Disease trends after Helicobacter pylori eradication based on Japanese nationwide claims and the health check-up database

BACKGROUND Helicobacter pylori(H.pylori)infection is a risk factor for many diseases,including peptic ulcer disease and gastric cancer.While H.pylori eradication therapy can prevent these diseases,potentially unfavorable effects of eradication therapy have also been reported in some diseases,such as gastroesophageal reflux disease(GERD),Barrett’s esophagus(BE),inflammatory bowel disease(IBD),allergic diseases,and metabolic diseases.Consequently,both positive and negative impacts should be considered when assessing the effects of H.pylori eradication therapy.AIM To compare the incidence of these diseases before and after H.pylori eradication and to comprehensively assess its effects.METHODS This retrospective cohort study used a Japanese nationwide health claims database(April 2009-March 2020),developed by the Japanese Ministry of Health,Labour and Welfare.The database contained almost all health insurance claims data issued in Japan,and specific health check-up data for individuals who took the check-ups.Descriptive statistics were used for the analyses.Patients who received primary eradication therapy were defined as those prescribed medication for H.pylori eradication.New diagnoses,defined as incidence of upper gastrointestinal diseases and IBD,and prevalence of allergic diseases were compared before and after eradication.The incidence and prevalence of each disease were also compared between the 3-year period before eradication(from the 4th to the 2nd year prior to the year of eradication)and the 3-year period after eradication(from the 1st to the 3rd year after the year of eradication)based on the age category and calendar year and month.Changes in body mass index and proportion of patients with metabolic syndrome(MS)were examined before and after eradication.RESULTS We identified 5219731 patients who received primary eradication therapy.The 65-69 years age group had the greatest number of patients in both sexes.There was no significant increase in the incidence of GERD after eradication when considering the effects of aging and reporting period.However,the incidence of BE was higher in the 3-year period after eradication than in the 3-year period before eradication for all age categories(0.02%-0.10%vs<0.01%-0.05%).The incidence of IBD and prevalence of allergic disease were also higher after eradication.In contrast,the incidence of gastric and duodenal ulcers and gastritis was reduced after eradication.In patients with at least one entry of health check-up data(1701111 patients),the percentage of patients with MS showed a slight increase following eradication(11.0%in the year of eradication and 12.2%after 5 years).CONCLUSION The results suggest that H.pylori eradication therapy reduces peptic ulcers and gastritis;however,it is associated with increased incidence of several other chronic diseases.

Herbs and management of hypertension:Claims,criticism,and challenges

Hypertension(HTN)is one of the most common chronic diseases affecting over 30%of the adult population globally,with a growing incidence rate.This article aims to identify the commonly used herbs for HTN treatment and examine their claims,criticisms,and challenges.It further aims to provide useful recommendations regarding the use of herbs for HTN treatment.HTN complications,such as coronary heart disease,stroke,peripheral vascular disease,vision impairment,and renal failure can result in morbidity and mortality.The high cost of conventional medications,which sometimes may not even be available or easily accessible with their unfavorable side effects as well as taking more than one pill per day,has led hypertensive patients,particularly those in rural areas,to explore alternative treatments such as herbal therapies.It is crucial to determine the different modes of action,doses,safety,and efficacy of herbal remedies used in combination with conventional medications to improve treatment adherence and enhance patient outcomes.

EXPECTED PRESENT VALUE OF TOTAL DIVIDENDS IN THE COMPOUND BINOMIAL MODEL WITH DELAYED CLAIMS AND RANDOM INCOME

In this paper, a compound binomial model with a constant dividend barrier and random income is considered. Two types of individual claims, main claims and by-claims, are defined, where every by-claim is induced by the main claim and may be delayed for one time period with a certain probability. The premium income is assumed to another binomial process to capture the uncertainty of the customer＇s arrivals and payments. A system of difference equations with certain boundary conditions for the expected present value of total dividend payments prior to ruin is derived and solved. Explicit results are obtained when the claim sizes are Kn distributed or the claim size distributions have finite support. Numerical results are also provided to illustrate the impact of the delay of by-claims on the expected present value of dividends.

电子病历系统与医务结算系统间的数据交换规格CLAIM(CLinical Accounting InforMation)汉化版的制作

CLinical Accounting InforMation(CLAIM)是日本开发的电子病历系统与医务结算系统间的数据交换规格。它使用eXtensible Markup Language(XML)作为标记语言,是不同医疗设施之间医疗数据交换规格Medical Markup Language(MML)的从属规格。CLAIM继承了MML2.x的基本结构,目前的版本2.1包括受理、预约、诊疗行为、结算金额等信息的两个模块和9个数据定义表格。考虑到中国现在还没有一个使用XML结构电子病历系统与医务结算系统之间信息的规格,鉴于CLAIM的柔韧性,我们制作了它的汉化版。由于日本的医务结算系统中采用"点数"制度,而中国的医院中没有此概念,另外,处方的书写形式等也与日本不同,所以我们重新制作了这两个模块,并相应的追加和修改了一些表格。CLAIM汉化版的制作将使中国医院的电子病历系统与医务结算系统之间有效而方便地进行数据交换成为可能。

Applications of Mogulskii, and Kurtz-Feng Large Deviation Results to Risk Reserve Processes with Aggregate Claims

In this paper we examine the large deviations principle (LDP) for sequences of classic Cramér-Lundberg risk processes under suitable time and scale modifications, and also for a wide class of claim distributions including (the non-super- exponential) exponential claims. We prove two large deviations principles: first, we obtain the LDP for risk processes on D∈[0,1] with the Skorohod topology. In this case, we provide an explicit form for the rate function, in which the safety loading condition appears naturally. The second theorem allows us to obtain the LDP for Aggregate Claims processes on D∈[0,∞) with a different time-scale modification. As an application of the first result we estimate the ruin probability, and for the second result we work explicit calculations for the case of exponential claims.

Double Misplaces of SOE＇s Ownership and the Loss of Claim Rights

Modem enterprise theory defines onterprise＇s ownership through the concepts of residual rights of control and claim to residue. It also believes that when they are in homologous, the ownership of enterprise can be arranged in the best place. When the enterprise is under normal run, shareholders are its owner, but when it goes into bankruptcy, claimers should take place of shareholders becoming the owner of the enterprise. But in China, the ownership of state-owned enterprise （SEE） goes into double misplaces. Management controls the enterprise under the normal run, which leads salaries to seize the earnings and share equities. The state who acts as the shareholder not only lessens investments but also fixes its earnings as much as possible. It gives up the claim to residue, which leads claimers to bear the enterprise＇s residual risks （when the residual income is negative）. When the enterprise goes into bankruptcy, as the shareholder, the state determines whether it can exist or not in order to maximize its own utility. Rights of claimer are being seriously damaged as they can be manipulated freely in the enterprise. Banks＇ bad debts are also in an extremely high level. In this article, the author will establish a model and use the relative data to do technical analysis.

Claims in International Construction Contract: A Case Study

Claims in international civil engineering projects sometimes will have impact on implementing the contract successfully. in order to observe and evaluate the contract claim situation and give guideline to all the contractual roles to settle the claims comfortably, this paper devote the research and literate review to find the key problems in contract claim management and give recommendation accordingly. With this focused objective, this paper presents a research analysis based on randomly selected data from international construction organization. The contract claim case studies analyzed by sampling survey scientific research method that follows a research strategy of specific to general. In the beginning, the paper analyzes the elements of contract claim administration,and then provides the general overview of the contract claim. Finally, it numerates the claim causes usage through cases studies under different contract condition of FIDIC. In addition to these discussions, analysis of other secondary data and recommendations forwarded to explain how claims should handle properly. During the thesis research period,there were 14 simple random selected projects have been studied as a case studies. From studied projects,the time extension in average, exceed 117.7% of its original contract completion time and the cost compensation increase 34.8% comparing to its initial contract value. Thus, the main causes of the majority contract claim problem lies on the failure in contract claim management and on unforeseen circumstance like variation, adverse climate, right of way problems, etc. Finally this thesis contributes to the improvement of contract claim management construction industry and open ways for further researches related to claim management.

ON THE RUIN FUNCTIONS FOR A CORRELATED AGGREGATE CLAIMS MODEL WITH POISSON AND ERLANG RISK PROCESSES

This article considers a risk model as in Yuen et al. （2002）. Under this model the two claim number processes are correlated. Claim occurrence of both classes relate to Poisson and Erlang processes. The formulae is derived for the distribution of the surplus immediately before ruin, for the distribution of the surplus immediately after ruin and the joint distribution of the surplus immediately before and after ruin. The asymptotic property of these ruin functions is also investigated.

Identification of cancer patients using claims data from health insurance systems: A real-world comparative study

Objective: To evaluate the accuracy of identifying cancer patients by use of medical claims data in a health insurance system in China, and provide the basis for establishing the claims-based cancer surveillance system in China.Methods: We chose Hua County, Henan Province as the study site, and randomly selected 300 and 1,200 qualified inpatient electronic medical records(EMRs) as well as the New Rural Cooperative Medical Scheme(NCMS) claims records for cancer patients in Hua County People’s Hospital(HCPH) and Anyang Cancer Hospital(ACH) in 2017. Diagnostic information for NCMS claims was evaluated on an individual level, and sensitivity and positive predictive value(PPV) were calculated taking the EMRs as the gold standard.Results: The sensitivity of NCMS was 95.2%(93.8%-96.3%) and 92.0%(88.3%-94.8%) in ACH and HCPH,respectively. The PPV of the NCMS was 97.8%(96.7%-98.5%) in ACH and 89.0%(84.9%-92.3%) in HCPH.Overall, the weighted and combined sensitivity and PPV of NCMS in Hua County was 93.1% and 92.1%,respectively. Significantly higher sensitivity and PPV in identifying patients with common cancers than noncommon cancers were detected in HCPH and ACH separately(P<0.01).Conclusions: Identification of cancer patients by use of the NCMS is accurate on individual level, and it is therefore feasible to conduct claims-based cancer surveillance in areas not covered by cancer registries in China.

Real-world treatment patterns of gastrointestinal neuroendocrine tumors: A claims database analysis

AIM To describe real-world treatment patterns of gastrointestinal neuroendocrine tumors(GI NET).METHODS In this retrospective cohort study,we used 2009-2014 data from 2 United States commercial claims databases to examine newly pharmacologically treated patients using tabular and graphical techniques. Treatments included somatostatin analogues(SSA),cytotoxic chemotherapy(CC),targeted therapy(TT),interferon(IF) and combinations. We identified patients at least 18 years of age,with ≥ 1 inpatient or ≥ 2 outpatient claims for GI NET who initiated pharmacologic treatment from 7/1/09-6/30/14. A 6 mo clean period prior to first treatment ensured patients were newly treated. Patients were followed until end of enrollment or the study end date,whichever was first.RESULTS We identified 2258 newly treated GI NET patients: mean(SD) age was 55.6 years(SD = 9.7),47.2% of the patients were between 55 and 64 years,and 48.8% were female. All regions of the United States were represented. 59.6% started first-line therapy with SSA monotherapy(964 with octreotide LAR,380 with octreotide SA,and 1 with lanreotide),33.3% CC,3.6% TT,and 0.5% IF. The remainder received combinations. Mean follow up was 576 d. Overall mean first-line therapy duration was 361 d(449 d for SSA,215 for CC,267 for TT). 58.9% of patients had no pharmacological treatment beyond first line. The most common secondline was combination therapy with SSA. In graphical pattern analysis,there was no clear pattern visible after first line therapy.CONCLUSION In this study,60% of patients initiated treatment with SSA alone or in combination. The relatively long time to discontinuation suggests possible sustained effectiveness and tolerability.

Climate Change and Heavy Rainfall-Related Water Damage Insurance Claims and Losses in Ontario, Canada

The objective of this paper was to project possible impacts of climate change on heavy rainfall-related water damage insurance claims and incurred losses for four selected cites (Kitchener-Waterloo, London, Ottawa, and Toronto) located at Ontario, Canada. To achieve this goal, the future climate change scenarios and rainfall simulations, at local scale, were needed. A statistical downscaling method was used to downscale five global climate model (GCM) scenarios to selected weather stations. The downscaled meteorological variables included surface and upper-air hourly temperature, dew point, west-east and south-north winds, air pressure, and total cloud cover. These variables are necessary to project future daily rainfall quantities using within-weather-type rainfall simulation models. A model result verification process has been built into the whole exercise, including rainfall simulation modeling and the development of downscaling transfer functions. The results of the verification, based on historical observations of the outcome variables simulated by the models, showed a very good agreement. To effectively evaluate heavy rainfall-related water damage insurance claims and incurred losses, a rainfall index was developed considering rainfall intensity and duration. The index was evaluated to link with insurance data as to determination of a critical threshold of the rainfall index for triggering high numbers of rainfall-related water damage insurance claims and incurred losses. The relationship between rainfall index and insurance data was used with future rainfall simulations to project changes in future heavy rainfall-related sewer flood risks in terms of water damage insurance claims and incurred losses. The modeled results showed that, averaged over the five GCM scenarios and across the study area, both the monthly total number of rainfall-related water damage claims and incurred losses could increase by about 13%, 20% and 30% for the periods 2016-2035, 2046-2065, and 2081-2100, respectively (from the four-city seasonal average of 12 ± 1.7 thousand claims and $88 ± $21 million during April-September 1992-2002). Within the context of this study, increases in the future number of insurance claims and incurred losses in the study area are driven by only increases in future heavy rainfall events.

Shorebirds, Stakeholders, and Competing Claims to the Beach and Intertidal Habitat in Delaware Bay, New Jersey, USA

Birds have specific habitat needs as a function of their life cycle and reproductive stage. Migrant shorebirds that may fly from the Arctic to the southern tip of South America have foraging and habitat requirements at sites where they stop to refuel before continuing their migration north or south. Throughout the world, shorebirds mainly forage on mudflats at low tide. Red knots (Calidris canutus rufa) are threatened in the United States and elsewhere, and it is critical to determine factors that might contribute to their decline. This paper uses Delaware Bay as a case study to examine shorebird (and red knot) use of the intertidal habitat, and competing claims to habitats they require during their northward migration, as well as some of the key stakeholders that play a role in protecting red knots. Shorebirds are drawn to Delaware Bay to feed on the eggs of Horseshoe Crabs (Limulus polyphemus) that are concentrated at the high tide. But they also feed on the intertidal mudflat. We examined intertidal habitat use on 17 beaches in an extensive study in 2015, and 5 key beaches in 2016. Most of the beaches were longitudinal, but four were more complex, and were used extensively for resting as well as foraging;numbers there were higher than on the longitudinal beaches. On foraging beaches, some shorebirds were present on over 85% of the intertidal censuses, and red knots were present on over 48% of the intertidal censuses. Average numbers of red knots on the longitudinal beaches varied from 0 to 354 ± 116 when any shorebirds were present, but averaged up to 1184 ± 634 when knots were present in 2015. Some beaches in 2015 had no knots (a beach with long-term aquaculture). Tide, intertidal location, and beach (name) determined the number of knots (and all shorebirds). Numbers decreased with distance from the mean high tide line. The average number of knots present in the intertidal mudflats two hours before or after low tide when knots were present (e.g. no censuses with zeros) was 2040 (=maximum flock size, in 2015). Major threats to red knots are from recreationists, overfishing of horseshoe crabs (reduction in egg prey base), and use of the intertidal by aquaculture. We discuss the role of stakeholders in conservation and protection of red knots.

A Statistical Analysis of Intensities Estimation on the Modeling of Non-Life Insurance Claim Counting Process

This study presents an estimation approach to non-life insurance claim counts relating to a specified time. The objective of this study is to estimate the parameters in non-life insurance claim counting process, including the homogeneous Poisson process (HPP) and the non-homogeneous Poisson process (NHPP) with a bell-shaped intensity. We use the estimating function, the zero mean martingale (ZMM) as a procedure of parameter estimation in the insurance claim counting process. Then, Λ(t) , the compensator of is proposed for the number of claims in the time interval . We present situations through a simulation study of both processes on the time interval . Some examples of the situations in the simulation study are depicted by a sample path relating to its compensator Λ(t). In addition, an example of the claim counting process illustrates the result of the compensator estimate misspecification.

Estimates for the ruin probability of a time-dependent renewal risk model with dependent by-claims

Consider a continuous-time renewal risk model, in which every main claim induces a delayed by-claim. Assume that the main claim sizes and the inter-arrival times form a sequence of identically distributed random pairs, with each pair obeying a dependence structure, and so do the by-claim sizes and the delay times. Supposing that the main claim sizes with by-claim sizes form a sequence of dependent random variables with dominatedly varying tails, asymptotic estimates for the ruin probability of the surplus process are investigated, by establishing a weakly asymptotic formula, as the initial surplus tends to infinity.

Asymptotics of discounted aggregate claims for renewal risk model with risky investment

Under the assumption that the claim size is subexponentially distributed and the insurance surplus is totally invested in risky asset, a simple asymptotic relation of tail probability of discounted aggregate claims for renewal risk model within finite horizon is obtained. The result extends the corresponding conclusions of related references.
