Impaired Conscious Recognition of Negative Facial Expressions in Patients with Locked-in Syndrome
The involvement of facial mimicry in different aspects of human emotional processing is widely debated. However, little is known about
relationships between voluntary activation of facial musculature and conscious recognition of facial expressions. To address this issue,
we assessed severely motor-disabled patients with complete paralysis of voluntary facial movements due to lesions of the ventral pons
[locked-in syndrome (LIS)]. Patients were required to recognize othersâ facial expressions and to rate their own emotional responses to
presentation of affective scenes.LISpatientswere selectivelyimpairedin recognition of negativefacial expressions,thusdemonstratingthatthe
voluntary activation of mimicry represents a high-level simulation mechanism crucially involved in explicit attribution of emotions
Post-traumatic stress disorder (PTSD) in parents of children with type 1 diabetes during Covid-19 pandemic
Introduction The Post-traumatic Stress Disorder (PTSD) is a group of persistent psychological and physiological symptoms due to a traumatic, severe, event. Only few studies focused on the effects of Covid-19 on psychosocial outcomes in children with Type 1 Diabetes (T1D) and their parents. Aim of the study The aim of this study was to evaluate the presence PTSD in parents of children with T1D during COVID-19 pandemic lockdown. Patients and methods In the period between March and May 2020 we submitted the "Impact of Event Scale - Revised" (IES-R) questionnaire to the parents of 34 children with Type 1 Diabetes, asking them to express their emotions about the ongoing Covid-19 pandemic. Results A total of thirty mothers (mean age 43.0 +/- 4.2 years) and 25 fathers (mean age 45.6 +/- 5.9 years) participated in the survey and completed the questionnaires. 29.1% of parents had a score that allows to define a clinically relevant level of PTSD; ten mothers and 6 fathers had a PTSD clinically relevant score, corresponding, respectively, to 28.4 and 24% of total mothers and fathers. Finally, mothers and fathers, both express PTSD symptoms mainly in the form of intrusion and hyperarousal. Conclusions The present study confirms a high prevalence symptoms related to PTSD in mothers and fathers of children with Type 1 Diabetes. We believe that psychosocial outcomes of the COVID-19 pandemic should be taken into account in the planning of the next future assistance for children with T1D
Preliminary data related to the effect of climacostol produced by the freshwater ciliate climacostomum virens on human adenovirus
The new epidemiological scenario has so far focused on the environmental circulation of human viral pathogens. Owing to the side effects of chemical disinfectants, there is an increasing need for knowledge on the use of virucidal compounds, especially those of a natural origin. Climacostol is a molecule produced by a freshwater ciliate and it exhibits activity against bacterial and fungal pathogens. We thus also speculated that there might be an effect on viral viability, which has never been tested. To evaluate such activity, we chose human adenovirus (HAdV), which is representative of waterborne viruses. We conducted experiments using HAdV serotype 5, whose titer was determined by infecting HeLa cell cultures. HAdV5 was shown to be sensitive to climacostol at a concentration of 0.0002 mg/mL, with an approximate 3 Log10 reduction when the initial titer of HAdV5 was approximately 104 and 103 TCID50/mL. These preliminary results could be an important starting point for further research aimed at improving the characterization of climacostol activity under different experimental conditions and against various viruses, including enveloped ones (i.e., the coronavirus). The production of climacostol by a protist living in fresh water also suggests a possible application in the activated sludge of wastewater treatment plants
Suicidal behaviours among adolescents from 90 countries: A pooled analysis of the global school-based student health survey
Background: Understanding the burden and determinants of suicide during adolescence is key to achieving global health goals. We examined the prevalence and determinants of self-reported suicidal ideation and attempts among younger (13-15 years) and older adolescents (16-17 years).Methods: Pooled prevalence estimates with 95% confidence interval, were calculated for suicide ideation and attempts for 118 surveys from 90 countries that administered the Global School-based Student Health Survey (GSHS) to adolescents (13-17 years of age) from 2003 to 2017. Indicators (including individual and social factors) associated with suicidal ideation and attempts were determined from multivariable linear regressions on key outcomes.Results: The prevalence of suicidal ideation representing 397,299 adolescents (51.3% female) was significantly higher among girls than boys whereas attempts did not differ by age or sex. Being bullied, or having no close friends was associated with suicidal ideation among girls 13-15 years and 16-17 years, respectively. Among all boys, being in a fight and having no close friends was associated with suicidal ideation with the addition of serious injury for boys 13-15 years. Common to all younger adolescents was an association of suicide attempt with being bullied and having had a serious injury. Among young boys, having no close friends was an additional indicator for suicide attempt. Having no close friends was associated with suicide attempt in older adolescents with the addition to being bullied in older girls and serious injury in older boys.Conclusions: Building positive social relationships with peers and avoiding serious injury appear key to suicide prevention strategies for vulnerable adolescents. Targeted programs by age group and sex for such indicators could improve mental health during adolescence in low and middle-income countries, given the diverse risk profiles for suicidal ideation and attempts
Global occurrence of Torque teno virus in water systems
Bacterial indicator organisms are used globally to assess the microbiological safety of waters. However, waterborne viral outbreaks have occurred in drinking water systems despite negative bacterial results. Using viral markers may therefore provide more accurate health risk assessment data. In this study, fecal, wastewater, stormwater, surface water (fresh and salt), groundwater, and drinking water samples were analyzed for the presence or concentration of traditional indicators, innovative indicators and viral markers. Samples were obtained in the United States, Italy, and Australia and results compared to those reported for studies conducted in Asia and South America as well. Indicators included total coliforms, Escherichia coli, enterococci, male-specific coliphages, somatic coliphages and microviradae. Viral markers included adenovirus, polyomavirus, and a potential new surrogate, Torque teno virus (TTV). TTV was more frequently found in wastewaters (38-100%) and waters influenced by waste discharges (25%) than in surface waters used as drinking water sources (5%). TTV was also specific to human rather than animal feces. While TTV numbers were strongly correlated to other viral markers in wastewaters, suggesting its utility as a fecal contamination marker, data limitations and TTV presence in treated drinking waters demonstrates that additional research is needed on this potential viral indicator
Meropenem vs standard of care for treatment of neonatal late onset sepsis (NeoMero1): A randomised controlled trial.
BACKGROUND: The early use of broad-spectrum antibiotics remains the cornerstone for the treatment of neonatal late onset sepsis (LOS). However, which antibiotics should be used is still debatable, as relevant studies were conducted more than 20 years ago, recruited in single centres or countries, evaluated antibiotics not in clinical use anymore and had variable inclusion/exclusion criteria and outcome measures. Moreover, antibiotic-resistant bacteria have become a major problem in many countries worldwide. We hypothesized that efficacy of meropenem as a broad-spectrum antibiotic is superior to standard of care regimens (SOC) in empiric treatment of LOS and aimed to compare meropenem to SOC in infants aged 44 weeks meeting the Goldstein criteria of sepsis, were randomized in a 1:1 ratio to receive meropenem or one of the two SOC regimens (ampicillin+gentamicin or cefotaxime+gentamicin) chosen by each site prior to the start of the study for 8-14 days. The primary outcome was treatment success (survival, no modification of allocated therapy, resolution/improvement of clinical and laboratory markers, no need of additional antibiotics and presumed/confirmed eradication of pathogens) at test-of-cure visit (TOC) in full analysis set. Stool samples were tested at baseline and Day 28 for meropenem-resistant Gram-negative organisms (CRGNO). The primary analysis was performed in all randomised patients and in patients with culture confirmed LOS. Proportions of participants with successful outcome were compared by using a logistic regression model adjusted for the stratification factors. From September 3, 2012 to November 30th 2014, total of 136 patients (instead of planned 275) in each arm were randomized; 140 (52%) were culture positive. Successful outcome at TOC was achieved in 44/136 (32%) in the meropenem arm vs. 31/135 (23%) in the SOC arm (p = 0.087). The respective numbers in patients with positive cultures were 17/63 (27%) vs. 10/77 (13%) (p = 0.022). The main reason of failure was modification of allocated therapy. Treatment emergent adverse events occurred in 72% and serious adverse events in 17% of patients, the Day 28 mortality was 6%. Cumulative acquisition of CRGNO by Day 28 occurred in 4% of patients in the meropenem and 12% in the SOC arm (p = 0.052). CONCLUSIONS: Within this study population, we found no evidence that meropenem was superior to SOC in terms of success at TOC, short term hearing disturbances, safety or mortality were similar in both treatment arms but the study was underpowered to detect the planned effect. Meropenem treatment did not select for colonization with CRGNOs. We suggest that meropenem as broad-spectrum antibiotic should be reserved for neonates who are more likely to have Gram-negative LOS, especially in NICUs where microorganisms producing extended spectrum- and AmpC type beta-lactamases are circulating

Rising to the challenge: Producing and sustaining a nutrient-dense and climate-resilient food basket for all
Rapidly destabilizing climatic and other biophysical conditions, competition for natural resources, geopolitical conflicts, and market pressures will continue to impose constraints and shocks to the food system, the greatest impacts of which will be felt by nutritionally vulnerable populations. Creating a just, nutritious, and sustainable food system that feeds the world requires a paradigm shift on where, what, and how we grow food while ensuring equitable channels of distribution. Moving forward, we must generate new science, reorient policies, and invest in a suite of environmental, technological, and sociocultural transformations from farm to fork
Food safety considerations in relation to Anisakis pegreffii in anchovies (Engraulis encrasicolus) and sardines (Sardina pilchardus) fished off the Ligurian Coast (Cinque Terre National Park, NW Mediterranean)
Aims: The purpose of this work was to verify whether E. coli is a good indicator of viral contamination in mussels and Adenovirus could represent a better alternative as indicator organism of viral presence to guarantee consumer health protection.
Methods and Results: Eighty samples of mussels from La Spezia Gulf were analysed for E. coli, Salmonella, Adenovirus, Norovirus and hepatitis A virus with cultural and biomolecular tests. The results of bacterial parameters showed E. coli within the lawâs limits and the absence of Salmonella. Twelve samples were positive for Adenovirus presence, one for Norovirus genogroup II and two for hepatitis A virus. None of these positive mussels was found to be contaminated with more than one virus at the same time.
Conclusion: This study showed that there was not a direct correlation between the presence of human pathogenic viruses and bacterial indicators.
Significance and Impact of the Study: Both E. coli and Adenovirus cannot be considered valid substitutes for the direct research of human pathogenic viruses in mussels. To improve consumer health protection, the European Commission will provide standardized methods for Norovirus and hepatitis A virus detection as soon as possible

Challenges and opportunities for increasing the effectiveness of food reformulation and fortification to improve dietary and nutrition outcomes
Reformulation, a change to a food or beverageâs processing or composition, can reduce potentially harmful ingredients such as salt, added sugar, and saturated and trans fats or increase potentially beneficial ingredients or nutrients such as fiber, protein, and micronutrients. Poor nutrition and health outcomes of populations have stimulated programs and policies to reduce the intake of salt, added sugar, and unhealthy fats and increase healthy nutrients and ingredients to meet recommended targets of a healthy diet. Alongside promoting the consumption of whole, nutritious foods (e.g., fruits, vegetables, and whole grains), reformulation, including fortification of processed foods, has been utilized by food industry manufacturers to contribute to improving diets and aligning with national dietary guidelines. This paper summarizes a literature review and twenty semistructured interviews with experts on food product reformulation and fortification to highlight the challenges, limitations, and opportunities for increasing their effectiveness. While studies have shown that reformulation could have beneficial public health impacts, such as iodized salt, there are a dearth of rigorous evaluations, particularly for some types of reformulations. Importantly, some evidence suggests that ultra-processing has significant adverse health effects independently of nutrient adequacy. To improve population health, reformu lation should be complemented with a range of approaches, including food taxes and subsidies, public food procurement, restrictions on food advertising and marketing, front-of-pack labeling, and changes to food envi ronments that improve availability, affordability, and demand for whole and minimally processed foods
