'Substantial clinical benefit' and 'substantial clinical worsening' cut-off of Vitiligo Impact Scale (VIS)-22 change scores

Patient-centric outcome measures focus on clinically meaningful change in various aspects of disease, including severity, quality-of-life, and psychological distress. The minimal important change (MIC) is a commonly used threshold of patient-reported outcome measures, representing the smallest difference that is considered significant by the patient and/or physician. However, it has been suggested that MIC is too low a bar for determining treatment success, and alternative thresholds such as substantial clinical benefit (SCB) and patient acceptable symptom state (PASS) may be preferred.

Low serum vitamin D in North Indian multi-drug resistant pulmonary tuberculosis patients: the role of diet and sunlight

Background: Tuberculosis (TB) and malnutrition are major global health problems, with multidrug-resistant (MDR) TB complicating international efforts. The role of vitamin D in susceptibility to and as an adjunctive treatment for TB is being studied extensively, although no study has included MDR-TB patients in context to dietary profile with vitamin D levels and sunlight exposure.Objective: This study aimed to estimate vitamin D serum levels and examine their association with dietary intake of vitamin D and sun exposure in patients with MDR-TB.Methods: North Indian participants were enrolled in three groups: MDR-TB, drug-susceptible pulmonary TB (DS-PTB), and healthy controls. All consenting participants underwent the estimation of macro- and micronutrient intake and sunlight exposure using structured questionnaires. Serum biochemistry, including 25-hydroxyvitamin D and calcium levels, was measured, and the correlation between variables was determined.Results: 747 participants were enrolled. Significant differences among the three groups were found in mean serum 25-hydroxyvitamin D levels, body mass index, macronutrient intake, dietary vitamin D and calcium content, and sun exposure index (SEI). All except sun exposure (SEI was highest in DS-PTB patients) were found to follow the trend: MDR-TB < DS-PTB < healthy controls. The mean serum vitamin D levels of all groups were deficient and correlated positively with dietary intake and SEI.Conclusion: In this study's we found significant association of serum vitamin D concentrations, dietary intake and sunlight exposure in MDR-TB, DS-PTB patients and healthy controls. Dietary intake may be more important than sun exposure in determining serum levels. However, the significance of this finding is uncertain. Further studies are required to confirm the association, direction, and potential for vitamin D supplementation to treat or prevent MDR-TB infection.

Addition of aprepitant improves acute emesis control in children and adolescents receiving induction chemotherapy for acute myeloid leukaemia: a randomised, open-label trial

OBJECTIVES

More than 50% patients develop emesis during induction therapy for acute myeloid leukaemia (AML). The addition of aprepitant for emesis control in children receiving induction for AML have not been explored.

METHODS

A single-institutional randomised, open-label trial (NCT02979548) was conducted where children between 5 and 18 years with the diagnosis of AML being planned for 3+7 induction regimen were included. All study participants received ondansetron (0.15 mg/kg) every 8 hours for 8 days starting 30 min prior to chemotherapy. Children belonging to aprepitant group additionally received aprepitant capsules (15-40 kg=days 1-3, 80 mg; >40 kg=day 1, 125 mg and days 2-3, 80 mg) starting from 1 hour prior to chemotherapy. The proportion of patients with complete response (CR) in chemotherapy induced vomiting (CIV) in acute phase (day 1-8), delayed phase (day 9-13), overall and initial 96 hours were recorded along with severity of vomiting and adverse effects.

RESULTS

Total 78 children were randomised (Aprepitant group: 37 and control group: 41). The proportion of patients with CR in CIV was significantly higher in Aprepitant group in acute phase (p=0.007), overall phase (p=0.007) and in initial 96 hours (p<0.001) but it was not different in delayed phase (p=0.07). The first episode of vomiting was also significantly delayed in aprepitant group (p=0.02). Adverse effect profile was similar in two groups.

CONCLUSION

Aprepitant significantly improves emesis control in children receiving induction therapy for AML, especially in acute phase and should be routinely incorporated as part of antiemetic prophylaxis.

TRIAL REGISTRATION NUMBER

The study was registered at ClinicalTrials.gov (NCT02979548).

Impact of Bundled Intervention on Outcomes of Patients Undergoing Clean Orthopedic Surgeries With Hardware Implants: Small Prospective Randomized Controlled Trial

Background: Prosthesis-related infections (PRIs) and surgical site infections (SSIs) remain one of the most devastating complications among patients undergoing clean orthopedic surgeries. Prevention strategies are critical to reduce infection rates in orthopedic surgeries. The current study aimed to determine the effectiveness of a set of evidence-based practices (bundled intervention) in reducing the incidence of PRIs and SSIs among patients undergoing clean orthopedic surgeries with hardware implants. Patients and Methods: A prospective, interventional randomized controlled trial was conducted for a period of three years. A total of 597 patients were enrolled, and depending on their Staphylococcus aureus carrier status were categorized into carrier group (n = 98) and non-carrier group (n = 499). Only carrier group patients were analyzed for effectiveness of bundled interventions, after being randomly assigned to two subgroups: interventional carrier group (ICG; n = 50) and non-interventional carrier group (NICG; n = 48). Results: Of the 597 patients, 98 (16.4%) were colonized with Staphylococcus aureus, among whom 9 (19.4%) had methicillin resistance. During follow-up, overall infection rate of 1.1% was observed (PRI, 0.3%; SSI, 0.8%). There was no case of PRI/SSI in the ICG. However, in the NICG, one patient developed SSI because of methicillin-resistant Staphylococcus aureus. An endogenous source of infection was demonstrated by pulsed field gel electrophoresis (PFGE). The SSI rate was higher in the NICG (p = 0.002). In the non-carrier group (n = 499), SSIs/PRIs occurred among 1.2% of the patients, because of organisms other than Staphylococcus aureus. Conclusions: Benefit of bundle intervention approach could be demonstrated. Further studies assessing the effectiveness of the individual components of the bundle can inform clinical practice greatly.

Assessment of renal allograft rejection with diffusion tensor imaging

OBJECTIVES

To investigate the value of DTI in differentiation of renal allograft rejection from well-functioning stable allograft, using fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values.

METHODS

In this prospective study, 22 transplant recipients with well-functioning stable allograft (group A) and 20 patients with renal allograft rejection (group B + C) were recruited over a period of 19 months from January 2018 to July 2019. DTI-MRI was performed in all the patients, and FA and ADC values were measured in cortical and medullary regions of the transplanted kidney. On biopsy, graft rejection was classified as acute (group B) (n = 7) and chronic graft rejection (group C) (n = 13) based on the BANNF scoring system. Statistical analysis was performed using STATA v.14.0.

RESULTS

Statistically significant difference between group A and group B + C was noted for cortical (p < 0.001), and medullary (p = 0.003) FA values, and cortical (p = 0.020), and medullary (p = 0.046) ADC values. Cortical(p < 0.001) and Medullary(p = 0.020) FA values showed statistically significant difference between group A and group C, and cortical FA value(p = 0.012) also showed statistically significant difference between group B and group C. AUC (to differentiate between renal allograft rejection and well-functioning stable allograft) for cortical, and medullary FA values and cortical and medullary ADC values were 0.853(p < 0.001), 0.757(p = 0.004), 0.709(p = 0.021) and 0.736(p = 0.009), respectively.

CONCLUSION AND ADVANCES IN KNOWLEDGE

DTI is a promising functional MRI technique for the non-invasive assessment of renal allograft function. Diffusion parameters, such as FA and ADC values, can be useful in the differentiation of renal allograft rejection from well-functioning stable allograft.

Efficacy and Safety of Percutaneous Radiological Gastrostomy (PRG) as a Rescue Measure for Enteral Feeding in Patients with Advanced Head, Neck, and Upper Digestive Malignancies

Background Percutaneous radiologic gastrostomy is an established mode of enteral feeding for nutritional support for patients with dysphagia from upper digestive tract malignancy. Its role as a rescue measure in patients with advanced malignancy, presenting with absolute dysphagia and failure of nasogastric tube insertion has not been well established.

Purpose This study was performed to assess technical success and long-term outcomes of percutaneous radiologic gastrostomy (push type) for nutritional support for patients with absolute dysphagia as a last ditch nonsurgical rescue effort for enteral access.

Materials and Methods This was a prospective observational study of 31 patients who underwent push-type percutaneous radiologic gastrostomy over a period of 2 years (March 2017–March 2019). The study was a part of a larger trial approved by the institutional ethics committee. Patients were followed till the removal of tube, death, or 1 year, whichever was earlier. Gastrostomy tube-related problems and complications were documented. Descriptive summary statistics were employed to analyze the success rate and complications.

Results Thirty-one patients with mean age 56 years (26–78 years) including 18 males and 13 females with head and neck squamous cell cancer and esophageal cancer presenting with absolute dysphagia or significant dysphagia with failed nasogastric or endoscopic enteral access were included. Overall technical success was 93.5% (29/31), achieved in 26/31 patients with just fluoroscopy guidance and 3/5 patients with computed tomography guidance. One major (3.3%) and two minor (6.5%) complications were encountered. Five out of 29 gastrostomy tubes had to be exchanged, after a mean of 44 days (1–128 days) after insertion.

Conclusion Percutaneous radiologic gastrostomy is a safe and effective intervention even as a rescue measure in patients with absolute dysphagia from advanced upper digestive tract malignancies.

Vertebral fractures, trabecular bone score and their determinants in chronic hypoparathyroidism

PURPOSE

Patients with hypoparathyroidism are at risk of vertebral fractures (VFs) despite high bone mineral density (BMD). We investigated this paradox by assessing trabecular bone score (TBS) and hip structural analysis (HSA) in non-surgical chronic hypoparathyroidism (cHypoPT) with and without VFs.

METHODS

152 cHypoPT patients (age 40.2 ± 13.4 years, M: F = 81:71) with a median follow-up of 8 (2-13) years were assessed for BMD, VFs, TBS, and HSA and compared with 152 healthy controls. VFs at T₇-L₄ were assessed by Genant's method. Average serum total calcium and phosphorus during follow-up were assessed.

RESULTS

The lumbar spine and hip BMD were higher by 25.4 and 13.4% in cHypoPT than controls (P < 0.001). Paradoxically, VFs (30.9 vs.7.9%), including multiple (12.5 vs. 2.6%) were higher in cHypoPT (P < 0.001). Though overall average TBS (1.411 ± 0.091) was normal in cHypoPT, 25.4% of the females had subnormal TBS, more in post than pre-menopausal women (52.3 vs. 14%, P = 0.002) and as compared to males (6.1%, P = 0.001). TBS correlated with menopausal status and follow-up serum calcium-phosphorus product. For every gm/cm² rise in BMD, TBS increase was only 0.227 in cHypoPT compared to 0.513 in controls. Frequency of VFs increased with declining TBS (P = 0.004). HSA was comparable between cHypoPT with and without VFs. 23.4% of cHypoPT with VFs had subnormal TBS.

CONCLUSION

31% of cHypoPT patients had VFs. TBS indicated degraded bone microarchitecture in 50% of the post-menopausal cHypoPT women. However, TBS has limitations to detect abnormal bone microarchitecture in cHypoPT as only one-fourth of patients with VFs showed low TBS.

Azithromycin resistance and its molecular characteristics in Neisseria gonorrhoeae isolates from a tertiary care centre in North India

Treatment guidelines for management of uncomplicated gonorrhoeae have been recently modified owing to alarming upsurge in azithromycin resistance. This study investigated the prevalence and genetic determinants of gonococcal azithromycin resistance in India. Four (5.7%) of 70 gonococcal isolates were resistant to azithromycin. Of 16 isolates investigated for molecular mechanisms of resistance, 13 (81.3%) and 6 (37.5%) isolates exhibited mutations in coding and promoter regions of mtrR gene, respectively. However, ermA, ermB and ermC genes or mutations in rrl gene were absent in all isolates. Azithromycin resistance is low in India posing no immediate threat to use of dual-therapy for syndromic management.

Plasmalyte-A Based del Nido Cardioplegia Versus Plain Ringer Based del Nido Cardioplegia: Double-Blind Randomized Trial

Background: In this prospective randomized controlled trial, we compared the standard del Nido cardioplegia solution (SDN) with the modified del Nido cardioplegia solution (MDN) in which the base solution was the plain Ringer solution. Methods: A total of 80 patients aged < 12 years undergoing intracardiac repair of Tetralogy of Fallot were randomized into SDN (n = 39) or MDN (n = 41) groups. The primary outcome was a change in cardiac index (CI). Secondary outcomes were ventricular arrhythmias after the release of aortic-cross clamp, postoperative inotropic score (IS), time to peripheral rewarming, duration of mechanical ventilation, intensive care unit (ICU) length of stay, and hospital length of stay, and electron microscopic differences between the 2 groups. Cardiac Troponin-I, inflammatory markers tumor necrosis factor-α (TNF-α), and interleukin-L (IL-6) were measured. Results: Applying the noninferiority confidence interval approach, the difference between the changes in CI between the 2 groups was -0.093 L/min/m2 (95% CI: -0.46-0.27 L/min/m2) which was within the noninferiority threshold of -0.5 indicating that CI was similar in both SDN and MDN. Ventricular arrhythmias postclamp release (P = .91), IS (P = .09), duration of mechanical ventilation (P = .27), ICU length of stay (P = .50), hospital length of stay (P = .57), IL-6 (P = .19), TNF-α (P = .17), Troponin-I (P = .15), electron microscopy changes (P > .05) were not different between groups. Conclusion: MDN was shown to be noninferior to the SDN cardioplegia in terms of preservation of cardiac index. In addition, other metrics indicative of myocardial protection were similar between groups. In developing nations where SDN is not available or is expensive, MDN cardioplegia is an acceptable alternative.

Differential expression of miRNA in histological subtype of Wilms tumor

INTRODUCTION

Wilms tumor is the most common renal malignancy in children and difficult to differentiate from other paediatric abdominal tumors radiologically, necessitating an invasive procedure for diagnosis. Previous studies have shown the potential role of miRNA as biomarkers for diagnosis, histological subtyping and prognosis. In this study, we are exploring the role of miRNA in the histological subtyping of Wilms tumor in the Indian population.

MATERIALS AND METHODS

A total of 15 cases of Wilms tumor were evaluated for global miRNA expression analysis by microarray. Total RNA was extracted from fresh frozen tumor and miRNA expression analysis was performed using Agilent platform. Unsupervised clustering was done to analyse the data.

RESULTS

Using unpaired student T test, top 10 significantly differentially expressed miRNA were selected which could differentiate among different histological subtypes by unsupervised hierarchical clustering and principal component analysis. The presence of necrosis, heterologous differentiation led to change in miRNA expression profile and led to a distinct cluster formation.

CONCLUSIONS

A panel of 5 miRNAs (miR1, 133b, 299-3p, 499a-5p, 491-3p) could differentiate among different histological subtypes of Wilms tumor, thus avoiding an invasive procedure in children, however, further confirmation using real time PCR analysis will be needed.

Disease stability in segmental and non-segmental vitiligo

Introduction:

Some therapeutic decisions in vitiligo depend on the likelihood of the disease remaining stable and inactive.

Aim:

To determine a period of disease stability in vitiligo following which reactivation was unlikely.

Materials and Methods:

This cross-sectional descriptive study was carried out in 200 patients where a detailed clinical history of the disease activity and stability over the course of vitiligo was recorded.

Results:

There were 167 (83.5%) patients with non-segmental vitiligo and 33 (16.5%) with segmental vitiligo. For every 1-year increase in the duration of the disease, stable and active periods increased by 0.7 and 0.3 years, respectively in non-segmental vitiligo and by 0.9 and 0.1 years in segmental vitiligo (P < 0.01). When segmental vitiligo was stable for at least 2 years, it was five times less likely to re-activate than the disease that was stable for less than 2 years (P = 0.16). However, in non-segmental vitiligo, we found no association between the duration of stability and risk of reactivation.

Conclusions:

Segmental vitiligo usually becomes inactive after the disease has been stable for 2 years. Non-segmental vitiligo is prone to reactivation even after prolonged periods of stability.

Bone mass in newborns and its predictors

OBJECTIVE

Optimal bone mass (a function of foetal programming and adequate intrauterine bone mineral accrual) is essential for prevention of osteoporosis. The present study was planned with the objectives to describe newborn bone mass (NBBM) and study the associated factors.

DESIGN

Observational study Patients: Singleton pregnant women ≤16 weeks gestation.

MEASUREMENTS

Maternal factors and antenatal events: Dietary assessment (3 days-24-h diet recalls at ≤16 and 32-34 weeks), fetal femoral volume (FFV) assessment at 19 and 34 weeks, serum 25 hydroxyvitamin D (S.25OHD) and placental weight. Newborn anthropometric parameters, cord S.25OHD & IGF-1 level and NBBM by DXA (whole-body bone mineral content (BMC), bone mineral density (BMD) and bone area).

RESULTS

Total 224 subjects were studied: 198 full-term and 26 preterm. The mean BMC, BMD and bone area for term newborns was 46.5 g (95% confidence interval [CI]: 45.35-47.66), 0.209 g/cm² (95% CI: 0.206-0.212) and 221.6 cm² (95% CI: 218.52-224.62), respectively. The mean placental weight was 403.2 ± 75.01 g (n = 72) while FFV was 0.71 ± 0.28 ml (19 weeks; n = 59) and 4.4 ± 1.17 ml (34 weeks; n = 33). Factors significantly associated with NBBM -gestational age at delivery, gestational weight gain, FFV at 19 weeks, placental weight, third-trimester maternal serum albumin and newborn anthropometric parameters (univariable analysis) and newborn birth weight, placental weight and FFV at 19 weeks (multivariable analysis).

CONCLUSION

This study described NBBM among term newborns and birth weight, second-trimester FFV and placental weight were the associated factors.

N-terminal pro-brain natriuretic peptide is an independent predictor of mortality in patients with sepsis

This study aims to evaluate the role of cardiac enzymes N-terminal pro-brain natriuretic peptide (NT-proBNP) and cardiac troponin-I (CTnI) as predictors of outcomes in patients with sepsis.78 cases with a diagnosis of sepsis were enrolled over a 2-year period. Baseline demographic, Acute Physiology and Chronic Health Evaluation-II (APACHE-II), Simplified Acute Physiology Score-II (SAPS-II), hematologic and biochemical parameters were noted. Serum NT-proBNP and CTnI were evaluated at 24 and 72 hours of admission along with echocardiography. Patients were prospectively followed up until death or discharge.Mean APACHE-II score was 19.8±9.6 and SAPS-II was 44.8±17.2. Survival rate in the study was 47.5% (36 of 78 patients). NT-proBNP was significantly higher in non-survivors with values over 4300 pg/mL at 24 hours and 5229 pg/mL at 72 hours associated with poor outcomes (p<0.05). CTnI was higher among non-survivors than in survivors, but the difference was not significant. APACHE-II score combined with NT-proBNP predicted a poor outcome in 51.2% cases compared with 14.6% cases with APACHE-II alone (p<0.05), while SAPS-II combined with NT-proBNP predicted a poor outcome in 53.6% cases as compared with 9.6% cases with SAPS-II alone (p<0.05). SAPS-II greater than 45 and NT-proBNP values at 72 hours were independent predictors of mortality in patients with sepsis.NT-proBNP is an independent predictor of mortality in patients with sepsis and its combination with APACHE-II and SAPS-II improves the predictive values of the scoring systems.

Efficacy of NB-UVB in Progressive Versus Non-Progressive Non-Segmental Vitiligo: A Prospective Comparative Study

Introduction:

Narrow-band (NB) ultraviolet B (UVB) phototherapy has been shown to halt disease progression in vitiligo, but whether there is any difference in the response to NB-UVB seen in patients with progressive vitiligo versus non-progressive vitiligo has not been evaluated.

Objectives:

To evaluate the effect of NB-UVB on progressive versus non-progressive non-segmental vitiligo.

Study Design:

Prospective observational comparative study.

Duration:

April 2016-November 2017.

Methods:

Adult patients having non-segmental vitiligo involving 2-50% body surface area were divided into two subsets; patients developing >5 lesions in the last 1 month or >15 lesions in the last 3 months (progressive vitiligo, Group I) and patients with static disease for the last 6 months (non-progressive vitiligo, Group II). Both groups were treated with NB-UVB for 6 months (26 weeks) cumulatively and its efficacy in halting disease progression, re-pigmentation, side effects and psychosocial impact were evaluated.

Results:

Nineteen out of 24 patients with progressive vitiligo had arrest of disease progression. Rest five patients developed lesions at a slower pace. Group II had earlier onset of re-pigmentation, while Group I had more NB-UVB fluence (34.73 J/cm² vs 25.2 J/cm², P value = 0.034), more time for the fluence to be fixed (P value = 0.001) and more pruritus (P value = 0.001).

Conclusions:

NB-UVB has the potential to halt disease progression in some patients with progressive vitiligo; but is associated with more total NB-UVB fluence and time taken for fixing it. Progressive vitiligo patients have more pruritus as compared to patients with non-progressive vitiligo.

Evaluation of the Prevalence, Regional Phenotypic Variation, Comorbidities, Risk Factors, and Variations in Response to Different Therapeutic Modalities Among Indian Women: Proposal for the Indian Council of Medical Research-Polycystic Ovary Syndrome (ICMR-PCOS) Study

BACKGROUND

There is scanty data in India on polycystic ovary syndrome (PCOS) from several small, undersized, convenience-based studies employing differing diagnostic criteria and reporting varied regional prevalence. It is difficult to draw clear-cut conclusions from these studies; therefore, the present multicentric, well-designed, large-scale representative countrywide epidemiological study on PCOS across India was conceived with the aim to generate the actual prevalence rates of PCOS in India with a total sample size of approximately 9000 individuals.

OBJECTIVE

The primary objectives of the study are to estimate the national prevalence of PCOS in India and the burden of comorbidities and to compare the variation in efficacy of standard therapeutic modalities for metabolic dysfunction in women with PCOS.

METHODS

This multicentric umbrella study consists of three different substudies. Substudy 1 will involve recruitment of women aged 18-40 years using a multistage sampling technique from randomly selected polling booths across urban and rural areas to estimate national prevalence, phenotypic variation, and risk factors among regions. Substudy 2 involves recruitment of subjects from the community pool of substudy 1 and the institutional pool for quantitation of comorbidities among women with PCOS. Substudy 3, an interventional part of the study, aims for comparison of variation in efficacies of common treatment modalities and will be conducted only at 2 centers. The eligible consenting women will be randomized in a 1:1 ratio into 2 arms through a blinding procedure. All these women will undergo clinical, biochemical, and hormonal assessment at baseline and at 3 and 6 months. The data generated will be analyzed using the reliable statistical software SPSS (version 26).

RESULTS

The study is ongoing and is likely to be completed by April 2022. The data will be compiled and analyzed, and the results of the study will be disseminated through publications.

CONCLUSIONS

The Indian Council of Medical Research-PCOS study is the first of its kind attempting to provide accurate and comprehensive data on prevalence of PCOS in India.

Family vitiligo impact scale: A scale to measure the quality-of-life of family members of patients with vitiligo

BACKGROUND

Vitiligo places a significant psycho-social burden on caregivers and family members.

AIMS

The aim of the study was to develop and preliminarily validate a scale to measure the psychosocial impact of vitiligo on adult family members.

METHODS

Themes that emerged from qualitative interviews and a focus group discussion with family members were used to generate items for a preliminary scale, followed by pre-testing and scale development. The new scale was then tested with two comparator scales and a global question.

RESULTS

A preliminary scale with 32 items was pilot tested on 30 participants. Following this, the scale was condensed to 16 items in 12 domains that were administered to 159 participants. Scale scores ranged from 0 to 48 with a mean of 19.75 ± 12.41. The scale had excellent internal consistency with Cronbach's alpha coefficient of 0.92 (0.70-0.95) and also showed good test-retest reliability at two weeks (r = 0.946). The scale showed criterion, convergent and known group validity.

LIMITATIONS

It was conducted in a large teaching hospital which may have resulted in selection of patients with persistent or progressive disease and more worried family members. Vitiligo is highly stigmatized in our country and the performance of the scale may need to be evaluated in other communities and cultures as well where stigma is less oppressive.

CONCLUSION

Family Vitiligo Impact Scale appears to be an easy-to-complete, reliable and valid instrument to measure the psychosocial impact of vitiligo in family members of patients. It may be useful as an outcome measure in both clinical and research settings.

Modified ultrafiltration and postoperative course in patients undergoing repair of tetralogy of fallot

BACKGROUND

Expected benefits of modified ultrafiltration (MUF) include increased hematocrit, reduction of total body water and inflammatory mediators, improved left ventricular systolic function, and improved systolic blood pressure and cardiac index (CI) following cardiopulmonary bypass (CPB). This prospective randomized trial tested this hypothesis.

METHODS

Seventy-nine patients undergoing intracardiac repair of tetralogy of fallot were randomized to conventional ultrafiltration (CUF) + MUF (n = 39) or only CUF group (n = 40). The primary outcome was a change in hematocrit. Secondary outcomes were changes in peak airway pressures, ventilatory support, blood transfusions, time to peripheral rewarming, mean arterial pressure, central venous pressure, inotrope score (IS), and CI. Serum inflammatory markers were measured.

RESULTS

Baseline hematocrit was 50.6 ± 10.02 in the only CUF group whereas it was 43.9 ± 5.55 in the CUF + MUF group (p = .36). Following MUF, the CUF + MUF group had higher hematocrit (44.7 ± 0.50 g/dl) compared to the only CUF group (37.2 ± 0.49 g/dl), p ≤ .001 after adjusting for baseline hematocrit. Central venous pressure (mmHg) immediately following sternal closure was 9.27 ± 3.12 mmHg in the CUF + MUF group and 10.52 ± 2.2 mmHg in the only CUF group (p = .04). In the intensive care unit (ICU), they were 11.52 ± 2.20 mmHg in the only CUF group and 10.84 ± 2.78 mmHg in the CUF + MUF group (p = .02). Time to peripheral rewarming was 6.30 ± 3.91 h in the CUF + MUF group and 13.67 ± 3.91 h in the only CUF group (p = .06). Peak airway pressures in ICU were 17 ± 2 mmHg versus 20.55 ± 2.97 mmHg in CUF + MUF group & only CUF group, respectively, p < .001). Duration of mechanical ventilation was 6.3 ± 2.7 h in CUF + MUF group compared to 14.7 ± 3.5 h in the only CUF group (p = .002). IS was 11.52 ± 2.20 in the only CUF group compared to 10.84 ± 2.78 in CUF + MUFs group. Eight of 39 (20.5%) patients in the CUF + MUF group had IS > 10 compared to 22 of 40 (55%) patients in the only CUF group (p = .02). Serum Troponin-T and interleukin-6 levels were lower in the CUF + MUF group; TNF-α and CPK-MB were similar. ICU and hospital stay were similar.

CONCLUSION

Patients undergoing a combination of CUF and MUF had higher postoperative hematocrit, decreased duration of mechanical ventilation, lower need for inotropes and lower interleukin-6 and Troponin-T levels. This group had better postoperative outcomes. This study was registered with the Clinical trials registry of India (CTRI/2017/11/010512) before commencement.

A split-tattoo randomized Q-switched neodymium-doped yttrium-aluminium-garnet laser trial comparing the efficacy of a novel three-pass, one-session method with a conventional method in the treatment of blue/black tattoos in darker skin types

Tattoos with blue/black ink show good lightening of pigment after treatment with 1064 nm Q-switched (QS) neodymium-doped yttrium-aluminium-garnet (Nd:YAG) laser. In this randomized trial, we compared the efficacy of a novel three pass, one session procedure (R15 method) with a conventional method for treating blue/black tattoos in darker skin types. Tattoos were treated with 1064 nm QS Nd:YAG Laser with a spot size of 4 mm, fluence of 5 J/cm² and frequency of 5 Hz. The tattoo pigment lightening was comparable with both methods. Thread-like tattoos had significantly better pigment lightening with fewer side effects than the broad band-like tattoos. We would like to recommend the R15 method of the QS Nd:YAG laser for thread-like tattoos, which can save patients' time, cut short the frequency of their hospital visits and, more importantly, decrease the cost involved in it.

Alfacalcidol vs Calcitriol in the Management of Patient With Hypoparathyroidism: A Randomized Controlled Trial

CONTEXT

Alfacalcidol and calcitriol are commonly used for managing hypoparathyroidism. Their relative merits have not been systematically assessed.

OBJECTIVE

We compared the effect of alfacalcidol and calcitriol on phosphatemic control, hypercalciuria, and associated factors in idiopathic-hypoparathyroidism (IH).

DESIGN AND SETTING

Open-label randomized controlled trial, tertiary care center.

SUBJECTS AND METHODS

IH patients with optimal calcemic control on alfacalcidol were continued on the same (n = 20) or switched to calcitriol (n = 25) at half of the ongoing alfacalcidol dose. The dose was adjusted during follow-up to maintain serum total calcium between 8.0 and 9.5 mg/dL. Serum calcium, phosphorus, 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, 24-h urine calcium-to-creatinine ratio, and fractional excretion of phosphorus (FEPh) were measured at baseline and 6 months. Plasma intact-FGF23 was measured at final follow-up.

RESULT

Patients receiving alfacalcidol and calcitriol had comparable serum calcium at 6 months (8.7 ± 0.4 vs 8.9 ± 0.4 mg/dL, P = 0.13). Their median [interquartile range (IQR)] dose at 6 months was 2.0 (1.0-2.5) and 0.75 (0.5-1.0) µg/d, respectively. Serum 1,25(OH)2D levels were physiological in both (35.3 ± 11.6 and 32.3 ± 16.9 pg/mL). Serum phosphate and calcium excretion were comparable in 2 arms. A majority had hyperphosphatemia (75% vs 76%), hypercalciuria (75% vs 72%), and elevated FGF23 (116 ± 68 and 113 ± 57 pg/mL). Age showed significant independent association with plasma FGF23 (β = 1.9, P = 0.001). Average FEPh was low despite high FGF23.

CONCLUSION

At optimal calcium control, both alfacalcidol and calcitriol lead to comparable but high serum phosphate levels, hypercalciuria, physiological circulating 1,25(OH)2D, and elevated FGF23. Further studies are required to systematically investigate other treatment options.

Role of neoadjuvant chemotherapy in breast cancer patients: Systematic review and meta-analysis

Background: The present systematic review and meta-analysis critically assessed the impact of neoadjuvant chemotherapy (nACT) in comparison to ACT in breast cancer patients in terms of oncological and functional outcomes. Methods: Randomized controlled trials comparing NACT with ACT in breast cancer patients were identified through Medline and Cochrane Register of Controlled Trials on January 21, 2016. Cochrane risk of bias assessment tool was used to assess the risk of bias. Meta-analysis was performed using fixed-effects or random-effects method depending on heterogeneity (I 2). Grading of the evidences was also done. Subgroup meta-analysis on the basis of total preoperative chemotherapy or sandwich chemotherapy was also performed. Results: The present meta-analysis shows increased breast-conserving surgery (BCS) rate (n = 9, risk ratio [95% confidence interval (CI)] = 1.19 [1.03–1.37]) with NACT. Further, NACT was found equally effective regarding overall survival (n = 15, hazard ratio [HR] [95% CI] = 0.98 [0.89–1.08]), disease-free survival (DFS) (n = 14, HR [95% CI] = 1.01 [0.86–1.18]), and distant metastasis (n = 13, HR [95% CI] = 0.97 [0.82–1.16]). Although locoregional recurrence (LRR) rate was noted to be significantly higher in NACT group (n = 15, HR [95% CI] = 1.23 [1.06–1.43]), its significance disappeared (n = 13, HR [95% CI] = 1.17 [0.98–1.40]) by excluding the trials where surgery was not provided for patients with complete tumor response. After excluding such trials, preoperative NACT was associated with increased BCS with similar LRR in ACT group. Discussion: NACT has no major impact on breast cancer survival. However, it is associated with increased BCS rates. NACT downgrades tumor size facilitating more BCSs without increasing LRR. The evidences were graded for all outcomes as high except DFS and BCS as moderate.

Pazopanib based oral metronomic therapy for platinum resistant/refractory epithelial ovarian cancer: A phase II, open label, randomized, controlled trial

BACKGROUND

Treatment of patients with platinum resistant/refractory epithelial ovarian cancer (EOC) is an unmet need. We evaluated the role of oral metronomic therapy in this setting.

PATIENTS AND METHODS

Between October 2017 and September 2019 seventy five patients with platinum resistant/refractory EOC were enrolled. Patients received oral etoposide (50 mg, day 1 to 14, cyclophosphamide 50 mg, day 1 to 28, every 4 weeks (Arm A, n = 38). Patients in Arm- B (n = 37) received Pazopanib (400 mg once daily) in addition to etoposide and cyclophosphamide. Quality of life (QoL) was evaluated using the EORTC questionnaire. Serum VEGF and PDGF were estimated at baseline, after 3rd and 6th cycle. The primary endpoint was progression free survival (PFS). Secondary endpoints were overall survival (OS), toxicity and QoL.

RESULTS

Patients characteristics were well matched. Median PFS was higher in arm B, 5.1 months (95% CI 3.13 to10.33) compared to 3.4 months (95% CI 3.0 to 6.53) in arm A, p = 0.045. Median OS has 'not reached' in Arm B compared to 11.2 months (95% CI, 5.66 - not reached) in arm A, p = 0.032. Therapy was tolerated well; oral mucositis (p = 0.36) and fatigue (p = 0.08) being more in arm B. QoL assessment revealed modest improvement in 'symptom scales' in Arm B. Serum VEGF and PDGF levels decreased with therapy in both arms (Arm A-p < 0.0001, Arm B-p < 0.016).

CONCLUSION

Addition of pazopanib to etoposide and cyclophosphamide could be a novel oral combination for metronomic therapy for platinum resistant/refractory EOC.

Molecular characterization of decreased susceptibility to ceftriaxone and genotyping of Neisseria gonorrheae isolates in New Delhi, India

Data on genetic characteristics of Neisseria gonorrhoeae isolates exhibiting decreased susceptibility to extended-spectrum cephalosporins in India is deficient. In this study, we have sequenced penA, porB, mtrR and ponA and bla_TEM genes in 70 clinical isolates of NG with varying ceftriaxone MICs. Amongst these, 22 (31.4%) were PPNG. Additionally, N. gonorrheae Multiantigen Sequence Typing was performed. Fisher exact and χ² were used to evaluate significance of mutations with MICs. A total of six non-mosaic penA (Penicillin binding protein 2 [PBP2]) amino acid patterns were seen (II, IV, IX, XII, XIX, XXII) of which, pattern IX was significantly associated with decreased susceptibility to ceftriaxone. Other significant associations were noted in porB & mtrR genes. There were no mutations in bla_TEM gene. ST6069 was significantly associated with decreased susceptibility to ceftriaxone. To conclude, development of decreased susceptibility to ceftriaxone in gonococci involves cumulation of different mutations in the four chromosomal genes investigated.

Response to single oral dose vitamin D in obese vs non-obese vitamin D-deficient children

Obese individuals are prone to vitamin D deficiency because of sequestration of vitamin D in their body fat. We planned to evaluate the rise in serum 25(OH)D levels in vitamin D-deficient obese vs normal body mass index(BMI) children, after administration of identical single dose of vitamin D. Twenty-two obese and 22 normal BMI children with serum 25 (OH)D < 20 ng/mL were given single oral dose 150,000 IU vitamin D, and 25 (OH)D levels were measured at 1 week and 1 month post-intervention. Results show that rise in 25(OH)D level from baseline was about 2.2 times lesser in obese compared with children with normal BMI, both at 1 week and at 1 month. The rise in 25(OH)D from baseline to 1 month was inversely correlated to BMI (r = - 0.56, p = < 0.001), waist circumference (r = - 0.48, p = 0.001), total fat mass (r = - 0.58, p < 0.001), and fat mass index (r = - 0.59, p < 0.001).Conclusion: The obese children have a 2.2 times lower rise in serum vitamin D levels as compared with the normal BMI children for the same dose of vitamin D supplementation. What is Known: • The obese individuals are prone to vitamin D deficiency and may be given higher doses of vitamin D supplementation. What is New: • Our study demonstrates that obese children have 2.2 times lesser rise in serum 25(OH)D concentrations as compared with normal BMI children when administered similar oral dose vitamin D.

Liver involvement in patients with coeliac disease: proof of causality using IgA/anti-TG2 colocalisation techniques

AIMS

Despite clinical evidence of liver involvement in patients with coeliac disease (CeD), there is a lack of a method to prove this association.

METHODS

Of 146 treatment-naive patients with CeD, 26 had liver dysfunction. Liver biopsies and corresponding small intestinal biopsies were obtained from these 26 patients. Multicolour immunohistochemical and immunofluorescence confocal microscopic studies were performed on paraffin-embedded tissue to detect the IgA/anti-TG2 deposits. Follow-up liver biopsies were taken after a gluten-free diet.

RESULTS

Twenty-six out of the 146 patients (17.8%) with suspected coeliac-associated liver disease on histological examination revealed irregular sinusoidal dilatation in 15 (57.6%), steatohepatitis in 4 (15.3%), non-specific chronic hepatitis in 3 (11.5%), autoimmune hepatitis in 2 (7.6%) biopsies, including cirrhosis in one of them, irregular perisinusoidal fibrosis and changes of non-cirrhotic portal fibrosis in one biopsy each (3.8%). IgA/anti-tTG deposits were observed in 22 (84.6%) liver biopsies by dual immunohistochemistry technique, and in 24 (92.3%) by confocal immunofluorescence technique and in all corresponding duodenal biopsies (100%). Overall, IgA/anti-tTG deposits showed 100% sensitivity, 77% specificity and 85% positive predictive value for establishing an association of extraintestinal pathology and CeD using archived tissues. Follow-up liver biopsies could be obtained in five patients; four of them showed not only resolution of the histological lesions but disappearance of IgA/anti-tTG co-localisation.

CONCLUSIONS

Data of the present study adds to the body of evidence that liver lesions in patients with CeD are disease related and may have been caused by a similar pathogenic mechanism that causes intestinal changes.

Changes in extracellular cytokines in predicting disease severity and final clinical outcome of patients with blunt chest trauma

BACKGROUND

Chest trauma causes substantial morbidity and mortality and its severity is assessed using clinical diagnosis or scoring systems like Injury severity score (ISS) and thoracic trauma severity score (TTSS). Association of inflammatory cytokines with severity of disease and final clinical outcome is not clearly defined in patients with chest trauma. In this study, we thought to evaluate the inflammatory response in serum and bronchoalveolar lavage fluid (BALF) in chest trauma patients and correlate the level of extracellular cytokines with diseases severity and final outcome.

METHODS

A total of 65 patients with blunt chest trauma and 30 healthy controls were enrolled in this prospective observational study. Assessment of inflammatory cytokines such as Interleukin (s) - IL-5, IL-13, IL-2, IL-6, IL-9, IL-1β, IFN-γ, TNF-α, IL-17A, IL-17F,IL-4, IL-21 and IL-22 was performed in both serum and bronchoalveolar lavage fluid using 13-plex multiplex kit using fluorescence-encoded bead based immunoassays.

RESULTS

A significantly higher level of IL-13, IL-2, IL-6, IL-9, IL-1β, IFN-γ, TNF-α, IL-17A, IL-17F, IL-21 and IL-22 cytokines were observed in patients with blunt chest trauma compared to healthy controls. Level of IL-2, IL-6, IL-1β and IL-17A was significantly raised in the patients with blunt chest trauma who had a fatal outcome during the hospital stay. An elevated cytokine response of IL-13, IL-4, and IL-21 was noted in the group of patients with high (>5) thoracic trauma severity score.

CONCLUSION

Routine monitoring of the inflammatory cytokine level in patients with chest trauma may be used routinely. Longer prospective studies should be encouraged to determine the role of cytokines in patients with chest trauma in predicting the patient final clinical outcome.

Impact of a Psychodermatological Education Package on the Subjective Distress, Family Burden, and Quality of Life among the Primary Caregivers of Children Affected with Epidermolysis Bullosa

Background

Epidermolysis bullosa (EB) has profound effect on the subjective distress, family burden, and quality of life (QOL) of the primary caregivers (PCG). Knowledgeable PCG can efficiently manage children with these skin diseases and also improve their QOL.

Objectives

To assess the subjective distress, family burden, and QOL, to develop and assess the short-term effectiveness of a psycho-dermatological education package (PDEP) for the PCG of children with EB.

Methods

In this interventional study, 30 PCG of EB were assessed for subjective distress, family burden, and QOL. PDEP, a structured educational tool explaining the disease and its care and stress management, was developed by the authors for the PCG and administered to them after one month of enrolment. They were reassessed after three months and compared with the baseline assessment scores. For comparison, 37 PCG of CI were also studied.

Results

The mean age (years) of the subjects was 28.7 ± 6.7 for EB and 30.5 ± 4.6 for CI. The mean or median (range) baseline scores for subjective distress, family burden and QOL of PCG (n = 20) of EB were 8.4 ± 7.9, 6.5 (0-30); 28.5 ± 17.5, 24 (7-77) and 12.6 ± 6.7, 11.5 (4-28) and for PCG (n = 14) of CI were 12 ± 4.3, 38.9 ± 16.2 and 17.7 ± 3.6 respectively. The PDEP improved the QOL (p = 0.01), knowledge (p < 0.01) and practices (p < 0.001) for PCG of EB and it improved subjective distress (p < 0.001), QOL (p < 0.01) and knowledge (p < 0.01) for PCG of CI.

Conclusions

PDEP is an effective educational tool in improving the QOL and knowledge of PCG, which in turn provides efficient management and psychological support to children affected with EB and CI. It should, therefore, be routinely used for educating the PCG of children with EB and CI.

Efficacy of Low-Frequency Repetitive Transcranial Magnetic Stimulation in Ischemic Stroke: A Double-Blind Randomized Controlled Trial

Objective

To investigate the role of low-frequency repetitive transcranial magnetic stimulation (rTMS) along with conventional physiotherapy in the functional recovery of patients with subacute ischemic stroke.

Design

Double-blind, parallel group, randomized controlled trial.

Setting

The outpatient department of a tertiary hospital participants: first ever ischemic stroke patients (N=96) in the previous 15 days were recruited and were randomized after a run-in period of 75±7 days into real rTMS (n=47) and sham rTMS (n=49) groups.

Intervention

Conventional physical therapy was given to both the groups for 90±7 days postrecruitment. Total 10 sessions of low-frequency rTMS on contralesional premotor cortex was administered to real rTMS group (n=47) over a period of 2 weeks followed by physiotherapy regime for 45-50 minutes.

Main Outcome Measures

The primary efficacy outcomes were change in modified Barthel Index (mBI) score (pre- to postscore) and proportion of participants with mBI score more than 90, measured at 90±7 days postrecruitment. The secondary outcomes were change in Fugl-Meyer Assessment–upper extremity, Fugl-Meyer Assessment–lower extremity, Hamilton Depression Scale, modified Rankin Scale, and National Institute of Health and Stroke Scale (pre- to post-rTMS) scores at 90±7 days post recruitment.

Results

Modified intention to treat analysis showed a significant increase in the mBI score from pre- to post-rTMS in real rTMS group (4.96±4.06) versus sham rTMS group (2.65±3.25). There was no significant difference in proportion of patients with mBI>90 (55% vs 59%; P=.86) at 3 months between the groups.

Conclusion

In patients with subacute ischemic stroke, 1-Hz low-frequency rTMS on contralesional premotor cortex along with conventional physical therapy resulted in significant change in mBI score.

Prognostic and Therapeutic Potentials of OncomiRs Modulating mTOR Pathways in Virus-Associated Hepatocellular Carcinoma

Background

Dysregulated oncomiRs are attributed to hepatocellular carcinoma (HCC) through targeting mTOR signaling pathway responsible for cell growth and proliferation. The potential of these oncomiRs as biomarker for tumor response or as target for therapy needs to be evaluated.

AIM

Tumor response assessment by OncomiR changes following locoregional therapy (LRT) and targeting of these oncomiRs modulating pathway

Methods

All consecutive viral-HCC patients of BCLC stage-A/B undergoing LRT were included. OncomiRs (miR-21, -221, and -16) change in circulation and AFP-ratio at 1-month post-LRT to baseline was estimated to differentiate various categories of response as per mRECIST criteria. OncomiR modulating mTOR pathway was studied by generating miR-21 and miR-221 overexpressing Huh7 stable cell lines.

Results

Post-LRT tumor response was assessed in 90 viral-HCC patients (CR, 40%; PR, 31%, and PD, 29%). Significant increase of miRNA-21 and -221 expression was observed in PD (p = 0.040, 0.047) and PR patients (miR-21, p = 0.045). Fold changes of miR-21 can differentiate response in group (CR from PR+PD) at AUROC 0.718 (95% CI, 0.572–0.799) and CR from PD at AUROC 0.734 (95% CI, 0.595–0.873). Overexpression of miR-21 in hepatoma cell line had shown increased phosphorylation p70S6K, the downstream regulator of cell proliferation in mTOR pathway. Upregulation of AKT, mTOR, and RPS6KB1 genes were found significant (P < 0.005) and anti-miR-21 specifically reduced mTOR gene (P = 0.02) expression.

Conclusions

The miR-21 fold change correlates well with imaging in predicting tumor response. Overexpression of miR-21 has a role in HCC through mTOR pathway activation and can be targeted.

Quality of life in paediatric solid tumours: a randomised study of metronomic chemotherapy versus placebo

OBJECTIVE

Health-related quality of life (HRQoL) is an important outcome for paediatric cancer studies. We compared the HRQoL between patients of progressive paediatric solid tumours randomised to metronomic chemotherapy versus placebo.

METHODS

In this double-blinded, placebo-controlled randomised study of 108 children with progressive malignancies, HRQoL was evaluated using the PedsQOL Cancer module V.3 at baseline (A1), A2 (9 weeks or earlier if progressed) or A3 (18 weeks or earlier if progressed).

RESULTS

There was no statistically significant difference in the change in quality of life produced by each arm from A1 to A2 in either mean total scores or individual domain scores, reported by children or their parents. On analysing the response according to the minimal clinically important difference, defined as an improvement by 4.5 points, we found no significant differences, be it among bone-sarcomas, other tumours, responders (those who received ≥9 weeks of treatment) or non-responders.

CONCLUSIONS

The present study concludes that there was no significant difference in HRQoL, between the patients in the two arms at second and later assessments. This is consistent with the other survival endpoints in the study.

Prevalence, pattern & correlates of hypertension among tribal population of Kashmir, India: A cross-sectional study

Background & objectives:

The prevalence of hypertension is increasing among all ethnic groups across the globe with only a handful of studies from India addressing the prevalence of hypertension among tribal population. In view of paucity of data, this study was aimed at estimating the prevalence of hypertension and associated risk factors among tribal population of Kashmir, India.

Methods:

This cross-sectional survey included 6808 tribals aged >20 yr (5695 Gujjars and 1113 Bakarwals) from five randomly selected districts of Kashmir. Modified WHO-STEPS surveillance questionnaire was used to collect relevant data. Hypertension was defined by Joint National Committee on Prevention, Detection, Evaluation and Treatment of Hypertension (JNC 8) criteria.

Results:

The mean age of our study participants was 43.12 ± 15.69 years. Overall prevalence of hypertension [95% confidence interval (CI)] was 41.4% (39.9-42.9%) [men=46.7% (44.1-49.1%); women=37.9% (35.9-39.9%)]. The prevalence of prehypertension (95% CI) in our study was 35 per cent (33.7-36.6%). Higher age [adjusted odds ratio (OR) (95% CI): >70 yr-2.2 (1.9-2.4)], passive smoking [OR-1.3 (1.1-1.5)], family history of hypertension [OR-1.6 (1.4-1.7)] and obesity [OR-1.3 (1.1-1.6)] were significantly associated with hypertension. A weak positive correlation was observed between BP (systolic/diastolic) with haemoglobin, red blood cell count and haematocrit (P<0.05).

Interpretation & conclusions:

Gujjar and Bakarwal tribes of Jammu and Kashmir showed high prevalence of hypertension. Hence, urgent policies and reforms are needed to tackle this silent epidemic and further studies focusing on community-based interventions are required.

Histological analyses of trucut liver biopsies from patients with noncirrhotic portal fibrosis and extra-hepatic portal vein obstruction

Background

Both noncirrhotic portal fibrosis (NCPF) and extrahepatic portal venous obstruction (EHPVO) are important causes of noncirrhotic portal hypertension (PH) in the Asian region. In this study, we analyzed the histopathological changes of liver needle-core biopsies from patients with NCPF and EHPVO.

Patients and Methods

The patients were diagnosed as per the Asia Pacific Association for the Study of Liver (APASL) criteria. Minimum adequacy criteria for liver core biopsies were defined, and finally, 69 liver biopsies from patients with NCPF and 100 liver biopsies from patients with EHPVO were analyzed. All histological parameters were predefined, and three experienced pathologists analyzed the biopsies after reaching consensus. Institute ethics committee clearance was taken.

Results

Although some histological features were overlapping, phlebosclerosis of intra-hepatic branches of the portal vein (PV), periportal aberrant vascular channels, remnant portal tracts, and hepatic fibrosis beyond the portal tracts without the formation of complete hepatic nodules (P < 0.001 for all) were common histological characteristics of NCPF on core-needle liver biopsies; while maintained lobular architecture, nonspecific dilatation of PV branches, absence of intra-hepatic PV phlebosclerosis, aberrant vascular channels, and significant fibrosis were characteristics of EHPVO.

Conclusions

Despite the considerable histological overlap between NCPF and EHPVO, careful histological evaluation, supplemented by clinical features, radiological and biochemical findings can help in making a conclusive diagnosis. Patients with NCPF and EHPVO with clinical jaundice show transaminitis, high serum alkaline phosphatase level, more variceal bleed, and histological evidences of nodular regenerative hyperplasia.

Burden of influenza-associated respiratory and circulatory mortality in India, 2010-2013

Background

Influenza causes substantial morbidity and mortality worldwide, however, reliable burden estimates from developing countries are limited, including India. We aimed to quantify influenza-associated mortality for India utilizing 2010-2013 nationally representative data sources for influenza virus circulation and deaths.

Methods

Virological data were obtained from the influenza surveillance network of 10 laboratories led by National Institute of Virology, Pune covering eight states from 2010-2013. Death data were obtained from the nationally representative Sample Registration System for the same time period. Generalized linear regression with negative binomial distribution was used to model weekly respiratory and circulatory deaths by age group and proportion of specimens positive for influenza by subtype; excess deaths above the seasonal baseline were taken as an estimate of influenza-associated mortality counts and rates. Annual excess death rates and the 2011 India Census data were used to estimate national influenza-associated deaths.

Results

Estimated annual influenza-associated respiratory mortality rates were highest for those ≥65 years (51.1, 95% confidence interval (CI) = 9.2-93.0 deaths/100 000 population) followed by those <5 years (9.8, 95% CI = 0-21.8/100 000). Influenza-associated circulatory death rates were also higher among those ≥65 years (71.8, 95% CI = 7.9-135.8/100 000) as compared to those aged <65 years (1.9, 95% CI = 0-4.6/100 000). Across all age groups, a mean of 127 092 (95% CI = 64 046-190,139) annual influenza-associated respiratory and circulatory deaths may occur in India.

Conclusions

Estimated influenza-associated mortality in India was high among children <5 years and adults ≥65 years. These estimates may inform strategies for influenza prevention and control in India, such as possible vaccine introduction.

IMPACT OF MOLECULAR METHOD FOR THE DIAGNOSIS OF ACUTE BACTERIAL MENINGITIS IN A TERTIARY HEALTH CARE CENTRE IN NORTH INDIA

Background. Acute bacterial meningitis is one of the significant infectious diseases that add an immense burden to the health system. Proper management of meningitis is an invincible need to overcome the severe consequences. Objectives. The aim of the study is detection of the etiological agents of acute bacterial meningitis by PCR. Methods. Total 267 CSF samples collected from suspected bacterial meningitis cases were processed for the detection of S. pneumoniae, H. influenzae, N. meningitidis, E. coli and Group B streptococci by conventional and molecular diagnosis method. CSF was inoculated on Blood, chocolate and MacConkey agar plates and incubated at 37 °C for 24-48 hrs. Bacteria grown were identified by Matrix assisted laser desorption/ionization time of flight (MALDI-TOF). Multiplex PCR of the enlisted bacteria was performed using DNA extracted from CSF by DNA extraction kit (Qiagen, USA). Results. 5 (1.87%) out of the total 267 CSF samples were culture positive (3 S. pneumoniae and 2 E. coli) and 28 (10.49%) had detectable DNA by conventional PCR. Out of these 28 samples, 20 (71.43%) were S. pneumoniae and 8 (28.57%) were E. coli. 15 (53.57%) out of total S. pneumoniae were present in children below 5 years of age. Similarly, E. coli was predominant in neonates. Sensitivity and specificity of the PCR was 100% and 95-98% respectively. Conclusions. Streptococcus pneumoniae is the commonest cause of community acquired bacterial meningitis in children below five years of age. Hence, for the promising outcome, PCR should be implemented for the diagnosis of acute bacterial meningitis.

Circulating miR-133b and miR-21: potential non-invasive diagnostic biomarkers of coronary artery disease

Background

While coronary artery disease (CAD) has become a major threat worldwide, the timely biomarker-based early diagnosis of CAD remains a major unmet clinical challenge.

Purpose

We aimed towards assessing the level of circulatory microRNAs as candidates of novel biomarkers in early diagnosis of CAD.

Methods

A total of 147 subjects were recruited from Delhi and surrounding regions which includes 78 subjects with angiographically proven CAD, 15 pre-atherosclerotic normal coronary artery (NCA) subjects and 54 healthy individuals. Quantitative real-time PCR assays were performed using total RNA isolated from plasma of CAD patients and healthy individuals in order to measure the relative expression profiles of circulating miR-133b and miR-21. The severity level of the disease in each individual was assessed on the basis of number of diseased vessels involved and extent of stenosis.

Results

MiR-133b was found to be significantly downregulated (p&lt;0.05) by 4.6 fold whereas miR-21 was significantly upregulated (p&lt;0.05) by ∼2 fold in plasma samples of CAD patients as compared to healthy individuals. Importantly, both the miRNAs showed an association with disease severity as miR-133b was downregulated by 8.45 fold in acute coronary syndrome (ACS), 3.38 fold in Stable angina (SA) and 2.08 fold in NCA. MiR-21 was upregulated by 2.46 fold in ACS, 1.90 fold in SA and 1.12 fold in NCA. Moreover, miR-133b could significantly differentiate subjects with ST-elevation myocardial infarction (STEMI) from Non-STEMI. Both the miRNAs exhibited a noteworthy diagnostic potential as translated through an upstanding sensitivity and specificity. MiR-133b showed an area under the curve (AUC): 0.80 with 75.6% sensitivity and 76% specificity at recommended optimal cut-off point of 14.0 whereas, miR-21 showed and AUC value of 0.79 with 72.2% sensitivity and 69.4% specificity at optimal cut-off point of 5.59 as assessed by receiver operating characteristics (ROC) curve analysis.

Conclusions

The reduced expression of miR-133b and elevated expression level of miR-21 in plasma suggest their significant role in the pathophysiology as well as their implication towards the individual's susceptibility in developing CAD. Thus, we conclude that these two circulating miRNAs could be possible candidates of non-invasive biomarkers in the early prediction and diagnosis of CAD.

Is Endoscopic Third Ventriculostomy a Feasible Option or Ventriculoperitoneal Shunt a Safer Bet for the Treatment of Posttraumatic Hydrocephalus? A Gap Time Model-based Algorithm

Background

Posttraumatic hydrocephalus (PTH) adds to the morbidity and mortality of traumatic brain injury (TBI) and there are insufficient clinical data to suggest usefulness of ventriculoperitoneal shunt (VPS) over endoscopic third ventriculostomy (ETV) in PTH or vice versa.

Objective

To evaluate the usefulness of VPS and ETV in the treatment of PTH and to establish the indications for their usage.

Materials and Methods

This was an ambispective study of 141 patients who developed PTH out of 2500 cases of TBI treated during the study duration (2012-2016). These patients were segregated into two groups depending on the primary procedure for PTH-ETV group and VPS group. The two groups were compared to analyze the differences in radiological and clinical outcome.

Results

141 patients were included in the study and 175 procedures were performed in these patients. ETV group had 30 procedures and VPS had 145 procedures. In the ETV group, 37% of cases showed improvement v/s 73% cases in the VPS group. A statistically significant number of patients had improvement in presenting symptoms in the VPS group, as compared with the ETV group (P = 0.001). There was no significant difference in Glasgow coma scale (GCS) at discharge (P = 0.15) and Glasgow outcome score at 6 months of follow-up (P = 0.22) between the two groups. Poor GCS, previous cerebrospinal fluid infection, and postoperative meningitis were found to have significant effect on the failure-free period of the procedure. On comparing the probabilities of failure-free period of ETV v/s VPS, the chances of VPS failure are 61% lesser than ETV.

Conclusions

VPS is an effective modality for the management of PTH and has a much lower failure rate as compared to ETV. However, ETV can be considered as a salvage procedure in difficult situations of recurrent shunt malfunction or infection.

A split face randomized controlled trial comparing 1,064 nm Q-switched Nd-YAG laser and modified Kligman's formulation in patients with melasma in darker skin

BACKGROUND

No randomized studies compared the efficacy and safety of modified Kligman's triple combination (TC) with 1,064 nm Q-switched Nd-YAG laser (QSNYL) in melasma in darker skin.

OBJECTIVES

To compare the efficacy and safety of QSNYL and TC in the treatment of melasma in Fitzpatrick skin types IV and V.

METHODS

In this split face randomized controlled trial, participants' cheeks were randomized to receive either weekly QSNYL (group A) or daily TC (group B) for 12 weeks, followed by 12 weeks of follow-up.

RESULTS

Twenty-eight patients completed the intervention, and 21 of them completed follow-up. We found a significant but modest reduction in mean melanin index, modified Melasma Area Severity Index (MASI), and photographic and patient's assessment in both modalities (P < 0.01). No significant differences were detected between the groups. All patients had reappearance of pigmentation by the end of follow-up. Adverse reactions were significantly more in group B (P < 0.001).

LIMITATION

The desired sample size could not be achieved.

CONCLUSION AND RELEVENCE

No statistically significant differences were observed between QSNYL and TC as monotherapy in melasma. Reappearance of melasma is inevitable after stopping treatment.

Evaluation of a Chip-Based, Point-of-Care, Portable, Real-Time Micro PCR Analyzer for the Detection of High-Risk Human Papillomavirus in Uterine Cervix in India

PURPOSE

Currently available human papillomavirus (HPV) detection devices are expensive, requiring a continuous power supply, high-priced reagents, skilled laboratory personnel, and infrastructure. These make it difficult to implement primary HPV screening in high-risk (HR) populations, particularly in low-income settings such as in India. The objective of our study was to evaluate the diagnostic performance of a point-of-care, portable, battery-operated device called Truenat, which detects 4 HR HPV genotypes (16, 18, 31, and 45), as a potentially cost-effective alternative to conventional HPV diagnostic tests.

PATIENTS AND METHODS

This was a single-site, blinded, cross-sectional study that evaluated the performance of the Trunat HPV-HR using cervical samples collected from nonpregnant women > 30 years old via consecutive sampling. The comparison was conducted against the Hybrid Capture 2 (HC2) method. All the positive samples were validated by 14 Real-TM Quant Kit.

RESULTS

Of 615 cervical samples, the HR-HPV DNA test was positive in 78 women (12.7%) by HC2 and in 49 (8%) by Truenat. With the consideration of limited genotype inclusivity, the sensitivity and specificity of Truenat HPV-HR were 97.7% and 98.9%, respectively.

CONCLUSION

The performance of Truenat HPV-HR test was comparable to that of HC2 in the 4 HPV genotypes and would be appropriate to consider for use in primary HR cervical cancer screening and particularly in low-income settings.

Validation of the diagnostic criteria for segmental vitiligo

Background

Segmental vitiligo has a different clinical course and prognosis as compared to nonsegmental vitiligo, which necessitates its correct diagnosis. It may be difficult to distinguish segmental vitiligo from the limited or focal types of nonsegmental vitiligo.

Objective

To validate the previously proposed diagnostic criteria for segmental vitiligo.

Methods

This was a cross-sectional validation study involving patients with limited vitiligo. The diagnostic criteria were used to classify vitiligo lesions as segmental or nonsegmental, and was compared with the experts' diagnosis, which was considered as the "gold standard".

Results

The study included 200 patients with 225 vitiligo lesions. As per the diagnostic criteria, 146 vitiligo lesions were classified as segmental and 79 as nonsegmental. The experts classified 147 vitiligo lesions as segmental and 39 as nonsegmental, while the diagnosis either was labeled "unsure" or could not be agreed upon for 39 lesions. As compared with the experts' opinions ("for sure" cases, n = 186), the sensitivity and specificity of the diagnostic criteria was 91.8% (95% confidence interval [CI]: 86.2%-95.7%) and 100% (95% CI: 91%-100%), respectively. The positive predictive value was 100% (95% CI: 97.3-100%), while the negative predictive value was 76.5% (95% CI: 62.5%-87.2%). There was a 93.5% agreement between the clinical criteria and experts' opinions (k = 0.83, P < 0.001).

Limitation

The diagnostic criteria were compared with the experts' opinion in the absence of an established diagnostic "gold standard".

Conclusions

The proposed diagnostic criteria for segmental vitiligo performed well, and can be used in clinical practice, as well as in research settings.

Detection of mycobacterial CFP-10 (Rv3874) protein in tuberculosis patients by gold nanoparticle-based real-time immuno-PCR

Aim: Timely and reliable diagnostic test for tuberculosis (TB) is immediately required. Attempts were made to improve the technology and diagnostic potential of real-time immuno-PCR (RT-I-PCR). Methods: We designed gold nanoparticle (GNP)-based RT-I-PCR (GNP-RT-I-PCR) assay for the detection of Mycobacterium tuberculosis CFP-10 (Rv3874) protein in clinical samples of TB patients. Results: A wide quantitative detection range of CFP-10 was found to be 0.5-5 × 10⁴ pg/ml in bodily fluids of TB patients, which can evaluate the progression of disease. Moreover, sensitivities of 83.7 and 76.2% were observed in pulmonary (n = 49) and extrapulmonary TB (n = 42) patients, respectively, with specificities of 93.5-93.8% (n = 63). Conclusion: Conjugation of detection antibodies and oligonucleotides to functionalized GNPs of GNP-RT-I-PCR is relatively easier, compared with streptavidin-biotin/succinimidyl-4-(N-maleimidomethyl) cyclohexane-1-carboxylate system employed in RT-I-PCR. Our assay also showed better diagnostic performance than RT-I-PCR, which may provide a viable platform for the development of an efficient TB diagnostic test.

Comparison of statistical methods for recurrent event analysis using pediatrics asthma data

When the same type of event is experienced by a subject more than once it is called recurrent event, which possess two important characteristics, namely "within-subject correlation" and "time-varying covariate." As a result, the traditional statistical methods do not work well on recurrent event data. Over the past few decades, many alternatives methods have been proposed for the analysis of recurrent event data. In this article, the six most prominent methods for recurrent event analysis have been compared on pediatric asthma data. Three variance corrected models (viz "Anderson and Gill [AG] model," "Prentice, William, and Peterson-Counting Process [PWP-CP] model," and "Prentice, William, and Peterson-Gap Time [PWP-GT] model") and three corresponding frailty variants (AG-frailty, PWP-CP-frailty, and PWP-GT-frailty) were compared using three mathematical criterion (AIC, BIC, and log-likelihood) and one graphical criteria (Cox-Snell goodness of fit, visual test). All model comparison indices showed the PWP-GT model as the most appropriate model on asthma data over other models. By using PWP-GT model, seven predictors of asthma exacerbation (viz "abdominal pain at previous visit," "Z5 (%) at previous visit," "diagnosis of asthma at previous visit," "calendar month of exacerbation," "history of maternal asthma," "monthly per capita income," and "emotional stress") were identified. The PWP-GT model was identified as the most appropriate model over other models on pediatrics asthma data.

Subnational mapping of under-5 and neonatal mortality trends in India: the Global Burden of Disease Study 2000-17

BACKGROUND

India has made substantial progress in improving child survival over the past few decades, but a comprehensive understanding of child mortality trends at disaggregated geographical levels is not available. We present a detailed analysis of subnational trends of child mortality to inform efforts aimed at meeting the India National Health Policy (NHP) and Sustainable Development Goal (SDG) targets for child mortality.

METHODS

We assessed the under-5 mortality rate (U5MR) and neonatal mortality rate (NMR) from 2000 to 2017 in 5 × 5 km grids across India, and for the districts and states of India, using all accessible data from various sources including surveys with subnational geographical information. The 31 states and groups of union territories were categorised into three groups using their Socio-demographic Index (SDI) level, calculated as part of the Global Burden of Diseases, Injuries, and Risk Factors Study on the basis of per-capita income, mean education, and total fertility rate in women younger than 25 years. Inequality between districts within the states was assessed using the coefficient of variation. We projected U5MR and NMR for the states and districts up to 2025 and 2030 on the basis of the trends from 2000 to 2017 and compared these projections with the NHP 2025 and SDG 2030 targets for U5MR (23 deaths and 25 deaths per 1000 livebirths, respectively) and NMR (16 deaths and 12 deaths per 1000 livebirths, respectively). We assessed the causes of child death and the contribution of risk factors to child deaths at the state level.

FINDINGS

U5MR in India decreased from 83·1 (95% uncertainty interval [UI] 76·7-90·1) in 2000 to 42·4 (36·5-50·0) per 1000 livebirths in 2017, and NMR from 38·0 (34·2-41·6) to 23·5 (20·1-27·8) per 1000 livebirths. U5MR varied 5·7 times between the states of India and 10·5 times between the 723 districts of India in 2017, whereas NMR varied 4·5 times and 8·0 times, respectively. In the low SDI states, 275 (88%) districts had a U5MR of 40 or more per 1000 livebirths and 291 (93%) districts had an NMR of 20 or more per 1000 livebirths in 2017. The annual rate of change from 2010 to 2017 varied among the districts from a 9·02% (95% UI 6·30-11·63) reduction to no significant change for U5MR and from an 8·05% (95% UI 5·34-10·74) reduction to no significant change for NMR. Inequality between districts within the states increased from 2000 to 2017 in 23 of the 31 states for U5MR and in 24 states for NMR, with the largest increases in Odisha and Assam among the low SDI states. If the trends observed up to 2017 were to continue, India would meet the SDG 2030 U5MR target but not the SDG 2030 NMR target or either of the NHP 2025 targets. To reach the SDG 2030 targets individually, 246 (34%) districts for U5MR and 430 (59%) districts for NMR would need a higher rate of improvement than they had up to 2017. For all major causes of under-5 death in India, the death rate decreased between 2000 and 2017, with the highest decline for infectious diseases, intermediate decline for neonatal disorders, and the smallest decline for congenital birth defects, although the magnitude of decline varied widely between the states. Child and maternal malnutrition was the predominant risk factor, to which 68·2% (65·8-70·7) of under-5 deaths and 83·0% (80·6-85·0) of neonatal deaths in India could be attributed in 2017; 10·8% (9·1-12·4) of under-5 deaths could be attributed to unsafe water and sanitation and 8·8% (7·0-10·3) to air pollution.

INTERPRETATION

India has made gains in child survival, but there are substantial variations between the states in the magnitude and rate of decline in mortality, and even higher variations between the districts of India. Inequality between districts within states has increased for the majority of the states. The district-level trends presented here can provide crucial guidance for targeted efforts needed in India to reduce child mortality to meet the Indian and global child survival targets. District-level mortality trends along with state-level trends in causes of under-5 and neonatal death and the risk factors in this Article provide a comprehensive reference for further planning of child mortality reduction in India.

Mapping of variations in child stunting, wasting and underweight within the states of India: the Global Burden of Disease Study 2000-2017

BACKGROUND

To inform actions at the district level under the National Nutrition Mission (NNM), we assessed the prevalence trends of child growth failure (CGF) indicators for all districts in India and inequality between districts within the states.

METHODS

We assessed the trends of CGF indicators (stunting, wasting and underweight) from 2000 to 2017 across the districts of India, aggregated from 5 × 5 km grid estimates, using all accessible data from various surveys with subnational geographical information. The states were categorised into three groups using their Socio-demographic Index (SDI) levels calculated as part of the Global Burden of Disease Study based on per capita income, mean education and fertility rate in women younger than 25 years. Inequality between districts within the states was assessed using coefficient of variation (CV). We projected the prevalence of CGF indicators for the districts up to 2030 based on the trends from 2000 to 2017 to compare with the NNM 2022 targets for stunting and underweight, and the WHO/UNICEF 2030 targets for stunting and wasting. We assessed Pearson correlation coefficient between two major national surveys for district-level estimates of CGF indicators in the states.

FINDINGS

The prevalence of stunting ranged 3.8-fold from 16.4% (95% UI 15.2-17.8) to 62.8% (95% UI 61.5-64.0) among the 723 districts of India in 2017, wasting ranged 5.4-fold from 5.5% (95% UI 5.1-6.1) to 30.0% (95% UI 28.2-31.8), and underweight ranged 4.6-fold from 11.0% (95% UI 10.5-11.9) to 51.0% (95% UI 49.9-52.1). 36.1% of the districts in India had stunting prevalence 40% or more, with 67.0% districts in the low SDI states group and only 1.1% districts in the high SDI states with this level of stunting. The prevalence of stunting declined significantly from 2010 to 2017 in 98.5% of the districts with a maximum decline of 41.2% (95% UI 40.3-42.5), wasting in 61.3% with a maximum decline of 44.0% (95% UI 42.3-46.7), and underweight in 95.0% with a maximum decline of 53.9% (95% UI 52.8-55.4). The CV varied 7.4-fold for stunting, 12.2-fold for wasting, and 8.6-fold for underweight between the states in 2017; the CV increased for stunting in 28 out of 31 states, for wasting in 16 states, and for underweight in 20 states from 2000 to 2017. In order to reach the NNM 2022 targets for stunting and underweight individually, 82.6% and 98.5% of the districts in India would need a rate of improvement higher than they had up to 2017, respectively. To achieve the WHO/UNICEF 2030 target for wasting, all districts in India would need a rate of improvement higher than they had up to 2017. The correlation between the two national surveys for district-level estimates was poor, with Pearson correlation coefficient of 0.7 only in Odisha and four small north-eastern states out of the 27 states covered by these surveys.

INTERPRETATION

CGF indicators have improved in India, but there are substantial variations between the districts in their magnitude and rate of decline, and the inequality between districts has increased in a large proportion of the states. The poor correlation between the national surveys for CGF estimates highlights the need to standardise collection of anthropometric data in India. The district-level trends in this report provide a useful reference for targeting the efforts under NNM to reduce CGF across India and meet the Indian and global targets.

Detection of Mycobacterium tuberculosis lipoarabinomannan and CFP-10 (Rv3874) from urinary extracellular vesicles of tuberculosis patients by immuno-PCR

Extracellular vesicles (EVs), the small circulating vesicles released from urine samples of tuberculosis (TB) patients, contain a pool of biomarkers. We recently detected Mycobacterium tuberculosis lipoarabinomannan (LAM) and CFP-10 (Rv3874) biomarkers from the urinary EVs of pulmonary TB (PTB) and extrapulmonary TB (EPTB) patients by immuno-polymerase chain reaction (I-PCR) assay and the results were compared with the analogous enzyme-linked immunosorbent assay (ELISA). The detection limits of both purified LAM and CFP-10 were determined to be 1 fg/mL with I-PCR, which was 106 times lower than ELISA. Detection of LAM and CFP-10 biomarkers in urinary EVs of TB patients by I-PCR showed superiority over ELISA. Notably, LAM I-PCR revealed sensitivities of 74.3 and 67.9% in PTB (n = 74) and EPTB (n = 53) patients, respectively, with specificities of 91.5-92.8% (n = 116). Moreover, the sensitivities attained with LAM I-PCR were significantly higher (P < 0.01) than with CFP-10 I-PCR. After further improving the sensitivity and specificity of the assay, our I-PCR based on LAM detection in urinary EVs may be used as an adjunct test for rapid diagnosis of TB.

Antibiotic stewardship initiative in a Medicine unit of a tertiary care teaching hospital in India: A pilot study

Background & objectives:

The models for implementation of antibiotic stewardship programme (ASP) in the acute care settings of developing countries are lacking. In most of the hospitals, patient turnover is high and a proper system for recording antibiotic-related information and tracking hospital-acquired infections is not in place. This pilot study was conducted in a tertiary care teaching hospital in north India to assess the feasibility of implementation of an ASP in a Medicine unit and to evaluate the effect of implementation as per the criteria applicable in this set up.

Methods:

A pre-post-quasi-experimental non-randomized study was conducted in two phases. In the first phase, current practices in the Medicine wards were observed. In the second phase, the ASP was implemented in a single Medicine unit, along with prospective audit and feedback, tracking of the process, as well as outcome measures. Patient risk stratification, blood culture on day one, day 3 bundle, dose optimization, de-escalation and intravenous to oral conversion of antibiotics were the key elements focused upon.

Results:

There was a significant improvement in the appropriateness of antibiotic prescription (66 vs. 86%, P<0.001) and reduction in the mean number of antibiotics used per person (4.41 vs. 3.86, P<0.05) along with decrease in the duration of hospital stay (17 vs. 14 days, P<0.05). There was a significant improvement in sending of blood cultures on day one during the stewardship phase (P<0.001).

Interpretation & conclusions:

The ASP approach used in our pilot study may be feasible and beneficial. However, it needs further confirmation in other settings and on a large scale.
