- Objectives: Violence is regarded as a major health issue in an increasing amount of literature and is known as an important factor in women's ill health. Little however is known about violence against young men and women and its impact on their health. The principal aim of this study was to analyze health outcomes and health care utilization as reported among men and women aged 18-25 exposed and not exposed to physical and/or emotional violence. Study design: A cross-sectional national health survey in Sweden. Methods: Postal questionnaires were sent to nearly 3,000 men and women. Three questions were used to ask about violence. Sociodemographic characteristics for those exposed to violence during the past 12 months were analyzed and compared to those not exposed. Crude and adjusted odds ratios were calculated for health outcomes and medical care utilization. Results: Increased odds ratios were found for most health outcomes, and health care utilization for those exposed to violence compared to non-exposed. After adjusting for socioeconomic factors, smoking, and use of alcohol and cannabis, most variables were principally unchanged for women but considerably lower for men. Socioeconomic factors, smoking, and the use of drugs were all correlated to victimization. Conclusions: A strong association between those exposed to violence and physical and mental ill health was demonstrated also after adjusting for possible confounders, specifically for women. It is time to include questions about violence in public health questionnaires aimed at young people, but also to start asking about it more frequently in health care settings.

- Background: Early detection of coronary atherosclerosis using coronary computed tomography angiography (CCTA), in addition to coronary artery calcification (CAC) scoring, may help inform prevention strategies. We used CCTA to determine the prevalence, severity, and characteristics of coronary atherosclerosis and its association with CAC scores in a general population.Methods: We recruited 30 154 randomly invited individuals age 50 to 64 years to SCAPIS (the Swedish Cardiopulmonary Bioimage Study). The study includes individuals without known coronary heart disease (ie, no previous myocardial infarctions or cardiac procedures) and with high-quality results from CCTA and CAC imaging performed using dedicated dual-source CT scanners. Noncontrast images were scored for CAC. CCTA images were visually read and scored for coronary atherosclerosis per segment (defined as no atherosclerosis, 1% to 49% stenosis, or ≥50% stenosis). External validity of prevalence estimates was evaluated using inverse probability for participation weighting and Swedish register data.Results: In total, 25 182 individuals without known coronary heart disease were included (50.6% women). Any CCTA-detected atherosclerosis was found in 42.1%; any significant stenosis (≥50%) in 5.2%; left main, proximal left anterior descending artery, or 3-vessel disease in 1.9%; and any noncalcified plaques in 8.3% of this population. Onset of atherosclerosis was delayed on average by 10 years in women. Atherosclerosis was more prevalent in older individuals and predominantly found in the proximal left anterior descending artery. Prevalence of CCTA-detected atherosclerosis increased with increasing CAC scores. Among those with a CAC score >400, all had atherosclerosis and 45.7% had significant stenosis. In those with 0 CAC, 5.5% had atherosclerosis and 0.4% had significant stenosis. In participants with 0 CAC and intermediate 10-year risk of atherosclerotic cardiovascular disease according to the pooled cohort equation, 9.2% had CCTA-verified atherosclerosis. Prevalence estimates had excellent external validity and changed marginally when adjusted to the age-matched Swedish background population.Conclusions: Using CCTA in a large, random sample of the general population without established disease, we showed that silent coronary atherosclerosis is common in this population. High CAC scores convey a significant probability of substantial stenosis, and 0 CAC does not exclude atherosclerosis, particularly in those at higher baseline risk.

- ABSTRACT: INTRODUCTION: Change in bone mineral density (BMD) in the hand, as evaluated by digital X-ray radiogrammetry (DXR) of the II-IV metacarpal bones, has been suggested to predict future joint damage in rheumatoid arthritis (RA). This study's objective was to investigate if DXR-BMD loss early in the disease predicts development of joint damage in RA patients followed for up to 20 years. METHODS: 183 patients (115 women and 68 men) with early RA (mean disease duration 11 months) included from 1985 to 1989 were followed prospectively (the Lund early RA cohort). Clinical and functional measures were assessed yearly. Joint damage was evaluated according to the Larsen score on radiographs of hands and feet taken in years 0 to 5, 10, 15 and 20. These radiographs were digitized and BMD of the II-IV metacarpal bones was evaluated by DXR (Sectra, Linkoping. Sweden). Early DXR-BMD change rate (bone loss) per year calculated from the first 2 radiographs taken on average 9 months apart (SD 4.8) were available for 135 patients. Mean values of right and left hand were used. RESULTS: Mean early DXR-BMD loss during the first year calculated was -0.023 g/cm2 (SD 0.025). Patients with marked bone loss, i.e. early DXR-BMD loss above the median for the group, had significantly worse progression of joint damage at all examinations during the 20-year period. CONCLUSIONS: Early DXR-BMD progression rate predicted development of joint damage evaluated according to Larsen at year one and further onwards up to 20 years in this cohort of early RA patients.

- Before the introduction of lidocaine, the choice of local anesthetics was limited Procaine was most commonly used and offered less toxicity than cocaine, but it had a short duration faction Tetracaine had substantial systemic toxicity, limiting its use largely to spinal anesthesia An agent with low toxicity, a quick onset, and a longer duration of action was needed This article reports the initial clinical trials with the newly synthesized lidocaine The first trials were wheal tests on the forearms of human volunteers Lidocaine anesthesia duration was markedly longer than that produced by procaine Lidocaine was first tested for infiltration anesthesia in many short procedures performed in the emergency department, followed by major procedures, including those for goiter and hernia in the operating room Consistent success was observed in both environments Lidocaine was then tested for conduction anesthesia using brachial plexus and mandibular, sacral, and paravertebral blocks Its onset as again substantially faster and longer lasting than that of procaine Lidocaine also provided good spinal and surface anesthesia of the cornea

- BACKGROUND: Accurate age- and sex-related normal reference values of ventricular structure and function are important to determine the level of dysfunction in patients. The aim of this study therefore was to document normal age range sex-related measurements of LV structural and functional measurements to serve such purpose.METHODS: We evaluated left ventricular structure and function in 293 healthy subjects between 20 and 90 years with equally distributed gender. Doppler echocardiography was used including measure of both systolic and diastolic functions.RESULTS: Due to systolic LV function, only long axis function correlated with age (r = 0·55, P<0·01) and the correlation was stronger in females. Concerning diastolic function, there was a strong age correlation in all parameters used (r = 0·40-0·74, P<0·001). Due to LV structural changes over age, females showed a larger reduction in end-diastolic volumes, but no or trivial difference in wall thickness after the age of 60 years.CONCLUSION: Age is associated with significant normal changes in left ventricular structure and function, which should be considered when deciding on normality. These changes are related to systemic arterial changes as well as body stature, thus reflecting overall body ageing process. Furthermore, normal cardiac ageing in females might partly explain the higher prevalence of heart failure with preserved ejection in females.

- The nonobese diabetic ( NOD) Nss1 and Idd5 loci have been associated with sialadenitis development in mice. In this study the NOD Nss1 and Idd5 loci were backcrossed onto the healthy control strain B10. Q by using the speed congenic breeding strategy, resulting in three congenic strains: B10. Q. Nss1, B10. Q. Nss1/Idd5 heterozygous and B10. Q. Nss1/Idd5 homozygous. We investigated the effects of the Nss1 and Idd5 loci on sialadenitis and gene expression in NOD congenic mice. One submandibular salivary gland from each mouse was used for histological analysis of sialadenitis, whereas the contralateral salivary gland was used for gene expression profiling with the Applied Biosystems Mouse Genome Survey chip v. 1.0. The results were validated using quantitative reverse transcriptase PCR. The NOD Nss1 and Idd5 loci had clear influence on the onset and progression of sialadenitis in congenic mice. Double congenic mice exhibited the most severe phenotype. We successfully identified several genes that are located in the NOD congenic regions to be differentially expressed between the congenic strains and the control strain. Several of these were found to be co-regulated, such as Stat1, complement component C1q genes and Tlr12. Also, a vast contingency of interferon-regulated genes ( such as Ltb, Irf7 and Irf8) and cytokine and chemokine genes ( such as Ccr7 and Ccl19) were differentially expressed between the congenic strains and the control strain. Over-representation of inflammatory signalling pathways was observed among the differentially expressed genes. We have found that the introgression of the NOD loci Nss1 and Idd5 on a healthy background caused sialadenitis in NOD congenic mouse strains, and we propose that genes within these loci are important factors in the pathogenesis. Furthermore, gene expression profiling has revealed several differentially expressed genes within and outside the NOD loci that are similar to genes found to be differentially expressed in patients with Sjogren's syndrome, and as such are interesting candidates for investigation to enhance our understanding of disease mechanisms and to develop future therapies.

To tear and to heal : pelvic floor dysfunction and childbirth
- 2023

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Up to 80% of women are affected by a perineal laceration after their first vaginal birth. An estimated 40–50% of lacerations involve the perineal muscles, and up to 7% are obstetric anal sphincter injuries (OASI). There is a lack of knowledge about the extent of short-term complications such as pelvic floor dysfunction (PFD) following spontaneous or iatrogenic pelvic floor trauma. Women’s experiences of daily life after childbirth complicated by OASI is poorly understood. Three-dimensional endoanal ultrasonography (3D-EAUS) is a welldocumented method for evaluating damage to the anal sphincter in other contexts. Adding ultrasonography to standard clinical examination has revealed injuries previously missed, and research evaluating diagnostic methods for the routine screening of OASI has been called for.Aim: This thesis aims to evaluate the diagnostics of OASI, determine if the degree of perineal injury or anal sphincter defects after childbirth are associated with pelvic dysfunction, and explore women’s experiences of OASI.Methods Studies I and IV were prospective cohort-studies to evaluate any association between perineal tear or sphincter defect to PFD. Study II was an interview study addressing women’s experiences of OASI by qualitative content analysis. Study III was a cross-sectional study designed to examine the utility of endoanal ultrasound to detect OASI. Participants were clinically examined after birth and 3D-EAUS was performed immediately after giving birth and 3 months postpartum. PFD was evaluated using a web-based questionnaire one year after delivery.Results: A total of 511 women completed the one-year questionnaire (Study I) and a purposive sample of 11 women were invited to take part in Study II. In Study III, 680 women underwent a clinical examination and 3D-EAUS recording immediately after birth. In Study IV, 239 women who attended all follow-ups were included. PFD was experienced by women with a perineal laceration of any grade, but also those with an intact perineum. Dyspareunia and urinary incontinence were the most common problems. Women with OASI had a higher risk for developing vi symptoms of prolapse, urinary urge incontinence, dyspareunia, and pain as well as experiencing a negative impact on their daily life. Elements that negatively influenced women’s experiences of OASI were pain and symptoms of PFD, normalisation of symptoms by healthcare providers, and unrealistic expectations about this period in life. 3D-EAUS immediately after delivery had poor sensitivity and specificity in detecting clinically diagnosed OASI. Postpartum anal sphincter defects were associated with genital pain and dyspareunia.Conclusions: OASI is an evident risk factor for pelvic floor dysfunction after childbirth, but symptoms of pelvic floor disorder were found to be common, even in women with mild to moderate perineal laceration. OASI has a negative impact on how a woman experiences relationships, social contact, and sexuality. Using 3D-EAUS in a maternity ward to diagnose OASI is demanding. Staff generally have little experience in 3D-EAUS. There are also difficulties in obtaining good image quality, due to local oedema, bleeding, positioning of the woman, and unintentional movements. These factors all complicate the interpretation of images.
