Impact of manual dexterity on toothbrushing efficacy in typically developing children: A cross-sectional study.

BACKGROUND: Manual dexterity includes gross motor skills (GMS) and fine motor skills (FMS). Literature reports manual dexterity as a contributing factor for improved oral hygiene and that the required dexterity for toothbrushing develops above 8 years of age. Research suggests grip force, movement speed, and motor coordination should be assessed to improve knowledge on kinetics of brushing teeth. AIM: To assess the impact of manual dexterity on toothbrushing efficacy in 7 to 12 year old children. DESIGN: The cross-sectional study included 150 typically developing 7-12 year old children. Oral health status was recorded using the Decayed, Missing, and Filled Teeth index. GMS and FMS were evaluated using the MInnesota Manual Dexterity Test (MMDT) and Archimedes spiral test (AST), respectively. Toothbrushing efficacy was determined by Turesky modification of Quigley-Hein Plaque Index- difference in mean scores from before and after toothbrushing. RESULTS: Assessment of GMS, FMS, and toothbrushing efficacy using ANOVA showed a significant increase with age (p value: 0.000); unpaired t-test showed an association of toothbrushing efficacy with GMS and FMS irrespective of age (p value: 0.000). CONCLUSION: Manual dexterity was significantly associated with toothbrushing efficacy in typically developing children. AST, a simple test to determine FMS, may help paediatric dentists to guide parents on the supervision of toothbrushing for their child.

Maternal Colonization Versus Nosocomial Transmission as the Source of Drug-Resistant Bloodstream Infection in an Indian Neonatal Intensive Care Unit: A Prospective Cohort Study.

BACKGROUND: Drug-resistant gram-negative (GN) pathogens are a common cause of neonatal sepsis in low- and middle-income countries. Identifying GN transmission patterns is vital to inform preventive efforts. METHODS: We conducted a prospective cohort study, 12 October 2018 to 31 October 2019 to describe the association of maternal and environmental GN colonization with bloodstream infection (BSI) among neonates admitted to a neonatal intensive care unit (NICU) in Western India. We assessed rectal and vaginal colonization in pregnant women presenting for delivery and colonization in neonates and the environment using culture-based methods. We also collected data on BSI for all NICU patients, including neonates born to unenrolled mothers. Organism identification, antibiotic susceptibility testing, and next-generation sequencing (NGS) were performed to compare BSI and related colonization isolates. RESULTS: Among 952 enrolled women who delivered, 257 neonates required NICU admission, and 24 (9.3%) developed BSI. Among mothers of neonates with GN BSI (n = 21), 10 (47.7%) had rectal, 5 (23.8%) had vaginal, and 10 (47.7%) had no colonization with resistant GN organisms. No maternal isolates matched the species and resistance pattern of associated neonatal BSI isolates. Thirty GN BSI were observed among neonates born to unenrolled mothers. Among 37 of 51 BSI with available NGS data, 21 (57%) showed a single nucleotide polymorphism distance of ≤5 to another BSI isolate. CONCLUSIONS: Prospective assessment of maternal GN colonization did not demonstrate linkage to neonatal BSI. Organism-relatedness among neonates with BSI suggests nosocomial spread, highlighting the importance of NICU infection prevention and control practices to reduce GN BSI.

Transcriptional Analysis for Tuberculosis in Pregnant Women From the PRegnancy Associated Changes In Tuberculosis Immunology (PRACHITi) Study.

A new tuberculosis (TB) diagnostic cartridge assay, which detects a 3-gene TB signature in whole blood, was not diagnostic in women with maternal TB disease in India (area under the curve [AUC] = 0.72). In a cohort of pregnant women, we identified a novel gene set for TB diagnosis (AUC = 0.97) and one for TB progression (AUC = 0.96).

Cervicovaginal microbiota isolated from healthy women exhibit probiotic properties and antimicrobial activity against pathogens isolated from cervical cancer patients.

Abnormal cervicovaginal microbiota play an important role in HPV persistence and progression to cervical cancer. The present study aimed at isolating and identifying potential probiotics from vaginal swabs of healthy women and evaluating their activity against vaginal pathogens isolated from cervical cancer patients. Based on probiotic, acid-bile tolerance and antimicrobial properties, 13 lactic acid bacteria (LAB) from the healthy group were identified by MALDI TOF MS (Matrix Assisted Laser Desorption and Ionisation, Time Of Flight Mass Spectrometry). Among these, four strains, Lactobacillus gasseri P36Mops, Limosilactobacillus fermentum P37Mws, Lactobacillus delbrueckii P31Mcs and Enterococcus faecium P26Mcm, exhibited significant antimicrobial activity against 8 vaginal pathogens (Staphylococcus haemolyticus P41Tcs, Escherichia coli P30Tcs, E. coli P79Bcm, Enterococus faecalis P29Mops, E. faecalis P50Tws, E. faecalis P68Tcb, S. haemolyticus P48Bcb and S. haemolyticus P58Bcb) isolated from precancerous and cervical cancer patients. 16S rRNA sequencing of four potential probiotics revealed congruency with the MALDI-TOF MS identification and phylogenetic analysis showed genetic relationship with previously reported LAB strains. The selected LAB showed strain specific hydrophobicity (35.88-56.70%), auto-aggregation (35.26-61.39%) and antibiotic susceptibility. Interestingly, L. gasseri P36Mops was resistant to five standard antibiotics routinely used against urogenital or vaginal infections. LCMS (Liquid Chromatography Mass Spectrometry) analyses of the CFS (cell-free supernatant) of the four potential probiotics revealed the presence of metabolites such as N-(1-deoxy-1-fructosyl)valine, hygroline, acetoxy-2-hydroxy-16-heptadecen-4-one, avocadyne 4-acetate, avocadyne 2-acetate, taraxinic acid glucosyl ester, 6-hydroxypentadecanedioic acid, with reported antimicrobial activity. The overall data suggest the bio-therapeutic potential of the identified vaginal probiotics against cervical cancer-associated pathogens.

Effects of Pregnancy and Isoniazid Preventive Therapy on Mycobacterium tuberculosis Interferon Gamma Response Assays in Women With HIV.

BACKGROUND: Pregnancy is accompanied by immune suppression. We hypothesized that Mycobacterium tuberculosis-specific inflammatory responses used to identify latent tuberculosis infection (LTBI) lose positivity during pregnancy. We also hypothesized that isoniazid preventive therapy (IPT) may revert LTBI diagnoses because of its sterilizing activity. METHODS: 944 women with human immunodeficiency virus infection (HIV) participating in a randomized, double-blind, placebo-controlled study comparing 28 weeks of IPT antepartum versus postpartum, were tested by QuantiFERON-gold-in-tube (QGIT) antepartum and by QGIT and tuberculin skin test (TST) at delivery and postpartum. Serial QGIT positivity was assessed by logistic regression using generalized estimating equations. RESULTS: From entry to delivery, 68 (24%) of 284 QGIT-positive women reverted to QGIT-negative or indeterminate. Of these, 42 (62%) recovered QGIT positivity postpartum. The loss of QGIT positivity during pregnancy was explained by decreased interferon gamma (IFNγ) production in response to TB antigen and/or mitogen. At delivery, LTBI was identified by QGIT in 205 women and by TST in 113 women. Corresponding numbers postpartum were 229 and 122 women. QGIT and TST kappa agreement coefficients were 0.4 and 0.5, respectively. Among QGIT-positive women antepartum or at delivery, 34 (12%) reverted to QGIT-negative after IPT. There were no differences between women who initiated IPT antepartum or postpartum. CONCLUSIONS: Decreased IFNγ responses in pregnancy reduced QGIT positivity, suggesting that this test cannot reliably rule out LTBI during pregnancy. TST was less affected by pregnancy, but had lower positivity compared to QGIT at all time points. IPT was associated with loss of QGIT positivity, the potential clinical consequences of which need to be investigated.

Validation of New Interactive Nutrition Assistant - Diet in India Study of Health (NINA-DISH) FFQ with multiple 24-h dietary recalls among pregnant women in Pune, India.

Adequate dietary intake is critical to prevent adverse pregnancy outcomes. India has a high burden of maternal and child morbidity and mortality, but there is a lack of adequate tools to assess dietary intake. We validate an FFQ, New Interactive Nutrition Assistant - Diet in India Study of Health (NINA-DISH), among pregnant women living with and without HIV in Pune, India. Women were selected from a cohort study investigating immune responses to HIV and latent tuberculosis during pregnancy. The FFQ was administered during the third trimester and validated against multiple 24-h dietary recalls (24-HDR) collected in second and third trimesters. Data for analysis were available from fifty-eight women out of seventy enrolled into this sub-study, after excluding those with incomplete data or implausible energy intake. The median (Q1, Q3) age of study participants was 23 (20, 25) years. Median (Q1, Q3) daily energy intakes were 10 552 (8000, 11 958) and 10 673 (8510, 13 962) kJ by 24-HDR and FFQ, respectively, with FFQ overestimating nutrient intake. Pearson correlations between log-transformed estimates from FFQ and 24-HDR for energy, protein, carbohydrate, fat, Fe and Zn were 0·47, 0·48, 0·45, 0·33, 0·4 and 0·54, respectively. Energy-adjusted and de-attenuated correlations ranged from 0·41 (saturated fat) to 0·73 (Na). The highest misclassification into extreme tertiles was observed for fat (22 %), saturated fat (21 %) and Na (21 %). Bias existed at higher intake levels as observed by Bland-Altman plots. In conclusion, NINA-DISH is a valid and feasible tool for estimating dietary intakes among urban pregnant women in Western India.

Genetic gain for rice yield in rainfed environments in India.

The complexity of genotype × environment interactions under drought reduces heritability, which determines the effectiveness of selection for drought tolerance and development of drought tolerant varieties. Genetic progress measured through changes in yield performance over time is important in determining the efficiency of breeding programmes in which test cultivars are replaced each year on the assumption that the new cultivars will surpass the older cultivars. The goal of our study was to determine the annual rate of genetic gain for rice grain yield in a drought-prone rainfed system in a series of multi-environment trials conducted from 2005 to 2014 under the Drought Breeding Network of Indian sites in collaboration with the International Rice Research Institute (IRRI). Our results show a positive trend in grain yield with an annual genetic yield increase of about 0.68 % under irrigated control, 0.87 % under moderate reproductive stage drought stress and 1.9 % under severe reproductive stage drought stress due to breeding efforts. The study also demonstrates the effectiveness of direct selection for grain yield under both irrigated control as well as managed drought stress screening to improve yield in typical rainfed systems. IRRI's drought breeding programme has exhibited a significant positive trend in genetic gain for grain yield over the years under both drought stress as well as favorable irrigated control conditions. Several drought tolerant varieties released from the programme have outperformed the currently grown varieties under varied conditions in the rainfed environments on farmers' fields.

Intensified Short Symptom Screening Program for Dengue Infection during Pregnancy, India.

Mosquitoborne diseases (e.g., malaria, dengue, and chikungunya) are endemic to India and pose diagnostic challenges during pregnancy. We evaluated an intensified short symptom screening program in India to diagnose dengue during pregnancy. During October 2017-January 2018, we screened pregnant women during antenatal surveillance for symptoms of mosquitoborne diseases (fever only, fever with conjunctivitis, fever with rash, or all 3 symptoms) within the previous 15 days. Of 5,843 pregnant women screened, 52 were enrolled and tested for dengue, chikungunya, and Zika viruses by using a Trioplex real-time reverse transcription PCR. Of 49 who had complete results, 7 (14%) were dengue positive. Of these ocular pain was seen in 4 (57%) and conjunctivitis in 7 (100%). Intensified symptom screening using conjunctivitis, in addition to rash, in pregnant women with fever might improve dengue case detection and can be included in routine symptom screening during pregnancy.

Genotype × environment interactions for grain iron and zinc content in rice.

BACKGROUND: Nutrient deficiency in humans, especially in children and lactating women, is a major concern. Increasing the micronutrient concentration in staple crops like rice is one way to overcome this. The micronutrient content in rice, especially the iron (Fe) and zinc (Zn) content, is highly variable. The identification of rice genotypes in which there are naturally high Fe and Zn concentrations across environments is an important target towards the production of biofortified rice. RESULTS: Phenotypic correlations between grain Fe and Zn content were positive and significant in all environments but a significant negative association was observed between grain yield and grain Fe and Zn. Promising breeding lines with higher Zn or Fe content, or both, were: IR 82475-110-2-2-1-2 (Zn: 20.24-37.33 mg kg-1 ; Fe: 7.47-14.65 mg kg-1 ); IR 83294-66-2-2-3-2 (Zn: 22-37-41.97 mg kg-1 ; Fe: 9.43-17.16); IR 83668-35-2-2-2 (Zn: 27.15-42.73 mg kg-1 ; Fe: 6.01-14.71); IR 68144-2B-2-2-3-1-166 (Zn: 23.53-40.30 mg kg-1 ; Fe: 10.53-17.80 mg kg-1 ) and RP Bio 5478-185M7 (Zn: 22.60-40.07 mg kg-1 ; Fe: 7.64-14.73 mg kg-1 ). Among these, IR82475-110-2-2-1-2 (Zn: 20.24-37.33 mg kg-1 ; Fe: 7.47-14.65 mg kg-1 ) is also high yielding with 3.75 t ha-1 . Kelhrie Cha (Zn: 17.76-36.45 mg kg-1 ; Fe: 7.17-14.77 mg kg-1 ), Dzuluorhe (Zn: 17.48-39.68 mg kg-1 ; Fe: 7.89-19.90 mg kg-1 ), Nedu (Zn: 18.97-43.55 mg kg-1 Fe: 8.01-19.51 mg kg-1 ), Kuhusoi-Ri-Sareku (Zn: 17.37-44.14 mg kg-1 ; Fe: 8.99-14.30 mg kg-1 ) and Mima (Zn: 17.10-45.64 mg kg-1 ; Fe: 9.97-17.40 mg kg-1 ) were traditional donor genotypes that possessed both high grain Fe and high Zn content. CONCLUSION: Significant genotype × location (G × L) effects were observed in all traits except Fe. Genetic variance was significant and was considerably larger than the variance of G × L for grain Zn and Fe content traits, except grain yield. The G × L × year variance component was significant in all cases. © 2020 Society of Chemical Industry.

Gender-based violence screening methods preferred by women visiting a public hospital in Pune, India.

BACKGROUND: Gender-based violence (GBV) is a major global public health concern and is a risk factor for adverse health outcomes. Early identification of GBV is crucial for improved health outcomes. Interactions with health care providers may provide a unique opportunity for routine GBV screening, if a safe, confidential environment can be established. METHODS: Between November 2014 and February 2015, a cross-sectional, observational study was conducted where women were interviewed about their opinions concerning GBV screening in a tertiary health care setting in Pune, India. Trained counsellors interviewed 300 women at different out-patient and in-patient departments using a semi-structured questionnaire. RESULTS: Twenty-three percent of these women reported experiencing GBV in their life. However, 90% of women said they had never been asked about GBV in a health care setting. Seventy-two percent expressed willingness to be asked about GBV by their health care providers, with the preferred provider being nurses or counsellors. More than half (53%) women reported face-to-face interview as the most preferred method for screening. There were no major differences in these preferences by GBV history status. CONCLUSIONS: Our study provides evidence for preferred GBV screening methods and optimal provider engagement as perceived by women attending a public hospital.

Role of pediatric dentist in West syndrome rehabilitation: A case report.

AIM: West syndrome is characterized by a triad of infantile spasms, arrested psychomotor development, and pronounced paroxysmal electroencephalogram (EEG) abnormalities, notably hypsarrhythmia. This case report aims to discuss the various considerations and strategies for the dental management of a child with West syndrome. METHOD AND RESULT: This report focuses on a case of a 5-year-old girl diagnosed with West Syndrome who presented for her first dental visit with complaints of pain and swelling in the right posterior tooth region for the past three weeks. Due to frequent seizure episodes, neuropsychomotor delay, and multiple dental treatment needs, comprehensive full-mouth rehabilitation was performed under general anesthesia. CONCLUSION: Awareness of syndromes like West syndrome equips dentists to better manage children with complex conditions. Additionally, parental counselling and early preventive measures can significantly reduce the added burden of dental diseases in these patients.

Efficacy of sucrose application in minimizing pain perception related to dental injection in children aged 3 to 9 years: a randomized control trial.

Background: Dental fear and anxiety are significant challenges in managing behavior in children. Oral administration of sucrose or sweet-tasting solutions has shown effectiveness in reducing procedural pain in infants and neonates. This study aimed to investigate whether pre-application of sucrose solution had an effect on minimizing pain perception during injection and to assess the potential impact of the child's age and sweet preference. Methods: A randomized control clinical trial was conducted on 60 children aged 3-9 years requiring buccal infiltration injections. Following parental consent, demographic data of the children were recorded. Sweet preferences was assessed using a modified forced-choice test. Children were equally and randomly allocated into study (sucrose) and control groups using a lottery method. Sucrose solution or distilled water, respectively, was applied to the lateral surface of the tongue for 2 min. Topical anesthetic was applied at the site of injection, followed by local anesthesia administration. The children rinsed their mouths thrice with water immediately after anesthetic injection. A video was recorded during injection which was then scored by three blinded examiners on the Sound Eye Motor (SEM) scale. The children also self-evaluated using Wong-Baker Faces Pain Rating Scale (WBFPS). Results: The mean SEM scores and WBFPS scores were analyzed using the Kruskall-Wallis test. The mean SEM score in the study group was 1.37 ± 0.61, compared to 3.17 ± 0.87 in the control group, showing a statistically significant difference (P < 0.001). Mean pain scores assessed by WBFPS in the study group were 0.60 ± 1.4, while in the control group, they were 6.27 ± 2.33, also showing a statistically significant difference (P < 0.001). Children with a sweet preference demonstrated a subjective reduction in pain perception. Conclusion: Application of sucrose before dental injections in children helps to minimize pain upon injection across all age groups.

Enhancing special care dentistry with waiting room based multisensory­adapted dental environment: A randomized controlled-trial.

AIM: To assess the effectiveness of waiting room based multisensory adapted dental environment (SADE) as a novel, non-invasive behavior management technique in alleviating anxiety levels in children with Down syndrome. MATERIALS AND METHODS: This study was conducted in the Department of Pediatric and Preventive Dentistry, D.Y. Patil University School of Dentistry, Nerul, Navi Mumbai. A total of 40 children between 8 and 13 years of age diagnosed with Down syndrome were included in our study. Prior to the first dental evaluation, they were divided equally into two groups using simple randomization via lottery system. Group A (Intervention group): Patients were subjected to a sensory adapted environment (SADE) in the waiting room for 10 min prior to dental evaluation. Group B (Control group): Patients were subjected to a regular dental environment (RDE) in the waiting room for 10 min prior to dental evaluation. Outcome parameters evaluated at baseline and post dental evaluation were anxiety and behavior, using a pulse oximeter and the Modified Venham's Scale respectively. Data were subjected to statistical analysis using SPSS version 21.0 (SPSS Inc. Chicago, IL). The 'p' value < .05 was taken as significant at 95% confidence interval. RESULTS: Mann-Whitney U test was used to carry out the inter group analysis which showed a significant increase in the heart rate (26.00, p = .00) in Group B and a significant decrease in the Modified Venham Scale score (90.00, p = .001) in Group A. The Wilcoxon Signed ranks test was used to carry out the intra group analysis for which a significant difference between the two time intervals for heart rate (-3.69, p = .00) and Modified Venham Scale score (-1.46, p = .03) was obtained in Group A whereas a significant difference was obtained only in the heart rate (-3.04, p = .002) in Group B. CONCLUSION: Multisensory-adapted dental environment (SADE) in the waiting room effectively improves behavior, reduces anxiety and sensory discomfort among children with Down syndrome.

Comparison of the Analgesic Duration Using Ultrasound-guided Popliteal Sciatic Nerve Block between Diabetics with Neuropathy and Nondiabetics without Neuropathy.

INTRODUCTION: In India, the prevalence of diabetes mellitus neuropathy was reported to be as high as 30%. Eight percentage of the diabetic population suffer from foot ulceration and 1.8% have amputations. Popliteal nerve block can be potentially used for foot and ankle surgery with several advantages. AIM: To compare analgesic duration of an ultrasound (US)-guided popliteal sciatic nerve block between diabetics with neuropathy and nondiabetics without neuropathy. PATIENTS AND METHODS: Participants were allocated into two groups for popliteal sciatic nerve blocks under US guidance. The primary outcome was the duration to onset of sensory and motor blockade. The secondary outcome was the duration to rescue analgesic and the visual analog scale scoring within 24 h. Hemodynamic outcomes were also monitored along with the above variables. RESULTS: It was observed that the onset of sensory blockade was faster in participants with diabetes mellitus with peripheral neuropathy as compared to the nondiabetic participants and the duration for onset of motor blockade in dorsiflexion was faster in diabetic patients as compared to the nondiabetic patients (17.48 ± 3.21 min). However, there was no significant changes when comparing the onset of duration to loss of plantar flexion, in diabetics (17.86 ± 2.29 min) versus in nondiabetics (18.51 ± 3.32 min). The duration for rescue analgesics was found to be longer in diabetic participants (13.19 ± 2.14 h) as compared to the nondiabetic participants (11.44 ± 1.86 h). No differences were observed in the hemodynamic changes and the complications associated with local anesthetics in either group. CONCLUSION: Diabetic patients with neuropathy have faster onset of blockade when compared to nondiabetic patients without neuropathy which may be due to the degenerative condition of the peripheral nerves in them. The hemodynamic parameters do not play a role in defining the outcome of the block.

Résumé Introduction:En Inde, la prévalence de la neuropathie liée au diabète sucré atteignait 30 %. Huit pour cent de la population diabétique souffrent d'ulcères du pied et 1,8 % sont amputés. Le bloc du nerf poplité peut être potentiellement utilisé pour la chirurgie du pied et de la cheville avec plusieurs avantages.Objectif:Comparer la durée analgésique d'un bloc du nerf sciatique poplité guidé par échographie (É.-U.) entre des diabétiques atteints de neuropathie et des non diabétiques sans neuropathie.Patients et méthodes:Les participants ont été répartis en deux groupes pour les blocs du nerf sciatique poplité sous la direction des États-Unis. Le critère de jugement principal était la durée jusqu'à l'apparition du blocus sensoriel et moteur. Le résultat secondaire était la durée nécessaire pour sauver l'analgésique et l'échelle visuelle analogique après 24 h. Les résultats hémodynamiques ont également été surveillés avec les variables ci-dessus.Résultats:Il a été observé que l'apparition du blocage sensoriel était plus rapide chez les participants atteints de diabète sucré avec neuropathie périphérique que chez les participants non diabétiques et (la durée d'apparition du blocage moteur en dorsiflexion était plus rapide chez les patients diabétiques que chez les patients non diabétiques (Cependant, il n'y a eu aucun changement significatif en comparant le début de la durée à la perte de flexion plantaire, chez les diabétiques (17,86 ± 2,29 min) versus chez les non diabétiques (18,51 ± 3,32 min). La durée des analgésiques de secours a été trouvée être plus longue chez les participants diabétiques (13,19 ± 2,14 h) par rapport aux participants non diabétiques (11,44 ± 1,86 h). Aucune différence n'a été observée dans les changements hémodynamiques et les complications associées aux anesthésiques locaux dans les deux groupes.Conclusion:Patients diabétiques atteints de neuropathie ont un début de blocage plus rapide que les patients non diabétiques sans neuropathie, ce qui peut être dû à l'état dégénératif des nerfs périphériques chez eux. Les paramètres hémodynamiques ne jouent aucun rôle dans la définition de l'issue du bloc.

Exploring the diversity of vaginal microbiota between healthy women and cervical cancer patients in India.

Introduction. Cervicovaginal diversity has been reported as a predictive biomarker for cervical cancer risk. We recently reported the bio-therapeutic potential of vaginal probiotics from healthy Indian women against vaginal pathogens, isolated from the invasive cervical cancer (ICC) patients.Gap Statement. The cervicovaginal microflora from cervical cancer patients has not yet been reported from Indian population.Aim. The present study aimed at comparing the cervicovaginal microbiome between healthy controls (HC) and ICC patients from the Indian population.Methodology. In total, 30 vaginal swabs (15 from HC and 15 from ICC) were subjected to 16S rRNA gene sequencing. Alpha diversity was evaluated by Shannon and Chao1 index; and beta diversity by principle coordinate analysis (PCoA) of weighted and unweighted UniFrac distances. The relative abundance of the microbial taxa was done according to linear discriminant analysis effect size (LEfSe).Results. Predominance of Staphylococcus spp. in ICC and Lactobacillus gasseri in HC groups was observed. Alpha-diversity was found to be higher in ICC as compared to HC but was statistically non-significant. LEfSe analysis revealed Bacteroides fragilis and Escherichia coli as the marker genera in ICC with a marked decrease in Lactobacillus sp. Contrarily, in HC, L. gasseri, L. iners and L. fermentum were found to be abundant.Conclusion. Differences in the vaginal microbiome between healthy and ICC women could help in the early prediction of cervical cancer risk and thus in designing prevention strategies.

Levels of Tektin 2 and CatSper 2 in normozoospermic and oligoasthenozoospermic men and its association with motility, fertilization rate, embryo quality and pregnancy rate.

PURPOSE: To compare the expression profiles of Tektin 2 and CatSper 2 motility proteins in the spermatozoa of normozoospermic and oligoasthenozoospermic men and determine its correlation with sperm motility, fertilization rate, embryo quality and pregnancy rate. METHODS: Tektin 2 and CatSper 2 protein expression was studied using Western Blotting and immunofluorescence. Tektin 2 and CatSper 2 protein levels were quantified by ELISA. RESULTS: Oligoasthenozoospermic men were found to have lower fertilization rates, poor embryo quality and lower pregnancy rates as compared to normozoospermic men. The levels of Tektin 2 and CatSper 2 are significantly lower in spermatozoa of oligoasthenozoospermic men as compared to normozoospermic controls; the levels were also lower in immotile fraction as compared to motile fraction of spermatozoa obtained from normozoospermic individuals. The levels of Tektin 2 and CatSper 2 were higher in individuals demonstrating sperm motility >60 % as compared to sperm motility <30 %. Tektin 2 but not CatSper 2 levels were positively associated with fertilization rate, embryo quality and pregnancy rate. CONCLUSION: Levels of Tektin 2 and CatSper 2 proteins are positively associated with sperm motility parameters. Measurements of Tektin 2 levels can be correlated with the clinical outcome of ICSI.

Infant Dietary Pattern and its Association with Early Childhood Caries in Preschool Children: A Cross-sectional Study.

Aim: This study aimed to investigate the associations between feeding and oral hygiene practices during the first year of life and caries prevalence in preschool children. Materials and method: A cross-sectional study was conducted on 420 children between the age-group of 3-5 years in Navi Mumbai, India. Dental caries experience was recorded using WHO criteria. A validated questionnaire with 34 questions was used for collecting information regarding feeding and oral hygiene practices. The data collected were analyzed using the Mann-Whitney U test, Kruskal-Wallis test, and Chi-square test. Results: Caries prevalence was high and statistically significant (p < 0.05) among those who were breastfed, fell asleep with a bottle in the mouth, fed with additional sugar in bottled milk, those who had a frequent sweet intake, and where infant's teeth were not cleaned soon after eruption. Conclusion: Determining the role of feeding practices on early childhood caries and intervention during early childhood seems to be the most appropriate action to ensure healthy dental habits throughout life. Clinical significance: A future direction for dentists to target preventive interventions in early childhood and incorporate cariogenicity of frequent infant feeding into sound recommendations for parents and caregivers.

Evaluation of the effectiveness of sucrose versus xylitol application in minimizing pain related to dental injection in 5-7-year-old children - A randomized controlled pilot study.

Background: Oral application of sweet-tasting solutions has found to be effective in minimizing pain on dental injection in children. Xylitol has never been tested in this regard. Aim: The aim of this study was to compare the effectiveness of prior application of sucrose versus xylitol solution in minimizing pain on dental injection in 5-7-year-old children. Settings and Design: This study was a randomized controlled clinical trial. Materials and Methods: Informed consent was taken. A total of 30 children who required maxillary buccal infiltration injection were selected. The children were randomly allocated into the sucrose group, xylitol group, or control group by lottery method. In the sucrose and xylitol groups, 30% sucrose or 30% xylitol solution was applied on the lateral surface of the tongue for 2 min. In the control group, distilled water was applied. In all the groups, the topical anesthetic was applied at the site of injection followed by buccal infiltration. A video was taken during injection, and the sound eye-motor (SEM) scale was recorded by a blinded examiner. Patients were asked to self-evaluate using the Wong-Baker Faces Pain Scale (WBFPS). Statistical Analysis: Mann-Whitney test was used to analyze the data. Results: There was a statistically significant difference in the WBFPS and the SEM score between the sucrose and the control group (P < 0.05) and the xylitol and control group (P < 0.05). No statistically significant difference was found between the sucrose and xylitol group. Conclusion: The application of xylitol solution before dental injection was as effective as sucrose solution in minimizing pain during the injection.

Effectiveness of an extraoral cold and vibrating device in reducing pain perception during deposition of local anesthesia in pediatric patients aged 3-12 years: a split-mouth crossover study.

Background: Local anesthetic injections may induce pain in children, leading to fear and anxiety during subsequent visits. Among the various approaches recommended to reduce pain, one is the use of a Buzzy Bee™ device that operates on the concept of gate control theory and distraction. The literature regarding its effectiveness during the deposition of local anesthesia remains limited; hence, the aim of the present study was to determine the efficacy of extraoral cold and vibrating devices in reducing pain perception during the deposition of local anesthesia. Methods: A split-mouth crossover study in which 40 children aged 3-12 years requiring maxillary infiltration or inferior alveolar nerve block for extractions or pulp therapy in the maxillary or mandibular posterior teeth were included. The control intervention involved the application of topical anesthetic gel for one minute (5% lignocaine gel), followed by the administration of local anesthetic (2% lignocaine with 1:80,000 adrenaline) at a rate of 1 ml/minute. Along with the control protocol, the test intervention involved using the Buzzy Bee™ device for 2 minutes before and during the deposition of the local anesthetic injection. The heart rate and face, legs, arms, cry, and consolability revised (FLACC-R) scale scores were recorded by the dentist to assess the child's pain perception. Results: The mean age of the participants in Group A and Group B was 7.050 ± 3.12 years and 7.9 ± 2.65 years respectively. A reduction in the mean heart rate and FLACC-R score was observed during the deposition of local anesthetic solution in the tissues when the Buzzy Bee™ was used in both groups at different visits in the same subjects (P < 0.05) The Buzzy Bee™ device was effective in reducing the heart rate and FLACC-R scores when used during maxillary infiltration and inferior alveolar nerve block local anesthesia techniques (P < 0.05). Conclusion: The use of extraoral cold and vibrating devices significantly reduces pain perception during local anesthetic deposition in pediatric patients. Considering the results of this study, the device may be incorporated as an adjunct in routine dental practice while administering local anesthesia in children.
