Vascular Dementia
Vascular dementia is dementia caused by a series of strokes. Restricted blood flow due to strokes reduces oxygen and glucose delivery to the brain, causing cell injury and neurological deficits in the affected region. Subtypes of vascular dementia include subcortical vascular dementia, multi-infarct dementia, stroke-related dementia, and mixed dementia. Subcortical vascular dementia occurs from damage to small blood vessels in the brain. Multi-infarct dementia results from a series of small strokes affecting several brain regions. Stroke-related dementia involving successive small strokes causes a more gradual decline in cognition. Dementia may occur when neurodegenerative and cerebrovascular pathologies are mixed, as in susceptible elderly people (75 years and older). Cognitive decline can be traced back to occurrence of successive strokes. ICD-11 lists vascular dementia as ''dementia due to cerebrovascular disease''. DSM-5 lists vascular dementia as either ''major or mild vas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertebral Artery Dissection
Vertebral artery dissection (VAD) is a flap-like tear of the inner lining of the vertebral artery, which is located in the neck and supplies blood to the brain. After the tear, blood enters the arterial wall and forms a blood clot, thickening the artery wall and often impeding blood flow. The symptoms of vertebral artery dissection include head and neck pain and intermittent or permanent stroke symptoms such as difficulty speaking, impaired coordination, and visual loss. It is usually diagnosed with a contrast-enhanced CT or MRI scan. Vertebral dissection may occur after physical trauma to the neck, such as a blunt injury (e.g. traffic collision) or strangulation, or after sudden neck movements (e.g. coughing), but may also happen spontaneously. 1–4% of spontaneous cases have a clear underlying connective tissue disorder affecting the blood vessels. Treatment is usually with either antiplatelet drugs such as aspirin or with anticoagulants such as heparin or warfarin. Ve ...

Ventricular Assist Device
A ventricular assist device (VAD) is an electromechanics, electromechanical device that provides support for cardiac pump function, which is used either to partially or to completely replace the function of a failing heart. VADs can be used in patients with acute (sudden onset) or chronic (long standing) heart failure, which can occur due to coronary artery disease, atrial fibrillation, valvular disease, and other conditions. Categorization of VADs VADs may be used to manage a variety of cardiac diseases and can be categorized based on which ventricle the device is assisting, and whether the VAD will be temporary or permanent. Ventricular Assistance First, VADs can be categorized based on whether they are designed to assist the right ventricle (heart), ventricle (RVAD) or the left ventricle (LVAD) or to both ventricles (BiVAD). The type of VAD implanted depends on the type of underlying heart disease (e.g. patients with right ventricular failure from pulmonary arterial hyperten ...

Vitamin A Deficiency
Vitamin A deficiency (VAD) or hypovitaminosis A is a lack of vitamin A in blood and tissues. It is common in poorer countries, especially among children and women of reproductive age, but is rarely seen in more developed countries. Vitamin A plays a major role in phototransduction, so this deficiency impairs vision, often presenting with nyctalopia (night blindness). In more severe VAD cases, it can progress to xerophthalmia, keratomalacia, and complete blindness. Vitamin A deficiency is the leading cause of preventable childhood blindness worldwide and is a major cause of childhood mortality. Each year, approximately 250,000 to 500,000 malnourished children in the developing world go blind from a VAD, with about half of whom dying within a year of losing their sight. Addressing VAD has been a critical focus of global health initiatives, including Sustainable Development Goal 2: to end hunger, achieve food security and improved nutrition and promote sustainable agriculture. ...

Chemotherapy Regimen
A chemotherapy regimen is a regimen for chemotherapy, defining the drugs to be used, their dosage, the frequency and duration of treatments, and other considerations. In modern oncology, many regimens combine several chemotherapy drugs in combination chemotherapy. The majority of drugs used in cancer chemotherapy are cytostatic, many via cytotoxicity. A fundamental philosophy of medical oncology, including combination chemotherapy, is that different drugs work through different mechanisms, and that the results of using multiple drugs will be synergistic to some extent. Because they have different dose-limiting adverse effects, they can be given together at full doses in chemotherapy regimens. The first successful combination chemotherapy was MOPP, introduced in 1963 for lymphomas. The term " induction regimen" refers to a chemotherapy regimen used for the initial treatment of a disease. A " maintenance regimen" refers to the ongoing use of chemotherapy to reduce the cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assisted Dying (other)
Assisted dying (sometimes referred to as assisted death, aid in dying, medical aid in dying or help to die) has been defined as the involvement of healthcare professionals in the provision of lethal drugs intended to end a patient’s life, subject to eligibility criteria and safeguards. It can include * Assisted suicide, the practice of helping or assisting another person to end their life. * Euthanasia, the practice of otherwise intentionally ending someone's life to relieve pain and suffering. * Palliative sedation may in some cases accelerate the death of the patient, so sometimes it is also considered an assisted death. See also * Right to die * Dignified death *Assisted dying in Australia *Voluntary assisted dying in Western Australia *Euthanasia in Canada *Euthanasia in the Netherlands *Euthanasia in New Zealand *Euthanasia in Switzerland *Assisted suicide in the United Kingdom *Euthanasia in the United Kingdom *Assisted suicide in the United States *Euthanasia in the ...

Voluntary Aid Detachment
The Voluntary Aid Detachment (VAD) was a voluntary unit of civilians providing nursing care for military personnel in the United Kingdom and various other countries in the British Empire. The most important periods of operation for these units were during World War I and World War II. Although VADs were intimately bound up in the war effort, they were not military nurses, as they were not under the control of the military, unlike the Queen Alexandra's Royal Army Nursing Corps, the Princess Mary's Royal Air Force Nursing Service, and the Queen Alexandra's Royal Naval Nursing Service. The VAD nurses worked in field hospitals, i.e., close to the battlefield, and in longer-term places of recuperation back in Britain. World War I The VAD system was founded in 1909 with the help of the British Red Cross and Order of Saint John (chartered 1888), Order of St John. By the summer of 1914 there were over 2,500 Voluntary Aid Detachments in Britain. Of the 74,000 VAD members in 1914, two-third ...

Voice Activity Detection
Voice activity detection (VAD), also known as speech activity detection or speech detection, is the detection of the presence or absence of human speech, used in speech processing. The main uses of VAD are in speaker diarization, speech coding and speech recognition. It can facilitate speech processing, and can also be used to deactivate some processes during non-speech section of an audio session: it can avoid unnecessary coding/transmission of silence packets in Voice over Internet Protocol (VoIP) applications, saving on computation and on network bandwidth. VAD is an important enabling technology for a variety of speech-based applications. Therefore, various VAD algorithms have been developed that provide varying features and compromises between latency, sensitivity, accuracy and computational cost. Some VAD algorithms also provide further analysis, for example whether the speech is voiced, unvoiced or sustained. Voice activity detection is usually independent of language. ...

Interactive Voice Response
Interactive voice response (IVR) is a technology that allows telephone users to interact with a computer-operated telephone system through the use of voice and DTMF tones input with a keypad. In telephony, IVR allows customers to interact with a company's host system via a telephone keypad or by speech recognition, after which services can be inquired about through the IVR dialogue. IVR systems can respond with pre-recorded or dynamically generated audio to further direct users on how to proceed. IVR systems deployed in the network are sized to handle large call volumes and also used for outbound calling as IVR systems are more intelligent than many predictive dialer systems. IVR systems can be used to create self-service solutions for mobile purchases, banking payments, services, retail orders, utilities, travel information and weather conditions. In combination with systems such an automated attendant and automatic call distributor (ACD), call routing can be optimized for a ...

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
