Vitamin B12 supplementation during pregnancy and postpartum improves B12 status of both mothers and infants but vaccine response in mothers only: a randomized clinical trial in Bangladesh. - European journal of nutrition
Poor vitamin B12 (B12) status is associated with adverse outcomes in pregnancy and infancy. Little is known about effects of B12 supplementation on immune function. The present study aimed to evaluate effects of pre- and postnatal B12 supplementation on biomarkers of B12 status and vaccine-specific responses in mothers and infants.In a blinded, placebo-controlled trial, Bangladeshi women (n = 68, age 18-35 years, hemoglobin <110 g/L, 11-14 weeks pregnant) were randomized to receive 250 μg/day B12 or a placebo throughout pregnancy and 3-month postpartum along with 60 mg iron + 400 μg folate. Women were immunized with pandemic influenza A (H1N1) vaccine at 26- to 28-week gestation. Blood from mothers (baseline, 72-h post-delivery, 3-month postpartum), newborns and infants (3-month) was analyzed for hemoglobin, B12, methylmalonic acid (MMA), total homocysteine (tHcy), ferritin and serum transferrin receptor, C-reactive protein (CRP) and alpha-1-acid glycoprotein (AGP). Vitamin B12 was also assessed in breast milk. H1N1-specific antibodies were determined in plasma and colostrum/breast milk.At baseline, 26 % women were B12 deficient (<150 pmol/L), 40 % had marginal status (150-220 pmol/L), 43 % had elevated MMA (>271 nmol/L), and 31 % had elevated tHcy (>10 μmol/L). Supplementation increased B12 in plasma, colostrums and breast milk (p < 0.05) and lowered MMA in neonates, mothers and infants at 3 months (p < 0.05). B12 supplementation significantly increased H1N1-specific IgA responses in plasma and colostrums in mothers and reduced proportion of infants with elevated AGP and CRP compared with placebo.Supplementation with 250 μg/day B12 during pregnancy and lactation substantially improved maternal, infant and breast milk B12 status. Maternal supplementation improved H1N1 vaccine-specific responses in mothers only and may alleviate inflammatory responses in infants.
Right ventricular perforation: a rare complication of pulmonary artery catheterization. - Journal of the College of Physicians and Surgeons--Pakistan : JCPSP
A 70 years old male underwent Coronary Artery Bypass and Graft (CABG) surgery. After induction, a Pulmonary Artery Catheter (PAC) was inserted via right IJV with some difficulty in achieving PA tracing. During distal RCA anastomosis, surgeon noticed PAC tip coming out of Right Ventricular (RV) surface. Resistance was felt on trying to pull PAC, so it was left there. Cardiac surgeon then opened the Right Atrium (RA) and pulled out the catheter. Multiple attempts during insertion of PA catheter should always raise the suspicion of PAC tip slipping back into the RV. It should be closely monitored during surgery and communicated to the surgeon.
Safety profile of fast-track extubation in pediatric congenital heart disease surgery patients in a tertiary care hospital of a developing country: An observational prospective study. - Journal of anaesthesiology, clinical pharmacology
Early extubation after cardiac operations is an important aspect of fast-track cardiac anesthesia. In order to reduce or eliminate the adverse effects of prolonged ventilation in pediatric congenital heart disease (CHD) surgical patients, the concept of early extubation has been analyzed at our tertiary care hospital. The current study was carried out to record the data to validate the importance and safety of fast-track extubation (FTE) with evidence.A total of 71 patients, including male and female aged 6 months to 18 years belonging to risk adjustment for congenital heart surgery-1 category 1, 2, and 3 were included in this study. All patients were anesthetized with a standardized technique and surgery performed by the same surgeon. At the end of operation, the included patients were assessed for FTE and standard extubation criteria were used for decision making.Of the total 71 patients included in the study, 26 patients (36.62%) were extubated in the operating room, 29 (40.85%) were extubated within 6 h of arrival in cardiovascular intensive care unit and 16 (22.54%) were unable to get extubated within 6 h due to multiple reasons. Hence, overall success rate was 77.47%. The reasons for delayed extubation were significant bleeding in 5 (31.3%) cases, hemodynamic instability (low cardiac output syndrome) in 4 (25%) cases, respiratory complication in 2 (12.5%), bleeding plus hemodynamic instability in 2 (12.5) cases, hemodynamic instability, and respiratory complication in 2 (12.5%) cases and triad of hemodynamic instability, bleeding and respiratory complication in 1 (6.5%) case. There was no reintubation in the FTE cases.On the basis of the current study results, it is recommended to use FTE in pediatric CHD surgical patients safely with multidisciplinary approach.
Comparison of efficacy of ondansetron and dexamethasone combination and ondansetron alone in preventing postoperative nausea and vomiting after laparoscopic cholecystectomy. - JPMA. The Journal of the Pakistan Medical Association
To compare the efficacy of ondansetron alone and combination of ondansetron and dexamethasone in preventing post-operative nausea and vomiting in patients undergoing laparoscopic cholecystectomy.The randomised control trial was conducted from April 23 to August 22, 2009, at the Liaquat National Hospital, Karachi, and comprised 100 American Society of Anaesthesiology I and II patients undergoing laparoscopic cholecystectomy. Half of the subjects comprised Group A and received ondansetron alone, while Group B received combination of ondansetron and dexamethasone. They were randomised by opaque envelope method. Group A received ondansetron 4 mg while Group B received ondansetron 4 mg with dexamethasone 8 mg, 1 minute before induction. Post-operatively patients were observed for six hours for any episode of nausea or vomiting, or whether the patients required any rescue anti emetic. SPSS 19 was used for statistical analysis.Patients receiving ondansetron alone showed 14 (28%) with incidence of nausea or vomiting while the other group showed 6 (12%). This difference was statistically significant (p < 0.046).Combination of ondansetron and dexamethasone was more efficacious compared to ondansetron alone in the prevention of postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy.
Endovascular repair of a large profunda femoris artery pseudoaneurysm. - Case reports in vascular medicine
Profunda femoris artery aneurysms and pseudoaneurysms are a rare cause of peripheral arterial aneurysms but their risk of rupture is quite high. We have presented a case of a left lower leg pseudoaneurysm. We have shown that endovascular repair with angioplasty and stenting is a suitable treatment method for such a pseudoaneurysm. Due to the limited data on this disease, we suggest multi-institute collaboration to identify and standardize management for the treatment.
Transatrial access for left atrial pressure (LAP) monitoring line placement in arterial switch operation (ASO) in neonates. - JPMA. The Journal of the Pakistan Medical Association
Left Atrial pressure monitoring is a useful and accurate method to guide Left ventricle filling in the patients who undergo Arterial switch operation for transposition of great arteries. We have used a different technique in three TGA patients for LA pressure monitoring line placement. After cleaning and draping,right internal jugular vein (rt IJV) located through 22G venous cannula, guide wire was put in followed by sliding the 22G x 8cm vygon arterial catheter over the guide wire into the right atrium that was directed transatrially into LA by the operating surgeon during atrial septum repair. The catheter was secured by silk on the neck and dressed with transparent dressing and was kept for a period of 48-72 hrs. LA pressure monitoring is helpful in anticipating LV dysfunction in ASO.
Arsenic exposure affects plasma insulin-like growth factor 1 (IGF-1) in children in rural Bangladesh. - PloS one
Exposure to inorganic arsenic (As) through drinking water during pregnancy is associated with lower birth size and child growth. The aim of the study was to assess the effects of As exposure on child growth parameters to evaluate causal associations.Children born in a longitudinal mother-child cohort in rural Bangladesh were studied at 4.5 years (n=640) as well as at birth (n=134). Exposure to arsenic was assessed by concurrent and prenatal (maternal) urinary concentrations of arsenic metabolites (U-As). Associations with plasma concentrations of insulin-like growth factor 1 (IGF-1), calcium (Ca), vitamin D (Vit-D), bone-specific alkaline phosphatase (B-ALP), intact parathyroid hormone (iPTH), and phosphate (PO4) were evaluated by linear regression analysis, adjusted for socioeconomic factor, parity and child sex. Child U-As (per 10 µg/L) was significantly inversely associated with concurrent plasma IGF-1 (β=-0.27; 95% confidence interval: -0.50, -0.0042) at 4.5 years. The effect was more obvious in girls (β=-0.29; -0.59, 0.021) than in boys, and particularly in girls with adequate height (β=-0.491; -0.97, -0.02) or weight (β=-0.47; 0.97, 0.01). Maternal U-As was inversely associated with child IGF-1 at birth (r=-0.254, P=0.003), but not at 4.5 years. There was a tendency of positive association between U-As and plasma PO4 in stunted boys (β=0.27; 0.089, 0.46). When stratified by % monomethylarsonic acid (MMA, arsenic metabolite) (median split at 9.7%), a much stronger inverse association between U-As and IGF-1 in the girls (β=-0.41; -0.77, -0.03) was obtained above the median split.The results suggest that As-related growth impairment in children is mediated, at least partly, through suppressed IGF-1 levels.
In utero arsenic exposure is associated with impaired thymic function in newborns possibly via oxidative stress and apoptosis. - Toxicological sciences : an official journal of the Society of Toxicology
Prenatal arsenic exposure is associated with increased infant morbidity and reduced thymus size, indicating arsenic-related developmental immunotoxicity. We aimed to evaluate effects of prenatal arsenic exposure on thymic function at birth and related mechanisms of action. In a Bangladeshi cohort, arsenic was measured in urine (U-As, gestational week (GW) 8 and 30) and blood (B-As, GW14) in 130 women. Child thymic index was measured by sonography at birth and thymic function by signal-joint T-cell receptor-rearrangement excision circles (sjTRECs) in cord blood mononuclear cells (CBMC). In a subsample (n = 44), sjTRECs content in isolated CD4(+) and CD8(+) T cells, expression of oxidative-stress defense and apoptosis-related genes in CBMC, arsenic concentrations (urine, placenta, and cord blood), and oxidative stress markers in placenta and cord blood were measured. In multivariable-adjusted regression, ln U-As (GW8) was inversely associated with ln sjTRECs in CBMC (B = -0.25; 95% confidence interval [CI] -0.48 to -0.01). Using multivariable-adjusted spline regression, ln U-As (GW30) and ln B-As (GW14) were inversely associated with ln sjTRECs in CBMC (B = -0.53; 95% CI -0.93 to -0.13 and B = -1.27; 95% CI -1.89 to -0.66, respectively) below spline knots at U-As 150 µg/l and B-As 6 µg/kg. Similar inverse associations were observed in separated CD4(+) and CD8(+) T cells. Arsenic was positively associated with 8-hydroxy-2'-deoxyguanosine in cord blood (B = 0.097; 95% CI 0.05 to 0.13), which was inversely associated with sjTRECs in CD4(+) and CD8(+) T cells. In conclusion, prenatal arsenic exposure was associated with reduced thymic function, possibly via induction of oxidative stress and apoptosis, suggesting subsequent immunosuppression in childhood.
Site selectively templated and tagged xerogels for chemical sensors. - Analytical chemistry
We report on a new sensor strategy that we have termed site selectively templated and tagged xerogels (SSTTX). The SSTTX platform is completely self-contained, and it achieves analyte recognition without the use of biomolecules. To illustrate the SSTTX scheme's potential, we present results for the selective detection and quantification of a model compound, 9-anthrol. The first-generation SSTTX shows the following: (i) exhibits an apparent dissociation constant of (1.8 +/- 0.3) x 10(-4) M for 9-anthrol; (ii) provides 0.3 muM detection limits for 9-anthrol; (iii) yields a 45-s response time (2-mum-thick film); (iv) is completely reversible (6% relative standard deviation after 25 cycles); (v) yields a selectivity factor for 9-anthrol over several structurally similar analogues/interferences (e.g., anthracene, 9,10-anthracenediol, benzophenone, 2-naphthol, phenol, and pyrene) of between 290 and 520; and (vi) is stable (<2% drift in performance) for at least 10 months when stored under ambient conditions in the dark. The results also suggest SSTTXs as new sensor elements for glycoside, pharmaceutical, prostaglandin, and steroid sensors.
Mechanistic studies of the tellurium(II)/tellurium(IV) redox cycle in thiol peroxidase-like reactions of diorganotellurides in methanol. - Journal of the American Chemical Society
Di-n-hexyl telluride (2), di-p-methoxyphenyl telluride (3), and (S)-2-(1-N,N-dimethylaminoethyl)phenyl phenyl telluride (4) catalyzed the oxidation of PhSH to PhSSPh with H(2)O(2) in MeOH. Telluride 2 displayed greater rate acceleration than the diaryltellurides 3 and 4 as determined by the initial velocities, v(0), for the rate of appearance of PhSSPh determined at 305 nm by stopped-flow spectroscopy. Rate constants for the oxidation of tellurides 2-4 (k(ox)), rate constants for the introduction of PhSH as a ligand to the Te(IV) center (k(PhSH)) of oxidized tellurides 5-7, and thiol-independent (k(1)) and thiol-dependent (k(2)) rate constants for reductive elimination at Te(IV) in oxidized tellurides 5-7 were determined using stopped-flow spectroscopy. Oxidation of the Te atom of the electron-rich dialkyl telluride 2 was more rapid than oxidation of diaryl tellurides 3 and 4. The dimethylaminoethyl substituent of 4, which acts as a chelating ligand to Te(IV), did not affect k(ox). Values of k(PhSH) for the introduction of PhSH to oxidized dialkyl tellurane 5 and oxidized diaryl tellurane 6 were comparable in magnitude, while the chelating dimethylaminoethyl ligand of oxidized telluride 7 diminished k(PhSH) by a fator of 10(3). Reductive elimination by both first-order, thiol-independent (k(1)) and second-order, thiol-dependent (k(2)) pathways was slower from dialkyl Te(IV) species derived from 2 than from diaryl Te(IV) species derived from 3. The chelating dimethylaminoethyl ligand of Te(IV) species derived from 4 diminished k(1) by a factor of 50 and k(2) by a factor of 3 (relative to the 3-derived species).
