RESUMEN

A multidrug-resistant strain of Klebsiella pneumoniae (Kp) sequence type (ST) 1788, an otherwise uncommon ST worldwide, was isolated from 65 patients at 11 hospitals and 11 general practices across South and West Wales, UK, between February 2019 and November 2021. A collection of 97 Kp ST1788 isolates (including 94 from Wales) was analysed to investigate the diversity and spread across Wales and to identify molecular marker(s) to aid development of a strain-specific real-time PCR. Whole genome sequencing (WGS) was performed with Illumina technology and the data were used to perform phylogenetic analyses. Pan-genome analysis of further Kp genome collections was used to identify an ST1788-specific gene target; a real-time PCR was then validated against a panel of 314 strains and 218 broth-enriched screening samples. Low genomic diversity was demonstrated amongst the 94 isolates from Wales. Evidence of spread within and across healthcare facilities was found. A yersiniabactin locus and the KL2 capsular locus were identified in 85/94 (90.4 %) and 94/94 (100 %) genomes respectively; bla SHV-232, bla TEM-1, bla CTX-M-15 and bla OXA-1 were simultaneously carried by 86/94 (91.5 %) isolates; 4/94 (4.3 %) isolates also carried bla OXA-48 carbapenemase. Aminoglycoside and fluoroquinolone resistance markers were found in 94/94 (100 %) and 86/94 (91.5 %) isolates respectively. The ST1788-specific real-time PCR was 100 % sensitive and specific. Our analyses demonstrated recent clonal expansion and spread of Kp ST1788 in the community and across healthcare facilities in South and West Wales with isolates carrying well-defined antimicrobial resistance and virulence markers. An ST1788-specific marker was also identified, enabling rapid and reliable preliminary characterization of isolates by real-time PCR. This study confirms the utility of WGS in investigating novel strains and in aiding proactive implementation of molecular tools to assist infection control specialists.

RESUMEN

We describe the first case of a 62-year-old female symptomatic patient with multiple comorbidities presenting with coronal limb malalignment due to scoliosis and osteoarthritis who underwent a combined total hip arthroplasty and biplane opening wedge osteotomy of the distal femur in one procedure. It is essential to realize that in patients who present with multiple comorbidities, combining different established procedures should be considered as a therapeutic option. We detail the operative procedure, preoperative considerations, and postoperative rehabilitation. By reviewing the literature on operative techniques, we highlight how our findings can be applied to similar cases with multiple comorbidities. Our report underscores the importance of considering combined procedures as a viable therapeutic option for patients with complex medical histories.

RESUMEN

Role 1 doctors in the British Army work predominantly in primary healthcare, but also provide prehospital emergency care and administer potent parenteral medications in the field. Role 1 doctors have theoretical training in the use of these medications on short courses but then have little refresher training and use them infrequently in their routine practice, introducing the risk of skill fade. This may lead to higher rates of medication errors in an environment where the consequences may be significant. This article explores the current training of Role 1 doctors, the threat of skill fade and how the safety of drug administration can be improved. This includes recommendations for the development of training competencies, bespoke courses and clinical placements, e-learning and the use of new technology. Application of these recommendations has the potential to improve patient safety and the confidence of doctors in the use of parenteral analgesia.

RESUMEN

Despite the benefits of the internet and other digital technology, the online world has been associated with a negative impact on university student wellbeing. Many university students report symptoms of pathological internet use. Internationally, further research is needed to understand what student users of technology perceive to be problematic internet and/or digital use. The current study explores the range of perceptions that university students hold about 'digital addiction'. We recruited 33 participants from a UK university into a Q-methodology study. Participants sorted, ranked, and commented on fifty-two statements representing the concourse of 'things written or said about digital addiction'. The statements were identified from a comprehensive search of a wide variety of sources (e.g., newspapers, academic articles, blogs, and YouTube). Principal Component Analysis was used to identify four distinct viewpoints of 'digital addiction': (I) digital addiction is differentiated by the negative consequences experienced by addicted individuals; (II) digital addiction comes from our fascination with the online world; (III) digital addiction is an attempt to escape real world problems and impacts on mental health and relationships; (IV) digital addiction is defined by the amount of time we spend online. All four viewpoints share the perception that people do not realize they are digitally addicted because using and having digital devices on you at all times has become the social norm. There was also overall agreement that that those with 'addictive personalities' were more likely to be 'digitally addicted'. Despite these similarities, complexity and contradictions within the viewpoints surrounding what digital addiction is and how it might be defined are apparent. The information found in this study provides important suggestions of how we might frame prevention and early intervention messages to engage students and ensure they develop the skills necessary to successfully manage their digital lives.

RESUMEN

Emmonds, S, Scantlebury, S, Murray, E, Turner, L, Robsinon, C, and Jones, B. Physical characteristics of elite youth female soccer players characterized by maturity status. J Strength Cond Res 34(8): 2321-2328, 2020-The purpose of this study was to investigate the influence of maturity status on the physical characteristics of youth female soccer players. One hundred fifty-seven players from 3 elite soccer academies in England completed assessments of anthropometry, strength (isometric midthigh pull), lower-body power (countermovement jump [CMJ]), aerobic capacity (Yo-Yo intermittent recovery test level 1), change of direction (CoD: 505-left/right), and speed (10 and 30 m). Each player was classified into 1 of 6 maturity groups based on their estimated years from peak height velocity (YPHV). Magnitude-based inferences were used to assess for the practical significance between consecutive groups. Speed, CoD time, CMJ, and aerobic capacity were all possibly most likely better in more mature players. However, there was a likely difference in relative peak force between maturity groups -0.5 YPHV (27.13 ± 4.24 N·Kg) and 0.5 YPHV (24.62 ± 3.70 N·Kg), which was associated with a likely difference in 10-m sprint time (-0.5 YPHV: 2.00 ± 0.12 vs. 0.5 YPHV 2.08 ± 0.16 seconds) and unclear changes in CMJ and CoD time. Findings provide novel comparative data for this cohort relative to maturity status and can be used by strength and conditioning coaches to inform the design of training programs for youth female soccer players. Strength and conditioning coaches should be aware that youth female soccer players may experience a decrease in relative strength around peak height velocity, which may impact upon the speed, CoD time, and CMJ of players.

RESUMEN

The title compound, C16H14FNO3, was synthesized via solid phase methods; it exhibits monoclinic (P21) symmetry at room temperature. The two independent mol-ecules that comprise the asymmetric unit display distinct torsion angles of 173.2 (2) and 72.6 (2)° along the central sp 3 C-N bond. In the crystal, hydrogen bonding through N-H⋯O contacts couples the asymmetric unit mol-ecules into pairs that align in layers extending parallel to (100) via additional O-H⋯O inter-actions. The phenyl ring of one independent mol-ecule was found to be disordered over two sets of sites in a 0.55 (3):0.45 (3) ratio.

RESUMEN

Wild sea cucumber resources have been rapidly exhausted and therefore there is an urgent need to develop approaches that will help restocking. Currently, there is a lack of information regarding the genes involved in sea cucumber reproductive processes. The neurohormone relaxin-like gonad-stimulating peptide (RGP) has been identified as the active gonad-stimulating peptide in sea stars (Asteroidea), which could also be present in other echinoderm groups. In this study, a sea cucumber RGP was identified and confirmed by phylogenetic analysis. A recombinant Holothuria scabra RGP was produced in the yeast Pichia pastoris and confirmed by mass spectrometry. To assess bioactivity, four levels of purification were tested in an in vitro germinal vesicle breakdown (GVBD) bioassay. The most pure form induced 98.56 ± 1.19% GVBD in H. scabra and 89.57 ± 1.19% GVBD in Holothuria leucospilota. Cruder levels of purification still resulted in some GVBD. Upon single injection into female H. scabra, the recombinant RGP induced head waving behavior followed by spawning within 90-170 min. Spawned oocytes were fertilized successfully, larvae settled and developed into juveniles. Our results provide a key finding for the development of a break-through new artificial breeding approach in sea cucumber aquaculture.

RESUMEN

Exercise ASKARI SERPENT (Ex AS) is an annual British Army medical exercise that sees the deployment of a medical regiment to rural Kenya. The exercise involves the delivery of health outreach clinics and health education to the civilian population alongside Kenyan governmental and non-governmental organisations. This article includes a post hoc analysis of the ethical and clinical challenges that clinicians faced during Ex AS, applying a four-quadrant approach to ethical decision-making. This article intends to stimulate further debate and discussion on how to best prepare clinicians for clinical challenges and ethical decision-making on future exercises and operations. We conclude that our experiences on Ex AS can provide an insight on how to develop predeployment training for clinicians. Furthermore, the universal nature of the challenges faced on Ex AS can be applied to training for future contingency operations.

RESUMEN

The sea cucumber (phylum Echinodermata) body wall is the first line of defense and is well known for its production of secondary metabolites; including vitamins and triterpenoid glycoside saponins that have important ecological functions and potential benefits to human health. The genes involved in the various biosynthetic pathways are unknown. To gain insight into these pathways in an echinoderm, we performed a comparative transcriptome analysis and functional annotation of the body wall and the radial nerve of the sea cucumber Holothuria scabra; to define genes associated with body wall metabolic functioning and secondary metabolite biosynthesis. We show that genes related to signal transduction mechanisms were more highly represented in the H. scabra body wall, including genes encoding enzymes involved in energy production. Eight of the core triterpenoid biosynthesis enzymes were found, however, the identity of the saponin specific biosynthetic pathway enzymes remains unknown. We confirm the body wall release of at least three different triterpenoid saponins using solid phase extraction followed by ultra-high-pressure liquid chromatography-quadrupole time of flight-mass spectrometry. The resource we have established will help to guide future research to explore secondary metabolite biosynthesis in the sea cucumber.

RESUMEN

The reaction of bismuth amides or alkoxides with phenolic ligand precursors yields Bi complexes of aminetris(phenoxide)s, one of which was characterized by X-ray crystallography, revealing monomeric Bi units of the tetradentate NO3 ligand further associated via a symmetrical toluene bridge into a bis(bismuth)toluene inverted-sandwich complex. Synthesis of the analogous Sb complex suggests a markedly different geometric and electronic environment at the metal center, as evidenced by the solid-state molecular structure. Density functional theory calculations of the sandwich bismuth arene complex indicate the presence of a weak sigma*-2pi interaction.
