OBJECTIVE: To discuss the various factors contributory to the fatalities that resulted from the sinking of the MV Dona Paz.

METHODS: Review of the pre-disaster, disaster and post-disaster events surrounding the sinking of the MV Dona Paz, as well as the subsequent response by the government and responsible agencies to the disaster.

RESULTS: The Sinking of the MV Dona Paz, along with the loss of more than 4,000 precious lives, is but a footnote in the long litany of misfortunes plaguing the Philippine maritime industry. A closer look into the events and circumstances leading to this tragedy demonstrates a confluence of equipment and system inadequacy on one hand and human error and lack of preparedness on the other.

CONCLUSION: Multiple factors account for the occurence of this tragedy, along with other maritime disaster incidents dotting the long maritime history of the Philippines. A cursory analysis of these factors may lead to recommendations that can prevent similar occurrences in the future and mitigate damage to property and loss of life. The policy implications of these findings are discussed in a subsequent paper.

Osteoarthdtis (OA) is a common, chronic, and painful disorder characterized by cartilage loss. It is the most common among all rheumatic disorders and is a major cause of disability. OA can be managed with a variety of pharmacological therapies, including acetaminophen, traditional nonsteroidal antiinflammatory drugs, cyclooxygenase2 inhibitors, intraarticular steroids, viscosupplements, glucosamine, chondroitin sulfate, and capsaicin. In this review, I describe the clinical efficacy and side effects of these pharmaceuticals and review diseasemodifying osteoarthritis drugs (DMOAD), such as glucosamine, diacerein, and avocado/soybean unsaponifiables, of which the clinical efficacy still remains to be determined.

OBJECTIVE: To discuss the various factors contributory to maritime disaster preparedness in the Philippines, in the context of the sinking of the MV Dona Paz and formulate recommendations to address these factors.

METHOD: Review of the state of maritime preparedness in the pre-disaster setting and the post-disaster response following the sinking of the MV Dona Paz by the government and responsible agencies. A scrutiny of the state of preparedness of concerned agencies and subsequent response to the disaster was conducted with the objective of formulating recommendations which may lead to prevention and mitigate loss of lives.

RESULTS: Multiple factors accounted for the occurrence of this tragedy. These factors include an inherent risk due to the geography of shipping industry and its labor force. Economic conditions prevent both the industry and government agencies from upgrading vessels and communications equipment. Lack of enforcement of existing regulations allows vessels to sail overloaded and at times manned by less-than-qualified crew. Delayed response and deficient post-disaster medical response may have led to a disproportionately high mortality.

CONCLUSIONS: The systems inadequacies of the Philippine maritime disaster response mechanism are highlighted by the Dona Paz tragedy. Many of the factors contributing to the disproportionately high incidence of maritime disasters in the Philippines and the resulting loss of limb may be preventable. Recommendations on regulation and enforcement, disaster preparedness, search and rescue, and medical response are discussed.

OBJECTIVES: To examine the serum levels of degraded monosaccharides in children with Henoch-Schönlein purpura (HSP) and to study the clinical significance of degraded monosaccharides in HSP. METHODS: A prospective analysis was performed on 132 children who were diagnosed with HSP from September 2019 to January 2022, and 132 healthy children were enrolled as the control group. High-performance liquid chromatography was used to determine the content of degraded monosaccharides in serum in both groups. The receiver operating characteristic (ROC) curve was used to evaluate the efficiency of degraded monosaccharides for the diagnosis of HSP. RESULTS: Compared with the control group, the HSP group had significantly higher serum levels of mannose, glucosamine, aminogalactose, and galactose (P<0.001). The four degraded monosaccharides had an area under the ROC curve of 0.919, 0.913, 0.832, and 0.932 respectively for the diagnosis of HSP (P<0.05). CONCLUSIONS Children with HSP have higher serum levels of mannose, glucosamine, aminogalactose, and galactose than the healthy population. The levels of degraded monosaccharides may have an important value for the diagnosis of HSP.

This study was done to analyze the consumption patterns of health functional food (HFF) as well as to perform needs assessment for the development of web-contents on HFF according to age of adults. The subjects were 238 male and female adults, divided into 4 groups by their age. This study collected all information by self-administrated questionnaires. The awareness on HFF was high in the older adults. The younger adults showed more negative responses to reliability and safety on HFF. The main reason for the consumption of HFF was to supplement nutrients and to prevent diseases. The main types of HFF consumed by adults were nutritional supplementary food, red ginseng products, and glucosamine products. There was higher consumption of nutritional supplementary food in the younger adults and glucosamine products in the older adults. Internet users had low level of satisfaction, with tendency to complain poor contents, reliability, difficulties in searching as problems of the pre-existing HFF websites. As useful methods for provision of information on HFF, most adults wanted general information, articles written by experts and videos. They also wanted to know the safety and side effects of HFF. Requirement of contents composition were various in-depth information, clear indication of citation, fresh updated data while that of display composition was easily-findable, uncomplicated, allowing mutual exchange of communication through bulletin board. These results can be used as basic data that reflect the consumer's needs for developing HFF web-contents according to age of adults.

PURPOSE: Poly-N-acetyl glucosamine(PGlcNAc) nanofiber-based materials, produced by a marine microalga, have been characterized as effective hemostatic and angiogenic agents. The similarity between PGlcNAc patch and the natural extracellular matrix allows it to support new healthy tissue growth in an injured area and to encourage fluid absorption. In this study, we hypothesized that a poly-N-acetyl glucosamine fiber patch(PGlcNAc patch) may enhance wound healing in the db/db mouse. METHODS: PGlcNAc patches were applied on one square centimeter, full-thickness, skin wounds in the db/db mouse model. Wounds(n=15 per group) were dressed with a PGlcNAc nanofiber patch for 1 hour(1h), 24 hours(24h) or left untreated(NT). After the application time, patches were removed and wounds were allowed to heal spontaneously. The rate of wound closure was evaluated by digital analysis of unclosed wound area in course of time. At day 10, wounds(n=7 per group) were harvested and quantified with immunohistochemical markers of proliferation(Ki-67) and vascularization (platelet endothelial cell adhesion molecule, PECAM-1). RESULTS: Wounds dressed with PGlcNAc patches for 1 hour closed faster than control wounds, reaching 90% closure in 16.6 days, nine days faster than untreated wounds. Granulation tissue showed higher levels of proliferation and vascularization following 1h treatment than the 24h and NT groups. In addition to its hemostatic properties, the PGlcNAc material also appears to accelerate wound closure in healing-impaired genetically diabetic mice. CONCLUSION: This material, with its combination of hemostatic and wound healing properties, has the potential to be effective agent for the treatment of complicated wounds.

BACKGROUND/AIMS: Glucosamine is widely taken as a functional food, and some studies reported its anti-inflammatory effects. K+ channels and intracellular signal play important roles in the activation of immune cells such as T lymphocytes. Therefore we aimed to examine the effects of glucosamine on the cell physiological parameters. METHODS: In Jurkat-T lymphocytes, intracellular [Ca2+] ([Ca2+]i) was measured using fura-2 fluorimetry, and voltage-gated K+ current (I(Kv)) was measured using whole-cell clamp technique. Ca2+-activated K+ current (I(Kca)) was measured in HEK293 cells over expressing SK4 using inside-out patch clamp technique. RESULTS: An acute application of glucosamine (0.5 mM) affected neither the increase in [Ca2+]i induced by CD3 stimulation (anti-CD3 Ab, 5 microgram/mL) nor the I(Kv) in Jurkat-T cells. A chronic stimulation of with anti-CD3 Ab (5 microgram/mL, 24~36 hr) largely increased the amplitude of IKv. However, the combined treatment with glucosamine (0.1 mM) did not block the increase of I(Kv). The I(KCa) in SK4-overexpressing cells was slightly decreased by glucosamine (0.5 mM). CONCLUSIONS: While glucosamine had a minor inhibitory effect on SK4 K+ channels, the anti-inflammatory effects of glucosamine could not be explained by the effects on the Ca2+ signaling in T lymphocytes.
