[Pharmacological trials evaluating treatment options for neuropsychiatric symptoms in post-COVID. A narrative review]. / Essais pharmacologiques sur les traitements des symptômes neuropsychiatriques du post-Covid. Revue narrative de la littérature.

Post-COVID prevalence's is estimated at 10 % in the general population. The neuropsychiatric symptoms, which are frequent (up to 30 %), can severely affect the quality of life of patients affected by this condition, notably by significantly reducing their working ability. To date, no pharmacologic treatment is available for post-COVID, apart from symptomatic treatments. A large number of pharmacological clinical trials for post-COVID are underway since 2021. A number of these trials targets neuropsychiatric symptoms, based on the various underlying pathophysiological hypotheses. The objective of this narrative review is to provide an overview of these ongoing trials targeting neuropsychiatric symptoms in post-COVID.

La prévalence du syndrome post-Covid est évaluée à 10 % dans la population générale. Les symptômes neuropsychiatriques, fréquents (jusqu'à 30 %), peuvent sévèrement affecter la qualité de vie des patients qui en sont atteints et, notamment, en réduisant significativement leur capacité de travail. À ce jour, il n'existe pas de traitement médicamenteux pour le syndrome post-Covid, en dehors des traitements symptomatiques. C'est pourquoi, un grand nombre d'essais thérapeutiques concernant le post-Covid sont en cours depuis 2021. Un certain nombre d'entre eux ciblent les symptômes neuropsychiatriques en se basant sur les diverses hypothèses physiopathologiques élaborées sur le post-Covid. L'objectif de cette revue narrative est d'établir un état des lieux des essais thérapeutiques en cours ciblant les symptômes neuropsychiatriques du post-Covid.

[Follow-up of patients after COVID-19 pneumonia. Pulmonary sequelae]. / Seguimiento de los pacientes después de neumonía por COVID-19. Secuelas pulmonares.

Coronavirus disease 2019 (COVID-19) is an infection caused by SARS-CoV-2 that has caused an unprecedented pandemic with a high rate of morbidity and mortality worldwide. Although most cases are mild, there are a considerable number of patients who develop pneumonia or even acute respiratory distress syndrome (ARDS). After having recovered from the initial disease, many patients continue with various symptoms (fatigue, dry cough, fever, dyspnea, anosmia, and chest pain, among others.), which has led to consider the possible existence of "post-COVID-19 syndrome". Although the definition and validity of this syndrome are not clear yet, several studies report that individuals who have recovered from COVID-19 may have persistent symptoms, radiological abnormalities, and compromised respiratory function. Current evidence suggests that there is a large number of pulmonary sequelae after COVID-19 pneumonia (interstitial thickening, ground glass opacities, crazy paving pattern, and bronchiectasis, among others.). Likewise, it seems that pulmonary function tests (spirometry, DLCO, 6MWT, and measurement of maximum respiratory pressures), in addition to high-resolution computed axial tomographies (CAT scan), are useful for the assessment of these post-COVID-19 pulmonary sequelae. This review aims to describe the possible pulmonary sequelae after COVID-19 pneumonia, as well as to suggest diagnostic procedures for their correct assessment and follow-up; thus, allowing proper management by a multidisciplinary medical team.

COVID-19 es la enfermedad causada por el virus SARS-CoV-2, la cual ha ocasionado una pandemia sin precedentes, con gran cantidad de infectados y muertos en el mundo. Aunque la mayoría de los casos son leves, existe una cantidad considerable de pacientes que desarrollan neumonía o, incluso, síndrome de distrés respiratorio agudo (SDRA). Luego de recuperarse del cuadro inicial, muchos pacientes continúan con diversos síntomas (fatiga, tos seca, fiebre, disnea, anosmia, dolor torácico, entre otras), lo que ha llevado a considerar la posible existencia del "síndrome pos-COVID-19". Aunque la definición y validez de este síndrome aún no son claras, varios estudios reportan que los individuos recuperados de la COVID-19 pueden tener persistencia de síntomas, anormalidades radiológicas y compromiso en la función respiratoria. La evidencia actual sugiere que existe gran cantidad de secuelas pulmonares despues de una neumonía por COVID-19 (engrosamiento intersticial, infiltrado en vidrio esmerilado, patrón en empedrado, bronquiectasias, entre otras.). De igual forma, parece ser que las pruebas de función pulmonar (espirometría, prueba de difusión pulmonar de monóxido de carbono, prueba de caminata de seis minutos y la medición de las presiones respiratorias máximas), además de la tomografía axial computarizada de alta resolución, son útiles para evaluar las secuelas pulmonares pos-COVID-19. En esta revisión se pretende describir las posibles secuelas a nivel pulmonar posteriores a neumonía por COVID-19, así como sugerir procedimientos diagnósticos para su correcta evaluación y seguimiento, que permitan el manejo adecuado por parte de un equipo médico multidisciplinario.

New determinants of mental health: the role of noise pollution. A narrative review.

Urbanisation processes and anthropogenic actions led to a significant increase in pollution levels, with relevant consequences on global health. In particular, noise pollution demonstrated an association with cardiovascular, metabolic, and respiratory diseases. Furthermore, increasing evidence underlined the possible role of air and noise pollution in the development of psychiatric disorders. In this narrative review, evidence concerning the relationship between noise pollution and the emergence of psychiatric symptoms or psychiatric disorders is summarised. After the literature search process was completed, 40 papers were included in the present review. The exposure to road-, rail-, and air- traffic represented a risk factor for the emergence of affective disorders. This could also be mediated by the occurrence of circadian rhythms disturbances or by noise annoyance and noise sensitivity, both influencing psychological well-being and health-related quality of life. Fewer studies concentrated on special populations, particularly pregnant women and children, for whom noise pollution was confirmed as a risk factor for psychopathology. The better clarification of the complex interaction between noise pollution and mental health may help to identify subjects at risk and targeting specific prevention and intervention strategies in the urban environment.

Long-COVID syndrome: physical-mental interplay in the spotlight.

Patients suffering from Long-COVID syndrome experience a variety of different symptoms on a physical, but also on a psychological and social level. Previous psychiatric conditions such as depression and anxiety have been identified as separate risk factors for developing Long-COVID syndrome. This suggests a complex interplay of different physical and mental factors rather than a simple cause-effect relationship of a specific biological pathogenic process. The biopsychosocial model provides a foundation for understanding these interactions and integrating them into a broader perspective of the patient suffering from the disease instead of the individual symptoms, pointing towards the need of treatment options on a psychological as well as social level besides biological targets. This leads to our conclusion, that the biopsychosocial model should be the underlying philosophy of understanding, diagnosing and treating patients suffering from Long-COVID syndrome, moving away from the strictly biomedical understanding suspected by many patients, treaters and the media while also reducing the stigma still associated with the suggestion of a physical-mental interplay.

[COVID-19 and mental health services in Europe]. / COVID-19 e servizi di salute mentale in Europa.

The area of mental health is directly affected by the pandemic and its consequences, for various reasons: 1-the pandemic triggered a global lockdown, with dramatic socioeconomic and therefore psychosocial implications; 2-mental health services, which treat by definition a fragile population from the psychological, biological and social points of view, have a complex organizational frame, and it was expected that this would be affected (or overwhelmed) by the pandemic; 3-mental health services should, at least in theory, be able to help guide public health policies when these involve a significant modification of individual behaviour. It was conducted a narrative review of the publications produced by European researchers in the period February-June 2020 and indexed in PubMed. A total of 34 papers were analyzed, which document the profound clinical, organizational and procedural changes introduced in mental health services following this exceptional and largely unforeseen planetary event.Among the main innovations recorded everywhere, the strong push towards the use of telemedicine techniques should be mentioned: however, these require an adequate critical evaluation, which highlights their possibilities, limits, advantages and disadvantages instead of simple triumphalist judgments. Furthermore, should be emphasized the scarcity of quantitative studies conducted in this period and the absence of studies aimed, for example, at exploring the consequences of prolonged and forced face-to-face contact between patients and family members with a high index of "expressed emotions".

Psychological and Coping Responses of Health Care Workers Toward Emerging Infectious Disease Outbreaks: A Rapid Review and Practical Implications for the COVID-19 Pandemic.

OBJECTIVE: In light of the current evolving coronavirus disease 2019 (COVID-19) pandemic, and the need to learn from past infectious disease outbreaks to provide better psychological support for our frontline health care workers (HCW), we conducted a rapid review of extant studies that have reported on both psychological and coping responses in HCW during recent outbreaks. DATA SOURCES: We performed a systematic search of the available literature using PubMed, MEDLINE (Ovid), and Web of Science, combining key terms regarding recent infectious disease outbreaks and psychological and coping responses. Papers published from database inception to April 20, 2020, were considered for inclusion. Only studies in the English language and papers from peer-reviewed journals were included. STUDY SELECTION: We identified 95 (PubMed) and 49 papers (Web of Science) from the database search, of which 23 papers were eventually included in the review. DATA EXTRACTION: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used for data extraction. The McMaster University critical appraisal tool was used to appraise quantitative studies. Guidelines by Higginbotham and colleagues were used to appraise qualitative studies. Only studies exploring the combined psychological and coping responses of HCW amid infectious diseases were included. RESULTS: Salient psychological responses that can persist beyond the outbreaks included anxiety/fears, stigmatization, depression, posttraumatic stress, anger/frustration, grief, and burnout, but also positive growth and transformation. Personal coping methods (such as problem solving, seeking social support, and positive thinking) alongside workplace measures (including infection control and safety, staff support and recognition, and clear communication) were reported to be helpful. CONCLUSIONS: Psychological support for HCW in the current COVID-19 pandemic and future outbreaks should focus on both individual (eg, psychoeducation on possible psychological responses, self-care) and institutional (eg, clear communication, providing access to resources for help, recognition of efforts of HCW) measures.

Increase in prevalence of current mental disorders in the context of COVID-19: analysis of repeated nationwide cross-sectional surveys.

AIMS: The United Nations warned of COVID-19-related mental health crisis; however, it is unknown whether there is an increase in the prevalence of mental disorders as existing studies lack a reliable baseline analysis or they did not use a diagnostic measure. We aimed to analyse trends in the prevalence of mental disorders prior to and during the COVID-19 pandemic. METHODS: We analysed data from repeated cross-sectional surveys on a representative sample of non-institutionalised Czech adults (18+ years) from both November 2017 (n = 3306; 54% females) and May 2020 (n = 3021; 52% females). We used Mini International Neuropsychiatric Interview (MINI) as the main screening instrument. We calculated descriptive statistics and compared the prevalence of current mood and anxiety disorders, suicide risk and alcohol-related disorders at baseline and right after the first peak of COVID-19 when related lockdown was still in place in CZ. In addition, using logistic regression, we assessed the association between COVID-19-related worries and the presence of mental disorders. RESULTS: The prevalence of those experiencing symptoms of at least one current mental disorder rose from a baseline of 20.02 (95% CI = 18.64; 21.39) in 2017 to 29.63 (95% CI = 27.9; 31.37) in 2020 during the COVID-19 pandemic. The prevalence of both major depressive disorder (3.96, 95% CI = 3.28; 4.62 v. 11.77, 95% CI = 10.56; 12.99); and suicide risk (3.88, 95% CI = 3.21; 4.52 v. 11.88, 95% CI = 10.64; 13.07) tripled and current anxiety disorders almost doubled (7.79, 95% CI = 6.87; 8.7 v. 12.84, 95% CI = 11.6; 14.05). The prevalence of alcohol use disorders in 2020 was approximately the same as in 2017 (10.84, 95% CI = 9.78; 11.89 v. 9.88, 95% CI = 8.74; 10.98); however, there was a significant increase in weekly binge drinking behaviours (4.07% v. 6.39%). Strong worries about both, health or economic consequences of COVID-19, were associated with an increased odds of having a mental disorder (1.63, 95% CI = 1.4; 1.89 and 1.42, 95% CI = 1.23; 1.63 respectively). CONCLUSIONS: This study provides evidence matching concerns that COVID-19-related mental health problems pose a major threat to populations, particularly considering the barriers in service provision posed during lockdown. This finding emphasises an urgent need to scale up mental health promotion and prevention globally.

Mental Health of Medical Staff During the Coronavirus Disease 2019 Pandemic: A Systematic Review and Meta-Analysis.

OBJECTIVE: This study aimed to quantify the prevalence of the adverse mental health outcomes in medical staff working in the hospital settings during the coronavirus disease 2019 (COVID-19) pandemic and explore the relative distribution of anxiety and depressive symptoms. METHODS: PubMed, EMBASE, China National Knowledge Infrastructure, WANFANG DATA, and VIP Database for Chinese Technical Periodicals were searched for articles published from January 1, 2019, to April 19, 2020. The prevalence estimates of adverse mental health symptoms in medical staff were pooled using the random-effects model. RESULTS: A total of 35 articles and data of 25,343 medical staff were used in the final analysis. The pooled prevalence estimates in medical staff during the COVID-19 pandemic were as follows (ordered from high to low): fear-related symptoms, 67% (95% confidence interval [CI] = 61%-73%); high levels of perceived stress, 56% (95% CI = 32%-79%), anxiety symptoms, 41% (95% CI = 35%-47%); insomnia, 41% (95% CI = 33%-50%); posttraumatic stress disorder symptoms, 38% (95% CI = 34%-43%); depressive symptoms, 27% (95% CI = 20%-34%); and somatic symptoms, 16% (95% CI = 3%-36%). The subgroup analysis revealed that the prevalence estimates of fear-related symptoms were consistently high. CONCLUSIONS: Medical staff during the COVID-19 epidemic have a high prevalence of adverse mental health symptoms. Data-based strategies are needed to optimize mental health of medical staff and other health care professionals during times of high demand such as the COVID-19 and other epidemics.PROSPERO Registration: CRD42020182433.

Mental Health and Psychological Responses During the Coronavirus Disease 2019 Epidemic: A Comparison Between Wuhan and Other Areas in China.

OBJECTIVE: This study aimed to compare the mental health and psychological responses in Wuhan, a severely affected area, and other areas of China during the coronavirus disease 2019 (COVID-19) epidemic. METHODS: This cross-sectional study was conducted on February 10-20, 2020. A set of online questionnaires was used to measure mental health and responses. A total of 1397 participants from Wuhan (age, 36.4 ± 10.7 years; male, 36.1%) and 2794 age- and sex-matched participants from other areas of China (age, 35.9 ± 9.9 years; male, 39.0%) were recruited. RESULTS: Compared with their counterparts, participants from Wuhan had a significantly higher prevalence of any mental health problems (46.6% versus 32.2%; adjusted odds ratio [OR] = 1.89, 95% confidence interval [CI] = 1.65-2.17), anxiety (15.2% versus 6.2%; adjusted OR = 2.65, 95% CI = 2.14-3.29), depression (18.3% versus 9.7%; adjusted OR = 2.11, 95% CI = 1.74-2.54), suicidal ideation (10.5% versus 7.1%; adjusted OR = 1.60, 95% CI = 1.28-2.02), and insomnia (38.6% versus 27.6%; adjusted OR = 1.70, 95% CI = 1.48-1.96). Participants from Wuhan had a slightly higher rate of help-seeking behavior (7.1% versus 4.2%; adjusted OR = 1.76, 95% CI = 1.12-2.77) but similar rate of treatment (3.5% versus 2.7%; adjusted OR = 1.23, 95% CI = 0.68-2.24) for mental problems than did their counterparts. In addition, compared with their counterparts, participants from Wuhan gave higher proportions of responses regarding "fearful" (52% versus 36%, p < .001), "discrimination against COVID-19 cases" (64% versus 58%, p = .006), "strictly comply with preventive behaviors" (98.7% versus 96%, p = .003), and "fewer living and medical supplies" (<2 weeks: 62% versus 57%, p = .015). CONCLUSIONS: The COVID-19 epidemic has raised enormous challenges regarding public mental health and psychological responses, especially in the highly affected Wuhan area. The present findings provide important information for developing appropriate strategies for the prevention and management of mental health problems during COVID-19 and other epidemics.

Bridging Knowledge Gaps in the Diagnosis and Management of Neuropsychiatric Sequelae of COVID-19.

Importance: Neuropsychiatric symptoms have been reported as a prominent feature of postacute sequelae of COVID-19 (PASC), with common symptoms that include cognitive impairment, sleep difficulties, depression, posttraumatic stress, and substance use disorders. A primary challenge of parsing PASC epidemiology and pathophysiology is the lack of a standard definition of the syndrome, and little is known regarding mechanisms of neuropsychiatric PASC. Observations: Rates of symptom prevalence vary, but at least 1 PASC neuropsychiatric symptom has been reported in as many as 90% of patients 6 months after COVID-19 hospitalization and in approximately 25% of nonhospitalized adults with COVID-19. Mechanisms of neuropsychiatric sequelae of COVID-19 are still being elucidated. They may include static brain injury accrued during acute COVID-19, neurodegeneration triggered by secondary effects of acute COVID-19, autoimmune mechanisms with chronic inflammation, viral persistence in tissue reservoirs, or reactivation of other latent viruses. Despite rapidly emerging data, many gaps in knowledge persist related to the variable definitions of PASC, lack of standardized phenotyping or biomarkers, variability in virus genotypes, ascertainment biases, and limited accounting for social determinants of health and pandemic-related stressors. Conclusions and Relevance: Growing data support a high prevalence of PASC neuropsychiatric symptoms, but the current literature is heterogeneous with variable assessments of critical epidemiological factors. By enrolling large patient samples and conducting state-of-the-art assessments, the Researching COVID to Enhance Recovery (RECOVER), a multicenter research initiative funded by the National Institutes of Health, will help clarify PASC epidemiology, pathophysiology, and mechanisms of injury, as well as identify targets for therapeutic intervention.

Are we facing a crashing wave of neuropsychiatric sequelae of COVID-19? Neuropsychiatric symptoms and potential immunologic mechanisms.

The coronavirus disease 19 (COVID-19) pandemic is a significant psychological stressor in addition to its tremendous impact on every facet of individuals' lives and organizations in virtually all social and economic sectors worldwide. Fear of illness and uncertainty about the future precipitate anxiety- and stress-related disorders, and several groups have rightfully called for the creation and dissemination of robust mental health screening and treatment programs for the general public and front-line healthcare workers. However, in addition to pandemic-associated psychological distress, the direct effects of the virus itself (several acute respiratory syndrome coronavirus; SARS-CoV-2), and the subsequent host immunologic response, on the human central nervous system (CNS) and related outcomes are unknown. We discuss currently available evidence of COVID-19 related neuropsychiatric sequelae while drawing parallels to past viral pandemic-related outcomes. Past pandemics have demonstrated that diverse types of neuropsychiatric symptoms, such as encephalopathy, mood changes, psychosis, neuromuscular dysfunction, or demyelinating processes, may accompany acute viral infection, or may follow infection by weeks, months, or longer in recovered patients. The potential mechanisms are also discussed, including viral and immunological underpinnings. Therefore, prospective neuropsychiatric monitoring of individuals exposed to SARS-CoV-2 at various points in the life course, as well as their neuroimmune status, are needed to fully understand the long-term impact of COVID-19, and to establish a framework for integrating psychoneuroimmunology into epidemiologic studies of pandemics.
