Omega-3 Fatty Acids in Arterial Hypertension: Is There Any Good News?

Omega-3 polyunsaturated fatty acids (ω-3 PUFAs), including alpha-linolenic acid (ALA) and its derivatives eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are “essential” fatty acids mainly obtained from diet sources comprising plant oils, marine blue fish, and commercially available fish oil supplements. Many epidemiological and retrospective studies suggested that ω-3 PUFA consumption decreases the risk of cardiovascular disease, but results of early intervention trials have not consistently confirmed this effect. In recent years, some large-scale randomized controlled trials have shed new light on the potential role of ω-3 PUFAs, particularly high-dose EPA-only formulations, in cardiovascular prevention, making them an attractive tool for the treatment of “residual” cardiovascular risk. ω-3 PUFAs' beneficial effects on cardiovascular outcomes go far beyond the reduction in triglyceride levels and are thought to be mediated by their broadly documented “pleiotropic” actions, most of which are directed to vascular protection. A considerable number of clinical studies and meta-analyses suggest the beneficial effects of ω-3 PUFAs in the regulation of blood pressure in hypertensive and normotensive subjects. These effects occur mostly through regulation of the vascular tone that could be mediated by both endothelium-dependent and independent mechanisms. In this narrative review, we summarize the results of both experimental and clinical studies that evaluated the effect of ω-3 PUFAs on blood pressure, highlighting the mechanisms of their action on the vascular system and their possible impact on hypertension, hypertension-related vascular damage, and, ultimately, cardiovascular outcomes

Zapteryx brevirostris, Shortnose Guitarfish

The Shortnose Guitarfish (Zapteryx brevirostris) is a small (to 66 cm total length) benthic shark-like ray that occurs in the Southwest Atlantic from Espírito Santo state, Brazil to Buenos Aires, Argentina. It inhabits inshore waters over soft substrates at depths of 2–140 m. It is captured in intense and largely unmanaged artisanal and commercial demersal trawl and gillnet fisheries throughout its geographic range. There are two estimates of population reduction. First, in Santa Catarina state, Brazil, catch-perunit-effort (CPUE) decreased 90% from 100 kg/hr in the 1980s to 10 kg/hr in 2005, the equivalent of a population reduction of >85% over three generation lengths (21 years). Second, in Uruguay, the research trawl survey CPUE declined by nearly 40%; in the 1980s and early 1990s, 2,200 kg/hr were caught, and between 2013 and 2017 there were just over 1,400 kg/hr caught, the equivalent of a population reduction of >25% over three generation lengths (21 years). Furthermore, demographic analyses have shown that this species is being overfished given the level of mortality it is exposed to. This guitarfish is subjected to intense and mostly unmanaged fishing pressure across its limited range, it has no refuge at depth, and where recorded in landings it has declined. Overall, it is suspected that the Shortnose Guitarfish has undergone a population reduction of 50–79% over the past three generation lengths (21 years), and it is assessed as Endangered A2bd.Fil: Pollom, R..

Narcine brasiliensis, Lesser Numbfish

The Lesser Numbfish (Narcine brasiliensis) is a small (to 45 cm total length) ray that occurs in the Southwest Atlantic from southern Brazil to Buenos Aires Province, Argentina. It is benthic on soft substrates of the continental shelf at depths of 6?60 m. It is captured in intense and largely unmanaged commercial and artisanal trawl and beach seine fisheries throughout much of its geographic range. A population reduction is suspected from the peak and subsequent declines in reported ray landings from the Rio del Plata area. This species is discarded when caught and discard survival rates are unknown, but are suspected to be variable based on the injuries of captured individuals. Although this ray is subject to high fishing pressure across its range, it is still observed commonly in fisheries despite this pressure. It is suspected that the Lesser Numbfish has undergone a population reduction of 20-29% over the past three generations (26 years), and it is assessed as Near Threatened (nearly meeting Vulnerable A2d).Fil: Pollom, R..

Sympterygia bonapartii, Smallnose Fanskate

The Smallnose Fanskate (Sympterygia bonapartii) is a medium-sized (to 88 cm total length) skate that occurs in the Southeast Pacific in the Strait of Magellan, Chile, and in the Southwest Atlantic from Rio de Janeiro, Brazil to Santa Cruz, Argentina. It is demersal on the continental shelf and upper slope and inhabits depths down to 100 m and occasionally to 500 m deep. This skate is captured in intense artisanal and commercial demersal trawl and longline fisheries and recreational fisheries in Argentina. Research trawl surveys conducted on the southern Brazilian shelf indicate a reduction in catch-per-unit-effort (CPUE) of 94% between 1980 and 2005. In Uruguay, research surveys exhibit an increase in catch-per-unit-effort between 1984 and 2008 followed by a stabilization. Overall, the Smallnose Fanskate is subjected to intense largely unregulated fishing pressure across most of its range, but is able to survive when discarded. The larger part of this species' range is in central and southern Argentina where fishing mortality is likely to be lower. Due to the level of fisheries mortality that this species is exposed in the northern part of its range, balanced with lower pressure in the south, and its high survivorship when discarded, it is suspected that the Smallnose Fanskate has undergone a population reduction of 20-29% over the past three generations (49.5 years), and it is assessed as Near Threatened (nearly meeting Vulnerable A2bd).Fil: Pollom, R..

Lipoprotein(a): Just an Innocent Bystander in Arterial Hypertension?

Elevated plasma lipoprotein(a) [Lp(a)] is a relatively common and highly heritable trait conferring individuals time-dependent risk of developing atherosclerotic cardiovascular disease (CVD). Following its first description, Lp(a) triggered enormous scientific interest in the late 1980s, subsequently dampened in the mid-1990s by controversial findings of some prospective studies. It was only in the last decade that a large body of evidence has provided strong arguments for a causal and independent association between elevated Lp(a) levels and CVD, causing renewed interest in this lipoprotein as an emerging risk factor with a likely contribution to cardiovascular residual risk. Accordingly, the 2022 consensus statement of the European Atherosclerosis Society has suggested inclusion of Lp(a) measurement in global risk estimation. The development of highly effective Lp(a)-lowering drugs (e.g., antisense oligonucleotides and small interfering RNA, both blocking LPA gene expression) which are still under assessment in phase 3 trials, will provide a unique opportunity to reduce “residual cardiovascular risk” in high-risk populations, including patients with arterial hypertension. The current evidence in support of a specific role of Lp(a) in hypertension is somehow controversial and this narrative review aims to overview the general mechanisms relating Lp(a) to blood pressure regulation and hypertension-related cardiovascular and renal damage

Designing a mHealth clinical decision support system for Parkinson's disease: a theoretically grounded user needs approach.

BACKGROUND: Despite the established evidence and theoretical advances explaining human judgments under uncertainty, developments of mobile health (mHealth) Clinical Decision Support Systems (CDSS) have not explicitly applied the psychology of decision making to the study of user needs. We report on a user needs approach to develop a prototype of a mHealth CDSS for Parkinson's disease (PD), which is theoretically grounded in the psychological literature about expert decision making and judgement under uncertainty. METHODS: A suite of user needs studies was conducted in 4 European countries (Greece, Italy, Slovenia, the UK) prior to the development of PD_Manager, a mHealth-based CDSS designed for Parkinson's disease, using wireless technology. Study 1 undertook Hierarchical Task Analysis (HTA) including elicitation of user needs, cognitive demands and perceived risks/benefits (ethical considerations) associated with the proposed CDSS, through structured interviews of prescribing clinicians (N = 47). Study 2 carried out computational modelling of prescribing clinicians' (N = 12) decision strategies based on social judgment theory. Study 3 was a vignette study of prescribing clinicians' (N = 18) willingness to change treatment based on either self-reported symptoms data, devices-generated symptoms data or combinations of both. RESULTS: Study 1 indicated that system development should move away from the traditional silos of 'motor' and 'non-motor' symptom evaluations and suggest that presenting data on symptoms according to goal-based domains would be the most beneficial approach, the most important being patients' overall Quality of Life (QoL). The computational modelling in Study 2 extrapolated different factor combinations when making judgements about different questions. Study 3 indicated that the clinicians were equally likely to change the care plan based on information about the change in the patient's condition from the patient's self-report and the wearable devices. CONCLUSIONS: Based on our approach, we could formulate the following principles of mHealth design: 1) enabling shared decision making between the clinician, patient and the carer; 2) flexibility that accounts for diagnostic and treatment variation among clinicians; 3) monitoring of information integration from multiple sources. Our approach highlighted the central importance of the patient-clinician relationship in clinical decision making and the relevance of theoretical as opposed to algorithm (technology)-based modelling of human judgment

Sphyrna tudes, Smalleye Hammerhead

The Smalleye Hammerhead (Sphyrna tudes) is a medium-sized (to 150 cm total length) shark that occurs in the Western Central and Southwest Atlantic from Colombia to the Rio de La Plata, Argentina. It inhabits inshore waters over the continental shelf at depths of 5–80 m. It is captured in intense and largely unmanaged commercial and artisanal beach seines, gillnets, longlines, and trawls throughout its geographic range. This shark is targeted or retained as bycatch for its meat, which is consumed or sold locally. There are few data on population reduction but these intensive unmanaged fisheries are suspected to have caused reductions and possibly local extinctions throughout this species' range. For example, in Brazil, this hammerhead has not been recorded in 35 years from Ceará state and it is considered by local fishers to be depleted in Bahia state. This shark is supposed to be strictly protected in Brazil, but it is clear that it is still landed and traded in various states. Overall, due to intense and largely unmanaged fisheries across its range, lack of refuge at depth, suspected declines in many areas and local extinctions suspected from an absence of records (despite continued sampling and observation), and its relatively unproductive life history, it is suspected that the Smalleye Hammerhead has undergone a population reduction of >80% over the past three generations (37 years), and it is assessed as Critically Endangered A2bd.Fil: Pollom, R..
