Background: For the first time the expression of the ion transport protein sodium/potassium-ATPase and its isoforms was analyzed in the human cochlea using light- and confocal microscopy as well as super-resolution structured illumination microscopy. It may increase our understanding of its role in the propagation and processing of action potentials in the human auditory nerve and how electric nerve responses are elicited from auditory prostheses. Material and methods: Archival human cochlear sections were obtained from trans-cochlear surgeries. ⋯ Conclusion: The human auditory nerve displays distinct morphologic features represented in its molecular expression. It was found that electric signals generated via hair cells may not go uninterrupted across the spiral ganglion, but are locally processed. This may be related to particular filtering properties in the human acoustic pathway.

In this paper I describe aspects of work on the human adenoviruses in which my laboratory has participated. It consists of two sections-one historic dealing with work performed in the previous century, and one dealing with the application of 'omics' technologies to understand how adenovirus-infected cells become reprogrammed to benefit virus multiplication.

Background. In cancer, regulatory T-cells (Tregs) were previously believed to inhibit tumor immunity, leading to reduced survival. However, in hematologic malignancies, including T-cell lymphoma (TCL), a correlation between increased numbers of tumor-infiltrating Tregs and a favorable prognosis has been reported. ⋯ Conclusions. Intratumoral Tregs are frequently found in TCL in immunocompetent individuals. In this heterogeneous group of TCL, there was no correlation between the density of intratumoral FoxP3+ cells and overall survival.

Background: Experiences of sexual violence among women can lead to ill health and increase the risk of lifetime co-occurrence of violence. Identifying risk factors and victims facilitates development of effective programmes for treatment and prevention of additional violence. The primary aim of this study was to assess the prevalence and correlates of sexual violence experiences among women seeking care at a family planning unit in Sweden. ⋯ Women with experiences of non-partner sexual violence were more likely to have experiences of intimate partner violence (P < 0.001). Conclusion: Prevalence of sexual violence was high among the respondents. Many women were young when they were exposed to violence, and lifetime co-occurrence of violence was common among women with experiences of non-partner sexual violence.

Heart failure (HF) represents a global pandemic. Although in HF with reduced ejection fraction (HFrEF) randomized controlled trials have provided effective treatments, prognosis still remains poor, with signals of undertreatment. ⋯ Thus, current challenges in the HF field are: 1) optimizing the use of existing treatments in HFrEF; 2) developing and proving efficacy of new treatments, and of new use of existing treatments in HFpEF and HFmrEF. Here we describe how registry-based research can improve knowledge addressing the unmet needs in HF, and in particular we focus on the contribution of the Swedish Heart Failure Registry to this field.
