Abstract
We have designed and synthesized three pyrazole analogs (4, 5a, 5b), pyrazole-based chalcones (6a-6d) and (8a-8h), and N-formyl/acetyl 1,3,5-trisubstituted pyrazoline analogs (7a-7d), (9a-9d). FT-IR, 1H, 13C NMR, and mass spectrometry techniques were used to describe the structures of all the synthesized analogs. The single crystal X-ray method was used to identify the molecular structure of derivatives 4 and 5a. All synthesized analogs were screened by MTT assay on two cancer cell lines, the human lung cancer cell line (A549) and cervical cancer cell line (HeLa). Among all compounds, analog 9d demonstrates significant anticancer activity against HeLa (IC50 = 23.6 μM) and A549 (IC50 = 37.59 μM). The non-interactive interaction of active compound (9d) with Calf thymus DNA (Ct-DNA) has been investigated through various methods, such as UV-vis absorption, emission, cyclic voltammetry and circular dichroism. The DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical has been used to measure the antioxidant capacity of the pyrazoline derivative (9d). The outcomes showed that active analog has significant antioxidant activity. In addition, MD simulation of the EGFR tyrosine kinase protein-ligand complex was performed at a time scale of 100 ns. The MMGBSA data of ligand-protein complex are showed stable interactions up to 100 ns.

Abstract
Entropion is one of the common eyelid marginal malposition and it causes irritation, and ulceration of the cornea that leads to visual loss of a patient. Patient may present with watering and foreign body sensation of the eye initially. Entropion may occur in the upper or lower eyelid. Involutional entropion is common and affected the lower eyelid. There are various non-surgical and surgical options to correct the entropion. Non-surgical procedures include taping the lower eyelid which relieves the entropion temporarily, botulinum toxin type-A injection into lower eyelid may temporarily relief the discomfort from entropion up to 6 months. This study was carried out to assess the outcome of the everting sutures for the correction of lower eyelid involutional entropion and to describe the cost effective of the procedure. A nonrandomized, non control group quasi experimental study was conducted in a Tertiary Eye Hospital, in Gopalganj, Bangladesh from January 2016 to December 2019. A less invasive everting sutures technique was applied for the correction of involutional entropion of eyelid. Follow up was maintained at regular intervals and we assess the outcome of the surgical techniques. We evaluated 33 eyes of 31 patients. The success rate was 87.88%. Recurrences were observed in 5(15.15%) eyelids in the 18 months follow up times. The time of the procedure was only 10 minutes, and the cost of the procedure was cheaper. Everting sutures was minimal invasive, non-incision, cost effective procedure for the correction of involutional entropion.

Abstract
Early Infant Diagnosis of HIV infection services are crucial for managing the perinatally acquired HIV infection. Assessing the performance of the EID services and its underlying determinants is important for the National AIDS Control Program, India. The objectives of this study were to find out access to HIV testing, the timeliness of the testing cascade, and the proportion of HIV exposed infants who are followed up to 18 months for a definitive diagnosis of HIV. The study design was a mixed method. A total of 11 states accounting for 80% of HIV-positive pregnant women were selected. Program records from a total of 62 Integrated counselling and testing centres (ICTCs) served as the source of information. The qualitative component included interviews of program managers at the state and district level, service providers at the ICTC level, and caregivers of HIV exposed infants. In the sampled 62 ICTCs, 78% of the HIV exposed infants had at least one HIV test. Of the infants who had HIV tests, 50% had at first sample collected by 8 weeks of age. The median turnaround time from sample collection to DNA PCR testing was 36 (IQR 19-70) days and that to next sample collection in case of detection of virus in the first sample was 66 (IQR 55-116) days. At 18 months of age, 544 (62%) HIV exposed infants were retained in the EID testing cascade. A total of 30 infants were diagnosed with HIV at a median age of 421 (IQR 149-650) days. More than three fourth of the HIV exposed infants had access to early infant diagnosis (EID) services. Both demand and supply-side factors contribute to access, timeliness and retention and there is a need to address these factors.

Abstract
We have synthesized the pyrazole-bearing Schiff base derivatives (5a-5e) and (6a-6h) then the structural confirmation was supported by various spectral analyses. The antibacterial activity of all analogs was screened against bacterial strains Staphylococcus aureus, Bacillus subtilis, Enterococcus faecalis, Escherichia coli, Klebsiella pneumonieae and Pseudomonas aeruginosa. In comparison to the reference drug ciprofloxacin, the lead analogs 5c and 6c showed potent activity, with MIC values of 64 µg/mL against E. coli and B. subtilis. Compound 5c showed a moderate effect with a MIC value of 128 µg/mL against B. subtilis, P. aeruginosa and K. pneumonieae, while compound 6c was against E. coli and P. aeruginosa. Furthermore, the compounds 5c and 6c displayed groove binding mode towards CT-DNA by absorption, emission, competitive fluorescence studies using EtBr, CD and time-resolved fluorescence studies. Thermodynamic parameters of analogs 5c and 6c with CT-DNA were also calculated at 298, 303 and 308K temperatures by UV-visible spectroscopy. The molecular docking studies give the docking score for all compounds with PDB codes: 1BNA and 2XCT. The MD simulation study of analogs 5c and 6c was also carried out. The pharmacokinetic and ADME properties were calculated for all of the synthesized analogs (5a-5e) and (6a-6h).Communicated by Ramaswamy H. Sarma.

Abstract
PURPOSE To understand the benefits of COVID-19 vaccination (Covishield, Covaxin) on clinical features and outcome of COVID-19 during the third wave in India. MATERIALS AND METHODS The primary study aim was to describe the clinical profile and outcome of COVID-19 regarding their vaccination and to identify risk factors for disease progression in vaccinated patients. This was a prospective observational multicentric study of COVID-19 attended by Infectious Disease physicians during January 15, 2022 to February 15, 2022. Adult patients with positive RT-PCR or rapid antigen test for COVID-19 were enrolled. Patient received treatment as per local institutional protocol. Chi square test for categorical and Mann Whitney test for continuous variables were applied for the analysis. Logistic regression was used to calculate adjusted odds ratios. RESULTS A total of 788 patients were included in analysis out of 883 enrolled patients from 13 centers across Gujarat. By the end of two weeks' follow up, 22 patients (2.8%) had expired. The Median age of subjects was 54 years, with a (55.8%) male. 90% of the subjects were vaccinated, majority (77%) of them had received 2 doses of vaccine with Covishield (659, 93%). Mortality among the non-vaccinated was significantly (11.4%) higher than vaccinated (1.8%). Logistic regression analysis showed numbers of comorbidities (p = 0.027), baseline higher WBC count (p = 0.02), higher NLR (p = 0.016), and Ct value (p = 0.046) were associated with mortality while vaccination was associated with survival (p = 0.001). The factors associated with mortality among vaccinated were age, comorbidities, baseline higher WBC, NLR, and CRP. CONCLUSIONS Omicron variant was associated with mild symptoms. Clinical and laboratory risk factors for getting severe disease with Omicron variant were the same with previous SARS CoV-2 strain. Two doses of vaccine protect people against severe disease and death. Age, comorbidities, baseline leucocytosis, high NLR, elevated CRP are the risk factors for poor outcome in vaccinated patients.

Abstract
To discover anticancer drugs with novel structures and expand our research scope, pyrazoline derivatives (3a-3l) were designed and synthesized through cyclization of chalcones with thiosemicarbazide/semicarbazide in CH3COOH as a solvent. All newly synthesized pyrazoline derivatives were fully characterized using several spectroscopic experiments such as 1H, 13C NMR, FT-IR spectroscopy, and mass analysis. By HPLC, the purity of all analogs was found above 95% and both lead compounds (3a and 3h) were also validated by HRMS. Anticancer activity of synthesized pyrazoline derivatives (3a-3l) was investigated by the MTT assay against the human lung cancer cell (A549), human cervical cancer cell (HeLa), and human primary normal lung cells (HFL-1). Staurosporine (STS) was used as a standard drug. The anticancer results showed that two potent analogs 3a and 3h exhibit excellent activity against A549 (IC50 = 13.49 ± 0.17 and 22.54 ± 0.25 μM) and HeLa cells (IC50 = 17.52 ± 0.09 and 24.14 ± 0.86 μM) and low toxicity against the HFL-1 (IC50 = 114.50 ± 0.01 and 173.20 ± 10 μM). The flow cytometry was further used to confirm the anticancer activity of potent derivatives against the A549 cancer cell line. DNA binding interaction of anticancer agents 3a and 3h with Ct-DNA has been carried out by absorption, fluorescence, EtBr (dye displacement assay), circular dichroism, cyclic voltammetry and time-resolved fluorescence, which showed noncovalent binding mode of interaction. Anticancer activity of both lead compounds (3a and 3h) may be attributed to DNA binding. The evaluation of the antioxidant potential of pyrazoline analogs 3a and 3h by 2,2-diphenyl-1-picrylhydrazyl free radical showed promising antioxidant activity with IC50 values of 0.132 ± 0.012 and 0.215 ± 0.025 μg/mL, respectively. In silico molecular docking of pyrazoline derivatives was also performed using autodock vina software against the DNA hexamer with PDB ID: 1Z3F and ADMET properties to explore their best hits.

Abstract
The thalidomide-DNA interactions have been investigated in detail by numerous biophysical techniques such as UV-vis, dye displacement assay, viscosity, cyclic voltammetry, circular dichroism, molecular docking, molecular dynamic simulation, FT-IR and 1H NMR spectroscopy. CD spectroscopy, thermal denaturation and viscosity measurement explained that thalidomide is groove binder. Molecular docking analysis highlighted that thalidomide binds trough minor groove of calf thymus DNA which also confirmed from dye displacement experiment. To our knowledge, this is the first instance thalidomide was shown to binds with calf thymus DNA. Molecular dynamic simulation indicated that the thalidomide-DNA system was stabilized by electrostatic attraction as the main interaction and mode of binding is minor groove. Our study provides a better understanding to the DNA-thalidomide binding affinity and it mechanism. Overall, all these in formations can be used for further understanding the pharmacological effects of thalidomide.

Abstract
An oxadiazole derivative 2 was prepared by condensation reaction through cyclization of semicarbazone in the presence of bromine and the structural confirmation was supported by 1 H and 13 C NMR, FT-IR spectroscopy, and LC-MS spectrometry. Its sensing ability was examined towards Ni2+ ion with binding constant 1.04 x 105 over the other suitable metal cations (Ca2+ , Co2+ , Cr3+ , Ag+ , Pb2+ , Fe3+ , Mg2+ , and K+ ) by UV-visible and fluorescence spectroscopic studies and the minimum concentration of Ni2+ ion with LOD was found to be 9.4μM. Job's plot method gives the binding stoichiometry ratio of Ni2+ ion vs oxadiazole derivative 2 to be 2:1. Furthermore, the intercalative binding mode of oxadiazole derivative 2 with Calf Thymus DNA was supported by UV-Vis, fluorescence, viscosity, cyclic voltammetry, time-resolved fluorescence, and circular dichroism measurements. The molecular docking result gives the binding score for oxadiazole derivative 2 to be -6.5 kcal/mol, which further confirms the intercalative interaction. In addition, the anti-fungal activity of oxadiazole derivative 2 was also screened against fungal strains (C. albicans, C. glabrata, and C. tropicalis) by broth dilution and disc diffusion method. In the antioxidant studies, the oxadiazole derivative 2 showed potential scavenging activity against DPPH and H2 O2 free radicals.

Abstract
Background Risk factors for the development of severe COVID-19 disease and death have been widely reported across several studies. Knowledge about the determinants of severe disease and mortality in the Indian context can guide early clinical management. Methods We conducted a hospital-based case control study across nine sites in India to identify the determinants of severe and critical COVID-19 disease. Findings We identified age above 60 years, duration before admission >5 days, chronic kidney disease, leucocytosis, prothrombin time > 14 sec, serum ferritin >250 ng/mL, d-dimer >0.5 ng/mL, pro-calcitonin >0.15 μg/L, fibrin degradation products >5 μg/mL, C-reactive protein >5 mg/L, lactate dehydrogenase >150 U/L, interleukin-6 >25 pg/mL, NLR ≥3, and deranged liver function, renal function and serum electrolytes as significant factors associated with severe COVID-19 disease. Interpretation We have identified a set of parameters that can help in characterising severe COVID-19 cases in India. These parameters are part of routinely available investigations within Indian hospital settings, both public and private. Study findings have the potential to inform clinical management protocols and identify patients at high risk of severe outcomes at an early stage.

Abstract
N-formyl pyrazoline derivatives (3a-3l) were designed and synthesized via Michael addition reaction through cyclization of chalcones with hydrazine hydrate in presence of formic acid. The structural elucidation of N-formyl pyrazoline derivatives was carried out by various spectroscopic techniques such as 1H, 13C NMR, FT-IR, UV-visible spectroscopy, mass spectrometry and elemental analysis. Anticancer activity of the pyrazoline derivatives (3a-3l) was evaluated against human lung cancer (A549), fibrosarcoma cell lines (HT1080) and human primary normal lung cells (HFL-1) by MTT assay. The results of anticancer activity showed that potent analogs 3b and 3d exhibited promising activity against A549 (IC50 = 12.47 ± 1.08 and 14.46 ± 2.76 µM) and HT1080 (IC50 = 11.40 ± 0.66 and 23.74 ± 13.30 µM) but low toxic against the HFL-1 (IC50 = 116.47 ± 43.38 and 152.36 ± 22.18 µM). The anticancer activity of potent derivatives (3b and 3d) against A549 cancer cell line was further confirmed by flow cytometry based approach. DNA binding interactions of the pyrazoline derivatives 3b and 3d have been carried out with calf thymus DNA (Ct-DNA) using absorption, fluorescence and viscosity measurements, circular dichroism and cyclic voltammetry. Antioxidant potential of N-formyl pyrazoline derivatives (3a-3l) has been also estimated through DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical and H2O2. Results revealed that all the compounds exhibited significant antioxidant activity. In silico molecular modelling and ADMET properties of pyrazoline derivatives were also studied using PyRx software against topoisomerase II receptor with PDB ID: 1ZXM to explore their best hits. MD simulation of 3b and 3d was also carried out with topoisomerase II for structure-function correlation in a protein. HuTopoII inhibitory activity of the analogs (3a-3l) was examined by relaxation assay at varying concentrations 100-1000 µM.

Abstract
OBJECTIVES The aim of the current study was to evaluate potential differences in the accuracy of mandibular reconstruction and long-term stability, with respect to different reconstructive procedures. METHODS In total, 42 patients who had undergone primary segmental mandibular resection with immediate alloplastic reconstruction, with either manually pre-bent or patient-specific mandibular reconstruction plates (PSMRP), were included in this study. Mandibular dimensions, in terms of six clinically relevant distances (capitulum [most lateral points], capitulum [most medial points], incisura [most caudal points], mandibular foramina, coronoid process [most cranial points], dorsal tip of the mandible closest to the gonion point) determined from tomographic images, were compared prior to, and after surgery. RESULTS Dimensional alterations were significantly more often found when conventionally bent titanium reconstruction plates were used. These occurred in the area of the coronoid process (p = 0.014). Plate fractures were significantly (p = 0.022) more often found within the manually pre-bent group than within the PSMRP group (17%/0%). CONCLUSION The results suggest that the use of PSMRP may prevent rotation of the proximal mandibular segment, thus avoiding functional impairment. In addition, the use of PSMRP may potentially enhance the long-term stability of alloplastic reconstructions.

Abstract
COVID 19 pandemic is a global health emergency which every country is grappling with since beginning of this year. Countries have their own strategies to cope with the cases and there have been no universal guidelines or recommendations for same. We commend the Hon. Prime Minister for taking pre-emptive timely measures to contain the pandemic at very beginning of infection in India as sustaining containment measures. Even the World Health Organisation (WHO) has acknowledged India’s efforts.
According to experts for effective herd immunity about 60% of population needs to be infected, after which the infection will slow down and cases will continue to occur at low levels. For that we need good data coming from the system and government shall ensure that good data is provided for monitoring and surveillance.
If all the susceptible population is exposed (without any restrictions) then we have an exponential rise in cases and our health system will be overwhelmed probably resulting in large number of deaths. Great Britain went ahead with strategy of developing herd immunity in its population and safeguarding the elderly but after projections from Imperial College COVID 19 team, reversed their strategy to social distancing and saving lives as their health system will be overwhelmed.
COVID 19 is a mild disease for people in the younger age group while in people above the age of 60 years, the mortality is high. So staggered exposure of younger population to infection while safeguarding the elderly population at home will prevent the surge of cases and facilitate gradual development of immunity in population.
Government should also focus on developing a robust health care system for screening and management of cases coupled with gradual relaxation of restriction so that health system is not overwhelmed with management of COVID 19.

Abstract
Fifteen million farmers in India engaged in Maize cultivation. India would require 45 MMT of Maize by 2022. But, only 15% of cultivated area of maize is under irrigation and water shortage has been a challenge for sustainability of maize production. Water deficit stress (WDS) during pre-flowering and grain filling stages massively affects the plant performance due to imprecise traits function. Thus, the effect of WDS on non-drought tolerant (NDT) and drought tolerant (DT) maize lines were investigated. WDS increased the flowering days, days to maturity, anthesis silk interval, decreased the leaf number, abnormal expression of secondary stress responsive traits, loss of normal root architecture which overall lead to a reduction in GY/ha. WDS at flowering and grain filling stage leads to significant yield penalty especially in NDT lines than DT lines. The yield penalty was ranged from 34.28 to 66.15% in NDT and 38.48 to 55.95% in DT lines due to WDS. Using multiple statistics, traits which improve WDS tolerance in maize were identified viz; number of leaves, number of stomata on lower surface of leaf, leaf angle at ear forming node internodal length between 3rd and 4th leaf from top, flag leaf length, flag leaf width, ear per plants, leaf senescence, pollen stainability, root fresh weight and root length. These traits would help in trait specific breeding in maize for WDS tolerance.

Abstract
BACKGROUND AND PURPOSE Deep brain stimulation is a well-established treatment for generalized dystonia, but outcomes remain variable. Establishment of an imaging marker to guide device targeting and programming could possibly impact the efficacy of deep brain stimulation in dystonia, particularly in the absence of acute clinical markers to indicate benefit. We hypothesize that the stimulation-based functional and structural connectivity using resting-state fMRI and DTI can predict therapeutic outcomes in patients with generalized dystonia and deep brain stimulation. MATERIALS AND METHODS We performed a retrospective analysis of 39 patients with inherited or idiopathic-isolated generalized dystonia who underwent bilateral globus pallidus internus deep brain stimulation. After electrode localization, the volumes of tissue activated were modeled and used as seed regions for functional and structural connectivity measures using a normative data base. Resulting connectivity maps were correlated with postoperative improvement in the Unified Dystonia Rating Scale score. RESULTS Structural connectivity between the volumes of tissue activated and the primary sensorimotor cortex was correlated with Unified Dystonia Rating Scale improvement, while more anterior prefrontal connectivity was inversely correlated with Unified Dystonia Rating Scale improvement. Functional connectivity between the volumes of tissue activated and primary sensorimotor regions, motor thalamus, and cerebellum was most correlated with Unified Dystonia Rating Scale improvement; however, an inverse correlation with Unified Dystonia Rating Scale improvement was seen in the supplemental motor area and premotor cortex. CONCLUSIONS Functional and structural connectivity with multiple nodes of the motor network is associated with motor improvement in patients with generalized dystonia undergoing deep brain stimulation. Results from this study may serve as a basis for future development of clinical markers to guide deep brain stimulation targeting and programming in dystonia.

Abstract
Background: Major illness requiring hospitalization in poor family makes the family poorer with further tragic outcomes. In that view, Rashtriya Swasthya Bima Yojna (RSBY) by GOI and Mukhyamantri Amrutam (MA) Yojna by Gujarat Government were launched for Below Poverty Line families. Aims & Objectives: To assess knowledge and utilization regarding these two schemes amongst the registered families. Material & Methods: A community-based survey was carried out in a block of Gandhinagar using 30 clusters sampling. Sample size was calculated taking RSBY utilization rate 2.0%. Results: 98.4% had RSBY card & 83.7% had MA card. Common reasons for not having card were either “card not issued/people did not go to collect card” or “were unaware about the schemes/ card”. Only 1.5% families had valid RSBY cards. Knowledge regarding both the schemes (when & where to use, benefit amount etc.) was very poor (20- 25%). RSBY & MA utilization among valid card holders for last 1 year was 1.2% & 0.2% per enrolled member respectively in last 1 year. In both RSBY & MA, 30 – 40% beneficiaries had out of pocket expenditure, mainly towards transport & food. Few had towards medicines and/or investigations. However, most were satisfied with the services. Conclusion: Looking to the poor knowledge, it is important to carry out IEC activities to make people aware about the schemes which will help increase the utilization.

Abstract
BACKGROUND There is no clear consensus about how best to prevent post-dural puncture headache (PDPH) following an accidental dural puncture in parturients. Our primary objective was to investigate whether the insertion of an intrathecal catheter following accidental dural puncture reduces the incidence of PDPH and therapeutic epidural blood patch. METHODS Anaesthetic records from January 2009 to December 2015 were reviewed retrospectively and parturients who had an accidental dural puncture and/or PDPH were identified. Data from those with a recognised dural puncture in whom an intrathecal catheter was inserted at the time of accidental dural puncture (ITC group) were compared to those without an intrathecal catheter (non-ITC group), as were outcomes of patients with an intrathecal catheter for ≥24 hours compared to <24 hours. RESULTS Of 94 recognised accidental dural punctures, 66 were in the ITC group (37 for ≥24 h) and 28 in the non-ITC group. In the ITC group, 22 (33.3%) required an epidural blood patch in comparison to 19 (67.9%) in the non-ITC group (P <0.01, 95% CI 12.5 to 52.0). In the ITC group, 62 (93.9%) developed PDPH in comparison to 28 (100%) in the non-ITC group (P=0.186, 95% CI -6.55 to 14.57). Intrathecal catheter insertion for ≥24 h obviated the need for an epidural blood patch in 28 (75.7%) parturients, compared to 13 (59.1%) if <24 h (P=0.184, 95% CI -7.08 to 39.72). CONCLUSION Inserting an intrathecal catheter after a recognised accidental dural puncture significantly reduced the need for an epidural blood patch.

Abstract
Background Teeth restored with direct composite resin are constantly exposed to specific challenges of the oral cavity. These challenges can modify the material properties and, when associated with daily brushing, eventually change its surface roughness, allowing bacterial growth and retention of extrinsic pigments. Dentifrices plays an important role in dental wear (abrasion) and over time, can also cause an increase in the surface roughness of restorative materials. Objective To assess the effect of dentifrices on the longevity of direct nanofilled composite resins restorations as far as wear and roughness is concerned. Method Class V cavity were prepared on 90 extracted human teeth and restored with Filtek Z350 composite. Teeth were randomly divided into 6 experimental groups of 15 each labelled as Group-1 (Colgate Dental cream) Group-2 (Colgate Active Salt toothpaste), Group-3 (Pepsodent Regular toothpaste), Group-4 (Dabur red toothpaste), Group-5 (Dabur Lal tooth powder) and Group-6 Control (water). The samples were fixed on tooth brushing machine and subjected to mechanical tooth brushing using various dentifrices according to respective groups in 3 phases and reading of surface roughness (Ra) was recorded. Result Surface roughness (Ra) had increased in following order: Group 6 < Group 3 < Group 2 < Group 1 < Group 4 < Group 5. All the tooth pastes were compared, their behaviour was found to be similar as there was no statistically significant difference amongst them. Though all of them were inferior to control group and the difference was statistically significant. Whereas the only tooth powder Dabur lal tooth powder gave the maximum roughness when compared with the other tooth pastes and the difference was statistically significant. Conclusion With increase in time of brushing there was increase in surface roughness in all the 5 dentifrices among them Ra was maximum for Dabur lal tooth powder.

Abstract
INTRODUCTION Cognitive functions have significant influence on psycho-social and general wellbeing. The quality, content and processing of negative thoughts initiate depressive symptoms; i.e. low mood, decreased self-worth and diminished interest in pleasurable activities. The study assessed the automatic thoughts of patients having depressive illness and evaluated and compared the changes after therapy; i.e. Psychotherapy and pharmacotherapy. METHODS Diagnosed cases of depressive illness (n=135), according to ICD-10 and study criteria, attending the out-patient clinic of Department of Psychiatry and Mental Health, Tribhuvan University Teaching Hospital, were included. Beck Depression Inventory was used to screen level of depressive symptoms. Automatic thoughts were assessed by the Automatic Thought Questionnaire-Revised before initiating therapy and after completion of therapy for comparison. Depressive patients received either of the three treatment procedures after randomization of the study sample into three different treatment groups; i.e. Cognitive behavior therapy, pharmacotherapy or combined therapy receiving both cognitive behavior therapy and pharmacotherapy. RESULTS Among the total 135 patients, 53 (39.3%) had moderate, 47 (34.8%) had severe depressive and 35 (25.9%) had mild depressive symptoms before therapeutic interventions. Negative automatic thoughts were significantly present in depressed patients and reduced after all three interventions. Negative automatic thoughts of hopelessness, anxiety and inability coping were significantly reduced after therapy. CONCLUSIONS Automatic negative thoughts were significantly correlated with depressive disorder. Combined therapy CBT with pharmacotherapy or CBT alone was found to be more effective in modifying automatic negative thoughts than pharmacotherapy alone, ultimately reducing depressive symptoms to a significant degree.

Abstract
Background: Presence of a person with mental disorder in family is often associated with some objective and subjective burden on family members, especially those who have a caregiving role. The present study aimed to assess the levels of caregiving burden among family members of people with mental illness.Method: This is a descriptive cross-sectional study in a sample of 56 family caregivers of people with mental illness. Sample was selected using purposive sampling method and their caregiving experience was assessed by using Burden Assessment Schedule.Result: Among the 56 caregivers, 48.2 % had moderate level of burden and 32.1% had severe level of burden. Highly significant difference was observed in the distribution of burden according to level of burden but no significant gender difference was found in the distribution of burden in total and in different domains of BAS. Highly significant burden was found among married and spouse caregivers.Conclusion: As moderate to severe level of caregiving burden was reported by the family caregivers, it is recommended that family intervention should focus on strengthening coping behaviors and social support system to manage caregiving stress.

Abstract
We report an HIV-positive renal transplant recipient with delayed graft function who was converted from tacrolimus to belatacept in an attempt to improve renal function. The patient had kidney biopsies at 4 and 8 weeks posttransplant that revealed acute tubular necrosis and mild fibrosis. After 14 weeks of delayed function, belatacept was initiated and tacrolimus was weaned off. Shortly after discontinuing tacrolimus, renal function began to improve. The patient was able to discontinue dialysis 21 weeks posttransplant. HIV viral load was undetectable at last follow-up. To our knowledge, this is the first report of belatacept use in a patient with HIV.

Abstract
A bacterial strain identified as Pseudomonas sp. RPT 52, was isolated from an agricultural field by soil enrichment technique. The bacterial strain was able to metabolize three different chlorinated pesticides; imidacloprid, endosulfan and coragen (belonging to neonicotinoid, organochlorine and anthranillic diamide categories, respectively). RPT 52 was able to degrade 46.5%, 96.6%, 92.7% and 80.16% of 0.5 mM of imidacloprid, endosulfan α, endosulfan β and coragen, respectively, in minimal medium over a period of 40 h, when provided as sole source of carbon and energy. Degradation kinetics showed that imidacloprid, endosulfan α and endosulfan β followed first order kinetics whereas coragen followed zero order kinetics. Toxicity studies show reduction in toxicity of the parent compound when degraded by RPT 52. Laboratory scale, soil microcosm studies showed that strain RPT 52 is a suitable candidate for bioremediation of endosulfan and coragen contaminated sites. Thus, RPT 52 holds potential for toxicity reduction in the affected environment.

Abstract
INTRODUCTION Alcohol dependence is a chronic disorder, accompanied by neuropsychological deficits. Patients with alcohol dependence were evaluated to identify the cognitive dysfunctions. METHODS The study followed descriptive design and recruited participants (N=62) from inpatient services of the Department of Psychiatry and Mental Health by convenient sampling. Participants were evaluated with the Severity of Alcohol Dependence Questionnaire, Frontal Assessment Battery and PGI Memory Scale for the severity of alcohol dependence, executive impairments and memory dysfunctions respectively once they had completed alcohol detoxification. RESULTS Total duration of alcohol consumption was 13.93 ± 8.74 years, period of dependence was 2.97 ± 2.23 years and 56.5% had moderate level of dependence. 33.9% of the participants had executive impairments particularly in conceptualization, programming and mental flexibility. 38% of variance in executive dysfunction was explained by illness variables, where period of alcohol dependence and education were significant predictors. 54.8% had significant memory dysfunction particularly in visual retention, remote memory, verbal retention of dissimilar pairs and delayed recall. Memory dysfunction differed significantly among the age groups (F=10.22, p<0.01) and age was a significant predictor (β=.542, p<0.001). 19% variance in memory dysfunction was explained by illness variables, where duration of alcohol consumption was a significant predictor (β = .485, p<0.01). CONCLUSION Findings indicate that cognitive dysfunctions are prevalent among patients with alcohol dependence. Hence, routine neuropsychological assessment is of particular importance for early detection and remediation of underlying deficits, which completes the treatment of alcohol dependence.

Abstract
Infection with Strongyloides stercoralis is typically asymptomatic in immunocompetent hosts, despite chronic infection. In contrast, immunocompromised hosts such as solid organ transplant recipients are at risk for hyperinfection syndrome and/or disseminated disease, frequently resulting in fatal outcomes. Infection in these recipients may result from reactivation of latent infection or infection through transmission from an infected donor. We describe the Centers for Disease Control and Prevention's experience with seven clusters of donor-derived infection from 2009 to 2013. Six of the seven (86%) donors were born in Latin America; donor screening was not performed prior to organ transplantation in any of these investigations. Eleven of the 20 (55%) organ recipients were symptomatic, two of whom died from complications of strongyloidiasis. We also describe the New York Organ Donor Network (NYODN) experience with targeted donor screening from 2010 to 2013. Of the 233 consented potential donors tested, 10 tested positive for Strongyloides antibody; and 18 organs were transplanted. The majority (86%) of the donors were born in Central or South America. Fourteen recipients received prophylaxis after transplantation; no recipients developed strongyloidiasis. The NYODN experience provides evidence that when targeted donor screening is performed prior to transplantation, donor-derived infection can be averted in recipients.

Abstract
The nucleating activity of the Arp2/3 complex promotes the assembly of branched actin filaments that drive plasma membrane protrusion in migrating cells. Arp2/3 complex binding to nucleation-promoting factors of the WASP and WAVE families was previously thought to be sufficient to increase nucleating activity. However, phosphorylation of the Arp2 subunit was recently shown to be necessary for Arp2/3 complex activity. We show in mammary carcinoma cells that mutant Arp2 lacking phosphorylation assembled with endogenous subunits and dominantly suppressed actin filament assembly and membrane protrusion. We also report that Nck-interacting kinase (NIK), a MAP4K4, binds and directly phosphorylates the Arp2 subunit, which increases the nucleating activity of the Arp2/3 complex. In cells, NIK kinase activity was necessary for increased Arp2 phosphorylation and plasma membrane protrusion in response to epidermal growth factor. NIK is the first kinase shown to phosphorylate and increase the activity of the Arp2/3 complex, and our findings suggest that it integrates growth factor regulation of actin filament dynamics.

Abstract
PURPOSE To report two cases of microbial keratitis with subsequent corneal perforation immediately following corneal collagen crosslinking (CXL). METHODS Retrospective case note review. RESULTS First case was a 19 year old female presented with staphylococcal corneal abscess 3 days post CXL procedure. Corneal perforation occurred during hospital admission and was successfully treated with corneal gluing. Microbial keratitis eventually resolved, with both topical and systemic antibiotics therapy, resulting in a vascularized corneal scar. Second case was an 18 year old male whom developed Methicillin Resistant Staphylococcus aureus (MRSA) corneal abscess 5 days after CXL procedure for progressive keratoconus. Corneal perforation occurred 48 h after presentation and patient underwent uneventful corneal gluing. Although infective keratitis was successfully treated with topical therapy, patient had visual outcome of count fingers due to scarring. CONCLUSIONS CXL has been widely used in the treatment of corneal ectatic conditions and complications, such as infective keratitis, are uncommon post procedure. We present two cases of severe microbial keratitis with subsequent corneal perforation within 7 days of CXL. The exact mechanism for the accelerated keratolysis process is unclear. Nonetheless, patients should be well-informed of such potentially devastating complication.

Abstract
Donor-derived bacterial infection is a recognized complication of solid organ transplantation (SOT). The present report describes the clinical details and successful outcome in a liver transplant recipient despite transmission of methicillin-resistant Staphylococcus aureus (MRSA) from a deceased donor with MRSA endocarditis and bacteremia. We further describe whole genome sequencing (WGS) and complete de novo assembly of the donor and recipient MRSA isolate genomes, which confirms that both isolates are genetically 100% identical. We propose that similar application of WGS techniques to future investigations of donor bacterial transmission would strengthen the definition of proven bacterial transmission in SOT, particularly in the presence of highly clonal bacteria such as MRSA. WGS will further improve our understanding of the epidemiology of bacterial transmission in SOT and the risk of adverse patient outcomes when it occurs.

Abstract
BACKGROUND Multiple choice questions (MCQs) are frequently used to assess students in different educational streams for their objectivity and wide reach of coverage in less time. However, the MCQs to be used must be of quality which depends upon its difficulty index (DIF I), discrimination index (DI) and distracter efficiency (DE). OBJECTIVE To evaluate MCQs or items and develop a pool of valid items by assessing with DIF I, DI and DE and also to revise/ store or discard items based on obtained results. SETTINGS Study was conducted in a medical school of Ahmedabad. MATERIALS AND METHODS An internal examination in Community Medicine was conducted after 40 hours teaching during 1(st) MBBS which was attended by 148 out of 150 students. Total 50 MCQs or items and 150 distractors were analyzed. STATISTICAL ANALYSIS Data was entered and analyzed in MS Excel 2007 and simple proportions, mean, standard deviations, coefficient of variation were calculated and unpaired t test was applied. RESULTS Out of 50 items, 24 had "good to excellent" DIF I (31 - 60%) and 15 had "good to excellent" DI (> 0.25). Mean DE was 88.6% considered as ideal/ acceptable and non functional distractors (NFD) were only 11.4%. Mean DI was 0.14. Poor DI (< 0.15) with negative DI in 10 items indicates poor preparedness of students and some issues with framing of at least some of the MCQs. Increased proportion of NFDs (incorrect alternatives selected by < 5% students) in an item decrease DE and makes it easier. There were 15 items with 17 NFDs, while rest items did not have any NFD with mean DE of 100%. CONCLUSION Study emphasizes the selection of quality MCQs which truly assess the knowledge and are able to differentiate the students of different abilities in correct manner.
