Introduction: Correlating patients' chemotherapy-induced nausea and vomiting (CINV) experience with clinicians' understanding of the symptom severity and the patients' and clinicians' symptom management goals would aid in advancing symptom management. Identifying rankings of symptom severity after chemotherapy would help prioritizing symptom management.
Objective: The purpose of this study was to investigate and compare patients' CINV experience and clinicians' awareness of symptoms and symptom management goals. The study also aimed to identify and compare rankings of the severity of symptoms after chemotherapy by patients and clinicians.
Methods: A prospective observational study was conducted. Cancer patients starting the first adjuvant highly emetogenic chemotherapy (HEC) or moderately emetogenic chemotherapy (MEC) (n = 313), and oncology clinicians at two university hospitals (n = 73) in Korea participated in the study. The Multinational Association of Supportive Care in Cancer Antiemesis Tool (MAT) items and 20-symptom list were used to generate a symptom diary and survey questions. Descriptive statistics with a 95 % confidence interval and the Mann-Whitney U test were used to analyze the data.
Results: In general, clinicians overestimated the patients' CINV experience. Patients' symptom experiences and clinicians' estimates only corresponded for delayed nausea after the second cycle MEC. For symptom management goals, patients aimed for absolute vomiting control and avoiding significant nausea. Patients' symptom management goals exceeded the clinicians' goals for CINV control except for the goal for delayed nausea control. Clinicians rated chemotherapy-induced nausea as the most problematic symptom followed by vomiting; however, fatigue and loss of appetite were the top rated symptoms by patients.
Conclusions: Gaps exist between patients' symptom experience and clinicians' symptom awareness. Clinicians overestimated the patients' CINV experience and set less stringent symptom control goals. Enhancing clinicians' understanding of patients' symptom experience and retargeting the CINV management goals are the next steps for advancing symptom management. Symptoms other than CINV require more attention to set symptom management priorities reflecting patient experience and clinical significance.

Background/objectives: Millions of individuals worldwide continue to experience symptoms following SARS-CoV-2 infection. This study aimed to assess the prevalence and phenotype of multi-system symptoms attributed to Long COVID-including fatigue, pain, cognitive-emotional disturbances, headache, cardiopulmonary issues, and alterations in taste and smell-that have persisted for at least two years after acute infection, which we define as "persistent Long COVID". Additionally, the study aimed to identify clinical features and blood biomarkers associated with persistent Long COVID symptoms.

In this study, we introduce a novel approach that integrates interpretability techniques from both traditional machine learning (ML) and deep neural networks (DNN) to quantify feature importance using global and local interpretation methods. Our method bridges the gap between interpretable ML models and powerful deep learning (DL) architectures, providing comprehensive insights into the key drivers behind model predictions, especially in detecting outliers within medical data. We applied this method to analyze COVID-19 pandemic data from 2020, yielding intriguing insights.

(1) Background: Delirium is a serious condition in patients undergoing treatment for somatic diseases, leading to poor prognosis. However, the pathophysiology of delirium is not fully understood and should be clarified for its adequate treatment. This study analyzed the relationship between confusion symptoms in delirium and resting-state electroencephalogram (EEG) power spectrum (PS) profiles to investigate the heterogeneity.

Chronic pruritus, or persistent itching, is a debilitating condition that severely impacts quality of life, especially in palliative care settings. Traditional treatments often fail to provide adequate relief or are associated with significant side effects, prompting interest in alternative therapies. This review investigates the antipruritic potential of eight medicinal plants: chamomile (), aloe vera (), calendula (), curcumin (), lavender (), licorice (), peppermint (), and evening primrose ().

Recently, fecal microbiota transplantation (FMT) has been introduced as an effective treatment option for infection (CDI). However, the risk factors associated with FMT treatment failure have not been well demonstrated. Therefore, we aimed to investigate the risk factors of treatment failure or recurrence after FMT for CDI.
