Internal Medicine Residents’ Perceptions of Virtual Morning Report: a Multicenter Survey

ImportanceThe COVID-19 pandemic disrupted graduate medical education, compelling training programs to abruptly transition to virtual educational formats despite minimal experience or proficiency. We surveyed residents from a national sample of internal medicine (IM) residency programs to describe their experiences with the transition to virtual morning report (MR), a highly valued core educational conference.ObjectiveAssess resident views about virtual MR content and teaching strategies during the COVID-19 pandemic.DesignAnonymous, web-based survey.ParticipantsResidents from 14 academically affiliated IM residency programs.Main MeasuresThe 25-item survey on virtual MR included questions on demographics; frequency and reason for attending; opinions on who should attend and teach; how the virtual format affects the learning environment; how virtual MR compares to in-person MR with regard to participation, engagement, and overall education; and whether virtual MR should continue after in-person conferences can safely resume. The survey included a combination of Likert-style, multiple option, and open-ended questions.ResultsSix hundred fifteen residents (35%) completed the survey, with a balanced sample of interns (39%), second-year (31%), and third-year (30%) residents. When comparing their overall assessment of in-person and virtual MR formats, 42% of residents preferred in-person, 18% preferred virtual, and 40% felt they were equivalent. Most respondents endorsed better peer-engagement, camaraderie, and group participation with in-person MR. Chat boxes, video participation, audience response systems, and smart boards/tablets enhanced respondents’ educational experience during virtual MR. Most respondents (72%) felt that the option of virtual MR should continue when it is safe to resume in-person conferences.ConclusionsVirtual MR was a valued alternative to traditional in-person MR during the COVID-19 pandemic. Residents feel that the virtual platform offers unique educational benefits independent of and in conjunction with in-person conferences. Residents support the integration of a virtual platform into the delivery of MR in the future.Supplementary InformationThe online version contains supplementary material available at 10.1007/s11606-021-06963-7.KEY WORDS: graduate medical education, internal medicine residency, morning report, virtual     

Newer variants of progressive familial intrahepatic cholestasis

Progressive familial intrahepatic cholestasis (PFIC) is a heterogeneous group of disorders characterized by defects in bile secretion and presentation with intrahepatic cholestasis in infancy or childhood. The most common types include PFIC 1 (deficiency of FIC1 protein, ATP8B1 gene mutation), PFIC 2 (bile salt export pump deficiency, ABCB11 gene mutation), and PFIC 3 (multidrug resistance protein-3 deficiency, ABCB4 gene mutation). Mutational analysis of subjects with normal gamma-glutamyl transferase cholestasis of unknown etiology has led to the identification of newer variants of PFIC, known as PFIC 4, 5, and MYO5B related (sometimes known as PFIC 6). PFIC 4 is caused by the loss of function of tight junction protein 2 (TJP2) and PFIC 5 is due to NR1H4 mutation causing Farnesoid X receptor deficiency. MYO5B gene mutation causes microvillous inclusion disease (MVID) and is also associated with isolated cholestasis. Children with TJP2 related cholestasis (PFIC-4) have a variable spectrum of presentation. Some have a self-limiting disease, while others have progressive liver disease with an increased risk of hepatocellular carcinoma. Hence, frequent surveillance for hepatocellular carcinoma is recommended from infancy. PFIC-5 patients usually have rapidly progressive liver disease with early onset coagulopathy, high alpha-fetoprotein and ultimately require a liver transplant. Subjects with MYO5 B-related disease can present with isolated cholestasis or cholestasis with intractable diarrhea (MVID). These children are at risk of worsening cholestasis post intestinal transplant (IT) for MVID, hence combined intestinal and liver transplant or IT with biliary diversion is preferred. Immunohistochemistry can differentiate most of the variants of PFIC but confirmation requires genetic analysis.     

Deep insight into white spot syndrome virus vaccines: A review

White spot syndrome virus (WSSV), the causative virus of the disease, is found in most shrimp farming areas of the world, where it causes large economic losses to the shrimp farming industry. The potentially fatal virus has been found to be a threat not only to all shrimp species, but also to other marine and freshwater crustaceans, such as crab and crayfish. To date, no effective prophylactic treatment measures are available for viral infections in shrimp and other crustaceans. Due to current aquaculture practices and the broad host range of WSSV, intervention strategies including vaccination against this virus would be pivotal to save and protect shrimp farming. Several achievements have been attained in the search of novel vaccines for WSSV. DNA vaccination, recombinant vaccines, oral vaccination techniques and gene therapy are some of the thrust areas of focus for scientists and researchers. This review article highlights the recent trends in the development of WSSV vaccines either as DNA vaccines or recombinant vaccines and their functioning strategies as suggested by the researchers worldwide.     

The neuroprotective efficacy of alpha-crystallin against acute inflammation in mice

Acute inflammation activates macrophages or monocytes and subsequently releases several inflammatory cytokines and reactive oxygen and nitrogen species. These proinflammatory cytokines activate astrocytes and trigger neurodegenerative diseases. In this work, we chose to address the mechanistic aspects of alpha-crystallin's protective function in inflammation-triggered neurotoxicity in mice. Alpha-crystallin, a lens structural protein, comprising alpha-A and alpha-B subunits is an ubiquitous molecular chaperone, which have been shown to reduce reactive oxygen species (ROS) production and enhance cellular glutathione level in the acute inflammation-induced mice. Results show that the proinflammatory cytokines such as interleukin-1alpha (IL-1alpha) and tumor necrosis factor-alpha (TNF-alpha) and nitric oxide (NO) were significantly high (P<0.05) in the plasma, liver, cortex and hippocampus of inflammation-induced mice when compared to control. Alpha-crystallin pretreatment prevents inflammation-induced cytokines and NO production. In addition, a significant (P<0.05) reduction of dopamine (DA), 5-hydroxytryptamine (5-HT) and norepinephrine (NE) was also observed in the inflammation-induced mice. Nevertheless, their metabolites, such as 3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA) and 5-hydroxyindole acetic acid (5-HIAA) increased significantly (P<0.05) as compared to control. The results indicate that alpha-crystallin pretreatment controls the inflammation-induced DA, 5-HT and NE catabolism and suggest that alpha-crystallin has the potential to act as an anti-inflammatory agent in the neuroprotective processes.     

Epidemiological studies on pulmonary pathogens in HIV-positive and -negative subjects with or without community-acquired pneumonia with special emphasis on Mycoplasma pneumoniae

The prevalence of Mycoplasma pneumoniae among HIV-positive patients with community-acquired pneumonia (CAP) remains unclear. We investigated 300 HIV-positive adults (200 with CAP and 100 with no respiratory illness) and 75 HIV-negative adults with CAP for the prevalence of respiratory pathogens using culture and serology. A growth inhibition test was employed to confirm the isolates of M. pneumoniae using species-specific typing sera. The prevalence of M. pneumoniae in HIV-positive subjects was 17% by induced sputum and 11.3% by throat swab culture. The seroprevalence of anti-M. pneumoniae IgM was 11.7% by ELISA and 14.3% by the gelatin microparticle agglutination test. The prevalence of M. pneumoniae among HIV-negative cases was relatively low. Streptococcus pneumoniae was predominant (28%) among subjects with lower respiratory disease, whereas Staphylococcus aureus (15%) was common among upper respiratory symptomatic cases. Rales (P=0.001), pharyngeal erythema (P=0.02), cervical adenopathy (P=0.004), skin rash (P=0.001), and crepitations (P=0.001) were each significantly related to M. pneumoniae positivity. Statistical significance was observed in relation to total lymphocyte count (P=0.02) and erythrocyte sedimentation rate (P=0.04), as well as M. pneumoniae positivity. This study shows that the prevalence of M. pneumoniae in HIV-positive subjects is comparatively higher than in HIV-negative subjects with pulmonary symptoms, and concords with previous pilot studies carried out in Chennai, South India.     

The association of salvage intravesical therapy following BCG with pathologic outcomes and survival after radical cystectomy for patients with high-grade non-muscle invasive bladder cancer: A multi-institution analysis

IntroductionWhile numerous current clinical trials are testing novel salvage therapies (ST) for patients with recurrent nonmuscle invasive bladder cancer (NMIBC) after bacillus Calmette-Guérin (BCG), the natural history of this disease state has been poorly defined to date. Herein, we evaluated oncologic outcomes in patients previously treated with BCG and ST who subsequently underwent radical cystectomy (RC).MethodsWe identified 378 patients with high-grade NMIBC who received at least one complete induction course of BCG (n = 378) with (n = 62) or without (n = 316) additional ST and who then underwent RC between 2000 and 2018. Oncologic outcomes were compared using the Kaplan-Meier method and Cox proportional hazards models. Sensitivity analyses were conducted stratifying by presenting tumor stage, matched 1:3 for receipt vs. no receipt of ST.ResultsPatients receiving ST were more likely to initially present with CIS (26% vs. 17%) and less likely with T1 disease (34% vs. 50%, P = 0.06) compared to patients not treated with ST. Receipt of ST was not associated with increased risk of adverse pathology (≥pT2 or pN+) at RC (31% vs. 41%, P = 0.14). Likewise, 5-year cancer-specific survival did not significantly differ between groups on univariable Kaplan-Meier analysis (73% for ST and 74% for no ST, P = 0.7). Moreover, on multivariable analysis, receipt of ST was not significantly associated the risk of death from bladder cancer (HR 1.12; 95% CI 0.60–2.09, P = 0.7). Results were unchanged on sensitivity analysis.ConclusionsThese data suggest that, in carefully selected patients, ST following BCG for high grade NMIBC does not compromise oncologic outcomes for patients who ultimately undergo RC.     

Acute abdomen due to eosinophilic colitis with liver abscess.

Eosinophilic colitis is an uncommon condition and rarely presents as acute abdomen. We report a 65-year-old man who presented with acute abdomen-- severe pain in upper abdomen, with pyrexia, tachycardia, guarding and right-sided intercostal tenderness--secondary to eosinophilic colitis and was successfully managed. He had additional problems in form of cirrhosis, chronic hepatitis, cholangitis, pyogenic liver abscesses and gout.
