Objectives: To study the demographics of patients: ?studying the use of PICC line in hemato-oncological patients;studying the rate of complications in PICC line;studying the cause of early removal of PICC line. Methods: All PICCs inserted in adult hemato-oncological patients in Hematology and Medical Oncology Department of Health Care Global (HCG) Hospital were studied prospectively, as per the proforma, till PICCs were removed or patient expired and the pattern of complications were noted. Results: Eighty-four PICCs were inserted over a period of initial nine months and followed for a total of 1 year with three months post insertion duration for a total of 10,868 catheter-days (mean of 129 days i.e. 4.3 months, range: 1 to 288 days). The most common indication for PICC was chemotherapy (100%). Among them 19 (22%) PICCs had complications and 12 were removed at the rate of 1.1/1000 PICC-days. Complications with haematologic malignancies were more as compared to those with solid tissue malignancies. Conclusions: Despite significant complication rates, PICCs are a relatively safe and cost effective mode of establishing central venous access.展开更多

We standardized harvesting age of bamboo shoots in central India to obtain best quality produce with respect to nutritional composition. The shoots harvested on different days （2–20 days after emergence from ground） were analyzed for their nutritional （dietary fibres, carbohydrates, proteins, total phenols, ascorbic acid, sodium, potassium, phosphorus, calcium, magnesium and phenolic acids） and anti nutritional （cyanogen） constituents. A significant variation （at p ≤ 0.5） was observed in the nutritional composition of shoots of Dendrocalamus asper, D. strictus and Bambusa tulda harvested at different days. An overall decrease was observed in proteins and total phenols while dietary fibres and carbohydrates increased with ages. Significant variation （at p ≤ 0.5） was also observed in phenolic acids while minerals did not vary significantly. Results revealed that the optimum harvesting age for D. asper, D. strictus and B. tulda was on 10–14 days, 6–10 days and 10–16 days （after emergence from the ground） respectively. These results can be used to obtain quality bamboo shoots.展开更多

In this study, 280 girls diagnosed with ICPP and 188 normal puberty control girls of similar ages were enrolled and retrospectively studied. The ICPP group had significantly lower serum 25- hydroxyvitamin D （25[OH]D） levels than the control group. Furthermore, a nonlinear relationship was found between serum 25[OH]D and ICPP, and a cut-offpoint for serum 25[OH]D was found at 31.8 ng/ml for ICPP with and without adjusting the different confounding factors. Girls with serum 25[OH]D 〉~ 31.8 ng/ml had a lower odds ratio （unadjusted： OR 0.36, 95% CI 0.15 to 0.83, P 〈 0.05; height and weight adjusted： OR 0.44, 95~0 CI 0.18 to 1.08, P = 0.072; BMI adjusted： OR 0.36, 95% CI 0.16 to 0.84, P 〈 0.05）. The ICPP subjects with 25[OH]D deficiency had a higher body mass index （BMI） than the subjects from the two other subgroups. Correlation analysis showed that vitamin D level is correlated with BMI and some metabolic parameters in the ICPP group. Our study suggested that vitamin D status may be associated with ICPP risk and may have a threshold effect on ICPP.展开更多

Methods:A total of 65 patients with CNS cryptococcal infection from August 2014 to October 2016 were retrospectively included in this study.All the patients had MRI data and clinical data.The patients were divided into two groups according to whether the patients were confirmed with identifiable underlying disease.Comparison and correlation of MRI and clinical data in both groups were investigated using independent sample t-test,Chi-square test,Mann-Whitney test and Spearman rank correlation analysis. Results:In all 65 patients,41 cases (41/65,63.1%;Group 1)had normal immunity and 24 cases (24/65,36.9%;Group 2)had at least one identifiable underlying disease.Fever,higher percentage of neutrophil (NEUT)in white blood cell (WBC),and increased cell number of cerebral spinal fluid (CSF)were much common in patients with underlying disease (Group 1 vs.Group 2:Fever:21/41 vs.21/24,x^2 =8.715,P =0.003;NEUT in WBC:73.15%vs.79.60%,Z=-2.370,P =0.018;cell number of CSF:19 vs.200,Z=-4.298,P <0.001;respectively).Compared to the patients with normal immunity,the lesions are more common in the basal ganglia among patients with identifiable underlying disease (Group 1 vs.Group 2:20/41 vs.20/24,x^2 =7.636,P =0.006).The number of the involved brain areas in patients with identifiable underlying disease were well correlated with the number of cells and pressure of CSF (r =-0.472,P =0.031,r =0.779,P =0.039;respectively). Conclusions:With the increased number of the involved brain areas in patients with identifiable underlying disease,the body has lower immunity against the organism which might result in higher intracranial pressure and more severe clinical status.展开更多
