Can We Rely on Predicted Basal Metabolic Rate in Patients With Intestinal Failure on Home Parenteral Nutrition?

Background and Aims: Intestinal failure (IF) is a serious and common complication of short bowel syndrome with patients depending on parenteral nutrition (PN) support. Effective nutrition management requires an accurate estimation of the patient's basal metabolic rate (BMR) to avoid underfeeding or overfeeding. However, indirect calorimetry, considered the gold standard for BMR assessment, is a time‐ and resource‐consuming procedure. Consequently, several equations for prediction of BMR have been developed in different settings, but their accuracy in patients with IF are yet to be investigated. We evaluated the accuracy of predicted BMR in clinically stable patients with IF dependent on home parenteral nutrition (HPN). Methods: In total, 103 patients with IF were included. We used indirect calorimetry for assessment of BMR and calculated predicted BMR using different equations based on anthropometric and/or bioelectrical impedance parameters. The accuracy of predicted BMR was evaluated using Bland‐Altman analysis with measured BMR as the gold standard. Results: The average measured BMR was 1272 ± 245 kcal/d. The most accurate estimations of BMR were obtained using the Harris‐Benedict equation (mean bias, 14 kcal/d [P = .28]; limits of agreement [LoA], ?238 to 266 kcal/d) and the Johnstone equation (mean bias, ?16 kcal/d [P = .24]; LoA, ?285 to 253 kcal/d). For both equations, 67% of patients had a predicted BMR from 90%–110% All other equations demonstrated a statistically and clinically significant difference between measured and predicted BMR. Conclusions: The Harris‐Benedict and Johnstone equations reliably predict BMR in two‐thirds of clinically stable patients with IF on HPN.     

Prematurity Reduces Functional Adaptation to Intestinal Resection in Piglets

Background: Necrotizing enterocolitis and congenital gastrointestinal malformations in infants often require intestinal resection, with a subsequent risk of short bowel syndrome (SBS). We hypothesized that immediate intestinal adaptation following resection of the distal intestine with placement of a jejunostomy differs between preterm and term neonates. Methods: Preterm or term piglets were born by cesarean section and fed enterally for 2 days. On day 2, piglets were subjected to 50% distal intestinal resection with placement of a jejunostomy. On the following 4–5 days, piglets received parenteral nutrition with gradually increasing doses of enteral nutrition (bovine colostrum). Intestinal tissue samples were collected at delivery and 2 and 6–7 days after birth for histological examination and assessment of digestive enzyme activities. Results: Preterm and term piglets showed similar increases in intestinal weight and digestive enzyme activities from birth to 2 days. On days 6–7 after birth, the remnant intestine showed a similar density (g/cm) and mucosal mass in term and preterm piglets, but villus height, crypt depth, enzyme activities (sucrase, maltase, dipeptidyl peptidase IV [DPPIV]), and hexose uptake capacity were significantly higher in term piglets (P < .05). Preterm piglets were more prone to develop hypoglycemia, respiratory distress syndrome, dehydration, and circulatory instability after surgery compared with term piglets. Conclusion: Studies on intestinal adaptation after resection are feasible in both preterm and term piglets, but intensive clinical support is required when rearing preterm piglets with SBS. Physiological instability and immaturity of the intestine may explain the fact that immediate adaptation after resection is reduced in preterm vs term neonates.     

Early Pregnancy Blood Lead and Spontaneous Abortion

Although evidence tends to suggest that high levels of lead exposure increase the risk of spontaneous abortion, we do not yet know whether moderate- to low-level exposure elevates risk. Among 351 women (aged 16 to 35 years, with single pregnancies) who were registered for a longitudinal study, 15 (4.3%) women experienced spontaneous abortion after the 12th week of gestation and before the 20th week. We collected participants' blood samples during the first trimester of pregnancy (8–12 weeks) for lead measurement by inductively coupled plasma-mass spectrometry. Mean ± standard deviation of blood lead was 3.8 ± 2.0 μg/dl (range 1.0–20.5 μg/dl) with a geometric mean of 3.5 μg/dl. Mean blood lead concentrations did not differ significantly between spontaneous abortion cases and ongoing pregnancies (3.51 ± 1.42 and 3.83 ± 1.99 μg/dl, respectively). The findings suggest that in apparently healthy women, low blood lead levels (mean <5 μg/dl) measured in early pregnancy may not be a risk factor for spontaneous abortion.     

Modulation of Intestinal Inflammation by Minimal Enteral Nutrition With Amniotic Fluid in Preterm Pigs

Background: Necrotizing enterocolitis (NEC) is a severe inflammatory disorder, associated with the difficult transition from parenteral to enteral feeding after preterm birth. We hypothesized that minimal enteral nutrition (MEN) with amniotic fluid (AF), prior to enteral formula feeding, would improve resistance to NEC in preterm pigs. Methods: Experiment 1: IEC‐6 cells were incubated with porcine (pAF) and human AF (hAF) to test AF‐stimulated enterocyte proliferation and migration in vitro. Experiment 2: Cesarean‐delivered, preterm pigs were fed parenteral nutrition and MEN with pAF, hAF, or control fluid (MEN‐pAF, MEN‐hAF, or MEN‐CTRL; all n = 9) for 2 days before tissue collection. Experiment 3: Preterm pigs were fed MEN diets as in experiment 2, but followed by 2 days of enteral formula feeding, which predisposes to NEC (NEC‐pAF, NEC‐hAF, or NEC‐CTRL; n = 10–12). Results: Both pAF and hAF stimulated enterocyte proliferation and migration in vitro. In experiment 2, MEN‐pAF and MEN‐hAF pigs showed increased body weight gain and reduced intestinal interleukin (IL)–8 and colonic IL‐6 levels, indicating reduced inflammatory response. In experiment 3, body weight gain was highest in the 2 groups fed AF as MEN, but NEC incidences were similar (NEC‐pAF) or increased (NEC‐hAF) compared with controls. Conclusions: Intake of pAF or hAF improved body growth and modulated intestinal inflammatory cytokines during a period of parenteral nutrition, but did not protect against later formula‐induced NEC in preterm pigs. Further studies are required to show if MEN feeding with species‐specific AF, combined with an optimal enteral diet (eg, human milk), will improve adaptation during the transition from parenteral to enteral feeding in preterm neonates.     

Development of health‐related quality of life and symptoms in patients with advanced cancer in Greenland

A prospective national cohort study assessed the development of health‐related quality of life (HRQoL) and symptoms in adult patients undergoing treatment and care for advanced cancer in Greenland. HRQol was examined by EORTC QLQ‐C30 version 3.0 questionnaire monthly for 4 months. Changes over time and between‐group comparisons were examined. Of 58 patients included in the study, 47% completed the questionnaire four times. Functioning was generally high, and improved social functioning was observed after 1 and 2 months. The highest symptom score was for fatigue followed by pain and nausea/vomiting. A high score for financial problems remained unchanged during the entire period. Patients with higher income had reduced pain intensity (p = .03) and diarrhoea (p = .05) than patients with income below the poverty line. After 1 month, reduction in pain intensity was observed for Nuuk citizens compared with non‐Nuuk citizens (p = .05). After 2 months, non‐Nuuk citizens reported improved social functioning compared with Nuuk citizens (p = .05). After 3 months, Global Health in Nuuk citizens was improved compared with non‐Nuuk citizens (p = .05). An important clinical finding was that patients’ needs for support are related to social status, and geographical factors should be taken into account when planning palliative care.     

Nurses' creativity, tedium and burnout during 1 year of clinical supervision and implementation of individually planned nursing care: comparisons between a ward for severely demented patients and a similar control ward

The aim of this study was to study creativity and innovative climate, tedium and burnout among the nurses on two wards during 1 year of systematic clinic supervision combined with the implementation of individualized care on an experimental ward (EW) for severely demented patients, as compared with a similar control ward (CW) EW nurses had systematic clinic supervision and each patient had his/her nursing care carefully planned, documented and evaluated The intervention was evaluated by means of the Creative Climate Questionnaire, Burnout Measure and the Maslach Burnout Inventory Creativity and innovative climate improved significantly among the EW nurses ( n = 19) in eight out of 10 factors during the year of intervention while there was no change on the control ward ( n = 20) Tedium and burnout decreased significantly among the EW nurses while no change was seen in this respect among the CW nurses It seems reasonable to assume that systematic clinical supervision and individualized planned care decreases the negative outcome of stress caused by the psychological burden imposed by nursing care It also increases nurses' creativity, which, in turn, may benefit patient care The findings of this study point to the necessity for a support system that focuses on the work itself, i e the nursing care Individualized planned care and systematic clinical supervision may offer this kind of support     

Empathy, experience of burnout and attitudes towards demented patients among nursing staff in geriatric care

A non-anonymous questionnaire was distributed to all nursing staff (n = 557) including RNs, LPNs (psychiatric), LPNs (somatic) and nurses' aides, in one nursing home, one somatic long-term care clinic and one psychogeriatric clinic. Scales measuring empathy, burnout experience and attitudes towards demented patients were included in the questionnaire. The aim of the study was to compare levels of empathy, burnout experience and attitudes among different categories of nursing staff and to examine connections between empathy, burnout and attitudes. The nursing staff showed an overall figure of moderately well-developed empathy and the RNs showed the highest empathy. The RNs had a significantly lower degree of burnout compared to the nurses' aides and the LPNs. Of all respondents, 27.4% were assessed at risk from burnout. Overall, the staff showed a moderately positive attitude towards demented patients and the RNs were most positive. No linear correlation was found between empathy, burnout experience and attitudes. However, a weak negative correlation between burnout and empathy is in accordance with other authors who are suggesting that burnout experience leads to lower empathy in the nursing staff. The fact that the RNs showed the most positive attitudes towards demented patients and had the highest level of empathy compared to LPNs and nurses' aides could be related to lower degree of burnout assessed in the RNs. Qualitative and quantitative overload among the LPNs and nurses' aides connected to the growing number of demented patients in the institutions examined are discussed.     

Advanced Education in Prosthodontics: Residents’ Perspectives on Their Current Training and Future Goals

Purpose: The purposes of this study were to identify current prosthodontic residents’ demographics and to document prosthodontic residents’ perspectives on their clinical training and future goals. Materials and Methods: A 52‐item survey was created and distributed to prosthodontic residents in the United States on February 8, 2007. The data collected were analyzed; the means and standard deviations were calculated and ranked. Statistical analysis was conducted using Chi‐square and Mann‐Whitney analysis (p= 0.05). Results: A 43% response rate was achieved, representing approximately 48% of the total population of prosthodontic residents in the United States. The majority of residents ranked clinical education as the most important factor in selecting their programs, were satisfied with their training, and planned to pursue the certification of the American Board of Prosthodontics. When asked how often they planned to work, 4 days a week was the most common answer. Conclusion: This is the first report identifying current prosthodontic residents’ demographics and their perspectives on their clinical training and future goals. Several trends were identified, indicating a bright future for the specialty. By knowing the students’ perceptions regarding their training and future goals, the American College of Prosthodontists and/or program directors will be able to use this information to improve residency programs and the specialty.     

Extensive Pathological Analysis of Selected Melanoma Sentinel Lymph Nodes: High Metastasis Detection Rates at Reduced Workload

Background Extensive pathological workup of sentinel lymph nodes (SLNs) in melanoma detects more patients with metastasis-positive SLNs than do routine protocols, but at the cost of high laboratory workloads. We aimed to design a protocol that reduced this workload without compromising metastasis detection. Methods We analyzed 920 SLNs from 321 consecutive patients with melanoma by complete step sectioning and immunohistochemistry. We designed different models to theoretically reduce the number of histological sections examined and compared the results from these simulations with results obtained with our extended protocol, with the restricted national Danish protocol, and with the protocol recommended by the European Organization for Research and Treatment of Cancer (EORTC). Results The extended protocol increased the metastasis detection rate by 22% (95% confidence interval, 11–34; 30.8% vs. 25.2%, P < .0001) compared with the national Danish protocol, and it had a similar rate to that reported by the EORTC (30.8% vs. 29.4%, P = .6229). The workload associated with complete step sectioning could be reduced by 40% by focusing step sectioning on the SLNs with the highest gamma counts, while examining SLNs with lower gamma counts with one to three central sections. The false-negative rate for detecting metastases with this reduced protocol was 6% compared with complete step sectioning. Conclusions Combining complete step sectioning of SLNs with immunohistochemistry ensures high metastasis detection rates. Workloads can be markedly reduced with only a slight increase in the false-negative rate by focusing analysis on the SLNs most likely to contain metastases, i.e., those with the highest gamma counts.
