The 2015 American Thyroid Association guidelines and trends in hemithyroidectomy utilization for pediatric thyroid cancer

alexandrossfakianakis shared this article with you from Inoreader The 2015 American Thyroid Association guidelines and trends in hemithyroidectomy utilization for pediatric thyroid cancer via Head & Neck Abstract Background In 2015, the American Thyroid Association (ATA) released its inaugural recommendations for the management of thyroid cancer in children. We aim to evaluate whether there has been a change in hemithyroidectomy utilization for pediatric differentiated thyroid cancer, and the association between those changes and the release of the ATA guidelines. Methods The National Cancer Database was queried and identified 4776 patients ≤18 years old with differentiated thyroid cancer. Causal impact time-series analysis and logistic analysis were utilized to assess factors associated with use of hemithyroidectomy. Results Post-2015 hemithyroidectomy rate was greater than predicted based on preguideline trends (predicted: 8.4%, actual: 12.6%, p = 0.001). In logistic analysis of factors associated with hemithyroidectomy use, we find that Papillary histology, tumor size >1 cm, nodal examination, and positive nodes were associated with lower rate of hemithyroidectomy (OR: 0.23, 0.51, 0.62, and 0.18, respectively). Conclusion There has been a significant increase in hemithyroidectomy utilization for pediatric differentiated thyroid cancer. View on Web

Infectious complications in acute graft‐versus‐host disease after Liver transplantation

alexandrossfakianakis shared this article with you from Inoreader Infectious complications in acute graft‐versus‐host disease after Liver transplantation via Transplant Infectious Disease Abstract Background : Graft-versus-host disease (GVHD) following liver transplantation (LT) is rare but can lead to significant mortality. The leading cause of death following GVHD diagnosis is infectious complications. However, there is a lack of clear descriptions concerning infection and antimicrobial management patterns. Our study aims to provide the focused details of all infectious complications of acute GVHD following LT. Methods : We retrospectively reviewed all adult LT recipients with acute GVHD at Mayo Clinic's Transplant Centers from January 1, 2010, to December 31, 2021. Detailed characteristics of infection in each case were described. Results : Among 4,585 LTs performed during this period, 12 (0.3%) patients developed acute GVHD. The median time from transplantation to GVHD diagnosis was 49.0 days [IQR 31.5-99.0]. Ten (83.3%) patients developed severe infections leading to mortality. The most common cause of infection was nosocomial bacteremia from enteric bacteria such as vancomycin-resistant enterococci and gram-negative bacilli. Other infections included breakthrough invasive fungal infections, cytomegalovirus (CMV) reactivation, and Clostridioides difficile colitis. Antimicrobial prophylaxis strategies in most cases were based on the degree of neutropenia – these include levofloxacin for bacterial prophylaxis, nebulized pentamidine for Pneumocystis jiroveci pneumonia prophylaxis, posaconazole for invasive fungal prophylaxis, and valganciclovir based on CMV status. All GVHD patients with severe infections succumbed to these complications. Conclusions : Our study reiterates that despite prophylaxis, infectious complications in GVHD following LT are common and lead to exceptionally high mortality. Individualized antimicrobial treatment, prophylaxis and monitoring strategies remain a critical component of GVHD management. Further study to optimize these practices is required.

Susceptibility to HIV-1 Acquisition linked to Malaria Exposure: A Case-control Study

alexandrossfakianakis shared this article with you from Inoreader Susceptibility to HIV-1 Acquisition linked to Malaria Exposure: A Case-control Study via Clinical Infectious Diseases Advance Access Abstract HIV and malaria infection rates overlap across sub-Saharan Africa, but factors influencing their co-occurrence are unclear. In a case-control study, we investigated whether malaria exposure increases risk of HIV-1 acquisition. Prior to seroconverting, HIV-positive cases had significantly higher malaria-associated antibodies compared to HIV-negative controls, linking malaria exposure to HIV-1 acquisition. View on Web

Effect of antiviral treatment on hepatitis B virus integration and hepatocyte clonal expansion

alexandrossfakianakis shared this article with you from Inoreader Effect of antiviral treatment on hepatitis B virus integration and hepatocyte clonal expansion via Clinical Infectious Diseases Advance Access Abstract Background This study investigated the effect of nucleos(t)ide analogues (NUC) treatment on HBV DNA integration and hepatocyte clonal expansion, both of which are implicated in hepatocellular carcinoma (HCC) in chronic hepatitis B. Methods Twenty-eight patients receiving NUCs (11 lamivudine, 7 telbivudine, 10 entecavir) were included. All had liver biopsies at baseline and year 1, and seven had a third biopsy at year 10. HBV DNA integration and hepatocyte clone size were assessed by inverse PCR. Results All patients had detectable HBV integration at baseline, with a median integration frequency of 1.01×109 per liver and hepatocyte clone size of 2.41×105. Neither integration frequency nor hepatocyte clone size correlated with age and HBV virologic parameters. After one year of treatment, HBV integration was still detectable in all patients, with a median of 5.74×108 integration per li ver (0.22 log reduction; P = .008) and hepatocyte clone size of 1.22×105 (0.40 log reduction; P = .002). HBV integration remained detectable at year 10 of treatment, with a median integration frequency of 4.84×107 integration per liver (0.93 log reduction from baseline) and hepatocyte clone size of 2.55×104 (1.02 log reduction from baseline). From baseline through year 1 to year 10, there was a decreasing trend in both integration frequency and hepatocyte clone size (P = .066 and.018, respectively). Conclusions NUCs reduced both HBV DNA integration and hepatocyte clonal expansion, suggesting another alternative pathway besides direct viral suppression to reduce HCC risk. Our findings supported the notion for a long-term NUC treatment to prevent HCC. View on Web

Reduced Odds of SARS-CoV-2 Reinfection after Vaccination among New York City Adults, July–November 2021

alexandrossfakianakis shared this article with you from Inoreader Reduced Odds of SARS-CoV-2 Reinfection after Vaccination among New York City Adults, July–November 2021 via Clinical Infectious Diseases Advance Access Abstract Background Belief that vaccination is not needed for individuals with prior infection contributes to COVID-19 vaccine hesitancy. Among individuals infected with SARS-CoV-2 before vaccines became available, we assessed whether vaccinated individuals had reduced odds of reinfection. Methods We conducted a case-control study among adult New York City residents who tested positive for SARS-CoV-2 infection in 2020, did not test positive again >90 days after initial positive test through July 1, 2021, and did not die before July 1, 2021. Case-patients with reinfection during July–November 2021 and control subjects with no reinfection were matched (1:3) on age, sex, timing of initial positive test in 2020, and neighborhood poverty level. Matched odds ratios (mOR) and 95% confidence intervals (CI) were calculated using conditional logistic regression. Results Of 349,827 eligible adults, 2,583 were reinfected during July� �November 2021. Of 2,401 with complete matching criteria data, 1,102 (45.9%) were known to be symptomatic for COVID-19-like-illness, and 96 (4.0%) were hospitalized. Unvaccinated individuals, compared with individuals fully vaccinated within the prior 90 days, had elevated odds of reinfection (mOR, 3.21; 95% CI, 2.70, 3.82), of symptomatic reinfection (mOR, 2.97; 95% CI, 2.31, 3.83), and of reinfection with hospitalization (mOR, 2.09; 95% CI, 0.91, 4.79). All three vaccines authorized or approved for use in the U.S. were similarly effective. Conclusion Vaccination reduced odds of reinfections when the Delta variant predominated. Further studies should assess risk of severe outcomes among reinfected persons as new variants emerge, infection- and vaccine-induced immunity wanes, and booster doses are administered. View on Web
