RESUMEN

A significant proportion of patients undergoing repair of congenital mitral valve disease will require a subsequent reoperation. During somatic growth, mitral valve repair is preferable to replacement as it allows for annular growth, preservation of ventricular function, and avoidance of lifelong anticoagulation. Techniques to facilitate successful re-repairs for congenital and non-rheumatic mixed degenerative mitral valve disease are not well-described in the literature. Description of the encountered pathology and surgical maneuvers utilized in this case provides real-world tools to help surgeons deal with limited orifice availability, fibrosis, and multilevel lesions. We describe a mitral valve re-repair in a young athlete for a rare cleft posterior mitral leaflet, with a simultaneous tricuspid valve repair and Cox-Maze procedure. We focus on technical pearls that address specific anatomic challenges within our surgical approach.

RESUMEN

OBJECTIVE: Surveillance metrics in pediatric and young adult Marfan syndrome (pMFS) are challenging. We evaluated the utility of aortic root cross-sectional area/height index (CSA/Ht) on echocardiogram among pMFS patients as a risk stratification and surgical triage metric. METHODS: Genotype or phenotype positive pMFS patients aged 25 years or younger seen at our center from 2001 to 2020 were identified. Time-related transition to surgery was modeled using parametric methods. Predictive utility of CSA/Ht compared with aortic root diameter (ARd) and root Z score (ARz) were modeled using nonlinear multivariable parametric and nonparametric longitudinal regression models. RESULTS: Seventy-nine patients (43% female) presented at median age of 5.8 years (15th-85th percentile, 0.75-17 years) with median follow-up of 4.4 years (range, 0-18.5 years). Baseline echocardiography data were: CSA/Ht, 3.9 ± 1.4 cm2/m; ARd, 2.4 ± 0.89 cm; and ARz, 2.4 ± 1.7. CSA/Ht tracked ARd better compared with ARz (r = 0.91 vs 0.24). Eighteen patients underwent surgery. Surgical procedures included at least 2 components in 17 (aortic, mitral, tricuspid, aortic root, and arch procedures) and isolated mitral valve procedures in 1 patient. Time-related transition to surgery showed a prominent early phase to 1 year post presentation, followed by a slowly increasing late phase. CSA/Ht had a more linear correlation versus ARz during periods of rapid somatic growth in surgical patients. Surgical repair occurred at CSA/Ht between 5 and 7 cm2/m. CONCLUSIONS: CSA/Ht tracked ARd well over time. CSA/Ht between 5 and 7 cm2/m might be a promising metric for surgical triage in pMFS patients. CSA/Ht surgical threshold values in pMFS patients occurred at lower than current accepted "surgical" threshold values for CSA/Ht in adult Marfan syndrome patients.

RESUMEN

In Lebanon, cancer used to be regarded as a taboo and referred to as "the disease" and was rarely disclosed to patients. However, patients are now increasingly interested in knowing their cancer status but with varying degrees of information requested. The aim of this qualitative descriptive study was to explore the perceptions of cancer patients, their families, oncologists, and healthy individuals concerning the disclosure of cancer prognosis. In-depth interviews were conducted with 21 family members, 20 middle-aged cancer patients, 11 elderly cancer patients, 22 healthy individuals, and 6 oncologists at the American University of Beirut Medical Center. The interviews focused on the following: general perception of cancer in Lebanese society, type, and extent of information that should be disclosed, factors affecting patient autonomy, and elements contributing to the decisions taken by oncologists and patients. The oncologist's compassion and communication with patients affected their emotional status greatly, and some gaps in communication skills of oncologists were in need of standardized training courses to improve the process of cancer status disclosure. Also, patients had an increased preference towards the disclosure of cancer prognosis, and a desire to know the truth and this need increased as the patient progressed to a terminal state. Future work should be directed at addressing the needs of cancer patients through every disease stage. More research and further deliberation are needed to confirm the findings of this study since the Lebanese Code of Medical Practice does not protect the right of full disclosure.

RESUMEN

BACKGROUND: Colorectal cancer (CRC) remains a deadly disease, afflicting the lives of millions worldwide. The prognosis of CRC patients is best predicted by surgical resection and pathological analysis of specimens. Emerging evidence has attributed a significant role to inflammatory markers and microRNAs (miRNAs) in the prognosis and survival of CRC patients. AIM: Here, we review the literature on inflammatory markers and miRNAs with an established role on survival rates, response to systemic chemotherapy, and other clinic-pathological parameters in CRC patients. RESULTS: Our literature review revealed a critical role of inflammatory markers­specifically, the acute-phase proteins, inflammatory cytokines, and blood cell ratios­on prognostic outcomes in CRC patients. MiRNAs, on the other hand, were useful in predicting prognosis and clinical response and accordingly stratifying CRC patients for optimal drug selection. CONCLUSION: These biomarkers are easily measured in routine blood exams and can be used in adjunct to the tumor-node-metastasis (TNM) staging system to identify high-risk patients and those who are more likely to benefit from chemotherapy and other targeted therapies. However, more prospective studies are needed for the validation of these discussed prognostic and predictive biomarkers.
