RESUMEN

OBJECTIVES: The present study investigates the impact of disrupted mental health services during the COVID-19 pandemic on depression and anxiety symptoms in long-term care (LTC) residents. METHODS: The study examined clinical data from 5,645 residents who received at least two psychological services in a long-term care (LTC) or assisted living (AL) setting between March 2019 and March 2021. A series of multiple regressions were run to explore the effects of the COVID-19 shutdown on depression and anxiety symptoms while examining the effects of COVID-19-related facility closure and facility telehealth capabilities. Follow-up regression analyses explored the impact of cognitive impairment and positive trauma history on depression and anxiety symptoms. RESULTS: Post-COVID levels of anxiety and depression were higher for residents with higher levels of pre-COVID anxiety and depression. The interaction between facility closure and availability of telehealth services and trauma history predicted self-report anxiety symptoms. Clinician-observed anxiety symptoms were predicted by cognitive impairment. Residents with a history of trauma had an increase in self-reported anxiety symptoms. CONCLUSIONS: Telehealth appeared to mitigate anxiety during the pandemic for residents with higher pre-COVID anxiety. CLINICAL IMPLICATIONS: For those individuals with severe anxiety, results suggest the importance of ensuring that mental health services are available to mitigate symptoms via telehealth when infection control disrupts the usual delivery of treatment.

RESUMEN

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has negatively impacted the mental health functioning of older adults residing in long-term care (LTC) settings. This study examines the impact of the lockdown on anxiety symptoms over time in LTC residents. DESIGN: Secondary data analysis was conducted on clinical data obtained with permission from a large behavioral health company that provides behavioral health services in long-term care (LTC) and assisted living (AL) facilities. SETTING AND PARTICIPANTS: Data were obtained from 1149 adults (mean age 72.37, 70% female) in LTC and AL facilities across the United States who were receiving psychological services 1 year prior, and 1 year after, the COVID-19 pandemic lockdown. METHODS: Changes in anxiety (measured using a clinician rating scale) over time before and after the pandemic were assessed using latent growth curve modeling with psychiatric diagnosis, psychiatric medication, and demographic factors included as covariates. RESULTS: Anxiety severity decreased over time before and after the onset of the COVID-19 pandemic. Although pandemic-level factors such as facility closure and telehealth availability did not affect anxiety over time, individual treatment factors such as obsessive compulsive disorder diagnosis, initial anxiety severity, bipolar disorder diagnosis, and prescriptions for anxiolytic and antipsychotic medications affected the trajectory of anxiety during the pandemic. CONCLUSIONS AND IMPLICATIONS: These results demonstrate that individual covariates such as diagnosis, symptom severity, and medication use impacted the trajectory of anxiety symptoms before and during the COVID-19 pandemic more strongly than pandemic-related circumstances (facility closure, telehealth availability). The impact of the COVID-19 pandemic may be better observed through treatment-relevant variables, rather than pure symptom severity. In preparation for future pandemics or other large-scale disasters potentially impacting service delivery, facilities should continue to prioritize continuity of care or a timely resumption of services attending to individual treatment factors.

RESUMEN

Cryptosporidium spp., protozoan parasites, are a leading cause of global diarrhea-associated morbidity and mortality in young children and immunocompromised individuals. The limited efficacy of the only available drug and lack of vaccines make it challenging to treat and prevent cryptosporidiosis. Therefore, the identification of essential genes and understanding their biological functions are critical for the development of new therapies. Currently, there is no genetic tool available to investigate the function of essential genes in Cryptosporidium spp. Here, we describe the development of the first conditional system in Cryptosporidium parvum Our system utilizes the Escherichia coli dihydrofolate reductase degradation domain (DDD) and the stabilizing compound trimethoprim (TMP) for conditional regulation of protein levels in the parasite. We tested our system on the calcium-dependent protein kinase-1 (CDPK1), a leading drug target in C. parvum By direct knockout strategy, we establish that cdpk1 is refractory to gene deletion, indicating its essentiality for parasite survival. Using CRISPR/Cas9, we generated transgenic parasites expressing CDPK1 with an epitope tag, and localization studies indicate its expression during asexual parasite proliferation. We then genetically engineered C. parvum to express CDPK1 tagged with DDD. We demonstrate that TMP can regulate CDPK1 levels in this stable transgenic parasite line, thus revealing the critical role of this kinase in parasite proliferation. Further, these transgenic parasites show TMP-mediated regulation of CDPK1 levels in vitro and an increased sensitivity to kinase inhibitor upon conditional knockdown. Overall, this study reports the development of a powerful conditional system that can be used to study essential genes in CryptosporidiumIMPORTANCECryptosporidium parvum and Cryptosporidium hominis are leading pathogens responsible for diarrheal disease (cryptosporidiosis) and deaths in infants and children below 5 years of age. There are no effective treatment options and no vaccine for cryptosporidiosis. Therefore, there is an urgent need to identify essential gene targets and uncover their biological function to accelerate the development of new and effective anticryptosporidial drugs. Current genetic tool allows targeted disruption of gene function but leads to parasite lethality if the gene is essential for survival. In this study, we have developed a genetic tool for conditional degradation of proteins in Cryptosporidium spp., thus allowing us to study the function of essential genes. Our conditional system expands the molecular toolbox for Cryptosporidium, and it will help us to understand the biology of this important human diarrheal pathogen for the development of new drugs and vaccines.
