RESUMO

BACKGROUND: This study was conducted to explore the prevailing perceptions and experiences of caregiving burden among informal caregivers of women living with breast cancer in South India. METHODS: In-depth interviews were conducted among breast cancer care-receivers (n=35) and their informal caregivers (n=39) and a thematic analysis was used to analyze the data. Informal caregiver in the context of this study was defined as one who takes up the responsibility of an informal caregiving role, and were either self-identified or acknowledged by the care-receivers. RESULTS: Four main inductive themes in the domains of: emotional culpability, financial and workplace liability, psychosocial affliction, physical strain and health system demand were identified, that were associated with caregiver burden. CONCLUSION: Informal caregivers form an integral part of the cancer care continuum in India. It is recommended to factor in the identified themes while developing a caregiver needs assessment model in the context of caring for breast cancer patients in the Indian setting.

RESUMO

BACKGROUND: The increasing incidence of breast cancer necessitates the need to explore alternate screening strategies that circumvent the setbacks of conventional techniques especially among population that report earlier age at diagnosis. Serum autoantibodies is one such potential area of interest. However, their ubiquitous presence across cancer types limits its applicability to any one specific type of cancer. This review was therefore carried out to explore and consolidate available evidence on autoantibodies for early detection of breast cancer and to identify those that demonstrated a higher sensitivity. METHODS: A diagnostic test accuracy (DTA) review was carried out to ascertain serum autoantibodies that could be used for early detection of breast cancer among women. All relevant articles that investigated the role of autoantibodies in early detection of breast cancer were included for the review. MEDLINE, Scopus, ProQuest, Ovid SP, and Cochrane Library were searched extensively for eligible studies. Quality of the included studies was assessed using Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 tool. RevMan 5.3 was used for exploratory and MetaDTA 2019 for hierarchical analyses. The review helped identify the most frequently investigated autoantibodies and a meta-analysis further consolidated the findings. RESULTS: A total of 53 articles were included for the final analysis that reported over a 100 autoantibodies that were studied for early detection of breast cancer in women. P53, MUC1, HER2, HSP60, P16, Cyclin B1, and c-Myc were the most frequently investigated autoantibodies. Of these P53, MUC1, HER2, and HSP60 exhibited higher summary sensitivity measures. While the individual pooled sensitivity estimates ranged between 10 and 56%, the panel sensitivity values reported across studies were higher with an estimated range of 60-87%. CONCLUSION: Findings from the review indicate a higher sensitivity for an autoantibody panel in comparison to individual assays. A panel comprising of P53, MUC1, HER2, and HSP60 autoantibodies has the potential to be investigated as an early detection biomarker for breast cancer.

RESUMO

Multiplexed technologies for sexually transmitted infections offer a convenient diagnostics option to screen, confirm, and treat multiple pathogens simultaneously. Due to scarce published real-world diagnostic performance data, we did a systematic review. Two reviewers searched major databases for data published between Jan 1, 2009, and April 20, 2020, and abstracted and analysed sensitivity and specificity data from 24 studies, which assessed 17 multiplex rapid nucleic acid amplification test platforms and seven multiplex immunochromatographic devices. Overall, these studies evaluated 19 sexually transmitted infections in 26 126 individuals. High sensitivity and specificity were shown for rapid nucleic acid amplification platform tests and immunochromatographic devices, with performance varying by pathogen, device, seropositivity, and subpopulation screened. As most devices yielded more than 95% sensitivity and specificity, immunochromatographic tests and rapid nucleic acid amplification test platforms can be advised for screening and confirmatory use. These highly accurate devices are appropriate for integrated, rapid screening initiatives for sexually transmitted infections to screen and treat many of these infections simultaneously, for antimicrobial stewardship, and for disease elimination programmes.

RESUMO

BACKGROUND: Incidence of breast cancer and associated mortality are on the rise globally. Breast cancer incidence in India is on the rise and also accounts for a staggering 50% mortality rate among women. Health illiteracy, socio-economic and cultural barriers in addition to lack of an organized nationwide screening and prevention programme contribute to poor patient outcomes. Thus, it is imperative to strengthen the existing screening and treatment facilities to address the increasing cancer burden. In this regard, we conducted a workshop to investigate the scope of a multi- stakeholder engagement in breast cancer screening and treatment. METHODS: A stakeholder workshop grounded in an established co-design methodology  was convened in a semi-urban coastal district in South India with active participation of physicians, surgeons, occupational therapists, community leaders, programme officers, public health professionals and breast cancer survivors. Shiffman and Smith's framework was adapted to highlight barriers to screening and role of stakeholders in the co-design of solutions. RESULTS: Deliberate and active discussions marked the workshop proceedings resulting in the identification of   individual and systems level barriers, facilitators and implementation strategies. Social stigma and non-existent standard protocols for screening and referral were recognised as critical barriers, while community engagement and a dedicated patient advocate were the proposed facilitators. CONCLUSION: This workshop was an important step in bringing together key stakeholders and marked the beginning of the ICANTREAT initiative and a Community of Expertise. The outcomes highlight the importance of stakeholder involvement in the cancer- care pathway for breast cancer screening, diagnosis and treatment.

RESUMO

BACKGROUND: Breast cancer is reported to be the most common cancer among women in India with a high mortality to incidence ratio. Late presentation, driven by lack of awareness and limited accessibility to health services are some of the stated reasons for this. Given this context, this qualitative study was carried out to understand the perception of rural women towards the disease and factors that influenced utilization of available screening services among them. METHODS: Forty-four rural women aged 20-60 years from a coastal province in southern India participated in four Focus Group Discussions (FGDs) that were conducted to understand their perception, attitudes and barriers towards breast cancer screening. Participants were identified from the community through purposive sampling and constituted of home makers and working women. The FGDs were led by trained facilitators and the discussions recorded. Ideas and concepts that emerged were listed as codes. Related and similar codes were grouped to form six themes. RESULTS: Women in the study belonged to low- and middle-income households with a mean age of 42.8 ± 7.8 years and almost all had attended school. Although the respondents exhibited fairly good knowledge about the disease, cultural inhibitions, forgetfulness, economic constraints and apprehension towards tertiary health care facility were some of the barriers reported in the uptake of screening services. Participants hailed the role of female health care providers as motivational figures and stressed the need for easily comprehensible information dissemination strategies besides expecting an equal participation of men in issues involving women's health. CONCLUSION: Involving cancer survivors as educators and empowering men on women's health in addition to the felt need of a patient advocate to improve accessibility were some of the highlights of the discussions. Addressing these could go a long way in improving the cancer care continuum in the region.

RESUMO

BACKGROUND: Delivery of preventive care and chronic disease management are key components of a high functioning primary care practice. Health Centers (HCs) funded by the Health Resources and Services Administration (HRSA) have been delivering affordable and accessible primary health care to patients in underserved communities for over fifty years. This study examines the association between health center organization's health information technology (IT) optimization and clinical quality performance. METHODS AND FINDINGS: Using 2016 Uniform Data System (UDS) data, we performed bivariate and multivariate analyses to study the association of Meaningful Use (MU) attestation as a proxy for health IT optimization, patient centered medical home (PCMH) recognition status, and practice size on performance of twelve electronically specified clinical quality measures (eCQMs). Bivariate analysis demonstrated performance of eleven out of the twelve preventive and chronic care eCQMs was higher among HCs attesting to MU Stage 2 or above. Multivariate analysis demonstrated that Stage 2 MU or above, PCMH status, and larger practice size were positively associated with performance on cancer screening, smoking cessation counseling and pediatric weight assessment and counseling eCQMs. CONCLUSIONS: Organizational advancement in MU stages has led to improved quality of care that augments HCs patient care capacity for disease prevention, health promotion, and chronic care management. However, rapid technological advancement in health care acts as a potential source of disparity, as considerable resources needed to optimize the electronic health record (EHR) and to undertake PCMH transformation are found more commonly among larger HCs practices. Smaller practices may lack the financial, human and educational assets to implement and to maintain EHR technology. Accordingly, targeted approaches to support small HCs practices in leveraging economies of scale for health IT optimization, clinical decision support, and clinical workflow enhancements are critical for practices to thrive in the dynamic value-based payment environment.

RESUMO

In 2019, the U.S. Department of Health and Human Services launched the Ending the HIV Epidemic: A Plan for America (EHE) initiative to end the U.S. human immunodeficiency virus (HIV) epidemic by 2030. A critical component of the EHE initiative involves early diagnosis of HIV infection, along with prevention of new transmissions, treatment of infections, and response to HIV outbreaks (1). HIV testing is the first step in identifying persons with HIV infection who need to be engaged in treatment and care as well as persons with a negative HIV test result and who are at high risk for infection and can benefit from HIV preexposure prophylaxis (PrEP) and other prevention services. These opportunities are often missed for persons receiving clinical services in ambulatory care settings (2). Data from the 2009-2016 National Ambulatory Medical Care Survey (NAMCS) and 2009-2017 National Hospital Ambulatory Medical Care Survey (NHAMCS) were analyzed to estimate trends in HIV testing at visits by males and nonpregnant females to physician offices, community health centers (CHCs), and emergency departments (EDs) in the United States. HIV tests were performed at 0.63% of 516 million visits to physician offices, 2.65% of 37 million visits to CHCs, and 0.55% of 87 million visits to EDs. The percentage of visits with an HIV test did not increase at visits to physician offices during 2009-2016, increased at visits to CHC physicians during 2009-2014, and increased slightly at visits to EDs during 2009-2017. All adolescents and adults should have at least one HIV test in their lifetime (3). Strategies that reduce clinical barriers to HIV testing (e.g., clinical decision supports that use information in electronic health records [EHRs] to order an HIV test for persons who require one or standing orders for routine opt-out testing) are needed to increase HIV testing at ambulatory care visits.

RESUMO

OBJECTIVE: Cancer care is physically and psychologically challenging for both care recipients and caregivers. Caregiving in cancer is an area that needs urgent attention in India. Much of caregiving literature in India is limited to mental illnesses. This study thus examines the perceptions and practices of psychological caregiving among caregivers and care recipients of breast cancer in India. METHODS: Participants were interviewed with the aid of a semistructured qualitative interview guide. Participants included 39 caregivers and 35 care recipients in different breast cancer stages. Interviews were transcribed, translated to English, and coded, and themes were derived for further analysis. Informed consent from participants and ethical clearance and permission from a tertiary hospital were obtained prior to data collection. RESULTS: Psychological caregiving as perceived by the participants included actions such as encouraging, convincing care recipients, companionship, and maintaining a stress-free environment. Caregivers in particular felt that psychological caregiving meant reacting calmly to sensitive queries of nonfamily members, providing emotional support to other family members, and involvement in religious activities. Taking on such diverse responsibilities gave rise to several unmet psychological needs such as motivation and support in decision making from other family members. CONCLUSIONS: Irrespective of the status (caregiver or care recipient), participants in this study felt the need for structured counselling services to be incorporated into the standard care protocol. This is an area that needs to be further explored in the context of the breast cancer caregiver and care recipient dyad.

RESUMO

Objective: Globally oral cancer is one of the ten most common cancers with prevalence being high in Central and South East Asian countries. This survey was conducted to estimate the prevalence of oral pre-malignant lesions (OPML) and to identify their risk factors. Methods: A community based cross-sectional study was carried out among 2033 individuals aged ≥18 years. A questionnaire was administered to collect socio-demographic characteristics, various risk factors for oral cancer and presence of its symptoms. Oral cavity of all the participants was examined in detail by the study investigator as per WHO guidelines for the early diagnosis of oral neoplasia. Result: The prevalence of OPML was found to be 3.73%. Among those with OPML, all were ever tobacco consumers and had poor oral hygiene. A significant association was observed between OPML and younger age group (OR=2.56, 95% CI 1.08-6.02), males (OR=26.76, 95% CI 8.40-85.19) and low socio-economic status (OR = 1.91, 95% CI 1.20-3.02). Tobacco (p<0.001), alcohol (OR= 7.92, 95% CI 4.77-13.14) and areca nut consumption (OR = 5.48, 95% CI 3.42-8.77) were strongly associated with OPML. On multivariate analysis among ever tobacco users, OPML was associated with younger individuals, males and those using smokeless forms of tobacco (p <0.05). The study showed that the participants with OPML were more likely to be never married (OR=1.6, 95% CI 0.92-2.96),to be unskilled workers (OR= 1.45, 95% CI 0.61-3.43), to have suffered from oral trauma (OR =1.30, 95% CI 0.75-2.26), to have consumed hot and spicy food frequently (OR=1.53, 95% CI 0.96-2.24), to have consumed fruits infrequently (OR=1.53, 95% CI 0.90-2.59) and to report family history of any cancer (OR = 1.29, 95% CI 0.58-2.87) . However, these associations were statistically insignificant. Conclusion: The study reinforces that use of substances such as tobacco, alcohol and areca nut are the modifiable risk factors for OPML.

RESUMO

HRSA supported health centers have a long history of participating in ambulatory care accreditation; however, there is a dearth of information on the relationship between accreditation and quality of care. We conducted a cross-sectional study of 1,202 health centers, using multivariate regression to estimate the association between accreditation and 14 clinical quality measures, controlling for patient and organizational characteristics. We also predicted national estimates of accreditation-related improvement in quality. Adjusted analyses show that accredited health centers achieved higher performance on adult weight screening and follow-up (coef = 0.037, p < .05), tobacco cessation intervention (coef = 0.042, p < .05), and use of lipid-lowering therapy (coef = 0.028, p < .05). Study results show that universal accreditation could result in additional 552,087 adult patients receiving weight screening and follow-up, 157,434 receiving tobacco cessation intervention and 25,289 receiving lipid-lowering therapy. This is the first national study to examine the impact of accreditation on health center quality of care. Findings suggest that HRSA support for accreditation has the potential to improve quality of care and as a result, reduce health disparities in underserved communities across the United States. Further research is necessary to identify specific elements of accreditation that have the greatest impact on quality of care.

RESUMO

BACKGROUND: Pioglitazone has better cardiovascular outcomes and a questionable relationship with bladder carcinoma in diabetes mellitus, type II (DM-2). We sought to evaluate the role of pioglitazone in the Indian population. METHODS: This is a retrospective study at an academic medical center in India. All DM-2 patients in 2008 with a new prescription of pioglitazone were age- and gender-matched with non-users. We excluded patients with gestational DM or DM type I. They were followed forward for five years and demographic data, micro- and macro-vascular complications, mortality, and bladder carcinoma were recorded. Two-tailed p ≤ 0.05 was considered statistically significant. RESULTS: Two cohorts of 260 patients, with mean age of 58 ± 11 years with 413 (79.4%) males, were followed for five years. Pioglitazone users had higher hypertension, obesity, DM-2 family history (all p < 0.003), and use of insulin and oral hypoglycemics (all p < 0.0001) in comparison to non-users. HbA1c was not different between groups. Over five years, pioglitazone users had lesser retinopathy and myocardial infarctions (all p < 0.01). Five cases of bladder carcinoma were noted, all in the pioglitazone group, however without statistical significance. Baseline variables, including mean daily pioglitazone dose, were not statistically different between patients with and without bladder carcinoma. Nephropathy and MI were independent predictors for development of bladder carcinoma within pioglitazone users. CONCLUSIONS: Pioglitazone users had significantly lesser myocardial infarctions and retinopathy despite more difficult to control DM 2. In an age- and gender-matched cohort of users and non-users, pioglitazone did not contribute to development of bladder cancer in the Indian population.

RESUMO

BACKGROUND: Physical activity trends for a lower-middle income country like India suggest a gradual decline in work related physical activity and no concomitant increase in leisure time physical activity. Perceived health benefits of physical activity and intention to increase physical activity have been established as independent correlates of physical activity status. In India, not much is known about peoples' perceptions of health benefits of physical activity and their intention to increase physical activity levels. This study was performed to understand peoples' perceptions and awareness about health benefits of physical activity in a rural South Indian region. METHODS: This cross-sectional study was conducted using a multistage cluster sampling design. A content validated, field tested questionnaire was administered in person by a trained interviewer in the participants' native language. The questionnaire assessed the participants' perceptions about their lifestyle (active or sedentary), health benefits of physical activity and need for increasing their physical activity. In addition, the participant's physical activity was assessed using version 2 of global physical activity questionnaire. Frequencies and percentages were used to summarise perceived health benefits of physical activity and other categorical variables. Age and body mass index were summarised using mean ± SD, whereas physical activity (MET.min.wk -1) was summarised using median and interquartile range. RESULTS: Four hundred fifty members from 125 randomly selected households were included in the study, of which 409 members participated. 89% (364) of participants felt they lead an active lifestyle and 83.1% (340) of participants did not feel a need to increase their physical activity level. 86.1%, (352) of the participants were physically active. Though 92.4% (378) of participants felt there were health benefits of physical activity, majority of them (75.1%) did not report any benefit related to chronic diseases. None mentioned health benefits related to heart disease or stroke. CONCLUSION: There is low awareness of chronic disease related benefits of physical activity and participants do not see a need to increase their physical activity level. Public health awareness programs on importance and health benefits of physical activity would be useful to counter the anticipated decline in physical activity.

RESUMO

BACKGROUND: Breast cancer being one of the leading cancers among women in developing countries, prevention or identification of the disease at an early stage is of paramount importance in saving as well as improving the quality of life. Breast health awareness appears to be a pragmatic method for this. OBJECTIVE: To determine the acceptability and effectiveness of an educational intervention programme on breast health awareness for rural women by trained female health workers. SETTINGS AND DESIGN: Community based non-randomised educational intervention study carried out over a period of 1 year. Three hundred and sixty rural women in the age group 30--59 years were randomly selected (and age-wise stratified), from a coastal village in Southern India. METHODS: Women were educated on breast health and breast self-examination by specifically trained health workers and their awareness and proficiency levels were evaluated at the end of 1 and 3 months post-intervention. STATISTICAL ANALYSIS: This was done using the Statistical Package for Social Sciences Version 10. RESULTS: Following the educational intervention, a significant increase in overall awareness regarding breast cancer (z=-15.807; P< 0.001) as well as in the performance of self-examination of the breast 321/342 (93%) was observed. Forgetfulness or being too busy appeared to be the two most frequently perceived barriers. CONCLUSION: This study clearly shows that a community oriented educational intervention programme emphasizing on proper technique can bring about the desirable behavioural change among women.

RESUMO

The daily intake of natural Th and its contents in lungs, skeleton and liver of an Indian adult population group were estimated using radiochemical neutron activation analysis (RNAA) technique. These data on daily intake (through inhalation and ingestion) were used to compute Th contents in lungs and other systemic organs such as skeleton and liver using the new human respiratory tract model (HRTM) and the new biokinetic model of Th. The theoretically computed Th contents in lungs, skeleton and liver of an average Indian adult are 2.56, 4.00 and 0.17 microg, respectively which are comparable with the corresponding experimentally measured values of 4.31, 3.45 and 0.14 microg in an urban population group living in Mumbai. The measured lung contents of Th in a group of five occupational workers were used to compute their total body Th contents and the corresponding daily urinary excretions. The computed total body contents and daily urinary excretions of Th in the five subjects compared favourably with their measured values. These studies, thus, validate the new biokinetic model of Th in natural as well as in occupational exposures in Indian conditions.
