- In a large case-control study of Swedish incident type I diabetes patients and controls, 0-34 years of age, we tested the hypothesis that the GIMAP5 gene, a key genetic factor for lymphopenia in spontaneous BioBreeding rat diabetes, is associated with type I diabetes; with islet autoantibodies in incident type I diabetes patients or with age at clinical onset in incident type I diabetes patients. Initial scans of allelic association were followed by more detailed logistic regression modeling that adjusted for known type I diabetes risk factors and potential confounding variables. The single nucleotide polymorphism (SNP) rs6598, located in a polyadenylation signal of GIMAP5, was associated with the presence of significant levels of IA-2 autoantibodies in the type I diabetes patients. Patients with the minor allele A of rs6598 had an increased prevalence of IA-2 autoantibody levels compared to patients without the minor allele (OR=2.2; Bonferroni-corrected P=0.003), after adjusting for age at clinical onset (P=8.0 x 10(-13)) and the numbers of HLA-DQ A1*0501-B1*0201 haplotypes (P=2.4 x 10(-5)) and DQ A1*0301-B1*0302 haplotypes (P=0.002). GIMAP5 polymorphism was not associated with type I diabetes or with GAD65 or insulin autoantibodies, ICA, or age at clinical onset in patients. These data suggest that the GIMAP5 gene is associated with islet autoimmunity in type I diabetes and add to recent findings implicating the same SNP in another autoimmune disease.

- We studied clinical and immunological outcome of Covid-19 in consecutive CLL patients from a well-defined area during month 1–13 of the pandemic. Sixty patients (median age 71 y, range 43–97) were identified. Median CIRS was eight (4–20). Patients had indolent CLL (n = 38), had completed (n = 12) or ongoing therapy (n = 10). Forty-six patients (77%) were hospitalized due to severe Covid-19 and 11 were admitted to ICU. Severe Covid-19 was equally distributed across subgroups irrespective of age, gender, BMI, CLL status except CIRS (p < 0.05). Fourteen patients (23%) died; age ≥75 y was the only significant risk factor (p < 0.05, multivariate analysis with limited power). Comparing month 1–6 vs 7–13 of the pandemic, deaths were numerically reduced from 32% to 18%, ICU admission from 37% to 15% whereas hospitalizations remained frequent (86% vs 71%). Seroconversion occurred in 33/40 patients (82%) and anti-SARS-CoV-2 antibodies were detectable at six and 12 months in 17/22 and 8/11 patients, respectively. Most (13/17) had neutralizing antibodies and 19/28 had antibodies in saliva. SARS-CoV-2-specific T-cells (ELISpot) were detected in 14/17 patients. Covid-19 continued to result in high admission even among consecutive and young early- stage CLL patients. A robust and durable B and/or T cell immunity was observed in most convalescents.

- BackgroundStandardised mortality ratio (SMR) is a common quality indicator in critical care and is the ratio between observed mortality and expected mortality. Typically, in-hospital mortality is used to derive SMR, but the use of a time-fixed, more objective, end-point has been advocated. This study aimed to determine the relationship between in-hospital mortality and 30-day mortality on a comprehensive Swedish intensive care cohort. MethodsA retrospective study on patients >15years old, from the Swedish Intensive Care Register (SIR), where intensive care unit (ICU) admissions in 2009-2010 were matched with the corresponding hospital admissions in the Swedish Hospital Discharge Register. Recalibrated SAPS (Simplified Acute Physiology Score) 3 models were developed to predict and compare in-hospital and 30-day mortality. SMR based on in-hospital mortality and on 30-day mortality were compared between ICUs and between groups with different case-mixes, discharge destinations and length of hospital stays. ResultsSixty-five ICUs with 48861 patients, of which 35610 were SAPS 3 scored, were included. Thirty-day mortality (17%) was higher than in-hospital mortality (14%). The SMR based on 30-day mortality and that based on in-hospital mortality differed significantly in 7/53 ICUs, for patients with sepsis, for elective surgery-admissions and in groups categorised according to discharge destination and hospital length of stay. ConclusionChoice of mortality end-point influences SMR. The extent of the influence depends on hospital-, ICU- and patient cohort characteristics as well as inter-hospital transfer rates, as all these factors influence the difference between SMR based on 30-day mortality and SMR based on in-hospital mortality.

- Background: Several studies describe that patients with heart failure (HF) find it important to discuss prognosis and that they want to be informed about the expectations about the illness progression. However, little is known about their actual preferences for professional communication about prognosis.Purpose: to explore patient’s perspectives regarding communication with health care professionals about the HF prognosis.Methods: 15 patients participated in focus group interviews and a further 9 patients completed individual semi-structured interviews. The patients (75% men, 52-87 years of age) were in NYHA I-III, and were not diagnosed with any other major life threatening disease. Data was analysed using thematic analysis to identify and interpret patterns in the data.Results: One overarching theme was identified: “The tension between hoping for the best and preparing for the worst” with three sub-themes. Ignorance is bliss. Describes how patients preferred to avoid thinking about the HF prognosis because they did not want to lose hope for the future. They lived one day at the time, focusing on here and now, wanting to forget about the illness altogether. Patients also preferred to decide themselves whether they wanted to talk about the prognosis with professionals or not. Nothing but the truth. Describes how patients wanted to know the objective and absolute truth about their illness and its’ prognosis and were afraid to live under false expectations. The truth about their prognosis was that they might die because of their illness. Even though the truth may hurt, they believed that knowing the truth was necessary to live as good as possible. Good news only. Patients described that they knew that HF was a chronic illness but they were ambivalent in their approach towards discussing prognosis. They wanted to know the truth about their prognosis, but at the same time they did not want to know anything since they fear they might hear something they do not want to, as this may hurt. They only wanted to receive “good” and positive information from the professionals, since they perceived such information to be something that they can benefit from.Conclusions: This study shows that patients have different preferences for communication about prognosis and uses different approaches in order to cope living with a serious condition such as heart failure. Professionals need to respect the strategies a patient uses, and be ready to support the patient according to their needs, preferences and life situation.
