Ziconotide (ZCN), a nonopioid analgesic, is first-line intrathecal therapy for patients with severe chronic pain refractory to other management options. We describe three cases of ZCN-induced movement disorders.

Case one is a 64-year-old woman who presented with oro-lingual (OL) dyskinesia with dysesthesias and bilateral upper extremity kinetic tremor. Case two is a 43-year-old man with a 20-month history of ZCN treatment who developed OL dyskinesia with dysesthesias, involuntary left hand and neck movements, hallucinations, dysesthesias on his feet, and gait imbalance. Case three is a 70-year-old man with a 4-month history of ZCN use who developed OL dyskinesia with dysesthesias.

Intrathecal treatment of pain with ZCN may be complicated by a drug-induced movement disorder where OL dyskinesia is characteristic. The movement disorder is likely to be dose related and reversible with ZCN discontinuation, but a chronic movement disorder is also possible.

The Tremor Research Group Essential Tremor Rating Scale (TETRAS) is a well-validated instrument to assess essential tremor. However, similar to all other tremor rating scales, specific instructions for individual tasks are based mostly on expert opinion and tradition. Several tasks have multiple possible variations that have never been compared to determine if they impact score.

Using blinded, randomized videotapes, a group of tremor experts evaluated multiple ET patients to determine 1. whether assessments of spirals and writing samples are similar if the rater only sees the end result as opposed to actually watching the task, 2. whether arm tremor ratings (postural and wing-beating) are similar if the subjects hold both hands out concurrently vs. if they only hold one arm out at a time, 3. whether heal to shin tremor scores vary between supine and sitting, and 4. compared cursive vs script writing samples.

Intraclass correlation coefficients (ICC) were excellent (>0.95) for all arm assessments. Writing tremor was rated worse if only rating the spiral/writing photos (p < 0.05) rather than also viewing the writing process, arm tremor scores were higher if each arm was rated individually (p < 0.001), heal to shin scores were higher when done sitting (p = 0.01), and cursive writing tended to be rated higher than script (p = 0.08).

Minor procedure differences when administering the TETRAS can significantly alter results.

The authors surveyed internal medicine interns at a large academic medical center regarding clinical and non-clinical topics that would be useful for an internal medicine residency preparatory curriculum. The response rate was 79% (64/81). A rational approach to antibiotics (42%) and electrolyte management (41%) were the most frequent clinical topics and cross-cover (69%) was the most frequent non-clinical topic selected by interns.Light-driven biocatalysis in recombinant cyanobacteria provides highly atom-efficient cofactor regeneration via photosynthesis, thereby remediating constraints associated with sacrificial cosubstrates. However, despite the remarkable specific activities of photobiocatalysts, self-shading at moderate-high cell densities limits efficient space-time-yields of heterologous enzymatic reactions. Moreover, efficient integration of an artificial electron sink into the tightly regulated network of cyanobacterial electron pathways can be highly challenging. Here, we used C=C bond reduction of 2-methylmaleimide by the NADPH-dependent ene-reductase YqjM as a model reaction for light-dependent biotransformations. Time-resolved NADPH fluorescence spectroscopy allowed direct monitoring of in-cell YqjM activity and revealed differences in NADPH steady-state levels and oxidation kinetics between different genetic constructs. This effect correlates with specific activities of whole-cells, which demonstrated conversions of >99%. Further channelling of electrons toward heterologous YqjM by inactivation of the flavodiiron proteins (Flv1/Flv3) led to a 2-fold improvement in specific activity at moderate cell densities, thereby elucidating the possibility of accelerating light-driven biotransformations by the removal of natural competing electron sinks. In the best case, an initial product formation rate of 18.3 mmol h-1 L-1 was reached, allowing the complete conversion of a 60 mM substrate solution within 4 h.We present an artificial metalloenzyme based on the transcriptional regulator LmrR that exhibits dynamics involving the positioning of its abiological metal cofactor. The position of the cofactor, in turn, was found to be related to the preferred catalytic reactivity, which is either the enantioselective Friedel-Crafts alkylation of indoles with β-substituted enones or the tandem Friedel-Crafts alkylation/enantioselective protonation of indoles with α-substituted enones. The artificial metalloenzyme could be specialized for one of these catalytic reactions introducing a single mutation in the protein. The relation between cofactor dynamics and activity and selectivity in catalysis has not been described for natural enzymes and, to date, appears to be particular for artificial metalloenzymes.
The purpose of this study was to investigate the clinical effects of oral carbohydrate intake for cephalomedullary nailing on proximal femoral fractures and patient satisfaction.

88 patients were admitted to our hospital with proximal femoral fracture from July 2019 to December 2019. All patients were treated with closed reduction and internal fixation (CR&IF, Cephalomedullary nailing) under spinal anesthesia. The exclusion criteria included the presence of endocrine disorders including diabetes mellitus (DM), patients treated with steroids, and cognitive impairment. Additionally, those with fasting blood glucose levels above 126 mg / dl or HbA1C> 6.5% were considered as having undiagnosed DM. After obtaining informed consent, the subjects were randomized into either the preoperative oral carbohydrate (POC) group or control group. Patients who were assembled into the control group fasted including water from midnight of the day of the surgical procedure according to the conventional method. Liraglutide research buy Patients assembled into the POC group received 400 ml of oral carbohydrate solution (Nucare NONPO, DAESANG, 12.
