Objectives Methods Results Conclusion Our study aimed to evaluate the effect of superior hypogastric nerve plexus (SHNP) block in postoperative pain management in the first 24 h after minimally invasive gynecological (MIG) surgeries.We conducted a double‐blinded, randomized controlled trial in the Department of Obstetrics and Gynecology at a tertiary care centre from May 1, 2023 to September 30, 2023 in women undergoing major MIG surgeries. At the completion of the surgery, women were randomized to the intervention group who received SHNP block with ropivacaine 10 mL (0.75%) before port removal, whereas no intervention was taken in the control group. The extubation time was noted, and the pain score was assessed after 1, 2, 6, 12, and 24 h of extubation in the postoperative period using the visual analog scale (VAS). Statistical analysis was done, with a significance level of 0.05, to test the differences between the two groups.A total of 64 patients were randomly allocated to intervention and control groups. The median pain score was lower at 1 and 2 h post‐extubation and comparable between the two groups at 6, 12, and 24 h. The surrogate markers that is need for additional analgesia and duration of stay did not differ significantly in the two groups, with P‐values of 0.08 and 0.943, respectively.Although the SHNP group experienced considerably lower immediate postoperative pain levels in the initial hours following extubation, the impact of this benefit remains uncertain in the longer postoperative period. The effectiveness of this modality for pain control needs further study, particularly at later postoperative hours. [ABSTRACT FROM AUTHOR]

Background: Spinal anesthesia is the most popular regional anesthesia technique for lower limb and lower abdominal surgery. Bupivacaine 0.5% heavy is commonly used for intrathecal use. New long-acting local anesthetic agents such as ropivacaine have claimed benefits of reduced cardiac toxicity on overdose and more specific effects on sensory rather than motor nerve fibers. The use of intrathecal hyperbaric ropivacaine is not much studied. With this background, we studied intrathecal ropivacaine hyperbaric 0.75% against intrathecal bupivacaine hyperbaric 0.5% for lower abdominal and lower limb surgery. Aims and Objectives: To note the effectiveness of intrathecal ropivacaine and bupivacaine on characteristics of subarachnoid block such as sensory block, motor block, hemodynamic parameters, and complications if any. Materials and Methods: We randomized patients undergoing lower abdominal surgeries and lower limb orthopedic surgeries under spinal anesthesia into two groups so as to receive intrathecal either ropivacaine 0.75% hyperbaric (3 mL) or bupivacaine 0.5% hyperbaric (3mL) and noted study parameters. Results: Time of sensory block onset (P=0.0005), peak sensory level (P=0.0029), and onset of L1 bromage-3 motor block (P=1.27E--08) was significantly delayed in the ropivacaine group as compared to bupivacaine group. However, maximum sensory level achieved (T6), time required for two-segment sensory regressions (P=0.1162), and time of onset of pain (P=0.1162) were comparable in both groups. Conclusion: Intrathecal ropivacaine 0.75% hyperbaric produced slow onset sensory and motor block than 0.5% hyperbaric bupivacaine with comparable cephalic spread and duration of sensory block.

This article, published in the Indian Journal of Medical & Paediatric Oncology, explores the mechanism of resistance to the drug imatinib in patients with chronic myeloid leukemia (CML) blast crisis. The study focuses on the role of β1-integrin, a protein that is found at reduced levels in imatinib-resistant cells. The researchers found that knocking down β1-integrin in imatinib-sensitive cells led to the activation of signaling pathways associated with resistance. Additionally, the study revealed that amplification of the PLAG1 gene in resistant cells contributed to reduced levels of β1-integrin. Overall, the research provides insights into the Bcr-Abl-independent mechanism of resistance in CML blast crisis. [Extracted from the article]

Introduction: The relevance of plasma cells in the allograft liver is of utmost importance and objective assessment of these infiltrates and correlation with other ancillary findings needs to be evaluated. Materials and Methods: Three hundred and sixty‑eight graft liver biopsies received in the department from 2012 to 2022 and 115 allograft liver biopsies with histopathological diagnosis of rejection were selected. Based on plasma cells percentage in the portal tracts, the biopsies were divided into three groups: Group 1 showing not more than an occasional plasma cell, Group 2 showing <10% plasma cells, and Group 3 showing >10% plasma cells. Rejection activity index (RAI), portal/lobular inflammation, interface activity, subendothelial inflammation (portal and central vein), duct damage/loss, presence of cholestasis, apoptosis, perivenulitis, necrosis, rosette along with serial liver function tests (LFTs), and patient status at 1 year of follow‑up were recorded and compared between the groups. Results: Plasma cell infiltrates were observed in 52.6% of the specimens, with the mean percentage of plasma cells in the infiltrates being 4.9. Increased plasma cell infiltrates were associated with higher RAI scores, marked duct damage, marked portal and central vein endotheliitis, marked portal inflammation, and presence of interface activity. Higher levels of transaminitis were recorded at the time of biopsy, but no significant association was observed in the fall of serial LFTs over a 2‑week period with the presence of plasma cells. Conclusion: Identifying plasma cell infiltrates in liver allografts can serve as a clue toward increased severity of rejection in liver allograft biopsies. Further studies with emphasis on correlation with the clinical outcome and response to treatment are needed to validate its utility as an objective tool. [ABSTRACT FROM AUTHOR]

Occupational noise-induced hearing loss prominently occurs due to unavoidable sound frequencies mainly in the range of 3000 to 6000 Hz. This frequency region thus holds great importance for acoustic insulation. Polymeric foams with open cellular frameworks are mostly employed for sound absorption in these frequency regions. To enhance their sound-absorbing ability, nanofillers are integrated with the polymeric matrix. However, the majority of the incorporation methods result in a single-phased porous structure, which limits their potential. Herein, an altered method of modification of multiwall carbon nanotubes (MWCNTs) is explored for the preparation of modified polyurethane foam via a simple one-pot immersion-hydrothermal-evaporation method. A unique self-assembled nanolayered structure with nanopores was fabricated through optimized experimental conditions resembling a double three-dimensional form. This gave rise to an additional resonating-type structure within the porous-type matrix. Thus, a hybrid-type sound-absorbing material with distinctive structure was fabricated which could help achieve focused sound absorption ability at the desired frequency. The sound pressure level evaluated at a frequency of 4000 Hz was found to improve through incorporation of 0.5 wt % modified CNTs. The mean percentage enhancement in sound isolation for treated foam in comparison to untreated foam is 15 to 20% at 4000 Hz. The development of distinctive structures within the polymeric framework opens up a plethora of horizons that could be employed at the industrial level as well, and such structures could be engaged for achieving other eccentric properties, which would further enhance their applicability.

Microfluidic based sensors are one of the emerging alternatives for bringing solutions studies on paper platforms. Microfluidic paper assisted platform was developed over here through a simple, easy, cost effective and instrument free process. The self‐same method of waxing through crayoning, was estimated thoroughly on different paper platforms. Varied parameter including type of crayoning, way of patterning, color effect, wicking rate and channel optimization was performed on paper milieus. Optimized time of baking for obtaining controlled penetration ranges from 2 min to 8 min depending on the type of paper used. Wax crayoning was preferred over oil pasteling for making hydrophobic barriers uniformly, solid as well fully penetrated within paper inner layers. Fabrication through this easy cost‐effective route allows a formation of hydrophilic reaction or sensing zone of 0.25 cm2 with sufficient reactive area. Further sensing of dopamine on paper platform was carried using paper chip adsorbed with fluorescent modified graphene quantum dots as sensing material. The patterned paper showed advantage as only few microliter (5 μl to 10 μl) range of sample volume was required for testing. Fluorescence quenching with increase of concentration was witnessed where around 25–75 μM dopamine concentration was positively tested through naked eye; which for the first time was demonstrated here via robust wax crayoning method for developing paper based biosensor.

Introduction: Open fractures of the distal femur are a uncommon and intricate type of injury that typically occur in individuals who have sustained multiple traumas. These types of fractures are often accompanied by bone loss, contamination, damaged soft tissue, and a patient's overall poor health condition. The purpose of this study is to examine the outcomes of patients who were treated for open distal femur fractures using a staged protocol, which involves initial external fixation with debridement, followed by definitive fixation using an anatomical locking plate and bone grafting at a later stage. Method: The study included a group of 20 patients of open distal femurfractures who were operated with temporary external fixator and later on converted to definitive fixation with condylar locking plate with bone grafting. These patients were operated with our staged protocol and clinical outcome was evaluated using the functional evaluation scoring system by Sander's et al and Knee Society Scoring. Out of these 20 patients, 1 was lost to follow up at 3 months and 2 others were lost to follow up at 6 months. These 3 were excluded from our study. Results: Fracture union was seen in all 17 patients. The average time to union was 22.65+3.3 weeks. Two patients were complicated with infection and delayed union. Ilizarov application was doneto achieve union and gain length once the infection subsided. Conclusion- Staged protocol of temporary external fixator followed by definitive fixation with condylar locking plate and bone grafting is a safe and reliable method for the management of open distal femur fractures.

Calculus in the urethra of the female is very unusual. The patient remains asymptomatic or uncommonly presents with symptoms of dysuria, post-void urinary dribbling, and dyspareunia. If asymptomatic, it can be diagnosed incidentally on gynecological examination. Being hard in consistency, it may mimic metastatic lesion. We present a case of a female who presented to us for management of ovarian mass. On routine examination there was a hard mass in her vagina which was suspected to be a metastatic lesion. This mass on evaluation came out to be a urethral diverticulum with a large calculus. Very large urethral calculus are a very rare presentation in a female. [ABSTRACT FROM AUTHOR]

Simple Summary: The treatment for advanced and metastatic esophagogastric malignancies has historically required time-intensive multi-agent chemotherapy regimens, where patients spend time away from home to engage in therapy administrations and supportive care. With the addition of immunotherapies to the standard of care, the authors completed this study to estimate the time spent in health care across various systemic treatment regimens. The authors estimated the time toxicity, or the days spent in health care facilities, due to cancer diagnosis and treatment with immunotherapy- and chemotherapy-based treatment regimens for esophagogastric cancers. (1) Background: The purpose of this study was to evaluate the time toxicity, or time spent in health care, of immunotherapy- versus chemotherapy-based regimens for metastatic esophageal and gastric cancers. (2) Methods: A literature search was conducted, and 18 phase III clinical trials of immune checkpoint inhibitors were selected for analysis. Health care days were calculated based on the number of days associated with receiving therapy and the adverse events reported in the clinical trials. Both the number of health care days and the median overall survival were compared among chemotherapy-only, immunotherapy-only, and chemo-immunotherapy regimens across this cohort of drug registration trials. (3) Results: The estimated median number of health care days was 37 (range of 7–52) days, or 1.2 (range of 0.2–1.7) months, compared to a median survival of 10.2 months across these 18 studies. For the chemotherapy-only regimens, the median number of health care days was 39 (range of 21–51) days, and for chemo-immunotherapy, it was 39 (range of 30–52) days. The immunotherapy-only regimens had fewer days, a median of 28 (range of 24–41), p < 0.05, compared to the other two arms. (4) Conclusions: The chemo-immunotherapy regimens did not add time toxicity compared to chemotherapy alone. The immunotherapy-only regimens had lower time toxicity compared to chemotherapy alone. In the setting of decreased time toxicity and improved overall survival, further development of immunotherapy-based regimens could improve outcomes in advanced esophageal and gastric cancers.

New avenues for research have opened, which assess the influence of systemic disease on periodontium and vice versa. To find the correlation between polycystic ovary syndrome (PCOS) and periodontium by assessing clinical parameters [plaque index (PI), probing depth, periodontal disease index (PDI)] and the anthropological parameter [body mass index (BMI)] and to find the correlation between body mass index and periodontal disease index in subjects with and without PCOS. Sixty females comprising 30 with PCOS and 30 without PCOS were selected. Clinical, anthropological, and radiological assessment was done. Double blinding was incorporated. There was a statistically highly significant difference in mean age, mean PI, and mean PDI (P < 0.001) in PCOS group when compared to those without PCOS group by unpaired t-test for inter-group analysis. A statistically significant difference was found in mean probing depth and mean BMI (P < 0.05) in PCOS group when compared to those without PCOS group by unpaired t-test for inter-group analysis. No statistically significant correlation was found between mean PDI and mean BMI in PCOS and non-PCOS group subjects using Spearman's rank correlation. Women suffering from PCOS may be at a heightened risk for developing periodontal disease as our study re-establishes this association with respect to some periodontal parameters. With such a result, general practitioners/gynecologists can be encouraged to refer cases of PCOS to periodontists for early detection, prevention of periodontal disease, and maintenance of periodontal health.

Mature cystic teratoma is a benign ovarian tumor that usually presents in reproductive-age females. This tumor usually presents with pain abdomen, bloating, and a lump. Hereby, we describe a case of an ovarian dermoid presented with features of intestinal obstruction secondary to ileo-dermoid fistula formation. A 55-year-old postmenopausal female presented with lower abdominal pain, nausea, vomiting, and the feeling of a lump in the abdomen. On evaluation and imaging, it was diagnosed as a large ovarian dermoid (with malignant transformation) with multiple fistulous communications with ileal loops. The patient was managed by laparotomy, total abdominal hysterectomy with bilateral salpingo-oophorectomy, bowel resection, and anastomosis. The patient was discharged in good condition. The rupture of malignant ovarian dermoid followed by enterodermoid fistula formation and intestinal obstruction is rare. Complete cytoreduction and bowel repair should be considered for optimal results. [ABSTRACT FROM AUTHOR]

Background Post–kala-azar dermal leishmaniasis (PKDL) is a dermal complication of visceral leishmaniasis. Oral miltefosine (MF) is the first-line treatment for PKDL patients in South Asia. This study assessed the safety and effectiveness of MF therapy after 12 months of follow-up to explore more precise data. Methods In this observational study, 300 confirmed PKDL patients were enrolled. MF with the usual dose was administered to all patients for 12 weeks and followed up for 1 year. Clinical evolution was recorded systematically by photographs at screening and at 12 weeks, 6 months, and 12 months after treatment onset. Definitive cure consisted of disappearance of skin lesions with a negative PCR at 12 weeks or with >70% of lesions, disappearing or fading at 12-month follow-up. Patients with reappearing clinical features and any positive diagnostics of PKDL during the follow-up were considered as nonresponsive. Results Among 300 patients, 286 (95.3%) completed 12 weeks of treatment. The per-protocol cure rate at 12 months was 97%, but 7 patients relapsed and 51 (17%) were lost to 12-month follow-up, resulting in a final cure rate of only 76%. Eye-related adverse events were noted in 11 (3.7%) patients and resolved in most (72.7%) within 12 months. Unfortunately, 3 patients had persistent partial vision loss. Mild to moderate gastrointestinal side effects were seen in 28% patients. Conclusions Moderate effectiveness of MF was observed in the present study. A significant number of patients developed ocular complications, and thus MF for treatment for PKDL should be suspended and replaced with a safer alternative regimen. [ABSTRACT FROM AUTHOR]

Objective: To identify the potential determinants of tobacco counseling implementation among oral health professionals in India. Material and Methods: A cross-sectional survey was carried out among the 298 dentists of Aligarh and Gwalior. The questionnaire used in the study had sections on dentists' sociodemographic data and a 35-item questionnaire to assess the potential determinants of tobacco cessation counseling. Descriptive statistics were carried out, and a Chi-square test was utilized to determine the association. P-value <0.05 was considered statistically significant. Results: Domains "knowledge", "Professional Responsibility and Identity", and "Remembrance, awareness, and judgment" showed a statistically significant correlation with most tobacco cessation counseling behaviors. In addition, undergraduate education received in Tobacco Cessation counseling, and Continuing education received in Tobacco Cessation counseling had significantly impacted the practice of tobacco cessation counseling (p=0.02 and 0.04, respectively). Conclusion: This study suggests that "Knowledge", "Professional Responsibility and Identity" and "Remembrance, awareness, and judgment" are the potential determinants that could be used to design effective strategies to enhance tobacco counseling among dentists in India.

Factor VIII (FVIII) replacement and emicizumab are effective at preventing bleeds in patients with hemophilia A (HA). Though benefits of emicizumab among inhibitor patients with HA (PwHA) are well established, more real-world evidence among non-inhibitor patients is needed. Using a United States healthcare claims database, we compared billed annualized bleed rates (ABRb) and the total cost of care (TCC) before and after switching from FVIII prophylaxis to emicizumab among non-inhibitor male PwHA. Bayesian inferences were used to assess the difference in ABRb and TCC per patient per year (PPPY) pre- versus post-prophylaxis switch. We included 101 non-inhibitor male PwHA aged between 3 and 63 years old who switched from FVIII prophylaxis to emicizumab prophylaxis in 2018 or 2019. The ABRb increased from 0.52 to 0.62 (p = 0.83) after switch. The posterior probability of the mean ABRb increasing after the switch was 75.54%. The TCC PPPY increased from $517,143 to $627,005 (p < 0.0001) after switch and the posterior probability of mean costs increasing after the switch was 99.80%. Personalization of care through the identification of the most appropriate therapy for each patient can optimize clinical and economic outcomes. Future real-world evidence research could help establish the value of prophylactic options in targeted populations such as the non-inhibitor male PwHA. [ABSTRACT FROM AUTHOR]

Background Recent trials testing immune-checkpoint inhibitors in esophago-gastric malignancies have shown mixed results. We aim to assess key subgroups using the ASCO Net Health Benefit Score (NHBS) and ESMO Magnitude of Clinical Benefit Scale (MCBS). Materials and Methods A search for phase III trials of FDA-approved anti-PD-1 or anti-PD-L1 drugs in esophago-gastric cancer trials was identified using www.clinicaltrials.gov. These published studies were scored using the ASCO NHBS and ESMO MCBS. The ASCO NHBS scores were compared by primary site of cancer (esophageal vs gastric) and PD-L1 expression using the Mann-Whitney test and the ESMO-MCBS grading, by Fisher's Exact test. Results Fifteen of 45 clinical trials were included. Of them, 6 were primarily esophageal cancer trials, and 9 were primarily gastric cancer trials. Ten stratified their analysis based on PD-L1 expression. The ASCO NHBS score was higher (mean 40, range 20 to 56.6 vs. mean 12, range −1.1 to 18.4, P <.01) for esophageal cancer than gastric cancer. No difference was observed in survival and response endpoints between the 2 groups. Similarly, the ESMO MCBS scored higher for esophageal cancer group than gastric cancer (P <.05). Additionally, the scores were higher in those with high PD-L1 expression vs. low PD-L1 (mean 36, range 11.2-66.6 vs. mean 14, range −19.5 to 43.6, P <.05). Conclusion The ASCO NHB and ESMO scores were consistently higher among esophageal cancer trials than gastric cancer trials and in those with high PD-L1 expression than low expression. Histology and PD-L1 expression should be considered when discussing value of immunotherapy to patients. [ABSTRACT FROM AUTHOR]

The green, cost-effective and sustainable synthesis of nanomaterials has been a key concern of scientists and researchers. In this view, MNPs were prepared using a sapota plant leaf extract and the surface of the magnetite nanoparticles was engineered with unsaturated fatty acids. The first report on the effect of unsaturation on the size and magnetic properties of magnetite nanoparticles (MNPs), prepared by the co-precipitation method, has been studied by coating surfactants on MNPs based on their unsaturation from zero to three (lauric acid, oleic acid, linoleic acid, linolenic acid). The size effect and magnetic properties of MNPs coated with a surfactant have been studied in comparison with uncoated magnetite nanoparticles. After the surface modification of the magnetite particle, it is necessary to check whether the magnetic property has been restored or not. Therefore, the magnetic property was studied. The presence of a surfactant on the surface of MNPs was confirmed by Fourier-transform infrared spectroscopy (FTIR), which was later confirmed by scanning electron microscope (SEM) and thermogravimetric analysis (TGA). The atomic structure was studied by X-ray diffraction (XRD) and the size of uncoated and surfactant-coated MNPs was determined by transmission electron microscopy (TEM) and the Scherrer equation by following XRD data. The magnetization property was analyzed by a vibrating sample magnetometer (VSM) at 10, 100 and 300 K and both bared and surfactant-coated MNPs exhibited a superparamagnetic nature at room temperature. The saturation magnetization (Ms) study shows that MNPs coated with a surfactant have a lower saturation magnetization value in comparison to uncoated NPs, confirming surface layering. Because the magnetic fluid has been stabilized in the aqueous medium, the double-layer model is expected to prevail. [ABSTRACT FROM AUTHOR]

Factor VIII (FVIII) replacement and emicizumab have demonstrated efficacy for prevention of bleeds among patients with hemophilia A (PwHA) compared to on-demand (OD) use. Evidence investigating clinical outcomes and healthcare costs of non-inhibitor PwHA switching from prophylaxis with FVIII concentrates to emicizumab has not been well-established within large real-world datasets. This study aimed to investigate billed annualized bleed rates (ABRb) and total cost of care (TCC) among non-inhibitor PwHA switching from FVIII-prophylaxis to emicizumab-prophylaxis. This retrospective, observational study was conducted using IQVIA PharMetrics Plus, a US administrative claims database. The date of first claim for emicizumab was defined as the index date. OD patients and inhibitor patients were excluded. Bleeds were identified using a list of 535 diagnosis codes. Bayesian models were developed to estimate the probability ABRb worsens and TCC increases after switching to emicizumab. Wilcoxon rank-sum tests were used to test statistical significance of changes in ABRb and TCC after switch. Among the 121 identified patients, the difference in mean ABRb between FVIII-prophylaxis (0.68 [SD = 1.28]) and emicizumab (0.55 [SD = 1.48]) was insignificant (p =.142). The mean annual TCC significantly increased for patients switching from FVIII-prophylaxis ($518,151 [SD = $289,934]) to emicizumab ($652,679 [SD = $340,126]; p <.0001). The Bayesian models estimated a 21.0% probability of the ABRb worsening and a 99.9% probability of increasing TCC after switch. This study found that in male non-inhibitor PwHA, switching from FVIII prophylaxis to emicizumab incurs substantial cost increase with no significant benefit in ABRb. This evidence may help guide providers, payers, and patients in shared decision-making conversations around best treatment options. [ABSTRACT FROM AUTHOR]

Background: Melasma is the most common cause of facial melanosis and presents with a complex therapeutic problem. Intralesional platelet-rich plasma (PRP) has shown promising results in hyperpigmentation, whereas alphaglucoside derivative of trihydroxy benzoic acid (THBG) is a newer molecule for the management of pigmentation. Aims and objective: To compare therapeutic effects of PRP and THBG in facial melasma, note any untoward side effects of therapy and evaluate dermoscope as a tool for therapeutic prognosis. Methods: A total of 60 patients were enrolled based on inclusion and exclusion criteria after due written informed consent. After clinical, dermoscopic, and Wood lamp examination with relevant blood investigations, group P was treated by three sittings of intralesional injection of PRP at monthly interval, whereas group B was subjected to local application of THBG twice a day. Intergroup as well as intragroup comparative analyses were performed by subjective scores and dermoscope. Results: The mean of difference between modified melasma area and severity index (mMASI) score at the end of the study (i.e., difference mMASI at 12 and 0 weeks) was 2.21 for group P and 0.18 for group B and on comparison, the Pvalue was <0.0001 which is considered statistically significant. The average %mMASI improvement in group P was 35.05%, whereas in group B, it was 3.18%. On analysis of other parameters, physician global assessment, patient global assessment, and melasma quality of life scale patients of group P showed higher and significant improvements in comparison with group B. Changes in dermoscopic parameters could be appreciated in patients with significant improvement only. Conclusion: There is mild-moderate improvement in melasma (average 35.05%) with PRP with no untoward side effects, whereas THBG did not show any promising result in the treatment of melasma in FT grade IV/V.

Introduction: Tuberculosis (TB) is a significant cause of morbidity worldwide, especially in the low and middle-income countries like India and is found to be more common in the rural areas. Delays in diagnosis and initiation of treatment along with lower treatment adherence and completion rates have increased the morbidity and mortality of TB in the rural areas. The collation of information accumulated through the assessment of people's Knowledge, Attitude, and Practices (KAP) towards TB, helps in charting new health programs for the public, identifying lacunae, and devising interventions based on these lacunae which in turn will help us to achieve the vision of a "TB free India” by 2025. Aim: To find out KAP and any association amongst them regarding TB among the study subjects. Materials and Methods: This was a cross-sectional study conducted on patients attending Outpatient Department (OPD) at the Rural Health Training Centre (RHTC) attached to NCR Institute of Medical Sciences, Meerut, Uttar Pradesh, India, during January 2021 to April 2021. From a sample of 106 patients data of KAP regarding TB was collected via a structured questionnaire which was predesigned and pretested. Pearson’s Chi-square test was used to ascertain the association between subjects' KAP about TB. A p-value <0.05 was taken as the predictor of statistical significance. Results: Out of 106 patients, 72 (67.92%), 80 (75.47%) and 52 (49.06%) had adequate KAP respectively. Participants having adequate knowledge showed positive attitude and good practices and this association was found to be statistically significant. Conclusion: The study results reflect that having adequate knowledge of the disease transforms into good practices and a positive attitude towards a person suffering from the said disease as well as helps the people to have a positive frame of mind in case they themselves contract the disease. Health education and behaviour change communication hence needs to be scaled up in rural communities to prevent, detect and treat tuberculosis in order to achieve a TB free India.

Objective: To measure the anatomical dimensions of the vulva in adult Indian women. To analyze their correlations with age, body mass index (BMI), parity, and mode of delivery. Methods: This cross-sectional study was conducted in a tertiary care university hospital in India, among 400 women aged 18 years and above. Various vulval measurements were taken, and Pearson's correction was applied to variables like age, BMI, parity, and mode of delivery. Results: Mean length of glans of clitoris was 5.2 ± 1.43 mm, the labia minora width was 2.6 ± 0.74 cm, length of introitus was 1.3 ± 0.59 cm, and perineal body length was 2.3 ± 0.60 cm. The range of some measurements was extensive, for example labia minora width ranged from 0.7 to 4.9 cm. Normal centile curves were constructed for vulval measurements according to age groups. Statistically significant positive correlations of age, BMI, and obstetrical history were seen with labia minora width (r = 0.165, P = 0.001; r = 0.284, P < 0.001; r = 0.246, P < 0.001, respectively). Conclusion: The centile curves can be used as a reference for the Indian population of different ages. These can be used when counseling women coming for female genital cosmetic surgery.

Aim of the Study: The objective of this in-vitro study was to assess the screening capabilities of three endodontic sealers, namely the BioRoot RCS, the MTA Fillapex, and Sealapex (a calcium hydroxide-based sealer), and the gutta-percha cone by using a scanning electron microscopy to the dentine walls. The results from the research are presented here. Results: ZOE exhibited more gaps in the sealing materials evaluated with the least dental sealing performance, followed by the cervical third by the MTA Fillapex, the Sealapex, and the BioRoot RCS. The ZOE, followed by Sealapex, MTA Fillapex, and BioRoot RCS, exhibited inadequate dental wall sealing capacity in the middle of the third. The third apical ZOE exhibited more deficiencies in the formation of dental walls, followed by Sealapex, MTA Fillapex, and BioRoot RCS. Conclusion: Under the constraints of the investigation, it can be stated that for the bioceramic sealer, a minimal gap was seen, with RCS of BioRoot superior to Fillapex of MTA. In the middle third, Sealapex was better adapted to the calcium hydroxide-based sealant than the MTA Fillapex sealer. MTA Filllapex had lower gap development than Sealapex in cervical or apical thirds. [ABSTRACT FROM AUTHOR]

Introduction: Hemophilia B is associated with molecular heterogeneity, with more than 1200 unique variants in the F9 gene. We hereby describe the mutational spectrum of severe hemophilia B patients presenting in a tertiary‐care center in India. Method: DNA was extracted from peripheral blood samples of 35 diagnosed severe hemophilia B patients belonging to 32 families, and were subjected to Sanger sequencing. Determination of the effect of novel variants on the protein structure and correlation between genotype and phenotype was attempted using in‐silico tools. Results: Twenty‐seven different mutations were detected in 30 probands, including 20 known and 7 novel variants. Also, we found one suspected case of whole gene deletion. The serine peptidase domain harbored most of the variants (48.1%). Inhibitory antibodies were found in two patients. Conclusions: This study provides a comprehensive mutational spectrum and mutation screening strategy by Sanger sequencing of F9 gene in severe hemophilia B patients, in a resource‐constraint setting.

Background: Adolescents are at risk for mental health (MH) disorders but are unlikely to seek services and may be reluctant to talk about their MH. An anonymous, online MH-focused community could help reduce suffering. However, online forums can also promote negative behaviours such as cyberbullying. This study aimed to evaluate the safety and feasibility of an online community – LovesCompany – to improve MH outcomes for adolescents. Methods: American adolescents (14–17 years) were recruited through social media. Eligible participants were randomised to LovesCompany or a placebo MH resource site. Outcomes were assessed every other week for six months, and at twelve months. Multilevel models assessed group differences in depression, anxiety, and suicidal ideation. A subgroup of participants participated in qualitative interviews. Results: Participants (N = 202) were mostly female (70%), White non-Hispanic (69%), and cisgender (80%). There were no instances of inappropriate behaviour such as bullying or posting explicit content. Symptoms for both groups improved over time. Participants appreciated hearing others' experiences and valued the opportunity to offer support. Conclusion: Although adolescents are often resistant to MH treatment, they appear to be interested in anonymous, online, MH-focused conversation, and can benefit from giving and seeking support. Finding a balance between an appealing user experience, ethical considerations, and resource needs is challenging. [ABSTRACT FROM AUTHOR]

The discovery of human obesity-associated genes can reveal new mechanisms to target for weight loss therapy. Genetic studies of obese individuals and the analysis of rare genetic variants can identify novel obesity-associated genes. However, establishing a functional relationship between these candidate genes and adiposity remains a significant challenge. We uncovered a large number of rare homozygous gene variants by exome sequencing of severely obese children, including those from consanguineous families. By assessing the function of these genes in vivo in Drosophila, we identified 4 genes, not previously linked to human obesity, that regulate adiposity (itpr, dachsous, calpA, and sdk). Dachsous is a transmembrane protein upstream of the Hippo signalling pathway. We found that 3 further members of the Hippo pathway, fat, four-jointed, and hippo, also regulate adiposity and that they act in neurons, rather than in adipose tissue (fat body). Screening Hippo pathway genes in larger human cohorts revealed rare variants in TAOK2 associated with human obesity. Knockdown of Drosophila tao increased adiposity in vivo demonstrating the strength of our approach in predicting novel human obesity genes and signalling pathways and their site of action. This study set out to identify novel gene variants that may contribute to human obesity, by combining human exosome sequencing analyses with systematic functional screening in Drosophila. This identifies a number of novel obesity-associated genes which control adiposity in flies, and uncovers a potential role for the Hippo signaling pathway in obesity. [ABSTRACT FROM AUTHOR]
