Methylmercury contamination in Mediterranean seafood: Exposure assessment and cost of illness implications.

Methylmercury (MeHg) is a widespread contaminant that bioaccumulates in marine food webs, including those in the Mediterranean sea. It poses serious health risks, especially to developing infants and children, where exposure can cause neurological damage and developmental delays. In addition to health concerns, high MeHg levels in seafood can lead to economic losses through cognitive impairments that reduce productivity.

How human health and well-being depends on healthy marine habitats in the Mediterranean: A review.

Human health and well-being, and how they are affected by terrestrial and freshwater ecosystems have been the subject of numerous studies. In contrast, there are very few such studies relating to marine ecosystems. Here, in the context of the Mediterranean Sea, we assess evidence of the broad interplay of relationships between marine habitats and human health and well-being.

Blue prescription: A pilot study of health benefits for oncological patients of a short program of activities involving the sea.

Performing outdoor activities in blue spaces can help improve human health and mental well-being by reducing stress and promoting social relationships. The number of people surviving cancer has increased globally to experience this disease as a life-changing and chronic condition with physical and psychosocial symptoms that have negative impacts on their quality of life. While there has been a growth of programs in green spaces to meet the needs of cancer patients, such as follow-up post-treatment care, support groups and physical activity programs, very few studies have examined the effects of activities involving the sea for the health and well-being of oncology patients.

A study of trophic structure, physiological condition and mercury biomagnification in swordfish (Xiphias gladius): Evidence of unfavourable conditions for the swordfish population in the Western Mediterranean.

Studies integrating trophic ecology, physiological condition and accumulation of heavy metals in top predators, such as swordfish, are needed to better understand the links between them and the risk to humans associated with consumption of these fish. This research focuses on the swordfish of the Catalan Sea and follows a multi method approach that considers their diet, their liver lipid content, and mercury accumulation in their bodies as well as in their prey. The aim is to highlight the links between trophic ecology, physiology (fish condition), and eco-toxicology.

Unravelling the ecological impacts of large-scale offshore wind farms in the Mediterranean Sea.

The need for alternative energy systems like offshore wind power to move towards the Green Deal objectives is undeniable. However, it is also increasingly clear that biodiversity loss and climate change are interconnected issues that must be tackled in unison. In this paper we highlight that offshore wind farms (OWF) in the Mediterranean Sea (MS) pose serious environmental risks to the seabed and the biodiversity of many areas due to the particular ecological and socioeconomic characteristics and vulnerability of this semi-enclosed sea.

Environmental and human health impacts of cruise tourism: A review.

The intensive growth of cruise tourism worldwide during recent decades is leading to growing concerns over the sector's global environmental and health impacts. This review combines for the first time various sources of information to estimate the magnitude of the cruise industry's environmental and public health footprints. This research shows that cruising, despite technical advances and some surveillance programmes, remains a major source of air, water (fresh and marine) and land pollution affecting fragile habitats, areas and species, and a potential source of physical and mental human health risks.

The Bioactive Potential of Trawl Discard: Case Study from a Crinoid Bed Off Blanes (North-Western Mediterranean).

Although knowledge of the bioactive compounds produced by species inhabiting coastal waters is increasing, little is known about the bioactive potential produced by marine species occupying deeper habitats with high biodiversity and productivity. Here, we investigate about the bioactive potential of molecules produced by species that inhabit the crinoid beds, a poorly known essential fish habitat affected by trawling, wherein large amounts of commercial and noncommercial species are discarded. Based on a trawl survey conducted in 2019, 14% of the 64 species discarded on crinoid beds produce molecules with some type of bioactive potential, including; soft corals (); tunicates (); bony fish, such as horse mackerel (); European hake (); and chondrichthyans, such as small-spotted catshark ().

Fatty acid composition and parasitism of European sardine () and anchovy () populations in the northern Catalan Sea in the context of changing environmental conditions.

The status of sardine and anchovy populations in the northern Mediterranean Sea has been declining in recent decades. In this study, fatty acids and parasitism at different reproductive and feeding stages in these two species were assessed using specimens caught along the northern Catalan coast, in order to assess the links between lipid dynamics, reproduction and feeding in these two species and to contribute towards an explanation of the potential causes of the current poor situation of the stocks. The results support the use of fatty acid levels as indicators of the body condition of sardine and anchovy at different reproductive and feeding stages, as well as that of the pelagic environmental conditions.

Benefits of Outdoor Sports in Blue Spaces. The Case of School Nautical Activities in Viana do Castelo.

Participating in outdoor sports in blue spaces is recognized to produce a range of significant social benefits. This case study empirically analyzes the social benefits associated with the School Nautical Activities project carried out in Viana do Castelo (Portugal) in school-age children and adolescents. It consisted of a 4 year program in which scholars took part in nautical activities (surfing, rowing, sailing, and canoeing) in blue spaces once a week during a semester as a part of their physical education course.

The Beneficial Effects of Short-Term Exposure to Scuba Diving on Human Mental Health.

Exposure to outdoor blue spaces can help improve human health by reducing stress, promoting social relationships, and physical activity. While most studies have focused on the adverse health effects of scuba diving, very few have assessed its health benefits. Moreover, when scuba diving is done in large groups with no diving instructor or pre-dive briefing, negative environmental impacts are generated and negative impacts on human health may also occur due to overcrowding, which may create stress.

The Roses Ocean and Human Health Chair: A New Way to Engage the Public in Oceans and Human Health Challenges.

Involving and engaging stakeholders is crucial for studying and managing the complex interactions between marine ecosystems and human health and wellbeing. The Oceans and Human Health Chair was founded in the town of Roses (Catalonia, Spain, NW Mediterranean) in 2018, the fruit of a regional partnership between various stakeholders, and for the purpose of leading the way to better health and wellbeing through ocean research and conservation. The Chair is located in an area of the Mediterranean with a notable fishing, tourist, and seafaring tradition and is close to a marine reserve, providing the opportunity to observe diverse environmental conditions and coastal and maritime activities.

Twilight activity patterns and angling vulnerability of yellowmouth barracuda (Sphyraena viridensis Cuvier, 1829), a range-expanding thermophilic fish.

Among the thermophilic fishes that have become established in the north-western Mediterranean as a consequence of sea warming, the yellowmouth barracuda (Sphyraena viridensis Cuvier, 1829) appears to be one of the most successful and abundant in the coastal rocky environment, having increasingly become the object of recreational and commercial exploitation in the study area. Lure-fishing sessions were carried out from May 2016 to November 2018 in the Catalan Sea (NE Spain) at dawn and dusk, with the aim of providing new insight into the behavioural, spatial and feeding ecology and vulnerability to angling of this poorly known species. Generalized mixed-effects linear models showed that S.

The poor health of deep-water species in the context of fishing activity and a warming climate: will populations of Molva species rebuild or collapse?

Many deep-water fish populations, being K-selected species, have little resilience to overexploitation and may be at serious risk of depletion as a consequence. Sea warming represents an additional threat. In this study, the condition, or health, of several populations of common ling (Molva molva), blue ling (Molva dypterygia) and Mediterranean or Spanish ling (Molva macrophthalma) inhabiting different areas in the North Atlantic and the Mediterranean was evaluated, to shed light on the challenges these deep-water species are facing in the context of fishing activity and a warming climate.

New insights in oocyte dynamics shed light on the complexities associated with fish reproductive strategies.

Information on temporal variations in stock reproductive potential (SRP) is essential in fisheries management. Despite this relevance, fundamental understanding of egg production variability remains largely unclear due to difficulties in tracking the underlying complex fluctuations in early oocyte recruitment that determines fecundity. We applied advanced oocyte packing density theory to get in-depth, quantitative insights across oocyte stages and seasons, selecting the commercially valuable European hake (Merluccius merluccius) as a case study.

Trade-offs between life-history traits in a coldwater fish in the Mediterranean Sea: the case of blue whiting Micromesistius poutassou.

A combination of traditional and emerging methodologies was used to assess the trade-offs between several life-history traits (linked to reproduction and condition) and parasitism in a commercially-exploited cold-water species, blue whiting Micromesistius poutassou, in the Mediterranean Sea. The use of histological and gravimetric methods revealed conflicting evidence as to the fecundity type (indeterminate or determinate) of this species. Moreover, there seem to be condition-mediated compensations between egg quality and egg quantity.

Management of neonates with right-sided aortic arch and esophageal atresia: International survey on IPEG AND ESPES members´ experience.

Aim: The optimum surgical approach of neonates with right-sided aortic arch (RAA) and esophageal atresia (EA)/tracheoesophageal fistula (TEF) is still an unsolved question. In order to propose an operative algorithm in the era of endoscopic surgery, we performed an international survey to know the current practice between pediatric endoscopic surgeons. Two of the most important societies in endoscopic pediatric surgery were queried: the International Pediatric Endosurgery Group (IPEG) and the European Society of Paediatric Endoscopic Surgeons (ESPES).

Kidney transplantation in children weighing 15 kg or less is challenging but associated with good outcome.

Objective: Pediatric kidney transplantation (KT) in small children is assumed to be related to potential surgical complications that may cause severe morbidity and graft loss. The aim of our study was to analyze the outcome of KT recipients weighing ≤15 kg, focusing on surgical complications, associated morbidity and mortality, as well as allograft loss.

Methods: We reviewed our retrospective institutional database for recipients of KT between January 2000 and December 2014 with body weight ≤15 kg.

Body reserves mediate trade-offs between life-history traits: new insights from small pelagic fish reproduction.

Limited resources in the environment prevent individuals from simultaneously maximizing all life-history traits, resulting in trade-offs. In particular, the cost of reproduction is well known to negatively affect energy investment in growth and maintenance. Here, we investigated these trade-offs during contrasting periods of high versus low fish size and body condition (before/after 2008) in the Gulf of Lions.

Links between parasitism, energy reserves and fecundity of European anchovy, Engraulis encrasicolus, in the northwestern Mediterranean Sea.

The European anchovy, Engraulis encrasicolus L. 1758, is one of the most sought-after target species in the northwestern Mediterranean Sea. However, this stock currently consists of small individuals, and landings are reported to have decreased considerably.

Failed pyeloplasty in children: Is robot-assisted laparoscopic reoperative repair feasible?

Objective: In this study we aim to demonstrate that robot-assisted laparoscopic (RAL) reoperative repair is safe and effective and even less technically demanding than open repair for recurrent ureteropelvic-junction obstruction (UPJO).

Study Design: A retrospective study was conducted of all cases of failed open pyeloplasties who underwent RAL reoperative repair at our institution between January 2010 and December 2013. The general surgical procedure was the same we previously described for robot-assisted laparoscopic pyeloplasty.

Human health benefits supplied by Mediterranean marine biodiversity.

This paper summarizes the overall benefits supplied by Mediterranean marine biodiversity to human health and highlights the anthropogenic and environmental causes that are threatening these benefits. First, the Mediterranean Sea is a valuable source of seafood, which is an important component of the so-called "Mediterranean diet". This type of diet has several health benefits, including cardio and cancer protective effects, which are attributed to the high intake of seafood-derived n-3 (omega-3) fatty acids.

Therapeutic indications of fetoscopy: a 5-year institutional experience.

Background: Prenatal ultrasound study allows the detection of fetal malformations. Intrauterine interventions are now contemplated to correct, or interfere with, the natural history of these anomalies. Minimally invasive techniques, such as the so-called "Fetendo" (fetal endoscopy), are now therapeutic possibilities.
