Translation and Psychometric Evaluation of the Hindi Language Version of the Pediatric Nausea Assessment Tool (PeNAT) in the Indian Population.

OBJECTIVES: To translate the Pediatric Nausea Assessment Tool (PeNAT) into Hindi and validate it in Indian pediatric cancer patients and survivors. METHODS: The PeNAT-Hindi was finalized by forward and backward translations, and pilot testing. The PeNAT-Hindi was administered to 200 Hindi-speaking pediatric (4-18 y) cancer patients/survivors, in three groups. These included pediatric cancer patients who had recently received chemotherapy (n = 150); who received no chemotherapy within 5 d (n = 25) and survivors (n = 25). Construct validity was tested by comparing scores among the three groups. Test-retest reliability and criterion validity were estimated by the correlation of the first PeNAT score with the second (taken 1 h later) PeNAT score and the number of vomiting/retching episodes, respectively. Convergent validity and discriminant validity were estimated by correlating PeNAT scores with parent-assessed nausea severity, and pain, respectively. The responsiveness was tested by comparing second PeNAT scores with subsequent divergent PeNAT scores among patients reporting subjective change (improvement and worsening, respectively) in nausea severity. RESULTS: Test-retest reliability of PeNAT-Hindi was good (intraclass correlation = 0.791). The initial PeNAT score had moderate correlation with the number of vomiting/retching episodes (Spearman ρ = 0.401). Median PeNAT scores in group 1 versus groups 2 and 3 were significantly different (p < 0.001). Initial PeNAT scores showed a moderate correlation with parent-assessed nausea (Spearman ρ = 0.657) and a weak correlation with parent-assessed pain (Spearman ρ = 0.319). The responsiveness (standardized response mean) of PeNAT-Hindi to the change in nausea severity was -1.79 (improvement) and 2.19 (worsening), respectively. CONCLUSION: PeNAT-Hindi showed good reliability and acceptable validity. It may be used among Hindi-speaking children for measuring nausea. The responsiveness of PeNAT-Hindi needs further evaluation.

A deep learning-based interpretable decision tool for predicting high risk of chemotherapy-induced nausea and vomiting in cancer patients prescribed highly emetogenic chemotherapy.

OBJECTIVE: This study aims to develop a risk prediction model for chemotherapy-induced nausea and vomiting (CINV) in cancer patients receiving highly emetogenic chemotherapy (HEC) and identify the variables that have the most significant impact on prediction. METHODS: Data from Tianjin Medical University General Hospital were collected and subjected to stepwise data preprocessing. Deep learning algorithms, including deep forest, and typical machine learning algorithms such as support vector machine (SVM), categorical boosting (CatBoost), random forest, decision tree, and neural network were used to develop the prediction model. After training the model and conducting hyperparameter optimization (HPO) through cross-validation in the training set, the performance was evaluated using the test set. Shapley additive explanations (SHAP), partial dependence plot (PDP), and Local Interpretable Model-Agnostic Explanations (LIME) techniques were employed to explain the optimal model. Model performance was assessed using AUC, F1 score, accuracy, specificity, sensitivity, and Brier score. RESULTS: The deep forest model exhibited good discrimination, outperforming typical machine learning models, with an AUC of 0.850 (95%CI, 0.780-0.919), an F1 score of 0.757, an accuracy of 0.852, a specificity of 0.863, a sensitivity of 0.784, and a Brier score of 0.082. The top five important features in the model were creatinine clearance (Ccr), age, gender, anticipatory nausea and vomiting, and antiemetic regimen. Among these, Ccr had the most significant predictive value. The risk of CINV decreased with increased Ccr and age, while it was higher in the presence of anticipatory nausea and vomiting, female gender, and non-standard antiemetic regimen. CONCLUSION: The deep forest model demonstrated good discrimination in predicting the risk of CINV in cancer patients prescribed HEC. Kidney function, as represented by Ccr, played a crucial role in the model's prediction. The clinical application of this predictive tool can help assess individual risks and improve patient care by proactively optimizing the use of antiemetics in cancer patients receiving HEC.

Waterpipe Tobacco (Hookah) Use in Pregnancy: Associations with Nausea and Vomiting of Pregnancy.

OBJECTIVE: Waterpipe tobacco (WPT) use is common among reproductive age patients and is often perceived as safer than cigarette use. Prior studies have shown a decrease in nausea and vomiting symptoms among pregnant women who use cigarettes, but no studies to date have examined these symptoms in pregnant women who use WPT. This study was aimed to investigate the extent of symptoms of nausea/vomiting of pregnancy among participants who self-reported WPT use during pregnancy. STUDY DESIGN: Secondary analysis of a prospective cohort study examining WPT use during pregnancy. Participants completed the Pregnancy-Unique Quantification of Emesis (PUQE) during first and third trimesters. Medical conditions were determined by medical record review. Participants were evaluated by sole WPT use versus dual/polysubstance WPT use and frequency of WPT use. RESULTS: Ninety-nine (100%) participants completed the PUQE questionnaire during first trimester and 82 (82.8%) completed the PUQE during third trimester. Almost all (91.9%) participants reported moderate nausea/vomiting symptoms at both assessments. There was no difference in frequency of WPT use in pregnancy or rates of dual/polysubstance WPT use in participants with all levels of the PUQE questionnaire. There was also no difference in rates of WPT use or PUQE scores between sole WPT users and dual/polysubstance users. When comparing low and high WPT use, those who were in the higher frequency use group had higher waterpipe dependence scale scores (7.2 vs. 5.3, p < 0.02). With regard to maternal medical comorbidities, the only difference between groups was that sole WPT users were more likely to have a diagnosis of asthma than dual/polysubstance users (36.8 vs. 14.9%, p < 0.02). CONCLUSION: There were no differences in symptoms of nausea and vomiting of pregnancy or medical conditions in pregnant women who use WPT with any frequency during pregnancy. However, sole WPT users had higher rates of asthma than dual/polysubstance WPT users. KEY POINTS: · Waterpipe tobacco use is one of the most common forms of tobacco use among reproductive age patients.. · Waterpipe tobacco use was not associated with any changes in nausea/vomiting of pregnancy symptoms.. · Future research on the use of waterpipe tobacco in pregnancy can aid in public health responses..

Evaluation of a nausea assessment tool in the pediatric oncology population.

PURPOSE: Nausea is a symptom that is often experienced but misunderstood. Its impact is amplified in pediatric oncology patients. Nausea assessments in pediatric oncology are few and not yet widely used. The Baxter Retching Faces (BARF) scale holds promise and is used in some pediatric oncology units. The purpose of this evidence-based practice project was to evaluate the impact of the BARF scale on nursing assessments in inpatient pediatric hematology/oncology and stem cell transplant settings. CONCLUSIONS: Project work took place on one hematology/oncology unit and one stem cell transplant unit. Thirty nurses completed the acceptability of intervention measure (AIM), intervention appropriateness measure (IAM), and feasibility of intervention measure (FIM) to provide initial feedback on the BARF scale. Nurses used the BARF scale over an 8-week period. Patient demographics and BARF scores were collected during nausea assessments. Twenty nurses completed AIM/IAM/FIM scores postintervention. There were no significant changes in scores, though nurses stated that the tool was easy to use and provided valuable symptom feedback. PRACTICE IMPLICATIONS: Symptom management will continue to be a challenge in the pediatric setting given developmental and disease-specific considerations inherent to the specialty. While this small-scale project did not achieve statistical significance, the evidence and feedback from nursing staff present a compelling case that efforts to investigate and integrate improved methods of assessing nausea and other problematic symptoms are needed to enhance nursing practice and impact patient-centered outcomes.

Developing the Nausea and Vomiting Thermometer Scale in children with cancer.

BACKGROUND: This study aimed to develop the Nausea and Vomiting Thermometer Scale (NVTS) in children with cancer. METHODS: This methodological study was conducted on 250 children with cancer at the research and training university hospital in Turkey between September 2019 and January 2020. The t-test, the ROC analysis, the Diagnostic index, and the Youden index were used for determining the scale of the cutting point. The regression analysis, the intra-class correlation coefficient, and the BlandAltman analysis were used for the data analysis. RESULTS: The scale-level content validity index was .94, which was coherent. As a result of the ROC analysis, the cut-off point was determined as three points. The NVTS showed good reliability, with an intra-class correlation coefficient of .99. In the linear regression analysis, a model was created for chemotherapy drugs, nausea and vomiting type, vomiting status, and the number of children with cancer who vomited explained 44.9% of their nausea and vomiting status. The results of the Bland-Altman analysis showed that the correlation coefficient between the differences and the means was insignificant.

Identification of Uncontrolled Symptoms in Cancer Patients Using Natural Language Processing.

CONTEXT: For patients with cancer, uncontrolled pain and other symptoms are the leading cause of unplanned hospitalizations. Early access to specialty palliative care (PC) is effective to reduce symptom burden, but more efficient approaches are needed for rapid identification and referral. Information on symptom burden largely exists in free-text notes, limiting its utility as a trigger for best practice alerts or automated referrals. OBJECTIVES: To evaluate whether natural language processing (NLP) can be used to identify uncontrolled symptoms (pain, dyspnea, or nausea/vomiting) in the electronic health record (EHR) among hospitalized cancer patients with advanced disease. METHODS: The dataset included 1,644 hospitalization encounters for cancer patients admitted from 1/2017 -6/2019. We randomly sampled 296 encounters, which included 15,580 clinical notes. We manually reviewed the notes and recorded symptom severity. The primary endpoint was an indicator for whether a symptom was labeled as "controlled" (none, mild, not reported) or as "uncontrolled" (moderate or severe). We randomly split the data into training and test sets and used the Random Forest algorithm to evaluate final model performance. RESULTS: Our models predicted presence of an uncontrolled symptom with the following performance: pain with 61% accuracy, 69% sensitivity, and 46% specificity (F1: 69.5); nausea/vomiting with 68% accuracy, 21% sensitivity, and 90% specificity (F1: 29.4); and dyspnea with 80% accuracy, 22% sensitivity, and 88% specificity (F1: 21.1). CONCLUSION: This study demonstrated initial feasibility of using NLP to identify hospitalized cancer patients with uncontrolled symptoms. Further model development is needed before these algorithms could be implemented to trigger early access to PC.

Randomized, Double-Blind, Phase III Study of Fosnetupitant Versus Fosaprepitant for Prevention of Highly Emetogenic Chemotherapy-Induced Nausea and Vomiting: CONSOLE.

PURPOSE: We evaluated the efficacy and safety of fosnetupitant (FosNTP) versus fosaprepitant (FosAPR) for preventing highly emetogenic chemotherapy-induced nausea and vomiting. This phase III study was the first head-to-head comparison between two different neurokinin-1 receptor antagonists in combination with palonosetron and dexamethasone. PATIENTS AND METHODS: Patients scheduled to receive cisplatin-based chemotherapy were randomly assigned 1:1 to FosNTP 235 mg or FosAPR 150 mg in combination with palonosetron 0.75 mg and dexamethasone. The primary end point was overall (0-120 hours) complete response (CR; no emetic event and no rescue medication) rate, stratified by sex and age category, to show the noninferiority of FosNTP to FosAPR (noninferiority margin, -10% for the difference in the overall CR rate). RESULTS: Overall, 795 patients were randomly assigned, of whom 785 received the study drug (FosNTP [N = 392] v FosAPR [N = 393]) and were evaluated for efficacy and safety. The overall CR rate was 75.2% versus 71.0%, respectively (Mantel-Haenszel common risk difference, 4.1%; 95% CI, -2.1% to 10.3%), demonstrating noninferiority of FosNTP to FosAPR. The CR rates in the acute (0-24 hours), delayed (24-120 hours), and beyond delayed (120-168 hours) phases, and at 0-168 hours were 93.9% versus 92.6%, 76.8% versus 72.8%, 86.5% versus 81.4%, and 73.2% versus 66.9%, respectively. The incidence rates of treatment-related adverse events with FosNTP versus FosAPR were 22.2% versus 25.4%, whereas adverse events or treatment-related adverse events relevant to injection site reactions were 11.0% versus 20.6% (P < .001) and 0.3% versus 3.6% (P < .001), respectively. CONCLUSION: FosNTP demonstrated noninferiority to FosAPR, with a favorable safety profile and lower risk for injection site reactions. Thus, FosNTP is valuable in the prophylaxis of acute, delayed, and beyond delayed chemotherapy-induced nausea and vomiting.

Efficacy of ondansetron against emesis induced by a multiple-day cisplatin-based chemotherapy regimen for malignant lymphoma.

OBJECTIVES: This study aimed to evaluate the antiemetic efficacy of a 5-hydroxytryptamine-3 receptor antagonist (5-HT3RA), ondansetron, in patients with malignant lymphoma receiving multi-day cisplatin-based combination chemotherapy. METHODS: We conducted a single-institution retrospective analysis of patients receiving the first course of an ESHAP (etoposide, cisplatin, methylprednisolone, cytarabine) regimen including 4-day continuous infusion of cisplatin (25 mg/m2/day). All patients received ondansetron 4 mg intravenously during 5-day administration of ESHAP. The primary endpoint was complete response (CR) for emesis, which was defined as absence of both emesis and rescue medications. Total control (TC) was defined as an absence of emetic episodes, including nausea and emesis, and complete protection (CP) was defined as an absence of emesis with addition of rescue antiemetics. Nausea and vomiting were assessed and graded daily by medical staff. RESULTS: Eighty-two patients were analyzed. Nausea and vomiting were generally well controlled, with the CR rates of emesis being 79% in the overall phase, 82% in the early phase (days 1-6), and 89% in the delayed phase (days 7-10). TC and CP were achieved in 51 patients (62%) and 77 patients (94%) in the overall phase. DISCUSSION: Most of the chemotherapy regimens for lymphoid malignancies include high-dose corticosteroid which may be also effective as antiemetics. Although NK1 receptor antagonist (NK1RA) is generally recommended for cisplatin-containing chemotherapy, it can interact with variety drugs. CONCLUSION: Although NK1RA is generally recommended for cisplatin-containing regimen, our results suggest that ondansetron effectively controlled emesis in patients receiving ESHAP therapy which includes high-dose corticosteroid.

A Person-Centered Approach to Symptom Assessment and Management for Children and Adolescents Receiving Cancer Treatment.

OBJECTIVES: Discuss the clinical assessment and management of symptoms for children and adolescents receiving treatment for cancer with attention to a person-centered approach to care. DATA SOURCES: Review of currently published literature and guidelines pertaining to symptom assessment and management for children and adolescents receiving treatment for cancer. CONCLUSION: Symptoms such as pain, nausea, and fatigue are commonly reported by children and adolescents receiving cancer treatment and are associated with greater symptom burden. Symptom assessment should be tailored to the child or adolescent and include the child's or adolescent's preference for reporting symptoms and attention to the symptoms that are of greatest priority. Evidence-based guidelines for the management of symptoms, including pain and nausea, are available to guide symptom management interventions and should be tailored to provide person-centered care. IMPLICATIONS FOR NURSING PRACTICE: Nurses can lead efforts through clinical practice and research initiatives to advance person-centered symptom care for children and adolescents with cancer on a global level. Priorities for future work to advance person-centered symptom assessment and management include (1) identification of best practices for symptom assessment, (2) attention to social determinants of health and their subsequent influence on symptom outcomes, (3) compilation of evidence for management of less commonly reported symptoms, and (4) implementation of published clinical guidelines for symptom management in practice settings.

The preferences of women with ovarian cancer for oral versus intravenous recurrence regimens.

OBJECTIVE: To assess preferences of women with ovarian cancer regarding features of available anti-cancer regimens for platinum-resistant, biomarker-positive disease, with an emphasis on oral PARP inhibitor and standard intravenous (IV) chemotherapy regimens. METHODS: A discrete-choice-experiment preferences survey was designed, tested, and administered to women with ovarian cancer, with 11 pairs of treatment profiles defined using seven attributes (levels/ranges): regimen (oral daily, IV weekly, IV monthly); probability of progression-free (PFS) at 6 months (40%-60%); probability of PFS at 2 years (10%-20%); nausea (none, moderate); peripheral neuropathy (none, mild, moderate); memory problems (none, mild); and total out-of-pocket cost ($0 to $10,000). RESULTS: Of 123 participants, 38% had experienced recurrence, 25% were currently receiving chemotherapy, and 18% were currently taking a PARP inhibitor. Given attributes and levels, the relative importance weights (sum 100) were: 2-year PFS, 28; cost, 27; 6-month PFS, 19; neuropathy,14; memory problems, nausea, and regimen, all ≤5. To accept moderate neuropathy, participants required a 49% (versus 40%) chance of PFS at 6 months or 14% (versus 10%) chance at 2 years. Given a 3-way choice where PFS and cost were equal, 49% preferred a monthly IV regimen causing mild memory problems, 47% preferred an oral regimen causing moderate nausea, and 4% preferred a weekly IV regimen causing mild memory and mild neuropathy. CONCLUSIONS: These findings challenge the assumption that oral anti-cancer therapies are universally preferred by patients and demonstrate that there is no "one size fits all" regimen that is preferable to women with ovarian cancer when considering recurrence treatment regimens.

Comparison of Nausea and Vomiting Associated With Amino Acid Formulations Coinfused With Peptide Receptor Radionuclide Therapy: Commercial Parenteral Nutrition Formulas Versus Compounded Arginine/Lysine.

OBJECTIVES: Positively charged amino acids (AA) such as arginine/lysine are coinfused with radiolabeled somatostatin analogs to reduce rates of nephrotoxicity. In the phase 3 NETTER-1 trial, commercial AA formulations were used in association with 177Lu-DOTA-0-Tyr3-Octreotate (DOTATATE). These formulations were also used in an early-access program (EAP) before regulatory approval of 177Lu-DOTATATE. Our program transitioned to compounded l-arginine 2.5%/l-lysine 2.5% in 0.9% NaCl after commercial approval of 177Lu-DOTATATE. We sought to compare rates of nausea/vomiting with arginine/lysine versus commercial parenteral AA formulations. METHODS: Rates of nausea/vomiting of all 20 EAP patients who received commercial AAs (15% Clinisol) were compared with the first 29 patients to receive 177Lu-DOTATATE after commercial approval and coinfused with arginine/lysine. Other parameters reviewed included infusion rates, need for PRN nausea medications, and other toxicities. RESULTS: Seventeen percent of patients who received compounded arginine/lysine experienced nausea, compared with 100% of patients in the EAP group (P < 0.0001). Infusion-related reactions occurred in 3% of the arginine/lysine cohort versus 35% in the EAP group. Infusion durations were substantially shorter in the arginine/lysine cohort (reduced by 61%). CONCLUSIONS: Coinfusions of arginine/lysine with radiolabeled somatostatin analogs result in substantially lower rates of nausea/vomiting compared with commercial AA formulations designed for parenteral nutrition.

[Update nausea and vomiting amongst the elderly]. / Update Übelkeit und Erbrechen in der Geriatrie.

Nausea (like vomiting) is a symptom and not an independent disease pattern. This makes it difficult to give an accurate number of the incidences in the elderly population. Approximately every 2nd to 3rd elderly person is affected.There are many possible causes of nausea (cerebrally caused, cerebrally controlled or caused by gastrointestinal disease). The physiological aging of the gastrointestinal tract on its own does not cause nausea.The diagnosis is based on a detailed medical history and an in-depth physical examination. Further diagnostic steps have to be customized to each patient. An official guidelines for diagnostics is not established.Initially the therapy aims to treat the cause (underlying disease or polypharmacy). Symptom-oriented medication should only be considered as secondary meassure. However, numerous possible drugs are inadequate for elderly people.

Antiemetics improve the tolerance of polyethylene glycol for colonoscopy preparation: A randomized clinical trial.

BACKGROUND: Bowel preparation is essential to the success of colonoscopy. However, many patients cannot finish the preparation due to nausea and vomiting when taking polyethylene glycol (PEG). Dopamine-2 receptor antagonists, such as domperidone and sulpiride, are classical antiemetic drugs. This study aimed to explore the effect of domperidone and sulpiride on reducing the discomforts associated with PEG. METHODS: Patients scheduled for colonoscopy were enrolled and randomly allocated into 3 groups. Patients in the domperidone group (Dom group) or sulpiride group (Sul group) took 2 doses of domperidone or sulpiride before PEG. Patients in the control group (Con group) followed the regular routine of PEG. Discomforts during bowel preparation and the quality of bowel preparation were assessed. RESULTS: A total of 306 patients were enrolled. The participants in the Dom group and Sul group completed PEG better and had fewer abdominal discomforts than those in the Con group. The severity of nausea and abdominal fullness was lower in the Dom group and Sul group. The quality of bowel preparation was better in the Dom group and Sul group than Con group. CONCLUSIONS: Domperidone and sulpiride could reduce the PEG-related discomfort and improve the quality of bowel preparation. This method may be a promising way to improve the satisfaction of bowel preparation for both patients and endoscopists.

Frequency, severity, and impact on daily life of delayed and intercycle chemotherapy-induced nausea, vomiting, and retching.

INTRODUCTION: Chemotherapy-induced nausea, vomiting, and retching (CINVR) remains a common side effect of treatment. Most previous studies have focused on vomiting control; nausea and retching have been less explored. This study aimed at describing the incidence, severity, and impact on daily life (IDL) of CINVR in the acute (0-24 hours), delayed (>24-120 hours), and overall (0-120 hours) postchemotherapy periods and beyond 120 hours (until next chemotherapy administration); and the pharmacologic and nonpharmacologic strategies adopted by patients to relieve symptoms. METHODS: This was a single-center, cross-sectional study of 60 patients undergoing chemotherapy. Participants reported the frequency, severity, and IDL of CINVR from the day of chemotherapy administration up to 120 hours thereafter and nausea and vomiting that occurred beyond 120 hours, as well as pharmacologic and nonpharmacologic remedies used. RESULTS: Forty-seven (78.3%, 95% confidence interval [CI] 66.4-86.9), 37 (61.7%, 95% CI 49.0-72.9), and 35 (58.3%, 95% CI 45.7-69.9) patients reported no nausea (Numeric Rating Scale ⩽1), vomiting, or retching in the acute, delayed, and overall periods, respectively. Nausea was more frequent, more severe, and had a greater IDL than did vomiting and retching across the overall observation period; beyond 120 hours, 11 (18.3%, 95% CI 10.6-29.9) patients reported nausea and none reported vomiting, with a median IDL of 1/10 (interquartile range: 0.75-5.00; 95% CI 0-7.6). Metoclopramide (n = 57 administrations), dexamethasone (n = 28), eating small servings of food (n = 13), and aloe (n = 11) were the most commonly used rescue therapies. CONCLUSIONS: Future studies should set hard outcomes, such as the absence of any symptoms, as a primary end point, and these should be assessed across and beyond the 120-hour period.

A pilot study of the effect of a home-based multimodal symptom-management program in children and adolescents undergoing chemotherapy.

BACKGROUND: Prevalent symptoms that affect children and adolescents throughout the process of cancer diagnosis and treatment include nausea and vomiting, fatigue, pain, mucositis, and anxiety. AIM: To examine the effect of a home-based multimodal symptom-management program for alleviation of nausea and vomiting, fatigue, pain, mucositis, and anxiety in children and adolescents undergoing chemotherapy for hematological malignancies or solid tumors. METHODS: In an exploratory pilot randomized study with qualitative interview, patients between 10 and 18 years of age were randomly assigned to either the symptom-management program plus usual care (intervention group) or usual care (control group). The program consisted of multiple nonpharmacological interventional components. The targeted symptoms were measured at baseline (after diagnosis), at the first 2 weeks of each cycle of chemotherapy, and at 6 months after baseline, using the Memorial Symptom Assessment Scale 10-18 and the State Anxiety Scale for Children. RESULTS: Fifty children (31 boys; mean age, 13.7 years) were randomized either to the intervention group or the control group (25 each) and underwent baseline assessment. A comparison between the groups showed that the intervention group had a significant less fatigue over time (P < .05). However, no differences were found with respect to nausea and vomiting, pain, mucositis, and anxiety between groups. Both children and parents reported a positive experience with the symptom-management program. CONCLUSION: The home-based symptom-management program may have helped to reduce fatigue in children and adolescents undergoing chemotherapy. In addition, qualitative data support the importance of improving children and parents' knowledge, coping skills, and psychological preparation for symptoms associated with chemotherapy.

The Management of Nausea and Vomiting Not Related to Anticancer Therapy in Patients with Cancer.

OPINION STATEMENT: In cancer patients, the management of nausea and vomiting that is not directly related to treatment is challenging. Much current practice is based on expert opinion and anecdote. Fortunately, over recent years, a number of quality trials have been undertaken to strengthen the evidence base that guides the care of our patients with these distressing symptoms. Much is still unknown however. In this article, we present the latest literature that addresses some of the outstanding issues.

Acute Benign Paroxysmal Positional Vertigo After Endothelial Keratoplasty-A Unique Cause of Postoperative Nausea and Headache.

PURPOSE: To describe a case of new-onset benign paroxysmal positional vertigo (BPPV) after uncomplicated Descemet stripping automated endothelial keratoplasty. METHODS: Case report and review of literature. RESULTS: A 61-year-old woman with a history of steroid-induced glaucoma and penetrating keratoplasty for Fuchs endothelial dystrophy, and no history of BPPV or other vertigo, underwent Descemet stripping automated endothelial keratoplasty for penetrating keratoplasty graft failure. On the third postoperative day, she developed acute spinning vertigo, nausea, and headache on sitting up after 3 days of strict supine positioning. Her ophthalmic examination was benign, with no evidence of a pupillary block, and she was diagnosed by an otologist with BPPV. Her symptoms resolved after 1 week without further intervention. CONCLUSIONS: BPPV is a benign but rare complication of nonotologic surgery and has not been previously reported with ophthalmic surgery. The overlap in symptomatology between BPPV and other serious and potentially vision-threatening causes of postoperative nausea and headache, such as pupillary block glaucoma, makes this a relevant etiology to consider in the spectrum of postendothelial keratoplasty complications.

Validation of the caregiver Pediatric Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events measure.

BACKGROUND: Despite improvements in survival rates, cancer treatments have significant side effects that affect the quality of life of children and their families. When an ill child cannot self-report symptoms (eg, he or she is too ill), caregiver (parent) reporting becomes critical. This study evaluates the validity and reliability of the caregiver-reported Pediatric Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE [Caregiver]) measure. METHODS: A diverse sample of caregivers with children receiving treatment at 9 oncology centers completed the Ped-PRO-CTCAE [Caregiver] measure, the Patient-Reported Outcomes Measurement Information System® (PROMIS® ) Parent Proxy measures, the Lansky Play-Performance Scale (PPS), medication use questions, and Global Impressions of Change (GIC). Construct validity (including convergent, discriminant, and known groups validity and responsiveness over time) and reliability (stability) were examined. RESULTS: A majority of the 473 caregivers were female (85%), non-Hispanic White (61%), and married (75%). Symptoms assessed with the Ped-PRO-CTCAE [Caregiver] and PROMIS Parent Proxy measures were strongly correlated (e.g., r for pain = 0.78; r for fatigue = 0.78; and r for depression = 0.83). Most of the Ped-PRO-CTCAE [Caregiver] item mean scores distinguished among PPS function levels and between children who did take medications for symptom control and children who did not. Changes in Ped-PRO-CTCAE [Caregiver] item mean scores were responsive to GIC over time. Test-retest evaluation found moderate to high agreement (57.8%-93.3%) over time. CONCLUSIONS: This study found strong evidence for the convergent and discriminant validity, known groups validity, responsiveness, and stability of the Ped-PRO-CTCAE [Caregiver] measure in a large and diverse sample of caregivers. The caregiver perspective provides a valuable and unique insight into the experiences of children and adolescents undergoing cancer treatment. LAY SUMMARY: Despite advances in cancer treatments, children and adolescents continue to suffer from treatment side effects, including pain, nausea, fatigue, and emotional distress, that can adversely affect quality of life for children and their families. Although it is best for children to report how they are feeling, there are times when a child may be too young or too ill to self-report. This study provides critical evidence for a new type of questionnaire that allows the caregiver or parent to report accurately what the child is experiencing. This measure can be used to improve adverse event reporting and child cancer care.

Elevated serum substance P level as a predictive marker for moderately emetogenic chemotherapy-induced nausea and vomiting: A prospective cohort study.

Chemotherapy-induced nausea and vomiting (CINV) is an unbearable side effect. Identifying high emetic risk patients and providing more active antiemetics strategies are mandatory to improve the tolerability of chemotherapy. In this prospective cohort study, leptin, ghrelin, and substance P were measured at baseline, day 3, and day 14 during the first cycle of chemotherapy. Nausea and vomiting were measured each day for the first 4 days of the first cycle of chemotherapy. Eighty-two patients were enrolled. Colorectal cancer (61%) and gastric cancer (35.4%) were common cancer types. All patients received moderate emetic risk chemotherapy. Forty-five (54.9%) patients had nausea, and 15 (18.3%) patients experienced vomiting. In univariate analysis, a higher level of baseline substance P, which is a target of NK1-RA (Neurokinin 1 receptor antagonist), was a significant predictive marker for chemotherapy-induced nausea [odds ratio (OR): 2.6, 95% confidence interval (CI): 1.02-6.62, p = 0.046]. Regarding chemotherapy-induced vomiting, patients with higher levels of substance P had a greater chance of vomiting [OR: 1.72, 95% CI: 0.49-5.99, p = 0.395] than those with lower levels of substance P. In patients receiving moderate emetic risk chemotherapy, active antiemetics, including NK1-RA, could be considered for those with high levels of substance P.
