This study aims to investigate flaviviruses as an environmental factor in the etiology of nonsyndromic cleft lip and/or palate (CL/P). A scoring method with 7 topics-disease, transplacental passage, tropism, cellular damage, reported case, analysis of genome similarity, and transcriptome between virus and host, was created based on literature and experimentation. Viral genomes of NCBI virus were obtained and BLAST 2.12.0 was applied for the similarity analysis, adjusted to search for only human sequences related to CL/P with the statistical threshold defined for E-value ≤1. Flaviviruses with high potential to cause CL/P were: serotypes 2, 3, and 4 of the and lineage 2 of the , while the , , , and presented with medium potential to cause CL/P. As for the , even strains associated with microcephaly showed only medium potential. and presented with high potential to act as environmental factors in the etiology of CL/P.

Background: Japanese encephalitis (JE) is a zoonotic parasitic disease caused by the Japanese encephalitis virus (JEV), and may cause fever, nausea, headache, or meningitis. It is currently unclear whether the epidemiological characteristics of the JEV have been affected by the extreme climatic conditions that have been observed in recent years.

Objective: This study aimed to examine the epidemiological characteristics, trends, and potential risk factors of JE in Taiwan from 2008 to 2020.

Background: Comprehensive clinical data regarding factors influencing the individual disease course of patients with movement disorders treated with deep brain stimulation might help to better understand disease progression and to develop individualized treatment approaches.

Methods: The clinical core data set was developed by a multidisciplinary working group within the German transregional collaborative research network ReTune. The development followed standardized methodology comprising review of available evidence, a consensus process and performance of the first phase of the study.

Background: According to WHO, "noncommunicable diseases (NCDs) kill 41 million people" annually, as the primary cause of death globally. WHO's Global Action Plan for the prevention and control of NCDs 2013-2020 (extended) tackles this issue and its implications regarding inequalities between countries and populations. Based on combined behavioural, environmental and policy approaches, health promotion aims to reduce health inequities and address health determinants through 3 strategies: education, prevention and protection.

Background: Genital inflammation increases HIV susceptibility and is associated with the density of pro-inflammatory anaerobes in the vagina and coronal sulcus. The penile urethra is a critical site of HIV acquisition, although correlates of urethral HIV acquisition are largely unknown. While Streptococcus mitis is a consistent component of the urethral flora, the presence of Gardnerella vaginalis has been linked with prior penile-vaginal sex and urethral inflammation.

Background: Older patients hospitalized in acute care settings are at significant risk of presenting hospital-acquired conditions. Healthcare professionals should consider many factors involved in the development of such conditions, including factors related to the patients, as well as those related to the processes of care and the structure of hospitals. The aim of this study was to describe and identify the factors involved in the development of hospital-acquired conditions in older patients in acute care settings.
