Graphical abstract .Rice (Oryza sativa L.) is the main food crop cultivated in Sri Lanka, and different varieties of rice are grown under different conditions of fertilizer application throughout the country. Since the consumption of rice is extremely high, it is considered as the major dietary source for macro- and micro-nutrients and also for toxic trace elements. The main objective of this study was to investigate and compare trace element levels in native and improved rice varieties that were grown under both organic and inorganic chemical fertilizers and also under unfertilized conditions. Rice grains were collected from a plot experiment with seven native and seven improved rice varieties that were treated with organic and inorganic fertilizers. Contents of macro-nutrients (Na, K, Ca and Mg) and trace elements (Cd, As, Pb, Cr, Mn, Co, Ni, Cu, Zn and Ba) in rice grains were measured by inductively coupled plasma mass spectrometry. The results indicated that rice cultivated using inorganic fertilizers showed the highest mean trace element contents while organic fertilizer-treated improved rice varieties showed the lowest Cd (0.10 mg/kg) which is lower than the maximum permissible level (0.2 μg g-1). The highest mean value of Cd (0.32 mg/kg) was recorded in native rice varieties grown in plots with chemical fertilizer applications. However, the As content in rice samples collected from all treatment conditions indicated contents lower than the maximum permissible level. Rice cultivated in plots that were treated with chemical fertilizer showed the highest mean macro-nutrient contents.A rapid and low-cost method for determination of total mercury (THg) in cat food was developed based on photochemical vapor generation (PVG) coupled to cold vapor atomic absorption spectrometry (CVAAS). Cat food samples with ingredients based on tuna fish and other seafood were investigated. Organic acid precursor and concentration for radical generation and Hg photoreduction, sample UV irradiation time, and carrier gas flow were optimized. Highest PVG efficiency was achieved using 10% v v-1 formic acid, 4-s UV irradiation time, and a carrier gas flow of 50 mL min-1. The calibration function presented a correlation coefficient of 0.99. Accuracy was confirmed by analysis of Certified Reference Materials with recoveries of 93-110% and relative standard deviation lower than 6%. Under optimized conditions, a procedural detection limit of 0.28 μg kg-1 was obtained. Determination of THg in 10 samples of cat food purchased in local markets revealed a concentration range of 0.035-0.388 mg kg-1. Highest concentrations were found in cat foods. Only one sample presented a concentration close to the regulatory limit of the European Commission Directive. Assuming the estimated daily food intake (EDI) calculated in a range of 0.0021 to 0.023 mg of THg per day per kg body weight, it is concluded that it remains below that considered lethal for cats. The methodology is efficient, simple, low cost, and fit for purpose.Twenty-six major and trace elements, in the seed and the mesocarp of wild and cultivated rosehips from different locations in Serbia, were quantified by means of inductively coupled plasma-atomic emission spectroscopy (ICP-AES). The cultivated rosehip was investigated for the first time. In both wild and cultivated rosehips, the most abundant elements were K and Ca. Among trace elements, Mn (in both seed and mesocarp); Fe (in seeds); and B, Ba, and Sr (in mesocarp) were quantified in the highest concentrations. The higher content of Cu, K, Mn, P, and S in the seed of cultivated rosehip, as well as Ca, Mg, and Sr in the mesocarp of wild rosehip, was observed, both significant at p less then 0.05. Additionally, differences between the seed and the mesocarp of studied rosehip were noticed in the content of B, Cu, Fe, K, Ni, P, S, Sr, and Ti (p less then 0.05). Nutritional assessment revealed that both wild and cultivated rosehips are a valuable source of essential elements (Ca, Cu, K, Mg, Mn, and P). The absence of toxic and potentially toxic elements additionally contributes to the quality of studied Serbian rosehip. A high impact of factors such as variety, location, as well as their interaction on the content of elements in cultivated rosehip mesocarp and seed was observed. Pattern recognition techniques, principal component analysis (PCA), and hierarchical cluster analysis (HCA) were applied in order to provide insight into similarities among the analyzed samples.Objectives To analyse the clinical and molecular spectrum of Lipoprotein Lipase (LPL) deficiency and to highlight the effect of a cost-effective indigenous diet for management of this disorder. Methods This is a single-centre retrospective study. Fifteen patients from 14 kindreds with severe hypertriglyceridemia (more than 1000 mg/dl) were evaluated for a period of 12.5 y at Amrita Institute of Medical Sciences, Kerala, India. Results Thirteen of 15 patients were referred after incidental detection of lipemic plasma, 1/15 had chylothorax in the neonatal period and 1/15 had pancreatitis. The mean age of presentation was 7 mo (ranging from 2 d to 4 y), and 20% of the patients had a positive history of consanguinity. Hepatomegaly (15/15), splenomegaly (9/15) and lipemia retinalis (14/15) were common findings. Lipemia retinalis was a useful non-invasive diagnostic tool. All the patients were subjected to diet modification and followed up at regular intervals. Fourteen of 15 complied with the diet, resulting in a dramatic improvement in the fasting lipid profile; only 1/15 developed pancreatitis. Genetic screening analysis was offered to 14/15 patients (1/15 was lost to follow-up); six different variants were identified, of which two were novel variants. find more Conclusions Lipemic serum, chylothorax and recurrent pancreatitis in children should raise the suspicion of Lipoprotein Lipase deficiency. Early diagnosis and prompt initiation of a stringent fat-restricted diet are the keys to success for the management of LPL deficiency and prevention of pancreatitis.Objective To study the dynamic change of peripheral lymphocyte subsets and its clinical value in children with infectious mononucleosis (IM). Methods Thirty-six pediatric patients with IM, 19 children with IM-like symptoms but lacking the serological pattern compatible with EB virus infection, and 33 healthy children were enrolled. The changes of peripheral lymphocyte subsets were detected by flow cytometry on admission and on the fifth day of antiviral treatment, respectively. Indicators of liver function and routine blood count were also detected. Besides, the receiver operating characteristic (ROC) curve and the correlation of related indicators was analyzed. Results When IM patients were admitted, the frequency and absolute number of T, CD4-CD8+T, and CD4+CD8+T (DPT) cells were significantly increased while B cells were decreased; the frequency of CD4+CD8-T cells were decreased, but its absolute number did not change significantly; the frequency of NK cells decreased, but its absolute number increased. The absolute number of CD4-CD8+T most significantly positively correlated with serum lactate dehydrogenase (LDH) concentration which could reflect the severity of IM patients. After short-term treatment with acyclovir, elevated lymphocytes decreased, but only DPT-cell frequency and NK-cell absolute number were recovering towards normal. The ROC curve suggested that the frequency of B cells has better diagnostic value for IM in pediatric patients compared to other lymphocyte subsets. Conclusions Peripheral lymphocyte subsets are closely related to the condition of children with IM, and each subset plays a relatively different role in the diagnosis and evaluation of IM.Objectives To examine a cohort of children and adolescents quarantined during Coronavirus disease 2019 outbreak in India and to describe their understanding of, compliance with and the psychological impact of quarantine experience. Methods One hundred twenty one children and adolescents along with their parents were interviewed regarding their compliance and psychological distress during the quarantine period. A comparable data was also obtained from 131 children and adolescents who were not quarantined. Results Most of the children and adolescents were non-compliant as compliance with all requirements was low (7.43%), though compliance with community protective measures (17.35%) was better than compliance with household protective measures (10.71%). Quarantined children and adolescents experienced greater psychological distress than non-quarantined children and adolescents (p ˂0.001). Worry (68.59%), helplessness (66.11%) and fear (61.98%) were the most common feelings experienced under quarantine. Conclusions The low compliance with quarantine requirements as seen in this study raises a serious concern about the effectiveness of quarantine as a preventive measure of disease transmission. Compliance and mental health problems can be improved by providing adequate financial support and enhanced knowledge about pandemic planning.Introduction The lateral lumbar interbody fusion (LLIF) is a safe and effective technique to treat a vast range of lumbar disorders. However, the technique is also burdened by some problems. A new approach to the lateral lumbar interbody fusion was devised to solve or reduce some of the problems regarding the lateral approach. Its principal difference from the standard LLIF relies on positioning the patient in a prone decubitus, which might lead to an increase in the intradiscal lordosis. Methods A retrospective, multicentric, non-randomized study to evaluate segmental and regional lordosis following prone transpsoas (PTP) approach to LLIF. All patients undergoing prone transpsoas surgery at the involved institutions were included. Patients with low-quality images not allowing the measurements of the required spinopelvic parameters were excluded. Measurements included pre- and postoperative index-level segmental lordosis, lumbar lordosis, pelvic incidence, and pelvic tilt. link2 Results Thirty-two (32) patients were included in the study, in which 23 underwent single-level, six (6) underwent two-level, Two (2) underwent three-level, and one underwent four-level PTP. Mean index level segmental lordosis increased from 8.7° to 14.8°(p less then 0.001); lumbar lordosis (L1-S1) increased from 42.1° to 45.8° (p = 0.11), although after excluding an outlier value L1-S1 lordosis results were 41.9° pre-op to 46.7° post-op (p = 0.003). Twenty-two (22) patients had a pre-op PI-LL mismatch of 10° or more, while at the postoperative visit, only 12 patients had a mismatch outside of 10° (p = 0.01). Conclusion The prone transpsoas technique is feasible and is associated with a significant gain of segmental lordosis and correction of spinopelvic alignment parameters.Purpose On average, 56% of patients report a clinically relevant reduction in pain after lumbar spinal fusion (LSF). Preoperatively identifying which patient will benefit from LSF is paramount to improve clinical decision making, expectation management and treatment selection. Therefore, this multicentre study aimed to develop and validate a clinical prediction tool for a clinically relevant reduction in pain 1 to 2 years after elective LSF. Methods The outcomes were defined as a clinically relevant reduction in predominant (worst reported pain in back or legs) pain 1 to 2 years after LSF. Patient-reported outcome measures and patient characteristics from 202 patients were used to develop a prediction model by logistic regression. link3 Data from 251 patients were used to validate the model. Results Nonsmokers (odds ratio = 0.41 [95% confidence interval = 0.19-0.87]), with lower Body Mass Index (0.93 [0.85-1.01]), shorter pain duration (0.49 [0.20-1.19]), lower American Society of Anaesthesiologists score (4.82 [1.
