Integrated Genomic and Social Network Analyses of SARS-CoV-2 Transmission in the Healthcare Setting.

BACKGROUND: Infection prevention (IP) measures are designed to mitigate the transmission of pathogens in healthcare. Using large-scale viral genomic and social network analyses, we determined if IP measures used during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic were adequate in protecting healthcare workers (HCWs) and patients from acquiring SARS-CoV-2. METHODS: We performed retrospective cross-sectional analyses of viral genomics from all available SARS-CoV-2 viral samples collected at UC San Diego Health and social network analysis using the electronic medical record to derive temporospatial overlap of infections among related viromes and supplemented with contact tracing data. The outcome measure was any instance of healthcare transmission, defined as cases with closely related viral genomes and epidemiological connection within the healthcare setting during the infection window. Between November 2020 through January 2022, 12 933 viral genomes were obtained from 35 666 patients and HCWs. RESULTS: Among 5112 SARS-CoV-2 viral samples sequenced from the second and third waves of SARS-CoV-2 (pre-Omicron), 291 pairs were derived from persons with a plausible healthcare overlap. Of these, 34 pairs (12%) were phylogenetically linked: 19 attributable to household and 14 to healthcare transmission. During the Omicron wave, 2106 contact pairs among 7821 sequences resulted in 120 (6%) related pairs among 32 clusters, of which 10 were consistent with healthcare transmission. Transmission was more likely to occur in shared spaces in the older hospital compared with the newer hospital (2.54 vs 0.63 transmission events per 1000 admissions, P < .001). CONCLUSIONS: IP strategies were effective at identifying and preventing healthcare SARS-CoV-2 transmission.

Inpatient treatment of acute diverticulitis between 2010 and 2021 - A German nationwide study about long-term trends and effects of the SARS-CoV-2 pandemic.

AIM: The aims of this study were to analyse all hospitalizations for acute diverticulitis in Germany from 2010 to 2021 and to assess the effects of the first 2 years of the SARS-CoV-2 pandemic on hospitalizations for acute diverticulitis. METHOD: Using data from the German Federal Statistical Office, we analysed fully anonymized healthcare data of hospitalizations and treatment regimens with acute diverticulitis as the main diagnosis between 2010 and 2021. Logistic regression analyses for in-hospital mortality were performed. RESULTS: A total of 608,162 hospitalizations were included. While the number of hospitalizations constantly increased until 2019 (+52.4%), a relative decrease of 10.1% was observed between 2019 and 2020, followed by stable numbers of hospitalizations in 2021 (+1.1% compared with 2020). In-hospital mortality showed a relative decrease of 33.2% until 2019 and thereafter a relative increase of 26.9% in 2020 and of 7.5% in 2021. A 21.6% and a 19.3% drop in hospitalizations was observed during the first and second waves of the SARS-CoV-2 pandemic, mostly affecting hospitalizations for uncomplicated diverticulitis, with a corresponding 11.6% and 16.8% increase in admissions for complicated diverticulitis. Multivariable logistic regression analyses showed significantly higher in-hospital mortality for hospitalizations in which surgery (OR = 2.76) and CT (OR = 1.32) were given, as well as lower mortality for women (OR = 0.88), whereas percutaneous drainage was not associated with higher in-hospital mortality compared with conservative treatment (OR = 0.71). CONCLUSION: This study points out the long-term trends in inpatient treatment for acute diverticulitis and the in-hospital mortality risk factors of patients hospitalized for acute diverticulitis in a large nationwide cohort, as well as changes in these trends and factors resulting from the SARS-CoV-2 pandemic. These changes might be attributable to delayed diagnosis and thus more severe stages of disease as a result of containment measures.

Evaluation of masks and mask material suitability for bioaerosol capture.

Non-medical masks such as disposable non-medical, commercially produced cloth, and homemade masks are not regulated like surgical masks. Their performance, in terms of filtration efficiency and breathability, is variable and unreliable. This research provides a quantitative evaluation of various non-medical masks, assesses their fabrics' potential for the reduction of transmission of bioaerosols such as the SARS-CoV-2 virus, and compares them to surgical masks and N95 filtering facepiece respirators. Using a testing line with a NaCl challenge aerosol, four types of commercial reusable cloth masks, two types of disposable non-medical masks, three types of surgical or N95 masks, and seven types of commonly available materials were tested individually and in combinations. The testing line and procedure were adapted from the ASTM F2299-03: Standard Test Method for Determining the Initial Efficiency of Materials Used in Medical Face Masks to Penetration by Particulates Using Latex Spheres testing method used for testing surgical masks. Filtration efficiencies at 0.15 µm particle diameter at a face velocity of 25 cm/sec for commercial cloth masks, disposable non-medical masks, surgical masks, commercial mask combinations, and homemade combinations ranged from 16-29%, 39-76%, 91-97%, 51-95%, and 45-94%, respectively. The pressure drop results for the different masks and material combinations were all under 3 mm H2O/cm2 except for one material configuration. This study builds on other research that looks at individual materials and masks by testing combinations alongside the individual masks and materials. With proper layering, household materials can achieve the filtration efficiency and low pressure drop requirements of surgical masks. The filtration capabilities of disposable and cloth mask fabrics vary considerably meaning that they are not a reliable or consistent facemask option, regardless of fit.

Effects of the COVID-19 Pandemic on Everyday Neurosurgical Practice in Alsace, France: Lessons Learned, Current Perspectives, and Future Challenges-Preliminary Results of a Longitudinal Multicentric Study Registry.

Background and Objectives: The global outbreak caused by the SARS-CoV-2 pandemic disrupted healthcare worldwide, impacting the organization of intensive care units and surgical care units. This study aimed to document the daily neurosurgical activity in Alsace, France, one of the European epicenters of the pandemic, and provide evidence of the adaptive strategies deployed during such a critical time for healthcare services. Materials and Methods: The multicentric longitudinal study was based on a prospective cohort of patients requiring neurosurgical care in the Neurosurgical Departments of Alsace, France, between March 2020 and March 2022. Surgical activity was compared with pre-pandemic performances through data obtained from electronic patient records. Results: A total of 3842 patients benefited from care in a neurosurgical unit during the period of interest; 2352 of them underwent surgeries with a wide range of pathologies treated. Surgeries were initially limited to neurosurgical emergencies only, then urgent cases were slowly reinstated; however, a significant drop in surgical volume and case mix was noticed during lockdown (March-May 2020). The crisis continued to impact surgical activity until March 2022; functional procedures were postponed, though some spine surgeries could progressively be performed starting in October 2021. Various social factors, such as increased alcohol consumption during the pandemic, influenced the severity of traumatic pathologies. The progressive return to the usual profile of surgical activity was characterized by a rebound of oncological interventions. Deferrable procedures for elective spinal and functional pathologies were the most affected, with unexpected medical and social impacts. Conclusions: The task shifting and task sharing approaches implemented during the first wave of the pandemic supported the reorganization of neurosurgical care in its aftermath and enabled the safe and timely execution of a broad spectrum of surgeries. Despite the substantial disruption to routine practices, marked by a significant reduction in elective surgical volumes, comprehensive records demonstrate the successful management of the full range of neurosurgical pathologies. This underscores the efficacy of adaptive strategies in navigating the challenges imposed by the largest healthcare crisis in recent history. Those lessons will continue to provide valuable insights and guidance for health and care managers to prepare for future unpredictable scenarios.

Treatment of acute mesenteric ischemia between 2010 and 2020 - a German nation-wide study.

BACKGROUND: Aim of this study was to analyze long-term trends of hospitalizations, treatment regimen and in-hospital mortality of in-patients with acute mesenteric ischemia (AMI) over the past decade and effects of the SARS-CoV2-pandemic. METHODS: We analyzed fully anonymized data from the German Federal Statistical Office of patients with AMI between 2010 and 2020. Besides descriptive analyses of age, gender, in-hospital mortality, comorbidity burden and treatment regimen, multivariable logistic regression analyses were performed to identify independent variables associated with in-hospital mortality and different treatment. RESULTS: A total of 278,121 hospitalizations (120,667 male [43.4%], mean age 72.1 years) with AMI were included in this study. The total number of hospitalizations increased from 2010 (n = 24,172) to 2019 (n = 26,684) (relative increase 10.4%). In-hospital mortality decreased over the past decade from 36.6% to 2010 to 31.1% in 2019 (rel. decrease 15.2%). Independent risk factors for in-hospital mortality were older age (OR = 1.03 per year), higher comorbidity burden (OR = 1.06 per point in van Walraven score [vWs]), male gender (OR = 1.07), AMI as a secondary diagnosis (OR = 1.44), and the need for surgical (visceral surgery: OR = 1.38, vascular surgery: OR = 3.33) and endovascular treatment (OR = 1.21). We report a decline in hospitalizations during the first wave of infection in spring 2020 (rel. decrease 9.7%). CONCLUSION: In-hospital mortality rate has declined over the past decade, but remains high at above 30%. Older age, increased comorbidity and male gender are independent factors for in-hospital mortality. Hospitalizations requiring vascular surgery are associated with high in-hospital mortality, followed by visceral surgery and endovascular approaches. The first wave of the SARS-CoV2-pandemic in spring 2020 implied a decrease in hospital admissions.

SARS-CoV-2 elicits non-sterilizing immunity and evades vaccine-induced immunity: implications for future vaccination strategies.

Neither vaccination nor natural infection result in long-lasting protection against SARS-COV-2 infection and transmission, but both reduce the risk of severe COVID-19. To generate insights into optimal vaccination strategies for prevention of severe COVID-19 in the population, we extended a Susceptible-Exposed-Infectious-Removed (SEIR) mathematical model to compare the impact of vaccines that are highly protective against severe COVID-19 but not against infection and transmission, with those that block SARS-CoV-2 infection. Our analysis shows that vaccination strategies focusing on the prevention of severe COVID-19 are more effective than those focusing on creating of herd immunity. Key uncertainties that would affect the choice of vaccination strategies are: (1) the duration of protection against severe disease, (2) the protection against severe disease from variants that escape vaccine-induced immunity, (3) the incidence of long-COVID and level of protection provided by the vaccine, and (4) the rate of serious adverse events following vaccination, stratified by demographic variables.

Living with epilepsy during COVID-19 pandemic restrictions: A longitudinal perspective.

The purpose of our study was to explore how people with epilepsy fared during two of the most stringent 4-month society-wide COVID-19-related pandemic restrictions in Ireland, in 2020 and one year later in 2021. This was in the context of their seizure control, lifestyle factors, and access to epilepsy-related healthcare services. A 14-part questionnaire was administered to adults with epilepsy during virtual specialist epilepsy clinics in a University Hospital in Dublin, Ireland at the end of the two lockdowns. People with epilepsy were questioned on their epilepsy control, lifestyle factors, and quality of epilepsy-related medical care, compared to pre-COVID times. The study sample consisted of two separate cohorts of those diagnosed with epilepsy (100 (51.8%) in 2020, and 93 (48.2%) in 2021, with similar baseline characteristics. There was no significant change in seizure control or lifestyle factors from 2020 to 2021, except for deterioration in anti-seizure medication (ASM) adherence in 2021 compared to 2020 (p = 0.028). There was no correlation between ASM adherence and other lifestyle factors. Over the two years, poor seizure control was significantly associated with poor sleep (p < 0.001) and average seizure frequency in a month (p = 0.007). We concluded that there was no significant difference between seizure control or lifestyle factors between the two most stringent lockdowns in Ireland, in 2020 and 2021. Furthermore, people with epilepsy reported that throughout the lockdowns access to services was well maintained, and they felt well supported by their services. Contrary to the popular opinion that COVID lockdowns greatly affected patients with chronic diseases, we found that those with epilepsy attending our service remained largely stable, optimistic, and healthy during this time.

Reflective, pragmatic, and reactive decision-making by maternity service providers during the SARS-CoV-2 pandemic health system shock: a qualitative, grounded theory analysis.

BACKGROUND: Pregnant and postpartum women were identified as having particular vulnerability to severe symptomatology of SARS-CoV-2 infection, so maternity services significantly reconfigured their care provision. We examined the experiences and perceptions of maternity care staff who provided care during the pandemic in South London, United Kingdom - a region of high ethnic diversity with varied levels of social complexity. METHODS: We conducted a qualitative interview study, as part of a service evaluation between August and November 2020, using in-depth, semi-structured interviews with a range of staff (N = 29) working in maternity services. Data were analysed using Grounded Theory analysis appropriate to cross-disciplinary health research. ANALYSIS & FINDINGS: Maternity healthcare professionals provided their views, experiences, and perceptions of delivering care during the pandemic. Analysis rendered three emergent themes regarding decision-making during reconfigured maternity service provision, organised into pathways: 1) 'Reflective decision-making'; 2) 'Pragmatic decision-making'; and 3) 'Reactive decision-making'. Whilst pragmatic decision-making was found to disrupt care, reactive-decision-making was perceived to devalue the care offered and provided. Alternatively, reflective decision-making, despite the difficult working conditions of the pandemic, was seen to benefit services, with regards to care of high-quality, sustainability of staff, and innovation within the service. CONCLUSIONS: Decision-making within maternity care was found to take three forms - where at best changes to services could be innovative, at worst they could cause devaluation in care being delivered, and more often than not, these changes were disruptive. With regard to positive changes, healthcare providers identified staff empowerment, flexible working patterns (both for themselves and collectively as teams), personalised care delivery, and change-making in general, as key areas to capitalise on current and ongoing innovations borne out of the pandemic. Key learnings included a focus on care-related, meaningful listening and engagement of staff at all levels, in order to drive forward high-quality care and avoid care disruption and devaluation.

A Pandemic Lesson for Global Lung Diseases: Exacerbations Are Preventable.

A dramatic global reduction in the incidence of common seasonal respiratory viral infections has resulted from measures to limit the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the pandemic. This has been accompanied by falls reaching 50% internationally in the incidence of acute exacerbations of preexisting chronic respiratory diseases that include asthma, chronic obstructive pulmonary disease, and cystic fibrosis. At the same time, the incidence of acute bacterial pneumonia and sepsis has fallen steeply worldwide. Such findings demonstrate the profound impact of common respiratory viruses on the course of these global illnesses. Reduced transmission of common respiratory bacterial pathogens and their interactions with viruses appear also as central factors. This review summarizes pandemic changes in exacerbation rates of asthma, chronic obstructive pulmonary disease, cystic fibrosis, and pneumonia. We draw attention to the substantial body of knowledge about respiratory virus infections in these conditions, and that it has not yet translated into clinical practice. Now that the large scale of benefits that could be gained by managing these pathogens is unmistakable, we suggest that the field merits substantial academic and industrial investment. We consider how pandemic-inspired measures for prevention and treatment of common infections should become a cornerstone for managing respiratory diseases.

Use of inhaled corticosteroids in preschool children and variability among pediatricians: a real-world analysis before and during the SARS-CoV-2 pandemic.

BACKGROUND: In Italy, inhaled corticosteroids (ICSs) are inappropriately prescribed to provide relief in URTI symptoms. Extreme variation in ICS prescribing has been described at regional and sub-regional level. During 2020, extraordinary containment measures were implemented in attempt to halt Coronavirus, such as social distancing, lockdown, and the use of mask. Our objectives were to evaluate the indirect impact of the SARS-CoV-2 pandemic on prescribing patterns of ICSs in preschool children and to estimate the prescribing variability among pediatricians before and during the pandemic. METHODS: In this real-world study, we enrolled all children residing in the Lazio region (Italy), aged 5 years or less during the period 2017-2020. The main outcome measures were the annual ICS prescription prevalence, and the variability in ICS prescribing, for each study year. Variability was expressed as Median Odds Ratios (MORs). If the MOR is 1.00, there is no variation between clusters (e.g., pediatricians). If there is considerable between-cluster variation, the MOR will be large. RESULTS: The study population consisted of 210,996 children, cared by 738 pediatricians located in the 46 local health districts (LHDs). Before the pandemic, the percentage of children exposed to ICS was almost stable, ranging from 27.3 to 29.1%. During the SARS-CoV-2 pandemic, the ICS prescription prevalence dropped to 17.0% (p < 0.001). In each study year, a relevant (p < 0.001) variability was detected among both LHDs and pediatricians working in the same LHD. However, the variability among individual pediatricians was always higher. In 2020, the MOR among pediatricians was 1.77 (95% CI: 1.71-1.83) whereas the MOR among LHDs was 1.29 (1.21-1.40). Furthermore, MORs remained stable over time, and no differences were detected in ICS prescription variability before and after pandemic outbreak. CONCLUSIONS: If on one hand the SARS-CoV-2 pandemic indirectly caused the reduction in ICS prescriptions, on the other the variability in ICS prescribing habits among both LHDs and pediatricians remained stable over the whole study time span (2017-2020), showing no differences between pre- pandemic and pandemic periods. The intra-regional drug prescribing variability underlines the lack of shared guidelines for appropriate ICS therapy in preschool children, and raises equity issues in access to optimal care.

Unusual local epidemic of paediatric respiratory syncytial virus during a time of global pandemic.

BACKGROUND: Western Australia (WA) public health measures to eradicate SARS-CoV-2 resulted in a secondary reduction in paediatric respiratory syncytial virus (RSV) admissions. Following an absent expected 2020 winter peak, RSV-positive admissions surged during the summer of 2020. AIM: This report examines the number of RSV-positive admissions and severities across 36 months to better understand this out-of-season epidemic. METHODS: A retrospective observational study was performed assessing the number and severity of RSV-related respiratory hospitalisations at a peripheral paediatric centre from March 2018 to February 2021. Data were extracted from the hospital clinical database. RESULTS: The total number of included participants was n = 294. The total number of RSV hospitalisations in SY (study year) 2018 (March 2018 to February 2019), SY 2019 (March 2019 to February 2020) and SY 2020 (March 2020 to February 2021) was 67, 98 and 129, respectively. Prior to SARS-CoV-2, RSV hospitalisations were highest during the winter months. In SY 2020, there were 0 RSV hospitalisations during winter, while 101 admissions in the following summer season. The proportion of admissions requiring respiratory support was significantly reduced in SY 2020 (34.1%) compared to SY 2018 (46.9%, P = 0.050) and SY 2019 (55.2%, P = 0.004). The median length of stay (LOS) in 2020 was 2.0 which was significantly reduced from 2018 and 2019 which was 3.0, P = 0.001; and 3.0, P < 0.001, respectively. CONCLUSION: Following a period of RSV absence, there was an unprecedented surge in admission, however, with lower severity and shorter LOS.

Comparing the COVID-19-related PTSD symptoms between psychiatric patients and healthy subjects: an observational retrospective study from Northern Italy.

COVID-19 pandemic had a great impact on mental health, both in the general population and psychiatric patients. Little is known about the difference between these two populations in perceiving the pandemic as a traumatic event. The aim of the study was to compare psychiatric patients and healthy controls (HC) in terms of change over time of post-traumatic (PTSD) symptoms. Demographic and clinical variables were collected. Impact of Event Scale Revised (IES-R) scores were registered at T1 as lockdown period (March-April 2020) and T2 as restarting (May-June 2020). Descriptive analyses and linear regression models were performed. A total of 166 outpatients and 57 HC were recruited. Time (F = 15.76; p < 0.001) and diagnosis (F = 4.94; p < 0.001) had a significant effect on the change of IES-R scores, which resulted T1 > T2 (p < 0.001), except for subjects affected by Obsessive-Compulsive Disorder (OCD). Overall, IES-R scores were < in patients than in HC (p = 0.02), particularly in the schizophrenia (SKZ) subgroup (p < 0.001). IES-R scores of subjects with personality disorders (PDs) resulted to be > HC, although not statistically significant. The lockdown period was perceived as more traumatic than the reopening phase by both groups, with the exception of OCD patients, probably because of the clinical worsening associated with the urge of control against risks of contamination. Overall, HC reported more PTSD symptoms than psychiatric patients did, particularly SKZ ones. PD patients, in contrast, may be more vulnerable to PTSD symptoms probably as a result of poor coping skills. Together with OCD patients, subjects with PDs may need closer monitoring during the different phases of the pandemic. Trial Registration: ClinicalTrials.gov Identifier: NCT04694482.

Biopolymers as green-based food packaging materials: A focus on modified and unmodified starch-based films.

The ideal food packaging materials are recyclable, biodegradable, and compostable. Starch from plant sources, such as tubers, legumes, cereals, and agro-industrial plant residues, is considered one of the most suitable biopolymers for producing biodegradable films due to its natural abundance and low cost. The chemical modification of starch makes it possible to produce films with better technological properties by changing the functional groups into starch. Using biopolymers extracted from agro-industrial waste can add value to a raw material that would otherwise be discarded. The recent COVID-19 pandemic has driven a rise in demand for single-use plastics, intensifying pressure on this already out-of-control issue. This review provides an overview of biopolymers, with a particular focus on starch, to develop sustainable materials for food packaging. This study summarizes the methods and provides a potential approach to starch modification for improving the mechanical and barrier properties of starch-based films. This review also updates some trends pointed out by the food packaging sector in the last years, considering the impacts of the COVID-19 pandemic. Perspectives to achieve more sustainable food packaging toward a more circular economy are drawn.

[How many patients with inflammatory rheumatic diseases have the technical prerequisites for video consultations and are also willing to use this to carry out visits by medical specialist visits?] / Wie viele Patienten mit entzündlich rheumatischen Erkrankungen haben die technischen Voraussetzungen für Videosprechstunden und sind bereit, fachärztliche Visiten so durchzuführen?

BACKGROUND: The currently disseminating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic and limited capacities in outpatient rheumatological care, pose questions about possible alternatives to clinical visits, also in view of the digital revolution. It is unclear whether and to what extent patients with inflammatory rheumatic diseases are willing and in a position to deal with the new media, such as video consultation. METHODS: In the middle of the pandemic in May 2020 outpatients were surveyed using a standardized questionnaire in order to document their possibilities and willingness to participate in a video consultation. The treating physicians were asked whether carrying out a video consultation was considered to be a possible and meaningful option. RESULTS: Overall, 232 patients with inflammatory rheumatic diseases were surveyed (64.7% female, average age 54.0 ± 15.2 years), seropositive (n = 58) and seronegative (n = 51) rheumatoid arthritis (RA), spondyloarthritis (SpA, n = 77) including axial SpA (axSpA) and psoriatic arthropathy (PsA) as well as collagenosis and vasculitis (CoV, n = 46). The mean duration of disease was 5.5 ± 8.2 years, whereby in 75 patients (32.3%) it was the first diagnosis. The mean disease activity (0-10, subjective patient self-estimation) was 4.7 ± 2.5. Overall, 176 patients were basically aware of the possibility to carry out video consultations (75.9%) and 166 considered that they were technically capable to participate (71.6%) but only 131 were principally willing to participate (56.5%). Logistic regression analyses showed that the willingness to participate in video consultations decreased with increasing age (ß = 0.28, p = 0.01). According to the medical estimation video consultations were thought to be principally possible for 161 patients for technical reasons (69.4%) and for 127 for medical reasons (54.7%); however, a video consultation within the framework of treatment was only considered to be meaningful by the physician for 76 patients (32.8%). CONCLUSION: Not all patients can or want to participate in video consultations and the willingness declines with increasing age. The estimation of the meaningfulness of video consultations by physicians was also limited to approximately one third of the patients surveyed. This must be taken into consideration for the future planning of video consultations.

Vaccination as a Significant Factor Influencing the Psychoemotional State of Medical Students During the Sars-Cov-2 Pandemic: An International Aspect.

Background: The rapid spread of SARS-COV-2, characterized by its severe course in the absence of effective specific treatment for this infection, may become a significant risk factor for psycho-emotional disorders' emergence during this pandemic. One of the vulnerable groups in the current situation are first-year medical students, whose problems associated with an unfavorable sanitary-epidemiological situation and an increased infection risk are compounded by the difficulties of adapting to specific professional environments. In this situation, along with strict adherence to nonspecific prevention methods, the mass student SARS-COV-2 vaccination acquires particular importance. Objective: To compare the attitudes of first-year medical students in Russia and Azerbaijan toward SARS-COV-2 immunization and to assess the vaccination impact on the student's psycho-emotional state during the SARS-COV-2 pandemic. Materials and Methods: The study involved 594 first-year students at the Moscow and Baku branches of Sechenov University. The Google Forms platform was used to conduct an anonymous sociological survey. To compare the psychoemotional state of vaccinated freshmen and non-vaccinated students, we used the State-Trait Anxiety Inventory, STAI, to assess reactive anxiety and the Beck Depression Inventory test - to diagnose depressive symptoms. The online survey was conducted during the fourth wave of coronavirus infection. WHO official sources were used to analyze the current epidemiological SARS-COV-2 situation during the study data provided by the Russian Federal Service on Customers' Rights Protection and Human Well-Being Surveillance and JHU CSSE. Statistical analysis was carried out using RStudio. Results: The study results showed that vaccination coverage of first-year students at the Moscow branch of Sechenov University during the fourth wave of the SARS-COV-2 pandemic was 42,9±5,13%, at the Baku branch - 69,6±5,86%. The lack of reliable information about anticovid vaccines, indicated by a third of all respondents, may largely determine the motivated participation in the vaccination SARS-COV-2 campaign. The role of medical school in imparting knowledge about active SARS-COV-2 immunization to medical students was found to be insignificant. It was shown that the percentage of students willing to recommend SARS-COV-2 vaccination to the people around them and thereby contribute to increasing collective immunity level significantly depends on the percentage of students vaccinated. It was proved that vaccinated students were characterized by significantly greater psychological stability regardless of their study place. Conclusion: Vaccination is not only a good preventive measure against the infection spread but also a significant factor in stabilizing the psycho-emotional state of first-year students, which significantly affects the quality of their educational process and its effectiveness.

Addressing Chronic Gynecological Diseases in the SARS-CoV-2 Pandemic.

Introduction: the COVID-19 pandemic has had a considerable impact on healthcare systems worldwide. Since the actual influence of the pandemic on gynecological care is still unclear, we aim to evaluate the effect of the SARS-CoV-2 pandemic on gynecological procedures compared to the pre-pandemic period in Romania. Materials and Methods: this is a single-center retrospective observational study, involving patients hospitalized in the year before the SARS-CoV-2 pandemic (PP), in the first year of the pandemic (P1), and in the second year of the pandemic until February 2022 (P2). The percentages of interventions were analyzed globally but also according to the type of surgery applied on the female genital organs. Results: during pandemic, the number of gynecological surgeries dropped considerably, by more than 50% in some cases, or even decreased by up to 100%, having a major impact on women's health, especially in the first year of the pandemic (P1), before slightly increasing in the post-vaccination period (PV). Surgically treated cancer cases dropped by over 80% during the pandemic, and the consequences of this will be seen in the future. Conclusions: the COVID-19 pandemic played an important part in gynecological care management in the Romanian public health care system, and the effect will have to be investigated in the future.

[Management of the Sars-Cov2 pandemic in France - Benefit-risk balance at the collective versus individual level individual scale in children]. / Gestion de la pandémie à Sars-Cov2 en France ­ Balance bénéfice-risque à l'échelle collective versus à l'échelle individuelle chez les enfants.

According to the precautionary principle and facing the initial uncertainty of the potential seriousness of Covid-19, France has adopted collective measures understood as acceptable despite the deprivation of liberty and the known risks of long confinement on mental health. Such measures should be applied proportionately and cause the least possible harm. Among these, the closure of schools was decided by declination of those appearing in response plans to viral pandemics where children play a major role in the transmission of the disease (e.g. flu). In an unprecedented way, measures and constraints have been taken against the interests of children and to protect a vulnerable group other than the children themselves. From the perspective of children's health, the relationship between health gains from these measures and negative consequences has been unbalanced. The reduction in instruction time has reduced overall academic performance and has had adverse consequences for the socialization and development of children. Confinement has generated more serious domestic accidents, an increase in intra-family violence and marked collateral effects in terms of the mental health of adolescents. Very early on, the various Covid19-related publications showed that children were not the driving force behind this pandemic - If the initial application of collective measures was legitimate, the adaptation of measures at the individual level was out of step with the already known repercussions followed by those observed on the health of the child.

Reemergence of Invasive Pneumococcal Disease in Germany During the Spring and Summer of 2021.

BACKGROUND: The incidence of invasive pneumococcal disease (IPD) decreased worldwide in 2020 and the first quarter of 2021, concurrent with nonpharmaceutical interventions (NPIs) intended to stymie transmission of SARS-CoV-2. In 2021, the stringency of these NPI strategies has varied. We investigated age- and serotype-specific variations in IPD case counts in Germany in 2020-2021. METHODS: IPD cases through 30 November 2021 were stratified by age group, serotype, or geographic location. IPD surveillance data in 2020-2021 were compared with (1) IPD surveillance data from 2015-2019, (2) mobility data during 2020 and 2021, and (3) NPI stringency data in 2020 and 2021. RESULTS: IPD incidence began to return toward baseline among children 0-4 years old in April 2021 and exceeded baseline by June 2021 (a 9% increase over the average monthly values for 2015-2019). Children aged 5-14 years and adults aged 15-34 or ≥80 years showed increases in IPD cases that exceeded baseline values starting in July 2021, with increases also starting in spring 2021. The age distribution and proportion of vaccine-serotype IPD remained comparable to those in previous years, despite lower overall case counts in 2020 and 2021. The percentage change in IPD incidence compared with the previous 5 years was correlated with changes in mobility and with NPI stringency. CONCLUSIONS: IPD levels began to return to and exceed seasonal levels in spring and summer 2021 in Germany, following sharp declines in 2020 that coincided with NPIs related to the coronavirus disease 2019 pandemic. Proportions of vaccine serotypes remained largely consistent throughout 2020-2021.

A patient with pulmonary hypertension waiting for donor lungs during the pandemic: 194 days on extracorporeal life support including 143 days on pulmonary artery to left atrium shunt.

Patients with pulmonary hypertension and end-stage lung disease are fraught with high mortality while on a waiting list for lung transplant. With sometimes rapid deterioration they may require veno-arterial extracorporeal membrane oxygenation (VA-ECMO) as an immediate life-saving technique, which is a time-limited solution. The technique of pulmonary artery to left atrium (PA-LA) shunt fitted with an oxygenator enables bridging the patient to transplant for a longer time period. This low-resistance paracorporeal pumpless lung assist device allows for de-adaptation of the right ventricle back to lower afterload before the lung transplantation is carried out. The PA-LA shunt with an oxygenator also conveys a risk of multiple complications with reported median of 10-26 days until transplant. We report a case of pulmonary capillary hemangiomatosis in a 35-year-old female who had to wait for donor lungs during the pandemic of SARS-CoV-2 for 143 days on PA-LA shunt with oxygenator following 51 days on VA-ECMO. The extremely long course associated with multiple complications including three cerebral embolisms, episodes of sepsis and ingrowth of the return cannula into the left ventricular wall gives insight into the limits of this bridging technique.

Adapting to a major crisis: Sleep and mental health during two lockdowns.

The present study aimed at investigating the impact of the pandemic on sleep and mental health in healthy individuals (n = 78) as well as in psychiatric outpatients (n = 30) during the first and the second lockdown in Germany, in March and November 2020, respectively. Sleep quality and anxiety were worse in patients compared with controls during both lockdowns. Further, patients but not controls exhibited higher levels of depression and overall psychiatric symptomatology during the second lockdown. No differences were found in the perceived threat evoked by the pandemic. The data suggest that healthy individuals adapt flexibly to the difficult situation over the time course of the pandemic, whereas psychiatric patients seem to get worse, indicating difficulties in adapting to stressful circumstances.
