Abstract	Background: Extended-spectrum β-lactamase producing Enterobacterales (ESBL-E) are important causative agents for infections in humans and animals. At the Equine Veterinary Teaching Hospital of the University of Helsinki, the first infections caused by ESBL-E were observed at the end of 2011 leading to enhanced infection surveillance. Contact patients were screened for ESBL-E by culturing infection sites and rectal screening. This study was focused on describing the epidemiology and microbiological characteristics of ESBL-E from equine patients of the EVTH during 2011-2014, and analysing putative risk factors for being positive for ESBL-E during an outbreak of Klebsiella pneumoniae ST307. Results: The number of ESBL-E isolations increased through 2012-2013 culminating in an outbreak of multi-drug resistant K. pneumoniae ST307:bla Conclusions: The occurrence of an outbreak caused by a pathogenic ESBL-producing K. pneumoniae ST307 strain highlights the importance of epidemiological surveillance of ESBL-E in veterinary hospitals. Limiting the length of hospitalisation for equine patients may reduce the risk of spread of ESBL-E. It is also important to acknowledge the importance of nasogastric tubing as a potential source of acquiring ESBL-E. As ESBL-E were also found in stomach drench pumps used with nasogastric tubes, veterinary practices should pay close attention to appropriate equipment cleaning procedures and disinfection practices.

Abstract	Abstract Background Extended-spectrum β-lactamase producing Enterobacterales (ESBL-E) are important causative agents for infections in humans and animals.

Contact patients were screened for ESBL-E by culturing infection sites and rectal screening. This study was focused on describing the epidemiology and microbiological characteristics of ESBL-E from equine patients of the EVTH during 2011–2014, and analysing putative risk factors for being positive for ESBL-E during an outbreak of Klebsiella pneumoniae ST307. Results The number of ESBL-E isolations increased through 2012–2013 culminating in an outbreak of multi-drug resistant K. pneumoniae ST307:bla CTX-M-1:bla TEM:bla SHV during 04–08/2013. During 10/2011–05/2014, altogether 139 ESBL-E isolates were found from 96 horses. Of these, 26 were from infection-site specimens and 113 from rectal-screening swabs. A total of 118 ESBL-E isolates from horses were available for further study, the most numerous being K. pneumoniae (n = 44), Escherichia coli (n = 31) and Enterobacter cloacae (n = 31). Hospital environmental specimens (N = 47) yielded six isolates of ESBL-E. Two identical E. cloacae isolates originating from an operating theatre and a recovery room had identical or highly similar PFGE fingerprint profiles as five horse isolates. In the multivariable analysis, mare–foal pairs (OR 4.71, 95% CI 1.57–14.19, P = 0.006), length of hospitalisation (OR 1.62, 95% CI 1.28–2.06, P < 0.001) and passing of a nasogastric tube (OR 2.86, 95% CI 1.03–7.95, P = 0.044) were associated with being positive for ESBL-E during the K. pneumoniae outbreak. Conclusions The occurrence of an outbreak caused by a pathogenic ESBL-producing K. pneumoniae ST307 strain highlights the importance of epidemiological surveillance of ESBL-E in veterinary hospitals. Limiting the length of hospitalisation for equine patients may reduce the risk of spread of ESBL-E. It is also important to acknowledge the importance of nasogastric tubing as a potential source of acquiring ESBL-E. As ESBL-E were also found in stomach drench pumps used with nasogastric tubes, veterinary practices should pay close attention to appropriate equipment cleaning procedures and disinfection practices.

Abstract	MtDNA sequence variation is presumed to be neutral in effect, but associations with diseases and mtDNA haplogroups have been reported. The aim here was to evaluate the functional consequences of m.4216T>C present in haplogroup J. Furthermore, we evaluated m.3866T>C in MT-ND1, a variant detected in a child belonging to haplogroup J and with an isolated complex I deficiency. Homologous substitutions were introduced into Escherichia coli. NADH dehydrogenase domain activity of NDH-1 with either one or both mutations was markedly decreased suggesting that m.4216T>C and m.3866T>C may have an effect on the structural integrity of complex I.

Abstract	The efficiency of modern tree planting machines is strongly affected by operational conditions, technical machine performance, and operator. In this study, the aim was to determine the time consumption of mechanical planting work using the M-Planter planting machine in Finnish regeneration areas where stumps were harvested and slash collected. The work of six operators, working with four M-Planter planting machines, was quantified with a stopwatch-study method. A linear mixed-effects model was used to examine the influences of operator, base machine, planting area, and work-difficulty factors on the time taken to complete planting. The quality of the planting work was also evaluated. Including a constant time for refilling seedling cassettes, the mean productivity of operators was 280 seedlings per productive work hour, and the time used to plant a seedling was on average 13.21 seconds (standard deviation 1.4 seconds). There were no significant differences in time consumption between operators; base machine did not have a significant effect on total work time; and surface obstacles was the only work-difficulty factor to slow mechanical planting work. Seedlings were planted to an acceptable quality by all operators. With respect to equipment, the M-Planter has two separate planting units, and results should not be generalized to other devices.

Abstract	This article explores the application of complexity science in sports and exercise research, introducing Ashby's law of requisite variety, Boisot's and McKelvey's law of requisite complexity, and Bar-Yam's complexity profile. These frameworks emphasize the role of complexity in system functionality and shed light on the delicate balance between complexity and scale. Utilising acroyoga as a novel research context, an interpretivist study was conducted to delve into the activity's complexity profile, revealing the intricate interplay between fostering creativity and maintaining essential regulations. Examining acroyoga practitioners' and influencers' perspectives through the complexity profile underscores the sport's complexity over scale, offering diverse physical, cognitive, affective, and social benefits. However, the limited emphasis on scaling might confine acroyoga to the fringes, hindering widespread acceptance. This study demonstrates the complexity profile as a heuristic tool, challenging assumptions and encouraging innovative perspectives. Acroyoga serves as a compelling case study, highlighting the complexity-scale balance and paving the way for further exploration and sports-related policy formulation.

Abstract	Aim: Previous studies have not described separate positive predictive values for Ortolani and Barlow tests in clinical hip screening. We aimed to determine the positive predictive values at discharge following birth, in predicting dysplasia or instability in the subsequent hip ultrasound examinations. Methods: We included all infants with suspected or diagnosed DDH at the study hospital from 2015 to 2017 in this retrospective study. Infants with positive Ortolani or Barlow test after birth were referred for a hip ultrasound, without treatment being started. The positive predictive value of the tests to predict Graf type ≥ IIC morphology, ≥5 mm displacement in a dynamic ultrasound, or either one or both findings at the hip ultrasound examination was calculated. Results: There were 33 Ortolani-positive hips and 103 Barlow-positive hips in 105 referred infants (30% male) at the screening. They received ultrasound examination at mean 21.7 days of age (SD 4.8, range 11-35). The positive predictive value was 39-61% for the Ortolani test and 4%-16% for the Barlow test depending on the true positive definition. Conclusion: The Ortolani test, performed by a specialist at the maternity ward, has a high positive predictive value for developmental dysplasia of the hip.
