An Unusual Case of Haemophilus parainfluenzae Endocarditis in a Young Patient With Crohn's Disease.

We present a rare case of infective endocarditis (IE) associated with Haemophilus parainfluenzae in a 40-year-old male patient with a history of Crohn's Disease (CD). A complete workup, including an echocardiogram and blood cultures, revealed mitral valve vegetation colonized by H. parainfluenzae. The patient was started on appropriate antibiotics with follow-up for outpatient surgery. This case discusses the potential for ectopic colonization of heart valves by H. parainfluenzae in patients with CD. The presence of this organism as the offending agent in this patient's case of IE shines a light on the pathogenesis of CD. Although uncommon, CD-associated bacterial seeding should be a differential when assessing young patients with IE.

The Effects of COVID-19 on Physicians' Perceived Ability to Provide Care for Patients With Type II Diabetes Mellitus.

Background and objective The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), presents multiple, diverse challenges to providing appropriate medical care, especially in terms of medication and treatment adherence for chronic diseases such as type 2 diabetes mellitus (T2DM). The COVID-19 pandemic has exacerbated these barriers by potentially forcing physicians to modify their treatment plans due to limitations on in-person visits and changes to patients' financial and social support systems. It remains uncertain whether physicians believe they can provide the same standard of care using telehealth technology or other means to their patients during the pandemic. The goal of this study was to explore physician perceptions about their ability to provide care to patients with T2DM during the COVID-19 pandemic. Methodology This cross-sectional study collected data between January 25, 2021, and February 2, 2021, using an anonymous, self-administered online survey involving DO and MD physicians including residents treating patients with T2DM. The survey was administered via REDCap and collected data on participant demographics, attitudes, perceptions, knowledge, and prior and current (COVID-19-era) experience with care for T2DM patients. Physicians registered with the Florida Department of Health with publicly available emails were invited to participate. Results The survey showed that during the COVID-19 pandemic, 57.9% of physicians (n=48) believed that their patients have a weaker social support system; 68.7% (n=57) modified their patient care plans due to patients' financial difficulties; 78.4% (n=65) believed a regular physical exam is necessary to properly treat patients; 48.2% (n=40) did not believe they had a more complete picture of the case with remote consultations; 47.0% (n=39) were not as satisfied with remote consultations as with face-to-face patient visits; 68.7% (n=57) believed telehealth is necessary to adequately treat patients; 38.5% (n=32) have been less likely to refer their patients to other providers or specialists; 45.8% (n=38) reported concerns over admitting their patients to the hospital for acute medical care; 61.5% (n=51) reported having more patients delay scheduling their routine follow-up care; 61.5% (n=51) believed their patients have been less compliant with the healthcare plans recommended to them. Conclusions The study showed that COVID-19 has significantly impacted physicians' perceptions and abilities to provide care for patients with T2DM. COVID-19 has negatively impacted several crucial aspects of diabetes management, including consistent in-person examinations, social support, and referral to other required services, which could result in long-term consequences for these patients. Furthermore, our study suggests that physicians may not be as satisfied with the care they are able to provide via remote consultations as they are with in-person visits, which has significant implications as we move toward a more telehealth-driven healthcare delivery system.

Heat-related changes in skin tissue dielectric constant (TDC).

The impact of 20 min of whole-body heating (WBH) on the tissue dielectric constant (TDC) of forearm and hand skin was evaluated in 24 young adults. TDC was measured in triplicate at 300 MHz using an open-ended transmission line method in which the effective measurement depth was about 2 mm. TDC measurements are an effective way to assess and track localized oedema and lymphoedema. The underlying hypothesis was that heat-induced eccrine gland activation would increase TDC values via an increase in fluid within the TDC measurement volume. The goal was to test this concept and to determine the magnitude of the change when environmental temperatures were elevated to near 42°C and to estimate TDC recovery time. The practical aspect of this research is motivated by the fact that patients in whom such measurements are made may arrive at the clinic in various states of sweat gland activation. Thus, knowledge of the effect of such activation on measured TDC values permits better understanding of possible relationships between such activation and TDC values. Results showed that increasing environmental temperature from 23·3 ± 1·6 to 41·5 ± 1·3°C increased forearm and thenar eminence skin temperatures to 37·8 ± 0·5 and 37·9 ± 0·4°C, respectively. These changes were associated with increases in TDC at arm from 30·7 ± 4·6 to 36·3 ± 5·7 (18·2%) and at hand from 34·7 ± 4·9 to 45·1 ± 5·5 (30%). Based on calculated TDC recovery rates, it is concluded that temperature-related TDC variability can be minimized using a wait time of at least 15 min after bandage removal prior to TDC measurements in affected limbs.
