    Abstract Purpose: To determine the significance to patients of changes in health-related quality-of-life (HLQ) scores assessed by the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30).
    Patients and methods: A subjective significance questionnaire (SSQ), which asks patients about perceived changes in physical, emotional, and social functioning and in global quality of life (global QL) and the QLQ-C30 were completed by patients who received chemotherapy for either breast cancer or small-cell lung cancer (SCLC). In the SSQ, patients rated their perception of change since the last time they completed the QLQ-C30 using a 7-category scale that ranged from "much worse" through "no change" to "much better." For each category of change in the SSQ, the corresponding differences were calculated in QLQ-C30 mean scores and effect sizes were determined.
    Results: For patients who indicated "no change" in the SSQ, the mean change in scores in the corresponding QLQ-C30 domains was not significantly different from 0. For patients who indicated "a little" change either for better or for worse, the mean change in scores was about 5 to 10; for "moderate" change, about 10 to 20; and for "very much" change, greater than 20. Effect sizes increased in concordance with increasing changes in SSQ ratings and QLQ-C30 scores.
    Conclusion: The significance of changes in QLQ-C30 scores can be interpreted in terms of small, moderate, or large changes in quality of life as reported by patients in the SSQ. The magnitude of these changes also can be used to calculate the sample sizes required to detect a specified change in clinical trials.

    Abstract: Introduction: The virulence binding factor, protective antigen (pag) and poly-D-γ-glutamate ...

    Abstract Introduction: The virulence binding factor, protective antigen (pag) and poly-D-γ-glutamate capsular (cap) genes, peculiar to Bacillus anthracis are located in the pXO1 and pXO2 plasmids which are transferable horizontally to related species called "cereus group". The cereus group are usually isolated from the environmental/food samples and have been implicated in debilitating human and animal anthrax-like diseases. This study was designed to investigate the presence of the anthrax virulence genes in different Bacillus spp. isolated from handwashing facilities during COVID-19 pandemic in Lagos, Nigeria.
    Methodology: The Bacillus anthracis (OK316847), B. thuringiensis (OK316855), B. amyloliquefaciens (OK316857), B. cereus (OK316858) and B. thuringiensis (OK316859) previously isolated from rinsates and bowl water in two local government areas (LGAs) of Lagos state were further investigated by the polymerase chain reaction (PCR) amplification of the pag and cap genes using specific primers.
    Results: Bacillus anthracis and B. cereus co-harboured the two 578 bp cap and 364 bp pag genes while B. thuringiensis only harboured the cap gene. Similarly, the non-cereus B. amyloliquefaciens was found to habour the pag gene.
    Conclusions: The two anthrax toxin genes were amplified in the Bacillus spp isolated from rinsates and bowl water used in hand washing in the two study LGAs. Given that these virulence genes have a global consequence and are a potential threat to life, this study calls for an extensive surveillance, and reassessment of gene regulators and plasmid distribution among these strains in our environment.

    Abstract The measurement of patient-reported outcomes, including health-related quality of life, is a new initiative which has emerged and grown over the past four decades. Following the development of reliable and valid self-report questionnaires, health-related quality of life has been assessed in tens of thousands of patients and a wide variety of cancers. This review is based on a selection of data published in the last decade and is intended primarily for healthcare professionals. The assessments in clinical trials have been particularly useful for elucidating the effects of various cancers and their treatments on patients' lives and have provided additional information that enhances the usual clinical endpoints used for determining the benefits and toxicity of treatment. With growing experience the quality of the health-related quality of studies has improved and, in general, recent studies are more likely to be methodologically robust than those that were performed in earlier decades. Health-related quality of life has become a more accurate predictor of survival than some other clinical parameters, such as performance status. The overall outlook for the routine assessment of patient-reported outcomes in clinical trials is assured and, eventually, it is likely to become a standard part of clinical practice. However, there is still a need for a clear method for determining the clinical meaningfulness of changes in scores. The answer will probably come from the greater use of patient-reported outcomes and the consequent growth of experience that is necessary to make such judgements.

    Abstract Patient-reported outcomes (PROs) are based on direct reporting by patients without the intervention of an observer. They include the self-assessment of functional status, symptoms, and other concerns such as needs and satisfaction with care. Health-related quality of life (HRQOL) assessment is a form of PRO and often includes both functional status and symptoms. The science underlying the assessment of HRQOL in clinical practice requires an understanding of the relationships between symptoms, functional status, and HRQOL, as well as instrument selection, and analysis and interpretation of the data. A modification of the Wilson and Cleary model is proposed to show the likelihood of bidirectional relationships between symptoms, functions, and HRQOL. Instrument selection should be based on the measurement properties of the instruments and patient populations in which they will be used. Analyses of data that allow a calculation of the proportion of patients who benefit from an intervention are preferred to analyses that show only the mean change in scores from baseline. HRQOL assessment in clinical practice has been shown to lead to a better understanding of patients' concerns with improvement in counseling and referral for required services. Potentially, HRQOL assessment should also be used to monitor the progress of a patient's disease and benefit from treatment.

    Abstract Algorithmic (including AI/ML) decision-making artifacts are an established and growing part of our decision-making ecosystem. They are indispensable tools for managing the flood of information needed to make effective decisions in a complex world. The current literature is full of examples of how individual artifacts violate societal norms and expectations (e.g. violations of fairness, privacy, or safety norms). Against this backdrop, this discussion highlights an under-emphasized perspective in the literature on assessing value misalignment in AI-equipped sociotechnical systems. The research on value misalignment has a strong focus on the behavior of individual tech artifacts. This discussion argues for a more structured systems-level approach for assessing value-alignment in sociotechnical systems. We rely primarily on the research on fairness to make our arguments more concrete. And we use the opportunity to highlight how adopting a system perspective improves our ability to explain and address value misalignments better. Our discussion ends with an exploration of priority questions that demand attention if we are to assure the value alignment of whole systems, not just individual artifacts.

    Abstract A primary objective of symptom control and supportive care in clinical trials is to improve health-related quality of life. However, in the past, most such clinical trials have concentrated on limited outcomes, such as control of anorexia or pain, and have not taken into account the broader outcome of health-related quality of life. The multidimensional tools needed to carry out these trials are now available, and several studies have yielded results that are informative and useful. These include studies on ameliorating anorexia and weight loss, fatigue and anemia, postchemotherapy nausea and vomiting, and pain from bone metastases. Examples of such studies are given. However, there is still much to learn, and investigators are urged to continue to measure health-related quality of life in clinical trials of symptom control and supportive care.

    Abstract Objectives: To propose a taxonomy of psychometrically based, health-related quality-of-life instruments related to three levels of decision-making of health care: the macro, meso and micro levels. The choice of appropriate health-related quality-of-life instruments for each level of desired decision making in various clinical settings is illustrated. A secondary objective was to describe solutions for some of the difficulties inherent in the interpretation of the results of health-related quality-of-life assessment.
    Design: The three main levels of clinical decision making are listed and the instruments used most frequently in cancer clinical trials are reviewed from the medical literature.
    Proposals: Generic and utility-based instruments are likely to be the most valuable at the macro level of decision making, whereas condition-specific, disease-specific, and situation-specific instruments are most useful for decision making at the meso and micro levels. A determination of the proportions of patients who have reached a meaningful change in health-related quality-of-life scores (eg, > or =10 for scales of 1-100) over a standard period is a rational approach to interpreting the significance of changes in scores.
    Conclusions: Awareness of the level of decision making that is involved in the clinical assessment of health-related quality of life can be helpful in choosing instruments that are appropriate for various clinical settings. Some of the difficulties in interpreting the meaning of changes in health-related quality-of-life scores can be overcome by comparing the proportions of patients who have achieved a preset magnitude of change.
