RESUMEN
Gastric ulcers are a type of digestive disease that can severely affect a person's quality of life. Our study aimed to investigate the effects of fish oil on ethanol-induced gastric ulcers in rats, with the purpose of providing more comprehensive information on the topic. The study looked at various factors such as gastric ulcer index, and nitric oxide (NO) levels in stomach tissue. To investigate apoptosis, the mRNA levels of Bax, Bcl-2, and Caspase 3 were analyzed. The results showed that fish oil can reduce gastric acidity and the gastric ulcer index in cases of ethanol-induced gastric ulcers. It was found that fish oil can increase NO levels and improve the anti-apoptotic system by increasing the expression of Bcl-2 while decreasing the expression of Bax and Caspase 3. In general, the study demonstrates that fish oil can protect the stomach from ethanol-induced damage by reducing the apoptosis pathway via nitric oxide.

BACKGROUND AND AIMS: Cardiometabolic multimorbidity (CMM) has risen as a global issue of public health, with an in-creasing prevalence and more severe clinical prognosis. This study aimed to estimate the association between use of fish oil and mortality among patients with CMM. METHODS AND RESULTS: In this prospective study based on UK Biobank, participants with ≥2 of cardiometabolic diseases (CMDs, including coronary heart disease [CHD], diabetes, hypertension, and stroke in this study) at recruitment were included. Use of fish oil was derived from touchscreen questionnaires at baseline. All-cause and cardiovascular mortality were accessed via electronic health-related records. Kaplan-Meier curves and flexible parametric Royston-Parmar proportion-hazard models were fitted to assess the as-sociations of fish-oil use with all-cause, cardiovascular mortality, and related life expectancy alterations. Among 30 068 participants from UK Biobank (67.9% men; mean age 61.75 years), 5357 deaths were reported during 12.03 years of follow-up. For patients with CMM, use of fish oil was associated with a 17% lower risk of all-cause mortality (95% confidence interval [95% CI] 0.78-0.88, P < 0.001), and 19% lower risk of cardiovascular mortality (95% CI 0.72-0.90, P < 0.001) in multivariable-adjusted models. At 45 years old, using fish oil was associated with 1.66 years of life expectancy gained. CONCLUSION: Among patients with CMM, use of fish oil was associated with a significantly reduced risk of all-cause, cardiovascular mortality, and prolonged life expectancy.

This study investigated the effect of perilla oil (PO) on an ulcerative colitis mouse model. Five-week-old male C57BL/6J mice were divided into HD (high-fat diet control), HDD (high-fat diet along with dextran sodium sulfate [DSS] administration), HDD + FO, HDD + PO, and HDD + OO where HDD + FO, HDD + PO, and HDD + OO groups were treated with fish oil (FO), PO, and olive oil (OO), respectively. Biochemical analysis of serum, quantitative polymerase chain reaction, and western blotting of colon tissue were conducted to measure inflammatory marker levels. Administration of DSS resulted in colon shortening and a higher disease activity score than HD group. These symptoms were significantly reversed in the oil-treated groups. The body weight loss after DSS administration was significantly lower in the HDD + PO and HDD + OO groups than in the HDD and HDD + FO groups. PO significantly attenuated the levels of tumor necrosis factor-α, interleukin (IL)-6, and IL-1ß in the serum and colon. The mRNA expression levels of proinflammatory markers in the colon were reduced, whereas those of tight junction proteins and epithelial defense barrier-associated markers were increased by PO treatment. The protein expression of p-p65 was significantly lower in the PO-treated group than the HDD group. In summary, this study revealed that PO improved colitis in the DSS-induced mouse model, indicating its potential role in managing conditions such as ulcerative colitis.

AIMS: Mixed effects of fish oil supplementation on the risks of atrial fibrillation (AF) were observed in several large-scale randomized controlled trials. Whether this relationship would be modified by genetic AF risk, baseline cardiovascular disease (CVD) status and background oily fish consumption are unknown. METHODS AND RESULTS: We included 468 665 participants without AF at baseline from the UK Biobank cohort. The association between fish oil supplementation and the AF risk was assessed in the study cohort and in several subgroups, including genetic AF predisposition, baseline CVD status, and background oily fish consumption. During a median follow-up of 11.1 years, fish oil users had a higher rate of incident AF (6.2% vs. 5.2%, adjusted hazard ratio of 1.10, and 95% confidence interval of 1.07, 1.13). Compared with non-users, fish oil users had a higher rate of incident AF in the low (3.7% vs. 3.0%, P= 0.02), intermediate (5.8% vs. 4.8%, P < 0.0001), and high (9.8% vs. 8.1%, P < 0.0001) genetic AF risk groups. In participants without CVD at baseline, fish oil users had a higher rate of incident AF (5.3% vs. 4.1%, P < 0.0001), which was not observed in participants with CVD at baseline (11.6% vs. 11.1%, P = 0.56), with significant interaction (P-interaction < 0.0001). The association between fish oil supplementation and the AF risk was not modified by background oily fish consumption (P-interaction = 0.62). CONCLUSION: Habitual fish oil supplementation was associated with the risk of incident AF, regardless of genetic AF predisposition and background oily fish consumption. This association was observed only in individuals without CVD at baseline.

BACKGROUND AND AIMS: Elevated circulating levels of CathepsinD (CatD) have been linked to metabolic deviations including liver inflammation. We investigated 1) whether supplementation with probiotics and/or fish oil affects CatD and 2) whether the CatD concentration would associate with gestational diabetes (GDM), low-grade inflammation, lipid metabolism, body fat % and dietary composition. METHODS AND RESULTS: Overweight/obese pregnant women (n = 438) were randomized into fish oil + placebo, probiotics + placebo, fish oil + probiotics or placebo + placebo groups. Fish oil contained 1.9 g docosahexaenoic acid and 0.22 g eicosapentaenoic acid and probiotics were Lacticaseibacillusrhamnosus HN001 (formerly Lactobacillusrhamnosus HN001) and Bifidobacteriumanimalis ssp. lactis 420, 1010 colony-forming units each). Serum CatD levels were analysed by ELISA, GlycA and lipid metabolites by NMR, high sensitive C-reactive protein (hsCRP) by immunoassay, and intakes of energy yielding nutrients and n-3 and n-6 fatty acids from food diaries at both early and late pregnancy. GDM was diagnosed by OGTT. CatD concentrations did not differ between the intervention groups or by GDM status. Multivariable linear models revealed that body fat % and GlycA affected CatD differently in healthy women and those with GDM. CONCLUSION: The serum CatD concentration of pregnant women was not modified by this dietary intervention. Serum CatD was influenced by two parameters, body fat and low grade inflammation, which were dependent on the woman's GDM status. CLINICAL TRIAL REG.

WHAT IS KNOWN AND OBJECTIVES: Errors involving the delivery of IVFE containing soybean oil have known significant complications, including fat overload syndrome. However, little is known regarding the risks of fat overload syndrome with other types of lipid emulsions. CASE SUMMARY: We describe a medication administration error that resulted in rapid fish oil-base lipid emulsion (Omegaven) infusion in a five-month-old infant with parenteral nutrition associated liver disease (PNALD). The medication administration error resulted in bolus infusion of Omegaven over 12 min (5 g/kg/h) instead of 12 h (0.083 g/kg/h). WHAT IS NEW AND CONCLUSION: No adverse reactions were notes because of the rapid infusion, supporting conclusion that rapid infusion of fish oil will not result in fat overload syndrome.

OBJECTIVE: To compare extrahepatic adverse events during fish oil lipid emulsion (FOLE) or soybean oil lipid emulsion (SOLE) treatment in children with intestinal failure-associated liver disease (IFALD). STUDY DESIGN: In this multicenter integrated analysis, bleeding, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), infections, and signs of lipid emulsion intolerance were compared between FOLE recipients (1 g/kg/d) (n = 189) and historical controls who received SOLE (≤3 g/kg/d) (n = 73). RESULTS: When compared with SOLE recipients, FOLE recipients had a lower gestational age (30.5 vs 33.0 weeks; P = .0350) and higher baseline direct bilirubin (DB) (5.8 vs 3.0 mg/dL; P < .0001). FOLE recipients had a decreased incidence of bleeding (P < .0001), BPD (P < .001), ROP (P < .0156), bacterial and fungal infections (P < .0001), and lipid intolerance signs (P < .02 for all). Patients with bleeding vs patients without bleeding had higher baseline DB; the ORs for baseline DB (by mg/dL) and treatment (FOLE vs SOLE) were 1.20 (95% CI: 1.10, 1.31; P ≤ .0001) and 0.22 (95% CI: 0.11, 0.46; P ≤ .0001), respectively. In preterm infants, a higher BPD (P < .0001) and ROP incidence (P = .0071) was observed in SOLE recipients vs FOLE recipients. CONCLUSIONS: Children with IFALD who received FOLE had fewer extrahepatic adverse events, including a decreased incidence of bleeding, preterm comorbidities, and lipid intolerance signs compared with children with IFALD who received SOLE.

BACKGROUND: Erenumab, a monoclonal antibody against the calcitonin gene-related peptide (CGRP) receptor, is registered for migraine prevention. Compared to other conventional migraine prevention medicines (i.e. topiramate, betablockers and amitriptyline) erenumab has better tolerability. Impaired hemostasis has not been reported previously. Here, we report the first case of an increased tendency to bruise in a migraine patient treated with erenumab. CASE PRESENTATION: A 41-year old female migraine patient was treated with erenumab for 12 months, which led to a significant reduction of headache and migraine days. Three months after treatment start, she experienced increased tendency to bruise leading to extreme ecchymosis after 4 months treatment. Platelet counts and aggregation, thromboelastography, activated partial thromboplastin time (APTT) and international normalized ratio (INR) were all normal. Thorough interview revealed intake of fish oil supplements for many years prior to treatment. The increased tendency to bruise subsided after discontinuation of fish oil supplements. CONCLUSION: The combination of fish oil supplements and erenumab may cause increased tendency to bruise. Erenumab has no effect on the platelets per se but may cause impaired wound healing by suppression of CGRP. Thus, small and unnoticeable bruises may be aggravated instead in patients with tendency to bruise caused by for instance fish oil supplements.

AIMS: The increase of arterial stiffness is an independent risk factor for cardiovascular diseases (CVD). Fish oil supplementation was shown to reduce the risk of CVD outcomes. However, the effects of fish oil on arterial stiffness remains controversial. This meta-analysis summarized existing randomized clinical trials (RCTs) to determine whether fish oil can affect arterial stiffness in adults. DATA SYNTHESIS: Systematic searches were performed using the PubMed/Medline, EMbase, Cochrane database, Clinical trials, and Web of Science. All RCTs assessed the effect of fish oil intervention on carotid to femoral-Pulse Wave Velocity (cf-PWV), brachial to ankle-PWV (ba-PWV), augmentation index (AIx) and AIx75 were considered. A fixed-effect model was used to calculate the pooled effect. A total of 14 RCTs were included. The pooled data analysis showed that fish oil significantly reduced PWV levels (SMD: -0.145, 95%CI: -0.265 to -0.033, P = 0.012) compared to the control group. In subgroup analyses, a significant decrease in PWV was found in trials that fish oil with low dosages (≤1.8 g/d), short time (<24 weeks), low DHA to EPA ratio (DHA/EPA<1) and among young participant (<50 years old). Besides, the effect of fish oil was more obvious in ba-PWV compared to cf-PWV. In contrast, the effect of fish oil supplementation on AIx (WMD: -0.588%, 95% CI: -2.745 to 1.568, P = 0.593) and AIx75 (WMD: 0.542%, 95% CI: -1.490 to 2.574, P = 0.601) was nonsignificant. CONCLUSIONS: The current study showed that fish oil supplementation had a beneficial effect on pulse wave velocity.

INTRODUCTION: Vitamin D intoxication (VDI) is a well-known cause of hypercalcemia in children and leads to serious kidney, heart, and neurological problems. In the treatment of VDI, the goal is to correct hypercalcemia. Our aim was to evaluate the clinical features of patients with VDI, identify the causes of VDI in our region, and help guide precautions and treatment of VDI. MATERIALS AND METHODS: The medical records of patients with VDI presenting between January 2015 and December 2019 were retrospectively analyzed. RESULTS: In total, 38 patients aged 0.3-4 years including 20 males (52.6%) were included in the study. Vomiting (65.8%), loss of appetite (47.4%), and constipation (31.6%) were the most common symptoms. The cause of intoxication was prescribed D3 vials in 23 patients, non-prescribed D3 vials in nine patients, and incorrectly produced fish oil supplement in six patients. Admission serum calcium and 25 (OH) D levels were 3.75±0.5mmol/L and 396±110ng/mL, respectively. A statistically significant correlation was found between the serum calcium levels at the time of diagnosis and the dose of vitamin D received, serum 25 (OH) D, phosphorus, and parathyroid (PTH) levels. Nephrocalcinosis was present in 15 (39.5%) patients. The mean time to achieve normocalcemia was 6.18±2 days. The mean time to achieve normocalcemia in patients treated with pamidronate was 5.94±0.7 days. CONCLUSION: Stoss therapy should not be administered for children of families with problems of adherence to treatment. It should be noted that VDI may develop as a result of improperly produced nutritional supplements. General practitioners and pediatricians must be aware of VDI risks and explain them to parents. Pamidronate is effective for treating VDI in children.

BACKGROUND: Parenteral nutrition (PN) is critical for the growth and development of premature neonates who are unable to reach nutrition goals enterally. Using soybean-oil emulsions in PN is a risk factor for cholestasis, leading to alternative dosing strategies including a reduction in total lipid prescribed. Recently, SMOFlipid has been utilized with the goal of avoiding cholestasis while maintaining energy intake. The aim of our study was to compare the incidence of PN-associated cholestasis (PNAC) in patients admitted to the neonatal intensive care unit (NICU) who received either Intralipid 20% or SMOFlipid. METHODS: This single-center, retrospective study evaluated all NICU patients who received PN for ≥14 days. Patients who received SMOFlipid were compared with those who received Intralipid. The primary end point was incidence of PNAC. Secondary end points included (1) prevalence of elevated liver function tests; (2) effect on select laboratory parameters; (3) development of PNAC by age; and (4) incidence of retinopathy of prematurity. RESULTS: A total of 136 neonates were included. Nine of 55 patients (16.4%) in the Intralipid group and 2 of 81 patients (2.5%) in the SMOFlipid group developed cholestasis, defined as direct bilirubin > 2 mg/dL or direct bilirubin > 20% of total bilirubin, when total bilirubin is >5 mg/dL, on or before 30 days post initiation of PN (P = .007). CONCLUSION: Use of SMOFlipid as the lipid emulsion component of PN may be beneficial in prevention of PNAC in NICU patients that are receiving PN for ≥2 weeks.

INTRODUCTION: Introduction: a lipid emulsion (LE) may result in different immunomodulatory effects depending on its fatty acid composition. LEs enriched with fish oil and those based on olive oil (OOBE) have shown advantages over those derived from soybean oil, although very few studies have compared these with each other, and none was performed in critically ill surgical patients. Objectives: to demonstrate non-inferiority for the therapeutic efficacy of SMOFlipid® (enriched with fish oil) versus Clinoleic® (OOBE) in relation to the occurrence of nosocomial infection and other evolutionary parameters. To demonstrate non-inferiority in the safety profile of SMOFlipid® versus Clinoleic® in terms of mortality and adverse events. Material and method: a phase-III, non-inferiority clinical trial performed in critically ill postsurgical patients. The subjects were randomized to receive SMOFlipid® or Clinoleic®. For comparison of qualitative variables case frequencies and percentages were obtained using the Chi-squared test or Fisher's exact test. Means were compared between groups using Student's t-test. A p-value lower than 0.05 was considered statistically significant. The Farrington-Manning, Miettinen-Nurminen, and Gart-Nam tests were applied in the main non-inferiority analysis of the primary endpoint. Results: during de inclusion period 73 patients were selected, 37 of whom received Clinoleic® and 36 SMOFlipid®. Regarding the variable "decrease in nosocomial infections", SMOFlipid® proved to be non-inferior to Clinoleic®. Regarding the main variable "mortality", SMOFlipid® proved to be non-inferior to Clinoleic®. There were no statistically significant differences in the occurrence of adverse effects either. Conclusions: in our study, SMOFlipid® proved to be non-inferior to Clinoleic® in terms of efficacy and safety.
INTRODUCCIÓN: Introducción: las emulsiones lipídicas (EL) pueden asociar distintos efectos inmunomoduladores dependiendo de su composición de ácidos grasos. Las EL enriquecidas con aceite de pescado y las basadas en aceite de oliva (EBAO) han mostrado ventajas frente a las derivados del aceite de soja, aunque son muy escasos los estudios que las comparan entre sí y no existe ninguno en pacientes críticos quirúrgicos. Objetivos: Demostrar la no inferioridad de la eficacia terapéutica de SMOFlipid® (enriquecida con aceite de pescado) frente a Clinoleic® (EBAO) en relación con la aparición de infecciones nosocomiales y otros parámetros evolutivos. Demostrar la no inferioridad de la seguridad de SMOFlipid® frente a Clinoleic® expresada como aparición de mortalidad y acontecimientos adversos. Material y método: ensayo clínico de fase III, de no inferioridad, realizado en pacientes críticos posquirúrgicos. Los sujetos se aleatorizaron para recibir SMOFlipid® o Clinoleic®. Para comparar variables cualitativas se obtuvieron la frecuencia y el porcentaje de casos, realizando la prueba del chi cuadrado o el test de Fisher. Las medias entre dos grupos se compararon empleando el test de la "t" de Student. Se consideró estadísticamente significativo un valor de p menor de 0,05. Para el análisis principal de no inferioridad de la variable principal se aplicaron los test de Farrington-Manning, Miettinen-Nurminen y Gart-Nam. Resultados: se incluyeron 73 pacientes, de los cuales 37 recibieron Clinoleic® y 36 SMOFlipid®. En la variable "disminución de infecciones nosocomiales", SMOFlipid® demostró no ser inferior a Clinoleic®. En la variable principal "mortalidad", SMOFlipid® demostró no ser inferior a Clinoleic®. Tampoco existieron diferencias estadísticamente significativas en cuanto a la aparición de efectos adversos. Conclusiones: en nuestro estudio, SMOFlipid® demostró no ser inferior a Clinoleic® en términos de eficacia y seguridad.

BACKGROUND: Lipaemic interference on automated analysers has been widely studied using soy-based emulsion such as Intralipid. Due to the greater adoption of fish oil-based lipid emulsion for total parenteral nutrition in view of improved clinical outcomes, we seek to characterize the optical properties of SMOFlipid 20% (Fresenius Kabi, Bad Homburg, Germany), a fish oil-based emulsion, on the Roche Cobas 6000 chemistry analyser (Roche Diagnostic, Basel, Switzerland). METHOD: Various amounts of SMOFlipid were spiked into pooled serums. We plotted Roche Cobas Serum Index Gen.2 Lipaemia Index (L-index) against the amount of SMOFlipid added. We then studied the interference thresholds for aspartate aminotransferase, alanine aminotransferase, albumin and renal panel analytes using SMOFlipid. We subjected five levels of spiked lipaemia to high-speed centrifugation and analysed the specimens pre- and post-centrifugation. To postulate whether fish oil-based lipid emulsion interferes with laboratory results in the clinical setting, we calculated concentrations of SMOFlipid post-lipid rescue therapy and steady-state concentration of a typical total parenteral nutrition regime using pharmacokinetic principles. RESULTS: SMOFlipid optical behaviour is similar to Intralipid using the Serum Index Gen.2 L-index, with 1 mg/dL of SMOFlipid representing 1 unit of L-index. Manufacturer-stated interference thresholds are accurate for alanine aminotransferase, aspartate aminotransferase, albumin, urea and creatinine. High-speed centrifugation at 60 min 21,100g facilitates the removal of fish oil-based SMOFlipid. CONCLUSION: Based on the interference thresholds we verified and pharmacokinetics parameters provided by SMOFlipid manufacturer, total parenteral nutrition may not interfere with chemistry analytes given sufficient clearance, but lipid rescue therapy will interfere. Further studies assessing lipaemic interference on immunoassays are needed.

Eicosapentaenoic acid (EPA), an omega-3 fatty acid, has been widely used to prevent cardiovascular disease (CVD) and treat brain diseases alone or in combination with docosahexaenoic acid (DHA). However, the impact of EPA and DHA supplementation on normal cognitive function and the molecular targets of EPA and DHA are still unknown. We show that acute administration of EPA impairs learning and memory and hippocampal LTP in adult and prepubescent mice. Similar deficits are duplicated by endogenously elevating EPA in the hippocampus in the transgenic fat-1 mouse. Furthermore, the damaging effects of EPA are mediated through enhancing GABAergic transmission via the 5-HT6R. Interestingly, DHA can prevent EPA-induced impairments at a ratio of EPA to DHA similar to that in marine fish oil via the 5-HT2CR. We conclude that EPA exhibits an unexpected detrimental impact on cognitive functions, suggesting that caution must be exercised in omega-3 fatty acid supplementation and the combination of EPA and DHA at a natural ratio is critical for learning and memory and synaptic plasticity.

PURPOSE OF REVIEW: Increasing interest has focused on the potential cardioprotective effects of the omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on the basis of findings from epidemiology and cohort studies. This review will summarize the findings of contemporary clinical trials of omega-3 fatty acids. RECENT FINDINGS: Although a large clinical trial performed prior to the widespread use of statins demonstrated cardiovascular benefit with fish oils, subsequent studies have failed to reproduce this result. More recent studies have demonstrated a reduction in cardiovascular risk with administration of high-dose EPA, but not a carboxylic acid formulation containing both EPA and DHA or with lower doses of omega-3 fatty acids. SUMMARY: Administration of omega-3 fatty acids differing in either composition or dose produce variable effects on cardiovascular outcomes. This has implications for both the public health and pharmacological approach to cardiovascular prevention.

The role of n-3 polyunsaturated fatty acids (PUFAs) in alcoholic liver disease (ALD) has been controversial. N-3 PUFA oxidation in animal feeding stuffs was rarely concerned, likely contributing to inconsistent outcomes. Here, we report the impacts of oxidized fish oil (OFO) on ALD in C57BL/6 mice. Alcohol exposure increased plasma aminotransferase levels and hepatic inflammation. These deleterious effects were ameliorated by unoxidized FO but exacerbated by OFO. Sequencing analysis showed the accentuated intestinal dysbiosis and the increased proportion of Proteobacteria in OFO-fed mice. Intestinal sterilization by antibiotics completely abolished OFO-aggravated liver injury. Additionally, alcohol exposure leads to the greater increase in plasma endotoxin and decrease in intestinal tight junction protein expressions in OFO-fed mice. Stabilization of intestinal barrier by obeticholic acid markedly blunted OFO-aggravated liver injury in alcohol-fed mice. These results demonstrate that OFO exacerbates alcoholic liver injury through enhancing intestinal dysbiosis, barrier dysfunction, and hepatic inflammation mediated by gut-derived endotoxin.
