Leveraging the Sensitivity of Plants with Deep Learning to Recognize Human Emotions.

Recent advances in artificial intelligence combined with behavioral sciences have led to the development of cutting-edge tools for recognizing human emotions based on text, video, audio, and physiological data. However, these data sources are expensive, intrusive, and regulated, unlike plants, which have been shown to be sensitive to human steps and sounds. A methodology to use plants as human emotion detectors is proposed. Electrical signals from plants were tracked and labeled based on video data. The labeled data were then used for classification., and the MLP, biLSTM, MFCC-CNN, MFCC-ResNet, Random Forest, 1-Dimensional CNN, and biLSTM (without windowing) models were set using a grid search algorithm with cross-validation. Finally, the best-parameterized models were trained and used on the test set for classification. The performance of this methodology was measured via a case study with 54 participants who were watching an emotionally charged video; as ground truth, their facial emotions were simultaneously measured using facial emotion analysis. The Random Forest model shows the best performance, particularly in recognizing high-arousal emotions, achieving an overall weighted accuracy of 55.2% and demonstrating high weighted recall in emotions such as fear (61.0%) and happiness (60.4%). The MFCC-ResNet model offers decently balanced results, with AccuracyMFCC-ResNet=0.318 and RecallMFCC-ResNet=0.324. Regarding the MFCC-ResNet model, fear and anger were recognized with 75% and 50% recall, respectively. Thus, using plants as an emotion recognition tool seems worth investigating, addressing both cost and privacy concerns.

Effect of carboplatin when administered after dacarbazine failure: Clinical benefit of sequential therapy.

Dacarbazine chemotherapy has been the mainstay of melanoma treatment for >30 years. In the early 2000s, carboplatin (with or without other agents, such as paclitaxel) was the most commonly used second-line therapy in the UK. The aim of the present study was to report a significant response rate to second-line carboplatin in patients from three UK institutions who had been previously treated and failed to respond to dacarbazine, and investigate whether sequential therapy may be more effective compared with combination therapy. A total of 104 patients were identified, the majority of whom were treated with carboplatin (area under the curve 5-6) every 3 weeks for a maximum of 6 cycles. A total of 102 patients were evaluable for response, among whom 11 patients had an objective response (1 complete response and 10 partial responses) and 15 had stable disease, giving an overall response rate of 11% and disease control rate of 26%. The median progression-free survival was 1.8 months (range, 0.2-36+ months) and the median overall survival was 4.6 months (range, 0.2-36+ months). Surprisingly, the majority of the patients who benefited from second-line carboplatin therapy were those with visceral metastases, the survival of whom would not be expected to exceed 6 months after first-line treatment.

Maximal-Effort Cytoreductive Surgery for Ovarian Cancer Patients with a High Tumor Burden: Variations in Practice and Impact on Outcome.

BACKGROUND: This study aimed to compare the outcomes of two distinct patient populations treated within two neighboring UK cancer centers (A and B) for advanced epithelial ovarian cancer (EOC). METHODS: A retrospective analysis of all new stages 3 and 4 EOC patients treated between January 2013 and December 2014 was performed. The Mayo Clinic surgical complexity score (SCS) was applied. Cox regression analysis identified the impact of treatment methods on survival. RESULTS: The study identified 249 patients (127 at center A and 122 in centre B) without significant differences in International Federation of Gynecology and Obstetrics (FIGO) stage (FIGO 4, 29.7% at centers A and B), Eastern Cooperative Oncology Group (ECOG) performance status (ECOG < 2, 89.9% at centers A and B), or histology (serous type in 84.1% at centers A and B). The patients at center A were more likely to undergo surgery (87% vs 59.8%; p < 0.001). The types of chemotherapy and the patients receiving palliative treatment alone were equivalent between the two centers (3.6%). The median SCS was significantly higher at center A (9 vs 2; p < 0.001) with greater tumor burden (9 vs 6 abdominal fields involved; p < 0.001), longer median operation times (285 vs 155 min; p < 0.001), and longer hospital stays (9 vs 6 days; p < 0.001), but surgical morbidity and mortality were equivalent. The independent predictors of reduced overall survival (OS) were non-serous histology (hazard ratio [HR], 1.6; 95% confidence interval [CI] 1.04-2.61), ECOG higher than 2 (HR, 1.9; 95% CI 1.15-3.13), and palliation alone (HR, 3.43; 95% CI 1.51-7.81). Cytoreduction, of any timing, had an independent protective impact on OS compared with chemotherapy alone (HR, 0.31 for interval surgery and 0.39 for primary surgery), even after adjustment for other prognostic factors. CONCLUSIONS: Incorporating surgery into the initial EOC management, even for those patients with a greater tumor burden and more disseminated disease, may require more complex procedures and more resources in terms of theater time and hospital stay, but seems to be associated with a significant prolongation of the patients overall survival compared with chemotherapy alone.

Surgical Reconstruction for Talocalcaneal Coalitions With Severe Hindfoot Valgus Deformity.

INTRODUCTION: Coalition resection can restore motion, and improve pain in patients with talocalcaneal coalitions (TCCs) and an aligned foot. However, there is some debate regarding appropriate treatment of patients with associated valgus deformity. The purpose of this study was to present the outcomes and complications following surgical reconstruction, with or without coalition resection, in a series of patients with TCC and severe hindfoot valgus. METHODS: Thirteen consecutive patients (14 feet) were evaluated. Eleven patients were male. Mean age was 14 years. Mean follow-up was 43.8 months. Seven patients (8 feet) underwent simultaneous resection of the coalition and reconstruction, and 6 patients (6 feet) isolated reconstruction. The talar-first metatarsal angle, the talar-horizontal angle, and calcaneal pitch were measured preoperatively and postoperatively. Clinical evaluation was made according to the American Orthopaedic Foot and Ankle Society ankle-hindfoot score. RESULTS: All radiographic values improved significantly and were within the normal ranges postoperatively. The average American Orthopaedic Foot and Ankle Society ankle-hindfoot score had improved from 45 to 98 points (P<0.001) in the group of simultaneous resection and reconstruction, and from 60 to 92.3 points (P=0.002) in the group of isolated reconstruction. All patients were asymptomatic at the last follow-up and were satisfied with the procedure. DISCUSSION: Surgical reconstruction with or without coalition resection can achieve significant functional and radiographic improvements, and symptoms relief in selected patients with TCCs and severe valgus deformity. LEVEL OF EVIDENCE: Level IV-therapeutic study.

Electronic Devices That Identify Individuals with Fever in Crowded Places: A Prototype.

Most epidemiological surveillance systems for severe infections with epidemic potential are based on accumulated symptomatic cases in defined geographical areas. Eventually, all cases have to be clinically verified to confirm an outbreak. These patients will present high fever at the early stages of the disease. Here, we introduce a non-invasive low-cost electronic device (bracelet) that measures and reports 24/7, year-round information on the temperature, geographical location, and identification of the subject using the device. The data receiver can be installed in a tower (ground) or a drone (air) in densely populated or remote areas. The prototype was made with low-cost electronic components, and it was tested indoors and outdoors. The prototype shows efficient ground and air connectivity. This electronic device will allow health professionals to monitor the prevalence of fever in a geographical area and to reduce the time span between the presentation of the first cases of a potential outbreak and their medical evaluation by giving an early warning. Field tests of the device, programs, and technical diagrams of the prototype are available as Supplementary Materials.

Real Time Monitoring of Children, and Adults with Mental Disabilities Using a Low-Cost Non-Invasive Electronic Device.

There are a growing number of small children-as well as adults-with mental disabilities (including elderly citizens with Alzheimer's disease or other forms of age-related dementia) that are getting lost in rural and urban areas for various reasons. Establishing their location within the first 72 h is crucial because lost people are exposed to all kinds of adverse conditions and in the case of the elderly, this is further aggravated if prescribed medication is needed. Herein we describe a non-invasive, low-cost electronic device that operates constantly, keeping track of time, the geographical location and the identification of the subject using it. The prototype was made using commercial low-cost electronic components. This electronic device shows high connectivity in open and closed areas and identifies the geographical location of a lost subject. We freely provide the software and technical diagrams of the prototypes.

La condromatosis sinovial es una entidad patológica poco frecuente donde se desarrollan cuerpos de aspectos cartilaginosos a partir de la membrana sinovial de articulaciones, bursas o vainas tendinosas, generando cuerpos libres productores de la sintomatología. Presentamos un caso de 16 años que consulta con dolor de hombro derecho, progresivo sin antecedente de trauma previo, de 3 años de evolución. Se realizan estudios imagenológicos correspondientes llegando a la conclusión diagnostica de condromatosis sinovial de hombro. Se realiza el tratamiento quirúrgico definitivo por artroscopía, logrando remisión de los síntomas y evolución favorable sin recidiva hasta los 5 años de evolucion.

Synovial chondromatosis is a rare pathological entity where cartilaginous aspects develop from the synovial membrane of joints, bursae or tendinous sheaths, generating free bodies that produce symptoms. We present a 16-year-old male with 3 years of right shoulder pain, progressive with not previous trauma. Imaging studies are carried out, arriving at the diagnostic of synovial chondromatosis of the shoulder. The final surgical treatment is performed by arthroscopy, achieving remission of symptoms and favorable evolution without recurrence until 5 years of evolution.

Current controversies in the management of germ cell ovarian tumours.

PURPOSE OF REVIEW: Fewer than 70 new cases of malignant ovarian germ cell tumours (MOGCTs) are seen each year in the UK. Because of their rarity, no randomized trials have been reported and many of the advances in management have arisen from adopting practices developed for managing male germ cell tumours (GCTs). Not surprisingly, there have been few important publications related to ovarian germ cell tumuors over the past 2 years. We have therefore included some relevant male germ cell publications. The area in which there is greatest variability in practice globally is in the proportion of patients with stage 1a disease who go on surveillance rather than receiving adjuvant chemotherapy. Although there is increasing agreement about the best management of ovarian GCTs amongst those who treat more than five per year, many patients are still treated by doctors who usually manage epithelial ovarian cancer but rarely see these patients. RECENT FINDINGS: Novel biomarkers including microRNA profiles and DICER1 mutations, identify potential diagnostic and therapeutic targets in this group of tumours. The role of KIT mutation and amplification in the development of ovarian dysgerminoma and the use of Sunitinib, a receptor tyrosine kinase inhibitor with an effect on vascular endothelial growth factor, platelet-derived growth factor and KIT receptors in patients with platinum-resistant GCT, are novel promising approaches. SUMMARY: We will therefore highlight some key differences in management of epithelial and germ cell ovarian tumours.

Nonsurgical therapy of biliary tract cancer.

PURPOSE OF REVIEW: The management of biliary tract cancers (BTCs) has been challenging partly because of the lack of robust data to define a treatment standard. This in turn has been because of the difficulty in conducting large clinical studies in an uncommon cancer, as well as managing elderly and unwell patients. RECENT FINDINGS: Recent data and improvements in multidisciplinary patient management have established a standard of care and delivered insights into the natural history of this uncommon cancer. This is critical at a time when the incidence of this malignancy is increasing. This article describes the improving multidisciplinary management as well as seminal randomized data describing standard management. Current clinical trials that are likely to further impact on future management are described. SUMMARY: These large datasets provide insights into the natural history of BTCs hitherto not forthcoming from the many smaller studies which formed the historical evidence base. This increasing standardization of care will improve outcome for patients with BTCs and provide a platform for further research.

Pneumothorax and pneumomediastinum have only exceptionally been described in mild cases of the disease. The radiological findings, differential diagnosis and clinical course are discussed.

[Prevalence of white-coat hypertension and masked hypertension in the general population, through home blood pressure measurement]. / Prevalencia de la hipertensión de bata blanca e hipertensión enmascarada en la población general, mediante automedición domiciliaria de la presión arterial.

OBJECTIVE: To determine the prevalence of white-coat hypertension (WCH) and masked hypertension (MH) in the general population, by means of home blood pressure measurement (HBPM). DESIGN: Cross-sectional, descriptive study. SETTING: Four primary care centres. PARTICIPANTS: A sample of 1400 individuals over 18 years old, selected from the Municipal Register of Inhabitants (Huelva, Spain) and randomised and stratified by age and gender. MAIN MEASUREMENTS: Two blood pressure (BP) measurements in clinic (CBP) and 12 measurements in a week of BP by HBPM were performed (OMRON 705-CP). Pressure was seen as normal when CBP means were <140/90 mm Hg and HBPM was <135/85 mm Hg. WCH was defined as when CBP was >140/90 mm Hg and HBPM <135/85 mm Hg, and hypertension when CBP was >140 mm Hg and HBPM >135/85 mm Hg or patients were in treatment for hypertension. MH was when CBP was <140/90 mm Hg and at home was >135 mm Hg and/or 85 mm Hg. RESULTS: A total of 1153 individuals (82.35% of the sample) with mean age of 45.4 (SD, 16.1) were included: 560 men and 593 women. The prevalence of MH was 8.9% (CI+/-1.6) in the general population and 9.8% (CI+/-3.2) in individuals with hypertension. WCH prevalence was 3.6% (CI+/-1.05) overall and 12.8% (CI+/-3.6) in hypertense patients, with its prevalence increasing steadily as age groups rose (P = .001). CONCLUSIONS: The prevalence of WCH in the general population is low, whereas the prevalence of MH is high.
