Racial and Ethnic Differences in Subjective Cognitive Decline - United States, 2015-2020.

Subjective cognitive decline (SCD), the self-reported experience of worsening or more frequent memory loss or confusion, might be a symptom of early-stage dementia or future serious cognitive decline such as Alzheimer disease* or a related dementia (ADRD) (1). Established modifiable risk factors for ADRD include high blood pressure, inadequate physical activity, obesity, diabetes, depression, current cigarette smoking, and hearing loss (2). An estimated 6.5 million persons aged ≥65 years in the United States live with Alzheimer disease, the most common dementia (1). This number is projected to double by 2060, with the largest increase among non-Hispanic Black or African American (Black), and Hispanic or Latino (Hispanic) adults (1,3). Using data from the Behavioral Risk Factor Surveillance System (BRFSS), CDC assessed racial and ethnic, select demographic, and geographical differences in SCD prevalence, and prevalence of health care professional conversations among those reporting SCD. The age-adjusted prevalence of SCD during 2015-2020 was 9.6% among adults aged ≥45 years (5.0% of Asian or Pacific Islander [A/PI] adults, 9.3% of non-Hispanic White [White] adults, 10.1% of Black adults, 11.4% of Hispanic adults, and 16.7% of non-Hispanic American Indian or Alaska Native [AI/AN] adults). College education was associated with a lower prevalence of SCD among all racial and ethnic groups. Only 47.3% of adults with SCD reported that they had discussed confusion or memory loss with a health care professional. Discussing changes in cognition with a physician can allow for the identification of potentially treatable conditions, early detection of dementia, promotion of dementia risk reduction behaviors, and establishing a treatment or care plan to help adults remain healthy and independent for as long as possible.

Epidemiology of syphilis in the Nepean and Blue Mountains Local Health District between 1 October 2009 and 30 September 2019.

Background: Syphilis is a nationally notifiable sexually transmitted infection (STI). Rates of syphilis notifications have been on the increase in Australia. Given these increases, we wanted to study the epidemiological trends of syphilis notifications in the Nepean Blue Mountain Local Health District (NBMLHD) over a ten-year period across different healthcare settings. Methods: All syphilis notifications in residents in the NBMLHD in the ten-year period between 1 October 2009 and 30 September 2019 were included in the study. Separate analyses were performed for all syphilis notifications, as well as for infectious syphilis and for syphilis acquired > 2 years ago or of unknown duration. We described age distribution and demographic profile and risk factors of all syphilis notifications. Notification trends were studied and crude incidence rates were calculated. Notifications were stratified by stage of syphilis, sex, and geographical location. Results: In the study duration, a total of 342 notifications of syphilis were received. Of these, 187 were infectious syphilis and 155 were related to infections acquired > 2 years ago and/or of unknown duration. The majority of notifications were in men: 281 (82%). Overall, syphilis notifications increased over the ten-year study period. The crude incidence rates for infectious syphilis were significantly higher in the second five-year period overall (7.78/100,000 population per year compared to 5.28/100,000 population per year; incidence rate ratio (IRR): 1.47; 95% confidence interval (95% CI): 1.10-1.97; p < 0.01), as well as for males (14.44/100,000 population per year compared to 9.7/100,000 population per year; IRR: 1.49; 95% CI: 1.09-2.03; p < 0.01). There were significant increases in syphilis notifications in males < 35 years of age, from 39 such notifications in the first five-year period (27.5% of all syphilis notifications in this period) to 83 notifications in the second five-year period (42.1% of all notifications in this period), p < 0.05. Conclusion: In keeping with national trends, notifications in our study increased. Significant increases were noted in notifications among males under 35 years of age. This supports the continued investment in sexual health promotion activities aimed at young sexually active men. Expansion of screening activities to include women and older people would help detect any increase in cases in these groups. Increase in engagement with general practitioners will support them to provide opportunistic STI screens to sexually-active attendees. National screening recommendations remain applicable to this population.

Prevalence and Characteristics of Arthritis Among Caregivers - 17 States, 2017 and 2019.

Caregiving provides numerous benefits to both caregivers and care recipients; however, it can also negatively affect caregivers' mental and physical health (1-4), and caregiving tasks often require physical exertion (1). Approximately 44% of adults with arthritis report limitations attributable to arthritis, including trouble doing daily activities (5). These limitations might affect caregivers' ability to provide care, but little is known about arthritis among caregivers. To assess arthritis among caregivers of a family member or friend, CDC examined data from 17 states that administered both the arthritis and caregiving modules as part of the Behavioral Risk Factor Surveillance System (BRFSS) in either 2017 or 2019. Approximately one in five adults (20.6%) was a caregiver. Prevalence of arthritis was higher among caregivers (35.1%) than noncaregivers (24.5%). Compared with caregivers without arthritis, those with arthritis provided similar types of care and were more likely to have provided care for ≥5 years and for ≥40 hours per week. In addition, higher proportions of caregivers with arthritis reported disabilities compared with those without arthritis, including mobility issues (38.0% versus 7.3%). Arthritis among caregivers might affect their own health as well as the care they can provide. Caregivers can discuss their arthritis and related limitations with a health care professional to identify ways to increase their physical activity and participation in lifestyle management programs.* Such interventions might ease arthritis pain and related limitations and might support them in their ongoing caregiving role. Public health professionals can implement strategies to support caregivers throughout the caregiving process.†.

Population-level effectiveness of rapid, targeted, high-coverage roll-out of HIV pre-exposure prophylaxis in men who have sex with men: the EPIC-NSW prospective cohort study.

BACKGROUND: HIV pre-exposure prophylaxis (PrEP) is highly effective in men who have sex with men (MSM) at the individual level, but data on population-level impact are lacking. We examined whether rapid, targeted, and high-coverage roll-out of PrEP in an MSM epidemic would reduce HIV incidence in the cohort prescribed PrEP and state-wide in Australia's most populous state, New South Wales. METHODS: The Expanded PrEP Implementation in Communities-New South Wales (EPIC-NSW) study is an implementation cohort study of daily co-formulated tenofovir disoproxil fumarate and emtricitabine as HIV PrEP. We recruited high-risk gay men in a New South Wales-wide network of 21 clinics. We report protocol-specified co-primary outcomes at 12 months after recruitment of the first 3700 participants: within-cohort HIV incidence; and change in population HIV diagnoses in New South Wales between the 12-month periods before and after PrEP roll-out. The study is registered with ClinicalTrials.gov, number NCT02870790. FINDINGS: We recruited 3700 participants in the 8 months between March 1, 2016, and Oct 31, 2016. 3676 (99%) were men, 3534 (96%) identified as gay, and 149 (4%) as bisexual. Median age was 36 years (IQR 30-45 years). Overall, 3069 (83%) participants attended a visit at 12 months or later. Over 4100 person-years, two men became infected with HIV (incidence 0·048 per 100 person-years, 95% CI 0·012-0·195). Both had been non-adherent to PrEP. HIV diagnoses in MSM in New South Wales declined from 295 in the 12 months before PrEP roll-out to 221 in the 12 months after (relative risk reduction [RRR] 25·1%, 95% CI 10·5-37·4). There was a decline both in recent HIV infections (from 149 to 102, RRR 31·5%, 95% CI 11·3 to 47·3) and in other HIV diagnoses (from 146 to 119, RRR 18·5%, 95% CI -4·5 to 36·6). INTERPRETATION: PrEP implementation was associated with a rapid decline in HIV diagnoses in the state of New South Wales, which was greatest for recent infections. As part of a combination prevention approach, rapid, targeted, high-coverage PrEP implementation is effective to reduce new HIV infections at the population level.

Health risk and health seeking behaviours among people who inject performance and image enhancing drugs who access needle syringe programs in Australia.

INTRODUCTION AND AIMS: People who use performance and image enhancing drugs (PIED) are a growing population in needle syringe programs (NSP) in Australia. Previous international research has identified heterogeneity among the PIED-using population. This study investigated health behaviours among NSP attendees who had recently (last 12 months) injected PIEDs and examined differences among this group according to recent psychoactive drug use. DESIGN AND METHODS: The Australian Needle and Syringe Program Survey is an annually repeated cross-sectional survey conducted at approximately 50 NSPs nationally. In 2015, respondents provided information on their demographic characteristics, health risk and health monitoring behaviours, and provided a capillary dried blood spot for HIV and hepatitis C virus antibody testing. Univariable and multivariable logistic regressions assessed factors associated with recent (last 12 months) use (all routes of administration) of psychoactive drugs. RESULTS: Among recent PIED injectors (n = 156), 59% had recently used psychoactive substances. Those who had recently used psychoactive drugs were significantly younger, less educated and more likely to have experienced redness at an injection site in the previous 12 months but were more likely to report recent HIV/hepatitis C virus testing. DISCUSSION AND CONCLUSIONS: This study identified significant differences in demographic characteristics, risk and health seeking behaviour among PIED users who did and did not also use psychoactive substances. There is a need to enhance and tailor harm reduction efforts and to build the capacity of NSP staff to better meet the needs of this diverse group.

High rates of sexually transmissible infections in HIV-positive patients in the Australian HIV Observational Database: a prospective cohort study.

UNLABELLED: Background In HIV-positive people, sexually transmissible infections (STIs) probably increase the infectiousness of HIV. METHODS: In 2010, we established a cohort of individuals (n=554) from clinics in the Australian HIV Observational Database (AHOD). We calculated retrospective rates for four STIs for 2005-10 and prospective incidence rates for 2010-11. RESULTS: At baseline (2010), patient characteristics were similar to the rest of AHOD. Overall incidence was 12.5 per 100 person-years. Chlamydial infections increased from 3.4 per 100 person-years (95% confidence interval (CI): 1.9-5.7) in 2005 to 6.7 per 100 person-years (95% CI: 4.5-9.5) in 2011, peaking in 2010 (8.1 per 100 person-years; 95% CI: 5.6-11.2). Cases were distributed among rectal (61.9%), urethral (34%) and pharyngeal (6.3%) sites. Gonococcal infections increased, peaking in 2010 (4.7 per 100 person-years; 95% CI: 5.6-11.2; Ptrend=0.0099), distributed among rectal (63.9%), urethral (27.9%) and pharyngeal (14.8%) sites. Syphilis showed several peaks, the largest in 2008 (5.3 per 100 person-years; 95% CI: 3.3-8.0); the overall trend was not significant (P=0.113). Genital warts declined from 7.5 per 100 person-years (95% CI: 4.8-11.3) in 2005 to 2.4 per 100 person-years (95% CI: 1.1-4.5) in 2011 (Ptrend=0.0016). CONCLUSIONS: For chlamydial and gonococcal infections, incidence was higher than previous Australian estimates among HIV-infected men who have sex with men, increasing during 2005-2011. Rectal infections outnumbered infections at other sites. Syphilis incidence remained high but did not increase; that of genital warts was lower and decreased.

What proportion of sexually transmissible infections and HIV are diagnosed in New South Wales' public sexual health services compared with other services?

BACKGROUND: In New South Wales (NSW), publicly funded sexual health services (PFSHSs) target the populations at greatest risk for important sexually transmissible infections (STIs) and so may make a large contribution to the diagnosis of notifiable STIs. We aimed to determine the proportions of STIs diagnosed in PFSHSs and notified to the NSW Ministry of Health in 2009, and describe geographical variations. METHODS: The number of notifiable STIs (infectious syphilis, gonorrhoea, HIV and chlamydia) diagnosed in 2009 was obtained for each Area Health Service (AHS) and each PFSHS. The proportion of diagnoses made by PFSHSs was calculated at the state and AHS level according to five geographical regions: inner and outer metropolitan, regional, rural and remote. RESULTS: The overall proportions of diagnoses made by NSW PFSHSs were syphilis, 25%; gonorrhoea, 25%; HIV, 21%; and chlamydia, 14%. Within each zone, the proportions of these STIs were (respectively): (i) inner metropolitan: 32%, 26%, 21% and 13%; (ii) outer metropolitan: 41%, 24%, 43% and 9%; (iii) regional: 62%, 15%, 23% and 10%; (iv) rural: 8%, 29%, <5% and 20%; and (v) remote: <5%, 43%, <5% and 29%. There was considerable variation in proportions of STIs between and within AHSs (<5-100%). CONCLUSIONS: NSW PFSHSs contribute a large proportion of diagnoses for syphilis, gonorrhoea and HIV, but less so for chlamydia. Across AHSs and zones, there was considerable variation in the proportions. These data support the role of PFSHS in identifying and managing important STIs in high-risk populations.
