Knowledge of medical law amongst doctors of internal diseases

Objectives: In Poland, 95% of medical personnel had not received legal education before they completed their studies. Having been given these facts, we have started questioning legal awareness of people providing medical services. Aim of the study: The study aimed at evaluating the knowledge of allergists and pulmonologists. Material and Methods: The group consisting of 328 allergists and/or pulmonologist completed the questionnaire. Results: The participants possess the best knowledge in providing information to patients about their health status (CV1). Sixty nine % of responders replied correctly, and the difference was significant (p < 0.001) in comparison with next aspect referring to the principles of providing medical services following guidelines created by think-tanks and also possibilities to take autonomous decisions by physicians (CV2). The correct answers in relation to CV2 were given by 57% of responders. The third compared aspect was physicians' awareness of patients' right to giving a consent or refusal before undertaking the medical procedure CV3. Only 55% of physicians gave correct answers and the difference was significant compared to CV1 (p < 0.001) as well as CV2 (p < 0.05). Younger doctors showed to have better knowledge than their older colleagues (p < 0.05). Working in urban workplaces proved to be more associated with better knowledge than in rural ones (p < 0.05). Discussion: Insufficient knowledge results in a low quality of provided services and puts the doctors at risk of being liable. The rates indicate that doctors are not aware of the fact that only legal regulations are binding, while standards not published by the Minister of Health are not legally valid. Half of the respondents have the wrong belief that the opinions expressed by experts make the doctor feel exempt from liability. Probably there are specialities, like occupational medicine which are specially linked with awareness of valid legal rules

Čebyšëv subspaces of JBW ∗ -triples

We describe the one-dimensional Čebyšëv subspaces of a JBW ∗ -triple M by showing that for a non-zero element x in M, Cx is a Čebyšëv subspace of M if and only if x is a Brown-Pedersen quasi-invertible element in M. We study the Čebyšëv JBW ∗ -subtriples of a JBW ∗ -triple M. We prove that for each non-zero Čebyšëv JBW ∗ -subtriple N of M, exactly one of the following statements holds: (a) N is a rank-one JBW ∗ -triple with dim(N)≥2 (i.e., a complex Hilbert space regarded as a type 1 Cartan factor). Moreover, N may be a closed subspace of arbitrary dimension and M may have arbitrary rank; (b) N=Ce, where e is a complete tripotent in M; (c) N and M have rank two, but N may have arbitrary dimension ≥2; (d) N has rank greater than or equal to three, and N=M. We also provide new examples of Čebyšëv subspaces of classic Banach spaces in connection with ternary rings of operators.The authors extend their appreciation to the Deanship of Scientific Research at King Saud University for funding this work through research group No. RG-1435-020.

Moderate Traumatic Brain Injury: The Grey Zone of Neurotrauma

Moderate traumatic brain injury (MTBI) is poorly defined in the literature and the nomenclature “moderate” is misleading, because up to 15 % of such patients may die. MTBI is a heterogeneous entity that shares many aspects of its pathophysiology and management with severe traumatic brain injury. Many patients who ‘’talk and died’’ are MTBI. The role of neuroimaging is essential for the proper management of these patients. To analyze all aspects of the pathophysiology and management of MTBI, proposing a new way to categorize it considering the clinical picture and neuroimaging findings. We proposed a different approach to the group of patients with Glasgow Coma Scale (GCS) ranging from 9 through 13 and we discuss the rationale for this proposal. Patients with lower GCS scores (9–10), especially those with significant space-occupying lesions on the CT scan, should be managed following the guidelines for severe traumatic brain injury, with ICU observation, frequent serial computed tomography (CT) scanning and ICP monitoring. On the other hand, those with higher range GCS (11–13) can be managed more conservatively with serial neurological examination and CT scans. Given the available evidence, MTBI is an entity that needs reclassification. Large-scale and well-designed studies are urgently needed

Current challenges and implications for dengue, chikungunya and Zika seroprevalence studies worldwide: A scoping review.

BACKGROUND:Arboviral infections are a public health concern and an escalating problem worldwide. Estimating the burden of these diseases represents a major challenge that is complicated by the large number of unapparent infections, especially those of dengue fever. Serological surveys are thus required to identify the distribution of these diseases and measure their impact. Therefore, we undertook a scoping review of the literature to describe and summarize epidemiological practices, findings and insights related to seroprevalence studies of dengue, chikungunya and Zika virus, which have rapidly expanded across the globe in recent years. METHODOLOGY/PRINCIPAL FINDINGS:Relevant studies were retrieved through a literature search of MEDLINE, WHOLIS, Lilacs, SciELO and Scopus (2000 to 2018). In total, 1389 publications were identified. Studies addressing the seroprevalence of dengue, chikungunya and/or Zika written in English or French and meeting the inclusion and exclusion criteria were included. In total, 147 studies were included, from which 185 data points were retrieved, as some studies used several different samples. Most of the studies were exclusively conducted on dengue (66.5%), but 16% were exclusively conducted on chikungunya, and 7 were exclusively conducted on Zika; the remainder were conducted on multiple arboviruses. A wide range of designs were applied, but most studies were conducted in the general population (39%) and in households (41%). Although several assays were used, enzyme-linked immunosorbent assays (ELISAs) were the predominant test used (77%). The temporal distribution of chikungunya studies followed the virus during its rapid expansion since 2004. The results revealed heterogeneity of arboviruses seroprevalence between continents and within a given country for dengue, chikungunya and Zika viruses, ranging from 0 to 100%, 76% and 73% respectively. CONCLUSIONS/SIGNIFICANCE:Serological surveys provide the most direct measurement for defining the immunity landscape for infectious diseases, but the methodology remains difficult to implement. Overall, dengue, chikungunya and Zika serosurveys followed the expansion of these arboviruses, but there remain gaps in their geographic distribution. This review addresses the challenges for researchers regarding study design biases. Moreover, the development of reliable, rapid and affordable diagnosis tools represents a significant issue concerning the ability of seroprevalence surveys to differentiate infections when multiple viruses co-circulate
