Circulating miRNA-21 Levels in Breast Cancer Patients Before and After Chemotherapy and Its Association with Clinical Improvement.

Breast cancer is the most frequent type of cancer in women, many patients experience recurrences and metastasis. miR-21 (microRNA-21) as biomarker is under investigation for breast cancer. At present, there is very limited information available regarding effect of chemotherapy on miR-21 expression in breast cancer and its correlation with the clinical improvement. Hence, this study was planned to evaluate the effect of chemotherapy on miR-21 in metastatic breast cancer and its relationship with the clinical outcome. Females, aged-18-90 years diagnosed with Invasive Ductal Carcinoma of breast and candidate of neoadjuvant chemotherapy including Adriamycin (60 mg/m2), Cyclophosphamide (600 mg/m2) with or without Taxane (75-175 mg/m2) were included in the study. Before and after 42 days of staring of chemotherapy sample was collected for circulatory miR-21 and RECIST 1.1 criteria was applied to assess the clinical status. Blood samples for routine clinical biomarkers including liver function test and renal function tests was also collected. miR-21 expression before and after chemotherapy was assessed using standard method based on real time PCR. Expression of miR-21, RECIST criteria and other liver and kidney related biomarkers were compared before and after chemotherapy. After neoadjuvant chemotherapy expression of miR-21 was significantly increased by 5.65-fold. There was significant improvement in clinical scores based on RECIST criteria (0.046). No significant correlation was observed between miR-21 expression and difference in RECIST score (r = - 0.122, p = 0.570). Neoadjuvant chemotherapy causes clinical improvement in breast cancer patients however it is not correlated with the miR-21 expression which significantly increased after chemotherapy.

Shoulder Injury Related to Vaccine Administration (SIRVA) with COVID-19 vaccination - A case report.

The case report evaluates shoulder injury related to COVID-19 vaccine administration. A 26-year-old female patient presented with shoulder pain, which increased on extension and overhead abduction in routine work. Magnetic resonance imaging (MRI) was done based on which, a diagnosis of shoulder injury related to vaccine administration (SIRVA) was reported. Significant improvement was seen after Non-steroidal anti-inflammatory drugs (NSAIDs), topical diclofenac ointment, and serratiopeptidase tablets. Physical muscle strengthening exercises were advised. Based on Naranjo and World Health Organization (WHO) casualty assessments, the adverse drug reaction (ADR) was categorized under probable. Preventability, Hartwig's scales for severity was assessed, which showed preventability and moderate grade in severity. The total cost (direct and indirect) for management was found to be rupees 7021 and 41,781 in government and private hospital respectively. Thus ADRs not only add to patient suffering but also increase the economic burden. Health care professionals (HCPs) need to be made aware of potentially fatal ADRs associated with the administration of vaccines and should be keen to report such ADRs to drug safety authorities.

Demand of COVID-19 medicines without prescription among community pharmacies in Jodhpur, India: Findings and implications.

Background: COVID-19 pandemic led to increased self-medication of antimicrobials, vitamins, and immune boosters among the common people and consuming without prescription can lead to adverse consequences including antimicrobial resistance. Methods: A cross-sectional study was conducted on community pharmacies in Jodhpur, India. They were inquired regarding the prescription and increased sales (<25%, 25-50%, 50--75%, or 75--100%) of various medicines (Hydroxychloroquine, Azithromycin, Ivermectin, and Vitamin C) during the COVID-19 pandemic. Logistic regression analysis was conducted to assess the relationship between requests for certain COVID-19 medications and an increase in their sale. Results: A total of 204 pharmacies took part, and 88.23% reported patients to approach them without prescriptions. Most of the pharmacies revealed that <25% of patients came without prescription. The majority came for azithromycin (68%) and vitamin C (92%). Increased sales of the four targeted medications were seen by 85.92% of pharmacies compared to last year. A majority (51.5%) reported <25% increased sales of azithromycin, but no change in the sale of hydroxychloroquine and ivermectin. However, 39.6% reported >75% increase in vitamin C sales. Conclusion: There was an increase in the demand for COVID-19 medications without prescription. This study was unable to detect a significant increase in sales of antimicrobials, which is encouraging.
