RESUMO
Background: The Amyotrophic Lateral Sclerosis-Parkinsonism-Dementia Complex (ALS-PDC) was first described in the islands of Guam. This pathology presented its peak incidence in the 1950s. Due to the rarity of the association, we report a clinical case with this complex. The objective was to describe the nosological and pathogenic implications of these neurodegenerative disorder, since they are not frequent to find in our population. Clinical case: We present a case of Latinoamerican origin who initially manifested systemic symptoms of more than 6 years of evolution, with subsequent cognitive alterations. Later, patient began with gait disturbances and motor symptoms suggestive of parkinsonism with atypical data and data of motor neurone disease (MND). More studies were carried out and confirmed findings compatible with upper and lower motor neuron involvement. A mutation in the POLG gene was observed, related to mitochondrial depletion syndrome. Conclusion: Despite the knowledge of this association, it is an entity whose clinical diagnosis could be very difficult to achieve. In addition, molecular mechanisms have not been fully identified, the most common genes related to Parkinsonism and ALS have been excluded, and even attempts to locate the locus were made, without achieving accurate results. Unfortunately, being a neurodegenerative disease, the prognosis is fatal, with no disease-modifying treatment.
Introducción: el complejo parkinsonismo-demencia-esclerosis lateral amiotrófica fue descrito por primera vez en las islas de Guam. Esta patología presentó su pico de incidencia en los años 50. Debido a la rareza de la asociación, informamos sobre un caso clínico que la presenta. El objetivo fue describir las implicaciones nosológicas y patogénicas de este trastorno neurodegenerativo, ya que no es frecuente encontrar esta asociación en nuestra población. Caso clínico: presentamos un caso de origen latinoamericano que inicialmente se manifestó con síntomas sistémicos de más de 6 años de evolución, con posteriores alteraciones cognitivas. Después presentó alteraciones de la marcha y síntomas motores sugestivos de parkinsonismo con datos atípicos y datos de enfermedad de motoneurona. Se hicieron estudios de extensión que confirmaron hallazgos compatibles con afectación en motoneurona superior e inferior. Observamos mutación en gen POLG, relacionada con síndrome de depleción mitocondrial. Conclusión: a pesar del conocimiento de esta asociación, es una entidad cuyo diagnóstico clínico puede ser muy difícil de obtener. Además, no se han identificado del todo los mecanismos moleculares, se han excluido los genes más comunes relacionados con parkinsonismos y esclerosis lateral amiotrófica e incluso se intentó localizar el locus, sin lograr resultados certeros. Desafortunadamente al ser una enfermedad neurodegenerativa el pronóstico es fatal, sin que haya tratamiento modificador de la enfermedad.

BACKGROUND: The United States Preventive Services Task Force (USPSTF) recommends breast, cervical, and colorectal cancer screening among eligible adults, but information on screening use in the US territories is limited. METHODS: To estimate the proportion of adults up-to-date with breast, cervical, and colorectal cancer screening based on USPSTF recommendations, we analyzed Behavioral Risk Factor Surveillance System data from 2016, 2018, and 2020 for the 50 US states and DC (US) and US territories of Guam and Puerto Rico and from 2016 for the US Virgin Islands. Age-standardized weighted proportions for up-to-date cancer screening were examined overall and by select characteristics for each jurisdiction. RESULTS: Overall, 67.2% (95% CI: 60.6-73.3) of women aged 50-74 years in the US Virgin Islands, 74.8% (70.9-78.3) in Guam, 83.4% (81.7-84.9) in Puerto Rico, and 78.3% (77.9-78.6) in the US were up-to-date with breast cancer screening. For cervical cancer screening, 71.1% (67.6-74.3) of women aged 21-65 years in Guam, 81.3% (74.6-86.5) in the US Virgin Islands, 83.0% (81.7-84.3) in Puerto Rico, and 84.5% (84.3-84.8) in the US were up-to-date. For colorectal cancer screening, 45.2% (40.0-50.5) of adults aged 50-75 years in the US Virgin Islands, 47.3% (43.6-51.0) in Guam, 61.2% (59.5-62.8) in Puerto Rico, and 69.0% (68.7-69.3) in the US were up-to-date. Adults without health care coverage reported low test use for all three cancers in all jurisdictions. In most jurisdictions, test use was lower among adults with less than a high school degree and an annual household income of < $25,000. CONCLUSION: Cancer screening test use varied between the US territories, highlighting the importance of understanding and addressing territory-specific barriers. Test use was lower among groups without health care coverage and with lower income and education levels, suggesting the need for targeted evidence-based interventions.

The following study explores the geographic distribution of EPA environmental violations across the unincorporated territories within a criminological framework. Using data obtained from the EPA ECHO database, we conduct a geospatial legal analysis to identify island areas bearing a disproportionate number of green criminal activity between 2013 and 2017. Puerto Rico, the U.S. Virgin Islands, Guam, Mariana Islands, and American Samoa reflect a combination of green criminal patterns tied to tourism, commercial production, militarism, and nuclear testing. These remote and relatively biodiverse isles are consistently found to be bearing the burden of toxic waste which originated on the other side of the sea.

The very uncommon alpheid shrimp Bermudacaris britayevi Anker, Poddoubtchenko Marin, 2006, previously known only from the incomplete holotype from Nha Trang Bay, Vietnam, is recorded from Guam, Mariana Islands, extending its previously known distribution range into the oceanic islands of the western Pacific. The single specimen from Guam, an ovigerous female, was collected adjacent to a near-shore coral reef, on fine sand under a large piece of coral rubble, at a depth of about 10 m. This habitat is different from the collection data of the holotype, which was extracted from a burrow of unknown host on an intertidal sand-mud flat close to mangroves. Despite these ecological differences, the specimen from Guam corresponds to the holotype of B. britayevi in all diagnostic morphological characters and can be distinguished from the closely related B. australiensis Anker Komai, 2004 and B. harti Anker Iliffe, 2000. Since the holotype of B. britayevi was lacking one of the chelipeds, the complete specimen from Guam enables to complement the original description of the species. The stouter (= major) cheliped of the Guam specimen is illustrated to show a marked difference in the armature of the cheliped fingers, between the left and right cheliped. The colour pattern of B. britayevi, which was superficially described in the original description, is herein illustrated by photographs of the living individual. The relatively low number and large size of eggs in the Guam specimen of B. britayevi suggests an abbreviated larval development in this species.

PROBLEM: Chronic conditions and disorders (e.g., diabetes, cardiovascular diseases, arthritis, and depression) are leading causes of morbidity and mortality in the United States. Healthy behaviors (e.g., physical activity, avoiding cigarette use, and refraining from binge drinking) and preventive practices (e.g., visiting a doctor for a routine check-up, tracking blood pressure, and monitoring blood cholesterol) might help prevent or successfully manage these chronic conditions. Monitoring chronic diseases, health-risk behaviors, and access to and use of health care are fundamental to the development of effective public health programs and policies at the state and local levels. REPORTING PERIOD: January-December 2015. DESCRIPTION OF THE SYSTEM: The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing, state-based, random-digit-dialed landline- and cellular-telephone survey of noninstitutionalized adults aged ≥18 years residing in the United States. BRFSS collects data on health-risk behaviors, chronic diseases and conditions, access to and use of health care, and use of preventive health services related to the leading causes of death and disability. This report presents results for all 50 states, the District of Columbia, the Commonwealth of Puerto Rico (Puerto Rico), and Guam and for 130 metropolitan and micropolitan statistical areas (MMSAs) (N = 441,456 respondents) for 2015. RESULTS: The age-adjusted prevalence estimates of health-risk behaviors, self-reported chronic health conditions, access to and use of health care, and use of preventive health services varied substantially by state, territory, and MMSA in 2015. Results are summarized for selected BRFSS measures. Each set of proportions refers to the median (range) of age-adjusted prevalence estimates for health-risk behaviors, self-reported chronic diseases or conditions, or use of preventive health care services by geographic jurisdiction, as reported by survey respondents. Adults with good or better health: 84.6% (65.9%-88.8%) for states and territories and 85.2% (66.9%-91.3%) for MMSAs. Adults with ≥14 days of poor physical health in the past 30 days: 10.9% (8.2%-17.2%) for states and territories and 10.9% (6.6%-19.1%) for MMSAs. Adults with ≥14 days of poor mental health in the past 30 days: 11.3% (7.3%-15.8%) for states and territories and 11.4% (5.6%-20.5%) for MMSAs. Adults aged 18-64 years with health care coverage: 86.8% (72.0%-93.8%) for states and territories and 86.8% (63.2%-95.7%) for MMSAs. Adults who received a routine physical checkup during the preceding 12 months: 69.0% (58.1%-79.8%) for states and territories and 69.4% (57.1%-81.1%) for MMSAs. Adults who ever had their blood cholesterol checked: 79.1% (73.3%-86.7%) for states and territories and 79.5% (65.1%-87.3%) for MMSAs. Current cigarette smoking among adults: 17.7% (9.0%-27.2%) for states and territories and 17.3% (4.5%-29.5%) for MMSAs. Binge drinking among adults during the preceding 30 days: 17.2% (11.2%-26.0%) for states and territories and 17.4% (5.5%-24.5%) for MMSAs. Adults who reported no leisure-time physical activity during the preceding month: 25.5% (17.6%-47.1%) for states and territories and 24.5% (16.1%-47.3%) for MMSAs. Adults who reported consuming fruit less than once per day during the preceding month: 40.5% (33.3%-55.5%) for states and territories and 40.3% (30.1%-57.3%) for MMSAs. Adults who reported consuming vegetables less than once per day during the preceding month: 22.4% (16.6%-31.3%) for states and territories and 22.3% (13.6%-32.0%) for MMSAs. Adults who have obesity: 29.5% (19.9%-36.0%) for states and territories and 28.5% (17.8%-41.6%) for MMSAs. Adults aged ≥45 years with diagnosed diabetes: 15.9% (11.2%-26.8%) for states and territories and 15.7% (10.5%-27.6%) for MMSAs. Adults aged ≥18 years with a form of arthritis: 22.7% (17.2%-33.6%) for states and territories and 23.2% (12.3%-33.9%) for MMSAs. Adults having had a depressive disorder: 19.0% (9.6%-27.0%) for states and territories and 19.2% (9.9%-27.2%) for MMSAs. Adults with high blood pressure: 29.1% (24.2%-39.9%) for states and territories and 29.0% (19.7%-41.0%) for MMSAs. Adults with high blood cholesterol: 31.8% (27.1%-37.3%) for states and territories and 31.4% (23.2%-42.0%) for MMSAs. Adults aged ≥45 years who have had coronary heart disease: 10.3% (7.2%-16.8%) for states and territories and 10.1% (4.7%-17.8%) for MMSAs. Adults aged ≥45 years who have had a stroke: 4.9% (2.5%-7.5%) for states and territories and 4.7% (2.1%-8.4%) for MMSAs. INTERPRETATION: The prevalence of health care access and use, health-risk behaviors, and chronic health conditions varied by state, territory, and MMSA. The data in this report underline the importance of continuing to monitor chronic diseases, health-risk behaviors, and access to and use of health care in order to assist in the planning and evaluation of public health programs and policies at the state, territory, and MMSA level. PUBLIC HEALTH ACTION: State and local health departments and agencies and others interested in health and health care can continue to use BRFSS data to identify groups with or at high risk for chronic conditions, unhealthy behaviors, and limited health care access and use. BRFSS data also can be used to help design, implement, monitor, and evaluate health-related programs and policies.

AIMS: Although U.S. territories fall within the mandate outlined by Healthy People 2020, they remain neglected in diabetes care research. We compared the prevalence and secular trends of four recommended diabetes care practices in the U.S. territories of Guam, Puerto Rico, and the U.S. Virgin Islands to the 50 United States and D.C. ("U.S. States") in 2001-2015. METHODS: Data were from 390,268 adult participants with self-reported physician diagnosed diabetes in the Behavioral Risk Factor Surveillance System. Diabetes care practices included biannual HbA1c tests, attendance of diabetes education classes, daily self-monitoring of blood glucose, and receipt of annual foot examination. Practices were compared by U.S. territory and between territories and U.S. states. Multivariable models accounted for age, sex, education, and year. RESULTS: Of adults with diagnosed diabetes, 7% to 11% in the U.S. territories engaged in all four recommended diabetes care practices compared with 25% for those, on average, in U.S. states. Relative to the U.S. states, on average, the proportion achieving biannual HbA1c testing was lower in Guam and the U.S. Virgin Islands (45.6% and 44.9% vs. 62.2%), while annual foot examinations were lower in Puerto Rico (45.9% vs 66.1% in the U.S. states). Diabetes education and daily glucose self-monitoring were lower in all three territories. CONCLUSIONS: U.S. territories lag behind U.S. states in diabetes care practices. Policies aimed at improving diabetes care practices are needed in the U.S. territories to achieve Healthy People 2020 goals and attain parity with U.S. states.

Electronic cigarettes (e-cigarettes) are the most frequently used tobacco product among U.S. youths, and past 30-day e-cigarette use is more prevalent among high school students than among adults (1,2). E-cigarettes typically deliver nicotine, and the U.S. Surgeon General has concluded that nicotine exposure during adolescence can cause addiction and can harm the developing adolescent brain (2). Through authority granted by the Family Smoking Prevention and Tobacco Control Act, the Food and Drug Administration (FDA) prohibits e-cigarette sales to minors, free samples, and vending machine sales, except in adult-only facilities (3). States, localities, territories, and tribes maintain broad authority to adopt additional or more stringent requirements regarding tobacco product use, sales, marketing, and other topics (2,4). To understand the current e-cigarette policy landscape in the United States, CDC assessed state and territorial laws that 1) prohibit e-cigarette use and conventional tobacco smoking indoors in restaurants, bars, and worksites; 2) require a retail license to sell e-cigarettes; 3) prohibit e-cigarette self-service displays (e.g., requirement that products be kept behind the counter or in a locked box); 4) establish 21 years as the minimum age of purchase for all tobacco products, including e-cigarettes (tobacco-21); and 5) apply an excise tax to e-cigarettes. As of September 30, 2017, eight states, the District of Columbia (DC), and Puerto Rico prohibited indoor e-cigarette use and smoking in indoor areas of restaurants, bars, and worksites; 16 states, DC, and the U.S. Virgin Islands required a retail license to sell e-cigarettes; 26 states prohibited e-cigarette self-service displays; five states, DC, and Guam had tobacco-21 laws; and eight states, DC, Puerto Rico, and the U.S. Virgin Islands taxed e-cigarettes. Sixteen states had none of the assessed laws. A comprehensive approach that combines state-level strategies to reduce youths' initiation of e-cigarettes and population exposure to e-cigarette aerosol, coupled with federal regulation, could help reduce health risks posed by e-cigarettes among youths (2,5).

PROBLEM: Chronic diseases and conditions (e.g., heart diseases, stroke, arthritis, and diabetes) are the leading causes of morbidity and mortality in the United States. These conditions are costly to the U.S. economy, yet they are often preventable or controllable. Behavioral risk factors (e.g., excessive alcohol consumption, tobacco use, poor diet, frequent mental distress, and insufficient sleep) are linked to the leading causes of morbidity and mortality. Adopting positive health behaviors (e.g., staying physically active, quitting tobacco use, obtaining routine physical checkups, and checking blood pressure and cholesterol levels) can reduce morbidity and mortality from chronic diseases and conditions. Monitoring the health risk behaviors, chronic diseases and conditions, access to health care, and use of preventive health services at multilevel public health points (states, territories, and metropolitan and micropolitan statistical areas [MMSA]) can provide important information for development and evaluation of health intervention programs. REPORTING PERIOD: 2013 and 2014. DESCRIPTION OF THE SYSTEM: The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing, state-based, random-digit-dialed telephone survey of noninstitutionalized adults aged ≥18 years residing in the United States. BRFSS collects data on health risk behaviors, chronic diseases and conditions, access to health care, and use of preventive health services and practices related to the leading causes of death and disability in the United States and participating territories. This is the first BRFSS report to include age-adjusted prevalence estimates. For 2013 and 2014, these age-adjusted prevalence estimates are presented for all 50 states, the District of Columbia, the Commonwealth of Puerto Rico, Guam, and selected MMSA. RESULTS: Age-adjusted prevalence estimates of health status indicators, health care access and preventive practices, health risk behaviors, chronic diseases and conditions, and cardiovascular conditions vary by state, territory, and MMSA. Each set of proportions presented refers to the range of age-adjusted prevalence estimates of selected BRFSS measures as reported by survey respondents. The following are estimates for 2013. Adults reporting frequent mental distress: 7.7%-15.2% in states and territories and 6.3%-19.4% in MMSA. Adults with inadequate sleep: 27.6%-49.2% in states and territories and 26.5%-44.4% in MMSA. Adults aged 18-64 years having health care coverage: 66.9%-92.4% in states and territories and 60.5%-97.6% in MMSA. Adults identifying as current cigarette smokers: 10.1%-28.8% in states and territories and 6.1%-33.6% in MMSA. Adults reporting binge drinking during the past month: 10.5%-25.2% in states and territories and 7.2%-25.3% in MMSA. Adults with obesity: 21.0%-35.2% in states and territories and 12.1%-37.1% in MMSA. Adults aged ≥45 years with some form of arthritis: 30.6%-51.0% in states and territories and 27.6%-52.4% in MMSA. Adults aged ≥45 years who have had coronary heart disease: 7.4%-17.5% in states and territories and 6.2%-20.9% in MMSA. Adults aged ≥45 years who have had a stroke: 3.1%-7.5% in states and territories and 2.3%-9.4% in MMSA. Adults with high blood pressure: 25.2%-40.1% in states and territories and 22.2%-42.2% in MMSA. Adults with high blood cholesterol: 28.8%-38.4% in states and territories and 26.3%-39.6% in MMSA. The following are estimates for 2014. Adults reporting frequent physical distress: 7.8%-16.0% in states and territories and 6.2%-18.5% in MMSA. Women aged 21-65 years who had a Papanicolaou test during the past 3 years: 67.7%-87.8% in states and territories and 68.0%-94.3% in MMSA. Adults aged 50-75 years who received colorectal cancer screening on the basis of the 2008 U.S. Preventive Services Task Force recommendation: 42.8%-76.7% in states and territories and 49.1%-79.6% in MMSA. Adults with inadequate sleep: 28.4%-48.6% in states and territories and 25.4%-45.3% in MMSA. Adults reporting binge drinking during the past month: 10.7%-25.1% in states and territories and 6.7%-26.3% in MMSA. Adults aged ≥45 years who have had coronary heart disease: 8.0%-17.1% in states and territories and 7.6%-19.2% in MMSA. Adults aged ≥45 years with some form of arthritis: 31.2%-54.7% in states and territories and 28.4%-54.7% in MMSA. Adults with obesity: 21.0%-35.9% in states and territories and 19.7%-42.5% in MMSA. INTERPRETATION: Prevalence of certain chronic diseases and conditions, health risk behaviors, and use of preventive health services varies among states, territories, and MMSA. The findings of this report highlight the need for continued monitoring of health status, health care access, health behaviors, and chronic diseases and conditions at state and local levels. PUBLIC HEALTH ACTION: State and local health departments and agencies can continue to use BRFSS data to identify populations at risk for certain unhealthy behaviors and chronic diseases and conditions. Data also can be used to design, monitor, and evaluate public health programs at state and local levels.

Xylographellini beetles occur mainly in lands of the Southern Hemisphere. However, the taxonomy of Australian and Oriental species is incipient. The tribe comprises four genera, of which Scolytocis Blair, 1928 and XylographellaMiyatake, 1985 were recently redescribed and reported from Australia but without descriptions of new species. Here, three new species of Xylographellini are described: Scolytocis australimontensis sp. n. from Australia, with smooth interspaces of pronotal punctures; Scolytocis insularis sp. n.from the Pohnpei Island (Caroline Islands, Micronesia), with microstriated interspaces of pronotal punctures; and Xylographella frithae sp. n. from Australia, with six raised keels in elytral declivity. Scolytocis samoensis Blair, 1928, type species of the genus, is recorded from Guam (Mariana Islands, Micronesia) and redescribed. Keys for the Scolytocis and Xylographella occurring in the Australian and Oriental regions are also provided.(AU)
