Transformer based models for time-series forecasting have shown promising performance and during the past few years different Transformer variants have been proposed in time-series forecasting domain. However, most of the existing methods, mainly represent the time-series from a single scale, making it challenging to capture various time granularities or ignore inter-series correlations between the series which might lead to inaccurate forecasts. In this paper, we address the above mentioned shortcomings and propose a Transformer based model which integrates multi-scale patch-wise temporal modeling and channel-wise representation.

Background: The Bari-SolidAct randomized controlled trial compared baricitinib with placebo in patients with severe COVID-19. A post hoc analysis revealed a higher incidence of serious adverse events (SAEs) among SARS-CoV-2-vaccinated participants who had received baricitinib. This sub-study aimed to investigate whether vaccination influences the safety profile of baricitinib in patients with severe COVID-19.

Rinderpest and peste des petits ruminants (PPR) are two closely related viral diseases caused by viruses belonging to the genus Morbillivirus and affecting ruminants. Both diseases are notifiable to the World Organisation for Animal Health (WOAH) due to their high contagiosity and economic importance. International collaboration and scientific developments have led to the eradication of rinderpest, which was celebrated in 2011, 250 years after the first veterinary school was created in Lyon.

Background: At the beginning of the 2018-2020 outbreak of Ebola virus disease (EVD) in eastern Democratic Republic of Congo (DRC), no vaccine had been licensed. However, cluster-randomized evidence from Guinea in 2015 had indicated that ring vaccination around new cases (targeting contacts and contacts-of-contacts) with the use of single-dose live-replicating rVSV-ZEBOV-GP vaccine reduced EVD rates starting 10 days after vaccination. Thus, ring vaccination was added to the standard control measures for that outbreak.

Prescription Produce Programs (PPPs) are increasingly being used to address food insecurity and healthy diets. Yet, limited evidence exists on the effectiveness of integrating lifestyle counseling within a PPP to promote dietary and health behaviors. To describe the implementation of a 6- or 12-week PPP integrating lifestyle counseling to low-income adults.

Article Synopsis
  • Sickle cell emergencies are a leading reason for hospitalizations in patients with sickle cell disease, causing significant financial strain and increased health risks.
  • A study tracked 112 adults with sickle cell emergencies over four months, revealing a 38.41% readmission rate within 30 days, predominantly due to vaso-occlusive crises and acute chest syndrome.
  • Key factors predicting readmission included having a job, low levels of fetal hemoglobin, and certain blood cell counts (neutrophilia, lymphocytosis, thrombocytosis).

In sub-Saharan Africa, children with severe malnutrition (SM) and HIV have substantially worse outcomes than children with SM alone, facing higher mortality risk and impaired nutritional recovery post-hospitalisation. Biological mechanisms underpinning this risk remain incompletely understood. This case-control study nested within the CHAIN cohort in Kenya, Uganda, Malawi, and Burkina Faso examined effect of HIV on six months post-discharge growth among children with SM and those at risk of malnutrition, assessed proteomic signatures associated with HIV in these children, and investigated how these systemic processes impact post-discharge growth in children with SM.

Spinal motor neuron (MN) dysfunction is the cause of a number of clinically significant movement disorders. Despite the recent approval of gene therapeutics targeting these MN-related disorders, there are no viral delivery mechanisms that achieve MN-restricted transgene expression. In this study, chromatin accessibility profiling of genetically defined mouse MNs was used to identify candidate cis-regulatory elements (CREs) capable of driving MN-selective gene expression.

Article Synopsis
  • The Great Green Wall initiative's restoration efforts in the northern Sahel focus primarily on plants and often overlook key plant-animal interactions crucial for ecosystem health, particularly those involving flower-visiting insects.
  • Research indicates that many insects, especially bees, rely heavily on diverse floral resources for pollination, which is vital for maintaining biodiversity and ecological sustainability in the region, despite the challenges posed by extensive pastoralism.
  • The study emphasizes the need for more research on insect-flower interactions to fill knowledge gaps and enhance the effectiveness of restoration strategies, highlighting the importance of trees and floral visitors in sustaining food webs and ecosystem resilience.

Article Synopsis
  • Peste des Petits Ruminants (PPR) is a disease common in Africa, and effective live attenuated vaccines (Nigeria 75/1 and Sungri/96 strains) are produced to combat it, but maintaining the cold chain for these vaccines is challenging.
  • The study assessed the thermotolerance of various stabilizer formulations for freeze-dried and reconstituted PPR vaccines by testing their viability at different temperatures over time.
  • Results indicated that the formulation with lactalbumin hydrolysate-sucrose showed the best stability, maintaining vaccine efficacy at higher temperatures, suggesting it should be the preferred stabilizer for vaccines distributed in warmer climates.

Over the past century, human lifespan has increased remarkably, yet the inevitability of aging persists. The disparity between biological age, which reflects pathological deterioration and disease, and chronological age, indicative of normal aging, has driven prior research focused on identifying mechanisms that could inform interventions to reverse excessive age-related deterioration and reduce morbidity and mortality. DNA methylation has emerged as an important predictor of age, leading to the development of epigenetic clocks that quantify the extent of pathological deterioration beyond what is typically expected for a given age.

  • The study aimed to analyze how paracetamol and its metabolites behave in extremely preterm neonates during treatment for patent ductus arteriosus and to identify factors influencing variability in individual responses.
  • Thirty preterm neonates receiving paracetamol were monitored, revealing that the drug was mostly metabolized through the sulfation pathway, which decreased with gestational age, while the glucuronidation pathway increased.
  • The results showed no link between the level of drug exposure and clinical outcomes or liver function indicators, suggesting that the dosages used might already achieve optimal effectiveness for ductus closure.

Chlamydia trachomatis infections are the most common bacterial STIs globally and can lead to serious morbidity if untreated. Development of a killed, whole-cell vaccine has been stymied by coincident epitope destruction during inactivation. Here, we present a prototype Chlamydia vaccine composed of elementary bodies (EBs) from the related mouse pathogen, Chlamydia muridarum (Cm).

This study presents four different impeller designs to compare hydrodynamic forces. Numerical simulation studies are performed via computational fluid dynamics to specify and investigate the hydraulic forces impacting the impeller of the mixed-flow blood pump with a volute. The design point of this pump is that the flow rate is 5 L/min, the rotational speed is 8000 rpm, and the manometric head is 100 mmHg.

Article Synopsis
  • The study investigated the effectiveness and safety of the rVSV-ZEBOV vaccine against Zaire Ebolavirus disease among contacts of EVD survivors, focusing on the influence of pre-existing immunity on vaccination outcomes.
  • Ten percent of participants had pre-existing antibodies, but both those with and without antibodies showed significant increases in IgG levels post-vaccination, indicating strong immune responses.
  • The findings support the vaccine's safety and suggest that pre-vaccination antibody screening is unnecessary, as it does not negatively impact the immune response to the vaccine.
