Background: Long-term survival after emergency colorectal cancer surgery is low, and its estimation is most frequently neglected, with priority given to the immediate prognosis. This study aimed to propose an effective nomogram to predict overall survival in these patients. Materials and methods: We retrospectively studied 437 patients who underwent emergency surgery for colorectal cancer between 2008 and 2019, in whom we analyzed the clinical, paraclinical, and surgical parameters. Results: Only 30 patients (6.86%) survived until the end of the study. We identified the risk factors through the univariate Cox regression analysis and a multivariate Cox regression model. The model included the following eight independent prognostic factors: age > 63 years, Charlson score > 4, revised cardiac risk index (RCRI), LMR (lymphocytes/neutrophils ratio), tumor site, macroscopic tumoral invasion, surgery type, and lymph node dissection (p < 0.05 for all), with an AUC (area under the curve) of 0.831, with an ideal agreement between the predicted and observed probabilities. On this basis, we constructed a nomogram for prediction of overall survival. Conclusions: The nomogram created, on the basis of a multivariate logistic regression model, has a good individual prediction of overall survival for patients with emergency surgery for colon cancer and may support clinicians when informing patients about prognosis.

Background/Objectives: Hartmann’s procedure is commonly employed to manage complications of acute sigmoid diverticulitis, such as perforation or abscess formation. However, determining the optimal timing for colostomy reversal remains a topic of debate. This study aims to evaluate the effect of early versus delayed colostomy reversal on postoperative outcomes, focusing on complications, hospital stay duration, and readmission rates. Methods: A retrospective cohort study was conducted on 148 patients who underwent Hartmann’s procedure for acute sigmoid diverticulitis at a single tertiary care center between 2014 and 2023. Participants were grouped based on the timing of colostomy reversal: early (45–120 days), intermediate (121–180 days), and late (>180 days). Data on complications, hospital stay length, and readmissions were analyzed. Results: Early reversal was associated with fewer postoperative complications, shorter hospital stays, and reduced readmissions compared to delayed reversal. The late reversal group had higher rates of complications, longer hospital stays, and a higher need for reintervention. Advanced age and comorbidities, such as cardiovascular disease and diabetes, were significant predictors of poor outcomes, contributing to delayed reversal. Logistic regression analysis indicated that late reversal was independently associated with higher complication rates. Conclusions: Early colostomy reversal within 45–120 days following Hartmann’s procedure is associated with improved postoperative outcomes, including fewer complications and a shorter hospital stay. The timing of colostomy reversal should be individualized based on patient health status, with early reversal preferred for those without significant comorbidities. Further prospective research is needed to confirm these findings and refine guidelines for optimal reversal timing.

Background and Objectives: The treatment of advanced and metastatic lung cancer is multimodal, and it is coordinated by a multidisciplinary team. Anxiety and depression occur frequently in patients with lung cancer, creating considerable discomfort in therapeutic management. At the same time, these psychoemotional symptoms affect the patients’ quality of life. Objective: This research seeks to identify correlations both between anxiety and depression and the patients’ performance statuses, as well as between anxiety and depression and the type of treatment: radiotherapy, chemotherapy, tyrosine kinase inhibitors (TKI), immunotherapy and palliative care. Materials and Methods: The study evaluated 105 patients with lung cancer from two oncologic centers. Patients were assessed for anxiety and depression using the questionnaire Hospital Anxiety and Depression Scale (HADS). The HADS is a self-report rating scale of 14 items. It measures anxiety and depression, and has two subscales. There are seven items for each subscale. There are 4-point Likert scale ranging from 0 to 3. For each subscale, the score is the sum of the seven items, ranging from 0 to 21. Results: The most powerful correlation with statistical significance was observed between the IT type of treatment (immunotherapy) and the normal level of anxiety, PC = 0.82 (p < 0.001) as well as the normal level of depression. Palliative treatment was correlated with anxiety and depression, both borderline and abnormal. For ECOG 3–4 performance status and abnormal anxiety, respectively, abnormal depression was significantly associated. Also, continuous hospitalization was associated with abnormal anxiety and depression. Conclusions: Early assessments of anxiety and depression are necessary in patients with advanced and metastatic lung cancer, with unfavorable performance status, who have been admitted to continuous hospitalization, and who require palliative care.

Introduction: The aim of this study is to evaluate the results of online group meetings for breast cancer patients in the active phase of treatment. The group therapy sessions took place weekly, synchronously, online, on Zoom, with a total of 12 meetings lasting about 2.5 h per session, between December 2021 and February 2022. We analyzed the topics of discussion chosen by the participants, the structure of the group, the results obtained at the main scales of evaluation/monitoring of quality of life and the motivation of patients to participate in the therapeutic group. All patients were in the active phase of treatment (chemotherapy, radiotherapy, hormone therapy, etc.). The main goal of the group therapy was to reduce the stress related to the disease. Material and methods: Systematic observations included ABS psychological tests, EQ-5D-5L, HADS—Hospital Anxiety and Depression Scale, and the Recurrence Fear Questionnaire; the questionnaires were administered at the beginning and at the end of the therapeutic intervention; the participation in the therapy and in the research of the patients began after signing the informed consent document; the intervention was evaluated at the end using a feedback questionnaire. The group was closed, and the participants signed an informed consent document and agreed to have the sessions recorded. Results: Comparing the initial with the final results of the psychological tests administered, there was an improvement in the quality of life of the participants in all areas, with a clinically significant decrease in the areas of pain and depression, along with an increase in perception of well-being, a decrease in FoP scores and an increase in the level of rationality about the disease. Conclusions: Group therapy for cancer patients was useful in improving the quality of life; the closed group, even online, provided a safe environment in which they could share feelings. A close correlation was noted between the scores obtained on the FoP-Q and HADS scales. It is evident that there is a strong relationship between FoP and depression. Results on these scales correlated well with results on the EQ-5D-5L quality of life questionnaire.

Gynecologic melanomas are uncommon and malignant mucosal melanomas with vaginal origin are extremely rare, treatment strategies are limited and extrapolated from those of cutaneous melanoma. A better understanding of the vulvovaginal melanoma’s biology and its risk factors is needed. Therapeutic strategies include surgery, systemic therapy and radiotherapy. For vulvovaginal melanoma, surgery is selected as the primary treatment. Immunotherapy and target treatment have recently enhanced the systemic therapy for cutaneous melanoma (CM). Immunotherapy and new target agents demonstrated a better survival of melanoma and might be considered as treatment of vulvovaginal melanoma. Radiotherapy is included in the therapeutic arsenal for mucosal melanoma and may be performed on selected patients who may receive concurrent checkpoints and inhibition neoadjuvant radiotherapy with the purpose of reducing morbidity and mortality.

Background and Objectives: Biological correlates of baseline clinical responsiveness remain incompletely characterized in older adults with acute ischemic stroke treated with intravenous thrombolysis. We evaluated associations between admission Glasgow Coma Scale (GCS) and pre-thrombolysis hematologic, inflammatory, iron-status, and micronutrient parameters. Materials and Methods: This retrospective single-center cohort included 95 unique patients aged ≥65 years, all treated with intravenous alteplase between 2020 and 2024. Admission GCS ranged from 11 to 14. Spearman correlations used original GCS scores. Principal proportional odds models used ordered GCS categories of 11–12, 13, and 14, and were adjusted for age, sex, and admission National Institutes of Health Stroke Scale (NIHSS), with false discovery rate corrections. Sensitivity analyses additionally considered clinician-documented aphasia, congestive heart failure, atrial fibrillation, and reperfusion status for 24 h GCS change. Results: Admission GCS correlated most strongly with RDW-CV (rho = −0.843; 95% bootstrap CI, −0.892 to −0.774) and MCV (rho = 0.779; 95% CI, 0.668 to 0.866). Principal adjusted odds ratios per one-SD increase were 5.68 for hemoglobin, 3.01 for log-transformed ferritin, 4.71 for serum iron, 4.71 for log-transformed vitamin B12, 0.20 for C-reactive protein, and 0.019 for RDW-CV (all FDR-adjusted p < 0.001). Association directions remained consistent in sensitivity analyses. MCV showed an exploratory nonlinear association. No biomarker was associated with the direction of 24 h GCS change after FDR correction, including reperfusion-adjusted models. Conclusions: Pre-thrombolysis biological parameters were concurrently associated with baseline GCS within this single-center cohort and restricted GCS range. These associations do not establish causality, independence from unmeasured lesion location or infarct volume, predictive utility, or early neurological recovery. Prospective external validation is required.
