This review is aimed at providing clinicians and public health staff with an updated and easy-to-consult document arising from consensus of Global Tuberculosis Network (GTN) experts. The core published documents and guidelines have been reviewed, including the recently published MDR-TB WHO rapid advice and ATS/CDC/ERS/IDSA guidelines.

Accuracy of component-resolved diagnostics in peanut allergy: Systematic literature review and meta-analysis.

Background: Peanut allergy diagnosis relies on clinical reactivity to peanut supported by detection of specific IgE (sIgE) antibodies. Extract-based sIgE tests have low specificity, so component-resolved diagnostics may complement whole-extract testing.

Methods: We systematically collected peanut allergen component data in seven databases and studied the diagnostic accuracy of peanut storage proteins (Arah1, 2, 3) and cross-reactive peanut proteins (Arah8 PR-10 and Arah9 lipid transfer protein) through meta-analyses.

Emerging non-13-valent pneumococcal conjugate vaccine (PCV13) serotypes causing adult invasive pneumococcal disease in the late-PCV13 period in Spain.

Objective: An early reduction of adult invasive pneumococcal disease (IPD) was observed after the 13-valent pneumococcal conjugate vaccine (PCV13) introduction for children in Spain. We analysed the epidemiology of adult IPD in the late-PCV13 period.

Methods: This was a prospective multicentre study of adult IPD involving six hospitals.

Hippocampal subfields revealed through unfolding and unsupervised clustering of laminar and morphological features in 3D BigBrain.

The internal structure of the human hippocampus is challenging to map using histology or neuroimaging due to its complex archicortical folding. Here, we aimed to overcome this challenge using a unique combination of three methods. First, we leveraged a histological dataset with unprecedented 3D coverage, BigBrain.

Preparation of dissociated mouse primary neuronal cultures from long-term cryopreserved brain tissue.

Background: Dissociated primary neuronal cultures are widely used as a model system to investigate the cellular and molecular properties of diverse neuronal populations and mechanisms of action potential generation and synaptic transmission. Typically, rodent primary neuronal cultures are obtained from freshly-dissociated embryonic or postnatal brain tissue, which often requires intense animal husbandry. This can strain resources when working with genetically modified mice.

Psychological distress in ethnic minority parents of preschool children with burns.

Background: Literature indicates that children from ethnic minorities are at increased risk of sustaining burns. Moreover, parents may experience more psychological distress but why this is the case is poorly investigated.

Methods: A prospective study including 120 mothers and 106 fathers of preschool children, of which 23 mothers and 24 fathers had an ethnic minority background, investigated levels of parental feelings of guilt, depressive and posttraumatic stress symptoms and compared Dutch parents with parents from different ethnic backgrounds on these outcomes.

AD biomarker discovery in CSF and in alternative matrices.

Core Alzheimer's Disease (AD) biomarkers are the cerebrospinal fluid (CSF) proteins amyloid β42 and β40, and the tau proteins, total and phosphorylated. Their use is recommended by research guidelines for diagnostic purpose and for stratification of patients for clinical trials. However, novel potential biomarkers are needed, which can mirror risk factors and other different mechanisms of the disease, hopefully in less invasive biological fluids or matrices.

Archival, paleopathological and aDNA-based techniques in leprosy research and the case of Father Petrus Donders at the Leprosarium 'Batavia', Suriname.

Objective: We assessed whether Petrus Donders (died 1887), a Dutch priest who for 27 years cared for people with leprosy in the leprosarium Batavia, Suriname, had evidence of Mycobacterium (M.) leprae infection. A positive finding of M.

Action boosts episodic memory encoding in humans via engagement of a noradrenergic system.

We are constantly interacting with our environment whilst we encode memories. However, how actions influence memory formation remains poorly understood. Goal-directed movement engages the locus coeruleus (LC), the main source of noradrenaline in the brain.

Real-world efficacy and safety of lenvatinib: data from a compassionate use in the treatment of radioactive iodine-refractory differentiated thyroid cancer patients in Italy.

Background: Lenvatinib is a multi-kinase inhibitor approved for patients with radioactive iodine (RAI)-resistant differentiated thyroid cancer (DTC). Before the drug approval from the Italian National Regulatory Agency, a compassionate use programme has been run in Italy. This retrospective study aimed to analyse data from the first series of patients treated with lenvatinib in Italy.

Current perspectives on established and novel therapies for pathological neovascularization in retinal disease.

Neovascularization is a hallmark pathology of numerous retinal diseases from diabetic retinopathy (DR) to age-related related macular degeneration (AMD). Over the past 2 decades, the rise of anti-VEGF based medications for neovascular eye conditions has revolutionized the treatment paradigm for patients and preserved the vision of millions. With any form of therapy however, there remain pitfalls and areas for improved interventions.

Surveillance of adverse events in the treatment of drug-resistant tuberculosis: A global feasibility study.

The World Health Organization launched a global initiative, known as aDSM (active TB drug safety monitoring and management) to better describe the safety profile of new treatment regimens for drug-resistant tuberculosis (TB) in real-world settings. However, comprehensive surveillance is difficult to implement in several countries. The aim of the aDSM project is to demonstrate the feasibility of implementing national aDSM registers and to describe the type and the frequency of adverse events (AEs) associated with exposure to the new anti-TB drugs.

Defective exocytosis and processing of insulin in a cystic fibrosis mouse model.

Cystic fibrosis-related diabetes (CFRD) is a common complication for patients with cystic fibrosis (CF), a disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR). The cause of CFRD is unclear, but a commonly observed reduction in first-phase insulin secretion suggests defects at the beta cell level. Here we aimed to examine beta- and alpha-cell function in the Cftrtm1EUR/F508del mouse model (C57BL/6J), which carries the most common human mutation in CFTR, the F508del mutation.

Detection of West Nile virus lineage 1 sequences in blood donors, Punjab Province, Pakistan.

Objectives: This study was performed to determine the presence of West Nile virus (WNV) in mosquito specimens and human blood donors in Pakistan.

Methods: A total of 4150 mosquito specimens were collected using CO-baited traps from five selected districts of Punjab Province, Pakistan. The mosquitoes were taxonomically identified using standard morphological keys, resulting in 166 pools.

Workload measurement for molecular genetics laboratory: A survey study.

Genetic testing availability in the health care system is rapidly increasing, along with the diffusion of next-generation sequencing (NGS) into diagnostics. These issues make imperative the knowledge-drive optimization of testing in the clinical setting. Time estimations of wet laboratory procedure in Italian molecular laboratories offering genetic diagnosis were evaluated to provide data suitable to adjust efficiency and optimize health policies and costs.

An international perspective on hospitalized patients with viral community-acquired pneumonia.

Background: Who should be tested for viruses in patients with community acquired pneumonia (CAP), prevalence and risk factors for viral CAP are still debated. We evaluated the frequency of viral testing, virus prevalence, risk factors and treatment coverage with oseltamivir in patients admitted for CAP.

Methods: Secondary analysis of GLIMP, an international, multicenter, point-prevalence study of hospitalized adults with CAP.

Effects of electrode angle-orientation on the impact of transcranial direct current stimulation on motor cortex excitability.

Background: For effects of transcranial direct current stimulation (tDCS), electrical field distribution and coverage of the target areas play a decisive role.

Methods: We explored the effect of different angle-orientations of tDCS electrodes applied over the upper limb motor cortex (M1) on motor cortex excitability in healthy volunteers. Sixteen individuals received 1 mA anodal or cathodal tDCS through 35 cm electrodes over M1 for 15 min.

Novelty exposure hinders aversive memory generalization and depends on hippocampal protein synthesis.

Fear generalization is defined as the transferring of fear experienced during a traumatic event to safe conditions resembling or not the traumatic event. It has been related to several psychological disorders. Here we set out to determine whether novelty exposure can be effective to avoid fear generalization.

Thyroid ultrasonography reporting: consensus of Italian Thyroid Association (AIT), Italian Society of Endocrinology (SIE), Italian Society of Ultrasonography in Medicine and Biology (SIUMB) and Ultrasound Chapter of Italian Society of Medical Radiology (SIRM).

Thyroid ultrasonography (US) is the gold standard for thyroid imaging and its widespread use is due to an optimal spatial resolution for superficial anatomic structures, a low cost and the lack of health risks. Thyroid US is a pivotal tool for the diagnosis and follow-up of autoimmune thyroid diseases, for assessing nodule size and echostructure and defining the risk of malignancy in thyroid nodules. The main limitation of US is the poor reproducibility, due to the variable experience of the operators and the different performance and settings of the equipments.

Functional movement disorders of the face: A historical review and case series.

Functional facial dystonia or spasm has, in recent years, been recognised as a relatively common form of functional movement disorder. We describe historical 'forgotten' neurological literature indicating that this was a well described phenomenon in the late 19th and early 20th century but subsequently faded from awareness. We add data from our own series of 41 patients with functional facial dystonia to explore the clinical features and associated comorbidities of patients with this movement disorder.
