Efficacy and safety of laparoscopic Heller's myotomy versus pneumatic dilatation for achalasia: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND AND OBJECTIVES: Achalasia has several treatment modalities. We aim to compare the efficacy and safety of laparoscopic Heller myotomy (LHM) with those of pneumatic dilatation (PD) in adult patients suffering from achalasia. METHODS: We searched Cochrane CENTRAL, PubMed, Web of Science, SCOPUS and Embase for related clinical trials about patients suffering from achalasia. The quality appraisal and assessment of risk of bias were conducted with GRADE and Cochrane's risk of bias tool, respectively. Homogeneous and heterogeneous data was analyzed under fixed and random-effects models, respectively. RESULTS: The pooled analysis of 10 studies showed that PD was associated with a higher rate of remission at three months, one year, three years and five years (RR = 1.25 [1.09, 1.42] (p = 0.001); RR = 1.13 [1.05, 1.20] (p = 0.0004); RR = 1.48 [1.19, 1.82] (p = 0.0003); RR = 1.49 [1.18, 1.89] (p = 0.001)), respectively. LHM was associated with lower number of cases suffering from adverse events, dysphagia and relapses (RR = 0.50 [0.25, 0.98] (p = 0.04); RR = 0.33 [0.16, 0.71] (p = 0.004); RR = 0.38 [0.15, 0.97] (p = 0.04)), respectively. There is no significant difference between both groups regarding the lower esophageal pressure, perforations, remission rate at two years, Eckardt score after one year and reflux. CONCLUSION: PD had higher remission rates than LHM at three months, one year and three years, but not at two years or five years. More research is needed to determine whether PD has a significant advantage over LHM in terms of long-term remission rates.

Efficacy and safety of terlipressin and albumin vs. noradrenaline and albumin in adult patients with hepatorenal syndrome: A systematic review and meta-analysis.

INTRODUCTION AND OBJECTIVES: Hepatorenal syndrome (HRS) is a serious complication of cirrhosis treated with various medications. We aim to evaluate terlipressin and albumin's effectiveness and safety compared to albumin and noradrenaline in adult hepatorenal disease patients. MATERIALS AND METHODS: Clinical trials from four databases were included. Cochrane's approach for calculating bias risk was utilized. We rated the quality evaluation by Grading of Recommendations Assessment, Development, and Evaluation (GRADE). We included the following outcomes: serum creatinine (mg/dl), urine output (ml/24 h), mean arterial pressure (mmHg), reversal rate of HRS, mortality rate, blood plasma renin activity (ng/ml/h), plasma aldosterone concentration (pg/ml), urine sodium (mEq/l), and creatinine clearance (ml/min). RESULTS: Our analysis of nine clinical studies revealed that the noradrenaline group was associated with higher creatinine clearance (MD = 4.22 [0.40, 8.05]), (P = 0.03). There were no significant differences in serum creatinine levels (MD = 0.03 [-0.07, 0.13]), urinary sodium (MD = -1.02 [-5.15, 3.11]), urine output (MD = 32.75 [-93.94, 159.44]), mean arterial pressure (MD = 1.40 [-1.17, 3.96]), plasma renin activity (MD = 1.35 [-0.17, 2.87]), plasma aldosterone concentration (MD = 55.35 [-24.59, 135.29]), reversal rate of HRS (RR = 1.15 [0.96, 1.37]), or mortality rate (RR = 0.87 [0.74, 1.01]) between the two groups (p-values > 0.05). CONCLUSIONS: Noradrenaline is a safe alternative medical therapy for HRS.

Gold nanoparticle-based selective and efficient spectrophotometric assay for the insecticide methamidophos.

A reliable, rapid, and inexpensive nano-sized chemosensor is presented for methamidophos (MET) - an insecticide. Poly(lactic acid) (PLA)-stabilized gold nanoparticles (AuNPs) were synthesized by a simple one-pot, two-phase chemical reduction method. The synthesized PLA-AuNPs were subsequently employed for selective, efficient, and quantitative detection of MET. MET is one of the highly toxic pesticides used for eradication of agricultural and urban insects. Upon the addition of MET, the wine-red color of PLA-AuNPs swiftly transformed into greyish-blue, further corroborated by a significant bathochromic and hyperchromic shift in the SPR band. The presence of other interfering insecticides, metal salts, and drugs did not have any pronounced effect on quantitative MET detection. The detection limit, the quantification limit, and linear dynamic range of MET utilizing PLA-AuNPs were  0.0027 µM, 0.005 µM, and 0.005-1000 µM, respectively. The PLA-AuNP-based assay renders an efficient, rapid, accurate, and selective quantification of MET in food, biological, and environmental samples. The proposed sensor provides an appropriate platform for fast and on-the-spot determination of MET without requiring a well-equipped lab setup.

Development of low-cost and high-efficiency solar modules based on perovskite solar cells for large-scale applications.

Solar energy has emerged as a viable and competitive renewable resource due to its abundance and cost-effectiveness. To meet the global energy demands, there is a growing need for efficient devices with unique compositions. In this study, we designed and analyzed a perovskite solar cell (PSC) incorporating methylammonium tin iodide (CH3NH3SnI3) as the active optical absorber material, tin iodide (SnO2) as the electron transport layer (ETL), and copper thiocyanate (CuSCN) as the hole transport layer (HTL) using SCAPS-1D software for numerical investigations. Subsequently, the optimized outcomes were implemented in the PVSyst software package to derive the characteristics of a solar module based on the proposed novel solar cell composition. The objective of our research was to enhance the stability of solar cell for use in solar module. This was achieved by optimizing the thicknesses of the compositional layers which resulted in the enhancement of excess electron and hole mobilities and a reduction in defect densities, thereby leading to an improvement in the device performance. The optimization of excess electron and hole mobilities, as well as defect densities, was conducted to improve the device performance. SCAPS calculations indicated that the perovskite absorber layer (CH3NH3SnI3) may achieve the best possible performance with a maximum optimized thickness of 3.2 µm. The optimized thickness value for CuSCN-HTL and SnO2-ETL were found to be 0.07 µm and 0.05 µm respectively resulting in a maximum power conversion efficiency (PCE) of 23.57%. Variations in open circuit voltage (Voc), short circuit current (Jsc), fill factor (FF %), and quantum efficiency (QE) associated with the optimized thickness values of all layers in the ITO/SnO2/CH3NH3SnI3/CuSCN/Mo composition were critically analyzed. The use of these input parameters resulted in power creation of 557.4 W for a module consisting of 72 cells with an annual performance ratio of 80.3%. These recent investigations are expected to be effective in the design and fabrication of eco-friendly and high-performance solar cells in terms of efficiency.

Technostress, Quality of Work Life, and Job Performance: A Moderated Mediation Model.

This study examines the effect of technostress on teachers' quality of work life and job performance. A moderated mediation model is proposed and tested based on the transactional model of stress and coping. This study proposes organizational flexibility as the boundary condition-a first-level moderator-and quality of work life as the explanatory variable. A sample of 199 university teachers who worked from home or used the hybrid teaching mode was selected. Data were collected through closed-ended questionnaires. Structural equation modeling (SEM) and the Hayes PROCESS Macro (extension in SPSS) were used for hypothesis testing. The results found that the three dimensions of technostress (Techno complexity, Techno invasion, and Techno overload) negatively and significantly affect teachers' quality of work life. However, there are significant positive direct effects of these three dimensions of technostress on employee performance and significant negative indirect effects on performance through quality of work life. Organizational flexibility acts as a significant moderator, where a low value of organizational flexibility enhances the negative relationship between technostress and quality of work life. In contrast, high values of organizational flexibility convert the significant negative relationship into an insignificant impact. The university management must take measures to overcome technostress among teachers by showing flexibility.

Enhancement in photocatalytic selectivity of TiO2-based nano-catalyst through molecular imprinting technology.

Improvement in the photocatalytic selectivity is imperative for the effective and efficient utilization of catalysts. In this study, a molecularly imprinted polymer-coated iron-doped titanium dioxide (Fe-TiO2@MIP) nanocomposite was successfully synthesized by precipitation polymerization while using RB-19 as a template. The synthesized nanocomposites (Fe-TiO2@MIP and Fe-TiO2@NIP) were characterized by Fourier transform infrared spectroscopy (FT-IR), atomic force microscopy (AFM), field emission scanning electron microscopy (FESEM) with energy dispersive X-ray (EDX), X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Brunauer-EMMETT-Teller (BET), and UV-visible spectrophotometry. The optimized binding experiments revealed a high imprinting factor of 5.0 for RB-19. The catalytic degradation efficiency and selectivity of Fe-TiO2@MIP enhanced to almost complete degradation of RB-19 from 70% for the parent Fe-TiO2 and 76% for Fe-TiO2@NIP. An outstanding degradation selectivity of RB-19 was achieved compared to other competitive dyes. Finally, the analysis of the non-degraded and degraded RB-19 by ESI-MS revealed the presence of different intermediates that fits well with the proposed degradation mechanism. The study opens new possibilities of selective photo-degradation of targeted contaminants that may ultimately lead to efficient use of photocatalysts.

Evaluation of the effect of probiotics on septic complications in patients with severe acute pancreatitis. A systematic review and meta-analysis.

Introduction: Severe acute pancreatitis (SAP) with major complications such as necrosis and multiple organ dysfunction syndrome (MODS) often leads to high mortality rates despite intensive treatment. Aim: To evaluate the effect of symbiotics (probiotics) on septic complications in patients with SAP. Material and methods: We searched the PubMed, Cochrane CENTRAL, SCOPUS, and Web of Science databases for relevant clinical trials and excluded observational studies. Quality appraisal was evaluated according to GRADE, and we assessed the risk of bias using Cochrane's risk of bias tool. We included the following outcomes: C-reactive protein (CRP), APACHE II score, hospital stay, multiorgan failure (MOF), systemic inflammatory response syndrome, infected pancreatic necrosis, septicaemia, need for operation, and death. We performed the analysis of homogeneous data under a fixed-effects model, while analysis of heterogeneous data were analysed under a random-effects model. We performed the analysis of dichotomous outcomes using the risk ratio (RR) and relative 95% confidence interval (CI). Results: We included a total of 7 clinical trials. We found that there was no significant difference between both groups regarding MOF (RR = 0.60 (0.25, 1.44), p = 0.26), septicaemia (RR = 0.66 (0.29, 1.50), p = 0.32), death (RR = 0.66 (0.19, 2.26), p = 0.51), infected pancreatic necrosis (RR = 0.50 (0.18, 1.38), p = 0.18), SIRS (RR = 0.81 (0.29, 2.23), p = 0.68), CRP, APACHE II score, and hospital stay. Conclusions: Contrary to some published trials, our meta-analysis concludes that the use of probiotics in patients with SAP is not effective in reducing the mortality rate, septic complications, and need for operation.

Novel epoxy-terminated macromonomers and their polymerization for synthesis of bottle-brush type amphiphilic block copolymers.

Architecture of polymers has vital implications for their physical properties and applications. In this study, synthesis of a series of novel epoxy-terminated macromonomers namely Ep-DEGMME, Ep-TEGMME, Ep-EGMEE, Ep-EGMBE, and Ep-EGMHE is reported. The synthesized macromonomers vary in number of ethylene oxide units and length of the alkyl group. These macromonomers are first homopolymerized by anionic ring-opening polymerization for synthesis of homopolymers of a molar mass range. Subsequently, these macromonomers with different lengths of two segments (alkyl group and ethylene oxide units) are copolymerized with other monomers for synthesis of bottle-brush type architectures. In the first case, di- and tri-block copolymers of Ep-EGMBE are synthesized while using MeO-PEG or PEG as a macroinitiator; the resulting block copolymers have hydrophilic handle and hydrophobic brush. On the same lines, block copolymers of Ep-TEGMME with ε-caprolactone have hydrophobic handle and hydrophilic brush. The synthesized block copolymers are comprehensively characterized by SEC and liquid chromatography at critical conditions. The analysis reveals the successful synthesis of block copolymers while providing information on relative total molar mass, and individual block lengths of the block copolymers, along with amount of unwanted homopolymers in the sample.

Efficacy of endoscopic trans-papillary gallbladder stenting and drainage in acute calculous cholecystitis in high-risk patients: a systematic review and meta-analysis.

Background and aims: Acute calculous cholecystitis (ACC) represents about one-third of all surgical emergencies. The gold standard management of ACC is laparoscopic cholecystectomy. Although cholecystectomy is a safe procedure, it may be dangerous and contraindicated in patients with complex comorbidities. Endoscopic transpapillary gallbladder stenting (ETGBS) and drainage had been widely used to manage patients suffering from ACC with comorbidities. Methods: We searched PubMed, SCOPUS, Web of Science, and Cochrane Library for relevant studies assessing the use of ETGBS in patients suffering from ACC with various comorbidities. Risk of bias assessment was performed using the National Institues of Health (NIH) tool. We included the following outcomes: clinical success, technical success, late complications, and pancreatitis. Results: We included seven studies that met our inclusion criteria. We found that the pooled proportion of clinical success, technical success, late complications, and pancreatitis was [91.3%, 95% confidence interval (CI) (86.8%, 95.9%)], [92.8%, 95% CI (89%, 96.5%)], [5.4%, 95% CI (2.9%, 7.9%)], and [3.5%, 95% CI (1.2%, 5.8%)], respectively. Conclusion: We found that an ETGBS was an effective and well-tolerated method for the treatment of cholecystitis, especially in high-risk individuals.

Fecal Microbiota Transplantation in Human Immunodeficiency Virus-Infected Patient Population: A Systematic Review and Meta-Analysis.

Background: Patients with human immunodeficiency virus (HIV) infection suffer from alterations in gut microbiota due to recurrent gastrointestinal infections and systemic inflammation. Fecal microbiota transplantation (FMT) appears to be a potential therapy; however, there are concerns about its safety. Likewise, no previous meta-analysis evaluated FMT efficacy in HIV-infected patients. Methods: We conducted a thorough electronic search on PubMed, Scopus, OVID, Web of Science, and Cochrane CENTRAL for clinical studies assessing the safety and efficacy of FMT in patients with HIV and gastrointestinal dysbiosis, where FMT was indicated to restore the disrupted microbiota. Results: FMT significantly restored the typical microbiome in patients with Clostridium difficile (C. difficile) and non-C. difficile and reduced the risk of gastrointestinal infections in HIV patients receiving antiretroviral therapy (odds ratio (OR) = 0.774, 95% confidence interval (CI): (0.62, 0.966)). Furthermore, adverse events, such as distention and bloating, associated with FMT were comparable between HIV and health controls (OR = 0.60, 95% CI: (0.07, 4.6)), with no statistical difference. Conclusions: Current evidence demonstrated that FMT is safe and effective in HIV patients suffering from alterations in gut microbiota. We recommend further multi-centric clinical studies to address the optimal transplant amount and source for FMT. To the best of our knowledge, this is the first meta-analysis to assess the safety and efficacy of FMT in patients with HIV.

The effects of liraglutide on liver enzymes and metabolic factors in patients with nonalcoholic steatohepatitis: a meta-analysis of randomized controlled trials.

Introduction: Nonalcoholic steatohepatitis (NASH) is the most common cause of chronic liver disease, but no drug therapies have been approved to date. While glucagon-like peptide-1 (GLP-1) analogues may help in the management, the existing evidence remains conflicting. Aim: This meta-analysis aims to elucidate the efficacy of liraglutide in patients with NASH. Material and methods: We searched 4 databases for randomized controlled trials assessing the efficacy of liraglutide in patients with NASH. We analysed continuous outcomes using the mean difference (MD) and relative 95% confidence interval (CI), while dichotomous outcomes were analysed using the risk ratio (RR) and relative 95% CI. Primary endpoints included alanine aminotransferase (ALT) (IU/l), aspartate aminotransferase (AST) (IU/l), alkaline phosphatase (ALP) (IU/l), and γ-glutamyl transferase (GGT) (IU/l). Secondary outcomes were body mass index (BMI) (kg/m2), waist circumference (cm), total cholesterol (TC) (mmol/l), triglyceride (TG) (mmoll), high-density lipoprotein (HDL) (mmol/l), low-density lipoprotein (LDL) (mmol/l), and glycated hemoglobin (HbA1c) (%). Results: A total of 5 clinical trials were included. The analysis showed that liraglutide is effective in increasing HDL (MD = +0.10 (-0.18, -0.02), p = 0.02) and reducing LDL levels in blood (MD = -0.29 (-0.56, -0.02), p = 0.04). No significant difference was noted in levels of ALT (MD = 2.66 (-1.56, 6.87), p = 0.22), AST (MD = -1.99 (-5.70, 1.72), p = 0.29), GGT (MD = 5.02 (-0.86, 10.90), p = 0.09), ALP (MD = -5.16 (-11.90, 1.59), p = 0.13), TC (MD = -0.31 (-0.65, 0.03), p = 0.07), or TG (MD = -0.14 (-0.53, 0.25), p = 0.48). The HbA1c (%) level was found to be significantly reduced in the liraglutide arm (MD = -0.62 (-0.88, -0.36), p < 0.01). Conclusions: Liraglutide effectively improves the lipid profile in patients with NASH.

Effects of Aramchol in patients with nonalcoholic fatty liver disease (NAFLD). A systematic review and meta-analysis.

Introduction: Nonalcoholic fatty liver disease (NAFLD) comprises a wide range of related liver disorders affecting mainly people who drink no or very little alcohol. Aramchol is a new synthetic molecule that has been shown to reduce liver fat content. There is little evidence supporting its efficacy in humans. Aim: To evaluate the efficacy of Aramchol in patients with NAFLD according to different randomized clinical trials. Material and methods: We searched PubMed, SCOPUS, Web of Science, and Cochrane Library for relevant clinical trials assessing the use of Aramchol in patients with NAFLD. Risk of bias assessment was performed using Cochrane's risk of bias tool. We included the following outcomes: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AP), glycated haemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), HOMA-IR, and insulin level. Results: We included 3 clinical trials. We found that the Aramchol group did not show any significant difference from the control group regarding ALT (MD = 3.92 (-21.20, 29.04), p = 0.76), AP (MD = -0.59 (-8.85, 7.67), p = 0.89), HbA1c (MD = -0.11 (-0.32, 0.10), p = 0.29), TC (MD = 14.25 (-626, 34.77), p = 0.17), TG (MD = 2.29 (-39.30, 43.87), p = 0.91), HOMA-IR (MD = -0.11 (-1.58, 1.37), p = 0.89), and insulin levels (MD = -0.88 (-5.82, 4.06), p = 0.73). AST levels were significantly higher in the Aramchol group (MD =11.04 (4.91, 17.16), p = 0.04). Conclusions: Aramchol was a safe and tolerable drug to be used in patients with NAFLD. However, it was not superior to placebo in reducing the biochemical liver markers.

Experimental and numerical investigations on feasibility of inorganic KSnCl3 perovskite absorber and SWCNT-HTL for solar cells.

Inorganic metal halide perovskite materials have attracted remarkable attention as light harvesters because of their promising optoelectronic merits and photovoltaic features like tunable band gaps, high charge carrier mobilities and greater absorption coefficients. In order to explore new inorganic perovskite materials for use in optoelectronic devices Potassium Tin Chloride (KSnCl3) has been experimentally synthesized using a supersaturated recrystallization technique at ambient conditions. The resultant nanoparticle (NP) specimens were analyzed for optical and structural properties by characteristic available techniques including scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and UV visible spectroscopy. Experimental investigations about structure reveals that KSnCl3 crystallizes in orthorhombic phase with particle size of 400-500 nm. SEM showed better crystallization and EDX confirmed the accurate structural composition. UV-Visible analysis indicated a prominent absorption peak at 504 nm, and the band gap is 2.70 eV. Theoretical investigations of KSnCl3 were also carried out via AB-initio calculations in Wein2k simulation program using modified Becke Johnson (mBJ) and generalized gradient approximations (GGA). Optical properties like extinction coefficient k (ω), complex parts of dielectric constant (ε 1, ε 2), reflectivity R (ω), refractive index n (ω), optical conductivity L (ω) and absorption coefficient α (ω) were examined and it was observed that . theoretical investigations were consistent with experimental findings. Incorporation of KSnCl3 as an absorber material along with single walled carbon nanotubes as p-type materials in (AZO/IGZO/KSnCl3/CIGS/SWCNT/Au) solar cell configuration have been investigated by SCAPS-1D simulation package. Open circuit voltage (Voc) of 0.9914 V, short circuit current density (Jsc) of 47.32067 mA/cm2 and a remarkable efficiency of 36.823% with has been predicted. Thermally stable KSnCl3 may become potential source in manufacturing of photovoltaic and optoelectronic applications on large scale.

Workplace Incivility and Employee Performance: Does Trust in Supervisors Matter? (A Dual Theory Perspective).

Employee performance is the backbone of achieving competitiveness and sustainability. This study aims to examine the impact of workplace incivility on employee performance. In addition, trust in supervisors is examined as a mediator. The conservation of resources (COR) theory and Maslow's hierarchy of needs theory provided the grounds for developing the framework. The data were collected through closed-ended questionnaires and were analyzed using structural equation modeling with SmartPLS. The results affirmed that incivility is harmful to the performance of employees, and that trust in supervisors helps employees to perform well. The trust in the supervisor significantly mediates the incivility-performance relationship. The examination of the proposed model through the lens of two theories as well as the study of low-intensity deviant workplace behavior in a collectivist and developing economy are the contributions of this study to the growing body of literature. However, the use of a single sector was one of the limitations of this study.

Fluorene intercalated graphene oxide based CoQ10 imprinted polymer composite as a selective platform for electrochemical sensing of CoQ10.

The new objective of sustainable analytical chemistry is to develop validated robust, swift, simple and highly sensitive analytical methods that are based on cost effective sensing technology. Therefore, in this study the electro-chemical detection of coenzyme Q10 (CoQ10) was achieved using a fluorene intercalated graphene oxide based CoQ10 imprinted polymer composite modified glassy carbon electrode (CoQ10-IGOPC/GCE). The synthesized sensing material was characterized using SEM, XRD and FT-IR to determine the morphology and functional properties. The CoQ10-IGOPC/GCE was characterized by EIS for its electrochemical properties. CoQ10 was detected selectively using Differential Pulse Voltammetry (DPV). Under ideal circumstances, a linear calibration curve with a correlation coefficient (R 2) of 0.991 was produced in the concentration range of 0.0967 to 28.7 µM. The limit of detection (LOD) and limit of quantification (LOQ) were found to be 0.029 and 0.0967 µM, respectively. Furthermore, the proposed electrochemical sensor was extremely selective, accurate and thoroughly validated with RSD values less than 5%. The developed CoQ10-IGOPC/GCE based electrochemical sensor was successfully used for the detection of CoQ10 in samples of fruits, vegetables, nuts, human blood serum and pharmaceuticals. The CoQ10-IGOPC/GCE based electrochemical method showed good percent recoveries ranging from 94 to 103 percent.

Toxic Leadership and Project Success: Underpinning the Role of Cronyism.

Project success is the backbone of competitiveness and sustainability. The study aims to examine the role of cronyism in the relationship between toxic leadership and project success while taking information technology projects as the study context. Cross-sectional data (n = 240) was collected through closed-ended survey questionnaires to record the responses of IT project employees. The structural equation modeling (SEM) technique was used for analyzing the collected data. Results revealed a negative relationship between toxic leadership and project success, while cronyism positively and significantly mediated the relationship and converted the negative relationship between TL and PS to a positive relationship.

ADH-PPI: An attention-based deep hybrid model for protein-protein interaction prediction.

Protein-protein interaction (PPI) prediction is essential to understand the functions of proteins in various biological processes and their roles in the development, progression, and treatment of different diseases. To perform economical large-scale PPI analysis, several artificial intelligence-based approaches have been proposed. However, these approaches have limited predictive performance due to the use of in-effective statistical representation learning methods and predictors that lack the ability to extract comprehensive discriminative features. The paper in hand generates statistical representation of protein sequences by applying transfer learning in an unsupervised manner using FastText embedding generation approach. Furthermore, it presents "ADH-PPI" classifier which reaps the benefits of three different neural layers, long short-term memory, convolutional, and self-attention layers. Over two different species benchmark datasets, proposed ADH-PPI predictor outperforms existing approaches by an overall accuracy of 4%, and matthews correlation coefficient of 6%. In addition, it achieves an overall accuracy increment of 7% on four independent test sets. Availability: ADH-PPI web server is publicly available at https://sds_genetic_analysis.opendfki.de/PPI/.

Safety Management and Safety Performance Nexus: Role of Safety Consciousness, Safety Climate, and Responsible Leadership.

Drawing from social system theory, social identity theory, and social exchange theory, this study examines how safety management practices are linked with employee safety performance through safety consciousness and safety climate. Furthermore, responsible leadership is introduced as a boundary condition in the safety consciousness-safety performance and safety climate-safety performance relationships. Data were collected from employees belonging to pharmaceutical firms located in different industrial zones of Lahore, Pakistan. The support is found for full mediation of safety consciousness and safety climate for the safety management and safety performance relationships. Responsible leadership moderates the safety consciousness-safety performance and safety climate-safety performance relationships so that when the safety climate is weak or the safety consciousness is low, a high level of responsible leadership enhances safety performance.
