Emotional disorders associated to multiple sclerosis and psychological interventions: a literature review

DOI: 10.2478/amma-2021-0042

Multiple sclerosis is an unpredictable neurologic disease affecting 2.8 million people worldwide. Individuals with MS experience multiple physical and psychological symptoms such as depression, anxiety, fatigue, and pain that impact their general functioning and quality of life. The aim of this review is to highlight the importance of psychological interventions in reducing depression and anxiety symptoms associated with the diagnosis of multiple sclerosis. Cognitive and behavioral techniques are also useful in relieving the specific symptoms of multiple sclerosis. However, few studies have captured the psychological processes involved in reducing the symptoms of depression and anxiety, which is why greater concern is recommended in future studies in order to develop better psychological interventions tailored for patients with multiple sclerosis.

The antibacterial potential of biosynthesized silver nanoparticles using beech bark and spruce bark extracts

DOI: 10.2478/amma-2021-0043

Introduction: Lately, nanotechnology focuses on the green synthesis of AgNPs, using different plant materials, as this method is accessible, cost-efficient, and ecological. The study aimed to investigate the antibacterial potential of AgNPs synthesized using beech/spruce bark extracts (BBE/SBE) and silver salts (acetate/nitrate).
Method: The growth rates of Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 were evaluated in the presence of the AgNPs solutions. The checkerboard method was performed to evaluate if these solutions exert synergistic activity with gentamicin.
Results: For E. coli, synergistic effects were observed for the combination of gentamicin 0.25mg/L with AgNP BBE Nit (0.145mg/mL) and with AgNP SBE Ac (0,09mg/mL). For S. aureus, no synergistic effects were observed. Overall, the AgNP BBEs solutions combined with gentamicin presented lowest values of fractional inhibitory concentration than the ones registered for the combination of AgNP SBEs with gentamicin, for both bacterial strains. The growth rate of S. aureus was inhibited by all the tested AgNPs at the measured time points. For E. coli, after 24 hours of incubation, the growth rate was inhibited only in the presence of AgNP SBE Ac. After 6 hours of incubation, the growth rate of E. coli was almost stationary in the presence of AgNP BBE Nit.
Conclusions: The biosynthesis of AgNPs is a valuable choice for obtaining substances with antibacterial potential.

Apathy as Non-Motor Manifestation in Amyotrophic Lateral Sclerosis

DOI: 10.2478/amma-2021-0041

Although the term of amyotrophic lateral sclerosis (ALS) is often used interchangeably with motor neuron disease, ALS is universally accepted as a multisystem disorder. Cognitive impairment is an acknowledged feature of ALS, affecting language, memory and behaviour, and apathy is considered to be the prevalent behavioural alteration in ALS. It can be divided in three subtypes: executive, emotional and initiation apathy. Out of the three subtypes, initiation apathy is common among patients with ALS. Even in patients that do not meet the criteria for ALS with frontotemporal dementia, low-key neuropsychiatric and cognitive changes can be observed. Apathy has also been found to be systematically associated with disruptions in medial frontal cortex and subcortical structures in several neuroimaging studies that confirm the pre-existing brain lesions in the early stages of this disease. Thus, there is a growing body of evidence that motor signs and symptoms are accompanied or even preceded by cognitive and behavioural alterations, and screening for non-motor signs and symptoms can be clinically relevant.

Prosthodontic Management of Dentate Maxillectomy Patient: A Clinical Case Report

DOI: 10.2478/amma-2021-0038

Patients with minor defects of the alveolar ridge and hard palate can easily be treated by surgical closure, while patients with larger defects are more amenable to prosthetic restoration. The case report describes the rehabilitation of a dentate maxillectomy patient with a definitive closed hollow bulb cast partial obturator. A tripod retainer design was chosen for direct retention in the case. The tripod design consisted of a T-bar clasp placed on the left first central incisor and two embrasure clasps with buccal retention and palatal bracing components between the right first & second premolar and right first & second molar. A complete palate major connector was designed to ensure uniform distribution of functional load across tissues. The remaining teeth, the palate, and the rest provided support for the prosthesis. Prosthetic rehabilitation of the defect with a definitive obturator thus seals tissue openings in the palate, improves deglutition, speech, mastication, aesthetics, and significantly improves quality of life.

Soy polysaccharides therapeutic and technological aspects

DOI: 10.2478/amma-2021-0040

Soy polysaccharides represent a multipurpose class of chemicals that include both therapeutical and technological properties. Since they have been first time introduced in the pharmaceutical field, Soy polysaccharides were used in two different pharmaceutical formulations; sublingual tablets and in colon drug delivery. For the sublingual tablets, Soy polysaccharides under the brand name of Emcosoy© – were used as a superdisintegrant in concentrations between 4-8% showing comparable results with the artificial superdisintegrants (sodium starch glycolate, sodium croscarmellose, and polyvinylpyrrolidone). The second technological field where Soy polysaccharides were used is represented by colon drug delivery where it was used in combination with ethylcellulose showing a prolonged lag time compared to the results found in the literature. The medicinal effect of these polysaccharides consists of treating diarrhea. As it will be presented in the article, these chemical compounds tend to decrease the aqueous stool time in patients with diarrhea and to conduct to a softer stool in healthy patients. In conclusion, these polysaccharides present multiple purposes possessing a medicinal effect and also the possibility of being used as a double-faceted pharmaceutical excipient.

The Gestational Diabetes Mellitus Approach in Clinical Practice – A Narrative Review

DOI: 10.2478/amma-2021-0037

Gestational diabetes mellitus (GDM) is an increasingly condition in medical practice. In the absence of an effective therapeutic management, it can lead to significant maternal and neonatal complications with adverse health effects. Reducing the risk of morbidity is the goal achived by screening of all pregnant women and active involvement of health care staff and early medical intervention in case of detection of GDM. The aim of this review is to present the nowadays strategy of GDM approach. The management challenge is to maintain blood glucose levels within the targets recommended by current guidelines, which are in relatively narrow ranges. Nutritional intervention and lifestyle changes are of primary importance. If necessary insulin therapy is initiated, insulin analogues are preferable due to lower risk of hypoglycemia. Oral antidiabetics are not recommended in pregnancy, even if they are used in certain circumstances.

Mediation of Candida species growth and virulence by the proinflammatory cytokine IL-6

DOI: 10.2478/amma-2021-0036

Interleukin-6 (IL-6) is a cytokine with pleiotropic effects that might also influence the virulence traits of some microorganisms, but its direct influence over Candida spp. is currently unknown. The objective of the study is to determine the influence of IL-6 (250 pg/ml) on the growth rate and biofilm formation of C. albicans, C. parapsilosis, C. krusei, C. auris, and C. guilliermondii, as well as to analyze the influence of this citokine on the expression of three virulence genes (ALS3, HSP70, SAP2), respectively on the germ tube formation ability of C. albicans. The influence of IL-6 on growth rate was assessed by incubating the fungal cells in presence of IL-6 for 48 hours and assessing the optical density of the samples at five timepoints. The biofilm production in presence of IL-6 was studied in microtiter plates, using crystal-violet assay, the intensity of biofilms being evaluated by spectrophotometry. The expression of ALS3, HSP70, and SAP2 in C. albicans was studied by RT-PCR, reported to ACT1 housekeeping gene. The germ-tube test was performed to assess the influence of IL-6 on the filamentation rate of C. albicans. All test results were normalized against control, without added IL-6. The results showed that IL-6 influences the growth rate of C. albicans, C. parapsilosis, C. krusei, C. auris, and C. guilliermondii in a time-dependent way. Also, IL-6 inhibited the formation of biofilms for C. albicans and C. guilliermondii. In C. albicans cells, IL-6 induced upregulation of ALS3 and HSP70, while it down-regulated the SAP2 gene. IL-6 did not influence the germ-tube formation in C. albicans. In conclusion, IL-6 might exert, in vitro, direct effects on the virulence traits of Candida spp., and its influence is dependent on the exposure time. Non-albicans Candida species presented particular responses to IL-6.

Online pharmacy: customer profiling

DOI: 10.2478/amma-2021-0031

Introduction: Nearly three out of four European citizens purchase goods online. The main advantages of using an online pharmacy are lower prices and convenience. In addition, patients appreciate a higher degree of privacy and access to a wider selection of health products. Study shows that the number of online users is on the rise in major countries like the USA, EU member states or India.
Methods: The study is based on data collected in April 2020 at the country level (Romania) from a sample of 789 adults over the age of 18, using CATI. A simple random sampling procedure was applied, with a confidence interval of 3.5% and a confidence level of 95%.
Results: About 17.7% of Romanians have purchased healthcare products through online pharmacies or drugstores, of those 60% are women, between 30 – 64 years old (84 %), have a monthly income of more than 2700 lei (90%), and a university degree (76%). The most common reasons for choosing an online pharmacy are the ability to compare prices, shop quickly, and have prompt access to items and information, together with a wider range of products.
Conclusions: Respondents’ motivation to use online pharmacies appears to be more related to the benefits of the online media, rather than to some unmet needs in brick-and-mortar pharmacies. Search capabilities, access to more information, price comparison, as well as a larger range of products and availability 24/7 are some reasons why patients utilise online pharmacies to purchase medicines.
