mparable for the treatment of unresectable HCC in decompensated patients.

A variety of studies have shown rising trends in the occurrence of colorectal cancer in younger patients as opposed to falling trends among older patients aged 55years or more. We hypothesized that the time trends of benign colonic precursor lesions would reveal similar patterns.

The present study was designed to test this hypothesis in a large nationwide sample of the US population undergoing colonoscopy in community-based endoscopy centers.

The Inform Diagnostics database is an electronic repository of histopathologic records of patients distributed throughout the USA. A cross-sectional study analyzed the detection rates of sessile serrated adenomas (SSA), hyperplastic polyps (HP), tubular adenomas (TA), traditional serrated adenomas (TSA), or adenocarcinomas (colorectal cancer, CRC) in 2,910,174 colonoscopies done 2008-2020.

During the 13-year time period, the rate of SSA showed a significant rise, both in patients younger and older than 55years. HP and TA both showed a significant decline during the same time period. The trends of CRC in the older age group decreased significantly between 2008 (or its peak in 2012) and 2020. The trends of CRC in the younger age group increased significantly between 2008 and its peak in 2017.

The age-specific time trends of benign and malignant colonic neoplasia are characterized by dissimilar temporal patterns. Such dissimilarity could suggest that besides a set of shared risk factors that affect all types of colonic neoplasia alike, there is yet another set of environmental risk factors that specifically influence malignant transformation.

Coronavirus disease 19 (COVID-19) causes mild-to-moderate symptoms in most individuals. However, rapid deterioration to severe disease with or without acute respiratory distress syndrome (ARDS) can occur within 1-2 weeks from the onset of symptoms in a proportion of patients. Early identification by risk stratifying such patients who are at risk of severe complications of COVID-19 is of great clinical importance. Computed tomography (CT) is widely available and offers the potential for fast triage, robust, rapid, and minimally invasive diagnosis Ground glass opacities (GGO), crazy-paving pattern (GGO with superimposed septal thickening), and consolidation are the most common chest CT findings in COVID pneumonia. There is growing interest in the prognostic value of baseline chest CT since an early risk stratification of patients with COVID-19 would allow for better resource allocation and could help improve outcomes. Recent studies have demonstrated the utility of baseline chest CT to predict intensive care unit (ICU) admission in patients with COVID-19. Furthermore, developments and progress integrating artificial intelligence (AI) with computer-aided design (CAD) software for diagnostic imaging allow for objective, unbiased, and rapid assessment of CT images.SnRK2 protein kinase family plays an important role in plant response to abiotic stress and has been identified in various plants. This study aimed to identify SnRK2 genes in tobacco and systematically analyze their expression under abscisic acid treatment and abiotic stress. We identified 22 NtSnRK2 members, which were divided into three groups and located on 13 chromosomes, mainly at both ends of the chromosomes; additionally, 11 duplicated NtSnRK2 gene pairs were observed. Phylogenetic analysis showed that these SnRK2 members were divided into three groups in tobacco. The motifs of NtSnRK2 proteins in the same group were highly similar. Subcellular localization indicated that NtSnRK2s in Group3 were present in the nucleus, cytomembrane, and cytoplasm. Gene expression pattern analysis revealed that NtSnRK2 genes played a role in the responses to several abiotic stresses (salt, drought, and low-temperature stress), indicating that they are widely involved in the adaptation of tobacco to adverse environmental conditions.The US South is disproportionately impacted by HIV. Social, cultural, economic, and political characteristics of the South shape access to mental health services leaving adverse impacts on health and wellness outcomes among People Living with HIV. The aim of this paper was to (a) identify meso factors (at individual, organizational and community-level manifestations) which impact mental health services among People living with HIV in the South of those factors and (b) pose community-articulated recommendation and strategies. Through qualitative interviews with People Living with HIV and service providers, this study found that the meso factors of restricted funding and compounding stigma shaped mental health services in the South. Given the disproportionate rate of HIV, lack of mental health care, and landscape of socio-political factors unique to the region, attention to intervenable meso factors and community-based strategies are needed to enhance mental health services and respond to the HIV epidemic in the US South.Glioneuronal and neuronal tumors (GNTs) are rare heterogeneous central nervous system tumors characterized by slow growth and favorable outcomes, but are often associated with diagnostic difficulties. A thorough analysis of three rare and recently recognized GNTs was performed in the context of clinicopathological features and molecular genetic characterization. The current spinal diffuse leptomeningeal glioneuronal tumor (DLGNT) was characterized with oligodendroglioma-like tumor with chromosome 1p/19q codeletion without IDH mutations and KIAA1549BRAF fusion. The current occipital multinodular and vacuolating neuronal tumor (MVNT) was characteristic of the variable-sized vague nodules consisted of gangliocytic tumor cells with intracytoplasmic and pericellular vacuolation and the next-generation sequencing (NGS) revealed MAP2K1 p.Q56_V60del. A diffuse glioneuronal tumor with oligodendroglioma-like features and nuclear clusters (DGONC) of the amygdala was characterized by oligodendroglia-like cells and nuclear clusters, and monosomy 14. From the current cases and literature review, we found that DLGNT commonly occurs in the spinal cord and can make mass and more commonly have KIAA1549BRAF fusion; MVNT is a neoplasm rather than malformation and MAP2K1 deletion is one of the hallmarks of this tumor; although DGONC may require a methylation profile, we can reach a diagnosis through its unique histology, monosomy 14, and exclusion diagnosis without a methylation profile.Land-use changes have a significant impact on the hydrological cycle and non-point source (NPS) pollution discharge and transport. Thus, using dynamic land-use inputs in the simulation models is important. However, there is currently no clear standard for which situation the land-use data should be updated in the models. In this study, we quantified the impacts of land-use change on hydrological and NPS pollution simulation outputs, and analyzed the thresholds for land-use change level and time nodes. The results indicated that the error caused by land-use change had a linear relationship with the land-use change level. The total nitrogen (TN) output error was the most sensitive to land-use change, with a gradient of 0.73. The impact of land-use change on the model outputs was different at different temporal scales. Flow and TN had the highest output errors at a daily scale, while sediment had the highest output error at an annual scale. The threshold analysis results revealed that the land-use change thresholds for the flow, sediment, and TN simulations were 40%, 30%, and 10%, respectively. When the land-use change level exceeded the threshold, the model simulation error increased dramatically. The land-use change time node would also affect the simulation performance, especially for TN. This study initially explored the quantified standard for land-use data updates in the SWAT model. The results could be useful for improving the simulation accuracy of the SWAT model and may provide ideas for follow-up studies.

Standard total mesorectal resection has become an important treatment option for locally advanced or high-risk rectal cancer after neoadjuvant chemo-radiotherapy. 15-27% of patients can achieve pathological complete response (PCR) after neoadjuvant chemo-radiotherapy (nCRT). However, the relationship between PCR and postoperative complications remains an important unsolved problem. The objective of this study was to determine whether PCR was associated with the rate of postoperative complications.

This meta-analysis was implemented following the recommendations from Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We searched electronic literature by PubMed, EMBASE, and Google Scholar. Major outcomes of interest included anastomotic leakage, surgical-site infection, reoperation, and any postoperative complications. Other outcomes comprised postoperative hemorrhage, ileus, and mortality.

Eleven thousand two hundred ninety patients in 9 studies were included in the meta-analysis. The pooled analysis revealed that patients with PCR did not have a higher risk of anastomotic leakage (OR = 1.22, 95% CI 0.92-1.62, p = 0.17), reoperation (OR = 1.13, 95% CI 0.93-1.37, p = 0.22), and any postoperative complications (OR = 1.02, 95% CI 0.91-1.15, p = 0.72) than patients with non-PCR. However, the meta-analysis showed that the PCR group was superior to the non-PCR group in terms of surgical-site infection (9.38% vs. 12.44%OR = 0.68, 95% CI 0.47-0.98; p = 0.04).

PCR might not be related to the occurrence of postoperative complications in rectal cancer patients following nCRT. In addition, PCR might be associated with a lower risk of surgical-site infection.

Keeping this in mind, we surveyed and analyzed the frequency and distribution of microsatellites in the Indian gharial (Gavialis gangeticus) and compared it with American alligator (Alligator mississippiensis) and saltwater crocodile (Crocodylus porosus) to enrich them with genomic resources. The Indian gharial has a low frequency, relative abundance (RA), and relative density (RD) of microsatellites as compared to other crocodilians. RA and RD were positively correlated with the GC content of genomic and transcriptomic sequences. The genomic sequences were dominated by dinucleotide repeats, whereas the transcriptomic sequences had an excess of trinucleotide repeats. Motif conservation studies among the three crocodilians revealed conservation of 69.2% of motifs. Species-specific unique motifs identified in this study could be used as molecular probes for species identification.
