Risk factors for postoperative complications in preterm infants with surgical necrotizing enterocolitis and associated outcomes.

BACKGROUND: We aim to determine clinical risk factors for postoperative complications in preterm infants with surgical necrotizing enterocolitis (NEC) or spontaneous intestinal perforation (SIP). METHODS: A retrospective cohort study of preterm infants with surgical NEC or SIP to compare clinical factors between those with and without postoperative complications. RESULTS: 78/109 (71.5%) infants had any complication following surgical NEC. Adhesions (20/35, 57.1%) and wound infection (6/35, 17.1%) were the most common single surgical complications. Patients with a single surgical complication (35/66, 53%) were significantly less likely to be exposed to antenatal steroids, more frequently had a jejunostomy, needed a central line longer, and had a longer length of stay than those without any surgical complication. Infants with > 1 surgical complication (43/71, 60.5%) included mainly females, and had AKI more frequently at NEC onset, lower weight z-scores and lower weight for length z- scores at 36 weeks PMA than those without any complications.On multinomial logistic regression, antenatal steroids exposure (OR 0.23 [CI 0.06, 0.84]; p = 0.027) was independently associated with lower risk and jejunostomy 4.81 (1.29, 17.9) was independently associated with higher risk of developing a single complication. AKI following disease onset (OR 5.33 (1.38, 20.6), P = 0.015) was independently associated with > 1 complication in surgical NEC/SIP infants. CONCLUSION: Infants with postoperative complications following surgical NEC were more likely to be female, have additional morbidities, and demonstrate growth failure at 36 weeks PMA than those without surgical complications. There was no difference in mortality between those with and without surgical complications.

Comparing different approaches in robotic-assisted surgery for unicompartmental knee arthroplasty: outcomes at a short-term follow-up of MAKO versus NAVIO system.

The popularity of unicompartmental knee arthroplasty (UKA) continues to grow among orthopaedic surgeons and robotic surgery may be helpful in obtaining a precise placement of the prosthetic components, thanks to the meticulous intra-operative computer study for simulating the prosthetic positioning. This may lead to longer implant survivorship as well as a reduction in intermediate and long-term prosthetic complications, despite the initial greater costs than those of manual UKA. In this preliminary study, from January 2017 and October 2017, 18 patients underwent UKA with MAKO robotic system assistance and 10 patients received UKA with NAVIO robotic system assistance. The two groups were homogeneous by age, BMI, degree of osteoarthritis involvement, and postoperative program. Patients were followed both clinically (Numeric Rating Scale NRS and Knee Injury Osteoarthritis Outcome Scores KOOS) and radiographically. At the end term follow up (2 years), no significant difference was observed for NRS and KOOS as well as for clinical parameters as an active range of motion. A significant discrepancy was detected regarding the duration of the surgery and time of using the robotic system, that appeared to be longer in the NAVIO group than that of MAKO group, likely due to the specific technical aspects that characterize these two different robotic systems. The main finding of this study is that favorable clinical and radiographical results may be obtained using a robotic approach (MAKO or NAVIO) for UKA positioning at a short follow up. Due to the lack of significant clinical differences observed between the two groups of patients at end term follow up, the "concept" of a robotic approach, more than a specific patented system, may be considered the key element for improving UKA technique and it is likely that in the near future the choice of a single specific robotic system will still be a "surgeon's preference". The results of the study add scientific evidence regarding the effective improvement of UKA results using different robotic approaches. They also show possible economic sustainability of this therapeutic strategy related to the optimal patients' performance obtained at short term follow up, suggesting that the robotic assistance may really become a key element for better long-term survivorship of unicompartmental knee arthroplasty.

The predictive role of pelvic magnetic resonance in the follow up of spontaneous or induced puberty in turner syndrome.

Puberty is a critical age for patients with Turner syndrome (TS): infertility is reported to be linked to karyotype and spontaneous puberty and menarche occur in approximately 30% of patients, especially in mosaicism. However, it is not always predictable considering hormonal pattern and pelvic transabdominal ultrasound scan (US).The aim of the study is to compare the accuracy of Magnetic Resonance Imaging (MRI) and US to evaluate uterine and gonads volume, to visualize the presence of follicles and to predict spontaneous puberty and menarche in girls with TS. In a retrospective study, we evaluated 19 TS patients (age: 9-16 years), who underwent transabdominal pelvic US and pelvic MRI as required by parents. We correlated pelvic imaging with karyotype, hormonal data and pubertal outcome, and we compared US resolution to MRI.MRI revealed a higher accuracy in the study of uterus and ovaries, and permitted to measure ovaries not visualized by US. Ovarian volume, the presence of follicles and the occurrence of spontaneous puberty were not related to the karyotype; spontaneous puberty started in one patient with a karyotype 45,X and in two patients with mosaicism (45,X/46,XX; 47,XXX/45, X). Ovarian follicles were relieved by MRI in patients with a spontaneous menarche and the persistence of menstrual cycles correlated with an ovarian volume corresponding to Tanner stage 3-4. We stress the role of MRI in the follow-up of TS adolescents, guide in the choice of the timing of treatment.

A cross-cultural investigation of attachment style, catastrophizing, negative pain beliefs, and symptom severity in irritable bowel syndrome.

BACKGROUND: Little information exists regarding whether psychosocial variables in irritable bowel syndrome (IBS) vary by geographic location. Adult attachment is an important psychological concept rooted in childhood relationship experience that has not been previously studied in IBS. Catastrophizing and negative pain beliefs have been described in IBS and may be affected by attachment. AIMS: In this cross-cultural study, we determined: (i) whether attachment differs between IBS patients and controls, (ii) whether geographic location has a significant effect on attachment style, catastrophizing and negative pain beliefs, and (iii) how all three variables correlate with IBS symptom severity. METHODS: 463 IBS patients, with moderate to severe symptom scores, and 192 healthy controls completed validated questionnaires about attachment, catastrophizing, negative pain beliefs and IBS-SSS in nine locations, USA (New York, Los Angeles), Mexico, Italy (Rome, Bari), Romania, Iran, India, and China. KEY RESULTS: Attachment anxiety and avoidance scores were significantly higher in IBS patients than in controls (p < 0.001). This was particularly true for the fearful-avoidant attachment category, especially in China and Romania. Path analysis showed that attachment anxiety and avoidance had indirect effects on IBS-SSS through catastrophizing (p < 0.0001) and negative pain beliefs (p = 0.005). All three psychosocial measures varied significantly depending on location. CONCLUSIONS & INFERENCES: In the IBS population studied, attachment style was significantly different in IBS compared to a control population. Geographic differences in attachment, catastrophizing and negative pain beliefs were documented and their correlation with symptom severity and thus, research of psychosocial variables in IBS should take into account the location of the population studied.

Type A behaviour: a reappraisal of its characteristics in cardiovascular disease.

AIMS: The role of type A behaviour in cardiovascular disease is controversial and most of the research is based on self-rating scales. The aim of this study was to assess the prevalence of type A behaviour in cardiology and in other medical settings using reliable interview methods that reflect its original description. METHODS: A sample of 1398 consecutive medical patients (198 with heart transplantation, 153 with a myocardial infarction, 190 with functional gastrointestinal disorders, 104 with cancer, 545 with skin disorders and 208 referred for psychiatric consultation) was administered the Structured Clinical Interview for the DSM-IV and the Structured Interview for the Diagnostic Criteria for Psychosomatic Research (DCPR) which identifies 12 clusters, including type A behaviour. RESULTS: A cardiac condition was present in 366 patients. There was a significant difference in the prevalence of type A behaviour in cardiovascular disease (36.1%) compared with other medical disorders (10.8%). Type A behaviour frequently occurred together with psychiatric and psychosomatic disturbances, particularly irritable mood, even though in the majority of cases it was not associated with DSM-IV diagnoses. Among cardiac patients, those with type A behaviour were less depressed, demoralised and worried about their illness. CONCLUSIONS: Type A behaviour was found to occur in about a third of cases of patients with cardiovascular disease. Only in a limited number of cases was it associated with depression. It has a lifestyle connotation that may have important clinical consequences as to stress vulnerability and illness behaviour.

A cluster analysis-derived classification of psychological distress and illness behavior in the medically ill.

BACKGROUND: The classification of psychological distress and illness behavior in the setting of medical disease is still controversial. Current psychiatric nosology does not seem to cover the spectrum of disturbances. The aim of this investigation was to assess whether the joint use of DSM-IV categories and the Diagnostic Criteria for Psychosomatic Research (DCPR), that provide identification of syndromes related to somatization, abnormal illness behavior, irritable mood, type A behavior, demoralization and alexithymia, could yield subtyping of psychosocial variables in the medically ill. METHOD: A cross-sectional assessment using both DSM-IV and the DCPR was conducted in eight medical centers in the Italian Health System. Data were submitted to cluster analysis. Participants were consecutive medical out-patients and in-patients for whom a psychiatric consultation was requested. A total of 1700 subjects met eligibility criteria and 1560 agreed to participate. RESULTS: Three clusters were identified: non-specific psychological distress, irritability and affective disturbances with somatization. CONCLUSIONS: Two-step cluster analysis revealed clusters that were found to occur across clinical settings. The findings indicate the need of expanding clinical assessment in the medically ill to include the various manifestations of somatization, illness behavior and subclinical distress encompassed by the DCPR.

A review of medication reconciliation issues and experiences with clinical staff and information systems.

Medication reconciliation was developed to reduce medical mistakes and injuries through a process of creating and comparing a current medication list from independent patient information sources, and resolving discrepancies. The structure and clinician assignments of medication reconciliation varies between institutions, but usually includes physicians, nurses and pharmacists. The Joint Commission has recognized the value of medication reconciliation and mandated implementation in 2006; however, a variety of issues have prevented simple, easy, and universal implementation. This review references issues related to the development and the implementation of medication reconciliation including: - the need of a system or standard for accurate drug identification to create a definitive 'gold standard' patient medication list, - identifying stakeholders of medication reconciliation within the institution and contrasting staff interest and participation with institutional resources, - observations and opportunities of integrating medication reconciliation with the electronic patient health record, and - summarizing a series of institutions experiences developing and implementing medication reconciliation. Last, as medication reconciliation becomes a regular process within medical centers, key concepts for effective implementation are discussed.

Emotional symptoms, quality of life and cytokine profile in hemodialysis patients.

BACKGROUND: Mental disorders are frequent in hemodialysis (HD) patients. Depression and anxiety along with physical co-morbidity affect quality of life (QOL). Uremia is associated with inflammation and release of cytokines by lymphomonocytes. Inflammatory cytokines are relevant in depression. The aim of this study was to assess the psychological alterations and QOL in HD patients, and to correlate them with pattern of cytokine production. PATIENTS: 30 HD patients and 20 subjects with CKD Stage I-II K-DOQI. Psychometric tests were administered: 1) Hospital Anxiety and Depression Scale (HADS) composed of an anxiety subscale (HADS-A) and a depression subscale (HADS-D); 2) Kidney Disease Quality of Life (KDQOL) modified, including a cognitive function subscale (KDQOL-CF). Whole blood samples collected at beginning of HD session were diluted with RPMI/heparin and incubated for 24 h in presence of lipopolysaccharide (LPS). IL-1Gamma, IL-6, TNF-alpha and IL-10 were assayed on supernatants and results were normalized per number of lymphomonocytes (ng/106 cells). RESULTS: A depressive mood was more frequent in HD patients (50%) than controls (20%, p < 0.0001). No difference for anxiety (HD = 43%, controls = 45%) was observed. QOL score was significantly lower in HD than controls (p = 0.006) and correlated inversely with HADS total, HADS-A and HADS-D (p < 0.0001). Albumin, Kt/V and phosphate were comparable in patients with or without anxiety or depression. Cytokine production was significantly higher in HD patients than controls (IL-1beta p = 0.05; IL-6 p = 0.010; TNF-alpha p < 0.0001; IL-10, p = 0.0019). HD patients with the HADS-A positive for anxiety showed higher IL-6 production (p = 0.026), while IL-1beta levels were not associated with symptoms of depression. KDQOL-CF correlated inversely with levels of IL-6, TNF-alpha and IL-10. CONCLUSIONS: HD patients have symptoms of depression and anxiety that negatively affect QOL. These symptoms are independent of the efficiency of dialysis and nutritional status. On the contrary, IL-6 is linked to the presence of psychological discomfort in these patients.

Practice ordering guidance for neonatal parenteral nutrition.

OBJECTIVE: Neonatal parenteral nutrition (PN) is designed for very low birth weight infants (BW < or = 1500 g) for whom enteral feedings are inadequate. Evaluating the clinical practice guidance (CPG) content of printed paper order forms could provide a baseline for comparison and serve as a reference for electronic neonatal nutrition order design systems. METHODS: A scoring system for clinical practice guidance was developed and applied to nine institutions printed paper PN order forms. CPG scores were assigned as: (1) generic reminder only, (2) prompt with order entry space, (3) patient specific reminder only, (4) patient specific recommendation with order entry space. User-friendliness and form completion time were also recorded. RESULTS: The overall CPG score for the six most common PN components was 1.85+/-0.68 (mean+/-1s.d.), consistent with a generic reminder, but short of a specific nutrient dose order field. Amino acid received the highest CPG score, 2.05+/-0.64; vitamins rated the lowest. The institution of origin was an independent predictor of the CPG score. CONCLUSIONS: Paper neonatal PN order forms offer relatively little CPG. Significant form variation and format reflects the need to standardize neonatal PN design as the neonatal PN design moves from paper to electronic ordering systems.

Persistent dyspepsia after laparoscopic cholecystectomy. The influence of psychological factors.

BACKGROUND: Many patients with gallstone disease continue to report gastrointestinal symptoms after cholecystectomy, but the predictive value of preoperative factors is not well understood. We aimed to investigate whether psychological symptoms can be associated with poor outcome after cholecystectomy in patients with gallstones and dyspepsia. METHODS: A sample of 52 consecutive patients with uncomplicated gallstone disease and dyspepsia (conceived in a broader sense to include symptoms of the whole digestive tract) were assessed for psychological (revised 90-item Hopkins Symptom Checklist) and gastrointestinal symptoms (Gastrointestinal Symptom Rating Scale). One year after laparoscopic cholecystectomy, patients rated their gastrointestinal symptoms and were divided into improved and unimproved on the basis of the change in symptoms. RESULTS: Twenty-one (40.4%) patients did not improve after surgery. Improved and unimproved patients did not differ in terms of sex, age, education or illness duration. Unimproved patients showed significantly higher psychological and dyspeptic symptoms than improved patients before surgery. Logistic regression showed that psychological factors were significantly associated with unimprovement after surgery. CONCLUSIONS: Patients with gallstone disease and dyspeptic symptoms are unlikely to improve 1 year after surgery if they show psychological distress before surgery. Psychological symptoms were strongly associated with poor post-cholecystectomy outcome, thus highlighting the clinical relevance of joint assessment of psychological and gastrointestinal symptoms before surgery.

Criterion-related validity of the diagnostic criteria for psychosomatic research for alexithymia in patients with functional gastrointestinal disorders.

BACKGROUND: Because of criticism made against psychiatric assessment of somatization, alternative Diagnostic Criteria for Psychosomatic Research (DCPR) have been proposed by an international group of psychosomatic investigators. One of these criteria concerns the alexithymia construct. The main aim of the present study was to investigate the criterion-related validity of the DCPR for alexithymia syndrome (DCPR-A). A secondary aim was to explore the relationship between alexithymia and depressed mood. METHOD: The study included 190 consecutive outpatients with functional gastrointestinal disorders. Alexithymia was assessed by means of the DCPR-A and the 20-item Toronto Alexithymia Scale (TAS-20). Depressed mood was assessed on the basis of the Depression subscale of the Hospital Anxiety and Depression Scale (HDS) and the DSM-IV criteria. RESULTS: The sensitivity of the DCPR-A together with the TAS-20 was 70.2%, specificity was 81.6%, positive predictive power 88.9%, negative predictive power 66.0% and overall hit rate 46.8%. DCPR-A positives scored significantly higher than DCPR-A negatives on the TAS-20 scores (t = 9.86, p < 0.001). The TAS-20 was not associated with any measure of depression, while the DCPR-A was significantly associated with the HDS and DSM-IV criteria. CONCLUSIONS: The DCPR-A had adequate sensitivity, specificity and accuracy, thus proving that the criterion has good validity. The differences in association found between alexithymia and depression suggest that they may be due to differences in the methods of investigation rather than to the constructs per se.

An electronic documentation system increases diagnostic code capture for very low birth weight infants.

INTRODUCTION: Information describing medical interventions and patient outcome of very low birth weight (VLBW; BW <1500 grams) infants who receive neonatal intensive care is necessary to evaluate the quality of health care. We developed an electronic patient documentation system (EDS) called PCode to identify and select patient diagnostic (DX) codes and compared EDS to the previous paper-based documentation system (PDS). Our hypothesis was that EDS would capture more patient diagnostic codes than PDS. METHODS: PDS was originally developed as a two page 'code sheet' which listed all 275 neonatal diagnoses/management options and corresponding 3-4 character diagnostic (DX) codes, organized by organ system. PDS code sheets were manually completed by one of three trained 'coders' for every neonatal patient. EDS was developed as a Java application with the 'coder' selecting DX codes from drop lists also categorized by organ system. The study intervention was patient code selection using either the PDS or the EDS system. Both systems produced a paper DX code summary. PDS data capture occurred from 11/1997-3/1999 followed by EDS data capture until 8/2000. The primary outcome variable was DX codes captured per patient. Data were analyzed using independent t-test and linear regression. RESULTS: The number of diagnoses increased with decreasing birth weight. After linear regression was applied to control for birth weight, the number of DX codes was 31% greater in the EDS group, 7.2 +/- 2.9 DX codes/patient, p=0.008. There was a trend towards fewer erroneous DX codes in the EDS group. The most common DX codes were hyaline membrane disease, sepsis evaluation and hyperbilirubinemia, as expected for this patient population. CONCLUSIONS: EDS captured more VLBW infant DX codes compared to PDS. These results support the transition toward electronic data documentation for the neonatal clinical environment. Electronically linking PCode to the patient database has been initiated and should reduce manual coding errors.

Plasma and urine riboflavin during riboflavin-free nutrition in very-low-birth-weight infants.

BACKGROUND: Very-low-birth-weight (VLBW; birth weight <1500 g) infants receive enteral and parenteral nutriture that provides greater daily riboflavin (vitamin B2) than does term infant nutriture, and elevated plasma riboflavin develops in these infants after birth. The purpose of this study was to measure plasma and urine riboflavin concentrations in VLBW infants during riboflavin-free nutrition. Our hypothesis was that elevated plasma riboflavin develops in VLBW infants because of high daily intake and immature renal riboflavin elimination. METHODS: Eighteen clinically healthy VLBW infants received parenteral nutrition and preterm infant formula during the first postnatal month. On postnatal days 10 and 28, the infants received specially prepared riboflavin-free enteral and parenteral nutrition for the 24-hour study period. Serial collections of plasma were made at time 0 and at 12 and 24 hours. Urine was collected continuously for the 24-hour period in 4-hour aliquots. Samples were analyzed for riboflavin concentration. RESULTS: During the 24-hour riboflavin-free study period on postnatal day 10, plasma riboflavin decreased 56% from 185 +/- 37 ng/mL (mean +/- SEM), and urine riboflavin decreased 75% from 3112 +/- 960 mg/mL. Similarly, on postnatal day 28, plasma riboflavin decreased 79% from 184 +/- 32 ng/mL, and urine riboflavin concentration decreased 91% from 5092 +/- 743 ng/mL during the 24-hour riboflavin-free study period. Riboflavin half-life (t(1/2)) was 18.5 hours on postnatal day 10 and decreased 48% by postnatal day 28. Riboflavin elimination was 145.1 +/- 20.6 mg/kg per day on postnatal day 10 and increased 40% by postnatal day 28. CONCLUSION: The VLBW infants who received parenteral nutrition and preterm infant formula had elevated plasma riboflavin on postnatal days 10 and 28. Plasma riboflavin t(1,2) was shorter and renal riboflavin elimination was greater on postnatal day 28 than on postnatal day 10. Plasma riboflavin was normal after 24 hours of riboflavin-free nutrition. The pattern of plasma and urine riboflavin in VLBW infants suggests a lower daily intake would maintain plasma riboflavin close to normal.

Assessing somatization in functional gastrointestinal disorders: integration of different criteria.

BACKGROUND: Psychiatric assessment of somatization (the tendency to experience and communicate psychological distress in the form of physical symptoms and to seek medical help for them) currently rests on DSM criteria. An alternative diagnostic and conceptual framework has been proposed by an international group of psychosomatic investigators. The aim of this study was to compare these new criteria (Diagnostic Criteria for Psychosomatic Research, DCPR) with DSM-IV in a population where a high prevalence of psychosocial problems is expected (functional gastrointestinal disorders, FGID). METHOD: One hundred and ninety consecutive patients with FGID in a tertiary care center were assessed according to DSM-IV and DCPR criteria. RESULTS: The number of the 12 DCPR diagnoses was almost double that of DSM diagnoses. Only 9% of the patients were not identified by DCPR criteria, whereas this occurred in 25% of patients using DSM criteria. While patients who were given a DSM diagnosis frequently had additional DCPR diagnoses, many patients with DCPR syndromes did not fulfill any DSM criteria. Four DCPR syndromes appared to be particularly frequent and accounted for almost three quarters of the total diagnoses (alexithymia, persistent somatization, functional symptoms secondary to a psychiatric disorder, demoralization). CONCLUSIONS: The joint use of DSM and DCPR criteria was found to improve the identification of psychological factors in FGID. The results may pave the way for changes in DSM classification of somatoform disorders.

Growth in human milk-Fed very low birth weight infants receiving a new human milk fortifier.

BACKGROUND/AIMS: Human milk fortification has been advocated to enhance premature infants' growth. We, therefore, undertook this study of a new human milk fortifier containing more protein than a reference one. METHODS: Open, randomized, controlled, multiclinic trial, with weekly growth parameters and safety evaluations in premature infants <1,500 g. RESULTS: The 2 groups did not differ in demographic and baseline characteristics. The adjusted daily milk intake was significantly higher in the infants fed reference human milk fortifier (n = 29; 154.2 +/- 2.1 vs. 144.4 +/- 2.5 ml/kg/day, mean +/- SE; p < 0.05). Both human milk fortifiers produced increases over baseline in weight, length, and head circumference, with greater gains observed in the new human milk fortifier-fed infants for the former two parameters (weight gain 26.8 +/- 1.3 and 20.4 +/- 1.2 g/day, p < 0.05; head circumference 1.0 +/- 0.1 and 0.8 +/- 0.1 cm/week; length 0.9 +/- 0.1 and 0.8 +/- 0.1 cm/week, respectively). Serum chemistries were normal and acceptable for age. Study events were typical for premature infants and similar in both groups. CONCLUSIONS: This new human milk fortifier had comparable safety to the reference human milk fortifier and promoted faster weight gain and head circumference growth.

A linear regression model to predict the pH of neonatal parenteral nutrition solution.

INTRODUCTION: Providing the high calcium intake necessary for normal bone mineralization in rapidly growing very low birth weight infants is difficult because calcium and phosphorus solubility is limited in the range of parenteral nutrition pH. A major determinant of calcium and phosphorus solubility in vitro is solution pH. The objective of this study was to develop and assess the accuracy of a method to predict the final parenteral solution pH as a linear function of the individual parenteral component concentrations. METHODS: pH values were measured for 205 neonatal parenteral nutrition solutions prepared during a 5-week period. Concentrations of the 13 components used to synthesize parenteral nutrition were determined for each solution. Data from 135 samples were used to develop a linear regression coefficient model with pH as the dependent variable. From the regression model the pH was predicted for the remaining 70 samples using the seven significant solution component concentrations, and the predicted and measured solution pH values were compared. RESULTS: The mean measured parenteral nutrition pH for all solutions was 5.364 +/- 0.110 (mean +/- SD, range 5.03-5.73). The absolute mean pH difference between the predicted and measured value for the 70 test samples was 0.04 +/- 0.04. pH estimated with the model correlated highly with measured pH (r2 = 0.77). The seven components in the regression model accounted for 81% of the pH variance. CONCLUSION: The pH of neonatal parenteral nutrition solutions can be predicted accurately as a linear function of the solution concentrations of the following seven components: sodium acetate, sodium phosphate, potassium phosphate, potassium acetate, magnesium sulphate, amino acid solution and dextrose. The absolute mean difference between measured pH and predicted pH was 0.04. Applying this method to estimate pH with the interactive properties of computer-based ordering systems could enhance calcium and phosphorus administration to very low birth weight infants.

Integration of clinical decision support with on-line encounter documentation for well child care at the point of care.

Electronic medical record systems and clinical practice guideline (CPG) support applications are emerging in the clinical environment to document and support care. Applications which integrate online documentation with CPG are often complex systems bound to a proprietary infrastructure and as such, can be difficult to adapt to changing care guidelines. This paper describes integration of point-of-care clinical documentation to an Internet-based CPG system that was easily modified, utilized available software resources, and separated patient information from CPG. The system combined a text-based encounter documentation tool, Inbox, with a web-based CPG system, SIEGFRIED (System for Interactive Electronic Guidelines with Feedback and Resources for Instructional and Educational Development), which interactively presented care guidelines to providers. Age-specific well child care documentation templates were developed using Inbox for point-of-care documentation. SIEGFRIED contained the knowledge base of child safety education guidelines and executed independent of the program presenting the guidelines. The CPG were accessed from within the documentation template via an Internet hyperlink. Patient chart evaluation indicated that 77% of safety topics were reviewed and 32% of the charts contained documentation indicating all the safety topics were reviewed. Last, routine use of the Inbox-SIEGFRIED system was not realized due to the clinical time constraints and workload of the medical providers, and lack of data entry experience. A user survey indicated time cost (network access and software execution) were negative aspects of the system. However, the system function was highly regarded and the Internet-based patient education materials were described as useful and accurate. In summary, the system was functional, met original development goals, and provided valuable patient education materials; however, routine system use was prevented by time requirements. We recommend further development be oriented towards integrating the identified beneficial components of the system into clinician workflow.

Alexithymia and functional gastrointestinal disorders. A comparison with inflammatory bowel disease.

BACKGROUND: Although the alexithymia construct was derived from observations of patients with classical psychosomatic diseases, empirical studies have found only a moderate association between alexithymia and inflammatory bowel disease (IBD). Indeed, there is some evidence that alexithymia may be associated more strongly with functional somatic symptoms than with the psychosomatic diseases. The present study examined the relationship between alexithymia and functional gastrointestinal disorders (FGIDs) in a group of 121 FGID patients, and compared the results with findings from a group of 116 IBD patients and a group of 112 healthy subjects. METHOD: The subjects completed the 20-item Toronto Alexithymia Scale and the Hospital Anxiety and Depression Scale. RESULTS: The FGID group was significantly more alexithymic than the IBD group, and the two gastrointestinal groups were more alexithymic than the normal healthy group. These differences remained even after controlling for the influence of education, gender, anxiety, depression and gastrointestinal symptoms. CONCLUSIONS: The finding of a high rate of alexithymia (66%) in the group of FGID patients is consistent with the propensity of these patients to somatization and to high levels of poorly differentiated psychological distress.

Evaluation of a long-chain polyunsaturated fatty acid supplemented formula on growth, tolerance, and plasma lipids in preterm infants up to 48 weeks postconceptional age.

BACKGROUND: The last trimester of pregnancy is a period of rapid accretion of long-chain polyunsaturated fatty acids, both in the central nervous system and the body as a whole. Human milk contains these fatty acids, whereas some preterm infant formulas do not. Infants fed formulas without these fatty acids have lower plasma and erythrocyte concentrations than infants fed human milk. Preclinical and clinical studies have demonstrated that single-cell sources (algal and fungal) of long-chain polyunsaturated fatty acids are bioavailable. A balanced addition of fatty acids from these oils to preterm formula results in blood fatty acid concentrations in low birth weight infants comparable to those of infants fed human milk. METHODS: In the present study the growth, acceptance (overall incidence of discontinuation, reasons for discontinuation, overall incidence and type of individual adverse events), and plasma fatty acid concentrations were compared in three groups of infants fed a long-chain polyunsaturated fatty acid-supplemented preterm infant formula, an unsupplemented control formula, or human milk. The study was prospective, double-blind (formula groups only), and randomized (formula groups only). Two hundred eighty-eight infants were enrolled (supplemented formula group, n = 77; control formula group, n = 78; human milk group, n = 133). RESULTS: Anthropometric measurements at enrollment, at first day of full oral feeding, and at both 40 and 48 weeks postconceptional age did not differ between the formula groups, whereas the human milk-fed group initially grew at a lower rate. The incidence of severe adverse events was rare and not significantly different between formula groups. The groups fed either human milk or supplemented formula had long-chain polyunsaturated fatty acid concentrations higher than those in the control formula group. CONCLUSIONS: The results of this study demonstrate the safety and efficacy of a preterm formula supplemented with long-chain polyunsaturated fatty acids from single-cell oils.
