Randomized Placebo-Controlled Trial of Topical Capsaicin for Delayed Chemotherapy-Induced Nausea and Vomiting.

PURPOSE: We examined the efficacy of topical capsaicin in reducing delayed chemotherapy-induced nausea and vomiting (CINV). METHODS: Adults on highly emetogenic chemotherapy regimens applied 2 g of capsaicin ointment (0.075%) or matching placebo four times a day to the abdomen for 5 days in addition to standard antiemetic regimen in this blinded randomized controlled trial. Patients were monitored for nausea and vomiting in the immediate (day 1), delayed (days 2-5), and extended phases (days 2-15). Self-reported incidence and daily episodes of CINV were compared between the groups. Onset, severity, need for rescue antiemetics, cumulative vomiting episodes, and safety were also compared. RESULTS: In total, 160 patients were enrolled. The final modified intention-to-treat population included 75 patients each in the capsaicin and placebo groups. Fewer patients experienced nausea (36.0% [n = 27] v 53.3% [n = 40]; P = .033) and vomiting (28.0% [n = 21] v 42.7% [n = 32]; P = .060) in the capsaicin arm during the delayed phase. During the extended phase, there was a significantly lower incidence of nausea (44% v 64.0%; P = .014) in the capsaicin arm. No difference in nausea (26.7% v 25.3%) or vomiting (22.7% v 18.7%) was evident in the immediate phase. The average daily episodes of nausea and vomiting were significantly fewer in the capsaicin arm during the delayed and extended phases. With capsaicin, no grade 3 nausea (9.3% v 0.0%; P = .007) was observed, and the time to first nausea and vomiting was significantly prolonged. There were no differences between the groups with respect to rescue antiemetics, unscheduled hospital visits, and adverse events. CONCLUSION: Topical capsaicin reduced the incidence of nausea and the average number of vomiting episodes during delayed and extended phases without increasing adverse effects.

Latent class analysis of migraine associated vestibular-auditory symptoms.

OBJECTIVE: This study aimed to identify the potential subgroups of migraines based on the patterns of migraine associated symptoms, vestibular and auditory symptoms using latent class analysis and to explore their characteristics. METHOD: A total of 555 patients with migraine participated in the study. Symptoms such as nausea, vomiting, photophobia, phonophobia, osmophobia, visual symptoms, vestibular symptoms (dizziness, vertigo), and auditory symptoms (tinnitus, hearing loss, aural fullness) were assessed. Latent class analysis was performed to identify subgroups of migraines. Covariates such as gender, age of migraine onset, frequency of migraine attacks per month, and family history were also considered. RESULTS: The analysis revealed four latent classes: the Prominent Vestibular; Prominent Nausea; Presenting Symptoms but not prominent or dominant; and Sensory Hypersensitivity groups. Various covariates, such as gender, age of migraine onset, and frequency of migraine attacks, demonstrated significant differences among the four groups. The Sensory Hypersensitivity group showed the presence of multiple sensory symptoms, earlier age of migraine onset, and higher proportion of females. The Prominent Vestibular group had the highest probability of dizziness or vertigo but lacked the presence of auditory symptoms. The Prominent Nausea group exhibited prominent nausea. The Presenting Symptoms but not prominent or dominant group comprised individuals with the highest migraine attacks per month and proportion of chronic migraine. CONCLUSION: This study identifies four subgroups of migraines based on the patterns of symptoms. The findings suggest potential different but overlapped mechanisms behind the vestibular and auditory symptoms of migraine. Considering the different patterns of migraine-related symptoms may provide deeper insights for patients' prognosis and clinical decision-making.

The emerging emetogenicity of trifluridine/tipiracil (TAS­102) from patient self-reporting: a multicenter, prospective, observational study.

BACKGROUND: Trifluridine/tipiracil (TAS-102) is an oral anticancer drug with adequate efficacy in unresectable colorectal cancer, but frequently also induces chemotherapy-induced nausea and vomiting (CINV). To investigate the occurrence of CINV and antiemetic therapy in patients with colorectal cancer treated with TAS-102 (JASCC-CINV 2001). METHODS: We conducted a multicenter, prospective, observational study in patients with colorectal cancer who received TAS-102 without dose reduction for the first time. Primary endpoint was the incidence of vomiting during the overall period. Secondary endpoints were the incidence of nausea, significant nausea, anorexia, other adverse events (constipation, diarrhea, insomnia, fatigue, dysgeusia) and patient satisfaction. Patient diaries were used for primary and secondary endpoints. All adverse events were subjectively assessed using PRO-CTCAE ver 1.0. and CTCAE ver 5.0. RESULTS: Data from 100 of the 119 enrolled patients were analyzed. The incidence of vomiting, nausea, and significant nausea was 13%, 67%, and 36%, respectively. The incidence of vomiting in patients with and without prophylactic antiemetic therapy were 20.8% and 10.5%, respectively. Prophylactic antiemetics were given to 24% of patients, of whom 70% received D2 antagonists. Multivariate Cox proportional hazards analysis showed that experience of CINV in previous treatment tended to be associated with vomiting (hazard ratio [HR]: 7.13, 95% confidence interval [CI]: 0.87-58.5, P = 0.07), whereas prophylactic antiemetic administration was not (HR: 1.61, 95 CI: 0.50-5.21, P = 0.43). With regard to patient satisfaction, the proportion of patients who were "very satisfied," "satisfied," "slightly satisfied" or "somewhat satisfied" was 81.8%. CONCLUSIONS: The low incidence of vomiting and high patient satisfaction suggest that TAS-102 does not require the use of uniform prophylactic antiemetic treatments. However, patients with the experience of CINV in previous treatment might require prophylactic antiemetic treatment.

Clinical presentation and management of methanol poisoning outbreaks in Riyadh, Saudi Arabia: a retrospective analysis.

BACKGROUND: Acute methanol intoxication, whether unintentional or deliberate, necessitates prompt intervention to prevent severe morbidity and mortality. Homemade alcoholic beverages are a frequent source of such poisoning. This retrospective analysis examined two outbreaks of methanol intoxication in Saudi Arabia. It investigated the clinical presentation, implemented management strategies, and any lasting complications (sequelae) associated with these cases. The aim was to assess the potential impact of different treatment modalities and the timeliness of their initiation on patient outcomes. METHODS: This was a retrospective case series of methanol poisoning cases which presented to the adult emergency department (ED) at King Abdulaziz Medical City (KAMC) in Riyadh, Saudi Arabia. There were two separate outbreaks in the city, the first one was from September 1 to September 10, 2020 and the second one was from May 14 to May 20, 2021. Electronic charts were reviewed, and data were extracted to previously prepared data extraction sheets. RESULT: From the 22 patients who arrived in the ED alive, the most common complaints were nausea or vomiting followed by altered level of consciousness. About 9% from the patient were hypotensive, 36% were tachycardic, 41% were tachypneic and 4% were having SpO2 < 94%. Brain CT was abnormal in 6 patients. Vision impairment was the most common sequalae of methanol poisoning (7 out of 12 patients who were assessed by ophthalmologist, 58%). When the patients were divided based on severity (mild, moderate, severe), nausea or vomiting and loss of consciousness were the most common complaints among the moderate group while loss of consciousness predominated in the severe group. Two patients presented with low blood pressure and were in the sever group. The severe group had a mean Glasgow Coma Scale (GCS) of 8. Most of the patients in the severity groups underwent the same management apart from those who died or deposited. Eight patients in the severe group had to be intubated. CONCLUSION: This study demonstrates the multifaceted clinical presentation of methanol poisoning, culminating in a 17.4% mortality rate. Notably, our findings emphasize the critical role of prompt diagnosis and swift initiation of combined fomepizole therapy and hemodialysis in mitigating mortality and minimizing the potential for chronic visual sequelae associated with methanol poisoning.

Characteristics of nausea and its impact on health-related quality of life in cisplatin-treated patients receiving dexamethasone-sparing prophylaxis: an analysis of the LUNG-NEPA study.

PURPOSE: We investigated the intensity and duration of nausea as well as its impact on health-related quality of life among cisplatin-treated patients who participated in a study of dexamethasone (DEX)-sparing regimens based on NEPA (netupitant/palonosetron). METHODS: This retrospective analysis included chemo-naive patients from a trial evaluating non-inferiority of DEX on day 1 (DEX1 arm) combined with NEPA, compared with the same regimen with DEX administered on days 1-4 (DEX4; reference arm) following cisplatin (≥ 70 mg/m2) administration. Nausea intensity was self-rated using a four-point Likert scale. Extended nausea duration was considered ≥ 3 days within the 5 days post-chemotherapy. Patients completed the Functional Living Index-Emesis (FLIE) questionnaire on day 6. RESULTS: In the DEX1 arm, more patients (20/76) experienced acute nausea, influencing the outcome of delayed nausea (38/76). During days 1 to 5, 51.3% (39/76) and 39.5% (30/76) of patients experienced nausea in the DEX1 and DEX4 arms, respectively (P = 0.192). Of these, 43.6% and 60% reported moderate-to-severe nausea, respectively, in the DEX1 and DEX4 arms (P = 0.200), while 74.4% and 56.7% of patients experienced extended nausea duration (P = 0.122). Similar between-arm rates of nauseated patients reported an impact on daily life (79.5% vs. 70%; P = 0.408). In analyses stratified for antiemetic regimen, moderate-to-severe nausea or extended nausea duration was associated with an impact on daily life (P ≤ 0.001). CONCLUSION: Despite the higher incidence, there was no suggestion of any strong adverse effect of NEPA plus single-dose DEX on the characteristics of nausea as well as its impact on daily life in patients with cisplatin-induced nausea. Further prospective controlled study is warranted. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT04201769. Registration date: 17/12/2019.

Incidence of Radiation-induced Nausea and Vomiting: A Prospective Single-institution Pilot Study.

Radiation-induced nausea and vomiting (RINV) is a frequent adverse event that occurs in patients undergoing radiotherapy. However, research on RINV is underrepresented. This prospective single-institution exploratory pilot study investigated the incidence of RINV according to the irradiation site and observed the efficacy of symptomatic antiemetic treatment in controlling symptoms of RINV. The primary outcomes were the proportions of emesis-free days and nausea-free days. The secondary endpoints included the time to the first episode of RINV, frequency of vomiting, and severity of nausea, including its impact on eating habits and weight loss. Fifteen patients were enrolled in each group (minimal, low, and moderate emetogenic risk). All patients received greater than 20 Gy in five fractions. Evaluation was based on weekly questionnaires completed by patients during routine clinic visits. Nausea and vomiting occurred in 11 and 0 patients, respectively. Six of 15 patients in the minimal-risk group, 1 in the low-risk group, and 4 in the moderate-risk group experienced nausea. Although all 11 symptomatic patients were offered antiemetics, only 3 used them, who reported satisfactory control of nausea. The percentage of emesis-free days for all patients was 100% and the percentage of nausea-free days for the 11 patients who developed RINV was 38%. An unexpectedly high percentage of patients in the minimal-risk group experienced nausea; all had breast cancer. Future studies should investigate factors beyond the irradiation site, including the characteristics of the patient and the treatment, to better predict an individual's risk of RINV.

Comparison of nintedanib-induced gastrointestinal adverse events between patients with systemic sclerosis-associated interstitial lung disease and idiopathic interstitial pneumonias.

BACKGROUND: Gastrointestinal symptoms, such as diarrhea and nausea, are common adverse events associated with nintedanib. Systemic sclerosis is associated with a high prevalence of gastrointestinal symptoms that may increase with nintedanib administration. In clinical practice, we aimed to determine whether patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD) experience more adverse gastrointestinal events associated with nintedanib than patients with idiopathic interstitial pneumonias (IIPs). METHODS: We retrospectively examined the clinical records of patients with SSc-ILD and IIPs newly treated with nintedanib at Kumamoto University Hospital between January 2020 and September 2022 and compared adverse events. RESULTS: In total, 27 patients with SSc-ILD and 34 with IIPs were enrolled. No significant differences were observed in the duration of nintedanib treatment. The most frequent adverse event in both groups was diarrhea, which was more frequent in the SSc-ILD group (81.5 % vs. 61.8 %, p = 0.157). Nausea was significantly more frequent in the SSc-ILD group than in the IIPs group (37.0 % vs. 11.8 %, p = 0.031). The permanent discontinuation rate of nintedanib during the study period between the two groups was not different (40.7 % vs. 32.4 %, p = 0.595). However, the most common reasons for discontinuation varied. The most frequent reason in the SSc-ILD group was nausea, due to the progression of ILD in the IIPs group. CONCLUSIONS: Patients with SSc-ILD experienced significantly more nintedanib-induced nausea than those with IIPs. Gastrointestinal adverse events are often the reason for discontinuation of nintedanib in the SSc-ILD group, which requires better management of gastrointestinal symptoms.

Metabolites Associated With Uremic Symptoms in Patients With CKD: Findings From the Chronic Renal Insufficiency Cohort (CRIC) Study.

RATIONALE & OBJECTIVE: The toxins that contribute to uremic symptoms in patients with chronic kidney disease (CKD) are unknown. We sought to apply complementary statistical modeling approaches to data from untargeted plasma metabolomic profiling to identify solutes associated with uremic symptoms in patients with CKD. STUDY DESIGN: Cross-sectional. SETTING & PARTICIPANTS: 1,761 Chronic Renal Insufficiency Cohort (CRIC) participants with CKD not treated with dialysis. PREDICTORS: Measurement of 448 known plasma metabolites. OUTCOMES: The uremic symptoms of fatigue, anorexia, pruritus, nausea, paresthesia, and pain were assessed by single items on the Kidney Disease Quality of Life-36 instrument. ANALYTICAL APPROACH: Multivariable adjusted linear regression, least absolute shrinkage and selection operator linear regression, and random forest models were used to identify metabolites associated with symptom severity. After adjustment for multiple comparisons, metabolites selected in at least 2 of the 3 modeling approaches were deemed "overall significant." RESULTS: Participant mean estimated glomerular filtration rate was 43mL/min/1.73m2, with 44% self-identifying as female and 41% as non-Hispanic Black. The prevalence of uremic symptoms ranged from 22% to 55%. We identified 17 metabolites for which a higher level was associated with greater severity of at least one uremic symptom and 9 metabolites inversely associated with uremic symptom severity. Many of these metabolites exhibited at least a moderate correlation with estimated glomerular filtration rate (Pearson's r≥0.5), and some were also associated with the risk of developing kidney failure or death in multivariable adjusted Cox regression models. LIMITATIONS: Lack of a second independent cohort for external validation of our findings. CONCLUSIONS: Metabolomic profiling was used to identify multiple solutes associated with uremic symptoms in adults with CKD, but future validation and mechanistic studies are needed. PLAIN-LANGUAGE SUMMARY: Individuals living with chronic kidney disease (CKD) often experience symptoms related to CKD, traditionally called uremic symptoms. It is likely that CKD results in alterations in the levels of numerous circulating substances that, in turn, cause uremic symptoms; however, the identity of these solutes is not known. In this study, we used metabolomic profiling in patients with CKD to gain insights into the pathophysiology of uremic symptoms. We identified 26 metabolites whose levels were significantly associated with at least one of the symptoms of fatigue, anorexia, itchiness, nausea, paresthesia, and pain. The results of this study lay the groundwork for future research into the biological causes of symptoms in patients with CKD.

The safety of remimazolam versus propofol in gastroscopic sedation: a meta-analysis.

BACKGROUND: This meta-analysis was designed to compare the safety and efficiency of remimazolam with those of propofol in patients undergoing gastroscope sedation. METHODS: We searched PubMed, Cochrane Library, Embase, Ovid, Wanfang Database, China National Knowledge Infrastructure, SINOMED, and ClinicalTrials.gov for studies that reported on remimazolam versus propofol for gastroscope sedation from establishment to February 25, 2023. The sedative efficiency and the incidence of adverse events were assessed as outcomes. Version 2 of the Cochrane risk-of-bias assessment tool was used to assess the risk of bias. Review Manager 5.4 and STATA 17 were used to perform all statistical analyses. RESULTS: A total of 26 randomized controlled trials involving 3,641 patients were included in this meta-analysis. The results showed that remimazolam had a significantly lower incidence of respiratory depression (risk ratio [RR] = 0.40, 95% confidence interval [CI]: 0.28-0.57; p < 0.01, GRADE high), hypoxemia (RR = 0.34, 95% CI: 0.23-0.49; p < 0.01, GRADE high), bradycardia (RR = 0.34, 95% CI: 0.23-0.51; p < 0.01, GRADE high), dizziness (RR = 0.45, 95% CI: 0.31-0.65; p < 0.01, GRADE high), injection site pain (RR = 0.06, 95% CI: 0.03-0.13; p < 0.01, GRADE high), nausea or vomiting (RR = 0.79, 95% CI: 0.62-1.00; p = 0.05, GRADE moderate), and hypotension (RR = 0.36, 95% CI: 0.26-0.48; p < 0.01, GRADE low). CONCLUSIONS: Remimazolam can be used safely in gastroscopic sedation and reduces the incidence of respiratory depression, hypoxemia, bradycardia, injection site pain, and dizziness compared with propofol, and doesn't increase the incidence of nausea and vomiting.

Young-onset colorectal cancer: treatment-related nausea, vomiting and diarrhoea.

OBJECTIVES: Early-onset colorectal cancer (EO-CRC) incidence is increasing, raising a clinical challenge. Clinicians tend to treat EO-CRC patients with more intensive regimens despite the lack of survival benefits, based on an age-related bias. Limited evidence is available regarding treatment-related toxicities in this peculiar subset of patients. METHODS: We performed a literature search in MEDLINE/PubMed, EMBASE and Scopus, looking for reporting of nausea, vomiting and diarrhoea occurring in patients with EO-CRC, defined by age lower than 50 years old at initial diagnosis, while receiving anticancer treatment. RESULTS: 2318 records were screened and 9 full-text articles were considered eligible for inclusion for a total of 59 783 patients (of whom 8681 EO-CRC patients). We found nausea and vomiting occurring at higher incidence among EO-CRC compared with older patients, while no difference was reported as for diarrhoea. Peritoneal involvement, age younger than 40, female gender, suboptimal adherence to guidelines and oxaliplatin might represent potential risk factors for increased nausea and vomiting in patients with EO-CRC. CONCLUSION: EO-CRC patients experience more nausea and vomiting but equal or less diarrhoea compared with older patients. Adherence to clinical guidelines is recommended, and more data are warranted to assess if an enhanced antiemetic approach might be required, particularly in case of specific risk factors.

Analysis of Nausea and Vomiting Frequency Following Opioid Dose Escalation and Its Risk Factors: A Single-Center Retrospective Observational Study.

Background and Objective: Opioid-induced nausea and vomiting (OINV) is known to develop not only upon opioid introduction but also during opioid dose escalation, but the actual details are unclear. The aim of this study was to investigate the frequency of OINV in opioid dose escalation at a single center and to identify risk factors. Methods: A retrospective analysis of the medical records of hospitalized patients with cancer who underwent increased intake of oral oxycodone extended-release tablets at Komaki City Hospital between January 2016 and December 2019 was performed. Associations between the incidence of OINV and multiple factors were analyzed, including patient demographics, opioid daily dose, comorbidities, history of nausea after opioid introduction, and prophylactic antiemetic drugs. Results: Of the 132 patients analyzed, 56 (42.4%; grades 1 and 2, 36 and 20, respectively) developed opioid-induced nausea after opioid dose escalation, 26 (19.7%; grades 1 and 2, 19 and 7, respectively) developed opioid-induced vomiting, 58 (43.9%) had either opioid-induced nausea or vomiting. Thirty-five of 60 patients (55.0%) developed OINV among those who received prophylactic antiemetic drugs at opioid dose escalation. Performance status (≥2) (odds ratio [OR]: 2.36, 95% confidence interval [95% CI]: 1.15-4.84, p = 0.02) and history of nausea for opioid introduction (OR: 2.92, 95% CI: 1.20-7.10, p = 0.02) were detected as risk factors for the development of OINV. Conclusion: This study revealed a high incidence of OINV during opioid dose escalation, indicating that careful monitoring is required as at the time of opioid introduction. Further validation by a prospective study is required.

Comparison of the incidence of nausea and vomiting between linezolid and vancomycin using claims database: a retrospective cohort study.

BACKGROUND: Nausea and vomiting during linezolid therapy have been reported as part of safety analyses in clinical trials. We have previously examined the incidence of vomiting during linezolid therapy (18.1%). A previous study conducted at a single hospital showed low external validity. It is necessary to verify whether these results can be reproduced using generalizable data sources. AIM: To evaluate the incidence of nausea and vomiting during linezolid therapy compared with vancomycin using a Japanese claims database. METHOD: Patients administered linezolid or vancomycin were selected from the database between January 2005 and June 2017. The primary endpoint was the comparison of nausea and vomiting between the linezolid and vancomycin groups. We conducted propensity score matching (PSM) to adjust for patient characteristics. To assess risk factors for nausea and vomiting, logistic regression was conducted as the secondary endpoint. We defined nausea and vomiting as the first prescription of antiemetics during linezolid or vancomycin therapy as a surrogate endpoint. RESULTS: In total, 1215 patients were enrolled. After PSM, the number of patients in the linezolid and vancomycin groups was 241. Nausea and vomiting were observed in 11.2% and 5.0% of patients in the linezolid and vancomycin groups, respectively (p < 0.05). Linezolid administration was extracted as a risk factor for nausea and vomiting (odds ratio, 2.09; 95% confidence interval, 1.02-4.30). CONCLUSION: This study clarified the relationship between linezolid and nausea and vomiting using a Japanese claims database. Further studies are required to elucidate the unknown mechanisms of linezolid-induced nausea and vomiting.

Cannabis use in the United States and its impact on gastrointestinal health.

In recent years, the legalization and social acceptability of cannabis use have increased in the United States. Concurrently, the prevalence of cannabis use has continued to rise, and cannabis products have diversified. There are growing concerns regarding the health effects of regular and high-potency cannabis use, and new research has shed light on its potentially negative effects. Here, we review evidence of the gastrointestinal (GI) effects of cannabis and cannabinoids. Dysregulation of the endocannabinoid system might contribute to various GI disorders, including irritable bowel syndrome and cyclic vomiting syndrome, and endocannabinoids have been found to regulate visceral sensation, nausea, vomiting, and the gut microbiome. Cannabis has been shown to have antiemetic properties, and the US Food and Drug Administration has approved cannabis-based medications for treating chemotherapy-induced nausea and vomiting. Yet, chronic heavy cannabis use has been linked to recurrent episodes of severe nausea and intractable vomiting (cannabinoid hyperemesis syndrome). Given the considerable heterogeneity in the scientific literature, it is unclear if cannabinoid hyperemesis syndrome is truly a distinct entity or a subtype of cyclic vomiting that is unmasked by heavy cannabis use and the associated dysregulation of the endocannabinoid system. The changes in cannabis legalization, availability, and public risk perceptions have outpaced research in this area and there is a need for robust, prospective, large-scale studies to understand the effects of cannabis use on GI health.

Factor Analysis of Fatigue in the Early Stages of Cancer Chemotherapy.

Patients undergoing chemotherapy for cancer frequently experience fatigue, which can significantly lower their quality of life and interfere with treatment. However, the risk factors for the occurrence of chemotherapy-induced fatigue (CIF) are unclear. In this study, we investigated the occurrence of CIF in 415 patients newly treated with chemotherapy at Fukuoka University Hospital between December 2020 and July 2022, and analyzed the factors that influence the occurrence of fatigue. The observation period was defined as the two-week period starting from the day after the induction of chemotherapy, and we collected data retrospectively from medical records. Fatigue was assessed based on Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 by pharmacists who interviewed patients. The prevalence of fatigue was 56.4% (234/415). Nausea and vomiting, anorexia, hypoalbuminemia, and a high blood urea nitrogen/creatinine (BUN/Cr) ratio were extracted as risk factors for CIF. The prevalence of fatigue in 95 patients with nausea and vomiting was 83.2% (79/95), of whom 74.7% (59/79) had concomitant anorexia. Patients with nausea and vomiting had a high prevalence of both fatigue and anorexia, indicating that control for nausea and vomiting is crucial for the prevention of CIF. The serum albumin level reflects the nutritional status of patients approximately three weeks before chemotherapy, and BUN/Cr ≥20 indicates dehydration. Patients with a poor nutritional status or dehydration should be closely monitored for fatigue before and during treatment. These findings offer new prospects for healthcare providers to avoid or reduce CIF and improve patients' quality of life by early control of CIF risk factors.

Most bothersome symptom in migraine and probable migraine: A population-based study.

Recently, the most bothersome symptom has been recommended as a co-primary endpoint in clinical trials on the acute treatment of migraine. Probable migraine is a subtype of migraine that fulfills all but one criterion for migraine diagnosis. We aimed to compare the most bothersome symptom between probable migraine and migraine. This study analyzed data from a nationwide study conducted in Korea, and the most bothersome symptom was assessed by requesting the participants to select one of the four typical accompanying symptoms of migraine. Responses to acute treatment were evaluated using the migraine Treatment Optimization Questionnaire-6. Nausea was the most bothersome symptom, followed by phonophobia and vomiting in the migraine group (nausea, 61.8%; phonophobia, 25.3%; vomiting, 10.0%; and photophobia, 2.9%) and the probable migraine group (nausea, 82.2%; phonophobia, 9.5%; vomiting, 5.6%; and photophobia, 2.7%). In participants with migraine, vomiting (adjusted odds ratio = 6.513; 95% confidence interval, 1.763-24.057) and phonophobia (adjusted odds ratio = 0.437; 95% confidence interval, 0.206-0.929) were significantly associated with severe headache intensity and nausea was significantly associated with >3 headache days per 30 days (adjusted odds ratio = 0.441; 95% confidence, 0.210-0.927). Different patterns of associations were observed in probable migraine.

Association of gastrointestinal symptoms and skipping breakfast with anxiety and depressive symptoms in quarantined Chinese college students during the Shanghai 2022 lockdown: a cross sectional survey.

BACKGROUND: This study aimed to evaluate the prevalence of anxiety and depressive symptoms among quarantined college students at school in Shanghai 2022 lockdown during the COVID-19 pandemic and investigate the association of gastrointestinal discomfort related-factors and skipping breakfast with anxiety and depressive symptoms. METHODS: 384 quarantined college students in Shanghai China were recruited in this cross-sectional study from April 5th to May 29th, 2022. Generalized Anxiety Disorder (GAD-7) and Patient Health Questionnaire (PHQ-9) were used to assess anxiety and depressive symptoms, respectively. RESULTS: The prevalence of anxiety and depressive symptoms were 56.8% and 62.8%, respectively. Longer quarantine duration, higher education level, skipping breakfast, stomachache or abdominal pain, and nausea or dyspepsia were significantly associated with anxiety symptoms. Moreover, longer quarantine duration, being woman, skipping breakfast, stomachache or abdominal pain, and nausea or dyspepsia were markedly related to depressive symptoms. Notably, regularly physical exercising and taking positive attitude towards COVID-19 were negatively correlated with anxiety and depressive symptoms. CONCLUSIONS: More attention should be paid to anxiety and depressive symptoms of quarantined college students and universities should provide timely psychological monitoring and intervention services to mitigate the impact of negative emotions on students. Effectively relieving gastrointestinal symptoms, insisting on eat breakfast, regularly exercising, and taking a positive attitude towards to COVID-19 might contribute to preventing the anxiety and depressive symptoms for those college students experiencing a long-term quarantine.

Prevalence and burden of nausea and vomiting in pregnant women: Interim analysis of the PURITY survey.

OBJECTIVES: Nausea and vomiting in pregnancy is a common and invalidating condition in early pregnancy. However, no data are available on its prevalence in Italy. This survey aims to evaluate the prevalence and impact of nausea and vomiting during pregnancy on the quality of life of Italian women. STUDY DESIGN: The survey was performed in three Italian public University Hospitals in two distinct periods: a first interview took place between the 18th and 22nd week of pregnancy, using the Questionnaire for Pregnancy Period (14 questions regarding demographic data and 30 questions about nausea and vomiting in pregnancy, including Pregnancy-Unique Quantification of Emesis questionnaire), and a follow-up interview, by telephone call, took place immediately after giving birth and in any case within 14 days of delivery, using the Questionnaire for Post-Pregnancy (9 questions). Included women were Caucasian, in physiological pregnancy and between the 18th and 22nd week (time of morphological ultrasound), able to communicate adequately with the interviewer, understand the questionnaires and able to provide valid informed consent. Twin pregnancies and women who recurred to medically assisted procreation were excluded. This is an interim report on data collected from 232 of the planned 600 women. RESULTS: Mean age of the recruited subjects was 32.6 ± 4.6 years, with approximately 60% primiparous. The prevalence of nausea and vomiting in pregnancy in the sample examined was 65.5% overall (152 out of 232 subjects). Of these 152 women, 63 (41.4%) experienced only nausea, 6 (3.9%) only vomiting, and 83 (54.6%) reported both. Symptoms were reported to begin at 7.2 ± 2.7 weeks, lasted 10.2 ± 5.6 weeks, and persisted at the time of the interview in 32.2% of cases. Overall, over 50% of the women interviewed experienced a negative impact of nausea and vomiting in pregnancy on social relationships and work activity. CONCLUSIONS: A high prevalence of nausea and vomiting in pregnancy, 65.5% overall, was found in this interim analysis. These symptoms appeared capable of negatively influencing women quality of life. Screening procedures should be offered during pregnancy and measures that address nausea and vomiting in pregnancy impact warranted.

Effects of Fasting versus Non-Fasting on Emetic Complications in Radiological Examinations Using Intravascular Non-Ionic Iodinated Contrast Media: A Systematic Review and Meta-Analysis.

OBJECTIVE: To compare the incidence of aspiration pneumonia, nausea, and vomiting after intravascular administration of non-ionic iodinated contrast media (ICM) between patients who fasted before contrast injection and those who did not. MATERIALS AND METHODS: Ovid-MEDLINE and Embase databases were searched from their inception dates until September 2022 to identify original articles that met the following criteria: 1) randomized controlled trials or observational studies, 2) separate reports of the incidence of aspiration pneumonia, nausea, and vomiting after intravascular injection of non-ionic ICM, and 3) inclusion of patients undergoing radiological examinations without fasting. A bivariate beta-binomial model was used to compare the risk difference in adverse events between fasting and non-fasting groups. The I² statistic was used to assess heterogeneity across the studies. RESULTS: Ten studies, encompassing 308013 patients (non-fasting, 158442), were included in this meta-analysis. No cases of aspiration pneumonia were reported. The pooled incidence of nausea was 4.6% (95% confidence interval [CI]: 1.4%, 7.8%) in the fasting group and 4.6% (95% CI: 1.1%, 8.1%) in the non-fasting group. The pooled incidence of vomiting was 2.1% (95% CI: 0.0%, 4.2%) in the fasting group and 2.5% (95% CI: 0.7%, 4.2%) in the non-fasting group. The risk difference (incidence in the non-fasting group-incidence in the fasting group) in the incidence of nausea and vomiting was 0.0% (95% CI: -4.7%, 4.7%) and 0.4% (95% CI: -2.3%, 3.1%), respectively. Heterogeneity between the studies was low (I² = 0%-13.5%). CONCLUSION: Lack of fasting before intravascular administration of non-ionic ICM for radiological examinations did not increase the risk of emetic complications significantly. This finding suggests that hospitals can relax fasting policies without compromising patient safety.

Gastrointestinal adverse events of tirzepatide in the treatment of type 2 diabetes mellitus: A meta-analysis and trials sequential analysis.

BACKGROUND: Tirzepatide (TZP) is a novel drug for type 2 diabetes mellitus (T2DM), but the gastrointestinal (GI) adverse events (AEs) is a limiting factor in clinical application. Therefore, this study systematically evaluated the GI AEs of TZP for T2DM. METHODS: Clinical trials of TZP for T2DM were retrieved from eight databases published only from the establishment of the database to February 2023. Revman5.3 and TSA0.9.5.10 Beta were used for meta-analysis and trials sequential analysis (TSA). RESULTS: Meta-analysis showed that compared with placebo, total GI AEs, nausea, decreased appetite, constipation and vomiting were significantly higher in all dose groups of TZP (P < .05), while abdominal pain and abdominal distension were comparable (P > .05). TSA showed that the differences in total GI AEs, nausea, decreased appetite and constipation were conclusive. Compared with insulin, nausea, diarrhea, vomiting and decreased appetite were significantly increased in all doses of TZP (P < .05), and dyspepsia was significantly increased with TZP 15 mg (P < .05). TSA showed that these differences were all conclusive. Compared with GLP-1 RA, decreased appetite was significantly higher with TZP 5 mg, total GI AEs, decreased appetite and diarrhea were significantly higher with TZP 10 mg (P < .05), while nausea, vomiting, dyspepsia and constipation were significantly different in all dose groups, abdominal pain were not significantly different (P < .05) and TSA showed no conclusive results in this group. CONCLUSION: The GI AEs of TZP were significantly higher than those of placebo and insulin, but comparable to GLP-1 RA. Nausea, diarrhea and decreased appetite are very common GI AEs of TZP, and the incidence is positively correlated with dose. GI AEs of TZP decrease gradually over time, so long-term steady medication may be expected to reduce GI AEs.

Adverse Drug Reactions to Opioids: A Study in a National Pharmacovigilance Database.

INTRODUCTION: Opioids are commonly used as analgesics; however, like any medicine, they can produce adverse drug reactions (ADRs), including nausea, constipation, dependence, and respiratory depression, that result in harmful and fatal events. Therefore, it is essential to monitor the safety of these drugs in clinical practice. OBJECTIVE: This study aimed to characterize the safety profile of opioids by conducting a descriptive study based on a spontaneous reporting system (SRS) for ADRs in The Netherlands, focusing on abuse, misuse, medication errors, and differences between sexes. METHODS: Reports submitted to the Netherlands Pharmacovigilance Centre Lareb from January 2003 to December 2021 with an opioid drug as the suspected/interacting medicine were analyzed. Reporting odds ratios (RORs) for drug-ADR combinations were calculated, analyzed, and corrected for sex and drug utilization (expenditure) for the Dutch population. RESULTS: A total of 8769 reports were analyzed. Tramadol was the opioid with the most reports during the period (n = 2746), while oxycodone or tramadol had the highest number of reports per year in the study period. The most reported ADRs from opioid use were nausea, followed by dizziness and vomiting, independent of sex, and all of them were more often reported in women. Vomiting associated with tramadol (ROR females/males = 2.17) was significantly higher in women. Buprenorphine was responsible for most ADRs when corrected for expenditure, with high RORs observed with application site hypersensitivity, application site reaction, and application site rash. Fentanyl gave rise to most of the reports of ADRs concerning abuse, misuse, and medication errors. CONCLUSION: Patients treated with opioids experienced ADRs, primarily nausea, dizziness, and vomiting. For those groups of drugs, no significant differences were found between the sexes, except for the vomiting associated with tramadol. In general, ADRs related to opioids presented higher RORs when uncorrected and corrected for sexes and expenditure than other drugs. There was more disproportionate reporting for ADRs concerning abuse, misuse, and medication errors for opioids than other drugs in the Dutch SRS.
