AB  - Background: Although the use of medicinal plants have been known since ancient times, an increased use of herbal products is evident in the last few decades, mainly as a part of self-care treatments. In addition to the positive health effects, the use of herbal products can cause certain side effects as well as interactions with conventional therapy, especially among elderly patients.
Purpose: To examine the awareness, habits and attitudes of elderly patients towards the use of herbal products in the Republic of Serbia.
Method: The quantitative, non-experimental research was conducted using a questionnaire in public pharmacies during February 2020. Patients older than 60 years were included in the study. The study was anonymous, and patients gave informed consent.
Results: The study involved 436 patients, of whom 62.4% were female. Most of the respondents live in the city (72.9%) and have a high school or lower education degree (61.9%). Most patients (32.3%) use herbal products daily, while only 12.1% rarely or never use them. Every fourth patient (24.5%) uses them for treatment, while 69.5% to improve their health. Although the majority of patients purchase herbal products in pharmacies and in health food stores (53.6% and 20.8%, respectively), a significant number (19.3%) collect medicinal plants and prepare herbal preparations themselves. The main sources of information about medicinal plants / herbal products are pharmacists (39.7%) and people from the immediate area (28.4%), followed by the media (18.2%) and physicians (11.1%). Every fourth patient (24.5%) uses herbal products for the treatment of some health issues, while 69.5% of patients use herbal products to improve their health. 48.9% of them believe that herbal products are safe, but with some side effects, while 35.8% believe herbal products are completely free of any side effects. Half of respondents (51.4%) believe that herbal products are as effective as or more effective than synthetic medicines. Less than one-third of patients (29.8%) indicated that they knew the difference between herbal medicinal products and herbal dietary supplements. Still, a third of patients (36.7%) needed additional explanations for the use of herbal products. 76.6% of patients stated that they always receive advice from a pharmacist when purchasing herbal products.
Conclusion: The survey conducted in this work showed that elderly patients use herbal products to a considerable extent, which means that it is necessary to educate elderly patients on this matter. Pharmacists should play a vital role in this process and actively discuss the characteristics and proper use of herbal products with patients, especially having in mind the high possibility of interactions with conventional medicines and occurrence of side effects. Since the quality of some herbal products sometimes could be questionable, especially non-regulated ones, patients should be encouraged to purchase them from pharmacies and consult with pharmacists.

AB  - The study aimed to estimate and compare the prevalence and type of potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) between the STOPP/START original (v1) and updated version (v2) among older patients in various settings, as well as associated factors. The study included 440 patients attending a community pharmacy, 200 outpatients and 140 nursing home users. An increase in the prevalence of STOPP v2 (57.9%) compared to v1 (56.2%) was not statistically significant in the total sample and within each setting (p>0.05). A decrease in the prevalence of START v1 (55.8%) to v2 (41.2%) was statistically significant (p<0.001) in the total sample and within each setting (p<0.05). Drug indication (32.9%) and fall-risk medications (32.2%) were most commonly identified for STOPP v2, while cardiovascular system criteria (30.5%) were the most frequently detected for START v2. The number of medications was the strongest predictor for both STOPP v1 and v2, with odds ratio values of 1.35 and 1.34, respectively. Patients’ characteristics associated with the occurrence of STOPP and START criteria were identified. According to both STOPP/START versions, the results indicate a substantial rate of potentially inappropriate prescribing among elderly patients. The prevalence of PIMs was slightly higher with the updated version, while the prevalence of PPOs was significantly lower.

AB  - Today, there are a number of applications that allow you to monitor physical activity
and health parameters or schedule a medical examination, and can also help you recognize a
health problem and react in time (1, 2). The aim of the present study was to assess the usage
of health applications (HApps, health-related mobile and/or web applications) among
citizens in Serbia.
The anonymous online questionnaire was distributed via social media in the spring of
2020. Data were processed using the IBM SPSS. 506 respondents participated in the
research, of which 155 were from the health profession. The majority of respondents were
female (73.9%), and the average age was 36.88 ± 11.22. About half of the respondents
(48.2%) have a university degree, and 74.9% are employed. Installed HApps on
phone/computer have 18.2% of respondents, with a statistically significant difference (p
<0.01) between health professionals (25.8%) and non-health (14.8%). The most commonly
used HApps among health professionals are those related to their professional work
(14.7%), followed by general health (3.8%) and specific diseases (1.9%). Non-health
professional respondents mostly used applications related to general health (5.4%), fitness
(2.0%) and the chosen doctor (1.4%). Only 0.6% of citizens used COVID-19 pandemic
applications. The importance of HApps is still not sufficiently recognized in Serbia. Given the
potential in controlling chronic diseases and other health conditions, especially among a
population with limited access to health care and health information, they should be more
integrated into the health system.

stručni rad (14.7%), opšte zdravlje (3.8%) i specifične bolesti (1.9%). Ispitanici koji nisu iz
zdravstvene struke najviše su koristili aplikacije koje se odnose na opšte zdravlje (5.4%),
fitnes (2.0%) i izabranog lekara (1.4%). Aplikacije u vezi sa COVID-19 pandemijom koristilo
je svega 0.6% građana. Značaj HApps još uvek nije dovoljno prepoznat u Srbiji. S obzirom na
potencijal u kontroli hroničnih bolesti i drugih zdravstvenih stanja, naročito među
populacijom sa ograničenim pristupom zdravstvenoj zaštiti i zdravstvenim informacijama,
trebalo bi ih više integrisati u zdravstveni sistem.

AB  - The beneficial effects of probiotics have been demonstrated in wide range of pathological conditions. One of 
the major mechanisms of action is through the regulation of host immune response. Likewise, the probiotics 
that colonize the human host are most numerous in the intestines. The commensal intestinal microbiome 
contributes to increased resistance against infections, host immune system differentiation, and synthesis of 
nutrients. 
Probiotics such as Lactobacillus and Bifidobacterium can restore host-health by eliminating pathogens and 
regulating immune responses in intestinal epithelial cells. Also, circumstantial evidence has supported the 
presumption that probiotic supplementation decreases the severity of COVID-19 responses. Literature data 
show that the immunomodulating activity of vitamin D, which absorption could improve by probiotics, plays 
a role in viral infections. An analytical retrospective approach to the data of 34 pharmacies of Association 
Apoteka plus from all country region showed a significant increase in sales of probiotics (2019/20 by 29% 
and 2020/21 by 47%) and vitamin D (2020/21 registered drug 53.6 %, supplements 19.9%). In addition, sales 
of Over the counter (OTC) cold and flu medicines remained flat. In conclusion, self-care and prevention have 
been at a high position during the last three years, but still, due to serious health problems such as COVID 19, 
patients are seeking professional health services and prescription drugs.
