Association between lung function and dyspnoea and its variation in the multinational Burden of Obstructive Lung Disease (BOLD) study. Pulmonology 2024:S2531-0437(24)00044-8. [PMID: 38614859 DOI: 10.1016/j.pulmoe.2024.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 03/14/2024] [Accepted: 03/31/2024] [Indexed: 04/15/2024] Open
Abstract
BACKGROUND Dyspnoea is a common symptom of respiratory disease. However, data on its prevalence in general populations and its association with lung function are limited and are mainly from high-income countries. The aims of this study were to estimate the prevalence of dyspnoea across several world regions, and to investigate the association of dyspnoea with lung function. METHODS Dyspnoea was assessed, and lung function measured in 25,806 adult participants of the multinational Burden of Obstructive Lung Disease study. Dyspnoea was defined as ≥2 on the modified Medical Research Council (mMRC) dyspnoea scale. The prevalence of dyspnoea was estimated for each of the study sites and compared across countries and world regions. Multivariable logistic regression was used to assess the association of dyspnoea with lung function in each site. Results were then pooled using random-effects meta-analysis. RESULTS The prevalence of dyspnoea varied widely across sites without a clear geographical pattern. The mean prevalence of dyspnoea was 13.7 % (SD=8.2 %), ranging from 0 % in Mysore (India) to 28.8 % in Nampicuan-Talugtug (Philippines). Dyspnoea was strongly associated with both spirometry restriction (FVC CONCLUSION The prevalence of dyspnoea varies substantially across the world and is strongly associated with lung function impairment. Using the mMRC scale in epidemiological research should be discussed.

Significant enhancement in the cold emission characteristics of chemically synthesized super-hydrophobic zinc oxide rods by nickel doping. NANOSCALE ADVANCES 2023; 5:6944-6957. [PMID: 38059027 PMCID: PMC10696928 DOI: 10.1039/d3na00776f] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 10/28/2023] [Indexed: 12/08/2023]
Abstract
The current article presents a huge enhancement in the field emission characteristics of zinc oxide (ZnO) micro/nanorods by nickel doping. The synthesis of pure and nickel-doped zinc oxide (ZnO) micro/nanorods was done by a simple low-temperature chemical method. Both the as-prepared pure and doped samples were analyzed by X-ray diffraction and electron microscopy to confirm the proper phase formation and the developed microstructure. UV-vis transmittance spectra helped in determining the band gap of the samples. Fourier-Transform Infrared Spectroscopy (FTIR) spectra showed the different bonds present in the sample, whereas X-ray Photoelectron Spectroscopy (XPS) confirmed the presence of nickel in the doped sample. Photoluminescence (PL) spectra showed that after doping, the band-to-band transition was affected, whereas defect-induced transition had increased significantly. After the nickel doping, contact angle measurement revealed a significant decrease in the sample's surface energy, leading to a remarkably high water contact angle (within the superhydrophobic region). Simulation through ANSYS suggested that the doped sample has the potential to function as an efficient cold emitter, which was also verified experimentally. The cold emission characteristics of the doped sample showed a significant improvement, with the turn-on field (corresponding to J = 1 μA cm-2) reduced from 5.34 to 2.84 V μm-1. The enhancement factor for the doped sample reached 3426, approximately 1.5 times higher compared to pure ZnO. Efforts have been made to explain the results, given the favorable band bending as well as the increased number of effective emission sites.

Search for Subsolar-Mass Binaries in the First Half of Advanced LIGO's and Advanced Virgo's Third Observing Run. PHYSICAL REVIEW LETTERS 2022; 129:061104.

Abstract
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 M_{⊙} and 1.0 M_{⊙} in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC. We extend our previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio q≥0.1. We do not report any gravitational-wave candidates. The most significant trigger has a false alarm rate of 0.14 yr^{-1}. This implies an upper limit on the merger rate of subsolar binaries in the range [220-24200] Gpc^{-3} yr^{-1}, depending on the chirp mass of the binary. We use this upper limit to derive astrophysical constraints on two phenomenological models that could produce subsolar-mass compact objects. One is an isotropic distribution of equal-mass primordial black holes. Using this model, we find that the fraction of dark matter in primordial black holes in the mass range 0.2 M_{⊙}<m_{PBH}<1.0 M_{⊙} is f_{PBH}≡Ω_{PBH}/Ω_{DM}≲6%. This improves existing constraints on primordial black hole abundance by a factor of ∼3. The other is a dissipative dark matter model, in which fermionic dark matter can collapse and form black holes. The upper limit on the fraction of dark matter black holes depends on the minimum mass of the black holes that can be formed: the most constraining result is obtained at M_{min}=1 M_{⊙}, where f_{DBH}≡Ω_{DBH}/Ω_{DM}≲0.003%. These are the first constraints placed on dissipative dark models by subsolar-mass analyses.

Abstract
UNLABELLED The incident of End stage renal disease (ESRD) is rising rapidly worldwide. Renal transplant is the best modality of treatment, offering a better quality of life and mortality benefit, as compared with long-term dialysis. Very few patients have a live renal transplant donor, for rest, a decreased donor renal transplant is the only alternative. Deceased donor renal transplantation (DDRT) programs are only available at few government centers of India, constituting less than 5% of the total renal transplants. MATERIAL The patients who had undergone DDRT at our center from February 2015 to February 2021 were registered in the study. The following data were recorded for all patients; age, sex, duration of ESRD, cold ischemia time, type of induction, nadir and follow -up creatinine, hemoglobin, urinary protein and complications. All recipients were followed up and investigated in the outpatient department on a regular basis as per the standard guidelines till death or graft loss, whichever is earlier. Post transplant renal allograft function was measured using serum creatinine and other parameters. OBSERVATION During the study period 51 DDRTs were done. There were 40 male and 11 female patients. The mean age was 39.9 ± 9.8 years. The most common cause of ESRD in recipients was chronic glomerulonephritis (CGN) in 92.1 % (47). Amongst the patients, 41 (80.3%) survived, while 10 (19.6%) died post-transplant. Out of ten, 6 recipients died due to early sepsis (<3 months) and 4 died due to late sepsis (>3 months). Acute rejection was present in 17.6 % of patients. Mean post- transplant creatinine in recipients with functioning graft at discharge was 1.54 mg/dl. Graft failure was present in 7 patients out of which 2 were alive at the time of writing this paper and were on maintenance dialysis. Two patients died with a functioning graft. Delayed graft function (DGF) was seen in 13.7% (n=7) of recipients. The causes of DGF in our study included transplant renal artery thrombosis (n=2), Antibody-Mediated Rejection (n=3), mixed rejection (n=1) and Acute cellular rejection (n=1). Among those who had DGF, graft loss was seen in 57.2% (n=4). CONCLUSION In our study, the patient survival and graft survival have been better as compared to previous studies and also the number of recipients with delayed graft function have been low. Deceased donor renal transplantation is a practical treatment modality which can drastically improve longevity and quality of life.

Sex hormones regulate metainflammation in diet-induced obesity in mice. J Biol Chem 2021; 297:101229.

Abstract
Men have a statistically higher risk of metabolic and cardiovascular disease than premenopausal women, but the mechanisms mediating these differences are elusive. Chronic inflammation during obesity contributes to disease risk and is significantly more robust in males. Prior work demonstrated that compared with obese males, obese females have reduced proinflammatory adipose tissue macrophages (ATMs). Given the paucity of data on how sex hormones contribute to macrophage responses in obesity, we sought to understand the role of sex hormones in promoting obesity-induced myeloid inflammation. We used gonadectomy, estrogen receptor-deficient alpha chimeras, and androgen-insensitive mice to model sex hormone deficiency. These models were evaluated in diet-induced obesity conditions (high-fat diet [HFD]) and in vitro myeloid assays. We found that ovariectomy increased weight gain and adiposity. Ovariectomized females had increased ATMs and bone marrow myeloid colonies compared with sham-gonadectomized females. In addition, castrated males exposed to HFD had improved glucose tolerance, insulin sensitivity, and adiposity with fewer Ly6chi monocytes and bone marrow myeloid colonies compared with sham-gonadectomized males, although local adipose inflammation was enhanced. Similar findings were observed in androgen-insensitive mice; however, these mice had fewer CD11c+ ATMs, implying a developmental role for androgens in myelopoiesis and adipose inflammation. We concluded that gonadectomy results in convergence of metabolic and inflammatory responses to HFD between the sexes, and that myeloid estrogen receptor alpha contributes minimally to diet-induced inflammatory responses, whereas loss of androgen-receptor signaling improves metabolic and inflammatory outcomes. These studies demonstrate that sex hormones play a critical role in sex differences in obesity, metabolic dysfunction, and myeloid inflammation.

Abstract
INTRODUCTION Otolaryngology health personnel are at high risk of acquiring COVID-19 disease and, hence, are likely to have high stress levels. This study was designed to evaluate the feedback of otolaryngology healthcare workers in ENT departments who are managing patients in the coronavirus pandemic. METHODS A questionnaire focused on all aspects of healthcare delivery was completed by otolaryngology healthcare workers. RESULTS The findings, based on statistical analyses, included high stress levels and inadequate disease-related information in these workers. CONCLUSIONS Healthcare authorities need to take care of issues related to mental health in healthcare professionals in addition to spreading awareness about safe practices. Further studies are needed to continuously monitor feedback from personnel as the coronavirus pandemic unravels in the future.

Abstract
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks, and, for the first time, kink-kink collisions. A template-based search for short-duration transient signals does not yield a detection. We also use the stochastic gravitational-wave background energy density upper limits derived from the O3 data to constrain the cosmic string tension Gμ as a function of the number of kinks, or the number of cusps, for two cosmic string loop distribution models. Additionally, we develop and test a third model that interpolates between these two models. Our results improve upon the previous LIGO-Virgo constraints on Gμ by 1 to 2 orders of magnitude depending on the model that is tested. In particular, for the one-loop distribution model, we set the most competitive constraints to date: Gμ≲4×10^{-15}. In the case of cosmic strings formed at the end of inflation in the context of grand unified theories, these results challenge simple inflationary models.

Abstract
Complete surgical resection of a giant solitary fibrous tumour of the pleura can be challenging. We describe our technique for dealing with one such tumour. A clamshell incision proved inadequate for visualising the extent of the tumour. An additional lower sternotomy incision was then made, which significantly improved exposure. With the aid of cardiopulmonary bypass, it was then possible to mobilise and completely excise the tumour. Complete resection remains the mainstay of treatment for such pleural-based tumours. Every attempt must be made to achieve this, including any modification of the traditional approach if required.

Inflammatory responses to dietary and surgical weight loss in male and female mice. Biol Sex Differ 2019; 10:16.

Abstract
BACKGROUND Weight loss by surgery or lifestyle changes is strongly recommended for obese individuals to improve metabolic health, but the underlying impairments that persist from a history of obesity remain unclear. Recent investigations demonstrate a persistent inflammatory state with weight loss and bariatric surgery, but the mechanism and impact are not fully understood. Additionally, these studies have not been performed in females although women are the majority of individuals undergoing weight loss interventions. METHODS The goal of this study was to determine the sex differences in metabolically induced inflammation after dietary weight loss (WL) or bariatric surgery. Following a 60% high-fat diet (HFD) for 12 weeks, C57Bl/6j mice underwent either a dietary switch to normal chow for WL or vertical sleeve gastrectomy (VSG) and were evaluated 8 weeks after intervention. WL effects on myelopoiesis were further evaluated with bone marrow chimeras. RESULTS Both sexes had a decrease in adiposity and total weight following WL or VSG intervention. With HFD, females had very little inflammation and no further increase with WL, but males had persistent inflammation even after WL despite metabolic improvement. Interestingly, after VSG, myeloid inflammation was increased in the livers of males and to a lesser extent in females. CONCLUSIONS These studies demonstrate that regardless of sex, it is critical to assess an individuals' history of obesity rather than just rely on current weight status in medical decision-making. There are long-lasting effects on tissue inflammation in both sexes especially with surgical weight loss. Dietary change is overall most effective to improve meta-inflammation in obese males on its own or in combination with surgical weight loss.

Abstract
INTRODUCTION Overall complication rates associated with a wide range of diagnostic and therapeutic interventional cardiac procedures in a contemporary academic setting have not been reported. ANIMALS, MATERIALS AND METHODS Consecutive interventional procedures performed for client-owned dogs were retrospectively analyzed to characterize procedural complications and mortality. RESULTS Three hundred sixty-four procedures were performed on 336 dogs. Interventions included attempted or completed transvenous pacemaker (PM) implantation (n = 134) with subsequent pacing system revision (n = 8), pulmonic balloon valvuloplasty (BVP) (n = 117) with a subset of patients undergoing an additional BVP (n = 14), transarterial closure of left-to-right shunting patent ductus arteriosus (PDA) (n = 66), diagnostic angiography and/or cardiovascular pressure measurement (n = 9), transvenous temporary pacing (n = 7), septal defect occlusion (n = 5), heartworm extraction (n = 3), and BVP catheter fragment retrieval (n = 1). The prevalence of major perioperative and postoperative complications for all procedures was 5% and 6%, respectively, and the procedural mortality rate was 2%. The overall rate of major complications was 12% for the PM group, 11% for the BVP group, and 2% for the PDA occlusion group. Both PM implantation and BVP have higher rates of major complications overall compared with PDA occlusion (p=0.0151). CONCLUSIONS The results of this study indicate that the prevalence of major complications and mortality associated with interventional cardiac procedures is low; however, significant differences exist in complication rates between procedures.

Sex Differences in Inflammatory Responses to Adipose Tissue Lipolysis in Diet-Induced Obesity. Endocrinology 2019; 160:293-312.

Abstract
Males are known to have profound adipose tissue macrophage (ATM) accumulation in gonadal white adipose tissue (GWAT) during obesity, whereas females are protected from such an inflammatory response even with increased adiposity. The inflammatory tone in males is linked to insulin resistance and might be the underlying cause for sex differences in metabolic disease. Factors regulating the meta-inflammatory response remain unclear but enhanced lipid storage in females may explain the reduced inflammatory response to high-fat diets. In this study, we evaluated lean and obese females with stimulated lipolysis to understand whether a stress release of free fatty acids (FFAs) could induce female ATMs. We demonstrate that in both lean and obese females, GWAT CD11c- resident ATMs accumulate with β-3 adrenergic receptor-stimulated lipolysis. Lipolysis elevated serum FFA, triglyceride, and IL-6 levels in females that corresponded to significant phosphorylated hormone-sensitive lipase and adipose triglyceride lipase protein expression in obese female GWAT compared with males. Increased lipolytic response in obese females was associated with crown-like structures and induced Il6, Mcp1, Arg1, and Mgl1 expression in obese female GWAT, suggesting an environment of lipid clearance and adipose remodeling. With this finding we next investigated whether lipid storage and lipolytic mediators differed by sex. Diacylglycerol, ceramides, phospholipids, and certain fatty acid species associated with inflammation were elevated in male GWAT compared with obese female GWAT. Overall, our data demonstrate a role for GWAT lipid storage and lipolytic metabolites to induce inflammation in males and induce remodeling in females that might explain sex differences in overall metabolic health.

The association of hypotension during non-cardiac surgery, before and after skin incision, with postoperative acute kidney injury: a retrospective cohort analysis. Anaesthesia 2018; 73:1223-1228.

Abstract
Intra-operative hypotension is associated with acute postoperative kidney injury. It is unclear how much hypotension occurs before skin incision compared with after, or whether hypotension in these two periods is similarly associated with postoperative kidney injury. We analysed the association of mean arterial pressure < 65 mmHg with postoperative kidney injury in 42,825 patients who were anaesthetised for elective non-cardiac surgery. Intra-operative hypotension occurred in 30,423 (71%) patients: 22,569 (53%) patients before skin incision; and 24,102 (56%) patients after incision. Anaesthetised patients who were hypotensive had mean arterial pressures < 65 mmHg for a median (IQR [range]) of 5.5 (0.0-14.7 [0.0-60.0]) min.h-1 before skin incision, compared with 1.7 [0.3-5.1 [0.0-57.5]) min.h-1 after incision: a median (IQR [range]) of 36% (0%-84% [0%-100%]) of hypotensive readings were before incision. We diagnosed postoperative kidney injury in 2328 (5%) patients. The odds ratio (95%CI) for acute kidney injury was 1.05 (1.02-1.07) for each doubling of the duration of hypotension, p < 0.001. Postoperative kidney injury was associated with the product of hypotension duration and severity, that is, area under the curve, before skin incision and after, odds ratio (95%CI): 1.02 (1.01-1.04), p = 0.004; and 1.02 (1.00-1.04), p = 0.016, respectively. A substantial fraction of all hypotension happened before surgical incision and was thus completely due to anaesthetic management. We recommend that anaesthetists should avoid mean arterial pressure < 65 mmHg during surgery, especially after induction, assuming that its association with postoperative kidney injury is, at least in part, causal.

Abstract
The aim of this study was to measure insulin resistance (IR) in dialysis patients and its relation to Vitamin D status and nutritional parameters. We included patients on maintenance dialysis, both hemodialysis and peritoneal dialysis (HD and PD). IR was measured by homeostatic model assessment (HOMA)-IR index defined as fasting serum insulin (μU/L) × fasting blood sugar (mmol/L)/22.5. Baseline Vitamin D levels were measured by chemiluminescence immunoassay (CLIA) method. HOMA-IR index correlated with nutritional parameters such as 7-point subjective global assessment (SGA) and anthropometric measures, for example, body fat percentage, lean body weight (LBW), mid-arm circumference (MAC), and mid-arm muscle circumference (MAMC). A total of 55 patients were studied, of them 74.55% were male with mean age of the study population being 37.44 ± 14.96 years. The prevalence values of Vitamin D deficiency <30 ngm/ml, <20 ngm/ml, and <10 ngm/ml levels were 96.36%, 70.91%, and 23.64%, respectively. Mean HOMA-IR index was 3.14 ± 3.86. The correlation of HOMA-IR with Vitamin D was negative (r = -0.140, 95% confidence interval [CI] = -0.397-0.138 and P = 0.309); however, in subgroup analysis, patients with Vitamin D level <20 ng/ml had significantly high IR compared to those with Vitamin D >20 ng/ml, i.e., 3.74 ± 4.37 and 1.67 ± 1.47, respectively (P = 0.018). The other measured parameter which had a significant positive correlation with IR was serum uric acid (r = 0.303, 95% CI = 0.021-0.534, and P = 0.025). In nutritional assessment, body mass index, MAC, and MAMC had statistically significant positive correlation with HOMA-IR index (P ≤ 0.001, 0.004, and 0.004, respectively) unlike SGA (P = 0.480). The mode of dialysis did not have a significant effect on IR (HD vs. PD, P = 0.227). The majority of the patients on maintenance dialysis are Vitamin D deficient. Low Vitamin D level, especially <20 ng/ml, muscle mass, and high serum uric acid level are likely to have more IR in dialysis-dependent patients.

Abstract
Backgound and Aim: The best test to guide the choice of systemic therapy for breast cancer (BC) has not yet been identified. We did this study to identify factors that drive proliferation features in BC and assess their association with clinical outcomes after systemic therapy.
Methods: We applied an artificial neural network-based integrative data mining approach to three cohorts of patients with untreated lymph node (LN)-negative BC (Wang et al; n=286, Desmedt et al; n=198 and Schmidt et al; n=200). The results were validated in four cohorts of BC patients (the Nottingham discovery cohort (n=171), Uppsala cohort (n=249), The Cancer Genome Atlas-Breast Cancer project [TCGA-BRCA; n= 970] and Molecular Taxonomy of Breast Cancer International Consortium [METABRIC cohort; n=1980]. Genes that featured prominently in our interactome map of proliferation have been chosen to take them forward to investigate their clinicopathological relevance of their gene copy number aberrations (CNAs), mRNA transcript expression, and protein expression and their associations with breast cancer-specific survival (BCSS), distant relapse-free survival (DRFS) and pathological complete response (pCR) in ten international cohorts of BC (n>12000 patients).
Findings: ESR1, SPAG5, EGFR, BCL2, and FOXA1 were among the 39 common gene probes that were predictive across most proliferation features and datasets. In TCGA-BRCA cohort, SPAG5 gene mutation, gain/amplification and loss at the Ch17q11.2 locus were detected in 43 (4.4%), 177 (18.2%) and 180 (18.8%) of 970 patients, respectively and 65 (31%) of 479 ER-positive /HER-positive patients showed gain/amplification of SPAG5 gene. In multivariable analysis, high SPAG5 transcript and SPAG5 protein expression were associated with reduced BCSS compared with lower expression (METABRIC: HR 1·27, 95% CI 1·02–1·58, p=0·034; untreated LN-negative cohort: 2·34, 1·24–4·42, p=0·0090; and Nottingham-cohort: 1·73, 1·23–2·46, p=0·0020). In patients with ER-negative/HER2-negative or ER-positive/HER2-negative BC, high SPAG5 transcript expression was associated with an increased pCR compared with low SPAG5 transcript expression after receiving anthracycline neoadjuvant chemotherapy (AC-NeoACT) [(Multicentre phase 2 clinical trial cohort; n=136; OR 2·47, 95% CI 1·17–5·21, p=0.016) and (MD Anderson- taxane+AC-NeoACT cohort; n=287; OR 3·16, 95% CI 1·46–6·84, p=0.003); respectively]. In patients with ER-positive/HER2-negative BC who received taxane+AC-NeoACT followed by adjuvant tamoxifen (Adj-Tam) for 5 years (MD Anderson- taxane+AC-NeoACT cohort; n=287), high and low SPAG5 transcript expression had similar DRFS (HR 1·40, 95% CI 0.76–2·58, p=0.282). Whereas in ER-positive/HER2-negative BC patients who received only adj-Tam (n=298), high SPAG5 transcript expression was associated with reduced DRF at 5 years compared with lower expression (HR 1.98, 95% CI 1.19–3.27, p=0.008).
Interpretation: The transcript and protein products of SPAG5 are independent prognostic and predictive biomarkers that might have clinical utility as biomarkers for combination cytotoxic chemotherapy sensitivity in ER-positive/HER-negative BC.

Abstract
Effect of cryogenic grinding on recovery of volatile oil, fatty oil percentage and their constituents in two cumin (Cuminum cyminum L.) genotypes have been analyzed. Cryogenic grinding not only retains the volatiles but enhanced the recovery by 33.9 % in GC 4 and 43.5 % in RZ 209. A significant increase (29.9 %) over normal grinding in oil percentage was also observed in genotype RZ 209. This increase was, however, less (15.4 %) in genotype GC 4. Nineteen major compounds were identified in the essential oil of both genotypes. The two grinding techniques had significant effects on dependent variables, viz., volatile oil and monoterpenes. Cuminaldehyde was the main constituent in both genotypes, content of which increased from 48.2 to 56.1 % in GC 4 on cryo grinding. Content of terpines were found to decrease in cryo ground samples of GC 4 and either decrease or no change was found in RZ 209. Organoleptic test showed more pleasant aroma in cryo ground seeds of both the genotypes. Significant increase was also reported in fatty oil yield due to cryogenic grinding. Fatty acid methyl ester (FAME) analysis showed oleic acid as major FAME content of which increased from 88.1 to 94.9 % in RZ 209 and from 88.2 to 90.1 % in GC 4 on cryogenic grinding. Other prominent FAME were palmitic, palmitoleic and stearic acid. Results indicated commercial potential of cryogenic grinding technology for cumin in general and spices in particular for better retention of flavour and quality in spices.

Abstract
The efficacy of phenylephrine might be improved by giving doses higher than that traditionally used (100 µg). This study compared the effects of three initial bolus doses of intravenous phenylephrine; 100 µg (group P100), 125 µg (group P125) and 150 µg (group P150), for the treatment of post-spinal hypotension in patients undergoing elective caesarean delivery. If hypotension was not corrected by this dose, additional boluses of 25 µg were given every minute. Further hypotensive episodes were treated with half the initial bolus dose, followed by 25 µg boluses, as required. Umbilical arterial and venous blood samples were obtained for blood gas analysis and Apgar scores recorded. One hundred and twenty subjects (40 per group) who developed post-spinal hypotension (75%) were included in this randomised, double blind trial. Although systolic blood pressure was higher at certain time-points after 150 µg phenylephrine, there were no statistically significant differences in the effectiveness of the first bolus of phenylephrine to treat hypotension (85%, 95% and 95% in groups P100, P125 and P150, respectively, P=0.215); the additional dose of phenylephrine after the first bolus (P=0.810); the number of additional boluses (P=0.318) or of hypotensive episodes (P=0.118). There were no significant differences in the number of patients developing reactive hypertension or bradycardia, in maternal side-effects or in neonatal outcomes. Although the study may have been underpowered, initial phenylephrine bolus doses of 100 µg, 125 µg and 150 µg did not significantly differ in efficacy to treat post-spinal hypotension in these patients.

Abstract
C3 glomerulopathy has recently been described as a distinct entity. The underlying mechanism is unregulated activation of the alternate pathway of the complement system. The most common presentation is with an acute nephritic syndrome. The diagnosis is made on immunofluoroscence by the presence of isolated or dominant C3 staining. In this retrospective study, renal biopsy data were collected from 2010 to 2013 patients with C3 glomerulopathy identified and their clinical and biochemical parameters analyzed. Out of 514 biopsies available for analysis, the incidence of C3 glomerulopathy was 1.16% (n = 6). The mean age of the presentation was 26 years and the average estimated glomerular filtration rate was 30.65 ml/min/1.73 m(2). The most common histopathological pattern was membranoproliferative glomerulonephritis (n = 4).

Abstract
BACKGROUND Anaemia is highly prevalent among pregnant women and iron deficiency is the most important cause. Like many other countries, India has policies to give pregnant women iron supplements. Non-compliance is one important challenging factor in combating anaemia. OBJECTIVE To estimate the compliance for IFA tablets among pregnant women and to study the social factors influencing it. METHODOLOGY This study included 190 pregnant women seeking ante-natal care in tertiary health Centres in the Mangalore city in South India. After Institutional Ethics Committee (IEC) approval, data was collected by personal interview. Missing ≥2 doses consecutively was considered non-compliance. The data was analyzed using SPSS (Statistical Package for Social Sciences) version 11.5. RESULTS The mean age of the study population was 25.8 years (SD: 4.1). Majority of the subjects consumed mixed diet and 72.1% belonged to lower socioeconomic status. Overall, compliance with IFA tablets was 64.7%. Compliance increased with the increase in age, birth order and single daily dose. Forgetfulness and both perceived as well as experienced side effects of IFA therapy were the important factors for non-compliance. CONCLUSION There was a moderate level of Compliance towards IFA tablets with key social and demographic factors playing important role.

Abstract
BACKGROUND Breast cancer is one of the most common malignancies in women. Genome-wide association studies have identified FGFR2 as a breast cancer susceptibility gene. Common variation in other fibroblast growth factor (FGF) receptors might also modify risk. We tested this hypothesis by studying genotyped single-nucleotide polymorphisms (SNPs) and imputed SNPs in FGFR1, FGFR3, FGFR4 and FGFRL1 in the Breast Cancer Association Consortium. METHODS Data were combined from 49 studies, including 53 835 cases and 50 156 controls, of which 89 050 (46 450 cases and 42 600 controls) were of European ancestry, 12 893 (6269 cases and 6624 controls) of Asian and 2048 (1116 cases and 932 controls) of African ancestry. Associations with risk of breast cancer, overall and by disease sub-type, were assessed using unconditional logistic regression. RESULTS Little evidence of association with breast cancer risk was observed for SNPs in the FGF receptor genes. The strongest evidence in European women was for rs743682 in FGFR3; the estimated per-allele odds ratio was 1.05 (95% confidence interval=1.02-1.09, P=0.0020), which is substantially lower than that observed for SNPs in FGFR2. CONCLUSION Our results suggest that common variants in the other FGF receptors are not associated with risk of breast cancer to the degree observed for FGFR2.

Abstract
Histoplasmosis is a progressive granulomatous disease caused by the intracellular dimorphic fungus Histoplasma capsulatum. We report a rare case of esophageal histoplasmosis in a renal allograft recipient. A 55-year-old male who received a live, unrelated renal allograft 20 years ago presented with complaints of recurrent fever for ten to 12 months, weight loss over six months, progressive dysphagia more for solids for five to six months and joint pain and swelling involving the bilateral metacarpo-phalangeal and proximal interphalangeal joints. Biopsy from the esophageal ulcers revealed dense inflammation infiltrated with lymphocytes and macrophages with clusters of strongly positive intracellular fungal spores with a clear area or "halo-like" zone suggestive of Histoplasma capsulatum invasion. The patient was treated with intravenous liposomal amphotericin B for ten days and later switched over to oral itraconazole. Repeated endoscopy revealed significant improvement of the lesions.

Abstract
This study compared the effects of intravenous infusions of phenylephrine and mephentermine on the prevention of maternal hypotension and neonatal outcome in patients receiving spinal anaesthesia for caesarean section. Sixty ASA 1-2 patients with term, uncomplicated singleton pregnancy undergoing caesarean section under spinal anaesthesia were randomly divided into two groups of 30 each, to receive a prophylactic intravenous infusion of either phenylephrine or mephentermine. The incidence of hypotension was statistically similar in the two groups. However, in patients receiving phenylephrine, 7 (23%) developed bradycardia and 6 (20%), reactive hypertension. Neonatal outcome, in terms of Apgar scores and umbilical artery pH, was similar in both the groups. To conclude, phenylephrine and mephentermine infusions are equally effective in preventing post spinal hypotension in patients undergoing caesarean section and are associated with a similar neonatal outcome.

METHODS Percuteneous balloon mitral valvuloplasty (BMV) was done in 145 cases of which 70patients had the history of previous surgical commissurotomy (Group I) and 75 patients were the new cases for the BMV (Group II). RESULTS In group I the age range was 35-65 years. In group I the duration of surgical commissurotomy (SC) was of 2-18 years past. In this group the result of balloon mitral valvuloplasty (BMV) was successful in 69 cases. Mitral valve area (MVA) before the procedure was 0.5-0.9 sq cm with mean 0.7 +/- 0.2 sq cm. Following procedure the MVA was 1.2-2.0 cm2 with a mean of 1.6 +/- 0.4 cm2. Mean gradient across mitral valve (MV) before the procedure was 15-25 mm of Hg with a mean 20 +/- 5 mm of Hg and after the procedure was 3-5 mm Hg with a mean of 4 +/- 1 mm Hg. In Group I, MVA > 1.8 cm2 was achieved in 25 cases & > 1.2-1.8 cm2 in 44 cases. Mitral regurgitation > or = grade 1 occurred in 8 cases (compared to previous echocardiography). In group II the age range was between 35-60 years. The result of BMV was successful in 74 cases. MVA before the procedure was 0.4-1.2 cm2 with a mean of 0.8 +/- 0.4 cm2. Following the procedure MVA was 1.3-2.1 cm2 with a mean of 1.7 +/- 0.4 cm2. Mean gradient across the mitral valve before the procedure was 15-29 mm of Hg with a mean of 22 +/- 7 mm of Hg. Mean gradient across the mitral valve after the procedure was 2-4 mm of Hg with a mean of 3 +/- 1 mm of Hg. MVA more than 1.8 cm2 was achieved in 29 cases and between 1.3-1.8 in 45 cases. CONCLUSION BMVin patients with mitral restenosis following Surgical mitral commissurtomy can be performed with almost similar success rate like that of BMV for the first time with low risk of major cardiac complication.

Abstract
There are a number of case reports describing accidental subdural block during the performance of subarachnoid or epidural anaesthesia. However, it appears that subdural drug deposition remains a poorly understood complication of neuraxial anaesthesia. The clinical presentation may often be attributed to other causes. Subdural injection of local anaesthetic can present as high sensory block, sometimes even involving the cranial nerves due to extension of the subdural space into the cranium. The block is disproportionate to the amount of drug injected, often with sparing of sympathetic and motor fibres. On the other hand, the subdural deposition can also lead to failure of the intended block. The variable presentation can be explained by the anatomy of this space. High suspicion in the presence of predisposing factors and early detection could prevent further complications. This review aims at increasing awareness amongst anaesthetists about inadvertent subdural block. It reviews the relevant anatomy, incidence, predisposing factors, presentation, diagnosis and management of unintentional subdural block during the performance of neuraxial anaesthesia.
