Addressing differences in cancer: a framework for synergistic programming in cancer prevention and control.

Background: Cancer remains a leading cause of death worldwide and continues to disproportionately impact certain populations. Several frameworks have been developed that illustrate the multiple determinants of cancer. Expanding upon the work of others, we present an applied framework for cancer prevention and control designed to help clinicians, as well as public health practitioners and researchers, better address differences in cancer outcomes. Methods: The framework was developed by the Cancer Prevention and Control Research Network's Health Behaviors Workgroup. An initial framework draft was developed based on workgroup discussion, public health theory, and rapid literature review on the determinants of cancer. The framework was refined through interviews and focus groups with Federally Qualified Health Center providers (n=2) and cancer patients (n=2); participants were asked to provide feedback on the framework's causal pathways, completeness, and applicability to their work and personal life. Results: The framework provides an overview of the relationships between sociodemographic inequalities, social and structural determinants, and key risk factors associated with cancer diagnosis, survivorship, and cancer morbidity and mortality across the lifespan. The framework emphasizes how health-risk behaviors like cigarette smoking interact with psychological, psychosocial, biological, and psychosocial risk factors, as well as healthcare-related behavior and other chronic diseases. Importantly, the framework emphasizes addressing social and structural determinants that influence health behaviors to reduce the burden of cancer and improve health equity. Aligned with previous theory, our framework underscores the importance of addressing co-occurring risk factors and disease states, understanding the complex relationships between factors that influence cancer, and assessing how multiple forms of inequality or disadvantage intersect to increase cancer risk across the lifespan. Conclusions: This paper presents an applied framework for cancer prevention and control to address cancer differences. Because the framework highlights determinants and factors that influence cancer risk at multiple levels, it can be used to inform the development, implementation, and evaluation of interventions to address cancer morbidity and mortality.

Losing a part of life: experiences of cancer survivors accessing treatment and sheltering in place during the COVID-19 pandemic.

PURPOSE: To explore experiences of sheltering in place and accessing treatment during the initial stages of the COVID-19 pandemic among survivors with cancer receiving tyrosine kinase inhibitor (TKI) therapy. METHODS: Participants from two pilot studies evaluating TKI therapy use in the Southeastern United States during the start of the COVID-19 pandemic (March 2020) were interviewed. Identical interview guides were used across both studies to assess participants' experiences accessing cancer treatment, sheltering in place, and coping during the COVID-19 pandemic. Digitally recorded sessions were transcribed professionally and checked for accuracy. Descriptive statistics were used to summarize participant sociodemographics, and a six-step thematic approach was used to analyze interview data and identify salient themes. Dedoose qualitative research software was used to manage and organize qualitative codes, themes, and memos. RESULTS: Participants (n = 15) ranged from 43 to 84 years of age, and were mostly female (53.3%), married (60%), and survivors with hematologic malignancies (86.7%). The research team identified five salient themes: Participants followed pandemic guidelines, Variable impact on well-being, Common feelings of fear, anxiety and anger, No barriers to accessing therapy and medical care, and Faith and God as powerful forces for coping. CONCLUSIONS: The conclusions of the study provide several implications for survivorship programs or clinics for supporting survivors who are taking chronic TKI therapy during COVID-19, including enhancement of current psychosocial support efforts for cancer survivors or development of new programs tailored to the unique needs of a survivor during a pandemic, such as focused coping strategies, modified physical activity programs, family/professional role changes, and access to safe public spaces.

Longitudinal assessment of nonavalent vaccine HPV types in a sample of sexually active African American women from ten U.S. Cities.

BACKGROUND: Chronic infection with high-risk human papillomavirus is a necessary cause for cervical carcinogenesis. This study examined prevalence of nonavalent vaccine preventable HPV types over four months among sexually active women in the United States. METHODS: This sub-study obtained meta-data for 80 of the 1,365 women (18-25 years), enrolled in the BRAVO study, a randomized, open-label trial of home screening and treatment of asymptomatic bacterial vaginosis at high-risk for sexually transmitted infections conducted between 2008 and 2013. Participants were randomized to treatment or standard-of-care, and followed every 2-months for 12 months. Stored vaginal swabs from the first three visits were tested for the nine vaccine preventable HPV types using quantitative PCR. Prevalence and associated 95% confidence intervals for the HPV types were assessed using R (version 3.6.1). RESULTS: The average age of the participants was 21.5 (SD ± 2.11) years, with 60% having ever been pregnant and all were African-American. Majority (71%) reported ≥ two sex partners in the prior year with 89% having unprotected vaginal sex and 45% having a new sex partner in the prior year. About 30% had ≥ one of the nine nonavalent vaccine HPV types at all three time points over a period of four months, 15% at two of any three visits, 19% at one of the three visits and 36% were negative for all nine vaccine HPV types at all time points. The most frequently detected HPV vaccine types were 52, 58, 16, and 18. The prevalence of any vaccine HPV types, and high-risk HPV types was 63.8% and 58.8%, respectively. CONCLUSIONS: Our findings suggest that HPV vaccination which is currently recommended for all unvaccinated persons through age 26 years, is likely to be more beneficial than previously thought as nonavalent HPV vaccine was not available during the time these data were collected.

HIV/HCV coinfection and the risk of cardiovascular disease: A meta-analysis.

The emergence of improved antiretroviral therapy has increased the life expectancy of human immunodeficiency virus (HIV)-infected individuals, although there is an increased susceptibility to developing cardiovascular diseases (CVD). The risk for CVD is purported to be even higher among people with HIV and hepatitis C virus (HCV) coinfection because of the increased inflammatory response, which may synergistically impact CVD risk. However, studies comparing CVD outcomes between HIV alone and HIV/HCV individuals have been discordant. Accordingly, we conducted a meta-analysis to clarify and quantify the association between HIV/HCV coinfection and the risk for CVD. We searched EMBASE, CINAHL, Google Scholar, PubMed, and Web of Science from inception to December 2016 to identify studies that provided information on HIV/HCV coinfection and CVD, defined as coronary artery disease, congestive heart failure and stroke. We used a random-effects model to abstract and pool data on the hazard ratios (HRs) for CVD. HRs were adjusted for traditional CVD risk factors including age, sex, smoking, hypertension, diabetes and LDL cholesterol. Among the 283 articles reviewed, four cohort studies met inclusion criteria with a total of 33 723 participants. The pooled adjusted HRs for the association between HIV/HCV coinfection and CVD were 1.24 (95% CI: 1.07-1.40) compared to HIV monoinfection. The test for heterogeneity was not statistically significant (I2 =0.0%, P=.397). In conclusion, individuals with HIV/HCV coinfection had an increased CVD risk compared to those with HIV monoinfection. More research is needed to further examine the nature of this association, and response to traditional risk-reduction therapies.

The relationship between helminth infections and low haemoglobin levels in Ethiopian children with blood type A.

The current study was conducted to evaluate the nature of association of ABO blood type with helminth infection and related reduction in haemoglobin concentration. Stool samples were collected from 403 school-age children attending Tikur Wuha Elementary School from February to April 2011. Helminth infection was examined using formol-ether concentration and thick Kato-Katz (two slides per stool specimen) techniques. Haemoglobin level was determined using a HemoCue machine and ABO blood type was determined using the antisera haemagglutination test. Nutritional status was assessed using height and weight measurements. Out of 403 children examined, 169, 120, 96 and 18 had blood type O, A, B and AB, respectively. The prevalences of helminth infections were 46.9% for hookworm, 24.6% for Schistosoma mansoni, 4.2% for Ascaris lumbricoides, 1.7% for Trichuris trichiura and 58.3% for any helminth species. The relative odds of infection with at least one helminth species was significantly higher among children with blood type A (adjusted odds ratio (AOR), 2.10; 95% confidence interval (CI), 1.28-3.45) or blood type B (AOR, 2.08; 95% CI, 1.22-3.56) as compared to children with blood type O. Among children infected with helminths, mean haemoglobin concentration was lower in those with blood type A than those with blood type O (ß, -0.36; 95% CI, -0.72 to -0.01). The relative odds of hookworm infection (AOR, 1.78; 95% CI, 1.08-2.92) and related reduction in haemogobin levels (ß, -0.45; 95% CI, -0.84 to -0.04) was higher among children with blood type A as compared to those with blood type O. Although the difference was not significant, the relative odds of S. mansoni or A. lumbricoides infections and related reduction in haemoglobin levels was also higher in children with blood type A or B as compared to children with blood type O. In conclusion, children with blood type A are associated with an increased risk of helminth, particularly hookworm, infection and related reduction in haemoglobin level. The mechanisms by which blood type A makes children susceptible to helminth infection and a related reduction in haemoglobin level ought to be investigated.

Perception, intention and attempts to quit smoking among Jordanian adolescents from the Irbid Longitudinal Study.

OBJECTIVE: To describe important tobacco cessation indicators among adolescent smokers from Irbid, Jordan. METHODS: Participants for this study were selected from the Irbid Longitudinal Study of Smoking Behaviour (20082011). A total of 1781 students were enrolled at baseline from 19 of 60 randomly selected schools (participation rate 95%). Only students who reported current smoking at baseline were included in the study (n = 605). RESULTS: Among the study participants, 74.3% wanted to quit smoking, 64.2% tried to quit and 68% believed it was easy to quit at any time. Attempts to quit smoking were significantly more frequent among boys than among girls for cigarettes (boys 72% vs. girls 45.2%) and waterpipes (boys 71.7% vs. girls 53.5%). More girls (55.2%) than boys (28.6%) wanted to quit waterpipe smoking because they believed that it was harmful to health (P 0.001) and because smoking among children was unacceptable to their families (P = 0.003). CONCLUSIONS: Most of the students in this cohort wanted and tried to quit smoking. They believed it was easy to quit smoking whenever they wanted. Health concerns in boys and girls, and family opposition to smoking among girls were barriers to continued smoking.

Waterpipe a gateway to cigarette smoking initiation among adolescents in Irbid, Jordan: a longitudinal study.

SETTING: According to anecdotal evidence, waterpipe smoking may lead to the initiation of cigarette smoking among young people. This hypothesis is yet to be examined using an appropriate study design and a theoretical model for behavioral change. OBJECTIVE: To compare the risk of cigarette smoking initiation among waterpipe-only smokers and never smokers in a school-based sample of adolescents from Irbid, Jordan. METHODS: A total of 1454 cigarette-naïve participants were drawn from a longitudinal study on smoking behavior conducted in Irbid among 1781 seventh graders who were enrolled at baseline (2008) and completed the study questionnaire on smoking behavior annually until 2011. Grouped time-survival analysis was used to compare the risk of subsequent initiation of cigarette smoking between waterpipe smokers (n = 298) and never smokers (n = 1156) using adjusted hazard ratios (aHRs) and 95% confidence intervals (95%CI). RESULTS: Risk of initiation of cigarette smoking among waterpipe smokers was significantly higher than among never smokers after adjusting for potential confounders (aHR 1.67, 95%CI 1.46-1.92). The association between waterpipe and cigarette smoking initiation was dose-dependent. The risk of initiating cigarette smoking increased with increase in the frequency of waterpipe smoking (P for linear trend < 0.001). CONCLUSIONS: Waterpipe smoking led to the initiation of cigarette smoking among this cohort of Jordanian adolescents; the effect was dose-dependent.

Prevalence and correlates of bacterial vaginosis among young women of reproductive age in Mysore, India.

PURPOSE: Bacterial vaginosis (BV) is the most common cause of abnormal vaginal discharge among women of childbearing age and is associated with STI/HIV and adverse birth outcomes. The objective of this study was to determine the prevalence and correlates of BV among young women of reproductive age in Mysore, India. METHODS: Between October 2005 and December 2006, 898 sexually active women of 15-30 years of age were enrolled from two reproductive health clinics in Mysore. The women underwent an interview followed by physical examination, HSV-2 serologic testing, endocervical culture for Neisseria gonorrhoeae , and vaginal swabs for diagnosis of BV, Trichomonas vaginalis infection and candidiasis. Statistical analyses included conventional descriptive statistics and multivariable analysis using logistic regression. RESULTS: Of the 898 women, 391 (43.5%) were diagnosed with >or=1 endogenous reproductive tract infection and 157 (17.4%) with >or=1 sexually transmitted infection. Only 863 women had Gram-stained vaginal smears available, out of which 165 (19.1, 95% confidence interval [CI]: 16.3%-22.2%) were found to have BV and 133 (15.4, 95% CI: 12.9%-18.3%) were in the 'intermediate' stage. BV was related to concurrent infections with T. vaginalis (odds ratio [OR]=4.07, 95% CI: 2.45-6.72) and HSV-2 seropositivity (OR=2.22, 95% CI: 1.39-3.53). CONCLUSIONS: In this population, the prevalence of BV at 19% was relatively low. Coinfection with T. vaginalis , however, was common. BV was independently associated with concurrent T. vaginalis infection and partner's alcohol use. Muslim women had reduced odds of BV as compared to non-Muslim women. Further research is needed to understand the role of T. vaginalis infection in the pathogenesis of BV and the sociocultural context surrounding the condition in India.

Novel recruitment strategies to increase participation of women in reproductive health research in India.

In India, care seeking for reproductive health among women is inadequate. This poses a unique challenge to researchers recruiting cohorts for studies in clinic-based settings. The purpose of this paper is to describe the recruitment process used in a prospective cohort study investigating the relationship between bacterial vaginosis and acquisition of HSV-2 among sexually active women in Mysore, India. Participants were initially recruited from an obstetrics/gynaecology outpatient clinic. Results were compared with a 'community supported' enrolment process, which included community preparation and reproductive health education followed by screening of potential participants. During November 2005, 1,054 women were screened in the clinic. Of the total screened, 246 (23%) were eligible and only 78 (7%) enrolled. Between December 2005 and April 2006, investigators adopted a community supported enrolment process. During that period, 1,077 potential participants were screened, 947 were eligible, and 918 (85%) enrolled. Fifty-six (72%) participants recruited from the clinic returned for their first follow-up visit, compared with 795 (97%) participants recruited using the community supported enrolment process. Since obstetrics/gynaecology departments in India are poor places to recruit non-pregnant women of reproductive age, a community supported process yields more eligible potential participants to screen, and results in significantly better study retention.

The clinical and microbiological correlates of premature rupture of membranes.

Prematurity is the cause of 85% of neonatal morbidity and mortality. Premature rupture of the membranes (PROM) is associated with 30-40% of preterm deliveries. A case-control study conducted between July 2002 and 2003 examined the correlates and risk factors for PROM in Mysore, India. WBCs in vaginal fluid, leucocytes in urine, UTI and infection with E. coli, S. aureus, C. albicans and BV were significantly associated with PROM. BV, E. coli and WBCs in vaginal fluid were independent risk factors. Screening and treatment of BV and E. coli infection in pregnancy may reduce the risk of PROM.

Regression of attained milestones in an HIV infected infant.

We report a case of an 18-month-old child with regression of attained developmental milestones as a manifestation of HIV encephalopathy. This is the first such report in Indian literature. Commencing antiretroviral therapy in this child resulted in arrest of further regression of milestones. This alerts pediatricians to be aware that early developmental delay and regression may be a presenting manifestation of HIV infection in a child.

Marriage, monogamy and HIV: a profile of HIV-infected women in south India.

A retrospective study was conducted on 134 HIV-infected females evaluated at an HIV/AIDS centre in south India to characterize their sociodemographics, HIV risk factors and initial clinical presentations. The mean age was 29 years; 81% were housewives; 95% were currently or previously married; 89% reported heterosexual sex as their only HIV risk factor; and 88% reported a history of monogamy. The majority were of reproductive age, thus the potential for vertical transmission of HIV and devastating impacts on families is alarming. Nearly half of these women initially presented asymptomatically implying that partner recruitment can enable early HIV detection. Single partner heterosexual sex with their husband was the only HIV risk factor for the majority of women. HIV prevention and intervention strategies need to focus on married, monogamous Indian women whose self-perception of HIV risk may be low, but whose risk is inextricably linked to the behaviour of their husbands.

Dermatologic manifestations among human immunodeficiency virus patients in south India.

BACKGROUND: Human immunodeficiency virus (HIV) may be associated with a large number of dermatologic manifestations, which may at times constitute the presenting symptoms. These skin lesions are well delineated in the Western literature, but there is a paucity of information from the southern part of the Indian subcontinent. Objective We evaluated 833 persons with HIV to determine the types of dermatologic lesions present. RESULTS: The various lesions observed were oral candidiasis (45.0%), multidermatomal herpes zoster (11.2%), dermatophytosis of the skin (8.0%), herpes genitalis (7.7%), papular pruritic dermatitis (7.7%), staphylococcal infection of the skin (2.9%), oral hairy leukoplakia (2.3%), molluscum contagiosum (1.3%), genital warts (1.2%), and scabies (0.5%). Alopecia, intractable itching, dry skin, Addisonian pigmentation, and Kaposi's sarcoma were also noted. A correlation between the dermatologic manifestations and CD4 cell counts was found. CONCLUSION: Although the pattern of cutaneous lesions was comparable with that from the West, there is a strikingly lower incidence of Kaposi's sarcoma.
