Background: There is a lack of renal resistive index (RRI)-based data on the effects of COVID-19 in transplant patients. We aimed to investigate the effect of COVID-19 on the RRI of renal transplant recipients and to review the outcomes of patients who underwent renal transplantation (RT) before and during the COVID-19 pandemic.
Methods: The data of 90 recipients were retrospectively reviewed. The age, sex, body mass index, dialysis time before transplantation, history of COVID-19, postoperative serum creatinine levels (1, 6, and 12 months), and complications of the recipients were recorded. The before and after COVID-19 RRI values of 13 recipients at 1 week after transplant and 3 months after COVID-19 were compared. The outcomes and complications of recipients who underwent RT before the COVID-19 pandemic (group 1, n = 47) and during the COVID-19 pandemic (group 2, n = 43) were also compared.
Results: There was a statistically significant difference in terms of the median RRI values of 13 recipients before and after COVID-19 (0.6 [0.53-0.76] vs 0.7 [0.62-0.9], respectively [P = .032]). At the 12-month follow-up, the serum creatinine and estimated glomerular filtration rate levels were found to be statistically significantly higher in group 1 than in group 2 (P = .001 and P = .004, respectively). There was no statistically significant difference between group 1 and group 2 regarding complication rates (53.2% vs 60.5%, respectively; P > .05).
Conclusions: We found that COVID-19 affected RRI values in RT recipients. Our findings show that the outcomes of kidney transplants performed during the COVID-19 pandemic were no worse than those of transplants performed before the pandemic.

Exploring individual's public trust in the NHS Test and Trace System - A pragmatic reflexive thematic analysis.
Internet Interv

Mixed Reality Lab, School of Computer Science, University of Nottingham, Nottingham, United Kingdom.
Context: Digital contact tracing uses automated systems and location technology embedded on smartphone software for efficient identification of individuals exposed to COVID-19. Such systems are only effective with high compliance, yet compliance is mediated by public trust in the system. This work explored the perception of individual's trust and expectation of the broader Test and Trace system in the United Kingdom (UK) with the upcoming release of the National Health Service's (NHS) COVID-19 app as a case example.

Objectives: The aim was to assess the impact of the SARS-CoV-2 pandemic on the prevalence, relative incidence (RI), incidence density (ID), ratio of rate incidence (RRI), rate of incidence density (RID), and relative risks (RR) of healthcare-onset Clostridioides difficile infection (HO-CDI) as well as its correlation with the antibiotic consumption.
Methods: Demographic and analytical data of adult patients exhibiting diarrhoea and testing positive for C. difficile were systematically collected from a tertiary care hospital in Madrid (Spain).

Department of Clinical Pharmacology, Vanderbilt University Medical Center, Nashville, TN, USA.
Purpose: Eighty percent of patients infected by SARS-CoV-2 report persistence of one symptom beyond the 4-week convalescent period. Those with orthostatic tachycardia and orthostatic symptoms mimicking postural tachycardia syndrome, they are defined as Long-COVID POTS [LCP]. This case-control study investigated potential differences in autonomic cardiovascular regulation between LCP patients and healthy controls.

Main Results: Technology transfer can take place at large events, as long as safety protocols are strictly enforced. It is important to disseminate, at these events, the concepts of the Responsible Research and Innovation (RRI). Implications for services: Face-to-face training course is fundamental for training public health professionals.

Article Synopsis
- - Since the COVID-19 pandemic, mental health issues have surged, prompting the need for effective monitoring using wearable devices and mobile health apps that track heart rate variability (HRV) through electrocardiogram (ECG) measurements.
- - This study introduces a new single-arm ECG measurement technique that simplifies the process by only needing one electrode instead of the usual two, making it easier to gather vital mental health data.
- - Experiments showed that the new single-arm ECG method closely correlates with standard lead I ECG readings, particularly in heart rate interval measurements, and could provide reliable insights into mental health conditions with better practical application.
