A sub-analysis of the time and subject requirements associated with each type of PE did not provide an explanation for the differences observed. In conclusion, this exploratory analysis indicates differences in study size, duration and type of PE used by small/mid-sized and large companies. For some types of endpoints, differences in length and study size were found. However, it wasn't possible to attribute these differences between sponsors solely to the choice of PE, pointing out to the complexity of running clinical trials.We conducted formative research using in-depth interviews to identify preferences for and anticipated responses to receiving thank you notes and lay summaries of aggregate results among caregivers and adolescent participants of pragmatic pediatric studies conducted by the National Institute of Health-sponsored Pediatric Trials Network. We analyzed the data using qualitative thematic analysis. Nearly all participants said receiving a thank you note would make them feel valued, appreciated, and proud because they contributed to science. Similarly, nearly all participants said that receiving a lay summary of research results would make them aware of their role in improving the lives of children, feel like they are an active partner in research, and believe that researchers want to keep them informed. Participants also said that receiving a thank you note or lay summary may motivate them to participate in future research. Providing thank you notes as part of study participation should become a standard clinical trial practice, similar to the practice of providing lay summaries.

The undergraduate teaching of urology is not uniform in the various European medical schools and even absent in some of them, despite the widespread adoption of the Bologna process, which advocates a standardization and harmonization of medical education. Our aim was to evaluate the perception of junior doctors about the undergraduate teaching of Urology and the exposure to the specialty of Urology in undergraduate education in Portuguese medical schools.

A questionnaire was emailed to all physicians who first enrolled in the Board of Portuguese Doctors in 2017 and 2018. The questionnaire consisted of several questions about specialty exposure, pathology, and basic urological procedures. A database for statistical analysis was created.

One hundred and eighty-six answers were considered valid. Although almost all participant physicians attribute considerable importance to Urology specialty, most find their exposure to urological pathology and basic urological procedures to be inappropriate in medical school. Urinary lithiasis and lower urinary tract symptoms are the subjects on which doctors feel most prepared after graduating. Interestingly, 63.4% of doctors consider that the education they had in college was preponderant in choosing their specialty.

The teaching of Urology in Portuguese Medical Schools is considered by junior doctors as inadequate, not reflecting the importance of this specialty in the clinical practice. These results are like those found in other countries. A reflection and consequent change of the teaching paradigm is necessary, namely at the practical teaching level.

In the wake of the COVID-19 pandemic and the accompanied urgency for a lasting treatment, drug repurposing has come in handy to stem the debilitating effects of the disease. Among other therapeutic options currently in clinical trials, chloroquine (CQ) and the hydroxylated analogue, hydroxychloroquine (HCQ) have been frontline therapeutic options in most formal and informal clinical settings with varying degrees of efficacy against this life-threatening disease. Their status in randomized clinical trials is related to the biochemical and pharmacological profiles as validated by in vitro, in vivo and case studies. With the aim to bear a balance for their use in the long run, this review not only synopsizes findings from recent studies on the degrees of efficacy and roles of CQ/HCQ as potential anti-COVID-19 agents but also highlights our perspectives for their consideration in rational drug repositioning and use.

Health-related quality of life is different among different transplant cohorts with respect to different variables which predict mortality and graft survival. The aim of this study was to identify the effects of clinical factors on the health-related quality of life in postrenal transplant patients.

This census study was conducted at the Institute of Kidney Diseases Peshawar, Pakistan. Data were collected on a questionnaire " Kidney Diseases Quality of Life-Short Form-1.3 Urdu version" and were analyzed in the 3 main domains, for example, physical component summary (PCS), mental component summary, and kidney disease component summary using SPSS version 21. Mean scores for patients with diabetes mellitus (DM), hypertension, levels of hemoglobin, and serum creatinine were compared by unpaired

-test.

A total of 277 men (87.9%) and 38 (12.1%) women participated in the study. Mean age was 37.26 (±10.14) years (range 18-65 years). Hypertension was reported in 72.2% and DM in 10.8%. Hemoglobin was <12.5g% in 26.0% patients. Patients with DM had significant lower PCS (

 = .001) and mental component summary (MCS;

 = .001) scores. Patients with hypertension had significant lower MCS score (

 = .01). Patients with hemoglobin <12.5g% had significantly lower PCS (

 = .001) score than those with hemoglobin >12.5 g%. The PCS score in patients with serum creatinine level >2 mg% was significantly lower (

 = .02) than those with serum creatinine <2 mg%.

Lower graft function and DM were associated with lower PCS and MCS scores. Hypertension was associated with lower MCS score and anemia with lower PCS score.

Lower graft function and DM were associated with lower PCS and MCS scores. Hypertension was associated with lower MCS score and anemia with lower PCS score.[This corrects the article DOI 10.1253/circrep.CR-20-0099.].Background Risk stratification of normal-flow, low-gradient (NFLG) severe aortic stenosis (SAS) with preserved left ventricular (LV) ejection fraction (EF) remains unclear. learn more Methods and Results Of 289 consecutive patients diagnosed with SAS by aortic valve area 95 mg/m2 for males and females, respectively; HR 3.257; 95% CI 1.172-9.050; P=0.024), and tricuspid regurgitation (TR) velocity (HR 2.761; 95% CI 1.246-6.118; P=0.012). Conclusions The presence of symptoms, LV hypertrophy, and high TR velocity could be reliable prognostic indicators and may require watchful waiting for timely AVR in patients with NFLG-SAS.Background Wild-type transthyretin cardiac amyloidosis (ATTRwt-CA) is a life-threatening progressive disease. Recent studies have shown that the detection of transthyretin (TTR) amyloid in tenosynovial tissue may play an important role in the diagnosis of cardiac amyloidosis. The aim of this study was to determine the prevalence of TTR amyloid deposits in surgical tissue of patients undergoing carpal tunnel surgery and to clarify the clinical significance of concomitant cardiac examination with 99 mTc-labeled pyrophosphate (99 mTc-PYP) scintigraphy in those patients with TTR deposition. Methods and Results We evaluated 79 consecutive patients undergoing carpal tunnel release surgery and biopsy of tenosynovial tissue. The mean (±SD) age of the patients at surgery was 71.6±12.5 years (range 30-95 years); 32 patients (41%) were male. TTR amyloid deposition in tenosynovial tissue was observed in 27 patients (34%). Sixteen of those 27 patients underwent 99 mTc-PYP scintigraphy. Of those 16 patients, 3 (19%) had Grade 2 uptake on 99 mTc-PYP scintigraphy. None of the 3 patients with a diagnosis of ATTRwt-CA had apparent cardiac symptoms and left ventricular wall thickness >13 mm. Conclusions Concomitant cardiac examination with 99 mTc-PYP scintigraphy in patients who had TTR amyloid deposition in tenosynovial tissue resulted in the identification of 19% of patients with a diagnosis of ATTRwt-CA. This diagnostic approach seems to be useful for the early diagnosis of the disease.Background The effects of mineralocorticoid receptor antagonists, including the newly introduced esaxerenone, on renal function remain uncertain. Methods and Results This retrospective study was performed on patients who received esaxerenone for resistant hypertension between November 2019 and June 2020. Trends in the estimated glomerular filtration rate (eGFR) were compared between the 6-month period before esaxerenone treatment (pre-treatment period) and the 6-month treatment period on esaxerenone. Twenty-six patients (15 men), with a median age of 70 years (interquartile range [IQR] 51-73 years) and a median systolic blood pressure of 146 mmHg (IQR 139-156 mmHg), were included in the study and completed 6 months of esaxerenone therapy without any adverse events. eGFR decreased significantly during the pre-treatment period (from 66.6 to 59.5 mL/min/1.73 m2; P=0.003), whereas eGFR was unchanged during the treatment period (from 59.5 to 61.8 mL/min/1.73 m2; P=0.15). The median change in eGFR differed significantly between the treatment and pre-treatment periods (3.8 [IQR -4.2, 6.8] vs. -6.1 [IQR -11.1, 1.8] mL/min/1.73 m2, respectively; P=0.008). Conclusions Esaxerenone may have renoprotective effects when administered to treat hypertension. Further studies are needed to understand which patient populations may see greater renoprotective benefits with esaxerenone.Background The mechanism underlying serum creatinine (SCr) fluctuations in heart failure (HF) patients remains unclear. This study examined mediators of SCr fluctuations under diuretic treatment in HF patients. Methods and Results Data from 26 HF patients were analyzed. Clinical tests included measurement of peripheral blood, blood urea nitrogen, SCr, serum and urinary electrolytes, B-type natriuretic peptide (BNP), and plasma neurohormones. Among the 26 patients recovering from worsening HF, changes in SCr were negatively correlated with changes in serum Cl, and positively correlated with changes in plasma arginine vasopressin (AVP). According to the median change in SCr, patients were divided into high (range 0.16-0.79 mg/dL; n=13) and low (range -0.35 to 0.14 mg/dL; n=13) change groups. Plasma AVP concentrations after treatment decreased in the low SCr change group and increased in the high SCr change group (-1.28±2.8 vs. 2.14±4.4 pg/mL, respectively; P=0.027). In both groups, there was no change in plasma volume, plasma BNP and norepinephrine concentrations decreased, and plasma renin activity increased after treatment. Multivariate logistic regression analysis showed a tendency towards an independent association between an increase in SCr and an increase or no change in the plasma AVP after decongestion (odds ratio 4.44; 95% confidence interval 0.81-24.3; P=0.086). Conclusions Plasma AVP appears to be a physiologically important mediator of SCr fluctuations under decongestion treatment in HF patients.
