Energy utilisation of infants in Southern Brazil

O b j e c t i v e s : To measure the effect of breast-feeding pattern and socio-economic status (SES) on energy intake (EI), total energy expenditure (TEE), minimal observable energy expenditure (MOEE), activity energy expenditure (AEE), anthropometric measures, and the prevalence of obesity. D e s i g n: Synthesis of a secondary analysis of the Pelotas 1993 birth cohort (infants aged 12 months of age), and two community based studies in 4 and 8 month old infants in urban Pelotas, southern Brazil. Infants were categorised into three feeding groups: BM infants, receiving breast milk as the only source of milk; BCFM infants, receiving cows’ milk or formula in addition to breast milk, and (only in the Pelotas 1993 birth cohort) CFM infants, receiving cows’ milk or formula as the only source of milk. Infants were also categorised into two SES groups based on maternal education. M a i n o u t c o m e m e as u r e s : At 8 months TEE was measured using doubly labelled water (2H218O), MOEE by respiration calorimetry. AEE was calculated as the difference between TEE and MOEE. EI was measured by 1-day food weighing (8 mo.) or frequency questionnaire (4 mo.), breast milk intake using the dose to the mother deuterium-oxide (2H2O) turnover method. Weight and length were measured, and body composition calculated from the isotope data. Prevalence of obesity was assessed on the basis of BMI Z-scores. R e s u l ts : At 4 months EI (kcal/kg/d) of BCFM was 18% higher as compared to BM infants (p=0.008), with no differences in anthropometric measures, but at 8 months BCFM infants had a higher fat mass (kg, p=0.016), fat mass index (kg/m2, p=0.013), and MOEE (kcal/kg/d, p=0.041). At 12 months there was no difference in the prevalence of obesity or overweight between BM and BCFM infants. At 8 months TEE (kcal/kg/d) was 21% higher in low as compared to high SES infants (p=0.005). MOEE was not different, and so AEE (kcal/kg/d) was also higher in low SES infants (p=0.022). Overweight or obesity tended to be prevalent more in high SES infants at 8 but not at 12 months. C o n c l u s i o n s : The development of universally applicable values for energy requirements based on data from high SES infants, without reference to feeding pattern, may not be acceptable. Results suggest that high SES infants receiving cows’ milk may be a population group that particularly need attention.
Diversity and antimicrobial activity of endophytic fungi isolated from Securinega suffruticosa in the Yellow River Delta

Securinega suffruticosa (Pall.) Rehd is an excellent natural secondary shrub in the Shell Islands of Yellow River Delta. The roots of S. suffruticosa have high medicinal value and are used to treat diseases, such as neurasthenia and infant malnutrition. Any organism that is isolated from this species is of immense interest due to its potential novel bioactive compounds. In this research, the distribution and diversity of culturable endophytic fungi in S. suffruticosa were studied, and the endophytic fungi with antimicrobial activity were screened. A total of 420 endophytic fungi isolates were obtained from the S. suffruticosa grown in Shell Islands, from which 20 genera and 35 species were identified through morphological and internal transcribed spacer (ITS) sequence analyses. Chaetomium, Fusarium, Cladosporium, and Ceratobasidium were the dominant genera. The high species richness S (42), Margalef index D′ (5.6289), Shannon–Wiener index H′ (3.1000), Simpson diversity index Ds (0.9459), PIE index (0.8670), and evenness Pielou index J (0.8719) and a low dominant index λ (0.0541) indicated the high diversity of endophytic fungi in S. suffruticosa, the various species of endophytic fungi with obvious tissue specificity. The inhibition percentages of the 12 species of such endophytic fungi against Colletotrichum siamense were 3.6%-26.3%. C. globosum, Fusarium sp.3, and C. ramotenellum had a high antibacterial activity against Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. The Minimum Inhibitory Concentration (MIC) and the Minimum Bactericidal Concentration (MBC) were between 0.5 mg/mL and 2 mg/mL. Alkaloid content detection indicated that endophytic fungi had a high alkaloid content, whereas the alkaloid contents of C. globosum and Fusarium sp.3 reached 0.231% and 0.170%, respectively. Members belonging to the endophytic fungal community in the S. suffruticosa of Shell Islands that may be used as antagonists and antibacterial agents for future biotechnology applications were identified for the first time.
Response of Different Treatment Protocols to Treat Chronic Non-Bacterial Osteomyelitis (CNO) of the Mandible in Adult Patients: A Systematic Review

(1) Background: Chronic non-bacterial osteomyelitis (CNO) is an autoinflammatory bone disease of finally unknown etiology, which can occur alone or related with syndromes (chronic recurrent multifocal osteomyelitis—CRMO; synovitis, acne, pustulosis, hyperostosis and osteitis syndrome—SAPHO). The involvement of the mandible is rather rare. (2) Methods: We carried out a systematic literature search on CNO with mandibular involvement, according to the “Preferred Reporting Items for Systematic Reviews and Meta-Analyses” (PRISMA) guidelines, considering the different synonyms for CNO, with a special focus on therapy. (3) Results: Finally, only four studies could be included. A total of 36 patients were treated in these studies—therefore, at most, only tendencies could be identified. The therapy in the included works was inconsistent. Various therapies could alleviate the symptoms of the disease. A complete remission could only rarely be observed and is also to be viewed against the background of the fluctuating character of the disease. The success of one-off interventions is unlikely overall, and the need for long-term therapies seems to be indicated. Non-steroidal anti-inflammatory drugs (NSAIDs) were not part of any effective therapy. Surgical therapy should not be the first choice. (4) Conclusions: In summary, no evidence-based therapy recommendation can be given today. For the future, systematic clinical trials on therapy for CNO are desirable.
The association between adolescent football participation and early adulthood depression

Concerned about potentially increased risk of neurodegenerative disease, several health professionals and policy makers have proposed limiting or banning youth participation in American-style tackle football. Given the large affected population (over 1 million boys play high school football annually), careful estimation of the long-term health effects of playing football is necessary for developing effective public health policy. Unfortunately, existing attempts to estimate these effects tend not to generalize to current participants because they either studied a much older cohort or, more seriously, failed to account for potential confounding. We leverage data from a nationally representative cohort of American men who were in grades 7–12 in the 1994–95 school year to estimate the effect of playing football in adolescent on depression in early adulthood. We control for several potential confounders related to subjects’ health, behavior, educational experience, family background, and family health history through matching and regression adjustment. We found no evidence of even a small harmful effect of football participation on scores on a version of the Center for Epidemiological Studies Depression scale (CES-D) nor did we find evidence of adverse associations with several secondary outcomes including anxiety disorder diagnosis or alcohol dependence in early adulthood. For men who were in grades 7–12 in the 1994–95 school year, participating or intending to participate in school football does not appear to be a major risk factor for early adulthood depression.
Men1 maintains exocrine pancreas homeostasis in response to inflammation and oncogenic stress

Significance Understanding the molecular mechanisms that maintain pancreas homeostasis in response to inflammatory stress is an urgent area of study due to the strong associations between pancreatitis and cancer and diabetes. Through the use of physiologically relevant mouse models, we identify an essential role for Men1 in the normal tissue response to both inflammatory and oncogenic stress. Loss of Men1 induces a proinflammatory gene expression program, associated with deregulation of Jund transcriptional activity. These results provide insights into a regulatory axis that maintains pancreas homeostasis in vivo. A more comprehensive understanding of the molecular mechanisms underlying pancreatic diseases, including pancreatitis and cancer, is essential to improve clinical management. MEN1 has established roles in epigenetic regulation and tumor suppression in the endocrine pancreas; however, intriguing recent data suggest MEN1 may also function in the exocrine pancreas. Using physiologically relevant genetic mouse models, we provide direct evidence that Men1 is essential for exocrine pancreas homeostasis in response to inflammation and oncogenic stress. Men1 loss causes increased injury and impaired regeneration following acute caerulein-induced pancreatitis, leading to more severe damage, loss of the normal acinar compartment, and increased cytokeratin 19-positive metaplasias and immune cell infiltration. We further demonstrate the Men1 protein is stabilized in response to insult, and loss of Men1 is associated with the overexpression of proinflammatory Jund target genes, suggesting that loss of Men1-mediated repression of Jund activity is, at least in part, responsible for the impaired response. Finally, we demonstrate that Men1 loss significantly accelerates mutant Kras-dependent oncogenesis. Combined, this work establishes Men1 as an important mediator of pancreas homeostasis in vivo.
Effects of seasonal and decadal warming on soil enzymatic activity in a P‐deficient Mediterranean shrubland

Soil enzymes are central in the response of terrestrial ecosystems to climate change, and their study can be crucial for the models’ implementation. We investigated for 1 year the effects of warming and seasonality on the potential activities of five soil extracellular enzymes and their relationships with soil moisture, phosphorus (P) concentration, and other soil parameters in a P‐limited Mediterranean semiarid shrubland. The site was continuously subjected to warming since 1999, and we compared data from this study to analogous data from 2004. Warming uniformly increased all enzymes activities, but only when a sufficient amount of soil water was available. Seasonality unevenly altered enzyme activities, thus affecting enzymatic stoichiometry. P deficiency affected enzymatic stoichiometry, favoring the activities of the phosphatases. The effect of warming was stronger in 2014 than 2004, excluding the hypothesis of acclimation of rhizospheric responses to higher temperatures and suggesting that further increases in extracellular enzymatic activities are to be expected if sufficient water is available. Climatic warming will likely generally stimulate soil enzymatic activities and accelerate nutrient mineralization and similar ecological processes such as the production and degradation of biomass and changes in community composition, but which will be limited by water availability, especially in Mediterranean soils in summer. Winters in such ecosystems will benefit from a general increase in activity and production, but biological activity could even decrease in summer, potentially leading to a negative overall balance of nutrient mineralization. This study suggests that a general increase in activity due to warming could lead to faster mineralization of soil organic matter and water consumption in colder climates, until one of these factors in turn becomes limiting. Such trade‐offs between water and temperature in relation with enzyme activity should be considered in biogeochemical models.
In Utero Exposure to Aluminium and Other Neurotoxic Elements in Urban Coastal South African Women at Delivery: An Emerging Concern

Aluminium (Al) is a non-essential neurotoxicant and there is limited information regarding exposure to Al in utero. This study sought to evaluate the in utero exposure to Al in urban South African women, its effects on birth outcomes and possible synergistic effects between Al, essential and neurotoxic elements such as lead (Pb), mercury (Hg) and arsenic (As), as well as a a potential sex-dependent response to these elements in neonates. This study has found elevated levels of Al in urban women at delivery. The Spearman’s rank correlation coefficients (p-value) of the association between maternal serum Al and birth outcomes (gestational age and parity), and between maternal serum Al and Cu, Zn and Se, were statistically significant. However, in the general and the stratified models, no association was found between any of the birth outcomes and maternal serum Al. The association between maternal serum Al and neurotoxic elements at delivery showed a significant positive correlation for Pb only (rho = 0.361; p < 0.001) which was found to be sex-dependent in neonates (males, rho = 0.285; p < 0.004 and females, rho = 0.444, p < 0.001). Our preliminary findings indicate that in utero exposure to Al is an emerging concern requiring further research and directives from public health authorities.
Constitutive modelling of hot deformation behaviour of a CoCrFeMnNi high-entropy alloy

ABSTRACT Models describing the constitutive flow behaviour of a metallic material are desired for appropriate process design and realization of defect-free components. In this study, constitutive equations based on the hyperbolic-sinusoidal Arrhenius-type model have been developed to define the hot deformation characteristics of a CoCrFeMnNi high-entropy alloy. The experimental true stress-true strain data were generated over a wide temperature (1023–1423 K) and strain rates (10−3–10 s−1) ranges. The impact of strain rate and temperature on deformation behaviour was further characterized through a temperature compensated strain rate parameter, i.e. Zener-Hollomon parameter. Additionally, a mathematical relation was employed to express the influence of various material constants on true-strain ranging from 0.2 to 0.75. Typical third order polynomial relations were found to be appropriate to fit the true-strain dependency of these material constants. The accuracy of the developed constitutive equations was evaluated by using the average absolute relative error (AARE) and correlation coefficient (R); the obtained values were 7.63% and 0.9858, respectively, suggesting reasonable predictions. These results demonstrate that the developed constitutive equations can predict the flow stress behaviour of the alloy with a good accuracy over a wide range of temperature and strain rate conditions and for large strains.

Forty Years of the Description of Brown Spider Venom Phospholipases-D

Spiders of the genus Loxosceles, popularly known as Brown spiders, are considered a serious public health issue, especially in regions of hot or temperate climates, such as parts of North and South America. Although the venoms of these arachnids are complex in molecular composition, often containing proteins with distinct biochemical characteristics, the literature has primarily described a family of toxins, the Phospholipases-D (PLDs), which are highly conserved in all Loxosceles species. PLDs trigger most of the major clinical symptoms of loxoscelism i.e., dermonecrosis, thrombocytopenia, hemolysis, and acute renal failure. The key role played by PLDs in the symptomatology of loxoscelism was first described 40 years ago, when researches purified a hemolytic toxin that cleaved sphingomyelin and generated choline, and was referred to as a Sphingomyelinase-D, which was subsequently changed to Phospholipase-D when it was demonstrated that the enzyme also cleaved other cellular phospholipids. In this review, we present the information gleaned over the last 40 years about PLDs from Loxosceles venoms especially with regard to the production and characterization of recombinant isoforms. The history of obtaining these toxins is discussed, as well as their molecular organization and mechanisms of interaction with their substrates. We will address cellular biology aspects of these toxins and how they can be used in the development of drugs to address inflammatory processes and loxoscelism. Present and future aspects of loxoscelism diagnosis will be discussed, as well as their biotechnological applications and actions expected for the future in this field.
Bone Marrow Lymphocyte Populations of Innate Immunity in Breast Cancer Patients

The innate immunity system plays an important role in antitumor protection, and more and more attention has been paid to its study recent years. However, the interrelation of the effect or subpopulations of the cells of the innate immunity in bone marrow with clinical parameters is poorly studied. The paper presents data on the composition of innate immune cells in the bone marrow of 64 patients with operable breast cancer, as well as 10 women with benign processes in the mammary gland. As result a significant correlation between the molecular subtype of cancer and the level of B1lymphocytes was identified. Breast cancer patients levels of NK cells (CD56 + CD3and CD16 + CD3-) in the bone marrow were significantly higher in patients with low proliferative activity (Ki-67 less than 20%), compared to patients having a high tumor proliferation index. Populations of NK cells were interrelated with erythropoiesis in patients with breast cancer and were significantly higher in cases of reduced basophilic and polychromatophilicnormoblasts.
Selective killing of leukemia cells: Yamanaka factors’ new trick

The four transcription factors of the Yamanaka cocktail (Oct4, Sox2, Klf4, and Myc, termed OSKM) are famously capable of reprogramming somatic cells into induced pluripotent stem cells (iPSCs). In an article recently published in Nature Communications, Wang et al describe the unexpected discovery that short‐term activation of OSKM expression in acute myeloid leukemia cells in vivo induces apoptosis while negligibly affecting normal hematopoietic stem and progenitor cells (Nat Commun 2019;10:5594). These findings have potential implications for novel anticancer strategies.
Physical Fitness after Anterior Cruciate Ligament Reconstruction: Influence of Graft, Age, and Sex

Functional tests are used to facilitate return-to-sports decisions after anterior cruciate ligament reconstruction (ACLR). This study presents comprehensive physical fitness test data acquired in highly active patients within the first year after ACLR, for comparison between different grafts, age groups, and sexes. The outcomes from a specific seven-item test battery and isokinetic strength test data were extracted from a patient database. Results were compared to normative data from age- and sex-matched controls and between subgroups of patients. A total of 245 patients (94 women, 23.8 ± 8.4 years, pre-injury Tegner 7.4 ± 1.6) were tested 185 ± 44 days after surgery. In 116 patients (47.3%), one or more test results were classified as “poor” or “very poor” after comparison with normative data, with failures being most frequent during single-leg squat jump and plyometric strength tests. Test failures were more prevalent in adults than in adolescents <19 years (61.4%–62.2% vs. 24.5%, p < 0.001) and in men (61.6% vs. 24.5%, p < 0.001), but no differences were found between grafts. Isokinetic knee extensor strength was lower by 24.1% on the injured side. Six months after ACLR, nearly 50% of highly active patients presented with strength and functional fitness deficits. These deficits are particularly prevalent in older patients and men.
Sex Differences in the Association between Household Chaos and Body Mass Index z-Score in Low-Income Toddlers.

Background: Associations between household chaos and childhood overweight have been identified, but the mechanisms of association are not clearly established in young children, with some studies linking higher chaos to increased obesity risk, whereas other studies link higher chaos to lower obesity risk. Given the lack of consistent findings and early sex differences in vulnerability to chaos, we examined child sex as a moderator of the chaos-child overweight association. We also tested these associations with self-regulation, as self-regulation has been implicated in understanding the chaos-obesity risk association in low-income toddlers. Methods: Parent-reported household chaos and observed child self-regulation were collected at baseline [n = 132; M age 23.0 months (standard deviation 2.8)]. Children's body mass index z-score (BMIz) was measured at 33 months. Multivariate linear regression models were used to assess whether child sex moderated the chaos-BMIz association. A three-way interaction between chaos, child sex, and self-regulation was also tested. Results: Child sex moderated the chaos-BMIz association (b = -0.11, p = 0.04) such that chaos was positively associated with BMIz among boys (b = 0.12, p = 0.003), but unrelated in girls (b = 0.01, p = 0.78). A three-way interaction with self-regulation indicated that a positive chaos-BMIz association existed only for boys with average (b = 0.12, p = 0.004) and low (b = 0.22, p < 0.001) self-regulation. Conclusions: Boys with poor self-regulation may be particularly vulnerable to obesogenic effects of chaotic households.
Comparison of patient perceptions of primary care quality across healthcare facilities in Korea: A cross-sectional study

Primary care is not well established in Korea despite its importance in population health. To reinforce the primary care system, understanding the public view of primary care will be essential. We aimed to compare the public perception of primary care qualities across types of healthcare facilities. We conducted a cross-sectional, web-based survey at a university in Seoul, South Korea, from October 2018 to February 2019. Using the Korean Primary Care Assessment Tool (K-PCAT), participants assessed the qualities of primary care services provided by the university health service (a university-based, patient-centered primary care model), community clinics, and hospitals. We compared K-PCAT scores across facilities and evaluated the factors associated with the differences using general linear models. A total of 5,748 responses were analyzed. K-PCAT total scores were highest for the university health service (61.0 ± 15.9) and lowest for hospitals (48.1 ± 14.5), with significant differences between facilities (P < .001). The university health service received the highest scores for first contact, comprehensiveness, personalized care, and family/community orientation; community clinics for continuity of care; and hospitals for care coordination and trust/satisfaction. Primary care facilities were rated higher than hospitals by individuals in good health, with low income levels, using ambulatory care more frequently, and spending less on medical expenses. In conclusion, the user-perceived primary care quality was higher for community-based primary care facilities than hospitals. The highest score was for the university health service, suggesting that setting-based, patient-centered primary care would be an effective model for restructuring the primary care system in Korea.
