Epidemiology of paediatric head and facial injuries in Queensland, Australia
Authors: Alsayad Fatima 
Published: March 2021

IntroductionHead and facial injuries in paediatric patients are a major public health problem in Queensland, Australia, where control, minimisation, or prevention play key roles. Although many studies have been reported, few can be found concerning the epidemiology of paediatric maxillofacial injuries in Queensland, Australia. The aim of this study was to retrospectively assess and report the aetiology, patterns, distribution, and associated factors of head and facial injuries in children in Queensland, Australia.Material and methodsData were obtained from Queensland injury Surveillance Unit (QISU). A retrospective study included 10,723 injured children (from less than 1 year old to 12 years old) in the years 2012, 2013, 2014, 2015, and 2016. The analyses involved descriptive statistics and 2 test.ResultsThe number of patients injured varied among age groups. The nature and mechanism of injuries were different among age groups as well. Boys were more prone to maxillofacial injuries compared to females. The highest rate of injuries was in the 1–2-year age group for both genders. Contact with a static object was the main aetiology of maxillofacial injuries during leisure activity (playing). The home was the main site where the injuries occurred.ConclusionsPreventive measures should be strengthened both indoors and outdoors to reduce the incidence and severity of paediatric injuries in Queensland, Australia. In addition, children in the growing phase should be monitored periodically. Furthermore, increasing awareness can be attained by increasing safety education.

PurposeThe aim of our study was to analyse the effect of a single-cycle ischaemic preconditioning (IPC) protocol on performance in the 100-m front crawl swimming modality.MethodsOverall, 16 swimmers were recruited: 8 female athletes (12.9 ± 0.88 years) and 8 male athletes (13.1 ± 0.88 years). In a randomized crossover design, all participants performed a 100-m front crawl sprint preceded by an IPC or placebo cycle. In the IPC trial, a pneumatic cuff was attached to the proximal thigh and was inflated at a pressure equivalent to 80% of arterial occlusion and remained inflated for 5 min (ischaemia); in the placebo trial, the cuff remained inflated for the same amount of time, but at low external pressure levels (20 mm Hg). The volunteers started the test 5 min after cuff pressure release (reperfusion).ResultsIt was not possible to verify significant differences within the time (seconds) required to complete the test between the IPC and placebo interventions (75.68 ± 7.2 and 75.75 ± 8.1 s, respectively; <i>p</i> = 0.916).ConclusionsTherefore, we can conclude that the tested IPC protocol does not seem to be sufficient to provide performance improvement in 100-m front crawl in young athletes.

PurposeTo investigate the patterns of recovery of ball possession in a young futsal team.MethodsSeven games played by a youth futsal team were analysed. Patterns of recovery of ball possession were investigated on the basis of the following variables: way to recover the ball, location of recovery, tactical behaviour after the recovery, and result of the match. One-way ANOVA and post-hoc Tukey honest significant difference test were used to compare the variables. Principal component analysis was also applied to verify the association between variables.ResultsIt was observed that there was a greater number of ball recoveries in the defensive sector (F<sub>3,24</sub> = 35.6; <i>p</i> < 0.001; η<sub>p</sub><sup>2</sup> = 0.79), that set pieces were the most frequent way to recover the ball (F<sub>5,36</sub> = 7.9; <i>p</i> < 0.001; η<sub>p</sub><sup>2</sup> = 0.46), that ball possession was maintained more often after the recovery of the ball (F<sub>3,24</sub> = 79.6; <i>p</i> < 0.001; η<sub>p</sub><sup>2</sup> = 0.90), and that there was no correlation between the result of the match and the number of ball recoveries (F<sub>3,24</sub> = 0.20; <i>p</i> = 0.93; η<sub>p</sub><sup>2</sup> = 0.10). Four components were identified that represented a variance of 95% for all variables. Factor 1 was related to the patterns of ball possession recovery in the offensive sector, while factor 2 was related to the tackle.ConclusionsIt was concluded that the way to recover the ball and the location of recovery affected both patterns of recovery and tactical behaviour after the recovery of the ball.

IntroductionCOVID-19 is a novel, severely contagious and progressive infection occurring worldwide. The diagnosis of the disease is based on real-time polymerase chain reaction (RT-PCR) and computed tomography (CT) scan, even though they are still controversial methods.Material and methodsWe studied 54 patients with suspected COVID-19 and the two mentioned methods were compared with each other.ResultsSensitivity and specificity of the abnormal chest CT scan, ground-glass opacity (GGO), consolidation opacity, and both of GGO and consolidation were also surveyed based on RT-PCR. The results showed that RT-PCR assay was negative in 23 (42.6%) patients and positive in 31 (57.4%) cases. Also, the patients with an abnormal chest CT scan comprised 37 (68.5%). The sensitivity and specificity of abnormal CT scan were 78.6% and 42.3%, respectively, based on the RT-PCR method.ConclusionsOther techniques alongside CT scan and RT-PCR are advocated for accuracy of the COVID-19 diagnosis.

We aim in the current study to review pulmonary and extra-pulmonary imaging features in patients infected with COVID-19. COVID-19 appears to be a highly contagious viral disease that attacks the respiratory system causing pneumonia. Since the beginning of the outbreak, several reports have been published describing various radiological patterns related to COVID-19. Radiological features of COVID-19 are classified into; pulmonary signs of which ground glass opacities are considered the characteristic followed by consolidation, and extra-pulmonary signs such as pulmonary embolism and pneumothorax, which are far less common and appear later in progressive disease. We review the different structured reporting systems that are published by different groups of radiologists using simple unified terms to enable good communication between the radiologist and the referring physician. Computed tomography of the chest is beneficial for early diagnosis of COVID-19 pneumonia, assessment of disease progression and guide to therapy, surveillance of patients with response to therapy, prediction of overlying bacterial infection, differentiation from simulating lesions, and screening with prevention and controls of the disease.

Published: March 2021

IntroductionTransarterial chemoembolization (TACE) is currently recommended for unresectable intrahepatic tumours with no vascular invasion or metastasis to other organs. It is based on drug-eluting microspheres pre-loaded with chemotherapeutics, which are injected selectively into vessels supplying the tumour, to embolize them inducing ischaemia, and elute the drug, to induce tumour response. We present our initial experience with novel irinotecan-loaded Embocure Plus microspheres in patients with metastatic colorectal cancer tumours in the liver, and their effect on HCT-116 cell cultures in vitro.Material and methodsThree consecutive male patients (median age 62 [50-76] years) with liver metastatic colorectal cancer tumours were selected. All patients had a pre-procedure contrast-enhanced computed tomography, confirming multiple metastatic liver tumours (mean tumour diameter = 42 mm; range: 14-77 mm) and periprocedural dyna-CT scans for rapid treatment results assessment. In vitro: Human colon HCT116 cancer cell line was cultured, irinotecan loaded Embocure Plus microspheres were added. Cultures were assessed after 24 hours and 72 hours of incubation in normoxia or hypoxia.ResultsAll embolizations were technically successful, and no complications were observed. Stabilization of the targeted metastatic liver tumours in all patients was noted. In vitro: Significant decrease of the growth of HTC 116 cell lines were observed in controls compared to cells treated with Embocure Plus loaded with irinotecan in normoxia and hypoxia after 48 and 72 hours. We observed a tendency for less inhibited cell proliferation in low-oxygen conditions.ConclusionsTACE therapy of liver metastatic tumours shows satisfactory results and a low complication rate. Embo­cure Plus microspheres are safe and technically feasible for superselective chemoembolization of metastatic colorectal cancer liver tumour. Dyna-CT can be used for assessment of treatment results during repeated TACE procedures.

IntroductionCarpal tunnel syndrome (CTS) is the most commonly encountered nerve entrapment disorder; it causes pain, numbness, tingling sensation in the hands and leads to work disability. The purpose of this study was to analyse the impact of shock wave and iontophoresis in patients with CTS.MethodsThis study was conducted in 30 patients with CTS of both sexes, aged 30–50 years. The patients were randomly allocated into 2 groups. Study group A received shock wave therapy and study group B received iontophoresis therapy.ResultsThe results revealed a higher improvement in group A than in group B. In group A, there were a significant increase of sensory nerve conduction velocity of median nerve and a significant decrease of pain after treatment, while in group B, there were a less significant increase of sensory nerve conduction and less significant reduction of pain after treatment. The inter-group comparisons showed statistically significant differences in favour of group A.ConclusionsShock wave is more effective than iontophoresis in the treatment of patients with CTS.

Usaha Mikro Kecil dan Menengah (UMKM) adalah pilar kekuatan perekonomian yang kokoh, hal ini dibuktikan oleh tetap eksisnya UMKM saat Indonesia di landa krisis moneter akibat imbas dari krisis ekonomi global. Sedangkan di sisi lain yaitu perusahaan dengan sekala besar banyak mengalami gulung tikar. Sehingga terjadi pemutusan hubungan kerja yang luar biasa di tahun 1998. Pemanfaatan tanaman aren di Indonesia sudah berlangsung lama, namun belum lama ini perkembangannya meningkat menjadi komoditi agribisnis. Karena sebagaian tanaman aren yang diusahakan adalah tumbuh secara alamiah atau belum dibudidayakan. Hasil produksi aren yang paling banyak diusahakan oleh masyarakat adalah nira, yang diolah untuk menghasilkan gula merah dan produk ini memiliki pasar yang sangat luas. Usaha pengolahan gula merah kedepannya mempunyai prospek yang baik. Tetapi harus ditopang dengan keberadaan bahan baku serta lahan yang memadai. Guna menunjang kegiatan proses produksi gula merah tersebut. Selain itu, modal yang digunakan untuk membeli berbagai alat investasi memulai suatu usaha. Kemudian tenaga kerja untuk mempermudah dalam suatu pekerjaan. Sehingga perlu diuji kelayakan usaha dan strategi pengembangan yang tepat untuk memajukan UMKM gula merah.

This analysis will discuss how to handle vibrations in the Turbine Rotor. The measuring instrument used is Vibration Analysis test with Prov. 2140 type which measured amplitude, time and frequency domain of vibration signal. The results obtained in this study, firstly, the measurement vibration of rotor at PT PJB Gresik found the highest amplitude of vibration was 59,6 μm at 3000 rpm. In this condition, the rotor is in very good condition as per standard vibration in ISO 7919-2 stated 80 μm at 3000 rpm. However in the next measurement, there is an dramatically increase of amplitude in each vibration measurement. The top amplitude of vibration reached at 115 μm at 3000 rpm and shown a symtom of damage on the rotor as a result of vibration. In solving the problem this time we use the method Root couse analysis (RCA). The results of this research found that there was a short turn to turn on the rotor windings and the closed slot liner holes that caused electric vibrations and needed to be repaired to eliminate vibration disturbances. After repairing the vibration, it decreased which initially 115 μm to 33.5 μm at 3000 Rpm, it is still on the range of the permitted safe zone of ISO standard 7919−2.
The Effect of Varying Concentrations and Application Periods of Chondroitinase ABC on Tissue-Engineered Cartilage
Authors: Tong Eric , O'Connell Grace D. , Kelly Terri-Ann N. , Hung Clark T. 
Published: March 2021

Osteoarthritis, a chronic malady characterized by joint pain and swelling, is caused by damage to articular cartilage and is perpetuated by low-grade inflammation. Treatments for osteoarthritis do exist, but many treatments focus on coping with the disease rather than curing it. Surgical options that replace damaged cartilage tissue with that of donor cartilage tissue or cartilage tissue from other parts of articular joints face complications especially when the tissue is not of the correct size or does not have native-like properties.
A more suitable treatment option for osteoarthritis is to develop an in vitro tissue-engineered cartilage construct that can be grown using the patient’s own cells and to surgically remove the patient’s damaged cartilage and replace it with the tissue-engineered cartilage. A challenge in developing such a treatment option is producing tissue-engineered cartilage with mechanical properties akin to those of native human articular cartilage. This challenge may be overcome by maximizing the production of type II collagen by the chondrocytes in vitro. One way to maximize collagen production is through the application of chondroitinase ABC, an enzyme which temporarily suppresses proteoglycans in the cartilage matrix to create more space for type II collagen to develop.
In this study, two two levels of cABC treatment were applied (“high” and “low”) to cartilage tissue constructs. The “low” cABC treated group received daily feeding of 0.075 U/mL from day 14 to 21 followed by a replacement of chondrogenic media without cABC. The “high” cABC treated group received a single addition of 0.15 U/mL from day 14 to 16 followed by a replacement of chondrogenic media without cABC. At the end of 42 days, the constructs were subjected to mechanical testing and biochemical analyses. These analyses showed that the high cABC treatment yielded more native-like mechanical properties when compared to the low cABC treatment and the control results. Biochemical and histological analyses confirmed that the proteoglycan and collagen II content were higher in the low and high cABC treated groups when compared to the control. All analyses show that the most efficient application of chondroitinase ABC is through a two day duration treatment of a higher concentration (0.15 U/mL).
“Philosophy Needs To Find A Place For Imagination Also In The Analysis Of Action”: Faculty Interview with Professor Katja Vogt
Authors: Basaran Ayda 
Published: March 2021

In her recent project, Imagination and Agency, Professor Vogt addresses the gap between the philosophical theory and empirical research. I was curious about how this project aims to incorporate philosophical questions into an interdisciplinary debate.
She explains that there is a significant body of empirical work on mental simulation and imagination as components of agency, since philosophers have also long been interested in imagination. However, philosophers tend to focus on what are called “lofty domains”: thought experiments, science, and art. Vogt argues that philosophy needs to find a place for imagination also in the context of the analysis of action. She thinks that it’s a long-standing idea that, when you make a decision, you decide between options that you consider possible. This is why her project examines the modal scope, the study of ways in which propositions can be true or false, of agential thought, since decision making is concerned with what is and what is not possible. As an example, she cites Aristotle, , who argued that no one deliberates about whether to become a god, because it’s impossible to become a god.
“Moving Past Time Itself to See Changes Happen”: Faculty Interview with Dominic Walker
Authors: Sun Shannon 
Published: March 2021

On the corner of Dominic Walker’s desk lies a neat stack of books. Juxtaposed against each other, two of the titles read, “Best of the Best” and “Unequal Childhoods.” These books, decorative elements on an otherwise barren desktop, were a humble display of the larger questions that occupied Walker’s academic research and personal life.
At age 26, Walker, a Ph.D. candidate in Sociology at Columbia University, is pursuing research on the interwoven systems of privilege that give rise to inequality. Originally from Baltimore, Maryland, Walker draws extensive inspiration from his upbringing in drastically different school systems. Growing up in a single-parent household, Walker first attended a public elementary school in Baltimore, earned a sponsorship to an all-boys Catholic middle school, and then left home to attend a prestigious, all-boys boarding high school in Virginia. With each move, Walker became more acutely aware of the reason for his departure.
