The Cultural Fabric of Human Causal Cognition

Causal cognition emerges early in development and confers an important advantage for survival. But does this mean that it is universal in humans? Our cross-disciplinary review suggests a broad evolutionary basis for core components of causal cognition but also underlines the essential role of culturally transmitted content as being uniquely human. The multiple ways in which both content and the key mechanisms of cultural transmission generate cultural diversity suggest that causal cognition in humans is not only colored by their specific cultural background but also shaped more fundamentally by the very fact that humans are a cultural species.
A Prospective Study of Childhood Predictors of Traumatic Brain Injuries Sustained in Adolescence and Adulthood

Objective: Traumatic brain injuries (TBIs) are sustained by approximately 17% of males in the general population, many of whom subsequently present mental disorders, cognitive, and physical problems. Little is known about predictors of TBIs and how to prevent them. The present study aimed to determine whether inattention–hyperactivity and/or all externalizing problems presented by boys at age 10 predict subsequent TBIs to age 34 after taking account of previous TBIs and family social status (FSS). Method: 742 Canadian males were followed, prospectively, from age 6 to 34. Diagnoses of TBIs were extracted from health files, parents-reported sociodemographic and family characteristics at participants’ age 6, and teachers-rated participants’ behaviors at age 10. Separate logistic regression models predicted TBIs sustained from age 11 to 17 and from age 18 to 34. For each age period, two models were computed, one included previous TBIs, inattention–hyperactivity, FSS, and interaction terms, the second included previous TBIs, externalizing problems, FSS, and interaction terms. Results: In models that included inattention–hyperactivity, TBIs sustained from age 11 to 17 were predicted by age 10 inattention–hyperactivity (odds ratio [OR] = 1.46, 1.05 to 2.05) and by TBIs prior to age 11 (OR = 3.50, 1.48 to 8.24); TBIs sustained from age 18 to 34 were predicted by age 10 inattention–hyperactivity (OR = 1.31, 1.01 to 170). In models that included all externalizing problems, TBIs from age 11 to 17 were predicted by prior TBIs (OR = 3.66, 1.51 to 8.39); TBIs sustained from age 18 to 34 were predicted by age 10 externalizing problems (OR = 1.45, 1.12 to 1.86). Neither FSS nor interaction terms predicted TBIs in any of the models. Conclusions: Among males, using evidence-based treatments to reduce inattention–hyperactivity and externalizing problems among boys could, potentially, decrease the risk of TBIs to age 34. Further, boys who sustain TBIs in childhood require monitoring to prevent recurrence in adolescence.
Using Photo Stories to Support Doctor-Patient Communication: Evaluating a Communicative Health Literacy Intervention for Older Adults

Older adults often have limited health literacy and experience difficulties in communicating about their health. In view of the need for efficacious interventions, we compared a narrative photo story booklet regarding doctor-patient communication with a non-narrative but otherwise highly similar brochure. The photo story booklet included seven short picture-based stories about themes related to doctor-patient communication. The non-narrative brochure had comparable pictures and layout and dealt with the same themes, but it did not include any stories. We conducted two Randomized Controlled Trials (RCTs) among older adults with varying levels of health literacy: one RCT in Germany (N = 66) and one RCT in the Netherlands (N = 54); the latter one was followed by an in-depth interview study among a subset of the participants (81.5%; n = 44). In the RCTs, we did not find significant differences between the photo story booklet and the non-narrative brochure. In the interview study, a majority of the participants expressed a preference for the photo story booklet, which was perceived as recognizable, relevant, entertaining and engaging. We conclude that photo story booklets are a promising format but that there is room for improving their effectiveness.
The Antimicrobial and Antiviral Activity of Polyphenols from Almond (Prunus dulcis L.) Skin

Due to their antimicrobial and antiviral activity potential in vitro, polyphenols are gaining a lot of attention from the pharmaceutical and healthcare industries. A novel antiviral and antimicrobial approach could be based on the use of polyphenols obtained from natural sources. Here, we tested the antibacterial and antiviral effect of a mix of polyphenols present in natural almond skin (NS MIX). The antimicrobial potential was evaluated against the standard American Type Culture Collection (ATCC) and clinical strains of Staphylococcus aureus, including methicillin-resistant (MRSA) strains, by minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Herpes simplex virus type I was used for the antiviral assessment of NS MIX by plaque assay. Furthermore, we evaluated the expression of viral cascade antigens. NS MIX exhibited antimicrobial (MIC values of 0.31–1.25 mg/ml) and antiviral activity (decrease in the viral titer ** p < 0.01, and viral DNA accumulation * p < 0.05) against Staphylococcus aureus and HSV-1, respectively. Amongst the isolated compounds, the aglycones epicatechin and catechin showed the greatest activity against S. aureus ATCC 6538P (MIC values of 0.078–0.15 and 0.15 mg/ml, respectively), but were not active against all the other strains. These results could be used to develop novel products for topical use.
Potencial zoonótico de las infecciones por helmintos intestinales en perros callejeros de Ciudad de La Habana

Se determino la prevalencia de infeccion intestinal con helmintos en 461 perros en 2 periodos de tiempo, con la finalidad de evaluar el potencial zoonotico de los perros callejeros en Ciudad de La Habana. Los helmintos identificados fueron: Ancylostoma spp. en 97 animales (21,04 por ciento); Dipylidium caninum en 75 (16,26 por ciento) y Toxocara canis en 91 (19,73 por ciento). Las infecciones con Ancylostoma spp. tuvieron una frecuencia mayor en la estacion de lluvia, mayo-octubre de 2005 (p 1 ano) fueron Ancylostoma spp. y D. caninum. En cuanto al sexo, las perras hembras estaban mas parasitadas por T. canis, mientras que D. caninum fue mas frecuente en los machos. La asociacion parasitaria que mas se observo fue A. caninum y T. canis. Estos resultados permitieron un conocimiento actualizado sobre las principales especies de helmintos que afectan a los perros callejeros y algunas caracteristicas de estas infecciones, que sirve de alerta sobre este potencial zoonotico. The objective of the present study was to evaluate the zoonotic potential of the 461 stray dogs from the City of Havana, as well as, the prevalence of intestinal helminth infection in two periods. The identified helminths were Ancylostoma spp. in 97 dogs (21.04 percent), Dipylidium caninum in 75 (16.26 percent). and Toxocara canis in 91 dos (19.73 percent). Ancylostoma spp. infections were the most frequent in the rainy season,that is, May to October, 2005 (p 1 year) were Ancylostoma spp. and D. caninum. Female dogs were more infected by T. canis, and D. caninum was more frequent in males. The most observed association was A. caninum -T. canis. These results allowed updating knowledge about helminth species affecting stray dogs and some characteristics of these infections, all of which can serve as a warning about this zoonotic potential.
Tea Compounds and the Gut Microbiome: Findings from Trials and Mechanistic Studies

In recent years, the gut microbiome has become a focal point of interest with growing recognition that a well-balanced gut microbiota composition is highly relevant to an individual’s health status and well-being. Its profile can be modulated by a number of dietary factors, although few publications have focused on the effects of what we drink. The present review performed a systematic review of trials and mechanistic studies examining the effects of tea consumption, its associated compounds and their effects on the gut microbiome. Registered articles were searched up to 10th September 2019, in the PubMed and Cochrane library databases along with references of original articles. Human trials were graded using the Jadad scale to assess quality. Altogether 24 publications were included in the main review—six were human trials and 18 mechanistic studies. Of these, the largest body of evidence related to green tea with up to 1000 mL daily (4–5 cups) reported to increase proportions of Bifidobacterium. Mechanistic studies also show promise suggesting that black, oolong, Pu-erh and Fuzhuan teas (microbially fermented ‘dark tea’) can modulate microbial diversity and the ratio of Firmicutes to Bacteroidetes. These findings appear to support the hypothesis that tea ingestion could favourably regulate the profile of the gut microbiome and help to offset dysbiosis triggered by obesity or high-fat diets. Further well-designed human trials are now required to build on provisional findings.
Antibiotic sensitivity and clinical outcomes in staphylococcal scalded skin syndrome

Staphylococcal scalded skin syndrome causes widespread skin denudation primarily in infants < 1 year old. Selection of empiric therapy is complicated by rising rates of antibiotic resistance in community‐acquired staphylococcal infections. Consistent with a previous study, this retrospective review found that SSSS‐associated isolates were more likely to be clindamycin‐resistant and less likely to be methicillin‐resistant compared to overall staphylococcal infections. We favor cephalosporins and penicillinase‐resistant penicillins (eg, oxacillin) for empiric management of SSSS, with consideration of adding MRSA coverage in communities with high MRSA prevalence or failure to improve following several days of treatment.
Ribosome depurination by ricin leads to inhibition of endoplasmic reticulum stress–induced HAC1 mRNA splicing on the ribosome

Ricin undergoes retrograde transport to the endoplasmic reticulum (ER), and ricin toxin A chain (RTA) enters the cytosol from the ER. Previous reports indicated that RTA inhibits activation of the unfolded protein response (UPR) in yeast and in mammalian cells. Both precursor (preRTA) and mature form of RTA (mRTA) inhibited splicing of HAC1u (u for uninduced) mRNA, suggesting that UPR inhibition occurred on the cytosolic face of the ER. Here, we examined the role of ribosome binding and depurination activity on inhibition of the UPR using mRTA mutants. An active-site mutant with very low depurination activity, which bound ribosomes as WT RTA, did not inhibit HAC1u mRNA splicing. A ribosome-binding mutant, which showed reduced binding to ribosomes but retained depurination activity, inhibited HAC1u mRNA splicing. This mutant allowed separation of the UPR inhibition by RTA from cytotoxicity because it reduced the rate of depurination. The ribosome-binding mutant inhibited the UPR without affecting IRE1 oligomerization or cleavage of HAC1u mRNA at the splice site junctions. Inhibition of the UPR correlated with the depurination level, suggesting that ribosomes play a role in splicing of HAC1u mRNA. We show that HAC1u mRNA is associated with ribosomes and does not get processed on depurinated ribosomes, thereby inhibiting the UPR. These results demonstrate that RTA inhibits HAC1u mRNA splicing through its depurination activity on the ribosome without directly affecting IRE1 oligomerization or the splicing reaction and provide evidence that IRE1 recognizes HAC1u mRNA that is associated with ribosomes.
The expression of human leukocyte antigen by human ejaculated spermatozoa

After coitus and insemination, an inflammatory response is evident in the female reproductive tract (FRT). Semen contains a variety of immune‐activating components that have a major role in the induction of an immune response in the FRT. One of the most important is (human leukocyte antigen) HLA molecules which are present in soluble form in seminal plasma and in membrane form on the surface of cells (such as epithelial and leukocytes) existing in semen. Nevertheless, there is considerable debate over the expression of HLA antigens by human spermatozoa. Considering the critical role of HLA molecules in reproduction and the induction of an immune response, it is very important to clearly define HLA expression by spermatozoa and the role of these molecules in sperm morphology, motility, and strength to fertilize an egg. Therefore, the objective of this study was to determine HLA expression by ejaculated spermatozoa. The results of this study will facilitate the design of future studies.
Rumination-focused cognitive behaviour therapy for non-responsive chronic depression: an uncontrolled group study

Abstract Background: One-third of patients with depression do not respond satisfactorily to treatment, and approximately 20% of all patients treated for depression develop a chronic depression. One approach to more effective treatment of chronic and treatment-resistant depression is to target rumination – an underlying mechanism implicated in the development and maintenance of depression. Aim: The purpose of this uncontrolled group study was to investigate the feasibility of individual rumination-focused cognitive behavioural therapy (RfCBT) for patients with chronic and treatment-resistant depression. Method: A total of 10 patients with chronic and treatment-resistant depression were offered 12–16 individual sessions of RfCBT. The primary outcome was depressive symptoms as measured by Hamilton Depression Scale at pre-, post- and 3-month follow-up. Secondary symptoms measured included self-reported rumination and worry. Results: There was a significant reduction in depressive symptoms (p < 0.05), rumination (p < 0.01) and worry (p < 0.5) from pre- to post-treatment. Half of the participants (n = 5) showed significant reliable change on levels of depressive symptoms post-treatment. The reduction in depressive symptoms, rumination and worry were maintained at follow-up. Conclusions: RfCBT was associated with significant reductions in depressive symptoms in a small sample with chronic and treatment-resistant depression. Despite limitations of being a small uncontrolled study with limited follow-up, these results are promising in a difficult to treat population. RfCBT warrants further systematic evaluation.
Impact of Carcinogenic Chromium on the Cellular Response to Proteotoxic Stress

Worldwide, several million workers are employed in the various chromium (Cr) industries. These workers may suffer from a variety of adverse health effects produced by dusts, mists and fumes containing Cr in the hexavalent oxidation state, Cr(VI). Of major importance, occupational exposure to Cr(VI) compounds has been firmly associated with the development of lung cancer. Counterintuitively, Cr(VI) is mostly unreactive towards most biomolecules, including nucleic acids. However, its intracellular reduction produces several species that react extensively with biomolecules. The diversity and chemical versatility of these species add great complexity to the study of the molecular mechanisms underlying Cr(VI) toxicity and carcinogenicity. As a consequence, these mechanisms are still poorly understood, in spite of intensive research efforts. Here, we discuss the impact of Cr(VI) on the stress response—an intricate cellular system against proteotoxic stress which is increasingly viewed as playing a critical role in carcinogenesis. This discussion is preceded by information regarding applications, chemical properties and adverse health effects of Cr(VI). A summary of our current understanding of cancer initiation, promotion and progression is also provided, followed by a brief description of the stress response and its links to cancer and by an overview of potential molecular mechanisms of Cr(VI) carcinogenicity.
Impact of soil fertility management practices on a major insect pest infestation and yield of beans (phaseolus vulgaris L.) in Taita district, Kenya

The common bean is an important food and cash crop in Eastern, Central and Southern Africa. It provides food for more than 100 million people and is a critical source of income for rural households. Common bean yields, however, have declined in the last ten years. This decline is the result of poor soil fertility and nutrient depletion as well as high incidences of insect pests, key among them being the bean stem maggot (BSM). To address soil nutrient depletion and the accompanying declining agricultural productivity, integrated soil fertility management (ISFM) has been adapted as a framework for enhancing crop productivity through combining fertilizer use with other soil fertility management technologies, adapted to local conditions. The current study evaluated the influence of soil fertility treatments on yield and yield components of the common bean. Additionally, to establish the potential links between soil fertility and crop protection, the effect of ISFM interventions on the incidence of the BSM was also assessed. The experiment was carried out in Taita District where agriculture contributes 95% to household income with very little or no fertility inputs in farms. Bean variety Mwezi moja was sown during the wet cropping season. Farm plots were amended with Mavuno fertilizer (a blend of fertilizer containing 11 nutrients); Triple Superphosphate fertilizer with Calcium Ammonium Nitrate (TSP + CAN); cow manure; Trichoderma inoculant; Trichoderma inoculant with cow manure combination; Mavuno fertilizer with Trichoderma inoculants combination; and control (untreated check). Field survey was conducted four weeks after bean emergence to determine the incidence and prevalence of the BSM. Plant survival: dry-seed and and bean straw weight were used as criteria for assessing crop yield. Yield and yield components of common bean were significantly affected by addition of soil ammendments, with Mavuno fertilizer + Trichoderma inoculant improving yield by 52.9%. However, the influence of the soil ammendments on the BSM incidence was minimal. These findings point to the fact that soil fertility management interventions increase crop yield. Nevertheless, to maximise yield, there is a strong need to adopt agroecological strategies that not only optimise soil fertilization but also incorporate a pest management dimension.
Optimizing Hydroxyurea Treatment for Sickle Cell Disease Patients: The Pharmacokinetic Approach

Background: Hydroxyurea (HU) is a FDA- and EMA-approved drug that earned an important place in the treatment of patients with severe sickle cell anemia (SCA) by showing its efficacy in many studies. This medication is still underused due to fears of physicians and families and must be optimized. Methods: We analyzed our population and identified HU pharmacokinetic (PK) parameters in order to adapt treatment in the future. Working with a pediatric population, we searched for the most indicative sampling time to reduce the number of samples needed. Results: Nine children treated by HU for severe SCA were included for this PK study. HU quantification was made using a validated gas chromatography/mass spectrometry (GC/MS) method. Biological parameters (of effectiveness and compliance) and clinical data were collected. None of the nine children reached the therapeutic target defined by Dong et al. as an area under the curve (AUC) = 115 h.mg/L; four patients were suspected to be non-compliant. Only two patients had an HbF over 20%. The 2 h sample was predictive of the medication exposure (r2 = 0.887). Conclusions: It is urgent to be more efficient in the treatment of SCA, and pharmacokinetics can be an important asset in SCA patients.
Myoferlin Regulates Wnt/β-Catenin Signaling-Mediated Skeletal Muscle Development by Stabilizing Dishevelled-2 Against Autophagy

Myoferlin (MyoF), which is a calcium/phospholipid-binding protein expressed in cardiac and muscle tissues, belongs to the ferlin family. While MyoF promotes myoblast differentiation, the underlying mechanisms remain poorly understood. Here, we found that MyoF not only promotes C2C12 myoblast differentiation, but also inhibits muscle atrophy and autophagy. In the present study, we found that myoblasts fail to develop into mature myotubes due to defective differentiation in the absence of MyoF. Meanwhile, MyoF regulates the expression of atrophy-related genes (Atrogin-1 and MuRF1) to rescue muscle atrophy. Furthermore, MyoF interacts with Dishevelled-2 (Dvl-2) to activate canonical Wnt signaling. MyoF facilitates Dvl-2 ubiquitination resistance by reducing LC3-labeled Dvl-2 levels and antagonizing the autophagy system. In conclusion, we found that MyoF plays an important role in myoblast differentiation during skeletal muscle atrophy. At the molecular level, MyoF protects Dvl-2 against autophagy-mediated degradation, thus promoting activation of the Wnt/β-catenin signaling pathway. Together, our findings suggest that MyoF, through stabilizing Dvl-2 and preventing autophagy, regulates Wnt/β-catenin signaling-mediated skeletal muscle development.
Methylglyoxal and Glyoxal as Potential Peripheral Markers for MCI Diagnosis and Their Effects on the Expression of Neurotrophic, Inflammatory and Neurodegenerative Factors in Neurons and in Neuronal Derived-Extracellular Vesicles

Methylglyoxal (MG) and glyoxal (GO) are suggested to be associated with the development of neurodegenerative pathologies. However, their peripheral levels in relation to cognitive decline and their effects on key factors in neuronal cells are poorly investigated. The aim of this study was to determine their serum levels in MCI (mild cognitive impairment) and Alzheimer’s disease (AD) patients, to analyze their effects on the neurotrophic and inflammatory factors, on neurodegenerative markers in neuronal cells and in neuronal derived-extracellular vesicles (nEVs). Our results show that MG and GO levels in serum, determined by HPLC, were higher in MCI. ROC (receiver-operating characteristic curves) analysis showed that the levels of MG in serum have higher sensitivity to differentiate MCI from controls but not from AD. Meanwhile, serum GO levels differentiate MCI from control and AD groups. Cells and nEVs levels of BDNF, PRGN, NSE, APP, MMP-9, ANGPTL-4, LCN2, PTX2, S100B, RAGE, Aβ peptide, pTau T181 and alpha-synuclein were quantified by luminex assay. Treatment of neuronal cells with MG or GO reduced the cellular levels of NSE, PRGN, APP, MMP-9 and ANGPTL-4 and the nEVs levels of BDNF, PRGN and LCN2. Our findings suggest that targeting MG and GO may be a promising therapeutic strategy to prevent or delay the progression of AD.
