Tagalog
Tagalog is a member of the Central Philippine subgroup of Philippine languages, forming part of the Western-Malayo-Polynesian set of Austronesian languages. It belongs in a subgroup with Bikol, Bisayan and Mansakan languages and was originally probably native to the eastern Visayas or northeast Mindanao in the Central Philippines (Zorc 1993). By the time the Spanish arrived in the Philippines (1521), Tagalog speakers had migrated north into the southern part of the island of Luzon in the Philippines, with Tagalog becoming the major language spoken in Manila and surrounding provinces; it has in recent years spread as a second language over virtually the entire Philippine archipelago. Thus, while only about a quarter of the population of the Philippines were Tagalog-speaking in 1940, in 1970 approximately half of the population were, and today it is estimated that well over 90 per cent of the 80 million total population of the Philippines is either a first- or second-language speaker of the language
Pulmonary function evaluation during and following Skylab space flights
Previous experience during the Apollo postflight exercise testing indicated no major changes in pulmonary function. Although pulmonary function has been studied in detail following exposure to hypoxic and hyperoxic environments, few studies have dealt with normoxic environments at reduced total pressure as encountered during the Skylab missions. Forced vital capacity was measured during the preflight and postflight periods of the Skylab 2 mission. Initial in-flight measurements of vital capacity were obtained during the last two weeks of the second manned mission (Skylab 3). Comprehensive pulmonary function screening was accomplished during the Skylab 4 mission. The primary measurements made during Skylab 4 testing included residual volume determination, closing volume, vital capacity, and forced vital capacity and its derivatives. In addition, comprehensive in-flight vital capacity measurements were made during the Skylab 4 mission. Vital capacity was decreased slightly during flight in all Skylab 4 crewmen. No major preflight to postflight changes were observed in the other parameters

The effectiveness of disinfection protocols in medical school osteopathic manipulative medicine labs.
CONTEXT: In light of the COVID-19 pandemic, healthcare-associated infections have taken center stage. Healthcare has adjusted workflows to accommodate for more robust disinfecting regiments to help protect the community. This has resulted in the need for medical institutions to reevaluate the current disinfection protocols down to the student level. The osteopathic manipulative medicine (OMM) laboratory provides an optimal avenue for assessing the effectiveness of medical students\u27 ability to clean examination tables. With OMM laboratories having a high level of interaction, adequate disinfection is important for the health and safety of students and teaching faculties.
OBJECTIVES: This study will evaluate the effectiveness of the current disinfection protocols in the medical school OMM labs.
METHODS: A cross-sectional, nonrandomized study was performed on 20 OMM examination tables utilized for osteopathic training. Tables were chosen based on their close proximity to the podium. Close proximity was utilized as a criteria to increase the probability of utilization by students. The sampled tables were observed to ensure their use by students during class. Initial samples were collected in the morning after disinfection by Environmental Services. Terminal samples were collected after Osteopathic medical students utilized and disinfected the OMM examination tables. Samples were collected from the face-cradle and midtorso regions and analyzed utilizing adenosine triphosphate (ATP) bioluminescence assays with an AccuPoint Advanced HC Reader. This reader provides a digital readout of the quantity of light measured in relative light units (RLUs), which is directly correlated to the amount of ATP present in the sample, providing an estimated pathogen count. For statistical analysis, a Wilcoxon signed-rank test was utilized to find statistical differences in RLUs in samples after initial and terminal disinfection.
RESULTS: The face cradle showed a 40 % increase in failure rate in samples after terminal disinfection when samples were compared after initial disinfection. A Wilcoxon signed-rank test revealed an estimated pathogen level for face cradle that was significantly higher after terminal disinfection (median, 4,295 RLUs; range, 2,269-12919 RLUs; n=20) compared to initial disinfection (median, 769 RLUs; range, 29-2,422 RLUs; n=20),
CONCLUSIONS: This study suggests that medical students frequently failed to disinfect high-touch regions on examination tables, such as the midtorso and the face cradle. It is recommended that the current OMM lab disinfection protocol be modified to include the disinfection of high-touch regions in order to reduce the possibility of pathogen transmission. Further research should explore the effectiveness of disinfection protocols in clinical settings such as outpatient offices
Developing an Action Learning Community Advocacy/Leadership Training Program for Community Health Workers and Their Agencies to Reduce Health Disparities in Arizona Border Communities
Community health workers (CHWs) make unique and important contributions to society. They serve as patient advocates, educators, and navigators in our health care system and a growing body of research indicates that they play an important role in the effective delivery of prevention and treatment services in underserved communities. CHWs also serve as informal community leaders and advocates for organizational and community change, providing valuable insiders\u27 insights about health promotion and the interrelatedness of individuals, their community, its institutions, and the surrounding environment. Accion Para La Salud or Action for Health (Accion) is a CDC-funded community based participatory research (CBPR) project addressing the social determinants of health affecting health-related behaviors with the ultimate goal of creating a mode in which community advocacy to address the systems and environmental factors influencing health is integrated into the role of CHWs working in chronic disease prevention. Kingdon\u27s three streams theory and the social ecological model provide an overarching conceptual framework for Accion. The curriculum and training are also grounded in the theory and principles of action learning, which emphasizes learning by doing, teamwork, real-world projects, and reflection. The curriculum was delivered in four workshops over thirteen months and included longitudinal team projects, peer support conference calls, and technical assistance visits. It is now being delivered to new groups of CHWs in Arizona using a condensed two-day workshop format
Characterization of the Horizontal and Vertical Sexual Transmission of Chlamydia Genital Infections in a New Mouse Model.
Chlamydia trachomatis is the most common sexually transmitted bacterial pathogen worldwide, and there is a need to control this epidemic. So far there is no established animal model in which both the horizontal and the vertical transmission of Chlamydia can be studied. To implement a horizontal sexual transmission model, male mice were inoculated in the meatus urethra with Chlamydia muridarum and they were caged with naive female mice. Urine and vaginal swab specimens were collected for culture. To study vertical transmission, newborns were euthanized and specimens were cultured. As controls, females were mated with sham-infected male mice. All C. muridarum-inoculated male mice had positive urine cultures. As determined by serology, all females caged with C. muridarum-inoculated males became infected, and 93% of them had positive vaginal swab specimen cultures. More females mated with C. muridarum-infected male mice (35%) than females mated with sham-infected male mice (0%) were infertile (P < 0.05). Also, C. muridarum-infected females delivered significantly fewer pups (3.8 ± 3.2/mouse) than control females (6.3 ± 1.6/mouse) (P < 0.05). Of the newborn mice, 32% were C. muridarum positive either in the lungs or in the intestines. Female mice housed with sham-infected males had no positive vaginal swab specimen cultures or C. muridarum-positive pups. This new mouse model of horizontal and vertical sexual transmission of Chlamydia closely parallels C. trachomatis sexual transmission in humans and may be a good model system to better understand the pathogenesis of these infections
Slow Epidemic of Lymphogranuloma Venereum L2b Strain
We traced the Chlamydia trachomatis L2b variant in Amsterdam and San Francisco. All recent lymphogranuloma venereum cases in Amsterdam were caused by the L2b variant. This variant was also present in the 1980s in San Francisco. Thus, the current "outbreak" is most likely a slowly evolving epidemic
