Knowledge Sharing and Affective Commitment:Mediating Role of Trust Between Knowledge Sender and Receiver
The main determination of the current study is to explore the antecedents of knowledge sharing. Hence; affective commitment is an antecedent that shows how knowledge can be shared among the knowledge participants by using an employee’s emotional attachment and recognition with the organization. Similarly, the mediating role of trust was checked between employee’s knowledge sharing attitude and affective commitment. Data was collected from the hi-tech information technology (IT) industry from Pakistan with a sample of 143 as valid responses. Regression, correlation, factor loading, and path coefficients were used to check the reliability, validity, and model fit of the research framework. The findings suggested that employees’ recognition and emotional attachment with the organization are positively related to knowledge sharing. In addition, the mediating role of trust between affective commitment and knowledge sharing is significant and positive
Youth in Pakistan: Priorities, realities and policy responses
Youth is a pivotal stage during which the right policies and interventions in the health, social, educational, and economic sectors can protect young people against risks, and turn the trajectories of their lives toward a safe and productive path of growth. This report explores some of the key issues facing youth in Pakistan, in the main spheres marking their transition to adult roles. It also presents the results of an age-based segmentation analysis capturing where youth in Pakistan stand in terms of school enrollment, work force participation, and marriage, with a view to identifying the broad developmental priorities for each cohort. This is followed by a brief look at current policies and strategies, and the interventions of government and nongovernmental stakeholders for youth development. The report concludes with remarks about the adequacy of current arrangements for affording our youth healthy transitions to adulthood, and preliminary suggestions for future research and action
Adolescent girls\u27 voices on enhancing their own productivity in Pakistan
This study was conducted in the Punjab province of Pakistan to examine the lives, aspirations, and perspectives of the largely invisible and marginalized group of older adolescent girls (ages 15–19 years) who are “not in education, employment for pay or profit, nor in marriage” (“NEEM”). The study seeks to identify the reasons for the exclusion of the NEEM girls from education and participation in paid work; explore opportunities and avenues for changing these girls’ existing opportunity structures; and probe the gender norms and behaviors underlying their marginalization to obtain insights into what it would take to change their situation
Gendered effects of COVID-19 school closures: Pakistan case study
This brief summarizes a case study conducted to assess the gendered impacts of COVID-19 school closures on adolescent girls and boys in three districts in the province of Punjab in Pakistan. Data as well as discussions and interviews with adolescents, teachers, and parents shed light on difficulties in accessing and adjusting to remote learning, learning loss, deterioration of behaviors and health, and other effects. Based on these findings and further reflections by stakeholders on the successes and gaps of mitigation measures, the case study proposes recommendations for improved teacher training, digital access, alternative learning options, and a gendered focus in interventions
Artificial Extracellular Matrices Containing Bioactive Glass Nanoparticles Promote Osteogenic Differentiation in Human Mesenchymal Stem Cells
The present study analyzes the capacity of collagen (coll)/sulfated glycosaminoglycan
(sGAG)-based surface coatings containing bioactive glass nanoparticles (BGN) in promoting the
osteogenic differentiation of human mesenchymal stroma cells (hMSC). Physicochemical charac teristics of these coatings and their effects on proliferation and osteogenic differentiation of hMSC
were investigated. BGN were stably incorporated into the artificial extracellular matrices (aECM).
Oscillatory rheology showed predominantly elastic, gel-like properties of the coatings. The complex
viscosity increased depending on the GAG component and was further elevated by adding BGN.
BGN-containing aECM showed a release of silicon ions as well as an uptake of calcium ions. hMSC
were able to proliferate on coll and coll/sGAG coatings, while cellular growth was delayed on aECM
containing BGN. However, a stimulating effect of BGN on ALP activity and calcium deposition
was shown. Furthermore, a synergistic effect of sGAG and BGN was found for some donors. Our
findings demonstrated the promising potential of aECM and BGN combinations in promoting bone
regeneration. Still, future work is required to further optimize the BGN/aECM combination for
increasing its combined osteogenic effect

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study
Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Global burden of 288 causes of death and life expectancy decomposition in 204 countries and territories and 811 subnational locations, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021
BACKGROUND Regular, detailed reporting on population health by underlying cause of death is fundamental for public health decision making. Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic. When systematically analysed, mortality rates and life expectancy allow comparisons of the consequences of causes of death globally and over time, providing a nuanced understanding of the effect of these causes on global populations. METHODS The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 cause-of-death analysis estimated mortality and years of life lost (YLLs) from 288 causes of death by age-sex-location-year in 204 countries and territories and 811 subnational locations for each year from 1990 until 2021. The analysis used 56 604 data sources, including data from vital registration and verbal autopsy as well as surveys, censuses, surveillance systems, and cancer registries, among others. As with previous GBD rounds, cause-specific death rates for most causes were estimated using the Cause of Death Ensemble model-a modelling tool developed for GBD to assess the out-of-sample predictive validity of different statistical models and covariate permutations and combine those results to produce cause-specific mortality estimates-with alternative strategies adapted to model causes with insufficient data, substantial changes in reporting over the study period, or unusual epidemiology. YLLs were computed as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2·5th and 97·5th percentiles from a 1000-draw distribution for each metric. We decomposed life expectancy by cause of death, location, and year to show cause-specific effects on life expectancy from 1990 to 2021. We also used the coefficient of variation and the fraction of population affected by 90% of deaths to highlight concentrations of mortality. Findings are reported in counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2021 include the expansion of under-5-years age group to include four new age groups, enhanced methods to account for stochastic variation of sparse data, and the inclusion of COVID-19 and other pandemic-related mortality-which includes excess mortality associated with the pandemic, excluding COVID-19, lower respiratory infections, measles, malaria, and pertussis. For this analysis, 199 new country-years of vital registration cause-of-death data, 5 country-years of surveillance data, 21 country-years of verbal autopsy data, and 94 country-years of other data types were added to those used in previous GBD rounds. FINDINGS The leading causes of age-standardised deaths globally were the same in 2019 as they were in 1990; in descending order, these were, ischaemic heart disease, stroke, chronic obstructive pulmonary disease, and lower respiratory infections. In 2021, however, COVID-19 replaced stroke as the second-leading age-standardised cause of death, with 94·0 deaths (95% UI 89·2-100·0) per 100 000 population. The COVID-19 pandemic shifted the rankings of the leading five causes, lowering stroke to the third-leading and chronic obstructive pulmonary disease to the fourth-leading position. In 2021, the highest age-standardised death rates from COVID-19 occurred in sub-Saharan Africa (271·0 deaths [250·1-290·7] per 100 000 population) and Latin America and the Caribbean (195·4 deaths [182·1-211·4] per 100 000 population). The lowest age-standardised death rates from COVID-19 were in the high-income super-region (48·1 deaths [47·4-48·8] per 100 000 population) and southeast Asia, east Asia, and Oceania (23·2 deaths [16·3-37·2] per 100 000 population). Globally, life expectancy steadily improved between 1990 and 2019 for 18 of the 22 investigated causes. Decomposition of global and regional life expectancy showed the positive effect that reductions in deaths from enteric infections, lower respiratory infections, stroke, and neonatal deaths, among others have contributed to improved survival over the study period. However, a net reduction of 1·6 years occurred in global life expectancy between 2019 and 2021, primarily due to increased death rates from COVID-19 and other pandemic-related mortality. Life expectancy was highly variable between super-regions over the study period, with southeast Asia, east Asia, and Oceania gaining 8·3 years (6·7-9·9) overall, while having the smallest reduction in life expectancy due to COVID-19 (0·4 years). The largest reduction in life expectancy due to COVID-19 occurred in Latin America and the Caribbean (3·6 years). Additionally, 53 of the 288 causes of death were highly concentrated in locations with less than 50% of the global population as of 2021, and these causes of death became progressively more concentrated since 1990, when only 44 causes showed this pattern. The concentration phenomenon is discussed heuristically with respect to enteric and lower respiratory infections, malaria, HIV/AIDS, neonatal disorders, tuberculosis, and measles. INTERPRETATION Long-standing gains in life expectancy and reductions in many of the leading causes of death have been disrupted by the COVID-19 pandemic, the adverse effects of which were spread unevenly among populations. Despite the pandemic, there has been continued progress in combatting several notable causes of death, leading to improved global life expectancy over the study period. Each of the seven GBD super-regions showed an overall improvement from 1990 and 2021, obscuring the negative effect in the years of the pandemic. Additionally, our findings regarding regional variation in causes of death driving increases in life expectancy hold clear policy utility. Analyses of shifting mortality trends reveal that several causes, once widespread globally, are now increasingly concentrated geographically. These changes in mortality concentration, alongside further investigation of changing risks, interventions, and relevant policy, present an important opportunity to deepen our understanding of mortality-reduction strategies. Examining patterns in mortality concentration might reveal areas where successful public health interventions have been implemented. Translating these successes to locations where certain causes of death remain entrenched can inform policies that work to improve life expectancy for people everywhere.
