BACKGROUND:
Cognitive impairment is common in older surgical patients and is associated with postoperative delirium. However, cognitive function is inconsistently assessed preoperatively, leading to missed opportunities to recognize vulnerable patients. We designed a prospective cohort study to assess the agreement of the Mini-Cog screening tool administered in the preoperative clinic (clinic-day test) or immediately before surgery (surgery-day test) and to determine whether a positive screening for cognitive dysfunction in the surgery-day test is associated with postoperative delirium in the postanesthesia care unit (PACU).

METHODS:
This was a cohort study of patients aged 65–89 years, scheduled for elective, inpatient surgery under general anesthesia between June 20, 2018 and August 3, 2018. Mini-Cog test scores were obtained during a clinic-day test and surgery-day test. The Short Confusion Assessment Method was performed in the PACU. Agreement between Mini-Cog clinic-day and surgery-day test scores was estimated using an ordinally weighted kappa statistic, κ. Multivariable logistic regression was used to determine whether there was an association between a positive screen for cognitive impairment and PACU delirium. Odds ratio analysis was performed to determine whether the Mini-Cog score was associated with PACU delirium.

RESULTS:
Of 128 patients meeting eligibility criteria, 80 patients were enrolled. Ten had cognitive impairment based on the Mini-Cog clinic-day test score, while 70 did not. Age, sex, race, education level, subjective memory impairment, and American Society of Anesthesiologists (ASA) physical status were equivalent in the 2 groups. The mean number of days between the clinic-day score and the surgery-day score was 8.4 days (standard deviation [SD] = 6.9). Mini-Cog clinic-day and surgery-day scores had high agreement (κ = 0.78; 95% confidence interval [CI], 0.69–0.87; P < .001), and both scores were highly predictive of PACU delirium. Patients with Mini-Cog surgery-day scores compatible with cognitive impairment (Mini-Cog scores ≤2) had an estimated 12.8 times higher odds of PACU delirium compared to patients with normal cognitive function or Mini-Cog scores >2 (odds ratio [OR] = 12.8; 95% CI, 2.6–63.8, P = .002). Similarly, patients with Mini-Cog clinic-day test scores compatible with cognitive impairment had an estimated 29 times higher odds of PACU delirium compared to patients with normal cognitive function (OR = 29.0; 95% CI, 2.6–63.8, P < .001).

CONCLUSIONS:
These data support the approach of using the Mini-Cog on the day of surgery to screen for cognitive impairment in older patients. Importantly, Mini-Cog surgery-day test scores compatible with cognitive impairment (≤2) were strongly associated with PACU delirium.
Ease of Application of Various Neuromuscular Devices for Routine Monitoring

Published: September 2020

BACKGROUND:
Subjective evaluations to confirm recovery from neuromuscular blockade with a peripheral nerve stimulator (PNS) is inadequate. Quantitative monitors are the only reliable method to confirm adequate recovery of neuromuscular function. Unfortunately, many clinicians are unfamiliar with such devices and there is concern that the introduction of objective monitoring would be exceedingly laborious and could cause workflow delays. This study investigates how long it takes experienced nurse anesthetists to apply various neuromuscular devices as well as their perception regarding the ease of application.

METHODS:
Twenty nurse anesthetists were consented and participated in an educational session that familiarized them with 3 devices: SunStim Plus PNS (SunMed, Grand Rapids, MI), the acceleromyography-based IntelliVue NMT device (Philips, Amsterdam, the Netherlands), and electromyography-based TetraGraph device (Senzime B.V., Uppsala, Sweden). Participants were timed while placing each monitor on patients in a real-world setting. For the quantitative devices (IntelliVue NMT and TetraGraph), participants were also timed when obtaining calibrated baseline train-of-four (TOF) ratios. Friedman test and pairwise Wilcoxon signed-rank tests were used to evaluate the difference in time to connect different devices. Participants were surveyed about how easy they found it to utilize these devices.

RESULTS:
After adjusting for multiple comparison, time to connect was significantly less for PNS (median, 29; range, 16–58 seconds) compared to either the TetraGraph device (median, 62.8; range, 32–101 seconds; P < .001) or the IntelliVue NMT device (median, 46; range: 28–90 seconds; P < .001). The difference in time to connect between the TetraGraph device and the IntelliVue NMT device was not statistically significant (P = .053), but it took significantly less time to calibrate the TetraGraph device than the IntelliVue NMT device (median difference, −16; range, −88 to 49 seconds; P = .002). The participants found applying either the IntelliVue NMT device (P = .042) or the TetraGraph device (P = .048) more difficult than applying a PNS while finding it easier to calibrate the TetraGraph device versus the IntelliVue NMT device (P < .001).

CONCLUSIONS:
It takes 19 seconds longer to apply a quantitative neuromuscular monitor (the IntelliVue NMT device) than a PNS. While this difference reached significance, this relatively minimal additional time represents an inappropriate barrier to the application of quantitative monitors. Regardless of which quantitative monitor was utilized, these nurse anesthetists found the application and utilization of such devices relatively straightforward.
Development and plasticity of the corpus callosum
Authors: De León Reyes Noelia S. , Bragg-Gonzalo Lorena , Nieto Marta 
Published: September 2020

ABSTRACT
The corpus callosum (CC) connects the cerebral hemispheres and is the major mammalian commissural tract. It facilitates bilateral sensory integration and higher cognitive functions, and is often affected in neurodevelopmental diseases. Here, we review the mechanisms that contribute to the development of CC circuits in animal models and humans. These species comparisons reveal several commonalities. First, there is an early period of massive axonal projection. Second, there is a postnatal temporal window, varying between species, in which early callosal projections are selectively refined. Third, sensory-derived activity influences axonal refinement. We also discuss how defects in CC formation can lead to mild or severe CC congenital malformations.

Abstract
The traditional preparation of non-fullerene acceptors (NFAs) via Knoevenagel condensation reaction (KCR) of aldehyde and active methylene leaves vulnerable and reversible exocyclic vinyl bonds in structures, which undermine the intrinsic chemo- and photostability of NFAs. In this work, we demonstrate a new access to acceptor-donor-acceptor (A-D-A) NFAs via Stille coupling between new electron deficient groups and classic donor core in over 90% yield, wherein the robust carbon-carbon bonds, replacing the exocyclic double bonds from traditional KCR, result in stable A-D-A acceptors, Q1-XF (X representing 0, 2 and 4 fluorine atoms, respectively). Among the three studied examples, Q1-4F exhibits improved optoelectronic and electron transport properties, leading to the best photovoltaic performance with optimal charge kinetics for Q1-4F based OSCs. Overall, this strategy can lead to a new way for developing stable photovoltaic materials.
Investigating the Matching Relationship between Physical Exercise and Stereotypic Behavior in Children with Autism

Published: September 2020

ABSTRACT

Purpose
Physical exercise has been shown to be effective in reducing stereotypic behaviors in children with autism spectrum disorder. One possible mechanism concerns the matching hypothesis between exercise and behavior. The present study sought to examine this matching exercise–behavior relationship.

Methods
Participants (N = 21, 17 males and 4 females, M
age = 11.07 ± 1.44 yr, M
height = 1.46 ± 0.99 m, and M
weight = 40.60 ± 8.25 kg), with observable forms of hand-flapping and body-rocking stereotypic behaviors, underwent three separate days of conditions, one for the control condition, one for the 10-min ball-tapping exercise condition, and one for the 10-min jogging condition, in a randomized order. The frequency of each type of stereotypic behavior was videotaped from 15 min before to 60 min after the exercise.

Results
Results revealed that only hand-flapping stereotypic behaviors were significantly reduced in the ball-tapping exercise condition (P < 0.017), whereas only body-rocking stereotypic behaviors were significantly reduced in the jogging exercise condition (P < 0.017). However, the behavioral benefit diminished at 45 min after the respective exercise.

Conclusion
Physical exercise should be topographically matched with stereotypic behavior to produce desirable behavioral benefits in children with autism spectrum disorder.

ABSTRACT

Purpose
This study aimed to determine the association between light-intensity physical activity and the incidence of all-cause and cardiovascular mortality in patients with peripheral artery disease (PAD) limited by claudication followed for up to 18.7 yr.

Methods
A total of 528 patients with PAD and claudication were screened in Baltimore between 1994 and 2002, and 386 were deemed eligible for the study. At baseline, patients were classified into three physical activity groups: 1) physically sedentary, 2) light intensity, and 3) moderate to vigorous intensity based on a questionnaire. All-cause and cardiovascular mortality of patients through December 2014 was determined using the National Death Index and the U.S. Department of Veterans Affairs and the U.S. Department of Defense Suicide Data Repository.

Results
Median survival time was 9.9 yr (interquartile range, 4.9–15.7 yr; range, 0.38–18.7 yr). During follow-up, 257 patients (66.6%) died, consisting of 40/48 (83.3%) from the sedentary group, 135/210 (64.3%) from the light-intensity group, and 82/128 (64.0%) from the moderate- to vigorous-intensity group. For all-cause mortality, light-intensity activity status (hazard ratio [HR] = 0.523, P = 0.0007) and moderate- to vigorous-intensity status (HR = 0.425, P < 0.0001) were significant predictors. During follow-up, 125 patients died because of cardiovascular causes (32.4%), in which light-intensity activity status (HR = 0.511, P = 0.0113) and moderate- to vigorous-intensity activity status (HR = 0.341, P = 0.0003) were significant predictors.

Conclusions
Light-intensity physical activity is associated with nearly 50% lower risk of all-cause and cardiovascular mortality in high-risk patients with PAD and claudication. Furthermore, moderate- to vigorous-intensity physical activity performed regularly is associated with 58% and 66% lower risk of all-cause and cardiovascular mortality, respectively. The survival benefits associated with light-intensity physical activity make it a compelling behavioral intervention that extends beyond improving ambulation.

Background: Data sharing is now a mandatory prerequisite for several major funders and journals, where researchers are obligated to deposit the data resulting from their studies in an openly accessible repository. Biomedical open data are now widely available in almost all disciplines, where researchers can freely access and reuse these data in new studies. We aim to study the BioLINCC datasets, number of publications that used BioLINCC open access data, and the impact of these publications through the citations they received. Methods: As of July 2019, there was a total of 194 datasets stored in BioLINCC repository and accessible through their portal. We requested the full list of publications that used these datasets from BioLINCC, and we also performed a supplementary PubMed search for other publications. We used Web of Science (WoS) to analyze the characteristics of publications and the citations they received. Results: 1,086 published articles used data from BioLINCC repository for 79 (40.72%) datasets, where 115 (59.28%) datasets didn’t have any publications associated with it. Of the total publications, 987 (90.88%) articles were WoS indexed. The number of publications has steadily increased since 2002 and peaked in 2018 with a total number of 138 publications on that year. The 987 open data publications received a total of 34,181 citations up to 1st October 2019. The average citation per item for the open data publications was 34.63. The total number of citations received by open data publications per year has increased from only 2 citations in 2002, peaking in 2018 with 2361 citations. Conclusion: Majority of BioLINCC datasets were not used in secondary publications. Despite that, the datasets used for secondary publications yielded publications in WoS indexed journals and are receiving an increasing number of citations.

Der lombardische Rhythmus im "Domine Deus" der h-Moll-Messe J. S. Bachs
Authors: Herz Gerhard 
Published: September 2020

Die Entdeckung von zwei bisher unbeobachteten Tönen in der autografen zweiten Geige und den Bratschenstimmen des "Domine Deus" aus der h-Moll-Messe BWV 232, die von Bach in umgekehrtem punktiertem Rhythmus notiert wurden, löst die alte Kontroverse über die rhythmische Ausführung. Die strategische Lage dieser beiden Takte und die seit langem bekannten "lombardischen" Takte im der autografen Flötenstimme machen die Einwände hinfällig, die gegen die lombardische Ausführung erhoben wurden, weil sie in der ersten Violinstimme fehlt. Weitere Beispiele zeigen, dass der lombardische Rhythmus ein Teil von Bachs Kompositionsstil in den frühen 1730er Jahren war. Er war jedoch keine plötzliche Modeerscheinung, da Bach diesen Rhythmus in späteren Parodien und Wiederholungen beibehielt. Da die von Bach an den lombardischen Rhythmus angelehnten Texte weitgehend verwandt sind, können wir weiter von einer Affinität des Affekts sprechen.

Bachs Violinkonzert d-Moll. Studien zu seiner Gestalt und seiner Entstehungsgeschichte.
Authors: Breig Werner 
Published: September 2020

Das Violinkonzert in d-Moll, für das keine originale Quelle erhalten ist, kann aus Bachs Transkriptionen in BWV 146, 188 und 1052 sowie aus C. P. E. Bachs Transkription BWV 1052a erschlossen werden. Aus der Diskussion textlicher Probleme ergeben sich einige Vorschläge für Abweichungen von der Rekonstruktion in NBA VII/7. Die Untersuchung der Autorschaft zeigt, dass die anderen Sätze wahrscheinlich auf einem früheren Violinkonzert basieren, während der Mittelsatz keine Nachbearbeitung zu sein scheint. Das Violinkonzert stammt vermutlich aus Bachs Köthener Zeit. Bach fügte offenbar zu den äußeren Sätzen, die nicht von ihm komponiert wurden, einen neuen Mittelsatz hinzu.

P. C. Stolle (1706-1779/80), Leipziger Alumnus der Thomasschule von 1722 bis 1733, bat 1734 Bach um ein Zeugnis. Dieses Dokument befindet sich im Staatsarchiv Weimar. Aus Bachs vorsichtiger Formulierung lässt sich ableiten, dass Stolles musikalisches Können begrenzt war. (Übertragung des englischen Resümees am Ende des Bandes)

Eine unbekannte Wiederaufführung der Kantate "Mein Herze schwimmt im Blut" BWV 199/BC A 120
Authors: Wollny Peter 
Published: September 2020

Angesichts der großen Zahl von Aufführungsbelegen für BWV 199 in Bachs Weimarer, Köthener und frühen Leipziger Zeit nimmt es Wunder, dass ähnliche Hinweise zur Geschichte des Werkes in den späteren Leipziger Jahren und auch nach 1750 rar gesät sind. Dazu finden sich Hinweise auf einen bislang nicht näher nachvollziehbaren Überlieferungsweg der Originalquellen zu BWV 199, die der Beitrag nachzuzeichnen versucht. Dazu dient besonders ein bis dato unbeachtet gebliebener Textdruck zu einer am 5. 2. 1747 in Halle aufgeführten Trauerkantate für Johann Georg Francke, der im Wesentlichen das Libretto der Bach-Kantate zur Grundlage hat.
