Abstract
In this study, we designed, synthesized and characterized a novel series of piperidine-dihydropyridine hybrid compounds and characterized them by 1H-NMR, 13C NMR, mass spectrometry (MS), and elemental analysis. Subsequently, we assessed their in vitro anticancer potentials against the human breast adenocarcinoma cell line MCF-7 and the lung cancer cell line A-549. Several of these compounds demonstrated significant activity, with IC50 values ranging from 15.94 μM to 48.04 μM for A-549 and 24.68 μM to 59.12 μM for MCF-7, when compared to the reference drug Cisplatin.Notably, a compound featuring a 3-fluoro substitution in the carboxamide series exhibited robust inhibitory effects, with an IC50 of 15.94±0.201 μM against A-549 cells and an IC50 of 22.12±0.213 μM against MCF-7 cells, respectively. Additionally, a compound containing a cyclobutyl ring displayed potent activity, with an IC50 of 16.56±0.125 μM against A-549 and an IC50 of 24.68±0.217 μM against MCF-7 cells, respectively. Furthermore, molecular docking studies against the Epidermal Growth Factor Receptor (EGFR) (PDB ID: 2J6M) revealed favourable binding scores and interactions, suggesting their potential as promising candidates for further investigation in the context of anticancer drug development.

Abstract
The vibronic structure and nuclear dynamics in the first five excited singlet electronic states of bithiophene (2T) are investigated here. Specifically, considerations are given to comprehend the first two structureless and broad electronic absorption bands and the role of nonadiabatic coupling in the excited state relaxation mechanism of 2T in the gas phase. Associated potential energy surfaces (PESs) are established by constructing a model vibronic coupling Hamiltonian using 18 vibrational degrees of freedom and extensive ab initio electronic structure calculations. The topographies of these PESs are critically examined, and multiple conical intersections are established. The nuclear dynamics calculations are performed by propagating wave packets on the coupled electronic manifold. The present theoretical results are in good agreement with the experimental observations. It is found that strong nonadiabatic coupling between the S1-S4 and S1-S5 states along totally symmetric modes is predominantly responsible for the structureless and broad first absorption band, and overlapping S2, S3, S4, and S5 states form the second absorption band. Photorelaxation from the highly excited S5 to the lowest S1 state takes place through a cascade of diabatic population transfers among the S1-S4-S5 electronic manifold within the first ∼100 fs. Totally symmetric C=C stretching, C-S stretching, C-H wagging, ring puckering, and inter-ring bending modes collectively drive such relaxation dynamics.

Abstract
Dibutyl phthalate (DBP) is a widely used plasticizer to make plastic flexible and long-lasting. It is easily accessible in a broad spectrum of environments as a result of the rising level of plastic pollution. This compound is considered a top-priority toxicant and persistent organic pollutant by international environmental agencies for its endocrine disruptive and carcinogenic propensities. To mitigate the DBP in the soil, one DBP-degrading bacterial strain was isolated from a plastic-polluted landfill and identified as Paenarthrobacter ureafaciens PB10 by 16S rRNA gene sequence-based homology. The strain was found to develop a distinct transparent halo zone around grown colonies on an agar plate supplemented with DBP. The addition of yeast extract (100 mg/L) as a nutrient source accelerated cell biomass production and DBP degradation rate; however, the presence of glucose suppressed DBP degradation by the PB10 strain without affecting its ability to proliferate. The strain PB10 was efficient in eliminating DBP under various pH conditions (5.0-8.0). Maximum cell growth and degradation of 99.49% at 300 mg/L DBP were achieved in 72 h at the optimized mineral salt medium (MS) conditions of pH 7.0 and 32 °C. Despite that, when the concentration of DBP rose to 3000 mg/L, the DBP depletion rate was measured at 79.34% in 72 h. Some novel intermediate metabolites, like myristic acid, hexadecanoic acid, stearic acid, and the methyl derivative of 4-hydroxyphenyl acetate, along with monobutyl phthalate and phthalic acid, were detected in the downstream degradation process of DBP through GC-MS profiling. Furthermore, in synchronization with native soil microbes, this PB10 strain successfully removed a notable amount of DBP (up to 54.11%) from contaminated soil under microcosm study after 10 d. Thus, PB10 has effective DBP removal ability and is considered a potential candidate for bioremediation in DBP-contaminated sites.

Abstract
The emergence of peptide-based functional biomaterials is on the rise. To fulfil this purpose, a series of amphiphilic peptides, such as H2N-X-Met-Phe-C12H25, where X = L-lysine (CP1), X = L-histidine (CP2), and X = L-leucine (CP3), have been designed, synthesised, purified and fully characterised. Herein, we reported peptide-based supramolecular hydrogels with antibacterial and anticancer activities. An attempt has been made to investigate the antibacterial properties of these peptide-based hydrogels against Gram-positive (S. aureus and B. subtilis) and Gram-negative (E. coli and P. aeruginosa) bacteria. Investigations show that the L-lysine containing gelator, CP1, is active against both Gram-positive and Gram-negative bacteria and the L-histidine containing gelator, CP2, selectively inhibits the growth of Gram-negative bacteria. Interestingly, the L-leucine containing gelator, CP3, does not show any antibacterial properties. Moreover, the L-lysine containing gelator exhibits the best potency. Generation of reactive oxygen species (ROS) is a probable way to damage the bacterial membrane. To explore the cytotoxic properties and to determine the efficacy of the synthesized compounds in inhibiting cell viability, a comprehensive investigation was performed using three distinct cell lines: MDA-MB-231 (human triple-negative breast cancer), MDA-MB-468 (human triple-negative breast cancer) and HEK 293 (human embryonic kidney). Remarkably, the results of our study revealed a substantial cytotoxic impact of these peptide gelators on the MDA-MB-231 and MDA-MB-468 cell lines in comparison to the HEK 293 cells. Caspase 3/7 activity is the possible mechanistic path to determine the apoptotic rates of the cell lines. This finding emphasizes the promising potential of these peptide-based gelators in targeting and suppressing the growth of human triple negative breast cancer cells, while showing non-cytotoxicity towards non-cancerous HEK 293 cells. In a nutshell, these peptide-based materials are coming to light as next generation biomaterials.

Abstract
Canine parvovirus-2(CPV-2) causes a highly contagious disease of dogs characterised by acute hemorrhagic gastroenteritis, lethargy, vomiting, fever and usually bloody or mucoid diarrhoea. In the present study, 41 faecal samples collected from dogs exhibiting the signs of fever, vomition, bloody or mucoid diarrhoea in Kolkata, India were screened by haemagglutination test and PCR for detection of capsid protein coding VP2 gene. The viral genotype was detected by multiplex PCR and analysis of partial VP2 gene nucleotide sequences of selected PCR products with bioinformatics tool. Thirteen (31.71%) samples were found positive with HA titre ≥ 32 whereas 28 (68.29%) samples were positive by PCR of VP2 gene indicating higher sensitivity of PCR. Highest occurrence of CPV-2 was observed in the age group of 1-6 months (80.65%) and non-descript breeds with no history of vaccination (85%). Three samples were antigenic type CPV-2a, rest were CPV-2b/CPV 2c. Six CPV sequences were found to be highly similar to published CPV 2c sequences in BLAST analysis revealing a maximum identity of 99-100% with other CPV-2c strains and clustered together with CPV-2c strains of India and other countries in phylogenetic analysis. The present study highlights the need for continuous monitoring of samples to detect gradual changes in circulating CPV-2 genotypes in India.

Abstract
Phthalates are a family of reprotoxicant compounds, predominantly used as a plasticizer to improve the flexibility and longevity of consumable plastic goods. After their use these plastic products find their way to the waste disposal sites where they leach out the hazardous phthalates present within them, into the surrounding environment, contaminating soil, groundwater resources, and the nearby water bodies. Subsequently, phthalates move into the living system through the food chain and exhibit the well-known phenomenon of biological magnification. Phthalates as a primary pollutant have been classified as 1B reprotoxicants and teratogens by different government authorities and they have thus imposed restrictions on their use. Nevertheless, the release of these compounds in the environment is unabated. Bioremediation has been suggested as one of the ways of mitigating this menace, but studies regarding the field applications of phthalate utilizing microbes for this purpose are limited. Through this review, we endeavor to make a deeper understanding of the cause and concern of the problem and to find out a possible solution to it. The review critically emphasizes the various aspects of phthalates toxicity, including their chemical nature, human health risks, phytoaccumulation and entry into the food chain, microbial role in phthalate degradation processes, and future challenges.

Abstract
Nanoscale self-assembly of peptide constructs represents a promising means to present bioactive motifs to develop new functional materials. Here, we present a series of peptide amphiphiles which form hydrogels based on β-sheet nanofibril networks, several of which have very promising anti-microbial and anti-parasitic activities, in particular against multiple strains of Leishmania including drug-resistant ones. Aromatic amino acid based amphiphilic supramolecular gelators C14-Phe-CONH-(CH2)n-NH2 (n = 6 for P1 and n = 2 for P3) and C14-Trp-CONH-(CH2)n-NH2 (n = 6 for P2 and n = 2 for P4) have been synthesized and characterized, and their self-assembly and gelation behaviour have been investigated in the presence of ultrapure water (P1, P2, and P4) or 2% DMSO(v/v) in ultrapure water (P3). The rheological, morphological and structural properties of the gels have been comprehensively examined. The amphiphilic gelators (P1 and P3) were found to be active against both Gram-positive bacteria B. subtilis and Gram-negative bacteria E. coli and P. aeruginosa. Interestingly, amphiphiles P1 and P3 containing an L-phenylalanine residue show both antibacterial and antiparasitic activities. Herein, we report that synthetic amphiphiles with an amino acid residue exhibit a potent anti-protozoan activity and are cytotoxic towards a wide array of protozoal parasites, which includes Indian varieties of Leishmania donovani and also kill resistant parasitic strains including BHU-575, MILR and CPTR cells. These gelators are highly cytotoxic to promastigotes of Leishmania and trigger apoptotic-like events inside the parasite. The mechanism of killing the parasite is shown and these gelators are non-cytotoxic to host macrophage cells indicating the potential use of these gels as therapeutic agents against multiple forms of leishmaniasis in the near future.

Abstract
The principal treatment for active tubotympanic CSOM is meticulous aural toilet and instillation of a topical antimicrobial agent. The aim of the study is to evaluate the current bacteriological profile of active tubotympanic CSOM and the sensitivity pattern to most of the currently available antibiotics. We conducted a prospective study in a tertiary care hospital in the northern part of West Bengal. Patients presenting with active tubotympanic CSOM who did not receive antimicrobial therapy in the last 21 days were included in the study. Middle ear discharge was collected by an ENT specialist under strict aseptic precautions. The isolates were grown on blood agar and identified according to standard microbiological and biochemical methods. The antibiotic sensitivity profile of the isolates was determined by Kirby-Bauer disc diffusion method on Mueller Hinton agar. Out of total 198 samples the commonest micro-organism isolated was Staphylococcus aureus (35.86%) followed by Pseudomonas aeruginosa (19.19%). Staphylococcus aureus was highly sensitive to linezolid and vancomycin followed by ciprofloxacin. Pseudomonas aeruginosa was highly sensitive to polymyxin B followed by meropenem, cefoperazone plus sulbactam, and ciprofloxacin. The present study indicates that there can be a variation in the bacterial aetiologies of CSOM and their sensitivity pattern due to widespread use of antibiotics. Hence it is prudent to conduct periodic evaluation of microbiological pattern and antibiotic sensitivity of CSOM.

Abstract
OBJECTIVES We aimed to evaluate blood pressure (BP) in Indian children who had similar demographic characteristics but hailed from different altitudes. METHODS BP of school going children, aged 5 to 12 years, at five different locations varying in altitude (near sea level: n = 425; 2000 feet: n = 244; 4000 feet: n = 248; 6000 feet: n = 242 and 8000 feet: n = 250) was measured in a mountainous district in Himalaya. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded by aneroid sphygmomanometer in the sitting posture using a calibrated instrument and four trained resident doctors. The average of three readings was taken. RESULTS Of the 1229 children whose data were analyzed, 50.4% were boys. SBP showed a progressive rise from 99.5 (4.00) mmHg [mean (standard deviation)] at near sea level to 106.7 (4.17) mmHg at 8000 feet. Similarly, DBP showed a rise from 60.1 (3.67) mmHg to 66.8 (4.58) mmHg over the same altitude range. Analysis of covariance for BP variation with altitude, with age as covariate, indicated a modest but statistically significant rise in both SBP and DBP with altitude. Higher BP values was noted among children residing at higher than at lower altitude (0.8% at sea level to 18.8% at 8000 feet). Correlations between SBP and DBP values and height and weight, though positive and significant at p < 0.01 level, were weak. CONCLUSIONS These data will help in correct interpretation of BP readings in children residing at high altitude.

Abstract
INTRODUCTION Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) has led to a terrifying global pandemic. The presentations in neonates are varied with less case severity compared to adults. AIM To describe the clinical and laboratory features and outcomes of neonates admitted with SARS-CoV-2 infection during the second surge of COVID-19 pandemic in a Government Medical College, West Bengal, India. MATERIALS AND METHODS It is a hospital-based observational cross-sectional study conducted in the newborn unit of Burdwan Medical College and Hospital between 1 April 2021 and 31 July 2021 including all SARS-CoV-2 Real time RT-PCR (Reverse transcriptase polymerase chain reaction) positive neonates. The demographic, clinical and laboratory characteristics of all the neonates and their outcomes were documented and analysed. RESULTS Twenty-two neonates were found to be SARS-CoV-2 RT-PCR positive out of which 9 (40.9%) were found to be asymptomatic and 6 (27.27%) required neonatal intensive care unit admissions. Among the symptomatic neonates, most common presentations were respiratory distress (40.9%) and gastrointestinal manifestations (40.9%). Eight (36.36%) neonates required respiratory support. Three (13.6%) neonates had pneumonia of which one had right middle lobe collapse. Laboratory parameters were nonspecific except for the two (9%) cases of multisystem inflammatory syndrome in neonates. High-resolution computed tomography findings in two cases were suggestive of SARS-CoV-2 infection-induced changes. Two (9%) neonates died of which one was likely due to SARS-CoV-2 infection. CONCLUSION Neonates with SARS-CoV-2 infection are mostly asymptomatic. However, clinicians must be vigilant as atypical presentations such as consolidation, collapse, meningitis or multisystem inflammatory syndrome may occur.

Abstract
Context: Currently, a major curricular reform in the form of competency-based medical education (CBME) curriculum is being rolled out across all medical colleges in India. However, it is important to find out and address the concerns of faculty regarding various aspects of this new curriculum. Aim: To analyze the concerns of the faculty members of medical colleges in India in response to the changes emerging from the adoption and implementation of the new curriculum through the concerns-based adoption model by applying the stages of concern (SoC) questionnaire. Methodology: A multicentric, cross-sectional quantitative study involving faculty members currently working in medical colleges and with more than 2 years of teaching experience was conducted using SoC questionnaire (SoCQ). The questionnaire was delivered as Google Form. Results: Of the 744 faculty participants, 41.1% (306) of faculty belonged to the 31–40 years age group followed by the 41–50 years age group (267, 35.9%). Respondents rated their level of concern differently among the seven SoC - percentile scores were highest in Stage 0– awareness (94) and least in Stage 4– consequences (59). An appreciably higher percentile scores were seen at the consequences stage (63 vs. 54), collaboration stage (80 vs. 68), and refocusing stage (77 vs. 69) in those faculty members who were trained in curriculum implementation support program (CISP) compared to the untrained group. However; the SoCQ profiles of CISP trained and untrained faculty were very much similar. SoCQ profiles of holders of advanced training in medical education and non-holders were also the same. Conclusion: Almost after 2 years of well-planned introduction of the CBME curriculum in India, the generalized faculty profile is still suggestive of interested but non-user type for the adoption of CBME. However; compared to untrained faculty, CISP trained faculty is more concerned about the impact of CBME on students, collaborating with colleagues for its proper implementation and exploring more benefits from the implementation of CBME, indicating that more hand-holding is required for faculty development beyond CISP.

Abstract
Background: Childhood pneumonia is one of the leading causes of mortality among under-five children. It is responsible for 15% of all deaths of children U5, killing 808,694 children in 2017 (1). Traditional visual inspection and manual count method is used to detect and classify fast-breathing, a key indicator of Pneumonia. In response to UNICEF’s call for a reliable diagnostic tool, Philips was the first to respond with the Children’s Automatic Respiratory Monitor for measuring fast breathing objectively. Aim: UNICEF and Philips Foundation initiated a field study to test the acceptability, usability and efficacy of the Automatic Respiratory Monitor in Determining Fast Breathing in low resource setting environments. Settings and Design: Philips Foundation partnered up with the Directorate of Medical Education in West Bengal, India to conduct the field study amongst community healthcare workers and beneficiaries in a rural district of West Bengal. In collaboration with North Bengal Medical College & Hospital, a community-based study was conducted in a tribal tea garden of Naxalbari block. Methods and Material: Acceptability and usability of the device was assessed through structtured interviews and dialogues with community health workers (CHWs), caregivers and local healthcare practitioners. Efficacy of the device was represented by the inter-rater agreement between the traditional visual inspection and manual count method and the device reading. Statistical Analysis Used: A descriptive community based mixed method study was conducted. Satisfaction among community healthcare workers (CHWs) and beneficiaries was found to be promising across all study parameters. Results and Conclusions: The paper captures the study methods, statistical analysis of the data, the conclusions, areas of further research and recommends community-wide use of the device in objectively measuring fast breathing among children under the age of five years.

Abstract
OBJECTIVE To explore association between serum ferritin and severity of sepsis among children, and relate levels to the final outcome. METHODS This observational study was conducted in a tertiary care hospital between I February and 30 July, 2019. Serum ferritin level was estimated in children (age 6 months to 12 years) suffering from sepsis, irrespective of the probable etiology. Children with hemoglobinopathies, autoimmune diseases, previous blood transfusion, severe acute malnutrition, hemophagocytic lymphohistiocytosis and chronic hepatitis were excluded. The ferritin level was measured sequentially at pre-defined stages of illness viz., sepsis, severe sepsis, septic shock and multiorgan dysfunction syndrome (MODS). Association between serum ferritin and severity of sepsis was analyzed, and ferritin level was related to the final outcome of death or recovery by receiver operating characteristic (ROC) curve analysis. RESULTS The study group included 47 children with sepsis who progressed to a state of MODS; 32 recovered from MODS. Significant differences in serum ferritin level were observed with severity of sepsis. There was clear demarcation of ferritin levels between sepsis severity stages. The proportion of death among the 47 MODS cases was 31.9% (95% CI 18.6 - 45.2%). ROC analysis in the MODS group indicated that serum ferritin >1994.3 ng/mL predicts mortality (AUC 0.73 [95% CI 0.58-0.85]) with sensitivity 66.7% [95% CI 38.4-88%] and specificity 100.0% [95% CI 89.1-100%]. CONCLUSIONS There is clear demarcation of serum ferritin levels that can help differentiation of sepsis severity stages in children with sepsis. There is no such demarcation between survivors and non-survivors in MODS cases.

Abstract
The toxic metalloid arsenic (As), is a major pollutant of soil and water, imposing severe health concerns on human lives. It enters the food chain mainly through As-contaminated crops. The uptake, translocation and accumulation of As in plant tissue are often controlled by certain soil-inhabiting microbial communities. Among them, indigenous, free-living As-resistant plant growth-promoting rhizobacteria (PGPR) plays a pivotal role in As-immobilization. Besides, the plant's inability to withstand As after a threshold level is actively managed by these PGPR increasing As-tolerance in host plants by a synergistic plant-microbe interaction. The dual functionality of As-resistant PGPR i.e., phytostimulation and minimization of As-induced phytotoxic damages are one of the main focal points of this review article. It is known that such PGPR having the functional arsenic-resistant genes (in ars operon) including As-transporters, As-transforming genes contributed to the As accumulation and detoxification/transformation respectively. Apart from assisting in nutrient acquisition and modulating phytohormone levels, As-resistant PGPR also influences the antioxidative defense system in plants by maneuvering multiple enzymatic and non-enzymatic antioxidants. Furthermore, they are effective in reducing membrane damage and electrolyte leakage in plant cells. As-induced photosynthetic damage is also found to be salvaged by As-resistant PGPR. Briefly, the eco-physiological, biochemical and molecular mechanisms of As-resistant PGPR are thus elaborated here with regard to the As-exposed crops.

Abstract
OBJECTIVE To assess macrophage activation syndrome (MAS) in septic shock leading to multiorgan dysfunction syndrome (MODS). METHODS A prospective observational study was conducted at a tertiary care hospital to evaluate the MAS criteria in different stages of sepsis. Children aged 6 months to 12 years in different stages of septic shock were recruited. The Paediatric Rheumatology International Trials Organisation Collaborative Initiative (PRINTO) criteria of MAS were applied initially at the stage of septic shock and subsequently at the stage of MODS (MODS cohort) or following recovery from septic shock without going through MODS (non-MODS cohort). RESULTS A total of 127 subjects were studied, with 53 comprising the MODS cohort and the rest 74 the non-MODS cohort. At the initial assessment, a comparable proportion of subjects in the MODS and non-MODS groups satisfied the MAS criteria (20.75% and 25.68%, respectively; p=0.529). However, by the time of progression to MODS, 81.13% of the subjects satisfied the MAS criteria in the MODS group, whereas only 16.18% subjects in the non-MODS group continued to satisfy the MAS criteria (p<0.001). Thus, there was a definite increase in the proportion of subjects showing MAS by the time they progressed to multiorgan dysfunction (p<0.001). In contrast, the proportion declined significantly (25.68% to 16.18%; p=0.008) in the subjects who had recovered. CONCLUSION The findings bear out the hypothesis that MODS in sepsis is a reflection of MAS secondary to sepsis. However, studies in larger cohorts are needed to validate these findings and explore the therapeutic implications.

Abstract
OBJECTIVES To determine the burden and etiological factors of leave against medical advice (LAMA) in Indian children. METHODOLOGY In this prospective study, legal guardians of 528 patients who took the decision of LAMA were interviewed (using structured question answers based multi-option) and data were captured over a period of 16 months. The resultant database was analyzed using standard statistical methods. RESULTS About 6.12% of childhood LAMA cases were dealt out of total pediatric admission including newborns. Neonatal preponderance noted in cases of LAMA from intensive care unit (ICU; 57.14%, p < 0.05). The overall male (n = 293) to female (n = 235) ratio in this study was 1.25:1. Number of LAMA patients was higher from rural area (83.33%), mostly admitted in ICU (93.65%, Pearson's chi-squared test, p < 0.05). Higher proportion (29.47%) of patients with infection availed LAMA from neonatal age group but overall LAMA patients fall under category of respiratory disorders (22.35%). Interest of the domestics issues other than suffering child was considered primary during LAMA for those admitted in ward as compared with ICU patients [odds ratio (OR): 1.73, CI: 1.02-2.94, p < 0.05]. ICU patients were reportedly to be taken to private health care facility (OR: 1.93, CI: 1.06-3.49, p < 0.05). Duration of stay before taking LAMA from ward was <7 days (85.59%, OR: 0.19, CI: 0.11-0.35, p < 0.05). Upper-lower socio-economic class attributed financial constraint as the main reason for LAMA (Pearson's chi-squared test, Chi-square value: 152.23, p < 0.05). CONCLUSIONS This study tried to elucidate the determinants of childhood LAMA in rural Indian setting.

Abstract
BACKGROUND To evaluate the utility of echocardiogram (ECHO) in detection and treatment of patent ductus arteriosus (PDA) and hemodynamically significant PDA (hsPDA) in preterm neonates. METHODS This was a retrospective case-control study of all preterm infants born or admitted to the level III Neonatal Intensive Care Unit in McMaster Children's Hospital from January 2009 to January 2013. These cases were further classified into the following sub-groups: group A) hsPDA confirmed on ECHO; and the control, group B) PDA (but not hemodynamically significant) confirmed on ECHO. Patients without an ECHO were excluded from all analyses. The primary outcome was incidence of treatment for PDA. RESULTS PDA treatment was administered in 83.3% and 11.2% of patients in groups A and B respectively (P < 0.05). Among patients with a hsPDA within group A, 17% did not receive treatment, while 11% of patients with non-hemodynamically significant PDA received treatment for the PDA. Within the cohort of patients who received treatment for a hsPDA, gestational age below 35 weeks as well as murmurs heard on auscultation were both found to be predictors of treatment. CONCLUSION While the ECHO remains the gold standard for detecting pathological PDA, there is evidence that other traditional clinical measures continue to guide clinical practice and treatment decisions. Further research is required to gain an understanding of how clinical measures and ECHO may be used in conjunction to optimize resource utilization.

Abstract
OBJECTIVE To delineate the pattern of joint involvement in neonatal septic arthritis, assess the prognosis, and determine significant predictors of unfavorable outcome. METHODS Subjects were recruited through purposive sampling after obtaining parental consent. A detailed history and examination findings with perinatal data were recorded. Ultrasound and magnetic resonance imaging data of affected joints and blood culture and aspirated joint fluid culture data were recorded along with management received. Cases were followed-up every 3 months from discharge up to minimum 12 months. An unfavorable outcome indicated by permanent joint deformity or restricted range of movement of the affected joint, limb length discrepancy, and persistent joint deformity upon radio imaging at the end of the follow-up period were also included. RESULTS The hip joint involvement (59.2%) was the commonest with predominance of the monoarticular pattern of affliction (74.4%). An overall outcome was favorable in 70.3% subjects with prompt diagnosis and management. A delay in seeking treatment was found to be an indicator of unfavorable outcome. In addition, disease detection by ultrasound at presentation predicted unfavorable outcome. CONCLUSION Neonatal septic arthritis is a rare disease with predominant hip or knee involvement. Outcome is favorable with early detection and institution of appropriate management. A delay in treatment worsens prognosis.

Abstract
The purpose of this study was to investigate parent reports of quality of life for their very young children with congenital heart defects (CHD) and to compare their scores to previously published data. Parents of children 1-3 years old with CHD or innocent heart murmurs completed the Pediatric Quality of Life Inventory (PedsQL) core, cardiac, and family impact modules. Multivariable regression analyses assessed the impact of age, sex, family income, and CHD treatment history (study group) on PedsQL scores. Correlations between family impact and core/cardiac modules were examined. PedsQL scores were compared to healthy norms. 140 parents of young children participated within four study groups: CHD no treatment (n = 44), CHD treatment without bypass (n = 26), CHD treatment with bypass (n = 42) ,and innocent heart murmurs (n = 28). Male sex was associated with higher core (F = 4.16, p = 0.04, σ2 = .03) and cardiac quality of life (F = 4.41, p = .04, σ2 = 0.04). Higher family income was associated with higher family quality of life (F = 8.89, p < .01, σ2 = 0.13). Parents of children with innocent heart murmurs and children with CHD not requiring treatment had higher core quality of life compared to young healthy children. Cardiac-related quality of life scores were associated with family impact (r = 0.68) and core module (r = 0.63) quality of life scores. Parents of very young children with CHD report good quality of life for their children and families. Quality of life exceeds in children with innocent murmurs or CHD not requiring repair. Parents report a lower quality of life among girls, and lower family quality of life is associated with lower family income.

Abstract
OBJECTIVE Hemophilia is a common X-linked recessive coagulopathy causing recurrent bleeding into the synovial joints and results in articular and periarticular abnormalities. To our knowledge, this is the first comprehensive study aimed at studying the clinico-radiological joint score evaluation in hemophilic arthropathy in children from a developing country and its possible impact on the quality of life. METHODS In this hospital-based, prospective, descriptive study, all children presenting to the pediatric rheumatology clinic were studied. The joint physical examination was scored using the Hemophilia Joint Health Score 2.1 (HJHS 2.1). The patients were then subjected to imaging of the most affected joint using ultrasonography (USG) and magnetic resonance imaging (MRI). Detailed USG and MRI radiological evaluation was recorded in the predesigned proforma using the Hemophilia Early Arthropathy Detection with Ultra Sound (HEAD-US) score and MRI DENVER score. The physical quality of life as per Functional Independence Score in Hemophilia (FISH) was noted. The clinical, radiological, and functional scores were analyzed with an appropriate statistical measure. RESULTS The mean age at presentation was 7.4 years (interquartile range 4.9-10), with the knee being the most common joint involved. All of the USG score, MRI score, and FISH score have a significant correlation (p<0.05), with the HJHS 2.1 score with correlation coefficients of 0.7086, -0.8916, and 0.8607, respectively. USG and MRI had a correlation coefficient of -0.7145 and -0.8326 with FISH, respectively. CONCLUSION The degree of association between HJHS 2.1 score was found to be maximum with HEAD-US score, whereas a negative correlation was seen evaluating FISH score with both HEAD-US and MRI DENVER scores. Use of these scores, specifically HEAD-US score, will result in consistent assessment of hemophilic joints, optimizing the management of the destructive changes.

Abstract
Intrauterine growth restriction (IUGR) is a condition which has been difficult to assess at an early stage, resulting in the delivery of children who have poor genetic growth potential. Currently, IUGR classification is based upon the system of ultrasound biometry. Doppler velocimetry allows the measurement of hemodynamic flow of major fetal vessels, comparing the flow indices and patterns of normal and IUGR cases. In this review, the effectiveness of Doppler velocimetry in assessing blood flow in major vessels including the umbilical artery, ductus venosus, and middle cerebral artery was studied for both diagnostic and prognostic screening of IUGR. The umbilical artery is the most frequently studied vessel in Doppler velocimetry due to its accessibility and the strength of its associations with fetal outcomes. Abnormalities in the ductus venosus waveform can be indicative of increased resistance in the right atrium due to placental abnormalities. The middle cerebral artery is the most studied fetal cerebral artery and can detect cerebral blood flow and direction, which is why these three vessels were selected to be examined in this context. A potential mathematical model could be developed to incorporate these Doppler measurements which are indicative of IUGR, in order to reduce perinatal mortality. The purpose of the proposed algorithm is to integrate Doppler velocimetry with biophysical profiling in order to determine the optimal timing of delivery, thus reducing the risks of adverse perinatal outcomes.

Abstract
BACKGROUND Koro, as a culture bound syndrome is predominantly reported from Asian countries. There is dearth of well-designed research focussing on course and outcome of Koro. METHOD In the index study, 64 consecutive consenting patients with symptoms of Koro reported in different disciplines of a tertiary care Government Hospital of West Bengal were recruited over a period of 3 months. They were treated by standard treatment protocol and followed up for next 3 months. Data was collected on clinical course and treatment outcome by a pretested semi-structured proforma, specially developed for this study. RESULTS A typical subject was a young single male, educated up to primary standard, agricultural worker by occupation and belonged to Hindu rural joint family. Among the whole sample 23% were female. Majority were referred from either private doctors or hospitals or government hospitals and reported first at non-psychiatric OPD. Dropout and recovery rates were 28% (male 33%, female 13%) and 89% (male 89%, female 92%) respectively. 20%, 75%, 9%, 31%, 19% of patients needed indoor admission, oral anxiolytics, injectable tranquilizers, specific pharmacological and psychosocial treatment, supportive medical treatment respectively. There was a subtle difference in course and treatment outcome noted between the genders. A new modality of psycho-sexual intervention 'sex education in vivo' was applied on patients of Koro with favourable result. CONCLUSION Female counterpart represented a significant proportion. Overall improved trend of utilizing medical care facilities was observed. But sceptical attitude towards Psychiatric treatment is prevailing. An overall good treatment outcome was noted among the Koro victims.

Abstract
An ab initio quantum dynamics study has been performed to explore the distinct structural symmetry of C(CH3)4(+) in the ground electronic state compared to CH4(+). Additionally, the underlying details of the highly diffuse and complex vibronic structure of the first photoelectron band of C(CH3)4 have been investigated. Associated potential energy surfaces over the two-dimensional space of nuclear coordinates, subject to the T2⊗ (e + t2) Jahn-Teller effect, are established from extensive electronic structure calculations and (then) the nuclear dynamics calculations are done on them via wave packet propagation including the nonadiabatic coupling of the three electronic sheets. The theoretical results are in good agreement with experimental observations. The JT stabilization energies due to T2⊗e, T2⊗t2 and T2⊗ (e + t2) distortions in the X[combining tilde](2)T2 electronic manifold of C(CH3)4(+) illustrate that the highest stabilization occurs through the T2⊗t2-JT distortion (in the ground state of C(CH3)4(+)). However, CH4(+) gains such maximum stabilization due to T2⊗ (e + t2)-JT distortion. From this novel result and applying the epikernel principle, we propose that the structural evolution of C(CH3)4(+) from Td to C3v minimum energy configuration occurs via JT active vibrations of t2 symmetry, whereas CH4(+) rearranges to the C2v structure through a combination of JT active e and t2 bending vibrations.

Abstract
Mydriatic drops are routinely administered to premature neonates to screen for retinopathy of prematurity. Adverse anticholinergic side effects, particularly convulsions and tachycardia have been reported in the pediatric age group following instillation of mydriatics for diagnostic fundus examination [1, 2]. Caffeine is frequently used for apnea of prematurity. In the neonatal intensive care unit, the combined use of caffeine and mydriatic drops is a common practice. Here we report two cases of atrial arrhythmias after neonatal eye exam that improved with conservative management. Both patients were receiving caffeine at the time of events.

Abstract
An ab initio quantum dynamics study has been performed to explore the structural rearrangement of ground state CH4 (+) in subfemtosecond resolved photodynamics. The method utilizes time-dependent wave-packet propagation on the X˜(2)T2 electronic manifold of the title cation in full dimensionality, including nonadiabatic coupling of the three electronic sheets. Good agreement is obtained with recent experiments [Baker et al., Science 312, 424 (2006)] which use high-order harmonic generation to probe the attosecond proton dynamics. The novel results provide direct theoretical support of the observations while unravelling the underlying details. With the geometrical changes obtained by calculating the expectation values of the nuclear coordinates as a function of time, the structural evolution is predicted to begin through activation of the totally symmetric a1 and doubly degenerate e modes. While the former retains the original Td symmetry of the cation, the Jahn-Teller active e mode conducts it to a D2d structure. At ∼1.85 fs, the intermediate D2d structure is further predicted to rearrange to local C2v minimum geometry via Jahn-Teller active bending vibrations of t2 symmetry.

Abstract
AIM To develop a generic self-management skills scale for use with adolescents diagnosed with a chronic health condition who are aged 12 to 18 years. BACKGROUND There is a lack of methodologically sound scales for healthcare teams to use to measure self-management skills in adolescents with chronic conditions transitioning to adult care. METHODS Adolescents aged 12 to 18 years with a broad range of chronic health conditions, including neurodevelopmental conditions, were recruited from May to August 2013 from nine outpatient clinics at McMaster Children's Hospital (Canada). Thirty-two participated in a cognitive interview, and 337 completed a questionnaire booklet. Interviews were used to develop the TRANSITION-Q. Rasch measurement theory (RMT) analysis was used to identify items that represent the best indicators of self-management skills. Traditional psychometric tests of measurement performance were also conducted. RESULTS The response rate was 92% (32/32 cognitive; 337/371 field test). RMT analysis resulted in a 14-item scale with three response options. The overall fit of the observed data to that expected by the Rasch model was non-significant, providing support that this new scale measured a unidimensional construct. Other tests supported the scale as scientifically sound, e.g. Person Separation Index = 0.82; good item fit statistics; no differential item function by age or gender; low residual correlations between items; Cronbach's alpha = 0.85; test-retest reliability = 0.90; and tests of construct validity that showed, as hypothesized, fewer skills in younger participants and in participants who required assistance to complete the scale. Finally, participants who agreed they are ready to transfer to adult healthcare reported higher TRANSITION-Q scores than did participants who disagreed. CONCLUSIONS The TRANSITION-Q is a short, clinically meaningful and psychometrically sound scale. This generic scale can be used in research and in paediatric and adolescent clinics to help evaluate readiness for transition.

Abstract
Background: Diarrheal diseases are an important cause of mortality and morbidity globally in children under 5 years of age. Objective: To find the prevalence and risk factors of diarrhea among children under 5 years. Materials and Methods: A population-based analytical cross-sectional study was conducted in the urban slums of Bankura, West Bengal on the prevalence of diarrhea and feeding practices, nutrition, and immunization among 152 children under 5 years (69 males and 83 females). Results: Overall prevalence of diarrhea was 22.36%; 21.73% males and 22.89% females were affected with diarrhea. There were 57.69% diarrhea cases in children of 7-12 months age group, followed by 25.71% in those of 13-24 months age group; with increasing age, the prevalence of diarrhea gradually decreased. Diarrhea was noted to be 20.33% in exclusively breastfed children and 31.57% in children who were breastfed for less than 6 months. In bottle-fed children, the frequency of diarrhea was 26.08%. The prevalence of diarrhea was 21.83% in completely immunized children and 30% in partially immunized children. Risk of diarrhea was 19.80% in normal participants and 27.45% in undernourished children. Conclusion: The present study identified a high prevalence of diarrhea in children under the age of 5 years. Findings of the study also revealed the demographic features, feeding practices, immunization practices, and nutritional status as risk factors of diarrhea, which can be tackled by effective education of the community.

Abstract
Introduction: Our present observational study attempted to evaluate the clinical profiles, diagnosis, treatment and follow-up results of 51 pediatric neurocysticercosis patients over a mean duration of five years (from January 2006 to December 2010). Materials and Methods: Diagnosis was mainly based on clinical features, computed tomography (CT)/magnetic resonance imaging scan and exclusion of other causes. Patients with active, transitional cysts and seizure were treated with albendazole for 28 days, steroids and anticonvulsants. Results: A total of 38 patients completed this study. Mean age of the presentation was 8.47 ± 3.19 years 52.6% of the patients were female. Overall patients presented with generalized seizure in 55.3%, focal in 31.6%, headache ± vomiting in 63.2%, focal neurodeficit in 10.5% and combination of symptoms in 60.5% cases. Contrast CT brain showed a solitary lesion in 27 (71.1%) and multiple in the rest. At presentation lesions were transitional in 58.2%, inactive in 20% and mixed in 14.6%. After a mean of 2 years, seizure persisted in 9 (23.7%) and headache in 8 (21.1%) of whom six had normal electroencephalography (EEG) while one each showed focal slowing, generalized slowing and epileptiform discharges. During the follow-up, CT scan brain 44.7% lesions calcified, 31.6% disappeared, 10.5% regressed and the rest persisted. Conclusion: Solitary ring enhancing lesions (transitional stage) involving the parietal lobe was the commonest CT picture at presentation. Generalized tonic-clonic seizure was the most common type of seizure. Number of lesions, persistence of lesion, number of seizures, EEG abnormality at presentation were not found to be prognostically significant (P > 0.05).

Abstract
Pulmonary artery sling (PAS) is a rare congenital vascular anomaly where the left pulmonary artery (LPA) originates from the right pulmonary artery and passes between the trachea and esophagus. Limited literature has been published about PAS in twins. This report demonstrates two different outcomes in mono-mono twins presenting with PAS. Patients with PAS can experience sequelae including wheezing, stridor, atelectasis, or emphysema. Vascular rings occur when the anomalous LPA encircles the airway and esophagus, causing direct compression and respiratory distress. In the case of LPA sling, the sling does not encircle the airway and esophagus but acts as a cradle so the airway which is adjacent to the vessel is not directly compressed. Unfortunately, patients with LPA sling may become severely ill due to airway narrowing even when there is no compression of the adjacent airway. This is the more common presentation in PAS and was seen in Twin A whereas direct airway compression was seen in Twin B. PAS usually presents in patients during their first year of life and high clinical suspicion is important for diagnosis. As this case report demonstrates, presentations and outcomes can be variable in mono-mono twins with LPS and as a result, appropriate investigations should be offered with monitoring of respiratory compromise.
