Objective: The aim of this study was to evaluate the cost-effectiveness of different glucosamine formulations and preparations used for the management of osteoarthritis in Thailand compared with placebo.

Methods: We used a validated model to simulate the individual patient Utility score from aggregated data available from 10 different clinical trials. We then used the Utility score to calculate the quality-adjusted life year (QALY) over 3 and 6 months treatment period. We used the public costs of glucosamine products available in Thailand in 2019 to calculate the incremental cost-effectiveness ratio. We separated the analyses for prescription-grade crystalline glucosamine sulfate (pCGS) and other formulations of glucosamine. A cost-effectiveness cut-off of 3.260 USD/QALY was considered.

Results: Irrespective of the glucosamine preparation (tablet or powder/capsule), the data show that pCGS is cost-effective compared with placebo over a 3 and 6 months. However, the other glucosamine formulations (e.g., glucosamine hydrochloride) never reached the breakeven point at any time.

Conclusions: Our data show that pCGS is cost-effective for the management of osteoarthritis in the Thai context while other glucosamine formulations are not.

Introduction: The aim of our study is to evaluate the nutritional status of patients in an acute geriatric unit.

Methods: Patients included in the study were hospitalized in an acute geriatric unit over a period of 6 months. The nutritional status of each patient was evaluated with anthropometric measurements (the BMI and MNA scales), and biological measurements (albumin). Frailty was evaluated using three scales: the Fried scale, the CFS and the modified SEGA scale.

Results: A total of 359 patients were included, comprising 251 women (70%) with an average age of 85.28 years. The study showed that 102 elderly subjects were considered undernourished according to the BMI scale, 52 subjects were undernourished according to the MNA scale, and 50 subjects were undernourished according to their albumin levels. The relationships between undernutrition and frailty syndrome studied in our work show that elderly subjects who are undernourished according to the BMI and MNA scales are significantly frail according to Fried and Rockwood, whereas those who are undernourished according to their albumin levels are significantly frail according to Fried and the modified SEGA scale.

Conclusion: The relationship between undernutrition and the frailty syndrome is close, and their joint screening is necessary, whether on an outpatient or in-hospital basis, in order to prevent negative events related to comorbidities and geriatric syndromes.

Background: Abiraterone acetate is a cytochrome P450 17A1 (CYP17A1) inhibitor that is indicated for use in both castration-resistant and castration-sensitive prostate cancer patients. To manage the mineralocorticoid effects of CYP17A1 inhibition, a glucocorticoid such as dexamethasone is co-administered with abiraterone. The goal of the present study was to understand the effect of dexamethasone on the disposition of abiraterone. Methods: Adult male CD-1 mice were treated with either dexamethasone (80 mg/kg/day) or vehicle for three consecutive days, followed by the administration of a single dose of abiraterone acetate (180 mg/kg) as an oral gavage. Blood samples were collected by tail bleeding at timepoints between 0 to 24 h. Subsequently, abiraterone was extracted from the mouse serum using a neutral pH condition and serum abiraterone levels were determined using a liquid chromatography-mass spectrometry assay. Results: Our results demonstrated that dexamethasone lowered the maximum plasma concentration and area under the curve parameters by approximately five- and ten-fold, respectively. Similar effects were also observed on the plasma half-life and oral clearance parameters. This is the first report of dexamethasone effect on abiraterone disposition in vivo. Conclusions: We conclude that dexamethasone has the potential to reduce the plasma abiraterone level and thus compromise its CYP17A1 inhibitory ability in the procancerous androgen biosynthesis pathway. Thus, use of a higher abiraterone dose may be warranted when used alongside dexamethasone.

A lack of reliable information hinders the clinician evaluation of suspected herb-drug interactions. This pilot study was a survey-based study conceived as a descriptive analysis of real-life experiences with herb-drug interaction from the perspective of herbalists, licensed health-care providers, and lay persons. Reported dietary supplement-drug interactions were evaluated against the resources most commonly cited for the evaluation of potential supplement-drug interactions. Disproportionality analyses were performed using tools available to most clinicians using data from the U.S. Federal Adverse Event Reporting System (FAERS) and the US Center for Food Safety and Applied Nutrition (CFSAN) Adverse Event Reporting System (CAERS). Secondary aims of the study included exploration of the reasons for respondent use of dietary supplements and qualitative analysis of respondent's perceptions of dietary supplement-drug interaction. While agreement among reported supplement-drug interactions with commonly cited resources for supplement-drug interaction evaluation and via disproportionality analyses through FAERS was low, agreement using data from CAERS was high.

Background: The intraovarian administration of autologous platelet-rich plasma (PRP) acts beneficially for the stimulation of follicle production in women presenting different forms of ovarian dysfunction. This pilot study aimed to evaluate and provide significant data regarding the efficacy of PRP to rejuvenate the ovaries. Methods: A total of 253 women aged 22-56 years, were divided into five groups, based on their status. All participants signed for informed consent for the current study. Blood sampling, preparation of PRP and intraovarian infusion of the latter were performed on all participants. The evaluation of PRP efficacy, a two-month follow-up detecting the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) and anti-mullerian hormone (AMH), was performed for all participants. For women with advanced ages (>48 years), the restoration and regularity of the menstrual cycle were additionally evaluated. Results: After the two-month follow-up, the majority of the participants presented improvement in their hormonal profiles. Additionally, 17% of the women in this pilot study successfully conceived. The restoration of the menstrual cycle was detected in 15% of the women with advanced ages. Conclusions: Intraovarian infusion of autologous PRP exhibited remarkable evidence and promising results to restore ovarian insufficiency.

Background: The intestinal ecosystem, including epithelium, immune cells, and microbiota, are influenced by diet and timing of food consumption. The purpose of this study was to evaluate various dietary protocols after ad libitum high fat diet (HFD) consumption on intestinal morphology and mucosal immunity.

Methods: C57BL/6 male mice were fed a 45% high fat diet (HFD) for 6 weeks and then randomized to the following protocols; (1) chow, (2) a purified high fiber diet known as the Daniel Fast (DF), HFD consumed (3) ad libitum or in a restricted manner; (4) caloric-restricted, (5) time-restricted (six hours of fasting in each 24 h), or (6) alternate-day fasting (24 h fasting every other day). Intestinal morphology and gut-associated immune parameters were investigated after 2 months on respective protocols.

Results: Consuming a HFD resulted in shortening of the intestine and reduction in villi and crypt size. Fasting, while consuming the HFD, did not restore these parameters to the extent seen with the chow and DF diet. Goblet cell number and regulatory T cells had improved recovery with high fiber diets, not seen with the HFD irrespective of fasting.

Conclusion: Nutritional content is a critical determinant of intestinal parameters associated with gut health.

Background: The regulation of microcirculation depends on the dynamic interaction of different factors: the autonomic nervous system plays a pivotal role in the blood flow and acupuncture can modulate it, obtaining different results depending on the site, the frequency, and the intensity of the stimulation. Methods: 18 healthy subjects have been enrolled and have undergone two sessions of electroacupuncture stimulations: one session using high frequency and one with low frequency. Microcirculation has been monitored continuously during stimulation using the laser Doppler method. Results: The microcirculatory parameters have shown a significant difference between high and low-frequency stimulation, suggesting that low-frequency stimulation is more effective for obtaining a vasodilator effect. Discussion: Our results show that low-frequency stimulation can increase the cutaneous microcirculatory flux, without significantly modifying blood pressure and heart rate. The auricular stimulation causes an increase in the activity of the vagus nerve, increasing the cholinergic activity without acting on post-junctional muscarinic receptors. Conclusion: Auricular acupuncture has a significant impact on the regulation of microcirculation.

Patients affected by global aphasia are no longer able to understand, produce, name objects, write and read. It occurs as a result of functional damage of ischemic or hemorrhagic origin affecting the entire peri-silvan region and frontal operculum. Rehabilitation training aims to promote an early intervention in the acute phase. We described a case of a 57-year-old female patient with left intraparenchymal fronto-temporo-parietal cerebral hemorrhage and right hemiplegia. After admission to clinical rehabilitative center, the patient was not able to perform simple orders and she presented a severe impairment of auditory and written comprehension. Eloquence was characterized by stereotypical emission of monosyllabic sounds and showed compromised praxis-constructive abilities. Rehabilitation included a program of Neurologic Music Therapy (NMT), specifically Symbolic Communication Training Through Music (SYCOM) and Musical Speech Stimulation (MUSTIM). Rehabilitative treatment was measured by improved cognitive and language performance of the patient from T0 to T1. Music rehabilitative interventions and continuous speech therapy improve visual attention and communicative intentionality. In order to confirm the effectiveness of data presented, further extensive studies of the sample would be necessary, to assess the real role of music therapy in post-stroke global aphasia.

In this article, we discuss the main aspects regarding the recognition of cell surface glycoconjugates and the immunomodulation of responses against the progression of certain pathologies, such as cancer and infectious diseases. In the first part, we talk about different aspects of glycoconjugates and delve deeper into the importance of N-glycans in cancer immunotherapy. Then, we describe two important lectin families that have been very well studied in the last 20 years. Examples include the sialic acid-binding immunoglobulin (Ig)-like lectins (siglecs), and galectins. Finally, we discuss a topic that needs to be better addressed in the field of glycoimmunology: the impact of oncofetal antigens on the cells of the immune system. New findings in this area are of great importance for advancement, especially in the field of oncology, since it is already known that cellular interactions mediated by carbohydrate-carbohydrate and/or carbohydrate proteins are able to modulate the progression of different types of cancer in events that compromise the functionality of the immune responses.
