Chronic hepatitis B virus (HBV) infection is a major risk factor for hepatocellular carcinoma (HCC), and surveillance is recommended for patients without cirrhosis when risk exceeds an incidence rate (IR) of 0.2%. Populations in Asia and sub‐Saharan Africa have been associated with HCC at younger ages, but the risk after immigration to Western countries should be investigated. The aim of this study was to study HCC by age and country of origin in people with chronic HBV infection in Sweden. Through national registers, residents with chronic HBV diagnosis (1990–2015) were identified with information on country of origin, immigration/emigration, death, coinfections, antiviral therapy, and HCC. Observation time started at HBV diagnosis, and IR and hazard ratios for HCC were calculated by sex, age, and region of origin. Among 16,410 individuals (47% women), the origin and observation time (person years) were as follows: Western Europe, 2316 (25,415); Eastern Europe, 2349 (26,237); Middle East/North Africa, 4402 (47,320); sub‐Saharan Africa, 3677 (30,565); Asia, 3537 (35,358); and other, 129 (1277). There were 232 individuals with HCC (82% in men). The IR increased with age and exceeded 0.2% for Asian men from age group 40–49 years (IR, 0.63; 95% confidence interval, 0.39–1.00), for men of other origins from age group 50–59 years, and for women aged ≥60 years originating from Eastern Europe, Asia, and Middle East/North Africa. After exclusion of patients with cirrhosis or HBV treatment, the IR still exceeded 0.2% in Asian men aged 40–49 years. This study demonstrates that HBV‐infected men of Asian origin should be recommended HCC surveillance at younger ages, but there is a need for further studies of HCC incidence in African‐born men without cirrhosis living in the Western world.

Objectives: It is well known that oral health status is associated with oral health‐related quality of life (OHRQoL) in the general population. The aim of this study was to describe and analyse OHRQoL among older people in short‐term care and its associated factors. Materials and Methods: This cross‐sectional study included 391 older people in 36 short‐term care units. Data were collected via clinical oral assessments, questions about self‐perceived oral and general health, Katz Index of Activities of Daily Living (Katz‐ADL) and the Revised Oral Assessment Guide (ROAG). OHRQoL was measured using the Oral Health Impact Profile (OHIP‐14). Multivariate logistic regression models were applied in the analysis. Results: Poor OHRQoL was reported by 34% of the older people. Associated factors were swallowing problems according to ROAG; quite poor/poor self‐perceived physical, psychological and oral health; and being a woman. Conclusions: There is an association between OHRQoL and older people's self‐perceived health according to the OHIP‐14. This indicates the importance of early detection of oral health problems in frail older people and to assess both oral health and swallowing problems among older people in short‐term care.

While overweight among adults has been linked with renal cell carcinoma (RCC) risk, little is known about the potential influence of overweight and obesity during adolescence. To ascertain if adolescent body mass index is associated with subsequent risk of RCC, we identified a cohort of 238,788 Swedish men who underwent mandatory military conscription assessment between 1969 and 1976 at a mean age of 18.5 years. At the time of conscription assessment, physical and psychological tests were performed including measurements of height and weight. Participants were followed through linkage to the Swedish Cancer Registry to identify incident diagnoses of RCC. The association between body mass index (BMI, kg/m2) at conscription assessment and subsequent RCC was evaluated using multivariable Cox regression. During a follow‐up of up to 37 years, 266 men were diagnosed with RCC. We observed a trend for higher RCC risk with increasing BMI during adolescence, where one‐unit increase in BMI conferred a 6% increased risk of RCC (95% CI 1.01–1.10). compared to normal weight men (BMI 18.5‐ < 25), men with overweight (BMI 25‐ < 30) or obesity (BMI ≥30) had hazard ratios for RCC of 1.76 (95% CI 1.16–2.67) and 2.87 (95% CI 1.26–6.25), respectively. The link between overweight/obesity and RCC appear to be already established during late adolescence. Prevention of unhealthy weight gain during childhood and adolescence may thus be a target in efforts to decrease the burden of RCC in the adult population. What's new? While overweight among adults has been linked with renal cell carcinoma risk, little is known about the potential influence of overweight and obesity during adolescence. This large prospective cohort study over more than 35 years suggests that the link between overweight/obesity—alone and in combination with low physical working capacity—and renal cell carcinoma is already established in late adolescence. Prevention of unhealthy weight gain during childhood and adolescence may thus be a target in efforts to decrease the burden of renal cell carcinoma in the adult population. [ABSTRACT FROM AUTHOR]

Background: Oral health is important for well‐being and overall health. Older peoples′ oral health is well described in the residential care context, but remains understudied in short‐term care. Objective: The aim of this study was to describe oral health, daily oral care and related factors among older people in short‐term care and to compare self‐perceived oral health with professional assessment. Materials and methods: This cross‐sectional study included 391 older people in 36 short‐term units in 19 Swedish municipalities. Oral health was assessed professionally by clinical oral assessment and the Revised Oral Assessment Guide (ROAG). The older peoples' perceptions of their own oral health were measured with a global question on self‐perceived oral health. Self‐care ability was assessed with Katz Index of Activities of Daily Living (Katz‐ADL). Results: Mean age was 82.9 years, 19% of participants were totally edentulous, and 43% had ≥20 teeth. Almost 60% had coating or food debris on their teeth, but only 19% received help with daily oral care. Those who were dependent on help with self‐care had around a sixfold higher risk of having oral problems. There was a low level of agreement between the clinical assessment based on ROAG and self‐perceived oral health. Conclusion: Professionals' assessments of oral health differed considerably from the older peoples′ own assessments. A higher risk of oral problems and more occurrence of coating or food debris or broken teeth were seen among those dependent on help with self‐care (ADL). This study indicates that in order to improve older peoples′ oral health and oral care we need to provide person‐centred oral care and to develop a close collaboration between nursing and dental staff.

Objective: The present study aims to gain knowledge about the dentist's use and choice of digital extraoral imaging methods, panoramic radiography and cone beam computed tomography (CBCT).Materials and Methods: A questionnaire sent to 2481 dentists within the Swedish Dental Society contained questions about the panoramic technique and CBCT technique used, education, clinic size and type of service. The response rate was 53%.Results: The study showed that 61% of the Swedish dentists had access to panoramic techniques and that 84% used a direct digital sensor, while 6% used storage phosphor plate techniques. Around 8% of the Swedish dentists had access to CBCT. It was also observed that group practices had two times higher odds of having panoramic equipment compared with solo practices. Approximately 40% of the dentists had undergone postgraduate education in oral radiology during the last 5 years. Dental nurses and dental hygienists exposed 92% of the panoramic radiographs and 75% of the CBCTs. Thirty per cent of those clinics with access to a panoramic unit exposed >30 panoramic radiographs per month and 56% of the clinics having access to CBCT did more than 75 examinations per year.Conclusions: Today 61% of Swedish dentists have access to panoramic radiography and 8% have access to CBCT. There is a greater likelihood of having access if the dentist works in the public dental health service or in a group practice and if the dentist has undergone any postgraduate course in oral radiology.

About 90% are immigrants from HBV-endemic areas, approximately as many people from East/Southeast Asia, sub-Saharan Africa, Greater Middle East, and Europe (including Sweden). We thank Dr. Singh and Dr. Mondia for their interest in our study on the risk of hepatocellular carcinoma (HCC) by age and country of origin in people with chronic hepatitis B virus (HBV) infection living in Sweden. Therefore, we wanted to study and compare the incidence of HCC by age and country of origin in people with chronic HBV infection in Sweden. [Extracted from the article]

Objective: The present study aims to gain knowledge about the dentist's use and choice of digital intraoral imaging methods.Materials and Methods: A questionnaire sent to 2481 dentists within the Swedish Dental Society contained questions about the type of X-ray technique used, problems experienced with digital radiography, and reasons for choosing digital technology, and about indications, clinic size and type of service. Response rate was 53%.Results: Ninety-eight percent of the dentists had made the transition to digital radiography; only 2% used film technique, and solid-state detector (SSD) was the most used digital technique. More years in service decreases the likelihood of applying individual indications for performing a full mouth examination. More retakes were done with SSDs compared to storage phosphor plates. Reasons for choosing digital techniques were that work was easier and communication with the patients improved. However, dentists also experienced problems with digital techniques, such as exposure and projection errors and inadequate image quality. The Swedish Radiation Safety Authority states that all radiological examinations should be justified, something not always followed.Conclusions: This study showed that 98% of the respondents, Swedish dentists within the Swedish Dental Society, used digital techniques, and the most used was the solid-state technique.

• To our knowledge, this is the first nationwide population-based study describing the incidence of PML in natalizumab treated patients. • Since 2013 there has been only one case of PML during NTZ treatment in Sweden. • The PML incidence 2018 in Sweden and globally was 0.7 and 4.15 per 1,000 person years, respectively. • The Swedish nationwide PML risk surveillance program seemed to have reduced the PML incidence. Natalizumab (NTZ) treatment of multiple sclerosis (MS) has been associated with increased risk of progressive multifocal leukoencephalopathy (PML). The aim of the present study was to evaluate the impact of PML risk assessment on PML incidence in NTZ treated MS patients. By using information from the population-based Swedish MS registry a retrospective cohort was established of patients treated with NTZ between 2006-2018. The effect on PML incidence before and after utilizing a risk management plan, including JC virus (JCV) serology, was analyzed. In December 2018, 804 PML cases associated with NTZ therapy of MS had been reported globally, including 9 cases from Sweden. The estimated PML incidence 2018 in Sweden and globally was 0.7 (0.3-1.4) and 4.15 (3.9-4.4) per 1,000 person years, respectively. In Sweden, JCV serology was introduced 2012 for PML risk assessment and the cumulative risk of PML was significantly lower 2012-2018 compared to the period 2006-2011 (p=0.042). The mean NTZ exposure time was 60.1 months (SD 37.2) in the first period (2006-2011) and 32.6 months (SD 22.0) in the second period (2012-2018). The number of patients treated with NTZ decreased, and the number of patients at increased risk of PML was 1.9 % at the end of the study period. Since 2006 the incidence of PML associated with NTZ treatment of MS has decreased in Sweden. Our findings suggest that this reduction is due to an effective adoptation and adherence to the established risk management plan that implies switching patients at increased PML risk from NTZ to other highly efficacious therapies. A less pronounced decline in PML incidence has recently been observed in France, but not globally. [ABSTRACT FROM AUTHOR]
