Abstract
Although COVID-19 dashboards may be widely accessible, their effective use to modify the course of the pandemic through the translation of data to information, information to opinions, and opinions to decision-making is determined by their actionability. To be actionable, the information should be both fit for purpose-meeting a specific information need-and fit for use-placing the right information into the right hands at the right time and in a manner that can be understood. Recognizing the sustained importance of COVID-19 dashboards as a tool for pandemic reporting, studies to describe this landscape and take stock of experiences are of critical importance for better preparedness in future public health crises. Since early 2020, the international network of healthcare performance intelligence researchers-HealthPros-in collaboration with partners including the WHO Regional Office for Europe, have worked to systematically study the actionability of COVID-19 dashboards by comparatively studying their composition, changes over time and development process. In this presentation, results from this series of research will be summarized. Topics to be covered include: A summary of seven key features constituting actionable dashboards resulting from a descriptive assessment and scoring of 158 dashboards from more than 53 countries worldwide. Insights into changes to dashboards over the course of 2020-21 from country-specific studies in Canada, the Netherlands and Italy. Lessons learned from the perspective of COVID-19 national, governmental dashboard developers in the WHO European Region, including key enablers and barriers to the development, maintenance and evolution of dashboards over the course of the pandemic.

Abstract
Background National health information (HI) systems provide data on population health, the determinants of health and health system performance within countries. The evaluation of these systems has traditionally focused on statistical practices and procedures, and not on data use or reuse for policy and practice. This limits the capacity to assess the impact of HI systems on healthcare provision, management and policy-making. On the other hand, the field of Knowledge Translation (KT) has developed frameworks to guide evidence into practice. Methods A scoping review of the KT literature to identify the essential mechanisms and determinants of KT that could help monitor the impact of HI systems. Results We examined 79 publications and we identified over 100 different KT frameworks but none of these were focused on HI systems per se. There were specific recommendations on disseminating evidence to stakeholders at the institutional and organizational level, and on sustaining the use of evidence in practice and the broader community setting. Conclusions We developed a new model, the HI-Impact framework, in which four domains are essential for mapping the impact of national HI systems: (i) HI Evidence Quality, (ii) HI System Responsiveness, (iii) Stakeholder Engagement and (iv) Knowledge Integration. A comprehensive impact assessment of HI systems requires addressing the use of HI in public health decision-making, health service delivery and in other sectors which might have not been considered previously. Monitoring Stakeholder Engagement and Knowledge Integration certifies that the use of HI in all policies is an explicit point of assessment.

Abstract
Background The COVID-19 pandemic is a complex global public health crisis presenting clinical, organisational and system-wide challenges. Different research perspectives on health are needed in order to manage and monitor this crisis. Performance intelligence is an approach that emphasises the need for different research perspectives in supporting health systems’ decision-makers to determine policies based on well-informed choices. In this paper, we present the viewpoint of the Innovative Training Network for Healthcare Performance Intelligence Professionals (HealthPros) on how performance intelligence can be used during and after the COVID-19 pandemic. Discussion A lack of standardised information, paired with limited discussion and alignment between countries contribute to uncertainty in decision-making in all countries. Consequently, a plethora of different non-data-driven and uncoordinated approaches to address the outbreak are noted worldwide. Comparative health system research is needed to help countries shape their response models in social care, public health, primary care, hospital care and long-term care through the different phases of the pandemic. There is a need in each phase to compare context-specific bundles of measures where the impact on health outcomes can be modelled using targeted data and advanced statistical methods. Performance intelligence can be pursued to compare data, construct indicators and identify optimal strategies. Embracing a system perspective will allow countries to take coordinated strategic decisions while mitigating the risk of system collapse.A framework for the development and implementation of performance intelligence has been outlined by the HealthPros Network and is of pertinence. Health systems need better and more timely data to govern through a pandemic-induced transition period where tensions between care needs, demand and capacity are exceptionally high worldwide. Health systems are challenged to ensure essential levels of healthcare towards all patients, including those who need routine assistance. Conclusion Performance intelligence plays an essential role as part of a broader public health strategy in guiding the decisions of health system actors on the implementation of contextualised measures to tackle COVID-19 or any future epidemic as well as their effect on the health system at large. This should be based on commonly agreed-upon standardised data and fit-for-purpose indicators, making optimal use of existing health information infrastructures. The HealthPros Network can make a meaningful contribution.

Abstract
Abstract
Background
Before the regular 2015 Parliamentary elections in Croatia, we identified and analysed topics and comprehensiveness of health policies (HPs) included in political parties’ pre-election manifestos. After the loss of government confidence, we did a follow up before the 2016 preliminary elections. Here, we present a comparison of the 2015 and 2016 results.
Methods
We used the Walt-Gilson policy model for the content analysis of pre-election HPs. Five evaluators independently reviewed manifestos for HPs through four dimensions: content, actors, processes and context. HPs proposed by at least two parties were included in the final analysis and by referring to any of four dimensions for specific HP, parties scored one point (maximum of four points per HP).
Results
Seven out of the eight parties addressed healthcare topics in their manifestos, six discussed healthcare workforce and financing, while five discussed hospital systems, primary care, medical equipment and (re)organization of the healthcare. Parties earned 41% of all points for describing content, 28% for processes, 17% for actors and 14% for context of proposed HPs. Compared to the 2015 results, most comprehensively approached HPs changed to more focus on workforce and medical equipment. Topics of access to healthcare and people with disability earned significantly less points than in 2015.
Conclusions
Parties’ manifestos in both 2015 and 2016 focused on topics mostly represented in the public discourse on healthcare and daily media coverage. Financing the 2015 elections, as a consequence of a large financial restructuring effort of the hospital system at the time. Health workforce topped the 2016 elections, due to large emigration of health care professionals after legislative changes and Croatia’s accession to the EU. Parties mostly focus on the content while they less frequently address the role of processes, actors, and the context needed for successful implementation of the recommended HPs.

Abstract
We randomly assigned 17 patients with scaphoid non-union at the proximal pole to three treatment groups: (1) autologous iliac graft (n=6), (2) autologous iliac graft + osteogenic protein-1 (OP-1; n=6), and (3) allogenic iliac graft + OP-1 (n=5). Radiographic, scintigraphic, and clinical assessments were performed throughout the follow-up period of 24 months. OP-1 improved the performance of both autologous and allogenic bone implants and reduced radiographic healing time to 4 weeks compared with 9 weeks in group 1. Helical CT scans and scintigraphy showed that in OP-1-treated patients sclerotic bone was replaced by well-vascularised bone. The addition of OP-1 to allogenic bone implant equalised the clinical outcome with the autologous graft procedure. Consequently the harvesting of autologous graft can be avoided.

Abstract
Some of potential causes proposed to explain the reported increase of haematological malignancies in childhood during or after the war period in several countries include depleted uranium, chemical pollution and population mixing theory. The aim of this study was to define the population of Croatian children aged 0-14 years who were potentially exposed to each of those risks during the war and to investigate any possible association between the exposure and the incidence of haematological malignancies. The authors analyzed the data reported by the Cancer Registry of Croatia during the pre-war period (1986-1990), war period (1991-1995) and post-war period (1996-1999). In the group of 10 counties potentially exposed to depleted uranium and two counties where chemical war damage occurred, no significant difference in incidence of the studied haematological malignancies was noted in comparison to pre-war period. The incidence of lymphatic leukaemia significantly increased in four counties where population mixing had occurred during the war period, supporting the 'mixing theory'. In those counties, the incidence of Hodgkin's lymphoma decreased during and after the war. In Croatia as a whole, decreases in incidence of myeloid leukaemias during war and non-Hodgkin lymphoma after the war were noted.

Abstract
The focus was on haloperidol (central dopamine antagonist)-stomach lesion, a longly described suitable counterpart of dopamine blocker cysteamine-duodenal lesion. In this, the contribution of blockade of central/peripheral dopamine receptors and prostaglandins synthesis, along with influence of antiulcer agents was evaluated in mice. Male NMRI Hannnover mice were sacrificed 24 h after haloperidol (25 mg/kg b.w. i.p., given alone or with saline (haloperidol+saline) (i) or in combination (ii,iii)). Supporting central dopamine predominance for haloperidol stomach lesion induction, co-administration of peripheral dopamine receptor antagonist domperidone (5 mg/kg i.p.) (haloperidol+ domperidone) (ii), or prostaglandin synthesis inhibitor indomethacin (10 mg/kg s.c.) (haloperidol+ indomethacin) (iii) did not aggravate this lesion. (i) In haloperidol+saline challenged mice the lesions were inhibited by co-administration (/kg i.p.) of a gastric pentadecapeptide BPC 157, GlyGluProProProGlyLysProAlaAspAspAlaGlyLeuVal, M.W. 1419 (10 microg, 10 ng, 10 pg, but not 1 pg, 100 fg, 10 fg), bromocriptine (10 mg), omeprazole (10 mg, 100 mg, but not 1 mg). Atropine (10, 100, 200 mg), pirenzepine (10, 100, 200 mg), misoprostol (10, 100, 200 microg), pantoprazole (1, 10, 100 mg), lansoprazole (0.1, 1, 10 mg), cimetidine (10, 100, 200 mg) and ranitidine (10, 100, 200 mg) were not effective. (ii) Dopamine peripheral blockade influence: in haloperidol+domperidone mice, previously effective bromocriptine, pentadecapeptide BPC 157 (10 microg) or omeprazole (10 mg) did not attenuate stomach lesions. (iii) Prostaglandins synthesis blockade effect: in haloperidol+indomethacin mice, previously effective agents, bromocriptine or omeprazole were not active, while BPC 157 effect was only lessened.

Abstract
Exogenously administered zinc compounds have been shown to possess antiulcer activity in the development of gastric lesions. The aim of this study was to investigate the effects of zinc sulphate pretreatment of rats on cysteamine-induced duodenal ulcers and to correlate them with changes in zinc serum and tissue levels. Atomic absorption spectrophotometry was used to determine zinc serum and tissue concentrations in all animal groups. Cysteamine produced marked duodenal ulceration in control animals 24 h after application, with an increase in endogenous zinc tissue concentrations and a marked decrease in serum concentrations. Zinc sulphate (20, 40 or 80 mg kg-1) applied per os one hour prior to cysteamine application inhibited the development of duodenal lesions in a dose-related manner. The application of zinc sulphate in a single intraperitoneal (i.p.) application (80 mg kg-1) did not, however, prevent the formation of duodenal lesions. In order to assess zinc absorption from the gastrointestinal tract, one group of rats received a single oral dose of zinc sulphate (80 mg kg-1) without cysteamine application. The observations of this study seem to indicate that zinc plays an important cytoprotective role in duodenal ulcer disease.

Abstract
Exogenously administered zinc compounds have been shown to possess antiulcer activity in the development of gastric lesions. The aim of this study was to investigate the effects of zinc sulphate pretreatment of rats on cysteamine-induced duodenal ulcers and to correlate them with changes in zinc serum and tissue levels. Atomic absorption spectrophotometry was used to determine zinc serum and tissue concentrations in all animal groups. Cysteamine produced marked duodenal ulceration in control animals 24 h after application, with an increase in endogenous zinc tissue concentrations and a marked decrease in serum concentrations. Zinc sulphate (20, 40 or 80 mg kg-1) applied per os one hour prior to cysteamine application inhibited the development of duodenal lesions in a dose-related manner. The application of zinc sulphate in a single intraperitoneal (i.p.) application (80 mg kg-1) did not, however, prevent the formation of duodenal lesions. In order to assess zinc absorption from the gastrointestinal tract, one group of rats received a single oral dose of zinc sulphate (80 mg kg-1) without cysteamine application. The observations of this study seem to indicate that zinc plays an important cytoprotective role in duodenal ulcer disease.

Abstract
Exogenously administered zinc compounds have been shown to possess anti-ulcer activity against a wide variety of ulcerogenic agents, both in laboratory animal models and in human peptic ulcer disease. However, a strong possibility exists that endogenous zinc may also play an important role during noxious events by various mechanisms. Therefore, the aim of this study was to focus on the changes of endogenous zinc serum and tissue concentrations in cysteamine-induced duodenal lesions. We used atomic absorption spectrophotometry to determine the tissue and serum concentrations of zinc in normal (control) rats and those with cysteamine-induced duodenal ulcers. The results obtained in this study indicated that the onset, development and spontaneous healing of ulcer lesions were associated with certain shifts in zinc serum and tissue concentrations. Prior to ulcer formation, a significant increase was noted in serum zinc values. With the onset of duodenal lesions, zinc serum concentrations significantly decreased, while there was a significant increase in duodenal tissue concentrations when compared to healthy control animals. Zinc tissue concentrations decreased and returned to starting values by the end of the first week of spontaneous healing. This decrease in zinc tissue concentration corresponded to the healing rate of the duodenal ulcers. Serum zinc concentrations also returned to starting values within the first week period. These observations indicate and confirm that zinc could play an important role in duodenal ulcer disease and represent a natural defense system in the body.

Abstract
Describes a prototype module for data analysis of the healthcare delivery system. It consists of three main parts: data/variable selection; algorithms for the analysis of quantitative and qualitative changes in the system; and interpretation and explanation of the results. Such a module designed for primary health care has been installed on a PC in the health manager's office. Data enter the information system through the standard DBMS procedures, followed by calculating a number of different indicators and the time series, as the ordered sequences of indicators, according to demands of the manager. The last procedure is "the change analysis" with estimation of unexpected differences between and within some units, e.g. health-care teams, as well as some unexpected variabilities and trends. As an example, presents and discusses the diagnostic pattern of neurotic cases, referral patterns and preventive behaviour of GP's teams as well.

Abstract
A follow-up study of respiratory function in cotton textile workers was performed 10 yr after the original cross-sectional study (1975 to 1985). There were 35 nonsmoking female and 31 smoking male textile workers restudied from the original group of 116. The majority of those lost to follow-up had left the industry. The prevalence of byssinosis among the female workers at the time of follow-up was 15/35 (42.9%) compared with 8/35 (22.9%) at the time of the initial study (p = 0.063). For men the byssinosis prevalence at follow-up was 16/31 (51.6%) compared with 8/31 (22.9%) at the time of the initial study (p = 0.03). Similarly, the prevalence of almost all other respiratory symptoms was significantly higher at the follow-up than at the time of the initial study. Significant across-shift decrements in FEV1 and FVC were documented at both surveys. The mean annual decline in ventilatory capacity was greater than expected for both female (FVC: -0.036 +/- 0.005 L/yr; FEV1: -0.059 +/- 0.009 L/yr) and male workers (FVC: -0.059 +/- 0.008 L/yr; FEV1: -0.068 +/- 0.006 L/yr) (Mean +/- SE). The mean total airborne dust concentration measured at the time of the follow-up study was 3.95 mg/m3 with an average respirable dust concentration of 0.97 mg/m3. We conclude that continued exposure to high dust concentrations in the cotton textile industry is associated with an increasing prevalence of respiratory symptoms and progressive impairment of lung function. The increase in respiratory impairment was seen both in smokers and nonsmokers.

Abstract
Fetal renal function was evaluated in 255 normal singleton pregnancies between 22 and 41 weeks of gestation and in 133 complicated pregnancies. Hourly fetal urinary production rate (HFUPR), fetal glomerular filtration rate (GFR), fetal tubular water reabsorption (TWR), and the effect of furosemide on fetal micturition was evaluated by ultrasound and a combination of ultrasound and biochemical tests. In normal pregnancies, the HFUPR increased from 2.2 ml/hr at 22 weeks of gestation to 26.3 ml/hr at 40 weeks of gestation. The fetal GFR was 2.66 ml/min at term, and the percentage of TWR was 78%. In complicated pregnancies, the HFUPR was above normal in 5.7% of the growth-retarded fetuses and below the tenth percentile in 58.6%. The GFR was below normal in 68.2% of the group of complicated pregnancies, but TWR did not significantly differ from that in the normal pregnancies. The effect of furosemide was the same in both growth-retarded and normal fetuses. In diabetic pregnancies, HFUPR values varied considerably and correlated with the fetal size. The HFUPR was normal in anencephalic fetuses and in 90.0% of the pregnancies with hydramnios.
