Study Objective: Disparities in perinatal counseling among all pregnant women exist, yet teen data are lacking. We evaluated racial/ethnic differences in (1) prenatal and (2) postnatal counseling of teen mothers.

Design, Setting, And Participants: This retrospective cross-sectional study included Pregnancy Risk Assessment Monitoring System data from 2012-2016 and included mothers 19 years of age and younger.

Interventions And Main Outcome Measures: Counseling measures included tobacco, alcohol and illicit drugs, weight gain, HIV testing, influenza vaccination, breastfeeding, infant safe sleep, postpartum depression, and contraception. Bivariate associations of maternal/infant characteristics and counseling were estimated using χ tests. Multivariable logistic regression was used to assess the independent relationship between race/ethnicity and counseling.

Results: A weighted sample of 544,930 teen mothers was analyzed. Compared with non-Hispanic white (NHW) teens, non-Hispanic black teens were more likely to receive counseling on tobacco (adjusted odds ratio [aOR], 1.4; 95% confidence interval [CI], 1.10-1.77), alcohol (aOR, 1.77; 95% CI, 1.28-2.46), illicit drugs (aOR, 1.79; 95% CI, 1.33-2.41), and HIV testing (aOR, 1.62; 95% CI, 1.26-2.09). Compared with NHW teens, Hispanic teens were less likely to receive tobacco counseling (aOR, 0.78; 95% CI, 0.64-0.97) and more likely to receive influenza vaccine counseling (aOR, 1.44; 95% CI, 1.18-1.76). No difference was found in receipt of postnatal counseling.

Conclusion: Racial/ethnic differences in receipt of perinatal counseling exist, with non-Hispanic black teens being more likely to receive counseling on substance use and HIV testing and Hispanic teens being more likely to receive influenza vaccine recommendations compared with NHW teens. Ongoing investigation is needed to understand drivers of these differences.

Foreign Body Esophageal Perforation Leading to Multifocal Brain Abscesses: A Case Report.

J Emerg Med 2020 Oct 18;59(4):e131-e135. Epub 2020 Jul 18.

Department of Emergency Medicine, Denver Health and Hospital Authority, Denver, Colorado.

Background: Among those aged 5 years or younger, foreign bodies are the fourth most common pediatric exposure reported to the American Association of Poison Control Centers. Although the majority of ingested foreign bodies pass through the gastrointestinal tract without complication, those that do not spontaneously pass can lead to a number of serious complications, such as gastrointestinal obstruction or perforation, which can be complicated by bleeding from aortoesophageal fistula, secondary mediastinitis, peritonitis, esophageal or gastrointestinal fistula formation, and abscesses.

Case Report: We present the case of a 10-month-old child who presented with new-onset focal seizure in the setting of multiple brain abscesses, ultimately found to be due to esophageal perforation from a retained, metallic esophageal foreign body. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Foreign bodies that are retained for longer than 24 h after ingestion have been associated with a higher risk of complications because they are less likely to pass spontaneously through the gastrointestinal tract. Early identification and removal of foreign bodies is necessary to prevent subsequent complications. In patients who have a subacute history of cough, gagging, vomiting, and decreased oral intake with an otherwise unknown cause, foreign-body ingestion or aspiration should be considered. In addition, central nervous system abscess and infection should be considered in patients with concerns about previous foreign body ingestion or aspiration and who are newly presenting with fever, focal neurologic changes, and irritability.

Application of an LC-MS/MS method for the analysis of amlodipine, valsartan and hydrochlorothiazide in polypill for a bioequivalence study.

J Pharm Anal 2017 Oct 4;7(5):309-316. Epub 2017 Jun 4.

Department of Chemistry, School of Sciences, Gujarat University, Ahmedabad 380009, India.

A sensitive and selective method has been proposed for the simultaneous determination of amlodipine (AML), valsartan (VAL) and hydrochlorothiazide (HCTZ) in human plasma by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The analytes and their deuterated analogs were quantitatively extracted from 100 µL human plasma by solid phase extraction on Oasis HLB cartridges. The chromatographic separation of the analytes was achieved on a Chromolith RP (100 mm × 4.6 mm) analytical column within 2.5 min. The resolution factor between AML and VAL, AML and HCTZ, and VAL and HCTZ was 2.9, 1.5 and 1.4, respectively, under isocratic conditions. The method was validated over a dynamic concentration range of 0.02-20.0 ng/mL for AML, 5.00-10,000 ng/mL for VAL and 0.20-200 ng/mL for HCTZ. Ion-suppression/enhancement effects were investigated by post-column infusion technique. The mean IS-normalized matrix factors for AML, VAL and HCTZ were 0.992, 0.994 and 0.998, respectively. The intra-batch and inter-batch precision (% CV) across quality control levels was ≤ 5.56% and the recovery was in the range of 93.4%-99.6% for all the analytes. The method was successfully applied to a bioequivalence study of 5 mg AML + 160 mg VAL + 12.5 mg HCTZ tablet formulation (test and reference) in 18 healthy Indian males under fasting. The mean log-transformed ratios of , AUC and AUC and their 90% CIs were within 90.2%-102.1%. The assay reproducibility was demonstrated by reanalysis of 90 incurred samples.

Fast and sensitive LC-MS/MS method for the simultaneous determination of lisinopril and hydrochlorothiazide in human plasma.

J Pharm Anal 2017 Jun 25;7(3):163-169. Epub 2016 Nov 25.

Department of Chemistry, School of Sciences, Gujarat University, Ahmedabad 380009, India.

A sensitive and rapid liquid chromatography-tandem mass spectrometry (LC-MS/MS) method has been developed for the simultaneous determination of lisinopril (LIS) and hydrochlorothiazide (HCTZ) in human plasma using their labeled internal standards (ISs). Sample pre-treatment involved solid phase extraction on Waters Oasis HLB cartridges using 100 µL of plasma, followed by liquid chromatography on Hypersil Gold C (50 mm×3.0 mm, 5 µm) column. The analytes were eluted within 2.0 min using acetonitrile-5.0 mM ammonium formate, pH 4.5 (85:15, v/v) as the mobile phase. The analytes and ISs were analyzed in the negative ionization mode and quantified using multiple reaction monitoring. The method showed excellent linearity over the concentration range of 0.50-250.0 ng/mL for both the analytes. The intra-batch and inter-batch precision (% CV) was ≤5.26% and their extraction recoveries were in the range of 96.6%-103.1%. Matrix effect evaluated in terms of IS-normalized matrix factors ranged from 0.97 to 1.03 for both the analytes. The validated method was successfully applied to determine the plasma concentration of the drugs using 10 mg lisinopril and 12.5 mg hydrochlorothiazide fixed dose formulation in 18 healthy Indian volunteers.

An encapsulation of model drug raloxifene hydrochloride (RAL) inside the chitosan decorated pH responsive mesoporous system has a greater potential for accumulating in the tumor cells. The present study involves synthesis of surface modified mesoporous silica nanoparticles (MSN) with the aim of achieving pH sensitive drug delivery system. A silanol skeleton of MSN has been productively modified to amine intermediate which served as a firm platform to adapt chitosan grafted assembly and systematically evaluated. RAL incorporation inside the featured mesopores was performed employing novel immersion solvent evaporation methodology and evaluated further. The pH responsive behavior of formulated nano framework was studied at three different pH of a phosphate buffer saline individually. The in vitro cell viability assay on MCF-7 breast carcinoma cells was performed in time and concentration dependent manner. Finally, the hemolysis assay of designed nanoparticle was accomplished to envisage the hemocompatibility. The outcome of characterization details unveiled a perfect 2D hexagonal spherical structure gifted with higher surface area and optimum pore size for designed nanoparticles. The higher percentage grafting of amine and chitosan residue, i.e., 4.01 and 28.51% respectively along with 31.89 and 33.57% RAL loading efficiency made MSNs more attractive and applicable. Eventually, in vitro release study exhibited higher RAL release in acidic media for extended time periods confirming successful formation of pH responsive nanoparticle having controlled release property. Conclusively potential of designed nanosystem to serve efficient anti-cancer remedy was confirmed by superior behaviour of chitosan grafted MSN towards MCF-7 cells with supreme hemocompatibility.
