Levothyroxine Requirement In A Patient With Lrba Deficiency And Gvhd Induced Cholestasis, Yusriya Al Rawahi, Hussain Alsaffar, Amr Abdalla, Azza Nasser Al Shidhani

Sultan Qaboos University Medical Journal

Levothyroxine is a lipophilic hormone that is absorbed in the small intestine, mainly in the jejunum and ileum. The absorption of levothyroxine after oral administration averages 60–80%. We report a 7-year-old male patient who presented to a tertiary care hospital in Muscat, Oman, in 2020 at the age of three years with an early diagnosis of lipopolysaccharide beige-like anchor protein (LRBA) deficiency. LRBA deficiency is characterised by recurrent infections, autoimmune thyroid disease and autoimmune cytopenia. The patient was prescribed levothyroxine treatment (112.5 mcg daily) and underwent haematopoietic stem cell transplantation (HSCT) in March 2023; four months post-HSCT, he developed appendicitis …

From Er To Mortality In 48 Hours: A Fatal Case Of Overwhelming Post-Splenectomy Infection, Miriam Stern, Ba, Blaise O’Malley, Bs, Amry Majeed, Md, Michael Grodsky, Md

The Medicine Forum

Overwhelming post-splenectomy infection (OPSI) is a known complication of asplenia.1,2 While the precise rates of morbidity and mortality are unknown, estimates range from 38% to as high as 70%.2 Because the spleen plays an important role in protecting against infections with encapsulated microorganisms, OPSI is most commonly caused by infection with encapsulated bacteria, specifically Streptococcus pneumoniae.1–3 While pneumococcal vaccines have been shown to improve immunogenicity in asplenic people, OPSI remains a danger to both vaccinated and unvaccinated patients.4,5 Additional measures to protect asplenic patients from overwhelming infection have been proposed, but the evidence remains mixed. …


Case Report Of Gastritis As A Complication Of Immunotherapy Treatment Of Metastatic Endometrial Cancer With Lenvatinib And Pembrolizumab, Bret Mccarty, Md, Nia Johnson, Bs, Suchit Bhutani, Md Jun 2025

Case Report Of Gastritis As A Complication Of Immunotherapy Treatment Of Metastatic Endometrial Cancer With Lenvatinib And Pembrolizumab, Bret Mccarty, Md, Nia Johnson, Bs, Suchit Bhutani, Md

The Medicine Forum

Immune checkpoint inhibitors (ICIs), such as pembrolizumab (a PD-1 inhibitor), have been shown to be effective in the treatment of a variety of malignancies, including progressive endometrial cancer. ICIs help to activate the patient’s immune system to attack neoplastic cells. However, this immune activation can trigger autoimmune side effects throughout the body, known as immune-related adverse events (irAEs). Immunotherapyassociated hepatitis, colitis and diarrhea have been well documented as irAEs, but gastritis is much less common.1 In this case report of immunotherapy-related gastritis, we attempted to better characterize this more rare condition to assist with early recognition and initiation of appropriate …

Racial Disparities In Response To Ibd Directed Therapy In Crohn’S Disease And Ulcerative Colitis: A Single Center Experience, Ananya Venkatesh, Md, Justin Robbins, Md, Zach Breslin, Md, Cuckoo Choudhary, Md

The Medicine Forum

Crohn’s disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases (IBD) associated with significant morbidity and mortality. Current clinical guidelines recommend a range of therapies, including tumor necrosis factor alpha (TNFα) antagonists, anti-integrins, interleukin-12/23 (IL12/23) inhibitors, Janus kinase (JAK) inhibitors, and/or corticosteroids for both induction and maintenance of remission. Determining the optimal medication for individual patients can be challenging due to the complexity of treatment options and the need to consider numerous phenotypic factors. While treatment guidelines do not address racial differences explicitly, prior research has highlighted significant phenotypic disparities based on race. This study aims to explore …

Microglial Phagocytosis In Epilepsy: Mechanisms And Impact, Abhijeet S Barath, Long-Jun Wu Jun 2025

Microglial Phagocytosis In Epilepsy: Mechanisms And Impact, Abhijeet S Barath, Long-Jun Wu

The Brown Foundation: Institute of Molecular Medicine

Microglia are resident immune cells critical in maintaining brain homeostasis via their surveillance and phagocytosis function. Under disease contexts such as seizures and epilepsy, microglial phagocytic signalling is activated in response to both inflammatory and non-inflammatory cell death. This process involves a range of well-characterized 'find me' and 'eat me' signals, phagocytic receptors, and less well-characterized intracellular signalling pathways. In addition, epigenetic and transcriptional regulators orchestrate microglial responses to seizures, including the integration of phagocytic and inflammatory pathways. Interestingly, although inhibiting phagocytosis has been shown to improve neuronal survival and cognitive performance after seizures, it paradoxically increases the risk of …

Hypoxia-inducible factors (HIFs) promote lung protection and pathogen eradication during acute lung injury. We therefore tested the theory that pharmacologic stabilization of HIFs dampens lung injury during SARS-CoV-2 pneumonia. Initial studies in murine SARS-CoV-2 models showed improved outcomes after treatment with the FDA-approved HIF-stabilizer vadadustat. Subsequent studies in genetic models implicated alveolar-expressed Hif1a in mediating lung protection. Therefore, we performed a randomized, double-blinded, multicenter phase 2 trial in patients admitted for SARS-CoV-2 infection and concomitant hypoxia (SpO2 ≤ 94%). Patients (n=448) were randomized to oral vadadustat (900 mg/day) or placebo for up to 14 days. Safety events were similar between …

Proteogenomic analysis is applied to samples from the CALGB 40601 (Alliance) randomized neoadjuvant trial of trastuzumab, lapatinib, or the combination to identify biomarkers associated with pathological response status. Absence of ERBB2 gene amplification and human epidermal growth factor receptor 2 (HER2) protein overexpression by proteogenomics is associated with non-pathological compete response (pCR) (p < 0.05), highlighting potential false positives from standard diagnostics. Pathway analysis in proteogenomics-confirmed HER2+ samples identifies elevated epithelial-mesenchymal transition (EMT) and WNT-β-catenin signaling in non-pCR cases before treatment. Twenty-four pCR-associated proteins reproduce in a second proteomic dataset, and four (GPRC5A, TPBG, SP140L, and NEU1) are significant in a third. A meta-analysis of ten diverse neoadjuvant anti-HER2 treatment regimens from four independent studies confirms that non-pCR cases express higher levels of mRNA for G protein-coupled receptor class C group 5 member A (GPRC5A, p = 0.0002) and trophoblast glycoprotein (TPBG, p = 0.00008). Thus, proteogenomic analysis identifies negative biomarkers for pCR and alternative plasma membrane targets for treatment-resistant HER2+ breast cancer.

Human norovirus is the leading cause of viral gastroenteritis across all age groups. While there is a need for human norovirus antivirals, therapeutic development has been hindered by a lack of cell culture systems and animal models of infection. Surrogate viruses, such as Tulane virus (TV), have provided tractable systems to screen potential antiviral compounds. Our previous work demonstrated that TV encodes a viral ion channel, which dysregulates cytosolic calcium signaling. We set out to investigate whether host pathways triggered by viral ion channel activity, including store-operated calcium entry (SOCE), play a role in virus replication. Using pharmacologic inhibitors and …

Advances In Molecular Imaging For Neuroendocrine Neoplasms, Bradley Girod, Vikas Prasad

2020-Current year OA Pubs

Neuroendocrine neoplasms (NENs) represent a heterogenous group of tumors with significant inter- and intra-patient variability. Once considered to be rare, neuroendocrine neoplasms are being increasingly recognized through the advent of advanced diagnostic techniques, which may be contributing to the significant increase in the incidence and detection rate of these tumors. NENs can be classified into well differentiated and poorly differentiated neuroendocrine tumors (NETs) or neuroendocrine carcinomas (NECs). The proliferation rate of NETs can vary from Ki-67 1-55%. In addition, the SSTR expression can vary significantly. Because of this high "heterogeneity", their detection and characterization have become essential to disease management, …

Sars-Cov-2 Nsp15 Enhances Viral Virulence By Subverting Host Antiviral Defenses, Allen Caobi, Tamarand L Darling, Adrianus C M Boon, Et Al.

2020-Current year OA Pubs

SARS-CoV-2 encodes numerous virulence factors, yet their precise mechanisms of action remain unknown. We provide evidence that the SARS-CoV-2 nonstructural protein 15 (nsp15) enhances viral virulence by suppressing the production of viral double-stranded (dsRNA), a potent inducer of antiviral signaling. The viral variants lacking nsp15 endoribonuclease activity elicited higher innate immune responses and exhibited reduced replication in human stem cell-derived lung alveolar type II epithelial cells, as well as in the lungs of infected hamsters. Consistently, these variants caused significantly less weight loss and mortality compared to wild-type (WT) virus in K18-hACE2 mice. Mechanistically, the cells infected with nsp15 mutants …

Sports And Physical Activity Of Poles In The Context Of Good Health And Well-Being As A Sustainable Development Goal, Elżbieta Biernat, Monika Piątkowska, Robert Podstawski Jun 2025

Sports And Physical Activity Of Poles In The Context Of Good Health And Well-Being As A Sustainable Development Goal, Elżbieta Biernat, Monika Piątkowska, Robert Podstawski

Baltic Journal of Health and Physical Activity

Investing in physical activity (PA) is vital for achieving sustainable development goals. We examine PA trends in Poland using data from Eurobarometer surveys conducted in 2013, 2017, and 2022. In 2022, 64.6% of Poles did not participate in sports, and 41.8% did not engage in non-sport PA. There is a concerning trend of increasing inactivity in sports (Chi22022/2017 = 34.64; p < 0.001; Chi22017/2013 = 56.98; p < 0.001) and non-sports PA (Chi22022/2017 = 18.3, p < 0.01 and Chi22017/2013 = 16.95, p < 0.01). Participation in sport and PA is influenced by individual, inter-personal, environmental, political, and global factors. Notably, there is an upward trend in interpersonal (e.g., club membership, volunteering), environmental (e.g., PA in parks/nature, at home), and political (e.g., dissatisfaction with local government actions) factors. Government intervention is crucial and requires: (1) establishment of an institution for leadership and advocacy of PA, (2) adoption of a cross-sectoral approach for a coordinated change, and (3) increased in-vestment in monitoring systems to track the impact of interventions. These actions are essential for fostering a more active and healthier population in Poland.


Psycho-Analysis Will Not Save Us: Reflections On The Gen Z Mental Health Crisis, Victor Dubitans Jun 2025

Psycho-Analysis Will Not Save Us: Reflections On The Gen Z Mental Health Crisis, Victor Dubitans

Middle Voices

Generation Z (born between 1997 – 2012) is characterized as having both unprecedented mental health awareness and unprecedented mental distress. An apparent contradiction with troubling implications for the mental health field: Either the response to the mounting crisis has been insufficient or the field forms part of the problem. Taking seriously Wilks’ (2023) criticism of “therapeutic overreach” of the contemporary mental health field in the lives and development of youth, this paper attempts a selfanalysis and moral inventory about the field’s potential complicity in the crisis and in the history of hysteria. Lacan’s writings on the “analyst’s discourse” are considered …

There is an urgent need for the design and development of new and safer drugs for the treatment of (Blood coagulation). New derivatives of furan-2-qoinoline as anti-coagulation drug bearing furan, quinolone, were synthesized with the aim of developing new drug inhibitors (Factor Xa enzyme) respectively. In our study, synthesis of the new organic compounds derived from Furo-2-quinolone substituted by treated with ammonia derivatives like hydrazine, give K6, and (1-Amino-4,6-dimethyl furo[3,2-g] quinoline-2-one) K6 then react with Formaldehyde to form K6a. And evaluated their effects on coagulation in the docking (MCULE). then compared this compound, with the Rivaroxaban. compound give the result …
