Lesson 3. Palliative Care 部突破! いま最もアツく、最もイカ Medical treatment / Health STEP P 1 Read the Article Let's learn about palliative care, medical care that relieves pain, symptoms and stress caused by serious illness. 1) Palliative care, form of health care that seeks to improve the quality of life of patients with terminal disease through the prevention and relief of suffering. It is facilitated by the early identification of life-threatening disease and by the treatment of pain and disease- associated problems, including those that are physical, psychological, social, or spiritual in nature. As defined, palliative care begins at the point of diagnosis of terminal disease and can be delivered in a variety of health care settings. In general, it involves health and social care professionals working in hospitals, communities, hospices, and voluntary sectors. 2) Palliative care has been associated with many different terms, including terminal care, care of the dying, end-of-life care, and supportive care. However, these forms of care are not necessarily the same as palliative care. Likewise, palliative care is also sometimes described as hospice care. While hospice care does imply palliative care, it is specific to care provided near the end of life. In contrast, palliative care covers the duration of a patient's illness and, hence, may be delivered over the course of years. 3) Palliative care emphasizes three main principles: 1) A team-based approach is fundamental in managing distressing symptoms, such as pain, nausea, fatigue, and depression. It is also a necessary component in meeting the physical and psychosocial needs of the patient and his or her family. 2) Dying is a normal process. Symptom management is needed in order to help patients live life to the fullest until they die. 3) The synthesis of physical care with psychological and spiritual care fulfills a vital role in the overall care of the patient. 4) Palliative care is a global concern, and a steady rise in the number of people who are living longer with degenerative disease suggests that demand for palliative care services will increase in the are areas of intense. developments such Standards Framewo and Palliative Care Indian Association health care profes intended to help physical and psyc 5) In some place For example, the and has identifie framework is int days of life.

赤い印のところがわかりません。 logxをxで微分したらx'/xになるのはわかるのですがlogyをxで微分してもy'/yになるのはなぜですか?logyにxは入っていないので0になると思ったのですが、、、
