05). At baseline, also the mean FA (P=0.004) and FA skeleton (P=0.002) were reduced in CP compared to controls. FA of the extracted significant cluster was associated with the daily tobacco use (P=0.001) and duration of CP (P=0.010). At follow-up, the whole-brain FA skeleton was reduced by 1.7% for both CP individuals and controls (P=0.878).

Individuals with CP had widespread cerebral white matter alterations at baseline that can likely be explained by the CP disease and exposure to toxic substances. Otherwise, further progression resembles that in healthy controls.

The objective of this study was to determine whether vocal tract semi-occlusion (SOVT) influenced stress effects on pharyngeal air pressure and upper esophageal sphincter (UES) pressure during phonation. Relationships between dysphonia and stress are well recognized but poorly understood. Stress effects act globally on the body, and may be observed beyond intrinsic laryngeal muscles to include pharyngeal muscles and the UES, which contribute to voice modulation. Phonation with SOVT may provide resistance to stress effects on the vocal tract. We hypothesized that stress effects on pharyngeal air pressure and UES pressure would be measurable with a high-resolution, 360° pressure catheter, and that stress effects would be impacted differently by occlusal and non-occlusal phonatory tasks.

Ten healthy adults performed sustained vowel tasks (comfortable /a/, and loud /a/), and SOVT tasks (bilabial fricative and straw phonation). Each task was performed during a baseline condition, and during stress induced throomponents of the vocal tract during phonation.

These findings help identify possible mechanisms underlying the relationship between stress and voice, and point to the utility of SOVT tasks for training vocal tract resistance to stress. This methodology provides a foundation for measuring changes to extra-laryngeal components of the vocal tract during phonation.

Voice assessment and treatment involve the manipulation of all the subsystems of voice production, and may lead to production of respirable aerosol particles that pose a greater risk of potential viral transmission via inhalation of respirable pathogens (eg, SARS-CoV-2) than quiet breathing or conversational speech.

To characterise the production of respirable aerosol particles during a selection of voice assessment therapy tasks.

We recruited 23 healthy adult participants (12 males, 11 females), 11 of whom were speech-language pathologists specialising in voice disorders. We used an aerodynamic and an optical particle sizer to measure the number concentration and particle size distributions of respirable aerosols generated during a variety of voice assessment and therapy tasks. The measurements were carried out in a laminar flow operating theatre, with a near-zero background aerosol concentration, allowing us to quantify the number concentration and size distributions of respirable aerosol particles pring).Accurate detection of liver steatosis is important for liver disease management. Ultrasound attenuation coefficient estimation (ACE) has great potential in quantifying liver fat content. The ACE methods commonly assume uniform tissue characteristics. However, in vivo tissues typically contain non-uniform structures, which may bias the attenuation estimation and lead to large standard deviations. Here we propose a series of non-uniform structure detection and removal (NSDR) methods to reduce the impact from non-uniform structures during ACE analysis. The effectiveness of NSDR was validated through phantom and in vivo studies. In a pilot clinical study, ACE with NSDR provided more robust in vivo performance as compared with ACE without NSDR, indicating its potential for in vivo applications.

To mitigate a national shortage of WIBP-CorV COVID-19 vaccine, China's regulator approved administering BBIBP-CorV after WIBP-CorV for completion of a primary series. In a pragmatic observational study, we compared immunogenicity and safety of a primary series of WIBP-CorV followed by BBIBP-CorV with a primary series of two doses of BBIBP-CorV.

We invited healthy 18-59-years-old adults who had already received either WIBP-CorV or BBIBP-CorV as their first dose in a primary series to participate in this observational cohort study. Subjects who had received WIBP-CorV as their first dose became the observation group; subjects who had received BBIBP-CorV as their first dose became the control group. All participants received BBIBP-CorV as their second dose. We obtained sera 1, 2, and 6months after second doses for nAb titer measurement by micro-neutralization cytopathic effect assay with SARS-CoV-2 strain HB01, standardized with WHO International Standard for anti-SARS-CoV-2 immunoglobulin. https://www.selleckchem.com/products/pf-06463922.html Safety was assessety of WIBP-CorV followed by BBIBP-CorV was not different than immunogenicity following two doses of BBIBP-CorV for two months after vaccination; safety profiles were acceptable for both regimens. BBIBP-CorV can be used to complete a primary series that started with WIBP-CorV.The coronavirus disease 2019 (COVID-19) pandemic has been a serious healthcare problem worldwide since December 2019. The third dose of heterologous vaccine was recently approved by World Health Organization. The present study compared the reactogenicity and immunogenicity of the reduced and standard third booster dose of the BNT162b2 and mRNA-1273 vaccine in adults who previously received the two-dose CoronaVac vaccine. Results showed that headache, joint pain, and diarrhea were more frequent in the 15 μg- than the 30 μg-BNT162b2 groups, whereas joint pain and chilling were more frequent in the 100 μg- than the 50 μg-mRNA-1273 groups. No significant differences in immunogenicity were detected. These findings demonstrate that the reduced dose of the mRNA vaccines elicited antibody responses against the SARS-CoV-2 delta and omicron variants that were comparable to the standard dose. The reduced dose could be used to increase vaccine coverage in situations of limited global vaccine supply.

This study was designed to detect the prevalence of antibiotic and antiseptic resistance genes, mecA and qacA/B in coagulase negative Staphylococcus (CoNS) species isolated from intensive care unit patients with catheter related blood stream infections (CRBSI) or colonized central venous catheters (CVC).

Consecutive CoNS isolates from ICU patients with CRBSI or colonized central venous catheters were speciated and antibiotic susceptibilities were determined. The mecA and qacA/B genes were detected by polymerase chain reaction.

Eighty-two CoNS isolates from ICU patients with CRBSI (n​=​8) or colonized CVC (n​=​74) were included. The mecA gene was detected in 62 CoNS isolates (76%). The commonest species isolated was S.haemolyticus (n​=​34; 41%) and 30 of these possessed mecA which was significantly higher compared to other CoNS species (p​=​0.036). The qacA/B gene was detected in 13 (16%) isolates. Eleven (13%) CoNS had both genes. A significant association was seen with the presence of mecA and resistance to cloxacillin (p​<​0.001) and erythromycin (p​=​0.046). Presence of qacA/B (p​=​0.007) or both mecA and qacA/B (p​=​0.014) was associated with a higher resistance to clindamycin.

A considerably high prevalence of mecA and qacA/B genes as well as co-existence of both genes is noted among the CoNS isolated from ICU patients. This indicates the need of taking prompt actions in hospital acquired infection prevention including continuous surveillance.

The majority of patients are diagnosed at a localized stage. For these patients, the standard of care is based on an hysterectomy with salpingo oophorectomy±lymph node staging. Through the assessment of histopathologic features, risk groups are determined low, intermediate, high-intermediate, and high risk. Adjuvant strategies are guided by these risk groups. While the prognosis of low-risk and high-risk is well known, that of intermediate and high-intermediate risk is more heterogeneous, and the therapeutic index of adjuvant treatments is more questionable. Several trials (PORTEC [Post Operative Radiation Therapy in Endometrial Carcinoma] I, GOG [Gynecologic Oncology Group] 99, ASTEC [A Study in the Treatment of Endometrial Cancer] EN.5, PORTEC II, Sorbe et al trial) have assessed observation, vaginal cuff brachytherapy and/or pelvic external beam radiotherapy in this population. Vaginal cuff brachytherapy reduces the local recurrencn represent growing concerns. Thus, the use of molecular-integrated risk profile to determine the best adjuvant treatment represent a major way to personalize adjuvant treatment of endometrial cancers, with therapeutic de-escalation opportunity for around half of the high-intermediate risks. However, in the absence of prospective data, inclusion in clinical trials assessing molecular profile-based treatment remains the best therapeutic opportunity.With the establishment of total mesorectal excision for the treatment of rectal cancer, local recurrence rates have significantly decreased. The addition of preoperative external beam irradiation further reduces this risk to less than 6%. As the local treatment becomes successful and more widely used, the associated treatment-related toxicity is becoming clinically important. If 4 to 6% of the patients are to benefit from neo-adjuvant therapy before total mesorectal excision, the acute and the long-term toxicity burden must be reasonable. With the introduction of better-quality imaging for tumour visualization and treatment planning, a new-targeted radiation treatment was introduced with high dose rate endorectal brachytherapy. The treatment concept was tested in phase I and II studies first in the preoperative setting, then as a boost after external beam radiation therapy as a dose escalation study to achieve higher tumour local control in a radical treatment setting with no surgery. High dose rate endorectal brachytherapy is safe and effective in achieving high tumour regression rate and was well tolerated. It is presently explored in a phase III dose escalation study in the non-operative management of patients with operable rectal cancer.The purpose of this article is to give a summary of the progress of magnetic resonance imaging (MRI) in radiotherapy. MRI is an important imaging modality for treatment planning in radiotherapy. However, the registration step with the simulation scanner can be a source of errors, motivating the implementation of all-MRI simulation methods and new accelerators coupled with on-board MRI. First, practical MRI imaging for radiotherapy is detailed, but also the importance of a coherent imaging workflow incorporating all imaging modalities. Second, future evolutions and research domains such as quantitative imaging biomarkers, MRI-only pseudo computed tomography and radiomics are discussed. Finally, the application of MRI during radiotherapy treatment is reviewed the use of MR-linear accelerators. MRI is increasingly integrated into radiotherapy. Advances in diagnostic imaging can thus benefit radiotherapy, but specific radiotherapy constraints lead to additional challenges and require close collaboration between radiologists, radiation oncologists, technologists and physicists.
