Stratification of Risks of Tuberculosis Relapses during the Pandemic of the Novel Coronavirus Infection

The objective: to assess risk factors for tuberculosis relapse during the COVID-19 pandemic. Results. During the retrospective study, medical documents of patients treated for tuberculosis in 2020-2022 were analyzed. 140 patients above 18 years old with confirmed tuberculosis were included: newly diagnosed tuberculosis – 50 patients, early relapses – 50 patients, and late relapses – 40 patients. At the first stage, significant factors for relapse development were identified (ANOVA): diabetes (F=19402,8;p=0,000000), substances abuse (F=547,6;p=0,000000), alcohol abuse (F=149,7;p=0,000000), MDR MTB (F=107,8;p=0,000000), HIV infection (F=72,4;p=0,000000), imprisonment (F=49,5;p=0,000000), chronic respiratory diseases (F=47,1;p=0,000000), smoking (F=29,0;p=0,000000), and social status (F=28,9;p= 0,000000). At the second stage (cluster analysis), factors implementing the risks of development of early or late relapses were identified. As well as before the COVID-19 pandemic, social, medical and biological risk factors play a significant role in the development of tuberculosis relapses;history of COVID-19 was not one of the risk factors;and stratification of the risk factors made it possible to identify factors that contribute to development of both early and late relapses and to determine preventive measures. © 2023 New Terra Publishing House.

Investigating the impact of the covid-19 pandemic on older adolescents' psychological wellbeing and self-identified cognitive difficulties

Background The COVID-19 pandemic coincides with growing concern regarding the mental health of young people. Older adolescents have faced a particular set of pandemic-related challenges and demonstrate heightened vulnerability to affective disorders (particularly anxiety). Anxiety symptoms are associated with a range of cognitive difficulties. Older adolescents may therefore be susceptible to pandemic-related declines in wellbeing and associated cognitive difficulties. Methods At three timepoints, independent samples of young people aged 16-18 years (N = 607, 242, 618 respectively) completed an online survey. Data collection coincided with periods of lockdown (timepoints 1 and 3) and young people returning to school (timepoint 2). The survey assessed subjective impacts of the pandemic on overall wellbeing, anxiety and cognitive function. Results Findings demonstrated the detrimental impact of the COVID-19 pandemic on older adolescents' psychological wellbeing-a finding that was consistent across samples. The majority of young people at each timepoint experienced heightened anxiety. Crucially, pandemic-related anxiety was associated with self-identified cognitive difficulties, a pattern of association that was evident at all three timepoints. The nature and extent of these difficulties were predictive of specific pandemic-related concerns in this age group. Conclusions Older adolescents' experiences of the pandemic are characterised by subjective declines in wellbeing and stable patterns of association between anxiety and self-identified cognitive difficulties. Implications are discussed with reference to future research and intervention. (PsycInfo Database Record (c) 2023 APA, all rights reserved)

Assessment of long-term adverse events regarding different COVID-19 vaccine regimens within an 18-month follow-up study.

Early reports on coronavirus disease 2019 (COVID-19) vaccines presented the short-term adverse events (AEs). This follow-up study investigated a standard regimen based on protein subunit vaccines, PastoCovac and PastoCovac Plus, and the combinational vaccine regimens including AstraZeneca/PastoCovac Plus and Sinopharm/PastoCovac Plus. The participants were followed up to 6 months post the booster shot. All the AEs were collected through in-depth interviews using a valid researcher-made questionnaire and were evaluated regarding the association with the vaccines. Of the 509 individuals, 6.2% of the combinational vaccine participants had late AEs, of whom 3.3% suffered from cutaneous manifestations, followed by 1.1% arthralgia complaints, 1.1% with neurologic disorders, 0.3% ocular problems and 0.3% metabolic complications, with no significant difference between the vaccine regimens. For the standard regimen, 2% of the individuals experienced late AEs as (1%), neurological disorders (0.3%), metabolic problems (0.3%) and involvement of joints (0.3%). Notably, 75% of the AEs were persistent up to the end of the study. A low number of late AEs were captured in 18 months as 12 improbable, 5 unclassifiable, 4 possible and 3 probable associated AEs with the vaccine regimens. The benefits of COVID-19 vaccination far exceed the potential risks and late AEs seem to be uncommon.

The impact of the COVID-19 pandemic on depression in community-dwelling older adults: a prospective cohort study.

BACKGROUND: There are growing concerns about the impact of the COVID-19 pandemic on the mental health of older adults. We examined the effect of the pandemic on the risk of depression in older adults. METHODS: We analyzed data from the prospective cohort study of Korean older adults, which has been followed every 2 years. Among the 2308 participants who completed both the third and the fourth follow-up assessments, 58.4% completed their fourth follow-up before the outbreak of COVID-19 and the rest completed it during the pandemic. We conducted face-to-face diagnostic interviews using Mini International Neuropsychiatric Interview and used Geriatric Depression Scale. We performed generalized estimating equations and logistic regression analyses. RESULTS: The COVID-19 pandemic was associated with increased depressive symptoms in older adults [b (standard error) = 0.42 (0.20), p = 0.040] and a doubling of the risk for incident depressive disorder even in euthymic older adults without a history of depression (odds ratio = 2.44, 95% confidence interval 1.18-5.02, p = 0.016). Less social activities, which was associated with the risk of depressive disorder before the pandemic, was not associated with the risk of depressive disorder during the pandemic. However, less family gatherings, which was not associated with the risk of depressive disorder before the pandemic, was associated with the doubled risk of depressive disorder during the pandemic. CONCLUSIONS: The COVID-19 pandemic significantly influences the risk of late-life depression in the community. Older adults with a lack of family gatherings may be particularly vulnerable.

Neurodevelopmental disorders: 2023 update.

Several advances in the field of neurodevelopmental diseases (NDDs) have been reported by 2022. Of course, NDDs comprise a diverse group of disorders, most of which with different aetiologies. However, owing to the development and consolidation of technological approaches, such as proteomics and RNA-sequencing, and to the improvement of brain organoids along with the introduction of artificial intelligence (AI) for biodata analysis, in 2022 new aetiological mechanisms for some NDDs have been proposed. Here, we present hints of some of these findings. For instance, centrioles regulate neuronal migration and could be behind the aetiology of periventricular heterotopia; also, the accumulation of misfolded proteins could explain the neurological effects in COVID-19 patients; and, autism spectrum disorders (ASD) could be the expression of altered cortical arealization. We also cover other interesting aspects as the description of a new NDD characterized by deregulation of genes involved in stress granule (SG) assemblies, or the description of a newly discovered neural progenitor that explains the different phenotypes of tumours and cortical tubers in tuberous sclerosis complex (TSC) disease; and how it is possible to decipher the aetiology of sudden unexplained death in childhood (SUDC) or improve the diagnosis of cortical malformations using formalin-fixed paraffin-embedded samples.

The CH24H metabolite, 24HC, blocks viral entry by disrupting intracellular cholesterol homeostasis.

Cholesterol-24-hydroxylase (CH24H or Cyp46a1) is a reticulum-associated membrane protein that plays an irreplaceable role in cholesterol metabolism in the brain and has been well-studied in several neuro-associated diseases in recent years. In the present study, we found that CH24H expression can be induced by several neuroinvasive viruses, including vesicular stomatitis virus (VSV), rabies virus (RABV), Semliki Forest virus (SFV) and murine hepatitis virus (MHV). The CH24H metabolite, 24-hydroxycholesterol (24HC), also shows competence in inhibiting the replication of multiple viruses, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). 24HC can increase the cholesterol concentration in multivesicular body (MVB)/late endosome (LE) by disrupting the interaction between OSBP and VAPA, resulting in viral particles being trapped in MVB/LE, ultimately compromising VSV and RABV entry into host cells. These findings provide the first evidence that brain cholesterol oxidation products may play a critical role in viral infection.

Characteristics of febrile seizures with SARS-CoV-2 infection in the Omicron era.

Background: While the pandemic of coronavirus disease 2019 (COVID-19) is ongoing, the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been dominant recently. The Omicron variant causes more seizures in pediatric patients compared with previously circulated variants. This study aimed to investigate the incidence and clinical features of febrile seizure (FS) in pediatric patients with COVID-19 during the Omicron era. Methods: The medical records of pediatric patients (≤18 years of age) diagnosed with COVID-19, who presented with FS between February 2020 and June 2022, were reviewed retrospectively to analyze clinical characteristics of FS in seven university-affiliated hospitals of Korea. Results: Of 664 pediatric patients with COVID-19 during the study period, 46 during the pre-Omicron period and 589 during the Omicron period were included in the study analysis; 29 patients during the transition period were excluded. Among the included patients, 81 (12.8%) had concomitant FS, and most (76.5%) experienced simple FS. All FS episodes occurred during the Omicron period and none of them during pre-Omicron period (P=0.016). Sixty-five (80.2%) and 16 (19.8%) patients were categorized as FS (patient age ≤60 months) and late-onset FS (patient age >60 months), respectively. Underlying neurologic disease (P=0.013) and focal onset seizure (P=0.012) were more common in the late-onset FS group than in the FS group; however, overall clinical manifestations and outcomes including seizures consistent with characteristics of complex FS and subsequent epilepsy were similar between the two groups. Conclusions: As the COVID-19 pandemic persists, the incidence of FS has increased with the emergence of the Omicron variant. About one-fifth of the patients experiencing FS due to infection by the Omicron variant of SARS-CoV-2 were aged >60 months; however, clinical characteristics and outcomes were favorable. More information and long-term prognoses in patients with FS due to COVID-19 should be acquired.

On the Lateness of Pandemic Time

This article applies the Black queer vernacular form of "late" to interrogate arrival the of a privileged group into a consciousness of crisis and recasts the actions of Black LGBTQ+ people during the pandemic as part of a longer history of surviving catastrophe. The colloquial usage of late demonstrates Black queer awareness of the interconnection between the definition of time;its variable valuation;and the multiple, sometimes competing temporalities in which Black queers live and die. Racial disparities to the response of policies implemented during the rise of COVID- 19, as well as the ways in which the habits and pace of Black LGBTQ+ life remained relatively unaffected by the pandemic, reveal the ways history and time unevenly impact different populations within the same crisis. Using Black studies theories of time, Black feminist theories of touch, and Black queer theories of gender and sex, this article illuminates the continuity between constructions of state-sanctioned notions of progress, a contemporary development of pandemic time, and the timing of whiteness as ontologically late. Through a reconsid-eration of the habits of Black queer life as always already attending to one urgency or another this article argues for building toward a crisis-oriented futurity with less concern for or and impulse to redress the lateness of other people.

Evaluation of the late presentation and associated factors of people living with HIV in Turkey.

To identify the frequency of late presentation and late presentation with advanced disease, and associated factors in people living with HIV (PLHIV). Data from PLHIV diagnosed between 2008 and 2021 were retrospectively analyzed. Time of diagnosis (categorized based on key events affecting HIV care continuum e.g., national strategies, HIV guidelines, COVID-19 pandemic) and characteristics of late presenters (LP: CD4 ≤350 cells/mm³ or an AIDS defining event) and late presenters with advanced disease (LPAD: CD4 <200 cells/mm³) were describe. Associations between dependent (LP, LPAD) and independent variables were assessed using univariate/multivariate regression tests and presented as odds ratios (95% confidential interval). Of 1585 individuals (93.7% men), 42.5% were LPs and 19.3% were LPADs. Most common route of transmission was sex between men (54.3%). Non-LPs were younger (30 vs. 34 and 36 years; p < 0.001) and included more men who have sex with men (60.3% vs. 46.3% and 39.5%; p < 0.001). Factors associated with being LP and LPAD were age >30 years, heterosexual/unknown route of transmission (vs. sex between men), diagnosis in 2008-2013 or 2020-2021, (vs. 2014-2019). With reference to Turkish subjects, migrants from Africa had higher odds of being LPAD. LP is still an important health issue in HIV care. Heterosexuality, older age (>30 years), migration from Africa, and the COVID-19 pandemic are associated with delays in HIV presentation in Turkey. These factors need to be considered when developing and implementing policies to enable earlier diagnosis and treatment of PLHIV to achieve UNAIDS 95-95-95 targets.

Late miscarriage and stillbirth in asymptomatic and symptomatic hospitalised pregnant women in Belgium during the first and second waves of COVID-19: a prospective nationwide population-based study.

BACKGROUND: Stillbirth has been recognized as a possible complication of a SARS-CoV-2 infection during pregnancy, probably due to destructive placental lesions (SARS-CoV-2 placentitis). The aim of this work is to analyse stillbirth and late miscarriage cases in unvaccinated pregnant women infected with SARS-CoV-2 during the first two waves (wild-type period) in Belgium. METHODS: Stillbirths and late miscarriages in our prospective observational nationwide registry of SARS-CoV-2 infected pregnant women (n = 982) were classified by three authors using a modified WHO-UMC classification system for standardized case causality assessment. RESULTS: Our cohort included 982 hospitalised pregnant women infected with SARS-CoV-2, with 23 fetal demises (10 late miscarriages from 12 to 22 weeks of gestational age and 13 stillbirths). The stillbirth rate was 9.5‰ for singleton pregnancies and 83.3‰ for multiple pregnancies, which seems higher than for the background population (respectively 5.6‰ and 13.8‰). The agreement between assessors about the causal relationship with SARS-Cov-2 infection was fair (global weighted kappa value of 0.66). Among these demises, 17.4% (4/23) were "certainly" attributable to SARS-CoV-2 infection, 13.0% (3/23) "probably" and 30.4% (7/23) "possibly". Better agreement in the rating was noticed when pathological examination of the placenta and identification of the virus were available, underlining the importance of a thorough investigation in case of intra-uterine fetal demise. CONCLUSIONS: SARS-CoV-2 causality assessment of late miscarriage and stillbirth cases in our Belgian nationwide case series has shown that half of the fetal losses could be attributable to SARS-CoV-2. We must consider in future epidemic emergencies to rigorously investigate cases of intra-uterine fetal demise and to store placental tissue and other material for future analyses.

The Impact of the COVID-19 Pandemic on Older Latino Immigrants

This article examines the impact of the COVID-19 pandemic on Latino immigrants age sixty and older from Cuba, Dominican Republic, El Salvador, Mexico, Puerto Rico, and Venezuela. Based on 178 interviews with immigrants in Florida and Massachusetts, this study identifies the financial and health hardships they endured, the kinds of government and nonprofit aid they accessed, the factors keeping many from accessing aid, and the coping strategies they adopted. Respondents faced unemployment, hunger, and loss of income. Unauthorized immigrants and people in mixed-status families were deliberately excluded from federal aid. Many other immigrants who qualified were reluctant or refused it. Immigrants without legal status and those who had more recently arrived were the most severely affected. Individuals and families responded to these challenges by doubling up, going without food and medicine, and working while sick. Greater outreach and more humane public policies could have prevented much of this suffering.

How Do Late Adults Experience Meaning During the COVID-19 Lockdown? The Role of Intrinsic Goals.

Late adults differ in the degree to which their mental health is impacted by the COVID-19 crisis, with interindividual differences in their capacity to mobilize coping resources playing an important role. Therefore, the search for inner sources of resilience is important to understand late adults' adaptation to this crisis. Based on Goal Content Theory, a mini-theory within the broader Self-Determination Theory, this study aimed to examine whether older adults' valuation and attainment of intrinsic goals represent such a source of resilience. Intrinsic goals would form a solid foundation to experience a sense of meaning during this crisis, which, in turn, relates to higher well-being (i.e., life satisfaction and vitality) and lower ill-being (i.e., symptoms of depression, anxiety, and loneliness). During the second month of the lockdown period in Belgium, 693 older adults (Mage = 70.06, SD = 4.48, range: 65-89 years, 62.1% female) filled out online questionnaires concerning the study variables. Structural equation modeling showed that intrinsic goal attainment and goal importance related positively to experiences of meaning in life which, in turn, were related to higher levels of well-being and lower levels of ill-being. No evidence was found for an interaction effect between intrinsic goal attainment and goal importance. Supporting late adults' pursuit and attainment of meaningful intrinsic goals relates to their well-being and may potentially strengthen their resilience in times of crisis.

[A cross-sectional study of enterovirus nucleic acid test with throat swabs for term late neonates during coronavirus disease 2019]. / æ–°åž‹å† çŠ¶ç— æ¯’æ„ŸæŸ“æœŸé—´è¶³æœˆçš„æ™šæœŸæ–°ç”Ÿå„¿å’½æ‹­å­è‚ é“ç— æ¯’æ ¸é ¸æ£€æµ‹æ¨ªæ–­é¢ç ”ç©¶.

OBJECTIVES: To investigate the positive rate of enterovirus (EV) nucleic acid in throat swabs of term late neonates hospitalized during the coronavirus disease 2019 (COVID-19) epidemic and the clinical characteristics of the neonates. METHODS: A single-center cross-sectional study was performed on 611 term late infants who were hospitalized in the neonatal center from October 2020 to September 2021. Throat swabs were collected on admission for coxsackie A16 virus/EV71/EV universal nucleic acid testing. According to the results of EV nucleic acid test, the infants were divided into a positive EV nucleic acid group (8 infants) and a negative EV nucleic acid group (603 infants). Clinical features were compared between the two groups. RESULTS: Among the 611 neonates, 8 tested positive for EV nucleic acid, with a positive rate of 13.1‰, among whom 7 were admitted from May to October. There was a significant difference in the proportion of infants contacting family members with respiratory infection symptoms before disease onset between the positive and negative EV nucleic acid groups (75.0% vs 10.9%, P<0.001). There were no significant differences between the two groups in demographic data, clinical symptoms, and laboratory test results (P>0.05). CONCLUSIONS: There is a certain proportion of term late infants testing positive for EV nucleic acid in throat swabs during the COVID-19 epidemic, but the proportion is low. The clinical manifestations and laboratory test results of these infants are non-specific. Transmission among family members might be an important cause of neonatal EV infection.

Risk of post-acute sequelae of SARS-CoV-2 infection associated with pre-coronavirus disease obstructive sleep apnea diagnoses: an electronic health record-based analysis from the RECOVER initiative.

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) has been associated with more severe acute coronavirus disease-2019 (COVID-19) outcomes. We assessed OSA as a potential risk factor for Post-Acute Sequelae of SARS-CoV-2 (PASC). METHODS: We assessed the impact of preexisting OSA on the risk for probable PASC in adults and children using electronic health record data from multiple research networks. Three research networks within the REsearching COVID to Enhance Recovery initiative (PCORnet Adult, PCORnet Pediatric, and the National COVID Cohort Collaborative [N3C]) employed a harmonized analytic approach to examine the risk of probable PASC in COVID-19-positive patients with and without a diagnosis of OSA prior to pandemic onset. Unadjusted odds ratios (ORs) were calculated as well as ORs adjusted for age group, sex, race/ethnicity, hospitalization status, obesity, and preexisting comorbidities. RESULTS: Across networks, the unadjusted OR for probable PASC associated with a preexisting OSA diagnosis in adults and children ranged from 1.41 to 3.93. Adjusted analyses found an attenuated association that remained significant among adults only. Multiple sensitivity analyses with expanded inclusion criteria and covariates yielded results consistent with the primary analysis. CONCLUSIONS: Adults with preexisting OSA were found to have significantly elevated odds of probable PASC. This finding was consistent across data sources, approaches for identifying COVID-19-positive patients, and definitions of PASC. Patients with OSA may be at elevated risk for PASC after SARS-CoV-2 infection and should be monitored for post-acute sequelae.

Managing Survivorship after Hematopoietic Cell Transplantation.

PURPOSE OF REVIEW: With improvement in survival after hematopoietic cell transplantation (HCT), it has become important to focus on the late complications experienced by the survivors that may lead to late mortality and morbidity to be able to provide patient-centered care across the transplant continuum. The goals of this article are to describe the status of literature on late complications in HCT survivors; offer a brief overview of the status of the screening, prevention, and management of these complications; and identify opportunities for future practice and research. RECENT FINDINGS: This is an exciting time for the field with increasing awareness about survivorship issues. Studies are moving beyond description to examining pathogenesis of these late complications and identifying biomarkers. The eventual goal is to promote changes in our transplant techniques to decrease the incidence of these complications as well as help develop interventions targeting these late effects. There is also an emphasis on improving health care delivery models to provide optimal post-HCT management for medical and psychosocial complications through close coordination between multiple stakeholders and leveraging technology to help address the barriers in delivery of care to fulfill the unmet needs in this area. The increasing population of HCT survivors with their burden of late effects underscores the need for concerted efforts to improve long-term medical and psychosocial outcomes for this group.

Two Cases of 6-Pyruvoyl Tetrahydropterin Synthase Deficiency: Case Report and Literature Review.

6-pyruvoyl tetrahydropterin synthase deficiency (PTPSD) is a rare neurometabolic disease that can be diagnosed in newborn screening (NBS) and is part of the family of tetrahydrobiopterin deficiency disorders (BH4Ds). It is essential to diagnose and treat this disease early to prevent permanent neurological damage secondary to this neurotransmitter disorder. We present the first two cases of PTPSD in Romania that were genetically confirmed and treated late. Improving the diagnosis and monitoring procedures in Romania with correct metabolic management will prevent severe neurological impairment from PTPSD or other BH4Ds.

Simulation based adaptive vaccine delivery strategy

Inoculation is one of the most common intervention methods to mitigate the number of incidents during an outbreak. It is a crucial point to decide which age or target groups in a society are priorly vaccinated. In this study, we considered this challenge and a late vaccine distribution scenario with a new vaccine delivery strategy. A given population is divided into five age groups with different contact and transmission rates. The proposed strategy distributes weekly shots to people in an age group or groups according to results of simulation modelling different vaccination strategies for a week time horizon by considering historical incident rates of the outbreak. The method is tested against the strategy of vaccinating schoolchildren considered in many related publications in the literature. According to results, for 20 scenarios based on different contact and transmission rates and under three coverage levels, our method outperforms the benchmark strategy under 20% and 30% coverage levels for each scenario. Both strategies mostly follow same distributions and come up with same results under 10% coverage level. We can conclude that the proposed method is robust to changes in contact and transmission rates and provides superior results when coverage levels are relatively high. The method can provide effective vaccination strategies by considering disease dynamics for primarily COVID-19 and future pandemics.

SARS-CoV-2-Related Pediatric Encephalopathy with Biphasic Convulsions and Cortical Blindness: A Case Report

Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is an encephalopathy syndrome that develops during the febrile phase of infection and is characterized by biphasic seizures and bright tree appearance (BTA) on imaging. In this study, we examined a 1-year-old child who was diagnosed with AESD caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. He had a fever for 2 days and was diagnosed with coronavirus disease 2019 on the day of consultation based on a positive antigen test for SARS-CoV-2. The seizures had stopped on arrival to hospital;however, symptoms of encephalopathy persisted. Despite being treated for acute encephalopathy with steroid pulse therapy, vitamins, and remdesivir, he had poor expressive language, and electroencephalography showed generalized slow waves. A repeat head magnetic resonance imaging showed BTA in the parietal and occipital lobes, and seizures recurred during hospital stay. He was also found to have cortical blindness. At the 4-month follow-up, the vision gradually improved and the hand movements recovered. SARS-CoV-2 infection can cause febrile convulsions, which can lead to the development of AESD. Furthermore, a subtype of AESD has occipital lobe predominant lesions that can cause visual impairment.
