Airway smooth muscle remodeling and hyperresponsiveness are critical determinants of asthma severity, but the precise mechanisms regulating these disease processes remain elusive. In their latest study published in PNAS, Trebak and colleagues demonstrate that STIM1 (stromal-interacting molecule 1) expression is upregulated in airway smooth muscle cells during asthma and facilitates Ca2+ influx to drive airway remodeling and hyperresponsiveness.
The aim of the present study was to assess factors associated with a repeat operative vaginal delivery (OVD) in women with a previous history of OVD.

A single-centre retrospective observational study was performed in the maternity ward of the Angers University Hospital between 20/09/2010 and 01/04/2021. All the patients who underwent an OVD between 01/09/2010 and 31/10/2013 (delivery n°1, n=1215) and who subsequently delivered up to the 01/04/2021 (delivery n°2, n=652) were included. Multivariate logistic regression was used to assess the risk of subsequent recurrent OVD, adjusted for clinical potential confounder based on univariate analysis.

Among the 520/652 (79.7%) patients who delivered vaginally during delivery n°2, 51/520 (9.8%) had undergone a repeated OVD. Gestational age, parity, history of uterine scars, percentage of labour's induction and the duration of labor were similar between patients who delivered spontaneously and those who required an OVD during delivery n°2. There were 7/51 (13.7%) to 20/469(4.3%) in cases of spontaneous vaginal delivery n°2 (p less then 0.01). A posterior cephalic presentation increased the risk of subsequent OVD by 3.7 [Confidence Interval 95% (1.4-9.6), p less then 0.01] CONCLUSION In the case of a history of OVD, a low proportion of women required a repeated OVD (9.8%). The only factor associated with the need for repeated OVD was a persistent fetal cephalic posterior presentation at the time of delivery.Accidental iatrogenic displacement of third molars in peripheral soft tissues is a major intraoperative complication, but is considered rare. A young women reported discomfort during mandibular lateral movements since she underwent the extraction her impacted third molars under general anesthesia, 2 years before. The clinical examination was not specific except for a laterality limitation of the right mandibular movements. The germ of 28 appeared radiologically encapsulated in the peripheral muscle tissues in the left parapharyngeal space and showed no signs of ankylosis. After measurement of the benefit-risk balance the surgical extraction of the foreign body has been successfully carried out. selleck kinase inhibitor After 6 weeks the patient was able to regain bilateral symmetrical mandibular laterality movements. It appeared that tooth 28 was interfering with the movements of the manducatory function, either by obstructing the mandibular path, and/or by irritating the pterygoid muscles or other peripheral tissues .
Optic pathway gliomas (OPGs) typically occur in the first decade of life and 40%-50% are not associated with neurofibromatosis 1 (NF1) (sporadic). Management strategies are often patient specific because of the variable and unpredictable course. No study has summarized the effect of treatment strategies on visual outcomes in the subset of pediatric patients with sporadic OPG.

We conducted a systematic review to determine the nature of visual outcomes in pediatric patients with sporadic, non-NF1-associated OPG using the PubMed, Embase, Scopus, Cochrane, and CINAHL Plus databases. Visual outcomes were categorized as improved, unchanged, or deteriorated.

Of 1316 results, 31 articles were included. Treatment indications are unknown with full clinical detail. A total of 45.2% (14/31) reported deteriorated outcomes after treatment, 35.5% (11/31) no change, and 19.4% (6/31) improvement. Of radiotherapy studies, 50.0% (4/8) found no change, 37.5% (3/8) deterioration, and 12.5% (1/8) improvement. Of chemotherapy studies, 35.7% (5/14) each showed improvement and deterioration, whereas 28.6% (4/14) showed no change. Of surgical studies, 62.5% (5/8) indicated deterioration, and 37/5% (3/8) indicated no change. The singular study examining observation reported deterioration in visual outcomes. Factors associated with poor visual outcomes included signs and symptoms of visual decline at presentation, involvement of the intraorbital optic nerve, and intracranial hypertension requiring surgery. Causality cannot be determined from systematic review.

Most studies showed that vision in pediatric patients with sporadic OPG is stable to poor after observation, chemotherapy, radiotherapy, or surgery. Chemotherapy may be associated with most favorable visual outcomes.

Neurosurgery is a medical field that requires specialized professionals and equipment, 2 important but scarce resources in low- and middle-income countries. Our goal was to report our experience with the replacement and implementation of linear accelerators with radiosurgery capabilities at "Sociedad de Lucha Contra el Cáncer" (SOLCA) Hospital in Quito, Ecuador, and give some recommendations for future technological replacements (TRs).

Two surveys were performed in SOLCA's radiosurgery department, one before the TR was finalized and one after, consisting of an open and multiple-choice questionnaire. Questions focused on the performance of the new equipment, perceptions regarding the training, and the influence of the pandemic on the whole process. In addition, we share our experience regarding the difficulties and benefits of TR at SOLCA.

The most-reported limitation was lack of training (48%). By the time of the second survey, 95.2% of the staff had already treated patients or planned a radiosurgical ponentially better medical care and accessibility to novel treatments.
Traumatic brain injury (TBI) brings severe mortality and morbidity risk to patients. Predicting the outcome of these patients is necessary for physicians to make suitable treatments to improve prognosis. The aim of this study is to develop a mortality prediction approach using XGBoost (extreme gradient boosting) in moderate-to-severe TBI.

A total of 368 patients hospitalized in West China hospital for TBI with Glasgow Coma Scale (GCS) below 13 were identified. To construct the XGBoost prediction approach, patients were divided into training set and test set with a ratio of 73. A logistic regression prediction model was also constructed and compared with the XGBoost model. Area under the receiver operating characteristic curve, accuracy, sensitivity, and specificity were calculated to compare the prognostic value between XGBoost and logistic regression.

A total of 205 patients suffered a poor outcome with a mortality of 55.7%. Nonsurvivors had a lower GCS (5 vs. 7, P < 0.001) and a higher Injury Severians to evaluate patients with TBI at high risk of poor outcome.
Stereoscopy has been demonstrated to be a useful method of education in the field of anatomy because it allows users to see, in a simulation, the anatomical structures in their actual volume and depth.

Cadaveric specimens preserved under formaldehyde using the Thiel and Klinger techniques have been dissected and photographed in the medical school anatomy laboratory (University Miguel Hernández) for the past 10 years. The photographic material and technique required to capture and project stereoscopic photographs have been described in different fields of surgical neuroanatomy. We used the results from a survey completed by the participants of different training courses to evaluate the utility of the 3-dimensional (3D) method.

A large database of photographs taken of different anatomical regions and approaches of neurosurgical interest was obtained. We have presented some examplesin the form of pairs of photographs in 2-dimensional (2D) format, with explanatory labels, paired with the corresponding 3D photograph in anaglyph format. The survey showed that the lectures that had included 3D photographs were significantly better accepted than the lectures with conventional 2D photographs.

The teaching of basic, academic, and clinical neuroanatomy through the projection of stereoscopic photographs can be useful. The methods of image capture and stereoscopic projection in neuroanatomy, once combined with the necessary theoretical and practical knowledge, can be reproduced at other centers of neuroanatomyteaching.

Studies about the transradial technique and experience with this approach abound in the neurointerventional literature, but studies focusing on patient perspectives and preferences with respect to transfemoral or transradial access are scarce.

Patients from our center who underwent both transradial and transfemoral approaches for diagnostic and interventional cerebral angiograms on distinct occasions between January 2016 and January 2021 were identified and interviewed by phone regarding their experience with these access approaches. The first question was regarding the choice for an eventual next procedure (radial, femoral, or no preference). The second question addressed reasons (pain, bruising, complications, recovery time, mobility, failure of one approach, and comfort associated with puncture of the respective area).

Forty-four patients were interviewed. Thirty-one (70.4%) preferred radial, 9 (20.5%) preferred femoral, and 4 (9.1%) had no preference. Most frequent reasons for radial preference were recovery time (67.7%), bruising (51.6%), and pain (48.4%). Most frequent reasons in femoral preference were pain (55.6%), mobility (33.3%), and failure of the other approach (33.3%). Recovery time (67.7% vs. 22.2%; P= 0.023) and comfort of puncturing the area (45.2% vs. 0%; P= 0.015) were significantly more frequent reasons for radial preference, whereas failure of the other approach (0% vs. 33.3%; P= 0.008) was a significantly more frequent reason for femoral preference.

Most patients preferred the transradial approach. Evaluating the reasons behind their preference can help operators to better understand patient perspectives and improve quality of care.

The objective of the study was to establish a 5-year progression-free survival prediction nomogram using preoperative routine blood tests and magnetic resonance imaging to guide postoperative treatment.

Our study was a retrospective analysis of patients with atypical meningioma admitted into our facility from January 31, 2010, to January 31, 2016. We used single-factor logistic analysis to extract valuable indicators from preoperative blood test results and 3D Slicer software to extract radiomic features from magnetic resonance imaging. The radiomics score was calculated by least absolute shrinkage and selection operator logistic regression analysis. We then combined blood indicators and radiomic signatures to construct a radiomic nomogram image. The performance of the model was evaluated comprehensively using the following three aspects recognition ability, accuracy, and clinical value.

Six significant radiological features were selected through least absolute shrinkage and selection operator logistic regression analysis.
