Imidacloprid-induced mortality, histopathology and biochemical impairments in the larvae of oriental latrine fly (Chrysomya megacephala).

The concentration-mortality response of third instar larvae of Chrysomya megacephala (Diptera: Calliphoridae) to a synthetic insecticide, imidacloprid, and its impact on histopathological, histochemical, and biochemical parameters were determined in laboratory assays. Larvae displayed a concentration and time-dependent mortality response for the insecticide. Histopathological studies exhibited quite noticeable modifications in the epithelial cells, peritrophic membrane, basement membrane and muscular layer of the larval midgut. The ultrastructural analysis demonstrated alterations in nuclei, lipid spheres, microvilli, mitochondria, rough endoplasmic reticulum and lysosomes. In addition, histochemical tests on the midgut were performed, which revealed a strong reaction for proteins and carbohydrates in the control group and a weak reaction in the group exposed to imidacloprid in a dose and time-dependent manner. Imidacloprid also caused a significant reduction in the total midgut content of carbohydrates, proteins, lipids and cholesterol. Larvae treated with imidacloprid also showed a reduction in the activities of acid and alkaline phosphatases at all concentrations compared to untreated larvae.

Effect of nutritional parameters on microbial production of L-Asparaginase by novel Brevibacillus borstelensis ML12.

L-Asparaginase owes considerable significance in food and pharmaceutical applications. L-Asparaginase is an antineoplastic enzyme that finds application in the treatment of Acute Lymphoblastic Leukemia (ALL) and in mitigating acrylamide (a potent carcinogen) production during baking. In this study, we aimed to optimize nutritional parameters that are significant in initiating and regulating a bioprocess system in order to maximize enzyme production from a novel isolated bacterial species Brevibacillus borstelensis ML12 so the high-yielding enzyme producers can be selected and utilized for better efficacy of this commercially viable enzyme in pharmaceutical field, food industry, in biosensors and as an antioxidant growth kinetics study of the organism was performed and the maximum specific growth rate µo (min-1) and Monod half saturation constant Ks for L-Asparagine came out to be µo = 0.0189 min-1 and Ks = 2.44 mM, respectively at 0.04 M asparagine concentration and 37 °C. Effect of different nutritional parameters like carbohydrates, organic and inorganic nitrogen sources, L-Asparagine, minerals, surfactants and bile were performed. Maximum L-Asparaginase production occurred at 0.01% dextrose, 20 g L-1 L-Asparagine, 10 mM cobalt chloride, 0.1% Tween 80 and 1% bile concentrations (237.319 IU mL-1).

Protein restriction during puberty alters nutritional parameters and affects ovarian and uterine histomorphometry in adulthood in rats.

In a large part of the population inefficient ingestion of proteins, whether for cultural, aesthetic or economic reasons, is a global concern. Low-protein diets can cause severe functional complications, mainly during the development and maturation of organs and systems, including the female reproductive system. The present study investigated the effect of nutritional protein restriction during puberty on the oestrous cycle and expression of sex steroid receptors (AR, ERα e ERß) in ovarian and uterine tissues of adult rats. Protein restriction promoted lower body weight gain, feed efficiency and higher caloric intake. There was an increase in the oestrus phase arrest without changing the total length of the oestrous cycle. The consumption of low-protein diet also reduced the thickness of the uterine endometrium (uterine epithelium and endometrial stroma) in addition to increasing the number of primary and atretic follicles in the ovaries. Furthermore, the low-protein diet reduced the levels of androgen receptor (AR) and increased the oestrogen receptor ß (ERß) in the ovary, while no significant changes were observed in the uterus. Our study reinforces the importance of adequate protein intake during puberty, since physiological changes in this developmental period interfere with the histomorphometry of the ovaries and uteri, possibly resulting in impaired folliculogenesis and fertility in the reproductive period.

Biochemical parameters in determination of nutritional status in amyotrophic lateral sclerosis.

OBJECTIVES: Amyotrophic lateral sclerosis (ALS) is a fatal, neurodegenerative disorder without effective treatment. Progressive dysphagia, depression, and hypermetabolism may lead to malnutrition. The aim of the present study was to analyze the potential utility of readily available, relatively inexpensive, and rapid strategy for using laboratory parameters to assess nutritional status of ALS patients. METHODS: This study included 203 patients with ALS. The analysis of inflammatory parameters: C Reactive Protein (CRP), erythrocyte sedimentation rate (ESR), white blood cell count (WBC), lymphocytes number (LN), and fibrinogen concentration (FC) was followed by nutritional markers: serum concentration of albumin (ALB), prealbumin (PALB), transferrin (TRNF), and creatinine (CREA), which were correlated with demographic and clinical parameters: body mass index (BMI), ALS phenotype, disease duration, diagnosis delay, and functional and respiratory assessment. RESULTS: Nearly 20% of patients had biochemical features of inflammation. Among patients without inflammation (n = 163), a decreased serum TRNF concentration was found in 84% of cases, PALB in 39%, ALB in 25%, and CREA in 53%. The median of PALB was the highest in patients with PMA (23.5 mg/dL) and the lowest in PBP (16.6 mg/dL) (p < 0.05). The CREA concentration correlated with the BMI (r = 0.25; p < 0.01), while PALB and TRNF significantly varied depending on the severity of dysphagia. Patients with dysphagia qualified to enteral nutrition showed significantly decreased concentration of PALB, triglycerides, as well as reduced forced vital capacity, BMI, and functional status. CONCLUSIONS: CREA, PALB, ALB, and TNFR are easily accessible, accurate, and low-cost parameters useful in assessment of the nutritional status in ALS.

Influence of nutrient restriction on finishing Morada Nova lambs.

Our objective was to evaluate the effect of 15% crude protein (CP) and total digestible nutrient (TDN) restriction vis-á-vis that recommended by NRC (2007) on feed intake, digestibility, and average daily gain (ADG) of confined Morada Nova lambs. Twenty lambs with 18.8 ± 2.8 kg liveweight were assigned to a randomized 2 × 2 factorial experiment with either early- or late-maturity feed formulation according to "Nutrient Requirements of Small Ruminants" with or without 15% CP and TDN restriction. The early-maturity diet, independent of restriction, resulted in greater dry matter and organic matter intake and increased rumination efficiency and feed conversion. Early-maturity diets also had the greatest nutrient digestibility as well as ADG and total gains. With late-maturity diets, independent of restriction, there were greater CP and TDN digestibilities as well as neutral detergent fiber (NDF) feed efficiency. However, when 15% of nutrients were restricted for late-maturity lamb diets, there was greater NDF intake and greater ether extract digestibility. Unrestricted early-maturity lamb diets was the better diet for confined Morada Nova lambs. Attention should be given to minimum effective NDF consumed and physically effective for this diet formulation. The use of late-maturity diets as recommended by NRC (2007) allows for 15% restriction of CP and TDN in Morada Nova lambs without negative effects on performance. This restriction should be tested in other tropical breeds to determine wider application.

Rapid Determination of Nutritional Parameters of Pasta/Sauce Blends by Handheld Near-Infrared Spectroscopy.

Nowadays, near infrared (NIR) spectroscopy has experienced a rapid progress in miniaturization (instruments < 100 g are presently available), and the price for handheld systems has reached the < $500 level for high lot sizes. Thus, the stage is set for NIR spectroscopy to become the technique of choice for food and beverage testing, not only in industry but also as a consumer application. However, contrary to the (in our opinion) exaggerated claims of some direct-to-consumer companies regarding the performance of their "food scanners" with "cloud evaluation of big data", the present publication will demonstrate realistic analytical data derived from the development of partial least squares (PLS) calibration models for six different nutritional parameters (energy, protein, fat, carbohydrates, sugar, and fiber) based on the NIR spectra of a broad range of different pasta/sauce blends recorded with a handheld instrument. The prediction performance of the PLS calibration models for the individual parameters was double-checked by cross-validation (CV) and test-set validation. The results obtained suggest that in the near future consumers will be able to predict the nutritional parameters of their meals by using handheld NIR spectroscopy under every-day life conditions.

Probiotic mitigates the toxic effects of potassium dichromate in a preclinical study: a randomized controlled trial.

BACKGROUND: The present study aimed to evaluate the nutritional, physiological and biochemical effects of dietary supplementation of an association of probiotic bacteria in rats intoxicated with chromium (VI). Ninety-six male rats, recently weaned, were randomly divided into eight groups (n = 12): Control, DK12, DK24 and DK36 (0, 0.12, 0.24 and 0.36 g kg-1 of K2 Cr2 O7 incorporated in the basal feed, respectively) and groups Prob, DK12 + Prob, DK24 + Prob and DK36 + Prob received a progressive dose of 0, 0.12, 0.24 and 0.36 g kg-1 of K2 Cr2 O7 incorporated in the basal feed and supplemented with 0.02 g kg-1 of an association of probiotic bacteria (Lactobacillus acidophilus, Enterococcus faecium, Bifidobacterium thermophilum and Bifidobacterium longum). RESULTS: After 90 days, we observed significant (P < 0.05) and dose-dependent alterations from incorporation of increasing doses of chromium (VI) related to nutritional, physiological and biochemical parameters. These changes were attenuated (P < 0.05) with probiotic supplementation. CONCLUSION: Supplementation with probiotics in the diet beneficially modified the nutritional and physiological parameters, as well as hepatic, renal, glycemic and lipid profiles, of animals intoxicated with increasing doses of K2 Cr2 O7 . © 2018 Society of Chemical Industry.

Nutritional alterations after very low-calorie diet before bariatric surgery.

INTRODUCTION: There has been an alarming worldwide increase of obese people in recent years. Currently, there is no consensus on whether patients that are scheduled to undergo bariatric surgery should lose weight before the intervention. The objective of this research is to analyse the influence of pre-surgery loss of weight in the nutritional parameters of patients. METHODS: Fifty patients that were scheduled to undergo bariatric surgery followed a very low caloric diet during 4 weeks prior to the surgery. The nutritional parameters were analysed at 3 specific moments: before starting the diet, at the moment of surgery (when the diet was concluded) and one month after the surgery. RESULTS: Average values for hemoglobin, albumina and lymphocytes were kept within the range of normal values at all moments, even though the decrease of those parameters was statistically significant throughout the study (P<.05). By following the very low caloric diet, less than 9.5% of the sample suffered anaemia. CONCLUSIONS: Loss of weight prior to surgery does not have a significant influence in the nutritional parameters of the patient. These results would support the indication of losing weight for patients that are considered candidates for bariatric surgery.

Correlations between changes in intestinal microbiota composition and performance parameters in broiler chickens.

Growing male Cobb broiler chickens were fed on diets supplemented with additives reported as able to influence intestinal microbiota composition. The diets used were a balanced commercial diet (no additive), inulin (20 g/kg), fructose caramel (FC, 20 g/kg) and the garlic derivative PTS-O (propyl propane thiosulfonate, 45 and 90 mg/kg diet). The composition of the intestinal microbiota was analysed by qPCR at different points of the intestinal tract, and a number of nutritional parameters were also determined. The relative amounts of bacteroides (bacteroides/total bacteria) in the ileal contents correlated (p < 0.05) positively with faecal NDF, ADF, hemicellulose and cellulose digestibility. The relative amounts of Escherichia-Shigella (Escherichia-Shigella/total bacteria) in the crop contents correlated (p = 0.05) negatively with weight gain of broilers. Faecal N digestibility correlated (p < 0.05) negatively with total bacteria in the ileal contents of chickens. The relative amounts of Escherichia-Shigella (Escherichia-Shigella/total bacteria) in the caecal contents correlated (p = 0.05) negatively with faecal fat digestibility of broilers. Total bacteria in ileal or caecal contents of growing chickens correlated (p < 0.05) negatively with ileal N digestibility. The results here reported suggest that positive or negative correlations can be found between performance parameters and changes in intestinal microbiota composition of growing broiler chickens.

Nutritional and antinutritional attributes of faba bean (Vicia faba L.) germplasms growing in Bihar, India.

Eleven germplasms of faba bean seeds from four agroclimatic regions of Bihar, India, have been investigated to estimate their nutritional (soluble protein, free amino acids, starch, reducing and non reducing sugar, total soluble sugar) and antinutritional (total extractable phenol and condensed tannin/proanthocyanidin) parameters. These parameters were found in varying concentration in all genotypes studied. The highest concentration of total extractable phenol and proanthocyanidin (condensed tannin) (2.56 and 1.59 % leucocyanidin equivalents respectively on dry matter basis) were found in Samastipur while the lowest from Patna (0.95 and 0.426 % leucocyanidin equivalent on dry matter basis). The different nutritional parameters were also found to be in variable concentration among different germplasms viz. total soluble protein ≈ 20-32 %, free amino acids ≈ 188-348 mg/100 g, starch ≈ 27-33 %, reducing sugars ≈ 85-188 mg/100 g, non reducing sugars ≈ 0.7-1.7 % and total soluble sugars ≈ 0.8-1.9 %.

Levels of supplementation for grazing beef heifers.

The objective of this experiment was to evaluate the effect of providing different levels of a supplement on the nutritional characteristics and productive performance of heifers on pasture during the rainy-dry transition and dry season in Brazil or tropical area. Thirty crossbred heifers with predominance of Zebu breed were used in a completely randomized experimental design. Treatments consisted of a mineral supplement and 0.5, 1.0, 1.5, or 2.0 kg/animal/d of a protein supplement containing 300 g crude protein (CP)/kg of dry matter (DM). In the rainy-dry transition season there was quadratic effect of the protein supplementation (p<0.10) on daily weight gain (DWG). A linear relationship (p<0.10) was found between increasing supplement intake and intakes of DM, organic matter (OM), crude protein (CP), ether extract (EE), non fibrous carbohydrates (NFC) and total digestible nutrients (TDN). Coefficients of apparent digestibility of CP, EE, and NFC increased linearly (p<0.10) with increasing supplement levels, but there was no effect on the DM apparent digestibility (p>0.10); the microbial efficiency (g CPmic/kg TDN) and the relationship of microbial nitrogen flow with nitrogen intake (g/g nitrogen intake) were negative linear profiles. In the dry season, the descriptive pattern least squares means showed a trend of stabilization of DWG from the supply of 0.98 kg of protein supplement; the intakes of DM, OM, CP, EE, NFC, and TDN showed increasing linear relationship (p<0.10) with protein supplement levels; the means of apparent digestibility coefficients of the different dietary fractions presented a linear-response-plateau (LRP); the microbial nitrogen flow (g/d) showed positive linear profile (p<0.10) for supplementation levels. It is concluded that supplementation improves the productive performance of grazing heifers and that 1.0 kg/d of supplement per animal gives the maximum increment of weight gain.

Comparative Analysis of Maize Physico-Chemical Parameters and Mycotoxin Levels in Dual Environments.

Maize (Zea mays L.) stands as a vital staple food globally, holding significant nutritional and economic value. However, its susceptibility to mycotoxin contamination under stressful environmental conditions poses a considerable concern. This study aimed to assess the quality and pasting characteristics of maize varieties across two distinct regions and examine the occurrence of mycotoxins influenced by climatic factors. Five maize varieties were cultivated in triplicate in the Golegã and Coruche regions. The nutritional composition (protein, fat, fiber, ash, starch, and lutein), pasting properties, and mycotoxin levels were evaluated. A statistical analysis revealed notable differences in the nutritional profiles of the maize varieties between the two regions, particularly in the protein and lutein content. The peak viscosity ranged from 6430 to 8599 cP and from 4548 to 8178 cP in the maize varieties from the Coruche and Golegã regions, respectively. Additionally, a significant correlation was observed between the climatic conditions and the grain nutritional quality components (p < 0.05). The M variety showed the highest ash content, protein content, final viscosity, and setback viscosity and the lowest peak viscosity. The Y variety revealed the lowest fat, fiber, and lutein content and the maximum peak viscosity. The incidence of mycotoxins was notably higher in the varieties from Coruche, which was potentially attributable to higher temperatures and lower precipitation levels leading to more frequent drought conditions. Fumonisin B1 was detected in 58% of the varieties from Coruche and 33% of the samples from Golegã, while deoxynivalenol was found in 87% and 80% of the varieties from Coruche and Golegã, respectively. The H variety, which was harvested in Coruche, exhibited the highest number of fumonisins and higher amounts of protein, lutein, and fat, while fumonisins were not detected in the Golegã region, which was potentially influenced by the precipitation levels. The K variety revealed higher protein and lutein contents, a lower amount of fat, excellent pasting properties (a higher peak viscosity and holding strength and a lower peak time), and no fumonisins B1 or B2. This variety may be considered well adapted to higher temperatures and drier conditions, as verified in the Coruche region. In conclusion, our study underscored the profound impact of environmental factors on the quality and occurrence of mycotoxins in maize varieties.

Effect of extraction pH on amino acids, nutritional, in-vitro protein digestibility, intermolecular interactions, and functional properties of guar germ proteins.

The chemical compositions, intermolecular interactions, and functional properties of guar germ proteins (GGP) were investigated at different extraction pH (7 to 11). The protein efficiency ratio, essential amino acid index (46.53), predicted biological value (39.02), nutritional index (42.67), and protein purity (91.69 %) were found to be highest at pH 9. The in-vitro protein digestibility of GGP sample was highest at pH 11. From SDS-PAGE, the band intensity (<10 kDa) became thinner with an increase in extraction pH from 7 to 9 and then thicker. Meanwhile, smallest particle size and weaker ionic and hydrogen bonds were found at pH 11. The ß-sheet content was more dominating in GGP samples. Moreover, higher denaturation temperatures of GGP samples indicated that protein molecules had a compact tertiary structure. Furthermore, the GGP extracted at pH 7 showed better functional properties. The principal component analysis suggested that pH 9 was more suitable for isolating GGP.

Zinc supports liver regeneration after partial resection.

Objectives: Safe removal of extensive liver tumor burdens depends on regeneration of the remnant liver, which requires a large amount of zinc over a short period of time. We studied how zinc influences regeneration. Material and Methods: We measured perioperative serum zinc concentrations after liver cancer diagnosis in 77 patients undergoing hepatectomy to determine how serum zinc affected short-term outcomes and remnant liver regeneration. Results: Serum zinc concentration at diagnosis showed no correlation with inflammatory or nutritional parameters except for a weak correlation with the lymphocyte-to-monocyte ratio. When patients were divided into a high pre-hepatectomy zinc group (≥75 µg/dL, n= 39, H group) and a low zinc group (<75 µg/dL, n= 38, L group), short-term results such as mortality (p> 0.999), morbidity (p= 0.490), and hospital stay (p= 0.591) did not differ between groups. However, hypertrophy in the future liver remnant after hepatectomy in the H group (127.7 ± 24.7% of original volume) was greater than in the L group (115.9 ± 16.7%, p= 0.024). In a subgroup of patients with extended hepatectomy, hypertrophy was 130.9 ± 26.8% in the H group vs. 116.4 ± 16.5% in the L group (p= 0.037). Conclusion: Greater serum zinc at diagnosis was associated with greater hypertrophy in the future liver remnant.

Relationship Between Start of Feeding and Functional Outcome in Aspiration Pneumonia: A Retrospective Cohort Study.

INTRODUCTION: Aspiration pneumonia is the predominant form of pneumonia in the elderly. Low oral intake levels and malnutrition have been reported to be associated with increased mortality and loss of function in aspiration pneumonia. However, the relationship between start of feeding and readmission, which is associated with malnutrition and low oral intake levels, has not been reported. The purpose of this study was to clarify the relationship between start of feeding and functional prognosis in aspiration pneumonia. METHODS: Patients' basic information, comorbidities, severity of pneumonia, swallowing function, time from admission to the start of feeding, geriatric nutritional risk index (GNRI), readmission, and Barthel index (BI) were evaluated in 160 patients. The patients were divided into two groups-a readmission group and a non-readmission group-and statistical verification was performed. RESULTS: The readmission group was 62 cases (38.8%). Univariate analysis showed that the time from admission to the start of feeding was significantly longer in the readmission group (p < 0.001). Age was significantly higher and nutrition parameters were lower in the readmission group (p = 0.001, 0.006). Furthermore, according to logistic regression analysis, readmission was associated with age (odds ratio, 1.063; p = 0.007; 95% confidence interval (CI) 1.017-1.111) and time from admission to the start of feeding (odds ratio 1.080; p < 0.001; 95% CI 1.025-1.137). CONCLUSION: The time from admission to the start of feeding was significantly longer in the readmitted patients. A comprehensive intervention with multidisciplinary collaboration should be performed from the early stage of hospitalization. TRIAL REGISTRATION: This study is registered in the UMIN-Clinical Trials Registry (UMIN-CTR). UMIN-CTR meets the criteria of the International Committee of Medical Journal Editors (ICMJE). (Registration number: 000047141).

According to logistic regression analysis, readmission was associated with age and time from admission to the start of feeding. The time from admission to the start of feeding was significantly longer in the readmitted patients. A comprehensive intervention with multidisciplinary collaboration should be performed from the early stage of hospitalization. It is necessary to carry out indirect swallowing training from the time of hospitalization, nursing care such as feeding assistance, oral care, and functional training; to periodically evaluate intention; to identify problems by conference; and to decide on a treatment plan.

Cerebral Ischemic Complications After Surgical Revascularization for Moyamoya Disease: Risk Factors and Development of a Predictive Model Based on Preoperative Nutritional Blood Parameters.

Objectives: Cerebral ischemic complications are common after revascularization in patients with moyamoya disease (MMD). Risk factors from specific laboratory variables have only been assessed by limited research. This study was to investigate the association between postoperative cerebral ischemia and nutritional blood parameters and examine predictive values of such risk factors in adults. Methods: Preoperative demographics and nutritional blood parameters of patients with MMD who received revascularization at our institution from 2012 to 2021 were retrospectively reviewed. Univariate analysis and multivariable logistic regression were used to identify independent risk factors for the onset of postoperative cerebral ischemic complications. Predictive values were tested and a model incorporating these independent risk factors was created using the R program. Area under the receiver operating characteristic curve (AUC) was used for testing its discriminability. Results: Postoperative cerebral ischemic complications occurred in 32 patients of 100 included procedures. Surgery on the left hemisphere, lower admission modified Rankin Scale (mRS) score, aberrant nutritional parameters including low white blood cell (WBC), and high total cholesterol (TC) were significantly associated with cerebral ischemic complications after revascularization. The intriguing role of WBC might be explained by altered immunomodulation. The AUC of this model with novel nutritional parameters yielded a value of 0.811, presenting better predictive accuracy. Additionally, the model was visualized in the form of a nomogram and translated into a user-friendly calculator to generate individual risk. Conclusions: Surgical side, admission mRS score, WBC, and TC were independent risk factors for postoperative cerebral ischemic complications. The model composed of these four parameters was promising to be adopted in clinical practice.

Evaluation of dietary Perilla frutescens seed on performance and carcass quality in finishing castrated male Songliao black pigs.

OBJECTIVES: This study was conducted to investigate the effects of dietary supplementation of Perilla frutescens seed (PFS) on growth performance, blood profiles, meat quality and meat nutrient characteristics in finishing castrated male Songliao black pigs. METHODS: A total of 80 castrated male Songliao black pigs with an average initial body weight (BW) of 84.1 ± 2.1 kg were used in a 75 days feeding trial. All pigs were randomly assigned into four dietary treatments: CON, basal diet; PFS3.0, basal diet + 3.0% of PFS; PFS6.0, basal diet + 6.0% of PFS and PFS9.0, basal diet + 9.0% of PFS. RESULTS: As a result of this experiment, dietary supplementation of PFS improved the growth performance parameters, blood albumin and blood lipid parameters. Whereas, on FBW, average daily feed intake and average daily gain there showed a non-dose-dependent manner that pigs in PFS9.0 had lowest performance compared with other two PFS treatments. Furthermore, meat colour of yellowness, pH, cook meat rate, moisture, crude protein and crude fat were increased by PFS addition. However, lower growth performance was observed in PFS9.0 group. As well as, dietary inclusion of PFS also alters the meat amino acid composition and meat fatty acids composition. Particularly, umami amino acid contents and polyunsaturated fatty acid were all enhanced by PFS addition. CONCLUSIONS: In summary, dietary supplementation of PFS have beneficial effects on the performance and meat quality and nutritional values in Songliao black pigs.

Sodium and/or fluid restriction and nutritional parameters of adult patients with heart failure: A systematic review and meta-analysis of randomized controlled trial.

INTRODUCTION: Heart failure (HF) is a clinical syndrome resulting from the structural and/or functional impairment of blood supply to tissues. Congestion and edema associated with water retention are the main symptoms presented by patients. Fluid (FR) and sodium restriction are non-pharmacological measures indicated in clinical practice to mitigate this symptom, despite their low evidence level. AIM: Assessing the impact of sodium and/or fluid restriction on nutritional parameters of adult patients with HF, based on systematic review with meta-analysis. METHODS: The study was conducted in June 2020, on the following databases: EMBASE, PubMed/MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL) and Web of Science. Citations were also collected in the gray literature such as thesis banks and preprints. Randomized clinical trials conducted with patients in the age group 18 years, or older, who were hospitalized or under outpatient/clinical follow-up, and who were subjected to intervention based on fluid and/or sodium restriction in comparison to the control, were herein selected. RESULTS: Although FR-based diets are effective in reducing liquid intake, they increase individuals' thirst sensation and body weight in comparison to non-FR diets. The association between this intervention and sodium restriction is also effective in reducing liquid intake as sodium intake decreases. However, the association of the most severe (<2000 mg/day) and moderate (2000-2400 mg/day) sodium restrictions with FR has reduced energy intake, although without evidence of weight change - only the most severe sodium restriction was capable of keeping individuals' thirst sensation. In addition, moderate sodium restrictions (2300 to 3000 mg/day) in association with FR were capable of decreasing urinary sodium excretion. On the other hand, prescriptions of severe or moderate sodium restriction (<2,400 mg/d) alone have reduced individuals' body weight and BMI, although they did not change their caloric intake. However, severe sodium restriction (<2,000 mg) has led to higher body weight than the low-sodium diet (2000 to 2,4000 mg/day). CONCLUSION: Sodium restriction may not be an effective strategy because it adversely affects individuals' weight, a fact that suggests increased congestion. Weight-based FR is supported to bethe best way to individualize this non-pharmacological treatment and it does not appear to affect nutritional parameters capable of putting patients with HF at higher malnutrition risk.

Preoperative Prognostic Nutritional Index is a significant predictive factor for posthepatectomy bile leakage.

BACKGROUNDS/AIMS: It is known that preoperative nutritional status can influence patient outcomes after hepatectomy. Prognostic Nutritional Index (PNI) is a useful parameter to reflect patient outcomes undergoing gastro-intestinal surgery. The aim of this study was to retrospectively evaluate relationships of nutritional parameters, demographics, and surgical records with postoperative outcomes in a cohort study. METHODS: Curative hepatectomy was performed for 182 patients at the University of Miyazaki between 2015 and 2018. Each preoperative level of albumin, prealbumin, lymphocyte, total cholesterol, or the comprehensively calculated Onodera's PNI was examined as a nutritional parameter. RESULTS: The mean PNI was 39.6 ± 5.1, with PNI below 40 observed in 91 (50.0%) patients. Nutritional parameters were not different among patients with various liver diseases. Serum albumin or prealbumin level was significantly correlated with each hepatic parameter (p < 0.01). Prealbumin and total cholesterol levels were significantly correlated with postoperative prothrombin activity (p < 0.05). Albumin or prealbumin levels and PNI were significantly lower in patients with posthepatectomy complications, particularly bile leakage in comparison those without such complications (p < 0.05). Multiple logistic analysis showed that albumin level was an independent risk factor for complications after hepatectomy (risk ratio [RR]: 1.33) and that lymphocyte count was an independent risk factor for bile leakage (RR: 1.28) (p < 0.05). The cut-off level of albumin was approximately 3.8 mg/dL and that of lymphocyte count was 1,320/mm3. CONCLUSIONS: Preoperative PNI reflected perioperative liver functional status. It was a predictive parameter for postoperative complications, particularly biliary leakage.

From bench to worktop: Rapid evaluation of nutritional parameters in liquid foodstuffs by IR spectroscopy.

We evaluated the use of attenuated total reflectance infrared spectroscopy for simultaneous in situ quantification of the nutritional composition of liquid food stuffs in the industrial kitchen context. Different methodologies were compared, including dry and wet acquisition along with instrument parameters and measurement times of 4 and 60 s. The most effective technique was 1-minute measurement, with prediction errors of 2.6, 0.7, 1.0, 2.2, 0.8, 2.4 g/100 mL and 150 Kcal, for carbohydrates, proteins, fat, sugars, saturated fat, water and energy values, respectively.The 4-second method resulted in larger errors but was more applicable for inline measurements. Dry measurements successfully predicted the fractions of proteins, fat, carbohydrates, and sugars, relative to total solids. An app was created to facilitate implementation in a kitchen environment. Compared with other techniques recommended by the FAO, the approach offered a simple alternative for simultaneous prediction of nutritional parameters in an industrial kitchen set-up.
