Relationship of weight loss to quality of life and symptom distress among postsurgical survivors of oesophageal cancer who received chemotherapy.

PURPOSE: Weight loss is highly prevalent in oesophageal cancer survivors, who often experience disease-related or treatment-related symptoms and quality of life (QoL) impairment. This study aimed to explore the relationships among weight loss, symptom distress, and QoL postoperatively in patients with oesophageal cancer undergoing chemotherapy and to identify the factors influencing the QoL. METHODS: We conducted a retrospective observational study with 101 patients and collected data on weight loss (percentage of total body mass loss), QoL (EORTC-QLQ-C30 and EORTC-QLQ-OES-18), and symptom distress (MDASI-GI-C). The associations among weight loss, QoL, and symptom distress were assessed using Pearson's correlation. Multiple linear regression analysis was used to identify independent factors influencing patients' QoL scores. RESULTS: The distribution of weight loss of each stage in survivors of oesophageal cancer was 1.00% (SD: 2.48%), 4.69% (SD: 4.73%), 1.66% (SD: 5.37%), 2.83% (SD: 4.89%) respectively. The mean QoL score was 66.24 (SD 18.65). The participants' mean symptom severity and symptom interference scores were 3.30 (SD 1.74) and 2.76 (SD 1.90), respectively. Weight loss and symptom distress were negatively related to patients' QoL (p < 0.05, p < 0.01, respectively). Weight loss between 6 months before diagnosis and the time of diagnosis (p < 0.05) and symptom interference (p < 0.01) were independent predictors for the QoL. CONCLUSIONS: This study suggests that oesophageal cancer survivors with larger weight reduction between 6 months before diagnosis and the time of diagnosis and more symptom distress have a worse QoL. Clinicians should focus more on patients' weight and symptom management to improve their QoL.

Effects of Patient-Reported Outcome Tracking and Health Information Provision via Remote Patient Monitoring Software on Patient Outcomes in Oncology Care: A Systematic Review and Meta-Analysis.

OBJECTIVES: The authors sought to 1) review the literature on the remote care model that uses remote patient monitoring software (RPMS) as key mechanisms in oncology care for symptom tracking and health information provision and (2) compare the remote care model to standard care in terms of health-related quality of life, symptom burden, health management self-efficacy, anxiety, and depression. DATA SOURCES: The search was conducted on March 23, 2022, in the Cochrane Library, MEDLINE/PubMed, PsycINFO, and CINAHL databases. RESULTS: The primary strategies for applying digital technology in remote care models are patient-reported outcomes (PRO) tracking and health information delivery. Common PRO measurements applied in the RPMS include quality of life, symptom burden, self-efficacy, anxiety, and depression. Nine randomized controlled trials testing seven RPMS interventions were examined. Compared to standard care, remote patient monitoring via RPMS was related to greater quality of life and lower physical symptom burden during cancer therapy. The RPMS incorporated into routine clinical care with nurses providing remote monitoring performed better on PRO than that not integrated. CONCLUSION: The RPMS-based remote care model improves patient outcomes during cancer treatment, and it is not inferior to standard care until the RPMS function is more integrated with existing clinical care. IMPLICATIONS FOR NURSING PRACTICE: Nurses are well-positioned to engage patients in self-care skills via RPMS and can play a vital role in integrating such a model of remote patient care into routine care practices.

Effectiveness of Pictorial Education Handout on Tracheostomy Care Self-efficacy in Patients With Head and Neck Cancer and Family Caregivers: A Pilot Quasi-Experimental Study.

BACKGROUND: Learning and performing tracheostomy care are challenging for laypersons. Effective pictorial patient education handouts are needed for nonprofessional individuals to learn health management skills. OBJECTIVES: The study aims to (1) evaluate the preliminary efficacy of the pictorial education handout on patients' and family members' self-efficacy in tracheostomy care and (2) identify demographic, psychological, and education-related factors associated with lower self-efficacy on tracheostomy care. INTERVENTIONS/METHODS: This was a preliminary pilot study with a pretest-posttest design. We recruited a total of 39 participants, including 22 patients with head and neck cancer-related tracheostomy and 17 family caregivers in 2021. All participants received A3-size (297 × 420 mm) pictorial patient education handouts on how to suction and how to clean their tracheostomy at home. RESULTS: Pictorial education handouts showed a medium to large effect size on self-efficacy in the patient (Cohen D = 0.46) and caregiver participants (Cohen D = 0.78). Participants with higher anxiety were associated with a greater gain in self-efficacy with the pictorial patient education handouts (r = 0.35, P = .027). CONCLUSIONS: Pictorial patient education handouts were effective tools for improving patients' and family caregivers' confidence in tracheostomy care, and it is particularly helpful for individuals with high anxiety with tracheostomy. IMPLICATION FOR PRACTICE: Clinical nurses should use the pictorial education handouts not only to assist patients and family members on learning and practicing tracheostomy care but also to relieve anxiety associated with tracheostomy care at home.

Acid-degradable nanocomposite hydrogel and glucose oxidase combination for killing bacterial with photothermal augmented chemodynamic therapy.

Bacterial infection often delays diabetic wound healing, and even causes serious life-threatening complications. Herein, we successfully developed a Cu2O/Pt nanocubes-dopping alginate (ALG)- hyaluronic acid (HA) hydrogel (Cu2O/Pt hydrogel) by simple assembly of the Cu2O/Pt nanocubes and the ALG-HA mixture. The Cu2O/Pt hydrogel combined with the glucose oxidase (GOx) can be used for photothermal- and starving-enhanced chemodynamic therapy (CDT) against Gram-negative and Gram-positive bacteria. The GOx can catalyze the glucose to produce gluconic acid and H2O2 for starvation therapy, following which the released Cu2O/Pt nanocubes react with H2O2 in the acidic microenvironment to generate highly cytotoxic hydroxyl radicals (·OH) for CDT. Additionally, the Cu2O/Pt hydrogel can release copper ions gradually with the decrease of pH induced by gluconic acid, which can increase the protein expression and secretion of vascular endothelial growth factor (VEGF) and promote endothelial cell proliferation, migration and angiogenesis, subsequently promoting diabetic wound healing in rats. Our results suggested that the Cu2O/Pt hydrogel combined with GOx may be a potential therapeutic approach for treating the infected diabetic wound.

Diagnostic Evaluation of Depression Screening Tools in Asian New Zealanders.

This study aimed to compare the Kessler Psychological Distress Scale (K10) and Short-Form 12-Item Health Survey Mental Component Score (SF-12 MCS) for the effectiveness as screening tools for depression in Asian New Zealanders. A national, representative New Zealand Health Survey (NZHS) data set was used. In total, 1,277 participants were included in the analyses. The sensitivity and specificity values, as well as the areas under the receiver operating characteristics curves (AUROC), for the K10 and the SF-12 MCS scores were examined. The AUROCs for K10 and SF-12 MCS were 0.787 (95% CI [0.736, 0.837]) and 0.725 (95% CI [0.656, 0.793]), respectively. A less than optimal sensitivity and positive predictive value of K10 support the need to reexamine the optimal cut-off point according to the results of the Youden index. Strengthening the K10 predictive accuracy will increase the practical application among Asian populations.

Integrated Analysis Reveals the Gut Microbial Metabolite TMAO Promotes Inflammatory Hepatocellular Carcinoma by Upregulating POSTN.

Liver cancer has a high mortality rate. Chronic inflammation is one of the leading causes of hepatocellular carcinoma. Recent studies suggested high levels of trimethylamine N-oxide (TMAO) may correlate with increased risk of inflammatory-induced liver cancer. However, the mechanisms by which TMAO promotes liver cancer remain elusive. Here, we established a model of inflammatory-induced liver cancer by treating Hepa1-6 cells and Huh7 cells with TNF-α. TMAO synergistically increased the proliferation, migration and invasion of Hepa1-6 cells and Huh7 cells in the presence of TNF-α. We conducted bulk RNA-Seq of the TMAO-treated cell model of inflammatory Hepatocellular carcinoma (HCC) and evaluated the influence of the differentially expressed genes (DEGs) on clinical prognosis using Kaplan-Meier Plotter Database and Gene Expression Profiling Interactive Analysis (GEPIA) database. Univariate and multivariate Cox regression analyses of tumor microenvironment and DEGs were performed using Timer2.0. Upregulation of POSTN, LAYN and HTRA3 and downregulation of AANAT and AFM were positively related to poorer overall survival in human liver cancer. Moreover, higher expression of POSTN and HTRA3 positively correlated with infiltration of neutrophils, which can promote tumor progression. In vitro experiments showed TMAO activates ILK/AKT/mTOR signaling via POSTN, and knocking down POSTN significantly reduced ILK/AKT/mTOR signaling and the tumorigenicity of Hepa1-6 cells and Huh7 cells. Collectively, our results suggest the gut microbial metabolite TMAO and POSTN may represent potential therapeutic targets for liver cancer.

Post-Traumatic Distress and Symptom Experience in Patients With Head and Neck Cancer-Related Tracheostomy and Family Caregivers.

OBJECTIVES: To describe post-traumatic distress and identify associated factors in patients with head and neck cancer-related tracheostomy and their family caregivers. SAMPLE & SETTING: This observational study assessed 22 patients with surgically managed head and neck cancer-related tracheostomy and 17 family caregivers at a comprehensive cancer center. METHODS & VARIABLES: Instruments included the Impact of Event Scale-Revised, the Memorial Symptom Assessment Scale, and the Patient-Reported Outcomes Measurement Information System Depression 6a Short Form scale. RESULTS: Post-traumatic distress related to tracheostomy and general depression in patients and family caregivers was highly prevalent. An increased level of physical symptoms was moderately correlated with higher levels of post-traumatic distress. IMPLICATIONS FOR NURSING: Patients who experienced higher symptom burden may also suffer from post-traumatic distress related to tracheostomy. Oncology nurses can implement post-traumatic distress screening in patients and their family caregivers.

A Critical Review of Symptom Management Nursing Science on HIV-Related Fatigue and Sleep Disturbance.

Despite improved antiretroviral treatments, people living with HIV (PLWH) continue to suffer from HIV-related fatigue and sleep disturbances. We first reviewed the definition, etiology, and research breakthroughs of HIV-related fatigue and sleep disturbances, then analyzed nurse-led symptom management studies to describe their efficacy and make recommendations for future symptom research. We searched PubMed, CINAHL, PsycInfo, Psych and Behavioral Sciences Collection, and Scopus to identify nurse-led studies on symptom management for PLWH in the past 20 years. A total of 13 experimental or quasi-experimental studies were identified. The types of interventions included exercise, cognitive behavioral therapy, coaching, and symptom management manualized self-care activities. Currently, we cannot recommend with certainty any of the tested symptom management strategies to reduce fatigue or sleep disturbances. The current findings need to be confirmed and expanded to understand optimal dosing and sustainability.

Needs of Informal Caregivers of Patients With Head and Neck Cancer: A Systematic Review.

PROBLEM IDENTIFICATION: Informal caregivers for patients with head and neck cancer perform complex caregiving tasks on a daily basis, but caregivers' needs are rarely acknowledged or addressed in current healthcare practice. LITERATURE SEARCH: A thorough review of CINAHL®, MEDLINE®/PubMed®, and PsycINFO® was conducted by the authors. DATA EVALUATION: 266 manuscripts were identified, with no time limit. The search was conducted in November 2019. In total, 19 articles were included in the review. SYNTHESIS: Throughout the disease trajectory, caregivers' psychological and emotional support needs are consistently high, whereas information needs diminish over time. IMPLICATIONS FOR PRACTICE: Informal caregivers are imperative in supplementing the continuing care demands of people living with head and neck cancer; however, they are at risk for experiencing caregiving burden. Skill training and psychological support interventions are needed for educating and supporting caregivers.

Development of a gene-editing approach to restore vision loss in Leber congenital amaurosis type 10.

Leber congenital amaurosis type 10 is a severe retinal dystrophy caused by mutations in the CEP290 gene1,2. We developed EDIT-101, a candidate genome-editing therapeutic, to remove the aberrant splice donor created by the IVS26 mutation in the CEP290 gene and restore normal CEP290 expression. Key to this therapeutic, we identified a pair of Staphylococcus aureus Cas9 guide RNAs that were highly active and specific to the human CEP290 target sequence. In vitro experiments in human cells and retinal explants demonstrated the molecular mechanism of action and nuclease specificity. Subretinal delivery of EDIT-101 in humanized CEP290 mice showed rapid and sustained CEP290 gene editing. A comparable surrogate non-human primate (NHP) vector also achieved productive editing of the NHP CEP290 gene at levels that met the target therapeutic threshold, and demonstrated the ability of CRISPR/Cas9 to edit somatic primate cells in vivo. These results support further development of EDIT-101 for LCA10 and additional CRISPR-based medicines for other inherited retinal disorders.

UDiTaS™, a genome editing detection method for indels and genome rearrangements.

BACKGROUND: Understanding the diversity of repair outcomes after introducing a genomic cut is essential for realizing the therapeutic potential of genomic editing technologies. Targeted PCR amplification combined with Next Generation Sequencing (NGS) or enzymatic digestion, while broadly used in the genome editing field, has critical limitations for detecting and quantifying structural variants such as large deletions (greater than approximately 100 base pairs), inversions, and translocations. RESULTS: To overcome these limitations, we have developed a Uni-Directional Targeted Sequencing methodology, UDiTaS, that is quantitative, removes biases associated with variable-length PCR amplification, and can measure structural changes in addition to small insertion and deletion events (indels), all in a single reaction. We have applied UDiTaS to a variety of samples, including those treated with a clinically relevant pair of S. aureus Cas9 single guide RNAs (sgRNAs) targeting CEP290, and a pair of S. pyogenes Cas9 sgRNAs at T-cell relevant loci. In both cases, we have simultaneously measured small and large edits, including inversions and translocations, exemplifying UDiTaS as a valuable tool for the analysis of genome editing outcomes. CONCLUSIONS: UDiTaS is a robust and streamlined sequencing method useful for measuring small indels as well as structural rearrangements, like translocations, in a single reaction. UDiTaS is especially useful for pre-clinical and clinical application of gene editing to measure on- and off-target editing, large and small.
