Female sex hormones have been hypothesized to influence the higher prevalence of gastroparesis in females. This study investigated the effects of hormone replacement therapy (HRT) on gastroparesis and its related symptoms, medication use, and diagnostic testing in post-menopausal women. Utilizing the TriNetX platform, we conducted a population-based cohort study involving post-menopausal women aged 50 or older, with and without HRT. One-to-one propensity score matching was performed to adjust for age, race, ethnicity, diabetes, body mass index (BMI), and hemoglobin A1c. The exclusion criteria included functional dyspepsia, cyclic vomiting syndrome, and surgical procedures. After applying the exclusion criteria, we identified 78,192 post-menopausal women prescribed HRT and 1,604,822 not prescribed HRT. Post-propensity matching, each cohort comprised 67,874 patients. A total of 210 of the post-menopausal women prescribed HRT developed an ICD encounter diagnosis of gastroparesis at least 30 days after being prescribed HRT compared to post-menopausal women not prescribed HRT (OR = 1.23, 95% CI [1.01-1.51] -value = 0.0395). These associations persisted in sensitivity analysis over 5 years (OR = 1.65, 95% CI [1.13-2.41] -value = 0.0086). HRT was associated with increased GI symptoms, including early satiety (OR = 1.22, 95% CI [1.03-1.45] -value = 0.0187), domperidone use (OR = 2.40, 95% CI [1.14-5.02] -value = 0.0163), and undergoing gastric emptying studies (OR = 1.67, 95% CI [1.39-2.01] -value < 0.0001). HRT is linked to an increased risk of developing an ICD encounter diagnosis of gastroparesis.

Observational Study
BACKGROUND OBJECTIVES
Irrational prescribing practices have major consequences on patient safety and also increase the economic burden. Real-life examples of impact of irrational prescription have potential to improve prescribing practices. In this context, the present study aimed to capture and evaluate the prevalence of deviations from treatment guidelines in the prescriptions, potential consequence/s of the deviations and corrective actions recommended by clinicians.
METHODS
It was a cross-sectional observational study conducted in the outpatient departments of tertiary care hospitals in India wherein the 13 Indian Council of Medical Research Rational Use of Medicines Centres are located. Prescriptions not compliant with the standard treatment guidelines and incomplete prescriptions with respect to formulation, dose, duration and frequency were labelled as 'prescriptions having deviations'. A deviation that could result in a drug interaction, lack of response, increased cost, preventable adverse drug reaction (ADR) and/or antimicrobial resistance was labelled as an 'unacceptable deviation'.
RESULTS
Against all the prescriptions assessed, about one tenth of them (475/4838; 9.8%) had unacceptable deviations. However, in 2667/4838 (55.1%) prescriptions, the clinicians had adhered to the treatment guidelines. Two thousand one hundred and seventy-one prescriptions had deviations, of which 475 (21.9%) had unacceptable deviations with pantoprazole (n=54), rabeprazole+domperidone (n=35) and oral enzyme preparations (n=24) as the most frequently prescribed drugs and upper respiratory tract infection (URTI) and hypertension as most common diseases with unacceptable deviations. The potential consequences of deviations were increase in cost (n=301), ADRs (n=254), drug interactions (n=81), lack of therapeutic response (n=77) and antimicrobial resistance (n=72). Major corrective actions proposed for consideration were issuance of an administrative order (n=196) and conducting online training programme (n=108).
INTERPRETATION CONCLUSIONS
The overall prevalence of deviations found was 45 per cent of which unacceptable deviations was estimated to be 9.8 per cent. To minimize the deviations, clinicians recommended online training on rational prescribing and administrative directives as potential interventions.

BACKGROUND
Esophageal squamous cell carcinoma (ESCC) is one of the leading causes of digestive system tumor related death in the world. Unfortunately, effective chemopreventive agent is lack for patients with ESCC in clinical practice, which leads to the extremely high mortality rate.
METHODS
A library of prescribed drugs was screened for finding critical anti-tumor properties in ESCC cells. The phosphoproteomics, kinase array, pulldown assay and drug affinity responsive target stabilization assay (DARTS) were applied to explore mechanisms and searched for synergistic targets. Established models of PDX in mice were used to determine the therapeutic effect of domperidone.
RESULTS
After screening a library of prescribed drugs, we discovered that domperidone has anti-tumor properties. Domperidone, acting as a gastroprokinetic agent, has been widely used in clinic for gastrointestinal motility disorders. Despite limited research, there are indications that domperidone may have anti-tumor properties. In this study, we determined that domperidone significantly inhibited ESCC proliferation in vitro and in vivo. We employed phosphoproteomics to reveal p-ERK, and p-SMAD3 down-regulation upon domperidone treatment. Then, the results of kinase assay and pulldown assay further validated that domperidone directly combined with MEK1/2 and CDK4, leading to the inhibition of their kinase activity. Furthermore, our results revealed that MEK/ERK and CDK4/SMAD3 signal pathway were major pathways in domperidone against ESCC.
CONCLUSION
Collectively, these findings suggest that domperidone serves as an effective "multi-target" inhibitor of MEK1/2 and CDK4, offering potential benefits for the chemoprevention of ESCC.

The present study was designed to evaluate the antiemetic activity of abietic acid (AA) using in vivo and in silico studies. To assess the effect, doses of 50 mg/kg b.w. copper sulfate (CuSO⋅5HO) were given orally to 2-day-old chicks. The test compound (AA) was given orally at two doses of 20 and 40 mg/kg b.w. On the other hand, aprepitant (16 mg/kg), domperidone (6 mg/kg), diphenhydramine (10 mg/kg), hyoscine (21 mg/kg), and ondansetron (5 mg/kg) were administered orally as positive controls (PCs). The vehicle was used as a control group. Combination therapies with the referral drugs were also given to three separate groups of animals to see the synergistic and antagonizing activity of the test compound. Molecular docking and visualization of ligand-receptor interaction were performed using different computational tools against various emesis-inducing receptors (D, D, 5HT, H, and M-M). Furthermore, the pharmacokinetics and toxicity properties of the selected ligands were predicted by using the SwissADME and Protox-II online servers. Findings indicated that AA dose-dependently enhances the latency of emetic retching and reduces the number of retching compared to the vehicle group. Among the different treatments, animals treated with AA (40 mg/kg) exhibited the highest latency (98 ± 2.44 s) and reduced the number of retching (11.66 ± 2.52 times) compared to the control groups. Additionally, the molecular docking study indicated that AA exhibits the highest binding affinity (- 10.2 kcal/mol) toward the M receptors and an elevated binding affinity toward the receptors 5HT (- 8.1 kcal/mol), M (- 7.7 kcal/mol), M (- 8.7 kcal/mol), and H (- 8.5 kcal/mol) than the referral ligands. Taken together, our study suggests that AA has potent antiemetic effects by interacting with the 5TH and muscarinic receptor interaction pathways. However, additional extensive pre-clinical and clinical studies are required to evaluate the efficacy and toxicity of AA.

BACKGROUND
We present a case of non-puerperal induced lactation in transgender woman. Medical literature on lactation induction for transgender women is scarce, and the majority of literature and protocols on lactation induction is based on research in cisgender women. Healthcare professionals may lack the precise knowledge about lactation induction and may therefore feel insecure when advice is requested. Subsequently, there is a rising demand for guidelines and support.
METHODS
Patient medical record was consulted and a semi-structured interview was conducted to explore the motive for lactation induction, the experience of lactation induction, and to gather additional information about the timeline and course of events.
CASE PRESENTATION
In this case a 37-year-old transgender woman, who was under the care of the centre of expertise on gender dysphoria in Amsterdam, and in 2020 started lactation induction because she had the wish to breastfeed her future infant. She was in a relationship with a cisgender woman and had been using gender affirming hormone therapy for 13 years. Prior to initiating gender affirming hormone therapy she had cryopreserved her semen. Her partner conceived through Intracytoplasmic Sperm Injection, using our patient's cryopreserved sperm. To induce lactation, we implemented a hormone-regimen to mimic pregnancy, using estradiol and progesterone, and a galactogogue; domperidone. Our patient started pumping during treatment. Dosage of progesterone and estradiol were significantly decreased approximately one month before childbirth to mimic delivery and pumping was increased. Our patient started lactating and although the production of milk was low, it was sufficient for supplementary feeding and a positive experience for our patient. Two weeks after birth, lactation induction was discontinued due to suckling problems of the infant and low milk production.
CONCLUSIONS
This case report underlined that lactation induction protocols commonly used for cisgender women are also effective in transgender women. However, the amount of milk produced may not be sufficient for exclusive nursing. Nevertheless, success of induced lactation may be attributed to its importance for parent-infant bonding, rather than the possibility of exclusive chestfeeding.

The current research proposed a highly sensitive and selective spectrofluorometric approach for the assay of gastrointestinal medications omeprazole (OMZ) and domperidone (DOM). Green synthesis of metal oxide nanoparticles such as zinc oxide (ZnONPs) and cerium oxide (CeONPs) using and extract was used as fluorescence emission catalysts for the determination of OMZ and DOM. Due to their unique optical properties, nanoparticles (NPs) form the basis for spectrofluorimetric quantification of the selected drugs. The detection studies were performed under λex/λem 350/450 nm and 284/392 nm for OMZ and DOM in the presence of ZnONPs and CeONPs, respectively. Under ideal conditions, fluorescence intensities (FI) were linearly with correlation coefficient (r = 0.999) over concentration ranges of 0.1-100 and 0.01-200 μg mL for OMZ, 0.01-100 and 0.01-300 g mL for DOM in the presence of ZnONPs and CeONPs, respectively. Method validation was carried out to guarantee the accuracy, suitability, and precision of the proposed fluorescence (FL) systems for the determination of OMZ and DOM. Analytical method guidelines and requirements were followed. The designed procedure was used effectively to identify the determined drugs in both their pure and commercial versions.

Domperidone is used as an immunomodulatory drug for infection and disease in dogs. However, a pro-arrhythmic side effect, caused by prolonged QT intervals, is reported in humans. This pilot study evaluated the corrected QT (QTc) interval in dogs treated with domperidone for preventive or therapeutic management of leishmaniosis. The electrocardiogram and blood concentration of creatinine, urea nitrogen, sodium, potassium, and chloride were evaluated seven days before the start and on the last day of therapy in 17 dogs receiving domperidone for four weeks. In two dogs, the QTc interval was measured before and 2 h, 3 h, and 12 h after administration of the drug on the first day of treatment. After treatment, QTc measures and chloride concentrations increased significantly, although the QTc value slightly exceeded the upper reference limit only in one dog, and chloride concentrations were always normal. Creatinine concentrations significantly decreased after therapy. In the two dogs monitored at different times on the first day of treatment, QTc values were always normal. Domperidone caused a slight prolongation of QTc interval, and further studies should be made for a risk assessment in dogs with cardiac diseases, electrolytic imbalance, and in those receiving drugs increasing QT interval or competing with domperidone metabolism.

The commonest medications prescribed in functional dyspepsia are prokinetic agents, specifically domperidone. However, its administration at times elevates serum prolactin levels, which can lead to pathological hyperprolactinemia. The present study investigated the effect of 28 days of 30 mg domperidone therapy on prolactinemia in functional dyspepsia patients. We recruited 97 patients (60 men and 37 women, aged 18-80 years) who had functional dyspepsia diagnosed as per the Rome IV criteria. After taking a preliminary clinical history, we measured and compared serum prolactin levels at day 'zero' and day 'twenty-eight'. We found increased prolactin levels from day '0' to day '28' after treatment with domperidone in functional dyspepsia patients, specifically in male participants aged less than 40 years, who are married and belong to middle socioeconomic status. The most common functional dyspepsia symptom found was pain in the epigastric region. To conclude, our pragmatic domperidone-induced-hyperprolactinemia link warrants this side effect to be robustly taken into account while treating functional dyspepsia patients with domperidone.

Quercetin (QUA), a flavonoid compound, is ubiquitously found in plants and has demonstrated a diverse range of biological activities. The primary objective of the current study is to assess the potential antiemetic properties of QUA using an in vivo and in silico approach. In this experiment, 4-day-old chicks were purchased to induce emesis by orally administering copper sulfate pentahydrate (CuSO·5HO) at a dose of 50 mg/kg (orally). Domperidone (DOM) (6 mg/kg), Hyoscine (HYS) (21 mg/kg), and Ondansetron (OND) (5 mg/kg) were treated as positive controls (PCs), and distilled water and a trace amount of Tween 80 mixture was employed as a negative control (NC). QUA was given orally at two distinct doses (25 and 50 mg/kg). Additionally, QUA (50 mg/kg) and PCs were administered separately or in combination to assess their antagonistic or synergistic effects on the chicks. The binding affinity of QUA and referral ligands towards the serotonin receptor (5HT3), dopamine receptors (D2 and D3), and muscarinic acetylcholine receptors (M1-M5) were estimated, and ligand-receptor interactions were visualized through various computational tools. In vivo findings indicate that QUA (25 and 50 mg/kg) has a significant effect on reducing the number of retches (16.50 ± 4.65 and 10.00 ± 4.19 times) and increasing the chick latency period (59.25 ± 4.75 and 94.25 ± 4.01 s), respectively. Additionally, QUA (50 mg/kg) in combination with Domperidone and Ondansetron exhibited superior antiemetic effects, reducing the number of retches and increasing the onset of emesis-inducing time. Furthermore, it is worth noting that QUA exhibited the strongest binding affinity against the D2 receptor with a value of -9.7 kcal/mol through the formation of hydrogen and hydrophobic bonds. In summary, the study found that QUA exhibited antiemetic activity in chicks, potentially by interacting with the D2 receptor pathway.
