The mediation effects of COVID-19-related traumatic stress symptoms and mentalization on the relationship between perceived stress and psychological well-being in healthcare workers transitioning to a post-pandemic world.

BACKGROUND: In context of COVID-19 as a collective trauma and the intense involvement of healthcare workers (HCWs) in the pandemic, perceived stress continues to have a tremendous impact on their psychological well-being. However, few studies have attempted to delineate the underlying mechanisms. This study examined whether COVID-19-related traumatic stress symptoms and mentalization act as mediators. METHODS: A sample of HCWs (N = 2610) from 22 hospitals in Beijing, China participated in this cross-sectional investigation. Data on their perceived stress, psychological well-being, the impact of event, and reflective function during the COVID-19 pandemic were collected using self-report questionnaires. Different mediating models were tested. RESULTS: COVID-19-related stress symptoms and mentalization independently mediate the association between perceived stress and psychological well-being. These two mediators also compose a serial mediation model. In particular, higher perceived stress inhibits the psychological well-being of HCWs through increased severity of traumatic stress symptoms, which in turn is associated with hypomentalizing. CONCLUSION: These findings shed light on the mechanisms underlying the relationship between perceived stress and psychological well-being in HCWs. We strongly recommend incorporating a mentalization framework with trauma-informed practice in prevention and intervention work with this population during this and future healthcare crisis.

COVID-19 and Rates of Cancer Diagnosis in the US.

Importance: US cancer diagnoses were substantially lower than expected during the COVID-19 pandemic in 2020. A national study on the extent to which rates recovered in 2021 has not yet been conducted. Objective: To examine observed vs expected cancer rate trends for January 2020 to December 2021. Design, Setting, and Participants: This cross-sectional, population-based study of cancer incidence trends used the Surveillance, Epidemiology, and End Results 22 (SEER-22) Registries Database, which covers 47.9% of the US population. Included individuals were those with an invasive cancer diagnosis reported to registries included in SEER-22 between January 1, 2000, and December 31, 2021. Exposures: Age, sex, race and ethnicity, urbanicity, and stage at diagnosis. Main Outcomes and Measures: Expected cancer incidence rates were measured for the COVID-19 pandemic years of 2020 and 2021 from prepandemic trends using ensemble forecasting methods. Relative difference between observed and expected cancer incidence rates and numbers of potentially missed cases were measured. Results: The SEER-22 registries reported 1 578 697 cancer cases in 2020 and 2021, including 798 765 among male individuals (50.6%) and 909 654 among persons aged 65 years or older (57.6%). Observed all-sites cancer incidence rates were lower than expected by 9.4% in 2020 (95% prediction interval [PI], 8.5%-10.5%), lower than expected by 2.7% in 2021 (95% PI, 1.4%-3.9%), and lower than expected by 6.0% across both years combined (95% PI, 5.1%-7.1%), resulting in 149 577 potentially undiagnosed cancer cases (95% PI, 126 059-176 970). Of the 4 screening-detected cancers, only female breast cancer showed significant recovery in 2021, exceeding expected rates by 2.5% (95% PI, 0.1%-4.8%), while significant reductions remained for lung cancer (9.1% lower than expected; 95% PI, 6.4%-13.2%) and cervical cancer (4.5% lower than expected; 95% PI, 0.4%-8.0%), particularly for early stage at diagnosis. Rates of all-sites cancer incidence returned to prepandemic trends in 2021 among female individuals, persons aged younger than 65 years, and persons of non-Hispanic Asian and Pacific Islander race and ethnicity. Conclusions and Relevance: This population-based cross-sectional study of US cancer incidence trends found that rates of diagnosis improved in 2021 but continued to be lower than expected, adding to the existing deficit of diagnosed cases from 2020. Particular attention should be directed at strategies to immediately increase cancer screenings to make up lost ground.

Primary series COVID-19 vaccine effectiveness among health care workers in the country of Georgia, March-December 2021.

BACKGROUND: Healthcare workers (HCWs) have suffered considerable morbidity and mortality during the COVID-19 pandemic. Few data on COVID-19 vaccine effectiveness (VE) are available from middle-income countries in the WHO European Region. We evaluated primary series COVID-19 VE against laboratory-confirmed COVID-19 among HCWs in Georgia. METHODS: HCWs in six hospitals in Georgia were invited to enroll in a prospective cohort study conducted during March 19-December 5, 2021. Participants completed weekly symptom questionnaires. Symptomatic HCWs were tested by RT-PCR and/or rapid antigen test (RAT), and participants were routinely tested for SARS-CoV-2 by RT-PCR or RAT, regardless of symptoms. Serology was collected at enrolment, and quarterly thereafter, and tested by electrochemiluminescence immunoassay for SARS-CoV-2 antibodies. We defined primary series vaccination as two doses of COVID-19 vaccine received ≥14 days before symptom onset. We estimated VE as (1-hazard ratio)*100 using a Cox proportional hazards model with vaccination status as a time-varying covariate. Estimates were adjusted by potential confounders that changed the VE estimate by more than 5%, according to the change-in-estimate approach. RESULTS: Overall, 1561/3849 (41%) eligible HCWs enrolled and were included in the analysis. The median age was 40 (IQR: 30-53), 1318 (84%) were female, and 1003 (64%) had laboratory evidence of prior SARS-Cov-2 infection. At enrolment, 1300 (83%) were unvaccinated; By study end, 1082 (62%) had completed a primary vaccine series (69% BNT162b2 (Pfizer-BioNTech); 22% BBIBP-CorV (Sinopharm); 9% other). During the study period, 191(12%) participants had a new PCR- or RAT-confirmed symptomatic SARS-CoV-2 infection. VE against PCR- or RAT- confirmed symptomatic SARS-CoV-2 infection was 58% (95%CI: 41; 70) for all primary series vaccinations, 68% (95%CI: 51; 79) for BNT162b2, and 40% (95%CI: 1; 64) for BBIBP-CorV vaccines. Among previously infected HCWs, VE was 58% (95%CI: 11; 80). VE against medically attended COVID-19 was 52% (95%CI: 28; 68), and VE against hospitalization was 69% (95% CI: 36; 85). During the period of predominant Delta variant circulation (July-December 2021), VE against symptomatic COVID-19 was 52% (95%CI: 30; 66). CONCLUSIONS: Primary series vaccination with BNT162b2 and BBIBP-CorV was effective at preventing COVID-19 among HCWs, most of whom had previous infection, during a period of mainly Delta circulation. Our results support the utility of COVID-19 primary vaccine series, and the importance of increasing coverage, even among previously infected individuals.

Fungal coinfection/superinfection in COVID-19 patients in a tertiary hospital in Mexico / Coinfección o sobreinfección fúngica en pacientes con COVID-19 en un hospital de tercer nivel en México

Introduction: Data on the prevalence of fungal coinfections/superinfections in patients with COVID-19 are limited. Objective: To describe the prevalence of fungal coinfections/superinfections in patients with COVID-19, as well as risk factors and demographic, clinical, and microbiological characteristics. Material and methods: We included patients with a confirmed COVID-19 diagnosis and a confirmed fungal infection hospitalized in the ICU from March 2020 to December 2021. We collected data on age, sex, comorbidities, hospital length of stay (days), laboratory (ferritin) and microbiological results, treatment for COVID-19, antifungal therapy, and outcomes obtained from the clinical records. Results: Only 11 out of 740 patients met the inclusion criteria. The coinfection rate was 0.3% and the superinfection was 1.2%. The most affected population was male adults. The coinfections/superinfections diagnosed were candiduria and candidemia, caused by Candida albicans, C. tropicalis, C. glabrata, C. lusitaniae, and Kluyveromyces marxianus (C. kefyr). In addition, tracheobronchitis due to Aspergillus fumigatus was found. The most used antifungals were fluconazole and caspofungin. The lethality in patients with fungal coinfections was 50% and superinfections, 22%. The length of hospital stay was 11-65 days. Eight patients required mechanical ventilation and six received corticosteroids. The main comorbidity was diabetes mellitus (81.8%). Conclusions: The rate of fungal coinfections/superinfections in COVID-19 patients was low, but the lethality found urges for routine fungal screening in patients with severe COVID-19 to timely detect fungal infections that may further compromise the patient's life.

Introducción: Los datos sobre la prevalencia de coinfecciones o sobreinfecciones fúngicas en pacientes con COVID-19 son limitados. Objetivo: Describir la prevalencia de coinfecciones o sobreinfecciones fúngicas en pacientes con COVID-19, así como los factores de riesgo y las características demográficas, clínicas y microbiológicas. Material y métodos: Se incluyeron pacientes con diagnóstico confirmado de COVID-19, hospitalizados en la unidad de cuidados intensivos y con infección fúngica confirmada entre marzo del 2020 y diciembre del 2021. Del expediente clínico se obtuvieron datos sobre edad, sexo, comorbilidades, días de estancia hospitalaria, resultados de laboratorio (ferritina) y microbiológicos, tratamiento contra COVID-19, terapia antifúngica y desenlace. Resultados: Once de 740 pacientes cumplieron con los criterios de inclusión. La tasa de coinfección fue del 0,3 % y la de sobreinfección fue del 1,2 %. La población más afectada fue la de hombres adultos. Las coinfecciones o sobreinfecciones diagnosticadas fueron candiduria y candidemia, causadas por Candida albicans, C. tropicalis, C. glabrata, C. lusitaniae y Kluyveromyces marxianus (C. kefyr). Además, se encontró una traqueobronquitis por Aspergillus fumigatus. Los antifúngicos más administrados fueron fluconazol y caspofungina. La letalidad en pacientes con coinfecciones fue del 50 % y con sobreinfecciones fúngicas, del 22 %. El tiempo de estancia intrahospitalaria fue de 11 a 65 días. Ocho de los pacientes requirieron asistencia respiratoria mecánica y seis recibieron corticoides. La principal comorbilidad fue diabetes mellitus (81,8 %). Conclusiones: La tasa de coinfecciones o sobreinfecciones por hongos en pacientes con COVID-19 fue baja, pero la letalidad de estas requiere, con urgencia, la realización de pruebas de rutina para detectar hongos en pacientes con COVID-19 grave para diagnosticar oportunamente infecciones fúngicas que puedan comprometer aún más la vida del paciente.

HCoV-NL63 and HCoV-HKU1 seroprevalence and its relationship with the clinical features of COVID-19 patients from Villavicencio, Colombia / Seroprevalencia de HCoV-NL63 y HCoV-HKU1 y su relación con las características clínicas de pacientes con COVID-19 de Villavicencio, Colombia

INTRODUCTION: Due to the cross-reactivity between SARS-CoV-2 and common human coronaviruses, previous infections with these viruses could contribute to serological or cellular cross-protection against severe COVID-19. However, protective immunity may not develop, or pre-existing immunity could increase COVID-19 severity. OBJECTIVE: To determine the seroprevalence of IgG antibodies against HCoV-NL63 and HCoV-HKU1 and correlate previous exposure with COVID-19 signs in patients from Villavicencio. MATERIALS AND METHODS: A cross-sectional retrospective study was conducted. ELISA technique was used to search for IgG antibodies against HCoV-NL3 and HCoV-HKU1 in patients with positive RT-qPCR results for SARS-CoV-2. Patients were grouped according to COVID-19 clinical characteristics in four groups: group 1: asymptomatic (n = 23); group 2: hospitalized (n = 24); group 3: intensive care units (n = 24), and group 4: dead (n = 22). RESULTS: The overall seroprevalence of IgG antibodies against HCoV was 74.2% (n = 69; 95% CI: 65.3-83.1), with 66.7% of HCoV-NL63 (n = 62; 95% CI: 57,1-76,2), and 25.8% of HCoV-HKU1 (n = 24; 95% CI: 16,9-34,7). Based on crosstab analysis, prior exposure to HCoV-NL63 was associated with protection against severe COVID-19 (p = 0.042; adjusted OR = 0.159; 95% CI: 0.027-0.938), and previous coinfection of HCoV-NL63 and HCoVHKU1 was considered a positive association to severe COVID-19 (p = 0.048; adjusted OR = 16.704; 95% CI: 1.020 - 273.670). CONCLUSION: To our knowledge, this is the first study addressing seroprevalence of HCoV IgG antibodies in Colombia and Latin America. Previous exposure to HCoV-NL63 could protect against severe COVID-19, whereas patients with underlying HCoV-NL63 and HCoVHKU1 coinfection could be hospitalized with severe signs of COVID-19.

Introducción: Debido a la reactividad cruzada entre SARS-CoV-2 y los coronavirus humanos comunes, las infecciones previas con estos virus podrían contribuir a la protección cruzada serológica o celular contra la COVID-19 grave. Sin embargo, la inmunidad protectora puede no desarrollarse o la inmunidad preexistente podría generar COVID-19 grave. Objetivo: Determinar la seroprevalencia de anticuerpos IgG frente a HCoV-NL63 y HCoVHKU1, y correlacionar su previa exposición con los signos de COVID-19 en pacientes de Villavicencio. Materiales y métodos: Se realizó un estudio retrospectivo observacional analítico y transversal. Se utilizó la técnica ELISA para buscar anticuerpos IgG contra HCoV-NL3 y HCoV-HKU1 en pacientes con resultado positivo de RT-qPCR para SARS-CoV-2. Los pacientes se agruparon según los signos de COVID-19 en cuatro grupos: grupo 1: asintomáticos (n = 23); grupo 2: hospitalizados (n = 24); grupo 3: unidad de cuidados intensivos (n = 24), y grupo 4: fallecidos (n = 22). Resultados: La seroprevalencia general de IgG anti-HCoV fue de 74.2 % (n = 69; IC95%: 65,3-83,1), con 66,7 % de HCoV-NL63 (n = 62; IC95% :57,1-76,2) y 25,8 % de HCoV-HKU1 (n = 24; [IC95%:16,9-34,7). Según el análisis de las tablas de contingencia, la exposición previa a HCoV-NL63 se asoció con protección de una COVID-19 grave (p = 0,042; OR ajustado = 0,159; IC95%: 0,027-0,938) y la previa coinfección de HCoV-NL63 y HCoV-HKU1 se asoció con padecimiento de signos clínicos graves por COVID-19 (p = 0,048; OR ajustado = 16,704; IC95%: 1,020- 73,670). Conclusión: Según la literatura revisada hasta la fecha, este es el primer estudio sobre la seroprevalencia de anticuerpos IgG de HCoV en Colombia y Latinoamérica. La exposición previa a HCoV-NL63 podría proteger contra la COVID-19 grave, mientras que los pacientes con coinfección subyacente de HCoV-NL63 y HCoV-HKU1 podrían resultar hospitalizados con signos graves de COVID-19.

Training health workers and community influencers to be Vaccine Champions: a mixed-methods RE-AIM evaluation.

INTRODUCTION: Increasing trust and confidence in vaccines is a global priority, as countries have grappled with delivering COVID-19 vaccines, maintaining routine childhood vaccination rates and introducing new vaccines. Community-based vaccine promotion interventions are commonly implemented, but effectiveness evidence is limited. In 2022, supported by the Australian Government and in partnership with Fiji's Ministry of Health and UNICEF, we codesigned, delivered and comprehensively evaluated a vaccine education and communication training programme for health workers and community influencers to promote COVID-19 and routine immunisation. METHODS: The Vaccine Champions programme included three phases: (1) codesign with Fiji stakeholders; (2) vaccine education and communication training for Vaccine Champions and (3) support for Champions to deliver community vaccine discussion sessions over 6 months.The RE-AIM framework evaluation measured programme reach, effectiveness, adoption, implementation and maintenance. Mixed-methods data were collected through interviews, surveys and field notes, integrating qualitative and quantitative data to triangulate findings. Primary outcomes included Champions' knowledge, communication self-efficacy, trust in COVID-19 vaccines, programme satisfaction and community members' intention to vaccinate. RESULTS: We trained 35 Champions (27/35 female), including health workers, faith and community influencers. Half had a health background (17/35). Champions conducted 54 discussion sessions, reaching 1717 community members. Most Champions (22/35) conducted at least 1 session, with 16 running 3 or more. Champions who did not run sessions reported barriers like lack of confidence and competing duties. Training increased Champions' communication self-efficacy and trust in COVID-19 vaccines. Community member intention to vaccinate increased from 41% (394/960) to 83% (822/991) before and after a session. The programme was well received with interest in continued engagement. CONCLUSION: Training health workers and community Vaccine Champions can promote vaccine confidence. Programmes require government support and engagement for sustainability. Robust evaluation frameworks are needed to build the evidence base.

Tactical capacity planning under uncertainty - a capacity limitation analysis.

PURPOSE: Tactical capacity planning is crucial when hospitals must cope with substantial changes in patient requirements, as recently experienced during the Covid-19 pandemic. However, there is only little understanding of the nature of capacity limitations in a hospital, which is essential for effective tactical capacity planning. DESIGN/METHODOLOGY/APPROACH: We report a detailed analysis of capacity limitations at a Norwegian tertiary public hospital and conducted 22 in-depth interviews. The informants participated in capacity planning and decision-making during the Covid-19 pandemic. Data are clustered into categories of capacity limitations and a correspondence analysis provides additional insights. FINDINGS: Personnel and information were the most mentioned types of capacity limitations, and middle management and organizational functions providing specialized treatment felt most exposed to capacity limitations. Further analysis reveals that capacity limitations are dynamic and vary across hierarchical levels and organizational functions. RESEARCH LIMITATIONS/IMPLICATIONS: Future research on tactical capacity planning should take interdisciplinary patient pathways better into account as capacity limitations are dynamic and systematically different for organizational functions and hierarchical levels. PRACTICAL IMPLICATIONS: We argue that our study possesses common characteristics of tertiary public hospitals, including professional silos and fragmentation of responsibilities along patient pathways. Therefore, we recommend operations managers in hospitals to focus more on intra-organizational information flows to increase the agility of their organization. ORIGINALITY/VALUE: Our detailed capacity limitation analysis at a tertiary public hospital in Norway during the Covid-19 pandemic provides novel insights into the nature of capacity limitations, which may enhance tactical capacity planning.

Since the COVID-19 pandemic, approximately 90% of elective anesthetics have been ambulatory: A retrospective analysis of statewide data in Florida from 2010 through 2022.

BACKGROUND: When the vast majority (e.g., ≈90%) of a specialty's elective (scheduled) care is ambulatory (i.e., length of stay 0 or 1 night), the administrative, clinical, and economic policy implications are profound. We examined the progressive shift of elective anesthetics in Florida from inpatient to ambulatory, from the first quarter of 2010 through the fourth quarter of 2022. We were particularly interested in the most recent data following the lifting of COVID-19 restrictions on elective surgery in the state. METHODS: This retrospective cohort study included major therapeutic and major diagnostic procedures with >0 American Society of Anesthesiologists base units in the state of Florida inpatient and ambulatory surgery databases. The last 8 quarters of these operating room anesthetic data corresponded to the end of restrictions on elective surgery in Florida due to the COVID-19 pandemic. Our goal was to determine whether the overall mean percentage of cases with 0- or 1-day lengths of stay has reached 90% since the lifting of pandemic restrictions. Numbers of cases over periods of at least four weeks tend to follow normal distributions. Therefore, we analyzed the N = 8 quarters of cases from 2021 to 2022 using Student's t-test. The study was performed when there were N = 8 quarters available from the Florida healthcare databases. RESULTS: There were overall 22,584,752 surgical cases studied. The percentages of elective anesthetics with length of stay ≤1-day increased progressively from 2010 through 2020. Among the eight successive quarters since the end of pandemic-related elective surgery restrictions, the percentage of elective cases with length of stay 0- or 1 day was stable, averaging 90% (95% two-sided confidence interval 89.4% to 90.3%). CONCLUSION: Since the COVID-19 pandemic, the mean quarterly percentage of elective surgery cases with anesthesia in Florida that were ambulatory has been reliably ≈90%. Implications include value in expecting overnight post-anesthesia care unit stay in ambulatory surgery centers and scheduling and sequencing cases based on post-anesthesia care unit capacity. Furthermore, because the vast majority (i.e., ≈90%) of cases would be excluded (i.e., not involve hospital admission for at least 2 midnights), there is a minimal role that risk-adjusted hospital length of stay and mortality can have in evaluating anesthesia department overall quality and economic effectiveness.

Understanding carbon resilience under public health emergencies: a synthetic difference-in-differences approach.

Public health emergencies influence urban carbon emissions, yet an in-depth understanding of deviations between regional emissions under such emergencies and normal levels is lacking. Inspired by the concept of resilience, we introduce the concept of regional carbon resilience and propose four resilience indicators covering periods during and after emergencies. A synthetic difference-in-differences model is employed to compute these indicators, providing a more suitable approach than traditional methods assuming unchanged levels before and after emergencies. Using the COVID-19 pandemic in China as a case study, focusing on the power and industry sectors, we find that over 40% regions exhibit strong resilience (> 0.9). Average in-resilience (0.764 and 0.783) is higher than post-resilience (0.534 and 0.598) in both sectors, indicating lower resilience during than after emergencies. Significant differences in resilience performance exist across regions, with Hebei (0.93) and Hangzhou (0.92) as top performers, and Qinghai (0.29) and Guiyang (0.36) as the least resilient. Furthermore, a preliminary correlation analysis identifies 22 factors affecting carbon resilience; higher energy consumption, stronger industrial production, and a healthier regional economy positively contribute to resilience with coefficients over + 0.3, while pandemic severity negatively impacts resilience, with coefficients up to -0.58. These findings provide valuable references for policymaking to achieve carbon neutrality goals.

Evaluation of the COVID-19 vaccine effectiveness on the outcomes of COVID 19 disease in Iran: a test-negative case-control study.

Introduction: This study measures the COVID-19 vaccine effectiveness (CVE) against hospital admission and severe COVID-19. Methods: This study is a test-negative case-control design using data from eight provinces in April, 2021 until March, 2022. The individuals were classified as cases and controls based on the results of the RT-PCR test for SARS-CoV-2 and matched based on the timing of the test being conducted as well as the timing of hospital admission. The measure of association was an odds ratio (OR) by univariate and multiple logistic regression. The multiple logistic regression has been carried out to take confounding factors and potential effect modifiers into account. The CVE was computed as CVE = (1 - OR)*100 with 95% confidence interval. Results: Among 19314 admitted patients, of whom 13216 (68.4%) were cases and 6098 (31.6%) were controls, 1313 (6.8%) died. From total, 5959 (30.8%) patients had received the vaccine in which one, two, and booster doses were 2443 (12.6%), 2796 (14.5Ùª), and 720 (3.7Ùª), respectively. The estimated adjusted effectiveness of only one dose, two doses and booter vaccination were 22% (95% CI: 14%-29%), 35% (95% CI: 29%-41%) and 33% (95% CI: 16%-47%), respectively. In addition, the adjusted vaccine effectiveness against severe outcome was 33% (95% CI: 19%- 44%), 34% (95% CI: 20%- 45%) and 20% (95% CI: -29%- 50%) for those who received one, two and booster vaccinations, respectively. Conclusion: Our study concluded that full vaccination, though less effective compared to similar studies elsewhere, decreased hospital admissions and deaths from COVID-19 in Iran, particularly during the Delta variant period, with an observed decline during the Omicron variant dominance.

Risk assessment and clinical implications of COVID-19 in multiple myeloma patients: A systematic review and meta-analysis.

INTRODUCTION: Patients with multiple myeloma (MM) face heightened infection susceptibility, particularly severe risks from COVID-19. This study, the first systematic review in its domain, seeks to assess the impacts of COVID-19 on MM patients. METHOD: Adhering to PRISMA guidelines and PROSPERO registration (ID: CRD42023407784), this study conducted an exhaustive literature search from January 1, 2020, to April 12, 2024, using specified search terms in major databases (PubMed, EMBASE, and Web of Science). Quality assessment utilized the JBI Critical checklist, while publication bias was assessed using Egger's test and funnel plot. The leave-one-out sensitivity analyses were performed to assess the robustness of the results by excluding one study at a time to identify studies with a high risk of bias or those that significantly influenced the overall effect size. Data synthesis involved fitting a random-effects model and estimating meta-regression coefficients. RESULTS: A total of 14 studies, encompassing a sample size of 3214 yielded pooled estimates indicating a hospitalization rate of 53% (95% CI: 40.81, 65.93) with considerable heterogeneity across studies (I2 = 99%). The ICU admission rate was 17% (95% CI: 11.74, 21.37), also with significant heterogeneity (I2 = 94%). The pooled mortality rate was 22% (95% CI: 15.33, 28.93), showing high heterogeneity (I2 = 97%). The pooled survival rate stood at 78% (95% CI: 71.07, 84.67), again exhibiting substantial heterogeneity (I2 = 97%). Subgroup analysis and meta-regression highlighted that study types, demographic factors, and patient comorbidities significantly contributed to the observed outcome heterogeneity, revealing distinct patterns. Mortality rates increased by 15% for participants with a median age above 67 years. ICU admission rates were positively correlated with obesity, with a 20% increase for groups with at least 19% obesity. Mortality rates rose by 33% for the group of patients with at least 19% obesity, while survival rates decreased by 33% in the same group. CONCLUSION: Our meta-analysis sheds light on diverse COVID-19 outcomes in multiple myeloma. Heterogeneity underscores complexities, and study types, demographics, and co-morbidities significantly influence results, emphasizing the nuanced interplay of factors.

[Multiplex analysis of post-Covid cardiorenal complications in patients with type 1 and type 2 diabetes mellitus according to the mobile diagnostic and treatment center (Diamobil)].

BACKGROUND: Patients with diabetes mellitus (DM) are at risk for a higher incidence and severity of COVID-19, as well as its adverse outcomes, including post-Covid syndrome. AIM: to assess the incidence of cardiorenal complications in patients with type 1 and type 2 diabetes (T1DM/T2DM) who have had COVID-19, and to analyze the structure and severity of disorders according to examination data at the Diamobil mobile medical diagnostic and treatment center. MATERIALS AND METHODS: a cohort of T1DM and T2DM patients examined in Diamobil (n=318), with a confirmed anamnesis of COVID-19 (n=236). The time interval between COVID-19 and the visit to Diamobil was 8.7/8.2 months for T1DM/T2DM. The parameters of the last visit before COVID-19 recorded in the Federal Register of Diabetes (FRD) were used as initial data. RESULTS: Clinical characteristics of patients with T1DM/T2DM: age - 49.2/64.5 years, duration of DM - 22/11 years, proportion of women - 64/73%, respectively. After analysis the data from visits before and after COVID-19 there weren't statistically significant differences in HbA1c levels for both types of DM (before 9.0/8.3%; after 8.4/8.2%, respectively), there was the intensification of glucose lowering therapy (the proportion of patients with T2DM on 2 and 3 component therapy increased by 4.3% and 1.6%, the proportion of patients on insulin therapy by 16%). After COVID-19, there was a statistically significant decrease in glomerular filtration rate (GFR) in T1DM from 88.1 to 62 ml/min/1.73 m2; with T2DM from 74.7 to 54.1 ml/min/1.73 m2. When assessing acute diabetic complications, there was an increase in the frequency of coma in T1DM by 1.5 times, severe hypoglycemia in T1DM by 3 times, and in T2DM by 1.7 times. Analysis of the frequency of cardiorenal complications before and after COVID-19 showed a total increase of 8.5% in T1DM, by 13.2% in T2DM, of which myocardial infarction, ischemic heart disease, and CHF increased in T1DM in the range from 1.5 to 5 times, with T2DM by 1.3 times, the frequency of CKD with T1DM by 1.5 times, with T2DM by 5.6 times. CONCLUSION: There was a decline of kidney filtration function (decrease in GFR) and an increase in the frequency of cardiovascular complications in both types of diabetes in post-Covid period while patients achieved a stable HbA1c levels by intensifying therapy during the COVID-19 infection. This fact reflects combined damage to the kidney and cardiovascular system as a part of the post-Covid syndrome and determines a key set of measures for the development of preventive strategies.

Acceptance of SARS-CoV-2 Surveillance Testing Among Patients Receiving Dialysis: A Cluster Randomized Trial.

Importance: Integrating routine SARS-CoV-2 testing in dialysis facilities may benefit patients receiving dialysis by mitigating risks of serious illness and reducing transmission. Patient acceptance of nonmandatory testing is unknown. Objective: To evaluate the acceptance of 2 SARS-CoV-2 testing strategies among patients in hemodialysis facilities nationwide. Design, Setting, and Participants: This nationwide cluster (dialysis facility-level) randomized trial investigated the acceptance of SARS-CoV-2 testing among patients receiving maintenance hemodialysis at facilities located in 22 states. Intervention: Anterior nares real-time reverse transcriptase-polymerase chain reaction tests offered once every 2 weeks (static testing facilities) vs offered once a week, once every 2 weeks, or once a month depending on county COVID-19 infection prevalence (dynamic testing facilities). Facilities were randomized by county, and tests were offered for 3 months between February 4 and July 24, 2023. Main Outcomes and Measures: The primary outcome was test acceptance. Secondary outcomes included the proportion of patients who accepted at least 1 test. Results: In total, 62 hemodialysis facilities were randomized and 57 participated. Among 2389 participating patients, the median age was 64 (IQR, 54-74) years, 1341 (56%) were male, 138 (6%) were categorized as American Indian, 60 (3%) Asian, 885 (37%) Black, 75 (3%) Native Hawaiian or Pacific Islander, 338 (14%) Hispanic, and 876 (37%) White; and 1603 (67%) had diabetes. A median of 6 (IQR, 6-6) tests were offered per patient in the static arm and 4 (3-6) tests in the dynamic arm. Test acceptance was low: 8% of offered tests were accepted in each of the test arms. Among 503 patients who accepted at least 1 test, the median percentage of offered tests that were accepted was 16% (IQR, 17%-42%) using the static testing strategy and 50% (IQR, 33%-75%) using the dynamic testing strategy (P < .001). Older patients (odds ratio [OR], 1.08 [95% CI, 1.01-1.16] per 5-year age increment), patients with (vs without) diabetes (OR, 1.59 [95% CI, 1.18-2.16]), and women compared with men (OR, 1.30 [95% CI, 0.98-1.73]) were more likely to accept multiple tests. Patients designated in the electronic health record as Hispanic were more likely than patients designated as White (OR, 1.78 [95% CI, 1.15-2.76]) to accept at least 1 test, whereas patients living in zip codes electing Republican representatives to Congress were less likely than patients living in zip codes electing Democratic representatives (OR, 0.34 [95% CI, 0.17-0.69]) to accept multiple tests. Conclusions and Relevance: In this cluster randomized trial evaluating 2 SARS-CoV-2 testing strategies in dialysis facilities, test acceptance was low, and a dynamic testing strategy anchored to COVID-19 infection prevalence did not outperform a static testing strategy of every 2 weeks.

Individual use of self-medication and other remedies in COVID-19 outpatients in Western-Pomerania.

We analyzed data from positively tested COVID-19 outpatients to describe self-medication with OTC drugs and use of other remedies against symptoms of SARS-CoV-2 infection. We specifically considered their type and frequency, as well as associations with patient characteristics, and reasons for use. Data were collected between May 1, 2020 and February 22, 2021 with two questionnaires in an observational cohort study with PCR-confirmed SARS-CoV-2-positive adult outpatients in the district of Western Pomerania in Germany. 523 out of 710 outpatients (74%; 340 women and 183 men) reported using drugs and other remedies to relieve COVID-19-symptoms. Overall, participants reported utilization of 1282 finished dosage products or remedies, including 213 different ingredients. In the population of 710 outpatients, utilization of ibuprofen (26%), acetaminophen (21%), metamizole (14%), and acetylsalicylic acid (10%) was most commonly reported. Phytopharmaceuticals, herbal and animal products as well as vitamins and minerals were also frequently reported. Among the 523 participants who used drugs and other remedies, most commonly mentioned reasons for use were headache (40%), other kinds of pain (e.g. myalgia; 37%), fever (24%) and cough (16%). Our analysis showed that a majority of the participants tried to alleviate COVID-19-symptoms using drugs and other remedies. Especially analgesic and antipyretic agents, followed by herbal medicines, were used very frequently.Trial registration: German Register for Clinical Studies DRKS00021672, first registration on December 1st, 2020.

Variant-specific antibody profiling for tracking SARS-CoV-2 variant infections in children and adolescents.

Monitoring the seroprevalence of SARS-CoV-2 in children and adolescents can provide valuable information for effective SARS-CoV-2 surveillance, and thus guide vaccination strategies. In this study, we quantified antibodies against the spike S1 domains of several SARS-CoV-2 variants (wild-type, Alpha, Delta, and Omicron variants) as well as endemic human coronaviruses (HCoVs) in 1,309 children and adolescents screened between December 2020 and March 2023. Their antibody binding profiles were compared with those of 22 pre-pandemic samples from children and adolescents using an in-house Luminex®-based Corona Array (CA). The primary objectives of this study were to (i) monitor SARS-CoV-2-specific antibodies in children and adolescents, (ii) evaluate whether the S1-specific antibody response can identify the infecting variant of concern (VoC), (iii) estimate the prevalence of silent infections, and (iv) test whether vaccination or infection with SARS-CoV-2 induce HCoV cross-reactive antibodies. Both SARS-CoV-2 infection and vaccination induced a robust antibody response against the S1 domain of WT and VoCs in children and adolescents. Antibodies specific for the S1 domain were able to distinguish between SARS-CoV-2 VoCs in infected children. The serologically identified VoC was typically the predominant VoC at the time of infection. Furthermore, our highly sensitive CA identified more silent SARS-CoV-2 infections than a commercial ELISA (12.1% vs. 6.3%, respectively), and provided insights into the infecting VoC. Seroconversion to endemic HCoVs occurred in early childhood, and vaccination or infection with SARS-CoV-2 did not induce HCoV S1 cross-reactive antibodies. In conclusion, the antibody response to the S1 domain of the spike protein of SARS-CoV-2 is highly specific, providing information about the infecting VoC and revealing clinically silent infections.

Different polarization and functionality of CD4+ T helper subsets in people with post-COVID condition.

Introduction: After mild COVID-19 that does not require hospitalization, some individuals develop persistent symptoms that may worsen over time, producing a multisystemic condition termed Post-COVID condition (PCC). Among other disorders, PCC is characterized by persistent changes in the immune system that may not be solved several months after COVID-19 diagnosis. Methods: People with PCC were recruited to determine the distribution and functionality of CD4+ T helper (Th) subsets in comparison with individuals with mild, severe, and critical presentations of acute COVID-19 to evaluate their contribution as risk or protective factors for PCC. Results: People with PCC showed low levels of Th1 cells, similar to individuals with severe and critical COVID-19, although these cells presented a higher capacity to express IFNγ in response to stimulation. Th2/Th1 correlation was negative in individuals with acute forms of COVID-19, but there was no significant Th2/Th1 correlation in people with PCC. Th2 cells from people with PCC presented high capacity to express IL-4 and IL-13, which are related to low ventilation and death associated with COVID-19. Levels of proinflammatory Th9 and Th17 subsets were significantly higher in people with PCC in comparison with acute COVID-19, being Th1/Th9 correlation negative in these individuals, which probably contributed to a more pro-inflammatory than antiviral scenario. Th17 cells from approximately 50% of individuals with PCC had no capacity to express IL-17A and IL-22, similar to individuals with critical COVID-19, which would prevent clearing extracellular pathogens. Th2/Th17 correlation was positive in people with PCC, which in the absence of negative Th1/Th2 correlation could also contribute to the proinflammatory state. Finally, Th22 cells from most individuals with PCC had no capacity to express IL-13 or IL-22, which could increase tendency to reinfections due to impaired epithelial regeneration. Discussion: People with PCC showed skewed polarization of CD4+ Th subsets with altered functionality that was more similar to individuals with severe and critical presentations of acute COVID-19 than to people who fully recovered from mild disease. New strategies aimed at reprogramming the immune response and redirecting CD4+ Th cell polarization may be necessary to reduce the proinflammatory environment characteristic of PCC.

Getting breastfeeding started under pandemic visiting restrictions: lessons learned in Germany.

BACKGROUND: The COVID-19 pandemic contact restrictions considerably changed maternal visiting contacts during the time in which breastfeeding is initiated. We wanted to know how maternity ward staff and mothers rated the conditions of starting breastfeeding under contact restrictions. METHODS: In the Breastfeeding in North Rhine-Westphalia (SINA) study, Germany, 2021/22, chief physicians as well as ward staff from 41 (out of 131) maternity hospitals (82 members of the healthcare sector in total) were surveyed by telephone concerning structural and practical conditions for breastfeeding support before and during the pandemic; 192 (out of 426 eligible) mothers answered an online-questionnaire about their breastfeeding experiences at 2 weeks and 2 months after birth. RESULTS: In almost all of the hospitals, visits were restricted due to the pandemic, with the exception of the primary support person. After more than one year of pandemic experience, the ward staff were convinced that the restrictions were mostly positive for the mothers (97.6%) and for the ward staff themselves (78.0%). A total of 80.5% of the ward staff would maintain the restrictions beyond the pandemic. The mothers themselves mostly rated the restrictions in the hospital as being just right; moreover, many mothers voluntarily maintained the restrictions at home, at least in part. CONCLUSIONS: The unprecedented visiting restrictions in hospitals during the pandemic were like an "experiment" born out of necessity. Restricting visiting arrangements may be an underestimated beneficial component for the development of the mother-infant dyad in perinatal breastfeeding care, particularly in healthcare systems where almost all births occur in the maternity hospital.

The Comparative Full-Length Genome Characterization of African Swine Fever Virus Detected in Thailand.

African swine fever virus (ASFV) has been responsible for the globally devastating epidemics in wild and domesticated pigs. Of the 24 identified ASFV genotypes, genotype II is the primary cause for the pandemic occurring in Europe and Asia since its emergence in Georgia in 2007. The current study aimed to characterize the full-length genomic pattern of the ASFV strain from Thailand, TH1_22/CR (Accession No. PP915735), which was then compared with genomic diversity across other Asian isolates using Georgia 2007/1 (Accession No. FR682468) as the reference. Viral DNA was isolated from the pig spleen sample following library preparation and paired-end sequencing using the MiSeq Illumina platform. The sequenced TH1_22/CR isolate spanned 189,395 nucleotides encoding 193 open reading frames (ORFs), exhibiting maximum nucleotide similarity (99.99%) with Georgian (Georgia 2007/1) and Chinese (Wuhan 2019-1 and China HLJ) isolates. Based on phylogenetic analysis, the TH1_22/CR isolate (Accession No. PP915735) was characterized as genotype II, serogroup 8, and IGR-II due to the presence of three tandem repeat sequences (TRSs). Genetic variations including SNPs and single and polynucleotide indels were identified in TH1_22/CR in agreement with other Asian isolates. For comprehensive analysis, the genome was divided into four regions (I-IV) based on gene location. Overall, the TH1_22/CR isolate demonstrated eight SNPs and indels in its genome. Two unique SNPs were reported in the coding regions of the TH1_22/CR isolate, out of which, a C-591-T substitution was seen in MGF 360-4L and a C-297-T was found in A238L, and four unique SNPs were reported in non-coding regions (NCRs). Furthermore, a 29 bp deletion was observed in the IGR between MGF 110-13La and MGF 110-13Lb, as well as 52 bp deletion in the ASFV G ACD 00350 gene. This comparative analysis establishes the foundational information for future studies on the diversity and phylogeography of this regionally significant genetic sub-group of ASFV.

A national survey of current rehabilitation service provisions for people living with chronic kidney disease in the UK: implications for policy and practice.

BACKGROUND: National guidance recognises the key role of rehabilitation in improving outcomes for people living with chronic kidney disease. Implementation of this guidance is reliant upon an adequate and skilled rehabilitation workforce. Data relating to this is currently lacking within the UK. This survey aimed to identify variations and good practices in kidney physiotherapy (PT), occupational therapy (OT) and clinical exercise physiologist (CEP) provision; and to understand barriers to implementation. METHODS: An online survey was sent to all 87 UK kidney units between June 2022 and January 2023. Data was collected on the provision of therapy services, barriers to service provision and responses to the COVID-19 pandemic. The quantitative survey was analysed using descriptive statistics. Free-text responses were explored using reflexive thematic analysis. RESULTS: Forty-five units (52%) responded. Seventeen (38%) units reported having a PT and 15 (33%) an OT with a specialist kidney role; one unit (7%) had access to a CEP. Thirty units (67%) offered inpatient therapy services, ten (22%) outpatient therapy clinics, six (13%) intradialytic exercise, six (13%) symptom management and three (7%) outpatient rehabilitation. Qualitative data revealed lack of money/funding and time (both n = 35, 85% and n = 34, 83% respectively) were the main barriers to delivering kidney-specific therapy. Responders saw an increase in the complexity of their caseload, a reduction in staffing levels and consequently, service provision during the COVID-19 pandemic. Exemplars of innovative service delivery, including hybrid digital and remote services, were viewed as positive responses to the COVID-19 pandemic. CONCLUSION: Despite clear evidence of the benefits of rehabilitation, across the UK, there remains limited and variable access to kidney-specific therapy services. Equitable access to kidney-specific rehabilitation services is urgently required to support people to 'live well' with kidney disease.

"I couldn't say goodbye": Thematic analysis of interviews with bereaved relatives who lost their loved ones during the COVID-19 pandemic.

BACKGROUND: Delivering serious news is usually challenging for healthcare professionals and the pandemic of COVID-19 and related restrictions brought additional challenges in this process. AIMS: To explore the experience of bereaved relatives with receiving serious news from healthcare professionals during the pandemic COVID-19. DESIGN: A qualitative study using thematic analysis and a codebook approach of data collected in semi-structured interviews with bereaved relatives. SETTING/PARTICIPANTS: Data were collected from July to August 2022 in person/via phone with bereaved relatives who lost their relatives during the pandemic (from March 2020 to March 2022). Participants were recruited using a convenience sample and snowball method through social media and through one university hospital palliative care unit that invited bereaved relatives of deceased patients treated at the unit to participate in this study. RESULTS: A total of 22 participants, consisting of 4 men and 18 women, were interviewed for this study. Most of the participants were sons or daughters of individuals who had died (5 grandchildren, 14 sons/daughters, 2 spouses, 1 great-niece). Six themes were identified: Burden caused by visit ban, Fear of COVID-19, Inappropriate behaviour and communication of healthcare professionals, High need for emotional support, Need for detailed and honest communication, Tendency to make excuses for mistakes and lapses by healthcare professionals. CONCLUSIONS: Delivering serious news during a pandemic was negatively influenced by a lack of contact with patients and a lack of support and empathetic communication with staff. Overcoming these circumstances can be achieved by frequent communication using various communication tools (such as videoconferences or phone calls), and maintaining empathy and honesty in the communication process.
