Objective: This report examines telemedicine use by office-based physicians and long-term care providers in the United States, stratified by electronic health record use and by provider or practice size. Further, it examines differences in telemedicine use before and after the COVID-19 pandemic onset among office-based physicians and assesses telemedicine use during the first year of the COVID-19 pandemic for long-term care providers.

Methods: Nationally representative estimates in this report are derived from data collected in the 2019 and 2021 National Electronic Health Records Survey, which assesses characteristics of office-based physicians, and the 2020 National Post-acute and Long-term Care Study, which assesses characteristics of adult day services centers and residential care communities.

Introduction: Countries use the WHO Joint External Evaluation (JEE) tool-part of the WHO International Health Regulations (2005) Monitoring and Evaluation Framework-for voluntary evaluation of global health security (GHS) capacities. After releasing the JEE first edition (E1) in 2016, WHO released the JEE second edition (E2) in 2018 with language changes to multiple indicators and associated capacity levels. To understand the effect of language changes on countries' ability to meet requirements in each edition, we conducted a Delphi study-a method where a panel of experts reach consensus on a topic through iterative, anonymous surveys-to solicit feedback from 40+ GHS experts with expertise in one or more of the 19 JEE technical areas.

Background: Although physicians are highly regarded members of society, patients are not always satisfied with their care, suggesting a mismatch between the public's expectations and reality. Thus, the aim of this study was to determine the public's expectations regarding roles and responsibilities of a physician, to assess patient experiences, and to evaluate factors associated with the two outcomes.

Methods: A cross-sectional study was conducted via face-to-face structured interviews from July 14th to August 2nd, 2023, in Karachi, Pakistan.

Article Synopsis
  • * Through advanced imaging techniques, researchers assessed the relationship between the vascular structure of the tumors and the treatment response, revealing that tumors responding to the drug had a more balanced blood vessel composition compared to resistant ones.
  • * The findings suggest that understanding the vascular architecture could enhance our knowledge of how immune therapies work in the brain, potentially guiding future treatment strategies.

Background: All countries are required to implement International Health Regulations (IHR) through development and implementation of multi-year National Action Plans for Health Security (NAPHS). IHR implementation requires annual operational planning which involves several tools such as NAPHS, State Party Annual Report (SPAR), Joint External Evaluation (JEE) and WHO IHR Benchmarks tool. Sierra Leone has successfully improved IHR capacities across the years through successful annual operational planning using the above tools.

Article Synopsis
  • Tumor angiogenesis often leads to abnormal blood vessel development, which is linked to treatment resistance and immune suppression in cancers, specifically brain metastases.
  • A study using perfusion MRI on 44 patients treated with the immune checkpoint inhibitor pembrolizumab revealed that responsive tumors had balanced vascular structures, promoting better blood flow and a supportive immune environment.
  • In contrast, resistant tumors exhibited chaotic blood vessels and low immune cell presence, with early functional changes detectable through MRI that indicated resistance before conventional imaging could.

Article Synopsis
  • Brain metastases (BMs) are increasingly common in cancer patients, and the study evaluates the effectiveness of pembrolizumab, an immunotherapy drug, in treating 57 patients with untreated and recurrent BMs.
  • The trial found that 42.1% of patients experienced an intracranial benefit, with a median overall survival of 8 months, and a portion of patients (12.3%) survived over 2 years.
  • However, over half of the subjects reported serious side effects, indicating a need for more research to understand which patients might respond best to this treatment and why some experience resistance.

Objectives: To characterize demographics, birth parameters, and social determinants of health among mother-infant dyads affected by neonatal abstinence syndrome (NAS) in Pennsylvania.

Methods: We linked 2018-2019 NAS surveillance data to birth record data using probabilistic methods and then geospatially linked to local social determinants of health data based on residential address. We generated descriptive statistics and used multivariable mixed-effects logistic regression to model the association between maternal characteristics, birth parameters, social determinants of health, and NAS.

Introduction: Maximizing patients' quality of life (QoL) is a central goal in surgical oncology. Currently, both laparoscopic and robotic surgery are viable options in rectal cancer (RC) resections. The aim of this systematic review was to analyze the differences in postoperative QoL between the two operative modalities.

Nickel-supported hierarchical zeolite catalysts were prepared through a desilication reassembly process under optimized conditions and applied in one-pot menthol synthesis. In this work, the hierarchical zeolite-supported metal bifunctional catalysts were prepared with the help of desilication re-assembly and wetness impregnation techniques and applied in menthol synthesis via citral hydrogenation. The prepared catalysts were characterized using PXRD, BET, FE-TEM, NH-TPD, H-TPR, pyridine adsorption, and ICP-OES techniques.

  • Daprodustat is a new treatment for anemia in chronic kidney disease (CKD) patients, showing similar effectiveness to the traditional treatment, recombinant human erythropoietin (rhEPO), in increasing hemoglobin levels.
  • In a study involving over 8,000 CKD patients, daprodustat significantly reduced major adverse cardiovascular events compared to rhEPO, particularly in patients with dialysis-dependent CKD (DD-CKD).
  • While daprodustat and rhEPO both affect iron metabolism, their effects vary, with daprodustat exhibiting advantages in some areas and disadvantages in others.

Adopting density functional theory (DFT) technique, the spintronic and opto-electronic characteristics of MnO (, Mn, MnO, MnO, MnO and MnO) clusters intercalated bilayer AlN (BL/AlN) systems are investigated in this paper. In terms of electron transfer, charge transfer occurs from BL/AlN to the MnO clusters. MnO clusters intercalation induces magnetic behavior in the non-magnetic AlN system.

Article Synopsis
  • Leptomeningeal disease (LMD) is a severe cancer complication often missed due to the low accuracy of current diagnostic methods like CSF cytology.
  • This study aimed to evaluate if analyzing cell-free DNA (cfDNA) in CSF could provide a more reliable diagnosis for LMD compared to traditional cytologic methods.
  • In a cohort of 30 patients, cfDNA analysis identified LMD correctly in 94% of follow-up samples, significantly outperforming cytologic analysis, indicating a potential improvement in diagnosing LMD.

Noncommunicable diseases and their risk factors are important for all aspects of outbreak preparedness and response, affecting a range of factors including host susceptibility, pathogen virulence, and health system capacity. This conceptual analysis has 2 objectives. First, we use the Haddon matrix paradigm to formulate a framework for assessing the relevance of noncommunicable diseases to health security efforts throughout all phases of the disaster life cycle: before, during, and after an event.

Differentiated cells can re-enter the cell cycle to repair tissue damage via a series of discrete morphological and molecular stages coordinated by the cellular energetics regulator mTORC1. We previously proposed the term "paligenosis" to describe this conserved cellular regeneration program. Here, we detail a molecular network regulating mTORC1 during paligenosis in both mouse pancreatic acinar and gastric chief cells.
