Are vertical jump height and power output correlated to physical performance in different sports? An allometric approach
Authors: Pupo Juliano Dal , Ache-Dias Jonathan , Kons Rafael Lima , Detanico Daniele 
Published: January 2021

PurposeThis study aimed to analyse the relationship between vertical jump parameters – jump height (JH), peak power
output (PPO), and mean power output (MPO) – and specific physical performance in different sports using the allometric
approach. In this sense, it was verified whether scaled power output for body mass might have a stronger correlation with
physical performance than raw power output.MethodsThe study involved 52 male athletes (21 judokas, 18 futsal players, and 13 sprint runners). They performed the
following tests: vertical jumps (countermovement and squat), specific physical tests for judo (Special Judo Fitness Test),
repeated sprint ability for futsal players, and sprint running (20 m and 200 m) for runners. A specific allometric exponent
for PPO and MPO was established. Pearson’s correlation was used to determine the relationship between physical tests
and vertical jump parameters for absolute and allometric scales.ResultsModerate to very large correlations were found between physical performance and JH (<i>r</i>: 0.47–0.87), PPO (<i>r</i>: 0.47–0.75),
and MPO (<i>r</i>: 0.49–0.81). Considering power output scaled for body mass, the correlation between jump parameters and
physical performance was greater than absolute values, in which the r values ranged 0.46–0.81 for PPO and 0.52–0.84 for MPO.ConclusionsJH and power output seem to correlate in a similar magnitude with physical performance tests for most
variables and sports analysed. From a practical point of view, coaches and physical trainers are encouraged to use JH to
monitor training, considering the cost of equipment and practicality.

Published: January 2021

BackgroundType 2 diabetes mellitus (DMT2) is frequently associated with complications that can lead to lower limb ampu-tation, being the second major cause of amputation. The amputee becomes dependent on caregivers, who are often unprepared for this new role and face many challenges. Caregiving influences several dimensions of the caregiver’s life. This study evaluates the mediating role of traumatic stress in the relationship between caregiv-er perceived stress and burden/quality of life (QoL) taking also into consideration the duration of caregiving and whether the caregiver receives help in caregiving tasks, in informal caregivers of amputees due to diabetic foot over a 10 month period.Participants and procedureThe sample consisted of 110 informal caregivers of amputees due to diabetic foot with type 2 diabetes. This longitudinal study evaluates, at three time points, the mediating role of traumatic stress in the relationship be-tween perceived stress and burden/quality of life considering the duration of caregiving and whether the care-giver received help and social support in caregiving tasks.ResultsThe results showed that the duration of caregiving, help in caregiving and caregiver stress (T1) predicted trau-matic stress seven months (T2) after patients’ amputation; and traumatic stress (T2) predicted mental QoL and burden, 10 months later (T3).ConclusionsThis study emphasizes the importance of intervention in caregivers at the beginning of caregiving, to improve mental QoL and decrease the burden, ten months after amputation.

Authors: Kolesovs Aleksandrs , Ruza Aleksejs , Silkane Vineta 
Published: January 2021

BackgroundIn the time of global challenges, perception of the ongoing change at different levels of social systems modu-lates individual expectations, decisions, and emotional health. A previous study in Latvia revealed that per-ceived threats, globalization, political power, and personal control form the latent structure of perceived impacts on the country. The present study assessed the stability of this structure, comparing a relatively favorable situa-tion and the situation of the COVID-19 emergency in Latvia.Participants and procedureTwo successive independent samples included 254 and 171 university students in 2019 and 2020, respective-ly. Participants assessed the impact of 15 factors on Latvia: personal impact, parents and relatives, friends, people of Latvia, political parties and leaders, Saeima (the parliament of Latvia), the government of Latvia, the European Union, the United States, other countries, global economic crises, war and military conflicts, terror-ism, epidemics, and natural disasters.ResultsA series of confirmatory factor analyses established partial invariance of the model. During the COVID-19 emergency, a significant shift in the perceived impact of epidemics, natural disasters, and global economic crises combined with the relative stability of personal, meso-, and macro-level factors.ConclusionsThis stability indicates possible resources for balancing perceived threats in the situation of successful coping with COVID-19 in Latvia in Spring 2020.

Published: January 2021

IntroductionKnee pain is an imprecise marker of radiographic evidence of osteoarthritis (OA). These patients are more likely to develop central sensitisation to pain, a risk factor for chronic pain.ObjectivesThe aim of this study was to examine the associations among radiographic evidence of OA, self-reported pain, pressure pain thresholds (PPT), and superficial knee temperature in indivi­duals with knee OA.Material and methodsThis cross-sectional study enrolled 25 patients with knee OA with clinic and radiographic diagnosis of bilateral OA (Kellgren-Lawrence grading scale 1–4 in X-ray images), but symptoms of pain and discomfort in only one of the knees, with pain perception in the symptomatic knee equal to or above 4 in a visual analogue scale. Volunteers underwent an evaluation including demographic data, superficial knee temperature (infrared thermography, mean superficial temperature of the region of the knee) and PPT (digital algometry at longus adductor, vastus lateralis, vastus medialis and tibialis anterior muscles, patellar tendon, and centre of the patella).ResultsComparisons between symptomatic and asymptomatic knees revealed no differences regarding Kellgren-Lawrence classification, knee superficial temperature, or PPT. Significant weak and moderate associations were found between radiographic classification of OA and PPT of both knees in almost all sites evaluated. Nonetheless, superficial temperature of the knee was not associated with PPT or Kellgren-Lawrence grading scale.

Published: January 2021

IntroductionIn 1979, Bird et al. proposed depression as a diagnostic criterion for polymyalgia rheumatica (PMR). More recently, the significance of depression in PMR patients has been re-proposed, , and some researchers have suggested that PMR may increase the risk of depression. The aim of our article is to evaluate the relationship between PMR and depression.Material and methodsSystematic literature searches were performed on 19th and 20th May 2020 based on Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The search was restricted to all studies and case reports with English abstract, published in any language, since 1979 (when depression was first proposed as a diagnostic criterion for PMR) describing the association of PMR with depression. Exclusion criteria were as follows: reviews, conference abstracts, comments, non-original articles; and articles discussing giant cell arteritis (GCA) and PMR when data and observations for the two conditions were not clearly subdivided.ResultsThe initial search yielded 812 papers, of which 115 duplicates were removed. A total of 697 articles had a first screening and 506 were excluded based on title and abstract reviews; 117 articles underwent full-length scrutiny, and 99 full-text articles were excluded because they did not meet the inclusion and exclusion criteria (reviews and comments = 58; articles with outcome of interest not reported = 34; low-quality articles = 7). At least, 18 articles were included in this review.ConclusionsThe review did not find any studies that clarified the prevalence rates of depression in patients with PMR. Furthermore, the studies reviewed did not offer any clarity as to whether patients suffered from just depressive symptoms or clinical depression, and that accepted diagnostic criteria for depression had not been employed, indicating that a robust method for diagnosing depression had not been employed. Collaboration of different professionals should be improved through shared guidelines.
Southern Ocean Biogeochemical Argo detect under-ice phytoplankton growth before sea ice retreat
Authors: Hague Mark , Vichi Marcello 
Published: January 2021

Abstract. The seasonality of sea ice in the Southern Ocean has profound effects on the life cycle (phenology) of phytoplankton residing under the ice. The current literature investigating this relationship is primarily based on remote sensing, which often lacks data for half of the year or more. One prominent hypothesis holds that, following ice retreat in spring, buoyant meltwaters enhance available irradiance, triggering a bloom which follows the ice edge. However, an analysis of Biogeochemical Argo (BGC-Argo) data sampling under Antarctic sea ice suggests that this is not necessarily the case. Rather than precipitating rapid accumulation, we show that meltwaters enhance growth in an already highly active phytoplankton population. Blooms observed in the wake of the receding ice edge can then be understood as the emergence of a growth process that started earlier under sea ice. Indeed, we estimate that growth initiation occurs, on average, 4–5 weeks before ice retreat, typically starting in August and September. Novel techniques using on-board data to detect the timing of ice melt were used. Furthermore, such growth is shown to occur under conditions of substantial ice cover (>90 % satellite ice concentration) and deep mixed layers (>100 m), conditions previously thought to be inimical to growth. This led to the development of several box model experiments (with varying vertical depth) in which we sought to investigate the mechanisms responsible for such early growth. The results of these experiments suggest that a combination of higher light transfer (penetration) through sea ice cover and extreme low light adaptation by phytoplankton can account for the observed phenology.

Published: January 2021

Abstract. Ocean gliders can provide high-spatial- and temporal-resolution data and target specific ocean regions at a low cost compared to ship-based measurements. An important gap, however, given the need for carbon measurements, is the lack of capable sensors for glider-based CO2 measurements. We need to develop robust methods to evaluate novel CO2 sensors for gliders. Here we present results from testing the performance of a novel CO2 optode sensor (Atamanchuk et al., 2014), deployed on a Slocum glider, in the Labrador Sea and on the Newfoundland Shelf. This paper (1) investigates the performance of the CO2 optode on two glider deployments, (2) demonstrates the utility of using the autonomous SeaCycler profiler mooring (Send et al., 2013; Atamanchuk et al., 2020) to improve in situ sensor data, and (3) presents data from moored and mobile platforms to resolve fine scales of temporal and spatial variability of O2 and pCO2 in the Labrador Sea. The Aanderaa CO2 optode is an early prototype sensor that has not undergone rigorous testing on a glider but is compact and uses little power. Our analysis shows that the sensor suffers from instability and slow response times (τ95>100 s), affected by different behavior when profiling through small (<3 ∘C) vs. large (>10 ∘C) changes in temperature over similar time intervals. We compare the glider and SeaCycler O2 and CO2 observations and estimate the glider data uncertainty as ± 6.14 and ± 44.01 µatm, respectively. From the Labrador Sea mission, we point to short timescales (<7 d) and distance (<15 km) scales as important drivers of change in this region.

OBJECTIVESIn the inpatient psychiatric setting, one treatment strategy used to manage acute agitation in youth includes administration of IM antipsychotics. The aim of this study was to compare the effectiveness and safety of IM chlorpromazine versus IM olanzapine in treating aggression in youth.METHODSWe conducted a retrospective chart review of patients younger than 18 years hospitalized in the inpatient psychiatric unit who received either IM chlorpromazine or IM olanzapine for acute agitation. Demographic, efficacy, and tolerability data were collected using the electronic health record EPIC. The primary outcome was change from baseline to end point in the Behavioral Activity Rating Scale (BARS) score. BARS was applied retrospectively using nursing and physician documentation to evaluate for clinical response.RESULTSAmong 145 patients who met the inclusion criteria, 72 received IM chlorpromazine, compared with 73 who received IM olanzapine. The mean change in BARS score (before and after IM antipsychotic) was greater with olanzapine (3.58 ± 0.99) than with chlorpromazine (3.07 ± 1.18, p = 0.006). The target BARS score of 4 was achieved more frequently with chlorpromazine (45.8%) than with olanzapine (24.7%, p &lt; 0.008). Coadministration of IM diphenhydramine occurred significantly more often in the olanzapine group than in the chlorpromazine group (71.2% vs 36.1%, p &lt; 0.001).CONCLUSIONSManagement of acute agitation with IM olanzapine resulted in a greater change in BARS score, despite more youth requiring coadministration with diphenhydramine. In comparison, IM chlorpromazine demonstrated a higher likelihood of returning patients to baseline. Study results suggest tolerability of IM chlorpromazine and olanzapine.

OBJECTIVEKetamine is commonly used as an anesthetic and analgesic agent for procedural sedation, but there is little evidence on its current use as a prolonged continuous infusion in the PICU. We sought to analyze the use of ketamine as a prolonged infusion in critically ill children, its indications, dosages, efficacy, and safety.METHODSWe retrospectively reviewed the clinical charts of patients receiving ketamine for ≥24 hours in the period 2017–2018 in our tertiary care center. Data on concomitant treatments pre and 24 hours post ketamine introduction and adverse events were also collected.RESULTSOf the 60 patients included, 78% received ketamine as an adjuvant of analgosedation, 18% as an adjuvant of bronchospasm therapy, and 4% as an antiepileptic treatment. The median infusion duration was 103 hours (interquartile range [IQR], 58–159; range, 24–287), with median dosages between 15 (IQR, 10–20; range, 5–47) and 30 (IQR, 20–50; range, 10–100) mcg/kg/min. At 24 hours of ketamine infusion, dosages/kg/hr of opioids significantly decreased (p &lt; 0.001), and 81% of patients had no increases in dosages of concomitant analgosedation. For 27% of patients with bronchospasm, the salbutamol infusions were lowered at 24 hours after ketamine introduction. Electroencephalograms of epileptic patients (n = 2) showed resolution of status epilepticus after ketamine administration. Adverse events most likely related to ketamine were hypertension (n = 1), hypersalivation (n = 1), and delirium (n = 1).CONCLUSIONSKetamine can be considered a worthy strategy for the analgosedation of difficult-to-sedate patients. Its use for prolonged sedation allows the sparing of opioids. Its efficacy in patients with bronchospasm or status epilepticus still needs to be investigated.
Memórias ao sol: em busca de uma dramaturgia da escuta com mulheres em privação de liberdade

Published: January 2021

No presente artigo analisa-se um processo artístico-pedagógico com mulheres em situação de cárcere em 2019 no Presídio Feminino de Florianópolis, em Santa Catarina. Compreende-se que uma das estratégias da prisão é a invisibilização das pessoas a ela submetidas, sendo que suas histórias são construídas por outros e, mesmo alicerçadas em estigmas, procurou-se ir na contramão desses processos. Assim, as proposições da oficina tiveram como foco o desenvolvimento de práticas que convocassem uma reapropriação e ressignificação das histórias de vida, a partir do terreno do teatro. Buscou-se, a partir da escuta dos materiais gerados e do próprio processo, a construção de uma escrita que não omitisse as vozes das mulheres que fizeram a oficina, mas que, pelo contrário, colocasse-as em foco.

Riesgo en la información financiera en el contexto del nuevo informe de auditoría en España.
Tras la crisis financiera y debido a la mayor complejidad de la información financiera, los grupos de interés de las empresas solicitaban un informe de auditoría más completo para reducir el gap de expectativas de la auditoría. En este contexto, el Consejo Internacional de Normas de Auditoría y Aseguramiento (IAASB) aprobó una nueva norma internacional sobre los informes de auditoría. Uno de los principales cambios es la obligación de las empresas que cotizan en bolsa de describir en el informe de auditoría las cuestiones clave de auditoría (KAMs), en particular, las relacionadas con los riesgos significativos de la información financiera. Este artículo analiza empíricamente el contenido del nuevo informe de auditoría tras la reforma contable recientemente aprobada en España y los factores que condicionan los KAMs desglosados por el auditor. Utilizando la totalidad de la muestra de empresas españolas que cotizan en bolsa, nuestros resultados indican que estas firmas presentan en su mayoría entre dos y cuatro KAMs y que casi la totalidad incluyen el reconocimiento de ingresos, el deterioro del fondo de comercio y la recuperación de impuestos diferidos en los informes de auditoría del año 2017. Aplicando una regresión lineal multinomial, las variables significativas que condicionan los KAMs en nuestra muestra son el sector, el tipo de mercado y el número medio de palabras por KAM. Esta evidencia contribuye a la literatura al enfatizar la importancia de los riesgos sobre la información financiera en el informe ampliado de auditoría.
After the financial crisis and with the greater complexity of financial reporting, stakeholders asked firms for more informative audit reports to close the audit expectation gap. In this context, the International Auditing and Assurance Standards Board (IAASB) approved a new international standard on auditor’s reports. One of the major changes is the obligation for listed companies to describe the key audit matters (KAM) in the audit report, in particular, those related to the significant financial reporting risks. This paper empirically analyses the content of the new auditor’s reports after the accounting reform recently issued in Spain and the factors that condition the KAMs disclosed by auditors. Using the sample of all Spanish listed companies, our results show that these firms mostly report on two to four KAMs and the majority of these relate to revenue recognition, impairment of goodwill and deferred tax recovery in the 2017 audit reports. Applying a multinomial linear regression, the significant variables that condition the KAMs in our sample are sector, market type, and average word count. This evidence contributes to the literature by emphasizing the importance of risks in financial reporting in extended audit reports.

AbstractSprague–Dawley male rats, fed with a tryptophan‐deficient and 8% protein corn‐based diet were compared with a group of animals fed with 8% protein alone, and with a group fed with Chow Purina containing 23% protein. Retardation of Bergmann glial cell maturation and a concomitant retardation in granule cell migration were observed in the corn‐fed group at 21 days. At 30 days of age, the dendrites of granule cells of both hypoproteic and corn‐fed groups were larger than those of the Chow‐fed animals. At 60 days of age, dendritic arborization of Purkinje cells was more profuse in both the hypoproteic and corn‐fed rats compared with the Chow‐fed group. This retardation in granule cell migration could be partially due to Bergmann glial cell immaturity. Consequently, several plastic and maybe compensatory events in both granule and Purkinje cells could have occurred, due to tryptophan deficiency resulting from the corn‐based diet.

Published: July 2002

SummaryWe investigated research activities on schizophrenia in 17 non-English speaking (13 European: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Italy, Luxembourg, Netherlands, Portugal, Spain, and Sweden and 4 Asian: China, Japan, South Korea, and Taiwan) countries via a MEDLINE database survey. Despite the handicap of language, a reassuringly large number of English-written papers in research into schizophrenia have been reported; 892 papers from these countries appeared over the period 1990–1994. Among the countries investigated, Scandinavian countries in particular were found to have produced more communicable papers after taking into account the number of psychiatrists.
