Published: May 2022

According to the latest data on the number of inmates per technical implementation unit at the Gorontalo Regional Office, the Gorontalo Class IIA Penitentiary has 585 correctional inmates (or WBP) with a capacity of 330 people. It was found that the prison has an overcapacity of 77%. A number of problems in the penitentiary, such as riots, the escape of inmates, and drug trafficking, are often found. It is caused by the problem of overcapacity, which causes inoptimality of services, supervision, and the entire system implementation. Therefore, it is necessary to rebuild a new prison that can accommodate the entire WBP and is equipped with facilities for the self-development of the WBP. The present research collected secondary data and primary data that can support the process of compiling references for the design of fish landing ports in Gorontalo City. Furthermore, it proceeded with site analysis and building analysis.The results show that the design of Gorontalo Class IIA Penitentiary with the Paradox approach aims to create a closed prison atmosphere for the inmates to reflect on their misconducts and wrongdoings. Meanwhile, the availability of space programs that focus on coaching contributes to create the atmosphere of self-development and self-improvement for the inmates.

A comparative study of multiple imputation and subset correspondence analysis in dealing with missing data
Authors: Hendry G. M. , Zewotir T. , Naidoo R. N. , North D.
Published: May 2022

Methods: Multiple imputation and subset correspondence analysis are applied to a set of child asthma data that is mainly categorical and suffers from non-response. Differences in the methods and in the outcomes they produce are studied. In addition, the inclusion of interactions in a subset correspondence analysis is illustrated. Results: Despite the vast differences in the two approaches, they yielded similar results in the identification of genetic, environmental and socio-economic factors that affect childhood asthma. A number of exposure related variables were found to be associated with the greater severity of asthma. It was also found that a finer distinction between the asthma severity levels and their associations with factors was possible with a subset correspondence analysis, compared to the multiple imputation approach. Conclusions: Both multiple imputation and subset correspondence analysis were able to identify several factors associated with childhood asthma while at the same time successfully managing the missing data. This offers the researcher a choice to select the method that best suits his/her study. Keywords: Missing data, Multiple imputation, Subset correspondence analysis

Published: May 2022

In this paper we model competing risks, default and early settlement events, in the presence of long term survivors and compare survival and logistic methodologies. Cause specific Cox regression models were fitted and adjustments were made to accommodate a proportion of long term survivors. Methodologies were compared using ROC curves and area under the curves. The results show that survival methods perform better than logistic regression methods when modelling lifetime data in the presence of competing risks and in the presence of long term survivors.

CAN ENVIRONMENTAL SUSTAINABILITY BE ACHIEVED IN OECD COUNTRIES? PANEL ESTIMATION OF ENVIRONMENTAL KUZNETS CURVE THEORY
Authors: Konya Sevilay
Published: May 2022

The relationship between the environment and the economy is one of the most frequently encountered issues recently. One of the problems that countries have faced recently is environmental sustainability. Therefore, this study is purposed to examine the relationship between environmental and economic variables. In the example of 24 OECD member countries, the entity of Environmental Kuznets curve theory is examined in the inverse U-link between per capita GDP and per capita carbon dioxide emissions. We analyzed the inverted U-link between CO2 emissions and per capita GDP in annual balanced panel data covering the period 1980–2014. Westerlund’s cointegration test was used for analysis. For long-term parameter estimation, PMG (Pooled Mean Group) estimator methods were applied. Dumitrescu and Hurlin Granger causality test was performed to specify causal connections. As a result of the study, it is pointed out that first of all, electricity consumption has a positive and significant effect on CO2 emissions in the long run. Secondly, our findings show that environmental degradation is in an inverted U shape in the Environmental Kuznets Curve hypotheses. That is to say, results were obtained verifying the existence of the Environmental Kuznets Curve theory. Eventually, bidirectional causal links are observed between CO2 emissions and economic growth and between CO2 emissions and electricity consumption.
THERMOLYSIS OF MEDICAL PLASTIC WASTES USING ZEOLITE A CATALYST-KINETIC STUDY, EXPERIMENTAL OPTIMISATION AND VALIDATION
Authors: Das Amar Kumar , Rout Saroj Kumar , Panda Achyut Kumar
Published: May 2022

This work reports the thermo-catalytic conversion of medical plastic wastes to fuel oil using the detergent grade Zeolite A as the catalyst. The effect of catalyst on the pyrolysis is ascertained from the kinetic data obtained from thermogravimetric analysis assuming it to be a first-order reaction. A significant reduction in activation energy of the thermal degradation reaction is found in presence of the Zeolite A catalyst. The pyrolysis runs were performed at different temperatures from 400–550 °C in a stainless-steel batch reactor system to obtain an optimum condition for suitable waste to energy process. The highest oil yield of 79% was obtained at 500 °C with 10% catalyst concentration. The thermogravimetric analysis and the batch pyrolysis experimental result indicated a promising effect of the catalyst in terms of the enhanced rate of reaction and conversion. The oil fraction obtained in the optimum condition of catalytic pyrolysis was analysed for its composition and fuel properties. It confirmed the presence of branched alkane and alkene with composition C10–C18. Again, the fuel properties of the oil such as specific gravity (0.793), viscosity (3.75Cst@ 30 °C), and flash point (<11 °C) resemble that of the petro fuels. Neural Networks (NNs) are used to recognize patterns, and relationships in data and validate the experimental results of this reaction and the results indicate that the use of ANN in thermo-catalytic degradation of medical waste to fuel oil is a feasible option that should be considered for real-time applications.
Predicting the Exoplanet Yield of the TESS Prime and Extended Missions through Years 1–7
Authors: Kunimoto Michelle , Winn Joshua , Ricker George R. , Vanderspek Roland K.
Published: May 2022

The Transiting Exoplanet Survey Satellite (TESS) has discovered ∼5000 planets and planet candidates after 3.5 yr. With a planned second Extended Mission (EM2) spanning Years 5–7 on the horizon, now is the time to revise predictions of the TESS exoplanet yield. We present simulations of the number of detectable planets around 9.4 million AFGKM stars in the TESS Candidate Target List v8.01 through 7 yr of observations. Our simulations take advantage of improved models for the photometric performance, temporal window functions, and transit detection probability. We estimate that 4719 ± 334 planets should be detectable with the Prime Mission alone (Years 1–2), and another 3707 ± 209 should be detectable across the current Extended Mission (Years 3–4). Based on a proposed pointing scenario for EM2, we predict that TESS should find another 4093 ± 180 planets, bringing the total TESS yield to 12,519 ± 678. We provide our predicted yields as functions of host star spectral type, planet radius, orbital period, follow-up feasibility, and location relative to the habitable zone. As TESS continues, new planets will be progressively smaller, with longer orbital periods, and will orbit fainter stars. Half of the planets found in EM2 will be smaller than 4 R
⊕, and over 1200 will have orbital periods longer than 20 days, effectively doubling the TESS yields of both kinds of planets. The number of small (<2 R
⊕) habitable-zone planets will also double, bringing the total TESS yield to 18 ± 5. We also compare our predictions to the actual Prime Mission yield, finding good agreement.

Authors: Beiersdorfer Peter , Gu Ming Feng
Published: May 2022

Laboratory measurements of O vi K-shell emission lines are presented that are situated near the O viii Lyα line at 19 Å. The data provide additional rest-frame references for velocity determinations based on absorption features in the spectra of warm absorbers in active galactic nuclei and other astrophysical objects. They also provide benchmarks for testing atomic structure calculations of energy levels with electrons in a high principal quantum number (n = 3, 4). Excellent agreement is found with our calculations using the many-body perturbation theory method, and we provide a complete listing of the O vi energy levels calculated with this approach.
Stumbling over Planetary Building Blocks: AU Microscopii as an Example of the Challenge of Retrieving Debris-disk Dust Properties
Authors: Arnold Jessica A. , Weinberger Alycia J. , Videen Gorden , Zubko Evgenij S.
Published: May 2022

We explore whether assumptions about dust grain shape affect the resulting estimates of the composition and grain size distribution of the AU Microscopii (AU Mic) debris disk from scattered-light data collected by Lomax et al. The near edge-on orientation of the AU Mic debris disk makes it ideal for studying the effect of the scattering phase function on the measured flux ratios as a function of wavelength and projected distance. Previous efforts to model the AU Mic debris disk have invoked a variety of dust grain compositions and explored the effect of porosity, but did not undertake a systematic effort to explore a full range of size distributions and compositions to understand possible degeneracies in fitting the data. The degree to which modeling dust grains with more realistic shapes compounds these degeneracies has also not previously been explored. We find differences in the grain properties retrieved depending on the grain shape model used. We also present here our calculations of porous grains of size parameters x = 0.1 to 48 and complex refractive indices (m = n + iκ) ranging from n = 1.1 to 2.43 and k = 0 to 1.0, covering multiple compositions at visible and near-infrared wavelengths such as ice, silicates, amorphous carbon, and tholins.
The Improved Amati Correlations from Gaussian Copula
Authors: Liu Yang , Chen Fuyong , Liang Nan , Yuan Zunli , Yu Hongwei , Wu Puxun
Published: May 2022

In this paper, we present two improved Amati correlations of gamma-ray burst (GRB) data via a powerful statistical tool called copula. After calibrating with the low-redshift GRB data, the improved Amati correlations based on a fiducial Λ cold dark matter (ΛCDM) model with Ωm0 = 0.3 and H
0 = 70 km s−1 Mpc−1, and extrapolating the results to the high-redshift GRB data, we obtain the Hubble diagram of GRB data points. Applying these GRB data to constrain the ΛCDM model, we find that the improved Amati correlation from copula can give a result well consistent with Ωm0 = 0.3, while the standard Amati and extended Amati correlations do not. This results suggest that when the improved Amati correlation from copula is used in the low-redshift calibration method, the GRB data can be regarded as a viable cosmological explorer. However, the Bayesian information criterion indicates that the standard Amati correlation remains to be favored mildly since it has the least model parameters. Furthermore, once the simultaneous fitting method rather than the low-redshift calibration one is used, there is no apparent evidence that the improved Amati correlation is better than the standard one. Thus, more work needs to be done in the future in order to compare different Amati correlations.
Assuming Ionization Equilibrium and the Impact on the Lyα Forest Power Spectrum during the End of Reionization at 8 ≥ z ≥ 5
Authors: Kušmić Samir , Finlator Kristian , Keating Laura , Huscher Ezra
Published: May 2022

We explore how the assumption of ionization equilibrium modulates the modeled intergalactic medium at the end of the hydrogen epoch of reionization using the cosmological radiation hydrodynamic Technicolor Dawn simulation. In neutral and partially ionized regions where the metagalactic ultraviolet background is weak, the ionization timescale t
ion ≡ Γ−1 exceeds the Hubble time. Assuming photoionization equilibrium in such regions artificially boosts the ionization rate, accelerating reionization. By contrast, the recombination time t
rec < t
ion in photoionized regions, with the result that assuming photoionization equilibrium artificially increases the neutral hydrogen fraction. Using snapshots in the range 8 ≥ z ≥ 5, we compare the predicted Lyα forest (LAF) flux power spectrum with and without the assumption of ionization equilibrium. Small scales (k > 0.1 rad s km−1) exhibit reduced power from 7 ≤ z ≤ 5.5 in the ionization equilibrium case, while larger scales are unaffected. This occurs for the same reasons: ionization equilibrium artificially suppresses the neutral fraction in self-shielded gas and boosts ionizations in voids, suppressing small-scale fluctuations in the ionization field. When the volume-averaged neutral fraction drops below 10−4, the signature of nonequilibrium ionizations on the LAF disappears. Comparing with recent observations indicates that these nonequilibrium effects are not yet observable in the LAF flux power spectrum.
Low-lying Dipole Resonances in FeCN−: A Viable Formation Pathway for FeCN− in Space
Authors: Barik Saroj , Kumar Kanakati Arun , Dutta Saurav , Ranjan Behera Nihar , Kumar Kushawaha Rajesh , Aravind G.
Published: May 2022

A low-lying resonance in FeCN− anion was identified through abrupt changes in the spectral dependence of the photoelectron angular distribution. Non-Franck–Condon transitions from the resonance to the neutral FeCN (4Δ), and the corresponding photoelectron angular distributions revealed that the resonance is a dipole scattering state. Significant thermionic electron emission was observed in the resonant photoelectron spectra, indicating a strong coupling of the resonance with the ground state of this triatomic anion and its competition over autodetachment. This low-lying resonance is identified to be an efficient pathway for the formation of FeCN− anion in the outer envelope of IRC+10216. The results in general reveal formation pathways in space for anions with low-lying resonances and large permanent dipole moment.
Résilience des systèmes électriques face au changement climatique

Published: May 2022

La question de la résilience des systèmes électriques face aux risques météo-climatiques est une question fondamentale pour la sécurité de l’alimentation en électricité et pour assurer une fourniture de qualité. Les systèmes électriques actuels ont été développés sur la base de référentiels climatiques issus de l’observation historique des phénomènes météo-climatiques. Le changement climatique en cours nous conduit à réinterroger la pertinence de nos référentiels à l’aune des évolutions en cours du climat et des projections climatiques futures réalisées dans le cadre des travaux du GIEC. Dans cet article, nous abordons l’exemple du système électrique français sur la base des études menées par EDF R&D dans le but de caractériser les évolutions du climat et leurs impacts potentiels sur le système électrique, avant de nous intéresser à la démarche d’adaptation engagée en son sein par le groupe EDF.

Predicting 31- to 60-Day Heart Failure Rehospitalization Among Older Women
Authors: Sue-Ling Carolyn Biggs , Jairath Nalini
Published: May 2022

The current study sought to identify social, hemodynamic, and comorbid risk factors associated with 31-to 60-day heart failure (HF) rehospitalization in African American and Caucasian older (aged >65 years) women. A non-equivalent, case-control, quantitative design study using secondary data analysis of medical records from a local community hospital in the Southeast region of the United States was performed over a 3-year period. Relationships between predictor variables and the outcome variable, 31- to 60-day HF rehospitalization, were explored. The full model containing all predictors was not able to distinguish between predictors (χ
2
[21,
N
= 188] = 35.77,
p
= 0.12). However, a condensed model showed that body mass index (BMI) level 1 (<25 kg/m
2
), BMI level 2 (>25 and <30 kg/m
2
), age 75 to 80 years, and those taking lipid-lowering agents were significant predictors. Subtype of HF (reduced or preserved) and race did not predict HF rehospitalization within the specified time period. Multiple comorbid risk factors failed to consistently predict rehospitalization, which may reflect dated HF-specific approaches and therapies. Future studies should evaluate contributions of current targeted post-discharge methods or therapies. [

Systems of semilinear wave equations with multiple speeds in two space dimensions and a weaker null condition
Authors: Cheng Minggang , Katayama Soichiro
Published: May 2022

We consider the Cauchy problem for systems of semilinear wave equations with multiple propagation speeds in two space dimensions. The nonlinear terms are assumed to be cubic and to depend only on first derivatives of the unknowns. The null condition is one of the sufficient condition for the small data global existence for the single-speed case, and it is extended to the multiple-speed case by many authors. Recently, various weaker sufficient conditions for the small data global existence were obtained for the single-speed case. In this paper, we introduce the multiple-speed version of one of such weaker null conditions, and we show the small data global existence. The asymptotic behavior of global solutions is also investigated through associated systems of ODEs called the reduced systems.

In addition, some numerical examples are shown to verify the correctness and novelty of the theoretical results.
Design and protection of microgrid clusters: A comprehensive review
Authors: Sampath Ediriweera W. E. P. , Lidula N. W. A.
Published: May 2022

A microgrid is a concept that has been developed with the increasing penetration of distributed generators. With the increasing penetration of distributed energy resources in the microgrids, along with advanced control and communication technologies, the traditional microgrid concept is being transited towards the concept of microgrid clustering. It decomposes the distribution system into several interconnected microgrids, effectively reducing problems such as voltage rise, harmonics, poor power factor, reverse power flow and failure of the conventional protection schemes. Microgrid clusters effectively coordinate power sharing among microgrids and the main grid, improving the stability, reliability and efficiency of the distribution network at the consumption premises. Despite the evident benefits of microgrid clusters to the consumers and the electrical utility, there are challenges to overcome before adopting the microgrid cluster concept. This paper is aimed at critically reviewing the challenges in design aspects of microgrid clustering. Categorization of multi-microgrids into different architectures based on the layout of the interconnections, evaluation of reported control techniques in microgrid clustering and multi-microgrid protection aspects are presented, highlighting the possible areas of future research that would improve the operational aspects of microgrid clusters.
Existence of solutions for a coupled Schrödinger equations with critical exponent
Authors: Qian Xiaoyong , Wang Jun , Zhu Maochun
Published: May 2022

In this paper we study the existence of multiple nontrivial solutions of the coupled Schrödinger system with external sources terms as perturbations. This type of the system arises from Bose-Einstein condensate. As these external sources terms are nonlinear functions and small in some sense, we use fibre map to divide the Nehari manifold into threes parts, and then prove the existence of a nontrivial ground state solution and a bound state solution.
Linear instability of periodic orbits of free period Lagrangian systems
Authors: Portaluri Alessandro , Wu Li , Yang Ran
Published: May 2022

Minimizing closed geodesics on surfaces are linearly unstable. By starting with this classical Poincaré's instability result, in the present paper we prove a result that allows to deduce the linear instability of periodic solutions of autonomous Lagrangian systems admitting an orbit cylinder (condition which is satisfied for instance if the periodic orbit is transversally non-degenerate) in terms of the parity properties of a suitable quantity which is obtained by adding the dimension of the configuration space to a suitably defined spectral index. Such a spectral index coincides with the Morse index of the periodic orbit seen as a critical point of the free period action functional in the case the Lagrangian is Tonelli, namely fibrewise strictly convex and superlinear, and it encodes the functional and symplectic properties of the problem.

The main result of the paper is a generalization of the celebrated Poincaré 's instability result for closed geodesics on surfaces and at the same time extends to the autonomous case several previous results which have been proved by the authors (as well as by others) in the case of non-autonomous Lagrangian systems.
Intersubjectivity and Virtual Practice in Courses Teaching
Authors: Yang Jianhua , Jiang Chen
Published: May 2022

Based on the intersubjectivity during the teaching of teachers and the learning of students, this study explores the application of intersubjectivity and virtual practice teaching in courses teaching. By studying the current situation of intersubjectivity, virtual practice teaching, and teaching in courses teaching in China, this study designs the immersive virtual practice teaching stage from the perspective of practice according to the connotation of intersubjectivity and its application in courses teaching in colleges and universities. In the stage of immersive virtual practice teaching, by determining the beneficiaries of the course, designing the teaching objects, analyzing the teaching pain points, and designing and optimizing the teaching thinking, the HMM-FNN gesture recognition model was used to identify the gestures operated by the teachers and students in the process of immersive virtual practice teaching. The model further analyzed the advantages of virtual reality technology during the process of courses teaching in view of gesture recognition in the process of courses teaching. Empirical results show that this method can effectively prolong the students’ memory of courses teaching and greatly improve the interactive range of teaching resources. The lowest loss value of gesture recognition between the teachers and students is only 0.4, and virtual practice teaching has strong application. After application, the number of students who fail to pass the examinations dropped significantly, which can effectively improve the scores of students.
An Escalated Performance Aware Approach for Cumulative Effectiveness in Mobile Ad-Hoc Networks
Authors: Brown Karl
Published: May 2022

In order to provide secure communication between mobile nodes in a hostile environment, security has become a top priority. There are a variety of nontrivial difficulties to security design in mobile ad hoc networks because of its unique properties, such as open peer to peer network architecture and shared wireless medium. Building multi-layered security systems that provide broad coverage while still delivering optimal network performance makes perfect sense in light of these problems. Specifically, in this study, we address the basic issue of maintaining the multi-hop network connectivity between mobile nodes in a Mobile Ad Hoc Networks (MANET). There are a number of security concerns that need to be addressed in order to safeguard the multihop wireless channel's MANET connection and network layer activities when delivering packets. We go through these difficulties and possible solutions in this paper. Complete security solutions should cover both layers and include the prevention, detection and response aspects of the three components of the security system. Providing secure communication between mobile nodes in a hostile environment has become a top priority. For example, the open peer-to-peer architecture, shared wireless medium, resource limits, and high dynamic network topology of mobile ad hoc networks provide a variety of nontrivial security design difficulties. The work integrates the effectual approach with the integrity and performance aware implementation for the Mobile Adhoc Networks.

While the national prevalence of stunting in Indonesia has decreased, the level remains high in many districts/cities and there is significant variation. This ecological study employed aggregated data from the Basic Health Research Report and the District/City Poverty Data from 2018. We investigated the determinants of stunting prevalence at the district/city level, including autocorrelation applying the spatial autoregressive (SAR) model. The analyses revealed stunting prevalence above the national average in 282 districts/cities (54.9%), i.e. ≥30% in 297 districts/cities (57.8%) and ≥40% in 91 districts/cities (17.7%). Autocorrelation was found between Sumatra, Java, Sulawesi as well as Bali, East Nusa Tenggara and West Nusa Tenggara (Bali NTT NTB). The SAR modelling revealed the following variables with significant impact on the stunting prevalence in various parts of the country: closet defecation, hand washing, at least four antenatal care visits during pregnancy, poverty, immunisation and supplementary food for children under 5 years.

The tick Ixodes ricinus is widely distributed across Europe and is responsible for the transmission of several pathogens to humans and animals. In this study, we used a knowledge-based method to map variations in habitat suitability for I. ricinus ticks throughout continental France and Corsica. The multi-criteria decision analysis (MCDA) integrated four major biotic and abiotic factors known to influence tick populations: climate, land cover, altitude and the density of wild ungulates. For each factor, habitat suitability index (HSI) values were attributed to different locations based on knowledge regarding its impact on tick populations. For the MCDA, two methods of factor combination were tested, additive and multiplicative, both which were evaluated at the spatial scales of departments and local municipalities. The resulting habitat suitability maps (resolution=100x100 m) revealed that conditions are suitable for I. ricinus over most of France and Corsica. Particularly suitable habitats were located in central, north-eastern and south-western France, while less-suitable habitats were found in the Mediterranean and mountainous regions. To validate the approach, the HSI scores were compared to field data of I. ricinus nymph abundance. Regardless of scale, the correlation between abundance indicator and HSI score was stronger for the additive than for the multiplicative approach. Overall, this study demonstrates the value of MCDA for estimating habitat suitability maps for I. ricinus abundance, which could be especially useful in highlighting areas of the tick’s distribution where preventive measures should be prioritised.

Published: May 2022

The history of the Labin region in Croatia includes intensive industrial development with repercussions of pollution on environment and health. Assuming that prolonged exposure to polluted environments causes qualitative changes in mortality, the aim was to analyse the mortality characteristics of the population of the Labin Region for the 1968-2008 period based on data from the Croatian Bureau of Statistics. Public health and social opportunities in this geographical area carry a long-term burden of exposure to an industrial polluted environment with outcomes expressed by mortality or/and morbidity in the population. This study includes data on 11,903 deaths, most of which due to diseases of the circulatory, respiratory and digestive systems as well as neoplasms. In the third and fourth decade of the study period, a group of neoplasms showed significant increases, while the increase in respiratory diseases were more gradual. The female population died mostly from diseases of the circulatory and endocrine system as well as neoplasms, while the male population mainly died from diseases of the digestive system and external causes. This research provides guidelines that could create better public health, raising the quality of life and contribute to a future environmental protection in local communities by targeted policies.

Published: May 2022

Cardiovascular diseases (CVDs) have been identified as the leading cause of morbidity and mortality among people living with human immunodeficiency virus (PLHIV). However, it is evident that there is a lack of effective surveillance and monitoring of CVDs. Salient side-effects of antiretroviral therapy (ART) exacerbate pre-existing co-morbidities, hence the need for CVDs and its predictors to be monitored closely to ensure life-long care. Personal health records play a crucial role in the field of health information extraction because of their factuality and reliability. The current study assessed the predictors associated with CVDs among PLHIV initiated on ART in the Khomas health district in Namibia A cross-sectional quantitative descriptive study was conducted to extract CVDs predictors from 529 patient care booklets (PCBs) between 2004 and 2018 at purposely selected health facilities in Khomas health district. Data was matched with the electronic Patient Monitoring System(ePMS) and statistical analyses were performed. The study found that prominent CVDs predictors were found to be greatly prevalent among PLHIV initiated on ART with an adjusted variation (p0.001). The mean ± SD age of all participants was 38.10, ± range 64 and 55.1% of them were males and 44.9% were females. Data from this study suggest that high blood pressure, obesity, smoking, and alcohol use are greatly prevalent among PLHIV, particularly among males. Systems that provide accurate information, early screening with subsequent treatment for PLHIV, is recommended by this study.

Previous pandemics have had significant impact on psychological well-being of front-line health care workers. Issues such as fear of contracting the disease, high workload as a result of high numbers of infected cases, increased job stress and unavailability of personal protective equipment have been implicated in development of psychological distress in this subset of individuals. The aim of the present paper is to describe psychobehavioral responses of health care workers and potential predictors of emotional response at onset of COVID-19 outbreak in Nigeria. Cross-sectional web-based survey and 7-item Generalized Anxiety Disorder Questionnaire (GAD-7) were administered anonymously to 444 respondents comprising various categories of frontline healthcare workers. Stepwise multiple linear regression was used to determine predictors of anxiety scores. Participants were mostly young adults (mean age 38 years), females (57%), living with a partner (78.2%) and medical doctors (56.8%). Restrictions in clinical activities and use of hand sanitizers were commonest precautionary behaviors. Commonest emotional responses were anger and despair (27.0% and 25.7%), respectively. About 42.8% had clinically significant anxiety symptoms with highest burden among nurses. Perception of likelihood of 2nd wave (p=0.03), self-preparedness (p=0.04), gender (p=0.01) and cadre (p=0.02) were significant predictors of emotional response of anxiety. Study findings highlighted diverse psychological reactions of health care workers with a large proportion screening positive for significant anxiety symptoms. This has implications for planning a comprehensive psychosocial response to COVID-19 pandemic and for future pandemics among frontline health care workers in lowresource settings.

Dengue is now a major health concern in sub-Saharan Africa. Understanding the influence of local meteorological factors on the incidence of dengue is an important element for better prediction and control of this disease. This study aims to assess the impact of meteorological factors on dengue transmission in the central region of Burkina Faso. We analyzed the lagged effects of meteorological factors on the weekly incidence of dengue from 2017 to 2019 in the central region of Burkina Faso using a General Additive Model. The results show that maximum and minimum temperature, relative humidity, and wind speed have a significant non-linear effect on dengue cases in the region with 83% of case variance explained. The optimal temperature that increases dengue cases was 27°C to 32°C for the maximum temperature and 18°C to 20°C for the minimum temperature with a decrease beyond that. The maximum temperature shifted by six weeks had the best correlation with dengue incidence. The estimated number of dengue cases increases as the maximum relative humidity increases from 15 to 45% and then from 60 to 70%. In general, an increase in daily wind speed is estimated to decrease the number of daily dengue cases. The relationship between rainfall and dengue cases was not significant. This study provides local information about the effect of meteorological factors on dengue that should help improve predictive models of dengue cases in Burkina Faso and contribute to the control of this disease.
Delivering together: A framework for sustainable ownership of early warning and health emergency surveillance technologies in low- and middleincome countries

Previous health and natural disasters have all had a significant impact on human life. However, there is a consensus that the technological advances of our time would have allowed us to better understand and respond to these situations in a more holistic manner. Early Warning and Health Emergency Surveillance technologies are therefore more than essential for improved proactivity. While in developed countries, their implementation is facilitated by the existence of proven mechanisms, this is not often the case in low and middle-income countries. Our practical experience in deploying Early Warning and Health Emergency Surveillance systems in resource-constrained environments led us to develop and propose an approach that is intended to be effective in the execution of such interventions. When implemented in low and middle-income countries, our approach, which promotes the Bottom-to-Top concept, has succeeded in federating and strengthening all the forces in the public, private and international development sectors around the implementation of these crucial technologies for better emergency management, especially in health. Engaging all stakeholders, developing an inclusive modus operandi, promoting a sustainable strategy, and effectively empowering recipients in a coordinated manner is the recipe for the successful implementation of such technologies in low and middle-income countries.
A Prospective, Noncomparative, Study to Evaluate the Efficacy and Safety of Sphincter saving Distal Laser Proximal Ligation Surgery in Complex Fistula-In-Ano
Authors: Porwal Ashwin , Gandhi Paresh , Kulkarni Deepak
Published: May 2022

Background

Distal laser proximal ligation technique (DLPL) is a minimally invasive sphincter-saving surgery which addresses the inter sphincteric space, which is the root cause of complex fistula.

Objective

To evaluate efficacy and safety outcomes of new technique.

Design

A prospective, noncomparative.

Settings

A single-center study.

Patients

Complex fistula-in-ano cases were included. Patients with uncomplicated fistula, inflammatory bowel disease, Chronic immunosuppressive treatment, and cancer were excluded.

Interventions

Laser debridement of fistula tract by use of Radial Fiber with 1470 nm Diode laser at a power of 10W and proximal Ligation technique.

Outcome Measures

Data were collected prospectively on effectiveness (disease severity, ODSscore, hospitalization, time to resume routine), safety (morbidity, adverse outcomes), Wexner incontinence score and quality of life score before surgery and after surgery at week 6, at 6 months and 12 months physically and thereafter telephonically for 2 years. Outcomes other than overall complete healing were considered as failure.

Results

683 patients underwent DLPL, predominantly male with a median age of 41.06 years (range, 11-86y). The overall success rate was 98.98%with a minimum long term follow-up period of 30 months. Complete healing time was average 10 weeks for most of the cases. No case reported permanent(major or minor) anal incontinence. The difference between quality of lifescore wasstatistically highly significant (p<0.001).

Limitations

Single-institution and noncomparative data.

Conclusion

DLPL is a minimally invasive, sphincter saving surgery for complex fistula.
Hair Oils

Published: May 2022

Hair oils are used all over the world since time immemorial; however, their exact effect on the hair and scalp remains obscure. They are usually easily accessible and are inexpensive. A wide variety of oils have been used and newer ones are coming up every day. The primary function of most of the hair oils is to act like an emollient but the unique characteristics of various hair oils suggests its action just more than emollient action. This article focuses on the different types of hair oils and their possible beneficial effects on the hair. Dermatologists need to be aware of the effects of hair oils and their usage.
Psoriasiform skin reaction due to Brazilian keratin treatment

Published: May 2022

Introduction:

Hair straightening products like the Brazilian Keratin Treatment (BKT) contain high concentrations of formaldehyde, and its use is associated with adverse effects. In 2016, seven cases of eczema-like psoriasiform skin reaction secondary to BKT were described for the first time. We aim to investigate the clinical characteristics and dermatoscopic findings of patients with psoriasiform skin reactions due to BKT.

Materials and Methods:

A cross-sectional study was performed from October 2017 to June 2020. Patients who developed erythema and scales on the scalp following the use of BKT were included. Age, sex, number of BKTs, time elapsed between BKT and the skin reaction, pull test, and dermatoscopic findings were investigated. Descriptive and inferential statistics were used.

Results:

We found 43 patients with a mean age of 35 ± 10 years, predominantly females in 42 (98%) cases. The mean number of BKTs was 2 ± 2. The mean length of time elapsed to present the reaction was 12 ± 17 months and this was related to the number of BKTs (P = 0.01). The pull test was positive in 37 (86%) patients. The most frequent dermatoscopic findings were perifollicular scales in 42 (98%), red patches in 35 (81%), and peripilar desquamation resembling the outer skin of an onion bulb in 32 (74%).

Conclusion:

Hair straightening products are widely used and the psoriasiform skin reaction that develops afterward might be underdiagnosed. It is important to investigate the background of BKT in conjunction with the clinical and dermatoscopic findings suggestive of this cutaneous reaction.
