Childhood neglect, the neglected trauma. A systematic review and meta-analysis of its prevalence in psychiatric disorders.

Traumatic events increase risk of mental illnesses, but childhood neglect prevalence in psychiatric disorders is understudied. This systematic review and meta-analysis assessed neglect prevalence, including emotional neglect (EN) and physical neglect (PN), among adults with psychiatric disorders. We conducted a systematic search and meta-analysis in 122 studies assessing different psychiatric disorders. Prevalence was 46.6% (95%CI[34.5-59.0]) for unspecified neglect (Ne), 43.1% (95%CI[39.0-47.4]) for EN, and 34.8% (95%CI[30.6-39.2]) for PN. Although a moderating effect of the psychiatric diagnostic category was not confirmed, some clinical diagnoses had significantly lower prevalence rates than others. Patients with bipolar disorder and major depressive disorder showed lower prevalence rates of EN and PN, whereas lower prevalence was found in psychotic disorders and eating disorders for PN only. Neglect assessment was a significant moderator for Ne and PN. No moderating effect of age and sex on neglect prevalence was found. Heterogeneity levels within and between psychiatric diagnostic categories remained high. This is the first meta-analysis examining diverse types of neglect prevalence considering different psychiatric diagnoses. Our results explore the prevalence of childhood neglect and its subtypes among adults with psychiatric disorders, contributing to understanding the nuanced interplay between neglect and specific psychiatric conditions, and guiding interventions for affected individuals.

Different greenness exposure in Europe and respiratory outcomes in youths. A systematic review and meta-analysis.

The existing evidence on the association between greenness and respiratory outcomes remains inconclusive. We aimed at systematically summarizing existing literature on greenness exposure and respiratory outcomes in European children and adolescents, with a preliminary attempt to qualify the distribution of dominant tree species across different geographical areas and bioclimatic regions. Overall, 4049 studies were firstly identified by searching PubMed/MEDLINE, EMBASE, Scopus, Web of Science, GreenFile and CAB direct, up to 29 August 2023. Eighteen primary studies were included in the systematic review and six were meta-analyzed. No overall significant association was observed between the Normalized Difference Vegetation Index, assessed within 500-m buffers (i.e. NDVI-500), and the odds of asthma for 0.3-increase in the exposure (OR: 0.97, 95% CI from 0.53 to 1.78). Similarly, an overall exposure to the NDVI-300 highest tertile, as compared to the lowest tertile, was not significantly associated with asthma (OR: 0.65, 95% CI from 0.22 to 1.91): heterogeneity among studies was significant (p = 0.021). We delineated some key elements that might have mostly contributed to the lack of scientific consensus on this topic, starting from the urgent need of harmonized approaches for the operational definition of greenness. Additionally, the complex interplay between greenness and respiratory health may vary across different geographical regions and climatic conditions. At last, the inconsistent findings may reflect the heterogeneity and complexity of this relationship, rather than a lack of scientific consensus itself. Future research should compare geographical areas with similar bioclimatic parameters and dominant or potentially present vegetation species, in order to achieve a higher inter-study comparability.

Biomarkers of oxidative stress, inflammation, and genotoxicity to assess exposure to micro- and nanoplastics. A literature review.

The increased awareness about possible health effects arising from micro- and nanoplastics (MNPs) pollution is driving a huge amount of studies. Many international efforts are in place to better understand and characterize the hazard of MNPs present in the environment. The literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology in two different databases (PubMed and Embase). The selection of articles was carried out blind, screening titles and abstracts according to inclusion and exclusion criteria. In general, these studies rely on the methodology already in use for assessing hazard from nanomaterials and particles of concern. However, only a limited number of studies have so far directly measured human exposure to MNPs and examined the relationship between such exposure and its impact on human health. This review aims to provide an overview of the current state of research on biomarkers of oxidative stress, inflammation, and genotoxicity that have been explored in relation to MNPs exposure, using human, cellular, animal, and plant models. Both in-vitro and in-vivo models suggest an increased level of oxidative stress and inflammation as the main mechanism of action (MOA) leading to adverse effects such as chronic inflammation, immunotoxicity and genotoxicity. With the identification of such biological endpoints, representing critical key initiating events (KIEs) towards adaptive or adverse outcomes, it is possible to identify a panel of surrogate biomarkers to be applied and validated especially in occupational settings, where higher levels of exposure may occur.

Viruses and Human Milk: Transmission or Protection?

Human milk (HM) is considered the best source of nutrition for infant growth and health. This nourishment is unique and changes constantly during lactation to adapt to the physiological needs of the developing infant. It is also recognized as a potential route of transmission of some viral pathogens although the presence of a virus in HM rarely leads to a disease in an infant. This intriguing paradox can be explained by considering the intrinsic antiviral properties of HM. In this comprehensive and schematically presented review, we have described what viruses have been detected in HM so far and what their potential transmission risk through breastfeeding is. We have provided a description of all the antiviral compounds of HM, along with an analysis of their demonstrated and hypothesized mechanisms of action. Finally, we have also analyzed the impact of HM pasteurization and storage methods on the detection and transmission of viruses, and on the antiviral compounds of HM. We have highlighted that there is currently a deep knowledge on the potential transmission of viral pathogens through breastfeeding and on the antiviral properties of HM. The current evidence suggests that, in most cases, it is unnecessarily to deprive an infant of this high-quality nourishment and that the continuation of breastfeeding is in the best interest of the infant and the mother.

The Effect of Dietary Patterns and Nutrient Intake on Oxidative Stress Levels in Pregnant Women: A Systematic Review.

During pregnancy, reactive oxygen species (ROS) may physiologically increase due to changes and growth of mother and fetal tissues. Consequently, oxidative stress (OS) may occur and be involved in the onset of pregnancy and newborn complications. Among exogenous antioxidant sources, diet is a cost-effective prevention strategy supporting the health of mothers and newborns; however, there is still a lack of nutritional education during pregnancy interviews. This review aims to systematically summarize the knowledge on the association between OS and diet during pregnancy. Four electronic databases (PubMed Central, EMBASE, Web of Science, and Food Science and Technology Abstracts) were searched on 22 December 2022. Among 4162 records, 13 original articles were finally included. Overall, 80% of the studies considered dietary patterns as exposure and 60% of them assessed the association with malondialdehyde levels in blood and urine. Three studies analyzed the influence of daily intakes of fruit and vegetables on different OS biomarkers (malondialdehyde, nitric oxide and 8-hydroxy-2'-deoxyguanosine). Among studies exploring dietary fat intakes (39%), 80% focused on polyunsaturated fatty acids, finding a positive association with glutathione peroxidase, biopirryn and isoprostane levels, respectively. Four studies analyzed vitamin intakes and 50% of them in association with 8-hydroxy-2'-deoxyguanosine.

Inflammatory Biomarkers in Exhaled Breath Condensate: A Systematic Review.

Inflammation is a comprehensive set of physiological processes that an organism undertakes in response to a wide variety of foreign stimuli, such as viruses, bacteria, and inorganic particles. A key role is played by cytokines, protein-based chemical mediators produced by a broad range of cells, including the immune cells recruited in the inflammation site. The aim of this systematic review is to compare baseline values of pro/anti-inflammatory biomarkers measured in Exhaled Breath Condensate (EBC) in healthy, non-smoking adults to provide a summary of the concentrations reported in the literature. We focused on: interleukin (IL)-1ß, IL-4, IL-6, IL-8, IL-10, tumour necrosis factor-alpha (TNF-α), and C reactive protein (CRP). Eligible articles were identified in PubMed, Embase, and Cochrane CENTRAL. Due to the wide differences in methodologies employed in the included articles concerning EBC sampling, storage, and analyses, research protocols were assessed specifically to test their adherence to the ATS/ERS Task Force guidelines on EBC. The development of reference intervals for these biomarkers can result in their introduction and use in both research and clinical settings, not only for monitoring purposes but also, in the perspective of future longitudinal studies, as predictive parameters for the onset and development of chronic diseases with inflammatory aetiology.

Non-Invasive Measurement of Exercise-Induced Oxidative Stress in Response to Physical Activity. A Systematic Review and Meta-Analysis.

Physical activity may benefit health by modulating oxidative stress and inflammation. However, the selection of suitable exercise-induced oxidative stress biomarkers is still challenging. This study aimed at systematically summarizing the available evidence on exercise-induced oxidative stress measured in urine and/or saliva. Two meta-analyses including the most frequently quantified biomarkers of oxidative stress, namely, urinary isoprostane and DNA oxidation products, were performed. Three electronic databases (PubMed, EMBASE and Cochrane CENTRAL) were interrogated. Among 4479 records, 43 original articles were included in the systematic review and 11 articles were included in meta-analysis I and II, respectively. We observed a pooled trend of increase of urinary isoprostanes in response to physical activity (+0.95, 95% CI: -0.18; 2.09). In comparison with aerobic exercise, anaerobic training determined a greater induction of isoprostanes (+5.21, 95% CI: 2.76; 7.66, p < 0.0001), which were markedly increased after vigorous physical activity (+6.01, 95% CI: 1.18; 10.84, p < 0.001) and slightly decreased in response to exercise interventions protracted over time (e.g., months) (-1.19, 95% CI: -2.25; -0.12, p < 0.001). We recommend the most integrative approach of oxidative stress multi-marker panels in response to physical activity instead of selecting one preferential biomarker to quantify physical activity-induced oxidative stress in humans.

The efficacy of mindfulness-based interventions in attention-deficit/hyperactivity disorder beyond core symptoms: A systematic review, meta-analysis, and meta-regression.

BACKGROUND: Mindfulness-Based Interventions (MBIs) have been increasingly proposed as treatment in patients with Attention-Deficit/Hyperactivity Disorder (ADHD), showing promising results on different proposed outcomes, in both children and adults. OBJECTIVES: To systematically review and meta-analyse studies concerning the effects of MBIs on either ADHD and associated features, associated clinical conditions, neurocognitive impairments, mindfulness skills, global functioning and quality of life. METHODS: Searches were conducted on five databases, including controlled and observational studies on both adults and children populations. The review process was compliant to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Meta-analyses and meta-regression models were conducted. RESULTS: Thirty-one full-texts were included. In both adults and children, MBIs showed to be more effective than waiting lists in improving ADHD symptoms and some other outcomes. In adults, a medium pooled effect size was shown by meta-analysis for ADHD symptoms but in some cases a publication bias was detected. Subgroup analysis and meta-regression confirmed the gap detected by our systematic review between the medium/large effect size of inactive-controlled studies and the low/negligible one of active-controlled studies. In children, no active-controlled studies have been conducted. Mindfulness Awareness Practice (MAP) and Mindfulness Based Cognitive Therapy (MBCT) were the most used protocols in adult studies, whereas a combination of MBCT and Mindfulness Based Stress Reduction (MBSR) was more preferred for children and adolescent patients. CONCLUSIONS: Even if further studies with a better methodology are needed, we can suggest the MBIs may be useful as complementation and not as replacement of other active interventions.

Serotoninergic brain dysfunction in neuroendocrine tumor patients: A scoping review.

INTRODUCTION: Neuroendocrine tumors (NETs) are rare and malignant neoplasms characterized by their potential to produce metabolically active substances with the capacity to bring about clinical syndromes. The clinical expression of serotonin-producing NETs is known as carcinoid syndrome (CS). The synthesis of serotonin in the brain is dependent on tryptophan availability. At the central level, serotonin is indispensable for mood, anxiety, and sleep regulation. In CS patients, around 60% of all tryptophan is reported to be consumed by tumor cells for the peripheral synthesis of serotonin, increasing the risk of a central deficiency and thus psychiatric disorders. MATERIALS AND METHODS: This manuscript reviews the existing literature about psychiatric disorders associated with NETs and addresses the safety of psychiatric drugs in these patients. A systematic search of the biomedical literature was performed using the following databases: PubMed, Embase, CINAHL (EBSCO), PsycInfo (OVID), and Cochrane CENTRAL (Wiley). The database search included articles published between January 1965 and February 2021. Relevant information were charted using a calibrated charting-form. RESULTS: Twenty-two articles were included in the present review. The overall population size of the studies came to 3319 patients. All patients presented a confirmed diagnosis of NET. The information about the presence of CS was confirmed in 351 cases. The psychiatric symptoms reported included mood disturbances (including, depression and anxiety), psychoses, impulse control disorders and sleeping alterations. We also evaluated the presence of cognitive impairments in NET patients. Finally, we summarize the available data regarding the safety of psychiatric drugs in this setting. CONCLUSIONS: Psychiatric disorders among NET patients are poorly recognized, and therefore have received very little research attention. As a result, no standardized algorithm is presently available. Our findings support detailed psychiatric evaluation in NET patients, especially in those presenting CS and symptoms suggestive of psychiatric involvement. Not only do cognitive impairment and psychiatry symptoms negatively impact health-related quality of life in cancer patients, they can also reduce survival rates.

Eye movement desensitization and reprocessing for depression: a systematic review and meta-analysis.

Background: In recent years, eye movement desensitization and reprocessing (EMDR) has been applied to different psychiatric conditions beyond post-traumatic stress disorder (PTSD), and an increasing number of studies have evaluated its effect on depression. To date, no quantitative synthesis of the efficacy of EMDR on depression has been conducted. Objective: To meta-analytically review the studies on EMDR for depression as the primary target for treatment. Method: Studies with a controlled design evaluating the effect of EMDR on depression were searched on six electronic databases (PubMed, Embase, CINAHL, PsycINFO, Cochrane database, and Francine Shapiro Library) and then selected by two independent reviewers. A systematic review and meta-analysis was conducted. Results: Eleven studies were included for qualitative synthesis. Nine studies were included in the meta-analysis, involving 373 participants. The overall effect size of EMDR for depressive symptoms is large (n = 9, Hedges' g = - 1.07; 95%CI [-1.66; - 0.48]), with high heterogeneity (I 2 = 84%), and corresponds to a 'number needed to treat' of 1.8. At follow-up (range 3-6 months), the effect remains significant but moderate (n = 3, Hedges' g = - 0.62; 95%CI [-0.97; - 0.28]; I 2 = 0%). The effect of EMDR compared with active controls is also moderate (n = 7, g = - 0.68; 95%CI [-0.92; - 0.43]; I 2 = 0%). No publication bias was found, although the results are limited by the small number and poor methodological quality of the included studies. Conclusions: Review findings suggest that EMDR may be considered an effective treatment for improving symptoms of depression, with effects comparable to other active treatments. However, findings need to be interpreted in light of the limited number of the studies and their quality. Further research is required to understand the longer-term of effects EMDR in treating depression and preventing depression relapse. Protocol registration: PROSPERO (CRD42018090086).

Antecedentes: En los últimos años, la desensibilización y reprocesamiento por movimientos oculares (EMDR) se ha aplicado a diferentes condiciones psiquiátricas más allá del trastorno de estrés postraumático (TEPT), y un número creciente de estudios ha evaluado su efecto en la depresión. Hasta la fecha, no se ha realizado ninguna síntesis cuantitativa de la eficacia de la EMDR en la depresión.Objetivo: Revisar meta-analíticamente los estudios de EMDR para la depresión como objetivo principal del tratamiento.Método: Se buscaron estudios con un diseño controlado que evaluaran el efecto de la EMDR en la depresión en seis bases de datos electrónicas (PubMed, Embase, CINAHL, PsycINFO, base de datos Cochrane y Francine Shapiro Library) y luego fueron seleccionados por dos revisores independientes. Se realizó una revisión sistemática y un metanálisis.Resultados: Se incluyeron once estudios para la síntesis cualitativa. Se incluyeron nueve estudios en el meta-análisis, con 373 participantes. El tamaño del efecto global de la EMDR para los síntomas depresivos es grande (n = 9, g de Hedges = −1,07; IC del 95% [−1,66; −0,48]), con alta heterogeneidad (I 2 = 84%), y corresponde a un 'número necesario a tratar' de 1,8. En el seguimiento (rango 3-6 meses), el efecto sigue siendo significativo pero moderado (n = 3, g de Hedges = −0,62; IC del 95% [−0,97;-0,28]; I 2 = 0%). El efecto del EMDR en comparación con los controles activos también es moderado (n = 7, g = −0,68; IC del 95% [−0,92;-0,43]; I 2 = 0%). No se encontró ningún sesgo de publicación, aunque los resultados están limitados por el pequeño número y la pobre calidad metodológica de los estudios incluidos.Conclusiones: Los resultados de la revisión sugieren que la EMDR puede considerarse un tratamiento eficaz para mejorar los síntomas de la depresión, con efectos comparables a los de otros tratamientos activos. Sin embargo, los hallazgos deben interpretarse a la luz del número limitado de los estudios y su calidad. Se requiere investigación adicional para comprender los efectos a largo plazo de la EMDR en el tratamiento de la depresión y la prevención de la recaída de la depresión.Registro del protocolo: PROSPERO (CRD42018090086).

Low protein diets in patients with chronic kidney disease: a bridge between mainstream and complementary-alternative medicines?

Dietary therapy represents an important tool in the management of chronic kidney disease (CKD), mainly through a balanced reduction of protein intake aimed at giving the remnant nephrons in damaged kidneys a "functional rest". While dialysis, transplantation, and pharmacological therapies are usually seen as "high tech" medicine, non pharmacological interventions, including diets, are frequently considered lifestyle-complementary treatments. Diet is one of the oldest CKD treatments, and it is usually considered a part of "mainstream" management. In this narrative review we discuss how the lessons of complementary alternative medicines (CAMs) can be useful for the implementation and study of low-protein diets in CKD. While high tech medicine is mainly prescriptive, prescribing a "good" life-style change is usually not enough and comprehensive counselling is required; the empathic educational approach, on which CAMs are mainly, though not exclusively based, may support a successful personalized nutritional intervention.There is no gold-standard, low-protein diet for all CKD patients: from among a relatively vast choice, the best compliance is probably obtained by personalization. This approach interferes with the traditional RCT-based analyses which are grounded upon an assumption of equal preference of treatments (ideally blinded). Whole system approaches and narrative medicine, that are widely used in the study of CAMs, may offer ways to integrate EBM and personalised medicine in the search for innovative solutions respecting individualization, but gaining sound data, such as with partially-randomised patient preference trials.

Type D Personality and Essential Hypertension in Primary Care: A Cross-Sectional Observational Study Within a Cohort of Patients Visiting General Practitioners.

To estimate the relationship between type D personality and essential hypertension among patients visiting their GPs for any health problem, 101 hypertensive and 138 nonhypertensive patients were consecutively recruited and assessed using the Type D Personality Scale (DS14). The predictive value of type D personality was determined using a logistic regression model, taking into account the differences in recognized confounders between groups. Type D personality in the hypertension group was twice as frequent as in the no hypertension group and hypertension was more frequent among type D than non-type D patients. Logistic regression showed a significant predictive value of type D personality for hypertension, adjusting for sex, age, body mass index, family history of hypertension, living condition, education, and employment. Therefore, type D personality was strongly related to hypertension and it was a noteworthy predictor of hypertension in a real-world cohort of primary care patients.

Pregnancy in dialysis patients in the new millennium: a systematic review and meta-regression analysis correlating dialysis schedules and pregnancy outcomes.

BACKGROUND: Advances have been made in the management of pregnancies in women receiving dialysis; however, single-centre studies and small numbers of cases have so far precluded a clear definition of the relationship between dialysis schedules and pregnancy outcomes. The aim of the present systematic review was to analyse the relationship between dialysis schedule and pregnancy outcomes in pregnancies in chronic dialysis in the new millennium. METHODS: Medline-PubMed, Embase and the Cochrane library were searched (1 January 2000-31 December 2014: MESH, Emtree, free terms on pregnancy and dialysis). A separate analysis was performed for case series (more than five cases) and case reports. Meta-regression was performed in case series dealing with the larger subset of haemodialysis (HD) patients; case reports were analysed separately [according to peritoneal dialysis (PD) versus HD; conception before or during dialysis]. RESULTS: We obtained 190 full texts and 25 congress abstracts from 2048 references. We selected 101 full papers and 25 abstracts (36 series; 90 case reports), for a total of 681 pregnancies in 647 patients. In the case series (574 pregnancies in 543 patients), preterm delivery was extremely frequent (83%). Meta-regression analysis showed a relationship between hours of dialysis per week in HD and preterm delivery, and was significant for preterm deliveries (<37 gestational weeks: P = 0.044; r2 = 0.22) and for small for gestational age (SGA) (P = 0.017; r2 = 0.54). SGA was closely associated with the number of dialysis sessions per week (P = 0.003; r2 = 0.84). Case report analysis suggests a lower incidence of SGA on HD versus PD (31 versus 66.7%; P = 0.015). No evidence of an increased risk of congenital abnormality was found in the retrieved papers. CONCLUSIONS: Data on pregnancy on dialysis are heterogeneous but rapidly accumulating; the main determinant of outcomes on HD is the dialysis schedule. The differences between PD and HD should be further analysed.

Chronic dialysis discontinuation: a systematic narrative review of the literature in the new millennium.

INTRODUCTION AND AIMS: Renal function recovery (RFR), defined as the discontinuation of dialysis after 3 months of replacement therapy, is an uncommon occurrence. At a time when the "too early" start of dialysis is in discussion, a systematic review of the literature for cases in which patients recovered renal function after starting dialysis with chronic indications, including single cases and large series, may lead to attention being focused on this interesting issue. METHODS: The search strategy was built in Medline on Pubmed, in EMBASE and in the Cochrane Collaboration (August 2013) combining Mesh, Emtree and free terms: dialysis or hemodialysis, kidney function, renal function and recovery (publication date 2000-2013). The following tasks were performed in duplicate: titles and abstracts were manually screened, the data were extracted: title, author, objective, year, journal, period of study, multi-center, country, type of study. RESULTS: The systematic review retrieved 1,894 titles; 58 full papers were retrieved and the final selection included 24 papers: 11 case series or Registry data (4 from ANZdata) and 13 case reports. In spite of the high heterogeneity of the studies, overall they suggest that RFR occurs in about 1% of patients, without differences between PD and HD. RFR appears to be more frequent in elderly patients with renal vascular disease (up to 10% RFR in cholesterol emboli or scleroderma), but is reported in all types of primary and secondary kidney diseases. CONCLUSIONS: RFR is a clinical event that should be looked for, particularly in elderly patients with vascular comorbidity.

Type 1 diabetes, diabetic nephropathy, and pregnancy: a systematic review and meta-study.

BACKGROUND: In the last decade, significant improvements have been achieved in maternal-fetal and diabetic care which make pregnancy possible in an increasing number of type 1 diabetic women with end-organ damage. Optimal counseling is important to make the advancements available to the relevant patients and to ensure the safety of mother and child. A systematic review will help to provide a survey of the available methods and to promote optimal counseling. OBJECTIVES: To review the literature on diabetic nephropathy and pregnancy in type 1 diabetes. METHODS: Medline, Embase, and the Cochrane Library were scanned in November 2012 (MESH, Emtree, and free terms on pregnancy and diabetic nephropathy). Studies were selected that report on pregnancy outcomes in type 1 diabetic patients with diabetic nephropathy in 1980-2012 (i.e. since the detection of microalbuminuria). Case reports with less than 5 cases and reports on kidney grafts were excluded. Paper selection and data extraction were performed in duplicate and matched for consistency. As the relevant reports were highly heterogeneous, we decided to perform a narrative review, with discussions oriented towards the period of publication. RESULTS: Of the 1058 references considered, 34 fulfilled the selection criteria, and one was added from reference lists. The number of cases considered in the reports, which generally involved single-center studies, ranged from 5 to 311. The following issues were significant: (i) the evidence is scattered over many reports of differing format and involving small series (only 2 included over 100 patients), (ii) definitions are non-homogeneous, (iii) risks for pregnancy-related adverse events are increased (preterm delivery, caesarean section, perinatal death, and stillbirth) and do not substantially change over time, except for stillbirth (from over 10% to about 5%), (iv) the increase in risks with nephropathy progression needs confirmation in large homogeneous series, (v) the newly reported increase in malformations in diabetic nephropathy underlines the need for further studies. CONCLUSIONS: The heterogeneous evidence from studies on diabetic nephropathy in pregnancy emphasizes the need for further perspective studies on this issue.

Reiki and related therapies in the dialysis ward: an evidence-based and ethical discussion to debate if these complementary and alternative medicines are welcomed or banned.

BACKGROUND: Complementary and Alternative Medicines (CAMs) are increasingly practiced in the general population; it is estimated that over 30% of patients with chronic diseases use CAMs on a regular basis. CAMs are also used in hospital settings, suggesting a growing interest in individualized therapies. One potential field of interest is pain, frequently reported by dialysis patients, and seldom sufficiently relieved by mainstream therapies. Gentle-touch therapies and Reiki (an energy based touch therapy) are widely used in the western population as pain relievers.By integrating evidence based approaches and providing ethical discussion, this debate discusses the pros and cons of CAMs in the dialysis ward, and whether such approaches should be welcomed or banned. DISCUSSION: In spite of the wide use of CAMs in the general population, few studies deal with the pros and cons of an integration of mainstream medicine and CAMs in dialysis patients; one paper only regarded the use of Reiki and related practices. Widening the search to chronic pain, Reiki and related practices, 419 articles were found on Medline and 6 were selected (1 Cochrane review and 5 RCTs updating the Cochrane review). According to the EBM approach, Reiki allows a statistically significant but very low-grade pain reduction without specific side effects. Gentle-touch therapy and Reiki are thus good examples of approaches in which controversial efficacy has to be balanced against no known side effect, frequent free availability (volunteer non-profit associations) and easy integration with any other pharmacological or non pharmacological therapy. While a classical evidence-based approach, showing low-grade efficacy, is likely to lead to a negative attitude towards the use of Reiki in the dialysis ward, the ethical discussion, analyzing beneficium (efficacy) together with non maleficium (side effects), justice (cost, availability and integration with mainstream therapies) and autonomy (patients' choice) is likely to lead to a permissive-positive attitude. SUMMARY: This paper debates the current evidence on Reiki and related techniques as pain-relievers in an ethical framework, and suggests that physicians may wish to consider efficacy but also side effects, contextualization (availability and costs) and patient's requests, according also to the suggestions of the Society for Integrative Oncology (tolerate, control efficacy and side effects).

Implementation of Web 2.0 services in academic, medical and research libraries: a scoping review.

BACKGROUND: Academic, medical and research libraries frequently implement Web 2.0 services for users. Several reports notwithstanding, characteristics and effectiveness of services are unclear. OBJECTIVES: To find out: the Web 2.0 services implemented by medical, academic and research libraries; study designs, measures and types of data used in included articles to evaluate effectiveness; whether the identified body of literature is amenable to a systematic review of results. METHODS: Scoping review mapping the literature on the topic. Searches were performed in 19 databases. INCLUSION CRITERIA: research articles in English, Italian, German, French and Spanish (publication date ≥ 2006) about Web 2.0 services for final users implemented by academic, medical and research libraries. Reviewers' agreement was measured by Cohen's kappa. From a data set of 6461 articles, 255 (4%) were coded and analysed. RESULTS: Conferencing/chat/instant messaging, blogging, podcasts, social networking, wikis and aggregators were frequently examined. Services were mainly targeted at general academic users of English-speaking countries. CONCLUSIONS: Data prohibit a reliable estimate of the relative frequency of implemented Web 2.0 services. Case studies were the prevalent design. Most articles evaluated different outcomes using diverse assessment methodologies. A systematic review is recommended to assess the effectiveness of such services.

Effectiveness of bibliographic searches performed by paediatric residents and interns assisted by librarians. A randomised controlled trial.

BACKGROUND: Considerable barriers still prevent paediatricians from successfully using information retrieval technology. OBJECTIVES: To verify whether the assistance of biomedical librarians significantly improves the outcomes of searches performed by paediatricians in biomedical databases using real-life clinical scenarios. METHODS: In a controlled trial at a paediatric teaching hospital, nine residents and interns were randomly allocated to an assisted search group and nine to a non-assisted (control) group. Each participant searched PubMed and other online sources, performing pre-determined tasks including the formulation of a clinical question, retrieval and selection of bibliographic records. In the assisted group, participants were supported by a librarian with ≥5 years of experience. The primary outcome was the success of search sessions, scored against a specific assessment tool. RESULTS: The median score of the assisted group was 73.6 points interquartile range (IQR = 13.4) vs. 50.4 (IQR = 17.1) of the control group. The difference between median values in the results was 23.2 points (95% CI 4.8-33.2), in favour of the assisted group (P-value, Mann-Whitney U test: 0.013). CONCLUSIONS: The study has found quantitative evidence of a significant difference in search performance between paediatric residents or interns assisted by a librarian and those searching the literature alone.
