Article Synopsis
  • * Researchers trained deep learning models using over 152,000 chest X-rays from applicants aged 15 and older to identify abnormalities, specifically those related to TB, and to classify findings like cavities or infiltrates.
  • * The models demonstrated high accuracy, with an area under the curve (AUC) score of up to 0.99 for detecting TB-related abnormalities and performed well across various testing datasets, indicating reliability in this diagnostic method.

US-bound immigrants and refugees undergo a mandatory overseas medical examination that includes tuberculosis screening; this exam is not routinely required for temporary visitors applying for non-immigrant visas (NIV) to visit, work, or study in the United States. US health departments and foreign ministries of health report tuberculosis cases in travelers to Centers for Disease Control and Prevention Quarantine Stations. We reviewed cases reported to this passive surveillance system from January 2011 to June 2016.

In March 2021, Emergency Intake Sites (EIS) were created to address capacity shortfalls during a surge of Unaccompanied Children at the Mexico-United States land border. The COVID-19 Zone Plan (ZP) was developed to decrease COVID-19 transmission. COVID-19 cumulative percent (%) positivity was analyzed to evaluate the impact of the ZP, venue type and bed capacity across EIS from April 1-May 31, 2021.

This study was a 10-week double-blind, placebo-controlled pilot trial of mirtazapine for anxiety in youth with autism spectrum disorder (ASD). Participants were ages 5 to 17 years with ASD and clinically significant anxiety (Pediatric Anxiety Rating Scale [PARS] score ≥10). Thirty participants were randomized to mirtazapine (7.

Objective: To assess outcomes from the US postarrival evaluation of newly arrived immigrant and refugee children aged 2-14 years who were diagnosed with latent tuberculosis infection (LTBI) during a required overseas medical examination.

Study Design: We compared overseas and US interferon-γ release assay (IGRA)/tuberculin skin test (TST) results and LTBI diagnosis; assessed postarrival LTBI treatment initiation and completion; and evaluated the impact of switching from TST to IGRA to detect Mycobacterium tuberculosis infection overseas.

Results: In total, 73 014 children were diagnosed with LTBI overseas and arrived in the US during 2007-2019.

Problem/condition: Each year, approximately 500,000 immigrants and tens of thousands of refugees (range: 12,000-85,000 during 2001-2020) move to the United States. While still abroad, immigrants, refugees, and others who apply for admission to live permanently in the United States must undergo a medical examination. This examination identifies persons with class A or B conditions.

We assessed the overseas gonorrhea results reported in the CDC's Electronic Disease Notification (EDN) system among refugees ≥ 15 years old who arrived in the United States during 2018. Of 18,720 refugees, 57 (0.4%) tested positive.

Background: While persons who receive immigrant and refugee visas are screened for active tuberculosis before admission into the United States, nonimmigrant visa applicants (NIVs) are not routinely screened and may enter the United States with infectious tuberculosis.

Objectives: We evaluated the costs and benefits of expanding pre-departure tuberculosis screening requirements to a subset of NIVs who arrive from a moderate (Mexico) or high (India) incidence tuberculosis country with temporary work visas.

Methods: We developed a decision tree model to evaluate the program costs and estimate the numbers of active tuberculosis cases that may be diagnosed in the United States in two scenarios: 1) "Screening": screening and treatment for tuberculosis among NIVs in their home country with recommended U.

Background: Tuberculosis (TB) Regional Training and Medical Consultation Centers (RTMCCs) were established in 2005 for TB medical consultation, training and education in the United States. A medical consultation database (MCD) captured all consultations provided by RTMCCs; we report on those provided from June 1, 2010 to May 31, 2014.

Methods: All MCD consultations during 2010-2014 were categorized into: provider type, setting, consultation topic, and patient age.

Migration and forced displacement are at record levels in today's geopolitical environment; ensuring the health of migrating populations and the health security of asylum and receiving countries is critically important. Overseas screening, treatment, and vaccination during planned migration to the United States represents one successful model. These strategies have improved tuberculosis detection and treatment, reducing rates in the United States; decreased transmission and importation of vaccine-preventable diseases; prevented morbidity and mortality from parasitic diseases among refugees; and saved health costs.

The association between chronic kidney disease (CKD) and tuberculosis disease (TB) has been recognized for decades. Recently CKD prevalence is increasing in low- to middle-income countries with high TB burden. Using data from the required overseas medical exam and the recommended US follow-up exam for 444,356 US-bound refugees aged ≥ 18 during 2009-2017, we ran Poisson regression to assess the prevalence of TB among refugees with and without CKD, controlling for sex, age, diabetes, tobacco use, body mass index ( kg/m), prior residence in camp or non-camp setting, and region of birth country.

The intracellular environment is a dynamic space filled with various organelles moving in all directions. Included in this diverse group of organelles are vesicles, which are involved in transport of molecular cargo throughout the cell. Vesicles move in either a directed or non-directed fashion, often depending on interactions with cytoskeletal proteins such as microtubules, actin filaments, and molecular motors.

Background: Pillar 3 of the End TB Strategy calls for the promotion of research and innovation at the country level to facilitate improved implementation of existing and novel interventions to end tuberculosis (TB). In an era of increasing cross-border migration, there is a specific need to integrate migration-related issues into national TB research agendas. The objective of the present review is to provide a conceptual framework to guide countries in the development and operationalization of a migrant-inclusive TB research agenda.

Setting: In 2007, the US Centers for Disease Control and Prevention (CDC) revised its tuberculosis (TB) technical instructions for panel physicians who administer mandatory medical examinations among US-bound immigrants. Many US-bound immigrants come from the Philippines, a high TB prevalence country.

Effective tuberculosis (TB) prevention and care for migrants requires population health-based approaches that treat the relationship between migration and health as a progressive, interactive process influenced by many variables and addressed as far upstream in the process as possible. By including capacity building in source countries, pre-migration medical screening has the potential to become an integral component of public health promotion, as well as infection and disease prevention, in migrant-receiving nations, while simultaneously increasing capabilities in countries of origin. This article describes the collaborative experiences of five countries (Australia, Canada, New Zealand, United Kingdom and the United States of America, members of the Immigration and Refugee Health Working Group [IRHWG]), with similar pre-migration screening programmes for TB that are mandated.

. Tuberculosis control in foreign-born populations is a major public health concern for Australia, Canada, New Zealand, United Kingdom, and the United States, large immigrant- and refugee-receiving countries that comprise the Immigration and Refugee Health Working Group (IRHWG). Identifying and comparing immigration and distribution of foreign-born tuberculosis cases are important for developing targeted and collaborative interventions.

Background: d-Cycloserine (DCS) enhances extinction learning across species, but it has proven challenging to identify consistent benefit of DCS when added to therapeutic interventions. We conducted a placebo-controlled trial of DCS to potentiate social skills training in autism spectrum disorder (ASD) but found substantial improvement in both the DCS and placebo groups at the conclusion of active treatment. Here, we assess the impact of DCS 11 weeks following active treatment to evaluate the impact of DCS on treatment response durability.
