1% amputation rate in infected TKR and 0.025% amputation rate in primary TKR as a result of infection in our review. Deep infection was the main cause of amputation. Vascular complications and fractures associated with bone loss and compartment syndrome were other reasons for amputation.

Given the possible coexistence of infection by the SARS-CoV-2 with other seasonal infections, the aim is to identify differential symptoms. The role of children in intrafamily contagion and the sensitivity of reverse transcriptase polymerase chain reaction (RT-PCR) in an area with low community transmission has been studied.

Cross-sectional observational study. Patients between 0-15 years studied by RT-PCR technique due to clinical suspicion of infection by SARS-CoV-2 virus in the months of March-May 2020. Survey on symptoms and contacts. Determination of Anti-SARS-CoV-2 antibodies at least 21 days after the RT-PCR test.

126 patients were included, 33 with confirmed infection and age mean 8.4 years (95% CI 6.8-10.5) higher than not infected. Fever was the most common and with greater sensitivity. The differences found were a greater frequency of anosmia (

=.029) and headache (

=.009) among children infected with a specificity of 96.7% and 81.5% respectively. There were no differences in the duration of the symptoms. 81.8% of those infected were probably infected in the nucleus 85.2% by a parent who worked outside the home. The sensitivity of RT-PCR was 70.9% and its negative predictive value 91.1%.

The clinical picture is nonspecific and the symptoms more specific difficult to detect in younger children. Children had a reduced role in the intrafamily transmission. The sensitivity of RT-PCR could be related to a less contagiousness in children after one week of infection.

Instagram influencers have many followers and are often paid to promote products, including e-cigarettes. This experimental study assessed effects of sponsorship disclosures on perceptions of e-cigarette Instagram influencer posts.

Young adult e-cigarette users (age 18-29; N = 917) were randomly assigned to 3 experimental conditions varying the clarity of sponsorship disclosure on simulated Instagram influencer posts clear (eg, "#sponsored") ambiguous (eg, "#sp"), or no disclosure (ie, vaping-related hashtags only). After viewing each of 4 Instagram posts featuring a fictitious e-cigarette brand, participants reported hashtag recognition, ad recognition, ad trust, influencer credibility, and post engagement intentions. After viewing all posts, participants reported brand attitudes, brand use intentions, and vaping intentions.

With greater recognition of clear (but not ambiguous) disclosure hashtags, ad recognition increased (p = .001), perceptions of influencer credibility decreased (p = .022), and intentions to engage with posts decreased (p = .008). Ad trust was lower with greater hashtag recognition regardless of disclosures (p < .001). Sponsorship disclosures did not significantly affect brand attitudes, brand use intentions, or vaping intentions.

Recognizing clear sponsorship disclosures may influence young adults' perceptions of and engagement with e-cigarette Instagram posts but may not affect perceptions or use of products.

However, little is known regarding whether such measures are associated with daily experience of effort. To test this, 31 participants completed an ecological momentary assessment (EMA) protocol, answering surveys regarding the mental and physical demand of their daily activities, and also completed two effort-based decision-making tasks the Effort Expenditure for Rewards Task (EEfRT) and the Cognitive Effort Discounting (COGED) Task. Individuals who reported engaging in more mentally and physically demanding activities via EMA were also more willing to expend effort in the COGED task. However, EMA variables were not significantly associated with EEfRT decision-making. The results demonstrate the ecological, discriminant, and incremental validity of the COGED task, and provide preliminary evidence that individual differences in daily experience of effort may arise, in part, from differences in trait-level tendencies to weigh the costs versus benefits of actions.Deficits in self-regulation and motivation are central to depression. Using motivational intensity theory (Brehm & Self, 1989), the present research examined how depressive anhedonia influences effort during a piece-rate appetitive task. In piece-rate tasks, people can work at their own pace and are rewarded for each correct response, so they can gain rewards more quickly by expending more effort. A sample of community adults (n = 78) was evaluated for depressive anhedonia using a structured clinical interview, yielding depressive anhedonia and control groups. Participants completed a self-paced cognitive task, and each correct response yielded a cash reward (3 cents or 15 cents, manipulated within-person). Using impedance cardiography, effort-related physiological activity was assessed via the cardiac pre-ejection period (PEP).

Compared to the control group, the depressive anhedonia group showed significantly less baseline-to-task change in PEP, and they performed marginally worse on the task. The experiment supports the predictions made by applying motivational intensity theory to depression and offers a useful paradigm for evaluating anhedonic effects on effort while people are striving for appealing rewards.From March to June of 2020, Montefiore Medical Center faced one of the most acute surges in hospital admissions and critical illness ever experienced in the United States due to the severe acute respiratory syndrome coronavirus 2 pandemic. The pandemic had not yet spread to most of the country, and there was a relative deficit of knowledge regarding treatments, prognosis, and prevention of the virus, making this experience relatively unique and challenging. As part of a surge plan, our institution converted nonclinical spaces, such as conference rooms, to inpatient care settings and placed elective surgeries on hold to free up resources. A central deployment office suspended anesthesiology resident rotations and instead assigned them to intensive care settings based on need. For the Montefiore Medical Center Department of Anesthesiology, preserving its academic mission and commitment to Graduate Medical Education was essential. Adaptations included changing the residency rotation structure to biweekly, converting didactics online, ensuring adequate case numbers for graduating residents, actively pursuing wellness interventions, and prioritizing the safety of the residents caring for patients with coronavirus disease 2019 (COVID-19). In this brief report, the authors discuss solutions devised to maintain the quality of anesthesiology resident education and training as much as possible during the COVID-19 surge.

Underserved sub-Saharan countries have 0.1 to 1.4 anesthesia providers per 100 000 citizens, below the Lancet Commission's target of 20 per 100 000 needed for safe surgery. Most of these anesthesia providers are nurse anesthetists, with anesthesiologists numbering as few as zero in some nations and 2 per 7 million in others, such as Sierra Leone. In this study, we compared 2 simulation-based techniques for training nurse anesthetists on the Universal Anaesthesia Machine Ventilator-rapid-cycle deliberate practice and mastery learning.

A 2-week Universal Anaesthesia Machine Ventilator course was administered to 17 participants in Sierra Leone. Seven were randomized to the rapid-cycle deliberate practice group and 10 to the mastery learning group. Participants underwent baseline and posttraining evaluations in 3 scenarios general anesthesia, intraoperative power failure, and postoperative pulmonary edema. Performance was analyzed based on checklist performance scores and the number of times participants wereersal Anaesthesia Machine Ventilator in 3 separate scenarios. The data did not indicate any difference between these methods; however, a larger sample size may support or refute our findings.

Although approximately half of US medical students are now women, anesthesiology training programs have yet to achieve gender parity. Women trainees' experiences and needs, including those related to motherhood, are increasingly timely concerns for the field of anesthesiology. At present, limited data exists on the childbearing experiences of women physicians in anesthesiology training.

In March of 2018, we surveyed women members of the American Society of Anesthesiologists via email. Questions addressed pregnancy, maternity leave, lactation, and motherhood. We analyzed data from a subset of respondents who were pregnant or had children during training and graduated in the year 2000 or later.

A total of 542 respondents who completed training in the year 2000 or after reported 752 pregnancies during anesthesia training. A maternity leave had a median length of 7 weeks and did not change significantly over time. During many pregnancies, women felt their leave was inadequate (59.6%) or felt discouraged froevaluate how these changes have impacted anesthesiology trainees.

Fiberoptic intubation (FOI) is key in managing difficult airways. Good scope control increases efficiency and patient safety. Understanding the gap between novices and experts in scope control would help medical educators develop a feedback-based teaching approach for novices. We designed and used a checklist for evaluating the gap in fiberoptic scope control between novices and experts.

Twelve first-year anesthesiology residents (novice group) attended a lecture, followed by hands-on practice with a fiberoptic scope on a manikin. Five staff anesthesiologists (expert group) only did the hands-on practice. After practice, each participant was video-recorded while conducting an FOI on the manikin. Two senior anesthesiologists developed and used a 7-item checklist to assess the FOIs. Checklist scores and total times for FOIs were compared between groups using the Mann-Whitney

test. Internal consistency of the checklist items, interrater reliability, and the relationship between checklist score and total time for FOI were assessed with Cronbach alpha, Cohen kappa, and the Pearson correlation coefficient, respectively.

Experts had higher checklist scores than novices (

= .0016). The item with the lowest success rate for novices (50%) was keeping the scope straight. Novices spent more time on the FOI than experts (

= .0005). Cronbach alpha, Cohen kappa, and the Pearson correlation coefficient were 0.8699, 0.75, and -0.9454, respectively.

Our checklist was used to detect differences in fiberoptic scope control skills between novices and experts. With a video-based assessment method, it can be used to develop a feedback-based teaching method for fiberoptic scope control.
