Sarcopenia Does Not Impact the Outcome of Patients with Multiple Myeloma Consolidated with Autologous Hematopoietic Stem Cell Transplantation.

INTRODUCTION: Sarcopenia has been associated with chronic diseases and cancer. The aim of this study was to evaluate sarcopenia in multiple myeloma patients undergoing autologous stem cell transplantation. METHODS: In 68 eligible patients, measurement of skeletal muscle area (cm2) on computed tomography scans at the level of the L3 vertebra (L3 SMI) was performed. RESULTS: 37 (54%) patients were categorized as sarcopenic: 26 males with L3 SMI values <52.4 cm2/m2, and 11 women with L3 SMI values <38.9 cm2/m2. The majority of sarcopenic patients included were older than 60 years (69%, p = 0.0005), with BMI <25 (75%; p = 0.0000). A significant association was found between sarcopenia and Sorror score value >1 (p = 0.02). CONCLUSIONS: The Kaplan-Meier curve showed a median OS of 73.5 months for non-sarcopenic patients versus 86.5 months for sarcopenic patients, suggesting that sarcopenia is not an independent prognostic factor in this cohort of patients. Further prospective studies are needed to confirm these data.

The Use of Mobile Assessments for Monitoring Mental Health in Youth: Umbrella Review.

BACKGROUND: Improving mental health in youth is a major concern. Future approaches to monitor and intervene in youth mental health problems should rely on mobile tools that allow for the daily monitoring of mental health both actively (eg, using ecological momentary assessments [EMAs]) and passively (eg, digital phenotyping) by capturing individuals' data. OBJECTIVE: This umbrella review aims to (1) report the main characteristics of existing reviews on mental health and young people, including mobile approaches to mental health; (2) describe EMAs and trace data and the mental health conditions investigated; (3) report the main results; and (4) outline promises, limitations, and directions for future research. METHODS: A systematic literature search was carried out in 9 scientific databases (Communication & Mass Media Complete, Psychology and Behavioral Sciences Collection, PsycINFO, CINAHL, ERIC, MEDLINE, the ProQuest Sociology Database, Web of Science, and PubMed) on January 30, 2022, coupled with a hand search and updated in July 2022. We included (systematic) reviews of EMAs and trace data in the context of mental health, with a specific focus on young populations, including children, adolescents, and young adults. The quality of the included reviews was evaluated using the AMSTAR (Assessment of Multiple Systematic Reviews) checklist. RESULTS: After the screening process, 30 reviews (published between 2016 and 2022) were included in this umbrella review, of which 21 (70%) were systematic reviews and 9 (30%) were narrative reviews. The included systematic reviews focused on symptoms of depression (5/21, 24%); bipolar disorders, schizophrenia, or psychosis (6/21, 29%); general ill-being (5/21, 24%); cognitive abilities (2/21, 9.5%); well-being (1/21, 5%); personality (1/21, 5%); and suicidal thoughts (1/21, 5%). Of the 21 systematic reviews, 15 (71%) summarized studies that used mobile apps for tracing, 2 (10%) summarized studies that used them for intervention, and 4 (19%) summarized studies that used them for both intervention and tracing. Mobile tools used in the systematic reviews were smartphones only (8/21, 38%), smartphones and wearable devices (6/21, 29%), and smartphones with other tools (7/21, 33%). In total, 29% (6/21) of the systematic reviews focused on EMAs, including ecological momentary interventions; 33% (7/21) focused on trace data; and 38% (8/21) focused on both. Narrative reviews mainly focused on the discussion of issues related to digital phenotyping, existing theoretical frameworks used, new opportunities, and practical examples. CONCLUSIONS: EMAs and trace data in the context of mental health assessments and interventions are promising tools. Opportunities (eg, using mobile approaches in low- and middle-income countries, integration of multimodal data, and improving self-efficacy and self-awareness on mental health) and limitations (eg, absence of theoretical frameworks, difficulty in assessing the reliability and effectiveness of such approaches, and need to appropriately assess the quality of the studies) were further discussed.

Exploring the Interplay between COVID-19 and Gut Health: The Potential Role of Prebiotics and Probiotics in Immune Support.

The COVID-19 pandemic has profoundly impacted global health, leading to extensive research focused on developing strategies to enhance outbreak response and mitigate the disease's severity. In the aftermath of the pandemic, attention has shifted towards understanding and addressing long-term health implications, particularly in individuals experiencing persistent symptoms, known as long COVID. Research into potential interventions to alleviate long COVID symptoms has intensified, with a focus on strategies to support immune function and mitigate inflammation. One area of interest is the gut microbiota, which plays a crucial role in regulating immune responses and maintaining overall health. Prebiotics and probiotics, known for their ability to modulate the gut microbiota, have emerged as potential therapeutic agents in bolstering immune function and reducing inflammation. This review delves into the intricate relationship between long COVID, the gut microbiota, and immune function, with a specific focus on the role of prebiotics and probiotics. We examine the immune response to long COVID, emphasizing the importance of inflammation and immune regulation in the persistence of symptoms. The potential of probiotics in modulating immune responses, including their mechanisms in combating viral infections such as COVID-19, is discussed in detail. Clinical evidence supporting the use of probiotics in managing long COVID symptoms is summarized, highlighting their role as adjunctive therapy in addressing various aspects of SARS-CoV-2 infection and its aftermath.

Do neuroticism and efficacy beliefs moderate the relationship between climate change worry and mental wellbeing?

BACKGROUND: Research on the nature and prevalence of phenomena like climate anxiety (or eco-anxiety) is increasing rapidly but there is little understanding of the conditions under which climate change worry becomes more or less likely to significantly impact mental wellbeing. Here, we considered two plausible moderators of the relationship between climate change worry and mental wellbeing: neuroticism and efficacy beliefs. METHODS: Analysis was conducted with survey data gathered in six European countries in autumn 2019. Participants were recruited from universities in the participating countries using opportunity sampling. RESULTS: We found that climate change worry is negatively related to mental wellbeing at any level of perceived efficacy. In contrast, climate change worry is only significantly related to mental wellbeing at low and average levels of neuroticism. High neuroticism appears to have a masking, rather than amplifying, role in the relationship between climate change worry and mental wellbeing. LIMITATIONS: The cross-sectional design of the study precludes verification of causal relationships among variables. The brief measure of neuroticism employed also did not allow for nuanced analysis of how different facets of neuroticism contribute to the observed interaction with climate change worry. Findings cannot be indiscriminately generalised to less privileged groups facing the worst impacts of the climate crisis. CONCLUSION: Our findings lend to a view that harmful impacts of climate change worry on mental wellbeing cannot simply be ascribed to dispositional traits like neuroticism. We advocate for interventions that tackle negative climate-related emotions as unique psychological stressors.

How socio-institutional contexts and cultural worldviews relate to COVID-19 acceptance rates: A representative study in Italy.

RATIONALE: Despite its importance to counter the COVID-19 pandemic, vaccination has raised hesitation in large segments of the population. This hesitation makes it important to understand the mechanisms underlying vaccine acceptance. To this end, the study adopts the Semiotic Cultural Psychology Theory, holding that social behaviors - and therefore, vaccination acceptance - depend on the cultural meanings in terms of which people interpret the social world. OBJECTIVE: The study aims at estimating the impact a) of the way people interpret the socio-institutional context of the pandemic and b) of the underlying cultural worldviews on vaccine acceptance. More particularly, the study tested the three following hypotheses. a) The meanings grounding the interpretation of the socio-institutional framework - that is, trust in institutions and political values - are an antecedent of vaccination acceptance. b) The impact of these meanings is moderated by the cultural worldviews (operationalized as symbolic universes). And c), the magnitude of the symbolic universes' moderator effect depends on the uncertainty to which the respondent is exposed. The exposure to uncertainty was estimated in terms of socioeconomic status - the lower the status, the high the exposure to uncertainty. METHODS: An Italian representative sample (N = 3020) completed a questionnaire, measuring vaccination acceptance, the meanings attributed to the socio-institutional context - that is, political values and trust in institutions - and symbolic universes. RESULTS: The findings were consistent with the hypotheses. a) Structural equation modelling proved that vaccine acceptance was predicted by trust in institutions. b) Multigroup analysis revealed that symbolic universes moderated the correlation between trust in institutions and vaccine acceptance. And c), the moderation effect of symbolic universes proved to occur only in the segment of lower socio-economic status (i.e., the group exposed to higher uncertainty). CONCLUSIONS: Vaccination acceptance is not only a medical issue; it is also dependent upon the rationalization of the socio-institutional context. Implications for the promotion of vaccination acceptance are discussed.

Safety at high altitude: the importance of emotional dysregulation on pilots' risk attitudes during flight.

Introduction: Aviation psychology is very interested in understanding how personological and psychological variables influence flight performances. Indeed, risk attitudes have been considered as a risk factor for aviation accidents. In this context, emotions and coping style are key variables which could influence concentration by affecting cognition and attention. In addition, the specific training backgrounds seemed to be associated with differences in in-flight accident rates. The aim of the present study was to investigate the association between age, sex, flight experience, emotional dysregulation, coping styles, flight licenses, and pilots' risk attitudes. Methods: Eighty pilots completed an online survey composed of ad hoc questionnaire for sociodemographic and work-related information's and self-report questionnaires that assessed emotional dysregulation, coping styles, and risk attitudes. Results: Results showed that older age and emotional dysregulation were associated with higher risk attitudes in pilots. Moreover, emotional dysregulation seemed to promote worse self-confidence. Ultralight pilots appeared to be more risk-oriented and less self-confident than civil pilots, while more flight experience appeared to favorite greater self-confidence. Discussion: In conclusion, the study suggests the importance of promoting interventions based on sharing pilots' difficulties and emotions and promoting safe attitudes with special attention to ultralight pilots, age, and sex differences.

The Origins of NAFLD: The Potential Implication of Intrauterine Life and Early Postnatal Period.

Fetal life and the first few months after birth represent a plastic age, defined as a "window of opportunity", as the organism is particularly susceptible to environmental pressures and has to adapt to environmental conditions. Several perturbations in pregnancy, such as excessive weight gain, obesity, gestational diabetes mellitus and an inadequate or high-fat diet, have been associated with long-term metabolic consequences in offspring, even without affecting birth weight. Moreover, great interest has also been focused on the relationship between the gut microbiome of early infants and health status in later life. Consistently, in various epidemiological studies, a condition of dysbiosis has been associated with an increased inflammatory response and metabolic alterations in the host, with important consequences on the intestinal and systemic health of the unborn child. This review aims to summarize the current knowledge on the origins of NAFLD, with particular attention to the potential implications of intrauterine life and the early postnatal period. Due to the well-known association between gut microbiota and the risk of NAFLD, a specific focus will be devoted to factors affecting early microbiota formation/composition.

Gut Microbiota and COVID-19: Potential Implications for Disease Severity.

The SARS-CoV-2 pandemic resulted in an unprecedented global crisis. SARS-CoV-2 primarily causes lung infection trough the binding of the virus with the ACE-2 cell receptor located on the surface of the alveolar epithelial cells. Notably, ACE-2 cell receptors are also expressed in the epithelial cells of the intestinal tract (GI). Recent data showed that the microbial communities of the GI might act as local and systematic inflammatory modulators. Gastrointestinal symptoms, including diarrhea, are frequently observed in infected individuals, and recent released data indicate that SARS-CoV-2 may also spread by fecal-oral transmission. Moreover, the gut microbiota's ecosystem can regulate and be regulated by invading pathogens, including viruses, facilitating an effective immune response, which in turn results in less severe diseases. In this regard, increased SARS-CoV-2 mortality and morbidities appear to be frequently observed in elderly immunocompromised patients and in people with essential health problems, such as diabetes, who, indeed, tend to have a less diverse gut microbiota (dysbiosis). Therefore, it is important to understand how the interaction between the gut microbiota and SARS-CoV-2 might shape the intensity of the infection and different clinical outcomes. Here, we provide insights into the current knowledge of dysbiosis during SARS-CoV-2 infection and methods that may be used to re-establish a more correct microbiota composition.

The Role of Gut Bacteriome in Asthma, Chronic Obstructive Pulmonary Disease and Obstructive Sleep Apnoea.

The human body contains a very complex and dynamic ecosystem of bacteria. The bacteriome interacts with the host bi-directionally, and changes in either factor impact the entire system. It has long been known that chronic airway diseases are associated with disturbances in the lung bacteriome. However, less is known about the role of gut bacteriome in the most common respiratory diseases. Here, we aim to summarise the evidence concerning the role of the intestinal bacteriome in the pathogenesis and disease course of bronchial asthma, chronic obstructive pulmonary disease, and obstructive sleep apnea. Furthermore, we discuss the consequences of an altered gut bacteriome on the most common comorbidities of these lung diseases. Lastly, we also reflect on the therapeutic potential of influencing the gut microbiome to improve disease outcomes.

Association between Dietary Habits and Fecal Microbiota Composition in Irritable Bowel Syndrome Patients: A Pilot Study.

Intestinal dysbiosis seems to play a role in the pathophysiology of irritable bowel syndrome (IBS). The present pilot study aimed to elucidate the association between nutrient intake and Mediterranean diet (MD) adherence with IBS symptoms and gut microbiota in IBS patients. The nutrient intake of 28 IBS patients and 21 controls was assessed through a food diary, the reference intake ranges (RIs) for energy-yielding macronutrients and the MD serving score (MDSS) index. MD adherence and nutrients intake were compared to IBS symptoms and fecal microbiota, obtained by 16S rRNA targeted-metagenomics. In IBS patients MDSS index was altered compared to controls (p < 0.01). IBS patients with low-MD score reported severe abdominal pain and higher flatulence point-scales. Through Linear discriminant analysis effect size (LEfSe), Erysipelotrichaceae were detected as a microbial biomarker in IBS patients with altered RIs for macronutrients intake, compared to controls. Lactobacillaceae and Lactobacillus were associated to an altered carbohydrates intake in IBS patients, while specific taxonomic biomarkers, such as Aldercreuzia, Mogibacteriaceae, Rikenellaceae, Parabacteroides and F. prausnitzii were associated with an adequate intake of nutrient in these patients. This study supports an association between dietary patterns and gut microbial biomarkers in IBS patients. Further investigations are needed to clarify these connections.

Mechanisms of Action of Prebiotics and Their Effects on Gastro-Intestinal Disorders in Adults.

In recent years, research has focused on the use of dietary fibers and prebiotics, since many of these polysaccharides can be metabolized by intestinal microbiota, leading to the production of short-chain fatty acids. The metabolites of prebiotic fermentation also show anti-inflammatory and immunomodulatory capabilities, suggesting an interesting role in the treatment of several pathological conditions. Galacto-oligosaccharide and short- and long-chain fructans (Fructo-oligosaccharides and inulin) are the most studied prebiotics, even if other dietary compounds seem to show the same features. There is an increasing interest in dietary strategies to modulate microbiota. The aim of this review is to explore the mechanisms of action of prebiotics and their effects on the principal gastro-intestinal disorders in adults, with a special focus on Galacto-oligosaccharides, Fructo-oligosaccharides, lactulose and new emerging substances which currently have evidence of prebiotics effects, such as xilooligosaccharides, soybean oligosaccharides, isomaltooligosaccharides, lactobionic acid, resistant starch and polyphenols.

Effectiveness of neuromuscular taping on painful hemiplegic shoulder: a randomised clinical trial.

PURPOSE: The purpose of this trial was to investigate changes in pain, the range of motion (ROM) and spasticity in people with painful hemiplegic shoulder (PHS) after the application of an upper limb neuromuscular taping (NMT). METHODS: We conducted a randomised clinical trial. The study included 32 people, 31% female (mean ± SD age: 66 ± 9 years), with PHS after stroke with pain at rest and during functional movements. The experimental group received the application of NMT and a standard physical therapy programme (SPTP), whereas the control group received SPTP. The groups received four 45-minute long sessions over four weeks. The VAS, ROM and spasticity were assessed before and after the intervention with follow-up at four weeks. RESULTS: The experimental group had a greater reduction in pain compared to the control group at the end of the intervention, as well as at one month after the intervention (p < 0.001; all the group differences were greater than 4.5 cm, which is greater than the minimal clinically important difference of 2.0 cm). The experimental group had a significantly higher (i.e. better) ROM, by 30.0°, than the control group in shoulder flexion (95% CI: 37.3-22.7) at 4 weeks and by 24.8° (95% CI: 32.1-17.6) at 8 weeks as well as in abduction by 30.6° (95% CI: 37.5-23.7) at 4 weeks and 25.1° (95% CI: 33.8-16.3) at 8 weeks. CONCLUSION: Our study demonstrates that NMT decreases pain and increases the ROM in subjects with shoulder pain after a stroke. Implications for Rehabilitation Painful hemiplegic shoulder is a frequent complication after stroke with negative impacts on functional activities and on quality of life of people, moreover restricts rehabilitation intervention. Neuromuscular taping is a technique introduced by David Blow for the treatment of neuromuscoloskeletal problems. This study shows the reduction of pain and the improvement of range of motion after the application of an upper limb neuromuscular taping. Rehabilitation professionals who are involved in the management of painful hemiplegic shoulder may like to consider the benefits that neuromuscular taping can produce on upper limb.

Expression of human poly (ADP-ribose) polymerase 1 in Saccharomyces cerevisiae: Effect on survival, homologous recombination and identification of genes involved in intracellular localization.

The poly (ADP-ribose) polymerase 1 (PARP-1) actively participates in a series of functions within the cell that include: mitosis, intracellular signaling, cell cycle regulation, transcription and DNA damage repair. Therefore, inhibition of PARP1 has a great potential for use in cancer therapy. As resistance to PARP inhibitors is starting to be observed in patients, thus the function of PARP-1 needs to be studied in depth in order to find new therapeutic targets. To gain more information on the PARP-1 activity, we expressed PARP-1 in yeast and investigated its effect on cell growth and UV induced homologous recombination. To identify candidate genes affecting PARP-1 activity and cellular localization, we also developed a yeast genome wide genetic screen. We found that PARP-1 strongly inhibited yeast growth, but when yeast was exposed to the PARP-1 inhibitor 6(5-H) phenantridinone (PHE), it recovered from the growth suppression. Moreover, we showed that PARP-1 produced PAR products in yeast and we demonstrated that PARP-1 reduced UV-induced homologous recombination. By genome wide screening, we identified 99 mutants that suppressed PARP-1 growth inhibition. Orthologues of human genes were found for 41 of these yeast genes. We determined whether the PARP-1 protein level was altered in strains which are deleted for the transcription regulator GAL3, the histone H1 gene HHO1, the HUL4 gene, the deubiquitination enzyme gene OTU1, the nuclear pore protein POM152 and the SNT1 that encodes for the Set3C subunit of the histone deacetylase complex. In these strains the PARP-1 level was roughly the same as in the wild type. PARP-1 localized in the nucleus more in the snt1Δ than in the wild type strain; after UV radiation, PARP-1 localized in the nucleus more in hho1 and pom152 deletion strains than in the wild type indicating that these functions may have a role on regulating PARP-1 level and activity in the nucleus.
