Sweat Characteristics of Cramp-Prone and Cramp-Resistant Athletes
Authors: Miller Kevin C. , McDermott Brendon P. , Yeargin Susan W. 
Published: April 2020

Exercise-associated muscle cramps (EAMCs) are thought to be caused by dehydration and/or electrolyte losses. In this multicenter, cross-sectional study, the authors determined whether sweat rates (SRs), sweat electrolyte concentrations, or sweat electrolyte content differed in athletes with (i.e., crampers) and without (i.e., noncrampers) a history of EAMCs and whether these variables could predict EAMC-prone athletes. Male and female collegiate athletes (N = 350) from 11 sports with (n = 245) and without (n = 105) a self-reported history of EAMCs completed a typical exercise or conditioning session. SRs, calculated from body mass, and posterior forearm sweat were analyzed for sweat sodium concentration ([Na+]sw), sweat potassium concentration ([K+]sw), and sweat chloride concentration ([Cl−]sw). The authors used SRs and sweat electrolyte concentrations to calculate sweat electrolyte content lost. Within each gender, no differences in SRs (204 males, p = .92; 146 females, p = .24); [Na+]sw (191 males, p = .55; 126 females, p = .55); Na+sw content (191 males, p = .59; 126 females, p = .20); [K+]sw (192 males, p = .57; 126 females, p = .87); K+sw content (192 males, p = .49; 126 females, p = .03); [Cl−]sw (192 males, p = .94; 77 females, p = .57); and Cl−sw content (192 males, p = .55; 77 females, p = .34) occurred between crampers and noncrampers. Receiver operating characteristic curve analysis revealed that sweat electrolyte content and SRs were predictive of EAMC-prone athletes in American football (area under curve = 0.65–0.72, p ≤ .005), but not in any other sport. EAMCs may not be solely caused by fluid or electrolyte losses in most athletes. Fluid and electrolyte replacement may help American footballers. Clinicians should individualize fluid and electrolyte replacement and understand different etiologies for EAMCs.

Published: April 2020

Context: Referees’ physical and cognitive performance are important for successful officiating in team sports. There is a lack of research on cognitive performance of referees in general, and none in futsal. Purpose: To assess referees’ performance on the psychomotor vigilance task (PVT) before and after competitive futsal matches during the Football Association (FA) National Futsal League 2015/16. Methods: Fourteen futsal referees (mean [SD] age 34.3 [10.0] y) from the FA National Futsal group were included. The referees were required to undertake a 10-min PVT 60 min before the match kickoff time (pretest) and immediately after matches (posttest). They also completed the Brunel Mood Scale (BRUMS) questionnaire before the prematch PVT and after the postmatch PVT. Result: Data were analyzed by paired t tests comparing prematch and postmatch results. There was a significant difference in BRUMS parameters vigor (9.5 [2.5] prematch vs 6.3 [2.4] postmatch, P = .001) and fatigue (1.4 [1.3] prematch vs 5.6 [3.1] postmatch, P < .001). However, PVT performance was significantly improved (mean reaction time 248.3 [26.2] ms prematch vs 239.7 [22.4] ms postmatch, P = .023). Conclusions: The present results show, contrary to the authors’ initial hypothesis, that psychomotor performance is improved as opposed to decreased after a single match. The postmatch improvement suggests that exercise can acutely enhance cognitive performance, which could be used to inform warm-up practices (eg, optimal duration and intensity) geared toward optimizing referees’ cognitive performance during matches.

Published: April 2020

Background: Data-driven decision making is an accepted best practice in education, but teachers seldom reflect on data to drive their physical activity (PA) integration efforts. The purpose of this study was to explore the impact of a data-sharing intervention with classroom teachers on teacher-directed movement integration and students’ PA and sedentary behavior.Methods: Teacher-directed movement behaviors from 8 classroom teachers in 1 primary school were systematically observed during four 1-hour class periods before (pre) and after (post) an intervention in which teachers individually discussed student movement data with a trained interviewer. Teachers’ K–2 students (N = 132) wore accelerometers for 10 school days both preintervention and postintervention.Results: Multilevel mixed effects regression indicated a nonsignificant increase in teacher-directed movement from preintervention to postintervention (+7.42%,P = .48). Students’ classroom time spent in moderate to vigorous PA increased (males: +2.41 min,P < .001; females: +0.84 min,P = .04) and sedentary time decreased (males: −9.90 min,P < .001; females: −7.98 min,P < .001) postintervention. Interview data inductively analyzed revealed teachers’ perspectives, including their surprise at low student PA during the school day.Conclusions: Findings suggest that sharing data with classroom teachers can improve student PA and decrease sedentary behavior at school.

Published: April 2020

Context: Low back pain (LBP) is a serious health problem, both in the general population as well as in athletes. Research has shown that psychosocial aspects, such as dysfunctional pain responses, play a significant role in the chronification of LBP. Recent research supports the relevance of the multidisciplinary concept of body image in the interpretation of LBP. Objective: To examine the differences in 2 psychosocial aspects, body image and pain responses, between athletes and nonathletes with LBP. Design: Cross-sectional design. Setting: The questionnaires were distributed in the course of LBP treatment. Participants: Data from 163 athletes (mean age = 28.69 [9.6] y) and 75 nonathletes (mean age = 39.34 [12.63] y) were collected. Interventions: Data were collected by questionnaires assessing body image, pain behavior, training activity, and LBP. Main Outcome Measures: To examine group differences between athletes and nonathletes regarding body image and pain behavior, the authors performed 2-way analyses of variance with Bonferroni post hoc tests. Results: The results showed (1) a significant main effect regarding pain responses and body image, showing that participants with eustress endurance or adaptive pain behavior revealed a more positive body image in both groups compared with participants with distress endurance or fear-avoidance behavior, and (2) a significant main effect for the factor group in the body image dimension of physical efficacy, indicating a more positive body image for athletes. Conclusion: These results suggest that considering multiple risk factors for LBP, such as body image and dysfunctional pain behavior, as well as subgrouping, might be valuable for research and for broadening therapy options.

BackgroundImmigrants are at a higher risk of poor mental and physical health. Regular participation in physical activity (PA) and low levels of sedentary time are beneficial for both these aspects of health. The aim was to investigate levels and trends in domain-specific PA and sedentary behaviour in the US. immigrant compared with non-immigrant populations.MethodsFrom the 2007–2016 National Health and Nutrition Examination Survey (NHANES), a total of 25 142 adults (≥18 years) were included in this analysis. PA and sedentary behaviour time were assessed by a questionnaire.ResultsTransit-related PA showed downward linear trends in young immigrant adults (ptrend=0.006) and middle-aged non-immigrant adults (ptrend=0.009). We found significant upward linear trends in sedentary behaviour for both immigrants and non-immigrants across all age groups. For sitting watching TV or videos ≥2 hours/day, there was a downward linear trend in young immigrant adults (ptrend=0.009). For computer use ≥1 hours/day, an upward linear trend in older non-immigrants was found (ptrend=0.024). Young immigrants spent 37.5 (95% CI −55.4 to −19.6) min less than non-immigrants on recreational PA per week. Also, older immigrants spent 23.5 (95% CI 1.5 to 45.6) and 22.5 (95% CI 5.9 to 39.0) min/week more than non-immigrants on recreational PA and transit-related PA, respectively. Last, young and middle-aged immigrants spent 37.6 (95% CI −68.2 to −7.0) and 37.6 (95% CI −99.7 to −9.7) min/day less than non-immigrants on sedentary behaviour, respectively.ConclusionOverall, levels of recreational PA were stable, yet the transit-related PA declined coupled with an increase in sedentary behaviour. US. immigrants exhibit higher levels of transit-PA, lower levels of leisure-time PA and lower levels of sedentary behaviour, in some age groups.
Meanings of Practice, Morals of Error
Authors: Xavier Manuel 
Published: April 2020

Abstract
This paper is about an unsuccessful scientific instrument. Since its conception, the four theodolites Portuguese naval officer, geographer, and later aviation pioneer Carlos Viegas Gago Coutinho (1869–1959) ordered from the Italian maker and engineer Angelo Salmoiraghi (1848–1939), which were used in surveying missions to the African colonies, caused problems and disagreements. From the user’s perspective, the instruments were poorly manufactured; from the maker’s perspective, the user’s incompetence was to blame. By focusing on a well-documented set of scientific instruments, I will analyse social features concerning scientific practice, material culture, and instrument trade. I will show how the meaning of an adapted and untrustworthy instrument changed during practice; how a crisis between distanced user and maker, concerning design, precision, and error, developed; and how a clash for scientific and professional authority intertwined moral and scientific attributes.
A Woodblock’s Career
Authors: Chen Jessie Wei-Hsuan 
Published: April 2020

Abstract
The Antwerp publishing house Officina Plantiniana was the birthplace of many important early modern botanical treatises. Throughout the sixteenth and seventeenth centuries, the masters of the press commissioned approximately 4,000 botanical woodblocks to print illustrations for the publications of the three Renaissance botanists – Rembert Dodoens, Carolus Clusius, and Matthias Lobelius. The woodcuts became one of the bases of early modern botanical visual culture, generating and transmitting the understanding of plants throughout the Low Countries and the rest of Europe. The physical blocks, which are preserved at the Museum Plantin-Moretus in Antwerp, thus offer a material perspective into the development of early modern botany. By examining the 108 woodblocks made for Dodoens’ small herbal, the Florum (1568), and the printing history of a selected few, this article shows the ways in which the use of these woodblocks impacted visual botanical knowledge transfer in the early modern period.
From the Madhouse to the Docu-Museum

Published: April 2020

Abstract
The first electroconvulsive therapy (ECT) device for the treatment of psychiatric disorders was introduced in 1938 by Ugo Cerletti and Lucio Bini, two neuropsychiatrists at the Clinic for Nervous and Mental Diseases, La Sapienza University (Rome). No trace of what became of this device after its use at the clinic can be found until the 1960s, when it appears in a silent black-and-white video dedicated to the university’s recently rehoused and completely renovated Museum of the History of Medicine (MHM), where Cerletti’s original prototype is on display today. However, there is no record of the circumstances under which the electroshock apparatus prototype was transferred from the Clinic of Neuropsychiatry to the museum. Our investigation of this intriguing mystery has uncovered a number of pertinent details that allow us to view the history of the ECT device in a new light. It also emerges that Adalberto Pazzini, the founder of the MHM, played a larger role than was previously thought in this story.

Abstract
Paubrasilia echinata is recognized as the best wood in the manufacture of high-quality bows for string instruments. The wood anatomy of five historic French violin bows of the 19th and 20th century made of Pernambuco wood were investigated in order to reveal the wood anatomic features of these historical bows, to determine which P. echinata morphotype (arruda, café or laranja) was used in their manufacture and to identify the state of origin of the wood. Five bow samples were compared to 33 P. echinata specimens from the Brazilian states of Rio de Janeiro, Bahia, Paraíba and Rio Grande do Norte. The wood anatomical features were compared by means of principal component analysis, which revealed the type of axial parenchyma and percentage of tissue to be the most important to sort specimens. The best wood anatomical features previously described for high-quality bows were corroborated here and the bows in general showed similar wood anatomical features. Based on wood anatomy we found that the violin bows were most similar to the samples from the arruda morphotype derived from the States of Paraíba and Rio Grande do Norte by presenting scanty, unilateral and vasicentric axial parenchyma without confluences forming bands, higher percentage of fibres and lower percentage of axial parenchyma. We can therefore suggest that the historical French violin bows studied here were all made of the arruda morphotype from the Brazilian Northeast region helping explain the preference of the French explorers for this region.
Jesuits in the North American Colonies and the United States
Authors: O’Donnell Catherine 
Published: April 2020

Abstract
From Eusebio Kino to Daniel Berrigan, and from colonial New England to contemporary Seattle, Jesuits have built and disrupted institutions in ways that have fundamentally shaped the Catholic Church and American society. As Catherine O’Donnell demonstrates, Jesuits in French, Spanish, and British colonies were both evangelists and agents of empire. John Carroll envisioned an American church integrated with Protestant neighbors during the early years of the republic; nineteenth-century Jesuits, many of them immigrants, rejected Carroll’s ethos and created a distinct Catholic infrastructure of schools, colleges, and allegiances. The twentieth century involved Jesuits first in American war efforts and papal critiques of modernity, and then (in accord with the leadership of John Courtney Murray and Pedro Arrupe) in a rethinking of their relationship to modernity, to other faiths, and to earthly injustice. O’Donnell’s narrative concludes with a brief discussion of Jesuits’ declining numbers, as well as their response to their slaveholding past and involvement in clerical sexual abuse.
Effect of Periodontal Disease-associated Bacteria on the Formation of Dental Calculus: An In Vitro Study
Authors: Karaaslan Fatih , Demir Turgut , Barış Ozlem 
Published: April 2020

Aim: To investigate whether bacteria that play a major role in periodontal disease pathology and in the formation of dental plaque also affect the formation of dental calculus, which is a predisposing factor for the initiation and progression of periodontal diseases. Materials and Methods: This was an in vitro study, and cultures of bacteria were obtained from the American Type Culture Collection and Department of Biology, Faculty of Science, Atatürk University. Young cultures of bacteria of Streptococcus mutans ( S. mutans), Streptococcus sanguinis ( S. sanguinis), Streptococcus gordonii ( S. gordonii), Aggregatibacter actinomycetemcomitans ( A. actinomycetemcomitans), Porphyromonas gingivalis ( P. gingivalis), Fusobacterium nucleatum ( F. nucleatum), and Corynebacterium matruchotii ( C. matruchotii) were prepared in media containing their specific enriching factors. B2 solid, B4 solid, and B2 liquid media were used to determine active calcification, whereas the mineral salt basal (MSB) medium was used to observe passive calcification. Calcification in the media was measured under light microscopy and in MSB using a spectrophotometer and was recorded as the percent transmittance. Results: S. mutans, S. sanguinis, and S. gordonii showed calcification in the B2 medium. S. mutans, S. sanguinis, S. gordonii, and C. matruchotii demonstrated calcification in MSB. A. actinomycetemcomitans, P. gingivalis, and F. nucleatum did not show any calcification. Conclusions: It was concluded that streptococci present in dental plaque take part in the formation of dental calculus, whereas periodontopathogens have no role in the formation of dental calculus.

Published: April 2020

Aim: To characterize the lip print pattern in a study population and to ascertain its potential for sex determination. Materials and Methods: A cross-sectional study was conducted among 300 undergraduate students (144 males and 156 females). Simple random sampling was used. Lip prints were obtained with lipstick and were classified according to Suzuki and Tsuchihashi classification. Data were analyzed with the Statistical Package for Social Sciences (SPSS) version 22 (IBM Corp., Armonk, NY, USA). The prevalence of lip print patterns was presented as frequencies and percentages, and the test of significance of gender difference was done with chi-square at the 95 percent confidence interval. Result: No two lip print patterns were found to be the same. There was a significant difference in the lip print patterns of females and males. In females, the pattern with the highest frequency was type II (40.4%). This was followed by type I (36.5%), type III (13.5%), type V (7.1%), and type IV (2.6%). In males, the pattern with the highest frequency was type IV (28.5%). This was followed by type III (26.4%), types I and V (each 16.0%), and type II (13.2%). When both sexes were considered together, type II was the most frequent pattern. Conclusion: Lip print is unique to individuals and it has potential for sex determination. The most prevalent patterns in females and males were type II and type IV, respectively.

Published: April 2020

Abstract
Introduction
The population rate of familial cluster headache (CH) has been reported to be as high as 20% however this varies considerably across studies. To obtain a true estimate of family history in CH, we conducted a systematic review and meta-analysis of previously published data.

Methods
Our systematic review involved a search of electronic databases (Medline, EMBASE, PubMed, CINAHL) to identify and appraise studies of interest utilising the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines. To further ameliorate the accuracy of our analysis we included an additional unpublished cohort of CH patients recruited at a tertiary referral centre for headache, who underwent detailed family history with diagnostic verification in relatives. Data was extracted and meta-analysis conducted to provide a true estimation of family history.

Results
In total, we identified 7 studies which fulfilled our inclusion criteria. The estimated true prevalence of CH patients with a positive family history was 6.27% (95% CI:4.65–8.40%) with an overall I2 of 73%. Fitted models for gender subgroups showed higher estimates 9.26% (95% CI: 6.29–13.43%) in females. However the I2 for the female model was 58.42% and significant (p = 0.047).

Conclusion
Our findings estimate a rate of family history in CH to be approximately 6.27% (95% CI: 4.65–8.40%). While estimates were larger for female probands, we demonstrated high heterogeneity in this subgroup. These findings further support a genetic role in the aetiology of CH.

AbstractBackgroundTreatment with onabotulinumtoxin A (BT-A) is safe and effective for chronic migraine (CM). Several studies assessed possible predictors of response to treatment with BT-A, but there is little knowledge on the frequency and predictors of sustained response. The aim of this study was to evaluate sustained response to BT-A in patients with CM.Main bodyIn this prospective open-label study, 115 patients with CM and treated with BT-A were consecutively enrolled in two Italian headache centers and followed up for 15 months. Anytime responders were defined as those patients who achieved a ≥ 50% reduction in headache days during any three-month treatment cycle compared with the 3 months prior to initiation of BT-A treatment. Sustained responders were defined as those who achieved a ≥ 50% reduction in headache days within the third treatment cycle and maintained response until the end of follow-up. Non-responders were defined as those patients who never achieved a ≥ 50% reduction in headache days during the follow-up. Headache characteristics prior to BT-A treatment were assessed in order to evaluate their ability in predicting treatment response.The 115 enrolled patients (84.3% female; median age 50 years) had a median migraine duration of 30 years (interquartile range 22–38). At the end of follow-up, 66 patients (57.4%) were classified as anytime responders. Among the 51 patients who achieved a clinical response within the third month of treatment, 33 (64.7%) were sustained responders. Patients with sustained response had a lower CM duration (median 31 vs 65 months;P = 0.030) and a lower number of headache days (median 25 vs 30;P = 0.013) at baseline compared with non-responders.ConclusionsAbout two thirds of patients who gain ≥50% response to BT-A within the third cycle of treatment maintain this positive response over time. More recent onset of CM and more headache-free days at baseline are associated with sustained response. We suggest not to delay preventive treatment of CM with BT-A, in order to increase the likelihood to achieve sustained clinical response.
