This is the first report of the genus from the coastal waters of Brazil and brings to 52 the number of valid species for this genus. Additionally, we use the patterns of infection and distribution for species of Rhinebothrium to make predictions of expected diversity within the genus, especially for unsurveyed hosts in endemic marine ecoregions of the world.Metagonimiasis is foodborne intestinal parasitism occurring by the definitive hosts' ingestion of raw or undercooked fish, mostly commonly sweetfish. Most Metagonimus infection is caused by Metagonimus yokogawai but also rarely by Metagonimus takahashii as well as Metagonimus miyatai. Despite recent molecular work on Metagonimus spp., there are still insufficient data to reveal the genetic characteristics of ancient M. yokogawai in a wide geo-historical scope. In this study, we were successful in the analysis of M. yokogawai ancient DNA (aDNA) using coprolite samples retrieved from 16th- to 17th-century Korean mummies. In BLAST and phylogenetic analyses, M. yokogawai 28S rDNA of Korean mummies were clustered along with the 28S rDNA taxa of M. takahashii and M. miyatai in GenBank. Conversely, the cytochrome c oxidase subunit I (COI) of M. yokogawai aDNA from Korean mummies was distinctly clustered apart from M. takahashii and M. miyatai sequences. This study is the first report of its kind to identify M. yokogawai aDNA retrieved from the archaeological specimens and confirms the usefulness of COI in molecular diagnosis of M. yokogawai. Considering the rarity of reports on the genetics of genus Metagonimus spp., our study will be fundamental for the future study of M. yokogawai paleogenetics.The genus Fregata includes 5 species, with 3 recorded in Brazil, with Fregata magnificens being the most abundant. However, its ectoparasitic fauna is still little known. This study aimed to evaluate the incidence of ectoparasites of F. magnificens residing along the coast of Rio de Janeiro and São Paulo collected by 2 animal rehabilitation centers. Samples were collected from 5 frigatebirds of the Instituto Argonauta in São Paulo and 10 frigatebirds of the Centro de Recuperação de Animais Selvagens (CRAS) in Rio de Janeiro. Species of lice were identified using both morphological and molecular methods. Scanning electron microscopy was also used for identification. Colpocephalum spineum, Fregatiella aurifasciata, and Pectinopygus fregatiphagus were identified. All 3 louse species have previously been recorded from this host outside Brazil, but only P. fregatiphagus has been recorded from Brazil. This paper reports the first occurrence of F. aurifasciata and C. spineum in Brazil. It is also the first record of P. fregatiphagus in the state of Rio de Janeiro.

Primary Epstein-Barr virus (EBV) infection presents typically with features of infectious mononucleosis (IM) but it may present with atypical symptoms. We aim to evaluate the epidemiological, clinical and laboratory characteristics of primary EBV infection in children in western Saudi Arabia.

A retrospective analysis of the electronic data of all children who were admitted to the hospital and were tested for EBV-viral capsid antigen (VCA) IgM in the period from 1 January 2018 to 31 December 2019. All data of the children with positive EBV-VCA IgM were collected. Patients were divided into two groups; IM and the non-typical presentations groups.

Fort-two patients had positive EBV-VCA IgM; 71% had IM and 29% had non-typical presentations. IM was more common in early childhood (46.7%). The non-typical presentations were more in infants below 1 year (50%). Adolescents were less affected (6.7% and 16.7%, respectively). Time to diagnose EBV in the non-typical presentations group was longer than IM group; [3.4 (3.2-4.6) vs. 4.7 (4.1-5.5), p = 0.039]. The total leucocytes count was higher in the IM syndrome group compared to the non-typical presentation group [11 (10.3-17.7) vs. 5.5 (4.5-6.4), p < 0.0001].

Primary EBV infection in healthy children in Saudi Arabia occurs more frequently in the younger age groups. IM syndrome occurs more frequently in early childhood. BTK inhibitor in vitro The non-typical presentation occurs more frequently in infants. While adolescents are less commonly affected by primary EBV.

The biological mechanisms of cryotherapy for managing acute pain remain unclear. Additionally, it is unknown whether the effectiveness of cryotherapy depends on the applied temperature. This study aimed to clarify the biological effects of cryotherapy and to examine the therapeutic effects of cryotherapy applied at different temperatures in rats.

This was an experimental study using a rat knee joint arthritis model. Thirty-five Wistar rats were randomly divided into arthritis (AR), arthritis with 5°C cryotherapy (CR-5), arthritis with 10°C cryotherapy (CR-10), and sham-arthritis control (CON) groups. Arthritis was induced by injecting a mixture of kaolin/carrageenan into the right knee joint. Cryotherapy was applied for 7days starting the day after injection by immersing the right knee joint in 5°C or 10°C water. Joint transverse diameter, pressure pain threshold, and pain-related behaviors were assessed for 7days. The number of CD68-positive cells in the knee joint and the expression of calcitonin gene-rbeneficial as a physical therapy modality for pain and swelling management in the acute phase of inflammation. Translational human study is needed to determine the effective cryotherapy temperature for the inflammatory pain.

Low back pain accounts for nearly 4 million emergency department (ED) visits annually and is a significant source of disability. Physical therapy has been suggested as a potentially effective nonopioid treatment for low back pain; however, no studies to our knowledge have yet evaluated the emerging resource of ED-initiated physical therapy. The study objective was to compare patient-reported outcomes in patients receiving ED-initiated physical therapy and patients receiving usual care for acute low back pain.

This was a prospective observational study of ED patients receiving either physical therapy or usual care for acute low back pain from May 1, 2018, to May 24, 2019, at a single academic ED (>91,000 annual visits). The primary outcome was pain-related functioning, assessed with Oswestry Disability Index (ODI) and Patient-Reported Outcomes Measurement Information System pain interference (PROMIS-PI) scores. The secondary outcome was use of high-risk medications (opioids, benzodiazepines, and skeletal muscle relaxants).
