Rapid antigen detection (RAD) tests for the detection of SARS-CoV-2 are simpler, faster, and less expensive than the reverse-transcription polymerase chain reaction (RT-PCR) that is currently considered the gold standard for the diagnosis of coronavirus disease 2019 (COVID-19). The objective of this study was to determine the performance of the PANBIO COVID-19 Ag RAD (Abbott) test, a lateral flow immunoassay that detects the nucleocapsid protein, using as a reference RT-PCR method the Cobas®8800 System (Roche Diagnostics). This prospective study was conducted in a tertiary Children's Hospital and included individuals aged ≤16 years with COVID-19-related symptoms or epidemiological criteria for COVID-19. Two nasopharyngeal samples were collected to perform the PANBIO RAD test and RT-PCR. Of 744 children included, 51 (6.86%) had a positive RT-PCR result. The RAD test detected 42 of 51 PCR-positive children while there were no false-positive results. The overall sensitivity and specificity were 82.35% (95% CI, 71.9%-92.8%) and 100%, respectively. Sensitivity was >95% in symptomatic children. The assay performed poorly in asymptomatically infected children. In agreement with previous studies in adults, the PANBIO RAD test can be useful in screening for COVID-19 in children admitted with symptoms suggestive of the disease, especially in the first days of the illness.The medial tarsal area is a commonly used donor site for skin grafts to the digits and toes, with good color and texture match as well as a concealable donor site scar. Yet, there has been no report as a perforator free flap donor site. The purpose of this report is to present a new perforator flap harvested from medial tarsal region. We present a case of a soft tissue defect of the fifth toe due to essential thrombocythemia (ET), successfully treated with a free medialis tarsus flap (MTF) transfer. A 62-year-old male with ET suffered from the right fifth toe necrosis caused by digital artery thrombosis. ATG-019 After the manifestation of the necrosis, necrotic tissue was completely debrided, which resulted in a 3 × 1.5 cm skin defect with exposure of the tendon and the phalangeal bone. Sixth days after debridement, a 4.5 × 1.7 cm MTF was harvested transversely and inferiorly to the right medial ankle, locating the preoperatively detected posterior tibial artery perforator (PTAP) in the flap. Perforator-to-perforator anastomosis was done using the dorsal metatarsal artery perforator and the subcutaneous vein as recipient vessels. The donor site was closed primarily. Postoperative course was uneventful, and the reconstruction preserved the toe length and functions of extension and flexion at 9 months postoperatively. The patient could walk with conventional shoes by himself. MTF may be an option for small skin defect in the digits and toes where skin graft is not indicated.

Behaviours that challenge (BtC) reflect the most costly and burdensome aspects of dementia where non-pharmacological interventions rather than antipsychotic medication have been recommended as first-line approaches for over a decade (NICE 2006). This paper outlines professionals' views about their application of the Dementia NICE Guideline 97 (2018) and a British Psychological Society, Division of Clinical Psychology (BPS-DCP) Briefing paper (2013) on alternatives to antipsychotics.

A mixed-methods 34-item e-survey, with five items about the use of the NICE Guideline 97 (2018) and the BPS-DCP Briefing paper (2013) for the management of BtC, was conducted. Participants were recruited through multidisciplinary professional dementia networks across the United Kingdom. Quantitative data were descriptively summarized and thematic analysis of open-ended questions undertaken.

Two hundred and forty-seven participants completed the questions relating to guidelines. Mean ratings of 'moderately useful' for both thnterventions, which are the first-line treatments for BtC. The BPS Guidelines on 'Alternatives to antipsychotics' (2013) were seen as having good structured advice for allocating non-pharmacological resources but were lacking in flexibility for meeting individual needs or what might be an acceptable fit for clinical services. The findings suggest that we need to develop UK-wide bespoke specific advice for practitioners and services for both the use and the delivery of non-pharmacological evidence-based interventions for BtC.How organisms integrate metabolism with the external environment is a central question in biology. Here, we describe a novel regulatory small molecule, a proteogenic dipeptide Tyr-Asp, which improves plant tolerance to oxidative stress by directly interfering with glucose metabolism. Specifically, Tyr-Asp inhibits the activity of a key glycolytic enzyme, glyceraldehyde 3-phosphate dehydrogenase (GAPC), and redirects glucose toward pentose phosphate pathway (PPP) and NADPH production. In line with the metabolic data, Tyr-Asp supplementation improved the growth performance of both Arabidopsis and tobacco seedlings subjected to oxidative stress conditions. Moreover, inhibition of Arabidopsis phosphoenolpyruvate carboxykinase (PEPCK) activity by a group of branched-chain amino acid-containing dipeptides, but not by Tyr-Asp, points to a multisite regulation of glycolytic/gluconeogenic pathway by dipeptides. In summary, our results open the intriguing possibility that proteogenic dipeptides act as evolutionarily conserved small-molecule regulators at the nexus of stress, protein degradation, and metabolism.

The first wave of coronavirus disease-2019 (COVID-19) dramatically affected the Transfusion Medicine Unit of the Azienda Unità Sanitari Locale - Istituto di Ricovero e Cura a Carattere Scientifico (AUSL-IRCCS) di Reggio Emilia, which faced a total rearrangement of the procedures for donors and patients. This study aims to assess the major implications of COVID-19 on our department, focusing on the blood transfusion chain and therapies, in order to support transfusion specialists in seeking efficient ways to face similar future emergencies.

This retrospective study compares our Transfusion Medicine Unit data collected between February and May 2020 with the same period in 2017-2019. Data on red blood cells and platelets donations, transfusions and clinical procedures were collected as aggregates from our internal electronic database.

During the lockdown, donor centres were re-organized to reduce the risk of contagion and avoid unnecessary blood collection. Blood donations were re-scheduled to meet the decrease in elective surgery; consequently, plateletapheresis was implemented to supply the reduction of buffycoat-derived platelets.
