    Attempts to cultivate sugar beet (Beta vulgaris spp. vulgaris) in the sub-tropical saline soils are ongoing because of its excellent tolerance to salinity. However, the intrinsic adaptive physiology has not been discovered yet in the sub-tropical climatic conditions. In this study, we investigated morpho-physiological attributes, biochemical responses, and yield of sugar beet under a gradient of salinity in the soil-pot culture system to evaluate its adaptive mechanisms. Results exhibited that low and high salinity displayed a differential impact on growth, photosynthesis, and yield. Low to moderate salt stress (75 and 100 mM NaCl) showed no inhibition on growth and photosynthetic attributes. Accordingly, low salinity displayed simulative effect on chlorophyll and antioxidant enzymes activity which contributed to maintaining a balanced H2O2 accumulation and lipid peroxidation. Furthermore, relative water and proline content showed no alteration in low salinity. These factors contributed to improving the yield (tuber weight). On the contrary, 250 mM salinity showed a mostly inhibitory role on growth, photosynthesis, and yield. Collectively, our findings provide insights into the mild-moderate salt adaptation strategy in the soil culture test attributed to increased water content, elevation of photosynthetic pigment, better photosynthesis, and better management of oxidative stress. Therefore, cultivation of sugar beet in moderately saline-affected soils will ensure efficient utilization of lands

    Lockdown measures in response to the COVID-19 pandemic had an appreciable impact on the education of all medical, dental, and non-medical healthcare professional (HCP) students. These included the closure of universities necessitating a rapid move to e-learning and new approaches to practical’s. However initially, there was a lack of knowledge and expertise regarding e-learning approaches and the affordability of internet bundles and equipment. We initially con-ducted two pilot studies to assess such current challenges, replaced by a two-stage approach including a full investigation involving 32 private and public universities during the early stages of the pandemic followed by a later study assessing the current environment brought about by the forced changes. Top challenges at the start of the pandemic included a lack of familiarity with e-learning approaches, cost of the internet, lack of IT equipment and the quality of the classes. Universities offered support to staff and students to a varying degree to address identified challenges. Since then, e-learning approaches have widened the possibilities for teaching and learning at convenient times. However, challenges remain. In conclusion, there were considerable challenges at the start of them pandemic. Several key issues have been addressed with hybrid learning here to stay. Remaining challenges include a lack of ICT equipment. However, new innovations will continue

    Proximity, interpenetration, and sympatry networks: A Reply to Dos Santos et al.

    Whereas our examples are hypothetical, they all consist of patterns of coextensive sympatry easily revealed by visual inspection and properly detected by a method like that of Szumik and Goloboff (2004) but missed by SyNet. In actual studies, real distributions of species may not present the properties which mislead SyNet, but there is no way to know in advance whether this will be the case. It is entirely possible that, as assumed by SyNet, most of the areas of endemism will prove to be disjoint and nonoverlapping and that sympatry between species will prove to be either complete or nonexistent. But the only way to demonstrate that empirical data support such a type of distribution is by using methods which?unlike that of Dos Santos et al.?do not force the results to conform to that pattern.Fil: Casagranda, Maria Dolores.

    Papillary muscles are one of the important components of the musculature of the ventricles of the heart. Various diseases of papillary muscle dysfunction such as papillary muscle ischemia, left ventricular dilation, non-ischemic papillary muscle atrophy, papillary muscle or chordae congenital anomalies, dilated or hypertrophic cardiomegaly are commonly observed. Apparently normal postmortem hearts (n=60) were used in this study. Based on gender, specimens were grouped as follows: group A (n=41) ‘male’ and group B (n=19) ‘female’. The length and breadth of the anterior, posterior and septal papillary muscles were measured. The mean length of the anterior papillary muscle was 17.27 (±4.30) mm in males, 16.98 (±3.70) mm in females, the posterior papillary muscle was 14.04 (±3.78) mm in males, and 13.81 (±2.47) mm in female, and septal papillary muscle was 7.35 (±2.78) mm in male and 6.73 (±1.94) mm in female. The breadth of anterior papillary muscle was 5.75 (±1.24) mm and 5.94 (±1.76) mm, posterior papillary had 5.02 (±1.09) mm and 4.77 (±0.80) mm, and septal papillary was 3.97 (±0.81) mm and 3.86 (±0.38) mm in male and female accordingly.&nbsp

    Association between flaunting behaviors on social media and among the general population in Bangladesh: A cross‐sectional study

    No full text
    Abstract Background and Aims The number of social media users is growing with each passing day at full tilt, keeping pace with digitalization and technological advances. Despite several advantages, there are also certain negative aspects to using social networking sites (SNS) for communication, amusement, self‐expression, impression management, and other purposes. This study sought to investigate the association between mental health status and flaunting behaviors in social media among the general population in Bangladesh. Methods We conducted this nationwide cross‐sectional online survey among 465 people aged between 18 and 60 between October 15, 2021 and January 15, 2022. Following electronic consent, we collected the socio‐demographic profiles and psychometric parameters of the respondents. Additionally, we assessed the diverse perspectives on SNS usage and its relationship to the self‐reported symptoms of depression and loneliness. Results The estimated prevalence of loneliness and depressive symptoms were 65.16% (mild: 39.57%, moderate: 16.56%, severe: 9.03%) and 55.49% (mild: 26.67%, moderate: 22.15%, severe: 6.67%), respectively. Key factors associated with flaunting on social media were mental health issues such as depression and loneliness. Several social factors were also considered, such as being young, of the male sex, unmarried, illiterate, a student, urban dwelling, average economic status, nuclear family structure, types of SNSs, checking social media first in the morning, and the use of SNS for gaining popularity. Conclusion A significant portion of SNS users reported symptoms of mental illness. Current study findings urge for longitudinal studies with larger sample sizes to have a nearly equal distribution of users from each social media platform for in‐depth exploration of how user attitudes about SNSs and site usage patterns impact the general public's mental health. We suggest that regulating SNS usage patterns and treatment approaches would improve the situation

    © 2021 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY-NC-ND 4.0 licenseBackground: 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods: This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. Findings: Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation: Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

    © 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: 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.
