RESUMO
Salinized land is slowly spreading across the world. Reduced crop yields and quality due to salt stress threaten the ability to feed a growing population. We discussed the mechanisms behind nano-enabled antioxidant enzyme-mediated plant tolerance, such as maintaining reactive oxygen species (ROS) homeostasis, enhancing the capacity of plants to retain K+ and eliminate Na+, increasing the production of nitric oxide, involving signaling pathways, and lowering lipoxygenase activities to lessen oxidative damage to membranes. Frequently used techniques were highlighted like protecting cells from oxidative stress and keeping balance in ionic state. Salt tolerance in plants enabled by nanotechnology is also discussed, along with the potential role of physiobiochemical and molecular mechanisms. As a whole, the goal of this review is meant to aid researchers in fields as diverse as plant science and nanoscience in better-comprehending potential with novel solutions to addressing salinity issues for sustainable agriculture.

Background: Patients with end-stage liver disease (ESLD) have a poor quality of life, which often worsens as disease severity increases. Palliative care (PC) has emerged as a management option in ESLD patients, especially for those who are not candidates for a liver transplant. Objective: To assess the associated factors and trends in PC utilization in recent years. Design: We used the 2016-2020 National Inpatient Sample (NIS) database of the United States to identify patients with decompensated cirrhosis who suffered in-hospital mortality. Information regarding patient demographics, hospital characteristics, etiology and decompensations, Elixhauser comorbidities, and interventions was collected. The multivariate regression model was used to identify factors associated with PC use. Results: Out of 98,160 patients, 52,645 patients (53.6%) received PC consultations. PC utilization increased from 49.11% in 2016 to 56.85% in 2019, with a slight decrease to 54.47% in 2020. Patients with PC use had decreased incidence of blood transfusions (28.85% vs. 36.53%, p < 0.001), endoscopy (18% vs. 20.26%, p 0.0001), liver transplantation (0.28% vs. 0.69%, p < 0.001), and mechanical ventilation (46.22% vs. 56.37%, p < 0.001). African American, Hispanic, and Asian/Pacific Islander patients had 29%, 27%, and 23% lower odds of receiving PC than White patients. Patients in the two lowest income quartiles had 12% and 22% lower odds of receiving PC compared with the highest quartile. Conclusions: PC utilization in patients with ESLD is associated with decreased invasive procedures, shorter lengths of stay, and lower hospitalization charges. Minorities, as well as patients in the lower income quartiles, were less likely to receive PC.

Background: COVID-19 pandemic affected millions of people worldwide. Alcohol consumption increased during the pandemic, leading to rising numbers of cases of alcohol-related pancreatitis. We aimed to assess the mortality of alcohol-induced pancreatitis during the COVID-19 pandemic in the United States. Methods: We analyzed the National Vital Statistical System's (NVSS) provisional multiple causes of death data, provided by the Centers for Disease Control and Prevention, to assess the mortality of alcohol-induced pancreatitis during the pandemic. Patients with alcohol-induced pancreatitis as a cause of death were analyzed between 2018 and 2021. Patient demographics such as age, sex, ethnicity, and location were studied. Results: During 2018-2021, there were 2547 deaths from alcohol-induced pancreatitis. The total cases and age-adjusted rates of alcohol-induced pancreatitis per 100,000 were similar in 2018 (n=515) and 2019 (n=501) (crude rate=0.1). The number increased to 747 in 2020 and 784 in 2021 (crude rate=0.2). A statistically significant increase in mortality rates was noted in all age groups except 75-84. An increase in mortality in both males and females was noted (48% increase and 64% increase, respectively, P<0.001). The number of deaths increased in both Hispanics (59%, P<0.001) and non-Hispanics (48%, P<0.001). Conclusions: Our analysis demonstrated a substantial increase in the mortality of patients with alcohol-induced pancreatitis during the first 2 years of the COVID-19 pandemic. The increase in alcohol consumption and the burden on mental health caused massive collateral damage to society. Urgent public health interventions are needed at state and national levels to prevent further rise in cases.
RESUMO
Deficits in the mineral Zn are responsible for a sizable proportion of the world's disease burden and child mortality. With the increasing success rate of biofortification in major crops, the development of a genotype with enhanced Zn bioavailability will be an efficient and sustainable solution to nutrient deficiency-related problems. Due to the complex chemistry of the human system, the absorption of Zn from cereals is lower. This complexity is alleviated by phytate, a major phosphorus-storing compound in cereal and legume seeds, which negatively affects Zn binding. The results of recent studies on the distribution of elements and micronutrient speciation in seeds provide strong evidence for the presence of distinct Zn pools. This observation is supported by data from biofortified transgenic plant research. Several studies identify nicotinamide, a metal chelator, as a pivotal molecule. The loading of Zn into grains has been reported to increase with nicotinamide levels, which is a crucial finding. Intestinal Zn absorption can be greatly improved by nicotinamide. Furthermore, bioavailability tests suggest that the use of nano Zn-enabled devices could be an effective strategy to enable plant biofortification, which may significantly boost the Zn content in various cereal crops. This review comprehensively evaluated the scientific publications indexed in WoS, Scopus, and various other reliable databases and explored insights into how nano-enabled technology could be a solution for enhancing Zn content in cereal crops for combating malnutrition in humans.

INTRODUCTION: With growing trends in tobacco consumption, it has been observed that the age of initiation is gradually decreasing. To combat the deep-rooted problem of the Society, we need to target the adolescents at the time of their first consumption of tobacco forms. Hence, this study was conducted to assess the pattern of smokeless tobacco use among school going adolescents in senior secondary schools with the assessment of the sociodemographic factors responsible for initiation of smokeless tobacco use by adolescents. METHODS: A cross-sectional survey of total sample of 714 students across 9-11 standards in 3 schools of Delhi was done using a self-administered questionnaire after obtaining approval from Institutional Ethics Committee and School Health Scheme, Delhi. RESULT: Consumption of tobacco was found to be 27.9% at a frequency of 6-9 days in a period of one month and a majority of 31 (39.2%) students initiated the use in the age group of 10-11 years. Among the different SLT products, pan masala combined with zarda with 56 (70.8%) users, was found to be the most commonly consumed SLT product. Grocery shops were preferred POS among the students as (67%) of students obtained the SLT product from this POS. 56 (70.8%) of the students wanted to quit the habit of SLT use whereas 49 (62%) students tried to quit the habit and 43 (54.4%) students sought help in order to quit the habit. DISCUSSION: Such alarming results in terms of low age of initiation in Delhi is an emerging health problem. Adequate cessation programmes and schemes must be developed and strict implementation of laws and policies to achieve a tobacco free youth is the need of hour.

BACKGROUND: Patients are increasingly referred for conversion of laparoscopic adjustable gastric band (LAGB) to laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (SG). The safety of a 1- versus 2-stage approach to this revision is debated. OBJECTIVES: We examined the safety and efficacy of 1-stage conversion of LAGB to SG at our institution. SETTING: University hospital. METHODS: An institutional database was used to retrospectively identify patients who underwent single-stage LAGB-to-SG conversion between 2010 and 2018. Patients were matched 1:1 for age, sex, and body mass index with primary SG patients during this same period. Primary endpoints were operative time, complication rate, length of hospital say, and weight loss 12 months from surgery. RESULTS: Two-hundred and twenty-nine patients undergoing conversion of LAGB to SG were identified. Median postoperative length of hospital stay was 2 days. Two patients (.8%) developed surgical site infection. One patient (.4%) developed a postoperative myocardial infarction. There were 4 total readmissions (1.7%) and 1 reoperation within 30 days (.4%). There were no statistically significant differences in 30-day complication rates between groups. Weight loss at 12 months was significantly different: Median body mass index loss for conversion patients was 5.1 kg/m2 compared with 8.85 kg/m2 for patients in the primary SG group (P < .0001). CONCLUSION: Single-stage conversion of LAGB to SG is safe and effective. Patients may not experience the same extent of weight loss as those with primary SG. Our findings represent the largest single-institutional experience to date and support a 1-stage approach whenever feasible.

BACKGROUND: Excessive use of social media is increasingly being recognized as a source of technological addiction in young people globally. OBJECTIVE: The aim of this study is to assess social media addiction in medical students using a self-designed questionnaire. MATERIALS AND METHODS: We collected data from undergraduate medical students (MBBS) in Delhi, India using a self-administered 20-item social media addiction questionnaire (SMAQ) to measure addiction-like behavior, and the Pittsburgh Sleep Quality Index (PSQI) to assess sleep quality. RESULTS: We enrolled 264 (62.3%) male and 160 (37.7%) female participants of mean (standard deviation) age 19.83 (1.6) years. The Cronbach's alpha of the SMAQ was 0.879. A principal component analysis revealed a 4-component SMAQ structure based on eigenvalue cutoff (>1), loading score >0.3, and inspection of the Scree-plot that explained 54.7% of the total variance. We observed strong loadings of impaired control items on Component 1, decreased alternate pleasure items on Component 2, intense desire items on Component 3, and harmful use items on Component 4. The mean SMAQ score was significantly higher in the students reporting poor sleep quality and older students. CONCLUSION: The SMAQ has acceptable psychometric properties, with higher scores associated with sleep deprivation. A majority of students were unable to reduce their time spent on social media despite wanting to do so, signifying the presence of tolerance and impaired control.
RESUMO
BACKGROUND: Internet gaming disorder (IGD) is emerging as an important source of behavioral addiction in young people globally. OBJECTIVE: The aim of this study was to assess addiction to internet gaming in medical students using a self designed research instrument. MATERIALS AND METHODS: We conducted a cross-sectional study and enrolled 264 male and 160 female MBBS students (n = 424) in Delhi, India. The study instruments included: a 2-item Internet gaming screening questionnaire (IGSQ), a 14-item self-designed Internet gaming addiction scale (IGAS) to measure addiction-like behavior associated with multiplayer Internet gaming, and the Pittsburgh Sleep Quality Index to measure sleep quality. RESULTS: After preliminary screening, 91 male and 6 female participants were found to be multiplayer Internet gamers, and were further assessed using the 14-item IGAS. The Cronbach's alpha of the IGAS was 0.879. Principal component analysis revealed a three-component IGAS structure based on eigenvalue cutoff (>1), loading score >0.4, and inspection of the scree-plot that explained 66.71% of the total variance. The IGAS score and the average weekly gaming time of the participants showed a moderate positive correlation (r = 0.45, P < 0.001). Only 17 (4.0%) participants reported agreement/strong agreement across ≥5 domains of addiction. The mean (standard deviation) IGAS score was significantly higher in the participants reporting poor sleep quality (PQSI > 6) (P = 0.047). CONCLUSION: IGD has low prevalence among medical students, and the problem is negligible among female students. The 14-item IGAS, in conjunction with the 2-item IGSQ, are reliable and valid tools for the assessment of IGD.
RESUMO
Choking on small parts remains one of the leading causes of death and injury in infants and toddlers. The current method of testing for small parts, created by the Consumer Product Safety Commission (CPSC), has become outdated and has yet to be changed despite the many deaths and injuries of children. The method uses a device called the small parts test fixture (SPTF) that is supposed to mimic the size of a fully expanded throat of a toddler. If a product does not fit inside the cavity of the SPTF, then it is deemed safe to play with because it "will not fit" in the esophagus of a child. The present study obtains a dataset of products recalled by the CPSC within the last twelve years due to choking hazards/incidents and discovers that a noteworthy amount of the children's products have parts that are larger than the fixture size and are still capable of causing choking. This study indicates that a larger SPTF size must be implemented by the CPSC in order to prevent future choking incidents on small parts.
