For example, hypno or body language with which people communicate their sis is considered an altered state of consciousness and feelings; (d) men or women health providers; and (e) ex has been well investigated with studies of functional pressing sexual or other issues. Research studies show that women use high acute, chronic, and cancer-related pain. Tese dierenc er health care services per capita as compared to men es in treatment may arise from the health care system for all types of morbidity and are more likely to report itself (the ability to reach and receive services) or from pain and other symptoms and to express higher distress the interaction between patients and health care provid than men. Furthermore, women in a deprived socioeco ers, as beliefs, expectations, and biases (prejudices) from nomic situation run a higher risk for pain. Patients may be treated by health care providers From the biological point of view, females are who come from a dierent race or ethnic background. Numerous language, or invisible, such as characteristics below the studies have shown that female hormones, and their tip of the cultural iceberg such as attitudes, beliefs, val uctuations across life stages or during the month, play ues, or preferences [2].

It is believed that this greater role makes women ask people with diverse ethnocultural backgrounds, but questions or seek help in an eort to maintain them such knowledge is necessary to improve diagnosis and selves or their family in a good condition. Ethnocultural and environmental factors also account partially for dierences in perceiving and re porting pain or other symptoms. For example, a few What is the eect of gender on studies have shown higher pain perception and expres pain perception and expression and sion in South (Central) Asian groups (including patients health care utilization Altogether, the no physiological dierences when subjects were tested dierences between genders can be attributed to a com for warm and cold perception (this means the level at bination of biological, psychological, and sociocultural which a stimulus was felt as warm or cold). However, factors, such as the family, the workplace, or the groups the South Asians showed lower pain thresholds to heat cultural background in general (summarized by Mailis and were in general more sensitive to pain.

Running head: 2019-nCoV in China Introduction In early December 2019, the first pneumonia cases of unknown origins were identified in Wuhan city, Hubei province, China [1]. Evidence pointing to the person-to-person transmission in hospital and family settings has been accumulating [4-8]. The World Health Organization has recently declared the 2019-nCoV a public health emergency th of international concern [9]. As of February 5, 2020, 24,554 laboratory-confirmed cases have been documented globally. Given the rapid spread of 2019-nCoV, an updated analysis with significantly larger sample sizes by incorporating cases throughout China is urgently warranted.

The league commissioner decides that each team must keep an accurate pitching record of the number of pitches thrown per game 3 antimicrobial agents zithromax 500 mg amex. The community sports medicine physician is also asked to educate coaches and parents about the importance of identifying little league elbow early. The term "Little League elbow" is used to describe a group of pathologic entities in and around the elbow joint in young throwers. The mechanism includes pitching, tennis serving, volleyball spiking/serving, football and javelin throwing. This valgus stress results in lateral compression and medial traction on the elbow. The injury has expanded to include (9): 1) Medial epicondylar fragmentation and avulsion. The physical stresses associated with throwing produce exceptional forces in and about the elbow in the throwing athlete of any age. These forces include tension, compression, and shear localized to the medial, lateral, and posterior aspects of the elbow (10). Compression overload on the lateral articular surface: early and late cocking phases. Posterior medial shear forces on the posterior articular surface: late cocking and follow through phases. A comprehensive history is important and should include age, handedness, activity level, sport played, and history of trauma. The age of the thrower can be helpful in the differential and is divided into three groups: 1) childhood (terminates with appearance of all secondary centers of ossification), 2) adolescence (terminates with fusion of all secondary centers of ossification to their respective long bones), and 3) young adulthood (terminates with completion of all bone growth and achievement of final muscular development) (9). During childhood, pain to the medial epicondyle secondary to microinjuries at the apophysis and ossification center is common. Valgus stress of the elbow results in an avulsion fracture of the entire medial epicondyle. Some athletes develop enough chronic stresses to cause delayed union/malunion of the medial epicondyle. By young adulthood, the medial epicondyle is fused and injuries tend to occur to muscular attachments and ligaments. Also neurological and vascular exams with attention to the ulnar nerve should be performed. Common findings include an immature elbow with elbow enlargement, fragmentation, and beaking or avulsion of the medial epicondyle. Posterior lesions present with hypertrophy of the ulna causing chronic impingements of the olecranon tip into the olecranon fossa. The American Academy of Pediatrics and youth baseball organizations have made recommendations to reduce the risk of overuse elbow injuries in young athletes by providing leagues and coaches with guidelines limiting the number of pitches per day or per game, a young athlete can throw. It is far preferable to prevent these injuries, than it is to recover from these injuries. Playing through such pain worsens the injury, so this practice should be discouraged. A basic strategy to reduce the risk of these injuries is to restrict further elbow throwing stress for the remainder of the day once the onset of pain occurs. If disability continues for an extended period of time, throwing should be disallowed until the next season. Medial epicondylar fractures occur with substantially more acute valgus stresses applied through violent muscle contraction causing an avulsion fracture of the medial epicondyle. This causes a painful elbow with tenderness over the medial epicondyle and elbow flexion contracture that may exceed 15 degrees. When radiographic evidence of union is noted, a specific progressive throwing program is started. Medial ligament rupture to the ulnar collateral ligament is not common in young athletes and is seen more in adults. Patients may have medial tenderness for months to years before the ligament is injured, usually in a sudden catastrophic event. If the injury is detected early, conservative treatment including rest and alternating heat/ice is recommended. It is a self-limiting condition where the capitellum epiphysis essentially assumes a normal appearance as growth progresses. They present with elbow pain and a flexion contracture of greater than or equal to 15 degrees. These patients should be seriously counseled about the dangers of continued throwing and are urged to abstain. Posterior extension and shear injuries are uncommon in young throwers but the incidence increases with age. If there is lack of apophyseal fusion, rest and immobilization can produce good results. Partial avulsion of the olecranon requires surgical reattachment of the olecranon and triceps. They can be seen not just in baseball pitchers but also in quarterbacks, tennis players, volleyball players and javelin throwers. Because the biomechanics of throwing are complex, the physical stresses can cause a group of pathologic entities to include the medial, lateral, and posterior aspects of the elbow. Preventing these types of injuries involves teaching proper throwing mechanics, keeping an accurate pitching count, predetermining a stopping point based on number of pitches thrown, and recognizing early warning signs and stopping once the pain starts. Although many of these injuries have been blamed on throwing curve balls, some studies have shown that a properly thrown curve ball causes no more injuries than the traditional fastball (11,12,13). He was playing in a roller hockey game when a hockey stick was swung high and struck him in the face. Ophthalmology is consulted and further evaluation for the hyphema includes an intraocular pressure measurement, which is found to be normal. The patient and parents are told to limit his activity for the first 72 hours without television or video games. His immunization records are current and the patient is sent home with a narcotic analgesic and follow-up in 3 days. The next season, he is sporting a new pair of safety goggles to every game and practice. Orbital injuries are common injuries in athletes, especially those in high-risk sports with high-speed objects such as sticks, bats, balls, pucks, or aggressive body contact. Males are at higher risk for orbital fractures because of their increased incidence of trauma. The aperture of the bony architecture surrounding the eye does not allow an object with a radius of greater than 5 cm to penetrate the globe (14). The thin orbital floor (maxilla) and the medial wall (ethmoid) are the weakest portions of the orbit. A direct blow to the bony rim may not cause a bony rim fracture, but can be enough to increase intraorbital pressures (as the globe is compressed) resulting in a "blowout fracture" of the weakest point of the orbital wall, which is usually the floor of the orbit. Sphenoid: posterior orbit Related anatomical structures that can be injured during an orbital fracture include the optic nerve, periorbital fat, extraocular muscles, and the inferior orbital nerve. These injuries are multiple and can include corneal abrasion, lens dislocation, iris disruption, choroid tear, scleral tear, ciliary body tear, retinal detachment, hyphema, ocular muscle entrapment, and globe rupture. The patient should be questioned regarding epistaxis or clear fluid from nares or ears, loss of consciousness, visual problems, hearing problems, malocclusion, and facial numbness or tingling. Other specific questions regarding the eye include the presence of diplopia, painful eye motion (entrapment or periorbital edema), photophobia, flashes of light (retinal detachment), or blurred vision (hyphema, vitreous hemorrhage, retinal detachment) (14,16,17). This includes visual acuity, inspection for abrasions, laceration, foreign bodies, changes in pupillary dimension or reactivity to light. Any change in visual acuity, blood in the anterior chamber, or change in the shape of the iris should warrant a consult with an ophthalmologist. They should have their supraorbital ridge and frontal bone palpated for step-off fractures, and their hard palate and teeth palpated for stability. Evaluate the supraorbital, infraorbital, inferior alveolar, and mental nerve distributions for anesthesia.

Tese symptoms are important to recognize in manage What is meant by traumatic ment of the patient with spinal cord injury. Various traumas may result in dislocation and fracture of spinal vertebrae and cause spinal cord injury. In ad Syringomyelia is a cystic cavitation of the central spinal vanced countries, road trac accidents rank highest cord, most commonly in the cervical region. It can be among the etiological factors for traumatic spinal cord developmental, as in Chiari I malformation, or acquired, injury. According to an epidemiological study conduct usually due to traumatic spinal cord injury. It is clinically ed in Haryana, India, the predominant cause of injury characterized by segmental sensory loss, which is typi was falling from a height (45%), followed by motor vehi cally of a dissociated type, in which thermal and pain cle accidents (35%). Other causes of spinal cord trauma sensations are lost but tactile and proprioceptive sensa include sports injuries and acts of violence, primarily tions are preserved. In people with asymptomatic cervical be located in the hand, shoulder, neck, and thorax, is spinal stenosis, a fall or a sudden deceleration force can often predominantly unilateral (ipsilateral to the syrinx), cause a contusion in the cervical cord, even without any and can be exacerbated by coughing or straining. Spinal cord injury can be partial, nomic symptoms such as changes in skin temperature saving some motor or sensory functions or both, or it or sweating in the painful area can also be present. Pain can be complete, causing paralysis and complete senso may be the rst symptom, or it may appear after a long ry loss below the level of the lesion. Neurosurgical What are the characteristics treatment is considered only in cases with recent and quick progression. Pain following spinal cord injury is divided into below level pain and at-level pain. The latter is located in a After traumatic amputation, at least half of patients segmental or dermatomal pattern, within two segments experience phantom limb pain, which refers to pain above or below the level of spinal cord injury. It is related 192 Maija Haanpaa and Aki Hietaharju to central reorganization in the cerebrum, which ex burning pain, but aching, pricking, and lacerating pain plains the peculiar phenomenon of pain experienced is also common.

It is caused by donor T-lymphocytes proliferating and attacking the recipients tissues antibiotics for acne rosacea order zithromax american express. Prevention Graft-versus-host disease is prevented by gamma irradiation of cellular blood components to stop the proliferation of transfused lymphocytes. Signs and symptoms Excess iron deposits in tissues may result in organ failure, particularly of the heart and liver. Management and prevention Iron-binding agents, such as desferrioxamine, are widely used to minimize the accumulation of iron in these patients. Immunosuppression Blood transfusion alters the recipients immune system in several ways and immunosuppression has been a concern in the following two areas: 1 That tumour recurrence rates may be increased: prospective clinical trials have not shown a difference in the prognosis for transfused versus non-transfused patients or for recipients of autologous, as opposed to homologous blood. Massive (or large volume) transfusions generally arise as a result of acute haemorrhage in obstetric, surgical and trauma patients. The initial management of major haemorrhage and hypovolaemia is to restore the blood volume as rapidly as possible in order to maintain tissue perfusion and oxygenation. This requires infusing the patient with large volumes of replacement fuids and blood until control of the haemorrhage can be achieved. Morbidity and mortality tend to be high among such patients, not because of the large volumes infused but, in many cases, because of the initial trauma and the tissue and organ damage secondary to haemorrhage and hypovolaemia. However, the administration of large volumes of blood and intravenous fuids may itself give rise to a number of problems. If acidosis is present in a patient receiving a large volume transfusion, it is much more likely to be the result of inadequate treatment of hypovolaemia than due to the effects of transfusion. Management Under normal circumstances, the body can easily neutralize this acid load from transfusion and the routine use of bicarbonate or other alkalizing agents, based on the number of units transfused, is unnecessary. Hyperkalaemiathe storage of blood will result in a small increase in extracellular potassium concentration, which will increase the longer it is stored. This rise is rarely of clinical signifcance, other than in neonatal exchange transfusions. Management See Section 11: Paediatrics & Neonatology for neonatal exchange transfusion. Prevention Use the freshest blood available in the blood bank and which is less than 7 days old. Citrate binds 150 A D V E R S E E F F E C T S O F T R A N S F U S I O N calcium which reduces the bodys ionized calcium level. Management Following transfusion, the anticoagulant citrate is usually rapidly metabolized to bicarbonate. It is therefore unnecessary to attempt to neutralize the acid load of transfusion. The routine prophylactic use of calcium salts, such as calcium chloride, is not recommended. However, their use should be considered if there is clinical or biochemical evidence of a reduced ionized calcium. Red cell concentrates and plasma-reduced units lack coagulation factors which are found in the plasma component. In addition, dilution of clotting factors and platelets will occur following administration of large volumes of replacement fuids. Massive or large volume transfusions can therefore result in disorders of coagulation. Management In order to avoid the indiscriminate use of fresh frozen plasma and cryoprecipitate, use these products only when there is clinical or laboratory evidence that they are needed. Preventionthe prophylactic use of platelet concentrates in patients receiving large volume blood transfusions is not recommended. Management Treatment should be directed at correcting the underlying cause and at correction of the coagulation problems as they arise. Hypothermiathe rapid administration of blood or replacement fuids directly from the holding refrigerator can result in a signifcant reduction in body temperature. Hypothermia can result in various unwanted effects (see Avoiding Hypothermia in Section 12. Management If there is evidence of hypothermia, every effort should be made to warm blood and intravenous fuids during large volume transfusions. Management Filters are available to remove microaggregates, but there is little evidence that their use prevents this syndrome. However, responsibility for the decision to transfuse ultimately rests with individual clinicians. They should also be based on knowledge of local patterns of illness, the resources available for managing patients and the safety and availability of blood and intravenous replacement fuids. Finally, if in doubt, ask yourself the following question: 10 If this blood was for myself or my child, would I accept the transfusion in these circumstances Many transfusions are given that do not beneft the patient, could do harm and could have been avoided. Simple preventive measures and the use of oral iron replacement can greatly reduce the prevalence of iron defciency anaemia and reduce the need for transfusion. In endemic malarial areas, there is a high risk of transmitting malaria by transfusion. It is therefore important to give the transfused patient routine treatment for malaria. Section 9 is not intended to be a substitute for standard books on medicine and haematology, but aims to help you to: Manage patients so as to avoid the need for transfusion, wherever possible Know when transfusion is necessary. Alternatively, the anaemia may be detected by, for example, a screening programme or during the investigation of some other condition. The presence of anaemia indicates a nutritional defciency and/or some pathological condition. A of the epidemiology of anaemia and relevant conditions in feature of iron defciency the locality. Athe rate at which anaemia develops usually determines the severity feature of iron defciency anaemia. Severe anaemia, whether acute or chronic, is an important factor in reducing the patients tissue oxygen supply to critical levels. Acute blood lossthe clinical features of haemorrhage are determined by the volume and rate of blood loss and by the patients capacity to make the compensatory responses described in Section 3. A similar rate of blood loss may lead to decompensation and hypoxia in a patient who is elderly, has severe cardiovascular or respiratory disease or who is already anaemic when the haemorrhage occurs. The clinical picture of acute blood loss can therefore range from nothing more than modest tachycardia to the full features of haemorrhagic shock (see Figure 9. However, the clinical features of anaemia may become apparent at an earlier stage when there is: A limited capacity to mount a compensatory response. This situation is often a clinical emergency, especially in young children, obstetrics and emergency surgery. Management may include the need for red cell transfusion (see Section 10: Obstetrics, Section 11: Paediatrics & Neonatology and Section 13: Trauma & Acute Surgery). Clinical assessment Clinical assessment should determine the type of anaemia, its severity and the probable cause or causes. For example, a family history of anaemia, or a history that suggests the patient has been anaemic since childhood, should alert you to the possibility of a haemoglobinopathy (see Section 9. The patients place of residence, diet, parity and obstetric history, history of bleeding, occupation, social habits and travel history may point to causes of anaemia such as nutritional defciency, drugs, alcohol abuse, malaria or parasitic infection. Examination of the patient may reveal signs of malnutrition, angular stomatitis and koilonychia associated with iron defciency, jaundice due to haemolysis, neurological abnormalities due to vitamin B12 defciency, fever and sweating accompanying malaria or bruises and haemorrhages suggesting a bleeding disorder. Laboratory investigations Once a clinical diagnosis of anaemia has been made, a full blood count, examination of the blood flm and red cell indices will enable the cause to be determined in most cases (see Figure 9. A features are misshapen microcytes, hypochromic macrocytes and feature of the red cells in, red cell fragments, and basophilic stippling.

Its used for drinking and wastewater treatment, air disinfection, the treatment of fruit and vegetable juices, as well as a myriad of home devices for disinfecting everything from toothbrushes to tablet computers. The use of ultraviolet light for surface disinfection within an array of facilities has started to increase due to its ease of use, short dosage times, and broad efficacy. A cell that cant reproduce is considered dead; since it is unable to multiply to infectious numbers within a host. 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. There has been concern with regard to the residual odors that have been noted after rooms are disinfected with ultraviolet light. Up to 80% of airborne dust in homes, offices, and other indoor environments is made up of dead human skin and hair. Skin and hair cells consist of keratin, a protein, while hair also contains cysteine, an amino acid. The human nose is extremely sensitive to thiols and can detect them at concentrations as low as 1 part per billion. 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. Systems are available to disinfect rooms and high traffic areas with common touchpoints, ambulances and other emergency service vehicles, ductwork, tools or equipment inside a disinfection chamber, continuous pass-through conveyors, and many more. It has long been available for biological safety cabinet disinfection and home water treatment as well.

The P1 domain, which consists of one helix and eight sheets links, the S and P2 domains. The Role of Glycans in Norovirus Attachment Non-enveloped virus entry is a multi-step process starting with viral attachment to target cells, followed by receptor engagement, endocytosis, cell membrane penetration, and uncoating that culminates in the delivery of the viral genome into the cytoplasm [5] 1). Notably, viral entry is a critical determinant of cell tropism, host range, and pathogenesis. The rst and often rate-limiting step of viral entry is virus binding to host cells, which is mediated by both host attachment factors and receptors. Attachment factors are host molecules that concentrate the virus on the cell surface but do not actively induce viral entry [5]. While attachment factors increase the eciency of viral infection, they are by denition not essential. In contrast, viral receptors are essential host molecules that specically bind the virus particle, induce a conformational change in the virus, and actively promote viral entry [5]. Notably, in some cases, the classication of host molecules involved in viral entry can be dependent on viral strain, host cell type, and culture conditions. Interestingly for noroviruses, both cell-associated and non-cell-associated host molecules that augment binding, albeit by diverse mechanisms, have been described. The firstand often rate-limiting step of viral entry is viral attachmenttoModel of norovirus entry. The first and often ratelimiting step of viral entry is viral attachmentthe cell surface. Cell-associated host glycans including terminal sialic acid and histo-blood group antigens to the cell surface. Following receptor engagement, the virus is to form a membrane portal that may enable viral genome release in the cytosol [34]. These and subsequent challenge studies was later correlated with host secretor status, i. However, other host glycans including sialic acid and heparan sulfate proteoglycans may play a role in viral attachment. The Role of Non-Glycans in Norovirus Attachment Important host and microbial molecules other than glycans have been reported to also facilitate norovirus attachment. Recently, bile salts were discovered as important cofactors for norovirus infection in vitro [31,38]. Interestingly, bile salts had been previously implicated as important factors for in vitro replication of porcine sapovirus, another member of the Caliciviridae family [66]. Bile salts are cholesterol derivatives produced and secreted from the liver into the gastrointestinal tract where they are further modied by intestinal bacteria. Notably, bile was required either during or after, but not before, viral adsorption [31]. It is also unclear whether bile salts alocalizes to cellular tight junctions and regulates tight junctionect virus stability or contribute to post-binding permeability [79]. In addition to the role of glycans and bile salts, phospholipids were also recently identied as key mediators in norovirus entry. Ceramide has also been implicated in porcine enteric calicivirus entry, albeit through a dierent mechanism [75]. In summary, both soluble and cell-associated molecules including glycans, bile salts, cations, and phospholipids can augment the binding of noroviruses to host cells. These pro-attachment molecules can bind directly to the norovirus capsid or aect the function or conformation of the host cell membrane or receptor. Outstanding questions on norovirus attachment include whether diverse attachment factors are synergistic, how attachment factors promote the binding of the virus at the molecular level, and how attachment factors regulate species, tissue, and cell tropism. Future work is needed to determine the role of such attachment factors in mediating host permissivity to norovirus infection and disease. Receptor Engagementthe second stage of viral entry, and the rst essential step, is receptor engagement [5]. Host cell receptor utilization informs our understanding of viral pathogenesis, cell and tissue tropism, species tropism, and immune evasion from the humoral immune response. At the base of this binding pocket is an aspartic acid that coordinates a cation and facilitates ligand binding [82,83]. Endocytosis and Uncoating Upon binding to the cell surface, caliciviruses undergo endocytosis. The viral genome must then escape the capsid and penetrate the endosomal membrane to enter the host cell cytoplasm. Viruses can hijack a number of distinct endocytic routes to gain entry into cells, including micropinocytosis, clathrin-dependent, caveolin-dependent, dynamin-dependent, and cholesterol-dependent pathways [5]. Upon virus internalization, the endosomal location of viral genome release can vary from the early endosome to the endoplasmic reticulum [5]. The various endosomal compartments have dierent pHs, and pH-dependence has been reported to be essential for other viruses [7,87,88]. Elucidating the mechanism of norovirus internalization may inform our understanding about norovirus entry, pathogenesis, and immune sensing. These vesicles, likely derived from multivesicular bodies, can contain a wide range of viral particle numbers, which can vary across viral species. Both enveloped and non-enveloped, or naked, virions can exist for a given virus; these different viral forms can confer different physiologic properties. The presence of a vesicle surrounding what are classically considered non-enveloped virions presents a challenge in understanding how non-enveloped viruses escape the vesicle and interact with their cellular receptors. This is because the viral capsid proteins which determine receptor utilization and tropism are cloaked by the lipid bilayer inside an extracellular vesicle. The differences between enveloped and naked virion entry has been best described for the hepatitis Viruses 2019, 11, 495 8 of 13 A virus in which enveloped and non-enveloped virions were recently demonstrated to enter cells by distinct intracellular trafficking routes [92,95]. Endosomal escape and viral uncoating, the last step in viral entry, culminate with the release of the viral genome into the host cytoplasm. Enveloped viruses directly fuse with the plasma or endosomal membrane, releasing their genome into the intracellular environment, while non-enveloped viruses can release their viral genomes through membrane lysis or utilize membrane-piercing structures [96].

The changes that we have talked about in this chapter present challenges for older adults in their daily lives antibiotic ear drops for dogs cheap zithromax 500mg without a prescription. Being sensitive to these challenges helps you understand how older adults are experiencing their lives. Instructor Notes:the purpose of this activity is to provide an experiential learning exercise to help students understand what the day-to-day routine may be for an older adult or adult with disability. When everyone is finished, bring the group together and start a discussion on their experiences. Materials needed: Sunglasses, with lens smeared with Vaseline 2 pairs yard gloves (thick, heavy kind) 3 pairs ear plugs or cotton balls Sugar packets and cups Toothpaste Newspaperthe amount of materials depends on the class size. Student #2 will give him or her a sugar packet and ask him or her to open it and put it in the cup. Student #2 will give him or her a tube of toothpaste and ask him or her to open it. What did it feel like to be the older adult with a hearing, visual, or dexterity impairment What did it feel like to watch the person with an impairment try to accomplish his or her task But think about ways in which you could help the person without doing it for them. For example, if an older adult is having trouble opening sugar packets, instead of opening the sugar packets for them all the time, what about finding another way to dispense sugar that she could more easily use, like a sugar container on the table Memory loss is not a predictable consequence of aging, and is generally the result of a medical issue. Urinary incontinence (leaking urine) affects only 10% of older adults, mostly women. Close to 80% of todays older adults live in their own home, either alone or with their spouse. What it takes to learn (amount of time, level of concentration) changes with age, and older people must learn to work at their own pace, practice new skills, and avoid competitive situations that favor youthful quickness. Older adults are quite skilled at integrating knowledge and skills acquired over the lifetime. Older adults with dementia may lose the ability to make certain decisions and this is determined by a doctor. When we make 191 decisions for an older person this is called paternalism, which means we are treating them like children. A decrease in sexual activity is frequently due to medication or the loss of a partner. Dementia affects 5-8% of people age 65-74, up to 20% of those 75-84 and up to 50% of those 85 and over. However, some older people are more likely to be below the poverty level: women, people over the age of 75, black older adults, and older adults living alone. This is because the older we get, the more diverse life experiences we have, which sets us apart from each other. A persons grouchiness might be misinterpreted if they are sick, in pain, or depressed. Although older people may be more likely to experience certain health conditions, not all older people are sick. For each of these systems, name one change related to aging and how this change might affect an older adult: a. Circulatory Changes in the circulatory system as we age: o In general, the flow of blood changes. Digestive Changes in the digestive system as we age: o Stomach cannot hold as much food. Respiratory Changes in the respiratory system as we age: o Older adults do not take in oxygen or breathe out carbon dioxide as well. Skeletomuscular Changes in the skeletomuscular system as we age: othe spine may change it may become shorter or more curved. Endocrine Changes in the endocrine system as we age 195 othe amount of hormones produced may change and the body may become less sensitive to the effect of hormones. As we get older, we may become more resistant to insulin, which keeps the body from turning glucose into energy. Urinary Changes in the urinary system as we age: o Bladder muscles weaker and stretched. Integumentary Changes in the skin, hair, and nails as we age: o Fat under the skin moves around so that there is less fat in some places and more in others. What losses might an older adult experience that would affect his or her emotional health As we get older we might experience many losses including the death of spouses, family members, and friends. Physical and cognitive decline that results in loss of independence, including loss of a home also affect emotional health. Example: Losing ones Urinary incontinence Most older adults live Older adults are unable memory is expected is a natural part of in nursing homes. Memory loss is It is a sign that there is age of 65 lives in learn (amount of time, not a predictable an underlying long-term care level of concentration) consequence of problem.

Ceiling/floor effects Ceiling effects (high number of seconds = slow gait velocity): the test is not useful for people unable to walk 25 feet. Normative Data: Normative data for healthy males, females in different decades between ages 20 and 70 have been published for the 25foot walk at comfortable (130146 cm/sec) and maximum (175253 14 cm/sec) speeds. Instrument use Equipment required Measured distance for a walking course and a stop watch or other timing device.
