A novel catalytic approach for the synthesis of symmetric and asymmetric azines has been developed. The environmentally benign protocol was achieved via condensation of 1-[(2-thienyl)ethylidene]hydrazine (1) with different aromatic aldehydes 2a–h and acetyl heterocyclic compounds (4, 6, 8, 10, and 12) in the presence of cellulose sulfuric acid (CSA) as the green catalyst. These procedures offer an interesting method for the large-scale industrial manufacture of azines due to their high percentage yield, mild reaction conditions, broad substrate range, and utilization of an economical and environmentally acceptable catalyst. Additionally, the molecular docking of the products to the monoamine oxidase (MAO-A) target protein was achieved to highlight the possible binding interaction with the amino acid residues Arg51, Glu43, Gly22, Gly49, Gly443, Ala272, Ile335, and Tyr407 at the point of binding. The binding interaction energy was discovered to be (− 6.48 kcal/mol) for the protein MAO-A (PDB ID: 2Z5X). The most effective azine derivatives 7 and 13 revealed some major conserved interactions between the MAO-A protein’s binding site amino acid residues and the PDB co-crystal ligand 2Z5X. Moreover, azine derivatives 3a and 3f showed the lowest binding activity with the target MAO-A.

Sacrococcygeal pilonidal sinus disease (SPND) is an acquired chronic disease with no precise etiopathogenesis. The morbidity associated with the disease necessitates the implementation of new techniques, such as sinus laser therapy (SiLaT), to improve disease management. However, surgical techniques as of now are preferred as the mainstay mode of treatment. A retrospective study was conducted to evaluate and report the healing outcome of the application of SiLaT on patients with SPND at a tertiary center. All patients who underwent SiLaT for primary or recurrent pilonidal sinus from February 2012 to December 2019 were included in the study and followed up for at least six months. Forty-one participants (37 males (90.2%) and four females (9.8%)) were included. Of the participants, 58.5% presented with chief complaints of painful swelling with mucopurulent discharge. Most of the participants were students (43.9%). SiLaT was the primary intervention for 82.9% of the participants. The mean duration of hospital stays, resumption of regular activity, and complete wound healing by secondary intention were 30±21.5 hours, 18.4±14.3 days, and 6.5±6.6 weeks, respectively. Around 95.1% of wounds healed without complications. The overall recurrence rate was 24.4%, while the recurrence rate with SiLaT being the primary intervention was 11.8%. Only three (7.32%) patients experienced wound infections as postoperative complications. The visual analog scale (VAS) score decreased postoperatively in the first and second weeks to 3.9±3.2 and 1.9±1.9, respectively, and 78.1% of the total patients showed satisfaction post-surgical interventions. The current study showed that the SiLaT technique is a feasible technology with promising results to evolve. Further studies are encouraged.

Aims: With the recently validated tool for estimating chronic pain after colorectal cancer surgery, the aims of this study were to calculate the prevalence and to identify predictive risk factors for chronic pain after colorectal cancer treatment.Method: Clinical data from colorectal cancer patients treated between 2001 and 2014 were obtained from the Danish Colorectal Cancer Group database. In 2016, all survivors were invited to participate in a national cross‐sectional questionnaire study on long‐term functional outcomes, including the chronic pain questionnaire. The prevalence of chronic pain was analysed in groups based on demographic data and treatment‐related factors. Multivariate logistic regression analysis was performed to determine significant predictors of chronic pain, displayed as odds ratios (OR) and 95% confidence intervals.Results: The response rate was 63.8%, representing 11 600 patients (7127 colon and 4473 rectal cancer patients). The overall prevalence of pain was 41.5%, with 15.4% having major pain. Major pain was more prevalent in rectal cancer patients than colon cancer patients (16.7% vs. 14.5%, p < 0.001). Predictors for major pain were: young age <60 years [OR 1.7 (95% CI 1.51–1.91)]; female sex [OR 1.63 (95% CI 1.46–1.82)]; an open surgical approach [OR 1.18 (95% CI 1.05–1.33)]; chemotherapy [OR 1.32 (95% CI 1.18–1.49)]; radiotherapy [OR 1.39 (95% CI 1.17–1.65)]; permanent stoma [1.56 (95% CI 1.31–1.86)]; comorbidity [OR 1.69 (95% CI 1.5–1.9)]; anastomotic leakage [OR 1.31 (95% CI 1.05–1.64)].Conclusion: Chronic pain is prevalent after colorectal cancer surgery. All patients should be informed about the risks before cancer treatment, particularly those who are at an increased risk of developing major pain.

Background: A stoma poses numerous physical, social, and psychological challenges and interferes with some religious practices, thus potentially negatively affecting the quality of life. In the contemporary era of stoma care, the study sought to assess this impact in a population with distinctive sociocultural characteristics. Methods: A modified City of Hope Quality of Life ostomy questionnaire was used to survey patients with intestinal stomas. The scoring was dichotomous on a 0 to 10 scale, where 0–3 indicated severe impact, 4–6 moderate, and 7–10 minimum. Statistical analysis involved Student’s t-test, one-way ANOVA, Spearman’s correlation, and multivariate linear regression. Results: There were 108 patients, with 59 males and 49 females. The mean age was 40.8 years. The overall quality of life score was 6, for the social domain 7, the physical domain 6, the psychological domain 5, and the spiritual domain 6. The stoma’s impact on the quality of life was severe in 2%, moderate in 61%, and minimal in 37% of patients. Young patients, women, and those with benign diseases or without a job had low scores. Furthermore, 90% of patients had difficulty performing religious activities. For the regression analysis, life quality predictors were dietary, religious, pouch and stoma site issues, leak, odor, diarrhea or constipation, depression, anxiety, and future and disease concerns. Conclusions: Despite advances in stoma care, stoma patients had multiple impediments to their life quality. These were mainly psychological, but the physical and religious ones were also significant. A holistic approach to managing stoma patients is thus needed to help them have fulfilling lives.
