Evaluation of the incorporation of an IOTA-ADNEX model in the discrimination of adnexal masses in our third-level hospital centre, taking into account the menopausal status of patients. Five years of experience / Evaluación de la incorporación del IOTA-ADNEX model en la discriminación de las masas anexiales en nuestro centro hospitalario de tercer nivel teniendo en cuenta el estado menopáusico en la predicción de malignidad. Cinco años de experiencia

Objective: The objectives were to estimate the performance of the IOTA-ADNEX model test after its incorporation into the ultrasound tests of our third-grade hospital gynecology service, as well as to assess whether its capacity of accuracy is modified when taking into account the patient's menopausal status. Methods: A cross-sectional study was conducted to clinically evaluate the diagnostic performance of the IOTA-ADNEX model test, which was performed between January 2016 and December 2021. The study included 573 women with an adnexal injury who underwent surgical excision within 180 days after ultrasound diagnosis and histological confirmation (gold standard). After the ultrasound exam, the injuries were classified using the ADNEX model. The study estimated the area under the receiver-operating-characteristics curve (AUC) of the ADNEX model for classifying between benign and malignant adnexal masses and compared the performance by menopausal state. Sensitivity and specificity were determined for different cut-off points. Results: Out of the 573 women, 183 (31.9%) had a malignant tumor. The AUC of the ADNEX model for differentiating between benign and malignant adnexal masses at the time of ultrasound examination was 0.92 and the best malignancy threshold, detected by Youden index, was 22.5%. At this cut-off, the sensitivity of the ADNEX model was 91.8% and the specificity was 76.4%. However, it varies according to menopausal status: in the group of pre-menopausal patient, sensitivity was 86.1% (95% CI, 85.4%–86.8%) and specificity was 81.3% (95% CI, 85.4%–86.8%). In the postmenopausal group, sensitivity was 96.1% (95% CI, 95.6%–96.7%) and specificity was 68.5% (95% CI, 68.1%–68.8%)...(AU)

Objetivo: Los objetivos eran estimar el rendimiento del test IOTA ADNEX model después de su incorporación en el estudio ecográfico en nuestro servicio de ginecología, en un hospital de tercer nivel, así como evaluar si su capacidad de precisión se modifica al tener en cuenta el estado menopáusico de la paciente. Método: Se llevó a cabo un estudio transversal para evaluar clínicamente el rendimiento diagnóstico del test IOTA ADNEX model, el cual se realizó entre enero de 2016 y diciembre de 2021. El estudio incluyó a 573 mujeres con una lesión anexial que se sometieron a tratamiento quirúrgico en un plazo de 180 días después del diagnóstico por ecografía y confirmación histológica (gold standard). Después de realizar la ecografía, las lesiones fueron clasificadas utilizando el modelo ADNEX. El estudio estimó el área bajo la curva (AUC) del modelo ADNEX para diferenciar entre masas anexiales benignas y malignas, y se comparó el rendimiento según el estado menopáusico. Se determinó la sensibilidad y la especificidad para diferentes puntos de corte. Resultados: De las 573 mujeres, 183 (31,9%) tenían un tumor maligno. El AUC del modelo ADNEX para diferenciar entre masas anexiales benignas y malignas en el momento del examen ecográfico fue de 0,92 y el umbral de malignidad óptimo, detectado por el índice de Youden, fue del 22,5%. Con este punto de corte, la sensibilidad (SE) del modelo ADNEX fue del 91,8% y la especificidad (SP) fue del 76,4%. Sin embargo, esto varía según el estado menopáusico: en el grupo de pacientes premenopáusicas, la sensibilidad fue del 86,1% (IC del 95%: 85,4-86,8%) y la especificidad fue del 813% (IC del 95%: 85,4-86,8%). En el grupo de pacientes posmenopáusicas, la sensibilidad fue del 96,1% (IC del 95%: 95,6-96,7%) y la especificidad fue del 68,5% (IC del 95%: 68,1-68,8%)...(AU)

Afectación ocular secundaria a la infección por Monkeypox virus / Ocular involvement secondary to Monkeypox virus infection

Presentamos el caso de un paciente varón de 37años con cuadro compatible con conjuntivitis adenovírica de 5días de evolución. Se pautaron corticoides tópicos, lubricantes y retirada de pseudomembranas. El análisis mediante PCR del exudado conjuntival resultó positivo para Monkeypox virus. Durante el seguimiento presentó úlceras corneales de evolución tórpida, por lo que precisó ingreso para instaurar tratamiento con tecovirimat. La afectación ocular por Monkeypox virus suele ser leve y autolimitada. Se han descrito casos con afectación visual severa cuando hay daño corneal, tal y como se ejemplifica en este caso. Tras el ingreso hospitalario para tratamiento sistémico, presentó una evolución favorable. (AU)

Effect of probiotic Lactiplantibacillus plantarum and chestnut flour (Castanea sativa mill) on microbiological and physicochemical characteristics of dry-cured sausages during storage.

The effect of chestnut flour (Castanea sativa Mill) on L. plantarum viability and physicochemical characteristics in a dry-cured sausage (Longaniza de Pascua) during storage is discussed. Four batches were prepared: CL with 3% chestnut flour added; CPL with 3% chestnut flour and 8.5 log CFU/g L. plantarum added; PL with 8.5 log CFU/g L. plantarum added and L, the batch control. The sausages were stored at 4 °C and 20 °C, and vacuum packed for 43 d. L. plantarum viability was affected by storage time (P < 0.001). However, higher L. plantarum counts at the final of storage were reached due to chestnut flour addition (P < 0.001). At room storage, chestnut flour caused a higher increase in TBARS values (P = 0.022). Nevertheless, all lipid oxidation treatments were in the range of accepted values at the sensory detection level. In conclusion, Longaniza de Pascua can be kept at 4 °C or 20 °C for 43 d without causing any rancidity problems.

Comparison of the osteogenic, adipogenic, chondrogenic and cementogenic differentiation potential of periodontal ligament cells cultured on different biomaterials.

It has been shown that the cellular responses such as adhesion, proliferation and differentiation are influenced by the surface properties, such as the topography or the surface energy. However, less is known about the effect of the chemical composition and type of material on the differentiation potential. The objective of the present paper is to compare the differentiation potential of periodontal ligament cells (HPLC) into adipocytes, osteoblasts, chondroblasts and cementoblasts of three type of materials (metals, ceramics and polymers) without using any biological induction media, but keeping the average roughness values within a limited range of 2.0-3.0µm. The samples were produced as discs of 14×2mm; (n=30 for each type of material). Two samples of each type were chosen; stainless-steel 316L and commercially pure titanium for the metallic samples. The polymers were polymethyl methacrylate and high-density polyethylene, and finally for the ceramics; zirconia and dental porcelain were used. The surfaces properties of the samples (wettability, chemical composition and point of zero charge, PZC) were measured in order to correlate them with the biological response. To evaluate the potential of differentiation, human periodontal ligament cells obtained from extracted teeth were used since they are a promising source for periodontal tissue regeneration. Cell proliferation was initially tested to assure non-toxic effects using a viability colorimetric assay. Finally, the differentiation pattern was evaluated using real time reverse transcription quantitative polymerase chain reaction for 5, 10 and 15days without adding any induction medium. The results indicated that the relative expression of genes related to a particular phenotype were different for each surface. However, not clear correlation between the type of material or their surface properties (morphology, chemical composition, wettability or point of zero charge) and the expression pattern could be identified. For example, bone markers were mainly expressed on cpTi and PMMA; one metallic hydrophobic and one polymeric hydrophilic sample which have similar Ra values but presented different topographical features, although both samples have in common a PZC below 7.

The effect of simulated inflammatory conditions on the surface properties of titanium and stainless steel and their importance as biomaterials.

This work compares the surface modifications induced by the immersion in solutions that simulate inflammatory conditions of pure titanium (cpTi) and medical grade stainless steel (SS). The inflammatory conditions were simulated using a mixture of Hartman solution and 50mM of hydrogen peroxide (H2O2) at pH=5.2. The samples were immersed by 7days refreshing the solution every day to keep the reactivity of the H2O2. The surface characteristics that were investigated were: elemental composition by X-ray photoelectron spectroscopy (XPS); topography by atomic force microscopy (AFM) and profilometry; wettability and surface energy by sessile drop contact angle and point of zero charge by titration. Moreover, the variations in the electrochemical response were evaluated by open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP) performed before and after the treatment using the Hartman solution as the electrolyte. The XPS results indicated that for both metallic samples, oxidation of the surface was promoted and/or the oxide layer was thicker after the immersion. The roughness and the solid-liquid surface energy were increased; the samples showed a more hydrophilic character after the treatment. However, the surface energy of the solid estimated using the Van Oss-Chaudhury-Good approach showed different trends between the cpTi and the SS surfaces; the polar component decreased for cpTi, while it increased for SS. Finally, the electrochemical results indicated that the corrosion resistance (Rcor) and the pore resistance (Rpo) significantly decreased for cpTi, while both resistances were not significantly different for the SS. This is indicative of a higher dissolution of the cpTi compared to SS and the lower Rpo means that the species are easily transported through the surface layer, which can be explained in terms of the formation of a porous TiOx layer, not observed on the SS. The cpTi surface suffered from a dissolution/oxidation process that allows its integration with the surrounding media, while the SS remained completely passive and this different response might be related to their distinguished clinical outcome.

[Injection of Lipotransplants for Wound Healing Complications after Radiotherapy]. / Injektion von Bauchfett bei radiogenen Wundheilungsstörungen.

Wound healing complications in irradiated tissues represent a major clinical challenge. Fistula or even major vessel rupture may occur. The injection of adipose tissue derived stem cells seem to be a promising therapeutical strategy. The article describes the clinical case of a patient suffering from a pharyngo-cutaneous fistula after laryngectomy and radiotherapy. The patient was successfully treated by the injection of fat tissue.

Effect of chitosan edible films added with Thymus moroderi and Thymus piperella essential oil on shelf-life of cooked cured ham.

The aim of this work was to develop chitosan edible films added with essential oils obtained from two Thymus species, Thymus moroderi (TMEO) and Thymus piperella (TPEO) to determine their application for enhancing safety (antioxidant and antibacterial properties) and shelf-life of cooked cured ham (CCH) stored at 4 °C during 21 days. Addition of TMEO and TPEO into chitosan films decreased the aerobic mesophilic bacteria (AMB) and lactic acid bacteria (LAB) counts in coated cooked cured ham samples as compared with uncoated samples. Both AMB and LAB showed the lowest counts in CCH samples coated with chitosan films added with TPEO at 2 %. In regard to lipid oxidation, the CCH samples coated with chitosan films added with TMEO or TPEO had lower degrees of lipid oxidation than uncoated control samples. Chitosan films added with TPEO at 2 % showed the lowest values. The addition of TPEO or TMEO in chitosan films used as coated in CCH improved their shelf life.

Effect of date palm coproducts and annatto extract on lipid oxidation and microbial quality in a pork liver pâté.

Dates are an interesting source of bioactive compounds, and coproducts from the date industry are of potential use in the manufacturing of meat products. In the present research, spreadable pork liver pâtés were made using fresh date coproducts (2.5% and 7.5%) as a potential functional ingredient and an ethanolic annatto extract (128 mg/kg) as colorant. The effect of these 2 ingredients on the lipid oxidation and microbial quality of the pâtés was assessed during 21 d of storage. The pâtés containing 7.5% date paste were seen to have the highest content of phenolic compounds during storage. The combination of 2.5% date paste and annatto protected pâtés against lipid oxidation throughout the 21 d of storage, thiobarbituric acid-reactive substances values being 0.47 mg MDA/kg at the end of this period, while other combinations increased oxidation compared to the control pâté. The control and those made with 2.5% date paste alone showed the highest counts of mesophilic aerobic bacteria, while the addition of annatto and/or 7.5% date paste reduced this count. The results suggest that a combination of both ingredients is necessary to reduce oxidation and microbial growth, but whereas the concentration of 2.5% is more appropriate to reduce oxidation, the combination with 7.5% date paste reduces the microbial counts. Both ingredients could have an opportunity of valorization in the meat industry for improving the quality.

Tomato and tomato byproducts. Human health benefits of lycopene and its application to meat products: a review.

During recent decades, the food industry, consumers, and regulatory authorities have developed a significant interest in functional foods because of their potential benefits for human health over and above their basic nutritional value. Tomato is the second most important vegetable crop in the world. The amount of the related wastes is estimated at up to 50,000 tons per year, representing a serious disposal problem with a consequent negative impact on the environment. Tomato byproducts contain a great variety of biologically active substances, principally lycopene, which have been demonstrated by in vitro and in vivo studies to possess antioxidant, hypolipidemic, and anticarcinogenic activities. The aim of this review is to present an overview of the functional and physiological properties of the principal bioactive compound present in tomato and tomato byproducts, lycopene, its addition to meat, and meat products.

Food ingredients as anti-obesity agents: a review.

Overweight and obesity have a major impact on global health; their prevalence has rapidly increased in all industrialized countries in the past few decades and diabetes and hypertension are their direct consequences. Pharmacotherapy provides reinforcement for obesity treatment, but should be an adjunctive support to diet, exercise, and lifestyle modification. At present, only orlistat and sibutramine have been approved by the US Food and Drug Administration for long-term use, but sibutramine was withdrawn for sale by the European Medicines Agency. The development of functional foods for the prevention and/or treatment of obesity suppose an opportunity for the food market and involve the knowledge of the mechanisms of appetite and energy expenditure as well as the metabolic sensation of satiety. Strategies for weight control management affect gut hormones as potential targets for the appetite metabolic regulation, stimulation of energy expenditure (thermogenesis), and modifications in the metabolic activity of the gut microbiota. Functional foods for obesity may also include bioactive fatty acids, phenolic compounds, soybean, plant sterols, dietary calcium, and dietary fiber. This review intends to offer an overview of the present situation of the anti-obesity agents currently used in dietary therapy as well as some functional food ingredients with potentially anti-obesity effects.

Effect of tiger nut fibre addition on the quality and safety of a dry-cured pork sausage ("Chorizo") during the dry-curing process.

There is a growing interest in the revalorization of co-products from the food industry. Co-products from tiger nuts (Cyperus esculentus) milk production are a suitable fibre source. "Chorizo" is the most popular dry-cured meat product in Spain. The aim of this work was to study the effect of the tiger nut fibre addition (0, 5, and 7.5%) on the quality (composition, physicochemical, and sensorial properties) and safety (oxidation and microbial quality) of a Spanish dry-cured sausage, during the 28days of its dry-curing process. Tiger nut fibre (TNF) addition decreased fat and increased moisture content. The addition of TNF significantly increased (p<0.05) the total dietary fibre content of "Chorizo". Lightness (L*), yellowness (b*) and redness index (a*/b*) were significantly (p<0.05) affected by the fibre content. The addition of 5% and 7.5% TNF to chorizo provided rich fibre and a healthier product. Although there were slight changes in the physicochemical properties, its quality (traditional characteristics) and its safety remained.

Substitution of saturated fat in processed meat products: a review.

The food industry is increasingly directing its efforts to produce and commercialize functional foods where the reduction or even elimination of saturated fat is an important goal. This situation arises from the concern of many institutions and individuals worldwide on the growth of non-transmissible diseases, particularly cardiovascular ones. This article presents a revision of the most important research carried out on processed meat products production and looks at the topic from two principal points of view: the nutritional and technological function of fat and the way in which it is gradually being replaced in the above-mentioned products. Many ingredients have been used to substitute fat but while the results concerning the nutritional composition of the final products are generally acceptable, the sensory aspects are not completely solved. This review emphasizes the use of plastic fats because they allow the highest fat substitution levels during its process and consumption without affecting the product behavior.

[Voice and identity in transsexuality]. / Stimme und Identität bei Transsexualität.

For the self-acceptance and social approval of transsexuals in their new identity, the voice plays a very important role. The responsibility of the phoniatrician and voice therapist is to identify in advance what type of voice change options are possible. These can either be achieved by more conservative means or through operative procedures. Whether to undergo speech therapy or perform a laryngeal surgical intervention should be discussed with the patient and determined on an individual basis.

Effect of the molecular weight and concentration of chitosan in pork model burgers.

Chitosan of high and low molecular weights was added at 0%, 0.25%, 0.5% and 1% concentrations to a burger model system. Burgers were evaluated by physicochemical analysis, cooking characteristic and storage stability. The antioxidant activity of chitosan was studied in vitro. The addition of chitosan influenced pH and color properties, in molecular weight and concentration dependent ways. Cooking properties were significantly affected by the chitosan. High molecular weight chitosan improved all cooking characteristics compared with control samples. Low molecular weight chitosan increased the shelf life of burgers, enhanced the red color and reduced total viable counts, compared with control and high molecular weight chitosan samples. The antioxidant activity of chitosan was dependent on molecular weight and concentration. The results indicate that high molecular weight chitosan (HMWC) improves all cooking characteristics and antioxidant activity while low molecular weight chitosan extends the red color and reduces total viable counts.

Spices as functional foods.

Spices and aromatic herbs have been used since antiquity as preservatives, colorants, and flavor enhancers. Spices, which have long been the basis of traditional medicine in many countries, have also been the subject of study, particularly by the chemical, pharmaceutical, and food industries, because of their potential use for improving health. Both in vitro and in vivo studies have demonstrated how these substances act as antioxidants, digestive stimulants, and hypolipidemics and show antibacterial, anti-inflammatory, antiviral, and anticancerigenic activities. These beneficial physiological effects may also have possible preventative applications in a variety of pathologies. The aim of this review is to present an overview of the potential of spices and aromatic herbs as functional foods.

[Clinical- histological correlation in patients with dry eye]. / Correlación clínico-histológica en los pacientes con ojo seco.

AIM: It is well known that there is a lack of association between symptoms and signs in patients with dry eye disease. The purpose of this study was to assess if there was any agreement between common dry eye diagnostic tests and to compare them with impression cytology. METHODS: A total of 40 patients were enrolled in this cases-controls study. The group of cases consisted of 20 patients previously diagnosed with dry eye and the controls were 20 volunteers. The examination included: the quality of life test OSDI, break up time test (BUT), fluorescein staining, Schirmer's test and finally the study of goblet and conjunctival epithelial cells with impression cytology. The Student t and U Mann-Whitney tests were used to evaluate the results, and Spearmans Rho coefficient to assess their correlation. RESULTS: Statistical differences were observed between cases and controls Group for all tests (P<0.0001). After assessing the good correlation between BUT, fluorescein staining and Schirmer's test, we studied their association with the impression cytology. The number of isolated goblet cells showed a weak association with the majority of tests, however the grade of metaplasia showed a greater association. CONCLUSION: Impression cytology is a valuable test in the diagnosis of dry eye. Although the number of goblet cells is not a sufficient diagnostic criterion, its joint assessment with the grade of metaplasia and the other dry eye tests is useful.

Effect of added citrus fibre and spice essential oils on quality characteristics and shelf-life of mortadella.

The objective of this work was to study the effect of adding orange dietary fibre (1%), rosemary essential oil (0.02%) or thyme essential oil (0.02%) and the storage conditions on the quality characteristics and the shelf-life of mortadella, a bologna-type sausage. The moisture, fat, ash content and colour coordinates lightness (L*) and yellowness (b*) were affected by the fibre content. The treatments analysed lowered the levels of residual nitrite (57.56% and 57.61%) and the extent of lipid oxidation, while analysis of the samples revealed the presence of the flavonoids, hesperidin and narirutin. No enterobacteria or psychotropic bacteria were found in any of the treatments. The treated samples stored in vacuum packaging showed the lowest aerobic and lactic acid bacteria counts. Sensorially, the most appreciated sample was the one containing orange dietary fibre and rosemary essential oil, stored in vacuum packaging. Orange dietary fibre and spice essential oils could find a use in the food industry to improve the shelf-life of meat products.

Effect of tiger nut fibre on quality characteristics of pork burger.

Horchata is a refreshing beverage obtained from tiger nut tubers that yields high amount of by-products. These by-products have a high content of fibre that allows its application in the development of dietary fibre rich foods. The utilization of increasing levels (0%-control, 5%, 10% and 15%) of tiger nut fibre (TNF), in the formulation of pork burgers was evaluated. This evaluation was based on: chemical composition, physicochemical, cooking characteristics and sensory properties of burgers. Pork burgers elaborated with TNF had higher nutritional value (higher fibre content) and better cooking characteristics (higher cooking yield, fat retention and moisture retention) than control burgers. Some of the negative changes in colour (a* decrease and b* increase) and texture (chewiness and springiness increase) parameters due to TNF addition observed in raw burgers were masked by the stronger modifications due to the cooking process. Burgers with TNF were perceived as less greasy, less juicy, more grainy and with less meaty flavour than controls; although this perception did not reduce the overall acceptability of burgers. Overall acceptability scores were slightly lower in burgers with 15% TNF, although no significant differences were detected with the scores of control, 5% and 10% TNF burgers. TNF addition to burgers is a promising and convenient application as dietary fibre of burgers was significantly increased without changes in sensory acceptance.
