    Background. The inflammatory reactions are stronger after surgery of malnourished preoperative patients. Many studies have shown vitamin and trace element deficiencies appear to affect the functioning of immune cells. Enteral nutrition is often inadequate for malnourished patients. Therefore, total parenteral nutrition (TPN) is considered an effective method for providing preoperative nutritional support. TPN needs a central vein catheter, and there are more risks associated with TPN. However, peripheral parenteral nutrition (PPN) often does not provide enough energy or nutrients. Purpose. This study investigated the inflammatory response and prognosis for patients receiving a modified form of PPN with added fat emulsion infusion, multiple vitamins (MTV), and trace elements (TE) to assess the feasibility of preoperative nutritional support. Methods. A cross-sectional design was used to compare the influence of PPN with or without adding MTV and TE on malnourished abdominal surgery patients. Results. Both preoperative groups received equal calories and protein, but due to the lack of micronutrients, patients in preoperative Group B exhibited higher inflammation, lower serum albumin levels, and higher anastomotic leak rates and also required prolonged hospital stays. Conclusion. Malnourished patients who receive micronutrient supplementation preoperatively have lower postoperative inflammatory responses and better prognoses. PPN with added fat emulsion, MTV, and TE provides valid and effective preoperative nutritional support. PMID:26000296

    Full Text Available Gastric cancer is a catabolic disease, where the tumor acts consuming the nutritional reserves of the patient, leading to nutritional loss and poor clinical prognosis.The purpose of this study was to evaluate thepre-surgical nutritional intervention through oral nutritional therapy in patients with gastric cancer admitted to a public hospital in the city of Santos, Sao Paulo, Brazil. Subjective global assessment was applied tospecific cancer patients. Supplementation immunomodulatory lasted on average 11 days during the surgery and predecessor dosage used was 2 days units.Sample of 15 elderly patients, and 40% in baseline nutritional status depleted. After the intervention, only 20% lost weight. There was improvement in the average serum albumin (2.6 g / dl at baseline and 2.9 g /dl after supplementation and more than half the sample (60% showed no postoperative complications.Nutrition immunomodulatory proved beneficial, contributing to maintenance and / or improvement in nutritional status, an important factor in reducing postoperative complications.

    Preoperative nutritional status and physical function are important predictors of mortality and morbidity after cardiac surgery. However, the influence of nutritional status before cardiac surgery on physical function and the progress of postoperative rehabilitation requires clarification. To determine the effect of preoperative nutritional status on preoperative physical function and progress of rehabilitation after elective cardiac surgery. We enrolled 131 elderly patients with mean age of 73.7 ± 5.8 years undergoing cardiac surgery. We divided them into two groups by nutritional status as measured by the Geriatric Nutritional Risk Index (GNRI): high GNRI group (GNRI ≥ 92, n = 106) and low GNRI group (GNRI nutritional status as assessed by the GNRI could reflect perioperative physical function. Preoperative poor nutritional status may be an independent predictor of the retardation of postoperative rehabilitation in patients undergoing elective cardiac surgery.

    The objective of this study was to define how preoperative nutritional face-to-face counseling on child's fasting affects parental knowledge, preoperative need-for-information, and anxiety, in pediatric ambulatory tonsillectomy. The participants in the prospective, randomly allocated study were parents (intervention 62/control 62) with children (4-10 years) admitted for ambulatory tonsillectomy. Data were collected by the knowledge test designed for the study and with The Amsterdam preoperative anxiety and information scale (APAIS). The intervention group was invited to a preoperative visit to receive written and verbal face-to-face counseling. They were initiated into the child's active preoperative nutrition. The parents of the control group received current information without face-to-face counseling. The parents followed the instructions. Their knowledge about the child's fast increased (p=0.003), and need-for-information and anxiety decreased (ppreoperative face-to-face counseling with written information improves parental knowledge about the child's fasting and active preoperative nutrition, and relieves their need-for-information and anxiety. The primary responsibility remains with the health care professionals when the active preoperative nutrition of the child and counseling on it are introduced into nursing practice.

    AIM: To evaluate the effects of preoperative immunonutrition and other nutrition models on the cellular immunity parameters of patients with gastrointestinal tumors before surgical intervention. In addition, effects on postoperative complications were examined.METHODS: Patients with gastrointestinal tumors were randomized into 3 groups. The immunonutrition group received a combination of arginine, fatty acids and nucleotides. The second and third group received normal nutrition and standard enteral nutrition,respectively. Nutrition protocols were administered for 7 d prior to the operation. Nutritional parameters,in particular prealbumin levels and lymphocyte subpopulations (CD4+, CD8+, CD16+/56+, and CD69 cells) were evaluated before and after the nutrition protocols. Groups were compared in terms of postoperative complications and duration of hospital stay.RESULTS: Of the 42 patients who completed the study, 16 received immunonutrition, 13 received normal nutrition and 13 received standard enteral nutrition.prealbumin values were low in every group, but this parameter was improved after the nutritional protocol only in the immunonutrition group (13.64 ± 8.83vs 15.98 ± 8.66, P = 0.037). Groups were similar in terms of CD4+, CD16+/56, and CD69+ prior to the nutritional protocol; whereas CD8+ was higher in the standard nutrition group compared to the immunonutrition group. After nutritional protocols,none of the groups had an increase in their lymphocyte subpopulations. Also, groups did not differ in terms of postoperative complications and postoperative durations of hospital stay.CONCLUSION: Preoperative immunonutrition provided a significant increase in prealbumin levels,while it did not significantly alter T lymphocyte subpopulation counts, the rate of postoperative complications and the duration of hospital stay.

    Effects of preoperative one week enteral nutrition (EN) support on the postoperative nutritional status, immune function and inflammatory response of gastric cancer patients were investigated. 106 cases of gastric cancer patients were randomly divided into preoperative one week EN group (trial group) and early postoperative EN group (control group), which were continuously treated with EN support until the postoperative 9th day according to different treatment protocols. All the patients were checked for their body weight, skinfold thickness, upper arm circumference, white blood cell count (WBC), albumin (ALB), prealbumin (PA), C-reactive protein (CRP), humoral immunity (IgA, IgG), T cell subsets (CD4, CD8 and CD4/CD8), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), etc. on the preoperative and the postoperative 1st and 10th day, respectively. PA and IgG levels of the experimental group were higher than those of the control group on the postoperative 10th day, whereas IL-6 level of the experimental group was lower than that of the control group. EN support for preoperative gastric cancer patients will improve the postoperative nutritional status and immune function, alleviate inflammatory response, and facilitate the recovery of patients.

    Full Text Available Context Weight loss and malnutrition are disorders observed in colorectal cancer patients. Objectives We sought to evaluate the immediate preoperative nutritional status of patients with colorectal cancer. Methods This is a cross-sectional clinical study conducted at a single center. Sixty-six consecutive patients in preoperative for elective surgical treatment were studied. The clinical history, socio-demographic data and nutritional status of the patients were evaluated using Subjective Global Assessment and objective (anthropometry methods. The primary outcome measures were nutritional status classification as nourished or malnourished and the relationship between nutritional status and socio-demographic and clinical features. Results Most of patients exhibited left colon tumors and disease stage II. According to the Subjective Global Assessment, 36.4% of patients were malnourished. Malnutrition ranged from 7.6% to 53% depending on the evaluation method used, with poor correlation to Subjective Global Assessment. The prevalence of malnutrition was significantly greater in females and non-married patients and in those with two or more symptoms of colorectal cancer. Conclusions More than a third of patients in the immediate preoperative period for colorectal cancer exhibited malnutrition. Therefore, routine nutritional assessment is highly advisable so that appropriate measures may be taken to minimize the potential postoperative complications.

    Objective Impaired immunonutritional status has disadvantageous effects on outcomes for cancer patients. Preoperative albumin-to-globulin ratio (AGR) and the prognostic nutrition index (PNI) have been used as prognostic factors in various cancers. We aimed to evaluate the clinical significance of the AGR and PNI in glioblastoma. Materials and methods This retrospective analysis involved 166 patients. Demographic, clinical, and laboratory data were collected. AGR and the PNI were calculated as AGR = albumin/(total serum protein − albumin) and PNI = albumin (g/L) + 5 × total lymphocyte count (109/L). Overall survival (OS) was estimated by Kaplan–Meier analysis. Receiver-operating characteristic analysis was used to assess the predictive ability of AGR and the PNI. Cox proportional-hazard models estimating hazard ratios (HRs) and 95% confidence intervals (CIs) were used for univariable and multivariable survival analyses. Results The cutoff values of AGR and PNI were 1.75 and 48. OS was enhanced, with high AGR (>1.75) and the PNI (>48) (Pglioblastoma. AGR and the PNI could also help in developing good adjuvant-therapy schedules. PMID:28223828

    AIM To investigate the interference of methionine-free parenteral nutrition plus 5-Fu (-MetTPN + 5-Fu) in gastric cancer cell kinetics and the side effects of the regimen. METHODS Fifteen patients with advanced gastric cancer were randomly divided into two groups, 7 patients were given preoperatively a seven-day course of standard parenteral nutrition in combination with a five-day course of chemotherapy (sTPN + 5-Fu), while the other 8 patients were given methionine-deprived parenteral nutrition and 5-Fu (-MetTPN + 5-Fu).Cell cycles of gastric cancer and normal mucosa were studied by flow cytometry (FCM). Blood samples were taken to measure the serum protein, methionine (Met) and cysteine (Cys)levels, and liver and kidney functions. RESULTS As compared with the results obtained before the treatment, the percentage of Gn/G1 tumor cells increased and that of S phase decreased in the -MetTPN + 5-Fu group, while the contrary was observed in the sTPN + 5-Fu group.Except that the ALT, AST and AKP levels were slightly increased in a few cases receiving -MetTPN + 5-Fu, all the other biochemical parameters were within normal limits. Serum Cys level decreased slightly after the treatment in both groups. Serum Met level of patients receiving sTPN + 5-Fu was somewhat higher after treatment than that before treatment; however,no significant change occurred in the -MetTPN +5-Fu group, nor operative complications in both groups. CONCLUSION -MetTPN + 5-Fu exerted a suppressive effect on cancer cell proliferation,probably through a double mechanism of creating a state of "Met starvation" adverse to the tumor cell cycle, and by allowing 5-Fu to kill specifically cells in S phase. Preoperative shortterm administration of-MetTPN + 5-Fu had little undesirable effect on host metabolism.

    The aim of this study is to confirm the predictive value of controlling nutritional status (CONUT), as a postoperative prognostic marker for esophageal cancer patients undergoing esophagectomy. We retrospectively analyzed 373 patients who underwent three-incision esophagectomy with 2- or 3-field lymphadenectomy for esophageal cancer between April 2005 and March 2016. The patients were divided into three groups based on the degree of preoperative malnutrition as assessed by CONUT: normal, light malnutrition, and moderate or severe malnutrition. The patients with moderate or severe malnutrition experienced a significantly higher frequency of reoperation (normal or light malnutrition, 6.3%; moderate or severe malnutrition, 18.2%; P = 0.033) and a higher tendency for respiratory morbidities (normal or light malnutrition, 14.0%; moderate or severe malnutrition, 27.3%; P = 0.088). Cox regression analysis identified a significantly poor prognosis, in both overall survival (hazard ratio (HR), 3.56; 95% confidence interval (CI), 1.714-7.390; P cancer-specific survival (HR, 3.41; 95% CI, 1.790-6.516; P = 0.046). CONUT is convenient and useful for preoperatively assessing malnutrition and prognosis of esophageal cancer patients who underwent surgery.

    This study examined the relationship between pre-operative nutritional status and systemic inflammatory response syndrome (SIRS) or sepsis following major vascular surgery. Subjects undergoing open AAA repair, EVAR or lower limb revascularisation were studied prospectively. Pre-operative nutrition was assessed clinically using Mini-Nutritional Assessment (MNA) and body composition was measured by dual energy X-ray absorptiometry (DEXA) scanning. SIRS severity was assessed for 5 post-operative days and sepsis noted within 30 days of surgery. Using MNA, neither SIRS severity nor sepsis occurrence differed significantly between 'well-nourished' subjects and those 'at risk of malnutrition'. Using DEXA, negative associations existed between body mass index and both SIRS score and SIRS duration. Fat free mass (FFM) was negatively associated with SIRS score and duration. Negative associations also existed between skeletal muscle mass (SMM) and SIRS score and duration. SMM was also negatively correlated with post-operative length of stay in hospital. There were no significant correlations between sepsis and any nutritional indices. Lower pre-operative nutritional indices, indicating protein energy malnutrition, were associated with more severe systemic inflammatory responses following major vascular surgery.

    Nowadays, there is an increasing quest for beauty and the models proposed by fashion goods and service segments, to achieve the perfect body. The standard of beauty corresponds to a thin body, without considering health aspects. The number of women who go on diets to control weight is increasing; and taking this into consideration the objective of this study is to conduct a bibliographical review and extract data on esthetics and body image to support the practice of nutritional care. Socio-cultural aspects, which motivate the quest for the perfect body, as well as body, beauty, esthetics, nutritional counseling and cognitive behavior therapy were examined in this survey. On the basis of this work, it is possible to conclude that the continuing obsession with the body may lead the person to go on diets and other drastic methods to control weight, such as surgical procedures. In this respect, nutritional care is far more than merely recommending a standard diet or giving information, as it represents providing an effective model for nutritional reeducation, prioritizing improvement in the style and quality of life. This article provides data about enhancing esthetics and beauty by means of appropriate nutrition.

    Preoperative nutritional status not only correlates with the incidence of postoperative complications but also may be indicative of long-term outcomes for patients with cancer. The impact of preoperative nutritional status on outcomes for patients undergoing gastrectomy for gastric cancer (GC) was investigated. The study reviewed 594 patients treated for GC by gastrectomy at the authors' hospital between January, 2004 and December, 2010. Onodera's prognostic nutritional index (PNI) was invoked, using an optimal cut point to group patients as having high (PNI > 45; n = 449) or low (PNI ≤ 45; n = 145) nutritional status. Clinicopathologic features, perioperative results, and long-term outcomes, including cause of death, were compared. Multivariate analysis of 5-year overall survival (OS) and disease-specific survival (DSS) indicated that low PNI was independently associated with unfavorable outcomes for patients with GC. In subgroup analysis, the 5-year OS and DSS rates for patients with GC at stages 1 and 2 were significantly worse in the low PNI group than in the high PNI group. Although wound and extrasurgical field infections also tended to be more frequent in the low PNI group, postoperative intraabdominal infections did not differ significantly by group. Preoperative PNI may have merit as a gauge of prognosis for patients with GC at stages 1 and 2, but PNI and postoperative morbidity showed no correlation in this setting.

  1. Correlation between the preoperative state of nutrition and the frequency of postoperative problems after video-assisted gastrostomy in children.

    Full Text Available Gastrostomy operations are performed on children referred to the pediatric surgical clinic without being influenced by the patient’s state of nutrition. This has been motivated by the idea that a gastrostomy would enable a fast and secure improvement in this regard. The question arises whether an improvement in the preoperative nutritional status would reduce the number of postoperative complications. The aim of the study was to test the hypothesis that the frequency of postoperative complications after a video-assisted gastrostomy is correlated to the child’s preoperative state of nutrition. Fifty consecutive children with severe nutritional problems underwent a video-assisted gastrostomy operation where gastrostomy buttons were placed as the initial surgical feeding tube. At the time of the operation, the children’s nutritional parameters were registered routinely. After the operation, the children were followed up prospectively for six months and all complications were documented according to a protocol. The children were ranked according to the severity and frequency of postoperative complications and problems. Correlation to nutritional parameters was calculated. The children did not present with any serious postoperative intra-abdominal complications. There was a significant correlation between the frequency of minor complications and the child’s state of nutrition, measured as the number of standard deviations from normal length and weight as well as phosphate, magnesium, and iron levels in the blood. This study revealed a significant correlation between the patients’ state of nutrition and the postoperative complications during the first postoperative six months. Thus, the findings support a routine of nutritional evaluation prior to performing a gastrostomy operation.

    Background Triple-phase enhancement of multi-slice computed tomography (MSCT) has markedly improved the diagnostic accuracy of hepatocellular carcinoma (HCC), and MSCT angiography (MSCTA) has been proved useful in detecting vascular anatomy noninvasively. This study aimed to explore the value of MSCTA by triple-phase enhancement in preoperative evaluation of HCC.Methods Fifty-six consecutive cases of primary HCC scheduled for resection were studied with MSCTA by triple-phase enhancement. The raw data images were processed on a workstation for multiplanar reconstruction (MPR) and three-dimensional (3D) reconstruction. The findings after processing of the data were compared with those after surgery or intraoperative sonography. Results The false positive rate of MSCTA by triple-phase enhancement was 10.1% and its false negative rate was 4.3% in detecting HCC. No significant difference was observed in MSCTA and surgery or intraoperative sonography in detecting vascular anatomy anomalies and pathologic variations, whereas significant difference was found in detecting bile duct invasion with MSCT compared to intraoperative sonography.Conclusions MSCTA by triple-phase enhancement not only improves the detection of HCC, but also provides valuable preoperative information about hepatic vascular architecture and parenchyma. MSCTA by triple-phase enhancement is worthy of application as a non-invasive method in preoperative evaluation of HCC.

    To evaluate the diagnostic performance of contrast material-enhanced magnetic resonance (MR) angiography for preoperative detection and localization of accessory pudendal arteries (APAs) in patients with prostate cancer. This prospective study was approved by the institutional review board, and informed consent was obtained. Between July 2007 and December 2010, 127 patients underwent contrast-enhanced MR angiography following prostate MR imaging at 3.0 T before robot-assisted laparoscopic radical prostatectomy (RALP). APAs were defined as any arteries located in the periprostatic region and anastomosed with the common penile artery or its branches; they were then subclassified into lateral and apical APAs. For detecting and localizing APAs, MR angiograms were evaluated prospectively by one reader and retrospectively by two independent blinded readers. Diagnostic performance was determined on a per-patient basis by using surgical findings as the reference standard. In addition, the origin of APAs identified at both surgery and contrast-enhanced MR angiography was determined by consensus of two retrospective readers. Interreader agreements were assessed by using k statistics. At surgery, 19 APAs (seven right apical, three left apical, four right lateral, and five left lateral) were detected in 16 patients, and 16 of these APAs were localized in 13 patients at preoperative contrast-enhanced MR angiography. Prospectively, sensitivity, specificity, and accuracy of contrast-enhanced MR angiography for the localization of APAs were 81.3%, 93.7%, and 92.1%, while retrospectively they were 87.5%, 91.9%, and 91.3% for reader 2 and 75.0%, 90.1%, and 88.2% for reader 3, respectively. Overall interreader agreement was substantial (k = 0.795). Nine and seven APAs originated from the obturator artery and the inferior vesical artery, respectively. Contrast-enhanced MR angiography can be used for the preoperative detection of APAs in patients with prostate cancer. © RSNA, 2012.

    A nutritional indicator suitable for predicting complications after esophagectomy has not been confirmed. The nutritional screening tool CONUT is a potential candidate. We retrospectively analyzed 352 patients who underwent elective esophagectomy with lymphadenectomy for esophageal cancer between April 2005 and December 2014. Patients were divided into three groups according to the malnutrition degree in controlling nutritional status (CONUT): normal, light malnutrition, moderate or severe malnutrition. The numbers of patients assigned to the normal, light malnutrition, and moderate or severe malnutrition groups were 205, 126, and 21, respectively. One hundred forty-seven (41.8 %) patients were considered malnourished. Patients with moderate or severe malnutrition had a significantly high incidence of any morbidity, severe morbidities, and surgical site infection. Hospital stay in patients with moderate or severe malnutrition was significantly longer. Logistic regression analysis suggested that moderate or severe malnutrition was an independent risk factor for any morbidity [hazard ratio (HR) 2.75, 95 % confidence interval (CI) 1.081-7.020; p = 0.034] and severe morbidities (HR 3.07, 95 % CI 1.002-9.432; p = 0.049). CONUT was a convenient and useful tool to assess nutritional status before esophagectomy. Patients with moderate or severe malnutrition according to CONUT are at high risk for postoperative complications.

  9. NUTRITIONAL ENHANCEMENT OF ALFALFA THROUGH GENETIC ENGINEERING

    Directory of Open Access Journals (Sweden)

    2008-09-01

    Full Text Available Alfalfa (Medicago sativa L. is a pasture legume crop of primary importance to animal production throughout the world. The nutritional quality of alfalfa, as of other leguminous forage crops, is mainly determined by their content in selected essential amino acids (EAAs, such as methionine (Met and cysteine (Cys. In alfalfa, however, these S-containing amino acids constitute only about 1% or less of crude proteins (Frame et al., 1998. This is significantly less than the 3.5% Met+Cys content in the recommended FAO reference protein (FAO, 1973. Recent advances in genetic engineering allow to use the transgenic approach to increase the content of specific essential amino acids in target plant species. A number of different molecular approaches have been developed to address this issue, such as over-expression of a heterologous or homologous Met-rich protein, expression of a synthetic protein, modification of protein sequence, and metabolic engineering of the free amino acid pool and protein sink. To study the possibility of transgenic enhancement of nutritional quality of alfalfa, we used the approach of expression of a heterologous protein rich in Met+Cys in cells of alfalfa. The T-DNA introduced into the genome of alfalfa, using Agrobacterium tumefaciens-mediated genetic transformation, contained the selectable merker gene nptII for kanamycin (Kn resistance, and a cDNA of Ov gene from Japanese quail (Coturnix coturnix coding for a high Met+Cys containing ovalbumine (Mucha et al., 1991, both under constitutive promoters. After cocultivation of petiole segment- and leaf blade-explants of two highly embryogenic alfalfa genotypes Rg9/I-14-22 and Rg11/I-10-68 (Faragó et al., 1997 with cells of A. tumefaciens strain AGL1 carrying the nptII and Ov genes, and selection of transgenic cells on Kn containing selective media, more than one hundred putatively transgenic regenerants were obtained through somatic embryogenesis.

    To assess whether gadoxetic acid-enhanced MRI could be used as a prognostic factor for intrahepatic mass-forming cholangiocarcinomas (IMCCs). Forty-one patients with pathologically proven IMCCs who underwent preoperative gadoxetic acid-enhanced MRI were included. The signal intensity of the IMCCs on hepatobiliary phase (HBP) MRI was qualitatively analyzed by two radiologists, and categorized into intermediate or hypointense groups. Analysis of clinicopathological prognostic factors and correlations of imaging and histology were also performed. Survival time and time to recurrence (TTR) were analyzed. Of the 41 IMCCs, 23 were in the intermediate group and 18 were in the hypointense group on HBP MRI. IMCCs in the intermediate group were associated with shorter survival time (P = 0.048) and TTR (P = 0.002) than the IMCCs of the hypointense group. Only the intermediate group on HBP MRI had a significantly shorter TTR on multivariate analysis (P = 0.012). The IMCCs of the intermediate group showed a tendency for more abundant tumour fibrous stroma than those of the hypointense group (P = 0.027). The enhancement of IMCCs on HBP gadoxetic acid-enhanced MRI appears to correlate with tumour aggressiveness and outcomes due to the tumour fibrous stromal component. Thus, HBP images could be a useful prognostic factor for IMCCs after surgery. (orig.)

    To establish the optimal cut-off value of the preoperative prognostic nutritional index (PNI) for prognosis according to the Tumor Node Metastasis (TNM) stage of hepatocellular carcinoma (HCC) after curative resection. This retrospective study reviewed the records of 375 patients. The optimal cut-off value of the PNI was established according to the TNM stage, and overall survival was compared between the low and high PNI groups. The optimal cut-off value of the PNI decreased with increasing TNM stage, with 52, 47, and 43 patients having stage I, II, and III HCC, respectively. A low preoperative PNI predicted a poorer overall survival than did a high PNI for stage I (P TNM stages and that the preoperative PNI is a favorable prognostic factor for stage I HCC.

    The prognostic Controlling Nutritional Status (CONUT) score is used to evaluate immuno-nutritional conditions and is a predictive factor of postoperative survival in patients with digestive tract cancer. We retrospectively analyzed clinicopathological features of patients with pathological stage I non-small cell lung cancer (NSCLC) to identify predictors or prognostic factors of postoperative survival and to investigate the role of preoperative CONUT score in predicting survival. We selected 138 consecutive patients with pathological stage I NSCLC treated from August 2005 to August 2010. We measured their preoperative CONUT score in uni- and multivariate Cox regression analyses of postoperative survival. A high CONUT score was positively associated with preoperative serum carcinoembryonic antigen level (p=0.0100) and postoperative recurrence (p=0.0767). In multivariate analysis, the preoperative CONUT score [relative risk (RR)=6.058; 95% confidence interval (CI)=1.068-113.941; p=0.0407), increasing age (RR=7.858; 95% CI=2.034-36.185; p=0.0029), and pleural invasion (RR=36.615; 95% CI=5.900-362.620; pcancer-specific survival (CS), and overall survival (OS), the group with high CONUT score had a significantly shorter RFS, CS, and OS than did the low-CONUT score group by log-rank test (p=0.0458, p=0.0104 and p=0.0096, respectively). The preoperative CONUT score is both a predictive and prognostic factor in patients with pathological stage I NSCLC. This immuno-nutritional score can indicate patients at high risk of postoperative recurrence and death. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    Administration of immuno-enhanced nutritional support may decrease postoperative morbidity, mortality, and infectious complications in cancer patients. The aim of this study was to verify that perioperative enteral diet, enriched with the nutrients arginine, ribonucleic acid (RNA), and ω-3 fatty acids improves outcomes of head and neck cancer patients undergoing major surgery. Forty patients with squamous cell carcinoma of the head and neck were studied. Group 1 received no preoperative nutritional support, whereas Group 2 received an oral formula with nutrients arginine, RNA, and ω-3 fatty acids. After surgery, Group 1 received a standard enteral formula, whereas Group 2 received an enriched enteral formula. Albumin (g/dl), prealbumin, fibrinogen, CRP, Il-6, and TNFa were measured 5 days before and 8 days after surgery. No statistically significant difference was observed for all the evaluated markers between postoperative and preoperative levels for both groups. The rate of complications was significantly reduced in the total number of patients receiving immunonutrition and in the particular subgroup of well-nourished patients receiving an immuno-enhanced diet. Perioperative enteral immuno-enhanced feeding in head and neck cancer patients undergoing major surgery may influence the postoperative outcomes by reducing the frequency rate of infections and wound complications.

    Parasagittal meningiomas (PSM) may pose a difficult surgical challenge since venous patency and collateral anastomoses have to be clearly defined for correct surgical planning. The aim of this study was to assess the diagnostic value of contrast-enhanced (CE) magnetic resonance venography (MRV) in the preoperative evaluation of venous infiltration and collateral venous anastomoses in patients with PSM. CE-MRV was compared with phase-contrast (PC) magnetic resonance (MR) angiography, conventional angiography (when available), and surgery as a reference. Twenty-three patients undergoing surgery for meningiomas located adjacent to the superior sagittal sinus were prospectively evaluated. All the patients underwent both conventional MR examination and MRV. This was performed by means of PC and CE techniques. Both sets of angiograms (CE and PC) were evaluated by two expert neuroradiologists to assess (1) patency of the sinus (patent/occluded), (2) the extent of occlusion (in centimeters), and (3) the number of collateral anastomoses close to the insertion of the meningioma. Eight patients underwent digital subtraction angiography (DSA). All patients were operated on, and intraoperative findings were taken as the gold standard to evaluate the diagnostic value of MRA techniques. PC-MRV showed a flow void inside the sinus compatible with its occlusion in 15 cases, whereas CE-MRV showed the sinus to be occluded in five cases. CE-MRV data were confirmed by surgery, showing five patients to have an occlusion of the superior sagittal sinus. The PC-MRV sensitivity was thus 100% with a specificity of 50%. In those cases in which both MRV techniques documented occlusion of the sinus, the extent of occlusion was overestimated by PC compared with CE and surgery. CE-MRV depicted 87% of collateral venous anastomoses close to the meningioma as subsequently confirmed by surgery, while PC showed 58%. In the preoperative planning for patients with meningiomas located close to a venous

    Background: The level of background parenchymal enhancement around tumor is known to be associated with breast cancer risk. However, there is no study investigating predictive power of parenchymal signal enhancement ratio (SER) around tumor for ipsilateral breast tumor recurrence (IBTR). Purpose: To investigate whether the breast parenchymal SER around the tumor on preoperative dynamic contrast-enhanced magnetic resonance imaging (MRI) is associated with subsequent IBTR in breast cancer patients who had undergone breast-conserving treatment. Material and Methods: Nineteen consecutive women (mean age, 44 years; range, 34-63 years) with breast cancer who developed IBTR following breast-conserving treatment and 114 control women matched for age, as well as T and N stages were included. We compared the clinicopathologic features of the two groups including nuclear grade, histologic grade, hormonal receptor status, human epidermal growth factor receptor-2 (HER-2) status, lymphovascular invasion, negative margin width, use of adjuvant therapy, and parenchymal SER around the tumor on preoperative DCE-MRI. The SER was measured on a slice showing the largest dimension of the tumor. Multivariate conditional logistic regression analysis was used to identify independent factors associated with IBTR. Results: In univariate analysis, ER negativity (odds ratio [OR] = 4.7; P = 0.040), PR negativity (OR = 4.0; P = 0.013), HER-2 positivity (OR = 3.6; P = 0.026), and a parenchymal SER greater than 0.53 (OR = 23.3; P = 0.011) were associated with IBTR. In multivariate analysis, ER negativity (OR = 3.8; P = 0.015) and a parenchymal SER greater than 0.53 (OR = 13.2; P = 0.040) on preoperative MRI were independent factors associated with IBTR. Conclusion: In addition to ER negativity, a higher parenchymal SER on preoperative MRI was an independent factor associated with subsequent IBTR in patients with breast cancer who had undergone breast-conserving treatment.

    This study was designed to compare the diagnostic performance of gadoxetic acid-enhanced magnetic resonance imaging (MRI) with gadobenate dimeglumine-enhanced MRI for preoperatively detecting hepatocellular carcinoma (HCC). Eighteen consecutive patients (17 men and one woman, age range: 31-73 years) with 22 HCCs underwent examinations with gadoxetic acid enhanced MRI and gadobenate dimeglumine-enhanced MRI on a 3.0-Tesla unit. The diagnosis of HCC was established after surgical resection and pathological conformation. Three observers independently reviewed each MR image in a random order on a tumor-by-tumor basis. The diagnostic accuracy of these techniques for the detection of HCC was assessed by performing an alternative free-response receiver operating characteristic (ROC) analysis. The sensitivity and positive predictive values were evaluated. The average value of the area under the ROC curve (Az) for gadoxetic acid enhanced MRI (0.887) was not significantly different from the Az (0.899) for gadobenate dimeglumine-enhanced MRI (p > 0.05). The overall sensitivities of gadoxetic acid enhanced MRI and gadobenate dimeglumine-enhanced MRI were 80% and 83%, respectively, with no significant difference (p > 0.05). The differences of the positive predictive values for the two contrast agents for each observer were not statistically significant (p > 0.05). The diagnostic performance of gadoxetic acid-enhanced MRI and gadobenate dimeglumine-enhanced MRI for preoperatively detecting HCC is quite similar

  20. Optimizing nutrition therapy to enhance mobility in critically ill patients.

    Critically ill patients are at high risk of malnutrition and lean body mass loss. Screening for malnutrition and performing detailed assessment of energy needs should be routine for patients admitted to intensive care units. Providing adequate calorie and protein provisions can attenuate muscle loss in many at-risk patients. Enteral nutrition is associated with decreased risks of morbidity and infections and is therefore preferred to parenteral nutrition in hemodynamically stable patients with favorable anatomy. Judicious use of steroids and paralytics in combination with adequate glucose control may decrease the risk of developing critical illness polyneuromyopathy. There is growing evidence for the potential immune-enhancing benefits of many micronutrients and vitamins in the critically ill, but more research is needed to determine which nutrients are most effective in which disease processes and what dosing regimens are safe and effective. Elderly, obese, and very young patients pose unique challenges for nutrition therapy and early mobility programs. Pairing early mobility programs with optimal nutrition therapy can help reduce morbidity, limit muscle loss, and speed recovery in intensive care unit patients.

An athlete's dietary requirements depend on several aspects, including the sport, the athlete's goals, the environment, and practical issues. The importance of individualized dietary advice has been increasingly recognized, including day-to-day dietary advice and specific advice before, during, and after training and/or competition. Athletes use a range of dietary strategies to improve performance, with maximizing glycogen stores a key strategy for many. Carbohydrate intake during exercise maintains high levels of carbohydrate oxidation, prevents hypoglycemia, and has a positive effect on the central nervous system. Recent research has focused on athletes training with low carbohydrate availability to enhance metabolic adaptations, but whether this leads to an improvement in performance is unclear. The benefits of protein intake throughout the day following exercise are now well recognized. Athletes should aim to maintain adequate levels of hydration, and they should minimize fluid losses during exercise to no more than 2% of their body weight. Supplement use is widespread in athletes, with recent interest in the beneficial effects of nitrate, beta-alanine, and vitamin D on performance. However, an unregulated supplement industry and inadvertent contamination of supplements with banned substances increases the risk of a positive doping result. Although the availability of nutrition information for athletes varies, athletes will benefit from the advice of a registered dietician or nutritionist

    An increased consumption of healthy foods to reduce chronic diseases risks is needed. We developed and evaluated a multigrain snack as a nutritive alternative to the highly consumed corn tortilla chips. Corn, wheat, and chickpea grains were boiled in 1% calcium oxide solution, steeped, washed, and ground before being mixed with soy protein isolate and oat flour to prepare the multigrain masa. Multigrain tortillas were moulded, baked, dried, and fried. Proximate composition, dietary fiber, protein quality, sensorial, and textural properties were evaluated. A commercial tortilla chip was used as control. The multigrain snack contained 153% more protein, 53% more dietary fiber, and 43 % less fat than commercial tortilla chips. Its lysine and isoleucine contents helped to increase the corrected-net protein utilization by 10%, while digestibility increased from 83.5 to 91.8% as compared to commercial tortilla chips. The mean breaking force was 6,082 g for the multigrain snack and 4,780 g for the commercial tortilla chips. The mean acceptability score for the multigrain snack was 12.1 (unstructured line scale 0-15 cm), and 82% of the panelists rated the snack as acceptable. In conclusion, a nutritionally enhanced multigrain tortilla snack was developed which provides significantly more dietary fiber and protein and less fat than traditional commercial corn tortilla chips, but with comparable appearance and high acceptability.

    The objectives of this study were 1) to examine the interactive influence of a compensatory nutrition regimen and lasalocid supplementation on dairy heifer growth performance and 2) to document the extent to which compensatory growth sustains lactation potential over the first two lactation cycles. Twelve Holstein heifers, weighing an average of 160 kg (about 6 mo of age) were randomly assigned to treatments arranged in a 2 x 2 factorial design. Treatment variables were two dietary regimens (control and stair-step compensatory nutrition) and two levels of lasalocid (0 and 200 mg/d). The control heifers were fed a diet containing 12% crude protein (CP) and 2.35 Mcal of metabolizable energy (ME) per kilogram of dry matter. The stair-step compensatory nutrition heifers were subjected to a phased nutrition regimen and reared according to an alternating 3-2-4-3-4-2-mo schedule. The first stair-step (prepubertal phase) consisted of energy restriction [17% CP and 2.35 Mcal/kg of ME] for 3 mo followed by realimentation (12% CP and 3.05 Mcal/kg of ME) for 2 mo. The second step (puberty and breeding) consisted of energy restriction for 4 mo followed by realimentation for 3 mo. The third step (gestation period) was energy restriction for 4 mo concluding with realimentation for 2 mo. Dry matter intake of heifers during the restriction phase was limited to 70% of the control intake. Heifers were given ad libitum access to a high energy density diet during realimentation to allow compensatory development. Stair-step heifers supplemented with lasalocid had the highest efficiency of growth (body weight gain/dry matter intake), suggesting synergistic metabolism of lasalocid with compensatory growth action. Compensatory growth induced during the last trimester enhanced metabolic status by increasing circulating insulin and decreasing triglyceride levels. Heifers on the stair-step regimen had a significant increase in milk yield during the first (21%) and second (15%) lactation

    Purpose: to evaluate preoperative contrast enhanced MR imaging in clinically, mammographically and/or ultrasonographically established breast cancer. Materials and method: from September 1998 to August 1999, preoperative contrast-enhanced MR imaging of the breast was performed in 91 patients with lesions highly suggestive of malignancy (BIRADS IV and V) by clinical, mammographic, and/or ultrasonographic criteria. MR imaging findings were postsurgically correlated with other imaging, intraoperative and histopathologic results. Results: histopathologic analysis revealed 61 (66%) malignant and 31 (34%) benign lesions. In 63 (69%) of the 91 investigated patients, MR mammographies were classified as tumor suspect and in the remaining 28 (31%) cases as benign. The sensitivity, specificity and accuracy were 90%, 67% and 81% for contrast-enhanced MR imaging. Additional tumor manifestations (multifocal or multicentric disease, contralateral carcinoma) were found by MR imaging alone in 10 patients (11%). Conclusion: contrast-enhanced MR imaging may reveal unsuspected multifocal, multicentric or contralateral breast carcinoma that changes the surgical therapy if the intention is total tumor removal. The prognostic role of a potentially more radical surgical therapy on the basis of these findings is not clear. (orig.)

    Aim: The optimal acquisition time for staging colo-rectal carcinoma with a contrast enhanced multidetector CT colonography (CE CTC) has not yet been established. A dual phase with both arterial and portal venous acquisition has been proposed. The purpose of our study is to assess the value of single portal venous phase CE CTC in the preoperative staging of colo-rectal carcinoma. Materials and methods: Fifty two (30 M, 22 F; aged 35-82 years) consecutive patients with a histologically proven diagnosis of colo-rectal adenocarcinoma or a highly suspected colo-rectal cancer on conventional colonoscopy underwent a four-slice CE CTC. The procedure was performed 70 s (portal phase) after the intravenous bolus (3 ml/s) administration of 120 ml iodinated non-ionic contrast agent (370 mg iodine/ml). Scans were performed using the following parameters: 2.5 mm beam collimation, pitch 1.25, 120 kV, 200 mAs, rotation time 0.75 s. Images were reconstructed with an effective thickness of 3.2 mm at intervals of 1.6 mm. Two radiologists independently evaluated the depth of tumour invasion into the colo-rectal wall (T), regional lymph node involvement (N), and extracolonic metastases (M). Disagreement was resolved by means of a consensus decision. The pathological results served as the standard of reference. Assessment was made of sensitivity, specificity and accuracy, as well as positive and negative predictive values were assessed. Results: CE CTC correctly staged the pT of 52/56 (93%) and the N of 40/56 (71%) lesions, as well as properly identifying 13/14 (93%) extracolonic findings. Conclusion: The single portal venous phase CE CTC scanning protocol enables satisfactory preoperative assessment of T, N and M staging in patients with colo-rectal cancer.

    Full Text Available Microbially enhanced coalbed methane technology must be used to increase the methane content in mining and generate secondary biogenic gas. In this technology, the metabolic processes of methanogenic consortia are the basis for the production of biomethane from some of the organic compounds in coal. Thus, culture nutrition plays an important role in remediating the nutritional deficiency of a coal seam. To enhance the methane production rates for microorganism consortia, different types of nutrition solutions were examined in this study. Emulsion nutrition solutions containing a novel nutritional supplement, called dystrophy optional modification latex, increased the methane yield for methanogenic consortia. This new nutritional supplement can help methanogenic consortia form an enhanced anaerobic environment, optimize the microbial balance in the consortia, and improve the methane biosynthesis rate.

    The preoperative prognostic nutritional index (PNI) may forecast colorectal cancer (CRC) outcomes, but the evidence is not conclusive. Here, we retrospectively analyzed a cohort of patients from the Department of Surgical Oncology at the First Hospital of China Medical University (CMU-SO). We also conducted a meta-analysis of eleven cohort studies. Bayesian Information Criterion (BIC) was used to determine the optimal PNI cut-off values for classifying prognosis in the patients from the CMU-SO. The result from CMU-SO and meta-analysis both confirmed that low PNI was significantly associated with a poor prognosis and advanced TNM stages. Among the patients from the CMU-SO, the optimal cut-off values were "41-45-58" (PNI < 41, 41 ≤ PNI < 45, 45 ≤ PNI < 58, PNI ≥ 58), which divided patients into 4 stages. The BIC value for TNM staging combined with the PNI was smaller than that of TNM staging alone (-325.76 vs. -310.80). In conclusion, low PNI was predictive of a poor prognosis and was associated with clinicopathological features in patients with CRC, and the 41-45-58 four-stage division may be suitable for determining prognosis. PNI may thus provide an additional index for use along with the current TNM staging system to determine more accurate CRC prognoses.

    Myocardial scarring creates a substrate for reentrant circuits which can lead to ventricular tachycardia. In ventricular catheter ablation therapy, regions of myocardial scarring are targeted to interrupt arrhythmic electrical pathways. Low voltage regions are a surrogate for myocardial scar and are identified by generating an electro anatomic map at the start of the procedure. Recent efforts have focussed on integration of preoperative scar information generated from delayed contrast-enhanced MR imaging to augment intraprocedural information. In this work, we describe an initial feasibility study of integration of a preoperative MRI derived scar maps into a high-resolution mapping system to improve planning and guidance of VT ablation procedures.

    Objective This study was conducted to evaluate the effects of postoperative immune enhancing enteral nutrition on the immune system, inflammatory responses, and clinical outcome of patients undergoing major abdominal surgery. Methods This study was designed as a multicenter, prospective,randomized and controlled clinical trial. One hundred twenty-four patients undergoing major abdominal surgery were randomly assigned to receive either an immune enhancing enteral diet or an isocaloric and isonitrogenous control enteral diet for seven days. Enteral feeding was initiated 24 hours after surgery. Host immunity was evaluated by measuring levels of IgG, IgM, IgA, CD4, CD8, and CD4/CD8, and the inflammatory response was determined by assessing IL-1α, IL-2, IL-6, IL-10, and TNF-α levels. Infectious complications were also recorded. Results One hundred twenty patients completed the study and four patients were excluded. On postoperative day 9, among patients receiving an immune enhancing diet,IgG, IgA, CD4 and CD4/CD8 levels were significantly higher and TNF-α and IL-6 concentrations were significantly lower compared to the control group. Moreover, among patients receiving an immune enhancing diet, when comparing preoperation to day 9 postoperation levels, increases in IgA, CD4, and CD4/CD8 levels were significantly higher than in control patients and increases in TNF-α concentrations were significantly lower. No statistically significant differences were found between the two groups with regard to infectious complications.Conclusions Postoperative administration of immune enhancing enteral nutrition in patients undergoing major abdominal surgery can positively modulate postoperative immunosuppressive and inflammatory responses.

    Living renal donors undergo an extensive examination program. These examinations should be as safe, gentle, and patient friendly as possible. To compare computed tomography angiography (CTA) and an extensive magnetic resonance imaging (MRI) protocol without contrast agents to observations from nephrectomy in living renal donors and to evaluate whether noncontrast-enhanced MRI can replace CTA for vessel assessment in living renal donors. CTA and MRI results were compared to observations from nephrectomy, which served as the reference standard. Fifty-one potential kidney donors underwent imaging, and 31 donated a kidney. Comparisons in sensitivity, specificity, and accuracy were made with respect to the number of arteries, early branching, and the number of veins. Agreement was assessed using Cohen's kappa. The exact McNemar's test was used to test for statistically significant differences. In the assessment of more than one renal artery, the sensitivity and specificity of MRI and CTA were high and in perfect agreement compared to observations from surgery. The results for both MRI and CTA were as follows: (sensitivity 100%/specificity100%/accuracy 100%/Kappa = 1/P = 1). When comparing the ability to test for early branching we found, MRI: (sensitivity 33%/specificity 100%/accuracy 87%/Kappa = 0.45/P = 1) and CTA: (sensitivity 50%/specificity 100%/accuracy 90%/Kappa = 0.62/P = 1). When used to depict supernumerary veins, we found MRI: (sensitivity60%/specifivity100%/accuracy 93%/Kappa = 0.72/P = 1), whereas CTA showed: (sensitivity 40%/specificity 96%/accuracy 87% Kappa = 0.43/P = 1). In conclusion, an optimized MRI protocol that includes noncontrast-enhanced magnetic resonance angiography can be substituted for CTA for preoperative assessment of the renal vessels before living donor nephrectomy.

    Multimodal rehabilitation programs are perioperative standardized strategies with the objective of improving patient recovery, and decreasing morbidity, hospital stay and health cost. The nutritional aspect is an essential component of multimodal rehabilitation programs and therefore nutritional screening is recommended prior to hospital admission, avoiding pre-surgical fasting, with oral carbohydrate overload and early initiation of oral intake after surgery. However, there are no standardized protocols of diet progression after pancreatic surgery. A systematic review was been performed of papers published between 2006 and 2016, describing different nutritional strategies after pancreatic surgery and its possible implications in postoperative outcome. The studies evaluated are very heterogeneous, so conclusive results could not be drawn on the diet protocol to be implemented, its influence on clinical variables, or the need for concomitant artificial nutrition.

    The prognostic value of the dynamic contrast-enhanced (DCE) MRI perfusion and its histogram analysis-derived metrics is not well established for high-grade glioma (HGG) patients. The aim of this prospective study was to investigate DCE perfusion transfer coefficient (K{sup trans}), vascular plasma volume fraction (v{sub p}), extracellular volume fraction (v{sub e}), reverse transfer constant (k{sub ep}), and initial area under gadolinium concentration time curve (IAUGC) as predictors of progression-free (PFS) and overall survival (OS) in HGG patients. Sixty-nine patients with suspected anaplastic astrocytoma or glioblastoma underwent preoperative DCE-MRI scans. DCE perfusion whole tumor region histogram parameters, clinical details, and PFS and OS data were obtained. Univariate, multivariate, and Kaplan-Meier survival analyses were conducted. Receiver operating characteristic (ROC) curve analysis was employed to identify perfusion parameters with the best differentiation performance. On univariate analysis, v{sub e} and skewness of v{sub p} had significant negative impacts, while k{sub ep} had significant positive impact on OS (P < 0.05). v{sub e} was also a negative predictor of PFS (P < 0.05). Patients with lower v{sub e} and IAUGC had longer median PFS and OS on Kaplan-Meier analysis (P < 0.05). K{sup trans} and v{sub e} could also differentiate grade III from IV gliomas (area under the curve 0.819 and 0.791, respectively). High v{sub e} is a consistent predictor of worse PFS and OS in HGG glioma patients. v{sub p} skewness and k{sub ep} are also predictive for OS. K{sup trans} and v{sub e} demonstrated the best diagnostic performance for differentiating grade III from IV gliomas. (orig.)

    To retrospectively evaluate relative enhancement (RE) in the hepatobiliary phase of gadoxetic acid disodium-enhanced magnetic resonance (MR) imaging as a preoperative estimation of future remnant liver (FRL) function in a patients who underwent portal vein embolization (PVE). In 53 patients, the correlation between the indocyanine green clearance (ICG-K) and RE imaging was analyzed before hepatectomy (first analysis). Twenty-three of the 53 patients underwent PVE followed by a repeat RE imaging and ICG test before an extended hepatectomy and their results were further analyzed (second analysis). Whole liver function and FRL function were calculated on the MR imaging as follows: RE x total liver volume (RE Index) and FRL-RE x FRL volume (Rem RE Index), respectively. Regarding clinical outcome, posthepatectomy liver failure (PHLF) was evaluated in patients undergoing PVE. Indocyanine green clearance correlated with the RE Index (r = 0.365, p = 0.007), and ICG-K of FRL (ICG-Krem) strongly correlated with the Rem RE Index (r = 0.738, p < 0.001) in the first analysis. Both the ICG-Krem and the Rem RE Index were significantly correlated after PVE (r = 0.508, p = 0.013) at the second analysis. The rate of improvement of the Rem RE Index from before PVE to after PVE was significantly higher than that of ICG-Krem (p = 0.014). Patients with PHLF had a significantly lower Rem RE Index than patients without PHLF (p = 0.023). Relative enhancement imaging can be used to estimate FRL function after PVE.

    The aim of this prospective study was to compare the diagnostic performance of 64-row MDCT and gadoxetic-acid-enhanced MRI at 3.0 T in patients with colorectal liver metastases in correlation with histopathological findings. Lesions detected at MDCT and MRI were interpreted by three blinded readers and compared with histopathological workup as the term of reference. Two subgroups of lesions were additionally evaluated: (1) metastases smaller than 10 mm and (2) lesions in patients with and without steatosis of the liver, assessed histopathologically. Surgery and histopathological workup revealed 81 colorectal liver metastases in 35 patients and diffuse metastatic involvement in 3 patients. In a lesion-by-lesion analysis, significant sensitivity differences could only be found for reader 1 (P = 0.035) and reader 3 (P = 0.003). For segment-based evaluation, MRI was more sensitive only for reader 3 (P = 0.012). The number of false-positive results ranged from 3 to 12 for MDCT and 8 to 11 for MRI evaluation. In the group of small lesions, the sensitivity differed significantly between both methods (P = 0.003). In patients with hepatic steatosis, MRI showed a trend toward better performance than MDCT, but without statistical performance. The 3.0-T MRI with liver-specific contrast agents is the preferred investigation in the preoperative setting, especially for the assessment of small colorectal liver metastases. (orig.)

    Background parenchymal enhancement (BPE) on breast magnetic resonance imaging (MRI) may either obscure or mimic malignancy. We evaluated the impact of BPE on the diagnostic performance of pre-operative MRI in breast cancer patients, and how second-look ultrasound (US) can help in guiding patient management. Two hundred fifty-three breast cancer patients with pre-operative MRI were included. In moderate or marked BPE, abnormal interpretation rate (38.9% vs. 12.2%) and biopsy rate (27.8% vs. 8.3%) were higher, and specificity (64.7% vs. 89.8%) was lower, compared with minimal or mild BPE (all p abnormal interpretation rate, additional biopsy rate and decreased specificity. Second-look US was useful in visualization of MRI-detected additional suspicious lesions, regardless of BPE.

    Nutrition appeared somewhat late on the scene in the I.B.P. projects in the U.K., but eventually it occupied an integral part of many of the H.A. (human adaptability) investigations. The nutritional data obtained in the studies of isolated and nearisolated communities in Tristan da Cunha and in New Guinea provided information of wide nutritional significance. There were also detailed and extensive studies in Israel which, similarly to those in New Guinea, attempted to relate nutritional factors to enviroment, working conditions, and physical fitness. Some extraordinarily low energy intakes found in Ethiopians have induced much speculation on the extent which man can adequately adapt to restricted food supplies. Interesting nutritional observations, of general importance, have also arisen from results obtained on such disparate groups as Glasgow adolescents, Tanzanian and Sudanese students, children in Malawi and vegans in the U.K.

    Full Text Available OBJECTIVES: The aim was (i to evaluate the accuracy of equilibrium-phase high spatial resolution (EP contrast-enhanced magnetic resonance angiography (CE-MRA at 1.5T using a blood pool contrast agent for the preoperative evaluation of deep inferior epigastric artery perforator branches (DIEP, and (ii to compare image quality with conventional first-pass CE-MRA. METHODS: Twenty-three consecutive patients were included. All patients underwent preoperative CE-MRA to determine quality and location of DIEP. First-pass imaging after a single bolus injection of 10 mL gadofosveset trisodium was followed by EP imaging. MRA data were compared to intra-operative findings, which served as the reference standard. RESULTS: There was 100% agreement between EP CE-MRA and surgical findings in identifying the single best perforator branch. All EP acquisitions were of diagnostic quality, whereas in 10 patients the quality of the first-pass acquisition was qualified as non-diagnostic. Both signal- and contrast-to-noise ratios were significantly higher for EP imaging in comparison with first-pass acquisitions (p<0.01. CONCLUSIONS: EP CE-MRA of DIEP in the preoperative evaluation of patients undergoing a breast reconstruction procedure is highly accurate in identifying the single best perforator branch at 1.5Tesla (T. Besides accuracy, image quality of EP imaging proved superior to conventional first-pass CE-MRA.

    Many candidates for kidney transplantation need to undergo vessel examination before the transplantation procedure. To identify the optimal preoperative modality for the examination of vessel status without the use of contrast agents in kidney transplant candidates. Fifty-three consecutive patients were examined and 31 patients were transplanted. Ultrasonography (US), non-contrast-enhanced computed tomography (NCCT), and non-contrast-enhanced magnetic resonance angiography (NCMRA) were compared using inspection during kidney transplantation (TX) as a reference standard. The sensitivity and specificity to severe arteriosclerotic changes and the accuracy were calculated. Kappa statistics were used to assess the agreement between TX and the different examination modalities, and McNemar's test was used to test for significant differences. US had higher sensitivity (1.0) and better agreement with observations from surgery (k = 0.89) than both NCCT (sensitivity = 0.60; k = 0.72) and NCMRA (sensitivity = 0.20; k = 0.30). No significant difference was found between TX and US (P = 0.3173) or TX and NCCT (P = 0.1573), but there was a significant difference between TX and NCMRA (P = 0.0455). US was inconclusive in 20% of cases, and the internal iliac artery could not be visualized in 69% of cases. Either US or NCCT can be used as the preferred preoperative imaging modality to examine vessel status before kidney transplantation, but a combination of the two is preferable. NCMRA should not be used as the sole imaging modality for preoperative imaging before kidney transplantation because of its low sensitivity in detecting severe arteriosclerotic disease without the presence of stenosis. © The Foundation Acta Radiologica 2014.

    This review presents current knowledge regarding the rationale and efficacy of nutrition as an ergogenic aid to enhance the effects of exercise and training in chronic obstructive pulmonary disease (COPD). Altered body composition and skeletal muscle dysfunction in COPD suggest that exercise capacity can be targeted via several metabolic routes. Muscle metabolic alterations in COPD include a reduced oxidative metabolism and enhanced susceptibility for oxidative stress. Muscle wasting may be associated with deficiencies of vitamin D and low branched-chain amino acid levels. Exercise training is of established benefit in COPD but clear-cut clinical trial evidence to support the performance enhancing effect of nutritional intervention is lacking. One randomized controlled trial suggested that augmentation of training with polyunsaturated fatty acids may improve exercise capacity. Conflicting results are reported on dietary creatine supplementation in patients with COPD receiving pulmonary rehabilitation and results from acute intervention studies do not directly imply long-term effects of glutamate or glutamine supplementation as an ergogenic aid in COPD. Recent data indicate that not only muscle but also visceral fat may be an important additional target for combined nutrition and exercise intervention in COPD to improve physical performance and decrease cardiometabolic risk. There is a clear need for adequately powered and controlled intervention and maintenance trials to establish the role of nutritional supplementation in the enhancement of exercise performance and training and the wider management of the systemic features of the disease.

    To evaluate stable xenon-enhanced CT cerebral blood flow with balloon test occlusion as a predictor of stroke risk in internal carotid artery sacrifice. Abrupt internal carotid artery occlusion was performed by surgical or endovascular means below the origin of the ophthalmic artery in 31 normotensive patients who were assessed preoperatively by a 15-minute clinical balloon test occlusion followed by an internal carotid artery-occluded xenon CT cerebral blood flow study. One patient, who passed the clinical test occlusion but exhibited regions of cerebral blood flow less than 30 mL/100 g per minute on the occlusion xenon CT cerebral blood flow study went on to have a fatal stroke corresponding exactly to the region of assessment. Neuroimaging demonstrated possible flow-related infarctions, which subsequently developed in three patients. Two patients were asymptomatic, and one patient was left with a mild residual hemiparesis. Our protocol provided a statistically significant reduction in subsequent infarction rate and infarction-related death rate when compared with a control group of normotensive abrupt internal carotid artery occlusion patients who did not undergo any preoperative stroke-risk assessment (reported in the literature). The estimated false-negative rate for our preoperative assessment protocol ranged from 3.3% to 10% depending on the assessment of the cause of the three potentially flow-related infarctions. Although life-threatening major vascular territory infarctions have been avoided, our protocol is less sensitive to changes predicting smaller, often minimally symptomatic, vascular border zone infarctions and does not predict postoperative thromboembolic strokes. 94 refs., 5 figs., 4 tabs.

    Background Microvascular decompression is an etiological strategy for the therapy of trigeminal neuralgia (TN). Preoperative identification of neurovascular compression, therefore, could have an impact on the determination of appropriate treatment for TN. Purpose To evaluate the value of contrast-enhanced and unenhanced three-dimensional (3D) time-of-flight (TOF) MR angiography in the visualization of neurovascular relationship in patients with TN. Material and Methods Thirty-seven patients with unilateral TN underwent unenhanced and contrast-enhanced 3D TOF MR angiography with a 3.0-T MR system. Images were reviewed by a radiologist blinded to clinical details. Vascular contact with the trigeminal nerve was identified, and the nature of the involved vessels (artery or vein) was determined. All patients underwent microvascular decompression. Results In 37 patients with TN, contrast-enhanced 3D TOF MR angiography identified surgically verified neurovascular contact in 35 of 36 symptomatic nerves, and there was no false-positive. Based on surgical findings, the sensitivity of MR imaging was 97.2% and specificity 100%. The nature of the offending vessel was correctly identified in 94.4% of the patients by using the combination of contrast-enhanced and unenhanced MR angiography. Conclusion Contrast-enhanced 3D TOF MR angiography is useful in the detection of vascular contact with the trigeminal nerve in patients with TN, and this MR imaging in combination with unenhanced MR angiography could help in the identification of the nature of the responsible vessels

    This study aimed to determine preoperative predictors of early (huge (≥10 cm) HCC, with special emphasis on the importance of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and prognostic nutrition index (PNI). Between 2000 to 2013, 166 patients underwent LR for huge HCC. Optimal cut-offs for alpha fetoprotein (AFP), NLR, PLR, and PNI were determined by plotting the receiver operator curves (ROC) in predicting early mortality and utilizing the Youden index. The 30-day/in-hospital postoperative mortality rate was 4.2%. The 5-year overall survival (OS) and the 5-year recurrence-free survival (RFS) was 43% and 24%, respectively. Early mortality from disease recurrence occurred in 35 of 159 (22%) patients. Multivariate analyses demonstrated that tumor rupture and high AFP (>1,085 ng/ml) were independent preoperative predictors of early mortality after LR for HCC, and both a low PNI (huge HCC. J. Surg.

    The safety of gadolinium-ethoxybenzyl-diethylenetriamine-pentaacetic-acid (Gd-EOB-DTPA) has been confirmed, but more study is needed to assess the diagnostic accuracy of Gd-EOB-DTPA-enhanced magnetic resonance imaging (MRI) in patients with a hepatocellular carcinoma (HCC) for whom surgical treatment is considered or with a metastatic hepatoma. Research is also needed to examine the rate of detection of hepatic lesions compared to multi-detector computed tomography (MDCT), which is used most frequently to localize and characterize a HCC. Gd-EOB-DTPA-enhanced MRI and iodine-enhanced MDCT imaging were compared for the preoperative detection of focal liver lesions. The clinical usefulness of each method was examined. The current study enrolled 79 patients with focal liver lesions who preoperatively underwent MRI and MDCT. In these patients, there was less than one month between the two diagnostic modalities. Imaging data were taken before and after contrast enhancement in both methods. To evaluate the images, we analyzed the signal-to-noise ratio (SNR) and the contrast-to-noise ratio (CNR) in the lesions and the liver parenchyma. To compare the sensitivity of the two methods, we performed a quantitative analysis of the percentage signal intensity of the liver (PSIL) on a high resolution picture archiving and communication system (PACS) monitor (paired-samples t-test, p DTPA-enhanced MRI findings and the iodine-enhanced MDCT by using an adjusted x2 test. The SNRs, CNRs, and PSIL all had a greater detection rate in Gd-EOB-DTPA enhanced MRI than in iodine-enhanced MDCT. Hepatocyte-selective uptake was observed 20 minutes after the injection in the focal nodular hyperplasia (FNH, 9/9), adenoma (9/10), and highly-differentiated HCC (grade G1, 27/30). Rim enhancement was detected in all metastases (30/30). During the arterial and the delayed phases, good overall agreement between the gadoxetic-acid-enhanced MR and CT was observed (x2 test, p DTPA-enhanced MRI had a higher

    To compare vascular measurements to determine stent types and configurations for abdominal endovascular aneurysm repair (EVAR) by comparing results of contrast material-enhanced computed tomographic (CT) angiography and nonenhanced magnetic resonance (MR) angiography. This prospective study was institutional review board approved, and all patients provided written informed consent. Fifty patients (45 men and five women; mean age, 76.0 years) admitted for elective abdominal EVAR underwent preoperative abdominal CT angiography (triplanar reformatted images; section thickness of 1-3 mm) and nonenhanced MR angiography (triplanar two-dimensional single-shot turbo field-echo images; section thickness of 6 mm). Two observers independently completed standard measurement and device selection forms for endovascular stent planning for CT and MR angiography. Pearson and intraclass correlation coefficients were calculated to evaluate intermodality and interobserver differences. No significant difference was found in aortic neck diameter (observer 1: CT, 18.5 mm; MR, 19.0 mm; P = .43) (observer 2: CT, 19.6 mm; MR, 19.3 mm; P = .59), aortic neck diameter 15 mm distal to the lowest renal artery (observer 1: CT, 19.2 mm; MR, 19.2 mm; P = .38) (observer 2: CT, 19.6 mm; MR, 19.6 mm; P = .91), aortic neck length (observer 1: CT, 43.6 mm; MR, 43.6 mm; P = .85) (observer 2: CT, 44.4 mm; MR, 44.0 mm; P = .93), or other key vascular measurements (P = .23-.99) for preoperative planning. These included aneurysm diameter, lowest renal artery to aortic bifurcation length, aortic bifurcation diameter, common iliac artery diameters, external iliac artery diameters, length between orifices of lower renal and internal iliac arteries, and iliac artery sealing length. CT and MR angiography measurements showed very strong correlation (r = 0.92-0.99). Intraclass correlation coefficients between observers ranged from 0.90 to 0.98. Stent types and configurations determined with CT measurements remained

    Objective Our objective was to compare the accuracy of preoperative positron emission tomography (PET)/computed tomography (CT) and contrast-enhanced CT (CECT) in detecting cervical nodal metastases in patients treated with neck dissection and to scrutinize the ability of each modality to determine nodal stage. Study Design Case series with chart review. Setting Montefiore Medical Center, Bronx, New York. Subjects and Methods Patients who underwent neck dissection at our institution for primary treatment of head and neck squamous cell carcinoma (HNSCC) and had received preoperative PET/CT and CECT were included in this study. Imaging studies were reinterpreted by 3 specialists within the field and compared for interreader agreement. Concordance between radiology and histopathology was measured using neck levels and sides, along with patient nodal stage. Sensitivity, specificity, accuracy, positive predictive value, negative predictive value, and agreement coefficients were calculated. Results Seventy-three patients were included in the study. Sensitivity was 0.69 and 0.94 (level and side) for PET/CT vs 0.53 and 0.66 for CECT ( P = .056, P = .001). Specificity was 0.86 and 0.56 for PET/CT vs 0.91 and 0.76 for CECT ( P = .014, P = .024). No significant difference was found in overall accuracy ( P = .33, P = .88). The overall agreement percentages between N stage called by imaging modality and pathology were 52% and 55% for PET/CT and CECT, respectively. Conclusion No significant difference in sensitivity was found between PET/CT and CECT. CECT was found to have superior specificity compared with PET/CT. The information gleaned from each modality in the pretreatment evaluation of HNSCC appears to be complementary.

    Full Text Available The aim of the study was to detect if gadolinium-enhanced renal magnetic reso-nance angiography (MRA can replace conventional angiography in imaging vascular anatomy in potential living renal donors and compare with surgical findings. MR imaging (MRI and breath-hold three-dimensional gadolinium-enhanced MRA of kidneys were done for 60 conse-cutive patients for whom successful nephrectomy was done. MRA findings were compared with the findings of nephrectomy. MRI and MRA identified 28 out of 60 patients with normal arterial and venous anatomy, and concordance was found at surgery in 27 of these patients. Vascular anomalies were depicted on MRI in 32 patients, with concordance at surgery in 27 patients. Re-garding arterial anomalies, the MRA had a sensitivity of 89.3%, a specificity of 94.0% and an accuracy of 90.8%. For venous anomalies, the sensitivity was 98.5%, specificity was 100% and accuracy was 98.6%. In conclusion, gadolinium-enhanced MRA of the kidneys can replace con-ventional angiography as a safe and accurate modality for the assessment of potential living renal donors.

    Purpose: The purpose of this study was to evaluate the blood pool contrast agent gadofosveset for MR angiography (MRA) of the renal vasculature in living kidney donors (LKD). Materials and Methods: Of the 28 consecutive potential LKDs (13 men, 15 women; mean age 55.14 years {+-} 11.97) initially included in this prospective study, 20 patients underwent surgery and were considered for further evaluation. 7 acquisitions of a 3D T1-weighted FLASH sequence were performed following administration of gadofosveset for the assessment of the vascular anatomy and collecting system at predefined time points at 1.5 T. All MR exams were prospectively analyzed by 2 radiologists in consensus mode prior to surgery. In addition, ROI-based relative SNR measurements were performed in the vena cava inferior and abdominal aorta. Results: MR image acquisition was completed in all 20 potential living donors. In 8 donors an additional CT scan was available for further comparison with the collateral anatomy, resulting in a total of 28 analyzed kidneys. MRA disclosed 36 renal arteries, since 8 accessory arteries were found in 8 subjects. One accessory artery and one case of fibromuscular dysplasia were missed by MRA. The venous anatomy and the collecting system were assessed correctly with MRI. In addition, MRI diagnosed two renal cell carcinomas. The overall sensitivity and positive predictive value of gadofosveset-enhanced MRI on a per kidney basis were 92.9 % and 100 %, respectively. Conclusion: Gadofosveset enables accurate evaluation of potential LKDs. (orig.)

    Human consumption of flaxseed is increasing due to its health benefit properties and extrusion processes can enhance its nutritional quality. Extruded flaxseed meal (EFM) obtained in a pilot plant was characterized and incorporated in flour mixes and cereal-based bars to demonstrate its nutritious usefulness. Amino acid content was not affected by extrusion and, despite lysine was the limitating amino acid, the chemical score (CS) was 83 %. Thiamin and riboflavin decreased slightly as consequence of extrusion, phytic acid did not change and trypsin inhibitor activity was undetectable. Proximate composition and nutritional quality determined by biological and chemical indexes were compared among EFM, flour mixes (FM) and cereal bars (CB). They presented high protein levels (26, 20 and 17 %, respectively), good biological value (BV) (80, 79 and 65, respectively), acceptable true protein digestibility (TD) (73, 79 and 78, respectively), and high dietary fiber (33, 20.5 and 18 %, respectively). The ratio of ω6:ω3 for CB was within the WHO/FAO recommendations. These results open a new venue for the usefulsess of nutritious/healthy extruded flaxseed flours into ready-to-eat cereal-based products with improved nutritional quality.

    Magnetic resonance (MR) venography and computed tomographic (CT) venography are suited for displaying the convexity veins that drain the medial and lateral surfaces of the brain hemispheres. However, such is not the case for the bridging veins of the skull base. Technical factors prevent contrast material-enhanced MR or CT images obtained in standard axial, coronal, and sagittal planes from fully displaying the curved pathways of these clinically important venous structures. This limitation can be overcome by using a reconstruction technique that depicts these venous structures and their interconnections. Curved and multiplanar reformatted images that distill the important venous features often require knowledgeable manipulation of source images by an operator who is familiar with numerous venous variants and their surgical implications. The normal anatomy of the draining veins is detailed-anatomy that radiologists must master before they can show the surgeon the important venous anatomy that is often missing at standard imaging; this information will foster better communication between radiologists and their surgical colleagues. As a practical matter, the skull base veins are arbitrarily subdivided into those that are at greatest risk with the pterional approach and the subtemporal approach, respectively. These approaches can be expanded to define connections between the superficial venous system and the other valveless venous networks that drain the deep portions of the cerebral hemisphere, the scalp, face, muscles of the neck, diploë of the skull, and meninges. As radiologists gain experience, their image interpretations should mature beyond simple analysis of the primary hemodynamic changes induced by intraoperative sacrifice or injury.

    To retrospectively investigate whether background parenchymal enhancement (BPE) of the contralateral breast on preoperative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is associated with therapeutic outcomes following neoadjuvant chemotherapy (NAC) in unilateral invasive breast cancer. The institutional review board approved this study, and informed consent was waived. Between 2009 and 2011, 93 women with unilateral invasive breast cancer (43 premenopausal women who performed pre-NAC MRI between days 7 and 20 of the menstrual cycle and 50 postmenopausal women) underwent NAC with pre- and post-NAC DCE-MRI before surgery. MRI features (BPE [minimal, mild, moderate, marked] of the contralateral breast, lesion size and number, lesion kinetics, and changes in lesion size) and clinicopathologic features were analyzed. Patients were grouped according to BPE category (high [moderate or marked] or low [minimal or mild]). Cox regression modeling was used to determine associations between MRI features and recurrence-free survival (RFS) after controlling for clinicopathologic variables. The mean follow-up period was 48.2 months. Twenty-three recurrences occurred (2 ipsilateral breasts, 6 regional, and 15 distant). On multivariate analysis, high BPE on pre-NAC MRI (hazard ratio [HR] = 3.851, P = 0.006) and triple-negative cancer (HR = 3.192, P = 0.002) were independent factors associated with worse RFS. A greater reduction of lesion size on post-NAC MRI (HR = 0.984, P = 0.021) was associated with better RFS. High BPE on pre-NAC MRI is significantly associated with worse RFS in an NAC setting. This study suggests that BPE on pre-NAC DCE-MRI may have potential as a predictor of long-term outcomes in breast cancer patients who undergo NAC.

    A relatively unexplored method to enhance the sensory and nutritional properties of chocolate is to use plant polyphenols. In this study, a low cost agricultural waste product - mangosteen (Garcinia mangostana Linn.) pericarp - was added as powder in graded amounts (1%, 2% and 3%w/w) to dark and compound chocolates during the mixing stage and evaluated. The particle size distributions of the chocolates were mostly within 30 μm and the chocolates displayed a homogeneous morphology. The polyphenols (procyanidins and xanthones) in mangosteen pericarp powder were also stable to simulated chocolate processing. The 3% pericarp powder concentration significantly expanded the bioactive profile and total phenolic content (13% in dark chocolates and 50% in compound chocolates) compared to their plain counterparts without affecting sensory qualities. Such low cost plant polyphenols could enhance the bioactive and flavor profile of chocolates, especially in low cocoa content compound chocolates.

    Mixed-methods research investigated the work motivation of paraprofessional community nutrition educators (CNEs) delivering a long-running public health nutrition program. In interviews, CNEs (n = 9) emphasized "freedom," supportive supervision, and "making a difference" as key sources of motivation. Community nutrition educator surveys (n = 115) confirmed high levels of autonomy, which was associated with supervisors' delegation and support, CNE decision-making on scheduling and curricula, and job satisfaction. Supervisors (n = 32) rated CNEs' job design as having inherently motivating characteristics comparable to professional jobs. Supervisory strategies can complement job design to create structured, supportive contexts that maintain fidelity, while granting autonomy to paraprofessionals to enhance intrinsic work motivation.

    Amla (Indian gooseberry) and its processed products are rich source of vitamin C, phenols, dietary fibre and antioxidants. In contrast, ice cream is a poor source of these phytochemicals and antioxidants; therefore, the present investigation was undertaken to enhance the functional properties and nutritional quality of ice cream with the incorporation of processed amla. Ice cream was prepared using amla shreds, pulp, preserve and candy at 5 to 20 % and powder at 0.5 to 2.0 % levels in ice cream mix prior to freezing. Inclusion of amla products at augmented levels resulted in significant changes in physico-chemical properties and phytochemical content of ice cream. The total solids decreased on addition of shreds and pulp and increased with preserve, candy and powder in ice cream at increasing levels. The functional constituents i.e. fibre, total phenols, tannins, ascorbic acid and antioxidant activity increased with greater level of inclusion. Incorporation of processed amla raised the melting resistance of ice cream and decreased the overrun. The samples with 5 % shreds and pulp, 10 % preserve and candy and 0.5 % powder were found to have highest overall acceptability scores. Inclusion of amla in all the forms i.e. shreds, pulp, preserve, candy and powder enhanced the functional properties and nutritional value of ice cream.

    Full Text Available Tomatoes are a unique functional food and a natural reservoir of many health promoting nutrients, antioxidants, dietary fibres and chemopreventive nutraceuticals. They are particularly rich in lycopene which has been associated with the prevention of cardiovascular disease and cancers of the prostate and the gastrointestinal tract. As an important vegetable worldwide, tomatoes have drawn the attention of many researchers. Thus, numerous investigations have been conducted and various improvement strategies applied for enhancing the functionality of this medicinal food geared towards disease prevention, global health and well-being. Molecular breeding has produced a number of tomato lines with enhanced levels of lycopene, β-carotene and xanthophylls. Over expression of certain genes have generated tomato fruits with enhanced ascorbic acid levels and folate accumulation up to 25-fold. Plant hormone technology has been used to enhance tomato minerals, antioxidant vitamins, lycopene, β-carotene, flavonoids and phenolic compounds in tomato fruit tissues. Manipulation in soilless culture solutions is valuable for enhancing the antioxidative capacity of tomatoes, vitamin C, flavonoids, lycopene, and β-carotene in fresh fruits. In addition, the spraying of nutrients, such as potassium, in field conditions has a strong stimulatory effect on lycopene contents of tomatoes. Transgenic strategies are also being adopted. These strategies offer a rapid way to introduce desirable traits into the phenotype and differ from other approaches in that novel genetic information is introduced directly into the plant’s genome. An important and current trend in the improvement of functional foods is to shift from enhancing single nutritional compounds towards enhancing multiple nutrients and phytochemicals in order to harness their synergistic interactions. This could be achieved by the use of strategies having pleitropic effects such as bioregulators, multigene

    Fourteen infants requiring long-term total parenteral nutrition but able to tolerate small quantities of enteral feedings were randomized into carnitine treatment and placebo control groups. All infants had received nutritional support devoid of carnitine. Plasma carnitine levels and observed plasma lipid indices were not different before supplementation. Under standardized, steady-state conditions, 0.5 g/kg fat emulsion (intralipid) was administered intravenously over 2 hours both before and after infants received 7 days of continuous nasogastric or gastric tube L-carnitine (50 mumol/kg/day) or placebo. Plasma triglyceride, free fatty acid, acetoacetate, beta-hydroxybutyrate, and carnitine concentrations were observed at 0 (start of lipid infusion), 2, and 4 hours for pre- and post-treatment periods, and in addition at 6 and 8 hours after carnitine supplementation. Infants receiving carnitine had significantly greater beta-hydroxybutyrate plasma concentrations (P less than 0.05) and carnitine (P less than 0.001) at 0, 2, 4, 6, and 8 hours, and greater plasma acetoacetate concentrations (P less than 0.05) at 2, 4, 6, and 8 hours, compared with controls. Twenty-four-hour urinary carnitine excretion was very low for both groups before supplementation; after supplementation, excretion was higher (P less than 0.05) in the carnitine group. No significant differences were found between groups for plasma triglyceride or free fatty acid concentrations at any observation period. This study demonstrated enhanced fatty acid oxidation, as evidenced by increased ketogenesis, with L-carnitine supplementation in infants receiving long-term total parenteral nutrition.

    The prevalence of malnutrition or the risk of malnourishment is high among orthogeriatric patients and a poor nutritional status is associated with a negative outcome. A comprehensive management of preoperative and postoperative nutritional and fluid intake in these patients can help to improve the situation. The management includes identification of patients affected, a thorough assessment of the nutritional status, work-up of possible underlying causes, documentation of nutritional and fluid intake and, most importantly, procedures to improve the preoperative and postoperative nutritional situation. This article gives an overview of the recently updated recommendations on nutritional management in orthogeriatric patients as published by the orthogeriatric working group of the German Geriatric Society.

Polyphenols are phytochemicals that appear to have chemical properties that provide valuable health benefits when ingested. In particular, experiments have suggested that grape seed proanthocyanidins, oligomers of the catechin family of polyphenols, may have health benefits, possibly due to their capacity to be oxidized. Two-dimensional gel proteomics technology identified specific rat brain proteins that were differentially affected after ingestion of grape seed extract. Beneficial changes in the expression of these proteins were observed relative to changes seen in the brains of Alzheimer disease patients at autopsy and of transgenic mouse models of dementia. These findings were consistent with the hypothesis that grape seed polyphenols may have neuroprotective activity. Previous experiments showed that grape seed extract was significantly chemopreventive in a rat model of breast cancer, but this depended on the specific diet in which the grape seed was administered. Thus, phytochemicals such as polyphenols may have health benefits in mammalian tissues unrelated to classical nutritional deficiency models. This report illustrates how experimental approaches that combine proteomics technologies with a dietary intervention with specific phytochemicals in normal animals can enhance studies on cancer prevention and treatment.

    Full Text Available Background: Adequate nutrient supply is essential for optimal postnatal growth in very low birth weight (VLBW, birth weight<1,500 g infants. Early growth may influence the risk of metabolic syndrome later in life. Objective: To evaluate growth and blood metabolic markers (adiponectin, leptin, and insulin-like growth factor-1 (IGF-1 in VLBW infants participating in a randomized nutritional intervention study. Design: Fifty VLBW infants were randomized to an enhanced nutrient supply or a standard nutrient supply. Thirty-seven infants were evaluated with growth measurements until 2 years corrected age (CA. Metabolic markers were measured at birth and 5 months CA. Results: Weight gain and head growth were different in the two groups from birth to 2 years CA (weight gain: pinteraction=0.006; head growth: pinteraction=0.002. The intervention group improved their growth z-scores after birth, whereas the control group had a pronounced decline, followed by an increase and caught up with the intervention group after discharge. At 5 months CA, adiponectin concentrations were higher in the intervention group and correlated with weight gain before term (r=0.35 and nutrient supply (0.35≤r≤0.45. Leptin concentrations correlated with weight gain after term and IGF-1 concentrations with length growth before and after term and head growth after term (0.36≤r≤0.53. Conclusion: Enhanced nutrient supply improved early postnatal growth and may have prevented rapid catch-up growth later in infancy. Adiponectin concentration at 5 months CA was higher in the intervention group and correlated positively with early weight gain and nutrient supply. Early nutrition and growth may affect metabolic markers in infancy.Clinical Trial Registration (ClinicalTrials.gov no.: NCT01103219

    Serum albumin has traditionally been used as a quantitative measure of a patient’s nutritional status because of its availability and low cost. While malnutrition has a clear definition within both the American and European Societies for Parenteral and Enteral Nutrition clinical guidelines, individual surgeons often determine nutritional status anecdotally. Preoperative albumin level has been shown to be the best predictor of mortality after colorectal cancer surgery. Specifically in colorectal surgical patients, hypoalbuminemia significantly increases the length of hospital stay, rates of surgical site infections, enterocutaneous fistula risk, and deep vein thrombosis formation. The delay of surgical procedures to allow for preoperative correction of albumin levels in hypoalbuminemic patients has been shown to improve the morbidity and mortality in patients with severe nutritional risk. The importance of preoperative albumin levels and the patient’s chronic inflammatory state on the postoperative morbidity and mortality has led to the development of a variety of surgical scoring systems to predict outcomes efficiently. This review attempts to provide a systematic overview of albumin and its role and implications in colorectal surgery.

    The objective of this study was to evaluate the effect of irrigation with yeasts (Debaryomyces hansenii var. Fabry, Yarowia lipolytica YIBCS002, Yarowia lipolytica var. BCS and Candida pseudointermedia) on the final nutritional content of hydroponic green maize fodder (Zea Zea mays L.), applied at different fodder growth stages (1. seed-seedling stage, 2. seedling-plant 20cm, 3. during all the culture). Irrespective of the fodder growth stages at which they were applied, all yeasts tested enhanced the content of raw protein, lipids, ash, moisture and energy. The percentage of electrolytes (Na, K, Cl, sulphates, Ca and Mg) showed different responses depending on the kind of yeast applied; D. hansenii exhibited the highest increment in all electrolytes, except for phosphorous. We conclude that the addition of yeasts belonging to the genera Debaryomyces, Candida and Yarowia to the irrigation solution of hydroponic systems enhances the nutrient content of green fodder. This kind of irrigation can be applied to generate high commercial value cultures in limited spaces. Copyright © 2014 Asociación Argentina de Microbiología. Publicado por Elsevier España, S.L.U.

    Meeting the food demands and ensuring nutritional security of the ever increasing global population in the face of degrading natural resource base and impending climate change is the biggest challenge of the twenty first century. The consequences of mineral/micronutrient deficiencies or the hidden hunger in the developing world are indeed alarming and need urgent attention. In addressing the problems associated with mineral/micronutrient deficiency, grain legumes as an integral component of the farming systems in the developing world have to play a crucial role. For resource-poor populations, a strategy based on selecting and/or developing grain legume cultivars with grains denser in micronutrients, by biofortification, seems the most appropriate and attractive approach to address the problem. This is evident from the on-going global research efforts on biofortification to provide nutrient-dense grains for use by the poorest of the poor in the developing countries. Towards this end, rapidly growing genomics technologies hold promise to hasten the progress of breeding nutritious legume crops. In conjunction with the myriad of expansions in genomics, advances in other 'omics' technologies particularly plant ionomics or ionome profiling open up novel opportunities to comprehensively examine the elemental composition and mineral networks of an organism in a rapid and cost-effective manner. These emerging technologies would effectively guide the scientific community to enrich the edible parts of grain legumes with bio-available minerals and enhancers/promoters. We believe that the application of these new-generation tools in turn would provide crop-based solutions to hidden hunger worldwide for achieving global nutritional security.

    2015-07-01

    Full Text Available Minor millets comprise a group of cereal species that are genetically diverse and adapted to a range of marginal growing conditions where major cereals such as wheat, rice, and maize are relatively unsuccessful. Millets require few inputs and withstand severe biotic and abiotic stresses. They are also more nutritious than major cereals. Despite these advantages, neglect in several arenas has resulted in a steady decline in the cultivation of minor millets in India over the past few decades. As part of a United Nations global project on underutilized species, we undertook action research intended to stem the decline in cultivation and enhance the conservation and use of minor millets in 753 households spread across 34 villages in four states of India. Our aim was to improve incomes, nutritional status, and empowerment, especially for women. Overall, our holistic approach to mainstreaming species such as finger millet, little millet, foxtail millet, and barnyard millet indicates that these neglected and underutilized species can play a strategic role in improving many dimensions of livelihoods.

    Flaxseed flour was used as a functional ingredient in the production of beef patties. Beef patties were produced with five different formulations; the addition of 3%, 6%, 9%, 12% and 15% flaxseed flour. Control samples were formulated with 10% and 20% fat addition. Raw and cooked beef patties were analyzed for moisture, protein, fat, ash, pH, color parameters and fatty acid profiles. Beef patties were evaluated for cooking loss and sensory properties. Fat and ash content of raw patties increased, while moisture and protein content decreased with increased flaxseed flour. The same trend (except fat content) was also observed after cooking. The addition of flaxseed flour did not affect pH values of raw and cooked beef patties. The addition of flaxseed flour improved the cooking loss but, increased the energy value (as kcal/100g). L and a values of raw beef patties containing flaxseed flour were close to controls with 10% fat. α-linolenic acid content of raw and cooked beef patties increased as the level of flaxseed flour increased. The PUFA/SFA ratio increased from 0.04 in the control with 10% fat to 0.62 in the raw beef patties with 15% flaxseed flour. The n-6/n-3 ratio decreased from 5.76 in the control with 10% fat to 0.36 in the raw beef patties with 15% flaxseed flour. The nutritional status of beef patties was enhanced with minimal composition and sensory changes with 3% or 6% flaxseed flour addition.

    Full Text Available Size-dependent mortality influences the recolonization success of juvenile corals transplanted for reef restoration and assisting juvenile corals attain a refuge size would thus improve post-transplantation survivorship. To explore colony size augmentation strategies, recruits of the scleractinian coral Pocillopora damicornis were fed with live Artemia salina nauplii twice a week for 24 weeks in an ex situ coral nursery. Fed recruits grew significantly faster than unfed ones, with corals in the 3600, 1800, 600 and 0 (control nauplii/L groups exhibiting volumetric growth rates of 10.65 ± 1.46, 4.69 ± 0.9, 3.64 ± 0.55 and 1.18 ± 0.37 mm3/week, respectively. Corals supplied with the highest density of nauplii increased their ecological volume by more than 74 times their initial size, achieving a mean final volume of 248.38 ± 33.44 mm3. The benefits of feeding were apparent even after transplantation to the reef. The corals in the 3600, 1800, 600 and 0 nauplii/L groups grew to final sizes of 4875 ± 260 mm3, 2036 ± 627 mm3, 1066 ± 70 mm3 and 512 ± 116 mm3, respectively. The fed corals had significantly higher survival rates than the unfed ones after transplantation (63%, 59%, 56% and 38% for the 3600, 1800, 600 and 0 nauplii/L treatments respectively. Additionally, cost-effectiveness analysis revealed that the costs per unit volumetric growth were drastically reduced with increasing feed densities. Corals fed with the highest density of nauplii were the most cost-effective (US$0.02/mm3, and were more than 12 times cheaper than the controls. This study demonstrated that nutrition enhancement can augment coral growth and post-transplantation survival, and is a biologically and economically viable option that can be used to supplement existing coral mariculture procedures and enhance reef restoration outcomes.

    Patients with head and neck cancer undergoing surgery have a high occurrence of postoperative complications. The aim of our study was to investigate whether postoperative nutrition of head and neck cancer patients, using an enhanced enteral formula with three different doses of arginine could improve nutritional variables as well as clinical outcome, depending of arginine dose. A population of 84 patients with oral and laryngeal cancer was enrolled. At surgery patients were randomly assigned to three different treatment groups, each one containing at less 28 patients. Group I (28 patients) received an enteral diet supplements with a low physiological dose of arginine (5.7 g per day), group II (28 patients) received an isocaloric, isonitrogenous enteral formula with a medium dose of arginine (12.3 g per day) and group III (28 patients) received an isocaloric, isonitrogenous enteral formula with a high dose of arginine (18.9 g per day). The length of postoperative stay had a trend to be better with high dose of arginine received (31.9 ± 17.2 days in group I vs 27.8 ± 15.2 days in group II vs 24.8 ± 18.3 days in group III: p = 0.034). No differences were detected in postoperative infections complications and diarrhea. Fistula was less frequent in groups II and III than I (10.7% group I vs 3.6% group II vs 3.6% group III: p = 0.033), The length of postoperative stay had a trend to be better with high dose of arginine received (31.9 ± 17.2 days in group I vs 27.8 ± 15.2 days in group II vs 24.8 ± 18.3 days in group III: p = 0.034). Our results suggest that these patients could benefit from a high dose of arginine enhanced enteral formula to decrease length of hospital stay and fistula wound complications.

    Full Text Available Surgery is a stressful and anxiety provoking experience for children. Millions of children undergo surgery every year. The majority of children experience significant preoperative anxiety which intern can affect their recovery. Preoperative anxiety may bring about physical and physiological changes in children, which can be particularly evident in terms of increased heart rate and blood pressure. To identify various strategies used to minimize the preoperative anxiety of children and update their clinical effectiveness among children undergoing surgery, the authors searched PubMed, MEDLINE, CINAHL, ScienceDirect, Google Scholar, Scopus, and Cochrane Library for identifying the relevant studies and retrieved available literature. It is concluded that utilization of the strategies available to reduce the preoperative anxiety of children will be a promising intervention to reduce anxiety, to promote relaxation, satisfaction, and speedy recovery. Many of these techniques are simple, cost-effective and can be easily carried out by nurses. It is essential to use the age appropriate and individualized methods in preparing children for surgery. Further research is required to strengthen the evidence.

    Reports from nutritional epidemiology studies lack reliability if based solely on self-reported dietary consumption estimates. Consumption biomarkers are available for some components of diet. These can be collected in subsets of study cohorts, along with corresponding self-report assessments. Linear regression of (log-transformed) biomarker values on corresponding self-report values and other pertinent study subject characteristics yields calibration equations for dietary consumption, from w...

    Enhanced early-life nutrition (∼130% of required energy and protein) increased testes size and weight (∼20-25%) and reduced age at puberty (∼1 month) in beef and dairy bulls, compared with those fed 70% of dietary requirements. The objective was to determine effects of early-life (2-31 weeks) nutritional modulation on feed costs, predicted number of harvestable sperm and doses of semen, and semen quality. Calves (∼1 week old) were randomly allocated into three groups that were fed 4, 6, or 8 L/day of milk (low [n = 8], medium [n = 9], and high groups [n = 9], respectively) from ages 2 to 8 weeks. Thereafter, they were weaned, transitioned onto barley silage-based diets, to receive ∼70, 100, or 130% of recommended amounts of energy and protein (feed costs were ∼CDN$280 more per bull to feed high versus low diets from 2 to 31 weeks). After 31 weeks, all bulls were fed a medium diet. Semen was collected, by electroejaculation, from 51 to 73 weeks, extended, chilled, and cryopreserved. Bulls fed high nutrition were numerically younger (P = 0.45) at sexual maturity (sperm with ≥30% progressive motility, ≥70% morphologically normal, and ≤20% abnormal heads), first acceptable post-chill sperm motility (>50%; P = 0.66) and first acceptable post-thaw motility (>25% progressive; P = 0.25) than bulls in the low-nutrition group. Semen from three bulls per group was used for in vitro fertilization (total of 1249 bovine oocytes); there were no significant differences among groups in fertilization percentage (mean ± SEM of 68.0 ± 8.7, 77.1 ± 3.5, and 68.7 ± 4.5% for low, medium, and high, respectively) or blastocyst yield (31.5 ± 5.6, 41.4 ± 4.9, and 33.7 ± 4.6%). On the basis of analysis of 2D gels of sperm proteins, 380 spots were identified on the fused master gel, but no spots were differentially expressed across groups. Overall, there were no significant differences in semen quality or sperm function among bulls fed

    In the last 20 years, Public Health Nutrition focused mainly on the qualitative aspects which may influence the onset of chronic diseases, quality of life, physical and mental performance and life expectancy. This applied knowledge organised as part of preventive and health promotion programs led to the development of Community Nutrition. The aim of Community Nutrition actions is to adequate lifestyles related to food consumption patterns in order to improve the quality of life and contribute to health promotion of the population in the community where programs and services are delivered. Key functions to develop in a Community Nutrition Unit consist in the identification and assessment of nutrition problems in the community as well as the design, implementation and evaluation of intervention programs by means of appropriate strategies. These should aim at different populations groups and settings, such as work places, schools, high risk groups or the general public. Nowadays, Community Nutrition work efforts should focus on three main aspects: nutrition education in schools and in the community; food safety and food security and the development and reinforcement of food preparation skills across all age groups. Social catering services, either in schools, the work place or at the community level, need to ensure adequate nutritional supply, provide foods contributing to healthy eating practices as well as to enhance culinary traditions and social learning. Food safety and food security have become a top priority in Public Health. The concepts referes to the availability of food safe and adequate as well as in sufficient amount in order to satisfy nutrition requirements of all individuals in the community. Social changes along new scientific developments will introduce new demands in Community Nutrition work and individual dietary counselling will become a key strategy. In order to face new challenges, community nutrition pactitioners require a high quality

  10. Pre-operative anaemia.

    Science.gov (United States)

    Clevenger, B; Richards, T

    2015-01-01

    Pre-operative anaemia is a relatively common finding, affecting a third of patients undergoing elective surgery. Traditionally associated with chronic disease, management has historically focused on the use of blood transfusion as a solution for anaemia in the peri-operative period. Data from large series now suggest that anaemia is an independent risk associated with poor outcome in both cardiac and non-cardiac surgery. Furthermore, blood transfusion does not appear to ameliorate this risk, and in fact may increase the risk of postoperative complications and hospital length of stay. Consequently, there is a need to identify, diagnose and manage pre-operative anaemia to reduce surgical risk. Discoveries in the pathways of iron metabolism have found that chronic disease can cause a state of functional iron deficiency leading to anaemia. The key iron regulatory protein hepcidin, activated in response to inflammation, inhibits absorption of iron from the gastrointestinal tract and further reduces bioavailability of iron stores for red cell production. Consequently, although iron stores (predominantly ferritin) may be normal, the transport of iron either from the gastrointestinal tract or iron stores to the bone marrow is inhibited, leading to a state of 'functional' iron deficiency and subsequent anaemia. Since absorption from the gastrointestinal tract is blocked, increasing oral iron intake is ineffective, and studies are now looking at the role of intravenous iron to treat anaemia in the surgical setting. In this article, we review the incidence and impact of anaemia on the pre-operative patient. We explain how anaemia may be caused by functional iron deficiency, and how iron deficiency anaemia may be diagnosed and treated.

    Objective: To investigate non-contrast-enhanced Fourier decomposition MRI (FD MRI) for assessment of regional lung perfusion in patients with Non-Small-Cell Lung Cancer (NSCLC) in comparison to dynamic contrast-enhanced MRI (DCE MRI). Methods: Time-resolved non-contrast-enhanced images of the lungs were acquired prospectively in 15 patients using a 2D balanced steady-state free precession (b-SSFP) sequence. After non-rigid registration of the native image data, perfusion-weighted images were calculated by separating periodic changes of lung proton density at the cardiac frequency using FD. DCE MRI subtraction datasets were acquired as standard of reference. Both datasets were analyzed visually for perfusion defects. Then segmentation analyses were performed to describe perfusion of pulmonary lobes semi-quantitatively as percentages of total lung perfusion. Overall FD MRI perfusion signal was compared to velocity-encoded flow measurements in the pulmonary trunk as an additional fully quantitative reference. Results: Image quality ratings of FD MRI were significantly inferior to those of DCE MRI (P < 0.0001). Sensitivity, specificity, and accuracy of FD MRI for visual detection of perfusion defects were 84%, 92%, and 91%. Semi-quantitative evaluation of lobar perfusion provided high agreement between FD MRI and DCE MRI for both entire lungs and upper lobes, but less agreement in the lower parts of both lungs. FD perfusion signal showed high linear correlation with pulmonary arterial blood flow. Conclusion: FD MRI is a promising technique that allows for assessing regional lung perfusion in NSCLC patients without contrast media or ionizing radiation. However, for being applied in clinical routine, image quality and robustness of the technique need to be further improved.

    Full Text Available Infant malnutrition in sub-Saharan Africa is a public health priority and a challenge in high HIV prevalence areas. The Drug Resources Enhancement Against AIDS and Malnutrition program, with multiple medical centers in Sub-Saharan Africa, developed an innovative intervention for the surveillance and control of malnutrition. In a pilot initiative, 36 HIV-exposed children were evaluated at baseline upon presentation for malnutrition and at six months post- treatment. Parameters included HIV-free survival, nutritional status and change in diet. Food diary data was entered and processed using the Nutrisurvey (WHO software. At 6 months post-intervention, a significant improvement in anthropometric parameters was noted. Slowing of linear growth was observed in patients with malaria with a mean gain in centimetres of 4.4 ± 1.7 as compared to 5.6 ± 1.7 in children with no malaria, p < 0.048 (CL 95%: −2.32, −0.01. Dietary diversity scores increased from 5.3 ± 1.9 to 6.5 ± 1.3, p < 0.01 at 6 months. A significant increase (+25%, p < 0.02 in the number of children eating fish meals was noted. Our pilot data describes positive outcomes from a rehabilitative nutritional approach based on use of local foods, peer education, anthropometric and clinical monitoring in areas of high food insecurity. The relationship between malaria and linear growth retardation requires further investigation.

    Consumption of legumes is associated with a number of physiological and health benefits. Legume proteins complement very well those of cereals and are often used to produce gluten-free products. However, legume seeds often contain antinutritional compounds, such as phytate, galactooligosaccharides, phenolic compounds, lectins, enzyme inhibitors, whose presence could affect their nutritional value. Screening natural and induced biodiversity for useful traits, followed by breeding, is a way to remove undesirable components. We used the common bean cv. Lady Joy and the lpa1 mutant line, having different seed composition for absence/presence of lectins,α-amylase inhibitor, (α-AI) and phytic acid, to verify the advantage of their use to make biscuits with improved nutritional properties. We showed that use of unprocessed flour from normal beans (Taylor's Horticulture and Billò) must be avoided, since lectin activity is still present after baking, and demonstrated the advantage of using the cv. Lady Joy, lacking active lectins and having active α-AI. To assess the contribution of bean flour to biscuit quality traits, different formulations of composite flours (B12, B14, B22, B24, B29) were used in combinations with wheat (B14), maize (gluten-free B22 and B29), or with both (B12 and B24). These biscuits were nutritionally better than the control, having a better amino acid score, higher fiber amount, lower predicted glycemic index (pGI) and starch content. Replacement of cv. Lady Joy bean flour with that of lpa1, having a 90% reduction of phytic acid and devoid of α-AI, contributed to about a 50% reduction of phytic acid content. We also showed that baking did not fully inactivate α-AI, further contributing to lowering the pGI of the biscuits. Finally, data from a blind taste test using consumers indicated that the B14 biscuit was accepted by consumers and comparable in terms of liking to the control biscuit, although the acceptability of these products decreased

    Anxiety is common in surgical patients, with an incidence of 60% to 92%. There is little information on the incidence and severity of preoperative anxiety in patients scheduled for neurosurgery. The aim of this study was to measure the level of preoperative anxiety in neurosurgical patients and to assess any influencing factors. After the Institutional Review Board approval and informed written consent, 100 patients booked for neurosurgery were interviewed preoperatively. Each patient was asked to grade their preoperative anxiety level on a verbal analog scale, Amsterdam Preoperative Anxiety and Information Scale, and a set of specific anxiety-related questions. The anxiety scores and the responses to the questions were compared between the sex, age, weight, diagnosis, and history of previous surgery. The mean age (+/-SD) was 50+/-13 years. The preoperative diagnosis was tumor (n=64), aneurysm (n=14), and other (n=22). Overall verbal analog scale was 5.2+/-2.7; the score was higher for female (5.8+/-2.8) than male patients (4.6+/-2.5) (PAmsterdam Preoperative Anxiety and Information Scale anxiety and knowledge scores were greater for surgery than for anesthesia. Questionnaire results showed that the most common anxieties were waiting for surgery, physical/mental harm, and results of the operation. In conclusion, our study showed that neurosurgical patients have high levels of anxiety, with a higher incidence in females. There was a moderately high need for information, particularly in patients with a high level of preoperative anxiety.

    Study of the nutrition pathway for lumbar intervertebral disk cartilage of normal goats. Four lumbar intervertebral disks from each of eight 24-month-old goats (32 disks) were studied. After the goats had been anesthetized, signal intensity changes in the regions of interest (ROI) were observed by dynamic contrast enhanced magnetic resonance scanning. Before and after enhancement at the time points of 0, 5, 10, and 30 mins, and 1.0, 1.5, 2.0, 2.5, 3.0, and 3.5 hs, the ROI signal intensity was measured, and the time-signal intensity curve and peak times analyzed. Signal intensity in the vertebral bodies reached a peak at 0 min and decreased quickly thereafter. Signal intensity in the cartilage endplate zones reached the first peak at 30 mins and then went down slightly before increasing to a second peak at 2 hs. Signal intensity in the nuclei pulposus was negative within 5 mins, increased slowly to a peak at 2 hs, and declined thereafter. Nutrient metabolism of the lumbar intervertebral disks of normal goats occurs mainly through the cartilage end-plate pathway. © 2011 Tianjin Hospital and Blackwell Publishing Asia Pty Ltd.

    This study on flavor enhancers aims to: 1) compare food intake of older persons, 2) determine changes in body weight, blood pressure and serum sodium and 3) determine tolerance/intolerance to the flavor enhancers. The project is a cross-over, double blind study design. A nursing home for the aged, Golden Acres Institution located in Quezon City, Philippines. Sixty eligible subjects (31 males and 29 females), aged 60 years and over. Subjects were initially given: pouch A (0.5gram monosodium glutamate) or pouch B (0.5gram iodized salt) for lunch and supper for 2 months. The intervention was switched after one week wash period. Before the start and during intervention, 24 hour food intake of subjects was recorded and anthropometric and clinical data were measured. Tolerance/intolerance to the flavor enhancer and data on the quality of life were evaluated using a pre-tested structured questionnaire. Paired t-test was used to determine significant changes among each period of dietary intervention between different groups. Energy intake and almost all nutrients increased for males and females for both interventions. Body weight and body mass index increased significantly for both gender with MSG usage but not with iodized salt. The diastolic blood pressure of all subjects was normal while the systolic blood pressure remained at pre-hypertension level before and after both interventions. The sodium serum was within normal levels for both groups for both interventions. It was also observed that systolic blood pressure increased in both groups while sodium levels did not. It was further observed that both MSG and iodized salt interventions were well tolerated by majority of the participants. The use of flavor enhancers have increased food intake and were well- tolerated among older persons. No difference in blood pressure and sodium serum was noted in both MSG and iodized salt intake. People with less appetite, especially among older persons can use flavor enhancers to

    Hedgehog signaling is a pivotal developmental pathway that comprises hedgehog, PTCH1, SMO, and GLI proteins. Mutations in PTCH1 are responsible for Gorlin syndrome, which is characterized by developmental defects and tumorigenicity. Although the hedgehog pathway has been investigated extensively in Drosophila and mice, its functional roles have not yet been determined in human cells. In order to elucidate the mechanism by which transduction of the hedgehog signal is regulated in human tissues, we employed human fibroblasts derived from three Gorlin syndrome patients and normal controls. We investigated GLI1 transcription, downstream of hedgehog signaling, to assess native signal transduction, and then treated fibroblasts with a recombinant human hedgehog protein with or without serum deprivation. We also examined the transcriptional levels of hedgehog-related genes under these conditions. The expression of GLI1 mRNA was significantly higher in Gorlin syndrome-derived fibroblasts than in control cells. Hedgehog stimulation and nutritional deprivation synergistically enhanced GLI1 transcription levels, and this was blocked more efficiently by vismodegib, a SMO inhibitor, than by the natural compound, cyclopamine. Messenger RNA profiling revealed the increased expression of Wnt signaling and morphogenetic molecules in these fibroblasts. These results indicated that the hedgehog stimulation and nutritional deprivation synergistically activated the hedgehog signaling pathway in Gorlin syndrome fibroblasts, and this was associated with increments in the transcription levels of hedgehog-related genes such as those involved in Wnt signaling. These fibroblasts may become a significant tool for predicting the efficacies of hedgehog molecular-targeted therapies such as vismodegib.

    Objective:To investigate the effect of NRS2002 in screening preoperative nutritional risk in patients with pancreatic cancer. Methods: NRS2002 was used to screen nutritional risk for 74 pancreatic cancer patients before surgery. The serum albumin and prealbumin were used as the standards to evaluate its sensitivity and specificity. The operation complications and the average hospitalization days of the patients with malnutrition were observed and compared with those of the patients without nutritional risk. Results: The sensitivity and specificity of NRS2002 was 58. 3% and 86% respectively when prealbumin was taken as the standard and it was 66. 7% and 93. 6% respectively when serum albumin was taken as the standard. The overall incidence of postoperative complications were higher in the patients whose NRS scores were more than 3 points than those of whose NRS scores less than 3 points. The incidence of abdominal infection complication increased significantly, and the average hospitalization days were relatively longer in the patients whose NRS score≥3 points ( P < 0. 05 ). Conclusion:NRS2002 was a convenient tool for screening preoperative nutritional risk in patients with pancreatic cancer owing to its higher sensitivity and specificity.%目的:探讨营养风险筛查(NRS2002)在胰腺癌患者术前营养风险筛查中的应用效果.方法:应用NRS2002对74例胰腺癌手术患者进行营养风险筛查,并以血清白蛋白和前白蛋白作为标准,评价其敏感性和特异性.观察NRS2002筛查出营养不良患者的手术并发症发生率及平均住院天数,与无营养不良风险的患者进行比较.结果:以前白蛋白为标准,NRS2002的敏感性为58.3%,特异性为86.0%;以白蛋白为标准,NRS2002的敏感性为66.7%,特异性为93.6%;NRS评分≥3分术后并发症的总发生率高于NRS评分<3分者,其中腹腔感染并发症发生率显著增高,并且平均住院时间较NRS评分<3 分者长(P<0.05).结论:应用NRS2002对

    Ascorbate (or vitamin C) is an essential human micronutrient predominantly obtained from plants. In addition to preventing scurvy, it is now known to have broader roles in human health, for example as a cofactor for enzymes involved in epigenetic programming and as regulator of cellular iron uptake. Furthermore, ascorbate is the major antioxidant in plants and underpins many environmentally induced abiotic stress responses. Biotechnological approaches to enhance the ascorbate content of crops therefore have potential to improve both human health and abiotic stress tolerance of crops. Identifying the genetic basis of ascorbate variation between plant varieties and discovering how some 'super fruits' accumulate extremely high levels of ascorbate should reveal new ways to more effectively manipulate the production of ascorbate in crops.

    The purpose of this article is to prospectively and directly compare the capabilities of non-contrast-enhanced MR angiography (MRA), 4D contrast-enhanced MRA, and contrast-enhanced MDCT for assessing pulmonary vasculature in patients with non-small cell lung cancer (NSCLC) before surgical treatment. A total of 77 consecutive patients (41 men and 36 women; mean age, 71 years) with pathologically proven and clinically assessed stage I NSCLC underwent thin-section contrast-enhanced MDCT, non-contrast-enhanced and contrast-enhanced MRA, and surgical treatment. The capability for anomaly assessment of the three methods was independently evaluated by two reviewers using a 5-point visual scoring system, and final assessment for each patient was made by consensus of the two readers. Interobserver agreement for pulmonary arterial and venous assessment was evaluated with the kappa statistic. Then, sensitivity, specificity, and accuracy for the detection of anomalies were directly compared among the three methods by use of the McNemar test. Interobserver agreement for pulmonary artery and vein assessment was substantial or almost perfect (κ=0.72-0.86). For pulmonary arterial and venous variation assessment, there were no significant differences in sensitivity, specificity, and accuracy among non-contrast-enhanced MRA (pulmonary arteries: sensitivity, 77.1%; specificity, 97.4%; accuracy, 87.7%; pulmonary veins: sensitivity, 50%; specificity, 98.5%; accuracy, 93.2%), 4D contrast-enhanced MRA (pulmonary arteries: sensitivity, 77.1%; specificity, 97.4%; accuracy, 87.7%; pulmonary veins: sensitivity, 62.5%; specificity, 100.0%; accuracy, 95.9%), and thin-section contrast-enhanced MDCT (pulmonary arteries: sensitivity, 91.4%; specificity, 89.5%; accuracy, 90.4%; pulmonary veins: sensitivity, 50%; specificity, 100.0%; accuracy, 95.9%) (p>0.05). Pulmonary vascular assessment of patients with NSCLC before surgical resection by non-contrast-enhanced MRA can be considered equivalent to

    Forty-six strains of sourdough lactic acid bacteria were screened for proteolytic activity and acidification rate in gluten-free (GF) flours. The sourdough cultures consisted of Lactobacillus sanfranciscensis LS40 and LS41 and Lactobacillus plantarum CF1 and were selected and used for the manufacture of GF bread. Fermentation occurred in two steps: (i) long-time fermentation (16 h) and (ii) fast fermentation (1.5 h) using the previous fermented sourdough as inoculum (ca. 43%, wt/wt) with Saccharomyces cerevisiae (baker's yeast). GF bread started with baker's yeast alone was used as the control. Gluten was added to ingredients before fermentation to simulate contamination. Initial gluten concentration of 400 ppm was degraded to below 20 ppm only in the sourdough GF bread. Before baking, sourdough GF bread showed phytase activity ca. sixfold higher than that of GF bread started with baker's yeast alone. Atomic absorption spectrophotometric analysis revealed that the higher phytase activity resulted in an increased availability of free Ca2+, Zn2+, and Mg2+. The concentration of free amino acids also was the highest in sourdough GF bread. Sourdough GF bread had a higher specific volume and was less firm than GF bread started with baker's yeast alone. This study highlighted the use of selected sourdough cultures to eliminate risks of contamination by gluten and to enhance the nutritional properties of GF bread.

    The nutritional quality of green leafy vegetables can be enhanced by application of plant beneficial micro-organisms. The present study was aimed to increase the food values of lettuce leaves by bacterial treatment. We isolated bacterial strain KE2 from Kimchi food and identified as Bacillus methylotrophicus by phylogenetic analysis. The beneficial effect of B. methylotrophicus KE2 on plants was confirmed by increasing the percentage of seed germination of Lactuca sativa L., Cucumis melo L., Glycine max L. and Brassica juncea L. It might be the secretion of array of gibberellins (GA1, GA3, GA7, GA8, GA9, GA12, GA19, GA20, GA24, GA34 and GA53) and indole-acetic acid from B. methylotrophicus KE2. The mechanism of plant growth promotion via their secreted metabolites was confirmed by a significant increase of GA deficient mutant rice plant growth. Moreover, the bacterial association was favor to enhance shoot length, shoot fresh weight and leaf width of lettuce. The higher concentration of protein, amino acids (Asp, Thr, Ser, Glu, Gly, Ala, Leu, Tyr and His), gama-aminobutric acid and fructose was found in bacterial culture (KE2) applied plants. The macro and micro minerals such as K, Mg, Na, P, Fe, Zn and N were also detected as significantly higher quantities in bacteria treated plants than untreated control plants. In addition, the carotenoids and chlorophyll a were also increased in lettuce at bacterial inoculation. The results of this study suggest that B. methylotrophicus KE2 application to soil helps to increase the plant growth and food values of lettuce. Copyright © 2016 Elsevier Masson SAS.

    We have shown that a controlled-flow vacuum-free bottle system (CFVFB) vs. a standard bottle (SB) facilitates overall transfer and rate of milk transfer, and shortens oral feeding duration in very-low-birth-weight (VLBW) infants. We aimed to understand the basis by which this occurs. Thirty infants (19 males; 27 +/- 1 weeks gestation) were randomized to a CFVFB or SB. Outcomes monitored at 1-2 and 6-8 oral feedings/day when infants were around 34 and 36 weeks postmenstrual age, respectively, included: overall transfer (% volume taken/volume prescribed), rate of milk transfer (ml/min), sucking stage, frequency of suction (#S/s) and expression (#E/s), suction amplitude (mmHg), and sucking burst duration (s). At both periods we confirmed that infants using a CFVFB vs. SB demonstrated greater overall transfer and rate of milk transfer, along with more mature sucking stages. Suction and expression frequencies were decreased with CFVFB vs. SB at 1-2 oral feeding/day; only that of suction was reduced at 6-8 oral feedings/day. No group differences in suction amplitude and burst duration were observed. We speculate that oral feeding performance improves without significant change in sucking effort with a CFVFB vs. SB. In addition, we have shown that VLBW infants can tolerate faster milk flow than currently presumed. Finally, the use of a CFVFB may reduce energy expenditure as it enhances feeding performance without increasing sucking effort.

    Full Text Available Isoflavones are large group of secondary metabolites produced in legumes such as soybeans. They have essential biological functions as nutraceutical and health functions for human. They are involved in plant resistance to biotic and abiotic stresses, symbiotic relationship with nitrogen-fixing organisms and plant competition (allelopathy. In this report, isoflavonoids were expressed in wheat (Triticum aestivum via introducing the key enzymes Isoflavone Synthase (IFS. Transgenic callli induced from wheat immature embryos were propagated and prepared for bombardment. Five gene constructs were prepared; the binary vector (plasmid pAHC25, 35S-CRC, 35S-IFS, Oleocin-IFS, Oleocin-IFS-CHI and were used for wheat calli transformation. Putative transgenic calli were used to regenerate transgenic wheat plants. Evaluation of recovered transgenic plants was carried out using PCR, southern bloting of PCR products and IFS-specific probe and HPLC analysis of transgenic plant tissue extracts. Genistein and naranigenin were detected in transgenic plants carrying IFS gene, indicating that the introduced IFS was able to use the endogenous substrate from wheat. IFS showed activity under 35S promoter as well as oleocin promoter. The activity of oleocin promoter in monocots provides a good tool to use plant promoters to drive plant gene expression in plants. This also represents promoter compatibility that the cis acting elements of the oleocin promoter represent binding targets for trans acting elements of wheat. Engineering the isoflavone pathway in wheat would lead to enhancement of nutraceutical value of wheat grains and improvement of wheat resistance to diseases.

    Raw seed kernels of local mango varieties (Magnifera indica L.) were analyzed for composition, levels of trypsin inhibitors, tannins, cyanogenetic glucosides, in vitro protein digestibility and apparent metabolizable energy (AMEN) as being effected by boiling, autoclaving as well as irradiation at 5, 10, 15, and 20 kGy. The air-dry mango seed kernels (MSK) contained CP 70 g kg-1, EE 128 g kg-1, and tannins 67 g kg-1. Compared with raw kernels the contents of trypsin inhibitory activity (30 TIU g-1) and cyanogenetic glucosides, measured as hydrocyanic acid (71 mg kg-1), were lowered by boiling, autoclaving and radiation treatments. Tannin content (67.2 g kg-1 in raw kernels) was decreased only by boiling or autoclaving, but irradiation did not introduce any effect. The low in vitro protein digestibility and AMEN values of raw MSK were enhanced by processing. The improvements were paralleled to reductions in trypsin inhibitory activity, cyanogenetic glucosides and tannin contents. Greater improvements were noticed with boiling and autoclaving than with irradiation alone. Autoclaving for 30 min plus irradiation treatment up to 20 kGy increased the in vitro protein digestibility and AMEN by 139% and 72%, respectively. These results indicate that tannins, trypsin inhibitors and cyanogenetic glucosides are responsible for the poor nutritive value of MSK. The effects of feeding 200 g kg-1 raw or processed MSK on the performance of broiler chicks were examined. The inclusion of raw kernel affected body weight gain and feed consumption, while weight gain of birds fed the autoclaved (30 min) plus irradiated (20 kGy) kernels was significantly more improved than by the other treatments. However, feed conversion ratio was not significantly different between groups fed the processed MSK. The results showed that the combination of autoclaving for 30 min plus irradiation up to 20 kGy upgraded the nutritive value more than the other tested treatments and that this method is most

    To compare diagnostic performance in the detection of colorectal liver metastases between 64-detector-row contrast-enhanced CT (CE-CT) alone and the combination of CE-CT and gadoxetic acid-enhanced MRI (EOB-MRI) at 3.0T, and to assess whether EOB-MRI in addition to CE-CT results in a change to initially planned operative strategy. A total of 39 patients (27 men, mean age 65 years) with 85 histopathologically confirmed liver metastases were included. At EOB-MRI, unenhanced (T1- and T2-weighted), dynamic, and hepatocyte-phase images were obtained. At CE-CT, four-phase dynamic contrast-enhanced images were obtained. One on-site reader and three off-site readers independently reviewed both CE-CT alone and the combination of CE-CT and EOB-MRI. Sensitivity, positive predictive value, and alternative free-response receiver operating characteristic (AFROC) method were calculated. Differences in therapeutic strategy before and after the EOB-MRI examination were also evaluated. Sensitivity and area under the AFROC curve with the combination of CE-CT and EOB-MRI were significantly superior to those with CE-CT alone. Changes in surgical therapy were documented in 13 of 39 patients. The combination of CE-CT and EOB-MRI may provide better diagnostic performance than CE-CT alone for the detection of colorectal liver metastases, and EOB-MRI in addition to CE-CT resulted in changes to the planned operative strategy in one-third of the patients.

    2008-01-01

    Detailed preoperative staging using high resolution magnetic resonance imaging (MRI) enables the selection of patients that require preoperative therapy for tumour regression. This information can be used to instigate neoadjuvant therapy in those patients with poor prognostic features prior to disturbing the tumour bed and potentially disseminating disease. The design of trials incorporating MR assessment of prognostic factors prior to therapy has been found to be of value in assessing treatment modalities and outcomes that are targeted to these preoperative prognostic subgroups and in providing a quantifiable assessment of the efficacy of particular chemoradiation treatment protocols by comparing pre-treatment MR staging with post therapy histology assessment. At present, we are focused on achieving clear surgical margins of excision (CRM) to avoid local recurrence. We recommend that all patients with rectal cancer should undergo pre-operative MRI staging. Of these, about half will have good prognosis features (T1-T3b, N0, EMVI negative, CRM clear) and may safely undergo primary total mesorectal excision. Of the remainder, those with threatened or involved margins will certainly benefit from pre-operative chemoradiotherapy with the aim of downstaging to permit safe surgical excision. In the future, our ability to recognise features predicting distant failure, such as extramural vascular invasion (EMVI) may be used to stratify patients for neo-adjuvant systemic chemotherapy in an effort to prevent distant relapse. The optimal pre-operative treatment regimes for these patients (radiotherapy alone, systemic chemotherapy alone or combination chemo-radiotherapy) is the subject of current and future trials.

    Preoperative anxiety is a common and poorly evaluated condition in patients who will undergo an anesthetic and surgical intervention. The objective of this study was to determine the prevalence of anxiety in a group of patients undergoing elective surgery, as assessed by the Amsterdam Anxiety Preoperative and Information (AAPI) scale. We studied 135 patients scheduled for elective surgery applying the AAPI scale 24 h before the surgical procedure to evaluate the presence of anxiety and patient characteristics. A descriptive analysis with mean +/- standard deviation for categorical variables was done. For intragroup differences, chi(2) test was used. Pearson correlation for the association between anxiety and postoperative complications was carried out. A value of p =0.05 was considered significant. One hundred six patients were surgically treated, 88% were female (average age 44 +/- 12 years). Some degree of preoperative anxiety was present in 72 patients (76%; p = 0.001) with a grade point average on the AAPI scale equal to 17 +/- 7 points, of which 95 (70%, OR = 5.08; p = 0.002) were females. Results of this study suggest the presence of high levels of preoperative anxiety in patients scheduled for elective surgery. The origin of the anxiety appears to be related to many factors that can be evaluated in pre-anesthetic consultation. Further study is needed to prevent the presence of this disorder.

    Residual biogas slurries (BGS) of detoxified mahua cake and cow dung were used as supplements to enhance the yield and nutritional quality of Lentinus sajor-caju on wheat straw (WS). Supplementation with 20% BGS gave a maximum yield of 1155 gkg-1 fruit bodies, furnishing an increase of 95.1% over WS control. Significant increase (p ≤ 0.05) in protein content (29.6-38.9%), sugars (29.1-32.3%) and minerals (N, P, K, Fe, Zn) was observed in the fruit bodies. Principle component analysis (PCA) was performed to see the pattern of correlation within a set of observed variables and how these different variables varied in different treatments. PC1 and PC2 represented 90% of total variation in the observed variables. Moisture (%), lignin (%), celluloses (%), and C/N ratio were closely correlated in comparison to Fe, N, and saponins. PCA of amino acids revealed that, PC1 and PC2 represented 74% of total variation in the data set. HPLC confirmed the absence of any saponin residues (characteristic toxins of mahua cake) in fruit bodies and mushroom spent. FTIR studies showed significant degradation of celluloses (22.2-32.4%), hemicelluloses (14.1-23.1%) and lignin (27.4-39.23%) in the spent, along with an increase in nutrition content. The study provided a simple, cost effective approach to improve the yield and nutritional quality of L. sajor-caju by resourceful utilization of BGS.

    Anesthesiology societies have issued various guidelines on preoperative fasting since 1990, not only to decrease the incidence of lung aspiration and anesthetic morbidity, but also to increase patient comfort prior to anesthesia. Some of these societies have been updating their guidelines, as such that, since 2010, we now have 2 evidence-based preoperative fasting guidelines available. In this article, an attempt is made to review these updated guidelines, as well as the current instructions for more controversial patients such as infants, the obese, and a particular type of ophthalmic surgery.

    Objective:To investigate the effect of enteral nutrition support one week before surgery and postoperative periods on the postoperative immune function and nutritional status in old patients with gastric cancer. Methods:A retrospective analysis was con-ducted on 77 stomach cancer patients who were admitted and received surgical treatment in our hospital. Among the patients, 38 re-ceived enteral nutrition support one week before surgery and early period of postoperation, and were labeled as the experimental group. The remaining 39 patients did not receive enteral nutrition support one week before surgery and early period of postoperation, and were named as the control group. The levels of prealbumin, albumin, transferrin, CD4+T (%), CD8+T (%), and CD4+/CD8+cells were also an-alyzed before surgery and 1 d and 8 d after surgery. Results:No statistical differences in the gender, age, site of tumor, TNM staging, and differentiated degree were found between the two groups. All operations were successful and the patients recovered well after sur-gery. In the nutritional status, the levels of prealbumin, albumin, and transferrin in the patients of the two groups had no significant dif-ference (P>0.05). On the first day after the surgery, the levels of prealbumin, albumin, and transferrin were significantly low in both groups;the control group had lower levels than the experimental group (P0.05). On the first day after surgery, the levels of CD4+T (%), CD8+T (%), and CD4+T/CD8+T cells were significantly low in both groups;the control group had lower levels than the experimental group (P<0.05). Conclusion:Elderly patients with gastric cancer who receive appropriate enteral nutrition support one week before sur-gery would have better immune function and nutritional status after surgery than those who did not, and the recovery of old patients im-proved.%目的:探讨术前1周及术后早期应用肠内营养制剂对老年胃癌患者术后免疫功能及营养状

    The usefulness of neurosurgical navigation with current visualizations is seriously compromised by brain shift, which inevitably occurs during the course of the operation, significantly degrading the precise alignment between the pre-operative MR data and the intra-operative shape of the brain. Our objectives were (i) to evaluate the feasibility of non-rigid registration that compensates for the brain deformations within the time constraints imposed by neurosurgery, and (ii) to create augmented reality visualizations of critical structural and functional brain regions during neurosurgery using pre-operatively acquired fMRI and DT-MRI. Eleven consecutive patients with supratentorial gliomas were included in our study. All underwent surgery at our intra-operative MR imaging-guided therapy facility and have tumors in eloquent brain areas (e.g. precentral gyrus and cortico-spinal tract). Functional MRI and DT-MRI, together with MPRAGE and T2w structural MRI were acquired at 3 T prior to surgery. SPGR and T2w images were acquired with a 0.5 T magnet during each procedure. Quantitative assessment of the alignment accuracy was carried out and compared with current state-of-the-art systems based only on rigid registration. Alignment between pre-operative and intra-operative datasets was successfully carried out during surgery for all patients. Overall, the mean residual displacement remaining after non-rigid registration was 1.82 mm. There is a statistically significant improvement in alignment accuracy utilizing our non-rigid registration in comparison to the currently used technology (paugmented reality visualization to aid the surgeon.

    A retrospective chart review analyzed the effect of customized nutrition on the incidence of pregnancy-induced hypertension (PIH), gestational diabetes (GDM), and small- and large-for-gestational-age (SGA, LGA) neonates, examining consecutive deliveries between January 1, 2011, and Decem ber 31, 2012, at a low-risk community hospital. The population was divided into 3 groups: (1) study group (SG), (2) private practice (PP), and (3) community healthcare clinic (CHCC). All groups received standard perinatal management, but additionally the study group was analyzed for serum zinc, carnitine, total 25-hydroxy cholecalciferol (25 OH-D), methylene tetrahydrofolate reductase, and catechol-O-methyl transferase polymorphisms in the first trimester prior to intervention, with subsequent second trimester and postpartum assessment of zinc, carnitine, and 25 OH-D after intervention. Intervention consisted of trimesterby-trimester nutrition and lifestyle education, supplementation of L-methyl folate, magnesium, essential fatty acids, and probiotics for all SG patients, with targeted supplementation of zinc, carnitine, and 25 OH-D. Because of small case occurrence rates of individual conditions in the study group, unreportable reductions were found, except GDM (SG vs CHCC, P value .046 with 95.38% confidence interval [CI]), and PIH (SG vs PP, P value .0505 with 94.95% CIl). The aggregated occurrence rate of the four conditions, however, was significantly lower in the study population than in either comparison population (PP P value .0154 with 98.46% CI, and CHCC P value .0265 with 97.35% CI). Customized nutritional intervention appears to have significantly reduced adverse perinatal outcomes. Prospective study within larger, at-risk populations is needed to determine whether customized nutrition improves conditions individually. PMID:25568832

  12. Do psychological interventions reduce preoperative anxiety?

    Science.gov (United States)

    Renouf, Tessa; Leary, Alison; Wiseman, Theresa

    The systematic review investigates whether, during preoperative assessments, nurse-delivered psychological interventions reduce anxiety levels preoperatively for patients undergoing elective surgery. Seventeen studies met the inclusion criteria for data extraction and in-depth critiquing. Of these, two were discarded due to lack of validity, while the remaining studies were organised thematically in a narrative synthesis, generating two principal results: patients' preoperative anxieties were lowered by nurse-delivered general preoperative psychological interventions; and patients valued individualised preoperative interventions delivered by nurses. However, the single oncology study in the review showed an elevation in preoperative anxiety, regardless of intervention, and highlights the need for more research in this under-reviewed area. In the meantime, the authors believe that service improvements should be implemented to ensure that, where possible, psychological preoperative interventions are individualised.

    1998-04-01

    Between 1992 and 1996, 31 cases (8 men and 23 women) with primary hyperparathyroidism (PHPT) were treated in our department. In this study, we compared which of the preoperative localization methods was most useful in the detection of PHPT. The sensitivity for detection of abnormal parathyroid glands was 88.6% on ultrasonography (US), 76.9% on magnetic resonance imaging (MRI), 74.3% on Tl-Tc subtraction scintigraphy and 68.8% on computed tomography. We concluded that US should be performed first, with MRI as a supplementary method, for the detection of abnormal parathyroid glands and the evaluation of invasion within the body. (author)

On the basis of this work, it is possible to conclude that the continuing obsession with the body may lead the person to go on diets and other drastic methods to control weight, such as surgical procedures. In this respect, nutritional care is far more than merely recommending a standard diet or giving information, as it represents providing an effective model for nutritional reeducation, prioritizing improvement in the style and quality of life. This article provides data about enhancing esthetics and beauty by means of appropriate nutrition.

    The relationship between preoperative malnutrition and morbi-mortality has been documented for years. Despite the existence of tools that allow its detection, and therefore treat this entity, their introduction into clinical practice is not wide-spread. Both perioperative insulin resistance and hyperglycemia are associated with increased perioperative morbidity and length of hospital stay. The intake of carbohydrate-rich drinks 2-4h prior to surgery reduces insulin resistance. In the immediate postoperative period, the enteral route is safe and well tolerated and its early use reduces hospital stay and postoperative complications compared with parenteral nutritional support. Inmunonutrition has been proven effective to decrease postoperative complications and hospital stay. In view of these data we opted for the adoption of these measures replacing bowel rest and the indiscriminate use of postoperative parenteral nutrition.

    2012-02-01

    The aim of preoperative fasting is to prevent regurgitation and pulmonary aspiration while limiting potential problems of thirst, dehydration and hypoglycaemia. The American Society of Anaesthesiologists (ASA) has suggested guidelines for preoperative fasting for children undergoing elective surgery. We did a postal survey to determine the current practice regarding these guidelines amongst all specialist registrars in anaesthesia in Ireland. A questionnaire was sent to all specialist registrars in anaesthesia (90 in total), 60 (67%) were returned and analysed. The question asked was how long children should be kept fasting before elective surgery. The results of our survey suggest that most of the respondents are following the ASA guidelines for clear fluids and solids however there were differing opinion regarding the duration of fasting for formula milk and breast milk. In conclusion, we would recommend greater awareness and collaboration between anaesthetists, nurses and surgeons to ensure that fasting instructions are consistent with the ASA guidelines and that patient and their parents understand these directives as well.

    This study examined the effects of oral administration of an enzymatic protein hydrolysate from green microalga Chlorella vulgaris (Cv-PH) on the nutritional recovery of malnourished Balb/c mice after a 3-day fasting period. Mice were refed with commercial diet supplemented or not supplemented with Cv-PH (500 mg/kg) for 8 days. Regardless of the diet used during refeeding, animal body weights and serum protein concentrations did not differ between groups. Mice given Cv-PH had a significant increase in hemoglobin concentrations. Most serum amino acid levels were similar in the control and Cv-PH animals. Starved mice refed with Cv-PH showed normal liver functions, as judged by liver weight, protein concentration, and the enzymatic activities of cholinesterase and arginase. Cv-PH increased DNA, protein content, and gut-mucosal weight. In addition, brush-border oligosaccharidase activities were also higher in the Cv-PH group. These findings suggest that Chlorella protein hydrolysate can be used to develop specific formulations suitable for pharmacologic nutrition.

    Personal Digital Assistant (PDA) and wireless communication are currently available in clinical settings. We developed wireless PDA software that assists anesthesiologists in pre-operative patient assessment. The device communicates with the hospital information system through a wireless LAN and is equipped with pre-programmed data entry templates for pre-operative assessment. As a preliminary test of the device, we randomly assigned residents in preoperative assessment to an intervention and a control arm and compared the results.

    Sharon W Kwan

    Full Text Available The purpose of this study was to evaluate the diagnostic capability of imaging modalities used for preoperative mesenteric-left portal bypass ("Rex shunt" planning. Twenty patients with extrahepatic portal vein thrombosis underwent 57 preoperative planning abdominal imaging studies. Two readers retrospectively reviewed these studies for an ability to confidently determine left portal vein (PV patency, superior mesenteric vein (SMV patency, and intrahepatic left and right PV contiguity. In this study, computed tomographic arterial portography allowed for confident characterization of left PV patency, SMV patency and left and right PV continuity in 100% of the examinations. Single phase contrast-enhanced CT, multi-phase contrast-enhanced CT, multiphase contrast-enhanced MRI, and transarterial portography answered all key diagnostic questions in 33%, 30%, 0% and 8% of the examinations, respectively. In conclusion, of the variety of imaging modalities that have been employed for Rex shunt preoperative planning, computed tomographic arterial portography most reliably allows for assessment of left PV patency, SMV patency, and left and right PV contiguity in a single study.

    Khanna, Lauren G; Gress, Frank G

    2015-02-01

    The preoperative evaluation of oesophageal adenocarcinoma involves endoscopic ultrasound (EUS), computed tomography (CT), and positron emission tomography (PET). With routine Barrett's oesophagus surveillance, superficial cancers are often identified. EUS, CT and PET have a limited role in the staging of superficial tumours. Standard EUS has limited accuracy, but high frequency ultrasound miniprobes are valuable for assessing tumour stage in superficial tumours. However, the best method for determining depth of invasion, and thereby stage of disease, is endoscopic mucosal resection. In contrast, in advanced oesophageal cancers, a multi-modality approach is crucial. Accurate tumour staging is very important since the treatment of advanced cancers involves a combination of chemotherapy, radiation, and surgery. EUS is very useful for staging of the tumour and nodes. High frequency ultrasound miniprobes provide the ability to perform staging when the lesion is obstructing the oesophageal lumen. CT and PET provide valuable information regarding node and metastasis staging.

    Weight loss and malnutrition are common in cancer patients. Although weight loss is predominantly due to loss of fat mass, the morbidity risk is given by the decrease in muscle mass. The assessment of nutritional status is essential for a diagnosis of nutritional compromise and required for the multidisciplinary approach. Subjective global assessment (SGA) is made by the patients nutritional symptoms and weight loss. The objective assessment, a significant weight loss (>10%) for 6 months is considered an indicator of nutritional deficiency. The mean body index, body fat mass and body protein mass are decreased as cancer stage increases. The biochemical data of albumin, cholesterol, triglyceride, Zn, transferrin, total lymphocyte count are decreased in advanced cancer stage. Daily energy intake, cabohyderate and Vit B1 intake is decreased according to cancer stage. The patients are divided into three groups according to SGA. The three groups showed a significant difference in body weight, 1 month weight loss%, 6 month weight loss%, body mass index, mid arm circumference, albumin, energy intake, as well as carbohyderate intake protein and energy malnutrition. Nutritional assessment is of great importance because undernutrition has been shown to be associated with increase in stomach cancer associated morbidity and mortality. The authors concluded that nutritional assessment should be done in cancer patients preoperatively, and with adequate nutritional support, the morbidity and mortality would be decreased.

    Purpose: To evaluate the accuracy of pre-operative MRI for the detection of optic nerve invasion in retinoblastoma. Materials and methods: Institutional review board approval and informed consent were waived for this retrospective study. A total of 41 patients were included. Inclusion criteria were histologically proven retinoblastoma, availability of diagnostic-quality preoperative MR images acquired during the 4 weeks before surgery, unilateral retinoblastoma, and normal-sized optic nerve. Two radiologists retrospectively reviewed the MR images independently. Five imaging findings (diffuse mild optic nerve enhancement, focal strong optic nerve enhancement, optic sheath enhancement, tumor location, and tumor size) were evaluated against optic nerve invasion of retinoblastoma. The predictive performance of all MR imaging findings for optic nerve invasion was also evaluated by the receiver operating characteristic curve analysis. Results: Optic nerve invasion was histopathologically confirmed in 24% of study population (10/41). The differences in diffuse mild enhancement, focal strong enhancement, optic sheath enhancement, and tumor location between patients with optic nerve invasion and patients without optic nerve invasion were not significant. Tumor sizes were 16.1 mm (SD: 2.2 mm) and 14.9 mm (SD: 3.6 mm) in patients with and without optic nerve involvement, respectively (P = 0.444). P-Values from binary logistic regression indicated that all five imaging findings were not significant predictors of tumor invasion of optic nerve. The AUC values of all MR imaging findings for the prediction of optic nerve invasion were 0.689 (95% confidence interval: 0.499–0.879) and 0.653 (95% confidence interval: 0.445–0.861) for observer 1 and observer 2, respectively. Conclusion: Findings of MRI in patients with normal-sized optic nerves have limited usefulness in preoperatively predicting the presence of optic nerve invasion in retinoblastoma.

    To develop and evaluate the efficacy of an online continuing education course for professionals who provide food safety information to high-risk populations. A 2-credit graduate-level class was converted into six web-based modules (overview of foodborne illness, immunology, pregnancy, human immunodeficiency virus, cancer and transplants, and lifecycle) and offered to nutrition and health professionals. Participants had 8 weeks to complete the modules, pre and post questionnaires, and course evaluation. Those who successfully completed the protocol received six continuing education units from one of three professional associations. Change in knowledge was measured using pre and post questionnaires. Course efficacy was evaluated using a post-course questionnaire. A convenience sample of 140 registered dietitians/dietetic technicians registered, nurses, and extension educators were recruited through professional conferences and electronic mailing lists to take the course. Analysis of variance was used to evaluate differences in knowledge scores for all groups across five main effects (attempt, module, profession, age, and education). Course evaluation responses were used to assess course effectiveness. For each module, knowledge scores increased significantly (PRisk Populations," seem to be a convenient, effective option for dietetics professionals, nurses, and extension educators seeking knowledge about food safety issues of high-risk populations.

    Pleurotus ostreatus was grown on paddy straw as well as other vegetable and agricultural wastes i.e. pea pod shell, cauliflower leaves, radish leaves and brassica straw in various combinations with paddy straw. The mushroom did not grow on the vegetable wastes separately. The cumulative yield and biological efficiency of the edible oyster mushroom P. ostreatus grown on substrate containing paddy straw in various combinations with different vegetable wastes i.e. 20% and 30 % vegetable wastes mixed with 80% and 70% (w/w) of paddy straw was found to be better, when compared with yield and biological efficiency obtained on paddy straw (100%) alone. The protein content and six essential amino acid contents (Leu, Ile, Val, Thr, Met, Phe) showed a significant increase and total sugar and reducing sugar contents showed decrease in the mushroom fruit bodies grown at different combinations of vegetable wastes with paddy straw as compared to paddy straw alone. However, there was not any significant change in moisture content of mushroom cultivated on different groups of wastes. Hence, results of this investigation suggest that the vegetable wastes which are generally left to rot in situ in many cities and villages causing outbreak of diseases can be bioremediated by edible mushroom P. ostreatus. The added advantage is that we get edible mushroom fruit body with improved nutrition.

    Full Text Available Abstract Nutritional depletion has been demonstrated to be a major determinant of the development of post-operative complications. Gastrointestinal surgery patients are at risk of nutritional depletion from inadequate nutritional intake, surgical stress and the subsequent increase in metabolic rate. Fears of postoperative ileus and the integrity of the newly constructed anastomosis have led to treatment typically entailing starvation with administration of intravenous fluids until the passage of flatus. However, it has since been shown that prompt postoperative enteral feeding is both effective and well tolerated. Enteral feeding is also associated with specific clinical benefits such as reduced incidence of postoperative infectious complications and an improved wound healing response. Further research is required to determine whether enteral nutrition is also associated with modulation of gut function. Studies have indicated that significant reductions in morbidity and mortality associated with perioperative Total Parenteral Nutrition (TPN are limited to severely malnourished patients with gastrointestinal malignancy. Meta-analyses have shown that enteral nutrition is associated with fewer septic complications compared with parenteral feeding, reduced costs and a shorter hospital stay, so should be the preferred option whenever possible. Evidence to support pre-operative nutrition support is limited, but suggests that if malnourished individuals are adequately fed for at least 7–10 days preoperatively then surgical outcome can be improved. Ongoing research continues to explore the potential benefits of the action of glutamine on the gut and immune system for gastrointestinal surgery patients. To date it has been demonstrated that glutamine-enriched parenteral nutrition results in reduced length of stay and reduced costs in elective abdominal surgery patients. Further research is required to determine whether the routine supplementation of

    Full Text Available Background: Health professionals play a key role in the delivery of nutrition interventions. Improving the quality of nutrition training in health professional schools is vital for building the necessary human resource capacity to implement effective interventions for reducing malnutrition in West Africa. This study was undertaken to assess the current status of nutrition training in medical, nursing and midwifery schools in West Africa. Design: Data were collected from 127 training programs organized by 52 medical, nursing, and midwifery schools. Using a semi-structured questionnaire, we collected information on the content and distribution of nutrition instruction throughout the curriculum, the number of hours devoted to nutrition, the years of the curriculum in which nutrition was taught, and the prevailing teaching methods. Simple descriptive and bivariate analyses were performed. Results: Nutrition instruction occurred mostly during the first 2 years for the nursing (84%, midwifery (87%, and nursing assistant (77% programs and clinical years in medical schools (64%. The total amount of time devoted to nutrition was on average 57, 56, 48, and 28 hours in the medical, nursing, midwifery, and nursing assistant programs, respectively. Nutrition instruction was mostly provided within the framework of a dedicated nutrition course in nursing (78%, midwifery (87%, and nursing assistant programs (100%, whereas it was mainly embedded in other courses in medical schools (46%. Training content was heavily weighted to basic nutrition in the nursing (69%, midwifery (77%, and nursing assistant (100% programs, while it was oriented toward clinical practice in the medical programs (64%. For all the programs, there was little focus (<6 hours contact time on public health nutrition. The teaching methods on nutrition training were mostly didactic in all the surveyed schools; however, we found an integrated model in some medical schools (12%. None of the

    2011-09-01

    Enhanced recovery programmes have been studied in randomised trials with evidence of quicker recovery of gut function, reduced morbidity, mortality and hospital stay and improved physiological and nutritional outcomes. They aim to reduce the physiological and psychological stress of surgery and consequently the uncontrolled stress response. The key elements, reduced pre-operative fasting, intravenous fluid restriction and early feeding after surgery, are in conflict with traditional management plans but are supported by strong clinical evidence. Given the strength of the current data enhanced recovery should now be the standard of care.

    National guidelines do not support preoperative body washing to reduce surgical site infections, instead recommending bathing or showering with soap. Yet preoperative body washing continues to be widely used in many hospitals across Europe. This paper suggests that existing trials of preoperative body washing, upon which guidelines are based, are dated and proposes a new investigation of preoperative body washing using modern definitions of surgical site infection with standardised patient follow up, modern surgical techniques and well designed trials. This paper provides a critique of existing guidelines and describes a randomised trial with 60 participants to compare the effect of soap and two antiseptic washing products on colony forming units (CFUs) for up to six hours. Chlorhexidine gluconate and octenidine were significantly more effective than soap in reducing CFUs in the underarm, and chlorhexidine was significantly more effective than soap in reducing CFUs in the groin.

    We developed and validated a prediction rule for the occurrence of early postoperative severe pain in surgical inpatients, using predictors that can be easily documented in a preoperative setting. A cohort of surgical inpatients (n=1416) undergoing various procedures except cardiac surgery and intracranial neurosurgery in a University Hospital were studied. Preoperatively the following predictors were collected: age, gender, type of scheduled surgery, expected incision size, blood pressure, heart rate, Quetelet index, the presence and severity of preoperative pain, health-related quality of life the (SF-36), Spielberger's State-Trait Anxiety Inventory (STAI) and the Amsterdam Preoperative Anxiety and Information Scale (APAIS). The outcome was the presence of severe postoperative pain (defined as Numeric Rating Scale > or =8) within the first hour postoperatively. Multivariate logistic regression in combination with bootstrapping techniques (as a method for internal validation) was used to derive a stable prediction model. Independent predictors of severe postoperative pain were younger age, female gender, level of preoperative pain, incision size and type of surgery. The area under the receiver operator characteristic (ROC) curve was 0.71 (95% CI: 0.68-0.74). Adding APAIS scores (measures of preoperative anxiety and need for information), but not STAI, provided a slightly better model (ROC area 0.73). The reliability of this extended model was good (Hosmer and Lemeshow test p-value 0.78). We have demonstrated that severe postoperative pain early after awakening from general anesthesia can be predicted with a scoring rule, using a small set of variables that can be easily obtained from all patients at the preoperative visit. Before this internally validated preoperative prediction rule can be applied in clinical practice to support anticipatory pain management, external validation in other clinical settings is necessary.

    The human-derived potential probiotic strain Lactobacillus rhamnosus CTC1679 was used as a starter culture in reduced fat and sodium low-acid fermented sausages (fuets) to assess its ability to survive through the gastrointestinal tract (GIT) in a human intervention study consisting of 5 healthy volunteers who consumed 25 g fuet a day for 21 days. Faecal samples were analysed during and after consumption. L. rhamnosus CTC1679 produced a transient colonisation of the human GIT and persisted during the ingestion period of fuet containing L. rhamnosus CTC1679 at levels ca. 8log CFU/g. After 3 days of non-consumption, the strain was still recovered in the faeces of all the volunteers. To evaluate the safety of the nutritionally enhanced manufactured fuets, a challenge test was designed in a separately manufactured batch. L. rhamnosus CTC1679 was able to grow, survive and dominate (levels ca. 10(8) CFU/g) the endogenous lactic acid bacteria (LAB), prevented the growth of Listeria monocytogenes throughout the whole ripening process of the fuets and eliminated Salmonella. After 35 days of storage at 4 °C, L. monocytogenes was not detected, achieving absence in 25 g of the product. The application of high hydrostatic pressure (HHP) treatment (600 MPa for 5 min) at the end of ripening (day 14) produced an immediate reduction of L. monocytogenes to levels fermented sausages.

    Current trends in population growth and consumption patterns continue to increase the demand for wheat, a key cereal for global food security. Further, multiple abiotic challenges due to climate change and evolving pathogen and pests pose a major concern for increasing wheat production globally. Triticeae species comprising of primary, secondary, and tertiary gene pools represent a rich source of genetic diversity in wheat. The conventional breeding strategies of direct hybridization, backcrossing and selection have successfully introgressed a number of desirable traits associated with grain yield, adaptation to abiotic stresses, disease resistance, and bio-fortification of wheat varieties. However, it is time consuming to incorporate genes conferring tolerance/resistance to multiple stresses in a single wheat variety by conventional approaches due to limitations in screening methods and the lower probabilities of combining desirable alleles. Efforts on developing innovative breeding strategies, novel tools and utilizing genetic diversity for new genes/alleles are essential to improve productivity, reduce vulnerability to diseases and pests and enhance nutritional quality. New technologies of high-throughput phenotyping, genome sequencing and genomic selection are promising approaches to maximize progeny screening and selection to accelerate the genetic gains in breeding more productive varieties. Use of cisgenic techniques to transfer beneficial alleles and their combinations within related species also offer great promise especially to achieve durable rust resistance. PMID:27458472

    Full Text Available Nutritional requirements can contribute considerably to the production cost and the bioprocess economics. Media optimisation using response surface methodology is one of the used methods to ameliorate the bioprocess economics. In the present study, biosurfactant production by Bacillus subtilis SPB1 was effectively enhanced by response surface methodology. A Plackett-Burman-based statistical screening procedure was adopted to determine the most important factor affecting lipopeptide production. Eleven variables are screened and results show that glucose, K2HPO4, and urea concentrations influence the most biosurfactant production. A Central Composite Design was conducted to optimize the three selected factors. Statistical analyses of the data of model fitting were done by using NemrodW. Results show a maximum predicted biosurfactant concentration of 2.93 (±0.32 g/L when using 15 g/L glucose, 6 g/L urea, and 1 g/L K2HPO4. The predicted value is approximately 1.65 much higher than the original production determined by the conventional one-factor-at-a-time optimization method.

    Seven years ago Hygie published an article on the limits of conventional nutrition education in urban Africa. Strategies and methods in communication for nutrition have since evolved, incorporating results of international research to develop innovative, highly participative approaches. In this article the authors provide an extensive analysis of the different methodologies used in nutrition education programmes, in particular the KAB, social marketing, and community participation models, indicating main areas where each method used separately has failed. Members of the African Nutritional Education Network (RENA) have studied the above mentioned approaches, modifying them or integrating certain elements to adopt a more effective approach, which they consider somewhat as the management of social communication for nutrition education. Needs assessments and programme planning are largely enhanced by a causal analysis component specific to nutrition education in a community setting which has been developed by the authors. Other classic elements of programme implementation such as community participation, diversity of methods and intervention, are then combined with a multi-level/multi-actor evaluation processes to produce what the authors esteem to be a more effective nutrition education programme. They conclude, however, with the warning that although behavioural modifications brought about by nutrition communication and education might be beneficial for public health, they could have different, possibly adverse effects on other aspects of society. Effective nutrition education must therefore be included in a more extensive field of health promotion by acting on the multiple factors which influence the nutrition and health state of vulnerable groups.

    Abstract Purpose: To describe the clinical, imaging, and pathologic characteristics and diagnostic methods of telangiectatic osteosarcoma (TOS) for improving the diagnostic level. Materials and methods: The authors retrospectively reviewed patient demographics, serum alkaline phosphatase (AKP) levels, preoperative biopsy pathologic reports, pathologic materials, imaging findings, and treatment outcomes from 26 patients with TOS. Patient images from radiography (26 cases) and magnetic resonance (MR) imaging (22 cases) were evaluated by 3 authors in consensus for intrinsic characteristics. There were 15 male and 11 female patients in the study, with an age of 9–32 years (mean age 15.9 years). Results: Eighteen of 26 patients died of lung metastases within 5 years of follow-up. The distal femur was affected more commonly (14 cases, 53.8%). Regarding serum AKP, normal (8 cases) or mildly elevated (18 cases) levels were found before preoperative chemotherapy. Radiographs showed geographic bone lysis without sclerotic margin (26 cases), cortical destruction (26 cases), periosteal new bone formation (24 cases), soft-tissue mass (23 cases), and matrix mineralization (4 cases). The aggressive radiographic features of TOS simulated the appearance of conventional high-grade intramedullary osteosarcoma, though different from aneurysmal bone cyst. MR images demonstrated multiple big (16 cases) or small (6 cases) cystic spaces, fluid-fluid levels (14 cases), soft-tissue mass (22 cases), and thick peripheral and septal enhancement (22 cases). Nine of 26 cases were misdiagnosed as aneurysmal bone cysts by preoperative core-needle biopsy, owing to the absence of viable high-grade sarcomatous cells in the small tissue samples. Conclusion: The aggressive growth pattern with occasional matrix mineralization, and multiple big or small fluid-filled cavities with thick peripheral, septal, and nodular tissue surrounding the fluid-filled cavities are characteristic imaging features of

    Among the downstream targets of calcium in plants, calcium-dependent protein kinases (CDPKs) form an interesting class of kinases which are activated by calcium binding. They have been implicated in a diverse array of responses to hormonal and environmental stimuli. In order to dissect the role of CDPKs in the moss Funaria hygrometrica, a polymerase chain reaction (PCR)-based approach was adopted to clone the gene. Using degenerate PCR primers against conserved regions of CDPKs, a 900 bp amplicon was obtained from the genomic DNA of Funaria. Southern hybridization under low stringency conditions indicated the presence of several CDPK related sequences in the Funaria genome. This observation is consistent with reports of multigene families of CDPKs in other plants. The 900 bp fragment was subsequently used to isolate a 2.2 kb partial genomic clone of the CDPK gene from Funaria. The genomic clone encodes an open reading frame (ORF) of 518 amino acids. Interestingly, unlike other CDPK genes from plants, the entire 1.5 kb ORF is not interrupted by introns. The deduced amino acid sequence of the Funaria gene shows extensive homology with CDPKs from higher plants, 73% identity with the Fragaria CDPK and 71% identity with CDPK isoform 7 of Arabidopsis. Phylogenetic analysis revealed that the Funaria CDPK is closer to the CDPKs from higher plants like strawberry and Arabidopsis as compared to those from lower plants such as the liverwort Marchantia, the green alga Chlamydomonas or another moss Tortula. Northern analysis shows enhanced expression of the CDPK transcript within 24–48 h of starvation for nitrogen, phosphorus or sulphur. So far the only other kinase which is known to be induced by nutrient starvation in plants is the wpk 4 which is a snf-1 related kinase (SnRKs). To our knowledge this is the first report that implicates a CDPK in the starvation response.

    This study used a theoretical model to determine whether an efficacy-enhancing teaching protocol was effective in improving immediate postoperative behaviors and selected short- and long-term health outcomes in women who underwent abdominal hysterectomies. The model used was the self-efficacy theory of Albert Bandura, PhD. One hundred eight patients in a 486-bed teaching hospital in the Midwest who underwent hysterectomies participated. The participation rate was 85%, and the attrition rate was 17% during the six-month study. The major finding was that participants in the efficacy-enhancing teaching group ambulated significantly longer than participants in the usual care group. This is an important finding because the most prevalent postoperative complications after hysterectomy are atelectasis, pneumonia, paralytic ileus, and deep vein thrombosis, and postoperative ambulation has been shown to decrease or prevent all of these complications. This finding could affect the overall health status of women undergoing hysterectomies.

    Cancer patients have the highest incidence of protein-calorie malnutrition seen in hospitalized patients, with significant malnutrition occurring in more than 30% of cancer patients undergoing major upper gastrointestinal procedures. Clinically significant malnutrition occurs as a result of diminished nutrient intake, increased nutrient losses, and tumor-induced derangements in host metabolism. In the absence of adequate exogenous nutrients, the body utilizes endogenous substrates to satisfy the ongoing requirements of both host and tumor for energy and protein. In those patients with malignant obstruction of the gastrointestinal tract, the tumor itself may induce diminished nutrient intake. Present day treatment modalities including gastrointestinal resection, chemotherapy, and radiotherapy compound these metabolic derangements, further increasing the risk of postoperative morbidity and death. The presence of malnutrition in cancer patients has prognostic importance. In a review of more than 3000 cancer patients, DeWys and colleagues identified significantly improved survival in those patients without weight loss compared with those had lost 6% of their body weight (Am J Med 69:491-497, 1980). Other investigators have noted increased postoperative morbidity and mortality associated with malnutrition. Early hypotheses suggested that reversal of weight loss would improve survival. The development and refinements of enteral and parenteral nutrition have provided the opportunity for studying the relationship between nutritional supplementation and postoperative prognosis. Nutrition support is therefore often instituted to improve nutritional status and thereby reduce the risks of postoperative complications. This article addresses the beneficial role of preoperative nutrition therapy in cancer patients.

    Full Text Available Background: Although nutritional supplementation is established in surgicalpractice, studies on feeding patients undergoing pancreaticoduodenectomy utilize widely disparate protocols, include small numbers of patients and have disparate endpoints. The aim of this study is to carry out a systematic review of peri-operative nutritional supplementation in patients undergoing pancreaticoduodenectomy in order to identify consistent themes. Methods :Searches of the MEDLINE and EMBASE databases yielded 10 studies examining nutritional support in 571 patients undergoing pancreaticoduodenectomy. Data were retrieved on: proportion of pre-operative weight loss, biochemical parameters (preoperative albumin and the presence of jaundice, type and duration of nutritional support and clinical outcome (morbidity, mortality and hospital stay. Results: Pre-operative percentage weight loss was similar in all studies evaluated. Routine post-operative total parenteral nutrition (TPN was associated with a higher incidence of complications. Enteral nutrition reduced infective complications. Cyclical nutrition was associated with a lower incidence of postoperative gastric stasis. Conclusion :Clear themes emerge from this systematic review. Patients undergoing pancreaticoduodenectomy are nutritionally depleted at the time of surgery and the preoperative period may present a window for intervention. Routine TPN is not beneficial. Routine post-operative enteral nutritional support, delivered on a cyclical basis appears to be the optimal mode of delivery.

    Full Text Available To date no studies have been published on preoperative education forpatients who had lumbar surgery. The aim of this study was to determine if there is a demand for preoperative education for patients who had lumbar surgery for radiculopathy. A convenience sample of 47 patients who had lumbar surgery and a random sample of 141 physiotherapists involved in treating patients who had lumbar surgery completed a newly developed spinal surgery questionnaire. The data were analyzed using descriptiveand inferential statistical tests. Results showed that 100% of the patients and 99% of therapists view preoperative education to be an important component for lumbar surgery for radiculopathy. The most important factors identifiedfor inclusion in preoperative educational programs were reason for surgery, risks associated with surgery, limitations following surgery and more education regarding pain. The preferred method of education delivery was verbal one-on-one education. This study demonstrates that there is a demand for preoperative education for patients who had lumbar surgery.

    Lung complications are the most frequent causes of postoperative morbidity-mortality, especially in lung disease patients. So, those patients should be preoperatively carefully evaluated and prepared, both clinically and laboratorially. This review aimed at determining surgical risk and at establishing preoperative procedures to minimize peri and postoperative morbidity-mortality in lung disease patients. Major anesthetic-surgical repercussions in lung function have already been described. Similarly, we tried to select higher-risk patients, submitted or not to lung resection. To that end, clinical and laboratorial propedeutics were used. Finally, a proposal of a preoperative algorithm was presented for procedures with lung resection. Lung disease patients, especially those with chronic evolution, need to be preoperatively thoroughly evaluated. ASA physical status and Goldmans cardiac index are important risk forecasting factors for lung disease patients not candidates for lung resection. Adding to these criteria, estimated postoperative max VO2, FEV1 and diffusion capacity are mandatory for some patients submitted to lung resection. beta2-agonists and steroids should be considered in the preoperative period of these patients.

    Full Text Available Due to higher energy consumption, physically active people have higher nutritional requirements. In addition to other important factors for sports, such as good health and physical predisposition, adequate nutrition is a fundamental component. Sports nutrition must be well planned and individually adapted based on physical characteristics, tendencies towards gaining or losing weight, frequency, duration and intensity of training sessions. Studies have shown that a well-balanced ratio of macro and micronutrients, with the support of supplements and adequate hydration, can significantly improve athletic performance and plays a key role in achieving better results. An optimally designed nutritional program, with realistic and achievable goals, which complements a well-planned training program, is the basis for success in sports. Only when nutritional requirements are met, deficits can be prevented and performance in sport pushed to the limit.

    Fresh pork sausages (pork shoulder, pork back fat, water, rusk and seasoning) were manufactured where 15% of the pork back fat was substituted with linseed oil (LO) or fish oil (FO). Green tea catechins (GTC) and green coffee antioxidant (GCA) were added to both LO (LGTC 200 and LGCA 200) and FO (FGTC 200 and FGCA 200) substituted sausages at a level of 200mg/kg. Raw and cooked pork sausages were either over-wrapped with oxygen permeable film (aerobic storage) or stored in modified atmosphere packages (MAP) containing 80% O(2):20% CO(2) or 70% N(2):30% CO(2), respectively for 7 days at 4°C. Effects on fatty acid profiles, lipid oxidation, colour and sensorial properties were investigated. α-Linolenic acid increased from 1.34% (control) to 8.91% (LO) and up to 11.2% (LGTC 200 and LGCA 200). Addition of fish oil increased levels of EPA from 0.05% (control) to 2.83% (FO), 3.02% (FGTC 200) and 2.87% (FGCA 200) and DHA levels increased from 0.04% (control) to a maximum of 1.93% (FGTC 200). Lipid oxidation was low in raw and cooked linseed oil containing sausages. GTC (200mg/kg) significantly (Pfish oil containing sausages after 7 days of storage. Colour parameters in raw pork sausages were unaffected by the packaging atmosphere. L(∗) lightness values were lower (Pfish oil containing sausages were improved by GTC addition. Results obtained demonstrate potential for the production of nutritionally enhanced fresh pork sausages.

    Purpose: To assess the clinical value of retrospective image fusion of neck MRI and {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) PET for locoregional extension and nodal staging of neck cancer. Materials and methods: Thirty patients with carcinoma of the oral cavity or hypopharynx underwent PET/CT and contrast-enhanced neck MRI for initial staging before surgery including primary tumor resection and neck dissection. Diagnostic performance of PET/CT, MRI, and retrospective image fusion of PET and MRI (fused PET/MRI) for assessment of the extent of the primary tumor (T stage) and metastasis to regional lymph nodes (N stage) was evaluated. Results: Accuracy for T status was 87% for fused PET/MRI and 90% for MRI, thus proving significantly superior to PET/CT, which had an accuracy of 67% (p = 0.041 and p = 0.023, respectively). Accuracy for N status was 77% for both fused PET/MRI and PET/CT, being superior to MRI, which had an accuracy of 63%, although the difference was not significant (p = 0.13). On a per-level basis, the sensitivity, specificity and accuracy for detection of nodal metastasis were 77%, 96% and 93% for both fused PET/MRI and PET/CT, compared with 49%, 99% and 91% for MRI, respectively. The differences for sensitivity (p = 0.0026) and accuracy (p = 0.041) were significant. Conclusion: Fused PET/MRI combining the individual advantages of MRI and PET is a valuable technique for assessment of staging neck cancer.

    To investigate the effect of exposure to a virtual reality (VR) environment preoperatively on patient-reported outcomes for surgical operations. There is a scarcity of well-developed quality improvement initiatives targeting patient satisfaction. We performed a randomized controlled trial of patients undergoing cranial and spinal operations in a tertiary referral center. Patients underwent a 1:1 randomization to an immersive preoperative VR experience or standard preoperative experience stratified on type of operation. The primary outcome measures were the Evaluation du Vecu de l'Anesthesie Generale (EVAN-G) score and the Amsterdam Preoperative Anxiety and Information (APAIS) score, as markers of the patient's experience during the surgical encounter. During the study period, a total of 127 patients (mean age 55.3 years, 41.9% females) underwent randomization. The average EVAN-G score was 84.3 (standard deviation, SD, 6.4) after VR, and 64.3 (SD, 11.7) after standard preoperative experience (difference, 20.0; 95% confidence interval, CI, 16.6-23.3). Exposure to an immersive VR experience also led to higher APAIS score (difference, 29.9; 95% CI, 24.5-35.2). In addition, VR led to lower preoperative VAS stress score (difference, -41.7; 95% CI, -33.1 to -50.2), and higher preoperative VAS preparedness (difference, 32.4; 95% CI, 24.9-39.8), and VAS satisfaction (difference, 33.2; 95% CI, 25.4-41.0) scores. No association was identified with VAS stress score (difference, -1.6; 95% CI, -13.4 to 10.2). In a randomized controlled trial, we demonstrated that patients exposed to preoperative VR had increased satisfaction during the surgical encounter. Harnessing the power of this technology, hospitals can create an immersive environment that minimizes stress, and enhances the perioperative experience.

    Nutritional status of patients significantly affects the outcome of surgical treatment, whether it's about being obese or malnutrition with loss of muscle mass. Inadequate nutritional support in the perioperative period compromises surgical procedures even in patients who are adequately nourished. In this paper, particular attention was paid to malnourished patients, and their incidence in population hospitalized in surgical wards can be high up to 30%. Special emphasis was paid to the appropriateness of preoperative fasting and to the acceptance of new knowledge in this area of treatment. The aim of this working group was to make guidelines for perioperative nutritional support with different modalities of enteral nutrition. The development of these guidelines was attended by representatives of Croatian Medical Association: Croatian Society for Digestive Surgery, Croatian Society for Clinical Nutrition, Croatian Society of Surgery, Croatian Society for Endoscopic Surgery, Croatian Trauma Society and the Croatian Society of Anesthesiology and Intensive Care. The guidelines are designed as a set of questions that arise daily in clinical practice when preparing patients for surgery and after the surgical treatment, which relate to the assessment of nutritional status, perioperative nutritional support, duration of preoperative fasting period and the selection of food intake route. Assessment of nutritional status and the use of different modes of enteral nutrition should enter into standard protocols of diagnosis and treatment in the Croatian hospitals.

    Protein-energy malnutrition is frequently seen in patients with end-stage liver disease who undergo liver transplantation. This causes a deterioration of the patients' clinical condition and affects their post-transplantation survival. Accurate assessment of the nutritional status and adequate intervention are prerequisites for perioperative nutritional treatment. However, the metabolic abnormalities induced by liver failure make the traditional assessment of the nutritional status difficult. The methods that were recently developed for accurately assessing the nutritional status by body bioelectrical impedance may be implemented in pre-transplant management. Because preoperative malnutrition and the loss of skeletal muscle mass, called sarcopenia, have a significant negative impact on the post-transplantation outcome, it is essential to provide adequate nutritional support during all phases of liver transplantation. Oral nutrition is preferred, but tube enteral nutrition may be required to provide the necessary caloric intake. We herein discuss both bioelectrical impedance and the latest findings in the current perioperative nutritional interventions in liver transplant patients regarding synbiotics, micronutrients, branched-chain amino acid supplementation, the use of immune system modulating formulas, the fluid balance and the offering of nocturnal meals.

    Nutritional therapy for cancer patients includes various objectives such as improvement of cachexia, elucidation of the mechanism of malnutrition, development of therapy for anorexia, nutrition support during chemotherapy or radiotherapy, and inhibition of tumor growth under controlled caloric intake. This review describes recent remarkable developments in nutritional therapy for cancer patients. Cytokines such as interleukin (IL)-1, IL-6, and tumor necrosis factor which induce proteolysis and lipolysis are involved in the cause of malnutrition and cachexia in cancer patients. IL-1 also plays a significant role in the development of cancer anorexia via direct action in the brain. For anorexia therapy, progestogens have been shown to improve appetite and food intake in cancer patients. Moreover, glutamine supplementation improves the host protein metabolism without enhancement of tumor growth during chemotherapy. Among the effects of caloric intake on anticancer therapy, AO-90, a methionine-free intravenous amino acid solution, has been shown to increase the antitumor effect of 5-fluorouracil in clinical studies. From these observations, recent progress in nutritional therapy for cancer patients has been remarkable. Further study of nutritional therapy is required in order to maintain or improve the quality of life of cancer patients in the future.

    Optimal nutrition will be critical for crew members who embark on space exploration missions. Nutritional assessment provides an opportunity to ensure that crewmembers begin their missions in optimal nutritional status, to document changes during a mission and, if necessary, to provide intervention to maintain that status throughout the mission, and to assesses changes after landing in order to facilitate the return to their normal status as soon as possible after landing. We report here the findings from our nutritional assessment of astronauts who participated in the International Space Station (ISS) missions, along with flight and ground-based research findings. We also present ongoing and planned nutrition research activities. These studies provide evidence that bone loss, compromised vitamin status, and oxidative damage are the critical nutritional concerns for space travelers. Other nutrient issues exist, including concerns about the stability of nutrients in the food system, which are exposed to longterm storage and radiation during flight. Defining nutrient requirements, and being able to provide and maintain those nutrients on exploration missions, will be critical for maintaining crew member health.

    Since 1970s, the economic and social development in South Korea, as well as dietary pattern, has undergone various changes. Concerns for the decreased nutrition quality and physical activities among Koreans, especially young population, call for a need of a holistic approach in national food and nutrition policy. The National Health Promotion Act of 1995 included national interventions and programs to deal with nutrition-related chronic diseases and obesity prevention. A nation-wide monitoring system, which includes nutrition and health examination survey, is being built and run by the Ministry of Health and Welfare and its affiliated organizations every three years. The Korea Food and Drug Administration (KFDA) is another key agency undertaking national food and nutrition policies. The KFDA recently promulgated the national strategic plans for improving food safety and nutrition, focusing on children. Nutrition labelling policy for processed food is managed by KFDA and various education programs are developed and disseminated to enhance the awareness of nutrition labelling. The agency also makes standards and regulates foods for special dietary uses and health functional food. The Rural Development Administration (RDA) is responsible for maintaining the food composition database. Finally, the National School Lunch Program is mainly governed by the Ministry of Education and Human Resources Development. The above central government agencies along with regional health centers are making efforts to promote the healthy eating habits in addition to constructing healthy environment by making laws and programs and by research and social marketing.

    Stimulated by the explosive expansion of the computerized desk top publishing industry during the past few years, microcomputer hardware and software are evolving at a staggering rate. Memory is rapidly increasing, and prices are declining. I have found that with the hardware and software described in this paper, I was able to obtain, in a much more cost-effective manner, as useful preoperative information for my practice as I could obtain with more expensive "turnkey" (only one use) computerized imaging systems. This type of microcomputer, of course, is not limited to just the imaging system, but can be used for a variety of other programs as well, such as word processing, slide labeling and production, spreadsheet functions, billing and filing, and numerous business and other applications. The ease of use with readily available 35-mm slides of my patients has greatly enhanced the appeal of this system. Computerized imaging, when used as an educational tool, can be very helpful in preoperative planning, resident teaching, and for illustration and discussion of a patient's proposed surgery. The electronic imaging disclaimer compiled by the American Society of Plastic and Reconstructive Surgeons has been extremely helpful in clarifying the limits of computerized imaging and reducing any false expectations that my patients might have. All of us are experiencing the dawn of a very exciting evolution.

    The perioperative morbidity of diabetic patients is related to preoperative end-organ damage. Due to the microvascular pathology, autonomic neuropathy is common and cardiovascular abnormalities such as hypertension, painless myocardial ischemia, and orthostatic hypotension may predispose patients to perioperative cardiovascular instability. Autonomic dysfunction also contributes to delayed gastric emptying, and preoperative administration of a histamine antagonist and a gastric emptying agent is needed. Chronic hyperglycemia leads to glycosylation of tissue proteins and the accumulation of abnormal collagen can cause stiff joint syndrome resulting in difficult tracheal intubation. The primary goal of pre and intraoperative blood glucose control is to avoid hypoglycemia and ketosis. Moreover, the tight glycemic control has been reported to improve survival in critically ill patients who were treated in the intensive care unit.

    Mucocele of the appendix is an infrequent entity, characterized by distension of the lumen due to accumulation of mucoid substance and is rarely diagnosed preoperatively. If untreated, mucocele may rupture producing a potentially fatal entity known as pseudomyxoma peritonei. The type of surgical treatment is related to the dimensions and the histology of the mucocele. Appendectomy is used for simple mucocele or for cystadenoma. Right hemi-colectomy is recommended for cystadeno carcinoma. In this paper, we report a case of an asymptomatic 37-year-old woman in whom mucocele was found on a routine ultrasound examination and preoperative computed tomography scan. Surgery revealed a big appendix measuring 84 mm in length and 40 mm in diameter. The final pathologic diagnosis was simple mucocele. Celsius.

    Malnutrition and its associated complications are a considerable issue for surgical patients with upper gastrointestinal and colorectal cancer. The present study aimed to determine whether specific perioperative nutritional practices and protocols are associated with improved patient outcomes in this group. Patients admitted for elective upper gastrointestinal or colorectal cancer surgery (n = 95) over a 19-month period underwent a medical history audit assessing weight changes, nutritional intake, biochemistry, post-operative complications and length of stay. A subset of patients (n = 25) underwent nutritional assessment by subjective global assessment prior to surgery in addition to assessment of post-operative medical outcomes, nutritional intake and timing of dietetic intervention. Mean (SD) length of stay for patients was 14.0 (12.2) days, with complication rates at 35%. Length of stay was significantly longer in patients who experienced significant preoperative weight loss compared to those who did not [17.0 (15.8) days versus 10.0 (6.8) days, respectively; P nutritional assessment, 32% were classified as mild-moderately malnourished and 16% severely malnourished.

    Reducing anxiety is very important before operation. Preoperative visit and use of premedication are popular methods to achieve this goal, but the role of anxiolytic premedication remains unclear and postoperative side-effects may result from routine premedication. Citrus aurantium is used as an alternative medicine in some countries to treat anxiety, and recently the anxiolytic role of this medicinal plant was established in an animal model study. The aim of this study was to assess the anxiolytic effect of Citrus aurantium blossomon preoperative anxiety. We studied 60 ASA I patients undergoing minor operation. In a randomized double-blind design, two groups of 30 patients received one of the following oral premedication two hours before induction of anesthesia: 1) Citrus aurantium blossom distillate 1mL.kg(-1) (C-group); 2) Saline solution 1mL.kg(-1) as placebo (P-group). Anxiety was measured before and after premedication using the Spielberger state-trait anxiety inventory (STAI-state) and the Amsterdam preoperative anxiety and information scale (APAIS) before operation.

    2010-01-01

    Carotid body tumors (CBTs) are relatively frequent lesions encountered at high altitudes, such in as the Andean Mountains. A correct preoperative diagnosis is essential for surgical planning and performance. For this reason, we have reviewed the evolution of our experience in the imaging diagnosis of these tumors. Between 1980 and June 2008, 160 CBTs were diagnosed. A total of 138 tumors were operated on, 4 are waiting for surgery, and 18 were not operated on because of age, medical conditions, or patient refusal. We have reviewed retrospectively the modalities of imaging diagnosis in our patients who underwent operation. Among the 138 tumors operated on, a correct preoperative diagnosis was done in 127 cases (92%). The preoperative diagnosis of the remaining 11 patients was unspecified benign tumor for 6 patients and neck lymph node for 5 patients. The imaging methods performed by different radiologists were conventional ultrasound, color Doppler ultrasound, carotid conventional angiography (CA), axial tomography, magnetic resonance and magnetic resonance angiography, and computed tomographic angiography (CTA). Most patients had more than one image study. Review of radiologist reports revealed a correct diagnosis in all carotid CA, magnetic resonance studies, and CTA. Additionally, CTA appeared to be a valuable method to predict the Shamblin group. Clinical suspicion and current image techniques permit a correct diagnosis in practically all cases of CBT.

    Full Text Available The development of IgE-mediated allergic diseases is influenced by many factors, including genetic and environmental factors such as pollution and farming, but also by nutrition. In the last decade, substantial progress has been made in our understanding of the impact that nutrition can have on allergic diseases. Many studies have addressed the effect of breastfeeding, pre-, pro- and synbiotics, vitamins and minerals, fiber, fruit and vegetables, cow’s milk, and n-3 fatty acids, on the development of allergies. In addition, nutrition can also have indirect effects on allergic sensitization. This includes the diet of pregnant and breastfeeding women, which influences intrauterine development, as well as breastmilk composition. These include the diet of pregnant and breastfeeding women that influences intrauterine development as well as breastmilk composition, effects of food processing that may enhance allergenicity of foods, and effects via modulation of the intestinal microbiota and their metabolites. This editorial review provides a brief overview of recent developments related to nutrition and the development and management of allergic diseases.

    Pre-operative anaemia is common and occurs in up to 76% of patients. It is associated with increased peri-operative allogeneic blood transfusions, longer hospital lengths of stay and increased morbidity and mortality. Iron deficiency is one of the most common causes of this anaemia. Oral iron therapy has traditionally been used to treat anaemia but newer, safer parenteral iron preparations have been shown to be more effective in other conditions such as inflammatory bowel disease, chronic heart failure and post-partum haemorrhage. A limited number of studies look at iron therapy for the treatment of pre-operative anaemia. The aim of this Cochrane review is to summarise the evidence for use of iron supplementation, both enteral and parenteral, for the management of pre-operative anaemia. The objective of this review is to evaluate the effects of pre-operative iron therapy (enteral or parenteral) in reducing the need for allogeneic blood transfusions in anaemic patients undergoing surgery. We ran the search on 25 March 2015. We searched the Cochrane Injuries Group's Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), EMBASE Classic and EMBASE (Ovid), CINAHL Plus (EBSCO), PubMed, clinical trials registries, conference abstracts, and we screened reference lists. We included all randomised controlled trials (RCTs) which compared pre-operative iron monotherapy to placebo, no treatment, standard of care or another form of iron therapy for anaemic adults undergoing surgery. Anaemia was defined by haemoglobin values less than 13 g/dL for males and 12 g/dL for non-pregnant females. Data were collected by two authors on the proportion of patients who receive a blood transfusion, amount of blood transfused per patient (units) and haemoglobin measured as continuous variables at pre-determined time-points: pre

    In this study of 14 patients with anorectal anomalies CT and MRI were employed for preoperative assessment. The use of a pressure enhanced water soluble enema via the colostomy proved to be an extremely efficient method for showing a fistula. MRI studies were enhanced by the use of vaseline oil and in one case this technique was used prior to surgery to provide important information by injecting through a perineal fistula. CT and axial MRI proved to be more valuable than sagittal MRI which is only useful for the length of the atretic segment. The authors consider that a combined approach using pressure enhanced water soluble enema and MRI will provide the most valuable preoperative information to plan a successful operative approach and enable an accurate prognostic evaluation of continence in these difficult and complex patients.

    While the association between scoliosis and cardiac and respiratory function impairments has been well characterized in clinical practice and research, the potential effect of scoliosis on urinary tract structure and renal function has received little attention. Therefore, the purpose of this study was to evaluate the preoperative clinical characteristics of urinary tract structure and renal function in pediatric patients with idiopathic scoliosis, using a combination of blood tests, urinalysis, and imaging. Preoperative measures of urinary tract structure and renal function were obtained for 16 patients, 13-17 years old, scheduled for corrective surgery for idiopathic scoliosis. Preoperative assessment included blood test and urinalysis, combined with structural imaging on ultrasound (US), magnetic resonance imaging (MRI), magnetic resonance urography (MRU), and radioisotope tracing (RI), using technetium-99 m mercaptoacetyltriglycine ((99m) Tc-MAG3). Differences in blood and urine tests between patients with and without urinary tract obstruction (UTO) were evaluated for significance using Mann-Whitney U test. For all 16 patients, blood tests and MRU were within normal limits. Dilatation of the renal pelvis was identified on US in eight patients (50.0%). UTO was identified on RI in six patients (37.5%). UTO was associated with elevated β2-microglobulin concentration. Urinary β2-microglobulin concentration >0.7 μg/mg Cr differentiated patients with UTO from those without UTO, with a sensitivity of 100% and specificity of 70%. β2-Microglobulin concentration may be a useful marker to screen for asymptomatic UTO in patients with idiopathic scoliosis. © 2016 Japan Pediatric Society.

  18. Nutrition for adventure racing.

    2012-11-01

    Adventure racing requires competitors to perform various disciplines ranging from, but not limited to, mountain biking, running, kayaking, climbing, mountaineering, flat- and white-water boating and orienteering over a rugged, often remote and wilderness terrain. Races can vary from 6 hours to expedition-length events that can last up to 10-consecutive days or more. The purpose of this article is to provide evidence-based nutritional recommendations for adventure racing competitors. Energy expenditures of 365-750 kcal/hour have been reported with total energy expenditures of 18 000-80 000 kcal required to complete adventure races, and large negative energy balances during competitions have been reported. Nutrition, therefore, plays a major role in the successful completion of such ultra-endurance events. Conducting research in these events is challenging and the limited studies investigating dietary surveys and nutritional status of adventure racers indicate that competitors do not meet nutrition recommendations for ultra-endurance exercise. Carbohydrate intakes of 7-12 g/kg are needed during periods of prolonged training to meet requirements and replenish glycogen stores. Protein intakes of 1.4-1.7 g/kg are recommended to build and repair tissue. Adequate replacement of fluid and electrolytes are crucial, particularly during extreme temperatures; however, sweat rates can vary greatly between competitors. There is considerable evidence to support the use of sports drinks, gels and bars, as they are a convenient and portable source of carbohydrate that can be consumed during exercise, in training and in competition. Similarly, protein and amino acid supplements can be useful to help meet periods of increased protein requirements. Caffeine can be used as an ergogenic aid to help competitors stay awake during prolonged periods, enhance glycogen resynthesis and enhance endurance performance.

    Postoperative pulmonary complications (PPCs) are common after major non-thoracic surgery and associated with significant morbidity and high cost of care. A number of risk factors are strong predictors of PPCs. The overall goal of the preoperative pulmonary evaluation is to identify these potential, patient and procedure-related risks and optimize the health of the patients before surgery. A thorough clinical examination supported by appropriate laboratory tests will help guide the clinician to provide optimal perioperative care. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Major life changes are among factors that cause anxiety, and one of these changes is surgery. Emotional reactions to surgery have specific effects on the intensity and velocity as well as the process of physical disease. In addition, they can cause delay in patients recovery. This study is aimed at determining the relationship between religious beliefs and preoperative anxiety. Methods This survey is a correlational study to assess the relationship between religious beliefs and preoperative anxiety of patients undergoing abdominal, orthopaedic, and gynaecologic surgery in educational hospitals. We used the convenience sampling method. The data collection instruments included a questionnaire containing the Spielberger State-Trait Anxiety Inventory (STAI, and another questionnaire formulated by the researcher with queries on religious beliefs and demographic characteristics as well as disease-related information. Analysis of the data was carried out with SPSS software using descriptive and inferential statistics. Results were arranged in three tables. Results The findings showed that almost all the subjects had high level of religiosity and moderate level of anxiety. In addition, there was an inverse relationship between religiosity and intensity of anxiety, though this was not statistically significant. Conclusion The results of this study can be used as evidence for presenting religious counselling and spiritual interventions for individuals undergoing stress. Finally, based on the results of this study, the researcher suggested some recommendations for applying results and conducting further research.

Methods Patients with gastroesophageal (GE junction (Siewert type II and III or gastric adenocarcinoma who underwent neoadjuvant CRT followed by planned surgical resection at Duke University between 1987 and 2009 were reviewed. Overall survival (OS, local control (LC and disease-free survival (DFS were estimated using the Kaplan-Meier method. Toxicity was graded according to the Common Toxicity Criteria for Adverse Events version 4.0. Results Forty-eight patients were included. Most (73% had proximal (GE junction, cardia and fundus tumors. Median radiation therapy dose was 45 Gy. All patients received concurrent chemotherapy. Thirty-six patients (75% underwent surgery. Pathologic complete response and R0 resection rates were 19% and 86%, respectively. Thirty-day surgical mortality was 6%. At 42 months median follow-up, 3-year actuarial OS was 40%. For patients undergoing surgery, 3-year OS, LC and DFS were 50%, 73% and 41%, respectively. Conclusions Preoperative CRT for gastric cancer is well tolerated with acceptable rates of perioperative morbidity and mortality. In this patient cohort with primarily advanced disease, OS, LC and DFS rates in resected patients are comparable to similarly staged, adjuvantly treated patients in randomized trials. Further study comparing neoadjuvant CRT to standard treatment approaches for gastric cancer is indicated.

    During the last decades lung cancer is the leading cause of death worldwide for both sexes. Even though cigarette smoking has been proved to be the main causative factor, many other agents (e.g., occupational exposure to asbestos or heavy metals, indoor exposure to radon gas radiation, particulate air pollution) have been associated with its development. Recently screening programs proved to reduce mortality among heavy-smokers although establishment of such strategies in everyday clinical practice is much more difficult and unknown if it is cost effective compared to other neoplasms (e.g., breast or prostate cancer). Adding severe comorbidities (coronary heart disease, COPD) to the above reasons as cigarette smoking is a common causative factor, we could explain the low surgical resection rates (approximately 20-30%) for lung cancer patients. Three clinical guidelines reports of different associations have been published (American College of Chest Physisians, British Thoracic Society and European Respiratory Society/European Society of Thoracic Surgery) providing detailed algorithms for preoperative assessment. In the current mini review, we will comment on the preoperative evaluation of lung cancer patients. PMID:24672690

    To compare three anxiety scales; the anxiety visual analogue scale (VAS), the anxiety component of the Amsterdam preoperative anxiety and information scale (APAIS), and the state portion of the Spielburger state-trait anxiety inventory (STAI), for assessment of preoperative anxiety levels in same day admission patients. Patients completed the three anxiety assessment scales both before and after seeing the anesthesiologist preoperatively. The scales used were the STAI, the six-question APAIS, and the VAS. APAIS was further subdivided to assess anxiety about anesthesia (sum A), anxiety about surgery (sum S) and a combined anxiety total (i.e., sum C = sum A + sum S). These scales were compared to one another. Pearson's correlation (pair-wise deletion) was used for validity testing. Cronbach's alpha analysis was used to test internal validity of the various components of the APAIS scale. A correlation co-efficient (r) > or = 0.6 and P scale sets were completed by 197 patients. There was significant and positive correlation between VAS and STAI r = 0.64, P anxiety components of the APAIS (sum C) and desire for information were 0.84 and 0.77 respectively. In addition to VAS, the anxiety component of APAIS (sum C) is a promising new practical tool to assess preoperative patient anxiety levels.

Secondary aims include promoting school staff and parental support for heart health to help children achieve their goals and to provide experiential learning and service for MSU health profession students for academic credit. Methods/Design This pilot effectiveness study was approved by the MSU IRB. At the beginning and the end of the school year students undergo a CVD risk factor assessment conducted by MSU medical students and graduate students. Key intervention components include eight lesson plans (conducted bi-monthly designed to promote heart healthy nutrition and PA behaviors conducted by PE teachers with assistance from MSU undergraduate dietetic and kinesiology students

    Preoperative anxiety is a major problem in patients with brain tumors and is of high clinical relevance. However, to date no instruments have been validated for the assessment of preoperative anxiety for this patient group. The Amsterdam Preoperative Anxiety and Information Scale (APAIS) has shown promising results for the assessment of preoperative anxiety. The aim of this study was to determine its psychometric properties and the optimal cutoff score for patients with intracranial tumors to make it applicable in the neurosurgical setting. The sample totaled 180 neurosurgical patients with intracranial tumors. Patients were administered the APAIS along with the Hospital Anxiety and Depression Scale as the gold standard against which the APAIS was compared. Patients scoring 11 or above in the anxiety subscale of the Hospital Anxiety and Depression Scale were defined as clinical cases having anxiety. The psychometric properties of the APAIS were evaluated for a postulated 2-factor structure, Cronbach α, and correlations. The postulated 2-factor structure could not be replicated. Instead, we found a 3-factor solution (anxiety about the operation, anxiety about the anesthesia, information requirement). The area under the receiver operating characteristics curve ranged from ≥0.65 to ≥0.77. Optimal cutoff scores were calculated. The cutoff score for the anxiety scale was ≥10 for the whole sample and men only, and was ≥11 for women only. Analysis of the psychometric properties yielded satisfactory results (eg. Cronbach α for the anxiety scale >0.84). Despite its brevity, the APAIS is valid and recommendable for the assessment of preoperative anxiety in patients with intracranial tumors. As this is the first validation study focusing on patients with severe diseases and major surgeries, we recommend the application of our cutoff scores also for patients similar to our study population with regard to disease and surgery severity.

    The preferred treatment for lung cancer is surgery if the disease is considered resectable and the patient is considered surgically fit. Preoperative smoking cessation and/or preoperative pulmonary rehabilitation might improve postoperative outcomes after lung cancer surgery. The objectives of this systematic review were to determine the effectiveness of (1) preoperative smoking cessation and (2) preoperative pulmonary rehabilitation on peri- and postoperative outcomes in patients who undergo resection for lung cancer. We searched MEDLINE, PreMedline, Embase, Cochrane Library, Cinahl, BNI, Psychinfo, Amed, Web of Science (SCI and SSCI), and Biomed Central. Original studies published in English investigating the effect of preoperative smoking cessation or preoperative pulmonary rehabilitation on operative and longer-term outcomes in ≥ 50 patients who received surgery with curative intent for lung cancer were included. Of the 7 included studies that examined the effect of preoperative smoking cessation (n = 6) and preoperative pulmonary rehabilitation (n = 1) on outcomes after lung cancer surgery, none were randomized controlled trials and only 1 was prospective. The studies used different smoking classifications, the baseline characteristics differed between the study groups in some of the studies, and most had small sample sizes. No formal data synthesis was therefore possible. The included studies were marked by methodological limitations. On the basis of the reported bodies of evidence, it is not possible to make any firm conclusions about the effect of preoperative smoking cessation or of preoperative pulmonary rehabilitation on operative outcomes in patients undergoing surgery for lung cancer.

  18. Nutritional Aspects of Gastrointestinal Wound Healing

    Significance: Although the wound healing cascade is similar in many tissues, in the gastrointestinal tract mucosal healing is critical for processes such as inflammatory bowel disease and ulcers and healing of the mucosa, submucosa, and serosal layers is needed for surgical anastomoses and for enterocutaneous fistula. Failure of wound healing can result in complications including infection, prolonged hospitalization, critical illness, organ failure, readmission, new or worsening enterocutaneous fistula, and even death. Recent Advances: Recent advances are relevant for the role of specific micronutrients, such as vitamin D, trace elements, and the interplay between molecules with pro- and antioxidant properties. Our understanding of the role of other small molecules, genes, proteins, and macronutrients is also rapidly changing. Recent work has elucidated relationships between oxidative stress, nutritional supplementation, and glucose metabolism. Thresholds have also been established to define adequate preoperative nutritional status. Critical Issues: Further work is needed to establish standards and definitions for measuring the extent of wound healing, particularly for inflammatory bowel disease and ulcers. In addition, a mounting body of evidence has determined the need for adequate preoperative nutritional supplementation for elective surgical procedures. Future Directions: A large portion of current work is restricted to model systems in rodents. Therefore, additional clinical and translational research is needed in this area to promote gastrointestinal wound healing in humans, particularly those suffering from critical illness, patients with enterocutaneous fistula, inflammatory bowel disease, and ulcers, and those undergoing surgical procedures.

    Full Text Available Sunghye Kim,1 Amber K Brooks,2 Leanne Groban21Department of Hospital Medicine, 2Department of Anesthesiology, Wake Forest School of Medicine, Winston-Salem, NC, USAAbstract: Nearly 50% of Americans will have an operation after the age of 65 years. Traditional preoperative anesthesia consultations capture only some of the information needed to identify older patients (defined as ≥65 years of age undergoing elective surgery who are at increased risk for postoperative complications, prolonged hospital stays, and delayed or hampered functional recovery. As a catalyst to this review, we compared traditional risk scores (eg, cardiac-focused to geriatric-specific risk measures from two older female patients seen in our preoperative clinic who were scheduled for elective, robotic-assisted hysterectomies. Despite having a lower cardiac risk index and Charlson comorbidity score, the younger of the two patients presented with more subtle negative geriatric-specific risk predictors – including intermediate or pre-frail status, borderline malnutrition, and reduced functional/mobility – which may have contributed to her 1-day-longer length of stay and need for readmission. Adequate screening of physiologic and cognitive reserves in older patients scheduled for surgery could identify at-risk, vulnerable elders and enable proactive perioperative management strategies (eg, strength, balance, and mobility prehabilitation to reduce adverse postoperative outcomes and readmissions. Here, we describe our initial two cases and review the stress response to surgery and the impact of advanced age on this response as well as preoperative geriatric assessments, including frailty, nutrition, physical function, cognition, and mood state tests that may better predict postoperative outcomes in older adults. A brief overview of the literature on anesthetic techniques that may influence geriatric-related syndromes is also presented. Keywords: frailty, mobility

    Full Text Available Objectives: Preoperative chemotherapy plays a key role in management of bone sarcomas. Postoperative evaluation of histological necrosis has been the gold standard method of assessing response to preoperative chemotherapy. This study was done to evaluate the efficacy of static and dynamic magnetic resonance imaging (MRI for assessing response preoperatively. Materials and Methods: Our study included 14 patients (12 osteosarcomas and 2 malignant fibrous histiocytomas with mean age of 21.8 years, treated with preoperative chemotherapy followed by surgery. They were evaluated with static and dynamic MRI twice, before starting chemotherapy and again prior to surgery. Change in tumor volume and slope of signal intensity - time curve were calculated and correlated with percentage of histological necrosis using Pearson correlation test. Results: The change in dynamic MRI slope was significant (P = 0.001. Also, ≥60% reduction in slope of the curve proved to be an indicator of good histological response [positive predictive value (PPV =80%]. Change in tumor volume failed to show significant correlation (P = 0.071. Although it showed high negative predictive value (NPV = 85.7%, PPV was too low (PPV = 57.14%. Conclusions: Dynamic MRI correctly predicts histological necrosis after administration of preoperative chemotherapy to bone sarcomas. Hence, it can be used as a preoperative indicator of response to neoadjuvant chemotherapy. On the other hand, volumetric assessment by static MRI is not an effective predictor of histological necrosis. This study proves the superiority of dynamic contrast-enhanced study over volumetric study by MRI.

    The presence of gastrointestinal (GI) cancer and its treatment might aggravate patient nutritional status. Malnutrition is one of the major factors affecting the postoperative course. We evaluated changes in perioperative nutritional status and risk factors of postoperative severe malnutrition in the GI cancer patients. Nutritional status was prospectively evaluated using patient-generated subjective global assessment (PG-SGA) perioperatively between May and September 2011. A total of 435 patients were enrolled. Among them, 279 patients had been diagnosed with gastric cancer and 156 with colorectal cancer. Minimal invasive surgery was performed in 225 patients. PG-SGA score increased from 4.5 preoperatively to 10.6 postoperatively (pcancer patients, postoperative severe malnourishment increased significantly (p60, pcancer (pcancer, and open surgery remained significant as risk factors of severe malnutrition. The prevalence of severe malnutrition among GI cancer patients in this study increased from 2.3% preoperatively to 26.3% after an operation. Old age, preoperative weight loss, gastric cancer, and open surgery were shown to be risk factors of postoperative severe malnutrition. In patients at high risk of postoperative severe malnutrition, adequate nutritional support should be considered.

    Objective:To compare the arterial spin labeling and dynamic susceptibility contrast-enhanced MR imaging and explore the clinical application of arterial spin labeling (ASL) technique in the preoperation of tumor grade in brain gliomas. Methods: Twenty-three patients with gliomas ( all the cases were verified histologically, including 17 patients of highgrade gliomas, 6 patients of low-grade gliomas) were routinely examined by 3. 0 T MRI including ASL and DSC before operation. The maximal cerebral blood flow of solid regions of tumor (TBFmax) and the cerebral blood flow of opposite white matter, opposite grey matter and opposite hemisphere were measured on maps. Results: All of 23 cases demonstrated agreement between ASL and DSC MR imagings. The ratio of TBFmax/ opposite white matter CBF, TBFmax/opposite there was statistical difference between high-grade and low-grade gliomas. The threshold of TBFmax/opposite white matter CBF, TBFmax/opposite grey matter CBF, TBF max/opposite hemisphere CBF were 3. 06 , 0. 46 and 1. 31 respectively, the diagnosis sensibility were 100%, 88. 2% and lOO% respectively, and the specificity were 83. 3%, 83. 3% and 100 % respectively by ASL technique. Conclusion : The noninvasive and repcatable ASL technique was almost as sensitive as DSC MRI in detecting brain gliomas perfusing abnormaliries. It is helpful to give the grade of gliomas before operation.%目的:对照研究动脉自旋标记(arterial spin labeling,ASL)与动态磁敏感对比增强(dynamic susceptibility contrast-enhanced,DSC)灌注成像技术在脑胶质瘤中的灌注特点,探讨ASL在脑胶质瘤术前分级中的临床应用价值.方法:使用3.0T MR成像系统对23例脑胶质瘤患者(术后病理证实高级别胶质瘤17例,低级别胶质瘤6例)术前行常规扫描外,加扫ASL及DSC灌注检查,测量肿瘤实质部分最大肿瘤血流量(maximal tumor blood flow,TBFmax)以及对侧白质、对侧灰质、对侧半球的血流量(cerebral blood

    The causes of malnutrition in chronic terminal kidney failure are reviewed in the situation both before and after dialysis, as are the malnutrition rates in both circumstances and their treatment. Malnutrition has a high prevalence in terminal kidney patients, partly as a result of the therapeutic restriction on calories and proteins, but also due to the metabolic reactions typical of the disease and to anorexia. In patients subjected to dialytical methods, certain other mechanisms are added. In addition to malnutrition, there are alterations in the metabolism of calcium, phosphorus and potassium, as well as lipids, thus limiting nutritional therapy's ability to restore the nutritional status to normal. An awareness of energy expenditure in chronic terminal kidney failure and the consequences of malnutrition have led to new challenges in nutritional therapy, both in the dose and quality of the proteins, with a debate raging over the advantages of ketoanalogues, and also in the methods for providing nutrients. The ideal nutritional method for repletion is oral administration, but this can be enhanced with artificial support such as oral supplements, parenteral nutrition during dialysis or such alternatives as enteral nutrition at home in the case of chronic kidney problems in children, using percutaneous endoscopic gastrostomy (PEG), in order to nourish the patients and minimize growth disorders.

    The aim of this study was to evaluate the effect of dietician-delivered intensive nutritional support (INS) on postoperative outcome in patients with esophageal cancer. Approximately 50-80% of patients with esophageal cancer are malnourished at the time of diagnosis. Malnutrition enhances the risk of postoperative complications, resulting in delay of postoperative recovery and impairment of quality of life. Sixty-five patients with esophageal cancer were included. All patients who received surgery (n = 28) in the time frame between March 2009 and April 2010, the first year after the start of INS, were included in the INS intervention group. The control group (n = 37) consisted of patients who received surgery during the 3 years before the start of INS. Logistic regression analysis was used to compare differences in severity of postoperative complications using the Dindo classification. Linear regression was applied to evaluate differences in preoperative weight change. The adjusted odds ratio for developing serious complications after surgery of INS compared with the control group was 0.23 (95% confidence interval: 0.053-0.97; P = 0.045). Benefit was mainly observed in patients who received neoadjuvant therapy before esophagectomy (n = 35). The INS program furthermore resulted in a relative preoperative weight gain in comparison with the control group of +4.8% (P = 0.009, adjusted) in these neoadjuvant-treated patients. This study shows that dietician-delivered INS preserves preoperative weight and decreases severe postoperative complications in patients with esophageal cancer.

    To establish a preoperative decision model for accurate indication of systemic therapy in early-stage breast cancer using multiparametric MRI at 7-tesla field strength. Patients eligible for breast-conserving therapy were consecutively included. Patients underwent conventional diagnostic workup and one preoperative multiparametric 7-tesla breast MRI. The postoperative (gold standard) indication for systemic therapy was established from resected tumor and lymph-node tissue, based on 10-year risk-estimates of breast cancer mortality and relapse using Adjuvant! Online. Preoperative indication was estimated using similar guidelines, but from conventional diagnostic workup. Agreement was established between preoperative and postoperative indication, and MRI-characteristics used to improve agreement. MRI-characteristics included phospomonoester/phosphodiester (PME/PDE) ratio on 31-phosphorus spectroscopy (31P-MRS), apparent diffusion coefficients on diffusion-weighted imaging, and tumor size on dynamic contrast-enhanced (DCE)-MRI. A decision model was built to estimate the postoperative indication from preoperatively available data. We included 46 women (age: 43-74yrs) with 48 invasive carcinomas. Postoperatively, 20 patients (43%) had positive, and 26 patients (57%) negative indication for systemic therapy. Using conventional workup, positive preoperative indication agreed excellently with positive postoperative indication (N = 8/8; 100%). Negative preoperative indication was correct in only 26/38 (68%) patients. However, 31P-MRS score (p = 0.030) and tumor size (p = 0.002) were associated with the postoperative indication. The decision model shows that negative indication is correct in 21/22 (96%) patients when exempting tumors larger than 2.0cm on DCE-MRI or with PME>PDE ratios at 31P-MRS. Preoperatively, positive indication for systemic therapy is highly accurate. Negative indication is highly accurate (96%) for tumors sized ≤2,0cm on DCE-MRI and with PME

  7. Nutrition and parasite interaction.

    This overview focuses on the interaction between nutritional status and gastrointestinal nematode infection in ruminants and considers: (i) the influence of the parasite on host metabolism; and (ii) the effect of host nutrition on the establishment and survival of parasite populations, the development of the host-immune response and the pathophysiology of infection. Gastrointestinal nematodes reduce voluntary feed intake and efficiency of feed utilisation, a key feature being an increased endogenous loss of protein into the gastrointestinal tract. Overall there is movement of protein from productive processes into repair of the gastrointestinal tract, synthesis of plasma proteins and mucoprotein production. Although reduction in feed intake is a major factor contributing to the reduced performance of parasitised ruminants, the underlying mechanisms of the anorexia are poorly understood. Supplementation of the diet with additional protein does not appear to affect initial establishment of nematode infections but the pathophysiological consequences are generally more severe on lower planes of protein nutrition. The main effect of protein supplementation is to increase the rate of acquisition of immunity and increase resistance to reinfection and this has been associated with an enhanced cellular immune response in the gastrointestinal mucosa. The unresponsiveness of the young lamb can be improved by dietary protein supplementation. Recent trials have shown that growing sheep offered a free choice between a low and a high protein ration are able to modify their diet selection in order to alleviate the increase in protein requirements which result from gastrointestinal nematode infection. Studies on the influence of nutrition on the expression of genotype have shown that the benefits of a superior genotype are not lost on a low protein diet whereas a high protein diet can partially emeliorate the disadvantages of an inferior genotype. In addition to dietary protein

    Murkin, Claire Elizabeth

    Theatre nurses use antiseptic skin preparation products every day, but little thought seems to be given as to why a surgeon has a particular preference for one antiseptic skin preparation over another - whether it is for its efficacy, safety or application properties. Woodhead et al (2004) states that nurses still work in a ritualistic environment. Rituals are 'any action performed according to custom, without understanding the reasons why it is being practised'. Nursing practice should be evidence-based; nurses should understand the rationale behind the choice of a particular antiseptic, and be knowledgable about the clinical effectiveness of antiseptic's use pre-operatively, to achieve optimum results. This article focuses on the main types of antiseptic skin preparation while highlighting each product's activity and the relevant considerations for choosing the appropriate product for each patient. Theatre staff need to emphasize the importance of skin preparation and the correct application techniques, while educating the scrub team and surgeons with respect to skin preparation.

    This study aimed to identify factors contributing to anxiety at induction of anaesthesia in children. One hundred and twenty children aged five to twelve years and scheduled for surgery requiring general anaesthesia were included. Children were interviewed and assessed prior to surgery. Parents completed anxiety measures prior to surgery and were interviewed after the induction of anaesthesia. The level of children's anxiety was determined at the time of induction of anaesthesia by the modified Yale Preoperative Anxiety Scale. Factors associated with increased levels of anxiety in the children included increased number of people in the room at induction of anaesthesia; longer waiting time between admission at the hospital and induction of anaesthesia; negative memories of previous hospital experiences; and having a mother who does not practise a religion. Suggestions for implementation of the findings and for future research are provided.

    2012-02-01

    AIMS AND OBJECTIVES: To identify the information needs of children undergoing tonsillectomy with reference to content of information, method of delivery, information providers and timing of information provision. BACKGROUND: Tonsillectomy can be anxiety provoking for children and preoperative preparation programmes are long recognised to reduce anxiety. However, few have been designed from the perspectives of children and to date little is known about how best to prepare children in terms of what to tell them, how to convey information to them, who can best provide information and what is the best timing for information provision. DESIGN: A qualitative descriptive study. METHOD: Data were collected from nine children (aged 6-9) using interviews supported by a write and draw technique. Data were coded and categorised into themes reflecting content, method, providers and timing of information. RESULTS: Children openly communicated their information needs especially on what to tell them to expect when facing a tonsillectomy. Their principal concerns were about operation procedures, experiencing \\'soreness\\' and discomfort postoperatively and parental presence. Mothers were viewed as best situated to provide them with information. Children were uncertain about what method of information and timing would be most helpful to them. CONCLUSION: Preoperative educational interventions need to take account of children\\'s information needs so that they are prepared for surgery in ways that are meaningful and relevant to them. Future research is needed in this area. RELEVANCE TO CLINICAL PRACTICE: Practical steps towards informing children about having a tonsillectomy include asking them what they need to know and addressing their queries accordingly. Child-centred information leaflets using a question and answer format could also be helpful to children.

  16. Geriatric nutrition.

    Markham, R W; Hodgkins, E M

    1989-01-01

    In recent decades, veterinary medicine has become more successful in prolonging the healthy, useful lives of pets. As a result, the practitioner spends a greater part of each practice day caring for the geriatric animal, both healthy and unhealthy. Because of their longevity, older pets are typically regular family members, with owners who seek the finest health care possible for their pets. The practice of geriatric medicine most properly should begin not when the dog or cat reaches some specific "golden" age, but rather when the wiggly, robust puppy or kitten receives its first examination. Like all parts of a sound preventive program, geriatric nutrition best follows from a well-considered juvenile and adult nutrition program. Furthermore, once it becomes senior, the "well" geriatric is as much a candidate for a diet designed especially to accommodate old age changes as is his unhealthy contemporary. In fact, evidence suggests that appropriate dietary management of the healthy, but often subclinical, patient may help postpone the signs of dysfunction and increase quality and length of life. A knowledge of the most significant nutrients and the impact of each on aging systems is now, and will become increasingly more, important to the progressive, skillful veterinarian.

  17. How to ensure nutrition security in the global economic crisis to protect and enhance development of young children and our common future.

    The global economic crisis, commodity price hikes, and climate change have worsened the position of the poorest and most vulnerable people. These crises are compromising the diet and health of up to 80% of the population in most developing countries and threaten the development of almost an entire generation of children ( approximately 250 million), because the period from conception until 24 mo of age irreversibly shapes people's health and intellectual ability. High food prices reduce diversity and nutritional quality of the diet and for many also reduce food quantity. Poor households are hit hardest, because they already spend 50-80% of expenditures on food, little on medicines, education, transport, or cooking fuel, and cannot afford to pay more. Reduced public spending, declining incomes, increased food and fuel prices, and reduced remittance thus impede and reverse progress made toward Millenium Development Goals 1, 4, and 5. Investments in nutrition are among the most cost-effective development interventions because of very high benefit:cost ratios, for individuals and for sustainable growth of countries, because they protect health, prevent disability, boost economic productivity, and save lives. To bridge the gap between nutrient requirements, particularly for groups with high needs, and the realistic dietary intake under the prevailing circumstances, the use of complementary food supplements to increase a meal's nutrient content is recommended. This can be in the form of, e.g., micronutrient powder or low-dose lipid-based nutrient supplements, which can be provided for free, in return for vouchers, at subsidized, or at commercial prices.

    The beneficial effects of lung volume reduction surgery (LVRS) on patients with severe chronic obstructive pulmonary disease (COPD) on pulmonary function and exercise performance has been established. However, the impact on nutritional status and prognosis has not been demonstrated. In the present study, we investigated the changes in nutritional status in COPD patients undergoing bilateral thoracoscopic LVRS and also analyzed the relationship between nutritional status and postoperative complications and prognosis. After LVRS, body weight, fat-free mass (FFM) and caloric intake were significantly increased. Increase in FFM correlated significantly with improvement in exercise performance. In underweight patients before LVRS, the incidence of post-operative complications was significantly higher than in normal-weight patients, and a patient who was moderately-to-severely underweight (% ideal body weight nutritional status after LVRS contributes to improvement in exercise performance, and that preoperative nutritional status has a significant impact on postoperative morbidity and mortality. From our data, we concluded that preoperative nutritional assessment is an important part of the preoperative evaluation of LVRS, and that LVRS provides nutritional benefits for underweight patients with severe COPD.

    To determine whether poor nutritional status can predict postoperative delirium in elderly adults undergoing hip fracture surgery. Prospective observational cohort study. Italian orthogeriatric unit. Individuals aged 70 and older (mean age 84.0 ± 6.6, 74.5% female) consecutively admitted for surgical repair of a proximal femur fracture between September 2012 and April 2016 (N = 415). Participants underwent a comprehensive geriatric assessment including nutritional status, which was evaluated using the Mini Nutritional Assessment Short Form (MNA-SF). The MNA-SF-based three-class stratification was tested using multivariable logistic regression to assess its role in predicting postoperative delirium (outcome). Seventy-eight malnourished individuals (MNA-SF score 0-7), 185 at risk of malnutrition (MNA-SF score 8-11), and 152 who were well nourished (MNA-SF score 12-14) were compared. On average, individuals with poor nutritional status were more disabled and more cognitively impaired than those who were well nourished and those at risk of malnutrition. Moreover, those who were malnourished were more likely to have postoperative delirium. Multivariate regression analysis adjusted for age, sex, comorbidity, functional impairment, preoperative cognitive status, and American Society of Anesthesiologists score showed that those who were at risk of malnutrition (odds ratio (OR) = 2.42, 95% confidence interval (CI) = 1.29-4.53) and those who were overtly malnourished (OR = 2.98, 95% CI = 1.43-6.19) were more likely to develop postoperative delirium. This is the first study in a Western population showing that risk of malnutrition and overt malnutrition, as assessed using the MNA-SF, are independent predictors of postoperative delirium. Accordingly, nutritional status should be assessed in individuals with hip fracture before surgery to determine risk of developing delirium. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Medical information is mandatory before any medical procedure, including pediatric anesthesia. Preoperative information covers many aspects, including medico-psychologic and judicial aspects. When the patient is a child, information must be delivered to the parents in priority. However, the French law has given a particular attention to the opinion of the child. In 70% of the cases, preoperative anxiety of the parents is more related to anesthesia than to the surgical procedure itself. We have to explain the most frequent adverse effects, as well as the more severe and well known complications to the parents, even though they are very infrequent. The only cases where preoperative information is not required are: emergency cases and refusal of the patient or the parents to be informed. While information is necessarily oral, it may be completed using a written document. The quality of the preoperative information directly influences the quality of the psychological preoperative preparation of the parents, and thereafter of the child. Preoperative preparation programs have been developed, but controversial results have been observed. The great majority of the studies on preoperative programs were performed in the USA, where the demand for preoperative information is very important. It is far from sure that the results of all these studies may be extrapolated to French parents, and French studies are needed.

    Prevention of preoperative anxiety with anxiolytic premedication is associated with improved preoperative outcomes in surgical patients. The objective of the authors\\' study was to evaluate the percentage of surgical patients that are prescribed premedication for preoperative anxiety before their anticipated surgical procedure. A prospective study was carried out by theatre nursing staff in the theatre reception bay of a university teaching hospital. A questionnaire was designed to record the number of patients that described symptoms consistent with preoperative anxiety. The number of patients that had been offered anxiolytic premedication for preoperative anxiety was also recorded. Consent was obtained from 115 consecutive surgical patients (male, n=52; female, n=63). Of these, 66% (n=76) reported anxiety before their surgical procedure (male: n=27, female: n=49). Premedication with a low-dose benzodiazepine was prescribed by an anaesthetist in 4% of cases (n=5). Patients that received premedication preoperatively reported effective relief of their anxiety symptoms This study demonstrates that preoperative patient anxiety is highly prevalent. The authors\\' findings suggest that premedication with anxiolytic pharmacological therapy may be an underused therapeutic resource for managing preoperative patient anxiety.

    The aims of the study were to summarize the characteristics of the spinal epidural cavernous hemangioma, especially for the MRI, and to improve the accurate rate of the preoperative diagnosis. The clinical and medical imaging data of six patients with pure spinal epidural cavernous hemangioma proved by operation and pathology were analyzed retrospectively. The level was thoracic (n = 2), thoracolumbar (n = 1), lumbar (n = 1), and sacral (n = 2). The tumor showed lobulated contour, and the areas the tumors appeared were dorsal side of spinal cord (n = 2), ventral side (n = 1), and lateral side (n = 3). In all six patients, the lesions were isointense to the spinal cord on T{sub 1}-weighted images and hyperintense on T{sub 2}-weighted images and showed homogeneously strong enhancement on contrast-enhanced T{sub 1}-weighted images. The characteristic MRI features were named as the ''wafting-silk'' sign. Widening of the intervertebral neural foramen (n = 4) and erosion of the adjacent bones (n = 3) can be observed. MRI of the epidural cavernous hemangioma showed the characteristic lobulated contour, which encircled the spinal cord. T{sub 1}WI on the MRI presented as isointense and T{sub 2}WI presented as hyperintense and a homogeneously strong enhancement, so we first proposed the sign of wafting silk. The widening of the intervertebral neural foramen and erosion of the adjacent bones can easily be observed. MR imaging has an important role in the detection and diagnosis of pure spinal epidural cavernous hemangioma. (orig.)

    Preoperative anxiety, as an emotional reaction, is common among patients undergoing surgery. The purpose of this study was to examine the effect of acupressure on preoperative anxiety before abdominal surgery. The 70 subjects of this clinical trial were randomly assigned into the acupressure group (n=35), which received acupressure at the true points, or the placebo group (n=35), which received acupressure at sham (false) points. Preoperative anxiety and vital signs before and after the intervention were measured in both groups. The findings demonstrated a reduction in the level of preoperative anxiety for both groups (Pacupressure group (Pacupressure at true points (third eye and Shen men) can reduce higher preoperative anxiety of patients before abdominal surgery and that it has had a more clinically beneficial effect than sham points.

    Upland rice (Oryza sativa L.) is a major crop of Eastern India grown during the wet season (June/July to September/October). Aerobic soils of the upland rice system, which are acidic and inherently phosphorus (P) limiting, support native arbuscular mycorrhizal (AM) activity. Attempts were made to improve P nutrition of upland rice by exploiting this natural situation through different crop rotations and application of AM fungal (AMF) inoculum. The effect of a 2-year crop rotation of maize (Zea mays L.) followed by horse gram (Dolichos biflorus L.) in the first year and upland rice in the second year on native AM activity was compared to three existing systems, with and without application of a soil-root-based inoculum. Integration of AM fungal inoculation with the maize-horse gram rotation had synergistic/additive effects in terms of AMF colonization (+22.7 to +42.7%), plant P acquisition (+11.2 to +23.7%), and grain yield of rice variety Vandana (+25.7 to +34.3%).

    Lactic acid bacteria were isolated and identified from quinoa flour, spontaneously fermented quinoa dough, and type I quinoa sourdough. Strains were further selected based on acidification and proteolytic activities. Selected Lactobacillus plantarum T6B10 and Lactobacillus rossiae T0A16 were used as mixed starter to get quinoa sourdough. Compared to non-fermented flour, organic acids, free amino acids, soluble fibers, total phenols, phytase and antioxidant activities, and in vitro protein digestibility markedly increased during fermentation. A wheat bread was made using 20% (w/w) of quinoa sourdough, and compared to baker's yeast wheat breads manufactured with or without quinoa flour. The use of quinoa sourdough improved the chemical, textural, and sensory features of wheat bread, showing better performances compared to the use of quinoa flour. Protein digestibility and quality, and the rate of starch hydrolysis were also nutritional features that markedly improved using quinoa sourdough as an ingredient. This study exploited the potential of quinoa flour through sourdough fermentation. A number of advantages encouraged the manufacture of novel and healthy leavened baked goods.

    During the past decades, encouraging progress has been made in the prevention of surgical site infections (SSI). However, as SSI still occur today, strategic prevention measures such as standardized skin antisepsis must be implemented and rigorously promoted. Recent discoveries in skin physiology necessitate the development of novel antiseptic agents and procedures in order to ameliorate their efficacy. In particular, alternate target structures in the skin need to be taken into consideration for the development of the next generation of antiseptics. Recent investigations have shown that a high number of microorganisms are located within and in the close vicinity of the hair follicles. This suggests that these structures are an important reservoir of bacterial growth and activity in human skin. To date, it has not been fully elucidated to what extent conventional liquid antiseptics sufficiently target the hair follicle-related microbial population. Modern technologies such as tissue-tolerable plasma (TTP) have been tested for their potential antiseptic efficiency by reducing the bacterial load in the skin and in the hair follicles. First experiments using liposomes to deliver antiseptics into the hair follicles have been evaluated for their potential clinical application. The present review evaluates these two innovative methods for their efficacy and applicability in preoperative skin antiseptics.

    Full Text Available Henry T Zhan,1 Seth T Purcell,1,2 Ruth L Bush1 1Texas A&M Health Science Center College of Medicine, Bryan, 2Baylor Scott and White, Temple, TX, USA Abstract: It is well known that patients who suffer from peripheral (noncardiac vascular disease often have coexisting atherosclerotic diseases of the heart. This may leave the patients susceptible to major adverse cardiac events, including death, myocardial infarction, unstable angina, and pulmonary edema, during the perioperative time period, in addition to the many other complications they may sustain as they undergo vascular surgery procedures, regardless of whether the procedure is performed as an open or endovascular modality. As these patients are at particularly high risk, up to 16% in published studies, for postoperative cardiac complications, many proposals and algorithms for perioperative optimization have been suggested and studied in the literature. Moreover, in patients with recent coronary stents, the risk of noncardiac surgery on adverse cardiac events is incremental in the first 6 months following stent implantation. Just as postoperative management of patients is vital to the outcome of a patient, preoperative assessment and optimization may reduce, and possibly completely alleviate, the risks of major postoperative complications, as well as assist in the decision-making process regarding the appropriate surgical and anesthetic management. This review article addresses several tools and therapies that treating physicians may employ to medically optimize a patient before they undergo noncardiac vascular surgery.

An overview of the Nutrition Care Process model and the application of nutrition guidelines based on literature, reports, documents and programmes of international health, food and physical activity authorities was done. Results. The Nutrition Care Process model requires registered dieticians, standardized terminology as well as nutrition diagnosis categorization. It consists of four distinct, but interrelated and connected steps: (a nutrition assessment, (b nutrition diagnosis, (c nutrition intervention, and (d nutrition monitoring and evaluation. An individual approach is essential for successful medical nutrition therapy. Nutrition guidelines facilitate the process of understanding and application of medical nutrition therapy. Conclusion. The Nutrition Care process provides dietetic professionals information on high-quality client nutrition care. The success of medical nutrition therapy rests not only upon the advice of the dietician, but also upon the client’s compliance.

    The purpose of this study is to examine orbital lesions identified on preoperative radiologic imaging as cavernous venous malformations (CVMs), identify their imaging characteristics, and determine if these may help differentiate CVMs from other intraorbital masses. An IRB-approved retrospective chart review over 30 years was undertaken identifying lesions "consistent with cavernous hemangioma" on radiologic studies, which were subsequently surgically resected with a tissue diagnosis. All radiologic images (CT and MRI) obtained preoperatively were re-reviewed by a single masked neuroradiologist. The pattern of contrast enhancement on sequential MRI views was used to determine whether the enhancing characteristics helped identify CVMs compared to other intraorbital masses. Fifty-seven orbital lesions consistent with a CVM were identified on imaging. Fourteen (25%) of them were resected, of which nine (64%) were found to be CVMs on pathologic examination. Five (36%) were found to be a different lesion, most commonly schwannoma (21%). On imaging, CVMs tended to display heterogeneous progressive enhancement, whereas other tumors, in particular schwannomas, enhanced at their maximum level immediately. Based on these characteristics, on re-review, the masked neuroradiologist was able to differentiate a CVM versus other tumors for all 14 imaging cases. This study suggests that examining the pattern of contrast enhancement may help to correctly differentiate a CVM from other isolated, encapsulated orbital lesions on CT/MR imaging.

    To test whether a combined intervention of art therapy and clown visits could enhance the efficacy of oral medication in reducing children's anxiety at parental separation prior to induction of anaesthesia. Approximately 50% of children undergoing surgery report high anxiety at anaesthesia induction. Complementary therapies have been used to decrease children's anxiety, but no study has evaluated the efficacy of a combination of such therapies. This is an observational study, which involved allocating different interventions to two groups and measuring their anxiety at two time points. This study assigned 78 children (aged 3-11 years) undergoing general anaesthesia for surgery to two conditions. The control group underwent general anaesthesia following standard practice, and the intervention group received an intervention of integrated art therapy and clown visits upon their arrival at the hospital and throughout their time in the preoperating room. Each child in both groups received 0·5 mg/kg oral midazolam 30 minutes before surgery and had a parent present throughout their time in the preoperating room. Each child's anxiety was evaluated twice using the Modified Yale Preoperative Anxiety Scale: at baseline and at separation from parents. Repeated measures anova was used to test for differences between the time points and the two groups. Children in the intervention group showed a significant (p art therapy and clown visits enhanced the effect of midazolam in reducing children's anxiety at preoperative separation from parents.

    The Codex Alimentarius is a collection of internationally recognized standards, codes of practice, guidelines, and other recommendations relating to foods, food production, and food safety. Among other functions, it is responsible for setting international standards for safety and hygiene. Codex food standards and guidelines directed at foods produced primarily for young infants and children have important implications for maintaining nutritional status and health, especially given the positioning of these products as components of established World Health Organization (WHO)/UNICEF-recommended feeding strategies. Recently, new products targeted at this age group (e.g., lipid-based nutrient supplements and micronutrient powders) have been produced and used, but these are not totally covered under existing Codex guidelines or standards. The objective of this paper is to review the role of the Codex process and specifically to suggest revisions to existing Codex guidelines on formulated complementary foods (Guidelines for Formulated Supplementary Foods for Older Infants and Young Children, CAC/GL 08-1991) to encompass this new category of fortified complementary foods and home fortificants. In reviewing the existing guidelines, potential areas for revision included the sections on the recommended nutrients in these foods and their intended use. Updating the Codex guidelines provides the opportunity to encourage production and use of new products for children and help ensure that such foods, when used as directed, do not interfere with breastfeeding. The revised guidelines would help governments develop national regulations covering all forms of formulated complementary foods. They would also lessen impediments to international trade by providing clear guidance for foods used in feeding programs and for young children, particularly in developing countries.

  18. Recognition and management of preoperative risk.

    Science.gov (United States)

    Nierman, E; Zakrzewski, K

    1999-08-01

    Internists are frequently asked to do preoperative consultations and to manage perioperative complications. Realistic goals are to identify patient factors that increase the risk of surgery, to quantify this risk in order to make decisions about the appropriateness of and timing of the surgery, to provide recommendations on how to minimize the risk, to identify and manage coexisting medical conditions and their associated medication requirements, to monitor the patient for perioperative problems, and to make recommendations to deal with these problems when they occur. With few exceptions, nonselective imaging and laboratory screening tests have repeatedly been shown to be of little value when the history and physical do not suggest a problem. The risk associated with the planned surgery can be estimated, with the most common serious complications being cardiac events. Updated versions of Goldman's risk indices are particularly helpful for this. Clinical variables are optimally combined with selective stress testing to discern which patients will benefit from preoperative revascularization. This has been studied best in the setting of vascular surgery. A critical guiding principle is that the value of revascularization must be judged in terms of long term gains rather than just immediate perioperative benefit. Other interventions include the selective use of beta blockers, adequate analgesia for all, control of hypertension, and appropriate volume management, especially in the settings of preexisting CHF or valvular disease. It must also be recognized that perioperative ischemia and CHF often present atypically. An approach that combines aspects of both the ACC/AHA and the ACP guidelines seems optimal. A variety of noncardiac issues must also be addressed. Postoperative pulmonary complications are common, especially with preexisting pulmonary disease, thoracic and upper abdominal surgery, and obesity. PFTs and ABGs are indicated in selected patients.

    Routine ordering of pre-operative investigations yields a low true positive rate and is not cost effective. In this study, case notes of 251 adults who underwent elective surgery were reviewed. Pre-operative investigations were classified as 'indicated' or 'not indicated', based on the national guidelines. Only 56% of all tests done were indicated. The overall rates of expected and unexpected abnormal values from pre-operative blood investigations were 51.1% and 34.4% respectively. This study found that selective testing based on guidelines was beneficial. However, the results also suggest that the local guidelines need to be reviewed.

    Full Text Available Abstract Background To identify preoperative, perioperative and postoperative risk factors that influence the success of pterygium surgery. Methods This is a prospective study of thirty-six patients with primary or recurrent pterygia. A detailed anamnesis and an ophthalmological examination were performed looking for the following factors: age, race, latitude and altitude of the main place of residence, hours of exposure to the sun, use of protective measures against UV-radiation, classification of pterygium, width of the pterygium at limbus, surgical technique (conjunctival autograft plus suturing versus tissue glue, graft alterations (misapposition, granuloma, haemorrhage, oedema, retraction or necrosis, and postoperative symptoms (foreign-body sensation, pain. The examinations were performed 2 and 7 days and 2, 6 and 12 months after surgery. In addition, recurrence was defined as any growth of conjunctiva into the cornea. Results A logistic regression and a survival analysis have been used to perform data analysis. A total number of 36 patients completed a one year follow-up. A total of 13 patients were born and lived in Spain, and 26 came from other countries, mostly Latin America. A total number of 8 males (no women presented a recurrence, mainly between 2 and 6 months. The hours of sun exposure through their life was independently related to surgical success. Pterygia of less than 5 mm of base width showed a weak positive correlation with recurrence. None of the other factors considered were significantly related to recurrence. Conclusions Male gender and high sun exposure are strongly and independently related to surgical success after the removal of pterygia.

    To describe the conjunctival bacterial spectrum of our patients undergoing intraocular surgery and their antibiotic sensitivity during the study period. A retrospective study of preoperative conjunctival culture of patients consecutively scheduled for intraocular surgery from 21 February 2011 to 1 April 2013. Specimens were directly seeded onto blood-agar and MacConkey-agar (aerobiosis incubation, 2 days), and on chocolate-agar (6% CO2 incubation, 7 days). The identified bacteria were divided into 3 groups according to their origin; the bacteria susceptibility tests were performed on those more pathogenic and on some of the less pathogenic when more than 5 colonies were isolated. The sensitivity of the exigent growing bacteria was obtained with disk diffusion technique, and for of the non-exigent bacteria by determining their minimum inhibitory concentration. The Epidat 3.1 program was used for statistical calculations. A total of 13,203 bacteria were identified in 6,051 cultures, with 88.7% being typical colonizers of conjunctiva (group 1), 8.8% typical of airways (group 2), and the remaining 2.5% of undetermined origin (group 3). 530 cultures (8.8%) were sterile. The sensitivity of group 1 was: 99% vancomycin, 95% rifampicin, 87% chloramphenicol, 76% tetracycline. Levels of co-trimoxazole, aminoglycosides, quinolones, β-lactams and macrolides decreased since 2007. The group 2 was very sensitive to chloramphenicol, cefuroxime, rifampicin, ciprofloxacin and amoxicillin/clavulanate. In group 3, to levofloxacin 93%, ciprofloxacin 89%, tobramycin 76%, but ceftazidime 53% and cefuroxime 29% decreased. None of the tested antibiotics could eradicate all possible conjunctival bacteria. Bacteria living permanently on the conjunctiva (group 1) have achieved higher resistance than the eventual colonizers. Copyright © 2013 Sociedad Española de Oftalmología.

    Nearly 50% of Americans will have an operation after the age of 65 years. Traditional preoperative anesthesia consultations capture only some of the information needed to identify older patients (defined as ≥65 years of age) undergoing elective surgery who are at increased risk for postoperative complications, prolonged hospital stays, and delayed or hampered functional recovery. As a catalyst to this review, we compared traditional risk scores (eg, cardiac-focused) to geriatric-specific risk measures from two older female patients seen in our preoperative clinic who were scheduled for elective, robotic-assisted hysterectomies. Despite having a lower cardiac risk index and Charlson comorbidity score, the younger of the two patients presented with more subtle negative geriatric-specific risk predictors - including intermediate or pre-frail status, borderline malnutrition, and reduced functional/mobility - which may have contributed to her 1-day-longer length of stay and need for readmission. Adequate screening of physiologic and cognitive reserves in older patients scheduled for surgery could identify at-risk, vulnerable elders and enable proactive perioperative management strategies (eg, strength, balance, and mobility prehabilitation) to reduce adverse postoperative outcomes and readmissions. Here, we describe our initial two cases and review the stress response to surgery and the impact of advanced age on this response as well as preoperative geriatric assessments, including frailty, nutrition, physical function, cognition, and mood state tests that may better predict postoperative outcomes in older adults. A brief overview of the literature on anesthetic techniques that may influence geriatric-related syndromes is also presented.

    Team sports are based on intermittent high-intensity activity patterns, but the exact characteristics vary between and within codes, and from one game to the next. Despite the challenge of predicting exact game demands, performance in team sports is often dependent on nutritional factors. Chronic issues include achieving ideal levels of muscle mass and body fat, and supporting the nutrient needs of the training program. Acute issues, both for training and in games, include strategies that allow the player to be well fuelled and hydrated over the duration of exercise. Each player should develop a plan of consuming fluid and carbohydrate according to the needs of their activity patterns, within the breaks that are provided in their sport. In seasonal fixtures, competition varies from a weekly game in some codes to 2-3 games over a weekend road trip in others, and a tournament fixture usually involves 1-3 days between matches. Recovery between events is a major priority, involving rehydration, refuelling and repair/adaptation activities. Some sports supplements may be of value to the team athlete. Sports drinks, gels and liquid meals may be valuable in allowing nutritional goals to be met, while caffeine, creatine and buffering agents may directly enhance performance.

    A model for multicultural nutrition counseling competencies for registered dietitians was developed and tested. Six hundred four registered dietitians who were members of The American Dietetic Association Public Health Nutrition Practice Group or directors of dietetic internships and didactic programs in dietetics were selected by a stratified random sample method and were mailed a survey. Respondents rated each of 46 competencies using a Likert scale to delineate how essential each competency will be for entry-level dietitians in the next 10 years. Of the 60% who responded (n=363), 94.4% met the study selection criteria. Most were white (85.7%), spoke English as their primary language (96.8%), and had a master's degree (64.4%). Many (37.9%) worked in community/public health facilities or organizations, and 50.4% provided nutrition counseling or education to clients culturally different from themselves. Exploratory principal components analysis extracted 3 factors with 28 competencies loading on them: multicultural nutrition counseling skills, multicultural awareness, and multicultural food and nutrition knowledge. Subjects responded similarly whether or not they provided nutrition counseling to culturally different clients. Secondary analysis revealed no significant interaction or differences between how bilingual dietitians and those of color scored items in the 3 factors. The resulting model is a guideline that can be used by educators to enhance dietetics education and training and by public health nutritionists as a basis for self-evaluation and selection of continuing education opportunities to enhance their multicultural nutrition counseling competence.

    Assessing outcomes and the impact from behavioral nutrition interventions has remained challenging because of the lack of methods available beyond traditional nutrition assessment tools and techniques. With the current high global obesity and related chronic disease rates, novel methods to evaluate the impact of behavioral nutrition-based interventions are much needed. The objective of this narrative review is to describe and review the current status of knowledge as it relates to 4 different innovative methods or tools to assess behavioral nutrition interventions. Methods reviewed include 1) the assessment of stress and stress responsiveness to enhance the evaluation of nutrition interventions, 2) eye-tracking technology in nutritional interventions, 3) smartphone biosensors to assess nutrition and health-related outcomes, and 4) skin carotenoid measurements to assess fruit and vegetable intake. Specifically, the novel use of functional magnetic resonance imaging, by characterizing the brain's responsiveness to an intervention, can help researchers develop programs with greater efficacy. Similarly, if eye-tracking technology can enable researchers to get a better sense as to how participants view materials, the materials may be better tailored to create an optimal impact. The latter 2 techniques reviewed, smartphone biosensors and methods to detect skin carotenoids, can provide the research community with portable, effective, nonbiased ways to assess dietary intake and quality and more in the field. The information gained from using these types of methodologies can improve the efficacy and assessment of behavior-based nutrition interventions.

    Few supplement combinations that are marketed to athletes are supported by scientific evidence of their effectiveness. Quite often, under the rigor of scientific investigation, the patented combination fails to provide any greater benefit than a group given the active (generic) ingredient. The focus of this chapter is supplement combinations and dosing strategies that are effective at promoting an acute physiological response that may improve/enhance exercise performance or influence chronic adaptations desired from training. In recent years, there has been a particular focus on two nutritional ergogenic aids—creatine monohydrate and protein/amino acids—in combination with specific nutrients in an effort to augment or add to their already established independent ergogenic effects. These combinations and others are discussed in this chapter.

    Full Text Available Perioperative management of pancreatic and periampullary cancer poses a considerable challenge to the pancreatic surgeon, anesthesiologist, and the intensive care team. The preoperative surgical evaluation of a pancreatic lesion aims to define the nature of the lesion (malignant or benign, stage the tumor, and to determine resectability or other non-surgical treatment options. Patients are often elderly and may have significant comorbidities and malnutrition. Obstructive jaundice may lead to coagulopathy, infection, renal dysfunction, and adverse outcomes. Routine preoperative biliary drainage can result in higher complication rates, and metal stents may be preferred over plastic stents in selected patients with resectable disease. Judicious use of antibiotics and maintaining fluid volume preoperatively can reduce the incidence of infection and renal dysfunction, respectively. Perioperative fluid therapy with hemodynamic optimization using minimally invasive monitoring may help improve outcomes. Careful patient selection, appropriate preoperative evaluation and optimization can greatly contribute to a favorable outcome after major pancreatic resections.

    One of the clearest indications for enteral nutrition is made up by patients who underwent treatment for orofacial pathology. In this way, we have reviewed retrospectively, 321 clinical histories of patients who underwent treatment (orofacial surgery), dividing these according to the pathology; neoplasia or non-neoplasia (173/148), with enteral nutrition 24 hours after the intervention. Data are collected with regard to the tolerance (vomiting, diarrhea), time needed to reach 1.500 kcal/day, need of parenteral nutritional support, transferrin, prealbumin, and albumin quantification at the start of the nutritional therapy, as well as the total duration there of. Globally, the good enteric tolerance of both groups of patients is noted, despite the fact that the oncological group showed a greater degree of protein malnutrition (statistically significant). As for the total duration of the nutrition, this is greater in the neoplasias, probably due to a more aggressive surgery. The results obtained permit modification of the basic enteral nutrition protocol (reduction of the time used to reach the maximum volume), as well as stressing the preoperative and postoperative regulated nutritional evaluation.

    Neonates undergoing noncardiac surgery are at risk for adverse outcomes. Preoperative anemia is a strong independent risk factor for postoperative mortality in adults. To our knowledge, this association has not been investigated in the neonatal population. To assess the association between preoperative anemia and postoperative mortality in neonates undergoing noncardiac surgery in a large sample of US hospitals. Using data from the 2012 and 2013 pediatric databases of the American College of Surgeons National Surgical Quality Improvement Program, we conducted a retrospective study of neonates undergoing noncardiac surgery. Analysis of the data took place between June 2015 and December 2015. All neonates (0-30 days old) with a recorded preoperative hematocrit value were included. Anemia defined as hematocrit level of less than 40%. Receiver operating characteristics analysis was used to assess the association between preoperative hematocrit and mortality, and the Youden J Index was used to determine the specific hematocrit cutoff point to define anemia in the neonatal population. Demographic and postoperative outcomes variables were compared between anemic and nonanemic neonates. Univariate and multivariable logistic regression analyses were used to determine factors associated with postoperative neonatal mortality. An external validation was performed using the 2014 American College of Surgeons National Surgical Quality Improvement Program database. Neonates accounted for 2764 children (6%) in the 2012-2013 American College of Surgeons National Surgical Quality Improvement Program databases. Neonates inlcuded in the study were predominately male (64.5%), white (66.3%), and term (69.9% greater than 36 weeks' gestation) and weighed more than 2 kg (85.0%). Postoperative in-hospital mortality was 3.4% in neonates and 0.6% in all age groups (0-18 years). A preoperative hematocrit level of less than 40% was the optimal cutoff (Youden) to predict in-hospital mortality

    A femoral neck fracture in an elderly patient often represents a major challenge for the orthopaedic surgeon who has to face not only the fracture, but also all the multiple issues related to age. Among others, malnutrition has been recognised as an important factor associated with severe aggravation in these patients. One-hundred-and-forty-seven patients were enrolled to investigate the use of two markers of patient nutritional status, i.e. serum albumin level and total leukocyte count (TLC), as predictors of mortality in the elderly patient suffering from proximal femur fracture. We found that low preoperative values of serum albumin and TLC proved to be directly related to worse outcomes. Therefore, these exams can be useful to identify patients with a femoral neck fracture that have higher risk of malnutrition and consequent higher mortality and that can benefit from some measures, such as albumin or protein nutritional supplement.

    Preoperative planning enables an assessment of the size of the implants needed before total hip replacement. Eggli and Müller demonstrated the reproduciblity of preoperative planning but did not evaluate its contribution to reducing limb length discrepancy. As femur lateralization and the position of the prosthetic center of rotation affect joint mechanics, it would be useful to assess their contribution to the efficacy of preoperative planning. We reviewed the files of 57 patients who underwent total hip arthroplasty for primary joint degeneration or necrosis limited to one hip. The healthy hip served as a control. The surgical plan was elaborated from the preoperative pelvis x-rays (AP and lateral views) and anatomic measurements on films obtained three months postoperatively. In 49 cases, preoperative planning predicted a restoration of the normal anatomy of the operated hip (center of rotation, femur lateralization, length of the operated limb). This objective was achieved in only 22.5% of the cases. Femur lateralization was the most difficult objective to achieve (59.2%). Equal limb length and good position of the center of rotation was achieved in 70% of the cases. For eight patients (14%) preoperative planning was not satisfactory, the implant offset not being adapted to the patient's anatomy. There are limits to preoperative planning, particularly for restitution of adequate femur lateralization. This difficulty appears to be related to three factors: inadequate adaptation of the implant to hip anatomy (14% of the cases in our experience), stiff rotation in degenerative hips inhibiting proper assessment of the length of the femoral neck, and relative imprecision of operative evaluation of femoral anteversion affecting femur lateralization and the level of the femoral cut. Although imperfect, preoperative planning is, in our opinion, essential before total hip arthroplasty in order to avoid major positioning errors and operative difficulties.

    OBJECTIVE To observe the effect of preoperative chemoradiotherapy for inflammatory breast cancer.METHODS From December 1996 to December 2000, we received and treated 21 patients with inflammatory breast carcinoma with a combinedmodality treatment. The chemotherapy protocol consisted of cyclophosphamide (CTX), pirarubicin (THP-ADM) and 5-fluorouracil (5-FU) or CTX, 5-Fu and methotrexate (MTX). The same infusion scheme was repeated on day 21. After 3~4 cycles the patients were treated with radiotherapy. When the radiation dose reached 40 Gy, the patients who were unable or unwilling to under go an operation received continued radiotherapy. When the radiation dose to the supra clavicular fossa and internal mammary lymph nodes reached 60 Gy and 50 Gy respectively, the radiotherapy was stopped. Chemotherapy was then continued with the original scheme. Patients who had indications for surgery and were willing to under go an operation received no treatment for 2 weeks, after which a total mastectomy was performed. Chemotherapy and radiotherapy was resumed with the original scheme after the operations. When the radiation dose reached 50 Gy, radiotherapy was stopped.RESULTS All patients were followed-up for more than 5 years with a follow-up rate of 100%. The overall 3 and 5-year survival rates of these patients were 42.9%, and 23.8% respectively. For patients in Stage ⅢB the 3 and 5-year survival rates were 50.0% and 27.8% respectively, and for patients in Stage Ⅳ, the 3 and 5-year survival rates were both 0.0%.There was a significant difference between the 2 stage groups (P<0.05,X2=11.60). For patients who received an operation, the 3 and 5-year survival rates were 80.0% and 33.3% respectively, For patients who were not treated with an operation, the 3 and 5-year survival rates were both0.0%, There was a significant difference between the operated and nonoperated groups (P<0.05, X2=11.64).CONCLUSION The prognosis of inflammatory breast carcinoma is poor

    Full Text Available Background Nutrition can be regarded as an important part of any preparation program, as well as an important part of life. It seems essential to develop nutritional science and improve eating habits with the purpose of developing a healthy diet and avoiding the outcomes that arise from a lack of nutrition. Proper nutrition is one of the important factors for the development of health. Lack of sufficient awareness about nutrition can result in improper eating habits. Objectives The present study evaluated the effect of knowledge about healthy nutrition and nutrition science on the knowledge development approach. Materials and Methods In this cross-sectional descriptive study, the statistical population consisted of 190 experts and other scholars in the area of nutritional science. A questionnaire based on demographic details, nutritional science, nutrition education, research, proper solutions to individuals’ nutritional problems, and a culture of nutrition was used for data collection. Results A relatively strong positive correlation was found between the knowledge development approach, nutritional science, nutrition education and research, and proper solutions for individual nutritional problems and a culture of nutrition (P < 0.001. Conclusions 1 Effective enhancement and participation in an academic community will be important in the future of food and nutrition security; however, major gaps and weaknesses also exist in this context; 2 The main weaknesses in relation to the lack of clear policies and procedures include focusing on only Tehran, Iran; the need to overcome bureaucracy; and problems related to motivation, capital, and international communications; 3 Qualitative and quantitative improvement of research is not possible without access to skilled experts and researchers; 4 To solve these problems, it will be beneficial to pay more attention to the role of universities, facilitate intellectual communication among professors in

    This symposium was organized to bring insights from the social sciences into the awareness of nutrition scientists committed to developing and implementing effective nutrition interventions internationally. The symposium explored three different areas in the field where a more precise analysis of culture could enhance the effectiveness of nutrition science: 1) in the implementation of nutrition science research in the field; 2) in the collaboration of multiple stakeholders working to enhance nutrition in a national setting; and 3) in the language and discussions used to frame proposed changes in large scale food and nutrition security policy transnationally. Three social scientists, Monique Centrone Stefani, Lucy Jarosz, and David Pelletier were invited to share insights from their respective disciplines and respondents from within the field of nutrition provided initial reflections to better understand such perspectives. The symposium's interdisciplinary nature was designed to illustrate the challenge of multiple perspectives and methodologies and to advance understanding that could derive from such an exchange for those in the field of international nutrition seeking to decrease global hunger and malnutrition.

    The number of total hip arthroplasties is continuously rising. Although less invasive surgical techniques, sophisticated component design, and intraoperative navigation techniques have been introduced, the rate of peri- and postoperative complications, including dislocations, fractures, nerve palsies, and infections, is still a major clinical problem. Better patient outcome, faster recovery and rehabilitation, and shorter operation times therefore remain to be accomplished. A promising strategy is to use minimally invasive techniques in conjunction with modular implants, aimed at independently reconstructing femoral offset and leg length on the basis of highly accurate preoperative planning. Plain radiographs have clear limitations for the correct estimation of hip joint geometry and bone quality. Three-dimensional assessment based on computed tomography (CT) allows optimizing the choice and positions of implants and anticipating difficulties to be encountered during surgery. Postoperative CT is used to monitor operative translation and plays a role in arthroplastic quality management. Radiologists should be familiar with the needs of orthopedic surgeons in terms of CT acquisition, post-processing, and data transfer. The CT protocol should be optimized to enhance image quality and reduce radiation exposure. When dedicated orthopedic CT protocols and state-of-the-art scanner hardware are used, radiation exposure can be decreased to a level just marginally higher than that of conventional preoperative radiography. Surgeons and radiologists should use similar terminology to avoid misunderstanding and inaccuracies in the transfer of preoperative planning. (orig.)

    The progression from standard celluloid films to digitalized technology led to the development of new software programs to fulfill the needs of preoperative planning. We describe here preoperative digitalized programs and the variety of conditions for which those programs can be used to facilitate preparation for surgery. A PubMed search using the keywords "digitalized software programs," "preoperative planning" and "total joint arthroplasty" was performed for all studies regarding preoperative planning of orthopedic procedures that were published from 1989 to 2014 in English. Digitalized software programs are enabled to import and export all picture archiving communication system (PACS) files (i.e., X-rays, computerized tomograms, magnetic resonance images) from either the local working station or from any remote PACS. Two-dimension (2D) and 3D CT scans were found to be reliable tools with a high preoperative predicting accuracy for implants. The short learning curve, user-friendly features, accurate prediction of implant size, decreased implant stocks and low-cost maintenance makes digitalized software programs an attractive tool in preoperative planning of total joint replacement, fracture fixation, limb deformity repair and pediatric skeletal disorders.

    We describe a series of 14 surgical blister aneurysm (BA) patients and compare outcomes in those with known cerebral BA to those lacking preoperative BA diagnosis/recognition. BA are broad, fragile, pathologic dilatations of the intracranial arteries. They have a low prevalence but are associated with substantially higher surgical morbidity and mortality rates than saccular aneurysms. A confirmed, preoperative BA diagnosis can alter operative management and technique. We performed a retrospective review of prospectively collected data on aneurysm patients undergoing surgery at a major academic institution. All patients from 1990 to 2011 with a postoperative BA diagnosis were included. Chart reviews were performed to identify patients with preoperative BA diagnoses and collect descriptive data. We identified 14 patients, 12 of whom presented with subarachnoid hemorrhage. The age of the cohort (mean ± standard deviation: 41.8 ± 13.9 years) was lower than that generally reported for saccular aneurysm populations. Preoperatively diagnosed BA had an intraoperative rupture (IOR) rate of 28.6% (2/7) compared to a 57.1% (4/7) rate in the undiagnosed patients. The mortality rate in the preoperatively diagnosed cohort was 14.3% (1/7) while that of the undiagnosed group was 42.8% (3/7). BA remain a diagnostic and treatment challenge with morbidity and mortality rates exceeding those of saccular aneurysms. Preoperative BA diagnosis may decrease IOR and mortality rates and improve patient outcomes.

    The aim of the study was to evaluate the effects of preoperative fasting and fluid limitation in patients undergoing laparoscopic cholecystectomy. Although traditional long-term fasting is not recommended in current preoperative guidelines, this is still a common intervention. Visual analogue scale was used to assess hunger, thirst, sleepiness, exhaustion, nausea and pain; State and Trait Anxiety Inventory was used to assess the preoperative anxiety of 99 patients undergoing elective laparoscopic cholecystectomy. Mean time of preoperative fasting and fluid limitation were, respectively, 14.70 ± 3.14 and 11.25 ± 3.74 h. Preoperatively, 58.60% of the patients experienced moderate anxiety. Patients fasting 12 h or longer had higher hunger, thirst, nausea and pain scores. The mean trait anxiety score of patients fasting 12 h or longer was statistically significantly higher. Receiving nothing by mouth after midnight preoperatively is a persisted intervention and results in discomfort of patients. Clinical protocols should be revised and nurses should be trained in current fasting protocols. © 2014 Wiley Publishing Asia Pty Ltd.

    Inflammatory bowel disease (IBD) is a group of chronic, lifelong, and relapsing illnesses, such as ulcerative colitis and Crohn's disease, which involve the gastrointestinal tract. There is no cure for these diseases, but combined pharmacological and nutritional therapy can induce remission and maintain clinical remission. Malnutrition and nutritional deficiencies among IBD patients result in poor clinical outcomes such as growth failure, reduced response to pharmacotherapy, increased risk for sepsis, and mortality. The aim of this review is to highlight the consequences of malnutrition in the management of IBD and describe nutritional interventions to facilitate induction of remission as well as maintenance; we will also discuss alternative delivery methods to improve nutritional status preoperatively.

  13. Nutrition for the pediatric surgical patient: approach in the peri-operative period

    Directory of Open Access Journals (Sweden)

    Full Text Available Nutrition is essential for maintenance of physiologic homeostasis and growth. Hypermetabolic states lead to a depletion of body stores, with decreased immunocompetence and increased morbidity and mortality. The purpose of this paper is to provide an update regarding the provision of appropriate nutrition for the pediatric surgical patient, emphasizing the preoperative and postoperative periods. Modern nutritional support for the surgical patient comprises numerous stages, including assessment of nutritional status, nutritional requirements, and nutritional therapy. Nutritional assessment is performed utilizing the clinical history, clinical examination, anthropometry, and biochemical evaluation. Anthropometric parameters include body weight, height, arm and head circumference, and skinfold thickness measurements. The biochemical evaluation is conducted using determinations of plasma levels of proteins, including album, pre-albumin, transferrin, and retinol-binding protein. These parameters are subject to error and are influenced by the rapid changes in body composition in the peri-operative period. Nutritional therapy includes enteral and/or parenteral nutrition. Enteral feeding is the first choice for nutritional therapy. If enteral feeding is not indicated, parenteral nutrition must be utilized. In all cases, an individualized, adequate diet (enteral formula or parenteral solution is obligatory to decrease the occurrence of overfeeding and its undesirable consequences.

    Preoperative short-course radiotherapy with immediate surgery improves local control in patients with rectal cancer. Tumor responses are smaller than those described with radiochemotherapy. Preliminary data associate this lower response to the short period until surgery. The aim of this study is to analyze the response to preoperative short-course radiotherapy and its correlation with the interval to surgery especially analyzing patients with mesorectal fascia involvement. A total of 155 patients with locally advanced rectal cancer treated with preoperative radiotherapy (5×5Gy) were retrospectively analyzed. Tumor response in terms of rates of complete pathological response, downstaging, tumor regression grading and status of the circumferential resection margin were quantified. The mean interval from radiotherapy to surgery was 23 days. The rate of complete pathological response was 2.2% and 28% experienced downstaging (stage decreased). No differences between these rates and interval to surgery were detected. Eighty-eight patients had magnetic resonance imaging for staging (in 31 patients the mesorectal fascia was involved).The mean time to surgery in patients with involvement of the fascia and R0 surgery was 27 days and 16 days if R1 (P=.016). The cutoff of 20 days reached the highest probability of achieving a free circumferential resection margin between patients with mesorectal fascia involvement, with no statistically significant differences: RR 3.036 95% CI=(0.691-13.328), P=.06. After preoperative short-course radiotherapy, an interval>20 days enhances the likelihood of achieving a free circumferential resection margin in patients with mesorectal fascia involvement.

  5. Enhanced recovery after vascular surgery: protocol for a systematic review

    Directory of Open Access Journals (Sweden)

    Gotlib Conn Lesley

    2012-11-01

    Full Text Available Abstract Background The enhanced recovery after surgery (ERAS programme is a multimodal evidence-based approach to surgical care which begins in the preoperative setting and extends through to patient discharge in the postoperative period. The primary components of ERAS include the introduction of preoperative patient education; reduction in perioperative use of nasogastric tubes and drains; the use of multimodal analgesia; goal-directed fluid management; early removal of Foley catheter; early mobilization, and early oral nutrition. The ERAS approach has gradually evolved to become the standard of care in colorectal surgery and is presently being used in other specialty areas such as vascular surgery. Currently there is little evidence available for the implementation of ERAS in this field. We plan to conduct a systematic review of this literature with a view to incorporating ERAS principles into the management of major elective vascular surgery procedures. Methods We will search EMBASE (OVID, 1947 to June 2012, Medline (OVID, 1948 to June 2012, and Cochrane Central Register of Controlled Trials (Wiley, Issue 1, 2012. Searches will be performed with no year or language restrictions. For inclusion, studies must look at adult patients over 18 years. Major elective vascular surgery includes carotid, bypass, aneurysm and amputation procedures. Studies must have evaluated usual care against an ERAS intervention in the preoperative, perioperative or postoperative period of care. Primary outcome measures are length of stay, decreased complication rate, and patient satisfaction or expectations. Only randomized controlled trials will be included. Discussion Most ERAS approaches have been considered in the context of colorectal surgery. Given the increasing use of multiple yet different aspects of this pathway in vascular surgery, it is timely to systematically review the evidence for their independent or combined outcomes, with a view to implementing

  6. An anaesthetic pre-operative assessment clinic reduces pre-operative inpatient stay in patients requiring major vascular surgery.

    LENUS (Irish Health Repository)

    O'Connor, D B

    2012-02-01

    BACKGROUND: Patients undergoing major vascular surgery (MVS) require extensive anaesthetic assessment. This can require extended pre-operative stays. AIMS: We investigated whether a newly established anaesthetic pre-operative assessment clinic (PAC) would reduce the pre-operative inpatient stay, avoid unnecessary investigations and facilitate day before surgery (DBS) admissions for patients undergoing MVS. PATIENT AND METHODS: One year following and preceding the establishment of the PAC the records of patients undergoing open or endovascular aortic aneurysm repair, carotid endarterectomy and infra-inguinal bypass were reviewed to measure pre-operative length of stay (LoS). RESULTS: Pre-operative LoS was significantly reduced in the study period (1.85 vs. 4.2 days, respectively, P < 0.0001). Only 12 out of 61 patients in 2007 were admitted on the DBS and this increased to 33 out of 63 patients (P = 0.0002). No procedure was cancelled for medical reasons. CONCLUSION: The PAC has facilitated accurate outpatient anaesthetic assessment for patients requiring MVS. The pre-operative in-patient stay has been significantly reduced.

    To investigate the prognostic significance of preoperative fibrinogen levels in colon cancer patients. A total of 255 colon cancer patients treated at the Affiliated Tumor Hospital of Xinjiang Medical University from June 1(st) 2005 to June 1(st) 2008 were enrolled in the study. All patients received radical surgery as their primary treatment method. Preoperative fibrinogen was detected by the Clauss method, and all patients were followed up after surgery. Preoperative fibrinogen measurements were correlated with a number of clinicopathological parameters using the Student t test and analysis of variance. Survival analyses were performed by the Kaplan-Meier method and Cox regression modeling to measure 5-year disease-free survival (DFS) and overall survival (OS). The mean preoperative fibrinogen concentration of all colon cancer patients was 3.17 ± 0.88 g/L. Statistically significant differences were found between preoperative fibrinogen levels and the clinicopathological parameters of age, smoking status, tumor size, tumor location, tumor-node-metastasis (TNM) stage, modified Glasgow prognostic scores (mGPS), white blood cell (WBC) count, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and carcinoembryonic antigen (CEA) levels. Univariate survival analysis showed that TNM stage, tumor cell differentiation grade, vascular invasion, mGPS score, preoperative fibrinogen, WBC, NLR, PLR and CEA all correlated with both OS and DFS. Alpha-fetoprotein (AFP) and body mass index correlated only with OS. Kaplan-Meier analysis revealed that both OS and DFS of the total cohort, as well as of the stage II and III patients, were higher in the hypofibrinogen group compared to the hyperfibrinogen group (all P TNM stage, mGPS score, CEA, and AFP levels correlated with both OS and DFS. Preoperative fibrinogen levels can serve as an independent prognostic marker to evaluate patient response to colon cancer treatment.

  13. Preoperative psychological testing--another form of prejudice.

    2008-10-01

    Preoperative psychological screening of bariatric surgery candidates has become routine, and a significant proportion of patients have their surgery deferred as a consequence. If psychological testing is being used as a form of preoperative triage, both patients and surgeons are entitled to know whether there is sufficient evidence to justify its use in this way. We define the argument for psychological screening as consisting of four premises (p1-p4) and a conclusion (C) as follows: (p1) A significant minority of obese patients will not be successful in losing weight following bariatric surgery-the "failure" group; (p2) A significant minority of patients will exhibit abnormal psychological profiles during preoperative testing; (p3) The majority of individuals referred to in (p2) will be found in group (p1) i.e., abnormal psychological profiles identified preoperatively predict less favorable weight loss outcomes postoperatively; (p4) Identifying patients with adverse psychological profiles preoperatively would allow either exclusion of those at high risk of failure or provide a more secure rationale for targeted pre- and postoperative support; (C) Psychological screening should be part of the routine preoperative assessment for patients undergoing obesity surgery. We reviewed the literature to find evidence to support the premises and show that (p1) can be justified but that (p2) is problematic and can only be accepted in a heavily qualified version. We find no evidence for (p3) and since (p4) and (C) are predicated on (p3), the argument clearly fails. There is no evidence to suggest that preoperative psychological screening can predict postoperative outcomes and no justification for using such testing as a means of discriminating between candidates presenting themselves for bariatric surgery.

  14. To See or Not to See: Do Front of Pack Nutrition Labels Affect Attention to Overall Nutrition Information?

    Directory of Open Access Journals (Sweden)

    Laura Bix

    Full Text Available Front of pack (FOP nutrition labels are concise labels located on the front of food packages that provide truncated nutrition information. These labels are rapidly gaining prominence worldwide, presumably because they attract attention and their simplified formats enable rapid comparisons of nutritional value.Eye tracking was conducted as US consumers interacted with actual packages with and without FOP labels to (1 assess if the presence of an FOP label increases attention to nutrition information when viewers are not specifically tasked with nutrition-related goals; and (2 study the effect of FOP presence on consumer use of more comprehensive, traditional nutrition information presented in the Nutritional Facts Panel (NFP, a mandatory label for most packaged foods in the US.Our results indicate that colored FOP labels enhanced the probability that any nutrition information was attended, and resulted in faster detection and longer viewing of nutrition information. However, for cereal packages, these benefits were at the expense of attention to the more comprehensive NFP. Our results are consistent with a potential short cut effect of FOP labels, such that if an FOP was present, participants spent less time attending the more comprehensive NFP. For crackers, FOP labels increased time spent attending to nutrition information, but we found no evidence that their presence reduced the time spent on the nutrition information in the NFP.The finding that FOP labels increased attention to overall nutrition information by people who did not have an explicit nutritional goal suggests that these labels may have an advantage in conveying nutrition information to a wide segment of the population. However, for some food types this benefit may come with a short-cut effect; that is, decreased attention to more comprehensive nutrition information. These results have implications for policy and warrant further research into the mechanisms by which FOP labels

    Both malnutrition and obesity are related to worsened post-operative outcomes after colorectal surgery. Obese cancer patients may be malnourished as a result of short-term weight loss. The present study aimed to evaluate preoperative nutritional status, body composition and dietary intake related to post-operative complications (POC) and post-operative hospital days (POHD) in elective colorectal cancer (CRC) patients. Anthropometry, body composition measured by bioelectric spectroscopy and dietary habits assessed by a validated food-frequency questionnaire were examined in 100 newly-diagnosed CRC patients. Data from 30-day POC and POHD were collected from medical records. Nonparametric and chi-squared tests and logistic regression were used to analyse associations between body and dietary variables and post-operative outcome. Twenty-nine patients had at least one POC. The median POHD was six. Body size and composition measures and short-term weight loss were no different between patients with and without POC, or between patients with POHD composition and short-term weight loss were not related to 30-day post-operative outcomes in CRC patients. A high content of marine n-3 PUFA in preoperative habitual diets may protect against POC after CRC surgery. © 2012 The Authors Journal of Human Nutrition and Dietetics © 2012 The British Dietetic Association Ltd.

  19. Should patients with cancer be offered nutritional support: does the benefit outweigh the burden?

    Science.gov (United States)

    Koretz, Ronald L

    2007-05-01

    Nutrition support has been widely advocated as adjunctive therapy for a variety of underlying illnesses, including surgery and medical oncotherapy (radiation or chemotherapy for cancer). Both parenteral and enteral nutrition have been mistakenly viewed as feeding, when, in fact, they are medical interventions with associated risks and costs. The argument that nutrition support has to be provided to patients to prevent 'starving to death' confuses the difference between dying in a malnourished state and dying as a direct consequence of nutrient deprivation; cancer patients fit into the former category. As is true for any other medical intervention, efficacy is best established by randomized controlled clinical trials. When these forms of nutrition support have been so assessed, they have not usually been found to be any more efficacious than food on a tray or intravenous 5% dextrose solutions. In fact, parenteral nutrition actually caused harm in patients receiving medical oncotherapy (more total and infectious complications and fewer tumor responses). With regard to cancer patients, the only benefit that was demonstrated was the use of preoperative parenteral nutrition in patients undergoing attempted curative surgery for cancer of the upper gastrointestinal tract (esophagus, stomach, or pancreas). As nutrition support has associated complications (infections, mechanical problems with the tubes, and metabolic problems from the infusates) as well as costs, it cannot be recommended for cancer patients with the exception of the preoperative care of those with upper gastrointestinal malignancies and the occasional patient with gastrointestinal tract inadequacy owing to a slow-growing lesion.

  20. Nutrition education: linking research, theory, and practice.

    Science.gov (United States)

    Contento, Isobel R

    2008-01-01

    The increase in obesity and chronic diseases such as diabetes and heart disease worldwide reflects the complex interactions of biology, personal behaviour and environment. Consequently there has been a greater recognition of the importance of nutrition education. An analysis of the evidence from 300+ studies shows that nutrition education is more likely to be effective when it focuses on behaviour/ action (rather than knowledge only) and systematically links theory, research and practice. There are three essential components to nutrition education: 1. A motivational component, where the goal is to increase awareness and enhance motivation by addressing beliefs, attitudes through effective communication strategies. 2. An action component, where the goal is to facilitate people's ability to take action through goal setting and cognitive self-regulation skills. 3. An environmental component, where nutrition educators work with policymakers and others to promote environmental supports for action. Each component needs to be based on appropriate theory and research. The procedure for program design can use the logic model: Inputs are the resources needed as well as the needs analysis process. The outputs are the activities within the three components of nutrition education described above. Here the behavioural focus is selected and theory and research are used to design appropriate educational strategies to achieve the targeted behaviours. The outcomes are the short, medium or long-term impacts of the nutrition program. These are evaluated through the use of appropriate designs and instruments. Nutrition education programs that link research, theory, and practice are more likely to be effective.

    Unrelieved postoperative pain may impair rehabilitation, compromise functional outcomes, and lead to patient dissatisfaction. Preemptive multimodal analgesic techniques may improve outcomes after surgery. We hypothesized that patients using preoperative cryotherapy plus a standardized postoperative treatment plan will have lower pain scores and require less pain medication compared with patients receiving a standardized postoperative treatment plan alone after arthroscopically assisted anterior cruciate ligament reconstruction (ACLR). A total of 53 consecutive patients undergoing arthroscopically assisted ACLR performed by one of seven surgeons were randomly assigned to one of two groups. Group 1 received no preoperative cryotherapy and group 2 received 30 to 90 minutes of preoperative cryotherapy to the operative leg using a commercial noncompressive cryotherapy unit. Visual analog scale pain scores and narcotic use were recorded for the first 4 days postoperatively. Total hours of cold therapy and continuous passive motion (CPM) use and highest degree of flexion achieved were recorded as well. Group 1 consisted of 26 patients (15 allograft Achilles tendon and 11 autograft bone patellar tendon bone [BPTB]), and group 2 consisted of 27 patients (16 allograft Achilles tendon and 11 autograft BPTB). Group 2 patients reported less pain (average 1.3 units, p cryotherapy, hours of CPM use, or maximum knee flexion achieved. Complications did not occur in either group. This is the first report we are aware of showing the postoperative effects of preoperative cryotherapy. Our results support the safety and efficacy of preoperative cryotherapy in a multimodal pain regimen for patients undergoing ACL reconstruction.

    Thrombocytosis, which is defined as a platelet count greater than 400 platelets/nl, has been found to be an independent predictor of shorter survival in various tumors. Release of growth factors from tumors has been proposed to increase platelet counts. Preoperative platelet counts and other clinical and hematological parameters were reviewed from the records of 153 patients diagnosed between 1999 and 2004 with histologically confirmed glioblastoma in order to evaluate the prognostic significance of preoperative thrombocytosis in these patients. The relationship between thrombocytosis and survival was initially analyzed in all patients regardless of further therapy. Univariate log-rank tests showed that the median survival time of 29 patients with preoperative thrombocytosis (19%) was significantly shorter (4 months; 95% confidence interval [95% CI], 3–6 months) compared to 124 patients with normal platelet counts (11 months; 95% CI, 8–13 months; p = 0.0006). Multivariate analysis (Cox proportional hazards model) confirmed preoperative platelet count, age, prothrombin time, and activated partial thromboplastin time to be prognostic factors of survival (all p thrombocytosis was diagnosed (6 months; 95% CI, 4–12 months) compared to patients with normal platelet count (13 months; 95% CI, 11–15 months; p = 0.0359). In multivariate analysis, age, platelet count, preoperative prothrombin time, and degree of tumor resection retained significance as prognostic factors of survival (all p thrombocytosis to be a prognostic factor associated with shorter survival time in patients with glioblastoma.

Aim: To study the incidence of preoperative thrombocytosis (platelets greater than 400x10 in epithelial ovarian cancer and its association with other clinicopathologic factors. Materials and Methods: Sixty-five patients with invasive ovarian epithelial cancer were retrospectively reviewed and analyzed for the association preoperative thrombocytosis with other clinical and histopathological prognostic factors. Means were analyzed by Student′s t test; proportions were determined by Chi-square analysis. Results: Twenty of 65 (37.5% patients had thrombocytosis at primary diagnosis. Patients with preoperative thrombocytosis were found to have lower hemoglobin (P < 0.0002, more advanced stage disease (P < 0.05 and higher grade tumors (P < 0.02. Patients with thrombocytosis had greater likelihood of subpotimal cytoreduction. Conclusions: Preoperative thrombocytosis is a frequent finding in ovarian carcinomas and their association with advanced stage disease and higher grade denotes that platelets play a role in the tumor growth and progression.

    As part of an ongoing theme in our laboratory on reducing morbidity during minimally-invasive intracardiac procedures, we developed a computer-assisted intervention system that provides safe access inside the beating heart and sufficient visualization to deliver therapy to intracardiac targets while maintaining the efficacy of the procedure. Integrating pre-operative information, 2D trans-esophageal ultrasound for real-time intra-operative imaging, and surgical tool tracking using the NDI Aurora magnetic tracking system in an augmented virtual environment, our system allows the surgeons to navigate instruments inside the heart in spite of the lack of direct target visualization. This work focuses on further enhancing intracardiac visualization and navigation by supplying the surgeons with detailed 3D dynamic cardiac models constructed from high-resolution pre-operative MR data and overlaid onto the intra-operative imaging environment. Here we report our experience during an in vivo porcine study. A feature-based registration technique previously explored and validated in our laboratory was employed for the pre-operative to intra-operative mapping. This registration method is suitable for in vivo interventional applications as it involves the selection of easily identifiable landmarks, while ensuring a good alignment of the pre-operative and intra-operative surgical targets. The resulting augmented reality environment fuses the pre-operative cardiac model with the intra-operative real-time US images with approximately 5 mm accuracy for structures located in the vicinity of the valvular region. Therefore, we strongly believe that our augmented virtual environment significantly enhances intracardiac navigation of surgical instruments, while on-target detailed manipulations are performed under real-time US guidance.

    Full Text Available Good nutrition is the foundation for good health. While basic nutritional assessment is part of many medical consultations, it remains underutilized despite becoming increasingly recognized as important for chronic disease prevention and management. Many studies identify shortfalls in physicians’ knowledge and attitudes toward nutrition as a result of inadequate emphasis in medical school. Additional teaching about nutrition and nutritional assessment procedures was integrated within a first year module of a MBBS program. Blended learning techniques were employed to facilitate student engagement and sessions were evaluated via student response system technology (clickers or minute paper feedback. The initial survey to all medical students (n=1037 documented that less than half (45% felt they could discuss nutrition with patients. The majority (n=606 regularly consulted the internet for nutrition information, while only 163 utilised peer-reviewed journals. With the first year cohort (n=297 “clickers” revealed that 91% felt nutrition important to health care and 82% felt it important in general practice. 71% found using clickers an interesting enhancement, whilst 70% noted the nutrition content informative. Early nutrition teaching was well received by students. Long-term increases in nutritional information dissemination, particularly by influential health care workers, might benefit not only economies but also the health of society as a whole.

    Full Text Available Introduction: Decades of research support the theory that when there are sports competitions the question of what to eat and drink in order to enhance sport performance. Nutrition is one of the most important factors in achieving top performance athletes. According to most studies conducted in the world's top athletes receive information from their coaches when it comes to sports nutrition, especially of the coaches involved in fitness training. (Burns, Schiller, Merrick & Wolf, 2004.The aim of this study was to determine the knowledge of sports nutrition in sports coaching. Mthods: The sample was composed of 30 licensed coaches from Montenegro (football, handball, basketball, volleyball, athletics and tennis. Knowledge of sports nutrition was tested by means of a standardized questionnaire. The questionnaire was designed to determine the knowledge manager on sports nutrition, the ingredients that are necessary in order to provide a sufficient amount of energy to training and competition, the dietary supplements, meal prior to the competition as well as dehydration and rehydration during training and competition. The survey was anonymous. The data were analyzed by statistical methods, using the statistical software STATISTICA for WINDOWS. Results: According to the results as a whole, it can be concluded that the trainer's knowledge of sports nutrition at a satisfactory level. Out of 600 responses was achieved 469 correct answers, or 78.1%. However, when looking at individual responses then satisfaction with the relative high percentage loss since the observed large gaps on very important issues related to sports nutrition. Discussion: By analyzing and comparing research results (Matkovic, Prince & Cigrovski, 2006 that in a sample of 56 coaches basketball and skiing, received 77.8% of correct answers and insight into the results of our study, it is clear that the results of the approximate value of both work, which is an indicator of quality

    AIM: To investigate the role of preoperative biliary drainage (PBD) in the outcome of classical pancreaticodu odenectomy.METHODS: A 10-year retrospective data analysis was performed on patients (n = 48) undergoing pancreaticoduodenectomy from March 1994 to March 2004 in department of surgery at SMS medical college, Jaipur, India. Demographic variables, details of preoperative stenting, operative procedure and post operative complications were noted.RESULTS: Preoperative biliary drainage was performed in 21 patients (43.5%). The incidence of septic complications was significantly higher in patients with biliary stent placement (P < 0.05, 0 vs 4). This group of patients also had a significantly higher minor biliary leak rate. Mortality and hospital stay in each group was comparable.CONCLUSION: Within this study population the use of PBD by endoscopic stenting was associated with a high incidence of infective complications. These findings do not support the routine use of biliary stenting in patients prior to pancreatico-duodenectomy.

    Full Text Available Context Somatostatinoma is a rare neoplasm of the pancreas. Preoperative diagnosis is often difficult. Case report We report a 72-year-old woman with a pancreatic head tumor measuring 37 mm in diameter, and enlargement of the lymphnodes on the anterior surface of the pancreatic head and the posterior surface of the horizontal part of the duodenum.Laboratory data showed an elevated plasma somatostatin concentration. Examination of a biopsy specimen of thepancreatic head mass obtained by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA showedhistopathological features of a neuroendocrine tumor. Immunohistochemical staining showed that the tumor cells werepositive for somatostatin, leading to a preoperative diagnosis of pancreatic somatostatinoma. The patient underwentpylorus-preserving pancreaticoduodenectomy. The plasma somatostatin concentration decreased progressively aftersurgery. Conclusions A rare case of pancreatic somatostatinoma with lymph node metastases was presented.Immunohistochemical analysis of a biopsy specimen obtained by EUS-FNA was useful for preoperative diagnosis.

    We studied the indications for laparoscopic cholecystectomy (LC) and values of preoperative imaging findings in 82 patients who underwent preoperative imaging diagnostic tests (abdominal echogram, abdominal CAT scan, ERCP). We analyzed mainly patients who were considered to be indicated for LC but whose gallbladders could be removed by open laparotomy, or whose gallbladders were removed by open laparotomy but were considered indicated for LC from retrospective study. We found the following results. LC could be easily performed in patients with a history of severe acute cholecystitis if they had no findings of a thickened wall or negative gallbladder signs. Abdominal echogram and CAT scan were the best preoperative imaging tests for determining the gallbladder's state, especially for obstruction of the cystic duct. These results are important today when the operative indications of LC are extremely indefinite because of the accumulation of operative experience and technological improvements. (author).

    Cachexia, malnutrition, significant weight loss, and reduction in food intake due to anorexia represent the most important pathophysiological consequences of pancreatic cancer. Pathophysiological consequences result also from pancreatectomy, the type and severity of which differ significantly and depend on the type of the operation performed. Nutritional intervention, either parenteral or enteral, needs to be seen as a method of support in pancreatic cancer patients aiming at the maintenance of the nutritional and functional status and the prevention or attenuation of cachexia. Oral nutrition could reduce complications while restoring quality of life. Enteral nutrition in the post-operative period could also reduce infective complications. The evidence for immune-enhanced feed in patients undergoing pancreaticoduodenectomy for pancreatic cancer is supported by the available clinical data. Nutritional support during the post-operative period on a cyclical basis is preferred because it is associated with low incidence of gastric stasis. Postoperative total parenteral nutrition is indicated only to those patients who are unable to be fed orally or enterally. Thus nutritional deficiency is a relatively widesoread and constant finding suggesting that we must optimise the nutritional status both before and after surgery.

    Obesity affects 32% of adults in the USA. Surgery generates substantial weight loss, but 20-30% fails to achieve successful weight loss. Our objective was to identify preoperative psychosocial factors associated with weight loss following bariatric surgery. We performed a literature search of PubMed® and the Cochrane Database of Reviews of Effectiveness between 1988 and April 2010. Articles were screened for bariatric surgery and weight loss if they included a preoperative predictor of weight loss: body mass index (BMI), preoperative weight loss, eating disorders, or psychiatric disorder/substance abuse. One thousand seven titles were reviewed, 534 articles screened, and 115 included in the review. Factors that may be positively associated with weight loss after surgery include mandatory preoperative weight loss (7 of 14 studies with positive association). Factors that may be negatively associated with weight loss include preoperative BMI (37 out of 62 studies with negative association), super-obesity (24 out of 33 studies), and personality disorders (7 out of 14 studies). Meta-analysis revealed a decrease of 10.1% excess weight loss (EWL) for super-obese patients (95% confidence interval (CI) [3.7-16.5%]), though there was significant heterogeneity in the meta-analysis, and an increase of 5.9% EWL for patients with binge eating at 12 months after surgery (95% CI [1.9-9.8%]). Further studies are necessary to investigate whether preoperative factors can predict a clinically meaningful difference in weight loss after bariatric surgery. The identification of predictive factors may improve patient selection and help develop interventions targeting specific needs of patients.

    To review the records of 50 children who underwent open joint washout for septic arthritis with (n=25) or without (n=25) preoperative antibiotics. Records of 50 children who underwent open joint washout for presumed septic arthritis with (n=25) or without (n=25) preoperative antibiotics were reviewed. 17 boys and 8 girls aged 3 weeks to 16 years (median, 1.5 years) who were prescribed preoperative antibiotics before joint washout were compared with 12 boys and 13 girls aged one month to 14 years (median, 2 years) who were not. Following arthrotomy and washout, all patients were commenced on high-dose intravenous antibiotics. Patients were followed up for 6 to 18 months until asymptomatic. Patients who were referred from places other than our emergency department were twice as likely to have been prescribed preoperative antibiotics (p=0.0032). Patients prescribed preoperative antibiotics had a longer median (range) time from symptom onset to joint washout (8 [2-23] vs. 4 [1-29] days, p=0.05) and a higher mean erythrocyte sedimentation rate (93.1 vs. 54.3 mm/h, p=0.023) at presentation. Nonetheless, the 2 groups were comparable for weight bearing status, fever, and positive culture, as well as the mean (range) duration of antibiotic treatment (4.9 [4-7] vs. 4.7 [1-8] weeks, p=0.586). Preoperative antibiotics should be avoided in the management of septic arthritis in children. Their prescription delays diagnosis and definitive surgery, and leads to additional washouts and complications. A high index of suspicion and expedite referral to a specialist paediatric orthopaedic unit is needed if septic arthritis is suspected.

    Full Text Available Endale Gebreegziabher Gebremedhn, Vidhya Nagaratnam Department of Anesthesia, School of Medicine, Gondar College of Medicine and Health Sciences, University of Gondar, Gondar, Ethiopia Background: The evaluation of patient satisfaction is a core aspect of the continuous quality improvement in anesthesia service that can be affected by the preoperative anesthetist visit. This visit enables the anesthetist to know about the patient's general health status and the nature of surgery, to choose the type of anesthesia, and to discuss perioperative complications and their management with the patient. Patients have sometimes complained about the information given during the preoperative anesthetic evaluation in the University of Gondar teaching and referral hospital. The aim of this study was to determine the level of patient satisfaction with the preoperative anesthetist visit. Methods: A cross-sectional study was conducted from February 15 to April 15, 2013. All consecutive elective patients who were operated upon under anesthesia during the study period were interviewed 24 hours after operation. A pretested questionnaire and checklists, which were developed based on the hospital's anesthetic evaluation sheet, were used for data collection. Results: A total of 116 elective patients were operated upon under anesthesia during the study period. Of these, 102 patients were included in our study, with a response rate of 87.9%. Anesthetists introduced themselves to ~24% patients; provided information about anesthesia to ~32%, postoperative complications to ~21%, postoperative analgesia to ~18, and postoperative nausea and vomiting to ~21%; and spent adequate time with ~74%. Patients' questions were answered by the anesthetist in ~65% of cases, and ~65% of patients had reduced anxiety after the anesthetist visit. The patients' overall satisfaction with the preoperative anesthetist visit was ~65%. Conclusion and recommendation: Patient satisfaction with the

    Wahl, R

    1999-02-01

    This article reviews the nutritional requirements of puberty and the clinical assessment of nutritional status, and discusses the nutritional risks imposed by vegetarian diets, pregnancy, and athletic involvement. Energy (calories) and protein are essential in pubertal development. Adolescent females require approximately 2200 calories/day, whereas male adolescents require 2500-3000 calories/day. Additional intake requirements include fat, calcium, iron, zinc, vitamins, and fiber. The clinical assessment of nutritional status begins with obtaining a good diet history of the patient and this could be offered by the body mass index. Nutritional deficiencies and poor eating habits established during adolescence can have long-term consequences, including delayed sexual maturation, loss of final adult height, osteoporosis, hyperlipidemia, and obesity. As for vegetarian adolescents, nutritional risks include lack of iodine, vitamin B12, vitamin D, and some essential fatty acids. In addition, substances in some grains reduce gut absorption, thus increasing mineral deficiencies. Pregnancy may also be a risk factor for poor nutrition during adolescence. A pregnant adolescent has different nutritional needs because she is still growing. Among adolescent athletes many are turning to nutritional supplements in an attempt to improve athletic performance. A balanced, varied diet provides adequate calories and nutrition to meet the needs of most adolescents. They also have greater water needs than do adult athletes. Details on adolescent health concerns are further discussed in this article.

    Pediatric patients with chronic illnesses or diseases or who require long-term nutrition support are most vulnerable to nutrition-related issues. Malnutrition in a pediatric patient may negatively affect long-term growth and development. Children also become malnourished much more quickly than adults. A comprehensive nutrition assessment that includes food and nutrition-related history, anthropometric measurements, biochemical data, medical tests and procedures, nutrition-focused physical findings, and patient history should be completed on these patients as no one parameter is a comprehensive indicator of nutrition status. Anthropometric measurements provide important information on the growth and nutrition status of a child, yet many times it is difficult to get accurate and valid measurements due to physical limitations of the child or improper technique. Inaccurate measurements may result in a missed diagnosis of malnutrition or may lead to an incorrect diagnosis of a healthy child. Knowledge of appropriate anthropometric measurements and alternatives is crucial when assessing growth in all children and essential for those who are physically handicapped or critically ill. The purpose of this review is to present key components of a pediatric nutrition assessment so proper nutrition-related diagnosis, including malnutrition, can be accomplished, a nutrition care plan established, and expected outcomes documented.

    Background. Under-estimation of invasion components occur occasionally at core needle diagnosed ductal carcinoma in situ (DCIS) that may change the prognosis or treatment planning. Purpose. To determine whether enhanced magnetic resonance imaging (MRI) features of biopsy-proven ductal cancers in situ help predict the under-estimation of invasive breast cancers. Material and Methods. After a retrospective review of the enhanced MRI features on preoperative proven breast ductal cancers in situ by biopsy, tumor morphology (mass and non-mass), enhancing curve patterns, and non-mass enhanced appearances were compared between pure ductal cancers in situ and invasive ductal cancers (IDCs) after surgery. A statistical analysis was performed, and P values <0.05 were deemed significant. Results. Twenty-five breast cancers from 24 women were analyzed. Eleven DCIS remained as DCISs, and 14 were upgraded to IDC after surgery. Eight of 14 IDCs (57%) and one of 11 DCISs (9%) presented as mass lesions; otherwise six (43%) IDCs and 10 (91%) DCISs were non-mass lesions (P = 0.013). Among the non-mass cancers, six of 10 DCISs (60%) were focally enhanced and six of 6 IDCs (100%) were segmentally enhanced. The overall cancer sizes measured on enhanced MRI were moderately correlated with histopathology, with a Spearman's rank correlation coefficient of 0.656 (P = 0.001). The mean diameter of the IDCs was larger than that of the pure DCISs on enhanced MRI (2.69 +- 1.42 cm for IDC and 1.62 +- 1.03 cm for DCIS; P = 0.048). The cut-off size was optimally selected at 1.95 cm with a 64% sensitivity and a 77% specificity, using a receiver-operating characteristic curve. The enhancement curves, with washout or persistent rising, were statistically insignificant (P = 0.085 and 0.93, respectively). Conclusion. Enhanced MRI provided informative morphology and size features that might help to predict the underestimation of invasiveness in preoperative biopsy-proven DCIS

    AIM: To review the application of nutrition support in patientsafter surgery for colorectal cancer, and to propose appropriate nutrition strategies.METHODS: A total of 202 consecutive surgical patients admittedto our hospital with a diagnosis of colon cancer or rectal cancer from January 2010 to July 2010, meeting the requirements of Nutrition Risk Screening 2002,were enrolled in our study. Laboratory tests were performed to analyze the nutrition status of each patient,and the clinical outcome variables, including postoperativecomplications, hospital stay, cost of hospitalization and postoperative outcome, were analyzed.RESULTS: The "non-risk" patients who did not receive postoperative nutrition support had a higher rate of postoperative complications than patients who received postoperative nutrition support (2.40 ± 1.51 vs 1.23 ±0.60, P = 0.000), and had a longer postoperative hospital stay(23.00 ± 15.84 d vs 15.27 ± 5.89 d, P = 0.009).There was higher cost of hospitalization for patients who received preoperative total parenteral nutrition (TPN)than for patients who did not receive preoperative TPN(62 713.50 ± 5070.66 RMB Yuan vs 43178.00 ± 3596.68RMB Yuan, P = 0.014). Applying postoperative enteral nutrition significantly shortened postoperative fasting time(5.16 ± 1.21 d vs 6.40 ± 1.84 d, P = 0.001) and postoperative hospital stay (11.92 ± 4.34 d vs 15.77 ± 6.03 d,P = 0.002). The patients who received postoperative TPN for no less than 7 d had increased serum glucose levels(7.59 ± 3.57 mmol/L vs 6.48 ± 1.32 mmol/L, P = 0.006)and cost of hospitalization (47 724.14 ± 16 945.17 Yuan vs 38 598.73 ± 8349.79 Yuan, P = 0.000). The patients who received postoperative omega-3 fatty acids had ahigher rate of postoperative complications than the patients who did not (1.33 ± 0.64 vs 1.13 ± 0.49, P = 0.041).High level of serum glucose was associated with a high risk of postoperative complications of infection.CONCLUSION: Appropriate and moderate nutritional

In hyperacute liver failure, nutrition support is of less importance than in the other subtypes of acute liver failure that take a more protracted course. Nasoenteral tube feeding using a polymeric standard formula should be the first-line approach, while parenteral nutrition giving glucose, fat, amino acids, vitamins, and trace elements is initiated when enteral nutrition is insufficient or impracticable. In chronic liver disease, notably cirrhosis, there is frequently protein malnutrition indicating a poor prognosis and requiring immediate initiation of nutrition support. Enteral nutrition ensuring an adequate provision of energy and protein should be preferred. Particular care should be taken to avoid refeeding syndrome and to treat vitamin and trace element deficiency.

    Primary systemic treatment of breast cancer with cytotoxics yields a high response rate and allows conservative surgical procedures in bulky tumours. In order to maximise local control of disease, two innovations were introduced in a pilot study. The first was to identify the good responders after three cycles of chemotherapy and to treat them with three additional cycles. The second was to also give this group of patients a full dose of radiotherapy before surgery with the aim of verifying the rate of pathological complete remissions in view of a possible treatment of breast primary with chemoradiotherapy only. Patients were treated with doxorubicin 60 mg/m{sup 2} and cyclophosphamide, 600 mg/m{sup 2} both intravenously on day 1, every 21 days for three courses. Partial or complete responders received three more courses followed by radiotherapy (50 Gy plus a 10 Gy boost). The others underwent immediate surgery. A total of 32 patients (median age, 50 years; range 28-69 years); performance status, 0-1; T{sub 2} 22, T{sub 3} 8, T{sub 4} 2) were enrolled and were evaluable for response and side-effects. 9 patients had only three cycles of chemotherapy due to absence of response and 23 patients had six cycles of chemotherapy. Overall, 7 patients had a complete remission, 16 a partial remission and 9 had stable disease, for an overall response rate of 72% (95% confidence interval 53-86%). In the group of patients that completed the programme, two complete pathological remissions were observed and 5 patients had only microfoci of tumour. No toxic death or grade III-IV toxicities were observed. Mild or moderate side-effects included mucositis, nausea/vomiting and leucopenia. In conclusion, our results indicate that the addition of radiotherapy to pre-operative chemotherapy did not significantly enhance the incidence of pathological complete remissions. New primary treatment approaches should be explored in this subset of patients in order to improve outcome. (Copyright (c

    From July 1988 to February 1991, 130 children with the tentative diagnosis of nephroblastoma were treated preoperatively. The initial diagnostic images (excretory urography, ultrasound, CT, MRI) have been analysed both prospectively and retrospectively and the findings correlated with the intraoperative and histological results. Of the preoperatively treated patients 93.8% had a Wilms` tumour or one of its variants. Five patients had a different malignant tumour and 3 patients, i.e. 2.3% of those preoperatively treated or 1.6% of all registered patients, had benign tumours of the kidney. Wilms` tumour generally presented as a well-defined mass with an inhomogeneous morphology on CT. On ultrasound only 24% of the tumours were homogeneous. Intratumoral haemorrhage and cystic areas occurred frequently; calcifications were rare (8%). With regard to caval involvement only ultrasound and MRI enabled the correct diagnosis, while CT could not differentiate compressions from invasion. The pretherapeutic diagnostic imaging was of sufficient accuracy to start preoperative chemotherapy without diagnostic biopsy. (orig.)

    Based on previous studies, we hypothesized that the clinical phenomena of preoperative anxiety, emergence delirium, and postoperative maladaptive behavioral changes were closely related. We examined this issue using data obtained by our laboratory over the past 6 years. Only children who underwent surgery and general anesthesia using sevoflurane/O(2)/N(2)O and who did not receive midazolam were recruited. Children's anxiety was assessed preoperatively with the modified Yale Preoperative Anxiety Scale (mYPAS), emergence delirium was assessed in the postanesthesia care unit, and behavioral changes were assessed with the Post Hospital Behavior Questionnaire (PHBQ) on postoperative days 1, 2, 3, 7, and 14. Regression analysis showed that the odds of having marked symptoms of emergence delirium increased by 10% for each increment of 10 points in the child's state anxiety score (mYPAS). The odds ratio of having new-onset postoperative maladaptive behavior changes was 1.43 for children with marked emergence status as compared with children with no symptoms of emergence delirium. A 10-point increase in state anxiety scores led to a 12.5% increase in the odds that the child would have a new-onset maladaptive behavioral change after the surgery. This finding is highly significant to practicing clinicians, who can now predict the development of adverse postoperative phenomena, such as emergence delirium and postoperative behavioral changes, based on levels of preoperative anxiety.

    Surgery is a serious stressor and a cause of anxiety for the patients. Reconstructive surgery patients are mostly operated on because of certain functional impairment or disability; on the contrary, cosmetic surgery patients do not have any physical impairment and they are operated on because of mostly psychologic reasons. The aim of this study was to compare the anxiety levels in the reconstructive surgery patients and cosmetic surgery patients preoperatively. Thirty-two patients in the reconstructive surgery group and 30 patients in the cosmetic surgery group were included in the study. State Trait Anxiety Inventory was used to measure the anxiety levels in these 2 groups preoperatively. The 2 groups were similar in characteristics such as age, gender distribution, number of previous operations, and trait anxiety scores. Mean state anxiety scores obtained for the reconstructive surgery group was 38.0 +/- 8.7, while it was 44.2 +/- 10.79 for the cosmetic surgery group (t test, degrees of freedom = 60, P = 0.015). This study reveals that preoperative anxiety levels in the cosmetic surgery patients are higher than those of the reconstructive surgery patients. Therefore, adequate preoperative preparation for cosmetic surgery should include attempts to cope with anxiety. Anxiolytics may be used more liberally and professional psychologic assistance may be required.

    The purpose of the present study was to assess patients' anxiety level and information requirement in the preoperative phase. During routine preoperative screening, 320 patients were asked to assess their anxiety and information requirement on a six-item questionnaire, the Amsterdam Preoperative Anxiety and Information Scale (APAIS). Two hundred patients also completed Spielberger's State-Trait Anxiety Inventory (STAI-State). Patients were able to complete the questionnaire in less than 2 min. On factor analysis, two factors emerged clearly: anxiety and the need for information. The anxiety scale correlated highly (0.74) with the STAI-State. It emerged that 32% of the patients could be considered as "anxiety cases" and over 80% of patients have a positive attitude toward receiving information. Moreover, results demonstrated that 1) women were more anxious that men; 2) patients with a high information requirement also had a high level of anxiety; 3) patients who had never undergone an operation had a higher information requirement than those who had. The APAIS can provide anesthesiologists with a valid, reliable, and easily applicable instrument for assessing the level of patients' preoperative anxiety and the need for information.

    To evaluate the effectiveness of a psychological preoperative program in reducing preoperative anxiety and in promoting compliance of pediatric participants with surgical procedures. Fifty children and their mothers were subjected to two conditions of treatment to investigate whether psychological preparation activities and psychologist's support during all phases of the operatory iter (group 1) were as efficient in reducing mothers' and child's anxiety and in increasing the child's compliance as distraction activities (group 2). The observed child anxiety was assessed using mYPAS; compliant behaviors with Induction Compliance Checklist; and mothers' anxiety with Amsterdam Pre-operative Anxiety and Information Scale. Children of the first group were less anxious and more cooperative in the preoperative period and during anesthesia induction than in the other condition. The psychological program was also more efficient in reducing mothers' anxiety. Finally, the mothers of group 1 showed a significantly higher satisfaction and judged as significantly more effective the program proposed to prepare their children than the mothers of group 2. Preparing children through playful dramatization of the operative procedure, manipulation of medical instruments and psychologist's support may be useful in pediatric surgery structures. © 2013 Blackwell Publishing Ltd.

    To evaluate the usefulness of preoperative MRI in the patient with recurrent anorectal fistula. Fourteen patients with recurrent anorectal fistula underwent non-contrast MRI. In eight patients, T1-, T2- and proton-weighted images were taken in the axial, coronal and sagittal planes, and T1- and T2-weighted images taken in the axial and coronal planes were obtained from the other six. Fourteen cases of anorectal fistula and eight cases in which there was a combined abscess were detected. Preoperative MRI clearly showed the exact anatomical relationship with the anal sphincter, levator ani and surrounding soft tissue. In two cases in which there was fibrous scarring of the fistula tract, low signal intensities were seen on all MRI sequences. Preoperative information in the group in which only axial and coronal T1- and T2-weighted images were obtained was sufficient. Preoperative MRI in patients with recurrent anorectal fistula or suspected multiple fistulous tracts provide objective information concerning the anatomical location and extension of a fistula and combined abscess and could thus reduce the reoperation rate. An understanding of pathologic state through MRI signal intensity can help decide the most appropriate course of treatment.

    Sports nutrition in Canada has significantly evolved over the years from providing fundamental training dietary advice to applied precise assessment of nutritional status in a variety of settings, especially with the establishment of Canadian Sport Institutes and Centres across Canada. This progression has enhanced the level of dietary support to manage athletes' nutrition in a holistic perspective. Athletes are now educated about food fundamentals (acquiring foods, menu planning, preparing, food safety), personal accountability of hydration and energy monitoring (urinary and body weight assessments), individualized supplementation protocols, and customized nutrition for variable daily training environments according to their Yearly Training Plan. Sport dietitians are an important member of Integrated Sport Teams where collaboration exists amongst professionals who coordinate the athletes' personalized training and performance programming. Dietitians in sport are encouraged to continue to lobby for nutrition programming at the elite, varsity, provincial, and club levels to ensure that athletes receive accurate guidance from nutrition experts.

    The role of nutrition in the management of HIV infection and AIDS is now widely recognized. To highlight the influence of nutrition on the progress of HIV/AIDS and the role and importance of good nutrition in the management of the disease, literature selected from local and international scientific books and journals on the subject of nutrition and HIV/AIDS were reviewed and synthesized in this article. As an intervention, it should begin in the early stages of HIV infection and should include nutrition counseling, and in the later stages of the disease, using more advanced nutrition support methods including enteral and parenteral support. These would enable HIV/AIDS patients to achieve an adequate nutrient intake and energy for as long as possible, thus enhancing the quality of their lives and minimizing the symptoms of the disease.

    Preoperative anxiety is often expressed by patients requiring filtration surgery for their glaucoma. So far, there has been no scale for screening this group of patients for preoperative anxiety. The Amsterdam Preoperative Anxiety and Information Scale (APAIS) is a self-evaluation questionnaire which has been used in specialties other than ophthalmology and which makes it possible to identify the adult patients with a high level of preoperative anxiety over an upcoming surgical procedure. The purpose of this study is to estimate the preoperative anxiety in glaucoma patients requiring filtration surgery. We performed a prospective study of 36 adult patients with chronic glaucoma not responding to medical treatment and who were about to undergo filtration surgery (trabeculectomy or deep sclerectomy). The APAIS questionnaire was given to the patients after discussing the indication for surgery. A global anxiety score (ranging from 4 to 20) above 10 defined patients with a high level of preoperative anxiety. We attempted to identify among these patients the factors related to filtration surgery which caused them anxiety (lack of control of intraocular pressure, risk of blindness, presence of the filtering bleb). In our sample of patients, we found that glaucoma was a source of anxiety. That was also true for the surgical procedure, though most patients believe that once the decision had been made, their psychological status was not modified by the upcoming procedure. The patient-clinician relationship is important in any chronic disease, all the more so in glaucoma, since this disease remains asymptomatic for a long time. When filtration surgery is necessary, the patients are going to express less preoperative anxiety if they trust their physician and if individualized information has been given to them The French version of the APAIS is a quick scale, easily completed, that can be recommended for evaluating anxiety and patients' need for information prior to filtering

    Evidence pertaining to the role of dietary factors in carcinogenesis comes from both epidemiological studies and laboratory experiments. In 1982, the Committee on Diet, Nutrition, and Cancer of the National Research Council conducted a comprehensive evaluation of this evidence. That assessment as well as recent epidemiological and laboratory investigations suggest that a high fat diet is associated with increased susceptibility to cancer of different sites, particularly the breast and colon, and to a lesser extent, the prostate. Current data permit no definitive conclusions about other dietary macroconstituents including cholesterol, total caloric intake, protein, carbohydrates and total dietary fiber. Specific components of fiber, however, may have a protective effect against colon cancer. In epidemiological studies, frequent consumption of certain fruits and vegetables, especially citrus fruits and carotene-rich and cruciferous vegetables, is associated with a lower incidence of cancers at various sites. The specific components responsible for these effects are not clearly identified, although the epidemiological evidence appears to be most consistent for a protective effect of carotene on lung cancer and less so for vitamins A and C and various cancer sites. The laboratory evidence is most consistent for vitamin A deficiency and enhanced tumorigenesis, and for the ability of various nonnutritive components in cruciferous vegetables to block in-vivo carcinogenesis. The data for minerals and carcinogenesis are extremely limited, although preliminary evidence from both epidemiological and laboratory studies suggests that selenium may protect against overall cancer risk. 402 references.

    Being home to 31% of the world's children who are stunted and 42% of those who are underweight, and with many children and adults affected by micronutrient deficiencies, India is facing huge challenges in the field of nutrition. Even though the Indian Government is investing vast amounts of money into programs that aim to enhance food security, health and nutrition (the Integrated Child Development Services program alone costs 3 billion USD per year), overall impact has been rather disappointing. However, there are some bright spots on the horizon. The recent District Level Health Surveys (DLHS-4) do show significant progress, ie a reduction in stunting of around 15% over the past 6 years in a few states for which preliminary results are available. The reasons for this reduction are not unambiguous and appear to include state government commitment, focus on the 'window of opportunity', improved status and education of women, a lowered fertility rate, and combinations of nutrition- specific and nutrition-sensitive interventions. Apart from the government many other agencies play a role in driving improvements in nutrition. Since 2006 the Global Alliance for Improved Nutrition (GAIN) has worked with a range of partners to improve access to nutritious foods for large parts of the population, through public and private delivery channels. This supplement presents a selection of these activities, ranging from a capacityassessment of frontline workers in the ICDS system, large scale staple food fortification, salt iodization, fortification of mid-day meals for school children and decentralized complementary food production.

    Anemia is common in cancer patients and is associated with reduced survival. Recent studies document that treatment of anemia with blood transfusion in cancer patients is associated with increased infection risk, tumor recurrence, and mortality. We therefore investigated the incidence of preoperative anemia in colorectal cancer and assessed risk factors for anemia. Prospective data were collected on 311 patients diagnosed with colorectal cancer over a 6-year period from 1994 through 1999. Patients were stratified by age, gender, presenting complaint, preoperative hematocrit, American Joint Committee on Cancer (AJCC) stage, and TNM classification. Discrete variables were compared using Pearson's Chi-square analysis. Continuous variables were compared using Student's t test. Differences were considered significant when P colon cancer with an incidence of 57.6 per cent followed by left colon cancer (42.2%) and rectal cancer (29.8%). Patients with right colon cancer had significantly lower preoperative hematocrits compared with left colon cancer (33 +/- 8.5 vs 36 +/- 7.4; P rectal cancer (33 +/- 8.5 vs 38 +/- 6.0; P colon cancer also had significantly increased stage at presentation compared with left colon cancer (2.3 +/- 1.3 vs 2.1 +/- 1.2; P cancer. We conclude that there is a high incidence of anemia in patients with colon cancer. Patients with right colon cancer had significantly lower preoperative hematocrits and higher stage of cancer at diagnosis. Complete colon evaluation with colonoscopy is warranted in patients with anemia to improve earlier diagnosis of right colon cancer. A clinical trial of preoperative treatment of anemic colorectal cancer patients with recombinant human erythropoietin is warranted.

    Preoperative anxiety has a significant effect on the outcome of anesthesia and surgery. At present, there is no published data on the preoperative anxiety levels in Sri Lankan patients. In the West, several validated questionnaires such as The Amsterdam Preoperative Anxiety and Information Scale (APAIS) and State Trait Anxiety Inventory (STAI) are used. To measure the preoperative anxiety levels in patients using APAIS and to analyze the factors affecting anxiety and the role played by the anesthetist in allaying anxiety. One hundred patients scheduled for elective surgery were prospectively studied using the APAIS. The internal consistency was checked using Cronbach's alpha. The ages varied 25 to 72 years (mean=48.7 years, SD=13.6). Reliability of the APAIS was high; Cronbach's alpha=0.864 in the overall component and 0.84, 0.73 and 0.97 in the anxiety related to surgery, anesthesia and in the information desire components, respectively. Females were more anxious than males (p=0.02) and those who had never sustained surgery were more anxious than those who previously had surgery (p=0.05). An anesthetist's visit and premedication reduced total anxiety scores (Z=-3.07, p=0.002) and anesthesia related anxiety scores (Z=-3.45, p=0.001). The prevalence of anxiety is high among Sri Lankan patients. Females are more anxious than males and those who have never had surgery are more anxious than those who have had surgery. The anesthetist's visit could reduce anxiety. Sinhala version of the APAIS is highly reliable in assessing the preoperative anxiety levels. Copyright © 2012. Published by Elsevier B.V.

    Microvascular invasion (MVI) is a significant risk factor for early recurrence after resection or transplantation for hepatocellular carcinoma (HCC). Knowledge of MVI status would help guide treatment recommendations but is generally identified after surgery. This study aims to predict MVI preoperatively using quantitative image analysis. From 2 institutions, 120 patients submitted to resection of HCC from 2003 to 2015 were included. The largest tumor from preoperative CT was subjected to quantitative image analysis, which uses an automated computer algorithm to capture regional variation in CT enhancement patterns. Quantitative imaging features by automatic analysis, qualitative radiographic descriptors by 2 radiologists, and preoperative clinical variables were included in multivariate analysis to predict histologic MVI. Histologic MVI was identified in 19 (37%) patients with tumors ≤ 5 cm and 34 (49%) patients with tumors > 5 cm. Among patients with ≤ 5 cm tumors, none of clinical findings or radiographic descriptors was associated with MVI; however, quantitative feature based on angle co-occurrence matrix predicted MVI with area under curve (AUC) 0.80, positive predictive value (PPV) 63% and negative predictive value (NPV) 85%. In patients with > 5 cm tumors, higher α-fetoprotein (AFP) level, larger tumor size, and viral hepatitis history were associated with MVI, whereas radiographic descriptors did not. However, a multivariate model combining AFP, tumor size, hepatitis status, and quantitative feature based on local binary pattern predicted MVI with AUC 0.88, PPV 72% and NPV 96%. This study reveals the potential importance of quantitative image analysis as a predictor of MVI. Copyright © 2017. Published by Elsevier Inc.

    Pycnogenol(®) has excellent radical scavenging properties and enhances the production of antioxidative enzymes which contributes to the anti-inflammatory effect of the extract. Irradiation delivered to the abdominal region, typically results in severe damage to the intestinal mucosa. The effects of ionizing radiation are mediated by the formation of free radicals through radiolysis. Irradiation has local effects on tissues. These local effects of irradiation on the bowel are believed to involve a two-stage process which includes both short and long term components. In our study we aimed to investigate the short term effects of Pycnogenol(®) on the healing of colon anastomoses in irradiated bowel. Sixty male Wistar-Albino rats were used in this study. There were three groups: Group I, control group (n = 20); group II which received preoperative irradiation (n = 20); group III which received per oral Pycnogenol(®) before irradiation (n = 20). Only segmeter colonic resection and anastomosis was performed to the control group (Group I). The other groups (Group II, III) underwent surgery on the 5th day after pelvic irradiation. On postoperative days 3 and 7, half of the rats in each group were sacrificed and then relaparotomy was performed. There was no statistical difference between groups with respect to biochemical parameters. Bursting pressure was significantly higher in the Control and Group III compared with the Group II. In conclusion, the present study showed that preoperative irradiation effect negatively on colonic anastomoses in rats by means of mechanical parameters and administration of Pycnogenol(®) preoperatively ameliorates this unfavorable effect.

    Purpose - The purpose of this paper is to explore parenteral nutrition (PN) practices in hospital pharmacies of Kuwait and identify potential avenues for quality improvement in this service. Design/methodology/approach - A descriptive, qualitative study about PN practices was conducted from June 2012 to February 2013 in Kuwait. Data were collected via in-depth semi-structured interviews with the head total parenteral nutrition (TPN) pharmacists at seven hospitals using a developed questionnaire. The questionnaire obtained information about the PN service at each hospital including the existence of nutritional support teams (NSTs), PN preparation practices, quality controls and guidelines/protocols. The interviews were audio-recorded, transcribed verbatim and analyzed for content. Findings - Seven hospitals in Kuwait provided PN preparation service through TPN units within hospital pharmacies. Functional NSTs did not exist in any of these hospitals. All TPN units used paper-based standard PN order forms for requesting PN. The content of PN order forms and PN formulas labeling information were inconsistent across hospitals. Most of the prepared PN formulas were tailor-made and packed in single compartment bags. Quality controls used included gravimetric analysis and visual inspection of PN formulations, and less consistently reported periodic evaluation of the aseptic techniques. Six TPN units independently developed PN guidelines/protocols. Originality/value - This study revealed variations in many aspects of PN practices among the hospitals in Kuwait and provided recommendations to improve this service. Standardization of PN practices would enhance the quality of care provided to patients receiving PN and facilitate national monitoring. This can be accomplished through the involvement of healthcare professionals with expertise in nutrition support working within proactive NSTs.

    This study evaluated the use of perioperative nutritional support on Quality of Life (QOL) in malnourished head and neck cancer patients undergoing surgery. 49 Malnourished (weight loss >10%) head and neck cancer patients who were included in a nutrition intervention trial were randomized to receive either no preoperative and standard postoperative tube-feeding (group I), standard preoperative and postoperative tube-feeding (group II) or arginine-supplemented preoperative and postoperative tube-feeding (group III). Of these patients, 31 completed a full QOL assessment on the first day of preoperative nutritional support, one day before surgery, and 6 months after surgery. Both a disease-specific (EORTC QLQ-C30) and a generic questionnaire (COOP-WONCA) were used. One way analysis of variance (ANOVA) and the Kruskal-Wallis test were applied for testing differences in scores between groups. Between baseline and the day before surgery, both preoperatively fed groups revealed a positive change for the dimensions physical and emotional functioning and dyspnea (with significance in group II, P=0.050,0.031,0.045 respectively). Group III showed a negative change in appetite (P=0.049). Between baseline and 6 months after surgery, there were no differences between group I and both pre-fed groups. There were no differences in favour of group III compared to group II. Enteral nutrition improves QOL of severely malnourished head and neck cancer patients in the period preceding surgery. No benefit of preoperative enteral feeding on QOL could be demonstrated 6 months after surgery. Copyright 2000 Harcourt Publishers Ltd.

    Full Text Available We examined esophageal cancer patients who received enteral nutrition (EN to evaluate the validity of early EN compared to delayed EN, and to determine the appropriate time to start EN. A total of 208 esophagectomy patients who received EN postoperatively were divided into three groups (Group 1, 2 and 3 based on whether they received EN within 48 h, 48 h–72 h or more than 72 h, respectively. The postoperative complications, length of hospital stay (LOH, days for first fecal passage, cost of hospitalization, and the difference in serum albumin values between pre-operation and post-operation were all recorded. The statistical analyses were performed using the t-test, the Mann-Whitney U test and the chi square test. Statistical significance was defined as p < 0.05. Group 1 had the lowest thoracic drainage volume, the earliest first fecal passage, and the lowest LOH and hospitalization expenses of the three groups. The incidence of pneumonia was by far the highest in Group 3 (p = 0.019. Finally, all the postoperative outcomes of nutritional conditions were the worst by a significant margin in Group 3. It is therefore safe and valid to start early enteral nutrition within 48 h for postoperative esophageal cancer patients.

    Improving skills for accessing and utilizing diet/nutrition information is important for preventing non-communicable diseases and frailty among elderly people. With the rapidly increasing number of elderly people in the world, promoting nutrition literacy among them is a pivotal health policy for maintaining and promoting health. This article describes the barriers and catalysts of nutrition literacy among elderly Japanese people (aged ≥75 years). A cross-sectional analysis of the responses to a questionnaire administered to 678 study participants (men = 347, women = 331) was conducted. Logistic regression analysis revealed that more men had limited nutrition literacy than did women. After stratification by gender, the limited nutrition literacy group was associated with cognitive difficulty in men and women, visual impairment in men and hearing impairment in women. Lower education level and economic status were associated with limited nutrition literacy among women. Adjusted odds ratios (ORs) controlling for age, education level and economic status, as well as cognitive, visual and hearing function, indicated that informational support [OR = 5.59, 95% confidence interval (95% CI) = 1.28-24.49] and diet/nutrition information obtained from friends of the participants (OR = 2.16, 95% CI = 1.11-4.20) were both associated with adequate nutrition literacy among men, whereas diet/nutrition information from health professionals (OR = 3.96, 95% CI = 1.97-7.95) had a significant relation with adequate nutrition literacy among women. Moreover, in the adequate nutrition literacy group, men were more likely to be overweight (OR = 2.17, 95% CI = 1.20-3.91). These findings suggested that cognitive and sensory functions should be taken into account when diet information is provided to older adults. Enhancement of social networks is also a key point in improving nutrition literacy. An effective intervention to improve nutrition literacy in elderly people, particular old men

    Malnutrition increases post surgical morbimortality, hospital stance and economical costs. Possibilities of nutritional intervention in surgical patients are important. Early enteral nutrition is better than total parenteral nutrition in patients under surgery. Periroperaoty nutritional support must be administrated to patients with severe or middle undernutrition and will be under surgery, during 7-14 days before surgical intervention, if this intervention could be delayed. Total parenteral nutrition will be not used regularly in patients under mayor digestive surgical procedures. Inmunonutrition has been demonstrated useful in surgical patients. Evidence demonstrates that inmunotritional formulas decrease incidence of infections, hospital stance and time of ventilation in patients in UCI wards. New research areas have been explored in this topic area, carbohydrate utility in presurgical patients and probiotic in enteral formulas.

    Background To evaluate the role of computed tomography (CT) in preoperative diagnosis of intrathymic cyst and small thymoma, and determine the best CT threshold for distinguish intrathymic cyst from small thymoma. Methods We retrospectively reviewed the medical records of 30 patients (17 intrathymic cyst and 13 small thymoma) who had undergone mediastinal masses resection (with diameter less than 3 cm) under thoracoscope between January 2014 and July 2015 at our hospital. Clinical and CT features were compared and receiver-operating characteristics curve (ROC) analysis was performed. Results The CT value of small thymoma [39.5 HU (IQR, 33.7–42.2 HU)] was significantly higher than intrathymic cyst [25.8 HU (IQR, 22.3–29.3 HU), P=0.004]. When CT value was 31.2 HU, it could act as a threshold for identification of small thymoma and intrathymic cyst (the sensitivity and specificity was 92.3% and 82.4%, respectively). The ΔCT value of enhanced CT value with the non-enhanced CT value was significantly different between small thymoma [18.7 HU (IQR, 10.9–19.0 HU)] and intrathymic cyst [4.3 HU (IQR, 3.0–11.7 HU), P=0.04]. The density was more homogenous in intrathymic cyst than small thymoma, and the contour of the intrathymic cyst was more smoothly than small thymoma. Conclusions Preoperative CT scans could help clinicians to identify intrathymic cyst and small thymoma, and we recommend 31.2 HU as the best thresholds. Contrast-enhanced CT scans is useful for further identification of the two diseases. PMID:27621863

  6. Iatrogenic nutritional deficiencies.

    Science.gov (United States)

    Young, R C; Blass, J P

    1982-01-01

    This article catalogs the nutritional deficiencies inadvertently introduced by certain treatment regimens. Specifically, the iatrogenic effects on nutrition of surgery, hemodialysis, irradiation, and drugs are reviewed. Nutritional problems are particularly frequent consequences of surgery on the gastrointestinal tract. Gastric surgery can lead to deficiencies of vitamin B12, folate, iron, and thiamine, as well as to metabolic bone disease. The benefits of small bowel bypass are limited by the potentially severe nutritional consequences of this procedure. Following bypass surgery, patients should be monitored for signs of possible nutritional probems such as weight loss, neuropathy, cardiac arrhythmias, loss of stamina, or changes in mental status. Minimal laboratory tests should include hematologic evaluation, B12, folate, iron, albumin, calcium, phosphorus, alkaline phosphatase, transaminases, sodium, potassium, chloride, and carbon dioxide levels. Roentgenologic examination of the bone should also be obtained. Loss of bone substance is a major consequence of many forms of treatment, and dietary supplementation with calcium is warranted. Patients undergoing hemodialysis have shown carnitine and choline deficiencies, potassium depletion, and hypovitaminosis, as well as osteomalacia. Chronic drug use may alter intake, synthesis, absorption, transport, storage, metabolism, or excretion of nutrients. Patients vary markedly in the metabolic effects of drugs, and recommendations for nutrition must be related to age, sex, reproductive status, and genetic endowment. Moreover, the illness being treated can itself alter nutritional requirements and the effect of the treatment on nutrient status. The changes in nutritional levels induced by use of estrogen-containing oral contraceptives (OCs) are obscure; however, the effects on folate matabolism appear to be of less clinical import than previously suggested. Reduction in pyridoxine and serum vitamin B12 levels has been

  7. Oral health and nutrition.

    The relationships between oral health conditions, dietary practices and nutritional status, and general health status in the older American are complex, with many interrelating factors. Just as inadequate nutrition can affect oral health, poor oral health status affects food choices and, thus, nutritional status. It is clearly essential that the primary care practitioner and/or screening health professionals always include an evaluation of oral status in assessment of an elderly person. Effective care for the elderly dental patient requires knowledge about the disease of aging and the impact of those diseases on oral health and nutrition, pharmacology and drug interactions and their impact on oral health status, the biology of aging including sensory changes, the relationship of general medicine and systemic diseases, and psychology and sociology. The attitudes of empathy and understanding, caring and compassion, respect and a positive attitude toward the older patient, and flexibility in treatment planning are also critical elements. The interdisciplinary team of physicians, nurses, nutrition professionals, dentists, and social service professionals must all work together to ensure that good oral health status and adequate nutrition are maintained in older Americans. Recognizing and treating oral health and nutrition problems are important in improving the health and quality of life for the elderly population. Research that can provide more answers to health care problems in this growing group; educating professionals with respect to the relationships between oral health and nutrition; and public policy changes with regard to provision and funding of nutrition services, especially when provided by registered and/or licensed nutrition professionals, contribute to improving the health and quality of life for elders.

    This study examined the effect of implementing a new preoperative briefing protocol on self- and peer-assessments of individual operating room (OR) teamwork behaviors. From July 2006 to February 2007, OR teamwork performance at a rural community hospital was evaluated before and after training and implementation of the protocol. After each case, every member on the team completed a 360-degree type teamwork behavior evaluation containing both self- and peer-assessments using a six-point Likert type scale (1 = definitely no to 6 = definitely yes). Individual behavior change was measured using the mean scale score of pre and postprotocol assessments. Statistical analysis included t test for both pre/post and self/peer differences. Data were available for one general surgeon and nine OR staff (pre = 20 cases, post = 16 cases). The preprotocol self-assessment mean score was significantly higher than peer-assessment (5.63 vs 5.29, P teamwork behaviors. No difference was observed in postassessment mean scores for self- and peer-assessments. Individuals overestimated their teamwork behaviors before protocol implementation. Using a preoperative protocol seems to improve OR staff teamwork behaviors and self-assessment accuracy. The use of a 360-degree assessment method targeting specific, observable behaviors may be useful in evaluating team-based interventions and enhancing teamwork effectiveness.

    1993-09-01

    Recent studies have used preoperative cardiopulmonary exercise testing to improve risk assessment of pulmonary resection for lung cancer. These studies have demonstrated inconsistent correlation between peak oxygen uptake (VO2) and postoperative complications but have not systematically examined other methods of risk stratification. We analyzed the findings in 42 patients who had cardiopulmonary exercise testing prior to lung cancer resection. Preoperative clinical data combining pulmonary factors (obesity, productive cough, wheezing, tobacco use, ratio of the forced expiratory volume in 1 s over the forced vital capacity [FEV1/FVC] 45 mm Hg), and an established cardiac risk index were used to generate a cardiopulmonary risk index (CPRI). When analyzed using the risk index, the incidence of postoperative complications increased with higher CPRI scores. Those with a CPRI of 4 or greater were 22 times more likely to develop a complication, compared to a CPRI of less than 4 (p CPRI of 4 or greater was associated with significant reductions in peak VO2. We conclude that both the peak VO2 during cardiopulmonary exercise testing and a multifactorial CPRI are highly predictive of complications after lung resection. Adding the peak VO2 did not enhance the risk estimation generated by the CPRI. The association between postoperative complications and peak VO2 may be explained by the correlation between identifiable cardiopulmonary disease (CPRI) and reduced oxygen uptake with exercise.

    With the purpose of decreasing the existing variability in the criteria of preoperative evaluation and facilitating the clinical decision-making process, our hospital has a protocol of preoperative tests to use with ASA I and ASA II patients. The aim of the study was to calculate the economic impact caused by clinicians' non-adherence to the protocol for the anaesthesiological evaluation of ASA 1 and ASA II patients. A retrospective study of costs with a random sample of 353 patients that were seen in the consultation for Anesthesiology over a period of one year. Aspects related to the costs, patient's profiles and specialties were analysed, according to the degree of fulfillment of the protocol. The lack of adherence to the the protocol was 70%. 130 chest X-rays and 218 ECG were performed without indication. This generated an excess costs of 34 € per patient. Taking into account the expenses of both tests and the attended population undergoing ambulatory surgery during the one-year period, an excess spending for the hospital of between 69.164 € and 83.312 € was estimated. Clinical variability should be reduced and the creation of synergies between the different departments should be enhanced in order to adjust the request for unnecessary complementary tests to decrease health care and to improve the quality of patient care.

    Full Text Available Aim: Preoperative fasting is an established procedure to be practiced for patients before surgery, but optimal preoperative fasting time still remains controversial. The aim of this study was to investigate the effect of “shortened preoperative fasting time” on the change in the amount of total body water (TBW in elective surgical patients. TBW was measured by multi-frequency impedance method.Methods: The patients, who were scheduled to undergo surgery for stomach cancer, were divided into two groups of 15 patients each. Before surgery, patients in the control group were managed with conventional preoperative fasting time, while patients in the “enhanced recovery after surgery (ERAS” group were managed with “shortened preoperative fasting time” and “reduced laxative medication.” TBW was measured on the day before surgery and the day of surgery before entering the operating room. Defecation times and anesthesia-related vomiting and aspiration were monitored.Results: TBW values on the day of surgery showed changes in both groups as compared with those on the day before surgery, but the rate of change was smaller in the ERAS group than in the control group (2.4±6.8% [12 patients] vs. −10.6±4.6% [14 patients], p<0.001. Defecation times were less in the ERAS group. Vomiting and aspiration were not observed in either group.Conclusion: The results suggest that preoperative management with “shorted preoperative fasting time” and “reduced administration of laxatives” is effective in the maintenance of TBW in elective surgical patients.

    The effect of the histamine-2 receptor antagonist ranitidine (100 mg intravenously every 12 hours for 72 hours) on postoperative serum antibody responses to preoperative immunization with six limit of flocculation tetanus toxoid and six limit of flocculation diphtheria toxoid was assessed...... in a double-blind, placebo-controlled randomized study in 26 patients undergoing major abdominal surgery. The preoperative antitetanus antibody level was less than 0.1 IU/ml in all patients, and they were inoculated with both antigens 48 hours before surgery. Serum samples for analysis of antitetanus toxoid...... and antidiphtheria toxoid were drawn before skin incision and on postoperative days 1, 3, 5, 7, 10, 14, 21, and 28. Ranitidine significantly increased the postoperative antibody response to tetanus toxoid, (p less than 0.01) and insignificantly increased that to diphtheria toxoid vaccination (p less than 0...

    Full Text Available Adult intussusception is rare, accounting for only 5% of all intussusceptions, for which preoperative diagnosis is difficult. We herein report a preoperatively diagnosed case of adult intussusception caused by a small bowel lipoma. A 33-year-old man was admitted to our hospital with three weeks history of colicky epigastric pain. Computed tomography revealed thickening of the ileal wall suggestive of intussusception. Colonoscopy revealed an ileocolic intussusception. Barium enema for reduction of ileocolic intussusception demonstrated a small bowel tumor in the ileum 15 cm proximal to the ileocecal valve. The intussusception was reduced, and the patient underwent partial resection of the ileum encompassing the small bowel tumor. Histological findings confirmed the diagnosis of lipoma of the small bowel. The patient made a satisfactory recovery and remains well.

    mechanism. AIMS: To investigate the correlation between pre-operative pain intensity and sensory functions in the groin hernia area. METHODS: Patients with unilateral groin hernia were examined preoperatively by quantitative sensory testing (thermal, mechanical, and pressure [detection and pain thresholds...... (rho=-0.413, p=0.049), indicating a paradoxical association between level of mechanical pain threshold and magnitude of spontaneous pain. No other sensory modality was significantly correlated to pain intensity. New/increased pain during repetitive pinprick stimulation (wind-up) was seen in 3 patients......]) and assessments were correlated to patients' reports of intensity and frequency of spontaneous pain in the groin area. RESULTS: Forty-two patients were examined, whereof one was excluded since no hernia was found intraoperatively. Mechanical pain threshold was inversely correlated with spontaneous pain intensity...
