Spatial characteristics of non-communicable diseases and their associations to social conditions in a large urban cohort in Germany-Results from the Hamburg City Health Study. PLoS One 2024; 19:e0301475. [PMID: 38593150 PMCID: PMC11003678 DOI: 10.1371/journal.pone.0301475] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 03/07/2024] [Indexed: 04/11/2024] Open
Abstract
BACKGROUND Non-communicable diseases (NCDs) are responsible for many deaths. They are associated with several modifiable and metabolic risk factors and are therefore prone to significant regional variations on different scales. However, only few intra-urban studies examined spatial variation in NCDs and its association with social circumstances, especially in Germany. Thus, the present study aimed to identify associations of personal risk factors and local social conditions with NCDs in a large German city. METHODS This study is based on a population-based cohort of the Hamburg City Health Study including 10,000 probands. Six NCDs were analyzed (chronic obstructive pulmonary disease [COPD], coronary heart disease [CHD], diabetes mellitus, heart failure, depression, and hypertension) in 68 city district clusters. As risk factors, we considered socio-demographic variables (age, sex, education) and risk behaviour variables (smoking, alcohol consumption). Logistic regression analyses identified associations between the district clusters and the prevalence rates for each NCD. Regional variation was detected by Gini coefficients and spatial cluster analyses. Local social condition indexes were correlated with prevalence rates of NCDs on city district level and hot-spot analyses were performed for significant high or low values. RESULTS The analyses included 7,308 participants with a mean age of 63.1 years (51.5% female). The prevalence of hypertension (67.6%) was the highest. Risk factor associations were identified between smoking, alcohol consumption and education and the prevalence of NCDs (hypertension, diabetes, and COPD). Significant regional variations were detected and persisted after adjusting for personal risk factors. Correlations for prevalence rates with the local social conditions were significant for hypertension (r = 0.294, p < 0.02), diabetes (r = 0.259, p = 0.03), and COPD (r = 0.360, p < 0.01). CONCLUSIONS The study shows that regional differences in NCD prevalence persist even after adjusting for personal risk factors. This highlights the central role of both personal socio-economic status and behaviors such as alcohol and tobacco consumption. It also highlights the importance of other potential regional factors (e.g. the environment) in shaping NCD prevalence. This knowledge helps policy- and decision-makers to develop intervention strategies.

Evidence from the Hamburg City Health Study (HCHS). BMC Health Serv Res 2024; 24:32. [PMID: 38178105 PMCID: PMC10768441 DOI: 10.1186/s12913-023-10490-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Accepted: 12/18/2023] [Indexed: 01/06/2024] Open
Abstract
BACKGROUND The COVID-19 pandemic engendered numerous societal and economic challenges in addition to health-related concerns. Maintenance of healthcare utilization assumed immense significance during this period. However, few studies have examined the association between loneliness and cancelled medical appointments during the COVID-19 pandemic. This study aimed to examine whether medical appointments are less likely to be cancelled with increased loneliness during a pandemic. We analyzed the association between loneliness and both patient- and provider-initiated appointment cancellations. METHODS Cross-sectional data from the Hamburg City Health Study (HCHS) were collected during April 2020-November 2021. The analytical sample included 1,840 participants with an average age of 55.1 years (standard deviation: 6.5, range 45-76 years). Medical appointments cancelled by individuals-medical appointments in general, and GP, specialist, and dentist appointments-and appointments cancelled by healthcare providers served as outcome measures. Loneliness was quantified using a single item ranging from 0 to 10. Accordingly, we created empirical loneliness tertiles. Covariates were selected based on the Andersen model. Several penalized maximum likelihood logistic regressions were utilized to examine the association between loneliness and cancellation of medical appointments during the COVID-19 pandemic. RESULTS The penalized maximum likelihood logistic regressions showed that, compared to individuals in the lowest loneliness tertiles, individuals in the other two tertiles reported a higher chance of medical appointments cancellation by individuals, particularly driven by cancelled GP appointments. Except for age and sex, none of the covariates were comparably associated with the outcomes. When appointments cancelled by healthcare providers served as outcomes, only a higher number of chronic conditions was significantly positively associated with it. CONCLUSIONS Individuals scoring higher in loneliness had a greater chance of cancelling medical (particularly GP) appointments. This may contribute to a potential cascade of loneliness and skipped medical appointments in the future, resulting in adverse health outcomes over the medium-to-long term. Future research should examine whether lonely people are more likely to lack the social motivation to visit the doctor.

Cross-Sectional Association of Dietary Patterns and Supplement Intake with Presence and Gray-Scale Median of Carotid Plaques-A Comparison between Women and Men in the Population-Based Hamburg City Health Study. Nutrients 2023; 15:1468. [PMID: 36986198 PMCID: PMC10054689 DOI: 10.3390/nu15061468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 03/15/2023] [Accepted: 03/16/2023] [Indexed: 03/30/2023] Open
Abstract
This population-based cross-sectional cohort study investigated the association of the Mediterranean and DASH (Dietary Approach to Stop Hypertension) diet as well as supplement intake with gray-scale median (GSM) and the presence of carotid plaques comparing women and men. Low GSM is associated with plaque vulnerability. Ten thousand participants of the Hamburg City Health Study aged 45-74 underwent carotid ultrasound examination. We analyzed plaque presence in all participants plus GSM in those having plaques (n = 2163). Dietary patterns and supplement intake were assessed via a food frequency questionnaire. Multiple linear and logistic regression models were used to assess associations between dietary patterns, supplement intake and GSM plus plaque presence. Linear regressions showed an association between higher GSM and folate intake only in men (+9.12, 95% CI (1.37, 16.86), p = 0.021). High compared to intermediate adherence to the DASH diet was associated with higher odds for carotid plaques (OR = 1.18, 95% CI (1.02, 1.36), p = 0.027, adjusted). Odds for plaque presence were higher for men, older age, low education, hypertension, hyperlipidemia and smoking. In this study, the intake of most supplements, as well as DASH or Mediterranean diet, was not significantly associated with GSM for women or men. Future research is needed to clarify the influence, especially of the folate intake and DASH diet, on the presence and vulnerability of plaques.

Abstract
In search for immunological correlates of protection against acute coronavirus disease 2019 (COVID-19) there is a need for high through-put assays for cell-mediated immunity (CMI) to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We established an interferon-γ release assay -based test for detection of CMI against SARS-CoV-2 spike (S) or nucleocapsid (NC) peptides. Blood samples obtained from 549 healthy or convalescent individuals were measured for interferon-γ (IFN-γ) production after peptide stimulation using a certified chemiluminescence immunoassay. Test performance was calculated applying cutoff values with the highest Youden indices in receiver-operating-characteristics curve analysis and compared to a commercially available serologic test. Potential confounders and clinical correlates were assessed for all test systems. 522 samples obtained from 378 convalescent in median 298 days after PCR-confirmed SARS-CoV-2 infection and 144 healthy control individuals were included in the final analysis. CMI testing had a sensitivity and specificity of up to 89% and 74% for S peptides and 89% and 91% for NC peptides, respectively. High white blood cell counts correlated negatively with IFN-γ responses but there was no CMI decay in samples obtained up to one year after recovery. Severe clinical symptoms at time of acute infection were associated with higher measures of adaptive immunity and reported hair loss at time of examination. This laboratory-developed test for CMI to SARS-CoV-2 NC peptides exhibits excellent test performance, is suitable for high through-put routine diagnostics, and should be evaluated for clinical outcome prediction in prospective pathogen re-exposure.

Abstract
INTRODUCTION The COVID-19 pandemic is also impacting the medical care for other diseases. The extent to which people with chronic diseases are affected by the suspension of medical services is investigated-differentiating between patient and provider perspectives. METHOD A cross-sectional study was conducted based on data from the longitudinal Hamburg City Health Study (HCHS). The study population was all HCHS participants (a sample of the population of Hamburg, 45-74 years) between April 2020 and November 2021. Utilisation of medical services was collected via the "COVID-19-module" of the HCHS. The chronic conditions included cardiovascular disease, kidney and lung disease, cancer and diabetes mellitus; analyses were descriptive and multivariate. RESULTS Of the 2047 participants, 47.9% had at least one previous illness. Of those with pre-existing conditions, 21.4% had at least one healthcare service suspended or an appointment cancelled. In addition, 15.4% stated that they decided by themselves not to attend a doctor's appointment. Specialist care services (43.8% of all cancellations) were cancelled more frequently than general practitioner care (16.6%). After adjustment for age, gender and education, lung disease (OR 1.80; p < 0.008) and cancer (OR 2.33; p < 0.001) were found to be independent risk factors for appointment cancellations by healthcare providers. Of cancellations by patients, 42.2% were due to their fear of an infection with the coronavirus SARS-CoV‑2. DISCUSSION Health policy and the media are faced with the challenge of dealing with fears of infection in the population in such a way that they do not lead to an avoidance of necessary care services.

Detection of stage I HPV-driven oropharyngeal cancer in asymptomatic individuals in the Hamburg City Health Study using HPV16 E6 serology - A proof-of-concept study. EClinicalMedicine 2022; 53:101659. [PMID: 36147627 PMCID: PMC9486032 DOI: 10.1016/j.eclinm.2022.101659] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 08/19/2022] [Accepted: 08/30/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The lack of detectable precancerous lesions poses challenges to the early detection of human papillomavirus-driven oropharyngeal cancer (HPV-OPC). Antibodies against HPV16 early proteins, especially E6, are uniquely sensitive and specific biomarkers detectable years prior to HPV-OPC diagnosis. Thus, HPV16 early protein serology warrants clinical investigation for HPV-OPC screening. METHODS Using multiplex serology, we analyzed HPV16 serum antibodies of the first 5000 participants (n=4,424 sera, recruited 2016-2017) of the Hamburg City Health Study, a population-based prospective cohort (45-74 years). Participants seropositive for HPV16 E6 and at least one additional early protein (E1, E2, E7) were considered at high risk for HPV-OPC development and invited to six-monthly non-invasive head and neck follow-up (FU) examinations (visual inspection, endoscopy, ultrasonography, performed 2019-2020). Participants with suspicious lesions were examined by magnetic resonance imaging and panendoscopy with biopsy. Histologically confirmed OPC cases were treated according to standard of care. FINDINGS In total, 35 out of 4,424 study participants (0·8%, 95% confidence interval (CI) 0·6-1·1%) were HPV16 E6 seropositive. Among these, eleven (0·3%, 95%CI 0·1-0·5%) were considered at high risk for HPV-OPC of which nine were successfully re-contacted and invited to regular clinical FU examinations. Two males and one female were diagnosed with stage I HPV-OPC within 1·3 years of clinical FU (3-4 years after initial blood draw), representing one diagnosis of prevalent advanced disease, one incident diagnosis of advanced disease, and one incident diagnosis of early disease. The remaining participants showed no detectable signs of cancer, and undergo regular examinations (median clinical FU: 1·0 years, median total FU from blood draw to last clinical FU visit: 4·7 years). INTERPRETATION HPV16 early antibodies allowed identifying three asymptomatic stage I HPV-OPC patients, out of eleven participants considered at high risk. However, two of the three cases already showed signs of advanced disease at diagnosis. Targeting multiple early proteins may considerably improve the positive predictive value of HPV16 serology and may have clinical utility for HPV-OPC screening. FUNDING This work was funded by DKFZ and UKE intramural funding.

Abstract
The aim of this work was to systematically collect all previously published population-based epidemiological data on skin diseases in Germany. The present part 2 of the publication series deals with non-infectious skin diseases. The results on cutaneous tumor diseases (part 1) and infectious skin diseases (part 3) form the other parts of this publication series. A systematic literature search was performed using PubMed/MEDLINE for the period of the last 15 years. With the aim of including all dermatologic diseases, a diagnostic list was developed based on the ICD-11 catalogue. This list included 1,347 skin diseases and formed the basis for the search. The literature search yielded 4,650 hits, of which 72 were included in the synthesis. Among them were 37 publications on non-infectious skin diseases. Among these, psoriasis and atopic eczema were the most common. The highest lifetime prevalence was found for acne. This work is the first systematic literature review that aimed to report all available epidemiological data on skin diseases in Germany. It was found that representative data on many non-infectious diseases are not yet available. Among the included studies, there was a high heterogeneity regarding the methodology. Nevertheless, the utility of these epidemiological data is wide-ranging and can serve as a reference of various epidemiological questions.

Abstract
AIMS Long-term sequelae may occur after SARS-CoV-2 infection. We comprehensively assessed organ-specific functions in individuals after mild to moderate SARS-CoV-2 infection compared with controls from the general population. METHODS AND RESULTS Four hundred and forty-three mainly non-hospitalized individuals were examined in median 9.6 months after the first positive SARS-CoV-2 test and matched for age, sex, and education with 1328 controls from a population-based German cohort. We assessed pulmonary, cardiac, vascular, renal, and neurological status, as well as patient-related outcomes. Bodyplethysmography documented mildly lower total lung volume (regression coefficient -3.24, adjusted P = 0.014) and higher specific airway resistance (regression coefficient 8.11, adjusted P = 0.001) after SARS-CoV-2 infection. Cardiac assessment revealed slightly lower measures of left (regression coefficient for left ventricular ejection fraction on transthoracic echocardiography -0.93, adjusted P = 0.015) and right ventricular function and higher concentrations of cardiac biomarkers (factor 1.14 for high-sensitivity troponin, 1.41 for N-terminal pro-B-type natriuretic peptide, adjusted P ≤ 0.01) in post-SARS-CoV-2 patients compared with matched controls, but no significant differences in cardiac magnetic resonance imaging findings. Sonographically non-compressible femoral veins, suggesting deep vein thrombosis, were substantially more frequent after SARS-CoV-2 infection (odds ratio 2.68, adjusted P < 0.001). Glomerular filtration rate (regression coefficient -2.35, adjusted P = 0.019) was lower in post-SARS-CoV-2 cases. Relative brain volume, prevalence of cerebral microbleeds, and infarct residuals were similar, while the mean cortical thickness was higher in post-SARS-CoV-2 cases. Cognitive function was not impaired. Similarly, patient-related outcomes did not differ. CONCLUSION Subjects who apparently recovered from mild to moderate SARS-CoV-2 infection show signs of subclinical multi-organ affection related to pulmonary, cardiac, thrombotic, and renal function without signs of structural brain damage, neurocognitive, or quality-of-life impairment. Respective screening may guide further patient management.

Abstract
Epidemiological data are of great importance for the identification of health care needs, the detection of gaps in care, the development of targeted prevention measures, and for the optimization of resource allocation. The aim of this work was to systematically collect all previously published population-based epidemiological data on skin diseases in Germany. The present part 1 of the publication series deals with tumor diseases of the skin. The results on non-infectious (part 2) and infectious skin diseases (part 3) form the other parts of this publication series. A systematic search of the literature spanning the last 15 years was conducted using the PubMed/MEDLINE database. With the aim of including all dermatologic diseases, a diagnostic list was developed based on the ICD-11 catalogue. This list included 1,347 skin diseases and formed the basis for the search. The literature search yielded 4,650 publications. After two-stage screening, 72 studies on 43 different skin diseases were included in the synthesis. Among them were 30 publications on cutaneous tumor diseases, the majority was related to malignant melanoma. This work is the first systematic literature review that aimed to report all available epidemiological data on skin diseases in Germany. In terms of study characteristics, a high heterogeneity was found for the different skin diseases. Even though the methodology of the included epidemiological studies varied considerably, the usefulness of these epidemiological data is extremely wide-ranging. Thus, this work can serve as a reference for various epidemiological questions.

Abstract
BACKGROUND AND OBJECTIVES The aim of the present study was to determine the prevalence and incidence of skin cancer. PATIENTS AND METHODS We calculated prevalence and incidence for cutaneous melanoma (CM) and non-melanoma skin cancer (NMSC) in 2012 in Germany, using claims data of 2.1 million insured persons. In order to allow statements concerning differences between subgroups, we calculated 95 % confidence intervals. Finally, we standardized prevalence and incidence with regard to the German population. RESULTS The prevalence and incidence of CM amounted to 0.12 % and 0.04 % and increased with age. For NMSC these measures were 0.65 % and 0.15 %. Of the prevalent and incident patients, 88.9 % and 87.4 % (CM) and 99.4 % and 98.8 % (NMSC) respectively were at early stages. A projection on the whole population resulted in 75,419 persons affected by CM and 376,004 persons affected by NMSC, including 24,075 (CM) and 84,618 (NMSC) incident patients. CONCLUSIONS In this study, we defined epidemiological measures according to the number of patients affected by skin cancer and having a medical consultation indicating a need for treatment. These results can serve in future research as a data basis for analysis of health service demand in skin cancer patients and the associated costs.

Abstract
OBJECTIVE Childhood maltreatment (CM) plays an important role in the aetiology and course of psychotic disorders and is associated with characteristics that could be relevant for treatment. We aimed to conduct a systematic review and meta-analysis on the association between CM and treatment outcome in psychotic disorders. METHODS Treatment outcome was defined as change in psychotic symptoms or in social or occupational functioning between first and last reported measurement in the course of a pharmacological and/or psychological treatment. RESULTS Twelve treatment results from seven studies (636 patients, average treatment duration: 59.2 weeks) were included. CM was related to poorer treatment outcomes in psychotic disorders (OR = 1.51, 95% CI = [1.08, 2.10]). There is evidence that this association might increase with illness duration and increasing age and might be stronger in schizophrenia samples. CONCLUSIONS Childhood maltreatment is highly understudied with regard to treatment outcome in psychotic disorders. The need for more studies is emphasized by the fact that this meta-analysis reveals evidence for a poorer treatment response in patients with CM. If this association is confirmed, the identification of patients with CM and the consideration of associated clinical and biological conditions could contribute to improve treatment outcome in psychotic disorders.

Abstract
Many patients with a visible chronic skin disease experience discrimination and stigmatization. This results in psychosocial impairments in addition to the burden of disease and emphasizes the urgency to implement effective stigma-reduction strategies. To synthesize what is known globally about effective interventions to reduce stigma associated with visible chronic skin diseases, a systematic review was conducted. Four electronic databases were searched until May 2018. Studies evaluating interventions to reduce stigmatization in patients with visible chronic skin diseases and applying at least one stigma-related outcome measure were included. Data were extracted on study design, country, study population, outcome measures and main findings. Results were subsequently synthesized in a narrative review. Critical Appraisal Skills Programme tools were used to assess study quality. Nineteen studies were included in the review. Study design was very heterogeneous and study quality rather poor. Thirteen studies addresses patients with leprosy in low- and middle-income countries, and one study each targeted patients with onychomycosis, leg ulcer, facial disfigurement, atopic dermatitis, vitiligo and alopecia. Evaluated interventions were mainly multi-faceted incorporating more than one type of intervention. While 10 studies focused on the reduction in self-stigma and 4 on the reduction in public stigma, another 5 studies aimed at reducing both. The present review revealed a lack of high-quality studies on effective approaches to reduce stigmatization of patients with visible chronic skin diseases. Development and evaluation of intervention formats to adequately address stigma is essential to promote patients' health and well-being.

Abstract
BACKGROUND People affected by allergies with mild-to-moderate symptoms are often not treated adequately, despite the availability of prevention and self-therapy measures. Given their good and quick accessibility when seeking information, evidence- and web-based services that are user-friendly may strengthen a more independent way of handling an allergy and may also increase health literacy. In order for such services to be found and read, developers and providers need to know about information needs, demands and users' behavior. OBJECTIVES On which occasions does the target group search for allergy-specific information? Which preferences and demands do affected persons have regarding a web-based service? MATERIALS AND METHODS Three individual interviews and four focus groups with 37 participants (19-81 years; hay fever, n = 30; asthma, n = 17; eczema, n = 15) were conducted in four German cities. These were recorded and transcribed verbatim. A multiprofessional team developed a system for coding the texts (two independent encoders, MAXQDA analysis software). RESULTS Those who are affected usually seek information only in case of a concrete need for action. Impulses are, among others, symptoms, suggestions from the social environment, the beginning of the allergy season or an allergy-related contact with the health system. A web-based service should primarily include information about treatment options, provide individualized support for everyday life action strategies, and promote adequate self-management skills. DISCUSSION In order to promote self-management skills, a web-based service should focus on allergy symptoms, treatment options and day-to-day help.

Abstract
BACKGROUND Malignant melanoma is accounting for the vast majority of skin cancer death. The treatment and productivity loss due to morbidity or premature mortality are associated with costs for society. There are few cost-of-illness (COI) studies on malignant melanoma in European countries from societal perspective and currently there is no publication analysing the COI in all European countries. OBJECTIVES The objective of the present study was to comparatively estimate COI of malignant melanoma in the European countries based on an identical approach. METHODS Cost information was obtained from results of a systematic literature research. For countries with no available cost information, a model for imputation of cost data was developed. Country-specific costs were modelled on the national gross domestic product, health expenditures, gross national income and epidemiological data. The adjustment for purchasing power parity allowed a comparison across countries. RESULTS Crude national costs of malignant melanoma ranged between € 1.1 million in Iceland and € 543.8 million in Germany and resulted in € 2.7 billion for all EU/EFTA states. Estimated crude costs per patient were lowest in Bulgaria (€ 6422) and highest in Luxembourg (€ 50 734). The share of direct costs varied from 3% to 26% across countries. After adjustment for the purchasing power parity costs per patient ranged between € 14 420 in Bulgaria and € 50 961 in Cyprus. Treatment expenses and morbidity costs were markedly lower for countries that entered the EU since 2004. By contrast, mortality costs were lower in countries with a high gross domestic product per capita. CONCLUSION In this first estimation, malignant melanoma induces relevant COI in Europe. There was large variation in the costs per patient due to different health care systems and expenses. Beyond decreasing patient burden, early intervention and prevention of melanoma could have a relevant potential to save costs across Europe.

Abstract
Malignant melanoma accounts for the vast majority of skin cancer deaths. Primary prevention is used to increase knowledge about skin cancer and set incentives for a change in behaviour, which leads to a decrease in cases. Primary prevention may be cost-effective or even cost saving. Cost-of-illness (COI) studies provide information on such potential savings. The purpose of this study is to give an overview on COI studies in European countries and to compare the COI in total and by cost categories. The results can be used to model potential cost savings from prevention. We conducted a systematic literature research in PubMed using the PRISMA checklist. All costs were converted into Euro and adjusted for the reference year 2012. For the ranking of countries according to their COI, all costs were adjusted for the purchasing power parity. All studies focusing on stage III-IV melanoma include information on hospital, hospice, and outpatient treatment. Costs for the treatment of advanced melanoma range between € 2972 in Italy and € 17 408 in Sweden after adjusting for purchasing power parity. Most studies on stage I-IV melanoma include costs of hospitalization, outpatient treatment and general practitioner consultation. Direct costs range from € 923 in Sweden to € 9829 in Denmark. Three articles also include information on indirect costs. Mortality costs vary between € 3511 in Sweden and € 20 408 in England, morbidity costs between € 103 in Sweden and € 4550 in England. We showed that costs for the treatment of skin cancer are moderately high in the included countries. Since after publication of the articles new costly drugs were approved in Europe, treatment costs of melanoma in Europe may be expected to have risen in the last few years, which means that there is a high expectable potential for prevention programmes to become cost-effective or even cost saving.
