Effects of mindfulness meditation on conscious and non-conscious components of the mind
The aim of the present review is to investigate previous studies concerning the effects of meditation and dispositional mindfulness on conscious and implicit or non-conscious attitudes. First we present a brief perspective on conscious and non-conscious states of mind. Then we introducethefundamentalbasesofmindfulnessmeditation. Third we review studies on dispositional mindfulness and meditation that employed either direct or indirect measures to assess explicit and implicit attitudes. Finally, we briefly present how meditation has been associated with the psychotherapeutic practice of psychoanalysis and, hence, as a therapeutic technique to access the unconscious. Until now, few studies have investigated the impact of meditation on non-conscious states of mind and personality; nevertheless, both scientific studies involving implicit measures and reflections from psychotherapy have underlined the importance of meditation in promoting psychological well-being, leading to de-automatization of automatic patterns of responding and to higher levels of self-awareness
Teachers’ Professional Development on Media and Intercultural Education. Results from some participatory research in Europe
Media and intercultural education are being increasingly recognised as a fundamental competence for teachers of the 21st century. Digital literacy and civic competence are facing several new challenges in response to the intensification of migratory phenomena and the unprecedented spread of fake news, especially among adolescents at risk of social exclusion, but teachers’ professional development is still far from coping with this emerging need. Intercultural understanding and a critical use of media among adolescents have now become primary goals for the promotion of active citizenship. This article intends to provide some recommendations on how to support teachers’ professional development in the field of media and intercultural education. To this purpose, it presents and discusses the results of an action-research project aimed at teachers’ improvement of teaching skills about the media in multicultural public schools. The results are part of a larger European project “Media Education for Equity and Tolerance” (MEET) (Erasmus Plus, KA3), an initiative promoted in 2016–2018 by the University of Florence (Italy)
Adherence to drug treatment in hypertensive patients on the Family Health Program
The aim of the present study was to analyze adherence to drug treatment in hypertensive patients enrolled on the Family Health Program in Ribeirão Preto, São Paulo State. This transversal study was conducted between August and December 2006, in which 109 patients were interviewed using the Morisky and Green Test to measure adherence level to pharmacotherapy. Variables that may be related to adherence level were also investigated, such as demographic characteristics, health care team and health service related factors, and pharmacotherapy related factors. The test scores were analyzed by two criteria: patients were categorized as "more adherent" if they had a score from 3 to 4 (criterion 1) or a score of 4 (criterion 2); patients with other scores were categorized as less adherent. Of all patients, 79.8% and 43.1% were classified as "more adherent" according to criterion 1 and criterion 2, respectively. With regard to the possible causes of non-adherence to treatment, statistically significant (p<0.05) associations were identified between "trust in the doctor" or "number of antihypertensive drugs used" and the level of adherence, according to criterion 2. These results indicated adequate adherence levels to drug treatment by the patients, and highlighted the importance of professional/patient interaction, trust in the doctor and the attitude by health professionals toward users.Este estudo teve como objetivo estudar a adesão ao tratamento farmacológico de pacientes hipertensos seguidos no Programa de Saúde da Família em Ribeirão Preto, SP. Realizou-se um estudo transversal entre agosto e dezembro de 2006, em que foram entrevistados 109 pacientes, utilizando-se o Teste de Morisky e Green para mensurar o grau de adesão ao tratamento. Variáveis que podem se relacionar com o grau de adesão também foram estudadas, tais como: características demográficas, fatores relacionados à equipe e ao serviço de saúde e à terapia medicamentosa. Os resultados do teste foram avaliados por dois critérios: os pacientes foram classificados como "mais aderentes" se apresentassem pontuação de 3 a 4 (critério 1) ou de 4 (critério 2); pacientes com outras pontuações foram classificados como "menos aderentes". Dos pacientes, 79,8% e 43,1% foram "mais aderentes" de acordo com os critérios 1 e 2, respectivamente. Em relação às possíveis causas da não adesão, observaram-se associações significativas (p<0,05) entre as variáveis "confiança no médico" ou "quantidade de medicamentos anti-hipertensivos que utiliza" e "grau de adesão", pelo critério 2. Os resultados do presente trabalho indicam que os pacientes apresentam graus satisfatórios de adesão ao tratamento medicamentoso, a importância da interação profissional/paciente, a confiança no médico e a atitude dos profissionais de saúde em relação ao usuário
Temperament and Character Effects on Late Adolescents' Well-Being and Emotional-Behavioural Difficulties
Background. Research on adults points to personality as a crucial determinant of well-
being. The present study investigates the question of personality's relation to well-being
and psychosocial adjustment in adolescence.
Methods. We assessed the role of temperament and character (Temperament and
Character Inventory, TCI-125), on psychological well-being (PWB; Psychological Well-
Being scales), subjective well-being (SWB; Positive and Negative Affect, PA and NA,
respectively), and psychosocial adjustment (emotional-behavioural problems measured
by the Strengths and Difficulties Questionnaire for Adolescents, SDQ-A), in 72 Italian
late adolescents (aged 17.5 0.75). Multiple regressions were conducted to predict
PWB, SWB, and SDQ-A scores using TCI-125 scales as predictors.
Results. Character maturity, and in particular Self-Directedness, had a widespread
protective effect on well-being and psychosocial adjustment, while different strengths
and emotional-behavioural difficulties were associated to specific temperamental
and character traits. For example, Harm-Avoidance and Novelty-Seeking positively
predicted internalized and externalized problems, respectively.
Discussion. The present results suggest the usefulness of continuing to evaluate
temperament and, in particular, character dimensions in investigations focused on
adolescents' well-being and psychosocial functioning, especially in the contexts of
potential interventions aimed at enhancing development of adolescents' character
dimensions at the intrapersonal, interpersonal, and transpersonal levels
The Impact of the COVID-19 Pandemic on Affect, Fear, and Personality of Primary School Children Measured During the Second Wave of Infections in 2020
In relation to the COVID-19 pandemic outbreak, a large body of research has identified a negative impact on individuals' affectivity, frequently documented by increased prevalence of anxiety and depression symptoms. For children, this research was less extensive, was mainly based on caregivers' reports and neglected personality assessment. In order to measure the impact of the pandemic, and the fears it caused, on primary school children's affect and personality, 323 (180 boys and 143 girls) Italian third, fourth and fifth graders were assessed between October and November 2020, namely during the second wave of COVID-19 infections in Italy, with validated self-reports of affect (Positive and Negative Affect Scale for Children, PANAS-C), fear of COVID-19 (Fear of COVID-19 Scale, FCV-19S) and personality (junior Temperament and Character Inventory, jTCI). In comparison with PANAS-C and jTCI normative scores collected prior to the pandemic, data obtained from children in 2020 showed unchanged affect scores in the overall sample, a decrease of Positive Affect in girls, and a decrease in the Harm Avoidance and an increase in the Self-Transcendence scales of personality. Fear of COVID-19 scores were positively correlated with Negative Affect scores and negatively predicted by children's personality profile of resilience (calculated using scores on the Harm Avoidance and the Self-Directedness scales of personality). These results suggested that Italian primary school children, especially boys, maintained their pre-pandemic levels of affect (or restored them after the first COVID-19 wave) and partially diverged from the typical development of personality in an apparently positive sense, namely toward more courageous/optimistic and spiritual profiles. This sort of children's post-traumatic growth might also be attributed to children's family and education systems, which should continue to be supported to promote and maintain community mental health
Penetration of Sodium Hypochlorite Modified with Surfactants into Root Canal Dentin
Abstract The aim of this study was to evaluate the effect of concentration, exposure time and temperature of sodium hypochlorite (NaOCl) added with surfactants on its penetration into dentinal tubules. Sixty-five extracted human permanent maxillary anterior teeth with single canals were prepared by ProTaper SX hand-operated instruments. The teeth were then sectioned perpendicular to the long axis. The crowns and apical thirds of all the teeth were removed. The remaining roots were processed into 4-mm-long blocks and stained overnight in crystal violet. One hundred and thirty stained blocks were further split into halves and treated by nine different types of NaOCl-based solutions. Three solutions were added with surfactants (Hypoclean, H6, Chlor-Xtra) and the others were regular hypochlorites at increasing concentrations (1%, 2%, 4%, 5.25%, <6%, 6% NaOCl) from different brands. The dentin blocks were exposed to the solutions for 2, 5, and 20 min at 20 °C, 37 °C and 45 °C, respectively. The depth of NaOCl penetration was determined by bleaching of the stain and measured by light microscopy at 20 and 40. Statistical comparisons were made by using a generalized linear model with Bonferroni's post-hoc correction. The shortest penetration (81±6.6 μm) was obtained after incubation in 1% NaOCl for 2 min at 20 °C; the highest penetration (376.3±3.8 μm) was obtained with Chlor-Xtra for 20 min at 45 °C. Varying NaOCl concentration produced a minimal effect while temperature and exposure time had a significant direct relationship with NaOCl penetration into dentinal tubules, especially those with lowered surface tension. The exposure time and temperature of sodium hypochlorite as well as the addition of surfactants may influence the penetration depth of irrigants into dentinal tubules
Loss of chondroprotection of medial collagen meniscus implant (CMI) at 20-year follow-up
Objective: The mid-term results of the collagen meniscus implant (CMI) procedure for the replacement of partial meniscus defects have already been described. However, there is a paucity of long-term comparative studies. This study aimed to compare the clinical outcomes, failures, and osteoarthritis progression of patients who underwent partial medial meniscectomy and medial CMI implantation. Methods: Thirty-six nonconsecutive patients with medial meniscus injuries that underwent medial CMI (MCMI) implantation or partial medial meniscectomy (PMM) between 1997 and 2000 were included in a prospective study with an intermediate 10-year follow-up examination and a final follow-up examination at 20-year follow-up. Outcome measures at the 20-year follow-up included the Lysholm score, visual analogue scale (VAS) for pain, International Knee Documentation Committee (IKDC) knee form , and Tegner activity level. Bilateral weight-bearing radiographs were also performed to evaluate hip-knee-angle (HKA) and the medial joint line height (JL). Data regarding complications and failures were also collected. Results: At the 20-year follow-up, 31 patients (83% follow-up rate) with a mean age of 60.7 ± 8.9 years were included in the final analysis (21.1 ± 1.2 years follow-up). Four reoperations and one failure per group were reported. When comparing the clinical results of the two groups, no difference was found considering the Lysholm score, Knee Injury and Osteoarthritis Outcome Score (KOOS), Tegner, and the IKDC. Moreover, 20 patients underwent radiographic examination (10 MCMI, 10 MM), and no statistically significant difference was reported concerning the JL, HKA, and the presence and incidence of osteoarthritis between the two groups. Conclusion: The CMI implant for partial medial meniscectomy provided good long-term results and a low failure rate. However, differently from the 10 years follow-up, the clinical and the radiological outcomes were not superior compared to the medial meniscectomy group. The present study's result suggests that using a medial scaffold is not chondroprotective. Level of evidence: III, Prospective case-control study
Comparison of P2X and TRPV1 receptors in ganglia or primary culture of trigeminal neurons and their modulation by NGF or serotonin
BACKGROUND: Cultured sensory neurons are a common experimental model to elucidate the molecular mechanisms of pain transduction typically involving activation of ATP-sensitive P2X or capsaicin-sensitive TRPV1 receptors. This applies also to trigeminal ganglion neurons that convey pain inputs from head tissues. Little is, however, known about the plasticity of these receptors on trigeminal neurons in culture, grown without adding the neurotrophin NGF which per se is a powerful algogen. The characteristics of such receptors after short-term culture were compared with those of ganglia. Furthermore, their modulation by chronically-applied serotonin or NGF was investigated. RESULTS: Rat or mouse neurons in culture mainly belonged to small and medium diameter neurons as observed in sections of trigeminal ganglia. Real time RT-PCR, Western blot analysis and immunocytochemistry showed upregulation of P2X(3 )and TRPV1 receptors after 1–4 days in culture (together with their more frequent co-localization), while P2X(2 )ones were unchanged. TRPV1 immunoreactivity was, however, lower in mouse ganglia and cultures. Intracellular Ca(2+ )imaging and whole-cell patch clamping showed functional P2X and TRPV1 receptors. Neurons exhibited a range of responses to the P2X agonist α, β-methylene-adenosine-5'-triphosphate indicating the presence of homomeric P2X(3 )receptors (selectively antagonized by A-317491) and heteromeric P2X(2/3 )receptors. The latter were observed in 16 % mouse neurons only. Despite upregulation of receptors in culture, neurons retained the potential for further enhancement of P2X(3 )receptors by 24 h NGF treatment. At this time point TRPV1 receptors had lost the facilitation observed after acute NGF application. Conversely, chronically-applied serotonin selectively upregulated TRPV1 receptors rather than P2X(3 )receptors. CONCLUSION: Comparing ganglia and cultures offered the advantage of understanding early adaptive changes of nociception-transducing receptors of trigeminal neurons. Culturing did not prevent differential receptor upregulation by algogenic substances like NGF or serotonin, indicating that chronic application led to distinct plastic changes in the molecular mechanisms mediating pain on trigeminal nociceptors
High survivorship rate and good clinical outcomes after high tibial osteotomy in patients with radiological advanced medial knee osteoarthritis: a systematic review
IntroductionThe role of valgus producing high tibial osteotomy (HTO) for the treatment of advanced knee osteoarthritis (OA) is still controversial. The aim of the current systematic review was to assess survivorship and patient-reported outcomes (PROMs) of high tibial osteotomy in patients with radiological advanced medial knee OA.MethodsA systematic search of PubMed, Cochrane and EMBASE database was performed in July 2023 in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines. Inclusion and exclusion criteria were applied to identify studies investigating the survivorship rate and PROMs of valgus-producing high tibial osteotomy in patients with advanced knee OA at x-ray assessment in the medial compartment at minimum-two-years follow up. Advanced radiological OA was defined as Kellgren Lawrence (K-L) >= 3 or Ahlbach >= 2. Survivorship was defined as percentage of patients free of total knee arthroplasty (TKA) at follow-up. Clinical interpretation of provided PROMs were performed according to minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) target values reported in literature. Survivorship data and PROMs scores were extracted, and studies were stratified based on selected study features. The quality of included studies was assessed with modified Coleman score.ResultsA total of 18 studies, totalling 1296 knees with a mean age between 46.9 and 67 years old, were included. Average survivorship was of 74.6% (range 60 - 98.1%) at 10-years follow up. The subjective scoring systems showed good results according to MCID and PASS, and postoperative improvements were partially maintained until final follow-up.ConclusionHTO is worth considering as treatment choice even in patients affected by radiological advanced medial knee osteoarthritis. Long term survivorship and good patient reported clinical outcomes could be expected in this population.Level of evidenceIV; systematic review of level III-IV studies
Prevalence of Peri-Implantitis: A Multi-Centered Cross-Sectional Study on 248 Patients
The aim of this multicenter cross-sectional study was to determine the prevalence of peri-implantitis and to assess its association with several patient- and implant-related factors. Patients with at least one implant, who came for a recall visit to one of the four centers over a period of five months, were enrolled. Presence of peri-implantitis (defined as bleeding on probing, exudate/suppuration, bone loss > 0.2 mm/year and increased pocket depth) and several other variables (e.g., smoking habits, history of periodontitis, diabetes) were recorded. Out of 248 enrolled patients (1162 implants), 10 patients had at least one implant with peri-implantitis (4.03%); a total of 14 implants were affected (1.20%). A statistically significant association between peri-implantitis and diabetes was found (OR 8.65; CI: 1.94–38.57). Smoking more than 10 cigarettes per day (OR: 0.53; CI 0.03–9.45) and history of periodontitis (OR: 2.42; CI: 0.49–11.89) were not found to be statistically associated with peri-implantitis. Even if implant therapy is a consolidated treatment, biological complications do happen. Strict supportive therapy recalls could lead to lower rates of peri-implantitis and earlier diagnosis
