- 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: Data on compliance to adjuvant endocrine treatment (ET) is mainly reported from prospective clinical trials or from smaller retrospective cohorts without correlation to outcome. Aims: To determine compliance to adjuvant ET and the impact on survival in a population-based series of patients with early breast cancer (BC) advised ET. Patients and methods: 1090 consecutive patients with hormone receptor positive (HR+) stage I-III BC diagnosed from 1 January 1997 to 31 December 2003 from one health care region of Sweden were included. Data on tumour, type of ET, compliance, reason for termination and outcome were collected. Statistical analyses were calculated with patients in three groups. Results: 72 patients were excluded leaving 1018 patients with a HR+ stage I to III BC for analyses. The most common ET was tamoxifen (n = 751, 73.8%). At the last follow up (31 Dec 2019) with a median follow-up of 18 years (interquartile range 16–22) 228 (22.4%) patients had a relapse. 71.1% of the included patients were compliant to endocrine therapy. Older patients ≥74 years had lower compliance, 61% compared with 75% in the other age groups (≤50 years and 51–73 years) (p < 0001), other parameters including type of ET were not associated with compliance. Low compliance remained as an independent risk factor in multivariate analyses for lower relapse-free survival, HR=1.83, 95% Confidence Interval (CI) 1.52–2.19, p < 0.001 and for time to BC death, HR=2.69, 95%CI 1.82–3.98, p < 0.001. Conclusions: Patients compliant to adjuvant ET have an improved survival.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: Our purpose was to investigate the association between family history of renal cell carcinoma (RCC) and RCC risk. MATERIALS AND METHODS: RCC cases diagnosed in Sweden between 2005 and 2014 and 10 matched controls were identified using the Renal Cell Cancer Database Sweden, with linkage to the Multigeneration Register and the Swedish Cancer Registry. The association between a family history of RCC and RCC was investigated, overall and by sex and age groups. RESULTS: Among 9416 RCC cases, 294 (3.1%) had 1 or more parent or sibling (first-degree relative [FDR]) with RCC. Median age at diagnosis for cases with an affected FDR was 65 years (IQR 59-71) and 68 years (IQR 60-75) for all cases. The proportion of women was significantly higher among familial RCC compared to sporadic RCC (44.6% vs 38.5%, P = .035). RCC was twice as likely with 1 or more FDR with RCC (OR 1.9; CI 1.65-2.16). Stratified analysis showed an OR of 2.4 for women (CI 1.93-2.92) and 1.6 for men (CI 1.35-1.93). Two or more FDRs was associated with a sixfold increased risk (95% CI 2.37-15.5). Familial RCC was strongly associated with bilateral and multifocal tumors (OR 5.5; CI 2.36-13.0, OR 3.5; CI 1.89-6.49). CONCLUSIONS: In this Swedish data set, 3.1% of RCC patients have 1 or more FDR diagnosed with RCC. There was no statistical difference in median age between sporadic RCC and familial RCC. Having 1 or more FDR with RCC approximately doubles the risk of RCC with a higher risk increase for women than for men. People with 2 FDRs with RCC constitute a small high-risk group that may benefit from screening.

Clinical evaluation of molecular surrogate subtypes in patients with ipsilateral multifocal primary breast cancer
- 2023

Ingår i: Breast Cancer Research. - 1465-5411. ; 25:1

Tidskriftsartikel (refereegranskat)abstract
- BackgroundWhen ipsilateral multifocal primary breast cancer (IMBC) is detected, standard routine is to evaluate the largest tumor with immunohistochemistry (IHC). As all foci are not routinely characterized, many patients may not receive optimal adjuvant treatment. Here, we assess the clinical relevance of examining at least two foci present in patients with IMBC.MethodsPatients diagnosed and treated for IMBC at Sahlgrenska University Hospital (Gothenburg, Sweden) between 2012 and 2017 were screened. In total, 180 patients with >= 2 invasive foci (183 specimens) were assessed with IHC and included in this study. Expression of the estrogen (ER) and progesterone (PR) receptors, Ki67, HER2, and tumor grade were used to determine the molecular surrogate subtypes and discordance among the foci was recorded. An additional multidisciplinary team board was then held to re-assess whether treatment recommendations changed due to discordances in molecular surrogate subtype between the different foci.ResultsDiscordance in ER, PR, HER2, and Ki67 was found in 2.7%, 19.1%, 7.7%, and 16.9% of invasive foci, respectively. Discordance in the molecular surrogate subtypes was found in 48 of 180 (26.7%) patients, which resulted in therapy changes for 11 patients (6.1%). These patients received additional endocrine therapy (n = 2), chemotherapy (n = 3), and combined chemotherapy and trastuzumab (n = 6).ConclusionTaken together, when assessing at least two tumor foci with IHC, regardless of shared morphology or tumor grade between the different foci, 6.1% of patients with IMBC were recommended additional adjuvant treatment. A pathologic assessment using IHC of all foci is therefore recommended to assist in individualized treatment decision making.

- Background Delirium is common in older hospitalized patients. It has serious consequences e.g., poor health outcomes, mortality and increased costs. Despite that, many cases are undetected. Early detection of delirium is important in improving outcomes and use of assessment tools improves detection rates. The 4AT is a brief screening tool for delirium detection, which has not previously been translated into Swedish. The study aim was to evaluate diagnostic accuracy and clinical applicability of a Swedish version of the screening tool 4AT for delirium detection. Method This diagnostic test accuracy study used a quantitative and a qualitative approach and evaluated the patients' and the health care professionals' experiences of the tool. Study included 200 patients >= 65 years from a university hospital and a county hospital in two Swedish regions. Medical specialties were geriatric stroke/neurology, geriatric multimorbidity, severe cognitive impairment, orthopaedic, and urology. The translated 4AT was tested against the reference standard DSM-IV-TR criteria, based on the Organic Brain Syndrome scale and patient records. The 4AT was assessed simultaneously and independently by two assessors. Additionally, data was collected through patient record reviews, and questions about applicability to the patients (n = 200) and the assessors (n = 37). Statistical analyses, and qualitative content analyses were conducted. Results By reference standard 18% had delirium, and by 4AT 19%. The overall percent agreement was 88%, AUROC 0.808, sensitivity 0.70 (95% CI 0.51-0.84) and specificity 0.92 (95% CI 0.87-0.96). In the ward for severe cognitive impairment (n = 63) the 4AT was less sensitive and less specific. In the other wards (n = 132) sensitivity was 0.77 (95% CI 0.50-0.93), specificity 0.93 (95% CI 0.87-0.97), and AUROC 0.848. Interrater reliability (Kappa) was 0.918, p = < 0.001 (n = 144). The 4AT was well tolerated by patients, easy to use for health care professionals, and took a few minutes to conduct. Conclusion The Swedish version of 4AT is an accurate and applicable tool to use in clinical practice for detecting delirium in hospitalized patients across different medical specialities, and to use by different professionals and levels of seniority. To improve patient outcomes, we recommend the 4AT to be incorporated in clinical practice in health care settings in Sweden.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: The Quantified behavior Test (QbTest), which combines a continuous performance task (CPT) and motion tracking, provides data for the core signs of attention-deficit/hyperactivity disorder (ADHD): attention, hyperactivity, and impulsivity. This study aimed to evaluate the performance of children and adolescents with ADHD on the QbTest before and after a single methylphenidate (MPH) dose. Subjects and Methods: This retrospective chart review study included data from 149 children and 215 adolescents who completed the QbTest. A summary index of the CPT and motion capture data on the QbTest is provided by three cardinal parameters: QbActivity, QbImpulsivity, and QbInattention. The test was performed twice on the same day, before and up to three hours after MPH intake. A decrease by ≥ 0.5 in a cardinal parameter score was considered an improvement, whereas an increase by ≥ 0.5 a deterioration. Results: QbActivity improvement after MPH intake was present in 71.7% and 76.2% of the children and adolescents, respectively. QbImpulsivity improvement was observed in 50.4% of the children and 44.7% of the adolescents, and QbInattention improvement in 85.1% and 91.1% of the children and adolescents, respectively. All three parameters improved simultaneously in 27.7% of the children and 28.7% of the adolescents. The likelihood that one parameter deteriorated after MPH use was greater if that parameter was within the normal range before medication. This was most pronounced for QbImpulsivity. Among male adolescents, QbInattention improvement was often accompanied by QbImpulsivity deterioration. Conclusion: The QbTest inattention and motor activity parameters improved markedly after a single MPH dose in children and adolescents with ADHD, while less so for impulsivity. Improvement of one parameter is not necessarily associated with improvement of the other two, and deterioration, especially regarding impulsivity, may occur. If confirmed, these results highlight the need for optimization and individualization of MPH treatment, while monitoring all aspects of the ADHD symptomatology based on the QbTest performance.

- The prevalence of pain in children and adolescents with psychiatric conditions is rarely investigated. The aims of the current study were to (a) describe the prevalence of headaches and abdominal pain in children and adolescents with psychiatric conditions, (b) compare the prevalence of pain in children and adolescents with psychiatric conditions with that in the general population, and (c) investigate the associations between pain experience and different types of psychiatric diagnoses. Families with a child aged 6-15 years who had been referred to a child and adolescent psychiatry (CAP) clinic completed the Chronic Pain in Psychiatric Conditions questionnaire. Information about the child/adolescent's psychiatric diagnosis(es) was extracted from the CAP clinic's medical records. The children and adolescents included in the study were divided into diagnostic groups and compared. Their data were also compared with data of control subjects collected during a previous study of the general population. Abdominal pain was more common among girls with a psychiatric diagnosis (85%) than in the matched control population (62%, p = 0.031). Children and adolescents with neurodevelopmental diagnoses had a higher prevalence of abdominal pain than children and adolescents with other psychiatric diagnoses. Pain conditions in children and adolescents with a psychiatric diagnosis are common and must be addressed.
