Psychological interventions are complex in nature and have been shown to benefit various clinical outcomes. Gaining insight into current practices would help identify specific aspects that need improvement to enhance the quality of network meta-analysis (NMA) in this field. This scoping review aimed to explore methodological approaches in the NMA of psychological interventions.

Background: Acute respiratory infections are a common reason for consultation with primary and emergency healthcare services. Identifying individuals with a bacterial infection is crucial to ensure appropriate treatment. However, it is also important to avoid overprescription of antibiotics, to prevent unnecessary side effects and antimicrobial resistance.

Background: Beta-blocker prescriptions for patients with anxiety increased substantially between 2003 and 2018, yet there is no clinical guidance concerning their use. A previous review of propranolol - a beta-blocker - in the treatment of anxiety concluded there was insufficient evidence to support its use. Additional data have been published in the eight years since that review including some evidence for other beta-blockers.

Background: Various effective treatments for depression exist. We aimed to identify the most effective first-line treatments for new episodes of less and more severe depression (defined by depression scale cut-off scores), to update NICE guidance on the management of Depression in Adults in England.

Methods: Systematic review and network meta-analysis of randomised controlled trials (RCTs) published up to June 2020 (PROSPERO registration number CRD42019151328).

Background: Diffusion tensor imaging (DTI) can characterize eloquent white matter tracts affected by brain arteriovenous malformations (AVMs). However, DTI interpretation can be difficult in ruptured cases due to the presence of blood products. The authors present the case of a ruptured pediatric AVM in the corticospinal tract (CST) and discuss how DTI at different time points informed the treatment.

The research community has conducted several controlled "in -lab" assessments on the effectiveness of industrial exoskeletons, paving the way for their adoption. However, field testing, focusing on ergonomics and the user experience, could serve to enhance both end-users' awareness and address open doubts concerning true effectiveness of industrial exoskeletons. This study presents an analysis of qualitative data regarding the use of back-support exoskeletons during field trials in harsh civil engineering environments.

Giant exoplanets orbiting close to their host stars are unlikely to have formed in their present configurations. These 'hot Jupiter' planets are instead thought to have migrated inward from beyond the ice line and several viable migration channels have been proposed, including eccentricity excitation through angular-momentum exchange with a third body followed by tidally driven orbital circularization. The discovery of the extremely eccentric (e = 0.

Background: Postoperative hyponatremia is a known complication of intracranial surgery, which can present with depressed mental status. Hyponatremia resulting in focal neurologic deficits is less frequently described.

Case Description: We describe a patient who, after a bifrontal craniotomy for olfactory groove meningioma, developed acute hyponatremia overnight with a decline in mental status from Glasgow coma scale (GCS) score 15 to GCS 7 and a unilateral fixed dilated pupil.

Commonly used risk indexes, such as the NIOSH Lifting Index, do not capture the effect of exoskeletons. This makes it difficult for Health and Safety professionals to rigorously assess the benefit of such devices. The community requires a simple method to assess the effectiveness of back-support exoskeleton's (BSE) in possibly reducing ergonomic risk.

Youth experiencing homelessness (YEH) are infrequently included in the development, organization, and provision of homelessness-related services. This lack of youth voice and services tailored for their expressed needs can lead to underutilization of services, dissatisfaction, and poor outcomes. Photovoice, a participatory research method, has been used to empower persons from marginalized populations and to provide a platform for them to share their voices.

Invariant natural killer T (iNKT) cells play an important role in many innate and adaptive immune responses, with potential applications in cancer immunotherapy. The glycolipid KRN7000, an α-galactosylceramide, potently activates iNKT cells but has shown limited anticancer effects in human clinical trials conducted so far. In spite of almost three decades of structure-activity relationship studies, no alternative glycolipid has yet emerged as a superior clinical candidate.

Background: Adolescent multiple risk behaviour (MRB) is a global health issue. Most interventions have focused on the proximal causes of adolescent MRB such as peer or family influence, with systematic reviews reporting mixed evidence of effectiveness. There is increasing recognition that community mobilisation approaches could be beneficial for adolescent health.

This study on occupational back-support exoskeletons performs a laboratory evaluation of realistic tasks with expert workers from the railway sector. Workers performed both a static task and a dynamic task, each involving manual material handling (MMH) and manipulating loads of 20 kg, in three conditions: without an exoskeleton, with a commercially available passive exoskeleton (Laevo v2.56), and with the StreamEXO, an active back-support exoskeleton developed by our institute.

Objective: The purpose of this study is to use feedback from student evaluations of teaching (SETs) to define and describe themes associated with perceived teaching effectiveness.

Methods: We retrospectively analyzed SETs for instructors in required didactic courses from one academic year using qualitative content analysis. The analysis included student responses to the following questions: "Describe the strongest aspect of the instructor's teaching.

Work-related musculoskeletal disorders are globally one of the leading causes of work-related injuries. They significantly impact worker health and business costs. Work task ergonomic risk indices have been developed that use observational assessments to identify potential injuries, and allow safety managers to promptly intervene to mitigate the risks.

Network meta-analysis (NMA) is an extension of pairwise meta-analysis (PMA) which combines evidence from trials on multiple treatments in connected networks. NMA delivers internally consistent estimates of relative treatment efficacy, needed for rational decision making. Over its first 20 years NMA's use has grown exponentially, with applications in both health technology assessment (HTA), primarily re-imbursement decisions and clinical guideline development, and clinical research publications.

Bioluminescence imaging enables the sensitive tracking of cell populations and the visualization of biological processes in living systems. Bioluminescent luciferase/luciferin pairs with far-red and near-infrared emission benefit from the reduced competitive absorption by blood and tissue while also facilitating multiplexing strategies. Luciferins with extended π-systems, such as AkaLumine and recently reported CouLuc-1 and -3, can be used for bioluminescence imaging in this long wavelength regime.

Tar spot, a disease caused by the ascomycete fungal pathogen , is considered one of the most significant yield-limiting diseases of maize () within the United States. may also be found in association with other fungi, forming a disease complex that is thought to result in the characteristic fisheye lesions. Understanding how colonizes maize leaf cells is essential for developing effective disease control strategies.

Background: A panic attack is a discrete period of fear or anxiety that has a rapid onset and reaches a peak within 10 minutes. The main symptoms involve bodily systems, such as racing heart, chest pain, sweating, shaking, dizziness, flushing, churning stomach, faintness and breathlessness. Other recognised panic attack symptoms involve fearful cognitions, such as the fear of collapse, going mad or dying, and derealisation (the sensation that the world is unreal).

Back-support exoskeletons are commonly used in the workplace to reduce low back pain risk for workers performing demanding activities. However, for the assistance of tasks differing from lifting, back-support exoskeletons potential has not been exploited extensively. This work focuses on the use of an active back-support exoskeleton to assist carrying.
