Authors: Karim Annette Y. , Ashmore Caleb , Burris Sara , Roddey Toni , Ortiz Alexis , Olson Sharon 
Published: January 2019

Background: Prior studies have examined muscle power via the countermovement jump (CMJ). Studies to date have examined neither the reliability nor the construct validity of the ballet first position CMJ (hips in lateral rotation, toes facing away from one another, legs straight) as a measure of power. Hypotheses: There would be (1) good interrater reliability in the visual assessment of the best-quality first position CMJ (κ ≥ 0.60), (2) good test-retest reliability in the height of the first position CMJ of good quality (intraclass correlation coefficient [ICC] ≥ 0.80), and (3) a significant relationship between isokinetic torque of the quadriceps femoris and first position CMJ height ( r ≥ 0.40). Study Design: Correlational study. Level of Evidence: Level 3. Methods: A convenience sample of 39 healthy young adults who reported moderate activity levels participated in a warm-up and 2 sessions of 6 jumps. Quadriceps femoris isokinetic torque was measured in the first session. Results: Significant agreement was found within the same day for the best-quality first position CMJ (κ = 0.81), and in the highest, best-quality first position CMJ between days (ICC2,1 = 0.88). The highest, best-quality first position CMJ, when solving for a single trial, was comparable to the average of 2 trials (single trial: ICC2,1 = 0.96 vs average of 2 trials: ICC2,k = 0.98). There was a good relationship between quadriceps femoris isokinetic strength and first position CMJ height (Pearson r = 0.69 and P < 0.001 at 60 deg/s; r = 0.64 and P < 0.001 at 180 deg/s; r = 0.65 and P < 0.001 at 300 deg/s). Conclusion: Visual video movement analysis has good to excellent interrater agreement and test-retest reliability. Selecting the single highest jump of good quality is acceptable. The first position CMJ is a measure of power. Clinical Relevance: Video analysis of the single highest first position CMJ of good quality is an acceptable method of assessing movement quality.

Published: January 2019

Background Despite a proliferation of technological advances in sinonasal surgery, “cold steel” instruments still comprise the core of the sinus surgeon’s tools of the trade. Many of these implements retain eponyms that recall the legacies of prominent surgeons of the past. Objective This review aims to familiarize the reader with the lives of 10 men who designed and popularized some of the most recognizable sinus instruments, without which the practice of rhinologic surgery would be unrecognizable. Results Ten individuals whose inventions are still used to this day and retain their names: Hartmann, Killian, Freer, Blakesley, Weil, Frazier, Grünwald, Hajek, Takahashi, and Cottle. Conclusion Review of the history of these instruments helps demonstrate how sinus surgery has evolved to where it is today. The men described in this review transformed the practice of rhinologic surgery with their ingenuity and perseverance.

Published: January 2019

Purpose Due to a suggestive three-way relationship between brain structural disorders, microvascular lesions, and cognitive impairments, we aimed to examine the association of the volume and number of white matter hyperintensity lesions and lacunar infarcts with cognitive impairment among patients with cardiovascular risk factors in a sample of the Iranian population. Materials and methods This study was conducted on a total number of 156 normal subjects aged 30–74 years with cardiovascular risk factors. We used the Framingham general cardiovascular risk factors prediction model to calculate the likelihood of each risk factor. The total number of lacunar infarcts and the volume of white matter hyperintensity lesion were calculated in brain magnetic resonance imaging. Cognition status was assessed using the Montreal Cognitive Assessment questionnaire. Results An adverse association was revealed between Montreal Cognitive Assessment score and different cardiovascular risk profiles including the Framingham body mass index score ( p < 0.001) and the Framingham lipid score ( p < 0.001). The total volume of white matter hyperintensity was negatively associated with total Montreal Cognitive Assessment cognition score ( p < 0.001). Our study also showed an adverse association between total number of lacunar infarcts and total Montreal Cognitive Assessment cognition score ( p = 0.038) and with some cognition components including memory ( p = 0.013), attention ( p = 0.037), abstraction ( p = 0.046), and orientation ( p = 0.002). Conclusion Periventricular lesions are associated with impaired memory, language, and visuoconstruction while subcortical lesions are associated with impairment in naming, attention, language, and abstraction functions in normal subjects with cardiovascular risk factors but without cardiovascular or cerebrovascular disorders.

Published: January 2019

Introduction: Posterior tibialis tendon insufficiency is the most common cause of adult acquired flatfoot deformity in elderly patients. We performed a literature search of primary and secondary journal articles pertaining to posterior tibialis tendon insufficiency in the geriatric population. We examined relevant data from these articles regarding current evaluation in addition to both conservative and advanced treatment approaches that correspond to disease severity. Significance: There is a paucity of literature to guide treatment of posterior tibialis tendon insufficiency in the elderly, and this condition may be more prevalent in geriatric patients than previously realized. Results: Posterior tibialis tendon insufficiency is an acquired defect that affects 10% of the geriatric population and disproportionately affects women. It is typically caused by degenerative changes. There are four primary stages of posterior tibialis tendon with subcategorizations that range from mild to severe. Conservative treatment with a variety of available ankle braces and non-steroidal anti-inflammatory medications are typically used to treat the first and second stage disease. Surgical repair is warranted for advanced second stage and above posterior tendon insufficiency. A variety of techniques have been proposed, and can include tendon transfer, hindfoot fusion, and even total ankle arthroplasty in extreme cases. Conclusion: Posterior tibialis tendon insufficiency causes marked discomfort and alters normal gait biomechanics. Elderly patients typically present with more severe manifestations of the disease. For patients requiring surgery, and especially geriatric patients, the ideal treatment is thought to be a procedure that is minimally invasive in order to maximize positive outcomes for elderly patients. More work is needed to examine clinical and radiographic outcomes of geriatric patients treated for posterior tibialis tendon insufficiency.

Published: January 2019

Background: Arthroscopic posterior shoulder stabilization can be performed with patients in the beach-chair (BC) and the lateral decubitus (LD) positions; however, the impact of patient positioning on clinical outcomes has not been evaluated. Purpose: To compare clinical outcomes and recurrence rates after arthroscopic posterior shoulder stabilization performed in the BC and LD positions. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review using PRISMA (Preferred Reporting Items for Systematic Meta-Analyses) guidelines was performed by searching PubMed, Embase, and the Cochrane Library for studies reporting the clinical outcomes of patients undergoing arthroscopic posterior shoulder stabilization in either the BC or LD position. All English-language studies from 1990 to 2017 reporting clinical outcomes after arthroscopic posterior shoulder stabilization with a minimum 2-year follow-up were reviewed by 2 independent reviewers. Data on the recurrent instability rate, return to activity or sport, range of motion, and patient-reported outcome scores were collected. Study methodological quality was evaluated using the Modified Coleman Methodology Score (MCMS) and Quality Appraisal Tool (QAT). Results: A total of 15 studies (11 LD, 4 BC) with 731 shoulders met the inclusion criteria, including 626 shoulders in the LD position (mean patient age, 23.9 ± 4.1 years; mean follow-up, 37.5 ± 10.0 months) and 105 shoulders in the BC position (mean patient age, 27.8 ± 2.2 years; mean follow-up, 37.9 ± 16.6 months). There was no significant difference in the overall mean recurrent instability rate between the LD and BC groups (4.9% ± 3.6% vs 4.4% ± 5.1%, respectively; P = .83), with similar results in a subanalysis of studies utilizing only suture anchor fixation (4.9% ± 3.6% vs 3.2% ± 5.6%, respectively; P = .54). There was no significant difference in the return-to-sport rate between the BC and LD groups (96.2% ± 5.4% vs 88.6% ± 9.1%, respectively; P = .30). Range of motion and other patient-reported outcome scores were not provided consistently across studies to allow for statistical comparisons. Conclusion: Low rates of recurrent shoulder instability and high rates of return to sport can be achieved after arthroscopic posterior shoulder stabilization in either the LD or the BC position. Additional long-term randomized trials comparing these positions are needed to better understand the potential advantages and disadvantages of surgical positioning for posterior shoulder stabilization.

Published: January 2019

IntroductionDynamic hyperinflation has been documented in asthma, yet its impact on overall health and daily life activities is unclear. We assessed the prevalence of dynamic hyperinflation in moderate to severe asthma and its relationship with the scores of a set of specific and general respiratory health questionnaires.Methods77 nonsmoking asthma patients (Global Initiative for Asthma steps 4–5) were recruited consecutively and completed five questionnaires: Asthma Control Questionnaire, Clinical COPD (chronic obstructive pulmonary disease) Questionnaire, St George's Respiratory Questionnaire, London Chest Activity of Daily Living scale (LCADL) and Shortness of Breath with Daily Activities (SOBDA). Dynamic hyperinflation was defined as ≥10% reduction in inspiratory capacity induced by standardised metronome-paced tachypnoea. Associations between level of dynamic hyperinflation and questionnaire scores were assessed and adjusted for asthma severity.Results81% (95% CI 71.7–89.4%) of patients showed dynamic hyperinflation. Higher levels of dynamic hyperinflation were related to poorer scores on all questionnaires (r=0.228–0.385, p<0.05). After adjustment for asthma severity, dynamic hyperinflation remained associated with poorer scores on LCADL (p=0.027) and SOBDA (p=0.031).ConclusionDynamic hyperinflation is associated with poorer overall health and impaired daily life activities, independent of asthma severity. Because of its major impact on everyday life activities, dynamic hyperinflation is an important target for treatment in asthma.

Published: January 2019

Background:Palliative care (PC) workforce shortages have led to a need for primary PC provided by non-specialists. The Care Management by Oncology Nurses (CONNECT) intervention provides infusion room oncology nurses with training and support to provide primary PC.Aims:To describe nurses' perspectives on the personal and professional impact of training and provision of primary PC as part of CONNECT.Methods:This qualitative study consisted of in-depth telephone interviews with 11 nurses at oncology practices in Pennsylvania. Data was analysed using qualitative content analysis.Findings:Nurses reported a sense of personal and professional fulfillment from providing primary PC, while noting the risk of increased emotional attachment to patients. Participation improved nursing communication skills. A supportive workplace helped to minimise stress related to incorporating primary PC into busy treatment schedules.Conclusion:Providing primary PC challenges the task-oriented paradigm of nursing practice and will potentially alter the professional roles and workloads of infusion room nurses.

Zusammenfassung
Bei Hyperthermiebehandlungen ist eine ortsaufgelöste Temperaturüberwachung für eine erfolgreiche Krebstherapie notwendig. Dieser Beitrag stellt ein Verfahren vor, das es erlaubt, nicht nur relative Temperaturänderungen zu erfassen, sondern eine konkrete Zuordnung einer Temperatur zu einem Messpunkt durchzuführen. Mithilfe von Ultraschall-Annular-Arrays wird die Longitudinalwellengeschwindigkeit in Gewebephantomen gemessen. Die aufgenommenen Signale werden synthetisch fokussiert und die Signalenergie bei Variation des Fokussierungsregimes ausgewertet. Die Funktionsfähigkeit und die erreichbare Genauigkeit werden anhand modelltheoretischer Betrachtungen bestätigt. Abschließend wird die Leistungsfähigkeit des Verfahrens anhand der Überwachung eines Heizvorgangs demonstriert.
Presynaptic Diversity Revealed by Ca2+-Permeable AMPA Receptors at the Calyx of Held Synapse
Authors: Lujan Brendan , Dagostin Andre , von Gersdorff Henrique 
Published: January 2019

GluA2-lacking Ca2+-permeable AMPARs (CP-AMPARs) play integral roles in synaptic plasticity and can mediate excitotoxic cellular signaling at glutamatergic synapses. However, the developmental profile of functional CP-AMPARs at the auditory brainstem remains poorly understood. Through a combination of electrophysiological and live-cell Ca2+imaging from mice of either sex, we show that the synaptic release of glutamate from the calyx of Held nerve terminal activates CP-AMPARs in the principal cells of the medial nucleus of the trapezoid body in the brainstem. This leads to significant Ca2+influx through these receptors before the onset of hearing at postnatal day 12 (P12). Using a selective open channel blocker of CP-AMPARs, IEM-1460, we estimate that ∼80% of the AMPAR population are permeable to Ca2+at immature P4–P5 synapses. However, after the onset of hearing, Ca2+influx through these receptors was greatly reduced. We estimate that CP-AMPARs comprise approximately 40% and 33% of the AMPAR population at P18–P22 and P30–P34, respectively. By quantifying the rate of EPSC block by IEM-1460, we found an increased heterogeneity in glutamate release probability for adult-like calyces (P30–P34). Using tetraethylammonium (TEA), a presynaptic potassium channel blocker, we show that the apparent reduction of CP-AMPARs in more mature synapses is not a consequence of presynaptic action potential (AP) speeding. Finally, through postsynaptic AP recordings, we show that inhibition of CP-AMPARs reduces spike fidelity in juvenile synapses, but not in more mature synapses. We conclude that the expression of functional CP-AMPARs declines over early postnatal development in the calyx of Held synapse.SIGNIFICANCE STATEMENTThe calyx of Held synapse is pivotal to the circuitry that computes sound localization. Postsynaptic Ca2+influx via AMPARs may be critical for signaling the maturation of this brainstem synapse. The GluA4 subunit may dominate the AMPAR complex at mature synapses because of its fast gating kinetics and large unitary conductance. The expectation is that AMPARs dominated by GluA4 subunits should be highly Ca2+permeable. However, we find that Ca2+-permeable AMPAR expression declines during postnatal development. Using the rate of EPSC block by IEM-1460, an open channel blocker of Ca2+-permeable AMPARs, we propose a novel method to determine glutamate release probability and uncover an increased heterogeneity in release probability for more mature calyces of Held nerve terminals.
