Published: May 2021

Objectives. The effect of COVID-19 infection in pregnant women and her neonate is not well-understood, with no clear evidence for vertical transmission. This study aims to determine the maternal and neonatal clinical characteristics and the dyad’s outcomes among those infected with COVID-19 infection.
Methods. An ambispective cross-sectional study involving pregnant women with confirmed COVID-19 infection was conducted at the Philippine General Hospital from April to August 2020. Two hundred nine obstetric patients were included, 14 of whom consented to specimen collection to determine vertical transmission.
Results. The majority of pregnant women with COVID-19 infection and their neonates had good outcomes. Labor, delivery, and the immediate postpartum course were generally uneventful. The all-cause maternal morbidity rate was high at 75.6 per 100 cases during the five-month study period. COVID-19 related morbidities included the development of Guillain-Barré Syndrome. The in-hospital all-cause maternal mortality rate was 1.91 per 100 cases. The causes of maternal death were acute respiratory failure, septic shock, and congenital heart disease (atrial septal defect with Eisenmengerization). The in-hospital, all-cause neonatal mortality rate was 1.04 per 100 neonates of cases. The lone mother and infant deaths were in a postmortem rt-PCR swab negative mother with an rt-PCR swab positive live neonate who eventually succumbed after nine days of life. All 14 dyads with collected specimens that included amniotic fluid, placental tissue, umbilical cord, and neonate nasopharyngeal swab tested negative for SARS-CoV-2 rt-PCR.
Conclusion. The prognosis for COVID-19 infected pregnant patients was generally good, with most of the patients discharged improved. Almost all of the neonates born to COVID-19-infected mothers were stable-term infants. There was no evidence for vertical transmission, as shown by negative rt-PCR results for all the additional specimens obtained.
In general, the prognosis for COVID-19 infected dyads was good. The majority of the mothers were discharged well with their term infants. All possible maternal sources of COVID-19 infection to the neonate tested negative. This study provided no evidence for vertical transmission.

Amplitude de Movimento de Dorsiflexão e a Força de Reação do Solo como fatores de risco de Lesões em Membros Inferiores em atletas da Ginástica Artística Feminina
Authors: Aguiar Gengnagel Gabriela , Aparecida Elias Dantas Renata 
Published: May 2021

A Ginástica Artística (GA) é um esporte admirado por inúmeros telespectadores, devido à suas diversas acrobacias e saltos que aparentam grande grau de dificuldade para a execução e permite que os praticantes estejam constantemente desafiando as leis da física. Embora seja um esporte precoce, iniciado ainda na infância, a GA possui (assim como todos os esportes) um índice lesivo, sendo este, maior entre as mulheres com ênfase nos membros inferiores.Dentre as regiões anatômicas mais acometidas, estão tornozelo e joelho. Fatores de risco como uso excessivo das articulações, força de reação do solo e baixa amplitude de movimento de dorsiflexão podem estar relacionados a lesões ainda em atletas jovens. Diante do exposto, o objetivo deste estudo foi analisar as variáveis de dorsiflexão de tornozelo e força de reação do solo e relacioná-los como fatores de risco de lesões em membros inferiores para atletasdas categorias pré-infantil, infantil e juvenil da Ginástica Artística Feminina (GAF). Foram realizadas coletas de dados antropométricos, de força de reação do solo e de amplitude de movimento de dorsiflexão com 23 ginastas, no Centro de Iniciação Desportiva - Setor Leste. Trata-se de um estudo transversal de análise descritiva. Os dados obtidos nesta pesquisa, indicaram uma possível propensão das atletas a desenvolverem lesões nas articulações do joelho e tornozelo, uma vez que, os resultados demonstraram que 25% sentem ou jásentiram dor no tornozelo e 54% relataram sentir ou já tiveram episódio de dor e/ou lesão no joelho. Além disso, estas articulações estão mais vulneráveis, pois as atletas que apresentaram menor grau de Amplitude de Movimento de Dorsiflexão (27%), apresentaram maior Força de Reação do Solo. Concluiu-se por meio deste, que a relação entre baixa amplitude de movimento de dorsiflexão e alta força de reação do solo podem ser consideradas fatores de risco de lesões em membros inferiores e / ou explicar possíveis traumas e lesões já sofridos no histórico das atletas, todavia ainda são poucos os estudos sobre o tema, sendo necessário pesquisas mais aprofundadas para uma melhor precisão dos resultados e conclusões.

Relationship between Teacher Educators’ Attitude towards Computers and their Level of ICT Integration in Instruction in Primary Teacher Training Colleges in Kenya
Authors: Bernard Chemwei  
Published: May 2021

This study examines the relationship between teacher educators’ attitudes towards computers and their level of ICT integration in instruction in public primary teacher training colleges in Kenya. Rogers’s Theory on the Diffusion of Innovations (2003) is used to understand the key factors affecting ICT integration as well as the teacher educators’ attitudes towards ICT integration in the classroom. In terms of methodology, the simple random sampling technique was used to select six teacher training colleges in Kenya and 169 respondents to participate in the study. Data was collected using a questionnaire, interview schedule and observation. Descriptive statistics were used to analyse the data collected for means, frequencies, means, percentages and standard deviation. The Pearson Moment Correlation was used to determine the relationship between teacher educators’ attitude and their level of ICT integration. The study results indicated a low level of ICT integration in teaching in all teacher-training colleges. It was also noted that teacher educators had positive attitudes towards ICT integration. However, they did not seem to integrate the available ICTs in their classroom instruction. It was further established that there was a positive relationship between their attitude and their level of ICT integration in instruction. The Ministry of Education should organise in-service training for teacher educators in teacher education institutions on ICT integration in instruction. At the same time, there is a need to applaud and encourage by means of incentives teacher educators who exhibit positive attitudes so as improve their ICT integration in their teaching. Consideration should be given to older teacher educators’ who may be holding poor attitudes towards computers.

Influence of physical exercise on cardiovascular parameters in students with different types of blood flow autoregulation
Authors: Melnik S. N. , Belaya L. A. 
Published: May 2021

Objective:to assess cardiovascular parameters in medical students depending on the type of blood flow autoregulation during physical exercise.Material and methods.We examined 58 students whose average age was 19 ± 1.13 years. During the examination, we recorded electrocardiograms (ECG), registered the parameters of central hemodynamics and determined systolic and diastolic blood pressure and heart rate. We performed the comparison of the parameters of the cardiovascular system (CVS) in students with different types of blood flow autoregulation (BFA) (cardiac, cardiovascular and vascular) during physical exercise.Results.The study has identified the dynamics of electrocardiographic and rheographic parameters during physical exercise expressed in excessive activation of energy resources and strain of the CVS functioning in young men with the cardiac type of BFA, which provides adaptation to short-term effects of disturbing environmental factors. On the contrary, the vascular type of BFA is the most economical, and this type of CVS has a wide range of the function mobilization to long-term physical activity.Conclusion.The study has found statistically significant differences in the cardiovascular parameters in the students with different types of blood flow autoregulation during physical activity.
The impact of volcanic eruptions of different magnitude on stratospheric water vapor in the tropics
Authors: Kroll Clarissa Alicia , Dacie Sally , Azoulay Alon , Schmidt Hauke , Timmreck Claudia 
Published: May 2021

Abstract. Increasing the temperature of the tropical cold-point region through heating by volcanic aerosols results in increases in the entry value of stratospheric water vapor (SWV) and subsequent changes in the atmospheric energy budget. We analyze tropical volcanic eruptions of different strengths with
sulfur (S) injections ranging from 2.5 Tg S up to 40 Tg S using EVAens, the 100-member ensemble of the Max Planck Institute – Earth System Model in its low-resolution configuration (MPI-ESM-LR) with artificial volcanic forcing generated by the Easy Volcanic Aerosol (EVA) tool. Significant increases in SWV are found for the mean over all ensemble members from 2.5 Tg S onward ranging between [5, 160] %. However, for single ensemble members, the standard deviation between the control run members (0 Tg S) is larger than SWV increase of single ensemble members for eruption strengths up to 20 Tg S.
A historical simulation using observation-based forcing files of the Mt. Pinatubo eruption, which was estimated to have emitted (7.5±2.5) Tg S, returns SWV increases slightly higher than the 10 Tg S EVAens simulations due to differences in the aerosol profile shape. An additional amplification of the tape recorder signal is also apparent, which is not present in the 10 Tg S run. These differences underline that it is not only the eruption volume but also the aerosol layer shape and location with respect to the cold point that have to be considered for post-eruption SWV increases.
The additional tropical clear-sky SWV forcing for the different eruption strengths amounts to [0.02, 0.65] W m−2, ranging between [2.5, 4] % of the aerosol radiative forcing in the 10 Tg S scenario. The monthly cold-point temperature increases leading to the SWV increase are not linear with respect to aerosol optical depth (AOD) nor is the corresponding SWV forcing, among others, due to hysteresis effects, seasonal dependencies, aerosol profile heights and feedbacks. However, knowledge of the cold-point temperature increase allows for an estimation of SWV increases of 12 % per Kelvin increase in mean cold-point temperature. For yearly averages, power functions are fitted to the cold-point warming and SWV forcing with increasing AOD.
Fifty-six years of surface solar radiation and sunshine duration over São Paulo, Brazil: 1961–2016

Published: May 2021

Abstract. A total of 56 years (1961–2016) of daily surface downward solar
irradiation, sunshine duration, diurnal temperature range and the fraction
of the sky covered by clouds in the city of São Paulo, Brazil, were
analysed. The main purpose was to contribute to the characterization and
understanding of the dimming and brightening effects on solar global
radiation in this part of South America. As observed in most of the previous
studies worldwide, in this study, during the period between 1961 and the early
1980s, a negative trend in surface solar irradiation was detected in
São Paulo, characterizing the occurrence of a dimming effect. Sunshine
duration and the diurnal temperature range also presented negative trends,
in opposition to the positive trend observed in the cloud cover fraction.
However, a brightening effect, as observed in western industrialized
countries in more recent years, was not observed. Instead, for surface
downward irradiation, the negative trend persisted, with a trend of −0.13 MJ m−2 per decade, with a p value of 0.006, for the 56 years of data and
in consonance with the cloud cover fraction increasing trend, but not
statistically significant, of 0.3 % per decade (p value = 0.198). The
trends for sunshine duration and the diurnal temperature range, by contrast,
changed signal, as confirmed by a piecewise linear regression model. Some
possible causes for the discrepancy are discussed, such as the frequency of
fog occurrence, urban heat island effects, horizontal visibility (as a proxy
for aerosol loading variability) and greenhouse gas concentration increase.
Future studies on the aerosol effect are planned, particularly with higher
temporal resolution, as well as modelling studies, to better analyse the
contribution of each possible cause.
