Survivorship of high tibial osteotomy in the treatment of osteoarthritis of the knee: a retrospective cohort study with fourteen years' follow-up. INTERNATIONAL ORTHOPAEDICS 2023:10.1007/s00264-023-05802-0. [PMID: 37039819 DOI: 10.1007/s00264-023-05802-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Accepted: 03/28/2023] [Indexed: 04/12/2023]
Abstract
PURPOSE This study was to evaluate the survivorship of HTO for the treatment of medial compartment osteoarthritis (OA) in young and active patients from two teaching hospitals in a single city. METHODS This is a retrospective cohort multicenter study looking at HTO for treatment of medial compartment OA. We analyzed a case series of HTO's performed by four surgeons in two centres over a 14-year period. Failure was defined as conversion to total knee replacement (TKR). All cases where additional procedures for instability of the knee were performed at the time of the index surgery were excluded. Time to failure was recorded, and a Kaplan-Meir (KM) analysis was performed to evaluate survivorship. Univariate binary regression analysis was undertaken to identify associations between risk factors and failure. RESULTS A total of 96 patients were included in the study with a median age was 45 years. The survivorship at five years post-op was 90.3%, and at ten years post-op, it was 82%. Patients that were 14 years after surgery had a survivorship of 65%. Also, 18.8% of patients required the removal of their metalwork. The overall complication rate was 6.3%. The univariate regression analysis showed that higher age (p = 0.02) and larger corrections requiring the use of bone graft increased the risk of failure (p = 0.02). There was no statistically significant correlation between laterality, gender, complication rate, and pre-operative alignment to survivorship. CONCLUSION This is one of the largest reported case series of HTO's with comparable survivorship at five and ten year follow-up compared to the reported literature. There was an association found between increasing age and larger corrections requiring bone graft at index procedure to increasing failure rate.

From Bumps to Binges: Overview of Deaths Associated with Cocaine in England, Wales and Northern Ireland (2000-2019). J Anal Toxicol 2023; 47:207-215. [PMID: 36611264 PMCID: PMC10037635 DOI: 10.1093/jat/bkad002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 11/24/2022] [Accepted: 01/05/2023] [Indexed: 01/09/2023] Open
Abstract
The UK, as the "cocaine capital of Europe," currently accounts for ∼75% of all cocaine-related hospital admissions in Europe. This study aims to analyze the trends in cocaine-related deaths in England, Wales and Northern Ireland over 20 years (2000-2019). Cases reported to the National Programme on Substance Abuse Deaths (NPSAD) occurring between 2000 and 2019 where cocaine was detected at post-mortem (PM) were extracted for analysis. A total of 5,339 cases were retrieved, with an increase in the rate of reporting over time. Cocaine was deemed a cause of death and quantified in PM blood samples along with its major metabolite benzoylecgonine in 685 cases. Of these 685 cases, 25% (n = 170/685) occurred following acute use, 22% (n = 154/685) following chronic/binge use, 40% (n = 271/685) in combination with morphine, 4% (n = 29/685) in drug packer/swallower circumstances and 9% (n = 61/685) in a suicide context. Cardiac complications were evident in 22% of cases (n = 154/685). The average concentration of cocaine detected in cardiac cases (900 ng/mL) was considerably lower than that detected in cases where acute (19,100 ng/mL) or chronic/binge (6,200 ng/mL) dosing was evident. This is the first cocaine-related mortality study in these geographical areas. Deaths following cocaine use continue to rise despite its Class A drug listing in the UK. While underlying and external risk factors including polydrug use, cardiac complications and mental health can all contribute to the incidence of fatal drug toxicity following cocaine use, this study demonstrates that the risk of a cocaine overdose cannot be attributed to a specific blood concentration range.

Development of a Gas-Tight Syringe Headspace GC-FID Method for the Detection of Ethanol, and a Description of the Legal and Practical Framework for Its Analysis, in Samples of English and Welsh Motorists' Blood and Urine. Molecules 2022; 27:molecules27154771. [PMID: 35897946 PMCID: PMC9331811 DOI: 10.3390/molecules27154771] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 07/14/2022] [Accepted: 07/17/2022] [Indexed: 11/30/2022] Open
Abstract
Ethanol is the most commonly used recreational drug worldwide. This study describes the development and validation of a headspace gas chromatography flame ionisation detection (HS-GC-FID) method using dual columns and detectors for simultaneous separation and quantitation. The use of a dual-column, dual-detector HS-GC-FID to quantitate ethanol is a common analytical technique in forensic toxicology; however, most analytical systems utilise pressure-balance injection rather than a simplified gas-tight syringe, as per this technique. This study is the first to develop and validate a technique that meets the specifications of the United Kingdom’s requirements for road traffic toxicology testing using a Shimadzu GC-2014 gas-tight syringe. The calibration ranged from 10 to 400 mg/100 mL, with a target minimum linearity of r2 > 0.999, using tertiary butanol as the internal standard marker. The method has an expanded uncertainty at 99.73% confidence of 3.64% at 80 mg/100 mL, which is the blood alcohol limit for drink driving in England and Wales. In addition, at 200 mg%—the limit at which a custodial sentence may be imposed on the defendant—the expanded uncertainty was 1.95%. For both the 80 mg% and 200 mg% concentrations, no bias was present in the analytical method. This method displays sufficient separation for other alcohols, such as methanol, isopropanol, acetaldehyde, and acetone. The validation of this technique complies with the recommended laboratory guidelines set out by United Kingdom and Ireland Association of Forensic Toxicologists (UKIAFT), the recently issued Laboratory 51 guidelines by the United Kingdom Accreditation Service (UKAS), and the criteria set out by the California Code of Regulations (CCR), 17 CCR § 1220.1.

Fracture liaison services in Ireland-how do we compare to international standards? Osteoporos Int 2022; 33:1089-1096.

Abstract
UNLABELLED In this first na tional survey of public hospitals in The Republic of Ireland, we found fracture liaison services (FLS) to be heterogeneous, limited in many cases and poorly supported. A national strategy is urgently needed to support the implementation and operation of an FLS, and thus help reduce the burden of fragility fractures for patients and the healthcare system. INTRODUCTION Fragility/low-trauma fractures are a global concern, whose incidence is rising as the population ages. Many are preventable, and people with a prior fragility fracture are at particularly high risk of further fractures. This patient group is the target of the International Osteoporosis Foundation (IOF) Capture the Fracture campaign, advocating global adoption of fracture liaison services (FLS), with the aim of preventing secondary fragility fractures. We wished to determine the current availability and standards of an FLS in Ireland, ahead of the launch of a National FLS database. METHODS We devised a questionnaire encompassing the thirteen IOF standards for an FLS and asked all 16 public hospitals with an orthopaedic trauma unit in Ireland, to complete for the calendar year 2019 in patients aged ≥ 50 years. RESULTS All sites returned the questionnaire, i.e. 100% response rate. Nine hospitals stated that they have an FLS, additionally one non-trauma hospital running a FLS responded, and were included. These 10 FLS had identified and managed 3444 non-hip fractures in the year 2019. This figure represents 19% of the expected non-hip fragility fracture numbers occurring annually in Ireland. Implementation of the IOF standards was very variable. All sites reported being inadequately resourced to provide a high-quality service necessary to be effective. CONCLUSION The existence and functioning of FLS in Ireland are heterogeneous and suboptimal. A national policy to support the implementation of this programme in line with international standards of patient care is urgently needed.

Near-infrared spectroscopy combined with chemometrics to classify cosmetic foundations from a crime scene. Sci Justice 2022; 62:327-335. [PMID: 35598925 DOI: 10.1016/j.scijus.2022.03.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 02/23/2022] [Accepted: 03/06/2022] [Indexed: 11/26/2022]
Abstract
Cosmetic smears are a form of trace evidence that can link the crime scene, suspects, and victims. Foundation and lipstick are the most common sources of cosmetics that can easily smear, with most current research focused on the evidential analysis of lipsticks. This research aims to create a database of cosmetic foundations on different materials and to access the robustness of using Near-infrared with chemometrics as a non-destructive technique to identify unknown samples collected from a crime scene. Small amounts of six shades of three brands of foundations were smeared on clothing materials, which were then analysed with a combination of Near-infrared with chemometric analysis. Principle component analysis (PCA) was used to reduce data dimensionality and explore potential patterns in sample separation and Linear Discriminant Analysis (LDA) was utilised to assign unknown samples to one of the established classes. The selected techniques proved to be promising for database construction and as a preliminary method of analysis, with 93% of the spectra being correctly classified. Notably, darker foundation shades were less likely to be correctly classified (90% classified correctly) compared to lighter ones (96.7% classified correctly). This could not be improved with Standard Normal Variate (SNV) data pre-treatment or selecting specific NIR regions. This finding is of particular importance; according to the Crime Survey for England and Wales (year ending March 2020) police recorded sexual offences demonstrated that those in Mixed and Black or Black British ethnic groups were significantly more likely to be a victim of sexual assault compared to White, Asian or Other ethnic groups. It is, therefore, crucial to add a wide range of foundation shades, particularly of darker tones, to the future database.

Metabolites of Cannabis Induce Cardiac Toxicity and Morphological Alterations in Cardiac Myocytes. Int J Mol Sci 2022; 23:ijms23031401. [PMID: 35163321 PMCID: PMC8835806 DOI: 10.3390/ijms23031401] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2022] [Revised: 01/12/2022] [Accepted: 01/19/2022] [Indexed: 12/18/2022] Open
Abstract
Cannabis is one of the most commonly used recreational drugs worldwide. Rrecent epidemiology studies have linked increased cardiac complications to cannabis use. However, this literature is predominantly based on case incidents and post-mortem investigations. This study elucidates the molecular mechanism of Δ9-tetrahydrocannabinol (THC), and its primary metabolites 11-Hydroxy-Δ9-THC (THC-OH) and 11-nor-9-carboxy-Δ⁹-tetrahydrocannabinol (THC-COOH). Treatment of cardiac myocytes with THC-OH and THC-COOH increased cell migration and proliferation (p < 0.05), with no effect on cell adhesion, with higher doses (250–100 ng/mL) resulting in increased cell death and significant deterioration in cellular architecture. Conversely, no changes in cell morphology or viability were observed in response to THC. Expression of key ECM proteins α-SMA and collagen were up-regulated in response to THC-OH and THC-COOH treatments with concomitant modulation of PI3K and MAPK signalling. Investigations in the planarian animal model Polycelis nigra demonstrated that treatments with cannabinoid metabolites resulted in increased protein deposition at transection sites while higher doses resulted in significant lethality and decline in regeneration. These results highlight that the key metabolites of cannabis elicit toxic effects independent of the parent and psychoactive compound, with implications for cardiotoxicity relating to hypertrophy and fibrogenesis.

Abstract
Ethanol is the most commonly encountered drug in forensic toxicology, with widespread use throughout society. For this reason, it is important that there are a variety of reliable and robust methods to detect and quantify the content of alcohol in blood samples of suspected drink drivers. A common method of detection is gas chromatography with flame ionisation detector, with a number of sample preparation techniques employed. Typically, venous blood is sampled and used in the analysis. However, there is currently no legal specification in the UK of the blood sample source. This study investigates the use of capillary blood as an alternative to venous blood alongside two different sample volumes: 100 and 10 µL. Venous and capillary blood were collected from volunteers who had consumed alcohol. All blood sampling was carried out one hour after cessation of drinking. The results show a statistically significant difference between venous and capillary samples, with an average difference of 3.38 ± 1.99 mg/100 mL at 100 μL and approximately 4.13 ± 2.42 mg/100 mL at 10 μL, respectively. Predominantly, venous blood was detected at higher concentrations than the corresponding capillary samples. The deviations in alcohol samples between venous and capillary blood are consistent with previous studies. However, our research indicates that capillary blood is a viable matrix to test for alcohol, albeit one that underestimates blood-alcohol content in relation to venous sampling. There was no statistically significant difference between the 100 and 10 µL sample preparation methods on an individual basis, which infers that micro-volumes of alcohol are suitable for forensic blood-alcohol analysis.

Toxicological Assessment of the Role of Alcohol and Drugs in Drug-Facilitated Sexual Assault Cases in New Zealand. J Anal Toxicol 2021; 45:44-52.

Abstract
This report details the toxicology profile of victims of drug-facilitated sexual assault (DFSA) in New Zealand from 2015 to 2018. This study represents all of the toxicology results for DFSA cases in New Zealand during this time period, of which there were 161 cases. Blood and urine samples were screened for legal and illicit drugs in addition to testing for alcohol and correlating alcohol concentration with sampling delay. Our results indicate that increased delay in sampling time resulted in a corresponding decrease in alcohol concentration. In victims who had declared alcohol use but of which none was detected, the average sampling time was 14 hours for blood and 17 hours for urine, which is in excess of the average sampling delay for even the lowest alcohol-positive samples. The most frequently detected alcohol concentration was in the range of 51-80 mg/100 mL for blood and 121-200 mg/100 mL for urine with an average sampling time of 8.5 and 6.5 hours, respectively. We also examined acetone concentrations in alcohol-positive samples, and our results indicate that 82% of blood alcohol-positive samples contained acetone at concentrations between 5 and 10 mg/L and 68% of alcohol-positive urine samples contained acetone at a concentration >20 mg/L. It may be that the nature of sexual assault affects an individual's metabolism of alcohol and results in increased acetone production. Cannabis was the most commonly detected illicit drug, followed by methamphetamine. In relation to medicinal drugs, there was a high usage of antidepressants and antipsychotics, suggesting the victims may have been people of vulnerable personality. Based on case information, it does not appear there are many cases where stupefaction by unknown administration of a drug has occurred, instead loss of consent through voluntary alcohol and drug consumption is more common and poses a greater risk than surreptitious drug administration.

Abstract
OBJECTIVES To investigate the impact of a six-month multi-ingredient nutrition supplement intervention (Smartfish®), containing omega-3 polyunsaturated fatty acids (PUFAs), vitamin D, resveratrol, and whey protein, on cognitive function in Irish older adults. DESIGN Double-blind, randomised controlled trial (ClinicalTrials.gov: NCT02001831). A quantitative, mixed-model design was employed in which the dependent variable (cognitive function) was analysed with a between-subjects factor of group (placebo, intervention) and within-subjects factor of testing occasion (baseline, three-months, six-months). SETTING Community-based intervention including assessments conducted at University College Dublin, Ireland. PARTICIPANTS Thirty-seven community-dwelling older adults (68-83 years; mean (x̄)= 75.14 years; standard deviation (SD)= 3.64; 18 males) with normal cognitive function (>24 on the Mini Mental State Examination) were assigned to the placebo (n= 17) or intervention (n= 20) via a block randomisation procedure. INTERVENTION Daily consumption for six-months of a 200mL liquid juice intervention comprising 3000mg omega-3 PUFAs [1500mg docosahexaenoic acid (DHA) and 1500mg eicosapentaenoic acid (EPA)], 10μg vitamin D3, 150mg resveratrol and 8g whey protein isolate. The placebo contained 200mL juice only. MEASUREMENTS A standardised cognitive assessment battery was conducted at baseline and follow-ups. Individual test scores were z-transformed to generate composite scores grouped into cognitive domains: executive function, memory, attention and sensorimotor speed. Motor imagery accuracy and subjective awareness of cognitive failures variables were computed from raw scores. RESULTS A hierarchical statistical approach was used to analyse the data; first, by examining overall cognitive function, then by domain, and then by individual test scores. Using mixed between-within subjects, analyses of variance (ANOVAs), no significant differences in overall cognitive function or composite cognitive domains were observed between groups over time. The only significant interaction was for Stroop Color-Word Time (p< 0.05). The intervention group demonstrated reduced task completion time at three- and six-month follow-ups, indicating enhanced performance. CONCLUSION The present nutrition intervention encompassed a multi-ingredient approach targeted towards improving cognitive function, but overall had only a limited beneficial impact in the older adult sample investigated. Future investigations should seek to establish any potential clinical applications of such targeted interventions with longer durations of supplementation, or in populations with defined cognitive deficits.

Cocaine addicted to cytoskeletal change and a fibrosis high. Cytoskeleton (Hoboken) 2019; 76:177-185.

Abstract
Cocaine is one of the most widely abused illicit drugs due to its euphoric and addictive properties. Cocaine-mediated cognitive impairments are the result of dynamic cytoskeletal rearrangements involved in mediating structural and behavioural plasticity. Cytoskeletal changes initiated following cocaine abuse are regulated by the Rho family of GTPases with significant downstream activity in key actin binding proteins. Moreover, signalling via the endoplasmic reticulum chaperone protein, sigma-1 receptor has highlighted the possibility of cocaine regulated pathology in other organ systems. However, the question of whether upstream stimulation of such a high affinity binding receptor is directly involved in cocaine-mediated cytoskeletal changes at present remains unknown. In this review, we describe the functional role of key cytoskeletal regulators in response to cocaine-induced signalling cues. In addition, we ascertain the extent of whether global cytoskeletal modulators involved in cocaine-induced neurological stimulation can be used as a platform for future studies into elucidating its fibrotic potential within the hepatic microenvironment. A focus on aspects still poorly understood relating to the nonneuronal pathological impact of cocaine is discussed in the sphere of hepatic dysregulation. Lastly, we suggest that cocaine may mediate its pathological capacity via the sigma1 receptor in regulating hepatoxicity, hepatic stellate cells activity, cytoskeletal dynamics, and the transcriptional regulation of key hepato-fibrogenic modulators.

Abstract
This report details the blood concentration of drugs found in motorists suspected of driving under the influence of drugs from 2010 to 2012 in England and Wales. This study was carried out as new legislation has come into place, setting fixed blood concentration limits for drugs in motorists. These include a cannabis (Δ9-THC) blood concentration of 2 µg/L, amphetamine 250 µg/L, benzoylecgonine (BZE) 50 µg/L, cocaine 10 µg/L, 6-monoacetylmorphine 5 µg/L, morphine 80 µg/L, diazepam 550 µg/L and methadone 500 µg/L. Samples were screened for opiates, methadone, benzodiazepines, cannabinoids, cocaine, amphetamines and methamphetamine. Cannabinoids were the most prevalent drug group (29.7%) followed by benzodiazepines (22.7%), opiates (18.8%), cocaine (16.3%), amphetamine (7%) and methadone (5.6%). The analytical results are compared with the new per se limits to give a reference of drug concentrations prior to this legislation coming into effect. Our studies show that 64.9% of the cannabis samples, 59.1% of the cocaine samples and 94.6% of the BZE samples would be above the new per se limits set under Section 5a of the Road Traffic Act. In contrast, the medicinal drugs such as benzodiazepines and opiates (morphine) were predominantly detected at concentrations below the new per se limit. Given its medical applications, amphetamines appear to have been grouped with the medicinal type drugs, with our data showing that 25.2% of the amphetamine positive samples would exceed the new specified limit. These data show that samples containing medicinal and prescription drugs are likely to be detected below the new legal limits, while illicit drugs were typically found at concentrations above the new specified limits.

Abstract
Thirty-five unstable dorsally displaced fractures of the distal radius in 34 patients (mean age 39) were studied; 28 fractures were intra-articular. All fractures had open reduction and fixation, through a dorsal approach, with mini-fragment plates placed between the first and second dorsal tendon compartments and deep to the fourth compartment. A congruous reduction of the articular surface was obtained in all cases. Twenty-four patients were available for follow-up (median 38 months). The Modified Mayo wrist score was excellent in 12 cases, good in four, and fair in eight. The median Patient Evaluation Measure score was 23.5. There were no cases of extensor tendon rupture. Radiographic assessment at follow-up showed a mean palmar angle of 6 degrees. There was evidence of osteoarthritis in six patients who had had intra-articular fractures. Open reduction and plating gives satisfactory medium term results for treatment of displaced intra-articular fractures of the distal radius in young patients.

OBJECTIVE To determine the current level of use, referral and desire for service of different complementary and alternative (CAM) therapies among Gundersen Lutheran Medical Center providers. METHODS A survey was conducted in January of 2001 of all medical and associate staff. RESULTS The response rate was 79%; 55% reported using 1 or more of 18 therapies for themselves. Over 25% of providers used nutritional supplements, herbal medicines, or hydrotherapy with a patient. Over half of providers had referred a patient for biofeedback or chiropractic care. Over half of providers would like to offer acupuncture, biofeedback, chiropractic care, hydrotherapy, nutritional supplements, or massage to patients in the future. Associate staff, female staff, primary care providers, and those who had personally used CAM therapies were more likely to have used, referred, or wish to offer more therapies in the future. There was little support for aromatherapy, magnetic field therapy, naturopathic medicine, or ethnic healing methods. CONCLUSIONS Use of and desire for complementary therapies at Gundersen Lutheran was higher than expected by the Integrative Medicine Oversight Committee. Health care organizations should consider having a process in place to manage the increasing demands for complementary and alternative therapies.

Abstract
OBJECTIVES To investigate the extent to which compliance with treatment is related to outcome, and factors associated with compliance in a group of treatment-resistant eating-disordered in-patients. DESIGN A retrospective case study design was employed where clinic staff made expert ratings of eating behaviours, attitudes and outcome of former in-patients. METHOD Ten health-care staff at a specialist eating disorders clinic rated overall success of treatment outcome at discharge, as well as compliance, severity of disordered eating behaviours and body-image disturbance at both admission and discharge for 46 anorexic and 14 bulimic patients. RESULTS For all participants, high compliance at admission was associated with lower levels of body image disturbance, less disordered eating behaviours and higher ratings of overall treatment success at discharge. Compliance at admission predicted the body mass index (BMI) at discharge for anorexic participants and predicted higher ratings of overall treatment success at discharge for all participants. In all participants, compliance at admission was related to the extent of eating-disordered behaviours at admission. CONCLUSIONS Results suggest the importance of compliance in facilitating recovery and treatment success among treatment-resistant eating-disordered in-patients. The promotion of strategies to improve compliance in this population should be considered. A role for motivational interviewing is discussed.

Abstract
OBJECTIVE To examine the hypothesis that functional ability is related to skin score in patients with systemic sclerosis (SSc). METHODS In 140 patients with SSc attending clinics in the northwestern region of England, functional ability (measured using a recently developed 11 item functional questionnaire) was correlated with skin score (measured using a modified Rodnan technique--17 sites, maximum score 3 for each site). RESULTS The median functional score was 6 (range 0-31) and the median skin score 7 (range 0-37). There was no correlation between functional score and total skin score (rS = 0.11, p = 0.19, Spearman). Because most of the questions of the functional score related to upper limb function, separate analyses were undertaken restricting consideration of skin involvement to (1) upper limbs only and (2) digital skin only, versus the overall functional score. Again, no evidence of an association was observed. CONCLUSION Functional ability in this broad group of patients with SSc cannot be predicted from the skin score. Although skin score is useful prognostically, it is not a major determinant of a patient's ability to perform activities of everyday living.

Abstract
BACKGROUND The Community Mothers Programme aims at using experienced volunteer mothers in disadvantaged areas to give support to first-time parents in rearing their children up to 1 year of age. The programme was evaluated by randomized controlled trial in 1990. METHODS Seven years later, trial participants were interviewed about child health, nutrition, cognitive stimulation, parenting skills, and maternal self-esteem. The aim of this study was to see whether the demonstrated benefits at 1 year of age of this programme could be sustained at age 8. RESULTS One-third of the original group (38 intervention, 38 control), were contacted and interviewed. The risk for having an accident requiring a hospital visit was lower in the intervention group: relative risk (RR) 0.59, 95 per cent confidence interval (CI) 0.31-1.11. Intervention children were more likely to visit the library weekly: RR 1.58, 95 per cent CI 1.10-2.26. Intervention mothers were more likely to check homework every night: RR 1.23, 95 per cent CI 1.05-1.43 (p=0.006); and to disagree with the statement 'children should be smacked for persistently bad behaviour': RR 2.11, 95 per cent CI 1.10-4.06. They were more likely to disagree with the statement 'I do not have much to be proud of': RR 1.24, 95 per cent CI 1.04-1.40; and to make a positive statement about motherhood than controls: RR 1.53, 95 per cent CI 1.06-2.20. Subsequent children of intervention mothers were more likely to have completed Haemophilus influenzae b: RR 1.26, 95 per cent CI 1.06-1.51; and polio immunization: RR 1.19, 95 per cent CI 1.02-1.40. CONCLUSIONS The Community Mothers programme had sustained beneficial effects on parenting skills and maternal self-esteem 7 years later with benefit extending to subsequent children.

Abstract
OBJECTIVE To examine bone density in 19 women who had previously experienced classical anorexia nervosa from which they had been fully recovered for a mean of 21 years (current characteristics: median age 40.2 years; Eating Attitudes Test [EAT] score 2; body mass index [BMI] 21.1; average 1.8 offspring). METHOD Probands were compared, blindly, in respect of bone density, with 13 control subjects matched for age and sex and with no history of eating disorders. Dual energy X-ray absorptiometry (DXA) was used to evaluate the bone mineral density (BMD) of the lumbar spine and the head of the femur. RESULTS Femur BMD was still significantly less among ex-anorectic sufferers. Two subjects had experienced pathological fractures while anorectic, both having been strenuous exercisers. None appeared to have suffered post illness fractures. BMD at follow-up did not relate to the severity or chronicity of previous anorexia nervosa. DISCUSSION Full clinical recovery from anorexia nervosa does not quite confer full establishment of normal bone density. However, pathological fractures are not a feature thereafter, within middle life.

Abstract
A variety of gene therapy strategies are under development for the treatment of sickle cell anemia and other hemoglobinopathies. A number of alternative vectors have been developed to transfer and express the beta-globin gene and other therapeutic molecules, but none has resulted in efficient transduction and stable long-term expression in primary hematopoietic cells. One reason for this problem is that most vectors are initially evaluated in immortalized cell lines which may not faithfully recapitulate the biology of primary erythroid cells. In order to provide a more relevant system for efficiently evaluating alternative vector constructs for beta-globin disorders, we have developed (1) a simple method for generating primary human red blood cell (RBC) precursors in liquid culture established with mononuclear cells obtained from normal donors as well as patients with Hb SC disease; (2) a high titer retroviral vector which can be easily modified to optimize gene transfer and transgene expression; and (3) methods for transducing the RBC precursors at high efficiency. The development of simple and efficient methods and reagents for generating and transducing primary human RBC precursors provides a facile and effective means for screening alternative gene therapy strategies. Gene Therapy (2000) 7, 215-223.

Abstract
BACKGROUND Most reports regarding the treatment of thyroid cancer originate from university referral centers. In this article, we report our experience in managing thyroid cancer of follicular cell origin at a non-university institution over a 26-year period. STUDY DESIGN We reviewed the medical records of all patients treated for thyroid cancer at the Gundersen/Lutheran Medical Center from 1969 to 1995. Histologic types, demographic and clinical characteristics, laboratory results, treatment, complications, and followup observations were tabulated. Risk was assigned according to the age, presence of distant metastasis, extent of the primary tumor, and site of the primary tumor (AMES) staging system. RESULTS The histologic classification was as follows: papillary, 139; follicular, 24; Hürthle cell, 14; and anaplastic, 11. Low-risk lesions were identified in 96%, 79%, and 71% of the patients with papillary, follicular, and Hürthle cell (collectively designated differentiated) carcinoma, respectively. We treated 60% of our patients with differentiated thyroid cancer with near-total or total thyroidectomy. Clinically involved cervical lymph nodes were removed singly or by modified neck dissection. We frequently ablated thyroid remnants after operation with 29.9 mCi (1,110 MBq) of 131I, after which we treated the patient with suppressive doses of levothyroxine. Patients were evaluated yearly with thyroglobulin measurements and, in some high-risk patients, with total-body 131I scans. Cancer recurred in 13%, 8%, and 7% of our patients with papillary, follicular, and Hürthle cell carcinoma, respectively. Only three patients died of differentiated thyroid cancer; eight are alive with malignancy. In anaplastic thyroid cancer, cervical lymph node metastases, local invasion, and distant metastases were present in 18%, 64%, and 45% of patients at the time of initial evaluation. Total or near-total thyroidectomy was possible in only four of nine patients treated surgically. External radiation (11 patients) and chemotherapy (two patients) were used. Additional metastases developed in 45% of the patients, and nine patients died within a year. Permanent hypoparathyroidism or hoarseness complicated 2.7% of the thyroid operations. CONCLUSIONS Although our followup was relatively short, the results of treating thyroid cancer by general surgeons at a nonuniversity hospital compare favorably with results obtained from university referral centers.

Abstract
OBJECTIVE To determine incidence and prevalence of anorexia nervosa in a defined geographical area of south west London, UK, total population 519,900. METHOD Hospital and community health workers in the defined area were contacted initially by letter asking them to identify all cases (new or existing) of anorexia nervosa known to them in the period July 1991-June 1992, using DSM-III-R criteria. A semistructured interview was conducted with the respondents to confirm the diagnosis. The large database record of the senior authors' specialist anorexia nervosa service, including inpatient and outpatient service records, was concurrently screened for cases living in the defined area. RESULTS The prevalence of anorexia nervosa was found by this method to be 20.2 cases per 100,000 population (0.02% total population). Prevalence in females aged 15-29 years was 115.4 cases per 100,000 (0.1% of young females). Similarly, the annual incidence of anorexia nervosa was found to be 2.7 cases per 100,000 total population. In females aged 15-29 years the incidence was 19.2 cases per 100,000. DISCUSSION Such prevalence and incidence figures are probably significant underestimates since the disorder can often defy detection or correct diagnosis and, with our own methodology, some identified cases may not have been reported to the study. However, these results can be used as a start for resource planning and service development.

Abstract
PURPOSE In order to reduce the risk of major anesthetic complications associated with laparoscopic gamete intrafallopian transfer procedures, we have exclusively used thin-needle spinal anesthesia over the years 1991 - 1994. This paper will review complication rates in order to further establish the safety profile of GIFT under thin-needle anesthesia and report the changes in our GIFT protocol from 1991 to 1994 which have been associated with a statistical improvement in the implantation rate from 11% to 23% (P = 0.01) and an increase in delivery rates from 29% to 42% per transfer procedure. METHODS Sixty-eight laparoscopic GIFT procedures were done in women with at least one patent oviduct and failure to respond to less invasive treatment. Clinical variables were analyzed to determine if similar patient populations had been treated over the study period. RESULTS The improved delivery rates and implantation rates could not be explained by patient selection. No major perioperative complications occurred. Minor perioperative complications and difficulties included one patient requiring general anesthesia, one patient developing a spinal headache which could be managed conservatively at home, and one patient requiring a minilaparotomy to complete the GIFT procedure. The more serious complications occurred as a result of the superovulation and multiple oocyte transfer rather than the surgical or anesthetic technique. These included two patients with severe ovarian hyperstimulation requiring hospitalization, and five delivered triplet pregnancies. Factors associated with improving success rates included improvements in semen and equipment preparation as well as an increase in the number of sperm transferred from 200,000 to 500,000. CONCLUSIONS GIFT can be performed with relative safety under thin needle spinal anesthesia with high implantation and delivery rates if care is made to optimize sperm and equipment preparation. GIFT under thin-needle spinal anesthesia may be an attractive alternative for treatment of longstanding nontubal infertility in couples willing to take the risk of ovarian hyperstimulation and multiple pregnancy.

Abstract
The role of ultrasound in the diagnosis of prostate cancer is still evolving. We used ultrasound to examine 202 patients with palpably abnormal prostates. Of 151 patients undergoing biopsy, ultrasound-guided biopsy was comparable to digitally directed biopsies in cancer detection (92% vs 90.7%). The two methods are complementary and should both be considered in patients with palpably abnormal prostates.

Abstract
This article reviews the one-year experience (March 28, 1987 to March 27, 1988) of the pediatric transport service of the University of Wisconsin Hospital and Clinics (UWHC). The UWHC pediatric transport team consisted of a critical care flight nurse and a pediatric critical care attending physician or fellow. The aims of the study were to: 1) determine the types and number of interventions performed by the physicians to gauge the need for physician presence on transport; and 2) determine which variables (severity of illness scores, age, gender, distance from hospital) recorded at the time of the referral telephone call best predicted outcome of the patient. There were 109 children transported by helicopter during the one-year study period. Thirty percent of the patients (43% of trauma patients and 22% of medical patients) had no interventions at all, 18% of medical patients and 10% of trauma patients were intubated, and 9% of medical patients and no trauma patients had central venous catheters inserted. Multivariate modeling determined that among medical patients, outcome could be accurately predicted only 38% of the time if telephone PRISM (Pediatric Risk of Mortality) scores were determined. Among trauma patients, if gender, age, distance from UWHC, and telephone PRISM scores were known, outcome could be predicted 74% of the time. Unless studies show the benefit of pediatrician-accompanied transport, transports could probably be done without critical care pediatricians. Severity of illness scoring at this time is probably not sufficiently accurate to warrant its use for deciding the appropriateness of transport of pediatric patients.

Abstract
The alpha- and beta-subunits of the receptor for platelet-derived growth factor (PDGFR) were found to be autophosphorylated in the absence of ligands at high expression levels which suggests a propensity of PDGFRs to dimerize spontaneously. When the extracellular domains (ED) of both receptors were expressed and purified to homogeneity, they could be dimerized specifically by the different PDGF isoforms. PDGF-BB-induced dimerization was dependent on uncleaved loop I sequences present on both chains. Whereas, in solution, the EDs were weak competitors for PDGF binding to cellular PDGFRs, they formed high and low affinity complexes upon immobilization on solid phase. Cross-competition experiments defined two distinct binding sites on PDGFR alpha-ED. PDGF-AB bound only to the low affinity form of immobilized PDGFR beta-ED and could not dimerize PDGFR beta-ED. Cross-linking studies, however, revealed that both chains of PDGF-AB can interact with a PDGFR beta-ED monomer. Cross-linking of PDGF homodimers with EDs also yielded complexes which contained more than two ligand chains. These results led to a revised model of receptor-ligand interaction and indicate that monomeric PDGF should be able to dimerize PDGF receptors.

Abstract
OBJECTIVE To analyze reproductive outcome after laparoscopic procedures for ectopic pregnancy, with particular attention to laparoscopic salpingectomy. METHODS In a 260-physician multispecialty clinic in the rural upper midwestern United States, 143 patients were followed prospectively after undergoing laparoscopic procedures for ectopic pregnancy. Ninety-five who sought further pregnancies during the study period were analyzed for reproductive outcome. Intrauterine pregnancy rates were compared by age, parity, size of ectopic gestation, and evidence of prior tubal damage. Life table analysis was also performed. RESULTS The overall intrauterine pregnancy rates for laparoscopic salpingostomy (60%) and laparoscopic salpingectomy (54%) were not significantly different from each other. However, intrauterine pregnancy rates differed significantly by history of prior tubal damage. The pregnancy rate was 79% among women without tubal damage and 42% among women with damage. CONCLUSIONS Our intrauterine pregnancy rates after both laparoscopic salpingectomy and laparoscopic salpingostomy are similar to those reported in the literature for similar procedures performed at laparotomy. In predicting pregnancy outcome after laparoscopic procedures for ectopic pregnancy, the major variable seemed to be evidence of prior tubal damage. With no evidence of previous damage, we found similarly high pregnancy rates for laparoscopic salpingostomy and salpingectomy.

Abstract
A random mailed survey (response N = 226; 75.3%) of participants in diet-related home-based learning evaluated exposure to recruitment channels and impact on salience, utility, level of participation, sharing the course with others, knowledge, and performing recommended behaviors. A post-only design, the study was conducted in a small Minnesota city (population = 20,000), part of the Cancer and Diet Intervention (CANDI) project. About 18.5% of residents (3,711) enrolled during an 8-week media campaign; women, college graduates, and those over 44 years old were overrepresented. Participants learned about the program through mass media (97%); small media (41.9%); and interpersonal sources (50%). Women were more likely to learn about the course through interpersonal sources. In analysis of variance (ANOVA) modeling, salience and utility predicted level of participation in course activities. Level of participation in turn predicted nutrition knowledge and with salience predicted performance of recommended behaviors. Although the course appealed to individuals who needed it less, there was evidence of diffusion to the unenrolled. About 57% of responding participants reported sharing it with spouses; about 67% reported sharing it with someone outside their households.

Abstract
Public support for policies to control alcohol sales and consumption was surveyed in seven Minnesota communities. A total of 438 women and 383 men were asked to indicate their level of support of or opposition to nine different proposals designed to regulate alcohol. There was general support for all policies, which was strongly related to characteristics of respondents and type of policy proposed. Women were significantly more supportive of all items than were men. Marriage, older age and low alcohol consumption were also associated with support. Education and voter status generally were not. Policies and activities that serve primarily to protect youth received the strongest support. Restrictions and prohibitions such as limiting advertisements were less popular. The least support was expressed for increases in taxes on alcohol and for measures that would eliminate an existing practice such as prohibiting wine-cooler sales at convenience stores. The majority of respondents also indicated that they felt the individual, as opposed to the manufacturer or retailer, was responsible for problems associated with alcohol and should be the focus of intervention. Strategies for shifting the focus from the individual to environmental and regulatory control are discussed.

Abstract
We analyzed data obtained from a representative sample of the smoking patients (n = 1,338) of 66 family physicians to determine predictors of attempts to stop smoking, desire to quit smoking, and successful smoking cessation. Compared to subjects who made no attempt to quit smoking, subjects who tried to quit smoking tended to be younger, had tried to quit smoking in the year prior to the study, waited longer before smoking their first cigarette of the day, had more desire to quit smoking, and had more social support for quitting. Education and cigarettes smoked per day were not independently related to the subject making a quit attempt. Desire to quit smoking was associated with an attempt to quit in the year prior to the study and social support for smoking cessation (support of spouse, second most important social contact, and physician). Desire to quit smoking was not independently related to age, education, or dependency on cigarettes (measured by the number of cigarettes smoked per day and the length of time a subject waited before smoking the first cigarette of the day). Compared to subjects who tried to quit and failed, subjects who succeeded were older, smoked fewer cigarettes per day, and waited longer to smoke their first cigarette of the day. Spouse support, support of the second most important social contact, and advice of a doctor to quit smoking were not independently related to whether or not a cessation attempt would be successful. These data suggest that successful smoking cessation requires two components: social support to make an attempt to quit and the ability to overcome dependency on cigarettes to make the attempt successful.

Abstract
Public support of eight policies to regulate the sale and consumption of high-fat food was evaluated in a survey of 438 women and 383 men in seven Minnesota communities. The survey was part of the ongoing activities of the Minnesota Heart Health Program (MHHP). Respondents, when asked to indicate their level of support or opposition to each of eight policies, expressed general support for all but two. Women were consistently more supportive than men. Other sociodemographic characteristics and reported use of food and other substances were generally not predictive of support. Policies that would control conditions of sale or information about the product were the most strongly supported. Taxation as an incentive to food producers to provide alternatives to high-fat food or as a disincentive to consumers to purchase these foods was moderately supported. A proposal to limit sale of high-fat food to children was the most strongly opposed. The majority of respondents indicated that they felt the individual consumer, as opposed to the producer or retailer, is most responsible for problems associated with high-fat food use. The three communities which had received MHHP health promotion activities were significantly more supportive than the comparison communities on two of the eight proposals. There is a moderate level of support in the general public for additional policies to regulate the sale and consumption of high-fat foods. These policy level interventions, similar to policies common in the regulation of alcohol and tobacco use, may be a feasible strategy to help moderate use of potentially health-compromising food products.
