Background and Aims Interactions between different yeast species used as starters may lead to inconsistent results in mixed fermentations. The aim of this study was to assess the influence of different nutrients on the association between a wine strain of C andida zemplinina ( CDZ1) and a commercial wine strain of S accharomyces cerevisiae ( EC1118) in mixed culture fermentations. Methods and Results Laboratory-scale fermentations were carried out by inoculating CDZ1 and, after 3 days, EC1118 with the simultaneous addition of diammonium phosphate, yeast hulls, ergosterol and oleic acid, each provided separately. The addition of yeast hulls resulted in a higher cell population of CDZ1 and in a higher glycerol concentration of wine as compared with that of the other fermentations. Pilot-scale fermentations, carried out in a commercial winery, confirmed that the winemaking protocol based on the use of the mixed starters CDZ1/ EC1118 with added yeast hulls results in wine with a higher glycerol content, more structured and persistent. Conclusions Addition of yeast hulls improved the fermentative performance of the mixed starters CDZ1/ EC1118. Significance of the Study The high glycerol content of wines made with the combined use of yeast hulls and CDZ1/ EC1118 mixed starters increases wine softness and body. [ABSTRACT FROM AUTHOR]

In developmental studies, inferring regulatory interactions of segmentation genetic network play a vital role in unveiling the mechanism of pattern formation. As such, there exists an opportune demand for theoretical developments and new mathematical models which can result in a more accurate illustration of this genetic network. Accordingly, this paper seeks to extract the meaningful regulatory role of the maternal effect genes using a variety of causality detection techniques and to explore whether these methods can suggest a new analytical view to the gene regulatory networks. We evaluate the use of three different powerful and widely-used models representing time and frequency domain Granger causality and convergent cross mapping technique with the results being thoroughly evaluated for statistical significance. Our findings show that the regulatory role of maternal effect genes is detectable in different time classes and thereby the method is applicable to infer the possible regulatory interactions present among the other genes of this network.

The maternal segmentation coordinate gene bicoid plays a significant role during Drosophila embryogenesis. The gradient of Bicoid, the protein encoded by this gene, determines most aspects of head and thorax development. This paper seeks to explore the applicability of a variety of signal processing techniques at extracting bicoid expression signal, and whether these methods can outperform the current model. We evaluate the use of six different powerful and widely-used models representing both parametric and nonparametric signal processing techniques to determine the most efficient method for signal extraction in bicoid. The results are evaluated using both real and simulated data. Our findings show that the Singular Spectrum Analysis technique proposed in this paper outperforms the synthesis diffusion degradation model for filtering the noisy protein profile of bicoid whilst the exponential smoothing technique was found to be the next best alternative followed by the autoregressive integrated moving average.

Over the recent decade cognitive diagnostic measurement approach in spite of the prevalent (common) educational measurement approaches such as classic theory and item-response theory has attained a special status, because this approach integrates cognition theories with learning so as to provide a profile of students’ cognitive competencies. With regard to such approach, a diagnostic test concerning students’ math literacy cognitive competencies consisting of 20 questions based on cognitive model of PISA (2012) was devised. The test included Communication & Using symbolic, formal and technical language and operations; Mathematising & Representation; Reasoning & Argument and Devising strategies for solving problems. The statistical population of the present research consisted of 10th grade students in the field of mathematics, science and literature, during the academic year of 1392-1393. Through Probability Proportional to Size approach, a sample of 688 students was selected and the test was administered. Students’ responses were analyzed by using DINA model and R software. Diagnostic capacity of test at the item level and producing students’ competency profiles were reported. The research findings indicated that through a diagnostic test based on cognitive competencies and by using DINA model, students’ competency profile could be identified.

Drosophila melanogaster ,segmentation ,signal extraction ,singular spectrum analysis ,Medicine - Abstract
Drosophila segmentation as a model organism is one of the most highly studied. Among many maternal segmentation coordinate genes, bicoid protein pattern plays a significant role during Drosophila embryogenesis, since this gradient determines most aspects of head and thorax development. Despite the fact that several models have been proposed to describe the bicoid gradient, due to its association with considerable error, each can only partially explain bicoid characteristics. In this paper, a modified version of singular spectrum analysis is examined for filtering and extracting the bicoid gene expression signal. The results with strong evidence indicate that the proposed technique is able to remove noise more effectively and can be considered as a promising method for filtering gene expression measurements for other applications.

- Abstract
The clinical and neurophysiologic data from 65 patients taking thalidomide were reviewed. Thalidomide sensory neurotoxicity was found to be cumulative dose dependent but occurs only when the total dose is relatively high (>20 g). The risk of developing sensory neuropathy is around 10 below this threshold but increases with higher doses.

- Abstract
The authors prospectively followed 14 patients treated with thalidomide for cutaneous lupus erythematosus (CLE), in order to evaluate the occurrence of peripheral neuropathy (PN) and to assess whether PN correlates with thalidomide dose. The patients were followed for up to 24 months with neurologic and electrophysiologic evaluations. Seven patients (50) developed sensory axonal PN. The median time free from PN was 14 months. PN occurred after 10 months in the majority of patients. No correlations were found between thalidomide cumulative dose and occurrence of PN (Mann-Whitney U test; p> 0.16).

Genetics ,QH426-470 - Abstract
Approximately 80% of human breast carcinomas present as oestrogen receptor α-positive (ER+ve) disease, and ER status is a critical factor in treatment decision-making. Recently, single nucleotide polymorphisms (SNPs) in the region immediately upstream of the ER gene (ESR1) on 6q25.1 have been associated with breast cancer risk. Our investigation of factors associated with the level of expression of ESR1 in ER+ve tumours has revealed unexpected associations between genes in this region and ESR1 expression that are important to consider in studies of the genetic causes of breast cancer risk. RNA from tumour biopsies taken from 104 postmenopausal women before and after 2 weeks treatment with an aromatase (oestrogen synthase) inhibitor was analyzed on Illumina 48K microarrays. Multiple-testing corrected Spearman correlation revealed that three previously uncharacterized open reading frames (ORFs) located immediately upstream of ESR1, C6ORF96, C6ORF97, and C6ORF211 were highly correlated with ESR1 (Rs = 0.67, 0.64, and 0.55 respectively, FDR

To investigate the use of computerized cardiotocography (cCTG) parameters in Intrauterine Growth Restriction (IUGR) pregnancies for the prediction of 1) complication with preeclampsia; 2) placental histological abnormalities, and 3) neonatal outcomes. A single-center observational retrospective case-control study was performed by reviewing medical records, cCTG databases and pathological reports of women with singleton pregnancy and IUGR uncomplicated (controls) and complicated by preeclampsia (cases). Primary endpoint was the association between cCTG parameters and preeclampsia in IUGR. Secondary endpoints were the association between cCTG parameters and 1) placental abnormalities, and 2) neonatal outcomes. The one-way ANOVA test was used to compare cCTG parameters in cases and controls. t-test was applied to compare neonatal outcomes and placental abnormalities in both groups. The Spearman Test value Correlation coefficients between the cCTG parameters and neonatal outcome in the two groups. A p value < .05 was considered significant for all analyses. Among all cCTG parameters, a significant association with preeclampsia in IUGR was found for Fetal Heart Rate (FHR, p = .008), Delta (p = .018), Short Term Variability (STV, p = .021), Long Term Variability (LTV, p = .028), Acceleration Phase Rectified Slope (APRS, p = .018) and Deceleration Phase Rectified Slope (DPRS, p = .038). Of all placental histologic abnormalities, only vascular alterations at least moderate were significantly associated with increased FHR (p = .02). About neonatal outcomes, all cCTG parameters were significantly associated with birth weight, Apgar index at 1 and 5 min, pH and pCO2. FHR, LTI, Delta, Approximate Entropy (ApEn) and LF were significantly associated with pO2; LTI, Interval Index (II) and ApEn with base excess. Among controls, Delta, ApEn, Low Frequency (LF) and High Frequency (HF) were significantly associated with pCO2, while among cases, STV and Delta were significantly associated with pH; STV, LTI, Delta, ApEn, LF and HF with pCO2; STV, LTI, Delta and ApEn with pO2; HF with base excess; FHR and LF with lactates. cCTG parameters may be useful to detect complication with preeclampsia in IUGR pregnancies. Regarding placental status, cCTG parameters may detect overall circulation alterations, but not specific histological abnormalities. Lastly, all cCTG parameters may predict neonatal outcomes, helping to tailor the patients’ management.

Orientadores: Job Jesus Batista, Bernardino Figueiredo Dissertação (mestrado) - Universidade Estadual de Campinas, Instituto de Geociencias Resumo: O depósito mineral poli metálico do Igarapé Bahia (Cu-Au-Ag-Mo) é hospedado por rochas metavulcânicas e metassedimentares de baixo grau do Grupo Igarapé Bahia na Província Mineral de Carajás, norte do Brasil. O Grupo Igarapé Bahia constitui-se principalmente de rochas vulcânicas básicas e piroclásticas, rochas sedimentares psamopelíticas e formações ferríferas, que exibem direção NNW e mergulhos de 70° ENE. Estas rochas são capeadas por um manto laterítico, o qual hospeda um considerável depósito de ouro na área. O presente trabalho exibe os resultados petrográficos e litogeoquímicos realizados nas rochas vulcânicas básicas do depósito do Igarapé Bahia, assim como os resultados petrográficos da mineralização primária sulfetada associada a estas rochas. Um total de 23 amostras de rochas tiveram seus elementos maiores e traços analisados por Fluorescência de Raio-X, Absorção Atômica e outros métodos analíticos, realizados na UNICAMP e na UNESP. Os teores de ETR foram determinados em 8 amostras de rochas pelo método ICP, na GEOSOL. Estas rochas foram também estudadas microscopicamente e a paragênese do minério foi determinada num total de 25 seções polidas. Os tipos litológicos são: metabasaltos,metadiabásios com intercrescimento granofírico, meta-andesitos a metadacitos, rochas ricas em magnetita, as quais hospedam lentes de sulfeto maciço, e rochas básicas intrusivas que cortam a sequência vulcanosedimentar. No geral, as rochas vulcânicas do Igarapé Bahia foram alteradas hidrotermalmente em condições compatíveis a da facies xisto verde.Todos os tipos litológicos, exceto as rochas básicas intrusivas contêm quantidades variáveis de clorita, carbonato, quartzo e epidoto. Os teores de elementos incompatíveis e ETR obtidos para estas rochas indicam que elas correspondem provavelmente a Tholeiítos Continentais, com relativo enriquecimento em Rb, Ba, K, La e Ce. Este enriquecimento pode ser devido à alteração hidrotermal ou à contaminação crustal. A mineralização primária sulfetada do depósito do Igarapé Bahia sofreu remobilização durante o evento hidrotermal, em condições da faices xisto verde e foi também afetada por evento cisalhante Abstract: The polymetallic Igarapé Bahia mineral deposit (Cu-Au-Ag-Mo) is hosted by the low-grade metavolcanic and metasedimentary roeles of the Igarapé Bahia Group in the Carajás Mineral Province, northern Brazil. The Igarapé Bahia Group consists mainly of basic volcanic and pyroclastic rocks, psamo-pelitic sedimentary rocks and iron formation, which follow a general NNW strike with a dip of 7(1 ENE. These rocks are overlain by a lateritic sequence which hosts the largest gold deposit in the area. The present study reports a petrographic and lithogeochemica1 investigation on the basic volcanic rocks of the Igarapé Bahia deposit, as well as petrographic results on the primary sulfide mineralization associated with these rocks. A total of 23 rock samples were analyzed for both major and trace elements by XRF, ASS and other analytical methods available at UNICAMP and UNESP. REE contents were determined on 8 selected rock samples by ICP method at GEOSOL. These rocks were also studied by conventional optical microscopy and the ore paragenesis were recognized in a total of 25 polished-thin section. Lithologica1 types are: metabasalts, metabasalts with granophyric intergrowths, meta-andesites to metadacites, country rocks with interlayerings of magnetiterich rocks, which host massive sulfide lenses, and intrusive basic rocks crosscutting the volcanic-sedimentary sequence. In general, the Igarapé Bahia volcanic rocks have been hydrotermally altered at greenschist facies conditions. All types, except the subvolcanic basic rocks contain variable amounts of chlorite, carbonate, quartz and epidote. The incompatible element and REE patterns obtained for these rocks resemble those of Continental Tholeiites probably, with relative enrichment for Rb, Ba, k, La and Ce. These enrichment may be due to the hydrothermal alteration or crostal contamination. The primary sulfide mineralization of the Igarapé Bahia deposit underwent local remobilization during hydrothermal alteration events at greenschist facies and was also affected by shearing within a more brittle regime Mestrado Mestre em Geociências

Polycystic ovary syndrome (PCOS) is a complex and heterogeneous endocrine disease. The hypothesis that alterations in the microbiome are involved in the genesis of PCOS has been postulated. Aim of this review is to summarize the available literature data about the relationship between microbiome and PCOS. A search on PubMed and Medline databases was performed from inception to November 20Most of evidence has focused on the connection of intestinal bacteria with sex hormones and insulin-resistance: while in the first case, a relationship with hyperandrogenism has been described, although it is still unclear, in the second one, chronic low-grade inflammation by activating the immune system, with increased production of proinflammatory cytokines which interfere with insulin receptor function, causing IR (Insulin Resistance)/hyperinsulinemia has been described, as well as the role of gastrointestinal hormones like Ghrelin and peptide YY (PYY), bile acids, interleukin-22 and Bacteroides vulgatus have been highlighted. The lower genital tract microbiome would be affected by changes in PCOS patients too. The therapeutic opportunities include probiotic, prebiotics and synbiotics, as well as fecal microbiota transplantation and the use of IL-22, to date only in animal models, as a possible future drug. Current evidence has shown the involvement of the gut microbiome in PCOS, seen how humanized mice receiving a fecal transplant from women with PCOS develop ovarian dysfunction, immune changes and insulin resistance and how it is capable of disrupting the secondary bile acid biosynthesis. A future therapeutic approach for PCOS may involve the human administration of IL-22 and bile acid glycodeoxycholic acid.

ObjectiveSingle cases and small series of Guillain-Barré syndrome (GBS) have been reported during the SARS-CoV-2 outbreak worldwide. We evaluated incidence and clinical features of GBS in a cohort of patients from two regions of northern Italy with the highest number of patients with COVID-19.MethodsGBS cases diagnosed in 12 referral hospitals from Lombardy and Veneto in March and April 2020 were retrospectively collected. As a control population, GBS diagnosed in March and April 2019 in the same hospitals were considered.ResultsIncidence of GBS in March and April 2020 was 0.202/100 000/month (estimated rate 2.43/100 000/year) vs 0.077/100 000/month (estimated rate 0.93/100 000/year) in the same months of 2019 with a 2.6-fold increase. Estimated incidence of GBS in COVID-19-positive patients was 47.9/100 000 and in the COVID-19-positive hospitalised patients was 236/100 000. COVID-19-positive patients with GBS, when compared with COVID-19-negative subjects, showed lower MRC sum score (26.3±18.3 vs 41.4±14.8, p=0.006), higher frequency of demyelinating subtype (76.6% vs 35.3%, p=0.011), more frequent low blood pressure (50% vs 11.8%, p=0.017) and higher rate of admission to intensive care unit (66.6% vs 17.6%, p=0.002).ConclusionsThis study shows an increased incidence of GBS during the COVID-19 outbreak in northern Italy, supporting a pathogenic link. COVID-19-associated GBS is predominantly demyelinating and seems to be more severe than non-COVID-19 GBS, although it is likely that in some patients the systemic impairment due to COVID-19 might have contributed to the severity of the whole clinical picture.

Introduction The prognosis of malignant gliomas remains largely unsatisfactory for the intrinsic characteristics of the pathology and for the delayed diagnosis. Multimodal imaging based on PET and MRI may assess the dynamics of disease onset and progression allowing the validation of preclinical models of glioblastoma multiforme (GBM). The aim of this study was the characterization of a syngeneic rat model of GBM using combined in vivo imaging and immunohistochemistry. Methods Four groups of Fischer rats were implanted in a subcortical region with increasing concentration of rat glioma F98 cells and weekly monitored with Gd-MR, [ 18 F]FDG- and [ 18 F]FAZA-PET starting one week after surgery. Different targets were evaluated on post mortem brain specimens using immunohistochemistry: VEGF, GFAP, HIF-1α, Ki-67 and nestin. Results Imaging results indicated that tumor onset but not progression was related to the number of F98 cells. Hypoxic regions identified with [ 18 F]FAZA and high-glucose metabolism regions recognized with [ 18 F]FDG were located respectively in the core and in external areas of the tumor, with partial overlap and remodeling during disease progression. Histological and immunohistochemical analysis confirmed PET/MRI results and revealed that our model resumes biological characteristics of human GBM. IHC and PET studies showed that necrotic regions, defined on the basis of [ 18 F]FDG uptake reduction, may include hypoxic clusters of vital tumor tissue identified with [ 18 F]FAZA. This last information is particularly relevant for the identification of the target volume during image- guided radiotherapy . Conclusions In conclusion, the combined use of PET and MRI allows in vivo monitoring of the biological modification of F98 lesions during tumor progression.

The objective of this study was to develop new solid self-emulsifying pellets to deliver milk thistle extract (silymarin). These pellets were prepared via extrusion/spheronisation procedure, using a self-emulsifying system or SES (Akoline MCM®, Miglyol®, Tween 80®, soy lecithin and propylene glycol), microcrystalline cellulose and lactose monohydrate. To select the most suitable formulations for extrusion and spheronisation, an experimental design of experiences was adopted. The screening amongst formulations (13 different blends) was performed preparing pellets and evaluating extrusion profiles and quality of the spheronised extrudates. The pellets were characterised for size and shape, density, force required to crush them. Although more than one type of pellets demonstrated adequate morphological and technological characteristics, pellets prepared from formulation 7 revealed the best properties and were selected for further biopharmaceutical investigations, including in vitro dissolution and in vivo trials on rats to study serum and lymph levels after oral administration of the pellets. These preliminary technological and pharmacokinetic data demonstrated that extrusion/spheronisation is a viable technology to produce self-emulsifying pellets of good quality and able to improve in vivo oral bioavailability of main components of a phytotherapeutic extract of more than 100 times by enhancing the lymphatic route of absorption.

Humoral immune mechanisms may have a role in the neurological complications of celiac disease (CD). We assessed 71 CID patients for neurologic manifestations and presence of serum antibodies to neural antigens. Sixteen patients (22.5%) were found to have neurological deficits including headache, depression, entrapment syndromes, peripheral neuropathy, and epilepsy. Antibody reactivity to neural antigens was detected in 30/71 (42.2%) patients. There was no clear correlation between anti-neural reactivity and neurologic dysfunction. Follow-up of 62 patients did not reveal change in electrophysiology or antibodies, regardless of diet. However, in 2 patients with neuropathy, symptoms improved or worsened depending on the diet.

Antibodies to gangliosides and Purkinje cells have been reported in patients with celiac disease (CD) with neuropathy and ataxia, respectively. Whether these antibodies are pathogenic is not clear. The response of neurological symptoms and antibody titers to a gluten-free diet is still controversial. The objective of our study was to assess whether neurological manifestations in CD patients correlate with antibody titers and a gluten-free diet.Thirty-five CD patients (9 males, 26 females, mean age 37.1 +/- 12.6 yrs) were followed prospectively. At initial evaluation, 23 were on a gluten-free diet, 12 were not. At recruitment and during follow-up, patients underwent neurological and electrophysiological evaluation. IgG, IgM, and IgA anti-ganglioside antibodies were assayed by ELISA; anti-neuronal antibodies were assessed by immunohistochemistry and Western blot. Four patients, all males, had electrophysiological evidence of neuropathy; three had been on a gluten-free diet for several months, and one was newly diagnosed. One had reduced tendon reflexes; another complained of distal paresthesias. With regard to anti -ganglioside antibodies, three patients had a moderate increase in antibodies without symptoms or signs of neuropathy. No patients had ataxia or cerebellar dysfunction, although in four patients reactivity to neuronal antigens was found. In 17 patients, an electrophysiological follow-up (mean duration of follow-up, 9 months) showed no changes. In conclusion, the preliminary results of this prospective study indicate that neuropathy, usually subclinical, may accompany CD. Antibody titers do not seem to correlate with neurological symptoms/signs or diet. Ongoing follow-up will help confirm these data and clarify the role, if any, of antibodies in neurological involvement in CD.

We report here clinical, electrophysiological, and molecular findings in a family affected with two inherited genetic diseases: limb girdle muscular dystrophy type 1B (LGMD1B) and hereditary neuropathy with liability to pressure palsies (HNPP). Members of the family carry a novel missense mutation in the LMNA gene and a nonsense mutation in the PMP22 gene. Interestingly, the double LMNA/PMP22 mutations carriers showed clinical features more severe than usually seen in HNPP, and electrophysiological findings suggesting an axonal loss in addition to a typical myelinopathy. This study provides further insights into the relevance of lamin A/C in muscle and nerve.

Chemotherapy has been used for treating chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with incosistent results. Chemotheraphy has been used for treating with inconsistent results. Rituximab is a chimeric monoclonal antibody directed against the CD20 antigen, used to treat B-cell lymphoma and reported to be effective in some neuropathies with IgM autoreactivity. We saw a 72-year-old man with CIDP refractory to steroids, plasma exchange, IV Ig, and cyclosporin. He was unable to walk; severe impairment was present also at the upper limbs. Electrodiagnostic studies revealed slowing of motor and sensory conduction velocities, and prolonged distal motor latencies. Immunoelectrophoresis evidence an IgM/k monoclonal gammopathy. Antibodies to Myelin Associated Glycoprotein (MAG) and other peripheral nerve antigens were negative. Bone marrow biopsy documented a small lymphocytic B-cell lymphoma (CD20+). Treated with Rituximab (375 mg/m2 for 4 weeks), the patient presented at follow-up evaluations (3, 6 and 8 months later) a progressive improvement. Eventually, he was able to walk, and regained full strength at upper limbs. Consistently, electrophysiological studies improved. We suggest considering treatment with Rituximab in CIDP resistant to conventional therapy, at least in cases associated with IgM lymphoproliferative diseases.

The clinical and neurophysiologic data from 65 patients taking thalidomide were reviewed. Thalidomide sensory neurotoxicity was found to be cumulative dose dependent but occurs only when the total dose is relatively high (>20 g). The risk of developing sensory neuropathy is around 10% below this threshold but increases with higher doses.

- Abstract
Extracts from locally grown aromatic plants can enhance the geographical characteristics and microbial stability of craft beers, which are often not pasteurized or filtered. Here, the chemical and antimicrobial properties of aqueous extracts from leaves of Myrtus communis L., Pistacia lentiscus L., Artemisia arborescens L., and floral wastes of Crocus sativus L., all cultivated in Sardinia (Italy), were assessed. P. lentiscus extract had the highest polyphenol content (111.20 mg GAE/g), followed by M. communis (56.80 mg GAE/g), C. sativus (32.80 mg GAE/g), and A. arborescens (8.80 mg GAE/g). Notably, only the M. communis extract demonstrated significant inhibitory activity against pathogenic and spoilage microorganisms, with minimum inhibitory concentrations of 0.18, 0.71, and 1.42 mg GAE/mL against Staphylococcus aureus , Lactiplantibacillus plantarum , and Lacticaseibacillus casei , respectively. Additionally, it reduced the growth of Levilactobacillus brevis and Fructilactobacillus lindneri at concentrations of 0.35 and 0.71 mg GAE/mL, respectively. Based on its significant antimicrobial activity, the M. communis extract was further characterized using high-resolution mass spectrometry, revealing high abundances of nonprenylated phloroglucinols, flavonoid derivatives (myricetin), and quinic acids. Lastly, adding M. communis extract (2.84 mg GAE/mL) to commercial beer effectively prevented the growth of L. brevis and F. lindneri , showing its potential to avoid beer's microbial spoilage.

- Abstract
The societal reintegration of individuals with criminal records, particularly involving sexual offenses, faces challenges due to moral condemnation. Professionals' perspectives are pivotal in facilitating this reintegration process. This study surveyed 314 psychologists via a web-based experiment to assess their judgments regarding allegations of sexual violence and perpetrator's denial. Psychologists with experience in working with individuals convicted of sexual offenses showed a decreased propensity to grant prison benefits upon the progressive disclosure of the sexual offense, which diminished further in the presence of denial. For psychologists lacking such professional experience, judgment worsened solely with the discovery of the sexual offense, but not with denial. Psychologists not experienced in working with individuals with sexual convictions were generally found to have higher levels of malignant satisfaction than their experienced counterparts. Additionally, experienced psychologists exhibited a greater willingness to manage forensic cases and endorsed the effectiveness of treatment, while non-experts displayed less confidence in treatment efficacy, hesitancy in working with such individuals, and a propensity to delegate the case. Availability to handle the case diminished as more information surfaced for both groups. These findings highlight differences in professionals' attitudes based on experience and suggest implications for understanding punitive attitudes towards individuals with sexual convictions., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Intimate partner violence (IPV) encompasses physical, sexual, or psychological abuse. Recent evidence suggests that victims and perpetrators might share some common psychological characteristics. Particularly, high levels of alexithymia, a difficulty in identifying and expressing emotions, and an externally oriented thinking style were found in both victims and perpetrators when compared to the general population. This systematic review and meta-analysis aimed to quantify the levels of alexithymia in victims and perpetrators of IPV and compare these levels to controls. We systematically searched PubMed, PsycINFO, Web of Science, and Scopus databases, using the following strings: ("intimate partner violence" OR "IPV" OR "partner abuse") AND ("alexithymia" OR "alexithymic"). The inclusion criteria were: adult perpetrators or victims of IPV; with or without a rehabilitation program; having or not a comparison group from the general population; alexithymia as outcome; all types of study design. Seventeen studies met the inclusion criteria. Data were meta-analyzed with random-effects models. Results showed comparable levels of alexithymia in victims and perpetrators of IPV (mean = 55.92 vs. 55.15, respectively). Furthermore, we found increased alexithymia in victims (Hedges' g, 0.87 [95% CI 0.43, 1.31]) and perpetrators (Hedges' g, 0.94 [95% CI 0.77, 1.12]) compared to controls. These results highlight that both perpetrators and victims exhibited high levels of alexithymia. A deeper understanding of this psychological dimension can help professionals to plan better-tailored interventions, in which all relevant factors associated with IPV are considered., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.
