Published: June 2021

Nicotinic acid hydrazide and 2,4-dihydoxylbenzaldehyde were condensed at 20 °C to form an acylhydrazone (H3L1) with ONO coordination pattern. The structure of the acylhydrazone was elucidated by using CHN analyzer, ESI mass spectrometry, IR, 1H NMR, 13C NMR and 2D NMR such as COSY and HSQC. Thereafter, five novel metal complexes [Mn(II), Fe(II), Pt(II) Zn(II) and Pd(II)] of the hydrazone ligand were synthesized and their structural characterization were achieved by several physicochemical methods namely: elemental analysis, electronic spectra, infrared, EPR, molar conductivity and powder X-ray diffraction studies. An octahedral geometry was suggested for both Pd(II) and Zn(II) complexes while both Mn(II) and Fe(II) complexes conformed with tetrahedral pyramidal. However, Pt(II) complex agreed with tetrahedral geometry. In vitro antitubercular activity study of the ligand and the metal complexes were evaluated against Mycobacterium tuberculosis, H37Rv, by using micro-diluted method. The results obtained revealed that (PtL1) (MIC = 0.56 mg/mL), (ZnL1) (MIC = 0.61 mg/mL), (MnL1) (MIC = 0.71 mg/mL) and (FeL1) (MIC = 0.82 mg/mL), exhibited a significant activity when compared with first line drugs such as isoniazid (INH) (MIC = 0.9 mg/mL). H3L1 exhibited lesser antitubercular activity with MIC value of 1.02 mg/mL. However, the metal complexes displayed higher cytotoxicity but were found to be non-significant different (P > 0.05) to isoniazid drug.

A origem da heterogeneidade da brotação em regiões de inverno ameno
Authors: Leite Gabriel Berenhauser
Published: June 2021

Sob condições de inverno ameno, espécies frutíferas temperadas sofrem problemas agronômicos resultantes de brotamento e floração heterogêneo. O padrão de evolução da dormência e da brotação de pessegueiro foi estudado usando condições experimentais que forneceram plantas com 1) Condições naturais de inverno em clima temperado (CN), 2) Privação parcial de frio (PPF) e 3) Privação total de frio (PTF). A endodormência das gemas vegetativas foi caracterizada por meio do teste de estacas de gema única. As plantas com privação de frio, tanto parcial, como total, apresentaram evolução da dormência e taxa de brotação alterada em relação as plantas sob CN. Os padrões de brotação dependeram dos padrões de saída da endodormência das gemas, tanto no tempo quanto no espaço. Pelo comportamento observado na evolução da dormência e da brotação, podemos inferir que, em condições de inverno temperado, o gradiente de brotação tem origem na capacidade de crescimento das gemas após a saída da endodormência, enquanto que em condições de privação parcial de frio, a origem está na evolução diferencial da endodormência das gemas ao longo do ramo.

Authors: De Souza Natalia Maria , Marschalek Rubens , Sangoi Luis
Published: June 2021

A temperatura é um dos fatores climáticos mais importantes para o cultivo de arroz. Temperaturas acima de 35ºC limitam a produção deste cereal, podendo acarretar prejuízos irreversíveis à produtividade. A antese é a fase mais sensível do arroz à ocorrência de altas temperaturas. Este trabalho foi conduzido com o objetivo de avaliar o desempenho agronômico e a qualidade de grãos de cinco genótipos (Epagri 109, SCS116 Satoru, SCS121 CL, SCS122 Miura e SC 676), em duas safras agrícolas (2016/17 e 2017/18), correlacionando-os com a temperatura do ar durante a antese e o enchimento de grãos. Avaliaram-se a esterilidade de espiguetas, a produtividade, a massa de 1.000 grãos e aspectos qualitativos de pós-colheita (rendimento de engenho e percentual de gesso). As temperaturas observadas na safra 2016/17 da antese até a colheita foram superiores às observadas na safra 2017/18, apresentando médias de 30,5 e 28,5ºC e temperaturas máximas de 34,3 e 30,9ºC para cada safra, respectivamente. As temperaturas mais elevadas na primeira safra reduziram a produtividade, a massa de 1.000 grãos e o rendimento de engenho. Elas também aumentaram a esterilidade de espiguetas e o percentual de gesso. A linhagem SC 676 apresentou a maior produtividade (13.070 kg ha-1), porém foi o genótipo com pior qualidade de grãos.

Published: June 2021

Dentre as pragas do arroz irrigado em Santa Catarina estão a bicheira-da-raiz, Oryzophagus oryzae (Costa Lima) e Helodytes sp. (ambas Coleoptera: Curculionidae), a lagarta-boiadeira, Nymphula spp. e a noiva-do-arroz, Rupela albinella Cramer (ambas Lepidoptera: Pyralidae), o percevejo-do-grão, Oebalus spp. (Hemiptera: Pentatomidae) e o cascudo-preto, Euetheola humilis (Burmeister) (Coleoptera: Scarabaeidae). A dispersão desses insetos no ambiente é ampla, porém se desconhece a capacidade dos mesmos transporem obstáculos verticais na rota de voo. Assim, foi objetivo desta pesquisa verificar a altura de voo dos insetos-pragas do arroz irrigado. Duas armadilhas luminosas, modelo “Luiz de Queiroz” foram instaladas em uma lavoura de arroz irrigado em Itajaí, SC, sendo uma delas ao nível superior das plantas e a outra a seis metros de altura do solo. No período de setembro de 2014 a dezembro de 2015, as armadilhas foram ligadas diariamente das 16:00 às 9:00h, exceto de maio a agosto de 2015, quando permaneceram desligadas. Todas as espécies citadas alcançaram a altura de voo de 6m e, portanto, são capazes de ultrapassar obstáculos até essa altura. Contudo, apenas O. oryzae e E. humilis voam habitualmente por esse estrato.

Published: June 2021

Os produtos frescais tem importância significativa no âmbito da qualidade e segurança dos alimentos, em função das características desses produtos, especialmente por sua maior suscetibilidade à deterioração e consequente curta vida útil para consumo. Assim, o objetivo deste trabalho foi realizar uma revisão bibliográfica apresentando os aspectos de interesse relacionados à microbiota e conservação de produtos frescais. Para a presente pesquisa foram realizadas revisões bibliográficas na literatura nacional e internacional. Realizou-se uma busca por termos microbiologia, microbiota, produtos frescais, produtos cárneos, produtos lácteos e conservação de produtos crus em um período de busca de março de 2017 à março de 2020. A microbiota apresenta-se bastante variável, principalmente em função da espécie animal a partir da qual se obtém o produto ou a matéria-prima para elaboração de variados produtos derivados frescais. Já os processos de conservação incluem ações no sentido do impedimento de que os micro-organismos cheguem ao produto; da destruição dos micro-organismos e da modificação nas condições ambientais, criando-se outras que impeçam o crescimento microbiano. Nesse sentido, os esforços acerca da obtenção de maior qualidade microbiológica nos produtos frescais devem alcançar toda a cadeia produtiva, e a conservação dos produtos frescais pode complementar a melhoria das condições de viabilidade para o consumo dos mesmos.

O objetivo do trabalho foi estudar o comportamento fenológico do cultivar de cebola Empasc 352 – Bola Precoce quando submetido às diferentes condições climáticas e fotoperiódicas em condições de clima subtropical de Santa Catarina, SC, Brazil. Os tratamentos consistiram de 10 épocas de semeaduras, distanciadas em uma semana, repetidas no período 15/03 à 17/05 em quatro anos. Os resultados revelam que a relação entre as datas de semeadura e a duração em dias até o transplante não é linear, podendo ser representada por um polinômio de segundo grau, onde as últimas datas de semeaduras apresentam um significativo aumento na duração semeadura-transplante. À medida em que as épocas de semeaduras foram postergadas ocorreu uma diminuição do período entre transplante-colheita. A relação entre a duração da fase semeadura-transplante e transplante-colheita foi inversa, ou seja, maiores durações da fase semeadura-transplante menores as fases de transplante-colheita. A data de semeadura foi o principal responsável pela variação da duração do ciclo da cebola. Para cada dois dias de avanço na data de semeadura ocorreu uma postergação na data de transplante em três dias.

Treatment of human immunodeficiency virus(HIV) in cancer patients improves outcomes and reduces transmission of this oncogenic virus. HIV testing rates of cancer patients are similar to the general population (15-40%), despite the association with cancer. Our aim was to increase HIV screening in the Emergency Department(ED) of a comprehensive cancer center through a quality initiative. Testing increased significantly during the intervention (p<0.001; 0.15/day to 2.69/day). Seropositive HIV rate was 1.4% (12/852), with incidence of 0.3%. All patients were linked to care. Incident cases were between 36 and 55 years of age. Barriers encountered included confusion regarding the need for written consent for HIV testing, failure to consider ordering the test, and concerns regarding linkage to care.

Point of care ultrasound (POCUS) has seen steady growth in its use and applications in aiding clinicians in the management of acutely unwell patients. Focused Acute Medicine Ultrasound (FAMUS) is the standard created specifically for Acute Medicine physicians and is endorsed by the Society for Acute Medicine and recognised by the Acute Internal Medicine (AIM) training committee as a specialist skill. In this document we present a curriculum mapping exercise which utilises a ‘knowledge, skills and behaviours’ framework and incorporates the GMC’s ‘Good Medical Practice’ (GMP) domains. We believe this will provide a standard for consideration of integrating focused ultrasound in AIM training programmes, with the aim of ultimately incorporating FAMUS as a core skill for all AIM trainees.
The way healthcare is funded is wrong: it should be linked to deaths as well as age, gender and social deprivation
Authors:   Healthcare Analysis & Forecasting, Worcester, UK., Jones Rodney P , Kellett John ,   Department of Emergency Medicine, Hospital of South West Jutland, Esbjerg, Denmark
Published: June 2021

Background: most spending on health occurs in the last few months of life. This study explored the number of deaths in England and their relationship to healthcare funding. Methods: post hoc analysis Results: the number of deaths range from 3.3 to 15.1/1000/year, and the number of deaths per general practitioner from 5.2 to 27.3/year. Hospital deaths range from 12 to 52/1000 admissions. The correlation between the allocation index used for funding and deaths is not perfect and suggests that some regions may get up to17% less and others 14% more funding than is equitable. Conclusion: there is considerable variation in the prevalence of death throughout England. If healthcare funding considered the local number of deaths it would be more equitable.

Authors:   Clatterbridge Cancer Centre Merseyside, Marshall E
Published: June 2021

Neutropenic Sepsis (NS) is a well recognised treatment complication, typically occurring 7-10 days following cancer cytotoxic chemotherapy. Colleagues in acute medicine will be only too familiar with the scenario of cancer patients that present with fever in the absence of localising signs and symptoms and with a very low yield from microbiological cultures. The incidence and mortality of NS are poorly defined and historically, management guidelines have often been developed in relative isolation from the broader subject of infection and sepsis care. Despite the lack of a clear and pragmatic definition, NICE guidance CG151 (2012) identified suspected NS as a medical emergency requiring prompt empirical broad spectrum antibiotics.

Background: heart rates generated by pulse oximeters and electronic sphygmomanometers in acutely ill patients may not be the same as those recorded by ECG Methods: heart rates recorded by an oximeter and an electronic sphygmomanometer were compared with electrocardiogram (ECG) heart rates measured on acutely ill medical patients. Results: 1010 ECGs were performed on 217 patients while they were in the hospital. The bias between the oximeter and the ECG measured heart rate was -1.37 beats per minute (limits of agreement -22.6 to 19.9 beats per minute), and the bias between the sphygmomanometer and the ECG measured heart rate was -0.14 beats per minute (limits of agreement -22.2 to 21.9 beats per minute). Both devices failed to identify more than half the ECG recordings that awarded 3 NEWS points for heart rate. Conclusion: Heart rates of acutely ill patients are not reliably measured by pulse oximeter or electronic sphygmomanometers.

We sought to assess the impact of renal impairment on acute medical admissions and to identify potential contributory factors to admissions involving renal impairment at presentation. In a prospective cohort study, 29.5% of all acute medical emergency admissions had an eGFR < 60 ml/min/1.73m2 at presentation. Of these, 19.9 % had definite chronic kidney disease and 8.4 % had definite acute kidney injury. Detailed analysis of a random subset of patients with an eGFR <60ml/min/1.73m2 at presentation demonstrated that the major reasons for admission included falls, dehydration and fluid overload. 46% were on diuretics and 53% were on an ACEI or ARB or both. Gastrointestinal disturbance and recent medication changes were common and diuretic use persisted even with diarrhoea or vomiting.

This is a T2 weighted image (T2WI). In T2WI compartments filled with fluid appear brighter (as is the case of the CSF in the lateral ventricles). On the contrary, tissues with a high fat content appear as dark. This T2WI demonstrates layering of debris (figure 2- marked red star) in the occipital horn of the lateral ventricles. In this particular patient, the complete MRI report additionally demonstrated that the debris did not show a high T1 signal, demonstrated diffusion restriction, and a high FLAIR sequence. There was also restricting material observed in the fourth ventricle and the sylvian fissures bilaterally. There were no parenchymal changes or pathological contrast enhancements within the brain tissue. Whilst this appearance could represent blood, the appearance of the debrinous material itself was more in keeping with infective/pus material within the ventricles suggestive of ventriculitis.

Objective: To ensure clinicians can rely on point-of-care testing results, we assessed agreement between point-of-care tests for creatinine, urea, sodium, potassium, calcium, Hb, INR, CRP and subsequent corresponding laboratory tests. Participants: Community-dwelling adults referred to a community-based acute ambulatory care unit. Interventions: The Abbott i-STATTM (Hb, clinical chemistry, INR) and the AfinionTM Analyser (CRP) and corresponding laboratory analyses. Outcomes: Agreement (Bland-Altman) and bias (Passing-Bablok regression). Results: Among 462 adults we found an absolute mean difference between point-of-care and central laboratory analyses of 6.4g/L (95%LOA -7.9 to +20.6) for haemoglobin, -0.5mmol/L (95%LOA -4.5 to +3.5) for sodium, 0.2mmol/L (95%LOA -0.6 to +0.9) for potassium, 0.0mmol/L (95%LOA -0.3 to +0.3) for calcium, 9.0 μmol/L (95%LOA -18.5 to +36.4) for creatinine, 0.0mmol/L (95%LOA -2.7 to +2.6) for urea, -0.2 (95%LOA -2.4 to +2.0) for INR, -5.0 mg/L (95%LOA -24.4 to +14.4) for CRP. Conclusions: There was acceptable agreement and bias for these analytes, except for haemoglobin and creatinine.

Quick radiological diagnosis is often needed in order to allow the clinicians to make a diagnosis. The purpose of this study was to measure examination time for radiology procedures before and after physical integration of a radiology unit in the ED. We retrospectively acquired data from the radiology information system and compared time from referral to end of radiological examination before and after physical integration of the radiology unit in the ED for 19,897 X-ray and 6,940 CT examinations. After integration examination time for X-ray examinations was reduced by 5 to 14 minutes (p<0.001). For CT head and chest examination time was reduced by 7 to 15 minutes (p<0.003) while examination time for CT abdomen was prolonged by 4 minutes (p=0.78).

Acute kidney injury is frequently encountered in patients with malignancy and is associated with prolonged hospitalization, significant morbidity, and increased mortality. Thorough evaluation is required to identify possible contributing factors, which may range from relatively easily reversible pre-renal causes to complex cancer-specific aetiologies. This review will serve as a practical guide for acute care physicians on the acute medical unit to the assessment and initial management of cancer patients presenting with acute kidney injury.
Ambulatory drainage and management of a pleural empyema
Authors: Aujayeb Avinash , Jackson Karl , Johnston Robert
Published: June 2021

A 61 year old male presented to chest clinic with a lung abscess. This ruptured and resulted in an empyema that required a small bore chest drain. Pus started bypassing the drain, spilling out subcutaneously. This was probably due to the impending formation of an empyema necessitans. To stem the flow, a large bore drain was inserted. An ambulatory bag was connected to the end of that drain which enabled outpatient management through the ambulatory care unit over a ten week period. The chest drain stayed in for nine weeks. Risk stratification using the RAPID score was applied. This is a routine medical presentation with well-known and accepted investigations with routine organisms (mixed aerobic and anaerobic microbiota) and treatment with classical broad spectrum antibiotics. The striking feature of the case is that with strict supervision, patient education and motivation, ambulatory management is perfectly feasible and safe.

Background: Positive blood cultures predict mortality. The prognostic value of blood culture performance itself has not been fully defined. Methods: We evaluated medical admissions from 2002-2017. We defined blood culture category as 1) no culture 2) negative culture 3) positive culture. We employed a multivariable logistic regression model to evaluate outcomes. Results: We evaluated 78,568 blood cultures in 106,586 admissions. 30-day in-hospital mortality for no culture was 2.8% (95%CI 2.7, 2.9), culture negative 8.9% (95%CI 8.5, 9.3) and culture positive 16.7% (95%CI 15.5, 17.9). There was significant interaction between blood culture category and illness severity, OR 1.06 (95%CI 1.05, 1.08), and comorbidity, OR 1.09 (95%CI 1.09, 1.10). Conclusion: Performance and results of blood cultures are independently associated with increased mortality.

Aims: To create a profile of Society for Acute Medicine (SAM) Audit and Quality Improvement (A&QI) accepted abstracts from the last seven UK based conferences. Methodology: The profile elements for 380 SAM A&QI abstracts accepted for poster presentation were compiled from their respective conference programme booklets. Abstracts were classified into 30 categories based on key themes. Further sub-categorisation of abstracts was based on secondary detail of the submissions. Data was analysed with Pareto charts. Findings: The majority of submissions were covered by a small representation of themes, with 30% of category themes covering 80% of A&QI abstracts. There is a repetitive trend of theme categories across all the conferences.
