Definition Of

Several studies have demonstrated that polyphenol-enriched diets may have beneficial effects against the development of degenerative diseases, including atherosclerosis and disorders affecting the central nervous system. This activity has been associated not only with antioxidant and anti-inflammatory properties, but also with additional mechanisms, such as the modulation of lipid metabolism and gut microbiota function. However, long-term studies on humans provided controversial results, making the prediction of polyphenol impact on health uncertain. The aim of this review is to provide an overview and critical analysis of the literature related to the effects of the principal dietary polyphenols on cardiovascular and neurodegenerative disorders. We critically considered and meta-analyzed randomized controlled clinical trials involving subjects taking polyphenol-based supplements. Although some polyphenols might improve specific markers of cardiovascular risk and cognitive status, many inconsistent data are present in literature. Therefore, definitive recommendations for the use of these compounds in the prevention of cardiovascular disease and cognitive decline are currently not applicable. Once pivotal aspects for the definition of polyphenol bioactivity, such as the characterization of pharmacokinetics and safety, are addressed, it will be possible to have a clear picture of the realistic potential of polyphenols for disease prevention.

School Based Interventions

Preventive actions and potential obesity interventions for children are mainly researched throughout the school period, either as part of the school curricula or after regular school hours, via interventions mostly lasting less than 12 months. We aimed to perform a meta-analysis on randomized controlled clinical trials to evaluate the evidence of the efficacy of long-term school-based interventions in the management of childhood obesity in terms of BMI from a dietary and physical activity-based approach. Eleven randomized controlled clinical trials were examined using the random effects model, and the results showed that there were no significant effects associated with physical activity + nutrition intervention in school children aged 6–12 years, with a pooled standardized mean difference (SMD) (95% CI) of −0.00 (−0.05, 0.04). No effects were observed after subgroup analysis based on the intervention length. The findings from our study indicate that long-term school-based interventions on physical activity and dietary habits received by children aged 6–12 years seem to have no effect on BMI. However, the promotion of such interventions should not be discouraged, as they promote additional positive health outcomes for other domains of children’s health.

To the Editor.— The authors of the National Institute of Child Health and Human Development report on neonatal care1 found "important" variations among neonatal intensive care units in philosophies of treatment, methods of treatment, and short-term outcomes. In a recent meta-analysis of follow-up studies,2 researchers document a similarly haphazard approach to the long-term evaluation of very low birth weight survivors. Until randomized controlled clinical trials validate the safety and efficacy of neonatal therapies, and until long-term outcomes are assessed accurately, the treatment of very low birth weight infants should be declared experimental.

We evaluated the impacts of entrainment and impingement at the Salem Generating Station on fish populations and communities in the Delaware Estuary. In the absence of an agreed-upon regulatory definition of “adverse environmental impact” (AEI), we developed three independent benchmarks of AEI based on observed or predicted changes that could threaten the sustainability of a population or the integrity of a community.Our benchmarks of AEI included: (1) disruption of the balanced indigenous community of fish in the vicinity of Salem (the “BIC” analysis); (2) a continued downward trend in the abundance of one or more susceptible fish species (the “Trends” analysis); and (3) occurrence of entrainment/impingement mortality sufficient, in combination with fishing mortality, to jeopardize the future sustainability of one or more populations (the “Stock Jeopardy” analysis).The BIC analysis utilized nearly 30 years of species presence/absence data collected in the immediate vicinity of Salem. The Trends analysis examined three independent data sets that document trends in the abundance of juvenile fish throughout the estuary over the past 20 years. The Stock Jeopardy analysis used two different assessment models to quantify potential long-term impacts of entrainment and impingement on susceptible fish populations. For one of these models, the compensatory capacities of the modeled species were quantified through meta-analysis of spawner-recruit data available for several hundred fish stocks.All three analyses indicated that the fish populations and communities of the Delaware Estuary are healthy and show no evidence of an adverse impact due to Salem. Although the specific models and analyses used at Salem are not applicable to every facility, we believe that a weight of evidence approach that evaluates multiple benchmarks of AEI using both retrospective and predictive methods is the best approach for assessing entrainment and impingement impacts at existing facilities.

Abstract Introduction Lorcaserin is a selective serotonin 2c receptor agonist approved as an anti-obesity agent. The additional cardiometabolic benefits associated with lorcaserin have not been conclusively established. Purpose To examine the effects of lorcaserin on blood pressure, heart rate and other metabolic parameters in overweight or obese patients from randomized controlled clinical trials (RCTs). Methods A literature search was conducted on PubMed, EMBASE, and Cochrane Central using search terms: “lorcaserin”, “Belviq”, and “randomized controlled trials” without language restrictions. RCTs with a follow-up period of at least 24 weeks were included for the meta-analysis. Results Five studies with 9349 patients in the lorcaserin group and 9370 patients in the placebo group were included. Compared with placebo, lorcaserin not only reduced weight (mean difference [MD] = −3.03 kg, 95% CI: −3.42, −2.63, P<0.ehz745.08171, I2 =68%), waist circumference (MD=−2.27 cm, 95% CI: −2.71, −1.83, P<0.ehz745.08171, I2=57%) and BMI (MD=−1.11 kg/m2, 95% CI: −1.27, −0.96, P<0.ehz745.08171, I2=68%), but also improved SBP (MD=−0.75 mmHg, 95% CI: −1.12, −0.38, P<0.0001, I2=0%), DBP (MD=−0.70 mmHg, 95% CI: −0.93, −0.48, P<0.ehz745.08171, I2=0%), heart rate (MD=−0.94 bpm, 95% CI: −1.28, −0.60, P<0.ehz745.08171, I2=0%), LDL (MD=−1.47 mg/dL, 95% CI: −2.21, −0.74, P<0.0001, I2=0%), HDL (MD=0.55 mg/dL, 95% CI: 0.08, 1.01, P=0.02, I2=18%), triglycerides (MD=−8.71 mg/dL, 95% CI: −12.14, −5.28, P<0.ehz745.08171, I2=71%), and fasting plasma glucose (MD=−5.69 mg/L, 95% CI: −9.5, −1.87, P=0.003, I2=93%). Our findings support that lorcaserin has consistent and favourable effects on blood pressure, heart rate, and all criteria of metabolic syndrome. Summary of lorcaserin effects Conclusion Lorcaserin improved all cardiometabolic parameters modestly in addition to its weight loss effect in overweight or obese patients. More research is needed to determine its long-term cardiovascular benefits.

The Relationship

Background: The aging of western societies is leading to a dramatic increase in the prevalence of chronic conditions, threatening the health status and then the sustainability of our healthcare systems. In particular, dementia is being increasingly recognized as a public health priority, given its enormous socioeconomic burdens further amplified by the absence of treatments really effective in improving the clinical course of the disease. Methods: The question of whether some degree of cognitive deterioration is an inevitable part of aging or should be considered as a pathological pre-stage of dementia is currently debated. This is a field in need of research because accelerated brain aging as well as further decline in cognition might be preventable in the early stages of cognitive impairment. Herein, we discuss evidence from clinical and experimental studies on the role of polyphenols in preserving cognitive performance across life. Results: In recent years, the possibility of favorably influencing the cognitive trajectory through promotion of lifestyle modifications has been increasingly investigated. In particular, the relationship between nutritional habits and brain health has attracted special attention. Dietary polyphenols exhibit a strong potential to promote brain due to their efficacy in protecting neurons against oxidative stress-induced injury, suppressing neuroinflammation and in ameliorating cardiovascular risk factor control and cardiovascular function thus counteracting neurotoxicity and neurodegeneration. Conclusion: Emerging evidence suggest that dietary polyphenols, in particular flavonoids, may exert beneficial effects on the central nervous system thus representing a potential tool to preserve cognitive performance throught senescence.

Background: Dietary polyphenols, including flavonoids, have been the focus of major recent attentions due to their wide content in a variety of foods commonly consumed and the findings from numerous studies showing evidence of an association with positive outcomes on human health. Methods: A systematic search using electronic databases PubMed and EMBASE was performed to retrieve English language studies published from the earliest indexing year of each database to April 2019, reporting on the association between dietary flavonoids intake and hypertension. Results: The search strategy resulted in the final selection of 20 studies including 15 cross-sectional investigations and 7 prospective cohorts (1 study reported on 3 prospective cohorts). 5 prospective cohorts, comprising 200,256 individuals and 45,732 cases of hypertension were included in the quantitative analysis. Analysis by extreme quantiles of intake of flavonoid showed a non-significant association with decreased risk of hypertension (RR (risk ratio): 0.96, 95% CI (confidence interval): 0.89, 1.03). Taking into consideration individual flavonoid subclasses, dietary anthocyanins intake was associated with 8% reduction in risk of hypertension, when comparing highest vs. lowest exposure (RR: 0.92, 95% CI: 0.88, 0.97). Conclusions: Further studies are needed to strengthen the retrieved association between anthocyanins consumption and decreased risk of hypertension and clarify whether total flavonoids or rather individual subclasses may exert beneficial effects on blood pressure.

The Subject

Objectives. This article presents a review on the concerned topics and some considerations related to the concept of splinting teeth and implants in the rehabilitation of partial edentulism.Study Selection. An electronic PubMed/MEDLINE and manual search of identified articles and reviews as well as clinical, laboratory, and finite element studies was performed in this project. Due to the shortage in within-subject, long term, randomized, controlled clinical trials regarding the subject a meta-analysis was not possible.Results. Although surrounded with some controversy, joining teeth and implants during the rehabilitation of partial edentulism provides the clinicians with more treatment options where proprioception and bone volume are maintained and distal cantilevers and free end saddles are eliminated. It makes the treatment less complex, of less cost, and more acceptable for the patient.Conclusions. Whenever suitable and justified, combining implant and tooth support might be recommended as an alternative during rehabilitation of partial edentulism. Based on the literature, clinical tips and suggestions were recommended to increase the success of this treatment.

We look back at the end of what soon will be seen as an historic year, from COVID-19 to real-world introduction of biologicals influencing the life of our patients. This review describes the important findings in Rhinology over the past year. A large body of evidence now demonstrates loss of sense of smell to be one of the most common symptoms of COVID-19 infection; a meta-analysis of 3563 patients found the mean prevalence of self-reported loss to be 47%. A number of studies have now shown long-term reduced loss of smell and parosmia. Given the high numbers of people affected by COVID-19, even with the best reported recovery rates, a significant number worldwide will be left with severe olfactory dysfunction. The most prevalent causes for olfactory dysfunction, besides COVID-19 and upper respiratory tract infections in general, are trauma and CRSwNP. For these CRSwNP patients a bright future seems to be starting with the development of treatment with biologics. This year the Nobel prize in Medicine 2021 was awarded jointly to David Julius and Ardem Patapoutian for their discoveries of receptors for temperature and touch which has greatly enhanced our understanding of nasal hyperreactivity and understanding of intranasal trigeminal function. Finally, a new definition of chronic rhinitis has been proposed in the last year and we have seen many papers emphasizing the importance of endotyping patients in chronic rhinitis and rhinosinusitis in order to optimise treatment effect.

AbstractMultiple sclerosis (MS) is an autoimmune disease of the central nervous system, predominantly affecting women of childbearing age. Therefore, issues of conception, pregnancy, and delivery are of significant importance to patients and treating physicians. We discuss immunologic and clinical effects of pregnancy on the course of MS including both immunosuppression on a local level and a heightened state of immunocompetence on a global level. Clinical outcomes of the Pregnancy in Multiple Sclerosis trials are reported. We analyze and update the available data on safety and efficacy of immunomodulating MS treatments and symptomatic treatments for pregnant and lactating women, and address specific issues of MS management at the time of pregnancy. We review the data related to estrogen-based MS therapies currently or previously in trials. Pregnancy does not appear to be associated with adverse outcomes in MS patients. Some evidence suggests possible beneficial effects, although clear prospective data of sufficient length and quality are limited. Long-term relapse rates or disability progression do not seem to be affected by pregnancy in MS patients. The use of immunosuppressive or immunomodulatory agents in pregnancy is not routinely advisable but could be considered under special circumstances.
