Clinical significance of P-class pumps in cancer (Review)
P-class pumps are specific ion transporters involved in maintaining intracellular/extracellular ion homeostasis, gene transcription, and cell proliferation and migration in all eukaryotic cells. The present review aimed to evaluate the role of P-Type pumps [Na+/K+ ATPase (NKA), H+/K+ ATPase (HKA) and Ca2+-ATPase] in cancer cells across three fronts, namely structure, function and genetic expression. It has been shown that administration of specific P-class pumps inhibitors can have different effects by: i) Altering pump function; ii) inhibiting cell proliferation; iii) inducing apoptosis; iv) modifying metabolic pathways; and v) induce sensitivity to chemotherapy and lead to antitumor effects. For example, the NKA ÎČ2 subunit can be downregulated by gemcitabine, resulting in increased apoptosis of cancer cells. The sarcoendoplasmic reticulum calcium ATPase can be inhibited by thapsigargin resulting in decreased prostate tumor volume, whereas the HKA α subunit can be affected by proton pump inhibitors in gastric cancer cell lines, inducing apoptosis. In conclusion, the present review highlighted the central role of P-class pumps and their possible use and role as anticancer cellular targets for novel therapeutic chemical agents
Burnout and motivation to study medicine among students during the COVID-19 pandemic
AimTo investigate medical studentsâ burnout and motivation levels in each of the six years of their studies during the COVID-19 pandemic and identify independent predictors of burnout and motivation.MethodsAn anonymous cross-sectional survey was sent to the students of all six years within our school. Burnout was measured with the adapted Oldenburg Burnout Inventory questionnaire (OLBI-S) and motivation with the updated Strength of Motivation for Medical School (SMMS-R) questionnaire. Univariate analysis was performed with the KruskalâWallis test and Spearmanâs correlation, while multivariable analysis with linear regression models.ResultsA total of 333 medical students (52% of student body) responded. Higher burnout levels correlated with lower motivation to study medicine (rhoâ=ââ0.30, pâ<â0.001). Burnout levels differed between the six years of medical studies, peaking in years two and four whereas being the lowest in year one (pâ=â0.01). Motivation levels differed significantly as well, peaking in years one and four whereas being the lowest in years five and six (pâ=â0.012). In the multivariable linear regression models, being a female (bâ=â2.22, pâ=â0.016), studying in the fourth year vs. first year (bâ=â2.54, pâ=â0.049), having a perceived beginner/intermediate vs. advanced/expert technology level (bâ=â2.05, pâ=â0.032) and a perceived poor school support system (bâ=â6.35, pâ<â0.001) were independently associated with higher burnout levels. Furthermore, studying in the fifth year vs. first year (bâ=ââ5.17, pâ=â0.019) and a perceived poor school support system (bâ=ââ3.09, pâ=â0.01) were independently associated with a reduced motivation to study medicine.ConclusionOur study highlighted potential areas for intervention to decrease the rate of burnout and low motivation among medical students. However, further research is needed to unravel the full effect of the pandemic on medical students

Education and training programmes for infection prevention and control professionals: mapping the current opportunities and local needs in European countries.
BACKGROUND: Studies have repeatedly highlighted the need for homogenisation of training content and opportunities in infection prevention and control (IPC) across European countries.
OBJECTIVES: To map current training opportunities for IPC professionals, define local needs and highlight differences, across 11 European countries (Cyprus, France, England, Germany, Greece, Italy, Netherlands, Poland, Romania, Spain, Switzerland).
SOURCES: From July 2018 to February 2019, IPC experts directly involved in IPC training and education in their countries and/or internationally were invited to complete a prespecified set of questions in order to provide a detailed description of IPC training opportunities and needs in their country.
CONCLUSIONS: IPC training among nurses and doctors varies greatly across countries, with differences in content and type of training (e.g., standardised curriculum, educational programme, clinical experience) duration, as well as in assessment and recognition/accreditation. The observed heterogeneity in IPC training between European countries can be eliminated through establishment of interdisciplinary region-wide training programmes, with common learning objectives, shared know-how and supported by national and international professional bodies

Optimising antimicrobial use in humans â review of current evidence and an interdisciplinary consensus on key priorities for research
Data sharing: The data used to inform this policy paper can be made able, upon reasonable request from Esmita Charani, [email protected] © 2021 The Author(s). Addressing the silent pandemic of antimicrobial resistance (AMR) is a focus of the 2021 G7 meeting. A major driver of AMR and poor clinical outcomes is suboptimal antimicrobial use. Current research in AMR is inequitably focused on new drug development. To achieve antimicrobial security we need to balance AMR research efforts between development of new agents and strategies to preserve the efficacy and maximise effectiveness of existing agents. Combining a review of current evidence and multistage engagement with diverse international stakeholders (including those in healthcare, public health, research, patient advocacy and policy) we identified research priorities for optimising antimicrobial use in humans across four broad themes: policy and strategic planning; medicines management and prescribing systems; technology to optimise prescribing; and context, culture and behaviours. Sustainable progress depends on: developing economic and contextually appropriate interventions; facilitating better use of data and prescribing systems across healthcare settings; supporting appropriate and scalable technological innovation. Implementing this strategy for AMR research on the optimisation of antimicrobial use in humans could contribute to equitable global health security.Wellcome Trust; Economic and Social Research Council (ESRC); National Institute for Health Research ASPIRES project (Antibiotic use across Surgical Pathways: Investigating, Redesigning and Evaluating Systems) (https://www.imperial.ac.uk/arc/aspires/); National Institute for Health Research, UK Department of Health [HPRU-2012-10047] in partnership with Public Health England

Organization and training at national level of antimicrobial stewardship and infection control activities in Europe: an ESCMID cross-sectional survey
Antimicrobial stewardship (AMS) and Infection prevention and control (IPC) are two key complementary strategies that combat development and spread of antimicrobial resistance. The ESGAP (ESCMID Study Group for AMS), EUCIC (European Committee on Infection Control) and TAE (Trainee Association of ESCMID) investigated how AMS and IPC activities and training are organized, if present, at national level in Europe. From February 2018 to May 2018, an internet-based cross-sectional survey was conducted through a 36-item questionnaire, involving up to three selected respondents per country, from 38 European countries in total (including Israel), belonging to the ESGAP/EUCIC/TAE networks. All 38 countries participated with at least one respondent, and a total of 81 respondents. Education and involvement in AMS programmes were mandatory during the postgraduate training of clinical microbiology and infectious diseases specialists in up to one-third of countries. IPC was acknowledged as a specialty in 32% of countries. Only 32% of countries had both guidance and national requirements regarding AMS programmes, in contrast to 61% for IPC. Formal national staffing standards for AMS and IPC hospital-based activities were present in 24% and 63% of countries, respectively. The backgrounds of professionals responsible for AMS and IPC programmes varied tremendously between countries. The organization and training of AMS and IPC in Europe are heterogeneous and national requirements for activities are frequently lacking
Anticipating the Unpredictable: A Review of Antimicrobial Stewardship and Acinetobacter Infections
International nosocomial infection control consortium (INICC) report, data summary of 36 countries, for 2004-2009
The results of a surveillance study conducted by the International Nosocomial Infection Control Consortium (INICC) from January 2004 through December 2009 in 422 intensive care units (ICUs) of 36 countries in Latin America, Asia, Africa, and Europe are reported. During the 6-year study period, using Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN; formerly the National Nosocomial Infection Surveillance system [NNIS]) definitions for device-associated health care-associated infections, we gathered prospective data from 313,008 patients hospitalized in the consortium's ICUs for an aggregate of 2,194,897 ICU bed-days. Despite the fact that the use of devices in the developing countries' ICUs was remarkably similar to that reported in US ICUs in the CDC's NHSN, rates of device-associated nosocomial infection were significantly higher in the ICUs of the INICC hospitals; the pooled rate of central line-associated bloodstream infection in the INICC ICUs of 6.8 per 1,000 central line-days was more than 3-fold higher than the 2.0 per 1,000 central line-days reported in comparable US ICUs. The overall rate of ventilator-associated pneumonia also was far higher (15.8 vs 3.3 per 1,000 ventilator-days), as was the rate of catheter-associated urinary tract infection (6.3 vs. 3.3 per 1,000 catheter-days). Notably, the frequencies of resistance of Pseudomonas aeruginosa isolates to imipenem (47.2% vs 23.0%), Klebsiella pneumoniae isolates to ceftazidime (76.3% vs 27.1%), Escherichia coli isolates to ceftazidime (66.7% vs 8.1%), Staphylococcus aureus isolates to methicillin (84.4% vs 56.8%), were also higher in the consortium's ICUs, and the crude unadjusted excess mortalities of device-related infections ranged from 7.3% (for catheter-associated urinary tract infection) to 15.2% (for ventilator-associated pneumonia).
