Análisis de ciclo de vida en aceites esenciales y productos agroindustriales: una revisión de aspectos metodológicos.
Authors: Mantilla Nicolás Andrés , Jaramillo Julián Ernesto , Villegas Juan David
Published: June 2023

Contextualización: el Análisis de Ciclo de Vida [ACV] constituye una herramienta útil para evaluar impactos potenciales ambientales de un producto. Dado el creciente interés en la mitigación del cambio climático y en la implementación de prácticas productivas sostenibles, resulta interesante estudiar el perfil ambiental de los productos de origen agrícola, con énfasis especial en los aceites esenciales, para identificar deficiencias en las tecnologías actuales y oportunidades de mejora.
Vacío de conocimiento: la literatura existente sobre líneas de producción de aceites esenciales es bastante limitada, pese a que el estudio de dichos procesos es bastante similar al de otros productos derivados de materia prima agrícola y de los cuales la bibliografía referente a su fabricación es más amplia.
Propósito: revisar los aspectos metodológicos abordados en investigaciones relacionadas con el análisis de ciclo de vida de materias primas agrícolas, haciendo énfasis especial en la producción de aceites esenciales. También se enfatizó en aquellos autores que utilizaron enfoques no convencionales y se describieron las razones que los motivaron a ello.
Metodología: Se buscaron y filtraron trabajos investigativos de los últimos 12 años en los que se analizó el ciclo de vida de productos agroindustriales. Los aspectos revisados incluyeron el alcance del análisis, las categorías de impacto, la unidad funcional, las fuentes de información, los métodos de asignación y las herramientas (software y base de datos) usadas.
Resultados y conclusiones: a partir de los aspectos mencionados anteriormente, fue posible identificar tendencias metodológicas como el uso del enfoque de cuna a la puerta, el software SimaPro, la base de datos Ecoinvent y los métodos de asignación másico y económico. Respecto al último método, se encontró que la asignación económica se acentúa más en el caso de los aceites esenciales, debido a las diferencias significativas que existen entre su masa y valor económico.
Analysis of Driving and Inhibiting Factors of Literacy Activities in MIN 4 Sukoharjo
Authors: Nitami Ayu
Published: June 2023

Literacy activities are important for students because they can improve critical thinking skills, creativity, and other thinking skills. The GLS program was established to help improve student literacy activities in schools. This study aims to determine the driving and inhibiting factors of literacy activities in MIN 4 Sukoharjo. This research uses a qualitative approach. The subjects in this study were teachers. In comparison, the informants in this study were the principal and students. Data is collected through observation, interview and documentation techniques using observation sheet instruments and interview guidelines. Data analysis techniques carried out include four stages, namely the stages of data collection, data reduction, data presentation, and conclusions. The study results show that the success of implementing literacy activities is influenced by supporting factors from schools, students, parents and the role of teachers as facilitators of literacy activities in schools. Inhibiting factors that affect the implementation of literacy activities come from students' lack of awareness to implement literacy activities, the availability of facilities in schools, the lack of teachers' ability to implement good and correct literacy activities, and the lack of cooperation between schools and parents

Published: June 2023

Objective This article aims to analyze correlations between
microvascular density (MVD) of nude mice as well as VEGF and
contrast-enhanced ultrasound (CEUS) parameters. Method Construct a model
with 60 ovarian cancer of nude mice. Via ultrasound contrast agent
injected intravenously.the enhancement features of tumors were observed
in real time and the time-intensity curve (TIC) of CEUS was also
obtained. By conducting quantitative analysis of Gamma-fit, we were able
to get the relative parameters. Utilizing CD34 and CD31 for counting,
the indices of MVD and VEGF level of “hotspot” area inside the tumors
were measured. Through the analysis of CEUS image characteristics of
ovarian cancer model in contrast with IHC indices, we discussed about
their correlations. We matched 10 nude mice granuloma models to find
differences between IHC quotas and CEUS parameters. Result The
differences in CEUS clearing patterns of nude mice with different growth
periods (30 days / 40 days) were considered statistically significant.
surface density and H-score of CD31, CD34 and VEGF were significantly
different between the transplanted tumor group and the granuloma group
in nude mice.Statistics in correlation between CEUS parameter indices
and IHC showed that the area under the curve (AUC)and average optical
density of CD31 are positively correlated，the arrival time (ATM) and
average optical density of VEGF are positively correlated. Conclusion
There are differences among the microvascular architectures of ovarian
cancer given different growth cycles. CEUS has shown its value during
the clearing phases. The microvascular architecture of ovarian cancer
and granuloma is obviously different. However, there are overlaps
between their CEUS performances, where there is no significant
statistical difference. The area under the curve (AUC) and time to
arrival (ATM) of the quantifiers were positively correlated with CD31
and VEGF, which is helpful for clinical applications in early diagnosis
and prognosis of ovarian cancer patient
Combating the Devastating Effects of Cotton Bollworm: Case of Uzbekistan
Authors: Shokirova Gavharhon , Juraev Zuhriddin
Published: June 2023

Bollworm poses a significant threat to cotton crops worldwide, including
in the Fergana province of Uzbekistan. This study aims to explore
innovative approaches to bollworm control and contribute to the global
understanding of integrated pest management strategies (IPM). Using an
extensive literature review and field observations, the study evaluates
the effectiveness of an integrated protection system in reducing
reliance on chemical inputs while increasing overall efficiency. The
results highlight the multigenerational life cycle of bollworm, its
impact on various crops, and the need for artificial biological control
methods and targeted insecticide applications. In addition, the study
highlights the need to adopt globally accepted IPM practices to ensure
sustainable pest management. The findings underscore the importance of
collaboration among researchers, farmers, policymakers, and industry
representatives in developing and implementing advanced control
measures. Through integrated approaches and the incorporation of
scientific advances, bollworm infestations can be contained while
safeguarding agricultural productivity and minimizing environmental
risks.
Real Effect or Bias? Best Practices for Evaluating the Robustness of Real-World Evidence through Quantitative Sensitivity Analysis for Unmeasured Confounding
Authors: Faries Douglas , Gao Chenyin , Zhang Xiang , Hazlett Chad , Stamey James , Yang Shu , Ding Peng , Shan Mingyang , Sheffield Kristin , Dreyer Nancy
Published: June 2023

The assumption of ‘no unmeasured confounders’ is a critical but
unverifiable assumption required for causal inference yet quantitative
sensitivity analyses to assess robustness of real-world evidence remains
underutilized. The lack of use is likely in part due to complexity of
implementation and often specific and restrictive data requirements
required for application of each method. With the advent of sensitivity
analyses methods that are broadly applicable in that they do not require
identification of a specific unmeasured confounder – along with
publicly available code for implementation – roadblocks toward broader
use are decreasing. To spur greater application, here we present a best
practice guidance to address the potential for unmeasured confounding at
both the design and analysis stages, including a set of framing
questions and an analytic toolbox for researchers. The questions at the
design stage guide the research through steps evaluating the potential
robustness of the design while encouraging gathering of additional data
to reduce uncertainty due to potential confounding. At the analysis
stage, the questions guide researchers to quantifying the robustness of
the observed result and providing researchers with a clearer indication
of the robustness of their conclusions. We demonstrate the application
of the guidance using simulated data based on a real-world fibromyalgia
study, applying multiple methods from our analytic toolbox for
illustration purposes.
Evolution of larval gregariousness is associated with host plant specialisation, but not host morphology, in Heliconiini butterflies
Authors: McLellan Callum , Montgomery Stephen
Published: June 2023

Insect herbivores, such as lepidopteran larvae, often have close
evolutionary relationships with their host plants, with which they may
be locked in an evolutionary arms race. Larval grouping behaviour may be
one behavioural adaptation that improves host plant feeding, but
aggregation also comes with costs, such as higher competition and
limited resource access. Here, we use the Heliconiini butterfly tribe to
explore the impact of host plant traits on the evolution of larval
gregariousness. Heliconiini almost exclusively utilise species from the
Passifloraceae as larval host plants. Passifloraceae display incredible
diversity of form, leaf shape and a range of anti-herbivore defences,
suggesting they are locked in an arms race with Heliconiini larvae. By
analysing larval social behaviour as both a binary (solitary or
gregarious) and categorical (increasing larval group size) trait, we
revisit the multiple origins of larval gregariousness across
Heliconiini. We investigate whether host habitat, leaf defences and leaf
size are important drivers of, or constraints on, larval gregariousness.
Whereas our data do not reveal links between larval gregariousness and
the host plant traits included in this study, we do find an interaction
between larval host specialisation and behaviour, revealing gregarious
larvae to be more likely to feed on a narrower range of host plant
species than solitary larvae. We also find evidence that this increased
specialisation typically precedes the evolutionary transition to
gregarious behaviour. The comparatively greater host specialisation of
gregarious larvae suggests that there are specific morphological and/or
ecological features of their host plants that favour this behaviour.
Spatial controls on eco-evolutionary processes in microbial communities
Authors: Ma Yinyin , Thakur Madhav , Johnson Davide
Published: June 2023

Microorganisms are the most biodiverse life forms on our planet, yet we
know little about the spatial processes underlying their ecology and
evolution. Here, we highlight the importance of two spatial processes
that act on individual cells - spatial intermixing of different
populations and mechanical cell shoving during growth - to improve our
understanding of microbial eco-evolutionary dynamics. Using an
individual-based model, we show that the coexistence of slow- and
fast-growing populations becomes highly constrained under two
conditions: when the slow- and fast-growing populations are highly
spatially intermixed and when the ability to shove other cells (both
conspecific and heterospecific) is weak. The potential for evolution
through plasmid-mediated horizontal gene transfer between slow- and
fast- growing populations also becomes restricted in the same scenario.
Our modeling highlights that ecological constraints can dampen
evolutionary opportunities within microbial communities due to variation
in spatial intermixing and mechanical shoving at the cellular scale.
Impact of Human Resource Management Reform in Public Hospital on Work Performance and Work-home Conflicts of Physicians in China
Authors: Liang Yuan , Han Liping , Wang Xiaoyu , Zhu Yimei , Wang Fang , Liang Jing , Ye Beizhu , Zhu Xi , Wang Zixin
Published: June 2023

Objectives To explore the impact of two measures of human
resource management reform, namely market-oriented employment
status(MOES) and equal pay for equal work(EPEW) with work performance
and work-family conflicts among physicians in public hospital in China.
Methods We conducted a national cross-sectional survey in 77
public hospitals across seven provinces in China between July 2014 and
April 2015, and 2785 physicians involved in this study. Work performance
included work engagement, career attrition and patient-centered care.
Work-family conflicts were composed of affecting care for family,
feeling guilty towards family and receiving complaints from family.
RESULTS Participants with MOES only account for 20.25%, those
with EPEW only account for 10.36% and those with MOES & EPEW account
for 4.35%. After adjusted for potential confounders, compared with
those who had no experience of human resource reform measures,
participants who had experiences of MOES & EPEW were more likely to
report positive work performance (pride in work: aOR = 4.35, 95% CI
:2.60–7.28; enjoyment of work: aOR = 4.46, 95% CI :2.71–7.35;
turnover intention: aOR = 0.40, 95% CI :0.25–0.65; early retirement:
aOR = 0.35, 95% CI: 0.21–0.58; exhaustion: aOR = 0.50, 95% CI
:0.31–0.81) and negative work-family conflicts (feeling guilty towards
family: aOR = 0.45, 95% CI :0.2810.73; receiving complaints from
family: aOR = 0.52, 95% CI :0.32–0.85). Analysis stratified by age
≥35y and <35y showed that the human resource reform measures
would have a higher effect on participants age ≥35y compared with those
age <35y. CONCLUSIONS The differences stratified by
age would reveal that salary system reform may need to be accelerated
further and employment system reform may need to be appropriately slowed
down, and accordingly, perfecting spiritual incentives measures would be
needed to overcome the decline of their effect over time in the future.
Adaptively exploring the feature space of flowsheets
Authors: Höller Johannes , Bubel Martin , Heese Raoul , Ludl Patrick , Schwartz Patrick , Schwientek Jan , Asprion Norbert , Wlotzka Martin , Bortz Michael
Published: June 2023

Simulation and optimization of chemical flowsheets rely on the solution
of a large number of non-linear equations. Finding such solutions can be
supported by constructing machine-learning based surrogates, relating
features and outputs by simple, explicit functions. In order to generate
training data for those surrogates computationally efficiently, schemes
to adaptively sample the feature space are mandatory. In this article,
we present a novel family of utility functions to favor an adaptive,
Bayesian exploration of the feature space in order to identify regions
that are convergent, fulfill customized inequality constraints and are
Pareto-optimal with respect to conflicting objectives. The benefit is
illustrated by small toy-examples as well as by industrially relevant
chemical flowsheets.
Trust and “being moved” as forms of engagement in situations of uncertainty
Authors: Cvejic Igor
Published: June 2023

The main aim of this paper is to put emphasis on the role of trust and the emotion of being moved in a situation of crisis. I do not intend to address the general role, or all roles, these emotions might have in a crisis situation. My focus is rather on the role of these emotions in we-formation, presupposing that mutual engagement between the actors is the crucial constituent through which first-person singular shifts to first-person plural. I rely on Bennet Helm?s argument on how trust can function as an invitation to delineate communal norms in the new circumstances of uncertainty. Accordingly, by being trusted by other(s), the addressee is entitled to the expected responsibility for a situation: (1) the addressee is entitled as a member of a group (of us who are responsible in the situation); (2) the addressee is exposed to pressure to respond to a situation with responsibility. In the second part, I adopt Cova?s and Deonna?s argument about the function of the emotion of being moved. I suggest that in such a situation ?being moved? expresses the readiness to reorganize one?s hierarchy of values in the light of new circumstances of mutual dependency. Taken together, trust and being moved portray the outline of mutual engagement between the actors in a crisis situation which aims to establish new communal norms and values.
Recent rainfall trends between 1990 and 2020: Contrasting characteristics between two climate zones in Burkina Faso (West Africa)
Authors: Yanogo Isidore Pawendkisgou , Yaméogo Joseph
Published: June 2023

The northern region (municipality of Samba) and the southwestern region
(municipality of Gaoua) are agricultural production areas, which are
however dependent on rain-fall. Therefore, knowledge of rainfall
characteristics is essential for good agricultural planning. Thus, the
objective of this study is to analyse the recent evolution of rainfall
between 1990 and 2020 in Burkina Faso. To this end, monthly rainfall data
were acquired from the National Meteorological Agency of Burkina Faso.
Statistical methods for detecting breaks in time series, standardised
rainfall indices, rainfall extremes and rainfall concentration were applied
to the data collected. The study shows that annual rainfall totals are
increasing between 1990 and 2020, but are marked by alternating wet and dry
periods. Moreover, precipitation is more concentrated in a few months
(July, August, September) in the northern region since the rainfall
concentration index (RCI) is ? 25% between 1990 and 2020, and precipitation
is more spread over several months (May, June, July, August, September,
October) in the southwestern region, since the RCI oscillates between
18.13% and 19.09%, except for the decade 2000-2010 when the RCI is 20.3%.
Therefore, the northern region is exposed to extreme precipitation (increase
in total wet days (precipitation ?1 mm) (JP), frequency of intense rainfall
(P95(day), intensity of rainy days (SDII (mm/day), maximum daily
precipitation (PXJA (mm)) more than the southwestern region (decrease in
frequency of intense rainfall, maximum daily precipitation). It is therefore
imperative for the national authorities to initiate resilience actions in
favour of farmers in the northern region.
Residential fencing and security aspect: The case of the new city of Ali Mendjeli in Constantine (Algeria)
Authors: Chekiel Abdelhafid , Benhassine-Touam Nassira
Published: June 2023

Our research article focuses on the security aspect in the living quarters of collective housing and aims to determine the main reasons for the residential fencing. Taking as a case study the new city of Ali Mendjeli, more specifically the 434 housing units in the neigh-bourhood unit No. 05, from a participatory social housing program. It is divided into two sections; the southern section, which consists of 242 housing units was the subject of our investigation. To fulfil the objectives of the research and get reliable results, we chose to work with a mixed-method research approach. Firstly, we used a quantitative method based on a questionnaire and then a qualitative method based on interviews and direct observation. The results of our survey revealed that the security aspect is a major concern for the inhabitants of the district, which leaded them to choose the residential fencing in an informal residentialisation process of the studied district, and by extrapolation of the surrounding districts. We also noted that the type of security sought as a top priority was for the dwellings, more than vehicles or persons, and the main obstacle to fencing work was financing. It seems to us that it would be right for the relevant authorities to take this aspect into consideration during urban upgrading processes but also in new housing programs so that this type of residential fencing integrates the upstream the study stage of this type of project.
Pole of inaccessibility as polygons for the development of a nature-oriented recreation system in Russia
Authors: Korolev Andrey
Published: June 2023

The concept of the pole of inaccessibility is defined as the point which is
situated as far as possible from the boundary objects, which are: operating
settlements, year-round roads or railways, the coastline of navigable water
bodies, as well as areas with ongoing economic activity with a change in
landscape type. The structure of non-populated areas, which can be
heterogeneous and have a focus and a periphery, has been studied. 4 levels
of uninhabited areas have been identified: local, regional,
national-continental and planetary. Uninhabited areas are the testing
ground for the development of nature-oriented recreational system (NRS). NRS
is a variant of the classical territorial recreational system (TRS) on
uninhabited territories, consisting of four subsystems: uninhabited areas,
tourists, regulatory authorities and service personnel. In most cases the
development of the NRS is carried out without its transformation into the
TRS, and it is necessary so that tourists can plan their routes logically
and safely, in the most interesting and attractive places.
Convergence of space and time through GIS
Authors: Valjarevic Aleksandar , Milosavljevic Sasa
Published: June 2023

Human's exploration of space has changed over time, depending on the
expansion of the limits of his knowledge. Space is infinite, but it is
limited by the possibility of human knowledge. The original man knew very
little about the space in which he lived - about its shape, size, content,
etc. Over time, the space began to take on the shapes that describe it.
Those forms are its dimensions, which increased as knowledge about space
in-creased. Knowledge spread more and more, from the Earth's surface to deep
into the cosmos. Time is known to everyone, but it is difficult to define
and understand. Science, philosophy, religion, art have different
definitions of time, but it can be defined as measuring the progress of
events. Space-time convergence explores the changing relationship between
space and time. Today it is used to interpret the impact of technological
progress on current world processes, especially globalization. The
development of computer technology and virtual reality techniques has led
to numerous changes in the representation of space. Since the initial
development of computer technology, human has tried to create a virtual
image of the world that he could experience with all his senses in the same
way as the image of the "real" world. GIS displays data in a visual, simple
and user-friendly form. The ability to transform spatial data into relevant
information represents its basic value and advantage.
Urban youth and protected areas - the south Banat region, Serbia
Authors: Jojic-Glavonjic Tamara , Denda Stefan
Published: June 2023

In December 2021 and January 2022, the inhabitants of the City of Pancevo
were surveyed using the random sampling method to find out to what extent
they are aware of the existence of protected areas in their vicinity and how
often they use them for outdoor trips and recreation. With the same aim, the
inhabitants of the City of Vrsac were also surveyed in mid-2022. This paper
presents the results concerning the youth of these two cities. The survey
covered 2.6% of the population between 15 and 24 years old in the City of
Pancevo and 2.2% of the population between 15 and 24 years old in the City
of Vrsac. Less than half of the respondents have the habit of going to
nature in their free time, and the main obstacles to this are the lack of
free time and money, as well as the lack of direct public transport
connections. In addition to the main research hypothesis, some other
hypotheses were tested related to the similarities or differences between
different groups of respondents in terms of the type of outdoor activities
they engage in. The results obtained are important for planning future
activities to preserve, improve and promote these valuable sites.
Green infrastructure, a thermal regulator for the arid city. Case study of the city of Bou-saada
Authors: Ouzir Malika
Published: June 2023

From a sustainable development perspective, becoming aware of the
preservation of green spaces and the creation of green infrastructure is a
great challenge for the Algerian arid city, especially in the arid
environment. Green infrastructure is multifunctional open space networks
aimed at sustainable resource management and environmental improvement. We
chose the city of Bou-saada as a case study to demonstrate the need for
green infrastructure. This city, with a semi-arid climate, presents a very
varied, complex and fragile historical, archeological and natural richness
subjected to strong anthropogenic pressures. The overall objective of this
research is to assess green infrastructure in the city of Bou-saada using a
qualitative barometer. This method uses several themes around the concept of
multifunctionality and thermal comfort, also using some subthemes to break
down the themes. Green infrastructure in the city of Bou-saada can withstand
the drought and heat emanating from this area, provide shade and reduce
heat, prevent soil degradation and desertification by stabilizing the soil
and mitigating wind-induced erosion. Through this research, we have also
looked at several issues such as safeguarding the natural heritage,
combating desertification, and siltation.
Involvement of α- and β-Adrenergic Receptors in Skeletal Muscle Blood Flow Changes During Hyper-/Hypocapnia in Anesthetized Rabbits
Authors: Koshika Kyotaro , Kaneko Rumi , Shionoya Mai , Shimizu Kotaro , Sendai Yuka , Matsuura Nobutaka , Akiike Yui , Ichinohe Tatsuya
Published: June 2023

Objective:

This study investigated the involvement of α1- and β2-adrenergic receptors in skeletal muscle blood flow changes during variations in ETCO2.

Methods:

Forty Japanese White rabbits anesthetized with isoflurane were randomly allocated to 1 of 5 groups: phentolamine, metaproterenol, phenylephrine, butoxamine, and atropine. Heart rate (HR), systolic blood pressure (SBP), common carotid artery blood flow (CCBF), masseter muscle tissue blood flow (MBF), and quadriceps muscle tissue blood flow (QBF) were recorded and analyzed at 3 periods: (1) baseline, (2) during hypercapnia (phentolamine and metaproterenol groups) or hypocapnia (phenylephrine, butoxamine, and atropine groups), and (3) during or after receiving vasoactive agents.

Results:

MBF and QBF decreased during hypercapnia. The decrease in MBF was smaller than that in QBF. SBP and CCBF increased, while HR decreased. Both MBF and QBF recovered to their baseline levels after phentolamine administration. MBF became greater than its baseline level, while QBF did not fully recover after metaproterenol administration. MBF and QBF increased during hypocapnia. The increase rate in MBF was larger than that in QBF. HR, SBP, and CCBF did not change. Both MBF and QBF decreased to ∼90% to 95% of their baseline levels after phenylephrine or butoxamine administration. Atropine showed no effects on MBF and QBF.

Conclusion:

These results suggest the skeletal muscle blood flow changes observed during hypercapnia and hypocapnia may mainly involve α1-adrenergic but not β2-adrenergic receptor activity.
Management of Anaphylaxis in Dental Practice
Authors: Goto Takashi
Published: June 2023

Anaphylaxis is a potentially fatal systemic complication that can occur as a side effect of dental treatment, oral and intravenous sedation, and general anesthesia. Although anaphylaxis rarely occurs during dental treatment, once it develops, the signs and symptoms progress rapidly and may lead to upper airway obstruction, respiratory distress, cardiovascular collapse, and cardiac arrest; thus, a prompt response is critical for saving lives. When anaphylaxis develops in a dental office, it should be diagnosed and managed immediately. Based on the clinical findings, emergency medical services should be activated and epinephrine administered intramuscularly without hesitation followed by transportation to a hospital facility for further care. It is very important to establish a definitive diagnosis of anaphylaxis after emergent care to identify the causative agent and perform subsequent dental treatment without triggering a recurrence. This review aims to explain the different issues and necessary considerations in managing anaphylaxis in the office-based dental setting based on established guidelines and practical guides for treating anaphylaxis.

Published: June 2023

We described a rare case of a splenic infarction associated with typhoid fever in a 26-year-old Bangladeshi man who returned from a vacation 10 days ago from his home country and presented to the emergency department with fever followed by left hypochondrial pain. Contrast-enhanced computed tomography of the abdomen showed multiple areas of splenic infarction. Salmonella typhi, which was sensitive to ceftriaxone, grew in the blood culture. The patient received intravenous ceftriaxone, analgesics, hydration, antiemetics, and other supportive care. He showed significant clinical improvement and was discharged. The patient was seen at the hospital two months after discharge, he was doing well and no splenic infarction could be detected by sonography.
Accessing disease information via smartphones: A senile macular degeneration investigation in over-65-year-old patients
Authors: Ay İbrahim Ethem , Şenol Yiğit , Er Aynur , Gobeka Hamidu Hamisi , Doğan Mustafa
Published: June 2023

Aim: To investigate how frequently over-65-year-old senile macular degeneration (SMD) patients use smartphones and the Internet for disease information, as well as to evaluate website readability and information quality.

Material and methods: There were 400 SMD patients who were followed up on at a retina clinic. SMD was defined as the presence of >5 hard drusen or >1 125 μm soft drusen in the macula, and scar or subretinal fluid compatible with SMD. Face-to-face interviews were used to gather demographic data, including age, gender, educational level, smartphone use, and whether patients researched SMD in Google, YouTube, or other websites. Two experienced ophthalmologists blindly evaluated 32 Google websites and 37 YouTube videos using Ateşman and Bezirci-Yilmaz readability formulas, as well as JAMA and DISCERN indexes.

Results: The average age of the patients was 75.0±6.6 years, and 37.3% owned a smartphone. Legally blind patients (40.5%) used smartphones less frequently for Internet searches (p<0.001). As educational level increased, patients became more active in searching diseases electronically. The JAMA score in texts was 0.8±0.4, while it was 0.7±0.6 in videos (p=0.654). The DISCERN score was 35.1±6.2 and 33.2±10.3 in texts and videos, respectively (p=0.347). Smartphone use decreased with age (OR=0.896, 95% CI: 0.859-0.934), but not with legal blindness (OR=0.756, 95% CI: 0.458-1.245).

Conclusion: Improved quality and reliability of internet websites and video information, more emphasis on informative audio recordings and videos for people with low vision, and easily readable Internet websites could all have a positive impact on patients' adherence to treatment.

Retroperitoneal cyst is very rare clinical condition having incidence 1:5750 to 1:250,000. Most of the retroperitoneal lesions are asymptomatic.

We are presenting a case of retroperitoneal cyst in a 65 years old female patient who presented with vague pressure symptoms. Exploratory laparotomy was performed. A large cystic right lumbar retroperitoneal mass displacing overstretched inferior vena cava, abdominal aorta and right psoas muscle seen intraoperative. Intact retroperitoneal cyst filled with its contents was removed.

Large lesion as in our study cause abdominal pain, mass effect on kidney and major vessel consistent. We excised cyst in totocyst preserving vital structure to prevent spillage and avoid further recurrence which is consistent with standard literature.

Retroperitoneal cysts are rare in incidence and asymptomatic. Due to silent nature and critical anatomy multidisciplinary approach is must for management of retroperitoneal cyst.
The association between insulin resistance, sleep disorders, and inflammation in obese children
Authors: Konuksever Dilek , Yücel Karakaya Sevinç Püren
Published: June 2023

Aim: Both obesity and sleep disorders cause chronic subclinical inflammation. Inflammation is a significant factor in triggering insulin resistance. This study aimed to analyze the association between sleep disorders, inflammation, and insulin resistance in obese/overweight children.

Material and methods: In this cross‑sectional study, 150 overweight/obese children were included. Sleep disorder was measured by using the Sleep Disturbance Scale for Children. The homeostasis model of assessment for insulin resistance (HOMA‑IR) was calculated according to fasting glucose and insulin results. Logistic regression models and Spearman Rank Correlation Coefficients were used to estimate associations between parameters.

Results: A statistically significant raising was found in insulin resistance and C-reactive protein levels in those with sleep disorders (p<0.05). However, no correlation was found between sleep disorders and the HOMA-IR, C-reactive protein, and neutrophil-to-lymphocyte ratio levels. On the other hand, HOMA-IR was weak positively correlated with neutrophil-to-lymphocyte ratio (r=0.222, p=0.006), and CRP (r=0.390, p<0.001).

Conclusion: Although we did not detect the association between sleep disorders and insulin resistance and C-reactive protein levels, we revealed that children with sleep disorders had higher insulin resistance and C-reactive protein levels than those without.

Pain in relation to the menstrual cycle is representative of Endometriosis. It has been reported that Endometriosis can be easily confounded with neoplasia. In the clinical practice of Gynecologic Oncology we find with relative frequency patients who are unknown carriers of endometriosis who present and are operated on because they resemble a picture of gynecological cancer, predominantly of the ovary. It has been reported that Endometriosis can be easily confounded with neoplasia. Endometriomas form part of the differential diagnosis alongside various ovarian cystic formations.

On the other hand, ovarian tumors are very common in women of reproductive age. Most are benign, but malignant ovarian tumors are a leading cause of cancer death in women.

In women with endometriosis, the risk of developing ovarian cancer has been estimated to be up to 50% higher than in the general population. The aim of our concise review was to establish the current state of knowledge regarding adnexal tumors associated with pelvic pain.

Introduction: Retro calcaneal bursitis is an inflammation of the bursa located between the posterior surface of the heel bone and the anterior surface of the Achilles tendon. This study was conducted to evaluate the clinical efficacy of endoscopic decompression and debridement in patients with retrocalcaneal bursitis who had not responded to conservative treatment. Our primary objective was to estimate the improvement in American Orthopaedic Foot and Ankle Society (AOFAS) score after surgery, and our secondary objectives were to estimate the average surgical duration and the incidence of post-operative complications.

Material and methods: This was a single-centre intervention study at a tertiary institution's level. Included in the study were all patients who were diagnosed with retrocalcaneal bursitis and who had failed a minimum 6-month trial of conservative treatment. 36 patients (36 heels) underwent endoscopic decompression.

Results: A prospective interventional cohort study was conducted on a total of 36 adult patients (18-70 years) with clinical and radiological findings suggestive of retrocalcaneal bursitis, duration of failed conservative treatment prior to surgery > 6 months, and refractoriness to other forms of non-operative treatment like steroid injections regardless of duration. There were no patients lost to follow-up. The mean duration of follow-up was 6 months [6 months to 2 years]. The average pre-operative AOFAS score was 56.42 6.8, ranging from 44 to 70. The difference between preoperative and postoperative AOFAS scores at 1 week, 2 weeks, 4 weeks, 3 months, and 6 months was statistically significant (p 0.0001).

Conclusion: In patients with retrocalcaneal bursitis, arthroscopic decompression is a safe, effective, and simple procedure. Within the first three months, the majority of study participants experienced pain relief and a significant improvement in function.

During the industrialization in Europe, rivers were straightened and designed to fit human activities, thus nowadays only a few natural river systems remain as reference conditions as well as guiding principles for river restoration projects. Therefore, the natural state of some river types is often described using historic records and maps. This study aims to analyze the key characteristics of a pristine proglacial river Katun in the Altai mountains and contribute to the knowledge about reference conditions. For this purpose, hydromorphological characteristics like slope, sinuosity and river width of the river Katun were analysed and summarized using different GIS techniques. Additionally, pebble counts were carried out to assess the changing sediment composition along the longitudinal continuum. Combined with River Habitat Surveys and a one-dimensional flow simulation using HEC-RAS it was possible to give a holistic overview of the dynamic fluvial system Katun in its upper, middle and lower reaches. The results confirmed the relationship between the river and its surrounding topography as they clearly show the lateral development of the Katun. As shown for the individual parameters (e.g., slope, width, depth, flow velocity, shear stress), they influence each other and are strongly dependent and characteristic for each river section. In the context of revitalisation of straightened and / or channelized river courses, it is important to focus on the processes of this interaction and provide suitable space for lateral expansion. The study can be seen as a recommendation on how to analyse hydromorphological characteristics of fluvial systems as well as to establish guiding principles in river restoration using remote sensing.

Flash floods have been blamed for significant losses and destruction all around the world are widely, including Vietnam, a developing nation that has been particularly hard hit by climate change. Therefore, flash flood hazards are essential for reducing flood risks. The topographic wetness index (TWI), altitude, slope, aspect, rainfall, land cover, normalized difference vegetation index (NDVI), distances to rivers and roads, and flow length were used in this study to create a spatial database of ten exploratory factors influencing the occurrence of flash floods in the Ngan Sau and Ngan Pho river basins (North-Central Vietnam). Subsequently, the analytic hierarchy process (AHP) was applied to calculate the weights of these influencing factors. The flood threat was then mapped using GIS techniques. The validation of the flash flood hazards involved 151 flood inventory sites in total. The findings demonstrate that (i) distance from rivers (0.14) and TWI (0.14) factors have the greatest influence on flash flooding, whereas distance from roads (0.06) and NDVI (0.06) factors were found to have the least influence; (ii) a good conformity of 84.8 percent between flood inventory sites and moderate to very high levels of flash flood hazard areas was also discovered; (iii) high and very high flood hazard levels covering areas of 275 and 621.1 km2 were mainly detected along and close to the main rivers and streams, respectively. These results demonstrated the effectiveness of GIS techniques, AHP, and Landsat-8 remote sensing data for flash flood hazard mapping.

Due to Tropical Storm Dianmu’s influence in the Lam Khan Chu watershed (LKCW) area, central Thailand saw its worst flood in 50 years from September 23 to September 28, 2021. The flooding lasted for 1-2 months. The objective of this research is to study flood susceptibility using logistic regression analysis in LCKW area. According to the study 11 floods occurred repeatedly between 2005 and 2021, in the southern of Bamnetnarong district and continued northeast to Chaturat district and Bueng Lahan swamp. These areas are the main waterways of the LKCW area, the Lam Khan Chu stream and the Huai Khlong Phai Ngam, for which the dominant flow patterns are braided streams. The main factors influencing flooding are geology, stream frequency, topographic wetness index, drainage density, soil, stream power index, land-use, elevation, mean annual precipitation, aspect, distance to road, distance to village, and distance to stream. The results of the logistic regression analysis shed light on these factors. All such variables were demonstrated by the β value coefficient. The area’s susceptibility to flooding was projected on a map, and it was discovered to have extremely high and high levels of susceptibility, encompassing regions up to 148.308 km2 (8.566%) and 247.421 km2 (14.291%), respectively, in the vicinity of the two main river sides of the watershed. As a result of this research the flood susceptibility map will be used as a guideline for future flood planning and monitoring.
