Malaria infections in crews of Japanese ships.

Plasmodium falciparum malaria is the most dangerous infection for seafarers in West Africa. In December 1998, five cases of this infection occurred among Japanese seafarers in West Africa, two of them died, one on board ship, and another died five days after the admission to the hospital in Reunion island, East Africa. Six other cases of falciparum malaria infection occurred among Japanese seafarers on another ship in December 1999. Three infected persons were admitted to hospitals in Abidjan (Ivory Coast) and Point Noire (Congo). In Japan, over 100 cases of imported malaria were recorded each year during the period from 1990 to 1997, and about 40% of these cases were falciparum infections. It is not known how many of them occurred among seafarers. We estimate that at least 5% of all malaria cases in Japan are seafarers. Measures to protect crews of ships against malaria are discussed.

Outbreaks of gastroenteritis associated with noroviruses on cruise ships--United States, 2002.

During January 1-December 2, 2002, CDC's Vessel Sanitation Program (VSP), which conducts surveillance for acute gastroenteritis (AGE) on cruise ships with foreign itineraries sailing into U.S. ports received reports of 21 outbreaks of AGE on 17 cruise ships. Of the 21 outbreaks, nine were confirmed by laboratory analysis of stool specimens from affected persons to be associated with noroviruses, three were attributable to bacterial agents, and nine were of unknown etiology. Seven outbreaks were reported in 2001, and of these, four were confirmed to be associated with norovirus (CDC, unpublished data, 2002). This report describes five of the norovirus outbreaks that occurred during July 1-December 2, 2002, on cruise ships.

Tuberculosis outbreak investigation of a U.S. Navy amphibious ship crew and the Marine expeditionary unit aboard, 1998.

A Marine deployed aboard a U.S. Navy amphibious ship had smear-positive, cavitary pulmonary tuberculosis (TB). Contact investigation ultimately found 21 active cases of TB among sailors and Marines who were aboard the affected ship. Approximately 3 months lapsed between onset of the source patient's illness and appropriate diagnosis and treatment. During the contact investigation, 3,338 persons received tuberculin skin tests and 712 were identified as new latent tuberculosis infection cases. Four persons diagnosed with latent tuberculosis infection developed active TB because of poor compliance with treatment. After personnel disembarked from the ship, persistent efforts to identify persons with active disease and latent infections were successful in controlling further spread of tuberculosis in military units and local communities. The Mycobacterium tuberculosis bacteria isolated from the source patient and 16 of the other active cases were susceptible to all drugs commonly used to treat TB.

Primary Casualty Reception Ship: the hospital within--Operation Granby.

As the build-up of Operation Granby forces developed in the Gulf, casualty estimates indicated the need for a 100-bed hospital facility to care for the possible maritime casualties. RFA Argus, the Air Training Ship, was identified as the potential Primary Casualty Reception Ship (PCRS) and at the end of September 1990 plans were drawn up to convert the forward hangar into a two-storey 100-bed hospital in collective protection (COLPRO). In the three weeks prior to deployment, the hospital was designed, built, equipped and staffed. Argus arrived in the Gulf in mid-November as the PCRS with, all in COLPRO, a 10-bed intensive care unit (ICU), a 14-bed high dependency unit (HDU), a 76-bed low dependency unit (LDU) plus four operating tables in two theatres with full support services. The hospital was staffed by a medical team of 136 personnel and supported by the Air department with four casualty evacuation helicopters, an RN Party and the staff of the RFA. One hundred and five patients were treated of which 78 were returned to duty. Argu as PCRS spent longer in the northern Persian Gulf than any other ship, UK or US.

A burn mass casualty event due to boiler room explosion on a cruise ship: preparedness and outcomes.

The purpose of this study was to review our experience with a mass casualty incident resulting from a boiler room steam explosion aboard a cruise ship. Experience with major, moderate, and minor burns, steam inhalation, mass casualty response systems, and psychological sequelae will be discussed. Fifteen cruise ship employees were brought to the burn center after a boiler room explosion on a cruise ship. Eleven were triaged to the trauma resuscitation area and four to the surgical emergency room. Seven patients were intubated for respiratory distress or airway protection. Six patients had >80 per cent burns with steam inhalation, and all of these died. One of the 6 patients had 99 per cent burns with steam inhalation and died after withdrawal of support within the first several hours. All patients with major burns required escharotomy on arrival to trauma resuscitation. One patient died in the operating room, despite decompression by laparotomy for abdominal compartment syndrome and pericardiotomy via thoracotomy for cardiac tamponade. Four patients required crystalloid, 20,000 mls/m2-27,000 ml/m2 body surface area (BSA) in the first 48 hours to maintain blood pressure and urine output. Three of these four patients subsequently developed abdominal compartment syndrome and died in the first few days. The fourth patient of this group died after 26 days due to sepsis. Five patients had 13-20 per cent bums and four patients had less than 10 per cent burns. Two of the patients with 20 per cent burns developed edema of the vocal cords with mild hoarseness. They improved and recovered without intubation. The facility was prepared for the mass casualty event; having just completed a mass casualty drill several days earlier. Twenty-six beds were made available in 50 minutes for anticipated casualties. Fifteen physicians reported immediately to the trauma resuscitation area to assist in initial stabilization. The event occurred at shift change; thus, adequate support personnel were instantaneously to hand. Our mass casualty preparation proved useful in managing this event. Most of the patients who survived showed signs of post-traumatic stress syndrome, which was diagnosed and treated by the burn center psychology team. Despite our efforts at treating large burns (>80%) with steam inhalation, mortality was 100 per cent. Fluid requirements far exceeded those predicted by the Parkland (Baxter) formula. Abdominal compartment syndrome proved to be a significant complication of this fluid resuscitation. A coordinated effort by the facility and preparation for mass casualty events are needed to respond to such events.

Cruise-ship--associated Legionnaires disease, November 2003-May 2004.

More than 9.4 million passengers traveled on pleasure cruises departing from North American ports in 2004, an increase of 13% since 2003 and 41% since 2001. Cruise ships typically transport closed populations of thousands of persons, often from diverse parts of the world. Travelers are at risk for becoming ill while on board, most commonly from person-to-person spread of viral gastrointestinal illnesses. Certain environmental organisms, such as Legionella spp., pose a risk to vulnerable passengers. During November 2003-May 2004, eight cases of Legionnaires disease (LD) among persons who had recently traveled on cruise ships were reported to CDC. This report describes these cases to raise clinician awareness of the potential for cruise-ship--associated LD and to emphasize the need for identification and reporting of cases to facilitate investigation.

[Hygienic evaluation of the methods of water conditioning on marine ships].

Results of test stands and of field studies (on marine ships) have shown, that the use of installations for water preparation (IWP), including mineralizers of the wash out type and ozonizers, makes it possible to get water of stable quality independent of the terms of operations of the installations, and also provides the possibility of conditioning of shore water supply and of carrying out disinfection of the ship water supply system. Comparative analysis of the operation of various kinds of IWP on marine ships testifies to the necessity of development of the new types of IWP, which will promote health preservation of crew members having difficult long independent voyages.

[The hygienic assessment of the ozonizer units for the housekeeping water supply of ships].

According to the results of the studies the reason of the worsening of water quality in the ozonizer [correction of ozonating] installations of household water supply of ships is the presence of negative biological processes in the system of household and drinking water in combination with the peculiarities of its operation and reliability of functioning of the ship ozonizer [correction of ozonating] station. New technological designs and automated control methods, maintaining the residual ozone doses in the ship network, are needed to keep the drinking quality of water in the system.

The work of ship's doctors of Polish Ocean Lines.

In 1984, during 201 voyages of cargo ships of Polish Ocean Lines having doctors on board, 30340 medical consultations were given to crew members, in 15506 cases of complaints and diseases. Doctors also consulted injured seafarers 2456 times in cases of injuries, wounds, contusions, broken bones, burns, scalds etc. During these 201 voyages, 33 cases of serious medical conditions were reported among crew members, which required disembarkation and hospital treatment abroad; in this number two cases of myocardial infarction ended fatally. There were also 13 casualties among seamen, which were treated in hospitals in foreign ports; all of them survived. One of the important health problems of seafarers were diseases of teeth, pulp, and periapical tissue. Such cases constituted the majority (66.9%) of all 1868 cases referred for consultation and treatment in foreign ports. Oral diseases prevention among seafarers needed improvement. The working time of doctors on board ship was under-utilized. To a greater extent they should be involved in training seafarers in first aid and primary health care, and in health education activities among seamen, during sea voyages. Materials presented in the paper may be of use in planning efficient and cost-effective health services for crews of ships.

Illicit drugs on ships entering Hong Kong.

From 1974 to 1982 government authorities in Hong Kong seized 672 kilograms of illicit drugs in 721 seizures on board 254 vessels. As those vessels exceeded 250 gross tons, they were not subject to forfeiture under the Dangerous Drugs Ordinance (1935). Thus, an amendment to that Ordinance was adopted and came into force on 15 January 1983. It provides for the imposition of a maximum fine of $HK 5 million on the owners of ships exceeding 250 gross tons if such ships are found to have carried excessive quantities of illicit drugs on two occasions within a period of 18 months. The excessive quantity is defined as 3,000 grams of opium or cannabis and 500 grams of any other dangerous drug. Such ships may be forfeited to the Crown if the financial penalty is not paid.

[A hygienic validation of prospective ways to decrease the amount of solid wastes on board ship].

The most perspective way of reduction of solid waste on board the ship is to modify the system of food supplies. The new system must provide for food which is completely ready for use or contain semi-finished products which need few cookery. The food packings must be easily utilized or recycled. The existing amount of garbage on board the ship will be sorted, pressed, treated by conservants, packed into polyethylene bags, and stocked in special compartments or vacant refrigerated store-rooms. The realization of these proposals will make it possible to reduce the quantity of garbage on board the ship, lower the expenditure of labour and electricity for cookery, reduce the potable water consumption, and diminish the size and the quantity of caboose equipment. It's possible to use electric ovens to heat the food, reduce or exclude the usage of submarine disposable containers, and thus, preserve the ecology of world ocean.

An outbreak of viral gastroenteritis on a cruise ship.

Three hundred and seventy-eight passengers reported gastroenteritis during four cruises in the western Mediterranean on consecutive weeks of 1995. The rate at which cases were reported each day increased on the fourth cruise. The ship's owner commissioned an epidemiological investigation from the PHLS Communicable Disease Surveillance Centre. Cases reported explosive vomiting and diarrhoea, which lasted from 24 hours to five days, and were suggestive of viral gastroenteritis. No food handlers reported illness, but enquiries suggested that some had been ill and treated themselves. No bacterial pathogens were isolated from faecal specimens provided by cases or from water, food, and environmental samples taken from the galley. Small round structured viruses (SRSV) were identified by reverse transcriptase polymerase chain reaction in two faecal specimens and one specimen of vomit from people who became ill during the fourth cruise. SRSV was also identified in one faecal specimen by electron microscopy. Environmental inspection revealed inappropriate food handling, hygiene, and storage. During one 24 hour period no chlorine was detectable in the water. A case control study conducted on the fourth cruise sought details of exposure to various foodstuffs, unbottled water, and various parts of the ship. No significant associations were found between illness and any exposures. The evidence strongly suggested a continuing outbreak of SRSV infection transmitted from person to person. Some passengers remained on board for a second week and could have transmitted their infection to new arrivals. The ship was cleared and disinfected at the end of the fourth cruise in order to interrupt transmission. Fewer than 10 cases presented in each of the fifth and sixth cruises.

Semen characteristics after overnight shipping: preservation of sperm concentrations, HspA2 ratios, CK activity, cytoplasmic retention, chromatin maturity, DNA integrity, and sperm shape.

We tested several approaches that can be used to preserve sperm attributes and the objective biochemical markers of sperm maturity and function for assessment in a remote centralized laboratory after overnight shipping of semen samples. Addition of phenyl-methyl-sulfonyl-fluoride (PMSF) to a final concentration of 20 microg/mL semen at 4 degrees C has preserved sperm concentrations and HspA2 isoform ratios, even at room temperature, simulating a shipping delay in moderate ambient temperatures. Regarding the attributes of individual spermatozoa, the patterns of CK-immunocytochemistry (demonstrates cytoplasmic retention in diminished-maturity spermatozoa); aniline blue staining pattern (tests chromatin maturity); sperm shape assessed by both Kruger strict morphology and computer assisted morphometry; and sperm DNA integrity, as tested by DNA nick translation, all remained unchanged. Thus, the PMSF-4 degrees C conditions preserved sperm concentrations and the cytoplasmic and nuclear biomarkers of sperm cellular maturity and function for next-day analysis. This shipping method will facilitate the early detection of subtle changes in semen quality that can affect sperm function, even when there has been no decline in sperm concentrations to signal possible toxic effects. Furthermore, sample preservation will enable investigators to evaluate semen for toxicology studies and for diagnosis of male infertility from remote locations. Home collection of semen should enhance study participation, and semen assessment in centralized laboratories will address concerns regarding interlaboratory variations and quality control.

Flt3 signaling involves tyrosyl-phosphorylation of SHP-2 and SHIP and their association with Grb2 and Shc in Baf3/Flt3 cells.

Flt3 ligand (FL) is an early-acting potent co-stimulatory cytokine that regulates proliferation and differentiation of a number of blood cell lineages. Its receptor Flt3/Flk2 belongs to class III receptor tyrosine kinases that also include the receptors for colony-stimulating factor 1, Steel factor, and platelet-derived growth factor. Using CSF-1 receptor/Flt3 chimeras, two groups have characterized some of the post-receptor signaling events and substrate specificity of murine Flt3 receptor. However, there are few studies on the signaling pathway through human Flt3. We examined human Flt3 signaling pathways in a murine IL-3-dependent hematopoietic cell line Baf3, which stably expresses full-length human Flt3 receptor. This subline proliferates in response to human FL. Like the chimeric murine Flt3, human Flt3 undergoes autophosphorylation, associates with Grb2, and leads to tyrosine phosphorylation of Shc on ligand binding. We found that SHP-2, but not SHP-1, is tyrosine-phosphorylated by FL stimulation. SHP-2 does not associate with Flt3, but binds directly to Grb2. SHIP is also tyrosine-phosphorylated and associates with Shc after FL simulation. We further examined the downstream signaling pathway. FL transiently activates MAP kinase. This activation could be blocked by PD98059, a specific MEK inhibitor. PD98059 also blocked cell proliferation in response to FL. These results demonstrate that SHP-2 and SHIP are important components in the human Flt3 signaling pathway and suggest that SHP-2 and SHIP, by forming complexes with adapter proteins Grb2 and Shc, may modulate MAP kinase activation, which may be necessary for the mitogenic signaling of Flt3.

p85 subunit of PI3 kinase does not bind to human Flt3 receptor, but associates with SHP2, SHIP, and a tyrosine-phosphorylated 100-kDa protein in Flt3 ligand-stimulated hematopoietic cells.

Flt3/Flk2 belongs to class III receptor tyrosine kinases. Like other members of type III receptor tyrosine kinases, murine Flt3 induces tyrosine phosphorylation of p85 and subsequently activation of PI3 kinase upon FL binding. While p85 binds murine Flt3 at Y958 in the carboxyl terminus of the receptor, human Flt3 does not have a potential p85-binding site in the carboxyl terminus. In this study, we examined whether p85 binds to human Flt3 in Baf3/Flt3 and THP-1 cells. In contrast to murine Flt3, p85 is not tyrosine phosphorylated after FL stimulation, nor does it bind Flt3 in both cell lines. Instead p85 associates inducibly with tyrosine phosphorylated SHP-2 and constitutively with SHIP and two tyrosine phosphorylated proteins with molecular weights about 100-kDa (p100) and 120-kDa (p120) in Baf3/Flt3 cells. The p100 associates with both p85 and SHP-2. In THP-1 cells, p85 associates inducibly with tyrosine phosphorylated SHIP, p100 and p120. These results indicate that p85 does not bind human Flt3, but forms a complex with SHP-2, SHIP, p100 and p120 in hematopoietic cells.

Molecular cloning and chromosomal localization in human and mouse of the SH2-containing inositol phosphatase, INPP5D (SHIP). Amgen EST Program.

The action of lipid phosphatases on inositol phosphates is thought to be one method that the cell uses to attenuate growth factor- or cytokine-induced mobilization of calcium. We have cloned a cDNA from a mouse spleen library that is virtually identical to the recently described inositol tetraphosphate and phosphatidylinositol 3,4,5-trisphosphate 5-phosphatase, SHIP. Chromosomal localization studies in human and mouse by FISH mapping and interspecies backcrossing in mice have demonstrated that human SHIP is localized to 2q36-q37.1 and that mouse SHIP is localized to 1C5.

Systematic factor optimization for cryopreservation of shipped sperm samples of diploid Pacific Oysters, Crassostrea gigas.

Despite some 26 published reports addressing oyster sperm cryopreservation, systematic factor optimization is lacking, and sperm cryopreservation has not yet found application in aquaculture on a commercial scale. In this study, the effects of cooling rate, single or combined cryoprotectants at various concentrations, equilibration time (exposure to cryoprotectant), straw size, and cooling method were evaluated for protocol optimization of shipped sperm samples from diploid oysters. Evaluation of cooling rates revealed an optimal rate of 5 degrees C/min to -30 degrees C followed by cooling at 45 degrees C/min to -80 degrees C before plunging into liquid nitrogen. Screening of single or combined cryoprotectants at various concentrations suggested that a low concentration (2%) of polyethylene glycol (FW 200) was effective in retaining post-thaw motility and fertilizing capability when combined with permeating cryoprotetcants such as dimethyl sulfoxide (DMSO), methanol (MeOH), and propylene glycol (P-glycol). However, polyethylene glycol alone was not as effective as MeOH, DMSO, and P-glycol when using the same methods. The highest post-thaw motility (70%) and percent fertilization (98%) were obtained for samples cryopreserved with 6% MeOH. However, this does not exclude other cryoprotectants such as DMSO or P-glycol identified as effective agents in other studies. There was no significant difference in post-thaw motility between straw sizes of 0.25- and 0.5-ml. Equilibration time (exposure to cryoprotectant) of 60 min could be beneficial when the cryoprotectant concentration is low and solution is added in a step-wise fashion at low temperature. Differences in post-thaw sperm quality (e.g., motility or percent fertilization) among individual males were evident in this research. As a consequence, a generalized classification describing males with different tolerances (broad, intermediate, and narrow) to cryopreservation was developed. This classification could be applied to strain or species differences in tolerances to the cryopreservation process. The present study demonstrated that oyster sperm could be collected and shipped chilled to another facility for cryopreservation, and that it could be shipped back to the hatchery for fertilization performed at a production scale yielding live larvae with >90% fertilization. Given the existence of facilities for commercial-scale cryopreservation of dairy bull sperm, the methods developed in the present study for oysters provide a template for the potential commercialization of cryopreserved sperm in aquatic species.
