Regional neuron loss following stroke can result in remote brain changes due to diaschisis and secondary brain atrophy. Whole brain changes post-stroke can be captured by the predicted brain age difference (brain-PAD), a neuroimaging-derived biomarker of global brain health previously associated with poorer chronic stroke outcomes. We hypothesized that greater lesion damage would be longitudinally associated with worsening brain-PAD during subacute stroke, and conversely, that poorer baseline brain-PAD would be associated with enlarged lesion damage.

Background: Despite consecutive decades of success in reducing malaria transmission, Ethiopia went off track towards its goal of malaria elimination by 2030, as outlined in the NMCP malaria strategy. Recent malaria outbreaks in Ethiopia are attributed to the emergence and spread of diagnostic and drug-resistant Plasmodium falciparum, increased insecticide resistance in major vectors and the spread of invasive Anopheles stephensi. The effects of the COVID-19 pandemic, environmental anomalies and internal conflicts have also potentially played a role in increasing malaria transmission.

To keep ahead of the evolution of resistance to insecticides in mosquitoes, national malaria control programmes must make use of a range of insecticides, both old and new, while monitoring resistance mechanisms. The outdoor-biting malaria vector Anopheles arabiensis is of increasing concern for malaria transmission because it is apparently less susceptible to many indoor control interventions, yet knowledge of its mechanisms of resistance remains limited. Furthermore, comparatively little is known in general about resistance to non-pyrethroid insecticides such as pirimiphos-methyl (PM), which are crucial for effective control in the context of globally high resistance to pyrethroids.

Background: Ethiopia faces several severe challenges in terms of malaria elimination, including drug resistance and diagnostic evasion in the Plasmodium falciparum parasite, insecticide resistance in the primary Anopheles malaria vector, and, most recently, the invasion of the Asian malaria vector Anopheles stephensi. Novel malaria control methods are therefore needed, and in this paper, we describe the evaluation of a larval source management (LSM) strategy implemented in response to An. stephensi.

Article Synopsis
  • * Researchers analyzed MRI scans from 501 stroke patients to assess regional brain-PAD and lesion loads, discovering that larger stroke lesions correlate with older brain-PAD in the affected areas and younger brain-PAD in the opposite hemisphere.
  • * The findings highlight that the severity of stroke damage is linked to poorer motor function, with machine learning models identifying specific brain regions and lesion characteristics as key predictors of motor outcomes.

Background: Parkinson disease (PD) is reported to be among the most prevalent neurodegenerative diseases globally, presenting ongoing challenges and increasing burden on health care systems. In an effort to support patients with PD, their carers, and the wider health care sector to manage this incurable condition, the focus has begun to shift away from traditional treatments. One of the most contemporary treatments includes prescribing assistive technologies (ATs), which are viewed as a way to promote independent living and deliver remote care.

Colorectal liver metastases (CRLM) can be surgically managed through open resections (OLR), laparoscopic resections (LLR), or robotic liver resections (RLR). However, there is ongoing uncertainty regarding the safety and effectiveness of minimally invasive approaches like LLR and RLR. This study aims to clarify these issues by conducting a network meta-analysis (NMA) to compare outcomes across OLR, LLR and RLR for patients with CRLM.

  • Ambulatory surgery centers are gaining popularity due to lower costs and better patient experiences, but this also brings challenges related to the complexity of cases and patient safety.
  • Anesthesiologists should take the lead in multidisciplinary teams to assess which patients and procedures are suitable for these centers, taking into account both physical and psychosocial factors.
  • Special attention is needed for pediatric patients, requiring trained staff and specific equipment, and overall facility capabilities, emergency preparedness, and staffing levels are vital for maintaining patient safety and staff morale.

Introduction: While extant research has looked at parole and its various actors as an institution, few studies recount the parole experience from the perspective of parolees. Additionally, despite the prevalence of substance use disorders (SUDs) within the criminal justice system, research that assesses the additional challenges this population faces throughout parole supervision is even scarcer.

Methods: To address this gap, we analyze in-depth qualitative interviews (n = 51) conducted with reentering men with SUDs as they navigate parole in Pennsylvania.

  • The Democratic Republic of Congo has a big problem with malaria, and it's important to know how mosquitoes that spread it are affected by insecticides, especially since they mainly use treated nets to fight the disease.
  • Scientists studied mosquitoes from three different areas in southern Congo and found that many of these mosquitoes are becoming resistant to the insecticides used on the nets, especially in the Kimpese area.
  • By looking at the genetic makeup of these mosquitoes, they discovered differences between some populations, suggesting that resistance is connected to certain genes, and a specific gene in Kimpese might be a key factor for understanding this resistance better.

Malaria control relies on insecticides targeting the mosquito vector, but this is increasingly compromised by insecticide resistance, which can be achieved by elevated expression of detoxifying enzymes that metabolize the insecticide. In diploid organisms, gene expression is regulated both in , by regulatory sequences on the same chromosome, and by acting factors, affecting both alleles equally. Differing levels of transcription can be caused by mutations in -regulatory modules (CRM), but few of these have been identified in mosquitoes.

Article Synopsis
  • Tororo District, Uganda saw a significant drop in malaria cases from 2015-2019 due to using indoor residual spraying (IRS) with different insecticides but experienced a surge in cases starting in 2020 after switching to a new insecticide formulation (Fludora Fusion/SumiShield).
  • From 2021 to 2022, malaria incidence and parasite prevalence dramatically increased when using Fludora Fusion, showing more than an 8-fold rise in incidence and over a 4-fold rise in parasite prevalence among local residents.
  • A subsequent return to using Actellic insecticide in 2023 led to a substantial decline in malaria cases and prevalence, with incidences dropping almost 5-fold and prevalence decreasing by

Conventional approaches for establishing bioequivalence (BE) between test and reference formulations using non-compartmental analysis (NCA) may demonstrate low power in pharmacokinetic (PK) studies with sparse sampling. In this case, model-integrated evidence (MIE) approaches for BE assessment have been shown to increase power, but may suffer from selection bias problems if models are built on the same data used for BE assessment. This work presents model averaging methods for BE evaluation and compares the power and type I error of these methods to conventional BE approaches for simulated studies of oral and ophthalmic formulations.

The major malaria mosquitoes, and , are some of the most studied organisms in medical research and also some of the most genetically diverse. When designing polymerase chain reaction (PCR) or hybridisation-based molecular assays, reliable primer and probe design is crucial. However, single nucleotide polymorphisms (SNPs) in primer binding sites can prevent primer binding, leading to null alleles, or bind suboptimally, leading to preferential amplification of specific alleles.
