Insights from assessment for arrhythmia after CoViD-19 vaccination among Indians.

Post-vaccination myocarditis is usually moderate and transient, recovering quickly with conservative treatment. Therefore, it is of interest to assess for arrhythmia after CoViD-19 vaccination among Indians. We looked for ECG abnormalities in a small cohort of 50 participants after 52 weeks after receiving the Oxford/AstraZeneca CoViD-19 vaccination. Data shows that post-vaccination myocarditis is typically mild and transient, with most cases resolving swiftly through conservative management. Thus, it is unlikely that this vaccine will induce severe arrhythmias or life-threatening cardiac events in the general population.

Exploring the interplay of abstinence self-efficacy, locus of control, and perceived social support in substance use disorder recovery.

INTRODUCTION: Substance use disorder (SUD) poses a significant public health challenge globally, with substantial impacts on physical and social well-being. This study investigates the interplay between abstinence self-efficacy (ASE), locus of control (LOC), perceived social support (PSS), and various socio-demographic and psychosocial factors among individuals undergoing SUD rehabilitation. METHODS: Researchers obtained permission from drug rehabilitation centers in Assam, India, and conducted orientation programs for prospective participants. A total of 144 participants, aged 18-65 years, predominantly from rural areas participated in the study. Data was collected through one-to-one interviews, covering socio-demographic history, drug abuse, and administering scales for ASE, LOC and PSS. Collected data underwent digitization and subsequent descriptive and inferential statistical analyses. RESULTS: Significant associations were found between ASE and socio-demographic variables, family dynamics, and drug use history, highlighting the importance of considering these factors in SUD rehabilitation. Disturbed family relationships were linked to diminished ASE and higher risk of relapse, emphasizing the role of family support in recovery. Additionally, a negative correlation was observed between ASE and LOC, suggesting that individuals with higher ASE tend to have a more internal locus of control, which positively influences recovery outcomes. Moreover, positive correlations were found between ASE and PSS, particularly from family members, underscoring the importance of social support in fostering recovery. Regression analysis further elucidated the relationships between ASE, LOC, and PSS, emphasizing the predictive value of LOC and the impact of family support on ASE. CONCLUSION: Findings of this study have several implications for developing targeted interventions aimed at strengthening ASE, promoting internal locus of control, and enhancing social support systems.

Substance use disorder (SUD) is a major public health concern today, characterized by the compulsive and prolonged use of harmful psychoactive substances, leading to various physical and social dysfunctions. This study explores the relationships between abstinence self-efficacy (ASE), locus of control (LOC), perceived social support (PSS), and various socio-demographic factors in individuals undergoing SUD rehabilitation in Assam, India. The focus of the study is to find out various factors which can facilitate the process of drug rehabilitation. Data from 144 participants aged 18­65 were collected through interviews and standardized scales. Results indicate that ASE is significantly associated with socio-demographic variables, family dynamics, and drug use history. Disturbed family relationships were linked to lower ASE and higher risk of relapse, while a higher ASE was correlated with an internal LOC and greater PSS, especially from family. The study highlights the clinical significance of considering background factors like marital status, employment status, family relationship dynamics, and abstinence period in treatment planning to provide personalized care.

HRV changes in young adults with depression.

Background and Aims: Depression is a common and debilitant mental health disorder that is very common among young adults of the age group of 18-25 years. There is evidence that autonomic nervous system dysfunction associated with depression may play an important role in cardiovascular disease among patients with depression. HRV that is used to assess ANS function is found to be altered in depression. Since the HRV findings associated with depression remain inconsistent, this study is aimed to find HRV changes associated with depression so that the use of HRV as a diagnostic tool for depression can be validated. Methods: A total of 42 newly diagnosed patients of depression of the age group (18-26) years and 89 non-depressed volunteers matched for age, BMI and sex proportions were included in the study. Heart rate variability was recorded using five-minute stationary RR interval of Lead II by 4-channel Power Lab System (AD Instrument Ltd). HRV findings are summarized into Time-Domain parameters, Frequency-Domain parameters and Non-Linear parameters. Result: All HRV parameters are significantly reduced and the LF/HF ratio is significantly raised (P < 0.05) in the group of depressive patients when compared to the group of healthy controls. The reduction of HRV parameters (SDRR, RMSSD, Total Power, SD1 and SD2) in the group of patients with depression is found to be highly significant (P < 0.0001). Conclusion: The findings of our study suggest that depression may be associated with alterations in ANS activities, which contribute to an increased risk of cardiovascular disease. Thus, HRV can serve as a potential bio-marker for depression.

AI-based 3D-QSAR model of FDA-approved repurposed drugs for inhibiting sclerostin.

BACKGROUND: Wnt activation promotes bone formation and prevents bone loss. The Wnt pathway antagonist sclerostin and additional anti-sclerostin antibodies were discovered as a result of the development of the monoclonal antibody romosozumab. These monoclonal antibodies greatly increase the risk of cardiac arrest. Three-dimensional quantitative structure-activity relationships (3D-QSAR) predicts biological activities of ligands based on their three-dimensional features by employing powerful chemometric investigations such as artificial neural networks (ANNs) and partial least squares (PLS). OBJECTIVE: In this study, ligand-receptor interactions were investigated using 3D-QSAR Comparative molecular field analysis (CoMFA). Estimates of steric and electrostatic characteristics in CoMFA are made using Lennard-Jones and Coulomb potentials. METHODS: To identify the conditions necessary for the activity of these molecules, fifty Food and Drug Administration (FDA)-approved medications were chosen for 3D-QSAR investigations and done by CoMFA. For QSAR analysis, there are numerous tools available. This study employed Open 3D-QSAR for analysis due to its simplicity of use and capacity to produce trustworthy results. Four tools were used for the analysis on this platform: Py-MolEdit, Py-ConfSearch, and Py-CoMFA. RESULTS: Maps that were generated were used to determine the screen's r2 (Coefficient of Multiple Determinations) value and q2 (correlation coefficient). These numbers must be fewer than 1, suggesting a good, trustworthy model. Cross-validated (q2) 0.532 and conventional (r2) correlation values of 0.969 made the CoMFA model statistically significant. The model showed that hydroxamic acid inhibitors are significantly more sensitive to the steric field than the electrostatic field (70%) (30%). This hypothesis states that steric (43.1%), electrostatic (26.4%), and hydrophobic (20.3%) qualities were important in the design of sclerostin inhibitors. CONCLUSION: With 3D-QSAR and CoMFA, statistically meaningful models were constructed to predict ligand inhibitory effects. The test set demonstrated the model's robustness. This research may aid in the development of more effective sclerostin inhibitors that are synthesised using FDA-approved medications.

Background: AI in healthcare services is advancing every day, with a focus on uprising cognitive capabilities. Higher cognitive functions in AI entail performing intricate processes like decision-making, problem-solving, perception, and reasoning. This advanced cognition surpasses basic data handling, encompassing skills to grasp ideas, understand and apply information contextually, and derive novel insights from previous experiences and acquired knowledge. ChatGPT, a natural language processing model, exemplifies this evolution by engaging in conversations with humans, furnishing responses to inquiries. Objective: We aimed to understand the capability of ChatGPT in solving doubts pertaining to symptoms and histological features related to subject of oral pathology. The study's objective is to evaluate ChatGPT's effectiveness in answering questions pertaining to diagnoses. Methods: This cross-sectional study was done using an AI-based ChatGPT application that provides free service for research and learning purposes. The current version of ChatGPT3.5 was used to obtain responses for a total of 25 queries. These randomly asked questions were based on basic queries from patient aspect and early oral histopathologists. These responses were obtained and stored for further processing. The responses were evaluated by five experienced pathologists on a four point liekart scale. The score were further subjected for deducing kappa values for reliability. Result & Statistical Analysis: A total of 25 queries were solved by the program in the shortest possible time for an answer. The sensitivity and specificity of the methods and the responses were represented using frequency and percentages. Both the responses were analysed and were statistically significant based on the measurement of kappa values. Conclusion: The proficiency of ChatGPT in handling intricate reasoning queries within pathology demonstrated a noteworthy level of relational accuracy. Consequently, its text output created coherent links between elements, producing meaningful responses. This suggests that scholars or students can rely on this program to address reasoning-based inquiries. Nevertheless, considering the continual advancements in the program's development, further research is essential to determine its accuracy levels in future versions.

Effect of microbubble as local drug delivery system in endodontic management - An In-Vitro study.

Background and Objectives: Microbubbles (MBs) are gas or vapor-filled cavities inside liquids with sizes ranging from 2 to 3 µm. Recently, MBs have shown great promise in nanomedicine owing to their high encapsulation efficiency, targeted drug release, improved biocompatibility, and longer blood circulation. Furthermore, they are more suitable for focusing on particular body regions and are safer and non-invasive. MBs generators are used to create bubbles in fluid dynamics, chemistry, medicine, agriculture, and the environment. Drug delivery using MBs increases penetration without causing systemic toxicity. In this study, we examined whether the use of microbubbles as a local drug-delivery mechanism increases tubular penetration of endodontic medications and irrigant. Materials and Methods: An Enterococcus faecalis culture was added to 38 dentin cylinders of single-rooted teeth. Samples were divided into the experimental and control groups that received a triple antibiotic paste with and without MB infusion (n = 19 in each group), respectively. After 14 days, the number of live bacteria in the samples was determined using confocal laser scanning microscopy. Results: After 14 days of contact with the medication, the percentages of live and dead bacteria were assessed. Results show that Group 2 (Triple antibiotic infused micro bubble) showed significantly (P < 0.05) higher antibacterial efficacy than Group 1 (TAP). Conclusion: In this study, the antibacterial efficacy was significantly higher in the experimental group than in the control group. Therefore, within the limitations of the study it can be said that MB infusion is a viable technique to improve root canal disinfection. Hence, it can be considered as a novel technique for local drug delivery systems in endodontic management.

Efficacy of electronic apex locators in comparison with intraoral radiographs in working length determination- a systematic review and meta-analysis.

BACKGROUND: Successful endodontic treatment needs accurate determination of working length (WL). Electronic apex locators (EALs) were presented as an alternative to radiographic methods; and since then, they have evolved and gained popularity in the determination of WL. However, there is insufficient evidence on the post-operative pain, adequacy, and accuracy of EALs in determining WL. OBJECTIVE: The systematic review and meta-analysis aims to gather evidence regarding the effectiveness of EALs for WL determination when compared to different imaging techniques along with postoperative pain associated with WL determination, the number of radiographs taken during the procedure, the time taken, and the adverse effects. METHODS: For the review, clinical studies with cross-over and parallel-arm randomized controlled trials (RCTs) were searched in seven electronic databases, followed by cross-referencing of the selected studies and related research synthesis. Risk of bias (RoB) assessment was carried out with Cochrane's RoB tool and a random-effects model was used. The meta-analysis was performed with the RevMan software 5.4.1. RESULTS: Eleven eligible RCTs were incorporated into the review and eight RCTs into the meta-analysis, of which five had high RoB and the remaining six had unclear RoB. Following meta-analysis, no significant difference in postoperative pain was found among the EAL and radiograph groups (SMD 0.00, CI .29 to .28, 354 participants; P value = 0.98). Radiograph group showed better WL accuracy (SMD 0.55, CI .11 to .99, 254 participants; P value = 0.02), while the EAL group had 10% better WL adequacy (RR 1.10, CI 1.03-1.18, 573 participants; P value = 0.006). CONCLUSION: We found very low-certainty evidence to support the efficacy of different types of EAL compared to radiography for the outcomes tested. We were unable to reach any conclusions about the superiority of any type of EAL. Well-planned RCTs need to be conducted by standardizing the outcomes and outcome measurement methods.

Semiconductor Nanoparticle Anchored Single-Walled Carbon Nanotubes for a Bolometer.

The bolometer is developed using single-walled carbon nanotubes (SWCNT) anchored with semiconductor nanoparticles of cadmium sulfide, stannous disulfide, and zinc oxide (ZnO). The bolometric responses were recorded at varying temperatures from 10 K to room temperature. The anchored SWCNTs provided a higher temperature coefficient of resistance (TCR) than pristine SWCNTs. The largest TCR is recorded from SWCNTs/ZnO (-0.11%/K) at room temperature, which is 200% higher than pristine SWCNTs. The largest photoresponsivities of SWCNTs/ZnO under near-infrared (NIR) and wide wavelength source (200-1200 nm) illuminations are 5.06 and 37.51 mV/W, respectively. The extraordinary performance of SWCNTs/ZnO stands out at ∼17 × 104% under IR illumination. The study presents a significant advancement in the development of high-performance SWCNT bolometric materials by anchoring with semiconductor nanoparticles.

Assessment of Potentially Malignant Disorders among Men and Women in South Bihar Population.

Oral cancer is detected in 270,000 people per annum or around 3% of all malignancies. It ranks sixth among males and twelve among females in terms of prevalence. Mostly, all oral squamous cell carcinomas (OSCC) are responsible for 92-95% of cases. Oral carcinoma starts five years before the average age of PMD patients, who range in age from 5th to 6th decade of life. Thus, the goal of this study is to identify any relevant risk factors and assess the incidence of oral possibly malignant disorders in both men and women living in rural Bhojpur District, Bihar. A cross-sectional study has been carried out at the Sadar Hospital in Bhojpur by surveying volunteers at various oral health screening and treatment camps held from January 2022 to July 2022. A pre-validated questionnaire adapted and modified from Kumar S et al. was utilized to collect data in a qualitative interview. It was discovered that (17%) of all people had an oral possibly malignant disease. OSMF was the lesion with the greatest prevalence (7%) and lichen planus having the smallest prevalence (1%). Malignancy frequently develops from oral potential malignant diseases. Diabetes and BMI were inversely related, which is expected provided the socioeconomic position.

Dermatoglyphic Pattern Assessment in Smokeless Tobacco Users in the North Gujarat Population: A Comparative Case-Control Study.

Introduction: Dermatoglyphic patterns identify genetic conditions as they develop early in pregnancy and remain constant throughout life. Multiple studies suggest that there is a genetic link to smokeless tobacco use. So, this study has been conducted to assess dermatoglyphic patterns among smokeless tobacco users in the North Gujarat population with nonconsumers. Materials and Methods: A total of 500 cases were investigated for "ATD" angle and patterns, of which 250 subjects of smokeless tobacco are assessed for statistical significance via comparing them to 250 subjects of nonconsumers. Student's t-test was employed for evaluating quantitative factors (also known as the "ATD" angle), and the Chi-square test was used to analyze qualitative variables (also known as fingerprint patterns). A P value of 0.05 or less was considered significant. Results: In this study, the angle "ATD" was found to be reduced in both the palms of males (P 0.001) and females (P 0.001) when compared to controls, which was statistically highly significant. In our study, we discovered that the number of whorls and arches is lower in male cases as compared to male controls, which is highly significant (P = 0.020 and P = 0.010). Male cases had a greater number of loops than male controls, which was statistically significantly greater (P 0.001). Conclusion: In this latest study, an association between smokeless tobacco users and palmar dermatoglyphics was identified. Though dermatoglyphics solely is unable to identify individuals who abuse alcohol and/or cigarette packs, the results of this research could serve to further develop diagnostic guidelines.

Relationship of skin complexion with gingival tissue color and hyperpigmentation. A multi-ethnic comparative study.

BACKGROUND AND OBJECTIVE: The most frequently seen intra-oral soft tissue is the gingiva. Most often, it is seen as coral-pink tissue that surrounds the neck of the teeth. Gingiva that encircles the tooth necks and covers the alveolar processes of the jaws is an intra-oral tissue that exhibits biomimetic features. The wide range of colors of the gingiva depends on the configuration of gingival vascularity, the degree of epithelial cornification, level of melanogenesis, and the depth of epithelialization. However, the color of the gingiva varies depending on the degree of melanin pigmentation. The current study aimed to identify the different distribution patterns of gingival color and determine the correlation between skin color, gender, and geographical area of origin. MATERIALS AND METHODS: A total of 839 subjects were involved in the study where the gingival color and skin tone were measured using the Dummett-Gupta Oral pigmentation Index (DOPI) combined with VITA VMK MASTER and skin shade method developed by Revlon (USA) and L'Oreal (France) for makeup foundation shades. One investigator was calibrated for the examination of the colors after being tested for normal color vision and color aptitude using the line test. RESULTS: A significant association was found between skin color and gingival pigmentation (χ2 value (6) = 114.48; P = 0.001). It was also found that females (67.1%) significantly had darker gingiva than males (58.3%). The study statistics display that location of the individual was also statistically associated with melanin pigmentation of the gingiva (χ2 value (57) = 559.33; P = 0.001). CONCLUSION: The study concluded that gender, skin color, and individual location are significantly associated with gingival melanin pigmentation.

Exploring Climate Change Adaptation Practices and Agricultural Livelihoods among Rice Farmers of the Brahmaputra Valley in Northeast India.

Global climate change has seriously threatened agriculture and connected sectors, especially in developing countries like India. The Brahmaputra Valley in Assam, Northeast India, is vulnerable to climate change due to its agrarian economy, fragile geo-ecological setting, recurrent floods and droughts, and poor socioeconomic conditions of the farmers. The climate-induced hindrances faced by the rice farming community of this region and the local adaptation practices they employ have not been adequately studied. Therefore, we carried out a survey among 635 rice farmers across four agro-climatic zones of Assam, namely the Upper Brahmaputra Valley Zone, North Bank Plain Zone, Central Brahmaputra Valley Zone, and Lower Brahmaputra Valley Zone, to understand how they perceive and respond to climatic changes. The survey revealed that all the respondents have perceived an increase in ambient temperature, and 65% of the respondents have perceived a slight change in rainfall characteristics over the years. Most farmers reported adjusting the existing farming practices and livelihood choices to adapt to the changing climate. Farming adjustments were made mainly in terms of field preparation and management of water, rice variety, nutrients, and pests. Environmental variables like rainfall, flood, drought, and pest level, and socioeconomic variables like family size, education, farming experience, training, digital media exposure, and land area were found to influence farmers' adaptation choices. The findings imply that policies to strengthen flood, drought, pest management, education, land-use planning, agricultural training, and digital media applications in agriculture are needed for effective climate change adaptation in this region.

Enhancing the efficacy of depression detection system using optimal feature selection from EHR.

Diagnosing depression at an early stage is crucial and majorly depends on the clinician's skill. The present work aims to develop an automated tool for assisting the diagnostic procedure of depression using multiple machine-learning techniques. The dataset of sample size 4184 used in this study contains biometric and demographic information of individuals with or without depression, accessed from the University of Nice Sophia-Antipolis. The Artificial Neural Network (ANN), Support Vector Machine (SVM), Random Forest (RF) and Extreme Gradient Boosting (XGBoost) are used for classifying the depressed from the control group. To enhance the computational efficiency, various feature selection algorithms like Recursive Feature Elimination (RFE), Mutual Information (MI) and three bio-inspired techniques, viz. Particle Swarm Optimization (PSO), Genetic Algorithm (GA) and Firefly Algorithms (FA) have been incorporated. To enhance the feature selection process further, majority voting is carried out in all possible combinations of three, four and five feature selection techniques. These feature selection techniques bring down the feature set size significantly to a mean of 33 from the actual size of 61 which is a reduction of 45.90%. The classification accuracy of the enhanced model varies between 84.18% and 88.46%, which is a significant improvement in performance as compared to the pre-existing models (83.76-85.89%). The proposed predictive models outperform the pre-existing classification models without feature selection and thereby enhancing both the performance and efficiency of the diagnostic process.

Comparative Study of the Management of Distal Tibia Fractures by Nailing Versus Plating.

Introduction The purpose of this study was to evaluate the management of distal tibial fractures treated by interlocking nail and plate osteosynthesis and to assess their functional outcome according to the American Orthopaedic Foot and Ankle Society (AOFAS) score and complications. Methods Twenty patients were operated on in each group, i.e., intramedullary nailing (IMN) and plating (minimally invasive plate osteosynthesis, MIPO). The patients were regularly followed up at six weeks, 12 weeks, six months, and one year and evaluated clinically and radiologically with respect to operating time, union time, and functional outcome on the basis of AOFAS score and complications. Results The mean union time for the IMN group was 18.45±2.45 weeks and for the MIPO group was 20±3.21 weeks (p-value >0.05). The mean AOFAS score in the MIPO group was 91.2±6.81 and in the IMN group was 92.6±5.41 (p-value >0.05). Lesser complications in terms of implant irritation, ankle stiffness, and infection were observed in the IMN group than in the MIPO group (p-value <0.05). Conclusion Both the IMN and MIPO groups had satisfactory outcomes for treating distal tibial fractures, with a higher risk of wound complications in the MIPO group.

Trends in age of tobacco use initiation over time in Bangladesh, India and Pakistan: analysis of cross-sectional nationally representative surveys.

OBJECTIVE: Tobacco use begins at an early age and typically leads to a long-term addiction. The age of initiation for tobacco use is not well studied in South Asia, where 22% of tobacco smokers and 81% of smokeless tobacco (SLT) users reside. METHODS: Data from the nationally representative Global Adult Tobacco Surveys in India, Bangladesh and Pakistan were analysed to examine patterns of initiation among smokers and smokeless tobacco users. RESULTS: Data on 94 651 individuals were analysed, of which 13 396 reported were ever daily smokers and 17 684 were ever SLT users. The proportion of individuals initiating tobacco use before the age of 15 years has increased over time. The rates of SLT initiation among those aged 15-24 years increased markedly in Bangladesh (by 7.8%) and Pakistan (by 37.7%) between 1983 and 1999-2000. Among males, the increase in SLT initiation was higher in individuals aged below 15 years compared with other age groups in India and Bangladesh. Smoking initiation among females aged below 15 years has also significantly increased in India over time. Compared with the initiation of tobacco smoking before the age of 15 years, a greater increase in the proportion of SLT users was observed in urban areas. CONCLUSION: Our findings indicate that the proportion of youth initiating tobacco (both smoking and smokeless) before the age of 15 years has increased over time in all three countries. Moreover, variations in age at initiation for different types of tobacco products across countries, and by rurality, were noticeable. Younger youths (aged up to 15 years) should therefore be a priority population for tobacco control interventions. Strategies such as raising the legal age of tobacco sale and use to 21 years, and, other measures under WHO Framework Convention on Tobacco Control (FCTC), may prevent underage use and avert lifelong addiction to tobacco products.

Bibliometric analysis, physical properties, and experimental evaluation of additives-diesel ternary blends.

The availability of petroleum fuels is being challenged due to high demand and heavy dependence on imports, raising awareness of the need for cleaner alternatives. Urbanization, air quality, economic factors, and emissions limits motivate the search for alternative fuels compatible with compression ignition engines. A comprehensive bibliometric analysis further underscores the escalating worldwide research efforts in this critical domain. According to the existing literature, nitromethane and 2-ethoxy ethyl acetate have demonstrated superior physical and combustion properties compared to other additives. To explore their potential, a meticulous performance and emission analysis was conducted using a single-cylinder, 4-stroke VCR CI engine, employing varying proportions of 2-ethoxy ethyl acetate and a constant 2% blend of nitromethane, with EEA concentrations ranging from 5, 10, to 15% (v/v). This research delved into the influence of these diverse fuel blends on the performance of CI engines and exhaust characteristics within a compression ratio spectrum spanning from 17 to 20. The experimental findings revealed that ternary blends, although having a marginal impact on engine performance, exhibited lower emissions compared to pure diesel. The pinnacle of this investigation emerged with the EEA5NM2D93 blend, which yielded optimal results in terms of both performance and emission characteristics.

Outcomes and Challenges in the Programmatic Implementation of Tuberculosis Preventive Therapy among Household Contacts of Pulmonary TB Patients: A Mixed-Methods Study from a Rural District of Karnataka, India.

The National TB Elimination Programme (NTEP) of India is implementing tuberculosis preventive treatment (TPT) for all household contacts (HHCs) of pulmonary tuberculosis patients (index patients) aged <5 years and those HHCs aged >5 years with TB infection (TBI). We conducted an explanatory mixed-methods study among index patients registered in the Kolar district, Karnataka during April-December 2022, to assess the TPT cascade and explore the early implementation challenges for TPT provision. Of the 301 index patients, contact tracing home visits were made in 247 (82.1%) instances; a major challenge was index patients' resistance to home visits fearing stigma, especially among those receiving care from the private sector. Of the 838 HHCs, 765 (91.3%) were screened for TB; the challenges included a lack of clarity on HHC definition and the non-availability of HHCs during house visits. Only 400 (57.8%) of the 692 eligible HHCs underwent an IGRA test for TBI; the challenges included a shortage of IGRA testing logistics and the perceived low risk among HHCs. As HHCs were unaware of their IGRA results, a number of HHCs actually eligible for TPT could not be determined. Among the 83 HHCs advised of the TPT, 81 (98%) initiated treatment, of whom 63 (77%) completed treatment. Though TPT initiation and completion rates are appreciable, the NTEP needs to urgently address the challenges in contact identification and IGRA testing.

Effectiveness of the WHO Protocol for the Management of Shock in Children With Severe Acute Malnutrition.

Background The WHO protocol for the management of shock in children with severe acute malnutrition (SAM) is not supported by physiological evidence. In this study, we aimed to assess the effectiveness of the WHO treatment protocol in the management of shock in children with SAM. Methodology This cohort study included children aged 2-60 months with WHO-defined SAM and fulfilling the WHO criteria for identification of shock. The exclusion criteria included severe anemia (hemoglobin <4 g/dL), congenital anomalies, congenital heart defects, and chronic diseases. The WHO treatment protocol for the management of shock was used, and features of resolution of shock were assessed at eight and 24 hours. Oliguria was recorded at eight and 24 hours along with in-hospital mortality. Multiple logistic regression was used to determine predictors of mortality. Results Of 53 children, 40 (75.4%) were discharged and 13 (24.5%) expired. We observed significant resolution of features of shock at 24 hours compared to eight hours (35 (71.4%) vs. 10 (18.8%), p < 0.0001). Further analysis revealed a significant resolution of features of shock (p = 0.03) at 24 hours in both fluid-responsive (24 vs. 10) and fluid-refractory children (11 vs. 27) compared to eight hours. Multivariate analysis revealed that mechanical ventilation was positively related to death (odds ratio (OR) = 85, 95% confidence interval (CI) = 8.49, 860, p < 0.0001), and inotrope scores <20 (OR = 0.053, 95% CI = 0.004, 0.64, p = 0.021) and blood transfusion (OR = 0.025, 95% CI = 0.001, 0.61, p = 0.024) had favorable outcomes. Conclusions The WHO protocol for the management of shock in children with SAM is effective in fluid-responsive shock whereas evidence was inconclusive in fluid-refractory shock.

Impact of Portraiture Photography on Orthodontic Treatment: A Systematic Review and Meta-Analysis.

Due to the clear depiction of facial aesthetics and other craniofacial parameters, portraiture photography (PP) is becoming more and more necessary in modern clinical practice. The studies chosen for this review's inclusion looked at how PP affected the orthodontic treatment and diagnostic procedure on the subjects who were watched in the studies. Studies published within the last decade precisely from 2013 were searched for across major online databases after devising a proper search strategy. Multiple reviewers created a specific data extraction form that was used for the investigation, followed by the evaluation of bias and the variables found in each of the chosen papers. This form was meant for the assessment for various variables encountered in this study. According to the meta-analysis, using PP was related with a statistically significant decrease in the risk of orthodontic treatment and diagnostic modalities, with odds ratios (OR) of 0.52 with a 95% confidence interval (CI) of (0.28, 0.96), and a relative risk (RR) of 0.66 with a CI of (0.45, 0.96). In orthodontics, PP is an important tool that offers useful data for diagnosis, treatment planning, and tracking treatment success. To validate the results of studies like ours, a sizable evidence sample is required due to the limited number of trials that have been performed in this area.

Comparative evaluation of antimicrobial efficacy of different combinations of calcium hydroxide against Enterococcus faecalis.

BACKGROUND: The study aims to compare the synergistic antibacterial efficacy of different combinations of calcium hydroxide as an intracanal medicament against E. faecalis. MATERIAL AND METHODS: The current study included four hundred extracted human permanent mandibular premolar teeth. After complete chemo-mechanical preparation, the middle third of the root was sectioned using a rotary diamond disc and a total of 400 samples were obtained. The specimens were inoculated with E. faecalis for 21 days. After that, specimens were divided into five groups (n = 80) based on materials used for the disinfection of samples: Group I, calcium hydroxide alone; Group II, calcium hydroxide + 2% chlorhexidine gel; Group III, calcium hydroxide + 2% chitosan gel; Group IV, calcium hydroxide + 0.02% silver nanoparticle gel; Group V, calcium hydroxide + Bioactive glass S53P4. Dentin shavings from the apical third were obtained from the inner third of dentin were obtained using gates glidden no.1 to the apical depth, followed by no.2, 3, 4 and 5 analyzed for E. faecalis using the culture method. One-way analysis of variance (ANOVA) was used for data analysis, followed by post-hoc Tukey's test for multiple comparisons of means to check the difference in bacterial inhibition between the groups. RESULTS: ANOVA results revealed a significant reduction of bacterial counts in all the groups compared (p < 0.001). Intergroup comparison showed maximum bacterial reduction (p < 0.001) with calcium hydroxide + bioactive glass S53P4 compared with other groups. CONCLUSION: Synergistic effect of calcium hydroxide showed better bacterial reduction compared to calcium hydroxide alone. Among the combinations evaluated, calcium hydroxide with bioactive glass, found to be most effective compared to other groups.
