Religion and the Rwandan genocide

This article discusses the problems concerning the relation of religion and the genocide in Rwanda in 1990. One of the most urgent questions – formulated as an accusation by the present political regime in Rwanda – is whether religion and the influence of the churches and church leaders have, in fact, fuelled the genocide, or even was Christian missionary activity the ultimate cause of the genocide? In the broader circles of the present regime that articulate public opinion, it is argued that the presence of Christianity, more precisely the activities of the Roman Catholic Church, has not only contrib­uted to the possibility of the genocide, but has been at the root of the political constellation that led to the genocide, and that during the genocide, Church leaders were actively involved in it. In many documents, it is argued that the Rwandan genocide would never have taken place, if Christian mis­sions, particularly those of the Roman Catholic Church, had not been estab­lished in Rwanda. Related to this is the question of how the religious change after the genocide is to be interpreted, since in fact, after 1994, many new Christian communities have been founded, and a striking growth of Islam may be noticed.

The impact of biologics on health-related quality of life in patients with inflammatory bowel disease

Lauran Vogelaar1, Adriaan van’t Spijker2, C Janneke van der Woude11Department of Gastroenterology and Hepatology, 2Department of Psychology and Psychotherapy, Erasmus Medical Centre, RotterdamBackground: Inflammatory bowel disease (IBD) is characterized by a chronic relapsing inflammation of the gastrointestinal tract. Adult IBD patients suffer from a disabling disease which greatly affects health-related quality of life (HRQoL). A worse HRQoL in these patients may result in a defensive and ineffective use of medical attention and thus higher medical costs. Because of its chronic nature, IBD may also cause psychological problems in many patients which may also influence HRQoL and care-seeking behavior. An important factor reducing HRQoL is disease activity. Induction of remission and long-term remission are important goals for improving HRQoL. Furthermore, remission is associated with a decreased need for hospitalization and surgery and increased employment, which in turn improve HRQoL. Treatment strategies available for many years are corticosteroids, 5-aminosalicylates and immunnosuppressants, but these treatments did not show significant long-term improvement on HRQoL. The biologics, which induce rapid and sustained remission, may improve HRQoL.Objective: To review and evaluate the current literature on the effect of biologics on HRQoL of IBD patients.Methods: We performed a MEDLINE search and reviewed the effect of different biologics on HRQoL. The following subjects and synonyms of these terms were used: inflammatory bowel disease, Crohn’s disease, ulcerative colitis, quality of life, health-related quality of life, fatigue, different anti-TNF medication, and biologicals/biologics (MESH). Studies included were limited to English-language, adult population, full-text, randomized, double-blind, placebo-controlled in which HRQoL was measured.Results: Out of 202 identified articles, 8 randomized controlled trials (RCT) met the inclusion criteria. Two RCTs on infliximab showed significant improvement of HRQoL compared to placebo which was sustained over the long term. One RCT on adalimumab showed a significant and sustained improvement of HRQoL compared to placebo. This study showed also significant decrease of fatigue in the adalimumabtreated patients. Three RCTs on certolizumab showed a significant improvement of HRQoL in the intervention group compared to placebo. Two RCTs of natalizumab treatment were found. One study showed significant and sustained improvement compared to placebo, and also scores of HRQoL comparable to that in the general population, but in the other no significant results were found.Conclusion: The biologics infliximab, adalimumab, certolizumab, and natalizumab demonstrated significant improvement of HRQoL of IBD patients compared with placebo. However, we found differences in improvement of HRQoL between the different biologics.Keywords: inflammatory bowel disease, health-related quality of life, health care costs, biologic

Focus group interviews reveal reasons for differences in the perception of disease activity in rheumatoid arthritis

Objective: Doctors frequently see patients who have difficulties coping with their disease and rate their disease activity high, despite the fact that according to the doctors, the disease activity is low. This study explored the patients’ perspectives on this discordance that may help to understand why for some patients, usual care seems to be insufficient. Methods: In our qualitative study we conducted focus group interviews where questions were used as a guideline. Transcripts were analyzed using inductive thematic analysis. Findings: Twenty-nine patients participated in four focus groups. Participants could not put their finger exactly on why doctors estimated that their disease activity was low, while they experienced high levels of disease activity. During the in-depth focus interviews, seven themes emerged that appeared related to high experienced disease activity: (1) perceived stress, (2) balancing activities and rest, (3) medication intake, (4) social stress, (5) relationship with professionals, (6) comorbidity, and (7) physical fitness. Conclusion: When patients were asked why their view of their disease activity was different from that of their physician, seven themes emerged. The way participants coped with these themes seemed to be the predominant concept. Specific interventions that focus on one or more of the reported themes and on coping may improve not only the quality of life of these patients but also the satisfaction with the patient–doctor relationship for both parties

Novel Confocal-Laser-Scanning-Microscopy and conventional measures investigating eroded dentine following dentifrice dab-on and brushing abrasion

Objectives To validate novel non-contacting Confocal-Laser-Scanning-Microscopy (CLSM) methodology with conventional Contacting Profilometry (CP) measures investigating brushing or dab-on of stannous-fluoride dentifrice on early aggressive dentine erosion. Methods 75 polished human dentine samples were prepared and eroded in agitated 6% citric acid then randomly allocated into 5 intervention groups; artificial saliva control (1); controlled use of a pressure sensitive counter-rotating oscillatory powered toothbrush with sodium-fluoride NaF (2) or stannous-fluoride SnF2 (3), and dab-on application of NaF (4) or SnF2 (5). Samples underwent three cycles of intervention and 2-min agitated 6 % citric acid challenges. CLSM images were taken and 3D reconstructions produced of step height using a developed software algorithm. In addition, 20 % samples were randomised and profiled using CP to measure step height and surface roughness. Vickers's diamond micro-hardness testing was carried out on all samples. Results Comparing CLSM and CP; Pearson correlation was 0.77 and Intra-class correlation 0.81 (p = 0.01). There were no significant statistical differences in step height between groups using both CLSM and CP. From baseline, SnF2 brushing (3) increased micro-hardness more than control (1) (p = 0.03), NaF (4) and SnF2 dab-on (5) (p ≤ 0.001), and increased surface roughness more than control (p = 0.02), NaF brushing (2) and NaF dab-on (4) (p ≤ 0.017). Dab-on of SnF2 (5) produced rougher surfaces than control (1) (p = 0.014) and reduced hardness compared with NaF brushing (p = 0.04). Conclusions Good agreement and correlation exists between CLSM and CP measures in dentine. There were no significant differences in surface loss after interventions between groups. Compared with control, SnF2 application increased dentine surface roughness and SnF2 controlled powered brushing application increased dentine hardness, likely caused by exposure of uneroded dentine. Clinical significance Isosurfaces produced using CLSM can be used to represent dentine step height loss. They show good correlation and agreement with conventional CP measures, following early aggressive erosion-abrasion cycles of dentine. The CLSM and computer algorithm therefore provides an accurate, standalone and non-contacting three-dimensional measurement of early dentine wear. Stannous-fluoride brushing, and dab-on application offer no benefits following early aggressive erosion in dentine. To reduce dentine wear, limiting erosive challenges and avoiding brushing post-erosion is advised

Associations between tooth wear and dental sleep disorders : A narrative overview

Objectives Tooth wear is a common finding in adult patients with dental sleep disorders. The aim of this paper was to review the literature on the possible associations between tooth wear and the following dental sleep disorders: sleep-related oro-facial pain, oral moistening disorders, gastroesophageal reflux disease (GERD), obstructive sleep apnoea syndrome (OSAS) and sleep bruxism. Methods A PubMed search was performed on 1 June 2018 using MeSH terms in the following query: Tooth Wear AND (Facial Pain OR Temporomandibular Joint Disorders OR Xerostomia OR Sialorrhea OR Gastroesophageal Reflux OR Sleep Apnea Syndrome OR Sleep Bruxism). Results The query yielded 706 reports on tooth wear and the mentioned dental sleep disorders. Several associations between tooth wear and the dental sleep disorders were suggested in the literature. It could be concluded that: (a) tooth wear is associated with dental pain and/or hypersensitivity; (b) oral dryness is associated with tooth wear, oro-facial pain and sleep bruxism; (c) GERD is associated with tooth wear, oro-facial pain, oral dryness, OSAS and sleep bruxism; (d) OSAS is associated with oral dryness, GERD and sleep bruxism; and (e) sleep bruxism is associated with tooth wear. Conclusions Tooth wear is associated with the dental sleep disorders oro-facial pain, oral dryness, GERD and sleep bruxism. The dental sleep disorders are interlinked with each other, which leads to indirect associations as well, and makes the consequences of each single condition difficult to disentangle. Knowledge of these associations is clinically relevant, but more research is needed to confirm their validity.Peer reviewe

Applying Contextual integrity to Open Data Publishing

Open data publishing by both corporate and public bodies has increased significantly in recent years and this type of data could soon be developing into a real commodity. However, not all organisations pay sufficient heed to privacy as part of the decision-making process around open data publication, leaving both the organisation and the users whose data they handle vulnerable to privacy breaches. We present a case study in which we applied contextual integrity in practice, working with a UK local authority using real data. This illustrated how privacy can be incorporated into the decision-making process prior to publication taking place. Our results illustrate the application of Nissenbaum's Contextual Integrity Framework (CI) to the open data domain, and shows that CI is usable in practice
