Implementing digital sexual and reproductive health care services in youth clinics: a qualitative study on perceived barriers and facilitators among midwives in Stockholm, Sweden.

Background: Digital health care services have the potential to improve access to sexual and reproductive health care for youth but require substantial implementation efforts to translate into individual and public health gains. Health care providers are influential both regarding implementation and utilization of the services, and hence, their perceptions of digital health care services and the implementation process are essential to identify and address. The aim of this study was to explore midwives' perception of digital sexual and reproductive health care services for youth, and to identify perceived barriers and facilitators of the implementation of digital health care provision in youth clinics.

Evaluation of safety and efficacy as an adjuvant for the chitosan-based vaccine delivery vehicle ViscoGel in a single-blind randomised Phase I/IIa clinical trial.

ViscoGel, a chitosan-based hydrogel, has earlier been shown to improve humoral and cell-mediated immune responses in mice. In this study, a Phase I/IIa clinical trial was conducted to primarily evaluate safety and secondarily to study the effects of ViscoGel in combination with a model vaccine, Act-HIB to Haemophilus influenzae type b, administered as a single intramuscular injection. Healthy volunteers of both sexes, ages 22-50 and not previously vaccinated to HIB, were recruited.

Comparative studies of apoptosis in Xenopus laevis and mouse thymoma cell lines.

With the use of in vitro methods and cell lines, functional aspects of apoptosis in the Xenopus laevis B3/B7 and mouse EL4 thymoma cell lines are revealed. Moreover, by using information gleaned from digital imaging and immunocytochemistry, changes in locations of key proteins implicated in apoptotic anti-cancer responses, e.g.

Improved immune responses in mice using the novel chitosan adjuvant ViscoGel, with a Haemophilus influenzae type b glycoconjugate vaccine.

An immune response to an antigen is more efficiently induced in combination with an adjuvant. Chitosan has due to documented immunostimulatory characteristics been proposed as an adjuvant candidate. However, a disadvantage with chitosan is its poor solubility at physiological pH.

Stability of the cathelicidin peptide LL-37 in a non-healing wound environment.

The endogenous cathelicidin peptide LL-37 is strongly expressed at the wound edge early in the process of acute wound healing, but only weakly expressed in chronic wounds. Excessive proteolysis may limit the therapeutic usefulness of exogenous LL-37, especially in ulcers colonized with Pseudomonas aeruginosa that produce elastase, which degrades LL-37. This study investigated the stability of synthetic LL-37 against two types of proteinases in the presence or absence of wound fluid samples (diluted to 10-20%) from nine non-healing venous leg ulcers.
