Pediatric Lung Ultrasound (PLUS) in the diagnosis of Community-Acquired Pneumonia (CAP) requiring hospitalization
Authors: Talwar Neetu , Manik Lucky , Chugh Krishan
Published: May 2022

Background:

In childhood pneumonia, pediatric lung ultrasound (PLUS) is a very sensitive and specific diagnostic alternative to chest X-ray (CXR). However, there is a paucity of literature on this in India. We set out to compare the diagnostic accuracy of PLUS and CXR in hospitalized children with community-acquired pneumonia (CAP).

Setting and Design:

Prospective, observational study (June 2017–September 2019) at a tertiary care hospital.

Methods:

Hospitalized children of CAP (3 months–18 years) were included after taking informed, written consent. Hemodynamic instability, asthma, cystic fibrosis, congenital heart disease, immunodeficiency, and malignancy cases were excluded. CXR (frontal view) and PLUS were done within 6 h of each other and within 24 h of hospitalization. Statistical analysis was performed using SPSS software version 25.

Results:

Out of 612 consecutive, hospitalized respiratory cases, 261 were recruited. CAP was diagnosed clinically in 148 (56.7%) patients [95 boys (64.19%), mean age in years ± SDL: 4.31 ± 4.41]. Abnormal PLUS was present in 141 (95.27%) and abnormal CXR in 128 (86.48%) patients. In radiologically diagnosed pneumonia, PLUS was detected in 123 [123/128 (96.09%)] children, and when CXR was normal, PLUS was abnormal in 18 [18/20 (90%)]. PLUS showed a sensitivity of 95.27% (95% CI: 90.50–98.08) and a specificity of 92.90% (95% CI: 86.53–96.89). CXR showed a sensitivity of 86.49% (95% CI: 79.9–91.55) and a specificity of 90.27% (95% CI: 83.25–95.04).

Conclusions:

PLUS is a sensitive, specific test and can be considered as the preferred investigation before CXR in children hospitalized with CAP.

Authors: Aziz Danish Abdul , Abbas Aiza , Alam Anusha , Aziz Namrah
Published: May 2022

Introduction:

Cystic fibrosis (CF) remains under-diagnosed in Pakistan. CF population has increased tendency for Pseudomonas aeruginosa (Pa) infection and it is one of the leading causes of mortality. Utilizing inhaled antibiotics (IAs) for the treatment of Pa infection has been well established in the literature. There is limited data available on CF in Pakistan, especially regarding the efficacy of IAs. The aim of this study is to investigate the role of IAs on Pa infection in children and adolescents with CF.

Methodology:

CF patients enrolled between January 2012 and December 2019 were selected as part of this retrospective cohort study. CF patients from 2 to 18 years of age who cultured Pa on any respiratory sample and who had never been Pa-free in at least two sputum cultures in the previous 12 months were included. Patients were divided into an IA group and a noninhaled antibiotic (NIA) group based on the treatment they received. Follow-up was done between 3 and 6 months posttherapy on Pseudomonas growth in the sputum. The number of pulmonary exacerbations were documented for 6 months follow-up.

Results:

Eighty-one children with CF were enrolled during the study period, of which 39 were in the IA group and 42 were in the NIA group. There was no significant difference in their demographics and initial clinical characteristics. The mean pulmonary exacerbations after 6 months were lower in the IA group as compared to the NIA group (1.102 ± 0.50 vs. 2.45 ± 0.89: P = 0.001). Follow-up between 3 and 6 months showed greater Pseudomonas colonization in the IA group versus the NIA group (53.84% vs. 92.85%: P = 0.001).

Conclusion:

IAs in combination with airway clearance therapy and oral or IV antibiotics are an effective regimen for children with CF.

Published: May 2022

Background:

Understanding the spirometry-based prevalence with concomitant assessment of the health status is important to appreciate the chronic obstructive pulmonary disease (COPD)-scenario in a geographic area. There is hardly any such rural data available from the developing world.

Methods:

We screened the adult population (>40 but <75 years) of seven villages in two different blocks of Birbhum district, West Bengal, for the presence respiratory symptoms (active or historical within 1 year). Those screened positive were tested with spirometry to diagnose COPD on having post bronchodilator FEV1/FVC <0.7. The COPD subjects were then applied with COPD assessment test (CAT).

Results:

Out of 6255 subjects residing in the villages, 1984 subjects belonged to the target age group and 51.56% (1013 of 1984) of them qualified for spirometry which was possible in 953 (88.81%) of them. COPD was identified in 166 (16.36%) of symptomatic individuals. The calculated prevalence of COPD was 2.65% in overall population and 8.367% in population above 40 years. The COPD patients (mean age 59.77 ± 9.47 years) had a male preponderance (120 [72.29%] of 166). They were mostly malnourished (body mass index = 17.15 ± 2.97), with poorhealth status (CAT = 15) and moderate degree (GOLD category-II) of airflow limitation showing FEV1/FVC as 0.60 ± 0.07 and the mean post bronchodilator FEV1 as 52% of predicted (1.26 ± 0.42 L). Most of the sufferers (74.09%) were either active (n = 88) or ex-smokers (n = 35) (>10 pack-years). The nonsmokers constituted 25, 90% (n = 43).

Conclusion:

The rural COPD prevalence in Bengal is far higher than the estimated national average with the health status of the sufferers been poor.

Authors: Ghosh Tamoghna , Dwivedi Tanima , Agarwal Harsh , Iyer Hariharan , Tiwari Pawan , Mittal Saurabh , Gupta Ritu , Bhatnagar Sushma , Vig Saurabh , Mohan Anant
Published: May 2022

Background:

Severe acute respiratory syndrome coronavirus 2 (SARS CoV-2), which causes coronavirus disease 2019 (COVID-19), has rapidly evolved into a pandemic, affecting more than 90 million people and more than 1.9 million deaths worldwide. Despite extensive study, the prognostic role of various hematological and biochemical parameters remains unclear.

Methods:

This study was carried out at a COVID care facility in Delhi. The demographic and clinical information, laboratory parameters (hematological, biochemical, and inflammatory), and the treatment of admitted COVID-19 patients during first wave were collected from electronic medical records and were subsequently analyzed.

Results:

Between March 2020 and November 2020, a total of 5574 patients were admitted to hospital due to COVID-19. Majority (77.2%) were male and had a mean (standard deviation [SD]) age of 38.9 (14.9) years. The mean (SD) duration of hospital stay was significantly higher in nonsurvivors. Out of the entire cohort, 8.7% of the patients had comorbidities, whereas 47.1% of the patients were asymptomatic at presentation. Compared to the survivors, the nonsurvivors had a significantly higher proportion of comorbidities and were more likely to be symptomatic. Patients who died during hospital stay had significantly higher relative neutrophil percent and neutrophil–lymphocyte ratio and lower lymphocyte percent. The patients who died had significantly higher levels of ferritin, D-dimer, and fibrinogen.

Conclusions:

Analysis of various hematological and inflammatory parameters can provide useful prognostic information among COVID-19-affected patients. It can also help in identifying patients who merit aggressive institutional care and thereby potentially mitigate the mortality.

Published: May 2022

Introduction:

Acute kidney injury (AKI) in coronavirus disease (COVID-19) is understudied, especially after the initial pandemic wave and in South East Asian Region.

Materials and Methods:

This was a single-center retrospective cohort of 856 hospitalized COVID-19 cases between March 26, 2021, and June 7, 2021 in India to study the spectrum of AKI in COVID-19. The primary outcome was to analyze predictors of AKI. Other secondary outcome measured was mortality in AKI.

Results:

The incidence of AKI was 38.1%. The incidence of hemodialysis requirement was 3.5%. The proportion of AKI I, II, and III was 80.2%, 8.2%, and 11.6%, respectively. The mortality in AKI was statistically significantly higher than in non-AKI compared to AKI. Among the laboratory markers, the highest area under the curve (AUC) in the receiver operator curve was reached for red cell distribution width [AUC = 0.77 (0.73–0.81); P < 0.01]. The predictors for AKI calculated by multivariable logistic regression model in the cohort were obesity (hazard ratio (HR) = 3.2 (1.08–9.73); P = 0.04) and baseline European Cooperative Oncology Group (ECOG ≥ 3) (HR = 3.4 (1.77–6.69); P < 0.01). Similarly, the risk factors for developing AKI III included male sex (HR = 1.33 (1.05–1.68); P = 0.02) and ECOG ≥ 3 (HR = 1.5 [1.18–1.9]; P < 0.01).

Conclusion:

The incidence of AKI is high in hospitalized patients in the COVID-19 second wave. The mortality associated with AKI remains high. The comorbidity burden was not linked with AKI.

Published: May 2022

Background

Strabismus is a frequent ocular condition seen in optometry and ophthalmology clinics. In the United States, 3–5% of children are affected, with 126 400 new instances being reported each year.

Aim

The purpose of the study was to evaluate the effect of Z-tenotomy of lateral rectus when combined with conventional recession for correction of exotropia.

Patients and methods

This is a prospective, institutional clinical trial study that included 40 patients and took place at the Ophthalmology Department of Tanta University Hospital.

Results

The research was completed on 40 patients at any age and moderate-angle to large-angle comitant exotropia without any vertical deviations and who met the inclusion criteria. They were divided into four groups: group A patients had exotropia of angle of 20–30 prism diopters (PD), where one lateral rectus muscle was recessed 7–8 mm; group B patients had exotropia of angle of above 30–40 PD+where one lateral rectus was recessed 7–8 mm combined with Z-tenotomy; group C patients had exotropia of angle of above 40–50 PD, where both lateral rectus were recessed 7–8 mm, and group D patients had exotropia of angle of above 50–70 PD where both lateral rectus were recessed 7–8 mm combined with Z-tenotomy.

Conclusion

Z-tenotomy of lateral rectus combined with conventional recession 7–8 mm procedure appears to have augmented the effect of recession procedure while avoiding the risk of limiting ductions in the field of recessed muscle.

Published: May 2022

Senile purpura, a hemorrhagic disorder, may be caused either by functional impairment of platelets/blood vessel walls, by thrombocytopenia, or by blood clotting mechanism defects. Chronic kidney disease is a condition with decreased glomerular filtration rate. Chronic renal failure is one such disease that presents with a spectrum of oral manifestations such as uremic stomatitis, xerostomia, metallic taste, mucosal petechiae, ecchymosis, renal osteodystrophy, oral candidiasis, periodontal disease, mucosal lesions, and oral malignancies. Here, we report a case of senile purpura (ecchymosis) in an end-stage chronic kidney disease patient.

Authors: El Shazly Hagar N. , Shalaby Khaled H. , Mohammed Wesam S. , Ebrahim Ingy Abd El Wahab
Published: May 2022

Background

There are many reports about the association between low vitamin D (vit D) level and autoimmune thyroid diseases. Several researches have shown that supplementing vit D suppresses the autoimmune reaction reducing the level of thyroid autoantibodies.

Aim

The purpose of the study is to assess the relationship between vitamin D deficiency and autoimmune Hashimoto's thyroiditis (HT).

Patients and methods

This case–control study was conducted on 60 cases that were divided into two groups. Group A included 30 healthy cases serving as the control group and group B included 30 patients with known HT. Laboratory investigations including serum concentration of 25(OH)D3, serum calcium (Ca) and phosphorus (Ph), total and free T3, free T4, thyroid-stimulating hormone (TSH), antithyroid peroxidase, and anti-thyroglobulin antibodies, C-reactive protein, and erythrocyte sedimentation rate were done.

Results

Serum 25 (OH)D3 was significantly lower in HT patients compared with healthy controls. The incidence of 25(OH)D3 deficiency was increased in those patients. Comparison between the patient and control groups regarding serum Ca and serum Ph levels were statistically nonsignificant. Higher TSH, erythrocyte sedimentation rate, and C-reactive protein with lower serum T3, free T3, and free T4 levels were significantly higher with HT. Antithyroid peroxidase was elevated in all HT patients. Anti-thyroglobulin was elevated in all HT cases. There was a significant negative correlation between vit D level and the TSH and a significant positive correlation between vit D level and the Ca.

Conclusion

In HT patients, vitamin D deficiency is common, suggesting its role in developing the disease.

Authors: Alshahat Eman A. , Alnaghy Wageh S. , Taha Atef M. , Okda Hanaa I.
Published: May 2022

Background

Chronic hemodialysis patients are at considerably high risk for vascular access-related blood stream infections that may be associated with serious complications. Infections are more frequent with central venous catheters and polytetrafluoroethylene grafts than with arteriovenous fistula.

Aim

We aim to evaluate the prevalence of vascular access infection among hemodialysis patients, risk factors, common causative microorganisms and their antibiotics sensitivity.

Patients and method

This cross-sectional study included 720 end-stage renal disease patients on hemodialysis recruited from six hemodialysis centers in Al-Gharbia Governorate from June 2019 to June 2020.

Results

The prevalence of vascular access infection was 27.77%. Sex, old age, and diabetes mellitus had a significant statistical association. Temporary catheters recorded the highest infection rate. Gram-positive bacteria were the most common organisms in 57.5% of cases, Gram negative in 39.5% while candida albicans in only 3% of the cases. The antibiotic sensitivity was higher to amikacin and imipenem.

Conclusion

Creation of native arteriovenous fistula is highly recommended to avoid catheter-related blood stream infections and their complications. Strict adherence to antiseptic measures and use of a rational antibiotic policy for the early diagnosis and better management of hemodialysis vascular access site infection is important.

BACKGROUND: With the invasion of Ukraine by the Russian Army in February 2022, refugees, the majority of whom are women and children, started fleeing the war to neighbouring countries. Even before the current escalation, the conflict in the eastern part of Ukraine has led to the internal displacement of more than 200,000 children, and many others have experienced attacks, e.g. on schools. This inevitably leads to limitations in health care delivery. During transit, overcrowding, poor shelter and vulnerability may further put refugees at increased risk for infectious diseases. This consensus document aims to provide information and guidance regarding health issues that paediatricians and general practitioners may face when caring for Ukrainian children.
METHODS: Members of the Migrant Health Reference Group of Paediatrics Switzerland and the Paediatric Infectious Disease Group in Switzerland developed this recommendation between March and April 2022 in a modified Delphi process.
RESULTS: A total of 50 recommendations were agreed on with a ≥80% consensus. These include the following topics: i) general aspects, including interpreter services, urgent health needs, personal history and general check-ups; ii) mental health, including how to search for signs of psychological distress without going into traumatic details; iii) vaccinations, including recommendations for evaluation and catch-up; iv) screening for tuberculosis, human immunodeficiency virus, and hepatitis B and C; and v) providing age-appropriate preventive and health service information.
CONCLUSION: This document provides current evidence and guidance when caring for paediatric refugees from Ukraine. The recommendations focus on Switzerland but may well be used in other countries. These are based on current evidence and may need to be adapted to individual situations and once further evidence becomes available.

The causative agent of Chagas disease (Trypanosoma cruzi) is transmitted to mammals, including humans, mainly by insect vectors of the subfamily Triatominae (Hemiptera: Reduviidae). Also known as “kissing bugs”, the subfamily currently includes 157 validated species (154 extant and three extinct), in 18 genera and five tribes. Here, we present a subdataset (7852 records) of American triatomine occurrences; an update to the most complete and integrated database available to date at a continental scale. New georeferenced records were obtained from a systematic review of published literature and colleague-provided data. New data correspond to 101 species and 14 genera from 22 American countries between 1935 and 2022. The most important novelties refer to (i) the inclusion of new species, (ii) synonymies and formal transferals of species, and (iii) temporal and geographical species records updates. These data will be a useful contribution to entomological surveillance implicated in Chagas disease.

STUDY OF PHENOTYPIC VARIABILITY USING THE VARIETAL DIVERSITY OF CULTIVATED FORMS OF NAKED AND HULLED OATS IN THE INTERCROPPING SYSTEM
Authors: PLĂCINTĂ Domnica , MURARIU Danela
Published: May 2022

The research carried out at the Gene Bank in Suceava, Northern Romania, aimed to highlight the phenotypic variability of the germplasm of Avena spp. For this purpose, the morpho-productive traits and resistance to diseases, pests and weeds were analysed. Productivity, diseases and pests, days to heading and days to maturity descriptors of 46 Avena spp. genotypes (naked and hulled oat) with different biological statuses (36 local populations, 10 cultivars), were evaluated by testing in intercropping experiments with small grain cereals and grain legumes. The unidirectional ANOVA analysis generated values that allowed the elaboration of a hierarchy of heterogeneity in the hulled local populations, for some of the analysed characters (one thousand seeds weight/genotype, degree of attack by Puccinia coronata and Oulema melanopa and days to maturity) and these were less in naked forms. There was a high competition of Avena species, regarding weeds in small grain cereal variants and potentially beneficial for nitrogen symbiotic fixation by increasing naked and hulled local oat population productivity in intercropping with fava bean. The Euclidean distance classification of the oat genotypes investigated in the dendrogram distinguished the generated groups, indicating the maximum distance in cluster IV. With high heterogeneity of productivity traits, better resistance to disease and pests, and shorter maturity, members of this cluster could be used to develop genetic mixture programs.

Published: May 2022

La Revolución  Industrial transformó sustancialmente el ámbito de la edificación y con ello  el devenir de la historia arquitectónica,  esto mediante la incorporación de materiales como el hierro y el vidrio, así como con la aplicación de sistemas prefabricados que en menos tiempo,facilitaron la construcción de grandes obras que dieron cobijo a las necesidades de las  nuevas sociedades industrializadas de todo el mundo, particularmente de Europa y de Estados Unidos de América. Diversas tipologías como el puente, la estación, el mercado, la biblioteca, aprovecharon la posibilidad de poder cubrir grandes claros y se dio un salto cuantitativo como no había ocurrido siglos atrás; surgió igualmente una nueva tipología, el pabellón de exposición que históricamente ha aportado grandes proezas a la historia de la arquitectura. Se presenta un análisis descriptivo de este fenómeno desde sus orígenes, su evolución en el tiempo desde las primeras manifestaciones hibridas entre tecnología e historicismo hasta las edificaciones donde se adoptó una estética totalmente industrial a través de ejemplos paradigmáticos que sembraran una vertiente devanguardia que dio posteriormente paso a la consecución de una arquitectura moderna en el siglo XX.
An Overview of Haploid and Double Haploid Production Methods in Wheat
Authors: MAIWAN Noor , YILDIZ Mehtap , SALİH Sana , LUNA Sara
Published: May 2022

For about a century, researchers have been working on haploidy approach. Progressively, they discovered the importance and usefulness of haploids in various research fields. On the other hand, it is suggested that climate change impacts on crop production, especially wheat, requires rapid and efficient methods of plant breeding to produce new cultivars with a sufficient level of biotic and abiotic tolerance to avoid significant production loss. Haploid plants are the source for producing homozygous pure lines and genetic variability for breeding programs. It reduces the time for producing pure and stable forms of new recombination by half in plant breeding. Furthermore, haploids are source for exclusive male plants generation, induction of mutations, stress resistance and tolerance cultivars, cytogenetic studies, and doubled haploid crops. This review presents a brief overview of the haploid wheat production methods and previous successful experiments on producing haploid wheat.
Effects of Traffic Congestion on Shopping Location Choice in the Greater eThekwini Region
Authors: Hawkins-Mofokeng Raymond , Tlapana Tshepo , Ssemugooma Dennis Kasirye
Published: May 2022

Shopping is a key function that characterizes the eThekwini Central Business District (CBD); however, the eThekwini CBD's central position as a favoured shopping center has deteriorated. The CBD's decline in dominance can be ascribed to a decrease in shopping trip frequency as a result of severe urban center traffic congestion, as well as a rise in the establishment of neighbouring shopping outlets in the city's outskirts. This research aims to investigate the impact of traffic congestion on shopping location selection in the eThekwini region.  400 participants were identified and selected using quantitative, non-probabilistic research methodologies, and convenience sampling procedures.  Convenience and accessibility, tenant mix, entertainment, safety, and parking spaces are all significant qualities of a shopping area according to this study. The findings also suggest that the density of traffic congestion influences shoppers' perceptions of shopping location choices. According to the findings of this study, local authorities must analyze and combine all mitigating strategies to remove traffic congestion and restore the CBD's economic vibrancy. In the course of conducting the study, the researchers were constrained by a lack of adequate financial support and time.

This work proposes a comparative study between several provinces in the region of Marrakech Safi concerning the pollution generated by the industrial units of crushing olives, in particular the volume of olive mill wate water (OMWW) and the polluting load. A physicochemical and bacteriological characterization of the OMWW issues from different industrial olive crushing units was also carried out, the result found showed a high polluting power of the OMWW that differs from one unit to another depending on the mode of crushing of the olive, Indeed, the OMWW are very loaded with polyphenols and organic matter. This effluent also has an acidic pH due to the presence of organic acids (phenolic acids, fatty acids). The high electrical conductivity of the OMWW is due to the presence of natural mineral salts and salts used to preserve olives until grinding such as Na+, Cl– and Ca2+ …. A physicochemical and bacteriological characterization of some wells downstream of the industrial units have also realized to study the impact of OMWW on ground water quality, it was found that most of the wells downstream of the oil mills concerned are of good quality.

Published: May 2022

A simple, rapid, fast, accurate, economical and precise UV spectrophotometric method based on simultaneous equations was developed and validated for simultaneous estimation of Omeprazole and Ondansetron in tablet dosage form. Methanol was selected as a solvent for the proposed method. The method involved simultaneous equations using two wavelengths, with one being the λmax of Omeprazole (205 nm) and the other being the λmax of Ondansetron (246 nm). Beer’s law was obeyed in the concentration range of 2 – 12 µg/mL for both drugs with correlation coefficients of more than 0.99. The results of analysis have been validated statistically and by recovery studies as per ICH guidelines. The limit of detection and limit of quantification were found to be 0.29 µg/mL and 0.90 µg/mL for Omeprazole, respectively and 0.07 µg/mL and 0.21 µg/mL, respectively for Ondansetron. The mean percent recovery of triplicate samples at each level for both drugs was 99.48 - 100.3% for Omeprazole and 99.49 - 99.66% for Ondansetron. The assay results are in good agreement with the label claim; hence it could be used in routine analysis of laboratory samples and marketed formulations containing these two drugs.

The liver is the critical organ. Long-term occupational or environmental exposure as well as excessive exposure to lead may cause severe hepatotoxic effects. The widespread use of lead has led to manifold rise in the occurrence of free lead in biological systems and the inert environment. The lead induced hepatotoxicity study was carried out in adult male wister albino rats. Rat doses of Aloe emodin were selected as 100 mg/kg and 200 mg/kg through oral route. After acclimatization, the animals were randomly divided into 4 groups of 8 animals in each and received normal saline, lead acetate, high and low doses of Aloe emodin along with lead acetate respectively for 28 days. Serum enzymes such as AST, ALT, ALP, total bilirubin and lipid levels were measured by semi-autoanalyser. Antioxidants like SOD, Catalase, TBARS and GSH activity were measured in liver tissue homogenate. Remaining livers were subjected for histological examination. Observed results suggested dose dependent beneficial effects for Aloe emodin against lead acetate induced hepatotoxicity and it was concluded that Aloe emodin exhibited dose‑dependent protection against lead induced hepatoxicity.

This work addresses the usage of indicator analysis as a suitable alternative for applications in companies' most diverse business areas. We assumed that companies linked to the technology sector, such as the one in this study, permeate the construction of their organizational culture code and services among some data orientation factors. The perspective of indicators' analysis grows as a knowledge strategy in the company context and harvests each part of the business. This perspective also favors pieces of more significant assertive impact in actions such as increased productivity, cost reduction, and process optimization, such as the application in product and business metrics. The present work comprises the elaboration of the behavioral analysis of indicators related to the user's profiles of the Mettzer platform. This platform works integrated with the module for universities - as an opportunity search platform (Promotion Notices) and in another aspect, combined with the module for students - Text editor for formatting academic works, according to the Brazilian Association of Technical Norms (ABNT). The editor is the product that effectively contributes to the research carried out in this work, whose objective is to analyze the behavior patterns of the users' profiles of this module for possible application in product metrics. This paper is an exploratory, descriptive and qualitative research of a quantitative approach, in which we collected indicators from the text editor database. Our results sought to favor the company in improving actions to build a strategic differential. We obtained an overview of the behavioral relationships of indicators from the subscriber's profiles and test users, which, in turn, presented helpful information for the company and reaffirmed the trend of analyzing indicators as a good source for decision-making.

Authors: de Oliveira Luis Felipe Rosa , Martins Dalton Lopes
Published: May 2022

This article aims to clarify the use of data science techniques in information science by reporting data collection from the digital repositories of entities linked to the Special Secretariat of Culture of Brazil. This process is part of a research project promoted by the Foundation of Research Support of the State of São Paulo and carried out at the University of Brasília by the Network Intelligence Laboratory. The quantitative descriptive methodology applied alludes to extracting, transforming, and data load used in the constitution of data warehouses, in which Python scripts were developed to collect the data. The results indicate how many scripts were needed and how many storage files were generated, in addition to the description of the data collected, denoting a greater use of the web scraping technique, making the collection process more difficult. Thus, the article points out how the current reality of the analyzed Brazilian cultural institutions is far from enabling the aggregation of their digital repositories. At the same time, it points out how data science strategies allow information science professionals to overcome existing technical barriers and promote data analysis and reuse.

The protection of personal data has been discussed worldwide. This topic arises from a digital economy driven by globalization and the advancement of technologies, making it necessary to guarantee the rights of its holders in the decision on what can be done with their data and information. In this way, the General Data Protection Law was created to protect the fundamental rights of freedom and privacy. Given this, the challenge arises for organizations to adapt to meet legal requirements when it comes to data privacy policies. In this context, the present work aims to analyze the main elements that must be considered in implementing a data privacy policy. Through a bibliographic and documentary survey, we seek to discuss data privacy policies and their characteristics, examining the main aspects that characterize privacy and the protection of personal data in Brazil. The results reveal criteria to be met by the Personal Data Privacy Policy, outlining the main elements of a data privacy policy to comply with the law. We concluded that the policy must meet standards established by legislation, but considering the nature of the business.

Several initiatives to create systems that manage the academic production of an institution, country, or area of knowledge have received attention from different fields. Such systems are known by the acronym CRIS (Current Research Information Systems) and aim to aggregate information from other databases to provide reports and consolidated data for researchers to analyze. Therefore, this work presents the development process of the BrCris Platform to provide technological tools to give the Brazilian academic community consolidated data from the national scientific production. This initiative presents itself as an essential data aggregation mechanism, providing views and analysis of critical scientific datasets, especially on Brazilian scientific output. Therefore, making the BrCris Platform available to the scientific community will give several bibliometric studies that a priori would be highly complex in their conception.
