Three-Dimensional Kinematics of the Overarm Throwing Motion in Children Ages 2 to 7
Background and Purpose: Throwing is a meaningful play activity that encourages social interaction, develops the sequencing of motor skills, and signals the onset of toddlerhood. Little published data clearly documents the three-dimensional kinematics of the progression of the overarm throwing motion in children. The purpose of this study is twofold: 1) To explore the biomechanical differences in the overarm throwing techniques of children between the ages of two and seven, and 2) To compare the kinematics of dominant versus non-dominant arm throws in children between the ages of two and seven.
Methods: 1) Nine children, 6 males and 3 females, were classified into 3 age groups (2-3 years, 4-5 years, 6-7 years) and then videotaped while performing 6 overarm throws, 3 with each arm. 2) The Peak Motus Software was used to digitize and analyze the reflective markers on the resultant video and create data sets for each child. Five variables were analyzed: type of throw, time of throw, ball velocity, maximum shoulder abduction, and elbow flexion at release.
Results: 1) Older children consistently used the more mature \u27dynamic\u27 and \u27sequentially-linked\u27 throwing techniques, while the younger children were variable in their approaches. 2) The 6-7 year-olds took the longest time to throw and had the greatest time difference between arms (0.23 sec.) 3) Ball velocity increased with age, with the greatest mean difference between arms (2.68 mls) occurring in the 6-7 year-olds. 4) The same group also averaged the largest amount of shoulder abduction (dominant = 60.8o/non-dominant = 70.9°). 5) The 4-5 year-olds demonstrated the greatest amount of elbow flexion at release, and the largest mean difference (8.6°) between arms.
Conclusion: Overall, children use a wide variety of throwing techniques when completing an overarm throw. There is a tendency for an increase in biomechanical differences between arms as the child ages. In general, this differentiation of arms, into dominant and non-dominant, begins to affect the quality of throw in children between the ages of 5 and 6. More studies are needed with a larger number of subjects and equal sample sizes to obtain statistically significant results
Understanding and Negotiating Book Publication Contracts
Authors are sometimes so grateful to get a publication offer that they may be tempted to sign the first version of a publication contract that they receive, especially if negotiating seems complicated, intimidating, or risky. But there is a lot at stake for authors in a book deal, and it is well worth the effort to read the contract, understand its contents, and negotiate for favorable terms. A publication contract outlines what rights you are granting to your publisher and on what terms. If you sign away all of the rights in your book to the publisher for the life of copyright, this will preclude you from certain future uses of your work. Even if you don’t have any future plans for your work, you may still regret transferring all rights if your publisher does not make full use of them, your book falls out of print, or sales drop. The terms of the contract can also dictate the specifics of how you will be paid for your book, how much input you have in the appearance of your book, your commitments relating to the manuscript and future works, who is responsible for legal claims stemming from your book’s content, how your book will be promoted, whether and how you can regain control over the rights to your book, and much more. Understanding and Negotiating Book Publication Contracts identifies clauses that frequently appear in publishing contracts, explains in plain language what these terms (and typical variations) mean, and presents strategies for negotiating “author-friendly” versions of these clauses. When authors have more information about copyright and publication options for their works, they are better able to make and keep their works available in the ways they want

Stimulation of the tibial nerve: a protocol for a multicentred randomised controlled trial for urinary problems associated with Parkinson’s disease—STARTUP
Introduction Parkinson’s disease is the second most common chronic neurodegenerative condition with bladder dysfunction affecting up to 71%. Symptoms affect quality of life and include urgency, frequency, hesitancy, nocturia and incontinence. Addressing urinary dysfunction is one of the top 10 priority research areas identified by the James Lind Alliance and Parkinson’s UK. Objectives Conduct a randomised controlled trial (RCT) targeting people with Parkinson’s disease (PwP) who have self-reported problematic lower urinary tract symptoms, investigating the effectiveness of transcutaneous tibial nerve stimulation (TTNS) compared with sham TTNS. Implement a standardised training approach and package for the correct application of TTNS. Conduct a cost-effectiveness analysis of TTNS compared with sham TTNS. Methods and analysis An RCT of 6 weeks with twice weekly TTNS or sham TTNS. Participants will be recruited in 12 National Health Service neurology/movement disorder services, using a web-based randomisation system, and will be shown how to apply TTNS or sham TTNS. Participants will receive a weekly telephone call from the researchers during the intervention period. The trial has two coprimary outcome measures: International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form and the International Prostate Symptom Score. Secondary outcomes include a 3-day bladder diary, quality of life, acceptability and fidelity and health economic evaluation. Outcomes will be measured at 0, 6 and 12 weeks. A sample size of 208 randomised in equal numbers to the two arms will provide 90% power to detect a clinically important difference of 2.52 points on the Internatioanl Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) and of 3 points in the International Prostate Symptom Score total score at 12 weeks at 5% significance level, based on an SD of 4.7 in each arm and 20% attrition at 6 weeks. Analysis will be by intention to treat and pre defined in a statistical analysis plan Ethics and dissemination East of Scotland Research Ethics Service (EoSRES), 18/ES00042, obtained on 10 May 2018. The trial will allow us to determine effectiveness, safety, cost and acceptability of TTNS for bladder dysfunction in PWP. Results will be published in open access journals; lay reports will be posted to all participants and presented at conferences. Trial registration number ISRCTN12437878; Pre-results
Factors affecting continuation of clean intermittent catheterisation in people with multiple sclerosis: results of the COSMOS mixed-methods study
Background: Clean intermittent catheterisation (CIC) is often recommended for people with multiple sclerosis (MS). Objective: To determine the variables that affect continuation or discontinuation of the use of CIC. Methods: A three-part mixed-method study (prospective longitudinal cohort (n = 56), longitudinal qualitative interviews (n = 20) and retrospective survey (n = 456)) was undertaken, which identified the variables that influenced CIC continuation/discontinuation. The potential explanatory variables investigated in each study were the individual’s age, gender, social circumstances, number of urinary tract infections, bladder symptoms, presence of co-morbidity, stage of multiple sclerosis and years since diagnosis, as well as CIC teaching method and intensity. Results: For some people with MS the prospect of undertaking CIC is difficult and may take a period of time to accept before beginning the process of using CIC. Ongoing support from clinicians, support at home and a perceived improvement in symptoms such as nocturia were positive predictors of continuation. In many cases, the development of a urinary tract infection during the early stages of CIC use had a significant detrimental impact on continuation. Conclusion: Procedures for reducing the incidence of urinary tract infection during the learning period (i.e. when being taught and becoming competent) should be considered, as well as the development of a tool to aid identification of a person’s readiness to try CIC
A multi-institutional study evaluating and describing atypical parathyroid tumors discovered after parathyroidectomy
Objective: To describe common intraoperative and pathologic findings of atypical parathyroid tumors (APTs) and evaluate clinical outcomes in patients undergoing parathyroidectomy.
Methods: In this multi-institutional retrospective case series, data were collected from patients who underwent parathyroidectomy from 2000 to 2018 from three tertiary care institutions. APTs were defined according to the AJCC eighth edition guidelines and retrospective chart review was performed to evaluate the incidence of recurrent laryngeal nerve injury, recurrence of disease, and disease-specific mortality.
Results: Twenty-eight patients were identified with a histopathologic diagnosis of atypical tumor. Mean age was 56 years (range, 23-83) and 68% (19/28) were female. All patients had an initial diagnosis of primary hyperparathyroidism with 21% (6/28) exhibiting clinical loss of bone density and 32% (9/28) presenting with nephrolithiasis or renal dysfunction. Intraoperatively, 29% (8/28) required thyroid lobectomy, 29% (8/28) had gross adherence to adjacent structures and 46% (13/28) had RLN adherence. The most common pathologic finding was fibrosis 46% (13/28). Postoperative complications include RLN paresis/paralysis in 14% (4/28) and hungry bone syndrome in 7% (2/28). No patients with a diagnosis of atypical tumor developed recurrent disease, however there was one patient that had persistent disease and hypercalcemia that is being observed. There were 96% (27/28) patients alive at last follow-up, with one death unrelated to disease.
Conclusion: Despite the new AJCC categorization of atypical tumors staged as Tis, we observed no recurrence of disease after resection and no disease-specific mortality. However, patients with atypical tumors may be at increased risk for recurrent laryngeal nerve injury and incomplete resection
Kinetics and Identities of Extracellular Peptidases in Subsurface Sediments of the White Oak River Estuary, North Carolina
Anoxic subsurface sediments contain communities of heterotrophic microorganisms that metabolize organic carbon at extraordinarily low rates. In order to assess the mechanisms by which subsurface microorganisms access detrital sedimentary organic matter, we measured kinetics of a range of extracellular peptidases in anoxic sediments of the White Oak River Estuary, NC. Nine distinct peptidase substrates were enzymatically hydrolyzed at all depths. Potential peptidase activities (Vmax) decreased with increasing sediment depth, although Vmax expressed on a per-cell basis was approximately the same at all depths. Half-saturation constants (Km) decreased with depth, indicating peptidases that functioned more efficiently at low substrate concentrations. Potential activities of extracellular peptidases acting on molecules that are enriched in degraded organic matter (d-phenylalanine and l-ornithine) increased relative to enzymes that act on l-phenylalanine, further suggesting microbial community adaptation to access degraded organic matter. Nineteen classes of predicted, exported peptidases were identified in genomic data from the same site, of which genes for class C25 (gingipain-like) peptidases represented more than 40% at each depth. Methionine aminopeptidases, zinc carboxypeptidases, and class S24-like peptidases, which are involved in single-stranded-DNA repair, were also abundant. These results suggest a subsurface heterotrophic microbial community that primarily accesses low-quality detrital organic matter via a diverse suite of well-adapted extracellular enzymes.
IMPORTANCE Burial of organic carbon in marine and estuarine sediments represents a long-term sink for atmospheric carbon dioxide. Globally, ∼40% of organic carbon burial occurs in anoxic estuaries and deltaic systems. However, the ultimate controls on the amount of organic matter that is buried in sediments, versus oxidized into CO2, are poorly constrained. In this study, we used a combination of enzyme assays and metagenomic analysis to identify how subsurface microbial communities catalyze the first step of proteinaceous organic carbon degradation. Our results show that microbial communities in deeper sediments are adapted to access molecules characteristic of degraded organic matter, suggesting that those heterotrophs are adapted to life in the subsurface
