Научно-технический прогресс или безопасность человечества

Постепенное развитие общественного производства, его постоянное совершенствование являются фундаментальными закономерностями экономической жизни человечества. Они основываются на прогрессе науки и техники. Научно-технический прогресс за тысячелетия человеческой цивилизации прошел сложный и противоречивый путь развития. Это было вызвано тем, что именно технический прогресс, который осуществлялся на первых этапах развития общества, осуществлялся отдельно от научного прогресса до конца XVIII - начала XIX в. И только в период промышленной революции началось быстрое сближение научного и технического прогресса и возник целостный научно-технический прогресс.Gradual development of social production, its constant improvement of the fundamental laws of the economic life of mankind. They are based on the progress of science and technology. Scientific and technological progress for the millennium of human civilization has passed a complex and contradictory path of development. This was due to the fact that it was the technical progress that was carried out at the first stages of the development of society that was carried out separately from scientific progress until the end of the eighteenth and early nineteenth centuries. And only in the period of the industrial revolution did the rapid rapprochement of scientific and technological progress and the emergence of integral scientific and technological progress began

Associations between illness cognitions and health-related quality of life in the first year after diagnosis of amyotrophic lateral sclerosis

Objective: To describe illness cognitions among patients with amyotrophic lateral sclerosis (ALS), to study crosssectional associations between illness cognitions and health-related quality of life (HRQoL) and to study the predictive value of illness cognitions measured shortly after the diagnosis for HRQoL at follow-up. Methods: Prospective longitudinal design. We administered Self-report questionnaires at study onset (n = 72) and follow-up (n = 48). Median follow-up period was 10.0 months. At baseline median ALS Functional Rating Scale-Revised was 43, median time since onset of symptoms was 13.6 months, 79% of patients presented with spinal onset. Illness cognitions Helplessness, Acceptance and Disease Benefits were measured with the Illness Cognitions Questionnaire (ICQ) and HRQoL with the ALS Assessment Questionnaire (ALSAQ-40). Correlational and regression analyses were used. Results: Patients experienced more Helplessness at follow-up. We found no significant changes in Acceptance or Disease Benefits at follow-up. In cross-sectional analyses, Helplessness was independently related to worse HRQoL at baseline (beta = 0.44; p =.001) and Acceptance and Disease Benefits were independently related to worse HRQoL at follow-up (beta = -0.17, p =.045) and (beta = -0.186, p =.03 respectively). Longitudinal analyses showed that, adjusted for disease severity at baseline, Helplessness at baseline was a predictor of worse HRQoL at follow-up (beta = 0.43; p =.006). None of the illness cognitions were a significant predictor of HRQoL with adjustment for baseline HRQoL. Conclusion: Helplessness was independently associated with HRQoL in the cross-sectional and longitudinal analyses. These results can help us identify patients shortly after diagnosis who might benefit from psychological interventions

Size of third and fourth ventricle in obstructive and communicating acute hydrocephalus after aneurysmal subarachnoid hemorrhage

In patients with acute hydrocephalus after aneurysmal subarachnoid haemorrhage (SAH), lumbar drainage is possible if the obstruction is in the subarachnoid space (communicating hydrocephalus). In case of intraventricular obstruction (obstructive hydrocephalus), ventricular drainage is the only option. A small fourth ventricle is often considered a sign of obstructive hydrocephalus. We investigated whether the absolute or relative size of the fourth ventricle can indeed distinguish between these two types of hydrocephalus. On CT-scans of 76 consecutive patients with acute headache but normal CT and CSF, we measured the cross-sectional surface of the third and fourth ventricle to obtain normal planimetric values. Subsequently we performed the same measurements on 117 consecutive SAH patients with acute hydrocephalus. These patients were divided according to the distribution of blood on CT-scan into three groups: mainly intraventricular blood (n = 15), mainly subarachnoid blood (n = 54) and both intraventricular and subarachnoid blood (n = 48). The size of the fourth ventricle exceeded the upper limit of normal in 2 of the 6 (33%) patients with intraventricular blood but without haematocephalus, and in 15 of the 54 (28%) patients with mainly subarachnoid blood. The mean ratio between the third and fourth ventricle was 1.45 (SD 0.66) in patients with intraventricular blood and 1.42 (SD 0.91) in those with mainly subarachnoid blood. Neither fourth ventricular size nor the ratio between the third and fourth ventricles discriminates between the two groups. A small fourth ventricle does not necessarily accompany obstructive hydrocephalus and is therefore not a contraindication for lumbar drainage

Short-term surgical complications after radical hysterectomy—A nationwide cohort study

Introduction: Centralization has, among other aspects, been argued to have an impact on quality of care in terms of surgical morbidity. Next, monitoring quality of care is essential in identifying areas of improvement. This nationwide cohort study was conducted to determine the rate of short-term surgical complications and to evaluate its possible predictors in women with early-stage cervical cancer. Material and methods: Women diagnosed with early-stage cervical cancer, 2009 FIGO stages IB1 and IIA1, between 2015 and 2017 who underwent radical hysterectomy with pelvic lymphadenectomy in 1 of the 9 specialized medical centers in the Netherlands, were identified from the Netherlands Cancer Registry. Women were excluded if primary treatment consisted of hysterectomy without parametrial dissection or radical trachelectomy. Women in whom radical hysterectomy was aborted during the procedure, were also
