E Ali, M Raghuvanshi
OBJECTIVE: Open upper limb injuries requiring soft reconstruction can pose a dilemma for trauma surgeons when considering the treatment options. The British Orthopaedic Association and British Association of Plastic, Reconstructive and Aesthetic Surgeons Standard for Trauma (BOAST) have addressed the management of severe open lower limb fractures with the creation of the BOAST 4 guidelines. However, no such gold standard exists for the treatment of open injuries of the upper limb. Furthermore, treatment of these injuries is often more difficult and requires complicated strategies...

Halide perovskites with reduced-dimensionality (e.g. quasi-2D, Q-2D) are promising to be stable while remaining the high performance as compared to their three-dimensional counterpart. Generally, they are obtained in (A1)2(A2)n-1PbnI3n+1 thin films by adjusting A site cations, however, the underlying crystallization kinetics mechanism is less explored. In this manuscript, we employed ternary cations halides perovskite (BA)2(MA,FA)3Pb4I13 Q-2D perovskites as an archetypal model, to understand the principles that links the crystal orientation to the carrier behavior in the polycrystalline film...

The discovery of novel magnetic and electronic properties in low-dimensional materials has led to the pursuit of hierarchical materials with specific substructures. Low-dimensional solids are highly anisotropic by nature and show promise in new quantum materials leading to exotic physical properties not realized in three-dimensional materials. We have the opportunity to extend our synthetic strategy of the flux-growth method to designing single crystalline low-dimensional materials in bulk. The goal of this Account is to highlight the synthesis and physical properties of several low-dimensional intermetallic compounds containing specific structural motifs that are linked to desirable magnetic and electrical properties...

Cardiorespiratory fitness is assessed through graded exercise tests that determine the maximum amount of sustained mechanical work that an individual can perform while also providing health and fitness related information. This manuscript describes a novel method to perform graded exercise tests that uses posteriorly directed resistive forces. The purpose of this investigation is to validate a novel resistance based test in comparison to a traditional speed and incline based test in a cohort of non-impaired individuals...

Therapeutic antibodies (IgG-type) contain several post-translational modifications (PTMs) whereby introducing a large heterogeneity, both structural and functional, into this class of therapeutics. Of these modifications, glycosylation in the fragment crystallizable (Fc) region is the most heterogeneous PTM, which can affect the stability of the molecule and interactions with Fc-receptors in vivo. Hence, the glycoform distribution can affect the mode of action and have implications for bioactivity, safety and efficacy of the drug...

Junhui Miao, Bin Meng, Jun Liu, Lixiang Wang
Organic molecules with wide absorption spectra exhibit great sunlight harvesting capability and are critically important for solar cell applications. In this manuscript, we develop an A-D-A'-D-A type small molecule acceptor (IID-IC) using isoindigo (IID) as the electron-deficient core unit (A'), thiophene as the electron-rich bridging units (D) and 2-(3-oxo-2,3-dihydroinden-1-ylidene)malononitrile (IC) as the electron-deficient endcapping groups (A). IID-IC shows a wide absorption spectrum with the full width at half maximum (FWHM) of 190 nm, which is almost twice that of a typical A-D-A type molecule acceptor...

BACKGROUND: The lower part of the digestive tract includes the large intestine, rectum and anus. Treatment algorithms of cancers in these localities have significant differences in both early and advanced stages. The vast majority of metastatic cases are incurable. A few years ago, it was generally accepted that gastrointestinal tumors are poorly immunogenic and modern immunotherapy would not work in gastrointestinal cancers. The breakthrough has become the recognition of the mismatch repair system (MMR) that affects the microsatellite instability (MSI) and its role in the development of colorectal carcinoma (CRC)...

Treatment of renal cell carcinoma is still palliative. Targeted therapy increases response rates and prolongs overall survival and progression-free survival compared with cytokines and chemotherapy. Checkpoint inhibitors constitute the up-date of therapeutic approaches, and anti-PD-1 antibody, one checkpoint inhibitor, is now well established as a second and/or third palliative treatment for patients with renal cell carcinoma. In this study, we present the latest data from current studies on cytokines, cancer vaccines, ipilimumab, and nivolumab...

Chemotherapy prolongs overall survival (OS) in esophageal (EC) and gastric cancer (GC). Unsatisfactory results of systemic therapy initiated a search for new treatment options. In metastatic disease, a number of targeted drugs were tested; however, several phase III studies assessing receptor tyrosin kinase-related signaling pathways, such as EGFR, MET/HGF or mTOR, failed. Trastuzumab remains the only targeted drug with a known molecular predictor, which extended the OS in metastatic gastric adenocarcinoma and adenocarcinoma of esophago-gastric junction...

B Melichar, M Spisarová
The advent of immunotherapy has changed our concept of how to manage metastatic disease. With the exception of relatively rare tumors, the treatment of metastatic cancer is still considered as palliative, and in systemic treatment immunotherapy is often selected, considering better tolerance. Immunotherapy opens the perspective of a long-term, possibly durable, response, and, in contrast to other approaches to targeted therapy, is active across a spectrum of tumors. Combined regimens that increase the efficacy, given the context, are thus of importance...

Development of immunotherapy has dramatically changed poor prognosis of metastatic malignant melanoma (MM). Inhibition of immune checkpoints represents a new effective treatment. Monoclonal antibodies against CTLA-4 ipilimumab and against PD-1 (programme death 1) nivolumab and pembrolizumab prolong progression free survival and overall survival (OS) in patients with advanced metastatic MM. Both achieved significant improvement in relapse-free survival and OS also in adjuvant setting. It looks like the efficacy of the combined immunotherapy of ipilimumab with anti-PD-1 antibodies is superior to the monotherapy, but combined therapy is accompanied by higher toxicity...

Š Houdek, T Büchler, E Kindlová
BACKGROUND: Immunotherapy is a relatively new and developing modality in oncological treatment, which may significantly improve treatment results for some patients with malignant tumors. With the increasing number of clinical trials, the demand for a suitable tool to assess and compare treatment responses is growing. Currently, the most common response assessment system for solid tumors is RECIST (response Evaluation Criteria in Solid Tumors) version 1.1. However, in immuno-oncology, a small percentage of patients manifest a new response pattern termed pseudoprogression, in which, after the initial increase in tumor burden or after the discovery of new lesions, a response or at least a prolonged stabilization of the disease can occur...

BACKGROUND: Lung cancer occupies the leading position of cancer incidence and mortality worldwide, including in the Czech Republic. Despite significant advances in systemic oncology treatments, lung cancer still has the worst prognosis, which is driving the need for innovative therapies and methods to treat this disease. Immunotherapy is a developing area of systemic oncology treatment, which has recently begun to be significantly applied to patients with lung carcinoma. The most useful type of immunotherapy currently employs checkpoint inhibitors, including CTLA-4 inhibitors (ipilimumab and tremelimumab) and PD-1/PD-L1 inhibitors (nivolumab, pembrolizumab, durvalumab, and avelumab)...

P Dundr, K Němejcová, M Bártů, R Matěj, Z Rohan, I Tichá
BACKGROUND: The tumor microenvironment plays an important role in tumorigenesis and the tumor-host relationship. An important part of the tumor microenvironment is inflammatory infiltration. Its evaluation in solid tumors has prognostic meaning and appears also to be predictive of outcome, which is particularly important for predicting responses to immune checkpoint inhibitors. However, the methodology used to assess inflammatory infiltration is problematic, because it has been standardized only for certain types of tumors...

Urothelial carcinoma is the most common urological malignancy. Nonspecific immunotherapy using the Bacillus Calmette-Guerin vaccine has long been the mainstay for the treatment of high-risk superficial bladder carcinoma in an adjuvant setting after transurethral endoscopic resection. In metastatic disease, cisplatin-based chemotherapy remains the main therapeutic modality. In Europe, the standard second-line chemotherapy for patients with cisplatin-refractory tumours is vinflunine. Other systemic treatments with a lower level of evidence include paclitaxel and docetaxel...

BACKGROUND: The world population is mostly male at birth, although there is a shift in predominance over 55 years of age with more females than males. Male gender was recently hypothesized to be a risk factor for sepsis and septic shock; the reasons and the consequences of this odd discrepancy are yet a matter of debate. We investigated the percentage of males and females in a large number of trials performed on septic adult patients admitted to Intensive Care Units. METHODS: We analysed all the multicentre randomized controlled trials ever published in peer-reviewed Journals reporting a significant effect on mortality in intensive care unit septic adult patients; furthermore, we retrieved all the manuscripts dealing with sepsis or septic shock patients published in the last 3 years in the three medical Journals with the highest impact factor...
