Increasing nausea and vomiting of pregnancy is associated with sex-dependent differences in early childhood growth: the GUSTO mother-offspring cohort study

Background Nausea and vomiting of pregnancy (NVP) is common and underlying mechanisms are poorly understood. Longer-term offspring outcomes are also not well documented. This study aimed to determine if NVP, even in milder forms, is associated with adverse pregnancy and childhood growth outcomes. Methods In the GUSTO prospective mother-offspring cohort, women with singleton pregnancies (n = 1172) recruited in first trimester responded to interviewer-administered questions at 26–28 weeks’ gestation about earlier episodes of NVP since becoming pregnant. Pregnancy outcomes were obtained from medical records. Offspring height and weight measured at 15 time-points between birth to 72 months (m) were standardised for age and sex. Results 58.5% (n = 686) reported mild-moderate vomiting (mNVP), 10.5% (n = 123) severe vomiting (sNVP) and 5.7% (n = 67) severe vomiting with hospitalisation (shNVP). There was no difference in odds of gestational diabetes, hypertensive disorders of pregnancy, labour induction or caesarean section after adjustment for covariates. sNVP was associated with late preterm delivery [34+ 0–36+ 6 weeks’, adjusted OR = 3.04 (95% CI 1.39,6.68)], without increased odds of neonatal unit admission. Compared with no NVP, boys born to mothers with sNVP were longer at birth [adjusted β = 0.38 standard deviations (SDs) (95% CI 0.02,0.73)], remained taller [0.64 SDs (0.23,1.04) at 72 m] and heavier [0.57 SDs (0.05,1.08) at 60 m] without differences in BMI. Conversely, girls born to mothers with shNVP were lighter from 48 m [− 0.52 SDs (− 1.00, − 0.03)] onwards with lower BMI [− 0.61 SDs (− 1.12,-0.09)]. Conditional growth modelling revealed significant sex-divergence in weight-gain at birth-3 m, 6-9 m and 4–5 years. Conclusions Severe NVP was associated with late preterm delivery, and both mild-moderate and severe NVP associated with sex-dependent differences in early childhood growth. Boys whose mothers had NVP were taller and heavier from birth with faster growth in the first year, whereas, girls had poorer weight gain and were lighter by 48 m. As even milder severities of NVP could have long-term impact on offspring growth, further research is needed to determine mechanisms involved and implications on future health.

Predictive value of clinical toxicities of chemotherapy with fluoropyrimidines and oxaliplatin in colorectal cancer by DPYD and GSTP1 gene polymorphisms

Background: Fluoropyrimidines and platinum are still widely used for colorectal cancer (CRC) management. Several studies have reported that mutations of dihydropyrimidine dehydrogenase (DPYD) and glutathione S-transferase pi-1 (GSTP1) polymorphisms are related to Chemotherapy-related adverse events. In the present study, we purposed to assess the impact of DPYD and GSTP1 variants on the toxicity of adjuvant chemotherapy risk among the Hakka population, minimize adverse events, and to maximize therapy outcome for individualized treatment.Methods: Genotyping was examined in 104 patients diagnosed with CRC cases and receiving fluoropyrimidine and platinum drugs based chemotherapy regimen by direct sequencing of DPYD and GSTP1 polymorphisms. Three DPYD variants including *2A, *5A, *9A, and GSTP1 c.313A>G were analyzed and clinical outcomes were assessed.Results: The data suggest that the incidence of DPYD*5A, DPYD*9A, and GSTP1 c.313A>G variants were 38.4%, 24%, and 32.7%, respectively. DPYD*2A variant was not found. A total of 23 patients (22.1%) suffered severe vomiting and 19 patients (18.3%) suffered severe anemia. DPYD*5A polymorphism was found significantly associated with grade 3/4 ulceration (p = 0.001). GSTP1 was determined to be an independent risk factor for severe vomiting and skin ulceration (p = 0.042 and p = 0.018, respectively). Patients with GSTP1 c. 313A>G mutant type contributed to a higher risk for grade severe toxicity compared with wild genotype (p = 0.027). Nevertheless, no significant difference was found between patients with DPYD*2A, *5A, *9A for chemotherapeutic toxicity.Conclusions: The results demonstrated that GSTP1 polymorphisms were useful predictors of severe events. Screening of single nucleotide polymorphisms of GSTP1 in colorectal cancer patients before chemotherapy may help to realize personalized therapy.

PANCRA©ATITE AIGUE ET VOMISSEMENTS SA©VARES AU COURS DE LA GROSSESSE : A PROPOS DE 24 CAS

Introduction: The acute pancreatitis (PA) during pregnancy is rare conditions, the clinical signs of which are not specific and may be related to the pregnancy itself and cause a delayed diagnosis. Material And Method: Our study is a 6-month comparative study of 24 patients, 18 with severe vomiting during pregnancy without pancreatitis (VS) and 6 with severe vomiting during pregnancy associated with (PA). The aim of our work was to determine the percentage of acute pancreatitis among patients with severe vomiting during pregnancy and to identify the signs pointing more towards this pathology. Results: Twenty five percent of patients with severe vomiting had PA. In the 66.67% PA group were nulliparous. Abdominal pain was present in 83% of PA cases and in 55.46% cases of VS. Metabolic alkalosis was present in 60% of cases in the PA group and 31% in the VS group. Ultrasonography showed biliary origin in 66.67% of PA and in 16.67 of VS cases. There were no deaths in the 2 groups. Conclusion: Given the high percentage of pancreatic origin in our study (25%), we should always mention PA in pregnant women with severe vomiting.

Contralateral Spontaneous Rupture of the Esophagus Following severe Vomiting After Non-intubated Pulmonary Wedge Resection

Background: Non-intubated thoracoscopic lung surgery has been widely applied as it is technically feasible and safe. Spontaneous rupture of the esophagus, also known as Boerhaave's syndrome (BS), is rare after chest surgery.Case Presentation: A 60-year-old female non-smoker underwent non-intubated uniportal thoracoscopic wedge resection assisted with a laryngeal mask for a solitary pulmonary nodule. Ultrasound-guided serratus anterior plane block was utilized for analgesia. The patient complained of hyperemesis followed by chest pain and acute dyspnea 6 hours after the surgery. Emergency chest x-ray revealed the right-sided hydropneumothorax. BS was confirmed by further chest tube drainage and computed tomography. The patient refused surgical intervention; therefore, conservative procedures including pleural evacuation through a naso-leakage drainage tube, antibiotics and tube feeding were administered. The healing of the esophagus was recorded 40 days later.Conclusions: Perioperative antiemetic is an indispensable item of tubeless thoracic surgery. BS should be kept in mind when the patients suffer from sudden chest distress following severe vomiting after tubeless lung surgery.

Haematemesis and acute dysphagia: oesophagogastroduodenoscopy or CT—which one first?

We present an uncommon case of a patient presenting at the emergency department for severe vomiting, persisting for at least 12 hours, without nausea or abdominal pain. She initially referred vomiting food eaten several hours earlier and eventually a single episode of haematemesis with emission of a small amount of red blood and clots. She also reported the occurrence of acute dysphagia for solid food. The patient underwent oesophagogastroduodenoscopy (OGD), which showed that the lumen was almost completely narrowed by a submucosal bluish bulging from midoesophagus (19 cm from the incisors) to the cardia (located at 35 cm from the incisors). She therefore underwent chest CT showing a 15 cm long intramural oesophageal haematoma. Although the combination of vomiting and haematemesis is usually associated with Mallory-Weiss syndrome, in which a prompt OGD has a key role in the patient management, when these symptoms are associated with acute dysphagia, a possible intramural haematoma might be suspected. In this case, chest CT should take precedence, because it allows a quick and complete diagnostic appraisal. However, in this setting, although OGD can directly show typical findings (bluish swelling mucosa with or without a superficial tears), it might increase the risk of oesophageal haematoma rupture and intraluminal bleeding.
