Long-term nutritional outcome after pediatric intestinal transplantation.

BACKGROUND/PURPOSE: The aim of this study was to describe the long-term nutritional status of a large population of children after intestinal transplantation and to identify factors associated with nutritional outcomes. METHODS: Longitudinal anthropometric data are maintained in a database registry for all patients referred to our Intestinal Care Center (ICC). Z-scores for weight and height were calculated biannually over a maximum of 2 years, and associations between baseline and follow-up laboratory measures and growth were evaluated for patients greater than 6 months post intestinal transplant. RESULTS: Since the inception of the ICC in December 1996, 24 pediatric patients (18 boys, 18 white) received an isolated small bowel or small bowel/liver transplant (median age, 3.2 years). The majority of cases (75%) had been diagnosed with surgical short bowel syndrome and were dependent on total parenteral nutrition (TPN) at the time of transplant. Of the 23 patients who survived the initial postoperative period, 87% were weaned from TPN to an amino-acid or peptide-based enteral formula or solid food within 3 months. A positive trend in z-scores for weight and height/length was observed in only 30% and 26% of patients, respectively, during the follow-up period. Although mean albumin levels increased significantly from 2.8 to 3.1 mg/dl by 6 months posttransplant (P <.01) no difference in alkaline phosphatase was found over time. Steroid doses were weaned within 3 to 4 months after transplantation but not discontinued. The cumulative survival rate was 91% at 1 year and 86% at 2 years posttransplant, whereas those weaned from TPN achieved 100% and 94% survival, respectively. CONCLUSIONS: Attainment of positive linear growth remains a challenge in the pediatric transplant population despite successful liberation from TPN, protein anabolism, and high survival rates. Further investigation into alternative methods of nutritional evaluation and manipulation as well as the use of growth factors to enhance the growth process need to be investigated.

A review of randomized controlled trials using therapeutic apheresis.

Apheresis has developed into a common therapeutic modality. The evidence for the clinical benefit of apheresis, however, is generally from uncontrolled and nonrandomized trials. Although the effectiveness of therapeutic apheresis may be established from uncontrolled trials, well-designed, randomized controlled trials provide the best evidence for a clinical benefit because this type of trial design minimizes bias. We assess the evidence for the use of apheresis, the optimal schedules for apheresis, and the replacement solutions used, based on randomized controlled trials. The databases, MEDLINE and EMBASE, and reference lists from relevant articles were searched. The literature search was restricted to articles published in English and included adult patients only. Two of the authors (NS, CK) independently reviewed the citation list to identify reports for retrieval, and the kappa statistic was used to quantify agreement between the reviewers. Articles were included if they used apheresis as an intervention and had clinical endpoints. The quality of the studies was assessed by using a validated instrument. Five hundred and ninety-two citations were identified, and a total of 85 reports were included in this review. There are only a few well-established indications for therapeutic apheresis. Randomized, controlled trials have clearly shown a benefit for patients treated with apheresis who have Guillain-Barre syndrome and patients who have thrombotic thrombocytopenic purpura. A clinical benefit has not been shown for a variety of conditions, including systematic lupus erythematosus, polyarteritis nodosa/Churg-Strauss syndrome, and for the treatment of renal allograft rejection. The effectiveness of apheresis needs to be clarified for several other diseases. As better-designed, randomized trials are performed, the role of apheresis for these indications will be further elucidated.

Breast-feeding and the onset of atopic dermatitis in childhood: a systematic review and meta-analysis of prospective studies.

BACKGROUND: Despite the numerous studies on the possible protective effect of breast-feeding against the onset of atopic dermatitis during childhood, this issue remains controversial. OBJECTIVE: We conducted a systematic review with meta-analysis of prospective studies that evaluated the association between exclusive breast-feeding during the first 3 months after birth and atopic dermatitis. METHODS: A comprehensive search of the 1966-2000 MEDLINE database and review of the reference lists of relevant articles identified 18 prospective studies that met the predefined inclusion criteria. By means of a standardized approach, 2 of the investigators independently assessed the methodologic quality of the studies, duration and exclusivity of breast-feeding, outcome measures, and control for potential confounding factors. The same approach was applied during data abstraction and evaluation of the estimates of association. Summary measures of association were then calculated. RESULTS: The summary odds ratio (OR) for the protective effect of breast-feeding in the studies analyzed was 0.68 (95% confidence interval [CI], 0.52-0.88). This effect estimate was higher in the group of studies wherein children with a family history of atopy were investigated separately (OR = 0.58; CI, 0.41-0.92) than in those of combined populations (OR = 0.84; CI, 0.59-1.19). A small subset of studies of children without a history of atopy in first-degree relatives showed no association between breast-feeding and the onset of atopic dermatitis (OR = 1.43; CI, 0.72-2.86). CONCLUSION: Exclusive breast-feeding during the first 3 months of life is associated with lower incidence rates of atopic dermatitis during childhood in children with a family history of atopy. This effect is lessened in the general population and negligible in children without first-order atopic relatives. Breast-feeding should be strongly recommended to mothers of infants with a family history of atopy, as a possible means of preventing atopic eczema.

Vitamin A supplementation and childhood morbidity from diarrhea and respiratory infections: a meta-analysis.

OBJECTIVES: To perform an updated meta-analysis of the effect of vitamin A supplementation on childhood morbidity from respiratory tract infections and diarrhea. Study design A comprehensive search of the 1966 to 2000 MEDLINE database and review of the reference lists of relevant articles identified 9 randomized controlled trials dealing with morbidity from respiratory infections and diarrhea in children 6 months to 7 years of age and provided "intention-to-treat" data. RESULTS: The combined results indicated that vitamin A supplementation has no consistent overall protective effect on the incidence of diarrhea (relative risk, 1.00; 95% CI, 0.94-1.07) and that it slightly increases the incidence of respiratory tract infections (relative risk, 1.08; 95% CI, 1.05-1.11). CONCLUSIONS: High-dose vitamin A supplements are not recommended on a routine basis for all preschool children and should be offered only to individuals or populations with vitamin A deficiency.

Nonsaphenous superficial vein reflux.

BACKGROUND: Information on nonsaphenous superficial venous reflux is lacking. This study was designed to determine the prevalence of reflux in nonsaphenous veins, their association and correlation with risk factors, and signs and symptoms of chronic venous disease (CVD). METHODS: Information on 835 limbs in patients with signs and symptoms of CVD were prospectively entered into a customized database. These patients had been referred from the venous clinic to the vascular laboratory for color-flow duplex scanning evaluation of the lower-limb veins. All patients were examined for reflux in the standing and sitting positions. Nonsaphenous reflux was defined as that in superficial veins that are not part of the greater or lesser saphenous systems. Particular attention was paid to the patterns of reflux and anatomy of the nonsaphenous veins from the proximal to the distal ends, including their connections with the saphenous and deep veins. RESULTS: Nonsaphenous venous reflux was found in 84 limbs (10%) of 72 patients, 67 of whom were women. The mean number of pregnancies in these patients was higher than that of 100 randomly selected women with saphenous reflux (3.2 vs 2.2). According to CEAP classification, 90% of the limbs were in CVD classes 1 through 3 and only 10% had skin damage (classes 4-6). Symptoms were present in 67 limbs (80%). Forty-two limbs (50%) had reflux in tributaries of lateral, posterior, and medial thigh. These veins were connected with perforators uniting with the deep femoral, femoral, and muscular veins of the thigh in 36 limbs. Reflux in these perforators was detected in 19 limbs. Reflux arising from the pelvic veins was found in 29 limbs (34%), 18 of which were from vulvar veins medial to saphenofemoral junction and 11 of which were from veins in the gluteal area. Incompetent veins from the sciatic nerve were found in nine limbs (10%). Reflux in the vein of the popliteal fossa was found in seven limbs (8%). Reflux in knee tributaries was detected in three limbs (4%), two of which were connected with posterolateral knee perforators and one with the posterior tibial nerve veins. CONCLUSIONS: The prevalence of nonsaphenous reflux in our practice was 10%. The vast majority of these patients (93%) were women with a mean of 3.2 pregnancies. Ninety percent of these limbs have signs and symptoms assigned to CVD classes 1 to 3. These data may simply reflect the referral pattern, but also a possible association with female sex and number of pregnancies. The unusual anatomy of these veins stresses the importance of color-flow duplex scanning before surgery.

Gender and blindness: a meta-analysis of population-based prevalence surveys.

BACKGROUND: Many individual surveys of blindness have reported slightly higher rates of blindness for women. In order to gain a continent-by-continent and global sense of the burden of blindness by sex we conducted a meta-analysis of published, population-based surveys of blindness. METHOD: Published reports were collected using a predetermined search protocol involving commercial electronic databases, hand-searching of references and direct contact with researchers. Studies were included that were population-based, included clinical examination and had a minimum sample size of 1000. The studies were critically appraised to determine methodological rigour. Data were analysed using the Cochrane Collaboration Review Manager. RESULTS: The overall odds ratio (age-adjusted) of blind women to men is 1.43 (95% CI 1.33-1.53), ranging from 1.39 (95% CI 1.20-1.61) in Africa, 1.41 (95% CI 1.29-1.54) in Asia, and 1.63 (95% CI 1.30-2.05) in industrialised countries. There was good homogeneity of findings from Africa, Asia, and the industrialised countries. Globally, women bear excess blindness compared to men. In these surveys, overall, women account for 64.5% of all blind people. The excess of blindness in women was marked among the elderly and not due only to differential life expectancy. CONCLUSION: The excess burden of blindness among women is likely due to a number of factors, which are different in industrialised countries compared to developing countries. Particular attention to gender differences in blindness is needed in the creation of targets for blindness reduction and in the development of interventions.

Does breastfeeding protect against allergic rhinitis during childhood? A meta-analysis of prospective studies.

UNLABELLED: The effect of breastfeeding on the development of allergic rhinitis and other atopic conditions has been assessed in many studies but remains controversial. To elucidate this issue, a systematic review was conducted of prospective studies that evaluated the association between exclusive breastfeeding during the first 3 mo after birth and allergic rhinitis. The 1966-2000 MEDLINE databases were searched and the reference lists of relevant articles were reviewed according to predetermined inclusion criteria. The methodological aspects of each study, duration and exclusivity of breastfeeding, outcome measures, control for potential confounding variables and other factors were assessed, and estimates of the association between breastfeeding and allergic rhinitis were abstracted independently by the investigators using a standardized approach. Six prospective studies met the inclusion criteria. The summary odds ratio for the protective effect of breastfeeding was 0.74 (95% confidence interval 0.54-1.01). The effect estimate in studies of children with a family history of atopy was 0.87 (95% confidence interval 0.48-1.58). CONCLUSION: Exclusive breastfeeding during the first 3 mo after birth protects against allergic rhinitis in children, both with and without a family history of atopy. The protective association, although of borderline statistical significance, was substantial. Larger prospective studies with strict methodology and longer periods of follow-up are needed.

Do geriatric interventions reduce emergency department visits? A systematic review.

BACKGROUND: Hospital emergency departments (EDs) serve an aging population with an increased burden on health resources. Few studies have examined the effects of comprehensive geriatric assessment interventions on ED use. This study aimed to systematically review the literature and compare the effects of these interventions on ED visits. METHODS: Relevant articles were identified through electronic databases and a search of reference lists and personal files. Inclusion criteria included: original research (written in English or French) on interventions conducted in noninstitutionalized populations 60 years old or older, not restricted to a particular medical condition, in which ED visits were a study outcome. Data were abstracted and checked by the first author and a research assistant using a standard protocol. RESULTS: Twenty-six relevant studies were identified, reported in 28 articles, with study samples obtained from EDs (9), hospitals (4), outpatient or primary care settings (10), home care (4), and community (1). The study designs included 17 randomized controlled trials, 3 trials with nonrandom allocation, 4 before-after studies, 1 quasi-experimental time-series study, and 1 cross-sectional study. Hospital-based interventions (mostly short-term assessment and/or liaison) had little overall effect on ED utilization, whereas many interventions in outpatient and/or primary care or home care settings (including geriatric assessment and management and case management) reduced ED utilization. Heterogeneity in study methods, measures of comorbidity, functional status, and ED utilization precluded meta-analysis of the results. CONCLUSION: Further research, using improved methodologies and standardized measures, is needed to address the effects of innovative geriatric interventions on ED visits.

Issues of race, ethnicity, and culture in caregiving research: a 20-year review (1980-2000).

PURPOSE: The goals of this review are to synthesize what is known about caregiving among diverse groups and to identify gaps in knowledge to guide future research on caregiving. The review focuses on conceptual and theoretical approaches, sampling strategies, measurement techniques, and similarities and differences found among groups and across studies. DESIGN AND METHODS: A narrative approach was used to review 59 articles published between 1980 and 2000, with particular attention to race, ethnicity, and/or culture. Primary sources of relevant articles included electronic databases, other review articles, and reference lists. RESULTS: Caregiving experiences and outcomes varied across racial and ethnic groups. However, the use of nontheoretical approaches, nonprobability samples, and inconsistent measures among studies has limited understanding of caregiving among diverse populations. IMPLICATIONS: It is important that conceptualization and theorizing broaden with increasing numbers of studies that include diverse groups. Future caregiving research needs to give more attention to such issues as acculturation, assimilation, and cultural values, beliefs, and norms, while also improving theoretical and methodological rigor.

Consolidation therapy with autologous bone marrow transplantation in adults with acute myeloid leukemia: a meta-analysis.

BACKGROUND: The optimal consolidation therapy for adults who are in first remission of acute myeloid leukemia after induction chemotherapy and who do not have a histocompatible donor is poorly established. We conducted a meta-analysis to compare the efficacy of autologous bone marrow transplantation with that of non-myeloablative chemotherapy alone (or no further treatment). METHODS: Eligible studies were identified by searching electronic databases and by examining the reference lists of relevant studies and review articles. Eligible studies were those that prospectively enrolled adults with acute myeloid leukemia and randomly assigned patients who were in first remission and who did not have a matched sibling donor to one of the two consolidation therapies. Two reviewers independently assessed all studies for relevance and validity. We used a fixed-effects model to calculate the ratio of probabilities for disease-free and overall survival at 48 months or at the nearest recorded assessment point for each study and for all studies combined. All statistical tests were two-sided. RESULTS: We identified 587 potentially relevant studies, 36 of which were retrieved for detailed evaluation. In the six studies eligible for this meta-analysis, a total of 1044 patients were randomly assigned to receive autologous bone marrow transplantation or non-myeloablative chemotherapy (five studies) or autologous bone marrow transplantation or no further treatment (one study). Compared with patients who received chemotherapy or no further treatment, patients who received autologous bone marrow transplantation had a better disease-free survival (ratio of disease-free survival probabilities = 1.24, 95% confidence interval [CI] = 1.06 to 1.44; P =.006) but a similar overall survival (ratio of overall survival probabilities = 1.01, 95% CI = 0.89 to 1.15; P =.86). CONCLUSION: Our results do not support the routine use of autologous bone marrow transplantation in adult acute myeloid leukemia patients in first remission.

The use of focus group interviews in pediatric health care research.

OBJECTIVE: To review and synethize the research material on focus groups with children and adolescents and to provide guidelines for future development. METHODS: Psychlit, Medline, and Cinahl electronic databases, as well as the reference lists of those articles consulted, were reviewed for information regarding focus groups with participants under the age of 18 years. Both empirical and methodological articles were part of this review. RESULTS: We review the utility of focus groups for exploratory research, program evaluation, program development, and questionnaire construction or adaptation. Based on previous research, we provide guidelines for focus groups with children and adolescents and outline suggestions for future development. CONCLUSIONS: There is evidence to suggest that focus groups are a valuable means of eliciting children's views on health-related matters, given an appropriate research question. However, empirical research is required in order to investigate systematically the effect of different processes and variables on the final outcome of focus group interviews.

Comparative efficacy and safety of ondansetron, droperidol, and metoclopramide for preventing postoperative nausea and vomiting: a meta-analysis.

UNLABELLED: Postoperative nausea and vomiting are important causes of morbidity after anesthesia and surgery. We performed a meta-analysis of published, randomized, controlled trials to determine the relative efficacy and safety of ondansetron, droperidol, and metoclopramide for the prevention of postoperative nausea and vomiting. We performed a literature search of English references using both the MEDLINE database and a manual search. Double-blinded, randomized, controlled trials comparing the efficiency of the prophylactic administration of ondansetron, droperidol, and/or metoclopramide therapy during general anesthesia were included. A total of 58 studies were identified, of which 4 were excluded for methodological concerns. For each comparison of drugs, a pooled odds ratio (OR) with a 95% CI was calculated using a random effects model. Ondansetron (pooled OR 0.43, 95% CI 0.31, 0.61; P < 0.001) and droperidol (pooled OR 0.68, 95% CI 0.54, 0.85; P < 0.001) were more effective than metoclopramide in preventing vomiting. Ondansetron was more effective than droperidol in preventing vomiting in children (pooled OR 0.49; P = 0.004), but they were equally effective in adults (pooled OR 0.87; P = 0.45). The overall risk of adverse effects was not different among drug combinations. We conclude that ondansetron and droperidol are more effective than metoclopramide in reducing postoperative vomiting. IMPLICATIONS: We performed a systematic review of published, randomized, controlled trials to determine the relative efficacy and safety of ondansetron, droperidol, and metoclopramide for preventing postoperative nausea and vomiting. Ondansetron and droperidol were more effective than metoclopramide in reducing postoperative vomiting. The overall risk of adverse effects did not differ.

Thrombolysis during cardiopulmonary resuscitation in fulminant pulmonary embolism: a review.

OBJECTIVE: To review current knowledge on thrombolysis in patients with fulminant pulmonary embolism (FPE) who need cardiopulmonary resuscitation (CPR). DATA SOURCES: The bibliography for the study was compiled through a search of different databases between 1966 and 2000. References cited in the articles selected were also reviewed. STUDY SELECTION: The selection criteria included all reports published on thrombolysis, pulmonary embolism, and CPR, from case reports and case series to controlled studies. DATA SYNTHESIS: Very few studies evaluated thrombolysis in cases of FPE that required CPR and most of these were clinical case reports and case series with a low level of scientific evidence. There has been no clinical trial to address this issue. CONCLUSIONS: FPE can frequently produce cardiac arrest, which has an extremely high mortality despite application of the usual CPR measures. The administration of thrombolytic therapy during CPR could help to reduce the mortality, although it has classically been contraindicated. There are no published clinical trials or other high-grade studies that evaluated the efficacy and safety of this approach. From the few existing studies, it can be inferred that thrombolysis may be efficacious and safe for patients with FPE who need CPR. However, a clinical trial is required to provide evidence of value for sound clinical decision-making.

Dorsal root entry zone lesioning used to treat central neuropathic pain in patients with traumatic spinal cord injury: a systematic review.

STUDY DESIGN: A systematic review was conducted for studies of any design. OBJECTIVES: To evaluate the effectiveness and safety of dorsal root entry zone lesioning in treating central neuropathic pain of patients with traumatic spinal cord injury. SUMMARY OF BACKGROUND DATA: Central neuropathic pain has a great impact on the quality of life of many patients with traumatic spinal cord injury. Dorsal root entry zone lesioning has become one of several treatment options. No previous systematic reviews were found that address this indication for the procedure. METHODS: Several computerized databases were searched along with reference lists of eligible articles and personal files of advisory panel members. Only primary studies of patients older than 13 years with both traumatic spinal cord injury and central neuropathic pain receiving dorsal root entry zone lesioning were included. Two assessors independently performed data extraction and quality assessment for all the studies. RESULTS: The selection criteria were met by 11 studies. All were case series of 5 to 54 patients. As reported by 10 of the studies, at least 50% of the patients attained more than 50% pain relief or experienced no pain limitation of activity and no need for narcotics. However, all the studies had poorly defined eligibility criteria or none at all, no control groups, and inadequate reporting of adverse effects. Only one study provided adequate patient description. None of the studies reported the validity, reliability, or responsiveness of outcome measures. CONCLUSIONS: Reviewed studies indicate promising results from dorsal root entry zone lesioning for the treatment of central neuropathic pain in selected patients with traumatic spinal cord injury. However, the strength of the evidence provided by the studies was poor in terms of study design, outcome measures, reports on the severity of adverse effects, patient selection criteria, and patient description. For these reasons, the evidence is weak for the use of dorsal root entry zone lesioning to relieve central neuropathic pain in patients with traumatic spinal cord injury.

Cost-effectiveness of therapeutic drug monitoring: a systematic review.

There are a number of effective but highly toxic drugs that exhibit a narrow therapeutic index and marked interpatient pharmacokinetic variability. Individualized therapy with such drugs requires therapeutic drug monitoring (TDM) to obtain the desired clinical effects safely. Cost-effectiveness analysis in health care is still at an early stage of development, especially for TDM. A systematic review was carried out to document studies that have addressed the cost-effectiveness of TDM. The Cochrane database and Medline were searched. References identified by this approach were then searched manually for relevant articles. Very few studies have been performed that document the cost-effectiveness of TDM, and TDM has been demonstrated to be cost-effective only for aminoglycosides. For the other classes of drugs that are monitored, the rationale for TDM has been supported, but appropriate cost-effectiveness analyses have not been performed. Because the use of many of these drugs without TDM would increase the risk of under- or overdosing, emphasis should not be placed solely on cost-effectiveness but rather on how such interventions can be applied in the most cost-effective and clinically useful manner.

The effectiveness of worksite physical activity programs on physical activity, physical fitness, and health.

OBJECTIVE: To critically review the literature with respect to the effectiveness of worksite physical activity programs on physical activity, physical fitness, and health. DATA SOURCES: A search for relevant English-written papers published between 1980 and 2000 was conducted using MEDLINE, EMBASE, Sportdiscus, CINAHL, and Psychlit. The key words used involved a combination of concepts regarding type of study, study population, intervention, and outcome measure. In addition, a search was performed in our personal databases, as well as a reference search of the studies retrieved. STUDY SELECTION: The following criteria for inclusion were used: 1) randomized, controlled trial or nonrandomized, controlled trial; 2) working population; 3) worksite intervention program to promote employees' physical activity or physical fitness; and 4) physical activity, physical fitness, or health-related outcomes. DATA EXTRACTION: Two reviewers independently evaluated the quality of relevant studies using a predefined set of nine methodological criteria. Conclusions regarding the effectiveness of a worksite physical activity programs were based on a rating system consisting of five levels of evidence. DATA SYNTHESIS: Fifteen randomized, controlled trials and 11 nonrandomized, controlled trials met the criteria for inclusion and were reviewed. Six randomized, controlled trials and none of the nonrandomized, controlled trials were of high methodological quality. Strong evidence was found for a positive effect of a worksite physical activity program on physical activity and musculoskeletal disorders. Limited evidence was found for a positive effect on fatigue. For physical fitness, general health, blood serum lipids, and blood pressure, inconclusive or no evidence was found for a positive effect. CONCLUSIONS: To increase the level of physical activity and to reduce the risk of musculoskeletal disorders, we support implementation of worksite physical activity programs. For the other outcome measures, scientific evidence of the effectiveness of such a program is still limited or inconclusive, which is mainly the result of the small number of high-quality trials. Therefore, we recommend performing more randomized, controlled trials of high methodological quality, taking into account criteria such as randomization, blinding, and compliance.

Atraumatic cardiac arrest in apparently healthy young women.

Sudden non-traumatic death in young people (< 30 years old) has been discussed both in systematic studies and anecdotal reports. After presenting three remarkable cases, a global survey of the incidence with special reference to the Belgian CPCR database, ethiopathogenesis and prognosis of sudden non-traumatic death in this specific age group is given. The atherosclerotic coronary artery disease (CAD) related and especially the non-CAD related causes are extensively discussed as well as the role of intoxication and increasing drug and substance abuse. After conventional cardiopulmonary resuscitation with restoration of spontaneous circulation and a favourable neurological outcome, a thorough search for the underlying disease is mandatory. The involvement of drugs or other toxins has to be excluded in the first place. Apart from transoesophageal echocardiography and coronary angiography, electrophysiological testing, serological exams, myocardial biopsy and magnetic resonance imaging should be considered.
