Immunohistochemical markers are associated with treatment outcome in adults with classical Hodgkin Lymphoma (cHL). Studies in children are scarce and inconsistent. We investigated in 67 children with cHL, whether the expression of CD15, CD30, PAX5, PD-1, PD-L1, CD68, CD163 and TARC at diagnosis is associated with disease free survival (DFS) and with interim remission status. Low CD15 and low TARC expression were associated with relapsed disease. Low expression of PD-L1 was associated with complete remission at interim PET-scan. Our data suggest a difference between pediatric and adult cHL. Panobinostat This underlines the importance of future research into specific prognostic factors in pediatric cHL, indispensable for improvement of treatment in this population.Tumour hypoxia is the inevitable consequence of a tumour's rapid growth and disorganized, inefficient vasculature. The compensatory mechanisms employed by tumours, and indeed the absence of oxygen itself, hinder the ability of all treatment modalities. The clinical consequence is poorer overall survival, disease-free survival, and locoregional control. Recognizing this, clinicians have been attenuating the effect of hypoxia, primarily with hypoxic modification or with hypoxia-activated pro-drugs, and notable success has been demonstrated. However, in the case of colorectal cancer (CRC), there is a general paucity of knowledge and evidence surrounding the measurement and modification of hypoxia, and this is possibly due to the comparative inaccessibility of such tumours. We specifically review the role of hypoxia in CRC and focus on the current evidence for the existence of hypoxia in CRC, the majority of which originates from indirect positron emission topography imaging with hypoxia selective radiotracers; the evidence correlating CRC hypoxia with poorer oncological outcome, which is largely based on the measurement of hypoxia inducible factor in correlation with clinical outcome; the evidence of hypoxic modification in CRC, of which no direct evidence exists, but is reflected in a number of indirect markers; the prognostic and monitoring implications of accurate CRC hypoxia quantification and its potential in the field of precision oncology; and the present and future imaging tools and technologies being developed for the measurement of CRC hypoxia, including the use of blood-oxygen-level-dependent magnetic resonance imaging and diffuse reflectance spectroscopy.

Paediatric stone disease is rare in the Nordic communities. Still, the condition can require surgical intervention in the form of ureteroscopy (URS). Here, we report outcomes achieved at a regional (tertiary) centre.

Retrospective analysis was performed of consecutive patients (<18 years of age) undergoing URS for stone disease between 2010 and 2021. Outcomes of interest included stone-free rate (SFR) determined using a definition of no residual fragments ⩾ 3 mm on imaging and complications classified according to Clavien-Dindo system.

In total, 23 patients underwent 47 URS procedures for a total of 31 stone episodes. Mean age was 9 (range 1-17) years and male-to-female ratio was 617. Overall, 35% had at least one medical comorbidity. Ultrasound determined preoperative stone status in 87%. Mean largest index and cumulative stone sizes were 9 (range 3-40) and 12 (range 3-40) mm, respectively. Overall, 32% had multiple stones. Lower pole was the commonest stone location (39%). No patients underwent elective pre-operative stenting. Ureteral access sheaths were not used in any cases. Access to upper urinary tract at first procedure was successful in 94%. Initial and final SFR was 61% and 90%, respectively. No intra-operative complications were recorded. Overall post-operative complication rate was 17.5%. Urinary tract infection (CD II) was the commonest adverse event (12.5%).

Paediatric URS can be delivered in the setting of a regional centre without compromising outcomes. This includes when carried out by adult endourologists, without routine pre-stenting and omitting use of ureteric access sheath.

This information is usually captured in qualitative data that requires manual analysis. Healthcare systems often lack resources to systematically incorporate qualitative feedback into decision making. Semi-automated content analysis tools, such as Leximancer, provide an efficient and objective alternative to time consuming manual content analysis (MCA). Literature on the validity of Leximancer in healthcare is sparse. This study seeks to validate Leximancer against MCA on a broad emotive conversational dataset gathered in a healthcare setting. At the outset of the COVID-19 pandemic, a large Australian hospital and health service conducted interactive webcasts with staff to provide updates and answer questions. A manual thematic analysis and a Leximancer content analysis were conducted independently on 20 webcast transcripts. The findings were compared, along with the time required to the complete each analysis. The Leximancer analysis identified nine concepts, while the manual analysis identified 12 concepts. The Leximancer concepts mapped to five of the concepts identified in the manual analysis, which accounted for 74% of mentions tagged in the text through the manual analysis. Leximancer missed concepts which required an emotional or contextual interpretation. The Leximancer analysis took 21 hours (excluding time to learn the program), compared to 73 hours for the manual analysis. Semi-automated content analysis provides an efficient alternative to manual qualitative data analysis, shifting it from a small-scale research activity to a more routine operational activity, albeit with some limitations. This is critical to be able to utilise at scale the rich narratives from consumers and clinicians in healthcare decision making.

To determine the prevalence of drug-related problems and the factors influencing them among adult psychiatric inpatients.

A multi-centre cross-sectional observational study was conducted from April to July 2021 at five randomly selected hospitals in Northwest Ethiopia. A total of 325 consecutively sampled patients participated in the study. Clinical pharmacists assessed the drug-related problems based on clinical judgement supported by updated evidence-based disease guidelines. We used the Medscape drug-interactions checker to check drug-to-drug interactions. The results were summarised using descriptive statistics, including frequency, mean, and standard deviation. For each variable, an odds ratio with a 95% confidence interval was calculated, as well as the related

-value. The value of

 ⩽ 0.05 was considered statistically significant.

From the total number of 325 study participants, more than half of them (52.9%) were females, and the mean age ± (standard deviation) was 30.8 ± 11.3 years. At leastric patients admitted to psychiatric wards was high. Healthcare providers give more attention to tackling these problems. Being a rural resident, self-employed, and alcohol drinkers were associated with drug-related problems.

Several safety-related accidents occur in the laboratories because of insufficient regulations, inappropriate implementation of safety measures, or unawareness attitude and practices toward safety precautions. Thus, establishment of efficient regulations and safe habits toward workplace safety is crucial to prevent or minimize such accidents. Here we investigate the levels of laboratory safety awareness among undergraduate medical science students and laboratory workers at major hospitals in Taif, Saudi Arabia.

An anonymous cross-sectional survey was conducted on a random sample of 185 students and workers. The survey was categorized into five sections (1) variable demographic items, (2) orientation around the warning signage of medical laboratory picograms, (3) assess participants' attitudes toward laboratory safety, (4) assess participants' safety awareness and practices in medical laboratories, and (5) assess participants' knowledge in dealing with emergency equipment and related procedures.

Data anatraining to improve student safety.Introduction Occupational health and safety management systems are widely used as a systematic approach to managing occupational health and safety. However, sometimes they are restrictive and underspecified to deal with dynamic workplace demands. Rasmussen used a model of boundaries to conceptualize this dynamic model of safety, where the space of possibilities lay within 3 boundaries and workers used various means to stay within the boundaries to remain both productive and safe at work. Methods This study applied the Rasmussen model of boundaries to understand the factors that formed the boundaries, the gradients, and countergradients in a biomedical laboratory. Results The most central goal was to be the first to publish, and this formed the boundary to scientific output failure; the boundary to unacceptable workload and boundary to functionally acceptable performance were the other 2 boundaries in line with the Rasmussen model. The workers had developed methods (mental risk assessment, teamwork, and experience and familiarity) of working, which ensured they remained productive and safe. This can be described as resilient performance, where resilience is not something that a system has but something it does to adjust their performance when faced with expected or unexpected changes. Discussion and Conclusion A customized portfolio of rule-based non negotiable instructions and a risk assessment-based approach would be best suited for a biomedical laboratory. The workers have learned resilient performance on their own and unknowingly are already practicing this. It is now time to formally incorporate such practices into the safety systems of biomedical laboratories.The coronavirus disease 2019 (COVID-19) that begun in December 2019 has spread worldwide and is caused by a novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV2). In the Philippines, the first case of COVID-19 was reported on January 20, 2020. Early in the SARS-CoV2 outbreak, clinical samples from suspected COVID-19 patients had to be sent to a reference laboratory in Australia for confirmation. However, as of November 11, 2020, there are now 164 Department of Health (DOH) licensed COVID-19 testing laboratories in the country. The Department of Health-Research Institute for Tropical Medicine (DOH-RITM) is the National Reference Laboratory for emerging and re-emerging infectious diseases. The RITM follows the guidelines set forth by the World Health Organization (WHO) when responding to outbreaks. One of its functions is to conduct risk assessment and proficiency testing to ensure and maintain the safety and high-quality performance of independent laboratories. The majority of the COVID-19 testing centers use a real-time reverse transcription-polymerase chain reaction platform.
