Unexpected isolation, which has not yet been seen on a global scale, has created the conditions for evaluating nutrition in a situation of reduced spatial activity. The study aimed to assess the influence of lockdown on selected eating habits of Polish adults. An anonymous questionnaire was conducted, including questions about eating habits and self-reported anthropometric measurements, referring to “before” and “during” lockdown. We reported the findings of 312 adults (aged 41.12 ± 13.05 years). Overall, 64.1% of the participants were women, 77.7% urban inhabitants and 78.6% employed. The average length of social isolation was 50.79 ± 10.53 days. The majority (51.6%) of the respondents did not eat outside the house during lockdown (p < 0.0001). The number of meals eaten during the day during lockdown increased significantly, 11.2% of the respondents ate 5 and more meals (p < 0.0001). The percentage of people snacking between meals increased by 5.1% during lockdown (p = 0.0001). Eggs, potatoes, sweets, canned meat and alcohol were consumed considerably more commonly during lockdown, while fast-food products, instant soups and energy drinks were eaten or drunk significantly less frequently. A marked decrease in the number of daily servings of the following products was observed: bakery products, red meat, fast food, instant soups, sweet beverages and energy drinks. Conversely, the number of daily servings of sweets and canned meat significantly increased. Two thirds of the respondents reported body weight changes, with 45.86% of the participants being overweight during lockdown. Significant changes in the diet of Polish adults were found during lockdown due to COVID-19.

Introduction Clinical studies have revealed that fixed-dose combinations (FDCs) of drugs can have a better effect on blood pressure than free-equivalent combinations (FECs). Our objectives were to perform an up-to-date assessment of the effectiveness of FDCs and FECs in antihypertensive...

Objectives: The aim of this study was to review the requirements for the reimbursement of biosimilars and to compare the reimbursement status, market share, and reimbursement costs of biosimilars in selected Central and Eastern European (CEE) countries. Methods: A questionnaire-based survey was conducted between November 2016 and January 2017 among experts from the following CEE countries: Bulgaria, Czech Republic (Czechia), Croatia, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia, and Romania. The requirements for the pricing and reimbursement of biosimilars were reviewed for each country. Data on the extent of reimbursement of biologic drugs (separately for original products and biosimilars) in the years 2014 and 2015 were also collected for each country, along with data on the total pharmaceutical and total public health care budgets. Results: Our survey revealed that no specific criteria were applied for the pricing and reimbursement of biosimilars in the selected CEE countries; the price of biosimilars was usually reduced compared with original drugs and specific price discounts were common. Substitution and interchangeability were generally allowed, although in most countries they were at the discretion of the physician after a clinical assessment. Original biologic drugs and the corresponding biosimilars were usually in the same homogeneous group, and internal reference pricing was usually employed. The reimbursement status of biosimilars in the majority of the countries was the same and amounted to 100%. Generally, the higher shares of expenditures were shown for the reimbursement of original drugs than for biosimilars, except for filgrastim, somatropin and epoetin (alfa and zeta). The shares of expenditures on the reimbursement of biosimilar products ranged from 8.0% in Estonia in 2014 to 38.1% in Lithuania in 2015, and generally increased in 2015. The share of expenditures on reimbursement of biosimilars in the total pharmaceutical budget differed between the countries, with the highest observed for Hungary and the lowest – for Croatia. Conclusions: The requirements for the pricing and reimbursement of biosimilar products as well as the access of patients to biologic treatment do not differ significantly between the considered CEE countries. Biosimilar drugs significantly influence the reimbursement systems of these countries.

The aim of the present study was to conduct a meta-analysis of the effectiveness of tofacitinib, a novel oral Janus kinase inhibitor, recently approved for the treatment of active rheumatoid arthritis in patients who have failed previous treatment with methotrexate (MTX) or other disease-modifying antirheumatic drugs (DMARDs). A systematic literature search was conducted in PubMed, EMBASE, Cochrane Library, and other databases till 3 May 2013. All included studies were analyzed with the use of the Review Manager 5.1.0. software according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement protocol. Nine randomized controlled trials (RCTs) comparing tofacitinib with placebo were identified. Two of them additionally provided the comparison with adalimumab. However, only eight RCTs met the inclusion criteria for the meta-analysis. The overall results of the meta-analysis showed that tofacitinib provided a statistically significant improvement according to the response criteria (ACR20/50/70) after 12 weeks of treatment when compared to placebo (p < 0.00001). Moreover, it was demonstrated that tofacitinib was significantly superior to adalimumab in achieving the ACR50 response criteria at week 12 (p = 0.003). For the safety analysis, there were no statistically significant differences between tofacitinib-, adalimumab-, and placebo-treated patients in respect to the risk of serious adverse events or treatment discontinuation due to adverse reactions (p > 0.05). The findings of this systematic review with meta-analysis indicate that tofacitinib monotherapy or with background methotrexate provides early statistically significant and clinically important improvement in rheumatoid arthritis symptoms and has an acceptable safety profile comparable to that of placebo. The results of the present meta-analysis show that the frequency of serious adverse events was not increased after tofacitinib treatment. In addition, tofacitinib might provide an effective treatment option compared to intravenous or subcutaneous biological DMARDs, as suggested by the result of the comparison made regarding tofacitinib vs. adalimumab ACR50 response rate.
