Guiding the Implementation of Wastewater-based Surveillance for Carceral Infection Control with Perspectives from People with Lived Experience of Incarceration during the COVID-19 Pandemic.

Background: Little guidance exists on best practices for implementing and sustaining wastewater-based surveillance (WBS) for SARS-CoV-2 in carceral settings. To ensure alignment with priorities of stakeholders, we aimed to understand the perspectives of persons with lived experience (PLE) of jail who were incarcerated during the height of the COVID-19 pandemic on infection control. Methods: We recruited two PLE at each of four jails: Cook County (IL), Fulton County (GA), Middlesex County (MA), and Washington DC. Focus Group Discussion (FGD) guides followed the Consolidated Framework for Implementation Research (CFIR). Two FGDs focusing on lived experience with jail infection control protocol and WBS were conducted, and six Key Informant (KI) interviews followed to gain insights on communicating WBS results. We used a combination of deductive thematic analysis based on CFIR constructs and inductive analysis to capture emergent themes. Results: Themes from FGDs included: (1) variable experiences with COVID-19 infection control protocols including intake processes, individual testing, isolation and quarantine, (2) the perceived attitudes of fellow residents and staff surrounding COVID-19 mitigation in a carceral setting; and (3) perceived benefits and challenges involving WBS implementation and messaging. KIs emphasized 1) The importance of straightforward health messaging and trustworthiness in the communication of WBS results, 2) Support for enhanced health education around outbreaks, and 3) Receptiveness to WBS being used as a tool to measure common infectious agents (i.e., influenza) but hesitancy regarding its application to conditions such as HIV and illicit drug use. PLE articulated support of robust infection control programs and receptiveness to expanding WBS if conducted in a non-stigmatizing manner. Conclusion: Perspectives from PLE can help shape the infection control programs for future outbreaks and inform the expansion of WBS implementation in carceral facilities. It will be important to consider the voices of current and former residents, as receivers of care, to promote an environment conducive to comprehensive infection control. In addition to having infection control programs consistently execute set protocols and educate all stakeholders, PLE identified collaboration between jail staff and residents, and clear communication around program expectations as priorities. Findings from this qualitative study can be shared with jail decision makers and the perceived engagement of stakeholders can be measured.

Toxoplasma gondii Effects on the Relationship of Kynurenine Pathway Metabolites to Acoustic Startle Latency in Schizophrenia vs. Control Subjects.

Background: Chronic infection with Toxoplasma gondii (TOXO) results in microcysts in the brain that are controlled by inflammatory activation and subsequent changes in the kynurenine pathway. TOXO seropositivity is associated with a heightened risk of schizophrenia (SCZ) and with cognitive impairments. Latency of the acoustic startle response, a putative index of neural processing speed, is slower in SCZ. SCZ subjects who are TOXO seropositive have slower latency than SCZ subjects who are TOXO seronegative. We assessed the relationship between kynurenine pathway metabolites and startle latency as a potential route by which chronic TOXO infection can lead to cognitive slowing in SCZ. Methods: Fourty-seven SCZ subjects and 30 controls (CON) were tested on a standard acoustic startle paradigm. Kynurenine pathway metabolites were measured using liquid chromatography-tandem mass spectrometry were kynurenine (KYN), tryptophan (TRYP), 3-hydroxyanthranilic acid (3-OHAA), anthranilic acid (AA), and kynurenic acid (KYNA). TOXO status was determined by IgG ELISA. Results: In univariate ANCOVAs on onset and peak latency with age and log transformed startle magnitude as covariates, both onset latency [F(1,61) = 5.76; p = 0.019] and peak latency [F(1,61) = 4.34; p = 0.041] were slower in SCZ than CON subjects. In stepwise backward linear regressions after stratification by Diagnosis, slower onset latency in SCZ subjects was predicted by higher TRYP (B = 0.42; p = 0.008) and 3-OHAA:AA (B = 3.68; p = 0.007), and lower KYN:TRYP (B = -185.42; p = 0.034). In regressions with peak latency as the dependent variable, slower peak latency was predicted by higher TRYP (B = 0.47; p = 0.013) and 3-OHAA:AA ratio (B = 4.35; p = 0.010), and by lower KYNA (B = -6.67; p = 0.036). In CON subjects neither onset nor peak latency was predicted by any KYN metabolites. In regressions stratified by TOXO status, in TOXO positive subjects, slower peak latency was predicted by lower concentrations of KYN (B = -8.08; p = 0.008), KYNA (B = -10.64; p = 0.003), and lower KYN:TRYP ratios (B = -347.01; p = 0.03). In TOXO negative subjects neither onset nor peak latency was predicted by any KYN metabolites. Conclusions: KYN pathway markers predict slowing of startle latency in SCZ subjects and in those with chronic TOXO infection, but this is not seen in CON subjects nor TOXO seronegative subjects. These findings coupled with prior work indicating a relationship of slower latency with SCZ and TOXO infection suggest that alterations in KYN pathway markers may be a mechanism by which neural processing speed, as indexed by startle latency, is affected in these subjects.

Indoor gardening older adults: effects on socialization, activities of daily living, and loneliness.

This study examined the effects of indoor gardening on socialization, activities of daily living (ADLs), and perceptions of loneliness in elderly nursing home residents. A total of 66 residents from two nursing homes participated in this two-phase study. In phase one, experimental group 1 participated once a week for 5 weeks in gardening activities while a control group received a 20-minute visit. While no significant differences were found between groups in socialization or perceptions of loneliness, there were significant pretest-posttest differences within groups on loneliness and guidance, reassurance of worth, social integration, and reliable alliance. The results also demonstrated gardening interventions had a significant effect on three ADLs (transfer, eating, and toileting). Phase two examined differences in the effects of a 5-week versus a 2-week intervention program. Although no significant within-group differences were noted in socialization, loneliness, or ADLs, the 5-week program was more effective in increasing socialization and physical functioning.
