Evaluation of a holistic treatment and teaching programme for patients with Type 1 diabetes who failed to achieve their therapeutic goals under intensified insulin therapy

DIABETIC MEDICINE, Issue 9 2000
U. Bott
SUMMARY Aims To evaluate a treatment and teaching programme including psychosocial modules for patients with Type 1 diabetes mellitus on intensified insulin therapy who failed to achieve their treatment goals despite participation in standard programmes. Methods The 5-day inpatient programme comprises small groups of 4,6 patients, focusing on individual needs and problems. Beyond the teaching lessons (most topics are deliberately chosen by the patients), the programme provides intensive group discussions and offers individual counselling concerning motivational aspects, psychosocial problems and coping strategies. Of the first consecutive 83 participants, 76 were re-examined after 17.5 ± 5.5 months (range 9,31 months). Results At follow-up, HbA1c was not improved compared to baseline (8.0 ± 1.3% vs. 8.1 ± 1.5%). However, the incidence of severe hypoglycaemia per patient/year (glucose i.v., glucagon injection) was substantially decreased: 0.62 ± 1.5 episodes at baseline compared to 0.16 ± 0.9 at follow-up (P < 0.001). Twenty-six per cent of the patients at baseline, and 4% at re-examination had experienced at least one episode of severe hypoglycaemia during the preceding year (P < 0.001). Sick leave days per patient/year decreased from 17.0 ± 38.5,7.7 ± 13.6 days (P < 0.05). Patients improved their perceptions of self-efficacy, their relationship to doctors and felt less externally controlled (P < 0.001). The majority of patients perceived an improved competence regarding diet (80.6%) and adaptation of insulin dosage (82.4%), an improved knowledge (82.2%), and a renewed motivation for the treatment (84.5%). Treatment success was significantly associated with baseline HbA1c, stability of motivation, frequency of blood glucose self-monitoring, control beliefs and change in subsequent outpatient care. Conclusions The programme improved glycaemic control mainly as a result of a substantial reduction in the incidence of severe hypoglycaemia. Patients with persistent poor glycaemic control may benefit from structured follow-up care focusing on motivational aspects of self-management and psychosocial support. [source]

A longitudinal observational study of a cohort of patients with relapsing,remitting multiple sclerosis treated with glatiramer acetate

EUROPEAN JOURNAL OF NEUROLOGY, Issue 11 2007
M. Debouverie
Immunomodulatory treatments for relapsing,remitting multiple sclerosis (RRMS) are not efficacious or tolerated in all patients. It is important to evaluate alternative classes of treatment in patients failing first-line therapy. The objective of this prospective observational study was to evaluate the efficacy and safety of glatiramer acetate in patients, to whom , -interferons could not be administered. The study included patients with RRMS who were intolerant to or had contraindications to , -interferon. After initiation of glatiramer acetate treatment, follow-up visits were made every 3 months, when data on neurologist-ascertained relapses and disability [Expanded Disability Status Scale (EDSS) score] were collected. Tolerability was evaluated by spontaneous adverse event reporting. Overall, 205 patients were studied and 113 (55.1%) treated for at least 4 years. The proportion of patients presenting over three relapses per year decreased from 51.2% to 8.4% in the 2 years following treatment initiation. Over 5 years of treatment, mean annualized relapse rates and mean EDSS scores remained stable (0.4,0.6 relapses/year and 3.6 ± 1.8,3.3 ± 2.1 respectively). Adverse events were reported by 179 patients, leading to discontinuation of treatment in 10 patients. Patients with RRMS to whom , -interferons cannot be prescribed can benefit from treatment with glatiramer acetate. [source]

Salvage laryngectomy and pharyngocutaneous fistulae after primary radiotherapy for head and neck cancer: A national survey from DAHANCA

Cai Grau MD, DMSc
Objective. In 1998, the Danish Society for Head and Neck Oncology decided to conduct a nationwide survey at the five head and neck oncology centers with the aim of evaluating the surgical outcome of salvage laryngectomy after radiotherapy with special emphasis on identifying factors that could contribute to the development of pharyngocutaneous fistulae. Patients. A total of 472 consecutive patients undergoing postirradiation salvage laryngectomy in the period July 1, 1987,June 30, 1997 were recorded at the five head and neck oncology centers in Denmark. Age ranged from 36 to 84 years, median 63 years, 405 men and 67 women. Primary tumor site was glottic larynx (n = 242), supraglottic larynx (n = 149), other larynx (n = 45), pharynx (n = 27), and other (n = 9). All patients had received prior radiotherapy. Results. Median time between radiotherapy and laryngectomy was 10 months (range, 1,348 months). A total of 89 fistulae lasting at least 2 weeks were observed, corresponding to an overall average fistulae risk of 19%. The number of performed laryngectomies per year decreased linearly (from 58 to 37), whereas the annual number of fistulae increased slightly (from 7 to 11), which meant that the corresponding estimated fistulae risk increased significantly from 12% in 1987 to 30% in 1997. Other significant risk factors for fistulae in univariate analysis included younger patient age, primary advanced T and N stage, nonglottic primary site, resection of hyoid bone, high total radiation dose, and large radiation fields. Multiple logistic regression analysis of these parameters suggested that nonglottic tumor site, late laryngectomy period (1987,1992 vs 1993,1997), and advanced initial T stage were independent prognostic factors for fistulae risk. Surgical parameters like resection of thyroid/tongue base/trachea or radiotherapy parameters like overall treatment time or fractions per week did not influence fistulae risk. Conclusions. The risk of fistulae is especially high in patients initially treated with radiotherapy for nonglottic advanced stage tumors. A significant decrease in the number of performed salvage laryngectomies over the 10 years was seen. Over the same time period, the annual number of fistulae remained almost constant. The resulting more than doubling of fistulae rate could thus in part be explained by less surgical routine. © 2003 Wiley Periodicals, Inc. Head Neck 25: 711,716, 2003 [source]

Changes in the initiation of heroin use after a reduction in heroin supply

DRUG AND ALCOHOL REVIEW, Issue 4 2006
CAROLYN DAY
Abstract Increasing heroin use in Australia over the past 30 years has been associated with a decline in the age of initiation to heroin use. The 2001 Australian heroin shortage was used to assess the effects of a reduction in heroin supply on age of initiation into heroin injecting. Data collected from regular injecting drug users (IDU) over the period 1996,2004 as part of the Australian Illicit Drug Reporting System were examined for changes in self-reported age of first heroin use after the onset of the heroin shortage. Estimates were also made of the number of young people who may not have commenced injecting heroin during the heroin shortage. The proportion of IDU interviewed in the IDRS who were aged ,24 years decreased from 46% in 1996 to 12% in 2004, with the most marked drop in 2001, the year in which there was an abrupt and marked reduction in heroin availability. Of those who reported first injecting between 1993 and 2000, similar proportions reported heroin and amphetamine as the first drug injected. After 2000, methamphetamine was the drug most often reported as being the first injected. Estimates suggested that between 2745 and 10 560 young people may not have begun to inject heroin in 2001 as a result of reduced heroin supply. If around one in four of these young users had progressed to regular or dependent heroin use, then there may have been a reduction of between 700 and 2500 dependent heroin users. There was an increase in amphetamine injecting but it is unclear to what extent any reduction in heroin injecting has been offset by increased amphetamine injecting. Reduced heroin availability probably resulted in a reduction in the number of new heroin injectors in Australia. Efforts need to be made to reduce the chances that young people who have initiated methamphetamine injecting do not move to heroin injecting when the heroin supply returns. [source]

Abstract This study was conducted to describe level of conflict, conflict management styles, level of job satisfaction, and intent to stay, and to ascertain relationships among conflict, conflict management styles, level of job satisfaction, intent to stay, and turnover of professional nurses in Thailand. The sample was 354 professional nurses employed in four regional hospitals in Thailand. The findings showed that the overall level of conflict was at a moderate level. The majority of subjects used accommodation most frequently to manage conflict. Subjects were dissatisfied with pay but were neither satisfied nor dissatisfied with work, supervision, opportunities for promotion, co-workers and the job in general facets of job satisfaction. Most subjects had a high intent to stay in their present jobs for 1 year (97.1%) but intent to stay for the next 5 years decreased (78.5%). The result showed some relationships among these variables, but no relationship between intent to stay and turnover of professional nurses. [source]

Long-term surveillance of invasive group A streptococcal disease in The Netherlands, 1994,2003

CLINICAL MICROBIOLOGY AND INFECTION, Issue 3 2005

Abstract A nationwide laboratory-based surveillance study of invasive group A streptococcal (GAS) infections was conducted in The Netherlands from May 1994 until December 2003 (average population during this period was 15 729 704). Microbiologically invasive isolates were obtained from 1504 patients, with most (70%) isolates cultured from blood. There was a clear seasonal pattern in invasive streptococcal infections, with an estimated annual incidence that peaked in 1996 (4.0 cases/100 000 individuals/year) and was at its lowest in 1999 (2.0 cases/100 000 individuals/year). Twenty-eight different M-types were identified, of which the most frequent were M1 (339/1504, 23%), M3 (187/1504, 12%), M89 (174/1504, 12%), M28 (164/1504, 11%), M12 (109/1504, 7%) and M6 (55/1504, 4%). There was a high degree of variation in the relative annual contributions of the predominant M-types, but variations in M1 and M3 combined correlated with overall changes in the annual incidence. The contribution of the patient group aged ,,56 years to all cases of invasive GAS disease increased during the study period, whereas that of the group aged 0,20 years decreased. A peak in the incidence of invasive GAS disease among the patient group aged 30,34 years did not vary during the study period, indicating that the high incidence of invasive GAS disease in this age group was age-specific rather than cohort-related.
