The Gulf of Carpentaria and Torres Strait in north‐eastern Australia support globally significant seagrass ecosystems that underpin fishing and cultural heritage of the region. Reliable data on seagrass distribution are critical to understanding how these ecosystems are changing, while managing for resilience. Spatial data on seagrass have been collected since the early 1980s, but the early data were poorly curated. Some was not publicly available, and some already lost. We validated and synthesized historical seagrass spatial data to create a publicly available database. We include a site layer of 48,612 geolocated data points including information on seagrass presence/absence, sediment, collection date, and data custodian. We include a polygon layer with 641 individual seagrass meadows. Thirteen seagrass species are identified in depths ranging from intertidal to 38 m below mean sea level. Our synthesis includes scientific survey data from 1983 to 2022 and provides an important evidence base for marine resource management. [ABSTRACT FROM AUTHOR]

This study aimed to determine whether the Relative Age Effect (RAE) was present in different sexes and age categories in 12 elite-level international amateur boxing competitions. A total of 4813 athletes competing between 2013 and 2022 were analysed. Athletes were split into four quartiles according to their birth date and compared to the expected (equal) birth date distribution using chi-squared goodness of fit. The results revealed greater RAE prevalence in youth compared to the senior group. RAE was more prominent in males compared to females, with the female group showing an inverse RAE trend. Odds ratio (OR) showed an overrepresentation of male boxers born in Q1 compared to Q4 (OR > 1.19-1.33), while senior female boxers presented an inverse trend (OR < 0.95). Odds Ratios for medallists within the youth group were greater than 1.07 (except Q3 × Q4 = 0.93) highlighting an overrepresentation of boxers born earlier in the year. A shift in strategy to reduce the RAE in young boxers whereby coaches focus less on the short-term pursuit of sporting success is encouraged. Organisations and coaches should increase awareness and provide systematic education around RAE, whilst creating equal competitive opportunities for all young boxers to reduce the extent of RAE in boxing.

Acute respiratory failure (ARF) strikes an estimated two million people in the United States each year, with care exceeding US$50 billion. The hallmark of ARF is a heterogeneous injury, with normal tissue intermingled with a large volume of low compliance and collapsed tissue. Mechanical ventilation is necessary to oxygenate and ventilate patients with ARF, but if set inappropriately, it can cause an unintended ventilator-induced lung injury (VILI). The mechanism of VILI is believed to be overdistension of the remaining normal tissue known as the 'baby' lung, causing volutrauma, repetitive collapse and reopening of lung tissue with each breath, causing atelectrauma, and inflammation secondary to this mechanical damage, causing biotrauma. To avoid VILI, extracorporeal membrane oxygenation (ECMO) can temporally replace the pulmonary function of gas exchange without requiring high tidal volumes (V T ) or airway pressures. In theory, the lower V T and airway pressure will minimize all three VILI mechanisms, allowing the lung to 'rest' and heal in the collapsed state. The optimal method of mechanical ventilation for the patient on ECMO is unknown. The ARDSNetwork Acute Respiratory Management Approach (ARMA) is a Rest Lung Approach (RLA) that attempts to reduce the excessive stress and strain on the remaining normal lung tissue and buys time for the lung to heal in the collapsed state. Theoretically, excessive tissue stress and strain can also be avoided if the lung is fully open, as long as the alveolar re-collapse is prevented during expiration, an approach known as the Open Lung Approach (OLA). A third lung-protective strategy is the Stabilize Lung Approach (SLA), in which the lung is initially stabilized and gradually reopened over time. This review will analyze the physiologic efficacy and pathophysiologic potential of the above lung-protective approaches., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a major bacterial pathogen., Aim: The present study aimed to determine the incidence of MRSA infections among kidney dialysis patients and the antibiotic susceptibility patterns and investigate the prevalence of mecA gene among MRSA isolates., Materials and Methods: A total of 83 nasal sterile cotton swabs samples were obtained from hemodialysis patients from Al-Karak Governmental Hospital, Al-Karak, Jordan. Collected and cultured on nutrient agar and mannitol salt agar and incubating at 37°C for 24-48 hours, Staphylococcus aureus ( S. aureus ) strains were identified by gram stain, coagulase test, and catalase tests. The MRSA isolates were tested for the presence of MecA and SCCmec genes using the Xpert SA Nasal Complete assay real-time PCR. Factors such as age and gender were included in the study. The antibiotic profile tested by using the disc diffusion method tested all MRSA isolates., Results: This study showed that 10.8% of the cultures' growth was S. aureus and 9.6% of all the patients were infected with MRSA, with no relationship between the number and frequency of MRSA according to the patient's gender or age. All MRSA (100%) isolates have both genes (MecA genes and SCCmec genes), and all samples were resistant to oxacillin, ceftazidime, cefoxitin, aztreonam, and ampicillin., Conclusion: The MRSA prevalence was determined among kidney dialysis patients in the hospital. All positive samples were resistant to oxacillin, ceftazidime, cefoxitin, aztreonam, and ampicillin, which is a very rare finding, and this will give the scientists and doctors a dangerous indication about health-care centers in the Al-Karak city of Jordan., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2023 Omar Al-Dmour et al.)

The conduct of cardiopulmonary bypass in neonatal, infant, and pediatric patients continuously evolves as new devices and innovative techniques are introduced. Since 1989, periodic pediatric perfusion surveys have been conducted to ascertain practice patterns involving demographics, equipment, and perfusion techniques. The goal of this current project is to provide an updated perspective on international pediatric and congenital perfusion practice since the last survey conducted in 2016. In July 2021, a 100-question perfusion survey was distributed to 284 pediatric cardiac surgery centers using a secure web browser-based data application. Each center was given a unique survey hyperlink to ensure one response per institution and to monitor the response rate. Centers were given 1 month to complete the survey and electronic reminders were sent weekly to nonrespondents. After the survey was closed, information from completed surveys was exported to a software program for analysis. Responses were received from 153 of 284 pediatric centers for a response rate of 54%. Sixty respondents (39%) were from North American (NA) centers while 93 respondents (61%) were from non-North American (NNA) centers. The vast majority of centers use a roller head arterial pump (93%), hollow fiber oxygenators with open reservoirs (86%), and integrated arterial line filters (73%). The use of modified ultrafiltration was reported by 76% of centers. Ninety-two percent of centers reported the use of selective antegrade cerebral perfusion for aortic arch repairs. The N + 1 staffing model was most prevalent (52%), followed by two perfusionists per case (33%). Periodic surveys continue to be a useful modality in assessing regional variation in pediatric perfusion practice. This survey marked the first time the majority of responses came from non-North American institutions. Identifying these practice patterns may aid in the development of, and adherence to, regional standards and guidelines. This would foster the reduction of variation in practice and potentially improve patient safety., (© Copyright 2022 AMSECT.)

The COVID-19 pandemic represents the most significant global challenge in a generation. Based on extant data from previous pandemics, demographic, occupational, and psychological factors have been linked to distress and for some vulnerable members of society. COVID-19 has added to the layers of grief and distress of existing trauma. Evidence-based frameworks exist to guide our individual and collective response to reduce the trauma associated with the experience of a pandemic. Pandemic and post-pandemic measures to ameliorate impacts require a multi-disciplined approach, central to which is community connectedness, resilience, and access to support. We advocate for the acceptance and broader application of Dadirri, a healing practice held by the Ngan'gikurunggurr and Ngen'giwumirri Aboriginal people of the Daly River region in the Northern Territory, Australia. This modality engages therapeutic phases that are comparable with other practiced trauma therapies. The demonstrated therapeutic outcomes from Dadirri can be attained through an individualistic or in a relational engagement context. This practice is accessible to all ages, is non-specific to gender and is suitable for people constrained in their mobility or limited by resources, pertinent in pandemic affected settings., Competing Interests: CA was employed by the company We Al-li Pty Ltd.

Small increases in serum creatinine postoperatively reflect an acute kidney injury (AKI) that likely occurred during cardiopulmonary bypass (CPB). Maintaining adequate oxygen delivery (DO 2 ) during CPB, known as GDP (goal-directed perfusion), improves outcomes. Whether GDP improves outcomes of patients at high risk for acute renal failure (ARF) is unknown. Forty-seven adult patients undergoing cardiac surgery with CPB utilizing GDP with Cleveland Clinic Acute Renal Failure Score of 3 or greater were compared with a matched cohort of patients operated upon using a flow-directed strategy. CPB flow in the GDP cohort was based on a DO 2 goal of 260 mL/min/m 2 . Serum creatinine values were used to determine whether postoperative AKI occurred according to AKIN (Acute Kidney Injury Network) guidelines. We examined the distribution of all variables using proportions for categorical variables and means (standard deviations) for continuous variables and compared treatment groups using t tests for categorical variables and tests for differences in distributions for continuous and count variables. We used inverse probability of treatment weighting to adjust for treatment selection bias. In adjusted models, GDP was not associated with a decrease in AKI (odds ratio [OR]: .97; confidence interval [CI]: .62, 1.52), but was associated with higher odds of ARF (OR: 3.13; CI: 1.26, 7.79), mortality (OR: 3.35; CI: 1.14, 9.89), intensive care unit readmission (OR: 2.59; CI: 1.31, 5.15), need for intraoperative red blood cell transfusion (OR: 2.02; CI: 1.26, 3.25), and postoperative platelet transfusion (OR: 1.78; CI: 1.05, 3.01) when compared with the historic cohort. In patients who are at high risk for postoperative renal failure, GDP was not associated with a decrease in AKI when compared to the historical cohort managed traditionally by determining CPB flows based on body surface area. Surprisingly, the GDP cohort performed significantly worse than the retrospective control group in terms of ARF, mortality, intensive care unit readmission, and RBC and platelet transfusions., (© Copyright 2022 AMSECT.)

Standards and guidelines for cardiopulmonary bypass have been established by various professional societies. They serve as an instrument to guide safe and effective patient care. We conducted a survey of practicing perfusionists in Kenya to learn about their background, education, current clinical practice and about their knowledge, and attitude regarding standards and guidelines. Two multiple-choice surveys were distributed to all known practicing perfusionist in Kenya using SurveyMonkey (San Mateo, CA). Multiple-choice questions related to professional background, training, annual procedure volume, staffing models, clinical practices, the use of safety devices, and the use of checklists were included in the questionnaires. The survey also inquired about familiarity with American and European perfusion practice standards and guidelines and opinions on establishing standards in Kenya. Responses were received from 12 perfusionists practicing at 10 centers. Professional backgrounds included anesthesia nursing, clinical officers, and critical care nursing. Sixty-seven percent (8/12) received formal training and 33% (4/12) trained primarily through clinical instruction. Of those that received formal training, 63% (5/8) received 1-2 years of training, 25% (2/8) <1 year but more than 6 months, and 12.5% (1/8) received 6 months of formal training. The median clinical experience was 5 years (range 1-22). The median annual case load was 54 (range 0-100). Use of safety devices was reported as follows: level sensor 75% (9/12), air bubble detector 17% (2/12), one-way vent valves 67% (8/12), continuous venous oxygen saturation monitoring 25% (3/12), and gas supply analyzers 33% (4/12). More than one-third of the respondents had no knowledge of the American and European perfusion practice standards, and nearly two-thirds were aware of or had read them. This survey provides contextual information about perfusion practice in Kenya in 2021. There was consensus among perfusionists to develop standards and practice guidelines for Kenya., (© Copyright 2022 AMSECT.)
