RESUMO
OBJECTIVE: Multi-drug resistance (MDR) has notably increased in community acquired uropathogens causing urinary tract infections (UTIs), predominantly Escherichia coli. Uropathogenic E. coli causes 80% of uncomplicated community acquired UTIs, particularly in pre-menopausal women. Considering this high prevalence and the potential to spread antimicrobial resistant genes, the current study was conducted to investigate the presence of clinically important strains of E. coli in Pakistani women having uncomplicated cystitis and pyelonephritis. Women belonging to low-income groups were exclusively included in the study. Seventy-four isolates from urine samples were processed, phylotyped, and screened for the presence of two Single Nucleotide Polymorphisms (SNPs) particularly associated with a clinically important clonal group A of E. coli (CgA) followed by antibiotic susceptibility testing and genome sequence analysis. RESULTS: Phylogroup B2 was most prevalent in patients and 44% of isolates were positive for the presence of CgA specific SNPs in Fumarate hydratase and DNA gyrase subunit B genes. Antibiotic susceptibility testing showed widespread resistance to trimethoprim-sulfamethoxazole and extended-spectrum beta-lactamase production. The infection analysis revealed the phylogroup B2 to be more pathogenic as compared to the other groups. The genome sequence of E. coli strain U17 revealed genes encoding virulence, multidrug resistance, and host colonization mechanisms. CONCLUSIONS: Our research findings not only validate the significant occurrence of multidrug-resistant clonal group A E. coli (CgA) in premenopausal Pakistani women suffering from cystitis and pyelonephritis but also reveal the presence of genes associated withvirulence, and drug efflux pumps. The detection of highly pathogenic, antimicrobial-resistant phylogroup B2 and CgA E. coli strains is likely to help in understanding the epidemiology of the pathogen and may ultimately help to reduce the impact of these strains on human health. Furthermore, the findings of this study will particularly help to reduce the prevalence of uncomplicated UTIs and the cost associated with their treatment in women belonging to low-income groups.

Urinary tract infections (UTIs) are among the most prevalent bacterial infections affecting people in inpatient and outpatient settings. The current study aimed to sequence the genome of uropathogenic Escherichia coli strain CUI-B1 resourced from a woman having uncomplicated cystitis and pyelonephritis. Followed by deductive genomics towards potential drug targets using E. coli strain CUI-B1, strain O25b: H4-ST131, Proteus mirabilis strain HI4320, Klebsiella pneumoniae strain 1721, and Staphylococcus saprophyticus strain ATCC 15305 uropathogenic strains. Comparative genome analysis revealed that genes related to the survival of E. coli, P. mirabilis, K. pneumoniae, and S. saprophyticus, such as genes of metal-requiring proteins, defense-associated genes, and genes associated with general physiology, were found to be highly conserved in the genomes including strain CUI-B1. However, the genes responsible for virulence and drug resistance, mainly those that are involved in bacterial secretion, fimbriae, adherence, and colonization, were found in various genomic regions and varied from one species to another or within the same species. Based on the genome sequence, virulence, and antimicrobial-resistant gene dataset, the subtractive proteomics approach revealed 22 proteins mapped to the pathogen's unique pathways and among them, entB, clbH, chuV, and ybtS were supposed to be potential drug targets and the single drug could be utilized for all above-mentioned strains. These results may provide the foundation for the optimal target for future discovery of drugs for E. coli-, P. mirabilis-, K. pneumoniae-, and S. saprophyticus-based infections and could be investigated further to employ in personalized drug development.

Economy of Pakistan is heavily dependent upon agriculture and extensive use of pesticide is quiet common to enhance the crop yield. Imidacloprid is among the first choice pesticides in Pakistan and it has been reported that through run off along with water it ends up in water bodies affecting non target aquatic fauna. Through the present investigation, we are reporting the effects of Imidacloprid on the fatty acids composition of a non-target, commercially important carp: Labeo rohita. Fish were exposed to sub lethal concentration of Imidacloprid (120 mgL1) for 2, 4 and 8 days (short term) as well as for 16, 32 and 64 days (long term experimental conditions). Pesticide untreated controls were also maintained for each treatment. Following the specific Imidacloprid exposure, fatty acid composition (%) was determined in the muscle of all experimental groups by using gas chromatography. Fish exposed to Imidacloprid for 8 days had reduced Palmitic acid (p = 0.02) and elevated muscle Arachidic acid (p < 0.001) than control group. Labeo rohita exposed to the pesticide for 32 days had elevated muscle Oleic (p = 0.02) and Linoleic acid (p = 0.02) while fish exposed to Imidacloprid to 64 days had reduced muscle Palmitic (p = 0.04) and Oleic acid (p = 0.03). In conclusion, we are reporting that the exposure to sub lethal concentration of Imidacloprid disturb the muscle fatty acid composition of Labeo rohita that may affect its food quality. The effects were more pronounced under long term experimental conditions and were probably due to potentiating lipid peroxidation and disturbed fish metabolism upon Imidacloprid exposure.

Extreme cold environments, such as polar regions or high-altitude mountains, are known for their challenging conditions including low temperatures, high salinity, and limited nutrient availability. Microbes that thrive in these environments have evolved specialized strategies to survive and function under such harsh conditions. The study aims to identify, sequence the genome, perform genome assembly, and conduct a comparative genome-wide analysis of Acinetobacter sp. strain P1, which was isolated from the Batura glacier regions of Pakistan. A basic local alignment search tool of NCBI using 16 s RNA gene sequence confirmed the strain Acinetobacter following phylogenetic analysis revealed that strain P1 clustered with Acinetobacter sp. strain AcBz01. The high-throughput Genome sequencing was done by the NovaSeq 6000 sequencing system following de novo genome assembly reported 23 contigs, a genome size of 3,732,502 bp containing approximately 3489 genes and 63 RNAs (60 tRNA, 3 rRNA). The comparative genome analysis revealed that Acinetobacter sp. strain P1 exhibited the highest homology with the Acinetobacter baumannii ATCC 17978 genome and encompassed 1668 indispensable genes, 1280 conserved genes 1821 specific genes suggesting high genomic plasticity and evolutionary diversity. The genes with functional assignments include exopolysaccharide phosphotransferase enzyme, cold-shock proteins, T6SS, membrane modifications, antibiotic resistance, and set of genes related to a wide range of metabolic characteristics such as exopolysaccharides were also present. Moreover, the structural prediction analysis of EPS proteins reveals that structural flexibility allows for conformational modifications during catalysis, which boosts or increases the catalytic effectiveness at lower temperatures. Overall, the identification of Acinetobacter, a cold-adapted bacterium, offers promising applications in bioremediation, enzyme production, food preservation, pharmaceutical development, and astrobiology. Further research and exploration of these microorganisms can unlock their full biotechnological potential and contribute to various industries and scientific endeavors.

BACKGROUND: Hospitals and healthcare institutions should be observant of the ever-changing environment and be adaptive to learning practices. By adopting the steps and other components of organizational learning, healthcare institutions can convert themselves into learning organizations and ultimately strengthen the overall healthcare system of the country. The present study aimed to examine the influence of several organizational learning dimensions on organization culture in healthcare settings during the COVID-19 outbreak. METHODS: During COVID-19 crisis in 2020, an online cross-sectional study was performed. Data were collected via official emails sent to 1500 healthcare professionals working in front line at four sets of hospitals in Saudi Arabia. Basic descriptive analysis was constructed to identify the variation between the four healthcare organizations. A multiple regression was employed to explore how hospitals can adopt learning process during pandemics, incorporating several Dimensions of Learning Organizations Questionnaire (DLOQ) developed by Marsick and Watkins (2003) and Leufvén and others (2015). RESULTS: Organizational learning including system connections (M = 3.745), embedded systems (M = 3.732), and team work and collaborations (M = 3.724) tended to have major significant relationships with building effective learning organization culture. Staff empowerment, dialogues and inquiry, internal learning culture, and continuous learning had the lowest effect on building health organization culture (M = 3.680, M = 3.3.679, M = 3.673, M = 3.663, respectively). A multiple linear regression was run to predict learning organization based on the several variables. These variables statistically significantly predicted learning organization, F (6, 1124) = 168.730, p < .0005, R2 = 0.471, (p < .05). DISCUSSION: The findings concluded that although intrinsic factors like staff empowerment, dialogues and inquiry, and internal learning culture, revealed central roles, still the most crucial factors toward the development of learning organization culture were extrinsic ones including connections, embed system and collaborations. CONCLUSIONS: Until knowledge-sharing is embedded in health organizational systems; organizations may not maintain a high level of learning during crisis.

BACKGROUND: College is a critical time where students are more prone to engage in risky health behaviors known to negatively affect well-being, such as physical inactivity, stress, and poor dietary habits. A health promoting lifestyle is an important determinant of health status and is recognized as a major factor for the maintenance and improvement of health. This study was designed to assess the health-promoting lifestyle of students in health colleges and non-health colleges in Saudi Arabia. METHODS: A total of 1656 students participated in this descriptive cross-sectional study. Data gathering was conducted from November 2016 to February 2017 at King Saud University. Participating students completed a self-reported questionnaire that included questions regarding their demographic characteristics and their health-promoting behaviors. RESULTS: The majority of participants were females (70.4%), 20% of the participants were overweight and 11.3%, were obese. The analysis showed that there was a significant difference between health colleges and non-health colleges with regards to the factor of health responsibility. Students at both schools were found to have an inadequate level of adherence to recommendations regarding physical activity and healthy eating habits. The analysis also found that majority of the students in both colleges do not attend educational programs on health care. The model shows that gender, type of college, year in school, and family structure were significant predictors of the health lifestyle of students in Saudi Arabia. CONCLUSION: The results of the current study indicate that university students are leading unhealthy lives, where the majority of them have unhealthy eating habits and poor physical activity level. Universities are ideal settings for implementing health promotion programs. Therefore, planning and implementing programs to motivate students to be more responsible for their own health, to engage more in physical activity, and to practice healthy eating habits and other forms of wellness are of paramount importance.

This study aims to explore the association between functional health literacy and awareness for, beliefs, and attitudes of patients with colorectal cancer (CRC) and CRC screening test in Riyadh, Saudi Arabia. A total of 256 participants from two different tertiary level hospitals in Riyadh, Saudi Arabia were recruited in this study. The participants were interviewed by a trained researcher between October and December 2015. All respondents answered a three-part questionnaire which included demographic data, questions related to CRC awareness, attitude, behaviour, and short Test of Functional Health Literacy in Adults (STOFHLA). More than half of the participants had an inadequate awareness of functional health literacy skills (FHLS), 16.4 % had marginal of FHLS awareness and 17.6 % had adequate awareness about FHLS as assessed by the STOFHLA. Overall, the majority of the participants in both marginal and adequate aware groups showed a limited awareness about colorectal cancer screening and testing. A significant association was found on awareness of the patients about frequencies that they should have been tested for colorectal cancer and functional health literacy. No significant association was found between functional health literacy as assessed by STOFHLA and concerns of Faecal Occult Blood Test (FOBT) (p = 0.384) and sigmoidoscopy or colonoscopy might cause embarrassment (p = 0.089), harm (p = 0.917), and pain (p = 0.849). The present study revealed a low level of health literacy among Saudi adults in Riyadh region. Although the level of literacy was low, the bigger concern is that of the poor awareness and beliefs of Saudi adults about CRC and CRC screening.

BACKGROUND: The natural assimilation of the process through which health partners sustain long-term relationships is a key issue in maintaining social well-being, reducing health risk factors, and sustaining public health programs. One global initiative in building effective healthcare systems is public-private partnerships (PPPs). This study elucidates the proposed key performance indicators initiated by the Ministry of Health of Saudi Arabia based on the projections of the government, known as Vision 2030, from the perspective of health risk factors. METHODS: Through an inductive content analysis, this study assessed primary and secondary data in relation to the Saudi National Transformation Program (NTP). To identify the institutions that played a role in formulating the new Saudi Healthcare System, health policies, regulations, and reports published between 1996 and 2016 were categorized. After ranking the risk factors, the investigator selected 13 healthcare professionals in four focus group interviews to insightfully explore the challenges that the NTP faces from a health risk perspective. Thus, the study employed qualitative data gathered through focus group interviews with key figures as well as data extracted from written sources to identify distinct but interrelated partnerships practiced within risk management. RESULTS: A methodological overview of NTP priority and implementation offered practical guidance in the healthcare context. The five critical factors in maintaining successful and sustainable PPPs were (1) trustworthiness, (2) technological capability, (3) patient-centeredness, (4) competence, and (5) flexibility. Concession on primary and secondary healthcare services might be a good option based on the literature review and considering its popularity in other countries. A high outcome-based risk of PPPs was found as the most commonly shared perspective in risk management. CONCLUSIONS: Although the impact of the NTP rise has yet to be explored, its potential for challenging health consequences requires consideration and substantial regulatory action. This study contributes to the emerging critical analysis on local health initiatives by highlighting how integration may only be possible with a more radical conceptualization of national health governance.

A descriptive cross-sectional survey was conducted over 5 months in two tertiary hospitals in Riyadh, Saudi Arabia. The 5-month period was from November 2014 to March 2015. The survey instrument used was a Short-Form Health Survey SF-36 (the RAND 36-item) questionnaire that measure QOL of the caregivers. Our study subjects included 289 randomly selected Saudi caregivers. Almost all the mean scores were increased (higher than 50) with the exception of levels of energy/fatigue. Role functioning/physical scored the highest (81.02 ± 35.33) followed by physical functioning (76.34 ± 29.83). Other domains of QOL scored (71.02 ± 35.33) for the role functioning/emotional; pain (71.15 ± 28.48), emotional well-being (60.58 ± 18.44); social functioning (58.39 ± 25.83), and general health (54.32 ± 17.08). In multivariate regression analysis, the model predicts that the contributions of age, gender, and the cancer type of patients were a statistically significant predictor with the QOL domains of caregivers. Cancer caregivers in Saudi Arabia caring for patients more than 1 year after diagnosis reported favorable QOL. Factors associated with QOL domains included age, gender of the caregivers, and the types of cancer patients. These findings are encouraging as a baseline for providing more information to future studies in QOL of caregivers.

This study aims to determine the factors that act as barriers to Saudi cancer patients in participating in a clinical trial (CT). A total of 244 patients from two different tertiary level hospitals (King Khalid University Hospital and King Fahad Medical City Hospital) in Riyadh, Saudi Arabia, participated in this cross-sectional study. The participants were interviewed by a trained researcher between September and November 2015. All respondents answered a three-part questionnaire which includes demographics, clinical information, and questions related to awareness of CTs, willingness to participate, and factors affecting participation in CTs. The mean age of the participants was 50.83, and 57 % of the participants were females. Most of the participants (63.5 %) were currently being treated for cancer, and 28 % were diagnosed with breast cancer followed by colorectal cancer. Health status or quality of life was self-reported as acceptable by 27.9 % of the participants, and 25 % of the participants at stage II of cancer. The factors that act as barriers to Saudi cancer patients in participating in a CT can be categorized into patient- and physician-related factors. Patient factors include lack of awareness, misconception and fear in participating in CTs; physician-related factors comprise of lack of encouragement from physician to patients in participating in a CT. The study identified few major barriers to participation in CTs. Increased patient awareness and recruitment strategies are required to increase accrual of patients including training for physicians and disseminating easy-to-read tools to the public.

BACKGROUND: Owing to a scarcity of data or other causes, patient research on the orphan population is lacking in most societies. Consequently, the primary goal of this study was to explore quality of life (QOL) and quality of care (QOC) among orphan patients (OPs) receiving tertiary healthcare services in Saudi Arabia (SA). METHOD: This study used a cross-sectional, quantitative survey design. Participants included 216 OPs either currently undergoing or who had undergone treatment for common chronic diseases (CDs) (e.g. cardiovascular disease, cancer, stroke and arthritis) during the past 12 months. The survey utilised the brief form from the World Health Organization Quality of Life (WHOQOL-BREF) tool and evaluated healthcare access and effectiveness domains to scrutinise the socio-medical patterns of OPs based on their current medical episodes. RESULTS: The descriptive analysis indicated that OPs' overall QOL reached a moderate level (M = 3.90). Similarly, participants reported relatively high levels of healthcare access and treatment effectiveness (M = 4.14 and M = 4.29, respectively). Stroke patients reported the highest QOL score (M = 3.95), and groups of patients with other CDs reported greater access to healthcare and more effective treatment maintenance compared to the other groups (M = 4.19 and M = 4.43, respectively). Regression analysis was conducted to predict overall QOL based on perceived QOC, and access explained only 6.5 % of the variance. An analysis of variance showed significant differences only between OPs with cardiovascular disease and cancer (P = .001), with the former reporting better access to tertiary healthcare services than the latter. CONCLUSIONS: Although some CD patients reported relatively acceptable levels of access to healthcare and receipt of effective treatment, the improvement of OPs' QOL and QOC poses a serious challenge for health policymakers.

AIM: To compare patients' assessment of quality of care provided by public tertiary hospitals grouped according to accreditation status. BACKGROUND: Healthcare institutions worldwide are increasingly adopting accreditation as continuing initiative aimed at improving structures, processes and outcomes associated with quality of care. Patients being recipients of health care need to participate in assessing the quality of care they experienced while confined for therapeutic management. DESIGN: Comparative, cross-sectional. METHOD: Data were collected from patients confined in public tertiary hospitals (n = 517 in four with accreditation and n = 542 in four without accreditation) in Riyadh, Saudi Arabia between February 2011-June 2011. Patients rated key performance indicators grouped under the dimensions of structure, process and outcome. Mann-Whitney U-test, Spearman Correlation Coefficient and coefficient of determination were used in analysing data. RESULTS: Patients in accredited public tertiary hospitals perceived structure, outcome and overall quality of care statistically higher than patients in non-accredited hospitals. No statistical differences were found in process (access and communication) indicators. Accreditation status is marginally associated with structure; outcome; and overall quality of care. The proportion of variance in the ranks of accreditation status explained the proportion of variance in the ranks of structure; outcome; and overall quality of care. CONCLUSION: The results apparently showed better structure, outcome and overall quality of care in accredited hospitals. Accreditation's association in the overall quality of care apparently remained unclear. Further studies are needed to appreciate the contribution of accreditation.

This study was conducted to assess the level of health awareness (HA) among students attending three undergraduate programs in the Colleges of Applied Medical Sciences (CAMS) in Riyadh, Saudi Arabia (SA). A modified self-reported survey was utilized to measure HA demonstrating four domains: Nutrition (NU), Personal Health (PH), Physical Exercise (PE), and Body Build (BB). The questionnaire was distributed to 302 female students attending the first semester of the academic year 2014-2015 BS degree in Radiology Sciences (RS), Clinical Laboratory (CL), and Health Education (HE) departments. Bloom's taxonomy was utilized to describe the three cognitive levels. Synthesizing, creating, and evaluating were grouped to represent high level indicators; applying cognitive skills only revealed an intermediate level; while memorizing and listing demonstrated low levels. In a 5-point Likert scale, the overall mean (M) of HA among CAMS students was 3.82 with the highest among students attending HE (M = 3.89). The domain of PH ranked first with a high average (M = 4.30). There were significant differences (α = 0.05), in the level of HA in PH and BB domains, among students in terms of program specialty only, but no such significant differences were found for other characteristics. The study recommended incorporating health promotion concepts within teaching curricula and conducting health and education campaigns by health education institutions.

Vandammella animalimorsus is a Gram-negative and non-motile bacterium typically transmitted to humans through direct contact with the saliva of infected animals, primarily through biting, scratches, or licks on fractured skin. The absence of a confirmed post-exposure treatment of V. animalimorsus bacterium highlights the imperative for developing an effective vaccine. We intended to determine potential vaccine candidates and paradigm a chimeric vaccine against V. animalimorsus by accessible public data analysis of the strain by utilizing reverse vaccinology. By subtractive genomics, five outer membranes were prioritized as potential vaccine candidates out of 2590 proteins. Based on the instability index and transmembrane helices, a multidrug transporter protein with locus ID A0A2A2AHJ4 was designated as a potential candidate for vaccine construct. Sixteen immunodominant epitopes were retrieved by utilizing the Immune Epitope Database. The epitope encodes the strong binding affinity, nonallergenic properties, non-toxicity, high antigenicity scores, and high solubility revealing the more appropriate vaccine construct. By utilizing appropriate linkers and adjuvants alongside a suitable adjuvant molecule, the epitopes were integrated into a chimeric vaccine to enhance immunogenicity, successfully eliciting both adaptive and innate immune responses. Moreover, the promising physicochemical features, the binding confirmation of the vaccine to the major innate immune receptor TLR-4, and molecular dynamics simulations of the designed vaccine have revealed the promising potential of the selected candidate. The integration of computational methods and omics data has demonstrated significant advantages in discovering novel vaccine targets and mitigating vaccine failure rates during clinical trials in recent years.
RESUMO
Autism spectrum disorder (ASD) is characterized by defects in social communication and interaction along with restricted interests and/or repetitive behavior. Children with ASD often also experience gastrointestinal (GI) problems in fact incidence of GI problems in ASD is estimated up to 80 percent. Intestinal microbiota, which is a collection of trillions of microorganisms both beneficial and potentially harmful bacteria living inside the gut, has been considered one of the key elements of gut disorders. The goal of this review is to explore potential link between gut microbiota and ASD in children, based on the recently available data. This review discusses recent advances in this rapidly expanding area of neurodevelopmental disorders, which focuses on what is known about the changes in composition of gut bacteria in children with ASD, exploration of possible mechanisms via which gut microbiota might influence the brain and thus lead to appearance of ASD symptoms, as well as potential treatments that involve modulation of gut flora to improve symptoms in children with ASD, i.e., probiotics, postbiotics or changes in the diet. Of course, it's important to keep in mind inherent difficulties in proving of existence of causal relationships between gut bacteria and ASD. There are significant gaps in understanding of the mechanism of gut-brain axis and the mechanisms that underlie ASD. Standardized approaches for research in this area are needed. This review would provide an overview of this exciting emerging field of research.

Purpose: This study aims to examine the influence of social media sites and television advertisements on compulsive shopping behavior, and whether this influence is mediated by materialism in the university students of Saudi Arabia. Methods: Data was collected from 487 students at Saudi universities. AMOS and Structural equation modeling (SEM) were utilized to examine the data. The research supports the Hypothesis that adolescents who are more materialistic are more prone than less materialistic adolescents to engage in compulsive shopping behavior. Results: The findings were consistent with other research, suggesting that the same remains true in the culture of Saudi Arabia. The research's findings show that television advertisements and the use of social media sites positively related to compulsive shopping behavior among university students, and materialism mediated the relationship between television advertisements and social media sites. Conclusion: The research emphasizes the significance of comprehending the materialistic attitude and consumption choices of adolescents and offers crucial information for scholars, decision-makers, and management of top companies.
RESUMO
The healthcare sector faces several challenges, such as rising costs, rising demand, and the need for sustainability. A new area of healthcare has emerged due to these problems, focusing on long-term improvements in management, social policy, and health economics. This research explores the cutting edge of healthcare, concentrating on long-term advancements in management, social policy, and health economics. To better understand the problems affecting the healthcare sector and to pinpoint the areas where sustainable solutions are most required, a survey of 2000 healthcare professionals and policymakers was performed. The data were analyzed using structural equation modeling (SEM), and a thorough sustainable healthcare model was created. According to the survey's findings, the healthcare sector now faces three significant challenges: growing prices, increased demand, and the need for sustainability. According to the respondents, the three main areas where sustainable innovations are most required are management, social policy, and health economics. These conclusions were supported by the (SEM) analysis, which also showed that sustainable practices in these fields significantly impact the sustainability of the healthcare system. These findings lead this research to conclude that to guarantee the accessibility and affordability of healthcare for everyone, a move towards sustainable practices in health economics, social policy, and management is needed. Cooperation between healthcare providers, policymakers, and other stakeholders is required to create creative solutions that support sustainability in the healthcare sector. This study offers a thorough framework for sustainable healthcare that may act as a guide for further research and the formulation of new regulations.
RESUMO
Neisseria meningitidis, commonly known as the meningococcus, leads to substantial illness and death among children and young adults globally, revealing as either epidemic or sporadic meningitis and/or septicemia. In this study, we have designed a novel peptide-based chimeric vaccine candidate against the N. meningitidis strain 331,401 serogroup X. Through rigorous analysis of subtractive genomics, two essential cytoplasmic proteins, namely UPI000012E8E0(UDP-3-O-acyl-GlcNAc deacetylase) and UPI0000ECF4A9(UDP-N-acetylglucosamine acyltransferase) emerged as potential drug targets. Additionally, using reverse vaccinology, the outer membrane protein UPI0001F4D537 (Membrane fusion protein MtrC) identified by subcellular localization and recognized for its known indispensable role in bacterial survival was identified as a novel chimeric vaccine target. Following a careful comparison of MHC-I, MHC-II, T-cell, and B-cell epitopes, three epitopes derived from UPI0001F4D537 were linked with three types of linkers-GGGS, EAAAK, and the essential PADRE-for vaccine construction. This resulted in eight distinct vaccine models (V1-V8). Among them V1 model was selected as the final vaccine construct. It exhibits exceptional immunogenicity, safety, and enhanced antigenicity, with 97.7 % of its residues in the Ramachandran plot's most favored region. Subsequently, the vaccine structure was docked with the TLR4/MD2 complex and six different HLA allele receptors using the HADDOCK server. The docking resulted in the lowest HADDOCK score of 39.3 ± 9.0 for TLR/MD2. Immune stimulation showed a strong immune response, including antibodies creation and the activation of B-cells, T Cytotoxic cells, T Helper cells, Natural Killer cells, and interleukins. Furthermore, the vaccine construct was successfully expressed in the Escherichia coli system by reverse transcription, optimization, and ligation in the pET-28a (+) vector for the expression study. The current study proposes V1 construct has the potential to elicit both cellular and humoral responses, crucial for the developing an epitope-based vaccine against N. meningitidis strain 331,401 serogroup X.

Introduction: Recently, the Saudi government has proposed several initiatives to promote mental health, including the national program named Wazen. The objective of this study was to observe the performance of mental hospitals using a balanced scorecard through this federal program. Methods: Secondary quantitative analysis was implemented utilizing the Wazen report program data in 2022. The report adopted a balanced scorecard (BSC) concept. The study focused on 19 mental health facilities (Eraddah Hospitals) in the Ministry of Health (MOH) regions. The MOH's annual statistical report for 2018 and 2022 was reviewed to explore more about beds, staff, and the number of new mental disorder cases. Data were analyzed using Microsoft Excel 365 and the Statistical Package for Social Sciences (SPSS Version 25) software. Mental health hospitals were classified into three categories. Results: Most rural hospitals had lower performance in the yellow threshold value that might need improvement. The data shows that the mean of all hospital performance in some domains ranged, yielding 70% staff engagement and 77% continued educational activity, indicating unsatisfactory performance across public mental health services. The means score of access to care was 97.0% and 94.7%, marking the better mental health services provided. Between 2018 and 2022, there was a significant rise in the prevalence of mental disorders, as evidenced by the number of new patients and outpatients indicated by specific mental diseases, including conditions of psychological development (F80-F98). Discussion: The high quality of mental healthcare is manifested by therapeutic ethos with a high degree of interaction between professional careers and service users. The former is enhanced by highly educated, competent, compassionate, self-aware, and specialized healthcare professionals in mental health. When assessing mental healthcare services, we recommend considering providers' and professionals' conditions for successful implementation in alignment with patient experience.
RESUMO
Rapid urban developmental growth is a heated debate worldwide due to environmental challenges. This research has examined the spatiotemporal trend of informal built-up growth in Karachi city. Using a geo-information system, the past twenty years (2000-2020) trends of informal built-up growth are examined. For attaining the research objectives, geo-referenced high-resolution maps and satellite images are used for accuracy based spatial data. Karachi is divided into five different land use and land cover (LULC): formal built-up, informal built-up, vacant, water bodies, and green spaces. Spatial data of informal built-up growth change of five different years, 2000, 2005, 2010, 2015, and 2020 are generated through acquired maps digitization using ArcMap. Subsequently, the gains and transfers of Karachi's informal built-up growth based on five years 2000-2005, 2005-2010, 2010-2015, and 2015-2020 are analyzed using the Land Change Modeler (LCM) in IDRISI software. Also, land use land cover changes (LULCC) are predicted for the next 40 years (2020-2060) using the integrated Cellular Automata Markov (CA-Markov) simulation model in IDRISI. The results revealed that Karachi's built-up is expanding rapidly. Land conversion into the informal built-up area is alarming, as it has changed from 144.31 km2 to 217.19 km2 with 72.88 km2 in the past twenty years (2000-2020) and has occupied green and agricultural land. Most informal built-up areas have transitioned from vacant (71.01 km2) land use land cover (LULC). The informal built-up area could expand from 217.19 km2 to 317.63 km2, with about 100.44 km2 up to 2060. The planned and unplanned development will be towards the city's East (E) direction and will convert and ruin agriculture and vacant land. The present study provides suggestions to urban planners, administrative authorities, and policymakers to control informal growth and achieve sustainable development goals in developing countries.
