RESUMO
Recent literature suggests that approximately 5%-18% of patients diagnosed with severe acute respiratory syndrome coronavirus 2 may progress rapidly to a severe form of the illness and subsequent death. We examined the relationship between sociodemographic, clinical, and laboratory findings with mortality among patients. In this study, 112 patients were evaluated from February to May 2020 and 80 patients met the inclusion criteria. Tocilizumab was administered, followed by methylprednisolone to patients with pneumonia severity index score ≤130 and computerized tomography scan changes. Demographic data and clinical outcomes were collected. Laboratory biomarkers were monitored during hospitalization. Statistical analyses were performed with significance p ≤ .05. A total of 80 patients: 45 males (56.25%) and 35 females (43.75%) met the study inclusion criteria. A total of 7 patients (8.75%) were deceased. An increase in mortality outcome was statistically significantly associated with higher average levels of interleukin-6 (IL-6) with p value (.050), and d-dimer with p value (.024). Bivariate logistics regression demonstrated a significant increased odds for mortality for patients with bacterial lung infections (odds ratio [OR]: 10.83; 95% confidence interval [CI]: 2.05-57.40; p = .005) and multiorgan damage (OR: 103.50; 95% CI: 9.92-1079.55; p = .001). Multivariate logistics regression showed a statistically significant association for multiorgan damage (adjusted odds ratio [AOR]: 94.17; 95% CI: 7.39-1200.78; p = .001). We identified three main predictors for high mortality. These include IL-6, d-dimer, and multiorgan damage. The latter was the highest potential risk for in-hospital deaths. This warrants aggressive health measures for early recognition of the problem and initiation of treatment to reverse injuries.

Respiratory failure in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection appears related to cytokine release syndrome that often results in mechanical ventilation (MV). We investigated the role of tocilizumab (TCZ) on interleukin-6 (IL-6) trends and MV in patients with SARS-CoV-2. In this longitudinal observational study, 112 patients were evaluated from 1 February to 31 May 2020. TCZ was administered followed by methylprednisolone to patients with >3L oxygen requirement and pneumonia severity index score ≤130 with computed tomography scan changes. IL-6, C-reactive protein (CRP), ferritin, lactate dehydrogenase (LDH), D-dimer, and procalcitonin were monitored on days 0, 3, and 6 of therapy. Statistical analyses were performed with significance ≤0.05. Eighty out of 112 SARS-CoV-2-positive patients (45 males, 56.96%; 34 females, 43.04%) were included in this study. Seven patients expired (8.75%) and nine patients required MV (11.25%). Median IL-6 levels pre-administration of TCZ was 342.50 (78.25-666.25) pg/mL compared with post-administration on day 3 (563; 162-783) pg/mL (P < .00001). On day 6, the median dropped to 545 (333.50-678.50) pg/mL compared with day 3 (P = .709). CRP, ferritin, LDH, and D-dimer levels were reduced after TCZ therapy. Early use of TCZ may reduce the need for MV and decrease CRP, ferritin, LDH, and D-dimer levels. The sequential use of methylprednisolone for 72 hours seems to potentiate the effect and prolong the suppression of the cytokine storm. IL-6 levels may be helpful as a prognostic tool.

Anterior cruciate ligament (ACL) reconstruction using the quadriceps tendon (QT) autograft is an increasingly utilized technique that confers less donor site morbidity and comparable outcomes to other historically used graft options. The graft harvest and implantation process present vast variability-particularly regarding the achievement of adequate graft site visualization, consistently attaining a uniform and appropriately sized graft, and subsequent reconstruction of the ACL with the all-soft tissue graft. The purpose of this Technical Note and video is to describe and demonstrate minimally invasive quadriceps tendon autograft harvesting using the Quadriceps Tendon Harvest Guide System (QUADTRAC), and its subsequent implantation within a single-bundle ACL reconstruction with suspensory fixation.
RESUMO
BACKGROUND: Rapid administration of appropriately indicated antibiotics is crucial in septic patients. Sepsis data supports that there is a higher risk of mortality for each hour delay from triage to antibiotic therapy, as well as for inappropriate antibiotic selection. There are a variety of rapid microbial detection systems, such as VERIGENE®, used in acute care facilities to rapidly detect bacteremia and identify resistance markers. Our study investigates the usefulness of VERIGENE® assays in accurately detecting Gram-positive and Gram-negative pathogens when compared to traditional blood culture analysis systems, such as VITEK®. METHODS: 819 Gram-positive and 373 Gram-negative blood samples were collected and tested using both VERIGENE® and VITEK®. Statistical tests were two-tailed and observations were defined as statistically significant if P ≤ 0.05. RESULTS: VERIGENE® detected a pathogen in 816/819 (99.6%) samples of the Gram-positive blood cultures and 367/373 (98.3%) samples of the Gram-negatives compared to 805/819 (98.3%) and 367/373 (98.4%), respectively, using VITEK®. Gram-positive cultures had a sensitivity of 99.5% and a specificity of 27.3% (PPV 99.0%, NPV 42.9%, 98.7% accuracy) with VERIGENE analysis. Gramnegatives had a sensitivity of 99.2% and a specificity of 20.0% (PPV 98.9%, NPV 25.0%, 98.4% accuracy). CONCLUSION: Although statistically insignificant (P = 0.25), VERIGENE® was 1.3% more likely to identify Gram-positive bacteria when compared to conventional methods. Overall, we concluded that VERIGENE® assays are valuable in their ability to rapidly detect microorganisms and resistance markers, given their high sensitivities. This allows for select targeted therapy in patients with sepsis and can ultimately reduce mortality rates.

BACKGROUND: We report a case of spinal abscess/osteomyelitis at the T9-T10 levels in a non-immunocompromised patient who presented with lower extremity weakness secondary to a Mycobacterium abscessus infection. This patient was successfully treated with surgical debridement with amikacin-tigecycline-imipenem triple therapy before and after her debridement. Outcomes and treatment with this rare cause of epidural abscess/osteomyelitis are not well defined at this time. CASE REPORT: Clinical Presentations with this species of mycobacterium are usually systemic with patients presenting with pulmonary and soft tissue infections. The primary presentation of spinal epidural abscess/osteomyelitis is unusual, especially when there is no primary focus such as a lung infection or concurrent bacteremia. CONCLUSION: This paper presents a new case of spinal osteomyelitis without a primary source in addition to 10 previously reported M. abscessus cases. The treatment plans and outcomes suggest that surgical debridement along with a macrolide-based combination therapy should be considered a definitive treatment against Mycobacterium abscesses.
