Objective: Pregnancy can induce the slowing of blood flow in the lower extremity veins and associated complications such as varicose veins. The objective of this study was to report the hemodynamic alterations in uncomplicated pregnancies during second and third trimesters using spectral Doppler. The specific aim was to compare the venous diameter and mean flow velocities of maternal common femoral veins (CFVs) during second and third trimesters of pregnancy. This was designed to assess the extent of pregnancy-induced hemodynamic changes as well as to establish a normative range of these values. Materials and Methods: This cohort study was conducted with 230 women during second and third trimesters of pregnancy. Grayscale sonography and spectral Doppler were used to record the diameter and mean flow velocity of maternal CFVs bilaterally. An independent sample t test was performed for the comparison of these between women with second and third trimesters of pregnancy. Statistical significance was set a P ≤ .05, a priori. Results: There was significant dilatation and a corresponding decrease in mean blood flow velocities in the CFVs in the participants in their third trimester compared with the second trimester of pregnancy. Conclusion: In this large cohort of participants, the CFV demonstrated statistically significant distension and slowing of blood flow with the advancement of their pregnancies.

Objective: The aim was to explore the existence of health care leadership gaps in communication, which occurred during the COVID-19 pandemic, by utilizing a qualitative research approach. Materials and Methods: Participants were recruited from a single professional organization. The volunteer leadership group was the frame for recruiting study participation. This work was conducted with a flexible research design method. A demographic survey, interview guide, and data triangulation survey were used to collect data from 21 participants over a four-week period. The participant responses were then analyzed through a process of coding and thematic analysis. Results: Five themes were generated from this cohort’s data, which alluded to gaps in leadership communication. These gaps occurred in the leader/employee relationship, at their respective institutions. Triangulation of the data from surveys underscored the presence of these communication gaps. Conclusion: The findings of this study may suggest the importance of a set of communication competencies for those in health care leadership, regardless of the complexities of a pandemic.

Objective: Diabetes mellitus (DM) and hypertension are among the most common causes of arteriosclerotic diseases. Intima-media thickness is usually increased with arterial diseases and an increase in carotid intima-media thickness (cIMT) is associated with the presence and extent of coronary artery disease (CAD). This study was designed to sonographically compare the cIMT in hypertensive and DM patient volunteers. Materials and Methods: A case-control stratified study was conducted at Lahore imaging center. Patients were invited to the study had to more than 30 years of age, DM, and hypertension. Individuals from the same age group without hypertension and DM were invited as study controls. Patients with an endarterectomy, or other arterial interventional procedure, as well as a previous history of cardiovascular disease and stroke, were excluded. Results: The mean cIMT, within the right carotid artery was 0.53 mm for the control group, 0.69 mm for the DM group, 0.67 mm for the hypertensive group, and 0.98 mm for the DM and hypertensive patients. The mean cIMT of the left carotid artery was 0.56 mm for the control group, 0.7 mm for DM group, 0.68 mm for hypertensive group, and 1.01 mm for the DM and hypertensive patients. Conclusion: There was a significant difference between the mean cIMT among DM and non-DM individuals. The control group and the DM or hypertension group also differed significantly. However, a more significant difference was found in the mean cIMT within the common carotid artery of control group as well as those with both DM and hypertension.

Varied diagnostic imaging techniques may often be used in tandem, to enhance and complement each other, when an initial imaging diagnosis appears equivocal. Diagnostic medical sonography and magnetic resonance imaging (MRI) are imaging techniques that often complement each another. Sonography is an excellent diagnostic technique to determine the consistency of a soft tissue mass (e.g., solid vs cystic), and its relationship to adjacent structures, size, and shape. Sonography is especially useful for evaluating palpable lumps and allows sonographers to perform targeted examinations around the area of interest. In addition, color and pulsed-wave Doppler enable further characterization of a lesion’s presence or lack of vascularity. Sonography can also guide core-needle biopsy of superficial lesions. However, sonography is less reliable for deep masses in large anatomical regions. The American College of Radiology recommends MRI for deeper lesions of this type. Magnetic resonance imaging is also recommended for soft tissue masses suspected to be localized to the peripheral nervous system.

Objective: Explore the differing associations of Sonography Work Systems (SWS) model factors with work-related discomfort outcomes among sonographers in four sonographic practice areas. Materials and Methods: Survey data from a national cross-disciplinary cohort of sonographers was analyzed to explore experiences of work factors and work-related discomfort in sonographers across four practice areas: abdominal (ABD+), adult echocardiography (Echo), obstetrics/gynecology (OB/GYN), and vascular technology (VT). One-way analyses of variance (ANOVAs) and chi-square tests were conducted on SWS factors and work-related discomfort to examine differences across practice area groups. Associative analyses were conducted between upper extremity musculoskeletal discomfort and hand used during sonography examinations. For each practice group, regression analyses examined associations of SWS factors with work-related discomfort (i.e., musculoskeletal and visual discomfort, headaches). Results: 2924 survey respondents (n = 1747 ABD+, n = 519 Echo, n = 351 VT, and n = 307 OB/GYN) were identified. Descriptive differences were identified in SWS factors and discomfort across practice area groups. Significant differences were noted in distribution of upper extremity pain compared with the hand used to complete sonography examinations ( P < .001). Conclusion: This study identified multiple organizational, tool, and process factors commonly associated with discomfort across specialties, which underscores the need for multidimensional approaches to worker health that include effective administrative and engineering controls.

Objective: This study was designed to explore the teaching self-efficacy, by clinical preceptors instructing sonography students, in bachelor’s degree-accredited sonography programs. Materials and Methods: A survey was provided to sonography clinical preceptors, to gauge their level of teaching self-efficacy. The survey instrument, Sonography Preceptor Teaching Self-Efficacy Inventory (SPTSEI) was used. The intent of the survey was to gauge, holistically, sonography preceptors’ perceptions of influencing student learning, in a clinical setting. Results: The survey respondents suggested that they had a high level of confidence in their skill to transmit knowledge and abilities to students. However, it was found that preceptors who had received some type of professional development, as preceptor, had a statistically significant higher level of teaching self-efficacy than those who had not received any type of training. Conclusion: Clinical preceptors are skilled health care professionals in their chosen discipline but may have little to no teaching experience. If preceptors do not fully understand their role in the educational process, both they and their students may not attain educational goals. It is therefore critically important that proper training and education, to support clinical preceptors, be provided for them. This survey would suggest that clinical preceptors, with training, can better perform their educational roles and better handle any challenges that might arise, as a part of providing clinical education.

Objective: This study was designed to use sonography and evaluate arteriovenous fistulas (AVFs) in dialysis patients. The aim was to determine criteria for distinguishing between patent AVFs with proper function (healthy) and unhealthy AVFs. Materials and Methods: This study enrolled 106 dialysis patients with an AVF. All fistulas were evaluated using spectral Doppler and grayscale sonography, assessing parameters such as draining vein diameter, distance of the venous vein from the skin surface, feeding artery diameter, presence of thrombosis, and fistula stenosis. Subsequently, Doppler criteria such as flow volume (FV) and resistance index (RI) were measured and compared between healthy and unhealthy AVFs. Results: This cohort’s spectral Doppler findings demonstrated lower FV and higher RI, in unhealthy AVFs, compared to healthy ones (283.5 ± 101.26 mL/min vs 1383.43 ± 756.76 mL/min; P = .006) and (0.55 ± 0.33 vs 0.37 ± 0.14; P = .004) respectively. Conclusion: The spectral Doppler and grayscale sonographic imaging made it possible to evaluate AVF performance and determine its quality. In this cohort, a decreased FV, increased RI, and decreased draining vein diameter were observed in unhealthy AVFs. These results would suggest that sonographers and clinicians should pay close attention to these parameters when assessing the function of an AVF, for patients undergoing hemodialysis.
目的:应用超声技术评价透析患者的动静脉瘘(avf)。目的是确定区分功能正常(健康)的专利avf和不健康的avf的标准。材料和方法:本研究纳入106例AVF透析患者。所有瘘管均采用频谱多普勒和灰度超声进行评估，评估引流静脉直径、静脉与皮肤表面的距离、供血动脉直径、血栓形成情况和瘘管狭窄等参数。随后，测量多普勒标准，如流量(FV)和阻力指数(RI)，并比较健康和不健康avf之间的差异。结果:该队列的频谱多普勒结果显示，与健康的avf相比，不健康的avf的FV较低，RI较高(283.5±101.26 mL/min vs 1383.43±756.76 mL/min;P = 0.006)和(0.55±0.33 vs 0.37±0.14;P = .004)。结论:超声多普勒和灰度成像技术可以评价AVF的性能，确定其质量。在这个队列中，在不健康的avf中观察到FV降低、RI增加和引流静脉直径减小。这些结果提示超声医师和临床医生在评估血液透析患者的AVF功能时应密切关注这些参数。
