Enhancing precision in hysteroscopic surgery: The role of intraoperative ultrasound.

Hysteroscopy stands as the gold-standard approach for managing intrauterine pathology. However, in complex clinical cases, hysteroscopic evaluation alone may prove insufficient for the safest and successful patient management. Intraoperative ultrasound (IOUS) has emerged as a valuable adjunct to hysteroscopic surgery, offering real-time visualization of endometrial cavity, uterine walls and instruments within the uterine cavity, enabling precise delineation of anatomical structures, and helping to assess the extent of pathology during intricate interventions. This review aims to comprehensively assess the applications, efficacy and utility of IOUS in hysteroscopic surgery. Available evidence indicates that in hysteroscopic myomectomy, IOUS significantly reduces the risk of uterine perforation, particularly in submucosal FIGO 2 myomas, and enhances the likelihood of a single-step procedure. During hysteroscopic metroplasty, ultrasound guidance decreases the chance of incomplete uterine septum resection. In the hysteroscopic management of severe Asherman syndrome, IOUS reduces the risk of uterine perforation or false passage. For cesarean scar pregnancy (CSP), ultrasound is crucial in defining the most appropriate surgical approach and is effective in guiding the hysteroscopic treatment of endogenic CSP. The use of IOUS in hysteroscopy proves valuable in complex cases where the risk of uterine perforation or incomplete procedure is increased.

A Sex-Specific Trade-Off Between Pesticide Resistance and Tolerance to Heat-Induced Sterility in Tetranychus urticae.

Current pest management relies extensively on pesticide application worldwide, despite the frequent rise of pesticide resistance in crop pests. This is particularly worrisome because resistance is often not costly enough to be lost in populations after pesticide application, resulting in increased dependency on pesticide application. As climate warming increases, effort should be put into understanding how heat tolerance will affect the persistence of pesticide resistance in populations. To address this, we measured heat tolerance in two populations of the spider mite crop pest Tetranychus urticae that differ in the presence or absence of a target-site mutation conferring resistance to etoxazole pesticide. We found that developmental time and fertility, but not survival, were negatively affected by increasing temperatures in the susceptible population. Furthermore, we found no difference between resistant and susceptible populations in all life-history traits when both sexes developed at control temperature, nor when females developed at high temperature. Resistant heat-stressed males, in contrast, showed lower fertility than susceptible ones, indicating a sex-specific trade-off between heat tolerance and pesticide resistance. This suggests that global warming could lead to reduced pesticide resistance in natural populations. However, resistant females, being as affected by high temperature as susceptible individuals, may buffer the toll in resistant male fertility, and the shorter developmental time at high temperatures may accelerate adaptation to temperature, the pesticide or the cost thereof. Ultimately, the complex dynamic between these two factors will determine whether resistant populations can persist under climate warming.

The emerging role of Rituximab in the treatment of large granular lymphocytic leukemia associated with rheumatoid arthritis: a single center experience.

Large Granular Lymphocytic (LGL) leukemia is a rare lymphoproliferative disorder with a peculiar association with Rheumatoid Arthritis (RA). The most common feature is neutropenia and patients can have splenomegaly, resembling Felty's Syndrome. These diseases have similar clinical and laboratory abnormalities, but the diagnosis of T-cell LGL (T-LGL) leukemia requires evidence of clonality. Even though T-LGL leukemia is indolent in most cases, inadequate treatment when it is indicated can lead to significant morbidity and mortality, mainly associated with recurrent infections. We present two clinical cases that emphasize the emerging role of Rituximab as an effective therapeutic option in patients with T-LGL and RA.

Preconception counseling impact in pregnancy outcomes in patients with spondyloarthritis.

INTRODUCTION: Spondyloarthritis (SpA) is a group of chronic inflammatory diseases, often affecting women in reproductive age. These diseases can have a significant impact on the reproductive health of women. Preconception counseling and medication adjustments have shown to reduce flares and improve pregnancy outcomes in women with rheumatoid arthritis. However, in women with SpA data of the impact of preconception counselling on pregnancy outcomes is scarce. The aim of this study is to evaluate that. METHODS: In this retrospective multicentric study, data was collected from medical records of women who gave birth from 2020 to 2022. The study included 45 pregnancies, which were divided into two categories whether they received preconception consultation or not. Data was collected on patient characteristics, disease duration, medications used, and preconception counselling. Outcomes were divided into two groups: maternal and fetal outcomes. RESULTS: 30 out of 45 pregnancies (66.67%) had received preconception counselling, having a significantly lower percentage of flares occurring postpartum compared to the non-counselling group (36.6% vs 6.4%, p=0.031) and lower percentage of contraindicated medication during pregnancy (20.0 vs 0.0%, p=0.011). CONCLUSION: Preconception counselling in women with SpA can increase the likelihood of medication adjustments before pregnancy and decrease the occurrence of flares postpartum. These findings suggest that preconception counselling should be implemented in the management of pregnant women with SpA to improve pregnancy outcomes. Further studies are needed to confirm the effectiveness of preconception counselling and to determine the optimal approach.

Knowledge in Inflammatory Bowel Disease: Translation to Portuguese, Validation, and Clinical Application of the IBD-KNOW Questionnaire.

Background/Aims: Inflammatory bowel disease (IBD)-related knowledge empowers patients, providing the development of adaptative coping strategies. Recently, a more comprehensive questionnaire for evaluating IBD-related knowledge was developed, the IBD-KNOW. The main aim of our study was to translate to Portuguese and validate the IBD-KNOW questionnaire. We also explored the predictors of high scores of disease-related knowledge and the effect of knowledge on health-related quality of life (HRQoL) and therapeutic adherence. Methods: This is an observational, unicentric, and cross-sectional study. We translated and adapted the original English version of the IBD-KNOW questionnaire into Portuguese. Afterwards, IBD patients in the outpatient clinics were invited to fill out a multimodal form including the Portuguese version of IBD-KNOW, a visual analogue scale (VAS) of self-perceived knowledge, the Portuguese version of Short IBD Questionnaire (SIBDQ) and the Portuguese version of Morisky Adherence Scale 8-item (MMAS-8). Demographic and disease characteristics were collected. We assessed validity (through discriminate validity among non-IBD volunteers and correlation between IBD-KNOW and VAS) and reliability (through internal consistency, test-retest, and intraclass correlation). Statistical analysis was performed using SPSS version 25.0. Results: The mean IBD-KNOW score was significantly different among non-IBD validation group (doctors: 23, nurses: 18, and non-medical volunteers: 12, p < 0.001). IBD-KNOW showed a high internal consistency (Cronbach's α 0.78) and intraclass correlation (0.90). As expected, the IBD-KNOW score was positively correlated with VAS for self-perceived knowledge (r = 0.45, p < 0.001). One hundred and one patients with IBD (54 with ulcerative colitis and 47 with Crohn's disease) completed the questionnaire at baseline. Multivariate analyses showed that a high IBD-KNOW score was associated with longer disease duration (OR: 2.59 [CI 1.11-5.74]; p = 0.04), previous hospitalization (OR: 3.63 [CI 1.301-9.96]; p = 0.01), current biologic treatment (OR: 3.37 [CI 1.31-8.65]; p = 0.02), and higher educational level (OR: 4.66 [CI 1.74-10.21]; p = 0.02). Moreover, there was no significant correlation between overall IBD-KNOW and SIBDQ, nor between IBD treatment adherence (MMAS-8 = 8) and a higher mean IBD-KNOW score (p = 0.552). Conclusion: The Portuguese version of IBD-KNOW is a simple, valid, and reliable tool for assessing IBD-related knowledge. Longer disease duration, hospitalization, use of biologics, and higher educational level are associated with higher levels of knowledge. Higher patient knowledge was not associated with higher HRQoL and adherence to therapy.

Introdução/objetivos: O conhecimento relacionado com a Doença Inflamatória Intestinal (DII) visa capacitar os doentes, proporcionando o desenvolvimento de estratégias adaptativas de coping. Recentemente, foi desenvolvido um questionário mais abrangente para avaliar os conhecimentos relacionados com a DII, o IBD-KNOW. O principal objetivo do nosso estudo foi traduzir para português e validar o questionário IBD-KNOW. Também explorámos os preditores de um elevado nível de conhecimento relacionado com a DII e avaliámos o impacto do conhecimento na qualidade de vida associada a cuidados de saúde (QVACS) e na adesão terapêutica. Métodos: Este é um estudo observacional, unicêntrico e transversal. Traduzimos e adaptámos para português a versão original inglesa do questionário IBD-KNOW. Posteriormente, os doentes com DII de ambulatório foram convidados a preencher um questionário multimodal que incluía, a versão portuguesa do IBD-KNOW, uma escala visual analógica (EVA) de autoperceção do conhecimento, a versão portuguesa do Short IBD Questionnaire (SIBDQ) e a versão portuguesa do Morisky Adherence Scale 8-item (MMAS-8). Foram colhidos dados referentes a aspetos demográficos e da doença. Avaliámos a validade (através da validade discriminatória entre voluntários sem DII e da correlação entre IBD-KNOW e a EVA) e a fiabilidade (através da consistência interna, do teste-reteste e da correlação intraclasse). A análise estatística foi realizada utilizando a versão 25.0 do SPSS. Resultados: A pontuação média do IBD-KNOW foi significativamente diferente entre os voluntários não-DII (médicos: 23, enfermeiros: 18 e voluntários não-médicos: 12, p < 0,001). O IBD-KNOW mostrou uma elevada consistência interna (Cronbach's α 0,78) e uma correlação intraclasse (0,90). Como esperado, a pontuação IBD-KNOW correlacionou-se positivamente com a EVA de autoperceção do conhecimento (r=0,45, p < 0,001). Cento e um doentes com DII (54 com colite ulcerosa e 47 com doença de Crohn) preencheram o questionário. A análise multivariada mostrou valores médios de IBD-KNOW superiores em indivíduos com doença de longa duração (OR: 2,59; [IC 1,11-5,74] p=0,04), hospitalização prévia (OR 3,63 [IC 1,301-9,96]; p=0,01), sob tratamento biológico atual (OR 3,37 [1,31-8,65]; p=0,02) e com nível educacional superior (OR 4,66 [IC 1,74-10,21]; p=0,02). Além disso, não houve correlação significativa entre IBD-KNOW e SIBDQ, nem entre a adesão ao tratamento IBD (MMAS-8=8) e um IBD-KNOW acima da média (p=0,552). Conclusão: A versão portuguesa do IBD-KNOW é uma ferramenta simples, válida e fiável para avaliar os conhecimentos relacionados com a DII. Uma maior duração da doença, hospitalização, utilização de biológicos e um nível de educação mais elevado estão associados a níveis de conhecimento mais elevados. Na nossa coorte, níveis superiores de conhecimento não se associaram a melhor qualidade de vida nem a maior adesão à terapêutica.

Dietary content and combined training, but not daily physical activity, are associated with 6-month bone mineral changes in adolescents with obesity: A Secondary analysis of the PAC-MAnO trial.

PURPOSE: The present study aimed to explore the influence of diet and physical activity (PA) changes on bone mineral content (BMC) and density (BMD) alterations in adolescents with obesity undergoing a weight loss program. METHODS: Six-month longitudinal data from 71 adolescents (aged 15.1 [± 1.6] years; 57.7% girls) with a BMI z-score of 3.03 (± 0.78), previously recruited for the PAC-MAnO trial, were analyzed using Generalized Estimation Equations for over time changes and linear regressions with BMC, BMD and BMD z-score as dependent variables, adjusting for confounders (including type of exercise- aerobic vs. combined). RESULTS: Adjusting for confounders, changes in carbohydrate (CH) and protein content showed to positively and negatively predict BMD z-score variance, respectively (ß = 0.44, 95%CI: 0.01, 0.04, p < .001); ß = -0.57, 95%CI: -0.06, -0.03, p < .001), yet no associations were found between PA and bone-related parameters. Combined exercise showed better results on BMC compared to aerobic exercise (ß = 0.09, 95%CI: 0.05 to 0.13, p < .001). CONCLUSIONS: Increased CH content, instead of protein, may be associated with BMD improvements in adolescents with obesity. Type of exercise may moderate the impact of PA on bone health. TRIAL REGISTRATION: Clinicaltrials.gov NCT02941770. What is Known • Adolescents with obesity may be at a higher risk of osteopenia/osteoporosis • Obesity and inadequate diet and physical activity (PA) may have an adverse effect on bone metabolism What is New • Improvements in adiposity and muscle mass and increased diet carbohydrate content are associated with bone mineral density (BMD) improvements • Type of exercise (i.e., combined training vs. aerobic) may moderate the impact of PA on BMD, and calcium intake may mediate this impact.

O armário: Fruiting phenology data for 4,462 plant taxa in Portugal (1926-2013).

Species phenology - the timing of key life events - is being altered by ongoing climate changes with yet underappreciated consequences for ecosystem stability. While flowering is generally occurring earlier, we know much less about other key processes such as the time of fruit ripening, largely due to the lack of comprehensive long-term datasets. Here we provide information on the exact date and site where seeds of 4,462 taxa were collected for the Index Seminum (seed exchange catalogue) of the Botanic Garden of the University of Coimbra, between 1926 and 2013. Seeds were collected from spontaneous and cultivated individuals across Portugal, including both native and introduced taxa. The database consists of 127,747 curated records with information on the species, or infraspecific taxa (including authority), and the day and site where seeds were collected. All records are georeferenced and provided with a confidence interval for the collection site. Taxonomy was first curated manually by in-house botanists and then harmonized according to the GBIF backbone taxonomy.

Evaluation of data collection bias of third molar stages of mineralisation for age estimation in the living.

Age assessment of the living is a fundamental procedure in the process of human identification, in order to guarantee fair treatment of individuals, which has ethical, civil, legal, and medical repercussions. The careful selection of the appropriate methods requires evaluation of several parameters: accuracy, precision of the method, as well as its reproducibility. The approach proposed by Mincer et al. adapted from Demirjian et al. exploring third molar mineralisation, is one of the most frequently considered for age estimation of the living. Thus, this work aims to assess potential bias in the data collection when applying the classification stages for dental mineralisation adapted by Mincer et al. A total of 102 orthopantomographs, of clinical origin, belonging to individuals aged between 12 and 25 years ([Formula: see text] = 20.12 years, SD = 3.49 years; 65 females, 37 males, all of Portuguese nationality) were included and a retrospective analysis performed by five observers with different levels of experience (high, average, and basic). The performance and agreement between five observers were evaluated using Weighted Cohen's Kappa and the Intraclass Correlation Coefficient. To access the influence of impaction on third molar classification, variables were tested using ordinal logistic regression Generalised Linear Model. It was observed that there were variations in the number of teeth identified among the observers, but the agreement levels ranged from moderate to substantial (0.4-0.8). Upon closer examination of the results, it was observed that although there were discernible differences between highly experienced observers and those with less experience, the gap was not as significant as initially hypothesised, and a greater disparity between the classifications of the upper (0.24-0.49) and lower third molars (>0.55) was observed. When bone superimposition is present, the classification process is not significantly influenced; however, variation in teeth angulation affects the assessment. The results suggest that with an efficient preparation, the level of experience as a factor can be overcome. Mincer and colleague's classification system can be replicated with ease and consistency, even though the classification of upper and lower third molars presents distinct challenges.

Colorectal cancer screening: A review of current knowledge and progress in research.

Colorectal cancer (CRC) is one of the most prevalent malignancies worldwide, being the third most commonly diagnosed malignancy and the second leading cause of cancer-related deaths globally. Despite the progress in screening, early diagnosis, and treatment, approximately 20%-25% of CRC patients still present with metastatic disease at the time of their initial diagnosis. Furthermore, the burden of disease is still expected to increase, especially in individuals younger than 50 years old, among whom early-onset CRC incidence has been increasing. Screening and early detection are pivotal to improve CRC-related outcomes. It is well established that CRC screening not only reduces incidence, but also decreases deaths from CRC. Diverse screening strategies have proven effective in decreasing both CRC incidence and mortality, though variations in efficacy have been reported across the literature. However, uncertainties persist regarding the optimal screening method, age intervals and periodicity. Moreover, adherence to CRC screening remains globally low. In recent years, emerging technologies, notably artificial intelligence, and non-invasive biomarkers, have been developed to overcome these barriers. However, controversy exists over the actual impact of some of the new discoveries on CRC-related outcomes and how to effectively integrate them into daily practice. In this review, we aim to cover the current evidence surrounding CRC screening. We will further critically assess novel approaches under investigation, in an effort to differentiate promising innovations from mere novelties.

Anti-TIF1γ-Dermatomyositis and Sjögren's Syndrome As the Inaugural Presentation for Rectal Cancer.

Dermatomyositis (DM) is an inflammatory myopathy often paraneoplastic in nature. Patients have characteristic cutaneous findings and possible muscle involvement. In the latter, muscle enzymes are elevated, and the electromyogram shows varied changes. Muscle or skin biopsy and myositis-specific antibodies confirm the diagnosis. Here, we report the case of an 86-year-old woman with cutaneous lesions, proximal weakness, and sicca symptoms. Muscle enzymes and electromyogram were normal. Antinuclear antibodies were elevated, and anti-TIF1γ and anti-Ro52 antibodies were positive. Muscle biopsy was compatible with the diagnosis of DM, and salivary gland biopsy confirmed Sjögren's syndrome. Malignancy investigation identified a rectal cancer, which was resected. This case illustrates a rare form of cancer presentation - anti-TIF1γ DM with normal muscle enzymes and electromyogram and concomitant secondary Sjögren's syndrome. Malignancy screening and multidisciplinary management were crucial to a successful approach.

Systemic disease presenting as cardiac tamponade: a case report.

Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by multisystem inflammation and is a common cause of pericarditis and pericardial effusion, but significant pericardial effusion and cardiac tamponade are rare and even rarer as the first manifestation. Case summary: We report the case of a young male who presented with fever, recurrent pericarditis, and polyserositis with pericardial and bilateral pleural effusion. On examination, he was haemodynamically unstable and the pericardial effusion had considerable dimensions and an urgent pericardiocentesis was performed. Antinuclear antibody with a speckled pattern was positive, complement C4 levels were low, and the remaining autoimmunity and infectious study was unremarkable. Considering the European League Against Rheumatism/American College of Rheumatology classification criteria for SLE, a score of 11 points was obtained, confirming the diagnosis of SLE. Discussion: This case report illustrates a rare form of presentation of SLE, in which the first manifestation was pericarditis with polyserositis and cardiac tamponade.

Home Ultrasound: A Contemporary and Valuable Tool for Palliative Medicine.

This narrative review explores the application of point-of-care ultrasound (POCUS) in palliative care and its feasibility in home care settings. POCUS has the potential to streamline diagnostic strategies without patient transfer to the hospital, expedite timely symptomatic relief, and reduce complications from specific palliative interventions. The advent of handheld ultrasound devices has made it an attractive diagnostic and interventional adjunct in acute palliative care. POCUS has gained widespread acceptance as part of routine care in emergency medicine and intensive care, guiding certain procedures and increasing their safety. The modernization and miniaturization of ultrasound equipment have made ultra-portable devices available, allowing for better-quality images at affordable prices. Handheld devices have the potential to revolutionize everyday clinical practice in home-based palliative care, contributing to important bedside clinical decisions. Palliative care patients often require diagnostic examinations in the last months of their lives, with CT being the most frequently performed imaging procedure. However, CT imaging is associated with high costs and burdens, leading to increased suffering and impaired quality of life. Clinical ultrasound, a dialogic imaging modality, offers a safer and more efficient approach to palliative care. POCUS applications, which are cost-effective, non-invasive, and well-tolerated, can be used to improve patient satisfaction and diagnostic understanding. POCUS is a valuable tool in palliative care, improving diagnostic accuracy and reducing the time to diagnosis for various pathologies. It is a standard of care for many procedures and improves patient safety. However, there are limitations to POCUS in palliative care, such as operator-dependent examination variability and limited availability of trained professionals. To overcome these limitations, palliative care physicians should receive mandatory training in POCUS, which can be incorporated into the core curriculum. Additionally, ultrasound teleconsulting can assist less experienced examiners in real-time examinations. The literature on POCUS in palliative care is limited, but research on patient-oriented outcomes is crucial. POCUS should be considered a supplement to good clinical reasoning and regulated radiological evaluations.

Associations between motivation and different aspects of physical exercise in individuals who maintained weight loss / Associações entre a motivação e diferentes aspectos do exercício físico em indivíduos que mantiveram a perda de massa corporal

The objective of this study was to analyze the association between motivation and various aspects of physical exercise in individuals who maintained weight loss, and to explore the role of gender. The sample consisted of 253 participants, and their sociodemographic characteristics, body composi-tion, physical exercise, and general and specific motivation for exercise were assessed using validated instruments. The t-test was used to compare various variables between participants. Pearson's cor-relation coefficient was used to analyze the association between motivational variables and different aspects of physical exercise. Motivational variables were divided into tertiles, and the means of vari-ous aspects of physical exercise were compared between tertiles using one-way ANOVA. Differences between genders were observed in terms of intensity, duration, energy expenditure, and most motiva-tional variables, favoring males. Positive associations were identified between motivational variables related to exercise, specifically intrinsic motivation and more autonomous regulations, and different aspects of physical exercise in the total sample and among females (p < 0.05). In individuals who successfully maintained weight loss, particularly women, more autonomous motivations for exercise were associated with greater physical exercise. These findings are significant for weight loss and health promotion programs, indicating that autonomous motivation may be a factor in successful weight maintenance.

O objetivo deste estudo foi analisar a associação entre a motivação e vários aspectos da prática de exercício físico (EF) em indivíduos que mantiveram a perda de massa corporal, e explorar o papel do gênero. A amostra foi constituída por 253 participantes, foram avaliadas as suas características sociodemográficas, a composição corporal, o EF, a motivação geral e específica para o exercício, com instrumentos validados. Utilizou-se o teste t-de student de independência para comparar as diversas variáveis entre os participantes. Para analisar a associação entre as variáveis motivacionais e os diferentes aspectos do EF, utilizou-se o coeficiente de correlação de Pearson. Foram ainda criados tercis para as variáveis motivacionais e posteriormente comparadas as médias dos vários aspectos do EF entre tercis, através do teste one-way ANOVA. Observaram-se diferenças entre gêneros no que respeita à intensidade, duração e dispêndio energético e na maioria das variáveis motivacionais, favorecendo o gênero masculino. Identificaram-se associações positivas entre as variáveis motivacionais relacionadas com o exercício, nomeadamente a motivação intrínseca e as regulações de ordem mais autônoma, e os diferentes aspectos do EF, na amostra total e no gênero feminino (p < 0,05). Em indivíduos com sucesso na manutenção da perda de massa corporal, particularmente nas mulheres, motivações mais autônomas para o exercício associaram-se a maior prática de EF. Essas conclusões são significativas para programas de perda de massa corporal e promoção de saúde, indicando que a motivação autônoma pode ser um fator de sucesso na manutenção da massa corporal.

Cervical Squamous Cell Carcinoma Diagnosis by FTIR Microspectroscopy.

Cervical cancer was considered the fourth most common cancer worldwide in 2020. In order to reduce mortality, an early diagnosis of the tumor is required. Currently, this type of cancer occurs mostly in developing countries due to the lack of vaccination and screening against the Human Papillomavirus. Thus, there is an urgent clinical need for new methods aiming at a reliable screening and an early diagnosis of precancerous and cancerous cervical lesions. Vibrational spectroscopy has provided very good results regarding the diagnosis of various tumors, particularly using Fourier transform infrared microspectroscopy, which has proved to be a promising complement to the currently used histopathological methods of cancer diagnosis. This spectroscopic technique was applied to the analysis of cryopreserved human cervical tissue samples, both squamous cell carcinoma (SCC) and non-cancer samples. A dedicated Support Vector Machine classification model was constructed in order to categorize the samples into either normal or malignant and was subsequently validated by cross-validation, with an accuracy higher than 90%.

Acute Pyelonephritis and an Incidental Diagnosis.

Gastrointestinal stromal tumors (GISTs) arise from the gastrointestinal tract. In rare cases, extra-gastrointestinal stromal tumors (EGISTs) occur in the omentum, mesentery, et cetera. They are mostly asymptomatic or have unspecific symptoms. Risk stratification classification systems are based on tumor size, mitotic rate, location, and perforation. The gold standard for diagnosis is a computed tomography (CT) scan. Ultrasound/CT-guided percutaneous biopsy allows histopathology and immunochemistry results (most stain positive for CD117 (c-KIT), CD34, and/or DOG1). Mutational analysis (most are in proto-oncogene c-KIT and platelet-derived growth factor receptor A (PDGFRA)) determines appropriate therapy. Surgical resection is the gold standard of treatment, with adjuvant and neoadjuvant molecular-targeted therapies depending on recurrence risk and mutations. This report describes a rare case of GIST (omentum EGIST) with a rare presentation (acute pyelonephritis) in a 67-year-old woman. Abdominal examination showed tenderness and a positive Murphy sign on the left side. Blood analysis presented microcytic hypochromic anemia, aggravated renal function, leukocytosis, and increased C-reactive protein. Abdominal CT revealed a heterogeneous abdominal mass, and a CT-guided biopsy showed epithelioid cells positive for CD117 and DOG1, which is compatible with a GIST. The patient underwent surgery that determined the GIST's origin from the greater omentum. Histology revealed an epithelioid GIST with large dimensions and a high histologic grade. Genetic testing detected a variant in the PDGFRA gene. With a high risk of progression, the patient received a three-year course of imatinib.

Heart rate score in remote monitoring: An additional tool for predicting outcomes in heart failure with reduced ejection fraction.

BACKGROUND: Heart rate score (HRS) ≥ 70% has been associated with arrhythmic events and mortality but these studies were not specific for heart failure (HF) patients. We hypothesized that HRS ≥ 70% obtained from remote monitoring (RM) is associated with HF hospitalizations and arrhythmic events in HF with reduced ejection fraction (HFrEF). METHODS: HRS was calculated from RM in patients with HFrEF and ICD or CRT-D. Two groups were defined: HRS ≥ 70% (G1, n = 55) and HRS < 70% (G2, n = 48) RESULTS: A total of 103 patients were included (64.4 ± 13.04 years, 69.9% male, mean left ventricular ejection fraction (LVEF) 33.62 ± 11.97% and FUP 61.7 ± 38.87 months). The device was CRT-D in 59.2% and ICD in 40.8% and the majority (90.3%) had the device implanted in primary prevention. G1 patients were more frequently male (p = .017) and had more coronary disease (p = .035). HRS ≥70% was an independent predictor for unplanned HF hospitalizations (OR: 1.905 (95% CI: 1.328-3.649), p < .001)). The indication for device implantation (primary vs. secondary prevention), type of device, NYHA class, age, gender and LVEF were not independent predictors of the outcome. VF (4.9 ± 20.0 G1 vs. 1.1 ± 5.47 G2, p = .046) and VT episodes were more prevalent in G1 (3.1 ± 8.93 G1 vs. 0.3 ± 1.59 G2, p = .026), as well as appropriate device shocks (4.3 ± 12.06 G1 vs. 0.3 ± 1.49 G2, p = .023). There was no difference in inappropriate shocks or mortality outcomes between groups. CONCLUSION: HRS ≥70% obtained from RM was an independent predictor of HF hospitalizations and was associated with arrhythmic events with VT and VF episodes and appropriate device shocks in HFrEF patients.
