The role of neoadjuvant chemotherapy in the management of advanced ovarian cancer in geriatric patients

It is increasingly common for ovarian cancer to affect older women, with over half of all cases involving patients aged 65 years and older. Unfortunately, elderly patients with ovarian malignancy tend to be treated less aggressively than younger patients, with less extensive surgery and less intensive chemotherapy regimens. This is due to a variety of factors, such as overall medical fitness and the function of specific organs. Moreover, multiple morbidities are typical for geriatric patients and affect their eligibility for certain forms of cancer therapy as well as their treatment outcomes, which are commonly less satisfactory than in younger patients. Additionally, for fear of complications, treating physicians sometimes limit the extent of the necessary surgery, or adjust chemotherapy doses, even though such a course of management tends to be largely misguided. One available management option is neoadjuvant chemotherapy followed by a surgical treatment known as interval debulking surgery. This type of combination therapy is associated with fewer postoperative complications, thus increasing the patient's chances of receiving a full course of adjuvant treatment. The decision to begin treatment with neoadjuvant chemotherapy tends to restrict later surgical therapy; however, under certain circumstances, this therapy can be a valid therapeutic option and, in fact, facilitate surgery. Prior to initiating therapy in elderly patients, their eligibility for combination therapy must be evaluated and the geriatric assessment of their performance and condition must be considered during the course of interdisciplinary preoperative management

The impact of artificial sweeteners on the risk and course of large intestinal adenocarcinoma in the elderly

There are many confirmed risk factors for development of the colorectal cancer, which is one of the most common malignant tumor among both females and males. Moreover, it is a cause of significant percentage of all cancer-related deaths. Even with treatment, the 5-year survival rate is very low. We concentrate on impact of artificial sweeteners on risk and course of adenocarcinoma of colon

SYK inhibition targets acute myeloid leukemia stem cells by blocking their oxidative metabolism

Spleen tyrosine kinase (SYK) is an important oncogene and signaling mediator activated by cell surface receptors crucial for acute myeloid leukemia (AML) maintenance and progression. Genetic or pharmacologic inhibition of SYK in AML cells leads to increased differentiation, reduced proliferation, and cellular apoptosis. Herein, we addressed the consequences of SYK inhibition to leukemia stem-cell (LSC) function and assessed SYK-associated pathways in AML cell biology. Using gain-of-function MEK kinase mutant and constitutively active STAT5A, we demonstrate that R406, the active metabolite of a small-molecule SYK inhibitor fostamatinib, induces differentiation and blocks clonogenic potential of AML cells through the MEK/ERK1/2 pathway and STAT5A transcription factor, respectively. Pharmacological inhibition of SYK with R406 reduced LSC compartment defined as CD34+CD38-CD123+ and CD34+CD38-CD25+ in vitro, and decreased viability of LSCs identified by a low abundance of reactive oxygen species. Primary leukemic blasts treated ex vivo with R406 exhibited lower engraftment potential when xenotransplanted to immunodeficient NSG/J mice. Mechanistically, these effects are mediated by disturbed mitochondrial biogenesis and suppression of oxidative metabolism (OXPHOS) in LSCs. These mechanisms appear to be partially dependent on inhibition of STAT5 and its target gene MYC, a well-defined inducer of mitochondrial biogenesis. In addition, inhibition of SYK increases the sensitivity of LSCs to cytarabine (AraC), a standard of AML induction therapy. Taken together, our findings indicate that SYK fosters OXPHOS and participates in metabolic reprogramming of AML LSCs in a mechanism that at least partially involves STAT5, and that SYK inhibition targets LSCs in AML. Since active SYK is expressed in a majority of AML patients and confers inferior prognosis, the combination of SYK inhibitors with standard chemotherapeutics such as AraC constitutes a new therapeutic modality that should be evaluated in future clinical trials

External quality monitoring facilitates improvement in already well-performing stroke units: insights from RES-Q Poland

Introduction. The Registry of Stroke Care Quality (RES-Q) is used in Poland for quality monitoring by numerous hospitals participating in the Angels Initiative. Our aim was to assess the degree of improvement in highly stroke-oriented centres that report cases to the RES-Q each year. Material and methods. This retrospective analysis included Polish stroke units that from January 2017 to December 2020 contributed to the RES-Q at least 25 patients annually. Results. Seventeen out of 180 Polish stroke units reported patients each year (2017, n = 1,691; 2018, n = 2,986; 2019, n = 3,750; 2020, n = 3,975). The percentage of ischaemic stroke patients treated with alteplase remained stable (26%, 29%, 30% and 28%, respectively). The door-to-needle time progressively decreased, from a median 49 minutes to 32 minutes. The percentage of patients treated ≤ 60 minutes and ≤ 45 minutes significantly increased (from 68% to 86% and from 43% to 70%, respectively), with no change observed between 2019 and 2020. Despite a general improvement in dysphagia screening (81%, 91%, 98% and 99%), screening performed within the first 24h from admission became less frequent (78%, 76%, 69% and 65%). In-hospital mortality significantly increased (11%, 11%, 13% and 15%), while the proportion of patients discharged home remained stable. Conclusions. Quality-oriented projects facilitate the improvement of stroke care, even in centres demonstrating good baseline performance. Polish stroke units that consistently reported cases to the RES-Q demonstrated improvement in terms of door-to- -needle time and dysphagia screening. However, there is still a need to shorten the time to dysphagia screening, and carefully monitor stroke unit mortality following the COVID-19 pandemic

Analysis of the road safety assessment in the areas of road nodes : questionnaire surveys

Węzły drogowe stanowią jeden z najważniejszych elementów infrastruktury drogowej. Są to szczególne typy skrzyżowań, których budowa powoduje wzrost poziomu bezpieczeństwa ruchu drogowego na obszarach dróg szybkiego ruchu i autostrad. Błędnie zaprojektowany czy też niedostatecznie oznakowany i oświetlony węzeł drogowy może wprowadzać uczestników ruchu w błąd i powodować niebezpieczne sytuacje.

A comprehensive analysis of chemical and biological pollutants (natural and anthropogenic origin) of soil and dandelion (Taraxacum officinale) samples.

A range of analytical methods (GC-MS, LC-MS, voltammetry, microbiological and microscopic techniques, PCR) was used to assay a range of potential chemical and biological contaminants in soil and dandelion samples. The results provide the first comprehensive safety analysis of dandelion as a herbal product. Samples were collected from three different sites in Poland where the local population collects dandelion plants for their own consumption: Rudenka (a mountain meadow in the European Ecological Network of Natura 2000 protection area, free of agrotechnical treatments for over 30 years), Warszawa 1 (dense single-family housing with heavy traffic), and Warszawa 2 (recreation area with heavy traffic near a coal-fired heat and power plant). The assays of heavy metals and other chemical pollutants (PAHs, PCBs, dioxins, pesticides, mycotoxins) confirm that all collected soil and dandelion samples were chemically pure; however, 95 species of pathogenic bacteria were detected, including "carnivorous" Vibrio vulnificus, zoonotic Pasteurella pneumotropica, Pasteurella canis, Staphylococcus pseudintermedius, Staphylococcus lentus and Francisella tularensis as well as 14 species of pathogenic fungi and one protozoan parasite (Giardia intestinalis). The discovery of septicemia agents V. vulnificus, Fusobacterium mortiferum and Rahnella aquatilis in the soil surrounding dandelion roots and in the flowers, G. intestinalis in dandelion leaves and roots samples, all collected in Warsaw, is highly disturbing. This finding underlines the need for increased caution when collecting dandelion in densely populated areas with a large population of pets. Thorough washing of the harvested plants is necessary before using them for consumption, especially in the case of making salads from fresh dandelion leaves, which is becoming increasingly popular among people leading healthy and an environmentally friendly lifestyle

Synthetic lethality between VPS4A and VPS4B triggers an inflammatory response in colorectal cancer

Abstract Somatic copy number alterations play a critical role in oncogenesis. Loss of chromosomal regions containing tumor suppressors can lead to collateral deletion of passenger genes. This can be exploited therapeutically if synthetic lethal partners of such passenger genes are known and represent druggable targets. Here, we report that VPS4B gene, encoding an ATPase involved in ESCRT‐dependent membrane remodeling, is such a passenger gene frequently deleted in many cancer types, notably in colorectal cancer (CRC). We observed downregulation of VPS4B mRNA and protein levels from CRC patient samples. We identified VPS4A paralog as a synthetic lethal interactor for VPS4B in vitro and in mouse xenografts. Depleting both proteins profoundly altered the cellular transcriptome and induced cell death accompanied by the release of immunomodulatory molecules that mediate inflammatory and anti‐tumor responses. Our results identify a pair of novel druggable targets for personalized oncology and provide a rationale to develop VPS4 inhibitors for precision therapy of VPS4B‐deficient cancers
