Background
The implantation of a leadless right ventricular pacemaker (LPM) may be complicated by tricuspid valve injury or interference with tricuspid valve function.
Purpose
Characterize the nature, causes, and outcomes of tricuspid valve injury and functional interference due to LPM implantation.
Methods
The Food and Drug Administration’s Manufacturers and User Facility Device Experience (MAUDE) database was queried for tricuspid valve adverse events involving the Medtronic Micra LPM that were reported by the manufacturer.
Results
From 2016-October 2021, 19 patients suffered a tricuspid valve adverse event, including damage to the leaflets, papillary muscle, or chordae tendineae (n=14; 74%); interference with valve closure (n=3; 16%); and 2 LPMs were irretrievably wedged in the tricuspid valve apparatus. Damaged valves included: 1) torn leaflet or chordal tissue found in the delivery system (n=6) after complicated or failed LPM recapture that necessitated removal without the LPM retracted into the delivery system; all patients developed tricuspid regurgitation, and one patient died. 2) valve damage by the delivery system either directly (n=6) or during LPM recapture (n=1) or removal by a snare (n=1); all patients had new or worsening tricuspid regurgitation; one patient died, 2 had valve repair, and one valve was replaced. In three patients the LPM interfered with valve closure; one patient had valve replacement, one underwent LPM removal, and one was treated medically. Of the 2 LPMs wedged in the tricuspid valve apparatus, one required surgical removal and one was abandoned.
Conclusion
Tricuspid valve trauma during LPM implantation may cause significant regurgitation that results in poor outcomes and requires medical or surgical intervention. Mechanisms include direct valve injury by the delivery system, complications of difficult or unsuccessful LPM recapture, and LPM interference with valve function.

Abstract
Autism spectrum disorder (ASD) is the commonest neurodevelopmental disability. It is a highly complex disorder with an increasing prevalence and an unclear etiology. Consensus indicates that ASD arises as a genetically modulated, and environmentally influenced condition. Although pathogenic rare genetic variants are detected in around 20% of cases of ASD, no single factor is responsible for the vast majority of ASD cases or that explains their characteristic clinical heterogeneity. However, a growing body of evidence suggests that ASD susceptibility involves an interplay between genetic factors and environmental exposures. One such environmental exposure which has received significant attention in this regard is maternal immune activation (MIA) resulting from bacterial or viral infection during pregnancy. Reproducible rodent models of ASD are well-established whereby induction of MIA in pregnant dams, leads to offspring displaying neuroanatomical, functional, and behavioral changes analogous to those seen in ASD. Blockade of specific inflammatory cytokines such as interleukin-17A during gestation remediates many of these observed behavioral effects, suggesting a causative or contributory role. Here, we review the growing body of animal and human-based evidence indicating that interleukin-17A may mediate the observed effects of MIA on neurodevelopmental outcomes in the offspring. This is particularly important given the current corona virus disease-2019 (COVID-19) pandemic as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during pregnancy is a potent stimulator of the maternal immune response, however the long-term effects of maternal SARS-CoV-2 infection on neurodevelopmental outcomes is unclear. This underscores the importance of monitoring neurodevelopmental outcomes in children exposed to SARS-CoV-2-induced MIA during gestation.

Abstract
Autism Spectrum disorder is one of the commonest and most important neurodevelopmental conditions affecting children today. With an increasing prevalence and an unclear aetiology, it is imperative we find early markers of autism, which may facilitate early identification and intervention. Alterations of gestational cytokine profiles have been reported in mothers of autistic children. Increasing evidence suggests that the intrauterine environment is an important determinant of autism risk. This study aims to examine the mid-gestational serum cytokine profiles of the mothers of autistic children from a well-characterised birth cohort. A nested sub-cohort within a large mother-child birth cohort were identified based on a confirmed multi-disciplinary diagnosis of autism before the age 10 years and neuro-typical matched controls in a 2:1 ratio. IFN-γ, IL-1β, IL-4, IL-6, IL-8, IL-17A, GMCSF and TNFα were measured in archived maternal 20-week serum using MesoScale Diagnostics multiplex technology and validation of our IL-17A measurements was performed using an ultrasensitive assay. From a cohort of 2137 children, 25 had confirmed autism before 10 years and stored maternal serum from mid-gestation. We examined the sera of these 25 cases and 50 matched controls. The sex ratio was 4:1 males to females in each group, and the mean age at diagnosis was 5.09 years (SD 2.13). We found that concentrations of IL-4 were significantly altered between groups. The other analytes did not differ significantly using either multiplex or ultra-sensitive assays. In our well-characterised prospective cohort of autistic children, we confirmed mid-gestational alterations in maternal IL-4 concentrations in autism affected pregnancies versus matched controls. These findings add to promising evidence from animal models and retrospective screening programmes and adds to the knowledge in this field.

Abstract
The oxytocin (OXT) system has been strongly implicated in the regulation of social behaviour and anxiety, potentially contributing to the aetiology of a wide range of neuropathologies. Birth by Caesarean-section (C-section) results in alterations in microbiota diversity in early-life, alterations in brain development and has recently been associated with long-term social and anxiety-like behaviour deficits. In this study, we assessed whether OXT intervention in the early postnatal period could reverse C-section-mediated effects on behaviour, and physiology in early life and adulthood. Following C-section or per vaginum birth, pups were administered with OXT (0.2 or 2 μg/20 μl; s.c.) or saline daily from postnatal days 1-5. We demonstrate that early postnatal OXT treatment has long-lasting effects reversing many of the effects of C-section on mouse behaviour and physiology. In early-life, high-dose OXT administration attenuated C-section-mediated maternal attachment impairments. In adulthood, low-dose OXT restored social memory deficits, some aspects of anxiety-like behaviour, and improved gastrointestinal transit. Furthermore, as a consequence of OXT intervention in early life, OXT plasma levels were increased in adulthood, and dysregulation of the immune response in C-section animals was attenuated by both doses of OXT treatment. These findings indicate that there is an early developmental window sensitive to manipulations of the OXT system that can prevent lifelong behavioural and physiological impairments associated with mode of birth.

Abstract
OBJECTIVE To evaluate umbilical cord messenger RNA (mRNA) expression as biomarkers for the grade of hypoxic-ischemic encephalopathy (HIE) and long-term neurodevelopment outcome. STUDY DESIGN Infants were recruited from the BiHiVE1 study, Ireland (2009-2011), and the BiHiVE2 study, Ireland, and Sweden (2013-2015). Infants with HIE were assigned modified Sarnat scores at 24 hours and followed at 18-36 months. mRNA expression from cord blood was measured using quantitative real-time polymerase chain reaction. RESULTS We studied 124 infants (controls, n = 37; perinatal asphyxia, n = 43; and HIE, n = 44). Fzd4 mRNA increased in severe HIE (median relative quantification, 2.98; IQR, 2.23-3.68) vs mild HIE (0.88; IQR, 0.46-1.37; P = .004), and in severe HIE vs moderate HIE (1.06; IQR, 0.81-1.20; P = .003). Fzd4 mRNA also increased in infants eligible for therapeutic hypothermia (1.20; IQR, 0.92-2.37) vs those who were ineligible for therapeutic hypothermia group (0.81; IQR, 0.46-1.53; P = .017). Neurodevelopmental outcome was analyzed for 56 infants. Nfat5 mRNA increased in infants with severely abnormal (1.26; IQR, 1.17-1.39) vs normal outcomes (0.97; IQR, 0.83-1.24; P = .036), and also in infants with severely abnormal vs mildly abnormal outcomes (0.96; IQR, 0.80-1.06; P = .013). Fzd4 mRNA increased in infants with severely abnormal (2.51; IQR, 1.60-3.56) vs normal outcomes (0.74; IQR, 0.48-1.49; P = .004) and in infants with severely abnormal vs mildly abnormal outcomes (0.97; IQR, 0.75-1.34; P = .026). CONCLUSIONS Increased Fzd4 mRNA expression was observed in cord blood of infants with severe HIE; Nfat5 mRNA and Fzd4 mRNA expression were increased in infants with severely abnormal long-term outcomes. These mRNA may augment current measures as early objective markers of HIE severity at delivery.

Abstract
Hypoxic ischemic encephalopathy (HIE) is the most frequent cause of acquired infant brain injury. Early, clinically relevant biomarkers are required to allow timely application of therapeutic interventions. We previously reported early alterations in several microRNAs (miRNA) in umbilical cord blood at birth in infants with HIE. However, the exact timing of these alterations is unknown. Here, we report serial changes in six circulating, cross-species/bridging biomarkers in a clinically relevant porcine model of neonatal HIE with functional analysis. Six miRNAs—miR-374a, miR-181b, miR-181a, miR-151a, miR-148a and miR-128—were significantly and rapidly upregulated 1-h post-HI. Changes in miR-374a, miR-181b and miR-181a appeared specific to moderate-severe HI. Histopathological injury and five miRNAs displayed positive correlations and were predictive of MRS Lac/Cr ratios. Bioinformatic analysis identified that components of the bone morphogenic protein (BMP) family may be targets of miR-181a. Inhibition of miR-181a increased neurite length in both SH-SY5Y cells at 1 DIV (days in vitro) and in primary cultures of rat neuronal midbrain at 3 DIV. In agreement, inhibition of miR-181a increased expression of BMPR2 in differentiating SH-SY5Y cells. These miRNAs may therefore act as early biomarkers of HIE, thereby allowing for rapid diagnosis and timely therapeutic intervention and may regulate expression of signalling pathways vital to neuronal survival.

Abstract

The study is partially funded by Medtronic and the Minneapolis Heart Institute Foundation.
Background/Introduction: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is characterized by replacement of the myocardium with fibrous and fatty tissue that may lead to an increased risk of ventricular arrhythmias and heart failure. Although left ventricular (LV) and biventricular forms have been identified post-mortem resulting in the increased use of the term arrhythmogenic cardiomyopathy, there is only inclusion of right ventricular wall motion abnormalities in the taskforce diagnostic criteria.
Purpose
The aim of our study was to examine the utility of cardiac magnetic resonance (CMR) imaging in characterizing LV or biventricular involvement with late gadolinium enhancement (LGE) in a large cohort of patients with suspected ARVC.
Methods
Retrospective, single-institution, chart review of 76 patients diagnosed with ARVC between January 2009 and July 2019. Data collection and analysis included baseline demographics and parameters specific to diagnosis (definite, borderline, or possible) and risk stratification of ARVC based on 2019 modified taskforce criteria, as well as detailed CMR evaluation.

Of the 76 patients with ARVC, 66 (87%) had at least one CMR with gadolinium administered. In that subset of patients, 27 (41%) had LGE. Of those with LGE, LV involvement was identified in 23 (85%) patients. The pattern of LGE was not localized to one myocardial region but demonstrated variable LV enhancement patterns including anterior, inferior, lateral, septal, basal, mid, apical, and from the sub-epicardium into the mid-myocardium.
Conclusions
Left ventricular involvement reflected by LGE was identified in a high percentage of patients with suspected ARVC, and there was significant variation in the pattern of distribution in terms of region and depth of myocardial involvement. While post-mortem examination of patients with ARVC demonstrates a high prevalence of left ventricular involvement, this study shows that CMR can consistently detect late gadolinium enhancement, and ARVC should be considered in the differential diagnosis for biventricular cardiomyopathy. The identification of variable locations of LGE within the LV suggests there is more than one phenotype, and this imaging modality may help to clarify the implications of left ventricular involvement in disease progression.

Abstract
MicroRNAs are a class of small non-coding RNA that regulate gene expression at a post-transcriptional level. MicroRNAs have been identified in various body fluids under normal conditions and their stability as well as their dysregulation in disease has led to ongoing interest in their diagnostic and prognostic potential. Circulating microRNAs may be valuable predictors of early-life complications such as birth asphyxia or neonatal seizures but there are relatively few data on microRNA content in plasma from healthy babies. Here we performed small RNA-sequencing analysis of plasma processed from umbilical cord blood in a set of healthy newborns. MicroRNA levels in umbilical cord plasma of four male and four female healthy babies, from two different centres were profiled. A total of 1,004 individual microRNAs were identified, which ranged from 426 to 659 per sample, of which 269 microRNAs were common to all eight samples. Many of these microRNAs are highly expressed and consistent with previous studies using other high throughput platforms. While overall microRNA expression did not differ between male and female cord blood plasma, we did detect differentially edited microRNAs in female plasma compared to male. Of note, and consistent with other studies of this type, adenylation and uridylation were the two most prominent forms of editing. Six microRNAs, miR-128-3p, miR-29a-3p, miR-9-5p, miR-218-5p, 204-5p and miR-132-3p were consistently both uridylated and adenylated in female cord blood plasma. These results provide a benchmark for microRNA profiling and biomarker discovery using umbilical cord plasma and can be used as comparative data for future biomarker profiles from complicated births or those with early-life developmental disorders.

Abstract
In a previous paper one of us (4) has elaborated a theory relating drug action to personality. According to this theory, depressant drugs increase cortical inhibition (Pavlov) or reactive inhibition (Hull), thus producing an extraverting effect on personality, while stimulant drugs decrease inhibition and produce an introverting effect in behaviour. It was also suggested in this paper that a direct proof of the hypothesis might be obtained by making predictions regard ing the effects of stimulant and depressant drugs on a variety of experimental laboratory situations connected with the general theory of inhibition and excitation.

Abstract
The number of people forced to flee their homes and move around the world is increasing rapidly. Such refugee populations are not only more likely to have poor physical, mental and social health outcomes but also to experience difficulties accessing health services in their new country. In particular, children from refugee backgrounds are at increased risk of poor oral health which in time is associated with poor adult oral health and impacts on child health (e.g. growth and development) and well-being. To date, there is little evidence about the nature and extent of their oral health problems nor interventions to improve their oral health status. This article summarises the evidence surrounding the oral health status of children from refugee backgrounds. In addition, a systematic review of the international literature over the past 10 years is presented which identifies interventions to improve the oral health of these vulnerable paediatric populations. Based on this evidence, potential strategies available to dental service providers to optimise provision of responsive dental care are discussed.

Abstract
The purpose of this study was to test the efficacy of a tri-modal intervention (LEVITY) to improve women's mood. This eight-week randomized experiment with a placebo-control group targeted women with symptoms of mild to moderate depression. Women in the intervention group were instructed to take a brisk 20-minute outdoor walk at target heart rate of 60% of maximum heart rate, to increase light exposure throughout the day and to take a specific vitamin regimen. Women in the control group took a daily placebo vitamin. The sample consisted of 112 women ages 19-78 who reported mild to moderate depressive symptoms. They were in otherwise good health and were not currently taking any mood-altering medication. Pre- and post-intervention assessment utilized live measures of mood: Center for Epidemiology Studies Depression Scale, Profile of Mood States, Depression-Happiness Scale, Rosenberg Self-Esteem Scale, and the General Well-Being Schedule. Analysis of covariance indicated that the intervention was effective in improving women's overall mood, self-esteem, and general sense of well-being and in decreasing symptoms on two measures of depression. Of particular note, the data from all five outcome measures supported the efficacy of the intervention. In addition, a high level of adherence to the intervention protocol was observed with two-thirds of the women reporting 100% adherence. Study implications suggest that this type of intervention may provide an effective, clinically manageable therapy for mild-to-moderately depressed women who prefer a self-directed approach or who have difficulties with the cost or side-effects of medication or psychotherapy.

Abstract
This study of personnel in local health departments (LHDs) focused on two predominantly rural states: Idaho and Wyoming. Although in the same region of the country, the structure of local public health is different in each state. Idaho's regionalized LHDs are relatively autonomous, whereas Wyoming's are county based, with many public health functions retained at the state level. The majority of professionals are nurses followed by environmental health workers and sanitarians, similar to data reported nationally. With increased emphasis on core public health functions of policy, assurance, and assessment, rural LHDs will be challenged to redirect the functions of their workforce.

Abstract
Abundant data is present to implicate oxidatively modified low-density lipoprotein (oxLDL) in enhanced atherogenesis. Among the factors involved in LDL oxidation, an important role has been attributed to human 15-lipoxygenase (LO) and its murine analog 12-LO. The expression of these peroxidizing enzymes is under the control of cytokines, the principal of which is IL-4. In the present study we tested the hypothesis that knocking out the IL-4 gene from C57BL/6 mice would result in suppression of fatty streaks. For this purpose, we have fed 45 female IL-4 transgenic knockout (IL-4T KO) and 45 wild-type (WT) mice an atherogenic diet for 15 weeks. Consecutive determinations of the lipid profile from both study groups were performed at monthly intervals, and fatty streak formation was assessed at the aortic sinus level, upon sacrifice. The two study groups did not differ significantly with respect to the lipid profile or the uptake and degradation of iodinated oxLDL by their peritoneal macrophages. We found that the endogenous deficiency of IL-4 did not confer protection from early atherosclerosis in the IL-4T KO as compared to their WT littermates (determined at the aortic sinus). Immunohistochemical studies, Western blots and 12/15-LO activity assays revealed the presence and activity of 12/15-LO in macrophages of WT mice as well as in IL-4T KO mice. Both did not differ significantly between the study groups. The data from this study imply that deficiency in IL-4 does not affect early atherosclerosis in C57BL/6 mice fed a high-cholesterol diet.

Abstract
Parental fears concerning seizure occurrence may be associated with behavioral changes within the home environment. One possible change involves sleeping arrangements. Questionnaires concerning demographics, medical history, and sleeping arrangements were completed by parents of 179 children with epilepsy and by parents of 155 children with diabetes for comparison purposes. Based on parental response, 40 (22%) children with epilepsy changed to less independent sleeping arrangements. Logistic regression suggested that parental concern over seizure occurrence was highly associated with this change (p=<0.001). In contrast, 13 (8%) of the children with diabetes changed to a less independent sleep pattern. Results suggest changes in sleeping arrangements may alert the pediatrician to possible parental anxiety that may need to be addressed.

Abstract
BACKGROUND In most states, the Pregnancy Risk Assessment Monitoring System (PRAMS) is the only source for state-specific, population-based data on the prevalence of unintended pregnancy among women having a live birth. These data can be used in a variety of ways to inform state policies and programs aimed at the prevention of unintended pregnancy. OBJECTIVES This paper highlights the programmatic and policy development activities undertaken by three states in relation to unintended pregnancy as well as the role that PRAMS data played in those efforts. RESULTS Georgia, Oklahoma, and Washington have used PRAMS data to gain support for program initiatives directed at unintended pregnancy, to promote policies aimed at either monitoring or reducing unintended pregnancy, and to acquire additional funds for related programs, such as family planning.

Abstract
Despite numerous studies, the precise role of dietary n-6 polyunsaturated fatty acids in the pathogenesis of atherosclerosis remains controversial. It has been shown that feeding an n-6-enriched diet resulted in decreased atherosclerosis in African green monkeys and was associated with a reduction in LDL levels. However, other authors reported that n-6 supplementation increased the oxidative stress and the susceptibility of LDL to undergo in vitro oxidation, thus potentially enhancing atherosclerosis. The present study was designed to investigate the effect of dietary supplementation of n-6 polyunsaturated fats (safflower oil), as compared with a saturated fat-rich diet (Paigen), on the blood lipid profile and atherosclerosis in two mouse models. In the first experiment, female C57BL/6 mice (n=23-30 per group) were fed a cholate containing Paigen diet, a safflower oil-rich diet (with cholate), or normal chow for 15 weeks. No significant differences between the high fat diet groups were evident with respect to total cholesterol, LDL, HDL or triglyceride levels. The extent of aortic sinus fatty streaks did not differ significantly between the two groups. In the second experiment, LDL-receptor-deficient (LDL-RD) mice (n=20-30 per group) were randomized into similar dietary regimens. Mice consuming a safflower oil-enriched diet developed significantly less atherosclerosis, in comparison with Paigen diet-fed mice. A reduction in LDL levels, although not of a similar magnitude as the reduction in atherosclerosis, was evident in the safflower oil-fed mice when compared to the Paigen diet-fed littermates. In both mouse models of atherosclerosis, LDL isolated from the plasma of mice on the n-6 polyunsaturated diet was rendered slightly more susceptible to oxidation in vitro, as indicated by a shorter lag period for diene formation. Thus, the effects of n-6 fatty acids on the lipoprotein composition and other potential influences may have contributed to the anti-atherogenic effect in the LDL-RD mouse model.

Abstract
OBJECTIVE To analyze the long-term nutritional effects of supplemental gastrostomy feedings in undernourished patients with cystic fibrosis. DESIGN Longitudinal, retrospective assessment of anthropometric measures before and for up to 4 years after gastrostomy. SUBJECTS/SETTING All patients at a large cystic fibrosis care center who underwent gastrostomy between 1980 and 1993 when they were at least 1 year old and were followed up for a minimum of 1 year after gastrostomy. STATISTICAL ANALYSES PERFORMED The Mann-Whitney U test was used to compare anthropometric values measured during 4 postgastrostomy time intervals with values measured during the year preceding gastrostomy. RESULTS The 21 patients ranged in age from 1.1 to 20.8 years (median age = 7.4 years). They had mild to moderate malnutrition at the time of gastrostomy. Patients were followed up for a mean of 39 months after gastrostomy. Supplemental feedings were associated with significant improvements in weight and height percentiles for age, and in weight as a percentage of ideal weight. Improvement in weight occurred earlier than improvement in height. Among subjects followed up for at least 18 months after gastrostomy, median weight percentile for age increased from 2% for the year before gastrostomy to 12% for the period 6 to 18 months after gastrostomy (P < .001) and 19% for the period 30 to 48 months after gastrostomy (P = .002 compared with before gastrostomy). Other nutritional parameters followed similar, although less dramatic patterns. Gastrostomy feedings were well tolerated and associated with only minor complications. CONCLUSIONS Long-term gastrostomy feedings appear to be a safe and effective means of improving nutrition in malnourished patients with cystic fibrosis. Clinical dietitians should function as care managers for patients with cystic fibrosis who are receiving supplemental gastrostomy feedings.

Abstract
The harbor seal (Phoca vitulina) has one of the broadest geographic distributions of any pinniped, stretching from the east Baltic, west across the Atlantic and Pacific Oceans to southern Japan. Although individuals may travel several hundred kilometers on annual feeding migrations, harbor seals are generally believed to be philopatric, returning to the same areas each year to breed. Consequently, seals from different areas are likely to be genetically differentiated, with levels of genetic divergence increasing with distance. Differentiation may also be caused by long-standing topographic barriers such as the polar sea ice. We analyzed samples of 227 harbor seals from 24 localities and defined 34 genotypes based on 435 bp of control region sequence. Phylogenetic analysis and analysis of molecular variance showed that populations in the Atlantic and Pacific Oceans and east and west coast populations of these oceans are significantly differentiated. Within these four regions, populations that are geographically farthest apart generally are the most differentiated and often do not share genotypes or differ in genotype frequency. The average corrected sequence divergence between populations in the Atlantic and Pacific Oceans is 3.28% +/- 0.38% and those among populations within each of these oceans are 0.75% +/- 0.69% and 1.19% +/- 0.65%, respectively. Our results suggest that harbor seals are regionally philopatric, on the scale of several hundred kilometers. However, genetic discontinuities may exist, even between neighboring populations such as those on the Scottish and east English coasts or the east and west Baltic. The mitochondrial data are consistent with an ancient isolation of populations in both oceans, due to the development of polar sea ice. In the Atlantic and Pacific, populations appear to have been colonized from west to east with the European populations showing the most recent common ancestry. We suggest the recent ancestry of European seal populations may reflect recolonization from Ice Age refugia after the last glaciation.

Abstract
PURPOSE To determine the usefulness of CT angiography in the setting of suspected acute subarachnoid hemorrhage or intracranial aneurysm. METHODS We prospectively studied 68 patients suspected of having subarachnoid hemorrhage or an intracranial aneurysm with noncontrast CT of the head followed immediately by contrast-enhanced helical CT of the circle of Willis with three-dimensional reconstruction. Twenty-seven patients with CT findings positive for subarachnoid hemorrhage or intracranial aneurysm were evaluated with digital subtraction angiography or MR angiography within 12 hours of CT angiography. Patients with negative CT/CT angiography findings were followed up with lumbar puncture. RESULTS CT angiography showed 23 of 24 aneurysms and 2 of 2 arteriovenous malformations (sensitivity, 96%; specificity, 100%). Aneurysm size ranged from 2 to 40 mm (mean, 7.9 mm). Interobserver variability was 10%. In the 23 cases of subarachnoid hemorrhage, cisternal blood did not limit the three-dimensional reconstruction. Two patients with aneurysms on CT angiography had normal noncontrast scans. CONCLUSIONS CT angiography of the circle of Willis is a useful technique for evaluation of suspected acute subarachnoid hemorrhage and intracranial aneurysm. It provides anatomic display of intracranial aneurysms, allowing for planning of conventional angiography and surgical approach. In selected cases, CT angiography may eliminate the need for preoperative conventional angiography.

Abstract
PURPOSE To evaluate in a randomized clinical trial systemic chemoendocrine therapy used as primary (neo-adjuvant) treatment before surgery in women with primary operable breast cancer. PATIENTS AND METHODS Patients aged less than 70 years with clinically palpable, primary operable breast cancer diagnostically confirmed by fine-needle aspiration cytology (FNAC) and suitable for treatment with surgery, radiotherapy, cytotoxic chemotherapy, and tamoxifen were considered eligible. Patients randomized to neoadjuvant treatment received four cycles of chemo-therapy for 3 months before surgery followed by another four cycles after surgery, and were compared with patients randomized to adjuvant therapy who received eight cycles of chemotherapy over 6 months after surgery. RESULTS Of 212 patients who were randomized to receive either adjuvant (n = 107) or neoadjuvant (n = 105) chemoendocrine therapy, 200 are now assessable for response. The two groups are comparable for age, menopausal status, disease stage, and surgical requirements. The overall clinical response rate was 85%, with a complete histologic response rate of 10%. There was a significant reduction in the requirement for mastectomy in patients who received neoadjuvant treatment (13%) as compared with those who received adjuvant therapy (28%) (P < .005). Symptomatic and hematologic acute toxicity was low and similar for adjuvant and neoadjuvant therapy. The median follow-up period for patients in this trial is 28 months, during which time four patients have relapsed locally and 20, including one of the local relapses, have developed metastatic disease, 19 of whom have died. The follow-up period is too brief to evaluate relapse rate or survival duration. CONCLUSION This trial confirms previous reports of a high rate of response to neoadjuvant therapy, but is the first to include small primary cancers and to show, in the context of a randomized trial, a reduction in the requirement for mastectomy. Until disease-free and overall survival data are available from the larger National Surgical Adjuvant Breast and Bowel Project (NSABP)-18 trial, such neoadjuvant treatment cannot be recommended outside of a clinical trial.

Abstract
The effects of functional communication training, extinction, and response chaining on 3 subjects' escape-maintained aberrant behavior were evaluated using a multielement design. Functional communication training consisted of teaching subjects a verbal response that was functionally equivalent to their aberrant behavior. Subjects initially were allowed to escape from a task contingent on the trained verbal response. In subsequent treatment phases, escape was contingent on the trained verbal response plus the completion of the specified number of steps in the task (response chaining). The number of steps was increased until a subject completed the task to obtain a break. Results showed that the treatment reduced rates of aberrant behavior and that the chaining procedure was effective in decreasing the availability of escape.

Abstract
Dietary supplementation with fish oils high in the omega-3 fatty acids, eicosapentaenoic acid and docosahexaenoic acid, may have an antiinflammatory effect. We determined whether patients with cystic fibrosis (CF) could incorporate omega-3 fatty acids into their plasma and cell membrane phospholipids without adverse effects. In this double-blind study, 12 patients with pancreatic insufficiency who have CF (mean age, 12.2 +/- 5.4 (SD) years) and 13 subjects without CF (mean age, 13.4 +/- 6.3 (SD) years) were randomly assigned to ingest 8 gm daily of either encapsulated fish oil (3.2 gm of eicosapentaenoic acid and 2.2 gm of docosahexaenoic acid daily) or olive oil ethyl esters for 6 weeks. Two of seven and two of five patients with CF who received fish and olive oils, respectively, and one of eight and none of five subjects without CF discontinued taking the capsules before 6 weeks because of eructation or diarrhea. Significant incorporation of omega-3 fatty acids into plasma and erythrocyte membrane phospholipids was observed in subjects with and those without CF randomly assigned to the fish oil treatment. For example, in subjects randomly assigned to receive fish oil, the eicosapentaenoic acid/arachidonic acid ratio in plasma increased 9.8-fold, from 0.04 +/- 0.02 (mean +/- SEM) to 0.39 +/- 0.11 (p = 0.02), in the patients with CF (n = 7) and 23.0-fold, from 0.04 +/- 0.01 to 0.92 +/- 0.17 (p = 0.001), in the subjects without CF (n = 8) who received fish oil (p = 0.02, patients with CF vs subjects without CF at 6 weeks). No clinically or statistically significant changes from baseline were observed in platelet aggregation or levels of vitamin E or A in subjects who received fish oil. Future studies are indicated to determine whether omega-3 fatty acid enrichment provides a clinically beneficial antiinflammatory effect in patients with CF.

Abstract
The 1987 to 1991 direct medical costs and service utilization of Class IV Human Immunodeficiency Virus (HIV) patients cared for at a Group Health Cooperative of Puget Sound (GHC) are described and compared across four time periods: 1987-'88, 1989, 1990, and 1991. Cost and utilization information for an age- and sex-matched control group of GHC enrollees not having Class IV HIV conditions are also compared to those of the Class IV HIV group. Data are presented on pharmacy, inpatient care, outpatient visits by physician specialty, laboratory, radiology, home health/hospice and other costs. The costs of the Class IV HIV population are, on average, 20 times those of the control group. The percent distribution of the control group's costs did not experience much change from 1989 to 1991. Conversely, the Class IV HIV group experienced a shift in costs from the inpatient to outpatient setting from 1987-'88 to 1989. This shift was temporary, as the locus of care shifted back to the inpatient setting over the following 2 years. Anecdotal evidence suggests that antiretroviral treatment may have led to a period in which patients required less intensive settings to manage their illness. Inpatient costs may have increased as the initial benefit of zidovudine treatment began to wane. The Class IV HIV population had greater percent of total expenses in pharmacy, laboratory, radiology, and home health/hospice services, and lower percent of total expenses in outpatient primary and specialty care than the control group.

Abstract
An infant who died of complications of osteogenesis imperfecta (OI) at 22 days of age had a 46,XY,inv(7)(p13q22) karyotype. His mother carried the same inversion. One breakpoint of the inversion was within the region of the gene for alpha 2(I) procollagen. The product of this gene is a component of type I collagen, the principal collagen synthesised by osteoblasts. Karyotypic abnormalities involving type I collagen gene sites have not previously been reported in association with OI.

Abstract
A modified latex agglutination (LA) test was compared with Gram-staining and counterimmunoelectrophoresis (CIE) for the rapid detection in the cerebrospinal fluid (CSF) of antigen to Haemophilus influenzae type b, Neisseria meningitidis groups A, B and C, Escherichia coli K1, Streptococcus pneumoniae and group B streptococci, seven frequent causes of bacterial meningitis in children. Of 50 CSF samples from patients with culture-proven bacterial meningitis 90% were correctly shown by the LA test to contain antigen of the responsible organism. Gram-staining revealed organisms in 80% of 45 of these samples. In 75% of the 40 samples that were of sufficient volume for CIE, positive results for the appropriate antigen were obtained. The concentration of antigen detected in the CSF by the LA test varied from undetectable to 800 000 ng/ml. Patients with a high concentration (more than 2000 ng/ml or a positive result at dilutions of CSF over 1/8) were significantly more likely to have a poor response to therapy (two died and two had persistent pleocytosis or bacteria in the CSF) than patients with a lower concentration (4/16 v. 0/18, P < 0.05). After appropriate therapy was begun the concentration of antigen fell dramatically, but measurable amounts of antigen persisted in the CSF for up to 6 days. The LA test detected bacterial antigen at concentrations 2 to 70 times below the lower limit detected by CIE. In seven additional patients who had received antibiotics before lumbar puncture was performed the LA test detected antigen from meningitis-causing bacteria even though cultures of the CSF were sterile. In another 145 patients who did not have meningitis the results of the LA test were negative. The LA test, done as described in this article, is easier to perform than CIE and should be a useful addition to the diagnostic tests carried out on the CSF of any patient suspected of having meningitis.
