Large floating abandoned, lost or discarded fishing gear (ALDFG) is frequent marine pollution in the Hawaiian Islands and Palmyra Atoll.

Abandoned, lost, or discarded fishing gear (ALDFG) is a major source of marine debris with significant ecological and economic consequences. We documented the frequency, types, sizes, and impacts of ALDFG recovered from Hawai'i and Palmyra Atoll in the Central North Pacific Ocean (CNPO) from 2009 to 2021. A total of 253 events weighing 15 metric tons were recovered, including 120 drifting fish aggregating device (dFAD) components, 61 conglomerates, fewer distinct nets, lines, buoys, and unique gear.

Intestinal pneumatosis: a rare and misdiagnosed entity.

Intestinal pneumatosis is a rare entity, usually found incidentally, and in most cases asymptomatic. We present the case of an 84-year-old man who underwent colonoscopy for adenomatous polyps surveillance and presented typical endoscopic images of intestinal pneumatosis. Some of the most important aspects of the disease are highlighted and even if the endoscopic image is quite impressive, conservative management is the treatment of choice.

Strength and Comprehensiveness of Drinking Water Language in California School District Wellness Policies.

Objective(s): Assess the quality of water language in California school district wellness policies and examine how language quality relates to school drinking water access.

Design: Cross-sectional study.

Participants: Random sample of 240 schools selected from all California public schools, stratified by geography and grades served.

A cluster-randomized controlled trial of an elementary school drinking water access and promotion intervention: Rationale, study design, and protocol.

Introduction: Promoting water consumption among children in schools is a promising intervention to reduce sugar-sweetened beverage (SSB) intake and achieve healthful weight. To date, no studies in the United States have examined how a school-based water access and promotion intervention affects students' beverage and food intake both in and out of school and weight gain over time. The Water First trial is intended to evaluate these interventions.

Drinking water access in California schools: Room for improvement following implementation of school water policies.

This study aims to investigate how access to free drinking water in California public schools changed after implementation of 2010 federal and state school water policies. Repeated cross-sectional surveys were conducted with administrators in a random sample of California public schools, stratified by school type and urban-centric geography, from 2010 to 2011 (n = 240) and from 2016 to 2018 (n = 240). Surveys assessed excellence in drinking water access, defined as 1) providing water in 4 of 5 key school locations, 2) having a high density of free water available, 3) providing water via a non-fountain source, 4) providing water that is perceived as safe, and 5) offering water sources that are reported as clean and functioning.

Towards acoustic discrimination of tropical tuna associated with Fish Aggregating Devices.

Tropical tuna support some of the largest and most valuable artisanal and industrial fisheries worldwide, conducted to a large degree with Fish Aggregating Devices (FADs). Yellowfin, bigeye and skipjack are the main tuna species found in mixed aggregations around FADs and they are simultaneously encircled by the purse seining operation. One of the key challenges that purse seine fleets fishing with drifting FADs face in all oceans is to be able to target species in healthy condition such as skipjack, while reducing impacts on bigeye and yellowfin in areas where there is a need to reduce fishing pressure on these species.

Aggregation process of drifting fish aggregating devices (DFADs) in the Western Indian Ocean: Who arrives first, tuna or non-tuna species?

Floating objects drifting in the surface of tropical waters, also known as drifting fish aggregating devices (DFADs), attract hundreds of marine species, including tuna and non-tuna species. Industrial tropical purse seiners have been increasingly deploying artificial man-made DFADs equipped with satellite linked echo-sounder buoys, which provide fishers with information on the accurate geo-location of the object and rough estimates of the biomass aggregated underneath, to facilitate the catch of tuna. Although several hypotheses are under consideration to explain the aggregation and retention processes of pelagic species around DFADs, the reasons driving this associative behavior are uncertain.

Lunch at the library: examination of a community-based approach to addressing summer food insecurity.

Objective: To examine a library-based approach to addressing food insecurity through a child and adult summer meal programme. The study examines: (i) risk of household food insecurity among participants; (ii) perspectives on the library meal programme; and (iii) barriers to utilizing other community food resources.

Design: Quantitative surveys with adult participants and qualitative semi-structured interviews with a sub-sample of adult participants.
