Antibiotics with antibiofilm activity - rifampicin and beyond.

The management of prosthetic joint infections is a complex and multilayered process that is additionally complicated by the formation of bacterial biofilm. Foreign material provides the ideal grounds for the development of an intricate matrix that hinders treatment and creates a difficult environment for antibiotics to act. Surgical intervention is often warranted but requires appropriate adjunctive therapy.

Ovarian cancer ascites proteomic profile reflects metabolic changes during disease progression.

Ovarian cancer (OC) patients develop ascites, an accumulation of ascitic fluid in the peritoneal cavity anda sign of tumour dissemination within the peritoneal cavity. This body fluid is under-researched, mainly regarding the ascites formed during tumour progression that have no diagnostic value and, therefore, are discarded. We performed a discovery proteomics study to identify new biomarkers in the ascites supernatant of OC patients.

Deciphering the Molecular Mechanisms behind Drug Resistance in Ovarian Cancer to Unlock Efficient Treatment Options.

Ovarian cancer is a highly lethal form of gynecological cancer. This disease often goes undetected until advanced stages, resulting in high morbidity and mortality rates. Unfortunately, many patients experience relapse and succumb to the disease due to the emergence of drug resistance that significantly limits the effectiveness of currently available oncological treatments.

Treatment of Psoriasis Patients with Latent Tuberculosis Using IL-17 and IL-23 Inhibitors: A Retrospective, Multinational, Multicentre Study.

Background: Tuberculosis has a major global impact. Immunocompetent hosts usually control this disease, resulting in an asymptomatic latent tuberculosis infection (LTBI). Because TNF inhibitors increase the risk of tuberculosis reactivation, current guidelines recommend tuberculosis screening before starting any biologic drug, and chemoprophylaxis if LTBI is diagnosed.

Long-term patient-reported outcomes from monarchE: Abemaciclib plus endocrine therapy as adjuvant therapy for HR+, HER2-, node-positive, high-risk, early breast cancer.

Background: In monarchE, abemaciclib demonstrated a sustained benefit in invasive disease-free survival and a tolerable safety profile at 42-months median follow-up. With no expected disease-related symptoms, therapies in the adjuvant setting should preserve quality of life (QoL). With all patients off abemaciclib, we report updated patient-reported outcomes (PROs) for the full 2-year treatment period and follow-up.

Metastatic Cervical Cancer: A Case That Recalls the Importance of a Multidisciplinary Approach.

Cervical cancer is one of the most common neoplasms in women. Usually, this cancer is only symptomatic in advanced stages and is associated with a poor prognosis. We present the case of a 34-year-old woman with localized cervical cancer at diagnosis treated with surgery in 2011.

Interval between two-stage exchanges: what is optimal and how do you know?

Background: Two-stage exchange arthroplasty remains the most popular option for the treatment of chronic periprosthetic joint infection (PJI). Determining infection eradication and optimal timing of reimplantation can be challenging. Information to allow for a truly informed evidence-based decision is scarce.

Dual beta-lactam treatment: Pros and cons.

The battle against microscopic pathogens has always baffled the scientific community. Nowadays, multidrug-resistant microorganisms lead to high in-hospital mortality, increased hospital stays, and high health-related costs. Treating infections due to these high-resistance pathogens with a low number of antibiotic molecules creates the need for new strategies.

Learning hybrid locomotion skills-Learn to exploit residual actions and modulate model-based gait control.

This work has developed a hybrid framework that combines machine learning and control approaches for legged robots to achieve new capabilities of balancing against external perturbations. The framework embeds a kernel which is a model-based, full parametric closed-loop and analytical controller as the gait pattern generator. On top of that, a neural network with symmetric partial data augmentation learns to automatically adjust the parameters for the gait kernel, and also generate compensatory actions for all joints, thus significantly augmenting the stability under unexpected perturbations.

Simple and inexpensive synovial fluid biomarkers for the diagnosis of prosthetic joint infection according to the new EBJIS definition.

: diagnosis of periprosthetic joint infection (PJI) is challenging, as no single test has absolute accuracy. The purpose of this study was to assess the utility of different simple synovial biomarkers in the diagnosis of PJI as defined by the European Bone and Joint Infection Society (EBJIS). : we retrospectively identified all patients undergoing revision hip or knee arthroplasty from 2013 to 2019 on our prospectively maintained database.

Guideline for management of septic arthritis in native joints (SANJO).

This clinical guideline is intended for use by orthopedic surgeons and physicians who care for patients with possible or documented septic arthritis of a native joint (SANJO). It includes evidence and opinion-based recommendations for the diagnosis and management of patients with SANJO.

Bridging the Gap Between Family Medicine and Adolescents: Creating Opportunities Through Sex Education.

Introduction: Despite school sex education programs defined by law and a national healthcare service with dedicated family planning appointments, the number of teenage pregnancies in Portugal remains significant. The implementation of these programs has been found lacking and a disconnection between adolescents and primary healthcare has been identified. Adolescents have low literacy in contraception, with males being less involved and informed.

[Intrahospital Protocol for the Management of COVID-19 Disease in Adults].

The COVID-19 pandemic is currently responsible for over 526 million infections and over 6.3 million deaths. As a new disease, the number of papers on the subject is extensive, motivating considerable heterogeneity in its approach.

Prognostic Factors and Survival According to Tumor Subtype in Women With Breast Cancer Brain Metastases.

Breast cancer (BC) is the second most cause of central nervous system (CNS) metastases. Studies report that almost one third of patients (pts) with triple-negative, one-third with human epidermal growth factor receptor 2 (HER2)-positive and 15% of those with hormone receptor-positive, HER2-negative metastatic breast cancer will develop brain metastases. It is known that the development of symptomatic brain metastases in women with advanced breast cancer is associated with poor prognosis, irrespective of local and systemic treatments.

Do Not Forget Poly (Adenosine Diphosphate-Ribose) Polymerase Inhibitors in Ovarian Carcinosarcoma.

Ovarian carcinosarcoma (OCS) is a rare entity with a poor prognosis and without evidence-based therapy. Here, we report the case of a 55-year-old woman with a germline mutation and a stage IV OCS who was proposed olaparib maintenance therapy after three platinum-based chemotherapies in relapsed disease. Currently, the patient has an overall survival of 102 months and progression-free survival of 60 months with olaparib, with a good quality of life and not experiencing any adverse events.

Real-life data on treatment and outcomes in advanced ovarian cancer: An observational, multinational cohort study (RESPONSE trial).

Background: This study aimed to describe the treatment strategies and outcomes for women with newly diagnosed advanced high-grade serous or endometrioid ovarian cancer (OC).

Methods: This observational study collected real-world medical record data from eight Western countries on the diagnostic workup, clinical outcomes, and treatment of adult women with newly diagnosed advanced (Stage III-IV) high-grade serous or endometrioid OC. Patients were selected backward in time from April 1, 2018 (the index date), with a target of 120 patients set per country, followed for ≥20 months.

Altered IgG glycosylation at COVID-19 diagnosis predicts disease severity.

The nature of the immune responses associated with COVID-19 pathogenesis and disease severity, as well as the breadth of vaccine coverage and duration of immunity, is still unclear. Given the unpredictability for developing a severe/complicated disease, there is an urgent need in the field for predictive biomarkers of COVID-19. We have analyzed IgG Fc N-glycan traits of 82 SARS-CoV-2+ unvaccinated patients, at diagnosis, by nano-LC-ESI-MS.

Impressive and durable clinical responses obtained with dabrafenib and trametinib in low-grade serous ovarian cancer harbouring a BRAF V600E mutation.

Low-grade serous ovarian cancer (LGSOC) is now considered a different entity from high-grade serous ovarian cancer. The chemoresistance inherent to this type of ovarian cancer narrows the therapeutic options, especially in the recurrent setting. It is thought that the mitogen-activated protein kinase (MAPK) pathway plays a significant role in the pathogenesis of these tumours, and about 2 to 20% of LGSOC harbour a BRAF mutation.

Multidisciplinary Approach to Multiple Multiresistant Agent Infection of Instrumented Spine Surgery: A Case Report.

Case: We report the case of a patient with consecutive infections with several multidrug-resistant agents-including carbapenem-resistant strains of Klebsiella pneumoniae among others-from a surgical wound infection after lumbar spine fusion, only successfully treated after the resort to novel antibiotics (ceftazidime-avibactam) in combination therapy.

Conclusions: Multidrug resistance has become a major challenge in today's medicine. Care should be taken to avoid their emergence, but when present, a multidisciplinary approach is mandatory to ensure clinically up-to-date treatment choices.
