Introduction Co-production is a collaborative approach to service user involvement in which users and researchers share power and responsibility in the research process. Although previous reviews ...have investigated co-production in mental health research, these do not typically focus on psychosis or severe mental health conditions. Meanwhile, people with psychosis may be under-represented in co-production efforts. This scoping review aims to explore the peer-reviewed literature to better understand the processes and terminology employed, as well as the barriers, facilitators, and outcomes of co-production in psychosis research. Methods Three databases were searched (MEDLINE, EMBASE, PsycINFO) using terms and headings related to psychosis and co-production. All titles, abstracts and full texts were independently double-screened. Disagreements were resolved by consensus. Original research articles reporting on processes and methods of co-production involving adults with psychosis as well as barriers, facilitators, and/or outcomes of co-production were included. Data was extracted using a standardised template and synthesised narratively. Joanna Briggs Institute and the AGREE Reporting Checklist were used for quality assessment. Results The search returned 1243 references. Fifteen studies were included: five qualitative, two cross-sectional, and eight descriptive studies. Most studies took place in the UK, and all reported user involvement in the research process; however, the amount and methods of involvement varied greatly. Although all studies were required to satisfy INVOLVE (2018) principles of co-production to be included, seven were missing several of the key features of co-production and often used different terms to describe their collaborative approaches. Commonly reported outcomes included improvements in mutual engagement as well as depth of understanding and exploration. Key barriers were power differentials between researchers and service users and stigma. Key facilitators were stakeholder buy-in and effective communication. Conclusions The methodology, terminology and quality of the studies varied considerably; meanwhile, over-representation of UK studies suggests there may be even more heterogeneity in the global literature not captured by our review. This study makes recommendations for encouraging co-production and improving the reporting of co-produced research, while also identifying several limitations that could be improved upon for a more comprehensive review of the literature.

Vitamin D deficiency has been related with metabolic alterations in polycystic ovary syndrome (PCOS). As well, hyperactivation of adrenal axis can be programmed early in life and could be related ...later with PCOS development. Our aim was to establish the relationship between vitamin D and adrenal parameters with metabolic alterations and inflammation markers in PCOS. In 73 patients and 33 controls, 25-hydroxyvitamin D (25-OH-D), total and bioavailable testosterone (TT and bioT), androstenedione (A4), SHBG, cortisol, insulin, and C-reactive protein (hs-CRP) were determined; HOMA and lipid accumulation product (LAP) index were calculated. All parameters were higher in patients than in controls, except for SHBG and 25-OH-D which were lower. Binary regression analysis showed that differences in TT, bioT, A4, insulin and HOMA were independent of body mass index and waist circumference but SHBG, hs-CRP, LAP and 25-OH-D were related to body weight and fat distribution. Binary logistic regression analysis showed that cortisol and 25-OH-D could be associated to PCOS development. Correlations found between LAP and insulin, HOMA and hs-CRP confirm it is a good indicator of metabolic complications. Vitamin D and cortisol association to PCOS development justifies future research to understand the role of vitamin D in PCOS and analyze patient's perinatal history and its possible relationship with hyperactivation of adrenal axis in adult life.
Entecavir (ETV) is a guanosine nucleoside analogue with potent antiviral efficacy in woodchucks chronically infected with woodchuck hepatitis virus. To explore the consequences of prolonged virus ...suppression, woodchucks received ETV orally for 8 weeks and then weekly for 12 months. Of the 6 animals withdrawn from therapy and monitored for an additional 28 months, 3 had a sustained antiviral response and had no evidence of hepatocellular carcinoma (HCC). Of the 6 animals that continued on a weekly ETV regimen for an additional 22 months, 4 exhibited serum viral DNA levels near the lower limit of detection for >2 years and had no evidence of HCC. Viral antigens and covalently closed circular DNA levels in liver samples were significantly reduced in all animals. ETV was well tolerated, and there was no evidence of resistant variants. On the basis of historical data, long-term ETV treatment appeared to significantly prolong the life of treated animals and delay the emergence of HCC
Abstract
A 90–year–old woman is brought to the closest emergency room after being found in a confusional state of mind, with lateral–sided sight deviation with normal cardiovascular findings. Her ...past medical history is characterized by the presence of systemic hypertension, moderate–to–severe chronic disease. The 12–lead electrocardiogram showed sinus rhythm and aspecific anomalies of the left ventricular repolarization. Lab tests showed normal white blood cells count with increased creatinine levels and quite normal flogosis indices. An initial transthoracic echocardiogram (TTE) showed mild left ventricular concentric hypertrophy with preserved systolic function, but also revealed the presence of a moving posterior mitral leaflet mass, determining mild mitral regurgitation. A head CT scan was performed, showing a right temporo–insular ischemic ipodensity. Considering the echocardiographic and neuronal findings, a transesophageal echocardiogram (TEE) was indicated to look for and better describe the suspicious mass, after beginning an antibiotic therapy in an empiric regimen. TEE revelead a multi–lobular mass characterized by inhomogeneous echogenicity, leaning on the annulus and the atrial side of the posterior mitral leaflet that was fissurated, leading to mild mitral regurgitation. The left appendage showed normal emptying velocity and absence of thrombi. It was not easy to describe this mass morphology and dimensions, but in some projections, it reminded us of a reindeer with various antlers. This case could resemble a classic mitral valve endocarditis, evolved into valve fissuration and arterial embolization leading to ischemic stroke, but the unusual fact is that the laboratory tests showed no white blood cells alteration during the whole hospitalization, with a really minimal CRP change and always negative procalcitonin. That is why we came into the idea that such a mass could also not represent a classical endocarditis. Considering that the echocardiographic characteristics of a thrombus were not encountered, the mass may be a tumor. The most frequent tumors involving the heart valves are papillary fibroelastomas. Considering the absence of clinic endocarditis, some hints led to consider this differential diagnosis: fibroelastomas mostly occur during older ages, they frequently have a mitral or aortic location and they can embolize, differently from vegetations, they are located mostly on the annulus and the basal posterior mitral leaflet.

Abstract A 64–years old male patient was admitted in the Emergency Department with signs of heart failure in a setting of dilated hypokinetic cardiomyopathy with severe depression of left ventricular ...ejection fraction and no severe coronary artery disease. In the previous medical history: systemic arterial hypertension, obesity, dysthyroidism due to amiodarone, history of atrial fibrillation treated by transcatheter ablation in the left atrium with pulmonary veins isolation (PVI) and the creation of an anterior line in 2010. The ECG documented an atrial flutter rhythm 2:1 probably typical (Fig. 1). An indication was therefore made for hospitalization in Cardiology. After the restoration of a good hemodynamic state, given the persistence of the atrial tachyarrhythmia, an indication for transcatheter ablation was formulated. The electrophysiological study highlighted an activation sequence suggestive of typical common flutter (cranial–caudal right atrial activation; proximal–distal left atrial activation). We then proceeded to ablate the cavo–tricuspid isthmus without interrupting the arrhythmia. Therefore, left and right atrial electroanatomical mapping was performed which confirmed the right isthmic block and documented the left origin of the flutter, showing conduction gaps in the ostia of the pulmonary veins and in the previous anterior ablation line between the mitral annulus and the right superior pulmonary vein (RSPV) (Fig 2,3). Ablation of these gaps effectively stopped the arrhythmia. At the end of the procedure, after stimulation via atrial bursts of up to 200 msec there was no induction of arrhythmias. One month after the procedure, there was an improvement in the contractile function of the left ventricle. Discussion: This clinical case offers us an example of how the analysis of the surface ECG alone is not sufficient to adequately describe the complexity of the arrhythmic substrate characterizing an arrhythmia such as atrial flutter or atrial fibrillation. The electrophysiological study through electroanatomical reconstruction of endocavitary activation proves indispensable for the correct identification and consequent treatment of these complex arrhythmias, with clear clinical benefits for the patient.
Abstract
Background
Contrast-induced acute kidney injury (CI-AKI) after coronary angiography and percutaneous interventions (PCI) impacts on hospitalization duration and mortality. Pre-procedural ...hydration is the sole strategy currently recommended for preventing CI-AKI. The role of sodium bicarbonate (SB) although attractive, since urine alkalinization suppresses the production of reactive oxygen species, is still controversial, and the optimal dosing to attain adequate urine alkalinization is still undefined.
Purpose
The PrevenTion of contrast-inducEd nephropathy with urine alkalinization (TEATE) study was a prospective 3-center 3-arm single-blind randomized controlled trial testing the hypothesis that adequate urine alkalinization is associated with CI-AKI prevention. Secondary endpoints were the efficacy of SB vs saline in achieving adequate urine alkalinization and reducing the incidence of CI-AKI compared with saline.
Methods
Patients candidate to coronary angiography and/or PCI with moderate-to-severe chronic kidney disease eGFR of 15 to 60 mL/min/1.73 m2, by the Modification of Diet in Renal Disease Study equation (MDRD) were randomly assigned to saline hydration (control), oral SB or i.v. SB. The study protocol was registered. We evaluated urinary pH at the time of hospitalization, immediately before coronary angiography and 24–48 hours after angiography. According to urine pH immediately before the procedure, patients were divided in two groups above or below a pH cut-off of 6.
Results
We enrolled a total of 241 patients: 81 were randomly assigned to the control group, 82 to i.v. SB and 78 to oral SB. Patients achieving a urinary pH >6 before angiography had a lower incidence of CI-AKI (46%) than patients with urinary pH ≤6 (54%) OR=0.48 (95% CI 0.25–0.9) p=0.023. The number of patients with urine pH >6 was higher in both the i.v. (71%) and the oral SB (65%) groups compared to the hydration-only group (44%, p=0.004). We found however no difference in the incidence of CI-AKI in the 3 treatment arms (20% in hydration alone, 21% in oral SB group and 22% in iv SB group) (p=0.94). Subgroup analyses according to basal urine pH and eGFR ranges failed to identify statistically significant differences in the development of CI-AKI according to treatment allocation.
Conclusions
Urinary pH before the administration of contrast medium is an inverse correlate of CI-AKI incidence, and SB is superior to hydration alone in achieving urinary alkalinization. Since, however, SB did not reduce the incidence of CI-AKI, we conclude that urinary pH is a marker and not a mediator of CI-AKI.
