The Madonna's body: The social construction of a neutralized body
This paper deals with the statue of Our Lady of Maidens, kept in the parish church of Civitella Roveto in the Abruzzo region, in Italy. After describing the religious rituals involving the statue of this Virgin in order to shed light on her title, the study goes on to analize vernacular discourses about her and explore the prohibition regarding the touching of her body. The symbolic aspects of the shapeless body of the statue are then investigated and discussed in the light of Marian, anthropological, sociological, and feminist literature, considering them a specific device for expelling female sexual desire from the domain of fertility. The article, focused on the body of the Madonna, hopes to contribute to studies in religious materiality as well as to studies in the social construction of gender inequality
Quality of life in Parkinsonâs disease: Italian validation of the Parkinsonâs Disease Questionnaire (PDQ-39-IT)
Translation and cross-cultural adaptation of the 39-item Parkinsonâs Disease Questionnaire (PDQ-39) to the Italian culture was performed by Oxford University Innovation in 2008, but this version has never been validated. Therefore, we performed the process of validation of the Italian version of the PDQ-39 (PDQ-39-IT) following the âConsensus-Based Standards for the Selection of Health Status Measurement Instrumentsâ checklist. The translated PDQ-39-IT was tested with 104 patients diagnosed with Parkinsonâs disease (PD) who were recruited between June and October 2017. The mean age of the participants was 65.7 ± 10.2 years, and the mean duration of symptoms was 7.4 ± 5.3 years. The internal consistency of the PDQ-39-IT was assessed by Cronbachâs alpha and ranged from 0.69 to 0.92. In an assessment of test-retest reliability in 35 of the 104 patients, the infraclass correlation coefficient (ICC) ranged from 0.85 to 0.96 for the various subitems of the PDQ-39-IT (all p < 0.01). Spearmanâs rank correlation coefficient for the validity of the PDQ-39-IT and the Italian version of the 36-Item Short Form (SF-36) was â 0.50 (p < 0.01). The results show that the PDQ-39-IT is a reliable and valid tool to assess the impact of PD on functioning and well-being. Thus, the PDQ-39-IT can be used in clinical and research practice to assess this construct and to evaluate the overall effect of different treatments in Italian PD patients
Reliability and validity of the geriatric depression scale in Italian subjects with Parkinson's disease
Introduction. The Geriatric Depression Scale (GDS) is commonly used to assess depressive symptoms, but its psychometric properties have never been examined in Italian people with Parkinson's disease (PD). The aim of this study was to study the reliability and validity of the Italian version of the GDS in a sample of PD patients. Methods. The GDS was administered to 74 patients with PD in order to study its internal consistency, test-retest reliability, construct, and discriminant validity. Results. The internal consistency of GDS was excellent (α = 0.903), as well as the test-retest reliability (ICC = 0.941 [95% CI: 0.886-0.970]). GDS showed a strong correlation with instruments related to the depression (Ï = 0.880) in PD (Ï = 0.712) and a weak correlation with generic measurement instruments (-0.320 < Ï <-0.217). An area under the curve of 0.892 (95% CI 0.809-0.975) indicated a moderate capability to discriminate depressed patients to nondepressed patient, with a cutoff value between 15 and 16 points that predicts depression (sensitivity = 87%; specificity = 82%). Conclusion. The GDS is a reliable and valid tool in a sample of Italian PD subjects; this scale can be used in clinical and research contexts
Exploring clade differentiation of the Faecalibacterium prausnitzii complex
Faecalibacterium prausnitzii is one of the most prevalent and abundant polyphyletic health18 promoting components of the human gut microbiome with a propensity for dysbiotic decreases. To better understand its biology in the human gut, we specifically explored the divergence pressures acting on F. prausnitzii clades on a global scale. Five F. prausnitzii clades were de novo identified from 55 publicly available genomes and 92 high-quality metagenome assembled genomes. Divergence rate indices were constructed and validated to compare the divergence rates among the different clades and between each of the diverging genes. For each clade we identified specific patterns of diverging functionalities, probably reflecting different ecological propensities, in term of inter-host dispersion capacity or exploitation of different substrates in the gut environment. Finally, we speculate that these differences may explain, at least in part, the observed differences in the overall divergence rates of F. prausnitzii clades in human populations
Connect the dots: sketching out microbiome interactions through networking approaches
Microbiome networking analysis has emerged as a powerful tool for studying the complex interactions among microorganisms in various ecological niches, including the human body and several environments. This analysis has been used extensively in both human and environmental studies, revealing key taxa and functional units peculiar to the ecosystem considered. In particular, it has been mainly used to investigate the effects of environmental stressors, such as pollution, climate change or therapies, on host-associated microbial communities and ecosystem function. In this review, we discuss the latest advances in microbiome networking analysis, including methods for constructing and analyzing microbiome networks, and provide a case study on how to use these tools. These analyses typically involve constructing a network that represents interactions among microbial taxa or functional units, such as genes or metabolic pathways. Such networks can be based on a variety of data sources, including 16S rRNA sequencing, metagenomic sequencing, and metabolomics data. Once constructed, these networks can be analyzed to identify key nodes or modules important for the stability and function of the microbiome. By providing insights into essential ecological features of microbial communities, microbiome networking analysis has the potential to transform our understanding of the microbial world and its impact on human health and the environment
Tools to assess the quality of life in patients with Parkinsonâs disease. A systematic review
Introduction
. The clinical, social, and economic implications of Parkinsonâs disease (PD) are significant; disability occurs leading to a low quality of life (QoL). Information on the QoL of patients with PD and studies on the relationship between QoL and motor and cognitive function are necessary for both research and clinical use to make informed decisions in healthcare and rehabilitation. The aim of this study was to determine which scales are most used to assess QoL in patients with PD.
Area covered
. A literature search was conducted in MEDLINE, Scopus, CINAHL, PsycINFO, and Web of Science. Two authors independently identified eligible studies based on predefined inclusion criteria and extracted the data. Study quality and the risk of bias were assessed using the COSMIN checklist.
Expert opinion
. 116 suitable studies were included, and 42 different instruments were identified. The most frequently used scales were the 39-items and 8-items Parkinsonâs Disease Questionnaire (PDQ-39) (PDQ-8). These findings suggest further investigation of existing PD outcome measures would benefit patients, researchers, and clinicians. Validated, universal outcome measures are required to allow comparisons across practice; therefore, we recommend that future researchers use a common set of outcome assessments based on the results of this review
Microbiota-gut-brain axis and ketogenic diet: how close are we to tackling epilepsy?
The microbiota-gut-brain axis refers to the intricate bidirectional communication between commensal
microorganisms residing in the digestive tract and the central nervous system, along neuroendocrine, metabolic,
immune, and inflammatory pathways. This axis has been suggested to play a role in several neurological disorders,
such as Parkinsonâs disease, Alzheimerâs disease, multiple sclerosis, and epilepsy, paving the way for microbiomebased intervention strategies for the mitigation and treatment of symptoms. Epilepsy is a multifaceted neurological
condition affecting more than 50 million individuals worldwide, 30% of whom do not respond to conventional
pharmacological therapies. Among the first-hand microbiota modulation strategies, nutritional interventions
represent an easily applicable option in both clinical and home settings. In this narrative review, we summarize the
mechanisms underlying the microbiota-gut-brain axis involvement in epilepsy, discuss the impact of antiepileptic
drugs on the gut microbiome, and then the impact of a particular dietary pattern, the ketogenic diet, on the
microbiota-gut-brain axis in epileptic patients. The investigation of the microbiota response to nonpharmacological therapies is an ever-expanding field with the potential to allow the design of increasingly
accessible and successful intervention strategies
The gut microbiome of Baka forager-horticulturalists from Cameroon is optimized for wild plant foods
The human gut microbiome is losing biodiversity, due to the "microbiome modernization process" that occurs with urbanization. To keep track of it, here we applied shotgun metagenomics to the gut micro- biome of the Baka, a group of forager-horticulturalists from Cameroon, who combine hunting and gathering with growing a few crops and working for neighboring Bantu-speaking farmers. We analyzed the gut microbiome of individuals with different access to and use of wild plant and processed foods, to explore the variation of their gut microbiome along the cline from hunter-gatherer to agricultural subsis- tence patterns. We found that 26 species-level genome bins from our cohort were pivotal for the degra- dation of the wild plant food substrates. These microbes include Old Friend species and are encoded for genes that are no longer present in industrialized gut microbiome. Our results highlight the potential relevance of these genes to human biology and health, in relation to lifestyle
Microbiome network in the pelagic and benthic offshore systems of the northern Adriatic Sea (Mediterranean Sea)
Because of their recognized global importance, there is now the urgent need to map diversity and distribution patterns of marine microbial communities. Even if available studies provided some advances in the understanding the biogeographical patterns of marine microbiomes at the global scale, their degree of plasticity at the local scale it is still underexplored, and functional implications still need to be dissected. In this scenario here we provide a synoptical study on the microbiomes of the water column and surface sediments from 19 sites in a 130 km2 area located 13.5 km afar from the coast in the North-Western Adriatic Sea (Italy), providing the finest-scale mapping of marine microbiomes in the Mediterranean Sea. Pelagic and benthic microbiomes in the study area showed sector specific-patterns and distinct assemblage structures, corresponding to specific variations in the microbiome network structure. While maintaining a balanced structure in terms of potential ecosystem services (e.g., hydrocarbon degradation and nutrient cycling), sector-specific patterns of over-abundant modules-and taxa-were defined, with the South sector (the closest to the coast) characterized by microbial groups of terrestrial origins, both in the pelagic and the benthic realms. By the granular assessment of the marine microbiome changes at the local scale, we have been able to describe, to our knowledge at the first time, the integration of terrestrial microorganisms in the marine microbiome networks, as a possible natural process characterizing eutrophic coastal area. This raises the question about the biological threshold for terrestrial microorganisms to be admitted in the marine microbiome networks, without altering the ecological balance
Validity and reliability of the 12-item Berg Balance Scale in an italian population with Parkinsonâs disease: a cross sectional study
Background: The Berg Balance Scale is widely used to measure balance ability in clinical practice. Recently, the original version was
redefined from 14 into 12 items. Its psychometric properties were investigated for different populations. However, for Parkinson disease
the new version has not been validated yet. Objective: The purpose of the present study was to evaluate psychometric properties of the
12-item Berg Balance Scale (BBS-12) in a population with Parkinson disease. Methods: Internal consistency was evaluated with Cronbachâs alpha coefficient, whereas reliability was assessed with the intraclass correlation coefficient. For validity analysis, the Pearson correlation coefficient of the BBS-12 was evaluated with the Tinetti Scale and the Physical Activity Scale for the Elderly. Results: The BBS-12 was applied to 50 individuals with a mean age of 65.6 years (SD 11.8). The internal consistency showed a good value (Cronbachâs alpha 0.886) and reproducibility reveled very high performances for both inter-rater and intra-rater reliabilities (ICC 0.987 and 0.986, respectively). The validity study demonstrated good linear correlation with the Tinetti Scale (p<0.01) and with the Sport and Home Subscales of the Physical Activity Scale for the Elderly (p<0.01). Conclusions: The present findings revealed the BBS-12 as a reliable and valid assessment tool to measure balance ability in Parkinson disease. Italian health professionals can now use it with more confidence
