(1) Background: Diet holds a pivotal position in exacerbating or ameliorating chronic inflammation, which has been implicated in the pathogenesis of hyperemesis gravidarum (HG). However, no study has explored the association between dietary inflammatory potential and HG. This study aimed to investigate the potential correlation between following a pro-inflammatory diet and the likelihood of developing HG. (2) Methods: A total of 2033 Chinese pregnant women (mean age: 31.3 ± 3.4 years) were included in this cross-sectional study from April 2021 to September 2022 as part of the China Birth Cohort Study (CBCS). Dietary inflammatory index (DII) scores with 23 food components were constructed through dietary intakes collected via a reliable 108-item semi-quantitative food frequency questionnaire. HG was defined as a pregnancy-unique quantification of emesis (PUQE) score ≥13 points, severe nausea and vomiting leading to weight loss ≥5%, or being hospitalized for treatment due to the disease. The relationship between DII and HG was conducted utilizing binary logistic regression and restricted cubic spline regression. (3) Results: Overall, 8.2% (n = 167) of study participants had HG. The DII scores ranged from -4.04 to 3.82. After adjusting for potential confounders, individuals with the highest tertile of DII score had a higher risk of HG (OR = 1.65, 95% CI: 1.04, 2.62, Ptrend = 0.032). Such an association was stronger in those with pre-pregnancy overweight/obesity (Pinteraction = 0.018). (4) Conclusions: A higher DII score, which serves as a marker for a diet promoting inflammation, is correlated with an elevated risk of developing HG. This finding suggests that dietary recommendations for HG should focus on minimizing the DII through incorporating foods abundant in anti-inflammatory components.

UNASSIGNED: Nausea and vomiting occur in more than 70% of pregnant women,1 and only 2% of these females progress into hyperemesis gravidarum (HG).2 HG is the persistent and excessive vomiting before the 22nd week of gestation. HG patients can develop life-threatening electrolyte disturbances or thromboembolism. Pulmonary embolism (PE) is a thromboembolism that blocks and stops blood flow to an artery in the lung. Both HG and PE increase morbidity and mortality in pregnant patients. HG patients developing PE are reported only in two patients with fatal outcomes in the literature. We report a case of PE in a hospitalized HG patient with a better outcome.
UNASSIGNED: A 26-year-old previously healthy gravida 3 and para 2 patient was admitted to the Women Wellness and Research Center with HG at 10 weeks of gestation. She developed nausea and vomiting at 6 weeks of gestation and was treated in the emergency department, where she was started on intravenous (IV) fluids for hydration, an antiemetic, and deltaparin for prevention of deep venous thrombosis (DVT), as she was pregnant and dehydrated. She was on potassium replacement therapy for hypokalemia. The patient was improving; still had vomiting, but less frequent. On day 3, following admission, the patient suddenly developed hemoptysis, chest pain, and palpitation. She was tachycardic (120 bpm) and tachypneic (30 breaths per minute). She was feeling dizzy, and her oxygen saturation (Spo2) was around 95%. Her chest was clear on examination. Computerized tomographic pulmonary angiography showed bilateral PE. She was admitted to the highdependency unit. The patient was tachypneic and tachycardic and required non-invasive ventilation. A therapeutic dose of enoxaparin (1 mg/kg) was started and supplemented with fentanyl plus paracetamol for analgesia, continued IV fluids, and promethazine.Her respiratory symptoms and tachycardia improved by day 6, she was transferred to the ward from there and discharged home by day 10, on enoxaparin therapeutic dose (1 mg/kg), and follow up in outpatient clinics showed no issues, and she is doing fine.
UNASSIGNED: HG is a severe clinical disease in pregnancy where patients have intractable nausea and vomiting with increased morbidity and even mortality. These patients frequently present with ketonuria, dehydration, electrolyte abnormalities, and a weight loss of 7%. Rarely, these patients\' present with severe vitamin deficiency, causing a neurological emergency called Wernicke\'s encephalopathy. The occurrence of DVT is one of the main risk factors due to prothrombotic conditions in pregnancy in combination with dehydration in these patients. The occurrence of PE is reported in two cases of HG in the post-mortem. Our patient developed bilateral PE, a medical emergency due to immobility, dehydration, and prothrombotic predominance during pregnancy. PE was detected early and managed, leading to a better outcome.
UNASSIGNED: HG should be diagnosed early, followed by admission of the patient to the hospital. Our patient with HG was complicated by a rare bilateral PE due to a combination of pregnancy, dehydration, and immobility, despite DVT prophylaxis with a favorable outcome. Clinicians should have an index of suspicion for DVT and PE in these dehydrated pregnant patients. A high index of suspicion, early diagnosis, and management by a multidisciplinary team are key for better outcomes of PE in our HG patient.

UNASSIGNED: Hyperemesis Gravidarum (HG) is a severe form of nausea and vomiting in pregnancy that affects 0.3-3% of women and has profound nutritional, physical and psychological consequences. Research is lacking regarding the most effective management of the condition. In response to patient feedback, a multidisciplinary HG day-case service (IRIS Clinic) was launched in 2020 at The National Maternity Hospital, Ireland. The clinic provides routine, day-case care in a comfortable space with pre-booked appointments. The MDT involves midwives, dietitians, perinatal mental health, obstetrics and pharmacy, and the nature of the clinic enables peer-to-peer support. As this clinic is the first of its kind in Ireland, we aim to assess its effectiveness and feasibility, and suggest recommendations for improvement.
UNASSIGNED: This is a sequential, mixed-methods study that commenced in August 2021. The prospective arm of the study is ongoing and involves enrolling women (n = 50) who are attending the IRIS clinic. Data are collected on first admission (pre-intervention) and approximately 8 weeks\' later (post-intervention) relating to symptoms of HG, well-being, food tolerances, quality of life and nutritional intake. Qualitative, semi-structured interviews will be conducted to evaluate women\'s experiences of attending the clinic. The retrospective arm of the study will be a chart review (n = 200) of women diagnosed with HG to describe assessments, treatments and pregnancy and birth outcomes.
UNASSIGNED: The IRIS clinic has the potential to improve pregnancy outcomes and nutritional status among women with HG. If found to be effective and feasible, the model for this clinic could be replicated elsewhere.

Gayet-Wernicke encephalopathy (GWE) is a neuropsychiatric syndrome due to Vitamin B1 (thiamine) deficiency, fatal in 30% of cases and preventable if treatment is initiated early, characterized by the classic triad of encephalopathy, ocular involvement: ophthalmoplegia and/or nystagmus and ataxia. GWE is mainly observed in alcoholics, but can also appear in any state of malnutrition. In obstetrics, hyperemesis gravidarum can be complicated by GWE due to low thiamine stores and increased thiamine requirements. We report a case of Gayet-Wernicke encephalopathy complicating incoercible vomiting in a pregnant woman.

Marchiafava-Bignami disease (MBD) is uncommon and typically linked with persistent alcohol consumption; nevertheless, instances have been reported in non-alcoholic individuals with nutritional deficiencies. Depending on the severity, this condition may manifest as acute, subacute, or chronic neurological signs and symptoms, ranging from moderate dysarthria or mild disorientation to coma and death. We report a case of a 30-year-old, 14-week pregnant female who presented with complaints of persistent vomiting and loss of appetite. She was found to have achalasia cardia on upper GI endoscopy. Later, she developed confusion, irrelevant talks and her speech was incomprehensible. An MRI of the brain was done which showed features likely that of MBD. She was started high dose intravenous thiamine to which she responded brilliantly.

UNASSIGNED: Hyperemesis gravidarum is one of the problems encountered among pregnant women due to persistent and excessive vomiting starting before the end of the 22nd week of gestation. The current study aimed to assess the prevalence of hyperemesis gravidarum and associated factors among pregnant women at comprehensive specialized hospitals in northwest Ethiopia.
UNASSIGNED: A multi-facility-based cross-sectional study was conducted at comprehensive specialized hospitals from 1st June 2022 to 30th July 2022. The data were entered using EPI Data Version 4.6 statistical software and analyzed using SPSS Version 26. Descriptive statistics such as frequency, mean, and percentage were calculated. Univariable and multivariable binary logistic regression analyses were carried out to identify the associated factors of hyperemesis gravidarum.
UNASSIGNED: In all, 404 study participants were enrolled. About 16.8% of pregnant women were found to have hyperemesis gravidarum. Age < 20 year (AOR = 3.170; 95% CI: 1.119, 8.980), study participants who cannot read and write (AOR = 5.662; 95% CI: 2.036, 15.7470), grade 1-8 (AOR = 4.679; 95% CI: 1.778, 12.316), and grade 9-10 (AOR = 8.594; 95% CI: 3.017, 24.481), being housewife (AOR = 6.275; 95% CI: 1.052, 37.442), living in urban area (AOR = 2.185; 95% CI: 1.035, 4.609), having previous hyperemesis gravidarum (AOR = 2.463; 95% CI: 1.210, 5.012), having family history of hyperemesis gravidarum (AOR = 2.014; 95% CI: 1.002, 4.047), unplanned pregnancy (AOR = 2.934; 95% CI: 1.030, 8.351), having recent abortion (AOR = 2.750; 95% CI: 1.010, 7.483), and gravidity (AOR = 1.956; 95%CI: 1.023, 3.737) were factors associated with hyperemesis gravidarum.
UNASSIGNED: The prevalence of hyperemesis gravidarum is higher. Low maternal age, lower educational level, being a housewife, being an urban resident, having previous hyperemesis gravidarum, having a family history, having an unplanned pregnancy, and having a recent abortion were significantly associated with hyperemesis gravidarum.

Pregnancy-associated gastric cancer is extremely rare. In many cases, the cancer is already advanced at the time of diagnosis, and the prognosis is often poor. A 39-year-old primigravida, with dichorionic diamniotic twins, was admitted to our hospital for threatened preterm labor at 31 weeks of gestation. At 32 weeks of gestation, she developed a fever and tested positive for influenza A. She recovered from influenza A on the following day but had an emergency cesarean section for premature rupture of the membranes at 32 weeks of gestation. She was discharged on postpartum day six. Thereafter, she was again infected with influenza A. On day 18, she underwent an abdominal ultrasound revealing multiple mass lesions in the liver, because she had an uncomfortable upper gastric with persistent fever. She was referred to the internal medicine team, who made a diagnosis of stage IV gastric cancer. Importantly, non-specific symptoms and physical signs that are not explicable by the normal course of pregnancy may be recognized through conscientious history-taking and physical observations. If gastrointestinal symptoms are prolonged, or if symptoms such as severe weight loss, melena, a tender abdominal mass, or persistent and unexplained fever develop, an endoscopic assessment should be conducted to suspect other diseases. In addition, proactive ultrasound scanning, including the upper abdomen, may detect pregnancy-associated gastric cancer and lead to further in-depth investigations.

UNASSIGNED: Observational studies have reported an association between the gut microbiota (GM) and hyperemesis gravidarum (HG). However, the causal relationship is unclear. In this study, Mendelian randomization (MR) was used to infer causal relationships between GM and HG.
UNASSIGNED: Inverse-variance weighted MR was performed using summary statistics for genetic variants from genome-wide association studies (GWAS). Sensitivity analyses were performed to validate the MR results and assess the robustness of the causal inference. Reverse MR analysis was performed for bacterial taxa that were causally linked to the HG risk in the forward MR analysis to evaluate reverse causality.
UNASSIGNED: MR analysis revealed that the genera Defluviitaleaceae UCG011, Ruminococcus1, Ruminococcus2, Turicibacter, and unknowngenus and phylum Verrucomicrobiota are positively associated with the risk of HG. Additionally, the genus Coprococcus2 was related to a decreased risk of HG. Sensitivity studies validated the strength and reliability of the link between the composition of the GM and HG. No evidence for reverse causality from HG to identified bacterial taxa was found.
UNASSIGNED: Our MR analysis provided novel insight into the association between GM and HG. In particular, our results indicated that targeting the GM could serve as an effective therapeutic strategy for HG.
