RESUMEN

BACKGROUND: The coronavirus disease 2019 pandemic unleashed a flood of untrustworthy information on social media platforms, resulting in the unfortunate consequence of expert scientists' opinions getting lost amidst the chaotic sea of misinformation. The question of how much influence these esteemed scientists hold on social media platforms remains elusive. To address this scientific quandary, we sought to explore the concept of the Kardashian index (K-index), a term introduced by Hall in 2014. This metric provides a rudimentary means of evaluating whether a physician scientist's popularity on social media aligns with their significant scientific contributions. AIM: To evaluate if a Gastroenterologist physician's popularity on social media is at par with their scientific contributions (research articles and publications). METHODS: We conducted an extensive search to identify all gastroenterologists actively practicing and associated with the top 100 hospitals as reported by the United States News. We collected specific data on a sub-group including their names, affiliations, degrees, and sub-specializations. To gauge their social media popularity, we utilized the K-index calculation which is determined by dividing the actual number of Twitter followers by the number of researcher's citations. The expected number of followers (F) is calculated using the formula F = 43.3 C ^ 0.32, where C represents the number of citations. RESULTS: Physicians affiliated with the Mayo Clinic emerged as the most prominent presence on Twitter, constituting 16% of the total. They were followed closely by physicians from Mount Sinai Hospital (9%) and the University of Michigan Hospital (9%). Surprisingly, 76% of the physicians evaluated exhibited a low K-index, falling within the range of 0 to less than 2. This suggests that a significant number of highly influential physician-scientists are not receiving due recognition, as indicated by their relatively low number of followers. On the other hand, 24% of the physicians had an inflated K-index, exceeding 5, which positioned them as the "Kardashians". These individuals enjoyed greater social media popularity than their actual scientific contributions. Interestingly, our analysis revealed no discernible association between sex and K-index (P value of 0.92). CONCLUSION: In the gastroenterology field, our study estimated that a majority (76%) of highly researched physicians are undervalued despite their significant scientific contributions.

RESUMEN

(1) We investigated the involvement of serum magnesium level in early alcoholic liver disease (ALD), gut barrier dysfunction, and inflammation in alcohol use disorder (AUD) patients; and lastly, the efficacy of 2-week abstinence and medical management to alleviate hypomagnesemia. (2) Forty-eight heavy drinking AUD patients (34 males (M)/14 females (F)) participated in this study. Patients were grouped by serum alanine aminotransferase (ALT) level (a marker of liver injury) as group 1 (Group 1 (Gr.1); ALT ≤ 40 U/L, 7M/8F, without any indication of early-stage ALD) and group 2 (Group 2 (Gr.2); ALT > 40 U/L, 27M/6F or early-stage ALD). These patients were sub-divided within each group into patients with normal magnesium (0.85 and more mmol/L) and deficient magnesium (less than 0.85 mmol/L) levels. All participants were assessed at baseline (BL) and received standard medical management for 2 weeks with reassessment at the treatment end (2w). (3) Female participants of this study showed a significantly lower baseline level of magnesium than their male counterparts. Gr.2 patients showed a greater propensity in the necrotic type of liver cell death, who reported higher chronic and recent heavy drinking. Magnesium level improved to the normal range in Gr.2 post-treatment, especially in the hypomagnesemia sub-group (0.77 ± 0.06 mmol/L (BL) vs. 0.85 ± 0.05 mmol/L (2w), p = 0.02). In Gr.2, both apoptotic (K18M30) and necrotic (K18M65) responses were significantly and independently associated with inflammasome activity comprising of LBP (Lipopolysaccharide binding-protein) and TNFα (Tumor necrosis factor -α), along with serum magnesium. (4) In AUD patients with liver injury, 2-week medical management seems to improve magnesium to a normal level. This group exhibited inflammatory activity (LBP and TNFα) contributing to clinically significant hypomagnesemia. In this group, the level of magnesium, along with the unique inflammatory activity, seems to significantly predict apoptotic and necrotic types of hepatocyte death.

RESUMEN

Right aortic arch (RAA) with an aberrant left subclavian artery (LSA) is a very rare anatomical variant of the aorta, which is rarely symptomatic. However, symptoms may vary depending on the relationship of the aberrant subclavian artery to the surrounding structures. In this report, we present a case of an 8-year-old girl who was identified with Edward's type II RAA with LSA after developing a list of symptoms that led to the diagnosis of pulmonary sequestration, which in turn led to the discovery of her congenital aortic abnormality.

RESUMEN

Primary mediastinal large B-cell lymphoma (PMBCL) is an aggressive B-cell lymphoma arising from thymic B-cells having clinicopathologic features distinct from systemic diffuse large B-cell lymphoma (DLBCL). PMBCL comprises 2% to 4% of all non-Hodgkin lymphomas (NHL), 7% of DLBCL and seen predominantly in young females with a median age of 35 years at diagnosis. The annual incidence of PMBCL is 0.4 per million with a 5-year survival rate exceeding 70% with improving supportive care and genetic characterization of the disease. Pathogenesis involves dysregulation of Janus kinase-signal transducer and activator of transcription (JAK-STAT), nuclear factor-kB (NF-kB) pathways and amplification of the 9p24.1 region of chromosome 9. PMBCL patients have a prolonged life expectancy necessitating the need for treatment approaches that are based on maximizing cure with minimal long-term toxicity. Due to rarity and its recognition as a distinct entity, therapeutic decisions are guided by clinical presentation, clinician and center experience, and analysis of patients with PMBCL within DLBCL registries. Historically R-CHOP has been the usual first line treatment for PMBCL followed by involved site radiotherapy (ISRT), however clinical practice varies across centers with emerging consensus to avoid upfront RT by utilizing dose intense regimens (DA-EPOCH-R) in younger and fit patients. Prognosis of relapsed refractory PMBCL not responding to salvage chemotherapy is dismal, however there are many emerging options including Brentuximab Vedotin, immune check point inhibitors and chimeric antigen receptor T-cell therapy. In this article, we focus on the pathogenesis, current and evolving treatments, and provide recommendations for optimal management of patients with PMBCL.

RESUMEN

Background Since the first case of coronavirus disease-19 (COVID-19) in Pakistan was reported in February 2020, the medical and paramedical staff has been working on the frontlines to deal with this disease. They have been facing significant strain and stress due to the pandemic, affecting their social, mental, and personal life. The purpose of this study is to investigate the psychological effects of the COVID-19 pandemic, etiology, personal coping mechanisms, and the strategies that are being adopted to reduce stress by the healthcare workers (HCWs) working in COVID-19 dedicated wards (group 2) and compare it with staff working in other departments but not in COVID-19 wards amid this pandemic (group 1) in various hospitals of Lahore, Pakistan. Methods The comparative cross-sectional study was designed which included doctors, nurses, and allied health professionals from various hospitals of Lahore, Pakistan. A questionnaire was designed which consisted of five sections, and 51 questions. A Chi-square test was used to compare the responses between these two groups. Results The study questionnaire was submitted by 200 participants, 100 responses for each group (see the Appendix). In group 1, HCWs not working in COVID-19 dedicated floors were afraid of getting infected, transmitting the infection to their families and concerned about using personal protective equipment (PPE) improperly. They reported a lack of concentration and tense muscles. The coping mechanisms of this group were exercise, strict precautions at work, and social distancing measures. While HCWs serving in COVID-19 dedicated wards were concerned and afraid of putting their families at risk by working in the high-risk environment; the major stresses in this group were: lack of knowledge about proper strategies for treatment, they faced insecurity due to physical and verbal violence by caretakers of COVID-19 patients, and lack of concentration. The coping mechanism was the support of their families and taking strict precautions, with self-isolation if required, to avoid any disease transmission to their families. The proposed strategies to be implemented included teaching skills for self-rescue as well as the implementation of policies at the administrative level to reduce working hours and frequent shift rotation. Conclusion The COVID-19 outbreak posed a great deal of mental stress among HCWs working on the COVID-19 floor as well as those serving in other departments of the hospital. The HCWs from group 1 were most afraid of getting infected and putting family members at risk, experienced tense muscles and lack of concentration, coped their stress by exercise and being more vigilant, and suggested the strategies of teaching skills for self-rescue and better community awareness. While the staff from the second group were most afraid of being the source of infection and violence from the caretakers of patients, experienced tense muscles, used family support, and strict isolation measures as coping mechanisms and suggested the strategies of self-rescue and increase in wages of directly exposed healthcare workers to deal with such pandemics in future in a better way.
