Sexually Transmissible Infections

Background Given the growing popularity of administrative data for health research, information on the differences and similarities between administrative data and customary data sources (e.g. surveillance) will help to inform the use of administrative data in the field of sexually transmissible infections (STIs). The objective of this study was to compare the incidence rates of three nonviral STIs from a large health insurance administrative database (MarketScan) with surveillance data. Methods: We computed and compared STI rates for 2005–10 from MarketScan and national surveillance data for three major nonviral STIs (i.e. chlamydia (Chlamydia trachomatis), gonorrhoea (Neisseria gonorrhoeae) and syphilis (Treponema pallidum)). For administrative data, we assessed the sensitivity of the rates to enrolee inclusion criteria: continuous (≥320 member-days) versus all enrolees. Relative rates were computed for 5-year age groups and by gender. Results: The administrative database rates were significantly lower (P < 0.01) than those in the national surveillance data, except for syphilis in females. Gonorrhoea and syphilis rates based on administrative data were significantly lower (P < 0.01) for all enrolees versus continuous enrolees only. The relative STI rates by age group from the administrative data were similar to those in the surveillance data. Conclusions: Although absolute STI rates in administrative data were lower than in the surveillance data, relative STI rates from administrative data were consistent with national surveillance data. For gonorrhoea and syphilis, the estimated rates from administrative data were sensitive to the enrolee inclusion criteria. Future studies should examine the potential for administrative data to complement surveillance data.

The Impact

The Kingdom of Saudi Arabia is one of the largest Arab countries with a moderate annual problem of tuberculosis that is either pulmonary or extra-pulmonary. TB is still one of the most significant health troubles in the KSA, affecting different nationalities (Saudis, non-Saudis), ages, provinces, and genders. The control of TB still faces some challenges in different provinces of the KSA. Data were collected, arranged, analyzed and presented in tables and figures. In this retrospective study, we appraised TB surveillance data for the period between 2013 (1434H) and 2018 (1439H). Data were handled using Microsoft Excel and SPSS version 23. Data were checked for normality using Shapiro-Wilk normality test at 0.05 levels to determine whether they are parametric or nonparametric. Chi-squared, Kruskal Wallis, and analysis of variance tests were used to evaluate trends at a significance level of p< 0.05. Statistical analyses were performed using IBM-SPSS version 23 for Mac OS. We appraised TB surveillance data for the period between 2013 (1434H) and 2018 (1439H). The data included the region of the country (province), age, sex, and nationality (Saudis, non-Saudis). The study evaluated the impact of TB on various nationalities (Saudis and non-Saudis), age groups (0-14, 15-34, 35-55, more than 55 years old), and genders (males and females). Non-Saudis had a higher incidence rate than Saudis in 2013-2018. The number of cases and incidence rates of TB recorded in males between 2013 to 2018 were about two to three times greater than estimates for females. The Makkah, Riyadh, and Jeddah regions attract enormous numbers of non-Saudi migrant workers, who account for ~60% of all TB cases in the KSA. Assessing the main TB risk factors contributing to high TB rates in non-Saudi workers is essential. Furthermore, periodical accurate studies, including evidence-based studies for optimum surveillance, avoidance, spread risk, inspection, control procedures and treatment of TB, should be conducted. These assessments would lead to evaluating the strengths and weaknesses of KSA-NTP’s TB action plan.

Future Challenges

Epidemic conjunctivitis can be associated with viral or bacterial pathogens, whereas epidemic keratoconjunctivitis is caused mainly by adenoviruses type 8,19 and 37. In Germany, the incidence of adenovirus conjunctivitis cases increased from 0.2 per 100 000 inhabitants (in 2001 and 2002) eventually to 0.5 in 2003 and 0.8 in 2004. The detection of adenovirus in conjunctival swabs is notifiable to the local health departments. Data about cases with positive conjunctival swabs are then transmitted to the Robert Koch-Institut. Quality control of data takes place and national surveillance data of confirmed cases with adenovirus conjunctivitis are published. From January to April 2004 the national surveillance system captured an outbreak with 1024 cases (131 laboratory confirmed). Analysis of the national surveillance data showed that in March 2004 the group primarily affected by epidemic keratoconjunctivitis was young men between 18 -29 years old followed by an increased number of notifications from women in the same age group. Meanwhile the German Armed Forces experienced an outbreak of conjunctivitis, almost exclusively without laboratory confirmation, affecting 6378 soldiers. Despite the small number of laboratory confirmed cases it became clear from the analysis of the national surveillance data that person-to-person transmission between young men and similar age groups of the population did occur. Whether the outbreak started within the garrisons of the German Armed Forces or whether it was triggered within these accommodations, there is clearly a need for the national and the military public health institutions to work together on guidelines to handle future challenges.

Objective Ubiquitous throughout the literature and during patient counseling, vestibular schwannoma is often quoted to affect about 1 per 100,000 people. Yet, reports from distinct international populations suggest that the incidence is likely much higher. The objective of the current work was to systematically characterize the global incidence of sporadic vestibular schwannoma. Data Sources Scopus, Embase, and PubMed. Review Methods Population-based studies reporting incidence rates of sporadic vestibular schwannoma between January 2010 and August 2020 were searched with language restrictions requiring reports to be published in Chinese, English, German, Italian, or Spanish. The protocol was registered with PROSPERO (CRD42021228208) prior to commencement of data collection. PRISMA guidelines for transparent reporting of systematic reviews were followed. Results Among 424 citations, 6 publications covering 4 distinct populations from Denmark, the Netherlands, Taiwan, and the United States met inclusion criteria. Most recent incidence rates of among all ages ranged between 3.0 and 5.2 per 100,000 person-years. Highest incidence rates were reported among patients aged ≥70 years, peaking at 20.6 per 100,000 person-years. One study from the United States reported the incidence of asymptomatic, incidentally diagnosed tumors at a rate of 1.3 per 100,000 person-years from 2012 to 2016. Conclusions Recent international incidence rates of sporadic vestibular schwannoma exceed the commonly quoted “1 per 100,000” figure by up to 5-fold among all ages and by up to 20-fold among age groups at highest risk. Based on modern incidence rates, the lifetime prevalence of developing sporadic vestibular schwannoma likely exceeds 1 per 500 persons.

Paraneoplastic Neurologic Syndromes

ObjectiveTo determine the observed and expected incidence rates of paraneoplastic neurologic syndromes (PNSs) and autoimmune encephalitides (AEs) diagnosed in France between 2016 and 2018, we conducted a population-based epidemiologic study.MethodsObserved incidence rates were stratified by sex, age groups, region of care, year of diagnosis, and disease subgroups. National expected incidence rates were calculated based on rates obtained in the area directly adjacent to the Reference Center using a mixed Poisson model and compared with observed incidence rates.ResultsSix hundred thirty-two patients with definite PNS or AE met the inclusion criteria. The observed incidence rate of definite PNS and AE in France was 3.2 per million person-years (CI95%: 2.9–3.4) compared with an expected incidence rate of 7.1 per million person-years (CI95%: 3.9–11.4). The national observed incidence rate for the antibody-positive AE subgroup increased from 1.4 per million person-years (CI95%: 1.2–1.7) in 2016 to 2.1 per million person-years (CI95%: 1.7–2.4) in 2018, thus surpassing the incidence rate of classical PNS (1.2 per million person-years [CI95%: 1.0–1.5]) of 2018.ConclusionsThere was a significant widespread year-to-year increase in the incidence of diagnoses registered with the Reference Center for all subgroups of PNS and AE studied. The national observed incidence rate is likely underestimated due to underdiagnosis and underreporting.

This study aimed to investigate the annual incidence of parapharyngeal and retropharyngeal abscess (PRPA) based on 10-year population-based data. Patients with PRPA were identified from the Taiwan Health Insurance Research Database, a database of all medical claims of a randomly selected, population-representative sample of over two million enrollees of the National Health Insurance system that covers over 99% of Taiwan’s citizens. During 2007–2016, 5779 patients received a diagnosis of PRPA. We calculated the population-wide incidence rates of PRPA by sex and age group (20–44, 45–64, and >64) as well as in-hospital mortality. The annual incidence rate of PRPA was 2.64 per 100,000 people. The gender-specific incidence rates per 100,000 people were 3.34 for males and 1.94 for females with a male:female gender ratio of 1.72. A slight increase in incidence rates among both genders over the study period was noted. Age-specific rates were lowest in the 20–44 age group with a mean annual incidence of 2.00 per 100,000 people, and the highest rates were noted in the age groups of 45–64 and >64 years with mean annual incidences of 3.21 and 3.20, respectively. We found that PRPA is common in Taiwan, males and older individuals are more susceptible to it, and incidence has increased in recent years.

Last August, when the delta variant became the dominant infection strain, Israel, one of the countries with the highest levels of vaccination in the world, faced a scary pandemic wave. The frighteningly increasing number of infections was seen as the perfect storm to test the effectiveness of the mRNA BNT162b2 vaccine. The new surge forced the government to use a booster shot to protect the most vulnerable age groups. Starting from the August national surveillance data, we analysed the temporal effectiveness of vaccination against severe infections in the Israeli over 60 population. The study shows that the two-dose vaccine still works in preventing people from getting seriously sick but not with the same effectiveness observed in the first months of 2021. However, the observed temporal increase of the vaccine effectiveness in Israel, during August, suggests a correlation with the increase of the population protected by the booster shot.

Objective Despite the significant morbidity and mortality associated with pheochromocytoma and paraganglioma, little is known about their epidemiology. The primary objective was to determine the incidence of pheochromocytoma and paraganglioma in an ethnically diverse population. A secondary objective was to develop and validate algorithms for case detection using laboratory and administrative data. Design Population-based cohort study in Alberta, Canada from 2012 to 2019. Methods Patients with pheochromocytoma or paraganglioma were identified using linked administrative databases and clinical records. Annual incidence rates per 100 000 people were calculated and stratified according to age and sex. Algorithms to identify pheochromocytoma and paraganglioma, based on laboratory and administrative data, were evaluated. Results A total of 239 patients with pheochromocytoma or paraganglioma (collectively with 251 tumors) were identified from a population of 5 196 368 people over a period of 7 years. The overall incidence of pheochromocytoma or paraganglioma was 0.66 cases per 100 000 people per year. The frequency of pheochromocytoma and paraganglioma increased with age and was highest in individuals aged 60–79 years (8.85 and 14.68 cases per 100 000 people per year for males and females, respectively). An algorithm based on laboratory data (metanephrine >two-fold or normetanephrine >three-fold higher than the upper limit of normal) closely approximated the true frequency of pheochromocytoma and paraganglioma with an estimated incidence of 0.54 cases per 100 000 people per year. Conslusion The incidence of pheochromocytoma and paraganglioma in an unselected population of western Canada was unexpectedly higher than rates reported from other areas of the world.

Health Insurance Reform

Since 2009, the National Health Insurance in Korea (NHI) has been implementing a series of policies to expand the scope of dental benefits. This study reviewed the changes in co-payments and dental use patterns before (2008 to 2012) and after (2013 to 2017) the NHI’s dental health insurance reform. The study used Korea Health Panel data of 7681 households (16,493 household members) from a 10-year period (2008–2017). Dental expenditures and equivalent income using square root of household size were analyzed. Dental services were categorized into 13 types and a concentration index and 95% confidence interval using the delta method was calculated to identify income-related inequalities by a dental service. Dental expenditures and the number of dental services used increased significantly, while the proportion of out-of-pocket spending by the elderly decreased. The expenditure ratio for implant services to total dental expenditures increased substantially in all age groups, but the ratio of expenditures for dentures and fixed bridges decreased relatively. The concentration index of implant services was basically in favor of the rich, but there was no longer a significant bias favoring the better-off after the reforms. The dental health insurance reform in Korea appears to contribute not only to lowering the ratio of out-of-pocket to total dental expenses per episode in the elderly but also to improving the inequality of dental expenses.
