Brick kiln exhaust when deposited can hamper the nutritional status of the agricultural soils and crops. To study the impact, soil and associated plant samples were collected from the vicinity of a brick kiln cluster in Chattogram, Bangladesh. The soil contamination was evaluated by heavy metal indices. Agricultural soils close to the brick kiln area were very strongly acid to slightly acid. Organic carbon, total nitrogen and available phosphorus content of the agriculture soils near brick kiln cluster were 0.35% to 1.01%, 0.10 to 0.24% and 2.21 to 13.48 mg kg-1 respectively and the significant different mean value of 0.70%, 0.22% and 14.65 mg kg-1 respectively in the reference soil. The nutritional status of sampling sites was lower than the previously reported data. The nutrition status of the plants was at an optimum level as regular fertilizer application was practiced but showed an irregular pattern along with all the soil parameters and heavy metal indices. The contamination factor (Cd), potential ecological risk index (PER) and geo-accumulation index (Igeo) demonstrated that the agricultural soils in the vicinity of the brick kiln cluster were moderately- to highly-polluted. This indicates the deterioration of soil quality by uncontrolled brick kiln operation.

The study attempted to assess the impacts of the brick kilns emissions on the farm soil in and around the kiln areas. A total of 72 representative farm soil samples were collected from 12 selected brick kiln clusters in Rajshahi and Gazipur Districts of Bangladesh, covering two years (September 2015 to August 2017). The collected samples were analyzed using standard methods. The pH and organic matter content in the farm soil samples were found to be very low. The farm soil parameters such as pH, organic matter, and soil texture were found in critical conditions. Among all of the heavy metals, only Cr exceeded the permissible standard of some soil samples. The concentration of Cr ion varied from 9.50 to 52.77 and 16.54 to 70.13 ppm in Rajshahi and Gazipur Districts, respectively indicated the chance of metal contamination in plants. The study results showed that the values of contamination factor (Cif) and ecological risk factor (Eir) in the selected farm soil of Rajshahi and Gazipur Districts existed in the order of Cd > As > Cr > Pb > Zn and Cd > As > Pb > Cr > Zn, respectively. The study results also showed that the pollution load index and risk index values were lower than 1 and 150, respectively, at all sampling locations indicating lower pollution and risk from heavy metals in the areas. The study observed that continuous brick production over the periods degraded topsoil fertility and reduced agricultural productivity.

Abstract Background: Distal radius fractures (DRF) are common in the elderly and are typically caused falls. Malnutrition has also been identified as a poor prognostic factor in elderly patients with fractures. However, the relationship between nutritional status and subsequent falls and functional prognosis for DRF in the elderly is not clear. The aim of the present study was to investigate the association between nutritional status and functional prognosis in elderly patients with DRF. Methods: Study participants included 229 outpatients who required surgical treatment for DRF. The patients’ clinical information, including age, sex, body mass index, bone mineral density, Geriatric Nutritional Risk Index (GNRI), total number of drugs being treated with on admission, use of drugs for osteoporosis, comorbidity severity, the Barthel Index (BI), presence of subsequent falls, fracture type, postoperative follow-up period, and Mayo wrist score was reviewed. Subjects were further divided into two groups according to their GNRI: the malnutrition group and the normal group. Propensity score matching was used to confirm factors affecting the BI and subsequent falls. Results: Thirty-one patients (13.5%) presented with malnutrition before surgery for DRF. According to multiple liner regression analysis, the GNRI positively affected the efficiency of the BI (β = 0.392, 95% confidence interval [CI], 0.001 to 0.351, p = 0.039). Furthermore, on logistic regression analysis, subsequent falls were associated with serum albumin levels (odds ratio = 0.033, 95% CI, 0.002 to 0.477, p = 0.012). Conclusion: Malnutrition impaired improvement of activities of daily living (ADL) and increased the incidence of subsequent falls. Improvement of nutritional status before DRF surgery may further improve ADL and prevent falls.

Objective To determine the impact of nutritional status on peritonitis in patients on continuous ambulatory peritoneal dialysis (CAPD) in a developing country. Methods 56 patients with end-stage renal disease on CAPD were randomly selected for this study. These patients were assessed for nutritional status and peritonitis episodes. Nutritional parameters were assessed by anthropometry, diet, body mass index (BMI), Nutritional Risk Index (NRI), serum albumin level, and Subjective Global Assessment (SGA). Based on SGA, patients were categorized into either group 1 (malnutrition, n = 31) or group 2 (normal nutritional status, n = 25). Peritonitis was considered the primary outcome and was compared between the two groups. Results Demographic profiles, Kt/V, creatinine clearance, and mean follow-up of the two groups were similar. Number of peritonitis episodes was significantly higher in patients with malnutrition (25/31) compared to patients with normal nutritional status (4/25) ( p = 0.001). Mean peritonitis rate per patient per year was also significantly higher in patients with malnutrition (0.99 ± 1.07) compared to patients with normal nutritional status (0.18 ± 0.42) ( p = 0.007). On univariate analysis, malnutrition based on SGA ( p = 0.009), NRI ( p = 0.02), serum albumin level ( p = 0.005), and calorie intake ( p = 0.006) was a significant predictor of peritonitis. On multivariate Cox regression analysis, only SGA ( p = 0.001, odds ratio 0.08, 95% confidence interval 0.02 – 0.36) was found to be a significant predictor of peritonitis. On general linear model, the observed power of prediction of peritonitis was 0.96 based on SGA. On Kaplan–Meier survival analysis, peritonitis-free survival in patients with normal nutrition (42 months) was significantly higher compared to patients with malnutrition (21 months) based on SGA (log rank p = 0.003). Conclusion We conclude that peritonitis rate is high in patients with malnutrition and that malnutrition indices, especially SGA, can predict the peritonitis rate in CAPD patients.

101 Background: Preoperative malnutrition worsens morbidity and survival, however the role of post-gastrectomy nutritional status in survival remains unclear. The nutrition risk index (NRI) described by Buzby is a scoring system for identifying patients with preoperative poor nutrition status. However, the significance of NRI in evaluating post-gastrectomy nutritional status has not yet been established. Therefore, we aimed to clarify whether malnutrition condition evaluated by NRI after surgery can be a predictive factor for long-term survival in patients with gastric cancer. Methods: Pathological stage I, II, and III gastric cancer patients who underwent curative gastrectomy between 2002 and 2013 were included in this study. NRI was calculated using the following formula; (1.489 × serum albumin, g/L) + (41.7 × current weight/usual weight), and we defined an NRI of above 97.5 as normal nutrition (N group) and 97.5 or below as malnutrition (M group). NRI was evaluated before gastrectomy and 1, 3 and 12 months after gastrectomy. The correlations of clinicopathological characteristics, surgical treatment and overall survival, with nutritional status were retrospectively evaluated. Results: A total of 2552 patients were enrolled. There were significant differences in age, sex, body mass index, performance status, co-morbidity, histology and malignant stage between the groups before gastrectomy. Overall survival in the M group was significantly poorer, both before gastrectomy (adjusted HR 1.31; p < 0.001) and at 1 month (adjusted HR 1.52; p < 0.001), 3 months (adjusted HR 1.35; p = 0.004) and 12 months (adjusted HR 1.37; p = 0.006) after gastrectomy. In multivariate analysis, low NRI at 12 months after gastrectomy, age, co-morbidity and malignant stage were independently associated with overall survival. Overall survival in patients who fulfilled preoperative normal nutrition status criteria was also significantly poorer at 12 months after gastrectomy in the M group. Conclusions: Malnutrition after surgery, as well as before surgery, had a significant impact on overall survival. Postoperative nutritional statue evaluated by NRI may be a good predictive marker for long-term survival.

Improvement of nutritional status before DRF surgery may further improve ADL and prevent falls.

Good nutrition is the foundation of human well-being that leads to better health, effective engagement of the workforce, and productive lifestyle, resulting in higher income and an integrated development trajectory. This paper attempts to comprehend the impact of climate vulnerability on household nutrition status through agriculture production systems in Odisha, India. This study using secondary data estimates a composite index of climate vulnerability on the agriculture ecosystem in Odisha at the district scale. Results suggest that among all the districts in Odisha, Bhadrak (0.193) is the most vulnerable district followed by Sonepur (0.191) and Baudh (0.190). On the other hand, Mayurbhanj (0.099) is the least vulnerable district followed by Ganjam (0.103) and Sundargarh (0.105). The fi ndings also suggest that there is a wide variation in vulnerability indicators among the districts in Odisha (0.099 – the lowest district value vs. 0.193 – the highest). The results of multivariate analysis evince that in households (both women and children) nutritional status, the composite value of “climate vulnerability” has a greater role in predicting the predictors in Odisha through the agriculture production system. The climate vulnerability has a positive and signifi cant relationship with forest area (r=0.403*), gross cropped area (r=0.489**), percent of scheduled caste population (r=0.510**), percent of urban area (r=0.427*), and per-capita income (r=0.712**). The fi ndings also signify that district-wise gross cropped area (t=3.01), average annual rainfall (t=4.05), area under irrigation (t=3.36), cropping intensity (t=3.60), and forest areas (t=1.81) play a more predictive role to determine the household nutritional status along with socioeconomic and health factors such as per-capita income (t=1.8), urbanization (t=1.91), and women’s anemic status (t=2.74). Drawing inferences from the empirical evidence, the study suggests that climate vulnerability has a much greater role in influencing household nutrition status, particularly with women and child nutrition through the agriculture production system. Appropriate policy level measures for climate-sensitive and adaptive action are the need of the hour to make agriculture production ecosystem contributes positively to nutrition status.

Heavy metal pollution that results from electronic waste (e-waste) recycling activities has severe ecological environmental toxicity impacts on recycling areas. The distribution of heavy metals and the impact on the bacteria in these areas have received much attention. However, the diversity and composition of the microbial communities and the characteristics of heavy metal resistance genes (HMRGs) in the river sediments after long-term e-waste contamination still remain unclear. In this study, eight river sediment samples along a river in a recycling area were studied for the heavy metal concentration and the microbial community composition. The microbial community consisted of 13 phyla including Firmicutes (ranging from 10.45 to 36.63%), Proteobacteria (11.76 to 32.59%), Actinobacteria (14.81 to 27.45%), and unclassified bacteria. The abundance of Firmicutes increased along with the level of contaminants, while Actinobacteria decreased. A canonical correspondence analysis (CCA) showed that the concentration of mercury was significantly correlated with the microbial community and species distribution, which agreed with an analysis of the potential ecological risk index. Moreover, manually curated HMRGs were established, and the HMRG analysis results according to Illumina high-throughput sequencing showed that the abundance of HMRGs was positively related to the level of contamination, demonstrating a variety of resistance mechanisms to adapt, accommodate, and live under heavy metal-contaminated conditions. These findings increase the understanding of the changes in microbial communities in e-waste recycling areas and extend our knowledge of the HMRGs involved in the recovery of the ecological environment.

Abstract This research aimed to assess the ecological status of the Hrazdan river section flowing through Yerevan. The distribution of toxic elements (Cr, V, As, Zn, Cu, Ni, Co, Mn, Pb, Ti, Mo, Fe, Ba), the bottom sediments pollution level and ecological risks, were assessed employing the contamination factor (CF), enrichment factor (EF), the potential ecological risk index (RI) and geoaccumulation index (Igeo). On sampling sites, water quality parameters (turbidity, DO, conductivity (EC), salinity, TDS, pH, T°C) were measured, as well. The correlation analysis revealed a significant correlation between Zn - Cu, Pb; Cu - Pb, Mo; Co - Fe, Ti pointing out the similar sources and origination of these elements. The results have indicated that the content of the studied elements in the Hrazdan bottom sediments exceed the background content in urban soils, which is due to a set of geological and anthropogenic factors. High contents of elements were determined on sampling sites spatially confined to the residential and industrial areas. According to EF and Igeo data, the priority bottom sediment contaminants are As, Pb, Mo, Zn, V, Cu. The RI value varies from 195.9 to 316.3 with the mean of 245.9 which corresponds to the moderate-level ecological risk. On the whole, a moderate (77.8%) and considerable (22.2%) ecological risk was revealed. An essential source of Pb, Cu, Zn, Mo contents was itentified to be the surface runoffs in urban environment.

The aim of these investigations was to determine the impact of heavy metals bound with deposited particulate matter (PM) on contamination degree and related toxicological effects by calculating enrichment indices, namely, the geo-accumulation index (Igeo), contamination factor (CF), and enrichment factor (EF), as well as the ecological risk index (ERI) and modified hazard quotient (mHQ). Calculations were made based on the selected element concentrations determined in deposited PM samples in Krakow. The results of the investigations revealed that deposited PM was enriched in heavy metals. As Igeo provides information on the level of metal accumulation, it was found that deposited PM was practically uncontaminated with Be, Cd, and Tl (class 0) but heavily to extremely contaminated (class 5) with Co and Sn and extremely contaminated (class 6) with As, Ba, Cr, Cu, Li, Mn, Ni, Pb, Sr, Ti, V, and Zn. On the other hand, the calculated values of CF revealed very high contamination of deposited PM with Cd and Zn, considerable contamination with Sn, Pb, and As, and moderate contamination with Cu and Li. Values of calculated EF revealed that among the investigated elements, only Zn originated from anthropogenic sources. For Cd, a small influence of anthropogenic sources was observed. For Pb and Sn, non-crustal sources of emission were expected. The calculated ERI values indicated potential ecological risk levels that were very high for Cd and considerable for Zn, as well as low potential ecological risk for As, Co, Cr, Cu, Ni, Pb, and Tl. Moreover, the calculated mHQ values of severity of contamination were extreme for Zn, considerable for Cr, and moderate for As, Cu, and Pb. The analysis revealed that the impact of atmospheric and re-suspended PM on inhabitants constitutes a complex effect of a mixture of heavy metals simultaneously affecting human health.
