Authors: Milhomen Eduarda do Carmo , Bomfim Maria Eduarda Domience , Andrade Daniela Maria de , Pina Neves Regina da Silva 
Published: March 2024

No segundo semestre de 2022, na disciplina de Geometria para o Ensino II, no Curso de Licenciatura em Matemática da Universidade de Brasília, cinco licenciandos colaboraram com o objetivo de desenvolver uma Tarefa Matemática (TM) relacionada à deformação de ângulos e áreas em projeções cartográficas. Após o estudo teórico sobre Tarefas Matemáticas, o grupo aprimorou a TM por meio de apresentações e debates coletivos na disciplina. Esse processo também envolveu análise conceitual, simulação do desenvolvimento da TM em sala de aula e planejamento para antecipar os possíveis desafios dos alunos. A TM foi desenvolvida em uma turma de 3º ano do Ensino Médio Técnico Integrado ao Meio Ambiente no Instituto Federal de Brasília, Campus Estrutural. Os resultados revelaram que os alunos do ensino médio enfrentaram dificuldades em associar as observações do experimento aos conceitos de distorção, tangência e projeção. Ao longo do processo de construção, validação, desenvolvimento e avaliação da TM, os licenciandos reconheceram a importância do cuidado no planejamento e preparação de ações de ensino de matemática, especialmente quando se busca uma maior interação dos alunos com os conceitos e sua aplicação na realidade.

Application of real-time water temperature prediction system in winter for long-distance water diversion projects
Authors: Xu Zepeng , Liu Mengkai , Huang Minghai , Wen Letian , Guo Xinlei 
Published: March 2024

ABSTRACT

Water diversion projects in high-latitude areas often reduce the risk of ice jams in winter by reducing the water transfer flow, which might cause the waste of water transfer benefits. This paper establishes a real-time prediction system of water temperature in winter, which can predict the change in water temperature by inputting the air temperature forecast data and the current hydraulic data. Taking the middle route of the south-to-north water diversion project as the background, the model parameters calibration and system application testing at different time periods are carried out. The results show that the prediction errors of water temperature for the 1 and 7 days are relatively small, and the prediction errors of water temperature at four observation stations can be controlled within ±0.3 and ±0.6 °C, with the root mean square error (RMSE) ranging from 0.07 to 0.25 and 0.12 to 0.36, respectively. The 15-day water temperature prediction results are greatly affected by air temperature input conditions. The prediction errors for the first 7 days are relatively small, ranging from −0.59 to 0.36 °C, and the errors for the last 8 days increase as the accuracy of the air temperature forecast decreases, ranging from −2.42 to 0.22 °C.

Published: March 2024

Abstract

In order to identify and effectively control the impact of NO3− pollution on human health, on the basis of investigation, sampling, analysis and testing, statistical analysis software (SPSS19), groundwater pollution analysis software, Nemera comprehensive index method, correlation analysis method and human health risk assessment model are applied for analysis and research. The results indicate that the groundwater in the study area is mainly Class II water, with overall good water quality. The main influencing factors for producing Class IV are NO3−, Fe, F− and SO42−. The use of agricultural fertilizers is the main source of NO3− exceeding standards in groundwater in this area. There are significant differences in the health hazards caused by NO3− pollution in groundwater among different populations, and infants and young children are more susceptible to nitrate pollution. The division of pollution areas and high-risk groups plays an important guiding role in preventing health risks. The new achievements will help people improve their awareness of risk prevention, caring for the environment, respecting nature and implementing precise policies, promoting society to step onto the track of scientific and healthy development.
Crossed Aphasia without Hemiparesis in a Dextral: A Case Report
Authors: Damodaran Anandi , Abdoqasem Rehab , Bandey Hamid Saima , Nayak kotekar Devdutt 
Published: March 2024

Introduction:
Aphasia, also known as language impairment, is a condition that affects the ability to express and understand language, as well as the ability to
communicate. Crossed Aphasia in Dextral (CAD) is defined as aphasia after a right hemispheric stroke. Usually, aphasia is caused by a left-sided
stroke in right-handed individuals. The prevalence of crossed aphasia in right-handed individuals is 0.38% to 3%. CAD is diagnosed when the
following factors are present: aphasia, right-handed patient, no family h/o left-handedness, the structural integrity of the left hemisphere, and
absence of brain damage in childhood. Another entity, Global Aphasia Without Hemiparesis (GAWH), is a rare stroke syndrome presenting with
global aphasia without any weakness and occurs in the lesion of the left-sided peri-sylvian region.

Case Report:
A 56-year-old female with a known case of severe mitral stenosis with chronic AF on warfarin and not on regular medications was brought to our
hospital as she had not communicated for the past day. On initial examination, the patient was conscious, globally aphasic, with left facial lag and
no weakness of limbs. Her initial Computed Tomography (CT) brain scan was normal. She was not thrombolysed as she was out of the window.
Brain Magnetic Resonance Imaging (MRI) showed right frontal, temporal, and parietal infarct in middle cerebral artery territory. She was treated
conservatively with full-dose anticoagulation and, upon discharge, was started on oral anticoagulants. At the time of discharge, the patient was able
to understand a few commands and was having echolalia with non-fluent speech. She was reviewed again at 3 months, and she had a full recovery
of her speech.

Discussion:
CAD is a rare stroke syndrome with low prevalence. Even though all subtypes of aphasic syndromes are seen in CAD, Broca's aphasia is the
common subtype, and men are affected commonly. Most patients also present with apraxia and visuospatial neglect. Our patient had all the criteria
for the diagnosis of CAD and also had GAWH and showed rapid recovery. The cause of the disease in this patient was considered to be two
different lesions involving language areas due to an embolism in her heart.

Conclusion:
This case has been presented for its rarity due to the occurrence of both CAD and GAWH in the same patient in a right-sided infarct.
The Right Ventricle in Pulmonary Arterial Hypertension: An Organ at
the “Heart of the Problem”
Authors: Singh Siddharth , Lewis Michael I. 
Published: March 2024

:
Pulmonary Arterial Hypertension (PAH) is a progressive disease with no cure. A major
determinant of outcome is the function of the right ventricle (RV). Unfortunately, progressive RV
dysfunction and failure can occur despite PAH-specific therapies. While initial adaptive hypertrophic
changes occur to maintain cardiac output and preserve contractile function and reserve,
maladaptive changes occur in the RV muscle that contribute to RV systolic and diastolic dysfunction
and failure. These include impaired angiogenesis / decreased capillary density with ischemia,
fibrosis, cardiomyocyte apoptosis and impaired autophagy, inflammation, enhanced oxidative
stress, altered metabolism, etc. Of note, there are no therapies currently approved that offset these
changes and treatment of RV dysfunction is largely supportive only. Further patients often do not
qualify for bilateral lung transplantation because of co-morbidities such as renal impairment.
Thus, a dire unmet need exists regarding the management of RV dysfunction and failure in patients
with PAH.
In this State-of-the-Art review, we comprehensively outline the unique features of the RV compared
to the left ventricle (LV) under normal circumstances and highlight the unique challenges
faced by the RV when confronted with increased afterload as occurs in PAH. We provide detailed
insights into the basis for the adaptive hypertrophic phase as well as detailed commentary into the
pathophysiology of the maladapted dysfunctional state as well as the pathobiological aberrations
occurring in the RV muscle that underlines the progressive dysfunction and failure that commonly
ensues. We also review comprehensively the evaluation of RV function using all currently employed
imaging, hemodynamic and other modalities and provide a balanced outline of strengths
and limitations of such approaches with the treating clinician in mind. We outline the current approaches,
albeit limited to chronic multi-modal management of RV dysfunction and failure. We
further outline new possible approaches to treatment that include novel pharmacologic approaches,
possible use of cellular/stem cell therapies and mechanical approaches. This review is directed
to the treating clinician to provide comprehensive insights regarding the RV in patients with PAH.
Impact of Caffeine Intake Strategies on Heart Rate Variability during
Post-Exercise Recovery: A Systematic Review and Meta-Analysis
Authors: Almeida Bianca Araujo , Morales Anderson Pontes , Ribeiro José Ricardo Claudino , Sampaio-Jorge Felipe , Ribeiro Yasmin Garcia , Barth Thiago , Ribeiro Beatriz Gonçalves 
Published: March 2024

Objectives:
The objective of this systematic review and meta-analysis is to evaluate
the influence of caffeine (CAF) intake strategies, taking into account their form, timing, and dosage,
on heart rate variability (HRV) indices in the post-exercise recovery period.

Methods::
The meta-analysis adhered to the Preferred Reporting Items for Systematic Review
and Meta-Analysis (PRISMA) guidelines and is registered in the PROSPERO database
(CRD42023425885). A comprehensive literature search was carried out across MEDLINE, Web
of Science, LILACS, and SCOPUS, concluding in May 2023. We concentrated on randomized
clinical trials comparing CAF supplementation effects to placebo on HRV indices post-exercise
in active adults aged 18 and above. The primary endpoint was the assessment of HRV indices,
measured both prior to and following exercise.

Results:
Of the 10 studies included, 7 were used for the meta-analysis, and all contributed to the
systematic review. The research explored a variety of CAF strategies, spanning different forms
(capsule, drink, gum), times (10, 45, 60 min) and doses (2.1 to 6.0 mg/kg). The outcomes revealed
no substantial variations between the placebo and CAF conditions in terms of both the
square root of the average of successive squared differences between adjacent RR intervals
(RMSSD) (standardized mean difference (SMD) -0.03, 95% CI -0.265 to 0.197, p=0.77) and
high frequency (HF) index (SMD -0.061, 95% CI -0.272 to 0.150, p=0.57). Furthermore, metaregression
analysis, employing a fixed-effects model and accounting for the administered CAF
doses, revealed no significant correlation between caffeine doses and HRV indices (p>0.05).

Conclusion:
In conclusion, there is moderate-certainty evidence suggesting that different CAF
intake strategies, encompassing aspects such as form, time, and dose, do not have a significant
impact on HRV indices recovery post-exercise (i.e., vagal modulation).
Which Laboratory and Clinical Feature are different in Pregnant and Non-pregnant Women with COVID-19? A Cross-sectional Study in the West of Iran
Authors: Talebi-Ghane Elaheh , Radnia Nahid , Daneshvar Fariba , Garousian Maryam , Bashirian Saeed , Khazaei Salman , Alimohammadi Neda 
Published: March 2024

Background:
This study aimed to determine the differences in laboratory and clinical
characteristics of pregnant and non-pregnant women with COVID-19 in Hamadan, the west of Iran.

Material & Methods:
This cross-sectional study compared 135 pregnant with 135 non-pregnant
women without underlying diseases and matched by age with COVID-19 from March 2020 to June
2021 in Hamadan, a western city in Iran. Their demographic characteristics, clinical symptoms, vital
signs, and laboratory findings were evaluated using a preset checklist and contrasted between the two
groups. The adjusted odds ratios (ORs) for the outcomes of illness were presented. A considerable
amount of analysis was performed on all data using the SPSS version 26 software.

Results:
In general, there was a significant association between most clinical symptoms and status of
pregnancy. Although the Peripheral oxygen saturation with a pulse oximeter (SPO2) mean was significantly
lower among non-pregnant compared to the pregnant women (89.19±4.52 versus
94.91±3.12; p < 0.001), the mean of heart rate was significantly lower among pregnant women compared
to non-pregnant women (90.59±11.80 versus 96.50±15.02; p = 0.001). The percentage of low
hemoglobin (Hb), abnormal Blood Urea Nitrogen, high Creatinine (CR), high Erythrocyte Sedimentation
Rate and high Lactate Dehydrogenase was significantly higher in non-pregnant women compared
to the pregnant women. Women with pregnancy compared to non-pregnant women and women
with low Hb compared to normal Hb had a considerably increased chance of intensive care unit
/death. Each unit increase in SPO2 and pulse rate resulted in a considerable reduction in this risk. In
addition, women with high CR, shortness of breath and per unit rise in temperature had a considerably
higher chance of staying in the hospital for a longer period of time.

Conclusion:
The clinical and para-clinical manifestations of pregnant women with COVID-19 are
different from non-pregnant women. Although there was a significant difference between the two
groups due to mortality, the percentage of admission to the intensive care unit in pregnant women
with COVID-19 is higher than in non-pregnant women. To avoid these adverse outcomes, pregnant
women should take precautions to avoid COVID-19 infection.
Physical, Chemical and Enzymatic Changes in Amla (Emblica officinalis) Fruit during Growth and Maturation
Authors: Sachan Neelam , Kumar Vivek 
Published: March 2024

Background:
Amla (Emblica officinalis) is one of the most prominent fruits in terms of nutritional and medicinal properties and is utilized for the preparation of many traditional pro-cessed foods and in Ayurvedic formulations.

Objective:
This study aims to investigate the enzyme activity and physical and chemical quality parameters during the growth and development stages of amla fruit for the determination of proper harvesting time to get optimum nutrient contents of fruit.

Methods:
The amla fruits of the chakaiya variety were harvested at 135 to 270 days after fruit set (DAFS) in 2021 and 2022 to study the various physical, chemical and enzymatic changes during growth and maturation.

Results:
The geometrical and gravimetric attributes of the fruit, viz. diameter, height, weight, volume, surface area, sphericity, aspect ratio, and radius of curvature increased. However, densi-ty decreased with the growth and maturation of the fruit. Furthermore, the rolling resistance, yel-lowness index and firmness of the fruit increased during the entire harvesting period of 135 to 270 DAFS. Total soluble solids and titratable acidity of the fruits increased only up to 195 DAFS and after that, continuously decreased. In contrast, ascorbic acid concentration grew in the entire growth and development period. Tannin, phenolic compounds and naringin content of the fruit steadily dropped until the final stage of harvest. Pectin Methyl Esterase (PME) activity was detected very low, 0.009 unit/ml at 135 DAFS, but as the fruit grew and matured, activity in-creased to 0.307 unit/ml at 270 DAFS. Polygalactouronase (PG) activity was not detected until 210 DAFS and, therefore significantly increased with maturity.

Conclusion:
Considering the optimal value of all studied physical, chemical and enzymatic at-tributes of the fruit during the entire harvesting period of 135 to 270 DAFS, the optimal harvesting time of the fruit was 210 DAFS.

A Digital Health Intervention Platform (Active and Independent Management System) to Enhance the Rehabilitation Experience for Orthopedic Joint Replacement Patients: Usability Evaluation Study
Authors: Papadopoulos Petros , Soflano Mario , Connolly Thomas 
Published: March 2024

Background
Optimal rehabilitation programs for orthopedic joint replacement patients ensure faster return to function, earlier discharge from hospital, and improved patient satisfaction. Digital health interventions show promise as a supporting tool for re-enablement.

Objective
The main goal of this mixed methods study was to examine the usability of the AIMS platform from the perspectives of both patients and clinicians. The aim of this study was to evaluate a re-enablement platform that we have developed that uses a holistic systems approach to address the de-enablement that occurs in hospitalized inpatients, with the older adult population most at risk. The Active and Independent Management System (AIMS) platform is anticipated to deliver improved patient participation in recovery and self-management through education and the ability to track rehabilitation progression in hospital and after patient discharge.

Methods
Two well-known instruments were used to measure usability: the System Usability Scale (SUS) with 10 items and, for finer granularity, the User Experience Questionnaire (UEQ) with 26 items. In all, 26 physiotherapists and health care professionals evaluated the AIMS clinical portal; and 44 patients in hospital for total knee replacement, total hip replacement, or dynamic hip screw implant evaluated the AIMS app.

Results
For the AIMS clinical portal, the mean SUS score obtained was 82.88 (SD 13.07, median 86.25), which would be considered good/excellent according to a validated adjective rating scale. For the UEQ, the means of the normalized scores (range −3 to +3) were as follows: attractiveness=2.683 (SD 0.100), perspicuity=2.775 (SD 0.150), efficiency=2.775 (SD 0.130), dependability=2.300 (SD 0.080), stimulation=1.950 (SD 0.120), and novelty=1.625 (SD 0.090). All dimensions were thus classed as excellent against the benchmarks, confirming the results from the SUS questionnaire. For the AIMS app, the mean SUS score obtained was 74.41 (SD 10.26), with a median of 77.50, which would be considered good according to the aforementioned adjective rating scale. For the UEQ, the means of the normalized scores were as follows: attractiveness=2.733 (SD 0.070), perspicuity=2.900 (SD 0.060), efficiency=2.800 (SD 0.090), dependability=2.425 (SD 0.060), stimulation=2.200 (SD 0.010), and novelty=1.450 (0.260). All dimensions were thus classed as excellent against the benchmarks (with the exception of novelty, which was classed as good), providing slightly better results than the SUS questionnaire.

Conclusions
The study has shown that both the AIMS clinical portal and the AIMS app have good to excellent usability scores, and the platform provides a solid foundation for the next phase of research, which will involve evaluating the effectiveness of the platform in improving patient outcomes after total knee replacement, total hip replacement, or dynamic hip screw.
