Prenatal alcohol exposure (PAE) has been associated with reproductive dysfunction in offspring. However, studies in females, particularly examining long-term infertility or impacts on ovarian reserve, are lacking. The current study utilised a moderate, episodic exposure model in rats to mimic 'special occasion' drinking, which is reported to be common during pregnancy. Our objective was to examine the consequences of this prenatal alcohol exposure on reproductive parameters in female offspring. Pregnant Sprague Dawley rats were treated with either an ethanol gavage (1g EtOH/kg body weight), or an equivalent volume of saline, on embryonic days 13.5 and 14.5 of pregnancy, resulting in a peak blood alcohol concentration of ~0.04%. Neonatal female offspring were examined for molecular markers regulating early follicle numbers in the ovary and unbiased stereology used to quantify primordial and early growing follicle numbers. Puberty onset (age at vaginal opening and first estrous) was measured post-weaning and estrous cycles, reproductive hormones (progesterone and estradiol) and pregnancy success measured in adults (5-6 months of age). We found no evidence that any of these reproductive parameters were significantly altered by PAE in this model. This animal study provides some reassurance for women who may have consumed a small amount of alcohol during their pregnancy. However, previously published effects on offspring metabolism using this model reinforce avoidance of alcohol during pregnancy.In cattle, embryo transfer into the uterine horn contralateral to the corpus luteum results in a higher incidence of pregnancy loss compared to transfer into the ipsilateral horn. We have previously reported temporal changes in the endometrial transcriptome during the estrous cycle which differ between uterine horns. The objective of this study was to compare the transcriptomic response of endometrium from the ipsilateral and contralateral horns to an elongating conceptus. Cross-bred beef heifers (n= 16) were synchronized and either used to generate day 14 conceptuses following the transfer of in vitro-produced blastocysts, or to obtain day 14 endometrial explants. Conceptuses were recovered on day 14 by post-mortem uterine flushing, placed individually on top of explants collected from the ipsilateral (IPSI-D14) or the contralateral (CONTRA-D14) uterine horn of cyclic heifers, and co-cultured for 6 h. The response to a conceptus was markedly different between uterine horns, with 61 and 239 differentially expressed genes (DEGs; false discovery rate less then 0.05) in the ipsilateral and contralateral horns respectively, compared to their controls. Direct comparison between IPSI-D1 and CONTRA-D14 revealed 32 DEGs, including CXCL11, CXCL10, IFIT2, RSAD2 and SAMD9. Gene Ontology analysis of these 32 genes revealed 10 enriched biological processes, mainly related to immune response and response to an external stimulus. These data indicate that the endometrial response to the presence of a conceptus varies between uterine horns in the same uterus and may contribute to the higher incidence of pregnancy loss following embryo transfer to the contralateral horn.Summary A 19-year-old female presented at 25-weeks gestation with pancreatitis. She was found to have significant hypertriglyceridaemia in context of an unconfirmed history of familial hypertriglyceridaemia. This was initially managed with fasting and insulin infusion and she was commenced on conventional interventions to lower triglycerides, including a fat-restricted diet, heparin, marine oil and gemfibrozil. Despite these measures, the triglyceride levels continued to increase as she progressed through the pregnancy, and it was postulated that she had an underlying lipoprotein lipase defect. Therefore, a multidisciplinary decision was made to commence therapeutic plasma exchange to prevent further episodes of pancreatitis. She underwent a total of 13 sessions of plasma exchange, and labour was induced at 37-weeks gestation in which a healthy female infant was delivered. There was a rapid and significant reduction in triglycerides in the 48 h post-delivery. Subsequent genetic testing of hypertriglyceridaemieridaemia rely on the augmentation of lipoprotein lipase (LPL) activity to enhance catabolism of triglyceride-rich lipoproteins. Genetic mutations affecting the LPL gene can lead to severe hypertriglyceridaemia. Therapeutic plasma exchange (TPE) is an effective intervention for the management of severe gestational hypertriglyceridaemia and should be considered in cases where there is an underlying LPL defect. Preconception counselling and discussion regarding contraception is of paramount importance in women with familial hypertriglyceridaemia.Summary Papillary thyroid gland carcinoma is the most common type of malignancy of the endocrine system. selleck chemical Metastases to the pituitary gland have been described as a complication of papillary thyroid cancer in few reported cases since 1965. We report the case of a 68-year-old female patient with a well-differentiated form of thyroid gland cancer. Despite it being the most common malignant cancer of the endocrine system, with its papillary form being one of the two most frequently diagnosed thyroid cancers, the case we present is extremely rare. Sudden cardiac arrest during ventricular fibrillation occurred during hospitalization. Autopsy of the patient revealed papillary carcinoma of the thyroid, follicular variant, with metastasis to the sella turcica, and concomitant sarcoidosis of heart, lung, and mediastinal and hilar lymph nodes. Not only does atypical metastasis make our patient's case most remarkable, but also the postmortem diagnosis of sarcoidosis makes her case particularly unusual. Learning points The goal of presenting this case is to raise awareness of the clinical heterogeneity of papillary cancer and promote early diagnosis of unexpected metastasis and coexisting diseases to improve clinical outcomes. Clinicians must be skeptical. They should not fall into the trap of diagnostic momentum or accept diagnostic labels at face value. Regardless of the potential mechanisms, clinicians should be aware of the possibility of the coexistence of thyroid cancer and sarcoidosis as a differential diagnosis of lymphadenopathy. This case highlights the importance of the diagnostic and therapeutic planning process and raises awareness of the fact that one uncommon disease could be masked by another extremely rare disorder.
