RESUMO

Epigenetic alterations play a pivotal role in conditions influenced by environmental factors such as overweight and obesity. Many of these changes are tissue-specific, which entails a problem in its study since obtaining human tissue is a complex and invasive practice. While blood is widely used as a surrogate biomarker, it cannot directly extrapolate the evidence found in blood to tissue. Moreover, the intricacies of metabolic diseases add a new layer of complexity, as obesity leads to significant alterations in adipose tissue, potentially causing associated pathologies that can disrupt existing correlations seen in healthy individuals. Here, our objective was to determine which epigenetic markers exhibit correlations between blood and adipose tissue, regardless of the metabolic status. We collected paired blood and adipose tissue samples from 64 patients with morbidity obesity and non-obese and employed the MethylationEPIC 850 K array for analysis. We found that only a small fraction, specifically 4.3% (corresponding to 34,825 CpG sites), of the sites showed statistically significant correlations (R ≥ 0.6) between blood and adipose tissue. Within this subset, 5327 CpG sites exhibited a strong correlation (R ≥ 0.8) between blood and adipose tissue. Our findings suggest that the majority of epigenetic markers in peripheral blood do not reliably reflect changes occurring in visceral adipose tissues. However, it is important to note that there exists a distinct set of epigenetic markers that can indeed mirror changes in adipose tissue within blood samples. KEY MESSAGES: More than 8% of methylation sites exhibit similarity between blood and adipose tissues, regardless of BMI The correlation percentage between blood and adipose tissue is strongly influenced by gender The principal genes implicated in this correlation are related to metabolism or the immunological system.

RESUMO

PURPOSE: Cardiovascular disease (CVD) is more prevalent in men than women, but the mechanisms responsible for this are not fully understood. We aimed to evaluate differences in trimethylamine (TMA), a microbial metabolite and its oxidized form, trimethylamine N-oxide (TMAO), which is thought to promote atherosclerosis, between men and women with coronary heart disease (CHD), using as a reference a non-CVD population. MATERIALS AND METHODS: This study was carried out within the framework of the CORDIOPREV study (NCT00924937; June 19, 2009), a clinical trial which included 827 men and 175 women with CHD, with a non-CVD population of 375 individuals (270 men and 105 women) as a reference group. Plasma TMA and TMAO were measured by HPLC-MS/MS. The carotid study was ultrasonically assessed bilaterally by the quantification of intima-media thickness of both common carotid arteries (IMT-CC). RESULTS: We found higher TMAO levels and TMAO/TMA ratio in CHD men than CHD women (p=0.034 and p=0.026, respectively). No TMA sex differences were found in CHD patients. The TMA and TMAO levels and TMAO/TMA ratio were lower, and no differences between sexes were found in the non-CVD population. TMAO levels in CHD patients were consistent with higher IMT-CC and more carotid plaques (p=0.032 and p=0.037, respectively) and lower cholesterol efflux in CHD men than CHD women (p<0.001). CONCLUSIONS: Our results suggest that CHD men have augmented TMAO levels compared with CHD women, presumably as a consequence of higher rate of TMA to TMAO oxidation, which could be associated with CVD, as these sex differences are not observed in a non-CVD population.

RESUMO

Transcatheter aortic valve implantation (TAVI) is the alternative to surgical valve replacement, expanding its indications in the latest guidelines. Multimodal CT (MDCT) is essential in patient selection and detection of complications. Vascular complications are frequent, so it is important to analyse the anatomy of the vessels before the procedure. Regarding annular ruptures and ventricular perforations, the volume and distribution of calcium and the ventricular diameter play an important role. Finally, valve migration is a rare complication that can occur both during and after TAVI. Proper planning of the MDCT procedure reduces the risk of complications and gives the interventional cardiologist security both before and during the procedure.

RESUMO

Obesity is frequently accompanied by non-alcoholic fatty liver disease (NAFLD). These two diseases are associated with altered lipid metabolism, in which reverse cholesterol transport (LXRα/ABCA1/ABCG1) and leptin response (leptin receptor (Ob-Rb)/Sam68) are involved. The two pathways were evaluated in peripheral blood mononuclear cells (PBMCs) from 86 patients with morbid obesity (MO) before and six months after Roux-en-Y gastric bypass (RYGB) and 38 non-obese subjects. In the LXRα pathway, LXRα, ABCA1, and ABCG1 mRNA expressions were decreased in MO compared to non-obese subjects (p < 0.001, respectively). Ob-Rb was decreased (p < 0.001), whereas Sam68 was increased (p < 0.001) in MO. RYGB did not change mRNA gene expressions. In the MO group, the LXRα pathway (LXRα/ABCA1/ABCG1) negatively correlated with obesity-related variables (weight, body mass index, and hip), inflammation (C-reactive protein), and liver function (alanine-aminotransferase, alkaline phosphatase, and fatty liver index), and positively with serum albumin. In the Ob-R pathway, Ob-Rb and Sam68 negatively correlated with alanine-aminotransferase and positively with albumin. The alteration of LXRα and Ob-R pathways may play an important role in NAFLD development in MO. It is possible that MO patients may require more than 6 months following RYBGB to normalize gene expression related to reverse cholesterol transport or leptin responsiveness.

RESUMO

BACKGROUND: The healing process after tooth removal involves bone remodelling which implies some loss of alveolar bone volume. Among materials proposed for minimising this remodelling and preserving the bone, autologous dental tissue is a promising option, but more data are needed. In this context, we evaluated size and density changes using cone beam computed tomography in autologous dental material (ADM)-preserved sockets compared to controls, and assessed biological responses by histological analysis. METHODS: A split-mouth study was conducted including 22 patients, who underwent removal of ≥ 2 single-rooted teeth with intact sockets, assigning one socket to the experimental group which received ADM for alveolar preservation and another to the control group, which only underwent blood clot stabilisation. Cone beam computed tomography was performed postoperatively (week 0) and at weeks 8 and 16 to assess socket size and bone density. Histological analysis was carried out on trephine biopsies taken (Ø4 × 4.5 mm) from the experimental group. RESULTS: Less horizontal shrinkage was observed in the ADM group, especially at week 16 considering the group-by-time interaction for the following variables: difference in height between the lingual and buccal alveolar crests (-1.00; p < .01; 95% CI: -0.28 - -1.73), and half-widths, measured as the distance from the long axis of the missing tooth to the buccal alveolar crest at 1 mm (-0.61; p < .01; 95% CI: -0.18 - -1.04) and at 3 mm (-0.56; p < .01; 95% CI: -0.15 - -0.97) below the crest, with mean decreases of 1.07 and 2.14 mm in height difference, 0.66 and 1.32 mm in half-width at 1 mm and 0.43 and 1.02 mm in half-width at 3 mm in ADM and control groups respectively. Densitometry analysis showed higher bone densities in Hounsfield units in the ADM group considering all factors analysed regardless of time point and socket third (coronal, middle, or apical). Histologically, there were no signs of inflammation or foreign body reaction, and dentin particles were surrounded by and in close contact with bone tissue. CONCLUSION: These results add to the evidence that dentin can be used successfully as a material for alveolar socket preservation, given its desirable mechanical and biological properties, and warrant larger studies.

RESUMO

Background/objective: The Multidimensional Model of the Subjective Orgasm Experience (MMSOE) has been validated in the context of heterosexual relationships, with no evidence in the context of same-sex relationships. This study aims to examine the association of its dimensions (Affective, Intimacy, Sensory, and Rewards) with the propensity for sexual excitation, rating of sexual arousal, rating of genital sensations, and genital response. Method: Sixty-eight young adults (34 males and 34 females) who were sexually active with people of the same sex participated in a laboratory task in which they viewed content-neutral and sexually explicit gay films. Regression models were conducted to explain the dimensions of MMSOE from measures of sexual arousal. Results: In males, the rating of sexual arousal explained the Sensory dimension, while the genital response explained the Affective dimension, with sexual arousal as a state gaining more prominence. In females, however, the propensity for sexual excitation explained the Sensory dimension, with more salience of sexual arousal as a trait. Conclusions: The MMSOE is shown to be a valid theoretical framework for the study of orgasmic experience in the context of same-sex relationships, with clear implications for clinical practice.

RESUMO

STUDY QUESTION: What are the sonographic and clinical findings in women diagnosed with external and internal adenomyosis by ultrasound? SUMMARY ANSWER: Patients with external and internal adenomyosis phenotypes, diagnosed by ultrasound, present differences in sonographic features of the disease and demographic characteristics including age, parity, and association with deep endometriosis (DE) and leiomyomas. WHAT IS KNOWN ALREADY: Two different phenotypes of adenomyosis have been described based on the anatomical location of adenomyotic lesions in the myometrium, suggesting that adenomyosis affecting the inner myometrium and that affecting the external myometrial layer may have distinct origins. STUDY DESIGN, SIZE, DURATION: A cross-sectional study including 505 patients with a sonographic diagnosis of adenomyosis was performed between January 2021 and December 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women sonographically diagnosed with adenomyosis in a tertiary referral hospital that serves as a national reference center for endometriosis were included over a 2-year period. Patients were divided into two groups (internal and external adenomyosis) according to the myometrial layer affected by adenomyosis. We compared sonographic and clinical outcomes including a multivariate analysis between the two groups. MAIN RESULTS AND THE ROLE OF CHANCE: According to ultrasound findings, 353 (69.9%) patients presented with internal adenomyosis, while 152 (30.1%) presented with external adenomyosis. Women with internal adenomyosis were significantly older and less frequently nulliparous compared to those with external adenomyosis. Sonographically, internal adenomyosis appeared diffusely, it had a greater number of adenomyosis features, it presented a globular morphology of the uterus more frequently, and it coexisted with leiomyomas more frequently, compared to external adenomyosis. Conversely, the presence of translesional vascularity and associated DE were more common among the external adenomyosis group. No significant differences were found between internal and external adenomyosis groups regarding pain, heavy menstrual bleeding, spotting, or infertility. In the multivariate analysis, nulliparity, the presence of leiomyomas, and the presence of DE were independently associated with adenomyosis phenotypes (the presence of DE and nulliparity increased the risk of external adenomyosis, whereas the presence of leiomyomas was a risk factor for internal adenomyosis). Considering the impact of hormonal treatment, we found that the number of ultrasound adenomyosis criteria was significantly greater in patients without hormonal treatment. Non-treated patients more commonly presented dysmenorrhea or bleeding-associated pain and heavy menstrual bleeding than women on hormonal treatment, although there were no significant differences according to adenomyosis phenotypes. LIMITATIONS, REASONS FOR CAUTION: As the population was selected from the Endometriosis Unit of a tertiary center, there may be patient selection bias, given the high prevalence of individuals with associated endometriosis, previous endometriosis-related surgery, and/or receiving hormonal treatment. WIDER IMPLICATIONS OF THE FINDINGS: Transvaginal ultrasound is the most available and cost-effective tool for the diagnosis of adenomyosis. Adenomyosis phenotypes based on ultrasound findings may be key in achieving an accurate diagnosis and in decision-making regarding the most adequate therapeutic strategy for the management of patients with adenomyosis. Determination of the sonographic features associated with symptoms could help in the evaluation of treatment response. STUDY FUNDING/COMPETING INTEREST(S): No funding was obtained for this study and there are no conflicts of interest to declare. TRIAL REGISTRATION NUMBER: N/A.

RESUMO

A los pacientes que acuden a urgencias con síntomas inflamatorio/infecciosos a nivel cervical o con masas que pueden comprometer el tracto aerodigestivo o las estructuras vasculares, es necesario hacerles una tomografía computarizada (TC) de cuello con contraste. Su interpretación radiológica se ve dificultada por la complejidad anatómica y la interrelación fisiopatológica entre los diferentes sistemas que lo componen, en un área de estudio relativamente pequeña. Estudios recientes proponen realizar una evaluación sistemática de las estructuras cervicales, utilizando para ello un listado de verificación de 7 elementos, para identificar correctamente la patología, y detectar los hallazgos incidentales que pueden interferir en el manejo del paciente. El objetivo de este trabajo es revisar los hallazgos de la TC en la patología no traumática del cuello en urgencias siguiendo una lectura sistemática, tras la cual se pueda realizar un informe radiológico estructurado, completo y conciso.(AU)


Patients attending the emergency department (ED) with cervical inflammatory/infectious symptoms or presenting masses that may involve the aerodigestive tract or vascular structures require a contrast-enhanced computed tomography (CT) scan of the neck. Its radiological interpretation is hampered by the anatomical complexity and pathophysiological interrelationship between the different component systems in a relatively small area. Recent studies propose a systematic evaluation of the cervical structures, using a 7-item checklist, to correctly identify the pathology and detect incidental findings that may interfere with patient management. As a conclusion, the aim of this paper is to review CT findings in non-traumatic pathology of the neck in the ED, highlighting the importance of a systematic approach in its interpretation and synthesis of a structured, complete, and concise radiological report.(AU)

RESUMO

OBJECT: One of the critical steps for the success of intraventricular neuroendoscopic procedures is the entry into the third ventricle and passage of the endoscopy system through the foramen of Monro (FM). A diameter larger than that of the instrument used is considered a prerequisite for safely performing the technique, as damage to this structure can lead to alterations in the fornix and vascular structures. When the foramen diameter is narrow and there is no obstruction/stenosis, the role of foraminoplasty in reducing the risk of complications has not been adequately assessed in the literature. METHODS: A review of endoscopic procedures conducted at our center since 2018 was undertaken. Cases in which preoperative imaging indicated a FM diameter < 6 mm and foraminoplasty technique was applied were examined to determine the technical and functional success of the procedure. The technical success was determined by completing the neuroendoscopic procedure with the absence of macroscopic lesions in the various structures comprising the foramen and without complications in the follow-up imaging tests. Functional success was defined as the absence of cognitive/memory alterations during the 3-month postoperative follow-up. Additionally, a review of the various forms of foraminoplasty described in the literature is conducted. RESULTS: In our cohort, six patients were identified with a preoperative FM diameter < 6 mm without obstruction or stenosis. Foraminoplasty was planned for these cases to facilitate various intraventricular neuroendoscopic procedures. In all instances, the technique was successfully performed without causing macroscopic damage to the structures comprising the foramen. Follow-up visits included various cognitive tests to assess potential sequelae related to microscopic damage to the fornix. None of the patients exhibited anomalies. CONCLUSION: Foraminoplasty in patients with a narrow FM without signs of stenosis/obstruction is a useful technique to reduce the risk of complications during the passage of the endoscopy system through this structure, enabling the safe performance of neuroendoscopic procedures.

RESUMO

The incidence of type 2 diabetes mellitus (T2DM) is growing in Western countries. Nutritional interventions that promote high-quality dietary patterns could help reverse this trend. We aimed to evaluate whether changes in Nutrient-Rich Food Index 9.3 (NRF9.3) were related to the risk of developing T2DM in patients with coronary heart disease (CHD). The study was carried out in the context of two healthy dietary interventions (a Mediterranean and a low-fat diet). For this purpose, we evaluated all the patients in the CORDIOPREV study without T2DM at baseline. Data were obtained during the first 5 years of dietary intervention. The score was calculated using the Food Frequency Questionnaires at baseline and after 1 year of intervention. After 5 years of follow-up, 106 patients developed T2DM (incident-T2DM), while 316 subjects did not (non-T2DM). Total NRF9.3 score and changes during the first year of intervention were compared between incident-T2DM and non-T2DM. Incident-T2DM showed less improvement in NRF9.3 than non-T2DM (p = 0.010). In the multi-adjusted Cox proportional hazard study, patients with greater improvement in NRF9.3 had over 50% less risk of developing T2DM compared with the lowest tertile (HR 2.10, 95%, CI = 1.12-3.56). In conclusion, improved diet quality in terms of nutrient density after the dietary intervention was associated with a lower risk of T2DM in patients with CHD.

RESUMO

OBJECTIVE: To compare quality of life, in patients living with HIV infection with pharmaceutical care according to the CMO methodology: capacity, motivation and opportunity versus conventional follow-up. METHODS: Longitudinal, prospective, multicenter, health intervention study, conducted between October 2019 and November 2021 in 14 centers throughout Spain. Patients over 18 years of age, receiving antiretroviral treatment and attending the consultations of the participating Pharmacy Services for 1 year were included. Patients who did not have the autonomy to complete the planned questionnaires were excluded. At baseline, participating centers were randomized to continue using the same systematics of work (traditional follow-up) or to implement the CMO model using patient stratification models, goal setting in relation to pharmacotherapy, use of motivational interviewing, as well as longitudinal follow-up enabled by new technologies. The main variable was the difference in the number of dimensions positively affected in each follow-up arm at 24 weeks of follow-up according to the MOS-HIV questionnaire. In the CMO group, the interventions performed the most frequently were recorded. RESULTS: 151 patients were included. The median age was 51.35 years. A significant improvement in quality of life was found at the end of follow-up in the CMO group, reducing the number of patients with negatively affected dimensions (2/11 vs 8/11). The most frequent interventions carried out in the CMO group, according to the taxonomy, were Motivation (51,7%) and review and validation (49,4%). CONCLUSIONS: The quality of life of patients is higher in those centers that develop Pharmaceutical Care based on the CMO methodology compared to traditional follow-up.

RESUMO

BACKGROUND: Atherosclerosis is the leading underlying cause of coronary heart disease (CHD). In patients with CHD, intima-media thickness of common carotid arteries (IMT-CC) is a reliable, validated, and non-invasive marker of the progression of atherosclerosis. Dietary intervention may affect IMT-CC evolution through different pathways. There is a lack of clinical trials evaluating the effect of total dietary antioxidant content of diets on IMT-CC, especially in patients with CHD. OBJECTIVE: We evaluated the correlation between the diet's total antioxidant content and the changes in IMT-CC produced after 5 years of dietary intervention following two healthy diet models (Mediterranean diet and low-fat diet). We also evaluated whether the diet's total antioxidant content was related to the total redox capacity of the participants. METHODS: From the total participants of the CORDIOPREV study (clinical trial register NCT00924937), 805 participants completed the IMT-CC measurement and the dietary antioxidant evaluation at baseline and after 5 years of dietary intervention. IMT-CC was carried out by ultrasound and the dietary antioxidant evaluation was performed by the Dietary Antioxidant Index (DAI). Additionally, direct redox balance was evaluated in a subset of population by the ratio of reduced glutathione (GSH) to oxidized glutathione (GSSH) by colorimetric assay. RESULTS: We observed an inverse correlation between evolution of DAI and IMT-CC after 5-years of dietary intervention. The mean of the DAI index augmented in the Mediterranean Diet group, whereas it decreased in the Low-fat group. DAI was correlated to the GSH/GSSG ratio, supporting DAI as an adequate estimator of diet's antioxidant content. When looking for individual components of the DAI that were associated to the changes in IMT-CC, an inverse correlation was found for carotenoids, vitamin E, vitamin C, and zinc and the IMT-CC. CONCLUSIONS: Our study indicates that, after five years of dietary intervention, changes in DAI inversely correlate with changes in IMT-CC in patients with CHD. Overall effect of Mediterranean diet resulted in an increase of DAI, conversely to low-fat. Specific elements included in the DAI index were inversely correlated with IMT-CC.

RESUMO

How young children learn from different informants has been widely studied. However, most studies investigate how children learn verbally conveyed information. Furthermore, most studies investigate how children learn from humans. This study sought to investigate how 3-year-old children learn from, and come to trust, a competent robot versus an incompetent human when competency is established using a pointing paradigm. During an induction phase, a robot informant pointed at a toy inside a transparent box, whereas a human pointed at an empty box. During the test phase, both agents pointed at opaque boxes. We found that young children asked the robot for help to locate a hidden toy more than the human (ask questions) and correctly identified the robot to be accurate (judgment questions). However, children equally endorsed the locations pointed at by both the robot and the human (endorse questions). This suggests that 3-year-olds are sensitive to the epistemic characteristics of the informant even when its displayed social properties are minimal.

RESUMO

OBJECTIVE: In this study, we explored which postoperative opioid prescribing practices were associated with persistent opioid use among adolescents and young adults. BACKGROUND: Approximately 5% of adolescents and young adults develop postoperative new persistent opioid use. The impact of physician prescribing practices on persistent use among young patients is unknown. METHODS: We identified opioid-naïve patients aged 13 to 21 who underwent 1 of 13 procedures (2008-2016) and filled a perioperative opioid prescription using commercial insurance claims (Optum Deidentified Clinformatics Data Mart Database). Persistent use was defined as ≥ 1 opioid prescription fill 91 to 180 days after surgery. High-risk opioid prescribing included overlapping opioid prescriptions, co-prescribed benzodiazepines, high daily prescribed dosage, long-acting formulations, and multiple prescribers. Logistic regression modeled persistent use as a function of exposure to high-risk prescribing, adjusted for patient demographics, procedure, and comorbidities. RESULTS: High-risk opioid prescribing practices increased from 34.9% to 43.5% over the study period; the largest increase was in co-prescribed benzodiazepines (24.1%-33.4%). High-risk opioid prescribing was associated with persistent use (aOR 1.235 [1.12,1.36]). Receipt of prescriptions from multiple opioid prescribers was individually associated with persistent use (aOR 1.288 [1.16,1.44]). The majority of opioid prescriptions to patients with persistent use beyond the postoperative period were from nonsurgical prescribers (79.6%). CONCLUSIONS: High-risk opioid prescribing practices, particularly receiving prescriptions from multiple prescribers across specialties, were associated with a significant increase in adolescent and young adult patients' risk of persistent opioid use. Prescription drug monitoring programs may help identify young patients at risk of persistent opioid use.

RESUMO

For decades, needling interventions have been performed based on manual palpation and anatomic knowledge. The increasing use of real-time ultrasonography in clinical practice has improved the accuracy and safety of needling techniques. Although currently ultrasound-guided procedures are routinely used for patellar tendon pathology, e.g., during percutaneous electrolysis, the accuracy of these procedures is still unknown. This study used a cadaveric model to compare and evaluate both the accuracy and safety of ultrasound-guided and palpation-guided needling techniques for the patellar tendon. A total of five physical therapists performed a series of 20 needle insertion task each (n = 100), 10 insertions based on manual palpation (n = 50) and 10 insertions guided with ultrasound (n = 50) to place a needle along the interface between the patellar tendon and Hoffa's fat pad. All procedures were performed on cryopreserved knee specimens. Distance to the targeted tissue, time of the procedure, accurate rate of insertions, number of passes, and unintentional punctured structures between both applications (with and without ultrasound guiding) were compared. The results revealed higher accuracy (100% vs. 80%), a lower distance from needle to the targeted tissue (0.25 ± 0.65 vs. 2.5 ± 1.9 mm), longer surface of contact with the needle (15.5 ± 6.65 vs. 4.7 ± 7.5 mm), and a lower frequency of patellar tendon puncture (16% vs. 52%, p < 0.001) with the ultrasound-guided procedure as opposed to palpation-guided one. Nevertheless, the ultrasound-guided procedure took longer (54.8 ± 26.8 vs. 23.75 ± 15.4 s) and required more passes (2.55 ± 1.9 vs. 1.5 ± 0.95) to be conducted than the palpation-guided procedure (all, p < 0.001). According to these findings, the accuracy of invasive procedures applied on the patellar tendon is higher when conducted with ultrasound guidance than when conducted just on manual palpation or anatomical landmark. These results suggest that ultrasound could improve the clinical application of invasive procedures at the fat-patellar tendon interface. Due to the anatomical features of the targeted tissue, some procedures require this precision, so the use of ultrasound is recommended.

RESUMO

El mioma uterino representa el tumor más frecuente en la mujer de edad reproductiva, aunque solo un 25% de mujeres precisarán tratamiento debido a la presencia de síntomas. Disponemos de pocos estudios aleatorizados que hayan comparado las distintas opciones de tratamiento para el mioma uterino entre ellas; por ahora, la cirugía sigue siendo la opción que ha ofrecido mejores tasas de resolución sintomática, mejoría en calidad de vida y menor tasa de recurrencia. A pesar de la amplia difusión de la cirugía, sí que parece razonable pensar que, disminuyendo los tratamientos quirúrgicos, ya sea con terapias menos invasivas o con nuevos tratamientos médicos, se podría disminuir por un lado la morbilidad asociada a la cirugía y, por otro lado, los costes asociados. En este sentido, las técnicas ablativas para el tratamiento del mioma, la EAU, el HIFU y la radiofrecuencia, han demostrado resultados en cuanto a control sintomático y calidad de vida equiparables a la cirugía, con una baja tasa de complicaciones graves. El mayor problema sería las tasas de recurrencia y el impacto que pueden tener sobre la fertilidad futura de las pacientes. Será necesario disponer de mayor evidencia y estudios comparativos a largo plazo respecto a nuevas técnicas ablativas alternativas a los abordajes quirúrgicos.(AU)


Uterine fibroids are the most common tumours in women of reproductive age, but only 25% of women will require treatment due to the presence of symptoms. There are few randomised studies that have compared the different treatment options for uterine myoma; for the moment, surgery remains the option that offers the best rates of symptomatic resolution, improved quality of life, and a lower recurrence rate. Despite the widespread use of myoma surgery, it seems reasonable to believe that by reducing surgical treatments, either with less invasive therapies or with new medical treatments, both associated morbidity and costs would be reduced. In this sense, ablative techniques for myoma treatment, UAE, HIFU, and radiofrequency, have demonstrated results in terms of symptomatic control and quality of life comparable to surgery, with a low rate of major complications. Recurrence rates and the impact on patients’ future fertility would be the main concern. Future long-term comparative studies of ablative techniques and surgical approaches are needed.(AU)

RESUMO

PURPOSE: Goal orientation (GO) is a psychological construct which describes an individual's intrinsic motivation for learning in terms of mastery and performance goals. Mastery goals relate to the intrinsic drive to learn for the sake of learning, while performance goals are oriented toward validating one's own competence by seeking favorable judgments (Performance Approach; PAP) or avoiding negative judgments (Performance Avoid; PAV). Having a mastery GO has been shown to improve overall job satisfaction as well as optimize job performance. We therefore aimed to examine how GO changes during the transition to residency, which is a notoriously challenging period in medical education, and identify interventions that can increase mastery of GO. METHODS: The validated Goal Orientation in Surgical Trainees (GO-ST) instrument was administered to incoming surgical interns (n = 19) during orientation in a single, university-based program and again at 3 months into the internship. The perceived stress scale (PSS) was also administered at 3 months. Focus groups were used to assess resident perceptions and identify interventions at the end of the 3-month period. RESULTS: Eighteen interns (95%) completed a baseline GO-ST assessment and the 3-month follow-up, including the PSS. Mastery GO decreased from orientation to 3-month follow-up for the entire cohort, but this was not significant (3.89-3.63; p = 0.19). Preliminary interns showed a significant increase in PAV orientation after 3 months (3.28-3.67; p = 0.04) and had significantly lower mastery orientation scores at this time (4.07 vs 3.19; p = 0.02). PSS was significantly higher in preliminary interns at 3 months (18.56 vs 11.89; p = 0.04). Those who were predominantly mastery oriented had significantly lower perceived stress scores (11.64 vs 20.10; p = 0.002) compared with those that had performance goal orientations (PAP and PAV). Five interns (28%) participated in focus groups-identifying pertinent themes: 1) Perceptions of competence, 2) Training security; 3) Feedback approach, 4) Expectations of competence, and 5) Approaches to growth. CONCLUSION: Mastery GO declines during the transition to surgical residency. Maladaptive PAV orientation increases in preliminary interns due to different short-term priorities and assumptions of competence. Expectations and perceptions of intern competence by senior residents and attendings have a large impact on intern GO. Identifying interventions that optimize mastery goal orientation and minimize performance avoid orientation will potentially minimize intern stress, thereby improving both well-being and clinical performance.
