THE PHILOSOPHY OF HRYHORII SKOVORODA IN THE CONTEXT OF HUMANCENTRISM
Authors: Kremen Vasyl
Published: February 2023

Through the prism of the Ukrainian philosophical thinking issues, the article highlights the philosophical position of Hryhorii Skovoroda, which is based on clarifying the specifics of a particular human personality and focuses on the inner world of a person, the world of the “soul” and “heart”. According to H. Skovoroda, the “philosophy of the heart” is a statement of a new approach to understanding a person, the meaning of his existence and destination in theworld. It is proved that such a cordocentric approach has a long national tradition and was initiated in the early literature of the proto-Ukrainian society of Kyivan Rus. It is substantiated that a characteristic feature of H. Skovoroda’s philosophical system is the joining of a man and the world. This means creating a coherent philosophy that integrates ethics, ontology, philosophical wisdom, and moral behaviour in the philosophical dimension. H. Skovoroda appeals to the “voice of the heart”, which confirms the begin of developing his humancentrism on the national ground and acts as an alternative to the rationalist and objectivist method precisely in defending the fundamental importance, the primacy of the individual and personal, and cultural and multivocal uniqueness of human existence.

DIVIDEND POLICY AND ITS IMPACT ON SHAREHOLDERS’ WEALTH: CASE OF NON-FINANCIAL FIRMS
Authors: Priyan P. K. , Nyabakora Wakara Ibrahimu
Published: February 2023

Purpose: The research is about the effect of dividend policy on shareholders’ wealth for Dar es Salaam Stock Exchange listed non-financial firms in Tanzania from 2005 to 2019.
Design/methodology: The research employs secondary data information from firms’ financial reports as published on the Dar es Salaam Stock Exchange website, using descriptive statistics, panel dynamic least square method, and cointegration analysis to test the association between variables.
Findings: The results show that at 95 percent level of significance, dividend per share have significant positive effects on all proxies for shareholders’ wealth. However, dividend yield has insignificant negative effects on all proxies for shareholders’ wealth. The moderating variable indicates that investment opportunities have positive and significant effects on all the shareholders’ wealth proxies, which is one of the factors that strengthen the relationship between dividend policy and shareholders’ wealth.
Originality/value: This result, being the first study done in Tanzania, apart from helping stakeholders to avoid generalization of findings from developed economies to developing countries, will also help firms’ managers on how to implement shareholders’ wealth-maximizing strategies and capital accumulation for their internal growth. Furthermore, the results will enable potential investors and shareholders to decide whether to invest in certain firms or not, and whether to sell their shares and leave or retain them.

IDENTIFICAÇÃO E MANEJO EMERGENCIAL DA PSICOSE PÓS-PARTO
Authors: SILVA C.J.F , GOMES S.L , VASCONCELOS A.S
Published: February 2023

INTRODUÇÃO: A psicose pós-parto (PP) é um transtorno de humor pós-natal grave que comumente se manifesta como mania aguda, alucinações e depressão. Sob esse viés, a identificação precoce e a rápida intervenção farmacológica se tornam essenciais para a prevenção de eventos graves subsequentes, como suicídio materno e infanticídio. O transtorno supracitado demanda uma avaliação criteriosa do estado geral da paciente, incluindo a necessidade de hospitalização e garantia de segurança para a usuária, além da possibilidade de uso de benzodiazepínicos, antipsicóticos atípicos. Nessa perspectiva, a manutenção do tratamento em termos psicológicos e psicossociais se torna relevante à medida que infere na qualidade de vida das pacientes diagnosticadas com PP e evita a recidiva dos episódios agudos. OBJETIVO: Analisar os aspectos do atendimento de gestantes em episódios psicóticos agudos em ambiente hospitalar, por meio de uma análise da literatura científica entre janeiro de 2018 e julho de 2022. METODOLOGIA: Foram selecionadas publicações no banco de dados PubMed, utilizando-se os descritores: (postpartum psychosis) AND (emergency) AND (pregnant). Ademais, considerando-se o critério de inclusão de publicações dos últimos 5 anos, reduziu-se a pesquisa de 881 para 541 publicações. RESULTADOS: Em um estudo com 13 mulheres de 25 a 44 anos, uma já apresentava diagnóstico de desordem bipolar e 3 foram diagnosticadas posteriormente ao parto. Ademais, em 16 episódios agudos de psicose pós-parto vivenciados por essas mulheres, 94% desses episódios (13) foram manejados por intermédio de internação hospitalar. Outrossim, no que diz respeito à provisão de saúde mental, em 44% dos episódios (7), as mulheres estavam sob os cuidados secundários de uma equipe de saúde, o que demonstra uma baixa presença de continuidade da linha de cuidado na PP. Nessa perspectiva, os principais antipsicóticos utilizados são a lurasidona e o aripiprazol, além da administração de lítio de 6 a 9 meses, a fim de reduzir sintomas da doença, que podem se acentuar se forem conjugados a antidepressivos sem estabilizadores de humor. CONCLUSÃO: Em decorrência da gravidade da PP, é imprescindível a avaliação imediata do estado da paciente e, em alguns casos, a realização de internação hospitalar, como também da administração de medicamentos que visam ao manejo dos quadros agudos de psicose pós-parto. Ademais, faz-se necessária a assistência em saúde para prevenir a agudização e facilitar a recuperação, promovendo, assim, um suporte a longo prazo.

Though the global atmospheres of hot Jupiters have been extensively studied using phase curve observations, the level of time variability in these data is not well constrained. To investigate possible time variability in a planetary phase curve, we observed two full-orbit phase curves of the hot Jupiter WASP-43b at 4.5 μm using the Spitzer Space Telescope, and reanalyzed a previous 4.5 μm phase curve from Stevenson et al. We find no significant time variability between these three phase curves, which span timescales of weeks to years. The three observations are best fit by a single phase curve with an eclipse depth of 3907 ± 85 ppm, a dayside-integrated brightness temperature of 1479 ± 13 K, a nightside integrated brightness temperature of 755 ± 46 K, and an eastward-shifted peak of 10.°4 ± 1.°8. To model our observations, we performed 3D general circulation model simulations of WASP-43b with simple cloud models of various vertical extents. In comparing these simulations to our observations, we find that WASP-43b likely has a cloudy nightside that transitions to a relatively cloud-free dayside. We estimate that any change in WASP-43b’s vertical cloud thickness of more than three pressure scale heights is inconsistent with our observed upper limit on variation. These observations, therefore, indicate that WASP-43b’s clouds are stable in their vertical and spatial extent over timescales up to several years. These results strongly suggest that atmospheric properties derived from previous, single Spitzer phase curve observations of hot Jupiters likely show us the equilibrium properties of these atmospheres.
A uvbyCaHβ CCD Analysis of the Open Cluster Standard, M67, and Its Relation to NGC 752
Authors: Twarog Bruce A. , Anthony-Twarog Barbara J. , Deliyannis Constantine P.
Published: February 2023

Precision CCD uvbyCaHβ photometry is presented of the old cluster, M67, covering one square degree with typical internal precision at the 0.005–0.020 mag level to V ∼ 17. The photometry is calibrated using standards over a wide range in luminosity and temperature from NGC 752 and zeroed to the standard system via published photoelectric observations. Relative to NGC 752, differential offsets in reddening and metallicity are derived using astrometric members, supplemented by radial velocity information. From single-star members, offsets in the sense (M67−NGC 752) are δ
E(b − y) = −0.005 ± 0.001 (sem) mag from 327 F/G dwarfs and δ[Fe/H] = 0.062 ± 0.006 (sem) dex from the combined m
1 and hk indices of 249 F dwarfs, leading to E(b − y) = 0.021 ± 0.004 (sem) and [Fe/H]M67 = +0.030 ± 0.016 (sem) assuming [Fe/H]Hyades = +0.12. With probable binaries eliminated using c
1, (b − y) indices, 83 members with (π/σ

π
) > 50 generate (m − M)0 = 8.220 ± 0.005 (sem) for NGC 752 and an isochronal age of 1.45 ± 0.05 Gyr. Using the same parallax restriction for 312 stars, M67 has (m − M) = 9.77 ± 0.02 (sem), leading to an age tied solely to the luminosity of the subgiant branch of 3.70 ± 0.03 Gyr. The turnoff color spread implies ±0.1 Gyr, but the turnoff morphology defines a younger age/higher mass for the stars, consistent with recent binary analysis and broadband photometry indicating possible missing physics in the isochrones. Anomalous stars positioned blueward of the turnoff are discussed.
On the Spatial Distribution of 13CO Structures within 12CO Molecular Clouds

Published: February 2023

We look into the 2851 12CO molecular clouds harboring 13CO structures to reveal the distribution of the projected angular separations and radial velocity separations between their internal 13CO structures. The projected angular separations are determined using the minimal spanning tree algorithm. We find that ∼50% of the angular separations fall in a narrow range of ∼3′–7′ with a median of ∼5′, and the corresponding radial velocity separations mainly range from ∼0.3 to 2.5 km s−1. The mean and standard deviation of the angular separations of the internal 13CO structures within 12CO clouds appear to be universal, independent of the 12CO cloud angular areas and the counts of their internal 13CO structures. We also reveal a scaling relation between the 12CO cloud angular area and its harbored 13CO structure count. These results suggest there is a preferred angular separation between 13CO structures in these 12CO clouds, considering the distance effects. According to that, we propose an alternative picture for the assembly and destruction of molecular clouds: there is a fundamental separation for the internal structures of molecular clouds, the build-up and destruction of molecular clouds proceeds under this fundamental unit.
The Abundance of Belatedly Habitable Planets and Ambiguities in Definitions of the Continuously Habitable Zone
Authors: Tuchow Noah W. , Wright Jason T.
Published: February 2023

A planet’s history dictates its current potential to host habitable conditions and life. The concept of the continuously habitable zone (CHZ) has been used to define the region around a star most likely to host planets with long-term habitability. However, definitions of the CHZ vary in the literature and often conflict with each other. Calculating the fraction of habitable zone planets in the CHZ as a function of stellar properties, we find that the quality of a star as a host for planets with long-term habitability and biosignatures depends strongly on the formulation of the CHZ used. For instance, older M stars are either excellent or suboptimal hosts for CHZ planets, depending on whether one’s definition of habitability prioritizes the total time spent in the habitable zone or the continuity of habitable conditions from the delivery of volatiles to its current age. In this study, we focus on belatedly habitable zone (BHZ) planets, i.e., planets that enter the habitable zone after formation due to the evolution of their host star. We find that between ∼29% and 74% of planets in the habitable zone belong to this class of BHZ planets, depending on the timescale for the delivery of volatiles. Whether these planets can retain their volatiles and support habitable conditions is unclear. Since BHZ planets comprise a large portion of the planets we expect to survey for biosignatures with future missions, the open question of their habitability is an important factor for mission design, survey strategies, and the interpretation of results.
In Situ Observations of Whistler-mode Waves in Magnetic Reconnection at Mars
Authors: Wang Jing , Yu Jiang , Ren Aojun , Chen Zuzheng , Xu Xiaojun , Cui Jun , Cao Jinbin
Published: February 2023

Whistler-mode waves are one of the most important plasma waves potentially affecting the triggering and development processes of magnetic reconnection. They are widely present in the Earth’s reconnection ion diffusion region but have not yet been reported in Mars’. Based on in situ measurements from MAVEN, the Mars Atmosphere and Volatile Evolution mission, we report for the first time whistler-mode waves in the ion diffusion region at the center of the current sheet in the Martian magnetotail. Simultaneously, pancake electron distributions with high temperature anisotropy are observed. Linear instability analyses imply that these unstable electrons can trigger the observed whistler-mode waves. Such findings not only fill the gap in observations of whistler-mode waves in the magnetic reconnection at Mars but also enrich our understanding of their generation mechanism in the reconnection region at unmagnetized planets.

The heating and acceleration of the solar wind remains one of the unsolved fundamental problems in heliophysics. It is usually observed that the proton temperature T

i
is highly correlated with the solar wind speed V
SW, while the electron temperature T

e
shows anticorrelation or no clear correlation with the solar wind speed. Here, we inspect both Parker Solar Probe (PSP) and WIND data, and compare the observations with simulation results. PSP observations below 30 solar radii clearly show a positive correlation between the proton temperature and the wind speed and a negative correlation between the electron temperature and the wind speed. One year (2019) of WIND data confirm that the proton temperature is positively correlated with the solar wind speed, but the electron temperature increases with the solar wind speed for slow wind, while it decreases with the solar wind speed for fast wind. Using a 1D Alfvén-wave-driven solar wind model with different proton and electron temperatures, we find, for the first time, that if most of the dissipated Alfvén wave energy heats the ions instead of the electrons, a positive T

i
–V
SW correlation and a negative T

e
–V
SW correlation arise naturally. If the electrons gain a small but finite portion of the dissipated wave energy, the T

e
–V
SW correlation evolves with the radial distance to the Sun, such that the negative correlation gradually turns positive. The model results show that Alfvén waves are one of the possible explanations for the observed evolution of the proton and electron temperatures in the solar wind.
Early Galaxy Formation and the Hubble Constant Tension
Authors: McGaugh Stacy S.
Published: February 2023

Tension between local determinations of the Hubble constant and the value found in fits to the cosmic microwave background (CMB) acoustic power spectrum have emerged as finer angular scales (higher multipoles ℓ) have been measured in the latter. Independent observations indicate that massive galaxies emerged at higher redshift than anticipated in the standard ΛCDM structure formation paradigm. If genuine, these early galaxies would cause excess gravitational lensing of the CMB, adding an anomalous source of power at high ℓ. I suggest that accommodating this anomalous source of power in multiparameter fits might be the root cause of the Hubble tension rather than systematics in local measurements.

Published: February 2023

Length and weight relationships (LWR) were estimated for 39 fish species from 30 families from the northwestern Gulf of Mexico. Fish specimens were sampled during four oceanographic campaigns (February and October 2016, June and September 2017) using a shrimp trawl net and benthic sled net in 20 locations at depths that ranged from 43 to 3,608 m. New maximum standard length (SL) was obtained for Cyclothone alba, C. braueri, C. pseudopallida, and Lepophidium brevibarbe. A positive allometric growth was reported in 22 species and 17 showed a negative allometric growth.

Published: February 2023

La pandémie de la COVID-19 et la crise sanitaire et sociale qui en a découlé ont encouragé la conduite d’entretiens semi-directifs par téléphone ou par visioconférence. À partir de trois enquêtes réalisées par des jeunes femmes portant sur l’intime et ayant recours aux entretiens biographiques, cette note méthodologique examine les façons dont l’entretien à distance transforme la nature des matériaux collectés et recompose ce faisant le mode de production de connaissances sociologiques. Elle montre que le distanciel renouvelle les profils sociaux accessibles en ouvrant la voie à des configurations inédites. Elle donne également à voir les atouts de ce dispositif pour accéder à l’intériorité du sujet et souligne son potentiel dans les cas où des positions asymétriques entre enquêteur/rice et enquêté·e dans les rapports de pouvoir (en particulier de genre) sont susceptibles d’entraver la relation d’enquête, risquant dès lors d’appauvrir les connaissances produites.
Does further-mathematics performance predict student's achievement in Physics? A correlational diagnosis in senior secondary schools
Authors: Badmus Olalekan , Jita Loyiso
Published: February 2023

The awareness and application of the knowledge of Further Mathematics transcends the boundary of Physics as a discipline. The need to explore means of improving students’ achievement in physics remains valid in the parlance of research. The use of mathematical knowledge in resolving physics is established in the literature. Over the years, students offer general mathematics and physics at the same time, yet, perform unsatisfactorily in physics. The application of further mathematics in physics and vice versa is evident in the curriculum. This study explored predictively, the correlation in the achievement of students in physics and further-mathematics. Ex post facto research of the co-relation type was employed in the comparison of pro forma of respondents in West African Senior School Certificate examination (WASSCE). Purposive sampling technique was employed in the selection of 103 respondents for the study. PPMC and MANOVA was employed in the analysis of data. The study observed a significant prediction in the achievement of students offering further mathematics and physics. However, gender and school type were not significant influencer the correlation between these two subjects. This study recommended that equal opportunities exist for male and female students, as well as, in public and private schools in these subject areas.
Soil erosion estimation using Erosion Potential Method in the Vjosa River Basin, Albania
Authors: Marko Oltion , Gjipalaj Joana , Profka Dritan , Shkodrani Neritan
Published: February 2023

Soil erosion is a major environmental threat to soil sustainability and productivity with knock-on effects on agriculture, climate change, etc. Factors influencing soil erosion are many and usually divided into natural and human causes. Massive deforestation, intensive agriculture, temperature and wind, rainfall intensity, human activities and climate changes are listed as the main causes of soil erosion. Calculation of the coefficient of soil erosion is very important to prevent the event. One of the methods used worldwide to calculate soil loss and the erosion coefficient is the Erosion Potential Method. In this study, 49 sub-basins of the Vjosa River Basin in Albania were evaluated. Results showed that the phenomenon of erosion is present in all sub-basins, varying from 0.01 to 0.71. Thus, the categorization of soil erosion varies from heavy to very slight erosion. Moreover, the overall sediment yield calculated for the Vjosa River Basin was 2326917 m3/year. In conclusion, the application of the Erosion Potential Method is reliable for evaluating erosion and can further be applied in our country's conditions.
Priorités et stratégies d’un formateur lors de la mise en œuvre d’un jeu de rôles en mathématiques

Published: February 2023

In previous work, we designed, implemented and analyzed a teacher-training scenario based on role-play, which immerses preservice teachers into a situation involving a primary school teacher helping a pupil with some mathematical task (Lajoie et al., 2019). We highlighted some potential offered to the teacher trainer to bring out, in preservice teachers, mathematical, didactic and pedagogical knowledge but we came to the conclusion that making the most of this potential involved demanding work on the part of the teacher trainer. In this paper, we investigate this dimension within the activity theory field, more precisely the way a teacher trainer who did not participate in the design of the scenario implements it, in particular the way she manages the collective discussion phases.
Une analyse des pratiques de formation initiale l’algorithmique et à la programmation à destination des enseignants du premier degré

The didactic works whose object of study concerns training practices have relied on the tools developed for the analysis of teaching practices by specifying them in the context of the training (Houdement & Kuzniak, 1996; Emprin, 2007; Sayac, 2012). In this work, we reuse and cross-reference these methodological tools in order to understand the practices of training in algorithms and programming for trainee school teachers. This case study allows us to better understand the challenges of this second year of initial training by highlighting the training knowledge, the strategies used as well as the epistemological postures called upon.

Improvement in Bioactivity Properties of Hydroxyapatite Coated Ti-6Al-4V ELI with Addition of Zirconium Oxide for Orthopaedic Implant
Authors: Ardhy Sanny , Gunawarman  , Affi Jon , Yetri Yuli
Published: February 2023

One of factor causing the failure of Ti-6Al-4V Extra Low Interstitial (ELI)-based material implants, does not have bioactive properties in the implantation process, thus not supporting the osseointegration process in the body. For this reason, coating with hydroxyapatite (HA) suspension is necessary. This research used the dip-coating method and added Zirconium Oxide (ZrO2) into nanosized commercial HA to be suspensions (17%wt and 20%wt) to strengthen the adhesion of the coating. The specimens were heated at 800, 900, and 950°C to densify the layers. Bioactivity increased along with the increasing calcium/phosphate (Ca/P) ratio of the HA layers in the test specimens. The specimens were immersed in Simulated Body Fluid (SBF), namely Hank’s Solution, for 1, 2, 3, and 4 weeks. ZrO2 added to the HA suspensions of Ti-6Al-4V ELI can increase the Ca/P ratio from 1.51 in the first immersion week to 1.62 in the fourth. The bioactivity level is also proven by the accumulation of calcium and phosphate on the surface of the coating. The Ca/P value close to the Ca/P ratio of HA of 1.67 is good for improving the osseointegration process in the body.

Objective:

This study aimed to reveal the antitumor effects of Chinese herbal formulae and the underlying mechanisms in treating colorectal cancer, with a focus on developing traditional Chinese medicine (TCM) as a supplement and alternative therapeutic method for cancers.

Materials and Methods:

Human colon cancer SW480 cells were treated with three Chinese herbal formulae, Bu Zhong Yi Qi Decoction, Fuzi Lizhong Decoction, and Pulsatilla Decoction at different concentrations (50–600 μg/mL) for 24, 36, and 48 h, respectively. Cell viability was determined using the resazurin reduction assay, and cell survival rate was evaluated using a colony formation assay. After treatment with different concentrations (50–600 μg/mL) of these three formulae for 48 h, the effects of the Chinese herbal formulae on cell apoptosis were investigated using Hoechst/propidium iodide (PI) staining. The positive PI-stained cells were investigated using an EnSpire multilabel plate reader and the positive Hoechst-stained cells were observed under a fluorescence microscope for morphological changes.

Results:

Bu Zhong Yi Qi Decoction, Fuzi Lizhong Decoction, and Pulsatilla Decoction inhibited SW480 cell proliferation in a dose-and time-dependent manner and induced cell apoptosis.

Conclusion:

Chinese herbal formulae with a special prescription form of TCM with antitumor effects bring a new perspective in line with the principles of TCM in cancer treatment.

Published: February 2023

BACKGROUND:

In this study, we attempted to assess the change of perception of postgraduate students on objective structured clinical examination (OSCE) in burns and plastic surgery after first five OSCE.

METHODS:

A prevalidated feedback questionnaire was used to assess and score the perception of postgraduate students on OSCE in burns and plastic surgery. The opinion of postgraduate students on the feedback questionnaire after first and fifth assessment tests based on OSCE was analyzed. The results were compiled on a data sheet and analyzed using Microsoft Excel and plotted as graphical interpretation. The statistical analysis was done using MedCalc software.

RESULTS:

The results of the study showed that there is a positive change in perception of students in favor of monthly assessment based on OSCE in burns and plastic surgery after fifth assessment. The mean students’ favorable perception score after the first assessment with was 30.2 ± 2.828 (mean ± standard deviation [SD]) and after fifth assessment, 43 ± 2.828 (mean SD) with Student's testt= 10.119 andP< 0.0001 which is highly significant statistically in favor of OSCE after fifth assessment.

CONCLUSIONS:

We observed in our study that the monthly assessment based on OSCE is well accepted by the students of our subspecialty after few assessments; however, further studies are required to augment the evidence.

Published: February 2023

BACKGROUND:

Health-care workers are exposed to complex types of health and safety hazards. A high percentage of hospital staff in Iran are women, who in addition to heavy and stressful hospital work, also carry the burden of the family roles. It is in these circumstances that creating a supportive environment for women is of particular importance. Accordingly, this study is designed to determine the characteristics of a mental supporting work environment in the workplace from the perspective of female hospital staff.

MATERIALS AND METHODS:

This study was performed by a qualitative method and content analysis approach. Sampling was purposive and 26 women working in different wards of this hospital were included in the study. In this study, women with maximum diversity in terms of age, work experience, and employment ward were selected. The main method of data collection in this study was a semi-structured interview. Interview texts were extracted and divided into meaningful units. To validate and confirm the results plus accuracy of the research, the criterion of data validity or data credibility, admissibility, data accuracy, verifiability, reliability, and transferability were used.

RESULTS:

Through the data analysis, 58 primary concepts with the same features were classified into 10 subcategories. Then, based on common features at a more abstract level, they were converted into four main categories including job stressors, women's stress management, providing women's psychological-job satisfaction, and women's work-life balance.

CONCLUSION:

Creating supportive work environments for women, especially those operating in workplaces such as hospitals, which brings a lot of work pressure and workload for them, can be an important policy for organizations and hospital work environments.

Background:

In the recent years, there has been a rapid increase in the use of robot assisted neck dissection (RAND) as an alternative method for conventional neck dissection. Several recent reports have emphasized upon the feasibility and effectiveness of this technique. However, substantial technical and technological innovation is still essential in spite of the availability of multiple approaches for RAND.

Materials and Methods:

The present study describes a novel technique, i.e., Robotic Infraclavicular Approach for Minimally Invasive Neck Dissection (RIA MIND) used in head and neck cancers with the help of Intuitive da Vinci Xi Surgical System.

Results:

After RIA MIND procedure, the patient was discharged on the third post operative day. Also, the total wound size was less than 3.5 cm which enhanced the patient recovery time and required minimal post operative care. The patient was further reviewed 10 days after the procedure for the removal of sutures.

Conclusion:

RIA MIND technique was effective and safe for performing neck dissection for oral, head and neck cancers. However, additional detailed studies will be required for establishing this technique.
Developing Framework Toward One Health Approach
Authors: Kapoor Suraj
Published: February 2023

Against a constant background of recognized infections, epidemics of new and old infectious diseases periodically emerge, greatly magnifying the global burden of emerging and re-emerging diseases. The emergence/re-emergence of these diseases is related to multifaceted factors, such as viral recombination and mutation, leading to more infectious and adaptive strains, industrialization and urbanization, and human activities such as deforestation creating a more permissive environment for vector-host interaction. A better knowledge of the causes and consequences of certain human activities, lifestyles, and behaviors in ecosystems is crucial for a rigorous interpretation of disease dynamics and to drive public policies. This article highlights the factors associated with emergence and re-emergence and in turn the importance and implementation of the One Health approach. Health-care professionals can prevent and control antimicrobial resistance by prescribing and dispensing antibiotics as per the laid down guidelines and indications. Sentinel surveillance at the point of entry should be strengthened. Successful One Health approaches require intersectoral coordination, with a team approach despite functioning in different sectors or domains. It is proposed that government and policy-makers should take scientific decisions about the creation of epidemiological surveillance centers at the district level on the concept of One Health. It should have facilities and infrastructure for ecosystem surveillance, namely air, water, soil, flora, and fauna, monitoring as well as investigation of the outbreak. Equally important is to empower the community and family members about the One Health concept and the matters concerned.
Topical Ivermectin in Ophthalmomyiasis
Authors: Dasari Gayatri
Published: February 2023

Ocular myiasis is a rare condition affecting orbital and ocular tissues infected by fly larvae of the order Diptera. This clinical case report highlights the importance and requirement of topical ivermectin eye drops for treating external ophthalmomyiasis. A 55-year-old female patient presented to the hospital who had a history of worms in her right eye in the last 6 months and was diagnosed with right eye external ocular myiasis. Mechanical removal of worms done under topical anesthesia and treated with oral tablet ivermectin 12 mg stat, ivermectin topical drops prepared by dissolving ivermectin 12 mg tablet in 10 ml distilled water and advised to instill four times a day, and oral tablet metronidazole 400 mg twice a day for 5 days. The patient effectively responded to the treatment with complete resolution and there was no recurrence. The treatment modality of ophthalmomyiasis depends on the clinical presentation and severity of tissue destruction and is planned on an individual patient basis. Mechanical debridement of worms under topical anesthesia with adjuvant oral ivermectin is recommended. Topical ivermectin eye drops can be used to kill the worms in places where they cannot be manually reached. Further studies are needed to study the efficacy of topical ivermectin.

Authors: Lock Jing Zhan , Khoo Zi Xean , Pek Jen Heng
Published: February 2023

Introduction:

Paediatric patients admitted to the inpatient units from the emergency department (ED) are increasing, but the mean length of stay has fallen significantly. We aimed to determine the reasons behind paediatric one-day admissions in Singapore and to assess their necessity.

Methods:

A retrospective study involving paediatric patients who were admitted from a general ED of an adult tertiary hospital to a paediatric tertiary hospital between 1 August 2018 and 30 April 2020. One-day admission was defined as an inpatient stay of less than 24 h from the time of admission to discharge. An unnecessary admission was defined as one with no diagnostic test ordered, intravenous medication administered, therapeutic procedure performed or specialty review made in the inpatient unit. Data were captured in a standardised form and analysed.

Results:

There were 13,944 paediatric attendances — 1,160 (8.3%) paediatric patients were admitted. Among these, 481 (41.4%) were one-day admissions. Upper respiratory tract infection (62, 12.9%), gastroenteritis (60, 12.5%) and head injury (52, 10.8%) were the three most common conditions. The three most common reasons for ED admissions were inpatient treatment (203, 42.2%), inpatient monitoring (185, 38.5%) and inpatient diagnostic investigations (32, 12.3%). Ninety-six (20.0%) one-day admissions were unnecessary.

Conclusion:

Paediatric one-day admissions present an opportunity to develop and implement interventions targeted at the healthcare system, the ED, the paediatric patient and their caregiver, in order to safely slow down and perhaps reverse the trend of increased hospital admissions.
