BACKGROUND: Hazardous alcohol use increases the risk of hypertension but is underdetected in primary health care patients. Use of the biomarker phosphatidylethanol (PEth), which reflects the last two to three weeks of alcohol consumption, is increasing in Swedish primary health care, but studies from that context are scarce or missing. AIM: Explore general practitioners' (GPs') experiences of using PEth to identify hazardous alcohol use in the context of managing hypertension. DESIGN & SETTING: A qualitative study of GPs (n=12) experienced in using PEth in hypertension management who were recruited at Swedish primary health care centres in 2021. METHOD: The GPs participated in five focus groups interviews. A questioning route was used. The interviews were audio recorded, transcribed verbatim, and analysed with inductive qualitative content analysis. RESULTS: The overall theme I don't hesitate anymore reflects the disappearance of GPs' fear that the PEth result might upset the patient, as this rarely occurred and that the positive effects of PEth predominated in the findings. The theme is underpinned by four sub-themes: serving as an eyeopener, improving the dialogue, using with care, and learning by doing. CONCLUSION: PEth is a useful tool that changed GPs' routines for addressing alcohol and identifying hazardous alcohol use in patients with hypertension managed in primary health care. The GPs advocated adopting PEth as a routine test in the treatment of hypertension. However, PEth needs to be used with care to maximise benefit and minimise harm.

BACKGROUND: Temporomandibular disorders (TMD) are associated with musculoskeletal diseases (MSD), mental and behavioural disorders (MBD), and patients with TMD have been shown to have 2-3 times more days of sick leave (SL) and disability pension (DP) than the general population. MSD and MBD are two of the most common causes for SL and DP, and the association between TMD and the influence of comorbidities on the need for SL and DP among TMD patients need further clarification. This study investigates the impact of MSD and MBD comorbidity on SL and DP among TMD patients diagnosed in a hospital setting and/or surgically treated. METHODS: All incident TMD patients diagnosed or treated in a hospital setting between 1998 and 2016 and aged 23-59 were included. A non-exposed comparison cohort was collected from the general population. The cohorts were grouped based on the presence of comorbidity: No comorbidity (Group I); MSD comorbidity (Group II); MBD comorbidity (Group III); and combined MSD and MBD comorbidity (Group IV). Main outcomes were mean annual days of SL and DP, and statistical analysis was conducted using generalized estimated equations. RESULTS: TMD subjects with no comorbidities (Group I) and with MSD/MBD comorbidity (Group II and III) were 2-3 times more often on SL and DP than the corresponding groups from the general population. However, in the group with both MSD and MBD comorbidity (Group IV), the difference between the TMD subjects and the general population was diminishing, suggesting an additive effect. CONCLUSION: TMD patients are more dependent on SL and DP benefits compared to general population and the difference remains even after considering MSD and MBD comorbidity. In individuals with combined MSD and MBD comorbidity, concurrent TMD has less impact on the need for social insurance benefits. The results accentuate the impact TMD has on the patients' impaired ability to return to work and why TMD should be recognized as having a substantial impa

BACKGROUND AND PURPOSE: Several randomized trials have demonstrated the lack of effect of arthroscopic lavage as treatment for knee osteoarthritis (OA). These results have in turn resulted in a change in Swedish guidelines and reimbursement. We aimed to investigate the use of knee arthroscopies in Sweden between 2002 and 2016. Patient demographics, regional differences, and the magnitude of patients with knee OA undergoing knee arthroscopy were also analyzed. PATIENTS AND METHODS: Trends in knee arthroscopy were investigated using the Swedish Hospital Discharge Register (SHDR) to conduct a nationwide register-based study including all adults (>18 years of age) undergoing any knee arthroscopy between 2002 and 2016. RESULTS: The total number of knee arthroscopies performed during the studied period was 241,055. The annual surgery rate declined in all age groups, for males and females as well as patients with knee OA. The incidence dropped from 247 to 155 per 105 inhabitants. Over 50% of arthroscopies were performed in metropolitan regions. CONCLUSION: We showed a dramatic decline in knee arthroscopy. There is variability in the surgery rate between males and females and among the regions of Sweden.

Purpose: There is a well-known association between mental and behavioral disorders (MBD) and temporomandibular disorder (TMD), although the association has not been established in population-based samples. This study aimed to investigate this relationship using national population-based registry data. Patients and Methods: This case-control study used prospectively collected data from Swedish national registries to investigate exposure to MBD and the probability of developing TMD in all Swedish citizens with hospital-diagnosed or surgically treated TMD between 1998 and 2016. Odds ratios were calculated using conditional logistic regression adjusted for educational level, living area, country of birth, musculoskeletal comorbidity, and history of orofacial/neck trauma. Results: A statistically significant association between MBD and TMD was found for mood affective disorders (OR 1.4), neurotic, stress-related and somatoform disorders (OR 1.7), behavioral syndromes associated with psychological disturbances and physical factors (OR 1.4), disorders of adult personality and behavior (OR 1.4), disorders of psychological development (OR 1.3), behavioral and emotional disorders with onset usually occurring in childhood and adolescence (OR 1.4), and unspecified mental disorder (OR 1.3). The association was stronger for TMD requiring surgery, with the strongest association in patients with disorders of psychological development (OR 2.9). No significant association was found with schizophrenia, schizotypal and delusional disorders, or mental retardation. Conclusion: The findings indicate an increased probability of TMD among patients with a history of certain MBD diagnoses, and a stronger association with TMD requiring surgery, specifically repeated surgery. This highlights the need for improved preoperative understanding of the impact of MBD on TMD, as TMD and chronic pain itself may have a negative impact on mental health.

BACKGROUND: Temporomandibular disorders (TMD) are common and affect approximately 10% of the adult population. TMD is usually associated with headache, pain in the masticatory muscles and/or the temporomandibular joint, clicking or crepitations during mandibular movement as well as painful and/or reduced mouth opening. This study aimed to investigate the level TMD-patients use social insurance benefits before and after their first time of diagnosis or first surgical event, compared to the general population. Furthermore, the aim was to investigate the differences in the use of social insurance benefits between surgically and non-surgically treated TMD-patients that were diagnosed in a hospital setting. METHODS: All Swedish citizens aged 23-59 diagnosed with TMD in a hospital setting and/or surgically treated for the condition during 1998-2016 were identified via the Swedish National Board of Health and Welfare. A non-exposed comparison cohort was collected via the Total Population Registry. Outcome and sociodemographic data were collected via Statistics Sweden. Main outcome was annual net days on sick leave and disability pension five years before (-T5) and five years after (T5) diagnosis and/or surgical treatment (T0). Regression analysis was conducted with generalized estimated equations. RESULTS: The study included 219 255 individuals (73% female) - 19 934 in the exposed cohort and 199 321 in the comparison cohort. The exposed group was classified into three subgroups: non-surgical, surgically treated once, and surgically treated twice or more. The mean annual net days of sick leave and disability pension combined during the ten-year follow-up was 61 days in the non-surgical group, 76 days in the surgically treated once group, and 104 days in the surgically treated twice or more subgroup. The corresponding number for the non-exposed comparison cohort was 32 days. CONCLUSION: Patients diagnosed with TMD in a hospital setting are 2-3 times more dependent on the use

BACKGROUND AND PURPOSE: High alcohol intake is associated with increased risk of postoperative complications. Alcohol cessation intervention is recommended prior to elective surgery. We investigated short- and long-term effects of perioperative intensive alcohol intervention in relation to acute ankle fracture surgery. PATIENTS AND METHODS: 70 patients requiring ankle fracture surgery and consuming ≥ 21 drinks weekly (1 drink = 12 g ethanol) were randomized to a manual-based 6-week intensive standardized alcohol cessation program, the Gold Standard Program (GSP-A), or treatment as usual (TAU), on the day of operation. GSP-A included 5 personal meetings, patient education, and motivational and pharmacological support (alcohol withdrawal prophylaxis, B vitamins, and low-dose disulfiram). Complications requiring treatment were measured after 6 weeks and 1 year. Alcohol intake was validated by biomarkers. Quality of life (QoL) was measured by the SF-36. Hospital costs were obtained from the National Hospital Costs Register. RESULTS: Postoperatively, complete alcohol cessation was higher in the GSP-A than in the TAU group (18/35 vs. 5/35, number needed to treat = 3, p ≤ 0.001), but not lowrisk consumption in the long term (10/35 vs. 7/33, p = 0.5). Number of complications in the short and long term (12/35 vs. 14/33, 16/35 vs. 18/33), the SF-36 score, or hospital costs in the short and long term (€6,294 vs. €8,024, €10,662 vs. €12,198), were similar between the groups. INTERPRETATION: Despite an effect on alcohol cessation and a positive tendency as regards the other outcomes, the postoperative complications, QoL, and costs were similar. Better perioperative strategies for acute surgical patients with high alcohol intake therefore need to be developed.

INTRODUCTION: Tobacco is still one of the single most important risk factors among the lifestyle habits that cause morbidity and mortality in humans. Furthermore, tobacco has a heavy social gradient, as the consequences are even worse among disadvantaged and vulnerable groups. To reduce tobacco-related inequity in health, those most in need should be offered the most effective tobacco cessation intervention. The aim of this study is to facilitate and improve the evaluation of already implemented national tobacco cessation efforts, focusing on 10 disadvantaged and vulnerable groups of tobacco users. METHODS AND ANALYSIS: This is a prospective cohort study. Data will be collected by established tobacco cessation counsellors in Sweden. The study includes adult tobacco or e-cigarette users, including disadvantaged and vulnerable patients, receiving in-person interventions for tobacco or e-cigarette cessation (smoking, snus and/or e-cigarettes). Patient inclusion was initiated in April 2020. For data analyses patients will be sorted into vulnerable groups based on risk factors and compared with tobacco users without the risk factor in question.The primary outcome is continuous successful quitting after 6 months, measured by self-reporting. Secondary outcomes include abstinence at the end of the treatment programme, which could be from minutes over days to weeks, 14-day point prevalence after 6 months, and patient satisfaction with the intervention. Effectiveness of successful quitting will be examined by comparing vulnerable with non-vulnerable patients using a mixed-effect logistic regression model adjusting for potential prognostic factors and known confounders. ETHICS AND DISSEMINATION: The project will follow the guidelines from the Swedish Data Protection Authority and have been approved by the Swedish Ethical Review Authority before patient inclusion (Dnr: 2019-02221). Only patients providing written informed consent will be included. Both positive and negative res

INTRODUCTION: Temporomandibular disorders (TMD) are comprised by a heterogenous group of diagnoses with multifaceted and complex etiologies. Although diseases of the musculoskeletal system and connective tissue (MSD) have been reported as risk factors for developing TMD, no nationwide population-based registry studies have been conducted to investigate this possible link. The aim of this study was to investigate the association between MSD and TMD in a population-based sample using Swedish registry data, and to further investigate the difference in such association between patients diagnosed with TMD in a hospital setting and patients surgically treated for the condition. MATERIALS AND METHODS: Population based case-control study using Swedish nationwide registry data. Data was collected between 1998 and 2016 from 33 315 incident cases and 333 122 controls aged ≥18, matched for sex, age, and living area. Cases were stratified into non-surgical (NS), surgically treated once (ST1) and surgically treated twice or more (ST2). Information on MSD exposure (ICD-10 M00-M99) was collected between 1964 and 2016. Odds ratios were calculated using conditional logistic regression, adjusted for country of birth, educational level, living area, and mental health comorbidity. RESULTS: A significant association between MSD and the development of TMD was found for all diagnostic categories: arthropathies (OR 2.0, CI 1.9-2.0); systemic connective tissue disorders (OR 2.3, CI 2.1-2.4); dorsopathies (OR 2.2, CI 2.1-2.2); soft tissue disorders (OR 2.2, CI 2.2-2.3); osteopathies and chondropathies (OR 1.7, CI 1.6-1.8); and other disorders of the musculoskeletal system and connective tissue (OR 1.9, CI 1.8-2.1). The associations were generally much stronger for TMD requiring surgical treatment. The diagnostic group with the strongest association was inflammatory polyarthropathies, M05-M14 (OR 11.7, CI 8.6-15.9), which was seen in the ST2 group. CONCLUSIONS: Patients with MSD diagnoses have

INTRODUCTION: Patients addicted to alcohol or drug often have additional unhealthy lifestyles, adding to the high mortality and morbidity in this patient group. Therefore, it is important to consider lifestyle interventions as part of the usual addiction treatment. OBJECTIVE: The aim was to identify predictors of successful changes in lifestyle risk factors among patients in treatment for alcohol or drug addiction. METHODS: We conducted a secondary analysis of a trial using a 6-week intensive integrated lifestyle intervention: The very integrated program (VIP). Patients were recruited in Addiction Centres Malmö and Psychiatry Skåne, Sweden. The primary outcome was successful changes in lifestyle, measured as quitting tobacco, exercising 30 min per day, and not being over- or underweight after 6 weeks and 12 months. RESULTS: A total of 212 patients were included in the RCT, and 128 were included in this secondary analysis: 108 at 6 weeks and 89 at 12 months of follow-up. A total of 69 patients were respondents at both follow-ups. The follow-up rates were 51 and 42%, respectively. More education, having at least 2 lifestyle risk factors and having a high quality of life were predictors of a successful change in lifestyle after 6 weeks. After 12 months, the predictors for a successful outcome were having 3 or more risk factors, while an education level up to 3 years was a negative predictor. CONCLUSIONS: Having several unhealthy lifestyles in addition to alcohol and drug addiction was a significant predictor of successful lifestyle changes in the short- and long term after the VIP for lifestyle interventions. Likewise, education was significant. The results should be considered in future development and research among this vulnerable group of patients.

Meeting adherence is an important element of compliance in treatment programmes. It is influenced by several factors one being self-efficacy. We aimed to investigate the association between self-efficacy and meeting adherence and other factors of importance for adherence among patients with alcohol and drug addiction who were undergoing an intensive lifestyle intervention. The intervention consisted of a 6-week Very Integrated Programme. High meeting adherence was defined as >75% participation. The association between self-efficacy and meeting adherence were analysed. The qualitative analyses identified themes important for the patients and were performed as text condensation. High self-efficacy was associated with high meeting adherence (ρ = 0.24, p = 0.03). In the multivariate analyses two variables were significant: avoid complications (OR: 0.51, 95% CI: 0.29-0.90) and self-efficacy (OR: 1.28, 95% CI: 1.00-1.63). Reflections on lifestyle change resulted in the themes of Health and Wellbeing, Personal Economy, Acceptance of Change, and Emotions Related to Lifestyle Change. A higher level of self-efficacy was positively associated with meeting adherence. Patients score high on avoiding complications but then adherence to the intervention drops. There was no difference in the reflections on lifestyle change between the group with high adherence and the group with low adherence.

OBJECTIVES: To investigate the association between choice of treatment and patients' income after cruciate ligament (CL) injury and assess the effect of different covariates such as sex, age, comorbidities and type of work. METHODS: This entire-population cohort study in Sweden included working patients with a diagnosed CL injury between 2002 and 2005, identified in The National Swedish Patient Register (n = 13,662). The exposure was the treatment choice (operative or non-operative treatment). The main outcome measure was average yearly income five years after CL diagnosis, adjusted for the following covariates: sex, age, comorbidities, type of work, region, calendar year, education and income. RESULTS: Relative to non-operative treatment, operative treatment was associated with greater average yearly incomes (nine to 15%) after injury among patients between 20 and 50 years, patients with partial university education, patients living in large cities and patients with one comorbidity, despite no overall significant association in the national cohort. Delayed operative treatment (>1 year) had no significant association with income change, whereas early operative treatment (<1 year) was associated with higher average yearly incomes (11 to 16%) among females, patients between 20 and 50 years, patients living in large cities and patients with one comorbidity. CONCLUSIONS: In a broad sense, treatment choice was not associated with changes in income five years after CL injuries among patients in the workforce, however earlier operative treatment was associated with higher average incomes among patients with ages between 20 and 50, females, living in large cities, with one comorbidity and with a high level of education.

BACKGROUND: Previous studies have indicated that taller individuals are at greater risk of developing cancer. Death from cancer and other specific causes have also been linked to height, but the results have been inconclusive. We aimed to shed further light on the associations between height, cancer incidence and mortality. METHODS: We conducted a nationwide, population-based prospective cohort study, including 5.5 million Swedish women and men (aged 20-74). They were followed over a period of up to 54 years. Heights were retrieved from national registers (mainly the Passport Register where heights are most often self-reported). The risks of overall and specific cancers, as well as overall and cause-specific mortality, were presented as HR with 95% CIs per 10 cm increase in height. RESULTS: A total of 278 299 cases of cancer and 139 393 cases of death were identified. For overall cancer, HR was 1.19 (1.18-1.20) in women and 1.11 (1.10-1.12) in men for every 10 cm increase in height. All 15 specific cancer types were positively associated with height-most strongly for malignant melanoma in both genders, with HRs of 1.39 (1.35-1.43) in women and 1.34 (1.30-1.38) in men. For overall mortality, HR was 0.98 (0.97-0.99) in women and 0.91 (0.90-0.92) in men for every 10 cm increase in height. Cancer mortality was increased in taller individuals, with HR 1.15 (1.13-1.17) in women and 1.05 (1.03-1.07) in men for every 10 cm increase in height, whereas shorter individuals had increased overall mortality due to a number of other causes, such as cardiovascular disease. CONCLUSION: Overall and specific cancer risks, particularly malignant melanoma, were positively associated with height. Cancer mortality also increased with height. In contrast, overall mortality was decreased with height, particularly in men due to inverse associations with height for other causes of death.

Temporomandibular joint disorders (TMJD) involve orofacial pain and functional limitations that may limit important daily activities such as chewing and speaking. This observational case-control study attempted to identify factors associated with TMJD development, particularly inflammation. The study participants were patients treated at Karolinska University Hospital, Stockholm, Sweden. The cases were patients who received a diagnosis of TMJD, chronic closed lock, or painful clicking and were treated surgically during the period from 2007 through 2011. The control group was randomly selected from among patients who had undergone tooth extraction and was matched by age and sex. A total of 146 cases and 151 controls were included in the analyses. The response rate was 55.3% for the case group and 21.8% for the control group. The male:female ratio for patients with TMJD was 1:4.4. TMJD was significantly associated with pneumonia (odds ratio [OR], 2.1), asthma (OR, 2.1), allergies (OR, 1.8), headache (OR, 3.1), general joint hypermobility (OR, 3.8), orofacial trauma (OR, 3.9), rheumatism (OR, 2.5), and orthodontic treatment (OR, 2.4) (P < 0.05 for all outcomes). In conclusion, autoimmune diseases and inflammatory conditions are associated with increased risk of TMJD. Moreover, certain lung disorders may predict subsequent development of TMJD.
