Patients suffering acute coronary syndrome have a very high risk for a repeated syndrome. After stabilization of acute coronary syndrome and discharge of a patient it is important to educate the patient how to prevent it in the future (dietary and life style changes), but treatment of all cardiovascular risk factors/diseases, as hypertension, dyslipidemia, diabetes but stabilization of all cardiovascular diseases is also important. Important is also antithrombotic treatment (mostly double antiplatelet treatment when percutaneous coronary intervention was used with a coronary stents), RAAS blockers, betablockers and statins (strong as atorvastatin and rosuvastatin in the highest possible dose). There are also new risk factors, and vascular inflammation belongs here. We have nowadays also some successful clinical studies how to block inflammation and how to use this treatment. A good secondary cardiovascular prevention is able to improve enourmously prognosis of these patients.

This article examines the presence of the empirical tendency known as the Menzerath-Altmann Law (MAL) on protein secondary structures. MAL is related to optimization principles observed in natural languages and in genetic information on chromosomes or protein domains. The presence of MAL is examined on a non-redundant dataset of 4728 proteins by verifying significant, negative correlations and testing classical and newly proposed formulas by fitting the observed trend. We conclude that the lengths of secondary structures are specifically dependent on their number inside the protein sequence, while possibly reflecting the formula proposed in this paper. This behavior is observed on average but is individually avoidable and possibly driven by a latent cost function. The data suggest that MAL could provide a useful guiding principle in protein design.

A number of studies have been conducted with the onset of secondary progressive multiple sclerosis as an inclusion criterion or an outcome of interest. However, a standardized objective definition of secondary progressive multiple sclerosis has been lacking. The aim of this work was to evaluate the accuracy and feasibility of an objective definition for secondary progressive multiple sclerosis, to enable comparability of future research studies. Using MSBase, a large, prospectively acquired, global cohort study, we analysed the accuracy of 576 data-derived onset definitions for secondary progressive multiple sclerosis and first compared these to a consensus opinion of three neurologists. All definitions were then evaluated against 5-year disease outcomes post-assignment of secondary progressive multiple sclerosis: sustained disability, subsequent sustained progression, positive disability trajectory, and accumulation of severe disability. The five best performing definitions were further investigated for their timeliness and overall disability burden. A total of 17 356 patients were analysed. The best definition included a 3-strata progression magnitude in the absence of a relapse, confirmed after 3 months within the leading Functional System and required an Expanded Disability Status Scale step ≥4 and pyramidal score ≥2. It reached an accuracy of 87% compared to the consensus diagnosis. Seventy-eight per cent of the identified patients showed a positive disability trajectory and 70% reached significant disability after 5 years. The time until half of all patients were diagnosed was 32.6 years (95% confidence interval 32-33.6) after disease onset compared with the physicians' diagnosis at 36 (35-39) years. The identified patients experienced a greater disease burden [median annualized area under the disability-time curve 4.7 (quartiles 3.6, 6.0)] versus non-progressive patients [1.8 (1.2, 1.9)]. This objective definition of secondary progressive multiple sclerosis based on the Expanded Disability Status Scale and information about preceding relapses provides a tool for a reproducible, accurate and timely diagnosis that requires a very short confirmation period. If applied broadly, the definition has the potential to strengthen the design and improve comparability of clinical trials and observational studies in secondary progressive multiple sclerosis.

SUMMARY: Every protein family has a set of characteristic secondary structures. However, due to individual variations, a single structure is not enough to represent the whole family. OverProt can create a secondary structure consensus, showing the general fold of the family as well as its variation. Our server provides precomputed results for all CATH superfamilies and user-defined computations, visualized by an interactive viewer, which shows the secondary structure element type, length, frequency of occurrence, spatial variability and β-connectivity. AVAILABILITY AND IMPLEMENTATION: OverProt Server is freely available at https://overprot.ncbr.muni.cz. SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

AIMS: Prevention guidelines have identified the management of obese patients as an important priority to reduce the burden of incident and recurrent cardiovascular disease. Still, studies have demonstrated that over 80% of patients with coronary heart disease (CHD) fail to achieve their weight target. Here, we describe advice received and actions reported by overweight CHD patients since being discharged from hospital and how weight changes relate to their risk profile. METHODS AND RESULTS: Based on data from 10 507 CHD patients participating in the EUROASPIRE IV and V studies, we analysed weight changes from hospital admission to the time of a study visit ≥6 and <24 months later. At hospitalization, 34.9% were obese and another 46.0% were overweight. Obesity was more frequent in women and associated with more comorbidities. By the time of the study visit, 19.5% of obese patients had lost ≥5% of weight. However, in 16.4% weight had increased ≥5%. Weight gain in those overweight was associated with physical inactivity, non-adherence to dietary recommendations, smoking cessation, raised blood pressure, dyslipidaemia, dysglycaemia, and lower levels of quality of life. Less than half of obese patients was considering weight loss in the coming month. CONCLUSIONS: The management of obesity remains a challenge in the secondary prevention of CHD despite a beneficial effect of weight loss on risk factor prevalences and quality of life. Cardiac rehabilitation programmes should include weight loss interventions as a specific component and the incremental value of telehealth intervention as well as recently described pharmacological interventions need full consideration.

Naturally occurring secondary amino acids, with proline as the main representative, contain an alpha-imino group in a cycle that is typically four-, five-, and six-membered. The unique ring structure exhibits exceptional properties-conformational rigidity, chemical stability, and specific roles in protein structure and folding. Many proline analogues have been used as valuable compounds for the study of metabolism of both prokaryotic and eukaryotic cells and for the synthesis of compounds with desired biological, pharmaceutical, or industrial properties. The D-forms of secondary amino acids play different roles in living organisms than the L-forms. They have different metabolic pathways, biological, physiological, and pharmacological effects, they can be indicators of changes and also serve as biomarkers of diseases. In the scientific literature, the number of articles examining D-amino acids in biological samples is increasing. The review summarises information on the occurrence and importance of D- and L-secondary amino acids-azetidic acid, proline, hydroxyprolines, pipecolic, nipecotic, hydroxypipecolic acids and related peptides containing these D-AAs, as well as the main analytical methods (mostly chromatographic) used for their enantiomeric determination in different matrices (biological samples, plants, food, water, and soil).

BACKGROUND: Protein function is determined by many factors, namely by its constitution, spatial arrangement, and dynamic behavior. Studying these factors helps the biochemists and biologists to better understand the protein behavior and to design proteins with modified properties. One of the most common approaches to these studies is to compare the protein structure with other molecules and to reveal similarities and differences in their polypeptide chains. RESULTS: We support the comparison process by proposing a new visualization technique that bridges the gap between traditionally used 1D and 3D representations. By introducing the information about mutual positions of protein chains into the 1D sequential representation the users are able to observe the spatial differences between the proteins without any occlusion commonly present in 3D view. Our representation is designed to serve namely for comparison of multiple proteins or a set of time steps of molecular dynamics simulation. CONCLUSIONS: The novel representation is demonstrated on two usage scenarios. The first scenario aims to compare a set of proteins from the family of cytochromes P450 where the position of the secondary structures has a significant impact on the substrate channeling. The second scenario focuses on the protein flexibility when by comparing a set of time steps our representation helps to reveal the most dynamically changing parts of the protein chain.

SUMMARY: Secondary structures provide a deep insight into the protein architecture. They can serve for comparison between individual protein family members. The most straightforward way how to deal with protein secondary structure is its visualization using 2D diagrams. Several software tools for the generation of 2D diagrams were developed. Unfortunately, they create 2D diagrams based on only a single protein. Therefore, 2D diagrams of two proteins from one family markedly differ. For this reason, we developed the 2DProts database, which contains secondary structure 2D diagrams for all domains from the CATH and all proteins from PDB databases. These 2D diagrams are generated based on a whole protein family, and they also consider information about the 3D arrangement of secondary structure elements. Moreover, 2DProts database contains multiple 2D diagrams, which provide an overview of a whole protein family's secondary structures. 2DProts is updated weekly and is integrated into CATH. AVAILABILITY AND IMPLEMENTATION: Freely accessible at https://2dprots.ncbr.muni.cz. The web interface was implemented in JavaScript. The database was implemented in Python. SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

BACKGROUND AND OBJECTIVE: Recommendations for preventing cardiovascular (CV) disease are currently separated into primary and secondary prevention. We hypothesize that relative effects of interventions for CV prevention are not different across primary and secondary prevention cohorts. Our aim was to test for differences in relative effects on CV events in common preventive CV interventions across primary and secondary prevention cohorts. METHODS AND RESULTS: A systematic search was performed to identify individual patient data (IPD) meta-analyses that included both primary and secondary prevention populations. Eligibility assessment, data extraction, and risk of bias assessment were conducted independently and in duplicate. We extracted relative risks (RR) with 95% confidence intervals (95% CI) of the interventions over patient-important outcomes and estimated the ratio of RR for primary and secondary prevention populations. We identified five eligible IPDs representing 524,570 participants. Quality assessment resulted in overall low-to-moderate methodological quality. We found no subgroup effect across prevention categories in any of the outcomes assessed. CONCLUSION: In the absence of significant treatment-subgroup interactions between primary and secondary CV prevention cohorts for common preventive interventions, clinical practice guidelines could offer recommendations tailored to individual estimates of CV risk without regard to membership to primary and secondary prevention cohorts. This would require the development of reliable ASCVD risk estimators that apply across both cohorts.

Secondary uveitic glaucoma is a serious sight-threatening complication of intraocular inflammation (uveitis). It develops in approximately 10-20% of patients with uveitis (although this figure may be higher depending on the type of inflammation). It is more commonly associated with chronic forms of uveitis, especially anterior uveitis. Elevation of intraocular pressure (IOP) and the development of secondary glaucoma arise as a direct or indirect consequence of uveitis, and may develop further in association with therapy for intraocular inflammation. Several types of uveitic glaucoma are distinguished according to the mechanism of development: open-angle secondary glaucoma (including steroid-induced secondary glaucoma), angle-closure secondary glaucoma, and a combination of both. It is necessary to determine the pathogenesis of uveitis and target the treatment of the inflammatory process according to it. Subsequently, it is necessary to determine the type of secondary glaucoma, which influences the choice of therapy. Compensation for IOP should be achieved as quickly as possible, before irreversible damage to the optic nerve and visual field occurs. In the first instance, we choose conservative pharmacological therapy. However, this therapy fails more often in secondary uveitic glaucoma than in primary open-angle glaucoma. For this reason, surgical or laser therapy is necessary for refractory glaucoma. Trabeculectomy remains the gold standard in surgical therapy for secondary uveitic glaucoma, but other surgical techniques can also be used (Ahmed drainage implants, goniotomy in the paediatric population, surgical iridectomy, and synechiae for angle closure etc.). The choice of method is individualised according to the clinical findings of the patient and previous ocular procedures. However, the main factor influencing the success and efficacy of filtration surgery is adequate therapy and control of the intraocular inflammatory process.
