This study aimed to implement lupus anticoagulant (LAC) detection techniques according to the International Society on Thrombosis and Hemostasis (ISTH) recommendations, in the Biological Laboratory of the Maternity and Neonatal Medicine Center (Monastir, Tunisia) and to evaluate the profile and the prevalence of antiphospholipid antibodies (aPL) in the obstetric antiphospholipid syndrome (OAPS).

We collected two groups a "case group" (53 women who presented one or more obstetrical criteria of APS) and a "control group." LAC was detected following the four steps recommended by ISTH 2009. Anticardiolipin (aCL) and antibeta-2-glycoprotein I (aβ2GPI) antibodies testing were performed by enzyme-linked immunosorbent assay (ELISA).

aPL were found in five patients three patients with isolated LAC, one patient with isolated IgG aCL, and one patient with triple positivity (LAC, aCL IgM, aβ2GPI IgM). Concerning LAC, 13 (24.52%) of 53 patients had a screening step with at least one positive test. The mixing step was positive in four patients and then confirmed in the confirmatory test. Thus, the prevalence of LAC in our study group is 7.54%. Surprisingly, among these positive patients, one patient had an associated combined factor V (FV) and factor VIII (FVIII) deficiency.

There is no single test and no algorithm that can detect all types of LAC. It seems that the recent 2020 ISTH algorithm allows a better detection of low activity LAC than the 2009 algorithm. In our study, the most frequently identified antiphospholipid antibodies were LAC more than aCL and aβ2GPI.

We evaluated the impact of Gleason pattern 5 presence on prognosis among de novo metastatic hormone-sensitive prostate cancer patients with a Gleason score ≥8.

The data of 559 patients diagnosed as metastatic hormone-sensitive prostate cancer with a Gleason score ≥8, who were initially treated with androgen deprivation therapy from 2008 to 2016, were retrospectively collected. Patients were divided into two groups as high and low volume based on the CHAARTED trial criteria.

The median overall survival of the 559 metastatic hormone-sensitive prostate cancer patients with Gleason score ≥8 was 70 months, with a median follow-up period of 36 months. Gleason pattern 5 was confirmed in 341 patients (61.0%), in which primary Gleason pattern 5 was confirmed in 164 patients (29.3%). The number of patients with high metastatic volume group was 363 (64.9%). In total and high metastatic volume groups, hemoglobin and lactate dehydrogenase were significant factors for predicting overall survival, but both Gleason patry Gleason pattern 5 was a poor prognostic factor, which might show a separate treatment option for this group.Pervasive transcription of the human genome generates a massive amount of noncoding RNAs (ncRNAs) that lack protein-coding potential but play crucial roles in development, differentiation, and tumorigenesis. To achieve these biological functions, ncRNAs must first fold into intricate structures via intramolecular RNA-RNA interactions (RRIs) and then interact with different RNA substrates via intermolecular RRIs. RRIs are usually facilitated, stabilized, or mediated by RNA-binding proteins. With this guiding principle, several protein-based high-throughput methods have been developed for unbiased mapping of defined or all RNA-binding protein-mediated RRIs in various species and cell lines. In addition, some chemical-based approaches are also powerful to detect RRIs globally based on the fact that RNA duplex can be cross-linked by psoralen or its derivative 4'-aminomethyltrioxsalen. These efforts have significantly expanded our understanding of RRIs in determining the specificity and variability of gene regulation. Here, we review the current knowledge of the regulatory roles of RRI, focusing on their emerging roles in transcriptional regulation and nuclear body formation.

The Multicultural Identity Styles Scale proposes two identity strategies, hybrid identity style (HIS) and alternating identity style (AIS) as processes through which individuals negotiate their bicultural identities. We test a model whereby perceived diversity norms predict bicultural identity consolidation directly and indirectly via HIS in samples of British (n = 195) and non-British (n = 181) Australians. Participants (56.9% females, mean age = 41.52) completed an online survey on perceived diversity norms, the MISS and bicultural identity consolidation. Results showed that for non-British Australians, there was a positive indirect effect of perceived multiculturalism norms on bicultural identity consolidation via HIS. Perceived assimilation was directly (and negatively) linked to bicultural identity consolidation but indirectly via HIS. In British Australians only perceived polyculturalism was directly and indirectly associated to bicultural identity consolidation via HIS, whereas perceived multiculturalism and assimilation norms were negatively associated to bicultural identity consolidation. The results are discussed in terms of the differential roles of perceived diversity norms on bicultural identity processes and consolidation relative to the nature of the cultural group.Cerebellar liponeurocytoma (CL) is an unusual tumor, histologically composed of a mixture of small to medium-sized, rounded neurocytic cells and a variable lipomatous component. Although CL was originally considered as a subtype of medulloblastoma, subsequent molecular studies demonstrated that this tumor was a distinct entity, exhibiting the tumor protein p53 gene (TP53) missense mutations in 20% of cases, chromosome 17 deletion, and the absence of mutations in the adenomatous polyposis coli gene (APC), the protein patched homolog gene (PTCH), the kinase insert domain receptor gene (KDR), and the β-catenin gene (CTNNB). Apart from these molecular features, little is known about the pathogenesis and the genetic landscape of CL to date. In order to characterize the mutational landscape of CL and identify alterations that are driving tumorigenesis, we report a series of three cases, including one recurrent tumor, analysed by next-generation sequencing (NGS), which identified a total of 22 variants, of which four were missense mutations, nine were synonymous variants, and nine were located on intronic regions. In particular, DNA sequencing identified missense mutations in APC, KDR, and TP53 that could be implicated in promoting tumor progression and angiogenesis of CL. Furthermore, the NGS analysis revealed that recurrent CL did not have additional genetic changes compared with the primary tumor. Moreover, the high frequencies of detected mutations suggested that the identified alterations are germline variants. Indeed, an additional NGS on the genomic DNA obtained from one of the three patients confirmed the presence of the variants in the germline DNA. In conclusion, the obtained data support the hypothesis that CL is a distinct pathological entity that does not show specific somatic alterations driving tumorigenesis.Dermoscopy of mycetoma has white structures as the predominant feature, while white scale and yellowish structures were also consistent in our findings with available literature.
Ulceration is regarded as an adverse prognostic factor and is used together with tumour thickness to subcategorize patients with cutaneous melanoma. However, the prognostic impact of ulceration in acral melanoma (AM) is controversial.

To assess the prognostic impact of ulceration in AM and the variability across different Breslow thicknesses and clinical stages.

A multicentre retrospective study of patients diagnosed with AM between January 2000 and December 2017. Differences in melanoma-specific survival (MSS) between patients with and without ulceration were assessed using the multivariable Cox proportional hazards model and log-rank test.

Among 1053 enrolled patients, 62.6% had ulceration. After a median follow-up of 61 months, patients with ulceration had a lower median MSS than those without 66.1 months, 95% confidence interval (CI) 60.0-86.0 vs. not reached; hazard ratio 1.41, 95% CI 1.09-1.82; P = 0.012. Among patients with thin (≤ 1 mm) melanoma, the survival curves of patients with vs. withouto the America Joint Committee on Cancer melanoma staging system. As one distinctive subtype of cutaneous melanoma, acral melanoma (AM) is characterized by poor survival outcomes due to delayed diagnosis and a high prevalence of negative prognostic and genetic features. The prognostic impact of ulceration in AM is still controversial. What does this study add? This was the first large-scale study to assess the prognostic and staging values of ulceration in patients with AM. Ulceration has a significant effect on prognosis for patients with thin (≤1 mm) melanoma, but no association between ulceration and survival was found in intermediate/thick or stage III AM. These findings should be considered when using ulceration-based staging systems.
 Spinal subdural abscesses (SSAs) are rare and have a poor prognosis, especially when they are diagnosed late. selleck compound In the literature, most cases of SSAs have been reported as case reports and small case series. In this study, we aimed to evaluate the surgical outcomes of four consecutive SSA patients.

 In this retrospective study, we reviewed the medical charts of four SSA patients who underwent surgical intervention at two neurosurgical centers from September 2012 to September 2019.

 Our series comprised four patients (three females and one male) with SSA (intradural-extramedullary) who were treated surgically. Holocord SSA was observed in two patients. The mean age was 15.1 ± 17.1 years. Unsteady gait and weakness of legs was the presenting symptom in all patients. The mean preoperative course was 5.3 ± 3.4 weeks. The causative pathogens were methicillin-resistant
(MRSA),
, and
. In the fourth case, the pathogen was non-
. In the 44th postoperative month, the patient underwent surgery for an intramedullary abscess. The causative pathogen was
. Except for one adolescent male who was paraplegic at presentation, improvement was observed in all patients at their last follow-up after 54.0 ± 35.9 months after surgery.

 Early diagnosis and urgent surgical intervention are essential for a good prognosis in SSA cases. We recommend drainage followed by appropriate antibiotics.
