Influence of stress resilience in adolescence on long-term risk of psoriasis and psoriatic arthritis among men: A prospective register-based cohort study in Sweden.

BACKGROUND: Although stress is considered to be a negative factor for psoriasis, no convincing scientific evidence of this association exists, largely because of difficulties in measuring stress. Stress resilience is the ability to cope with and adapt to stressful events. Stress resilience can be measured in a standardized way and used as a marker for chronic stress. OBJECTIVES: The objective of this study is to investigate whether low stress resilience in adolescence increases the risk for onset of psoriasis and psoriatic arthritis later in life. METHODS: A cohort of Swedish men (mean age 18.3 years), enrolled in compulsory military service between 1968 and 2005, was created using data from the Swedish Military Service Conscription Register (n = 1,669,422). Stress resilience at conscription was estimated using standardized semi-structured interviews, and was divided into three categories: low, medium and high. The men were followed from conscription until new-onset psoriasis or psoriatic arthritis, death or emigration or at the latest until 31 December 2019. Cox regression models adjusted for confounders at conscription were used to obtain hazard ratios (HRs) with 95% confidence intervals (CIs) for incident psoriasis and psoriatic arthritis. RESULTS: Men in the lowest stress resilience category had an increased risk of psoriasis and psoriatic arthritis (HR 1.31 (95% CI 1.26-1.36) and 1.23 (95% CI 1.15-1.32), respectively), compared with those in the highest stress resilience category. When including only hospitalized patients the HRs for psoriasis and psoriatic arthritis in the lowest stress resilience group were 1.79 (1.63-1.98) and 1.53 (1.32-1.77), respectively. CONCLUSIONS: This large, prospective register study suggests that low stress resilience in adolescence is associated with an increased risk of incident psoriasis among men. The results indicate that patients with psoriasis have an inherent psychological vulnerability, and highlight the importance of addressing psychological well-being in the management of psoriasis.

Surgery to relieve nasal obstruction: outcome for 366 patients operated on by one senior surgeon.

BACKGROUND: Studies of patient-rated outcome in septoplasty and turbinoplasty most frequently involve several surgeons with varying surgical skills, techniques and experience. The aim of the present study was to evaluate outcome based on one experienced surgeon. METHODS: Three hundred and sixty-six consecutive patients referred for nasal obstruction were included. All the patients were examined with nasal endoscopy before and after decongestion, they filled out a nose VAS and rated their overall general health before and three to six months after surgery. The patients underwent septoplasty, septoplasty plus turbinoplasty or turbinoplasty. RESULTS: The mean nose VAS for nasal obstruction (0-100) preoperatively was 64.7 for all patients. Patients undergoing septoplasty (n = 159) were younger than patients undergoing septoplasty + turbinoplasty (n = 79) or patients undergoing turbinoplasty alone (n = 128). The nose VAS for nasal obstruction improved significantly in all three groups and 25% had a normal nose VAS after surgery in the septoplasty and septoplasty + turbinoplasty groups compared to only 8% in the turbinoplasty alone group. There was no significant difference in the improvement in nasal obstruction between septoplasty and septoplasty + turbinoplasty, but the septoplasty + turbinoplasty group experienced a significantly greater improvement in general health. CONCLUSIONS: In 366 patients operated on by one experienced surgeon, septoplasty and septoplasty + turbinoplasty were more effective at relieving nasal obstruction than turbinoplasty alone. Septoplasty + turbinoplasty resulted in a greater improvement in general health than septoplasty alone, despite the same improvement in nasal obstruction, indicating a beneficial effect of additional turbinoplasty in septoplasty.

Prognostic factors for outcome after septoplasty in 888 patients from the Swedish National Septoplasty Register.

BACKGROUND: The aim of this study was to identify predictors of outcome after septoplasty in 888 patients from the Swedish National Septoplasty Register. METHODOLOGY: This is an observational register study analysing data from patients undergoing septoplasty in Sweden between 2015 and 2016. The patients reported severity of nasal obstruction (mild, moderate, severe) pre- and again 12 months postoperatively (none, mild, moderate, severe), unplanned visits within 30 days after surgery. The examining doctor reported co-morbidities such as allergic rhinitis and snoring. The primary end-point was one level improvement of the nasal obstruction 12 months after surgery. RESULTS: Nasal obstruction had improved in 63% 12 months after surgery. Twelve months after surgery, 81% with severe nasal obstruction and 31% with mild nasal obstruction before surgery had improved. Only 56% reported that the results of the surgery were as they had expected. Higher patient age at surgery, no unplanned visits within 1 month of surgery and activity limitation before surgery were associated with improvements in nasal breathing in the logistic regression model. CONCLUSION: Septoplasty should be offered to patients with severe nasal obstruction and surgery should be avoided in mild nasal obstruction confirmed by both an improvement in nasal obstruction and patient expectations in this study.

Who experiences higher and increasing breathlessness in advanced cancer? The longitudinal EPCCS Study.

PURPOSE: Breathlessness is a major cause of suffering in advanced cancer. We aimed to determine the symptom trajectory in people with advanced cancer and to identify those at increased risk of experiencing higher or increasing breathlessness over time in advanced cancer. PATIENTS AND METHODS: This was an analysis of the multinational, prospective, longitudinal European Palliative Care Cancer Symptom (EPCCS) study. We included adults with confirmed incurable cancer enrolled in palliative care, with prospective monthly assessments for up to 6 months, withdrawal or death, whichever came first. Symptom severity (0-10 numerical rating scales) was analyzed using multivariate random coefficients regression. RESULTS: A total of 1689 patients (50 % women; mean age 65.7 ± [standard deviation; SD] 12.4 years) were included. Main diagnoses were digestive (31 %), lung (20 %), and breast (17 %) cancers. During a median follow-up of 62 (interquartile range, 0 to 133) days, 65 % were breathless at some point and 36 % of all patients reported moderate/severe breathlessness. The group mean (1.6 points; SD, 2.4) was unchanged over time, but the severity varied markedly between patients and over time. Independent predictors for worse breathlessness were COPD, lung cancer, living alone, lung metastases, anxiety, pain, depression, and lower performance status. Predictors of worsening breathlessness over time were low performance status (p = 0.039) and moderate to severe pain (p = 0.012). CONCLUSION: In the largest longitudinal clinical study to date in advanced cancer alone, breathlessness was frequent and associated with factors including respiratory disease, other concurrent unpleasant symptoms, and impaired performance status. Increase in severity over time was predicted by performance status and pain.

Nocturnal GERD - a risk factor for rhinitis/rhinosinusitis: the RHINE study.

BACKGROUND: It has been suggested that gastroesophageal reflux disease (GERD) is a risk factor for developing rhinitis/rhinosinusitis, but data are lacking. This is a prospective 10-year follow-up study of a large multicenter cohort from Northern Europe, evaluating the relationship between nocturnal GERD and noninfectious rhinitis (NIR). METHODS: The study comprised 5417 subjects born between 1945 and 1973, who answered a questionnaire in 1999-2001 and again in 2010-2012. Noninfectious rhinitis was defined as having nasal obstruction, secretion, and/or sneezing without having the common cold. Odds ratios for developing NIR in relation to age, gender, BMI, smoking, asthma, and nocturnal GERD were calculated. RESULTS: During the 10-year observation period, 1034 subjects (19.1%) developed NIR. Subjects reporting nocturnal gastroesophageal reflux in both 1999 and 2010 had more NIR in 2010 (2.8% vs 1.2%, P < 0.001). There was a significant dose-response relationship between the number of reflux episodes/week in 1999 and the risk of having NIR in 2010, P = 0.02. In the multiple regression adjusted for age, gender, BMI, tobacco smoke, and asthma, those with nocturnal GERD in 1999 (≥3 episodes of nocturnal gastroesophageal reflux symptoms per week) had an OR of 1.6 (95% CI 1.0-2.5, P = 0.03) to develop NIR in 2010. Smoking was associated both with an increased risk of developing NIR (30.7% vs 24.0%, P < 0.001) and with the development of nocturnal GERD. CONCLUSION: This large, population-based, 10-year study indicates that nocturnal GERD was a risk factor for noninfectious rhinitis/rhinosinusitis. GERD should therefore be considered in patients with rhinitis of known and unknown origin.

Antihypertensive treatment and control according to gender, education, country of birth and psychiatric disorder: the Swedish Primary Care Cardiovascular Database (SPCCD).

The reasons why women and men are treated with different antihypertensive drugs are not clear. Whether socioeconomic factors influence prescription patterns and blood pressure control differently in women and men has not been investigated. This cross-sectional study performed in a cohort of hypertensive patients from the Swedish Primary Care Cardiovascular Database (SPCCD) examined the influence of educational level, country of birth, gender and concomitant psychiatric disorder on prescription pattern and blood pressure control in 40,825 hypertensive patients. Men were more often than women treated with calcium channel blocker and angiotensin-converting enzyme inhibitor (ACEI), irrespective of education, country of birth and psychiatric disorder. Educational level influenced the prescription pattern to some extent, where the gender differences were reduced in patients with a higher educational level. In women, but not in men, high educational level and concomitant psychiatric disorder were associated with a higher proportion reaching target blood pressure. The predominant use of ACEI and calcium channel blockers in men is not influenced by educational level, country of birth or psychiatric disorder. Thus other explanations must be considered such as gender differences in side effects. Educational level seems to have a greater impact on reaching target blood pressure in women compared with men.

Influence of refill adherence method when comparing level of adherence for different dosing regimens.

PURPOSE: To examine the impact of two methods when estimating refill adherence in patients using bisphosphonates with different dosing regimens. METHODS: In the Swedish Prescribed Drug Register, 18,203 new users of bisphosphonates aged 18-85 years were identified between 1 July 2006 and 30 June 2007 and followed for a maximum of 2 years. The patients were categorised based on dosing regimen: one tablet daily, one tablet weekly, switching between these regimens, and other regimens. Refill adherence was estimated with Continuous measure of Medication Acquisition (CMA, adherent if CMA ≥ 80 %) and the maximum gap method (adherent if gaps <45 days). Differences in adherence between patients in the groups were assessed with logistic regression models controlling for confounding factors. RESULTS: The proportion of patients classified as adherent was higher using CMA compared with patients classified as adherent using the maximum gap method. Patients on one tablet weekly had significantly lower adherence compared with patients on one tablet daily in the main analyses of both methods (the maximum gap method: 73 % vs. 80 %; adjusted OR=0.71; 95 % CI 0.57-0.89 and CMA: 84 % vs. 88 %, adjusted OR=0.75; 95 % CI 0.57-0.99). Patients using the other two dosing regimens had significantly lower adherence compared with patients on one tablet daily using both methods. CONCLUSION: Choice of method has an impact on the estimates of refill adherence to bisphosphonates. Patients on one tablet weekly dosing had lower adherence compared with patients on one tablet daily dosing using both methods.

Robust outbreak surveillance of epidemics in Sweden.

Outbreak detection is of interest in connection with several diseases and syndromes. The aim is to detect the progressive increase in the incidence as soon as possible after the onset of the outbreak. A semiparametric method is applied to Swedish data on tularaemia and influenza. The method is constructed to detect a change from a constant level to a monotonically increasing incidence. If seasonal effects are present, the residuals from a model incorporating these can be used. The properties of the method are evaluated by application to Swedish data on tularaemia and influenza and by simulations. The suggested method is compared with subjective judgments as well as with other algorithms. The conclusion is that the method works well. A user-friendly computer program is described.
