Annsofie Adolfsson, Emelie Arbhede, Elisabeth Marklund, Per-Göran Larsson, Marie Berg
Advances in Sexual Medicine (ASM) , 2015, DOI: 10.4236/asm.2015.54011
Abstract: Objective: The aim of this paper is to describe the process of developing web information on miscarriage based on scientific evidence, for women and couples in Sweden experiencing miscarriage. Method: A participatory design was used which included researchers, professional experts and users. A participatory design was used involving researchers, professional experts and users. The information was developed in six stages: 1) identifying the needs of information; 2) identifying and constructing the main areas of information and its paths; 3) identifying and inviting experts for revision; 4) developing the text; 5) reviewing the text; 6) design and structuring for adaption to website. Results: The text of information developed gradually based on the seven steps. The final text comprised three parts: 1) what is miscarriage; 2) experiences of miscarriage; 3) processing and planning for new pregnancy. Conclusion: Using participatory design was time and resource consuming, however it was functional for producing appropriate information for the target group. The developed evidence based facts text is assumed to be a complement to the information that is provided by the health care system.
New Putative Chloroplast Vesicle Transport Components and Cargo Proteins Revealed Using a Bioinformatics Approach: An Arabidopsis Model

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0059898
Abstract: Proteins and lipids are known to be transported to targeted cytosolic compartments in vesicles. A similar system in chloroplasts is suggested to transfer lipids from the inner envelope to the thylakoids. However, little is known about both possible cargo proteins and the proteins required to build a functional vesicle transport system in chloroplasts. A few components have been suggested, but only one (CPSAR1) has a verified location in chloroplast vesicles. This protein is localized in the donor membrane (envelope) and vesicles, but not in the target membrane (thylakoids) suggesting it plays a similar role to a cytosolic homologue, Sar1, in the secretory pathway. Thus, we hypothesized that there may be more similarities, in addition to lipid transport, between the vesicle transport systems in the cytosol and chloroplast, i.e. similar vesicle transport components, possible cargo proteins and receptors. Therefore, using a bioinformatics approach we searched for putative chloroplast components in the model plant Arabidopsis thaliana, corresponding mainly to components of the cytosolic vesicle transport system that may act in coordination with previously proposed COPII chloroplast homologues. We found several additional possible components, supporting the notion of a fully functional vesicle transport system in chloroplasts. Moreover, we found motifs in thylakoid-located proteins similar to those of COPII vesicle cargo proteins, supporting the hypothesis that chloroplast vesicles may transport thylakoid proteins from the envelope to the thylakoid membrane. Several putative cargo proteins are involved in photosynthesis, thus we propose the existence of a novel thylakoid protein pathway that is important for construction and maintenance of the photosynthetic machinery.

Sarcoma , 2010, DOI: 10.1155/2010/702573
Abstract: Retroperitoneal sarcomas are rare and treatment should optimally be centralized. Despite successful centralization with 90% of the patients referred prior to surgery, delays occur, which led us to assess lead times in a population-based series. Method. Patients diagnosed with retroperitoneal sarcoma in the southern Sweden health care region 2003–2009 were eligible for the study. Data on referrals and diagnostic investigations were collected from clinical files from primary health care, local hospitals, and from the sarcoma centre. Lead times were divided into patient delays and health care delays caused by primary health care, local hospitals, or procedures at the sarcoma centre. Results. Complete data were available from 33 patients and demonstrated a median patient delay of 23 days (0–17 months) and median health care delay of 94 days (1–40 months) with delays of median 15 days at the general practitioner, 36 days at local hospitals, and 55 days at the sarcoma centre. Conclusion. Centralization per se is not sufficient for optimized and efficient management. Our findings suggest that delays can be minimized by direct referral of patients from primary health care to sarcoma centers and indicate that development of coordinated diagnostic packages could shorten delays at the sarcoma centre.
Functional Analyses of Complement Convertases Using C3 and C5-Depleted Sera
Marcin Okroj, Emelie Holmquist, Ben C. King, Anna M. Blom
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0047245
Abstract: C3 and C5 convertases are central stages of the complement cascade since they converge the different initiation pathways, augment complement activation by an amplification loop and lead to a common terminal pathway resulting in the formation of the membrane attack complex. Several complement inhibitors attenuate convertase formation and/or accelerate dissociation of convertase complexes. Functional assays used to study these processes are often performed using purified complement components, from which enzymatic complexes are reconstituted on the surface of erythrocytes or artificial matrices. This strategy enables identification of individual interactions between convertase components and putative regulators but carries an inherent risk of detecting non-physiological interactions that would not occur in a milieu of whole serum. Here we describe a novel, alternative method based on C3 or C5-depleted sera, which support activation of the complement cascade up to the desired stages of convertases. This approach allows fast and simple assessment of the influence of putative regulators on convertase formation and stability. As an example of practical utility of the assay, we performed studies on thioredoxin-1 in order to clarify the mechanism of its influence on complement convertases.

BMC Pediatrics , 2013, DOI: 10.1186/1471-2431-13-11
Abstract: A population-based, self-reported cross-sectional study conducted in V?stmanland, Sweden with a cohort of 5012 students in the age between 15–18 years old. The participants completed the anonymous questionnaire Survey of Adolescent Life in V?stmanland 2008 during class hour. Psychosomatic symptoms and musculoskeletal pain were measured through index measuring the presence of symptoms and how common they were. DS14 and its two component subscales of negative affectivity (NA) and social inhibition (SI) were measured as well.There was a difference depending on sex, where 10.4% among boys and 14.6% among girls (p?=?< 0.001) were defined as Type D personality. Boys and girls with a Type D personality had an approximately 2-fold increased odds of musculoskeletal pain and a 5-fold increased odds of psychosomatic symptoms. The subscale NA explained most of the relationship between Type D personality and psychosomatic symptoms and musculoskeletal pain. No interaction effect of NA and SI was found.There was a strong association between Type D personality and both psychosomatic symptoms and musculoskeletal pain where adolescent with a type D personality reported more symptoms. The present study contributes to the mapping of the influence of Type D on psychosomatic symptoms and musculoskeletal pain among adolescents.The high prevalence of musculoskeletal and psychosomatic symptoms among adolescents in the western world is a problem involving significant costs for both individuals and societies [1,2]. Musculoskeletal pain and psychosomatic symptoms that appear during adolescence often persist into adulthood and may partly be explained by psychosocial and lifestyle factors [3-5]. Pain among adolescents has been identified as an important public health problem. Roth-Isigkeit found that 83% of children and adolescents had experienced pain during the preceding three months, with headache, abdominal, limb and back pain being the most prevalent types. Pain caused the respondents of th

BMC Medical Informatics and Decision Making , 2009, DOI: 10.1186/1472-6947-9-8
Abstract: A direct observational study was performed at three Swedish mail-order pharmacies which were known to dispense a large proportion of ePrescriptions (38–75%). Data were gathered on all ePrescriptions dispensed at these pharmacies over a three week period in February 2006. All clarification contacts with prescribers were included in the study and were classified and assessed in comparison with all drug prescriptions dispensed at the same pharmacies over the specified period.Of the 31225 prescriptions dispensed during the study period, clarification contacts were made for 2.0% (147/7532) of new ePrescriptions and 1.2% (79/6833) of new non-electronic prescriptions. This represented a relative risk (RR) of 1.7 (95% CI 1.3–2.2) for new ePrescriptions compared to new non-electronic prescriptions. The increased RR was mainly due to 'Dosage and directions for use', which had an RR of 7.6 (95% CI 2.8–20.4) when compared to other clarification contacts. In all, 89.5% of the suggested pharmacist interventions were accepted by the prescriber, 77.7% (192/247) as suggested and an additional 11.7% (29/247) after a modification during contact with the prescriber.The increased proportion of prescriptions necessitating a clarification contact for new ePrescriptions compared to new non-electronic prescriptions indicates the need for an increased focus on quality aspects in ePrescribing deployment. ETP technology should be developed towards a two-way communication between the prescriber and the pharmacist with automated checks of missing, inaccurate, or ambiguous information. This would enhance safety and quality for the patient and also improve efficiency and cost-effectiveness within the health care system.The introduction of electronic transfer of prescriptions (ETP), or ePrescriptions, in ambulatory health care has been suggested to have a positive impact on the prescribing and dispensing processes implying that ePrescribing can improve safety, quality, efficiency and cost-effective

BMC Medical Education , 2011, DOI: 10.1186/1472-6920-11-92
Abstract: A web-based survey was distributed to 500 medical students and 500 business students. We compared levels of study stress (HESI), burnout (OLBI), alcohol habits (AUDIT) and depression (MDI), and analysed their relationship with self-assessed mental health problems by logistic regression, with respect to gender.Medical students' response rate was 81.6% and that of business students 69.4%. Business students scored higher on several study stress factors and on disengagement. Depression (OR 0.61, CI95 0.37;0.98) and harmful alcohol use (OR 0.55, CI95 0.37; 0.75) were both less common among medical students. However, harmful alcohol use was highly prevalent among male students in both groups (medical students 28.0%, business students 35.4%), and among female business students (25.0%). Mental health problems in need of treatment were equally common in both groups; 22.1% and 19.3%, respectively, and was associated with female sex (OR 2.01, CI95 1.32;3.04), exhaustion (OR 2.56, CI95 1.60;4.10), lower commitment to studies (OR 1.95, CI95 1.09;3.51) and financial concerns (OR 1.81 CI95 1.18;2.80)Medical students may not be more stressed than other high achieving student populations. The more cohesive structure of medical school and a higher awareness of a healthy lifestyle may be beneficial factors.Medical students are thoroughly investigated with regard to stress and mental health, and often suggested to be especially subject to stress and also depression [1-3]. Along with these findings, it has been argued that medical education is particularly stressful, but also that medical students carry certain personality traits such as perfectionism or performance-based self-esteem, that make them vulnerable to mental distress [4,5]. We have previously shown that self-rated depression is more common among Swedish medical students than in the general population [3]. Further, some studies report more distress among female medical students than their male peers [3,6], which is in accorda
Protein kinase C inhibition attenuates vascular ETB receptor upregulation and decreases brain damage after cerebral ischemia in rat

BMC Neuroscience , 2007, DOI: 10.1186/1471-2202-8-7
Abstract: At 24 hours after transient middle cerebral artery occlusion (MCAO), the contractile endothelin B receptor mediated response and the endothelin B receptor protein expression were upregulated in the ipsilateral but not the contralateral middle cerebral artery. In Ro-32-0432 treated rats, the upregulated endothelin receptor response was attenuated. Furthermore, Ro-32-0432 treatment decreased the ischemic brain damage significantly and improved neurological scores. Immunohistochemistry showed fainter staining of endothelin B receptor protein in the smooth muscle cells of the ipsilateral middle cerebral artery of Ro-32-0432 treated rats compared to control.The results suggest that treatment with Ro-32-0432 in ischemic stroke decreases the ischemic infarction area, neurological symptoms and associated endothelin B receptor upregulation. This provides a new perspective on possible mechanisms of actions of PKC inhibition in cerebral ischemia.Protein kinase C (PKC) was discovered almost thirty years ago by Takai et al [1]. It has since been shown to include several isoforms, all of which are serine/threonine kinases [2-4]. The PKC isoforms are divided into three subgroups; the conventional, the novel and the atypical PKCs depending on their structure and requirements for activation [3,5,6]. PKC is activated by a range of different stimuli, including growth factors and hormones [5], and it plays a key role in several cardiovascular diseases such as stroke and heart failure [7-9].In previous studies, we have demonstrated that in experimental ischemic stroke and subarachnoid hemorrhage (SAH) there is an upregulation of endothelin type B (ETB) receptors in the cerebral arteries [10,11]. There are two known endothelin receptors in the vasculature of mammals, the endothelin A (ETA) and endothelin B (ETB) receptor [12]. The ETB receptors are normally situated on the endothelial cells, mediating dilatation, but in the case of SAH and experimental ischemic stroke there is an upregul

Abstract: Objective. The aim was to determine efficacy and safety of a surgical method to reduce adult height in extremely tall adolescents. Methods. Data for all girls () and boys () in our center subjected to bilateral percutaneous epiphysiodesis around the knee who had reached final height were included. Final height predictions were based on hand and wrist X-rays before surgery. Results. When compared to prediction, adult height was reduced by cm in treated girls () and cm in treated boys () corresponding to a % and % reduction of remaining growth, respectively. Besides mild to moderate postoperative pain reported in 9 operated individuals, no other side effects were reported. Postoperative X-rays confirmed growth plate closure and absence of leg angulations. Conclusions. Bilateral epiphysiodesis is an effective and safe method to reduce adult height in extremely tall girls and boys.
Inhibition of PKC activity blocks the increase of ETB receptor expression in cerebral arteries
Henriksson Marie,Vikman Petter,Stenman Emelie,Beg Saema
BMC Pharmacology , 2006, DOI: 10.1186/1471-2210-6-13
Abstract: Background Previous studies have shown that there is a time-dependent upregulation of contractile endothelin B (ETB) receptors in middle cerebral arteries (MCA) after organ culture. This upregulation is dependent on mitogen-activated protein kinases and possibly protein kinase C (PKC). The aim of this study was to examine the effect of PKC inhibitors with different profiles on the upregulation of contractile ETB receptors in rat MCA. Artery segments were incubated for 24 hours at 37°C. To investigate involvement of PKC, inhibitors were added to the medium before incubation. The contractile endothelin-mediated responses were measured and real-time PCR was used to detect endothelin receptor mRNA levels. Furthermore, immunohistochemistry was used to demonstrate the ETB receptor protein distribution in the MCA and Western blot to measure which of the PKC subtypes that were affected by the inhibitors. Results The PKC inhibitors bisindolylmaleimide I, Ro-32-0432 and PKC inhibitor 20–28 attenuated the ETB receptor mediated contractions. Furthermore, Ro-32-0432 and bisindolylmaleimide I decreased ETB receptor mRNA levels while PKC inhibitor 20–28 reduced the amount of receptor protein on smooth muscle cells. PKC inhibitor 20–28 also decreased the protein levels of the five PKC subtypes studied (α, βI, γ, δ and ε). Conclusion The results show that PKC inhibitors are able to decrease the ETB receptor contraction and expression in MCA smooth muscle cells following organ culture. The PKC inhibitor 20–28 affects the protein levels, while Ro-32-0432 and bisindolylmaleimide I affect the mRNA levels, suggesting differences in activity profile. Since ETB receptor upregulation is seen in cerebral ischemia, the results of the present study provide a way to interfere with the vascular involvement in cerebral ischemia.
