RESUMO

Breast cancer, a global health concern predominantly affecting women, recorded 2.3 million new cases and 685,000 deaths in 2020. Alarmingly, projections suggest that by 2040, there could be over 3 million new cases and 1 million deaths. To assess breast cancer prevalence in 24 rural villages within a 60 km radius of NIMS Hospital, Tala Mod, Jaipur, Rajasthan, North India 303,121. A study involving 2023 participants conducted initial screenings, and positive cases underwent further tests, including ultrasound, mammography, and biopsy. SPSSv28 analysed collected data. Among 2023 subjects, 3 screened positive for breast lumps. Subsequent clinical examination and biopsy identified 1 normal case and 2 with breast cancer, resulting in a prevalence proportion of 0.0009 or 98 per 100,000. This study helps fill gap in breast cancer prevalence data for rural Rajasthan. The results highlight a concerning prevalence of breast cancer in the rural area near NIMS hospital, emphasizing the urgent need for increased awareness, early detection, and better healthcare access. Challenges like limited resources, awareness programs, and delayed diagnosis contribute to this high incidence. To address this, comprehensive approach is necessary, including improved screening programs and healthcare facilities in rural areas. Prioritizing rural healthcare and evidence-based strategies can reduce the burden of breast cancer and improve health outcomes.

RESUMO

BACKGROUND: There is a need to improve speaker diversity at gastroenterology conferences, but little public data exist to quantify this. In addition, the perception of diverse speakers by conference audiences is not appreciated. We sought to identify time trends in speaker profiles and audience ratings at a national inflammatory bowel diseases conference. METHODS: Faculty profiles and audience feedback forms from 2014 to 2020 were reviewed for an annual inflammatory bowel diseases meeting. Speaker demographics including gender, race, and years of experience post-training were collected. Continuing medical education surveys were examined for audience ratings of speakers' knowledge level and teaching ability. RESULTS: Six years of data were collected, including 560 main program faculty and 13 905 total feedback forms. The percentage of female speakers increased from 25% in 2016 to 39% in 2020. All-male panels decreased from 47% in 2014 to 2017 to 11% in 2018 to 2020. Racial diversity of speakers remained unchanged (13% Asian, 5% Hispanic/Latinx, 1% Black). In audience feedback forms, female speakers from all sessions were perceived as having equal knowledge base and teaching ability compared with male speakers. However, speakers with <10 years of experience post-training were viewed as less knowledgeable and with poorer teaching abilities compared with more senior faculty. CONCLUSIONS: Gender diversity at inflammatory bowel disease conferences is improving. However, there remain significant gaps, particularly in racial diversity and improving perceptions of early-career speakers. These data should inform program committees for future gastroenterology conferences.

RESUMO

Lingual artery (LA) stenosis or bleeding can be a potentially fatal consequence of stereotactic body radiation therapy of recurrent head and neck cancer. We aim to provide delineation guidelines for LA contouring during head and neck radiation. Three experienced radiation oncologists and 1 radiologist studied the course of LA and its anatomic relationships. A step-by-step guideline was formulated for its delineation on contrast-enhanced axial computed tomography scans. We recommend that LA should be considered an important organ at risk for stereotactic body radiation therapy of head and neck cancer. Its delineation and dose constraints should be considered on a case-to-case basis.

RESUMO

BACKGROUND: Colorectal cancer (CRC) screening can prevent disease by early identification. Existing disparities in CRC screening have been associated with factors including race, socioeconomic status, insurance, and even geography. Our study takes a deeper look into how social determinants related to zip code tabulation areas affect CRC screenings. MATERIALS AND METHODS: We conducted a retrospective cross-sectional study of CRC screenings by race at a zip code level, evaluating for impactful social determinant factors such as the social deprivation index (SDI). We used publicly available data from CDC 500 Cities Project (2016-2019), PLACES Project (2020), and the American Community Survey (2019). We conducted multivariate and confirmatory factor analyses among race, income, health insurance, check-up visits, and SDI. RESULTS: Increasing the tertile of SDI was associated with a higher likelihood of being Black or Hispanic, as well as decreased median household income (P < .01). Lower rates of regular checkup visits were found in the third tertile of SDI (P < .01). The multivariate analysis showed that being Black, Hispanic, lower income, being uninsured, lack of regular check-ups, and increased SDI were related to decreased CRC screening. In the confirmatory factor analysis, we found that SDI and access to insurance were the variables most related to decreased CRC screening. CONCLUSION: Our results reveal the top 2 factors that impact a locality's CRC screening rates are the social deprivation index and access to health care. This data may help implement interventions targeting social barriers to further promote CRC screenings within disadvantaged communities and decrease overall mortality via early screening.

RESUMO

The toxicity of tenofovir alafenamide (TAF) hemifumarate (HF) was evaluated when administered by continuous subcutaneous (s.c.) infusion via an external infusion pump for 28 days to rats and dogs. The toxicokinetics of TAF and two metabolites, tenofovir (TFV) and tenofovir diphosphate (TFV-DP) were also evaluated. After administration of TAF HF in rats and dogs, primary systemic findings supported an inflammatory response that was considered minimal to mild. Gross pathology and histopathologic evaluation of tissue surrounding the s.c. infusion site revealed signs of inflammation, including edema, mass formation, fibrosis, and mononuclear cell inflammation in groups receiving ≥300 µg/kg/day in rats and ≥25 µg/day in dogs. Although these changes were observed in animals receiving vehicle, the severity was greater in animals receiving TAF HF. Changes in the local tissue were considered a TAF HF-mediated exacerbation of an inflammatory response to the presence of the catheter. In rats, systemic and local findings were considered not adverse due to their low severity and reversibility; therefore, the "no observed adverse effect level" (NOAEL) was set at 1,000 µg/kg/day. Because none of the systemic findings were related to systemic exposure to TAF, the systemic NOAEL was set at 250 µg/kg/day in dogs. Due to the severity of the observations noted, a NOAEL for local toxicity could not be established. Although these results might allow for exploration of tolerability and pharmacokinetics of s.c. administered TAF HF in humans, data suggest a local reaction may develop in humans at doses below a clinically relevant dose. IMPORTANCE Human immunodeficiency virus (HIV) infection continues to be a serious global human health issue, with ∼38 million people living with HIV worldwide at the end of 2019. HIV preexposure prophylaxis (PrEP) has introduced the use of antiretroviral therapies as another helpful tool for slowing the spread of HIV worldwide. One possible solution to the problem of inconsistent access and poor adherence to HIV PrEP therapies is the development of subcutaneous (s.c.) depots or s.c. implantable devices that continuously administer protective levels of an HIV PrEP therapy for weeks, months, or even years at a time. We evaluate here the toxicity of tenofovir alafenamide, a potent inhibitor or HIV replication, after continuous s.c. infusion in rats and dogs for HIV PrEP.

RESUMO

BACKGROUND: Stereotactic body radiotherapy (SBRT) is increasingly being performed for hepatocellular cancer and liver metastases. The purpose of this study was to review the practice of SBRT for hepatocellular, pancreatic cancer and liver metastases in India. METHODS: A survey comprising of 25 questions was designed and served to radiation oncology professionals at two major conferences. The survey consisted of 25 multiple choice questions on SBRT infrastructure and caseload, simulation methods and immobilizations, organ motion control methods, simulation and delivery, indications of liver and pancreatic SBRT and prescribed dose. The responses were analyzed using descriptive statistics. RESULTS: From January to June 2017, about 200 professionals were approached and 71 professionals responded with a response rate of 35.5%. The duration of the SBRT practice among respondents was less than 3 years in 53% with 32% having formal training in SBRT. The most common sites for the use of SBRT were lung and brain followed by liver and spine. Liver SBRT was practiced by 29 (59.2%) for hepatic oligometastases, hepatocellular carcinoma (HCC), and cholangiocarcinoma. The most common fractionation used was 50-60 Gy/6 fractions and 45 Gy/3 fractions. Pancreatic SBRT was practiced by 37%, mostly for medically inoperable or locally advanced pancreatic cancer. SBRT was not practiced by 22 (31%) of the respondents, and the main reasons were lack of infrastructure and structured training. CONCLUSION: The SBRT for liver has increased with a usage rate of over 50% amongst respondents. Pancreatic SBRT use is infrequent and limited to inoperable or advanced cases. Lack of infrastructure and training are the main challenges in the routine adaptation of SBRT.

RESUMO

BACKGROUND: Diversity of invited speakers at academic conferences is a topic of increased focus in recent years. While there have been efforts to improve speaker diversity, an evaluation of this in the IBD field has not been undertaken to date. We aimed to address gaps in knowledge of speaker gender, race, and experience at a major annual IBD conference over time. METHODS: AIBD program brochures from 2014 to 2020 were reviewed by two providers to evaluate speaker demographic information including gender, race, topic of discussion, institutional affiliation, and, for those trained in gastroenterology, years post-fellowship. In addition, the proportion of all-male panels was calculated. As a comparator, the proportion of female speakers and all-male panels was then compared to a control conference run by the same CME organization (Personalized Therapies in Thoracic Oncology). RESULTS: The percentage of female speakers of any specialty at AIBD increased from 25% in 2016 to 39% in 2020. Female adult gastroenterologist speakers increased from 12% in 2015 to 27% in 2020. The percentage of all gastroenterologists that are female in the US is 19%. All-male panels also decreased from an average of 47% in 2014-2017, to 11% in 2018-2020. As a comparator, 47% of speakers at the control conference were female and there were no all-male panels in 2020. For race, in any given year an average of 13% of speakers were Asian, 5% Hispanic/Latinx, and 1% Black. This remained static over time. The percentage of Asian, Hispanic/Latinx, and Black gastroenterologists in the US is 29%, 5%, and 6%, respectively. Average years of experience of speakers at AIBD appeared relatively static, with a mean of 15 years since fellowship training per speaker. CONCLUSION: From 2014-2020, the proportion of female speakers at AIBD has increased to over one third in main programming. There remains room for improvement, particularly in increasing the racial and ethnic diversity of speakers and inviting more gastroenterologists in the early stages of their careers.

RESUMO

BACKGROUND: Medically-tailored meal programs that provide home-delivered medically-appropriate food are an emerging intervention when type 2 diabetes co-occurs with food insecurity (limited or uncertain access to nutritious food owing to cost). We sought to understand the experiences of medically-tailored meal program participants. METHODS: We conducted semi-structured interviews with participants in a randomized trial of medically-tailored meals (NCT02426138) until reaching content saturation. Participants were adults (age > 20 years) with type 2 diabetes in eastern Massachusetts, and the interviews were conducted from April to July 2017. Interviews were transcribed verbatim and coded by two independent reviewers. We determined emergent themes using content analysis. RESULTS: Twenty individuals were interviewed. Their mean age was 58 (SD: 13) years, 60.0% were women, 20.0% were non-Hispanic black, and 15.0% were Hispanic. Key themes were 1) satisfaction and experience with medically-tailored meals 2) food preferences and cultural appropriateness, 3) diabetes management and awareness, and 4) suggestions for improvement and co-interventions. Within these themes, participants were generally satisfied with medically-tailored meals and emphasized the importance of receiving culturally appropriate food. Participants reported several positive effects of medically-tailored meals, including improved quality of life and ability to manage diabetes, and stress reduction. Participants suggested combining medically-tailored meals with diabetes self-management education or lifestyle interventions. CONCLUSIONS: Individuals with diabetes and food insecurity expressed satisfaction with the medically-tailored meal program, and reported that participation reduced stress and the burden of diabetes management. Suggestions to help ensure the success of medically-tailored meal programs included a strong emphasis on culturally acceptability and accommodating taste preferences for provided foods, and combining medically-tailored meals with diabetes education or lifestyle intervention. TRIAL REGISTRATION: ClinicalTrials.gov NCT02426138.

RESUMO

Brachytherapy (BT) for locally advanced cervical cancer is vital for optimal outcomes. There is heterogeneity in brachytherapy treatment practice for cervical cancer across India. In an attempt to standardize various processes involved in cervical cancer brachytherapy, the expert members of the Indian Brachytherapy Society (IBS) developed a document related to radiation therapy treatment of cervical cancer with special emphasis on brachytherapy. The guidelines are based on high quality clinical evidence, expert opinion and consensus wherever evidence was lacking. The document provides a guide for external beam radiation and details of all the processes involved in high-dose-rate (HDR) brachytherapy including patient selection, preparation, principles and technique of BT applications, target and normal tissue definition, dose prescriptions, BT planning, reporting parameters, common complications of BT and their management, scope for research, etc. In summary, we present here practical tips and tricks, recording and reporting of cervical cancer brachytherapy, which can be implemented in various clinical environments and forms the basis of this report.

RESUMO

BACKGROUND: Food insecurity, defined as inconsistent food access owing to cost, leads to poor health. OBJECTIVE: To test whether a medically tailored meal delivery program improved dietary quality in individuals with type 2 diabetes and food insecurity. DESIGN: Randomized cross-over clinical trial. PARTICIPANTS: Forty-four adults with diabetes, hemoglobin A1c > 8.0%, and food insecurity (defined as at least one positive item on the two-item "Hunger Vital Sign"). INTERVENTION: In the Community Servings: Food as Medicine for Diabetes cross-over clinical trial (NCT02426138), conducted from June 2015 to July 2017, we randomly assigned the order of "on-meals" (home delivery of 10 meals/week for 12 weeks delivered by Community Servings, a non-profit organization) and "off-meals" (12 weeks usual care and a Choose MyPlate healthy eating brochure) periods. MAIN MEASURES: The primary outcome was Healthy Eating Index 2010 score (HEI), assessed by three 24-h food recalls in both periods. Higher HEI score (range 0-100; clinically significant difference 5) represents better dietary quality. Secondary outcomes included food insecurity and self-reported hypoglycemia. KEY RESULTS: Mean "on-meal" HEI score was 71.3 (SD 7.5) while mean "off-meal" HEI score was 39.9 (SD 7.8) (difference 31.4 points, p < 0.0001). Participants experienced improvements in almost all sub-categories of HEI score, with increased consumption of vegetables, fruits, and whole grains and decreased solid fats, alcohol, and added sugar consumption. Participants also reported lower food insecurity (42% "on-meal" vs. 62% "off-meal," p = 0.047), less hypoglycemia (47% "on-meal" vs. 64% "off-meal," p = 0.03), and fewer days where mental health interfered with quality of life (5.65 vs. 9.59 days out of 30, p = 0.03). CONCLUSIONS: For food-insecure individuals with diabetes, medically tailored meals improved dietary quality and food insecurity and reduced hypoglycemia. Longer-term studies should evaluate effects on diabetes control (e.g., hemoglobin A1c) and patient-reported outcomes (e.g., well-being).

RESUMO

PURPOSE: To investigate dose-response relationship between vaginal doses and long-term morbidity. METHODS AND MATERIALS: Patients receiving adjuvant pelvic (chemo) radiation and brachytherapy for cervical cancer from January 2011 to December 2014 were included. Baseline vaginal length was determined clinically and from imaging at BT planning. Dose points were defined along mucosa and at 5 mm depth at 12, 3, 6, and 9 'o' clock positions at every 2 cm from apex to introitus. Cumulative equivalent doses in 2 Gy were calculated. Vaginal stenosis was reported in reference to baseline length according to CTCAE version 3.0. Receiver operator characteristics curve was used to identify dose thresholds for univariate and multivariate analysis. RESULTS: Overall, 78 women with median age of 49 (32-71) years were included. The median dose at vaginal apex mucosa and 5 mm depth was 118 Gy3 (78-198) and 81 Gy3 (70-149) respectively. At median follow-up of 36 (18-60) months, vaginal stenosis ≥25%, and grade ≥ II telangiectasia was observed in 33.3% and 45.7%, respectively. On receiver operator characteristics analysis, apical mucosal dose >142 Gy3 and recto-vaginal point dose >86 Gy3 predicted for stenosis on univariate (p = 0.02, p = 0.06) and multivariate analysis (p = 0.04). The probability of stenosis increased from 32% at 70 Gy3, 38% at 80 Gy3, and 45% at 90 Gy3 rectovaginal point dose. No correlation was observed between vaginal doses and telangiectasia and vaginal stenosis and sexual quality of life. CONCLUSION: Vaginal apex mucosal dose >142 Gy3 independently predicts for vaginal stenosis.

RESUMO

Drosophila pallidosa belongs to the D. ananassae complex, which includes a total of 10 species. Earlier D. pallidosa was known as light form of D. ananassae but later it was described as a new species, sibling of D. ananassae. Both these terms, light form and sibling species were used by Futch. This makes the taxonomic status of D. pallidosa confusing. In this review we have tried to understand the actual status of this sibling species pair. Considering the similarities and dissimilarities, we suggest that D. pallidosa does not have the full status of a species, rather it is in the process of speciation, statu-nascendi. Our suggestion is strengthened by the fact that male genitalia are identical in both the cases and they lack postmating reproductive isolation since hybrids between them are normal and fully fertile.

RESUMO

PURPOSE: The aim of this study was to study prevalence, risk factors, and morbidity of eyelid laxity in a veteran population. METHODS: This prospective cross-sectional study with a retrospective chart review included 150 subjects evaluated from either an outpatient eye clinic or a geriatric clinic at the Miami Veterans Affairs Hospital from June through August 2013. Clinical data were gathered from a questionnaire and a computerized medical record system including demographics, medical history, and ocular irritation history. Upper and lower eyelid laxity was clinically graded. Main outcome measures were prevalence of eyelid laxity, risk factors for its presence, and its correlation to ocular surface symptoms. RESULTS: Fifty-four percent of participants (n = 81) had laxity (grade 1 or higher) in either upper and/or lower eyelids. Risk factors for eyelid laxity in our population included older age, higher body mass index, and a diagnosis of sleep apnea. Patients with any eyelid laxity (grade 1 or more in any eyelid) had a 2.23-fold risk of severe ocular surface symptoms (score of 12 or higher on the dry eye questionnaire 5) compared with those without laxity (95% confidence interval, 1.15-4.31; P = 0.017), and this was primarily driven by the presence of upper eyelid laxity. CONCLUSIONS: We found high prevalence of eyelid laxity in our population, and its presence was associated with significant ocular surface morbidity. This study reinforces the need to incorporate dynamic eyelid testing into ophthalmic examination in patients with ocular surface discomfort.
