Abstract
Australia as a continent represents a semi-arid environment that is generally water-limited. Changes in rainfall pattern will inevitably occur due to rising temperatures caused by climate change, which has a direct impact on the distribution of Australia's vegetation (green cover). As variability in rainfall continues to increase, i.e., in frequency and/or magnitude, due to climate change, extreme climate events such as droughts are predicted to become more pervasive and severe that will have an adverse effect on vegetation. This study investigates the effects of extreme climate on Australia's green cover during 2003-2018 for the end of rainy seasons of April and October in the northern and southern parts, respectively, to (i) determine the state of vegetation and its changes, (ii) identify "hotspots", i.e., regions that constantly experienced statistically significant decrease in NDVI, and (iii), relate changes in the identified hotspots to GRACE-hydrological changes. These are achieved through the exploitation of the statistical tools of Principal Component Analysis (PCA) and Mann-Kendel Test on Gravity Recovery and Climate Experiment (GRACE) hydrological products on the one hand, and the utilization of Australia's rainfall product and Moderate Resolution Imaging Spectroradiometer Normalized Difference Vegetation Index (MODIS-NDVI) used here with its native spatial resolution of 0.002413∘ × 0.002413∘ on the other hand. Differences between 3-year intervals from 2003 to 2018 for both April and October datasets are used to quantify vegetation variations. Through area change analysis, the vegetation differences (2003-2018) indicate that April exhibited larger increase (13.77% of total vegetation area) than decrease (7.83%) compared to October, which experienced slightly larger decrease (9.41%) than increase (8.71%). South Australia and Western Australia emerge as "hotspots" in which vegetation statistically decreased in October, with no noticeable change in April. GRACE-based hydrological changes in both hotspots reflect a decreasing trend (2003-2009) and increasing trend (2009-2012) that peaks in 2011, which then transitions towards a gradually decreasing trend after 2012. Australia-wide climate variability (ENSO and IOD) influenced vegetation variations during the data period 2003 to 2018.

Abstract
Objective The aim of this study was to evaluate the efficacy of anakinra in patients who were admitted to hospital for severe COVID-19 pneumonia requiring oxygen therapy. Methods A prospective, open-label, interventional study in adults hospitalized with severe COVID-19 pneumonia was conducted. Patients in the interventional arm received subcutaneous anakinra (100 mg twice daily for 3 days, followed by 100 mg daily for 7 days) in addition to standard treatment. Main outcomes were the need for mechanical ventilation and in-hospital death. Secondary outcomes included successful weaning from supplemental oxygen and change in inflammatory biomarkers. Outcomes were compared with those of historical controls who had received standard treatment and supportive care. Results A total of 69 patients were included: 45 treated with anakinra and 24 historical controls. A need for mechanical ventilation occurred in 14 (31%) of the anakinra-treated group and 18 (75%) of the historical cohort (p < 0.001). In-hospital death occurred in 13 (29%) of the anakinra-treated group and 11 (46%) of the historical cohort (p = 0.082). Successful weaning from supplemental oxygen to ambient air was attained in 25 (63%) of the anakinra-treated group compared with 6 (27%) of the historical cohort (p = 0.008). Patients who received anakinra showed a significant reduction in inflammatory biomarkers. Conclusion In patients with severe COVID-19 pneumonia and high oxygen requirement, anakinra could represent an effective treatment option and may confer clinical benefit. Trial registration number ISRCTN74727214.

Abstract
Background Pediatric human immunodeficiency virus (HIV) is an important emerging disease and many children are surviving into adulthood with effective antiretroviral therapy. Growth dysregulation is common in these children and endocrine abnormalities are likely to be a possible comorbidity. There is a paucity of data on these endocrinological abnormalities in this population. Against this background, a study to evaluate the endocrinological profile in HIV-infected children and its relationship with growth failure was performed.
Methods A cross-sectional descriptive study was performed in children less than 18 years attending the pediatric HIV clinic at a tertiary care hospital in central India. Blood samples for T3, T4, thyroid-stimulating hormone (TSH), growth hormone (GH), dehydroepiandrosterone (DHEA), cortisol, and insulin-like growth factor-binding protein 3 (IGFBP3) were collected during routine visit, preserved at –70°C, and subsequently assayed. Statistical analysis for the data with respect to the endocrinological abnormalities and growth failure was performed.
Results A total of 100 children were included in the study. The prevalence of growth failure was high. Nineteen percent children had height less than − 3 standard deviation (SD) and 59% children had height less than 2SD. The prevalence of endocrinological abnormalities was also high. Fifty-four percent children had low T3 levels, 12% had low T4 levels, 4% had high TSH levels, 44% had low cortisol levels, and 25% had low DHEA. Fifty-eight percent children had low GH levels, while IGFBP3 levels were low in the entire cohort. There was a statistically significant association between growth failure and levels of T3 and GH.
Conclusion Our results show a high prevalence of growth failure and endocrinological abnormalities in HIV-infected children. A significant association between growth failure and endocrine abnormalities was found for T3 and GH.

Abstract
OBJECTIVES To determine the prevalence and predictors of gestational diabetes mellitus (GDM) as well as acceptability of returning for glucose tolerance testing among pregnant women in Moshi municipality, northern Tanzania. METHODS Cross-sectional study from October 2015 to April 2016 among women with gestation age of 24-28 weeks of pregnancy attending at Kilimanjaro Christian Medical Centre (KCMC) referral hospital, Majengo and Pasua Health Centres. Women were interviewed and requested to return the next day (window within a month, depending on gestational age) for fasting plasma glucose (FPG) testing, followed immediately by a 75 g oral glucose tolerance test (OGTT). GDM was diagnosed using the 2013 WHO criteria. Logistic regression was conducted to reveal independent predictors for GDM. RESULTS Of 433 interviewed women, 100 (23%) did not return for FPG and OGTT testing. The prevalence of GDM among the 333 screened women was 19.5%, and 3% had diabetes in pregnancy (DIP). GDM was significantly associated with age ≥35 years (adjusted OR 6.75), pre-pregnancy obesity (AOR 2.22) and history of abortion (AOR 2.36). CONCLUSION Prevalence of GDM is high in Moshi. We recommend introduction of routine screening for hyperglycaemia during pregnancy along with strategies for follow-up to prevent long-term effects of GDM and DIP in women and their children.

Abstract
OBJECTIVE Compared to other chest wall malignancies, lymphoma is a common disease. However, published literature on a series of lymphoma cases involving the chest wall is scarce. The aim of the present study, was to describe experience with chest wall swellings diagnosed as lymphoid neoplasms on fine needle aspiration (FNA) cytology. METHODS Eleven chest wall swellings were diagnosed as lymphoid neoplasms on FNA over a period of 15 years (January 2000-December 2014). The age of patients ranged from 19 to 73 years (median, 46). The male-to -emale ratio was 7:4. Ten cases had an anterior or lateral chest wall mass, and one swelling was in the scapular region. Six cases had concurrent lymphadenopathy, and one had bone involvement. The FNA smears were reviewed and classified under WHO Classification of Hematopoietic Neoplasms. The histopathological diagnoses were available in eight cases. RESULTS The preliminary cytodiagnoses in 11 cases of chest wall lymphoid neoplasms were anaplastic large cell lymphoma (ALCL) in two cases, and ALCL/malignant melanoma, ALCL/T-cell-rich-B-cell lymphoma (TCRBCL)/Hodgkin's lymphoma (HL), plasmacytoma/neuroendocrine carcinoma, Hodgkin's lymphoma, small cell NHL/CLL, NHL, suggestive of NHL, post-transplant peripheral T-cell lymphoma (PTCL), and a malignant plasma cell tumour in one case each. The reviewed cytodiagnoses of lymphoid neoplasms were as follows: ALCL ( five cases), centroblastic lymphoma (two cases), and small cell lymphoma/CLL, post-transplant peripheral T-cell lymphoma, Hodgkin's lymphoma and plasmacytoma (one case each). Histopathological diagnoses available in eight cases confirmed the presence of lymphoid neoplasms. CONCLUSION A variety of lymphoid neoplasms involved the chest wall, and among them, ALCL was a common form.

Abstract
Human immunodeficiency virus (HIV) is a significant public health issue in Papua New Guinea (PNG). After heterosexual transmission (90%), the second most common route of transmission is vertically from mother to child (3.5%). Before the introduction of molecular methods of HIV testing in PNG, diagnosing exposed infants was problematic because there were no reliable assays available for accurate early infant HIV detection. This study aimed to validate and assess a global gold standard for virological early infant HIV diagnosis in PNG: the AMPLICOR HIV DNA v1.5 assay (Roche) using dried blood spot (DBS) specimens. The assay was validated in three ways: by testing well-characterized DBS and kit controls and by blinded retesting of 42 patient specimens. The assay was further investigated by comparison with a serological assay. The results indicated that the assay was robust and highly reproducible using DBS and kit controls, with 100% sensitivity and specificity. Of the 42 infant DBS specimens that were retested blindly, 100% of the test results were concordant with diagnostic results. Among the 42 infant specimens tested with the Amplicor HIV DNA v1.5 assay we found that 33% of infants (n = 14) were HIV PCR positive and 67% (n = 28) negative. The earliest point of HIV detection established for this study was three months of age. This pilot study indicates that HIV-infected infants in PNG can be effectively diagnosed using virological testing and can thus be started earlier on treatment than was previously possible with serological testing.

Abstract
The ability to manage inventories of carbon, tritium, and high-Z elements in fusion plasmas depends on means for effective dust removal. A dust conveyor, based on a moving electrostatic potential well, was tested with particles of tungsten, carbon, glass, and sand. A digital microscope imaged a representative portion of the conveyor, and dust particle size and volume distributions were derived before and after operation. About 10 mm(3) volume of carbon and tungsten particles were moved in under 5 s. The highest driving amplitude tested of 3 kV was the most effective. The optimal driving frequency was 210 Hz (maximum tested) for tungsten particles, decreasing to below 60 Hz for the larger sand particles. Measurements of particle size and volume distributions after 10 and 100 cycles show the breaking apart of agglomerated carbon and the change in particle distribution over short timescales (<1 s).

Abstract
BACKGROUND Heart failure is a growing health issue and is associated with significant mortality risk. Device therapy is efficacious in preventing sudden death in patients with heart failure; however, this evidence comes from rigorous clinical trials. It is unclear how device therapy is utilized in 'real-world' practice. The primary objective was to characterize patterns of device use in patients with heart failure at risk of sudden death and to identify barriers to guideline-driven prescription of implantable cardioverter-defibrillators. METHODS We report a cross-sectional study of patients attending general cardiology clinic over a 3-month period. RESULTS Of 1003 consecutive patients attending the cardiology clinic, 176 had heart failure. Of these, 66 were potentially eligible for device therapy, but only 16 of these had actually undergone device implantation. Potentially eligible non-recipients were older (P < 0.001), more likely to have ischaemic cardiomyopathy (P= 0.002), less likely to be prescribed spironolactone (P= 0.005) or warfarin (P= 0.02), and less likely to have a widened QRS > 120 ms (P= 0.005). There was a high prevalence of underuse of evidence-based pharmacotherapies among patients with heart failure. CONCLUSION There is substantial underuse of device therapy in patients with heart failure. Strikingly, whereas patients with symptoms of heart failure were more likely to receive a device, those being managed for ischaemic heart disease were not. There is also a high prevalence of failure to prescribe evidence-based pharmacotherapy in a tertiary hospital general cardiology clinic. This may be explained in part by the lack of a patient database to record treatment contraindications and to alert clinicians to possible gaps in patient therapy.

Abstract
We compared the time taken to perform cricothyroidotomy on a manikin to that on a medium fidelity simulator, to assess the effect of psychological stress and time pressure on performance. Seventy anaesthetists participated in this randomised cross-over study. Fifty-four (77%) anaesthetists took longer on the simulator, with the mean (SD) time taken to perform the procedure on the manikin and simulator 34 (18) and 48 (11) s, respectively (p < 0.001). Anaesthetists with more experience performed the procedure more quickly on both manikin and simulator. We conclude that psychological stress and time pressure in real-life scenarios can affect the performance of cricothyroidotomy.

Abstract
Intracardiac blood cysts are thin-walled congenital cysts located in the endocardium and are seen predominantly in infants. They are rare in adults and are typically asymptomatic. However, complications such as valve dysfunction and left ventricular outflow tract obstruction have been reported in adults. We report a 42-year-old woman who developed an embolic stroke in association with intracardiac blood cysts. To the best of our knowledge, this is the first case report of intracardiac blood cysts manifesting as an embolic stroke.
