Effect of Flaxseed on Pain Relief and Quality of Life in Patients With Mastalgia: A Single Arm Interventional Study.

Objective: Mastalgia, a common complaint among women, denotes breast discomfort that can manifest as cyclical or non-cyclical. Reassurance, mechanical support and various non-pharmacological treatments, like flaxseeds, have been seen to have a good effect in treating mastalgia. Thus, the aim of this study was to investigates the efficacy of flaxseed in alleviating pain associated with mastalgia and its impact on the overall health-related quality of life among female patients. Materials and Methods: Conducted at a tertiary care center in Northern India over 18 months, it employed a single-arm interventional design. The participants included females aged 18 years and older presenting with breast pain at the Department of General Surgery. The intervention involved daily consumption of 30 g of milled flaxseed for each participant, administered over a period of six months. Pain severity was assessed using the visual analogue scale (VAS) before supplementation and at follow-up intervals up to six months. Concurrently, the Short Form-12 (SF-12) items Health Survey measured health-related quality of life, encompassing both physical and mental health domains. Statistical analysis employed parametric (paired t-test) and non-parametric tests (chi-square, McNemar) where appropriate, with statistical significance set at p<0.05. Results: Two hundred women with mastalgia were included with a significant reduction in mean VAS scores from 6.03±0.83 at baseline to 2.19±0.66 at six months post-intervention (p = 0.0001). This reduction in pain intensity demonstrated a positive correlation with duration of flaxseed supplementation, notably declining after the initial three months. The mean difference in physical and mental SF-12 score at first visit and at 6 months after intervention was significant (p = 0.0001). Conclusion: This study underscores the potential of flaxseed as a therapeutic option for managing mastalgia and enhancing health-related quality of life among affected individuals.

Assessing Residents in the Department of Surgery at a Tertiary Care Centre Using Mini-Clinical Evaluation Exercise (Mini-CEX).

OBJECTIVE: This study aimed to introduce, sensitize, and train our postgraduate students and faculty of the department of general surgery with the use of mini-Clinical Evaluation Exercise (mini­CEX) and to assess the perception of students and faculty towards it. MATERIAL AND METHODS: A cross­sectional observational study was conducted over a period of four months. Ten surgery residents in the department were asked to volunteer to participate and five professors conducted the session. Five sessions of mini­CEX (nine points) were conducted for each resident in different settings of the out­patient department (OPD) and in­patient department (IPD). A total of five skills were tested. Feedback from faculty and residents regarding the perception of mini­CEX was also taken. RESULTS: A statistically significant difference in mean scores of all domains was observed comparing the first and last assessment (p<0.05). Hundred percent of the residents scored superior category (7-9) in the final assessment in all domains, whereas the maximum was in a satisfactory scoring grade in 1st assessment. The time taken for the assessment significantly reduced from 1st assessment to the last assessment in OPD and IPD settings (p=0.001). The mini-CEX assessment tool got 100% feedback from faculty in terms of skill improvement, method, attitude of residents, and ability to identify gaps in knowledge. However, one assessor thought that "time given for assessment" was inadequate and more effort was required than the usual traditional assessment methods. The most identified problem faced by residents was that the "time given during assessment" was less (50%); however, overall residents also found it valid, effective, and helpful in identifying knowledge gaps and improving clinical and communication skills. CONCLUSION: Mini­CEX improves the learning environment in residency and also leads to improvement in medical interviewing skills, physical examination skills, humanistic qualities/professionalism, and counseling skills. So, it can be used for residency training in clinical departments.

Role of Reassurance and Proper Mechanical Support Advice on Quality of Life and Pain Relief in Patients of the Mastalgia-A Prospective Follow-up Study at A Tertiary Care Center in a Developing Country.

Objective: To study the effect of reassurance and proper mechanical support on quality of life (QOL) and visual analogue score (VAS) pain assessment in patients with mastalgia at a range of follow-ups. Materials and Methods: A prospective follow-up study was conducted among women aged 15-45 years, complaining of breast pain without any abnormality detected clinically and radiologically. After consent to participate and enrollment, all the study participants were counseled and reassured about the non-neoplastic nature of the disease and about wearing proper mechanical support/Bra; this was repeated at each follow-up. VAS was used to assess the pain intensity perceived by the woman at each follow-up, post intervention. The Short Form-36 (SF-36) scale was used to evaluate health related QOL (HRQOL). Results: Among 80 patients, 31.2% were wearing a Bra of fabric other than cotton, 21.2% were wearing a loose fit mechanical support/Brassiere, while 10% were not wearing any mechanical support at baseline. The overall mean VAS score was significantly reduced with each follow-up, indicating decreased perception of breast pain over time. There was a significant difference between the mean SF-36 score between base line and after three months (p<0.0001). Mean scores in all domains of the SF-36 increased. The greatest reduction in mean VAS score was seen in 26-35 years age group and women with a body mass index <18.5 kg/m2. Conclusion: Reassurance and wearing proper mechanical support/Bra are effective for improving QOL and alleviating breast pain/mastalgia. These simple processes should be used for the management of mastalgia.

Role of integrins in wound repair and its periodontal implications.

Wound healing in human periodontium is a complex process which involves both cell-cell and cell-matrix interactions. Integrins play a major role in regulation of these cell-cell, cell-matrix interaction. Wound healing involves two major events i.e. re-epithelialization and connective tissue repair. In this concise review, we will discuss the role of integrins in these major events as well as their impIications in periodontal wound repair. Integrins are differentially expressed in both of these major events. In re-epithelialization, keratinocytes express novel integrins receptors αvß1, α5ß1and αvß6 which are not expressed in normal healthy epithelium. Re-epithelialization also involves interaction of integrins with TGF-ß and fibronectin. Similarly, in connective tissue repair, the activation of fibroblast as well as the expression of integrins α5ß1 and α3ß1 is upregulated. In healthy periodontium, integrin αvß6 is normally expressed in junctional epithelium which is generally expressed only at wound sites in other parts of the body. The epithelialization at implant surface has not been yet fully explored with respect to interactions among integrins and other extra-cellular matrix molecules.

Role of osteopontin in bone remodeling and orthodontic tooth movement: a review.

In this review, most of the known and postulated mechanisms of osteopontin (OPN) and its role in bone remodeling and orthodontic tooth movement are discussed based on available literature. OPN, a multifunctional protein, is considered crucial for bone remodeling, biomineralization, and periodontal remodeling during mechanical tension and stress (orthodontic tooth movement). It contributes to bone remodeling by promoting osteoclastogenesis and osteoclast activity through CD44- and αvß3-mediated cell signaling. Further, it has a definitive role in bone remodeling by the formation of podosomes, osteoclast survival, and osteoclast motility. OPN has been shown to have a regulatory effect on hydroxyapatite crystal (HAP) growth and potently inhibits the mineralization of osteoblast cultures in a phosphate-dependent manner. Bone remodeling is vital for orthodontic tooth movement. Significant compressive and tensional forces on the periodontium induce the signaling pathways mediated by various osteogenic genes including OPN, bone sialoprotein, Osterix, and osteocalcin. The signaling pathways involved in the regulation of OPN and its effect on the periodontal tissues during orthodontic tooth movement are further discussed in this review. A limited number of studies have suggested the use of OPN as a biomarker to assess orthodontic treatment. Furthermore, the association of single nucleotide polymorphisms (SNPs) in OPN coding gene Spp1 with orthodontically induced root resorption remains largely unexplored. Accordingly, future research directions for OPN are outlined in this review.

Automatic segmentation of trophectoderm in microscopic images of human blastocysts.

Accurate assessment of embryos viability is an extremely important task in the optimization of in vitro fertilization treatment outcome. One of the common ways of assessing the quality of a human embryo is grading it on its fifth day of development based on morphological quality of its three main components (Trophectoderm, Inner Cell Mass, and the level of expansion or the thickness of its Zona Pellucida). In this study, we propose a fully automatic method for segmentation and measurement of TE region of blastocysts (day-5 human embryos). Here, we eliminate the inhomogeneities of the blastocysts surface using the Retinex theory and further apply a level-set algorithm to segment the TE regions. We have tested our method on a dataset of 85 images and have been able to achieve a segmentation accuracy of 84.6% for grade A, 89.0% for grade B, and 91.7% for grade C embryos.
