Abstract [en]

Background:

Vitamin D deficiency-induced osteomalacia remains underexplored, despite the substantial migration to northern sun-deprived latitudes. In women, osteomalacia may impair smooth and striated muscle function and disrupt the birth canal. This study aimed to investigate the associations and effect estimates of biochemical osteomalacia on perinatal outcomes.

Methods:

A prospective cohort study was conducted to examine 71 Swedish and 52 Somali women during pregnancy and breastfeeding, addressing the heightened risk of severe vitamin D deficiency among Somali women. The baseline data comprised blood samples, questionnaires and clinical examination. Two years later, outcome variables were collected and comprised diagnostic codes for delivery methods. Women with miscarriage, stillbirth, or relocation from the region were excluded. Biochemical osteomalacia reaffirmed by signs and symptoms was diagnosed based on a non-invasive, non-radiation protocol. Associations between biochemical osteomalacia and delivery outcomes were analyzed using multinomial logistic regression, adjusted for a minimal set of confounders.

Results:

In the cohort 20 women, 19 Somali and one Swedish, were diagnosed with biochemical osteomalacia. Among women with biochemical osteomalacia, the adjusted odds ratio (aOR) for instrumental-assisted delivery was 4.92 (95 % CI 1.30-18.65) and the aOR for vacuum extractions was 16.16 (95 % CI 1.20-217.55).

Conclusions:

Biochemical osteomalacia was associated with a higher incidence of emergency instrumental delivery procedures, including an increased likelihood of vacuum-assisted delivery and emergency Caesarean sections. Primary healthcare staff play a vital role in screening for vitamin D deficiency during pregnancy and breastfeeding period, as well as initiating supplementation to mitigate the risk of adverse perinatal outcomes.

Abstract [en]

Objective

Many adolescent males report negative experiences of consultations with general practitioners (GPs), which contrasts with the importance of patient-centredness that GPs themselves emphasise. A better understanding of this discrepancy might facilitate improvements. The aim was to explore and describe adolescent males’ encounters with GPs in Swedish primary healthcare centres using a lifeworld perspective.

Design

Qualitative lifeworld-based study. Video-recorded observations were analysed using a phenomenological-hermeneutical method.

Setting

Two primary healthcare centres in mid-Sweden.

Subjects

Nine males aged 15 to 19, video-recorded during their encounters with GPs in March through May 2022.

Findings

Adolescent males navigate between being children in need of parental support and men who can take initiative and responsibility. They face cognitive, emotional, and relational demands, the complexity of which renders them particularly vulnerable. When feeling exposed and not knowing what to expect, they struggle to make themselves understood, and to understand what the GP is saying and what is happening. The difficulties that they have disclosed to the GP in trust need to be recognised and carefully acted upon. Thus the GP must respond appropriately to this complex mix of vulnerabilities to prevent feelings of disappointment or of having exposed themselves in vain.

Conclusion

The complexity of encounters with adolescent males imposes great demands on GPs to identify and adapt to their individual needs. A proper ethical response involves helping them navigate the challenges of the consultation while also respecting them as persons and meeting their age-dependent needs.

Abstract [en]

As available treatments in obstructive sleep apnea (OSA) are all associated with side effects or adherence problems, there is a need for alternative treatment options.

In this randomised, open, parallel-group intervention study the effect of head extension by cervical collar was evaluated in patients with moderate OSA. 

One hundred patients with moderate OSA (apneas and hypopneas per estimated hours asleep = respiratory events index: 15–30) were randomised to either lifestyle intervention (LS) or cervical collar in combination with lifestyle intervention (CC/LS). Both groups received lifestyle advice. In addition, the treatment group were treated with a cervical collar, which allows adjustment of head extension, during sleep. Assessment with questionnaires and polygraphy were performed at baseline and after 6 ± 2 weeks.

A linear regression model was used to assess a total effect on respiratory events index, which was the primary endpoint. 

In the intention to treat (ITT) analysis, the CC/LS group decreased their respiratory events index (P = 0.008) and oxygen desaturation index (P = 0.008) more than the LS group with a mean difference of -4.5 and -4.3, respectively. In the sub-analysis, there was a clear effect on respiratory events index in the supine position (mean difference between the groups -9.1, p=0.018) but not on non-supine AHI (-2.3, p=0.17).  

We conclude that head extension by cervical collar during sleep resulted in improved respiratory events index and oxygen desaturation index values in patients with moderate OSA. Cervical collar can be a second-line treatment option in this group, especially in positional OSA.

Abstract [en]

Background

Generalized joint hypermobility is an inherited collagen phenotype based on clinical assessments of joint mobility. However, there is no international consensus to define generalized joint hypermobility, both considering which joint mobility tests should be included and limits for joint hypermobility.

Objectives

The primary aim of the study was to identify a subset of joint mobility tests to define generalized joint hypermobility. A further aim was to evaluate standardized limits for the classification of hypermobility in different joint types throughout the body.

Methods

A total of 255 early pregnant women were included in the study. Joint mobility was measured according to a structured protocol. Correlation and principal component analysis were used to find a subset of joint mobility tests. To classify hypermobility in each joint mobility test, five different standard deviation levels plus 0.84, plus 1.04, plus 1.28, plus 1.64 and plus 2 were used, corresponding to 20%, 15%, 10%, 5% and 2.5% of the normal distribution.

Results

No subset of joint mobility test could define generalized joint hypermobility. The higher the standard deviation levels, the higher the limit to classify joint hypermobility and the lower the prevalence. As a result of no subset of joint mobility tests were found to define generalized joint hypermobility, different combinations of major and minor joints in upper and lower limbs and the axial skeleton, were systematically developed. These combinations were evaluated for each standard deviation level, resulting in a prevalence of generalized joint hypermobility between 0% and 12.9% and a clear variation in how the hypermobile joint mobility tests were distributed.

Conclusion

It is probably not possible to choose a subset of joint mobility tests to define GJH. In order not to overlook generalized joint hypermobility, a broader assessment of different joint types and sizes of joints appears to be needed. The prevalence of generalized joint hypermobility is dependent on joint hypermobility limit and the chosen combination of joint mobility tests.

Abstract [en]

Background

Many adolescent males visit a general practitioner regularly, yet many report unmet health needs and negative experiences. This indicates a gap between provided healthcare and the needs of adolescent males. In order to improve adolescent males’ possibilities to discuss their health concerns with general practitioners, the study’s aim was to explore and describe how adolescent males understand and assign meaning to their experiences of consultations with general practitioners.

Methods

This qualitative study was conducted at two healthcare centres in mid-Sweden in 2022. Nine males 15 to 19 years old described their experiences in semi-structured interviews immediately after consulting a general practitioner, regardless of reason for the consultation and whether or not accompanied by a parent. The analysis was guided by thematic analysis according to Braun & Clarke and reflective lifeworld theory’s concepts of openness and sensitivity.

Results

One overarching theme, To be listened to, and three themes were developed: To handle insecurity and uneasiness, To be understood and cared for, and To get parental support on his terms. In a good appointment, the general practitioner cares about him, listens attentively, and takes him seriously. More importantly, the general practitioner’s understanding permeates the consultation, so that all aspects of it is adapted to him. The adolescent males doubted their ability to express themselves and to understand what would happen in the consultation, and therefore feared being dismissed without receiving any help. Such difficulties may be due to unfinished neurocognitive development and inexperience. They struggled with embarrassment, partly due to notions of masculinity, and strived to balance their needs of parental support, privacy, and being the one that the doctor listens to.

Conclusions

We argue that adolescent males are particularly vulnerable due to on-going neurocognitive and emotional development, inexperience, and notions of masculinity. However, good experiences can be generated through rather simple means. Adolescent males need individual adaptations demonstrating that they are cared for, understood and taken seriously. Furthermore, they need an unhurried pace to facilitate understanding, verbal affirmations to mitigate embarrassment, and help in navigating parental involvement.

Abstract [en]

Study objectives: This study aimed to investigate the effect of telemonitoring compared with standard clinic visits on adherence to continuous positive airway pressure (CPAP) treatment after 6 months. In addition, the impact of other factors including CPAP side effects on treatment adherence were assessed.

Methods: Consecutive patients (n = 217) who were prescribed CPAP treatment for obstructive sleep apnea were randomized to either telemonitoring or standard-care follow-up. All patients were followed up 6 months after treatment started. Clinical/anthropometric variables, socioeconomical and lifestyle factors, psychological distress, daily function, and personality traits along with CPAP side effects were assessed. Differences between groups were analyzed using 2-sample t-test, chi-square test, or Fisher's exact test. Regression modeling was used to explore associations between dependent and independent variables.

Results: There were no differences in CPAP adherence between telemonitoring and standard-care groups after 6 months (53.2% vs 48.7%; P = .54). CPAP side effects such as dry throat (odds ratio = 2.17; 95% confidence interval = 1.25-3.70), increased awakenings (2.50; 1.31-4.76), and exhaling problems (3.70; 1.25-10.1) were independently associated with low CPAP adherence, although these associations were weakened when adding smoking to the model. No other baseline or follow-up factors were associated with CPAP adherence at 6 months.

Conclusions: We could not show that telemonitoring follow-up improved adherence levels. Dry throat, increased awakenings, exhaling problems, and smoking had negative effects on CPAP adherence. Preventing side effects and assessing smoking status is therefore of importance when wanting to improve CPAP adherence.
