Background: Recent studies suggested that individuals with metabolic disorders have altered function of adipocytes and adipose stem cell subpopulations, which impairs tissue homeostasis, promoting insulin resistance and diabetes development. The non-psychoactive phytocannabinoid CBD was found to modulate adipose tissue metabolism, however, its exact role in controlling ASCs’ fate is still poorly understood. Objectives: This investigation aimed to elucidate whether pretreatment of ASCs with CBD can protect against ER stress development and maintain the cytophysiological properties of cells. Methods: Human ASCs were cultured under control and adipogenic conditions. Prior to the experiments, cells in the experimental group were pretreated with CBD following the addition of an ER stress inducer—tunicamycin. After the experiments, the cells were subsequently tested for expression of the apoptotic, ER stress, and anti-inflammatory-related genes using RT-qPCR. Oxidative stress was analysed with flow cytometric assays. Results: Cells pretreated with CBD displayed decreased apoptosis and enhanced proliferation rate. Additionally, the expression of pro-inflammatory cytokines and miRNAs was significantly reduced. The obtained results also demonstrated an obvious reduction in intracellular accumulated ROS and NO, as well as mitigated ER stress through the down-regulation of IRE-1, PERK, CHOP, and ATF6 transcripts upon CBD treatment. Conclusion: The presented data provide the evidence that CBD protects ASCs against ER stress development and its complications and, thus, offers new insights for the management of obesity through the regulation of adipose tissue dynamics.

Introduction. Pharmacists play an important role in healthcare. Their functions are evolving and, in many countries, they actively participate in interdisciplinary patient treatment. One of the most common services provided by pharmacists as part of pharmaceutical care in community pharmacies involves medication reviews. Objective. The objective of this study was to evaluate the readiness of pharmacists to conduct medication reviews in community pharmacies. Materials and methods. This study comprises 493 pharmacists from community pharmacies in Poland. A questionnaire (developed for the purposes of this study) was used. It consisted of eight questions regarding readiness to conduct medication reviews, along with personal data. Results. A total of 63.9% of the pharmacists were ready to conduct medication reviews, and 23.1% already had experience in this area. Participants were of the opinion that this service should be funded by the Ministry of Health or a third-party public payer, and overall was valued by the participants at PLN 169.04 (SD = 280.77) net per patient. Conclusions. Pharmacists in Poland have expressed their readiness to conduct medical reviews. Implementation of this service in community pharmacies in Poland can have a significant impact on optimising patient health outcomes.

Cancer is associated with discomfort and many changes in patients’ lives to which they must adapt. The main objective of the study was to assess the use of the mini-MAC questionnaire scale among persons diagnosed with malignant cancer and to develop standards allowing differentiation of patients with diagnosed cancer in terms of their style of adjustment to the disease. The mini-MAC questionnaire is a widely used tool in assessing coping strategies among cancer patients. Sten standards have been developed to determine the level of results on the questionnaire scales in the low–average–high categories. The study included 1187 patients diagnosed with malignant cancer who are covered by outpatient care at the Maria Sklodowska-Curie Institute—Oncology Center in Warsaw. The questionnaire concerning mental adjustment to cancer was used (mini-MAC). Patients with cancer most often adopt strategies of fighting spirit and positive reevaluation. The variables that differentiate the results most significantly include gender, presence of metastasis, and the state of undergoing chemotherapy. The mini-MAC questionnaire should be a tool for psycho-oncological diagnosis of patients’ attitudes towards cancer. The obtained results indicate that cancer patients are characterized by their constructive style of adjustment to the disease.

The endoplasmic reticulum (ER) fulfills essential duties in cell physiology, and impairment of this organelle’s functions is associated with a wide number of metabolic diseases. When ER stress is generated in the adipose tissue, it is observed that the metabolism and energy homeostasis of the adipocytes are altered, leading to obesity-associated metabolic disorders such as type 2 diabetes (T2D). In the present work, we aimed to evaluate the protective effects of Δ9-tetrahydrocannabivarin (THCV, a cannabinoid compound isolated from Cannabis sativa L.) against ER stress in adipose-derived mesenchymal stem cells. Our results show that pre-treatment with THCV prevents the subcellular alteration of cell components such as nuclei, F-actin, or mitochondria distribution, and restores cell migration, cell proliferation and colony-forming capacity upon ER stress. In addition, THCV partially reverts the effects that ER stress induces regarding the activation of apoptosis and the altered anti- and pro-inflammatory cytokine profile. This indicates the protective characteristics of this cannabinoid compound in the adipose tissue. Most importantly, our data demonstrate that THCV decreases the expression of genes involved in the unfolded protein response (UPR) pathway, which were upregulated upon induction of ER stress. Altogether, our study shows that the cannabinoid THCV is a promising compound that counters the harmful effects triggered by ER stress in the adipose tissue. This work paves the way for the development of new therapeutic means based on THCV and its regenerative properties to create a favorable environment for the development of healthy mature adipocyte tissue and to reduce the incidence and clinical outcome of metabolic diseases such as diabetes.

(1) Introduction: Pharmacists are medical professionals who play an active role in the protection of public health. Since 2021, pharmacists with an appropriate certification have been authorised to administer vaccines against COVID-19. (2) Objective: The objective of this study was to ascertain the perceptions of patients about receiving vaccinations through community pharmacies. (3) Material and methods: This study was conducted in 2021. The research tool was an anonymous questionnaire published on the websites of patient organisations. Ultimately, 1062 patients participated in this study. (4) Results: This study shows that most of the respondents find community pharmacies more accessible than outpatient clinics (85.3%). Sixty-one percent of the respondents stated that getting vaccinated at pharmacies would be less time consuming than at outpatient clinics. Nearly every third respondent (29.5%) declared that they would get vaccinated if they received such a recommendation from a pharmacist. Fifty-six percent of the respondents were of the opinion that the administration of vaccines by pharmacists would relieve the burden on medical staff and the healthcare system. (5) Conclusions: Polish patients participating in the study have a positive attitude towards the implementation of vaccination services in community pharmacies as an effective way of combating infectious diseases.

Osteoporosis is characterized by the reduction of bone mineral density and the weakness of the bone strength leading to fractures. Searching for new compounds that stimulate bone activity and their ability to reconstruct seems to be a promising tool in osteoporosis treatment. Here, we performed analyses comparing the impact of polyrhodanine (PRHD) and its derivatives on the viability (anti-proliferative tests), morphology and mitochondrial network (confocal microscopy) towards pre-osteoblasts (MC3T3-E1 cell line) and osteoclasts (4B12 cell line). Moreover, we assessed the expression of genes associated with the apoptosis, inflammation and osteogenic differentiation by qPCR technique. Our results clearly demonstrated that PRHD and its modification at ratio 10/90 significantly improves the pre-osteoblast’s proliferative abilities, while reducing osteoclast function. The observed effects were strongly correlated with the cytoskeleton and mitochondrial network development and arrangement. Additionally, the expression profile of genes revealed enhanced apoptosis of osteoclasts in the case of PRHD and its modification at ratio 10/90. Moreover, in this case we also observed strong anti-inflammatory properties demonstrated by decreased expression of Il1b, Tnfa and Tgfb in pre-osteoblasts and osteoclasts. On the other hand, enhanced expression of the markers associated with bone remodeling, namely, osteopontin (OPN), osteocalcin (OCL) and alkaline phosphatase (ALP), seem to confirm the role of PRHD@MnFe2O4 in the promotion of differentiation of pre-osteoblasts through the ALP-OPN-OCL axis. Based on these observations, PRHD@MnFe2O4 could be a potential agent in osteoporosis treatment in future, however, further studies are still required.
