Effects of live-online, group mindfulness training on opioid use and anxiety during buprenorphine treatment: A comparative effectiveness RCT. Contemp Clin Trials 2024; 137:107417. [PMID: 38135210 DOI: 10.1016/j.cct.2023.107417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 11/24/2023] [Accepted: 12/17/2023] [Indexed: 12/24/2023]
Abstract
BACKGROUND Office-based opioid treatment with buprenorphine has emerged as a popular evidence-based treatment for opioid use disorder. Unfortunately, psychosocial stress, anxiety, pain, and co-morbid substance use increase patients' risk for relapse. We designed this study to compare the effects of complementing buprenorphine treatment with 24 weeks of a live-online Mindful Recovery Opioid Care Continuum (M-ROCC) group to a time and attention-matched, live-online Recovery Support Group (RSG) active control condition. METHODS We plan to enroll a maximum of N = 280 and randomize at least N = 192 patients prescribed buprenorphine through referrals from office-based and telemedicine buprenorphine treatment providers and social media advertisements. Participants will be randomly assigned to M-ROCC or RSG and will be blinded to their treatment condition. The primary outcome for this study will be biochemically confirmed periods of abstinence from illicit opioids, as measured by self-reported use and randomly collected, video-observed oral fluid toxicology testing during the final 12 weeks of study participation. Secondary outcomes include changes in Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety and pain interference scores between baseline and week 24. RESULTS The trial was funded by the National Institutes of Health, HEAL Initiative through NCCIH (R33AT010125). Data collection is projected to end by September 2023, and we expect publication of results in 2024. CONCLUSION If the M-ROCC intervention is found to be effective in this format, it will demonstrate that live-online mindfulness groups can improve outcomes and address common co-morbidities like anxiety and pain during buprenorphine treatment.

Abstract
BACKGROUND AND OBJECTIVES Family physicians are well positioned to treat patients with substance use disorders (SUDs), expand access to care, destigmatize addiction, and provide a biopsychosocial treatment approach. There is a great need to train residents and faculty to competency in SUD treatment. Through the Society of Teachers of Family Medicine (STFM) Addiction Collaborative, we created and evaluated the first national family medicine (FM) addiction curriculum using evidence-based content and teaching principles. METHODS After launching the curriculum with 25 FM residency programs, we collected formative feedback through monthly faculty development sessions and summative feedback through 8 focus groups with 33 faculty members and 21 residents. We used qualitative thematic analysis to assess the value of the curriculum. RESULTS The curriculum enriched resident and faculty knowledge across all SUD topics. It changed their attitudes in viewing addiction as a chronic disease within the scope of FM practice, increased confidence, and decreased stigma. It nurtured behavior change, enhancing communication and assessment skills and encouraging collaboration across disciplines. Participants valued the flipped-classroom approach, videos, cases, role plays, ready-made teacher's guides, and one-page summaries. Having protected time to complete the modules and temporally coupling the modules with the live, faculty-led sessions enhanced learning. CONCLUSION The curriculum provides a comprehensive, ready-made, evidenced-based platform for training residents and faculty in SUDs. It can be implemented by faculty with all levels of prior expertise, cotaught by physicians and behavioral health providers, tailored to each program's didactic schedule, and modified based on the local culture and resource availability.

"Virtual patch clamp analysis" for predicting the functional significance of pathogenic variants in sodium channels. Epilepsy Res 2022; 186:107002. [PMID: 36027690 DOI: 10.1016/j.eplepsyres.2022.107002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 07/28/2022] [Accepted: 08/11/2022] [Indexed: 11/03/2022]
Abstract
OBJECTIVE Opening of voltage-gated sodium channels is crucial for neuronal depolarization. Proper channel opening and influx of Na+ through the ion pore, is dependent upon binding of Na+ ion to a specific amino-acid motif (DEKA) within the pore. In this study we used molecular dynamic simulations, an advanced bioinformatic tool, to research the dysfunction caused by pathogenic variants in SCN1a, SCN2a and SCN8a genes. METHOD Molecular dynamic simulations were performed in six patients: three patients with Dravet syndrome (p.Gly177Ala,p.Ser259Arg and p.Met1267Ile, SCN1a), two patients with early onset drug resistant epilepsy(p.Ala263Val, SCN2a and p.Ile251Arg, SCN8a), and a patient with autism (p.Thr155Ala, SCN2a). After predicting the 3D-structure of mutated proteins by homology modeling, time dependent molecular dynamic simulations were performed, using the Schrödinger algorithm. The opening of the sodium channel, including the detachment of the sodium ion to the DEKA motif and pore diameter were assessed. Results were compared to the existent patch clamp analysis in four patients, and consistency with clinical phenotype was noted. RESULTS The Na+ ion remained attached to DEKA filter longer when compared to wild type in the p.Gly177Ala, p.Ser259Arg,SCN1a, and p.Thr155Ala, SCN2a variants, consistent with loss-of-function. In contrast, it detached quicker from DEKA than wild type in the p.Ala263Val,SCN2a variant, consistent with gain-of-function. In the p.Met1267Ile,SCN1a variant, detachment from DEKA was quicker, but pore diameter decreased, suggesting partial loss-of-function. In the p.Leu251Arg,SCN8a variant, the pore remained opened longer when compared to wild type, consistent with a gain-of-function. The molecular dynamic simulation results were consistent with the existing patch-clamp analysis studies, as well as the clinical phenotype. SIGNIFICANCE Molecular dynamic simulation can be useful in predicting pathogenicity of variants and the disease phenotype, and selecting targeted treatment based on channel dysfunction. Further development of these bioinformatic tools may lead to "virtual patch-clamp analysis".

Abstract
In March 2019, our health system launched a project called Linking MATTERS (Medication for Addiction Treatment linkage Through Emergency depaRtmentS) to initiate evidence-based treatment for opioid use disorder (OUD) with buprenorphine-naloxone (B/N) in our emergency departments and connect patients to our primary care sites to continue their addiction care. Methods: Six months after project implementation, we conducted in-depth interviews with frontline providers (n = 14), including emergency physicians and hospitalists, recovery coaches, ED and outpatient nurses, and case managers. We used qualitative thematic analysis to identify barriers and facilitators to implementation and suggestions for improving the project. Results: We identified five salient themes: (1) provider trainings: mandated, rather than optional trainings, facilitated provider uptake; (2) provider attitudes: there was a growing recognition of addiction as a chronic, medical disease and the value of B/N in supporting patients' recovery, driven by a desire to make a difference in patients' lives; (3) patient engagement: frontline providers with lived experience of addiction who had designated time (such as recovery coaches) were optimally positioned to engage patients; (4) the linking mechanism: personal connections between ED and outpatient providers, rather than follow-up telephone calls, facilitated linkage; and (5) suggestions for improving the program, including: a physical space/bridge clinic to provide patient linkage, expansion of the recovery coach program, and standardized, evidence-based interdisciplinary trainings for all frontline providers. Conclusion: The insights provided will support further program modifications. Healthcare systems should explore whether the components we identified warrant attention locally based on their unique infrastructure and culture.

Building a Group-Based Opioid Treatment (GBOT) blueprint: a qualitative study delineating GBOT implementation. Addict Sci Clin Pract 2019; 14:47. [PMID: 31882001 PMCID: PMC6935085 DOI: 10.1186/s13722-019-0176-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2019] [Accepted: 12/11/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Group-Based Opioid Treatment (GBOT) has recently emerged as a mechanism for treating patients with opioid use disorder (OUD) in the outpatient setting. However, the more practical "how to" components of successfully delivering GBOT has received little attention in the medical literature, potentially limiting its widespread implementation and utilization. Building on a previous case series, this paper delineates the key components to implementing GBOT by asking: (a) What are the core components to GBOT implementation, and how are they defined? (b) What are the malleable components to GBOT implementation, and what conceptual framework should providers use in determining how to apply these components for effective delivery in their unique clinical environment? METHODS To create a blueprint delineating GBOT implementation, we integrated findings from a previously conducted and separately published systematic review of existing GBOT studies, conducted additional literature review, reviewed best practice recommendations and policies related to GBOT and organizational frameworks for implementing health systems change. We triangulated this data with a qualitative thematic analysis from 5 individual interviews and 2 focus groups representing leaders from 5 different GBOT programs across our institution to identify the key components to GBOT implementation, distinguish "core" and "malleable" components, and provide a conceptual framework for considering various options for implementing the malleable components. RESULTS We identified 6 core components to GBOT implementation that optimize clinical outcomes, comply with mandatory policies and regulations, ensure patient and staff safety, and promote sustainability in delivery. These included consistent group expectations, team-based approach to care, safe and confidential space, billing compliance, regular monitoring, and regular patient participation. We identified 14 malleable components and developed a novel conceptual framework that providers can apply when deciding how to employ each malleable component that considers empirical, theoretical and practical dimensions. CONCLUSION While further research on the effectiveness of GBOT and its individual implementation components is needed, the blueprint outlined here provides an initial framework to help office-based opioid treatment sites implement a successful GBOT approach and hence potentially serve as future study sites to establish efficacy of the model. This blueprint can also be used to continuously monitor how components of GBOT influence treatment outcomes, providing an empirical framework for the ongoing process of refining implementation strategies.

Abstract
Background: Group-based models of Office-Based Opioid Treatment with buprenorphine-naloxone (B/N) are increasingly being implemented in clinical practice to increase access to care and provide additional therapeutic benefits. While previous studies reported these Group-Based Opioid Treatment (GBOT) models are feasible for providers and acceptable to patients, there has been no literature to help providers with the more practical aspects of how to create and maintain GBOT in different outpatient settings. Case series: We present 4 cases of GBOT implementation across a large academic health care system, highlighting various potential approaches for providers who seek to implement GBOT and demonstrate "success" based on feasibility and sustainability of these models. For each case, we describe the pros and cons and detail the personnel and resources involved, patient mix and group format, workflow logistics, monitoring and management, and sustainability components. Discussion: The implementation details illustrate that there is no one-size-fits-all approach, although feasibility is commonly supported by a team-based, patient-centered medical home. This approach includes the capacity for referral to higher levels of mental health and addiction support services and is bolstered by ongoing provider communication and shared resources across the health system. Future research identifying the core and malleable components to implementation, their evidence base, and how they might be influenced by site-specific resources, culture, and other contextual factors can help providers better understand how to implement a GBOT model in their unique clinical environment.

Abstract
BACKGROUND Primary care providers are well positioned to respond to the opioid crisis by providing buprenorphine/naloxone (B/N) through shared medical appointments (SMAs). Although quantitative research has been previously conducted on SMAs with B/N, the authors conducted a qualitative assessment from the patients' point of view, considering whether and how group visits provide value for patients. METHODS Twenty-five participants with opioid use disorder (OUD) who were enrolled in a weekly B/N group visit at a family medicine clinic participated in either of two 1-hour-long focus groups, which were conducted as actual group visits. Participants were prompted with the question "How has this group changed you as a person?" Data were audio-recorded and professionally transcribed and analyzed using a qualitative thematic approach, identifying common communication behaviors and resulting attitudes about the value of the group visit model. RESULTS Participants demonstrated several communication behaviors that support group members in their recovery, including offering direct emotional support to others struggling with difficult experiences, making an intentional effort to probe about others' lives, venting about heavy situations, joking to lighten the mood, and expressing feelings of gratitude to the entire group. These communication behaviors appear to act as mechanisms to foster a sense of accountability, a shared identity, and a supportive community. Other demonstrated group behaviors may detract from the value of the group experience, including side conversations, tangential comments, and individual participants disproportionately dominating group time. CONCLUSION The group visit format for delivering B/N promotes group-specific communication behaviors that may add unique value in supporting patients in their recovery. Future research should elucidate whether these benefits can be isolated from those achieved solely through medication treatment with B/N and if similar benefits could be achieved in non-primary care sites.

Abstract
Biliary atresia (BA) is a rare but potentially devastating disease. The European Biliary Atresia Registry (EBAR) was set up to improve data collection and to develop a pan-national and interdisciplinary strategy to improve clinical outcomes. From 2001 to 2005, 100 centers from 22 countries registered with EBAR via its website (www.biliary-atresia.com). In June 2006, the first meeting was held to evaluate results and launch further initiatives. During a 5-year period, 60 centers from 19 European countries and Israel sent completed registration forms for a total of 514 BA patients. Assuming the estimated incidence of BA in Europe is 1:18,000 live births, 35% of the expected 1488 patients from all EBAR participating countries were captured, suggesting that reporting arrangements need improvement. At the meeting, the cumulative evaluation of 928 BA patients including patients from other registries with variable follow-up revealed an overall survival of 78% (range from 41% to 92%), of whom 342 patients (37%) have had liver transplants. Survival with native liver ranged from 14% to 75%. There was a marked variance in reported management and outcome by country (e.g., referral patterns, timing of surgery, centralization of surgery). In conclusion, EBAR represents the first attempt at an overall evaluation of the outcome of BA from a pan-European perspective. The natural history and outcome of biliary atresia is of considerable relevance to a European population. It is essential that there is further support for a pan-European registry with coordination of clinical standards, further participation of parent support groups, and implementation of online data entry and multidisciplinary clinical and basic research projects.

Abstract
Mutations in sarcoglycans have been reported to cause autosomal-recessive limb-girdle muscular dystrophies. In skeletal and cardiac muscle, sarcoglycans are assembled into a complex on the sarcolemma from four subunits (alpha, beta, gamma, delta). In this report, we present a detailed structural analysis of sarcoglycans using deletion study, limited proteolysis and co-immunoprecipitation. Our results indicate that the extracellular regions of sarcoglycans consist of distinctive functional domains connected by proteinase K-sensitive sites. The N-terminal half domains are required for sarcoglycan interaction. The C-terminal half domains of beta-, gamma- and delta-sarcoglycan consist of a cysteine-rich motif and a previously unrecognized conserved sequence, both of which are essential for plasma membrane localization. Using a heterologous expression system, we demonstrate that missense sarcoglycan mutations affect sarcoglycan complex assembly and/or localization to the cell surface. Our data suggest that the formation of a stable complex is necessary but not sufficient for plasma membrane targeting. Finally, we provide evidence that the beta/delta-sarcoglycan core can associate with the C-terminus of dystrophin. Our results therefore generate important information on the structure of the sarcoglycan complex and the molecular mechanisms underlying the effects of various sarcoglycan mutations in muscular dystrophies.

Abstract
UNLABELLED Mitochondrial respiratory chain disease may lead to neonatal or late onset liver failure, requiring liver transplantation. In rare cases, the disease is restricted to the liver and the patient is cured after surgery. More frequently, other organs are simultaneously involved and neuromuscular or other extra-hepatic symptoms may pre-exist, or appear in the post-transplant follow up. Pre-transplant evaluation should aim to rule out neurological disease, which may be difficult to differentiate from signs accompanying liver insufficiency. Cerebrospinal fluid lactic acid levels, compared to blood lactate, may be suggestive of central nervous system involvement. Of 11 cases with respiratory chain disorders who had liver transplantation in various centres, 4 are alive and well on follow up, and 6 died, three of them having developed neurological disease post orthotopic liver transplantation. All three patients with initial liver and gastro-intestinal disease died early after transplantation, indicating that these may be poor candidates for this procedure. CONCLUSION Liver transplantation is feasible in hepatic respiratory chain disorders, but extra-hepatic disease should be ruled out before transplantation. Extra-hepatic manifestations may, however, appear and cause patient death despite successful transplantation.

Abstract
According to data in the literature complications develop in association with colostomy in 20-66% of patients, occlusion of the colostomy occurs in 10-17%. The authors analyze their own group of 122 patients where in 1994-1998 a colostomy was made. Sixty-two patients were operated with developed ileus, 19 colostomies were later abolished and the passage per vias naturales was reconstructed. The authors recorded 38.5% complications, they were most frequent in axial transversostomies and sigmostomies, wound infections were most frequent. For prevention of complications the authors emphasize that stricter indications for colostomy should be used. The same applies to the selection of the type and site of colostomy and exact surgical technique, ATB prophylaxis and lavage, use of modern stomic appliances, perspectives of using the laparoscopic technique.

Abstract
OBJECTIVE The aim of this study was to evaluate previous teacher reports that children exposed to cocaine prenatally have more problem behaviors. METHODS A historical, prospective design was used. Maternal subjects (n = 116) of 6-year-old singleton, term (>/=36 weeks) children, and the children's first-grade teachers (n = 102) agreed to participate. The child's first-grade teacher, blinded to study design and exposure status, rated the child's behavior with the Conners' Teacher Rating Scales (CTRS) and an investigator-developed scale, the Problem Behavior Scale (PROBS 14), measuring behaviors reported by educators to be specific to cocaine exposure. Mothers were interviewed by telephone regarding demographic and socioeconomic factors. RESULTS Although the cocaine-exposed group had higher (more problem behaviors) for each of the CTRS subscales, the overall multivariate analysis of variance for the CTRS was not significant. Children exposed to cocaine prenatally had higher scores (more problem behaviors) for 11 of the 14 PROBS items and the overall multivariate analysis of variance relating prenatal cocaine exposure to the PROBS was significant (Wilkes' lambda =.775), even after controlling for gender and prenatal exposure to alcohol and cigarettes. CONCLUSIONS This pilot study supports that teachers blinded to exposure status of early elementary students did rate the cocaine-exposed group as demonstrating significantly more problem behaviors than control children. Although an important first step, postnatal factors that also may influence behavior were not evaluated; hence, causation is not addressed.

Abstract
Despite media reports and educators' concerns, little substantive data have been published to document or refute the emerging reports that children prenatally exposed to cocaine have serious behavioral problems in school. Recent pilot data from this institution have indeed demonstrated teacher-reported problem behaviors following prenatal cocaine exposure after controlling for the effects of prenatal alcohol use and cigarette exposure. Imperative in the study of prenatal exposure and child outcome is an acknowledgement of the influence of other control factors such as postnatal environment, secondary exposures, and parenting issues. We report preliminary evaluation from a large ongoing historical prospective study of prenatal cocaine exposure on school-age outcomes. The primary aim of this NIDA-funded study is to determine if a relationship exists between prenatal cocaine/alcohol exposures and school behavior and, if so, to determine if the relationship is characterized by a dose-response relationship. A secondary aim evaluates the relationship between prenatal cocaine/alcohol exposures and school achievement. Both relationships will be assessed in a black, urban sample of first grade students using multivariate statistical techniques for confounding as well as mediating and moderating prenatal and postnatal variables. A third aim is to evaluate the relationship between a general standardized classroom behavioral measure and a tool designed to tap the effects thought to be specific to prenatal cocaine exposure. This interdisciplinary research team can address these aims because of the existence of a unique, prospectively collected perinatal Database, funded in part by NIAAA and NICHD. The database includes repeated measures of cocaine, alcohol, and other substances for over 3,500 births since 1986. Information from this database is combined with information from the database of one of the largest public school systems in the nation. The final sample will be composed of over 600 first grade students for whom the independent variables, prenatal cocaine/alcohol exposures, were prospectively assessed and quantified at the university maternity center. After informed consent, the primary dependent variable, school behavior, is assessed, using the PROBS-14 (a teacher consensus developed instrument), the Child Behavior Check List, and the Conners' Teacher Rating Scale. The secondary dependent measure, school achievement, is measured by the Metropolitan Achievement Text and the Test of Early Reading Ability. Control variables, such as the environment and parenting, are measured by several instruments aimed at capturing the child and family ecology since birth. All analyses will be adjusted as appropriate for prospectively gathered control variables such as perinatal risk, neonatal risk, and other prenatal drug and cigarette exposures. Further adjustment will be made for postnatal social risk factors which may influence outcome. Of particular concern are characteristics of the home (adaptation of HOME), parent (depression, stress), and neighborhood (violence exposure). Finally, postnatal exposure to lead and other drugs is being considered.

Abstract
In times of cost reduction efforts the role of standard operating procedures for both medical and nursing procedures gets increasing importance. Such standards are necessary if the quality of patient care shall not suffer but even improve. While some sophisticated approaches are coming up with generation of clinical processes from formal protocol models in connection with documentation systems the clinical practice actually looks quite different: Paper-based "operating standards" are used in day-to-day work, if any. In this paper a simple and powerful WWW-based hypertext information system for easy provision and maintenance of nursing standards is presented.

Abstract
The authors present a group of 21 patients treated with the method of Lichtenstein with the use of polypropylene mesh Prolen. They used the method of an "inlay" mesh for recurrent groin and epigastric hernias, mostly by men. The men:women ratio was 19:2. They emphasise better healing, early recovery to work and almost no wound infection by use of this method.

Abstract
Abetalipoproteinemia (ABL) is an autosomal recessive disease characterized by the inability of the liver and intestine to secrete apolipoprotein B (apoB). Mutations in the microsomal triglyceride transfer protein (MTP) gene, but not the apoB gene, are responsible for the ABL phenotype. It is not clear how loss of MTP in ABL patients leads to a complete, but specific, block in the secretion of apoB. It is to this question that our work is directed. In cultured cells lacking MTP, translocation of apoB is completely arrested, leading to the hypothesis that apoB requires MTP in order to completely enter the lumen of the endoplasmic reticulum, the site of lipoprotein assembly. We examined this hypothesis by determining the presence in plasma of distinct N-terminal apoB peptides, produced exclusively from translocation arrested apoB, in the plasma of six ABL patients and six normal subjects. The data show that N-terminal apoB peptides are present in the plasma of six ABL patients, whereas intact apoB-100 was barely detectable. Moreover, the plasma of all six ABL patients displayed a 2000-fold increase in the amount of an 85 kDa N-terminal apoB peptide relative to apoB-100. These data provide the first in vivo data supporting the essential role that MTP plays in apoB translocation. In normal humans, varied expression of MTP may be responsible for the post-transcriptional regulation of apoB secretion.

Abstract
We have shown that preeclampsia is associated with insulin resistance. In the present study, we examined young normal, preeclamptic (PE), and gestational hypertensive (GH) nulliparous African-American women at term to investigate cellular determinants of this resistance and insulin and insulin-like growth factor-I (IGF-I) binding to partially purified erythrocyte receptors and receptor tyrosine kinase activity (TKA). Blood pressure was significantly elevated in PE and GH subjects as compared with controls. Insulin binding was similar in number and affinity in the three groups (femtomoles per microgram). IGF-I binding was increased in PE subjects as compared with either normals or GH subjects (0.2 +/- 0.02, 0.15 +/- 0.01, and 0.14 +/- 0.02 fmol/microgram protein). Insulin receptor TKA was increased in PE subjects as compared with normals when assessed either per microgram protein or per femtomole insulin binding (P < .01). In contrast, IGF-I-potentiated TKA was elevated in PE subjects only when assessed per microgram protein (P < .03). Thus, the increased number of IGF-I receptors in erythrocytes of PE subjects yields a net increase in receptor tyrosine kinase. Also, there is an augmentation of insulin receptor TKA in PE subjects. Together, these two alterations may be a compensatory mechanism for the insulin resistance associated with hypertensive diseases of pregnancy.

Abstract
Ataxia with isolated vitamin E deficiency (AVED) is an autosomal recessive neurodegenerative disease which maps to chromosome 8q13. AVED patients have an impaired ability to incorporate alpha-tocopherol into lipoproteins secreted by the liver, a function putatively attributable to the alpha-tocopherol transfer protein (alpha-TTP). Here we report the identification of three frame-shift mutations in the alpha TTP gene. A 744delA mutation accounts for 68% of the mutant alleles in the 17 families analysed and appears to have spread in North Africa and Italy. This mutation correlates with a severe phenotype but alters only the C-terminal tenth of the protein. Two other mutations were found in single families. The finding of alpha TTP gene mutations in AVED patients substantiates the therapeutic role of vitamin E as a protective agent against neurological damage in this disease.

Abstract
Problems associated with intravenous (IV) admixture preparation include contamination by microorganisms, human error and expense. To solve some of these problems, the Vialink system was developed by Travenol, Israel. This device enables enhanced sterility in clinical settings, since in the preparation of the admixture there is only a single penetration of the rubber seal of the vial. The dilution is performed immediately prior to administration, thereby reducing the possibility of wastage due to unused admixture. In addition, Vialink offers a means of double-checking the contents of the admixtures, since the emptied vial remains attached to the infusion bag. Results of our evaluation of this new system indicate that it offers substantial savings in preparation time and expense. It was suitable for 58.2% of all IV admixtures routinely hospital-prepared. The Vialink system may be a useful strategy, as it improves the quality of the service provided by the health service team and hospital pharmacists to their patients, and results in savings in budget and manpower.

Vitamin E supplementation reduces the incidence of diabetes but not insulitis in NOD mice. THE JOURNAL OF LABORATORY AND CLINICAL MEDICINE 1992; 119:503-7.

Abstract
The incidence of diabetes was reduced in non-obese diabetic (NOD) mice fed a diet containing 1000 IU/kg of vitamin E. Histologic examination of the islets of these mice, however, disclosed a frequency of insulitis that approximated the frequency found in animals fed conventional diets. The vitamin E-treated mice were not immunosuppressed, as judged by normal T cell subsets in the spleen and normal T cell proliferative responses to concanavalin A. NOD mice deprived of vitamin E were also protected from diabetes. However, these mice had delayed growth, reduced T cell numbers in the spleen, and impaired proliferative responses to mitogens, which is indicative of secondary immunodeficiency. The data are consistent with the view that antioxidant treatment may limit immunologically mediated damage to islet beta cells.

Abstract
The teratogenic effects of drinking during pregnancy on cognitive development were investigated in a cohort of disadvantaged mother-infant pairs. Three indices associated with maternal alcohol use were related to comprehensive cognitive measures obtained during five in-home assessments through age four years, ten months. Birth weight and a tally of craniofacial anomalies were also evaluated as early indicators of fetal alcohol damage. Multiple analyses relating the alcohol and cognitive measures provided no evidence of an adverse alcohol effect on cognitive development in the absence of Fetal Alcohol Syndrome. Assessments based on confidence intervals indicated that an average decrement of more than two points (IQ equivalent) on the five cognitive measures is unlikely for relatively heavy levels of maternal alcohol use or alcohol-related problems. Marginal relationships were observed between cognitive measures and the neonatal indicators, but depended heavily on the influence of a child exhibiting signs consistent with Fetal Alcohol Syndrome. This case therefore received special attention. The implications of the relationships involving the neonatal indicators were investigated using arguments based on path analysis.

Abstract
OBJECTIVE-To determine if a policy of early amniotomy resulted in a reduction in mean labour duration when compared to a policy of conservation of the membranes. DESIGN-A single-centre randomized controlled trial. SETTING-A tertiary care teaching hospital in Alberta, Canada. SUBJECTS-Ninety-seven term nulliparae in spontaneous labour, baby in cephalic presentation. INTERVENTION-Early amniotomy versus intent to keep membranes intact. MAIN OUTCOME MEASURES-Interval from randomization to delivery, rate of abnormalities of fetal heart rate tracings, cord artery blood pH, Apgar scores. RESULTS-The mean interval from randomization to delivery was 390.9 (SE 29.1) min in the amniotomy group and 442.9 (SE 34.1) min in the control group (P = 0.251). There were no differences between groups in the occurrence of fetal heart rate tracing abnormalities, nor was there a difference in the proportion of babies with abnormal Apgar scores, or abnormal cord pH (less than 7.20). CONCLUSION-The results of the study fail to support the long held belief that early amniotomy is an effective method for reducing labour duration.

Abstract
The effects of fetal alcohol exposure on language and speech acquisition were investigated in a cohort of socioeconomically disadvantaged urban children. Language development was assessed by instruments derived from the Expressive and Receptive Scales of the Sequenced Inventory of Communication Development (SICD) at 1, 2, and 3 years, and by indices constructed from a taped speech sample at age 2 years. Three indices of maternal drinking were supplemented with birth weight and a tally of craniofacial anomalies as early indicators of fetal alcohol damage. No statistically significant relationships were found between the alcohol and language indices after statistical control for confounding variables. The anomalies tally was marginally related to reduced language scores. The statistical significance of this relationship, depended, however, on a single child with the characteristics of fetal alcohol syndrome. The pattern of results suggested that the anomalies tally, and to a lesser extent birth weight, are more sensitive indicators of fetal alcohol exposure than subsequent language development.

Abstract
The Millon Clinical Multiaxial Inventory (MCMI) is a promising, yet somewhat unproven psychometric inventory developed to identify clinical syndromes and personality traits consonant with the Diagnostic and Statistical Manual of Mental Disorders (3rd ed. [DSM-III]; American Psychiatric Association, 1980). The stability of its measures for both the theoretically more stable personality characteristics and the clinical syndromes was investigated in a group of depressed psychiatric outpatients. In this test-retest design with a 3-month interval between tests, clinical syndrome scales of relevance changed significantly as expected. However, many of the personality scales also changed significantly. Only four of the personality scales met a two-fold test of stability. Findings are discussed in terms of characteristics of self-report inventories such as the MCMI, the uniqueness of the depressed population, and characteristics of personality disorders.

Abstract
Personality disorders frequently are seen among depressed psychiatric inpatients. In a group of 73 depressed psychiatric outpatients, this study identified 85% whose response to the Millon Clinical Multiaxial Inventory (MCMI) suggested a personality disorder. On retest 12 weeks later, only 64% manifested a response style consistent with the DSM-III personality disorders. These findings are discussed in relation to methodology, characteristics of the MCMI, and the response style of the depressed patient, which may lead to an overidentification of personality disorders on a self-report measure. Related aspects of the diagnostic criteria for personality disorders also are discussed.

Abstract
The effects of intravenous (IV) ritodrine therapy on capillary endothelial damage and colloid osmotic pressure were examined in 15 patients in premature labor. Plasma fibronectin, a marker for capillary endothelial damage, did not change significantly after IV ritodrine therapy. Plasma colloid osmotic pressure was lowered following ritodrine therapy (P less than 0.05). Pretreatment plasma fibronectin levels in the study and control groups were similar. Interestingly, pretreatment colloid osmotic pressure in the study group was significantly lower than that of the control group (P less than 0.05). Our data suggest that there is no evidence of capillary endothelial damage following ritodrine therapy. Lower levels of plasma colloid osmotic pressure in patients with preterm labor, which are further reduced with IV ritodrine therapy, may predispose these patients to pulmonary edema.

Abstract
A 30-year-old woman was thought to have Friedreich's disease because of progressive ataxia, dysarthria, and titubation from age 3 years. Her diet was normal, and there were neither symptoms nor laboratory evidence of liver disease or fat malabsorption. Serum vitamin E content and the ratio of serum vitamin E to total serum lipid were very low, but serum vitamin A, cholylglycine, and lipid levels were normal, as was an oral vitamin E tolerance test. Muscle biopsy showed the lysosomal inclusions of vitamin E deficiency. Mitochondria had normal oxidative phosphorylation using polarographic assays. The cause of her vitamin E deficiency was unknown.

Abstract
Two cases of selenium ingestion in children are described; one child with severe cystic fibrosis died. Both children had cystic fibrosis and both had low serum chloride in association with selenium usage. Neither child was exposed to excessive heat or cold weather, factors known to salt-deplete children were cystic fibrosis, although one child was dehydrated during a summer month on initial presentation. One child had protein-calorie malnutrition, a condition known to enhance selenium toxicity in animals. We conclude that selenium is a potential hazard in its use as a health food fad for children with cystic fibrosis and in overdose ingestions. Thus selenium supplementation may have contributed to the morbidity and mortality reported here.
