Plasma Nickel Levels Correlate with Low Muscular Strength and Renal Function Parameters in Patients with Prostate Cancer.

Nickel is associated with cancer in occupational exposure. However, few studies have been devoted to analyzing the effects of nickel at environmental concentrations in cancer patients. In this work, the concentration of nickel in blood samples from patients with prostate cancer (PCa) was evaluated because this metal displays androgenic and estrogenic effects that play a crucial role in prostate carcinogenesis and treatment. We, therefore, compared blood nickel concentration in patients with PCa (non-occupationally exposed) (n = 46) with those in control age-matched individuals (n = 46). We also analyzed if there was any association between sociodemographic factors, clinical variables, geriatric evaluation assessment results, blood cell counts, or biochemical, androgen and estrogen concentrations. Using inductively coupled plasma-mass spectroscopy on the plasma samples, we observed a mean nickel level of 4.97 ± 1.20 µg/L in the PCa group and 3.59 ± 0.49 µg/L in the control group, with a non-significant effect (p = 0.293) between the two groups. The nickel concentration was significantly correlated with patient age (p = 0.005) and reduced handgrip strength (p = 0.003). Regarding biochemical parameters, significant associations were found with the renal glomerular filtration rate (p = 0.024) and blood urea levels (p = 0.016). No significant correlations were observed with other blood analytical parameters or testosterone or estradiol levels. These specific renal function and muscle strength effects were observed at environmental nickel exposure levels believed to be safe or at least far from the high concentrations observed after occupational exposure. Therefore, these parameters deserve further study, given that they could help pinpoint further public health concerns regarding nickel exposure in the general population.

Prenatal exposure to phthalates and its effects upon cognitive and motor functions: A systematic review.

Phthalates are chemicals widely used in packaging and consumer products, which have been shown to interfere with normal hormonal function and development in some human and animal studies. In recent decades, pregnant women's exposure to phthalates has been shown to alter the cognitive outcomes of their babies, and some studies have found delays in motor development. METHODS: electronic databases including PubMed/MEDLINE and Scopus were searched from their inception to March 2021, using the keywords "phthalate", "cognitive" and "motor". RESULTS: most studies find statistically significant inverse relationships between maternal urinary phthalate concentration during pregnancy and subsequent outcomes in children's cognitive and motor scales, especially in boys rather than girls. However, many associations are not significant, and there were even positive associations, especially in the third trimester. CONCLUSION: the relationship between exposure to phthalates during pregnancy and low results on neurocognitive scales is sufficiently clear to adopt policies to reduce exposure. Further studies are needed to analyze sex differences, coordination and motor scales, and phthalate levels during breastfeeding.

Omega-3 Long-Chain Polyunsaturated Fatty Acids Intake in Children: The Role of Family-Related Social Determinants.

Omega-3 long-chain polyunsaturated fatty acids play a central role in neuronal growth and in the development of the human brain, since they are essential elements which depend on intake through diet to ensure an adequate amount. Fish and seafood are the main dietary sources of these fatty acids in Spain and in other countries. In order to assess the effect of the intake of common foods containing high amounts of omega-3 polyunsaturated fatty acids, a food frequency questionnaire was administered to parents of children and adolescents attending a primary school in Valencia (Spain), and the intake of dietary omega-3 such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) was estimated based on their fish/seafood consumption. Low frequencies of intake were significantly (p < 0.05) lower for many types of fish/seafood in children compared to adolescents. 27.5% of children/adolescents did not eat lean fish or other types (19.8% of the sample did not eat fatty fish, and 71.8% did not eat smoked fish) and 20-60% of the sample consumed seafood only once-three times a month, leading to a reduced estimated intake of EPA+DHA below that recommended for both groups by public health agencies. Social aspects, such as the type of work done by mothers and their educational levels are significant factors (p < 0.05 in both cases) affecting children's/adolescents' intake of DHA+EPA. Dietary interventions to increase the consumption of fish and seafood are strongly advised, and health promotion strategies should be aimed at the family level and fight against gender disparities.

Omega-3 Long-Chain Polyunsaturated Fatty Acids Intake in Children with Attention Deficit and Hyperactivity Disorder.

Omega-3 long-chain polyunsaturated fatty acids (LC-PUFA) play a central role in neuronal growth and in the development of the human brain, and a deficiency of these substances has been reported in children with attention deficit hyperactive disorder (ADHD). In this regard, supplementation with omega-3 polyunsaturated fatty acids is used as adjuvant therapy in ADHD. Seafood, particularly fish, and some types of nuts are the main dietary sources of such fatty acids in the Spanish diet. In order to assess the effect of the intake of common foods containing high amounts of omega-3 polyunsaturated fatty acids, a food frequency questionnaire was administered to parents of children with ADHD (N = 48) and to parents of normally developing children (control group) (N = 87), and the intake of dietary omega-3 LC-PUFA, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), was estimated. Children with ADHD consumed fatty fish, lean fish, mollusks, crustaceans, and chicken eggs significantly less often (p < 0.05) than children in the control group. The estimated daily omega-3 LC-PUFA intake (EPA + DHA) was significantly below that recommended by the public health agencies in both groups, and was significantly lower in children with ADHD (p < 0.05, Cohen's d = 0.45) compared to normally developing children. Dietary intervention to increase the consumption of fish and seafood is strongly advised and it is especially warranted in children with ADHD, since it could contribute to improve the symptoms of ADHD.

Quality of Life in People with Coeliac Disease: Psychological and Socio- Economic Aspects.

BACKGROUND AND OBJECTIVE: Coeliac disease (CD) is a chronic autoimmune intestinal disorder characterized by intolerance to gluten, a protein contained in certain cereals. The main physiopathological basis of CD is the progressive destruction of intestinal villi caused by gluten ingestion by genetically-susceptible individuals. Patients who receive a diagnosis of CD must make significant changes to their daily habits and this can affect their quality of life. The objective of this review is to summarize the evidence regarding the economic, physical and social limitations which can affect the quality of life in patients with CD. RESULTS: Different factors such as physical changes, psychological effects, interpersonal relationships, emotions and economic difficulties can affect the quality of life of these patients. Observations suggest that, in general, women with CD experience a greater deterioration in their quality of life than men. Lastly, complications in daily life are also associated with the reduced availability of gluten-free products which also usually cost more than standard products. CONCLUSIONS: Continuous health education and care regarding socio-economic issues should be continuously developed and provided to people with CD.

The effect of probiotics as a treatment for constipation in elderly people: A systematic review.

PURPOSE: Treating constipation in elderly people remains a challenge; the administration of probiotics may be a valid therapy for this problem as an alternative to traditional drug-based treatments. The objective of this systematic review was to evaluate the efficiency of probiotics in treating constipation in elderly people. METHODS: Articles related to this topic and published, without any time limitations, in the Medline, Embase, Scopus, Lilacs, or Cochrane databases were systematically reviewed according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The primary search terms were 'constipation' and 'probiotics'. The main inclusion criteria were: 1) the article was original and the whole text was published in English or Spanish and 2) included the primary search terms in the title, summary, or body text; 3) the studies had to have included 60 or more participants defined as 'elderly' and 4) have specifically evaluated the effect of the administration of probiotics. RESULTS: Of the 475 articles consulted, 9 met the inclusion criteria. Among the selected studies, there were four randomised and placebo-controlled trials and the remaining five reports were observational. Overall, our analysis of the randomised and placebo-controlled trials suggests that administration of probiotics significantly improved constipation in elderly individuals by 10-40% compared to placebo controls in which no probiotic was administered. The strain of bacteria most commonly tested was Bifidobacterium longum. However, caution is needed when interpreting these reports because of the heterogeneity of the original study designs, populations, and the risk of bias. Therefore, further placebo-controlled trials are necessary to determine the most efficient strains, doses, and the optimal treatment duration.

OBJETIVO: Los programas de pago por desempeño para mejorar la calidad de la atención sanitaria se están extendiendo de forma progresiva, en particular para en Atención Primaria. Nuestro objetivo fue explorar la relación entre el grado de cumplimiento de los indicadores de proceso (IPr) de la diabetes mellitus tipo 2 (DM2) en Atención Primaria y la vinculación a incentivos económicos. DISEÑO: Estudio descriptivo observacional, descriptivo y transversal. Emplazamiento: Seis centros de salud del Distrito Aljarafe, Sevilla, seleccionados de forma aleatoria y estratificada por tamaño poblacional. PARTICIPANTES: De un total de 3.647 sujetos incluidos en el Proceso Asistencial Integrado de DM2 durante el 2008, se incluyó a 366 pacientes, según cálculo de tamaño muestral, mediante muestreo aleatorio estratificado. Mediciones: IPr: exploración de fondo de ojo y pies, hemoglobina glucosilada (HbA1c), perfil lipídico, microalbuminuria y electrocardiograma. Variables potencialmente confusoras: edad, género, característica de zona de residencia en pacientes y variables de los médicos. RESULTADOS: La edad media fue de 66,36 (desviación estándar -DE- 11,56 años); el 48,9% eran mujeres. Los IPr con mejor cumplimiento fueron la exploración de pies, HbA1c y perfil lipídico (59,6, 44,3 y 44, respectivamente). El 2,7% de los pacientes presentaban cumplimiento simultáneo de los 6 IPr y el 11,74% de los 3 IPr vinculados a incentivos. El cumplimiento de IPr vinculado y no a incentivos mostró asociación significativa (p = 0,001). CONCLUSIONES: El cumplimiento de los IPr para el cribado de complicaciones crónicas de la DM2 es en su mayoría bajo, aunque este fue superior en los indicadores vinculados a incentivos

Self-reported versus measured height, weight and body mass index in Spanish Mediterranean teenagers: effects of gender, age and weight on perceptual measures of body image.

BACKGROUND: To have a good physical appearance is a determining factor by which adolescents show a tendency to worry excessively about their weight. The aim of this work is to study the possible relationship between actual and perceived body weight, how it is considered and what strategies are followed for weight control among adolescents residing in Valencia. METHODS: A sample of 568 students, 325 girls and 243 boys, aged 14-20 years, were selected from public high schools in Valencia. Their height and weight were used to calculate their actual body mass index (BMIO). The subjective perception of their physical measurements (BMIS) was evaluated by means of a questionnaire. The statistical treatment of data was done with commercially available software. RESULTS: There is a relatively large proportion of underweight subjects among the participants of the survey. Differences between the BMIO and BMIS indicate a misperception of height (overestimated) and weight (underestimated) that is greater in girls than in boys. Girls tend to undergo restrictive dietary measures when they consider themselves overweight. A general lack of knowledge about adequate weight was observed. CONCLUSION: Valencia teenagers show a poor knowledge of their body size and of the weight that should be adequate for their age and tallness.
