Published: May 2021

La contaminación que existe en la Playita del Guasmo ubicada en el estero Cobina de Guayaquil, Ecuador, se debe a varias fuentes de contaminación que lo rodean (fábricas, comercio, turismo y aguas residuales). Siendo este un lugar turístico bastante concurrido, se planteó como objetivo evaluar la calidad del agua del sector la Playita del Guasmo. Se tomaron muestras de agua en 9 estaciones en la playita del Guasmo que cuenta con una distancia de 270 m, durante los meses febrero - abril de 2015. Cada estación fue identificada con un código y con coordenadas geográficas mediante Sistema de Posición Global, el estudio realizó 4 monitoreos cada 15 días. Para la toma y numeración de las muestras se siguieron los protocolos estandarizados por el INOCAR (Instituto Oceanográfico de la Armada). Con respecto a los resultados obtenidos, los valores de turbidez y sólidos suspendidos totales concuerdan con las altas temperaturas encontradas, debido a que las partículas en suspensión absorben calor. Los valores más altos se encontraron en las estaciones E1, E2 y E3, cercanas a la población, así como en la estación E7 por la presencia del sector camaronero. De acuerdo con los resultados obtenidos las condiciones fisicoquímicas y microbiológicas del área de estudio según el Índice de Calidad Ambiental del Agua “WQI 2015” presenta un nivel regular con un valor de 57,07 según los rangos establecidos por el ICA-NFS.

Published: May 2021

Se realizó el análisis de la relación existente entre los procesos cognitivos y afectivos como determinante de la conducta del consumidor en 255 estudiantes universitarios, en edades entre 20 a 35 años, 36 % fueron hombres y 64 % mujeres. El objetivo fue describir la conducta del consumidor desde los parámetros cognitivos y afectivos explicados desde la neuropsicología. Para la recopilación de información se utilizó el cuestionario de atributos múltiples de Fishbein y el Inventario de personalidad, versión IPIP (16PF-IPIP), de Goldberg. Entre las conclusiones más relevantes, se estableció que las personas que seleccionan objetos de consumo tuvieron una actitud extrovertida, con busca de estabilidad emocional, gregarismo e imaginación a la hora de elegir un producto, por otro lado, en los procesos cognitivos, afectivos y conativos, se obtuvo que el sabor o sazón es determinante a la hora de elegir un producto en 91 %. La variedad de productos satisface el gusto y preferencias a la hora de elegir un producto con el 88,6 % y el buen servicio que recibe es determinante a la hora de volver a comprar un producto en 86,7 %. Se pudo observar en la descripción de la intencionalidad de la conducta, las creencias, convicciones, presión social, que permiten realizar la evaluación de la conducta en la elección del objeto de consumo.
ABSTRACT
An analysis was made of the relationship between cognitive and affective processes as a determinant of consumer behavior in 255 university students, between 20 and 35 years old, 36% were men and 64% were women. The objective was to describe the behavior of the consumer from the cognitive and affective parameters explained from neuropsychology. For the collection of information, the multi-attribute questionnaire of Fishbein, and the Personality Inventory, IPIP version (16PF-IPIP), was used Goldberg. Among the most relevant conclusions, it was established that people who select consumer objects had an extroverted attitude, looking for emotional stability, gregariousness and imagination when choosing a product, on the other hand, in cognitive, affective and conative processes, it was obtained that the flavor or seasoning is decisive when choosing a product in 91%. The variety of products satisfies the taste and preferences when choosing a product with 88.6% and the good service it receives is decisive when it comes to buying a product again at 86.7%. It could be observed in the description of the intentionality of the behavior, the beliefs, convictions, social pressure, that allow to conduct the evaluation of the behavior in the choice of the object of consumption.

Mortality Projection on Indonesia's Abridged Life Table to Determine the EPV of Term Annuity
Authors: Siswono Galuh Oktavia , Azmi Ulil , Syaifudin Wawan Hafid 
Published: May 2021

The life insurance industries usually use the Life Table for the valuation process, especially in calculating premiums and policy values of a policy. However, the Life Table is rarely updated; and it may even take years before they are updated. This happens because the insurers believe that the information in the Life Table is still related to the current state of a country and for the next several years. In fact, data and information related to mortality rates in a country are constantly changing and always being updated annually. Therefore, as an approach, researchers use the projection of mortality to approach the mortality rate in the future. Thus, future mortality data can be predicted so that better policies can be made by the governments or insurance industries. In this study, the Abridged Life Table of Indonesia is used in the projection of mortality for both sexes (male and female) of the population in Indonesia. The results of mortality projection are then used to calculate the Expected Present Value (EPV) of a term annuity-due under uniform distribution of deaths (UDD) for several values of and ages. The results obtained show that there is a decrease in the value of the mortality rate in the next few years. Therefore, it can be assumed that there is a possibility for longevity risk to occur in the future.

Authors: Kumar K Jagadish , Bhagiratha Smriti , Vishwanath Prashanth 
Published: May 2021

Introduction: Iron overload in thalassemia catalyses the production of a variety of reactive oxygen species leading to cumulative cell damage. Ischemia modified albumin (IMA) is an end product of oxidative stress. It is imperative to pick up oxidative stress early in order to prevent the organ damage in thalassemia. Therefore this study was undertaken to estimate IMA levels and to see the correlation between ferritin and IMA to establish whether ferritin can be a proxy marker for oxidative stress.
Methods: A total of 76 children were included in the study out of which 46 were diagnosed cases of β- Thalassemia major and 30 formed the healthy controls. Pre transfusion haemoglobin, AST, ALT, ferritin and IMA levels were estimated and compared with healthy control children. Correlation was drawn between haemoglobin, AST, ALT, ferritin with IMA.
Results: There is significant elevation in the level of IMA and ferritin in children with Thalassemia major as compared to the healthy controls (p = < 0.001). There was a significant positive correlation between ferritin and IMA and a significant negative correlation between haemoglobin % and IMA. Regression relationship between ferritin and IMA established that IMA (ng/ mL) = 246.118 + 0.829 (Ferritin ng/dL).
Conclusions: IMA levels were significantly elevated in β- thalassemia major children and correlated positively with ferritin levels. By establishing a regression relationship between ferritin and IMA levels, we can fairly estimate the levels of IMA. Hence, we can utilise ferritin as a proxy marker of oxidative stress instead of IMA.
Better Prediction of Neuro - Developmental Outcome in Babies Using Combined Vojta’s Neurokinesiological Examination, Amiel Tison Angles and Head Holding Grades
Authors: Jain Ashish , Veerabhadrappa H , Shrikant SW , Kumari Nisha 
Published: May 2021

Introduction: With the advances in medical technology, the survival rate has increased amongst the high-risk neonates. Changes occurring in the neuro-motor function during the first year of life are closely related to the maturation of the central nervous system of babies and the presence or absence of injury to brain. These should be detected as early as possible, so that intervention programmes can be started.
Methods: A prospective study was done in NICU of a teaching hospital, to find the predictive value of combined assessment by three neuro-developmental examinations Viz. Vojta’s Neurokinesiological examination, Amiel-Tison angles and head holding grades. Total 375 babies with various high risk category were included, out of which only 114 infants completed one-year follow-up. On the first visit a detailed neurological examination was performed using Vojtas Neurokinesological postures, Amiel- Tison angles and head holding grades based on Trivandrum Developmental Screening Chart (TDSC). At one year, the milestones attained were plotted against the BSID percentiles and babies assigned as developmentally delayed, if it was below 97% pass level. Sensitivity and specificity were calculated and propositions evaluated by chi-square test.
Results: 23% babies had developmental delay at one year. The important high risk factors were maternal risk factors 39%, HIE with MAS, HIE stage-III, complications during NICU stay.
Conclusions: Vojta’s Neurokinesiological examination is an effective screening test that can be applied to all high-risk neonates. The predictive value could be enhanced to 100%, by using other simple tests, like Amiel-Tison Angles and Head holding grades by TDSC.

Published: May 2021

Introduction: Preterm infants’ brain is vulnerable to ischemic and hemorrhagic injuries due to structural and molecular immaturities as well as associated co-morbidities, which is usually detected by bedside cranial ultrasound. Cranial ultrasound findings are common in preterm infants’ of < 32 weeks, so cranial ultrasound is routinely recommended in them but there is no such recommendation regarding moderate and late preterm infants. The objective of this study is to find the cranial ultrasound abnormalities in moderate and late preterm infants.
Methods: This prospective observational study was conducted in a tertiary level neonatal care unit. Hundred moderate and late preterm neonates delivered or admitted within seventh day of life were included in the study. Cranial ultrasound scan was performed between third and seventh day of life and before discharge and ultrasound findings were noted. Data were collected in predesigned case record form and analysed using Fischer Exact test.
Results: Out of 100 neonates, 47 (47%) were males and 53 (53%) females. There were 43 (43%) moderately preterm and 57 (57%) late preterm infants. Mean day of life for performing first and second cranial ultrasound was 4.17 (3 - 7) days and 13.24 (3 - 40) days respectively. Cranial abnormalities were noted in 26% neonates. Intra-ventricular haemorrhage grade 1 or 2 was the commonest abnormality noted. Choroid plexus cyst (4%), cerebral edema (3%), periventricular hyperechogenicity (3%) and hydrocephalus (1%) were the other abnormalities noted. Neonates having APGAR < 6 at one minute, mechanically ventilated and having co-morbidities had significantly higher incidence of abnormal findings.
Conclusions: It is reasonable to perform screening cranial ultrasound in high risk moderate and late preterm infants having low APGAR score, mechanically ventilated and having co-morbidities.

Authors: Yadav Sunil Kumar , Giri Arun , Khanal Bbita 
Published: May 2021

Introduction: Neonatal hyperbilirubinemia continues to be the commonest cause of nursery and NICU admissions and readmissions in the neonatal period worldwide. Although most cases are physiological, toxic levels of un-conjugated bilirubin can lead to acute and chronic bilirubin encephalopathy. Hence, this study aimed to study the risk factors for exchange range hyperbilirubinemia in neonates.
Methods: This was a hospital-based prospective observational study conducted in a teaching and referral NICU over a period of one year from July 2019 to August 2020. All neonates with diagnosis of hyperbilirubinemia requiring double volume exchange transfusion were included in the study. Risk factors for significant hyperbilirubinemia were analysed with descriptive statistics. P-value of < 0.05 was considered significant wherever applicable.
Results: The mean gestational age and birth weight were 38.06 ± 2.13wks and 2611.72 ± 389.39 gm respectively. Fifteen percent of the babies (162) developed hyperbilirubinemia and 28 (17.3%) required double volume exchange transfusion. Among neonates requiring exchange transfusion, 17 were females and 11 were males. Among 28 babies who required DVET, 20 (71.4%) were SGA. ABO incompatibility was present in 14 (50.0%) neonates and Rh incompatibility in 13 (46.4%) neonates. ABO along with Rh incompatibility was present in eight (28.6%) neonates. DCT was positive in six neonates with ABO incompatibility and nine neonates in Rh incompatibility. G6PD deficiency was present in four (14.3%) neonates.
Conclusions: The most important risk factors identified were small for gestational age, ABO and Rh incompatibility followed by oxytocin use and sibling treated for jaundice.

Published: May 2021

Justification: Sepsis is a major cause of morbidity and mortality in Nepal. There is a lack of standardisation in the management of severe sepsis and septic shock. Additionally, international guidelines may not be completely applicable to resource limited countries like Nepal.
Objective: Create a collaborative standardised protocol for management of severe sepsis and septic shock for Nepal based on evidence and local resources.
Process / Methods: Paediatricians representing various paediatric intensive care units all over Nepal gathered to discuss clinical practice and delivery of care of sepsis and septic shock under the aegis of Nepal Paediatric Society. After three meetings and several iterations a standardised protocol and algorithm was developed by modifying the existing Surviving Sepsis Guidelines to suit local experience and resources.
Recommendations: Paediatric sepsis and septic shock definitions and management in the early hours of presentation are outlined in text and flow diagram format to simplify and standardise delivery of care to children in the paediatric intensive care setting. These are guidelines and may need to be modified as necessary depending on the resources availability and lack thereof. It is recommended to analyse data moving forward and revise every few years in the advent of additional data.

BACKGROUND: Green synthesized nanoparticles have been earmarked for use in nanomedicine including for the development of better anticancer drugs. OBJECTIVE: The aim of this study was to undertake biochemical evaluation of anticancer activities of green synthesized silver nanoparticles (AgNPs) from ethanolic extracts of fruits (AgNPs-F) and leaves (AgNPs-L) of Annona muricata. METHODS: Previously synthesized silver nanoparticles were used for the study. The effects of the AgNPs and 5-Fluorouracil were studied on PC3, HeLa and PNT1A cells. The resazurin, migration and colonogenic assays as well as qRT-PCR were employed. RESULTS: The AgNPs-F displayed significant antiproliferative effects against HeLa cells with an IC50 of 38.58 μg/ml and PC3 cells with an IC50 of 48.17 μg/ml but selectively spared normal PNT1A cells (selectivity index of 7.8), in comparison with first line drug 5FU and AgNPs-L whose selectivity index were 3.56 and 2.26 respectively. The migration assay revealed potential inhibition of the metastatic activity of the cells by the AgNPs-F while the colonogenic assay indicated the permanent effect of the AgNPs-F on the cancer cells yet being reversible on the normal cells in contrast with 5FU and AgNPs-L. CASP9 was significantly over expressed in all HeLa cells treated with the AgNPs-F (1.53-fold), AgNPs-L (1.52-fold) and 5FU (4.30-fold). CXCL1 was under expressed in HeLa cells treated with AgNPs-F (0.69-fold) and AgNPs-L (0.58-fold) and over expressed in cells treated with 5FU (4.95-fold), but the difference was not statistically significant. CXCR2 was significantly over expressed in HeLa cells treated with 5FU (8.66-fold) and AgNPs-F (1.12-fold) but under expressed in cells treated with AgNPs-L (0.76-fold). CONCLUSIONS: Here we show that biosynthesized AgNPs especially AgNPs-F can be used in the development of novel and better anticancer drugs. The mechanism of action of the AgNPs involves activation of the intrinsic apoptosis pathway through upregulation of CASP9 and concerted down regulation of the CXCL1/ CXCR2 gene axis.
Outrunning COVID-19 II: My Trip to Aeæa

I live close to my university and I have been taking my meals at the school canteen but it has been shuttered because of COVID-19. Tonight I will make pasta in a double boiler: pasta cooks in the bottom and cherry tomatoes steam on top, served with olive oil. Not too shabby! The students are still in lockdown in the dormitory, going on four months now. I miss Rolande, a young woman from the DRC. “Roland" is a boy’s name, but my young woman friend Rolande, spelt with an “e”, was named after the famous hero of Roncesvalles even so, she tells me. I wish she could come for dinner again, and if only I had some Asiago cheese like I saw at Lille this summer to go with my pasta. I’ve been thinking like this a lot these days.
