Objective: To characterize the performance of titanium mesh (TM) (off-label) for rigid chest wall reconstruction at a single institution over a 5-year period.

Methods: Between January 1, 2019, and May 15, 2023, 22 patients (median age, 61 years) underwent chest wall resection with TM reconstruction at Cleveland Clinic. Indications for resection included sarcoma (n = 15), breast cancer (n = 2), lung cancer (n = 2), chondroblastoma (n = 1), and benign neoplasm (n = 2).

Article Synopsis
  • The study introduces the esophageal length-to-height ratio (LHR) to measure the tortuosity of the esophagus in patients with achalasia, aiming to relate it to preoperative characteristics and post-surgery outcomes.
  • Over 400 adult patients underwent myotomy, and the LHR was calculated pre- and postoperatively, revealing that higher LHR was associated with poorer outcomes in symptom relief and esophageal emptying.
  • The findings indicate that LHR is a strong predictor of postoperative success, while the manometric subtype had a lesser impact on patient outcomes, showcasing a need for more tailored assessments in achalasia treatment.

Background: The COVID-19 pandemic has had a profound impact on surgical training globally. We aimed to explore and identify the specific challenges faced by women surgeons during the pandemic and provide recommendations for improvement.

Methods: A survey was conducted among trainee members of the Association of Women Surgeons, assessing various aspects of clinical training, mental well-being, and personal and professional life.

The dynamic evolution of the severe acute respiratory syndrome coronavirus 2 virus is primarily driven by mutations in its genetic sequence, culminating in the emergence of variants with increased capability to evade host immune responses. Accurate prediction of such mutations is fundamental in mitigating pandemic spread and developing effective control measures. This study introduces a robust and interpretable deep-learning approach called PRIEST.

The diaphragm is a musculoaponeurotic structure separating the thoracic and abdominal cavities. It plays important roles in both respiration and maintaining gastrointestinal function. A careful consideration of anatomy should be taken during surgical procedures to minimize injury to this crucial organ.

Background: Inaccuracy of clinical staging renders management of clinical T2 N0 M0 (cT2 N0 M0) esophageal cancer difficult. When an underlying advanced-stage disease is understaged to cT2 N0 M0, patients miss the opportunity to gain the potential benefits of neoadjuvant therapy. This study aimed to identify preoperative factors that predict underlying advanced-stage esophageal cancer.

Background: Open approaches for esophagectomy are often still useful; of these, left thoracoabdominal esophagectomy (TAE) is poorly understood and often criticized. Hence, we examined TAE's worldwide utilization, survival, and present-day use and outcomes at our institution compared with contemporary national averages.

Methods: The Worldwide Esophageal Cancer Collaboration database includes 8854 patients who underwent esophagectomy for cancer between 2005 and 2014, a period when TAE was our center's most common approach.

Objective: Spread through air spaces (STAS) is a new histologic feature of invasion of non-small cell lung cancer that lacks sensitivity and specificity on frozen sections and is associated with higher recurrence and worse survival with sublobar resections. Our objective is to identify preoperative characteristics that are predictive of STAS to guide operative decisions.

Methods: From January 2018 through December 2021, 439 cT1-3N0 M0 patients with non-small cell lung cancer and a median age of 68 years, 255 (58%) women, who underwent primary surgery at our institution were included.

Objectives: We hypothesized that emergency complications related to asymptomatic paraconduit hernias may occur less often than generally believed. Therefore, we assessed the occurrence and timing of paraconduit hernia diagnosis after esophagectomy, as well as outcomes of these asymptomatic patients managed with a watch-and-wait approach.

Methods: From 2006 to 2021, 1214 patients underwent esophagectomy with reconstruction at the Cleveland Clinic.

Objective: Currently, there is no validated patient-reported outcome measure (PROM) applicable to all esophageal diseases. Our objective was to create a psychometrically robust, validated universal esophageal PROM that can also objectively assess patients' quality of life (QoL).

Methods: The pilot PROM constructed based on expert opinions, literature review, and previous unpublished institutional research had 27 items covering 8 domains.

Background: Esophageal morphology in achalasia is thought to affect outcomes, with "end-stage" sigmoidal morphology faring poorly; however, evaluation of morphology's role in outcomes has been limited by lack of objective characterization. Hence, the goals of this study were twofold: characterize the variability of timed barium esophagram (TBE) interpretation and evaluate an objective classification of TBE tortuosity: length-to-height ratio (LHR). We hypothesized that the esophagus must elongate to become sigmoidal such that sigmoidal morphology would demonstrate a larger LHR.

Background: Type I achalasia comprises 20% of achalasia and has nearly absent esophageal motor activity. Concerns that fundoplication decreases the effectiveness of Heller myotomy in these patients has increased adoption of peroral endoscopic myotomy (POEM). Hence, we compared outcomes after Heller myotomy with Dor fundoplication vs POEM.

Approaches to achalasia include non-operative and operative techniques with Heller Myotomy and Per-Oral Endoscopic Myotomy (POEM) at the forefront of palliative strategies. Given the diverse subtypes and the time-dependent failure pattern for achalasia, there is no standard approach. We elect for a POEM for type III achalasia, poor functional status, hostile abdomen, and salvage after the previous myotomy.

Article Synopsis
  • - The study examines how small RNA pathways in eukaryotes help protect gamete genomes from the harmful effects of transposable elements (TEs), while also noting that new TEs can occasionally invade and disrupt these processes, leading to sterility.
  • - Researchers focused on Drosophila (fruit flies) and discovered specific genetic variants that influence the severity of dysgenic sterility caused by P-element transposons, identifying two key quantitative trait loci (QTL).
  • - The findings suggest that fertile Drosophila genotypes not only express more splicing factors that prevent excessive transposase production but also show improved DNA repair mechanisms, enabling them to better cope with the damaging effects of rapid TE transposition. *

This study leveraged the phylogenetic analysis of more than 10K strains of novel coronavirus (SARS-CoV-2) from 67 countries. Due to the requirement of high-end computational power for phylogenetic analysis, we leverage a fast yet highly accurate alignment-free method to develop the phylogenetic tree out of all the strains of novel coronavirus. K-Means clustering and PCA-based dimension reduction technique were used to identify a representative strain from each location.

Background: Gestational diabetes mellitus (GDM) is quite prevalent in low- and middle-income countries, and has been proposed to increase the risk of depression. There is only a prior study assessing antenatal depression among the subjects with GDM in the Bangladesh, which leads this study to be investigated.

Objective: To determine the prevalence of depressive symptoms and potential associations among pregnant women diagnosed with GDM.
