[Cutaneous microbiologic profiles of Japanese adults residing in the United States of America].

Quantitative cutaneous bacteriological profile analysis was performed on 20 healthy Japanese adults. Five ecologically different sites were cultured, the forehead, anterior nares, axilla, perineum, and fourth interspace. Antibiotic sensitivity patterns were determined for the various species of coagulase negative cocci (CNS). Aerobic organisms were found in densities exceeding 10(6) per sample for all sites except the forehead (10(4)), while anaerobic Propionibacteria were found in quantities ranging from 10(5) to 10(6) per sample except for the toe web space, which was devoid of anaerobic org

[Progress in the study, treatment and cure of hematologic malignancies in children in North America].

Progress in the study, treatment and cure of hematologic malignancies in children is one of the most gratifying accounts in the entire history of cancer therapy. It is important to note that progress in treatment and cure have been the direct result of formal study of childhood cancers and the development and clinical trial of new treatments designed to improve the response and cure rate. In the experience of the Children's Cancer Study Group (CCSG), approximately half of the children with cancer which are registered have hematologic malignancies. By far the most significant of these is acute

The emergence of Lyme disease in a changing environment in North America and central Europe.

Lyme disease has recently begun to emerge as a significant threat to human health, both in Europe and the United States. Late sequellae, resembling those of neurosyphilis and multiple sclerosis, may occur many years after initial infection. Spontaneous abortion accompanies arthritis, carditis and neuritis as burdensome short-term sequellae. Thousands of new infections are recognized each year on each side of the Atlantic, although reporting may be incomplete. The disease was described in Europe nearly a century ago and named erythema chronicum migrans, but its etiology has only recently been d

The first case of congenital/connatal malaria from Guyana, South America.

The first case of congenital/connatal malaria from Guyana, South America was discovered in the capital city of Georgetown. The infection of the mother was acquired during a visit to the North West, an area of exclusive vivax malaria and of increasing endemicity.

Mapping country-level structural capacity constraints in brachytherapy infrastructure for locally advanced cervical cancer in the Americas: a cross-sectional study.

OBJECTIVE: To develop a reproducible public-data method for mapping country-level capacity constraints in brachytherapy infrastructure relevant to guideline-concordant treatment for locally advanced cervical cancer across the Americas, comparing expected disease-stage-specific need with reported brachytherapy unit counts. METHODS: We performed a cross-sectional ecological study at the country/territory level. Incident cervical cancer cases among females in 2022 were taken from GLOBOCAN-derived extracts and were linked with radiotherapy infrastructure data from the International Atomic Energy …

Comparing the Risk of SARS-CoV-2 Immune Resistance Evolving Across Regions in the Americas with Differing Approaches to Public Health.

Public health policy foundationally impacts how pathogens spread, yet despite multiple pathogens of broader societal concern emerging, little research has examined how policy affects pathogen evolution. To evaluate this connection, we examine how varying public health approaches impact how viral immune susceptibility, including resistance to vaccines, evolves. Integrating evolutionary epidemiological modeling and critical geography, we compare how distinct public health responses early in the COVID-19 pandemic affected the potential evolution of immune evasion in SARS-CoV-2 across four territo

Stroke Burden Attributable to Risk Factors in the Americas, 1990 to 2021: A Temporal Trends Analysis From the GBD Study 2021.

BACKGROUND: Stroke burden varies across the Americas, yet data on modifiable risk factor contributions remain limited. METHODS: Using GBD (Global Burden of Disease) study 2021 data, we analyzed stroke mortality and disability-adjusted life-year (DALY) rates attributable to 23 modifiable risk factors across 39 countries and territories in the Americas. Age-standardized rates were compared by sex, stroke subtype, region, and Socio-Demographic Index; age-specific estimates used 5-year groups (25-95+ years). Trends were assessed using average annual percentage change (AAPC) from Joinpoint regress…

Аналитическая и клиническая оценка группы СТАНДАРД M10 Arbovirus для обнаружения, серотипирования и многоразового скрининга в Северной и Южной Америке.

Фон/цели: Арбовирусы, включая вирус денге (DENV), вирус Зика (ZIKV), вирус Чикунгуньи (CHIKV), вирус желтой лихорадки (YFV) и вирус Западного Нила (WNV), совместно циркулируют по всей Северной и Южной Америке, вызывая переплетающиеся синдромы фебрилов, которые ставят под сомнение этиологическую диагностику исключительно на основе клинических критериев. Множественные молекулярные платформы на основе картриджа открывают возможности для децентрализованного тестирования в гиперэпидемионных режимах, однако независимые реальные оценки их клинической и аналитической эффективности остаются ограниченны

Background/Objectives: Arboviruses including dengue virus (DENV), Zika virus (ZIKV), chikungunya virus (CHIKV), yellow fever virus (YFV), and West Nile virus (WNV) co-circulate across the Americas, generating overlapping febrile syndromes that challenge etiological diagnosis based solely on clinical criteria. Cartridge-based multiplex molecular platforms off…

Ageing affecting the Americas?: exploring the growth direction: the relationship between the elderly population and economic growth in the American context.

The main aim of this study is to explore the relationship between the elderly population and economic growth in 25 North and South American countries use annual secondary data from 1961 to 2021. Instead of focusing on the conditional mean, this study tests for Granger causality in the entire conditional distribution of the elderly population and economic growth through wavelet coherence analysis. The study findings indicated a unidirectional Granger causality running from per capita gross domestic product (GDP) to the elderly population for Bolivia, Colombia, Guyana, Peru and Puerto Rico and a

An updated systematic review with meta-analysis and meta-regression of the factors associated with human visceral leishmaniasis in the Americas.

BACKGROUND: Human visceral leishmaniasis (VL) is a systemic disease with high case-fatality rates and a widespread distribution. Continuous evaluation of the risk factors for VL is essential to ensure the effective implementation of prevention and control measures. The present study reviews the factors associated with VL in the Americas. METHODS: This systematic review updates a previous 2013 report by including cross-sectional, cohort and case-control studies published between July 2011 and April 2024. Associations between VL and risk factors were analyzed using random-effects meta-analysis,…
