Any mental health clinician working in this field must be able to assess mental disorder (including substance misuse and personality disorder) medications zopiclone purchase cheapest brahmi and brahmi, motivation and capacity symptoms 5th disease effective brahmi 60caps. Given the different emphases in training and clinical practice symptoms pulmonary embolism buy brahmi 60 caps with visa, it is preferable treatment action group buy generic brahmi 60caps online, where possible chapter 7 medications and older adults cheap brahmi 60caps line, for psychiatrists and nurse specialists to assess mental disorder and psychologists and/or counsellors to assess motivation medications qt prolongation purchase brahmi 60 caps mastercard. It is most important that the assessing mental health clinician is familiar with transplantation procedures, timescales, risks and outcomes. In the context of living liver donation, it is best practice to refer potential donors to clinicians who are already familiar with the organ-specific issues rather than assuming a level of knowledge through living kidney donation alone. There is currently no evidence to guide consensus or recommendations in most areas. Possible coercion and/or pressure should be considered when assessing motivation in the mental health assessment. This is also a requirement of the Independent Assessment for the Human Tissue Authority (see section 6. Where the next of kin is the potential recipient, the interviewee should be the next nearest relative or a close friend, as nominated by the potential donor. Guidelines for the psychosocial evaluation of living unrelated kidney donors in the United States. Initial donor triage can be performed using a standardised questionnaire by telephone interview or online. The organisational details for evaluating a prospective donor will vary between centres, reflecting available resources and personnel. The pace of donor assessment must be tailored according to the rate of decline of recipient liver function, taking into account specific clinical and donor circumstances. Careful assessment must be undertaken to establish both donor and recipient risks, such as donor comorbidity and potential disease transmission. The evaluation process aims to provide a systematic physical and psychosocial assessment of risk, the provision of informed consent, and the confirmation of autonomous motivation. This requires an experienced clinical team and a clear separation of donor and recipient clinical interests throughout. The following provides a framework for donor evaluation, recognising that each donor presents unique circumstances in which adjustments to the protocol may be required. This manages expectations for both the donor and recipient and avoids unnecessary anxiety, healthcare costs, inconvenience, and the risks of the evaluation process. Investigation may reveal previously undiagnosed disease that could prejudice future life, health insurance or specialist employment. An outline of the investigation protocol must be provided with specific mention of possible allergic reactions to intravenous contrast administered at abdominal imaging and the risks attached to a liver biopsy. However, donor confidentiality remains paramount and the reasons for declining a donor should not be volunteered to the recipient or other family members without explicit consent. A generic statement about the suitability of a donor with reference to the stringent assessment criteria can be helpful in providing an explanation. The donor should be informed of this ethical principle before assessment (see section 6). Enquiries about living donation originate predominantly from recipient family members, of whom a significant number will be unsuitable to be considered as donors. Emphasis is placed on the earliest possible identification of these inappropriate donors, given the intensive labour and cost resources of assessment. It is recommended that an initial telephone interview, followed up by a standardised triage questionnaire is completed by a senior transplant coordinator / specialist nurse. Potential contraindications to proceeding with assessment can be discussed within the multi-disciplinary team at an early stage. If the donor and recipient are not compatible, this provides an early opportunity to enquire about other potential donors. In most units, donor assessment at this stage will be arranged by a senior transplant coordinator / specialist nurse supported by a clinician. The clinician, normally a physician / hepatologist, undertakes the medical examination of the potential donor. To avoid conflict of interest, the donor clinician should not have direct responsibility for the care of the transplant recipient. A senior surgeon will take responsibility for both donor and recipient surgical safety. Additional support from radiology, cardiology, haematology and infectious disease colleagues may be necessary. This is judged from the health professionals? perspective rather than that of the potential donor, who is likely to be less risk averse. Best practice includes a standardised questionnaire and a pre-determined investigation order set. It is important to emphasise that the pace of the donor work up must be driven by donor safety and the provision of adequate time for informed consent, even when the potential recipient is very sick. Morbidity and mortality is disproportionately higher in older patients after hepatectomy, both in disease-generated and living-donor procedures. The medical evaluation, particularly of the cardiovascular system, needs to be especially rigorous in older donors. Formal testing to exclude occult ischaemia is recommended in donors of 45 years or over. Defining an upper age limit for liver donation is not feasible as other individual donor factors and the volume of the proposed liver resection required must be taken into account. There are specific considerations when assessing young mothers/female donors for donation:? Early counselling should be offered about non-pharmacological or progesterone-only contraception. Combined oestrogen and progestogen preparations should be avoided and/or stopped due to an increased risk of thrombosis. They should be advised to lose weight prior to donation and to maintain their ideal weight following donation. Peri-operative wound and urinary infection, venous thrombosis and cardiorespiratory events are more frequent. The frequent co-existence of obesity with the metabolic syndrome and fatty liver disease adds to complexity and risk. All overweight potential donors need careful evaluation of the liver parenchyma for macrosteatosis by imaging-based methodology, and potentially liver biopsy (see section 8. This is crucial as hepatic steatosis is a recognised risk factor for poor graft function; a recent systematic review showed an increased risk of poor graft outcome in livers with moderate-severe steatosis (6). Mild to moderate hypertension that is controlled with one or two antihypertensive agents is not a contraindication to donation providing significant end organ damage has been excluded. Consideration of patients with diabetes requires careful evaluation of the risks and benefits. In the absence of evidence of target organ damage and having ensured that other cardiovascular risk factors such as obesity, hypertension or hyperlipidaemia are optimally managed, diabetics can be considered for liver donation. Cardiovascular stress testing should be routinely performed in the majority of this patient group (see section 8. Cardiomyopathy, particularly hypertrophic cardiomyopathy (incidence 1:500), is the most common cause of sudden cardiac death in apparently healthy young people who would otherwise be ideal donors (7). The presence of overt cardiac disease will exclude most individuals as potential donors. In view of the relative risk associated with donor hepatectomy in comparison with donor nephrectomy, a lower age threshold of 45 years (which approximates to a 3-5% risk of coronary disease) is recommended. Coronary vessel calcium scoring appears to be the best discriminant investigation for coronary artery disease. Functional capacity can be assessed formally with a treadmill or more simply using the Duke Activity Status Index (a short questionnaire). Where there is uncertainty about functional capacity or identification of other risk factors, cardiology review is recommended. Investigation protocols are influenced by local service provision and access to the different modalities for assessment. It quantifies the functional capacity to respond to increased metabolic demands and generates a patient-specific measure of risk. The individual risk of thrombosis following surgery can be more accurately defined by characterising underlying genetic profiles and performing a thorough thrombophilia screen. An extensive panel of investigations (acquired and genetic risk factors) is recommended (see section 8. Prophylactic anticoagulation will be suitable for most low-risk candidates but will be absolutely contraindicated for certain profiles. Input from a haematologist with an interest in sickle cell disease is recommended. Thalassaemia Patients with thalassaemia (major, intermedia and haemoglobin H disease) are not suitable for living liver donation as their requirement for blood transfusions causes iron overload and associated liver damage. Haemoglobin C & Haemoglobin E these haemoglobinopathies may be seen in donors of non-northern European heritage. Neither should pose a problem to liver donation except where Hb C is combined with sickle haemoglobin i. Such patients behave like patients with sickle cell disease and therefore should not be considered. Red cell membrane disorders these disorders, including hereditary spherocytosis, hereditary elliptocytosis and inherited haemolytic anaemias may be acceptable in mild forms. Expert haematological review of donors presenting with these disorders is required. However, case reports of transplantation mediated alloimmune thrombocytopenia associated with the transfer of donor anti platelet alloantibodies do indicate a potential for harm, and careful risk assessment and counselling is indicated (16). Imaging must assess fatty infiltration in addition to the biliary and vascular anatomy. The topics that need to be covered in the clinical history and laboratory screening tests for chronic liver disease have been listed previously. Imaging of the liver is performed to investigate for signs of chronic disease, the presence of portal hypertension, and fatty liver disease. The latter is a common finding and the level of steatosis influences donor and recipient outcomes after liver transplantation (see sections 9. Among living liver donors, a residual liver with a fat content of less than 5% shows better regeneration than one with macrosteatosis between 5?30%. As the level of steatosis increases from mild to moderate (30%) to severe (60%), the risk of graft dysfunction and renal failure in the recipient increases (6). Early mortality and the frequency of severe ischemia-reperfusion injury also increase significantly. For these reasons, imaging is performed to allow an estimation of fat quantification. Ultrasonography is a sensitive modality for screening for chronic liver disease but, although it can be used as a qualitative screening tool for the presence of fat, it is not sufficiently accurate for quantification. Hepatic attenuation measurements and calculation of the hepatic attenuation index require expert radiology expertise. The sensitivity and specificity of these imaging modalities are technique and operator dependent and vary based on the degree of steatosis present. Increasing degrees of steatosis also increase the sensitivity of the imaging modalities. In one study, the presence of >33% fat on liver biopsy was optimal for the accuracy of estimation of steatosis. However, no imaging modalities are able to reliably quantify the amount of steatosis or distinguish between simple steatosis and steatohepatitis (17). Where estimates of fat infiltration exceed 10-20% or whenever there is serological evidence of a liver disorder, careful consideration of liver biopsy is needed. The threshold for this invasive procedure, with its attendant risk of bleeding, has to be weighed against the valuable information that histological review often provides. In fatty liver disease, histopathological review not only grades the severity of steatosis but it allows differentiation between steatosis and steatohepatitis. Steatohepatitis is associated with less favourable outcomes following hepatectomy. Data from the Fibroscan technique (or its equivalent) are controversial in detecting steatosis and evaluating fibrosis in asymptomatic healthy individuals and, as yet, cannot replace the traditional algorithm of ultrasound and biopsy. Expert hepatology review should be available to interpret and respond to the findings. To date more than 100 alleles have been identified, only some of which are associated with liver disease. If the liver screen of the potential donor reveals a low alpha-1 antitrypsin level, phenotyping and genotyping are recommended. Such phenotypes therefore should not be disregarded but assessed further with a liver biopsy to look for evidence of underlying liver disease, especially if there are other co-factors for liver disease (18-19). Liver biopsy is then recommended if there is concern about the potential for liver disease in the donor (19). Infections can be transmitted by organ donation during the incubation period of the offending organism and before a serological response has been mounted. Serology is therefore not a substitute for a detailed psychosexual and medical history. Routine testing for viral infection may, if positive, raise complex ethical problems. Advice from a hepatologist must be sought under these circumstances and the donor and recipient kept fully informed (27). Consideration must be given to the prophylactic use of antiviral agents in order to minimise viral load after transplantation, although the benefit of this approach is unclear (28). There must be active screening for Mycobacterium tuberculosis and atypical mycobacteria.

We are primarily holographic $elds of energy and information medications you can take when pregnant purchase discount brahmi on line, and secondly physical treatment 4 sore throat cheap 60caps brahmi visa. As Above symptoms of colon cancer cheap 60 caps brahmi free shipping, So Below In our current understanding of the universe medicine definition generic brahmi 60 caps fast delivery, there are two main sets of particles: matter particles called fermions (quarks and leptons) and force carrying particles called bosons (photons treatment internal hemorrhoids purchase genuine brahmi online, gluons, gravitons, etc. Quarks are the building blocks of protons and neutrons, which make up the nucleus of an atom, and the most common lepton, the electron, surrounds the nucleus. Photons are the most notable boson or force-carrying particle, and are responsible for the entire electromagnetic spectrum. Most of the rest of the 4% of our weight is from Calcium, Phosphorus, Potassium, Sulfur, Sodium, Chloride, and Magnesium. We get these elements from the food we eat, the water we drink, and the air we breathe. We know the body has a detectable energetic $eld of up to 15 feet, we know the body emits and communicates via a complex and vast biological photon network, called biophotons. Just like the physical body is made of matter particles, this energetic body is made of force carrying particles (mainly the photon) and requires these just as the body needs food, water, and oxygen. Ask yourself a question, when you think of the word geology? does the notion of a life science come to mind? Not only that, but the $elds of the earth are much more complex and dynamic than the simple bar magnet analogy incorrectly portrays. In fact these pulsating electromagnetic $elds of energy and information are the 5th element of health. We?ll begin by taking a brief look at a theory that resurrects earth back into living status. He mentions how much life is imbedded in planetary and cosmic connections and how central the in"uence of the sun and earth is on all life. According to the Gaia theory (named after the Greek goddess of the land) proposed by James Lovelock, the earth is in its totality, one super organism, which can self-regulate. Overall, the Gaia theory is a compelling new way of understanding life on our planet. It claims we?re more than just the third rock from the sun, situated precariously between freezing and burning up. More and more evidence is supporting that the Gaian system? self-regulates global temperature, atmospheric content, ocean salinity, and other factors in an intelligent manner. In this theory, the earth can be likened to an individual organism that intelligently self-regulates just like we have shown our human body self-regulates temperature, pH, oxygen levels, blood salinity, etc. If you viewed the earth from space, you would know instantly that the earth was alive. Photosynthetic algae began extracting the carbon dioxide from the atmosphere and releasing life-supporting oxygen over 2. Venus and Mars lay exposed and bare to harsh solar winds, "ares, and radiation of the sun, while our earth has a very protective and nurturing shield. Remember our bodies have an energetic $eld analogous to the earths, which gives us life! Having a magnetic $eld is essential for life in its protecting and nourishing capabilities. We have evolved and "ourished on this planet, and perhaps take for granted that we?re surrounded by Life itself. We?ll now take a closer look at the magnetic and pulsed magnetic $elds of the earth. We?ll see the earth is more than an inert ball of stone, and does not resemble a big spherical bar magnet. We need to look upon the earth through the fresh eyes of quantum $eld theory, viewing it primarily as a $eld of energy and information. Along with chemistry, medicine, and biology, the science of geology needs to be upgraded to the new paradigm of quantum $eld theory! According to the dynamo theory, electric currents in the liquid outer core generate the magnetic $eld of the earth. Another feature that distinguishes the earth magnetically from a bar magnet is its magnetosphere. At large distances from the planet (beyond the ionosphere) this magnetosphere dominates the surface magnetic $eld. Magnetism is de$ned by a moving charge (usually an electron) and you can create a near perfect replica of the magnetic $eld lines around a bar magnet with a current loop (see image below). If a current loop is used, the magnetic $eld lines will yield a very pure $eld in the center of the loop, as if a bar magnet were being used. Although intensity is important, frequency is the key to health and synchronization of our bodies with the earth. Frequency is a carrier of both energy (E = hv) and information (interference patterns, phase relations, holograms, etc. Frequency describes the number of waves (or cycles) that pass a $xed place in any given amount of time. If 10 waves pass through a $xed point in one second, the frequency would be 10 cycles/second or 10 Hz. Usually frequency is measured in the hertz unit, named in honor of the 19th-century German physicist Heinrich Rudolf Hertz. For example, an A? note on a violin string vibrates at 440 Hz (440 vibrations per second). Frequency is an abstract mathematical concept that applies to many physical phenomenon. If there are a large number of waves in a compact area that would be considered a high frequency, relative to a small number of waves. A low frequency sound wave is your bass or low tones, whereas a high frequency sound is the treble or high pitch. On an interesting side-note, the human ear can pick up frequencies from around 20 Hz 20,000 Hz (20 cycles per second to 20,000). All forces of energy and power associated with electricity and magnetism comes from the photon. It makes up all visible light, radio waves, infrared waves, x-rays, gamma rays, and everything in between. Notice how only a small portion of the electromagnetic spectrum is visible to the human eye. Infrared and ultraviolet are also present, as evidenced in the warmth we feel from the sun (infrared) and the sunburn we can experience from ultraviolet. Equally important for life, are the geomagnetic and Schumann resonance frequencies. Meyers are approximately scalar waves (standing waves), which means they are more primary and fundamental then simple electromagnetic waves. Just as a tuning fork has resonant frequencies for sound, so does the earth and the ionosphere surrounding it have resonance frequencies for electromagnetic radiation called the Schumann resonance. Contrary to New Age discussions, the fundamental Schumann resonance is not rising. We?ll see in the next section that this 0-30 Hz range of frequencies are the most important for our body, mind, and cells. As we saw in chapter four, scalar and vector potentials are causal to and more fundamental than electromagnetic waves as carriers 97 Bryant a. We all march to the cadence of this cosmic drummer our planetary heartbeat, which sets the tempo for our health and well-being. If you look at a compass under high magni$cation, you will see that it vibrates and "uctuates. When you measure underground you use di#erence measurements to separate what is measured above and below; but remember both must be in balance (Remember $gure 4 from chapter 1). Lower Frequencies of the Earth Completing the 0-30 Hz Range We saw the primary harmonic frequencies of the Schumann resonances and geomagnetic frequencies were between 7-30 Hz. So what about the lower frequencies from 0-7 Hz, which are a vital spectrum of frequencies as well, such as the delta and theta brain wave frequencies. Meyers Here are some natural frequencies of di#erent radii on the earth, moon, and sun that seem to correspond to the delta and theta waves of the human brain that perhaps may explain why we operate at these lower frequency also2. We hear a lot about the body-mind connection in alternative medicine, when in actuality it is not the whole picture as it lacks the key element earth. Remember our holographic energy body is an open system connecting upwards from the earth and cosmos and downwards to the organs, tissues, cells and atoms. It more than sustains, protects and nourishes all your organ systems, tissues, and cells. Very simply, health is a state of being connected to the earth, its $elds and all the elements needed for life, while ill health is a mirrored state of being disconnected. First, the frequencies that the earth emits through both the Schumann and geomagnetic frequencies (along with the higher harmonics or octaves) are primarily in the 0-30 Hz range. Secondly; Sisken and Walker proved that the tissues in our body resonate primarily to the frequency range of 0-30 Hz. Later Japanese researcher Seto con$rmed this result independently with master Chi Kung practitioners. It was obvious; the earth emits precisely the right intensity and frequency at the exact time we need it! Frequencies the Cells Resonate to and Absorb (0-30Hz) Beginning in the mid-70s, W. Outside of these ranges or windows?; however, there was no response or minimal at best. Research has shown that biological systems defy the seemingly obvious logic that a larger stimulus should produce a larger e#ect. Meyers weak and even extremely weak $elds can have very potent and powerful e#ects, while strong $elds may have little or no e#ect (or even be harmful). So not only is there a frequency window, but there is an intensity window as well which again are the intensities the earth gives us. Figure 18 lists frequencies in the 0-30 Hz that biomedical researchers are $nding e#ective for the healing of soft and hard tissues. Frequencies of 10Hz promotes ligament healing, and 15, 20, and 72Hz may be used to decrease skin necrosis and stimulate capillary formation. Since tissues and organs are made of cells, this5 research further con$rms the hypothesis the human body needs, resonates and responds to the 0-30 Hz range of frequencies. Zimmerman discovered that a pulsating biomagnetic $eld emanated from the hands of therapeutic touch practitioners. Seto and colleagues, in Japan, studied practitioners of various martial arts and other healing methods. Biological Entrainment Understanding the 0-30 Hz Connection To better understand this body-mind-earth connection, it is helpful to introduce the principle in physics called entrainment. Physicists use the word entrainment to describe a situation in which two rhythms that have nearly the same frequency become coupled to each other so that both end up with the same frequency. Christian Huygens, an important physicist, coined the term entrainment when he noticed two pendulum clocks close together had begun swinging to the same rhythm. In living systems there are many examples of entrainment; for instance crickets chirp in unison and $re"ies "ash at the same time. Our bodies are entrained to various light/ dark, temperature, lunar, and solar cycles. Meyers When a musician has an audience captivated, they have them entrained into the rhythm of the music. If you have ever mediated in a group, you feel an increased strength of the meditative experience, which is a subtler form of entrainment. Most important to our discussion is the body, mind and cellular entrainment with the frequencies of the earth as depicted in $gure 16. We have introduced how the earth, body, brain and cells function primarily in 0-30 Hz range. Research has shown that in addition to the brain and pineal gland, magnetite is actually found in most tissues of the human body8. Magnetite is the only known metallic compound made by living organisms and has the highest electrical conductivity of any biochemical compounds in the human body. Although the total amount of magnetite in an adult human is small (a few hundred micrograms), it interacts very strongly with external magnetic $elds. In fact, these magnetic crystals are more than a million times more responsive to external magnetic $elds than surrounding cellular non-magnetic structures. Magnetite is also found in areas of the brain and tissues of insects, $sh, birds and mammals. As an amazing example, some monarch butter"ies are known to "y from Nova Scotia, Canada to the mountains of Mexico City, some 3000 miles (5000 kilometers) away. Not only do they "y to the same region as their forefathers, but also each one often returns to the very same tree! Back to the human body, studies by Kirschvink and others have shown that bio-magnetite can act as a transducer, which means it can convert one form of energy to another. Fact Supplemental Magnetite is used in Traditional Chinese Medicine to calm the mind, improve vision and hearing, and strengthens the kidneys to improve the acceptance of chi energy. Magnetite also helps to relieve vertigo and dizziness by improving balance, dyspnea (shortness of breath), asthma and palpitations (irregular heartbeats). Our brains operate within the 0-30 Hz range and our tissues (Sisken and Walker) and cells (Adey and Bawin Research) require frequencies in this range as well.
