RESUMEN
The clinical context of drug interactions detected by automated analysis systems is particularly important in older patients with multimorbidities. We aimed to provide unique, up-to-date data on the prevalence of potentially inappropriate medications (PIMs) and drug-drug interactions (DDIs) in the Polish geriatric population over 80 years old and determine the frequency and the most common PIMs involved in DDIs. We analyzed all non-prescription and prescription drugs in a representative national group of 178 home-dwelling adults over 80 years old with excessive polypharmacy (≥10 drugs). The FORTA List was used to assess PIMs, and the Lexicomp® Drug Interactions database was used for DDIs. DDIs were detected in 66.9% of the study group, whereas PIMs were detected in 94.4%. Verification of clinical indications for the use of substances involved in DDIs resulted in a reduction in the total number of DDIs by more than 1.5 times, as well as in a nearly 3-fold decrease in the number of interactions requiring therapy modification and drug combinations that should be strictly avoided. The most common PIMs involved in DDIs were painkillers, and drugs used in psychiatry and neurology. Special attention should be paid to DDIs with PIMs since they could increase their inappropriate character. The use of automated interaction analysis systems, while maintaining appropriate clinical criticism, can increase both chances for a good therapeutic effect and the safety of the elderly during treatment processes.
RESUMEN
BACKGROUND: Chronic heart failure (CHF) is a major healthcare problem. However, there are no epidemiological studies assessing the prevalence of CHF in the general population with diagnosis based on algorithms recommended for clinical practice. AIM: The aim of the HF-Pomorskie survey was to assess the prevalence of three basic components of the 2016 ESC diagnostic algorithm for CHF (symptoms, N-terminal pro B-type natriuretic peptide [NT-proBNP], and abnormalities on echocardiography) and to determine whether this algorithm may be applicable to studies in general population samples. METHODS: The study was performed in a representative sample of 313 adults (170 women and 143 men) aged between 20 and 90 years (mean 55.2 years [15.3]) in Northern Poland. A questionnaire to determine New York Heart Association [NYHA] class, laboratory tests including NT-proBNP, as well as transthoracic echocardiography and spirometry examinations were performed in all subjects. RESULTS: Dyspnea (NYHA class II-IV) was reported by 13.7% of recruited participants. Dyspnea and elevated levels of NT-proBNP (>125 pg/ml) were found in 7.7% of all examined subjects, while dyspnea, elevated NT-proBNP levels accompanied by systolic or diastolic abnormalities on echocardiography occurred in 4.8%. In the group without dyspnea (86.3% of all examined subjects), every sixth subject had an elevated level of NT-proBNP. On the other hand, 5.8% of studied subjects reported a previous diagnosis of CHF, which was confirmed using the current ESC algorithm in 78% of them. CONCLUSIONS: The prevalence of CHF assessed by the 2016 ESC diagnostic algorithm in the representative sample of adults was equal to 4.8%. The clinical algorithm for the diagnosis of CHF is fully applicable to the representative surveys in the general population. However, due to logistic and economic factors, echocardiography examination and NT-proBNP determination can be limited to patients reporting dyspnea or previous diagnosis of CHF.

The purpose of the investigation was to evaluate the effect of the selected bioflavonoids curcumin, resveratrol and baicalin on the wound healing process in an in vitro model. In the study, Balb3t3 and L929 cell lines were used. The first step was the evaluation of the cytotoxicity of the substances tested (MTT assay). Then, using the scratch test (ST), the influence of bioflavonoids on the healing process was evaluated in an in vitro model. The second stage of the work was a mathematical analysis of the results obtained. On the basis of experimental data, the parameters of the Brian and Cousens model were determined in order to determine the maximum value of the cellular and metabolic response that occurs for the examined range of concentrations of selected bioflavonoids. In the MTT assays, no cytotoxic effect of curcumin, resveratrol and baicalin was observed in selected concentrations, while in the ST tests for selected substances, a stimulatory effect was observed on the cell division rate regardless of the cell lines tested. The results obtained encourage further research on the use of substances of natural origin to support the wound healing process.
RESUMEN
BACKGROUND: The prevalence of frailty and its components may be affected by age, diseases and geriatric deficits. However, the current operational definition of frailty assigns equal weight to the five components of frailty. AIMS: To perform a population-based assessment of physical frailty, its prevalence, and distribution of its components across different age, disease and deficit spectrum. METHODS: From 2018 to 2019, we conducted a face-to-face cross-sectional assessment of a representative sample of older Poles. We obtained data on frailty components, chronic disease burden, and prevalence of particular diseases and geriatric deficits. We calculated weighted population estimates, representative of 8.5 million older Poles, of prevalence of frailty and its components across the disease burden, associated with the particular diseases and the geriatric deficits present. RESULTS: Of 10,635 screened persons ≥ 60 years, 5987 entered the face-to-face assessment. Data of 5410 have been used for the present analysis. Seventy-two percent of the population are burdened with at least one frailty component. The estimated weighted population prevalence (95% CI) of frailty was 15.9% (14.6-17.1%), and of pre-frailty 55.8% (53.3-58.2%). Slow gait speed predominated across disease burden, specific diseases, geriatric deficits and the age spectrum. Overall, the prevalence of slow gait speed was 56.3% (52.7-60.0%), followed by weakness 26.9% (25.4-28.4%), exhaustion 19.2% (17.6-20.8%), low physical activity 16.5% (14.8-18.3%), and weight loss 9.4% (8.4-10.3%). CONCLUSIONS: Slow gait speed predominates among the components of frailty in older Poles. This may affect the component-tailored preventive and therapeutic actions to tackle frailty.

BACKGROUND: Due to advanced age, multimorbidity and polypharmacotherapy, older patients are predisposed to drug interactions and the adverse effects of inappropriate drug combinations. OBJECTIVES: To provide up-to-date data on predisposing factors and the prevalence of possible drug interactions in the Polish geriatric population and to promote automated analysis programs as part of safe pharmacotherapy. MATERIAL AND METHODS: We used the Lexicomp® Drug Interactions database to assess pharmacological interactions between active substances included in all types of preparations (prescription drugs, over-the-counter drugs, vitamins, nutritional preparations, and dietary supplements) used at least once in the 2 weeks preceding the study, among 2633 home-dwelling people aged >65 years. The variables measured included age, sex, place of residence, level of education, and multimorbidity. Post-stratification was used to weigh the sample structure against the Polish population in 2017. RESULTS: Drug interactions were identified in 81.2% of all individuals. The mean number (with 95% confidence interval (95% CI)) of all drug interactions was 4.24 (4.02-4.46), and the median value (with 1st and 3rd quartiles (Q1-Q3)) was 3 (1-6). At least 1 category C interaction was observed in 75.8% of all study participants, 24.3% had 1 or more category D interaction, and 4.3% had 1 or more category X interaction. The most important predisposing factor to drug interactions was multimorbidity. CONCLUSIONS: This study identified a high prevalence of potential drug interactions in the Polish geriatric population. Automated analysis systems deliver useful information on pharmacological interactions and should be promoted in the Polish healthcare community as tools to support pharmacotherapy.

Obesity is associated with an increased risk of morbidity and mortality; however, data suggest that in old age, obesity is not detrimental. The study's objective was to verify whether obesity frequency still increases in Polish Caucasian seniors and to verify the "obesity paradox". Five thousand and fifty-seven community-dwelling individuals aged ≥ 65 years completed a detailed medical questionnaire, underwent measurements of the body mass index (BMI) and the waist circumference (WC), and an evaluation of physical and cognitive performances. Over a decade, general obesity increased by 2.1%, mostly due to a 3.9% increase in men. Abdominal obesity increased by 1.0%, mainly due to males, in whom it increased by 3.9%. Obesity increased the risk of several aging-related diseases, but this effect was less pronounced in the oldest-old. Obesity did not adversely affect the physical and cognitive functioning or mortality. Through a multivariable analysis, the BMI and WC remained the independent predictors of the Katz Activities of Daily Living score (p < 0.001 and p < 0.05, respectively) and Mini-Mental State Examination score (both p < 0.001). The Kaplan−Meier survival curves revealed that overweight and obesity classes 1 and 2 were associated with the lowest mortality. Through a multivariable analysis, overweight, class 1 obesity, and abdominal obesity remained the independent predictors of a decreased mortality (all p < 0.001). In conclusion, we found that overweight and obesity are not detrimental in seniors, including the oldest-old. We suggest that the anthropometric values defining obesity should be modified for age-advanced people.

INTRODUCTION: The world's elderly population is growing dramatically. Pharmacotherapy in seniors is particularly challenging due to changes in metabolism, multimorbidity, and a great interest in nonprescription drugs. OBJECTIVES: We aimed to provide uptodatedata on pharmacotherapy in the geriatric population of Poland, to determine factors predisposing to polypharmacy and excessive polypharmacy, and to identify seniors who are most likely to require multidisciplinary interventions in the field of pharmacotherapy. PATIENTS AND METHODS: We analyzed the use of all prescription and nonprescription drugs taken within 2 weeks preceding the study in a representative national sample of 3014 homedwelling seniors aged over 65 years. The variables of age, sex, place of residence, level of education, and multimorbidity were considered. Poststratification was used to balance the sample structure to match the Polish population of 2017. RESULTS: Consumption of at least 1 drug was reported by 90.7% of the participants, and the mean number of drugs used was 5.01 (95% CI, 4.87-5.15). At least 1 nonprescription drug was used by 44.2% of the respondents, with a mean number of 0.52 (95% CI, 0.49-0.55). More than 5 drugs were taken by 53.5% of the entire population, while the use of more than 10 drugs was reported by 8.7% of the respondents, with multimorbidity as the most predisposing factor. Singlepill combinations accounted for 27.2% of medications. CONCLUSIONS: The high prevalence of polypharmacy resulting from multimorbidity confirms the need for the implementation of combined medical and pharmaceutical care of the geriatric patients.

The brewing sector is a significant part of the global food industry. Breweries produce large quantities of wastes, including wastewater and brewer's spent grains. Currently, upcycling of food industry by-products is one of the principles of the circular economy. The aim of this review is to present possible ways to utilize common solid by-product from the brewing sector. Brewer's spent grains (BSG) is a good material for sorption and processing into activated carbon. Another way to utilize spent grains is to use them as a fuel in raw form, after hydrothermal carbonization or as a feedstock for anaerobic digestion. The mentioned by-products may also be utilized in animal and human nutrition. Moreover, BSG is a waste rich in various substances that may be extracted for further utilization. It is likely that, in upcoming years, brewer's spent grains will not be considered as a by-product, but as a desirable raw material for various branches of industry.
