The impact of the COVID-19 pandemic on the Galapagos Islands' seafood system from consumers' perspectives.

The COVID-19 pandemic's early stages severely impacted global fisheries, particularly areas heavily reliant on imported food and tourism like the Galapagos Islands, Ecuador. To contain the spread of the virus, a full lockdown was implemented. However, the collapse of the tourism industry precipitated the worst economic crisis in the history of this multiple-use marine protected area. This paper examines the impact of the pandemic's early stages on consumption patterns and seafood security in the Galapagos from consumers' perspective, drawing on online surveys conducted during the lockdown. Our findings revealed pre-existing seafood insecurity across the archipelago, further exacerbated by the pandemic on the least-populated island. Nevertheless, the seafood system displayed moderated resilience to the pandemic's socioeconomic disruptions. A variety of adaptive responses were adopted by Galapagos residents to cope with the lockdown. Consumers modified their seafood consumption habits, while fishers adapted their harvesting and marketing strategies. Such adaptive responses were shaped by the unique socioeconomic characteristics of each inhabited island and the ability of seafood suppliers to shift from a tourism- and export-oriented to a resident- and domestic-oriented market. This transition has created novel opportunities to foster a systemic transformation of the Galapagos seafood system to enhance its resilience against future crises caused by new pandemics, climate change, or other natural and anthropogenic drivers of change.

Analysis of metals and metalloid in commercial fish species from the Galapagos Marine Reserve: Toxicological and nutritional assessment.

Aquatic pollution derived from metal presence in the Galapagos Islands could affect biodiversity and human health. This research provide a baseline on food safety in commercial fish species of the Galapagos Islands. We sampled muscle tissue of pelagic (Acanthocybium solandri) and demersal (Caulolatilus affinis, Pontinus clemensi, Hyporthodus mystacinus, and Paralabrax albomaculatus) species. Metal and metalloid concentrations per species were analyzed by Inductively Coupled Plasma Optical Spectrometry (ICP-OES). According to the Food and Agriculture Organization (FAO) regulation none of the studied species should be ingested; and according to the European Food Safety Authority (EFSA) regulation, all the studied species were above the Maximum Allowable Concentration (MAC) for Cd. According to EFSA, C. affinis should not be commercialized. Finally, A. solandri, P. clemensi and H. mystacinus do not represent a human health risk since its Margen of Safety (MoS) < 1 for people of up to 100 kg of body weight.

Goals, challenges, and next steps in transdisciplinary fisheries research: perspectives and experiences from early-career researchers.

Fisheries are highly complex social-ecological systems that often face 'wicked' problems from unsustainable resource management to climate change. Addressing these challenges requires transdisciplinary approaches that integrate perspectives across scientific disciplines and knowledge systems. Despite widespread calls for transdisciplinary fisheries research (TFR), there are still limitations in personal and institutional capacity to conduct and support this work to the highest potential. The viewpoints of early career researchers (ECRs) in this field can illuminate challenges and promote systemic change within fisheries research. This paper presents the perspectives of ECRs from across the globe, gathered through a virtual workshop held during the 2021 World Fisheries Congress, on goals, challenges, and future potential for TFR. Big picture goals for TFR were guided by principles of co-production and included (i) integrating transdisciplinary thinking at all stages of the research process, (ii) ensuring that research is inclusive and equitable, (iii) co-creating knowledge that is credible, relevant, actionable, and impactful, and (iv) consistently communicating with partners. Institutional inertia, lack of recognition of the extra time and labour required for TFR, and lack of skill development opportunities were identified as three key barriers in conducting TFR. Several critical actions were identified to help ECRs, established researchers, and institutions reach these goals. We encourage ECRs to form peer-mentorship networks to guide each other along the way. We suggest that established researchers ensure consistent mentorship while also giving space to ECR voices. Actions for institutions include retooling education programs, developing and implementing new metrics of impact, and critically examining individualism and privilege in academia. We suggest that the opportunities and actions identified here, if widely embraced now, can enable research that addresses complex challenges facing fishery systems contributing to a healthier future for fish and humans alike.

Early life history of the middling thread herring (Opisthonema medirastre) in the central Galápagos Islands.

The authors estimated life-history parameters of a clupeid forage fish, Opisthonema medirastre, by sampling juveniles over the course of a year in the central region of the Galápagos Islands, Ecuador. They collected 160 juveniles on the south coast of Santa Cruz Island during the wet/warm season that were 16-48 mm standard length, were 30-88 days old, had hatched at the beginning of the wet/warm season and had grown at 0.4 mm day-1 . The results suggest that in Galápagos, O. medirastre reproduce during the wet/warm season mostly under neutral ENSO conditions.

Living conditions, seroprevalence and symptoms of COVID-19 in slums in the Metropolitan Region of Vitória (Espírito Santo).

OBJECTIVES: to estimate the prevalence of SARS-CoV-2 infection in residents of the Greater Vitória region living in subnormal and non-subnormal agglomerates, and to compare sociodemographic and clinical characteristics of total residents (infected and not infected with SARS-CoV-2) between them. METHODS: Population-based prevalence study conducted by serological testing in 2020, with a study unit in households in Greater Vitória, grouped into census tracts classified as sub-normal agglomerates and non-sub-normal agglomerates. The two groups were compared in terms of prevalence and associated factors. The significance level adopted was 5%. RESULTS: The prevalence found in the sub-normal clusters was 12.05% (95%CI 9.59-14.50), and in the non-sub-normal clusters 10.23% (95%CI 7.97-12.50) this difference was not statistically significant (p = 0.273). Comparing the sociodemographic characteristics, more people who declare themselves to be of mixed race were found in the sub-normal clusters, a higher percentage of illiterates and people with only elementary education, greater number of residents per household, longer stay in public transportation, sharing a bathroom with another household, fewer bedrooms per residence and higher frequency of irregular water supply when compared to non-sub-normal clusters (p < 0.05). CONCLUSIONS: The epidemiological characteristics of sub-normal clusters' residents show the social inequalities that can hinder control measures in a pandemic situation.

COVID-19 in children, adolescents and young adults: a cross-sectional study in Espírito Santo, Brazil, 2020. / COVID-19 em crianças, adolescentes e jovens: estudo transversal no Espírito Santo, 2020.

OBJECTIVE: To analyze self-reported sociodemographic and clinical characteristics among individuals aged 2 to 22 years and possible associations with SARS-CoV-2 infection in Espírito Santo, Brazil. METHODS: This was a serial cross-sectional population-based study carried out from May to June 2020. The COVID-19 positivity rate was assessed by serological testing, and associated factors were assessed using Pearson's chi-square test (5% significance level). RESULTS: Among 1,693 individuals aged 2 to 22 years, 6.1% tested positive for COVID-19 and, among these, 35.5% did not present any symptoms. Differences were identified between positive and negative cases regarding the number of symptoms (p-value=0.001).Coughing was reported by 40.4% of positive individuals. Only 14.3% sought health care, namely 29.8% among those who tested positive and 13.3% among those who tested negative (p-value=0.001). CONCLUSION: The percentage of asymptomatic patients can impact the COVID-19 transmission chain in schools and fuel outbreaks of the disease in schools.

Metal and metalloids concentration in Galapagos fish liver and gonad tissues.

The Galapagos Islands are one of the best-preserved archipelagos in the world. We sampled individuals of six demersal and three pelagic species. The metal concentration of liver and gonad tissues were analyzed by Inductively Coupled Plasma Optical Spectrometry. Findings suggest none of the pelagic species showed metallic concentrations that could pose a risk to their health or reproductive capacity. S. violacea and P. clemensi Zn levels were higher in liver than in gonads, indicating that these species could be in their reproduction period. Zn risk toxicity for the study species is negligible. High concentrations of Cd were found in the liver of C. princeps, C. affinis and P. albomaculatus which could cause morphological and physiological alterations. We hypothesize that the high metal concentrations found in the demersal species could come from the volcanism of the islands, since no major sources of anthropogenic metal contamination can be found in the archipelago.

Metals in commercial fish in the Galapagos Marine Reserve: Contribution to food security and toxic risk assessment.

Metal pollution in the marine environment can damage places with exceptional biodiversity such as the Galapagos Islands. For this reason, it is important to evaluate the toxic risk from metals derived from fish consumption and to perform a nutritional assessment. We sampled 20 individuals of demersal (Caulolatilus princeps and Mycteroperca olfax) and pelagic (Thunnus albacares and Seriolella violacea) species. The levels of the toxic elements (Al, B, Ba, Cd, Ni, Pb and Sr), and the macroelements, microelements and trace elements (Ca, Cr, Fe, K, Li, Mn, Mo, Mg, Na, V and Zn) of species muscle tissue were analyzed by Inductively Coupled Plasma Optical Spectrometry (ICP-OES). Demersal species have higher concentrations of Cr, K, Mg and Mo; while pelagic species have higher levels of Zn. M. olfax could potentially cause Cd toxicity so it is recommended not to ingest more than 86 and 73 g of this species (i.e. roughly, one serving) per week for men and women, respectively. None of the species could be marketed in Europe and the USA due to Cd level exceed the allowed limits by EFSA and FAO. Furthermore, the dietary intake of C. princeps is recommended due to its high concentration of Ca, Na, K, Mg and Cr, while T. albacares is recommended for people with Zn deficiency. However, due to the Cd level in C. princeps it is not recommended to ingest more than five servings per week. We attribute the source of metals in the studied fish from the volcanic origin of the islands rather than from human pollution. This is the first study that thoroughly estimate concentration of metals in commercial fish species and its contribution to food security in the Galapagos.

VALIDATION OF A NEW WATER-PERFUSED HIGH-RESOLUTION MANOMETRY SYSTEM.

BACKGROUND: Water-perfused high resolution manometry system. High-resolution manometry is more costly but clinically superior to conventional manometry. Water-perfused systems may decrease costs, but it is unclear if they are as reliable as solid-state systems, and reference values are interchangeable. AIM: To validate normal values for a new water-perfusion high-resolution manometry system. METHODS: Normative values for a 24-sensors water perfused high-resolution manometry system were validated by studying 225 individuals who underwent high resolution manometry for clinical complaints. Patients were divided in four groups: group 1 - gastroesophageal reflux disease; group 2 - achalasia; group 3 - systemic diseases with possible esophageal manifestation; and group 4 - dysphagia. RESULTS: In group 1, a hypotonic lower esophageal sphincter was found in 49% of individuals with positive 24 h pH monitoring, and in 28% in pH-negative individuals. In groups 2 and 3, aperistalsis was found in all individuals. In group 4, only one patient (14%) had normal high-resolution manometry. CONCLUSIONS: The normal values determined for this low-cost water-perfused HRM system with unique peristaltic pump and helicoidal sensor distribution are discriminatory of most abnormalities of esophageal motility seen in clinical practice.

Resultados: A prevalência encontrada em não aglomerados subnormais foi 12,05% (IC95% 9,59-14,50) e no grupo aglomerados não subnormais foi 10,23% (IC95% 7,97-12,50), e essa diferença não foi estatisticamente significante (p = 0,273). Comparando-se as características sociodemográficas, encontraram-se nos aglomerados subnormais mais pessoas que se autodeclaram da raça/cor parda, percentual maior de analfabetos e de pessoas apenas com ensino fundamental, maior número de moradores por domicílio, maior permanência em transporte coletivo, compartilhamento de banheiro com outro domicílio, menos dormitórios por residência e maior frequência de abastecimento irregular de água quando comparado aos aglomerados não subnormais (p<0,05). Conclusões: As características epidemiológicas dos moradores de aglomerados subnormais evidenciam as desigualdades sociais que podem dificultar as medidas de controle em uma situação de pandemia.

Validation of a new water-perfused high-resolution manometry system / Validação de um novo sistema de manometria de alta resolução por perfusão de água

ABSTRACT Background: High-resolution manometry is more costly but clinically superior to conventional manometry. Water-perfused systems may decrease costs, but it is unclear if they are as reliable as solid-state systems, and reference values are interchangeable. Aim: To validate normal values for a new water-perfusion high-resolution manometry system. Methods: Normative values for a 24-sensors water perfused high-resolution manometry system were validated by studying 225 individuals who underwent high resolution manometry for clinical complaints. Patients were divided in four groups: group 1 - gastroesophageal reflux disease; group 2 - achalasia; group 3 - systemic diseases with possible esophageal manifestation; and group 4 - dysphagia. Results: In group 1, a hypotonic lower esophageal sphincter was found in 49% of individuals with positive 24 h pH monitoring, and in 28% in pH-negative individuals. In groups 2 and 3, aperistalsis was found in all individuals. In group 4, only one patient (14%) had normal high-resolution manometry. Conclusions: The normal values determined for this low-cost water-perfused HRM system with unique peristaltic pump and helicoidal sensor distribution are discriminatory of most abnormalities of esophageal motility seen in clinical practice.

RESUMO Racional: A manometria de alta resolução é mais custosa, porém clinicamente superior à manometria convencional. Sistemas por perfusão de água podem ter custo diminuído, mas não é certo se são tão eficazes quanto aos sistemas de estado sólido e se os valores de referência são intercambiáveis. Objetivo: Este estudo visa validar valores de normalidade para um novo sistema por perfusão de água. Método: Valores de normalidade para um sistema de manometria de alta resolução de 24 sensores por perfusão de água foram validados estudando 225 indivíduos submetidos à manometria de alta resolução por queixas clínicas. Pacientes foram divididos em quatro grupos: grupo 1 - doença do refluxo gastroesofágico; grupo 2 - acalasia; grupo 3 - doenças sistêmicas com possível doenças sistêmicas com comprometimento esofágico; e grupo 4 - pacientes com disfagia. Resultado: No grupo 1, esfíncter esofagiano inferior hipotônico foi encontrado em 49% dos indivíduos com pHmetria positiva e 28% daqueles com pHmetria negativa. Nos grupos 2 e 3, aperistalse foi encontrada em todos indivíduos. No grupo 4, somente um paciente (14%) tinha manometria normal. Conclusão: Os valores de normalidade definidos para este sistema de manometria de alta resolução por perfusão de água são discriminatórios da maioria das anormalidades da motilidade esofágica vistas na prática clínica.

Uso de medicamentos potencialmente inapropriados para pessoas idosas em uma associação de aposentados / Use of potentially inappropriate medications by old people in a retiree's association

Resumo Objetivo verificar a prevalência da utilização de medicamentos potencialmente inapropriados e polifarmácia pela pessoa idosa. Método estudo observacional, com recorte transversal, analítico, quantitativo, de base populacional em uma associação de aposentados. Os dados foram coletados a partir de questionário estruturado, criado pelos próprios pesquisadores e aplicado em domicílio a uma amostra de 203 pessoas idosas. Resultados a idade média dos participantes foi de 73,1+8,13 anos (IC90%: 72,2-74,0), variando de 60 a 95 anos. A maioria declarou-se casado 54,2% (n=110/203), com ensino fundamental 71,4% (n=145/203), e renda familiar entre 2 e 4 salários mínimos 49,3% (n=100/203). As comorbidades mais encontradas foram: hipertensão arterial sistêmica 67,5% (n=137/203), artrite/artrose 30,5% (n=62/203), osteoporose 20,2% (n=41/203), entre outras. Quanto ao uso de medicamentos contínuos e eventuais, constatou-se uma mediana de 6 medicamentos utilizados pelos participantes, sendo 1 o número mínimo e 18 o número máximo. Houve polifarmácia em 64,5% (n=131/203) dos idosos e o uso de medicamentos potencialmente inapropriados em 78,8% (n=160/203). Quanto à utilização de polifarmácia, foi verificado associação significativa com: sexo feminino (p=0,004); e ter baixa escolaridade (p=0,017), e estado civil solteiro (0,027). Conclusão no âmbito da farmacoepidemiologia, o conhecimento dos fatores associados à utilização de medicamentos, como os identificados neste estudo, pode ser útil para alertar os prescritores e demais profissionais da saúde quanto à importância de identificar e monitorar os grupos mais vulneráveis, como por exemplo, as pessoas idosas.

Abstract Objective to verify the prevalence of the use of potentially inappropriate medications and polypharmacy by old people. Methods observational, cross-sectional, analytical, quantitative, population-based study in a retirees association. The data were collected from a questionnaire structured and created by the researchers and applied to the household. The association has 2,902 associates and underwent a stratified proportional sampling by gender, delimiting a sample of 203 old people, being 129 women and 76 men. Results the mean age of study participants was 73.1+8.13 years (90%CI:72.2-74.0), ranging from 60 to 95 years. The majority declared being married 110 (54.2%), with elementary education 145 (71.4%) and family income between 2 and 4 minimum wages 100 (49.3%). The most frequent comorbidities were: diabetes mellitus 33 (16.26%), systemic arterial hypertension 137 (67.49%), hypercholesterolemia 24 (11.8%), arthritis/arthrosis 62 (30.54%), osteoporosis 41 (20.2%), depression 27 (13.3%), among others with non-significant values. When analyzing the use of continuous and occasional medications, a median of 6 drugs used by participants was found, with 1 being the minimum number and 18 being the maximum number. The use of polypharmacy was identified in 131 (64.5%) old people and the use of potentially inappropriate medications in 160 (78.8%). Regarding the use of polypharmacy, a significant association was found with: female gender (p=0.004); and having low education (p=0.017), and single marital status (0.027). Conclusions in the context of pharmacoepidemiology, knowledge of the factors associated with the use of medicines may be useful to alert health professionals to the importance of identifying and monitoring the most vulnerable groups of old people in order to avoid the use of potentially inappropriate medications for the age group.
