Objective:
Alcohol is a major public health issue and the ACEM funds regular 'snapshot' surveys of the prevalence of alcohol-related presentations in EDs. The present study uses these data to investigate ED occupancy and alcohol- and methamphetamine-related presentations at the time of the COVID-19 pandemic.
Methods:
Survey-based point prevalence study of EDs in Australia and New Zealand conducted at 02:00 hours local time on the Saturday of the weekend before Christmas in 2019-2022. Primary outcomes were ED occupancy, the number of alcohol-related presentations and methamphetamine-related presentations in each ED at the time of survey.
Results:
Seventy eight of a possible 152 hospitals answered all four surveys (51%, 95% confidence interval 43-59, individual yearly response rates ranged from 70.5% to 83.3%). The mean number of alcohol-related presentations in EDs at the snapshot time was 4.2 (95% confidence interval 3.2-5.2) in the 2019 survey and 3.8 (3.1-4.6) in 2022 with no significant variation over time. There was also no change in methamphetamine-related presentations which occurred at a lower level. There was a major increase in reported total ED occupancy - from 31.4 to 43.5 in Australia (P < 0.0001, paired t test) and from 22.8 to 38.7 in New Zealand (P = 0.0001). Subgroup analysis showed that both the number being treated and the number waiting to be seen increased, with little change in the number in observation units.
Conclusions:
The present study demonstrates that the COVID-19 pandemic did not affect summer alcohol-related ED presentations in Australasia but was associated with an unsustainable increase in ED crowding.

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
