Transmission and Regeneration of Sikh Self: Culture in the Making

The Sikh cultural narrative was explored using social representations in the public sphere. To this end textual analysis of newspaper articles (N=200) published from January 2003 to April 2005 was done. These analyses addressed four major domains: religio-cultural, political identity, contemporary trends, and redressing self-perception. The emerging themes evinced negotiation for creating a distinct space within the multicultural society of India. The task of putting one’s self-identity together, of making it coherent and presenting it to others as ‘their culture’, was warranted for making the boundaries of their community distinct from other existing groups. Bonding with the group emerged as the main source of motivation at the individual and community levels to assert a community’s identity

Association of biomarkers for human papillomavirus with survival among adults with Barrett high-grade dysplasia and esophageal adenocarcinoma

Importance: The presence of high-risk human papillomavirus (HPV) has been associated with a favorable outcome in Barrett high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC). Nevertheless, the prognostic significance of other HPV-related biomarkers (ie, retinoblastoma protein [pRb], cyclin D1 [CD1], minichromosome maintenance protein [MCM2] and Ki-67) is unknown. Objective: To examine the association between HPV-related biomarkers and survival in adult patients with Barrett HGD and EAC. Design, Setting, and Participants: This retrospective case-control study examined the hypothesis that the HPV-related cell cycle markers (pRb, CD1, and Ki-67) and the viral surrogate marker (MCM2) may be associated with a favorable prognosis in Barrett HGD and EAC. Pretreatment biopsies were used for HPV DNA determination via polymerase chain reaction and immunohistochemistry for the HPV-related biomarkers. Recruitment of patients occurred in secondary and tertiary referral centers, with 151 patients assessed for eligibility. The study period was from December 1, 2002, to November 28, 2017, and the dates of analysis were from September 9, 2011, to November 28, 2017. Main Outcomes and Measures: Disease-free survival and overall survival. Results: Of 151 patients assessed for eligibility, 9 were excluded. Among the 142 patients with Barrett HGD or EAC (126 [88.7%] men; mean [SD] age, 66.0 [12.1] years; 142 [100%] white), 37 were HPV positive and 105 were HPV negative. No association with disease-free survival was noted for pRb, CD1, Ki-67, and MCM2. In regard to overall survival, only low expression of CD1 had a favorable prognosis (hazard ratio [HR], 0.53; 95% CI, 0.30-0.95; adjusted P = .03). All the biomarkers stratified by HPV status showed significant associations with survival. Patients with HPV-positive, low-expression pRb esophageal tumors were associated with a significantly improved disease-free survival compared with the HPV-negative, high-expression Rb tumors (HR, 0.33; 95% CI, 0.12-0.93; adjusted P = .04). Similarly, HPV-positive, low-expression CD1 was associated with a significantly favorable disease-free survival (HR, 0.26; 95% CI, 0.09-0.76; adjusted P = .01), as was HPV-positive, high-expression MCM2 (HR, 0.27; 95% CI, 0.09-0.78; adjusted P = .02). In regard to overall survival, HPV was significantly associated only with low CD1 (HR, 0.38; 95% CI, 0.15-0.94; adjusted P = .04). Conclusions and Relevance: This study's findings suggest that low expression of CD1 appears to be an independent prognostic marker in Barrett HGD and EAC. Human papillomavirus positivity in combination with pRb, CD1, MCM2, and Ki-67 was associated with a survival benefit in esophageal tumors. These findings suggest the possibility of personalization of therapy for Barrett HGD and EAC based on viral status

Exploring the Dynamics of Negotiating Everyday Sexism in India: A Daily Diary Study

This study was undertaken to investigate the negotiation of everyday sexism encountered by college going young adult women in India in an urban context. An open-ended daily diary form was constructed, and 185 such forms were filled by 58 women enrolled in various colleges of a central university located in Delhi, India. These were analysed by content analysis with the help of NVivo software with a focus on target and type of sexism reported as well as response to sexist incident faced. The findings of this study reveal that participants chose inaction (53%) more than confronting sexism (47%), and reasons were identified for both confronting and not confronting sexism. Of those who did engage in confronting sexism, most chose collective confrontation i.e. confronting prejudice on behalf of one’s group. Confronting sexism appeared to be more difficult in the family context than with strangers, while there were no confrontations by bystanders, or men allies

Assessing the reliability of tele-refraction for real time consultation with a remote optometrist.

IntroductionUncorrected refractive errors pose a significant challenge globally, particularly in remote regions of low-middle income countries where access to optometric care is often limited. Telerefraction, which involves refraction by a trained technician followed by real-time consultation with remote optometrist, is a promising approach for such remote settings. This study aimed to evaluate the accuracy of this model.MethodsThis prospective study, conducted in New Delhi, compared tele-refraction to in-person examinations. Trained technicians used a simple device, Click-check, to perform objective refraction and a tele-refraction platform to enter the findings of objective refraction. Final prescription was made after consulting a remote optometrist on that platform. Masked face-to-face optometrists served as the gold standard. The study involved refraction in 222 patients and 428 eyes.ResultsTele-refraction demonstrated a strong agreement with in-person optometry, achieving 84.6% in spherical correction and 81% conformity in spherical equivalent. The mean difference of spherical equivalent between the two arms was only 0.11 D. The consultation with a remote optometrist improved conformity of spherical equivalent by 14.8% over objective refraction. 82 percent eyes matched in best corrected visual acuity and 92 percent were within 0.1 logMAR difference. For cylindrical axis, 74% eye were within acceptable 10 degrees of difference. The mismatch amongst the individual trained technicians, in terms of difference between the tele-refraction arm and the face-to face optometrist arm was found to be significant for cylindrical axis and not for spherical power and spherical equivalent.ConclusionOur study found tele-refraction by a trained technician comparable to refraction done by face-to-face optometrist. Tele-refraction, coupled with remote optometrist guidance can address the optometry resource gap in underserved areas. Thus, this model offers a transformative approach to enhancing the accessibility and quality of eye care services, which can significantly contribute to our efforts in achieving the global targets set by the World Health Organization for effective refractive error coverage. More standardized training for these technicians on ClickCheckTM for detecting the cylindrical axis with better accuracy, can improve this model further
