapsed. There was no significant difference in the rate of relapse in patients taking an ACEi or ARB. The main limitation, in this retrospective, observational study was the inability to exclude a reluctance of clinicians to diagnose GCA relapse in the presence of cardiovascular comorbidity. A randomised controlled trial would be needed to determine whether starting an ACEi could reduce relapse risk in patients with new-onset GCA.References[1]Mainbourg, S. et al.

Abstract
Background Central venous access devices (CVAD) are an essential part of safe practices in critical care, which enable effective venous access and help in avoiding repeated venipuncture. Discard method is widely practiced for blood sampling. A single occasion of blood sampling may cause minimal blood loss; however, the cumulative volume sequential sampling may become clinically significant. The study aims to reduce diagnostic blood loss, ensuring that the subsequent blood sample is not diluted or contaminated by residual intraluminal fluid. Patients and Methods Within-subjects comparative design was adopted for 64 adult patients in the medical intensive care unit of a tertiary hospital. Two blood samples, using 3 mL and 5 mL discarded volume methods, were collected from each patient. Six serum parameters were measured on each of the paired samples and compared. Statistical Analysis Used Paired t -test and Wilcoxon signed rank test were used for comparing the two methods. Bland-Altman plot analysis and intraclass correlation were used for clinically meaningful analysis. Results When tested for fixed bias, there is no statistically significant difference between the methods. Potassium and creatinine levels showed significant proportional bias. The agreement limits of sodium, potassium, creatinine, and direct bilirubin were outside the clinically accepted interval, but the proportion of samples outside these intervals was less than 10%. All serum parameters showed excellent reliability, except for sodium which demonstrated good reliability. Conclusions The practice of discarding 3 mL of blood for discard method is suggested, instead of the standard 5 mL to reduce iatrogenic blood loss. Thus, nurses in critical care are uniquely positioned to limit the diagnostic blood loss while obtaining blood samples.

Abstract
Backgound Idiopathic pulmonary arterial hypertension (IPAH) is a rare condition that requires lung transplantation in patients’ refractory to medical therapy. Pulmonary artery aneurysm (PAA) is a documented complication of IPAH however, optimal management and timing of intervention for this rare entity is not well understood. Case report We report a case of a 51-year-old female who underwent heart-lung transplantation for IPAH and giant PAA. The extreme size of the PAA and underlying pathology encountered in this case precluded both lung transplantation and conventional aneurysm repair. Conclusion This case demonstrates that heart-lung transplantation is a good surgical option for IPAH complicated by giant sized PAA and right heart failure.

Abstract
BACKGROUND Hyperprolactinaemia is a troublesome side-effect of treatment with antipsychotics. AIMS This double-blind, placebo-controlled study aimed at examining the effect of adjunctive treatment with 10 mg aripiprazole on prolactin levels and sexual side-effects in patients with schizophrenia symptomatically maintained on risperidone. METHOD Thirty patients taking risperidone were enrolled into the trial (CTRI/2012/11/003114). Aripiprazole was administered at a fixed daily dose of 10 mg/day for 8 weeks. Serum prolactin was measured at baseline and at 8 weeks. Hyperprolactinaemia-related problems, psychopathology and side-effects were evaluated every 2 weeks. RESULTS Prolactin levels decreased by 58% in the aripiprazole group compared with an increase by 22% in the placebo group. Prolactin levels normalised in 46% of patients in the aripiprazole group (number needed to treat, NNT=2). Aripiprazole improved erectile dysfunction in five out of six patients. There were no significant differences in change in psychopathology or side-effects between groups. CONCLUSIONS Adjunctive aripiprazole reduced prolactin levels in those treated with risperidone, with no effect on psychopathology and extrapyramidal symptoms. This is a potential treatment for hyperprolactinaemia observed during treatment with second-generation antipsychotics. DECLARATION OF INTEREST None.

Abstract
The recording of neural ensembles in awake, behaving rats has been an extremely successful experimental paradigm, providing demonstrable scientific advances. Dynamic control of the position of the implanted electrodes is of key importance as mobile electrodes provide a better signal-to-noise ratio and a better cell/electrode yield than nonmobile electrodes. Here we describe the use of low cost, soon to be commercially available dc motors to successfully control the depth of electrodes. The prototype designed is approximately 30mm in diameter and 50mm in length and weighed about 30gms. This paper presents the results of linear displacements of electrodes achievable with this motorized microdrive.

Abstract
BACKGROUND Despite the proven success of national efforts such as the Special Supplementary Food Program for Women, Infants, and Children (WIC) to curb childhood iron deficiency anemia (IDA) in the United States, aggregate programmatic data may not accurately represent the experience of particularly high risk groups, such as the children of adolescent mothers of low socio-economic status. METHODS This study evaluated the prevalence and severity of childhood anemia and associated risk factors, at one urban teen health center serving primarily low-income adolescent mothers and their children. A total of 175 pediatric WIC charts were reviewed to abstract hemoglobin status and other data. Additionally, 81 mothers were interviewed with regard to their nutritional knowledge and feeding practices; these findings were compared with the measured hemoglobin (Hgb) of their children. RESULTS A total of 34.9% of children in the study population were found to be anemic (Hgb </= 11. 2). Low childhood Hgb status was significantly correlated with racial identification, child age, maternal perception of feeding difficulty, and the presence of concurrent pediatric medical illness. Report of extensive nutritional discussion with a physician was correlated with normal Hgb levels. No differences in nutritional knowledge or feeding practices were detected between mothers of children with low iron status. CONCLUSIONS We conclude that the risk of iron deficiency, even among children receiving WIC services, may be underestimated in certain "nutritionally very high risk" populations. Further study of interventions for IDA in children of young, low-income mothers is recommended.

Abstract
This study evaluated the nutritional knowledge and feeding practices (via a verbal questionnaires) of the clients of one semiurban women, infants, and children (WIC) center, which serves exclusively younger women (aged 12-21) and their children, and compared these variables to the hemoglobin levels of their infants and children. No significant benefit from documented WIC education regarding iron was detectable. African American identification was associated with childhood anemia (p = 0.05); the presence of concurrent medical problems approached significance (p = 0.06). Other previously reported risk associations were not found to be significant. Children with low iron ate more meals outside the home per week (2.9 vs. 1.9, p = 0.10). Despite the proven value of the WIC program in reducing childhood iron deficiency, it appears that members of certain very high-risk populations may not experience the full benefit of this nutritional program and may require additional, targeted interventions.
