- The large amount of glucose in the dialysate used in peritoneal dialysis (PD) likely affects the glycemic control. The aim of this study was to investigate the association between HbA1c variability, as a measure of long-term glycemic variability, and the risk of all-cause mortality in diabetic patients with PD.325 patients with diabetes and ESRD were followed (2008-2018) in the Swedish Renal Registry. Patients were separated in seven groups according to level of HbA1c variability. The group with the lowest variability was denoted the reference. The ratio of the standard deviation (SD) to the mean of HbA1c, HbA1c (SD)/HbA1c (mean), i.e. the coefficient of variation (CV), was defined as HbA1c variability. Hazard ratios (HR) and 95% confidence intervals (CI) were examined using Cox regression analyses.During follow-up, 170 (52%) deaths occurred. The highest mortality was among patients with the second highest HbA1c variability, CV≥2.83 [n = 44 of which 68% patients died]. In the multivariate analyses where lowest HbA1c variability (CV≤0.51) was used as the reference group, HbA1c CV 2.83-4.60 (HR 3.15, 95% CI 1.78-5.55; p<0.001) and CV> 4.6 (HR 2.48, 95% CI 1.21-5.11; p = 0.014) were associated with increased risk of death.The high risk of all-cause mortality in patients with diabetes and PD increased significantly with elevated HbA1c variability, as measure of long-term glycemic control. This indicates that stable glycemia is associated with an improvement of survival; whereas more severe glycemic fluctuations, possibly caused by radical changes in dialysis regimes or peritonitis, are associated with a higher risk of mortality in diabetic patients with PD.

- Knowledge about association between glycated hemoglobin (HbA1c) and risk of all-cause mortality in patients with diabetes mellitus on maintenance hemodialysis (HD)-treatment is sparse. The study aims to investigate association between HbA1c and all-cause mortality in patients with diabetes and maintenance HD-treatment, separately for two age groups- above and below 75years.2487 patients (mean age 66years, 66% men) were separated in two age groups: ≤75years (n=1810) and>75years (n=677) and followed up between 2008 and 2018. Hazard ratios (HR) and 95% confidence intervals (CI) for associations between HbA1c and all-cause mortality were calculated using Cox-regression-models.1295 (52%) patients died and 473 (70%) among the patients above 75years old. In the multivariate analysis, HbA1c5-6% was used as reference. In patients≤75years old, only increased HbA1c>9.7%, HR2.03(CI1.43-2.89) was associated with increased risk of all-cause mortality. In patients>75years, HbA1c≤5%, HR1.67(CI1.16-2.40); HbA1c6.9-7.8%, HR1.41(CI1.03-1.93) and HbA1c8.7-9.7%, HR1.79 (CI1.08-2.96) were associated with increased risk of all-cause mortality.We found a J-shaped association between HbA1c and mortality only in diabetic HD-patients>75years. This probably indicates that in an old population of diabetic HD-patients, both intensive glucose control and hyperglycemia could be harmful and associated with higher risk of death.

- Introduction Obesity is a rapidly growing global health concern with considerable negative impact on life-time expectancy. It has yet not been clarified if and how obesity impacts outcomes of severe bacterial infections. The aim of this study was to determine how body mass index impacts outcome of severe bacterial infections in a well-defined population-based cohort. Methods This study is based on a cohort of 2196 patients included in a Swedish prospective, population-based, consecutive observational study of the incidence of community-onset severe sepsis and septic shock in adults. All patients with weight and height documented in the medical records on admission were included. Results The case fatality rate (CFR) was negatively correlating with increasing BMI. Outcomes included 28-day CFR (p-value = 0.002), hospital CFR (p-value = 0.039) and 1-year CFR (p-value<0.001). When BMI was applied as continuous variable in a multiple logistic regression together with other possible covariates, we still could discern that BMI was associated with decreasing 28-day CFR (OR = 0.93, 95% CI 0.88-0.98, p-value = 0.009) and 1-year CFR (OR = 0.94, 95% CI 0.91-0.97, p-value<0.001). Conclusion The hypothesis and paradox of obesity being associated with higher survival rates in severe bacterial infections was confirmed in this prospective, population-based observational study.

- BACKGROUND: In order to treat pain optimally, the Emergency Medical Service (EMS) clinician needs to be able to make a reasonable estimation of the severity of the pain. It is hypothesised that various physiological parameters will change as a response to pain.AIM: In a cohort of patients who were seen by EMS clinicians, to relate the patients' estimated intensity of pain to various physiological parameters.METHODS: Patients who called for EMS due to pain in a part of western Sweden were included. The intensity of pain was assessed according to the visual analogue scale (VAS) or the Numerical Rating Scale (NRS). The following were assessed the same time as pain on EMS arrival: heart rate, systolic and diastolic blood pressure, respiratory rate, moist skin and paleness.RESULTS: In all, 19,908 patients (≥18 years), were studied (51% women). There were significant associations between intensity of pain and the respiratory rate (r = 0.198; p < 0.0001), heart rate (r = 0.037; p < 0.0001), systolic blood pressure (r = -0.029; p < 0.0001), moist skin (r = 0.143; p < 0.0001) and paleness (r = 0.171; p < 0.0001). The strongest association was found with respiratory rate among patients aged 18-64 years (r = 0.258; p < 0.0001).CONCLUSION: In the prehospital setting, there were significant but weak correlations between intensity of pain and physiological parameters. The most clinically relevant association was found with an increased respiratory rate and presence of pale and moist skin among patients aged < 65 years. Among younger patients, respiratory rate may support in the clinical evaluation of pain.

- Background: Nasal polyps is a common disease but little is known about its' pathogenesis. Our hypothesis was that there are genetic factors involved in the development of this disease. The aim of this study was to examine close relatives of patients with nasal polyps and comparing them with a general population with regard to prevalence of polyps. Methodology: Patients with nasal polyps who attended the clinic were recruited to the study and were asked whether they had any close adult relatives (siblings, parents or children). We intended to recruit two relatives per patient, one of each gender, for nasal endoscopy. The prevalence of nasal polyps in these relatives was compared with the prevalence of nasal polyps in a general population. Results: During a 4-year period, 368 patients and 410 relatives were recruited to the study. Although we were unable to recruit two close relatives for every patient, we were able to calculate nasal polyp prevalence within families as being 19.2%. Compared with the prevalence of nasal polyps among individuals in a general Swedish population from the same geographical area, the relative risk for polyps among relatives was almost five times higher. Conclusion: This study strongly indicates that heredity is a factor of importance for development of nasal polyps.

- Objectives: The aim of this study was to investigate the relative frequency of important symptoms of chronic rhinosinusitis with nasal polyps (CRSwNP), the link between CRSwNP and the lower airways and the importance of smoking in CRSwNP.Method: Three hundred and sixty-eight patients with CRSwNP and 1349 controls were recruited to the study and underwent a structured interview about symptoms from the upper and lower airways, and about smoking habits. Furthermore, all participants were clinically examined using nasal endoscopy.Results: Due to interactions between the outcome variables, a multiple logistic regression model was fitted to the data. Nasal secretions, nasal blockage and impaired sense of smell were symptoms associated with CRSwNP. Furthermore, male gender, increasing age and asthma were also associated with the disease. Current smoking was less frequent among patients with CRSwNP.Conclusion: By comparing symptoms and risk factors of patients with CRSwNP with those of a large population-based control group and testing them in a multiple logistic regression model, we have been able to generate data that address key research interests in CRSwNP.

- PurposeThe aim was to prospectively map symptom clusters in patients with stage I–IIIa breast cancer during standard chemotherapy treatment in a randomised study.MethodsParticipants completed the Memorial Symptom Assessment Scale (MSAS) at baseline, day 12 after the first and third cycle of FEC 75 or FEC 100, and day 12 after the last cycle of Taxotere. Cut-off values for symptom scores, a mean value based on each individual reporting a symptom including occurrence, frequency, severity and distress for inclusion in analysis, were determined.ResultsThe symptom burden cluster analysis was conducted in two steps and included symptoms with high frequency and high levels of distress. The factor analysis revealed three symptom clusters; physical, gastro (phys/gastro) and emotional, with core symptoms that remained stable over time. The most prevalent symptoms for the total sample during all cycles were as follows: lack of energy (range between 48 and 90%), feeling sad (48–79%), difficulty sleeping (54–78%), difficulty concentrating (53–74%), worrying (54–74%) and pain (29–67%).ConclusionIn summary, we have prospectively established that symptom clusters remain stable over time with a basis of core symptoms. This knowledge will aid in the development of effective core symptom-focused interventions to minimise symptom burden for patients treated with chemotherapy for breast cancer.
