COMPARISON OF INTERMITTENT BOLUS AND CONTINUOUS INFUSION OF 0.1% LEVOBUPIVACAINE WITH FENTANYL FOR EPIDURAL LABOR ANALGESIA
Objectives: This study was carried out to compare intermittent bolus and continuous infusion for epidural labor analgesia in terms of total dose requirement of local anesthetic and quality of analgesia as primary objective. Secondary objective was level of sensory block, motor block, hemodynamic variables, mode of delivery, duration of second stage, neonatal outcome, side effects, and postpartum complications.
Methods: Eighty women of ASA physical status I or II, with single pregnancy, cephalic presentation and cervical dilatation 3–5 cm, that is, during active labor were included in the study. Patients were randomly divided into two groups. In Group A, a bolus of 8 ml of 0.1% levobupivacaine (plain) with fentanyl 2 mcg/ml was given every hour and in Group B, an infusion of 0.1% levobupivacaine (plain) with fentanyl 2 mcg/ml at 8 ml/h was given. Pain scores using visual analog scale and verbal rating score, additional bolus requirement and total dose of local anesthetic, motor blockade, fetal and neonatal outcome, mode of delivery, and duration of second stage were recorded and compared. Side effects and postpartum complications if any were documented.
Results: Additional bolus requirement and total dose of local anesthetic were significantly high in Group B (45.60±6.67 mg) as compared to Group A (34.20±5.58 mg). There was no difference in the quality of analgesia, neonatal outcome, mode of delivery, duration of second stage, side effects, and complications.
Conclusion: Intermittent epidural bolus is better in terms of less drug consumption and less number of additional bolus requirement
E-Learning during COVID-19 outbreak : cloud computing adoption in Indian public universities
In the COVID-19 pandemic situation, the need to adopt cloud computing
(CC) applications by education institutions, in general, and higher education
(HE) institutions, in particular, has especially increased to engage students in an
online mode and remotely carrying out research. The adoption of CC across various
sectors, including HE, has been picking momentum in the developing countries
in the last few years. In the Indian context, the CC adaptation in the HE
sector (HES) remains a less thoroughly explored sector, and no comprehensive
study is reported in the literature. Therefore, the aim of the present study is to
overcome this research vacuum and examine the factors that impact the CC adoption
(CCA) by HE institutions (HEIs) in India. The scope of the study is limited to
public universities (PUs) in India. There are, in total, 465 Indian PUs and among
these 304 PUs, (i.e., 65% PUs) are surveyed using questionnaire-based research.
The study has put forth a novel integrated technology adoption framework consisting
of the Technology Acceptance Model (TAM), Technology-Organization-
Environment (TOE), and Diffusion of Innovation (DOI) in the context of the
HES. This integrated TAM-TOE-DOI framework is utilized in the study to analyze
eleven hypotheses concerning factors of CCA that have been tested using
structural equation modelling (SEM) and confirmatory factor analysis (CFA).
The findings reveal that competitive advantage (CA), technology compatibility
(TC), technology readiness (TR), senior leadership support, security concerns,
government support, and vendor support are the significant contributing factors
of CCA by Indian PUs. The study contends that whereas the rest of the factors
positively affect the PUs’ intention towards CCA, security concerns are a significant
reason for the reluctance of these universities against adopting CC. The findings
demonstrated the application of an integrated TAM-TOE-DOI framework to
assess determining factors of CCA in Indian PUs. Further, the study has given
useful insights into the successful CCA by Indian PUs, which will facilitate
eLearning and remote working during COVID-19 or similar outbreak.peer-reviewe
Standardizing primary health care referral data sets in Nigeria : practitioners' survey, form reviews, and profiling of Fast Healthcare Interoperability Resources (FHIR)
Background: Referral linkages are crucial for efficient functioning of primary health care (PHC) systems. Fast Healthcare
Interoperability Resource (FHIR) is an open global standard that facilitates structuring of health information for coordinated
exchange among stakeholders.Objective: The objective of this study is to design FHIR profiles and present methodology and the profiled FHIR resource for
Maternal and Child Health referral use cases in Ebonyi state, Nigeria—a typical low- and middle-income country (LMIC) setting.Methods: Practicing doctors, midwives, and nurses were purposefully sampled and surveyed. Different referral forms were
reviewed. The union of data sets from surveys and forms was aggregated and mapped to base patient FHIR resource elements,
and extensions were created for data sets not in the core FHIR specification. This study also introduced FHIR and its relation to
the World Health Organization’s (WHO’s) International Classification of Diseases.Results: We found many different data elements from the referral forms and survey responses even in urban settings. The
resulting FHIR standard profile is published on GitHub for adaptation or adoption as necessary to aid alignment with WHO
recommendations. Understanding data sets used in health care and clinical practice for information sharing is crucial in properly
standardizing information sharing, particularly during the management of COVID-19 and other infectious diseases. Development
organizations and governments can use this methodology and profile to fast-track FHIR standards adoption for paper and electronic
information sharing at PHC systems in LMICs.Conclusions: We presented our methodology for profiling the referral resource crucial for the standardized exchange of new
and expectant moms’ information. Using data from frontline providers and mapping to the FHIR profile helped contextualize the
standardized profile.peer-reviewe
A survey of detection and mitigation for fake images on social media platforms
Recently, the spread of fake images on social media platforms has become a significant
concern for individuals, organizations, and governments. These images are often created using
sophisticated techniques to spread misinformation, influence public opinion, and threaten national
security. This paper begins by defining fake images and their potential impact on society, including
the spread of misinformation and the erosion of trust in digital media. This paper also examines the
different types of fake images and their challenges for detection. We then review the recent approaches
proposed for detecting fake images, including digital forensics, machine learning, and deep learning.
These approaches are evaluated in terms of their strengths and limitations, highlighting the need
for further research. This paper also highlights the need for multimodal approaches that combine
multiple sources of information, such as text, images, and videos. Furthermore, we present an
overview of existing datasets, evaluation metrics, and benchmarking tools for fake image detection.
This paper concludes by discussing future directions for fake image detection research, such as
developing more robust and explainable methods, cross-modal fake detection, and the integration
of social context. It also emphasizes the need for interdisciplinary research that combines computer
science, digital forensics, and cognitive psychology experts to tackle the complex problem of fake
images. This survey paper will be a valuable resource for researchers and practitioners working on
fake image detection on social media platforms.peer-reviewe
An efficient sound and data steganography based secure authentication system
The prodigious advancements in contemporary technologies have
also brought in the situation of unprecedented cyber-attacks. Further, the
pin-based security system is an inadequate mechanism for handling such
a scenario. The reason is that hackers use multiple strategies for evading
security systems and thereby gaining access to private data. This research
proposes to deploy diverse approaches for authenticating and securing a
connection amongst two devices/gadgets via sound, thereby disregarding the
pins’ manual verification. Further, the results demonstrate that the proposed
approaches outperform conventional pin-based authentication orQR authentication
approaches. Firstly, a random signal is encrypted, and then it is
transformed into a wave file, after which it gets transmitted in a short burst
via the device’s speakers. Subsequently, the other device/gadget captures these
audio bursts through its microphone and decrypts the audio signal for getting
the essential data for pairing. Besides, this model requires two devices/gadgets
with speakers and a microphone, and no extra hardware such as a camera,
for reading the QR code is required. The first module is tested with real-time
data and generates high scores for the widely accepted accuracy metrics,
including precision, Recall, F1 score, entropy, and mutual information (MI).
Additionally, this work also proposes a module helps in a secured transmission
of sensitive data by encrypting it over images and other files. This steganographic
module includes two-stage encryption with two different encryption
algorithms to transmit data by embedding inside a file. Several encryption
algorithms and their combinations are taken for this system to compare the resultant file size. Both these systems engender high accuracies and provide
secure connectivity, leading to a sustainable communication ecosystem.peer-reviewe
Global, regional, and national sex-specific burden and control of the HIV epidemic, 1990-2019, for 204 countries and territories: the Global Burden of Diseases Study 2019
Background: The sustainable development goals (SDGs) aim to end HIV/AIDS as a public health threat by 2030. Understanding the current state of the HIV epidemic and its change over time is essential to this effort. This study assesses the current sex-specific HIV burden in 204 countries and territories and measures progress in the control of the epidemic.
Methods: To estimate age-specific and sex-specific trends in 48 of 204 countries, we extended the Estimation and Projection Package Age-Sex Model to also implement the spectrum paediatric model. We used this model in cases where age and sex specific HIV-seroprevalence surveys and antenatal care-clinic sentinel surveillance data were available. For the remaining 156 of 204 locations, we developed a cohort-incidence bias adjustment to derive incidence as a function of cause-of-death data from vital registration systems. The incidence was input to a custom Spectrum model. To assess progress, we measured the percentage change in incident cases and deaths between 2010 and 2019 (threshold >75% decline), the ratio of incident cases to number of people living with HIV (incidence-to-prevalence ratio threshold <0·03), and the ratio of incident cases to deaths (incidence-to-mortality ratio threshold <1·0).
Findings: In 2019, there were 36·8 million (95% uncertainty interval [UI] 35·1–38·9) people living with HIV worldwide. There were 0·84 males (95% UI 0·78–0·91) per female living with HIV in 2019, 0·99 male infections (0·91–1·10) for every female infection, and 1·02 male deaths (0·95–1·10) per female death. Global progress in incident cases and deaths between 2010 and 2019 was driven by sub-Saharan Africa (with a 28·52% decrease in incident cases, 95% UI 19·58–35·43, and a 39·66% decrease in deaths, 36·49–42·36). Elsewhere, the incidence remained stable or increased, whereas deaths generally decreased. In 2019, the global incidence-to-prevalence ratio was 0·05 (95% UI 0·05–0·06) and the global incidence-to-mortality ratio was 1·94 (1·76–2·12). No regions met suggested thresholds for progress. Interpretation: Sub-Saharan Africa had both the highest HIV burden and the greatest progress between 1990 and 2019. The number of incident cases and deaths in males and females approached parity in 2019, although there remained more females with HIV than males with HIV. Globally, the HIV epidemic is far from the UNAIDS benchmarks on progress metrics.

Measuring routine childhood vaccination coverage in 204 countries and territories, 1980-2019 : a systematic analysis for the Global Burden of Disease Study 2020, Release 1
Background Measuring routine childhood vaccination is crucial to inform global vaccine policies and programme implementation, and to track progress towards targets set by the Global Vaccine Action Plan (GVAP) and Immunization Agenda 2030. Robust estimates of routine vaccine coverage are needed to identify past successes and persistent vulnerabilities. Drawing from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2020, Release 1, we did a systematic analysis of global, regional, and national vaccine coverage trends using a statistical framework, by vaccine and over time. Methods For this analysis we collated 55 326 country-specific, cohort-specific, year-specific, vaccine-specific, and dosespecific observations of routine childhood vaccination coverage between 1980 and 2019. Using spatiotemporal Gaussian process regression, we produced location-specific and year-specific estimates of 11 routine childhood vaccine coverage indicators for 204 countries and territories from 1980 to 2019, adjusting for biases in countryreported data and reflecting reported stockouts and supply disruptions. We analysed global and regional trends in coverage and numbers of zero-dose children (defined as those who never received a diphtheria-tetanus-pertussis [DTP] vaccine dose), progress towards GVAP targets, and the relationship between vaccine coverage and sociodemographic development. Findings By 2019, global coverage of third-dose DTP (DTP3; 81.6% [95% uncertainty interval 80.4-82 .7]) more than doubled from levels estimated in 1980 (39.9% [37.5-42.1]), as did global coverage of the first-dose measles-containing vaccine (MCV1; from 38.5% [35.4-41.3] in 1980 to 83.6% [82.3-84.8] in 2019). Third- dose polio vaccine (Pol3) coverage also increased, from 42.6% (41.4-44.1) in 1980 to 79.8% (78.4-81.1) in 2019, and global coverage of newer vaccines increased rapidly between 2000 and 2019. The global number of zero-dose children fell by nearly 75% between 1980 and 2019, from 56.8 million (52.6-60. 9) to 14.5 million (13.4-15.9). However, over the past decade, global vaccine coverage broadly plateaued; 94 countries and territories recorded decreasing DTP3 coverage since 2010. Only 11 countries and territories were estimated to have reached the national GVAP target of at least 90% coverage for all assessed vaccines in 2019. Interpretation After achieving large gains in childhood vaccine coverage worldwide, in much of the world this progress was stalled or reversed from 2010 to 2019. These findings underscore the importance of revisiting routine immunisation strategies and programmatic approaches, recentring service delivery around equity and underserved populations. Strengthening vaccine data and monitoring systems is crucial to these pursuits, now and through to 2030, to ensure that all children have access to, and can benefit from, lifesaving vaccines.

The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019
Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

The global burden of adolescent and young adult cancer in 2019 : a systematic analysis for the Global Burden of Disease Study 2019
Background In estimating the global burden of cancer, adolescents and young adults with cancer are often overlooked, despite being a distinct subgroup with unique epidemiology, clinical care needs, and societal impact. Comprehensive estimates of the global cancer burden in adolescents and young adults (aged 15-39 years) are lacking. To address this gap, we analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, with a focus on the outcome of disability-adjusted life-years (DALYs), to inform global cancer control measures in adolescents and young adults. Methods Using the GBD 2019 methodology, international mortality data were collected from vital registration systems, verbal autopsies, and population-based cancer registry inputs modelled with mortality-to-incidence ratios (MIRs). Incidence was computed with mortality estimates and corresponding MIRs. Prevalence estimates were calculated using modelled survival and multiplied by disability weights to obtain years lived with disability (YLDs). Years of life lost (YLLs) were calculated as age-specific cancer deaths multiplied by the standard life expectancy at the age of death. The main outcome was DALYs (the sum of YLLs and YLDs). Estimates were presented globally and by Socio-demographic Index (SDI) quintiles (countries ranked and divided into five equal SDI groups), and all estimates were presented with corresponding 95% uncertainty intervals (UIs). For this analysis, we used the age range of 15-39 years to define adolescents and young adults. Findings There were 1.19 million (95% UI 1.11-1.28) incident cancer cases and 396 000 (370 000-425 000) deaths due to cancer among people aged 15-39 years worldwide in 2019. The highest age-standardised incidence rates occurred in high SDI (59.6 [54.5-65.7] per 100 000 person-years) and high-middle SDI countries (53.2 [48.8-57.9] per 100 000 person-years), while the highest age-standardised mortality rates were in low-middle SDI (14.2 [12.9-15.6] per 100 000 person-years) and middle SDI (13.6 [12.6-14.8] per 100 000 person-years) countries. In 2019, adolescent and young adult cancers contributed 23.5 million (21.9-25.2) DALYs to the global burden of disease, of which 2.7% (1.9-3.6) came from YLDs and 97.3% (96.4-98.1) from YLLs. Cancer was the fourth leading cause of death and tenth leading cause of DALYs in adolescents and young adults globally. Interpretation Adolescent and young adult cancers contributed substantially to the overall adolescent and young adult disease burden globally in 2019. These results provide new insights into the distribution and magnitude of the adolescent and young adult cancer burden around the world. With notable differences observed across SDI settings, these estimates can inform global and country-level cancer control efforts. Copyright (C) 2021 The Author(s).
