    Comparable information on the status of natural resources across large geographic and human impact scales provides invaluable context to ecosystem-based management and insights into processes driving differences among areas. Data on fish assemblages at 39 US flag coral reef-areas distributed across the Pacific are presented. Total reef fish biomass varied by more than an order of magnitude: lowest at densely-populated islands and highest on reefs distant from human populations. Remote reefs (<50 people within 100 km) averaged ∼4 times the biomass of "all fishes" and 15 times the biomass of piscivores compared to reefs near populated areas. Greatest within-archipelagic differences were found in Hawaiian and Mariana Archipelagos, where differences were consistent with, but likely not exclusively driven by, higher fishing pressure around populated areas. Results highlight the importance of the extremely remote reefs now contained within the system of Pacific Marine National Monuments as ecological reference areas

    Environmental Factors Affecting Large-Bodied Coral Reef Fish Assemblages in the Mariana Archipelago

    Large-bodied reef fishes represent an economically and ecologically important segment of the coral reef fish assemblage. Many of these individuals supply the bulk of the reproductive output for their population and have a disproportionate effect on their environment (e.g. as apex predators or bioeroding herbivores). Large-bodied reef fishes also tend to be at greatest risk of overfishing, and their loss can result in a myriad of either cascading (direct) or indirect trophic and other effects. While many studies have investigated habitat characteristics affecting populations of small-bodied reef fishes, few have explored the relationship between large-bodied species and their environment. Here, we describe the distribution of the large-bodied reef fishes in the Mariana Archipelago with an emphasis on the environmental factors associated with their distribution. Of the factors considered in this study, a negative association with human population density showed the highest relative influence on the distribution of large-bodied reef fishes; however, depth, water temperature, and distance to deep water also were important. These findings provide new information on the ecology of large-bodied reef fishes can inform discussions concerning essential fish habitat and ecosystem-based management for these species and highlight important knowledge gaps worthy of additional research

    Molnupiravir plus usual care versus usual care alone as early treatment for adults with COVID-19 at increased risk of adverse outcomes (PANORAMIC): an open-label, platform-adaptive randomised controlled trial

    Background: The safety, effectiveness, and cost-effectiveness of molnupiravir, an oral antiviral medication for SARS-CoV-2, has not been established in vaccinated patients in the community at increased risk of morbidity and mortality from COVID-19. We aimed to establish whether the addition of molnupiravir to usual care reduced hospital admissions and deaths associated with COVID-19 in this population. Methods: PANORAMIC was a UK-based, national, multicentre, open-label, multigroup, prospective, platform adaptive randomised controlled trial. Eligible participants were aged 50 years or olderβ€”or aged 18 years or older with relevant comorbiditiesβ€”and had been unwell with confirmed COVID-19 for 5 days or fewer in the community. Participants were randomly assigned (1:1) to receive 800 mg molnupiravir twice daily for 5 days plus usual care or usual care only. A secure, web-based system (Spinnaker) was used for randomisation, which was stratified by age (<50 years vs β‰₯50 years) and vaccination status (yes vs no). COVID-19 outcomes were tracked via a self-completed online daily diary for 28 days after randomisation. The primary outcome was all-cause hospitalisation or death within 28 days of randomisation, which was analysed using Bayesian models in all eligible participants who were randomly assigned. This trial is registered with ISRCTN, number 30448031. Findings: Between Dec 8, 2021, and April 27, 2022, 26 411 participants were randomly assigned, 12 821 to molnupiravir plus usual care, 12 962 to usual care alone, and 628 to other treatment groups (which will be reported separately). 12 529 participants from the molnupiravir plus usual care group, and 12 525 from the usual care group were included in the primary analysis population. The mean age of the population was 56Β·6 years (SD 12Β·6), and 24 290 (94%) of 25 708 participants had had at least three doses of a SARS-CoV-2 vaccine. Hospitalisations or deaths were recorded in 105 (1%) of 12 529 participants in the molnupiravir plus usual care group versus 98 (1%) of 12 525 in the usual care group (adjusted odds ratio 1Β·06 [95% Bayesian credible interval 0Β·81–1Β·41]; probability of superiority 0Β·33). There was no evidence of treatment interaction between subgroups. Serious adverse events were recorded for 50 (0Β·4%) of 12 774 participants in the molnupiravir plus usual care group and for 45 (0Β·3%) of 12 934 in the usual care group. None of these events were judged to be related to molnupiravir. Interpretation: Molnupiravir did not reduce the frequency of COVID-19-associated hospitalisations or death among high-risk vaccinated adults in the community

    Emergency department physician training in Jamaica: a national public hospital survey

    <p>Abstract</p> <p>Background</p> <p>Emergency Department (ED) medical officers are often the first medical responders to emergencies in Jamaica because pre-hospital emergency response services are not universally available. Over the past decade, several new ED training opportunities have been introduced locally. Their precise impact on the health care system in Jamaica has not yet been evaluated. We sought to determine the level of training, qualifications and experience of medical officers employed in public hospital EDs across the nation.</p> <p>Methods</p> <p>A database of all medical officers employed in public hospital EDs was created from records maintained by the Ministry of Health in Jamaica. A specially designed questionnaire was administered to all medical officers in this database. Data was analyzed using SPSS Version 10.0.</p> <p>Results</p> <p>There were 160 ED medical officers across Jamaica, of which 47.5% were males and the mean age was 32.3 years (SD +/- 7.1; Range 23–57). These physicians were employed in the EDs for a mean of 2.2 years (SD +/- 2.5; Range 0–15; Median 2.5) and were recent graduates of medical schools (Mean 5.1; SD +/- 5.9; Median 3 years).</p> <p>Only 5.5% of the medical officers had specialist qualifications (grade III/IV), 12.8% were grade II medical officers and 80.5% were grade I house officers or interns. The majority of medical officers had no additional training qualifications: 20.9% were exposed to post-graduate training, 27.9% had current ACLS certification and 10.3% had current ATLS certification.</p> <p>Conclusion</p> <p>The majority of medical officers in public hospital EDs across Jamaica are relatively inexperienced and inadequately trained. Consultant supervision is not available in most public hospital EDs. With the injury epidemic that exists in Jamaica, it is logical that increased training opportunities and resources are required to meet the needs of the population.</p
