Weaning from Impella and mobilization of Impella patients

Weaning of patients from Impella is complex and includes evaluation of the underlying disease, which is essential for estimating the potential for heart recovery. Monitoring during the weaning phase with echocardiography and pulmonary artery catheters will be discussed, as well as the use of intravenous and oral heart failure drugs. Patients who are candidates for weaning must be stable, without inotropes, and must have recovered from acute end-organ damage. Coronary artery disease and valvular heart diseases should be appropriately addressed before weaning to take the maximum advantage of haemodynamic stability provided by the support and to maximize the possibility of weaning. Tips and tricks for the mobilization of Impella patients will also be discussed.

Revision of the Australian soldier fly genus Antissella White, 1914, including six new species (Stratiomyidae: Antissinae)

Antissella White, 1914 is a small genus of soldier flies endemic to Australia, previously thought to comprise only two described species and suspected to have a role in pollination. Six new species of Antissella are named, described and illustrated herein, and an updated identification key to all known species is provided. The new species include: Antissella alicespringsensis Lessard & Woodley sp.n., Antissella elongata Lessard & Woodley, sp.n., Antissella kalbarriensis Lessard & Woodley sp.n., Antissella nigricentralis Lessard & Woodley sp.n., Antissella ottensorum Lessard & Woodley, sp.n., and Antissella purprasina Lessard & Woodley, sp.n. A lectotype and paralectotype are also selected for Antissella quinquecella (Macquart, 1846). Eight species of Antissella are now recognised from Australia. Three of the new species are known from areas burned by the devastating 2019/2020 Australian summer bushfires. Now that they are formally named and described, the species may be recognised in future bushfire recovery monitoring programs.

Sensor array for wireless remote monitoring of carbon dioxide and methane near carbon sequestration and oil recovery sites

Demonstration of a solar-powered sensor array for remote carbon sequestration and enhanced oil recovery monitoring. An unattended sensor array can collect real-time gas concentrations, allow leak detection, and measure daily concentration cycles.

The Reliability of Neuromuscular and Perceptual Measures Used to Profile Recovery, and the Time-Course of Such Responses Following Academy Rugby League Match-Play

In professional academy rugby league (RL) players, this two-part study examined; (A) the within- and between-day reliability of isometric mid-thigh pulls (IMTP), countermovement jumps (CMJ), and a wellness questionnaire (n = 11), and (B) profiled the responses with acceptable reliability (no between-trial differences and between-day coefficient of variation (CV) ≤10% and intraclass correlation coefficient (ICC) ≥0.8) for 120 h (baseline: −3, +24, +48, +72, +96, +120 h) following RL match-play (n = 10). In part A, force at 200, and 250 ms, and peak force (PF) demonstrated acceptable within- (CV%: 3.67–8.41%, ICC: 0.89–0.93) and between-day (CV%: 4.34–8.62%, ICC: 0.87–0.92) reliability for IMTP. Most CMJ variables demonstrated acceptable within-day reliability (CV%: 3.03–7.34%, ICC: 0.82–0.98), but only six (i.e., flight-time, PF, peak power (PP), relative PP, velocity at take-off (VTO), jump-height (JH)) showed acceptable between-day reliability (CV%: 2.56–6.79%, ICC: 0.83–0.91). Only total wellness demonstrated acceptable between-day reliability (CV%: 7.05%, ICC: 0.90) from the questionnaire. In part B, reductions of 4.75% and 9.23% (vs. baseline; 2.54 m∙s−1; 0.33 m) occurred at +24 h for CMJ VTO, and JH, respectively. Acceptable reliability was observed in some, but not all, variables and the magnitude and time-course of post-match responses were test and variable specific. Practitioners should therefore be mindful of the influence that the choice of recovery monitoring tool may have upon the practical interpretation of the data.

Lacrosse Athletes Load and Recovery Monitoring: Comparison between Objective and Subjective Methods

Both objective (OM) and subjective (SM) methods are used in athletic studies, regardless of sport type, to identify and analyze load and recovery status of athletes. As little information exists about the comparison of these two methodologies, the aim of this study is to compare and contrast information that defines the relationship between both methods. Twelve international male lacrosse athletes participated in this study over the course of which participants heart-rate-variability and questionnaire-data were collected. Statistical analysis was performed to evaluate changes over time and correlations between used methods. Comparison between baseline values and competition showed a reduction in root-mean-square of successive differences (RMSSD) (p < 0.01) and the proportion of beat-intervals (NN) that differ by more than 50 ms divided by total number of NNs (pNN50) (p < 0.01). Further, RMSSD values showed differences during competition with large effects (p = 0.02; η2 = 0.24). SM (p < 0.01) showed different progression during competition. Correlation was found for used SM and OM, when considered separately. No evidence for a reliable prediction of OM values using SM could be found. According to these findings, we recommend using a combination of SM and OM data to quantify the physiological stress of training and competition, respectively.
