Prevalence of Anxiety and Suicidal Ideation in Nurses Working in COVID-19 Wards Compared to Nurses From Other Hospital Wards During the Pandemic

Background and Objectives: Investigating the level of anxiety and suicidal thoughts in nurses during the COVID-19 pandemic can play an important role in helping them clinically to prevent the development of psychological symptoms in them. In this regard, this study aims to investigate the prevalence of anxiety and suicidal ideation in nurses working in COVID-19 wards compared to nurses from other departments. Methods: In this analytical cross-sectional study, participants were 347 nurses from two hospitals (Shahid Beheshti and Kamkar) in Qom, Iran in 2021. Nurses were divided into two groups working in COVID-19 and non-COVID wards. The data collection tools were a demographic form, Beck’s anxiety inventory, and the Beck scale for suicidal ideation. The data was analyzed in SPSS software version 22 using independent t-test or ANOVA for quantitative data and chi-square test for qualitative data. The significance level was set at 0.05. Results: Among participants, 139(40.1%) were in the COVID group and 208(59.9%) were in the non-COVID group. Nurses in the COVID group had significantly higher anxiety scores than nurses in the non-COVID group (P<0.001), but there was no significant difference between COVID and non-COVID groups in suicidal ideation (P=0.979). Conclusion: There is a high prevalence of anxiety among nurses working in COVID-19 wards compared to nurses from other wards. Therefore, it is recommended to use psychological treatments to reduce the anxiety and suicidal thoughts of these nurses during the COVID-19 pandemic.

Comparative analyses of post-infectious olfactory dysfunction between COVID-19 and non-COVID-19 cases

To identify the differences between COVID-19-associated and non-COVID-19-associated olfactory dysfunction (OD), we analyzed demographic and clinical characteristics based on the causative virus (COVID versus non-COVID groups) in patients with post-infectious olfactory dysfunction (PIOD) who underwent the olfactory questionnaire and olfactory function test. Out of 169 patients with PIOD, 99 were diagnosed with COVID-19 (COVID group), while 70 were not (non-COVID group). The COVID group was younger and had a higher percentage of male patients as well as patients with parosmia than the non-COVID group. In the initial olfactory function tests, the TDI, discrimination and identification scores were significantly higher in the COVID group than in the non-COVID group. TDI scores were significantly increased in patients with PIOD after treatment, regardless of the group. The threshold score was significantly increased by 1.38 in the COVID group while the identification score was significantly increased by 2.67 in the non-COVID group. Patients with COVID-19-associated OD were younger in age, tended to be male, had a higher incidence of parosmia, and had better initial olfactory function test results compared to those with non-COVID-19-associated OD. Following treatment, odor detection threshold improved in the COVID group, whereas odor identification improved in the non-COVID group.

COVID-19 is associated with cardiac structural and functional remodelling in healthy middle-aged and older individuals.

Coronavirus disease 2019 (COVID-19) was declared a global pandemic in 2019. It remains uncertain to what extent COVID-19 effects the heart in heathy individuals. To evaluate the effect of the COVID-19 on cardiac structure and function in middle-aged and older individuals. A single-centre prospective observational study enroled a total of 124 participants (84 with history of COVID-19 [COVID-19 group] and 40 without a history of COVID-19 [non-COVID group]). All participants underwent echocardiography with speckle tracking to assess cardiac structure and function at rest and during peak exercise. There were no differences in left and right ventricular diastolic function (p ≥ 0.05) between the COVID-19 and non-COVID-19 groups. Participants in COVID-19 group demonstrated higher left ventricular mass (130 ± 39.8 vs. 113 ± 27.2 g, p = 0.008) and relative wall thickness (0.38 ± 0.07 vs. 0.36 ± 0.13, p = 0.049). Left ventricular global longitudinal strain was reduced in the COVID-19 group at rest and at peak-exercise (rest: 18.3 ± 2.01 vs. 19.3 ± 1.53%, p = 0.004; peak exercise: 19.1 ± 2.20 vs. 21.0 ± 1.58%, p ≤ 0.001). However, no difference was seen in resting left ventricular ejection fraction (58 ± 2.89 vs. 59 ± 2.51%, p = 0.565) between groups. Right ventricular fractional area change was reduced in the COVID-19 group (p = 0.012). Cardiac structural and functional remodelling was observed in middle-aged and older otherwise healthy individuals with a history of COVID-19.

Assessing the impact of enhanced hygiene precautions during the COVID-19 pandemic on surgical site infection risk in abdominal surgeries

BackgroundA surgical site infection (SSI) is a postoperative infection that occurs at or near the surgical incision. SSIs significantly increase morbidity, mortality, length of hospital stay, and healthcare costs. The World Health Organization (WHO) has established hospital hygiene precaution guidelines for the prevention of SSIs, which were enhanced during the COVID-19 pandemic. The current study aims to explore the effect of the COVID-19 pandemic on SSI incidence among initially uninfected postoperative patients. We hypothesize that these enhanced precautions would reduce the incidence of SSIs.Materials and methodsA retrospective study comparing surgical outcomes before and during the pandemic. Patients who had abdominal surgery between June and December 2019 (Non-COVID-19) or between February and June 2020 (COVID-19) were included. The two groups were matched in a 1:1 ratio based on age, Sex, acuity (elective or emergent), surgical approach, and comorbidities. Electronic medical records were reviewed to identify SSIs and hospital readmissions within 30 days after surgery. Pearson's chi-square test and Fisher's exact test were used.ResultsData was collected and analyzed from 976 patients who had surgery before the COVID-19 pandemic (non-COVID group) and 377 patients who had surgery during the pandemic (COVID group). After matching, there were 377 patients in each group. In our study, we found 23 surgical site infections (SSIs) in both laparoscopic and open surgeries. The incidence of SSIs was significantly higher in the non-COVID period compared to the COVID period [17 cases (4.5%) vs. 6 cases (1.6%), respectively, p = 0.032], especially in non-COVID open surgeries. The incidence of SSIs in laparoscopic surgeries was also higher during the non-COVID period, but not statistically significant.ConclusionsEnhanced hygiene precautions during the COVID -19 pandemic may have reduced SSIs rates following abdominal surgery.

Extracorporeal membrane oxygenation support in adult patients: Comparing COVID-19- and non-COVID-19-associated respiratory failure.

Extracorporeal membrane oxygenation (ECMO) is a vital intervention for acute respiratory distress syndrome (ARDS), yet its efficacy with coronavirus disease 2019 (COVID-19) remains unknown. This study compared the long-term mortality rates of patients receiving ECMO for COVID-19 with those experiencing other respiratory disease-associated ARDS. This retrospective cohort study included adults with ARDS receiving ECMO for respiratory disease (COVID-19 and non-COVID-19) based on information collected from the National Health Insurance Service of South Korea from February 1, 2020, to December 31, 2021. The primary outcome was all-cause mortality at 6 months and 1 year post-ECMO initiation. Data from 3094 patients with COVID-19 (N = 1095) and non-COVID-19 respiratory disease-associated ARDS (N = 1999) who received ECMO support were analyzed. Despite a higher Charlson Comorbidity index in the non-COVID group, patients with COVID-19 had higher cumulative mortality rates at 6 months and 1 year post-ECMO initiation compared to those with non-COVID-19 respiratory diseases, after adjusting for confounders. Patients with COVID-19 also experienced longer intensive care unit stays, higher hospitalization costs, longer ECMO and mechanical ventilation durations, and lower intensity coverage. Patients with COVID-19 requiring ECMO showed higher mortality rates, possibly due to its distinct long-lasting and potentially fatal consequences compared to other respiratory illnesses.

Outcomes in COVID-19 Patients with Acute Cholangitis: A Single-Center Retrospective Analysis.

Background and Objectives: This study aimed to assess the impact of coronavirus disease 2019 (COVID-19) on patients with acute cholangitis (AC) by comparing outcomes, complications, and hospital stays in a tertiary Gastroenterology department. Materials and Methods: This retrospective observational cohort study was conducted in a tertiary gastroenterology department, collecting data from all AC and AC + COVID-19 patients between April 2020 and February 2022. Data included clinical and demographic information, COVID-19-specific details, acute cholangitis presentation, medical records, laboratory results, and interventions. AC was diagnosed using Tokyo Guidelines 2018 (TG18) criteria, with all patients undergoing bile culture sampling. Results: The study included 241 patients, 30 in the COVID group and 211 in the non-COVID group. The COVID group's mean age was significantly higher (74.3 vs. 67.3 years, p < 0.009). Abdominal pain was more common in the COVID group (90% vs. 70.6%, p < 0.025). Length of hospital stay was longer for COVID patients (13.5 vs. 7.9 days, p < 0.001). COVID patients had higher incidences of malignant causes of AC, with pancreatic cancer being the most common (30%). Pseudomonas spp. was significantly more prevalent in COVID patients (16.7% vs. 5.7%, p = 0.028). Conclusions: Our study results show that COVID-19 affected the duration of hospitalization for patients with AC. Furthermore, this study presents observations regarding the impact of COVID-19 on AC, revealing differences in microbial profiles.

Hospitalization outcome of patients with lung cancer with COVID-19 infection: NIS 2020 analysis.

212 Background: Lung cancer is the most commonly diagnosed cancer and the leading cause of cancer-related deaths globally. Recent data showed the detrimental effects of COVID-19 infection on other neoplasm conditions, causing increased mortality rates and complications. However, data on the precise effects of COVID-19 on hospitalized individuals with lung cancer are scarce. Methods: We analyzed the 2020 U.S. National Inpatient Sample (NIS) to investigate the effects of COVID-19 infection on cases primarily admitted due to lung and bronchus cancer. Adjusted odds ratios (aORs) for specified outcomes were calculated through multivariable logistic and linear regression analyses. The primary outcome was inpatient mortality, with secondary outcomes including system-based complications. Statistical significance was established at a p-value of 0.05. Results: We identified 103,334 patients with a primary discharge diagnosis of lung and bronchus cancer. The mean age was 68.9 years; 50.5% were female. In the non-COVID group, Caucasians accounted for 75%, followed by Hispanics (12%). Of these, 0.36% (374/103,334) had a concurrent diagnosis of COVID-19 infection. In a survey multivariable logistic and linear regression model adjusting for patient and hospital factors, COVID-19 infection was associated with higher in-hospital mortality (aOR 5.39; 95% CI (3.01, 9.64), p &lt; 0.001), higher mean length of stay (b 5.51; 95% CI (2.59, 8.43) p &lt; 0.001), mean total hospital cost (b 10,683; 95% CI (784.32, 20,581.93) p = 0.034), shock (aOR 4.37; 95% CI (1.96, 9.91), p &lt; 0.001), acute respiratory failure (aOR 2.23; 95% CI (1.30, 3.85), p = 0.004), mechanical ventilation usage (aOR 3.12; 95% CI (1.46, 6.66), p = 0.003) and acute kidney injury (aOR 2.71; 95% CI (1.54, 4.74), p &lt; 0.001). We observed non-significant, but increased, risks of sepsis, SIRS, and coagulopathy in COVID-19-positive patients. Conclusions: In conclusion, our study underscores that COVID-19 infection is associated with higher in-hospital mortality and other major clinical outcomes in lung cancer, as well as increased economic burden and cost of stay. To definitively establish causal relationships between the observed factors and the reported clinical outcomes in this population, further longitudinal research is necessary.

Impact of the COVID-19 Pandemic on Self-Confidence in Patient Treatment in the Endodontic and Restorative Procedures of Dentistry Students at the University of Novi Sad.

(1) Background: The COVID-19 pandemic has brought about a change in the concept of teaching with the introduction of online lectures and "distance learning." The aim of this study was to determine the impact of the COVID-19 pandemic on the confidence and both theoretical and practical knowledge of dental students regarding the courses in conservative dentistry and endodontics. (2) Methods: The study was conducted using an originally created online questionnaire consisting of 30 questions that the students used to make a subjective assessment of their confidence in performing both endodontic and conservative procedures using numerical scales. They were divided into two groups, a non-COVID group of students, who attended classes before the outbreak of the pandemic, and a COVID group, whose classes were suspended due to the lockdown. The data were processed in the SPSS statistic 25 program, with statistical significance p < 0.05. (3) Results: The comparison of the self-assessment of 96 students from the COVID group and 91 students from the non-COVID group revealed significant results. Compared with the COVID group, the non-COVID students felt more confident in the application of anesthesia in both the maxilla and mandible, in the initial treatment of patients in pain, as well as in all the steps of the endodontic treatment. Both groups felt equally confident in diagnostic and conservative procedures, and the level of theoretical knowledge acquired in the courses. (4) Conclusions: Changes in teaching due to the COVID-19 pandemic had an unfavorable effect on students' self-confidence in performing routine dental interventions, especially in the endodontic field. The lack of confidence in the COVID group regarding the anesthetic and endodontic procedures appears due to their inability to do any of these procedures during the COVID period; we organized summer practical school under the supervision of teachers, and they gained the necessary knowledge and self-confidence for these procedures.

COVID vs. non-COVID oncology patient cohorts: Demographics and cancer variables.

e23046 Background: This study aimed to compare demographics and cancer-specific variables in oncology patients hospitalized with (n = 551) and without COVID-19 (n = 3674) during the first year of the pandemic. Methods: We analyzed prospectively collected data from March 2020 to February 2021 at a major US cancer center, comparing age, sex, cancer category, race, metastasis, treatments within one month prior to admission, and smoking history. Results: The study found no significant difference in mean age between COVID and non-COVID cohorts (60.7% vs. 60.9%; p = 0.830). Significant differences (p = 0.002) in cancer categories were noted between COVID and non-COVID cohorts. Hematological cancers had the highest hospitalization rates in both groups (38.8% vs 29.2%). Statistically significant racial differences were observed between COVID and non-COVID cohorts (p &lt; 0.001). Whites had the highest hospitalization rates in both groups, yet COVID-related admissions were lower for Whites (COVID cohort: 51.2% vs non-COVID cohort: 61.9%) and Asians (COVID cohort: 2.7% vs non-COVID cohort: 5.9%) compared to non-COVID admissions, while higher for Blacks (COVID cohort: 15.4% vs non-COVID cohort: 14%) and Hispanics (COVID cohort: 28.3% vs non-COVID cohort: 15.7). Significant differences (p &lt; 0.001) were noted in metastasis prevalence between COVID and non-COVID hospitalizations, with rates of 81.3% and 86.0%, respectively. Conversely, non-metastatic cancer was more prevalent in COVID hospitalizations (18.1%) than in the non-COVID cohort (8.7%). In the COVID cohort, 30.5% received chemotherapy within one month before admission, compared to 43.8% in the non-COVID cohort, showing a significant difference in admission rates (p &lt; 0.001). Similarly, recent immunotherapy (8.0% vs. 10.9%) and recent surgery (3.6% vs. 6.6%) were associated with higher hospitalization rates in the non-COVID cohort (p = 0.046 and p = 0.010, respectively). We observed significant differences (p &lt; 0.001) in the smoking history of the COVID and. non-COVID cohorts. While 2.5% of COVID patients were current smokers, 5.4% of non-COVID patients were, more than double the COVID rate. In the COVID cohort, 36.3% were former smokers, slightly lower than the 37.6% in the non-COVID cohort. Additionally, 59.3% of COVID patients were never smokers, compared to 56.3% in the non-COVID group. Conclusions: COVID-related admissions were lower for Whites and Asians compared to non-COVID admissions, while higher for Blacks and Hispanics. Lower rates of metastasis were noted in COVID cohort. Lower rates of hospitalizations among patients who received chemotherapy, immunotherapy, and surgery were observed in the COVID cohort. The smoking prevalence was higher in the non-COVID group, former smoking rates were similar across cohorts, and a higher proportion of COVID patients were never smokers.

Sonographic assessment of the diaphragm in COVID 19 and non-COVID ICU patients

BackgroundSonographic evaluation of the diaphragm has gained popularity in the ICU due to the necessity of assessing diaphragmatic function in a variety of clinical situations. The sonographic examination of diaphragmatic dynamics in ICU patients by measuring diaphragmatic thickness and excursion in connection to various modalities of mechanical ventilation (MV) and patient outcomes was the objective of this study.MethodsThis prospective observational study was carried out on 50 patients in respiratory ICU in Kafr Elsheikh and Benha University Hospitals. Patients were classified into 2 equal groups: COVID-19 group and non-COVID group. All patients underwent ultrasound assessment included the diaphragm thickness fraction and excursion in ICU patients on admission and on weaning.ResultsSuccessful weaning (SW) was higher in group I compared to group II. In group I (COVID), diaphragm excursion, thickness at end inspiration and at end expiration in NIV at weaning were significantly higher in patients with SW but thickness at end expiration on admission was significantly lower. In group II (non-COVID) MV patients, excursion at weaning was significantly higher in patients with SW, also were thickness at end inspiration and end expiration on admission, thickness at end inspiration and end expiration at weaning in NIV patients but thickness at end inspiration in MV on admission was significantly lower.ConclusionWeaning success and mortality were significantly predicted by excursion in NIV at weaning, thickness at end inspiration in MV at weaning, thickness at end inspiration in NIV at weaning, and thickness at end expiration in MV at weaning.

Comparison of lifestyle, cognitive function, mental health, and quality of life between hospitalized older adults with COVID-19 and non-COVID-19 in South Korea: a cross-sectional study

BackgroundThe coronavirus disease (COVID-19) pandemic has greatly impacted older adults, resulting in many deaths. The impact of lifestyle and mental health on vulnerable groups, such as older adults, can be large and long lasting. Therefore, this study aimed to investigate the effects of COVID-19 confirmation on cognition, lifestyle, mental health, and quality of life in adults aged 55 years.MethodsThe sample consisted of 111 people in the COVID group and 189 people in the non-COVID group aged over 55 years in South Korea. An online survey was conducted between January and May 2022. Participants responded to the following assessment tools: Yonsei Lifestyle Profile, Prospective and Retrospective Memory (PRMQ), Subjective Memory Complaints Questionnaire (SMCQ), Visual Analogue Scale, Patient Health Questionnaire-9 (PHQ-9), Insomnia Severity Index (ISI), Fear of COVID-19 Scale (FCV-19 S), and the World Health Organization Quality of Life Scale abbreviated version (WHOQOL-BREF). Differences in lifestyle, cognition, depression, anxiety, and quality of life were compared between the two groups.ResultsThere were significant differences in physical activity, diet, the total score of the PRMQ, PM (a sub-score of the PRMQ), PHQ-9, Korean version of the ISI (ISI-K), and WHOQOL-BREF scores between the COVID and non-COVID groups. However, there were no significant differences in activity participation, Self-Rating Anxiety Scale (SAS), or FCV-19 S between groups.ConclusionsThe study confirms that COVID-19 negatively affects memory, physical activity, diet, quality of life, depression, and insomnia in the older adults. Therefore, this study implicated that prevention and intervention strategies required improving the memory, lifestyle, and mental health of older adults with COVID-19.Trial registrationThe study was conducted in accordance with the Declaration of Helsinki, and approved by the Institutional Review Board of Yonsei university in Korea (Registration number: 1041849-202112-SB-226-03, Date of registration: 01042022).

Coping self-efficacy and personal growth in the situation of the COVID-19 threat

IntroductionIn studies of the socio-psychological consequences of the COVID-19 pandemic, models focused on the negative aspects of stressors, dysfunctions, anxiety We present the attempt to expand the context and include in the field positive personal resources for psychological well-being and even post traumatic personality growth after disasters. Sometimes separation from family and friends, lack of medicines and medical resources, loss of income, social isolation to humanity, do not automatically assume that a person is capable and responsible for effectively coping with life difficulties.Objectives397 (students and patients of clinic average age 26, 2/3 are femaleMethodsPeritraumatic Distress Index (CPDI) (Feng, 2020); Impact of Event Scale (Horowitz, 1979), Coping Self-efficacy Scale (Chespeu et al, 2006); Posttraumatic Growth Inventory (Tedeschi&amp; Calhoun, 1996), MMI (Nuttin, 1986) – adapted by M. Magomed-Eminov.ResultsSignificant negative correlation between coping self-efficacy and intensity of the impact of stressful events (IES) (rS = - 0,140, p &lt; 0,05) was predictable.CPDI and PTG showed significant correlation (Pearson’s r= 0.23, p&lt;0.01) between Peritraumatic Distress Index and Post-Traumatic Growth indicators only in the group of respondents who have had COVID-19. The data is confirmed by the content analysis of incomplete sentences of the subjects of COVID group. The correlation between these indicators in the Non-Covid group was insignificant.Moreover additional information we got from narratives of infected patients: the data has been split into 3 groups of narratives in the context of cultural-historical activity theory which shows the triadic outcome of survivor after trauma : a) suffering, b) adaptation, coping, resilience, c) personal growth.ConclusionsTo interpret the data the authors propose the meaning-activity approach and personality work with negative life experience (Magomed-Eminov, 1998, 2007, 2009, 2021). Authors suggest that further research on the positive consequences of stressful events beside coping styles and mechanisms that would expand the repertoire of tools predicted the ability of a modern person to cope with adversity and use experience for deeper involvement of human resources with the help of personality work with personal experience.Disclosure of InterestNone Declared

Symptom intensity of post-COVID and long COVID syndromes in patients entering rehabilitation treatment.

The problem of post-COVID symptoms is still being analysed. Many of them may be related to other conditions, but the new appearance and greater intensity of some of them, e.g. fatigue, musculoskeletal pain, and neuropathic pain, seem to be related to a previous viral infection. Efforts are being made to determine in more detail the most characteristic symptoms of post-COVID syndrome. The conditions of rehabilitation after COVID-19 provide an opportunity for such observations. In rehabilitation centres and sanatoriums, it is possible to compare patients with post-COVID syndrome and other patients referred for rehabilitation, who constitute a natural control group. Such a comparison is the aim of the present work. The study included 59 post-COVID-19 patients and 57 sanatorium patients without COVID (non-COVID group) as a control group. The 31-element questionnaire ("Post-COVID syndrome symptoms assessment card") was part of the routine management of post-COVID patients referred for rehabilitation after symptomatic SARS-CoV-2 infection in Polish conditions. In the control group, the questionnaire was introduced as a part of a physical examination and an interview regarding the symptoms reported by the patient before standard rehabilitation. The questions were scored in the scale from 0 to a maximum of 10 points. Each patient gave informed consent to the use of the questionnaire for research purposes. Symptoms of the highest intensity in the COVID-19 group were: feeling unwell after physical effort (avg. 6.25 points), chronic fatigue (avg. 5.97 points), dyspnoea on exertion (avg. 5.83 points), concentration disturbances (avg. 4.93), muscle pain (avg. 4.92), joint pain (avg. 4.86), memory disorders (avg. 4.81 points), sleep disorders (avg. 4.05 points), numbness of the limbs (avg. 3.73 points), tingling in the limbs (avg. 3.68 points).Symptoms of highest intensity in patients in the non-COVID-19 group: joint pain (avg. 4.61 points), tingling in the limbs (avg. 2.84 points), numbness of the limbs (avg. 2.79 points), muscle pain (avg. 2.11 points).There was no statistically significant difference between the group under examination and the control group in the following symptoms: fever, diarrhoea, abdominal pain, resting dyspnoea, olfactory disorders, joint pain, tingling in the limbs and numbness of the limbs. The results of this study show symptoms of the highest intensity with post-COVID syndromes. However, also symptoms that are a problem both in post-COVID and non-COVID patients, i.e. joint pain, tingling in and numbness of the limbs were identified. This confirms that the control non-COVID group consisted of patients referred for rehabilitation treatment mainly due to musculoskeletal problems and chronic pain.

Changes in sensitivity and hedonic rating to transcutaneous electrical nerve stimulation following COVID-19

COVID-19 affects not only the respiratory system but also other biological systems such as the nervous system. Usually, these changes are reported based on the patient's subjective description. The aim of our study, therefore, was to objectively determine the effect that the SARS-CoV-2 virus and COVID-19 disease has on sensory threshold and the hedonic and subjective perception of an electrical stimulus. The sensory threshold was tested on the inner forearm by applying non-invasive transcutaneous electrical nerve stimulation (TENS) with 100 Hz and 100 µs parameters and a biphasic current waveform. The study involved 211 participants, aged 22–79 years, with a mean age of 56.9 ± 12.1 years. There were 131 subjects in the COVID group, while the NON-COVID group, the control group, was matched to the COVID group in terms of gender, age, body mass index and presence of chronic diseases. The research was carried out in 2022. Sensory sensitivity was highest in the group that had suffered with COVID-19. The median sensory sensitivity was 11 mA in the COVID group and 14 mA (p < 0.001) in the NON-COVID group, however, the current sensitivity threshold decreased over time (R = 0.52, p < 0.001). Post COVID-19, the electrical stimulus was more often perceived as unpleasant: COVID versus NON-COVID (23% vs. 3%, p < 0.001) and as a different sensation to tingling (27% vs. 2%, p < 0.001). Post-COVID-19 patients have a lower sensory threshold, the electrical stimulus is more often described as unpleasant and in subjective feelings it is more often described as pinching. The differences between COVID and NON-COVID decrease with time since the onset of COVID symptoms.

Cognitive and mental health trajectories of COVID-19: Role of hospitalisation and long-COVID symptoms.

There is considerable evidence of cognitive impairment post COVID-19, especially in individuals with long-COVID symptoms, but limited research objectively evaluating whether such impairment attenuates or resolves over time, especially in young and middle-aged adults. Follow-up assessments (T2) of cognitive function (processing speed, attention, working memory, executive function, memory) and mental health were conducted in 138 adults (18-69years) who had been assessed 6months earlier (T1). Of these, 88 had a confirmed history of COVID-19 at T1 assessment (≥20days post-diagnosis) and were also followed-up on COVID-19-related symptoms (acute and long-COVID); 50 adults had no known COVID-19 history at any point up to their T2 assessment. From T1 to T2, a trend-level improvement occurred in intra-individual variability in processing speed in the COVID, relative to the non-COVID group. However, longer response/task completion times persisted in participants with COVID-19-related hospitalisation relative to those without COVID-19-related hospitalisation and non-COVID controls. There was a significant reduction in long-COVID symptom load, which correlated with improved executive function in non-hospitalised COVID-19 participants. The COVID group continued to self-report poorer mental health, irrespective of hospitalisation history, relative to non-COVID group. Although some cognitive improvement has occurred over a 6-month period in young and middle-aged COVID-19 survivors, cognitive impairment persists in those with a history of COVID-19-related hospitalisation and/or long-COVID symptoms. Continuous follow-up assessments are required to determine whether cognitive function improves or possibly worsens, over time in hospitalised and long-COVID participants.

Surgical and visual outcomes of flap repositioning for various flap-related pathologies post laser in-situ keratomileusis (LASIK).

To evaluate the surgical and visual outcomes of flap repositioning for various post-laser-assisted in-situ keratomileusis (LASIK) flap pathologies. Retrospective review of consecutive cases between April 1, 2017 and February 28, 2022, where surgical flap repositioning was performed following LASIK for various flap-related complications. Of the 6018 eyes, 31 needed flap repositioning (0.51%). Indications were flap displacement and folds in 20 eyes (64%), flap subluxation in five eyes (16%), epithelial ingrowth and interface debris in two each, and one eye each of diffuse lamellar keratitis and incomplete flap. Final best spectacle-corrected visual acuity of ≥ 20/25 was obtained in 25/31 (80%) eyes. The efficacy index pre to post repositioning showed significant improvement (0.86 ± 0.39 vs. 0.63 ± 0.29 preop, P = 0.011). Flap repositioning incidence was significantly higher (7/602 (1.16%)) during the COVID lockdown phases compared to the non-COVID lockdown phase (24/5416 (0.44%, P = 0.019)). The COVID group had lower efficacy (0.72 ± 0.36 vs. 0.90 ± 0.39, P = 0.300) and safety indices (0.85 ± 0.24 vs. 1.06 ± 0.35, P = 0.144) compared to the non-COVID group; however, the results were not statistically significant. The flap displacement rate was statistically higher in nasal hinged (microkeratome) flaps (18/2013, 0.89%) compared to superior hinged (Femto) flaps (13/4005, 0.32%) (0.32%, P = 0.003). Our study shows that flap repositioning has a low incidence in LASIK, with the most common indication being flap displacement/folds. The outcome post flap repositioning was poorer during the lockdown period, perhaps due to the inability to follow up early. Early identification and surgical repositioning are successful in both anatomical and visual restoration.

Post-COVID-19 cardio-pulmonary manifestations after 1-year of SARS-CoV-2 infection among Indian population: A single centre, case-control study (OneCoV2 study)

BackgroundThe evolving challenge of persistent symptoms post-Coronavirus disease-2019 (COVID-19), particularly debilitating cardio-pulmonary manifestations, necessitates further exploration. Our study aimed to assess the cardio-pulmonary complications in patients a year after hospital discharge from severe COVID-19, contrasting these with findings from a non-COVID group. MethodsThe OneCoV2 study, a prospective, case-control study, was conducted at a tertiary care teaching hospital in northern India. We enrolled 43 subjects, with a mean age of 25.57 ± 7.94 years (COVID group) and 27.30 ± 8.17 years (non-COVID group). Comprehensive tests included pulmonary function tests, cardiac function tests, 6-min walk tests, and laboratory investigations. ResultsSignificant differences were found in the pulmonary function [forced vital capacity (FVC) (p = 0.037), forced expiratory flow (FEF) 25–75 % (p = 0.013)], and cardiac function [left ventricular ejection fraction (LVEF) (p = 0.032), heart rate (HR) (p = 0.047)], along with the six-minute walk test results between the two groups. In the COVID group, Pearson's correlation showed a negative correlation between FVC and C-reactive protein (CRP) [r = −0.488, p = 0.007] and a positive correlation between the six-minute walk test [r = 0.431, p = 0.003] and HR [r = 0.503, p = 0.013]. ConclusionsOur data suggest that pulmonary abnormalities are prevalent in COVID patients even after 1-year of hospital discharge. Cardiac biomarkers also show an inclination towards the COVID group. While we found significant correlations involving some parameters like FVC, CRP, HR, and results from the six-minute walk test, we did not find any significant correlations with the other tested parameters in our study.

Global prevalence of respiratory virus infections in adults and adolescents during the COVID-19 pandemic: A systematic review and meta-analysis

ObjectivesSince the beginning of the COVID-19 pandemic, efforts have been made to contain the spread of the virus. However, the epidemiological burden of other respiratory viruses during the pandemic is unclear. We aim to address the epidemiology of respiratory viruses on adults/adolescents since the beginning of the pandemic. MethodsWe systematically searched five databases and performed a meta-analysis to explore the pooled prevalence of respiratory viruses in different geographical regions, age groups, and periods and compared the prevalence between COVID-19 cases and non-COVID-19 patients. ResultsEnteroviruses/rhinoviruses were highly prevalent compared to other viruses. Different viruses were dominant in different regions. No significant differences in prevalence were found between different age groups, except for human metapneumovirus. There was an increase in prevalence of non-SARS-CoV-2 viruses in the second half of the pandemic (July 2021-December 2022). Comparison of COVID-19 and non-COVID patients showed a higher prevalence in the non-COVID group, significant for influenza, seasonal coronaviruses, and human parainfluenza viruses. ConclusionOur findings indicate that enteroviruses/rhinoviruses were less impacted by healthcare measures compared with other respiratory viruses. The relaxation of measures in the second half led to an increased pooled prevalence of infections. Several factors may explain the lower prevalence among individuals infected with COVID-19.

FRI469 Natural History Of de Quervain’s Thyroiditis In The Era Of COVID -19: The Greek Experience Of 226 Cases

Abstract Disclosure: N. Angelopoulos: None. D.P. Askitis: None. I. Androulakis: None. N. Valvis: None. R. Paparodis: None. V. Petkova: None. A. Boniakos: None. D. Zianni: None. I. Perogamvros: None. K.A. Toulis: None. S. Livadas: None. Background: Subacute thyroiditis (SAT) is a usually self-limiting disease however,patients with pronounced tenderness normally receive nonsteroidal anti-inflammatorydrugs (NSAIDs) or systemic steroids. Disease recurrence is unfortunately common, while approximately 0.5-15% of patients require permanent thyroxine substitution. Among the thyroid SARS-CoV-2 complications, SAT was reported early and the question whether SAT might be underestimated was raised. Aims and Scope: The aims of this retrospective study were: (1) to determine predictive factors for SAT recurrence and the development of hypothyroidism and (2) to identify potential clinical and laboratory characteristics in patients with SAT due to SARS-CoV-2 infection. Methods: We retrospectively reviewed the records of 226 patients with confirmed subacute thyroiditis between January 2020 and November 2022 in eleven outpatient endocrine clinics with geographical representativeness of Greek territory. Results: Mean age was 48.01 years and F/M 158/68. Baseline hypothyroidism was present in 11 patients (4.86%), 36 had Hashimoto, 30 had nodular disease, 4 had both Hashimoto and nodules, 1 was hyperthyroid and the remaining 144 patients had no thyroid disease. At the end of follow up (16.77±0.8 months) 68 patients (34.5%) had hypothyroidism (P &amp;lt;0.001, 15 of them with nodules), 17 Hashimoto, 4 Hashimoto and nodular disease, 1 developed hyperthyroidism and 1 was thyroidectomized due to multiple recurrences. Regarding treatment protocols, significant differences were detected for treatment duration (shorter with ibuprofen, p&amp;lt;0.001), time-to-symptoms relief (shorter with methylprednisolone, p&amp;lt;0.05) and the initial equivalent dose of cortisone (lower in combined treatment with cortisone and ibuprofen, p&amp;lt;0.001). Demographical (age, gender, BMI), serological (ESR,CRP) and treatment parameters (type of therapy, duration of therapy, initial dose of treatment, time to treat, time to symptoms relief) were not related with the development of hypothyroidism. Recurrence was observed in 28 patients (14.1%) all treated with glucocotricoids. 34 patients had covid-19 related SAT with no specific clinical manifestation of the disease. Compared to the non-covid group, BMI was higher (27.58±4.05 vs 25.69±5.44, respectively, p=0.026) and a shorter time-to-symptoms relief was observed (3.56±1.94 vs 5.46±6.93 days, respectively, p=0.044). Conclusion: In a large cohort of patients, corticosteroid therapy was found to promptly alleviate the acute symptoms during the onset of SAT, duration of treatment was longer and the incidence of recurrence greater than that observed with nonsteroidal anti-inflammatory drugs. Both regimens could not prevent the development of delayed hypothyroidism. Clinical characteristics of SAT after COVID-19 were similar to those of typical SAT. Presentation: Friday, June 16, 2023

Impact of SARS-CoV-2 Infection on Maternal and Neonatal Outcome in Correlation with Sociodemographic Aspects: A Retrospective Case-Control Study.

As the COVID-19 pandemic evolved, concerns grew about its impact on pregnant women. This study aimed to determine how SARS-CoV-2 affects pregnancy, birth, and newborns, in order to identify vulnerable individuals and provide proper care. This is a retrospective case-control study of 398 pregnant women who delivered at the Emergency Clinical County Hospital in Sibiu, Romania from 1 February 2020 to 31 March 2022. Patients were initially grouped and compared based on their RT-PCR SARS-CoV-2 test results into the COVID group (cases) (N = 199) and non-COVID group (control) (N = 199). The COVID cases were further divided and compared according to the pre-Delta (N = 105) and Delta/Omicron (N = 94) SARS-CoV-2 variants. COVID cases and control groups were compared to identify correlations between sociodemographic factors, pregnancy outcomes, and SARS-CoV-2 infection. The same comparisons were performed between pre-Delta and Delta/Omicron groups. There were no significant differences concerning maternal residence, while educational level and employment proportion were higher among the positively tested patients. No significant differences were found for neonatal and pregnancy complications between COVID cases and control groups. Except for a lower mean gestational age, no significant differences were found between pre-Delta and Delta/Omicron periods. The maternal mortality in the infected group was 0.5% (1 case). Our study showed that SARS-CoV-2 infection at birth did not significantly affect maternal and neonatal outcomes, not even considering the SARS-CoV-2 strain.
