Impact of green human resource management practises on sustainable performance: serial mediation of green intellectual capital and green behaviour.

This research aims to examine the factors that determine the sustainable performance of the hospitality sector of Pakistan. Particularly, it measures the effect of three green HRM practises on hotels' social, economic, and environmentally sustainable performance. The research model incorporates a serially mediated role of green intellectual capital and green behaviour to connect green training, green benefits and compensation, and green hiring with sustainable performance. The study uses the Social Cognitive Theory and resource-based view theory and analyses data using simple random sampling, confirmatory factor analysis, and structural equation modelling. Data is collected from the staff of hotels through a dyad approach by employing the self-administered 5-Likert scale questionnaire. The response rate is 99%, and findings show that green intellectual capital and green behaviour serially mediate amongst green performance, green training, sustainable social performance, sustainable economic performance, and environmentally sustainable performance. However, green hiring does not regress directly or partially with the components of sustainable performance. The study's originality develops green HRM practises based on sustainable performance in the hospitality sector in developing nations. The study's findings are important for achieving sustainable development goals, improving the hospitality sector performance, and employees' role in sustainable performance. The study is sector-specific, and future studies may choose the moderated role of factors to determine sustainable performance.

Pulmonary Co-Infections Detected Premortem Underestimate Postmortem Findings in a COVID-19 Autopsy Case Series.

Bacterial and fungal co-infections are reported complications of coronavirus disease 2019 (COVID-19) in critically ill patients but may go unrecognized premortem due to diagnostic limitations. We compared the premortem with the postmortem detection of pulmonary co-infections in 55 fatal COVID-19 cases from March 2020 to March 2021. The concordance in the premortem versus the postmortem diagnoses and the pathogen identification were evaluated. Premortem pulmonary co-infections were extracted from medical charts while applying standard diagnostic definitions. Postmortem co-infection was defined by compatible lung histopathology with or without the detection of an organism in tissue by bacterial or fungal staining, or polymerase chain reaction (PCR) with broad-range bacterial and fungal primers. Pulmonary co-infection was detected premortem in significantly fewer cases (15/55, 27%) than were detected postmortem (36/55, 65%; p < 0.0001). Among cases in which co-infection was detected postmortem by histopathology, an organism was identified in 27/36 (75%) of cases. Pseudomonas, Enterobacterales, and Staphylococcus aureus were the most frequently identified bacteria both premortem and postmortem. Invasive pulmonary fungal infection was detected in five cases postmortem, but in no cases premortem. According to the univariate analyses, the patients with undiagnosed pulmonary co-infection had significantly shorter hospital (p = 0.0012) and intensive care unit (p = 0.0006) stays and significantly fewer extra-pulmonary infections (p = 0.0021). Bacterial and fungal pulmonary co-infection are under-recognized complications in critically ill patients with COVID-19.

Green HRM, green innovation and environmental performance: the role of green transformational leadership and green corporate social responsibility.

The current study attempted to inspect the influence of green human resource management (GHRM) practices and green innovation (GI) on environmental performance. Besides, the study considered green corporate social responsibility (GCSR) as a mediator to elaborate on the influence of GHRM and green innovation on environmental performance. Additionally, the current study assessed the role of green transformational leadership (GTFL) by the focus on GHRM and GI on GCSR. Data were gathered from 310 employees who are working in public and private banks by using a survey questionnaire. Subsequently, the data were analysed by using the partial least square structural equation modelling technique. The study findings showed that GHRM and GI positively influenced GCSR. In addition, the results revealed an insignificant relationship between GHRM and environmental performance (EP), whereas the influence of GI on environmental performance was significant. Moreover, GCSR positively influenced environmental performance. The results supported the mediator task of GCSR between the influence of GHRM and GI on EP. Finally, the findings indicated GTFL as a significant moderator. The study was theoretically grounded on NRBV theory. The study adds to the GHRM, GTFL, GCSR, green innovation and environmental performance theory in novel ways. The study also added to the literature by providing evidence on how transformational leadership can serve as a booster to transform the influence of GHRM on GCSR.

Seroprevalence of Hepatitis B, Hepatitis C, Human Immunodeficiency Virus, syphilis, and malaria among blood donors at tertiary care hospital blood bank.

OBJECTIVE: To ascertain the frequency of markers of transfusion-transmitted infections among blood donors in a tertiary care setting. METHODS: The retrospective cross-sectional descriptive study, was conducted in the Blood Bank section of the Department of Pathology at the Dow University of Health Sciences, Karachi, and comprised data of blood donors from January 2013, to October 2018. All blood donors had been screened for hepatitis B, hepatitis C, human immunodeficiency virus I and II, syphilis through electrochemiluminescence and malaria using immunochromatography. Data was analyzed using SPSS 21. RESULTS: Of the 29,732 donors, 29,712(99.93%) were males and 20(0.06%) were females; 12(0.04%) were volunteers and 29,720(99.95%) were exchange donors. Overall, 2587(8.7%) donors were positive for an infectious disease; 908(3%) hepatitis C virus, 887(2.9%) hepatitis B, 620(2%) syphilis, 168(0.5%) human immunodeficiency virus and 4(0.02%) malaria. CONCLUSIONS: Hepatitis C and B were the most frequent infections, followed by syphilis in the sample.

SARS-CoV-2 infection of the oral cavity and saliva.

Despite signs of infection-including taste loss, dry mouth and mucosal lesions such as ulcerations, enanthema and macules-the involvement of the oral cavity in coronavirus disease 2019 (COVID-19) is poorly understood. To address this, we generated and analyzed two single-cell RNA sequencing datasets of the human minor salivary glands and gingiva (9 samples, 13,824 cells), identifying 50 cell clusters. Using integrated cell normalization and annotation, we classified 34 unique cell subpopulations between glands and gingiva. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral entry factors such as ACE2 and TMPRSS members were broadly enriched in epithelial cells of the glands and oral mucosae. Using orthogonal RNA and protein expression assessments, we confirmed SARS-CoV-2 infection in the glands and mucosae. Saliva from SARS-CoV-2-infected individuals harbored epithelial cells exhibiting ACE2 and TMPRSS expression and sustained SARS-CoV-2 infection. Acellular and cellular salivary fractions from asymptomatic individuals were found to transmit SARS-CoV-2 ex vivo. Matched nasopharyngeal and saliva samples displayed distinct viral shedding dynamics, and salivary viral burden correlated with COVID-19 symptoms, including taste loss. Upon recovery, this asymptomatic cohort exhibited sustained salivary IgG antibodies against SARS-CoV-2. Collectively, these data show that the oral cavity is an important site for SARS-CoV-2 infection and implicate saliva as a potential route of SARS-CoV-2 transmission.

Disseminated Fungal Infection On Bone Marrow Trephine In An Asplenic Patient.

hyposplenism increases the risk of life-threatening infection with encapsulated bacteria. however, literature review revealed that hyposplenism is also a risk factor for disseminated fungal infection. here, we report a case of individual who presented with pyrexia of unknown origin and had splenectomy for hemolytic anemia and later he found to have disseminated fungal infection on bone marrow examination. this case emphasized the likelihood of disseminated fungal infection in an asplenic patient and also importance of bone marrow trephine in prompt diagnosis and management of patient.

Adenoid cystic carcinoma of the salivary gland metastasizing to the pericardium and diaphragm: Report of a rare case.

BACKGROUND: Adenoid cystic carcinoma (AdCC) is an uncommon malignancy of the salivary gland characterized by slow growth, increased risk of recurrence and poor prognosis. The annual incidence in the United States is approximately 1200 cases per year and rarely involves the body cavities. CASE PRESENTATION: We present a case of a 48-year-old male diagnosed with AdCC of the left submandibular gland. He received his last chemotherapy in 2006 and presented with pleural metastasis. After undergoing pleurectomy and decortication procedure, pericardial fluid and biopsies from the chest wall, sixth rib, diaphragm, pleural cavity and pericardium were sent for pathologic evaluation. A diagnosis of metastatic adenoid cystic carcinoma was confirmed, including in the pericardium, pericardial fluid and diaphragm. CONCLUSION: AdCC of the submandibular gland is a malignant tumor with a high mortality rate. It is very rare for AdCC to metastasize to the pericardium and diaphragm. Metastasis to uncommon sites such as seen in our case with metastases to the pericardium and diaphragm shows the aggressive and unpredictable nature of this tumor, requiring close follow up, and indicating the need for molecular profile analysis and biomarker-stratified clinical trials.

Frequency Of TP53 Gene Mutation In Patients With Chronic Lymphocytic Leukaemia.

BACKGROUND: Chronic lymphocytic leukaemia (CLL), an indolent but malignant lymphoproliferative disorder, is characterized by unregulated and uninhibited growth of mature monoclonal lymphocytes, with deletion of 17p containing TP53 gene being the most important prognostic factor. TP53 mutations, reported in 10% of CLL cases, seem to have a direct correlation to a more advanced stage and aggressive transformation of CLL. METHODS: This was a retrospective cross-sectional descriptive study limited to a period from 1st June 2013 to 30th June 2016, conducted at Section of haematology, Department of Pathology and Laboratory Medicine, Aga Khan University Hospital, Karachi. One thirty-nine cases of CLL received for TP53 mutation analysis at the Aga Khan University hospital clinical Laboratory were included in the study. Five ml of whole blood or one ml of bone marrow aspirate sample in EDTA tube was collected for the detection of TP53 mutation by the FISH technique. Statistical package for social sciences 21 was used for data entry and analysis. RESULTS: Of the 139 chronic lymphocytic leukaemia patients, 43 (31%) were females and 96 (69%) were males. The mean age of all patients was 56.3±10.84 years. Tp53 gene mutation in patients with chronic lymphocytic leukaemia was found only in 19(13.7%) patients. Among these patients 15 (10.9%) were male and 04(2.9%) were females. Age and gender were not statistically significant with Tp53 mutation with a p-value > 0.05 at a 95% confidence interval. CONCLUSIONS: In a cohort of Pakistani patients with Chronic lymphocytic leukaemia, TP53 gene mutation was found in 19 (13.7%).

Compliance of hand written transfusion requisition form and improvement after online request - a clinical audit.

OBJECTIVE: To assess the compliance of healthcare personnel with regard to sending completely filled transfusion requisition forms. METHODS: The audit was conducted at Aga Khan University Hospital, Karachi, and comprised requisition slips received at the hospital blood bank from September 2014 to February 2015. The British Committee for Standards in Haematology guidelines was used as the standard. Percentage of each variable on the proforma was analsyed. Rating <50% for each form was defined as "needs improvement", 51-99% as "good compliance" and 100% as "excellent compliance". After implementing strategies to increase awareness and the launching of an online transfusion requisition form, a re-audit of physician compliance was done from February to April 2016 and the results were compared with the initial audit.. Data was analysed using SPSS 21. RESULTS: The audit and the re-audit both comprised 1000 transfusion requisition forms each. In the audit, The sum of total scores of all the transfusion requisition forms was 4911, indicating a compliance rate of 46.9%, while the corresponding numbers in the re-audit were 10000 and 100%. CONCLUSIONS: The implementation of online blood transfusion requisition system had a positive impact on compliance rate.
