Medical is the science and practice of caring for a person with an illness or injury, managing their diagnosis, prognosis, treatment and prevention. It is a discipline that uses evidence-based practice and promotes health by optimizing treatment outcomes, quality of life and wellbeing. Medical care can be provided by physicians, nurses and other allied health professionals, as well as by health care support workers. Medicine is a broad term that includes a variety of specialties, such as pharmacology (the study of drugs), clinical physiology (the study of the body’s normal functions), public health, primary care, infectious disease, medical imaging, and surgery. Some of these specialties focus on particular organ systems, for example cardiology (the study of the heart), hematology (the blood and its disorders) or pulmonology (the lung). Others, such as medical physics, microbiology, molecular biology, and neuroscience, have more general applications to human medicine. Historically, the practice of medicine was a combination of art and science, with many early Western traditions influenced by religious and philosophical beliefs such as herbalism or the ancient Greek theory of humorism. In modern times, scientific biomedical research has replaced much of the earlier tradition, although some practices based on traditional beliefs persist, such as using bloodletting or certain herbal remedies. In most countries, it is a legal requirement for doctors to be trained in evidence-based medicine, or at least be registered with a national medical board that ensures they have undergone appropriate training and examinations. This is intended to limit the ability of charlatans to practice unproven treatments, and to provide a guarantee to patients that their doctor has undergone proper training. Most people rely on their doctors to make decisions about their healthcare, but it is important for them to understand their own healthcare choices as well. This can include what treatments are available, the benefits and risks of each option, and how a decision might affect their lifestyle or cost. It is also vital for them to be aware of any potential side effects from a treatment, and to consider the impact of their choice on family members and colleagues. While medical terminology is often viewed as difficult to learn, it is actually a logical system of classification that can be broken down into its component parts: prefix, root and suffix. This helps to simplify the way that medical terms are pronounced and understood, and it reduces confusion when communicating with different healthcare professionals. Understanding medical terminology can help to ensure that people get the best possible care, by ensuring that all parties involved are speaking the same language. This is particularly important when communication between doctors and other healthcare professionals is required, but it can be beneficial for all individuals who come into contact with the health care system. In fact, medical terminology is a prerequisite for most degree programs in the field of healthcare.
Read MoreIn 1948 Mahatma Gandhi validated the idea that health is wealth, a belief that is rooted in the notion that a person cannot fully realize their potential and serve society without good health. Despite this, the concept of health has been a subject of much debate and is difficult to define. Moreover, there are many different definitions of health that vary depending on the context of an individual’s life and their underlying beliefs and values. For example, for an athlete health may be defined as the ability to complete a 5000m race or for an economist it could be the profitability of a business. The old English word for “health” is haelth and this suggests our ancestors understood that health is connected to a person’s well-being. It is therefore not surprising that, for centuries, health has been viewed as an integrated whole of the mind and body. For this reason, many people are interested in achieving the highest level of health possible given their circumstances. Historically, the notion of health has been influenced by cultural, religious and social factors. Early philosophers, like Democritus and Hippocrates, linked health to physical survival and believed that the health of an organism was directly related to its environment. Other ancient traditions associated health with spirituality and saw healing as a process of restoring balance to the world. As scientific advances have shifted our understanding of the nature of disease, so too has our thinking about health. During the 1980s, the WHO fostered the development of the health promotion movement which promoted a view of health as not just an absence of disease or infirmity but as a dynamic process of resiliency that enables a person to live their lives to the fullest. This definition was influenced by the work of Canguilhem and promoted a concept of health as “a resource for living”. For some, this broader perspective on health is more relevant than ever in 2020. As the COVID-19 pandemic demonstrates, we live in a globalized world where maintaining health requires the capacity to adapt and self-manage in response to changing contexts that threaten physical, emotional and social wellbeing. When writing about a topic of Health, consider the format you are producing – a short news story, an in-depth feature article or a profile of a researcher investigating a new treatment. Each of these formats require a different approach and will have a bearing on how you frame your idea. Identifying your audience will help you decide what information is appropriate for each of these formats and how best to present it. For example, you might want to use tables or figures to clearly present a lot of complex information that would be difficult to include in text. Using visuals can also make your article more accessible for people who may be reading with impaired vision. Lastly, use an active voice when constructing your article as this will clarify and simplify the reading experience for your readers.
Read MorePharmacy is the science and practice of discovering, producing, preparing, dispensing, reviewing and monitoring medications, aiming to ensure the safe, effective and affordable use of medicines. It is a miscellaneous science as it links health sciences with pharmaceutical sciences and natural sciences. If you want to become a pharmacist, then you need to get an education from a reputable college that is approved by your state board of pharmacy. You also have to pass the North American Pharmacist Licensure Examination (NAPLEX) and Multistate Pharmacy Jurisprudence Examination (MPJE). In addition to filling prescriptions, pharmacists also do a variety of other tasks. These may include verifying that a patient’s new prescription will not interfere with any other medication he or she is taking, instructing patients on how to take their medicine, and informing them about the possible side effects. Other responsibilities include keeping meticulous records, coordinating with insurance companies, and supervising pharmacy technicians. The demand for pharmacists is expected to continue to grow as people live longer and require more medical treatments. As a result, more people are considering this career. It is important to consider all of the benefits and drawbacks before pursuing this type of job. Pharmacy is a rewarding profession, but it’s also an extremely competitive one. Many pharmacists find that it’s difficult to obtain a good-paying job right out of school. This is because there are more applicants for these positions than there are available jobs. Fortunately, there are ways that pharmacists can improve their employment prospects. A career in pharmacy is a great choice for people who enjoy helping others. This is because pharmacy is a service-based profession and people always need help with their health problems. In addition, there is a wide variety of medications that are available to treat different health conditions. A career in pharmacy is a great choice because it offers a high salary and good benefits. If you are thinking about becoming a pharmacist, then you should start by assessing your personal qualities. This will help you decide if it is the right profession for you. For example, you should think about whether or not you have good communication skills and if you can work well under pressure. Also, you should think about your personal interests and decide if they are related to pharmacy.

Read MoreCancer is a disease that starts in one or more types of cells and grows out of control. It is a large group of diseases with many different kinds of tumors, each with its own characteristics and behavior. Depending on the type of cancer, it can affect different parts of the body and cause many health problems. Cancer can be treated by surgery, radiation therapy, chemotherapy, or other medicines. Researchers are studying ways to prevent cancer and ways to cure it. When cancer starts, cells divide more often than normal cells and don’t die when they should. As a result, the number of cancer cells quickly grows and they can outnumber healthy cells. Cancerous cells can also grow and spread to other areas of the body. Some types of cancer can be more serious than others. Scientists believe that cancer is caused by changes (mutations) in the genes. Some mutations are inherited from parents, while others happen when cells divide. Mutations can also be caused by things in the environment, such as tobacco smoke and sunlight. Mutations can change how cells respond to signals that control cell growth and death. They can also change how cells make energy from nutrients. There are two main types of cancer: solid tumors, which start in cells that line tissues like the skin and lungs, and blood cancers, which start in blood-forming cells, such as those in the bone marrow. Each cancer is named after the tissue where it starts, or the cell type from which it originates. The first step in cancer development is a series of mutations in genes, called oncogenic mutations. These mutations can lead to a series of events that give the cancer its distinctive features. These mutations can make cells grow and divide too much, or they can ignore signals that stop cell growth or tell cells to die (programmed cell death). They can also evade the body’s controls on blood vessels that supply tumors with oxygen and nutrients or remove waste from them. Cancers can also trick the immune system into helping them stay alive and grow. Scientists now know that all cancers start in one or more cells and grow out of control. They also know that the earliest stages of cancer, when it is still very small and limited to a single area of the body, are similar for all cancers. In a few years, improvements in screening and treatments will likely help reduce the number of new cases of cancer and the number of deaths from cancer. However, some people will always develop cancer. Researchers are trying to find ways to stop new cancers from starting, especially in young people. They are examining things that can increase the chance of cancer, such as smoking and exposure to UV rays, and things that protect against cancer, such as good diet, exercise, and avoiding infections.
Read MoreMedical is a wide field that encompasses the study of human health and diseases, medical procedures and treatments, and underlying sciences such as anatomy, chemistry, and biology. There are also specialized fields, such as pharmacology and radiology, that deal with specific parts of the body or aspects of disease and treatment. Generally, medical professionals focus on one or more of these areas. Modern medicine is based on scientific research, but it also relies on traditional knowledge and common sense. It is a field that constantly evolves, with new discoveries and improvements in technology driving changes. This is especially true of the molecular and genetic aspects of medicine, which have radically altered the way diseases are viewed and treated. Throughout history, people have found medicinal properties in plants and used them to cure illnesses. This initial trial-and-error approach to healing eventually evolved into purposeful scientific study of medicines and conditions. The rise of the 19th century brought many new advancements to healthcare, including anesthesia, syringes, antiseptics, x-rays, and penicillin. This led to the development of modern medical practices and procedures, as well as the emergence of medical insurance and administration. A medical history — also known as an anamnesis — is a series of health-related questions that a physician or nurse asks a patient during a visit. The goal of a medical history is to collect reliable and objective information that will lead to a medical diagnosis and effective medical treatments. Medical terminology is the language that medical professionals use to describe anatomical structures, processes, and conditions. Although it may seem intimidating at first, medical terminology is surprisingly easy to learn. Like most languages, it adheres to a simple structure of word parts, such as prefix, root, suffix, and combining vowel, that allow physicians and nurses to build up a vocabulary of thousands of terms. Root words are intuitive for most, such as “cardiovascular,” which relates to the heart and arteries; or “dermatologic,” which describes the skin. Suffixes, which are added to the end of a root word, are often derived from Latin or Greek and indicate location, direction, or type. A basic understanding of medical terms is critical for many different careers in the healthcare industry. This includes aspiring doctors, nurses, physician assistants, physical or occupational therapists, and veterinary technicians. It is also important for medical receptionists and health insurance agents. A knowledge of medical terminology is also helpful for anyone who has to interact with these medical professionals, as it allows them to communicate clearly and effectively. Medical courses are available at most colleges and universities, as well as through continuing education programs, trade schools, and adult education programs. The University of San Diego, for example, offers an online Medical Terminology course that students can take at their own pace and work through in six months. The course is a great way to earn continuing education credits, too.
Read MoreHealth refers to the state of a person’s physical and mental well-being. It is often defined as the absence of disease and infirmity, but it can also be viewed as a more holistic concept. The Zagreb Andrija Stampar School of Public Health defines health as “a resource for life and a function in society.” A healthy lifestyle is important for maintaining good health. A person’s genetic make-up can have a big impact on their health, but many other factors contribute to a person’s level of fitness and wellness. A person’s diet, exercise, stress levels and sleeping patterns all play a role in their overall health. The environment, which includes climate, work and social relationships, also influences a person’s health. People’s ability to adapt to change in their environment is a critical factor in determining their level of health. Different people have different ideas about what constitutes good health. For example, a competitive swimmer with Down syndrome who feels fully functional and happy may consider themselves to be in good health, while a high school teacher with bipolar disorder may feel the opposite. It is important for health professionals to be aware of the diverse opinions about what constitutes good health, and to try to reach a consensus on a definition that can be applied consistently in practice. The World Health Organization (WHO) coined a widely accepted definition of health in 1948. This definition stated that health is a “state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” The WHO’s 1948 definition expanded on earlier conceptualizations of health by including the concepts of mental and social well-being. When writing about Health, it is important to consider the format of your article. Will it be a short news story, an in-depth feature article or a profile of a scientist researching a new treatment? The choice of format will help you focus your idea and determine how much detail to include. It is also helpful to follow scientific research on the topic that you are writing about. Signing up for email alerts from your favorite scientific journals can keep you up-to-date on the latest discoveries, and may inspire new health articles. Also, keeping abreast of the work done by alternate medicine therapists and doctors who specialize in a certain condition can also generate ideas for health articles. Remember to write objectively when covering sensitive topics such as alternative medicine. This will ensure that the reader is not influenced emotionally and can form his or her own opinion about the subject matter. It is also important to cite any sources of information that you use in your articles. This will help maintain the integrity of your work and prevent other scientists from misquoting or misunderstanding your conclusions. Also, do not take a biased approach to an issue because it can lead to faulty and inaccurate information in your health articles. This can confuse or irritate the reader, and it could damage your reputation as a writer.
Read MorePharmacy is a profession that involves the discovery, production and dispensing of medicines. It is a knowledge-based discipline with both theoretical and practical components. It is also a multi-disciplinary science that crosses health sciences with pharmaceutical and natural sciences. A pharmacist is a health care professional who provides medicine advice and fills prescriptions written by doctors. Pharmacists are specially trained to explain the purpose and use of drugs and can answer questions about side effects. They also help with adherence to drug regimens. Pharmacists may work in pharmacies, clinics, hospitals, medical research laboratories and universities. In most countries, to practice as a pharmacist, you need a degree from a college of pharmacy and a license to practice. This is usually granted by a government agency. In addition to specialized education in pharmacy, pharmacists must continue to learn through professional development courses and seminars. This allows them to stay current on the latest advances in pharmacological science and their application in daily practice. The profession of pharmacy has a long history, dating back thousands of years. It was originally a separate practice from that of a physician. The earliest pharmacists were herbalists and supplied physicians with the raw materials needed to prepare medicinal compounds. Later, Benjamin Franklin helped to separate the duties of a physician and those of an apothecary. In today’s world, the responsibilities of the pharmacist are vast and varied. There are essentially four different aspects of pharmacy practice, each with its own unique disciplinary background and focus: Pharmaceutical science is the scientific study of medications, including how they work and what they do in the body. It is a multi-disciplinary field that includes such subjects as chemistry, biology, physics and physiology. A basic five-year curriculum at a pharmacy school includes these disciplines as well as pharmacology, physiology and medical terminology. Clinical pharmacy focuses on the care of individual patients. It is a patient-centred and evidence-based approach to pharmaceutical care that incorporates health promotion and disease prevention. It is a patient-oriented and client-focused aspect of pharmacy that requires excellent interpersonal skills. Industrial pharmacy entails the research, production, packaging, quality control and marketing of pharmaceutical products. It is a multi-disciplinary field encompassing such areas as pharmacology, chemistry, biology, physiology and statistics. This article is designed to expose the confusion and fragmentation that exists in the dialogue around defining the term “pharmacy”. It is an attempt to initiate discussion to increase clarity, or at least begin the process of unification. This should allow policy makers and educators to develop policy interventions that are consistent within, and across, the pharmacy sector nationally, regionally and internationally. This will help to unify the sector and enable it to better contribute to the achievement of global health goals. This will in turn lead to improved outcomes for patients. The need for this model has been highlighted by a number of factors, among which are: the fact that discipline labels mean different things to different people; the upward trend of clinical pharmacy and other sub-disciplines; and passionate and motivated drivers for the various sub-disciplines.
Read MoreCancer is a disease that starts in cells. Cells are the basic building blocks of our bodies and make up tissues and organs. Cancer forms when cells grow out of control and spread into surrounding tissue. This process is called metastasis. Cancer can affect almost any part of the body. There are more than 100 types of cancer and each type has its own set of signs and symptoms. All cancers start when some cells become abnormal and start growing out of control. Most cancers start in the skin or in blood vessels but can form in any cell in the body. Some cancers are more likely to form in specific parts of the body, like the lungs or bowel. The five most common cancers are lung, breast, prostate, bladder and colorectal. There are many reasons why normal cells may change and develop into cancer. Some of these changes are caused by things we can avoid, such as smoking or overexposure to sunlight. Other causes are related to things we can’t avoid, such as the viruses that cause hepatitis B, hepatitis C or human papillomavirus infection, or by certain chemicals or environmental toxins. Most cancers start when abnormal cells start to grow and divide without stopping or dying as they should. These abnormal cells can also spread into nearby tissues and damage or destroy them. As the cancer continues to grow, it may form a lump or tumour. Cancer cells can also move to other parts of the body through the blood or lymphatic system. This process is called metastasis. The immune system is a group of cells and organs that work together to protect the body against infections and diseases. It’s made up of a network of cells and organs including the spleen, thymus, tonsils and lymph nodes in the neck. The lymphatic system consists of the ducts that run from the lymph nodes to the bloodstream and the blood vessels that carry fluid in between the tissues. A person’s chances of developing cancer are partly down to their genes and family history. But there are many other things that can increase the chance of developing cancer, such as smoking and a diet low in fruits and vegetables, being overweight or not enough physical activity, drinking alcohol, and exposure to ultraviolet radiation from sunlight or tanning beds. About 4 in 10 cancers are caused by preventable factors. Some cancers, such as leukaemia and some lymphoma, begin in blood cells and don’t form solid tumours. But most cancers start in cells that line blood vessels, muscles and other tissue throughout the body. Some cancers also form in the bone marrow, the soft spongy area inside most bones. These types of cancers are called non-solid tumours or hematologic cancers.
Read MoreMedical is the study or practice of health care, including disease prevention and treatment. There are many branches of medicine, some focused on specific organ systems or diseases, others addressing general well-being. Most of the fields are multidisciplinary, with some overlapping between specialties. The term “medical” can also refer to the body of knowledge that physicians acquire during their education and training, which is typically structured through a doctorate in medicine or medical science, abbreviated MD or MS (in the United States) or Doctor of Osteopathy (DO, unique to the United States). Medical professionals must know a great deal about biology and chemistry in order to diagnose and treat patients effectively. Other essential components of medical knowledge include physics, mathematics and statistics. Many terms have roots in Latin or ancient Greek, and are derived from words that mean “to heal.” In addition to the scientific terminology that healthcare professionals must learn, there is also a vocabulary of common medical terms that has become part of our everyday language. A good place to start learning these terms is a medical dictionary. During a medical encounter, a physician meets with a patient to assess their symptoms and history and to recommend treatment options. This visit is documented in the medical record. Generally, the patient’s presenting complaint is noted as the chief complaint or CC. Other information recorded includes the patient’s past medical history (PMH) and family history. A number of key developments have occurred in the development of medical thinking throughout the ages. For example, a significant shift took place in the 14th and 15th centuries as scientists like Galen and Vesalius improved upon or rejected many of the theories that had been passed down from the previous generation of medical practitioners. The medical field also incorporates many ethical concepts, such as respect for persons – the principle that patients and their families have the right to be treated with dignity. This is also reflected in the concept of informed consent, which ensures that a patient understands the nature of a proposed course of action and has the opportunity to ask questions before agreeing to it. Most medical specialties fit into one of two broad categories: internal medicine and surgery. The majority of subspecialties within internal medicine require a preliminary degree in medicine, and in the United Kingdom, this is demonstrated by a Membership of the Royal College of Physicians (MRCP). The specialty of neurology addresses disorders of the nervous system, while obstetrics and gynecology are concerned with childbirth and the female reproductive and associated organs. Pharmaceutical medicine is the field of medical science that deals with the discovery, research, development, evaluation, registration and monitoring of medicines. Physiotherapy and rehabilitation, or physiatry, is aimed at improving function after injury or illness. Addiction medicine focuses on addiction and psychotherapy. Aerospace medicine is a branch of medical sciences pertaining to aircraft and space flight. Other less traditional or newer branches of medicine include clinical pharmacology and forensic medicine.
