ABSTRACT

Serum Wisteria floribunda agglutinin-positive Mac-2 binding protein (WFA+-M2BP) is a novel marker for evaluating fibrosis and predicting the development of hepatocellular carcinoma (HCC). However, the role of WFA+-M2BP in the prognosis of HCC patients after curative surgery remains unknown. In this study, we aimed to evaluate the prognostic role of serum WFA+-M2BP in HCC patients after curative resection and liver transplantation. We enrolled 460 HCC patients (357 resection and 103 transplantation) to analyze the risk factors for HCC recurrence and patient's survival. We employed time-to-event models using univariate and multivariable Cox proportional hazards regression analyses and calculated the hazard ratios (HRs) and adjusted HRs with their corresponding 95% confidence intervals (CIs). The levels of WFA+-M2BP were 0.19 -14.51 COI (median 1.08) in patients of hepatectomy and 0.47-19.90 COI (median 6.0) in transplant patients. The levels of WFA+-M2BP in liver transplant patients is much higher than that of hepatectomy patients. Overall, liver fibrotic stage was positively correlated to WFA+-M2BP levels (P<0.0001). This study demonstrated that elevated WFA+-M2BP level (COI ≥0.75) was associated with a higher HCC recurrence rate in the resection group (P<0.001). Survival analysis showed that an elevated WFA+-M2BP level (COI ≥1.43) is associated with a higher mortality risk after surgical resection (P=0.0088) in the univariate analysis only. In liver transplant patients, WFA+-M2BP level (COI ≥3.81) did not predict HCC recurrence at all, but was associated poor survival after transplantation, with a borderline significance (P=0.0943). Serum WFA+-M2BP is a reliable marker for liver fibrosis in the present study. It is also reli able marker to predict prognosis of HCC after surgical resection. However, the prognostic role of WFA+-M2BP in HCC related transplants is equivocal, which is different from that of surgical resection.

Chronic Cough: Evaluation of Patients’ Motivation to Undergo Cough Suppression Therapy

xlomafota13 shared this article with you from Inoreader
Chronic cough is a persistent cough lasting greater than eight weeks. The prevalence rate is estimated to be 9% to 33% in the United States. There are several treatment modalities described in current literature including medical, surgical, and behavioral interventions. Behavioral intervention with a speech-language pathologist (SLP) includes education on laryngeal hygiene and the voluntary control of cough as well as respiratory retraining to suppress or reduce the duration of cough. Cough suppression therapy, like other behavioral therapies, requires patient motivation and commitment to participation and completion in therapy.

Sprache · Stimme · Gehör 2022; 46: 44-50
DOI: 10.1055/a-1745-7502

Hintergrund Ob sich die an unauffälligen Kindern beschriebenen Reifungsprozesse des zentralen Hörsystems auch an Kindern mit auditiven Verarbeitungs- und Wahrnehmungsstörungen (AVWS) im Grundschulalter nachweisen lassen, sollte an 2 Schülerjahrgängen (1. und 4. Klasse) im Kontrollgruppenvergleich untersucht werden. Material und Methoden In die Auswertung gingen 7 Testergebnisse von 82 Erstklässlern (40 mit AVWS; 42 unauffällige Kinder) und 65 Viertklässlern (35 mit AVWS; 30 unauffällige Kinder) ein. Es wurde eine ANOVA mit dem Gesamtsummenwert aus folgenden 7 Untersuchungen sowie anschließend eine MANOVA mit den Einzeltestergebnissen durchgeführt: Göttinger Sprachaudiometrie II im Störgeräusch; dichotisches Wortpaarverstehen (Uttenweiler-Test); Phonemdifferenzierung, Phonemidentifikation, Phonemanalyse (Subtests aus Heidelberger Lautdifferenzierungstest); Zahlenfolgen-Gedächtnis (Subtest aus psycholinguistischem Entwicklungstest); Mottier-Test. Ergebnisse Die ANOVA zeigte signifikante Haupteffekte von „Schuljahr" (p < 0,001; η² = 0,418) und „Gruppe" (p < 0,001; η² = 0,690), jedoch keine Interaktionseffekte zwischen beiden. Das Ergebnis der MANOVA war ähnlich bzgl. der o. g. Haupteffekte; nur für 2 Tests (Phonemidentifikation, Phonemanalyse) wurde die Interaktion der Faktoren Schuljahr und Gruppe mit jeweils geringen Effektstärken von 3 bzw. 6 % statistisch signifikant. Diskussion Gemäß dieser Querschnittsstudie scheint der Unterschied zwischen den beiden Gruppen unabhängig vom Schuljahr zu sein. Fazit Im Grundschulalter gibt es nicht nur für unauffällige Kinder, sondern auch für solche mit AVWS Hinweise auf eine Reifung des zentralen Hörsystems.

Full coverage path planning algorithm for MRgFUS therapy

xlomafota13 shared this article with you from Inoreader

ABSTRACT

Background

High-quality methods for Magnetic Resonance guided Focused Ultrasound (MRgFUS) therapy planning are needed for safe and efficient clinical practices. Herein, an algorithm for full coverage path planning based on preoperative MR images is presented.

Methods

The software functionalities of an MRgFUS robotic system were enhanced by implementing the developed algorithm. The algorithm's performance in accurate path planning following a Zig-Zag pathway was assessed on MR images. The planned sonication paths were performed on acrylic films using the robotic system carrying a 2.75 MHz single element transducer.

Results

Ablation patterns were successfully planned on MR images and produced on acrylic films by overlapping lesions with excellent match between the planned and experimental lesion shapes.

Conclusions

The advanced software was proven efficient in planning and executing full ablation of any segmented target. The reliability of the algorithm could be enhanced through the development of a fully automated segmentation procedure.

Pituitary Gland Surgical Emergencies: The Role of Endoscopic Intervention

xlomafota13 shared this article with you from Inoreader

Otolaryngol Clin North Am. 2022 Mar 4:S0030-6665(21)00252-8. doi: 10.1016/j.otc.2021.12.016. Online ahead of print.

ABSTRACT

True pituitary surgical emergencies are rare. These events can occur throughout the perioperative period and are broadly categorized by the timing of occurrence. Acute indications for emergent pituitary surgery include pituitary apoplexy, vision loss, and severe Cushing presentation. Emergencies may also occur intraoperatively, secondary to bleeding. Postoperative emergencies include epistaxis, pneumocephalus, and intracranial bleeding. Cerebrospinal fluid (CSF) leak occurs in about 37.4% of transsphenoidal sellar surgery, yet postoperative CSF leaks are less frequent at approximately 2.6%. As they occur often during pituitary surgery, CSF leaks alone are generally not considered a true surgical emergency unless associated with symptomatic tension pneumocephalus.

The effects of muscle weakness on speech are currently not fully known. We investigated the relationships between maximum tongue pressure and second formant transition in adults with different types of dysarthria. It focused on the slope in the second formant transition because it reflects the tongue velocity during articulation. Sixty-three Japanese speakers with dysarthria (median age, 68 years; interquartile range, 58–77 years; 44 men and 19 women) admitted to acute and convalescent hospitals were included. Thirty neurologically normal speakers aged 19–85 years (median age, 22 years; interquartile range, 21.0–23.8 years; 14 men and 16 women) were also included. The relationship between the maximum tongue pressure and speech function was evaluated using correlation analysis in the dysarthria group. Speech intelligibility, the oral diadochokinesis rate, and the second formant slope were based on the impaired speech index. More than half of the speakers had mild to moderate dys arthria. Speakers with dysarthria showed significantly lower maximum tongue pressure, speech intelligibility, oral diadochokinesis rate, and second formant slope than neurologically normal speakers. Only the second formant slope was significantly correlated with the maximum tongue pressure (r = 0.368, p = 0.003). The relationship between the second formant slope and maximum tongue pressure showed a similar correlation in the analysis of subgroups divided by sex. The oral diadochokinesis rate, which is related to the speed of articulation, is affected by voice on/off, mandibular opening/closing, and range of motion. In contrast, the second formant slope was less affected by these factors. These results suggest that the maximum isometric tongue strength is associated with tongue movement speed during articulation.
