ABSTRACT

Objectives. To assess the health impact of Hurricane Irma and Hurricane Maria on St Thomas, US Virgin Islands.Methods. We collected data from interviews conducted 6 and 9 months after the hurricanes, a review of 597 randomly selected emergency department (ED) encounters, and administrative records from 10 716 ED visits 3 months before, between, and 3 months after the hurricanes.Results. Informants described damaged hospital infrastructure, including flooding, structural damage, and lost staff. The greatest public health impact was on the elderly and persons with chronic diseases. In the setting of loss of the electronic medical record system, ED chart reviews were limited by problems with missing data. ED administrative data demonstrated that posthurricane patients, compared with prehurricane patients, were older and had less severe complaints. There was a significant increase in patients being seen for diabetes-related and respiratory complaints, especially asthma. Suboptimal recordkeeping for medical evacuees limited the ability to assess outcomes for patients with severe illnesses.Conclusions. Hurricanes Irma and Maria caused major disruptions to health care on St Thomas. Emphasis should be given to building a resilient health care system that will optimally respond to future hurricanes.

ABSTRACT

BACKGROUND: It has been demonstrated that human milk osmolality (Mosm) is regulated within an established range, typically 290 to 300 mOsm/kg, and appears to be resistant to effects of maternal dehydration, as refl ected by high urinary osmolality (Uosm). OBJECTIVE: To determine the degree of association between Mosm and Uosm at a common point in time, as well as the reproducibility of both measures over a one-week interval of sampling. METHODS: Mosm and Uosm were measured with a Vogel Löser 450 osmometer on samples of the respective biological fluids collected concurrently in 31 lactating women, with infants aged between 30 and 340 days. In the first 15 women recruited, collections were repeated 7 days after the initial ones. RESULTS: The median Mosm for the 46 samples collected was 308 mOsm/kg with a range from 288 to 448 mOsm/kg. The corresponding values for Uosm were 598 mOsm/kg with a range from 93 to 1,678 mOsm/kg. The Spearman rank-order correlation coeffi cient for within-individual association of Mosm and Uosm was r = 0.214 (p = 0.153). The median Mosm for the 15 repeat-subjects was 309 mOsm/kg on both occasions, with a within-individual Spearman coeffi cient of r = 0.326 (p = 0.118). By contrast, for the Uosm, the within-subject association was much stronger, with r = 0.699 (p = 0.002). CONCLUSIONS: The osmometry technique proved to be a highly stable and reproducible measurement technique. Mosm and Uosm are not significantly associated at a point in time. Intra-subject Mosm varies more across time than intra-subject Uosm.
