Transfusion effect of random donor platelet and single donor platelet in thrombocytopenic patients at tertiary care hospital of South Gujarat

Background: Platelet transfusion plays a key role in therapy for the patients with thrombocytopenia. Superiority of Single donor platelet (SDP) over Random donor platelet (RDP) transfusions is largely assumed, but unproven. Platelet Rich Plasma-Platelet concentrate (PRP-PC) and Apheresis-PC were prepared and their therapeutic efficacy were assessed in thrombocytopenic patients.Methods: This study included 60 transfusion episodes consisting of 30 SDP and 30 RDP (147units of RDP). The post transfusion efficacy of transfused platelets was assessed at 1 hour and 24 hours by corrected count increment (CCI) and percentage recovery (PR). Paired ‘t’-test was used for statistical analysis and a probability of p<0.05 was used to reject null hypothesis.Results: The mean platelet dose of SDP (n=30) and RDP (n=30) was 2.86±1.05 x 1011 and 2.36±0.54 x 1011 respectively. The mean platelet increments of SDP at 1 hour and 24 hours were 38±18.1 x 103/μl and 37.3±20.7x 103/μl. The mean platelet increments of RDP at 1 hour and 24 hours were 28.5±11.4 x 103/μl and 26 ±11.6 x 103/μl. The mean CCI of SDP at 1hour and 24 hours were 21.4 ±7.3 x 103/μl and 20.8±7.4 x 103/μl respectively. The mean CCI of RDP at 1hour and 24 hours were 18.5±6.3x 103/μl and 17.4±7.6 x 103/μl respectively.Conclusions: Post-transfusion increments were significantly higher in patients who received SDP as compared to RDP, but the CCI and PR were comparable in both groups of patients

There have been few new therapies for patients with chronic kidney disease in the last decade. However, the management of patients affected by genetic kidney disease is rapidly evolving. Inherited or genetic kidney disease affects around 10% of adults with end-stage kidney disease and up to 70% of children with early onset kidney disease. Advances in next-generation sequencing have enabled rapid and cost-effective sequencing of large amounts of DNA. Next-generation sequencing-based diagnostic tests now enable identification of a monogenic cause in around 20% of patients with early-onset chronic kidney disease. A definitive diagnosis through genomic testing may negate the need for prolonged diagnostic investigations and surveillance, facilitate reproductive planning and provide accurate counselling for at-risk relatives. Genomics has allowed the better understanding of disease pathogenesis, providing prognostic information and facilitating development of targeted treatments for patients with inherited or genetic kidney disease. Although genomic testing is becoming more readily available, there are many challenges to implementation in clinical practice. Multidisciplinary renal genetics clinics serve as a model of how some of these challenges may be overcome. Such clinics are already well established in most parts of Australia, with more to follow in future. With the rapid pace of new technology and gene discovery, collaboration between expert clinicians, laboratory and research scientists is of increasing importance to maximize benefits to patients and health-care systems

Syphilis testing adherence among women with livebirth deliveries: Indianapolis 2014-2016

Background: The number of congenital syphilis (CS) cases in the United States are increasing. Effective prevention of CS requires routine serologic testing and treatment of infected pregnant women. The Centers for Disease Control and Prevention (CDC) recommends testing all pregnant women at their first prenatal visit and subsequent testing at 28 weeks gestation and delivery for women at increased risk. Methods: We conducted a cross-sectional cohort study of syphilis testing among pregnant women with a livebirth delivery from January 2014 to December 2016 in Marion County, Indiana. We extracted and linked maternal and infant data from the vital records in a local health department to electronic health records available in a regional health information exchange. We examined syphilis testing rates and factors associated with non-testing among women with livebirth delivery. We further examined these rates and factors among women who reside in syphilis prevalent areas. Results: Among 21260 pregnancies that resulted in livebirths, syphilis testing in any trimester, including delivery, increased from 71.7% in 2014 to 86.6% in 2016. The number of maternal syphilis tests administered only at delivery decreased from 16.6% in 2014 to 4.04% in 2016. Among women living in areas with high syphilis rates, syphilis screening rates increased from 79.6% in 2014 to 94.2% in 2016. Conclusion: Improvement in prenatal syphilis screening is apparent and encouraging, yet roughly 1-in-10 women do not receive syphilis screening during pregnancy. Adherence to recommendations set out by CDC improved over time. Given increasing congenital syphilis cases, the need for timely diagnoses and prevention of transmission from mother to fetus remains a priority for public health

A green bio-organic catalyst (taurine) promoted one-pot synthesis of (R/S)-2-thioxo-3,4-dihydropyrimidine(TDHPM)-5-carboxanilides: chiral investigations using circular dichroism and validation by computational approaches

Owing to the massive importance of dihydropyrimidine (DHPMs) scaffolds in the pharmaceutical industry and other areas, we developed an effective and sustainable one-pot reaction protocol for the synthesis of (R/S)-2-thioxo-DHPM-5-carboxanilides via the Biginelli-type cyclo-condensation reaction of aryl aldehydes, thiourea and various acetoacetanilide derivatives in ethanol at 100 °C. In this protocol, taurine was used as a green and reusable bio-organic catalyst. Twenty-three novel derivatives of (R/S)-TDHPM-5-carboxanilides and their structures were confirmed by various spectroscopy techniques. The aforementioned compounds were synthesized via the formation of one asymmetric centre, one new C–C bond, and two new C–N bonds in the final product. All the newly synthesized compounds were obtained in their racemic form with up to 99% yield. In addition, the separation of the racemic mixture of all the newly synthesized compounds was carried out by chiral HPLC (Prep LC), which provided up to 99.99% purity. The absolute configuration of all the enantiomerically pure isomers was determined using a circular dichroism study and validated by a computational approach. With up to 99% yield of 4d, this one-pot synthetic approach can also be useful for large-scale industrial production. One of the separated isomers (4R)-(+)-4S developed as a single crystal, and it was found that this crystal structure was orthorhombic

Hepatitis following famotidine: a case report

H2 receptor antagonists can rarely cause idiosyncratic drug reactions leading to acute hepatitis. Famotidine, however, is considered a relatively safe drug with regards to hepatotoxicity. We report a case of a 47 year old male with a history of hepatitis C who developed acute hepatitis on the third day of hospitalization with a dramatic rise in his liver enzymes from normal values at the time of admission. The acute rise in liver enzymes made us consider an adverse drug reaction and famotidine was discontinued. Subsequently his liver enzymes came back to normal in seven days. Thus, physicians should consider famotidine induced hepatitis as a possible etiology of acute liver dysfunction

Provider Adherence to Syphilis Testing Guidelines Among Stillbirth Cases

Background The Centers for Disease Control and Prevention (CDC) recommends that all women with a stillbirth have a syphilis test after delivery. Our study seeks to evaluate adherence to CDC guidelines for syphilis screening among women with a stillbirth delivery. Methods We utilized data recorded in electronic health records for women who gave birth between January 1, 2014 and December 31, 2016. Patients were included if they were 18-44 years old and possessed an ICD-9-CM or ICD-10-CM diagnosis of stillbirth. Stillbirth diagnoses were confirmed through a random sample of medical chart reviews. To evaluate syphilis screening, we estimated the proportion of women who received syphilis testing within 300 days before stillbirth, within 30 days after a stillbirth delivery, and women who received syphilis testing both before and after stillbirth delivery. Results We identified 1,111 stillbirths among a population of 865,429 unique women with encounter data available from electronic health records. Among a sample of 127 chart reviewed cases, only 35 (27.6%) were confirmed stillbirth cases, 45 (35.4%) possible stillbirth cases, 39 (30.7%) cases of miscarriage, and 8 (6.3%) cases of live births. Among confirmed stillbirth cases, 51.4% had any syphilis testing conducted, 31.4% had testing before their stillbirth delivery, 42.9% had testing after the delivery, and only 22.9% had testing before and after delivery. Conclusions A majority of women with a stillbirth delivery do not receive syphilis screening adherent to CDC guidelines. Stillbirth ICD codes do not accurately identify cases of stillbirth

Validation of ICD-10-CM Codes for Identifying Cases of Chlamydia and Gonorrhea

Background While researchers seek to use administrative health data to examine outcomes for individuals with sexually transmitted infections, the ICD-CM-10 codes used to identify persons with chlamydia and gonorrhea have not been validated. Objectives were to determine the validity of using ICD-10-CM codes to identify individuals with chlamydia and gonorrhea. Methods We utilized data from electronic health records gathered from public and private health systems from October 1, 2015 to December 31, 2016. Patients were included if they were aged 13-44 years and received either 1) laboratory testing for chlamydia or gonorrhea or 2) an ICD-10-CM diagnosis of chlamydia, gonorrhea, or an unspecified STI. To validate ICD-10-CM codes, we calculated positive and negative predictive values, sensitivity, and specificity based on the presence of a laboratory test result. We further examined the timing of clinical diagnosis relative to laboratory testing. Results The positive predictive values for chlamydia, gonorrhea, and unspecified STI ICD-10-CM codes were 87.6%, 85.0%, and 32.0%, respectively. Negative predictive values were high (>92%). Sensitivity for chlamydia diagnostic codes was 10.6% and gonorrhea was 9.7%. Specificity was 99.9% for both chlamydia and gonorrhea. The date of diagnosis occurred on or after the date of the laboratory result for 84.8% of persons with chlamydia, 91.9% for gonorrhea, and 23.5% for unspecified STI. Conclusions Disease specific ICD-10-CM codes accurately identify persons with chlamydia and gonorrhea. However, low sensitivities suggest that most individuals could not be identified in administrative data alone without laboratory test results

A comparative study of etomidate and propofol as induction agent for intubation in patients coming to emergency medicine department

Background & Aims: An ideal induction agent for intubation in the emergency department should have hemodynamic stability, minimal respiratory side effects and rapid clearance. Etomidate and Propofol are popular rapid-acting inducing agents; our aim is to compare hemodynamic changes and adverse effects occurring between them when used as induction agents in the emergency department. Material and Methods: A study sample of 200 patients who required intubation in the emergency department were enrolled after satisfying the inclusion and exclusion criteria and were divided into two equal groups. After assessing the primary survey of airway, baseline hemodynamic parameters, Group A was given Inj. Etomidate 0.3–0.5 mg/kg iv and Group B was given Inj. Propofol 0.5–1.5 mg/kg iv as an induction agent, followed by that Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), respiratory rate (RR), oxygen saturation, myoclonus, nausea, and vomiting were monitored after induction and intubation at one, five and fifteen minutes. Result: The mean changes in HR, SBP, DBP, and MAP of groups A and B were compared, there was significant reduction in all three parameters in Propofol compared to Etomidate. In group A, out of 100 patients, 25 had myoclonus, 15 had vomiting, and no side effect was observed in the other 60 patients. In group B, out of 100 patients, 22 had apnea,14 had vomiting, and no side effect was observed in the remaining 64 patients. Conclusion: This study concludes that Etomidate is a better agent for induction than Propofol in view of hemodynamic stability. The incidence of apnea was higher with Propofol, and myoclonus more with Etomidate

Mendelian randomization study of adiposity-related traits and risk of breast, ovarian, prostate, lung and colorectal cancer

Background: Adiposity traits have been associated with risk of many cancers in observational studies, but whether these associations are causal is unclear. Mendelian randomization (MR) uses genetic predictors of risk factors as instrumental variables to eliminate reverse causation and reduce confounding bias. We performed MR analyses to assess the possible causal relationship of birthweight, childhood and adult body mass index (BMI), and waist-hip ratio (WHR) on the risks of breast, ovarian, prostate, colorectal and lung cancers. Methods: We tested the association between genetic risk scores and each trait using summary statistics from published genome-wide association studies (GWAS) and from 51 537 cancer cases and 61 600 controls in the Genetic Associations and Mechanisms in Oncology (GAME-ON) Consortium. Results: We found an inverse association between the genetic score for childhood BMI and risk of breast cancer [odds ratio (OR)=0.71 per standard deviation (s.d.) increase in childhood BMI; 95% confidence interval (CI): 0.60, 0.80; P=6.5×10-5). We also found the genetic score for adult BMI to be inversely associated with breast cancer risk (OR=0.66 per s.d. increase in BMI; 95% CI: 0.57, 0.77; P=2.5×10-7), and positively associated with ovarian cancer (OR=1.35; 95% CI: 1.05, 1.72; P=0.017), lung cancer (OR=1.27; 95% CI: 1.09, 1.49; P=2.9×10-3) and colorectal cancer (OR=1.39; 95% CI: 1.06, 1.82, P=0.016). The inverse association between genetically predicted adult BMI and breast cancer risk remained even after adjusting for directional pleiotropy via MR-Egger regression. Conclusions: Findings from this study provide additional understandings of the complex relationship between adiposity and cancer risks. Our results for breast and lung cancer are particularly interesting, given previous reports of effect heterogeneity by menopausal status and smoking status.</p
