Nutrition in clinical practice : official publication of the American Society for Parenteral and Enteral Nutrition. 2022;(4):762-772
Abstract
Bolus and continuous nutrition are commonly used enteral nutrition (EN) administration methodologies. Currently, there is insufficient evidence to establish which is the most effective method for reducing gastrointestinal complications in adult patients. The aim of this review is to evaluate the impact of bolus/intermittent EN compared with continuous EN for the following outcomes: diarrhea, constipation, emesis/vomiting, gastric residual volume, aspiration, and glycemic control in adult patients receiving intragastric prepyloric EN in the hospital setting. Bibliographical research was performed on the following databases: PubMed, Embase, CINAHL, and the Cochrane Central Register of Controlled Trials. The review included all randomized and nonrandomized controlled trials of patients aged ≥18 years with preserved gastrointestinal function. Meta-analysis was performed by Review Manager V.5.3. Seven studies including 551 patients were included in the meta-analysis. Five of these studies reported that the diarrhea rate was higher in the bolus feeding group (risk ratio [RR] = 2.50; 95% CI, 1.17-5.34; P = 0.02), and another five of these studies indicated that the aspiration rate was higher in the continuous feeding group (RR = 0.55; 95% CI, 0.35-0.87; P = 0.01). There were no significant differences for the other outcomes. In conclusion, intermittent EN appears to reduce the incidence of aspiration in the hospital setting; however, it may increase the risk of diarrhea. For future research, we hypothesize the joint use of continuous nutrition until the patient reaches tolerance and then passing to bolus nutrition, thus reducing the incidence of aspiration and enabling a physiological nutrition intake.

Abstract
The mortality rate of hospitalized COVID-19 patients differed strongly between the first three pandemic waves. Nevertheless, their long-term survival has been poorly assessed. The aim of this study was to compare the clinical characteristics and mortality rates of 825 patients with coronavirus disease 2019 (COVID-19) infection who were hospitalized at the Alessandria hub hospital, in Northern Italy, during the first fifty days of the first three pandemic waves. Each subject was followed in terms of vital status for six months from the date of hospital admission or until deceased. Patients admitted during the three waves differed in age (p = 0.03), disease severity (p < 0.0001), Charlson comorbidity index (p = 0.0002), oxygen therapy (p = 0.002), and invasive mechanical ventilation (p < 0.0001). By the end of follow-up, 309 deaths (38.7%) were observed, of which 186 occurred during hub hospitalization (22.5%). Deaths were distributed differently among the waves (p < 0.0001), resulting in being higher amongst those subjects admitted during the first wave. The COVID-19 infection was reported as the main cause of death and patients with a higher mortality risk were those aged ≥65 years [adjusted HR = 3.40 (95% CI 2.20-5.24)], with a higher disease severity [adjusted HR = 1.87 (95%CI 1.43-2.45)], and those requiring oxygen therapy [adjusted HR = 2.30 (95%CI 1.61-3.30)]. In conclusion, COVID-19 patients admitted to our hub hospital during the second and the third waves had a lower risk of long-term mortality than those admitted during the first. Older age, more severe disease, and the need for oxygen therapy were among the strongest risk factors for poor prognosis.

Nutrients. 2021;(2)
Abstract
BACKGROUND Oxysterol relationship with cardiovascular (CV) risk factors is poorly explored, especially in moderately hypercholesterolaemic subjects. Moreover, the impact of nutraceuticals controlling hypercholesterolaemia on plasma levels of 24-, 25- and 27-hydroxycholesterol (24-OHC, 25-OHC, 27-OHC) is unknown. METHODS Subjects (n = 33; 18-70 years) with moderate hypercholesterolaemia (low-density lipoprotein cholesterol (LDL-C:): 130-200 mg/dL), in primary CV prevention as well as low CV risk were studied cross-sectionally. Moreover, they were evaluated after treatment with a nutraceutical combination (Bifidobacterium longum BB536, red yeast rice extract (10 mg/dose monacolin K)), following a double-blind, randomized, placebo-controlled design. We evaluated 24-OHC, 25-OHC and 27-OHC levels by gas chromatography/mass spectrometry analysis. RESULTS 24-OHC and 25-OHC were significantly correlated, 24-OHC was correlated with apoB. 27-OHC and 27-OHC/total cholesterol (TC) were higher in men (median 209 ng/mL and 77 ng/mg, respectively) vs. women (median 168 ng/mL and 56 ng/mg, respectively); 27-OHC/TC was significantly correlated with abdominal circumference, visceral fat and, negatively, with high-density lipoprotein cholesterol (HDL-C). Triglycerides were significantly correlated with 24-OHC, 25-OHC and 27-OHC and with 24-OHC/TC and 25-OHC/TC. After intervention, 27-OHC levels were significantly reduced by 10.4% in the nutraceutical group Levels of 24-OHC, 24-OHC/TC, 25-OHC, 25-OHC/TC and 27-OHC/TC were unchanged. CONCLUSIONS In this study, conducted in moderate hypercholesterolemic subjects, we observed novel relationships between 24-OHC, 25-OHC and 27-OHC and CV risk biomarkers. In addition, no adverse changes of OHC levels upon nutraceutical treatment were found.

Omega-3 Fatty Acids and Neurodegenerative Diseases: New Evidence in Clinical Trials.
Avallone, R, Vitale, G, Bertolotti, M
International journal of molecular sciences. 2019;(17)
Abstract
A nutritional approach could be a promising strategy to prevent or slow the progression of neurodegenerative diseases such as Parkinson's and Alzheimer's disease, since there is no effective therapy for these diseases so far. The beneficial effects of omega-3 fatty acids are now well established by a plethora of studies through their involvement in multiple biochemical functions, including synthesis of anti-inflammatory mediators, cell membrane fluidity, intracellular signaling, and gene expression. This systematic review will consider epidemiological studies and clinical trials that assessed the impact of supplementation or dietary intake of omega-3 polyunsaturated fatty acids on neurodegenerative diseases such as Parkinson's and Alzheimer's diseases. Indeed, treatment with omega-3 fatty acids, being safe and well tolerated, represents a valuable and biologically plausible tool in the management of neurodegenerative diseases in their early stages.

Informational and emotional daily messages to reduce red and processed meat consumption.
Carfora, V, Bertolotti, M, Catellani, P
Appetite. 2019;:104331
Abstract
In the present study we tested a daily messaging intervention aimed at promoting the reduction of red and processed meat consumption (RPMC). We randomly allocated 180 young adults to three different message conditions. Participants in the informational condition read messages on the consequences of excessive RPMC on one's health and the environment. Participants in the emotional condition read messages eliciting anticipated regret for the consequences of excessive RPMC on one's health and the environment. Participants in the control condition read messages on the health and the environment consequences of sugar consumption. We sent messages through a chatbot every morning for two weeks. RPMC, attitude, intention, and anticipated regret regarding RPMC were measured three times: before the two-week messaging intervention (baseline), immediately after the intervention (post intervention) and two months thereafter (follow up). RPMC was also measured through food diaries, completed for two weeks after the intervention. Compared to the control condition, participants exposed to emotional messages reduced RPMC at follow up, while this was not the case for participants exposed to informational messages. In addition, anticipated regret and intention mediated the effects of emotional messages on RPMC. Implications for devising effective messaging interventions to change RPMC are discussed.

Management of high cholesterol levels in older people.
Bertolotti, M, Lancellotti, G, Mussi, C
Geriatrics & gerontology international. 2019;(5):375-383
Abstract
The management of hypercholesterolemia in older adults still represents a challenge in clinical medicine. The pathophysiological alterations of cholesterol metabolism associated with aging are still incompletely understood, even if epidemiological evidence suggests that serum cholesterol levels increase with ongoing age, possibly with a plateau after the age of 80 years. Age is also one of the main determinants of cardiovascular disease, according to all cardiovascular risk estimate tools. Cholesterol-lowering treatment, therefore, would be expected to bring significant protection, even in these patients. Unfortunately, direct experimental evidence is extremely limited, particularly in the very old age strata of the population; a clinical benefit still seems to be present, but the risk for drug-related adverse events is clearly higher. At any rate, at the present time, definite guidelines for the correct management of hypercholesterolemia in older patients are not available. Therefore, the decision whether or not a pharmacological treatment should be set up, and the choice of the drug, need to be tailored to the individual patient, and requires accurate clinical judgment. The specific aspects of frailty and disability, along with the actual age of the patients, have to be considered together, with a comprehensive assessment approach. The present review summarizes the evidence regarding the modifications of cholesterol metabolism in older patients, the impact of lipid-lowering drugs on cardiovascular outcomes and focuses on the considerations that can help to define the most appropriate treatment strategy, in view of the individual functional profile.

Plain language summary
Probiotics have been shown to reduce total cholesterol (TC) and low-density lipoprotein (LDL-C – often called ‘bad’ cholesterol) in people with moderately raised cholesterol levels. A specific strain of probiotic called Bifidobacterium longum BB536, may decrease TC and LDL-C by reducing the reabsorption of cholesterol from the intestine, and, combined with other natural supplements, may be useful to manage high cholesterol in people at low risk of heart disease. This study was conducted to evaluate the effect of a nutraceutical (Lactoflorene Colesterolo®), containing Bifidobacterium longum BB536 (1bn CFUs) combined with red yeast rice (RYR) extract (10 mg/day monacolin K), niacin (16mg) and coenzyme Q10 (20mg) on levels of cholesterol and fats in the blood. This was a 12-week randomised, parallel, double-blind, placebo-controlled study, in which 33 adults at low risk of heart disease were given either the Bifidobacterium combination, or a placebo. Treatment with the Bifidobacterium combination significantly reduced total cholesterol by 16.7%, LDL-C by 25.7%, non-HDL-C by 24% and apolipoprotein-B by 17%. Triglycerides, HDL-C, apolipoprotein AI, lipoprotein (a) and proprotein convertase subtilisin/kexin type 9 (PCSK9) were unchanged. Markers of cholesterol synthesis and absorption suggested that a reduction in the synthesis of cholesterol had occurred without increased absorption of cholesterol. No adverse effects were reported in the study and the compliance rate was high at 97%. The use of nutraceuticals in the prevention of cardiovascular disease, as well as in other areas related to chronic diseases like cancer, is currently expanding.
Abstract
BACKGROUND Probiotics incorporated into dairy products have been shown to reduce total (TC) and LDL cholesterolemia (LDL-C) in subjects with moderate hypercholesterolemia. More specifically, probiotics with high biliary salt hydrolase activity, e.g. Bifidobacterium longum BB536, may decrease TC and LDL-C by lowering intestinal cholesterol reabsorption and, combined with other nutraceuticals, may be useful to manage hypercholesterolemia in subjects with low cardiovascular (CV) risk. This study was conducted to evaluate the efficacy and safety of a nutraceutical combination containing Bifidobacterium longum BB536, red yeast rice (RYR) extract (10 mg/day monacolin K), niacin, coenzyme Q10 (Lactoflorene Colesterolo®). The end-points were changes of lipid CV risk markers (LDL-C, TC, non-HDL-cholesterol (HDL-C), triglycerides (TG), apolipoprotein B (ApoB), HDL-C, apolipoprotein AI (ApoAI), lipoprotein(a) (Lp(a), proprotein convertase subtilisin/kexin type 9 (PCSK9)), and of markers of cholesterol synthesis/absorption. METHODS A 12-week randomized, parallel, double-blind, placebo-controlled study. Thirty-three subjects (18-70 years) in primary CV prevention and low CV risk (SCORE 0-1% in 24 and 2-4% in 9 subjects; LDL-C: 130-200 mg/dL) were randomly allocated to either nutraceutical (N = 16) or placebo (N = 17). RESULTS Twelve-week treatment with the nutraceutical combination, compared to placebo, significantly reduced TC (- 16.7%), LDL-C (- 25.7%), non-HDL-C (- 24%) (all p < 0.0001), apoB (- 17%, p = 0.003). TG, HDL-C, apoAI, Lp(a), PCSK9 were unchanged. Lathosterol:TC ratio was significantly reduced by the nutraceutical combination, while campesterol:TC ratio and sitosterol:TC ratio did not change, suggesting reduction of synthesis without increased absorption of cholesterol. No adverse effects and a 97% compliance were observed. CONCLUSIONS A 12-week treatment with a nutraceutical combination containing the probiotic Bifidobacterium longum BB536 and RYR extract significantly improved the atherogenic lipid profile and was well tolerated by low CV risk subjects.

Abstract
BACKGROUND The aim of this study was to investigate the effects of vitamin D (VD) on the interaction among functional, echocardiographic and hormonal parameters in patients with heart failure (HF) and VD deficiency. METHODS In a randomized, double blind trial, 35 patients with HF and VD<20 ng/mL, received either 300,000 U of oral cholecalciferol followed by 50,000 U/month for 6 months, or placebo treatment. RESULTS Changes in the 6 Minute Walking Test (6MWT) assessed at 3 and 6 months in treatment group was the primary end point. Secondary endpoints were echocardiographic and hormonal changes. The same targets were compared in treated and placebo groups as secondary endpoints. In the treatment group the 6MWT improved at 3 (from 210±104 mt to 225±94 mt; P=0.033) but not at 6 months (from 210±104 mt to 217±94 mt; P=0.288) while PTH dropped at 3 (from 76.8±50.5 to 50.2±20.3 pg/mL; P=0.025), but not at 6 months. 6MWT improvement was negatively related to baseline VD levels. Variation in 6MWT did not significantly differ among groups at 3 (13.6±23.3 vs. 3.6±17.3; P 0.175) and 6 months (12.1±31.4 vs. 0.2±23.2; P 0.225). Left atrial size increased in the placebo group (from 50.8±20.7 to 61.7±36.0 mL/m2; P=0.010). Other hormonal parameters remained unchanged. CONCLUSIONS In summary, the treatment of VD deficiency in patients with HF improved 6MWT after 3 months along with a decrease in PTH levels. However when compared with the placebo arm, treatment of VD deficiency did not influence the final outcomes.

Abstract
BACKGROUND The aim was to evaluate the analgesic efficacy and safety of the dexketoprofen/tramadol 25 mg/75 mg fixed-dose combination vs dexketoprofen (25 mg) and tramadol (100 mg) in moderate-to-severe acute pain after total hip arthroplasty. METHODS This was a randomized, double-blind, parallel-group study in patients experiencing pain of at least moderate intensity on the day after surgery, compared with placebo at first administration to validate the pain model. The study drug was administered orally every 8 h throughout a 5 day period. Rescue medication, metamizole 500 mg, was available during the treatment period. The evaluation of efficacy was based on patient assessments of pain intensity and pain relief. The primary end point was the mean sum of the pain intensity difference values throughout the first 8 h (SPID8). RESULTS Overall, 641 patients, mean age 62 (range 29-80) yr, were analysed; mean (sd) values of SPID8 were 247 (157) for dexketoprofen/tramadol, 209 (155) for dexketoprofen, 205 (146) for tramadol, and 151 (159) for placebo. The primary analysis confirmed the superiority of the combination over dexketoprofen 25 mg (P=0.019; 95% confidence interval 6.4-73) and tramadol 100 mg (P=0.012; 95% confidence interval 9.5-76). The single components were superior to placebo (P<0.05), confirming model sensitivity. Most secondary analyses supported the superiority of the combination. The incidence of adverse drug reactions was low and similar among active treatment groups. CONCLUSION The efficacy results confirmed the superiority of dexketoprofen/tramadol over its single components, even at higher doses (tramadol), with a safety profile fully in line with that previously known for these agents in monotherapy.
