We assessed the effects of COVID-19 infection on nasal mucociliary activity.

The study was conducted in the pandemic wards of Adiyaman University Training and Research Hospital during April and May 2020. All patients admitted to the COVID-19 pandemic wards during the study period were invited to participate in the study. The study included 40 adults who agreed to participate and underwent a mucociliary clearance test successfully. The primary outcome was mucociliary clearance time and the secondary variables of interest were age, sex, and sino-nasal outcome test-22 scores. The control group included 40 concomitant healthy patients who visited the outpatient ear, nose and throat clinic with non-nasal symptoms.

The study included 40 COVID-19-positive patients and 40 healthy controls. The mean mucociliary clearance times of the study (15.53 ± 5.57min) and control (9.50 ± 3.70min) groups were significantly different (Z = 4.675, p < 0.001). However, the mucociliary clearance time was not significantly different between males and females (t = 0.590, p = 0.558).

Nasal mucociliary clearance time was prolonged in COVID-19 patients compared to healthy controls. Thus, we conclude that smell and taste are crucial symptoms that should not be overlooked in patients suspected of COVID-19 disease.

A retrospective analysis on GNB at the first episode of febrile neutropenia (FN) was conducted among allo-HSCT recipients (age ≥ 20 years) on 500 mg/day of oral LVFX prophylaxis. Epidemiological and microbiological features of GNB were investigated and compared between the inappropriate and appropriate empiric therapy groups. In total, FN occurred in 414 allo-HSCT cases, and bacteremia at the first episode of FN occurred in 169 cases. Overall, 29 GNB cases were documented, and the causative organisms identified were Escherichia coli in 21 cases (including 10 ESBLs), Klebsiella pneumoniae in 2, Pseudomonas aeruginosa in 2, and other in 4. The crude 30-day mortality rate was not significantly different among cases of GNB (6.9%), gram-positive bacteremia (GPB) (7.1%), or non-bacteremia (5.4%; P = 0.78). Cefepime (CFPM) was administered in all cases in the inappropriate empiric therapy group, and all causative organisms were ESBL-producing E. coli (ESBL-EC). All patients in the inappropriate empiric therapy group had a low Pitt bacteremia score (≤ 2). Thirty-day mortality did not differ significantly between the inappropriate and appropriate empiric therapy groups (1/10 vs. 1/15, P = 0.61). In conclusion, GNB was not a significant cause of death. In LVFX breakthrough ESBL-EC bacteremia among allo-HSCT recipients, the administration of CFPM as empiric therapy did not lead to significantly poor prognosis. Empiric CFPM administration might be an acceptable strategy.There have been many publications detailing imaging features of malignant transformation of intraductal papillary mucinous neoplasms (IPMN), management and recommendations for imaging follow-up of diagnosed or presumed IPMN. However, there is no consensus on several practical aspects of imaging IPMN that could serve as a clinical guide for radiologists and enable future data mining for research. These aspects include how to measure IPMN, define reporting terminology, standardize reporting and unify guidelines for surveillance. The Society of Abdominal Radiology (SAR) created multiple Disease-Focused Panels (DFP) comprised multidisciplinary panel members who focus on a particular disease, with the goal to develop ways for radiologists to improve patient care, education, and research. DFP members met to identify the current controversies and limitations of imaging pancreatic IPMN. This paper aims to provide a practical review of the key imaging characteristics of IPMN for trainees and practicing radiologists, to guide uniformity of performance and interpretation of surveillance imaging studies, and to improve communication with clinicians by providing a lexicon and reporting template based on the experience of the SAR-DFP panel members.

This study aims to determine whether outcomes following vertebroplasty with high viscosity cement are superior to low viscosity cement and non-inferior to kyphoplasty in the setting of vertebral compression fractures.

We searched for randomized controlled trials and cohort studies assessing cement leakage rate in adult patients with VCFs who underwent vertebroplasty with high (HVCV) or low viscosity cement (LVCV) augmentation, or kyphoplasty (KP) in PubMed, Embase, Ovid, The Cochrane Library, and Web of Science from inception up to December 2019. Two authors extracted data and appraised risk of bias. We performed pairwise meta-analyses in R to compare differences between three treatments and network meta-analysis using frequentist random-effects models for indirect comparison. We used P-score to rate the overall certainty of evidence. The primary outcome was cement leakage rate.

Five RCTs and eight cohort studies with 840 patients and a total of 1280 vertebral bodies were included in the systematic review and network meta-analysis. Compared to LVCV, the relative risk for cement leakage following HVCV and KP was 0.42 (95% CI 0.28-0.61) and 0.83 (95% CI 0.40-1.68), respectively. Our pooled results suggested that HVCV (P-score = 0.99) was better than KP (P-score = 0.36) in cement leakage rate.

The present network meta-analysis demonstrated that HVCV may be associated with lower risk of cement leakage among patients with VCFs as compared to other augmentation techniques. Future prospective studies will validate the findings of this analysis and further elucidate the risk of symptomatic cement leakage.
