RESUMO
Background: Oral care is one of the fundamental nursing care procedures used to decrease oral colonization, dental plaque, respiratory infections, patient stay, and cost. The importance of good oral hygiene for patients in intensive care units (ICUs) is well recognized, however, the most effective way to achieve good oral care in the ICU is unclear. Therefore, the aim of this study was to assess the knowledge, attitude, and practice of nursing professionals regarding oral healthcare in ICUs among various medical institutes across India. Materials and methods: A questionnaire-based multicentric cross-sectional survey was conducted among registered nursing professionals employed at ICUs of three government tertiary healthcare centers (THC) of India: THC-I, THC-II, and THC-III located in the eastern and northern parts of India between February 2022 and July 2022. Results: A total of 150 nurses completed the questionnaire form (response rate: 62.5%) comprised of 49 (32.7%) males and 101 (67.3%) females with a mean age of 35.69 ± 7.7 years. Nursing officers' knowledge surpassed that of staff nurses regarding the duration of toothbrushing (p = 0.033). Among interinstitutional comparisons, THC-I nurses showed the greatest knowledge regarding the duration of toothbrushing and the mechanism of preventing saliva accumulation to reduce microbial growth (p = 0.013 and p = 0.003, respectively). Based on total work experience, participants were segregated into three groups: Group I (<7 years), group II (7.1-13.9 years), and group III (>14 years). Group II surpassed the knowledge of denture removal during sleep, cleaning after every meal, and storing in personalized air-tight containers (p = 0.001 and p = 0.036, respectively). The majority from group II recommended plain saline as the material for oral hygiene maintenance in ICU patients (p = 0.008). Group III predominantly practiced the ideal handwashing technique pre- and post-patient contact which was statistically significant (p = 0.001). Conclusion: This study observed that a knowledge gap exists among the nurses of the three institutes across India pertaining to the oral hygiene care of ICU patients. Nurse's education and implementation of the proper oral hygiene measures for intubated patients in ICU setup is an essential need.

RESUMO
Background: Oral cancer screening reduces mortality associated with oral cancer. The current study evaluated the cost-effectiveness of commonly used screening techniques, namely conventional oral examination (COE), toluidine blue staining (TBS), oral cytology (OC), and light-based detection (LBD) in the Indian scenario. Methods: The study used a Markov modelling approach to estimate the cost and health outcomes of four different approaches (COE, TBS, OC, and LBD) for screening oral cancer over time from a societal perspective. The discount rate was assumed as 3%. The outcomes estimated were oral cancer incident cases, deaths averted, and quality-adjusted life years (QALYs). To address the high burden of risk factors (tobacco and/or alcohol) in India, two Markov models were developed: Model A adopted a mass-screening strategy, whereas Model B adopted a high-risk screening strategy versus no screening. Probabilistic sensitivity analysis (PSA) was undertaken to address any parameter uncertainty. Findings: Mass-screening using LBD at three years had the least incident cases (3271.68) and averted the maximum number of oral cancer deaths (459.76). High-risk screening using COE at ten years interval incurred the least lifetime cost of 2,292,816.21 US$ (182,794,468.26 INR). The high-risk strategies (US$/QALY), namely COE 5 years (-29.21), COE 10 years (-90.68), TBS 10 years (-60.54), and LBD 10 years (-13.51), were dominant over no-screening. Interpretation: The most cost-saving approach was the conventional oral examination at an interval of 10 years for oral screening in high-risk populations above 30 years of age.

RESUMO
BACKGROUND: The pathogenesis of portal vein thrombosis (PVT) in cirrhosis is multifactorial, with altered hemodynamics being proposed as a possible contributor. The present systematic review was conducted to study the role of assessment of portal hemodynamics for the prediction of PVT in patients with cirrhosis. METHODS: Three databases (Medline, Embase, and Scopus) were searched from inception to February 2023 for studies comparing portal venous system parameters in patients with cirrhosis developing PVT with those not. Results were presented as mean difference (MD) or odds ratio (OR) with their 95% confidence intervals (CIs). RESULTS: A total of 31 studies (patients with cirrhosis: 19 studies, patients with cirrhosis undergoing splenectomy: 12 studies) were included. On pooling the data from multivariable analyses of the included studies, a larger portal vein diameter was a significant predictor of PVT in patients with cirrhosis without or with splenectomy with OR 1.74 (1.12-2.69) and OR 1.55 (1.26-1.92), respectively. On the other hand, a lower portal vein velocity (PVV) was a significant predictor of PVT in cirrhotics without or with splenectomy with OR 0.93 (0.91-0.96) and OR 0.71 (0.61-0.83), respectively. A PVV of <15 cm/s was the most commonly used cut-off for the prediction of PVT. Patients developing PVT also had a significantly higher splenic length, thickness, and splenic vein velocity. CONCLUSION: The assessment of portal hemodynamic parameters at baseline evaluation in patients with cirrhosis may predict the development of PVT. Further studies are required to determine the optimal cut-offs for various parameters.

Genome evolution of Mycobacterium tuberculosis (Mtb) produces new strains resistant to various pre-existing anti-tubercular drugs. Hence, there is an urgent need to explore potent compounds with the most negligible side effects and effective Mtb inhibition. Mtb PyrG (CTP synthase) is a crucial enzyme for the conversion of the uridine triphosphate (UTP) into cytidine triphosphate (CTP) and is essential for the growth of Mtb. Thus, in this study, phytochemicals of Withania somnifera (W. somnifera) were screened to find the potential inhibitors against Mtb PyrG. Molecular docking resulted in the identification of quercetin 3-rutinoside-7-glucoside, rutin, chlorogenic acid and isochlorogenic acid C with a substantial docking score (from -12.6 to -10.8 kcal/mol) contributed by significant intermolecular interactions. Furthermore, 100 ns molecular dynamics simulation, ADME analysis and free binding energy calculations support the stability of docked complexes and drug-likeness for selected compounds, respectively. Collectively, these findings suggest that phytochemicals present in W. somnifera can be considered for further evaluation against Mtb in a series of in vitro and in vivo models.Communicated by Ramaswamy H.

Background: Various attachments like ball, bar-clip, magnetic attachments are used in implant supported overdentures. Finite Element Analysis (FEA) a newly innovated technology has been used in dental implantology to evaluate stress distribution patterns. There is little evidence available regarding the stress distribution in peri-implant region for implant supported overdentures. The purpose of the review was to generate scientific evidence on peri-implant stress distribution in FEA model with different types of attachments employed in implant supported overdentures. Materials and methods: Systematic review was conducted as per the Preferred Reporting Items for Systematic Reviews Guidelines and Meta-Analyses statement (PRISMA). A comprehensive search was undertaken by two reviewers from January 2020 to June 2020 with no year limits to published articles. Only in-vitro FEA studies were included. Following electronic databases were searched for published studies- PubMed, Web of Science. Characteristics of the studies tabulated and analysis of articles was done to compare different attachment systems. Results: Locator attachments showed better stress distribution than ball attachment system in all the studies but one. Two studies showed results in favour of ball attachment compared to bar-clip attachment system when stress was evaluated distal to the implants. No significant difference in terms of stress concentration could be generated between ball versus magnetic/equator versus locator attachment system due to less number of studies and conflicting results. Conclusion: Various studies showed different results due to heterogenicity in selected attachment systems and study designs. Locator attachments showed favourable stress distribution around peri-implant bone than other attachments.
RESUMO
The advances in imaging techniques and growing awareness have increased the detection of nonpalpable breast lesions, which may be neoplastic or high-risk lesions. The standard technique of localizing these nonpalpable breast lesions is wire-guided biopsy/lumpectomy. However, wire-guided excision is fraught with the complications of migration, transection, patient discomfort, pneumothorax, vasovagal episodes, and injury to the radiologist, surgeon, and pathologist. We embarked upon a randomized controlled trial to compare the cost-effectiveness and patient-reported outcome (PRO) with hematoma-directed ultrasound-guided lumpectomy (HDUGL) versus conventional wire-guided lumpectomy (WGL) for nonpalpable breast lesions. This study was a parallel design, randomized controlled trial with a superiority hypothesis. Twenty-five patients could be randomized to wire-guided lumpectomy (WGL) group (n = 13) and hematoma-directed ultrasound-guided lumpectomy (HDUGL) group (n = 12). Post-excision specimen sonography and mammography for assessing adequacy of margin were done. A margin shave was performed in cases of close or suspicious margin on ultrasonography or mammogram. Both the groups were comparable in age, tumor size, histological subtypes, and location of lesions. The median resection volume in two groups was 34.5 (26.5) ml for HDUGL vs. 41 (15) ml for WGL. Intraoperative cavity shave was required only in the WGL group (n = 3.23%) and margin positivity was also more in the WGL group (n = 2,15.38%) as compared to the HDUGL group (n = 1,8.33%) but neither differences in cavity shave nor positive margins leading to re-operations were statistically significant. The difference in cost of surgery in two groups (INR 4680 ± 560.00 for HDUGL and INR 7486 ± 616.41 for WGL) was statistically significant (P = 0.00). Resultantly, HDUGL was more cost-effective (INR 5105.45) than WGL (INR 8847.09). Patients in the HDUGL group were more satisfied according to the Likert scale of 5 but this difference in two groups was not statistically significant (P = 0.07). The hematoma-directed ultrasound-guided lumpectomy (HDUGL) is better than wire-guided lumpectomy (WGL) for nonpalpable breast lesions in terms of cost-effectiveness.
