Q: Context: A prospective radiographic analysis of deformity correction during the balloon kyphoplasty procedure.', 'To determine the spontaneous reduction of the deformity in prone position, the subsequent deformity correction by the inflatable bone tamp, and the overall deformity correction after deposition of the cement.', 'Fracture mobility has been shown to contribute to fracture reduction in vertebroplasty. Spontaneous reduction has not been taken into account in recently published series of balloon kyphoplasty, but it must be considered when performing vertebral augmentation and when reporting and interpreting the significance of vertebral height restoration.', 'A consecutive series of 39 osteoporotic vertebral compression fractures were treated in 30 patients. Lateral radiographs were taken and analyzed at six different time points: 1) Preoperative standing. During the kyphoplasty procedure, four consecutive radiographs were obtained: 2) after placing the patient in prone position on the operation table, 3) after inflation of the bone tamp (IBT), 4) after deflation and removal of the IBT, and 5) after deposition of the cement. 6) Standing lateral radiographs were taken after the procedure. All fractures were analyzed for improvement in sagittal alignment (Cobb angle, kyphotic angle, sagittal index, vertebral height), complications, and reduction of pain (VAS).', 'Placement of the patient in prone position displayed a significant spontaneous reduction in deformity of 6.5 degrees +/- 4.1 degrees Cobb angle. Inflation of the IBT demonstrated a further reduction of the fracture and a significant improvement of the Cobb angle of 3.4 degrees compared with baseline prone. After deflation and removal of the IBT and placement of the cement, no significant loss of fracture reduction was seen. Postoperative measurement of the Cobb angle by means of standing radiographs demonstrated a 3.1 degrees significant loss of reduction compared with the intraoperative measurement in prone position after cement application. Cement leaks occurred in 9 of 39 vertebral fractures. All patients subjectively reported immediate relief of their typical fracture pain. The VAS score significantly improved from 8.7 +/- 1.4 before surgery to 2.3 +/- 0.9.
Answer: The restoration of height in kyphoplasty is attributed to dynamic fracture mobility as well as to the expansion of the inserted balloon tamp.

A: Is balloon kyphoplasty effective in deformity correction of osteoporotic vertebral compression fractures?

Q: Context: Ficus religiosa L. is one of the most relevant members of the family of Moraceae. It is the most sacred tree of South Asia, and it is used in traditional Ayurvedic and Unani medicine to cure respiratory disorders like cough, wheezing and asthma. Some studies were performed to investigate the anti-asthmatic potential of F. religiosa bark, leaves and fruit extracts but none of them tested their antiviral activity against viruses responsible for the exacerbation of wheezing and asthma.', 'The present study was undertaken to investigate the antiviral activity of F. religiosa L. extracts against respiratory viruses such as human respiratory syncytial virus (RSV) and human rhinovirus (HRV).', 'The antiviral activity of F. religiosa L. was tested in vitro by plaque reduction and virus yield assays and the major mechanism of action was investigated by virus inactivation and time-of-addition assays.', 'F. religiosa L. methanol bark extract was the most active against HRV with an EC50 of 5.52 µg/mL. This extract likely inhibited late steps of replicative cycle. Water bark extract was the most active against RSV with an EC50 between 2.23 and 4.37 µg/mL. Partial virus inactivation and interference with virus attachment were both found to contribute to the anti-RSV activity. Replication of both viruses was inhibited in viral yield reduction assays.
Answer: The results of the present study demonstrate that F. religiosa L. is endowed with antiviral activity against RSV and HRV in vitro. Further work remains to be done to identify the active components and to assess the therapeutic potential in vivo.

A: Do ficus religiosa L. bark extracts inhibit human rhinovirus and respiratory syncytial virus infection in vitro?

Q: Context: There are safety concerns about TASER conducted electrical weapon (CEW) use on humans, and there have been media reports of adverse human outcomes after CEW exposure. Conducted electrical weapons are often used on physically exhausted subjects. A single CEW application of a CEW is generally accepted to be 5 seconds of exposure. Some exposures in reality involve more than 5 seconds. We sought to determine if a prolonged (15 seconds) CEW exposure on exhausted humans caused acidosis, hyperkalemia, serum lactate change, or troponin change.', 'This was a prospective study of generally healthy human volunteers. Medical histories and baseline serum values were obtained, and several of the volunteers did have acute or chronic medical problems. Subjects underwent an exercise protocol until subjective exhaustion. Exhaustion was defined by the volunteer no longer being able to perform the exercise at a given pace. Blood was drawn immediately (defined as within 20 seconds) after exercise and was immediately followed by a 15-second CEW exposure. Blood was drawn immediately after exposure and again at 16 to 24 hours after exposure. Blood was analyzed for pH, pco(2), potassium, lactate, and troponin. Data were compared using Wilcoxon signed rank tests.', 'There were 38 subjects enrolled with an average age of 39 years. The following health conditions were reported among the volunteers: hypertension (2), gastritis/reflux (2), active respiratory tract infections (3), asthma (2), chronic muscular pain conditions (4), pituitary adenoma (1) and glaucoma (1). Sixteen volunteers reported use of prescription medication at the time of their participation. The median initial pH of 7.38 (interquartile range [IQR], 7.35-7.40) decreased to 7.23 (IQR, 7.19-7.31) immediately after exercise. Immediately after exposure, median pH was 7.22 (IQR, 7.18-7.25). It was 7.39 (IQR, 7.37-7.43) at 24 hours. The pCO2 increased from 46.3 (IQR, 43.0-54.5) to 57.4 (IQR, 49.9-67.7) immediately after exercise, decreased to 51.3 (IQR, 44.4-65.0) immediately after exposure, and was 46.3 (IQR, 42.7-51.7) at 24 hours. Lactate increased from a median of 1.65 (IQR, 1.14-2.55) to 8.39 (IQR, 6.98-11.66) immediately after exercise, increased to 9.85 (IQR, 7.70-12.87) immediately after exposure, and was 1.02 (IQR, 0.91-1.57) at 24 hours. Serum potassium increased from 3.9 (IQR, 3.8-4.4) to 4.2 (IQR, 4.0-4.9) immediately after exercise, decreased to 3.8 (IQR, 3.7-4.4) immediately after exposure, and was 4.1 (IQR, 3.9-4.6) at 24 hours. No troponin elevations were detected.
Answer: Prolonged CEW application on exhausted humans was not associated with worsening change in pH or troponin. Decreases in pCO2 and potassium and a small increase in lactate were found. Worsening acidosis theories due to CEW use in this population are not supported by these data.

A:
Does prolonged TASER use on exhausted humans worsen markers of acidosis?
