Renwick","doi":"10.1097/SLA.0000000000002052","DOIUrl":"https://doi.org/10.1097/SLA.0000000000002052","url":null,"abstract":"Our publication in the Journal of Applied Biomechanics examining various algorithms to determine intramuscular electromyography (EMG) onset1 has received considerable interest. We have similarly published work looking at various algorithms for surface EMG onset2 and posted all of our raw EMG data in a public repository (https://github.com/TenanATC/EMG). This “Open Science” approach has led to a number of thoughtful discussions with fellow researchers on the detection of EMG onset. The algorithm type that performed best in both our surface and intramuscular EMG studies was Bayesian changepoint (bcp) analysis. Based on constructive conversations with researchers using our data and the algorithms assessed in our manuscripts, we would like to address a concern that has arisen with reproducing our bcp analysis. Specifically, our manuscripts utilized the version 4.0.0 bcp package in the R programming language. At the time of this letter, the bcp package has been updated to 4.0.3 by the maintainer, Dr. Xiaofei Wang. In version 4.0.0, our analyses continually demonstrated that, for detecting a single EMG onset, the “parameter of the prior on changepoint probabilities” or p0 argument should be “0” for optimal detection.1,2 Recent updates to the bcp package by Dr. Wang, described as “streamlining the C code” (personal communication), have resulted in the bcp algorithm returning a vector of zeros for the posterior probability of a changepoint when the argument p0 is set to “0.” In conversation with Dr. Wang, we agree that the current version of bcp (4.0.3) is likely more conceptually correct than the version used in our manuscripts (4.0.0). Indeed, we found it a bit peculiar that the bcp “p0 = 0” argument continually rendered the best EMG onset detection, but the purpose of our manuscripts was to examine the various algorithms in their current form for onset detection. We did not aim to critique or investigate the various algorithms themselves. When using version 4.0.0 of the bcp package for R, our finding that the “p0 = 0” argument produces the best onset detection for a single EMG onset is correct; an extremely small p0 does make conceptual sense for detecting a single EMG onset, in which one might expect an abrupt change in the time series (ie, rapid muscle contraction as opposed to a slow ramping contraction). The question remains, “How should we consider using bcp analysis for EMG onset?” First, we would like to reiterate what we stated in our original manuscript: “While all top Bayesian algorithms in the present study used p0 = 0, it should not be expected that this setting is appropriate in all cases.” Second, pilot work by our group suggests that using the current bcp package (version 4.0.3) with the p0 argument set to an extremely small value (ie, <.0001) renders onsets similar to our manuscripts. Third, the R programming language is capable of loading previous versions of R packages using either the devtools package (ie, “install_version”) or dire","PeriodicalId":16054,"journal":{"name":"Journal of Herpetological Medicine and Surgery","volume":"119 1","pages":"5 - 5"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81556025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study therefore aimed to calculate reference intervals (RI) for thyroid hormones and iodine concentrations by species, sexes, and seasons in four species of adult Mediterranean tortoises (Testudo spp.) and to evaluate possible correlations between plasma thyroid hormones, serum iodine, plasma protein, and increased liver and kidney values. Thyroid hormones (total tetraiodothyronine [tT4], free tetraiodothyronine [fT4], total triiodothyronine [tT3], and free triiodothyronine [fT3]) were measured in plasma from adult, healthy Hermann's (Testudo hermanni, n = 255), spur-thighed (Testudo graeca, n = 89), marginated (Testudo marginata, n = 72), and Russian tortoises (Testudo horsfieldii, n = 30). Species, sex, and seasonal variations were determined by Bayesian information criterion (BIC), and correlations between thyroid hormones, protein, iodine, and increased liver/kidney values were evaluated by Spearman's rank correlation test. Total T4 did not reveal any species, sex, or seasonal differences (RI: 0.102–0.455 µg/dl), while seasonal differences were found for fT4 (RI: spring 0.624–9.012; summer 0.379–5.476; fall 0.376–5.426 pmol/L). The tT3 concentrations differed significantly depending on species, season, and the interaction of species × season. Seasonal differences were also found for fT3 and iodine. Several significant (P ≤ 0.05) correlations were detected between the analytes, including a positive correlation between tT4 and fT4. These results provide a tool for the evaluation of thyroid hormone concentrations in Mediterranean tortoises and confirm the influence of season on thyroid function in these animals.","PeriodicalId":16054,"journal":{"name":"Journal of Herpetological Medicine and Surgery","volume":"128 1","pages":"84 - 95"},"PeriodicalIF":0.0,"publicationDate":"2022-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74589312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Immediately following blood collection, a swelling was noted in the region of the heart. The snake was unable to recover from anesthesia and the heart subsequently stopped based on doppler assessment. The cause of death at necropsy was determined to be acute cardiac tamponade secondary to hemopericardium, with no additional histologic lesions noted within the heart. This is the first report of cardiac tamponade following cardiocentesis in a snake without a diagnosed cardiopathy, suggesting that risk factors should be considered when performing cardiocentesis in this species.","PeriodicalId":16054,"journal":{"name":"Journal of Herpetological Medicine and Surgery","volume":"143 1","pages":"116 - 118"},"PeriodicalIF":0.0,"publicationDate":"2022-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73401898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonselective COX-1 and COX-2 inhibitors, such as ketoprofen, could therefore reduce inflammation more effectively than preferential COX-2 inhibitors in reptiles. The objective of this study was to evaluate potential adverse effects of ketoprofen in bearded dragons (Pogona vitticeps). Thirteen adult bearded dragons were divided into three groups receiving daily intramuscular injections for 14 days in a blinded randomized study design. Group 1 (n = 5) received saline, Group 2 (n = 4) received ketoprofen at 2 mg/kg (diluted 1:10 with saline) and Group 3 (n = 4) received ketoprofen at 20 mg/kg (undiluted). Biochemical values, fecal occult blood (FOB) tests, and blood clotting time were assessed before and after the 2-wk treatment. Renal, digestive, hepatic, and muscular histopathology was evaluated. Clinically, injection-site reactions were noted in Group 3 only (n = 1/4). No other clinical adverse effects were detected. No changes were detected in plasma biochemical values and clotting times before and after treatments, nor were changes detected between control and treatment groups. No lesion associated with ketoprofen toxicity was detected on histologic examination of the kidney, liver, and gastrointestinal tract. Lesions of muscular necrosis at the injection sites were of higher magnitude in Group 3 compared to Group 1. In conclusion, daily intramuscular administration of diluted ketoprofen at 2 mg/kg for 14 days did not cause adverse effects in a small number of bearded dragons, whereas severe muscular necrosis was detected at 20 mg/kg.","PeriodicalId":16054,"journal":{"name":"Journal of Herpetological Medicine and Surgery","volume":"14 1","pages":"123 - 129"},"PeriodicalIF":0.0,"publicationDate":"2022-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82835557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
