Aim:To describe the birth prevalence, temporal trends, and clinical outcomes of twins, triplets, or quadruplets with cerebral palsy (CP).Method:This was a cross-sectional study using data for twins, triplets, and quadruplets with prenatally or perinatally acquired CP and pooled from the Surveillance of Cerebral Palsy in Europe network (born 1992–2009) and Australian Cerebral Palsy Register (born 1993–2009). Children were at least 4 years old at time of registration. Children born in regions with population ascertainment and available denominator data were included in prevalence calculations (n=1033 twins, 81 triplets, and 11 quadruplets). Clinical data from children registered in all participating registers were described, including 2163 twins (56% male), 187 triplets (59% male), and 20 quadruplets (45% male).Results:The birth prevalence of CP was higher with increasing plurality (twins 6.5 per 1000 live births [95% confidence interval {CI} 6.1–6.9], triplets 17.1 [95% CI 13.6–21.2], quadruplets 50.7 [95% CI 25.6–88.9]); however, prevalence by gestational age was similar across all pluralities. Between 1992–1994 and 2007–2009, prevalence of CP among twins declined (p=0.001) but prevalence of CP among triplets did not change significantly over time (p=0.55). The distributions of Gross Motor Function Classification System, epilepsy, and impairments of intellect, vision, and hearing were similar regardless of plurality.Interpretation:The data combined from two CP register networks indicated that triplets and quadruplets had increased risk of CP compared to twins. The higher prevalence of CP in triplets and quadruplets is due to their higher risk of preterm birth. Prevalence of CP among twins significantly declined in Europe and Australia. Clinical outcomes were similar for all multiple births.

- Abstract
Automated furrow irrigation systems have been successfully installed and operated on 160 ha of furrow irrigation, on three farms located across the Burdekin sugarcane growing region. The once labour intensive manual irrigation management has been transformed by allowing growers to control, schedule and monitor the behaviour of the pumps, pipeline and valves remotely from a computer, tablet or smartphone. Significant reductions of energy, water, labour and travel associated with irrigation management were seen across all three, large-scale demonstration sites. Reduced labour and travel was seen at each site, with one site registering an annual saving of at least 11,000 km travel. At two of the sites, reduced water usage of around 10% of annual usage was obtained and corresponded to a direct saving in water costs; and for one of these sites, the reduced water usage directly results in a reduced energy cost, while for the other, offers the potential to sell the saved water on the open market. Irrigation events can be scheduled to occur when they are required or to suit off peak electricity tariffs rather than when they suit labour availability. All three farmers recognised the quality of life improvements, and notably their ability to have more time for their family and improved sleeping habits. While assessing improvements to off-site impacts was not part of the project, they are expected as a direct result of the reduction in excess irrigation flowing through to a reduction of irrigation-induced run-off and/or deep drainage and the dissolved agri-chemicals it may contain.

- Abstract
TPC Limited’s management is considering the installation of a molasses-based distillery to be attached to their existing sugarcane factory, which is located to the south of Moshi, Tanzania. The main issue of investigation relates to developing an understanding of the potential impacts of vinasse application, and in particular the addition of potassium, K, to sugarcane fields, some of which are saline-sodic and most are already potassium-rich. The intention is for vinasse to be applied to sugarcane fields across the estate, via the irrigation network, utilising water from a number of sources. Irrigation water, with highly variable quality, is mainly sourced from the Kikafu River, Kikuletwa River, and groundwater reserves. Other important factors that needed to be considered are the potassium (K) rich soils, existing salinity and/or sodicity of some fields, and the depth to groundwater as well as its quality. A comprehensive international literature review along with data supplied by TPC Ltd, was used to parameterise appropriate models to determine the impact of vinasse application, at 0.5% and 2.0%, over both the short (5, 10 and 15 years) and long term (100 years). To represent the range of irrigation water utilised across the estate, the vinasse was diluted with three differing qualities. Applying vinasse, at these concentrations, is expected to increase pH of all soils to approximately 8.5, which would exacerbate the effect of ESP/ECR due to the precipitation of alkaline calcium carbonate. At these concentrations, the vinasse is expected to have a minimal, and manageable, impact on structural stability when using the good quality river water. However the use of ‘median’ quality irrigation water will have mixed impacts depending on the soil. For soils, e.g. Cambisols, Luvisols and Plinthosols, which are predicted to have reductions in hydraulic conductivity, the addition of calcium (Ca), typically from gypsum and potentially supplemented by press mud, could be used

- Abstract
Targets for improvements in water quality entering the Great Barrier Reef (GBR) have been set through the Reef Water Quality Protection Plan (Reef Plan). To measure and report on progress towards the targets set a program has been established that combines monitoring and modelling at paddock through to catchment and reef scales; the Paddock to Reef Integrated Monitoring, Modelling and Reporting Program (Paddock to Reef Program). This program aims to provide evidence of links between land management activities, water quality and reef health. Five lines of evidence are used: the effectiveness of management practices to improve water quality; the prevalence of management practice adoption and change in catchment indicators; long-term monitoring of catchment water quality; paddock & catchment modelling to provide a relative assessment of progress towards meeting targets; and finally marine monitoring of GBR water quality and reef ecosystem health. This paper outlines the first four lines of evidence. (C) 2011 Elsevier Ltd. All rights reserved.

Background/Objectives:Nonglycemic factors like iron deficiency (ID) or anemia may interfere with classification of diabetes and prediabetes using hemoglobin A1c (HbA1c). However, few population-based studies of diabetes in areas with endemic ID/anemia have been conducted. We aimed to determine how mutually exclusive categories of ID alone, anemia alone and iron-deficiency anemia (IDA) were each associated with prediabetes and diabetes prevalence using fasting blood glucose (FBG) versus HbA1c in a population-based study of adults with endemic ID/anemia.Subjects/Methods:We used data from the China Health and Nutrition Survey, a longitudinal, population-based study across 228 communities within nine provinces of China. This analysis included 7308 adults seen in the 2009 survey aged 18–75 years. We used descriptive and covariate-adjusted models to examine relative risk of prediabetes and diabetes using FBG alone, HbA1c alone, HbA1c and FBG, or neither (normoglycemia) by anemia alone, ID alone, IDA or normal iron/hemoglobin.Results:Approximately 65% of individuals with diabetes in our sample were concordantly classified with diabetes using both FBG and HbA1c, while 35% had a discordant diabetes classification: they were classified using either FBG or HbA1c, but not both. Fewer participants with ID alone versus normal iron/hemoglobin were classified with diabetes using HbA1c only. From covariate-adjusted, multinomial regression analyses, the adjusted prevalence of prediabetes using HbA1c only was 22% for men with anemia alone, but 13% for men with normal iron/hemoglobin. In contrast, the predicted prevalence of prediabetes using HbA1c only was 8% for women with ID alone, compared with 13% for women with normal iron/hemoglobin.Conclusions:These findings suggest potential misclassification of diabetes using HbA1c in areas of endemic ID/anemia. Estimating diabetes prevalence using HbA1c may result in under-diagnosis in women with ID and over-diagnosis in men with anemia.

Aims/hypothesisThe purpose of this study was to examine the association between urbanisation-related factors and diabetes prevalence in China.MethodsAnthropometry, fasting blood glucose (FBG) and community-level data were collected for 7,741 adults (18–90years) across 217 communities and nine provinces in the 2009 China Health and Nutrition Survey to examine diabetes (FBG ≥7.0mmol/l or doctor diagnosis). Sex-stratified multilevel models, clustered at the community and province levels and controlling for individual-level age and household income were used to examine the association between diabetes and: (1) a multicomponent urbanisation measure reflecting overall modernisation and (2) 12 separate components of urbanisation (e.g., population density, employment, markets, infrastructure and social factors).ResultsPrevalent diabetes was higher in more-urbanised (men 12%; women 9%) vs less-urbanised (men 6%; women 5%) areas. In sex-stratified multilevel models adjusting for residential community and province, age and household income, there was a twofold higher diabetes prevalence in urban vs rural areas (men OR 2.02, 95% CI 1.47, 2.78; women, OR 1.94, 95% CI 1.35, 2.79). All urbanisation components were positively associated with diabetes, with variation across components (e.g. men, economic and income diversity, OR 1.42, 95% CI 1.20, 1.66; women, transportation infrastructure, OR 1.18, 95% CI 1.06, 1.32). Community-level variation in diabetes was comparatively greater for women (intraclass correlation [ICC] 0.03–0.05) vs men (ICC ≤0.01); province-level variation was greater for men (men 0.03–0.04; women 0.02).Conclusions/interpretationDiabetes prevention and treatment efforts are needed particularly in urbanised areas of China. Community economic factors, modern markets, communications and transportation infrastructure might present opportunities for such efforts.Electronic supplementary materialThe online version of this article (doi:10.1007/s00125-012-2697-8) contains peer-reviewed but unedited supplementary material, which is available to authorised users.

- Abstract
Background: Sleep-disordered breathing (SDB; including stridor and sleep apnea syndromes) is frequent in multiple system atrophy (MSA), but the immediate effect of continuous positive airway pressure (CPAP) therapy is incompletely determined., Objective: We sought to evaluate the acute effect and safety of CPAP therapy on SDB and sleep architecture, as well as the clinical characteristics of nonresponders to CPAP therapy., Methods: The measures of 63 consecutive patients with MSA who underwent a video-polysomnography during two consecutive nights (a first night in ambient air, a second night with or without CPAP, depending on the presence of SDB and availability of CPAP) in routine care were retrospectively collected. Linear mixed models assessed the two-night change in sleep and respiratory measures, comparing those with and without the CPAP therapy on the second night., Results: SDB was frequent and mainly associated with the cerebellar phenotype. The introduction of CPAP had immediate benefits, including the normalization of the apnea-hypopnea index and a resolution of stridor in more than two-thirds of the cases, decreased arousal index, and increased rapid eye movement sleep. CPAP therapy was well tolerated, and only two patients had emergent central apneas. Nonresponse to CPAP was generally associated with more severe motor disease., Conclusions: CPAP seems a well-tolerated and effective therapy in patients with MSA and SDB in the short term. This treatment shows remarkable immediate benefits by objectively improving both respiratory disturbances and sleep architecture. © 2024 The Author(s).

- Abstract
Aim: This exploratory study evaluates rating scale usage by experts from the European Reference Network for Rare Neurological Diseases (ERN-RND) for paediatric MD, considering factors like diagnosis, intellectual disability, age, and transition to adult care. The aim is to propose a preliminary framework for consistent application., Methods: A multicentre survey among 25 ERN-RND experts from 10 European countries examined rating scale usage in paediatric MD, categorizing MD into acute, non-progressive, and neurodegenerative types. Factors influencing scale choice and the transition to adult care practices were analysed. A comprehensive literature search was conducted to identify the earliest age of application of these scales in paediatric patients., Results: The study identifies various rating scales and establishes their usage frequencies for different MDs. Experts highlighted the need for standardized scales and proposed preliminary evaluation strategies based on clinical contexts. Challenges in applying scales to young, non-cooperative patients were acknowledged., Interpretation: The study recommends developing standardized rating scales for paediatric MDs to improve evaluations and data collection. It suggests potential scales for specific clinical scenarios to better evaluate disease progression. Comprehensive, patient-centred care remains crucial during the transition to adult care, despite the identified challenges. This exploratory approach aims to enhance patient outcomes and care., Competing Interests: Declaration of competing interest We hereby affirm that all authors involved in the preparation of this manuscript declare no conflicts of interest.

- Abstract
Integrating weather forecasts into decision support systems empowers farmers to optimise irrigation schedules, thereby boosting crop yields and conserving water. However, inaccurate forecasts can jeopardise productivity and irrigation efficiency. This study combines a crop model with a stochastic pseudo-weather forecast algorithm to: (1) determine the reliability needed in a weather forecast algorithm for effective irrigation management; and (2) assess the impact of weather forecast reliability on the productivity and environmental footprint of various maize cropping systems across diverse climates. It employs the Next Generation of Agricultural Production Systems sIMulator (APSIM NextGen) to simulate maize growth at eleven locations representing diverse climates globally. Various planting schedules, soil types, irrigation systems, and nitrogen availability levels were considered to examine the effects of perfect and imperfect weather forecasts. The findings underscore the potential of integrating weather forecasts into irrigation management for enhanced productivity and sustainability. High-confidence forecasts and longer lead times increase yields (up to 11 %) and improve sustainability outcomes, particularly in wetter climates and for conditions with low nitrogen availability. Conversely, when the accuracy of forecasts is low, forecast-driven irrigation management may lead to yield reductions compared to a baseline system, especially in drier climates (up to 26 % reduction), necessitating tailored management strategies. Soil type and farmer's risk tolerance further influence the effectiveness of forecast-driven irrigation management, emphasising the need for context-specific approaches. By understanding and leveraging the interconnected impacts of weather forecasts on yield, water use efficiency, nitrogen loss, and greenhouse gas emissions, farmers can optimise productivity while minimising environmental impacts., Competing Interests: Declaration of competing interest Authors submitting this manuscript to Science of The Total Environment declare that there are no conflicts of interest that could inappropriately influence, or be perceived to influence, the work reported in this paper., (Copyright © 2024 The Authors.

Attard S, Valdez-Symonds S, Valdez-Symonds S, Iles A, and Maclennan F
- Abstract
The introduction of new legislation in 2006 brought about changes to the way citizenship applications were considered in the UK. Over the intervening years, several hundred children born in the UK have been denied British citizenship as a result of changes to the 'good character' requirement in the legislation - namely its extension to cover all those aged 10 years or older applying for citizenship, including individuals who were born in the UK. As a result of the formulaic way in which this requirement is assessed, citizenship can be denied on the basis of historical patterns of behaviour or offending from childhood. This article will consider whether the current approach to assessment of character in the context of applications for British citizenship is meaningful or appropriate, given developments in our understanding of normative psychological and neurological development and also the impact of psychosocial adversity, trauma, and broader psychopathological or neurodevelopmental conditions.

- Abstract
The ongoing battle against viral pandemics continues, with the possibility of future outbreaks. The search for effective antiviral compounds that can combat a diverse range of viruses continues to be a focal point of research. This study investigated the efficacy of two natural antimicrobial peptides (AMPs) (lactoferricin and LL-37), two synthetic AMPs (melimine and Mel4), and nine AMP mimics (758, 1091, 1096, 1083, 610, NAPL, 3-BIPL, 4-BIPL, and Sau-22) against influenza A virus strains H1N1 and H3N2, human adenovirus 5 (HAdV-5), and murine norovirus 1 (MNV-1). These compounds were tested using virus pre-treatment, cell pre-treatment, or post-cell entry treatment assays, electron microscopy, and circular dichroism (CD), alongside evaluations of cytotoxicity against the host cells. After virus pre-treatment, the AMP mimics 610 and Sau-22 had relatively low IC
50 values for influenza strains H1N1 (2.35 and 6.93 µM, respectively) and H3N2 (3.7 and 5.34 µM, respectively). Conversely, natural and synthetic AMPs were not active against these strains. For the non-enveloped viruses, the AMP Mel4 and mimic 1083 had moderate activity against HAdV-5 (Mel4 IC50 = 47.4 µM; 1083 IC50 = 47.2 µM), whereas all AMPs, but none of the mimics, were active against norovirus (LL-37 IC50 = 4.2 µM; lactoferricin IC50 = 23.18 µM; melimine IC50 = 4.8 µM; Mel4 IC50 = 8.6 µM). Transmission electron microscopy demonstrated that the mimics targeted the outer envelope of influenza viruses, while the AMPs targeted the capsid of non-enveloped viruses. CD showed that Mel4 adopted an α-helical structure in a membrane mimetic environment, but mimic 758 remained unstructured. The diverse activity against different virus groups is probably influenced by charge, hydrophobicity, size, and, in the case of natural and synthetic AMPs, their secondary structure. These findings underscore the potential of peptides and mimics as promising candidates for antiviral therapeutics against both enveloped and non-enveloped viruses.- Published

- Abstract
A seven-year-old healthy female Chow Chow was referred for pregnancy monitoring. Ultrasonography was used to evaluate all pregnancy and fetus parameters, and they were found to be normal. During the examination of the 42 day pregnant bitch, an unusual mass was seen in a fetus's heart. This fetus had a cardiac frequency of 273-300 beats, while the others had heart rates of 220-240 beats. Natural vaginal birth occurred at 63 days pregnant: the first two puppies were stillborn but perfectly formed, and the other three were alive and had optimal APGAR. In one of two deceased puppies, an unusual, reddish, smooth mass occupying the space in the heart was found through necroscopy. The organ was submitted for histological examination. Histopathology, immunohistochemical, and histochemical analyses all indicated a cardiac tumor with increased Purkinje cells. This type of tumor has been described in infants, swine, bearded seals, and deer but never in fetuses and neonates of dogs. To our knowledge, this is the first such case reported in veterinary medicine.

- Abstract
The development of potent antiviral agents is of utmost importance to combat the global burden of viral infections. Traditional antiviral drug development involves targeting specific viral proteins, which may lead to the emergence of resistant strains. To explore alternative strategies, we investigated the antiviral potential of antimicrobial peptidomimetic compounds. In this study, we evaluated the antiviral potential of 17 short anthranilamide-based peptidomimetic compounds against two viruses: Murine hepatitis virus 1 (MHV-1) which is a surrogate of human coronaviruses and herpes simplex virus 1 (HSV-1). The half-maximal inhibitory concentration (IC
50 ) values of these compounds were determined in vitro to assess their potency as antiviral agents. Compounds 11 and 14 displayed the most potent inhibitory effects with IC50 values of 2.38 μM, and 6.3 μM against MHV-1 while compounds 9 and 14 showed IC50 values of 14.8 μM and 13 μM against HSV-1. Multiple antiviral assessments and microscopic images obtained through transmission electron microscopy (TEM) collectively demonstrated that these compounds exert a direct influence on the viral envelope. Based on this outcome, it can be concluded that peptidomimetic compounds could offer a new approach for the development of potent antiviral agents.- Published

- Abstract
The gonadotropin-releasing hormone (GnRH) stimulation test is used to investigate testicular production of testosterone (T) when performing a breeding soundness examination. In male dogs with fertility problems, the prostate should also be investigated as prostatic conditions may frequently lower semen quality. Serum concentrations of canine prostatic-specific esterase (CPSE) increase in dogs with benign prostatic hyperplasia (BPH). When performing a breeding soundness examination in a male dog, GnRH administration is frequently done at the beginning of the process and then both T and CPSE are assayed on the same serum sample collected 1 h following the GnRH injection. The aim of this study was to assess whether or not the administration of GnRH may alter CPSE concentrations in dogs with a healthy prostate. Twenty-eight client-owned intact adult male dogs were included in the study. Following a 7-day sexual rest all male dogs underwent a clinical examination and an ultrasonographic examination of the prostatic gland. Prostatic size and parenchyma of every tested dog were evaluated by ultrasonography to assess prostatic conditions. Two different GnRH stimulation protocols were used, A = gonadorelin 50μg/dog SC (n = 15) and B = buserelin 0.12 μg/kg IV (n = 13). T and CPSE concentrations were measured before and 1 h after GnRH administration by a laser-induced fluorescence analysis. Buserelin and gonadorelin were equally effective in causing a significant increase in serum T concentrations in the post GnRH sample. When considering the 28 dogs together, CPSE concentrations did not change following the stimulation test with either GnRH compound; however, in 4/28 cases, the post GnRH value was markedly increased to values compatible with a diagnosis of BPH. There was no difference in the action of buserelin or gonadorelin in causing an increase in serum T concentrations. CPSE secretion was increased in approximately 15% of dogs treated with either buserelin or gonadorelin. Therefore, whenever performing diagnostic testing in intact male dogs, CPSE should not be assayed on a post-GnRH serum sample., (© 2023 Wiley-VCH GmbH. Published by John Wiley & Sons Ltd.)

- Abstract
Importance: Disorders of the autonomic nervous system are relatively common and have a significant impact on quality of life, offer very subtle diagnostic clues, and often mimic other disease processes, including certain psychiatric disorders. Pharmacologic treatment for psychiatric conditions in this group of patients can also be complicated by the pathophysiology of the various syndromes. Postural orthostatic tachycardia syndrome (POTS) is the final common pathway of a heterogenous group of underlying disorders that display similar characteristics., Observations: The current literature regarding the association between POTS and psychiatric conditions was reviewed. The literature showed an increased prevalence of mild/moderate depression and sleep disturbance in this population. Also, when psychiatric disorders occur in patients with POTS, clinicians may face challenges with regard to selecting appropriate psychopharmacologic interventions., Conclusions and Relevance: This review provides an evidence-based approach to treating common psychiatric conditions in those who suffer from POTS, with a particular emphasis on side effects that may worsen the associated symptoms. A list of the classes of psychopharmacologic treatment with a focus on adverse effects on heart rate and blood pressure is included, as is a case vignette of a patient with complex comorbid psychiatric conditions. It is of significant value to highlight the complexities associated with POTS; to raise awareness of the disorder, particularly in the context of psychiatric comorbidities; and to disseminate evidence-based information to aid clinicians in making informed medication choices with their patients., (© Copyright 2023 Physicians Postgraduate Press, Inc.)

- Abstract
Vitamin C deficiency resulting in scurvy, is considered to be a rare nutritional disorder in developed countries, thus leading to underdiagnosis with exposure to unnecessary investigations and delay in appropriate treatment. The wide myriad of clinical signs and symptoms with which vitamin C deficiency can present (including haematological, musculoskeletal and vague constitutional symptoms that overlap with other common medical conditions), also contributes to this diagnostic challenge. Despite scurvy being habitually thought to be present in children with neurodevelopmental conditions such as autism spectrum disorder, other important at-risk groups that frequently tend to be forgotten include children with persistent fussy eating behaviour, and children with abnormal vitamin C metabolism. We hereunder present a case of a 10-year-old boy who presented to an acute general hospital for further investigation with gait disturbance. The lack of detailed nutritional assessment on presentation in the first instance led to a missed diagnosis of vitamin C deficiency, thus exposing the child to a wide array of unnecessary investigations and treatments. The added perplexity to the case resulting from false positive results of investigations performed as part of this child's workup, is also discussed.

- Abstract
Pyometra is a common uterine disease of dogs and cats, typical of the luteal phase. Traditionally, ovariohysterectomy was considered the elective treatment for pyometra, but in some cases, such as breeding subjects or patients with a high anesthesiologic risk, medical treatment is preferred. Aglepristone is a progesterone receptor blocker and its use proved to be effective for the medical treatment of pyometra in bitches and queens. The aim of this work is to report the effectiveness, in the feline species, of a modified aglepristone administration protocol. Five intact queens were referred to veterinary care centers for pyometra. Aglepristone (15 mg/kg) was administered at D0, D2, D5, and D8, as described by Contri and collaborators for dogs. An antibiotic treatment (marbofloxacin, 3 mg/kg) was associated, and uterine conditions were checked with regular ultrasonographic exams. The uterus returned to its normal condition 10 days after starting the treatment and no adverse effects were reported. After treatment, three queens had an uneventful pregnancy. Even if the treated group was restricted and homogeneous, the proposed modified protocol proved to be useful and promising for the medical treatment of pyometra in cats; further studies are planned to verify its effectiveness in the long-term prevention of recurrence.

- Abstract
Brugada syndrome (BrS) presents with a characteristic electrocardiogram (ECG) and is associated with sudden cardiac death. Until now, prolongation of QTc interval and its association with Torsade de Pointe and possible fatal arrhythmia have been the focus of routine baseline ECGs before prescribing psychotropic medication. A semi-systematic literature review was conducted using PubMed. The terms 'Brugada', 'Brugada Syndrome' AND 'psychotropic' 'antipsychotic' 'antidepressant' 'mood stabilisers' 'clozapine' 'Tricyclic Antidepressants' 'Lithium' were searched. From a search that delivered over 200 articles, 82 articles were included. Those that included details around causative medication, doses of medication and where clear timeline on drug cause were included. Where clarification was needed, the manufacturer of the medication was contacted directly. Psychotropic medication can be associated with BrS, Brugada phenocopy or unmasking of BrS, in overdose or in normal doses. Our results include a table summarising a number of psychotropic overdoses that led to BrS unmasking. Routine screening for BrS in patients before prescribing psychotropic medication is a natural extension of the baseline ECG currently routinely done to rule out QTc prolongation. Psychiatrists need to invest in ensuring better skills in interpreting ECGs and work closer with cardiologists in interpreting ECGs., Competing Interests: Conflict of interest statement: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s), 2022.)

- Abstract
Penile varicose veins are a rare lesion described in human medicine. A seven-year-old intact Akita inu male dog presented with a red penile neoformation. It was further referred for a specialist andrological examination. During the visit, ultrasonography of genital apparatus and cytology of the penile lesion were performed. A suspected neoformation of vascular origin was observed on ultrasonography. Cytology was inconclusive as composition of the sample revealed blood elements only. The neoformation was surgically removed and the excised sample was submitted for the histological examination, which revealed an anomalous varicose dilatation of the venous vascular structures. In human medicine, varicose veins are part of the spectrum of chronic venous disease and include spider telangiectasia, reticular veins, and true varicosities. Reports of penile localization of varicose veins is rare in human medicine and, to the best of our knowledge, it has never been reported in veterinary medicine.

- Abstract
Background: Subtotal tonsil surgery (tonsillotomy) remains a controversial procedure. We aimed to document bleeding rates and return to normal activity for total versus subtotal tonsil surgery in the paediatric population., Methods: A 10-year cohort of 608 children from a single-surgeon series was analysed. Bleeding events were classified using the Flinders modification of the Stammberger criteria. Return to normal activity was defined as normal diet and return to childcare/school., Results: A total of 8.3% of tonsil procedures and a subtotal of 1.8% of procedures had some kind of bleeding episode (P < 0.01; odds ratio 3.2; 95% confidence interval (CI) 1.3-7.6). When blood-stained sputum (type A bleed) was excluded, this dropped to 2.5% versus 0.3%, respectively (P < 0.05; odds ratio 8.5; 95% CI 1.2-96.0). Return to normal activities occurred at a mean of 11.1 (95% CI 9.7-12.5) versus 4.6 (95% CI 4.0-5.3) days, respectively (P < 0.0001)., Conclusion: In this 10-year single surgeon series, subtotal tonsillectomy or 'tonsillotomy' was associated with a significant reduction in both prevalence and severity of bleeding, in addition to a more rapid return to normal activities when compared to total tonsillectomy., (© 2020 Royal Australasian College of Surgeons.)

- Abstract
Introduction and Aims: Transcatheter aortic valve implantation (TAVI) is an alternative procedure for patients with symptomatic aortic stenosis unfit for open heart surgery. Notwithstanding the safer profile, TAVI can still result in serious complications including acute kidney injury (AKI)., Materials and Methods: We conducted a single-center retrospective study to investigate the incidence of AKI following TAVI, identify any predictors, and assess the impact on patient survival., Results: A total of 104 patients underwent TAVI at a mean age of 76.7 ± 7.2 years. AKI occurred in 35.9% of patients; 26.2% stage 1, 5.8% stage 2, and 3.9% stage 3. These patients had higher incidence of chronic kidney disease (CKD) (37.8 vs. 18.2%; p = 0.035), higher median EuroSCORE-II (4.2, IQR: 5.7 vs. 2.7, IQR: 3.6; p = 0.019), longer hospital stay (6 days, IQR: 7 vs. 5 days, IQR: 3; p = 0.016), and higher all-cause mortality (35.1 vs. 12.1%, p = 0.01) compared to patients without AKI. None of the patient mortality was directly related to the TAVI-AKI event. EuroSCORE-II (OR: 1.19, CI: 1.05 - 1.37, p = 0.009) and CKD (OR: 2.74, CI: 1.10 - 6.82, p = 0.03) were established as independent predictors for AKI. Cumulative survival was lower in patients with AKI (log-rank; χ
2 = 6.43, p = 0.011). AKI was established as a hazard for mortality (HR: 2.97, CI: 1.23 - 7.19, p = 0.016)., Conclusion: More than a third of patients undergoing TAVI developed AKI. These had significantly higher incidence of CKD, higher EuroSCORE-II, higher all-cause mortality, and longer hospital stay. Finally, EuroSCORE-II and CKD were established as independent predictors for AKI and can therefore be used for risk stratification. .- Published

- Abstract
Purpose: To evaluate the perception and 5-year application of anatomic side markers (ASMs) by radiographers in Malta., Methods and Materials: Phase 1 involved a longitudinal, retrospective observation of a stratified sample of radiographs over 5 years, using a self-designed data record sheet to record features of the placement of ASMs. Phase 2 consisted of a cross-sectional, prospective self-designed questionnaire evaluating the radiographers' perception on the use of ASMs in professional practice., Results: In phase 1, radiographs (n = 500) were selected from 234,105 taken over the 5-year period (error: ±4.38%; 95% confidence level). Four hundred thirty radiographs (86%) had evidence of markers, of which 110 (25.6%) had a pre-exposure marker and 320 (74.4%) had a postprocessed marker. The remaining 14% had no evidence of any markers. Two hundred eighty two (56.4%) of the radiographs had ASMs placed according to recommended guidelines by Ballinger, Frank, and Merrill. In phase 2, most radiographers (84.6%) preferred using postprocessing markers, with 15.4% preferring pre-exposure markers (76.6% of radiographers found applying pre-exposure markers time consuming). Sixty percent (60.5%) of radiographers gave correct answers on use of markers as recommended in the guidelines., Conclusions: Radiographer preference in using postprocessing markers was evident, while the use of pre-exposure markers was seen to be influenced by time of examination, projection executed, and patient positioning. Radiographer awareness and continuous training are recommended., (Copyright © 2016 Canadian Association of Medical Radiation Technologists. Published by Elsevier Inc. All rights reserved.)

- Abstract
Context: The effect of seasons and meteorology on the incidence of nephrolithiasis has been studied in various regions around the globe, but seldom in the Mediterranean., Aims: This retrospective analysis aims at investigating these putative effects in the Maltese Islands, whose climate is typically Mediterranean, followed by a systematic review of the literature., Materials and Methods: Submission rate and chemical composition of all kidney stones after spontaneous passage or surgical removal between January 2009 and December 2011 were analyzed according to seasons and corresponding meteorology., Results: A total of 389 stones were analyzed. A higher stone submission rate was observed in summer compared to winter (31.6% vs. 20.8%, P = 0.0008) and in the warm period compared to the cold period (57.1% vs. 42.9%, P = 0.0001). Significant correlation was established between the monthly number of stones and mean monthly maximum temperature (r = 0.50, P = 0.002), mean monthly temperature (r = 0.49, P = 0.003) and mean monthly Humidex (r = 0.49, P = 0.007). Humidex was found to be an independent predictor for stone submission (β = 0.49, P = 0.007). The majority of stones contained calcium (83.3%), combined with oxalate (77.6%), phosphate (14.7%), and carbonate (2.8%). Some stones (11.8%) contained a mixture of >1 negatively charged molecules. Urate (11.6%), cysteine (4.6%), and ammonium-magnesium-phosphate (0.5%) constituted the rest. There was no association between chemical composition and seasons. Literature review included 25 articles. Higher ambient temperature and warm seasons were the most commonly encountered risk factors for both presentation and etiology of nephrolithiasis., Conclusions: A significant positive correlation was noted between ambient temperature and stone submission rate, which was significantly higher during the warm months in Malta.

Violent offenders with psychopathy present a lifelong pattern of callousness and aggression and fail to benefit from rehabilitation programs. This study presents the first, albeit preliminary, evidence suggesting that some of the structural brain anomalies distinguishing violent offenders with psychopathy may result from physical abuse in childhood., (© 2013 Published by Elsevier Ireland Ltd.)

- Abstract
Objective: To document experiences of childhood maltreatment among violent offenders with antisocial personality disorder (ASPD) distinguishing between those with and without the syndrome of psychopathy (+P and -P), and to determine whether maltreatment is associated with proactive and reactive aggression., Method: The sample included 10 violent offenders with ASPD+P, 15 violent offenders with ASPD-P, and 15 non offenders. All participants completed interviews with the same forensic psychiatrist focusing on physical, sexual, and emotional abuse prior to age 18 using the Early Trauma Inventory. Aggression was assessed using the Reactive-Proactive Questionnaire., Results: Violent offenders with ASPD+P reported significantly more severe childhood physical abuse, but not more sexual or emotional abuse, than violent offenders with ASPD-P and non offenders. Psychopathy Checklist-Revised (PCL-R) scores, but not childhood physical abuse, were associated with proactive aggression. Childhood physical abuse was associated with reactive aggression, as was an interaction term indicating that when both PCL-R scores and childhood physical abuse were high, so was reactive aggression., Conclusions: Among violent offenders, PCL-R scores were positively associated with proactive aggression, while experiences of childhood maltreatment were not. This finding concurs with previous studies of children and adults and suggests that proactive aggression may be a behavioural marker of psychopathic traits. By contrast, childhood physical abuse was associated with reactive aggression, even among violent offenders with high PCL-R scores. This latter finding suggests a strong influence of childhood physical abuse on the development of reactive aggression that persists over the lifespan.

- Abstract
Targets for improvements in water quality entering the Great Barrier Reef (GBR) have been set through the Reef Water Quality Protection Plan (Reef Plan). To measure and report on progress towards the targets set a program has been established that combines monitoring and modelling at paddock through to catchment and reef scales; the Paddock to Reef Integrated Monitoring, Modelling and Reporting Program (Paddock to Reef Program). This program aims to provide evidence of links between land management activities, water quality and reef health. Five lines of evidence are used: the effectiveness of management practices to improve water quality; the prevalence of management practice adoption and change in catchment indicators; long-term monitoring of catchment water quality; paddock & catchment modelling to provide a relative assessment of progress towards meeting targets; and finally marine monitoring of GBR water quality and reef ecosystem health. This paper outlines the first four lines of evidence., (Copyright © 2011 Elsevier Ltd. All rights reserved.)
