Evaluation of Breast Disease Using Triple Assessment Test with Ultrasonography as the Fourth Component

Breast disease is a significant health concern, with varying clinical presentations and diagnostic challenges. This study aims to assess the accuracy and utility of ultrasonography (USG) as an adjunct component to the Modified Triple Assessment Test (MTT) in the screening and diagnosis of breast diseases. A total of 40 patients with breast complaints, including lumps, nipple discharge, or retraction, were included. The MTT, consisting of clinical examination, mammography, fine-needle aspiration cytology (FNAC), and histopathological examination (HPE), was performed on all patients under informed consent. USG was added as a fourth component. Data on age distribution, parity, menstrual status, side of breast lump, location of tumors, and histopathological findings were collected and analyzed. In the 30-39 age group, breast lumps were common, with nulliparous women showing more malignant cases. Pre-menopausal women had benign lumps, while peri-menopausal and post-menopausal women had more malignancies. Left-sided lumps prevailed, and the upper outer quadrant was the common location. Clinical examination had high accuracy, as did ultrasonography (USG). This study underscores the importance of personalized breast health approaches, considering age, parity, and menstrual status. The combination of clinical examination, mammography, FNAC, and USG (MTT) provides a reliable diagnostic tool for breast disease, with MTT serving as a valuable modality for breast carcinoma diagnosis and treatment planning

Coagulation Markers as Predictive and Prognostic Factors in Carcinoma Breast Patients with Lymph Node Metastasis

  Objective: The purpose of this prospective observational study was to evaluate the predictive and prognostic value of coagulation markers in patients with lymph node metastases and cancer of the breast, as well as their associations with important histopathologic criteria. Methods: Between December 2020 and July 2022, 100 patients from the surgery department of a tertiary hospital were enrolled in the study. D-dimer, fibrinogen, and prothrombin time were assessed as coagulation indicators. Documented histopathologic characteristics included tumor grade, size, lymph node involvement, and estrogen receptor status. Chi-square tests, t-tests, Kaplan-Meier survival curves, and log-rank tests were all used in the statistical study. Results: Elevated D-dimer levels were significantly associated with higher tumor grade (p < 0.05) and lymph node involvement (p < 0.01). Elevated fibrinogen levels were linked to larger tumor size (p < 0.05). Abnormal coagulation markers were correlated with reduced disease-free survival (p < 0.001). Conclusion: In breast cancer patients with lymph node metastases, coagulation indicators have the potential to predict disease severity and prognoses. Together with established parameters, their clinical utility may result in more precise care and better patient outcome

Role of Neoadjuvant Paclitaxel Chemotherapy in Carcinoma Breast: A Prospective Study

  Objective: The purpose of this prospective study was to assess the value of neoadjuvant chemotherapy with paclitaxel in the treatment of breast cancer. Methods: There were 88 diagnosed breast cancer patients altogether, 44 in each of the two groups (paclitaxel group and control group). To verify eligibility, thorough clinical, radiological, and laboratory evaluations were made. The reduction of tumor size, pathological reactions, and safety profiles were evaluated. To compare results between groups, statistical tests were used during data processing. Results: At 12 and 24 weeks, the paclitaxel group showed significantly smaller tumor sizes than the control group. In the paclitaxel group, complete pathological responses were more common, indicating efficient tumor regression. The side effects of paclitaxel therapy were generally well-tolerated and controllable. Conclusion: In conclusion, patients with breast cancer showed encouraging improvements in histological responses and tumor size after neoadjuvant paclitaxel treatment. These results suggest the potential advantages of using paclitaxel in neoadjuvant therapy protocols, perhaps making breast-conserving surgery more feasible. In order to provide more individualized treatments, future research should investigate long-term outcomes and biomarkers indicative of paclitaxel sensitivit

Kinetic and Mechanistic Study of Glucose Isomerization Using Homogeneous Organic Brønsted Base Catalysts in Water

The isomerization of glucose to fructose represents a key intermediate step in the conversion of cellulosic biomass to fuels and renewable platform chemicals, namely, 5-hydroxymethyl furfural (HMF), 2,5-furandicarboxylic acid (FDCA), and levulinic acid (LA). Although both Lewis acids and Brønsted bases catalyze this reaction, the base-catalyzed pathway received significantly less attention due to its lower selectivity to fructose and the poor yields achieved (\u3c10%). However, we recently demonstrated that homogeneous organic Brønsted bases present a similar performance (∼31% yield) as Sn-containing beta zeolite, a reference catalyst for this reaction. Herein, we report on the first extensive kinetic and mechanistic study on the organic Brønsted base-catalyzed isomerization of glucose to fructose. Specifically, we combine kinetic experiments performed over a broad range of conditions (temperature: 80–120 °C; pH 9.5–11.5; reactant: glucose, fructose) with isotopic studies and in situ 1H NMR spectroscopy. Pathways leading to isomerization and degradation of the monosaccharides have been identified through careful experimentation and comparison with previously published data. Kinetic isotope effect experiments were carried out with labeled glucose to validate the rate-limiting step. The ex situ characterization of the reaction products was confirmed using in situ 1H NMR studies. It is shown that unimolecular (thermal) and bimolecular (alkaline) degradation of fructose can be minimized independently by carefully controlling the reaction conditions. Fructose was produced with 32% yield and 64% selectivity within 7 min

Comparison of Conventional Sutures Versus Cyanoacrylate Glue in Clean Operative Wound Closure

Objective: The purpose of this study was to compare the efficiency and results of cyanoacrylate glue and traditional sutures in the closure of clean surgical wounds. Methods: This randomized controlled experiment was conducted between December 2020 and June 2022, enrolling 100 patients who met strict inclusion criteria. To close wounds, patients were given a random choice between using cyanoacrylate glue or traditional sutures. Wound healing, infection rates, patient satisfaction surveys, and cosmetic evaluations were all included of the postoperative assessments. Results: There were no appreciable differences between the two closure techniques in the rates of infection or wound healing. Patients in the cyanoacrylate glue group expressed considerably greater levels of satisfaction with their postoperative discomfort and pain reduction. Cosmetic assessments showed better results in the cyanoacrylate glue group, with lower ratings for scarring, erythema, and uneven skin texture. Conclusion: For a clean surgical wound closure, both traditional sutures and cyanoacrylate glue work well. Cyanoacrylate glue has benefits in terms of improved cosmetic results and patient comfort. The selection of the closure technique should take into account the unique characteristics and desires of the patient, highlighting the significance of patient-centered care in surgical decision-making. It is necessary to do additional study with larger sample numbers and long-term follow-up to validate these findings and investigate their relevance in various clinical setting

BACTERIAL DISEASES OF LIVESTOCK ANIMALS AND THEIR IMPACT ON HUMAN HEALTH

Recently, whole world is facing the problem of infectious diseases related to animal diseases that pose significant threats to human health. In other words, humans may acquire zoonotic infections through various routes i.e. food, water etc. The transmission of certain bacterial diseases (through food and water) is one of the important cause of illness in both developing and developed countries. Most of the infectious pathogens that are normally reside in the intestinal tract of healthy animals and may transmit the disease through products (meat, milk or eggs) and faecal contamination of the environment. Normally, minute amount of intestinal contents are released and contaminate milk during milking; carcass at slaughter and egg during laying. Generally, risk associated with this type of contamination is somehow minimised where proper food hygiene is normally applied throughout the entire food chain from production, through processing to preparation at home. In this view, we provide some information about bacterial diseases of livestock animals and their effect or impact on human health.Â

High temperature optical absorption investigation into the electronic transitions in sol–gel derived C12A7 thin films

Optical absorption into 6 mm thick sol–gel derived films, annealed at 1300 °C of 12CaO·7Al2O3 calcium aluminate binary compound on MgO〈100〉 single crystal substrates was studied at temperatures ranging from room temperature to 300 °C. Experimental data were analysed in both Tauc and Urbach regions. The optical band gap decreased from 4.088 eV at 25 °C to 4.051 eV at 300 °C, while Urbach energy increased from 0.191 eV at 25 °C to 0.257 eV at 300 °C. The relationship between the optical band gap and the Urbach energy at different temperatures showed an almost linear relationship from which the theoretical values of 4.156 and 0.065 eV were evaluated for the band gap energy and Urbach energy of a 12CaO·7Al2O3 crystal with zero structural disorder at 0 K
