Abstract

Background: Syphilis is a chronic sexually infectious disease caused by the Spirochaete, Treponema pallidum (T. pallidum). T. pallidum can also be transmitted by transfusion of blood or blood components from donors. It is not the transmission of syphilis that is distressing, being a sexually transmitted disease, seropositivity signifies donor's involvement in "high risk" behavior. The purpose of this study is to analyze the status of Transfusion transmitted Syphilis and other co-infections among seemingly healthy donors, targeting the non-remunerated blood donors (voluntary and replacement) during the period January, 2009- September, 2018. Material and Method: It is a cross-sectional, observational study conducted at Regional Blood Transfusion Bank Centre, C R Gardi Hospital and R D Gardi Medical College, Ujjain. All the donated blood samples were screened for Syphilis using Syphilis Rapid Test. Data was analyzed. Result: Overall prevalence of transfusion transmitted infections was 2.26%. There was increased incidence among replacement donors. Prevalence of Syphilis was estimated at 0.69%. Age is an important risk factor. Syphilis is the second most common infection after HBV among blood donors. Conclusion: There is a fluctuating trend for seropositivity of syphilis, with a slight reduction in recent years. Overall syphilis prevalence is high in the study region. With the adaptation of strict donor selection criteria, use of sensitive screening tests and implementation of strict guidelines for blood transfusion it may be possible to reduce the prevalence of TTI.

Abstract

Background: The kidney-brain interaction has been a topic of growing interest. Past studies of the effect of kidney function on intracerebral hemorrhage (ICH) outcomes have yielded inconsistent findings. Although the second, main phase of the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT2) suggests the effectiveness of early intensive blood pressure (BP) lowering in improving functional recovery after ICH, the balance of potential benefits and harms of this treatment in those with decreased kidney function remains uncertain. Study Design: Secondary analysis of INTERACT2, which randomly assigned patients with ICH with elevated systolic BP (SBP) to intensive (target SBP < 140 mm Hg) or contemporaneous guideline-based (target SBP < 180 mm Hg) BP management. Setting & Participants: 2,823 patients from 144 clinical hospitals in 21 countries. Predictors Admission estimated glomerular filtration rates (eGFRs) of patients were categorized into 3 groups based on the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) creatinine equation: normal or high, mildly decreased, and moderately to severely decreased (>90, 60-90, and <60 mL/min/1.73 m2, respectively). Outcome(s): The effect of admission eGFR on the primary outcome of death or major disability at 90 days (defined as modified Rankin Scale scores of 3-6) was analyzed using a multivariable logistic regression model. Potential effect modification of intensive BP lowering treatment by admission eGFR was assessed by interaction terms. Result(s): Of 2,623 included participants, 912 (35%) and 280 (11%) had mildly and moderately/severely decreased eGFRs, respectively. Patients with moderately/severely decreased eGFRs had the greatest risk for death or major disability at 90 days (adjusted OR, 1.82; 95% CI, 1.28-2.61). Effects of early intensive BP lowering were consistent across different eGFRs (P = 0.5 for homogeneity). Limitation(s): Generalizability issues arising from a clinical tri

Abstract

Infants’ ability to discriminate between auditory stimuli presented in rapid succession and differing in fundamental frequency (Rapid Auditory Processing [RAP] abilities) has been shown to be anomalous in infants at familial risk for Language Learning Impairment (LLI) and to predict later language outcomes. This study represents the first attempt to investigate RAP in Italian infants at risk for LLI (FH+), examining two critical acoustic features: frequency and duration, both embedded in a rapidly-presented acoustic environment. RAP skills of 24 FH+ and 32 control (FH−) Italian 6-month-old infants were characterized via EEG/ERP using a multi-feature oddball paradigm. Outcome measures of expressive vocabulary were collected at 20 months. Group differences favoring FH− infants were identified: in FH+ infants, the latency of the N2* peak was delayed and the mean amplitude of the positive mismatch response was reduced, primarily for frequency discrimination and within the right hemisphere. Moreover, both EEG measures were correlated with language scores at 20 months. Results indicate that RAP abilities are atypical in Italian infants with a first-degree relative affected by LLI and that this impacts later linguistic skills. These findings provide a compelling cross-linguistic comparison with previous research on American infants, supporting the biological unity hypothesis of LLI.

Abstract

This paper reports detailed molecular dynamics simulations over a large pressure4emperature range (0-140 GPa and 300-2000 K) in the Earth's mantle starting from the upper mantle phase enstatite MgSi[O.sub.3]. The simulated seismic velocities show several discontinuities corresponding to the phase transitions of enstatite. With increasing pressure, enstatite MgSi[O.sub.3] transforms first to a new novel five-coordinated silicon phase, and then to the lower-mantle perovskite phase involving six-coordinated silicon atoms. The new intermediate phase is crystalline but orientafionally disordered. The calculated seismic velocities and densities across the phase transitions for a pure MgSi[O.sub.3] mantle are consistent with previous estimates. These studies suggest that the major discontinuities between the upper mantle, transition zone, and the lower mantle could arise partially due to the changes in the silicon coordination.

Abstract

A B S T R A C T Cervical metastasis is often the only presenting feature in patients with squamous cell carcinoma of the head and neck (HNSCC). These metastases frequently undergo cystic degeneration, and may be difficult to distinguish from other benign cystic squamous lesions of the head and neck. Fine needle aspiration for cytopathology (FNAC) is frequently performed, but the results obtained may not be conclusive. P16 immunohistochemistry may be carried out. However, the value of this test in differentiating between benign and malignant cystic lesions of the head and neck remains unclear.

Abstract

We previously found no difference in healthy young adults' plasma cholesterols between palmolein and olive oil as the major dietary lipid, although the former is high in palmitic acid (16:0) but the latter in oleic acid (18:1 cis). In the experiment reported here we compared the effects of palmolein against another monounsaturated oil, highly oleic sunflower oil (HOSO), on plasma cholesterol in both young and middle-aged healthy adults. The test oils were provided as frying oil of potato crisps (150 g/day in men; 100 g/day in women) against low-fat background diets in free-living motivated volunteers. The design was a randomised double-blind 4-week/3-week crossover trial. Compliance was monitored with continuous dietary diaries and by measuring (fasting) plasma lipid fatty-acid pattern. Plasma lipids and vitamin-E compounds were measured at the start and twice at the end of each test period. In combined young plus older subjects (n = 42) mean plasma total and low-density-lipoprotein cholesterol (LDL-c) values were both 7% (significantly) lower on HOSO than on palmolein, but because high-density-lipoprotein cholesterol (HDL-c) was also 5% lower, the LDL-c/HDL-c ratio was only 3% lower on HOSO than on palmolein. The difference between the present results with HOSO and previous results with olive oil both compared against palmolein suggest that olive oil is associated with higher plasma cholesterols than other monounsaturated oils. In both the young and older subgroup, LDL-c was lower on HOSO but because HDL-c moved down too in the young subgroup, the LDL-c/HDL-c ratio was lower on HOSO only in the older subjects. Palmolein has an unusual pattern of E vitamins, with a high content of tocotrienols, notably the gamma-isomer. Unlike alpha-tocopherol however, there was no sign of these tocotrienols in subjects' plasmas.

Abstract

Background: Human parvovirus B19 (B19) virus is a newly recognized agent for transfusion transmitted diseases. Beta-thalassemia major patients receive a hypertransfusion regimen, hence, are prone to acquire B19 infection; moreover, B19 escapes viral inactivation methods and donor units are not tested for B19, but there are just a couple of studies globally and none from the Asian continent. Hence, a study was designed to find the frequency of B19 infection and its transmission in multitransfused thalassemia patients. Materials and Methods: Ninety multitransfused beta-thalassemia major (thalassemia) patients, 32 controls (age, sex matched) without any history of transfusion were enrolled. Besides the donor units were tested in B19 un-infected patients. B19 specific IgG and IgM antibodies in the sera were analyzed by ELISA (in-house), using B19 VPI and VP2 recombinant and purified antigens; additionally HBsAg and anti-HIV and anti-HCV antibodies were tested for coexisting infections. Results: Seventy-three (81%) thalassemia patients tested positive for anti-B19 IgG antibodies as compared to seven (21%) in the controls group (P < 0.01), while anti-B19 IgM antibodies were detected in 37 (41.1%) compared to two (6.2%) in the controls (P < 0.01). Mean age of the thalassemia patient was eight years (range 2 - 18 years) and B19 infection was highest in the six-to-ten year range. Seropositivity increased with the number of transfusions. Two of the four HBsAg positive and five of the seven anti-HCV IgM antibody-positive patients also had anti-B19 IgM. After a six-month follow-up, four (25%) of the 16 seronegative patients seroconverted and anti-B19 IgM antibodies were detected in their donor units. Conclusions: Most of multitransfused thalassemics were B19 seropositive or had anti-B19 IgM; in the remaining uninfected group, B19 got transmitted through infected / IgM-positive donor units.

Abstract

An infant's ability to process auditory signals presented in rapid succession (i.e. rapid auditory processing abilities [RAP]) has been shown to predict differences in language outcomes in toddlers and preschool children. Early deficits in RAP abilities may serve as a behavioral marker for language‐based learning disabilities. The purpose of this study is to determine if performance on infant information processing measures designed to tap RAP and global processing skills differ as a function of family history of specific language impairment (SLI) and/or the particular demand characteristics of the paradigm used. Seventeen 6‐ to 9‐month‐old infants from families with a history of specific language impairment (FH+) and 29 control infants (FH−) participated in this study. Infants’ performance on two different RAP paradigms (head‐turn procedure [HT] and auditory‐visual habituation/recognition memory [AVH/RM]) and on a global processing task (visual habituation/recognition memory [VH/RM]) was assessed at 6 and 9 months. Toddler language and cognitive skills were evaluated at 12 and 16 months. A number of significant group differences were seen: FH+ infants showed significantly poorer discrimination of fast rate stimuli on both RAP tasks, took longer to habituate on both habituation/recognition memory measures, and had lower novelty preference scores on the visual habituation/recognition memory task. Infants’ performance on the two RAP measures provided independent but converging contributions to outcome. Thus, different mechanisms appear to underlie performance on operantly conditioned tasks as compared to habituation/recognition memory paradigms. Further, infant RAP processing abilities predicted to 12‐ and 16‐month language scores above and beyond family history of SLI. The results of this study provide additional support for the validity of infant RAP abilities as a behavioral marker for later language outcome. Finally, this is the first study to use a battery of infant tasks to demonstrate multi‐modal processing deficits in infants at risk for SLI. peerReviewed

Abstract

&mechanism was tried to develop and enrich soil organic matter and to sustain productivity of the ricerice cropping systems through its in-built biomass production from Sesbania rostrata as a relay crop. In order to develop such mechanism a number of field experiments were conducted with the participation of farmers during 1993 to 1996. Findings revealed that relay cropping of S. rostrata did not affect significantly the yields of aus and boro rice indicating its sustainability to fit it into the system. The relay cropping of S. rostrata could add up to 35.97 t ha-1 of green biomass to the soil depending upon treatments.'Incorporation of 15 to 17.5 t ha-1 of S. rostrata green biomass was as pood as application of 80 kg N ha -1 for rice yield. Post harvest soil analysis data indicated that 25 t ha- green biomass of S. rostrata was necessary to maintain the current status of soil organic matter.

Abstract

Transfusion transmitted disease (TTD) is a major challenge to the transfusion services all over the world. The problem of TTD is directly proportionate to the prevalence of the infection in the blood donor community. In India, hepatitis B/C, HIV, malaria, syphilis, cytomegalo virus, parvo-virus B-19 and bacterial infections are important causes of concern. Hepatitis B and C infections are prevalent in India and carrier rate is about 1–5% and 1%, respectively. Post transfusion hepatitis B/C is a major problem in India (about 10%) because of low viraemia and mutant strain undetectable by routine ELISA. HIV prevalence among blood donors is different in various parts of the country. It may not be so alarming as projected by some agencies. In one study from north India, confirmed HIV positivity was found in 0.2/1000 blood donor. Post transfusion CMV is difficult to prevent but use of leukocyte filters may help to reduce it significantly. Parvo virus B-19 infection in blood donors is 39.9% which may increase morbidity in multitransfused or immunocompromised patients. Current symphilis tests may not be sensitive but it should be continued to exclude high-risk donors. Malaria is a real problem for India due to the lack of a simple and sensitive screening test. Incidence of bacterial contamination is greatly reduced due to improved collection/ preservation techniques and use of antibiotics in patients. However, proper vigilance and quality control is needed to prevent this problem. Total dependence of altruistic repeat voluntary donors and use of sensitive laboratory tests may help Indian blood transfusion services to reduce incidences of TTDs.

Abstract

A total of 39 patients with thalassaemia major who received multiple blood transfusions were followed up clinically and serologically for 3 successive years (1993, 1994, 1995). They were screened for hepatitis B surface antigen (HBsAg), and antibodies to hepatitis B core (HBc-total), hepatitis C virus (HCV), human immunodeficiency virus I and II (HIV-I/II) and cytomegalovirus (CMV-total). In spite of transfusing HBsAg screened (by third generation ELISA) blood from voluntary non-remunerated donors, there was a significant increase of HBsAg positivity (P0.001) from 17.9 per cent (1993) to 35.9 per cent (1994) to 69.2 per cent (1995). This was probably due to the prevalence of undetectable HBV infection in the population. Anti HBc was present in 17 (43.6%), 14 (35.9%) and 16 (41%) patients in consecutive years. An increase in the units of blood transfused was observed every year. Blood units were not screened for anti HCV antibodies but a gradual increase in positivity [9 (23%), 12 (30.7%) and 14 (35.9%) patients] was seen in consecutive years. Anti-HIV antibodies were found in a 16 yr old male who was included in the study without any clinical evidence of AIDS. Anti CMV antibody was found in 30 (76.9%), 32 (82%) and 29 (74.3%) patients without any apparent clinical infection. Some patients showed change of antibody pattern (from negative to positive or vice versa) and a few patients showed inconsistent results probably due to immune modulation. Recruitment of 'repeat' non-remunerated voluntary blood donors may reduce the risk of high HBV transmission.
