If improvement, continue for at least 12-24 months after the remission of symptoms in older adults. If there is a history of previous recurrent depression, consider treatment indefinitely. Bone is a living organ, tissue mostly made up of collagen that has been mineralized with calcium phosphate, which provides strength and hardness to the skeleton. Osteoporosis may be primary (a combinational of post-menopasual loss of estrogen in females, and/or related to aging losses of osteoblasts seen in both men and women) or secondary to some other disorder (such as osteomalacia, hyperparathyroidism, hyperthyroidism, glucocorticoid excess, renal failure, liver disease, etc. Because of its higher turn over, the imbalance of osteoclast activity (especially in the absence of estrogen) leads it to become progressively demineralized and osteoporotic. Even though there are aging associated changes in the bladder and the urinary tract which make the elderly person more prone to urinary incontinence, the problem is not and should not be considered as part of ageing. With urination, sympathetic and somatic tone decreases, and parasympathetic impulses causes the bladder to contract allowing voiding to take place. P polyuria, pharmaceuticals Causes of Persistent Urinary Incontinence: Stress: Involuntary loss of urine (usually small amounts) with increase in intraabdominal pressure. Urge: Leakage b/c of inability to delay voiding after sensation of bladder fullness is perceived. Overflow: Leakage (small amounts) resulting from mechanical forces on an over distended bladder or from other effects of urinary retention on bladder and sphincter function. Depending on the acuteness of the decline, admission to a medical ward or a Geriatric Assessment Unit is recommended for the initial assessment. A 1990 national telephone survey of 2,000 seniors showed that up to 4% of Canadians over the age of 65 may be abused or neglected. A recent study of 31 Canadian nursing homes found that 36% of nursing home staff had witnessed the physical abuse of an older adult in the preceding year and that 81% had witnessed psychological abuse. A 1988 Health and Welfare Canada study found that financial abuse accounted for over 50% of the documented cases of elder abuse. Many believe that laws intended for the general public are adequate for cases of abuse of older adults, with some of the behaviors performed by the abuser can lead to charges of criminal offense. Begin with open ended questions about, then zero in on direct questions about possible maltreatreatment and abuse. Sensitively enquire about stressors they are undergoing in the performance of their role, and ask what they understand about the medical problems of the older adult in their charge. Ask how many hours they are involved in their care giving role, and if they are getting supports from anyone. If abuse is denied, rigorously document your reasons for abuse (physical signs such as burn marks, rope marks, bruising). Falls in the elderly are also the leading cause of injury admissions to Ontario acute care hospitals. Each time observe if they demonstrate nystagmus or a replication of their dizzy symptoms (see picture). Unnecessary prescribing, misuse of medication and inappropriate prescriptions can contribute to the risk of drug-related illness and result in unwarranted costs in health care delivery. Previously defined as 5 or more new drugs during a given 3 month period, it is estimated that 15% of patients are at risk of from polypharmacy. A more current term is Medication Optimization (since many patients truly need the many medications for their plethora of problems), and the thinking has now shifted from simply reducing medications, to ensuring than an older person be on the optimum number and dose of medication for their problems. Medications that may have been relatively benign when the patient was younger, can accumulate risks as the person ages (and with that, changes in drug metabolism and pharmacokinetics). The main concern in the elderly is that side effects should not outweigh beneficial effects. Other safer asthma medications are available * Note: these agents may be acceptable in some instances. Defining inappropriate practices in prescribing for elderly people: a national consensus panel. Medical treatment, management of property and personal care are areas where capacity assessment is often necessary. There are many dilemmas and ethical questions surrounding matters of competency and capacity. Formal assessors can be available (for a steep fee) to help make this determination, and they can be arranged via the Capacity Assessment Office of the Ontario Ministry of the Attorney General. The analogy is that of a person living in a condemned house: if they know that the place may fall about their head any moment, while we may not agree with their living situation, we must abide by it. In contrast, if one is living in a condemned house but denies that there is anything wrong with such an unsafe living arrangement and denies that they may come to harm, in this instance they are not capable of understanding the risks of their current situation and are therefore not capable of making such living decisions on their own. Take it in your right hand, use both hands to fold it in half, and then put it on the floor. If a person is blind, cannot read or write, or has aphasia, note their deficits and provide scores out of this new denominator. While there are 4 point scales and 30 point scales in circulation, there is no advantage in having more questions asked than on the 15 item version below (Pomeroy et al, Int J.

The use of ultraviolet light for surface disinfection within research facilities has started to increase as well due to its ease of use, short dosage times, and broad efficacy. This radiation is very close to the peak of the germicidal effectiveness curve of 265nm, the most lethal wavelength to microorganisms. The process is environmentally friendly in that there are no dangerous or toxic chemicals that require specialized storage or handling. Since no chemicals are added to the air/water, there are no process byproducts to be concerned with. Disinfection times are fast, with a typical disinfection cycle lasting about 15 minutes. This allows for extremely fast turnover times for rooms or other spaces being disinfected. All surfaces within a certain distance will observe an assured level of disinfection in a certain amount of time as long as the light is not blocked from shining on that surface. Surfaces can be blocked from the light if objects are in the way, much like a beach umbrella offering protection from the sun. It has long been available for biological safety cabinet disinfection and home water treatment as well. It provides a chemical free method of disinfecting soundproofing materials that are traditionally chemically incompatible. The units "J/m2" are used in most parts of the world except for North America, where "mJ/cm2" are used. A two log reduction is a 99% reduction of organisms, followed by a three log reduction (99.

These parasites are generally not susceptible the word "parasites" conjures up images of gross to antibiotics that kill bacteria but there are effective looking tapeworms, roundworms, and fleas, or of drugs to treat some (not all) parasitic infections. Many have been considered problems con fined to tropical countries and places with poor What foods have the potential for sanitation and therefore of little concern to the U. However, recent outbreaks of parasitic diseases have demonstrated the inaccuracy of these assumptions. Parasites of concern to food safety professionals Not all parasites live only in the tropics [as witness include several worms, ranging from a few centime the Milwaukee Cryptosporidium outbreak (179)], and ters to several meters in length, and protozoa, single consumers in the U. Many parasitic that originate in the tropics because of increasing infections are asymptomatic, others cause acute short international travel [Angiostrongylus in tourists re lived effects, and still others may persist in the body turning from Jamaica (252)] and globalization of food causing chronic effects (195). Finally, some of the most important parasites Protozoa are neither tapeworms, insects, nor blood-borne. Protozoan parasites may be present in freshwater Parasites are organisms that obtain their food from sources that have been contaminated with human or other living creatures. Usually parasites are smaller than their food is sometimes present in raw meat, particularly pork, source and this distinguishes them from predators and thorough cooking is needed to destroy it. Different life cycles will be described in a (cyst or oocyst) which can withstand some drying later section. It has been estimated that humans harbor about 300 species of parasitic worms and over 70 species Foodborne parasitic worms of protozoa (27;51;212). Many of these have co Cestodes (tapeworms): Meat and fish may contain existed with us for thousands of years and have been larval tapeworms that can develop into adults in the identified among human remains by archaeologists human intestine. Not all parasites are foodborne and some are be present on fruits or vegetables fertilized with very rare. The worms and travel to the muscles, brain, and other parts of include tapeworms (cestodes), flukes (trematodes) the body where they encyst and may cause serious and roundworms (nematodes). Gnathostoma, and Anisakis, exist as cysts in muscles of meat or fish and may (Trichinella) or may not In the U. Angiostrongylus underdeveloped parts of the world, and viruses and utilizes two intermediate hosts and may be present in bacteria are more frequent causes of foodborne snails and on leafy vegetables. However, parasites are becoming more of a concern for the following reasons: Trematodes (flatworms or flukes) usually have two or more intermediate hosts. Some may be present Increasing imports of fruits, vegetables, and ethnic on aquatic vegetables or foods washed in contami foods, some of which originate in countries nated water (Fasciola and Fasciolopsis) while others without modern sanitary facilities and inspection encyst in fish (Clonorchis) or crabs and wild boar systems, may introduce parasites.

Below is a brief summary of such as sushi and raw pork sausages, may increase methods which have been investigated, and Table 3 exposure to parasites. Sanitation and Hygiene Although parasitic infections may not be very Proper disposal of human and animal wastes to frequent in the U. Composting of this material An interesting issue being considered by some could kill parasite eggs. Some Control of flies, cockroaches, and other insects diseases are presently confined to tropical may prevent dispersal of infective stages of and subtropical areas because cysts or intermediate parasites to foods. But if lake temperatures Thorough washing of raw vegetables and fruits warm up and winter temperatures moderate, may remove cysts, oocysts, and eggs of parasites, some diseases may encroach on temperate areas but it is difficult to adequately clean some leafy (7). Low pH and low water activity Infected animals may be treated with drugs to kill combine to kill parasites so that less acidic products parasites, and vaccines are being developed to may require an aw<0. These systems ensure that nearly All infective stages of parasites are destroyed by all meat reaching consumers in the U. For food to be eaten raw, such as fish and some Ultraviolet light can disinfect water containing meats, freezing for several days can inactivate or kill Giardia cysts. Some other parasitic worms require longer Life Cycle Targets or shorter periods at freezing temperatures.

Infective trichinae have been found in polar worms that are producing eggs and thereby reduce bear and grizzly bear meat frozen for 24 months the incidence of cysticercosis. Parasites spend some time in the environment as Filtration and Chlorination and Other Disinfectants cysts or eggs but these are resistant to desiccation Filtration systems can remove protozoan cysts and other stresses. However, several survive in running water for as long as 122 days and outbreaks of cryptosporidiosis associated with in pasture for up to a year, and Giardia cysts can surface water that had been filtered indicate that survive for months in cold water.

Viral proteins are synthesized as part of a polyprotein that is co and post-translationally cleaved by viral and cellular proteases. The structural proteins are contained in the N-terminal portion of this polyprotein and the non-structural proteins in the remainder. Virion assembly, including acquisition of a glycoprotein-containing lipid envelope, occurs by budding through intra cellular membranes. Viral particles are transported in cytoplasmic vesicles through the secretory pathway before they are released by exocytosis, as shown for members of the genus and assumed for members of the other genera. The genera are antigenically unrelated, but serological cross-reactivity exists among members within each genus. The biological properties of the three genera exhibit different characteristics and are described in the corresponding sections. Type species the 5 end of the genome possesses a type I cap (m7GpppAmp) not seen in the other genera. Most faviviruses are transmitted to vertebrate hosts by arthropod vectors, mosquitoes or ticks, in which they actively replicate. Some faviviruses are zoonotic agents transmitted between rodents or bats without known arthropod vectors. Intracellular immature virions contain the precursor prM instead of M, which is proteolytically cleaved during maturation. In certain instances, partially mature/immature forms are also released from infected cells. It is a dimeric, rod-shaped molecule that is oriented parallel to the membrane and does not form spike-like projections in its neutral pH conformation. Image reconstructions from cryo-electron micrographs (Figure 1) have shown that the virion envelope has icosahedral sym metry, in which E protein dimers are organized in a herringbone-like arrangement. Virions contain three structural proteins: C (11 kDa), E (50 kDa), the major envelope protein, and either prM (26 kDa), in immature virions, or M (8 kDa), in mature virions. The E protein is the viral hemagglutinin, which mediates both receptor binding and acid pH-dependent fusion activity after uptake by receptor-mediated endocytosis. It is a multifunctional protein that acts as the viral RdRp and also possesses methyltransferase activity involved in the modifcation of the viral cap structure. Virions contain about 17% lipid by weight; lipids are derived from host cell membranes. Virions contain about 9% carbohydrate by weight (glycolipids, glycoproteins); their composition and structure are dependent on the host cell (vertebrate or arthropod). Virus particles can frst be observed in the rough endoplasmic reticulum, which is believed to be the site of virus assembly. These imma ture virions are then transported through the membrane systems of the host secretory pathway to the cell surface where exocytosis occurs. Shortly before virion release, the prM protein is cleaved by Flavivirus genome organization (not to scale) and polyprotein processing. Boxes below the genome indicate viral proteins generated by the proteolytic processing cascade. Flavivirus-infected cells also release a noninfectious subviral particle that has a lower sedimentation coeffcient than whole virus (70S vs. The envelope protein E is the major target for neutralizing antibodies and induces protective immunity. Antigenic sites involved in neutraliza tion have been mapped to each of the three structural domains of the E protein. Antibodies to prM can also mediate immunity, probably by neutralizing viruses with partially uncleaved prM. Flaviviruses can infect a variety of vertebrate species and in many cases arthropods. Arthropods are usually infected when they feed on a ver tebrate host during viremia, but non-viremic transmission has also been described for tick-borne faviviruses. A new group of faviviruses that appear only to infect mosquitoes is now recognized. The prototype of these faviviruses was tentatively assigned to the genus following the discovery of cell fusing agent virus. However, several genetically related but distinct insect-only faviviruses have now been identifed and will need to be considered as a possible separate group of viruses within the genus. Most faviviruses are arthropod-borne viruses that are maintained in nature by transmission from hematophagous arthropod vectors to vertebrate hosts. About 50% of known faviviruses are mos quito-borne, 28% are tick-borne and the rest are zoonotic agents transmitted between rodents or bats without known arthropod vectors. In certain instances, faviviruses can be transmitted to humans by blood prod ucts, organ transplantation, non-pasteurized milk or aerosols. In the arthropod vectors, the viruses may also be passed on trans-ovarially or vertically (mosquitoes, ticks) and trans-stadially (ticks). The mechanisms of virus transmission involving the insect-only faviviruses may include vertical transmission but other mechanisms need to be considered to explain the success with which these viruses appear to have dispersed globally. Flaviviruses have a world-wide distribution but individual species are restricted to specifc endemic or epidemic areas. More than 50% of known faviviruses have been associated with human disease, including the most important human pathogens: yellow fever virus, dengue virus, Japanese encephalitis virus, West Nile virus and tick-borne encephalitis virus. Flavivirus-induced diseases may be associated with symptoms of the central nervous system. Several faviviruses are pathogenic for domestic or wild animals (turkey, pig, horse, sheep, dog, grouse, muskrat) and cause economically important diseases. Species demarcation criteria in the genus include: Nucleotide and deduced amino acid sequence data. While nucleotide sequence relatedness and the resulting phylogenies are important criteria for species demarcation, the other listed criteria may be particularly useful in demarcation of genetically closely related viruses. These viruses are also antigenically distinguishable in neutralization tests that employ convalescent sera. On the other hand (like poliovirus with its three serotypes), the four dengue virus serotypes com prise a single species, despite being phylogenetically and antigenically quite distinct. This is justi fed by the fact that they co-circulate in the same geographical areas and ecological habitats, and that they exploit identical vectors, exhibit similar life cycles and disease manifestations. Two biotypes of pestiviruses, cytopathogenic (cp) and non-cytopathogenic (noncp) viruses, are distinguished by their ability to cause cytopathic effects in cell culture. Negative contrast electron micrograph of particles of an isolate of bovine viral diarrhea virus 1. Finally, cp viruses may also arise by deletion of large portions of their genomes. Virions are composed of four structural proteins: a basic nucleocapsid core protein, C (14 kDa) and three envelope glycoproteins, Erns (gp44/48), E1 (gp33) and E2 (gp55). All three glycoproteins exist as intermolecular disulfde-linked complexes: Erns homodimers, E1-E2 heterodimers and E2 homodimers. Npro is a proteinase that auto-catalytically releases itself from the nascent poly protein. The proteases and proteolytic steps involved in the generation of individual proteins are indicated. Pestivirus replication is initiated by receptor-mediated endocytosis involving most likely more than one cell surface molecule and viral glycoproteins Erns and E2. Polyprotein processing occurs co and post-translationally by both cellular and viral proteases. Downstream cleavages that produce structural proteins C, Erns, E1 and E2 as well as p7 are mediated by cellu lar signal peptide peptidase and signal peptidase(s). Glycoprotein translocation to the endoplas mic reticulum occurs by an internal signal sequence, within the C-terminal region of the C protein. Cleavage between E2 and p7 is not complete, leading to two intracellular forms of E2 with different C-termini. However, viral proteins are not found on the cell surface, suggesting that viruses mature in intracellular vesicles and are released by exocytosis. Pestiviruses are antigenically related, and cross-reactive epitopes are found for all members. Separate antigenic determinants defned by monoclonal antibodies (Mabs) have also been iden tifed. Mab binding patterns are generally consistent with the genetic relatedness of viruses. Pestiviruses infect pigs and ruminants, including cattle, sheep, goats and wild ruminants. Pestivirus infections may be subclinical or produce a range of clinical conditions including acute diarrhea, acute hemorrhagic syndrome, acute fatal disease, and a wasting disease. Transplacental infection can result in fetal death, congenital abnormalities, or lifelong persistent infection. Fatal mucosal disease can occur in cattle persistently infected with noncp viruses when a cp virus is gen erated by mutation or introduced by superinfection. Experimental infection models have not been established for bovine or ovine pestiviruses out side their natural mammalian hosts. Cells derived from natural host species (bovine, porcine, ovine) support virus replication. Most virus iso lates are noncp and can establish persistent infections in cell culture. Cp pestiviruses induce extensive cytopathol ogy and form virus plaques under appropriate conditions. Species demarcation criteria in the genus include: Nucleotide and deduced amino acid sequence relatedness. Nucleotide sequence relatedness is an important criterion for pestivirus species demar cation. However, in some cases the nt sequence relatedness may be ambiguous and must be complemented with additional comparative analyses. Finally, differences in host of origin and disease can assist in species identifcation. In addition, the genotypes of these species can be further divided into subgroups. In order to offcially establish a novel pestivirus species or genotype, the complete genomic sequence of at least one virus isolate together with data on antigenic relatedness should be provided. Virions are about 50 nm in diameter, as determined by fltration and electron microscopy. They are spherical in shape and contain a lipid envelope, as determined by electron microscopy and inacti vation by chloroform. An additional protein, p7 (believed to have prop erties of an ion channel protein important in viral assembly) is incompletely cleaved from a precur sor of E2 to yield E2-p7 and p7, but it is not known whether these are virion structural components. The two envelope glycoproteins can associate as non-covalent heterodimers; recent data, however, indicate that they are covalently linked complexes in virions. Historically, based on observed removal of the viral enve lope and loss of infectivity following exposure to solvents or detergents, the presence of lipids was inferred. Recently, it has become apparent that the host lipid metabolism plays a critical role in the viral life cycle. They are apparently masked when budding occurs allowing the virion to move through the secretory pathway. Recent data in culture systems indi cate that N-linked glycans of E1 remain in the high-mannose chains lacking complex carbohydrate, whereas those of E2 are modifed. Hepacivirus genome Hepacivirus genome organization (not to scale) and polyprotein processing. The host and viral proteases involved in cleav age of the polyprotein are indicated. The cleavage by host signal peptide peptidase (at the C-terminus of core) is indicated by an open arrow; the cleavages by host signal peptidase (remaining sites) are indicated by flled arrows. Replication is poorly understood but occurs in association with intracyto plasmic membranes. Translocation of the structural glycoproteins to the endoplas mic reticulum probably occurs via internal signal sequences. Cleavage of the structural proteins is mediated by host cell signal peptidases, and signal peptide peptidase. Virus assembly is believed to occur by budding into vesicles from the endoplasmic reticulum. Both linear and conformational epitopes are believed to be involved in the humoral immune response of the host to infection. Hepatitis C virus is transmitted almost exclusively by parenteral exposure to blood, blood prod ucts and objects contaminated with blood. Sexual and mother-to-child trans mission has been documented, but are relatively uncommon. Infections range from subclinical to acute and chronic hepatitis, liver cirrhosis and hepatocellular carcinoma.

Oximeter the finger oximeter records pulse and oxygen saturation using a small light that shines through the finger. Colored nail polish defeats the function of the oximeter, and must be removed from the finger prior to sensor attachment. There are 2 types of oximeter sensors for use, depending on preference and participant comfort: Flexi-Fit (8000J): 1. Place probe onto the Flexi-wrap sensor holder following the guide holes and illustration. Place the finger into the sensor nail-side up with the tip of the centerline mark in the curved area. Close the Vest After the electrodes and sensors have been securely attached to the participant the wires should be straightened and closed into the side flaps. If there is any slack on the electrodes they may be bundled together at the back of the head and secured with a posey wrap. The bib of the vest should be closed and snapped but he recorder must remain unattached to the participant and freely available to the technician at this point. The recorder will be attached to the abdominal respiratory belt after the sensor activations have been performed. Insert the flash card into the slot with the top side of the flashcard faces the front of the recorder. Turn the Somte on by holding down the small orange power button (left) until the amber status light begins to flash. To clear the error message and restart the internal testing power the unit off, and then back on. Check Impedances Once on the idle status screen if any of the head sensors have impedance greater than 5 k they will be displayed. Attach the recorder to the abdominal belt by undoing the belt and passing it through the slot on the back of the recorder. Instruct the Participant Instructions should be given regarding how to move with the equipment in place and what to do if a sensor comes loose. The cannula and thermistor and finger oximeter are important sensors so if the participant removes any of these in order to eat, blow the nose or wash the hands they should be instructed how to replace the sensor with a return demonstration. A complete list of instructions should be reviewed with and then left with the participant. Instruct the participant that the recorder will being recording automatically before his usual bedtime and the flashing amber light will change to flashing green. No action is needed unless the cannula needs to be removed before eating or drinking. Also instruct the participant on how to remove the sensors, equipment and vest in the morning, unless there is a plan to have clinic staff assist with the removal. The cannula is disposable but the thermistor requires high level disinfection upon return to the clinic. Departure All items used for the hook-up should be wrapped in the protective under pad and disposed in the trash can. The Next Morning Accepting the Equipment At return of the sleep equipment the flash card should be removed for downloading. Gloves should be worn when handling the recorder and its components while preparing to clean and throughout the cleaning process. The gold disk electrodes and thermistor must undergo high level disinfection after each use, and all other items must be sanitized. After this process is completed you can close Data Card Manager and Click on the Profusion 3 icon on your computer desktop and open the study. The study is now ready for you to review quickly before sending to the Reading Center. The study must be manually opened in review software (Profusion3) after download is completed. Re-Format the Flash Card the flash card should only be reformatted after the download has been successful and the study has been reviewed. Access My Computer from either a desktop shortcut or the Microsoft Start button (lower left corner of computer screen). In order to be sure you have the correct drive you may wish to open it and check the files. When you are satisfied the correct drive has been chosen select the drive to highlight it and right click. Attendance at Central Training conducted by the Reading Center or one-to-one training from someone in attendance at Central Training. If trained at site, the On-Site Training Check Sheet must be completed by the instructor and submitted to the Reading Center. The evaluator must be a member of the training staff or a certified tech that attended Central Training. One of these practice recordings can be done during Central Training, and the others should be done in a home setting. This serves both as part of the tech certification and as practical experience in using the equipment in the study environment. Certification studies also allow for verification that all sensors and equipment are functioning properly before being used on a study participant. If participant scheduling or vacations prevent this, a limited hook up on a volunteer can substitute for a full recording. The Reading Center will give quality grades for each recording and report the average grade. All requirements for certification must be submitted to the Reading Center via ftp server transmission. Setting Up Data Card Manager Several Options need to be set in Data Card Manager before using. Use the Help Button to access a complete instruction manual for using Study Manager. If you are unable to download contact the Sleep Reading Center before reformatting the flash card. During the download process certain files are created by the Compumedics software that are needed for viewing the study. The time it takes to complete the conversion depends upon the length of the study. Renaming the File Folder containing the Sleep Study At the time of download the Compumedics program automatically names the folder with a very lengthy key which consists of the date of the recording followed by a large group of random numbers. If you have downloaded several studies and are unsure of which participant is in the directory use Profusion Study Manager to identify the correct study. If you need to select another directory where your studies are located, then select the button to access the directory listing on your computer. The epoch number, time of recording, and sleep stage (after scoring) are displayed at the top of the page in the center. Include any notes or comments regarding your review and any troubleshooting procedures done. Profusion Study Manager Profusion study Manager is another tool that will allow you to open a study for review. Do not delete studies until you have received final reports from the Reading Center. Profusion Study Manager is a useful tool if you have downloaded several studies and not had time to rename the folders properly. It will display the name of the folder and that will help you identify which participant sleep study is in that folder so it can be properly named. Transfer of Data to the Sleep Reading Center Data should be sent to the Sleep Reading Center on a weekly basis. This will enable the Sleep Reading Center to evaluate the signal quality and equipment functioning in a timely manner. After successful download the Sleep Study folder containing the sleep files will need to be named appropriately. Be sure the folder containing the sleep study has been properly named before creating the encrypted zip file. Each clinical site will receive a designated username and password that will be used for data upload. Each project will have a separate zip password that will be used for encrypting data files and this will also be sent to the site Project Coordinator. After installation of FileZilla, click on the FileZilla icon to display the main screen. Once a new site is set up and appropriate information is filled in it can be used to connect whenever needed. Preparation of Data for Upload In order to both ensure data security and integrity, and to make transfers more efficient, all data that is sent to the Sleep Reading Center must be prepared as follows: Deidentification all files sent to the reading center must be devoid of all personal health identifiers, including participant names, dates of birth, etc. Each file should only contain the participant id and other study information as indicated in the study manual of procedures. This can be accomplished by an additional step when the zip file is created as detailed below. The instructions below are for creating a Zip File using Windows Compressed Folders. If you are using WinZip please follow the instructions provided with that software. Creating and Encrypting Zip File (using Windows Compressed Folders) Locate the files that are to be sent to the reading center. Right-click on the files and select Send To > Compressed (zipped) Folder the selected files will be added to the zip file. Open the compressed folder (double-click on the compressed folder, or right-click and select Open With > Compressed (zipped) Folders) Encrypt the files by selecting File > Add a Password Enter the project encryption zip password provided to Study Coordinator (and confirm). Contact If you have questions about uploading files or have difficulty connecting, please contact the Sleep Reading Center Susan Surovec (ssurovec@partners. The Sleep Reading Center requires that one Technician from each site must attend Central Training and complete the initial certification process at Central training. After completion of all required Certification procedures they will be able to observe and certify others at the site. All leads and peripherals used should be labeled and kept with the same unit to enable accurate troubleshooting methods. A Sample of this Summary Report tracking quality by Site/Tech/Unit is displayed on the next page. Data is encrypted, where applicable, in compliance with state and federal government standards, regulations, and in accordance with Partners Security and Privacy policies. All configuration changes that could affect accessibility or security are approved by management. Receipt date will be recorded as the day the study was received in the Incoming folder. If there is a discrepancy between the data contained on the Signal Verification Form and the Somte Sleep Study recorded file or any missing data on the forms. If at time of download of the flashcard there is no data, both of these forms must still be sent. A note should be made on the forms that there was no data on the card at time of download. The problem studies are monitored and if any pattern is observed study wide not related to technician technique we will work to resolve the problem with the vendor. Studies containing less than the minimal requirements will not be processed for scoring and the site coordinator will be notified via e-mail to request a repeat study from the participant. Site will provide alternate staff contacts should personnel normally receiving these notices be unavailable. Potential Urgent Referrals include all cases of atrial fibrillation, regardless of rate, pre-existing diagnosis, or duration or rhythm disturbance. The total duration of the study (from Time to Bed to the lights on) and the total duration of sleep will also be indicated.
