[Health Promotion and Prevention of Non-Communicable Diseases by Public Health Departments in Baden-Württemberg during the COVID-19 Pandemic: Results of an Online Survey]. / Gesundheitsförderung und Prävention nicht-übertragbarer Erkrankungen durch Gesundheitsämter in Baden-Württemberg während der COVID-19-Pandemie ­ Ergebnisse einer Onlinebefragung.

OBJECTIVES: Disease prevention and health promotion are among the core tasks of German public health services (Öffentlicher Gesundheitsdienst - ÖGD), particularly local public health departments (Gesundheitsämter). Little is known about the extent to which the departments were able to continue activities in the field of health promotion and prevention of non-communicable diseases (HPP-NCDs) during the COVID-19 pandemic. Using the example of public health departments in Baden-Württemberg (BW), we therefore investigated how much staff was available to the departments for HPP-NCDs services, how much staff was actually dedicated to HPP-NCDs during the COVID-19 pandemic, which HPP-NCDs activities were carried out during the pandemic, which were cancelled, and which should be resumed as a priority, according to the public health departments. METHODS: We developed a largely standardized online questionnaire for the survey of the 38 public health departments in BW. Per department one questionnaire was to be completed. The survey took place from 9/1/2022 to 11/4/2022. The data of this explorative cross-sectional study were analyzed in a descriptive-statistical manner using SPSS, version 28. RESULTS: Of the 38 departments, 34 participated in the survey (89%). Departments had a mean of 2.44 full HPP-NCDs staff as planned (median 2.00; SD 1.41; range 0.20-5.00). Under pandemic conditions, a mean of 1.23 full HPP-NCDs staff were deployed (median 0.95; SD 1.24; range 0.00-4.50). Respondents gave examples of 61 HPP-NCDs activities that were conducted under pandemic conditions, and they described 69 HPP-NCDs activities that had to be cancelled. Of the latter, respondents felt that 40 should be resumed as a matter of highest priority. Analysis of the priority activities to be resumed reveals characteristic differences: e. g., resumption of structural prevention activities was viewed more frequently as a matter of hightest priority than resumption of behavioral prevention activities. CONCLUSIONS: During the pandemic, local public health departments in BW deployed, on average, actually only half of their full staff allocated as planned to HPP-NCDs. Comparing different categories of HPP-NCDs activities (cancelled during the pandemic) in terms of the relative frequency with which their resumption is viewed as matter of highest priority, characteristic differences can be observed. It remains an open question which conclusions can be drawn from such differences.

[Information on health promotion and prevention on the websites of Baden-Württemberg's public health services-a first approach]. / Informationen zu Gesundheitsförderung und Prävention auf den Webseiten baden-württembergischer Gesundheitsämter ­ eine erste Annäherung.

BACKGROUND: Health promotion and prevention are core tasks of German public health services (Öffentlicher Gesundheitsdienst). Health communication is, among other things, central to their effectiveness. As the Internet has become an important source of health information and public health services are increasingly in the public eye, their websites are gaining more focus. We therefore investigated how public health services present topics on health promotion and prevention of non-communicable diseases (HPP-NCDs) on their websites. METHODS: The websites of the 38 public health service departments in Baden-Wuerttemberg were examined using qualitative content analysis from June to October 2022. The presentation of the HPP-NCDs topic on the websites as well as the relevant measures were documented. For each measure/activity the addressed target group, the topic, and the type of intervention was collected. RESULTS: The HPP-NCDs topic is addressed on all websites (n = 38); however, the presentation style is heterogeneous. A total of 243 HPP-NCDs measures/activities were identified across the 38 websites. There was a broad spectrum of topics, target groups, and types of intervention used in the measures/activities presented. DISCUSSION: The study shows an extensive but heterogeneous presentation of HPP-NCDs on the websites of public health services. In doing so, they are caught between the requirements of public relations and health information. The use of synergy effects through the joint promotion of nationally relevant informational materials and measures could be beneficial for public health services.

Global myocardial oedema in resuscitated out-of-hospital cardiac arrest patients assessed by cardiac magnetic resonance: a pilot study.

AIMS: Myocardial dysfunction is well described after out-of-hospital cardiac arrest (OHCA); however, the underlying mechanisms are not yet understood. We hypothesized that this dysfunction is associated to a global myocardial oedema. Using cardiac magnetic resonance (CMR), we assessed the presence of such oedema early after successful resuscitation from OHCA. METHODS AND RESULTS: Comatose patients resuscitated from OHCA and admitted to the cardiac intensive care unit were consecutively included and underwent CMR in general anaesthesia within 36 h after cardiac arrest with anaesthetic support. To assess global myocardial oedema, T1 and T2 segmented maps were generated from three representative short-axis slices, and values from each segment were then used to determine a mean global T1 and T2 time for each patient. Healthy subjects were used as controls. CMR was obtained in 16 patients and compared with nine controls. The OHCA patients were 60 ± 9 years old, and acute myocardial infarction (MI) was diagnosed in six cases. On admission, left ventricular ejection fraction assessed by transthoracic echocardiography was 35 ± 15%, and this improved significantly to 43 ± 14% during hospitalization (P < 0.05). Mean global T1 and T2 time was significantly higher in OHCA patients compared with the control group (1071 ms vs. 999 ms, P = 0.002, and 52 ms vs. 46 ms, P < 0.001, respectively), and this difference remained significant when segments involved in the MI were excluded. CONCLUSION: Assessed with CMR, we for the first time document an early global myocardial oedema in patients successfully resuscitated from OHCA.

Association between inflammatory markers and survival in comatose, resuscitated out-of-hospital cardiac arrest patients.

OBJECTIVES: Prognostication after out-of-hospital cardiac arrest (OHCA) remains challenging. The inflammatory response after OHCA has been associated with increased mortality. This study investigates the associations and predictive value between inflammatory markers and outcome in resuscitated OHCA patients. DESIGN: The study is based on post hoc analyses of a double-blind controlled trial, where resuscitated OHCA patients were randomized to receive either exenatide or placebo. Blood was analyzed for levels of inflammatory markers the day following admission. Primary endpoint was time to death for up to 180 days. Secondary endpoints included 180-day mortality and poor neurological outcome after 180 days, defined as a cerebral performance category (CPC) of 3 to 5. RESULTS: Among 110 included patients we found significant associations between higher leucocyte quartile and increasing mortality in univariable analysis (OR 2.6 (95%CI 1.6-4.2), p < .001), as well as in multivariable analysis (OR 2.1 (95%CI 1.1-4.0), p = .02). A significant association was found between higher neutrophil quartile and increasing mortality in univariable analysis (OR 3.0 (95%CI 1.8-5.0), p < .001) as well as multivariable analysis (OR 2.4 (95%CI 1.2-4.6), p = .01). Leucocyte and neutrophil levels were predictive of poor outcome after 180 days with area under the receiver operating characteristics curves of 0.79 and 0.81, respectively. We found no associations between CRP and lymphocyte levels versus outcome. CONCLUSIONS: Total leucocyte count and neutrophil levels measured the first day following OHCA were significantly associated with 180-day all-cause mortality and may potentially act as early predictors of outcome.

Admission Leukocyte Count is Associated with Late Cardiogenic Shock Development and All-Cause 30-Day Mortality in Patients with St-Elevation Myocardial Infarction.

BACKGROUND: Thirty-day mortality in ST-elevation myocardial infarction (STEMI) patients is primarily driven by cardiogenic shock (CS). High neutrophil counts and high neutrophil/lymphocyte ratios (NLR) have previously been associated with mortality in STEMI patients; however, there is only sparse knowledge regarding their association with CS. PURPOSE: We sought to assess the associations between neutrophil count and NLR with the development of CS as well as 30-day mortality in STEMI patients. METHODS: Patients admitted with STEMI at two tertiary Heart Centres throughout 1 year were included in the study and stratified into quartiles according to the level of leukocyte count upon admission. The primary endpoint was development of CS both before (early CS) and after leaving the catheterization laboratory (late CS). The secondary endpoint was all-cause 30-day mortality. RESULTS: A total of 1,892 STEMI patients were included, whereof 194 (10%) developed CS while 122 (6.4%) died within 30 days. Patients in the highest quartile of neutrophils (OR: 2.54; 95% CI: 1.40-4.60; P = 0.002) and NLR (OR: 3.64; 95% CI: 2.02-6.54; P<0.0001) were at increased risk of developing late CS compared with patients in the lower quartiles, whereas there was no risk difference across quartiles regarding development of early CS. Both biomarkers correlated strongly to an increased 30-day mortality (plogrank<0.0001) and, moreover, a high level of neutrophils was independently associated with 30-day mortality (HR: 1.95; 95% CI: 1.25-3.03; P = 0.003). CONCLUSION: High levels of neutrophils and a high NLR upon admission for STEMI were independently associated with an increased risk of developing late CS and, additionally, both biomarkers showed association to 30-day mortality.

Estimating fetal cholesterol synthesis rates by cord blood analysis in intrauterine growth restriction and normally grown fetuses.

BACKGROUND: Cholesterol is an essential component in human development. In fetuses affected by intrauterine growth restriction (IUGR), fetal blood cholesterol levels are low. Whether this is the result of a reduced materno-fetal cholesterol transport, or due to low fetal de novo synthesis rates, remains a matter of debate. By analyzing cholesterol interbolites and plant sterols we aimed at deeper insights into transplacental cholesterol transport and fetal cholesterol handling in IUGR with potential targets for future therapy. We hypothesized that placental insufficiency results in a diminished cholesterol supply to the fetus. METHODS: Venous umbilical cord sera were sampled post-partum from fetuses delivered between 24 weeks of gestation and at full term. IUGR fetuses were matched to 49 adequate-for-age delivered preterm and term neonates (CTRL) according to gestational age at delivery. Cholesterol was measured by gas chromatography-flame ionization detection using 5a-cholestane as internal standard. Cholesterol precursors and synthesis markers, such as lanosterol, lathosterol, and desmosterol, the absorption markers, 5α-cholestanol and plant sterols, such as campesterol and sitosterol, as well as enzymatically oxidized cholesterol metabolites (oxysterols), such as 24S- or 27-hydroxycholesterol, were analyzed by gas chromatography-mass spectrometry, using epicoprostanol as internal standard for the non-cholesterol sterols and deuterium labeled oxysterols for 24S- and 27-hydroxycholesterol. RESULTS: Mean cholesterol levels were 25% lower in IUGR compared with CTRL (p < 0.0001). Lanosterol and lathosterol to cholesterol ratios were similar in IUGR and CTRL. In relation to cholesterol mean, desmosterol, 24S-hydroxycholesterol, and 27-hydroxycholesterol levels were higher by 30.0, 39.1 and 60.7%, respectively, in IUGR compared to CTRL (p < 0.0001). Equally, 5α-cholestanol, campesterol, and ß-sitosterol to cholesterol ratios were higher in IUGR than in CTRL (17.2%, p < 0.004; 33.5%, p < 0.002; 29.3%, p < 0.021). CONCLUSIONS: Cholesterol deficiency in IUGR is the result of diminished fetal de novo synthesis rates rather than diminished maternal supply. However, increased oxysterol- and phytosterol to cholesterol ratios suggest a lower sterol elimination rate. This is likely caused by a restricted hepatobiliary function. Understanding the fetal cholesterol metabolism is important, not only for neonatal nutrition, but also for the development of strategies to reduce the known risk of future cardiovascular diseases in the IUGR fetus.

Lack of tone in mouse small mesenteric arteries leads to outward remodeling, which can be prevented by prolonged agonist-induced vasoconstriction.

Inward remodeling of resistance vessels is an independent risk factor for cardiovascular events. Thus far, the remodeling process remains incompletely elucidated, but the activation level of the vascular smooth muscle cell appears to play a central role. Accordingly, previous data have suggested that an antagonistic and supposedly beneficial response, outward remodeling, may follow prolonged vasodilatation. The present study aimed to determine whether 1) outward remodeling follows 3 days of vessel culture without tone, 2) a similar response can be elicited in a much shorter 4-h timeframe, and, finally, 3) whether a 4-h response can be prevented or reversed by the presence of vasoconstrictors in the medium. Cannulated mouse small mesenteric arteries were organocultured for 3 days in the absence of tone, leading to outward remodeling that continued throughout the culture period. In more acute experiments in which cannulated small mesenteric arteries were maintained in physiological saline without tone for 4 h, we detected a similar outward remodeling that proceeded at a rate several times faster. In the 4-h experimental setting, continuous vasoconstriction to ~50% tone by abluminal application of UTP or norepinephrine + neuropeptide Y prevented outward remodeling but did not cause inward remodeling. Computational modeling was used to simulate and interpret these findings and to derive time constants of the remodeling processes. It is suggested that depriving resistance arteries of activation will lead to eutrophic outward remodeling, which can be prevented by vascular smooth muscle cell activation induced by prolonged vasoconstrictor exposure. NEW & NOTEWORTHY We have established an effective 4-h method for studying outward remodeling in pressurized mouse resistance vessels ex vivo and have determined conditions that block the remodeling response. This allows for investigating the subtle but clinically highly relevant phenomenon of outward remodeling while avoiding both laborious 3-day organoid culture of cannulated vessels and in vivo experiments lasting several weeks.
