Salivary IL-1ß, IL-6, and IL-10 Are Key Biomarkers of Periodontitis Severity.

To explore severity and progression biomarkers, we examined the clinical relevance of multiple cytokines and mediators involved in the inflammatory response in periodontitis. A cohort of 68 patients was enrolled in the study and periodontal status assessed by the current classification of periodontal diseases. Immune mediators present in saliva, of both patients and healthy controls, were quantified using a Legendplex-13 panel. Clinic parameters were significantly higher in PD patients compared with HC, with a strong significant association with the disease severity (stage) (p < 0.001), but not with progression (grade). The panel of immune mediators evidenced elevated levels of pro-inflammatory cytokines IL-6 and IL-1ß as disease established (p < 0.01). IL-1ß/IL-1RA ratio was increased in PD patients, being associated with disease stage. An anti-inflammatory response was spotted by higher IL-10. Lower levels of IL-23 and IP-10 were associated with disease severity. No significant statistical differences were found by grade classification. Moreover, salivary IL-1ß and IL-6 exhibited significant positive correlations with several clinical measurements (PI, BOP, PPD, CAL), while IP-10 showed a statistical negative correlation with BOP, PPD, and CAL. These insights highlight the complexity of the periodontitis inflammatory network and the potential of cytokines as biomarkers for refined diagnostic and therapeutic strategies.

Multicriteria Measures to Assess the Sustainability of Diets: A Systematic Review.

CONTEXT: Assessing the overall sustainability of a diet is a challenging undertaking requiring a holistic approach capable of addressing the multicriteria nature of this concept. OBJECTIVE: The aim was to identify and summarize the multicriteria measures used to assess the sustainability characteristics of diets reported at the individual level by healthy adults. DATA SOURCES: Articles were identified via PubMed, Scopus, and Web of Science. The search strategy consisted of key words and MeSH terms, and was concluded in September 2022, covering references in English, Spanish, and Portuguese. DATA EXTRACTION: This systematic review followed the PRISMA guidelines. The search identified 5663 references, from which 1794 were duplicates. Two reviewers independently screened the titles and abstracts of each of the 3869 records and the full-text of the 144 references selected. Of these, 7 studies met the inclusion criteria. DATA ANALYSIS: A total of 6 multicriteria measures were identified: 3 different Sustainable Diet Indices, the Quality Environmental Costs of Diet, the Quality Financial Costs of Diet, and the Environmental Impact of Diet. All of these incorporated a health/nutrition dimension, while the environmental and economic dimensions were the second and the third most integrated, respectively. A sociocultural sustainability dimension was included in only 1 of the measures. CONCLUSION: Despite some methodological concerns in the development and validation process of the identified measures, their inclusion is considered indispensable in assessing the transition towards sustainable diets in future studies. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42022358824.

Sleep duration is associated with appetitive traits in school-age years - results from the Generation XXI birth cohort.

Sleep may influence appetite regulation through physiological and neurocognitive pathways. However, the association between sleep and appetite in childhood has been scarcely reported, particularly using a prospective design. We aimed to test associations between sleep duration at 7 years of age (y) and appetitive traits at both 7 and 10 y. Participants are from the population-based birth cohort Generation XXI (Porto, Portugal), at 7 (n = 2437) and 10 y (n = 1938) follow-ups. Data on sleep was gathered at 7 y and, considering bedtime and get-up time, total mean sleep duration was calculated and further categorized according to the 10th and 90th percentiles. Appetitive traits were assessed at 7 and 10 y using the parent-reported Children's Eating Behaviour Questionnaire. Associations were tested through Generalized Linear Models (co-variates: child's sex; maternal age, education and pre-pregnancy body mass index at 7 y). At 10 y, associations were further adjusted for the respective appetitive trait at 7 y. Children slept a mean of 10.2 h/night, and 13% and 9% slept ≤9.5 and ≥ 11.0 h/night at 7 y, respectively. For each additional hour in sleep duration, children scored 0.078 (99%CI: -0.145; -0.011) lower on Food Responsiveness, 0.065 (99%CI: -0.129; -0.002) lower on Emotional Undereating and 0.096 (99%CI: -0.161; -0.032) lower on Food Fussiness. Lastly, children sleeping ≤9.5 h/night scored higher on Food Responsiveness (ß = 0.145 99%CI: 0.020; 0.271); while those sleeping ≥11.0 h/night scored lower on Food Fussiness (ß = -0.255 99%CI: -0.370; -0.079). No significant prospective associations were found. In conclusion, in 7 y children, sleep duration was cross-sectionally associated with lower scores on food approach (Food Responsiveness) and avoidant traits (Emotional Undereating and Food Fussiness). However, the magnitude of the associations was small and further studies are warranted.

Metal and metalloid maternal transfer in a newborn West Indian manatee (Trichechus manatus) two years after the northeastern oil spill disaster of 2019 in Brazil.

A large-scale oil spill along the northeastern Brazilian coast in 2019-2020 severely impacted primary manatee habitats in Brazil. This study aimed to assess metal and metalloid contamination in a dead manatee calf found following this oil spill. Several elements were detected, including chromium, iron, nickel, lead, and vanadium, which are crude oil components, and thallium, a component of dispersants used to degrade and dissipate crude oil. The presence of these contaminants in the manatee calf is indicative of maternal exposure, metabolism, and newborn transference via placenta and lactation. This is the first report of mother-calf metal transfer in manatees, highlighting the species' vulnerability and potential long-term population dynamics effects, and the first report for several metals and metalloids in these animals, laying the foundation for future research efforts. These findings highlight the urgent need for continued environmental monitoring, ecotoxicological assessments, and conservation initiatives.

Appetitive traits from childhood to adolescence: Analysis of their stability, derivation of trajectory profiles, and associated characteristics.

This study aimed to assess the potential stability of appetitive traits from childhood to early adolescence, identify groups of individuals with distinct trajectories for these traits, and explore their association with other child and family characteristics. Participants were 5040 children from the Generation XXI cohort. Appetitive traits were assessed with the Children's Eating Behaviour Questionnaire (CEBQ) at ages seven, 10, and 13 (eight subscales). Mixed-effect models estimated individual trajectories of appetitive traits and Gaussian mixture models identified groups following different trajectories (appetitive trait trajectory profiles). Appetitive traits showed moderate-to-high stability across the three ages (intra-class correlation coefficients:0.66-0.83); most of the variance observed across time were due to persistent individual differences rather than age-related changes. Six appetitive trait trajectory profiles were identified: 'Moderate appetite' (scores close to the average) (29% of children), 'Small to moderate appetite' (lowest food approach and emotional eating) (26%), 'Increasing appetite' (increasing food approach) (15%), 'Avid appetite' (highest food approach and lowest food avoidance) (12%), 'Smallest appetite' (highest food avoidance and low food approach) (10%), and 'Small appetite but increasing' (decreasing high food avoidance and Desire to Drink) (8%). In multinomial logistic regression, these profiles were associated with different child and family characteristics. Compared to children with a 'Moderate appetite' profile, those with higher BMI, who desired a thinner body, whose mothers were younger, had lower education, higher pre-pregnancy BMI (OR = 1.07; 95%CI:1.04,1.09), smoked during pregnancy (OR = 1.51; 95%CI:1.21,1.90), and used more restrictive feeding practices (OR = 1.79; 95%CI:1.57,2.03) had increased odds of belonging to the 'Avid Appetite'. In conclusion, distinct appetitive trait trajectory profiles emerged, differentiating individuals with avid and small appetites. These findings have implications for identifying children at higher risk for obesogenic profiles.

Vehicle-assisted ligature decapitation - an unusual case report.

Suicide by vehicle-assisted strangulation resulting in decapitation is a rare occurrence, characterized by a high kinetic energy mechanism that produces a clean-cut appearance in the decapitation area. Often resembling an incisive wound, this particular finding can mislead local authorities into investigating the case as a homicide. This case report describes an adult male who accelerated his vehicle after tying a nylon rope around his neck and securing it to a metallic structure on the wall. Furthermore, we conducted a brief review of cases published within the last ten years, summarizing the most prevalent findings associated with these incidents. By analyzing previously reported cases alongside our own, we aim to consolidate the prevailing patterns observed in vehicle-assisted strangulation cases. This underscores the paramount importance of thorough scene analysis by the medico-legal team and emphasizes the significance of subsequent necropsy findings in accurately discerning the manner of death.

Generation of glucocorticoid-producing cells derived from human pluripotent stem cells.

Adrenal insufficiency is a life-threatening condition resulting from the inability to produce adrenal hormones in a dose- and time-dependent manner. Establishing a cell-based therapy would provide a physiologically responsive approach for the treatment of this condition. We report the generation of large numbers of human-induced steroidogenic cells (hiSCs) from human pluripotent stem cells (hPSCs). Directed differentiation of hPSCs into hiSCs recapitulates the initial stages of human adrenal development. Following expression of steroidogenic factor 1, activation of protein kinase A signaling drives a steroidogenic gene expression profile most comparable to human fetal adrenal cells, and leads to dynamic secretion of steroid hormones, in vitro. Moreover, expression of the adrenocorticotrophic hormone (ACTH) receptor/co-receptor (MC2R/MRAP) results in dose-dependent ACTH responsiveness. This protocol recapitulates adrenal insufficiency resulting from loss-of-function mutations in AAAS, which cause the enigmatic triple A syndrome. Our differentiation protocol generates sufficient numbers of hiSCs for cell-based therapy and offers a platform to study disorders causing adrenal insufficiency.

How Deep Can the Endophytic Mycobiome Go? A Case Study on Six Woody Species from the Brazilian Cerrado.

Elucidating the complex relationship between plants and endophytic fungi is very important in order to understand the maintenance of biodiversity, equity, stability, and ecosystem functioning. However, knowledge about the diversity of endophytic fungi from species of the native Brazilian Cerrado biome is poorly documented and remains largely unknown. These gaps led us to characterize the diversity of Cerrado endophytic foliar fungi associated with six woody species (Caryocar brasiliense, Dalbergia miscolobium, Leptolobium dasycarpum, Qualea parviflora, Ouratea hexasperma, and Styrax ferrugineus). Additionally, we investigated the influence of host plant identities on the structure of fungal communities. Culture-dependent methods coupled with DNA metabarcoding were employed. Irrespective of the approach, the phylum Ascomycota and the classes Dothideomycetes and Sordariomycetes were dominant. Using the cultivation-dependent method, 114 isolates were recovered from all the host species and classified into more than 20 genera and 50 species. Over 50 of the isolates belonged to the genus Diaporthe, and were distributed into more than 20 species. Metabarcoding revealed the phyla Chytridiomycota, Glomeromycota, Monoblepharomycota, Mortierellomycota, Olpidiomycota, Rozellomycota, and Zoopagomycota. These groups are reported for the first time as components of the endophytic mycobiome of Cerrado plant species. In total, 400 genera were found in all host species. A unique leaf endophytic mycobiome was identified in each host species, which differed not only by the distribution of fungal species, but also by the abundance of shared species. These findings highlight the importance of the Brazilian Cerrado as a reservoir of microbial species, and emphasize how endophytic fungal communities are diversified and adapted.

Parental child-feeding practices at 4 years of age are associated with dietary patterns of 7-year-olds.

BACKGROUND: Parental child-feeding practices have been associated with child body mass index (BMI) and specific food group consumption; however, their role in the development of dietary patterns is less understood. We aim to study the association between parental child-feeding practices at 4 years old and dietary patterns at 7 years that explain BMI z-scores at age 10. METHODS: Participants were children from the Generation XXI birth cohort (n = 3272). Three patterns of feeding practices at 4 years were previously identified: 'Perceived monitoring', 'Restriction' and 'Pressure to eat'. At 7 years, two dietary patterns were derived: 'Energy-dense foods', higher consumption of energy-dense foods and drinks and processed meats and lower consumption of vegetable soup (significantly associated with BMI z-scores at 10 years) and 'Fish-based', higher in fishery intake and lower in energy-dense food intake. Associations were estimated by linear regression models, adjusted for potential confounders (mother's age, education and pre-pregnancy BMI). RESULTS: Girls whose parents used more Restriction, Perceived monitoring and Pressure to eat at 4 years were less likely to follow the 'Energy-dense foods' dietary pattern at 7 years (ß̂ = -0.082; 95% confidence intervals [CI]: -0.134; -0.029; ß̂ = -0.093; 95% CI: -0.146; -0.039; ß̂ = -0.079; 95% CI: -0.135; -0.04, respectively). In both sexes, children whose parents used more Restriction and Perceived monitoring at 4 years were more likely to follow the 'Fish-based' dietary pattern at 7 years (girls: ß̂ = 0.143; 95% CI: 0.077; 0.210; ß̂ = 0.079; 95% CI: 0.011; 0.148; boys: ß̂ = 0.157; 95% CI: 0.090; 0.224; ß̂ = 0.104; 95% CI: 0.041; 0.168). CONCLUSIONS: Children whose parents used more Restriction and Perceived monitoring at preschool age were more likely to follow healthier dietary patterns at age 7.

Analysis of Salivary Levels of IL-1ß, IL17A, OPG and RANK-L in Periodontitis Using the 2017 Classification of Periodontal Diseases-An Exploratory Observational Study.

Periodontitis is a chronic disease with a high overall prevalence. It involves a complex interplay between the immune-inflammatory pathways and biofilm changes, leading to periodontal attachment loss. The aims of this study were (i) to assess whether the salivary IL-1ß, IL-17A, RANK-L and OPG levels have the potential to discriminate between the mild and severe periodontitis conditions; and (ii) to enable diagnostic/prognostic actions to differentiate between distinct levels of the disease. The analysis of the clinical parameters and the evaluation of the salivary immunomediators levels by means of a multiplex flow assay revealed a statistically significantly higher level of IL-1ß in the periodontitis III/IV patients, as well as a higher level of RANK-L in the periodontitis III/IV and I/II patients, when compared to the healthy controls. Furthermore, the grade C periodontitis patients presented a significantly higher level of RANK-L compared to the grade B and grade A patients. In the grade C patients, IL-1ß had a positive correlation with the PPD and CAL indices and RANK_L had a positive correlation with CAL. The evidence emerging from this study associates the salivary IL-1ß and RANK-L levels with an advanced stage of periodontitis, stage III/IV, and with grade C, suggesting the possible cooperative action of both in the inflammatory and bone loss events. In addition to IL-1ß, RANK-L could be considered a combined diagnostic biomarker for periodontitis.

Mental Health of Healthcare Professionals: Two Years of the COVID-19 Pandemic in Portugal.

The COVID-19 pandemic increased psychosocial risk factors among healthcare professionals (HCPs). Objective: To characterize Portuguese HCPs mental health (MH), estimate anxiety, depression, post-traumatic stress disorder (PTSD) and burnout symptoms, and identify risk/protective factors. A cross-sectional online survey and a longitudinal assessment were conducted in 2020 (T0) and 2021 (T1). Sociodemographic and occupational variables, COVID-19-related experiences and protective behavior data were collected from a non-probabilistic sample of HCPs in Portugal. Symptoms of anxiety, depression, PTSD, burnout and resilience were assessed using the Portuguese versions of the Generalized Anxiety Disorder Scale (GAD-7), the Patient Health Questionnaire (PHQ-9), the Post-traumatic Stress Disorder Checklist (PCL-5), the Shirom-Melamed Burnout Measure (MBSM) and the Connor-Davidson Resilience Scale (CD-RISC-10), respectively. Risk and protective factors were identified through simple and multiple logistic regression models. Overall, 2027 participants answered the survey in T0 and 1843 in T1. The percentage of moderate-to-severe symptoms decreased from T0 to T1; however, a considerable proportion of HCPs reported symptoms of distress in both years. Being a woman, working in a COVID-19-treatment frontline position and work-life balance increased the odds of distress. High resilience, good social/family support, and hobbies/lifestyle maintenance were found to be protective factors. Globally, our results show that performing as a HCP during the pandemic may result in long-term effects on MH.

Parental Feeding Practices and Children's Eating Behaviours: An Overview of Their Complex Relationship.

Several studies have found an association between eating behaviours and weight status and obesity risk in childhood. Children's eating behaviours arise from a combination of genetic and environmental factors. Parents appear to play a central role in their development as the main responsible for shaping children's feeding environment and eating experiences. The purpose of this paper is to review the literature on parental influences on eating behaviours across childhood, mainly focusing on parental feeding practices. The associations between parental feeding practices and children's eating behaviours have been extensively studied. However, most of the findings come from cross-sectional studies, so the possibility of reverse causality cannot be ruled out (i.e., children's behaviours influencing parents). Most recently, a few longitudinal studies with a cross-lagged design have shown that the relationship between children's eating behaviours and parental feeding practices seems to be bidirectional, where it is not straightforward whether parental feeding practices are a predictor or a consequence of children's eating behaviours. Children's eating behaviours influence parents to adopt certain feeding practices, but these practices also influence children's behaviours over time. Parental feeding practices may have the potential to shape children's eating behaviours and should be targeted to promote the development of non-obesogenic traits. However, parent-child interactions are complex and therefore both parent and child characteristics and the family dynamics should be considered.

Early life exposures are associated with appetitive traits in infancy: findings from the BiTwin cohort.

PURPOSE: To determine the stability of appetitive traits during infancy and their association with early life exposures. METHODS: Participants were from the BiTwin birth cohort (longitudinal study of Portuguese infants). Appetitive traits at 3 months were measured using the Baby Eating Behaviour Questionnaire (n = 347) and at 12 months with the Children's Eating Behaviour Questionnaire for toddlers (n = 325). Stability was assessed with multi-level models. The association of early life exposures (weight for gestational age, mode of feeding, prematurity, smoking during pregnancy, maternal pre-pregnancy BMI, gestational weight gain, and diabetes mellitus diagnosis) with infant appetitive traits was estimated by multivariable linear regression models. RESULTS: Appetite traits showed limited stability (ICCs: 0.25-0.34). Associations with early life exposures varied by age. At 3 months, infants of mothers with higher pre-pregnancy BMI and excessive gestational weight gain had low Satiety Responsiveness. In contrast, infants small for gestational age scored high in this trait (ß̂ = 0.241; 95% CI 0.056-0.425). Exclusively formula-fed infants presented weak food approach traits at this age, namely low Enjoyment of Food (ß̂ = - 0.145; 95% CI - 0.270 to - 0.019) and Food Responsiveness (ß̂ = - 0.415; 95% CI - 0.618 to - 0.212). At 12 months, infants who were small for gestational age had low Food Responsiveness (ß̂ = - 0.297; 95% CI - 0.523 to - 0.072), in contrast, infants of mothers who gained excessive gestational weight had high scores in this trait. Formula feeding was related to rapid eating (Slowness in Eating: ß̂ = - 0.252; 95% CI 0.451 to - 0.054). CONCLUSION: Early life exposures may play a role in the development of infants' appetitive traits, which then change during the first year of life. Interventions focussed on maternal and infant health may have the potential to shape appetite in infancy.

Characterizing the Inflammatory Microenvironment in K14-HPV16 Transgenic Mice: Mast Cell Infiltration and MicroRNA Expression.

High-risk human papillomavirus (HPV) is the etiologic agent of several types of cancer. Mast cells' role as either a driving or opposing force for cancer progression remains controversial. MicroRNAs are dysregulated in several HPV-induced cancers, and can influence mast cell biology. The aim of this study was to evaluate mast cell infiltration and to identify microRNAs potentially regulating this process. Transgenic male mice (K14-HPV16; HPV+) and matched wild-type mice (HPV−) received 7,12-Dimethylbenz[a]anthracene (DMBA) (or vehicle) over 17 weeks. Following euthanasia, chest skin and ear tissue samples were collected. Mast cell infiltration was evaluated by immunohistochemistry. MicroRNAs associated with mast cell infiltration were identified using bioinformatic tools. MicroRNA and mRNA relative expression was evaluated by RT-qPCR. Immunohistochemistry showed increased mast cell infiltration in HPV+ mice (p < 0.001). DMBA did not have any statistically significant influence on this distribution. Ear tissue of HPV+ mice showed increased mast cell infiltration (p < 0.01) when compared with chest skin samples. Additionally, reduced relative expression of miR-125b-5p (p = 0.008, 2−ΔΔCt = 2.09) and miR-223-3p (p = 0.013, 2−ΔΔCt = 4.42) seems to be associated with mast cell infiltration and increased expression of target gene Cxcl10. These results indicate that HPV16 may increase mast cell infiltration by down-regulating miR-223-3p and miR-125b-5p.

Karyotypical Confirmation of Natural Hybridization between Two Manatee Species, Trichechus manatus and Trichechus inunguis.

Two species of manatees are found in Northern Brazil-the Antillean manatee (Trichechus manatus), which is found along the coast from Florida to Northeastern Brazil, and the Amazonian manatee (Trichechus inunguis), endemic to the Amazon drainage basin. These species show a sympatric distribution in the region of the Marajó Archipelago, an estuarine area surrounding the Amazon River mouth. There is evidence of the occurrence of interspecific hybrids in this area, based on mitochondrial DNA analyses, although the use of nuclear markers has not corroborated this proposal. Considering that these species show very distinct karyotypes, despite being closely related (2n = 48 in T. manatus and 2n = 56 in T. inunguis), hybrids would present distinct chromosome numbers. Based on this, we conducted cytogenetic analyses using classic and molecular techniques in three calves found stranded in the Marajó Island and Amapá coast. The results showed that one of them, morphologically classified as T. inunguis, presented the correspondent karyotype, with 2n = 56. However, the other two, which were phenotypically similar to T. manatus, showed 2n = 49. Despite the same diploid number, their G-banding patterns revealed some differences. The results of the distribution of some microsatellite sequences have also confirmed the heterozygosity of some chromosomal pairs in these two individuals. These results are the first indubitable confirmation of the occurrence of natural hybrids between T. manatus and T. inunguis, and also brings about some issues concerning the viability of hybrids, considering that these two individuals do not correspond to an F1 hybrid, but instead, both presented a possible F2 karyotype.

Validity of the Adult Eating Behavior Questionnaire and Its Relationship with Parent-Reported Eating Behaviors among Adolescents in Portugal.

The Adult Eating Behavior Questionnaire (AEBQ) is a tool developed in the UK, used in the investigation of appetitive traits in adults and adolescents, and later validated in a number of countries. To date, the validity of the AEBQ has not been tested on Portuguese-speaking popula-tions. The aim of this study was to validate the AEBQ in a sample of Portuguese adolescents. Participants were 4483 13-year-olds enrolled in the population-based cohort study Generation XXI. Appetitive traits were self-reported by adolescents through the AEBQ and parents also reported adolescent eating behaviors. Confirmatory and exploratory factor analyses were conducted. Construct validity was tested through correlations between AEBQ subscales and parent-reported eating behaviors, and linear regressions between AEBQ subscales and adolescent body mass index z-scores were performed. Adequate internal consistency and several associations with parent-reported eating behaviors and measured adolescent body mass index z-scores were found. This study supports the validity of a five-factor AEBQ (Food Responsiveness and Enjoyment of Food; Slowness in Eating; Food Fussiness; Emotional Over- and Undereating) to measure appetitive traits among Portuguese adolescents and provides a convenient and easy-to-use tool to be used in large-scale research.

Association of early feeding practices with dietary patterns of 7-year-olds from the birth cohort Generation XXI.

Early feeding practices have been related to child's body mass index (BMI), however, their role in establishing dietary patterns is less well understood. The aim of this study was to examine the association of parent-reported early feeding practices (breastfeeding duration, type of foods and timing of complementary feeding) and dietary patterns identified at age 7 to explain BMI z-scores at 10 years of age. Participants were children from the Generation XXI cohort, evaluated at 4, 7 and 10 years of age (n = 3673). At 7 years-old, dietary intake was assessed with a validated food-frequency questionnaire. Two dietary patterns were previously derived: "Energy-dense foods" (higher in energy-dense foods, and lower in vegetable soup, significantly associated with BMI z-score at 10 years-old, and the "Fish-based" dietary pattern (higher in fish consumption and low in energy-dense foods). Adjusted sex-stratified associations were estimated by generalized linear models. Boys and girls who were never breastfed or were breastfed for a very short duration had lower scores in the "Fish-based" dietary pattern, compared to those with longer breastfeeding durations (Boys: ß = -0.219; 95%CI: 0.361; -0.077; Girls: ß = -0.223; 95%CI: 0.358; -0.088). No significant associations between breastfeeding and the "Energy-dense foods" dietary pattern were found. Boys and girls who were offered cereals as a first food during complementary feeding, in comparison with soup, presented lower scores in the "Energy-dense foods" dietary pattern (Boys: ß = -0.183; 95%CI: 0.292; -0.074; Girls: ß = -0.155; 95%CI: 0.259; -0.050), but only girls presented higher scores in the 'Fish-based' dietary pattern (ß = 0.137; 95%CI: 0.006; 0.267). The age of introduction of complementary feeding was not significantly associated with the dietary patterns. Parents should be supported in their infant feeding decisions, given the potential effects of breastfeeding duration and first foods at complementary feeding on shaping longer term dietary patterns of young children.

Maternal perception, concern and dissatisfaction with child weight and their association with feeding practices in the Generation XXI birth cohort.

What a mother thinks about her child's weight status might influence what and how she feeds her child. We examined the association between maternal perception, concern and dissatisfaction with child weight alongside feeding practices. Participants were from the Generation XXI birth cohort (n = 3233). A validated version of the Child Feeding Questionnaire and the Overt/Covert Control scale were used. Associations were evaluated by linear regression models (ß coefficients and 95 % confidence intervals (95 % CI) with Bonferroni correction). Perceived underweight was associated with practices promoting food intake, such as higher pressure to eat at ages 4 and 7 years (ß = 0·229; 95 % CI: 0·059, 0·398 and ß = 0·190; 95 % CI:0·005, 0·376, respectively) and lower restriction at age 4 (ß = -0·175; 95 % CI: -0·0310, -0·039). At age 7, perceived overweight was associated with higher covert control (ß = 0·203; 95 % CI: 0·029, 0·376). Mothers who were concerned about child weight reported higher restriction (ß = 0·226; 95 % CI: 0·142, 0·310 at 4 years and ß = 0·261; 95 % CI: 0·169, 0·353 at 7 years) and covert control (ß = 0·183; 95 % CI: 0·083, 0·282 at 4 years and ß = 0·171; 95 % CI: 0·073, 0·269 at 7 years). Maternal desire for a heavier child was associated with higher pressure to eat at both ages (ß = 0·285; 95 % CI: 0·163, 0·406 and ß = 0·393; 95 % CI: 0·266, 0·520), while the desire for a thinner child was related to higher covert control at 7 years of age (ß = 0·158; 95 % CI: 0·001, 0·316). Maternal perceptions and concern for child weight status are associated with feeding practices independently of actual weight status.

Towards Drug Repurposing in Cancer Cachexia: Potential Targets and Candidates.

As a multifactorial and multiorgan syndrome, cancer cachexia is associated with decreased tolerance to antitumor treatments and increased morbidity and mortality rates. The current approaches for the treatment of this syndrome are not always effective and well established. Drug repurposing or repositioning consists of the investigation of pharmacological components that are already available or in clinical trials for certain diseases and explores if they can be used for new indications. Its advantages comparing to de novo drugs development are the reduced amount of time spent and costs. In this paper, we selected drugs already available or in clinical trials for non-cachexia indications and that are related to the pathways and molecular components involved in the different phenotypes of cancer cachexia syndrome. Thus, we introduce known drugs as possible candidates for drug repurposing in the treatment of cancer-induced cachexia.

Impact of immune cells on the hallmarks of cancer: A literature review.

Tumor-infiltrating immune cells (TIICs) are critical players in the tumor microenvironment, modulating cancer cell functions. TIICs are highly heterogenic and plastic and may either suppress cancers or provide support for tumor growth. A wide range of studies have shed light on how tumor-associated macrophages, dendritic cells, neutrophils, mast cells, natural killer cells and lymphocytes contribute for the establishment of several hallmarks of cancer and became the basis for successful immunotherapies. Many of those TIICs play pivotal roles in several hallmarks of cancer. This review contributes to elucidate the multifaceted roles of immune cells in cancer development, highlighting molecular components that constitute promising therapeutic targets. Additional studies are needed to clarify the relation between TIICs and hallmarks such as enabling replicative immortality, evading growth suppressors, sustaining proliferative signaling, resisting cell death and genome instability and mutation, to further explore their therapeutic potential and improve the outcomes of cancer patients.
