Vitamin D is important for bone development with immunomodulatory effects. This study investigated whether feeding CD-1 and interleukin 10 (IL-10) knockout (KO) dams low (25 IU/kg diet) or high (5,000 IU/kg diet) vitamin D affected bone health of dams as well as their offspring. Offspring were weaned to 1 of the 2 diets and followed to young adulthood. Unlike CD-1 dams, IL-10 KO dams experienced greater femur strength with high vitamin D. CD-1 male offspring had reduced femur neck strength and female offspring had smaller, weaker femurs, and weaker lumbar vertebra 2 (LV2) with high maternal vitamin D. IL-10 KO male offspring had larger femurs and female offspring had stronger femurs when weaned to high vitamin D. Low vitamin D did not adversely impact bone health but the optimal level of dietary vitamin D seems to differ between healthy and inflammatory states.

The purpose of this study was to investigate how children with Inflammatory Bowel Disease (IBD) and their families perceived their school experiences in Québec. IBD is one of many “invisible” chronic diseases. It is considered invisible because it occurs internally without significant observable external symptoms. However, children with IBD experience painful and fluctuating physical symptoms caused by intestinal inflammation, as well as the side effects from medications. As a result, they require special accommodations while they attend public or private school. The Québec Education Act (2010) stipulates that adequate services for a diverse student population must be provided. Consequently, the research sought to answer the following questions: What are the experiences of parents and children with IBD enrolled in general education classrooms? And, what are the experiences of their brother or sister? To research these questions, a case study method was used with five families. The two instruments used to collect the data were, (1) individual semi-structured interviews that followed a modified version of Seidman’s (2006) in-depth interviewing approach and (2) drawings of the family by siblings. The data were analyzed inductively. This study was the first to use a qualitative approach with multiple methods that were guided by Bronfenbrenner’s ecological systems theory (1979) and Turnbull and Turnbull’s family systems theory (2001). The findings revealed that, unlike many studies on families of children with special needs, these families with a child with IBD functioned relatively well. At the microsystem level, mothers assumed responsibility as the primary caregiver. Siblings experienced their own challenges, such as feelings of parental neglect. Nonetheless, they also maintained nurturing roles. Within the mesosystem level, the home and school relationship was impacted. Parents and children with IBD experienced school personnel who lacked awareness of IBD and provided insufficient classroom support, especially at public schools. Hence, parents-(predominantly mothers) played an integral role in advocating for necessary accommodations on their child’s behalf. In contrast to many studies on children with disabilities, children with IBD in this research had many friends in and outside of school. In the exosystem, parents struggled with feelings of guilt at having to balance employment and the high financial expense of caring for a child with IBD. They relied on assistance from government services and their IBD association. At the macrosystem level, family members believed that children with IBD were perceived negatively by society because of the lack of public awareness and the stigma that surrounds the topic of incontinence. This study makes contributions to systems theories and provides practical recommendations to school personnel and parents.

Clostridium difficile colitis (CDC) is associated with a higher risk of acute death among hospitalized ulcerative colitis (UC) patients. However, the risk of colectomy with CDC in these patients has varied across studies. No study has assessed the long-term health impact of CDC in UC patients. Therefore, the present study evaluated the impact of CDC on five-year health outcomes of hospitalized UC patients based on Ontario health administrative data. No overall association was observed between CDC and five-year risks of colectomy or death in overall cohort. However, patients who were discharged from hospital without undergoing colectomy demonstrated marginally higher five-year risks of colectomy and hospital re-admission. Mortality risk and length of stay during index hospitalization were also higher in patients with CDC. Analysis of a parallel cohort of UC patients derived using a published case definition corroborated most of these results, but demonstrated a higher five-year mortality risk with CDC.

Bakgrund: Crohns sjukdom och ulcerös kolit är två huvudtyper som utmärker inflammatorisk tarmsjukdom. Inflammatorisk tarmsjukdom påverkar mag- och tarmkanalen och har ett oförutsägbart sjukdomsförlopp. Inflammatorisk tarmsjukdom debuterar vanligtvis i åldern 15-30 och kan ge ogynnsamma konsekvenser i personens dagliga aktiviteter eftersom han eller hon är upptagen med att exempelvis studera, skapa karriär eller bilda familj. Sjukdomarna har flera gemensamma särdrag där de förekommer i så kallade skov med perioder med försämring då tarmslemhinnan blir inflammerad och sårig, vilket leder till symtom som exempelvis blodiga eller slemmiga diarréer, viktnedgång, buksmärtor och trötthet Syfte: Syftet med uppsatsen är att beskriva konsekvenser av att leva med Crohns sjukdom eller Ulcerös kolit hos vuxna personer. Metod: En litteraturöversikt. En litteratursökning gjordes som ledde till sex granskade artiklar. Resultatartiklarna analyserades sedan utifrån det valda syftet. Resultat: I analysen av resultatartiklarna framkom det fem olika återkommande teman. Dessa teman är fysiska konsekvenser av sjukdomen, psykiska konsekvenser av sjukdomen, sociala konsekvenser, förlust av kontroll samt påverkad föräldraroll. Flera teman innehöll subteman. Diskussion: Olika aspekter av patientens liv klarlades i resultatet vilket gör det möjligt för sjuksköterskan att i mötet med patienten kunna ge bra stöd och omsorg. Resultatet uppmärksammar de problem som patienten har i mötet med vårdpersonalen. Genom att upplysa och göra vården uppmärksam kring problemen så kan det underlättas för patienten i hans eller hennes behandling. Genom att lära patienten att hantera sin sjukdom och få behandling vid första tecken på återfall kan hans eller hennes lidande minska. / Background: Two main types that characterize inflammatory bowel disease are Crohn’s disease and ulcerative colitis. Inflammatory bowel disease affecting the digestive tract, and has an unpredictable disease course. Inflammatory bowel disease onset is usually between the ages of 15-30. It can cause adverse effects in a person’s daily activities because he or she is busy studying, building a career, raising a family and so on. Diseases have several common features. They occur in so-called relapses with periods of worsening when the gut lining becomes inflamed and ulcerated. It leads to symptoms such as bloody or slimy diarrhea, weight loss, abdominal pain and fatigue. Aim: The purpose of this paper is to describe the impact of living with Crohn's disease or ulcerative colitis in adults. Methods: A literature review. A literature search was performed which resulted in six peer-reviewed articles. Results Articles were then analyzed based on the selected object. Results: The analysis of the articles revealed five recurring themes. These themes are physical aspects of the disease, mental aspects of the disease, social aspects, and loss of control as well as being a parent whom are living with inflammatory bowel disease. Several themes also hold underlying themes. Discussions: Different aspects of the patients’ life were clarified in the results. It allowed the nurse to be prepared and provide god support and care when meeting with the patient.  The result highlights the problems that the patient has been in meetings with nursing staff. The attention on the problems in the patients’ treatment must be enlightened. By teaching patients to manage their condition and get treatment at the first sign of relapse, his or her suffering will decline.

Risk factors for psychological insult following deployment to Operation Enduring Freedom or Operation Iraqi Freedom among veterans: A systematic review: The systematic review aimed to establish more clearly the risk factors for mental health problems in the veteran population. Five databases were searched. Included studies (n = 10) required that veterans served in Operation Enduring Freedom (OEF) and/or Operation Iraqi Freedom (OIF) and included risk factors of mental health problems among the veteran population. Data from included studies were extracted and critically appraised based on critical appraisal tools following a narrative approach to synthesise data. All of the studies reviewed identified risk factors, although due to their heterogeneous nature key findings varied considerably. However, it was consistently reported that combat exposure and deployment experiences were associated with emergence of post operational mental health problems. The current review provides preliminary evidence that there are a number of specific risk factors that may increase susceptibility to mental health problems subsequent to military deployment. It is suggested that interventions are needed in order to mitigate risk factors and bolster protective factors. A cross-sectional study investigating the impact of disease activity and disease related cognitions on adjustment in Inflammatory Bowel Disease: The research journal aimed to investigate the degree to which psychological illness related cognitions will mediate the effect of disease activity on Quality of Life (QoL). In addition, to assess the impact of disease activity, and several psychological factors, in several adjustments outcomes in IBD to see whether the adjustment variables are significant predictors of multiple outcomes. Mediation was used followed by an exploratory cross-sectional correlational design. Three hundred and thirty eight participants were recruited through an IBD charity and invited to respond to a self-report questionnaire online. Measures targeted different aspects of the IBD profile to give an indication of adjustment associated with IBD diagnosis, psychological factors and Quality of Life (QoL). Mediation analysis found support for significant indirect effects on the relationship between disease activity and QoL through Gastrointestinal (GI) anxiety, perceived disability and illness representations. The subsidiary analysis indicated that pain catastrophising, disease activity, stigma, illness representations and GI anxiety were found to be significant predictors of adjustment in IBD. The results indicate that there is an important relationship with the adjustment factors, QoL, and psychological functioning. In addition, stress, depression, anxiety and QoL were found to be predicted by the adjustment factors. The current study has provided insight into psychological factors and adjustment indicators from a multi-faceted perspective, which will facilitate advancement of managing IBD from a biopsychosocial framework with a view to enable more effective disease management.

Glicocorticoides e outras drogas imunossupressoras são comumente utilizados para o tratamento de condições inflamatórias, como as Doenças Inflamatórias Intestinais (DIIs). Apesar dos avanços na terapia medicamentosa, a remissão da doença ainda é difícil de ser mantida. Devido às suas propriedades imunomodulatórias, as Células-Tronco Mesenquimais (MSCs – Mesenchymal Stem Cells) têm emergido como reguladoras da resposta imune, e sua viabilidade e propriedades migratórias são essenciais para o sucesso da terapia celular. Entretanto, pouco se conhece sobre os efeitos das drogas convencionalmente utilizadas no tratamento das DIIs no comportamento das MSCs. Portanto, o objetivo deste estudo foi avaliar a viabilidade, a morfometria nuclear, a polaridade celular, a distribuição da actina-F e da FAK (Focal Adhesion Kinase), e o comportamento migratório das MSCs na presença das drogas Azatioprina (AZA) e Dexametasona (DEXA). As células foram isoladas de membranas coriônicas humanas e caracterizadas pela diferenciação em adipócitos e osteócitos, bem como pela expressão de um painel de marcadores de superfície. As MSCs foram previamente tratadas com AZA ou DEXA por 24h ou 7d nas concentrações de 1μM ou 10μM, respectivamente. Ambas as drogas não afetaram a viabilidade celular analisada por MTT (3-(4,5-dimethyltiazol-2-yl)-2,5- diphenyltetrazolium bromide) e morfometria nuclear. Entretanto, a análise do índice de polaridade resultou em uma morfologia mais alongada após o tratamento com AZA, enquanto células mais arredondadas foram observadas na presença de DEXA. Os filamentos de actina foram marcados por Rodamina-Faloidina e sua análise mostrou que a AZA preservou parcialmente a formação de lamelipódios e aumentou a presença de fibras de estresse ventrais, enquanto que a DEXA inibiu a formação de lamelipódios, evidenciou uma maior presença de fibras de estresse ventrais e diminuiu a estabilidade das protrusões de membrana, observadas em vídeo. Através da análise de microscopia de série temporal, foi observado que as células sob o efeito da AZA por 7d migraram por maiores distâncias e tiveram um aumento em sua velocidade de migração (24,35%; P < 0,05; n = 4), ao passo que a DEXA diminuiu a velocidade migratória em 24h e 7d (-28,69% e -25,37%, respectivamente; P < 0.05; n = 4) e diminuiu a distância alcançada pelas células. Em conclusão, nossos dados sugerem que as drogas AZA e DEXA podem afetar diferentemente a morfologia e o comportamento migratório das MSCs, possivelmente afetando o resultado da terapia celular. O protocolo de migração celular utilizado neste estudo foi estabelecido por nosso grupo de pesquisa, sendo que um artigo científico contendo todas as etapas do protocolo foi escrito para que outros laboratórios possam utilizá-lo de maneira simples e eficaz. / Glucocorticoids and other immunosuppressive drugs are commonly used to treat inflammatory disorders, such as Inflammatory Bowel Disease (IBD) and, despite few improvements, the remission of IBD is still difficult to maintain. Due to its immunomodulatory properties, Mesenchymal Stem Cells (MSCs) have emerged as regulators of immune response, and its viability and activation of migratory properties are essential for a successful cell therapy. However, little is known about the effects of immunosuppressant drugs used on IBD treatment on MSCs behavior. In this way, the aim of this study was to evaluate MSCs viability, nuclear morphometry, cell polarity, F-actin and FAK (Focal Adhesion Kinase) distribution and cell migration properties in the presence of the immunosuppressive drugs Azathioprine (AZA) or Dexamethasone (DEX). MSCs were isolated from human chorionic membranes and characterized through adipogenic and osteogenic differentiations, as well as a panel of surface markers. Cells were previously treated with AZA or DEX for 24 hrs or 7 days at 1μM and 10μM, respectively. Both drugs had no effects on cell viability analyzed through MTT (3-(4,5- dimethyltiazol-2-yl)-2,5-diphenyltetrazolium bromide) and nuclear morphometry. However, polarity index analysis showed that AZA treatment induced a more elongated cell shape while a greater presence of rounded cells was observed under DEX exposure. F-actin was stained by Rhodamine-Phalloidin and showed that AZA could partially preserve lamellipodia formation and increase the presence of ventral actin stress fibers, while DEX inhibited lamellipodia formation and increased the presence of ventral actin stress fibers while decreasing protrusion stability, observed in video. Through time-lapse microscopy, it was observed that after 7 days of treatment, AZA improved cell the spatial trajectory (ST) and increased migration speed (24.35%, P < 0.05, n = 4) while DEX impaired ST and migration speed after 24 hrs and 7 days treatment (- 28.69% and -25.37%, respectively; P < 0.05, n = 4). In conclusion our data suggests these immunosuppressive drugs can differently affect MSCs morphology and migration capacity, possibly impacting the success of cell therapy. The migration protocol used in this study was successfully established by our group, leading to the writing of a protocol paper to facilitate the usage of this technique by other laboratories in a simple and efficient manner.
