the white coat

so here’s something i’ve been noticing and observing for quite a few years. as many have probably seen, even if you didn’t give it much attention, doctors tend to walk around with their white lab coats pretty much the entire day. yes, that means that if they go for lunch, if the leave the hospital or their practice grounds, they will still wear their white coats. i’m quite unsure as to what the reason is, although one might be willing to venture a guess.

what’s my problem with it? well, let’s see. doctors usually deal with sick patients, on a daily basis they meet, talk and treat various people with a wide range of conditions. so, here’s a simple scenario…doctor treats patient, patient sneezes (remember, simple scenario), reaches the coat, doctor touches it eventually and wears his coat walking into the tim hortons across the street for coffee, bumps in line and other people get in contact with his white and ‘clean’ coat…and some transfer may and probably does occur of whatever was in the sneeze from earlier…

i admit it, it’s a simple scenario and it depends on how well the virus can survive on the coat, the amount, etc…however, doctors come in contact with various patients…essentially, come in contact with various pathogens…which can be transmitted indirectly into the community if the doctors wear their coats outside the appropriate environment. their coats are essentially the first point of contact, not for all doctors but for most of them. so, it’s not very hard to see that if contamination gets on these nice ‘clean’ white coats, the same pathogens can transfer to other places and thus indirectly pose a threat to the public. the risk of indirect transfer of various pathogens is there, if the doctors keep wearing their coats…and walk into public places (i.e. restaurants, coffee shops, markets, etc.).

futhermore, chemical safety for laboratory employees require lab coats to only be worn in the lab. walk into any commercial laboratory and you will not be allowed to wear your labcoat into the lunch room…let alone outsides the company. furthermore, lab coats are not to be taken home, so not to carry various contaminants (regardless of what they are) home and expose yourself and your family. thus, at least in british columbia, lab coats are to be washed by the employee. so, if we’re so keen on making sure some various chemicals don’t get into the lunch room or public places, then i am wondering why doctors get to carry their white coats from inside the hospital to the various places where they go and eat lunch? biological laboratories have similar regulations. so these sort of rules are used.

so, if this risk is there, i wonder and question why these doctors put us all at a potentially higher risk of contamination by not simply taking off their coats prior to leaving their working grounds? regardless of the level of contamination, prevention of a disease is always cheaper and more useful than treatment for it. last i recall, doctors take some oath to help sick people…then again, sick people is the ‘key’ word. so i guess by not taking off their coats while entering public areas, they’re just trying to make sure they keep having a job in this ‘crisis’ struck economy.

research projects

i’m in my second year of my occupational hygiene masters program. to complete it, essentially i’ll have to submit a thesis based on a few projects i’ve been working on for the past year and a half. the projects are related and revolve around antineoplastic agents or drugs (also referred to as cytotoxic or chemotherapy drugs). their main use, and the most known use for many, is that they are used to treat various types of cancers.

these drugs vary in their mode of actions and the types of cancers they are used to fight. generally speaking, and simplifying matters, their purpose or intent is to destroy cells (in other words, kill cells). the intended cells are usually the one rapidly multiplying, however they are not selective. some of the drugs are known to be carcinogenic, other mutagenic, others teratogenic, and so on. they can have various and serious health effects. so what’s the problem? well, if healthy people get exposed to these drugs, the fear is that the drugs will behave the way they are intended to behave. and that is, to destroy various cells, depending on the drug and its mode of action, and thus create some rather serious health effect(s).

my first project, and the one that got my feet fully wet in research, was to look at the potential by-products produced by oxidizing cyclophosphamide (a chemotherapy drug and known carcinogen) with household bleach. this was my first project, and it is the one i started with as soon as i began the program. this project is close to being completed and some of its findings will be presented soon, at a few conference.

my second project is looking to develop a specific cleaning agent for these drugs. various things are currently being used, and the only one designed to clean antineoplastic drugs is a cleaning agent that has household bleach as its prime ingredient (which is great, if you want to decompose the drugs, but as it turns out based on my first project some of the by-products created may be more harmful than the parent drugs itself; also, some drugs do not get oxidized by bleach).

what do i hope to accomplish with these two projects? well, besides getting a diploma from the program, i’m hoping that the results from these projects will be used to create a safer work environment for the workers dealing with these drugs on a regularly and daily basis. so, there you have it…a quick summary of what i do at school all day long…besides drinking large amounts of coffee…

sometimes even grown men cry…

for most canadian hockey fans february 21st (yesterday) was a day when an ex-captain return to take on his old team. the vancouver canucks visited the toronto maple leafs, in the toronto…bringing with them a ‘small’ and ‘insignificant’ figure…by the name of mats sundin. a player that spent 13 years in toronto, and was their captain for the last 10. the implications of this match go a bit more beyond the return of the maple leaf captain…given the canucks also brought with them a guy name wellwood…and the leafs just recently hired the last two vancouver canucks’ gm’s…thus the implications between the two teams can be stretched…

however, to put matters in perspective…last year sundin was asked by the leafs to wave his ‘no-trade’ clause and give the team a chance to pick up some new guys in order to re-build…he refused and then eventually signed with vancouver. all that being said, it caused quite a bit of stir in the city…and he was accused of going for the green (given vancouver offered quite a nice pay-cheque for his ‘autograph’ on the dotted line).

this is not quite that unusual, that a player leaves a team where he’s a fan favorite and moves over to an opponent, or even worst a rival. for short, for some football fans (yes football…not soccer), remember figo’s move from barcelona to real madrid? what about ashley cole’s move from arsenal to cheslea? and ronaldo’s ‘in-direct’ move from barcelona to real madrid (given he first moved from barcelona to inter milan then to real madrid). they all received boos on their return to face their old team.

the anticipation of last night…was significant…sundin had a few interviews to share his views on the move, the game…essentially everything. it’s quite safe to say, the media yet again played this for ever cent. however, was the old captain going to get boo-ed or cheered as he touched the ice? for the ones who watched the game, he did get boo-ed (minor boos that is), but during the commercial break when a video in his honor was shown…the crowed gave their captain a standing ovation…which did bring tears to the ‘small forward’s’ eyes.

so, boo or not boo? a player that refused to ‘help’ the team grab some much needed young guns, only to leave for nothing…and return to eventually score the shoot-out winner? keep in mind, the leafs don’t have anyone wearing a ‘c’ this season. he spend 13 years wearing the team’s jersey…he bleeded countless of times for the team…and he lead them each and every season. i don’t think they could have asked for a more stand up guy…so no, even though he left the way he did…the fans did the honorable thing and gave him a standing ovation, for what is most likely the last time they will see him playing on the air canada place ice. the fans that boo-ed him, should recall the countless times the player lead their team in the playoffs, the countless of times he stood up for the community in toronto…and what he meant to the team each and every game…

from the canucks’ point of view, it’s nice to see how well sundin was received, for the most part, in his return…thus one can only hope that he will play with the same fire for his new team…as he did for his ‘only canadian home’ team…
