Fish and human health: an umbrella review of observational studies.

Fish represents one of the most important dietary sources of omega-3 polyunsaturated fatty acids, which are known to be associated with various health benefits. This study aimed to systematically review existing meta-analyses of observational studies exploring the association between fish intake and various health outcomes. A systematic search of electronic databases was conducted to retrieve a total of 63 studies. Evidence was deemed as possible for the association between higher fish intake and decreased risk of the acute coronary syndrome, liver cancer, and depression, and limited for other outcomes (including age-related macular degeneration, Alzheimer's disease, heart failure, all-cause and coronary heart disease mortality, total and ischaemic stroke) due to heterogeneity between results and potential otherwise inexplicable confounding factors. In conclusion, results from epidemiological studies support the mechanistic effects associated with omega-3 fatty acids from high fish consumption, but evidence needs to be further corroborated with more reliable results.

Total, red and processed meat consumption and human health: an umbrella review of observational studies.

Meat consumption has represented an important evolutionary step for humans. However, modern patterns of consumption, including excess intake, type of meat and cooking method have been the focus of attention as a potential cause of rise in non-communicable diseases. The aim of this study was to investigate the association between total, red and processed meat with health outcomes and to assess the level of evidence by performing a systematic search of meta-analyses of prospective cohort studies. Convincing evidence of the association between increased risk of (i) colorectal adenoma, lung cancer, CHD and stroke, (ii) colorectal adenoma, ovarian, prostate, renal and stomach cancers, CHD and stroke and (iii) colon and bladder cancer was found for excess intake of total, red and processed meat, respectively. Possible negative associations with other health outcomes have been reported. Excess meat consumption may be detrimental to health, with a major impact on cardiometabolic and cancer risk.

Nut and legume consumption and human health: an umbrella review of observational studies.

Consumption of nuts and legumes has been associated with several health benefits. The aim of this study was to systematically review existing meta-analyses of observational studies on nut and legume intake and non-communicable diseases, and assess the level of evidence. Out of the six meta-analyses focussed on legume and 15 on nut intake, a possible association with decreased risk of colorectal adenoma and coronary heart disease was found for higher legume consumption, and a decreased risk of cardiovascular and cancer mortality, colon cancer, hypertension and ischaemic stroke for higher nut consumption. The association between legume consumption and cardiovascular diseases (CVDs), as well as nut consumption and risk of cancer, CVD incidence and all-cause mortality, was deemed as "limited" due to heterogeneity between results and/or potential confounding factors. General benefit towards better health can be observed for nut and legume consumption. Further studies are needed to better elucidate potential confounding factors.

Dairy foods and health: an umbrella review of observational studies.

Evidence on consumption of dairy foods and human health is contradictory. This study aimed to summarize the level of evidence of dairy consumption on various health outcomes. A systematic search for meta-analyses was performed: study design, dose-response relationship, heterogeneity and agreement of results over time, and identification of potential confounding factors were considered to assess the level of evidence. Convincing and probable evidence of decreased risk of colorectal cancer, hypertension and cardiovascular disease, elevated blood pressure and fatal stroke, respectively, was found for total dairy consumption; possible decreased risk of breast cancer, metabolic syndrome, stroke and type-2 diabetes, and increased risk of prostate cancer and Parkinson's disease was also found. Similar, yet not entirely consistent evidence for individual dairy products was reported. Among potential confounding factors, geographical localisation and fat content of dairy have been detected. In conclusions, dairy may be part of a healthy diet; however, additional studies exploring confounding factors are needed to ascertain the potential detrimental effects.

Egg consumption and human health: an umbrella review of observational studies.

Egg consumption has been an area of controversy regarding its impact on human health largely due to the content in cholesterol and its potential role in cardio-metabolic outcomes. This study aimed to summarise the level of evidence of egg consumption on various health outcomes. A systematic search for meta-analyses was performed: study design, dose-response relationship, heterogeneity and agreement of results over time, and identification of potential confounding factors were considered to assess the level of evidence. Results from this umbrella review showed a substantial no association between egg consumption and a number of health outcomes, including cancer, cardiovascular and metabolic disorders. In contrast, evidence of possible beneficial effects toward stroke risk has been found. In conclusions, egg may be part of a healthy diet; however, additional studies exploring confounding factors are needed to ascertain the potential detrimental effects.

Whole grain consumption and human health: an umbrella review of observational studies.

Whole grains have been associated with a number of health benefits. We systematically reviewed existing meta-analyses of observational studies and evaluated the level of evidence for their putative effects based on pre-selected criteria. Of the 23 included studies, we found convincing evidence of an inverse association between whole grain consumption and risk of type-2 diabetes and colorectal cancer; possible evidence of decreased risk of colon cancer and cardiovascular mortality with increased whole grain intake, as well as increased risk of prostate cancer. Limited or insufficient evidence was available for all other outcomes investigated. Overall findings are encouraging for a positive effect of whole grain consumption on certain diseases, especially highly prevalent metabolic diseases, however, uncertainty of some negative associations deserves further attention.

Psychometric testing of the Caring Behaviors Inventory for nursing students.

AIM AND OBJECTIVE: To test the psychometric properties of the nursing students' version of the 24-item Caring Behaviours Inventory. BACKGROUND: Caring is at the heart of nursing and should also be a core value in nursing education. Caring can be manifested through measurable behaviours. The Caring Behaviors Inventory is a valid and reliable measure of nurses' caring behaviours in clinical settings. It has already been used among nursing students, but it needs more psychometric testing. DESIGN: Cross-sectional validation study. METHOD: The questionnaire was filled in by 300 undergraduate nursing students at two Italian universities in May 2016. Exploratory factor analysis was conducted using Mplus maximum likelihood with GEOMIN oblique rotation. A multifaceted approach was used to evaluate the model fit. The STROBE checklist for cross-sectional studies was followed. RESULTS: Four dimensions were identified: "being with," "doing with competence," "responding to individual needs" and "providing effective care." Adequate fit indices and high reliability of the factors were found. Correlations between factors were positive and significant. CONCLUSION: This study makes it possible to use the same tool to compare the caring practices perceived by students, nurses and patients. Further studies with bigger samples could be stratified to investigate the associations between caring levels and student characteristics. The Caring Behaviors Inventory can be used to call attention to caring in nursing education, helping to make this concept less elusive. RELEVANCE TO CLINICAL PRACTICE: The effective self-assessment of nursing students' caring behaviours offers opportunities for reflection on their caring practice. This could improve the caring level of their behaviours in clinical practice and help them to become caring nurses in the future.

Fruit and vegetable consumption and health outcomes: an umbrella review of observational studies.

The aim of this study was to provide a comprehensive evaluation of current evidence on fruit and vegetable consumption and health outcomes. A systematic search for quantitative syntheses was performed. Several criteria, including study design, dose-response relationship, heterogeneity and agreement of results over time, and identification of potential confounding factors, were used to assess the level of evidence. The strongest (probable) evidence was found for cardiovascular disease protection; possible evidence for decreased risk of colon cancer, depression and pancreatic diseases was found for fruit intake; and colon and rectal cancer, hip fracture, stroke, depression and pancreatic diseases was found for vegetable intake. Suggestive and rather limited associations with other outcomes have been found. Evidence of potential confounding by sex and geographical localisation has been reported. Despite findings are consistent enough for hypothesising causation (at least for cardiovascular-related outcomes), further studies are needed to clarify the role of potential confounding factors.

A longitudinal study on caring behaviors of Italian nursing students.

AIM AND OBJECTIVE: The aim of this study was to analyze the caring behavioral differences taking place over the nursing academic period. BACKGROUND: Caring is a core value in nursing education and many of its features can be measured as specific behaviors. The Italian Caring Behaviors Inventory is a tested psychometric questionnaire, useful to this aim. The use of the questionnaire facilitates the student's self-reflection and awareness. DESIGN: Descriptive longitudinal study. METHOD: The Italian Caring Behaviors Inventory questionnaire was filled out by 103 undergraduate nursing students at two Italian universities from May 2016 to May 2018 both during the second and the third year course. The questionnaire features 24 items with four caring factors: Factor 1 'Being with', Factor 2 'Doing with competence', Factor 3 'Responding to individual needs', Factor 4 'Providing effective care'. The Wilcoxon signed-rank test was used to assess differences between factors. Multiple regression analyses were conducted in order to evaluate variables associated with the increase or decrease of factors over time. RESULTS: Results show a significant increase in Factor 2 during the selected period, which is positively associated with delta-Factor 1 and delta-Factor 3 and negatively associated with surgery clerkship during the third year of their course. Moreover, there is a significant decrease in Factor 3 between the second and third academic year and the variable positively associated to this decrease is the delta-Factor 4. CONCLUSIONS: One of the main risks of nursing education is an asymmetric impact in favour of doing at the expense of being. In this study, we demonstrated that nursing students reported an increase in instrumental caring and a decrease in expressive caring. These results suggest that a specific training in expressive caring in the third term could be a viable answer to this unmet need in nursing education.

[Multi-ethnic nursing]. / L'Assistenza Infermieristica su base multietnica.

Among the many activities of nurses, the role of intermediary between the client and the health institutions is one of the most important . In this role, nurses may have to deal with cultural conflicts in order to fulfill the requirements of a multi-ethnic client population coming from may different cultures. By adopting an instrument capable of assessing the trans-cultural and inter-cultural knowledge of nurses, it may be possible to fill in any gaps by means of appropriate training or education. The study was performed using an anonymous questionnaire issued to the nurses working in the out-patient structures of the Gynaecological and Maternity Department of the Vittorio Emanuele II Hospital in Catania, which deals with the highest number of non-EEC citizens. The results of the questionnaire indicated that educational intervention to improve knowledge of the principal aspects of transcultural and intercultural nursing , as well as other anthropological and caring aspects was required.
