Health service utilization for eating disorders: Findings from a community-based study,

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 5 2007
Jonathan M. Mond PhD
Abstract Background: Prior use of health services was examined in a community sample of women with bulimic-type eating disorders. Method: Participants (n = 159) completed a structured interview for the assessment of eating disorder psychopathology as well as questions concerning treatment-seeking and type of treatment received. Results: Whereas a minority (40.3%) of participants had received treatment for an eating problem, most had received treatment for a general mental health problem (74.2%) and/or weight loss (72.8%), and all had used one or more self-help treatments. Where treatment was received for an eating or general mental health problem, this was from a primary care practitioner in the vast majority of cases. Only half of those participants who reported marked impairment associated with an eating problem had ever received treatment for such a problem and less than one in five had received such treatment from a mental health professional. Conclusion: Women with bulimic-type eating disorders rarely receive treatment for an eating problem, but frequently receive treatment for a general mental health problem and/or for weight loss. The findings underscore the importance of programs designed to improve the detection and management of eating disorders in primary care. © 2007 by Wiley Periodicals, Inc.

Phenol-Castor Oil: Modified Peel for Dermal Melasma

DERMATOLOGIC SURGERY, Issue 5 2006
THADA PIAMPHONGSANT MD
BACKGROUND Deep type of melasma is difficult to treat. Various compositions for peeling have been formulated to accomplish this. OBJECTIVE Our purpose was to determine the safe use of the new formula, which was composed of phenol and castor oil. METHODS Different concentrations of phenol and castor oil were mixed in five formulations, and the solutions were tested on the forearms of 10 volunteers. The application time was 1 minute, different from that of the original phenol-croton oil. Formula 4 was found to cause a high effect of peeling with least side effects and was used to treat deep facial melasma in 30 patients. RESULTS Higher concentrations of castor oil produced more inflammation when mixed with phenol. Formula 4 was used to clear two cases of melasma in 1 week despite no effect from prior use of a modified antimelasma cream, while some degree of fading was noted in other cases. The total number of different melasma indices was reduced from 206.4 to 91.2 in 30 patients. Hyperpigmentation was noted in five cases and hypopigmentation in one case. Neither scar formation nor cardiac arrhythmia was observed. CONCLUSION A phenol-castor oil peel with an application time of 1 minute reduces pigments in the deep type of melasma with least side effects and a high efficiency when combined with an antimelasma cream. The safe formula and the technique of application are introduced. [source]


Persistence of drug use during imprisonment: relationship of drug type, recency of use and severity of dependence to use of heroin, cocaine and amphetamine in prison

ADDICTION, Issue 8 2006
John Strang
ABSTRACT Aim To investigate the persistence of use of heroin, cocaine and amphetamine drugs during imprisonment, and to identify factors associated with increased levels of persistence. Design The use of heroin, cocaine and amphetamine by current prison inmates has been examined and, in particular, the relationship between drug use within prison and the type of drug used prior to imprisonment, recency of use and severity of dependence., Setting and participants A randomly selected sample of 1009 adult male prisoners in 13 prisons in England and Wales during 1994/95; structured confidential interviews conducted by independent research staff. Enquiry about prior use of heroin, cocaine or amphetamine focused on three time-periods (ever, last year and last month pre-prison) and the use of these drugs during the first month of imprisonment. Findings A total of 557 (55%) of the 1009 prisoners had used previously one of the three drugs selected for study: 58% had used heroin, 69% cocaine and 75% amphetamine. More than half (59%; 327/557) had used these drugs in the month before the current imprisonment. Drug use in prisons was most likely to occur among those who had used in the month prior to imprisonment. The persistence of heroin use in prison occurred more frequently (70%) than use of cocaine (20%) or amphetamine (15%). Of those using heroin pre-imprisonment, 67% considered they were dependent, compared to 15% and 22%, respectively, for cocaine and amphetamine users. Conclusions Changes in the drug-taking behaviour of drug users after imprisonment vary according to the type of drug being taken. Prisoners were much more likely to continue to use heroin than either cocaine or amphetamines while in prison. Heroin was most likely to be used by those who had been using heroin during the immediate pre-imprisonment period, and particularly by the two-thirds of heroin users who considered themselves dependent. In view of the high prevalence of prior use of these drugs by individuals currently imprisoned, continuing attention is required to study of their behaviour and of the impact of interventions that may be introduced during or following their incarceration.

The application of computer touch-screen technology in screening for psychosocial distress in an ambulatory oncology setting

EUROPEAN JOURNAL OF CANCER CARE, Issue 4 2002
A. ALLENBY DN, MEDST
The objective of the study was to evaluate the acceptability and feasibility of computer touch-screen technology as a method for patients to report psychosocial functioning in an ambulatory cancer clinic. Patients participating in a randomized trial evaluating the use of self-reported psychosocial information in the clinical encounter were surveyed. The patients completed the Cancer Needs Questionnaire (CNQ), European Organization for the Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ-C30) and the Beck Depression Inventory , Short Form (BDI) using a touch-screen computer. The time taken to complete the questionnaires was recorded electronically. Patients completed a seven-item pen and paper survey to assess acceptability of the process. Of the 450 patients, 244 (54%) were 60 years or older. Although over half the patients had no prior computer experience, nearly all found the touch screen easy to use and the instructions easy to understand. Each question was answered by at least 447 (99.3%) patients. The average time to complete the CNQ was 9.1 min, EORTC QLQ-C30 4.0 min and BDI 3.1 min. Factors influencing time to completion were prior use of computers, physical condition, education and overall level of needs. The study found that the use of computer touch-screen technology is an acceptable and efficient method for obtaining self-reported information on quality of life, cancer needs and psychological distress.

Risk Segmentation Related to the Offering of a Consumer-Directed Health Plan: A Case Study of Humana Inc.

HEALTH SERVICES RESEARCH, Issue 4p2 2004
Laura A. Tollen
Objective. To determine whether the offering of a consumer-directed health plan (CDHP) is likely to cause risk segmentation in an employer group. Study Setting and Data Source. The study population comprises the approximately 10,000 people (employees and dependents) enrolled as members of the employee health benefit program of Humana Inc. at its headquarters in Louisville, Kentucky, during the benefit years starting July 1, 2000, and July 1, 2001. This analysis is based on primary collection of claims, enrollment, and employment data for those employees and dependents. Study Design. This is a case study of the experience of a single employer in offering two consumer-directed health plan options ("Coverage First 1" and "Coverage First 2") to its employees. We assessed the risk profile of those choosing the Coverage First plans and those remaining in more traditional health maintenance organization (HMO) and preferred provider organization (PPO) coverage. Risk was measured using prior claims (in dollars per member per month), prior utilization (admissions/1,000; average length of stay; prescriptions/1,000; physician office visit services/1,000), a pharmacy-based risk assessment tool (developed by Ingenix), and demographics. Data Collection/Extraction Methods. Complete claims and administrative data were provided by Humana Inc. for the two-year study period. Unique identifiers enabled us to track subscribers' individual enrollment and utilization over this period. Principal Findings. Based on demographic data alone, there did not appear to be a difference in the risk profiles of those choosing versus not choosing Coverage First. However, based on prior claims and prior use data, it appeared that those who chose Coverage First were healthier than those electing to remain in more traditional coverage. For each of five services, prior-year usage by people who subsequently enrolled in Coverage First 1 (CF1) was below 60 percent of the average for the whole group. Hospital and maternity admissions per thousand were less than 30 percent of the overall average; length of stay per hospital admission, physician office services per thousand, and prescriptions per thousand were all between 50 and 60 percent of the overall average. Coverage First 2 (CF2) subscribers' prior use of services was somewhat higher than CF1 subscribers', but it was still below average in every category. As with prior use, prior claims data indicated that Coverage First subscribers were healthier than average, with prior total claims less than 50 percent of average. Conclusions. In this case, the offering of high-deductible or consumer-directed health plan options alongside more traditional options caused risk segmentation within an employer group. The extent to which these findings are applicable to other cases will depend on many factors, including the employer premium contribution policies and employees' perception of the value of the various plan options. Further research is needed to determine whether risk segmentation will worsen in future years for this employer and if so, whether it will cause premiums for more traditional health plans to increase.

The development of a facet analysis system to identify and measure the dimensions of interaction in online learning

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 11 2007
Shawne D. Miksa
The development of a facet analysis system to code and analyze data in a mixed-method study is discussed. The research goal was to identify the dimensions of interaction that contribute to student satisfaction in online Web-supported courses. The study was conducted between 2000 and 2002 at the Florida State University School of Information Studies. The researchers developed a facet analysis system that meets S. R. Ranganathan's (1967) requirements for articulation on three planes (idea, verbal, and notational). This system includes a codebook (verbal), coding procedures, and formulae (notational) for quantitative analysis of logs of chat sessions and postings to discussion boards for eight master's level courses taught online during the fall 2000 semester. Focus group interviews were subsequently held with student participants to confirm that results of the facet analysis reflected their experiences with the courses. The system was developed through a process of emergent coding. The researchers have been unable to identify any prior use of facet analysis for the analysis of research data as in this study. Identifying the facet analysis system was a major breakthrough in the research process, which, in turn, provided the researchers with a lens through which to analyze and interpret the data. In addition, identification of the faceted nature of the system opens up new possibilities for automation of the coding process. [source]


Novel corrective equations for complete estimation of human tissue lipids after their partial destruction by perchloric acid pre-treatment: high-resolution 1H-NMR-based study

NMR IN BIOMEDICINE, Issue 2 2008
Niraj Kumar Srivastava
Abstract Owing to the small quantity of tissue available in human biopsy specimens, aqueous and lipid components often have to be determined in the same tissue sample. Perchloric acid (PCA) used for the extraction of aqueous metabolites has a deleterious effect on lipid components; the severity of the damage is not known. In this study, human muscle tissue was first treated with PCA to extract aqueous metabolites, and the residue was then used for lipid extraction by conventional methods, i.e. the methods of Folch and Bligh & Dyer and a standardised one using methanol/chloroform (1:3, v/v) used in our laboratory. A 1H-NMR spectrum was obtained for each lipid extract. Lipid was quantified by measuring the integral area of N+ -(CH3)3 signals of phospholipids (PLs). Triacylglycerol (TG) and cholesterol (CHOL) were quantified using the -CH2 - signals of glycerol and the C18 methyl signal, respectively. This study shows that prior use of PCA caused marked attenuation of TG, PL, and CHOL. This was confirmed by recovery experiments and observation of the direct effect of PCA on the standard lipid components. On the basis of the quantity of lipid lost in each case, three novel equations (with respect to TG, PL, and CHOL) were derived. Application of these equations to lipid quantities estimated in different pathological tissues after PCA pre-treatment produced values equivalent to those estimated without PCA use. This study conclusively shows that PCA pre-treatment damages all three lipid moieties, TG, PL, and CHOL. When PCA is used in a fixed ratio to the tissue, the lipid damage is also proportional and correctable by statistically derived equations. These equations will be useful in human biopsy specimens where aqueous and lipid components have to be studied using the same tissue sample because of the small quantity available.

Treatment with inhaled corticosteroids in asthma is too often discontinued,

PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 4 2008
Nancy S. Breekveldt-Postma PhD
Abstract Purpose To study persistence with inhaled corticosteroids (ICS) and its determinants in asthma-patients. Methods From the PHARMO database, asthma-patients (age,<,35 years) with a first dispensing for ICS in 1999,2002 and,,,2 dispensings in the first year were included. Persistence during the first year was defined as the number of days from start to time of first failure to continue renewal of the initial ICS. Potential determinants of persistence were assessed at ICS-start and 1 year before. Results The study-cohort included 5563 new users of single ICS and 297 of fixed-combined ICS. Less than 10% of patients using single ICS and 15% of patients using fixed-combined ICS were persistent at 1 year. Similar persistence-rates were observed when stratified for age (children/adolescents: 0,18 years and adults: 19,34 years). Increased persistence with single ICS was observed with the type of ICS (budesonide), prescriber (specialist), prior use of long-acting beta-agonists, previous hospitalization for asthma, metered-dose inhaler, low starting-dose and once-daily dosing regimen at start. Persistence with fixed combined ICS-treatment increased with younger age and was decreased in patients having high starting-dose of ICS and prior use of antibiotics. Conclusion New users of both single and fixed combined ICS have alarming low persistence rates with ICS-treatment in the first year of follow-up. Persistence was mainly related to patient factors, such as severity of disease, and to treatment-related factors, such as once-daily dosing frequency. Copyright © 2008 John Wiley & Sons, Ltd.

Trends and determinants of antiresorptive drug use for osteoporosis among elderly women,

PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 10 2005
Sylvie Perreault PhD
Abstract Aim It has been established that women who have had a first osteoporotic fracture are at a significantly greater risk of future fractures. Effective antiresorptive treatments (ART) are available to reduce this risk, yet little information is available on trends in ART drug use among the elderly. The objective is to estimate the rate ratio (RR) of having an ART prescription filled among elderly women and its relation to selected determinants from 1995 through 2001. Method A cohort design was used. Through random sampling, we selected 40% of the women aged 70 years and older listed in the Régie de l'assurance maladie du Québec (RAMQ) health database. The women were grouped into four cohorts (for 1995, 1996, 1998 and 2000). January 1 was established as the index date within each cohort (1995, 1996, 1998 and 2000). The dependent variable was the RR of having at least one prescription of ART drugs filled during the year following the index date among women with and without prior use. ART users were divided in two groups: bone-specific drugs (bisphosphonates, calcitonin, raloxifen) and HRT (hormone replacement therapy). The independent variable was whether or not (control) there had been an osteoporotic-related fracture. The RR was determined for having at least one prescription of bone-specific drugs or of HRT filled during the year following the index date using a Cox regression adjusted for age, chronic disease score (CDS) and prior bone mineral density (BMD) test. Results Crude rates of BMD testing (per 500 person-years) ranged from 20.4 (1995) to 41.1 (2000) in women who had had an osteoporotic-related fracture, and from 4.4 to 15.3 in controls. The crude rate of women (per 100 person-years) who had had an osteoporotic-related fracture and who took at least one bone-specific drug during follow-up ranged from 1.9 in 1995 to 31 in 2000 among those with prior osteoporotic-related fracture, and from 0.5 in 1995 to 11 in 2000 for controls; the corresponding figures for HRT ranged 6.7 in 1995 to 13 in 2000, and from 8.4 in 1995 to 11 in 2000 respectively. BMD test is the only major factor affecting the adjusted RR of having a prescription filled for bone-specific drugs (RR of 10.44; 6.91,15.79 in 1995 and RR of 3.68; 3.30,4.10 in 2000) or HRT (RR of 2.08; 1.64,2.64 in 1995 and RR of 1.44; 1.17,1.77 in 2000), particularly among women who had not had prior use. The fact of having a fracture status does significantly affect the RR of having at least one bone-specific drug prescription filled only among women without prior use (RR of 1.71; 1.26,2.33 in 1996 and RR of 1.77; 1.44,2.19 in 2000). The fact of being younger did not affect the RR of having at least one prescription of bone-specific drugs filled, but being younger increased the RR of filling a prescription of HRT. Conclusions Significant change was seen over time in the number of BMD tests ordered and ART use. Effective osteoporosis interventions are not optimal in the treatment of elderly women in a Canadian health-care system who have had an osteoporotic fracture, given that approximately 25% of women who had had an osteoporotic-related fracture were users of ART.

Severe contact dermatitis as a result of an antiseptic bath oil

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 1 2004
Emma Storer
SUMMARY Siblings aged 7 and 5 years developed extensive truncal and flexural inflammation and desquamation unresponsive to standard eczema therapy. After delays in diagnosis, subsequent history revealed prior use of an antiseptic bath oil in a much stronger concentration than recommended. The case illustrates the severe irritant contact dermatitis that can arise following inadequate dilution of antiseptic bath oils, presumably as a result of skin contact with benzalkonium chloride and triclosan. Features that may direct attention to such irritant dermatitis are flexural predominance with superficial desquamation and rapid improvement after avoidance of exposure to the antiseptic solution.

Access and utilization of a new low-vision rehabilitation service

CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 6 2008
Patricia M O'Connor PhD
Abstract Background:, A new low-vision service linking a public hospital and a non-governmental organization was trialled in Melbourne, Australia. The factors associated with service use were investigated. Methods:, A survey was conducted with patients who used the service, those who accepted referrals but failed to attend and those who refused a referral. Hospital and non-governmental organization representatives were also interviewed. Results:, Ninety-eight eligible vision impaired people who were referred to the new service were recruited. Less than half (49%) followed through with their referral and attended the service. Proximity and convenience were listed as the main facilitators to service use while issues relating to transport, needing an accompanying person, lack of information about the service and poor health were the main barriers. More than a third of the non-compliant and referral refusers spoke a language other than English. Sixty-three per cent of all participants had not previously used low-vision services. Of the two main eye conditions, 81% of referred age-related macular degeneration participants (n = 26) attended the service, but only 32% of those with diabetic retinopathy (n = 31) did so. Conclusion:, As more than 60% of participants in each of the three groups had no prior use of low-vision services, clearly current models of care are not reaching many who could benefit from such services. This suggests that higher rates of referral are warranted. However, given that substantially more were referred than attended, referral alone is obviously not the answer. Access and attitudinal barriers also need to be addressed. [source]


Antecedent use of fluoroquinolones is associated with resistance to moxifloxacin in Clostridium difficile

CLINICAL MICROBIOLOGY AND INFECTION, Issue 6 2003
G. Ackermann
Objective Moxifloxacin is characterized by high activity against Gram-positive cocci and some Gram-positive and -negative anaerobes, including Clostridium difficile. This study investigates the role of prior quinolone use in relation to patterns of susceptibility of C. difficile to moxifloxacin. Methods Sixty-three clinical isolates of C. difficile were investigated for toxigenicity, susceptibility to moxifloxacin, and mutations in the DNA gyrase gene. The medical histories for 50 of these patients were available and used to identify previous fluoroquinolone use. Results Thirty-three (52.4%) strains showed resistance to moxifloxacin (MICs ,,16 mg/L). All moxifloxacin-resistant strains harbored a mutation at amino acid codon Ser-83 of gyrA. Forty-five isolates (71.4%) were toxigenic; all moxifloxacin-resistant strains were in this group. Resistance to moxifloxacin was associated with prior use of fluoroquinolones (P -value 0.009, chi-square). Conclusions Although the use of moxifloxacin to treat C. difficile -associated diarrhea is not likely to be common, these data show a relationship between antecedent fluoroquinolone use and resistance to moxifloxacin in C. difficile isolates, and raise questions regarding selection pressure for resistance placed on colonizing bacteria exposed to fluoroquinolones. Mutations in gyrA are involved in moxifloxacin resistance. [source]
