    Power wheel chair is one type of wheel chairs which is also referred and known as Electric Power Wheel Chair or (EPW). An Power wheel chair is used to move such wheel chairs instead of pushing by some attendant or by hand rims. It also has navigational controls so that it can be moved to any desired direction. Power wheel chairs are suitable for those, who are weaker to move the manual wheel chair using the hand rims and also provides its users a level of comfort. The user can control its speed and direction by a joystick sort of control while sitting on the chair. There are many different types of Power wheel chair and finding the appropriate one will depend on each individual's medical condition. Wheelchairs can be manual or electrically powered. Manual wheelchairs can come in either a folding or rigid design. Rigid type wheelchairs tend to be lighter and more easily maneuvered and should be used by more active wheelchair users. Folding wheelchairs would be an excellent choice for individuals needing to use the wheelchair for travel on a frequent basis. Many people have disabilities that make it difficult to propel themselves in a manual wheelchair and in this situation an electrically powered wheelchair may prove more useful. Power chairs are little bit more complex and the user can control it with minimum effort. This kind of chair will give extraordinary maneuverability, stability and power and it is perfect for people who want more from their wheelchairs.

    Bariatric wheelchairs (often referred to as extra wide wheelchairs or heavy duty wheelchairs) are strong enough to accommodate almost any user. Just like lighter manual chairs, bariatric wheelchairs are all foldable and feature armrests and swing-away footrests - but they differ quite a bit in their construction. While lightweight wheelchairs often employ materials like aluminum or titanium alloy, a bariatric wheelchair is usually fashioned from steel. Karma 8020 X Heavy Duty Wheelchair: It comes with detachable swing away footrests. The wheel chair has flip-back armrests. It comes with centre of gravity adjustment. The wheel chair has wide profile casters. Seat Size 20'' inch & 22'' inch Total Weight 17 K.G. Heavy duty wheelchairs (often referred to as extra wide wheelchairs or bariatric wheelchairs) are sturdy enough to accommodate almost any user. Just their lighter cousins, manual chairs, heavy duty models all fold and feature arm rests and swing-away footrests - but they differ quite a bit in their construction. Heavy duty wheelchairs require more strength to push by the caregiver and by the user, if the chair is self-propelled. In some cases, it may be wise for the caregiver to ask for assistance from another person in order to push the wheelchair safely. Karma 8520 Heavy Duty Wheelchair: It comes with detachable swing away footrests. The wheel chair has flip-back armrests. It comes with centre of gravity adjustment.

  • androgen-deprivation therapy in males with prostatic cancer may be associated with an increased risk for T2D, which may be caused by negative effects on insulin sensitivity
  • insulin sensitivity, measured by HOMA, improved in both groups and with a significantly greater degree when testosterone was added to supervised D&E
  • Fasting insulin concentrations, a good representative of insulin sensitivity, did show a significant correlation with changes in circulating androgen levels, an observation in support of Pitteloud et al (2005), who showed a direct relationship between insulin sensitivity and circulating testosterone concentrations using the hyper-insulinemic euglycemic clamp technique
  • 52 weeks of testosterone treatment also significantly improved circulation levels of adiponectin and hsCRP, key serum markers of insulin sensitivity and hepatic steatosis
  • The changes in both adiponectin and hsCRP were significantly correlated with the therapy-induced changes in bioavailable testosterone
  • a negative correlation was found between hsCRP levels and bioavailable testosterone
  • serum PSA concentrations did not differ between the 2 treatment groups, indicating that short-term testosterone administration appears to be acceptably safe

Lightweight Wheelchair With Padded Armrests - 0 views

    Transport wheelchairs or companion chairs are companion wheelchairs where the purpose is for a companion to push the user. Most of our transporters have swing-away leg rests, fixed armrests, and side panels. Instead of the usual 'large back - small front' wheels typical of most wheelchairs, light travel chairs have four small wheels providing much easier maneuverability of the chair. This type of lightweight wheelchair is often referred to as a "transfer chair" and is typically used for shorter trips. Since it's geared towards storability and portability, it features four smaller wheels and dispenses with the larger, rear-mounted wheels that characterize standard wheelchairs. Transport wheelchairs construction ensures that it's always foldable and portable wheelchair, but does so at the expense of self-propulsion. Instead, a transport chair is built so that a caregiver can easily push the user. Transport Wheelchair is constructed of tough and light aluminum. Its comfort features include nylon upholstery, swing-away footrests and padded armrests. The seatbelt adds safety, while the composite wheels make mobility convenient.

    Lightweight portable wheelchairs usually refers to the feature that a wheelchair may have, collapsible meaning that it is a foldable wheelchair, unlike rigid chairs that are usually not foldable, this includes sports wheelchairs, basketball wheelchairs, and active wheelchairs. Lightweight portable wheelchairs usually have a very light frame that is complete with a foldable feature, this includes folding the wheelchair seat and components into a compact shape, that can be stored into the trunk of a vehicle, or a storage space for example. Wheelchairs are the new norm in the wheelchair community, the foldable and light frame has become very popular with wheelchair users who prefer to use a lightweight wheelchair that can also be folded for convenience, and to boost the time it takes to do daily routine. The frame of the chair is foldable, including the seat, sometimes the backrest, foldable footrests, or in some cases collapsible push bars for caregiver propelled wheelchairs.

How We Read Oncologic FDG PET/CT | Cancer Imaging | Full Text - 0 views

  • In early PET literature focusing on analysis of solitary pulmonary nodules, some researchers defined malignancy based on a SUVmax threshold of greater than 2.5
  • We contend that SUV analysis has virtually no role in this setting.
  • tumours grow as spheres, whereas inflammatory processes are typically linear
  • ...35 more annotations...
  • Far more important than the SUVmax is the pattern rather than intensity of metabolic abnormality and the correlative CT findings
  • Descriptively, we define SUV < 5 as “low intensity”, 5–10 as “moderate”, 10–15 as “intense” and >15 as “very intense”
  • Evolving literature suggests that intensity of uptake is an independent prognostic factor and in some tumour subtypes superior to histopathologic characterisation.
  • aerobic glycolysis
  • Our practice of thresholding the grey and colour scale to liver as detailed above results in similar image intensity to a fixed upper SUV threshold of 8 to 10
  • The advantage of using the liver as a reference tissue is also aided by this organ having rather low variability in metabolic activity
  • When the liver is abnormal and cannot be used as a reference organ, we use the default SUV setting of an upper SUV threshold of 8
  • One of the most challenging aspects of oncologic FDG PET/CT review, however, is to recognise all the patterns of metabolic activity that are not malignant and which consequently confound interpretation
  • Many benign and inflammatory processes are also associated with high glycolytic activity
  • Future articles in the “How I Read” series will address the specific details of reading PET/CT in various cancers
  • The intensity of uptake in metastases usually parallels that in the primary site of disease
  • For example, discordant low-grade activity in an enlarged lymph node in the setting of intense uptake in the primary tumour suggests it is unlikely malignant and more likely inflammatory or reactive
  • By CT criteria the enlarged node is ‘pathologic’ but the discordantly low metabolic signature further characterises this is as non-malignant since such a node is not subject to partial volume effects and therefore the intensity of uptake should be similar to the primary site
  • The exception is when the lymph node is centrally necrotic as a small rim of viable tumour is subject to partial volume effects with expectant lower intensity of uptake; integrating the CT morphology is therefore critical to reaching an accurate interpretation
  • Small nodes that are visualised on PET are conversely much more likely to be metastatic as such nodes are subject to partial volume effects.
  • The exception to this rule is tumours with a propensity for tumour heterogeneity at different sites
  • The combination of FDG and a more specific tracer, which visualises the well-differentiated disease can be very useful to characterise this phenomenon
  • “metabolic signature”
  • For the majority of malignant processes, the intensity of metabolic abnormality correlates with degree of aggressiveness or proliferative rate.
  • a negative PET/CT study in a patient with biopsy proven malignancy would be considered false-negative
  • Warburg effect
  • There, however, are a significant minority of tumours that utilise substrates other glucose such as glutamine or fatty acids as a source of the carbon atoms required for growth and proliferation
  • This includes a subset of diffuse gastric adenocarcinomas, signet cell colonic adenocarcinomas and some sarcomas, particularly liposarcoma
  • There may be a role for other radiotracers such as fluorothymidine (FLT) or amino acid substrates in this setting.
  • Some tumours harbour mutations that result in defective aerobic mitochondrial energy metabolism, effectively simulating the Warburg effect
  • patients with hereditary paraganglioma and pheochromocytoma highlight this phenomenon
  • These have intense uptake on FDG PET/CT despite often having low proliferative rate.
  • Uterine fibroids, hepatic adenomas, fibroadenomas of the breast and desmoid tumours are benign or relatively benign lesions that can have quite high FDG-avidity.
  • Metabolic activity switches off rapidly following initiation of therapy
  • Common examples where patients have commenced active therapy but the referrer is requesting “staging” includes hormonal therapy (eg. tamoxifen) in breast cancer, oral capecitabine in colorectal cancer or high dose steroids in Hodgkin’s lymphoma
  • It is therefore critical to perform PET staging before commencement of anti-tumour therapy
  • The potential advantage of routine diagnostic CT is improved anatomic localisation and definition
  • Without intravenous contrast, additional identification of typical oncologic complications such as pulmonary embolism or venous thrombosis cannot be identified
  • If the study is performed as an “interim” restaging study after commencement of therapy but before completion, in order to reach a valid or clinically useful conclusion findings must be interpreted in the context of known changes that occur at a specific timing and type of therapy
  • The most well studied use of interim PET is in Hodgkin’s lymphoma where repeat PET after two cycles of ABVD-chemotherapy provides powerful prognostic information and may improve outcomes by enabling early change of management
  •  
    good read on the PET/CT scan reading.  They mention that tumors are spheres and inflammation is linear, yet inflammation coexists with cancer; hard to simply delineate these on simple terms. I do agree aon the metabolic signature of the PET/CT scan
