Health expenditure of employees versus self-employed individuals; a 5-year study.
It is unclear to what extent self‐employed choose to become self‐employed.
This study aimed to compare the health care expenditures—as a proxy for
health—of self‐employed individuals in the year before they started their
business, to that of employees. Differences by sex, age, and industry were
studied. In total, 5,741,457 individuals aged 25–65 years who were listed in the
tax data between 2010 and 2015 with data on their health insurance claims
were included. Self‐employed and employees were stratified according to sex,
age, household position, personal income, region, and industry for each of the
years covered. Weighted linear regression was used to compare health care
expenditures in the preceding (year x–1) between self‐employed and employees (in year x). Compare
Vaccination willingness and educational level
Vaccination is an important part of the fight against COVID-19 virus. A predictor of the proportion of people who will actually take a vaccination is the willingness to vaccinate among the population. Literature shows that vaccination willingness among people with lower socioeconomic status is lower than among other groups. In this contribution we describe to what extent this is also the case in the Netherlands and show how risk perception, trust in the effects and safety of the vaccine, and health literacy may be related to this. Finally, we highlight a number of intervention strategies that can make a positive contribution to vaccination willingness among lower educated groups
In vivo evaluation of a vibration analysis technique for the per-operative monitoring of the fixation of hip prostheses
<p>Abstract</p> <p>Background</p> <p>The per-operative assessment of primary stem stability may help to improve the performance of total hip replacement. Vibration analysis methods have been successfully used to assess dental implant stability, to monitor fracture healing and to measure bone mechanical properties. The objective of the present study was to evaluate in vivo a vibration analysis-based endpoint criterion for the insertion of the stem by successive surgeon-controlled hammer blows.</p> <p>Methods</p> <p>A protocol using a vibration analysis technique for the characterisation of the primary bone-prosthesis stability was tested in 83 patients receiving a custom-made, intra-operatively manufactured stem prosthesis. Two groups were studied: one (n = 30) with non cemented and one (n = 53) with partially cemented stem fixation. Frequency response functions of the stem-femur system corresponding to successive insertion stages were compared.</p> <p>Results</p> <p>The correlation coefficient between the last two frequency response function curves was above 0.99 in 86.7% of the non cemented cases. Lower values of the final correlation coefficient and deviations in the frequency response pattern were associated with instability or impending bone fracture. In the cases with a partially cemented stem an important difference in frequency response function between the final stage of non cemented trial insertion and the final cemented stage was found in 84.9% of the cases. Furthermore, the frequency response function varied with the degree of cement curing.</p> <p>Conclusion</p> <p>The frequency response function change provides reliable information regarding the stability evolution of the stem-femur system during the insertion. The protocol described in this paper can be used to accurately detect the insertion end point and to reduce the risk for intra-operative fracture.</p
Ethnic Health Care Advisors: A Good Strategy to Improve the Access to Health Care and Social Welfare Services for Ethnic Minorities?
Empirical studies indicate that ethnic minorities have limited access to health care and welfare services compared with the host population. To improve this access, ethnic health care (HC) advisors were introduced in four districts in Amsterdam, the Netherlands. HC advisors work for all health care and welfare services and their main task is to provide information on health care and welfare to individuals and groups and refer individuals to services. Action research was carried out over a period of 2 years to find out whether and how this function can contribute to improve access to services for ethnic minorities. Information was gathered by semi-structured interviews, analysing registration forms and reports, and attending meetings. The function’s implementation and characteristics differed per district. The ethnicity of the health care advisors corresponded to the main ethnic groups in the district: Moroccan and Turkish (three districts) and sub-Sahara African and Surinamese (one district). HC advisors reached many ethnic inhabitants (n = 2,224) through individual contacts. Half of them were referred to health care and welfare services. In total, 576 group classes were given. These were mostly attended by Moroccan and Turkish females. Outreach activities and office hours at popular locations appeared to be important characteristics for actually reaching ethnic minorities. Furthermore, direct contact with a well-organized back office seems to be important. HC advisors were able to reach many ethnic minorities, provide information about the health care and welfare system, and refer them to services. Besides adapting the function to the local situation, some general aspects for success can be indicated: the ethnic background of the HC advisor should correspond to the main ethnic minority groups in the district, HC advisors need to conduct outreach work, there must be a well-organized back office to refer clients to, and there needs to be enough commitment among professionals of local health and welfare services
Circulating adrenomedullin estimates survival and reversibility of organ failure in sepsis: the prospective observational multinational Adrenomedullin and Outcome in Sepsis and Septic Shock-1 (AdrenOSS-1) study
Background: Adrenomedullin (ADM) regulates vascular tone and endothelial permeability during sepsis. Levels of circulating biologically active ADM (bio-ADM) show an inverse relationship with blood pressure and a direct relationship with vasopressor requirement. In the present prospective observational multinational Adrenomedullin and Outcome in Sepsis and Septic Shock 1 (, AdrenOSS-1) study, we assessed relationships between circulating bio-ADM during the initial intensive care unit (ICU) stay and short-term outcome in order to eventually design a biomarker-guided randomized controlled trial. Methods: AdrenOSS-1 was a prospective observational multinational study. The primary outcome was 28-day mortality. Secondary outcomes included organ failure as defined by Sequential Organ Failure Assessment (SOFA) score, organ support with focus on vasopressor/inotropic use, and need for renal replacement therapy. AdrenOSS-1 included 583 patients admitted to the ICU with sepsis or septic shock. Results: Circulating bio-ADM levels were measured upon admission and at day 2. Median bio-ADM concentration upon admission was 80.5 pg/ml [IQR 41.5-148.1 pg/ml]. Initial SOFA score was 7 [IQR 5-10], and 28-day mortality was 22%. We found marked associations between bio-ADM upon admission and 28-day mortality (unadjusted standardized HR 2.3 [CI 1.9-2.9]; adjusted HR 1.6 [CI 1.1-2.5]) and between bio-ADM levels and SOFA score (p < 0.0001). Need of vasopressor/inotrope, renal replacement therapy, and positive fluid balance were more prevalent in patients with a bio-ADM > 70 pg/ml upon admission than in those with bio-ADM ≤ 70 pg/ml. In patients with bio-ADM > 70 pg/ml upon admission, decrease in bio-ADM below 70 pg/ml at day 2 was associated with recovery of organ function at day 7 and better 28-day outcome (9.5% mortality). By contrast, persistently elevated bio-ADM at day 2 was associated with prolonged organ dysfunction and high 28-day mortality (38.1% mortality, HR 4.9, 95% CI 2.5-9.8). Conclusions: AdrenOSS-1 shows that early levels and rapid changes in bio-ADM estimate short-term outcome in sepsis and septic shock. These data are the backbone of the design of the biomarker-guided AdrenOSS-2 trial. Trial registration: ClinicalTrials.gov, NCT02393781. Registered on March 19, 2015

Genomic organisation of the Mal d 1 gene cluster on linkage group 16 in apple
European populations exhibit progressive sensitisation to food allergens, and apples are one of the foods for which sensitisation is observed most frequently. Apple cultivars vary greatly in their allergenic characteristics, and a better understanding of the genetic basis of low allergenicity may therefore allow allergic individuals to increase their fruit intake. Mal d 1 is considered to be a major apple allergen, and this protein is encoded by the most complex allergen gene family. Not all Mal d 1 members are likely to be involved in allergenicity. Therefore, additional knowledge about the existence and characteristics of the different Mal d 1 genes is required. In the present study, we investigated the genomic organisation of the Mal d 1 gene cluster in linkage group 16 of apple through the sequencing of two bacterial artificial chromosome clones. The results provided new information on the composition of this family with respect to the number and orientation of functional and pseudogenes and their physical distances. The results were compared with the apple and peach genome sequences that have recently been made available. A broad analysis of the whole apple genome revealed the presence of new genes in this family, and a complete list of the observed Mal d 1 genes is supplied. Thus, this study provides an important contribution towards a better understanding of the genetics of the Mal d 1 family and establishes the basis for further research on allelic diversity among cultivars in relation to variation in allergenicity
