Background: To assess the incidence rate and prevalence ratio of multiple sclerosis (MS) in Austria. Methods: Hospital discharge diagnosis and MS-specific immunomodulatory treatment prescriptions from public health insurances, covering 98% of Austrian citizens with health insurance were used to extrapolate incidence and prevalence numbers based on the capture-recapture method. Results: A total of 1,392,629 medication prescriptions and 40,956 hospitalizations were extracted from 2 data sources, leading to a total of 13,205 patients. The incidence rate and prevalence ratio of MS in Austria based on the capture-recapture method were 19.5/100,000 person-years (95% CI 14.3-24.7) and 158.9/100,000 (95% CI 141.2-175.9), respectively. Female to male ratio was 1.6 for incidence and 2.2 for prevalence. Conclusions: Incidence rates and prevalence ratios of MS in our study are within the upper range of comparable studies across many European countries as well as the United States.

Context: Recently, the incidence and prevalence of multiple sclerosis (MS) have increased drastically in different regions of the world, including Asia. The present study aimed to systematically review the recent MS epidemiology in Asia, New Zealand, and Australia. Methods: A systematic literature search was performed in Medline and Embase databases to retrieve the available studies regarding MS epidemiology in Asia, New Zealand, and Australia. Results: Most of the studies were performed in hospital settings. The female-to-male ratio in the sample populations varied from 1.5:1 in Turkey to 5:1 in Malaysia. The total mean age at the onset of MS varied from the minimum of 28 years in Hong Kong to the maximum of 36 years in the United Arab Emirates. Among 16 pertinent studies in this regard, seven addressed the incidence rate of MS, and 13 addressed the prevalence of the disease. The highest prevalence rate was reported to be respectively 124.2 and 148.06 in Australia and Iran versus 2.73 in Malaysia (06 per 100,000 population), while a higher incidence rate was estimated at 6.88 and 6.7 per 100,000 population in Kuwait and Australia, respectively compared to the lower incidence rate per 100,000 population in China (0.2 in females, 0.12 in males). Conclusions: According to the results, the prevalence of MS has increased in Asia, while the prevalence of MS in this continent is lower compared to the rates reported in Australia, Europe, and North America.

Abstract Background The United States has large regional variation in primary prevention campaigns for skin cancer. We collected data from all 50 states to examine changes in melanoma incidence and performed age-period-cohort analyses to describe the simultaneous effects of age, period, and cohort on incidence rates. Methods Annual melanoma incidence rates for non-Hispanic whites from 2001 to 2015 were extracted from the US Cancer Statistics registry. Secular trends were examined overall and by sex and state. We used joinpoint regression to compute annual percent change and average annual percent change and corresponding 95% confidence intervals (CIs). We also analyzed incidence trends by 5-year age group and birth cohort using incidence rate ratios and age-period-cohort modeling. Results Melanoma incidence increased from 20.7 per 100 000 (95% CI = 20.5 to 20.9) in 2001 to 28.2 per 100 000 (95% CI = 28.0 to 28.5) in 2015, increasing by 3.90% (95% CI = 2.36% to 5.48%) annually between 2001 and 2005 and 1.68% (95% CI = 1.37% to 1.99%) annually from 2005 through 2015. The average annual percent change in melanoma incidence rates were similar for men (2.34%, 95% CI = 1.91 to 2.78) and women (2.25%, 95% CI = 1.60 to 2.91). Age-specific relative risk by birth cohort increased from circa 1921 to 1981 before decreasing. Compared with adults born circa 1956, those born circa 1991 had lower melanoma risk (incidence rate ratio  = 0.85; 95% CI = 0.77 to 0.94). Geographic variation was observed; some states still have melanoma rates trending upwards in all birth cohorts. Conclusions The continued increase in melanoma incidence among non-Hispanic whites, particularly in states where rates continue to rise among recent and current birth cohorts, underscores the need for increased public health campaigns aimed at reducing sun exposure.

Abstract Trimodal or bimodal age-specific incidence rates for Burkitt lymphoma (BL) were observed in the United States general population, but the role of immunosuppression could not be excluded. Incidence rates, rate ratios, and 95% confidence intervals for BL and other non-Hodgkin lymphoma (NHL), by age and CD4 lymphocyte count categories, were estimated using Poisson regression models using data from the United States HIV/AIDS Cancer Match study (1980-2005). BL incidence was 22 cases per 100 000 person-years and 586 for non-BL NHL. Adjusted BL incidence rate ratio among males was 1.6× that among females and among non-Hispanic blacks, 0.4× that among non-Hispanic whites, but unrelated to HIV-transmission category. Non-BL NHL incidence increased from childhood to adulthood; in contrast, 2 age-specific incidence peaks during the pediatric and adult/geriatric years were observed for BL. Non-BL NHL incidence rose steadily with decreasing CD4 lymphocyte counts; in contrast, BL incidence was lowest among people with ≤ 50 CD4 lymphocytes/μL versus those with ≥ 250 CD4 lymphocytes/μL (incidence rate ratio 0.3 [95% confidence interval = 0.2-0.6]). The bimodal peaks for BL, in contrast to non-BL NHL, suggest effects of noncumulative risk factors at different ages. Underascertainment or biological reasons may account for BL deficit at low CD4 lymphocyte counts.

BackgroundCannabis use and cannabis regulatory policies recently re-surfaced as noteworthy global research and social media topics, including claims that Mexicans have been sending cannabis and other drug supplies through a porous border into the United States. These circumstances prompted us to conduct an epidemiological test of whether the states bordering Mexico had exceptionally large cannabis incidence rates for 2002–2011. The resulting range of cannabis incidence rates disclosed here can serve as 2002–2011 benchmark values against which estimates from later years can be compared.MethodsThe population under study is 12-to-24-year-old non-institutionalized civilian community residents of the US, sampled and assessed with confidential audio computer-assisted self-interviews (ACASI) during National Surveys on Drug Use and Health, 2002–2011 (aggregaten ∼ 420,000) for which public use datasets were available. We estimated state-specific cannabis incidence rates based on independent replication sample surveys across these years, and derived meta-analysis estimates for 10 pre-specified regions, including the Mexico border region.ResultsFrom meta-analysis, the estimated annual incidence rate for cannabis use in the Mexico Border Region is 5% (95% CI [4%–7%]), which is not an exceptional value relative to the overall US estimate of 6% (95% CI [5%–6%]). Geographically quite distant from Mexico and from states of the western US with liberalized cannabis policies, the North Atlantic Region population has the numerically largest incidence estimate at 7% (95% CI [6%–8%]), while the Gulf of Mexico Border Region population has the lowest incidence rate at 5% (95% CI [4%–6%]). Within the set of state-specific estimates, Vermont’s and Utah’s populations have the largest and smallest incidence rates, respectively (VT: 9%; 95% CI [8%–10%]; UT: 3%; 95% CI [3%–4%]).DiscussionBased on this study’s estimates, among 12-to-24-year-old US community residents, an estimated 6% start to use cannabis each year (roughly one in 16). Relatively minor variation in region-wise and state-level estimates is seen, although Vermont and Utah might be exceptional. As of 2011, proximity to Mexico, to Canada, and to the western states with liberalized policies apparently has induced little variation in cannabis incidence rates. Our primary intent was to create a set of benchmark estimates for state-specific and region-specific population incidence rates for cannabis use, using meta-analysis based on independent US survey replications. Public health officials and policy analysts now can use these benchmark estimates from 2002–2011 for planning, and in comparisons with newer estimates.

The Impact

Real world evidence studies of mass vaccination across health systems have reaffirmed the safety1 and efficacy2,3 of the FDA-authorized mRNA vaccines for COVID-19. However, the impact of vaccination on community transmission remains to be characterized. Here, we compare the cumulative county-level vaccination rates with the corresponding COVID-19 incidence rates among 87 million individuals from 580 counties in the United States, including 12 million individuals who have received at least one vaccine dose. We find that cumulative county-level vaccination rate through March 1, 2021 is significantly associated with a concomitant decline in COVID-19 incidence (Spearman correlation ρ = −0.22, p-value = 8.3e-8), with stronger negative correlations in the Midwestern counties (ρ = −0.37, p-value = 1.3e-7) and Southern counties (ρ = −0.33, p-value = 4.5e-5) studied. Additionally, all examined US regions demonstrate significant negative correlations between cumulative COVID-19 incidence rate prior to the vaccine rollout and the decline in the COVID-19 incidence rate between December 1, 2020 and March 1, 2021, with the US western region being particularly striking (ρ = −0.66, p-value = 5.3e-37). However, the cumulative vaccination rate and cumulative incidence rate are noted to be statistically independent variables, emphasizing the need to continue the ongoing vaccination roll out at scale. Given confounders such as different coronavirus restrictions and mask mandates, varying population densities, and distinct levels of diagnostic testing and vaccine availabilities across US counties, we are advancing a public health resource to amplify transparency in vaccine efficacy monitoring (https://public.nferx.com/covid-monitor-lab/vaccinationcheck). Application of this resource highlights outliers like Dimmit county (Texas), where infection rates have increased significantly despite higher vaccination rates, ostensibly owing to amplified travel as a “vaccination hub”; as well as Henry county (Ohio) which encountered shipping delays leading to postponement of the vaccine clinics. This study underscores the importance of tying the ongoing vaccine rollout to a real-time monitor of spatio-temporal vaccine efficacy to help turn the tide of the COVID-19 pandemic.

Abstract Background: Multiple Sclerosis (MS) remains to be a public health challenge, due to its unknown biological mechanisms and clinical impacts on young people. The prevalence of this disease in Iran is reported to be 5.30 to 74.28 per 100,000-person. Because of high prevalence of this disease in Fars province, the purpose of this study was to assess the spatial pattern of MS incidence rate by modeling both the effects of spatial dependence between neighboring regions and risk factors in a Bayesian Poisson model, which can lead to the improvement of health resource allocation decisions.Method: Data from 5,468 patients diagnosed with MS were collected, according to the McDonald’s criteria. New cases of MS were reported by the MS Society of Fars province from 1991 until 2016. The association between the percentage of people with low vitamin D intake, smoking, abnormal BMI and alcohol consumption in addition to spatial structure in a Bayesian spatio-temporal hierarchical model were used to determine the relative risk and trend of MS incidence rate in 29 counties of Fars province. Results: County-level crude incidence rates ranged from 0.22 to 11.31 cases per 100,000-person population. The highest relative risk was estimated at 1.80 in the county of Shiraz, the capital of Fars province, while the lowest relative risk was estimated at 0.11 in Zarindasht county in southern of Fars. The percentages of vitamin D supplementation intake and smoking were significantly associated with the incidence rate of MS. The results showed that 1% increase in vitamin D supplementation intake is associated with 2% decrease in the risk of MS and 1% increase in smoking is associated with 16% increase in the risk of MS.Conclusion: Bayesian spatio-temporal analysis of MS incidence rate revealed that trend is less steep than the mean trend of this disease in the south and south east of Fars province, which is due to the association between the higher percentage of vitamin D supplementation intake and the lower percentage of smoking. Previous studies have also shown that smoking and low vitamin D, among all covariates or risk factors, might be associated with high incidence of MS.

Multiple Sclerosis Epidemiology

In the Russian Federation, multiple sclerosis prevalence rates vary from 10 to 80 cases per 100,000, depending on region and the nationality of the population. The main characteristics of multiple sclerosis epidemiology in the XX century in this big territory are: (1) steady increase in multiple sclerosis prevalence and incidence rates, maybe because of better diagnosis and treatment, but also changes in environmental/epigenetic risk profile and/or lifestyle factors; (2) increase of the female to male ratio, increase in multiple sclerosis incidence mainly in females; (3) appearance and increasing frequency of multiple sclerosis in ethnic groups, previously free of multiple sclerosis (Northern Tribes, Yakuts and others). The latest data show that in European Russia, the multiple sclerosis prevalence varies from 30 to 80 cases, in Siberia—from 20 to 70 cases, with steady increases, especially in women.

e17005 Background: Information on trend of Chronic Myeloid Leukemia (CML) incidence rate is scant. This study was conducted to evaluate the time trends of CML incidence rates among Caucasians in the U.S. Methods: We used the Surveillance, Epidemiology, and End Results (SEER) Program to extract annual age-adjusted incidence rates of CML from 1973-2008 for <60yr and >60yr age groups classified by gender. Trends of incidence rates were evaluated using the National Cancer Institute’s Joinpoint Regression Program (v 3.5.2). The maximum number of joinpoints used was 4. The annual percentage change (APC %) for the final selected joinpoint model for each cohort is shown in the table. Results: The annual age-adjusted CML incidence rates for 1973 vs. 2008 were 0.72/0.67, 5.67/4.47, 0.93/0.67, and 10.5/8.5 per 100,000 population for the 4 cohorts: women (<60yr, >60yr) and men (<60yr, >60yr), respectively. Among Caucasian women (>60yr), the incidence rate decreased significantly from 5.58/100,000 in 2001 to 4.47/100,000 in 2008 (APC= -3.08, CI -5.8 to -0.3, p = 0.004). The incidence trend from 1973-2001 was stable for this cohort (APC=0.1, CI -0.3 to 0.5). The incidence trends among women <60yr, men <60yr, and men >60yr were stable from 1973-2008. Conclusions: The annual age-adjusted incidence rates of chronic myeloid leukemia among older (>60 year) Caucasian women has declined sharply from 2001-2008. The rate change is unexplained. It may help generate hypotheses regarding risk factors for CML. [Table: see text]

Background: Patients with multiple sclerosis (MS) are potentially at high risk of fracture due to falls and osteoporosis. Objective: To estimate incidence rates of fractures in MS patients, stratified by fracture type, sex and age, and to compare these rates with controls. Methods: The case population consisted of all patients with an accepted diagnosis of MS in the Danish MS Registry (1949–2007). Data were linked to the National Hospital Discharge Register (1977–2007). Patients with MS ( n = 11,157) were 1:6 matched by year of birth, gender, calendar time and region to persons without MS (controls). Incidence rates of fracture were estimated as the number of fractures per 1000 person-years. Incidence rate ratios (IRRs) were calculated by dividing fracture rates in MS patients by fracture rates in controls. Results: Among patients with MS, the incidence rate of any fracture yielded 22.8 per 1000 person-years. The IRR of any fracture between MS patients and controls was 1.40 (95% CI 1.33–1.46). In particular, IRRs of tibia fracture (3.36 [2.75–4.11]), femur fracture (6.66 [5.06–8.76]) and hip fracture (3.20 [2.83–3.62]) were elevated in MS patients versus controls. Conclusion: Fractures occurred more often in patients with MS, especially fractures of the tibia, hip and femur.
