The current work was aimed to revealed the preoperative ondansetron and ephedrine requirements during spinal anesthesia for cesarean sections. The study is a randomized, single-blind clinical trial. From April 2023 to April 2024, the study was conducted in Al-Shifa Private Hospital in Baqubah, Diyala. The current study comprised a total of 135 pregnant women who were scheduled for a caesarian section under spinal anesthesia. The women were placed into three equal groups at random, with Group N serving as the control group and receiving 10 mL of 0.9% normal saline with or without ephedrine. Ephedrine 10 mg was given to Group E, diluted to 10 mL in 0.9% normal saline. Ondansetron 8 mg was given to Group O, either with or without ephedrine, and diluted to 10 mL in 0.9% normal saline. The mean systolic and diastolic blood pressure at baseline readings did not differ substantially (P>0.05); however, during follow-up, the ondansetron group's blood pressure was significantly higher than the ephedrine groups. In terms of heart rate, the mean heart rate for both drugs was not significant different at baseline (P>0.05); however, during follow-up, the ephedrine group's heart rate was significantly greater than the ondansetron groups. Additionally, the results demonstrate that shivering was observed in 14(10.4%) patients in the saline group and 3(2.2%), 6(4.4%), and 6(4.4%) subjects in the Ondansetron and Ephedrine groups, respectively (P=0.041). Regarding bradycardia and discomfort, the three groups also did not significantly change (P>0.05). The saline group experienced a considerably higher rate of nausea and vomiting (15.6%) in comparison to the ephedrine (9.6%) and Ondansetron (3.0%) groups (P=0.001). Bradycardia was observed in the saline group at 3.0%, whereas it was 1.5% in the ephedrine group and 0.0% in the Ondansetron group (P=0.071). In the saline group (14.1%), ephedrine was required substantially more than in the Ondansetron group (1.5%; P=0.001). Our findings indicate that administering ephedrine 10 mg or ondansetron 8 mg just after spinal anesthesia during an elective cesarean delivery can significantly impact the mother's blood pressure, heart rate, and other related issues, ondansetron reduces the need for ephedrine during operation.

Enterococcus faecalis is common in rebellious endodontic Infections, it can form biofilms that withstand antimicrobials treatments which may be very important in preventing the resistance against endodontic medicament.  The introduction of nanotechnology in dentistry intra canal therapy may become more effective against the causative agents of endodontic infections. The present in vitro investigation aimed to determine the antibacterial action of two nanoparticle solutions against   E. faecalis compared with routine endodontic irrigations Chlorohexidine (CHX) and Sodium hypochlorite NaOCl. After being infected with E. faecalis, thirty human mandibular molars were treated with Chitosan nanoparticles(Cs-NPs), titanium dioxide nanoparticles (TiO2-NPs), Chlorohexidine and Sodium hypochloride. Colony forming units (CFU) were utilized to compare between the antimicrobial effect of traditional & new medications. All tested medicaments reduced bacterial counts and the largest percentages were found in (Cs-NPs) and (Cs-NPs + CHX ) with a significant difference of <0.05.

The risk factors associated with Type 1 Diabetes Mellitus (T1DM) in children and adolescents are multifaceted and involve a complex interplay of genetic predisposition and environmental triggers. Early derangements such as glucose fluctuations and genetic variations in genes like INS and PTPN22 have been identified as predictive factors for T1DM development. Environmental factors including viral infections, parasitic exposures and family dynamics also play a significant role in the pathogenesis of T1DM. Understanding these risk factors is crucial for developing effective preventive strategies. However, challenges exist in studying T1DM due to its heterogeneous nature and the need for more comprehensive data collection. This review highlights the importance of further research in elucidating the mechanisms underlying T1DM development and emphasizes the need for tailored interventions to mitigate the increasing rates of T1DM in childhood and adolescence.

Antimicrobial resistance (AMR) represents a significant threat to global public health, characterized by the ability of microorganisms to withstand antimicrobial treatments, rendering standard therapies ineffective.  Aim: To provide an in-depth understanding of the mechanisms underlying bacterial resistance to antimicrobial agents, highlighting historical discoveries, types of resistance, factors influencing resistance development, and strategies to combat AMR. Material and Methods: A comprehensive literature review and analysis of various resistance mechanisms, including intrinsic and acquired resistance, gene transfer, and the role of efflux pumps and enzymatic destruction. Observations and results: The complexity of resistance mechanisms and the rapid evolution of resistant strains.  Discussion: The research emphasizes the need for rational drug use, stringent infection control practices, and robust antimicrobial surveillance. In conclusion, tackling AMR requires a multifaceted approach, combining scientific research, public health initiatives, and global cooperation

Background: Hypertension, commonly known as high blood pressure, is a significant global public health concern and a leading risk factor for cardiovascular diseases, stroke and renal failure. Despite its serious implications, hypertension is often under-diagnosed and inadequately managed, particularly in developing regions. In India, the burden of hypertension is rapidly increasing due to urbanization, lifestyle changes and dietary habits. This study aims to gauge awareness and knowledge about hypertension among the general public in District Shimla, Himachal Pradesh. Materials and Methods: A descriptive, cross-sectional survey design was employed, targeting adults aged 18 and above who had been residents of District Shimla for a minimum of 12 months. A robust sample size of 400 adults was determined using a 95% confidence level and an estimated knowledge level of 50% regarding hypertension. Data collection was conducted through a Google Form questionnaire circulated via online modes. The questionnaire included demographic data and 20 structured knowledge-related questions about hypertension. Data analysis was performed using Epi Info V7 Software. Results: The study population comprised 400 respondents with diverse socio-demographic backgrounds. The age distribution revealed that 39% were over 50 years old. Males constituted 54.5% of the sample. The majority 62% were married and 80.5% identified as Hindu. Employed individuals made up 50.5% of the respondents. Education levels varied, with 36.75% holding graduate degrees. Awareness regarding basic concepts of hypertension was high, with 80.75% correctly identifying "What is hypertension?" and 78% knowing normal blood pressure values. However, significant gaps were found in knowledge about hereditary factors 48.25% and the role of medication 45.5%. Overall knowledge scores were categorized as Very Good 20.75%, Good 30.5%, Fair 24% and Poor 24.75%. Conclusion: The findings highlight critical gaps in specific knowledge areas about hypertension among the public in Shimla. There is an urgent need for tailored public health interventions focusing on comprehensive hypertension management, including lifestyle changes, regular monitoring and medication adherence. Enhanced educational campaigns leveraging local resources and digital platforms are essential to bridge these gaps and improve cardiovascular health in the region.
