Strategy for Developing Medical Inorganic-Organic Hybrid Biomaterials through the Improvement of Sericulture as a Producer of Renewable Active Biological Raw Materials
Authors: Karyasa I Wayan , Kusumawati Enike Dwi
Published: January 2025

The need for biomaterials is increasing as more and more health problems become more and more complex. Progress in the field of medical biomaterials is also accelerating, but the provision of renewable biomaterials continues to be of concern to the world as awareness of sustainable development in the field of chemistry and health. Various strategies in the development of medical biomaterials were studied through a narrative review of the literature. One of them is the strategy of developing inorganic-organic hybrid medical biomaterials through the cultivation of silkworms as producers of renewable biomaterial raw materials. Sericulture can produce active biomaterials such as sericin, fibroin and other renewable materials and those biomaterials can be combined with inorganic nanoparticles to produce medical functional biomaterials on an ongoing basis. The addition of antibacterial bioactive materials such as natural dyestuffs and inorganic nanoparticles of anti-bacterial agents can increase the productivity and quality of antimicrobial biomaterials produced by the cultivation of silkworms.

Authors: Gholap Veena , Bardhan Navoneela , Desai Shyamolie , Rastogi Abhinav , Jadhav Bindoo
Published: January 2025

Background:

Overwhelming or prolonged stress causes impairment in various functional domains. Stressful situations at the workplace may be contributed by poor interpersonal relationships, shift work, poorly defined goals, incompatibility between employees’ skills and the assigned work, etc. Occupational stress may further deteriorate productivity at work, leading to workplace accidents, substance use, absenteeism, and conflicts. Hence, it is important to assess the stress levels among employees, recognize contributory factors and promote mental health at the workplace.

Aims:

(i) To assess the level of stress among the employees of general medical colleges and hospital. (ii) To determine the factors influencing the level of stress.

Methodology:

This cross-sectional observational study was conducted in a general medical college and hospital in Mumbai. Two hundred and six participants were enrolled, consisting of doctors, nurses, administrative staff, and class IV workers. Sociodemographic factors were assessed via a semi-structured pro forma. Information related to occupational stress was collected via the Brief Stress Questionnaire.

Results:

The prevalence of occupational stress was 60%. The mean BSQ score was 25.485. Young adults and males had a higher mean BSQ score. Doctors, nurses, and class IV workers perceived a higher level of stress (27.62, 27.88, and 23.559, respectively). The most prevalent contributors to occupational stress were deadlines and time pressures (12.62%), too many jobs to do at once (12.13%), etc.

Conclusion:

Occupational stress is prevalent in varying intensities among the health-care employees. Identifying and addressing the contributory factors would help in the prevention of burnout among health-care workers.

Authors: Kota Sushmitha , Shah Rakesh Jayantilal
Published: January 2025

Background:

Music therapy is a type of expressive arts therapy that uses music to improve and maintain the physical, psychological, and social well-being of individuals. Studies have shown an impact on depression and anxiety, while there is very little literature that has focused on the negative symptoms of schizophrenia; hence, we aim to study the effectiveness of music therapy in patients with negative symptoms of schizophrenia.

Materials and Methods:

Seventy-nine patients were randomized to get 40 cases and 39 controls. Cases received music interventions in addition to standard treatment, while controls received only standard treatment. Both cases and controls’ negative symptoms were assessed with the Scale for the Assessment of Negative Symptoms (SANS) before and after music therapy. The Chi-square test, independent t-test, and Mann–Whitney U test were used to determine the associations.

Results:

We had 36 cases and 31 controls at the end of the music therapy, and there was an association of application of music therapy in negative symptoms of schizophrenia with occupation among cases (P = 0.037). There were huge differences in negative symptoms pre- and postmusic therapy among cases (31.44 ± 9.21) when compared to controls (4.42 ± 5.97) and significant association of affective flattening, alogia, avolition, anhedonia/asociality, and attentional impairment with music therapy (P < 0.00001 each).

Conclusions:

There is a significant association of each domain of negative symptoms of schizophrenia with music therapy and also improves work efficiency, irrespective of age, gender, marital status, education, and background of the patient with music therapy.

Authors: Inchauspe Adrián Ángel , Saidman Gabriela Roxana
Published: January 2025

Thirty-seven years have passed since the first K-1 resuscitation maneuver implementation next to both basic and advanced CPR failure and Prof. Inchauspe has consistently continued such unique research recovering impending death situation victims in the most varied scenarios. After a dozen publications on the issue –mostly in World Journal of Critical Care Medicine and Hainan University Medical Editorial in China, the number of rescues increased to more than 195 cases. Having been contacted by experts in Ayurvedic medicine from India, the authors made a comparative analysis between said K-1 Yongquan and the Talahridaya points, and realized that not only are they located at the very same place for stimulation, but they are also integrated in the Reconciliation Vessel, a new Marvelous meridian discovered by Prof. Inchauspe within the Ancient Chinese classics. The following paper will show a statistical analysis made by Prof. Inchauspe and Dr. Saidman about the possible future impact that would result from the inclusion of the aforementioned maneuver in life support protocols.
A Rare Case of an Inferior Gluteal Artery Causing Compressive Vascular Neuropathy of the Sciatic Nerve Presenting as Foot Drop
Authors: Wahane Madhugandha , Agrawal Amit , Sureka Rajendra Kumar
Published: January 2025

Foot drop is most frequently caused by peroneal or sciatic nerve injury. The most common causes of nerve injury are trauma, compression, tumor, or entrapment. Vascular compressive neuropathy was extensively studied by Hultborn and Kjellman, and they observed that gluteal artery aneurysm can present with sciatica-like symptoms. Saritha et al. have studied the anatomical variation in the bifurcation of the sciatic nerve and its presentation. So far, there are no case reports on a vascular anomaly in association with an anatomical variation leading to compressive vascular neuropathy. We present a rare case of foot drop caused by compressive vascular neuropathy of the sciatic nerve, caused by a traversing inferior gluteal artery.

Authors: Boz Hatice Eraslan , Tüfekçi Işıl Yağmur , Akkoyun Müge , Koçoğlu Koray , Akdal Gülden
Published: January 2025

ABSTRACT

Objective:

This study examined saccadic reaction time (SRT) in visually guided saccades according to age and its relationship with attention and working memory.

Materials and Methods:

The study participants were divided into three groups: young adulthood (18–39 years), middle adulthood (40–59 years old), and older age groups (over 60 years). A total of 85 participants, including 20 young aged, 26 middle aged, and 39 older aged, participated in the study. SRT was recorded using the EyeLink 1000 Plus eye tracker, and 32 trials were conducted. In addition, neuropsychological tests assessing attention and working memory including the Trail Making Test (TM), Digit Span (DS), and Stroop test were applied to the participants.

Results:

SRTs were prolonged in the middle adulthood (P = 0.026) and older age group compared with young adulthood (P = 0.002). However, SRT did not differ between the middle adulthood and older age groups (P > 0.05). In addition, SRT was moderately positively and negatively correlated with TM-A (r = 0.355, P = 0.001), TM-B (r = 0.460, P < 0.001), TM-B-A (r = 0.433, P < 0.001), and DS backward (r = −0.409, P < 0.001) that is visual attention and working memory.

Conclusion:

SRT may be affected by age. This appears to be part of the visual attention and working memory associated with the saccadic decision-making process.

Authors: Shahba Samar A. , Ahmed Amira Y. , Eldib Ayman S. , Ibrahim Ibrahim S.E.D.
Published: January 2025

Background

B7-H4 represents a recently identified B7 family member of molecules that exhibits a crucial impact on the tumor microenvironment regulation since it is deemed to inhibit both innate immunity as well as T-cell responses.

Aim

This work was aimed at assessing B7-H4 as a diagnostic marker in malignant pleural effusion (MPE).

Patients and methods

Our prospective analytic controlled case study involved 50 patients aged above 12 years old with parapneumonic, tuberculous, and MPE. All participants went through an equal categorization into two groups: group I: malignant cases with MPE. Group II: benign cases having benign PE. B7-H4 was measured in pleural fluid (PF) and serum by enzyme-linked immunosorbent assay.

Results

B7-H4 PF, as well as serum levels, exhibited significantly higher values within group I, possessing a significant positive correlation between both. The cut-off point of the PF level of B7-H4 in the diagnosis of MPF was 42 ng/ml, with a sensitivity of 88%, specificity of 80%, positive predictive value of 81%, negative predictive value 87%, and area under the receiver operating characteristic curve 0.939. While the serum level of B7-H4 cut-off was 33 ng/ml, sensitivity 80%, specificity 72%, positive predictive value 74%, negative predictive value 78%, and area under the curve 0.916.

Conclusion

High sensitivity and specificity of B7-H4 were observed while detecting MPE. The PF level of B7-H4 is more sensitive, specific, and accurate in the diagnosis of MPF than the serum level of B7-H4.

Authors: Farouk Heba S. , Elseht Rabab M. , Allam Waleed A. , Naseef Mohamed H.
Published: January 2025

Background

The thickness of the corneal epithelium can be precisely measured using anterior segment optical coherence tomography (AS-OCT).

Aim

This study aimed to conduct an AS-OCT evaluation of changes in the corneal epithelial thickness following collagen cross-linking (CXL).

Patient and methods

This prospective interventional study utilized 23 eyes from 13 cases who underwent treatment for progressive keratoconus (KC) with epi-off corneal CXL according to the Dresden’s Protocol.

Results

After 6 months postoperative the central minimum epithelial thickness (0.0–2.0 mm) showed a statistically significant increase, while the mid-peripheral (5.0–7.0 mm) showed a statistically significant decrease compared with the preoperative level. The central average epithelial thickness (0.0–2.0 mm) showed statistically nonsignificant increase, while the mid-peripheral and peripheral (5.0–7.0, 7.0–9.0 mm) showed a statistically significant decrease in comparison to the level before the operation. At 6 months postoperative, a decrease in Mean k was associated with statistically significant elevation in average central and paracentral epithelial thickness (0.0–2.0, 2.0–5.0 mm) as compared with the preoperative level (negative correlation). At 6 months postoperative, reduction in thinnest pachymetry was associated with statistically significant increase in central and paracentral average epithelial thickness (0.0–2.0, 2.0–5.0 mm) (negative correlation) as compared with the preoperative and 3 months postoperative.

Conclusions

With AS-OCT, it is simple to track changes in the epithelium over time. Epithelial remodeling occurs after CXL in the areas of protrusion and thinning. The thickness of the epithelium is greatest at the cone’s base and diminishes as one moves away from it.

Authors: Elhashash Esraa R.K. , Elbadry Amr M.T. , Elshahawy Alshimaa Z. , Ammar Alshimaa M.
Published: January 2025

Background

The Dixon method for fat/water separation employs a technique for achieving consistent fat suppression by utilizing water-only reconstruction. The fat-only Dixon technique is a tool for identifying microscopic fat and assessing pathological lesions of concern.

Aim

To investigate the MRI Dixon fat fraction role in assessing fat deposition among nonalcoholic fatty liver disease (NAFLD) cases and correlation with ultrasonography (USG).

Patients and methods

This study included 30 cases, with an age range falling between 19 and 80 years, both sexes. We included those with one or more risk factors for NAFLD in which diffuse hepatic steatosis or normal liver was identified utilizing USG of the abdomen. Participants were examined using USG examination and MRI.

Results

Good agreement (k=0.615) between two imagining methods (MRI T1 Dixon and USG) in detecting fatty liver with significant difference between diagnostic confidence (accuracy) of MRI T1 Dixon and USG in detection of fatty liver (P=0.005). A significant variance was observed among the grading of fatty liver by MRI T1 Dixon and the presence of METs criteria and alanine aminotransferase level (P<0.05). By USG, a moderate agreement between fatty liver grading utilizing MRI T1 Dixon and fatty liver grading utilizing USG (k=0.526).

Conclusions

Dixon MRI was a noninvasive method for quantifying fat fraction in NAFLD. When comparing the fatty liver grading on USG with the assessment of liver fat with MRI T1 Dixon of the liver, there was a significant overlap in the fat percentage within each grade.

Authors: Elsayed Amal S.A. , Aldorghami Alaa A. , Allam Walid A. , Sharaf Amr F.
Published: January 2025

Background

Albumin eye drops (AED) can be effective in the healing of corneal epithelial defects. Albumin is the main protein component of autologous serum and therefore may be useful in the treatment of ocular surface diseases such as corneal ulcers and epithelial defects.

Aim

This work aimed to study the effect of human AED as adjunctive therapy in the treatment of persistent corneal epithelial defects (PCEDs).

Patients and methods

This prospective study was conducted in 20 patients aged 18–60 years, of both sexes, with PCEDs that did not respond to standard medical treatment for 10 to 14 days. All patients underwent slit-lamp examination, fundus examination, intraocular pressure measurement (digital), corneal swab, culture, and sensitivity.

Results

There was a significant positive correlation between the duration of medical therapy with the persistent antiepithelial defect AED and the size of the persistent epithelial defect at presentation (P<0.05). There was significant improvement in pain sensation, ciliary injection, persistent epithelial defect size, corneal, and stromal infiltration during the study period. There was no significant association between the duration of continuous ant epithelial drug therapy AED and stromal infiltration at presentation (P=0.627).

Conclusion

The promising therapeutic effects of AED on the corneal epithelium have been demonstrated. Albumin has shown a therapeutic effect in the treatment of PCEDs.

Authors: Salem Helal Mohammed , Elbassat Hanan Ahmed , El Bendary Amal Said , El_Sharawy Shimaa Mahmoud
Published: January 2025

Background

Von Willebrand factor (VWF) is commonly elevated in patients with cirrhosis. Moreover, it is a predictor of morbidity and mortality.

Aim

We aimed to examine whether Egyptian cirrhotic patients have a higher risk of spontaneous bacterial peritonitis and its associated complications based on their von Willebrand factor level.

Patients and methods

This cross-sectional study included 90 hepatitis c virus (HCV)-positive cirrhotic patients. Group A, consisted of 30 patients without spontaneous bacterial peritonitis; Group B, consisted of 30 patients with spontaneous bacterial peritonitis; and Group C, consisted of 30 patients with spontaneous bacterial peritonitis complicated by hepatorenal syndrome. All study participants had paracentesis samples for diagnostic testing. Serum von Willebrand factor was determined using enzyme-linked immunosorbent assay. Model for end-stage liver disease score, von Willebrand factor antigen/thrombocyte ratio (VITRO) and Child-Pugh stages were calculated.

Results

Von Willebrand factor level at a cut-off value > 196.5 international unit/deciliter (IU/dL) could predict the presence of spontaneous bacterial peritonitis. Moreover, it has been found that von Willebrand factor cut-off value of >244 IU/dL can predict hepatorenal syndrome. With VITRO score cut-off >2.26, the presence of spontaneous bacterial peritonitis can be predicted. Also, cut-off value>2.60 can be used to predict the occurrence of hepatorenal syndrome as a complication of spontaneous bacterial peritonitis.

Conclusion

Von Willebrand factor could be a reliable noninvasive predictor of spontaneous bacterial peritonitis and Hepatorenal syndrome in cirrhotic patients.
Relation of postoperative refraction and anterior chamber depth changes after uneventful phacoemulsification
Authors: Mohammed Mohammed A.
Published: January 2025

Background

Following cataract surgery, the focus changed from relieving blindness to achieving precise refractive correction and rapid recovery. A lot of factors influence the visual outcome. The variance in postoperative anterior chamber depth (ACD) is one of the essential factors.

Aim

To record the differences in postoperative ACD measurements and its effects on postoperative refraction in individuals who had uneventful cataract surgery at Suez General Hospital.

Patіents and methods

Fifty eyes from fifty patients who underwent uneventful phacoemulsification by the same surgeon. Using the ocular biometer The IOLMaster 500 from ZEISS, (ACD) were assessed pre and postsurgery, 1 and 3 months after the procedure. The postoperative spherical equivalent were recorded.

Results

Mean age was (58.7±7.5) years. a highly significant difference in ACD values between preoperative and 1 and 3 months post-surgery (P<0.0001). While the ACD difference between 1 and 3 months postsurgery was insignificant (P=0.332). Fourteen (28%) of the eyes had a myopic spherical refractive error, 24 (48%) had a hyperopic refractive error, and 12 (24%) had no refractive error. An inverse association (r=–0.243, P=0.039) between the myopic sphere refractive errors and the variation in ACD.

Conclusіon

A high incidence of postoperative hyperopic shift spherical errors was linked to more extensive preoperative ACD measurements associated with less ACD deepening. While a more significant incidence of postoperative myopic shift spherical errors was linked to a small preoperative ACD with a greater degree of postoperative ACD deepening; therefore, postoperative ACD changes have a significant impact on postoperative refraction.

Authors: Zubelevich Oleg Eduardovich
Published: January 2025

Рассматривается задача о движении массивной частицы на горизонтальной шероховатой плоскости. На частицу кроме силы сухого трения действует сила притяжения, пропорциональная расстоянию до притягивающего центра. Такая сила может быть вызвана линейно упругой пружиной. Эта заметка посвящена решению следующего вопроса: "Верно ли, что при любых начальных условиях частица остановится за конечное время?" Несмотря на то, что ответ "Да" физически очевиден, формальное доказательство этого факта оказывается неожиданно сложным. В конечном счете все сводится к исследованию асимптотического поведения решений в окрестности вырожденного положения равновесия некоторой гладкой нелинейной системы. Кроме того, в данной заметке сформулирована открытая проблема.

Authors: Jin Hanna , Kim Woojun , Kim Sung Hye
Published: January 2025

Neurocysticercosis, a central nervous system infection caused by the zoonotic parasite Taenia solium, is a leading cause of acquired epilepsy worldwide. It is common in areas with extensive pig farming and pork consumption. This report presents an unusual case of neurocysticercosis in a 28-year-old male from Timor-Leste, a region of nonendemicity for human cases of Taenia solium. The patient, who had experienced seizures precipitated by headaches, was admitted to the hospital on June 15, 2020. Comprehensive examinations, including neuroimaging, identified multiple cystic lesions suggestive of neurocysticercosis. Initial treatment with praziquantel and prednisolone, as well as levetiracetam, alleviated symptoms. However, symptom recurrence after 5 months prompted additional treatment cycles. This case underscores the importance of increased clinical vigilance in patients from areas of nonendemicity and the challenges in managing neurocysticercosis because of its evolving nature. The global health initiatives aimed at enhancing disease surveillance for human taeniasis are crucial for refining our knowledge on neurocysticercosis.

Published: January 2025

The study assessed the levels of radiation exposure due to environmental radioactivity and heavy metal contamination at the central solid waste dumpsite in Abakiliki, Ebonyi State and its health impact on surrounding communities. Soil samples collected from landfills/dumpsites, farms, and control sites were assessed to determine environmental radioactivity and heavy metal concentrations, and compared to the control site values. The radioactivity concentration was determined using a NaI(Ti) gamma spectrometer. The estimated radiological hazard indices from the dumpsite and farmland showed that the average values of Radium Equivalent (Req), and excess lifetime cancer risk are 146 Bq kg-1 and 1.445 x 10-3 respectively. The average concentration of heavy metals in soil samples was evaluated using an atomic absorption spectrophotometer (AAS). The concentration of heavy metals in studied samples showed that Pb > Fe > Cu > Zn > Co > Ni > Cd > Cr > Hg > As. Soil contamination was based on the geo-accumulation index (Igeo), Potential ecological risk coefficient (RI), Chronic daily take (CDI), Total carcinogenic risk index (TCRI), Total hazard quotient (THQ) and pollution load index (PLI). The average values of Igeo, CDI, TCRI, THQ and PLI for dumpsites and surrounding farms were 2.01, 207.19, 6.1 x 10-2, 2.66, 0.95 and 1.33 respectively. Generally, high concentrations of Pb and Fe were observed at the dumpsites and surrounding farmlands have potential negative health implications for the health of humans and plants around the dumpsite.

The review of Kéž je všecko ku prospěchu obce! (May everything be to the benefit of the community!), published by Academia and OIKOYMENH, editor Petr Blažek, focuses on four themes: what do the documents say about Patočka, about the secret police, about the fate of Patočka’s textual estate, and about the post-November iinvestigation of the repressive measures taken against Patočka. This study draws attention, among other things, to Patočka’s intention to depart to West Germany in 1976, the influence of the misidentification of the two Chvatíks on the successful progress of work on the publication of Patočka’s texts, Karel Kosík’s plan to revise the Heretical Essays and Two Studies on Masaryk, and above all the overlooking, by the editor of this volume (and the investigators from the 1990s), of the climax of the secret police repression against Patočka on March 2, 1977.

This study assessed the impact of crop diversification within no-till crop rotations on soil organic carbon and total nitrogen stocks, as well as on labile (Carbon and Nitrogen in the particulate organic matter) and persistent (Carbon and Nitrogen in the mineral-associated organic matter) Organic matter fractions. The objective was to identify practical indicators for monitoring public policies promoting low carbon emission agriculture. Field experiment was conducted in 2014/2015 cropping season using a complete random block design. Seven treatments were evaluated: soybean/cotton (CONTROL); maize/soybean (M/Sb); soybean/maize+brachiaria (Sb/M+Br); soybean/millet+brachiaria/crotalaria spectabiliscotton (Sb/Mt+Br/CrsCt); soybean/cotton/common beans/millet+ brachiaria (Sb/Ct/Cb/Mt+Br); millet-cotton/ soybean/maize/crotalaria spectabilis (Mt-Ct/Sb/M/Crs); crotalaria-cotton/soybean/ sorghum+brachiaria/crotalaria ochroleuca+ brachiaria (Cr-Ct/Sb/Sg+Br/Cro+Br). Sampling was done in May 2020 on an Oxisol in a neotropical savanna of the Central West region of Brazil (Capivara Experimental Research Farm of Embrapa Rice and Beans, Santo Antônio de Goiás, Goiás State, Brazil). Treatment comparisons were made after correction for equivalent soil mass per soil layer. The C-POM, N-POM, C-MAOM, and N-MAOM fractions were obtained through granulometric physical fractionation. Total SOC and SOC stocks were inadequate indicators of the impact of crop rotations on SOC. However, the distribution of C and N among the soil organic matter (SOM) fractions (C-POM, N-POM, C-MAOM, and N-MAOM) was influenced by crop rotations. Rotations with greater crop diversity, including gramineae, had higher concentration of C and N in the particulate SOC (C-POM and N-POM). Differences in rotation composition also affected the C to N ratio, particularly in the POM fraction, which was higher in rotations involving brachiaria grass and maize. Most diversified rotations contributed to maintaining higher C-POM stocks.
Managing Tax Compliance Through Collective Action Framework in Decent Work and Economic Growth (SDG 8) Goal: Lesson from Three Indonesian Cities
Authors: Putra Fadillah , Sanusi Anwar , Rochmah Siti , Nugrahani Shinta Awalia Rizky
Published: January 2025

Objective: This study will examine how the government and citizens view taxes as a collective action in state governance for Decent work and economic growth (SDG 8) goal.
 
Method: This research used questionnaires with a purposive random sampling method to collect data, and the data was tested using Structural Equation Modeling with the Partial Least Squares (SEM-PLS) analysis.
 
Results and Discussion: The results of the goodness of fit test of the three research areas show a significant value. The SEM-PLS analysis of hypothesis model testing results shows that all hypotheses are accepted in all three cities, but there are 3 hypotheses were rejected in one of the cities. The results of this study show a strong causal relationship between high levels of local tax payment compliance in the context of collective action. The Taxpayer Awareness variable influences the Taxpayer Compliance variable in Madiun and Mojokerto cities; however, in Probolinggo City, Taxpayer Compliance is influenced by Collaborative Governance. Increasing tax compliance is crucial for socio-economic development and contributes to the SDG 8 goal.
 
Research Implications: Furthermore, the results showed that tax compliance is still in the low category. This challenges local governments to increase public awareness of the importance of paying taxes. Therefore, further research is needed to determine the collective action in increasing tax compliance warranted to achieve Indonesia's target of tax ratio rate.
Identity Construction of Dayak [Ethnic]: Citation and Thematic Analysis of Systematic Literature Review

Published: January 2025

Objective: This research examines the adaptive capacity of university public relations from a self-referential autopoiesis communication perspective. It explores how the university ecosystem and the rhetorical expressions produced by University- PR function as differentiation mechanisms within the organizational system in Makassar Regency
 
Theoretical Framework: This dissertation uses Niklas Luhmann's (2002) self-referential autopoiesis communication perspective to explore the adaptive capacity of Public Relations through the meaning of the university ecosystem and the expression of governance and rhetoric produced as differentiation of organizational science function systems.
 
Method: This research uses a radical constructivism paradigm with comparative case studies at three universities. Data collection techniques include observation, interviews, and focus group discussions with university leaders, directors, heads of Public Relations, and staff of Public Relations, while rhetorical production is tracked by media content analysis. Data were analysed by triangulation, reduction, presentation, and conclusion.
 
Results and Discussion: The research findings indicate that Public Relations at Unhas identifies environmental challenges by interpreting university autonomy and the PTN BH League, enhancing human resources, and fostering research and innovation as a Maritime continent campus, while temporarily achieving a World Class University ranking of 500-1000. In contrast, UINAM's Public Relations addresses sustainability issues within the Public Service Agency, aligning with the Chancellor's vision and responding to digital transformation. UMI's Public Relations focuses on institutional competition, partnership development, and maintaining Islamic identity, targeting improvements in Tridharma and aiming for a 500-1000 Asian World Class University ranking. Differences in governance structures reflect universities' complexities, with distinct coordination lines across institutions.
 
Research Implications: This study emphasizes that universities employ unique communication strategies that diverge from the conventional business and government focus in public relations research, revealing the need for a more nuanced understanding of their public relations practices.
 
Originality/Value: The research reveals that Unhas Public Relations tackles environmental issues through university autonomy and innovation, achieving a temporary World Class ranking. UINAM focuses on sustainability and digital transformation, while UMI emphasizes competition and Islamic identity, aiming for academic excellence. Governance structures vary, reflecting the complexities of each institution.
