Etiology and prognosis of pregnancy-related pelvic girdle pain; design of a longitudinal study

Abstract: Absence of knowledge of pregnancy-related pelvic girdle pain (PPGP) has prompted the start of a large cohort study in the Netherlands. The objective of this study was to investigate the prevalence and incidence of PPGP, to identify risk factors involved in the onset and to determine the prognosis of pregnancy-related pelvic girdle pain. 7,526 pregnant women of the southeast of the Netherlands participated in a prospective cohort study. During a 2-year period, they were recruited by midwives and gynecologists at 14 weeks of pregnancy. Participants completed a questionnaire at baseline, at 30 weeks of pregnancy, at 2 weeks after delivery, at 6 months after delivery and at 1 year after delivery. The study uses extensive questionnaires with questions ranging from physical complaints, limitations in activities, restriction in participation, work situation, demographics, lifestyle, pregnancy-related factors and psychosocial factors. This large-scale prospective cohort study will provide reliable insights in incidence, prevalence and factors related to etiology and prognosis of pregnancy-related pelvic girdle pain.

A method for research programming in the field of evidence-based medicine.

Abstract: Objective: This paper presents the method we used in programming research on the efficacy of therapeutic interventions for nine chronic benign pain disorders. Methods: We started with an inventory to identify commonly applied interventions. For these interventions we searched the literature to identify gaps in evidence. First, we searched for recent reviews, of which we assessed the methodologic quality. If only reviews of poor or moderate quality were found, a new systematic review was recommended. When we found no recent reviews, we searched for randomized controlled trials (RCTs). If there was insufficient or inconsistent evidence, the performance of a new RCT was advised. This structured procedure resulted in a list with topics for which new systematic reviews were recommended and topics for which new RCTs were needed. These lists were the starting points for priority setting by four Centers for Pain Management and Research. All members of the centers were asked to state the priority of each topic. The resulting hierarchy of topics for their own center was discussed in a meeting in each center, giving participants the opportunity to elucidate their views and considerations. Results: The final result was a robust priority list for the need of research (systematic reviews and RCTs) on chronic benign pain syndromes. Discussion: The strength and weaknesses of this approach are discussed. This method of priority setting is by no means restricted to treatments for chronic pain; it is also a useful approach for programming research to enable evidence-based medicine in other fields of interest.

Challenges in demonstrating the effectiveness of multidisciplinary treatment on quality of life, participation and health care utilisation in patients with fibromyalgia: a randomised controlled trial

Abstract: This study aimed to examine the effectiveness of a multidisciplinary intervention with aftercare (MD) compared to aerobic exercise (AE) and usual care (UC) in recently diagnosed patients with fibromyalgia (FM). In a Zelen-like design, eligible patients from the outpatient rheumatology clinics of three medical centres in the South of the Netherlands were consecutively recruited and pre-randomised to MD (n = 108), AE (n = 47) or UC (n = 48). MD consisted of a 12-week course of sociotherapy, physiotherapy, psychotherapy and creative arts therapy (three half days per week), followed by five aftercare meetings in 9 months. AE was given twice a week in a 12-week course. UC varied but incorporated at least education and lifestyle advice. Primary outcomes were health-related quality of life (HR-Qol), participation and health care utilisation. Secondary outcome was the Fibromyalgia Impact Questionnaire (FIQ). Total follow-up duration of the study was 21–24 months. As willingness to participate in AE was limited, this group has been analysed but interpretation of the data is considered arguable. Within the MD group, a statistically significantly improved HR-Qol and a statistically significant reduction in number of hours sick leave, number of contacts with general practitioners and number of contacts with medical specialists was found. Moreover, statistically significant improvements were found on the FIQ, which increased after the intervention. However, no statistically significant between-group differences were found at the endpoint of the study. MD seemed to yield positive effects, but firm conclusions with regard to effectiveness cannot be formulated due to small between-group differences and limitations of the study.

Substitution of hospital care with primary care: defining the conditions of Primary Care Plus

Abstract: Objective: To analyse barriers and facilitators in substituting hospital care with primary care to define preconditions for successful implementation Methods: A descriptive feasibility study was performed to collect information on the feasibility of substituting hospital care with primary care General practitioners were able to refer patients, about whom they had doubts regarding diagnosis, treatment and/or the need to refer to hospital care, to medical specialists who performed low-complex consultations at general practitioner practices Qualitative data were collected through interviews with general practitioners and medical specialists, focus groups and notes from meetings in the Netherlands between April 2013 and January 2014 Data were analysed using a conventional content analysis which resulted in categorised barriers, facilitators and policy adjustments, after which preconditions were formulated Results: The most important preconditions were make arrangements on governmental level, arrange a collective integrated IT-system, determine the appropriate profile for medical specialists, design a referral protocol for eligible patients, arrange deliberation possibilities for general practitioners and medical specialists and formulate a diagnostic protocol Conclusions: The barriers, facilitators and formulated preconditions provided relevant input to change the design of substituting hospital care with primary care

The feasibility and efficacy of a multidisciplinary intervention with aftercare meetings for fibromyalgia.

Abstract: The objective of this study is to examine the feasibility and long-term results of a 12-week multidisciplinary part-time daycare intervention with five aftercare meetings in fibromyalgia (FM) patients. One hundred and five patients diagnosed with FM started with a multidisciplinary intervention and were assessed for feasibility, functional status (Fibromyalgia Impact Questionnaire [FIQ]), and quality of life (EuroQol-5D [EQ-5D]) until 9 months after completion. The program consisted of sociotherapy, physiotherapy, psychotherapy, and creative arts therapy. Drop-out rate was 4.8%. The attendance rate of 100 patients who completed the 12-week program and five aftercare meetings was high (97.4%), just like patient and therapist satisfaction (8.2 on a 10 points scale). After the 12-week program, statistically significant improvement was seen in both FIQ and EQ-5D. This improvement was maintained after 9 months of follow-up. On average, moderate improvements were observed. Our 12-week multidisciplinary part-time daycare intervention with five aftercare meetings for FM patients is feasible and it is indicated that it can lead to sustained improvement in functional status and quality of life.

Factors influencing the composition of the intestinal microbiota in early infancy

Abstract: OBJECTIVE.The aim of this study was to examine the contribution of a broad range of external influences to the gut microbiotic composition in early infancy. METHODS.Fecal samples from 1032 infants at 1 month of age, who were recruited from the KOALA Birth Cohort Study in the Netherlands, were subjected to quantitative real-time polymerase chain reaction assays for the enumeration of bifidobacteria, Escherichia coli, Clostridium difficile, Bacteroides fragilis group, lactobacilli, and total bacterial counts. Information on potential determinants of the gut microbiotic composition was collected with repeated questionnaires. The associations between these factors and the selected gut bacteria were analyzed with univariate and multivariate analyses. RESULTS.Infants born through cesarean section had lower numbers of bifidobacteria and Bacteroides, whereas they were more often colonized with C difficile, compared with vaginally born infants. Exclusively formula-fed infants were more often colonized with E coli, C difficile, Bacteroides, and lactobacilli, compared with breastfed infants. Hospitalization and prematurity were associated with higher prevalence and counts of C difficile. Antibiotic use by the infant was associated with decreased numbers of bifidobacteria and Bacteroides. Infants with older siblings had slightly higher numbers of bifidobacteria, compared with infants without siblings. CONCLUSIONS.The most important determinants of the gut microbiotic composition in infants were the mode of delivery, type of infant feeding, gestational age, infant hospitalization, and antibiotic use by the infant. Term infants who were born vaginally at home and were breastfed exclusively seemed to have the most “beneficial” gut microbiota (highest numbers of bifidobacteria and lowest numbers of C difficile and E coli).

Psychological therapies for the management of chronic pain (excluding headache) in adults

Abstract: Background Psychological treatments are designed to treat pain, distress and disability, and are in common practice. This review updates and extends the 2009 version of this systematic review. Objectives To evaluate the effectiveness of psychological therapies for chronic pain (excluding headache) in adults, compared with treatment as usual, waiting list control, or placebo control, for pain, disability, mood and catastrophic thinking. Search methods We identified randomised controlled trials (RCTs) of psychological therapy by searching CENTRAL, MEDLINE, EMBASE and Psychlit from the beginning of each abstracting service until September 2011. We identified additional studies from the reference lists of retrieved papers and from discussion with investigators. Selection criteria Full publications of RCTs of psychological treatments compared with an active treatment, waiting list or treatment as usual. We excluded studies if the pain was primarily headache, or was associated with a malignant disease. We also excluded studies if the number of patients in any treatment arm was less than 20. Data collection and analysis Forty-two studies met our criteria and 35 (4788 participants) provided data. Two authors rated all studies. We coded risk of bias as well as both the quality of the treatments and the methods using a scale designed for the purpose. We compared two main classes of treatment (cognitive behavioural therapy(CBT) and behaviour therapy) with two control conditions (treatment as usual; active control) at two assessment points (immediately following treatment and six months or more following treatment), giving eight comparisons. For each comparison, we assessed treatment effectiveness on four outcomes: pain, disability, mood and catastrophic thinking, giving a total of 32 possible analyses, of which there were data for 25. Main results Overall there is an absence of evidence for behaviour therapy, except a small improvement in mood immediately following treatment when compared with an active control. CBT has small positive effects on disability and catastrophising, but not on pain or mood, when compared with active controls. CBT has small to moderate effects on pain, disability, mood and catastrophising immediately post-treatment when compared with treatment as usual/waiting list, but all except a small effect on mood had disappeared at follow-up. At present there are insufficient data on the quality or content of treatment to investigate their influence on outcome. The quality of the trial design has improved over time but the quality of treatments has not. Authors' conclusions Benefits of CBT emerged almost entirely from comparisons with treatment as usual/waiting list, not with active controls. CBT but not behaviour therapy has weak effects in improving pain, but only immediately post-treatment and when compared with treatment as usual/waiting list. CBT but not behaviour therapy has small effects on disability associated with chronic pain, with some maintenance at six months. CBT is effective in altering mood and catastrophising outcomes, when compared with treatment as usual/waiting list, with some evidence that this is maintained at six months. Behaviour therapy has no effects on mood, but showed an effect on catastrophising immediately post-treatment. CBT is a useful approach to the management of chronic pain. There is no need for more general RCTs reporting group means: rather, different types of studies and analyses are needed to identify which components of CBT work for which type of patient on which outcome/s, and to try to understand why.

Gut microbiota composition and development of atopic manifestations in infancy: the KOALA Birth Cohort Study

Abstract: Background and aims: Perturbations in intestinal microbiota composition due to lifestyle changes may be involved in the development of atopic diseases. We examined gut microbiota composition in early infancy and the subsequent development of atopic manifestations and sensitisation. Methods: The faeces of 957 infants aged 1 month and participating in the KOALA Birth Cohort Study were analysed using quantitative real-time PCR. Information on atopic symptoms (eczema, wheeze) and potential confounders was acquired through repeated questionnaires. Total and specific IgE were measured in venous blood samples collected during home visits when the infant was 2 years old. During these home visits a clinical diagnosis of atopic dermatitis was made according to the UK-Working Party criteria. Results: The presence of Escherichia coli was associated with a higher risk of developing eczema (OR adj = 1.87; 95% CI 1.15 to 3.04), this risk being increased with increasing numbers of E coli (p for trend = 0.016). Infants colonised with Clostridium difficile were at higher risk of developing eczema (OR adj = 1.40; 95% CI 1.02 to 1.91), recurrent wheeze (OR adj = 1.75; 95% CI 1.09 to 2.80) and allergic sensitisation (OR adj = 1.54; 95% CI 1.02 to 2.31). Furthermore, the presence of C difficile was also associated with a higher risk of a diagnosis of atopic dermatitis during the home visit (OR adj = 1.73; 95% CI 1.08 to 2.78). Conclusion: This study demonstrates that differences in gut microbiota composition precede the development of atopy. Since E coli was only associated with eczema and C difficile was associated with all atopic outcomes, the underlying mechanisms explaining these association may be different.
