Worldwide, hundreds of millions of people have been infected with COVID-19 since December 2019; however, about 20% or less developed severe symptoms. The main aim of the current study was to  assess  the  relationship  between  the  severity of Covid-19 and different clinical and laboratory parameters. A total number of 466 Arabs have willingly joined this prospective cohort. Out of the total number, 297 subjects (63.7%) had negative COVID-19 tests, and thus, they were recruited as controls, while 169 subjects (36.3%) who tested positive for COVID-19 were enrolled as cases. Out of the total number of COVID-19 patients, 127 (75.15%) presented with mild symptoms, and 42 (24.85%) had severe symptoms. The age range for the participants was 20 to 82 years. Compared with controls, the severity of the disease was associated with significantly high ferritin levels (P < 0.001). The severity of the disease was also associated with a significant increase in C-reactive protein (P < 0.001), D-dimer (P < 0.001), white blood cell count (WBC) (P < 0.01), IgM (P < 0.001), and Granulocytes (P < 0.01). In addition, severe COVID-19 symptoms in the current study were associated with a significant decrease in lymphocytes (P < 0.01). There was a four-fold increase in serum ferritin levels in COVID-19 patients presented with severe symptoms upon admission. The former was associated with significantly high levels of CRP and D-dimer. Thus, hyperferritinemia, together with high CRP and D-dimer concentrations, may serve as reliable predictors for disease severity and poor prognosis in Arabs with COVID-19.

The paper highlights the correlations between the results of instrumental colour measurement and the content of certain metals in kinds of honey. Sufficiently close correlations may lead to the development of procedures for the rapid determination of the content of these metals in honey by colour measurement without the need for more demanding sample preparation.

Fridrich Jakub Fuker (1749-1805), a physician from Košice, is the author of works on medical topics, as well as works on social life. In addition to his medical practice, he also owned a pharmacy, and his short work on a universal preventive tincture is related to this. The author argues that there is no universal medicine, but it is possible to prepare a universal preventive preparation suitable for everyone, every age and sex. Fuker has announced that he will prepare such a tincture, available in his pharmacy, along with information on its use. However, he did not divulge its composition, as supposedly, any physician knowledgeable in the matter would figure it out on his own. With the universal tincture, Fuker abandoned rational medicine, perhaps suffering from involutional depression or acting as a salesman.

The aim of the study was to point out the contribution of new invasive therapeutic procedures in the treatment of advanced stages of Parkinson's disease (PD) in comparison with classical oral pharmacotherapy. Data originated from a group of 43 patients with PD, 39% (17) with classic treatment, 23% (10) with intestinal gel of methyl ester levodopa (Duodopa), 19% (8) of patients were using subcutaneous delivery of apomorphine (APO) and the same quantity of patients had undergone deep brain stimulation (DBS). Majority of patients had advanced stages of PD, stage 4, by standards of Hoehn and Yahr scale (Hoehn and Yahr, 1967). Research observed improvement in majority of patients with novel treatments. A positive effect was also noted in the reduced need for oral therapy, where there was a significant decrease in all new therapies. Benefits were observed in the amount of antiparkinsonic drugs taken per os, where we observed reduction in all new therapies. A positive effect of the new therapeutic approaches in reducing "off" periods in patients has also been noted. In the case of Duodopa and DBS, the "off" period was shortened up to 50% and in the apomorphine pump up to 40%. Patients also reported reduction of some symptoms like rigidity, tremor and bradykinesis while dyskinesis still remains suba challenge. On the basis of the obtained results, it can be concluded that new therapeutic procedures for PCh will make it possible to manage symptoms typical of advanced stages of the disease, which without these procedures would lead to disability, which is the main reason for their indication. However, in early stages, well responding patients or in slow progressing disease oral antiparkinsonics are remaining as golden standard of treatment. This is not just due to good response but also because these classic drug formulations are significantly less expensive. In Slovakia, novel treatments are accessible through healthcare insurance only after secondary revision by insurance company doctors.

The main goal of this article is to present the results of the synthesis of new alkyl derivatives of 5-(2-bromo4-fluorophenyl)-4-ethyl-4H-1,2,4-triazole-3-thiol and molecular docking studies against COX-1 and COX-2. Previous studies have established a wide range of biological activity of 1,2,4-triazole derivatives. Therefore, it was essential to determine how a new series of 1,2,4-triazole derivatives would provide potential anti-inflammatory activity. To reach the goal, raw alkyl derivatives of 5-(2-bromo-4-fluorophenyl)-4-ethyl-4H-1,2,4-triazole-3-thiols (2a-2i) from 5-(2-bromo-4-fluorophenyl)-4-ethyl-4H-1,2,4-triazole3-thiol (1e) were obtained. The structure of the synthesized compounds was confirmed by 1H-NMR elemental analyses. The individuality and purity of compounds were confirmed by the method of liquid chromatography-mass spectrometry. These compounds have a relatively simple synthesis scheme, which gives them an advantage in creating a potential drug, and the appearance of alkyl radicals in the molecule should positively affect pharmacokinetic indicators, stability, selectivity, and bioavailability. An in silico study was conducted for the synthesized compounds, namely molecular docking, in relation to the interaction with COX-1 and COX-2. Based on the selectivity indexes of binding modes observed for the selected compounds (2e, 2g) with active COX-1 centers, it was found that compounds can reliably exhibit their anti-inflammatory effect through the prostaglandin biosynthesis pathway, inhibiting COX-1 instead of COX-2. The effect of hydrophobic interactions of alkyl groups of 1,2,4-triazole derivatives on changes in affinity and selectivity to COX-1 or COX-2 has also been proven. Therefore, derivatives of 1,2,4 are promising candidates for improvement, further study, and future development of new, more powerful antiinflammatory drugs for therapeutic use.

This study provides new empirical evidence on the changes in competition and entry decisions of pharmacies after regulatory changes. It investigates the development of the retail pharmacy market in Portugal, which underwent major regulatory changes in 2004 and 2007. Sale of OTC drugs and ownership of pharmacies were liberalized while entry restrictions related to market size and the location of new pharmacies prevailed. Our empirical strategy was based on entry models and provided indirect information on the toughness of competition and entry decisions of firms in the market. We estimated and compared the entry thresholds and their ratios before and after liberalization. Such a comparison allows to see if competition got tenser with OTC drugs deregulated. There were three main findings from the study. First, the entry thresholds decreased regardless of the number of pharmacies in the market, suggesting that room for the realization of profits is broader than it was in the past. Second, although the entry thresholds were lower in value, their increase was steeper with each incumbent in 2020, suggesting harsher price competition with new entrants. Third, the current rule of 3,500 patients per pharmacy is likely overly restrictive, pharmacies could break-even even in smaller markets.

This article presents the study results of the hypoglycemic properties among 1,2,4-triazole derivatives synthesized at the Department of Physical and Colloidal Chemistry of the Zaporizhzhia State Medical University. Today, many people have a sedentary way of life, also most of their diet contains products that they frequently use, which increase the level of glucose in the blood, which can provoke the development of serious diseases. Therefore, to date, the creation of drugs that exhibit hypoglycemic activity and have a low level of toxicity remains an urgent task for medicine and pharmacy. In the first stage of our research, acute toxicity prediction was performed. The hypoglycemic activity of the synthesized compounds was assessed by performing an intraperitoneal glucose tolerance test (IPGTT) with a change in the blood glucose concentration of the animal after its single intraperitoneal administration in the form of a 40% solution at a dose of 2 g/kg of rat body weight. Thirty-eight compounds of the different classes were studied for hypoglycemic activity. Zinc (II) 2-{5-[(3,4-methoxyphenyl)-3H-1,2,4-triazole-3-yl]thio} acetate (3.18) showed the highest efficiency in terms of the ability to lower blood glucose levels, namely, by 27.3% (approximately 1.3 times).

Based on the data in the Ph. Eur., some other newer pharmacopoeias and published experimental papers propose to revise the text of Ph. Eur. 2.5.8. First, it is necessary to specify which of the electrometric methods should be used to indicate the endpoint of diazotization titrations in Ph. Eur. (preferable potentiometry with a platinum indicating electrode). The amount of potassium bromide in the titration solution may be reduced to 1 g, the cooling of the solution before titration may be omitted from the framework procedure, and it may be specified in individual monographs if necessary to obtain accurate and correct results for some medicines. Diazotization titration can be performed in Ph. Eur. and can also be used to determine the content of some other medicines.

The most promising direction in the treatment of chronic prostatitis is the use of medicinal plants and preparations based on them, which contain natural compounds with a broad spectrum of pharmacological activity: anti-inflammatory, antimicrobial, reparative, immunomodulatory, hormone-regulating, antisclerotic, etc., and which can provide a complex therapeutic effect on the course of chronic prostatitis. A promising raw material in this direction is Tribulus terrestris L., a herbal preparation traditionally used to treat erectile dysfunction and atherosclerosis. This experimental work aims to study the anti-inflammatory activity of a thick extract of the Tribulus terrestris grass (freed from fruits) on the models of carrageenan and zymosan inflammation in rats. In the models of carrageenan and zymosan edema in rats, a thick extract of Tribulus terrestris L. in doses from 50 mg/kg to 200 mg/kg shows anti-inflammatory activity, the efficacy of which in the dose range of 150-200 mg/g in the initial stages of carrageenan inflammation is not inferior to sodium diclofenac at a dose of 8.0 mg/kg, and in the initial stages of zymosan inflammation, respectively, before the reference drug corvitin at a dose of 10 mg/kg. It indicates the anticyclogenase and antilipoxygenase properties of this thick extract.
