Music in Medicine: Enhancing Emotion Recognition in Medical Students

Previous studies have shown that visual art courses for medical students have improved their diagnostic skills. A music course in a similar fashion may enhance their ability to recognize patient emotion in the patient’s voice. Identifying patient emotion via auditory cues allows future physicians to appropriately respond to patients’ mental states and provide empathetic care. This study proposes that medical students who complete a course in recognizing emotional cues in music will outperform a control group in correctly identifying emotion in the human voice. Participants were randomly divided into control and experimental groups, in which only the latter completed a lesson in recognizing varying emotional styles in a musical passage. After completion of the music course by the experimental group, both groups were asked to match the emotions “happy,” “sad,” “angry,” “hesitant,” and “curious” to recordings of the human voice with those emotional inflections. The latter two were considered to be the more challenging emotions to identify. Each group’s scores were compared using an independent t-test. The experimental group mean score was 0.84, which was significantly higher compared to that of the control group, 0.34 (P\u3c.05). Additionally, the control group was more likely to incorrectly identify the voice recordings with the inflections “hesitant” and “curious,” considered to be more challenging than the remaining three emotions. These results corroborated the hypothesis that students receiving a primer course in recognizing emotional cues in music would be better prepared to identify emotion in human voice. The results also imply that the music course may aid students in identifying more complex emotions that may not be explicit in a patient’s tone of voice. Medical students who are aware of their patients’ emotional state without being explicitly told may be able to foster a greater degree of doctor-patient trust via their heightened sense of empathy

Dynamic Assessment of Baroreflex Control of Heart Rate During Induction of Propofol Anesthesia Using a Point Process Method

In this article, we present a point process method to assess dynamic baroreflex sensitivity (BRS) by estimating the baroreflex gain as focal component of a simplified closed-loop model of the cardiovascular system. Specifically, an inverse Gaussian probability distribution is used to model the heartbeat interval, whereas the instantaneous mean is identified by linear and bilinear bivariate regressions on both the previous R−R intervals (RR) and blood pressure (BP) beat-to-beat measures. The instantaneous baroreflex gain is estimated as the feedback branch of the loop with a point-process filter, while the RRBP feedforward transfer function representing heart contractility and vasculature effects is simultaneously estimated by a recursive least-squares filter. These two closed-loop gains provide a direct assessment of baroreflex control of heart rate (HR). In addition, the dynamic coherence, cross bispectrum, and their power ratio can also be estimated. All statistical indices provide a valuable quantitative assessment of the interaction between heartbeat dynamics and hemodynamics. To illustrate the application, we have applied the proposed point process model to experimental recordings from 11 healthy subjects in order to monitor cardiovascular regulation under propofol anesthesia. We present quantitative results during transient periods, as well as statistical analyses on steady-state epochs before and after propofol administration. Our findings validate the ability of the algorithm to provide a reliable and fast-tracking assessment of BRS, and show a clear overall reduction in baroreflex gain from the baseline period to the start of propofol anesthesia, confirming that instantaneous evaluation of arterial baroreflex control of HR may yield important implications in clinical practice, particularly during anesthesia and in postoperative care.National Institutes of Health (U.S.) (Grant R01-HL084502)National Institutes of Health (U.S.) (Grant K25-NS05758)National Institutes of Health (U.S.) (Grant DP2- OD006454)National Institutes of Health (U.S.) (Grant T32NS048005)National Institutes of Health (U.S.) (Grant T32NS048005)National Institutes of Health (U.S.) (Grant R01-DA015644)Massachusetts General Hospital (Clinical Research Center, UL1 Grant RR025758

Antimicrobial potential of LEGUMES extracts against foodborne pathogens: A review

[EN] Background: Alternative protein sources are being investigated in response to increasing consumer demand for innovative and healthy food products of vegetable origin to replace non-sustainable animal exploitation. The Leguminosae family includes a wide variety of plants and nutritious seeds, very rich in protein with a high biological value, carbohydrates, vitamins and minerals. Not only the seeds but also the aerial parts, pods, hulls and roots have proved to be natural sources of antioxidants, and anti-inflammatory and antimicrobial compounds. Scope and approach: The present article overviews the antimicrobial potential of the most popular legumes worldwide against foodborne pathogens. Key findings and conclusions: According to the literature reviewed, soybean and chickpea are the two consumed legumes with the highest antimicrobial activity. Long-chain soy peptides (IKAFKEATKVDKVVVLWTA) have a high antimicrobial potential against both Gram-positive and Gram-negative bacteria at a concentration level of 37.2 ¿M. Also, a wide spectrum of proteins and peptides in raw chickpeas and processed extracts have exerted antimicrobial activity against foodborne pathogens when applied in the range 8¿64 ¿g/ml. These results open a new research line with good prospects regarding the development of a new generation of natural preservative ingredients and extracts to be included in novel formulated products. However, critical aspects, such as (i) the stability of antimicrobial activity during the shelf-life of newly formulated food products, and (ii) the microbial inactivation kinetics generated in novel matrices, should be covered prior to exploitation of legumes as sources of novel technological ingredients with antimicrobial potential.The present research work has been supported by funds provided by the Spanish Ministry of Economy and Competitiveness (MINECO) as the HELICOFOOD project, with reference AGL2014-53875-R.

LEARN: A multi-centre, cross-sectional evaluation of Urology teaching in UK medical schools

OBJECTIVE: To evaluate the status of UK undergraduate urology teaching against the British Association of Urological Surgeons (BAUS) Undergraduate Syllabus for Urology. Secondary objectives included evaluating the type and quantity of teaching provided, the reported performance rate of General Medical Council (GMC)-mandated urological procedures, and the proportion of undergraduates considering urology as a career. MATERIALS AND METHODS: LEARN was a national multicentre cross-sectional study. Year 2 to Year 5 medical students and FY1 doctors were invited to complete a survey between 3rd October and 20th December 2020, retrospectively assessing the urology teaching received to date. Results are reported according to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES). RESULTS: 7,063/8,346 (84.6%) responses from all 39 UK medical schools were included; 1,127/7,063 (16.0%) were from Foundation Year (FY) 1 doctors, who reported that the most frequently taught topics in undergraduate training were on urinary tract infection (96.5%), acute kidney injury (95.9%) and haematuria (94.4%). The most infrequently taught topics were male urinary incontinence (59.4%), male infertility (52.4%) and erectile dysfunction (43.8%). Male and female catheterisation on patients as undergraduates was performed by 92.1% and 73.0% of FY1 doctors respectively, and 16.9% had considered a career in urology. Theory based teaching was mainly prevalent in the early years of medical school, with clinical skills teaching, and clinical placements in the later years of medical school. 20.1% of FY1 doctors reported no undergraduate clinical attachment in urology. CONCLUSION: LEARN is the largest ever evaluation of undergraduate urology teaching. In the UK, teaching seemed satisfactory as evaluated by the BAUS undergraduate syllabus. However, many students report having no clinical attachments in Urology and some newly qualified doctors report never having inserted a catheter, which is a GMC mandated requirement. We recommend a greater emphasis on undergraduate clinical exposure to urology and stricter adherence to GMC mandated procedures

The Value of Media Studies Approaches for the Evaluation of Entertainment Education: A Case Study of East Los High.

As entertainment education (EE) becomes an increasingly popular medium for delivering health information, evaluation of EE is key to better understanding how it not only influences audiences but also how it can be better implemented. We suggest that EE evaluation has largely focused on impact while its implementation, specifically through narrative, characters, and genre, has remained unexplored. We propose drawing from theories and methods used in media studies to complement current approaches to understanding and evaluation of EE that can help improve EE for health education. East Los High serves as a case study, through which we examine the characters and the narrative demands of the telenovela genre to reveal a disproportional depiction of Latino men and women that ultimately replays familiar Latino stereotypes of criminality and exaggerated sexuality. We discuss the implications this has on the show's ability to do public health work

Efficient multiplexed genome engineering with a polycistronic tRNA and CRISPR guide-RNA reveals an important role of detonator in reproduction of Drosophila melanogaster.

Genome association studies in human and genetic studies in mouse implicated members of the transmembrane protein 132 (TMEM132) family in multiple conditions including panic disorder, hearing loss, limb and kidney malformation. However, the presence of five TMEM132 paralogs in mammalian genomes makes it extremely challenging to reveal the full requirement for these proteins in vivo. In contrast, there is only one TMEM132 homolog, detonator (dtn), in the genome of fruit fly Drosophila melanogaster, enabling straightforward research into its in vivo function. In the current study, we generate multiple loss-of-function dtn mutant fly strains through a polycistronic tRNA-gRNA approach, and show that most embryos lacking both maternal and paternal dtn fail to hatch into larvae, indicating an essential role of dtn in Drosophila reproduction

The Effectiveness of Shared Decision-making for Diabetes Prevention: 24- and 36-Month Results From the Prediabetes Informed Decision and Education (PRIDE) Trial

ObjectiveWe conducted a cluster-randomized, shared decision-making (SDM) trial offering lifestyle change, metformin, or both options, to adults at risk for diabetes in a primary care network (n = 20 practices).Research design and methodsWe used propensity score matching to identify control patients and used electronic health record data to compare weight loss at 24 and 36 months of follow-up and diabetes incidence at 36 months of follow-up.ResultsIn adjusted post hoc analyses, SDM participants (n = 489) maintained modestly greater 24-month weight loss of -3.1 lb and 36-month weight loss of -2.7 lb versus controls (n = 1,430, both comparisons P < 0.001). SDM participants who chose both lifestyle change and metformin sustained weight loss at 36 months of -4.1 lb (P < 0.001 vs. controls). We found no differences in incident diabetes (15% of SDM participants, 14% of control participants; P = 0.64).ConclusionsThis is one of the first studies to demonstrate weight loss maintenance up to 36 months after diabetes prevention SDM
