Regional Perspectives on Complementary and Alternative Medicine: Results of a Regional Survey.

BACKGROUND: Complementary and alternative medicine (CAM) is widely used by patients with cancer. Research indicates that the use of CAM is more prevalent in rural areas compared to urban areas. There is currently a lack of information regarding the scope and specifics of CAM use among patients in Sweden, particularly in rural areas. The aim of this study was to estimate the extent and characteristics of CAM use among cancer patients in the rural areas of Region Gävleborg. METHODS: A total of 631 questionnaires were sent out, and 376 of those were returned, corresponding to a response rate of 59.6%. Oncology patients received questionnaires at their initial appointment for curative care at Gävle Hospital's Department of Oncology. When enrolling in palliative outpatient care in their homes, palliative patients were sought out. Standard descriptive statistics were used to present the characteristics of the respondents. To determine odds ratios and potential factors (age, gender, diagnosis, and education) affecting CAM use after cancer diagnosis, a multivariable logistic model was constructed. RESULTS: Based on clinical observations, the authors' hypothesis that CAM use is particularly common in small towns in the Hälsingland region was verified in this study. This was particularly pronounced among younger people and residents of small towns in the province of Halsingland. The higher level of CAM use appears to apply to both men and women. CONCLUSIONS: CAM appears to be used more frequently by patients residing in rural areas. It is crucial that care providers enquire about all of the patient's health-seeking activities. Further research is needed on the usage of CAM in rural areas and the potential cultural influences contributing to CAM use. From a sociological standpoint, it is crucial to draw attention to the fact that CAM use may be more prevalent in certain rural areas, particularly in centralized societies where it is more difficult to access healthcare in remote regions.

Use of CAM among cancer patients : Results of a regional survey in Sweden.

BACKGROUND: The use of complementary and alternative medicine (CAM) by patients is widespread. However, there is a lack of knowledge regarding the extent and details of patient CAM use in Sweden, especially in rural Sweden. The aim of this study was to estimate the extent and characteristics of CAM use among cancer patients in Region Gävleborg. METHODS: A total of 631 questionnaires were distributed to which 376 responses were registered, yielding a response rate of 59.6%. Questionnaires were distributed to oncology patients at their first visit for curative treatment at the Department of Oncology, Gävle Hospital. Palliative patients were recruited at their first visit and during enrollment in palliative outpatient care in their own homes. The characteristics of the respondents were presented with standard descriptive statistics. A multivariable logistic model was fitted to calculate odds ratios (ORs) and identify potential predictors (Age, Gender, Education, Diagnosis) of CAM use post-cancer diagnosis. RESULTS: 54% of all participants reported lifetime CAM use, 34% reported CAM use post-diagnosis. The most common CAM methods used after diagnosis are vitamins, health food preparations, herbal teas, prayer and dietary methods. The most common source of information reported is family and friends. Almost 70% of those who used CAM after their diagnosis stated that they did not discuss their use with healthcare professionals. Most patients reported that they would like some CAM modalities to be offered within conventional care regardless of their own CAM use. CONCLUSIONS: The use of CAM is common among patients with cancer in the region of Gävleborg, and previous studies show a similar use in Sweden in general. Based on the widespread use of CAM and patient interest in discussing CAM use with healthcare professionals, greater attention and focus should be placed on creating a basis for this dialogue. If we, as healthcare professionals, are to emphasise our commitment to providing patient-centred care, we must acknowledge that patients use CAM and are seeking a dialogue about CAM use in their care.

Colorectal Cancer in Childhood-onset Inflammatory Bowel Disease: A Scandinavian Register-based Cohort Study, 1969-2017.

Through linkage of data from Danish and Swedish national registers we identified 6937 patients with childhood (<18 years)-onset Crohn disease (CD), 8514 patients with childhood-onset ulcerative colitis (UC) and up to 10 times as many matched (sex, age, residence) reference individuals 1969-2017. During follow-up to a median age of 27 (interquartile range = 21-39) years, 25 (0.36%) CD patients were diagnosed with colorectal cancer (CRC) versus 43 (0.06%) reference individuals, and 113 (1.33%) UC patients versus 45 (0.05%) reference individuals. The hazard ratio (HR) for CRC was 6.46 (95% CI = 3.95-10.6) in CD and 32.5 (95% CI = 23.0-45.9) in UC and increased with decreasing age at diagnosis. The HR for CRC was increased for all phenotypes, but with higher estimates for colonic CD [17.9 (95% CI = 7.43-43.3)] and UC with extensive/pancolitis [36.3 (95% CI = 22.8-57.8)]. The relative risk of CRC was increased for all phenotypes of childhood-onset inflammatory bowel disease. Age at onset may be considered an additional risk factor when implementing surveillance programs.

Colorectal cancer in elderly-onset inflammatory bowel disease: a 1969-2017 Scandinavian register-based cohort study.

BACKGROUND: Previous research indicates that the increased relative risk of colorectal cancer (CRC) in inflammatory bowel disease (IBD) is limited to young-onset IBD. AIM: To estimate risks of incident CRC and death from CRC in elderly-onset IBD METHODS: Patients diagnosed with IBD at age ≥ 60 years between 1969 and 2017 were identified using Danish and Swedish National Patient Registers and histopathology data. We linked data to Cancer and Causes of Death Registers and used Cox regression to estimate hazard ratios (HRs) for CRC diagnosis and death compared to matched (by sex, age, and region) IBD-free individuals. RESULTS: Among 7869 patients with Crohn's disease followed for 54,220 person-years, and 21,224 patients with ulcerative colitis (UC) followed for 142,635 person-years, 2.10% and 1.90% were diagnosed with CRC, compared to 2.26% and 2.34% of reference individuals (median follow-up 6 and 7 years). The incidence of CRC was elevated during the first year after IBD diagnosis: 4.36 (95% CI = 3.33-5.71) in Crohn's disease and 2.48 (95% CI = 2.03-3.02) in UC, but decreased after the first year of follow-up: 0.69 (95% CI = 0.56-0.86) and 0.78 (95% CI = 0.69-0.88). Once diagnosed with CRC, the risk of CRC death was similar for IBD patients and the general population. CONCLUSION: The excess risk of CRC in elderly-onset IBD was probably due to bias and not observed beyond the first year. From 2010, the HR for CRC diagnosis more than 1 year after initial IBD diagnosis was lower than in the largely unscreened reference population, supporting the benefit of endoscopic screening and surveillance in patients with IBD.

Identification of Childhood-Onset Inflammatory Bowel Disease in Swedish Healthcare Registers: A Validation Study.

Purpose: The Swedish National Patient Register (NPR) is often used in observational studies of childhood-onset inflammatory bowel disease (IBD) (<18 years of age) and its subtypes, but the validity of previously used register-based algorithms for capturing childhood-onset IBD has never been examined. Methods: We identified a random sample of 233 individuals with at least two first ever diagnostic listings of IBD in the NPR between 2002 and 2014. We calculated the test characteristics for different register-based definitions of IBD and its subtypes using the Copenhagen criteria and the revised Porto criteria as gold standard, both based on medical chart review. We made assumptions of the occurrence of undiagnosed IBD in the general child population based on available literature. Results: Out of 233 individuals with at least two diagnostic listings of IBD, 216 had true IBD, resulting in a positive predictive value (PPV) = 93% (95% confidence interval (CI) 89-96), sensitivity = 88% (95% CI 83-92), specificity = 100% (95% CI 100-100), and negative predictive value (NPV) = 100% (95% CI 100-100). The PPV for the NPR-based definitions of IBD subtypes at time of first IBD diagnosis and at end of follow-up were 78% (95% CI 69-86) and 88% (95% CI 80-94), respectively, for Crohn's disease and 74% (95% CI 63-83) and 71% (95% CI 60-80), respectively, for ulcerative colitis. Conclusion: The validity of register-based definitions of childhood-onset IBD in the Swedish NPR is high and can be used to identify patients in observational research.

Association Between Inflammatory Bowel Disease and Spondyloarthritis: Findings from a Nationwide Study in Sweden.

BACKGROUND AND AIMS: Inflammatory bowel disease [IBD] has been associated with spondyloarthritis [SpA], but population-based estimates are scarce. Here we compare the occurrence of SpA before and after a diagnosis of IBD with the general population, overall and by IBD subtype and age. METHODS: We used a nationwide register-based cohort study of 39 203 patients diagnosed with IBD during 2006-2016, identified from Swedish registers and gastrointestinal biopsy data, and 390 490 matched reference individuals from the general population. Conditional logistic regression models were used to estimate odds ratios [ORs] for a prior [prevalent] SpA diagnosis and conditional Cox regression to calculate hazard ratios [HRs] for a subsequent [incident] SpA diagnosis in IBD patients. RESULTS: IBD patients were more likely to have prevalent SpA at IBD diagnosis [2.5%] compared with reference individuals [0.7%] with an OR of 3.48 [95% CI: 3.23, 3.75]. They also more often received an incident diagnosis of SpA; during 23 341 934 person-years of follow-up in IBD patients, there were 1030 SpA events [5.0/1000 person-years] compared with 1524 SpA events in the reference group [0.72/1000 person-years], corresponding to an HR of 7.15 [95% CI: 6.60, 7.75]. In subgroup analyses, associations were most pronounced among patients with Crohn's disease ([OR = 5.20; 95% CI: 4.59, 5.89], and [HR = 10.55; 95% CI: 9.16, 12.15]) and paediatric onset IBD ([OR = 3.63; 95% CI: 2.35, 5.59] and [HR = 15.03; 95% CI: 11.01, 20.53]). CONCLUSIONS: IBD patients more frequently experience SpA both before and after the diagnosis of IBD compared with the general population, supporting evidence of a shared pathophysiology. The variation in SpA comorbidity, across IBD subtypes and age groups, calls for targeted approaches to facilitate timely diagnosis and intervention.

Increased Mortality Persists after Treatment of Cushing's Disease: A Matched Nationwide Cohort Study.

Context: Whether biochemical remission normalizes life expectancy in Cushing's disease (CD) patients remains unclear. Previous studies evaluating mortality in CD are limited by using the expected number of deaths in the background population instead of the actual number in matched controls. Objective and setting: To study mortality by time-to-event analysis in an unselected nationwide CD patient cohort. Design and participants: Longitudinal data from the Swedish Pituitary Register of 371 patients diagnosed with CD from 1991 to 2018 and information from the Swedish Cause of Death Register were evaluated. Four controls per patient (n = 1484) matched at the diagnosis date by age, sex, and residential area were included. Main outcome measures: Mortality and causes of death. Results: The median diagnosis age was 44 years (interquartile range 32-56), and the median follow-up was 10.6 years (5.7-18.0). At the 1-, 5-, 10-, 15-, and 20-year follow-ups, the remission rates were 80%, 92%, 96%, 91%, and 97%, respectively. Overall mortality was increased in CD patients compared with matched controls [hazard ratio (HR) 2.1 (95% CI 1.5-2.8)]. The HRs were 1.5 (1.02-2.2) for patients in remission at the last follow-up (n = 303), 1.7 (1.03-2.8) for those in remission after a single pituitary surgery (n = 177), and 5.6 (2.7-11.6) for those not in remission (n = 31). Cardiovascular diseases (32/66) and infections (12/66) were overrepresented causes of death. Conclusions: Mortality was increased in CD patients despite biochemical remission compared to matched controls. The study highlights the importance of careful comorbidity monitoring, regardless of remission status.

Long-term outcomes of patients with acromegaly: a report from the Swedish Pituitary Register.

OBJECTIVE: To describe the treatment and long-term outcomes of patients with acromegaly from all healthcare regions in Sweden. DESIGN AND METHODS: Analysis of prospectively reported data from the Swedish Pituitary Register of 698 patients (51% females) with acromegaly diagnosed from 1991 to 2011. The latest clinical follow-up date was December 2012, while mortality data were collected for 28.5 years until June 2019. RESULTS: The annual incidence was 3.7/million; 71% of patients had a macroadenoma, 18% had visual field defects, and 25% had at least one pituitary hormone deficiency. Eighty-two percent had pituitary surgery, 10% radiotherapy, and 39% medical treatment. At the 5- and 10-year follow-ups, insulin-like growth factor 1 levels were within the reference range in 69 and 78% of patients, respectively. In linear regression, the proportion of patients with biochemical control including adjuvant therapy at 10 years follow-up increased over time by 1.23% per year. The standardized mortality ratio (SMR) (95% CI) for all patients was 1.29 (1.11-1.49). For patients with biochemical control at the latest follow-up, SMR was not increased, neither among patients diagnosed between 1991 and 2000, SMR: 1.06 (0.85-1.33) nor between 2001 and2011, SMR: 0.87 (0.61-1.24). In contrast, non-controlled patients at the latest follow-up from both decades had elevated SMR, 1.90 (1.33-2.72) and 1.98 (1.24-3.14), respectively. CONCLUSIONS: The proportion of patients with biochemical control increased over time. Patients with biochemically controlled acromegaly have normal life expectancy, while non-controlled patients still have increased mortality. The high rate of macroadenomas and unchanged age at diagnosis illustrates the need for improvements in the management of patients with acromegaly.

Allergy-related diseases in childhood and risk for abdominal pain-related functional gastrointestinal disorders at 16 years-a birth cohort study.

BACKGROUND: Studies on allergy-related diseases in relation to abdominal pain-related functional gastrointestinal disorders (AP-FGIDs) in children are few and results are contradictory. We examined the associations between childhood allergy-related diseases and adolescent AP-FGIDs in general and irritable bowel syndrome (IBS) in particular. METHOD: Prospective population-based birth cohort study of 4089 children born in Sweden 1994-1996. We analysed data from 2949 children with complete follow-up at 16 years (y) and no diagnosis of inflammatory bowel disease or coeliac disease at 12y or 16y. Asthma, rhinitis, eczema, and food hypersensitivity (FH) were assessed through questionnaires at 1-2y, 4y, 8y, 12y, and 16y. AP-FGIDs and IBS were assessed through questionnaires at 16y and defined according to the Rome III criteria. Associations between childhood allergy-related diseases and any AP-FGID and IBS and 16y respectively were examined using binomial generalized linear models with a log link function and described as relative risk with 95% confidence intervals. RESULTS: The prevalence of any AP-FGID and IBS at 16y were 12.0% and 6.0% respectively. Eczema at 1-2y, 4y, and 8y, and FH at 12y and 16y were associated with an increased risk for any AP-FGID at 16y. Asthma and FH at 12y and 16y were associated with an increased risk for IBS at 16y. The relative risk for IBS at 16y increased with increasing number of concurrent allergy-related diseases at 16y, but linear trend for relative risk was only borderline statistically significant (P for trend = 0.05). CONCLUSIONS: This prospective population-based study demonstrated positive associations between childhood allergy-related diseases and adolescent AP-FGIDs, including IBS, implicating shared pathophysiology among these disorders.

Serious Infections in Pediatric Inflammatory Bowel Disease 2002-2017-A Nationwide Cohort Study.

OBJECTIVE: To assess absolute and relative risks of serious infections (resulting in inpatient care) in children with inflammatory bowel disease (IBD) compared with the general population. STUDY DESIGN: We identified children (<18 years of age) with a first diagnosis of IBD in the Swedish nationwide health registry (2002-2017; n = 5767) and individuals from the general population matched for sex, age, calendar year, and place of residence (reference group; n = 58 418). Hazard ratios (HRs) for serious infections were estimated using Cox regression separately in children with ulcerative colitis (n = 2287), Crohn's disease (n = 2365), and IBD unclassified (n = 1115). RESULTS: During 17 408 person-years of follow-up, 672 serious infections (38.6/1000 person-years) occurred among the children with IBD compared with 778 serious infections in the reference group (4.0/1000 person-years; adjusted HR (95% CI), 9.46 [8.53-10.5]). HRs were increased for children with ulcerative colitis 8.48 (7.21-9.98), Crohn's disease 9.30 (7.86-11.0), and IBD unclassified 12.1 (9.66-16.1). HRs were highest in the first year of follow-up (HR = 12.6 [10.7-14.9]), then decreasing to a 4.8-fold increased risk beyond 10 years of follow-up. Particularly high HRs were also seen in children with IBD undergoing surgery. Apart from a high relative risk of gastrointestinal infections resulting in hospitalization, children with IBD were also at an increased risk of opportunistic infections (HR = 11.8 [6.17-22.5]). CONCLUSIONS: Children with IBD have an increased risk of serious infection requiring hospitalization compared with the general population.

No Evidence for Increased Brain Tumour Incidence in the Swedish National Cancer Register Between Years 1980-2012.

BACKGROUND/AIM: The main objective of this study was to evaluate if there was an increased incidence of brain tumours between years 1980-2012, a time period when mobile phone usage has increased substantially. MATERIALS AND METHODS: From the Swedish Cancer Registry, cases of meningiomas, low-grade gliomas (LGG) and high-grade gliomas (HGG) were identified in patients between 1980-2012. Direct age-standardised incidence rates were used to calculate incidence trends over time. RESULTS: A total of 13,441 cases of meningiomas, 12,259 cases of high-grade gliomas and 4,555 cases of LGG were reported to the register during the study period. The results suggest that there may be a negative development in the trend for LGG of -0,016 cases per 100,000 and year, corresponding to a mean reduction of approximately 1% per year. CONCLUSION: The present study was not able to demonstrate an increased incidence of glioma during the past 30 years in Sweden.

[Survival increases for all cancer diagnoses - but inequality persists]. / Överlevnaden ökar vid all cancer ­ men ojämlikheten kvarstår - Konceptet ¼rätt resurser med rätt åtgärd till rätt patient vid rätt tillfälle« måste få genomslag.

New data show a continuously increased five-year survival for almost all analyzed cancer diagnoses since 1990. It has to be emphasized that the figures are uncertain due to the limited number of patients. The variation is huge and the greatest improvements are seen not least among the three major tumor diseases (breast, colorectal and prostate cancer), where the society, industry and research bodies made the biggest investments over the years. The causes of improved survival can be sought in several areas, such as earlier detection and better treatments. In addition to survival estimates, it is also always of importance to consider aspects around patient related outcome, such as quality of life.

The role of income in brain tumor patients: a descriptive register-based study : No correlation between patients' income and development of brain cancer.

Socioeconomic status (SES) and its association with cancer in general have been thoroughly studied in the last decades. Several studies have shown associations between SES and many types of cancer such as lung cancer, breast cancer, and prostate cancer. For gliomas, no clear occupational or exposure risk factors have been identified, although some possible risk factors such as use of cellular telephone are still controversial. The aim in the present study is to analyze whether there is an association between SES and development of brain cancer. Data from 1999 through 2013 were collected from the Swedish Cancer Registry and from the National Statistics of Sweden. Age-standardized incidence rates for people with different income were calculated using linear regression model. A total of 11,892 patients were included, of which 5675 were meningiomas, 1216 low-grade gliomas, and 5001 high-grade gliomas. No clear trend between increasing incidence rates and higher income was seen in neither of the investigated brain tumor histologies. In conclusion, the results should be interpreted with caution, but there does not seem to be a correlation in this material between increased income and development of brain cancer.
