Antecedents and Mediating Role of Green Buying Behavior

Sustainability of the environment is one of the major issues both in developed and developing countries. There is an abundance of studies on green buying behavior. However, a few have studied the mediating role of green buying behavior. Thus, we have developed a new model that has five direct and three mediating relationships. This empirical research has used a snowball sampling technique for collecting the data. We distributed 400 questionnaires and received 377 valid responses. The study has used Smart PLS software for data analysis, including reliability, validity, and generating measurement and structural models. We found that green brands, green identification, and social influence are significant predictors of green buying behavior. Further, we find that the green brand image and green buying behavior promote green satisfaction. The results also suggest that green buying behavior mediates (1) green image and green satisfaction, (2) social influence and green buying behavior, (3) self-identification, and green satisfaction. We also found that consumers have a favorable attitude towards green buying behavior. However, there is a huge gap in consumers’ attitudes and actual buying behavior. Thus, marketers and practitioners need to develop strategies that would translate a favorable attitude toward actual buying behavior

Association of Sociodemographic Factors with Trends of Self-Medication Practice and Its Hazard Perception for Oral Health Problems among Patient

OBJECTIVES: To assess the impact of sociodemographic factors with the trends of self-medication practice and its hazard perception among patients METHODOLOGY: A cross sectional descriptive study was conducted on the patients visiting Sharif Medical and Dental College from June 2019 to June 2020. Data was collected using a validated questionnaire from 142 patients. Chi-square and fisher exact tests were used to find the association of trends of self-medication practice and hazard perception with sociodemographic factors. RESULTS: The patients in the age range of 18 to 29 years practiced self-medication the most. The triggering factor for use of medication was toothache among all ages. The most commonly used drug was reported to be analgesics. The main reason for self-medication was lack of time to visit the doctor. The females practiced self-medication more than the males. The triggering factor for both the genders was toothache and analgesics were mostly used. The patients with tertiary level education and those who were unemployed practiced self- medication the most. The triggering factor was toothache across all levels of education and employed as well as unemployed patients. Drug resistance was stated the main hazard. CONCLUSION: The triggering factor for use of medication was toothache, most commonly used drugs were analgesics and the main reason for self-medication was lack of time across all ages, both the gender, married and unmarried patients, levels of education and employment. Un-employed patients and those with tertiary level of education-practiced self- medicated themselves the most. The highest percentage of patients considered drug resistance to be the biggest hazard

Multidisciplinary Management and Outcome of Intradural Extramedullary Spinal Tumors

Introduction/Objective:  About fifteen percent of the primary CNS tumors are intraspinal. About two-thirds of tumors are intradural extramedullary (IDEM). This study was conducted to review the outcome of operative management of intradural extramedullary tumors in correlation with the factors, both clinical & histopathological, influencing the neurology of patients & prognosis. Materials and Methods:  It was a multicenter study including 42 patients conducted from December 2018 to December 2020. All patients were diagnosed by MRI with and without contrast. Patients were surgically treated & analyzed for clinical features i.e., pain by visual analog scale (VAS) & neurology by modified McCormick scale both preoperatively & post-operatively. Clinical features & outcomes were correlated with tumor size & histopathology. p-value < 0.05 was considered significant. Results:  This study included 42 cases. The most common diagnosis was schwannoma (76.19%). The average intradural space occupied at presentation was 82%. The most common location was dorsal (90.4%). The visual analog score for pain (VAS) improved in all patients post-operatively from 7 ± 1.9 to 2 ± 0.8 (p = 0.003) & modified McCormick scale from 3.0 ± 1.3 to 2.0 ± 1.0 (p = 0.005). The preoperative symptoms were correlated with the only size of the tumor occupying the intradural space (VAS p = 0.021, modified McCormick scale p = 0.018). Conclusion:  All the tumors excised showed some improvement in neurological status. Therefore, all patients diagnosed with IDEM should be operated on even if present with prolonged symptoms or severe neurological compromise.

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

Kinetic and Isothermal Investigations of Cost-Effective Sorptive Elimination of Gentian Violet Dye from Water Using Haplophragma adenophyllum Biowaste

A novel biosorbent, Haplophragma adenophyllum (HAB) was employed to explore the biosorption mechanism of Gentian Violet (GV) dye. The novel sorbent was characterized by using FTIR spectra and physiochemical analysis. The effect of different optimizing factors like HAB dosage, GV initial concentration, contact time between sorbent and sorbate, pH of a solution, and the temperature was studied. The optimum removal of GV by HAB was observed at pH 6.0. The equilibrium study was carried out using Langmuir and Freundlich isotherms. Experimental data fitted well in Langmuir isotherm indicating monolayer isotherm with qmax value obtained at optimum process condition of 13.21 mg/g. Kinetics study was carried out and followed by pseudo-second-order model. Thermodynamics studies reveal the endothermic reaction

Determinants of environmental degradation: Exploring the unexplored for brunei darussalam

This paper identifies the determinants of environmental degradation for the resource-rich economy of Brunei Darussalam. Annual data for selected variables on the economy of Brunei Darussalam is obtained from the World Development Indicators (WDI) for the period 1990–2020. To explore the potential cointegration relationship between environmental degradation and its determinants, we apply autoregressive distributed lagged modeling (ARDL). The long-run findings indicated that an increasing income level and energy consumption had caused environmental degradation in Brunei Darussalam, as their coefficients are positive and statistically significant. On the other hand, trade openness has improved the overall quality of the environment in Brunei Darussalam as its impact on CO2 emissions is negative and statistically significant. Urbanization has a negative but insignificant influence on CO2 emissions. The short-run results showed that trade openness, urbanization, and energy consumption had degraded the quality of the environment. Our causality analysis show that CO2 emissions are unilaterally related to GDP per capita and energy consumption, while energy consumption casts a one-way impact on GDP per capita. Moreover, urbanization is unilaterally causing CO2 emissions, energy consumption, and GDP per capita. Finally, a one-way causal relationship is seen between trade openness and energy consumption. Overall, our results are quite interesting as the long-run and short-run determinants of environmental degradation are not uniform. The study's findings provide practical insights for Brunei Darussalam's policymakers to cope with ecological degradation

Complex Karyotype in Hematological Diseases: A 6-Year Single Centre Study from Pakistan

Background. Most of the hematological disorders are heterogenous with regard to morphology, immunophenotype, and genetic rearrangements. Multiple recurrent chromosomal aberrations have been identified by conventional cytogenetic analysis, which is now widely recognized as one of the most important diagnostic and prognostic determinants in these patients. Though rarer, complex karyotype has been associated with worst prognosis. Materials and Methods. A total of 1185 bone marrow or peripheral blood cytogenetics samples were taken with different hematological diseases. They included both benign and malignant disease entities. In each case, cells were cultured and conventional cytogenetic analysis was performed. Results. Among 1185 subjects, 41 (3.4%) patients possessed complex cytogenetic abnormalities. Out of these 41, 33 (80%) were males. The mean age was 37 years (median age 39 years). Myelodysplastic syndromes had the most numbers of complex karyotypes (8%), followed by acute myeloid leukemia (7%) and acute lymphoblastic leukemia (4%). Also we found few patients with acute promyelocytic leukemia, aplastic anemia , chronic myeloid leukemia, and diffuse large B cell Lymphoma possessing complex karyotype. Frequencies of different cytogenetic abnormalities were assessed with respect to disease as well as independently. Trisomy 21 was the most common chromosomal abnormality found in 28% of patients. Conclusion. Complex karyotype was most frequently associated with myelodysplastic syndromes and acute myeloid leukemia. Trisomy 21 and deletion 5q were the commonest cytogenetic abnormalities found. We also assessed complex karyotype in benign diseases and detected one patient of aplastic anemia with complex karyotype. This is the first study highlighting the presence of complex karyotypes in hematological disorders in our region

A Novel Method of Magnetic Nanoparticles Functionalized with Anti-Folate Receptor Antibody and Methotrexate for Antibody Mediated Targeted Drug Delivery

Therapeutic effects of anticancer medicines can be improved by targeting the specific receptors on cancer cells. Folate receptor (FR) targeting with antibody (Ab) is an effective tool to deliver anticancer drugs to the cancer cell. In this research project, a novel formulation of targeting drug delivery was designed, and its anticancer effects were analyzed. Folic acid-conjugated magnetic nanoparticles (MNPs) were used for the purification of folate receptors through a novel magnetic affinity purification method. Antibodies against the folate receptors and methotrexate (MTX) were developed and characterized with enzyme-linked immunosorbent assay and Western blot. Targeting nanomedicines (MNP-MTX-FR Ab) were synthesized by engineering the MNP with methotrexate and anti-folate receptor antibody (anti-FR Ab). The cytotoxicity of nanomedicines on HeLa cells was analyzed by calculating the % age cell viability. A fluorescent study was performed with HeLa cells and tumor tissue sections to analyze the binding efficacy and intracellular tracking of synthesized nanomedicines. MNP-MTX-FR Ab demonstrated good cytotoxicity along all the nanocomposites, which confirms that the antibody-coated medicine possesses the potential affinity to destroy cancer cells in the targeted drug delivery process. Immunohistochemical approaches and fluorescent study further confirmed their uptake by FRs on the tumor cells’ surface in antibody-mediated endocytosis. The current approach is a useful addition to targeted drug delivery for better management of cancer therapy along with immunotherapy in the future
