Dental professionals work closely with patients and present an increased risk of person-to-person transmission of SARS-CoV-2. Moreover, the use of ultrasonic scalers, air-water syringes, and slow and high-speed handpieces, which are common in the dental office, generate spatter and aerosol. The use of preprocedural mouthrinses has been proposed to reduce the viral load in saliva and oropharyngeal tissues, thus decreasing viral load in dental aerosol. Although some mouthrinses demonstrates an antiviral effect, there is limited evidence about the clinical efficacy of any mouthrinse in the reduction of SARS-CoV-2 in the dental aerosol. We hypothesized that mouthrinses may reduce SARS-CoV-2 viral load in the oropharynx and its fluids reducing viral load in dental aerosol. The potential use of mouthrinses is discussed, along with proposal of in vitro and clinical studies, in order to evaluate this hypothesis. If this hypothesis holds true, dental professionals and patients may benefit from the routine use of preprocedural mouthrinses.European Union (EU) and global sustainability policies emphasize the need to replace contentious pesticides with safe, efficient, and cost-effective alternatives to ensure sustainable food production. However, R&D for alternatives to contentious pesticides are lagging behind and need to be broadened. Here, we discuss how RNAi-based technology can contribute to pesticide risk reduction.Kidney transplant is currently the elective treatment of choice for end-stage renal disease. Laparoscopic living donor nephrectomy (LLDN) has substantial advantages over open nephrectomy. Chylous ascites (CA) is a rare surgical complication after the LLDN; there are few reports in the literature. We present a case report of a 58-year-old woman who started CA on the 21st day post operation. C381 The recommended initial therapeutic approach to suspend the fat in the diet and place percutaneous drainage was not enough. It was decided to jointly introduce fasting and total parenteral nutrition with the administration of octreotide, resolving the complication completely in 15 days with no need for the patient to undergo surgery. The conservative management, during the first 4 to 8 weeks after the diagnosis is the best option. Surgery is generally recommended if conservative management fails. The prevalence of CA varied between 0% and 6.2% of LLDNs. In our experience of 87 LLDNs, we only presented 1.15% for this complication. There are 62 cases reported in the international literature. The mean presentation was 14 days after LLDN. All patients underwent conservative treatment, and only 15 patients (24%) went to surgery after the failure of conservative management. It would be highly useful, considering the disparity of the prevalence, if the bibliographic reports detail what hemostatic and sealing techniques are used in an LLDN. In this way it would be possible to identify which factor affects a complication like this one.

Immunosuppressive treatment is often interrupted in the first months following kidney transplant failure (KTF) to limit side effects. The aim of this study was to assess the effect of prolonged treatment (PT) of more than 3 months' duration after KTF on HLA sensitization and treatment tolerance.

We performed a retrospective observational study involving 119 patients with KTF in 3 French kidney transplant centers between June 2007 and June 2017. Sensitization was defined as the development of HLA donor-specific antibodies (DSA).

In the PT group receiving calcineurin inhibitor (CNI) treatment, 30 of 52 patients (57.7%) were sensitized vs 52 of 67 patients (77.6%) who had early cessation of treatment (P= .02). The results were confirmed by multivariate analysis (odds ratio [OR]= 0.39, 95% confidence interval [CI] [0.16; 0.98], P= .04). The development of de novo DSAs after CNI treatment (n= 63/90 [70.0%]) was significantly more frequent than during CNI treatment, (n= 18/52 [34.6%], P= .01). Panel-reactive antibody≥85% was lower in the PT group in multivariate analysis (OR= 0.28, 95% CI [0.10; 0.78], P=.02). No differences in the rates of infection, cardiovascular complications, neoplasia, and deaths were observed between the 2 groups. In multivariate analysis, continuation of corticosteroid treatment had no influence on sensitization but was associated with a higher rate of infection (OR= 2.66, 95% CI [1.09; 6.46], P= .03).

Maintenance of CNI treatment after return to dialysis in patients requesting a repeat transplant could avoid the development of anti-HLA sensitization with a good tolerance.

The long-term outcomes after living donor liver transplantation (LDLT) vs deceased donor liver transplantation (DDLT) for hepatocellular carcinoma (HCC) remain controversial. We compared the long-term outcomes between LDLT and DDLT in patients with HCCs within or beyond the Milan criteria.

This retrospective study included 896 patients who underwent liver transplantation (829 LDLTs and 67 DDLTs) for HCC from June 2005 to May 2015. Recurrence-free survival (RFS) and overall survival (OS) were estimated using the Kaplan-Meier method with log-rank test.

RFS at 1, 3, 5, and 10 years after LDLT was 89.6%, 84.6%, 82.4%, and 79.6%, respectively, and, after DDLT, was 92.4%, 86.2%, 82.4%, and 82.4%, respectively, and OS at 1, 3, 5, and 10 years after LDLT was 96.1%, 88.1%, 85.6%, and 82.7%, respectively, and, after DDLT, was 97.0%, 83.6%, 82.1%, and 77.3%, respectively, with no significant differences in RFS (P= .838) or OS (P= .293) between groups. No statistically significant differences after LDLT or DDLT were identified in RFS (89.8% vs 98.1%, respectively, at 5 years; P= .053) or OS (90.4% vs 90.6% , respectively, at 5 years; P= .583) for HCCs meeting the Milan criteria as well as for those beyond the Milan criteria (RFS, 37.8% vs 28.6%, respectively, at 5 years; P= .560 and OS, 57.3% vs 50.0%, respectively, at 5 years; P= .743).

Patients who underwent LDLT for HCCs showed comparable long-term outcomes to patients who underwent DDLT. Patients with HCCs within the Milan criteria demonstrated acceptable long-term outcomes after both LDLT and DDLT.

Automated peritoneal dialysis (APD) treatment for end-stage kidney disease affords patients a degree of autonomy in everyday life. Clinical investigations of their energy expenditure (EE) are usually based on resting EE, which could mask day and night variations in EE. The aim of this study, therefore, was to compare the components of EE in APD patients and healthy control (C) subjects.

Patients treated with APD for more than 3 months were compared with C volunteers matched for age and lean body mass (LBM). Biochemical analyses were performed and body composition was determined by DEXA to adjust EE to LBM. Total EE, its different components and respiratory quotients (RQ) were measured by a gas exchange method in calorimetric chambers. Spontaneous total and activity-related EE (AEE) were also measured in free-living conditions over 4 days by a calibrated accelerometer and a heart rate monitor.

APD (n=7) and C (n=7) patients did not differ in age and body composition. REE did not differ between the two grher prandial increase in EE, a lower activity-related EE and higher resting and nocturnal RQ than healthy subjects.

Estimates of energy requirements, based on measured or predicted resting energy expenditure (REE), are needed to avoid undernutrition or overnutrition (and their clinical consequences) in elderly subjects. The aims of this systematic review were to evaluate the prediction accuracy of REE in healthy elderly subjects and to ascertain which equation is more reliable at group level and/or individual level.

Studies assessing prediction of REE in general elderly population were systematically searched using PubMed, EMBASE, Web of Science and CINAHL until March 2020. Prediction accuracy of REE was assessed at both group (bias) and individual (precision) level for each equation.

Fourteen studies met the inclusion criteria of this systematic review. Bias was reported in 8 papers and calculated in another 5 from absolute values. There was a prevalent tendency towards an overestimation of REE across the studies. The least bias was observed for the Mifflin (-0.3%) and Harris-Benedict (+2.6%) equations, with values ed to evaluate the variability and accuracy of REE in the elderly general population.

Systems medicine is based on approaches taken from systems biology, omics research, bio-informatics and network theory. It promises to facilitate a better understanding of the causes of diseases, detection at an earlier stage, and the use of tailor-made approaches to prevention and therapy. This study provides information on how systems medicine could be incorporated into the German healthcare system.

In a Policy Delphi, consensus and divergence was elicited on whether experts believed systems medicine could be incorporated into the German healthcare system by 2030. Additionally, factors that could influence the implementation process were analysed. 11 theses on potential systems medicine developments and 193 arguments on influencing factors were evaluated. Experts from health and health-related fields were selected using "purposive sampling".

The experts interviewed expressed their trust in the provision of a legal-political framework, though they remained uncertain as to whether the necessary social discourse on the ethical and cultural questions surrounding systems medicine would occur. They do not (currently) expect systems medicine to be implemented by 2030.

Systems medicine is currently regarded as a visionary concept. As such, it would be premature to attempt to judge the success of the translation process at this stage. The results can help with the identification of the challenges involved in implementation, and the action required to achieve this aim.

While current data of plastic pollution include marine and terrestrial ecology, the impacts of degraded or intentionally produced microscopic-sized plastics on human health remain unknown. Here, we are proposing the usage of pluripotent stem cells, modern transcriptomics, and bioinformatics as a unique scientific tool to define the link between environmental and intracellular pollution, its outcome on early human development and origin of diseases. This commentary is an urgent appeal to the scientific and policy communities to invest more time and resources to establish reliable standards and methods to define and address the consequences of plastic pollution on human health.
