Increasing levels of burnout in Swedish midwives - A ten-year comparative study

PROBLEM

Midwives' levels of burnout seem to be increasing worldwide.

BACKGROUND

Previous research show a high prevalence of burnout in midwives.

AIM

To compare levels of burnout in two national Swedish samples of midwives completing a similar survey.

METHODS

A comparative study of two cross-sectional national surveys directed at midwives in 2012 and 2022. To measure burnout in midwives, the Copenhagen Burnout Inventory with 19 items was used.

FINDINGS

The sample consisted of 2209 midwives: 466 from 2012 and 1743 from 2022. Personal burnout showed an increase from 39.5 % to 53.6 % over the years; work burnout increased from 15.5 % to 49.2 % and client burnout increased from 15 % to 20.9 %. Personal burnout was associated with working shift. Work burnout was associated with length of work experience and working rotating shifts; and client burnout was associated with shorter work experience.

DISCUSSION

The highest increase in burnout was found in the work domain in 2022 compared to 2012. Notable in the present study is the increase in client burnout, which could be a sign of midwives becoming less caring and more cynical.

CONCLUSION

This study showed that self-reported levels of burnout among Swedish midwives increased over the ten-year period studied. The largest increase was found in the subscale work burnout. Midwives with shorter work experience and those with shift work were the most vulnerable to burnout. Improved organisation of midwifery services needs to be designed to ensure healthy working conditions for midwives.

Swedish midwives' attitudes towards continuity models-a cross-sectional survey

BACKGROUND

Midwifery continuity models are growing worldwide, but few such alternatives are available in Sweden. There is sparse knowledge about Swedish midwives' attitudes about midwifery continuity models.

AIM

The aim of this study was to explore Swedish midwives' attitudes toward continuity models. An additional aim was to evaluate the psychometric properties of a previously developed instrument measuring attitudes to continuity models.

METHODS

A cross-sectional survey of a national sample of 2537 midwives in Sweden. The participants completed a questionnaire online. A Principal component Analysis was performed to identify components in the instrument.

RESULTS

A fairly similar proportion of midwives worked in antenatal care (30.7%), intrapartum care (30.7%) and in other areas (31.1%). Many midwives (59%) agreed that continuity models should be available to women, but were not certain about if such models should be offered to all women or low risk women only. Two domains of the attitude scale were identified; Relationship-based Midwifery Continuity Models, and Practical and Organisational Aspects of Midwifery Continuity Models. Age, having children, marital status, length of work experience and place of work were associated with high agreement non the two components.

CONCLUSION

Many midwives in general held positive attitudes about continuity models. The relationship aspects were highly valued but midwives were also hesitant about the practical and organisational aspect of continuity models. Unbiased information to midwives about the pros and cons with continuity models should be offered, in order to limit misunderstandings about the model.

Previous negative experiences of healthcare reported by Swedish pregnant women with fear of birth - A mixed method study

BACKGROUND

Negative encounters in healthcare might affect women's health. During their reproductive life span, women are exposed to various health examinations, and have reported disrespectful care and obstetric violence. Such experiences might be a basis for fear of birth.

AIM

to explore and describe the prevalence, associated factors and experiences of previous negative healthcare encounters in women with fear of birth.

METHODS

A cross-sectional mixed-method study of 335 pregnant women with fear of birth. Data were collected by a questionnaire in mid-pregnancy, which included socio-demographic and obstetric background data as well as a question about the occurrence of previous negative experiences in healthcare.

RESULT

A previous negative experience of healthcare was found in 189 women (56.6%). The analysis of the women's comments regarding what caused their negative experiences generated three themes: disrespectful treatment and no one listened; painful, inadequate, or improper care; and impact of other people's stories.

CONCLUSION

This study showed that previous negative experiences in healthcare were common in women with fear of birth and the content of the encounters could be summarised as disrespectful care and obstetric violence. Women's previous encounters in healthcare might be an underlying reason for fear of birth and should be investigated. It is, therefore, of utmost importance to listen to women and their narratives in order to establish a trustful relationship and promote evidence-based, women-centred, respectful care, which is urgently needed.

'A perfect fit' - Swedish midwives' interest in continuity models of midwifery care

BACKGROUND

Midwifery continuity models of care are highly recommended yet rare in Sweden, although approximately 50% of pregnant women request them. Before introducing and scaling up continuity models in Sweden, midwives' attitudes about working in continuity models must be investigated.

OBJECTIVE

to investigate Swedish midwives' interests in working in midwifery continuity models of care and factors influencing the midwifery workforce's readiness for such models.

METHODS

A cross-sectional online survey was utilised and information collected from a national sample of midwives recruited from two unions regarding background and work-related variables. Crude and adjusted odds ratios and logistic regression analysis were used in the analysis.

RESULTS

A total of 2084 midwives responded and 56.1% reported an interest. The logistic regression model showed that respondents' ages 24-35 years (OR 1.73) or 35-45 years (OR 1.46); years of work experience 0-3 years (OR 5.81) and 3-10 years (OR 2.04); rotating between wards or between tasks (OR 2.02) and working temporary (OR 1.99) were related to interest in continuity models. In addition, working daytime only (OR 1.59) or on a two-shift schedule (OR 1.93) was associated with such interest.

CONCLUSION

A sufficient number of midwives in Sweden appear to be interested in working in continuity models of midwifery care to align with women's interest in having a known midwife throughout pregnancy, birth and postpartum period. Developing strategies and continuity models that will address the preferences of women in various areas of Sweden is important for offering evidence-based maternity services.

Fulfilment of expectations on birth and the postpartum period - A Swedish cohort study

BACKGROUND

The fulfilment of birth expectations is important to women and strongly related to birth satisfaction.

OBJECTIVE

The aim of this study was to investigate women's expectations and experiences of birth and the postnatal period and associated factors. An additional aim was to explore if women's expectations were fulfilled.

METHODS

A longitudinal cohort study of 280 women where 226 were followed up two months after birth. Data were collected using questionnaires. Odds ratios with a 95% confidence interval were calculated between the explanatory background variables and expectations/experiences.

RESULTS

The majority (79%) rated continuity as important, but few (32%) actually had a known midwife assisting during birth. Positive birth expectations were found in 37% and a positive birth experience in 66%. Many women (56%) preferred a short postnatal stay, and 63% went home within 24 h. Thirty-six percent preferred postnatal home visits, but only eight women (3.5%) received this. Breastfeeding expectations were high with 86% rating it as important but after birth 63% reported exclusively breastfeeding. Only a few background factors were associated with women's expectations and experiences. Most likely to be fulfilled were women's expectations for a vaginal birth (83%), a positive birth experience (71%) and short length of postnatal stay (67%). Postnatal home visits (96%) and continuity of care (73%) were not fulfilled.

CONCLUSIONS

Pregnant women's expectations about continuity are fulfilled only to a minor degree. The fulfilment of postnatal expectations varied and the preference for a short postnatal stay was fulfilled whereas home visits were not.

Anxiety and depressive symptoms in women with fear of birth: A longitudinal cohort study

INTRODUCTION

Anxiety and depression during pregnancy could imply difficulties in the attachment to the unborn baby. The objective of this study was to investigate the prevalence and change in anxiety and depressive symptoms in pregnant women with fear of birth. Another aim was to explore associations between symptoms of anxiety and depression on prenatal attachment.

METHODS

This is a longitudinal cohort study of 77 pregnant women with fear of birth in three hospitals in Sweden. Data were collected by three questionnaires in mid and late pregnancy and two months after birth.

RESULTS

Anxiety symptoms were more often reported than depressive symptoms, significantly decreasing over time in both conditions. Anxiety symptoms were associated with low education level, negative feelings towards the upcoming birth, and levels of fear of birth. Depressive symptoms were associated with levels of fear of birth. One in five women presented with fear of birth, anxiety, and depressive symptoms, suggesting that co-morbidity was quite common in this sample. Depressive symptoms and co-morbidity were negatively associated with prenatal attachment.

CONCLUSIONS

This study shows that symptoms of anxiety and depression in women with fear of birth vary over time and that co-morbidity is quite common. Lack of emotional well-being was related to prenatal attachment. Healthcare professionals must identify and support women with anxiety and depressive symptoms and fear of birth so that difficulties in the relationship between the mother and the newborn baby might be reduced.

Partners' expectations and experiences of the project 'Midwife All the Way': A qualitative study

INTRODUCTION

Continuity models of midwifery care are significant factors in facilitating a positive childbirth experience for birthing women. A knowledge gap exists regarding partners' experiences of continuity of midwifery care during pregnancy, birth, and after birth, although it is essential to understand the experiences of both parents in relation to continuity of care. Thus, the aim of this study was to highlight partners' expectations and experiences of having participated in a continuity of midwifery care project.

METHODS

A qualitative interview study using thematic analysis was carried out. Thirty-six partners in a rural area in northern Sweden were recruited after the closure of the local labor ward. Interviews were conducted in October 2019 and in May 2020.

RESULTS

An overarching theme: 'A partner-midwife relationship facilitated a sense of security'; and two themes 'The concept of availability' and 'The midwife's competence and professionalism' reflect partners' expectations and experiences after participating in a continuity of midwifery care project.

CONCLUSIONS

Professionalism was most highly valued, but establishing a relationship with a known midwife facilitated a sense of security. When birthing women feel safe with the known midwife, the partners also feel safe. Having to travel a long-distance to a labor ward caused concern for the partners. This highlights the importance of an organization that supports families to gain access to continuity models of midwifery care and to have a possibility to give birth closer to their residence. The results of this qualitative study further strengthen the growing evidence of the positive effects of continuity models of midwifery care.

Quality of intrapartum care assessed by women participating in a midwifery model of continuity of care

INTRODUCTION

Continuity models are rare in Sweden. The aim was to compare the intrapartum care experiences between women who had or not a known midwife attending their birth.

METHODS

A cohort study was conducted in a rural area with long distance to a labor ward in Sweden. From August 2017 to June 2019, a continuity model with a known midwife was offered between 7 a.m. and 11 p.m. daily. Questions about intrapartum care were assessed in two aspects; the perceived reality and the subjective importance.

RESULTS

A total of 226 women recruited in early pregnancy were followed up two months after giving birth. Women who had a known midwife providing labor care reported higher overall satisfaction and were more likely to value the subjective importance and the perceived reality significantly higher than women who received intrapartum care without a known midwife assisting. When analyzing the medical aspects of intrapartum care, the most important factors for not being satisfied were deficiencies in the partner’s involvement and insufficient pain relief. For the emotional aspects, deficiencies in participation in decision making was the most important aspect.

CONCLUSIONS

Having a known midwife assisting at birth reduced discrepancies between women’s subjective importance and perceived reality of intrapartum care, especially regarding support and the involvement of the partner. A known midwife generated higher overall satisfaction with the medical and emotional aspects of intrapartum care. To improve satisfaction and the quality of intrapartum care, continuity midwifery models of care should be implemented.

Demanding and rewarding: Midwives experiences of starting a continuity of care project in rural Sweden

INTRODUCTION

The closure of a local labor ward enhanced the possibility to initiate a continuity of midwifery care model project. Continuity models of midwifery care are a cornerstone in midwifery and women-centered care, mainly accessible in metropolitan areas. Australian studies have found continuity of midwifery care to work well in rural areas. The aim of this study is to describe midwives' experiences of developing and working in a continuity of midwifery model of care in a rural setting in Sweden.

METHODS

We used a qualitative longitudinal interview with a participatory action research approach. The project was subjected to changes over time to allow the midwives to provide the best care options and to develop a model suitable for a rural area in northern Sweden.

RESULTS

The overarching theme, 'Developing a continuity model of midwifery care - demanding and rewarding with new insights', was based on three themes: 1) A challenging but evolving start, 2) Varying views within the midwifery group, and 3) Visions for the future. It was revealed that the midwives had to handle the grief process of the closure of the labor ward alongside their enthusiasm of being part of a continuity of midwifery care model project.

CONCLUSIONS

The establishment of the model in light of the labor ward closure was associated with conflict within the community and this had implications for the midwives. Midwives who are attracted to work in continuity models need to understand and incorporate the prerequisites of such models. In addition, long commuting to a labor ward requires enough midwives to maintain safety and security for the women at all times.

Women's worries during pregnancy; a cross-sectional survey using the Cambridge Worry Scale in a rural area with long distance to hospital

BACKGROUND

Worries are common during pregnancy, but there is sparse knowledge of worries when the distance to hospital is long.

AIM

To assess the extent and content of worries during pregnancy. Another aim was to evaluate the psychometric properties of the Swedish version of the Cambridge Worry Scale.

METHOD

Cross-sectional study of 280 women recruited to a continuity project and completed a questionnaire in mid pregnancy.

RESULT

Women were most worried about something being wrong with the baby, giving birth and the risk of miscarriage. Women also reported worries about giving birth on the road or in the car. Two domains of the Cambridge Worry scale were identified; Socio-medical and health aspects and Socio-economic and relationship aspects. Women with high fear and depressive symptoms were most at risk for major worries.

CONCLUSION

Worries during pregnancy were mainly related to issues about pregnancy and birth, and specifically, to long distance to the labour ward. Women with depressive symptoms and fear of birth showed the highest levels of worries. When a woman expresses worries in connection to labour and birth, caregivers must be sensitive to the presence of underling fears or depressive symptoms and act to refer women to treatment or support.

Childbirth experience in women participating in a continuity of midwifery care project

BACKGROUND

Continuity models of care are rare in Sweden, despite the evidence of their benefit to women and babies. Previous studies have shown certain factors are associated with a positive birth experience, including continuity of midwifery care.

AIM

The aim was to investigate women's childbirth experiences in relation to background data, birth outcome and continuity with a known midwife, in a rural area of Sweden.

METHODS

An experimental cohort study. Participating women were offered continuity of midwifery care in pregnancy and birth, during selected time periods. Data were collected in mid-pregnancy and two months after birth. The Childbirth Experience Questionnaire was used to determine women's birth experiences.

RESULT

A total of 226 women responded to the follow-up questionnaire. Not living with a partner, fear of giving birth, and a birth preference other than vaginal were associated with a less positive birth experience. Having had a vaginal birth with no epidural, no augmentation and no birth complication all yield a better birth experience. Women who had had a known midwife were more likely to have had a positive birth experience overall, predominantly in the domain Professional support.

CONCLUSIONS

The results of this study showed that women who received care from a known midwife in labour were more likely to have a positive birth experience. The results also pointed out the benefits of a less medicalized birth as important for a good birth experience, and that some women may need extra support to avoid a less positive birth experience.

Pain intensity and pressure pain thresholds after a light dynamic physical load in patients with chronic neck-shoulder pain

Background

To investigate the development of pain intensity and pressure pain thresholds during and 24 h after a light dynamic physical load among patients with chronic neck-shoulder pain.

Methods

Twenty-six patients with chronic neck-shoulder pain and 12 healthy controls were included. The participants arm-cycled on an ergometer. Effort was rated with the Borg Rating of Perceived Exertion scale (RPE), and pain intensity with an numeric rating scale (NRS). Pressure pain thresholds were measured by an algometer. Participants started a pain diary 1 week before the physical exercise and continued until 1 week after. Pain intensity was assessed before, during and the following two evenings after arm-cycling. Pressure pain thresholds were assessed before, 15 min after, 105 min after and 24 h after.

Results

The chronic pain group showed increased pain intensity during, and the following two evenings after the arm cycling, and decreased pain thresholds immediately after the arm cycling involving painful regions. In the patient group there were no impact on pain thresholds in the neck the following day.

Conclusions

Patients with chronic neck-shoulder pain reported increased pain intensity during and in the evenings after a light dynamic load involving painful regions. In addition, they showed decreased pain thresholds close to the exercise, indicating mechanical hyperalgesia.

Birth outcome in a caseload study conducted in a rural area of Sweden-a register based study

BACKGROUND

Continuity models of midwifery care are rare in Sweden, despite its well-known positive effects. The aim was to describe pregnancy and birth outcome in women participating in a continuity of care project in a rural area of Sweden.

METHOD

A register-based study of 266 women recruited to the project and a control group of 125 women from the same catchment area. Midwives provided antenatal care and were on-call 7 a.m. to 11 p.m. for birth. Data were collected from the antenatal and birth records. Crude and adjusted odds ratios with 95% confidence intervals were calculated between women in the project and the control group.

RESULTS

There were more primiparous women and highly educated women recruited to the project, and fewer foreign-born and single women, compared to the control group. Women in the project met more midwives and were less likely to have a pregnancy complication. During intrapartum care, women recruited to the project were less likely to need labour augmentation and less likely to have an instrumental vaginal birth and elective caesarean section. They had fewer second degree perineal tears and were more likely to fully breastfeed at discharge. No differences were found in neonatal outcome. The continuity of a known midwife at birth was quite low.

CONCLUSION

This study shows that women self-recruited to a continuity of care project in a rural area of Sweden had a higher rate of normal births. There were few differences if having a known midwife or not. Long distances to hospital and lack of staff affected the level of continuity.

Enzymatic Determination of Lactose and Galactose in Foods: NMKL Collaborative Methods Performance Study

Enzymes are widely used in food chemistry as analytical tools. An enzymatic method for determining lactose and galactose in foods was evaluated in an interlaboratory methods performance study by 12 laboratories in 4 countries. The method is based on enzymatic hydrolysis of lactose and enzymatic oxidation of the hydrolysis products. The exchange of the coenzyme in the second reaction is the basis of quantitation. The method may be used for various types of foods, such as liquid and solid milk products, meat products, cereal products, fats, dressings, sweets, chocolate, and foods for special dietary uses. It is also applicable to lactose-free foods but not to products in which lactose has been partially hydrolyzed enzymatically to glucose and galactose. Six commonly used foodstuffs with lactose concentrations ranging from 0.4 g/100 g to 40 g/100 g and galactose concentrations up to 0.7 g/100 g were analyzed: crisp rye bread, milk chocolate, sausage, cheese, margarine, and baby food containing milk powder. They were distributed to the 12 participants as 12 randomly numbered test samples, representing blind duplicates of the 6 materials. The relative standard deviations for reproducibility (RSDR) were between 2.3-11% for lactose and 6.8-50% for galactose.

Factors influencing decision-making for caesarean section in Sweden - a qualitative study

BACKGROUND

Rising rates of caesarean section (CS) are a concern in many countries, yet Sweden has managed to maintain low CS rates. Exploring the multifactorial and complex reasons behind the rising trend in CS has become an important goal for health professionals. The aim of the study was to explore Swedish obstetricians' and midwives' perceptions of the factors influencing decision-making for CS in nulliparous women in Sweden.

METHODS

A qualitative design was chosen to gain in-depth understanding of the factors influencing the decision-making process for CS. Purposive sampling was used to select the participants. Four audio-recorded focus group interviews (FGIs), using an interview guide with open ended questions, were conducted with eleven midwives and five obstetricians from two selected Swedish maternity hospitals after obtaining written consent from each participant. Data were managed using NVivo© and thematically analysed. Ethical approval was granted by Trinity College Dublin.

RESULTS

The thematic analysis resulted in three main themes; 'Belief in normal birth - a cultural perspective'; 'Clarity and consistency - a system perspective' and 'Obstetrician makes the final decision, but...', and each theme contained a number of subthemes. However, 'Belief in normal birth' emerged as the core central theme, overarching the other two themes.

CONCLUSION

Findings suggest that believing that normal birth offers women and babies the best possible outcome contributes to having and maintaining a low CS rate. Both midwives and obstetricians agreed that having a shared belief (in normal birth), a common goal (of achieving normal birth) and providing mainly midwife-led care within a 'team approach' helped them achieve their goal and keep their CS rate low.

Comparing Internet-Based Cognitive Behavioral Therapy With Standard Care for Women With Fear of Birth: Randomized Controlled Trial

BACKGROUND

Although many pregnant women report fear related to the approaching birth, no consensus exists on how fear of birth should be handled in clinical care.

OBJECTIVE

This randomized controlled trial aimed to compare the efficacy of a guided internet-based self-help program based on cognitive behavioral therapy (guided ICBT) with standard care on the levels of fear of birth in a sample of pregnant women reporting fear of birth.

METHODS

This nonblinded, multicenter randomized controlled trial with a parallel design was conducted at three study centers (hospitals) in Sweden. Recruitment commenced at the ultrasound screening examination during gestational weeks 17-20. The therapist-guided ICBT intervention was inspired by the Unified protocol for transdiagnostic treatment of emotional disorders and consisted of 8 treatment modules and 1 module for postpartum follow-up. The aim was to help participants observe and understand their fear of birth and find new ways of coping with difficult thoughts and emotions. Standard care was offered in the three different study regions. The primary outcome was self-assessed levels of fear of birth, measured using the Fear of Birth Scale.

RESULTS

We included 258 pregnant women reporting clinically significant levels of fear of birth (guided ICBT group, 127; standard care group, 131). Of the 127 women randomized to the guided ICBT group, 103 (81%) commenced treatment, 60 (47%) moved on to the second module, and only 13 (10%) finished ≥4 modules. The levels of fear of birth did not differ between the intervention groups postintervention. At 1-year postpartum follow-up, participants in the guided ICBT group exhibited significantly lower levels of fear of birth (U=3674.00, z=-1.97, P=.049, Cohen d=0.28, 95% CI -0.01 to 0.57). Using the linear mixed models analysis, an overall decrease in the levels of fear of birth over time was found (P≤ .001), along with a significant interaction between time and intervention, showing a larger reduction in fear of birth in the guided ICBT group over time (F_1,192.538=4.96, P=.03).

CONCLUSIONS

Fear of birth decreased over time in both intervention groups; while the decrease was slightly larger in the guided ICBT group, the main effect of time alone, regardless of treatment allocation, was most evident. Poor treatment adherence to guided ICBT implies low feasibility and acceptance of this treatment.

Percutaneous Treatment with a Mucopolysaccharide Polysulphate of Experimentally Induced Subcutaneous Haematomas in Man

In a double blind trial on ten healthy volunteers, the efficacy of a topically applied mucopolysaccharide polysulphate* in the treatment of subcutaneous haematomas was assessed. Standardized haematomas were induced by subcutaneous injection of a mixture of autogenous blood and 125I-fibrinogen. The absorption of the haematoma, expressed as the removal of the labelled fibrin(ogen), could thus be objectively measured by the decrease in radioactivity.

The results show an exponential absorption of these haematomas. The absorption time was reduced to about half compared with placebo, when treated topically with mucopolysaccharide polysulphate. The difference is statistically highly significant and is also considered clinically relevant.

Women's experience of midwife-led counselling and its influence on childbirth fear: A qualitative study

BACKGROUND

Women with childbirth fear have been offered counseling by experienced midwives in Sweden for decades without evidence for its effectiveness, in terms of decrease in childbirth fear. Women are usually satisfied with the counselling. However, there is a lack of qualitative data regarding women's views about counselling for childbirth fear.

AIM

To explore women's experiences of midwife-led counselling for childbirth fear.

METHOD

A qualitative interview study using thematic analysis. Twenty-seven women assessed for childbirth fear who had received counselling during pregnancy at three different hospitals in Sweden were interviewed by telephone one to two years after birth.

FINDINGS

The overarching theme 'Midwife-led counselling brought positive feelings and improved confidence in birth' was identified. This consisted of four themes describing 'the importance of the midwife' and 'a mutual and strengthening dialogue' during pregnancy. 'Coping strategies and support enabled a positive birth' represent women's experiences during birth and 'being prepared for a future birth' were the women's thoughts of a future birth.

CONCLUSIONS

In this qualitative study, women reported that midwife-led counselling improved their confidence for birth through information and knowledge. The women experienced a greater sense of calm and preparedness, which increased the tolerance for the uncertainty related to the birthing process. This, in turn, positively affected the birth experience. Combined with a feeling of safety, which was linked to the professional support during birth, the women felt empowered. The positive birth experience strengthened the self-confidence for a future birth and the childbirth fear was described as reduced or manageable.

Association of insomnia severity with well-being, quality of life and health care costs: A cross-sectional study in older adults with chronic pain (PainS65+)

BACKGROUND

Insomnia is one of the most common complaints in chronic pain. This study aimed to evaluate the association of insomnia with well-being, quality of life and health care costs.

METHODS

The sample included 2790 older individuals (median age = 76; interquartile range [IQR] = 70-82) with chronic pain. The participants completed a postal survey assessing basic demographic data, pain intensity and frequency, height, weight, comorbidities, general well-being, quality of life and the insomnia severity index (ISI). Data on health care costs were calculated as costs per year (€ prices) and measured in terms of outpatient and inpatient care, pain drugs, total drugs and total health care costs.

RESULTS

The overall fraction of clinical insomnia was 24.6% (moderate clinical insomnia: 21.9% [95% CI: 18.8-23.3]; severe clinical insomnia: 2.7% [95% CI: 1.6-3.2]). Persons who reported clinical insomnia were more likely to experience pain more frequently with higher pain intensity compared to those reported no clinically significant insomnia. Mean total health care costs were € 8469 (95% CI: €4029-€14,271) for persons with severe insomnia compared with € 4345 (95% CI: €4033-€4694) for persons with no clinically significant insomnia. An association between severe insomnia, well-being, quality of life, outpatient care, total drugs costs and total health care costs remained after controlling for age, sex, pain intensity, frequency, body mass index and comorbidities using linear regression models.

CONCLUSIONS

Our results determine an independent association of insomnia with low health-related quality of life and increased health care costs in older adults with chronic pain.

SIGNIFICANCE

The concurrence and the severity of insomnia among older adults with chronic pain were associated with decreased well-being and quality of life, and increased health care costs to society.

Illness beliefs among patients with chronic widespread pain - associations with self-reported health status, anxiety and depressive symptoms and impact of pain

Background

Chronic widespread pain (CWP) is a disabling condition associated with a decrease in health. Illness beliefs are individual and are acquired during life. Constraining beliefs may prevent patients from regaining health. Understanding these patients’ illness beliefs may be a way to improve the health care they are offered. The aim of this study was to describe illness beliefs among patients with CWP and associations with self-reported health, anxiety and depressive symptoms, and impact of pain.

Method

In this cross-sectional study, questionnaires were sent by mail to 330 patients including socio-demographic information, the Illness Perception Questionnaire (IPQ-R), the Short-Form General Health Survey (SF-36) and the Hospital Anxiety and Depression Scale (HADS). Data were analysed using descriptive statistics, non-parametric tests and linear regression analyses.

Results

Patients experienced and related a high number of symptoms to CWP (mean (SD) 9 (3)). The patients believed their illness to be long lasting, to affect their emotional well being, and to have negative consequences for their lives. Some 72% reported having severe or very severe pain, and impact of pain according to SF-36 was negatively correlated to several illness beliefs dimensions, anxiety- and depressive symptoms. In regression analyses, the Identity, Consequences and Personal control dimensions of IPQ-R and Anxiety- and Depressive symptoms explained 32.6–56.1% of the variance in the two component scores of SF-36.

Conclusion

Constraining illness beliefs in patients with CWP are related to worse health status, especially in cases of high number of physical or mental symptoms, beliefs of negative consequences or the illness affecting them emotionally. Identification and understanding of these beliefs may reduce patients’ suffering if they are taken into consideration in rehabilitation programs and in development of new evidence-based interventions aimed at increasing health in patients with CWP.

A randomized controlled study comparing internet-based cognitive behavioral therapy and counselling by standard care for fear of birth - A study protocol

Fear of birth is a concern that requires evidence based treatment. The aim of this study is to present the protocol of a randomized controlled multi-center trial to compare internet-based cognitive therapy with counseling as standard care for pregnant women reporting fear of birth. Participants will be recruited in mid-pregnancy. Women who score 60 or above on the Fear of Birth Scale will be offered to participate in this study. Data will be collected by questionnaires including validated instruments at baseline and follow-ups at gestational weeks 30 and 36, two months and one year after birth. The primary outcome will be level of fear of birth measured with the Fear of Birth Scale at 36 weeks of gestation. Secondary outcome measures are level of fear of birth at two months and one year after giving birth, preferences for mode of birth, requests for elective cesarean section, compliance and satisfaction with treatment and birth outcomes. A power calculation based on a 20% reduction of fear implies that approximately 200 will be included in the trial. The study outlined in this protocol will be the first randomized controlled trial comparing internet-based cognitive therapy with counseling for women reporting fear of birth. An effective treatment may result in better overall health for women with fear of birth and a reduction in cesarean sections for non-medical reasons. Evidence regarding treatment options of fear of birth will also provide a greater choice for women.

Different DHEA-S Levels and Response Patterns in Individuals with Chronic Neck Pain, Compared with a Pain Free Group-a Pilot Study

Objective

To test, in this pilot study, whether DHEA-S (Dehydroepiandrosterone, sulfated form) plasma levels are lower among persons with chronic neck pain, compared to control persons, and to investigate the DHEA-S response after a physical exercise.

Subjects

Included were 12 persons with chronic neck pain and eight controls without present pain, all 18 and 65 years of age. Exclusion criteria for both groups were articular diseases or tendinosis, fibromyalgia, systemic inflammatory and neuromuscular diseases, pain conditions due to trauma, or severe psychiatric diseases.

Design and methods

The participants arm-cycled on an ergometer for 30 minutes. Blood samples were taken before, 60 minutes, and 150 minutes after this standardized physical exercise.

Results

The estimated plasma DHEA-S levels at baseline were 2.0 µmol/L (95% confidence interval [CI] 1.00; 4.01) in the pain group and 4.1 µmol/L (95% CI2.0; 8.6) in the control group, adjusted for sex, age, body mass index (BMI), and Shirom-Melamed Burnout Questionnaire (SMBQ), with a ratio of 0.48 ( P  = 0.094).

Conclusions

In this pilot study, the plasma DHEA-S levels appeared to be lower among the persons with chronic neck pain, compared with the control group. It was indicated that DHEA-S decreased during the physical exercise in the control group, and either increased or was unaffected in the chronic pain group.

Prevalence of different pain categories based on pain spreading on the bodies of older adults in Sweden: a descriptive-level and multilevel association with demographics, comorbidities, medications, and certain lifestyle factors (PainS65+)

Background and objective

There is limited knowledge about the prevalence of pain and its relation to comorbidities, medication, and certain lifestyle factors in older adults. To address this limitation, this cross-sectional study examined the spreading of pain on the body in a sample of 6611 subjects ≥65 years old (mean age = 75.0 years; standard deviation [SD] = 7.7) living in southeastern Sweden.

Methods

Sex, age, comorbidities, medication, nicotine, alcohol intake, and physical activity were analyzed in relation to the following pain categories: local pain (LP) (24.1%), regional pain medium (RP-Medium) (20.3%), regional pain heavy (RP-Heavy) (5.2%), and widespread pain (WSP) (1.7%).

Results

RP-Medium, RP-Heavy, and WSP were associated more strongly with women than with men (all p<0.01). RP-Heavy was less likely in the 80–84 and >85 age groups compared to the 65–69 age group (both p<0.01). Traumatic injuries, rheumatoid arthritis/osteoarthritis, and analgesics were associated with all pain categories (all p<0.001). An association with gastrointestinal disorders was found in LP, RP-Medium, and RP-Heavy (all p<0.01). Depressive disorders were associated with all pain categories, except for LP (all p<0.05). Disorders of the central nervous system were associated with both RP-Heavy and WSP (all p<0.05). Medication for peripheral vascular disorders was associated with RP-Medium (p<0.05), and hypnotics were associated with RP-Heavy (p<0.01).

Conclusion

More than 50% of older adults suffered from different pain spread categories. Women were more likely to experience greater spreading of pain than men. A noteworthy number of common comorbidities and medications were associated with increased likelihood of pain spread from LP to RP-Medium, RP-Heavy, and WSP. Effective management plans should consider these observed associations to improve functional deficiency and decrease spreading of pain-related disability in older adults.

A 3-Year Follow-Up of Headache Diagnoses and Symptoms in Swedish Schoolchildren

Information is sparse concerning the incidence and prognosis of headache in children from the general population, especially of tension-type headache. In this study, headache diagnoses and symptoms were reassessed in 122 out of 130 schoolchildren after 3 years. Nearly 80± of those with headache at first evaluation still reported headache at follow-up. Although the likelihood of experiencing the same headache diagnosis and symptoms was high, about one-fifth of children with tension-type headache developed migraine and vice versa. Female gender predicted migraine and frequent headache episodes predicted overall headache at follow-up. The estimated average annual incidence was 81 and 65 per 1000 children, for tension-type headache and migraine, respectively. We conclude that there is a considerable risk of developing and maintaining headache during childhood. Headache diagnoses should be reassessed regularly and treatment adjusted. Girls and children with frequent headache have a poorer prognosis and therefore intervention is particularly important in these groups.

Contrast Enhancement of Pathologic Lymph Nodes Demonstrated by Computed Tomography

Enlarged mediastinal, retroperitoneal and pelvic lymph nodes are often difficult to differentiate from vascular structures. Contrast medium is therefore used to help to discriminate arteries and veins from lymph nodes. This study was undertaken to investigate the degree to which pathologic lymph nodes become enhanced after an intravenous bolus injection of contrast medium. Computed tomography was performed in 25 patients with enlargement of retroperitoneal lymph nodes due to primary lymphoproliferative disease or metastases. A dynamic sequence of a well delineated lymph node was obtained over a period of two minutes. Contrast enhancement was seen in all lymph nodes, but of varying degree. The enhancement was correlated to that observed in the inferior vena cava. Most examined lymph nodes showed slight or moderate enhancement, but in five instances strong enhancement, more than 75 per cent of that of the vena cava, was found. These nodes could possibly have been misinterpreted as blood vessels.

Circulating cartilage oligomeric matrix protein in juvenile idiopathic arthritis

OBJECTIVES

Raised serum cartilage oligomeric matrix protein (sCOMP) has been reported to predict erosive disease in early rheumatoid arthritis (RA). In juvenile idiopathic arthritis (JIA), subnormal sCOMP levels have been associated with ongoing inflammation and growth retardation. In this study we aimed to assess sCOMP, C-reactive protein (CRP), and insulin-like growth factor (IGF)-1 in children/adolescents with JIA and in referents.

METHOD

We enrolled 52 JIA patients at planned outpatient visits and 54 inpatients with ongoing infection ('infection referents'). A total of 120 referents testing negative for immunoglobulin (Ig)E-mediated allergy ('IgE referents') served as controls. All serum samples were analysed for COMP, IGF-1, and CRP.

RESULTS

The average sCOMP level was highest among the IgE referents and lowest among the infection referents. In the JIA patients, the level of sCOMP was not associated with the level of CRP or with clinical signs of disease activity.

CONCLUSIONS

The results of this study do not support routine clinical analysis of sCOMP levels in patients with JIA.

Prevalence of Different Pain Categories Based on Pain Spreading in Older Adults in Sweden: A Multilevel Association With Socio-Demographic Characteristics, Comorbidities and Drug Consumption (Pain S65+)

Introduction

Understanding of factors related to chronic pain in elderly is limited.

Objectives and aims

To estimate the prevalence of pain categories based on spreading of pain on the body and to investigate how such spreading is related to demographic variables, pain intensity, comorbidities and medication in an elderly general population in southeastern Sweden.

Methods

A total of 6611 adults aged ≥ 65 years participated (mean age = 76.2; SD = 7.4). Pain categories were assessed by a self-reported postal questionnaire covering 45 anatomical predefined pain regions along with demographics, pain intensity during previous seven days, comorbidities and medication. Poisson regression models with robust error variance were used for data analyzing.

Results

The prevalence of pain spreading categories was: chronic local pain (CLP) 16%; chronic regional pain medium (CRP-Medium) 17%; chronic regional pain heavy (CRP-Heavy) 5% and chronic widespread pain (CWSP) 2%. Overall, increased prevalence for CRP-Heavy and CWSP in subjects 75–79 years old compared to those 65–69, 70–74, 80–84 and ≥ 85 years were revealed. In men, 75–79 years old, CRP-Heavy was more common than in the other pain categories. In women, 75–79 years old CWSP, was more common than in the other pain categories. Pain intensity was strongly associated with all pain categories (P < 0.001). CLP was associated with trauma, rheumatoid arthritis, cancer, prescribed and non-prescribed analgesics. CRP-Medium was associated with rheumatoid arthritis, CRP-Heavy with rheumatoid arthritis and lung diseases and CWSP with rheumatoid arthritis and prescribed analgesics (P < 0.001).

Conclusions

Our findings elucidate heterogeneity of pain in elderly which has to be further investigated.

Accumulation of substances with melanin affinity to the internal ear. Therapeutic or ototoxic mechanism?

The capacity of the melanin in the internal ear to accumulate and retain labelled lidocaine, bupivacaine and chlorpromazine after intravenous and intraperitoneal injection was examined by whole-body autoradiography. Both young pigmented hooded rats and albino rats were studied. In the pigmented rats chlorpromazine showed the greatest accumulation, which was more pronounced in the cochlea than in the vestibular portion. The other two substances were evenly distributed in the internal ear. After a single injection of chlorpromazine and of bupivacaine these substances were still bound to the melanin of the internal ear after 14 days, which was the longest survival time. Lidocaine, on the other hand, had disappeared after only 4 days. In albino animals there was very weak, transient uptake of chlorpromazine and bupivacaine, but not of lidocaine, in the internal ear. In studies in vitro on isolated bovine eye melanin there was considerably greater adsorption of chlorpromazine than of lidocaine and bupivacaine.

Comparative metabolomics of muscle interstitium fluid in human trapezius myalgia: an in vivo microdialysis study

Purpose

The mechanisms behind trapezius myalgia are unclear. Many hypotheses have been presented suggesting an altered metabolism in the muscle. Here, muscle microdialysate from healthy and myalgic muscle is analysed using metabolomics. Metabolomics analyse a vast number of metabolites, enabling a comprehensive explorative screening of the cellular processes in the muscle.

Methods

Microdialysate samples were obtained from the shoulder muscle of healthy and myalgic subjects that performed a work and stress test. Samples from the baseline period and from the recovery period were analysed using gas chromatography—mass spectrometry (GC–MS) together with multivariate analysis to detect differences in extracellular content of metabolites between groups. Systematic differences in metabolites between groups were identified using multivariate analysis and orthogonal partial least square discriminate analysis (OPLS-DA). A complementary Mann–Whitney U test of group difference in individual metabolites was also performed.

Results

A large number of metabolites were detected and identified in this screening study. At baseline, no systematic differences between groups were observed according to the OPLS-DA. However, two metabolites, l-leucine and pyroglutamic acid, were significantly more abundant in the myalgic muscle compared to the healthy muscle. In the recovery period, systematic difference in metabolites between the groups was observed according to the OPLS-DA. The groups differed in amino acids, fatty acids and carbohydrates. Myristic acid and putrescine were significantly more abundant and beta-d-glucopyranose was significantly less abundant in the myalgic muscle.

Conclusion

This study provides important information regarding the metabolite content, thereby presenting new clues regarding the pathophysiology of the myalgic muscle.

Experimental myalgia induced by repeated infusion of acidic saline into the human masseter muscle does not cause the release of algesic substances

BACKGROUND

Animal studies have shown that two repeated intramuscular injections of acidic saline induce mechanical allodynia that lasts for 4 weeks with spread to the contralateral side. In this study, we tested the hypothesis that two repeated intramuscular infusions of acidic saline into the human masseter muscle is associated with pain, mechanical allodynia and release of algesic substances. Eighteen healthy volunteers participated. On day 1, 2.5 mL of acidic saline (pH 3.3) was infused into one of the masseter muscles and isotonic saline (pH 6.0) into the other (randomized and single-blind). Two days later, intramuscular microdialysis was performed to sample serotonin, glutamate, pyruvate, lactate and glucose, during which the saline infusions were repeated. Pain and pressure pain thresholds (PPTs) were recorded before and after infusions on both days.

RESULTS

Pain intensity induced by the infusions was higher after acidic than that after isotonic saline (p < 0.05). PPTs were decreased on both sides after microdialysis compared with baseline day 1 (p's < 0.05), but there were no differences in PPTs between sides at any time point. The levels of serotonin, glutamate, pyruvate, lactate or glucose did not change significantly during microdialysis.

CONCLUSION

Infusion of acidic saline caused low levels of muscle pain, but no mechanical allodynia and no increased release of algesic substances. The value of this model appears modest, but future studies could be performed with larger sample size and higher flow rate before definite conclusions about the validity of the model for craniofacial myalgia can be drawn.

One-piece zirconia oral implants: one-year results from a prospective cohort study. 1. Single tooth replacement

AIM

To investigate the clinical and radiographic outcome of a one-piece zirconia oral implant for single tooth replacement after 1 year.

MATERIALS AND METHODS

A total of 65 patients received a one-stage implant surgery with immediate temporization. Standardized radiographs were taken at implant insertion and after 1 year to monitor peri-implant bone loss. A univariate analysis of the influence of different baseline parameters on marginal bone loss from implant insertion to 12 months was performed. Soft tissue parameters were evaluated at prosthesis insertion and at the 1-year follow-up.

RESULTS

After 1 year, three implants were lost, giving a cumulative survival rate of 95.4%. The marginal bone loss after 1 year was 1.31 mm. Thirty-four per cent of the implants lost at least 2 mm bone, and 14% more than 3 mm. The univariate analysis could not depict any parameter influencing marginal bone loss. Probing depth, Clinical Attachment Level, Bleeding and Plaque Index decreased over 1 year.

CONCLUSIONS

The cumulative survival rate of the presented ceramic implant was comparable to the reported survival rate of titanium implants when immediately restored. However, the frequency of increased radiographic bone loss (>2 mm) after 1 year was considerably higher as compared to conventional two-piece titanium implants. The presented zirconia implant can therefore not be recommended for clinical usage.

Effect of infancy-onset dietary intervention on salivary cholesterol of children: a randomized controlled trial

This study investigated salivary cholesterol of children from 6 to 16 years of age in response to dietary intervention. One thousand sixty-two infants started in the prospective, randomized project. At 3 years of age, every fifth child was invited into the study (n=178). Of these, 148 enrolled, and 86 completed the oral sub-study at 16 years of age. The intervention aimed at restricting the child's saturated fat and cholesterol intake. Control children received no special recommendations. Every third year, paraffin-stimulated saliva samples (10.0 mL) were collected for cholesterol assays. Nutrient intakes and serum total cholesterol concentrations were regularly followed up by means of 4-day food records and blood samples. Intake of saturated fatty acids (SAFA) was lower in the intervention than in the control group (p<0.001). Salivary cholesterol concentration increased from 1.9 (±1.1) µmol/L at 6 years of age to 16.0 (±9.0) µmol/L at 16 years of age. The increase was smaller in the intervention than in the control group (p<0.001). The ratios of salivary to serum cholesterol concentrations tended to be higher in boys than in girls (p=0.07). Thus, dietary intervention was reflected in children's salivary cholesterol values more sensitively than in serum cholesterol values. (clinicaltrials.gov NCT00223600).

Effects of resistance training on endurance capacity and muscle fiber composition in young top-level cyclists

Equivocal findings exist on the effect of concurrent strength (S) and endurance (E) training on endurance performance and muscle morphology. Further, the influence of concurrent SE training on muscle fiber-type composition, vascularization and endurance capacity remains unknown in top-level endurance athletes. The present study examined the effect of 16 weeks of concurrent SE training on maximal muscle strength (MVC), contractile rate of force development (RFD), muscle fiber morphology and composition, capillarization, aerobic power (VO2max), cycling economy (CE) and long/short-term endurance capacity in young elite competitive cyclists (n=14). MVC and RFD increased 12-20% with SE (P<0.01) but not E. VO2max remained unchanged. CE improved in E to reach values seen in SE. Short-term (5-min) endurance performance increased (3-4%) after SE and E (P<0.05), whereas 45-min endurance capacity increased (8%) with SE only (P<0.05). Type IIA fiber proportions increased and type IIX proportions decreased after SE training (P<0.05) with no change in E. Muscle fiber area and capillarization remained unchanged. In conclusion, concurrent strength/endurance training in young elite competitive cyclists led to an improved 45-min time-trial endurance capacity that was accompanied by an increased proportion of type IIA muscle fibers and gains in MVC and RFD, while capillarization remained unaffected.
