RESUMO

BACKGROUND: Diabetes is the eighth leading cause of death and has a substantial impact on the United States (U.S.) health care system. Recent changes to major insurance formularies allow for increased access to continuous glucose monitors (CGM). Community pharmacists routinely assist and educate patients about diabetes care, including usage of CGM. OBJECTIVES: The purpose of this study was to evaluate the clinical impact of a community pharmacist remote CGM monitoring service on patients' glycemic metrics. Patient completion of comprehensive diabetes standards of care and pharmacist interventions and recommendations were assessed as secondary objectives. METHODS: This study was a prospective, feasibility study conducted at two pharmacies within one regional division of a large community pharmacy chain between November 2022 and June 2023. A pharmacist conducted patient enrollment visits and remotely monitored CGM glycemic metrics via cloud-based platforms per the study protocol. CGM glycemic metrics were evaluated for each patient three months pre- and post-study enrollment, including time above range (TAR), time in range (TIR), time below range (TBR), glucose management indicator (GMI), average glucose, CGM utilization rate, and glucose variability. Metrics were evaluated for statistical significance using the Wilcoxon signed-rank test and descriptive statistics. RESULTS: Pharmacists enrolled 36 patients in this study with 20 patients completing the full three-month study period per protocol. There was a statistically significant improvement in three of eight glycemic metrics (very high TAR, TIR, and average glucose). Specifically, TIR had the largest improvement from 61.8% pre-enrollment to 69.9% (p < 0.006) post-enrollment. All other pertinent glycemic metrics displayed improvements but were not statistically significant. CONCLUSION: The results demonstrate clinically and statistically significant improvements in several glycemic metrics for patients who participated in the community pharmacist-led remote CGM monitoring service, which may result in improved diabetes control and fewer long-term diabetes-related health complications.

RESUMO

The purpose of this study was to assess potential gender differences in size of the lateral and medial trochlea of the male and female knee as well as the variation within gender of potential osteochondral autograft transfer (OAT) donor site area. Two hundred and twelve skeletally mature patients, 106 males and 106 females, who underwent a 3T magnetic resonance imaging of the knee for a variety of indications were utilized for analysis. Exclusion criteria included degenerative arthritis, trochlear dysplasia, and poor image quality. Medial and lateral femoral trochlear cartilage width was obtained using a linear radiologic measurement tool. Widths were measured from a reproducible anatomic location representing the maximal trochlear dimension in a region where donor plugs are commonly harvested. Trochlear width was also plotted as a function of patient height. Statistical analysis was performed using a two-sample t-test. The mean and standard deviation of the lateral trochlear cartilage width (mm) for males and females were 23.38 +/- 2.14 and 20.44 +/- 2.16, respectively (p < 0.00001). The mean and standard deviation of the medial trochlear cartilage width (mm) for males and females were 14.16 +/- 2.17 and 11.78 +/- 2.03, respectively (p < 0.00001). The overall range in trochlear width for both the lateral and medial sides was 22.22 and 19.73 mm for males and females, respectively. A graft measuring 10 mm could represent as little as 34% of the lateral trochlea in males versus as much as 65% in females. Our results indicate that donor OAT plug diameter relative to available trochlear cartilage width will vary significantly both between genders and individual patients. Trochlear width variability and its potential implications on donor site morbidity may be an important consideration when contemplating osteochondral plug harvest for OAT or other indications. The level of evidence is IV.

RESUMO

Surgical repair of articular cartilage defects in the knee currently utilizes surgical algorithms based on absolute defect size. These algorithms, which have not been validated, are currently utilized not only by surgeons but also by insurance carriers for justification of reimbursement policy. However, current algorithms do not account for morphological differences between individual patients and defect size relative to condylar dimension. We hypothesized that a significant difference in relative defect size compared with condylar dimension may exist between individuals. A 3T magnetic resonance imaging from 220 skeletally mature patients, 110 males and 110 females, were analyzed. Exclusion criteria included degenerative arthritis, anatomical defects, poor image quality, and genetic abnormalities such as dwarfism. Utilizing a radiological curved measurement probe, the femoral condylar articular width was obtained for both the medial and lateral condyles. The mean condylar width from a reproducible anatomic location representing the maximal condylar dimension was measured. Statistical analysis was performed using a two-sample t-test. The lateral condyle articular cartilage width (mm) for males and females was 31.62 ± 3.54 and 26.53 ± 3.70, respectively (p < 0.0001). The medical condyle articular cartilage width was 27.26 ± 4.42 and 23.05 ± 4.11 (p < 0.00001). There was a width variation up to 22.66 mm between male patients and 22.10 mm between female patients. Differences up to 28.26 mm were found between males and females. A condylar defect measuring 10 mm represents as little as 24.29% of a condyle in some males versus as much as 77.46% in smaller females. Existing surgical algorithms for condylar chondral defects apply absolute size to patients regardless of individual condylar variations. Our study suggests the relative sizes of the defect vary significantly from male to female patients as well as within the same gender. Future studies may investigate clinical outcomes utilizing surgical algorithms that take into account these differences.

RESUMO

In just over a decade, the field of biomedical research has witnessed a radical evolution in technologies for the 3- and 4-dimensional imaging of biological samples. Light sheet fluorescence microscopy is quickly developing into a powerful approach for fast, volumetric imaging of cells, tissues and living organisms. This review touches on the development of 3-dimensional imaging, from its foundations, namely from the invention of confocal microscopy in the twentieth century to more recent examples, notably the IsoView SPIM, the Lattice Light Sheet Microscope and swept confocally aligned planar excitation. These technologies overcome the limitations of conventional optical sectioning techniques and enable unprecedented levels of spatio-temporal resolution with low levels of phototoxicity. Developing in parallel with powerful computational approaches, light sheet based methods promise to completely transform cell biology as we know it today.

RESUMO

BACKGROUND: Data obtained during arrhythmia is retained in real-time cardiovascular magnetic resonance (rt-CMR), but there is limited and inconsistent evidence to show that rt-CMR can accurately assess beat-to-beat variation in left ventricular (LV) function or during an arrhythmia. METHODS: Multi-slice, short axis cine and real-time golden-angle radial CMR data was collected in 22 clinical patients (18 in sinus rhythm and 4 patients with arrhythmia). A user-initialized active contour segmentation (ACS) software was validated via comparison to manual segmentation on clinically accepted software. For each image in the 2D acquisitions, slice volume was calculated and global LV volumes were estimated via summation across the LV using multiple slices. Real-time imaging data was reconstructed using different image exposure times and frame rates to evaluate the effect of temporal resolution on measured function in each slice via ACS. Finally, global volumetric function of ectopic and non-ectopic beats was measured using ACS in patients with arrhythmias. RESULTS: ACS provides global LV volume measurements that are not significantly different from manual quantification of retrospectively gated cine images in sinus rhythm patients. With an exposure time of 95.2 ms and a frame rate of > 89 frames per second, golden-angle real-time imaging accurately captures hemodynamic function over a range of patient heart rates. In four patients with frequent ectopic contractions, initial quantification of the impact of ectopic beats on hemodynamic function was demonstrated. CONCLUSION: User-initialized active contours and golden-angle real-time radial CMR can be used to determine time-varying LV function in patients. These methods will be very useful for the assessment of LV function in patients with frequent arrhythmias.

RESUMO

OBJECTIVE: Due to risk of serious adverse drug events (ADEs) sotalol use is limited in renal insufficiency and heart failure. To reduce potential life-threatening ADEs, medication safety initiatives that ensure appropriate dosing of sotalol are necessary. Pharmacist-managed renal dosing assessment programmes ensure appropriate dosing of renally eliminated medications. A prospective medication safety evaluation was conducted to assess the need to include sotalol in an existing renal dosing assessment programme as well as the impact of clinical pharmacist assessment on sotalol prescribing. METHODS: Patients in a 736-bed community hospital, receiving sotalol during a 6-week period, were prospectively evaluated. Information was collected on indication, dosing, concomitant disease states and medications, renal function, QTc length, symptoms of toxicity and readmissions. Pharmacist recommendations were made when necessary and were followed to determine acceptance rate and patient outcomes. KEY FINDINGS: Thirty-six patients were prescribed sotalol for atrial tachyarrhythmias. Thirty-two (89%) were dosed inappropriately with respect to renal function. Twenty (56%) had left-ventricular dysfunction as defined by an ejection fraction of ≤ 40%. At time of initial assessment, 15 (42%) were exhibiting signs of potential sotalol toxicity. Pharmacists provided recommendations regarding discontinuation or dosage adjustment on 32 patients with a 38% full and a 12% partial acceptance rate. All-cause readmission rates for patients receiving appropriate therapy, including those after pharmacist recommendations were accepted (Group A; n=16), were compared to those remaining on inappropriate therapy (Group B; n=20). Readmission rates within 6 months differed between groups (31% for Group A, 55% for Group B; P=0.095, odds ratio 3.7). CONCLUSION: This medication safety evaluation suggests the need for pharmacist assessment in patients receiving sotalol. Dosage adjustment or avoidance in patients with renal insufficiency, heart failure and other relative contraindications is often necessary to avoid toxicity. Sotalol was inappropriately prescribed in the majority of patients secondary to renal insufficiency. Based on this evaluation, it was recommended to add sotalol to the institution's pharmacist-managed renal dosing adjustment programme. Ensuring clinical pharmacist assessment when sotalol is prescribed can help reduce potential life-threatening ADEs and hospital readmissions.
