Mirror image: Recurrent Takotsubo cardiomyopathy with variable regional involvement

Takotsubo cardiomyopathy (TCM), a stress-induced cardiomyopathy, is a well-recognised cause of left ventricular dysfunction. It commonly presents similar to acute coronary syndrome with chest, dyspnoea, and electrocardiographic changes consistent with ischaemia and elevations of cardiac markers. Takotsubo cardiomyopathy often presents with acute myocardial stunning without evidence of coronary artery disease or atherosclerotic disease that is out of proportion to the demonstrated disease. Takotsubo cardiomyopathy has characteristic left ventriculography and radiographic findings – including left ventricular hypokinesis, adjacent areas of hyperkinesis, and variable regional involvement (i.e. apical, mid-ventricular, or basal ballooning patterns). Recurrent disease can occur and is often found to have similar ventricular wall dysfunction patterns. However, we present an uncommon case of possible recurrent Takotsubo cardiomyopathy that was found to have variable regional involvement

The Use of Weekly Podcasts as a Medium to Supplement Academic Internal Medicine Residency Didactics

INTRODUCTION: The majority of resident physicians in the United States are from the Millennial Generation (born 1981 to 1996), currently aged 23 to 38 (1). It is estimated that 93% of Millennials have a smart phone (2). Podcasts represent almost 10% of audio listening among millennials (3), with the second-most preferred type of podcast among millennials being educational (28%) (4). With this in mind, and in recognition of the demanding schedule of residents and interns on inpatient wards, the UNM Internal Medicine chief residents developed a podcast to supplement and reinforce the concepts taught in afternoon rounds on the inpatient wards service at UNM Hospital. MATERIALS AND METHODS: The podcast is available for free on Apple Podcasts as well as the UNM IM Chiefs website (imchiefs.unm.edu) Typical duration is approximately 15 minutes, allowing for completion of an entire episode within a typical car commute. Clinical pearls are presented based on a case seen at UNM Hospital through a conversational method amongst the chief residents. We surveyed interns and residents on their opinion and understanding of afternoon report didactics before and after the implementation of the podcast using a 0 to 10 scale. RESULTS: With respect to the survey responses collected, data thus far gathered does not show a positive/well-received response to the implementation of the podcasts. The only statistically significant before/after change was a decrease in overall AR satisfaction (p\u3c0.05) Comments in general reflected the negative perception residents have with having to attend didactics as an ACGME requirement while they are on a busy inpatient wards service. CONCLUSIONS: The addition of a supplemental podcast on topics taught at afternoon report did not improve resident satisfaction with required didactics. The increased negativity reflecting afternoon report on the post-intervention survey may be confounded due to a busier inpatient load at the time of the second survey, or from resident burnout as the year progressed.

A New Framework for Network Disruption

Traditional network disruption approaches focus on disconnecting or lengthening paths in the network. We present a new framework for network disruption that attempts to reroute flow through critical vertices via vertex deletion, under the assumption that this will render those vertices vulnerable to future attacks. We define the load on a critical vertex to be the number of paths in the network that must flow through the vertex. We present graph-theoretic and computational techniques to maximize this load, firstly by removing either a single vertex from the network, secondly by removing a subset of vertices.Comment: Submitted for peer review on September 13, 201

The Addition of Bromine to Crotonic Acid and to Ethyl Crotonate under Various Conditions

Many chemical and physical reactions are accompanied by changes in weight of the reactants due to evaporation of liquids, evolution of gases, or adsorption of gases. Studies are made using data which show the manner in which the weight changes with time. Kinetic studies are made from a knowledge of the rate of loss or gain of a component. The drying of a precipitate to constant weight involves a loss in weight. Rates of evaporation of liquids from different types of surfaces involve changes of weight as a function of time. Several instruments and methods are used to follow weight changes. Gas buret systems are used to measure the volume of a gaseous component which is adding to or subtracting from the weight of a reactant. The ordinary analytical balance is used to follow weight changes by making intermittent weighings. This latter method involves tedious operations and interruptions of the treatment of the reactants. Effort has been put forth to devise instruments which will automatically weigh substances and record these weighings on some type of graph. Gregg and Wintle (1) devised a glass automatic electrical sorption balance. Gregg (2) later described a recording system for this type balance. Eyrand (3) reported a glass sorption balance of a somewhat different type. Duval (4) described a thermal balance that automatically records changes in weight on film. Described in this paper is an instrument attached to a modified ordinary analytical balance which automatically records on graph paper changes in weight as a function of time
