USAGE OF SMARTPHONE BY HIGH SCHOOL STUDENTS: A STUDY ON JHIKARGACHA SUB-DISTRICT OF BANGLADESH
Students now have more access to online courses thanks to the COVID-19 pandemic. The current study included high school students and aimed to comprehend the drivers behind smartphone use as well as the consequences of smartphone consumption. The school-based work in the sub-district area is not seen in that way, despite the fact that there are numerous forms of research on the use of mobile phones in the context of the city, college, or university. Bangladesh's upazila (subdistricts), in particular, do not have a lot of school-related work. The study uses a quantitative approach. In order to choose Jhikargacha Upazila of Jessore District, which is situated in the Southwest of Bangladesh, purposive sampling is utilized. Additionally, three schools were purposefully selected for data collection. A further offline survey was used to collect data, and SPSS version 24 was used to analyze the findings. In addition, the facts and context of smartphone usage are analyzed using the uses and gratification theory. Most participants claimed to use their smartphones for a range of purposes and to devote varying amounts of time to each. When the corona pandemic forces all educational activities to be conducted online, they are using cellphones. Additionally, certain changes in their daily routine have been brought about by using a smartphone. Some of them think it affects their day-to-day activities by making them feel detached from reality, stay up late, experience worry and melancholy, etc. Article visualizations
Work‐related respiratory symptoms and pulmonary function tests in northeast iranian (the city of Mashhad) carpenters
OBJECTIVE: To assess the respiratory symptoms and pulmonary function of carpenters from the city of Mashhad (northeast Iran). METHODS: The frequency of respiratory symptoms was retrospectively estimated in a sample of 66 carpenters in the city of Mashhad in northeast Iran using a questionnaire including questions on work-related respiratory symptoms in the past year, allergy, type of irritant chemicals that induce respiratory symptoms, smoking habits, and working periods as a carpenter. PFT values were also measured in all participants, and the age and smoking habits matched those of a sample of men from the general population as a control group. RESULTS: Thirty-five carpenters (53%) reported work-related respiratory symptoms. Cough (34.4%) and sputum (33.3%) were the most common symptoms, and only 15.15% of carpenters reported wheezing during work. All respiratory symptoms were higher in carpenters than in controls, which was statistically significant for cough and sputum (p<0.001 in both cases). Most allergic symptoms were also significantly greater among the carpenters than in the control group (p<0.05 for both itchy eyes and sneezing). Most respiratory and allergic symptoms in the carpenters increased during work compared to rest period which was statistically significant only for cough (p<0.05). PFT values were significantly lower in the carpenters than in control subjects (p<0.05 to p<0.001). CONCLUSIONS: Carpentry work was associated with a high frequency of respiratory symptoms, particularly after exposure to irritating chemicals during work. PFT values were also significantly reduced among carpenters compared to controls
Implementing components of the primary health care pre-eclampsia/eclampsia model in Bangladesh: A cost analysis
Between 2016 and 2018, the Population Council, in collaboration with the Directorate General of Family Planning and Obstetrical and Gynecological Society of Bangladesh, implemented an intervention to confront pre-eclampsia/eclampsia (PE/E). This was part of the Ending Eclampsia project, a five-year USAID investment that implemented aspects of the Primary Health Care (PHC) PE/E Model in Bangladesh, Nigeria, and Pakistan. The intervention in Bangladesh comprised two components of the PHC for PE/E Model: 1) Task sharing to detect and manage PE/E (MgSO4 and referral) with PHC providers (Family Welfare Visitors, Sub-Assistant Community Medical Officers, and Nurse-Midwives), and 2) Introducing antihypertensive drug provision at the PHC level. This brief describes the true cost for implementing the two components in Bangladesh and includes a brief description of the activities within each component. Lessons from implementation of the PHC PE/E Model in Bangladesh could lead to cost savings in future interventions
Chirality-induced Spin Selectivity in Functionalized Carbon Nanotube Networks: The Role of Spin-orbit Coupling
Spin–orbit coupling in a chiral medium is generally assumed to be a necessary ingredient for the observation of the chirality-induced spin selectivity (CISS) effect. However, some recent studies have suggested that CISS may manifest even when the chiral medium has zero spin–orbit coupling. In such systems, CISS may arise due to an orbital polarization effect, which generates an electromagnetochiral anisotropy in two-terminal conductance. Here, we examine these concepts using a chirally functionalized carbon nanotube network as the chiral medium. A transverse measurement geometry is used, which nullifies any electromagnetochiral contribution but still exhibits the tell-tale signs of the CISS effect. This suggests that CISS may not be explained solely by electromagnetochiral effects. The role of nanotube spin–orbit coupling on the observed pure CISS signal is studied by systematically varying nanotube diameter. We find that the magnitude of the CISS signal scales proportionately with the spin–orbit coupling strength of the nanotubes. We also find that nanotube diameter dictates the supramolecular chirality of the medium, which in turn determines the sign of the CISS signal
Abemaciclib in combination with pembrolizumab for HR+, HER2- metastatic breast cancer: Phase 1b study.
This nonrandomized, open-label, multi-cohort Phase 1b study (NCT02779751) investigated the safety and efficacy of abemaciclib plus pembrolizumab with/without anastrozole in patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (MBC) without prior CDK4 and 6 inhibitor exposure. Patients were divided into two cohorts: treatment naïve (cohort 1) and pretreated (cohort 2). Patients received abemaciclib plus pembrolizumab with (cohort 1) or without (cohort 2) anastrozole over 21-day cycles. The primary objective was safety, and secondary objectives included efficacy and pharmacokinetics (PK). Cohort 1/2 enrolled 26/28 patients, respectively. Neutropenia (30.8/28.6%), AST increase (34.6/17.9%), ALT increase (42.3/10.7%), and diarrhea (3.8/10.7%) were the most frequent grade ≥3 adverse events in cohort 1/2, respectively. A total of two deaths occurred, which investigators attributed to treatment-related adverse events (AEs), both in cohort 1. Higher rates of all grade and grade ≥3 interstitial lung disease (ILD)/pneumonitis were observed compared to previously reported with abemaciclib and pembrolizumab monotherapy. The PK profiles were consistent between cohorts and with previous monotherapy studies. In cohorts 1/2, the overall response rate and disease control rate were 23.1/28.6% and 84.6/82.1%, respectively. Median progression-free survival and overall survivals were 8.9 (95% CI: 3.9-11.1) and 26.3 months (95% CI: 20.0-31.0) for cohort 2; cohort 1 data are immature. Abemaciclib plus pembrolizumab demonstrated antitumor activity, but high rates of ILD/pneumonitis and severe transaminase elevations occurred with/without anastrozole compared to the previous reporting. Benefit/risk analysis does not support further evaluation of this combination in the treatment of HR+, HER2- MBC.We thank the patients and families who participated in this study, caregivers, the study investigators, and their staff, and the JPCE (NCT02779751) clinical trial team.

Systems analysis of primary Sjögren's syndrome pathogenesis in salivary glands identifies shared pathways in human and a mouse model
Introduction: Primary Sjogren's syndrome (pSS) is a chronic autoimmune disease with complex etiopathogenesis. Despite extensive studies to understand the disease process utilizing human and mouse models, the intersection between these species remains elusive. To address this gap, we utilized a novel systems biology approach to identify disease-related gene modules and signaling pathways that overlap between humans and mice. Methods: Parotid gland tissues were harvested from 24 pSS and 16 non-pSS sicca patients and 25 controls. For mouse studies, salivary glands were harvested from C57BL/6.NOD-Aec1Aec2 mice at various times during development of pSS-like disease. RNA was analyzed with Affymetrix HG U133+2.0 arrays for human samples and with MOE430+2.0 arrays for mouse samples. The images were processed with Affymetrix software. Weighted-gene co-expression network analysis was used to identify disease-related and functional pathways. Results: Nineteen co-expression modules were identified in human parotid tissue, of which four were significantly upregulated and three were downregulated in pSS patients compared with non-pSS sicca patients and controls. Notably, one of the human disease-related modules was highly preserved in the mouse model, and was enriched with genes involved in immune and inflammatory responses. Further comparison between these two species led to the identification of genes associated with leukocyte recruitment and germinal center formation. Conclusion: Our systems biology analysis of genome-wide expression data from salivary gland tissue of pSS patients and from a pSS mouse model identified common dysregulated biological pathways and molecular targets underlying critical molecular alterations in pSS pathogenesis
