In the modern era, it has become clear that environmental surfaces can easily be contaminated with infectious and disease-causing agents, and hence, disinfection plays a vital role in minimizing or reducing the chances of spreading infections. Disinfection is a process that includes physical or chemical means to control or destroy the harmful microorganisms that cause infectious diseases. The process of disinfection can be categorized into three levels in terms of the efficacy of disinfection. The chemical disinfectants are mainly categorized as per their chemical properties. These have different modes of action to destroy microbes, which include denaturing lipids or proteins, rupturing the cell wall, alkylation, or oxidation.

World war II gave rise to many advances, including healthcare specialization. In 1948, now called the American Academy of Family Physicians created the first U.S. CME credit system, which required 150 hours of CME for re-election to the membership every three years. In 1968, the American Medical Association came out with its Physician Recognition Award Categories 1 and 2, followed in 1972 by the American Osteopathic Association establishing categories of credit. Then, in 1981, along came the Accreditation Council for CME, which was created by the other medical organizations to provide a form of professional self-regulation for now 2,000 accredited providers of CME.

The healthcare sector is undergoing rapid changes with technological advancements and scientific breakthroughs to provide quality healthcare at an affordable cost. As a part of this, healthcare is adopting new technologies and is undergoing a digital transformation. One of the leading areas under this transformation is digital pathology, which is the digitalization of pathological operations. Digital pathology has been in healthcare and research since the introduction of photographic plates. But as technology is advancing, the tools used for performing pathological operations digitally are also advancing, with improvements in accuracy, ease of use, and connectivity.

The growing prevalence of diabetes worldwide is accelerating the demand for selfmonitoring blood glucose devices and test strips. For instance, around 10% of people are suffering from diabetes related complications in the US. Diabetes has been identified as the seventh leading cause of death in the US as it is known to cause cardiovascular conditions such as heart attacks, stroke, and blood clots. Other complications associated with diabetes include kidney-related diseases and amputation of lower limbs. Therefore, regular monitoring of blood glucose levels by diabetic patients and undiagnosed individuals is critical in effectively managing this chronic condition.

Allergies or allergic diseases are caused due to hypersensitive reactions produced by the immune system to substances that are often considered harmless in general. Allergic diseases impact almost 20% of the global population. The prevalence of allergies is increasing with population, especially among children, opting to stay indoors. Hence, many researchers have started to refer to allergies as modern epidemic. This is mostly the case with food allergies that cause the highest anaphylaxis. Allergies occur when the body encounters specific substances and the immune system of the body recognizes it as a harmful substance. Such substances are termed as allergens. When allergen encounters the body through eyes, nose, skin, or ingestion, it produces an allergic response. Based on the mechanism followed during an allergic response, the allergic reactions are categorized as types I, II, III, and IV. The first three types of allergic reactions are caused by antibodies, whereas the type IV allergic reaction is caused by the lymphocytes.

The global commercial hand dryer market mainly includes two product segments: hot air and jet air hand dryers. Hot air dryers use the traditional technology of evaporating water to dry hands, whereas the jet drying system is capable of blowing the water away from the hands within a few seconds. Further, the hot air system has also undergone numerous technological advancements with due course of time. Taking demand into consideration, both products are widely popular among endusers. In the present scenario, the market is dominated by hot air hand dryers in terms of unit sales and revenue. However, jet air dryers accounted for almost the same revenue generation. One of the key reasons for this is the pricing difference between hot air and jet air dryers.

Nutrition is an essential part of life, and the need for nutrition is often amplified by acute or chronic illness. Several studies indicate an estimated 30% to 50% of patients hospitalized in the US show signs of malnutrition, which can occur due to an imbalanced diet, impaired digestion or absorption of nutrition, or other medical conditions when metabolic requirements exceed intake. Malnutrition is a global problem, and studies have indicated that 40% of hospitalized elderly patients in Canada and nearly 40% of hospitalized patients in Europe suffer from malnutrition, which, if left unmanaged, can worsen morbidity, mortality, and health complications, in addition to extending hospitalization.
