Background: Inflammation is a response of the immune system to protect the body against various diseases or injuries. Serum trimethylamine N-oxide (TMAO) levels may vary depending on age, gender, habits, comorbidities, and microbiota.

Aims: In this study, we investigated whether TMAO levels have diagnostic significance and their potential as a marker in the early diagnosis of the disease. Another aim of the research was to identify changes in TMAO levels as a reflection of the deterioration in the microflora, and IL-6, IL-10, IL-1β, TNF-alpha, and LPS levels in patient groups. Then, we recognized relationships between these parameters in patients infected with COVID-19 without septic shock and with COVID-19 who were without transmission of COVID-19 in septic shock.

Study design: A total of 160 patients were investigated, including 40 patients infected with COVID-19 without septic contact, 40 patients with COVID-19 positive septic shock, 40 patients with COVID-19 negative septic shock, and 40 healthy individuals as the control group.

Results: TNF-α and IL-1β levels were significantly lower (P < 0.001) and IL-6 and IL-10 levels were significantly higher (P < 0.001) in patient groups than in control groups. IL-1β showed a significant decrease, especially in the groups infected with COVID-19. Although IL-6, increased even more in the groups infected with COVID-19.

Conclusions: LPS level was remarkably high in the sepsis group infected with COVID-19 compared to the other groups. TMAO level was significantly higher (P < 0.001) in the sepsis group. Therefore, TMAO is a potential biomarker in sepsis and septic shock.

Purpose: To evaluate the effectiveness of remimazolam in preventing adverse reactions triggered by carboprost tromethamine during cesarean section procedures.

Methods: A total of 200 parturients scheduled for cesarean sections at risk of postpartum hemorrhage in our hospital from October 2022 to July 2023 were included. The participants were assigned via random number table method to either a study group or a control group, resulting in 100 cases in each. All parturients received combined spinal and epidural anesthesia (CSEA) during cesarean section, followed by administration of carboprost tromethamine (250 µg) for preventing postpartum hemorrhage after childbirth. CSEA was performed with 1.8 to 2 mL of 0.5% bupivacaine and 7 to 10 mL of 2% lidocaine. The study group was given remimazolam via intravenous infusion at a rate of 0.3 mg/kg/h commencing at 1 minute prior to CSEA and concluding with a final dosage adjustment 20 minutes preceding the end of surgery, while the control group was given the same volume of saline within this time frame. Primary outcome measures were adverse reactions and sedative effects of the parturients.

Findings: Nausea and vomiting were the only adverse reactions that exhibited significant differences between groups. The study group reported significantly fewer cases (32 cases) of nausea and vomiting when compared to the 48 cases observed in the control group. Moreover, the use of remimazolam appeared to alleviate the severity of nausea and vomiting, as evidenced by the significantly lower incidence of Grade III event and the higher risk of Grade I event in comparison with the control group (P < 0.05). The Apgar scores of newborns at birth and 5 minutes after birth were compared, and no statistically significant difference was found (P > 0.05). Parturients receiving remimazolam exhibited better effective sedation outcomes and were more satisfied with the treatment when compared with controls (P < 0.05). There were no significant differences in postpartum bleeding volume at 2 and 12 hours postpartum, as well as in the duration of postpartum bleeding between the two groups (P > 0.05).

Implications: Intravenous administration of remimazolam effectively prevents adverse reactions induced by carboprost tromethamine during cesarean section performed under CSEA, thereby improving sedative effects.

Systemic estrogen therapies (SETs) are integral to health care, playing critical roles in reproductive rights, managing heavy menstrual bleeding (HMB), alleviating menopausal symptoms, and supporting gender-affirming hormone therapy (GAHT) for transwomen. However, SETs are associated with an increased risk of venous thromboembolism (VTE), posing a challenge in the acute care setting. Here, we explore the nuanced management of SETs in patients who present with a hormone-related VTE in the acute care setting. The prevailing practice of discontinuing SETs in this setting may lead to significant adverse effects, including exacerbation of HMB, unintended pregnancy, menopausal symptoms, and psychological distress from interrupted GAHT or hormone replacement therapy. The discontinuation of SETs can severely affect patients' health, quality of life, and adherence to anticoagulation therapy in the case of HMB, increasing the risk of VTE recurrence. We challenge the practice of broadly discontinuing SETs in the acute care setting, advocating for a patient-centered approach that considers the underlying reasons for SET use, potential adverse effects of abrupt cessation, and individual patient needs. We underscore the importance of shared decision making and individualized care, particularly for historically marginalized groups in health care, cis women, transwomen, and individuals with HMB, to ensure safe, equitable, and affirming health care. A tailored approach to managing SETs in the acute care setting will enhance health care delivery and reduce health inequities. Lastly, we highlight the need for further research, particularly regarding GAHT-related VTE for transwomen.

Background: The LUNAR clinical trial revealed that incorporating Tumor Treating Fields (TTFields) therapy alongside immune checkpoint inhibitor (ICI) significantly prolonged the overall survival of patients with metastatic, platinum-resistant non-small-cell lung cancer (NSCLC). However, the cost of TTFields therapy is high and may further increase the financial burden for patients. Our research aims to evaluate the cost-effectiveness of TTFields therapy addition with ICI for metastatic NSCLC.

Methods: We constructed a Markov model to evaluate the healthcare costs associated with TTFields therapy combined with ICI for the treatment of advanced NSCLC. In this model, the clinical data utilized came from the LUNAR trial, while drug costs and health state utility values were extracted from public databases and relevant scholarly publications. The major outcomes incorporated costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER).

Results: Compared with ICI therapy alone, ICI combination with TTFields therapy resulted in 0.42 QALYs at the cost of $167,329, with an ICER of $398,402.38 per year. The calculated ICER surpassed the generally accepted US willingness-to-pay (WTP) threshold of 150,000 per QALY. One-way sensitivity analyses demonstrated that the utility of progression disease is the most influential factor, followed by the cost of TTFields therapy, the utility of progression-free survival, the cost of ICI, and the cost of adverse events in TTFields therapy combined with ICI. Only when the cost of TTFields therapy is reduced by approximately 80.48%, it would be cost-effective within the commonly accepted WTP threshold of $150,000/QALY.

Conclusions: According to the US WTP, the combination of TTFields therapy with ICI does not currently represent a cost-effective strategy for metastatic NSCLC followed progression on platinum-resistant therapy. Considering its promising clinical outcomes for metastatic NSCLC, it is necessary to control the expenses of this therapeutic strategy in future applications.

Purpose: Ocular adverse events (oAEs) are a class of adverse events associated with oxaliplatin that are realistically observed in real-world settings. Herein, we aim to describe the clinical characteristics of oAEs associated with oxaliplatin through a systematic review of case reports and to assess a potential safety signal.

Methods: PubMed, Embase, and Cochrane Library databases were used to retrieve case reports. The global disproportionality study was performed leveraging the US Food and Drug Administration Adverse Event Reporting System database from January 2004 to September 2023. Bayesian information component (IC) and reporting odds ratio (ROR) were applied to identify and evaluate potential oAEs associated oxaliplatin.

Findings: A total of 20 cases from the systematic case review (of 13 screened articles) were reported on oAEs associated with oxaliplatin, with ages between 26 and 76 years. Therein, 16 (84.2%) cases described loss of vision, and the remaining cases presented with bilateral blepharoptosis, papilledema, and optic disc swelling. Insights from the US Food and Drug Administration Adverse Event Reporting System database showed that oAEs accounted for 4.28% (n = 1194) of the overall oxaliplatin-related adverse event reports, of which 1140 (95.48%) had a serious outcome. The median (interquartile range) onset time of oAEs with oxaliplatin was day 1 (0-25; n = 649). Disproportionality analysis revealed that ocular injuries NEC (n = 28, ROR, 22.72; lower limit of the 95% 2-sided CI for IC, 3.12) was the most significant signals detected. Additionally, unexpected significant oAEs, including eyelid ptosis, eyelid edema, eye movement disorder, blepharospasm, periorbital edema, swelling of eyelid, ophthalmoplegia, retinal vein thrombosis, cataract nuclear, blindness cortical, cataract subcapsular, and lacrimation disorder, were also reported disproportionality.

Implications: Our study systematically described the characteristics and outcomes of oxaliplatin-related ocular toxicity and also uncovered potential oAEs that were not disclosed in the package insert. Further prospective epidemiologic studies to validate these findings are warranted.
