RESUMEN
The purpose of this study was to determine the pregnancy rate in the double sequential transfer of embryos on both day 3 and day 5 compared to day 5 alone, in in vitro fertilization-embryo transfer (IVF/ET) in patients with the three repeated consecutive IVF failures. In this controlled trial, women scheduled for IVF/ET with the three repeated consecutive IVF failures were randomized to either sequential transfer of embryos on day 2 and on day 5 after ovum pick-up (group 1, n = 60) or blastocyst ET on day 5 (group 2, n = 60) as a control group. The primary outcome measures were the chemical and clinical pregnancy rate. Baseline and cycle characteristics were comparable in both groups. Chemical and clinical pregnancy rate was similar in the sequential ET group (40%) compared to the day 5 of ET group (38.3%) (p value = .85). It seems that the double ET does not increase the chance of pregnancy rate compared to blastocyst ET on day 5 in the patients with the three repeated IVF-ET failures.

OBJECTIVE: To describe the local experience of adult patients presenting with cannabinoid hyperemesis syndrome (CHS) to an urban ED in the outer northern suburbs of Melbourne. METHODS: Retrospective chart review of adult patients presenting to the ED with a documented history of CHS or equivalent terminology from January 2015 to January 2021. Age, sex, cannabis use, clinical features, pathology results, imaging and symptomatic management were examined as well as outcomes regarding disposition, representation, morbidity and mortality. RESULTS: One hundred and forty-two adult presentations were included. Sixty-seven were unique presentations and 29 were patients who represented during the study period. Most represented within 3 months (37.8%) and most represented at least twice. Males were overrepresented (68.7%). Patients were young (median age 31 years, interquartile range 23-35 years) and all had a history of regular cannabis use (usually daily). Cyclical nausea and/or vomiting was the most common clinical feature compared to others in previously reported diagnostic criteria. Patients typically had elevated white cell counts with associated neutrophilia (75.8%) and mild hypokalaemia (57.9%). Lipase was not elevated, and C-reactive protein was typically less than 50 mmol/L (98.2%). Imaging was not commonly performed but largely normal. Treatment was supportive with anti-emetic use, intravenous fluids and analgesia. There were no deaths or admissions to intensive care. CONCLUSIONS: Cyclical nausea and vomiting was the most common feature observed in this cohort compared to other clinical features reported in prior studies. Serum lipase was normal and C-reactive protein only mildly elevated. Prospective studies are required to further assess these findings.
