- Introduction: Breathlessness is common in the population, especially in women and associated with adverse health outcomes. Obesity (body mass index (BMI) >30 kg/m(2)) is rapidly increasing globally and its impact on breathlessness is unclear.Methods: This population-based study aimed primarily to evaluate the association of current BMI and self-reported change in BMI since age 20 with breathlessness (modified Research Council score >= 1) in the middle-aged population. Secondary aims were to evaluate factors that contribute to breathlessness in obesity, including the interaction with spirometric lung volume and sex.Results: We included 13 437 individuals; mean age 57.5 years; 52.5% women; mean BMI 26.8 (SD 4.3); mean BMI increase since age 20 was 5.0 kg/m(2); and 1283 (9.6%) reported breathlessness. Obesity was strongly associated with increased breathlessness, OR 3.54 (95% CI, 3.03 to 4.13) independent of age, sex, smoking, airflow obstruction, exercise level and the presence of comorbidities. The association between BMI and breathlessness was modified by lung volume; the increase in breathlessness prevalence with higher BMI was steeper for individuals with lower forced vital capacity (FVC). The higher breathlessness prevalence in obese women than men (27.4% vs 12.5%; p<0.001) was related to their lower FVC. Irrespective of current BMI and confounders, individuals who had increased in BMI since age 20 had more breathlessness.Conclusion: Breathlessness is independently associated with obesity and with weight gain in adult life, and the association is stronger for individuals with lower lung volumes.

- Objective: To assess the incidence of groin hernia repair after radical prostatectomy for prostate cancer compared with the incidence in a control population without prostate cancer in a nationwide, population-based study.Background: Recent reports indicate an increase in the incidence of groin hernia repair after radical prostatectomy. Inadequate knowledge of the incidence of groin hernia in the general population makes this information hard to interpret.Methods: Information was retrieved from the Prostate Cancer Database (PCBaSe) and Swedish Hernia Register for events between 1998 and 2010. The incidence of groin hernia surgery was calculated for a group of men treated with radical prostatectomy (open and minimally invasive) and for a group treated with radiation therapy, and these were compared with the incidence in a control cohort of men matched for age and county of residence. Multivariate analysis was used to assess the hazard ratio (HR) of groin hernia repair according to age, tumor risk category, and Charlson Comorbidity Index.Results: A total of 28,608 cases and 105,422 controls were included in the study. Men treated with radical prostatectomy and radiation therapy had a significantly higher incidence of groin hernia repair than the control cohort: HR: 3.95 (95% confidence interval: 3.70-4.21) for retropubic prostatectomy, HR: 3.37 (95% confidence interval: 2.95-3.87) for minimally invasive prostatectomy, and HR: 1.84 (95% confidence interval: 1.66-2.04) for radiation therapy.Conclusions: An almost 4-fold increase in groin hernia repair was observed after radical prostatectomy compared with controls, and men who received radiation therapy had an almost 2-fold increase in incidence. As well as postoperative changes in the abdominal wall, increased vigilance for groin hernia seems to be important for the increased incidence of groin hernia repair seen after radical prostatectomy or radiation therapy for prostate cancer.

- BACKGROUND: Emergency hernia surgery, in contrast to elective hernia surgery, is associated with appreciable mortality. Incarcerated hernia is the second most common cause of small bowel obstruction after adhesions, and the leading cause of bowel strangulation.METHODS: Information on patients who died within 30 days of groin hernia surgery was retrieved from the Swedish Hernia Register, from the Cause-of-Death Register, and from hospital notes.RESULTS: Of 103,710 groin hernia operations between 1992 and 2004, 292 patients died within 30 days of surgery. Hospital notes and cause of death were retrieved for 242 cases (82%). In 5 of these patients, the hernia operation was done in addition to more urgent surgery and therefore excluded from further analyses; 152 patients were admitted as emergency cases and 55 of these patients underwent bowel resection. A total of 107 patients had signs of bowel obstruction when admitted. For 37% of these patients, physical examination of the groin was not documented. Patients with bowel obstruction without a note on a palpable groin lump were more likely to undergo imaging investigation preoperatively (P < 0.001) and they had an increased time to surgery compared to patients with a palpable lump. Women and patients with femoral hernia were significantly less likely to undergo a groin examination compared to other patients. Local anaesthesia was used in 7% of all patients who died postoperatively, and in 3% of emergency cases. Pulmonary disease, sepsis and malignant disease were more common as causes of death after emergency surgery than after elective surgery.CONCLUSIONS: Groin examination of patients presenting with bowel obstruction is of utmost importance in order to minimise delay to hernia surgery.

- Objective: To analyze mortality following groin hernia operations.Summary Background Data: It is well known that the incidence of groin hernia in men exceeds the incidence in women by a factor of 10. However, gender differences in mortality following groin hernia surgery have not been explored in detail.Methods: The study comprises all patients 15 years or older who underwent groin hernia repair between January 1, 1992 and December 31, 2005 at units participating in the Swedish Hernia Register (SHR). Postoperative mortality was defined as standardized mortality ratio (SMR) within 30 days, ie, observed deaths of operated patients over expected deaths considering age and gender of the population in Sweden.Results: A total of 107,838 groin hernia repairs (103,710 operations), were recorded prospectively. Of 104,911 inguinal hernias, 5280 (5.1%) were treated emergently, as compared with 1068 (36.5%) of 2927 femoral hernias. Femoral hernia operations comprised 1.1% of groin hernia operations on men and 22.4% of operations on women. After femoral hernia operation, the mortality risk was increased 7-fold for both men and women. Mortality risk was not raised above that of the background population for elective groin hernia repair, but it was increased 7-fold after emergency operations and 20-fold if bowel resection was undertaken. Overall SMR was 1.4 (95% confidence interval, 1.2-1.6) for men and 4.2 (95% confidence interval, 3.2-5.4) for women, in accordance with a greater proportion of emergency operations among women compared with men, 17.0%, versus 5.1%.Conclusions: Mortality risk following elective hernia repair is low, even at high age. An emergency operation for groin hernia carries a substantial mortality risk. After groin hernia repair, women have a higher mortality risk than men due to a greater risk for emergency procedure irrespective of hernia anatomy and a greater proportion of femoral hernia.

- Aims and objectives: To explore municipal healthcare employees' experiences of relationships with care recipients and colleagues. The specific research questions were when do the relationships enhance well-being, and what prerequisites are needed for such relationships to occur? Background: Employees in health and social care for older people often depict their work in negative terms, and they often take a high number of sick leaves. Despite the heavy workload, other employees express well-being at work and highlight social relationships as one reason for this. However, a greater understanding of how these relationships can act as resources for workplace well-being is needed. Design: The design of the study was qualitative and exploratory. Methods: Qualitative interview studies were conducted with 23 healthcare employees in municipal health care. Thematic analysis was used to analyse the data. Results: Two themes were identified as resources for promoting relationships between employees and care recipients or colleagues: (a) Being personal-a close interpersonal relationship to a care recipient-and (b) Colleague belongingness-a sense of togetherness within the working group. Spending quality time together, providing long-term care and providing additional care were prerequisites for a close interpersonal relationship with care recipients. Trust, mutual responsibility and cooperation were prerequisites for a sense of togetherness within the working group. Conclusions: The findings provide an empirical base to raise awareness of relationships with care recipients and colleagues as health aspects. Relationships among employees in health care are vital resources that must be considered to create sustainable workplaces and consequently improve the quality of care. Relevance to clinical practice: The results of this study advocate health promotion efforts based on interpersonal relationships at the workplace. Dialogues in the working groups, based on the employees' experiences of positive daily situations, may be a promoting method for the work-related well-being of the employees.

- BACKGROUND: Radiofrequency ablation (RFA) and laparoscopic partial nephrectomy (LPN) are used to treat small renal masses (SRM; ≤4 cm), although there are conflicting results in the changes in creatinine and estimated glomerular filtration rate (eGFR) after treatment. On contrast-enhanced computed tomography (CE-CT) images, the quantity and quality of renal function can be evaluated by calculating the split renal function (SRF).PURPOSE: To compare renal function after RFA or LPN treatment of SRMs through evaluation of the SRF in the affected kidney.MATERIAL AND METHODS: Single T1a renal tumors successfully treated with RFA (n = 60) or LPN (n = 31) were retrospectively compared. The SRF was calculated on pre-treatment CE-CT images and the first follow-up exam after completed treatment. Serum creatinine and eGFR values were collected simultaneously. To compare renal function outcomes, Student's t-test and multivariable linear regression models (adjusted to RFA/LPN treatment, pre-treatment SRF/eGFR, BMI, age, tumor characteristics, and Charlson Comorbidity Index) were used.RESULTS: SRF was reduced in both groups, although reduction was greater in the LPN group (LPN -5.7%) than in the RFA group (RFA -3.5%; P = 0.013). After adjusted analysis, the LPN group still had greater SRF reduction (difference 3.2%, 95% confidence interval 1.3-1.5; P = 0.001). There was no difference between groups in the change of creatinine/eGFR after treatment.CONCLUSION: Both RFA and LPN are nephron-sparing when treating SRMs. However, in this series, reduction of SRF in the affected kidney was smaller after RFA, having a more favorable preservation of renal function than LPN.

- The performance of the Hartree-Fock method and the three density functionals B3LYP, PBE0, and CAM-B3LYP is compared to results based on the coupled cluster singles and doubles model in predictions of the solvatochromic effects on the vertical n-->pi(*) and pi-->pi(*) electronic excitation energies of acrolein. All electronic structure methods employed the same solvent model, which is based on the combined quantum mechanics/molecular mechanics approach together with a dynamical averaging scheme. In addition to the predicted solvatochromic effects, we have also performed spectroscopic UV measurements of acrolein in vapor phase and aqueous solution. The gas-to-aqueous solution shift of the n-->pi(*) excitation energy is well reproduced by using all density functional methods considered. However, the B3LYP and PBE0 functionals completely fail to describe the pi-->pi(*) electronic transition in solution, whereas the recent CAM-B3LYP functional performs well also in this case. The pi-->pi(*) excitation energy of acrolein in water solution is found to be very dependent on intermolecular induction and nonelectrostatic interactions. The computed excitation energies of acrolein in vacuum and solution compare well to experimental data.
