The goal of citizen/public engagement is to make develop trust between the government and the governed. However, evidence shows that citizens are losing trust on the government owing to misleading information. Thus, it has become imperative to investigate the underlying aim of government communication and the consequence of the approach adopted by the governments in engaging with their citizens. This paper sought to peripherally investigate the approach adopted by the Nigerian government between May 29th 2015, and May 29th 2023. Since the work of marketing the government is predominately domiciled within the official functions of the Minister of Information and Culture, this paper focuses on the speeches made by the then Minister. The study adopted agenda setting theory and propaganda model as the theoretical framework that guided the research. To attain the basic aim of this paper, qualitative content analysis was adopted by the researcher, which allows for the speeches made by the Minister within the timeframe being studied to be examined. This study found that most of the information and speeches made via interviews, press releases and press conferences for public consumption by the then Minister of on issues about security and economy were generally misleading. Thus, the study recommended that the government adopt a different but balanced approach, as its current strategy will likely cause general disillusionment amongst the citizenry. The balance must keep the citizens gainfully informed, even considering public safety, interest and the government's official secrets.

Kontribusi Pemikiran Tokoh Feminisme Islam
Authors: Tarhan Raden Muhammad , Syukur Syamzan , Rahmawati Rahmawati
Published: September 2024

Women in Islamic studies have reached a very important position. Many gender activists have discussed this topic, especially regarding gender equality. Several prominent feminist figures in the struggle for women's rights and gender equality include Qasim Amin, Amina Wadud Muhsin, and Fatimah Mernissi. Each of them has their own views about women. This article was prepared with the aim of presenting several opinions from these feminist figures and then extracting them. The writing of this article applies library research methods by collecting library materials sourced from books, journals and online articles. Based on this study, the view is obtained that Islamic feminist thought is very influential in reconstructing the interpretation of the position of women in Islamic law. This is a form of confirmation that interpretation is a subjective matter that is greatly influenced by the interpreter. Muslim feminist thought is actually relevant to the current context where men and women have equal positions.
Reduced contextual uncertainty facilitates learning what to attend to and what to ignore
Authors: Jungerius Chris , Perizonius Sophie , Slagter Heleen A.
Published: September 2024

Variability in the search environment has been shown to affect the capture of attention by salient distractors, as attentional capture is reduced when context variability is low. However, it remains unclear whether this reduction in capture is caused by contextual learning or other mechanisms, grounded in generic context-structure learning. We set out to test this by training participants (n = 200) over two sessions in a visual search task, conducted online, where they gained experience with a small subset of search displays, which significantly reduced capture of attention by colour singletons. In a third session, we then tested participants on a mix of familiar and novel search displays and examined whether this reduction in capture was specific to familiar displays, indicative of contextual cueing effects, or would generalise to novel displays. We found no capture by the singleton in either the familiar or novel condition. Instead, our findings suggested that reduced statistical volatility reduced capture by allowing the development of generic predictions about task-relevant locations and features of the display. These findings add to the current debate about the determinants of capture by salient distractors by showing that capture is also affected by generic task regularities and by the volatility of the learning environment.
Behavioural stochastic resonance across the lifespan
Authors: Di Ponzio Michele , Battaglini Luca , Bertamini Marco , Contemori Giulio
Published: September 2024

Stochastic resonance (SR) is the phenomenon wherein the introduction of a suitable level of noise enhances the detection of subthreshold signals in non linear systems. It manifests across various physical and biological systems, including the human brain. Psychophysical experiments have confirmed the behavioural impact of stochastic resonance on auditory, somatic, and visual perception. Aging renders the brain more susceptible to noise, possibly causing differences in the  SR phenomenon between young and elderly individuals. This study investigates the impact of noise on motion detection accuracy throughout the lifespan, with 214 participants ranging in age from 18 to 82. Our objective was to determine the optimal noise level to induce an SR-like response in both young and old populations. Consistent with existing literature, our findings reveal a diminishing advantage with age, indicating that the efficacy of noise addition progressively diminishes. Additionally, as individuals age, peak performance is achieved with lower levels of noise. This study provides the first insight into how SR changes across the lifespan of healthy adults and establishes a foundation for understanding the pathological alterations in perceptual processes associated with aging.

This paper for the 20th anniversary special issue of the Asian Journal of Agriculture and Development traces the evolution of my thinking on what to do about food price instability. Now that feeding the world is again front-page news, I am trying to figure out what pieces of my own thinking over the past half century might provide guidance on how to proceed. The world food system is under great stress as I write (early 2024), but this is probably a good time for some historical perspective as well as active engagement from people with knowledge of on-the-ground realities. I apologize in advance for the extensive listing of my own publications, but their story is my story.

Published: September 2024

In this study, it is aimed to examine the doctoral theses prepared in the field of social studies education in the USA and Turkey between the years 2018-2022 in terms of various categories. For this purpose, 113 doctoral theses accessed through ProQuest database and 121 doctoral dissertations accessed from YÖK Thesis Center database were analyzed by document analysis, one of the qualitative research methods. Theses examined in the study were analyzed in terms of 7 different categories such as the year, the university, research approach, research design, study group/sample, data collection tools and the subject. According to the findings obtained from the research, in both countries between 2018-2022, at least the thesis in the field of social studies education was prepared in 2020, while the year 2021 was the year in which the most theses were prepared in this sense. While “University of South Carolina” is the university where the most theses are produced in the USA, “Gazi University” comes first in Turkey. While more qualitative research approach, research designs and data collection tools were preferred in the USA, mixed research approach was mostly preferred in studies in Turkey. While researchers in the USA mostly work with teachers, the most studied sample/study group in Turkey is students. While doctoral theses in the field of social studies education in the USA were mostly prepared on teaching methods, due diligence, teacher self-efficacy, education policies and curriculum, theses in Turkey were generally prepared on teaching methods, value and skill acquisition. The results of the research show that the studies in the field of social studies education in Turkey tend to repeat, especially in terms of subject. In this sense, it is thought that this study can be a guide for researchers in Turkey to produce different and original researches.

Este trabalho propõe e testa uma metodologia bottom-up (BU) para projetar a variação anual do valor adicionado (VA) da agropecuária (produto interno bruto – PIB agropecuário) a preços do ano anterior, por meio de uma combinação de métodos econométricos com os prognósticos de safra feitos – com cerca de um ano de antecedência à divulgação da produção anual da produção – por órgãos especializados, como o Instituto Brasileiro de Geografia e Estatística (IBGE). Essa metodologia, além de permitir uma análise desagregada das tendências para o VA do setor, é capaz de produzir projeções consistentes com as previsões de produção do setor e de antecipar mudanças de tendências de uma maneira melhor que métodos puramente econométricos. Os resultados dos testes estatísticos implementados indicam que o método proposto possui maior acurácia nas previsões do PIB agropecuário do que o Boletim Focus de expectativas de mercado divulgado pelo Banco Central do Brasil (BCB), principalmente em anos de variações acentuadas no resultado do setor.

The Sun moves through the interstellar medium (ISM) at a velocity of ∼19 pc Myr−1, making the conditions outside the solar system vary with time over millions of years. Today’s solar system is protected from interstellar particles by the heliosphere, the bubble formed by the solar wind as the Sun moves through the ISM, which engulfs the planets. There is geological evidence from 60Fe that Earth was in direct contact with the ISM 2–3 and 5–7 million years ago (MYA). Recent work argues that the Sun encountered a massive cold cloud 2 MYA as part of the Local Ribbon of Cold Clouds that shrunk the heliosphere and exposed Earth to the ISM. Here, we consider the effects of the passage of the Sun through the edge of the Local Bubble occurring at

MYA assuming that the Sun encountered a cloud with a density of 900 cm−3. If we consider additional turbulent motion within the cloud due to shocks, the density encountered can be as low as 283 cm−3. Clouds of this density cover a small but nonzero (≲4.6%) fraction of the surface of the Local Bubble, making an encounter plausible. Using a state-of-the art magnetohydrodynamic model, we show that the heliosphere shrank to a scale smaller than Earth’s orbit, thereby exposing Earth to cold dense ISM, consistent with 60Fe evidence. The timing of the event matches perturbations observed in the paleoclimate record recovered from deep-sea sediments. The passage through the Local Bubble’s surface and contraction of the heliosphere therefore may have impacted the climate and biosphere significantly, suggesting a new driver of major events in Earth’s history.

The X-ray thermal isolated neutron star (XTINS) RX J0806.4–4123 shows interesting multiwavelength properties that seemingly deviate from those of similar neutron stars. An accurate determination of the spin frequency change over time can assist in interpreting RX J0806.4–4123's properties in comparison to those of other XTINSs and the wider pulsar population. From 2019 to 2023 we carried out a tailored X-ray timing campaign of RX J0806.4–4123 with the NICER instrument. We used statistical properties of the Fourier coefficients and the Z

Solar flare prediction studies have been recently conducted with the use of Space-Weather MDI (Michelson Doppler Imager on board Solar and Heliospheric Observatory) Active Region Patches (SMARPs) and Space-Weather HMI (Helioseismic and Magnetic Imager on board Solar Dynamics Observatory) Active Region Patches (SHARPs), which are two currently available data products containing magnetic field characteristics of solar active regions (ARs). The present work is an effort to combine them into one data product, and perform some initial statistical analyses in order to further expand their application in space-weather forecasting. The combined data are derived by filtering, rescaling, and merging the SMARP and SHARP parameters, which can then be spatially reduced to create uniform multivariate time series. The resulting combined MDI–HMI data set currently spans the period between 1996 April 4 and 2022 December 13, and may be extended to a more recent date. This provides an opportunity to correlate and compare it with other space-weather time series, such as the daily solar flare index or the statistical properties of the soft X-ray flux measured by the Geostationary Operational Environmental Satellites. Time-lagged cross correlation indicates that a relationship may exist, where some magnetic field properties of ARs lead the flare index in time. Applying the rolling-window technique makes it possible to see how this leader–follower dynamic varies with time. Preliminary results indicate that areas of high correlation generally correspond to increased flare activity during the peak solar cycle.

We test whether Lyα emitters (LAEs) and Lyman-break galaxies (LBGs) can be good tracers of high-z large-scale structures, using the Horizon Run 5 cosmological hydrodynamical simulation. We identify LAEs using the Lyα emission line luminosity and its equivalent width, and LBGs using the broadband magnitudes at z ∼ 2.4, 3.1, and 4.5. We first compare the spatial distributions of LAEs, LBGs, all galaxies, and dark matter around the filamentary structures defined by dark matter. The comparison shows that both LAEs and LBGs are more concentrated toward the dark matter filaments than dark matter. We also find an empirical fitting formula for the vertical density profile of filaments as a binomial power-law relation of the distance to the filaments. We then compare the spatial distributions of the samples around the filaments defined by themselves. LAEs and LBGs are again more concentrated toward their filaments than dark matter. We also find the overall consistency between filamentary structures defined by LAEs, LBGs, and dark matter, with the median spatial offsets that are smaller than the mean separation of the sample. These results support the idea that the LAEs and LBGs could be good tracers of large-scale structures of dark matter at high redshifts.
Scrotoliths in the testicular tunica vaginalis in an elderly male cadaver: clinical implications
Authors: Borthakur Dibakar , Dada Rima , Kumar Rajesh , Jacob Tony George
Published: September 2024

Scrotoliths, or “scrotal pearls,” are calcified fibrous loose bodies found within the tunica vaginalis, often seen during radiological evaluation or autopsies. Chronic inflammation due to trauma, parasitic infestations, and torsion and subsequent detachment of the appendices of the testis or epididymis are postulated mechanisms suggested for their formation. They are benign but can mimic a tumor. Scrotoliths can be diagnosed with high-resolution ultrasonography. Here, we report a case in which, during routine dissection, two scrotoliths were found within the tunica vaginalis of the left testis in an elderly male cadaver. Histologically, the central portion of the scrotoliths exhibited concentric collagen lamellae that enclosed calcified remains of tissue debris. There were no arterioles, venules, or microfilarial larvae seen within them. Awareness about the histological findings can help understand the mechanism that led to their formation.
Application of the bow-tie analysis to improve patient safety – a lesson learned from clinical practice
Authors: Dimova Rositsa , Raycheva Ralitsa , Pavlova Pavlina
Published: September 2024

Aim: This study aimed to assess the risk management of drug safety in an operating theater setting within a hospital-based treatment facility.

Materials and methods: This is a case study detailing a single patient. The bow-tie model was modified for analyzing medication errors in anesthesiology practice and implemented in the operating room of the university hospital. The diagram was created using well-established methods. The data was gathered using an online portal (www.rsps.bg) designed to evaluate hospital safety culture and report incidents.

Results: The Striped Bow Tie® methodology-built model illustrated the primary reasons for the medication error. The risk score was estimated to be 12 based on the specified parameters. The severity is rated on a 4-point scale ranging from catastrophic (4), critical (3), marginal (2), to negligible (1). The likelihood is assessed on a 5-point scale from frequent (5), probable (4), occasional (3), moderate (2), to unlikely (1). Preventive methods were suggested to minimize the risk, avert the incident, and manage the process.

Conclusion: The bow-tie approach is suitable and simple to apply in hospital anesthesia practice and serves as an essential instrument for analyzing medication safety risks. The analysis demonstrated systemic errors that led to the incident, including unrealized potential for continuing medical education and transforming the hospital into a place where clinicians can constantly learn by reporting adverse events and medical errors.

Published: September 2024

Nectriaceae is a highly diverse family, and members have a worldwide distribution, particularly in warm temperate to tropical regions. During the survey of fungal diversity in different habitats in Yunnan province, China, two new species isolated from soil and air respectively, namely Atractium yunnanensesp. nov. and Nalanthamala xishuangbannaensissp. nov., were proposed based on morphological comparisons and the multi-gene phylogenetic analyses of combined ITS, LSU, rpb2, and tub2 sequence data. Phylogenetically, both species clustered in a monophyletic clade within Nectriaceae with strong support. A. yunnanense is characterized by synnematous conidiophores, pale olivaceous-green, clavate to oblong-ellipsoidal, multi-septate conidia, and pale olivaceous-green chlamydospores. N. xishuangbannaensis has acremonium-like or penicillium-like conidiophores and either obovate or ellipsoidal, cylindrical or fusiform conidia. Full descriptions, illustrations, and a phylogenetic tree showing the phylogenetic position of the two new species were provided.

Authors: Sia Rose K. , Eaddy Isabel , Beydoun Hind , Eaddy Jennifer B. , Hogan Alexis , Skurski Zachary P.
Published: September 2024

Purpose:

To compare early visual quality of small incision lenticule extraction (SMILE) versus laser in situ keratomileusis (LASIK) in terms of low contrast acuity.

Methods:

A secondary analysis was performed using a harmonized dataset derived from two completed prospective cohort studies on active-duty military service members undergoing either SMILE (n = 37), wavefront-guided (WFG) LASIK (n = 51), or wavefront-optimized (WFO) LASIK (n = 56). Night vision and photopic and mesopic low contrast visual acuity (LCVA) up to 3 months postoperatively were compared between groups.

Results:

Compared to SMILE-treated eyes, WFG LASIK–treated eyes had significantly better night vision and photopic LCVA at 1 month postoperatively (beta = −0.039,
P
= .016; beta = −0.043,
P
= .007, respectively). WFO LASIK–treated eyes had significantly better photopic LCVA at 1 month postoperatively (beta = −0.039,
P
= .012) but had worse mesopic LCVA at 3 months postoperatively (beta = 0.033,
P
= .015) versus SMILE-treated eyes.

Conclusions:

SMILE and LASIK, on either a WFG or WFO laser platform, yielded excellent outcomes, but LCVA seemed to recover quicker following LASIK compared to SMILE.

Long-term Visual Outcomes in Patients With Idiopathic Macular Hole Surgery
Authors: Steinkerchner Megan S. , Sharma Neha , Russell Matthew W. , Maatouk Christopher , Talcott Katherine E. , Singh Rishi P.
Published: September 2024

Background and Objective

This study assesses long-term outcomes following surgical repair of idiopathic full-thickness macular holes (FTMHs) in patients with at least 5 years of postoperative follow-up.

Patients and Methods

A retrospective study evaluated patients diagnosed with idiopathic FTMH who received surgical repair at a single tertiary center with at least 5 years of postoperative follow-up. Data collection included demographic and preoperative characteristics along with macular hole structural integrity as determined by spectral-domain optical coherence tomography (OCT). Functional and structural improvement were assessed by collection of visual acuity and findings on OCT at determined time points until 9 years of follow-up.

Results

The study comprised 90 eyes of 80 patients with a mean age of 67.2 ± 6.8 years, with an average postoperative follow-up of 80.8 ± 17.4 months (range 54 to 130 months). The mean macular hole diameter was 239.7 µm ± 92.2. Macular hole reoperation occurred in four eyes (4%) at a mean duration of 5.5 ± 6 months (range 0.3 to 13 months). Over the study duration, ellipsoid zone (EZ) integrity was maintained in 67.8% of eyes, with an absence of intraretinal fluid (IRF) in 96% on final OCT. The preoperative mean Early Treatment Diabetic Retinopathy Study (ETDRS) best visual acuity (BVA) of 51 improved to a mean BVA of 76 at 5 years postoperatively, with an average gain of 24 letters at one year that remained stable over 5 years (
P
< 0.05). Eight years after surgical repair, more than 80% of patients achieved a BVA > 65.

Conclusions

Pseudospectral method for fourth-order fractional Sturm-Liouville problems
Authors: Jebreen Haifa Bin , Hernández-Jiménez Beatriz
Published: September 2024

Fourth-order fractional Sturm-Liouville problems are studied in this work. The numerical simulation uses the pseudospectral method, utilizing Chebyshev cardinal polynomials. The presented algorithm is implemented after converting the desired equation into an associated integral equation and gives us a linear system of algebraic equations. Then, we can find the eigenvalues by calculating the roots of the corresponding characteristic polynomial. What is most striking is that the proposed scheme accurately solves this type of equation. Numerical experiments confirm this claim.
A new $ H_{\infty} $ control method of switched nonlinear systems with persistent dwell time: $ H_{\infty} $ fuzzy control criterion with convergence rate constraints
Authors: Geng Han , Zhang Huasheng
Published: September 2024

This study aims to explore the problem of $ H_{\infty} $ fuzzy control with an adjustable convergence rate for switched nonlinear systems with time-varying delays under the persistent dwell time (PDT) switching. Compared to the widely studied dwell time (DT) switching or average dwell time (ADT) switching in existing literature, PDT switching provides a more comprehensive consideration of the switching frequency and has a broader range of applicability. Subsequently, by combining the interval stability definition, T-S fuzzy model, PDT technique, and Lyapunov-Krasovskii (L-K) functional, a new $ H_{\infty} $ fuzzy control criterion for adjusting the convergence rate of switched nonlinear systems with time-varying delays is proposed. This criterion enables the development of a novel method for constructing $ H_{\infty} $ fuzzy controllers, which can regulate the system's convergence rate and achieve the specified $ H_{\infty} $ performance. Combining the above methods, an algorithm is introduced to precisely control the convergence rate of the target system. Finally, the effectiveness of this method is validated through a control example of a single-link robot arm.
Fuzzy collineations of 3-dimensional fuzzy projective space from 4-dimensional fuzzy vector space
Authors: Kahriman Elif Altintas
Published: September 2024

In this paper, the fuzzy counterparts of the collineations defined in classical projective spaces are defined in a 3-dimensional fuzzy projective space derived from a 4-dimensional fuzzy vector space. The properties of fuzzy projective space $ (\lambda, \mathcal{S}) $ left invariant under the fuzzy collineations are characterized depending on the membership degrees of the given fuzzy projective space and also depending on the pointwise invariant of the lines. Moreover, some relations between membership degrees of the fuzzy projective space are presented according to which are of the base point, base line, and base plane invariant under a fuzzy collineation. Specifically, when all membership degrees of $ (\lambda, \mathcal{S}) $ are distinct, the base point, base line, and base plane of $ (\lambda, \mathcal{S}) $ are invariant under the fuzzy collineation $ \bar{f} $. Conversely, if none of the base point, base line, or base plane remain invariant, then the system becomes crisp in $ (\lambda, \mathcal{S}) $. Additionally, some relations between the membership degrees of the fuzzy projective space, concerning the invariance of the base point, base line, and base plane, are presented.

Authors: Yan Zhilong , Zhang Aixin
Published: September 2024

This article explores the evolution of totemic symbolism in contemporary visual art and its profound link with religious concepts, particularly the image of God. It examines how artists reinterpret sacred themes through totems, reflecting both historical religious traditions and modern societal transformations. Through a review of totemic representations from ancient to contemporary artworks, this study illuminates the evolving portrayal of divine figures – from traditional religious icons to more personalised spiritual symbols. This evolution not only signifies changes in artistic expression but also suggests a deepening societal understanding of divinity. The analysis highlights the totem’s role as a mediator between the human and the divine, offering insights into the spiritual connections that transcend conventional religious frameworks. This research not only enriches the discourse on the relationship between art and religion but also underscores the dynamic interaction between cultural heritage and contemporary artistic exploration.Contribution: This study enriches the field of art history and religious studies by tracing the transformative representation of totems in art from ancient symbolism to modern reinterpretations. It underscores the totem’s role as a dynamic symbol in contemporary visual culture, facilitating deeper spiritual connections and dialogues across various cultural and religious landscapes. The findings of this study provide a nuanced understanding of how contemporary art mediates complex theological concepts, thus offering new perspectives on the intersection of art, religion and spirituality.
Histopathological evaluation and grading for prostate cancer: current issues and crucial aspects
Authors: Agosti Vittorio , Munari Enrico
Published: September 2024

A crucial aspect of prostate cancer grading, especially in low- and intermediate-risk cancer, is the accurate identification of Gleason pattern 4 glands, which includes ill-formed or fused glands. However, there is notable inconsistency among pathologists in recognizing these glands, especially when mixed with pattern 3 glands. This inconsistency has significant implications for patient management and treatment decisions. Conversely, the recognition of glomeruloid and cribriform architecture has shown higher reproducibility. Cribriform architecture, in particular, has been linked to the worst prognosis among pattern 4 subtypes. Intraductal carcinoma of the prostate (IDC-P) is also associated with high-grade cancer and poor prognosis. Accurate identification, classification, and tumor size evaluation by pathologists are vital for determining patient treatment. This review emphasizes the importance of prostate cancer grading, highlighting challenges like distinguishing between pattern 3 and pattern 4 and the prognostic implications of cribriform architecture and intraductal proliferations. It also addresses the inherent grading limitations due to interobserver variability and explores the potential of computational pathology to enhance pathologist accuracy and consistency.
Serum Progesterone Levels on the Day of Human Chorionic Gonadotrophin Trigger, and its effects on the Outcome of In Vitro Fertilization, and Embryo Transfer: A Two-Center Study
Authors: Onuh Monday Augustine , Ameh Nkeiruka , Ejenobo Tolulope Ejiroghene David , Afolabi Adeniyi stephen , Wada Ibrahim
Published: September 2024

Introduction:

Gonadotrophin-releasing hormone analogs were expected to make preovulatory progesterone (P4) elevation rare during in vitro fertilization (IVF) cycles, but despite its widespread use, subtle rise in P4 levels on the day of ovulation trigger has a documented prevalence of 5%–38%. The effect of preovulatory progesterone levels on IVF outcomes is still controversial and published data from West Africa is sparse.

Materials and Methods:

This was a prospective observational study of 107 women who underwent IVF in both Garki and Nisa hospitals in Abuja, Nigeria. A serum sample was obtained from participants on the day of human chorionic gonadotrophin administration for a single determination of progesterone level. Oocytes retrieved, biochemical pregnancy, and clinical pregnancy were the primary outcomes.

Results:

The mean P4 on human chorionic gonadotrophin (hCG) trigger day was 2.07 ± 0.24 ng/mL and 48 (44.9%) had P4 > 1.5 ng/mL. There was no relationship between P4, and the number of oocytes retrieved but implantation, biochemical pregnancy, and clinical pregnancy were significantly diminished when P4 >1.5 and <1 ng/mL: biochemical pregnancy (27.3% vs. 61.5% vs. 14.6%, χ2 = 17.896; P < 0.0001), clinical pregnancy (24.2% vs. 50.0% vs. 14.6%, χ2 = 11.041; P = 0.004).

Conclusion:

Pregnancy rates are diminished when P4 on hCG trigger day is elevated.

ABSTRACT

Introduction:

Legislative assemblies often provide a platform for legislators to question the government during question hours, which are crucial for governance However, question hours remain understudied, especially when addressing health policy and systems related issues in lower- and middle-income countries. This study assesses the 14th Kerala Legislative Assembly questions, focusing on health-related areas to provide insights for health policy formulation and decision-making processes.

Materials and Methods:

We sourced and transcribed all starred questions (346) related to health that were answered by the health minister in the 14th Legislative Assembly between 2016 and 2021 from the archives of the assembly website. We conducted a thematic analysis of these questions and mapped them into various themes, guided by the World Health Organization building blocks framework.

Results:

About 7.8% of all questions (N = 4404) were related to health (N = 346). Of these questions, the majority were directly related to service delivery (43.4%), followed by health information (16.5%). Health financing, food safety, and human resources were the least discussed topics throughout the assessed period within the state. The legislators primarily focussed on health services and health information, with less attention given to health financing, food safety, and human resources regardless of constituency or political affiliation.

Discussion:

This study underscores the need for a balanced approach to public health issues, highlighting the importance of legislators to priortizing health services and information, while also addressing health financing, food safety, and human resources. This would enable a robust and resilient public health system to effectively address diverse health concerns.

Published: September 2024

ABSTRACT

Introduction:

Adolescence is a crucial part of life characterised by rapid body changes that can be influenced by perceptions and misinformation regarding their body image. Body image is usually associated with self-esteem and self-worth. Therefore, it is important to address this issue at this transitional time. This study aims to understand the perception of body image and its correlation with nutritional status among first-year medical students.

Methods:

A cross-sectional study was conducted among first-year medical students enrolled in the MBBS curriculum. Data related to perception of body image were collected through a self-administered, pre-tested questionnaire. Height and weight were taken by the principal investigator at the time of data collection and body mass index (BMI) was calculated according to Asian criteria for BMI. Kappa statistics were used for the agreement between self-perceived body image and BMI.

Results:

A total of 234 out of the 250 students enrolled in the first year gave consent for the study. The median (interquartile range [IQR]) age of the students was 18 (17–19) years and 72% were male students. One-fourth of the students were dissatisfied with their weight (26.9%) followed by height (25%). The Kappa statistics for agreement between BMI and self-perception about body weight was 0.373 (95% confidence interval [CI], standard error (SE) of Kappa = 0.048), showing poor agreement.

Conclusion:

One-fourth of the students were dissatisfied with their physical appearance. The agreement between perceived body weight and nutritional status was poor (64.53%).
