Saltwater intrusion in the coastal areas of Bangladesh is a prevalent phenomenon. However, it is not conducive to activities such as irrigation, navigation, fish spawning and shelter, and industrial usage. The present study analyzed 45 water samples collected from 15 locations in coastal areas during three seasons: monsoon, pre-monsoon, and post-monsoon. The aim was to comprehend the seasonal variation in physicochemical parameters, including water temperature, pH, electrical conductivity (EC), salinity, total dissolved solids (TDS), hardness, and concentrations of Na+, K+, Mg2+, Ca2+, Fe2+, HCO3-, PO43-, SO42-, and Cl-. Additionally, parameters essential for agriculture, such as soluble sodium percentage (SSP), sodium absorption ratio (SAR), magnesium absorption ratio (MAR), residual sodium carbonate (RSC), Kelly's ratio (KR), and permeability index (PI), were examined. Their respective values were found to be 63%, 16.83 mg/L, 34.92 mg/L, 145.44 mg/L, 1.28 mg/L, and 89.29%. The integrated water quality index was determined using entropy theory and principal component analysis (PCA). The resulting entropy water quality index (EWQI) and SAR of 49.56% and 63%, respectively, indicated that the samples are suitable for drinking but unsuitable for irrigation. These findings can assist policymakers in implementing the Bangladesh Deltaplan-2100, focusing on sustainable land management, fish cultivation, agricultural production, environmental preservation, water resource management, and environmental protection in the deltaic areas of Bangladesh. This research contributes to a deeper understanding of seasonal variations in the hydrochemistry and water quality of coastal rivers, aiding in the comprehension of salinity intrusion origins, mechanisms, and causes.

Nanocellulose, a promising green material derived from various bio-sources, has potentiality on and off-site in the agricultural sector. Due to its special qualities, which include high strength, hydrophilicity, and biocompatibility, it is a material that may be used in a variety of industries, especially agriculture. This review explores in this article production processes, post-processing procedures, and uses of nanocellulose in soil fertility increment and sustainable agriculture. A variety of plant materials, agricultural waste, and even microbes can be used to isolate nanocellulose. Nanocellulose is produced using both top-down and bottom-up methods, each of which has benefits and limitations of its own. It can be applied as nano-biofertilizer in agriculture to enhance beneficial microbial activity, increase nutrient availability, and improve soil health. Moreover, nanocellulose can be used in fertilizer and pesticide formulations with controlled releases to increase efficacy and lessen environmental effects. Innovative approaches to sustainable agriculture are provided by nanocellulose technologies, which also support the UN's Sustainable Development Goals (SDGs), especially those pertaining to eradicating hunger and encouraging responsible consumption. Nanocellulose promotes climate action and ecosystem preservation by increasing resource efficiency and decreasing dependency on hazardous chemicals, ultimately leading to the development of a circular bioeconomy. Nonetheless, there are still issues with the high cost of production and the energy-intensive isolation procedures. Despite its various potentialities, challenges such as high production costs, environmental concerns, and regulatory issues must be addressed for nanocellulose to be widely adopted and effectively integrated into farming practices.

The existence of heavy metal pollutants in fish within aquatic ecosystems presents a threat to human health due to trophic shift. This research sought to identify the concentrations of cadmium (Cd), arsenic (As), copper (Cu), lead (Pb), and chromium (Cr) in two economically significant cultured fish species, pangus (Pangasius hypophthalmus) and catla (Labeo catla), which were sourced from key fish markets in Khulna, Bangladesh. Nevertheless, there has been a scarcity of studies addressing the metal concentrations in these species within this region. To evaluate the levels of trace elements, atomic absorption spectrophotometry (AAS) was employed following the acid digestion of the samples. The concentrations of Cd, As, Cu, Pb, and Cr were observed as 0.372, 0.232, 0.741, 0.758, and 1.356 mg/kg in pangus and 0.395, 0.297, 1.175, 0.616, and 0.959 mg/kg in catla fish, respectively. The concentrations of Pb and Cd exceeded the maximum permissible limits established by the FAO and WHO. Apart from Cu, the estimated daily intakes (EDI) for both seasons and age groups exceeded the recommended daily allowance (RDA), indicating that other trace elements could be detrimental to human health. In contrast, the calculated hazard index (HI) and total hazard quotient (THQ) remained below 1, suggesting that the fish examined would not pose health risks to adults but the HI value for children surpassed the acceptable limit. Moreover, Cd (for adult group) and Cd and Cr (for children group) surpassed the acceptable range for carcinogenic risk (CR), and the total carcinogenic risk (TCR) exceeded the permissible limit for both groups. This study concluded that studied fishes may represent a health risk for consumers, underscoring the necessity for ongoing monitoring of trace elements in other fish species within that catchment area.

BACKGROUND: In patients with suspected myocardial infarction, the 0/1 h pathway (blood draws at 0 h and 1 h) is recommended in current guidelines for early risk stratification. However, individual trials used different safety outcomes, and efficacy outcomes were inconclusive or not assessed. We conducted a systematic review and individual participant data meta-analysis of all randomised controlled trials to synthesise the totality of the evidence, assess heterogeneity across trials, and evaluate clinically relevant outcomes using harmonised definitions across trials.
METHODS: In this systematic review and individual participant data meta-analysis, we searched PubMed, Cochrane Central Register of Controlled Trials, Scopus, and the International Clinical Trials Registry Platform from inception to July 6, 2026, without language restrictions, for randomised trials comparing the safety and efficacy of 0/1 h versus 0/3 h pathways (blood draws at 0 h and 3 h, ie, standard care). Individual participant data were obtained and outcome definitions were harmonised. The primary analysis used a two-stage random-effects meta-analysis. After receipt of the individual participant data but before data harmonisation or analysis, the primary safety outcome was refined to a composite of all-cause death or new type 1 myocardial infarction within 30 days, from the originally specified composite of all-cause death or any new myocardial infarction. The primary efficacy outcomes were emergency department length of stay and direct discharge from the emergency department. This meta-analysis is registered with PROSPERO (CRD420261383452).
FINDINGS: Our systematic review identified five randomised trials, all of which provided individual participant data. Among these, the definition of the primary safety outcome varied, and in four trials emergency department length of stay was not reported for the whole analysis population. We included 110 933 patient presentations (55 489 managed with the 0/1 h pathway and 55 444 managed with the 0/3 h pathway). Within 30 days, all-cause death or new type 1 myocardial infarction occurred in 446 patient presentations (0·8%) with the 0/1 h pathway versus 562 patient presentations (1·0%) with the 0/3 h pathway (random-effects pooled odds ratio [OR] 0·83 [95% CI 0·45-1·53]; I2=62·9%; τ2=0·143). Emergency department length of stay was 314 min (IQR 211-481) in the 0/1 h pathway group versus 308 min (209-453) in the 0/3 h pathway group (random-effects pooled geometric mean ratio 1·03 [95% CI 0·85-1·25]; I2=99·2%; τ2=0·024). Direct discharge from the emergency department occurred in 37 190 patient presentations (67·0%) with the 0/1 h pathway versus 36 485 patient presentations (65·8%) with the 0/3 h pathway (random-effects pooled OR 1·31 [95% CI 0·79-2·16]; I2=97·8%; τ2=0·156).
INTERPRETATION: Across the available randomised trials, short-term adverse event rates were low with both pathways, but the pooled safety estimate remained imprecise. On average, earlier cardiac troponin retesting did not reduce emergency department length of stay or clearly increase direct discharge, and substantial between-study heterogeneity indicates that treatment effects might not translate uniformly across health-care systems. For hospitals considering transitioning from a 0/3 h to a 0/1 h pathway, implementation decisions should take broader diagnostic and organisational considerations into account.
