Effects of water shortage on food legume crops

The clamor for agricultural resources is being pushed up by global climatic change and population growth. Such consequences are huge challenges to food security, wreaking havoc on the agroecosystem and causing biotic and abiotic stresses in plants, which in turn cause metabolic and physiological problems. Food legume crops contribute to food security in underdeveloped countries by playing an essential role in conservation farming methods. Drought has, nevertheless, exhibited a negative impact on productivity in many parts of the world. While water shortage is a significant abiotic barrier to legume crop output, drought impacts differ depending on drought timing, agro-climatic area, soil texture, and legume species. To resolve these concerns, we gathered data from the recent publications that revealed drought-induced changes in the production of monoculture legumes in field circumstances and examined it using meta-analysis approaches. Research findings revealed that the water cut’s quantity was strongly associated with a decrease in yield. However, the magnitude of the effect differed depending on the phenological stage of the drought and legume species. The legumes such as groundnut and lentil exhibited the lowest yield reductions (31.2% and 19.6% for groundnut and lentil, accordingly), however, the biggest yield drop (39.8%) facing the maximum water reduction was for faba bean

Trypsin-based diet for the growth indices of Spanish mackerel

To protect the sustainability of the aquaculture industry, fishmeal is being replaced with alternative feed ingredients such as plant-based protein components. However, most plant-based feedstuffs contain a wide array of anti-nutritional factors. These factors can potentially hinder nutrient consumption, which in turn can interfere with fish health and performance. Protease enzyme supplements can reverse the impacts of anti-nutritional factors and enhance fish growth. This study aimed to incorporate the trypsin enzyme into the food of Spanish mackerel and explore its effects on growth factors, body composition, and blood biochemical parameters. This study was a fully-randomized experiment with three treatments and three replications. This experiment was carried out as a completely randomized design with three treatments and three replications, and the trypsin enzyme was added to the fish diet at different levels: 0%, 0.015%, and 0.025%. For a timeframe of 60 days, the fish were given experimental diets. The growth indices considered were: specific growth rate (SGR), protein efficiency ratio (PER), condition factor (CF), feed conversion ratio (FCR), weight gain percentage (WGP), and hepatic steatosis index (HSI). The results showed that FCR, PER, SGR, and WGP at enzyme levels of 0.015% and 0.025% were substantially different from the control group

Global variation in postoperative mortality and complications after cancer surgery: a multicentre, prospective cohort study in 82 countries

© 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.

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

© 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.
