Many national meetings and speaker series feature an "Annual Review of the Literature" (ARL) session in which an individual or team presents a sampling of articles, selected and prepared because they represent important current topics or new ideas in the discipline of interest. Despite this, there is little in the medical literature describing how to thoughtfully and systematically develop these sessions. We identify best practices that we have developed and used in the United States Clerkship Directors of Internal Medicine (CDIM) over many years.

Background: Sinusoidal obstruction syndrome (SOS)/veno-occlusive disease (VOD) is generally associated with hematopoietic cell transplant (HCT), but little is known about this condition outside the HCT setting. This systematic review examines the burden of illness and current management approaches in non-HCT SOS/VOD.

Methods: We searched Embase, Medline, and grey literature sources for non-HCT SOS/VOD studies published 2002-2023.

Background & Objective: Blood Stream Infections (BSI) are considered a significant cause of morbidity and mortality in patients with Stevens Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN). We aimed to identify risk factors for BSI upon admission, highlight clinical and microbiological findings and ascertain the frequency of mortality in patients with BSI in SJS/TEN.

Methods: A retrospective cross-sectional study over 12 years (2011-2022) was performed in the department of medicine at a tertiary care hospital in Pakistan.

: Ocular predominant mucous membrane pemphigoid (oMMP) is a severe subtype of autoimmune blistering disease (AIBD), which can result in scarring and vision loss. The diagnosis of oMMP is challenging as patients often have undetectable levels of circulating autoantibodies by conventional assays. Likewise, the principal autoantigen in oMMP has been an area of debate.

Unlabelled: While autoantibodies in bullous pemphigoid (BP) are known to activate the innate immune response, their direct effect on keratinocytes, and the contribution of BP-IgG autoantibody-dependent keratinocyte responses to BP pathology is largely unknown. Herein, we performed multiplex immunoassays and bulk RNA-seq on primary keratinocytes treated with IgG from BP patients or controls. We identified a pro-inflammatory and proteolytic response with release of several cytokines (IL-6, IL-24, TGF-β1), chemokines (CXCL16, CTACK, MIP-3β, RANTES), C1s, DPP4, and MMP-9.

A 57-year-old woman on leflunomide with a history of chronic obstructive pulmonary disease and rheumatoid arthritis presented with multiple flesh-colored to hyperpigmented dome-shaped papules, scattered comedones, and underlying scarring on bilateral cheeks and chin. These dermatologic manifestations, laboratory evaluation, and punch biopsy led to a final diagnosis of acneiform or comedonal discoid lupus erythematosus (ACDLE). For patients with acneiform or comedonal lesions, ACDLE should be considered if the lesions do not improve with conventional treatment for acne vulgaris.

Given its relevance across numerous fields, reductive amination is one of the oldest and most widely used methods for amine synthesis. As a cornerstone of synthetic chemistry, it has largely remained unchanged since its discovery over a century ago. Herein, we report the mechanistically driven development of a complementary reaction, which reductively aminates the C-C σ-bond of carbonyls, not the carbonyl C-O π-bond, generating value-added linear and cyclic 3° amines in a modular fashion.

Persistent breast cancer treatment-related pain affects up to 40% of patients, decreasing their quality of life (QoL). While current research typically utilizes correlation and regression analysis to identify biopsychosocial phenotypes contributing to this pain, this study employs cluster analysis to identify qualitatively different phenotypes based on somatosensory and psychosocial characteristics both before and one week post-breast cancer surgery. Further, it investigates how these phenotypes are related to pain intensity one year post-surgery and examines the evolution of phenotype membership from pre- to post-surgery.

Acute myocardial infarction (AMI) is a serious medical condition generally known as heart attack, which is caused by the decreased or completely blocked blood flow to a part of the heart muscle. It is a significant cause of both mortality and morbidity throughout the world. Cardiac troponin-I (cTnI) is an important biomarker at different stages of AMI and is one of the most specific and widely used cardiac skeletal muscle proteins.

Article Synopsis
  • Ocular predominant mucous membrane pemphigoid (oMMP) is a severe condition that can lead to scarring and blindness; diagnosing it is challenging due to a high false-negative rate (up to 40%) in conjunctival biopsies that use direct immunofluorescence (DIF).
  • Serologic testing offers a less invasive diagnostic method but often shows low levels of autoantibodies in oMMP patients, making it less reliable.
  • The autoantigens involved, like integrin β4 and BP180, have shown mixed results in their specificity for diagnosing oMMP, prompting a need for better understanding and improvement in serological diagnostic approaches.

Xylanases are essential hydrolytic enzymes which break down the plant cell wall polysaccharide, xylan composed of D-xylose monomers. Surface-enhanced Raman Spectroscopy (SERS) was utilized for the characterization of interaction of xylanases with xylan at varying concentrations. The study focuses on the application of SERS for the characterization of enzymatic activity of xylanases causing hydrolysis of Xylan substrate with increase in its concentration which is substrate for this enzyme in the range of 0.

Article Synopsis
  • - Veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is a serious complication after hematopoietic cell transplantation (HCT), and early treatment can improve patient outcomes, but diagnosis is difficult due to overlapping symptoms with other issues post-transplant.
  • - The study aimed to validate "VODCheck," a biomarker-based test designed to predict VOD/SOS risk using three key biomarkers: hyaluronan (HA), angiopoietin-2 (ANG-2), and thrombomodulin (TM).
  • - Results showed that VODCheck accurately predicted VOD/SOS risk at multiple time points post-HCT, demonstrating its effectiveness as an independent risk predictor and providing valuable insights for better

In this study, Gordonia sp. HS126-4N was employed for dibenzothiophene (DBT) biodesulfurization, tracked over 9 days using SERS. During the initial lag phase, no significant spectral changes were observed, but after 48 h, elevated metabolic activity was evident.

  • Cutis verticis gyrata (CVG) is a rare skin condition featuring ridges and furrows on the scalp, categorized into primary essential, primary nonessential, and secondary types.
  • The case focuses on primary essential CVG, where a significant portion of the scalp and forehead was affected, requiring flap advancement after skin expansion for treatment.
  • This successful technique not only covers the skin defect and preserves hair growth but also leads to excellent cosmetic results, enhancing both the appearance and psychosocial well-being of the patient.

  • - Raman spectroscopy is utilized to analyze body fluids like blood serum for early breast cancer diagnosis by separating low molecular weight (LMWF) proteins from high molecular weight (HMWF) proteins using 30 kDa centrifugal filters.
  • - The filtrate from blood serum samples is expected to contain crucial breast cancer biomarkers, which are then examined using Surface Enhanced Raman Spectroscopy (SERS) to detect spectral characteristics linked to different stages of breast cancer.
  • - Using statistical methods like Principal Component Analysis (PCA) and Partial Least Discriminant Analysis (PLS-DA), the study achieved 79% accuracy, 76% specificity, and 81% sensitivity in distinguishing between cancerous and non-cancerous samples, indicating

In recent years, microRNAs (miRNAs) have emerged as key players in the pathophysiology of multiple diseases including Alzheimer's disease (AD). Messenger RNA (mRNA) targeting for regulation of gene expression by miRNAs has been implicated in the annotation of disease pathophysiology as well as in the explication of their starring role in contemporary therapeutic interventions. One such miRNA is miR-153 which mediates the survival of cortical neurons and inhibits plaque formation.

Sarcoidosis is notorious for producing a wide variety of skin lesions, which are categorized as either specific or nonspecific. The specific lesions include primary morphologies ranging from micropapules to subcutaneous nodules. Nonspecific skin lesions include associated conditions like erythema nodosum, calcinosis cutis, and prurigo.
