Abstract
We present novel results on the free base 5,10,15,20-meso-tetra(pyridyl)-21H,23H-porphyrin (H2TPyP). This molecule presents complex electronic and vibrational properties and despite the vast literature reporting the transitions observed in its absorption and fluorescence spectra, a more accurate interpretation has been kept elusive. In particular, we show that the molecule's Q-band develops into many electronic and vibronic transitions, whose the well-known "four orbital model" finds it difficult to reconcile. Using distinct spectroscopy techniques, we conclude that both Qx- and Qy-bands comprise, in fact, two quasi-degenerated electronic states together with their respective vibronic progressions each. The analysis of the Huang-Rhys factors and complementary time- and polarization-resolved measurements reinforce the need for the proposed Q-band multi features remodeling.

Abstract
Infections caused by non-tuberculous mycobacteria (NTM) often escape detection on traditional diagnostics. We evaluated the ability of heat shock protein 65 (hsp65) polymerase chain reaction and high-resolution melting curve (HRMC) analysis to identify and differentiate Mycobacterium tuberculosis complex (MTC) from NTM in 150 clinical mycobacterial isolates from extra-pulmonary sites. A hundred MTC and 50 NTM isolates were identified. We were able to simultaneously differentiate between seven mycobacterial species using HRMC analysis; a concordance of 100% between hsp65 HRMC analysis, polymerase chain reaction + restriction analysis and hsp65 sequencing was observed.

Abstract
The muga silkworm, Antheraea assamensis, is exclusively present in the northeastern regions of India and rearing of this silkworm is a vocation unique to this region in the world. Through culture-dependent techniques, generic identification using 16S ribosomal RNA probes, diversity analysis and qualitative screening for enzyme activities, our studies have identified a number of bacterial isolates, viz. Bacillus spp., Serratia marcescens, Stenotrophomonas maltophilia, Pseudomonas stutzeri, Acinetobacter sp. and Alcaligens sp., inhabiting the gut of the muga silkworm. Analysis of the culturable bacterial community from the gut of An. assamensis revealed that Bacillus (54%) was the predominant bacterial genus followed by Serratia (24%), Pseudomonas (10%) and Alcaligens (6%). Significant differences in the Shannon-Wiener (H') and Simpson (D) diversity indices of gut bacteria were recorded for An. assamensis collected from different regions. H' and D values were found to be highest for An. assamensis from the Titabar region (H' = 4.73 ± 0.43; D = 10.00 ± 0.11) and lowest for individuals from the Mendipathar region (H' = 2.1 ± 0.05; D = 0.04 ± 0.00) of northeastern India. Qualitative screening for enzyme activities identified about 26 gut bacterial isolates having significantly higher cellulose, amylase and lipase activities. These isolates probably contribute to the digestion and nutrition of their host insect, An. assamensis.

Abstract
BACKGROUND/INTRODUCTION Nutritional studies have indicated a critical role of dietary habits in development of cardiovascular diseases (CVD). AIM We aimed to compare the risk of coronary artery disease (CAD) in habitual 'breakfast skippers' with those of 'habitual breakfast eaters' in Western part of India. We also planned to compare the cardiometabolic profiles of both the groups. DESIGN In this prospective, case-control study of 1607 individuals; 980 were patients of CAD (cases) undergoing various cardiac interventions for revascularisation and other 627 were healthy individuals (controls) who were free from CAD. METHODS Details of demographics and classical risk factors were collected for all the participants. Subjects were categorized as 'breakfast eater' or 'breakfast skippers' according to their response to the questionnaire. Logistic regression and correlation analysis were performed to assess the independent risk of all the factors and their inter-variable association. RESULTS Significantly (P < 0.05) high prevalence of classical risk factors and breakfast skipping habit was found in cases when compared with controls. Diabetes showed the highest odds ratio (7.296; 95% confidence interval (CI) 4.825-11.030; P < 0.0001) for CAD, followed by hypertension (3.756; 95% CI 2.891-4.881; P < 0.0001) and habits of smoking/tobacco/alcohol consumption (1.914; 95% CI 1.528-2.398; P < 0.0001) and breakfast skipping 1.348 (95% CI 1.076-1.689; P < 0.0001). Breakfast skipping emerged as stronger risk factor than obesity and sedentary life style in Indians and showed close association with presence of hypertension. DISCUSSION/CONCLUSION Habitual breakfast skippers are at increased risk for development of CAD and hypertension in Western India.

Abstract
The incidence of hypocalcemia and bone mineral density (BMD) changes in end-stage renal disease (ESRD) patients on denosumab remains unclear. We performed this meta-analysis to assess the incidence of denosumab-associated hypocalcemia and effects of denosumab on BMD in ESRD patients. A literature search was conducted using MEDLINE, EMBASE, and Cochrane Database from inception through November 2017 to identify studies evaluating incidence of denosumab-associated hypocalcemia and changes in serum calcium, phosphate, alkaline phosphatase (ALP), parathyroid hormone (PTH), and BMD from baseline to post-treatment course of denosumab in ESRD patients. Study results were pooled and analyzed using a random-effect model. The protocol for this meta-analysis is registered with PROSPERO (International Prospective Register of Systematic Reviews; no. CRD42017081074). Six observational studies with a total of 84 ESRD patients were enrolled. The pooled estimated incidence of hypocalcemia during denosumab treatment was 42% (95% CI 29-55%, I2 = 0%). Hypocalcemia occurred approximately 7 to 20 days after the first dose and reached nadir of low calcium levels in the first 2 weeks up to 2 months. However, there were no significant changes in serum calcium or phosphate from baseline to post-treatment course (≥ 3 months after treatment) with mean differences [MDs] of 0.20 mg/dL (95% CI, - 0.30 to 0.69 mg/dL) and - 0.10 mg/dL (95% CI, - 0.70 to 0.49 mg/dL). There were significant reductions in ALP and PTH levels with standardized mean differences (SMDs) of - 0.65 (95% CI - 1.13 to - 0.16) and - 1.89 (95% CI - 3.44 to - 0.34), respectively. There were significant increases in T-scores with MDs of 0.39 (95% CI 0.10 to 0.69) and 0.79 (95% CI 0.60 to 0.98) for lumbar spine and femoral neck, respectively. Our study demonstrates the estimated incidence of denosumab-associated hypocalcemia in dialysis patients of 42%. From baseline to post-treatment course, although there are no differences in serum calcium and phosphate, our findings suggest significant reductions in ALP and PTH and a significant increase in BMD. Currently, denosumab should not be considered as the treatment of choice in ESRD patients until more safety and efficacy data are available.

Abstract
Context Acetyl-l-carnitine (ALC), a mitochondrial carrier involved in lipid oxidation and glucose metabolism, decreased systolic blood pressure (SBP), and ameliorated insulin sensitivity in hypertensive nondiabetic subjects at high cardiovascular risk. Objective To assess the effects of ALC on SBP and glycemic and lipid control in patients with hypertension, type 2 diabetes mellitus (T2D), and dyslipidemia on background statin therapy. Design After 4-week run-in period and stratification according to previous statin therapy, patients were randomized to 6-month, double-blind treatment with ALC or placebo added-on simvastatin. Setting Five diabetology units and one clinical research center in Italy. Patients Two hundred twenty-nine patients with hypertension and dyslipidemic T2D >40 years with stable background antihypertensive, hypoglycemic, and statin therapy and serum creatinine <1.5 mg/dL. Interventions Oral ALC 1000 mg or placebo twice daily on top of stable simvastatin therapy. Outcome and Measures Primary outcome was SBP. Secondary outcomes included lipid and glycemic profiles. Total-body glucose disposal rate and glomerular filtration rate were measured in subgroups by hyperinsulinemic–euglycemic clamp and iohexol plasma clearance, respectively. Results SBP did not significantly change after 6-month treatment with ALC compared with placebo (−2.09 mm Hg vs −3.57 mm Hg, P = 0.9539). Serum cholesterol, triglycerides, and lipoprotein(a), as well as blood glucose, glycated hemoglobin, fasting insulin levels, homeostatic model assessment of insulin resistance index, glucose disposal rate, and glomerular filtration rate did not significantly differ between treatments. Adverse events were comparable between groups. Conclusions Six-month oral ALC supplementation did not affect blood pressure, lipid and glycemic control, insulin sensitivity and kidney function in hypertensive normoalbuminuric and microalbuminuric T2D patients on background statin therapy.

Abstract
Idiopathic normal pressure hydrocephalus (iNPH) is the most common cause of hydrocephalus in adults. The diagnosis may be challenging, requiring collaborative efforts between different specialists. According to the International Society for Hydrocephalus and Cerebrospinal Fluid Disorders, iNPH should be considered in the differential of any unexplained gait failure with insidious onset. Recognizing iNPH can be even more difficult in the presence of comorbid neurologic disorders. Among these, idiopathic Parkinson's disease (PD) is one of the major neurologic causes of gait dysfunction in the elderly. Both conditions have their peak prevalence between the 6th and the 7th decade. Importantly, postural instability and gait dysfunction are core clinical features in both iNPH and PD. Therefore, diagnosing iNPH where diagnostic criteria of PD have been met represents an additional clinical challenge. Here, we report a patient with parkinsonism initially consistent with PD who subsequently displayed rapidly progressive postural instability and gait dysfunction leading to the diagnosis of concomitant iNPH. In the following sections, we will review the clinical features of iNPH, as well as the overlapping and discriminating features when degenerative parkinsonism is in the differential diagnosis. Understanding and recognizing the potential for concomitant disease are critical when treating both conditions.

Abstract
BACKGROUND Rajyoga meditation is taught by Prajapita Brahmakumaris World Spiritual University (Brahmakumaris) and has been followed by more than one million followers across the globe. However, rare studies were conducted on physiological aspects of rajyoga meditation using electroencephalography (EEG). Band power and cortical asymmetry were not studied with Rajyoga meditators. AIMS This study aims to investigate the effect of regular meditation practice on EEG brain dynamics in low-frequency bands of long-term Rajyoga meditators. SETTINGS AND DESIGN Subjects were matched for age in both groups. Lower frequency EEG bands were analyzed in resting and during meditation. MATERIALS AND METHODS Twenty-one male long-term meditators (LTMs) and same number of controls were selected to participate in study as par inclusion criteria. Semi high-density EEG was recorded before and during meditation in LTM group and resting in control group. The main outcome of the study was spectral power of alpha and theta bands and cortical (hemispherical) asymmetry calculated using band power. STATISTICAL ANALYSIS One-way ANOVA was performed to find the significant difference between EEG spectral properties of groups. Pearson's Chi-square test was used to find difference among demographics data. RESULTS Results reveal high-band power in alpha and theta spectra in meditators. Cortical asymmetry calculated through EEG power was also found to be high in frontal as well as parietal channels. However, no correlation was seen between the experience of meditation (years, hours) practice and EEG indices. CONCLUSION Overall findings indicate contribution of smaller frequencies (alpha and theta) while maintaining meditative experience. This suggests a positive impact of meditation on frontal and parietal areas of brain, involved in the processes of regulation of selective and sustained attention as well as provide evidence about their involvement in emotion and cognitive processing.

Abstract
A 42-year-old hypothyroid shepherd presented with a progressive abdominal lump accompanied by nausea and abdominal fullness. In addition, he had worsening hypothyroidism, despite supranormal doses of thyroxine. Computed tomography of the abdomen was suggestive of a mass lesion in relation to the stomach. A resection of the mass was done and the histopathology was suggestive of gastrointestinal stromal tumor. After surgery, the patient became euthyroid. We believe the patient had consumptive hypothyroidism due to the tumor.

Abstract
Meditation has a versatile nature to affect cognitive functioning of human brain. Recent researches demonstrated its effects on white matter (WM) properties of human brain. In this research, we aim to investigate WM microstructure of corpus callosum (CC) in long-term meditators (LTMs) of rajayoga meditation using diffusion tensor imaging. For this cross-sectional analysis, 22 LTMs and 17 control participants of age ranging from 30 to 50 years were recruited. Results show high fractional anisotropy values with low mean diffusivity in whole as well as different segments of CC in the LTM group. Also the experience of meditation was correlated with WM properties of CC tracts. Findings may suggest rajayoga meditation to bring potential changes in microstructure of CC segments. Further studies are suggested in clinical population to check its validity and efficacy against disorders involving agenesis of WM.

Abstract
PurposeTimely diagnosis of intraocular tuberculosis (IOTB) along with detection of drug resistance can save many eyes from visual impairment. With the growing incidence of IOTB and rising drug resistance, a reliable diagnostic platform for simultaneous detection of the agent and mutated gene is urgently needed. The MTBDRplus assay was evaluated directly on vitreous fluid samples for the same.Patients and methodsIn a prospective study, The MTBDRplus assay was performed on 127 vitreous fluid samples (77 'study group' comprising cases of presumed ocular tuberculosis and 50 'control group' cases of disease controls (n=25) and non-uveitic controls (n=25)). All samples positive by MTBDRplus assay were subjected to gene sequencing to confirm the mutations for rifampicin and isoniazid resistance.ResultsThe MTBDRplus assay produced a sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 36.36%, 100%, 100%, and 50.50%, respectively, for the detection of IOTB. Among the 28 cases from study group that were positive by MTBDRplus assay, rifampicin resistance was reported in six and isoniazid resistance in two cases. On sequencing of rpoB and katG gene, one case of false rifampicin-resistant by MTBDRplus was found. The other resistant isolates showed concordant mutations between MTBDRplus assay and sequencing.ConclusionThe MTBDRplus assay is an effective tool for the rapid diagnosis of IOTB along with detection of drug resistance, thereby improving the outcome in IOTB.

Sharma K, Halandras P, Milner R. Atypical Presentation of a Type 2 Endoleak following Emergency Open Repair of a Ruptured Abdominal Aortic Aneurysm. EJVES Short Rep 2017; 33:24-26. [PMID: 28856320 PMCID: PMC5576093 DOI: 10.1016/j.ejvssr.2016.09.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2016] [Revised: 09/05/2016] [Accepted: 09/07/2016] [Indexed: 11/17/2022] Open
Abstract
Background An endoleak is a common complication following EVAR. Specifically, a Type 2 endoleak occurs because of retrograde flow from lumbar vessels outside the endograft within the aneurysm sac. Even though it is common following EVAR, it has not been identified as a complication following open ruptured abdominal aortic aneurysm (AAA) repair. Report A 73-year-old male underwent open repair of a ruptured AAA. Five months later, computed tomography revealed filling from a lumbar vessel mimicking a Type 2 “endoleak.” The initial ultrasound showed a single pair of lumbar vessels with aneurysm sac expansion 8 weeks later. The “endoleak” and expanding sac were treated, and the 2-year surveillance demonstrated sac shrinkage. Discussion Because endoleak is a complication after EVAR, this case provides a unique presentation of Type 2 “endoleak” physiology following open repair of a ruptured AAA. It is believed that it is necessary to expand the list of possible complications after open ruptured AAA repair to include “endoleaks.” An endoleak is a common complication observed after EVAR, but not open AAA repair. Type 2 endoleak after open AAA repair has a similar treatment paradigm to EVAR. Translumbar embolization done utilized bony landmarks without endograft as landmark. Endoleak is a complication of EVAR, but open AAA repair can mimic similar pathology.
