if oncologic benefit clearly outweighs cardiovascular harm.Colloidal nanoplatelets (NPLs) are promising materials for lasing applications. The properties are usually discussed in the framework of 2D materials, where strong excitonic effects dominate the optical properties near the band edge. At the same time, NPLs have finite lateral dimensions such that NPLs are not true extended 2D structures. Here we study the photophysics and gain properties of CdSe/CdS/ZnS core-shell-shell NPLs upon electrochemical n doping and optical excitation. Steady-state absorption and PL spectroscopy show that excitonic effects are weaker in core-shell-shell nanoplatelets due to the decreased exciton binding energy. Transient absorption studies reveal a gain threshold of only one excitation per nanoplatelet. Using electrochemical n doping, we observe the complete bleaching of the band edge exciton transitions. Combining electrochemical doping with transient absorption spectroscopy, we demonstrate that the gain threshold is fully removed over a broad spectral range and gain coefficients of several thousand cm-1 are obtained. These doped NPLs are the best performing colloidal nanomaterial gain medium reported to date, with the lowest gain threshold and broadest gain spectrum and gain coefficients that are 4 times higher than in n-doped colloidal quantum dots. The low exciton binding energy due to the CdS and ZnS shells, in combination with the relatively small lateral size of the NPLs, results in excited states that are effectively delocalized over the entire platelet. Core-shell NPLs are thus on the border between strong confinement in QDs and dominant Coulombic effects in 2D materials. We demonstrate that this limit is in effect ideal for optical gain and that it results in an optimal lateral size of the platelets where the gain threshold per nm2 is minimal.Chronic pain in the head and face region has a predicted prevalence of 20% in Europe, and is more common in women than men. The etiology of temporomandibular disorder (TMD) is multifactorial, and high levels of psychological stress amplify its symptoms. We were interested in how headache reported in RDC/TMD is associated with stress. Individuals with an average age of 18 years were included in the study. They were all volunteer participants in a research project. Clinical evaluation of each subject was performed using the RDC/TMD dual-axis diagnostic system. All participants filled out the PSS-10 questionnaire. A total of 138 individuals participated in the study, of which 107 were female. Headache was reported by 83 participants (59.4%), with females presenting higher scores on the PSS-10; this was statistically significant. A comparison between PSS-10 questionnaire results and headache level shows insignificant differences. However, the higher the stress level in the participant, the higher the headache score. Females are more susceptible to perceived stress, which can have an effect on TMD.Pain in the masticatory muscles or temporomandibular joints may in some cases be a symptom of other afflictions occurring in this region. The aim of the study was to present the differential diagnosis of temporomandibular disorders (TMD) and other diseases in the craniofacial area, based on review of the literature. Using the key words "differential diagnosis of TMD", "pain of non-dental origin" and "chronic orofacial pain", PUBMED and Scopus databases were systematically searched for articles in English from 2005 to 2020. Additionally, the PUBMED database was supplementarily reviewed using the keywords "Lyme disease orofacial symptoms" for the English-language articles published in the years 1996-2020. Out of 445 publications from PUBMED and Scopus databases as well as other sources, 57 articles describing the pathogenesis and characteristic symptoms of diseases that may cause pain similar to that occurring in TMD as well as diagnostic methods used in differential diagnosis of TMD were selected for analysis. Dental and jawbones-related conditions, ear and maxillary sinus diseases, as well as ailments of neuropathic and vascular origin, were taken into account. Neoplastic processes taking place in this region and less often occurring diseases caused by viruses, bacteria and parasites were also described. Conclusions. Correct diagnosis of temporomandibular disorders is based on medical history and thorough physical examination, as well as results of additional tests. Pain localized in the head and neck structures may have diverse, sometimes complex aetiology, and may require multidisciplinary treatment. Observation of the patient's behaviour and - in selected cases - the results of additional laboratory tests, also play a significant role.Arterial stiffness is a characteristic of the arterial wall strongly associated with ageing and hypertension. It has been confirmed as a significant cardio-vascular risk factor. Despite available non- invasive measurement methods of central artery stiffening, it has not become a prevalent diagnostic marker in primary care so far. This article provides an overview of pathophysiology of arterial stiffness, possible diagnostic techniques, association with cardiovascular conditions and potential perspective of primary care to implement an additional distinctive parameter to evaluate cardiac risk.Tenosynovial Giant Cell Tumor (TGCT) is a group of typically benign lesions arising from the synovium of joints, bursae and tendon sheaths. Depending on their growth pattern and clinical course, they are divided into localized and diffuse types. It is predominantly caused by a mutation in the stromal cells of the synovial membrane leading to overexpression of the colony stimulating factor 1 that recruits CSF1R-expressing cells of the mononuclear phagocyte lineage into the tumor mass. The lesions contain mainly histiocyte-like and synovial cells accompanied by varying numbers of multinucleated giant cells, mononuclear cells, foam cells, inflammatory cells and hemosiderin deposits. The gold standard for detect- ing and monitoring the disease is MRI, where the characteristic hemosiderin accumulation can be best appreciated, but it is a histological examination that is most conclusive. The main treatment is surgical resection of all pathological tissue, but radio- and chemotherapy are also viable options for certain groups of patients.I n t r o d u c t i o n The COVID-19 pandemic has put healthcare systems worldwide under huge strain, resulting in a significant loss of their capacity and availability. Patients have become more reluctant to contact their doctors or call an ambulance in case of myocardial infarction (MI) symptoms onset. It has been accompanied by a significant decrease in the number of coronary angiography and PCI procedures performed. O b j e c t i v e s The aim of the study is to evaluate the role of online health information in the patient- dependent phase of MI management during the COVID-19 lockdown in Europe. Methods We analyzed Google Trends data on the popularity of phrases related to MI symptoms, respiratory tract infection, urological complaints, and terms unrelated to health, for the period of the first COVID-19 lockdown, along with the data from the corresponding weeks from 2017-2019 in seven European countries. R e s u l t s The search volume for particular symptoms of myocardial infarction increased in all studied countries, compared to the analogous period from 2017-2019, with a significant increase in for chest pain, shortness of breath, fear, and palpitations in most countries. These changes have not been accompanied by increased interest in terms related to respiratory tract infection symptoms and urological complaints. C o n c l u s i o n s Our findings suggest that during lockdown, patients with MI symptoms may have tried to manage their complaints on their own, using information from the Internet. This demonstrates the growing role of the Internet in the patient's decision-making process in the emergency situation, indicating a growing need for reliable and freely available online information provided by healthcare professionals.There is a discrepancy between the research exploring e-learning at medical universities in Central/Eastern and Western European countries. The aim of the MeSPeLA study was to explore the understanding, experience and expectations of Polish medical students in terms of e-learning. Questionnaire containing open-ended and closed questions supplemented by focus group discussion was validated and performed among 204 medical students in Poland before COVID-19 pandemia. Several domains understanding of e-learning definitions; students' experience, preferences, expectations and perceptions of e-learning usefulness, advantages and disadvantages were addressed. The qualitative data were analyzed using an inductive approach. 46.0% of students chose a communication-oriented definition as the most appropriate. 7.4% claimed not to have any experience with e-learning. 76.8% of respondents indicated they had contact with e-learning. The main reported e-learning advantages were time saving and easier time management. The most common drawback was limited social interactions. The acceptance of the usage of e-learning was high. Medical undergraduates in Poland regardless of the year of studies, gender or choice of future specialization showed positive attitudes towards e-learning. Students with advanced IT skills showed a better understanding of the e-learning definition and perceived e-learning to be a more useful approach. The expectations and perceptions about e-learning in Polish medical schools seems similar to some extent to that in Western European and the United States so we can be more confident about applying some lessons from these research to Poland or other post-communist countries. Such application has been accelerated due to COVID-19 pandemia.
The aim of the study was to assess the relationship between body composition, nutritional status and physical ability in elderly outpatients.

. In this cross-sectional study, demographic data and medical history were collected from patients aged ≥60 years followed in the Geriatric Outpatient Clinic from October 2010 to February 2014. Body composition was examined using a dual-energy X-ray absorptiometry. Physical performance was assessed by gait speed (GS), Timed Up&Go Test (TUG), Six Minute Walk Test (6MWT). The nutritional status was evaluated using the Mini Nutritional Assessment (MNA) and serum albumin level.

Mean age (± SD) of 76 patients (64.47% men) was 71.93 ± 8.88 yrs. The most common diseases were hypertension (89.47%), coronary heart disease (81.58%) and chronic heart failure (68.4%). In multiple regression analyses, the factors significantly affecting GS were age (B = - 0.017, p ≤0.0001), good nutritional status (B = 0.038, p <0.01) and percent of lower extremity fat (B = - 0.009, p & body composition was found determining the deterioration of all assessed parameters of physical fitness. Identifying the relationship between body composition, nutritional status and physical performance can help elucidate the causes of disability and target preventive measures.5-fluorouracil (5-FU), which is a commonly used chemotherapy agent exerts undesired cardiac toxicity. AOA hemihydrochloride Mitochondrial dysfunction is thought to be one of potentially important mechanisms of 5-FU- induced cardiotoxicity. α-ketoglutarate dehydrogenase (α-KGDHC) is the key regulatory enzyme of TCA cycle. The complex consists of multiple copies of three catalytic subunits α-ketoglutarate dehydrogenase (E1), dihydrolipoamide succinyltransferase (E2) and dihydrolipoamide dehydrogenase (E3). α-KGDHC together with branched chain α-ketoacid dehydrogenase (BCKDH) and pyruvate dehydrogenase (PDH), are the members of 2-oxoacid dehydrogenases family that share some structural and functional similarities. Recently, it has been found that 5-FU stimulates BCKDH in rat's cardiac muscle. Therefore, we hypothesize that 5-FU modifies α-KGDHC activity and affects cardiac muscle metabolism. The aim of this study was to determine the effect of 5-FU on α-KGDHC activity and protein levels of E1 and E2 subunits of the complex in rat's cardiac muscle.
