- Triclosan is an antibacterial compound commonly used in cosmetics and personal care products for everyday use. As previously shown, triclosan is found in the plasma, urine and milk from large parts of different human populations. Recent studies have revealed that triclosan is able to activate the human pregnane X receptor in vitro and thus possibly affecting metabolism of drugs in humans via the induction of CYP3A4. Besides, triclosan has been shown to affect thyroid hormonal levels in rats in vivo. In the present study, we investigated if an everyday exposure to triclosan via triclosan-containing toothpaste for 14 days in 12 adult humans caused an increase in plasma 4 beta-hydroxycholesterol, indicative of CYP3A4 induction, and/or alterations in thyroid hormonal status. The plasma triclosan concentrations increased from 0.009-0.81 ng/g to 26-296 ng/g (ranges) upon exposure. Despite this, there were no significant changes in plasma levels of either plasma 4 beta-hydroxycholesterol or thyroid hormones during the exposure. This indicates that the normal use of triclosan-containing toothpaste is not likely to alter metabolism of drugs via CYP3A4 induction or cause adverse events because of thyroid disturbances in humans.

- Objective: To conduct a systematic review of the literature on the longevity of posterior resin composite restorations in adults. Material and methods: A systematic literature search was conducted according to predetermined criteria for inclusion and exclusion. The studies selected were prospective clinical trials with a minimum follow-up time of 4 years, 40 restorations per experimental group and an annual attrition rate of less than 5%. Initially, abstracts and full-text articles were assessed independently and the assessment was subsequently agreed on by five reviewers. The methodological quality of the studies was assessed according to the Swedish Council on Health Technology Assessment (SBU) standard checklist for determining the extent to which studies meet basic quality criteria. Results: In all, the literature search identified 4275 abstracts and 93 articles were read in fulltext. There were eighteen studies which met the criteria for inclusion, eight of which were included in the analysis. There were 80 failures of restorations with a total follow-up time at risk for failure of 62,030 months. The overall incidence rate for all causes of failure was 1.55 lost restorations per 100 restoration years. The most common biological reason for failure (a total of 31 restorations) was secondary caries, with or without fracture of the restoration. The quality of the evidence was low. Conclusions: In an efficacy setting, the overall survival proportion of posterior resin composite restorations is high. The major reasons for failure are secondary caries and restoration fracture which supports the importance of adequate follow-up time. Clinical significance: The overall survival proportion of posterior composite restorations was high, but the results cannot be extrapolated to an effectiveness setting. The importance of adequate follow-up time is supported by the finding that secondary caries often occurred after 3 years or later.

- Objective. To investigate the existence of histamine-excitable nerve fibers in the oral mucosa and to compare the response to histamine provocation in healthy volunteers with that in a small group of patients with chronic oral pain. Material and methods. Thirteen healthy volunteers and six patients suffering from chronic oral pain took part in the study. Blood perfusion was monitored in the hard palate, the tongue, and the skin of the cheek using laser Doppler perfusion imaging (Perimed; Sweden). Baseline scannings were performed, followed by 15 scannings after iontophoresis of histamine (1%). A free description of the sensations was then obtained from the participants after finishing the measurements. Results. Compared to pre-histamine scanning, histamine application resulted in a considerable increase in blood perfusion in all regions (p0.001) that was significantly higher in skin than in oral mucosa (p0.001). There were no significant differences between the healthy volunteers and the patients regarding baseline blood flow, increased blood perfusion, or flare size after histamine provocation. The sensory impression was reported to be more persistent and intense in the skin than in the oral mucosa. No effect on mucosa could be detected by visual inspection. Conclusions. Intra-oral flare could be induced by activating histamine-excitable nerve fibers. Both duration and intensity of the flare were considerably less pronounced than in the control skin site. Histamine application was not clearly associated with itch.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study is to understand how healthy, older adults in Sweden perceive their life situation after retirement. The study is based on a lifeworld approach, and a phenomenographic method was used. Eighteen participants were interviewed, and data were analysed according to the phenomenographic principle of qualitatively different categories. Two categories were developed. The first category, “perceptions that draw attention inward, towards one’s self”, was further described in three subcategories: Sense of decreased status in society, the desire to keep aging at a distance, and contemplation of one’s own existence. The second category, “perceptions that draw attention outward, away from one’s self” was further described in the following four subcategories: caretaking of family members, involvement in social relationships, finding of deep meaning in animals and nature and engagement with society. In the discussion, the findings are further illuminated through comparisons with concepts such as maturity, wisdom and gerotranscendence, and reflections on the findings ‘relevance to a caring context follow. The conclusion suggests this study can provide knowledge that will allow healthcare providers to bridge the gap between generations in order to provide high-quality care. However, for a more profound caring dialogue, for example, about the end of life, a deeper analysis is required.

- Objective: Many physicians find sick-listing tasks problematic. The aim of this study was to identify categories of dilemmas experienced by physicians in their sick-listing practice. Design and subjects: Data was collected at courses that were aimed at improving physicians' sick-listing skills, arranged in different parts of Sweden. Before the course the participants, general practitioners (GP) sent in a written report of a sick-listing case they found problematic. The material consisted of group discussions of some 100 case reports from GPs. The process of categorisation of the dilemmas was a one-step, straightforward qualitative analysis. Results: Eight different categories of sick-listing dilemmas experienced by the physicians were identified. Examples of them are "Not the doctors' pigeon" (when the patients' problem was perceived as not being medical in nature), "Diagnosis as disguise" (when there is a discrepancy between how the patient describes the problems and what the physician apprehends), and "Harmed by sick listing - reversible" (when the physician perceives that the main problem is the iatrogenic adverse effects of sick listing per se). Implications: The contribution of the study is to provide understanding of and labels to the specific difficulties experienced by physicians in their sick-listing practice face to face with patients.

Tidskriftsartikel (refereegranskat)abstract
- Abstract Background. Hodgkin lymphoma (HL) in children constitutes approximately 30% of all pediatric lymphomas in Sweden. The chance of cure is high, but the frequency of late effects has been considerable. Over recent years, efforts have been made to reduce treatment with maintained survival. Material and methods. All patients 0-17 years, identified in the Swedish Childhood Cancer Register as diagnosed between 1985 and 2009, were included. The material was analyzed using descriptive statistics and for survival estimates the Kaplan-Meier method was used. Results. Three hundred and thirty-four patients were identified during this time period. The median age was 14 years. Male sex was over-represented, especially in lower age groups and in nodular lymphocyte predominant Hodgkin lymphoma (NLPHL). In nodular sclerosis and in age group 15-17 years, female sex dominated. Most of the cases presented in stages I or II. B-symptoms were present in 38% of cHL, but only in 7% of NLPHL. The number of patients receiving radiotherapy has been significantly reduced during the period studied. The relapse rate in cHL was 10 ± 2% and in NLPHL 16 ± 7%. The relapse rate was significantly higher in cHL stage IIB compared to other stages in the same therapy group. In cHL 6% died, and in NLPHL 0%. The 5-, 10- and 20-year overall survival estimates in cHL were 96 ± 1%, 95 ± 1% and 90 ± 3%, respectively, with no significant difference when comparing different treatment regimens and time periods. The 5- and 10-year overall survival after relapse in cHL was 81 ± 8% and 75 ± 10%, respectively. Conclusion. During the period studied there is no indication of a decline in survival despite changes in treatment. Survival rates in Sweden are high, and even after relapse chances of cure are high. We were not able to identify any characteristics specific for the group of patients that did not survive.

Hodgkin Lymphoma in children, adolescents and young adults
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Hodgkin lymphoma (HL) is a heterogeneous condition varying from engaging one single lymph node site to a widespread condition. The prognosis with contemporary treatment is excellent for the vast majority. However, the treatment might cause severe late adverse effects in a proportion of the affected individuals.We evaluated all children and adolescents diagnosed in Sweden and registered in the Swedish Childhood Cancer Register over a period of 25 years. The incidence has been stable and the overall survival (OS) is very good, comparable to the best results in the world. Approximately ten percent encountered a relapse, but even after relapse the chances of survival were good. During the study period there were no detectable changes in survival estimates. The use of radiotherapy has decreased.Epstein Barr virus (EBV) and numbers of eosinophils, mast cells and macrophages in the tumors were investigated in 98 cases. Young children were more likely to express EBV. In patients with advanced disease the mast cell and macrophage counts were higher and they also had more affected laboratory parameters. Patients with Nodular Lymphocyte Predominant Hodgkin Lymphoma did not express EBV in the tumor, had significantly lower numbers of eosinophils, mast cells and macrophages and less affected laboratory parameters compared to classical HL.Outcome and clinical presentation were investigated in a cohort of children, adolescents and young adults in Sweden and Denmark and treatment in pediatric and adult departments was compared. OS and event-free survival (EFS) did not differ between the three age groups nor between pediatric and adult treatment. However, the Danish pediatric patients had lower EFS, which corresponded to less use of radiotherapy. Adolescents and young adults shared similar characteristics, while children presented differently with less advanced disease and male preponderance.Hospitalization rates and outpatient visits after end of treatment were evaluated to see whether the excess need of resources described in the literature is evenly distributed among the survivors or whether it is limited to a smaller group. Most of the patients had a low burden of health care use and the relapsing patients were the main drivers of the excess need.

- OBJECTIVES: To study Hodgkin lymphoma (HL) microenvironment in a Swedish paediatric population and its relation to clinical parameters.METHODS: Tumour tissue from classical HL (cHL) (n=87) and nodular lymphocyte predominant HL (NLPHL) (n=11) was investigated for Epstein-Barr Virus (EBV) and analysed for eosinophils, mast cells and macrophages.RESULTS: In cHL, EBV positivity was more common in low age (p<0.001) and in mixed cellularity (MC) (p<0.001). Higher mast cell infiltration was seen in stage III-IV (p<0.001), and with presence of B-symptoms (p=0.01). Cases with high mast cell counts displayed higher erythrocyte sedimentation rate (ESR), lower haemoglobin and albumin levels. Higher macrophage infiltration was seen in stage III-IV (p=0.02) and there was elevated ESR and neutrophil count. All NLPHL cases were EBV negative, had lower rates of inflammatory cells and lower degree of inflammatory reaction in laboratory parameters. There was no difference in survival estimates with regard to infiltration of inflammatory cells.CONCLUSIONS: Higher levels of mast cells and macrophages in cHL tumours reflected the clinical presentation in laboratory parameters, B-symptoms and more advanced stages. NLPHL differs from cHL in numbers of inflammatory cells in the tumour, and in laboratory parameters. This article is protected by copyright. All rights reserved.

Association between the number of coadministered P-glycoprotein inhibitors and serum digoxin levels in patients on therapeutic drug monitoring
- 2004

Tidskriftsartikel (refereegranskat)abstract
- BackgroundThe ABC transporter P-glycoprotein (P-gp) is recognized as a site for drug-drug interactions and provides a mechanistic explanation for clinically relevant pharmacokinetic interactions with digoxin. The question of whether several P-gp inhibitors may have additive effects has not yet been addressed.MethodsWe evaluated the effects on serum concentrations of digoxin (S-digoxin) in 618 patients undergoing therapeutic drug monitoring. P-gp inhibitors were classified as Class I, with a known effect on digoxin kinetics, or Class II, showing inhibition in vitro but no documented effect on digoxin kinetics in humans. Mean S-digoxin values were compared between groups of patients with different numbers of coadministered P-gp inhibitors by a univariate and a multivariate model, including the potential covariates age, sex, digoxin dose and total number of prescribed drugs.ResultsA large proportion (47%) of the digoxin patients undergoing therapeutic drug monitoring had one or more P-gp inhibitor prescribed. In both univariate and multivariate analysis, S-digoxin increased in a stepwise fashion according to the number of coadministered P-gp inhibitors (all P values < 0.01 compared with no P-gp inhibitor). In multivariate analysis, S-digoxin levels were 1.26 ± 0.04, 1.51 ± 0.05, 1.59 ± 0.08 and 2.00 ± 0.25 nmol/L for zero, one, two and three P-gp inhibitors, respectively. The results were even more pronounced when we analyzed only Class I P-gp inhibitors (1.65 ± 0.07 for one and 1.83 ± 0.07 nmol/L for two).ConclusionsPolypharmacy may lead to multiple drug-drug interactions at the same site, in this case P-gp. The S-digoxin levels increased in a stepwise fashion with an increasing number of coadministered P-gp inhibitors in patients taking P-gp inhibitors and digoxin concomitantly. As coadministration of digoxin and P-gp inhibitors is common, it is important to increase awareness about P-gp interactions among prescribing clinicians.

Ingår i: Drug Metabolism And Disposition. - : American Society for Pharmacology & Experimental Therapeutics (ASPET). - 0090-9556 .- 1521-009X. ; 42:3, s. 441-447

Tidskriftsartikel (refereegranskat)abstract
- Drug transporter inhibitors are important tools to elucidate the contribution of transporters to drug disposition both in vitro and in vivo. These inhibitors are often unselective and affect several transporters as well as drug metabolizing enzymes, which can make experimental results difficult to interpret with confidence. We therefore tested 14 commonly used P-glycoprotein (P-gp), breast cancer resistance protein (BCRP), and multidrug-resistance associated protein (MRP) inhibitors as inhibitors of cytochrome P450 (P450) enzyme activities using recombinant enzymes. A subset of P-gp and/or CYP3A inhibitors were selected (cyclosporin A, elacridar, ketoconazole, quinidine, reserpine, and tacrolimus) for a comparison of P450 inhibition in human microsomes and hepatocytes. Most P-gp inhibitors showed CYP3A4 inhibition, with potencies often in a similar range as their P-gp inhibition, as well as less potent CYP2C19 inhibition. Other P450 enzymes were not strongly inhibited except a few cases of CYP2D6 inhibition. MRP and BCRP inhibitors showed limited P450 inhibition. Some inhibitors showed less P450 inhibition in human hepatocytes than human liver microsomes, for example, elacridar, probably due to differences in binding, permeability limitations, or active, P-gp mediated efflux of the inhibitor from the hepatocytes. Quinidine was a potent P450 inhibitor in hepatocytes but only showed weak inhibition in microsomes. Quinidine shows an extensive cellular uptake, which may potentiate intracellular P450 inhibition. Elacridar, described as a potent and selective P-gp inhibitor, displayed modest P450 inhibition in this study and is thus a useful model inhibitor to define the role of P-gp in drug disposition without interference with other processes.

Efflux transporters in ulcerative colitis : decreased expression of BCRP (ABCG2) and Pgp (ABCB1)
- 2007
-
Ingår i: Inflammatory Bowel Diseases. - : Oxford University Press (OUP). - 1078-0998 .- 1536-4844. ; 13:3, s. 291-297

Tidskriftsartikel (refereegranskat)abstract
- Background: Efflux transport proteins are important components of the intestinal barrier against bacterial toxins, carcinogens, and drugs. This investigation was conducted to determine the expression of Breast Cancer Resistance Protein (BCRP/ABCG2), P-glycoprotein (Pgp/MDR1/ABCB1), and Multidrug Resistance Protein 2 (MRP2/ABCC2) in the gut mucosa of patients with ulcerative colitis (UC). Methods: Patients were thoroughly diagnosed according to well-established clinical, endoscopic, and histologic criteria to be included in the group of patients with active UC (n = 16) or UC in remission (n = 17). Colonic and rectal mucosa from patients with UC were compared with tissues from control subjects (n = 15). The mRNA expression (TaqMan) of the efflux transporters and the proinflammatory cytokines interleukin (IL)-1β and IL-6 was determined. Western blot was used in the analysis of protein expression and the tissue localization of BCRP was determined with confocal microscopy. Results: BCRP and Pgp expression was strongly reduced in individuals with active inflammation compared with controls and was negatively correlated with the levels of IL-6 mRNA. The BCRP staining of colonic epithelium seen in healthy mucosa was diminished in inflamed tissues, with concurrent disruption of epithelial F-actin structure. Conclusions: Two of the efflux transporters of importance for the barrier function of the gut mucosa, Pgp and BCRP, are expressed at strongly reduced levels during active inflammation in patients with UC. Investigations are warranted to determine whether the low levels of efflux transporters during active UC contribute to altered transport and tissue exposure of carcinogens, bacterial toxins, and drugs.

Interindividual Variability of Drug Transport Proteins : Focus on Intestinal Pgp (ABCB1) and BCRP (ABCG2)
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The appearance of adverse drug reactions is a common reason for hospitalization in Western countries. Research on underlying biological mechanisms for interindividual variability in drug response aims to better identify patients with exceptional genetic traits, disease conditions or risk of drug-drug interactions and thereby help to prevent adverse drug reactions. Active transport mechanisms are involved in the absorption and disposition of several therapeutic agents. The main objective of this thesis was to investigate factors potentially affecting transport proteins and thus contributing to variability in drug absorption and disposition. Studies of physiological, genetic, environmental, and pathological factors were included. The main focus was the two ATP-binding cassette (ABC) transporters: P-glycoprotein 170 (Pgp) and Breast Cancer Resistance Protein (BCRP). Quantification of transport protein mRNAs along the human intestine indicated that eight of the nine investigated drug transporters were expressed in a region-dependent manner. Effects of drug-drug interactions may therefore vary depending on the site of absorption. The genetic aspect was illustrated by identification of sequence variation in the gene encoding BCRP, the most highly expressed ABC transporter along the human intestine. Drug-drug interactions are important environmental causes of interindividual variability. An evaluation of the effects of Pgp-mediated drug-drug interactions showed that patients receiving Pgp inhibitors had elevated serum concentrations of the Pgp substrate digoxin and that digoxin concentrations were positively correlated with the number of co-administered Pgp inhibitors. The final topic in this thesis was that of drug-disease interactions. BCRP and Pgp were down-regulated during active inflammation in patients with ulcerative colitis. This may contribute to altered concentrations of drug in the intestinal mucosa during periods of inflammation and possibly to changes in drug absorption. To summarize, results of this thesis emphasize the complex background to the interindividual variability of drug transport proteins, where physiological, genetic, environmental and pathological factors all can contribute.

- A vast number of drugs are subjected to active or facilitated transport and multiple transport mechanism may contribute to the net flux during drug absorption. The main objective of this study was to quantify the regional mRNA expression and determine the co-expression of drug transporters from the ABC (Pgp, BCRP, MRP2, MRP3) and SLC (PEPT1, MCT1, OATPB, OCTN2, OCT1) families along the human intestine (duodenum, jejunum, ileum, and colon). A second objective was to compare the transporter expression between the different intestinal regions and Caco-2 cells. Eight out of nine of the investigated transporters exhibited significant regional differences in expression. OATPB was the only transporter that did not show a region-dependency in the expression along the human intestinal canal. The expression of Pgp, BCRP, OCTN2 and MCT1 differed along the small intestine, but the expression differences were greater than five-fold only for Pgp. The rank order of transcript prevalence was identical in the ileum and the jejunum. Between the ileum and colon, seven transcripts were differentially expressed, and MCT1, OCTN2 and MRP3 were expressed at higher levels in the colon than in the small intestine. The expression of transporters in Caco-2 was closest to the expression pattern in the small intestine, although the expression of OATPB, BCRP and MRP2 differed more than five-fold between the Caco-2 cells and ileum. In conclusion, this study provides quantitative data on the expression of transporters from the ABC and SLC families along the human intestine, which can be useful in the interpretation of clinical studies where more than one intestinal transporter contribute to the net transport and in the computer modelling of drug absorption.

- This report summarises our efforts in deriving, characterising and banking of 20 different human embryonic stem cell lines. We have derived a large number of human embryonic stem cell lines between 2001 and 2005. One of these cell lines was established under totally xeno-free culture conditions. In addition, several subclones have been established, including a karyoptypical normal clone from a trisomic mother line. A master cell banking system has been utilised in concert with an extensive characterisation programme, ensuring a supply of high quality pluripotent stem cells for further research and development. In this report we also present the first data on a proprietary novel antibody, hES-Cellect, that exhibits high specificity for undifferentiated hES cells. In addition to the traditional manual dissection approach of propagating hES cells, we here also report on the successful approaches of feeder-free cultures as well as single cell cultures based on enzymatic digestion. All culture systems used as reported here have maintained the hES cells in a karyotypical normal and pluripotent state. These systems also have the advantage of being the principal springboards for further scale up of cultures for industrial or clinical applications that would require vastly more cells that can be produced by mechanical means.

- PURPOSE This study aimed to describe community-dwelling older adults’ perceptions of health and well-being in life after retirement.METHODS This study is part of a larger project using a mixed-methods design to address lifestyles’ influence on community-dwelling older adults’ health. Individual semi-structured interviews were conducted with 18 older adults in age 70 to 95 years. Data were analysed according to a phenomenographic approach.RESULTS The results encompass four categories describing variations in community-dwelling older adults’ perceptions of health and well-being after retirement: feeling well despite illness and disease, interacting with and being useful for oneself and others, independently embracing opportunities and engaging in life, and maintaining a healthy lifestyle.CONCLUSIONS The absence of illness and disease is not a clear prerequisite for a sense of health and well-being. To promote and preserve health and well-being after retirement, older adults strived for—and coached themselves to uphold—a balance in life, focusing on not burdening others. This life orientation after retirement must be acknowledged by society at large, especially from an ageist perspective, and in health and social care to preserve and promote health and well-being.

Tidskriftsartikel (refereegranskat)abstract
- Background: Masticatory parameters, such as reduced number of teeth and posterior contacts, have been shown to be associated with reduced cognitive status. The underlying mechanisms that affect these associations, are however, not well understood. Objectives: The study aims to investigate the association between masticatory dysfunction and cognition and explore the mediating effect of brain structure. Methods: In this cross-sectional study, 45 older adults with subjective masticatory dysfunction (mean age 72.3 +/- 4.0 years) were included. Mini-Mental State Examination score <25, brain trauma, neurological disease, neurodegenerative disorders, depression or poor Swedish language skills were criteria for exclusion. Cognitive functions (executive function and episodic memory) and masticatory dysfunction defined by functional occluding status (FOS; the number of occluding units and number of remaining teeth) were analysed with partial correlation models. Structural magnetic resonance imaging was performed on 28 feasible participants. Multiple regression analyses were performed to evaluate the predictive value of brain structure and white matter hypointensities (WM-hypo) on cognitive functions. A mediation analysis was applied to assess significant predictor/s of the association between FOS and cognition. Results: Both episodic memory and executive functions were positively correlated with FOS. WM-hypo predicted cognitive status (executive function, p = .01). WM-hypo mediated 66.6% (p = 0.06) of the association between FOS and executive functions. Conclusion: Associations between FOS and cognitive functions are reported, where FOS, a potential modifiable risk factor, was related to both episodic memory and executive functions. The mediating effect of WM-hypo on the association between FOS and executive functions highlights the impact of the vascularisation of the brain on the link between mastication and cognition. The present study provides increased knowledge that bridges the gap between masticatory dysfunction and cognition.

- Objective. To evaluate the scientific evidence regarding laser technology for removal of carious tissue. Material and methods. A search for literature on the effect of treatment and on economic aspects of laser technology identified 23 papers. No relevant studies on economic aspects were found. Regarding the effect of treatment, 16 papers were selected for assessment according to established criteria. Results. Cavity preparation and caries excavation by erbium laser were evaluated in three studies of medium quality. The time required to remove carious tissue was evaluated in five studies assessed as being of medium quality for this outcome. In four studies the effect of laser treatment on the dental pulp was included as an outcome but, due to the short follow-up time, the quality was assessed as low. Two studies that included the longevity of the restoration as an outcome were also assessed as being of low quality because the follow-up time was inadequate. Patient response was evaluated in three studies, which were assessed as being of medium quality with respect to this outcome. Conclusions. There is limited scientific evidence that laser treatment is as effective as a rotary bur for removing carious tissue. Treatment time is prolonged. There is limited scientific evidence that adults prefer laser treatment. No conclusions can be drawn regarding biological or technical complications, children's perception of laser treatment or the cost-effectiveness of the method. © 2011 Informa Healthcare.

Forskningsöversikt (refereegranskat)abstract
- The study aimed to evaluate the hypothesis that chewing is a mechanical and physiological contributor to swallowing, physiologic/pathologic processes of the gastrointestinal tract (GIT), and nutrition-related factors. A search strategy was applied to three different databases to investigate if chewing function in adults affects the swallowing, physiologic/pathologic processes of the GIT, and nutrition-related factors compared to controls with no exposure. The included studies were evaluated for methodological quality and risk of bias and certainty of evidence. The results showed 71 eligible studies. Overall, the results showed that 46 studies supported the hypothesis while 25 refuted it. However, the GRADE analysis showed low to very low certainty of the evidence to support the hypothesis that chewing is an important contributor in the swallowing process, and physiologic/pathologic processes in the GIT. The GRADE analysis also showed a moderate to very low certainty of the evidence to suggest that chewing function contributes to nutrition-related parameters. The overall results of the current study showed that a majority (64.7%) of the studies (46 out of 71) supported the hypothesis. However, robust studies with proper design, adequate sample size, and well-defined outcome parameters are needed to establish conclusive evidence.

- Patients with head and neck (H&N) cancer are commonly treated with surgery and/or radiotherapy, which can increase the risk of oral infection, dental caries, and periodontal disease. The present study investigated dental care consumption and costs in patient with H&N cancer before and after the cancer diagnosis. Data from Swedish regional and national registers were used to follow up dental care utilization and dental procedure costs. The analysis included 2,754 patients who had been diagnosed with H&N cancer (exposed cohort) in Stockholm County, Sweden, during 2000–2012 and 13,036 matched persons without cancer (unexposed cohort). The exposed cohort was sub-grouped into irradiated and non-irradiated patients for analysis. The exposed cohort underwent a moderately higher number of dental procedures per year than the unexposed cohort in both the year of the cancer diagnosis and the year after cancer diagnosis; in addition, these numbers were higher in the irradiated than in the non-irradiated subgroup of the exposed cohort. Dental care consumption and costs in the exposed cohort declined over time but remained at a slightly higher level than in the unexposed cohort over the long term (more than two years). Examinations and preventive procedures accounted for most of the higher consumption in the short term (2 years) and at the longer term follow-up. Swedish national insurance subsidized costs for dental treatment, which were highest in the irradiated subgroup and lowest in the unexposed cohort. Direct costs to the patient, however, were similar among the groups. Swedish national health insurance protects patients with H&N cancer from high dental expenditures. Further studies on the cost-effectiveness of preventive dental care for patients are needed.

- Objectives: Medication-induced hyposalivation can increase the risk for oral complications, including dental caries and tooth loss. This problem is particularly important in people with dementia because of their declining ability to maintain oral care. The objective of this study was to describe the association between the number of xerostomic medications used and tooth loss and restorative and dental preventive treatment in a population of persons with dementia. Design: A longitudinal population-based register study with a 3-year follow-up was conducted. Data were extracted from the Swedish Dementia Registry (SveDem), the Swedish Prescribed Drug Register (SPDR), the Swedish National Patient Register (SNPR), and the Dental Health Register (DHR). Setting and participants: Participants were persons with dementia who were registered in the SveDem at the time of their dementia diagnosis. Measures: The exposure was continuous use of xerostomic medications over the 3 years prior to dementia diagnosis (baseline). The outcomes were the incidence of tooth extractions, tooth restorations, and dental preventive procedures. Poisson regression models were used to estimate incidence rate ratios (IRRs) for the association between the exposure and outcomes, adjusting for relevant confounders. Results: A total of 34,037 persons were included in the analysis. A dose-response relationship between the exposure and tooth extractions was observed. Compared with nonusers of xerostomic medication, the rate of tooth extractions increased with increasing number of xerostomic medications used (IRR = 1.03, 1.11, and 1.40 for persons using an average >0-1, >1-3, and >3 xerostomic medications, respectively). However, the risk for having new dental restorations and receiving preventive procedures did not differ between groups. Conclusion: Continuous use of xerostomic medications can increase the risk for tooth extraction in people with dementia. This study highlights the importance of careful consideration when prescribing xerostomic medications to people with dementia, and the need for regular and ongoing dental care.
