On 18th November 2016 World Health Organization announced that Zika virus (ZIKV) infection no longer represents a public health emergency of international
concern. However, ZIKV infection and associated consequences still represent a significant long-term problem for the public health, and
many aspects of this infection require clarification and large-scale sustained research. In this paper we present the current knowledge about the ZIKV
infection, its symptoms, consequences, as well as possible prevention methods.

Paper describes characteristics of behavioural addictions and prevention interventions that can be delivered in everyday physician practice. Specific focus
is on similarities between behavioural addictions and substance-related addictions. Article presents possibilities of risk factors recognition for developing
those addictions and mechanisms of their development that enables defining vulnerable groups in general population. Additionally article points out
health and social harms from those addictions and possible challenges in recognition of their risks and prevention delivery. Ways of delivering prevention
were described according to first, second and third-order prevention, with focus on most common types of addictions, including gambling, web-based
addictions and sex addiction.

Disorders of the immune system in patients with rheumatic diseases cause increased risk and severe course of infections. Infections affect the course
of rheumatic diseases, might cause severe complications and increase mortality. Safe and effective vaccinations are key to preventing many infections.
Vaccinations are often postponed or overlooked in patients with rheumatic diseases, both children and adults. The main concerns about the administration
of vaccines are connected with risk of a rheumatic disease exacerbation, uncertainty regarding induction of adequate immunity and risk of disseminated
infection.
The aim of this publication is to present current recommendations on vaccinations in rheumatic diseases based on the European League Against
Rheumatism (EULAR), the Polish National Vaccination Program (Program Szczepień Ochronnych, PSO) and the Advisory Committee on Immunization
Practices (ACIP). For practical reasons, the recommendations are divided into categories by activity of the disease, the intensity of immunosuppressive
therapy and the type of the recommended vaccinations.

Falls of older people (over 65) occur frequently and - due to the aging of the population - their number increases. According to scientific reports, over 40%
of falls result in serious injuries, especially fractures of the limbs and spine, as well as craniocerebral injuries with frequent complications from the respiratory
and circulatory system. Thus, the consequences of the falls of older people constitute a serious individual, social and economic problem.
These falls are conditioned by: health factors [most often impairment of many functions related to the aging process, amblyopia / blindness, neurological,
psychological and orthopedic diseases, balance disorders with dizziness and fainting (often vasogenic, due to dehydration, minerals and vitamins deficiencies,
maladjustment to age of medications, polypharmacy)] and environmental (eg, housing malfunction, bad lighting, etc.). Prophylaxis consists in predicting
the risk of falls and preventing such events by changing lifestyle, adapting rooms, using appropriate equipment and using rehabilitation exercises,
as well as ensuring proper environmental and medical care.

The population of older people in Europe is growing and the number of those with age-related chronic diseases and disabilities is rising. Aging has an impact
on eating skills, supply of nutrients and metabolism. Many older adults are affected by cardiovascular disease, gastrointestinal tract problems, diabetes,
cancer, obesity, malnutrition, mental health changes, loss of cognitive function and waning senses. Some of those diseases are influenced by dietary
factors. As lean body mass and basal metabolic rate in older population decline the energy requirements reduce. Higher intake (or supplementation) of
some essential nutrients is recommended (vitamin D, B12, B6, calcium and iron, dietary fiber, antioxidants, water). Well balanced diet and physical activity
appropriate to health status can improve quality of life, boost strength, slow down progress of existing chronic diseases and functional decline in elderly.
