RELIGIOUS HYBRIDITY: THE RESPONSE OF MUSLIM YOUTH TO TERAS DAKWAH COMMUNITY
Authors: Lubis Muhammad Abdi
Published: April 2024

Religious hybridity warrants complex study due to its profound impact in engaging young Muslims with dynamic religious perspectives. Teras Da'wah in Yogyakarta has become a notable contemporary religious community, merging cultural and religious elements in its da'wah practices. This research delves into the hybridization process within the Teras Dakwah community, aiming to bolster the enthusiasm of young Muslims. Employing ethnographic and netnographic approaches, the study investigates the specific type of hybridization that Teras Dakwah utilizes to captivate worshippers from diverse backgrounds. The findings in this research show that the hybridization carried out by the Yogyakarta Teras Dakwah community combines religious and cultural elements in the process of preaching. A hybrid identity can also be seen in the ustaz, which gives lectures from various groups. Additionally, a hybrid identity is evident among the ustaz who deliver lectures from multiple perspectives. Notably, the Teras Dakwah's 'Fun Koran' program is particularly popular among millennials, as it adeptly addresses, understands, and incorporates the turmoil and diverse inputs from congregants. This research suggests a significant shift in the da'wah activities of young Muslims in contemporary times, moving from traditional to more hybrid methods.

Published: April 2024

This study aims to reveal the agent-structure relationship that occurs from the phenomenon of sacred grave pilgrimage in Dewi Sekardadu, Sidoarjo through the structuration theory by Anthony Giddens’s perspective as well as ritual communication studies. The type of this research is qualitative with ethnographic methods. This research uses a multi-site ethnographic method, namely by comparing historical facts at all Dewi Sekardadu’s sacred graves spread across four cities involving Sidoarjo, Gresik, Lamongan and Banyuwangi. The key informants were door-keepers, grave caretakers, community leaders, pilgrims and businessmen. The research data was collected by direct observation and participant observation, in-depth interviews and documentations. Then obtained data was analyzed using structuration theory and ritual communication studies. The result of this research had theoretical implications that support and reject Gidden’s sight. First, the proficient agents in Kepetingan have succeeded in changing the stigma of Kepetingan from a criminal area to a religious area through the development of folklore and ritual communication practices. Second, Giddens does not assume any clustering of agents of society for instance the caretaker cluster which has dominance on national scale but not in society, because the appointment process is considered less sacred. Third, Nyadran community structure occurred among indigenous fisherman from Bluru Kidul and Balongdowo which created to the grave pilgrims community structure in Kepetingan which was inhabited by urban fisherman from Gresik dan Lamongan regency.

Published: April 2024

The use of humor in Islamic da'wah can effectively approach the millennial generation more engagingly and entertainingly. This study aims to identify factors that need to be considered when using humor in the context of da'wah, especially when dealing with millennials with different characteristics and communication preferences. This study uses a library research method to develop a strong and comprehensive theoretical foundation related to the topic of study. The study's findings show that the application of humor in Islamic da'wah among the millennial generation requires a balanced approach between creativity, ethics, and a deep understanding of the characteristics of the millennial generation, which in turn affects the effectiveness of da'wah. A better understanding of millennials' communication preferences and values can enrich the use of humor to create emotional connections and effectively convey religious messages while ensuring that the messages remain consistent with the values of true Islamic teachings. This study implies that in the face of technological advancements and the social media landscape, humor can be an effective tool for fostering emotional connections with millennial audiences and effectively conveying religious messages, provided that its use is directed toward the positive goals of enriching religious understanding, strengthening communication, and ensuring consistency with Islamic values that are rahmatān lil alamin.
Constitutive Flt3 signaling impacts conventional dendritic cell function.
Authors: Mintern Justine , Wilson Kayla , Villadangos Jose
Published: April 2024

The development of dendritic cells (DCs) depends on signaling via
FMS-like tyrosine kinase 3 (Flt3) receptor. How Flt3 signaling impacts
terminally differentiated DC function is unknown. This is important
given the increasing interest in exploiting Flt3 for vaccination and
tumor immunotherapy. Here, we examined DCs in mice harboring
constitutively activated Flt3 (Flt3-ITD). Flt3ITD/ITD mice possessed
expanded splenic DC subsets including plasmacytoid DC, conventional DC
(cDC)1, cDC2, double positive (DP) cDC1 (CD11c+ CD8+ CD11b- CD103+
CD86+), noncanonical (NC) cDC1 (CD11c+ CD8+ CD11b- CD103- CD86-) and
single positive (SP) cDC1 (CD11c+ CD8+ CD11b- CD103- CD86+). Outcomes of
constitutive Flt3 signaling differed depending on the cDC subset
examined. In comparison to wild type (WT) DCs, all Flt3ITD/ITD cDCs
displayed an altered surface phenotype with changes in costimulatory
molecules, major histocompatibility complex class I (MHC I) and II (MHC
II). Cytokine secretion patterns, antigen uptake, antigen proteolysis
and antigen presenting function differed between WT and Flt3ITD/ITD
subsets, particularly cDC2. In summary, Flt3 signaling impacts the
function of terminally differentiated cDCs with important consequences
for antigen presentation.

Authors: Sarvode Supriya , Sacta Maria A. , Kehasse Amanuel , Mothi Suraj Sarvode , Shah Bhavesh , Sobota Amy
Published: April 2024

Background: Hydroxyurea remains underutilized in the pediatric
sickle cell population despite its well-known efficacy in decreasing
sickle cell complications and hospitalizations. Access to refills and
liquid formulation remains a critical barrier to adherence to
hydroxyurea regimens. This study was undertaken to determine the
clinical impact of home-delivering compounded liquid hydroxyurea (LHU)
to pediatric patients with sickle cell disease.
Procedure/Methods: A retrospective cohort study was conducted
using electronic health records and pharmacy databases. Pediatric
patients younger than 21 years of hydroxyurea initiation from March 2016
to July 2020 who received compounded LHU from Boston Medical Center
Pharmacy were included. The primary outcomes of the study were drug
adherence (assessed by evaluating the proportion of days covered), rates
of acute care utilization, laboratory values, and growth metrics before
and after enrolling in the LHU delivery program. Results: The
final cohort included 41 patients. Significant increases in hemoglobin
0.34 g/dl (95% CI: 0.04-0.63, p=0.02) and mean corpuscular volume 3.2
FI (95% CI: 0.92-5.4, p=0.007) occurred. Hospitalizations decreased by
51.3% (p=0.01), and acute chest syndrome episodes decreased by 86.4%
(p=0.02) post-initiation of the LHU delivery program. Drug adherence had
a median value of 0.95 one-year post-initiation of LHU.
Conclusions: Home delivery of compounded LHU improved drug
adherence, decreased hospitalizations, and improved laboratory outcomes
in pediatric patients with sickle cell disease by overcoming barriers to
access. Nationwide implementation of similar home delivery programs can
significantly improve outcomes among pediatric patients with sickle cell
disease.

Published: April 2024

Phenotypic plasticity is the ability of organisms to respond to
environmental changes. Understanding and leveraging crop phenotypic
plasticity is crucial for mitigating the threats caused by climate
change. Here, we assessed phenotypic plasticity in multi-environment
trials over 4 years, covering a wide geographical area, using 505 inbred
lines from a Brassica napus genetic diversity panel. The observed
phenotypic variation for seed oil content (SOC) was influenced by three
environmental indices (precipitation, diurnal temperature range, and
ultraviolet B) during the flowering or pod-filling stage alongside five
plasticity genes. Leveraging this information with climate records, we
developed a predictive model to estimate SOC for various planting dates
in seven major production regions, and validated the accuracy of our
predictions in new environments. With the quantified plasticity
conferred by genetic variation in the five plasticity genes, we
identified an optimal haplotype for each production region for
adaptability to future climate projections. This study offers valuable
insights and selection of materials to mitigate the adverse effects of
climate change on agriculture.
Atrial Flutter with Atrial Alternans in a Patient with Cardiac Amyloidosis
Authors: Z Tasneem Naqvi , Kurt Merve
Published: April 2024

Mechanical cardiac alternans is usually associated with left ventricular
dysfunction. Atrial alternans has been described on invasive assessment
of atrial action potentials, however cannot be detected clinically.
Herein we report a patient who had transthyretin type cardiac
amyloidosis with prior history of recurrent atrial fibrillation
requiring ablations as well as ablation for atrial flutter and a recent
history of cardioversion for atrial flutter. The patient presented with
diastolic heart failure and recurrent atrial flutter and was referred
for a TEE guided cardioversion. Mechanical left and right atrial
alternans was seen on Doppler interrogation of both atrial appendages
with velocities corresponding to the flutter P wave on the ultrasound
ECG monitor. The patient was successfully cardioverted with the TEE
probe in situ. Post cardioversion TEE showed resumption of normal albeit
reduced mechanical atrial function in the left atrium and preserved
right atrial function in tissue Doppler imaging. Our case demonstrates
the mechanical phenomenon of atrial alternans in both atria on TEE with
disappearance of atrial alternans during sinus rhythm suggesting rate
related atrial alternans likely related to atrial stiffness from amyloid
infiltration and as well as possibly scar formation from prior
ablations.
Evolution of parasite transmission dispersion
Authors: MacDonald Hannelore , Bonhoeffer Sebastian , Regoes Roland
Published: April 2024

An open question in epidemiology is why transmission is often
overdispersed, meaning that most new infections are driven by few
infected individuals. For example, around 10\% of
COVID-19 cases cause 80\% of new COVID-19 cases. This
overdispersion in pathogen transmission is likely driven by intrinsic
biological heterogeneity among hosts, i.e. variability in SARS-CoV-2
viral loads. However, host heterogeneity could also indirectly increase
transmission dispersion by driving pathogen adaptation. Specifically,
transmission variation among hosts could drive pathogen specialization
to highly-infectious hosts. Adaptation to rare, highly-infectious hosts
could amplify transmission dispersion by simultaneously decreasing
transmission from common, less-infectious hosts. This study considers
whether increased transmission dispersion can be, in part, an emergent
property of parasite adaptation to heterogeneous host populations. We
develop a mathematical model using a Price equation framework to address
this question that follows the epidemiological and evolutionary dynamics
of a general host-parasite system. The results predict that parasite
adaptation to heterogeneous host populations drives high transmission
dispersion early in epidemics. Further, parasite adaptation can maintain
increased transmission dispersion at endemic equilibria as long as
virulence differs between hosts in a heterogeneous population. More
broadly, this study provides a framework for predicting how parasite
adaptation determines transmission dispersion for emerging and
re-emerging infectious disease.

Published: April 2024

In this research, the radially increasing axisymmetric discharge of an
electrically conducting fluid across a surface is accurately evaluated
mathematically using the influence of Soret number. The surface is
extended at an exponential speed in a radial direction, which causes
flow trends. New similarity transformations are discussed in order to
transform the governing, transform nonlinear partial differential
equations into standard derivatives. The Successive Linearization Method
is used to perform mathematical analysis for flow performing. The
Chebyshev spectral technique is utilized to resolve the linear system in
order to provide accurate solutions that converge effectively to the
whole numerical solution. Comparisons with earlier research are
conducted to evaluate the validity of the results on the distribution of
velocity, temperature and concentration. Verify convergence and accuracy
of the solution, the impacts of a few fluid factors are identified and
explained.
The Effect of Seamount Subduction on the Formation of Holocene Marine Terraces: A Comparison of Kinematic and Mechanical Plate Subduction Models
Authors: Komori Junki , Ando Ryosuke , Miura Seiichi , Arai Ryuta
Published: April 2024

Marine terraces have long been a subject of paleoseismology to reveal
the rupture history of megathrust earthquakes. However, the mechanisms
underlying their formation, in relation to crustal deformation, have not
been adequately explained by kinematic models. A key challenge has been
that the uplifted shoreline resulting from a megathrust earthquake tends
to subside back to sea level during subsequent interseismic periods.
This study focuses on the remaining permanent vertical deformation
resulting from steady plate subduction and examines it quantitatively
using three plate subduction models. Specifically, we pay attention to
the effects of irregular geometries in the plate interface, such as
subducted seamounts. Besides a simplified model examination, this study
employs the plate geometry around the Sagami trough, central Japan, to
compare with surface deformation observation. The subduction models
employed are the kinematic subducting plate model, the
elastic/viscoelastic fault model, and the mechanical subducting plate
model (MSPM). The MSPM, introduced in this study, allows for more
realistic simulations of crustal displacements by imposing net zero
shear stress change on the plate boundary. Notably, the presence of a
subducted seamount exerts a significant influence on surface
deformation, resulting in a concentrated permanent uplift above it. The
simulation of earthquake sequence demonstrates that coseismic uplifts
can persist over time and contribute to the formation of marine
terraces. The results demonstrated that the geological observations of
coseismic and long-term deformations can be explained by the influence
of a subducted seamount, previously identified in seismic surveys.
Construction of Long-Term Seismic Catalog with Deep Learning: A Workflow for Localized Self-Attention RNN (LoSAR)
Authors: Zhou Yijian , Ding Hongyang , Ghosh Abhijit , Ge Zengxi
Published: April 2024

Characterizing fault behaviors prior to large earthquakes through
long-term seismicity is crucial for seismic hazard assessment, yet
constructing high-resolution catalogs over extended periods poses
significant challenges. This study introduces LoSAR, a novel deep
learning-driven workflow that enhances phase picking by Localizing a
Self-Attention Recurrent neural network with local data, addressing the
generalization problem common in data-driven approaches. We apply LoSAR
to two distinct regions that are both featured by recent large
earthquakes: (1) preseismic period of the Ridgecrest-Coso region
(2008-2019), and (2) pre-postseismic period of the East Anatolian Fault
Zone (EAFZ, 2020-2023/04). Through detailed comparisons, we demonstrate
that LoSAR offers slightly higher detection completeness than the QTM
matched filter catalog, while boosts an over 100 times faster processing
and a superior temporal stability, avoiding low-magnitude gaps during
background periods. Against PhaseNet and GaMMA, two established phase
picker and associator, LoSAR proves more scalable and generalizable,
achieving roughly 2.5 times more event detections in the EAFZ case,
along with a ~7 times higher phase association rate. By
leveraging the two enhanced catalogs and b-value analysis, we gain
insights into the preseismic fault behaviors: (1) The Ridgecrest faults
are characterized by sparse and distributed seismicity across a band of
~20 km, revealing multiple orthogonal preexisting
faults; coupled with a low b-value that signifies this area as a
persistent asperity; (2) The Erkenek-Pütürge segment of EAFZ exhibits
complex fault geometry that forms a persistent rupture barrier, which
consists of a hidden conjugate fault system that presents as a
~10-km wide fault zone.

Published: April 2024

The coupling between the magnetosphere and solar wind contributes to the
energy, momentum, and mass transfer between the systems. However,
geomagnetic pulsations facilitate the continuation of this process in
the magnetosphere and the production of discrete auroral arcs.
Therefore, remote-sensing the magnetospheric conditions. Data analytics
with machine learning (ML) gives insight into scalability, adaptability,
and feature extraction compared to traditional empirical models. The
availability of big data in the Svalbard network spanning 25years from
1996 motivated the current study. Hence, we present the forecasting of
auroral Pc5 pulsations from solar wind parameters using the ML
technique. In the training phase, there was a regression of 0.75 and
MSE=11.90 nT2. The relationship between Pc5 forecast and observations in
low and high geomagnetic activity and solar activity showed good
consistency with R=0.76 and MSE= 11.4 nT2. For instance, the model
adapted well to the St. Patrick geomagnetic storm of March 17th, 2015
despite uncertainties in the data. In addition, the model also adapted
well with stunning performance in all Svalbard observatories with HOP
leading with 6949 prediction events and NAL with the least. Thus, this
was consistent with previous studies in terms of Pc5 pulsations
latitudinal or L-shell dependence. Finally, validation with Kp and F10.7
indices presented excellent coherence between the models. Overall, The
ML studied the connection between solar wind and interplanetary magnetic
field properties to the ground magnetic field perturbations with good
correlation results. Hence, the model will be fit for use by the
magnetospheric community for space weather studies.
Understanding heterogeneous and anisotropic porous media based on geometric properties derived from three-dimensional images

Published: April 2024

Natural porous media is generally heterogeneous and anisotropic. The
structure of porous media plays a vital role and is often the source of
the heterogeneity and anisotropy. In physical processes such as fluid
flow in porous media, a small number of major features, here referred to
as wide channels, are responsible for the majority of the flow. The
thickness and orientation of these channels often determine the
permeability characteristics. Typically, the identification of such
major features is conducted through time-consuming and expensive
simulations. Here we propose a prompt approach based on geometric
properties derived from three-dimensional (3D) images. The size or
radius of the major features is obtained via distance maps, and their
orientations are determined by Principal Component Analysis.
Subsequently, we visualize these features with color and color
brightness according to their orientation and size, together with their
location and distribution in 3D space. The simultaneous visualization of
anisotropy (orientation) and heterogeneity (size) in one plot provides a
straightforward way to enhance our understanding of pore structure
characteristics. Besides, we propose a refined stereographic projection
method to statistically illustrate both heterogeneity and anisotropy.
Based on these insights, we further present a new way to compress the
model size in numerical simulation, therefore significantly reducing the
computational cost, while retaining its essential characteristics.

Published: April 2024

This study presents the development of a TKE-l parameterization of the
diffusion coefficients for the representation of turbulent diffusion in
neutral and stable conditions in large-scale atmospheric models. The
parameterization has been carefully designed to be completely tunable in
the sense that all adjustable parameters have been clearly identified
and their number minimized as much as possible to help the calibration
and to thoroughly assess the parametric sensitivity. We choose a mixing
length formulation that depends on both static stability and wind shear
to cover the different regimes of stable boundary layers. We follow a
heuristic approach for expressing the stability functions and turbulent
Prandlt number in order to guarantee the versatility of the scheme and
its applicability for planetary atmospheres composed of an ideal and
perfect gas such as that of Earth and Mars. Particular attention has
also been paid to the numerical stability at typical time steps used in
General Circulation Models. Test, parametric sensitivity assessment and
preliminary tuning are performed on single-column idealized simulations
of the weakly stable boundary layer. The robustness and versatility of
the scheme are also assessed through its implementation in the LMDZ
General Circulation Model and the Mars Planetary Climate Model and by
running simulations of the Antarctic and Martian nocturnal boundary
layers.

Published: April 2024

Fundamental processes in plasmas act to convert energies into different
forms, e.g., electromagnetic, kinetic and thermal. Direct derivation
from the Valsov-Maxwell equation yields sets of equations that describe
the temporal evolution of the magnetic, kinetic and internal energies in
either the monofluid or multifluid frameworks. In this work we focus on
the main terms that affect the changes in the kinetic energy. These are
pressure gradient-related terms and electromagnetic terms. The former
account for plasma acceleration or deceleration from a pressure
gradient, while the latter from an electric field. The overall balance
between these terms is fundamental to ensure the conservation of energy
and momentum. We use in-situ observations from the Magnetospheric
MultiScale (MMS) mission to study the relationship between these terms.
We perform a statistical analysis of those parameters in the context of
magnetic reconnection by focusing on small-scale Electron Diffusion
Regions and large-scale Flux Transfer Events. The analysis reveals a
correlation between the two terms in the monofluid force balance, and in
the ion force and energy balance. However, the expected relationship
cannot be verified from electron measurements. Generally, the pressure
gradient related terms are smaller than their electromagnetic
counterparts. We perform an error analysis to quantify the expected
underestimation of gradient values as a function of the spacecraft
separation compared to the gradient scale. Our findings highlight that
MMS is capable of capturing energy and force balance for the ion fluid,
but that care should be taken for energy conversion terms based on
electron pressure gradients.
An Ensemble Modeling Framework for Propagating Solar Wind Conditions to Jupiter
Authors: Rutala Matthew J. , Jackman Caitriona M. , Owens Mathew J. , Tao Chihiro , Fogg Alexandra R. , Murray Sophie
Published: April 2024

The important question of how the solar wind influences Jupiter’s
magnetosphere is difficult to answer due to the lack of consistent
up-stream monitoring of the interplanetary medium (IPM) and the
large-scale dynamics internal to the magnetosphere. To compensate for
the relative lack of in-situ data, solar wind propagation models are
often used to estimate the ambient IPM conditions near Jupiter for
comparison to remote observations or in-situ measurements. A statistical
analysis of the timescales over which Jupiter’s magnetosphere reacts to
changes in the IPM would allow the solar wind interaction to be better
decoupled from internal dynamics; however, solar wind propagation from
near-Earth measurements out to Jupiter introduces uncertainties in both
the timing and magnitude of changes in the IPM which are themselves
difficult to assess. Here, we present an ensemble modeling framework for
the solar wind at Jupiter. A variety of existing solar wind models were
compared to in-situ measurements from near-Jupiter spacecraft spanning
diverse spacecraft-Sun-Earth alignments and phases of the solar cycle,
amounting to more than 23,000 hours over four decades. Typical errors in
prediction timing and magnitude, as well as conditions under which the
different input models performed better than average, were then
characterized as part of this framework. The resulting ensemble model
produces the most-probable near-Jupiter IPM conditions for times within
the tested epoch and provides the estimated variance in these
conditions, allowing for a statistical analysis of the relationship
between Jupiter’s magnetosphere and the solar wind. In addition to
remote sensing studies, the robust modeling of solar wind conditions
near Jupiter is crucial to ongoing and future in-situ studies
using Galileo, Juno, JUICE, and Europa Clipper
measurements; the compression or expansion of the magnetosphere is
crucial to interpreting in-situ measurements of Jupiter’s middle and
outer magnetosphere. Finally, we will discuss how the work presented
here can be extended towards more robust characterization of solar wind
parameters and time-dependent propagation of solar wind conditions at
other planetary magnetospheres.

Published: April 2024

Introduction. Cataract density is highly important factor when choosing a
surgical method and setting the parameters of a phacoemulsification device.
Diagnostic devices enable automated assessment of lens opacification degree.
Material and Methods. Study included 30 patients operated on for senile
cataracts at the Clinic of Eye Diseases of the University Clinical Center of
Vojvodina. After determining the preoperative best corrected visual acuity,
cataract density was assessed using the Pentacam Nucleus Staging scale of
the Scheimpflug imaging system, Pentacam AXL Wave (Oculus, Wetzlar,
Germany). The evaluation of the applied ultrasound energy during
phacoemulsification was quantified and expressed in the form of Cumulative
Dissipated Energy index of the Centurion Vision System (Alcon, Irvine, USA)
eye microsurgery device. The obtained results are expressed in the form of
mean values, and their connection is presented in the form of correlation.
Results. Statistically significant positive correlation was found between
the cataract density expressed with use of the Pentacam Nucleus Staging
scale and the applied ultrasound energy during surgery, expressed in the
form of Cumulative Dissipated Energy index (r=0.37, p=0.04). No
statistically significant correlation was found between preoperative best
corrected visual acuity and cataract density expressed with the Pentacam
Nucleus Staging scale (p>0.05) or between preoperative best corrected visual
acuity and Cumulative Dissipated Energy index (p>0.05). Conclusion. The
obtained data indicate a positive correlation (r=0.37, p=0.04) between the
degree of lens opacification assessed by Pentacam Nucleus Staging scale and
the required ultrasound energy applied during phacoemulsification expressed
as Cumulative Dissipated Energy index.

seasonal distribution, and sociodemographic characteristics of patients
admitted to the Department of Child and Adolescent Psychiatry. Material and
Methods. The study was conducted at the Psychiatry Clinic of the Department
of Child and Adolescent Psychiatry at the University Clinical Center of
Vojvodina in the period from March 6, 2017 to March 5, 2021. The sample
comprised 1114 inpatients and individuals undergoing partial
hospitalizations, diagnosed with mental disorders classified according to
the International Classification of Diseases. Participants were categorized
into two groups: one treated before the onset of the pandemic (March
2017-March 2020) and another treated during the pandemic (March 2020-March
2021). Statistical analysis was performed on the collected data, with the
results presented in tables and graphs. Results. During the pandemic, an
overall reduction in admissions (-32.34%) was observed, accompanied by a
noticeable decrease in admissions during the spring compared to the
pre-coronavirus period (p=0.011). The most prevalent diagnoses were F9 and
F4, respectively (p<0.01). A higher number of hospitalizations were noted in
middle adolescence (p<0.001), among females (p=0.006) and those residing in
urban areas (p=0.009). Conclusion. The coronavirus pandemic led to
alternations in the functioning and dynamics on Department of Child and
Adolescent Psychiatry. The sociodemographic characteristics of the youth
changed during the pandemic.

Published: April 2024

Introduction. Pain is the most common cause of complaints in hospitalized
pediatric patients. Pain continues to be underestimated and undertreated in
childhood. The European Society of Pediatric Anesthetists has published
guidelines for pain management in children. Pain assessment. Pain assessment
is very important in the treatment of pain in children. Basic pain
management. Administration of basic analgesics is crucial for pain
management. Paracetamol and non-steroidal anti-inflammatory drugs.
Generally, basic or simple analgesia includes the use of paracetamol and
non-steroidal anti-inflammatory drugs. Systemic opioids. Opioids are
reserved for early postoperative and intraoperative use when adequate
monitoring and specially trained personnel are available around the clock.
Regional anesthesia and local anesthetics. Regional anesthesia in children
has been increasingly used in recent decades, particularly against the
background of multimodal analgesia. Conclusion. Basic analgesics are
crucial, and opioids are added only when needed. Regional anesthesia and
local anesthetics play a superior role in pain management compared to
systemic analgesics in such cases in pediatric patients.

Introduction. Leiomyoma is a mesenchymal benign tumor that seldom manifests
in the kidney. Typically, these tumors are small, asymptomatic, and often
detected accidentally. Differentiating leiomyomas radiologically from other
renal neoplasms, particularly renal cell carcinomas, poses a considerable
challenge before surgical intervention. Moreover, the conclusive diagnosis
of leiomyomas can only be established through histopathological and
immunohistochemical evaluation following surgical intervention. Case Report.
We present a case of a 44-year-old woman who was diagnosed with right kidney
leiomyoma accidentally during a computed tomography examination following
exploratory curettage by a gynecologist. An enhanced computed tomography
scan revealed a 10 mm tumor located on the upper pole of the right kidney,
extending beyond its boundaries. The imaging differential diagnosis was
renal cell carcinoma of the right kidney. A laparoscopic partial nephrectomy
was performed. Macroscopically, the tumor appeared subcapsular,
well-defined, with a firm consistency and a tan-white whorled cut surface.
The histological characteristics and the supporting immunohistochemical
profile confirmed the diagnosis of renal leiomyoma. The postoperative course
was uneventful, and the patient was discharged on the 3rd postoperative day.
Conclusion. Leiomyomas are rare kidney tumors. A conclusive diagnosis is
established through histopathological findings. The pre-operative
differentiation of leiomyomas radiologically from other renal neoplasms,
particularly renal cell carcinomas, poses a considerable challenge in
radiological assessment.
Safe Farming: Ultra-Fine Sparkling Water can Reduce Insect Pests and Increase Melon Yield and Quality
Authors: CY Ching
Published: April 2024

Melon pest control relies on over-application of pesticides. Reducing pesticide spraying has become a global issue for environmental sustainability and human health. Therefore, it is important to develop a new growing system that is sustainable and environmentally friendly. This study found that melon seedlings irrigated with ultrafine water containing H2 and O2 (UFW) produced more root hairs, increased branch height, and produced more flowers than the control irrigated with reverse osmosis (RO) water. Surprisingly, we also found that UFW irrigation significantly reduced aphid infestations in melons. Based on cryoscanning electron microscopy (cryo-SEM) observations, UFW treatment enhanced trichome development and prevented aphid infestation. To investigate whether it was H2 or O2 to prevent insect damage, we prepared UF enriched water with H2 (UF+H2 ) and O2 (UF+O2 ) alone and irrigated the melons. Cryo-SEM results show that UF+H2 and UF+O2 can increase the density of trichomes in melon leaves and petioles. RT-qPCR showed that UF+H2 significantly increased the gene expression level of the trichome-related gene GLABRA2 (GL2). We grow muskmelons in plastic greenhouses and use ultrafine water-rich hydrogen (UF+H2 ) and oxygen (UF+O2 ). The SPAD value, photosynthetic parameters, root weight, fruit weight, and fruit sweetness are all better than those without ultrafine water irrigation of comparison. UFW significantly promoted the development of trichomes, enhanced insect resistance, and improved fruit traits. The system therefore provides useful water management for pest control and sustainable agricultural production.
Prevalence of Tinea capitis in Schoolchildren in Three Villages of Woleu-Ntem Province Haut Ntem Department, Gabon
Authors: OG Sekangue
Published: April 2024

Introduction: Tinea capitis is a benign alopecising fungal infection mainly affecting schoolchildren with a tendency to spontaneous healing at puberty, and caused by dermatophytes. Objective: to determine the prevalence of Tinea capitis in schoolchildren in the Haut Ntem department. Materials and Methods: This was a descriptive cross-sectional study conducted from November 11, 2021 to April 7, 2022 in 3 villages in the Haut Ntem department. The ringworm lesions were taken from schoolchildren head using a scalpel and collected in a sterile Petri dish. Each sample was examined directly and cultured on Sabouraud Chloramphenicol Actidione medium. Tinea capitis was diagnosed if either direct examination or culture was positive. Results: Among the 128 children, included, median age was 9 years, Tinea capitis with small plaques (66.4%) were more frequent than those with large plaques (33.6%). The frequency of Tinea capitis was higher on direct examination (23.6%) than on culture (9.4%). The age group most affected by both direct examination and culture was [6-9 years] (p=0.27). After culture, Tinea capitis of the scalp was more frequent in Gabon-Ville (41.7%); whereas its frequency (25.0%) was similar in Akok and Gabon-Ville on direct examination. Endothrix parasitism was significantly more frequent (p<0.0001). Tinea capitis was mainly due to the Trichophyton genus (100%, p<0.0001). Conclusion: Tinea capitis are a public health problem in rural Gabon. They are dominated by small-plate ringworm caused by fungi of the Trichophyton genus.
Prevalence of Increased Screen usage during Nationwide Lockdown for Containing COVID-19 and its Ocular Implications
Authors: J Sahu
Published: April 2024

Purpose: We aim to assess the prevalence of increased screen usage among Indians during lockdown due to COVID-19 pandemic and its associations with self-reported dry eye symptoms. Method: This cross-sectional study was conducted in April 2020 during the total lockdown period for containment of COVID-19 virus. 382 healthy participants facing home confinement due to lockdown were enrolled. Symptoms of dry eye and amount of screen time were assessed by means of an online questionnaire. The questionnaire was freely accessible and participants were recruited by sharing the questionnaire, prepared on Google Docs, on various social networking platforms. The survey was open for responses for 3 weeks. All valid responses were tabulated and analysed using Microsoft Excel spread sheets and licensed SPSS version 26. Result: We found that about 86% of surveyed candidates reported an increase in time spent on smartphones and other video display gadgets during the lockdown. Higher prevalence rates for symptomatic dry eye were observed in individuals who reported increased daily exposure to smartphones during the lockdown as compared to those who did not (23.03% vs 9.61%; OR 2.914, 95% CI: 2.682-2.976; p<0.05). Longer daily smartphone use (>4 hours) was associated with a higher mean number of ocular symptoms (4-6 symptoms in 32.08% vs 26.06%), need of voluntary abstinence from screen (p<0.05) and the need of eye drops to feel better (p<0.05). Internal consistency was moderate (Cronbach's alpha = 0.674), indicating some variability in reporting. Conclusion: COVID-19 containing lockdown has seen society pivot from real world interactions to the online space. Recognising the collateral effects of the lockdown on screen usage and its implications on ocular health is imperative to alert the general public about such hazards.
