RESUMEN

Simulated (sim) racing is an emerging esport that has garnered much interest in recent years and has been a relatively under-researched field in terms of expertise and performance. When examining expertise, visual attention has been of particular interest to researchers, with eye tracking technology commonly used to assess visual attention. In this study, we examined the overt visual attention allocation of high- and low-skilled sim racers during a time trial task using Tobii 3 glasses. In the study, 104 participants were tested on one occasion, with 88 included in the analysis after exclusions. Participants were allocated to either group according to their fastest lap times. Independent t-tests were carried out with sidak corrections to test our hypotheses. Our results indicate that when eye tracking metrics were normalised to the lap time and corner sector time, there was a difference in the relative length of overt attention allocation (fixation behaviour) as lower-skilled racers had significantly greater total fixation durations in laps overall and across corner sectors when normalised (p = 0.013; p = 0.018). Interestingly, high- and low-skilled sim racers differed in where they allocated their attention during the task, with high-skilled sim racers allocating significantly less overt attention to the track relative to other areas of the display (p = 0.003). This would allow for higher-skilled racers to obtain relatively more information from heads-up display elements in-game, all whilst driving at faster speeds. This study provides evidence that high-skilled sim racers appear to need significantly less overt attention throughout a fast lap, and that high- and low-skilled sim racers differ in where they allocate their attention while racing.

RESUMEN

Evaluating salmon hatchery supplementation programs requires assessing not only program objectives but identifying potential risks to wild populations as well. Such evaluations can be hampered by difficulty in distinguishing between hatchery- and wild-born returning adults. Here, we conducted 3 years (2011-2013) of experimental hatchery supplementation of sockeye salmon in Auke Lake, Juneau, Alaska where a permanent weir allows sampling and genotyping of every returning adult (2008-2019). We identified both hatchery- and wild-born returning adults with parentage assignment, quantified the productivity (adult offspring/spawner) of hatchery spawners relative to that of wild spawners, and compared run timing, age, and size at age between hatchery- and wild-born adults. Hatchery-spawning females produced from approximately six to 50 times more returning adults than did naturally spawning females. Supplementation had no discernable effect on run timing and limited consequences for size at age, but we observed a distinct shift to younger age at maturity in the hatchery-born individuals in all three brood years. The shift appeared to be driven by hatchery-born fish being more likely to emigrate after one, rather than two, years in the lake but the cause is unknown. In cases when spawning or incubation habitat is limiting sockeye salmon production, hatchery supplementation can be effective for enhancing the number of returning adult fish but not without the risk of phenotypic change in the recipient population, which can be an undesired outcome of hatchery supplementation. This study adds to a growing body of evidence suggesting that phenotypic change within a single generation of captive spawning might be widespread in salmon hatchery programs.

RESUMEN

Recent work demonstrates that those who regularly play action video games (AVGs) consistently outperform non-gamer (NG) controls on tests of various cognitive abilities. AVGs place high demands on several cognitive functions and are often engaged with for long periods of time (e.g., over 2 h), predisposing players to experiencing cognitive fatigue. The detrimental effects of cognitive fatigue have been widely studied in various contexts where accurate performance is crucial, including aviation, military, and sport. Even though AVG players may be prone to experiencing cognitive fatigue, this topic has received little research attention to date. In this study, we compared the effect of a cognitively fatiguing task on the subsequent cognitive performance of action video game players and NG control participants. Our results indicated AVGs showed superior spatial working memory and complex attention abilities while showing no difference from NGs on simple attention performance. Additionally, we found that our cognitive fatigue and control interventions did not differentially affect the cognitive performance of AVGs and NGs in this study. This pre-registered study provides evidence that AVGs show superior cognitive abilities in comparison to a non-gaming population, but do not appear more resilient to cognitive fatigue.

RESUMEN

BACKGROUND: Whilst feedback is an essential component of clinical education, it is often lacking in clinical workplaces due to competing priorities. Peer feedback has been proposed as a potential solution but remains underexplored in terms of practicality and effects. We aimed to examine the experiences of peer feedback among paediatric trainees, and the associated feedback culture. METHODS: Following an Interpretative Phenomenological Analysis approach, the personal experiences of 12 paediatric trainees were explored using semi-structured interviews. Interpretive themes were developed between the transcripts using processes of abstraction, subsumption, contextualisation, and cross-case analysis. Themes were subsequently subjected to member checking and peer debriefing processes. RESULTS: We found that peer feedback was influenced by three contextual factors, namely, prevalent feedback culture, interpersonal consent, and the quality of relationships. Peer feedback culture was lacking in clinical workplaces. Feedback between peers was constrained by avoiding criticism and maintaining work relationships. Social and cultural norms inhibited constructive peer feedback without explicit consent. CONCLUSIONS: Enabling peer feedback in clinical settings requires attention to cultural, relational, and consent barriers. Potential approaches should include helping clinicians to develop greater cultural reflexivity, resident training in how to be peer educators, and enhancing institutional supports for peer feedback.

RESUMEN

The trisomy of chromosome 21, the smallest autosome, is associated with significant systemic manifestations in addition to intellectual disability. The triplication of this chromosome, known as Down syndrome (DS) is also associated with several manifestations in the eye, and ocular adnexae. People with DS have a variety of ophthalmic conditions, some of which require intervention. The variable systemic and ophthalmic presentations in DS can make the delivery of eye care challenging. We highlight common ophthalmic presentations in people with DS, as well as the practical implications of delivering eye examinations for this complex needs population. We aim to aid clinicians involved in the ophthalmic care of people with DS in both clinical and research settings.

RESUMEN

Objective To determine the pattern of microbes responsible for urinary tract infections and their susceptibility to different antibiotics. Method This is a cross-sectional study conducted at Quetta, Pakistan. The urine samples of 400 patients were collected and sent for culture and sensitivity analysis. The results were recorded on an excel datasheet. Descriptive statistics were used to describe the data. Results Out of 400 urine samples, 266 samples were culture positive for microorganisms. The most common organism on analysis was Escherichia coli 123/266 (46.24%) followed by Staphylococcus saprophyticus 59/266 (22.18%) and Klebsiella pneumonia 49/266 (18.42%). Gram-negative microorganisms were most susceptible to fosfomycin, cefoperazone/sulbactam, and meropenem. Gram-positive microorganisms were most susceptible to fosfomycin, cefoperazone/sulbactam, meropenem, and amoxicillin/clavulanate. High rates of resistance in E. coli were observed to most commonly prescribed broad-spectrum antibiotics; ceftriaxone (64.35%), cefotaxime (76.54%), ceftazidime (49.43%), cefepime (53.44%), levofloxacin (71.26%), and amoxicillin/clavulanate (70.31%). E. coli was the major multidrug-resistant organism. Conclusion High rates of antibiotic resistance and multi-drug resistance were revealed in this study due to the widespread and injudicious use of broad-spectrum antibiotics. Thus, it is highly recommended to regulate the pharmacies. Physicians should judiciously prescribe antibiotics and practice the culture and sensitivity of urine samples rather than blind prescription. Continued surveillance on uropathogens prevalence and resistance, new and next-generation antibiotics, and rapid diagnostic tests to differentiate viral from bacterial infections is the need of time.

RESUMEN

AIM: The neonatal intensive care unit can be a stressful environment for parents. The Beads of Courage program is an arts-in-medicine, psychosocial intervention, designed to strengthen and support children and families who are coping with serious or life-threatening illness. We hypothesised that the program would improve the parent experience in the neonatal unit. METHODS: Infants less than 32 weeks' gestation were eligible for enrolment on the program. The study was conducted from 2016 to 2018. A 13 point questionnaire was sent to participating parents post discharge from the unit including a combination of Likert scale and open-ended questions. RESULTS: During the study period 123 infants were enrolled. Mean gestational age was 27.7(±2.2) weeks and median length of stay was 49 days (lower quartile 34; upper quartile 76). All respondents rated the program as "helpful and enjoyable" with 72.5% rating it "extremely helpful and enjoyable", 85% felt the program made their stay in the neonatal unit easier. CONCLUSION: The Beads of Courage program was found to be an extremely popular initiative for parents in a neonatal unit setting and was found to be a useful adjunct to communication and inclusion of parents in the care of their infants. SUMMARY: The Beads of Courage program in a NICU setting was found to be very helpful for parents in improving awareness of procedures and understanding overall care of their infants. Parents felt their journey was made easier with the additional engagement and communication with being in the program.

RESUMEN

Chorea is caused by a number of conditions, including genetic, metabolic derangements, infections, drugs, toxins, tumors, and disorders of the immune and inflammatory system of the body. Huntington's disease (HD) is the most common genetic cause of chorea. Systemic lupus erythematosus (SLE) is an autoimmune condition. Common symptoms include oral ulcers, joint pain, malar or discoid rashes, photosensitivity, and blood dyscrasias. It can involve the heart, lungs, kidneys, and brain. SLE can cause neuropsychiatric manifestations like psychosis, seizures, headache, confusion, and stroke. Chorea is a known symptom of SLE. HD is now recognized to involve more than one system and is associated with a number of comorbid conditions. We report the first case of hereditary choreiform disorder associated with and aggravated by SLE. This is also the first case report of probable Huntington disease from Balochistan, Pakistan. We report a 19-year-old girl with choreiform disorder and a family history of chorea. Choreiform disorder was present in her paternal grandmother and uncles. She presented with fever, cough, and aggravation of choreiform movements of upper and lower limbs for 10 days. She also complained of pain in the small joints of her hands and feet, oral ulcers, hair loss, and aggravation of choreiform movements for two and half months. Probable differential diagnoses of HD, Wilson's disease, and other types of hereditary chorea, aggravated by infections, SLE, or Covid-19, were made. Her initial lab results revealed pancytopenia, increased D-dimers and serum ferritin, positive antinuclear antibodies (ANA), and anti-double-stranded DNA (anti-dsDNA). Her C3 and C4 complement factors were low. The rest of the lab test results, including polymerase chain reaction (PCR) coronavirus disease (COVID-19), blood culture, and malaria, were negative. Thus, a diagnosis of hereditary chorea associated with and aggravated by SLE was made. Hereditary choreiform disorders can be associated with and aggravated by autoimmune conditions like SLE. Thus, it is recommended to be vigilant and have a low threshold for diagnosing co-existing autoimmune conditions like SLE in patients with hereditary choreiform disorder.

RESUMEN

BACKGROUND: The COVID-19 pandemic has drastically affected everyone in a hit or miss manner. Since it began, evidence of the neuro-invasive potential of the virus has been intensifying significantly. Several pathways have been hypothesized to elucidate the neurotropic nature of SARS-CoV2. It is the need of the hour to collect vital information. OBJECTIVE: To evaluate and correlate the neuro-radiological and neurological manifestations in patients diagnosed with SARS-CoV2.To identify neuro-invasive pathways of COVID infection. METHODS: Relevant studies were identified through four databases-the Cochrane Library, PubMed, Science Direct, and Web of Science. These were searched using relevant keywords-"COVID-19," "SARS-CoV2," "neurological manifestations," "neuroimaging," "CT," and "MRI." Relevant articles were screened according to a pre-defined inclusion and exclusion criteria from December 2019 to August 2020. RESULTS: Our review included a total of 63 full text publications with 584 patients, composed mainly of observational studies, case reports, and case series. The most common neurological manifestations associated with COVID-19 were altered mental status, stroke, and paralysis. About 17.85% patients who underwent neuroimaging were found to be having ischemic changes suggestive of a stroke. This was followed by hemorrhagic changes as the second most common finding. The most commonly involved vessel was the Middle Cerebral Artery. Besides stroke, we found that SARS-CoV2 could be the cause for new-onset seizures, Guillain-Barre Syndrome, encephalitis, and many other severe neurological diseases. CONCLUSION: The information that we have obtained so far will prove dynamic to healthcare providers working against the COVID-19 pandemic. It is necessary to be aware of these atypical neurological findings for the early diagnosis and treatment of COVID-19 infected patients. However, to completely understand the connection between SARS-CoV2 and the nervous system, further research is necessary.

RESUMEN

The treatment of myocardial infarction (MI) in coronavirus disease 2019 (COVID-19)-positive patients is both controversial and challenging, particularly in a healthcare setup unable to fulfill COVID-19 protocols. In this report, we describe a case of a COVID-19-positive patient admitted with COVID-19 pneumonia treated symptomatically with a non-rebreathing mask, dexamethasone, remdesivir, and low-molecular-weight heparin (LMWH). On day two of the hospital stay, the patient developed inferolateral wall myocardial infarction (MI) without hemodynamic instability. He was treated successfully with thrombolytic (streptokinase) with no severe complications. However, his hospital stay was further complicated by decreasing oxygen saturation and rising inflammatory markers including procalcitonin and IL-6, suggesting superimposed bacterial infection. Thereafter, he was placed on BiPAP oxygen, and aggressive antibiotic therapy including tigecycline along with clindamycin and moxifloxacin was initiated. He showed gradual daily improvements and was discharged after a prolonged hospital stay. To decrease the exposure and spread of COVID-19 infection among the healthcare workers, when there is a deficiency in medical staff, and no negative-pressure catheterization laboratory, thrombolytic can be used for treatment in low-risk, hemodynamically stable MI during this pandemic. However, this needs further research.

RESUMEN

Hyperphosphorylated tau protein is a pathological hallmark of numerous neurodegenerative diseases and the level of tau pathology is correlated with the degree of cognitive impairment. Tau hyper-phosphorylation is thought to be an early initiating event in the cascade leading to tau toxicity and neuronal death. Inhibition of tau phosphorylation therefore represents an attractive therapeutic strategy. However, the widespread expression of most kinases and promiscuity of their substrates, along with poor selectivity of most kinase inhibitors, have resulted in systemic toxicities that have limited the advancement of tau kinase inhibitors into the clinic. We therefore focused on the CNS-specific tau kinase, TTBK1, and investigated whether selective inhibition of this kinase could represent a viable approach to targeting tau phosphorylation in disease. In the current study, we demonstrate that TTBK1 regulates tau phosphorylation using overexpression or knockdown of this kinase in heterologous cells and primary neurons. Importantly, we find that TTBK1-specific phosphorylation of tau leads to a loss of normal protein function including a decrease in tau-tubulin binding and deficits in tubulin polymerization. We then describe the use of a novel, selective small molecule antagonist, BIIB-TTBK1i, to study the acute effects of TTBK1 inhibition on tau phosphorylation in vivo. We demonstrate substantial lowering of tau phosphorylation at multiple sites implicated in disease, suggesting that TTBK1 inhibitors may represent an exciting new approach in the search for neurodegenerative disease therapies.

RESUMEN

AIM: To investigate the relationship between the presenting clinical and demographic characteristics in first-episode psychosis (FEP) patients with their clinical diagnostic grouping 1 year later. METHODS: Data from 1014 first-presentation psychosis patients from seven London-based Early Intervention Services were extracted from the MiData audit database. Associations between clinical and demographic measures at presentation and clinical diagnosis made at 1 year were assessed with analysis of variance (ANOVA) and Chi-square tests. RESULTS: The sample comprised 76% of patients with schizophrenia-spectrum diagnoses, 9% with manic psychoses (MP) and 6% with depressive psychoses. Compared to the other 2 groups, patients who were diagnosed as having MP were younger, with higher education and shorter duration of untreated psychosis, and had higher Young Mania Rating Scale scores at presentation and lower Positive and Negative Syndrome Scale (PANSS) negative scores. Patients diagnosed at 1 year as having depressive psychosis were older and more likely to be white, with the lowest PANSS positive scores at baseline. Patients diagnosed at 1 year as having schizophrenia spectrum diagnoses were more likely to be males. Patients in the 3 diagnostic subgroups of psychosis differed on both clinical and demographic characteristics at presentation. CONCLUSIONS: There were significant clinical and demographic differences at presentation between FEP patients who received different clinical diagnoses at 1 year. Future work should determine the extent to which these differences can be used to guide clinical care.

RESUMEN

AIM: Duration of untreated psychosis (DUP) is considered as a key prognostic variable in psychosis. Yet, it is unclear whether a longer DUP causes worse outcomes or whether reported associations have alternative explanations. METHODS: Data from 2 cohorts of patients with first episode psychosis were used (n = 2134). Measures of DUP were assessed at baseline and outcomes at 12 months. Regression models were used to investigate the associations between DUP and outcomes. We also investigated whether any associations were replicated using instrumental variables (IV) analysis to reduce the effect of residual confounding and measurement bias. RESULTS: There were associations between DUP per 1-year increase and positive psychotic symptoms (7.0% in symptom score increase 95% confidence interval (CI) 4.0%, 10.0%, P < .001), worse recovery (risk difference [RD] 0.78, 95%, CI 0.68, 0.83, P < .001) and worse global functioning (0.62 decrease in functioning score 95% CI -1.19, -0.04, P = .035). There was no evidence of an association with negative psychotic symptoms (1.0%, 95%, CI -2.0%, 5.0%, P = .455). The IV analysis showed weaker evidence of associations in the same direction between DUP per 1-year increase and positive psychotic symptoms, recovery and global functioning. However, there was evidence of an inverse association with negative psychotic symptoms (decrease of 15.0% in symptom score 95% CI -26.0%, -3.0%, P = .016). CONCLUSIONS: We have confirmed previous findings of a positive association between positive psychotic symptoms, global functioning and recovery and DUP using regression analysis. IV analysis shows some support for these findings. Future investigation using IV analysis should be repeated in large data sets.

RESUMEN

OBJECTIVES: Pelvic floor hypertonic disorder is characterized by an involuntary spasm of the levator ani muscles and is associated with several clinical syndromes. Several treatment options have been described; however, treatment efficacy data are limited. The objective of this study was to determine the efficacy of intravaginal diazepam for the treatment of pelvic pain secondary to levator ani muscle spasm in comparison to placebo. METHODS: Adult women with complaints of pelvic pain, who were noted to have levator ani muscle spasm on physical examination, were approached for enrollment in a double-blind, placebo-controlled, randomized clinical trial. Eligible participants were randomized to receive 10-mg diazepam capsules or identical-appearing placebo capsules. The primary outcome was the change in pain scores measured by a 100-mm visual analog scale at 4 weeks. Several validated questionnaires were similarly assessed as secondary outcomes. RESULTS: In total, 49 women were randomized (25 in the diazepam arm and 24 in the placebo arm). At 4 weeks, 35 women returned for follow-up and had complete data available analysis. There was no difference in visual analog scale scores between the treatment groups after 4 weeks (50 vs 39 mm, for diazepam and placebo, respectively; P = 0.36). There were also no differences noted in the questionnaire scores. CONCLUSIONS: It is unlikely that self-administered intravaginal diazepam suppositories promote an improvement in the 100-mm visual analog scale of 20 mm or more or other substantial symptom improvement in women with pelvic floor hypertonic disorder.

RESUMEN

Pacific salmon are a keystone resource in Alaska, generating annual revenues of well over ~US$500 million/year. Due to their anadromous life history, adult spawners distribute amongst thousands of streams, posing a huge management challenge. Currently, spawners are enumerated at just a few streams because of reliance on human counters and, rarely, sonar. The ability to detect organisms by shed tissue (environmental DNA, eDNA) promises a more efficient counting method. However, although eDNA correlates generally with local fish abundances, we do not know if eDNA can accurately enumerate salmon. Here we show that daily, and near-daily, flow-corrected eDNA rate closely tracks daily numbers of returning sockeye and coho spawners and outmigrating sockeye smolts. eDNA thus promises accurate and efficient enumeration, but to deliver the most robust numbers will need higher-resolution stream-flow data, at-least-daily sampling, and a focus on species with simple life histories, since shedding rate varies amongst jacks, juveniles, and adults.

RESUMEN

INTRODUCTION: Transesophageal echocardiography (TEE) is a well-established method of evaluating cardiac pathology. It has many advantages over transthoracic echocardiography (TTE), including the ability to image the heart during active cardiopulmonary resuscitation. This prospective simulation study aims to evaluate the ability of emergency medicine (EM) residents to learn TEE image acquisition techniques and demonstrate those techniques to identify common pathologic causes of cardiac arrest. METHODS: This was a prospective educational cohort study with 40 EM residents from two participating academic medical centers who underwent an educational model and testing protocol. All participants were tested across six cases, including two normals, pericardial tamponade, acute myocardial infarction (MI), ventricular fibrillation (VF), and asystole presented in random order. Primary endpoints were correct identification of the cardiac pathology, if any, and time to sonographic diagnosis. Calculated endpoints included sensitivity, specificity, and positive and negative predictive values for emergency physician (EP)-performed TEE. We calculated a kappa statistic to determine the degree of inter-rater reliability. RESULTS: Forty EM residents completed both the educational module and testing protocol. This resulted in a total of 80 normal TEE studies and 160 pathologic TEE studies. Our calculations for the ability to diagnose life-threatening cardiac pathology by EPs in a high-fidelity TEE simulation resulted in a sensitivity of 98%, specificity of 99%, positive likelihood ratio of 78.0, and negative likelihood ratio of 0.025. The average time to diagnose each objective structured clinical examination case was as follows: normal A in 35 seconds, normal B in 31 seconds, asystole in 13 seconds, tamponade in 14 seconds, acute MI in 22 seconds, and VF in 12 seconds. Inter-rater reliability between participants was extremely high, resulting in a kappa coefficient across all cases of 0.95. CONCLUSION: EM residents can rapidly perform TEE studies in a simulated cardiac arrest environment with a high degree of precision and accuracy. Performance of TEE studies on human patients in cardiac arrest is the next logical step to determine if our simulation data hold true in clinical practice.

RESUMEN

INTRODUCTION: Although infrequent, when encountered vesicovaginal fistulas (VVF) are a difficult condition for both patients and physicians alike. After the first robotic repair was described in 2005, this has been an increasingly common treatment modality. At our institution between 2009 and 2014, eleven of these patients were evaluated and treated with robotic repair. However, fibrin sealant was used in place of the traditional tissue flap. Included are six patients who had previously undergone operative repair. MATERIALS AND METHODS: After IRB approval was obtained, a retrospective study was undertaken to identify patients with VVF. Inclusion criteria were operative repair utilizing a da Vinci robotic system; there were no exclusion criteria. A total of eleven patients were identified, and in each case, a robot assisted laparoscopic approach was utilized and Tisseel fibrin sealant was used in lieu of tissue interposition. RESULTS: All patients underwent successful repair of their VVF without evidence of recurrence at a mean follow up of 15.6 months. CONCLUSIONS: Robotic vesicovaginal fistula repair with fibrin sealant seems to be a safe and viable alternative to the traditional repair utilizing a tissue flap.

RESUMEN

We retrospectively examined prophylactic antibiotic use and documentation of wound classification in patients having gynecologic surgery at a tertiary hospital. Of the 326 cases reviewed, 175 (54%) received prophylactic antibiotics when not indicated according to guidelines of the American College of Obstetricians and Gynecologists. Antibiotic administration varied significantly (P < 0.02) among the different types of surgery, being given in 82% of laparoscopic cases, 35% of nonobstetrical dilation and curettage and operative hysteroscopy procedures, and 51% of open abdominal procedures. There were no recorded episodes of anaphylaxis or pseudomembranous colitis. In conclusion, antibiotic use is high among gynecologic surgeons at a tertiary hospital, but this use was unnecessary.

RESUMEN

AIM: Men and women have historically been shown to differ in their presentation and outcome of psychotic disorders and thus are likely to have different treatment needs. It is unclear whether Early Intervention Services (EIS) are able to provide equitable care for both men and women presenting for the first time with psychosis. The main aim of this study was to explore gender differences for first-presentation psychosis patients at the time of their referral to inner-city EIS and their outcomes 1 year later. METHODS: Audit data were utilized from 1098 first-presentation psychosis patients from seven EIS across London, UK, collected via the computerized MiData package. Binary logistic regression was employed to detect potential associations between gender and (i) initial clinical presentation (including duration of untreated psychosis, pathways to care, risk behaviours); and (ii) 1-year clinical and functional outcomes. RESULTS: At entry to EIS, male patients presented with more violent behaviour whereas female patients had more suicide attempts. Following 1 year of EIS care, men still presented as more violent towards others whereas women were more likely to have been admitted to a psychiatric ward. CONCLUSION: Gender differences in clinical outcome, service use and risk behaviours were apparent within the first year of specialist psychosis care. This may be partly due to the different pathways to care taken by men and women and differences in clinical presentation. Greater focus on the specific needs of each gender by EIS in detection and intervention is required to improve equality of outcome.
