Orthopedic surgery in Palau-Current capacity, needs, and future directions.

Background: Palau, an island nation in Micronesia, is a medically underserved area with a shortage of specialty care services. Orthopedic diagnoses in Palau remain among the three most common reasons for costly off-island medical referral. The purpose of this study was to assess Palau's current orthopedic surgery capacity and needs to inform interventions to build capacity to improve care access and quality.

The Current Status of Telehealth and Distance Learning in Palau.

In 2017 the Republic of Palau installed fiber optic cables, allowing access to high speed internet for the first time and the capacity for growth in telehealth. Given Palau's poor access to specialists and resources, telehealth has the potential to radically change health care delivery. Currently, the status of telehealth in Palau is unknown.

The accuracy of a portable sleep monitor to diagnose obstructive sleep apnea in adolescent patients.

Study Objectives: The efficacy of portable-monitor (PM) sleep testing in children is not well understood. While most studies have evaluated PM in a lab setting, the utility of PM in the home environment is relatively unknown. We sought to determine whether home PM accurately diagnoses obstructive sleep apnea in adolescents and to assess patient satisfaction with home PM sleep testing.

Findings of routine nocturnal polysomnography in children with Down syndrome: a retrospective cohort study.

Study Objective: Children with Down syndrome (DS) are at risk for sleep disorders including; obstructive sleep apnea (OSA). Although OSA is diagnosed by polysomnography (PSG), the practicality of PSG in DS is questionable. Further, OSA treatment efficacy in DS is largely unknown given the challenges of PSG.

Artery Tertiary Lymphoid Organs Control Aorta Immunity and Protect against Atherosclerosis via Vascular Smooth Muscle Cell Lymphotoxin β Receptors.

Tertiary lymphoid organs (TLOs) emerge during nonresolving peripheral inflammation, but their impact on disease progression remains unknown. We have found in aged Apoe(-/-) mice that artery TLOs (ATLOs) controlled highly territorialized aorta T cell responses. ATLOs promoted T cell recruitment, primed CD4(+) T cells, generated CD4(+), CD8(+), T regulatory (Treg) effector and central memory cells, converted naive CD4(+) T cells into induced Treg cells, and presented antigen by an unusual set of dendritic cells and B cells.

In vivo real-time multiphoton imaging of T lymphocytes in the mouse brain after experimental stroke.

Background And Purpose: To gain a better understanding of T cell behavior after stroke, we have developed real-time in vivo brain imaging of T cells by multiphoton microscopy after middle cerebral artery occlusion.

Methods: Adult male hCD2-GFP transgenic mice that exhibit green fluorescent protein-labeled T cells underwent permanent left distal middle cerebral artery occlusion by electrocoagulation (n=6) or sham surgery (n=6) and then multiphoton laser imaging 72 hours later.

Results: Extravasated T cell number significantly increased after middle cerebral artery occlusion versus sham.

Advances in imaging of new targets for pharmacological intervention in stroke: real-time tracking of T-cells in the ischaemic brain.

Background And Purpose: T-cells may play a role in the evolution of ischaemic damage and repair, but the ability to image these cells in the living brain after a stroke has been limited. We aim to extend the technique of real-time in situ brain imaging of T-cells, previously shown in models of immunological diseases, to models of experimental stroke.

Experimental Approach: Male C57BL6 mice (6-8 weeks) (n= 3) received a total of 2-5 x 10(6) carboxyfluorescein diacetate succinimidyl ester (CFSE)-labelled lymphocytes from donor C57BL6 mice via i.

Imaging T-cell movement in the brain during experimental cerebral malaria.

T-cells are known to play a role in the pathology associated with experimental cerebral malaria, although it has not previously been possible to examine their behaviour in brain. Using multiphoton laser scanning microscopy, we have examined the migration and movement of these cells in brain tissue. We believe that this approach will help define host-parasite interactions and examine how intervening in these relationships affects the development of cerebral pathology.

Single nucleotide polymorphism and lifestyle-related diseases in the Asia-Pacific region: comparative study in Okinawa, Palau and Thailand.

Genetic differences between Asians and Caucasians may be involved in the rapid increase in lifestyle-related diseases in the Asia-Pacific region that has coincided with Westernisation of diets in the region. In the present study, we assessed correlation between 10 single nucleotide polymorphisms (SNPs) and chronic disease risk factors in age-matched and population-based groups in four Asian-Pacific locations: Okinawa, Palau and Thailand (two areas). The following allelic SNP profiles significantly differed (p<0.

The use of appropriateness criteria for the selection of clinical preventive services for a Pacific island health service.

Clinical preventive services are measures performed in the clinic setting for the prevention of disease and the promotion of health. The general practice/public health physician residency class of the Palau Area Health Education Center reviewed existing clinical preventive services protocols for the Ministry of Health of the Republic of Palau and revised them, taking four criteria into consideration for each candidate intervention (local patterns of disease and risk factors, evidence for effectiveness of the intervention, local system capability for delivery of the intervention and its consequences, and competing priorities). The resulting package of interventions is much more focused and appropriate to local conditions than was the one that it replaced.

The Palau AHEC--academizing the public health work plan: capacity development and innovation in Micronesia.

The Palau Area Health Education Center (AHEC)--a program of the University of Hawaii's John A. Burns School of Medicine (JABSOM) and based at Palau Community College--was established in 2001 in response to the recommendations of the 1998 Institute of Medicine (IOM) report--Pacific Partnerships for Health--Charting a New Course for the 21st Century1. One of IOM's core recommendations was to promote the training of the primary health care workforce among the U.

Palau's current and future capacity for disaster management.

Despite the challenges of geographic isolation, a small population and limited financial resources, the Republic of Palau has been able to significantly improve its ability to address disasters through establishing an emergency health program funded by US Federal Grants. The ability to prevent and respond to ordinary emergencies and disasters has been bolstered by creating electronic Public Health and Hospital Emergency Operations Plans, improving and creating hospital surge capacity infrastructure in all units beyond recommended minimums, initiating a database of volunteers with disaster response related skills, creating pharmacy caches, developing a national HAZAMT team, teaching critical incident stress debriefing skills, creating and expanding communications networks, improving the pre-hospital care system, conducting active disease surveillance, and improving the scope and quality of lab services. New policies and procedures are implemented and sustained through an active education system incorporating drills, exercises and didactic teaching sessions.

Human resource development in environmental health for Palau--a model program for Micronesia and the Pacific.

In Palau, prior to 1997, the highest degree qualification in Sanitation Division (now called Division of Environmental Health) under the Bureau of Public Health, Ministry of Health, was a Diploma in Environmental Health from the Fiji School of Medicine. By September 2003, during an Environmental Health Planning and Management Workshop (NEHAP), Human Resource Development (HRD) was declared as a priority area and therefore was incorporated into the Palau National Environmental Health Action Plan. The Palau NEHAP HRD goal is to develop a human resource development plan for environmental health, which builds a career ladder with incentives.

The Pacific Center for Emergency Health--an anatomy of collaborative development and change--the Palau perspective.

Many Pacific Islands Countries (PICs) by their geographic location, isolation, and lack of resources, are at risk for both environmental and man-made disasters. Disaster management (DM) and mitigation is frustrated by the general underdevelopment of DM planning and lack of adequate emergency medical services (EMS) to deal with daily emergencies let alone large-scale emergencies and disasters. To address this, the U.

Phospholipid chlorohydrin induces leukocyte adhesion to ApoE-/- mouse arteries via upregulation of P-selectin.

HOCl-modified low-density lipoprotein (LDL) has proinflammatory effects, including induction of inflammatory cytokine production, leukocyte adhesion, and ROS generation, but the components responsible for these effects are not completely understood. HOCl and the myeloperoxidase-H(2)O(2)-halide system can modify both protein and lipid moieties of LDL and react with unsaturated phospholipids to form chlorohydrins. We investigated the proinflammatory effects of 1-stearoyl-2-oleoyl-sn-3-glycerophosphocholine (SOPC) chlorohydrin on artery segments and spleen-derived leukocytes from ApoE(-/-) and C57 Bl/6 mice.

The Yap AHEC: an update 2002-2006.

The Yap Area Health Education Center (AHEC) is one of three U.S. Health Resources and Services Administration-funded AHEC programs in the U.

Palau assessment for a continuing health care professional development program.

In 2003, the University of Hawai'i Department of Family Medicine and Community Health entered a 4-year cooperative agreement with the U.S. Health Resources and Services Administration to establish the "Pacific Association for Clinical Training" (PACT).

Fatty acid and phospholipid chlorohydrins cause cell stress and endothelial adhesion.

The oxidation of low-density lipoprotein (LDL) is thought to contribute to atherogenesis, which is an inflammatory disease involving activation of phagocytic cells. Myeloperoxidase, an enzyme which is able to produce hypochlorous acid (HOCl), is released from these phagocytic cells, and has been found in an active form in atherosclerotic plaques. HOCl can oxidize both the lipid and protein moiety of LDL, and HOCl-modified LDL has been found to be pro-inflammatory, although it is not known which component is responsible for this effect.

The Palau Early Psychosis Study: distribution of cases by level of genetic risk.

The Palau Early Psychosis Study (PEPS) was designed to examine the pathogenesis of early psychosis in a high-risk population isolate. This paper describes the characteristics of our community-based, non-help seeking sample of 404 Palauan adolescents and quantifies the presence of early psychosis by level of genetic risk. The sample included 53 offspring of a schizophrenic parent designated as "Genetically Highest Risk" (GHR+) and 68 nieces/nephews of sib-pairs/trios, designated as "Genetically High Risk" (GHR).

The nitric oxide-donating pravastatin derivative, NCX 6550 [(1S-[1alpha(betaS*, deltaS*), 2alpha, 6alpha, 8beta-(R*), 8a alpha]]-1,2,6,7,8,8a-Hexahydro-beta, delta, 6-trihydroxy-2-methyl-8-(2-methyl-1-oxobutoxy)-1-naphtalene-heptanoic acid 4-(nitrooxy)butyl ester)], reduces splenocyte adhesion and reactive oxygen species generation in normal and atherosclerotic mice.

Statins possess anti-inflammatory effects that may contribute to their ability to slow atherogenesis, whereas nitric oxide (NO) also influences inflammatory cell adhesion. This study aimed to determine whether a novel NO-donating pravastatin derivative, NCX 6550 [(1S-[1alpha(betaS*,deltaS*),2alpha,6alpha,8beta-(R*),8a alpha]]-1,2,6,7,8,8a-hexahydro-beta,delta,6-trihydroxy-2-methyl-8-(2-methyl-1-oxobutoxy)-1-naphthalene-heptanoic acid 4-(nitrooxy)butyl ester)], has greater anti-inflammatory properties compared with pravastatin in normal and atherosclerotic apolipoprotein E receptor knockout (ApoE-/-) mice. C57BL/6 and ApoE-/- mice were administered pravastatin (40 mg/kg), NCX 6550 (48.

Studies of phospholipid oxidation by electrospray mass spectrometry: from analysis in cells to biological effects.

The oxidation of lipids is important in many pathological conditions and lipid peroxidation products such as 4-hydroxynonenal (HNE) and other aldehydes are commonly measured as biomarkers of oxidative stress. However, it is often useful to complement this with analysis of the original oxidized phospholipid. Electrospray mass spectrometry (ESMS) provides an informative method for detecting oxidative alterations to phospholipids, and has been used to investigate oxidative damage to cells, and low-density lipoprotein, as well as for the analysis of oxidized phosphatidylcholines present in atherosclerotic plaque material.
