Traumatic Injury among Patients Presenting to the Department of Emergency Medicine of a Tertiary Care Centre.

Introduction: The majority of trauma-related deaths occur in low- and middle-income countries; however, limited data exists in these settings related to injury types and severity. The prevalence of trauma similar to our setting was less estimated. This study aimed to find the prevalence of traumatic injury among patients presented to the department of emergency medicine of a tertiary care centre. Methods: This is a descriptive cross-sectional study conducted among patients presented to the Department of Emergency Medicine from 15 September 2021 to 14 September 2022. Ethical approval was taken from the Institutional Review Committee. World Health Organization trauma minimum data set, injury mechanism, types and patient disposition data were collected and injury severity scores were calculated. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 47,825 patients, 1,524 (3.19%) (3.03-3.34, 95% Confidence Interval) patients presented with a traumatic injury. A total of 967 (63.45%) were males and had a median age of 30 years (Interquartile range: 25). Most injuries were caused by falls 650 (42.65%), followed by road traffic accidents 411 (26.97%). A majority had minor Injury Severity Scores 1280 (83.99%). Conclusions: The prevalence of traumatic injury among patients presenting to emergency was found to be lower than other studies done in similar settings. Keywords: emergency care; injuries and wounds; injury severity score; trauma unit.

Dual targeted 2-Benzylideneindanone pendant hydroxamic acid group exhibits selective HDAC6 inhibition along with tubulin stabilization effect.

Abnormal epigenetics has been recognised as an early event in tumour progression and aberrant acetylation of lysine in particular has been understood in tumorigenesis. Therefore, it has become an attractive target for anticancer drug development. However, HDAC inhibitors have limited success due to toxicity and drug resistance concerns. Present study deals with design and synthesis of bivalent indanone based HDAC6 and antitubulin ligands as anticancer agents. Two of the analogues 9 and 21 exhibited potent antiproliferative activities (IC50, 0.36-3.27 µM) and high potency against HDAC 6 enzyme. Compound 21 showed high selectivity against HDAC 6 while 9 exhibited low selectivity. Both the compounds also showed microtubule stabilization effects and moderate anti-inflammatory effect. Dual targeted anticancer agents with concomitant anti-inflammatory effects will be more attractive clinical candidates in future.

Intravenous administration of viral vectors expressing prostate cancer antigens enhances the magnitude and functionality of CD8+ T cell responses.

BACKGROUND: The use of immunotherapeutic vaccination in prostate cancer is a promising approach that likely requires the induction of functional, cytotoxic T cells . The experimental approach described here uses a well-studied adenovirus-poxvirus heterologous prime-boost regimen, in which the vectors encode a combination of prostate cancer antigens, with the booster dose delivered by either the intravenous or intramuscular (IM) route. This prime-boost regimen was investigated for antigen-specific CD8+ T cell induction. METHODS: The coding sequences for four antigens expressed in prostate cancer, 5T4, PSA, PAP, and STEAP1, were inserted into replication-incompetent chimpanzee adenovirus Oxford 1 (ChAdOx1) and into replication-deficient modified vaccinia Ankara (MVA). In four strains of mice, ChAdOx1 prime was delivered intramuscularly, with an MVA boost delivered by either IM or intravenous routes. Immune responses were measured in splenocytes using ELISpot, multiparameter flow cytometry, and a targeted in vivo killing assay. RESULTS: The prime-boost regimen was highly immunogenic, with intravenous administration of the boost resulting in a sixfold increase in the magnitude of antigen-specific T cells induced and increased in vivo killing relative to the intramuscular boosting route. Prostate-specific antigen (PSA)-specific responses were dominant in all mouse strains studied (C57BL/6, BALBc, CD-1 and HLA-A2 transgenic). CONCLUSION: This quadrivalent immunotherapeutic approach using four antigens expressed in prostate cancer induced high magnitude, functional CD8+ T cells in murine models. The data suggest that comparing the intravenous versus intramuscular boosting routes is worthy of investigation in humans.

Inactivation of foot-and-mouth disease virus A/IRN/8/2015 with commercially available lysis buffers.

Laboratories working with foot-and-mouth disease virus (FMDV) must maintain a high level of biocontainment. However, if infectious virus is reliably inactivated during sample processing, molecular and serological testing can be performed at a lower level of containment. In this study, three commercial lysis buffers (AL, AVL, and MagMAX CORE) were tested in two laboratories for their ability to inactivate FMDV A/IRN/8/2015 in different sample matrices (cell culture supernatant, epithelial tissue suspension and milk). Residual infectivity after the addition of lysis buffer was evaluated by inoculating susceptible cell cultures. No cytopathic effect was observed for all three lysis buffers, indicating that the buffers are capable of reducing viral infectivity (estimated range 3.1 to >5.1 Log10). These results highlight the capacity of lysis buffers to decrease FMDV infectivity; however, additional validation experiments should be conducted, particularly if different sample matrices and/or lysis buffers are used.

Factors associated with utilization of adolescent-friendly services in Bhaktapur district, Nepal.

BACKGROUND: The status of adolescent sexual and reproductive health (SRH) in Nepal is alarming. Adolescent-friendly services (AFS) were introduced to cater the health needs of adolescents. Optimal utilization of the services with wider accessibility is required to prevent adolescents from adopting life-threatening behaviors that result in poor SRH-related outcomes. Despite the upgrading of health facilities to adolescent-friendly sites, studies reveal low utilization of the service. However, these studies failed to explore the factors influencing the low levels of service utilization in these adolescent-friendly facilities. This study quantified the utilization of AFS and identified factors associated with its utilization among adolescents of Bhaktapur district. METHODS: A cross-sectional survey of 362 systematic randomly selected adolescents from four village development committees of Bhaktapur district was conducted, using a self-administered questionnaire. Relationships between utilization of AFS and associated factors were determined by multivariate logistic regression at a level of significance with a p value of less than 0.05 and adjusted odds ratio. Key informant interviews and focus group discussions with adolescents were used to collect qualitative data which were then described using thematic analysis. RESULT: About a quarter (24.7%) of the respondents had utilized the adolescent-friendly services. Factors positively associated with the utilization of services included adolescents aged 15-19 years, female, heard about AFS, lack of fear of being seen while getting SRH services, lack of shyness about receiving SRH services, and the perceived need for SRH services as soon as illness became apparent. The qualitative findings revealed lack of awareness about the services, socio-cultural barriers, confidentiality, feasible service hours, and the preference for of same-sex service providers as the factors affecting utilization. CONCLUSION: The utilization of adolescent-friendly services was very low in Bhaktapur district. Most of the adolescents were unaware of the existence of the AFS which emphasizes the need to focus on the increasing awareness of SRH and AFS by the government in coordination with local schools, clubs, etc. Creating an enabling environment in the service delivery sites, and ensuring privacy and confidentiality, as well as ensuring same-sex service providers and feasible service hours to adolescents, could increase the service utilization.

The present and future role of ultrasound targeted microbubble destruction in preclinical studies of cardiac gene therapy.

Multiple limitations for cardiac pharmacologic therapies like intolerance, individual variation in effectiveness, side effects, and high cost still remain, despite the recent progress in diagnosis and health support. Gene therapy is poised to be an attractive alternative in various ways for the future, refractory cardiac diseases being one aspect of it. As a novel therapy to deliver the objective gene to organs of living animals, ultrasound targeted microbubble destruction (UTMD) has therapeutic potential in cardiovascular disorders. UTMD, which binds microbubbles with DNA or RNA carriers into the shell and destroys the located microbubbles with low frequency and high mechanical index ultrasound can release target agents to specific organs. UTMD has the ability to transfect markedly through sonoporation, cavitation and other effects by way of intravenous injection that is minimally invasive and highly specific for gene deliverance. Here, we have summarized the present role of UTMD in pre-clinical studies of cardiac gene therapy which covers myocardial infarction, regeneration, ischaemia/reperfusion injury, hypertension, diabetic cardiomyopathy, adriamycin cardiomyopathy and some discussion for further studies.

Health care workers' knowledge, attitudes and practices on tuberculosis infection control, Nepal.

BACKGROUND: Infection control remains a key challenge for Tuberculosis (TB) control program with an increased risk of TB transmission among health care workers (HCWs), especially in settings with inadequate TB infection control measures. Poor knowledge among HCWs and inadequate infection control practices may lead to the increased risk of nosocomial TB transmission. METHODS: An institution-based cross-sectional survey was conducted in 28 health facilities providing TB services in the Kathmandu Valley, Nepal. A total of 190 HCWs were assessed for the knowledge, attitudes and practices on TB infection control using a structured questionnaire. RESULTS: The level of knowledge on TB infection control among almost half (45.8%) of the HCWs was poor, and was much poorer among administration and lower level staff. The knowledge level was significantly associated with educational status, and TB training and/or orientation received. The majority (73.2%) of HCWs had positive attitude towards TB infection control. Sixty-five percent of HCWs were found to be concerned about being infected with TB. Use of respirators among the HCWs was limited and triage of TB suspects was also lacking. CONCLUSIONS: Overall knowledge and practices of HCWs on TB infection control were not satisfactory. Effective infection control measures including regular skill-based training and/or orientation for all categories of HCWs can improve infection control practices in health facilities.

Risk of ARI among Non-exclusively Breastfed Under-Five Passive Smoker Children: A Hospital-Based Cross-sectional Study of Nepal.

BACKGROUND: As Nepal witnesses high burden of both acute respiratory infection (ARI) and passive smoking among under-five children, studies on effect modification of exclusive breastfeeding on passive smoking and ARI carry huge significance. With Nepal holding no evidence in this regard, findings would be useful to promote a cost-effective intervention: exclusive breastfeeding. This study was therefore conceived as an effort to bring to light the modifying effect that exclusive breastfeeding may have on the association between household passive smoking and ARI among under-five children. METHODS: One hundred and ninety-eight parents of under-five children from Kanti Children's Hospital, Kathmandu, Nepal, participated in this descriptive, cross-sectional study carried out in October 2012. Data collected from a semi-structured questionnaire were subjected to univariate, bivariate, and multivariable analysis in R version 3.1.2. RESULTS: Non-exclusively breastfed children with presence of anyone smoking at their house [aOR = 4.8, 95% confidence interval (CI): 1.7-13.2] and smoking in presence of children (aOR = 6.4, 95% CI: 1.1-38.3) had higher chances of ARI; nevertheless, this remained insignificant among the exclusively breastfed ones. Having a separate kitchen in the house showed protective effect against ARI among exclusively breastfed children (aOR = 0.2, 95% CI: 0.1-0.6). Children whose mothers spent at least 2 h per day in the kitchen had a higher chance of developing ARI, regardless of being exclusively breastfed (aOR = 4.5, 95% CI: 1.5-13.1) or non-exclusively breastfed (aOR = 4.5, 95% CI: 1.4-14.2) compared to those who spent <2 h per day. CONCLUSION: Non-exclusive breastfeeding may increase the chances of deleterious effects of household passive smoking, such as ARI, among under-five children. As these findings are not conclusive, studies with better design and larger samples are warranted to confirm the effect.
