Abstract
Infante, MA, Harrell, GM, Strand, KL, Parrino, RL, and Signorile, JF. One repetition maximum test-retest reliability and safety using Keiser pneumatic resistance training machines with older women. J Strength Cond Res 35(12): 3513–3517, 2021—Chest press (CP) and leg press (LP) are the most common exercises used to assess strength in older persons; therefore, the reliability of these tests is critical to clinicians and researchers. Because women comprise the highest proportion of the older population, this study examined the test-retest reliability of Keiser A420 pneumatic machines during CP and LP 1 repetition maximum (1RM) testing in 23 older women on 2 separate occasions, trial 1 (T1) and trial 2 (T2), at least 72 hours apart. Significance was set at <0.05. CP1RM and LP1RM showed excellent test-retest reliability (intraclass correlation coefficient = 0.974, 0.972, respectively, p < 0.001) and low coefficients of variation (CP1RM = 5.28%; LP1RM = 6.32%). Standard error of measurement for CP1RM (0.97 kg) was lower than that of LP1RM (6.36 kg). The minimal detectable change (MDC) for the CP1RM and LP1RM was 2.69 and 17.63 kg, respectively. Bland-Altman plots revealed only 1 point outside of the 95% CI for comparison of T1 and T2 for either exercise, there was little systematic error across average values, both lines of equality fell within the limits of agreement (LOA), and the bias between T1 and T2 for both exercises was below 5% of the average 1RM. By contrast, the LOA for CP1RM and LP1RM are somewhat wide because they both exceeded their computed MDC values. Given the excellent test-retest reliability of the Keiser A420 pneumatic CP and LP machines with older women, clinicians and researchers can confidently and safely use these machines for 1RM testing after proper familiarization.

Abstract
vonGaza, GL, and Chiu, LZF. Comparison of alternative methods to improve weight-bearing sagittal plane anterior leg rotation. J Strength Cond Res 35(12): 3315–3321, 2021—Promoting rearfoot plantar flexion may permit greater sagittal plane anterior leg rotation in weight-bearing tasks. Anterior leg rotation, where the proximal tibia translates forward, is required for tasks such as squatting and landing from a jump. Twenty-eight individuals with less than 25° anterior leg rotation during a weight-bearing lunge test were enrolled and randomly assigned to self-massage and stretching only (n = 15; 14 subjects retained) or self-massage and stretching plus gastrocnemius exercise (n = 13). Anterior leg rotation was assessed during a weight-bearing lunge test and a partial squat; 95% confidence interval (95% CI) of the change score and Cohen's d effect size were calculated. Anterior leg rotation in the weight-bearing lunge increased in the self-massage and stretching only (left: 95% CI [2.1°–5.4°], d = 1.14; right: 95% CI [2.3°–6.0°], d = 1.22) and self-massage and stretching plus gastrocnemius exercise (left: 95% CI [2.3°–7.5°], d = 1.71; right: 95% CI [4.2°–8.6°], d = 1.48) groups. There were no changes in anterior leg rotation in the partial squat for self-massage and stretching only (left: 95% CI [–1.2° to 2.5°], d = 0.15; right: 95% CI [–0.5° to 2.6°], d = 0.24) or self-massage and stretching plus gastrocnemius exercise (left: 95% CI [–0.2° to 4.8°], d = 0.55; right: 95% CI [–0.2° to 4.0°], d = 0.59) groups. Increases in anterior leg rotation in the weight-bearing lunge may be due to decreased passive stiffness in the plantar structures.

Abstract
Bell, ZW, Spitz, RW, Wong, V, Yamada, Y, Song, JS, Abe, T, and Loenneke, JP. Can individuals be taught to sense the degree of vascular occlusion? A comparison of methods and implications for practical blood flow restriction. J Strength Cond Res 36(12): 3359–3365, 2022—The study objective was to determine whether subjects could be conditioned to a relative blood flow restriction pressure in the lower body and compare 2 separate conditioning methods (unconstrained vs. constrained). Thirty-five subjects completed 4 visits, involving measurements for arterial occlusion and pressure estimations at 5 minutes and 24 hours after conditioning. The constrained method involved applying 40% of measured arterial occlusion 11 times, along with 10% above and below this pressure. The unconstrained method was time-matched, involving a series of inflations to 40% arterial occlusion for 12 seconds and then deflated for 22 seconds. Data are presented as mean differences (95% credible interval) unless otherwise noted. The absolute error between conditioning methods was found to be similar at 5 minutes (−1.1 [−5.9, 3.7] mm Hg) and 24 hours (−2.4 [−7, 2.2] mm Hg) after conditioning. The constant error differed between methods at 5 minutes [−8.2 (−14.4, −1.9) mm Hg] but was similar at 24 hours (−2.5 [−8.5, 3.6] mm Hg; H0: 0.680; H1: 0.068; and H2: 0.252) after conditioning. The bias and 95% limits of agreement for the unconstrained method were −3.9 (−33.8, 25.9) mm Hg at 5 minutes and −2.9 (−32, 26.1) mm Hg at 24 hours. The agreement for the constrained method was 4.2 (−28, 36.5) mm Hg at 5 minutes and −0.54 (−37.3, 36.2) mm Hg at 24 hours. Conditioning methods produced similar levels of absolute error, indicating that either method may offer a viable means of pressure application. Most estimates were between 20 and 60% of arterial occlusion pressure. Additional conditioning sessions may be needed to narrow this range at the individual level.
Resultados funcionales de las fracturas desplazadas del cuello del radio en niños: correlación entre las medidas de resultado informadas por el paciente (PROMIS y QuickDASH)
Authors: Tourn Diego , Masquijo Julio Javier 
Published: October 2021

Introducción: Nuestros objetivos fueron: 1) evaluar los resultados subjetivos en pacientes esqueléticamente inmaduros que habían sido sometidos a una cirugía por fracturas desplazadas del cuello del radio, 2) comparar el desempeño del PROMIS y QuickDASH y 3) evaluar los efectos de piso y techo de las medidas de resultado.
Materiales y Métodos: Se evaluaron los datos demográficos, las lesiones asociadas, el tipo de fractura, la técnica quirúrgica y las complicaciones. La evaluación funcional se realizó con la escala QuickDASH y el instrumento PROMIS (Upper Extremity/Strength/Pain Interference). Las correlaciones de las escalas se efectuaron con el coeficiente rho de Spearman. El valor alfa se estableció en 0,05.
Resultados: Se incluyó a 26 pacientes (13 varones) con una edad promedio de 7.5 años. El seguimiento promedio fue de 31 meses. Hubo correlaciones significativas entre las métricas QuickDASH y PROMIS Upper Extremity posoperatorias (rs = -0,64; p = 0,003). No se halló una correlación entre PROMIS Pain Interference y PROMIS Strength con el QuickDASH (rs = 0,001; p = 0,966 y rs = -0,39; p = 0,101, respectivamente). Se observaron efectos de techo o piso en todas las escalas.
Conclusiones: Hubo una marcada correlación entre el PROMIS Upper Extremity y el QuickDASH para evaluar los resultados después de la cirugía de fracturas del cuello del radio en niños. Sin embargo, todas las medidas tuvieron marcados efectos de piso y techo, probablemente debido al tamaño de la cohorte y a que un alto porcentaje de estas fracturas suelen tener resultados clínicos favorables.

Abstract
The severity and frequency of operational loss events show high variability across the globe. In this paper, we first examine the extent to which the quality of country-level governance measured by the Worldwide Governance Indicators explains cross-country variation of operational losses. We use the comprehensive database of SAS OpRisk Global for the period of 2008–2019 covering 132 countries and 8,144 loss events with a total loss amount of almost 490 billion USD. Our findings indicate that the governance indicators lost their explanatory power over the past decades, which contradicts the academic consensus and calls for new explanatory variables. To find these variables, we hypothesize that the changes are driven by some important megatrends such as economic development and technological advancement, globalization, and sustainability. Accordingly, we propose an extended model where the number of mobile subscribers, the export to GDP ratio, and the poverty headcount ratio were significant for the frequency. For severity, only GDP is a significant and robust explanatory variable. Investors, regulators, and analysts should, therefore, concentrate on these factors if they wish to model, manage, or mitigate operational risks.
The Effect of Pre-Class Assignment in Enhancing the Chinese National-Type School Pupils in Mastery Chinese Language
Authors: Ling Ke Bing , Chew Fong Peng 
Published: October 2021

The KSSR curriculum system introduced by Malaysia's ministry of education is demanding teachers to build pupils who will have the ability to carry out the learning process independently. To build pupils with the ability to learn independently, the pre-class assignment is an implementation needed to give the learning autonomy back to pupils. However, some of the teachers do not like students to do any pre-class assignment because they are afraid that students who have already obtained a certain level of understanding towards the learning materials would feel boring and show the signs of being not interested to listen during the in-class learning process. Thus, this study aims to study the effect of pre-class assignments in enhancing the Chinese language reading comprehension mastery level of pupils from Chinese national-type schools in order to convince more educators to start practicing the use of pre-class assignments. A group of 260 pupils from eight different schools in Kuala Lumpur was involved in this study. A quantitative approach was used in this study and tests were developed and used in this study. The result of this study showed that the implementation of pre-class assignments was effective in helping pupils to master Chinese language reading comprehension. The finding of this research showed that the pupils' performance in Chinese language reading comprehension was not affected by the language used at home and prior exposure of pupils towards pre-class assignments.

Published: October 2021

Lumbar epidural block is a commonly used procedure for providing anaesthesia, post-operative analgesia in all groups of patients irrespective of age, sex, weight and height of the patients. The knowledge of posterior space is important in view of the fact that this is the space where drugs for epidural anaesthesia/ analgesia are used. The knowledge of variability of this space with physical parameters of the patient, help us in reducing the incidence of total spinal anaesthesia.Two hundred adult patients in the age group of 20-60 years requiring subarachnoid block were chosen for the study. Using 22G Quincke spinal needle, epidural space was identified and skin epidural distance was measured. Proceeding the spinal needle further, causes needle to lie in subarachnoid space. The skin subarachnoid distance was measured. The difference between skin-subarachnoid distance and skin epidural distance denoted the posterior epidural space width. Its correlation with physical parameters was studied.Mean skin epidural distance was 4.30 ±0.57 in lateral position and 4.05 ± 0.57 in sitting position, the difference being statistically significant. (P= 0.002). There was positive correlation between skin epidural distance with weight, BMI and abdominal girth of the patient. Mean posterior epidural space depth was 0.468+14 cm in lateral position and 0.459+0.14 cm in sitting position, the difference being statistically insignificant. There was a positive correlation between posterior epidural space depth and height of the patient.The skin epidural distance varies with weight, BMI, abdominal girth and position of the patient. The posterior epidural space depth varies with the height of the patients.

In anesthesia propofol induction is administered at a dose of 2mg/kg as a single bolus and when given at this dose the commonest problem faced by the anesthetist is the sudden drop in the blood pressure, as the hypotensive effect of propofol is proportional to the dose and rate of administration.To study the effect of auto co-induction (priming principle) in the requirement of induction dose of propofol and the resulting hemodynamic parameters. A prospective randomized double blinded study was conducted for a period of one year in the department of anesthesia at a government medical college hospital in TamilNadu. A total of 60 patients were selected for our study and were randomly allocated into two groups of 30 each. Group A is the study group (priming) and group B is the control group (non-priming group). In the priming group, three minutes after premedication the co induction agent was administered (25% of the calculated dose of propofol) and two minutes later the patient received propofol at a rate of 30mg/10 sec until loss of vocalization was achieved. The hemodynamic parameters along with the total dose requirement of propofol and BIS values were monitored at regular intervals after induction.The mean total dose of propofol required among the priming group patients was 78.2 mg compared to the total dose requirement in the non-priming group which was 92.5 mg and the mean difference was found to be statistically significant. A statistically significant fall in the heart rate and blood pressure was observed at 1 min and 3 mins after induction in non priming group compared to priming group. By applying priming principle the induction dose of propofol was reduced by 14.25% with a good hemodynamic stability.
Comparative analysis of caudal ropivacaine with clonidine vs ropivacaine alone with regards to hemodynamic changes, analgesic potency and side effects in children
Authors: Vangani Mahendra , Soni Deepak 
Published: October 2021

Pain management is an essential component of care provided by pediatric anaesthesiologists. That specially holds true due to inability of this group of patients to report their overall experience of surgical procedures like adults. Caudal analgesia is one of the most popular regional anaesthetic techniques employed in children undergoing surgery for lower abdominal, urological, and lower limb operations. Of all the major advantages that this technique has, there is one major disadvantage of short duration of anesthesia. In children it is observed that combination of ropivacaine and clonidine administered caudally has shown to prolong the effects of analgesia. The present clinical study is therefore undertaken to compare caudal ropivacaine with clonidine and ropivacaine alone with regards to hemodynamic changes, analgesic potency and side effects in children.This study included 60 children of the age group 5-10 years ASA grade I and II, of either sex, coming for various elective infra-umbilical surgical procedures who were divided into two groups each comprising of 30 subjects. Group A received plain 0.20% Ropivacaine (1ml/kg) and Group B received 0.20%Ropivacaine (1ml/kg) with clonidine 1µg/kg and the effects were analysed on various parameters.In our study, we chose 0.20% ropivacaine which provides better quality of analgesia and clonidine 1.0μg/kg which prolongs the duration of analgesia significantly while avoiding the side effects like excessive sedation and bradycardia associated with higher doses. Other hemodynamic parameters did not differ significantly in both the groups.

The subclavian vein is the preferred site for central venous catheter insertion because of its several advantages. Infraclavicular is the commonly used approach while supraclavicular is less popular approach for catheterizing the subclavian vein. The aim of the study was to compare supraclavicular and infraclavicular approach of subclavian vein catheterization in terms of number of attempts, success rate, access time for catheterization and to record the complications associated with the procedure. In this study, 120 patients of inclusion criteria were placed either in group supraclavicular (SC) or group infraclavicular (IC) for subclavian vein catheterization using modified Seldinger technique under general or local anaesthesia.Chi square test was used to compare success rate and independent T test for access time of catheterization between two groups. First attempt success rate in group SC was 81.66% and in group IC was 66.66%. But overall success rate was 93.33% in group SC, whereas it was 90% in group IC. This was not statistically significant with p value of 0.5. Time taken for successful catheterization was 252.98 ± 76.27 seconds in group SC and 314.98 ± 121.28 seconds in group IC. This was statistically significant with p value of 0.001.Right brachiocephalic vein tear was the only complication in entire study which occurred in group IC. Subclavian vein catheterization via supraclavicular approach was a faster approach than infraclavicular, whereas both were comparable in terms of success rate.
Effect of intrathecal buprenorphine on the haemodynamic response in patients undergoing laparoscopic appendicectomy under general anaesthesia
Authors: Palayil Azim 
Published: October 2021

: Combined regional and general anaesthesia for laparoscopic appendicectomy offers better intraoperative haemodynamic stability. Buprenorphine is a long acting opioid which can be administered intrathecally and provides excellent analgesia intraoperatively and post operatively while allowing early ambulation without prolonged motor block. The study aimed to compare the haemodynamic response during laparoscopic appendicectomy using combined general anaesthesia with intrathecal buprenorphine and general anaesthesia alone. In this observational study 80 patients who underwent laparoscopic appendicectomy were divided into two groups of 40 each by random sampling. The patients in the GA group received general anaesthesia whereas patients in the GA+SAB group received intrathecal buprenorphine along with general anaesthesia. The heart rate, systolic and diastolic blood pressures and SpOwere noted after induction of general anaesthesia, immediately after endotracheal intubation, after creating pneumoperitonium and post extubation. Student’s t test was used for comparing the haemodynamic variables There were no statistically significant differences between GA and GA+SAB group in the heart rate, systolic and diastolic blood pressure after pneumoperitonium was created. When compared to general anaesthesia alone, addition of intrathecal burenorphine provides little advantage in preventing stress response during laparoscopic appendicectomy.
