First, this study examined the relationships of work alienation with explorative learning and exploitative learning. Second, the study tested the role of emotional exhaustion as a mediator of the relationships of work alienation with explorative learning and exploitative learning. Job Demands-Resources model was used as the underlying theoretical foundation to establish these relationships.Methods: Two-source time-lagged data were collected from 225 middle-level managers and their 222 immediate supervisors in 87 Pakistani firms spanning different industries. Structural equation modeling and bootstrapping were used to test the hypothesized relationships,.Results: The study revealed that work alienation is negatively related to both explorative learning and exploitative learning. Moreover, the study also established emotional exhaustion as a mechanism underlying the relationships work alienation with explorative learning and exploitative learning by showing that work alienation enhances emotional exhaustion, which, in turn, negatively influences both explorative learning and exploitative learning.Conclusion: By conceptualizing and providing empirical evidence of the negative relationships of work alienation with explorative learning and exploitative learning, both directly and via emotional exhaustion, the study signified some of the important but largely ignored dynamics of the employment relationship within the current regime of organizational structures. The findings suggest that the managers’ sensed estrangement from work and work context need to be addressed, as it can exhaust them emotionally and hinder their search and acquisition of new knowledge and competencies.Keywords: work alienation, emotional exhaustion, explorative learning, exploitative learning, Job Demands-Resources model

Muhammad Aamir Shafique Khan,1 Du Jianguo,1 Ahmed Abdul Hameed,2 Tehseen UL Mushtaq,2 Muhammad Usman2 1School of Management, Jiangsu University, Zhenjiang, People’s Republic of China; 2Department of Management Sciences, COMSATS University Islamabad, Lahore, Pakistan Purpose: The purpose of the present study is twofold. First, we examined the relationship between workplace romance and employee job performance and tested the role of affective commitment foci – namely, affective coworker commitment, affective supervisor commitment, and affective organizational commitment – as parallel mediators in the relationship between workplace romance and employee job performance. Second, we tested the moderating role of culture on the interrelationships between workplace romance, affective commitment foci, and employee job performance. Methods: A two-wave (3-month interval) survey data were collected from 312 paramedics – 162 and 150 from Pakistani and Chinese public-sector hospitals, respectively. The first and second waves of data collection took place in January and May 2017, respectively. Structural equation modeling (SEM), bootstrapping technique, and multigroup analysis were used to test the interrelationships between workplace romance, affective commitment foci, and employee job performance and to examine the cross-cultural differences in these interrelations. Results: Results obtained using SEM show that workplace romance positively influences employee performance. Importantly, the study revealed that the three foci of affective commitment – namely, coworker affective commitment, supervisor affective commitment, and organizational affective commitment – as parallel mediators fully mediate the relationship between workplace romance and employee performance. Moreover, national culture moderates the indirect relationship between workplace romance and employee job performance, where workplace romance is stronger for the Chinese data sample. Conclusion: It is concluded that workplace romance is positively related to employee job performance and that affective commitment foci fully mediate the positive relationship between workplace romance and employee job performance. Moreover, culture moderates the indirect relationship between workplace romance and employee job performance. The study contributes to theory and practice by studying an essential but largely ignored aspect of the workplace and portraying it as a constructive influence on employee job performance and their affective commitment to coworkers, supervisor, and organization.

BackgroundThere is a documented need to build capacity for theory- and evidence-informed knowledge translation (KT) and patient engagement (PE) practice in health research. Dissemination of foundational content online coupled with social media promotion may build capacity by increasing awareness, knowledge, and positive attitudes. ObjectiveThis retrospective study sought to (1) describe exposure and engagement of the KnowledgeNudge KT and PE dissemination strategy (online blog and Twitter profile) over 2 years and (2) identify and compare characteristics of individual posts with the most and least exposure and reach. MethodsExposure was assessed by blog site views per month and Twitter profile impressions per month. Engagement was assessed by Twitter profile interactions per month. Descriptive statistics were calculated for 6-month blocks and compared using one-way analysis of variance or Student t test. Individual post exposure was assessed by average post views per week. Individual post reach was assessed by average post reads per week. High- and low-profile blog posts with the highest and lowest 10th percentile for exposure and reach were identified. ResultsA total of 99 posts and 755 tweets were published during the study period. There was a significant increase in exposure (P=.004) and reach (P

Environmental pollution from metal toxicity is a widespread concern. Certain bacteria hold promise for bioremediation via the conversion of toxic chromium compounds into less harmful forms, promoting environmental cleanup. In this study, we report the isolation and detailed characterization of a highly chromium-tolerant bacterium, Bacillus tropicus CRB14. The isolate is capable of growing on 5000 mg/L Cr (VI) in an LB (Luria Bertani) agar plate while on 900 mg/L Cr (VI) in LB broth. It shows an 86.57% reduction ability in 96 h of culture. It can also tolerate high levels of As, Cd, Co, Fe, Zn, and Pb. The isolate also shows plant growth-promoting potential as demonstrated by a significant activity of nitrogen fixation, phosphate solubilization, IAA (indole acetic acid), and siderophore production. Whole-genome sequencing revealed that the isolate lacks Cr resistance genes in their plasmids and are located on its chromosome. The presence of the chrA gene points towards Cr(VI) transport, while the absence of ycnD suggests alternative reduction pathways. The genome harbors features like genomic islands and CRISPR-Cas systems, potentially aiding adaptation and defense. Analysis suggests robust metabolic pathways, potentially involved in Cr detoxification. Notably, genes for siderophore and NRP-metallophore production were identified. Whole-genome sequencing data also provides the basis for molecular validation of various genes. Findings from this study highlight the potential application of Bacillus tropicus CRB14 for bioremediation while plant growth promotion can be utilized as an added benefit.

Background: COVID-19 has been linked to hyperglycemia and diabetes, with noteworthy variation in outcomes. This study aimed to compare the sociodemographic factors, clinical characteristics, and in-hospital and short-term post-discharge outcomes between COVID-19 patients with new onset hyperglycemia and pre-existing diabetes patients in tertiary care hospitals in Bangladesh., Methods: A prospective observational study was conducted among adult COVID-19 patients with new onset hyperglycemia or pre-existing diabetes admitted to the COVID-19 unit of Dhaka Medical College Hospital between April 2021 and October 2021. Patients were conveniently selected from indoors. Bivariate analysis was used to compare sociodemographic and clinical characteristics at admission and short-term outcomes. The Cox proportional hazard model was used to examine factors associated with time to death in the hospital. All statistical analyses were performed using Stata Version 17., Results: A total of 169 patients were included. Of these, 29 died in the hospital, and four left against medical advice. Out of the 136 survivors, 135 came for follow-up two weeks after discharge. At baseline, 30.18% of patients had new onset hyperglycemia, and 69.8% had pre-existing diabetes. The average age of patients was 56.38 ± 14.21 years, and 60.36% were male. A significantly higher proportion of COVID-19 patients with new onset hyperglycemia were smokers than those with pre-existing diabetes (p = 0.003). However, pre-existing diabetes was associated with higher lung involvement (p = 0.047) and comorbidities (p = 0.002). Age, income over 35,000 BDT (USD 335.5$), and a BMI over 25 kg/m2 emerged as significant predictors of prolonged hospital stay and mortality. Post-discharge follow-up indicated that new-onset hyperglycemia resolved in 8.89% of patients, whereas 19.26% continued to exhibit hyperglycemia, with smoking being a significant determinant of its persistence (p = 0.001)., Conclusion: In conclusion, our investigation illuminates the clinical trajectory of new-onset hyperglycemia in the context of COVID-19 and reinforces the necessity for diligent monitoring and management post-discharge. Therefore, close monitoring and follow-up of COVID-19 patients is recommended for the early detection and management of hyperglycemia and the prevention of diabetes development in the long run., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Sultana Kakoly et al.

Objective: The study aimed to assess health-seeking behaviour (HSB) and associated factors among hypertensive patients in Bangladesh. Methods: This cross-sectional study was conducted in the Hypertension & Research Centre, Rangpur, Bangladesh, between January 2022 and June 2022. A total of 497 hypertensive adults were recruited consecutively. A pre-tested structured questionnaire was deployed by the research team for data collection. Multivariable logistic regression analysis was used to explore the predictors of HSB. Results: The mean age of the hypertensive patients was 52 ± 11 (SD) years. Most of them were aged between 51 and 60 years (33%), female (55%), came from rural areas (57%), and belonged to middle socioeconomic class (68%). One-fourth of the patients (27%) had chosen informal healthcare providers for their first consultation. Fear of stroke (244, 45%), headache (170, 36%), and neck pain (81, 17%) were the three most common compelling causes of their visit to the hypertension centre. Age (aOR 0.78, 95% CI 0.68 - 0.89), male sex (aOR: 1.79, 95% CI 1.05 - 3.10), living in semi-urban (aOR 4.68, 95% CI 1.45 - 15.10) and rural area (aOR 1.68, 95% CI 1.01 - 2.80), farmers as occupation (aOR: 3.24, 95%CI: 1.31 - 8.06) and belonging to lower social economic class (aOR 4.24, 95% CI 1.68 - 10.69) were predictors of visiting informal providers of hypertensive patient. One-fourth of the hypertensive patients received consultation from informal healthcare providers. Conclusions: Raising awareness among patients and proper referral to specialised hypertension centres could promulgate the patients towards appropriate behaviour.

Background: To align with the 2030 vision of the World Health Organization (WHO) to ensure 90% of girls receive the HPV vaccine before turning 15, Bangladesh has recently started the (HPV) vaccine campaign nationwide. Therefore, our study aimed to assess the level of its acceptance among parents of eligible daughters in Bangladesh., Methods: This nationwide cross-sectional study was conducted among the self-identified parents of daughters in the age group of 9-15 years between June 28 and August 2, 2023. A total of 2,151 parents were conveniently selected from all eight divisions of Bangladesh. Data was collected through face-to-face interviews using a semi-structured questionnaire. The Health Belief Model was used to appraise respondents' beliefs concerning HPV and its vaccination. Adjusted odds ratios (AOR) with a corresponding 95% confidence interval (CI), and a p-value of <0.05 was considered statistically significant. R Studio (Version 2023.09.0+463) was used as an interface for data analysis, while R (the programming language) was used for statistical computations., Results: The mean age of the study participants was 38.18 (±5.86) years. The overall acceptance rate of the HPV vaccine was 86.61% (95%CI: 85.09-88.02). The vaccine acceptance level was positively associated with all the domains of the HBM (p<0.001), except in the perceived barrier domain (p = 0.489). After adjustment for other factors, it was found that higher age was associated with a decreased acceptance (AOR: 0.92; 95% CI: 0.89-0.95). The urban residents exhibited 42% lower odds of vaccine acceptance than rural (AOR: 0.58; 95% CI: 0.36-0.92). Similarly, participants of the middle-income group had 44% lower odds than the lower-income group (AOR: 0.56; 95% CI: 0.32-0.97)., Conclusion: Our study found a reasonably good level of acceptance of the HPV vaccine among the parents of eligible daughters. Multiple factors such as younger age, urban residence, belonging to the middle income group, history of regular routine health check-ups, knowledge of cervical cancer, positive perception about benefits of the vaccine, and positive cues to actions were associated with HPV vaccine acceptance., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Hawlader et al.

Chest X-ray is an important diagnostic aid frequently used alongside microscopic smear of sputum for the confirmation of pulmonary tuberculosis (TB). However, there is a dearth of literature investigating the clinical and radiological pattern of sputum positive pulmonary TB among adults in Bangladesh. The current study explored these patterns in presentation. This descriptive cross-sectional study was conducted at outpatients in department of medicine of a tertiary care hospital. A total of 50 newly diagnosed adult cases of smear positive pulmonary TB attending at the Directly Observed Treatment Short-course (DOTS) corners were consecutively included. Informed written consent was taken before inclusion. Data were collected through face-to-face interview. Radiological presentation was explored using chest X-ray. Data were analyzed by SPSS version 26.0. The average age of patients was 41.0±17.12 years and majority were male (78.0%). The most prevalent respiratory symptom was cough (80.0%) followed by constitutional symptom like fever (70.0%) and weight loss (72.0%). Wasting was the predominant sign (60.0%). Radiologically both lungs were involved in 32.0%, left lung were involved in 30.0% cases and right lung were involved in 26.0% of cases. Twelve percent (12.0%) of patients had normal chest X-ray. Upper zone involvement was commonly observed in this study's patients (66.0%). The predominant pattern was consolidation (46.0%) followed by fibrosis (26.0%), nodular opacity (12.0%), collapse (10.0%), cavity (6.0%), pleural effusion (2.0%) and bronchiectasis (2.0%). Findings of this study would help familiarize and identify the common clinical and radiological presentations of sputum positive pulmonary TB patients in day-to-day practice.

Alzheimer's disease (AD) is an age-dependent neurodegenerative disease characterized by extracellular Amyloid Aβ peptide (Aβ) deposition and intracellular Tau protein aggregation. Glia, especially microglia and astrocytes are core participants during the progression of AD and these cells are the mediators of Aβ clearance and degradation. The microbiota-gut-brain axis (MGBA) is a complex interactive network between the gut and brain involved in neurodegeneration. MGBA affects the function of glia in the central nervous system (CNS), and microbial metabolites regulate the communication between astrocytes and microglia; however, whether such communication is part of AD pathophysiology remains unknown. One of the potential links in bilateral gut-brain communication is tryptophan (Trp) metabolism. The microbiota-originated Trp and its metabolites enter the CNS to control microglial activation, and the activated microglia subsequently affect astrocyte functions. The present review highlights the role of MGBA in AD pathology, especially the roles of Trp per se and its metabolism as a part of the gut microbiota and brain communications. We (i) discuss the roles of Trp derivatives in microglia-astrocyte crosstalk from a bioinformatics perspective, (ii) describe the role of glia polarization in the microglia-astrocyte crosstalk and AD pathology, and (iii) summarize the potential of Trp metabolism as a therapeutic target. Finally, we review the role of Trp in AD from the perspective of the gut-brain axis and microglia, as well as astrocyte crosstalk, to inspire the discovery of novel AD therapeutics.

The rising frequency of multidrug-resistant (MDR) Acinetobacter baumannii infections represents a significant public health challenge in Bangladesh. Genomic analysis of bacterial pathogens enhances surveillance and control efforts by providing insights into genetic diversity, antimicrobial resistance (AMR) profiles, and transmission dynamics. In this study, we conducted a comprehensive bioinformatic analysis of 82 whole-genome sequences (WGS) of A. baumannii from Bangladesh to understand their genomic epidemiological characteristics. WGS of the MDR and biofilm-forming A. baumannii strain S1C revealed the presence of 28 AMR genes, predicting its pathogenicity and classification within sequence type ST2. Multi-locus sequence typing (MLST) genotyping suggested heterogeneity in the distribution of clinical A. baumannii strains in Bangladesh, with a predominance of ST575. The resistome diversity was evident from the detection of 82 different AMR genes, with antibiotic inactivation being the most prevalent resistance mechanism. All strains were predicted to be multidrug-resistant. The observed virulence genes were associated with immune evasion, biofilm formation, adherence, nutrient acquisition, effector delivery, and other mechanisms. Mobile genetic elements carrying AMR genes were predicted in 68.29% (N = 56) of the genomes. The "open" state of the pan-genome and a high proportion of accessory genes highlighted the genome plasticity and diversity of A. baumannii in Bangladesh. Additionally, phylogenomic analysis indicated clustering of A. baumannii strains into three separate clades according to sequence type. In summary, our findings offer detailed insights into the genomic landscape of A. baumannii in Bangladesh, contributing to our understanding of its epidemiology and pathogenicity and informing strategies to combat this pathogen., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2024 The Authors.
