As a whole, the data suggest that, due to their motor nature, finger numerical configurations are not processed as simple visual stimuli but in relation to corporal and cultural counting habits, in agreement with the embodied framework of numerical cognition.

Data on the factors that influence mortality after surgery in South Africa are scarce, and neither these data nor data on risk-adjusted in-hospital mortality after surgery are routinely collected. Biricodar Predictors related to the context or setting of surgical care delivery may also provide insight into variation in practice. Variation must be addressed when planning for improvement of risk-adjusted outcomes. Our objective was to identify the factors predicting in-hospital mortality after surgery in South Africa from available data.

A multivariable logistic regression model was developed to identify predictors of 30-day in-hospital mortality in surgical patients in South Africa. Data from the South African contribution to the African Surgical Outcomes Study were used and included 3800 cases from 51 hospitals. A forward stepwise regression technique was then employed to select for possible predictors prior to model specification. Model performance was evaluated by assessing calibration and discrimination. The Souw the context of care influences post-operative mortality in South Africa. It does, however, provide a basis for reporting risk-adjusted perioperative mortality rate in the future, and identifies the types of surgery to be prioritised in quality improvement projects at a local or national level.

Multidrug-resistant gram-negative bacteria (MDRGN) pose an emerging threat in German hospitals and in the outpatient sector. However, only few studies have investigated the prevalence of MDRGN in nonhospital settings and the associated risk factors for colonization.

In our study we determined the prevalence of MDRGN in inhabitants of long-term care facilities (LTCFs) and associated risk factors for colonization in the region Weimar, Weimarer Land, and Jena.

Between May and August 2019, deep rectal swabs were taken from 307 inhabitants of 13facilities and examined microbiologically for the presence of MDRGN. Furthermore, using astandardized questionnaire, the characteristics of the inhabitants were collected and their association with the likelihood for colonization with MDRGN was analyzed.

MDRGN were found in 59swabs, predominantly Escherichia coli (95%). The weighted prevalence of extended spectrum beta-lactamase-producing bacteria was 19.1% and for MDRGN with additional resistances to fluoroquinolones was 12.3%. Resistances to carbapenems or carbapenemases were not found. Multivariable as well as univariable analysis recognized the presence of chronic wounds to be apotential risk factor (OR 2,66 [95 %-CI 1,54-4,60]). Additionally, the univariable analysis detected the necessity of awheelchair and the accommodation in double rooms as risk factors.

The prevalence of MDRGN found in our study is similar to findings of previous German studies. The result shows the importance of strict compliance with basic hygiene guidelines for all inhabitants of LTCFs for the prevention of transmission of MDRGN.

The coronavirus pandemic is affecting global health systems, endangering daily patient care. Hemato-oncological patients are particularly vulnerable to infection, requiring decisive recommendations on treatment and triage. The aim of this survey amongst experts on radiation therapy (RT) for lymphoma and leukemia is to delineate typical clinical scenarios and to provide counsel for high-quality care.

Amulti-item questionnaire containing multiple-choice and free-text questions was developed in apeer-reviewed process and sent to members of the radiation oncology panels of the German Hodgkin Study Group and the German Lymphoma Alliance. Answers were assessed online and analyzed centrally.

Omission of RT was only considered in aminority of cases if alternative treatment options were available. Hypofractionated regimens and reduced dosages may be used for indolent lymphoma and fractures due to multiple myeloma. Overall, there was atendency to shorten RT rather than to postpone or omit it. Even in case of critical resource shortage, panelists agreed to start emergency RT for typical indications (intracranial pressure, spinal compression, superior vena cava syndrome) within 24 h. Possible criteria to consider for patient triage are the availability of (systemic) options, the underlying disease dynamic, and the treatment rationale (curative/palliative).

RT for hemato-oncological patients receives high-priority and should be maintained even in later stages of the pandemic. Hypofractionation and shortened treatment schedules are feasible options for well-defined constellations, but have to be discussed in the clinical context.

In the present study, the expression level of microRNA(miR)‑487b‑3p in OS specimens and cell lines was found to be decreased, and the expression level of miR‑487b‑3p was associated with overall survival in patients with OS. The inhibition of miR‑487b‑3p stimulated OS cell migration and contributed to the development of chemoresistance. In contrast, the overexpression of miR‑487b‑3p significantly inhibited OS cell migration and enhanced the sensitivity of OS cells to doxorubicin treatment. In addition, the results from the present study revealed that the suppression of miR‑487b‑3p stimulates OS stemness, while the overexpression of miR‑487b‑3p suppresses OS stemness. Notably, in vivo experiments also revealed that the overexpression of miR‑487b‑3p inhibited cancer stem cell (CSC)‑induced tumor formation, and the combination treatment of miR‑487b‑3p and doxorubicin significantly inhibited CSC‑induced tumor growth. Furthermore, miR‑487b‑3p exerts its anticancer role by targeting aldehyde dehydrogenase 1 family member A3 in OS. Taken together, the results from the present study suggests that miR‑487b‑3p is a tumor suppressor and that the overexpression of miR‑487b‑3p is a novel strategy to inhibit tumor metastasis and chemoresistance in OS.Curcumin has been used since ancient times as a treatment for a wide range of pathologies. For centuries, it has been considered to be an effective aid for common human diseases. Curcuma longa has been reported to possess various beneficial properties and actions, including anti‑inflammatory, proapoptotic, antiangiogenic and cortisone‑like actions. Pterygium is a degenerative disorder of the conjunctiva indicative of a strong inflammatory condition that requires surgical treatment, which often results in disfiguring sclerocorneal scars. The delay in the healing of superficial corneal wounds caused by topical administration of light‑cortisone results in improved restoration of corneal functions and anatomy compared with physiological healing processes. The present review is focused on the medicinal properties of curcumin, the main component of Curcuma longa extract, in particular its strong cortisone‑like effect, and its potential use for the prevention and treatment of sclerocorneal scars resulting from pterygium surgical excision.Cognitive deficit is one of the most serious complications of cranial radiotherapy of head and neck cancers. However, the underlying mechanism of this cognitive impairment remains unclear. In the present study, the role of tropomyosin receptor kinase A (TrkA) and its ligand neurotrophin nerve growth factor (NGF) were investigated following whole‑brain irradiation (WBI). Young male Sprague‑Dawley rats underwent WBI at a single dose of 10 Gy. WBI was determined to result in notable memory decline and substantial neurogenesis impairment in the hippocampus 3 months post‑irradiation. Compared with the control group, TrkA protein expression was greater in irradiated rats 1 week after WBI, which then decreased significantly by the 3‑month time‑point. However, no difference in NGF expression was observed from 1 day to 3 months post‑WBI. Overexpression of hippocampal TrkA in rats using adeno‑associated virus ameliorated memory decline induced by irradiation. Additionally, upregulating TrkA expression rescued irradiation‑induced hippocampal precursor cell proliferation and promoted neurogenesis. PI3K, Akt and ERK1/2 phosphorylation were also revealed to be significantly inhibited by WBI, which was ameliorated by TrkA overexpression. Findings of the present study indicated that the TrkA‑dependent signaling pathway may serve a critical role in radiotherapy‑induced cognitive deficit and impairments in neurogenesis.Classical aerosol physics predicts that it is impossible to observe noticeable values of the unattached fraction of decay products of thoron at typical concentrations of aerosol particles. The experimental data have shown that the unattached fraction of the thoron decay products in a monazite storage facility is in the range 0.3-0.6. This effect is caused by local increase in air exchange near the inlet of the sampling device at high 220Rn concentrations. It was found that a dynamic shift between the unattached and attached thoron decay products is also observed in the worker's breathing zone at a high concentration of thoron. The 212Pb unattached fraction in worker's breathing zone was ~0.4. It demonstrates that when evaluating inhalation exposure to the products of the decay of thoron, it is necessary to take into account the increase of the 212Pb unattached fraction in the worker's breathing zone.The estimation of the indoor radon exposure of the population of a country is generally carried out by the means of surveys designed in order to have sample representativeness as a target (population-based survey). However, the estimates of radon concentration distributions could be affected by biases if sampling was not random or in case of differences between sample and target population characteristics. In this work, we performed a preliminary check of the representativeness of the sample used for the second Italian national survey aimed to evaluate radon concentration distribution in each Province. We found that sampled dwellings are mostly located in the main administrative centres, where average radon concentration is generally lower, as compared with the other towns of the Province. The potential source of bias identified in this work suggests to carefully control the occurrence of a sampling imbalance between 'main' cities and other cities of Province and to take it into account in data analysis.

The coronavirus disease 2019 (COVID-19) pandemic has placed unprecedented stress on health systems across the world, and reliable estimates of risk for adverse hospital outcomes are needed.
