New York State was the epicenter for COVID-19 in Spring 2020 when little was known about the pandemic. Dire circumstances necessitated New York State's (NYS) public mental health system to rapidly pivot, adapt, and innovate its policies and procedures to ensure continuous high-level care to individuals with serious mental illness (SMI), a population especially vulnerable to both the physical and psychosocial sequelae of COVID-19. NYS rapidly adopted emergency measures to support community providers, expanded the capacity of its State-Operated facilities, created policies to promote improved infection control access, collaborated to enhance the public-private continuum of service to support people with SMI, and broadened the use of new technologies to ensure continued engagement of care.

India with a population of 1.3 billion has a unique health care system in its different states. Mental health care varies widely across the country and this became even more apparent after the COVID-19 pandemic set in. This paper examines the various strategies in response to COVID-19 adopted by the Government of India, the health departments of the individual states, and other private players such as on-government organizations and the civil society. The cessation of many services including outpatient and inpatient care and the scarcity of medicines were serious impacts of COVID-19. The prolonged lockdown in many parts of the country impeded access to mental health care services since public transport was unavailable. This led to many relapses in persons with serious mental disorders. The emergence of new cases of psychosis and an increase in suicides were also seen. Tele consultations came to the fore and many helplines were started offering counseling and guidance regarding the availability of mental health care facilities. While these helped the urban dwellers, those in remote and rural areas were unable to use these services effectively. Many mental health wards were used for COVID-19 patients and mental health professionals were deployed for COVID-19 related duty. The severely mentally ill, the homeless mentally ill, and the elderly were especially vulnerable. Based on our experience with COVID-19, we urge a strong call for action, in terms of strengthening the primary care facilities and increasing the manpower resources to deliver mental health care.

The Coronavirus Disease 2019 (COVID-19) pandemic is a syndemic of viral infection and mental health adversity. The pandemic has exacerbated inequalities of access to care in vulnerable populations within the Canadian mental healthcare system. Primary care services are first-line health services in Canada, and are necessary to access specialized services. However, as a result of the limited availability of primary health services, and subsequently, specialized providers (eg, psychiatrists), the demand for these services outweigh the supply. Hitherto, timely access to appropriate services has been cited as a common challenge in Canada as a result of limitations as it relates to resources and in-person activities and support services. While there has been an increase in virtual care opportunities, concerns have been raised with respect to the digital divide. Moreover, while individuals with serious mental illness (SMI) and psychosis are at an increased risk for hospitalization and death from COVID-19, testing and vaccination services have not been prioritized for this population. Taken together, increased funding for mental health service delivery should be emphasized especially for individuals with SMI. There should also be a focus on increased collaboration among individuals with lived experience and health care providers to ensure future policies are developed specifically for this population. Addressing the social determinants of health and prioritizing a continuum of care across various stakeholders may lead to strong integration of care both during and after the pandemic.

Among individuals with psychotic disorders, paranoid ideation is common and associated with increased impairment, decreased quality of life, and a more pessimistic prognosis. Although accumulating research indicates negative affect is a key precipitant of paranoid ideation, the possible protective role of positive affect has not been examined. Further, despite the interpersonal nature of paranoid ideation, there are limited and inconsistent findings regarding how social context, perceptions, and motivation influence paranoid ideation in real-world contexts. In this pilot study, we used smartphone ecological momentary assessment to understand the relevance of hour-by-hour fluctuations in mood and social experience for paranoid ideation in adults with psychotic disorders. Multilevel modeling results indicated that greater negative affect is associated with higher concurrent levels of paranoid ideation and that it is marginally related to elevated levels of future paranoid ideation. In contrast, positive affect was unrelated to momentary experiences of paranoid ideation. More severe momentary paranoid ideation was also associated with an elevated desire to withdraw from social encounters, irrespective of when with familiar or unfamiliar others. These observations underscore the role of negative affect in promoting paranoid ideation and highlight the contribution of paranoid ideation to the motivation to socially withdraw in psychotic disorders.

Cognitive Adaptation Training (CAT) is a psychosocial treatment using environmental supports such as signs, checklists, technology, and the organization of belongings to bypass cognitive and motivational impairments for those with serious behavioral health problems. We conducted a survey of 204 members of managed Medicaid in Texas to examine the acceptability of, opinions about and preferences for CAT delivered in-person (CAT) or remotely (R-CAT) where supplies would be mailed and visits would occur via videoconferencing. The telephone survey presented descriptions of CAT and R-CAT in counterbalanced order eliciting general opinions about the treatments, such as (1) whether they would accept the treatments if they were offered the day of the survey at no cost, (2) which treatment was preferred, and (3) the extent to which they agreed or disagreed with a number of statements about components of the treatments. Results indicated that both R-CAT and CAT were acceptable to respondents with overall acceptance rates significantly higher for R-CAT 87% than for CAT (78%). With respect to preferences, 27% and 28% of respondents preferred CAT and R-CAT, respectively, and 41% of respondents preferred both equally. Black respondents more often preferred in-person CAT to other alternatives. Respondents agreed that they needed help, that they were comfortable with technology, and that they believed the programs would help them. The vast majority of qualitative comments about the treatments were positive. Results suggest that it will be important to assess the efficacy and effectiveness of CAT delivered remotely in randomized trials.

The COVID-19 pandemic mainly affected the most vulnerable individuals. Among those, patients with schizophrenia especially suffered from unexpected changes in their routines, barriers to treatment, and distress-related events. We conducted a narrative review using all available sources of information to describe the challenges faced by schizophrenia patients and their families in Brazil, including the strategies that have been adopted to tackle them. In addition, we analyzed public data on antipsychotic prescriptions and hospitalizations. It was found that digital prescriptions with extended expiration dates implemented during the pandemic in Brazil allowed patients to maintain their access to antipsychotics. Hospitalizations among patients with schizophrenia, schizotypal, and schizoaffective disorders decreased at the beginning of the pandemic. Nevertheless, in the following months, the admissions returned to a trend similar to the prepandemic period. The systematization of online resources will be one of the main legacies to mental health care, including schizophrenia. We believe one of the main limitations of the policies adopted was the decision to not prioritize COVID-19 vaccination in patients with severe psychiatric disorders, despite preliminary evidence of a higher risk of complications in this group. The coronavirus pandemic is still ongoing and a longer time will be required to have a better perspective of its effects, but we expect this record of challenges and insights about the lessons learned during the pandemic can help healthcare professionals to face similar situations in the future.

Background: Telemedicine adoption has grown significantly due to the coronavirus of 2019 pandemic; however, it remains unclear what the impact of widespread telemedicine use is on healthcare utilization among individuals with psychosis.

Objectives: To investigate the impact of telemedicine use on changes in healthcare utilization among patients with chronic psychotic disorders (CPDs).

Study design: We conducted a population-based, retrospective propensity-matched cohort study using healthcare administrative data in Ontario, Canada. Patients were included if they had at least one ambulatory visit between March 14, 2020 and September 30, 2020 and a CPD diagnosis any time before March 14, 2020. Telemedicine users (2+ virtual visits after March 14, 2020) were propensity score-matched 1:1 with standard care users (minimum of 1 in-person or virtual ambulatory visit and maximum of 1 virtual visit after March 14, 2020) based on several baseline characteristics. Monthly use of various healthcare services was compared between the two groups from 12 months before to 3 months after their index in-person or virtual ambulatory visit after March 14, 2020 using generalized estimating equations (eg, hospitalizations, emergency department [ED] visits, and outpatient physician visits). The slope of change over the study period (ie, rate ratio) as well as a ratio of slopes, were calculated for both telemedicine and standard care groups for each outcome.

Study results: A total of 18 333 pairs of telemedicine and standard care patients were identified after matching (60.8% male, mean [SD] age 45.4 [16.3] years). There was a significantly greater decline across time in the telemedicine group compared to the standard care group for ED visits due to any psychiatric conditions (ratio of slopes for telemedicine vs standard care (95% CI), 0.98 (0.98 to 0.99)). However, declines in primary care visit rates (ratio of slopes for telemedicine vs standard care (1.01 (1.01 to 1.02)), mental health outpatient visits with primary care (1.03 (1.03 to 1.04)), and all-cause outpatient visits with primary care (1.01 (1.01 to 1.02)), were steeper among the standard care group than telemedicine group.

Conclusions: Overall, patients with CPDs appeared to benefit from telemedicine as evidenced by increased outpatient healthcare utilization and reductions in ED visits due to psychiatric conditions. This suggests that telemedicine may have allowed this patient group to have better access and continuity of care during the initial waves of the pandemic.

Research indicates that most people with Schizophrenia from low to middle-income countries do not receive adequate healthcare. Inadequate policies, lack of funding, poor service planning and neglect are some barriers to adequate care. Intrinsic barriers to care include stigma, lack of insight, and pathways to care that are often driven by cultural beliefs, and many systemic challenges. South Africa was not spared from the scourge of COVID-19, hosting a third of all reported cases in Africa. In a country with disparities, it would be of interest to get insight into the situation concerning the healthcare needs of people with Schizophrenia during the pandemic. A pandemic such as COVID-19 placed enormous strains on already limited and unequally distributed health care resources. In this paper, we discuss: (1) The South African healthcare system (with respect to Schizophrenia care). (2) COVID-19 policies related to the care of people with Schizophrenia (testing, access to vaccine). (3) Managing people with Schizophrenia amid the COVID-19 pandemic. (4) Recommendations.

Background: High expressed emotion (EE) experienced by people with mental illness is a known risk factor of relapse. With drastically increased time spent at home and limited health and social service provision during the COVID-19 pandemic, patients' experience of high EE warranted attention.

Aims and methods: The study aimed to investigate the experience of high EE among people with mental illness during the COVID-19 pandemic. We surveyed the service users of 2 community mental health centers, including participants with psychotic and nonpsychotic disorders.

Results: Valid responses from 303 participants indicated an overall high EE prevalence of 71.62%, much higher than previous findings, which range between 30% and 40%. People with other psychotic and nonpsychotic disorders showed a higher probability of experiencing high EE than people with schizophrenia. Participants reported a higher probability of experiencing high EE as a result of caregiving by other family relatives and friends than by parents.

Conclusion: Findings suggest a significantly elevated high EE prevalence among people suffering from mental illness in the community during the COVID-19 pandemic. It is worth further evaluating the long-term effects of high EE beyond the pandemic.

Background and hypotheses: Hippocampal replay and associated high-frequency ripple oscillations are among the best-characterized phenomena in resting brain activity. Replay/ripples support memory consolidation and relational inference, and are regulated by N-methyl-D-aspartate receptors (NMDARs). Schizophrenia has been associated with both replay/ripple abnormalities and NMDAR hypofunction in both clinical samples and genetic mouse models, although the relationship between these 2 facets of hippocampal function has not been tested in humans.

Study design: Here, we avail of a unique multimodal human neuroimaging data set to investigate the relationship between the availability of (intrachannel) NMDAR binding sites in hippocampus, and replay-associated ripple power, in 16 participants (7 nonclinical participants and 9 people with a diagnosis of schizophrenia, PScz). Each participant had both a [¹⁸F]GE-179 positron emission tomography (PET) scan (to measure NMDAR availability, V _T ) and a magnetoencephalography (MEG) scan (to measure offline neural replay and associated high-frequency ripple oscillations, using Temporally Delayed Linear Modeling).

Study results: We show a positive relationship between hippocampal NMDAR availability and replay-associated ripple power. This linkage was evident across control participants (r(5) = .94, P = .002) and PScz (r(7) = .70, P = .04), with no group difference.

Conclusions: Our findings provide preliminary evidence for a relationship between hippocampal NMDAR availability and replay-associated ripple power in humans, and haverelevance for NMDAR hypofunction theories of schizophrenia.
