Authors: Ragunathan Kaushik , Chandrasekhar Jayakumar
Published: August 2019

Background: Neonatal seizure management has not changed much in the last 50 years. Neuronal apoptosis in animal models and cognitive impairment in human subjects has been reported with the use of Phenobarbitone. Levetiracetam is advantageous as it is effective, well tolerated and has least drug interactions.Methods: This double blinded, randomized, parallel group, active controlled study was conducted among 66 neonates in the Neonatal intensive care unit of a tertiary care hospital for a period of 18 months. Neonates with seizures fulfilling the inclusion criteria were treated either with Phenobarbitone or Levetiracetam. Seizure control was defined as no seizure activity within 40 minutes of the administration of the first drug. Failure of first line agent was treated with Phenytoin. Neonates were observed for a period of 14 weeks for recurrence of seizure and any serious adverse effects.Results: Effective seizure control was achieved in 64.7% neonates in Levetiracetam group as compared to 31.2% in Phenobarbitone group (p <0.05). Early resumption of breast feeds within 6 hours of therapy was achieved in 73.5% neonates treated with Levetiracetam compared to 31.2% neonates treated with Phenobarbitone (p value = 0.001).Conclusions: Levetiracetam is a promising alternative as first line Anti-epileptic drug in neonates with seizures. Prolonged sedation was the adverse effect noted to Phenobarbitone that made breast feeding and neuro- assessment difficult. No serious adverse effects were seen with Levetiracetam.

Published: August 2019

Background: Double volume exchange transfusion (DVET) for severe unconjugated hyperbilirubinemia has become less common events now days in pediatric practices. But kernicterus is still common in low income country like India. The aim of the study was to determine the clinical profile and outcome in neonates who were treated with DVET.Methods: This was a retrospective study in neonate’s ≥34 weeks of gestation that were treated with DVET for severe neonatal hyperbilirubinemia over a period of four years.Results: In our study, 37 neonates underwent DVET. Male neonates (62.13%) and normal vaginal delivery (NVD) (70.2%) are common. ABO Isoimmunisation was commonest cause (56.75%) of exchange transfusion.  The mean TSBR at pre exchange and Post Exchange were 27.39 ± 5.99mg/dl and 15.16 ± 4.00mg/dl (p<0.05). Ten neonates (27%) among 37 neonates required twice DVET.Thrombocytopenia14 (37.83%); Seizure 5(13.5%) and Hypocalcaemia 3(8.1%) were common complication noted among total 17 (45.94%) neonates. BIND occurred in 15 neonates (40.5%) at the time of admission and seven (18.9%) neonates had persistent neurological abnormality at discharge. Neonate with BIND had early onset of jaundice (44.13±15.37 hours vs. 61.22±28.23hrs, p<0.05), with  higher  pre exchange TSBR value(28.96 ±8.5mg/dl vs. 26.22±3.17mg/dl). Neonates admitted with BIND had higher percentage of persistent encephalopathy (40% vs. 4.5%,p<0.05), abnormal tone (33.3% vs. 4.5%,p<0.05), abnormal feeding (33.3% vs. 4.5%,p<0.05) and abnormal posture (26.6% vs. 0%,p<0.05)  at discharge as compared to those without BIND. No death occurred in this study population.Conclusions: Early detection and aggressive therapy with DVET can prevent neonates from brain injury.

Authors: Donel Jissa
Published: August 2019

Jaundice is a common condition in neonates, occurring in 60% to 84% of late term and term  infants. Phototherapy is considered as a treatment of choice since many years in the management of unconjugated hyperbilirubinemia. Phototherapy is the use of visible light to treat severe jaundice in the neonatal period. Treatment with phototherapy is implemented in order to prevent the neurotoxic effects of high serum unconjugated bilirubin. Different types of phototherapy delivery system are in use. Bili blanket phototherapy uses fiberoptic systems  that reduces or eliminates all of the potential complications of conventional phototherapy and  facilitates establishment of  an enhanced parent-infant bond.

Authors: Akkati Ruchitha Reddy
Published: August 2019

Abiogenic cervical dystonia, the most ordinary form of adult-onset focal dystonia, is elucidated as reflex muscle contractions. Idiopathic cervical dystonia is also called as spasmodic torticollis. The most habitually obliging medications were tetrabenazine (68% of patients upgraded) and anticholinergics (39% upgraded). Clinical manifestations include spinal curvature, local pain, muscle spasm, head-neck tremor and tremor in additional body regions. Antipsychotic drugs induce persistent dystonia. Lymphadenitis particularly refers to lymphadenopathies that are kindled by inflammatory processes. Treatment for lymphadenitis is complete antibiotic course of 10-14 days. A female patient of 14 years old presented with altered sensorium and neck tightness. She was diagnosed with cervical lymphadenopathy with risperidone induced cervical dystonia. She was treated with antibiotics and the patient was relieved from her symptoms by stopping the intake of risperidone for about 2 days.

Published: August 2019

Objetivou-se analisar a percepção ambiental do uso de sistemas agroflorestais na recuperação de reserva legal em Cametá, Pará, propondo a discussão entre o perfil das propriedades, a percepção ambiental dos principais termos do Código Florestal, conhecimento protecionista dos sistemas agroflorestais e regularização ambiental. Foram aplicados questionários semiestruturados com auxílio de entrevista a 50 agricultores em 10 localidades do município, além disso, foi realizado o levantamento dos dados do Cadastro Ambiental Rural dos entrevistados e do total do município. Para conhecer a realidade ambiental foi realizada a análise do desmatamento entre 2006 e 2017. Os resultados apontam que a maioria dos agricultores de Cametá possuem pouco conhecimento a respeito da lei ambiental. Em relação ao Cadastro Ambiental Rural, apenas 32,72% das propriedades rurais encontram-se cadastradas até outubro de 2018 e 80% das propriedades cadastradas necessitam recompor suas reservas legais. Apesar do conhecimento incipiente sobre os sistemas agroflorestais, a falta de recursos financeiros, efetividade da assistência técnica, desconhecimento sobre responsabilidades e obrigações, podem gerar uma grande crise econômica e social com a aplicação de embargos e multas pelo não atendimento ao disposto no Programa de Regularização Ambiental.

Published: August 2019

A pegada hídrica cinza (PHC) é definida como o volume de água doce necessário para diluir poluentes incorporados nas camadas superficiais e subsuperficiais do solo, por meio da emissão de agrotóxicos na produção agrícola. Diante disso, o objetivo com esta pesquisa foi avaliar a pegada hídrica cinza no cultivo de tomate em regiões do semiárido brasileiro. O trabalho foi desenvolvido nos municípios de Parelhas e Equador, ambos localizados no estado do Rio Grande do Norte. Foi realizado um levantamento dos principais poluentes, além das condições ambientais de solo e clima, em seguida, foram utilizados modelos matemáticos para estimar a pegada hídrica cinza. Os agrotóxicos avaliados foram: Evidence, LannateBr, Karate 50 EC, Sportak 450 EC, Sencor 480, Ridomil Gold e Confidor S. O inseticida Ridomil Gold (Clorotalonil) foi considerado bastante ofensivo para a produção de tomate neste estudo, a aplicação do mesmo deve ser evitada, sendo necessário sua substituição por outro que requeira menos água doce para sua diluição. Já os agrotóxicos Lannate BR (Metomil), Karate 50 EC (Lambda-Cialotrina) e Sportak 450 EC (Procloraz) foram os que apresentaram menor exigência de água para diluição.

Published: August 2019

O maracujá amarelo é fruto climatérico que apresenta alta perecibilidade quando armazenado em temperatura ambiente. Assim, objetivou-se avaliar os efeitos do revestimento do amido da entrecasca de mandioca na conservação pós-colheita de maracujás amarelos armazenados em temperatura ambiente. O amido da entrecasca da mandioca foi extraído por decantação e seco. Em seguida, foi utilizado na preparação do revestimento vegetal, através da gelatinização do amido. O experimento seguiu delineamento inteiramente casualizado, com esquema fatorial 4 x 3, com três tratamentos (controle, sem revestimento; e amido como revestimento nas concentrações de 1%, 2% e 3%) e três tempos de amostragem (0, 7 e 10 dias). Nesse período realizaram-se análises físicas (coloração da casca, perda de massa e rendimento de suco) e químicas (sólidos solúveis, pH, acidez titulável e razão SS AT-1). Os resultados demonstraram que os tratamentos foram efetivos na manutenção da aparência visual dos frutos e redução da perda de massa ao longo dos dez 10 de armazenamento. No que se refere à manutenção dos SS, todos os tratamentos foram eficientes durante o período de armazenamento, enquanto apenas os tratamentos com 2% e 3% de amido mantiveram o pH. Os revestimentos utilizados não foram efetivos na conservação da acidez dos frutos e a razão SS AT-1 aumentou a partir do 7º dia de conservação. O revestimento com 3% de amido apresentou os melhores resultados para todos os parâmetros avaliados.

Cell technologies in the regenerative medicine of the heart: main problems and ways of development
Authors: Agladze K. I.
Published: August 2019

The potential of heart tissues for self-regeneration is not high and supposedly limited to a small number of the niche stem cells. This makes it extremely important to develop regenerative technologies for the myocardium based on modern techniques, for instance, cell re-programming and 3D bioprinting. However, it is often difficult to differentiate the  sensational reports regularly appearing in mass media on “breakthrough” technologies from those that really have practical applications. The article sets out a point of view on the popular technologies for the regeneration of cardiac tissues and myocardium as a whole and reviews their drawbacks. The main problems of the bioprinting approach being actively developed include a low differentiation level with printing by stem cells that does not allow for a full-fledged cardiac tissue without foreign inclusions, as well as technological impossibility, when printing with stem cells, to set up their links with other cells during cell delivery in their corresponding matrix locations. Despite some optimistic reports on the good performance on stem or induced pluripotent cells injections into the myocardial injury zone that were first made public about 20  years ago, nowadays this idea seems rather doubtful, because in the recent years there has been virtually no positive effect of this procedure with a serious risk of complications. As far as growing of heart muscle elements is concerned, the main challenge is the development of the “proper” vascularization of the muscle being grown. At the same time, one has to emphasize practical feasibility of growing relatively small myocardial elements, such as sinus node.

Authors: HANAY Özge , TÜRK Hande
Published: August 2019

Pharmaceutically active compounds are gaining the recognition of emerging environmental contaminants classified as recalcitrant bio-accumulative compounds hence they are regarded as toxic and hazardous chemicals. In this context, efficient treatment processes are needed. Nanotechnology can adequately address many of the water quality issues by using different types nanomaterials. Nano zero valent iron (nZVI) has been applied to remove various organic compounds from aqueous solutions since the removal mechanism depends on adsorption and degradation. This article summarizes the recent knowledge of nZVI in pharmaceutical degradation considering the key factors such as initial contaminant concentration, dosage of bare and modified nZVI, pH of aqueous matrix and reaction time which are mainly examined in the experiments. Additionally, the degradation mechanism of studied pharmaceutical compounds monitored by observing intermediates and end-products is presented.
