Four complications (20 %) occured postoperatively. Two patients developed partial necrosis at the tip of the flap, and two patients developed superficial epidermolysis. No correlations were found between complications and flap size and the arc of rotation.

The propeller flap is a reliable option for reconstruction of small to moderate defects in the lower extremity with good clinical results and minimal donor-site morbidity. It is applicable for orthopedic surgeons who do not have microsurgical experience or an available microscope in the operating room.

Large gaps remain in our understanding of the role of social media platforms in the dissemination of medical information. This cross-sectional study quantitatively assessed the accuracy and quality of information on YouTube regarding epidural labor analgesia.

YouTube was searched on May 23, 2020 using keywords 'epidural,' 'epidural for labor,' 'epidural for pregnancy,' 'epidural experience,' and 'epidural risks,' and the top 50 viewed videos from each search were screened. Primary outcomes included the proportion of videos containing non-factual information, and video quality analyzed using the modified DISCERN (mDISCERN) score.

Thirteen of 60 (21.7%) videos included non-factual information about epidural analgesia; these videos were viewed more than 16.5 million times (60% of total viewership of the videos analyzed). Mean (standard deviation) mDISCERN score for all included videos was 1.9 (1.3), which is below the threshold for high video-quality. Videos from medical sources (hospitals, medical practices, physicians, other medical professionals) had a higher mDISCERN score compared with videos by non-medical sources (P <0.001). Educational videos from professional societies of obstetrics or obstetric anesthesiology were not captured.

YouTube is an accessible platform for medical information on epidural labor analgesia, although a significant proportion of videos studied contained non-factual information and presented low video quality. Increased efforts by reputable sources including hospitals, physicians, other medical professionals, and professional societies, to disseminate accurate information, are warranted.

Here, we analyzed cerebrospinal fluid (CSF) concentrations of tryptophan, kynurenine, KYNA, QUIN, and PIC utilizing ultra-performance liquid chromatography - tandem mass spectrometry system (UPLC-MS/MS) in persons with bipolar disorder (n = 101) and healthy controls (n = 80) to investigate if the metabolites correlated with depressive symptoms or to the history of suicidal behavior. Furthermore, we analyzed if genetic variants of the enzyme amino-β-carboxymuconate-semialdehyde-decarboxylase (ACMSD) were associated with the CSF concentrations of PIC and QUIN. We found that CSF KYNA and PIC concentrations, as well as the kynurenine/tryptophan ratio were increased in bipolar disorder compared with controls. CSF PIC concentrations were lower in subjects with a history of suicidal behavior than those without, supporting the hypothesis that low CSF PIC is a marker of vulnerability for suicidality. Bipolar subjects taking antidepressants had higher CSF concentrations of kynurenine and KYNA than subjects not given these medications. A negative association was found between a genetic variant of ACMSD and the ratio of PIC/QUIN, indicating that a polymorphism in ACMSD is associated with excess of QUIN formation at the expense of PIC. The present results confirm that the kynurenine pathway is activated in bipolar disorder, and suggest that shifting the activity of the kynurenine pathway away from QUIN production towards a production of KYNA and PIC might be a beneficial therapeutic strategy.
To describe the gross and microscopic anatomy of the sciatic nerve paraneural sheath and to report an ultrasound (US)-guided subparaneural approach to the sciatic nerve in dogs, comparing two different volumes of injectate.

Prospective, randomized, anatomical study.

A group of nine middle-sized adult Mongrel canine cadavers (18 limbs).

The sciatic nerves of three pelvic limbs of two canine cadavers were identified, exposed and isolated between the greater trochanter and the popliteal fossa for gross anatomical and microscopic examination. An additional three pelvic limbs were surgically dissected on the lateral surface of the limb; the sciatic nerves were isolated, and a 26 gauge over-the-needle catheter was inserted through the paraneural sheath under direct visualization. A methylene blue solution was then slowly injected into the subparaneural compartment through the catheter under US visualization using an 8-13 MHz linear-array transducer. Subsequently, 12 pelvic limbs (six cadavers) were randomlysatisfactory nerve staining without evidence of sciatic nerve intraneural injection.
Direct-acting antiviral agents achieve sustained virological response in most chronic hepatitis C patients. However, histological responses are not consistent among all patients. We conducted an observational study to analyze the histological changes after direct-acting antiviral agent therapy.

We recruited 220 patients who achieved sustained virological response after direct-acting antiviral agent. Histology was assessed by liver biopsy and laboratory indices including fibrosis-4 and aspartate aminotransferase to platelet ratio index. Primary outcomes were change in the dynamic laboratory results. Secondary outcomes were histological changes on liver biopsy. We analyzed the factors predictive of histological regression.

The mean fibrosis-4 index decreased from 4.78at baseline to 3.30, 3.31, 3.65, and 3.66atweek 4, 8, end of treatment, and 12 weeks after treatment, respectively (all p<0.01). Mean aspartate aminotransferase to platelet ratio index decreased from 1.62at baseline to 0.61, 0.66, 0.64, and 0.82atweek 4, 8, end of treatment, and 12 weeks after treatment, respectively (all p<0.01). Mean Histological Activity Index at baseline and post-treatment was 6.9±1.9 and 5.0±2.3. The METAVIR fibrosis scores improved in 61.9% of the patients. We compared patients who achieved fibrosis-regression with the non-regression group. There was no significant difference in the baseline host/virological factors between the groups.

Reversal of liver inflammation and fibrosis was achieved in a significant number of patients who received direct-acting antiviral agent. No baseline host or virological factor was predictive of histological regression after antiviral treatment.

Predictors of long-term outcomes of peginterferon (PegIFN) therapy for patients with chronic hepatitis B (CHB) remain to be explored. This study aimed to evaluate the predictive value of virological and immunological biomarkers and outcomes of PegIFN for CHB.

57 HBeAg-negative CHB patients receiving 48 weeks of PegIFN therapy were prospectively followed for a median period of 5.3 years after the end of treatment (EOT). Serum CXCL9 and IP-10 levels were measured. Flow cytometry analysis for T cell subsets was performed in 23 patients. Factors associated with long-term outcomes were analyzed.

The cumulative incidences of virological relapse, clinical relapse and HBsAg loss at year 7 were 18.1%, 0%, 31.6%, respectively, in patients with sustained off-treatment virological response (SVR), and 100%, 67.4%, 6.7%, respectively, in patients without SVR. By multivariate analysis, baseline CXCL9 > 80pg/mL (hazard ratio (HR)=0.418, p=0.018) and on-treatment HBsAg declines were associated with a lower risk of virological relapse. Non-SVR was the only predictor of clinical relapse. Laduviglusib CXCL9 >200pg/mL (HR=8.154, p=0.038) and HBsAg <750 IU/mL (HR=10.507, p=0.036) were baseline predictors of HBsAg loss, while HBsAg decline >1 log at EOT (HR=23.296, p=0.005) was the on-treatment predictor of HBsAg loss. In subgroup patients with available PBMC, populations of T cell subsets correlated with virological and clinical relapses in univariate analysis.

Baseline serum CXCL9 and HBsAg levels could predict HBsAg loss after PegIFN therapy for HBeAg-negative CHB. Combining virological and immunological biomarkers could predict long-term outcomes of PegIFN therapy for HBeAg-negative CHB.

Although considerable attention has been paid to understanding particulate matter (PM) deposition on GI, there has been little focus on identifying which leaf traits might maximise airborne PM removal. This paper examines existing literature to synthesize the state of knowledge on leaf traits most relevant to PM removal. We systematically reviewed measurement studies that evaluated particulate matter accumulated on leaves on street trees, shrubs green roofs, and green walls, for a variety of leaf traits. Our final selection included 62 papers, most from field studies and a handful from wind tunnel studies. The following were variously promoted as useful traits coniferous needle leaves; small, rough and textured broadleaves; lanceolate and ovate shapes; waxy coatings, and high-density trichomes. Consideration of these leaf traits, many of which are also associated with drought tolerance, may help to maximise PM capture. Although effective leaf traits were identified, there is no strong or consistent evidence to identify which is the most influential leaf trait in capturing PM. The diversity in sampling methods, wide comparison groups and lack of background PM concentration measures in many studies limited our ability to synthesize results. We found that several ancillary factors contribute to variations in the accumulation of PM on leaves, thus cannot recommend that selection of urban planting species be based primarily on leaf traits. Further research into the vegetation structural features and standardization of the method to measure PM on leaves is needed.
