RESUMO

INTRODUCTION: The oncoplastic conservative surgery was developed as a natural evolution of traditional surgery, attempting to improve the therapeutic and aesthetic outcomes where tumor resection could be followed by not-adequate results. Our primary aim is to evaluate how patient satisfaction and quality-of-life after conservative oncoplastic surgery, using BREAST-Q (BCT Module), change pre- and post-operatively. The secondary aim is to compare patient-reported outcome after oncoplastic or traditional conservative surgery. PATIENTS AND METHODS: We enrolled 647 patients who underwent traditional conservative surgery or oncoplastic surgery from January 2020 to December 2022. Only 232 women (35.9%) completed the BREAST-Q questionnaire on a web-based platform, at the preoperative phase and 3 months after treatment. RESULTS: The average score of "Psychosocial well-being" and "Satisfaction with Breasts" 3 months after surgery showed a statistically significant improvement, while the average score for "Physical well-being: Chest" at 3 months showed a worsening compared to the baseline. "Sexual well-being" did not show statistically significant change. A significant difference between the post-operative outcome of oncoplastic surgery and traditional surgery was observed only for Physical well-being (better for traditional surgery). CONCLUSIONS: The study showed significant improvement in patient-reported outcomes 3 months after the surgery, except for physical discomfort that increases especially after oncoplastic surgery. Furthermore, our data, as well as many others, point to the appropriateness of using OCS where there is an effective indication, while the perspective of patients cannot find significant superiority over TCS in any of the areas analyzed.

RESUMO

The Health Sciences Foundation has assembled a multidisciplinary group around a series of questions about the impact of the COVID-19 pandemic on the mental health of the general population and specific groups within that population, particularly healthcare workers. In the general population, the most prevalent mental disorders have been anxiety, sleep disorders and affective disorders, primarily depression. There has been a considerable increase in suicidal behavior, especially in young women and men over 70 years of age. There has been an increase in alcohol abuse and nicotine, cannabis and cocaine use. In contrast, the use of synthetic stimulants during periods of confinement has decreased. With regard to non-substance addictions, gambling was very limited, pornography consumption increased significantly and there was an increase in compulsive shopping and the use of video games. Particularly vulnerable groups include adolescents and patients with autism spectrum disorders. Healthcare workers suffered an increase in depression, anxiety and post-traumatic stress, especially those who were exposed during the early stages of the pandemic. Female sex, being a nurse, proximity to patients with COVID-19, working in a rural environment and having previous psychiatric or organic illnesses were some of the most frequently repeated factors in various studies in this population group. The media have shown a good degree of knowledge about these problems and have dealt with them frequently and from the point of view of ethics, crisis situations, such as the one experienced, have triggered not only physical but also moral claudications.

RESUMO

Craniofacial and jaw bones have unique physiological specificities when compared to axial and appendicular bones. However, the molecular profile of the jaw osteoblast (OB) remains incomplete. The present study aimed to decipher the bone site-specific profiles of transcription factors (TFs) expressed in OBs in vivo. Using RNA sequencing analysis, we mapped the transcriptome of confirmed OBs from 2 different skeletal sites: mandible (Md) and tibia (Tb). The OB transcriptome contains 709 TF genes: 608 are similarly expressed in Md-OB and Tb-OB, referred to as "OB-core"; 54 TF genes are upregulated in Md-OB, referred to as "Md-set"; and 18 TF genes are upregulated in Tb-OB, referred to as "Tb-set." Notably, the expression of 29 additional TF genes depends on their RNA transcript variants. TF genes with no previously known role in OBs and bone were identified. Bioinformatics analysis combined with review of genetic disease databases and a comprehensive literature search showed a significant contribution of anatomical origin to the OB signatures. Md-set and Tb-set are enriched with site-specific TF genes associated with development and morphogenesis (neural crest vs. mesoderm), and this developmental imprint persists during growth and homeostasis. Jaw and tibia site-specific OB signatures are associated with craniofacial and appendicular skeletal disorders as well as neurocristopathies, dental disorders, and digit malformations. The present study demonstrates the feasibility of a new method to isolate pure OB populations and map their gene expression signature in the context of OB physiological environment, avoiding in vitro culture and its associated biases. Our results provide insights into the site-specific developmental pathways governing OBs and identify new major OB regulators of bone physiology. We also established the importance of the OB transcriptome as a prognostic tool for human rare bone diseases to explore the hidden pathophysiology of craniofacial malformations, among the most prevalent congenital defects in humans.

RESUMO

PURPOSE: The aim of this study was to compare tracheal intubation conditions after induction of anesthesia with a bolus of propofol-sufentanil or propofol-remifentanil and a rapid induction technique. MATERIAL AND METHODS: A total of 70 patients (American Society of Anesthesiologists (ASA) classification I­II) undergoing outpatient surgery under general anesthesia with intubation for tooth extraction were randomly assigned to two groups in this double-blind study. Patients received either a bolus of remifentanil (3 µg/kg) or sufentanil (0.3 µg/kg) together with 2.5 mg/kg propofol for intubation. The primary outcome was the percentage of excellent intubation conditions and the secondary outcomes were the percentage of patients with a decrease of over 20% in mean arterial pressure (MAP) or heart rate (HR), time to achieve spontaneous respiration, time between the end of surgery and extubation and time to achieve an Aldrete score of 10. VAS pain score was >3 or having laryngeal pain 15 min after arriving in the postanesthesia care unit (PACU) were also analyzed. RESULTS: Intubating conditions (perfect + good conditions) were significantly better with remifentanil than with sufentanil (88.5% vs. 68.6%; p = 0.01). When using remifentanil, the hemodynamic conditions were good. Using remifentanil did not significantly increase the pain score or the laryngeal pain in the recovery room. This was confirmed by no significant differences between the groups for morphine consumption. Remifentanil significantly decreased the time to achieve an Aldrete score of 10. CONCLUSION: When intubation without muscle relaxants is required, intubating conditions are much better when a remifentanil bolus is used compared to a sufentanil bolus. The remifentanil/propofol rapid induction technique is a valuable technique to quickly intubate and achieve good conditions.

RESUMO

Interscalene brachial plexus block provides analgesia for shoulder surgery but is associated with hemidiaphragmatic paralysis. Before considering a combined suprascapular and axillary nerve block as an alternative to interscalene brachial plexus block, evaluation of the incidence of diaphragmatic dysfunction according to the approach to the suprascapular nerve is necessary. We randomly allocated 84 patients undergoing arthroscopic shoulder surgery to an anterior or a posterior approach to the suprascapular nerve block combined with an axillary nerve block using 10 ml ropivacaine 0.375% for each nerve. The primary outcome was the incidence of hemidiaphragmatic paralysis diagnosed by ultrasound. Secondary outcomes included: characterisation of the hemidiaphragmatic paralysis over time; numeric rating scale pain scores; oral morphine equivalent consumption; and patient satisfaction. The incidence of hemidiaphragmatic paralysis was 40% (n = 17) vs. 2% (n = 1) in the anterior and posterior groups, respectively (p < 0.001). In one third of patients with hemidiaphragmatic paralysis, it persisted beyond the eighth hour. The median (interquartile range [range]) oral morphine equivalent consumption was significantly higher in the posterior approach when compared with the anterior approach, whether in the recovery area (20 [5-31 (0-60)] mg vs. 7.5 [0-14 (0-52)] mg, respectively; p = 0.004) or during the first 24 h (82 [61-127 (12-360) mg] vs. 58 [30-86 (0-160)] mg, respectively; p = 0.01). Patient satisfaction was comparable between groups (p = 0.6). Compared with the anterior approach, diaphragmatic function is best preserved with the posterior needle approach to the suprascapular nerve block.

RESUMO

One of the goals of immediate breast reconstruction (IBR) is to satisfy the patient's outcome. Recent studies therefore tended to focus on the patient's perception of the care and on the impact on quality of life using patients-reported-outcome-measures (PROMs), able to measure the health status directly without the clinician's interposition. We present a preliminary prospective study on 333 patients who underwent mastectomy with IBR in a two-year period, in a single Italian centre, using a dedicated PROMs, the BREAST-Q™, to determine the patient's satisfaction. We studied two groups of IBR: Group A (two-step with tissue-expander) and Group B (one-step: prosthesis/mesh) and conducted a pre- and post-operative comparison for each group to evaluate score-gain over time, and a group-score comparison to determine whether differences were significant between reconstruction types. Two-hundred-and-nine were actually enrolled and 132 completed all the questionnaires. The response rate was 62.8% and the compliance rate (completion of all the questionnaires) was 63.1%. In both groups all the analyzed domains worsened comparing the pre and post-operative period; the differences were statistically significant only for physical and sexual-wellbeing. In the comparison between the two groups, none of the detected differences reached the statistical significance. According to our experience, we can state that PROMs could improve the health concept redefining the variables to be monitored even if data is still insufficient to draw any definitive conclusion. PROMs can help surgeons and patients decide the most appropriate surgery for a particular patient-profile and to identify those who require further support.

RESUMO

Sickle cell disease is one of the most common autosomal recessive genetic diseases. It gives rise to abnormally shaped red blood cells with altered function, the primary clinical features being haemolytic anaemia and vascular occlusion. Acute complications are frequent and variable and include chest syndrome, stroke, infection mainly due to asplenia, bone pain and priapism. Other chronic complications which can occur are bone necrosis, nephropathy and heart, lung and skin disorders. Oral lesions are also very common and include aseptic pulp necrosis, mucosal damage due to anaemia, fungal infections due to numerous antibiotic therapies, dental eruption delays, bone pain and osteomyelitis of the maxilla, and oral neuropathies, including of the mental nerve of the chin. The oral care of sickle cell patients requires specific precautions such as good management of local anaesthetics, rigorous anti-infective prophylaxis as well as controlled prescription of analgesics. Regular oral follow-up of sickle cell patients is necessary.

RESUMO

The lack of suitable materials solutions stands as a major challenge for the development of advanced nuclear systems. Most issues are related to the simultaneous action of high temperatures, corrosive environments and radiation damage. Oxide nanoceramics are a promising class of materials which may benefit from the radiation tolerance of nanomaterials and the chemical compatibility of ceramics with many highly corrosive environments. Here, using thin films as a model system, we provide new insights into the radiation tolerance of oxide nanoceramics exposed to increasing damage levels at 600 °C -namely 20, 40 and 150 displacements per atom. Specifically, we investigate the evolution of the structural features, the mechanical properties, and the response to impact loading of Al2O3 thin films. Initially, the thin films contain a homogeneous dispersion of nanocrystals in an amorphous matrix. Irradiation induces crystallization of the amorphous phase, followed by grain growth. Crystallization brings along an enhancement of hardness, while grain growth induces softening according to the Hall-Petch effect. During grain growth, the excess mechanical energy is dissipated by twinning. The main energy dissipation mechanisms available upon impact loading are lattice plasticity and localized amorphization. These mechanisms are available in the irradiated material, but not in the as-deposited films.

RESUMO

AIMS: The biostimulant effect of Trichoderma spp. on horticultural crops are highly variable. Thus, practical use of Trichoderma sp. requires feasible formulated products and suitable substrates. METHODS AND RESULTS: This study evaluates the survival and the growth-promotion effect of a Trichoderma saturnisporum rice formulation compared with a nonformulated conidia suspension (seven treatments in total), on tomato, pepper and cucumber seedlings grown in two substrates: (i) rich in organic matter (OM) and (ii) mineral substrate without OM. The results showed beneficial effects on seedling growth in the OM-rich substrate when T. saturnisporum rice formulation (mainly at maximum concentration) was applied, but the effects were opposite when the mineral substrate without OM was used. The effects were closely linked to the level of inoculum in the substrate, which was greater upon application of the formulated inoculum as opposed to the nonformulated one. CONCLUSIONS: The use of rice to prepare the inoculum of T. saturnisporum seems to be promising for seedling growth in the nursery when it is applied in a substrate that is rich in organic matter, but it must be considered that under certain conditions of food shortage, Trichoderma sp. could show pathogenicity to seedlings. SIGNIFICANCE AND IMPACT OF THE STUDY: This study provides evidence of the complexity inherent in the use of micro-organisms in agriculture, while also confirming that the activity of the biofertilizers based on Trichoderma depends on the type of inoculum and its concentration, as well as the properties of the medium in which the fungi develop. Further studies assessing the effectiveness or possible pathogenicity of Trichoderma in different soils under greenhouse conditions must be addressed.

RESUMO

Our objectives for this study were to understand the biological basis of meat tenderness and to provide an overview of the gene expression profiles related to meat quality as a tool for selection. Through deep mRNA sequencing, we analyzed gene expression in muscle tissues of two Italian cattle breeds: Maremmana and Chianina. We uncovered several differentially expressed genes that encode for proteins belonging to a family of tripartite motif proteins, which are involved in growth, cell differentiation and apoptosis, such as TRIM45, or play an essential role in regulating skeletal muscle differentiation and the regeneration of adult skeletal muscle, such as TRIM32. Other differentially expressed genes (SCN2B, SLC9A7 and KCNK3) emphasize the involvement of potassium-sodium pumps in tender meat. By mapping splice junctions in RNA-Seq reads, we found significant differences in gene isoform expression levels. The PRKAG3 gene, which is involved in the regulation of energy metabolism, showed four isoforms that were differentially expressed. This distinct pattern of PRKAG3 gene expression could indicate impaired glycogen storage in skeletal muscle, and consequently, this gene very likely has a role in the tenderization process. Furthermore, with this deep RNA-sequencing, we captured a high number of expressed SNPs, for example, we found 1462 homozygous SNPs showing the alternative allele with a 100% frequency when comparing tender and tough meat. SNPs were then classified into categories by their position and also by their effect on gene coding (174 non-synonymous polymorphisms) based on the available UMD_3.1 annotations.

RESUMO

Chianina and Maremmana breeds play an important role in the Italian cattle meat market. The Chianina breed is an ancient breed principally raised for draught. Now this breed is the worldwide recognized producer of top quality beef, tasteful and tender, specifically the famous "Florentine steak". The Maremmana characterized by a massive skeletal structure, is a rustic cattle breed selected for adaptability to the marshy land of the Maremma region. We used a high throughput mRNA sequencing to analyze gene expression in muscle tissues of two Italian cattle breeds, Maremmana (MM) and Chianina (CN) with different selection history. We aim to examine the specific genetic contribution of each breed to meat production and quality, comparing the skeletal muscle tissue from Maremmana and Chianina. Most of the differentially expressed genes were grouped in the Glycolysis/Gluconeogenesis pathways. The rate and the extent of post-mortem energy metabolism have a critical effect on the conversion of muscle to meat. Furthermore, we aim at discovering the differences in nucleotide variation between the two breeds which might be attributable to the different history of selection/divergence. In this work we could emphasize the involvement of pathways of post-mortem energy metabolism. Moreover, we detected a collection of coding SNPs which could offer new genomic resources to improve phenotypic selection in livestock breeding program.

RESUMO

Neural crest (NC)-derived stem cells (NCSC) have an exceptionally wide differentiation potential, but their use in regenerative therapy has been hampered by their scarcity in adult tissues and complex isolation protocols. Human oral mucosal gingiva may provide an attractive source of these cells as it contains NC-derived cells, the tissue is easily accessible and wound healing is fast and scarless with very little morbidity. To this end, we first investigated whether NC-derived cells are retained in adult gingiva by examining 8-months-old NC-reporter Wnt1-Cre/R26RYFP mice. We then hypothesised that gingival cell NC-like phenotype can be further enhanced by floating neurosphere cultures generated from standard human gingival fibroblast (GF) and pooled CFU-F (GSC) cultures. Findings showed that NC-derived cells are retained in the gingival connective tissue of aged mice. Human GFs and GSCs expressed NC-related genes nestin, Snai1, Twist1, Pax3, Sox9 and FoxD3, and generated neurospheres. This was mediated via calcium- and connexin 43-dependent cell communication, which is similar to neurospheres formed by neural progenitors. Cells in the spheres showed significantly increased expression of NC-related genes, and down regulation of fibroblast-related type I collagen. Structurally, the neurospheres were polarised with nestin positive cells located on the outer layers underlined with an extracellular matrix rich in molecules typical to embryonic NC. Sphere-derived cells expressed significantly elevated levels of neural markers, and differentiated into Tau, neurofilament-M and GFAP-positive cells suggesting neural differentiation potential. Thus, human GF and GSC cultures may provide an efficient source of NC-derived cells via enrichment by floating sphere cultures.

RESUMO

OBJECTIVE: To document the occurrence of impulse control behaviours (ICBs) in patients with Parkinson's disease after 3 years of continuous deep brain stimulation (DBS) of the subthalamic nucleus (STN). METHODS: Detailed neurological and ICB assessments were performed before STN DBS and up to 3 years after implant. RESULTS: 13 out of 56 patients (23.2%) had ICBs at baseline; they took higher doses of dopamine agonists (DAA). Three years after implant 11 had fully remitted with a 60.8% reduction of DAA medication; the remaining two, who had a similar medication reduction, had only compulsive eating, having recovered from hypersexuality. Six of the 43 patients without ICBs at baseline (14%) developed transient de novo ICBs after implant; none of them had ICBs at the 3-year observation. CONCLUSIONS: ICBs were abolished in patients 3 years after STN DBS and DAA dosages were lowered. New ICBs may occur after implant and are transient in most cases. Compulsive eating may be specifically related to STN stimulation.

RESUMO

In March of 2013, new symptoms were observed in more than seven million nursery-grown sweet pepper (Capsicum annuum) plants in El Ejido, Almería (southern Spain). Symptoms included wilting without yellowing of leaves and stunting of plants. Plant crowns exhibited necrosis that advanced through the main root along with slight root rot. Xylem was not affected above or below the crown. Symptoms were thought to be caused by the well-known pepper pathogen Phytophthora capsici. However, sporodochia of Fusarium oxysporum were observed on plant crowns. Symptomatic seedlings (n = 200) were sampled and analyzed. Tissue from roots and epidermal crowns were plated on PDA, PARP, and Komada media, as well as stem discs on PDA and Komada. No Phytophthora sp. were observed and F. oxyporum was exclusively isolated from all 200 samples, from roots and crowns, but not from xylem. Pathogenicity of 60 of these F. oxysporum isolates was studied by inoculation onto sweet pepper plants (cv. del Piquillo) at the 2-true-leaf stage. Twelve plants per isolate, grown on autoclaved vermiculite, were inoculated by drenching with 20 ml of a conidial suspension (1 × 105 CFU/ml) of each isolate per plant. Each suspension was obtained by blending one PDA petri dish fully covered with one isolate. Non-inoculated plants served as control. Plants were maintained for 30 days in a growth chamber with a 14-h photoperiod (1.6 ×·104 lux) and temperatures at 23 to 26°C. The assay was conducted twice. Symptoms described above were reproduced on crown and roots of the inoculated plants with no symptoms in stem discs. No symptoms were observed on controls after 48 days. Host specificity was tested for 13 isolates to tomato (Solanum lycopersicum) cv. San Pedro, eggplant (S. melongena) cv. Alegria, cucumber (Cucumis sativus) cv. Marketmore, watermelon (Citrullus lanatus) cv. Sugar Baby, and Chinese cabbage (Brassica campestris subsp. condensa) cv. Kasumi (4). These plants were inoculated as previously described for pathogenicity tests (12 plants per species, repeated twice). None of the plants exhibited the characteristic symptoms after 60 days. Five isolates of F. oxysporum f. sp. radicis-cucumerinum and four isolates of F. o. f. sp radicis-lycopersici were also inoculated without any symptoms in any of the inoculated sweet pepper plants. Morphological identity of all isolates corresponded to F. oxysporum. The fungi were identified following the morphological keys and methodology provided by (1) and (2). Three isolates from the 60 tested were selected for molecular identification. Molecular identification was performed by sequencing partial TEF-1α gene (3). Subsequent database searches by BLASTn indicated that the resulting sequence of 659-bp had 100% identity with the corresponding gene sequence of F. oxysporum. The sequences were identical for the three isolates and were deposited on the EMBL Sequence Database (HG916993, HG916994, and HG916995). Results suggest that the pathogenic ability of the isolates varies from a vascular Fusarium wilt. F. oxysporum f. sp. capsici is a reported pathogen to sweet pepper (5), but the symptoms we have found are closer to those manifested by the formae speciales that causes root and crown rot of other plants. Consistent with the convention stablished for similar diseases we propose the name F. oxysporum f. sp. radicis-capsici f. sp. nov. References: (1) J. F. Leslie and B. A. Summerell.

RESUMO

Hip femur is extremely common in the elderly and is one of the most common reasons for admission in trauma care. The main reported causes of death after hip fracture were cardiovascular (29%), neurological (20%) and pulmonary. Large epidemiological studies have shown a relatively small decrease in mortality for 20 years despite an active approach to medical and surgical management. Yet 57% of deaths occurring within 30 days post-surgery are preventable because they are not related to a pre-existing disease. Preoperative management to optimize these patients could help to reduce morbidity and mortality and is thus a crucial issue. The anesthesia consultation is used to evaluate the perioperative risk, treat pain, manage treatment and stabilize the patient. An operative delay of more than 48hours after admission increases mortality. This period should not be prolonged by unnecessary investigations that will not change the perioperative management. The preoperative period is a key moment because it allows to choose the anesthetic technique. Even if this choice is controversial, continuous spinal anesthesia (titrated) do not modify the cardiovascular and neurological physiological balance of these precarious patients.

RESUMO

BACKGROUND: Dopamine neurotransmission plays a key role in several brain activities, including motor, cognitive, and behavioral functions. Parkinson's disease (PD) typically begins with asymmetrical motor features related to asymmetrical dopamine denervation. This study was designed to examine whether distinct cognitive, behavioral, and personality features are related to this asymmetry. METHODS: Fifty-six patients with mild PD and lateralized motor features were grouped according to dominant side of motor features and evaluated using a neuropsychological assessment focused on attention and executive functions, impulse control disorders, and personality inventory. RESULTS: There were no differences in neuropsychological functions between patients with right and left lateralized PD, but differences occurred in personality features. Patients with motor impairment predominant on the left-hand side had prevalence of hypomania and conversion profile. CONCLUSIONS: This study suggests that side dominance of dopaminergic denervation may be related to personality features in patients with PD that could influence behavioral aspects.
