    Abstract The coronavirus disease 2019 (COVID-19) global pandemic, which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), remains uncontrolled, with the spread of emerging variants. According to accumulating evidence, diabetes is one of the leading risk factors for a severe COVID-19 clinical course, depending on the glycemic state before admission and during COVID-19 hospitalization. Multiple factors are thought to be responsible, including an altered immune response, coexisting comorbidity, and disruption of the renin-angiotensin system through the virus-host interaction. However, the precise underlying mechanisms remain under investigation. Alternatively, the focus is currently on the diabetogenic and ketosis-prone potential of SARS-CoV-2 itself, even for probable triggers of stress and steroid-induced hyperglycemia in COVID-19. In this article, we present a comprehensive review of the recent literature on the clinical and experimental findings associated with diabetes and COVID-19, and we discuss their bidirectional relationship, i.e., the risk for an adverse prognosis and the deleterious effects on glycometabolism. Accurate assessments of the incidence of new-onset diabetes induced by COVID-19 and its pathogenicity are still unknown, especially in the context of the circulation of SARS-CoV-2 variants, such as Omicron (B.1.1.529), which is a major challenge for the future.

    Abstract A 53-year-old man with adult-onset Still's disease developed severe streptococcal toxic shock syndrome (STSS) due to Streptococcus dysgalactiae subsp. equisimilis (SDSE), following retroperitoneal panniculitis. He was receiving tocilizumab (TCZ), an interleukin-6 receptor inhibitor. The modifying effect of TCZ on the immune response and the pathophysiology of SDSE infection may have led to retroperitoneal panniculitis and atypical STSS with delayed shock and flare of soft tissue inflammation.

    Abstract Platypnea-orthodeoxia syndrome (POS) is a rare disorder associated with coronavirus disease 2019 (COVID-19) pneumonia. However, POS may be underdiagnosed. We report the case of a 59-year-old female patient with POS complicated by pulmonary embolism in COVID-19. Imaging revealed ground-glass opacities predominantly in the lower lobes and a pulmonary embolus in the right upper lobe. She was diagnosed with POS due to marked postural discrepancies between supine and upright oxygen saturations and blood oxygenation. Intracardiac shunt, one of the etiologies of POS, was not detected by bubble contrast echocardiography, and postural de-saturation gradually improved with methylprednisolone and edoxaban administration. In our literature review, only 3 of the 16 patients with POS associated with COVID-19 had cardiac shunting, suggesting that moderate to severe COVID-19 causes POS without cardiac shunts. COVID-19-associated vasculopathy and lower lung lesion predominance in COVID-19 pneumonia may cause ventilation-perfusion mismatch due to gravitational shunting of blood into the poorly ventilated lower lungs in the upright position, which may ultimately cause POS. Hypoxemia impedes rehabilitation, whereas early initiation of supine positioning in bed, with knowledge of the pathophysiology of POS, may have a positive effect.

    Abstract Breakthrough candidemia (BrC) is a significant problem in immunocompromised patients, particularly those with hematological disorders. To assess the characteristics of BrC in patients with hematologic disease treated with novel antifungal agents, we collected clinical and microbiological information on said patients from 2009 to 2020 in our institution. Forty cases were identified, of which 29 (72.5%) received hematopoietic stem cell transplant (HSCT)-related therapy. At BrC onset, the most administered class of antifungal agents were echinocandins, administered to 70% of patients. Candida guilliermondii complex was the most frequently isolated species (32.5%), followed by C. parapsilosis (30%). These two isolates were echinocandin-susceptible in vitro but had naturally occurring FKS gene polymorphisms that reduced echinocandin susceptibility. Frequent isolation of these echinocandin-reduced-susceptible strains in BrC may be associated with the widespread use of echinocandins. In this study, the 30-day crude mortality rate in the group receiving HSCT-related therapy was significantly higher than in the group not receiving it (55.2% versus 18.2%, P = .0297). Most patients affected by C. guilliermondii complex BrC (92.3%) received HSCT-related therapy and had a 30-day mortality rate of 53.8%; despite treatment administration, 3 of 13 patients had persistent candidemia. Based on our results, C. guilliermondii complex BrC is a potentially fatal condition in patients receiving HSCT-related therapy with echinocandin administration.

    Abstract Background: Infection control during COVID-19 outbreaks in nursing facilities is a critical public health issue. Antibody responses before and after the fourth (second booster) dose of wild-type severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine in nursing home residents have not been fully characterized.
    Methods: This study included 112 individuals: 54 nursing home residents (mean age: 84.4 years; 35 SARS-CoV-2-naive and 19 previously infected) and 58 healthcare workers (mean age: 47.7 years; 25 SARS-CoV-2-naive and 33 previously infected). Antispike and antinucleocapsid antibody responses to messenger RNA vaccination were evaluated using serum samples collected shortly and 5 months after the third dose, and shortly after the fourth dose.
    Results: The median immunoglobulin G (IgG) level in SARS-CoV-2-naive residents was similar to that in SARS-CoV-2-naive healthcare workers after the fourth dose (24,026.3 vs. 30,328.6 AU/mL, p = .79), whereas after the third dose the IgG level of SARS-CoV-2-naive residents was approximately twofold lower than that in SARS-CoV-2-naive healthcare workers. In residents with previous SARS-CoV-2 infection, timing of infection in relation to vaccination affected the kinetics of antibody responses. Residents infected after the third dose showed the highest IgG levels after the fourth dose among all groups (median: 64,328.8 AU/mL), in contrast to residents infected before initiating vaccination with antibody levels similar to those of SARS-CoV-2-naive residents.
    Conclusions: Advanced aged nursing home residents, poor responders in the initial SARS-CoV-2 vaccine series, could achieve sufficient antibody responses after the fourth (second booster) vaccination, comparable to those of younger adults.

    Abstract Background: Infection control during COVID-19 outbreaks in nursing facilities is a critical public health issue. Antibody responses before and after the third (booster) dose of SARS-CoV-2 vaccination in nursing home residents have not been fully characterized.
    Methods: This study included 117 individuals: 54 nursing home residents (mean age, 83.8 years; 39 SARS-CoV-2-naive and 15 previously infected) and 63 healthcare workers (mean age, 45.8 years; 32 SARS-CoV-2-naive and 31 previously infected). Anti-spike (receptor-binding domain [RBD]) and anti-nucleocapsid antibody responses to BNT162b2 mRNA vaccination and their related factors were evaluated using pre- (shortly and 6 months after the second dose) and post-booster vaccination samples.
    Results: The median anti-spike (RBD) IgG level in SARS-CoV-2-naive residents 6 months after the second dose was the lowest among the four groups, with a decreasing rate of over 90%. The median rate of increase before and after the third dose in SARS-CoV-2-naive residents was significantly higher than that in SARS-CoV-2-naive healthcare workers (64.1- vs. 37.0-fold, P = 0.003), with the highest level among the groups. The IgG ratio of SARS-CoV-2-naive residents to healthcare workers after the second and third doses changed from one-fifth (20%) to one-half (50%). The rate of increase after the third dose in previously infected individuals was three- to fourfold, regardless of residents or healthcare workers.
    Conclusions: Advanced aged nursing home residents, poor responders in the initial SARS-CoV-2 vaccine series, could obtain sufficient antibody responses with the additional booster dose, despite more than 6 months after the second.

    Abstract Neutralizing potency of humoral immune responses induced by prior infection or vaccination is vital for protecting of individuals and population against severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2). However, the emergence of viral variants that can evade neutralization by vaccine- or infection-induced immunity is a significant public health threat and requires continuous monitoring. Here, we have developed a novel scalable chemiluminescence-based assay for assessing SARS-CoV-2-induced cytopathic effect to quantify the neutralizing activity of antisera. The assay leverages the correlation between host cell viability and ATP levels in culture to measure the cytopathic effect on target cells induced by clinically isolated, replication-competent, authentic SARS-CoV-2. With this assay, we demonstrate that the recently arisen Omicron subvariants BQ.1.1 and XBB.1 display a significant decrease in sensitivity to neutralization by antibodies elicited from breakthrough infections with Omicron BA.5 and from receipt of three doses of mRNA vaccines. Thus, this scalable neutralizing assay provides a useful platform to assess the potency of acquired humoral immunity against newly emerging SARS-CoV-2 variants.

    Abstract Rapidly growing mycobacteria rarely causes parotitis. We report a rare case of Mycobacteroides abscessus subspecies abscessus (MAB) parotitis in a previously healthy 26-year-old woman. She presented to the previous hospital with a swelling over the right parotid region, and a computed tomography scan revealed multiple abscesses in the swollen parotid gland. Histopathology showed granulomatous inflammation with acid-fast bacilli; however, a subsequent culture failed to isolate mycobacterium. Despite repeated antibiotic therapy and multiple surgical interventions including partial incision and drainage of the abscesses, the parotitis did not resolved. At six months after presentation, she was referred to our institute. We performed enlarged resection of the necrotic tissue and abscesses, and the sample cultivated after homogenization was positive for mycobacterium. The isolate was finally identified as MAB. She underwent long-term postoperative antibiotic therapy for MAB, with a favorable outcome. To the best of our knowledge, this is the first case of MAB parotitis where the subspecies has been identified. MAB is much more intractable than the other subspecies. We highlight the importance of the correct identification of MAB, which leads to the appropriate treatment.
