Introduction: This ex vivo study evaluated the disinfecting and cleaning effects of root canal preparation using sodium hypochlorite irrigation with 3 different needle designs., Methods: Mesial roots from extracted mandibular molars with Vertucci class II configuration were anatomically matched based on micro-computed tomography (micro-CT) analyses and distributed into 3 groups (n = 18/group). The canals were contaminated with a mixed bacterial culture for 30 days and then subjected to preparation using 2.5% sodium hypochlorite irrigation with open-ended flat needle (3 mm short of the working length - WL), closed-ended side-vented irrigation needle (1 mm short of the WL), or a closed-ended plastic needle with 2 lateral outlets (TruNatomy) (1 mm short of the WL). Bacteriological samples were taken from the canals before (S1) and after preparation (S2). After another micro-CT scan, the roots were sectioned and samples were also taken from the apical canal segment (S3). Bacterial reduction was assessed by quantitative real-time polymerase chain reaction. The amount of accumulated hard tissue debris was evaluated by micro-CT., Results: A substantial reduction in bacterial counts was observed in all 3 groups when comparing S1 with S2 (99.95%, 98.93%, and 98.90% in the open-ended, closed-ended, and TruNatomy needle groups, respectively) (P < .01). No significant differences were observed between groups for bacterial reduction in the full and apical canal (P > .05). There were no intergroup differences in the amount of accumulated hard tissue debris either (P > .05). The open-ended needle group showed significantly more specimens with quantitative real-time polymerase chain reaction negative results for bacteria in S3 than TruNatomy (P < .05)., Conclusion: When used up to an appropriate insertion depth, the 3 needle types result in similar antibacterial and cleaning performance, provided variables such as needle size and irrigant type, volume and flow rate are controlled. Exclusive analysis of the apical segment, including the isthmus, revealed that the open-ended needle yielded more cases negative for bacteria., (Copyright © 2024 American Association of Endodontists.

This ex vivo study devised an analytical ex vivo method for infection/disinfection of simulated lateral canals located in the middle and apical segments of the root. The antibacterial effects of supplementary approaches were tested in this model. Extracted mandibular premolars had their main root canals enlarged and then two lateral canals (100 μm in diameter) were created in the root, one in the apical and the other in the middle portion. Micro-computed tomography was used for specimen selection and to confirm the quality of the simulated ramifications. The specimens were contaminated with a mixed bacterial culture from subgingival bacterial biofilm added to pure Enterococcus faecalis strain ATCC 29212 grown overnight, using special strategies to facilitate culture medium penetration within the lateral canals. The following procedures were tested for disinfection: NaOCl/passive ultrasonic irrigation (PUI), NaOCl/XP-endo Finisher, ozonated water/continuous ultrasonic irrigation (CUI), and NaOCl/conventional irrigation with 30-G needles (control). Bacteriological samples were taken from the main canal before (S1) and after (S2) each supplementary protocol, and also from each lateral canal after treatment (S3). DNA extracted from the samples was subjected to quantitative real-time polymerase chain reaction. All S1 main canal samples were positive for bacterial presence. Bacterial counts in the main root canal substantially decreased by 99.2% after PUI, 99.1% after ozone/CUI, 99% after XP-endo Finisher, and 96% in the control group (P < 0.01 for all groups). There were no significant differences between groups (P > 0.05). The same was observed when comparing the effects of the supplementary approaches in the apical and middle lateral canals (P > 0.05). Only a few lateral canals showed no detectable bacteria. The method proposed here proved effective for ex vivo infection/disinfection studies. All supplementary approaches induced a substantial bacterial reduction in the main canal, with no significant differences between them. However, in terms of lateral canal disinfection, none of the tested approaches showed significant effects when compared to the control group., (© 2024. The Author(s).)

Purpose: Glioblastoma (GBM) is an aggressive brain tumor in which primary therapy is standardized and consists of surgery, radiotherapy (RT), and chemotherapy. However, the optimal time from surgery to start of RT is unknown. A high-grade glioma cancer patient pathway (CPP) was implemented in Norway in 2015 to avoid non-medical delays and regional disparity, and to optimize information flow to patients. This study investigated how CPP affected time to RT after surgery and overall survival., Methods: This study included consecutive GBM patients diagnosed in South-Eastern Norway Regional Health Authority from 2006 to 2019 and treated with RT. The pre CPP implementation group constituted patients diagnosed 2006-2014, and the post CPP implementation group constituted patients diagnosed 2016-2019. We evaluated timing of RT and survival in relation to CPP implementation., Results: A total of 1212 patients with GBM were included. CPP implementation was associated with significantly better outcomes (p < 0.001). Median overall survival was 12.9 months. The odds of receiving RT within four weeks after surgery were significantly higher post CPP implementation (p < 0.001). We found no difference in survival dependent on timing of RT below 4, 4-6 or more than 6 weeks (p = 0.349). Prognostic factors for better outcomes in adjusted analyses were female sex (p = 0.005), younger age (p < 0.001), solitary tumors (p = 0.008), gross total resection (p < 0.001), and higher RT dose (p < 0.001)., Conclusion: CPP implementation significantly reduced time to start of postoperative RT. Survival was significantly longer in the period after the CPP implementation, however, timing of postoperative RT relative to time of surgery did not impact survival., (© 2024. The Author(s).)

Objective: To compare the success of establishing spontaneous micturition following immediate trial without catheter (TWOC) to delayed TWOC in males catheterized for acute urinary retention., Materials and Methods: In this systematic review, we included studies reporting success rates of immediate TWOC or delayed TWOC (≤30 days) among males ≥18 years of age catheterized for acute urinary retention. We excluded studies on suprapubic catheterization, postoperative/perioperative catheterization and urinary retention related to trauma. We searched the following databases: MEDLINE, Embase, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Open Grey and Clinicaltrials.gov. The search was concluded on 30 November 2022. There were no restrictions on language or publication date. Risk of bias was assessed using the ROB 2.0 and ROBINS-I tools. We did random-effects restricted maximum likelihood model meta-analyses. Certainty of evidence was assessed using GRADE., Results: We included 61 studies. In two randomized controlled trials (RCTs), both with some concerns for risk of bias, including in total 174 participants, the relative success rate was 1.22 (95% CI 0.84-1.76) favouring delayed TWOC. In two comparative cohort studies, both with serious risk of bias, including 642 participants, the relative success rate was 1.18 (0.94-1.47) favouring delayed TWOC. One study was excluded from this meta-analysis because of critically low quality. Four studies reporting success rates for cohorts with immediate TWOC, all with serious risk of bias, including 409 participants, had an overall success rate of 47% (29-66). Fifty-two studies reporting success rates for cohorts with delayed TWOC, all with serious risk of bias, including 12 489 participants, had an overall success rate of 53% (49-56). The certainty of the evidence was considered low for the RCTs and very low for the rest., Conclusion: There was a limited number of appropriately designed studies addressing the research question directly. The evidence favours neither approach., Competing Interests: The authors report no conflict of interests., (© 2024 The Authors.

Objective: We studied the nutritional status of older adult adults receiving home nursing care using demographic data, household category, polypharmacy, and potentially inappropriate medications (PIMs)., Design: Cross-sectional study., Setting and Participants: Two Norwegian municipalities during 2017-2019; home nursing service clients aged ≥70 years., Methods: Inclusion of patients and data collection were done by nurses working in the home services. Recorded data were participants' age, sex, living alone or with others, nutritional status (Mini Nutritional Assessment-Short Form and body mass index), regular prescription drugs, and potentially inappropriate medications (PIMs) according to the Norwegian General Practice Nursing home (NORGEP-NH) criteria. Descriptive statistics and logistic regression were used., Results: Of the 270 patients (mean age 84.2 years; 64.8% females; 188 living alone), 25 (9.3%) were malnourished and 154 (57%) at risk of malnutrition; in addition, 14.8% had a BMI <21 and 27.8% had lost weight in the previous 3 months. The odds for being at malnutrition risk was higher if living with others vs living alone: adjusted odds ratio (OR) 2.23 (1.20-4.13). Female sex, older age, and better mobility was associated with living alone. The mean number of regular drugs was 7.3. Overall, 43.3% of the participants used at least 1 PIM. Using 0 to 5 drugs vs ≥6 drugs (polypharmacy) was associated with higher odds for malnutrition risk: adjusted OR 1.97 (1.04-3.75). Compared with well-nourished patients, those at risk for or who were malnourished used fewer cardiovascular and musculoskeletal drugs. Exposure to PIMs was not associated with nutritional status., Conclusions and Implications: Two-thirds of home nurse clients were either malnourished or at risk for malnutrition. Living with others or using fewer daily drugs implied increased risk for malnourishment, probably reflecting differences in morbidity and possible inappropriateness of medication use. Future research on nutritional status and medication use should aim for including more clinical data than simple drug counts., Competing Interests: Disclosure The authors declare no conflicts of interest., (Copyright © 2023 The Authors.

Objective : We opted to study how support staff operational capacity and diabetes competences may impact the timeliness of basal insulin-initiation in general practice patients with type 2 diabetes (T2D). Design/Setting/Outcomes: This was an observational and retrospective study on Norwegian primary care patients with T2D included from the ROSA4-dataset. Exposures were (1) support staff size, (2) staff size relative to number of GPs, (3) clinic access to a diabetes nurse and (4) share of staff with diabetes course (1 and 2 both relate to staff operational capacity, whereas 3 and 4 are both indicatory of staff diabetes competences). Outcomes were 'timely basal insulin-initiation' (primary) and 'attainment of HbA 1c <7%' after insulin start-up (secondary). Associations were analyzed using multiple linear regression, and directed acyclic graphs guided statistical adjustments. Subjects: Insulin naïve patients with 'timely' ( N  = 294), 'postponed' ( N  = 219) or 'no need of' ( N  = 3,781) basal insulin-initiation, respectively. Results: HbA 1c [median (IQR)] increased to 8.8% (IQR, 8.0, 10.2) prior to basal insulin-initiation, which reduced HbA 1c to 7.3 (6.8-8.1) % by which only 35% of the subjects reached HbA 1c <7%. Adjusted risk of 'timely basal insulin-initiation' was more than twofold higher if access to a diabetes nurse (OR = 2.40, [95%CI, 1.68, 3.43]), but related only vaguely to staff size (OR = 1.01, [95%CI, 1.00, 1.03]). No other staff factors related significantly to neither the primary nor the secondary outcome. Conclusion: In Norwegian general practice, insulin initiation in people with T2D may be affected by therapeutic inertia but access to a diabetes nurse may help facilitating more timely insulin start-up.

Background: Parental behavior and infant sleep patterns can vary widely both within and between cultures and settings. Breastfeeding during the second half-year of infancy has been associated with frequent night waking, which is perceived as sleep problem among the Western societies. An understanding of sleeping patterns among breastfed infants during the second half-year of infancy is important in supporting continued breastfeeding., Objectives: The study aimed to investigate the sleeping patterns among breastfed infants during second half-year of infancy., Methods: This is a cross-sectional study. Three hundred and forty-two mothers of 6-12 months old breastfed infants completed the questionnaires on socio-demographic factors, breastfeeding practices, and infant sleeping patterns, which were assessed by using the Brief Infant Sleep Questionnaire (BISQ). The Cox regression model was used to assess the factors that were associated with night sleep duration whereas demographic factors and breastfeeding practices that were associated with night waking frequency were investigated using the Poisson regression model., Results: On average, the breastfed infants slept for 11 h during the night and most infants were reported to have night waking (96.8%) and were breastfed at least once at night (93.5%). In the adjusted analyses, infants in the age group 9-12 months were less likely to sleep longer compared to infants in the 6-8 months age group [HR 1.52 95% CI (1.17, 1.98)]. A one-hour increase in daytime sleep and in night wakefulness increased the likelihood of waking up at night by 19% and 24%, respectively. Infants who had been vaccinated within the last 7 days and infants who were breastfed to sleep were more likely to have a shorter nighttime sleep duration. Nighttime breastfeeding frequency was significantly associated with a 17% increase in the likelihood of night waking [IRR 1.17 95% CI (1.13, 1.22)]. Infants who slept on their parents' bed were 1.28 times more likely to wake up at night compared to infants who slept in a separate room [IRR 1.28 95% CI (1.05, 1.59)]. Infants of parents who reported that their infants' sleep was not a problem were 34% less likely to wake up compared to infants of parents who reported that their infants' sleep was a problem [IRR 0.66 95% CI (0.49, 0.87)]. CONCLUSIONS FOR PRACTICE: Frequent night waking, bed sharing and night breastfeeding were common among 6-12 months old breastfed infants. Frequent night breastfeeding may lengthen an infant's nighttime sleep duration. The study findings indicate that adequate information and support should be given to breastfeeding mothers in relation to the sleeping pattern of breastfed infants in order to promote continued breastfeeding practices., (© 2023.

Introduction: This study used a correlative multianalytical approach to investigate the bacteriologic conditions in the apical root canal system of treated teeth with or without apical periodontitis and their correlation with the technical quality of the previous root canal obturation and the presence and volume of apical periodontitis lesions., Methods: Root apexes were obtained from recently extracted root canal-treated teeth with (n = 23) and without (n = 22) apical periodontitis lesions as demonstrated by cone-beam computed tomographic examination. The root apexes were sectioned and subjected to micro-computed tomographic (micro-CT) scanning. The specimens were cryopulverized, and DNA extracted from the powder was used as a template in real-time polymerase chain reaction assays to quantify total bacteria and members of the Streptococcus genus and Actinobacteria phylum. The bacteriologic findings were compared between the 2 groups and also evaluated for associations with cone-beam computed tomographic and micro-computed tomographic data., Results: Bacteria were detected in all apical canal samples except 1. The mean counts of total bacteria, streptococci, and actinobacteria did not differ significantly between teeth with or without apical periodontitis (P > .05). Streptococcus levels were significantly lower by 80% in the apical canals of teeth with small lesions compared with those without lesions (P < .05). The limit of filling >2 mm short was significantly associated with more total bacterial counts compared with canals filled 0-2 mm short (P < .05). An adequate coronal restoration was significantly associated with lesser counts of Streptococcus (P < .05)., Conclusions: Comparable bacterial loads were observed in the apical canal system of treated teeth with and without apical periodontitis, suggesting that factors other than only the total bacterial levels may also influence the development and progression of apical periodontitis. Bacteria were found in the apical canal in virtually all cases with a high prevalence of streptococci and actinobacteria. Streptococci counts were significantly higher in the apical canal of teeth with inadequate restorations and teeth with no lesions. Underfilled canals showed higher bacterial counts., (Copyright © 2023 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.)

The main objective of this systematic review was to assess cancer risk, and mortality after cancer diagnosis, for exclusive users of Swedish snus, compared with non-users of tobacco. We followed international standards for systematic reviews and graded our confidence in the risk estimates using the GRADE approach. Our search gave 2450 articles, of which 67 were assessed in full text against our inclusion criteria. Of these, 14 cohort-studies and one case-control study were included in the review. The studies investigated risk of cancer in the oral cavity or oropharynx (3 studies), esophagus (1 study), stomach (1 study), pancreas (2 studies), colorectum (2 studies), anus (1 study) and lung (1 study), as well as malignant lymphoma (1 study), leukemia and multiple myeloma (1 study), melanoma (1 study), any cancer (1 study) and mortality after cancer diagnosis (4 studies). Cancer risk could only be evaluated in men as there was a general lack of data for women. All included studies were evaluated to have a moderate risk of bias, mostly related to validity of exposure information. An increased risk of cancer of the esophagus, pancreas, stomach and rectum as well as an association between use of snus and increased mortality after a cancer diagnosis was reported. Our confidence in the various risk estimates varied from moderate through low to very low., (© 2023 The Authors.

Overweight and obesity are among the most serious health problems of our time. A majority of patients with overweight and obesity will first get in touch with health services through primary care. This makes it crucial to develop strategies to enable physicians in primary care to help and treat patients with overweight and obesity. The physicians tend to avoid this subject. The main reason is reported to be lack of knowledge and education, and that they have nothing concrete to offer their patients. We wanted to examine if a simple method with specific measures could be used in Norwegian general practice and achieve meaningful weight loss. 23 physicians and 210 patients participated in the study. The physicians who participated were cluster randomised into either control group or intervention group. The physicians in the control group were told to follow their usual approach, while the physicians in the intervention group followed a fixed plan with specific diets given orally and in writing to the patients. The inclusion criteria for both groups were: body mass index (BMI)>30 kg/m 2 , or BMI>25 kg/m 2 with at least one weight-related condition. Weight was measured at the start, then after 1 year and finally after 2 years in both groups. We found no significant weight loss in the control group. In the intervention group, there was a weight loss of at least 10% by 25.5% after the first year and 24.2% after the entire observation period. 53.5% of the patients lost at least 5% of their weight in the first year and nearly 45% after the entire observation period. We conclude that a simple tool with a specific diet and activity plan is feasible in general practice and may produce significant weight loss.

Objective: To investigate changes in FPs' self-reported clinical practices after participation in a comprehensive 1-year cognitive behavioural therapy (CBT) training course., Design: Cross-sectional study., Setting: Norway., Participants: Family physicians., Main Outcome Measures: Impact of the CBT training course on FPs' delivery of CBT to patients and their use of referral to specialized mental health care providers., Results: Of the 217 FPs who had participated in the training course between 2009 and 2016, 124 completed the survey (response rate=57.1%); 99.2% of participating FPs reported using CBT tools daily in patient consultations, more than three-quarters reported changing the way they organized their workdays to accommodate CBT, and 75.0% reported using structured CBT consultations at least monthly after completing the course. The most common patient groups receiving structured CBT were those experiencing mild or moderate depression (22.8%), anxiety disorders (30.4%), or a combination of an anxiety disorder and depression (43.5%). The odds of making fewer referrals to specialized mental health care providers were 5.4 times higher among FPs who used Socratic questioning ( P =.02), 4.7 times higher among those who provided consultation summaries ( P =.01), and 3.3 times higher among those who had participated in a refresher course ( P =.05)., Conclusion: Comprehensive training in CBT promotes the use of CBT tools and strategies in family practice. Further longitudinal research (ideally randomized controlled studies) on patient outcomes related to CBT provided in family practices is required., (Copyright © 2023 the College of Family Physicians of Canada.)

Objective: Use of snus, a moist, smokeless tobacco product, may lead to local changes in the oral mucous membrane in the area where the snus is placed. It can also cause irreversible gingival retraction. This cross-sectional study aimed to investigate the relationship between use of snus, oral mucosal lesions (snus induced lesions) and gingival retractions among adolescents in Norway., Material and Methods: All 18-20 years olds visiting public dental health clinics in the south-eastern region of Norway between October 2015 and December 2016 were invited to participate. All participants ( n  = 1363) filled in an electronic questionnaire before a clinical examination. Of these, 216 used snus daily., Results: Snus induced lesions were observed in 79.2% of daily snus using participants. In adjusted regression analyses, the odds of having a more severe lesion as opposed to a less severe lesion were 1.12 times greater for each additional box of snus used in a month ( p  < .01). Women were 46% less likely to have a severe lesion than men ( p  = .03). Gingival retractions were observed in 18.4% of the participants. The odds for dental retraction were significantly higher by 34% for each year of snus use., Conclusions: Most of the adolescents using snus had snus induced lesions, whereas approximately one-fifth had gingival retractions. The severity of the lesion and gingival retraction increased with the amount of snus boxes used and the duration of the snus use, respectively.

Objectives: To study clinical and radiographic outcomes after non-surgical treatment of peri-implantitis using either an oscillating chitosan brush (OCB) or titanium curette (TC) and to observe changes in clinical signs of inflammation after repeated treatment., Methods: Thirty-nine patients with dental implants (n = 39) presented with radiographic bone level (RBL) of 2-4 mm, bleeding index (BI) ≥ 2, and probing pocket depth (PPD) ≥ 4 mm were randomly assigned to mechanical debridement with OCB (test) or TC (control). Treatment was performed at baseline and repeated at 3, 6, and 9 months in cases with > 1 implant site with BI ≥ 1 and PPD≥4 mm. Blinded examiners recorded PPD, BI, pus, and plaque. The radiographic bone level change between baseline and 12 months was calculated. A multistate model was used to calculate transitions of BI., Results: Thirty-one patients completed the study. Both groups exhibited a significant reduction in PPD, BI, and pus at 12 months compared to baseline. Radiographic analysis showed stable mean RBL in both groups at 12 months. There was no statistically significant difference in any of the parameters between the groups., Conclusions: Within the limitations of this 12-month multicenter randomized clinical trial, non-surgical treatment of peri-implantitis with OCB or TC showed no statistically significant differences between the groups. Clinical improvements and, in some cases, disease resolution, was observed in both groups. However, persistent inflammation was a common finding which further puts emphasis on the need for further treatment., (© 2023 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: Providing dental services to dependent older adults might be challenging because of physical and cognitive decline. The present study aimed to explore current practices, knowledge, and experienced challenges related to the treatment of older adults in home health care services (HHCS) among dentists and dental hygienists in Norway., Methods: An electronic questionnaire survey was distributed to Norwegian dentists and dental hygienists, inquiring about background characteristics, current practices, self-perceived knowledge, and challenges when providing oral health care for older HHCS patients., Results: Four hundred and sixty-six dentists and 244 dental hygienists treating older HHCS patients responded to the survey. The majority were female (n=620; 87.3%) and worked in the public dental service (PDS) (n=639; 90%). When older HHCS adults attended the dental practice, the treatments provided were most frequently aimed at relieving acute oral problems, although dental hygienists reported to focus on improving oral health more often than dentists. Dentists reported to have more self-perceived knowledge than dental hygienists regarding patients with complex treatment needs, cognitive or physical impairment. Exploratory Factor Analysis (EFA) was carried out on the 16 items related to challenges, three factors were extracted and Structural Equation Models (SEMs) were performed. Challenges related to dental care for older HHCS adults were related to time, practical organization and communication. Variation within these categories was associated with sex, graduation year and country, as well as time used per patient and work sector, but not with professional status., Conclusions: The results indicate that dental care for older HHCS patients is time-demanding and more often aimed at relieving symptoms than improving oral health. A substantial proportion of dentists and dental hygienists in Norway lack confidence when providing dental care for frail elderly., (© 2023. The Author(s).)

Background: Social support is associated with higher self-reported physical activity (PA) in postpartum women, but it is unknown if similar association occur when using objective PA data. The aim was to explore the associations between social support and objectively recorded moderate-to-vigorous physical activity (MVPA) postpartum, and if associations differed across ethnic groups., Methods: We used data from 636 women who participated in the STORK Groruddalen cohort study (2008-2010). MVPA minutes/day in bouts of ≥ 10 minutes was recorded by SenseWear Armband™ Pro 3 (SWA) over 7 days, 14 weeks postpartum. Social support for PA from family or friends was measured by a modified 12-item version of the Social Support for Exercise Scale. We used single items, family support mean score (6 items) and friends' support mean score (6-items) in four separate count models, and adjusted for SWA week, age, ethnicity, education, parity, body mass index and time since birth. We tested interactions between social support and ethnicity. Analyses were performed on complete cases and imputed data., Results: Based on imputed data, we observed that women who reported low and high support from family accumulated 16.2 (IQR: 6.1-39.1) and 18.6 (IQR: 5.0-46.5) MVPA minutes/day, respectively. Women who reported low and high support from friends accumulated 18.7 (IQR: 5.9-43.6) and 16.8 (IQR: 5.0-45.8) MVPA minutes/day. We observed a 12% increase in MVPA minutes/day for each additional increase in mean family support score (IRR = 1.12, 95% CI: 1.02 to 1.25). Women reporting high level of support from family on 'discuss PA', 'co-participation' and 'take over chores' accumulated 33%, 37% and 25% more MVPA minutes/day than women reporting low level of support respectively ('discuss PA': IRR = 1.33, 95% CI: 1.03 to 1.72, 'co-participation': IRR = 1.37, 95% CI: 1.13 to 1.66 and 'take over chores': IRR = 1.25, 95% CI: 1.02 to 1.54). Associations were not modified by ethnicity. No statistically significant association between support from friends and MVPA was observed. Similar results were found in complete case analyses, with a few exceptions., Conclusion: Overall family support and specific forms of support from family were associated with MVPA across ethnic groups, while support from friends was not associated with MVPA postpartum., (© 2023.

Aim: We investigated factors associated with the initiation and continuation of snus use in adolescents in Norway. The associations with adolescents' own educational plans, the parents' educational level(s) and tobacco habits were estimated., Methods: In this cross-sectional questionnaire-based study, 1465 patients aged 18-20 years participated. The questionnaire was administered at regular dental examinations in the public dental health service. To assess the association between individual factors and the initiation of tobacco habits, a generalised structural equation model with random effects at the clinic level was used. Binary responses were modelled using multilevel binary logistic regression, while the number of snus boxes used per month was modelled using a multilevel Poisson regression model., Results: Of current (daily and occasional) tobacco users, 85% were snus users, including dual users of both snus and cigarettes. The median age of snus initiation was 16 years. Both parental snus use and smoking were associated with an increased risk of snus initiation, snus use and a higher amount of use. An increased risk of using snus was associated with male gender and with no educational plans or planning for further vocational education. The amount of snus used was higher among current snus users with a prior smoking history and among those planning for further vocational education., Conclusions: These findings may aid in developing and targeting tobacco prevention strategies aimed at young people. Tobacco prevention measures should start at the elementary school level. The strong association with parental tobacco habits underlines the importance of parents' influence on their children's tobacco use.

In pursuit of universal health coverage, many low- and middle-income countries are reforming their health financing systems and introducing health insurance schemes. As part of these reforms, lawmakers in The Gambia enacted 'The National Health Insurance Bill, 2021'. The Act will establish a National Health Insurance Scheme (NHIS) that pays for the cost of healthcare services for its members. This study assessed Gambians' willingness to pay (WTP) for a NHIS. Using multistage sampling design with no replacement, head/co-head of households were presented with a hypothetical health insurance scheme from July to August 2020. Their WTP and factors influencing WTP were elicited using a contingent valuation method. Descriptive statistics were used to describe sample characteristics. Lopez-Feldman's modified ordered probit model and linear regression were applied to estimate respondents' WTP as well as identify factors that influence their WTP. More than 90% of the respondents-677 (94.4%) were willing to join and pay for the scheme. Half of these respondents-398 (58.8%) agreed to pay the first bid of US dollars (US$) 20.78 or Gambian dalasi (GMD) 1000. The average WTP was estimated at US$23.27 (GMD1119.82), whereas average maximum amount to pay was US$26.01 (GMD1251.16). Results of the two models together showed that gender, level of education and household income were statistically significant, with the latter showing negative influence on WTP. The study found that Gambians were largely receptive to the scheme and have stated their willingness to contribute. Our findings can inform policymakers in The Gambia and other sub-Saharan countries when establishing contribution rates and exemption criteria during social health insurance scheme implementation., (© The Author(s) 2022.

Aim: The aim of the study was to examine the 20-year trend in dental caries and associated determinants among adults in Lithuania after the country restored its independence., Material and Methods: Data from two cross-sectional national surveys included samples of 35-44-year-olds (adults) and 65-74-year-olds (early elderly). The 1997/1998 survey (first survey) recruited a stratified random sample of 569 individuals from 10 selected areas in Lithuania (response rate 52%), and the 2017/2019 survey (second survey) recruited a stratified random sample of 723 individuals from 5 biggest Lithuanian cities and one randomly selected peri-urban/rural area from each of 10 Lithuanian counties (response rate 53%). The information about the social (sex, residence, education) and behavioral (toothbrushing frequency, use of fluoridated toothpaste, and last dental visit) determinants was collected via self-reports using the World Health Organization (WHO) Oral Health Questionnaire for Adults questions. Information about the fluoride level in the drinking water was retrieved from the water suppliers. Dental caries was recorded at the surface level following the WHO criteria by two calibrated examiners, one at each of the national surveys. Bivariate and multivariate analyses were used., Results: According to multivariable negative binomial regression analysis, in adults, 67% lower DS scores (IRR 0.33, 95% CI 0.26-0.42) and in early elderly 47% lower DS scores (IRR 0.53, 95% CI 0.38-0.74) were observed in the second survey. Adults in the second survey (vs. first survey) had 62% lower MT scores (IRR 0.38, 95% CI 0.32-0.46), and the early elderly had 19% lower MT scores (IRR 0.81, 95% CI 0.72-0.92). Adults in the second survey had 21% lower DMFT scores (IRR 0.79, 95% CI 0.73-0.85). The changes in behavioral determinants were observed over the 20-year period., Conclusion: An improvement in dental health during the 20-year period, mainly related to reduction in untreated caries and missing teeth, was observed in adults and early elderly. However, early elderly still had high numbers of missing teeth. The decrease in total caries experience during the 20 years was significant only in adults. Our findings support an urgent need to design and implement national oral health promotion and prevention programs with increased focus on oral self-care and fluoridated toothpaste use., (© 2023 S.

Objectives: We estimate the prevalence of sexually transmitted infection (STI) among patients after sexual assault, assess the possible value of azithromycin prophylaxis, and identify risk factors for assault-related STI and for not presenting at follow-up., Design: Prospective observational cohort study., Setting: Sexual assault centre in Oslo, Norway., Participants: 645 patients, 602 (93.3%) women and 43 (6.7%) men, attending the centre from May 2017 to July 2019., Outcome Measures: Microbiological testing at the primary examination and at follow-up consultations after 2, 5 and 12 weeks. Estimated relative risk for assault-related STI and for not presenting at follow-up., Results: At primary examination, the prevalence of genital chlamydia was 8.4%, Mycoplasma genitalium 6.4% and gonorrhoea 0.6%. In addition, the prevalence of bacterial STI diagnosed at follow-up and possibly from the assault was 3.0% in total: 2.5% for M. genitalium, 1.4% for genital chlamydia and 0.2% for gonorrhoea. This prevalence did not change when azithromycin was no longer recommended from January 2018. There were no new cases of hepatitis B, hepatitis C, HIV or syphilis. We found no specific risk factors for assault-related STI. Patients with previous contact with child welfare service less often presented to follow-up (relative risk (RR) 2.0 (95% CI 1.1 to 3.5)), as did patients with a history of sex work (RR 3.6 (1.2 to 11.0)) or substance abuse (RR 1.7 (1.1 to 2.7))., Conclusions: Most bacterial STIs were diagnosed at the primary examination, hence not influenced by prophylaxis. There was no increase in bacterial STI diagnosed at follow-up when azithromycin prophylaxis was not routinely recommended, supporting a strategy of starting treatment only when infection is diagnosed or when the patient is considered at high risk. Sex work, substance abuse and previous contact with child welfare services were associated with not presenting to follow-up., Trial Registration Number: ClinicalTrials.gov Registry (NCT03132389)., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objectives: This prospective, parallel-group, examiner-blinded, multicentre, randomized, controlled clinical trial aimed to assess the efficacy of an oscillating chitosan brush (OCB) versus titanium curettes (TC) on clinical parameters in the non-surgical treatment of peri-implantitis., Material and Methods: In five dental specialist clinics, 39 patients with one implant with mild to moderate peri-implantitis, defined as 2-4 mm radiographic reduced bone level, bleeding index (BI) ≥ 2, and probing pocket depth (PPD) ≥ 4 mm were randomly allocated to test and control groups, receiving OCB or TC debridement, respectively. Treatment was performed at baseline and three months. PPD, BI, and Plaque index (PI) were measured at six sites per implant and recorded by five blinded examiners at baseline, one, three, and six month(s). Pus was recorded as present/not present. Changes in PPD and BI were compared between groups and analysed using multilevel partial ordinal and linear regression., Results: Thirty-eight patients completed the study. Both groups showed significant reductions in PPD and BI at six months compared with baseline (p < .05). There was no statistically significant difference in PPD and BI changes between the groups. Eradication of peri-implant disease as defined was observed in 9.5% of cases in the OCB group and 5.9% in the TC group., Conclusions: Within the limitations of this six-month multicentre clinical trial, non-surgical treatment of peri-implantitis with OCB and TC showed no difference between the interventions. Eradication of disease was not predictable for any of the groups., (© 2022 The Authors. Clinical Oral Implants Research published by John Wiley & Sons Ltd.)

Objectives: The aim of this study was to compare periapical status transitions in teeth after post placement compared with other post-endodontic treatments in root-filled teeth., Material and Methods: This retrospective longitudinal radiographic study included radiographs of 284 patients with root filled and restored teeth with composite fillings (Endo-fill group, n  = 100), crown or fixed prosthesis (Endo-crown group, n  = 82) or post and core restorations (Endo-post group, n  = 102). All post and core restorations were made of gold alloy. The radiographs taken at the end of endodontic treatment, at the end of post-endodontic treatment and at least 8 months after post-endodontic treatment were evaluated. Post-operative periapical status was assessed according to the periapical index (PAI) and all teeth included in the study had no apical periodontitis preoperatively. Multi-state Markov analysis was used to assess periapical status transitions among the treatment groups., Results: Of 284 root-filled teeth without apical periodontitis at baseline, 7.7% developed clear apical pathology within a minimum of 8 months observational period. In the Endo-post group 11 (10.78%) teeth transited from Healthy (PAI 1) to Disease (PAI 2-4) state compared with eight (9.75%) in the Endo-crown group and four (4%) in the Endo-fill group. The transition probabilities from Healthy (PAI 1) to Mild diseased (PAI 2) were 17.5% in the Endo-post group, 13.1% in the Endo-crown group and 5.3% in the Endo-fill group. Multivariate analysis showed that teeth in the Endo-fill group had 60% lower hazard to transit from Healthy (PAI 1) to Mild diseased (PAI 2) state [HR 0.40; 95% CI 0.12, 0.94]. A period exceeding 8 months between the end of the endodontic treatment and prosthetic treatment significantly increased the hazard of disease progression by three times compared with a period of ≤8 months [HR 3.16; 95% CI 1.06, 9.42]., Conclusions: Teeth without radiographic lesions at baseline and restored with posts had higher hazard to transit from healthy to diseased periapical status compared with teeth restored with composite restorations. Controlled clinical trials with longer follow-up periods are needed to validate these findings.

Introduction: This study evaluated the bacterial reduction promoted by root canal preparation using irrigation with sodium hypochlorite (NaOCl) alone, associated with etidronic acid (1-hydroxyethane 1,1-diphosphonic acid [HEDP]) or alternated with citric acid, and after a supplementary agitation step., Methods: Extracted mandibular premolars were selected and distributed into 3 groups based on anatomically paired micro-computed tomographic analyses. The canals were contaminated with Enterococcus faecalis for 30 days and then subjected to chemomechanical preparation with a reciprocating instrument under irrigation with NaOCl alone, mixed with HEDP (NaOCl/HEDP), or alternated with citric acid (NaOCl/CA). A supplementary agitation step with the XP-endo Finisher was performed in all groups. Intracanal bacteriological samples were taken before (S1) and after preparation (S2) and after the supplementary approach (S3). DNA was extracted from the samples and subjected to quantitative real-time polymerase chain reaction., Results: Intragroup analyses revealed a substantial bacterial reduction from S1 to S2 or S3 in all groups (P < .01). The supplementary agitation resulted in S2-to-S3 bacterial reduction of 6%, 68%, and 80% in the NaOCl, NaOCl/HEDP, and NaOCl/CA groups, respectively. Irrigation with NaOCl alone resulted in 53% and 47% of samples negative for bacteria in S2 and S3, respectively. Corresponding figures for NaOCl/HEDP were 75% and 85%, and 44% and 72% for NaOCl/CA. Intergroup analyses of S2 samples showed that NaOCl/HEDP was significantly more effective than the other 2 in reducing the bacterial levels (P < .05). After the supplementary approach, both NaOCl/HEDP and NaOCl/CA were significantly more effective than NaOCl alone (P < .05), with no significant differences between them (P > .05)., Conclusions: Both the freshly combined NaOCl/HEDP solution and the alternate use of NaOCl and citric acid followed by XP-endo Finisher agitation resulted in significantly higher intracanal bacterial reduction than NaOCl alone., (Copyright © 2022 American Association of Endodontists.

Background: Dietary diversity scores can be used as a proxy for dietary intakes and for assessment of nutrient adequacy. Studies from low-resource settings have found maternal dietary diversity scores to be associated with neonatal birth size. We here investigated the relationship between the dietary diversity score among pregnant mothers and birth size of their offspring across quantiles of the birth size variables; birth weight, length, abdominal circumference, and head circumference. We also investigated if seasonality affects birth size across different quantiles., Methods: Dietary intake and anthropometric data were collected from 190 pregnant women and their neonates in rural Malawi through two agricultural seasons. Dietary data was collected using 24-hour recall interviews and was categorized into the 10-food group dietary diversity score proposed for women by the Food and Agriculture Organization. Neonatal anthropometrics were collected upon delivery at health facilities. Quantile regression analyses were used to investigate associations between dietary diversity scores and birth size, as well as between seasonality and birth size., Results: We found that neonatal abdominal circumference was 0.9 cm larger during the post-harvest season compared to the pre-harvest season among neonates in the 25th quantile. Birth weight was 281.4 g higher for those born during the post-harvest season in the 90th quantile. For a one-unit increase in maternal dietary diversity score, birth weight increased by 56.7 g among those in the 25th quantile and neonatal head circumference increased by 0.2 cm for those in the 70th quantile. However, these findings did not remain significant when considering the cluster effect of the neonatal anthropometric data., Conclusions: Our findings indicate that the relationship between seasonality and birth size differs across the distribution of birth size. Investigating the effect of seasonality across the distribution of birth size could be important to identify vulnerable subgroups and develop better, targeted interventions to improve maternal and child nutrition and health., (© 2022.

Introduction: National violence against children (VAC) surveys in Tanzania and Kenya reported that approximately three-quarters of children in Tanzania experienced physical violence while 45.9% of women and 56.1% of men experienced childhood violence in Kenya. In response to VAC, Investing in Children and their Societies-Strengthening Families & Protecting Children (ICS-SP) developed the whole school approach (WSA) for reducing VAC in and around schools. Objectives of this evaluation are to: (1) determine intervention's feasibility and (2) the extent to which the WSA reduces prevalence and incidence of VAC in and around schools in Kenya and Tanzania; (3) gain insights into changes in stakeholders' knowledge, attitudes and practices in relation to VAC following intervention implementation and (4) provide evidence-based recommendations for refining intervention content, delivery and theory of change (ToC)., Methods and Analysis: The study is a mixed-methods, controlled before-and-after, quasi experimental pilot designed to assess the delivery and potential changes in knowledge, attitudes, behaviours and VAC prevalence and incidence in and around schools following the WSA intervention implementation in Kenya and Tanzania. The preintervention phase will entail stakeholder enhancement of the WSA ToC and baseline cross-sectional surveys of teaching and non-teaching staff and parents (knowledge, attitude and practices), pupils (VAC incidents and school climate) and school safety audits. The WSA intervention implementation phase will include an intervention delivery process assessment and random school visits. In the postintervention phase, end-line surveys will be conducted similarly to baseline. Focus group discussions and in-depth interviews will be held with ICS-SP staff, training facilitators, teachers, parents and pupils to gain insights into acceptability, delivery and potential intervention effects. Quantitative and qualitative data will be analysed using SPSS V.25 and NVIVO V.12, respectively., Ethics and Dissemination: Ethics approvals were received from Amref Health Africa in Kenya (AMREF-ESRC P910/2020) and National Health Research Ethics Committee (NatHREC) in Tanzania (NIMR/HQ/R.8a/Vol.IX/3655). Dissemination will be through research reports., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022. Re-use permitted under CC BY-NC.

Objectives: In this study, we present data from a neurosurgical training program in Tanzania for the treatment of pediatric hydrocephalus. The objectives of the study were to identify the demographics and clinical characteristics of pediatric patients with hydrocephalus who were admitted to Bugando Medical Centre in Mwanza, Tanzania, as well as to describe their surgical treatment and early clinical outcomes., Methods: This cross-sectional study included 38 pediatric patients. Physical examinations were conducted pre- and postoperatively, and their mothers completed a questionnaire providing demographic and clinical characteristics., Results: There was a slight preponderance of male sex (21/38; 55.3%) with median age at the time of admission of 98.5 days. The majority of patients were surgically treated (33/38; 86.8%). Among those surgically treated, most received a ventriculoperitoneal shunt (23/33; 69.7%), whereas 7 were treated with an endoscopic third ventriculostomy (7/33; 21.2%). At the time of admission, the majority of patients (86%) had head circumferences that met criteria for macrocephaly. The median time between admission and surgery was 23 days (2-49 days). Overall, 5 patients (13.2%) died, including 2 who did not receive surgical intervention., Conclusions: We found that in our population, pediatric patients with hydrocephalus often present late for treatment with additional significant delays prior to receiving any surgical intervention. Five patients died, of whom 2 had not undergone surgery. Our study reinforces that targeted investments in clinical services are needed to enable access to care, improve surgical capacity, and alleviate the burden of neurosurgical disease from pediatric hydrocephalus in sub-Saharan Africa., (Copyright © 2022 The Author(s).

Individuals with disabilities are particularly vulnerable in conflict settings, and a high rate of psychopathology is well documented among persons with disabilities. The objective of this study was to explore the change in disability prevalence among IDPs in two settlement areas in central Sudan and the association between disability and psychological distress. In this one-year follow-up study, 1549 IDPs were interviewed twice using the General Health Questionnaire (GHQ) to investigate emotional distress. Disability was measured using the Washington Group Short Set. Households were randomly selected using the community health center as the starting point. All household members above eighteen years of age in the sampled households were interviewed. There is an increase in disability prevalence among internally displaced persons over time, associated with rural residency and poverty, low education, unemployment, IDP status, originating from western Sudan, young age, male gender, and being married. Disability was further found to be associated with psychological distress. Disability among displaced persons should be considered as a risk factor for increase in psychopathological disorders and is closely related to poverty. The study is limited to individual-level data and does not incorporate relevant environmental variables that may have influenced the changes in disability rates.

Background: To describe ethnic differences in concentrations of lipids and lipoproteins, and their changes, during pregnancy to postpartum., Methods: This was a population-based cohort study conducted in primary antenatal care in Norway. The participants (n = 806) were healthy, pregnant women, 59% were ethnic minorities. Outcomes were triglycerides, total cholesterol, HDL- and LDL-cholesterol, analysed from fasting blood samples drawn at gestational age (weeks) 15, 28 and 14 weeks postpartum. We performed linear regression models and linear mixed models to explore the total effect of ethnicity on the outcomes, adjusting for gestational age /week postpartum, maternal age and education. The analyses are corrected for multiple testing using the Bonferroni correction., Results: At gestational age 15, triglyceride concentrations were lower in women of African origin (1.03 mmol/mol (95% CI: 0.90, 1.16)) and higher in women of South Asian (primarily Pakistan and Sri Lanka) origin (1.42 mmol/mol (1.35, 1.49)) and East Asian (primarily Vietnam, Philippines and Thailand) origin (1.58 mmol/mol (1.43, 1.73)) compared with Western Europeans (1.26 mmol/mol (1.20, 1.32)). Women of Asian and African origin had a smaller increase in triglycerides, LDL- and total cholesterol from gestational age 15 to 28. At gestational age 28, LDL-cholesterol levels were lowest among East Asians (3.03 mmol/mol (2.72, 3.34)) compared with Western Europeans (3.62 mmol/mol (3.50, 3.74)). Triglycerides and HDL-cholesterol were lower postpartum than at gestational age 15 in all groups, but the concentration of LDL-cholesterol was higher, except in Africans. South and East Asian women had lower HDL-cholesterol and higher triglycerides postpartum, while African women had lower triglycerides than Western Europeans., Conclusion: We found significant differences in the concentrations of lipids and lipoproteins and their changes during pregnancy and the early postpartum period related to ethnic origin., (© 2022.

Introduction: Research suggests that current care for shoulder pain is not in line with the best available evidence. This project aims to assess the effectiveness, cost-effectiveness and the implementation of an evidence-based guideline for shoulder pain in general practice in Norway., Methods and Analysis: A stepped-wedge, cluster-randomised trial with a hybrid design assessing clinical effectiveness, cost-effectiveness and the effect of the implementation strategy of a guideline-based intervention in general practice. We will recruit at least 36 general practitioners (GPs) and randomise the time of cross-over from treatment as usual to the implemented intervention. The intervention includes an educational outreach visit to the GPs, a computerised decision tool for GPs and a self-management application for patients. We will measure outcomes at patient and GP levels using self-report questionnaires, focus group interviews and register based data. The primary outcome measure is the patient-reported Shoulder Pain and Disability Index measured at 12 weeks. Secondary outcomes include the EuroQol Quality of Life Measure (EQ5D-5L), direct and indirect costs, patient's global perceived effect of treatment outcome, Pain Self-Efficacy and Brief Illness Perception Questionnaire. We will evaluate the implementation process with focus on adherence to guideline treatment. We will do a cost-minimisation analysis based on direct and selected indirect costs and a cost-utility analysis based on EQ5D-5L. We will use mixed effect models to analyse primary and secondary outcomes., Ethics and Dissemination: Ethics approval was granted by the Regional Committee for Medical and Health Research Ethics-South East Norway (ref. no: 2019/104). Trial results will be submitted for publication in a peer-reviewed medical journal in accordance with Consolidated Standards of Reporting Trials., Trial Registration Number: NCT04806191., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background and Aims: Cardiovascular diseases (CVDs) are the leading cause of death globally and in Brazil. Evidence suggests that the risk of CVDs differs by race/ethnicity. Scarce information exists about the association between CVD risk, obesity indicators and sociodemographic characteristics in the Brazilian population. Objectives: We aimed to assess the CVD risk following the Framingham risk score in relation to the population's sociodemographic profile. Further, we examined the association between anthropometric markers and risk of CVDs. Methods: A total of 701 subjects aged ≥20 years from North-eastern Brazil were recruited randomly to participate in a population-based, cross-sectional survey. Age-adjusted data for CVD risk, sociodemographic characteristics, and anthropometric indices were assessed, and their relationships examined. Results: High CVD risk (Framingham risk score ≥10%) was observed in 18.9% of the population. Males (31.9 vs. 12.5%) and older subjects (age ≥45 years: 68.9% vs. age <45 years: 4.2%) had significantly higher risk of CVDs, whereas those employed in manual labor showed lower risk (7.6 vs. 21.7%). Central obesity measures like waist-to-hip ratio and waist-to-height ratio were more strongly associated with predicted CVD risk than body mass index. Conclusions: Our population had a high risk of CVDs using the Framingham risk score. Cost-effective strategies for screening, prevention and treatment of CVDs may likely reduce disease burden and health expenditure in Brazil. Central obesity measures were strongly associated with predicted CVD risk and might be useful in the clinical assessment of patients. Follow-up studies are warranted to validate our findings., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Moreira, Mdala, Hussain, Bhowmik, Siddiquee, Fernandes, Montenegro and Meyer.)

Background: In many sub-Saharan African countries, such as Malawi, antenatal care (ANC) services do not deliver sufficient nutrition awareness to improve adequate dietary intake in pregnancy. We therefore compared the effects of supplementary nutrition education and dietary counselling with routine ANC service on nutrition knowledge and dietary intakes among Malawian pregnant women., Methods: We used data from a two-armed cluster randomised controlled trial (RCT) of which the intervention group received supplementary nutrition education, dietary counselling and routine ANC services whereas the controls received only routine ANC services. The RCT was conducted in 10 control and 10 intervention villages in Mangochi, Southern Malawi and included pregnant women between their 9 th and 16 th gestational weeks. We examined the changes in nutrition knowledge and dietary diversity from enrolment (baseline) to study end-point of the RCT (two weeks before expected delivery). We used three linear multilevel regression models with random effects at village level (cluster) to examine the associations between indicators of nutrition knowledge and diet consumption adjusted for selected explanatory variables., Results: Among 257 pregnant women enrolled to the RCT, 195 (76%) were available for the current study. The supplementary nutrition education and counselling led to significant improvements in nutrition knowledge, dietary diversity and nutrition behaviour in the intervention group compared with controls. Most women from both study groups had a moderate consumption of diversified foods at study end-point. A significant positive association between nutrition knowledge and consumption of a diversified diet was only observed in the intervention group., Conclusions: Nutrition knowledge and dietary diversity improved in both study groups, but higher in the intervention group. Increased nutrition knowledge was associated with improved dietary diversity only in the intervention women, who also improved their nutrition perceptions and behaviour. Antenatal nutrition education needs strengthening to improve dietary intakes in pregnancy in this low resource-setting., Trial Registration: Clinical trials.gov ID: NCT03136393 (registered on 02/05/2017)., (© 2021.

Aims: To explore whether the general practitioners' (GPs') performance of recommended processes of care was associated with estimated risk of cardiovascular disease (CVD) and poor glycaemic control in patients with type 2 diabetes., Methods: A cross-sectional study from Norwegian general practice including 6015 people with type 2 diabetes <75 years old, without CVD and their 275 GPs. The GPs were split into quintiles based on each GP's average performance of six recommended processes of care. The quintiles were the exposure variable in multilevel regression models with 10-year risk of cardiovascular events estimated by NORRISK 2 (total and modifiable fraction) and poor glycaemic control (HbA 1c >69 mmol/mol (>8.5%)) as outcome variables., Results: The mean total and modifiable estimated 10-year CVD risk was 12.3% and 3.3%, respectively. Compared with patients of GPs in the highest-performing quintile, patients treated by GPs in the lowest quintile had an adjusted total and modifiable CVD risk that was 1.88 (95% CI 1.17-2.60) and 1.78 (1.14-2.41) percent point higher. This represents a relative mean difference of 16.6% higher total and 74.8% higher modifiable risk among patients of GPs in the lowest compared with the highest quintile. For patients with GPs in the lowest-performing quintile, the adjusted odds of poor glycaemic control was 1.77 (1.27-2.46) times higher than that for patients with a GP in the highest quintile., Conclusions: We found a pattern of lower CVD risk and better glycaemic control in patients of GPs performing more recommended diabetes processes of care., (© 2021 The Authors.

Aims: To identify individual and general practitioner (GP) characteristics associated with potential over- and undertreatment of hyperglycaemia in type 2 diabetes and with HbA 1c not being measured., Methods: A cross-sectional study that included 10233 individuals with type 2 diabetes attending 282 GPs. Individuals with an HbA 1c measurement during the last 15 months were categorized as potentially overtreated if they were prescribed a sulphonylurea and/or insulin when the HbA 1c was less than 53 mmol/mol (7%) when aged over 75 years or less than 48 mmol/mol (6.5%) when aged between 65 and 75 years. Potential undertreatment was defined as age less than 60 years and HbA 1c > 64 mmol/mol (8.0%) or HbA 1c > 69 mmol/mol (8.5%) and treated with lifestyle modification and/or monotherapy. We used multilevel binary and multinominal logistic regression models to examine associations., Results: Overall, 4.1% were potentially overtreated, 7.8% were potentially undertreated and 11% did not have HbA 1c measured. Characteristics associated with potential overtreatment were as follows: long diabetes duration, prescribed antihypertensive medication, cardiovascular disease and renal failure. Potential undertreatment was associated with male gender, non-western origin and low educational level. Characteristics associated with not having an HbA 1c measurement performed were male gender, age < 50 years and cardiovascular diseases. GP specialist status and GPs' use of a Noklus diabetes application reduced the risk of not having an HbA 1c measurement performed., Conclusion: Potential overtreatment in elderly individuals with type 2 diabetes was relatively low. Nevertheless, appropriate de-intensification or intensification of treatment and regular HbA 1c measurement in identified subgroups is warranted., (© 2020 The Authors.

Aims: To explore variation in general practitioners' (GPs') performance of six recommended procedures in type 2 diabetes patients <75 years without cardiovascular disease., Methods: Cross-sectional study of quality of diabetes care in Norway based on electronic health records from 2014. GPs (clustered in practices) were divided in quintiles based on a composite measure of performance of six processes of care. We fitted a multilevel partial ordinal regression model to identify GP factors associated with being in quintiles with better performance., Results: We identified 6015 type 2 diabetes patients from 275 GPs in 77 practices. The GPs performed on average 63.4% of the procedures; on average 46% in the poorest quintile to 81% in the best quintile with a larger range in individual GPs. After adjustments, use of a structured follow-up form was associated with GPs being in upper three quintiles (OR 12.4 (95% CI 2.37-65.1). Routines for reminders were associated with being in a better quintile (OR 2.6 (1.37-4.92). GPs' age >60 years and heavier workload were associated with poorer performance., Conclusion: We found large variations in GPs' performance of processes of care. Factors reflecting structure and workload were strongly associated with performance., (Copyright © 2020 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Objective: To describe self-reported symptoms among patients in general practice and to explore the relationships between symptoms experienced by patients and diagnoses given by general practitioners., Design: Doctor-patient questionnaires focusing on patients' self-reported symptoms during the past 7 days and the doctors' diagnoses., Setting: General practices in urban and suburban areas in Southeast Norway., Subjects: Forty-seven general practitioners who included 866 patients aged ≥18 years on a random day in practice., Results: The most frequently reported symptoms were tiredness (46%), lower back pain (43%), neck pain (41%), headache (39%), shoulder pain (36%), and sleep problems (35%). Women had a significantly higher prevalence than men for 16 of 38 symptoms ( p  < 0.05). The mean number of symptoms was 7.5 (range, 0-32; women, 8.1; men, 6.5, p  < 0.05). Regression analysis showed that patients who received a social security grant had 59% more symptoms than those who were employed and that people with asthenia and depression/anxiety had 44% and 23% more symptoms, respectively than those with all other diagnoses. The patterns of symptoms reported showed similar patterns across the five most prevalent diagnoses., Conclusions: Patients in general practice report a number of symptoms and share a common pattern of symptoms, which appear to be partly independent of the diagnoses given. These findings suggest that symptoms are not necessarily an indication of disease.KEY POINTSPatients consulting general practitioners have a high number of self-reported symptoms.The most frequent symptoms are tiredness, lower back pain, neck pain, headache, shoulder pain, and sleep problems.Patients diagnosed with asthenia and depression/anxiety report the highest number of symptoms.Selected diagnoses show similar patterns in symptom distribution.Symptoms are not necessarily an indication of disease.

Introduction: This ex vivo study compared the disinfection and shaping abilities of 2 preparation protocols in C-shaped canals., Methods: Mandibular second molars with type I C-shaped canals were pair matched based on micro-computed tomographic (micro-CT) analysis and distributed into 2 groups. The canals were contaminated with a mixed bacterial culture and prepared using 2 protocols, both with 2.5% sodium hypochlorite irrigation: XP-endo Shaper (FKG Dentaire, La Chaux-de-Fonds, Switzerland) supplemented with XP-endo Finisher (FKG Dentaire) (XP-E) and BioRaCe (FKG Dentaire) supplemented with a Hedström file (Dentsply/Sirona, Tulsa, OK) (BR-Hed). Micro-CT scans and intracanal bacteriologic samples were taken before (scan #1 and sample 1) and after preparation (scan #2 and sample 2) and after the supplementary step (scan #3 and sample 3). Canal shaping was evaluated by micro-CT imaging, and disinfection was assessed by quantitative polymerase chain reaction., Results: Micro-CT data from the XP-E (n = 21) and BR-Hed (n = 23) protocols revealed no significant differences between groups regarding shaping parameters (canal volume, surface area, structure model index, and prepared walls) after preparation and after the supplementary step (P > .05). All these parameters significantly increased after each preparation step (P < .05), except for structure model index changes after the XP-endo Finisher (P > .05). Bacteriologic data from the XP-E (n = 21) and BR-Hed (n = 22) groups showed that 14 (66.7%) and 10 (45.5%) S2 samples still had detectable bacteria, respectively. The corresponding figures for supplementary steps with the XP-endo Finisher and Hedström file were 11 (52.4%) and 10 (45.5%), respectively. Bacterial counts in sample 1 significantly decreased in samples 2 and 3 in both groups (P < .01). Intragroup comparison between sample 2 and sample 3 showed a 66% reduction in counts after using the Hedström file and 18% after using the XP-endo Finisher (P > .05 for both groups).
