RESUMO
PURPOSE: Coronavirus disease-2019 (COVID-19) is associated with a wide spectrum of clinical symptoms including acute respiratory failure. Biomarkers that can predict outcomes in patients with COVID-19 can assist with patient management. The aim of this study is to evaluate whether procalcitonin (PCT) can predict clinical outcome and bacterial superinfection in patients infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). METHODS: Adult patients diagnosed with SARS-CoV-2 by nasopharyngeal PCR who were admitted to a tertiary care center in Boston, MA with SARS-CoV-2 infection between March 17 and April 30, 2020 with a baseline PCT value were studied. Patients who were presumed positive for SARS-CoV-2, who lacked PCT levels, or who had a positive urinalysis with negative cultures were excluded. Demographics, clinical and laboratory data were extracted from the electronic medical records. RESULTS: 324 patient charts were reviewed and grouped by clinical and microbiologic outcomes by day 28. Baseline PCT levels were significantly higher for patients who were treated for true bacteremia (p = 0.0005) and bacterial pneumonia (p = 0.00077) compared with the non-bacterial infection group. Baseline PCT positively correlated with the NIAID ordinal scale and survival over time. When compared to other inflammatory biomarkers, PCT showed superiority in predicting bacteremia. CONCLUSIONS: Baseline PCT levels are associated with outcome and bacterial superinfection in patients hospitalized with SARS-CoV-2.

BACKGROUND: The need for extended postoperative antibiotics (Abx) for complicated (gangrenous or perforated) appendicitis (CA) remains unclear. We hypothesize that giving ≤24 h of Abx for CA is not inferior to a longer duration in preventing infectious complications after appendectomy. METHODS: In this post hoc analysis of a prospective multicenter study, only patients with intraoperative diagnosis of CA were included. ANOVA and Chi-squared tests were used to compare length of stay, 30-day readmission rates, surgical site infection (SSI), and intra-abdominal abscess (IAA) between patients receiving ≥96 h and ≤24 h of Abx. RESULTS: Of 751 patients with CA, 704 met inclusion criteria. Mean age was 48 (±17) y; 391 (56%) were male. A total of 185 (26%) received Abx for ≤24 h and 100 (14% of overall) received no Abx. 85 (12%) patients were lost to follow-up at 30 d postop. Twenty-seven (4%) patients developed an SSI (≤24 h = 5 (3%), ≥96 h = 22 (5%), P = 0.502) and 82 (13%) developed IAA (≤24 h = 11 (7%), ≥96 h = 71 (15%), P = 0.008) within 30d postop. Sixty-six (11%) patients underwent a secondary intervention for infection within 30 d postop. 41% of SSIs (11/27) and 60% (49/82) of IAA occurred during the index hospitalization. On the multivariate analysis, there was not any evidence of an association between the duration of Abx and an increased rate of SSI (P = 0.539), IAA (P = 0.274), emergency department visits (P = 0.509), readmission (P = 0.911), or secondary interventions (P = 0.523). CONCLUSIONS: No evidence of an association between the duration of Abx (≤24 h versus ≥ 96 h) for complicated appendicitis and an increased rate of SSI was observed and ≤24 h duration was associated with shorter length of stay. Because of possible selection bias, adequately powered randomized trials are required to definitely prove noninferiority of shorter course Abx duration.

BACKGROUND: Both stenosing tenosynovitis and Dupuytren's contracture are common conditions encountered in hand surgery. Connections between 2 diseases have been suggested in literature. The purpose of this study was to examine whether there's an association between the 2 processes. METHODS: A retrospective chart review was performed to include all patients seen by a single surgeon between 2014 and 2017 with the diagnosis of either trigger finger or Dupuytren's contracture in the same hand. Patients' demographics, medical history, social and surgical histories are recorded. Univariate and multivariate analysis were conducted. RESULTS: A cohort of 238 patients was identified. One hundred ninety-two patients were diagnosed with trigger finger. Eighty-nine patients were diagnosed with Dupuytren's contracture. Forty-three patients carried both diagnoses. Median age was 61.6 (56-72). Half were male (50.4%) and 66.8% reported current alcohol intake. Other factors include history of former or current tobacco use (52.9%), diabetes (23.9%), and manual labor (31.1%). In the univariate model, trigger finger, sex, and age were significantly associated with the diagnosis of Dupuytren's contracture, and Dupuytren's contracture and sex were significantly associated with the trigger finger diagnosis. Diabetes, manual labor, use of alcohol and tobacco were not significant. In the multivariate model, age and trigger finger were significantly associated with Dupuytren's contracture. CONCLUSIONS: Significant association between stenosing tenosynovitis and Dupuytren's contracture was identified in our patient cohort. Patients with stenosing tenosynovitis may be at an increased risk of developing Dupuytren's contracture or vice versa.
RESUMO
BACKGROUND: As more pneumothoraxes (PTX) are being identified on chest computed tomography (CT), the empiric trigger for tube thoracostomy (TT) versus observation remains unclear. We hypothesized that PTX measuring 35 mm or less on chest CT can be safely observed in both penetrating and blunt trauma mechanisms. METHODS: A retrospective review was conducted of all patients diagnosed with PTX by chest CT between January 2011 and December 2016. Patients were excluded if they had an associated hemothorax, an immediate TT (TT placed before the initial chest CT), or if they were on mechanical ventilation. Size of PTX was quantified by measuring the radial distance between the parietal and visceral pleura/mediastinum in a line perpendicular to the chest wall on axial imaging of the largest air pocket. Based on previous work, a cutoff of 35 mm on the initial CT was used to dichotomize the groups. Failure of observation was defined as the need for a delayed TT during the first week. A univariate analysis was performed to identify predictors of failure in both groups, and multivariate analysis was constructed to assess the independent impact of PTX measurement on the failure of observation while controlling for demographics and chest injuries. RESULTS: Of the 1,767 chest trauma patients screened, 832 (47%) had PTX, and of those meeting inclusion criteria, 257 (89.0%) were successfully observed until discharge. Of those successfully observed, 247 (96%) patients had a measurement of 35 mm or less. The positive predictive value for 35 mm as a cutoff was 90.8% to predict successful observation. In the univariant analyses, rib fractures (p = 0.048), Glasgow Coma Scale (p = 0.012), and size of the PTX (≤35 mm or >35 mm) (P < 0.0001) were associated with failed observation. In multivariate analysis, PTX measuring 35 mm or less was an independent predictor of successful observation (odds ratio, 0.142; 95% confidence interval, 0.047-0.428)] for the combined blunt and penetrating trauma patients. CONCLUSION: A 35-mm cutoff is safe as a general guide with only 9% of stable patients failing initial observation regardless of mechanism. LEVEL OF EVIDENCE: Therapeutic, level III.

OBJECTIVE: To assess the awareness and attitudes of the general public in Lebanon regarding the interactions between physicians and pharmaceutical companies. SETTING: Primary healthcare clinics and shopping malls in the Greater Beirut Area. PARTICIPANTS: 263 participants completed the questionnaire, of whom 62% were female and 38% were male. Eligible participants were Arabic-speaking or English-speaking adults (age≥18â years) residing in Lebanon for at least 5â years. PRIMARY AND SECONDARY OUTCOME MEASURES: Awareness, attitudes and beliefs of the general public. RESULTS: 263 out of 295 invited individuals (89% completion rate) completed the questionnaire. While the majority of participants were aware of pharmaceutical company presence (or absence) in physicians' offices (range of 71-76% across questions), smaller percentages were aware of gift-related practices of physicians (range of 26-69% across questions). 40% thought that the acceptance of small gifts or meals by physicians is wrong/unethical. The percentage of participants reporting lower trust in physicians due to their participation in various pharmaceutical company-related activities ranged from 12% to 45% (the highest percentage being for large gifts). Participants who reported receiving free medication samples were significantly more likely to consider physicians' acceptance of small gifts as 'not a problem' than 'unethical' (OR=1.53; p=0.044). CONCLUSIONS: Participants in our survey were generally more aware of pharmaceutical company presence (or absence) in physicians' offices than of gift-related practices of physicians. While the level of trust was not affected for the majority of participants for various types of interactions, it was affected the most for accepting large gifts.
