Is the h-index predictive of greater NIH funding success among academic radiologists?

Among 210 professors of radiology, 48 (23%) secured at least one NIH grant. The mean h-index was significantly higher among individuals who secured at least one NIH grant (19.1) compared to those who did not (10.4) (P<.0001). Professors with h-indices<10 compared to those with h-indices>10 were significantly less likely to receive NIH funding (odds ratio, 0.07; P = .0321). However, h-indices>10 were not significantly predictive of greater funding. No significant relationships were observed between h-index and the number of grant awards, years of prior funding, the amounts of grant awards, or grant classification.

Is minimally invasive mitral valve repair with artificial chords reproducible and applicable in routine surgery?

Analyzable responses were obtained from 1662 clinicians and 82 CPs. Both clinicians and CPs considered some terms, e.g., agglutination, useful, whereas only CPs considered other terms, e.g., ghost cells, useful. All groups interpreted certain terms, e.g., Heinz bodies, correctly, whereas some clinicians misinterpreted others, e.g., eccentrocytes. Responses revealed that CPs often do not report RBC-M they consider insignificant, when present in low numbers. Twenty-eight percent of clinicians think CPs review all blood smears while only 19% of CPs report reviewing all smears.

Intravenous administration of metoclopramide by 2 min bolus vs 15 min infusion: does it affect the improvement of headache while reducing the side effects?

Rates of active travel vary by socio-economic position, with higher rates generally observed among less affluent populations. Aspects of both social and built environments have been shown to affect active travel, but little research has explored the influence of physical environmental characteristics, and less has examined whether physical environment affects socio-economic inequality in active travel. This study explored income-related differences in active travel in relation to multiple physical environmental characteristics including air pollution, climate and levels of green space, in urban areas across England. We hypothesised that any gradient in the relationship between income and active travel would be least pronounced in the least physically environmentally-deprived areas where higher income populations may be more likely to choose active transport as a means of travel.

Comparison between results obtained in the practices and those in the reference hospital laboratory (gold standard), which used the same method of testing for INR, showed a correlation coefficient of 0.96. Correlation coefficients comparing the results with the various standard laboratory techniques ranged from 0.86 to 0.92. It was estimated that up to 53% of tests would have resulted in clinically significant differences (change in warfarin dose) depending upon the site and method of testing. The practice derived results showed a positive bias ranging from 0.28 to 1.55, depending upon the site and method of testing.

Is peak concentration needed in therapeutic drug monitoring of vancomycin?

Significant differences in trough concentration (Cmin)/minimum inhibitory concentration (MIC) and area under the serum concentration-time curve (AUC0-24)/MIC were observed between the response and non-response groups. Significant differences in Cmin and AUC0-24 were observed between the nephrotoxicity and non-nephrotoxicity groups. Receiver operating characteristic curves revealed high predictive values of Cmin/MIC and AUC0-24/MIC for efficacy and of Cmin and AUC0-24 for safety of vancomycin.

Is peak concentration needed in therapeutic drug monitoring of vancomycin?

Improvement of motor function occurred in 21% after S + RT and 24% after RT (p = 0.39). The 1-year local control rates were 81% and 91% (p = 0.44), while the 1-year survival rates were 46% and 39% (p = 0.71). In the matched-pair analysis of patients receiving DDSS, improvement of motor function occurred in 22% after DDSS + RT and 24% after RT alone (p = 0.92). The 1-year local control rates were 95% and 89% (p = 0.62), and the 1-year survival rates were 54% and 43% (p = 0.30). In the matched-pair analysis of patients receiving LE, improvement of motor function occurred in 20% after LE + RT and 23% after RT alone (p = 0.06). The 1-year local control rates were 50% and 92% (p = 0.33). The 1-year survival rates were 32% and 32% (p = 0.55).

Can autologous platelet-rich plasma gel enhance healing after surgical extraction of mandibular third molars?

A prospective randomized comparative clinical study was undertaken over a 2-year period. Patients requiring surgical extraction of a single impacted third molar and who fell within the inclusion criteria and indicated willingness to return for recall visits were recruited. The predictor variable was application of PRP gel to the socket of the third molar in the test group, whereas the control group had no PRP. The outcome variables were pain, swelling, and maximum mouth opening, which were measured using a 10-point visual analog scale, tape, and millimeter caliper, respectively. Socket healing was assessed radiographically by allocating scores for lamina dura, overall density, and trabecular pattern. Quantitative data were presented as mean. Mann-Whitney test was used to compare means between groups for continuous variables, whereas Fischer exact test was used for categorical variables. Statistical significance was inferred at P<.05.

Can autologous platelet-rich plasma gel enhance healing after surgical extraction of mandibular third molars?

Experiments were carried on the leaves of two double-haploid lines of winter oil-seed rape (Brassica napus subsp. oleifera), differing in winter survival and resistance to blackleg fungus (Leptosphaeria maculans).
