Review
Pupillary examination has fundamental diagnostic and prognostic values in clinical practice. However, pupillary assessment was relied until present on manual, qualitative, examination, using manual flash penlights or lamps. Quantitative examination with the use of automated infrared video-pupillometers allows an objective assessment of several pupillary parameters and may be superior to manual subjective examination. The potential for quantitative pupillometry is multiple in the setting of critical care, for the monitoring and detection of secondary cerebral insults and to assess brainstem dysfunction and early coma outcome prognostication, and in the intra-operative anesthesiology setting, to assess analgesia and opioid requirement. Here, we describe the pupillometry technique and review recent critical care and anesthesiology studies that demonstrate the value and potential clinical utility of quantitative pupillometry as neuromonitoring bedside modality.

Review
Uncontrolled chemotherapy-induced nausea and vomiting can reduce patients' quality of life and may result in premature discontinuation of chemotherapy. Although nausea and vomiting are commonly grouped together, research has shown that antiemetics are clinically effective against chemotherapy-induced vomiting (CIV) but less so against chemotherapy-induced nausea (CIN). Nausea remains a problem for up to 68% of patients who are prescribed guideline-consistent antiemetics. Despite the high prevalence of CIN, relatively little is known regarding its etiology independent of CIV. This review summarizes a metagenomics approach to the study and treatment of CIN with the goal of encouraging future research. Metagenomics focuses on genetic risk factors and encompasses both human (ie, host) and gut microbial genetic variation. Little work to date has focused on metagenomics as a putative biological mechanism of CIN. Metagenomics has the potential to be a powerful tool in advancing scientific understanding of CIN by identifying new biological pathways and intervention targets. The investigation of metagenomics in the context of well-established demographic, clinical, and patient-reported risk factors may help to identify patients at risk and facilitate the prevention and management of CIN.

Review
BACKGROUND
Incidence rates of colorectal cancer (CRC) are increasing among adults born in and after the 1960s, implicating pregnancy-related exposures introduced at that time as risk factors. Dicyclomine, an antispasmodic used to treat irritable bowel syndrome, was initially included in Bendectin (comprising doxylamine, pyridoxine, and dicyclomine), an antiemetic prescribed during pregnancy in the 1960s.
METHODS
We estimated the association between in utero exposure to Bendectin and risk of CRC in offspring of the Child Health and Development Studies, a multigenerational cohort that enrolled pregnant women in Oakland, CA, between 1959 and 1966 (n = 14 507 mothers and 18 751 liveborn offspring). We reviewed prescribed medications from mothers' medical records to identify those who received Bendectin during pregnancy. Diagnoses of CRC in adult (aged ≥18 years) offspring were ascertained by linkage with the California Cancer Registry. Cox proportional hazards models were used to estimate adjusted hazard ratios, with follow-up accrued from birth through cancer diagnosis, death, or last contact.
RESULTS
Approximately 5% of offspring (n = 1014) were exposed in utero to Bendectin. Risk of CRC was higher in offspring exposed in utero (adjusted hazard ratio = 3.38, 95% confidence interval [CI] = 1.69 to 6.77) compared with unexposed offspring. Incidence rates of CRC were 30.8 (95% CI = 15.9 to 53.7) and 10.1 (95% CI = 7.9 to 12.8) per 100 000 in offspring exposed to Bendectin and unexposed, respectively.
CONCLUSIONS
Higher risk of CRC in offspring exposed in utero may be driven by dicyclomine contained in the 3-part formulation of Bendectin used during the 1960s. Experimental studies are needed to clarify these findings and identify mechanisms of risk.

Review
Common treatment methods for malignant tumors include surgery, chemotherapy, radiotherapy, immunotherapy, targeted therapy, etc., among which chemotherapy plays an important role. However, chemotherapy brings corresponding side effects while killing tumor cells, and nausea and vomiting are the most common adverse reactions induced by chemotherapy. It not only affects the patient's appetite, resulting in malnutrition and electrolyte disturbances, but also reduces the patient's compliance with treatment, which further aggravates the disease. Thus, it is important to quickly prevent and cure nausea and vomiting induced by chemotherapy (CINV). In addition, with the continuous development of medicine, more and more antiemetic drugs have been developed. At present, the most common antiemetic agents for chemotherapy-induced nausea and vomiting are NK-1R antagonists, 5-HT3R antagonists, and dexamethasone. Surprisingly, olanzapine, often used as a psychotropic drug, has been found to be an effective antiemetic and is similar to other regimens on the safety of medicine. However, although there are numerous studies on the antiemetic effects of olanzapine, its comprehensive application remains unclear. Therefore, this review will elaborate the antiemetic effect of olanzapine in terms of the antiemetic mechanism and the safety, economic cost, dose, administration time, and drug delivery aspects.

Randomized Controlled Trial
Veliparib with frontline chemotherapy and as maintenance in Japanese women with ovarian cancer: a subanalysis of efficacy, safety, and antiemetic use in the phase 3 VELIA trial.
BACKGROUND
The phase 3 VELIA trial evaluated veliparib with carboplatin/paclitaxel and as maintenance in patients with high-grade serous ovarian carcinoma.
METHODS
Patients with previously untreated stage III-IV high-grade serous ovarian carcinoma were randomized 1:1:1 to control (placebo with carboplatin/paclitaxel and placebo maintenance), veliparib-combination-only (veliparib with carboplatin/paclitaxel and placebo maintenance), or veliparib-throughout (veliparib with carboplatin/paclitaxel and veliparib maintenance). Randomization stratification factors included geographic region (Japan versus North America or rest of the world). Primary end point was investigator-assessed median progression-free survival. Efficacy, safety, and pharmacokinetics were evaluated in a subgroup of Japanese patients.
RESULTS
Seventy-eight Japanese patients were randomized to control (n = 23), veliparib-combination-only (n = 30), and veliparib-throughout (n = 25) arms. In the Japanese subgroup, median progression-free survival for veliparib-throughout versus control was 27.4 and 19.1 months (hazard ratio, 0.46; 95% confidence interval, 0.18-1.16; p = 0.1 [not significant]). In the veliparib-throughout arm, grade 3/4 leukopenia, neutropenia, and thrombocytopenia rates were higher for Japanese (32%/88%/32%) versus non-Japanese (17%/56%/28%) patients. Grade 3/4 anemia rates were higher in non-Japanese (65%) versus Japanese (48%) patients. Early introduction of olanzapine during veliparib monotherapy maintenance phase may help prevent premature discontinuation of veliparib, via its potent antiemetic efficacy.
CONCLUSIONS
Median progression-free survival was numerically longer in Japanese patients in the veliparib-throughout versus control arm, consistent with results in the overall study population. Pharmacokinetics were comparable between Japanese and non-Japanese patients. Data for the subgroup of Japanese patients were not powered to show statistical significance but to guide further investigation.

Randomized Controlled Trial
Comparison of postoperative nausea and vomiting between Remimazolam and Propofol in Patients undergoing oral and maxillofacial surgery: a prospective Randomized Controlled Trial.
BACKGROUND
Remimazolam is a recently approved, ultra-short-acting benzodiazepine. However, few studies have investigated remimazolam in relation to postoperative nausea and vomiting (PONV). This study aimed to compare the effects of remimazolam and propofol on PONV in patients undergoing oral and maxillofacial surgery.
METHODS
Patients (n = 206) aged 19-65 years who were scheduled for oral and maxillofacial surgery were randomized into two groups, the remimazolam (R) and propofol group (P). In the R group (n = 94), remimazolam was used to induce anesthesia at 12 mg/kg/h and to maintain anesthesia at 1-2 mg/kg/h. In the P group (n = 95), anesthesia was induced and maintained with propofol (target effect-site concentration: 3-5 µg/ml). In both groups, remifentanil was administered at a target effect-site concentration of 2.5-4 ng/ml. The primary outcome was the overall incidence of PONV during the first 24 h after surgery. Secondary outcomes included the severity of nausea, use of rescue antiemetics, severity of postoperative pain, use of rescue analgesia, and quality of recovery.
RESULTS
The incidence of PONV during the first 24 h after surgery was 11.7% and 10.5% in the R group and P group, respectively, and there was no significant difference in the severity of nausea (P > 0.05). Ten patients in the R group and ten patients in the P group required rescue antiemetics during the first 24 h after surgery (P = 0.98). No inter-group differences were observed in terms of postoperative pain score, use of rescue analgesia, and quality of recovery (P > 0.05).
CONCLUSIONS
In this study, remimazolam did not increase the incidence and severity of PONV compared with propofol.

Review
Chemotherapy-induced nausea and vomiting (CINV) is a serious side effect of chemotherapy that negatively impacts the quality of life of oncological patients and is associated with the emetogenic risk specific to administered chemotherapy. Current practice guidelines on the use of antiemetics in CINV include the option of adding olanzapine to antiemetic regimens in the management of adult CINV. The use of olanzapine in pediatric CINV has been restricted to children with poor CINV control. Research on the use of olanzapine in pediatric CINV has been limited. The aim of this review was to evaluate current evidence on the effective and safe antiemetic use of olanzapine in pediatric CINV of any type following chemotherapy of any emetogenicity. Ovid MEDLINE, Embase, CENTRAL databases were searched for any literature on the use of olanzapine in pediatric CINV published from 2015 to 2022. Studies that reported on the olanzapine-containing antiemetic regimen in peadiatric CINV control specifically were included. Search restrictions were placed on research published in English. The search generated 43 records that were assessed for eligibility. Out of 10 identified eligible studies a third were RCT. Findings of this review suggest that adding olanzapine to antiemetic regimen in pediatric CINV control is a worthwhile consideration. Further research is needed to establish the efficacy and safety of antiemetic olanzapine use in pediatric CINV.

BACKGROUND
Nausea and vomiting are common and distressing side effects of tumor therapy. Despite prophylaxis, 40-50% of patients suffer from nausea, and 20-30% from vomiting. Antiemetic prophylaxis and treatment are therefore of great importance for improving patients' quality of life and preventing sequelae such as tumor cachexia.
METHODS
The recommendations presented here are based on international and national guidelines, updated with publications retrieved by a selective search in the PubMed and Cochrane Library databases, with special attention to randomized controlled trials and meta-analyses that have appeared in the past 5 years since the German clinical practice guideline on supportive therapy was published.
RESULTS
Risk-adjusted prevention and treatment is based on the identification of treatment-related and patient-specific risk factors, including female sex and younger age. Parenteral tumor therapy is divided into four risk classes (minimal, low, moderate, high), and oral tumor therapy into two (minimal/low, moderate/high). In radiotherapy, the radiation field is of decisive importance. The antiemetic drugs most commonly used are 5-HT3-RA, NK1-RA, and dexamethasone; olanzapine has proven beneficial as an add-on or rescue drug. The use of steroids in patients being treated with drug combinations including checkpoint inhibitors is discussed controversially because of the potentially reduced therapeutic response. Benzodiazepines, dimenhydrinate, and cannabinoids can be used as backup antiemetics. Acupuncture/acupressure, ginger, and progressive muscle relaxation are pos - sible alternative methods.
CONCLUSION
Detailed, effective, risk profile-adapted algorithms for the prevention and treatment of nausea and vomiting are now available for patients undergoing classic chemotherapy regimens or combined radiotherapy and chemotherapy. Optimal symptom control for patients undergoing oral tumor therapy over multiple days in the outpatient setting remains a challenge.

Randomized Controlled Trial
BACKGROUND
Postoperative nausea and vomiting (PONV) is a major problem after surgery. Even with double prophylactic therapy including dexamethasone and a 5-hydroxytryptamine-3 receptor antagonist, the incidence is still high in many at-risk patients. Fosaprepitant, a neurokinin-1 receptor antagonist, is an effective antiemetic, but its efficacy and safety in combination antiemetic therapy for preventing PONV remain unclear.
METHODS
In this randomised, controlled, double-blind trial, 1154 participants at high risk of PONV and undergoing laparoscopic gastrointestinal surgery were randomly assigned to either a fosaprepitant group (n=577) receiving fosaprepitant 150 mg i.v. dissolved in 0.9% saline 150 ml, or a placebo group (n=577) receiving 0.9% saline 150 ml before anaesthesia induction. Dexamethasone 5 mg i.v. and palonosetron 0.075 i.v. mg were each administered in both groups. The primary outcome was the incidence of PONV (defined as nausea, retching, or vomiting) during the first 24 postoperative hours.
RESULTS
The incidence of PONV during the first 24 postoperative hours was lower in the fosaprepitant group (32.4% vs 48.7%; adjusted risk difference -16.9% [95% confidence interval: -22.4 to -11.4%]; adjusted risk ratio 0.65 [95% CI: 0.57 to 0.76]; P<0.001). There were no differences in severe adverse events between groups, but the incidence of intraoperative hypotension was higher (38.0% vs 31.7%, P=0.026) and intraoperative hypertension (40.6% vs 49.2%, P=0.003) was lower in the fosaprepitant group.
CONCLUSIONS
Fosaprepitant added to dexamethasone and palonosetron reduced the incidence of PONV in patients at high risk of PONV undergoing laparoscopic gastrointestinal surgery. Notably, it increased the incidence of intraoperative hypotension.

OBJECTIVE
As a result of recent legislative changes allowing for increased access to marijuana products, there have been increasing rates of cannabis abuse among adolescents and subsequent diagnoses of cannabinoid hyperemesis syndrome (CHS). Most available literature on this syndrome exists within the adult population and describes benzodiazepines, haloperidol, and topical capsaicin as potentially efficacious in the management of CHS. The objectives of this study were to identify antiemetics and compare their efficacy and safety in the management of pediatric CHS.
METHODS
A retrospective review of Penn State Children's Hospital electronic health record was performed to identify patients 18 years or younger who had an emergency department or inpatient encounter, a cannabis hyperemesis-related diagnosis code, and met diagnostic criteria for CHS. Antiemetic efficacy was determined using subjective patient perception of nausea and objective documentation of vomiting. Benzodiazepines, haloperidol, and topical capsaicin were classified as nontraditional antiemetics, whereas all other antiemetics were classified as traditional.
RESULTS
Nontraditional antiemetic medications appeared to be more effective in resolving patient symptoms compared with traditional antiemetics. Analysis of all ordered antiemetics demonstrated a gap in partial or full symptom resolution between nontraditional and traditional agents. Reported adverse effects were minimal.
CONCLUSIONS
Cannabinoid hyperemesis syndrome is an underrecognized and underdiagnosed condition characterized by cyclic vomiting related to chronic cannabis use. Abstinence from cannabis remains the most effective approach to mitigating morbidity associated with CHS. Medications such as lorazepam or droperidol may have benefit in managing toxidrome symptoms. Traditional antiemetic prescribing remains a key barrier to effective management of pediatric CHS.
