Odor threshold detection was more affected by COVID-19 compared to odor identification.
Five weeks after developing sudden chemosensory loss due to COVID-19, a high proportion of patients were dysosmic and showed signs of low nasal cooling sensitivity, whereas most of them had normal taste function. SARS-CoV-2 affected mainly odor thresholds, possibly suggesting that the major cause of loss of smell lies at the level of the olfactory neuroepithelium, rather than in the central nervous system.

The purpose of the present study was to compare the voice of choir singers before and after 60min of singing and after an absolute rest.
Twenty-one female choir singers aged on average 26.59years, with experience in choir singing of at least one year were instructed to emit the vowel /a/ before and after singing and after a vocal rest of 30min for an analysis of acoustic measures, and for the evaluation of their tactile-kinesthetic self-perception. Vocal warm-up was performed for 10min. The participants were instructed to sing the "Ave Verum" music continuously for 60min.
f0 (p = 0.0001) and Flo (p = 0.0002) increased after the singing test and were reduced after the vocal rest, in contrast to Fhi (p = 0.001), which continued to be increased compared to the pre-test measure even after the vocal rest. The vAm parameter (p = 0.05) was reduced after continuous singing and rest. All self-evaluation symptoms increased after the continuous singing task and were reduced after the 30min rest, except for complaints of low voice, pain when swallowing and cough/throat clearing.
60min of continuous use of the singing voice induced signs of vocal fatigue with an increase in f0, with improvement of symptoms and a reduction of f0 occurring after 30min of vocal rest.

We present the case of an eight-year-old child who sustained a penetrating injury through the right anterior thorax. Thoracic CT showed the arrow tip extending through the spinal canal at T6. Neurologic examination revealed no motor or sensory function below T6. The arrow was surgically removed without complications through an anterior-only approach. MRI on post-operative day (POD) 4 showed focal T2 hyperintensity at the T6 spinal cord. Patient was discharged on POD33 with an American Spinal Injury Association (ASIA)-D score and trace voluntary control over bowel and bladder function. Remarkably, four months later, he had near normal bowel and bladder function, with near-intact lower extremity strength and self-sustained ambulation. Follow-up imaging revealed hemicord formation at the level of injury. We review our case of penetrating spinal cord injury in a child and similar reports in the literature. Penetrating thoracic spinal cord trauma portends poor clinical outcomes, particularly when employing available adult prognostic spinal cord injury scoring metrics. Incomplete spinal cord injury, and often-associated spinal shock, can mimic a complete injury-as in our patient, which improved to near-complete motor and sensory restoration of function and resulted in the formation of a split hemicord. This case represents a unique penetrating spinal cord injury with remarkable neurologic recovery, which would advocate against definitive early prognostication in the pediatric population.
Children diagnosed with a brain tumor (BT) in the first years of their life are at high risk of cognitive and neuropsychological problems, more school difficulties, and an increased need for educational support. To improve this condition, it will be beneficial to be able to identify the neuropsychological variables that are early predictors of school competences at later ages.
We longitudinally assessed 30 school-age BT children with a diagnosis before the age of 5 who were administered cognitive and neuropsychological evaluations before entering school or in the first 2 school years and who were followed up for academic performance at least one year after the first evaluation. A discriminant function analysis was conducted to detect the early neuropsychological profile that best predicted those children who turned out to need school support or not; we tested 5 block multiple regression models, one for each academic variable entering as predictors the neuropsychological variables that significantly discriminated the two groups.
A total of 93.3% of the cases were correctly classified according to the discriminant function in "with vs. without" educational support. Visual attention abilities were highly correlated with resulting school problems, both for reading (accuracy and speed) and math (operations) at school age.
Analysis provided evidence that the early neuropsychological profile may predict academic difficulties for both reading and math at school age and that visual attention seems to play an important role in both these academic abilities, allowing clinicians to identify children with major difficulties in/from early years and to intervene beforehand.

In addition, loss of phosphatase and tensin homologue (PTEN) was shown to be associated with therapy resistance in CRC. Our primary aim was to assess specific genetic alterations including APC and PTEN in a large series of UrC samples in order to identify clinically significant genomic alterations. We analyzed a total of 40 UrC cases. Targeted 5-gene (APC, PTEN, DICER1, PRKAR1A, TSHR, WRN) panel sequencing was performed on the Illumina MiSeq platform (n = 34). In addition, ß-catenin (n = 38) and PTEN (n = 30) expressions were assessed by immunohistochemistry. APC and PTEN genes were affected in 15% (5/34) and 6% (2/34) of cases. Two of five APC alterations (p.Y1075*, p.K1199*) were truncating pathogenic mutations. One of the two PTEN variants was a pathogenic frameshift insertion (p.C211fs). In 29% (11/38) of samples, at least some weak nuclear ß-catenin immunostaining was detected and PTEN loss was observed in 20% (6/30) of samples. The low prevalence of APC mutations in UrC represents a characteristic difference to CRC. Based on APC and ß-catenin results, the Wnt pathway seems to be rarely affected in UrC. Considering the formerly described involvement of PTEN protein loss in anti-EGFR therapy-resistance its immunohistochemical testing may have therapeutic relevance.
To evaluate with computed tomography (CT) the incidence of anchor-related osteolysis after implantation of two types of all-suture anchors for the management of labral lesions in shoulder instability.
Single-cohort, observational study with 12-month follow-up. Thirty-three participants (27 males/6 females; age 38.3years [SD 11.3]) with anterior labral lesions in which 143 all-suture anchors (71 Iconix 1.4mm and 72 Suturefix 1.7mm) were implanted were evaluated with a CT performed a mean of 15.4 [3.85] months after surgery. The volume of the bone defects was measured in the CT. Every anchor was classified into one of four groups (1) no bone defect. (2) Partial bone defect (defects smaller than the drill used for anchor placement). (3) Tunnel enlargement (defects larger than the drill volume but smaller than twice that volume). (4) Cystic lesion (defects larger than twice the drill volume).
No bone defect was identified in 16 anchors (11.2%, [95% CI 6.5-17.5%]). A partial bone defect was found in 84 anchoely (11%) or partially (59%) with bone. Tunnel enlargement will develop in 30% of anchors. No cystic defects larger than 0.125 cm3 were observed. There is a low risk that all-suture anchors cause significant osteolytic bone defects in the glenoid. These implants can be used safely. Level of evidence IV.NLRP3 pathway plays a vital role in the pathogenesis of different human cancers but still the regulation of NLRP3 pathway largely unknown. Therefore, we examined the levels of NLRP3 and its downstream components (caspase-1 and IL-1β) and its relationship with histone modifiers in renal cancer pathogenesis. Total 30 cases of clear cell renal cell carcinoma (ccRCC), were studied for NLRP3, caspase-1 and IL-1β expression using real-time PCR, which showed the augmented levels of all the three components of NLRP3 inflammasome pathway in ccRCC. Next, role of the FAD dependent monoamine oxidases (LSD2) and jumonji C (JmjC)-domain-containing, iron-dependent dioxygenases (KDM5A) histone demethylases were evaluated in regulation of NLRP3 inflammasome pathway in-vitro using RCC cell line. It was observed that silencing of KDM5A didn't alter the levels of neither of the NLRP3 component but inhibition of LSD2 showed significant effect on NLRP3 expression while no change in caspase-1 and IL-1β levels. This study suggests that rather LSD2 not KDM5A lysine demethylase family might be involved in the regulation of NLRP3 inflammasome in cancer cells which could be useful for deciphering the future therapeutic targets for the disease.Debate regarding the best way to test and measure eyewitness memory has dominated the eyewitness literature for more than 30 years. We argue that resolution of this debate requires the development and application of appropriate measurement models. In this study we developed models of simultaneous and sequential lineup presentations and used these to compare these procedures in terms of underlying discriminability and response bias, thereby testing a key prediction of diagnostic feature detection theory, that underlying discriminability should be greater for simultaneous than for stopping-rule sequential lineups. We fit the models to the corpus of studies originally described by Palmer and Brewer (2012, Law and Human Behavior, 36(3), 247-255), to data from a new experiment and to eight recent studies comparing simultaneous and sequential lineups. We found that although responses tended to be more conservative for sequential lineups there was little or no difference in underlying discriminability between the two procedures.
