Strategies for developing a successful career in academic medicine.

Academic medicine provides physicians an opportunity for long-term career satisfaction and fulfillment. However, despite the potential for great reward, academic careers can be challenging. To better define approaches to successfully navigate academic medicine, the Southern Society for Clinical Investigation sponsored a workshop titled 'Successful Careers in Academic Medicine' during the 2023 Southern Regional Meeting held in New Orleans; the critical elements of which are highlighted in the following summary.

Recent advances in personalized cancer immunotherapy with immune checkpoint inhibitors, T cells and vaccines.

The results of genomic and molecular profiling of cancer patients can be effectively applied to immunotherapy agents, including immune checkpoint inhibitors, to select the most appropriate treatment. In addition, accurate prediction of neoantigens facilitates the development of individualized cancer vaccines and T-cell therapy. This review summarizes the biomarker(s) predicting responses to immune checkpoint inhibitors and focuses on current strategies to identify and isolate neoantigen-reactive T cells as well as the clinical development of neoantigen-based therapeutics.

The Value of Liver Biopsy and Histology in Liver Disease Diagnosis and Patient Care-a Pragmatic Prospective Clinical Practice Study.

Goals: We aimed to examine the correlation of pre-biopsy clinical diagnosis with hepatic histopathology.

Background: Liver biopsy provides histologic information and informs physicians about the underlying clinical disease. We hypothesized that expert physicians' pre-biopsy clinical diagnoses may obviate the need for histopathological diagnosis.

Risk of Gastric Cancer is Highly Dependent on Type of First-Degree Family Member Affected by Cancer: Lessons from a High-Risk Population in Iran.

Background: Family history of gastric cancer (GC) in first-degree relatives may increase the risk of GC. This study aimed to assess how family history of GC in first-degree relatives really affects the risk of GC in an extremely high-risk population.

Methods: A large population-based case-control study was carried out on 1222 incident GC cases and 1235 controls in Ardabil Province-a high-risk area in North-West Iran-to assess the associations of GC family history in first-degree relatives with the risk of GC (2003-2017).

The diabetes cascade of care through the 14 years in Iran: findings of nationwide STEPS surveys 2007-2021.

Background: Diabetes as the leading cause of mortality and morbidity, have been increased by about 35% from 2011 to 2015 worldwide. The objective of this study was to assess the trend and pattern of diabetes and prediabetes prevalence in Iran and also evaluate the diagnosis and status of diabetes management.

Methods: The results of this study are extracted from the National Stepwise approach to non-communicable disease risk factor surveillance (STEPS), conducted in 2007, 2011, 2016, and 2021 in Iran.

Differential spatial distribution of HNF4α isoforms during dysplastic progression of intraductal papillary mucinous neoplasms of the pancreas.

Hepatocyte Nuclear Factor 4-alpha (HNF4α) comprises a nuclear receptor superfamily of ligand-dependent transcription factors that yields twelve isoforms in humans, classified into promoters P1 or P2-associated groups with specific functions. Alterations in HNF4α isoforms have been associated with tumorigenesis. However, the distribution of its isoforms during progression from dysplasia to malignancy has not been studied, nor has it yet been studied in intraductal papillary mucinous neoplasms, where both malignant and pre-malignant forms are routinely clinically identified.

Diagnostic utility of CT angiography compared with endoscopy in patients with acute GI hemorrhage.

Background And Aims: Because it is minimally invasive, CT angiography (CTA) has emerged as an attractive diagnostic tool for investigation of acute GI hemorrhage.

Methods: This study examined patients with acute GI bleeding who underwent CTA.

Results: CTA was the initial diagnostic examination in 177 patients, identifying upper and lower GI bleeding lesions in 16 and 27 patients, respectively.

Clinical application of circulating tumor DNA in metastatic cancers.

Introduction: Advances in genomics have facilitated the application of cell-free DNA (cfDNA) and circulating tumor DNA (ctDNA) in phase II and phase III clinical trials. The various mutations of cfDNA/ctDNA have been correlated with clinical features. Advances in next-generation sequencing (NGS) and digital droplet PCR have paved the way for identifying cfDNA/ctDNA mutations.

An Exploration of Some Predictors of Quality of Life-Related to the Innate Immune System, Inflammation, and Disease Activity in Patients with Behcet's Syndrome: An Analytical Cross-sectional Study.

Background: Behçet's disease (BD) has a growing prevalence in Silk Road countries. The aim of our cross-sectional study was to explore the clinical and molecular predictors of quality of life in BD patients.

Materials And Methods: One hundred and fifty consecutive Iranian BD patients with an age range between 20-50 years were included.

Paxillin regulates liver fibrosis via actin polymerization and ERK activation in hepatic stellate cells.

Liver injury leads to fibrosis and cirrhosis. The primary mechanism underlying the fibrogenic response is the activation of hepatic stellate cells (HSCs), which are 'quiescent' in normal liver but become 'activated' after injury by transdifferentiating into extracellular matrix (ECM)-secreting myofibroblasts. Given that integrins are important in HSC activation and fibrogenesis, we hypothesized that paxillin, a key downstream effector in integrin signaling, might be critical in the fibrosis pathway.

OLED catheters for inner-body phototherapy: A case of type 2 diabetes mellitus improved via duodenal photobiomodulation.

Phototherapeutics has shown promise in treating various diseases without surgical or drug interventions. However, it is challenging to use it in inner-body applications due to the limited light penetration depth through the skin. Therefore, we propose an organic light-emitting diode (OLED) catheter as an effective photobiomodulation (PBM) platform useful for tubular organs such as duodenums.

Human cytomegalovirus infection enhances 5‑lipoxygenase and cycloxygenase‑2 expression in colorectal cancer.

Colorectal cancer (CRC) is one of the most common and fatal types of cancer. Inflammation promotes CRC development, however, the underlying etiological factors are unknown. Human cytomegalovirus (HCMV), a virus that induces inflammation and other cancer hallmarks, has been detected in several types of malignancy, including CRC.

Global Effect of Modifiable Risk Factors on Cardiovascular Disease and Mortality.

Background: Five modifiable risk factors are associated with cardiovascular disease and death from any cause. Studies using individual-level data to evaluate the regional and sex-specific prevalence of the risk factors and their effect on these outcomes are lacking.

Methods: We pooled and harmonized individual-level data from 112 cohort studies conducted in 34 countries and 8 geographic regions participating in the Global Cardiovascular Risk Consortium.

Gastric troubles in Iran: The role of social and economic factors in infection.

Background: infection is a major risk factor for gastric cancer in Iran, but the impact of socioeconomic factors on its prevalence is poorly understood. This study aimed to assess the socioeconomic inequalities and risk factors associated with infection in Iran.

Methods: This cross-sectional study was conducted based on the PERSIAN cohort study.

The Effect of Topical Nifedipine versus Diltiazem on the Acute Anal Fissure: A Randomized Clinical Trial.

The anal fissure is one of the most common anorectal diseases that is associated with reduced quality of life and productivity loss. We aimed to compare the efficacy of topical nifedipine and diltiazem for the treatment of acute anal fissure (AAF). This single-blind randomized clinical trial was conducted at Ziaeian hospital, Tehran.

Prevalence and Correlates of Polypharmacy, and Drug Utilization Pattern in a Semi-urban Population: Results from the Pars Cohort Study.

We aimed to indicate the prevalence and correlates of polypharmacy and to determine the medication profile at the population level in southern Iran.

Methods: In this cross-sectional study, we analyzed data from participants of the Pars Cohort Study (PCS) (aged above 40 years, N=9269).

Potential of Autologous Adipose-Derived Mesenchymal Stem Cells in Peritoneal Fibrosis: A Pilot Study.

Background: We aimed to determine the effects of systemic therapy with autologous adipose tissue derived mesenchymal stem cells (AD-MSCs) on different parameters of peritoneal function and inflammation in peritoneal dialysis (PD) patients.

Methods: We enrolled nine PD patients with ultrafiltration failure (UFF). Patients received 1.

The impact of prior performance information on subsequent assessment: is there evidence of retaliation in an anonymous multisource assessment system?

Few studies have engaged in data-driven investigations of the presence, or frequency, of what could be considered retaliatory assessor behaviour in Multi-source Feedback (MSF) systems. In this study, authors explored how assessors scored others if, before assessing others, they received their own assessment score. The authors examined assessments from an established MSF system in which all clinical team members - medical students, interns, residents, fellows, and supervisors - anonymously assessed each other.
