This self-help book has been tested and is most useful for phobias and obsessive-compulsive disorder. Lifetime prevalence estimates for major depressive disorder are approximately 15% to 20%; 1-year prevalence estimates are 5% to 10%. Moreover, depression is characterized by high rates of relapse: 22% to 50% of patients suffer recurrent episodes within 6 months after recovery. Individuals suffering from major depression run a higher relative risk of coronary heart disease, type 2 diabetes and osteoporosis compared with the general popula- tion. In general, depressed individuals exhibit a less active life-style and have a reduced cardio-respiratory fitness in com- parison with the general population. Strong evidence demonstrates that lack of physical activity is associated with an un- healthier body mass and composition, and a biomarker risk profile for cardiovascular disease, type 2 diabetes, and osteo- porosis. A growing body of evidence suggests that exercise is an effective treatment for depression. For mild to moderate depression the effect of exercise may be comparable to antidepressant medication and psychotherapy; for severe depres- sion exercise seems to be a valuable complementary therapy to the traditional treatments. Exercise training not only im- proves depression, but also produces positive side effects on depression associated physical diseases and cognitive de- cline.

Its a good idea to be informed about caesarean births so that if the need arises you are well prepared buy tetracycline 250 mg overnight delivery. Insulin/Glucose infusion (drip) Women may need an insulin infusion to control the blood glucose levels during labour tetracycline 500mg overnight delivery, or when having a caesarean order cheapest tetracycline and tetracycline. This is more likely in women who have needed treatment with high doses of insulin during the pregnancy. Gestational Diabetes | 19 After the birth Gestational Diabetes will not lead to your baby being born with diabetes Your baby will be monitored carefully for the frst 24-48 hours (heart rate, colour, breathing, blood glucose levels). The midwives will perform blood glucose tests (using heel pricks) on your baby to make sure its blood glucose levels are not too low. Benefts of breastfeeding Breastfeeding soon after the birth, then every four hours, helps to maintain your babys glucose levels. Breastfeeding has also been shown to pass on the mothers immunity to the baby and help your weight control. For women who required insulin Insulin will usually be stopped after your baby is born. Your health team will advise you how often to monitor your blood glucose to see whether the levels have returned to normal (generally 4. Approximately 50% of women who have had gestational diabetes will develop type 2 diabetes within 10-20 years. If you have another pregnancy, there is a very high chance of developing gestational diabetes again. The healthy lifestyle information gained during pregnancy is valid for all Australians. Continue your healthy eating and activity routine and ask your doctor for a blood glucose test every 2 years.

The strongest predictor of diabetes complications is gly- caemic control and achieving HbA1c 7. However, standard treatment appears to be lacking and adjunctive strategies require consideration. Four databases were searched from inception until 28 March 2017: mellitus: A systematic review. This is an open access article distributed under the terms of the three reported statistically significant reductions (P < 0. Due to the significant heterogeneity of included studies, an overall effect could not be reproduction in any medium, provided the original determined. This review presents all available evidence on low-carbohydrate diets for type 1 author and source are credited. Data Availability Statement: All relevant data are within the paper and its Supporting Information files. Type 1 diabetes is an autoimmune condition characterised by the destruction of pancreatic Competing interests: I have read the journals beta cells and absolute insulin deficiency. Affected individuals have impaired glucose metabo- policy and the authors of this manuscript have the lism and are prone to chronic complications from hyperglycaemia, and acute complications following competing interests: Jessica Turton from hypoglycaemia and ketoacidosis. The standard treatment consists of daily injections of completed an internship (2016) at a private insulin and diet flexibility is encouraged. However, data from type 1 diabetes registries across nineteen Diabetes Federation. Kieron Rooney has given countries in Australasia, Europe and North America (n = 324,501) reported that 84% of talks for "Low Carb Down Under" on the patients exhibited HbA1c above this target [5]. It appears that current therapies are lacking in biochemistry of low carbohydrate diets and has been a collaborator on primary research effect and adjunctive strategies require consideration. In type 1 diabetes, blood glucose excursions are a function of the input of glucose from food, mainly carbohydrates (starch and sugars), and insulin from predominantly exogenous sources [8]. By reducing dietary carbohydrate, the error rate in determining the required exog- enous insulin amount is reduced and blood glucose fluctuations attenuate [4]. Consequently, less frequent and severe hyper- and hypoglycaemic episodes as well as a reduction in overall insulin requirements should result [9]. Demonstration of these benefits with carbohydrate restriction in type 1 diabetes patients have been recently reported [8, 10]. However, in accordance with the National Health and Medical Research Council recom- mendations for the management of type 1 diabetes in Australia, patients are advised to con- sume carbohydrates to the level of 4565% total energy intake [1112]. However, these approaches rely heavily on carbohy- drate counting and insulin dose adjustments. We set out to determine whether significant differences in type 1 diabetes management outcomes exist between low-carbohydrate diets and higher-carbohydrate com- parators. We also investigated whether primary nutrition studies of low-carbohydrate diets have different levels of effect depending on the degree of carbohydrate restriction. Citations and abstracts of all papers retrieved from these searches were downloaded into Endnote reference management software (Endnote X7. Dis- agreements were resolved by consensus through adjudication with a third independent researcher. Studies included in the review had to be primary research studies of interventions or exposures including controlled trials, cohort-type studies and case-control trials. In the case of multiple reports from the same study, we used the most complete or recently reported data. For studies investigating different levels of car- bohydrate restriction, the lowest reported or prescribed level of dietary carbohydrate intake was considered the intervention and the highest level was considered the comparator. Risk of bias assessments were conducted for methodological quality of each included study using the critical appraisal tool most appropriate for its design. For randomised controlled tri- als, the Cochrane Collaborations Risk of Bias tool for randomised studies was used [16]. This assesses bias as low risk, high risk or unclear risk across seven domains. For specificity, we separated blinding of participants and blinding of personnel into two separate domains. For pre-post intervention studies, the National Institute of Healths quality assessment tool for before-after studies with no control group was used [17]. This tool evaluates potential flaws in study methods or implementation using twelve closed questions.

Following a fall or blow on a clenched fist or forced abduction of the thumb (skiers) 250mg tetracycline fast delivery. Unstable as oblique and proximal fragment is attached to trapezium and distal fragment has strong muscles attached to it that pull it proximally cheap tetracycline generic. Transverse fracture is straightforward: Scaphoid cast Multiple metacarpal fractures: twisting and crush injuries discount 500mg tetracycline. Finckelsteins sign: pain on forcible adduction and flexion of the thumb into the palm. Stenosing tenosynovitis/inflamed tendon sheath of extensor pollicis brevis and abductor pollicis longus. If unstable (cant oppose fingers) then repair (adductor tendon may get in the way and prevent reattachment) Dislocation of the phalanges: usually always ligament injury as well. Buddy strapping + early mobilisation Phalangeal fractures: Buddy taping: encourage flexion, deny rotation, allow for swelling (ie not too tight) Dupuytrens Contracture: Painless fibrosis of the palmar aponneurosis (can also occur on the foot). Usually familial (associations with alcoholism and manual work over-rated), anti-epileptics. Causes puckering of the skin over the distal palmar crease and gradual flexion of the fingers (usually starts with ring finger). Prognosis worse if younger Ganglia: Painless, jelly filled swelling caused by a partial tear or bulging of a joint capsule. Carpal Tunnel Syndrome Compression of the median nerve as it passes through the carpal tunnel in the wrist Epidemiology: Common. Usually women 3 - 50 years Causes: Due to thickened tendons or synovitis in the carpal tunnel Rheumatoid arthritis Hypothyroidism Acromegaly nd Pregnancy (2 ary to oedema) Obesity Amyloid Diabetes Mellitus Idiopathic Symptoms: Pain/tingling in the hand and wrist classically in the median nerve distribution (palm and thumb, index and middle fingers). Wakes at night, shakes hand, cant get it comfortable Musculo-skeletal 249 Signs: Wasting of thenar eminence, weak thumb abduction and opposition (late signs). Quads contract to prevent buckling of the knee Foot Flat: Dorsiflexors slowly relax to bring foot to ground, and hip extensors propel body forward Mid stand: body directly over ankle Heel off: Triceps surae contract Toe off: Hallucis and flexor digitorum longus contract Swing phase (40% of the cycle): Acceleration: iliopsoas contracts (flexes hip), passive knee extension, dorsiflexors contract so foot clears the ground Mid swing Deceleration: hamstrings stop hyper-extension of the knee and gluteus maximus slows hip flexion Double stance: both feet on ground for 20% of the cycle when walking. When running this % reduces to 0% (ie swing > 50% of cycle so both feet off the ground at some point) Abnormalities of Gait Causes a limp The main causes of abnormal gait are: Pain Antalgic gait (non-specific). Pain shortened stance phase on affected leg, shortened swing of opposite leg Weakness Joint abnormality Usually noticed during stance phase when one leg is bearing the bodys weight Swing phase: Abnormal heel strike due to: Pain in hind foot (so land on forefoot) Quad weakness: Knee wont extend by itself, so lands flexed and at risk of buckling. Use hand to push thigh posteriorly (foot and hip fixed so backward pressure on distal thigh stops the knee collapsing). Look at hip and shoulder alignment Extensor Lurch or Gluteus Maximus Gait: Dont have enough strength in gluteus maximus to hold hip in extension risk that the torso collapses forward at the end of stance. Lurch torso backwards to compensate Flat Foot or Calcanial Gait: cant toe-off, instead lift whole foot off without extending big toe. Due to: Pain or Rigidity in the fore foot Weakness of plantar-flexors Swing Phase: Paralysis of foot and ankle dorsiflexors can cause one or more of the following during toe clearance: Steppage or Drop Foot Gait: flex knee more in swing phase so the foot clears the floor Hip-hike Gait: Lift pelvis to help the foot clear the ground. Can also be due to a stiff knee Circumduction Gait: Swing leg out to the side so the foot clears the ground. Can also be due to a stiff knee Abnormal pelvic rotation: Weakness of hip flexors on the swing side acceleration. If there is a discrepancy then flex both knees to isolate the discrepancy to above or below the knee Apparent leg length discrepancy: measure umbilicus to medial melleolus. If discrepancy but no real leg length discrepancy then postural cause Palpation: Groin: lumps: hernias, lymph nodes, femoral artery aneurysm pain is not hip pain Check for ilio-tibial band pain over the greater trochanter pain is not hip pain Range of motion: always state start and end: from X to Y degrees (eg adduction from 0 to 30 degrees) Compare sides Thomas test for fixed flexion deformity (ie not full extension): Bring up good leg with hand under the spine. When pelvis starts to flex the bad leg wont be able to remain straight if there is fixed flexion deformity. Patient lies with limb in lateral rotation and leg looks short Location: key issue is disruption of blood flow to the femoral head. If disrupted (via a fracture at or above a basicervical fracture) avascular necrosis Treatment: Operative mostly. Neck of femur: leg externally rotated, dislocation: leg internally rotated (in points out and out point in) Femoral shaft Fracture: Clinical: Mostly young adults. Soft tissue swelling/effusion takes up to a day Always ask about knees: Locking: question carefully to distinguish from pain-induced hamstring spasm Giving way Musculo-skeletal 253 Swelling Function: Difficulty with stairs (going up or down? Look for Bakers cyst protrusion of the synovium into the popliteal fossa Look: Get on bed Swelling Muscle wasting: measure thigh circumference Bony deformity Arthroscopy scars Get them to push their knee down into the bed to test: Extension (fixed flexion deformity) For muscle wasting in vastus medialis Can measure angles with a goniometer Feel: Feel for temperature compared with rest of leg and with other knee Feel for effusion (Meniscal pathology often produces an effusion) Stroke/bulge test Patellar tap Palpate joint line along tibial plateau (watch their face): Tenderness here may indicate a meniscal tear, above or below the joint line the meniscus wont be causing it. If damaged traumatically then urgent surgery (the key knee injury where you wouldnt wait for the swelling to go down before operating) Flex their knee. Measure distance from heel to buttock Poster Cruciate Ligament: o Feet back down on the bed leaving both their knees in 90 flexion. Extending the leg will cause pain/clicking Lateral lemniscus: internally rotate the tibia on the femur, apply varus pressure. Now Push it into Varus, this tests the lateral collateral ligament Lay the leg flat and repeat with the knee in full extension: tests all structures not just the collateral ligaments. If cant then effusion/synovitis Site on edge of bed with legs handing over: Look at the direction that the patellar points in. Have the patient flex and extend at the knee should follow an inverted J course Grind or Friction Test Straighten the leg with your hand over the patella Will cause painful grating if the central portion of the articular cartilage is damaged Patella apprehension test: Press the patella laterally and hold it slightly subluxed Watch the persons face and ask them to flex their knee If they grimace or show signs of pain then the test is positive and is diagnostic of recurrent patellar subluxation or dislocation. Check the Hip (pain is referred to the knee from there) Check the Ankle and the foot pulses, and distal neurology Knee Injury General principles of ligament injury: Pain + slight joint opening good (strain/partial rupture) No pain + big joint opening bad (complete rupture) Always x-ray adequately. Aim is to preserve as much of the meniscus as possible Lateral/Medial Collateral Ligament: Most common knee ligament injury Medial is attached to the medial meniscus. But if it is, consider check for fibular head fracture and common peroneal nerve damage Mechanical: Blow to medial/lateral side of knee pushing the joint into varus/valgus Presentation: Tenderness over ligament (unless complete rupture no pain), pain worse under varus/valgus stress, effusion Management: Isolated tears heal well without operating. May have ongoing instability Anterior Cruciate Ligament: Prevents posterior displacement of the femur on the tibia and hyperextension. Quads exercises decrease backwards tibial sag Patella Fractures: Comminuted: from blow to flexed knee (eg knee against dashboard). Put patella together (usually hard) or remove it (patellaectomy) Stellate: blow to patella that cracks but doesnt displace fragments. Patellar aching after prolonged sitting due to softening or fibrillation of the patellar articular cartilage. Conservative treatment: vastus medialis strengthening Disruption of extensor mechanism: Rupture of Rectus Femoris: sudden violent contraction transverse tear. Conservative treatment: ice, elevation, analgesia, mobilisation within limits of comfort. Functional deficit negligible Ruptured Quadriceps tendon: sudden violent contraction.

Appropriate conditions generic 500mg tetracycline with visa, most importantly an alkaline pH brought about by the ductal bicarbonate secretion cheap tetracycline 250 mg overnight delivery, should be present for the digestive enzymes to be active order 500 mg tetracycline with visa. Endopepsidases such as trypsin and chymotrypsin cleave peptide bonds in the middle of the protein, called endopeptidases (trypsin and chymotrypsin), or at the carboxyl endwhereas (carboxypeptidases act at the carboxyl terminus. Importantly, both amylase, and lipase, are secreted into the small intestine in their active forms. The effective action of lipase is more complex than that of either pancreatic proteases and amylase. This complexity accounts for the relatively low survival of lipase among the digestive enzymes. In fact, in pancreatic exocrine insufficiency, frequently only fat maldigestion is evident. Its action results from emulsification of the food bolus, which is effected by the churning motion of the stomach and the action of bile acids. Colipase binds to lipase, stabilizes it, and prevents it from being inhibited and removed from the oilwater interface by bile salts. Perturbation of any of these processes will adversely affect the action of lipase on fats. Colipase binds to lipase to stabilize the lipase in a manner that First Principles of Gastroenterology and Hepatology A. Shaffer 589 prevents lipase from being inhibited and removed from the oilwater interface by bile salts. Secretion by centroacinar cells and by cells of the extralobular ducts of the pancreas. Chloride concentrations (right) were determined on fluid collected by micropuncture, and the bicarbonate concentrations were inferred from the fact that the fluid is isotonic. The first pattern is basal secretion, which is punctuated every 1 or 2 hours by bursts of increased bicar- bonate and enzyme secretion that last 10 to 15 minutes. The second pattern is the postprandial stage, which results from a complex interaction of neural and hormonal mechanisms. The cephalic phase occurs in response to the sight, smell and taste of food and is mediated by the vagus cholinergic nerves. The gastric phase occurs in 3 response to distention of the stomach, which affects vagova- gal neural reflexes and stimulates the release of gastrin. Both vagal reflexes and gastrin stimulate pancreatic enzyme secretion and gastric parietal cell acid secretion. The intestinal phase, which is initiated in the duodenum, accounts for the major stimulation of both enzyme and bicarbonate secretion. As the chyme reaches further into the small intestine, a number of hor- mones are released which are capable of inhibiting both basal and stimulated pancreatic secretion, and therefore serve as feedback inhibitory mechanisms on enzyme and bicarbonate secretion. Pancreatic Function Test The diagnosis of pancreatic insufficiency is quite evident in the presence of thestrongly suggested by the clinical triad of pancreatic calcification, steatorrhea and, less commonly, diabetes. These radiological tests demonstrating characteristic structural abnormalities of the pancreas, coupled with steatorrhea and or diabetes, are largelyso strongly suggestive of pancreatic insufficiency that often a clinican will not proceed to functional testing of the gland itself for diagnosis. Steatorrhea resulting from fat malabsorption has typical clinical features (foul-smelling floating stools, oil droplets). It ) and appears earlier than protein malabsorption (azotorrhea) in pancreatic exocrine insufficiency, because of the low survival of lipase. Nonetheless, development of steatorrhea and azotorrhea requires the destruction of at least 90% of the pancreas. Diabetes is less common in pancreatic diseases, since the islets are remarkably resistant to damage during the inflammatory process. However, when diabetes is present, it follows a more brittle course, since the nonbeta cells producing the counter-regulatory hormones glucagon and somatostatin are also affected. OverPancreatic function tests were initially divised for diagnosis of pancreatic dysfunction. They the years, pancreatic function tests have been devised not only as a diagnostic tool, but more frequently as research tools. These pancreatic function tests may can be divided into two main groups: direct or indirect tests requiring (duodenal intubation,) and indirectnon-invasive, indirect tests. Of the pancreatic function tests, the direct invasive tests are the gold standard. Sleisenger & Fordtrans Gastrointestinal and Liver Disease: Pathophysiology/Diagnosis/Management 2006; page 1197-1199; and 2010, page 928. These tests are based on the principle that as pancreatic flow increases with stimulation, there is a progressive increase in bicarbonate con- centration (> 80 mEq/L) and a corresponding decrease in chloride concentra- tion. However, the accuracy of the Lundh test is affected by small bowel mucosal disease, rate of gastric emptying and surgical interruption of the gastroduodenal anatomy. Neither test is frequently used because of their disadvantages, including the prolonged (23 hours) and unpleasant intubation, and the difficulty of accurate tube positioning. This technique allows the measurement of pure pancreatic juice secretion uncontaminated by biliary or intestinal secretion. Here, tThe patient is placed on a 100 g/day fat diet and the stool is collected daily for three days. Individuals with normal pancreatic function excrete less than 7% of the total amount of fat ingested, whereas those with pancreatic exocrine insufficiency excrete more than 20%. Only a few other conditions, such as extensive small bowel mucosal disease and short bowel syndrome, could cause such a degree of fat malabsorption, such as very extensive small bowel mucosal disease and short bowel syndrome. The major drawbacks ofto stool fat estimations are the lack of specificity and the inconvenience of collecting and analyzing the specimens. Measurements of stool nitrogen and stool chymotrypsin have not proved superior to fecal fat determinations. Attempts to screen for steatorrhea with less offensive tests (such as urine oxalate levels, C- triolein/3H-oleic acid assimilation test, and tripalmitate or palmitic acid breath tests) are promising but not generally accepted. The bentiromide test is a urinary test that directly determines pancreatic chymotrypsin secretion. Intestinal mucosal, liver and kidney diseases under- standably adversely affect the accuracy of the bentiromide test; m. The pancreolauryl test, using fluorescein dilaurate, has been extensively evaluated in Europe. However, it can detect only severe pancreatic insuffi- ciency and is therefore rarely used. Chronic pancreatitis may give rise to an abnormal Schilling test, but rarely causes clinical B12 deficiency. Vitamin B12 is initially bound to an R factor present in saliva, which stabilizes B12 in acidic gastric pH. Pancreatic enzymes release the R factor from B12 to allow B12 to bind to the intrinsic factor secreted by the stomach, which is required for B12 absorption at the terminal ileum. It is elevated during an attack of pancreatitis and in renal failure, and is decreased in severe pancreatic insufficiency, cystic fibrosis and insulin-dependent diabetes without exocrine insufficiency. The levels of trypsinogen in cystic fibrosis decrease with age if the pancreas is involved. Patients with pan- creatic insufficiency who have ongoing inflammation may have normal or raised levels.

Self monitoring of blood glucose for people with type 2 diabetes can guide adjustment of insulin or other medication for patients and health ++ 1 professionals as part of a comprehensive package of diabetes care quality 500mg tetracycline, encourage self-empowerment and promote better self-management behaviours buy tetracycline 250mg fast delivery. Conversely self monitoring may fail to improve diabetes control and has been associated with negative psychological outcomes buy tetracycline 250 mg lowest price. One systematic review identified poor quality studies which assessed the effect of frequency of self monitoring on glycaemia in people with type 1 diabetes. However, one small crossover study in adults with type 1 diabetes reported that there was no difference in HbA1c between those who tested twice each day for a week compared with those who tested four times daily on two non-consecutive days per week. These systems are generally only considered for use by patients who experience particular difficulties in maintaining normal glucose levels or who have been transferred to continuous subcutaneous insulin infusion therapy (see section 5. No significant differences were found between the groups in the number of hypo- and hyperglycaemic events. The between-group difference was not significant among those who were 15 to 24 years of age (mean difference, 0. Many of the studies cannot be compared as the patient groups were different and glucose monitoring was usually just one part of a multifactorial intervention programme. Rates of hypoglycaemia, however, were very low overall and the study only followed up patients for 12 weeks. Extrapolation from the evidence would suggest that specific subgroups of patients may benefit. These include those who are at increased risk of hypoglycaemia or its consequences, and those who are supported by health professionals in acting on glucose readings to change health behaviours including appropriate alterations in insulin dose. Further research is needed to define more clearly which subgroups are most likely to benefit. B Routine self monitoring of blood glucose in people with type 2 diabetes who are using oral glucose-lowering drugs (with the exception of sulphonylureas) is not recommended. Studies suggest that urine testing is equivalent to blood testing but these studies were generally carried out in an era when HbA1c levels were higher than would now be considered acceptable, limiting the applicability of these data to current practice. The meta-analysis suggests that a very modest improvement in glycaemic control is associated with urine testing versus placebo (HbA1c -0. B Routine self monitoring of urine glucose is not recommended in patients with type 2 diabetes. In the emergency department setting, a cross-sectional study suggested that blood ketone measurement may be a more accurate predictor of ketosis/acidosis than urine ketone measurement. There is insufficient evidence to make a recommendation on the routine measurement of ketones in patients with type 1 or type 2 diabetes. Smoking cessation reduces these risks substantially, although the decrease is 61, 62 4 dependent on the duration of cessation. Men who smoke are three times more likely to die 55 aged 45-64 years, and twice as likely to die aged 65-84 years than non-smokers. Studies done among women during the 1950s and 1960s reported relative risks for total mortality ranging from 1. A pack year is calculated by multiplying the number of packs of cigarettes smoked per day by the number of years an individual has smoked. There is a suggestion that smoking may be a risk factor for retinopathy in type 1 diabetes64, 65 2+ but not in people with type 2 diabetes. A Healthcare professionals involved in caring for people with diabetes should advise them not to smoke. B Intensive management plus pharmacological therapies should be offered to patients with diabetes who wish to stop smoking. There is no clear evidence suggesting that pharmacological intervention or counselling strategies to aid smoking cessation in patients with diabetes should differ to those used in the general 4 population. B Healthcare professionals should continue to monitor smoking status in all patient groups. Health-enhancing physical activity is physical activity conducted at a sufficient level to bring about measureable health improvements. This normally equates to a moderate intensity level or above and can generally be described as activity that slightly raises heart rate, breathing rate and core temperature but in which the patient is still able to hold a conversation. Exercise is a subset of physical activity which is done with the goal of enhancing or maintaining an aspect of fitness (eg aerobic, strength, flexibility, balance). It is often supervised (eg in a class), systematic and regular (eg jogging, swimming, attending exercise classes). There is no gold standard and techniques range from heart rate monitoring to motion counters and self reports. Self report is the easiest format but there is often an over reporting of minutes spent in activity. The Scottish Physical Activity Questionnaire 4 is an example of one self report format that has known validity and reliability for assessing moderate activity. A rate of perceived exertion scale is useful for estimating exercise intensity, particularly in people with autonomic neuropathy who have reduced maximal heart rate. This risk reduction is consistent over a range of intensity and frequency of activity, with a dose- 2+ related effect. Greater frequency of activity confers greater protection from development of 2++ type 2 diabetes and this is valid for both vigorous- and moderate-intensity activity. All of these studies have shown a relative risk reduction varying from 46 to 58% in the development of type 2 diabetes. Programmes lasting from eight weeks to one year improve glycaemic control as indicated by a decrease in HbA1c levels of 0. No significant difference was found between groups in quality of life, plasma cholesterol or blood pressure. A People with type 2 diabetes should be encouraged to participate in physical activity or structured exercise to improve glycaemic control and cardiovascular risk factors. Limited research has addressed the economic impact of physical activity and exercise programmes. A systematic review of randomised and observational studies reported that exercise and physical activity programmes in people with type 1 diabetes do not improve glycaemic control but + 1 improve cardiovascular risk factors. B People with type 1 diabetes should be encouraged to participate in physical activity or structured exercise to improve cardiovascular risk factors. Greater amounts of activity should provide greater health benefits, particularly for weight management. Adults should also do moderate- or high-intensity muscle-strengthening activities that involve all major muscle groups on two or more days per week. If this is not possible due to limiting chronic conditions, older adults should be as physically active as their abilities allow. Older adults should also try to do exercises that maintain or improve balance if they are at risk of falling. In people with type 2 diabetes physical activity or exercise should be performed at least every second or third day to maintain improvements in glycaemic control. In view of insulin 4 adjustments it may be easier for people with type 1 diabetes to perform physical activity or exercise every day. A combination of both aerobic and resistance 1++ exercise appears to provide greater improvement in glycaemic control than either type of exercise alone. Expert opinion suggests using social-cognitive models and making advice 4 person-centred and diabetes specific.
