Influence of health factors on school failure

Uspješnost učenika u usvajanju znanja i vještina tijekom školovanja, vrednovanu rezultatima i postignućem na ispitima prema unaprijed određenim kriterijima, nazivamo školskim uspjehom. Školski neuspjeh se očituje kao trajan neuspjeh u svim ili nekim predmetima, ponavljanju razreda, prekidu školovanja, ali i učenikovom osjećaju neuspjeha. Cilj ovoga preglednog rada je prikaz zdravstvenih čimbenika školskog neuspjeha. Izvršeno je pretraživanje literature u bibliografskim bazama PubMed i Hrčak, u razdoblju od 2008. do 2018. godine, korištenjem ključnih riječi na hrvatskom: školska djeca, školski uspjeh, školski neuspjeh, čimbenici školskog neuspjeha i engleskom jeziku: school performance, school attainment, school-aged children, obesity, sleep, school success, physical activity. Rezultati do sada provedenih istraživanja pokazali su povezanost nezdravih životnih navika, kao što su nedovoljno sna, neredovita i nekvalitetna prehrana, sedentarni način života te pretilost i pothranjenost, s lošijim školskim uspjehom. Navike zdravog stila života, kao što su pravilan raspored obroka, unos zdravih namirnica, rijetka konzumacija zaslađenih pića i brze hrane te redovita tjelesna aktivnost, bili su povezani s boljim obrazovnim ishodima. Razumijevanje povezanosti zdravstvenih čimbenika i školskog uspjeha doprinijet će podizanju svijesti znanstvene i stručne javnosti o važnosti razvoja i očuvanja zdravih životnih navika tijekom školovanja, kako bi se ostvarili akademski potencijali.The success of the student in acquiring knowledge and skills durings schooling, evaluated by results and achievement in exeminations according to predefined criteria, is called school success. School failure occurs as a permanent failure in all or some school subjects, grade retention, drop out of school, as well as children's feelings of failure. The aim of this paper is to show the health factors of school failure. PubMed and Hrčak databases were used for literature research in period from 2008 to 2018, using the keywords in Croatian and English: school performance, school attainment, school-aged children, obesity, sleep, school success, physical activity. The results of the research have shown the connection between unhealthy habits, such as insufficient sleep, irregular and poor quality diet, sedentary lifestyle, obesity and malnutrition, with poorer school success. Healthy habits, such as regular eating, healthy food intake, infrequent consumption of fast-food and sweetened beverage and regular physical activity, were associated with better educational outcomes. Understanding the relationship between health factors and school success will contribute to raising the awareness of the scientific and professional public on the importance of developing and preserving healthy lifestyles during schooling in order to achieve academic potentials

School failure is manifested as a permanent failure in all or some of subjects, repeating the class, ending schooling, but also student\u27s feeling of failure. Among causes of school failure are health factors: sleep, nutrition habits, nutritional status, physical activity and chronic illnesses for which students are absent from school and taking medication and therapy may affect the learning process. Aim: To show relationship between dietary habits, nutritional status and school performance. Methods: Search of literature in bibliographic databases PubMed and Hrčak, from 2008 to 2018, was performed using keywords in Croatian and English. Results: Previous research has shown that nutritional status - undernutrition and obesity, is associated with poorer school success. Healthy eating habits, proper meal schedules, healthy food intake, low consumption of sweetened drinks and fast food, are associated with better educational outcomes. Conclusion: Understanding of relationship between healthy nutrition and nutritional status with school success will contribute to raising the awareness of scientific and professional public about the importance of developing and maintaining healthy living habits and normal body mass during schooling periods in order to achieve academic potential and maintain and enhance health

Incidence and risk factors for venous and arterial thromboses in hospitalized patients with coronavirus disease 2019: data on 4014 patients from a tertiary center registry

Aim To evaluate the burden and predictors of throm - boembolic complications in a large real-life cohort of hos - pitalized patients with established coronavirus disease 2019 (COVID-19). Methods We retrospectively reviewed the records of 4014 consecutive adult patients admitted to a tertiary-level insti - tution because of COVID-19 from March 2020 to March 2021 for the presence of venous and arterial thrombotic events. Results Venous-thromboembolic (VTE) events were pres - ent in 5.3% and arterial thrombotic events in 5.8% patients. The majority of arterial thromboses occurred before or on the day of admission, while the majority of VTE events oc - curred during hospitalization. The majority of both types of events occurred before intensive care unit (ICU) admis - sion, although both types of events were associated with a higher need for ICU use and prolonged immobilization. In multivariate logistic regression, VTE events were inde - pendently associated with metastatic malignancy, known thrombophilia, lower mean corpuscular hemoglobin con - centration, higher D-dimer, lower lactate dehydrogenase, longer duration of disease on admission, bilateral pneu - monia, longer duration of hospitalization, and immobiliza - tion for at least one day. Arterial thromboses were inde - pendently associated with less severe COVID-19, higher Charlson comorbidity index, coronary artery disease, pe - ripheral artery disease, history of cerebrovascular insult, as - pirin use, lower C reactive protein, better functional status on admission, ICU use, immobilization for at least one day, absence of hyperlipoproteinemia, and absence of meta - static malignancy. Conclusion Among hospitalized COVID-19 patients, ve - nous and arterial thromboses differ in timing of presenta - tion, association with COVID-19 severity, and other clinical characteristics

Higher estimated plasma volume status is associated with increased thrombotic risk and impaired survival in patients with primary myelofibrosis

IntroductionBlood plasma represents a large reservoir of cytokines and other mediators of inflammation. Higher estimated plasma volume status (ePVS) has been shown to correlate with increased thrombotic risk in polycythemia vera patients, but its clinical and prognostic associations in patients with myelofibrosis are unknown which we aim to evaluate in this study. Materials and methodsWe retrospectively analysed a multicentric cohort of 238 patients with primary (PMF) and secondary myelofibrosis (SMF). Estimated plasma volume status was calculated using the Strauss-derived Duarte formula. Overall survival (OS) and time to thrombosis (TTT) considering both arterial and venous thromboses were primary endpoints of interest. ResultsMedian ePVS was 5.8 dL/g and it did not significantly differ between PMF and SMF patients. Patients with more advanced disease features, more pronounced inflammation and higher comorbidity burden had higher ePVS. Higher ePVS (> 5.6 dL/g) was associated with shorter OS in PMF (unadjusted hazard ratio, HR = 2.8, 95% confidence interval, CI (1.79-4.41), P 7 dL/g, unadjusted HR = 4.1, 95% CI (1.44-11.59), P = 0.009) patients. Associations with OS diminished in multivariate analyses after adjustments for the dynamic-international-prognostic-scoring-system (DIPSS) and myelofibrosis-secondary-to-PV-and ET-prognostic-model (MYSEC-PM), respectively. Association with TTT remained significant independently of JAK2 mutation, white blood cell count and chronic kidney disease. ConclusionsMyelofibrosis patients with more advanced disease features and more pronounced inflammation have higher ePVS, indicative of expanded plasma volume. Higher ePVS is associated with impaired survival in PMF and SMF and higher thrombotic risk in PMF patients

Evaluation of Absolute Neutrophil, Lymphocyte and Platelet Count and Their Ratios as Predictors of Thrombotic Risk in Patients with Prefibrotic and Overt Myelofibrosis

Aim: To investigate the prognostic contribution of absolute neutrophil (ANC), lymphocyte (ALC), platelet count and their ratios, neutrophil–lymphocyte ratio (NLR) and platelet–lymphocyte ratio (PLR), to thrombotic risk in patients with prefibrotic and overt fibrotic myelofibrosis (MF). Methods: We retrospectively analyzed a cohort of 256 patients with prefibrotic (85 patients) and overt fibrotic MF (171 patients) treated in six Croatian hematological centers. Results: Prefibrotic compared to overt fibrotic MF patients presented with significantly higher ALC, platelet count and PLR, and experienced longer time to thrombosis (TTT). Among prefibrotic patients, ANC > 8.33 × 109/L (HR 13.08, p = 0.036), ALC > 2.58 × 109/L (HR 20.63, p = 0.049) and platelet count > 752 × 109/L (HR 10.5, p = 0.043) remained independently associated with shorter TTT. Among overt fibrotic patients, ANC > 8.8 × 109/L (HR 4.49, p = 0.004), ALC ≤ 1.43 × 109/L (HR 4.15, p = 0.003), platelet count ≤ 385 × 109/L (HR 4.68, p = 0.004) and chronic kidney disease (HR 9.07, p < 0.001) remained independently associated with shorter TTT. Conclusions: Prognostic properties of ANC, ALC and platelet count are mutually independent and exceed those of NLR and PLR regarding thrombotic risk stratification. ALC and platelet count associate in opposite directions with thrombotic risk in prefibrotic and overt fibrotic MF patients
