A Rapid Advice Guideline for the Prevention of Novel Coronavirus Through Nutritional Intervention.
Ontology highlight
ABSTRACT: Purpose of review
An unexpected and sudden outbreak of a novel infection known as a coronavirus (COVID-19) has imposed important problems to global well-being and economy. Based upon current researches, this virus is spreading from one human to another through respiratory droplets, i.e. cough and sneeze. Till now, there has not been any specific treatment found for this virus. Hence, there is a critical need to discover alternative techniques to cope with the current scenario.Recent findings
This review conducted an online search for prevention of coronavirus infection with the help of nutritional interventions. It has been observed that the effect of the virus is mostly on the individual with low immunity, individual affected with diseases like diabetes, and individual using any immune-suppressed drug or having past history of major surgeries or severe medical conditions. Therefore, consuming foods which boost immunity helps in preventing respiratory-related disorder or suppressing diseases-related problems, which could be helpful in controlling the spread of this virus. In conclusion, it has been suggested that before the beginning of generalised treatments and interventions in each infected patient, nutritional status should be evaluated, as it can help in creating a specific nutrition intervention for the infected individual.

Project description:In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province; and then named "2019 novel coronavirus (2019-nCoV)" by the World Health Organization (WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world's attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development; we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control (including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.

Project description:BackgroundEmerging evidence shows that severe coronavirus disease 2019 (COVID-19) can be complicated by a significant coagulopathy, that likely manifests in the form of both microthrombosis and VTE. This recognition has led to the urgent need for practical guidance regarding prevention, diagnosis, and treatment of VTE.MethodsA group of approved panelists developed key clinical questions by using the PICO (Population, Intervention, Comparator, Outcome) format that addressed urgent clinical questions regarding the prevention, diagnosis, and treatment of VTE in patients with COVID-19. MEDLINE (via PubMed or Ovid), Embase, and Cochrane Controlled Register of Trials were systematically searched for relevant literature, and references were screened for inclusion. Validated evaluation tools were used to grade the level of evidence to support each recommendation. When evidence did not exist, guidance was developed based on consensus using the modified Delphi process.ResultsThe systematic review and critical analysis of the literature based on 13 Population, Intervention, Comparator, Outcome questions resulted in 22 statements. Very little evidence exists in the COVID-19 population. The panel thus used expert consensus and existing evidence-based guidelines to craft the guidance statements.ConclusionsThe evidence on the optimal strategies to prevent, diagnose, and treat VTE in patients with COVID-19 is sparse but rapidly evolving.

Project description:BackgroundApproximately 20% of older people are readmitted to the hospital within 30 days of discharge. Even a short hospital stay decreases the ability to cope with the activities of daily living. The aims of this study were to (1) assess the feasibility of recruitment, (2) assess the acceptability of the intervention, and (3) investigate if an individual nutritional intervention could reduce the readmission rate of geriatric patients within 30 days of being discharged to their own homes.MethodsThe unblinded, randomized, controlled pilot trial includes geriatric patients discharged to their own homes. Forty patients were recruited from a medical ward and randomized to standard treatment (n = 19) or individualized nutritional intervention (n = 21). The intervention was dietary counseling and a nutrition plan before discharge, combined with two home visits performed by an educated nutritionist over a period of 4 weeks. Outcomes were readmission (primary), mortality, protein and energy intake, body weight, activity of daily living, handgrip strength, number of chair stands, and quality of life. Intention-to-treat analysis, per-protocol analysis, and post hoc analysis of readmissions were carried out.ResultsRecruitment was feasible, and there was high compliance to the intervention. There was no difference in readmission between the intervention group and control group 30 days after discharge (29% vs 11%). The individual nutritional intervention had a positive impact on achieving 75% of energy requirements at 30 days for the intervention group compared to the control group (93% vs 47%, p = 0.01). No other differences were found between the groups.ConclusionThe individual nutritional intervention did not prevent readmission among geriatric patients in this trial. Recruitment procedures functioned well, and the intervention was well accepted by the patients.Trial registrationClinicalTrial.gov, NCT03519139 . Retrospectively registered on 8 May 2018.

Project description:Emerging health problems require rapid advice. We describe the development and pilot testing of a systematic, transparent approach used by the World Health Organization (WHO) to develop rapid advice guidelines in response to requests from member states confronted with uncertainty about the pharmacological management of avian influenza A (H5N1) virus infection. We first searched for systematic reviews of randomized trials of treatment and prevention of seasonal influenza and for non-trial evidence on H5N1 infection, including case reports and animal and in vitro studies. A panel of clinical experts, clinicians with experience in treating patients with H5N1, influenza researchers, and methodologists was convened for a two-day meeting. Panel members reviewed the evidence prior to the meeting and agreed on the process. It took one month to put together a team to prepare the evidence profiles (i.e., summaries of the evidence on important clinical and policy questions), and it took the team only five weeks to prepare and revise the evidence profiles and to prepare draft guidelines prior to the panel meeting. A draft manuscript for publication was prepared within 10 days following the panel meeting. Strengths of the process include its transparency and the short amount of time used to prepare these WHO guidelines. The process could be improved by shortening the time required to commission evidence profiles. Further development is needed to facilitate stakeholder involvement, and evaluate and ensure the guideline's usefulness.

Project description:Obesity and depression are two prevalent conditions that are costly to individuals and society. The bidirectional association of obesity with depression, in which unhealthy dietary patterns may play an important role, has been well established. Few experimental studies have been conducted to investigate whether supplementing specific nutrients or improving diet and food-related behaviors can prevent depression in overweight persons.The MooDFOOD prevention trial examines the feasibility and effectiveness of two different nutritional strategies [multi-nutrient supplementation and food-related behavioral change therapy (FBC)] to prevent depression in individuals who are overweight and have elevated depressive symptoms but who are not currently or in the last 6 months meeting criteria for an episode of major depressive disorder (MDD). The randomized controlled prevention trial has a two-by-two factorial design: participants are randomized to daily multi-nutrient supplement (omega-3 fatty acids, calcium, selenium, B-11 vitamin and D-3 vitamin) versus placebo, and/or FBC therapy sessions versus usual care. Interventions last 12 months. In total 1000 participants aged 18-75 years with body mass index between 25-40 kg/m(2) and with a Patient Health Questionnaire-9 score???5 will be recruited at four study sites in four European countries. Baseline and follow-up assessments take place at 0, 3, 6, and 12 months. Primary endpoint is the onset of an episode of MDD, assessed according to DSM-IV based criteria using the MINI 5.0 interview. Depressive symptoms, anxiety, food and eating behavior, physical activity and health related quality of life are secondary outcomes. During the intervention, compliance, adverse events and potentially mediating variables are carefully monitored.The trial aims to provide a better understanding of the causal role of specific nutrients, overall diet, and food-related behavior change with respect to the incidence of MDD episodes. This knowledge will be used to develop and disseminate innovative evidence-based, feasible, and effective nutritional public health strategies for the prevention of clinical depression.ClinicalTrials.gov.

Project description:Background: Central obesity is associated with a higher risk of disease. Previously yoga reduced the BMI and waist circumference (WC) in persons with obesity. Additional anthropometric measures and indices predict the risk of developing diseases associated with central obesity. Hence the present study aimed to assess the effects of 12 weeks of yoga or nutritional advice on these measures. The secondary aim was to determine the changes in quality of life (QoL) given the importance of psychological factors in obesity. Material and Methods: Twenty-six adult females with central obesity in a yoga group (YOG) were compared with 26 adult females in a nutritional advice group (NAG). Yoga was practiced for 75 min/day, 3 days/week and included postures, breathing practices and guided relaxation. The NAG had one 45 min presentation/week on nutrition. Assessments were at baseline and 12 weeks. Data were analyzed with repeated measures ANOVA and post-hoc comparisons. Age-wise comparisons were with t-tests. Results: At baseline and 12 weeks NAG had higher triglycerides and VLDL than YOG. Other comparisons are within the two groups. After 12 weeks NAG showed a significant decrease in WC, hip circumference (HC), abdominal volume index (AVI), body roundness index (BRI), a significant increase in total cholesterol and LDL cholesterol. YOG had a significant decrease in WC, sagittal abdominal diameter, HC, BMI, WC/HC, a body shape index, conicity index, AVI, BRI, HDL cholesterol, and improved QoL. With age-wise analyses, in the 30-45 years age range the YOG showed most of the changes mentioned above whereas NAG showed no changes. In contrast for the 46-59 years age range most of the changes in the two groups were comparable. Conclusions: Yoga and nutritional advice with a diet plan can reduce anthropometric measures associated with diseases related to central obesity, with more changes in the YOG. This was greater for the 30-45 year age range, where the NAG showed no change; while changes were comparable for the two groups in the 46-59 year age range. Hence yoga may be especially useful for adult females with central obesity between 30 and 45 years of age.Trial registration(CTRI/2018/05/014077).

Project description:Low levels of public knowledge, incorrect beliefs, and anxiety are the most often mentioned factors that may negatively affect the implementation of preventive campaigns and timely diagnosis of cancer. Cancer is a major unresolved problem for global public health. As a result, many effective preventive measures need to be found and implemented. For a duration of 18 months, readers of the Polish scientific Internet portal were invited to participate in the Polish On-line Randomized Intervention aimed at Neoplasm Avoidance (PORINA) study. Level of cancer-related anxiety was our main measure (self-declared on a simple five-point Likert scale) in this analysis. A total of 463 participants were qualified for the final analysis. Respondents with a positive family history of cancer (p < 0.001) declared the highest level of cancer-related anxiety, whereas lower levels were declared by those previously treated for cancer (p = 0.006). The conducted educational intervention reduced the declared level of cancer-related anxiety. The results of this study provide evidence that the use of web-based interventions aimed at increasing awareness could reduce cancer-related anxiety and may lead to more frequent consent to undergo some of the medical procedures used to diagnose or treat cancer.

Project description:Interventions: Group 1: Patients diagnosed with colorectal cancer aged 18-49 years
Group 2: Comparators without colorectal cancer aged 18-49 years
Primary outcome(s): Specific goals of the individual sub-projects of the OUTLIVE study
Sub-project 3
This sub-project (SP) aims to decipher mechanisms of diet-related metabolic product (metabolite) patterns and their influence on biological aging processes in the context of colorectal carcinogenesis. The data from the metabolome analyzes will be combined with microbiome, epigenome, genome and proteome data from the same analyzed samples from the other sub-projects (TP4-6) to generate a meta-dataset (TP7). This data set should enable a prediction of the biological age and the risk of recurrence in chronologically young CRC patients in an automated test (TP8). Together with the results from TP9, the question should be answered whether the difference between chronological and biological age is driven by nutrition and can be prevented by personalized nutritional intervention in order to avoid relapses, especially in chronologically young CRC patients. To investigate the functional consequences of diet-related metabolic conditions on tumor development in the colon, AP1 will generate intestinal 3D organoids from colon biopsies obtained from non-CRC patients (irritable bowel syndrome, celiac disease, food hypersensitivity, etc.). In addition, the body composition of the examined patients is monitored by a bio-impedance analysis before the endoscopy. The long-term observation and diet type determination of the metabolism of the non-CRC patients examined is carried out as part of TP9 in close cooperation with Perfood GmbH. The 3D human colon organoids are then cultured under different metabolic conditions. Malignant transformation of 3D organoids is analyzed by examining proliferation, differentiation and metabolism using real-time cell analysis, fluorescence microscopy, immunohistochemistry, Western blot, qPCR and flow cytometry. In AP2, serum samples from CRC (TP1) or non-CRC patients (AP1) will be used for NMR-based metabolome analysis. The metabolome data of the non-CRC patients are supplemented by clinical parameters (blood sugar, insulin, HbA1c, vitamins, CRP, leukocyte count, etc.), which are determined in TP9 before the endoscopy. At the same time, stool samples are collected to examine the intestinal inflammation (faecal blood, calprotectin, C3 and IgA). These data will be correlated with the composition of the faecal microbiome (TP4).
Sub-project 4
The aim of TP4 is to identify new epigenomic and microbiomic markers for the earlier detection of the CRC in plasma and stool samples from individuals in a defined cohort of subjects (TP1, TP3). Here, the methylation pattern of cfDNA samples from young CRC patients and cfDNA samples from non-CRC patients (TP3 & TP9) will be recorded. In parallel, the composition of the microbiome in stool samples from the same individuals will be determined using 16S rRNA sequencing. The markers obtained are to be prioritized by bioinformatic analyzes in cooperation with the partners in TP3, TP5, TP6 and TP7 with regard to their diagnostic potential and included in the Multimarker Panel (TP8).TP4 is divided into three work packages (AP). In WP1, enrichment-based sequencing methods are used to identify 5mC regions. AP2 will perform PCR-based amplifications of variable regions (V3, V4) of microbial 16S rRNA coupled with multiplex high-throughput sequencing (NGS) to determine the microbiome. The bioinformatic analysis of this data is carried out continuously in WP3 and in close cooperation with TP7. The data will later be validated in an independent sample collection at the level of the multimarker panel (TP8).
Sub-project 5
The goal of TP5 is the development of biomarkers for patients with curative treatment. In phase 1, patients who cannot be treated curatively are initially included for clinical validation. In phase 1, patients with CRC up to 50 years of age will be screened using dPCR and targeted NGS with plasma samples obtained at the time of diagnosis and before the start of treatment OR at the time of relapse or progression after treatment examined for tumor-specific mutations. In addition, healthy control plasma samples (TP3 & TP9) are analyzed in an analogous manner. Phase 2 will focus on patients with intended curative treatment. Here, plasma samples from CRC patients are analyzed at the following time points: at diagnosis before starting treatment; after completion of treatment and at the time of relapse. In addition, healthy controls (TP3 & TP9) are analyzed.
Sub-project 6
Biological age-based proteome analysis aims to (a) provide biomarkers for (re)establishment of health, (b) uncover early indicators of disease recurrence, (c) define the optimal metabolism of the healthy phenotype and (d) to help distinguish dietary responders from non-responders. The long-term result is personalized nutrition to maintain individual health in young adults with colorectal cancer. TP6 is divided into the following work packages reflecting the different human sample entities:
• WP1: Proteome analysis of serum/plasma samples (TP1 & TP3/TP9)
• WP2: Proteome analysis of organoids (TP3)
• WP4: Proteome analysis of sample preparation experiments (TP8)
For relative protein quantification, LC-ESI-MS/MS is used in data-independent (DIA/SWATH) mode in all APs. DIA/SWATH uses variable mass windows to enable complete measurement of all detectable proteins in a sample, i.e. identification and quantification of thousands of proteins in just one measurement.
Sub-project 7
The goals of TP7 are divided into 4 work packages. WP1 is to set up a central data repository for all research data according to FAIR principles with controlled access, WP2 is to install standardized data analysis. WP3 aims to develop a liquid biopsy-based multi-omics biomarker for the early diagnosis and monitoring of CRC. WP4 aims to support the development of marker panels, nutritional interventions and patient monitoring. In the first phase, years 1-4, TP7 will build the computational infrastructure and focus on the computational development of a CRC biomarker panel based on CRC, control and organoid samples together with clinical data. In the second phase, TP7 will support the translation of the marker panel into clinical practice and provide computational support for nutritional intervention (TP9) and long-term patient monitoring.
Sub-project 9
Screening and optimization for optimal nutrition to prevent biological intestinal aging. In a first step, the influence of various nutritional interventions on the biological age of the intestine will be investigated in an exploratory pilot study. The underlying hypothesis is that biological age is causally involved in the development of CRC. For this purpose, together with TP3, healthy volunteers <50 years will be recruited and included in study 1 (screening). Biomaterials including primary intestinal stem cells for organoid cultivation (TP3) as well as for metabolic characterization (TP3) will be obtained from these subjects. The subjects go through a 14-day, digitally accompanied test phase with test meals and constant glucose monitor (CGM) analysis. This is part of the MillionFriends program offered by the participating KMU Perfood GmbH. This is followed by a 6-month intervention phase (healthy diet according to national guidelines vs. low-GI vs. reduced-calorie intermittent fasting), followed by a final endoscopy including biomaterial collection. The aim is to find out whether and if so, which of the tested nutritional interventions have a positive influence on the biological age in the intestine. The most effective intervention with regard to the primary endpoint serves as a comparison group and as a basis for establishing an optimized diet that takes up the results of TP3.
