Study Design: Face and content validation of a surgical simulation model.

Objective: Accidental transection of the inferior alveolar nerve (IAN) during bilateral sagittal split osteotomies (BSSO) has a reported incidence of up to 7%, determining important sensory disturbances in patients. Proper repair demands the need of microsurgical anastomosis skills.

Background: Cervical cytology is recommended by WHO as a triage option in HPV-based cervical cancer screening programmes. We assessed the performance of cytology to detect CIN3+ without and with knowledge of HPV positivity.

Methods: Women were screened with cytology and HPV across ESTAMPA study centres in Latin America.

Article Synopsis
  • The text examines the effects of COVID-19 on paracoccidioidomycosis (PCM) in Argentina, noting that 285 confirmed PCM cases were reported from 2018 through three years post-pandemic declaration.
  • It highlights that there was no confirmed link between COVID-19 and PCM, but PCM cases dropped significantly in 2020 due to pandemic-related factors.
  • The pandemic caused delays in PCM diagnosis and treatment due to social isolation and mental health issues, raising concerns about potential underdiagnosis because of symptom overlap and insufficient diagnostic methods.

Introduction: Combined prevention (CP) is considered the key strategy against the HIV epidemic. The objective of the study was to evaluate the perception of risk of HIV infection and the knowledge about the use of antiretrovirals (ARV) for prevention, among patients who attend a Sexually Transmitted Infections (STI) clinic.

Methods: A survey on personal data and perception of risk of HIV infection, knowledge about post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP), was administered to patients at the time of applying doses of penicillin for the treatment of syphilis, or when taking a blood sample for STI diagnosis, between May and December, 2022.

Trypanosoma brucei are protozoan parasites that cause sleeping sickness in humans and nagana in cattle. Inside the mammalian host, a quorum sensing-like mechanism coordinates its differentiation from a slender replicative form into a quiescent stumpy form, limiting growth and activating metabolic pathways that are beneficial to the parasite in the insect host. The post-translational modification of proteins with the Small Ubiquitin-like MOdifier (SUMO) enables dynamic regulation of cellular metabolism.

Article Synopsis
  • * Multi-omics analyses of blood and tissue samples from a clinical trial revealed that higher immune scores correlate with better responses to ICIs, while certain immune cells, like regulatory T cells, negatively impact survival.
  • * Variations in immune cell density and proximity to tumor cells influence survival outcomes, and soluble proteins found in the blood could serve as indicators for treatment effectiveness and overall survival in SqNSCLC patients.

Emerging life-threatening multidrug-resistant (MDR) species such as the species complex, (sin. ), and other species are considered as an increasing risk for human health in the near future. (1) Background: Many studies have emphasized that the increase in drug resistance can be associated with several virulence factors in and its knowledge is also essential in developing new antifungal strategies.

The clinical quality and longevity of increasingly popular resin-bonded CAD/CAM ceramic restorations depends greatly on the strength and durability of the resin-ceramic bond. With a diverse array of ceramic materials available, the choice of ceramic bonding protocol is highly influenced by the specific ceramic's type and composition. Typically, this protocol encompasses a surface pretreatment step followed by the application of a priming agent.

Cancer disease is one of the most important pathologies in the world, as it causes the death of millions of people, and the cure of this disease is limited in most cases. Rapid spread is one of the most important features of this disease, so many efforts are focused on its early-stage detection and localization. Medicine has made numerous advances in the recent decades with the help of artificial intelligence (AI), reducing costs and saving time.

Histopathologic whole-slide images (WSI) are generally considered the gold standard for cancer diagnosis and prognosis. Survival prediction based on WSI has recently attracted substantial attention. Nevertheless, it remains a central challenge owing to the inherent difficulties of predicting patient prognosis and effectively extracting informative survival-specific representations from WSI with highly compounded gigapixels.

Background: Cervical cytology remains widely used as the initial tool in cervical cancer screening worldwide. WHO guidelines recommend replacing cytology with primary HPV testing to reach cervical cancer elimination goals. We assessed the performance of cytology and high-risk HPV testing to detect cervical precancer, cervical intraepithelial neoplasia (CIN) grade 3 or worse (CIN3+) among women aged 30-64 years participating in the ESTAMPA study.

Article Synopsis
  • * Lung adenocarcinoma (ADC) is the most common type of lung cancer, with atypical adenomatous hyperplasia being a key precursor that can progress to more serious forms.
  • * By using advanced deep learning techniques on common histopathology images, researchers extracted important features that show changes in cell types as lung cancer develops, suggesting that pathomics could be a cost-effective method to study lung cancer evolution.

Astrocytes play a critical role in the maintenance of a healthy central nervous system and astrocyte dysfunction has been implicated in various neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). There is compelling evidence that mouse and human ALS and ALS/FTD astrocytes can reduce the number of healthy wild-type motoneurons (MNs) in co-cultures or after treatment with astrocyte conditioned media (ACM), independently of their genotype. A growing number of studies have shown that soluble toxic factor(s) in the ACM cause non-cell autonomous MN death, including our recent identification of inorganic polyphosphate (polyP) that is excessively released from mouse primary astrocytes (, , and ) and human induced pluripotent stem cells (iPSC)-derived astrocytes () to kill MNs.

Pisco is an alcoholic beverage obtained from grape juice distillation. Considered the flagship drink of Peru, it is produced following strict and specific quality standards. In this work, sensing results for volatile compounds in pisco, obtained with an electronic nose, were analyzed through the application of machine learning algorithms for the differentiation of pisco varieties.

Multimodal emotion recognition implies the use of different resources and techniques for identifying and recognizing human emotions. A variety of data sources such as faces, speeches, voices, texts and others have to be processed simultaneously for this recognition task. However, most of the techniques, which are based mainly on Deep Learning, are trained using datasets designed and built in controlled conditions, making their applicability in real contexts with real conditions more difficult.

Information on paracoccidioidomycosis (PCM) in Argentina is fragmented and has historically been based on estimates, supported only by a series of a few reported cases. Considering the lack of global information, a national multicentric study in order to carry out a more comprehensive analysis was warranted. We present a data analysis including demographic and clinical aspects of a historical series of 466 cases recorded over 10 years (2012-2021).

The purpose of this study was to assess the efficacy of a combined training program (CTP) in reducing the effects of dual tasking on the temporal parameters and kinematics of gait, as compared with single-task gait. A controlled, randomized, intervention study was performed in an intervention group and a control group. The intervention group attended three weekly CTP sessions for 24 weeks.

Malassezia sympodialis and Malassezia furfur are recognized as an important part of the human and animals healthy skin microbiota, but also as an opportunistic fungus due to their association with a broad spectrum of skin and systemic infections. Human skin infections associated with Malassezia spp. are often chronic, recurrent, and topical or oral azole treatments are challenging with not always successful outcomes.
