Complete Correction following Temporary Hemiepiphysiodesis using 2-hole Reconstruction Plates among Skeletally Immature Patients with Angular Deformities around Knees: A Descriptive Cross-sectional Study.

INTRODUCTION: Studies have shown that 2-hole reconstruction plates can be used effectively as tension band plates for temporary hemiepiphysiodesis. However, limited data is available regarding the effectiveness of such plates in terms of complete correction rates. This study was aimed to find out the prevalence of complete correction following temporary hemiepiphysiodesis using 2-hole reconstruction plates among skeletally immature patients with angular deformities around knees. METHODS: A descriptive cross-sectional study was carried out among skeletally immature patients with angular deformities around knees undergoing temporary hemiepiphysiodesis after getting approval from the Institutional Review Committee (Reference number: B&BIRC-23-05). The data were collected between 1 January 2012 to 31 December 2018. All skeletally immature patients with angular deformities around knees undergoing temporary hemiepiphysiodesis using 2-hole reconstruction plates were included. Patients who required additional procedures or implants for deformity correction and those who did not provide consent were excluded. Convenience sampling method was used. Point estimate at 95% Confidence Interval was calculated. RESULTS: Among 102 patients, 66 (64.70%) patients achieved complete correction (59.97-69.43 at 95% Confidence Interval). Mean age of the patients was 8.21±3.11 years and 43 (65.15%) were males and 23 (34.84%) were females. CONCLUSIONS: The prevalence of complete correction following temporary hemiepiphysiodesis using 2-hole reconstruction plate among skeletally immature patients with angular deformities around knees was lower than that reported in other international studies.

Plant growth-promoting rhizobacterial secondary metabolites in augmenting heavy metal(loid) phytoremediation: An integrated green in situ ecorestorative technology.

In recent times, increased geogenic and human-centric activities have caused significant heavy metal(loid) (HM) contamination of soil, adversely impacting environmental, plant, and human health. Phytoremediation is an evolving, cost-effective, environment-friendly, in situ technology that employs indigenous/exotic plant species as natural purifiers to remove toxic HM(s) from deteriorated ambient soil. Interestingly, the plant's rhizomicrobiome is pivotal in promoting overall plant nutrition, health, and phytoremediation. Certain secondary metabolites produced by plant growth-promoting rhizobacteria (PGPR) directly participate in HM bioremediation through chelation/mobilization/sequestration/bioadsorption/bioaccumulation, thus altering metal(loid) bioavailability for their uptake, accumulation, and translocation by plants. Moreover, the metallotolerance of the PGPR and the host plant is another critical factor for the successful phytoremediation of metal(loid)-polluted soil. Among the phytotechniques available for HM remediation, phytoextraction/phytoaccumulation (HM mobilization, uptake, and accumulation within the different plant tissues) and phytosequestration/phytostabilization (HM immobilization within the soil) have gained momentum in recent years. Natural metal(loid)-hyperaccumulating plants have the potential to assimilate increased levels of metal(loid)s, and several such species have already been identified as potential candidates for HM phytoremediation. Furthermore, the development of transgenic rhizobacterial and/or plant strains with enhanced environmental adaptability and metal(loid) uptake ability using genetic engineering might open new avenues in PGPR-assisted phytoremediation technologies. With the use of the Geographic Information System (GIS) for identifying metal(loid)-impacted lands and an appropriate combination of normal/transgenic (hyper)accumulator plant(s) and rhizobacterial inoculant(s), it is possible to develop efficient integrated phytobial remediation strategies in boosting the clean-up process over vast regions of HM-contaminated sites and eventually restore ecosystem health.

Characterization of Taro (Colocasia esculenta) stolon polysaccharide and evaluation of its potential as a tablet binder in the formulation of matrix tablet.

This investigation focuses on the extraction, characterization, and evaluation of taro (Colocasia esculenta) stolon polysaccharide (TSP) as a tablet binding agent, which is obtained from edible taro stolon. TSP was subjected to phytochemical screening and characterized by FTIR, DSC, TGA, DTA, XRD, particle size, polydispersity index, zeta potential, rheological behavior, and SEM. The tablets prepared with varying concentrations of TSP (2.5 %, 5 %, 7.5 %, and 10 % w/w) and diclofenac sodium (DS) were evaluated and compared with the same concentrations of gum acacia and PVP K-30. The presence of carbohydrates was confirmed by Molisch's test. The FTIR spectra established the compatibility of the drug with excipients. The SEM images revealed asymmetric and elongated particles of TSP powder. The hydration kinetics study showed matrix hydration and water penetration velocity within the range of 0.602-0.753 g/g and 0.112-0.189 cm/g.h, respectively. The tablets showed drug release of >75 % at 45 min. The release-exponent value above 0.89 indicated a super case II drug transport combining matrix erosion and diffusion. Optimum tablet hardness and very low friability, even at 2.5 % binder concentration, suggested the potential application of the novel TSP as a tablet binder in the formulation of the tablets.

Mpox virus infection in women and outbreak sex disparities: A Systematic Review and Meta-analysis.

BACKGROUND: Although the recent literature indicates that mpox (monkeypox) primarily affects men, there are also multiple reports in women. Estimates of the sex distribution of mpox patients and patterns will enable a better understanding of the ongoing mpox outbreak. METHODS: In this systematic review and meta-analysis, seven databases were searched for studies published in English up to January 4th, 2023. The proportion of women with mpox was the primary outcome. A random-effects model was fitted for the primary outcome, and a sensitivity analysis was performed to check possible outliers in the studies. RESULTS: Here we screened 470 articles and included 60 studies for qualitative synthesis. 42 studies with 3125 women out of 47,407 confirmed cases were found suitable for meta-analysis. The pooled proportion of female patients is 17.22% (95% CI: 10.49-25.11; I2 = 98.86%). Subgroup analyses reveal higher proportion before 2022 [44.09% (42.93-46.86] than 2022 onwards [2.40% (1.17-3.98)], and in endemic countries [43.13% (37.63-48.72)] than in nonendemic countries [6.15% (2.20-11.65)]. CONCLUSIONS: There is considerable caseload (17.22%) amongst women, which must be seen in the context of a much higher proportion (44.09%) in studies prior to 2022 compared to 2.40% in the 2022 outbreak indicating an epidemiological shift. Data on disease characteristics among women with mpox disease are scarce. Further studies should focus on these aspects to better understand the disease in women and empower epidemiologists and clinicians to make evidence-based decisions for this vulnerable group.

Mpox (formerly known as monkeypox) is an infection caused by the monkeypox virus. While it is known to affect men more commonly than women, there are also reports of this infection in women. We have searched the literature to find out how frequently mpox affected women. We found that 17% of mpox patients were female. However, this number was 44% before 2022, and has reduced to 2% from 2022 onwards. This indicates changes in mpox disease characteristics and in the ability to infect different sexes. Further studies are needed to better understand the disease in women and empower epidemiologists and clinicians to make evidence-based decisions for this group.

Clinical Evaluation of Role of Laser in Soft Tissue Surgical Guide for Implant Placement.

Background: Applying automated laser ablation procedures with pulsed, electronically administered diode laser equipment, and large-area masking results in highly aligned, uniform microstructures on these surfaces. Aim: Clinical evaluation of role of laser in soft tissue surgical guide for implant placement. Methods and Materials: This study included 30 patients with dental implants in their oral cavity. These patients were divided into two categories. Category 1: Control where laser was not used for soft tissue guide. Category 2: Laser group where laser was used for soft tissue guide. There was the evaluation of bleeding index, plaque index, probing depth, and crestal bone loss in each patient at 3-month follow-up, 6-month follow-up, and 12-month follow-up by the same clinician. Results: There was decline in values of bleeding index, plaque index, and probing depth in both control group and laser group at 3-month follow-up, 6-month follow-up, and 12-month follow-up. However, the decline in values was more pronounced in laser group. There was more increase in crestal bone loss as time progressed in control group while the increase in crestal bone loss in laser group was minimal as time progressed. Conclusion: Laser can be applied successfully in soft tissue surgical guide for implant placement as it gives better results regarding soft tissue health and crestal bone loss.

Sulforaphane regulates cell proliferation and induces apoptotic cell death mediated by ROS-cell cycle arrest in pancreatic cancer cells.

Background: Pancreatic cancer (PC), sometimes referred to as pancreatic ductal adenocarcinoma (PDAC), is a major cause of global mortality from cancer. Pancreatic cancer is a very aggressive and devastating kind of cancer, characterized by limited options for therapy and low possibilities of survival. Sulforaphane (SFN), a naturally occurring sulfur-containing compound, is believed to possess anti-inflammatory, anti-obesity, and anti-cancer characteristics. Objective: However, efficient preventative and treatment measures are essential and SFN has been studied for its ability to suppress pancreatic cancer cell proliferation and induce apoptosis. Methods: Here, SFN induced cytotoxicity and apoptosis in PDAC cell lines such as MIA PaCa-2 and PANC-1 cells, as evaluated by cytotoxicity, colony formation, western blot analysis, fluorescence-activated cell sorting (FACS), reactive oxygen species (ROS) detection, caspase-3 activity assay, immunofluorescence assay, and mitochondrial membrane potential assay. Results: In MIA PaCa-2 and PANC-1 cells, SFN inhibited cell survival and proliferation in a dose-dependent manner. The activation of caspase zymogens results in cleaved PARP and cleaved caspase-3, which is associated with an accumulation in the sub G1 phase. Furthermore, SFN increased ROS level and γH2A.X expression while decreasing mitochondrial membrane potential (ΔΨm). Notably, the ROS scavenger N-Acetyl-L-cysteine (NAC) was shown to reverse SFN-induced cytotoxicity and ROS level. Subsequently, SFN-induced cell cycle arrest and apoptosis induction as a Trojan horse to eliminate pancreatic cancer cells via ROS-mediated pathways were used to inhibit pancreatic cancer cells. Conclusion: Collectively, our data demonstrates that SFN-induced cell death follows the apoptosis pathway, making it a viable target for therapeutic interventions against pancreatic cancer.

Clinical and Functional Outcomes of Platelet-Rich Plasma Injection and Corticosteroid Injection in Patients With De Quervain's Tenosynovitis: A Comparative Retrospective Study.

Background and aim De Quervain's tenosynovitis (DQST) is a prevalent condition involving tendon inflammation in the wrist. This study compares the clinical and functional outcomes between patients receiving platelet-rich plasma (PRP) injections and those receiving corticosteroid injections for DQST. Methods A retrospective study conducted at Sri Devaraj Urs Academy of Higher Education and Research, Kolar, India, included 58 patients with DQST, divided into Group A (PRP injection) and Group B (corticosteroid injection). Assessments were conducted using the Visual Analogue Scale (VAS), the Disabilities of the Arm, Shoulder, and Hand (DASH) score, and the Modified Mayo Wrist Score (MMWS) at baseline, one month, three months, and six months. Statistical analyses were performed using IBM SPSS Statistics for Windows, Version 22.0 (Released 2013; IBM Corp., Armonk, NY, USA), with significance set at p < 0.05. Results Both treatment groups demonstrated a reduction in VAS scores over time. Significant improvements were observed at one month (p = 0.007) and six months (p = 0.004) post-injection. Baseline (p = 0.336) and three-month (p = 0.829) VAS scores showed no significant differences. Similarly, DASH scores were not significantly different at any measured time points: baseline (p = 0.331), one month (p = 0.592), three months (p = 0.707), and six months (p = 0.314). MMWS scores also showed no significant differences at baseline (p = 0.123), one month (p = 0.101), three months (p = 0.422), and six months (p = 0.956). Independent sample t-tests highlighted significant VAS score improvements at one month (t = 2.813, p = 0.007) and six months (t = -3.009, p = 0.004), but DASH and MMWS scores showed no significant differences at any time points. Chi-square tests indicated no significant associations between the groups at one-month, three-month, and six-month follow-ups. Conclusion Both PRP and corticosteroid injections effectively alleviate pain in DQST patients, as evidenced by significant VAS score improvements. However, functional outcomes measured by DASH and MMWS scores did not significantly differ between the treatments. These results suggest that while both treatments are effective for pain management, their short-term impact on functional improvement may be similar. To investigate long-term functional results, more research with bigger sample sizes and longer follow-up periods is required.

Novel 3-dimensional classification of cervical abrasion using CBCT: A comprehensive analysis.

Introduction: Tooth cervical abrasion (CA) is a prevalent non-carious cervical lesion that poses challenges for accurate diagnosis from periapical radiographs due to difficulties in assessing the lesion's extent, associated bone loss, and pulpal involvement. The presence of overlying bone structures on the palatal side when lesions are located on the buccal side, or vice versa, further complicates radiographic interpretation. So it is important to define the lesions in all three dimensions. Objective: To provide a three-dimensional descriptive classification for cervical abrasion lesions using Cone Beam Computed Tomography (CBCT). Method: A total of 50 patients with cervical abrasion were selected for the study. From these patients, teeth (n = 10) from each of the four different quadrants were chosen. A CBCT scan with a 6 × 6 cm field of view (FOV) was performed, and the DICOM files of the cervical lesions were transferred to 3-D imaging software. The CBCT images of the cervical abrasion lesions were assessed at the level of the deepest point of the lesion along the long axis of the tooth in both axial and sagittal planes. The height (A), buccolingual dimension (B), circumferential spread (C), and remaining dentine thickness (D) were evaluated and classified using new scoring criteria for each dimension. The reliability and reproducibility of the classification were assessed to ensure its clinical applicability. Conclusion: CBCT can be utilized to classify tooth cervical abrasion in endodontics, enhancing diagnosis, analysis, and treatment outcomes. This three-dimensional view facilitates easier communication among clinicians, allows for tailored treatment approaches, and opens new avenues for research.

Ultrasmall CsPbBr3 Nanocrystals as a Recyclable Heterogeneous Photocatalyst in 100% E- and Anti-Markovnikov Sulfinylsulfonation of Terminal Alkynes.

The precise synthesis of ultrasmall, monodisperse CsPbBr3 nanocrystals is crucial due to their enhanced photophysical properties resulting from strong quantum confinement effects. Traditional methods struggle with size control, complicating synthesis. Although CsPbBr3 nanocrystals find applications in LEDs and photovoltaics, their use in photocatalysis for organic reactions remains limited. Our study introduces ultrasmall TBIA-CsPbBr3 nanocrystals (∼5.6 nm), synthesized via a three-precursor hot injection method using tribromoisocyanuric acid (TBIA) as a bromine precursor for the first time. These nanocrystals exhibit a near-unity photoluminescence quantum yield (PLQY) of 0.99 and an elevated oxidation potential of +1.80 V. We demonstrate their efficacy as recyclable heterogeneous photocatalysts in a one-pot, 100% E-selective, anti-Markovnikov sulfinylsulfonation of terminal alkynes under visible light, achieving a high product conversion rate (PCR) of 62,500 µmol g-1 h-1 and recyclability for up to five cycles. Density functional theory (DFT) calculations support the exclusive formation of the E-isomer. TBIA-CsPbBr3 outperforms other CsPbBr3 perovskites in photocatalysis, with superior efficiency attributed to their extended excited-state lifetime and higher surface area, which accelerates the organic transformation process.

N-Halosuccinimide-CeCl3 Transient Charge-Transfer Complexes as Semi Heterogeneous Photocatalyst in Cyclization of N-Propargylamides.

In this work, we used photoinert anhydrous cerium(III) chloride, to form a transient charge-transfer (CT) complex with NXS (N-bromosuccinimide or NBS and N-iodosuccinimide or NIS) in acetonitrile. These transient CT complexes acted as a semi-heterogeneous photocatalyst. These complexes allowed the Ce(III) ions to absorb light, turning them into strong electron donors that transferred electrons to NXS. This created halide radicals from NXS radical anions, helping to turn N-propargylamides into oxazole aldehydes. Experiments with DMPO and spin-trapping showed that a radical-based mechanism followed a single electron transfer (SET) pathway. Notably, CeCl3 was reused after the reaction without much decomposition, as it was regenerated and separated through simple filtration.

A Cross-Sectional Study of Cardiovascular Autonomic Reactivity in Ehlers-Danlos Syndrome.

BACKGROUND: Ehlers-Danlos syndrome (EDS) may be linked to dysfunction in the autonomic nervous system, affecting collagen production and processing. These collagen abnormalities lead to a condition called dysautonomia. Findings underscore the need for further investigation into autonomic nervous system function in EDS which involves larger studies to strengthen the evidence of non-invasive screening tools like cardiovascular reflex tests. These tests might offer a valuable way to assess an individual's risk for future complications. OBJECTIVE: This study aimed to assess autonomic reactivity in EDS patients using cardiovascular reflex tests. METHODS: This study was conducted at the Department of Physiology, Naraina Medical College and Research Centre, Kanpur (Uttar Pradesh). The cardiovascular reflex test was used to identify 60 individuals, 30 of whom were EDS patients and 30 were healthy controls, with a common age limit of 18-25 years. Cardiovascular reflex tests, such as the delta heart rate, lying-to-standing test (LST), deep breathing test (DBT), and Valsalva maneuver, were performed and recorded for each subject. IBM SPSS Statistics for Windows, Version 21.0 (Released 2012; IBM Corp., Armonk, New York, United States) was used for the compilation and analysis of data. RESULTS: The expiration-to-inspiration (E:I) ratio and delta heart rate of the EDS patients both significantly decreased as compared to the healthy control group (1.10±0.02 versus 1.22±0.77 and 14.03±0.31 versus 15.52±0.32). The Valsalva ratio of the EDS patients decreased (1.28±0.01) as compared to the healthy control group (1.46±0.01), which was statistically significant. The 30:15 ratio in the EDS patients was significantly decreased compared to the healthy control group (1.08±0.01 versus 1.15±0.01). The handgrip test and cold pressor test results were statistically insignificant. CONCLUSION: The study suggests a connection between EDS and autonomic nervous system dysfunction, causing symptoms like tachycardia and hypotension. It recommends exploring non-invasive cardiovascular reflex tests as a tool to identify autonomic dysfunction in EDS patients and predict long-term cardiovascular complications. These tests offer valuable insights into autonomic function.

The sulfonamide Schiff base (C16H14N4O3S) was successfully synthesized and experimentally ascertained. The main purpose of this research is to investigate the geometry of the aforesaid molecule using both experimental and density functional theory (DFT) techniques and determine its drug likeness characteristics, docking ability as an insulysin inhibitor, and its NLO property. For the computational investigations the DFT approaches were utilized at the B3LYP level with the 6-311G+(d,p) basic set. The experimental results of the compound (such as FT-IR, UV-Vis, and 1H NMR) were compared with simulated data. The both results were well and consistent with previously related published data. The obtained spectral results confirm the formation of the Schiff base compound. Both π-π* and n-π* interactions were found in experimental and computational UV-Vis spectra, as well as in the natural bond orbital (NBO) study. The molecular, electronic, covalent, and non-covalent interactions were analyzed using DFT studies. Both experimental and simulation results revealed that the compound is successfully formed and relatively stable. The compound with a lower band gap showed high chemical reactivity. The medicinal characteristics of the compound were evaluated using in silico medicinal methods. The investigated compound was also followed Pfizer, Golden Triangle, GSK as well as Lipinski's rules. Therefore, the compound has more favorable absorption, distribution, metabolism, excretion, and toxicity (ADMET) profile and it can be used as non-toxic oral drug candidate. The compound was exhibited good insulysin inhibitory activity and it has almost eighteen times higher non-linear optical properties than urea and three times higher than potassium dihydrogen phosphate (KDP).

Non-vascularised fibula as an adjuvant in the management of diaphyseal humerus non-union- A meta-analysis and systematic review.

Introduction: There is no standard protocol for managing non-union of diaphyseal humerus bone, with several authors reporting their results using various techniques and methods for its management. No meta-analysis has reported the results of managing these cases with non-vascularized fibula grafting as an adjuvant for osteosynthesis. Materials and methods: This meta-analysis was performed to estimate the pooled data for calculating the union rates in diaphyseal humerus fractures managed with non-vascularized fibula grafting. Risk of Bias was computed using the Joanna Briggs Institute appraisal tool. Results: A total of 5 studies, comprising 102 patients, were included. The pooled estimate demonstrated that 94 patients achieved bone union with intramedullary fibular strut grafting. The pooled union rate (per 100 events) was 90.59 (95 % CI, 82.86-95.04, I2 = 0). The present meta-analysis also showed a significant improvement in DASH scores following the use of a non-vascularized fibula graft with a common effects model (SMD = 4.08; 95%CI: 3.44; 4.72; p < 0.01 I2 = 19 %, p-value for Q test = 0.29). Conclusion: Non-vascularized fibula grafting is an excellent adjuvant for the internal fixation of non-union diaphyseal humerus fractures. Although there is limited literature, further studies should highlight and assess the treatment of these uncommon but disabling conditions.

Are case reports valuable? Exploring their role in evidence based medicine and patient care.

They provide unique insights into rare conditions, novel treatments, and adverse effects, serving as valuable educational tools and generating new hypothesis. Despite their limitations in generalizability, case reports contribute significantly to evidence-based practice by offering detailed clinical information and fostering critical thinking among healthcare professionals. By acknowledging their limitations and adhering to reporting guidelines, case reports can contribute significantly to medical knowledge and patient care within the evolving landscape of EBM. This editorial explores the intrinsic value of case reports in EBM and patient care.

Infrared signature of the hydroperoxyalkyl intermediate (·QOOH) in cyclohexane oxidation: An isomer-resolved spectroscopic study.

Infrared (IR) action spectroscopy is utilized to characterize carbon-centered hydroperoxy-cyclohexyl radicals (·QOOH) transiently formed in cyclohexane oxidation. The oxidation pathway leads to three nearly degenerate ·QOOH isomers, ß-, γ-, and δ-QOOH, which are generated in the laboratory by H-atom abstraction from the corresponding ring sites of the cyclohexyl hydroperoxide (CHHP) precursor. The IR spectral features of jet-cooled and stabilized ·QOOH radicals are observed from 3590 to 7010 cm-1 (∼10-20 kcal mol-1) at energies in the vicinity of the transition state (TS) barrier leading to OH radicals that are detected by ultraviolet laser-induced fluorescence. The experimental approach affords selective detection of ß-QOOH, arising from its significantly lower TS barrier to OH products compared to γ and δ isomers, which results in rapid unimolecular decay and near unity branching to OH products. The observed IR spectrum of ß-QOOH includes fundamental and overtone OH stretch transitions, overtone CH stretch transitions, and combination bands involving OH or CH stretch with lower frequency modes. The assignment of ß-QOOH spectral features is guided by anharmonic frequencies and intensities computed using second-order vibrational perturbation theory. The overtone OH stretch (2νOH) of ß-QOOH is shifted only a few wavenumbers from that observed for the CHHP precursor, yet they are readily distinguished by their prompt vs slow dissociation rates to OH products.

Synthesis, quantum chemical calculations, in silico and in vitro bioactivity of a sulfonamide-Schiff base derivative.

The sulfonamide Schiff base compound (E)-4-((4-(dimethylamino)benzylidene)amino)-N-(5-methylisoxazol-3-yl)benzenesulfonamide was successfully prepared and fully characterized. The foremost objective of this study was to explore the molecular geometry of the aforementioned compound and determine its drug likeness characteristics, docking ability as an insulysin inhibitor, anticancer and antioxidant activities. The molecular structure of this compound was optimized using the B3LYP/6-311G+(d,p) level of theory. The compound was completely characterized utilizing both experimental and DFT approaches. Molecular electrostatic potential, frontier molecular orbitals, Fukui function, drug likeness, and in silico molecular docking analyses of this compound were performed. Wave functional properties such as localized orbital locator, electron localization function and non-covalent interactions were also simulated. The compound was screened for anticancer and antioxidant activities using in vitro technique. The observed FT-IR, UV-Vis, and 1H NMR results compared with simulated data and both results were fairly consistent. The experimental and computational spectral findings confirm the formation of the Schiff base compound. Both π-π* and n-π* transitions were observed in both experimental and computational UV-Vis spectra. The examined compound followed to Pfizer, Golden Triangle, GSK, and Lipinski's rules. Consequently, it possesses a more favorable absorption, distribution, metabolism, excretion, and toxicity (ADMET) profile, making it a suitable candidate for non-toxic oral drug use. Moreover, the compound exhibited promising insulysin inhibition activity in an in silico molecular docking. The compound showed in vitro anticancer activity against A549 cancer cells with an IC50 value of 40.89 µg/mL and moderate antioxidant activity.

Ethical considerations during Mpox Outbreak: a scoping review.

BACKGROUND: Historically, epidemics have been accompanied by the concurrent emergence of stigma, prejudice, and xenophobia. This scoping review aimed to describe and map published research targeting ethical values concerning monkeypox (mpox). In addition, it aimed to understand the research gaps related to mpox associated stigma. METHODS: We comprehensively searched databases (PubMed Central, PubMed Medline, Scopus, Web of Science, Ovid, and Google Scholar) to identify published literature concerning mpox ethical issues and stigma from May 6, 2022, to February 15, 2023. The key search terms used were "monkeypox", "ethics", "morals", "social stigma", "privacy", "confidentiality", "secrecy", "privilege", "egoism", and "metaethics". This scoping review followed the framework proposed by Arksey and O'Malley in 2005 and was further improved by the recommendations of Levac et al. in 2010. RESULTS: The search strategies employed in the scoping review yielded a total of 454 articles. We analyzed the sources, types, and topics of the retrieved articles/studies. The authors were able to identify 32 studies that met inclusion criteria. Six of the 32 included studies were primary research. The study revealed that the ongoing mpox outbreak is contending with a notable surge in misinformation and societal stigma. It highlights the adverse impacts of stigma and ethical concerns associated with mpox, which can negatively affect people with the disease. CONCLUSION: The study's findings underscore the imperative need to enhance public awareness; involve civil society; and promote collaboration among policymakers, medical communities, and social media platforms. These collective endeavors are crucial for mitigating stigma, averting human-to-human transmission, tackling racism, and dispelling misconceptions associated with the outbreak.

Preparation, characterization and antioxidant and anticancerous potential of Quercetin loaded ß-glucan particles derived from mushroom and yeast.

ß-glucans are polysaccharides found in the cell walls of various fungi, bacteria and cereals. ß-glucan have been found to show various kinds of anti-inflammatory, antimicrobial, antidiabetic antioxidant and anticancerous activities. In the present study, we have isolated ß-glucan from the baker's yeast Saccharomyces cerevisiae and white button mushroom Agaricus bisporus and tested their antioxidant potential and anticancerous activity against prostate cancer cell line PC3. Particles were characterized with zeta sizer and further with FTIR that confirmed that the isolated particles are ß-glucan and alginate sealing made slow and sustained release of the Quercetin from the ß-glucan particles. Morphological analysis of the hollow and Quercetin loaded ß-glucan was performed with the SEM analysis and stability was analyzed with TGA and DSC analysis that showed the higher stability of the alginate sealed particles. Assessments of the antioxidant potential showed that Quercetin loaded particles were having higher antioxidant activity than hollow ß-glucan particles. Cell viability of the PC3 cells was examined with MTT assay and it was found that Quercetin loaded alginate sealed Agaricus bisporus derived ß-glucan particles were having lowest IC50. Further ROS generation was found to increase in a dose dependent manner. Apoptosis detection was carried out with Propidium iodide and AO/EtBr staining dye which showed significant death in the cells treated with higher concentration of the particles. Study showed that particles derived from both of the sources were having efficient anticancer activity and showing a dose dependent increase in cell death in PC3 cells upon treatment.

Factors Associated with High Prevalence of Multibacillary Leprosy in West Bengal: A Case-Control Study.

BACKGROUND: High proportion of multibacillary (MB) among newly diagnosed leprosy cases poses a public health challenge. OBJECTIVES: This study aimed to find out the factors associated with the high burden of MB leprosy in West Bengal. MATERIALS AND METHODS: This case-control study was conducted from August 2020 to December 2022 in three high-endemic districts (annual new case detection rate ≥10/lakh) of West Bengal. OBJECTIVES: MB cases registered under the National Leprosy Eradication Programme were considered as case and paucibacillary (PB) cases were considered as control. Weighted sample sizes for cases and controls in each of the three districts were selected using simple random sampling from the list of registered leprosy patients. Requisite data were collected through structured interview with a validated questionnaire in Bengali. R, version 4.1.1 (R Foundation for Statistical Computing, 2021, Vienna, Austria) was used for data analysis. A binary logistic regression model was prepared with the type of leprosy as a dependent variable. RESULTS: Three hundred and ninety-eight individuals, 204 MB and 194 PB, participated in this study with 1.97% nonresponse rate. Gender, marital status, and diagnostic delay (adjusted odds ratio = 2.75 [1.66,4.65]) were associated with developing MB. Not perceiving the symptoms seriously (90, 56% [PB], 97, 51% [MB]), lack of knowledge about the disease and its complications (47, 29% [PB], 53, 28% [MB]), delayed referral by the private practitioners (11, 7% [PB], 22, 12% [MB]) were the major reasons of delay. CONCLUSION: This study identified a vulnerable group - married and migrated males. Changing from annual screening to quarterly screening along with capacity building and awareness generation of the targeted population is the need of the hour for eradicating the disease.
