In addition to regular healthcare and nutrition delivery, their revised responsibilities included screening for COVID-19, contact tracing, communication of preventative measures, adapting nutrition-related programmes, and doorstep delivery of maternal and child health services. In this report, the Accountability Initiative (AI) at the Centre for Policy Research (CPR) highlights the oft-overlooked stories of government functionaries at the frontline of COVID-19 response since the advent of the initial lockdown. The overall objectives covered in this report are: 1. Understanding the evolving role of FLW workers during the pandemic and the impact of COVID work on their regular duties. 2. Gaining insight into the processes and best practices for training, implementation and supportive supervision

The Development and Validation of a Novice Nurse Decision-Making Skills Education Curriculum

Novice nurses (NNs) are entering critical care environments with limited knowledge, skills, and decision-making expertise. They are expected to care for complex patients in a dynamic healthcare setting. The research question for this project examined whether NNs improve their knowledge and skills by participating in a nursing decision-making skills curriculum. The purpose of the project was to develop and validate a nursing decision-making skills education curriculum working in an intermediate critical care unit. Taba\u27s instructional theoretical model was used to guide the new curriculum development along with current evidence based practice found in the current literature. Scaffolding approach theory encouraged the use of more knowledgeable peers or educators to assist NN with skill acquisition. Project participants consisted of 5 local learning specialists in critical-care nursing with a minimum of a bachelor\u27s of science degree in nursing as well as national certifications. Upon curriculum review completion, each of the 5 specialists were asked to complete a 5-point Likert scale survey to evaluate the content of the newly developed curriculum. Descriptive analysis was completed on the survey data. Three of the 5 learning specialists agreed and 2 strongly agreed that the program met its stated objectives. Three of the learning specialists strongly agreed and 2 agreed that the course content was relevant to NNs\u27 day-to-day roles and that the material and resources facilitated the development of decision-making skills. Adjunct NN education may promote positive social change by providing an effective strategy for improving decision-making skills among NNs, potentially leading to improved patient outcomes in a healthier community with a skilled healthcare workforce

A Critical Analysis of Kushthaghna Dravyas Mentioned in Sushrutokta Gana with Commentators View on Controversial Drugs

Ayurveda is one of the oldest medical systems with a holistic approach to health and individualize medicine. All the skin diseases in Ayurveda have been discussed under the broad heading of Kushtha. The literal meaning of Kustha is “Kushnati tad vapuhu” which means the Roga which causes discoloration, disfiguration. Acharya Charaka, Sushruta, and Vaghbhata mentioned Kushthghna Dravyas (drugs acting on skin diseases) in their books respectively. Sushruta Samhita is one of prime compendium of Ayurveda where various categorization (Gana) of drugs acting according to different ailments is mentioned in Sutrasthana 38th chapter named Dravyasangrehniya-adhyaya. The objective of the present article is to study the drugs which are mentioned in the category of the drugs which acts on Kushtha (Kushthghna), with their chemical constituents, and pharmacological actions with special reference to Sushruta Samhita and other related books. Rasa-panchaka, botanical names with family, contraversial identification according to commentator’s views are also discussed for better understanding of Dravyas. The review concluded that herbs mentioned in Ayurveda (Sushrutokta Gana) are beneficial in skin diseases and cosmetics in one or another way and also this article will help Ayurvedic UG/PG students, PhD scholars and Ayurveda physicians in both academics and clinical aspect

Effect of coronavirus disease 2019 pandemic on spinal surgery patients: Our experience at a tertiary care center

Introduction: In December 2019, a cluster of atypical cases of pneumonia was reported in Wuhan, China, which was later designated as Coronavirus disease 2019 (COVID-19) by the World Health Organization (WHO) on Feb 11, 2020. We all are facing a global pandemic, and it is very important to be clear that there is no correct roadmap to navigate this difficult situation. It is imperative to state that this global pandemic impacted the spine care services of our institute. In the present study, we have assessed the spine surgeries performed by orthopedic surgeons in terms of volume and etiologies during the COVID-19 pandemic and compared the data with a pre-COVID period. Materials and Methods: We retrospectively collected data from all patients who underwent spinal surgeries at our institute under the department of orthopedics from August 20, 2019 to August 20, 2020 (a total of 12 months duration). The data was then divided into two groups—pre-COVID period (August 20, 2019–February 19, 2020—6 months) and during the COVID pandemic (February 20, 2020–August 20, 2021—6 months). Results: A total of 140 patients underwent surgery at our institute from August 20, 2019 to August 20, 2020. Of these, 91 patients underwent surgery during the pre-COVID period, and 49 patients underwent surgery during the COVID pandemic. In this devastating phase of the pandemic, our department's total number of surgeries significantly declined to 46.15%. The routine surgeries performed during the pandemic phase show a steep fall from 59.34% in the pre-COVID period to 10.20%. Conclusion: This paper is meant to focus attention on the exorbitant reduction in the operative workflow of the spine patients during the COVID-19 pandemic at a tertiary healthcare institute. It is the need of the hour that orthopedic surgeons maintain equilibrium while providing the best possible treatment to their patients and limiting the spread of the COVID-19 pandemic

Prevalence of vero toxic Escherichia coli in fecal samples of domestic as well as wild ruminants in Mathura districts and Kanpur zoo

Aim: The present study was planned to reveal the prevalence of verocytotoxigenic Escherichia coli (VTEC) in fecal samples of domestic and wild ruminants in Mathura district and Kanpur zoo. Materials and Methods: A total of 240 fecal samples comprising 60 each of cattle, buffalo, sheep and deer from Mathura districts and Kanpur zoo were screened for the presence of E. coli and VTEC genes positive by polymerase chain reaction (PCR). Result: Out of 240 fecal samples, 212 E. coli strains were obtained. All the E. coli isolates were screened by PCR to detect virulence genes stx1, stx2, eaeA and hlyA. Of these, 25 isolates were identified as VTEC. The prevalence of VTEC in cattle, buffalo, sheep and deer was found 13.4% (8/60), 13.4% (8/60), 6.67% (4/60) and 8.33% (5/60), respectively. Conclusion: stx1, stx2, eaeA and hlyA genes were prevalent in VTEC isolates from feces of cattle, buffalo, sheep and deer population of Mathura districts and Kanpur zoo. The presence of VTEC isolates in this region may pose a threat to public health

Occurrence of multidrug resistant Escherichia coli in groundwater of Brij region (Uttar Pradesh) and its public health implications

Aim: The study evaluates the microbial as well as physicochemical pollution of groundwater of Brij region of Uttar Pradesh, a major tourist destination in the country along with estimating the drug resistance evident in the isolated Escherichia coli. Materials and Methods: A total of 60 samples of groundwater were collected from six different sites and assessed for physicochemical (pH, color, taste, turbidity, total dissolved solids [TDS], total hardness [TH], chlorides, fluorides, nitrates, and iron) and microbiological parameters (standard plate count [SPC], most probable number test [MPN], E. coli). Results: A majority of the samples were found to be out of the range for most of the parameters except iron. Particularly, high values of TDS (up to 9000 ppm), TH (1500 mg/L), chlorides (3250 mg/L), fluorides (2.5 mg/L), and nitrates (100.2 mg/L) were observed at most of the sites in the region highlighting the fact that groundwater of the area is not potable. Samples were turbid and salty to taste. High SPC values, up to 3500 colony-forming unit/ml and coliforms beyond BIS range were found in 40% samples suggesting gross microbial contamination. Only 2 sites (G3 and G5) had low MPN values. Overall 16 (26.67%) E. coli were isolated with 3 (18.75%) producing red colonies on conge red agar, hence supposed to be pathogenic. No E. coli O157:H7 was isolated. High antimicrobial resistance was observed against amoxicillin and erythromycin, whereas E. coli isolates were sensitive toward cefotaxime-clavulanic acid and imipenem. 12 isolates (75%) were multidrug resistant (MDR) with MDR index >20%, and 2 isolates (12.5%) were found to be extended spectrum beta-lactamases positive. Conclusion: Groundwater is considered to be a safe option for potable water but it is obvious from the findings of this study that considerable physicochemical and microbial contamination is there in groundwater samples of Brij region. The occurrence of MDR E. coli in these waters is a matter of great public health concern
