Abstract
BACKGROUND Due to the prolonged life expectancy and increased risk of colorectal cancer (CRC) among patients with human immunodeficiency virus (HIV) infection, the prognosis and pathological features of CRC in HIV-positive patients require examination. AIM To compare the differences in oncological features, surgical safety, and prognosis between patients with and without HIV infection who have CRC at the same tumor stage and site. METHODS In this retrospective study, we collected data from HIV-positive and -negative patients who underwent radical resection for CRC. Using random stratified sampling, 24 HIV-positive and 363 HIV-negative patients with colorectal adenocarcinoma after radical resection were selected. Using propensity score matching, we selected 72 patients, matched 1:2 (HIV-positive:negative = 24:48). Differences in basic characteristics, HIV acquisition, perioperative serological indicators, surgical safety, oncological features, and long-term prognosis were compared between the two groups. RESULTS Fewer patients with HIV infection underwent chemotherapy compared to patients without. HIV-positive patients had fewer preoperative and postoperative leukocytes, fewer preoperative lymphocytes, lower carcinoembryonic antigen levels, more intraoperative blood loss, more metastatic lymph nodes, higher node stage, higher tumor node metastasis stage, shorter overall survival, and shorter progression-free survival compared to patients who were HIV-negative. CONCLUSION Compared with CRC patients who are HIV-negative, patients with HIV infection have more metastatic lymph nodes and worse long-term survival after surgery. Standard treatment options for HIV-positive patients with CRC should be explored.

Abstract
BACKGROUND There is growing consensus that primary health care (PHC) providers have an important role in providing holistic, preventative care for people living with human immunodeficiency virus (PLHIV). In regional Australia, HIV care is primarily delivered through specialist services, thus adequate coordination and communication between specialist and PHC professionals is crucial. This study aimed to explore patient experiences of the coordination of care and health care professional communication for PLHIV in regional Australia. METHODS Semi-structured interviews with PLHIV in a regional area of Australia were conducted in March to April 2022. Interviews were conducted via video conferencing, face-to-face, or via telephone call. Interviews were audio-recorded and manually transcribed. Transcripts were coded inductively and thematic analysis was conducted to explore perspectives on communication and coordination. RESULTS Thirteen participants were interviewed. Most participants were male, aged 50-70, were diagnosed with HIV more than ten years ago, and had been living in regional Australia long-term. Through qualitative analysis, themes emerged in the following areas: (1) Patient perception of care coordination; (2) Patient understanding of modality of communication; (3) Positive attitudes towards communication between healthcare professionals; and (4) Concerns for information sharing between healthcare professionals. Many participants highlighted lack of clarity around care coordination as a key issue in their healthcare, with some citing themselves as the primary care coordinator. Participants identified that coordination and communication between PHC professionals and specialist services are essential in the delivery of their health care, but some were hesitant for this to occur. Hesitancy was entrenched in some patients' distrust of healthcare due to previous experiences of confidentiality breaches and stigma. CONCLUSION This study identifies the need for clarity in coordination between health care professionals to deliver safe and effective HIV care, which may occur through care plans. Patient support for communication between healthcare providers may be strengthened by ensuring trust in the people and systems involved. Eliminating stigma in healthcare as well as building more trustworthy electronic-based communication technologies are essential components to trust-building between PLHIV and healthcare systems.

Abstract
BACKGROUND Studies suggest a lower colorectal cancer (CRC) risk and lower or similar CRC screening among people with HIV (PWH) compared with the general population. We evaluated the incidence of lower endoscopy and average-onset (diagnosed at ≥50) and early-onset (diagnosed at <50) colon cancer by HIV status among Medicaid beneficiares with comparable sociodemographic factors and access to care. METHODS We obtained Medicaid Analytic eXtract (MAX) data from 2001 to 2015 for 14 states. We included 41 727 243 and 42 062 552 unique individuals with at least 7 months of continuous eligibility for the endoscopy and colon cancer analysis, respectively. HIV and colon cancer diagnoses and endoscopy procedures were identified from inpatient and other nondrug claims. We used Cox proportional hazards regression models to assess endoscopy and colon cancer incidence, controlling for age, sex, race/ethnicity, calendar year and state of enrollment, and comorbidities conditions. RESULTS Endoscopy and colon cancer incidence increased with age in both groups. Compared with beneficiaries without HIV, PWH had an increased hazard of endoscopy; this association was strongest among those 18-39 years [hazard ratio: 1.85, 95% confidence interval (95% CI) 1.77-1.92] and attenuated with age. PWH 18-39 years also had increased hazard of early-onset colon cancer (hazard ratio: 1.66, 95% CI:1.05-2.62); this association was attenuated after comorbidity adjustment. Hazard ratios were null among all beneficiaries less than 50 years of age. PWH had a lower hazard of average-onset colon cancer compared with those without HIV (hazard ratio: 0.79, 95% CI: 0.66-0.94). CONCLUSION PWH had a higher hazard of endoscopy, particularly at younger ages. PWH had a lower hazard of average-onset colon cancer. Early-onset colon cancer was higher among the youngest PWH but not associated with HIV overall.

Abstract
HIV-1 associated colorectal cancer (HA-CRC) is one of the most understudied non-AIDS-defining cancers. In this study, we analyzed the proteome of HA-CRC and the paired remote tissues (HA-RT) through data-independent acquisition mass spectrometry (MS). The quantified proteins could differentiate the HA-CRC and HA-RT groups per PCA or cluster analyses. As a background comparison, we reanalyzed the MS data of non-HIV-1 infected CRC (non-HA-CRC) published by CPTAC. According to the GSEA results, we found that HA-CRC and non-HA-CRC shared similarly over-represented KEGG pathways. Hallmark analysis suggested that terms of antiviral response were only significantly enriched in HA-CRC. The network and molecular system analysis centered the crosstalk of IFN-associated antiviral response and cancerous pathways, which was favored by significant up-regulation of ISGylated proteins as detected in the HA-CRC tissues. We further proved that defective HIV-1 reservoir cells as represented by the 8E5 cells could activate the IFN pathway in human macrophages via horizonal transfer of cell-associated HIV-1 RNA (CA-HIV RNA) carried by extracellular vesicles (EVs). In conclusion, HIV-1 reservoir cells secreted and CA-HIV RNA-containing EVs can induce IFN pathway activation in macrophages that contributes to one of the mechanistic explanations of the systems crosstalk between antiviral response and cancerous pathways in HA-CRC.

Abstract
African American men living with HIV are at high risk of colorectal cancer (CRC). Screening to detect CRC is associated with a reduced risk of CRC mortality. However, little is known about CRC screening predictors in this population. This study examined the relation of self-efficacy, a potential mediator of screening that interventions could target, to CRC screening. It also investigated several variables that might identify subpopulations of African American men non-adherent to CRC screening recommendations. We report a secondary analysis on baseline data from a randomized controlled trial of a health promotion intervention for African American men living with HIV. Before their intervention, they completed measures of CRC screening, self-efficacy, marital status, age, education, and adherence to physical activity guidelines and were assessed for obesity. A total of 270 African American men aged 45 to 88 (Mean = 55.07; SD = 6.46) living with HIV participated. About 30% reported CRC screening in the past six months. Multiple logistic regression revealed greater CRC screening self-efficacy and meeting physical activity guidelines were associated with receiving CRC screening. Obese men and men reporting higher education were less likely to report screening. Age and marital status were unrelated to screening. The results of this study suggest CRC screening rates may be low among African American men living with HIV, and interventions targeting self-efficacy may improve their screening uptake. Moreover, public-health efforts to increase screening should prioritize interventions with subpopulations of African American men living with HIV who are physically inactive and obese.

Abstract
The usage of combination antiretroviral therapy in people with HIV (PWH) has incited profound improvement in morbidity and mortality. Yet, PWH may not experience full restoration of immune function which can manifest with non-AIDS comorbidities that frequently associate with residual inflammation and can imperil quality of life or longevity. In this review, we discuss the pathogenesis underlying chronic inflammation and residual immune dysfunction in PWH, as well as potential therapeutic interventions to ameliorate them and prevent incidence or progression of non-AIDS comorbidities. Current evidence advocates that early diagnosis and prompt initiation of therapy at high CD4 counts may represent the best available approach for an improved immune recovery in PWH.

Abstract
Background: Women living with HIV in Canada experience barriers to comprehensive HIV care. We sought to describe care gaps across a typology of care. Methods: We analyzed baseline data from the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS). A typology of care was characterized by primary HIV physician and care setting. Quality-of-care indicators included the following: Pap test, Pap test discussions, reproductive goal discussions, breast cancer screening, antiretroviral therapy (ART) use, adherence, HIV viral load, and viral load discussions. We defined comprehensive care with three indicators: Pap test, viral load, and either reproductive goal discussions over last 3 years or breast cancer screening, as indicated. Multivariable logistic regression analyses measured associations between care types and quality-of-care indicators. Results: Among women living with HIV accessing HIV care, 56.4% (657/1,164) experienced at least one gap in comprehensive care, most commonly reproductive goal discussions. Women accessed care from three types of care: (1) physicians (specialist and family physicians) in HIV clinics (71.6%); (2) specialists in non-HIV clinics (17.6%); and (3) family physicians in non-HIV clinics (10.8%), with 55.5%, 63.9%, and 50.8% gaps in comprehensive care, respectively. Type 3 care had double the odds of not being on ART: adjusted odds ratio (AOR 2.09, 95% confidence interval [CI] 1.16-3.75), while Type 2 care had higher odds of not having discussed the importance of Pap tests (AOR 1.48, 95% CI 1.00-2.21). Discussion: Women continue to experience gaps in care, across types of care, indicating the need to evaluate and strengthen women-centered models of care.

Abstract
BACKGROUND As people with HIV (PWH) live longer, age-appropriate colorectal cancer (CRC) screening is increasingly important. Limited data exist on CRC screening and outcomes comparing PWH and persons without HIV. SETTING Large integrated health care system. METHODS This study included PWH and demographically matched persons without HIV who were aged 50-75 years during 2005-2016 and had no previous CRC screening. We evaluated time to first CRC screening (fecal test, sigmoidoscopy, or colonoscopy). We also assessed detection of adenoma and CRC with sigmoidoscopy or colonoscopy by HIV status, accounting for CRC risk factors including sex, age, race/ethnicity, number of outpatient visits, smoking, body mass index, type-2 diabetes, and inflammatory bowel disease. Among PWH, we evaluated whether CD4 count (<200/200-499/≥500 cells/µL) was associated with adenoma and CRC. RESULTS Among 3177 PWH and 29,219 persons without HIV, PWH were more likely to be screened (85.6% vs. 79.1% within 5 years, P < 0.001). Among those with sigmoidoscopy or colonoscopy, adenoma was detected in 161 (19.6%) PWH and 1498 (22.6%) persons without HIV, and CRC was detected in 4 (0.5%) PWH and 69 (1.0%) persons without HIV. In adjusted analyses, we found no difference in prevalence of either adenoma or CRC by HIV status (adjusted prevalence ratio = 0.97, 95% confidence interval: 0.83 to 1.12). Lower CD4 count did not increase likelihood of adenoma or CRC. CONCLUSIONS Within an integrated health care system with an organized CRC screening program, we found no disparities in CRC screening uptake or outcomes among people with and without HIV, and CD4 count did not influence CRC risk among PWH.

Abstract
Background Although people living with HIV or AIDS (PLWHA) are at higher risk for many cancers, breast, prostate, and colorectal cancer rates are lower in this patient population. Because these tumors are often screen-detected, these inverse associations could be driven by HIV-related differences in utilization of cancer screening. Methods We ascertained incident breast, prostate, and colorectal cancer in PLWHA using data from the HIV/AIDS Cancer Match Study (1996-2012). Comparisons with general population cancer rates were made using standardized incidence ratios (SIRs), overall and stratified by tumor stage/size, breast cancer estrogen receptor status, and colorectal site. We also examined the potential effect of study design and unmeasured confounding on inverse standardized incidence ratios. Results Compared with the general population, PLWHA had lower rates of invasive breast (SIR = 0.63, 95% confidence interval [CI] = 0.58 to 0.68), prostate (SIR = 0.48, 95% CI = 0.46 to 0.51), proximal colon (SIR = 0.67, 95% CI = 0.59 to 0.75), distal colon (SIR = 0.51, 95% CI = 0.43 to 0.59), and rectal cancers (SIR = 0.69, 95% CI = 0.61 to 0.77). Reduced risk persisted across tumor stage/size for prostate and colorectal cancers. Although distant-stage breast cancer rates were not reduced (SIR = 0.94, 95% CI = 0.73 to 1.20), HIV-infected women had lower rates of large (>5 cm) breast tumors (SIR = 0.65, 95% CI = 0.50 to 0.83). The magnitude of these inverse standardized incidence ratios could not plausibly be attributed to case underascertainment, out-migration, or unmeasured confounding. Conclusions Breast, prostate, and colorectal cancer rates are markedly lower among PLWHA, including rates of distant-stage/large tumors that are not generally screen-detected. This set of inverse HIV-cancer associations is therefore unlikely to be due primarily to differential screening and may instead represent biological relationships requiring future investigation.

Abstract
With the advent of continuous antiretroviral therapy, HIV has become a complex chronic, rather than acute, condition. The Chronic Care Model (CCM) provides an integrated approach to the delivery of care for people with chronic conditions that could therefore be applied to the delivery of care for people living with HIV. Our objective was to assess the alignment of HIV care settings with the CCM. We conducted a mixed methods study to explore structures, organization and care processes of Canadian HIV care settings. The quantitative results of phase one are published elsewhere. For phase two, we conducted semi-structured interviews with key informants from 12 HIV care settings across Canada. Irrespective of composition of the care setting or its location, HIV care in Canada is well aligned with several components of the CCM, most prominently in the areas of linkage to community resources and delivery system design with inter-professional team-based care. We propose the need for improvements in the availability of electronic clinical information systems and self-management support services to support better care delivery and health outcomes among people living with HIV in Canada.

Abstract
Background and Aims The incidence and mortality of colorectal cancer is persistently highest in Black/African-Americans in the United States. While access to care, barriers to screening, and poverty might explain these findings, there is increased interest in examining biological factors that impact the colonic environment. Our group is examining biologic factors that contribute to disparities in development of adenomas prospectively. In preparation for this and to characterize a potential patient population, we conducted a retrospective review of initial screening colonoscopies in a cohort of patients. Methods A retrospective review was performed on initial average risk screening colonoscopies on patients (age 45-75 years) during 2012 at three institutions. Descriptive statistics and multivariable logistic regression models were used to examine the relationship between potential risk factors and the detection of adenomas. Results Of the 2225 initial screening colonoscopies 1495 (67.2%) were performed on Black/African-Americans and 566 (25.4%) on Caucasians. Multivariable logistic regression revealed that older age, male sex, current smoking and teaching gastroenterologists were associated with higher detection of adenomas and these were less prevalent among Black/African-Americas except for age. Neither race, ethnicity, BMI, diabetes mellitus, HIV nor insurance were associated with adenoma detection. Conclusion In this sample, there was no association between race and adenoma detection. While this may be due to a lower prevalence of risk factors for adenomas in this sample, our findings were confounded by a lower detection rate by consultant gastroenterologists at one institution. The study allowed us to rectify the problem and characterize patients for future trials.

Abstract
BACKGROUND People with HIV (PWHIV) have improved survival because of the advent of antiretroviral therapy. Consequently, PWHIV experience higher rates of non-acquired immunodeficiency syndrome-defining malignancies (NADMs). Previous studies have demonstrated worsened cancer-specific survival in PWHIV, partly because of advanced cancer stage at diagnosis. The objective of the current systematic review was to evaluate screening disparities for NADMs among PWHIV. METHODS The PubMed, Cochrane, EMBASE, and ClinicalTrials.gov databases were searched from January 1, 1996 through April 10, 2018 to identify studies related to screening disparities for NADMs among PWHIV. Eligibility criteria included any study performed in a high-income country that compared screening for NADMs by HIV status. After title/abstract screening and full-text review, articles that met eligibility criteria were analyzed. RESULTS Of 613 unique articles identified through the search, 9 studies were analyzed. Three studies addressed breast cancer screening, 4 addressed colorectal cancer screening, and 2 addressed prostate cancer screening. Five of the reviewed studies demonstrated that PWHIV were less likely to receive indicated cancer screenings compared with the general population, whereas 3 indicated that screening proportions were higher among PWHIV, and 1 demonstrated that screening proportions were comparable. In most of the studies, PWHIV who had regular access to health care were more likely to undergo cancer screening. CONCLUSIONS The available evidence does not uniformly confirm that PWHIV are less likely to receive cancer screening. Social determinants of health (insurance status, access to health care, education, income level) were associated with the receipt of appropriate cancer screening, suggesting that these barriers need to be addressed to improve cancer screening in PWHIV.

Abstract
This study examined access to care and satisfaction among health center patients with chronic conditions. Data for this study were obtained from the 2009 Health Center Patient Survey. Dependent variables of interest included 5 measures of access to and satisfaction with care, whereas the main independent variable was number of chronic conditions. Results of bivariate analysis and multiple logistic regressions showed that patients with chronic conditions had significantly higher odds of reporting access barriers than those without chronic conditions. Our results suggested that additional efforts and resources are necessary to address the needs of health center patients with chronic conditions.

Abstract
Models of care for people living with HIV (PLWH) have varied over time due to long term survival, development of HIV-associated non-AIDS conditions, and HIV specific primary care guidelines that differ from those of the general population. The objectives of this study are to assess how often infectious disease (ID) physicians provide primary care for PLWH, assess their practice patterns and barriers in the provision of primary care. We used a 6-item survey electronically distributed to ID physician members of Emerging Infections Network (EIN). Of the 1248 active EIN members, 644 (52%) responded to the survey. Among the 644 respondents, 431 (67%) treated PLWH. Of these 431 responders, 326 (75%) acted as their primary care physicians. Responders who reported always/mostly performing a screening assessment as recommended per guidelines were: (1) Screening specific to HIV (tuberculosis 95%, genital chlamydia/gonorrhoea 77%, hepatitis C 67%, extra genital chlamydia/gonorrhoea 47%, baseline anal PAP smear for women 36% and men 34%); (2) Primary care related screening (fasting lipids 95%, colonoscopy 95%, mammogram 90%, cervical PAP smears 88%, depression 57%, osteoporosis in postmenopausal women 55% and men >50 yrs 33%). Respondents who worked in university hospitals, had <5 years of ID experience, and those who cared for more PLWH were most likely to provide primary care to all or most of their patients. Common barriers reported include: refusal by patient (72%), non-adherence to HIV medications (43%), other health priorities (44%), time constraints during clinic visit (43%) and financial/insurance limitations (40%). Most ID physicians act as primary care providers for their HIV infected patients especially if they are recent ID graduates and work in university hospitals. Current screening rates are suboptimal. Interventions to increase screening practices and to decrease barriers are urgently needed to address the needs of the aging HIV population in the United States.

Abstract
BACKGROUND As people with HIV live longer, the numbers of colorectal cancer cases are expected to increase. We sought to compare the colorectal cancer incidence and cause-specific mortality among people living with and without HIV. DESIGN Systematic review and meta-analysis. METHODS We searched 5 electronic databases up to June 28, 2016, for primary studies reporting standardized incidence ratios (SIRs), standardized mortality ratios (SMRs)/hazard ratios or data sufficient for estimating these summary measures. We performed a random effects pooled analysis to estimate SIR and SMR of colorectal cancer in HIV. RESULTS Of 8110 articles, we included 27 studies from North America (n = 18), Europe (n = 7), the Pacific region (n = 4), and South America (n = 1). Overall, 1660 cases of colorectal cancer and colon cancer (excluding rectal cancer) occurred among 1,696,070 persons with HIV. In pooled analysis, we found no summary risk of malignancy among those with HIV relative to an uninfected population (SIR 1.00; 95% confidence interval 0.82 to 1.22; I = 89.2%). Colorectal cancer-specific mortality was higher among people with HIV but did not reach statistical significance (SMR 2.09; 95% confidence interval: 1.00 to 4.40; I = 85.0%). CONCLUSIONS Rates of colorectal cancer are similar between people with and without HIV. Existing screening guidelines are likely adequate for people with HIV.

Abstract
Importance The Human Immunodeficiency Virus (HIV) epidemic has evolved, with an increasing non-communicable disease (NCD) burden emerging and need for long-term management, yet there are limited data to help delineate the optimal care model to screen for NCDs for this patient population. Objective The primary aim was to compare rates of NCD preventive screening in persons living with HIV/AIDS (PLWHA) by type of HIV care model, focusing on metabolic/cardiovascular disease (CVD) and cancer screening. We hypothesized that primary care models that included generalists would have higher preventive screening rates. Design Prospective observational cohort study. Setting Partners HealthCare System (PHS) encompassing Brigham & Women’s Hospital, Massachusetts General Hospital, and affiliated community health centers. Participants PLWHA age >18 engaged in active primary care at PHS. Exposure HIV care model categorized as infectious disease (ID) providers only, generalist providers only, or ID plus generalist providers. Main Outcome(s) and Measures(s) Odds of screening for metabolic/CVD outcomes including hypertension (HTN), obesity, hyperlipidemia (HL), and diabetes (DM) and cancer including colorectal cancer (CRC), cervical cancer, and breast cancer. Results In a cohort of 1565 PLWHA, distribution by HIV care model was 875 ID (56%), 90 generalists (6%), and 600 ID plus generalists (38%). Patients in the generalist group had lower odds of viral suppression but similar CD4 counts and ART exposure as compared with ID and ID plus generalist groups. In analyses adjusting for sociodemographic and clinical covariates and clustering within provider, there were no significant differences in metabolic/CVD or cancer screening rates among the three HIV care models. Conclusions There were no notable differences in metabolic/CVD or cancer screening rates by HIV care model after adjusting for sociodemographic and clinical factors. These findings suggest that HIV patients receive similar preventive health care for NCDs independent of HIV care model.

Abstract
INTRODUCTION The introduction of Highly Active Antiretroviral Therapy (HAART) into clinical practice has dramatically changed the outcome of HIV-infected patients by prolonging their survival. The increase in life expectancy has led to an increased risk of non-AIDS-related mortality and morbidity, including cardiovascular diseases, neurocognitive diseases, neuroendocrine dysfunctions and cancer. Areas covered: The GICAT (Italian Cooperation Group on AIDS and Tumors) has demonstrated that patients who receive a multidisciplinary approach with the combination of anticancer agents (AC) and HAART can achieve better responses and survival rates than patients who receive AC alone. The first obstacle for the oncologist to plan treatment for cancer HIV-patients is the preliminary evaluation of drug-drug interactions between AC and HAART. Recent progress in pharmacogenomics could provide a new approach for personalized treatments. The rationale of this review is to summarize the existing data on the impact of HAART on the clinical management of cancer patients with HIV/AIDS and DDIs between antiretrovirals and AC. In addition, to maximize the efficacy of both concomitant therapy and to minimize the risk of DDIs, a currently useful list of pharmacogenomic markers of key metabolic enzymes is provided. Expert opinion: In this scenario, the importance of cooperation between oncologists and other health specialists (i.e., infectivologists, pharmacists, genetics and lab specialists) must not be underestimated in the management of these patients with the aim of planning an individual treatment strategy.

Abstract
The role of HIV specialists in providing primary care to persons living with HIV/AIDS is evolving, given their increased incidence of comorbidities. Multivariate logit analysis compared compliance with sentinel preventive screening tests and interventions among publicly insured Californians with and without access to HIV specialists in 2010. Quality-of-care indicators [visit frequency, CD4 and viral load (VL) assessments, influenza vaccine, tuberculosis (TB) testing, lipid profile, glucose blood test, and Pap smears for women] were related to patient characteristics and provider HIV caseload. There were 9377 adult Medicare enrollees (71% also had Medicaid coverage) and 2076 enrollees with only Medicaid coverage. Adjusted for patient characteristics, patients seeing providers with greater HIV caseloads (>50 HIV patients) were more likely to meet visit frequency guidelines in both Medicare [98%; confidence interval (CI 97.5-98.2) and Medicaid (97%; CI 96.2-98.0), compared to 60% (CI 57.1-62.3) and 45% (CI 38.3-50.4), respectively, seeing providers without large HIV caseloads (p < 0.001). Patients seeing providers with larger caseloads were significantly more likely to have CD4 (p < 0.001), VL (p < 0.001), and TB testing (p < 0.05). A larger percentage of patients seeing large-volume Medicare providers received influenza vaccinations. Provider caseload was unrelated to lipid or glucose assessments or Pap Smears for women. Patients with access to large-volume providers were more likely to meet clinical guidelines for visits, CD4, VL, tuberculosis testing, and influenza vaccinations, and were not less likely to receive primary preventive care. Substantial insufficiencies remain in both monitoring to assess viral suppression and in preventive care.

Abstract
BACKGROUND HIV has become a chronic disease, which may render this population more prone to developing the colorectal pathologies that typically affect older Americans. METHODS A retrospective review of the Nationwide Inpatient Sample was performed to identify patients who underwent colon and rectal surgery from 2001 to 2010. Multivariate analysis was used to evaluate outcomes among the general population, patients with HIV, and patients with AIDS. RESULTS Hospital admissions for colon and rectal procedures of patients with HIV/AIDS grew at a faster rate than all-cause admissions of patients with HIV/AIDS, with mean yearly increases of 17.8 and 2.1 %, respectively (p < 0.05). Patients with HIV/AIDS undergoing colon and rectal operations for cancer, polyps, diverticular disease, and Clostridium difficile were younger than the general population (51 vs. 65 years; p < 0.01). AIDS was independently associated with increased odds of mortality (OR 2.11; 95 % CI 1.24, 3.61), wound complications (OR 1.53; 95 % CI 1.09, 2.17), and pneumonia (OR 2.02; 95 % CI 1.33, 3.08). Risk-adjusted outcomes of colorectal surgery in patients with HIV did not differ significantly from the general population. CONCLUSION Postoperative outcomes in patients with HIV are similar to the general population, while patients with AIDS have a higher risk of mortality and certain complications.

Abstract
PURPOSE Greater physician experience managing human immunodeficiency virus (HIV) infection has been associated with better HIV-specific outcomes. The objective of this study was to evaluate whether the HIV experience of a family physician modifies the association between the model of care delivery and the quality of care for people living with HIV. METHODS We retrospectively analyzed data from a population-based observational study conducted between April 1, 2009, and March 31, 2012. A total of 13,417 patients with HIV in Ontario were stratified into 5 possible patterns or models of care. We used multivariable hierarchical logistic regression analyses, adjusted for patient characteristics and pairwise comparisons, to evaluate the modification of the association between care model and indicators of quality of care (receipt of antiretroviral therapy, cancer screening, and health care use) by level of physician HIV experience (≤5, 6-49, ≥50 patients during study period). RESULTS The majority of HIV-positive patients (52.8%) saw family physicians exclusively for their care. Among these patients, receipt of antiretroviral therapy was significantly lower for those receiving care from family physicians with 5 or fewer patients and 6-49 patients compared with those with 50 or more patients (mean levels of adherence [95% CIs] were 0.34 [0.30-0.39] and 0.40 [0.34-0.45], respectively, vs 0.77 [0.74-0.80]). Patients' receipt of cancer screenings and health care use were unrelated to family physician HIV experience. CONCLUSIONS Family physician HIV experience was strongly associated with receipt of antiretroviral therapy by HIV-positive patients, especially among those seeing only family physicians for their care. Future work must determine the best models for integrating and delivering comprehensive HIV care among diverse populations and settings.

Abstract
HIV-positive patients have lower colon cancer screening rates and are at increased risk for colon adenocarcinoma. We tested a transdisciplinary prevention model to increase provider and patient adherence to screening colonoscopy. Of 1,339 HIV-positive patients with scheduled clinic appointments during the period September to November 2009, we identified 400 records of eligible patients ≥50 years and retrospectively reviewed for screening colonoscopy referral; if never referred, flagged for referral at next visit. Providers referred 43.5% (174/400) patients and 36.2% (63/174) kept appointment. Within 6 months before the study, 337 patients attended clinic and providers referred 18%. Note that 211/226 patients with flagged records attended clinic at least once during the study 6-month period and providers referred (43.6%). The referral rate for flagged records was significantly different from that for the prior 6 months (p < 0.0001). A randomized trial compared the efficacy of patient decision support versus usual care on screening adherence. Among patients randomized to intervention 17 (51.5%) compared to usual care only 16 (48.5%), intervention group showed significant adherence of 70.6% (12/17) versus 29.4% (5/16), (p = 0.024). In addition, intervention patients had good bowel preparation of 76.9% (10/13) versus usual care 23.1% (3/13), (p = 0.05). This transdisciplinary intervention model significantly increased provider and patient screening colonoscopy behavior.

Abstract
OBJECTIVES Physician specialty is often positively associated with disease-specific outcomes and negatively associated with primary care outcomes for people with chronic conditions. People with HIV have increasing comorbidity arising from antiretroviral therapy (ART) related longevity, making HIV a useful condition to examine shared care models. We used a previously described, theoretically developed shared care framework to assess the impact of care delivery on the quality of care provided. DESIGN Retrospective population-based observational study from 1 April 2009 to 31 March 2012. PARTICIPANTS 13 480 patients with HIV and receiving publicly funded healthcare in Ontario were assigned to one of five patterns of care. OUTCOME MEASURES Cancer screening, ART prescribing and healthcare utilisation across models using adjusted multivariable hierarchical logistic regression analyses. RESULTS Models in which patients had an assigned family physician had higher odds of cancer screening than those in exclusively specialist care (colorectal cancer screening, exclusively primary care adjusted OR (AOR)=3.12, 95% CI (1.90 to 5.13), family physician-dominant co-management AOR=3.39, 95% CI (1.94 to 5.93), specialist-dominant co-management AOR=2.01, 95% CI (1.23 to 3.26)). The odds of having one emergency department visit did not differ among models, although the odds of hospitalisation and HIV-specific hospitalisation were lower among patients who saw exclusively family physicians (AOR=0.23, 95% CI (0.14 to 0.35) and AOR=0.15, 95% CI (0.12 to 0.21)). The odds of antiretroviral prescriptions were lower among models in which patients' HIV care was provided predominantly by family physicians (exclusively primary care AOR=0.15, 95% CI (0.12 to 0.21), family physician-dominant co-management AOR=0.45, 95% CI (0.32 to 0.64)). CONCLUSIONS How care is provided had a potentially important influence on the quality of care delivered. Our key limitation is potential confounding due to the absence of HIV stage measures.

Abstract
With improved survival and aging, more persons living with HIV/AIDS (PLWHA) are at risk for colorectal cancer (CRC). This retrospective longitudinal study evaluated patient characteristics associated with CRC screening in our HIV cohort. Patients were followed beginning at age 50 years during a study period from January 1, 2003 to December 31, 2010 (n=265). During a median follow-up time of 1.7 years, only 30% of patients underwent CRC screening. The majority of screened patients received endoscopic screening (colonoscopy, 86%; sigmoidoscopy, 8%); among these patients, results were available for 68/75, and adenomatous polyps were found in 13%. No cases of CRC were reported. Among unscreened patients, only 23% had an external primary care provider, indicating an HIV provider was the expected source for CRC screening referral in the majority. Patients with time-varying suppressed HIV viral load were more likely to receive screening (HRadjusted=1.74; 95% CI: 1.05-2.87), independent of CD4 count. Our findings suggest HIV providers are more likely to address non-HIV-related healthcare maintenance when HIV is controlled. In addition, a significant number of neoplastic lesions are likely being missed in PLWHA who have not been screened for CRC. Provision of evidence-based preventive care in addition to HIV care is required for the aging population of PLWHA.

Health administrative data can be used to define a shared care typology for people with HIV. J Clin Epidemiol 2015; 68:1301-11.

Abstract
OBJECTIVES Building on an existing theoretical shared primary care/specialist care framework to (1) develop a unique typology of care for people living with human immunodeficiency virus (HIV) in Ontario, (2) assess sensitivity of the typology by varying typology definitions, and (3) describe characteristics of typology categories. STUDY DESIGN AND SETTING Retrospective population-based observational study from April 1, 2009, to March 31, 2012. A total of 13,480 eligible patients with HIV and receiving publicly funded health care in Ontario. We derived a typology of care by linking patients to usual family physicians and to HIV specialists with five possible patterns of care. Patient and physician characteristics and outpatient visits for HIV-related and non-HIV-related care were used to assess the robustness and characteristics of the typology. RESULTS Five possible patterns of care were described as low engagement (8.6%), exclusively primary care (52.7%), family physician-dominated comanagement (10.0%), specialist-dominated comanagement (30.5%), and exclusively specialist care (5.2%). Sensitivity analyses demonstrated robustness of typology assignments. Visit patterns varied in ways that conform to typology assignments. CONCLUSION We anticipate this typology can be used to assess the impact of care patterns on the quality of primary care for people living with HIV.

Abstract
BACKGROUND People with HIV are living longer and their care has shifted towards the prevention and management of comorbidities. However, little is known about who is providing their care. Our objective was to characterize the provision of HIV care in Ontario by physician specialty. METHODS We conducted a retrospective population-based observational study using linked administrative databases in Ontario, Canada, a single payer health care system. All Ontarians with HIV were identified using a validated case ascertainment algorithm. We examined office-based health care visits for this cohort between April 1, 2009 and March 31, 2012. Physician characteristics were compared between specialty groups. We stratified the frequency and distribution of physician care into three categories: (a) care by physician specialty (family physicians, internal medicine specialists, infectious disease specialists, and other specialists), (b) care based on physician caseload (low, medium or high categorized as ≤5, 6-49 or ≥50 HIV patients per physician), and (c) care that is related to HIV versus unrelated to HIV. RESULTS Family physicians were older, graduated earlier, were more often female, and were the only group practicing in rural settings. Unlike other specialists, most family physicians (76.8%) had low-volume caseloads. There were 406,411 outpatient visits made by individuals with HIV; one-third were for HIV care. Family physicians provided the majority of care (53.6% of all visits and 53.9% of HIV visits). Internal medicine specialists provided 4.9% of all visits and 9.6% of HIV visits. Infectious disease specialists provided 12.5% of all visits and 32.7% of HIV visits. Other specialties provided 29.0% of visits; most of these (33.0%) were to psychiatrists. CONCLUSIONS The distribution of visits to physicians caring for HIV patients reveals different patterns of health care delivery by specialty and HIV caseload. Further research should delineate how specialties share care for this population and how different patterns relate to quality of care.

Abstract
Background Because of the increased life-expectancy of persons with HIV, the need for age-appropriate colorectal cancer screening among these patients will increase. We examined rates of colorectal cancer screening among HIV-infected men aged 50 to 65 years. Methods We used Ontario’s administrative databases to identify all men between the ages of 50 and 65 years who were alive on April 1, 2007, and identified HIV-infected men using a validated case-finding algorithm. We excluded men with a history of colorectal cancer, anal cancer, inflammatory bowel disease and any colorectal investigation in the preceding five-years, and used multivariable regression to compare rates of colorectal cancer screening between men with and without HIV during five years of follow-up. Results We identified 743,801 men between the ages of 50 and 65 years, of whom 1,432 (0.19%) were HIV-infected. The proportions of men with and without HIV who underwent any screening during the 5-year follow up period were 49.1% (95% CI 46.5% to 51.7%) and 41.4% (95% CI 41.3% to 41.5%), respectively. Compared with HIV-negative men, men with HIV had lower rates of fecal occult blood testing [adjusted rate ratio (aRR) 0.74; 95% confidence interval (CI) 0.63 to 0.87] and barium-enema radiography (aRR 0.66; 95% CI 0.39 to 1.12), but higher rates of colonoscopy (aRR 1.24; 95% CI 1.13 to 1.37), flexible sigmoidoscopy (aRR 1.72; 95% CI 1.28 to 2.30) and rigid sigmoidoscopy (aRR 2.98; 95% CI 2.26 to 3.93). Conclusion As with the general population of men aged 50 to 65 years, less than half of the population of men with HIV received colorectal cancer screening. Strategies are required to improve uptake of this intervention.

Abstract
BACKGROUND As people diagnosed with HIV and receiving combination antiretroviral therapy are now living longer, they are likely to acquire chronic conditions related to normal ageing and the effects of HIV and its treatment. Comordidities for people with HIV have not previously been described from a representative population perspective. METHODS We used linked health administrative data from Ontario, Canada. We applied a validated algorithm to identify people with HIV among all residents aged 18 years or older between April 1, 1992 and March 31, 2009. We randomly selected 5 Ontario adults who were not identified with HIV for each person with HIV for comparison. Previously validated case definitions were used to identify persons with mental health disorders and any of the following physical chronic diseases: diabetes, congestive heart failure, acute myocardial infarction, stroke, hypertension, asthma, chronic obstructive lung disease, peripheral vascular disease and end-stage renal failure. We examined multimorbidity prevalence as the presence of at least two physical chronic conditions, or as combined physical-mental health multimorbidity. Direct age-sex standardized rates were calculated for both cohorts for comparison. RESULTS 34.4% (95% confidence interval (CI) 33.6% to 35.2%) of people with HIV had at least one other physical condition. Prevalence was especially high for mental health conditions (38.6%), hypertension (14.9%) and asthma (12.7%). After accounting for age and sex differences, people with HIV had significantly higher prevalence of all chronic conditions except myocardial infarction and hypertension, as well as substantially higher multimorbidity (prevalence ratio 1.30, 95% CI 1.18 to 1.44) and combined physical-mental health multimorbidity (1.79, 95% CI 1.65 to 1.94). Prevalence of multimorbidity among people with HIV increased with age. The difference in prevalence of multimorbidity between the two cohorts was more pronounced among women. CONCLUSION People living with HIV in Ontario, especially women, had higher prevalence of comorbidity and multimorbidity than the general population. Quantifying this morbidity at the population level can help inform healthcare delivery requirements for this complex population.

Abstract
Non-AIDS defining malignancies, particularly colorectal cancer (CRC), may be more prevalent among persons living with HIV (PLWH). Further, PLWH may be less likely to receive CRC screening (CRCS). We studied the epidemiology of CRC and CRCS patterns in PLWH and HIV-uninfected persons in a large US Medicaid population. We performed a matched cohort study examining CRC incidence in 2006 and CRCS between 1999 and 2007. Study participants were continuously enrolled in the Medicaid programs of California, Florida, New York, Ohio, and Pennsylvania. All PLWH enrollees were matched to five randomly sampled HIV-uninfected enrollees on 5-year age group, gender, and state. Adjusted odds ratios (AORs) for incident CRC (adjusted for comorbidity index) and the presence of CRCS (adjusted for comorbidity index and years in the data-set) among PLWH compared to HIV-uninfected enrollees were calculated. PLWH were not more likely to be diagnosed with CRC after adjusting for comorbidity index (unadjusted OR: 1.73, 95% confidence interval [CI]: 1.37-2.19; AOR 1.29; 95% CI: 0.98-1.70). While CRCS rates were low overall, PLWH were more likely to have received CRCS in unadjusted analyses (35.8% vs. 33.7%; OR 1.10, 95% CI: 1.07-1.13). This relationship was reversed after adjusting for comorbidity index and years in the data-set (AOR: 0.80, 95% CI: 0.77-0.83). Limitations of the study include a focus on the Medicaid population, an inability to detect fecal occult blood tests (FOBT), and having half of patients between 50 and 55 years of age. In conclusion, PLWH were not more likely to be diagnosed with CRC, but in adjusted analyses, were less likely to have received CRCS. As we showed a low rate of CRCS overall in this Medicaid population, researchers, clinicians, and policy-makers should improve access to and uptake of CRCS among all Medicaid patients, and particularly among PLWH.

Abstract
In the highly active antiretroviral therapy (HAART) era, the incidence of non-AIDS-defining cancers (NADC) has increased and contributes to a growing proportion of mortality in the aging HIV-infected population. The underlying pathogenic mechanisms of increased cancer risk are incompletely understood. Potential contributors include oncogenic effects of the HIV virus, immunosuppression, chronic inflammation and immune activation, exposure to HAART, higher rates of oncogenic viral coinfections and traditional cancer risk factors. HIV-infected patients often present with NADC at younger ages with more aggressive or advanced stage disease. However, when standard cancer therapy is given, treatment outcomes appear similar to the non-HIV population. These facts highlight the importance of clinicians' maintaining a high index of suspicion, performing age-appropriate screening, and optimizing cancer therapy. Development of novel strategies for screening, prevention, and treatment of NADC will be required to reverse these epidemiologic trends and improve the survival of HIV-infected patients.

Abstract
AIM: To evaluate if human immunodeficiency virus (HIV) population is getting adequate screening for colon cancer in the highly active anti-retroviral treatment (HAART) era with improved longevity, and the prevalence of polyps and adenomas in this population, when compared with the general population.
METHODS: We conducted retrospective chart review of average-risk HIV population for colon cancer attending our infectious disease clinic. Individuals who underwent diagnostic colonoscopy were excluded. We extracted various demographic, HIV disease-specific and colonoscopy data including histo-pathological reports in the last 10 years. Total population was divided into a study group, who underwent screening colonoscopy and a control group who did not. We analyzed data using standard statistical methods and software.
RESULTS: We found that 25% of average-risk HIV-infected population was screened for colon cancer using colonoscopy. There was no difference in gender and ethnic distribution between the groups. We found wider distribution of age (50-84 years with mean 56 years) in the control group when compared to (50-73 years with mean 58 years) the study group. However, there were 89% of subjects with well-controlled HIV disease measured by HIV RNA copies of < 75 in the study group when compared with 70% in the control group (P < 0.0001). We noticed polyp detection rate of 55% and adenoma detection rate of 32% in HIV population.
CONCLUSION: It is unclear whether HIV or HAART medications play a role in increased prevalence of adenomas. We suggest that when estimating the risk for colonic neoplasms, HIV population should be considered as a high-risk group and screened accordingly.

Abstract
BACKGROUND As HIV positive patients live longer, they become susceptible to the development of non-AIDS defining malignancies. Little is known about routine cancer screening practices in that population and the factors associated with cancer screening. OBJECTIVE Evaluate 1) the proportion of patients with HIV who had any type of colorectal cancer (CRC) screening and 2) whether having a primary care physician (PCP) or seeking care in an integrated care practice is associated with higher CRC screening. DESIGN A cross-sectional chart abstraction study of patients with HIV enrolled in the Philadelphia Medical Monitoring Project (MMP). PARTICIPANTS MMP participants age 50 and older. MAIN MEASURES CRC screening defined as having a documented colonoscopy, sigmoidoscopy, barium enema, or fecal occult blood test after the age of 50. KEY RESULTS Out of 123 chart abstractions performed, 115 had a complete clinical record from MMP. The majority of the population was male (71.3%), Black/Hispanic (73.8%) and between the age of 50 and 59 (71.3%). 45.2% of patients did not have a PCP. The overall proportion of patients who received CRC screening was 46.9%. Having a documented PCP was the only factor strongly associated with CRC screening. Rates of screening were 66.7% among those with a PCP versus 28.5% among those without a PCP (χ(2) p < 0.001). After adjusting for race, socioeconomic status, substance and alcohol abuse, the odds of getting CRC screening in those with a PCP was 4.59 (95% CI 2.01-10.48, p < 0.001). The type of practice where patients were enrolled into care was not associated with CRC screening. CONCLUSIONS Having a PCP significantly increases the likelihood of receiving CRC screening in patients with HIV. Competency in addressing primary care needs in HIV clinics will only become more important as patients with HIV age.

Abstract
Since the advent of HAART, patients with HIV infection have seen a significant improvement in their morbidity, mortality, and life expectancy. The incidence of AIDS-defining illnesses, including AIDS-defining malignancies, has been on the decline. However, deaths due to non-AIDS-defining illnesses have been on the rise. These so-called non-AIDS-defining cancers (NADCs) include cancers of the lung, liver, kidney, anus, head and neck, and skin, as well as Hodgkin's lymphoma. It is poorly understood why this higher rate of NADCs is occurring. The key challenge facing oncologists is how to administer chemotherapy effectively and safely to patients on antiretroviral therapy. The challenge to clinicians caring for HIV-infected patients is to develop and implement effective means to screen, treat, and prevent NADCs in the future. This review presents data on the epidemiology and etiology of NADCs, as well as ongoing research into this evolving aspect of the HIV epidemic.

Abstract
Background The life expectancy of patients with HIV has increased significantly since the introduction of highly active antiretroviral therapy in 1995. Although this population of patients now carries less risk for the development of AIDS defining illnesses and malignancies, they are still at risk for non-AIDS defining cancers, such as colon, prostate, and breast. Several studies have shown that HIV infected patients have a higher prevalence of advanced colonic neoplasia which occur at a younger age. Our aim is to examine the prevalence of adenomas and adenocarcinoma in HIV patients undergoing colonoscopy. Methods HIV patients seen in our gastroenterology clinic and inpatient service undergoing colonoscopy were identified from 2010 - 2011. Indication was screening in 27 patients and diagnostic in 23 patients. Significant lesions were defined as adenomas, serrated polyps, and adenocarcinoma. Results Total 50 patients were included in the study, 32 male and 18 female (mean age: 53.6; range 37 - 72 years), 25 patients were African American, 21 were Hispanic, 3 were Caucasian, and one was Indian, 39 patients had undetectable HIV RNA, 30 patients had CD4 lymphocyte counts greater than 500, 20 had CD4 lymphocyte counts less than 500, and 4 patients had CD4 lymphocyte counts less than 200, 52% (26/50) of patients had polyps. Significant lesions (adenomas and serrated polyps) were seen in 34% (17/50) of patients, 39% in diagnostic and 30% in screening procedures (P = 0.56). Males were found to have significant lesions 28% of the time as compared to 44% of females (P = 0.35), 43% of Hispanics had significant lesions versus 24% of African Americans (P = 0.22), 25% of the patients under age 50 were found to have significant lesions, 45% of the patients with detectable HIV RNA levels were found to have significant lesions vs 31% (P = 0.48). Surprisingly, patients with CD4 counts > 500 had significantly more adenomas than those with CD4 counts < 500, 47% vs 15% (P = 0.03). No adenocarcinomas were seen in our patient population. Conclusion In our case series of HIV patients the adenoma detection rate was 34% overall, 45% in the patients with detectable HIV RNA levels, and 47% in patients with CD4 counts > 500. Additionally, there was a 25% adenoma detection rate in patients less than fifty years of age. This data reinforces the need for aggressive colon cancer screening in the HIV population.

Abstract
Background Some have suggested gays and lesbians may carry a greater burden of colorectal cancer. To date, individual sexual orientation data are not available in cancer surveillance registries. This prevents an assessment of differences in colorectal cancer incidence and mortality by sexual orientation, using individual-level data. Methods We use an ecological approach to examine differences in colorectal cancer incidence and mortality by county-level sexual orientation data. From the Surveillance, Epidemiology and End Results (SEER) Program we obtain population-based surveillance data on colorectal cancer incidence and mortality from 1996 to 2004. We use Census 2000 data on same-sex partnered households, a proxy of sexual orientation, to derive county-level sexual orientation data. Using multiple regression models, we examined the county-level association of sexual minority density with colorectal cancer incidence and mortality. Results After controlling for race and SES, we identify a significant positive association between greater density of sexual minority men and women and colorectal cancer incidence. With respect to colorectal cancer mortality, we identify a positive association with density of sexual minority men, but not women. Conclusions In the absence of surveillance data on sexual minority individuals, ecological analyses provide estimates of associations at the aggregate level, thereby providing crucial information for follow-up studies.

Abstract
Colorectal Cancer (CRC) is the second leading cause of cancer mortality in the United States. African Americans (AAs) have the highest incidence of CRC of any American ethnic group. Survival from CRC in AAs is lower than in Caucasians, and the mean age of CRC development in AAs is younger. The AA community also has a high rate of HIV infection, accounting for 50.3% of all cases despite making up only 13.6% of the population. This retrospective cohort study identified 17 AA HIV patients with CRC. The patients were matched with 42 HIV-negative CRC patients (controls), based on age, sex, and TNM stage. Data were obtained from 3 hospitals in New Jersey: St. Michael's Medical Center, Trinitas Medical Center and St. Joseph's Medical Center. The age, sex, HIV status, tumor site, stage, drug usage, Hepatitis C status, and survival outcome of subjects and controls were compared. Data from the Surveillance Epidemiology & End Results (SEER) specific to AAs were also compared. The mean age of CRC diagnosis was younger, 50.7 years (median: 52 years, range: 35-71 years), versus 59.42 years (median: 66 years) (P < 0.0001) in the SEER AA population. Of the patients, 29.4% were diagnosed with CRC at less than 45 years of age, versus only 6.35% of the SEER AA population (P < 0.0002). The male-to-female ratio was 11:6. Seven individuals used IV drugs, and 7 had hepatitis C. The mean CD4+ T-cell count was 510.81 cells/mm(3) (median 419). At the time of CRC diagnosis, the average duration of HIV infection was 7.6 years (range 0-22.4 years).Of patients, 87.5% had left-sided CRC, versus 57.55% of the SEER population (P < 0.024). Of the patients, 52.94% had stage III-IV, at diagnosis, versus 43.84% in SEER. There was no statistically significant survival difference between the cases and controls. In our cohort of HIV-infected AA's with CRC, the staging and outcome of CRC did not appear to be affected by the degree of immunosuppression. HIV-infected AA with CRC presented with a higher percentage of left-sided CRC than AA's without HIV. Additionally, AAs with HIV tended to be younger at the time of CRC diagnosis. Our findings suggest that screening for CRC should be offered to HIV-infected AAs before the age of 45, and that sigmoidoscopy with fecal occult blood testing might be an acceptable screening modality. However, the exact age of initiation, optimal frequency, and preferred method of screening (colonoscopy vs. sigmoidoscopy) in this population requires further study.

Abstract
BACKGROUND The high morbidity and mortality in African Americans associated with behavior-linked chronic diseases are well documented. METHODS We tested the efficacy of an intervention to increase multiple health-related behaviors in African Americans. In a multisite cluster-randomized controlled trial, groups of African American human immunodeficiency virus (HIV)-serodiscordant heterosexual couples in Atlanta (Georgia), Los Angeles (California), New York (New York), and Philadelphia (Pennsylvania) were allocated to an individual-focused health promotion that addressed multiple health-related behaviors or to a couple-focused HIV/sexually transmitted disease (STD) risk reduction intervention. Primary outcomes were adherence to fruit and vegetable consumption and physical activity guidelines assessed preintervention, immediately postintervention, and 6 and 12 months postintervention. Secondary outcomes included fatty food consumption, prostate and breast cancer screening, and alcohol use. Generalized estimating equations tested the efficacy of the health promotion intervention over the postintervention assessments. RESULTS Health promotion intervention participants were more likely to report consuming 5 or more servings of fruits and vegetables daily (rate ratio [RR], 1.38; 95% confidence interval [CI], 1.18 to 1.62) and adhering to physical activity guidelines (1.39; 1.22 to 1.59) compared with HIV/STD intervention participants. In the health promotion intervention compared with the HIV/STD intervention, participants consumed fatty foods less frequently (mean difference, -0.18; 95% CI, -0.30 to -0.07), more men received prostate cancer screening (RR, 1.51; 95% CI, 1.21 to 1.88), and more women received a mammogram (RR, 1.26; 95% CI, 1.06 to 1.50). Alcohol use did not differ between the intervention groups. CONCLUSION This trial demonstrates the efficacy of interventions targeting multiple health-related behaviors in African American HIV-seropositive and HIV-seronegative men and women. Trial Registration clinicaltrials.gov Identifier: NCT00644163.

Abstract
Since the beginning of the AIDS epidemic, models of HIV care have needed to be invented or modified as the needs of patients and communities evolved. Early in the epidemic, primary care and palliative care predominated; subsequently, the emergence of effective therapy for HIV infection led to further specialization and a focus on increasingly complex antiretroviral therapy as the cornerstone of effective HIV care. Over the past decade, factors including (1) an aging, long-surviving population; (2) multiple co-morbidities; (3) polypharmacy; and (4) the need for chronic disease management have led to a need for further evolution of HIV care models. Moreover, geographic diffusion; persistent disparities in timely HIV diagnosis, treatment access, and outcomes; and the aging of the HIV provider workforce also suggest the importance of reincorporating primary care providers into the spectrum of HIV care in the current era. Although some HIV-dedicated treatment centers offer comprehensive medical services, other models of HIV care potentially exist and should be developed and evaluated. In particular, primary care- and community-based collaborative practices-where HIV experts or specialists are incorporated into existing health centers-are one approach that combines the benefits of HIV-specific expertise and comprehensive primary care using an integrated, patient-centered approach.

Abstract
SUMMARY OBJECTIVE To investigate the prevalence and correlates of missed opportunities for addressing reproductive and mental health needs during patients' visits to primary healthcare facilities. METHODS We selected a random sample of participants from 14 of the 49 clinics in Cape Town's public health sector using stratified, cluster random sampling (n = 2618). Participants were screened to identify those at risk for unsafe sexual behaviour and a mental disorder (specifically substance use, depression, anxiety, and suicide). Information pertaining to whether or not respondents were asked about these issues during clinic visits during the previous year was elicited. The rates and correlates of missed opportunities for providing reproductive and mental health interventions were calculated. RESULTS The criteria of a strict definition of a missed opportunity for reproductive or mental health care information were fulfilled by 25% of the sample, while 46% met criteria for a looser definition. After adjusting for the effects of other variables in the model, men and Coloured respondents were more likely to have satisfied the definition of a missed opportunity for an intervention, while having completed high school and having children increased the likelihood of receiving an intervention. CONCLUSION Consultations with primary healthcare providers in which these issues are not discussed may represent missed opportunities. Persons presenting for routine care can be counselled, screened and, if required, treated. Interventions are needed at the patient, provider, and community levels to increase the opportunities to provide reproductive and mental health care to patients during routine visits.

Abstract
OBJECTIVES Among patients with HIV, the risk of death associated with different AIDS events has been quantified, but the risk of death associated with non-AIDS events has not been examined. We compared the risk of all-cause mortality following AIDS versus serious non-AIDS (SNA) events in the Strategies for Management of Antiretroviral Therapy (SMART) study and the Evaluation of Subcutaneous Proleukin in a Randomized International Trial (ESPRIT). DESIGN Data from 9583 HIV-infected participants, 5472 with a CD4 cell count more than 350 cells/microl enrolled in SMART and 4111 with a CD4 cell count 300 cells/microl or more enrolled in ESPRIT, were analyzed. METHODS Cumulative mortality 6 months after AIDS and SNA events (cardiovascular, renal, hepatic disease, and malignancies) was estimated using the Kaplan-Meier method. Cox models were used to estimate hazard ratios associated with AIDS and SNA events on the risk of death overall and by treatment group within study. RESULTS AIDS and SNA events occurred in 286 and 435 participants with 47 (16%) and 115 (26%) subsequent deaths, respectively. Six-month cumulative mortality was 4.7% [95% confidence interval (CI) 2.8-8.0] after experiencing an AIDS event and 13.4% (95% CI 10.5-17.0) after experiencing an SNA event. The adjusted hazard ratio for all-cause mortality for those who experienced AIDS versus those who did not was 4.9 (95% CI 3.6-6.8). The corresponding hazard ratio for SNA was 11.4 (95% CI 9.0-14.5) (P < 0.001 for difference in hazard ratios). Findings were similar for both treatment groups in SMART and both treatment groups in ESPRIT. CONCLUSION Among HIV-infected persons with higher CD4 cell counts, SNA events occur more frequently and are associated with a greater risk of death than AIDS events. Future research should be aimed at comparing strategies to reduce morbidity and mortality associated with SNA events for HIV-infected persons.

Abstract
We planned to investigate the recent trends for colorectal cancer (CRC) screening in human immunodeficiency virus (HIV) as compared to non-HIV by interviewing consecutive patients in outpatient clinics during September 2007. Out of a total of 300 patients interviewed, 205 met the inclusion criteria. One hundred and fourteen were HIV-infected, while 91 were non-HIV. HIV received more office visits per year. Despite the high incidence of adenomas on screening colonoscopy, HIV patients were less likely to undergo any type of CRC screening test. A higher number (>or=10) of annual clinic visits and the presence of co-morbid conditions were associated with being up-to-date for CRC screening in HIV patients. Conclusion CRC screening is underutilized in HIV patients. Multiple office visits per year are associated with being up-to-date for CRC screening. Hence, increasing patients' compliance with office visits and educating them about the importance of CRC screening may indirectly increase compliance with CRC screening.

Abstract
BACKGROUND Patients infected with Human immunodeficiency virus (HIV) living longer with antiretroviral therapy (ART) are more likely to develop non-AIDS-defining cancers such as adenocarcinoma of the colon. There have been limited case reports regarding HIV-associated colon adenocarcinoma. The aim of this study was to characterize the clinicopathologic findings and outcome in a series of HIV-infected patients diagnosed and treated for colon adenocarcinoma. PATIENTS AND METHODS A retrospective study involving HIV-related colon adenocarcinoma was performed. Cases were accrued from the personal archives and published case reports. Data regarding demographics, HIV acquisition, ART use, immunosuppression, cancer location, pathology, and outcome were extracted and analyzed. RESULTS A total of 17 patients were identified, including 7 personal cases. Patients were of average age 43 years (range, 25-67 years) and predominantly male (male:female ratio, 14:3). Most carcinomas (57%) involved the right colon, were largely TNM stage 4 cancers (47%), and, when present, metastases were mainly to the liver. Many (47%) individuals died within 1-26 months after their cancer diagnosis. Immunosuppression (AIDS diagnosis and/or CD4+ < 500 cells/mm3) did not appear to correlate with tumor grade, stage, or an adverse outcome. CONCLUSION These data show that HIV-infected patients with adenocarcinoma of the colon tend to be young men with a high incidence of right-sided involvement. Additional research is needed to determine if screening HIV-infected individuals for colon cancer should include younger patients and involve the entire colon.

Abstract
The use of antiretroviral therapy has reduced mortality and shifted the spectrum of malignancies affecting people living with HIV/AIDS (PLWH). We review guidelines and evidence for screening PLWH for non-AIDS-defining malignancies as compared with the general population. Cervical cancer screening clearly differs for HIV-seropositive women, with two Pap tests 6 months apart in the first year and then annually if normal. The role of cervical human papillomavirus screening has not yet been defined in HIV-seropositive women. Anal cancer screening consists of an annual digital rectal examination, and some (but not all) guidelines also recommend annual anal Pap tests. Screening for breast and colorectal cancer should follow standard, age-appropriate screening recommendations that apply to the general population. Screening HIV-infected men for prostate cancer, as with the general population, lacks a clear benefit. Despite increasing rates of hepatocellular carcinoma and lung cancers among PLWH, there is insufficient evidence to support routine screening.
