Use of surveillance colonoscopy among individuals with removal of high-risk polyps according to the US Multi-Society Task Force recommendations.

BACKGROUND: Individuals with colorectal polypectomy are recommended to undergo surveillance colonoscopies at certain intervals to prevent subsequent colorectal cancer. Use of postpolypectomy surveillance according to the 2006 US Multi-Society Task Force (USMSTF) recommendations in an integrated health care system was investigated. METHODS: Use of surveillance colonoscopies was prospectively assessed among 3691 patients with removal of high-risk polyps at a screening colonoscopy during 2007-2012 in the Mass General Brigham Colonoscopy Cohort. With the follow-up up to 2017, the compliance with, overuse, and underuse of postpolypectomy surveillance according to the 2006 USMSTF recommendations was assessed. Surveillance use according to demographic factors was also investigated. RESULTS: During a median follow-up of 4.4 years (5th percentile, 95th percentile, 1.0, 9.9) 2360 (64%) patients had undergone a surveillance colonoscopy, among whom 758 (21%) were considered compliant with the USMSTF recommendations. A substantial underuse of surveillance colonoscopies of 62% was observed. Older age and lower income were associated with a higher incidence of underuse, whereas having a family history of colorectal cancer were associated with lower incidence of underuse. Overuse of surveillance colonoscopies was present in 17% of patients but showed no significant associations with demographic factors. CONCLUSION: Substantial underuse of surveillance in patients with high-risk polyps was observed, particularly those with low income and older age. Efforts are needed to improve delivery and use of surveillance colonoscopy. PLAIN LANGUAGE SUMMARY: The US Multi-Society Task Force recommends follow-up surveillance colonoscopy after polyp removal in the bowel, with intervals depending on the most severe findings. Adherence to surveillance recommendations in a large study with up to 10 years of follow-up among patients with high-risk polyps was investigated. Only 21% of patients adhered to the surveillance recommendations, whereas 62% showed delayed or no use of surveillance. Findings highlight the need for improved use of surveillance colonoscopy among patients at high risk of colorectal cancer.

Sexual health indicators for the United States: Measuring progress and documenting public health needs.

Introduction: Today, we are facing increased and continued adverse sexual health outcomes in the United States, including high post-COVID-19 pandemic rates of sexually transmitted infections (STIs). For the past 20 years, there have been calls for a national health strategy and a more comprehensive sexual health approach to address the myriad of persistent sexual health problems in this country. Employing a sexual health approach requires shifting from a longstanding, stigmatizing focus on morbidity toward a holistic and integrated focus on health rather than disease. While strategies are being implemented by multisectoral stakeholders, it is also important to establish a core set of indicators that broadly describe the state of sexual health in the U.S. and allow for measurement across time. The development of a comprehensive scorecard with key sexual health indicators has been proposed by other entities (e.g., Public Health England, World Health Organization), but such an attempt has not been made in the U.S. Methods: A review of national U.S. surveys and surveillance systems with items related to sexual health was conducted for years 2010-2022 to develop an inventory of existing data that yield national estimates for potential indicators of sexual health. Results: We selected 23 sexual health indicators in four broad domains including: (1) knowledge; communication and attitudes (five indicators); (2) behaviors and relationships (four indicators); (3) service access and utilization (seven indicators); and (4) adverse health outcomes (seven indicators). Recent data for each indicator are provided. Discussion: A growing body of evidence shows the positive effects of moving away from a morbidity focus toward an integrated, health-promoting approach to sexual health. Yet, not much has been done in terms of how we implement this national shift. We argue that measurement and monitoring are key to future change. We envision these core sexual health indicators would be published in the form of an index that is publicly available and updated frequently. These sexual health indicators could be used for ongoing monitoring, and to guide related research, programming, and policy development to help promote sexual health in coming years.

Prevalence of ocular findings regardless of visual acuity status in older adults from the Brazilian Amazon Region.

Recently, it has been recommended that population-based studies report not only frequencies of vision impairment and blindness but also any ocular abnormalities that might lead an individual to seek for eyecare services. The current study aimed to determine prevalence of ocular findings regardless of visual acuity (VA) status in older adults from the Brazilian Amazon Region. Disturbances were grouped into: Eyelids; Anterior Segment; Posterior Segment; Increased intraocular pressure; and Overall Globe. The presence of an ocular finding was considered positive when any abnormality was noted, regardless of VA. Refractive errors were not considered. A total 2384 eligible persons were enumerated and 2041 (85.6%) examined. The prevalence of ocular disturbances in either eye was 87.0% and was associated with male gender, older age, lower education, and rural residence. Overall, main findings were pterygium, cataract, and pinguecula, occurring in 58.8%, 45.4% and 17.4%, respectively. Among individuals with 20/20 VA in both eyes, the most frequent findings were pterygium, pinguecula, and glaucoma cupping, occurring in 47.4%, 31.2% and 6.5%, respectively. The high prevalence of ocular findings observed in this population reinforces that different conditions might not immediately decrease VA but can indicate risk and/or discomfort symptoms and should be considered when planning public health ophthalmic services.

Validity of predictive equations for 24-h urinary sodium excretion at the population and individual levels among Chinese adults aged 18-69 years.

Spot urine (SU) collection is a convenient method commonly used for sodium estimation, but its validity in predicting 24-h urinary sodium (24-hUNa) excretion has not been thoroughly evaluated among the general population. The aim of this study was to comprehensively assess the validity of eight existing methods in predicting 24-hUNa excretion by using SU samples among Chinese adults. We analyzed 1424 representative individuals aged 18 to 69 years. We compared the measured and estimated measurements of 24-hUNa at the population level by examining bias, the correlation, intraclass correlation coefficients (ICCs), receiver operating characteristic (ROC) curves and Bland-Altman plots and analyzed the relative and absolute differences and misclassification at the individual level. The bias for all methods was significant (all p < 0.001), among which the smallest bias was - 7.9 mmol for the Toft formula and the largest bias was - 53.8 mmol for the Mage formula. Correlation coefficients were all less than 0.380, all formulas exhibited an area under the ROC curve below 0.683, and the Bland-Altman plots indicated slightly high dispersion of the estimation biases at higher sodium levels regardless of the formula. The proportions of relative differences > 40% for the eight methods were all over one-third, the proportions of absolute differences > 51.3 mmol/24 h (3 g/day NaCl) were all over 40%, and the misclassification rates (7, 10, and 13 g/day NaCl as cutoff points) were all over 65%. Caution remains due to poor validity between estimated and actual measurements when using the eight formulas to obtain a plausible estimation for surveillance of the Chinese population sodium excretion, and the results do not support the application of SU to estimate sodium intake at the individual level due to its poor performance with respect to classification.

Sarcopenia risk and associated factors among Chinese community-dwelling older adults living alone.

Sarcopenia, defined as a progressive loss of muscle mass and reduced muscle strength and functional capacity, is common among older adults. This study aimed to assess the proportion of people at risk of sarcopenia and probable sarcopenia among Chinese community-dwelling older adults living alone and to identify the associated factors. A total of 390 older adults were included in this study. Sarcopenia and probable sarcopenia were defined according to the criteria of the Asian Working Group for Sarcopenia 2019. Data on socio-demographic characteristics, health status, health behaviours and lifestyle characteristics, nutritional status, physical activity level, and depressive symptoms were collected. The association between these characteristics and sarcopenia risk was analysed using a multivariate ordinal logistic regression. The proportion of subjects at risk of sarcopenia and probable sarcopenia was found to be 57.7% and 30%, respectively. Older age, being malnourished and being at risk of malnutrition were significantly associated with sarcopenia risk. Being educated to secondary level or above, being overweight or obese and higher physical activity level were associated with decreased sarcopenia risk. Our results showed that older adults living alone were at high risk of developing sarcopenia and probable sarcopenia. These results emphasise the urgent need to initiate aggressive screening and holistic lifestyle therapeutic intervention strategies for this high-risk population.

Prevalence of depressive disorders and treatment in China: a cross-sectional epidemiological study.

BACKGROUND: In China, depressive disorders have been estimated to be the second leading cause of years lived with disability. However, nationally representative epidemiological data for depressive disorders, in particular use of mental health services by adults with these disorders, are unavailable in China. The present study, part of the China Mental Health Survey, 2012-15, aims to describe the socioeconomic characteristics and the use of mental health services in people with depressive disorders in China. METHODS: The China Mental Health Survey was a cross-sectional epidemiological survey of mental disorders in a multistage clustered-area probability sample of adults of Chinese nationality (≥18 years) from 157 nationwide representative population-based disease surveillance points in 31 provinces across China. Trained investigators interviewed the participants with the Composite International Diagnostic Interview 3.0 to ascertain the presence of lifetime and 12-month depressive disorders according to DSM-IV criteria, including major depressive disorder, dysthymic disorder, and depressive disorder not otherwise specified. Participants with 12-month depressive disorders were asked whether they received any treatment for their emotional problems during the past 12 months and, if so, the specific types of treatment providers. The Sheehan Disability Scale (SDS) was used to assess impairments associated with 12-month depressive symptoms. Data-quality control procedures included logic check by computers, sequential recording check, and phone-call check by the quality controllers, and reinterview check by the psychiatrists. Data were weighted according to the age-sex-residence distribution data from China's 2010 census population survey to adjust for differential probabilities of selection and differential response, as well as to post-stratify the sample to match the population distribution. FINDINGS: 28 140 respondents (12 537 [44·6%] men and 15 603 [55·4%] women) completed the survey between July 22, 2013, and March 5, 2015. Ethnicity data (Han or non-Han) were collected for only a subsample. Prevalence of any depressive disorders was higher in women than men (lifetime prevalence odds ratio [OR] 1·44 [95% CI 1·20-1·72] and 12-month prevalence OR 1·41 [1·12-1·78]), in unemployed people than employed people (lifetime OR 2·38 [95% CI 1·68-3·38] and 12-month OR 2·80 [95% CI 1·88-4·18]), and in people who were separated, widowed, or divorced compared with those who were married or cohabiting (lifetime OR 1·87 [95% CI 1·39-2·51] and 12-month OR 1·85 [95% CI 1·40-2·46]). Overall, 574 (weighted % 75·9%) of 744 people with 12-month depressive disorders had role impairment of any SDS domain: 439 (83·6%) of 534 respondents with major depressive disorder, 207 (79·8%) of 254 respondents with dysthymic disorder, and 122 (59·9%) of 189 respondents with depressive disorder not otherwise specified. Only an estimated 84 (weighted % 9·5%) of 1007 participants with 12-month depressive disorders were treated in any treatment sector: 38 (3·6%) in speciality mental health, 20 (1·5%) in general medical, two (0·3%) in human services, and 21 (2·7%) in complementary and alternative medicine. Only 12 (0·5%) of 1007 participants with depressive disorders were treated adequately. INTERPRETATION: Depressive disorders in China were more prevalent in women than men, unemployed people than employed, and those who were separated, widowed, or divorced than people who were married or cohabiting. Most people with depressive disorders reported social impairment. Treatment rates were very low, and few people received adequate treatment. National programmes are needed to remove barriers to availability, accessibility, and acceptability of care for depression in China.

Process evaluation of integrated West Nile virus surveillance in northern Italy: an example of a One Health approach in public health policy.

West Nile virus (WNV) is endemic in the Po valley area in northern Italy. Regional health authorities have implemented integrated WNV surveillance following a One Health approach, based on collaboration between human, animal and environmental health institutions. We evaluated this integrated WNV surveillance system in Emilia-Romagna, Lombardy and Piedmont regions by means of a process evaluation. We examined the system's implementation fidelity, dose delivered and received, reach, and we identified strengths and weaknesses in the system. Qualitative and semi-quantitative data were obtained from three regional focus groups. Data were discussed in a follow up focus group, where participants suggested recommendations for improving the surveillance system. Inter-institutional and interdisciplinary integration and the creation of a 'community of practice' were identified as key elements for effective surveillance. We identified differences in the degree of interdisciplinary integration in the three regions, likely due to different epidemiological situations and years of experience in surveillance implementation. Greater collaboration and sharing of information, public engagement and economic assessments of the integrated surveillance approach would facilitate its social recognition and guarantee its sustainability through dedicated funding. We demonstrate that a transdisciplinary research approach based on process evaluation has value for designing and fine-tuning integrated health surveillance systems.

Understanding the Clinical Implications of Low Penetrant Genes and Breast Cancer Risk.

OPINION STATEMENT: Since the 2013 Supreme Court declaration, panel testing for hereditary cancer syndromes has evolved into the gold standard for oncology germline genetic testing. With the advent of next-generation sequencing, competitive pricing, and developing therapeutic options, panel testing is now well integrated into breast cancer management and surveillance. Although many established syndromes have well-defined cancer risks and management strategies, several breast cancer genes are currently classified as limited-evidence genes by the National Comprehensive Cancer Network (NCCN). Follow-up for individuals with mutations in these genes is a point of contention due to conflicting information in the literature. The most recent NCCN guidelines have stratified management based on gene-specific cancer risks indicating that expanding data will allow for better recommendations as research progresses. The evolving management for these genes emphasizes the clinicians' need for evidence-based understanding of low penetrance breast cancer genes and their implications for patient care. This article reviews current literature for limited evidence genes, detailing cancer risks, association with triple-negative breast cancer, and recommendations for surveillance. A brief review of the challenges and future directions is outlined to discuss the evolving nature of cancer genetics and the exciting opportunities that can impact management.

Vitamin D Nutritional Status of Chinese Pregnant Women, Comparing the Chinese National Nutrition Surveillance (CNHS) 2015-2017 with CNHS 2010-2012.

Optimal vitamin D (vitD) status is beneficial for both pregnant women and their newborns. The aim of this study was to evaluate the vitamin D status of Chinese pregnant women in the latest China Nutrition and Health Surveillance (CNHS) 2015-2017, analyze the risk factors of vitamin D deficiency (VDD), and compare them with those in CNHS 2010-2012. Serum 25 hydroxyvitamin D (25(OH)D) was measured by ELISA method. City type, district, latitude, location, age, vitamin D supplements intake, education, marital status, annual family income, etc., were recorded. The median 25(OH)D concentration was 13.02 (10.17-17.01) ng/mL in 2015-2017, and 15.48 (11.89-20.09) ng/mL in 2010-2012. The vitamin D sufficient rate was only 12.57% in 2015-2017, comparing to 25.17% in 2010-2012. The risk factors of vitamin D inadequacy (25(OH)D < 20 ng/mL) in 2015-2017 were not exactly consistent with that in 2010-2012. The risk factors included season of spring (p < 0.0001) and winter (p < 0.001), subtropical (p < 0.001), median (p < 0.0001) and warm temperate zones (p < 0.0001), the western (p = 0.027) and the central areas (p = 0.041), while vitD supplements intake (p = 0.021) was a protective factor in pregnant women. In conclusion, vitD inadequacy is very common among Chinese pregnant women. We encourage pregnant women to take more effective sunlight and proper vitD supplements, especially for those from the subtropical, warm and medium temperate zones, the western and the central, and in the seasons of spring and winter.

Probabilistic modelling techniques in dietary exposure assessment: application on the risk assessment of cadmium for Austrian adults.

Probabilistic exposure and risk assessment of chemical hazards in the diet have increasingly gained ground in recent years as a pragmatic approach for the approximation of reality. This work presents the outcomes of a project which aimed at applying probabilistic techniques for basic modelling of chronic dietary exposure to food contaminants following EFSA guidance. These techniques, based on Monte Carlo Risk Assessment (MCRA) software and on the programming language R, were employed for the risk assessment of cadmium for Austrian adults, enabling the validation and the critical comparison of the two approaches. Harmonisation and optimisation of procedures, refinement of exposure assessment skills and confidence in the results were the main benefits. Data amount and validity were identified as critical parameters, influencing the precision of the results. Cadmium was selected as a case study due to its toxicological properties, its ubiquitous presence in food and the availability of Austrian occurrence data. Similar exposure and risk estimates were generated through MCRA and R in alternative optimistic and pessimistic exposure scenarios, suggesting low levels of concern, except for vegetarians, whose upper tail exposures are close to the established Tolerable Weekly Intake. However, as occurrence data gaps have been identified as the major element of uncertainty, the estimated exposure and risk levels are characterised as underestimated. Grains and grain-based products, potatoes and leafy vegetables are the main contributors to the intake. The results will contribute to risk management and to a future refinement of the assessment.

Optimization of prediction methods for risk assessment of pathogenic germline variants in the Japanese population.

Predicting pathogenic germline variants (PGVs) in breast cancer patients is important for selecting optimal therapeutics and implementing risk reduction strategies. However, PGV risk factors and the performance of prediction methods in the Japanese population remain unclear. We investigated clinicopathological risk factors using the Tyrer-Cuzick (TC) breast cancer risk evaluation tool to predict BRCA PGVs in unselected Japanese breast cancer patients (n = 1,995). Eleven breast cancer susceptibility genes were analyzed using target-capture sequencing in a previous study; the PGV prevalence in BRCA1, BRCA2, and PALB2 was 0.75%, 3.1%, and 0.45%, respectively. Significant associations were found between the presence of BRCA PGVs and early disease onset, number of familial cancer cases (up to third-degree relatives), triple-negative breast cancer patients under the age of 60, and ovarian cancer history (all P < .0001). In total, 816 patients (40.9%) satisfied the National Comprehensive Cancer Network (NCCN) guidelines for recommending multigene testing. The sensitivity and specificity of the NCCN criteria for discriminating PGV carriers from noncarriers were 71.3% and 60.7%, respectively. The TC model showed good discrimination for predicting BRCA PGVs (area under the curve, 0.75; 95% confidence interval, 0.69-0.81). Furthermore, use of the TC model with an optimized cutoff of TC score ≥0.16% in addition to the NCCN guidelines improved the predictive efficiency for high-risk groups (sensitivity, 77.2%; specificity, 54.8%; about 11 genes). Given the influence of ethnic differences on prediction, we consider that further studies are warranted to elucidate the role of environmental and genetic factors for realizing precise prediction.

Pathogenesis of Keratinocyte Carcinomas and the Therapeutic Potential of Medicinal Plants and Phytochemicals.

Keratinocyte carcinoma (KC) is a form of skin cancer that develops in keratinocytes, which are the predominant cells present in the epidermis layer of the skin. Keratinocyte carcinoma comprises two sub-types, namely basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). This review provides a holistic literature assessment of the origin, diagnosis methods, contributing factors, and current topical treatments of KC. Additionally, it explores the increase in KC cases that occurred globally over the past ten years. One of the principal concepts highlighted in this article is the adverse effects linked to conventional treatment methods of KC and how novel treatment strategies that combine phytochemistry and transdermal drug delivery systems offer an alternative approach for treatment. However, more in vitro and in vivo studies are required to fully assess the efficacy, mechanism of action, and safety profile of these phytochemical based transdermal chemotherapeutics.

Decreasing transmission and initiation of countrywide vaccination: Key challenges for future management of COVID-19 pandemic in Bangladesh.

With a fragile healthcare system, Bangladesh, much like other countries in South East Asia, struggled during the early days of COVID-19 pandemic. In following months several encouraging initiatives were undertaken including nationwide lockdown, maintaining social distancing and setting up COVID-19 dedicated laboratories and hospitals. Despite fear of an escalation in COVID-19 transmission during the winter months like their European counterparts, fortunately infection rates subsided and Bangladesh came out largely unharmed. But the next phase of COVID-19 pandemic management that includes viral transmission suppression and conduction of nationwide immunization program require several urgent steps from government of Bangladesh (GoB) and relevant stakeholders. This qualitative research piece discussed about issues including an urgent need to enhance critical care facilities around the country, especially in peripheral districts; ramping up COVID-19 testing at existing laboratories in view of diagnosing each case, and ensuring vaccines for the vulnerable populations in the country. Furthermore, the researchers shed light on other issues including a need to reinforce a struggling healthcare workforce, encouraging people to take vaccine, proper maintenance of social distancing regulations, routine epidemiological surveillance, management of environment and biomedical waste and undertaking a holistic approach to combat the pandemic and its environmental and financial consequences.

Impact of MASP2 gene polymorphism and gene-tea drinking interaction on susceptibility to tuberculosis.

Mannan-binding lectin-associated serine protease-2 (MASP-2) has been reported to play an important role as a key enzyme in the lectin pathway of the complement system. The objectives of our study were to determine whether the single-nucleotide polymorphism (SNPs) of MASP2 and the gene-tea drinking interaction were associated with the susceptibility to TB. In total, 503 patients and 494 healthy controls were contained. Three SNPs (rs12142107, rs12711521, and rs7548659) were genotyped. The association between the SNPs and susceptibility to TB were investigated by conducting multivariate unconditional logistic regression analysis. The gene-tea drinking interactions were analyzed by the additive model of marginal structural linear odds models. Both genotype AC + AA at rs12711521 of MASP2 genes and genotype GT + GG at rs7548659 of MASP2 genes were more prevalent in the TB patient group than the healthy control group (OR: 1.423 and 1.439, respectively, P < 0.05). In addition, The relative excess risk of interaction (RERI) between tea drinking and rs12142107, rs12711521, and rs7548659 of MASP2 genes was found to suggest negative interactions, which reached - 0.2311 (95% confidence interval (CI): - 0.4736, - 0.0113), - 0.7080 (95% CI - 1.3998, - 0.0163), and - 0.5140 (95% CI - 0.8988, - 0.1291), respectively (P < 0.05). Our finding indicated that the SNPs (rs12711521 and rs7548659) of MASP2 were associated with the susceptibility to TB. Furthermore, there were negative interactions between tea drinking and rs12142107, rs12711521, and rs75548659 of MASP2 gene, respectively. Our research provides a basis for studying the pathogenesis and prevention of tuberculosis.

Pharmacy based surveillance for identifying missing tuberculosis cases: A mixed methods study from South India.

BACKGROUND: No Indian studies have assessed the implementation of recent policy on pharmacy based surveillance and its contribution in TB notification. So, this study was conducted with objectives to describe: a) pharmacy based TB surveillance and TB notification, and b) experiences of pharmacy based surveillance implementation from the programme managers and pharmacists perspective. METHODS: A mixed methods study-quantitative (cross-sectional) and qualitative (in-depth interviews) in two selected districts Dharmapuri and Salem districts of Tamil Nadu State, India. RESULTS: In 2018, 45 (11%) of 397 pharmacies in Dharmapuri and 90 (6%) of 1457 pharmacies in Salem districts reported sale of anti-TB drugs to 1307 and 1673 persons respectively. Upon validation through direct patient contact 942 (72%) persons in Dharmapuri and 863 (52%) persons were identified as previously 'un-notified' TB patients. These patients constituted 20% and 29% of the total TB cases notified in Dharmapuri and Salem respectively. The enablers for implementing this activity were: understanding the importance of notification, availability of resources (manpower, computers) to record, report and validate the patient data, repeated trainings and partnerships. The barriers were: patients' hesitancy to share their details to pharmacists (confidentiality), cumbersome recording and reporting process, difficulties in recording patient details during high workload busy business hours. CONCLUSION: This process contributed about one-fourth of the TB patients notified in these districts. Its implementation needs to be strengthened and should be scaled up in other parts of the country.

Exploring Contextual Factors Associated with Suicide among Older Male Farmers: Results from the CDC NVDRS Dataset.

Objectives: The purpose of this study was to explore how demographic, relationship, mental health, and life stressors are associated with suicide among older male farmers and to determine if these differ by age.Methods: We conducted exploratory analyses with Centers for Disease Control (CDC) National Violent Death Reporting System (NVDRS) 2003-2017 dataset. We identified individuals who completed suicide while working in agriculture (N = 2,106). We explored descriptive statistics for farmers who completed suicide and compared these by age using chi-square tests.Results: The majority of the sample was male, non-Hispanic, and White. Marital status differed significantly by age, with older farmers more likely to be married or widowed. Having a mental health issue was not statistically significant by age; however, depression was most prevalent among those 65+. Older farmers who completed suicide were also significantly more likely to report physical health problems.Conclusions: Results illustrate the vulnerability of individuals contemplating suicide and emphasize the need to consider the phenomenon from a holistic perspective that accounts for individuals nested within community.Clinical implications: We recommend health providers consider a systems approach to suicide prevention as our results indicate individual, familial, and societal factors contributing to the incidence of suicide completion among older farmers.

Association between daily and non-daily cannabis use and depression among United States adult cancer survivors.

BACKGROUND: Cancer survivors are vulnerable to Cannabis Use (CU) and at increased risk for depression. Yet, the relationship between CU and depression among cancer survivors is unknown. PURPOSE: The purpose of this study was to estimate the prevalence of daily/non-daily CU, investigate the association between CU and depression and evaluate CU reasons and methods of administration among cancer survivors. METHOD: Population-based, nationally representative sample of cancer survivors aged ≥18 (n = 10,799) from 2018 Behavioral Risk Factor Surveillance System Survey was used. Weighted descriptive statistics and multivariate logistic regression were conducted. FINDINGS: Overall, 4.2% reported daily and 4.1% non-daily CU. Those who self-reported depression had higher prevalence of daily and non-daily CU than those not reporting depression. Daily CU was associated with 120% increased odds of depression (odds ratio = 2.2, 95% confidence interval [1.3, 3.7]) compared with none-users. DISCUSSION: Efforts to improve open communications and evidence-informed discussions regarding benefits and risks of CU and reasons for using cannabis between clinicians and cancer survivors are imperative.

Access to Lung Cancer Screening in the Veterans Health Administration: Does Geographic Distribution Match Need in the Population?

BACKGROUND: Studies show uneven access to Medicare-approved lung cancer screening (LCS) programs across the United States. The Veterans Health Administration (VA), the largest national US integrated health system, is potentially well positioned to coordinate LCS services across regional units to ensure that access matches distribution of need nationally. RESEARCH QUESTION: To what extent does LCS access (considering both VA and partner sites) and use match the distribution of eligible Veterans at state and regional levels? METHODS: In this retrospective analysis, we identified LCS examinations in VA facilities between 2013 and 2019 from the VA Corporate Data Warehouse and plotted VA facilities with LCS geographically. We compared estimated LCS rates (unique Veterans screened per LCS-eligible population) across states and VA regional units. Finally, we assessed whether the VA's new partnership with the GO2 Foundation for Lung Cancer (which includes more than 750 LCS centers) closes geographic gaps in LCS access. RESULTS: We identified 71,898 LCS examinations in 96 of 139 (69.1%) VA facilities in 44 states between 2013 and 2019, with substantial variation across states (0-8 VA LCS facilities per state). Screening rates among eligible Veterans in the population varied more than 30-fold across regional networks (rate ratio, 33.6; 95% CI, 30.8-36.7 for VA New England vs Veterans Integrated Service Network 4), with weak correlation between eligible populations and LCS rates (coefficient, -0.30). Partnering with the GO2 Foundation for Lung Cancer expands capacity and access (eg, all states now have ≥ 1 VA or partner LCS site), but 9 of the 12 states with the highest proportions of rural Veterans still have ≤ 3 total LCS facilities. INTERPRETATION: Disparities in LCS access exist based on where Veterans live, particularly for rural Veterans, even after partnering with the GO2 Foundation for Lung Cancer. The nationally integrated VA system has an opportunity to leverage regional resources to distribute and coordinate LCS services better to ensure equitable access.

Thiamine fortification strategies in low- and middle-income settings: a review.

Thiamine (vitamin B1 ) is an essential micronutrient in energy metabolism and cognitive and neurological health. Thiamine deficiency disorders (TDDs) have a range of clinical presentations that result in various morbidities and can be fatal if not promptly recognized and treated, especially in infants. To intervene, thiamine intakes by breastfeeding mothers and others at risk of thiamine deficiency should be increased to ensure adequate thiamine intake. Although thiamine fortification programs have a long history in high-income countries, there are few mandatory fortification programs to address TDDs in low- and middle-income countries (LMICs), particularly in the regions of greatest concern, South and Southeast Asia. This review highlights essential aspects for consideration in the development of a mandatory fortification program in LMICs, including an overview of the data required to model fortification dosing schemes, available thiamine fortificants, and potential fortification vehicles, as well as identifies current knowledge gaps.
