Female reproductive health impacts of Long COVID and associated illnesses including ME/CFS, POTS, and connective tissue disorders: a literature review.

Long COVID disproportionately affects premenopausal women, but relatively few studies have examined Long COVID's impact on female reproductive health. We conduct a review of the literature documenting the female reproductive health impacts of Long COVID which may include disruptions to the menstrual cycle, gonadal function, ovarian sufficiency, menopause, and fertility, as well as symptom exacerbation around menstruation. Given limited research, we also review the reproductive health impacts of overlapping and associated illnesses including myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), postural orthostatic tachycardia syndrome (POTS), connective tissue disorders like Ehlers-Danlos syndrome (EDS), and endometriosis, as these illnesses may help to elucidate reproductive health conditions in Long COVID. These associated illnesses, whose patients are 70%-80% women, have increased rates of dysmenorrhea, amenorrhea, oligomenorrhea, dyspareunia, endometriosis, infertility, vulvodynia, intermenstrual bleeding, ovarian cysts, uterine fibroids and bleeding, pelvic congestion syndrome, gynecological surgeries, and adverse pregnancy complications such as preeclampsia, maternal mortality, and premature birth. Additionally, in Long COVID and associated illnesses, symptoms can be impacted by the menstrual cycle, pregnancy, and menopause. We propose priorities for future research and reproductive healthcare in Long COVID based on a review of the literature. These include screening Long COVID patients for comorbid and associated conditions; studying the impacts of the menstrual cycle, pregnancy, and menopause on symptoms and illness progression; uncovering the role of sex differences and sex hormones in Long COVID and associated illnesses; and addressing historical research and healthcare inequities that have contributed to detrimental knowledge gaps for this patient population.

Diagnostic value of blood oxygen saturation and C-Reactive Protein (CRP) in Predicting Lung Sequels in COVID-19 infected patients admitted to hospital: A 12-week cohort study

Background: Evidence of COVID-19 respiratory sequels is restricted and predisposing factors are not well studied more than two years passing pandemic. This study followed COVID-19 patients 12 weeks after discharge from hospital for respiratory sequels. Material(s) and Method(s): This was a prospective study on discharged COVID-19 patients in 2021, in Jahrom, Iran. Exposure was COVID-19 clinical features at hospitalization, including symptoms and physical examination and laboratory findings, and primary endpoint was 12-week lung sequel, being evaluated by a chest CT scan. Demographics and previous medical history were considered covariates. SPO2and CRP 6-week changes were followed as an early tool for prediction of 12-week lung sequel. Result(s): Totally, 383 participants (17 had sequels) with mean age of 57.43 18.03 years old (50.13% male) completed 12-week study follow-ups. Ninety-one (23.8%) subjects had an ICU admission history. SPO2% in 6th week was statistically significantly associated with a higher rate of 12-week sequelae (p<0.001). Also, patients having CT scan scores between 40% to 50% (p=0.012) and higher than 50% (p=0.040) had higher chance of experiencing lung sequelae than patients with CT scan score of below 40%, as well as having ICU admission history and lower SPO2% at 6th week of discharge. There was a statistically significant increasing trend of SPO2% (P<0.001) and a statistically significant decreasing trend of CRP levels (P<0.001), overall. SPO2% increase after 6 weeks was lower in participants with lung sequels than fully improved ones (P=0.002) and as well as total 12-week change in SPO2% (P=0.001). CRP changes in none of evaluated periods were different among study groups (P>0.05). Conclusion(s): Our results were in favor of closely following SPO2levels after patient discharge, while CRP assessment seems not helpful based on our results [GMJ.2023;12:e2695].Copyright © 2023 Shiraz University of Medical Sciences.

Elevated circulating monocytes and monocyte activation in COVID-19 convalescent individuals.

Background: Monocytes and macrophages play a pivotal role in inflammation during acute SARS-CoV-2 infection. However, their contribution to the development of post-acute sequelae of SARS-CoV-2 infection (PASC) are not fully elucidated. Methods: A cross-sectional study was conducted comparing plasma cytokine and monocyte levels among three groups: participants with pulmonary PASC (PPASC) with a reduced predicted diffusing capacity for carbon monoxide [DLCOc, <80%; (PG)]; fully recovered from SARS-CoV-2 with no residual symptoms (recovered group, RG); and negative for SARS-CoV-2 (negative group, NG). The expressions of cytokines were measured in plasma of study cohort by Luminex assay. The percentages and numbers of monocyte subsets (classical, intermediate, and non-classical monocytes) and monocyte activation (defined by CD169 expression) were analyzed using flow cytometry analysis of peripheral blood mononuclear cells. Results: Plasma IL-1Ra levels were elevated but FGF levels were reduced in PG compared to NG. Circulating monocytes and three subsets were significantly higher in PG and RG compared to NG. PG and RG exhibited higher levels of CD169+ monocyte counts and higher CD169 expression was detected in intermediate and non-classical monocytes from RG and PG than that found in NG. Further correlation analysis with CD169+ monocyte subsets revealed that CD169+ intermediate monocytes negatively correlated with DLCOc%, and CD169+ non-classical monocytes positively correlated with IL-1α, IL-1ß, MIP-1α, Eotaxin, and IFN-γ. Conclusion: This study present evidence that COVID convalescents exhibit monocyte alteration beyond the acute COVID-19 infection period even in convalescents with no residual symptoms. Further, the results suggest that monocyte alteration and increased activated monocyte subsets may impact pulmonary function in COVID-19 convalescents. This observation will aid in understanding the immunopathologic feature of pulmonary PASC development, resolution, and subsequent therapeutic interventions.

Long COVID Incidence in a Large US Ambulatory Electronic Health Record System.

Estimates of the prevalence of long COVID vary widely. This retrospective cohort study describes the incidence of long COVID symptoms 12-20 weeks post-diagnosis in a US ambulatory care setting and identifies potential risk factors. We identified patients with and without a diagnosis of or positive test for COVID-19 between 1/1/2020 and 3/13/2022 in the Veradigm EHR database. We captured patient demographics, clinical characteristics, and COVID-19 comorbidities in the 12-month baseline period. We compared long COVID symptoms between matched cases and controls 12-20 weeks post-index (COVID-19 diagnosis date [cases] or median visit date [controls]). Multivariable logistic regression was used to examine associations between baseline COVID-19 comorbidities and long COVID symptoms. Among 916,894 patients with COVID-19, 14.8% had at least one long COVID symptom in the 12-20 weeks post-index compared to 2.9% of patients without documented COVID-19. Commonly reported symptoms were joint stiffness (4.5%), cough (3.0%), and fatigue (2.7%). Among patients with COVID-19, the adjusted odds of long COVID symptoms were significantly higher among patients with a baseline COVID-19 comorbidity (odds ratio: 1.91 [95% confidence interval: 1.88-1.95]). In particular, prior diagnosis of cognitive disorders, transient ischemic attack, hypertension, and obesity were associated with higher odds of long COVID symptoms.

Physiotherapy in Neurological Conditions: AB No: 179: Is Assessment of Balance Important in SARS �CoV-2 Survivors before discharge?

Purpose: To emphasize the importance of Balance assessment as integral part of SARS SARS-CoV-2 rehabilitation so that a ‘'future pandemic” of falls can be prevented. Relevance: Balance assessment in acute-care setting can help prevent falls and subsequent consequences complication during the course of rehabilitation. Participants: SARS –CoV-2 recovered survivors (n=130), who were admitted for a minimum of 7 days and on O2 support. Methods: Institutional Ethic committee approval was obtained. Patients admitted to the hospital with a confirmed diagnosis of SARS-CoV-2 who were on O2 support and minimum duration of hospital stay>7 days were recruited for the study. Balance impairment was assessed using Tinette POMA and the obtained data was analyzed. Analysis: DescriptiveResults: A total of (n=130) patients were identified, 54 patients were at risk of falls, 36 were at high risk and 18 were at moderate risk of fall. In the results, there is a significant balance impairment in O2 dependent SARS-CoV-2 survivors. Conclusion: Balance Assessment should be included in SARS-CoV-2 survivors so that a tailored exercise prescription can be formulated that will not only enhance their functional activities but also reduce the risk of falls and may prevent further complications. Implications: Balance Assessment will help to identify the patient who are at high risk of falls and effective rehabilitation can be planned. Early detection of fall risk through balance assessment paves way for targeted, integrated intervention through a tailored exercise program based on the findings thus, reducing the burden of the patient and healthcare system in general.

Viruses and amyloids - a vicious liaison.

The crosstalk between viral infections, amyloid formation and neurodegeneration has been discussed with varying intensity since the last century. Several viral proteins are known to be amyloidogenic. Post-acute sequalae (PAS) of viral infections is known for several viruses. SARS-CoV-2 and COVID-19 implicate connections between amyloid formation and severe outcomes in the acute infection, PAS and neurodegenerative diseases. Is the amyloid connection causation or just correlation? In this review we highlight several aspects where amyloids and viruses meet. The evolutionary driving forces that dictate protein amyloid formation propensity are different for viruses compared to prokaryotes and eukaryotes, while posttranslational endoproteolysis appears to be a common mechanism leading up to amyloid formation for both viral and human proteins. Not only do human and viral proteins form amyloid irrespective of each other but there are also several examples of co-operativity between amyloids, viruses and the inter-, and intra-host spread of the respective entity. Abnormal blood clotting in severe and long COVID and as a side effect in some vaccine recipients has been connected to amyloid formation of both the human fibrin and the viral Spike-protein. We conclude that there are many intersects between viruses and amyloids and, consequently, amyloid and virus research need to join forces here. We emphasize the need to accelerate development and implementation in clinical practice of antiviral drugs to preclude PAS and downstream neurological damage. There is also an ample need for retake on suitable antigen targets for the further development of next generation of vaccines against the current and coming pandemics.

Low Prevalence of Interferon-α Autoantibodies in People Experiencing Long COVID Symptoms.

Interferon (IFN)-specific autoantibodies have been implicated in severe COVID-19 and have been proposed as a potential driver of the persistent symptoms characterizing Long COVID, a type of post-acute sequelae of SARS-CoV-2 infection (PASC). We report than only two of 215 SARS-CoV-2 convalescent participants tested over 394 timepoints, including 121 people experiencing Long COVID symptoms, had detectable IFN-α2 antibodies. Both had been hospitalized during the acute phase of the infection. These data suggest that persistent anti-IFN antibodies, although a potential driver of severe COVID-19, are unlikely to contribute to Long COVID symptoms in the post-acute phase of the infection.

Association of Lung Fibrotic Changes and Cardiological Dysfunction with Comorbidities in Long COVID-19 Cohort.

Background. Long COVID-19 symptoms appeared in many COVID-19 survivors. However, the prevalence and symptoms associated with long COVID-19 and its comorbidities have not been established. Methods. In total, 312 patients with long COVID-19 from 21 primary care centers were included in the study. At the six-month follow-up, their lung function was assessed by computerized tomography (CT) and spirometry, whereas cardiac function was assessed by elec-trocardiogram (ECG), Holter ECG, echocardiography, 24 h blood pressure monitoring, and a six-minute walk test (6MWT). Results. Of the 312 persons investigated, significantly higher sys-tolic and diastolic blood pressure, left ventricular hypertrophy, and elevated NT-proBNP were revealed in participants with hypertension or type 2 diabetes. Left ventricular diastolic dysfunc-tion was more frequently present in patients with hypertension. The most common registered CT abnormalities were fibrotic changes (83, 36.6%) and mediastinal lymphadenopathy (23, 10.1%). Among the tested biochemical parameters, three associations were found in long COVID-19 patients with hypertension but not diabetes: increased hemoglobin, fibrinogen, and ferritin. Nine patients had persisting IgM antibodies to SARS-CoV-2. Conclusions. We demon-strated a strong association between signs of cardiac dysfunction and lung fibrotic changes with comorbidities in a cohort of long COVID-19 subjects.

Comparative analysis of long-term self-reported COVID-19 symptoms among pregnant women.

BACKGROUND: The negative effects of COVID-19 infections during pregnancy have been amply described, however, the persistent sequels of this infection have not been explored so far. OBJECTIVE: The aim of this study was to describe persisting symptoms after COVID-19 infection in pregnant and non-pregnant women in Ecuador. METHODS: A cross-sectional analysis based on an online, self-reporting questionnaire was conducted in Ecuador from April to July 2022. Participants were invited by social media, radio, and TV to voluntarily participate in our study. A total of 457 surveys were included in this study. We compared risk factor variables and long-term persisting symptoms of pregnant and non-pregnant women in Ecuador. RESULTS: Overall, 247 (54.1 %) responders claimed to have long-term symptoms after SARS-CoV-2 infection. Most of these symptoms were reported by non-pregnant women (94.0 %). The most common Long-COVID symptoms in pregnant women were fatigue (10.6 %), hair loss (9.6 %), and difficulty concentrating (6.2 %). We found that pregnant women who smoked had a higher risk of suffering fatigue. CONCLUSIONS: The most frequent Long-COVID symptoms in pregnant women were fatigue, hair loss, and difficulty concentrating. Apparently, the patterns of presentation of long-term sequelae of SARS-CoV-2 infection in pregnant women do not differ significantly from reports available from studies in the general population.

Phenotypic alteration of low-density granulocytes in people with pulmonary post-acute sequalae of SARS-CoV-2 infection.

Background: Low-density granulocytes (LDGs) are a distinct subset of neutrophils whose increased abundance is associated with the severity of COVID-19. However, the long-term effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on LDG levels and phenotypic alteration remain unexplored. Methods: Using participants naïve to SARS-CoV-2 (NP), infected with SARS-CoV-2 with no residual symptoms (NRS), and infected with SARS-CoV-2 with chronic pulmonary symptoms (PPASC), we compared LDG levels and their phenotype by measuring the expression of markers for activation, maturation, and neutrophil extracellular trap (NET) formation using flow cytometry. Results: The number of LDGs was elevated in PPASC compared to NP. Individuals infected with SARS-CoV-2 (NRS and PPASC) demonstrated increased CD10+ and CD16hi subset counts of LDGs compared to NP group. Further characterization of LDGs demonstrated that LDGs from COVID-19 convalescents (PPASC and NRS) displayed increased markers of NET forming ability and aggregation with platelets compared to LDGs from NP, but no differences were observed between PPASC and NRS. Conclusions: Our data from a small cohort study demonstrates that mature neutrophils with a heightened activation phenotype remain in circulation long after initial SARS-CoV-2 infection. Persistent elevation of markers for neutrophil activation and NET formation on LDGs, as well as an enhanced proclivity for platelet-neutrophil aggregation (PNA) formation in COVID-19 convalescent individuals may be associated with PPASC prognosis and development.

Persistent symptoms among post-COVID-19 survivors: A systematic review and meta-analysis.

BACKGROUND: Single studies support the presence of several post-COVID-19 symptoms; however, there is no evidence for the synthesis of symptoms. OBJECTIVE: We attempt to provide an overview of the persistent symptoms that post-COVID-19 patients encounter, as well as the duration of these symptoms to help them plan their rehabilitation. DESIGN: Systematic review and meta-analysis. PARTICIPANTS: A total of 16 studies involving 8756 patients post-COVID-19 were included. METHODS: The CINAHL, PubMed, EMBASE, Scopus, and Web of Science databases were searched from 2019 to August 2021. Observational studies that reported data on post-COVID-19 symptoms were included. The methodological quality of the studies was assessed using the Joanna Briggs Institute Critical Appraisal for Observational Studies. We included medium- to high-quality studies. We used a random-effects model for the meta-analytical pooled prevalence of each post-COVID-19 symptom, and I2 statistics for heterogeneity. RESULTS: From the 2481 studies identified, 16 met the inclusion criteria. The sample included 7623 hospitalised and 1133 non-hospitalised patients. We found the most prevalent symptoms were fatigue and dyspnea with a pooled prevalence ranging from 42% (27%-58%). Other post-COVID-19 symptoms included sleep disturbance 28% (14%-45%), cough 25% (10%-44%), anosmia/ageusia 24% (7%-47%), fever 21% (4%-47%), myalgia 17% (2%-41%), chest pain 11% (5%-20%), and headache 9% (2%-20%). In addition to physical symptoms, anxiety/depression was also prevalent 27% (8%-53%). CONCLUSIONS: Fatigue and dyspnea were the most prevalent post-COVID-19 symptoms and experienced up to 12 months. RELEVANCE TO CLINICAL PRACTICE: Multiple persistent symptoms are still experienced until 12 months of post-Covid 19. This meta-analysis should provide some awareness to nurses to highlights the unmet healthcare needs of post-COVID-19 patients. Long-term monitoring for the evaluation and treatment of symptoms and conditions and rehabilitation programs should be conducted.

A Scoping Review on Long COVID-19: Physiological and Psychological Symptoms Post-Acute, Long-Post and Persistent Post COVID-19.

Background: The identification of persistent symptoms of chronic/long COVID-19 is crucial in understanding the management of long haulers of post COVID-19. Methods: Pub Med (Medline) database was scoped for original articles based on a search strategy related to the objectives. The selected articles post-screening were analyzed for variables relating to chronic/long COVID-19. Results were analyzed using descriptive statistics. Results: A total of 33 studies were reviewed. A total of 60% of the studies were observational studies and most of them were from high income countries. Almost half of the studies were in phase 3 of post-COVID-19, i.e., symptoms lasting >24 weeks. Among the physiological and psychological symptoms studied, fatigue, dyspnea, cough, headache, memory loss, depression, brain fog and lack of concentration were found to be the most frequently reported symptoms. Excessive sleep, constipation and neuropathic pain were among the least reported symptoms. Prior hospitalization, the female gender was found to be a risk factor. Limitations were reported by all studies. Conclusions: The major physiological and psychological symptoms of long COVID-19 have been explained with risk factors and its impact on patients' lifestyles. The findings of this review hope to facilitate clinicians to draw conclusions to manage the long-term effects of post/chronic COVID-19.

Brain Fog and Fatigue following COVID-19 Infection: An Exploratory Study of Patient Experiences of Long COVID.

Post-acute sequelae of SARS-CoV-2 (PASC) is a poorly understood condition with significant impact on quality of life. We aimed to better understand the lived experiences of patients with PASC, focusing on the impact of cognitive complaints ("brain fog") and fatigue on (1) daily activities, (2) work/employment, and (3) interpersonal relationships. We conducted semi-structured qualitative interviews with 15 patients of a Midwestern academic hospital's post-COVID-19 clinic. We audio-recorded, transcribed, and analyzed interviews thematically using a combined deductive-inductive approach and collected participants' characteristics from chart review. Participants frequently used descriptive and metaphorical language to describe symptoms that were relapsing-remitting and unpredictable. Fatigue and brain fog affected all domains and identified subthemes included symptoms' synergistic effects, difficulty with multitasking, lack of support, poor self-perception, and fear of loss of income and employment. Personal relationships were affected with change of responsibilities, difficulty parenting, social isolation, and guilt due to the burdens placed on family. Furthermore, underlying social stigma contributed to negative emotions, which significantly affected emotional and mental health. Our findings highlight PASC's negative impact on patients' daily lives. Providers can better support COVID-19 survivors during their recovery by identifying their needs in a sensitive and timely manner.

Long COVID at Different Altitudes: A Countrywide Epidemiological Analysis.

BACKGROUND: Several reports from around the world have reported that some patients who have recovered from COVID-19 have experienced a range of persistent or new clinical symptoms after a SARS-CoV-2 infection. These symptoms can last from weeks to months, impacting everyday functioning to a significant number of patients. METHODS: A cross-sectional analysis based on an online, self-reporting questionnaire was conducted in Ecuador from April to July 2022. Participants were invited by social media, radio, and TV to voluntarily participate in our study. A total of 2103 surveys were included in this study. We compared socio-demographic variables and long-term persisting symptoms at low (<2500 m) and high altitude (>2500 m). RESULTS: Overall, 1100 (52.3%) responders claimed to have Long-COVID symptoms after SARS-CoV-2 infection. Most of these were reported by women (64.0%); the most affected group was young adults between 21 to 40 years (68.5%), and most long-haulers were mestizos (91.6%). We found that high altitude residents were more likely to report persisting symptoms (71.7%) versus those living at lower altitudes (29.3%). The most common symptoms were fatigue or tiredness (8.4%), hair loss (5.1%) and difficulty concentrating (5.0%). The highest proportion of symptoms was observed in the group that received less than 2 doses. CONCLUSIONS: This is the first study describing post-COVID symptoms' persistence in low and high-altitude residents. Our findings demonstrate that women, especially those aging between 21-40, are more likely to describe Long-COVID. We also found that living at a high altitude was associated with higher reports of mood changes, tachycardia, decreased libido, insomnia, and palpitations compared to lowlanders. Finally, we found a greater risk to report Long-COVID symptoms among women, those with previous comorbidities and those who had a severer acute SARS-CoV-2 infection.

A Mixed-Methods Evaluation of a Virtual Rehabilitation Program for Self-Management in Post-COVID-19 Syndrome (Long COVID).

Long COVID (LC) symptoms can be long standing, diverse and debilitating; comprehensive multidisciplinary rehabilitation programs are required to address this. A 10-week LC Virtual Rehabilitation Program (VRP) was developed to provide early education and self-management techniques to address the main symptoms of LC and was delivered to a group of persons with Long COVID (PwLC) online, facilitated by members of the multi-disciplinary rehabilitation team. This paper describes an evaluation of this VRP. Questionnaires completed by Healthcare Professionals (HCP) delivering the VRP were thematically analyzed to gain a priori themes and design semi-structured telephone interview questions for PwLC. Template analysis (TA) was used to analyze interview data. Routinely collected patient demographics and service data were also examined. Seventeen HCP survey responses were obtained and 38 PwLC telephone questionnaires were completed. The HCP interviews generated three a priori themes (1. Attendance and Availability, 2. Content, 3. Use of Digital Technology). TA was applied and three further themes emerged from the combined HCP and PwLC responses (4. Group Dynamics, 5. Individual Factors, 6. Internal Change). Key outcomes demonstrated that: the VRP was highly valued; digital delivery enabled self-management; barriers to attendance included work/life balance, use of technology, health inequalities; and LC was poorly understood by employers. Recommendations are provided for the design of VRPs for LC.

Changes in Lung Diffusion Capacity after SARS-CoV-2 Infections in Highly Trained Athletes

Objectives: By now, many long-term symptoms after COVID-19 are described, mostly concerning hospitalized patients. Our aim was to investigate the long-term effect of COVID-19 on the lung function with focus on the diffusion capacity of athletes. › Methods: 99 athletes (34.17±11.94 years, 56% female) after CO VID-19 and 36 athletes (25.80±6.70 years, 65% female) without COVID-19 as controls were included. Symptom severity and lung function were assessed. Lung function of controls were compared with athletes after COVID-19 and changes in patients with dyspnea (during infection and at time of appointment) and changes over time between infection and examination on lung function were examined. › Results: Exertional dyspnea during the infection was reported by 51% of athletes after COVID-19, respectively 27% at the time of examination (158±137 days after infection). 30% of athletes after COVID-19 showed a reduced Diffusion Capacity of the Lungs for Carbon Monoxide (DLCO <80% of the predicted value). Athletes after COVID-19 showed a significant reduced forced vital capacity (p<0.01) and forced expiratory volume at 1s (p<0.01) compared to controls. Dyspnea during infection was associated with a significant reduction in DLCO (p<0.05). There was no significant difference in lung function parameters depending on dyspnea at examination or depending on the duration between infection and examination. › Conclusion: In athletes after COVID-19-Infection, static and dynamic lung volumes seem to be slightly reduced. Furthermore, athletes reporting dyspnea have lower than predicted DLCO. Factors could be reduced alveolar membrane function and lung perfusion. In the follow-up of athletes with dyspnea during infection, evaluation of diffusion capacity seems to be important. © 2022, Dynamic Media Sales Verlag. All rights reserved.

Prevalence of depression and its associated factors among patients with confirmed COVID-19 in Makkah, Saudi Arabia.

Background: In early December 2019, a cluster of acute pneumonia of viral etiology had been identified in Wuhan, China. Later on, it has been named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing a worldwide pandemic. This pandemic triggered unprecedented health-related psychiatric sequalae. We aim in this study to evaluate the prevalence of depression and its associated factors among confirmed patients with COVID-19. Methodology: This is a cross-sectional study, we included adult patients more than 18 years old who have been diagnosed with PCR-confirmed COVID-19 and managed in a hospital, home, or hotel. A self-administered online questionnaire based on Patient Health Questionnaire (PHQ-9) Quick Depression Assessment questionnaire was used. Results: A total of 143 subjects completed the PHQ-9 questionnaire. The prevalence of moderate to severe depression was 34%. Prevalence of depression was positively associated with the female gender (p-value = 0.013). Location of COVID-19 management and financial status did not affect the prevalence of depression. Conclusion: The prevalence of depression among patients with COVID-19 is high, which underscores the importance of active screening and management of depression in this population.

Real-world use of the Breathing Pattern Assessment Tool in assessment of breathlessness post-COVID-19.

INTRODUCTION: Breathing pattern disorders (BPDs) are a common cause of chronic breathlessness, including after acute respiratory illnesses such as COVID pneumonia. BPD is however underdiagnosed, partly as a result of difficulty in clinically assessing breathing pattern. The Breathing Pattern Assessment Tool (BPAT) has been validated for use in diagnosing BPD in patients with asthma but to date has not been validated in other diseases. METHODS: Patients undergoing face-to-face review in a post-COVID clinic were assessed by a respiratory physician and specialist respiratory physiotherapist. Assessment included a Dyspnoea-12 (D12) questionnaire to assess breathlessness, physiotherapist assessment of breathing pattern including manual assessment of respiratory motion, and BPAT assessment. The sensitivity and specificity of BPAT for diagnosis of BPD in post-COVID patients was assessed. RESULTS: BPAT had a sensitivity of 89.5% and specificity of 78.3% for diagnosing BPD in post-COVID breathlessness. Patients with a BPAT score above the diagnostic cut-off had higher levels of breathlessness than those with lower BPAT scores (D12 score mean average 19.4 vs 13.2). CONCLUSION: BPAT has high sensitivity and moderate specificity for BPD in patients with long COVID. This would support its use as a screening test in clinic, and as a diagnostic tool for large cohort studies.

Long COVID and neuropsychiatric manifestations (Review).

There is accumulating evidence in the literature indicating that a number of patients with coronavirus disease 2019 (COVID-19) may experience a range of neuropsychiatric symptoms, persisting or even presenting following the resolution of acute COVID-19. Among the neuropsychiatric manifestations more frequently associated with 'long COVID' are depression, anxiety, post-traumatic stress disorder, sleep disturbances, fatigue and cognitive deficits, that can potentially be debilitating and negatively affect patients' wellbeing, albeit in the majority of cases symptoms tend to improve over time. Despite variations in results obtained from studies using different methodological approaches to define 'long COVID' syndrome, the most widely accepted factors associated with a higher risk of developing neuropsychiatric manifestations include the severity of foregoing COVID-19, the female sex, the presence of comorbidities, a history of mental health disease and an elevation in the levels of inflammatory markers, albeit further research is required to establish causal associations. To date, the pathophysiological mechanisms implicated in neuropsychiatric manifestations of 'long COVID' remain only partially elucidated, while the role of the indirect effects of the COVID-19 pandemic, such as social isolation and uncertainty concerning social, financial and health recovery post-COVID, have also been highlighted. Given the alarming effects of 'long-COVID', interdisciplinary cooperation for the early identification of patients who are at a high risk of persistent neuropsychiatric presentations, beyond COVID-19 recovery, is crucial to ensure that appropriate integrated physical and mental health support is provided, with the aim of mitigating the risks of long-term disability at a societal and individual level.

Severe Post-COVID-19 dysautonomia: a case report.

BACKGROUND: The emergence of dysautonomia as a consequence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; or COVID-19) is becoming more prevalent. We have seen evidence in several post-COVID patients and in the literature of varying degrees of autonomic dysfunction. Symptoms, among others, include inappropriate tachycardia, sweating, anxiety, insomnia and blood pressure variability from the effects of excessive catecholamine, as well as cognitive impairment, fatigue, headaches and orthostatic intolerance from decreased brain perfusion. CASE PRESENTATION: We present a case of severe dysautonomia in a previously healthy 27-year-old runner. About five weeks after her initial mild COVID-19 infection, the patient began to develop weakness, which progressed into severe post-exertional fatigue, slowed cognition, headaches, blurred vision and generalized body aches. She also endorsed palpitations, especially when getting up from a seated or lying position as well as with mild exertion. She became reliant on her husband for help with her activities of daily living. Exam was significant for orthostasis; laboratory workup unremarkable. Over the following months, the patient's symptoms have improved slowly with fluid and sodium intake, compression stockings and participating in a graduated exercise program. CONCLUSIONS: Dysautonomia as a consequence of infection with COVID-19 is becoming increasingly discussed, especially as more patients recover from COVID-19. This is a case of a non-hospitalized patient with a mild initial presentation and significant, debilitating dysautonomia symptoms. More research on its pathophysiology, especially in relation to a precedent viral insult, as well as its treatment, is needed.
