Emerging manifestations of artificial intelligence (AI) have featured prominently in virtually all industries and facets of our lives. Within the radiology literature, AI has shown great promise in improving and augmenting radiologist workflow. In pediatric imaging, while greatest AI inroads have been made in musculoskeletal radiographs, there are certainly opportunities within thoracoabdominal MRI for AI to add significant value. In this paper, we briefly review non-interpretive and interpretive data science, with emphasis on potential avenues for advancement in pediatric body MRI based on similar work in adults. The discussion focuses on MRI image optimization, abdominal organ segmentation, and osseous lesion detection encountered during body MRI in children.Thalassemia is a common genetic disorder. We aimed to present thalassemia mutation data that covers a period of 7 years from the Mediterranean region of Turkey by comparing with hemoglobin indices and to contribute to prenatal diagnosis and genetic counseling studies which should be decided very quickly. In this study, in which a retrospective archive was scanned, the cases were first grouped as α and β thalassemia, and then β thalassemia mutations were examined in a total of 5 groups as UTR-Pro, Codon, IVS, β0, and β+. We have reached the family of the proband that analyzed their Hb indices and genetic mutation. All mutations were statistically compared with Hb indices, HbF, and HbA2. We have identified two new β thalassemia mutations that have the feature of not being defined previously [HBBC*62 A>G. (3'UTR+1536 A>G) and HBBC*1 G>A (3'UTR+1475 G>A)]. The most commonly encountered 23 mutations account for 74.7% of all mutations which is unlike the literature. In the β thalassemia group, 73 different mutations were detected. The most common β thalassemia mutation was HBB c.93-21 G>A (IVS I-110 G>A) with a frequency of 19.72%. A statistically significant difference was found when comparing the mutation groups with Hb indices. We think that it may be useful to evaluate the mutations we have newly identified too together with the Hb indices especially in evaluating the carriers of thalassemia and it will contribute to prenatal diagnosis and genetic counseling studies which should be decided very quickly.
Recurrent laryngeal nerve (RLN) paralysis is one of the most devastating complications after thyroidectomy. Thyroid reoperation is a great challenge for surgeons due to anatomical distortion and fibrosis and associated with a higher risk of RLN injury. In this study, we aimed to compare stimulating dissector (SD) with intermittent stimulating probe (ISP) in thyroid reoperations. This study is the first one which compares the impact of different nerve stimulating devices in thyroid reoperations.
Included in this randomized prospective study were patients who had a bilateral subtotal thyroidectomy and would undergo a completion thyroidectomy due to a diagnosis of thyroid papillary cancer between January 2015 and January 2017. Patients were divided into two groups as SD group and ISP group. Age, sex, nerve amplitudes, latencies, the first identification time of RLN and complications were compared in both groups.
A total of 32 patients, 16 in both groups, were included in the study. The demographics, nerve signal amplitudes and latencies were similar in both groups (p > 0.05). The mean RLN identification time in the SD group was 17.4 ± 4.3min, which was significantly shorter than those in the ISP group (mean 21.3 ± 3.9) (p = 0.014).
The first identification of RLN in the thyroid reoperations was faster with the use of SD than with the use of the ISP. Since the electromyographic amplitudes of RLN and vagus nerve with using SD were similar to the bipolar ISP, SD can be used safely for thyroid reoperations.

However, the capacity of this self-healing process can be exhausted by a variety of different liver diseases, such as alcoholic liver damage, viral hepatitis, or hepatocellular carcinoma. Over time, all these diseases generally lead to progressive liver failure that can become fatal if left untreated. Thus, a great effort has been directed towards the development of innovative therapies. The most recently discovered therapies often involve modifying the patient's immune system to enhance a beneficial immune response. Current data suggest that, among others, the cytokine IL-22 might be a promising therapeutical candidate. IL-22 and its endogenous antagonist, IL-22BP, have been under thorough scientific investigation for nearly 20 years. While IL-22 is mainly produced by TH22 cells, ILC3s, NKT cells, or γδ T cells, sources of IL-22BP include dendritic cells, eosinophils, and CD4+ cells. In many settings, IL-22 was shown to promote regenerative potential and, thus, could protect tissues from pathogens and damage. However, the effects of IL-22 during carcinogenesis are more ambiguous and depend on the tumor entity and microenvironment. In line with its capabilities of neutralizing IL-22 in vivo, IL-22BP possesses often, but not always, an inverse expression pattern compared to its ligand. In this comprehensive review, we will summarize past and current findings regarding the roles of IL-22 and IL-22BP in liver diseases with a particular focus on the leading causes of advanced liver failure, namely, liver infections, liver damage, and liver malignancies.Arbuscular mycorrhizal fungi (AMF) spore density and root colonization are considered sensitive to host species and abiotic factors such as climate and soil. However, there is a knowledge gap about how fragmented native forest remnants might contribute to AMF conservation, what is the AMF spore density and root colonization, and to what extent climate change, particularly warming, might impact AMF. The aim of the study was to quantify the AMF spore density and root colonization along altitudinal gradients in three agro-ecological zones of nine church forests in northern Ethiopia. Data were collected from 45 plots. All the surveyed church forest species were colonized by AMF. However, we found a significant (p less then 0.05) decrease in root colonization and AMF abundance in forests at high elevation. The topsoil had significantly (p less then 0.05) higher root colonization and AMF abundance than subsurface soil. We found strong negative correlations between altitude and both spore density and root colonization and soil fertility. While we cannot separate whether spore density was temperature or soil limited, we can demonstrate the importance of conserving certain tree species, particularly Ficus species, which harbor high spore densities, in both lowland and midland church forests. In the highland, no Ficus species were found. However, Hagenia abyssinica, another Rosales, had the highest spore density in the highland ecoregion.
Hyaluronic acid (HA) fillers have been widely used in humans since 1958 because of their biomedical safety. BMS303141 Restylane
was introduced in the1990s as a favorable temporary filler option for facial augmentation. Subsequently, many new HA filler products, including the Sardenyashape
, have been introduced, but comparative studies of these products are limited. Here, we compared tolerability (wrinkle severity rating scale, WSRS), pain (visual analog scale, VAS score), satisfaction (global esthetic improvement scale, GAIS), and safety of a new monophasic HA (MHA) filler (Sardenyashape
) containing lidocaine, used to correct nasolabial folds (NLFs), with those of biphasic HA (BHA) filler (Restylane LYFT
) containing lidocaine.
We enrolled 96 participants with visible NLFs in this randomized, double-blind, single-center clinical study. Participants were injected with a new MHA filler in one NLF and a BHA filler and were reassessed for cosmetic changes at 8 and 24 weeks. Wrinkle severity was assessed using thEvidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266 .
Aging affects the face in all its dimensions. However, more has been published about the improvement of the periocular, midface, and perioral aging changes. We believe the profile view, particularly the preauricular area, is of great value when assessing the need for facial contouring procedures, as well as their effectiveness.
To develop and evaluate a classification based on the aging changes around the preauricular area, which aims to provide an objective direction to the appropriate treatment method.
All patients who attended the clinic for different aesthetic procedures between June 2019 and January 2020 were photographed. Two non-treating dermatologists and two non-treating plastic surgeons were asked to evaluate the perceived aging of the preauricular area using a three-point grading system. The assessment of each photograph was made once by each evaluator, and the inter-rater correlation was calculated.
A total of 158 profile pictures of the preauricular area of 158 patients were evaluated by that authors assign a level of evidence to each article.

Magnetic resonance spectroscopy (MRS) provides non-invasive information about metabolic features in different regions of the brain affected by mesial temporal sclerosis (MTS).
To review articles analyzing the most common alterations in biochemical parameters in MTS and the applications of MRS in presurgical assessment.
We undertook a systematic literature search for MRS in MTS in PubMed, SCOPUS, and Cochrane based on the MESH terms ""Magnetic Resonance Spectroscopy", "Proton Magnetic Resonance Spectroscopy", "Carbon-13 Magnetic Resonance Spectroscopy", "1H-MRS", "31P-MRS", "mesial temporal sclerosis", "hippocampal sclerosis", "mesial temporal seizure", and "mesial temporal epilepsy".
Of the initial 134 articles found, 30 were selected after the exclusion process. Of these, 13 detected a decrease in N-acetylaspartate (NAA), 9 showed a decreased in the ratio NAA/Cho+Cr, and 8 demonstrated a decreased in the ratio NAA/Cr, all of them in the ipsilateral hippocampus. Nine studies also found reduced NAA levels in extrahippocampal regions.
The main findings were a decrease in NAA in the ipsilateral hippocampus. In addition, NAA levels were low outside the hippocampus so MTS could be a more extensive disease. Patients without MTS also presented a decrease in NAA in the ipsilateral hippocampus although NAA was even lower in the MTS patients. Thus, MRS could be useful in the presurgical evaluation to locate the epileptogenic focus, but not specific for the diagnosis of MTS.
