ABSTRACT

BACKGROUND: Neutrophils expressing vascular endothelial growth factor receptor (VEGFR) represent a distinct subtype of neutrophils with proangiogenic properties. The purpose of this study was to identify the interrelations between circulating CD16^hiCD11b^hiCD62L^loCXCR2^hiVEGFR2^hi-neutrophils and indicators of carotid plaque burden in patients without atherosclerotic cardiovascular diseases (ASCVD).

METHODS: The study included 145 patients, 51.7% men and 48.3% women, median age-49.0 years. All patients underwent carotid duplex ultrasound scanning. The maximal carotid plaque thickness was used as an indicator of carotid plaque burden. Also, carotid intima-media thickness (cIMT) and femoral IMT were measured. The phenotyping of neutrophil subpopulations was executed by the flow cytometry via the Navios 6/2. Results. The subpopulation of VEGFR2^hi-neutrophils accounted for about 5% of the total pool of circulating neutrophils. A decrease in VEGFR2^hi-neutrophils with an increase in carotid plaque burden was statistically significant (p = 0.036). A decrease in VEGFR2^hi-neutrophils < 4.52% allowed to predict the presence of plaque with a maximum height > 2.1 mm (Q4), with sensitivity of 78.9% and specificity of 61.5% (AUC 0.693; 95% CI 0.575-0.811; p = 0.007). Inverse correlations were established between the carotid and femoral IMT and the absolute and relative number of VEGFR2^hi-neutrophils (p < 0.01).

CONCLUSION: In patients aged 40-64 years without established ASCVD, with an increase in indicators of the carotid plaque burden, a significant decrease in the proportion of circulating VEGFR2^hi-neutrophils was noticed. A decrease in the relative number of VEGFR2^hi-neutrophils of less than 4.52% made it possible to predict the presence of extent carotid atherosclerosis with sensitivity of 78.9% and specificity of 61.5%.

ABSTRACT

Introduction A history of fracture is a well-documented risk factor for sustaining future falls and subsequent fractures in geriatric patients. Orthopedic surgeons advocate various lifestyle modifications to reduce the risk of sustaining a recurrent fracture in this vulnerable group. However, it has been observed that patients seldom adhere to this advice and the rate of fragility fractures has thus continued to rise in this vulnerable subset of the population. The factors influencing the compliance of patients with various modifications have not been documented in any previous studies. In our study, we aimed to evaluate the factors influencing patient adherence to various lifestyle modifications advised by orthopedic surgeons for reducing future fracture risk. Material and methods A total of 112 patients aged >65 years who were diagnosed as having a peritrochanteric fragility fracture of the hip and were treated operatively for the same were included in this study. Upon discharge from the hospital, the patients were advised 10 lifestyle modifications to reduce the recurrent fracture risk. A data collecting form that graded the adherence on a 20-point scale (2 points for each lifestyle modification) was prepared by the investigators. Upon the six-month follow-up visit, adherence was assessed on the 20-point scale, and data were collected via the face-to-face interview method. Statistical analysis was accomplished by the Chi-square test and logistic regression analysis. Observations and results Of the 112 subjects included in the study, 58 (51.7%) were male and the mean age was 75 ± 8 (65 – 92) years. The adherence to less than 4 recommendations (Score <8) was seen in 39.2%, adherence to 4 – 6 recommendations (Score between 8 – 12) was seen in 30.86%, adherence to 6 – 8 recommendations (Score between 12 and 16) was seen in 29.94% and adherence to eight to 10 recommendations (score between 16 and 20) was seen in 0% of participants. According to the regression analysis, the presence of adherence to less than six recommendations was related to the low-income level (OR=0.298; 95%CI – 0.132-0.666; p<0.001) and lack of education and awareness (OR=2.329; 95% CI – 1.114-4.859; p=0.002). Conclusion The rates of adherence to advised lifestyle modifications were generally found to be low. Compliance was particularly reduced in patients belonging to the lower socioeconomic strata, which were less likely to be educated and had lower rates of income. The authors concluded that merely advising lifestyle modifications was not enough, and various social and public health measures are required to improve patient compliance, with the broader aim of ending the menace of recurrent fragility fractures.

ABSTRACT

Background Airway compromise and respiratory failure are feared complications of angioedema leading to intensive care unit (ICU) admission. However, few of these patients decompensate. There is a paucity of tools that predict airway compromise in patients with angioedema, and it is unclear if automatic triage to the ICU is warranted. We analyzed patients admitted to our tertiary center ICU with angioedema for “airway watch” to find a way to triage those at greatest risk of respiratory decompensation. Methods We performed a retrospective review of patients with angioedema admitted to our ICU between 2017 and 2020. Data collected included demographics, comorbidities, nasopharyngolaryngoscopy (NPL) findings, need for intubation, and length of stay. Descriptive analysis and subsequent ANOVA or T-test statistical analysis was performed to determine the relationships between individual variables and outcomes. Categorical variables were compared using Pearson’s Chi-squared test or Fisher’s exact test where applicable. Continuous variables were compared using a Mann-Whitney U test. Results Of 134 patients admitted to our ICU, 63 (47%) required intubation, primarily in the emergency department (92.1%). Of those who required intubation, 61.9% had abnormal NPL findings in contrast to 25.35% of patients who did not require intubation (p<0.0001). Normal NPL findings had a negative predictive value for requiring intubation of 86.5%. Abnormal NPL findings had a positive predictive value for requiring intubation of 68.4%. Conclusion While airway compromise is a serious complication of angioedema, there is scant evidence to support triage to the ICU for those not intubated immediately. The majority of patients with angioedema who required intubation had abnormal NPL findings, and the majority of those with normal NPL findings did not require intubation. This suggests that NPL findings in patients with angioedema can help with triage to the ICU.

ABSTRACT

BACKGROUND: Endoscopy is a rapidly developing discipline with new techniques and procedures being introduced each year. The consenting process is central to patient perception; using information videos as additional tools to aid consent and improve the quality of care in endoscopy is not well established. Our aim was to develop, implement and validate the use of patient educational videos to improve patients’ satisfaction and experience in endoscopy.

METHODS AND ANALYSIS: This was a prospective service quality improvement study. Eligible patients were invited to watch the educational videos in addition to standard practice. We compared this group with a matched cohort of patients who were receiving standard care of postal information leaflets. Patient satisfaction was measured through the validated Gastrointestinal Endoscopy Satisfaction Questionnaire (GESQ).

RESULTS: Patients in the intervention group scored four questions relating to pre-procedural information significantly higher than the control (p=0.038). The total mean GESQ score was also higher in the intervention group compared to the control, however this was not statistically significant (p=0.397). The intervention group had significantly lower cancellation rate (4%) compared to the control group (20%), p=0.023.

CONCLUSIONS: Patients who watched educational videos were more satisfied with pre-procedural information in the consenting period than those who did not. Further research is still needed to determine if they reduce patient anxiety. Meanwhile, it would be appropriate to implement these videos into routine practice as a cost-effective method of improving patient satisfaction.

ABSTRACT

Introduction Malignancy, tuberculosis, and non-tubercular pleural infections account for most exudative pleural effusion. Pleural fluid cytology, biochemical tests and even pleural fluid cell block studies may fail to yield a diagnosis in certain cases. Medical thoracoscopy is the gold standard for the diagnosis of unexplained pleural effusions. However, access to medical thoracoscopy may be limited, particularly in developing countries. Also, certain patients may not be fit to undergo the procedure because of medical conditions. An ultrasound-guided pleural biopsy is an option in such conditions. The present study is intended to compare the diagnostic yield and complications of both methods of pleural biopsy in undiagnosed exudative pleural effusion under a randomized controlled trial. Method After fulfilling all the inclusion criteria, participants were randomized to either ultrasound-guided closed pleural biopsy or thoracoscopic-guided pleural biopsy groups. The primary outcome was to compare the diagnostic yield of ultrasound-guided Tru-Cut® (Newtech Medical Devices, Faridabad, India) closed pleural biopsy versus thoracoscopic pleural biopsy, and the secondary outcomes were to compare the complications rate, duration of the procedure, and hospital stay in the patients undergoing ultrasound-guided pleural biopsy versus thoracoscopic pleural biopsy, and predictors of a positive biopsy result in both groups. Result A total of 118 patients with pleural effusion were screened; 39 of them who were eligible, randomized into the ultrasound group (20 patients) and the thoracoscopic group (19 patients). The median age of participants was 53.5 (50-58) years and 55 (45-64) years in the ultrasound and thoracoscopic groups, respectively. Pleural fluid cell count, protein, adenosine deaminase (ADA), and lactate dehydrogenase (LDH) were similar in both groups, although pleural fluid glucose was low in the ultrasound group. Diagnostic yield was 90% (18/20) and 94.7% (18/19) in the ultrasound and thoracoscopic groups, respectively, which was statistically non-significant (p=0.963). The median duration of hospital stay was 9.5 (5.3-27) days and 15 (12-22) days in ultrasound and thoracoscopic groups respectively. The thoracoscopic group had a more prolonged stay compared to the ultrasound group, but it was statistically non-significant (p=0.09). The duration of the procedure was significantly longer in the thoracoscopic group 90 (85-105) minutes, in comparison to ultrasound 47.5 (41.3-55) minutes (p=0.001). No major complications were seen in both groups. Subcutaneous emphysema was the most common complication in the thoracoscopic group (10%), followed by hemorrhage (5.3%), and respiratory failure (5.3%). Hypotension was the only complication in the ultrasound group (5%). The rate of complications was significantly higher in the thoracoscopic group (p<0.01). Conclusion Ultrasound-guided closed pleural biopsy is as good as thoracoscopic pleural biopsy in undiagnosed exudative pleural effusion. It was associated with a shorter procedure duration, a shorter hospital stay, and fewer complications as compared to thoracoscopic biopsy. Both the procedures were safe in experienced hands and a hospital setup, but the thoracoscopic pleural biopsy was associated with complications.

ABSTRACT

PURPOSE: Recent studies have focused on whether kidney injury molecule-1 (KIM-1) might serve as a marker of acute kidney tubular injury. Our study analyzed the levels of KIM-1 in the healthy population of different ages to explore the correlation between KIM-1 and age. Moreover, we constructed a model to predict kidney age.

METHODS: A cross-sectional study was conducted by Huashan Hospital, Shanghai, China, between April 2020 and December 2020. KIM-1 and other kidney biomarkers were measured in 176 healthy individuals ranging from 26 to 91 years old. Statistical correlated analyses for urinary KIM-1, creatinine (uCREA), potassium (K), sodium (Na) and chlorine (Cl), plasmic renin, angiotensin-2 (AngII) and aldosterone (ALD), and serum microalbuminuria (MALB), β2-microglobulin (B2MG), cystatin C (CYSC), urea nitrogen (BUN), creatinine (CREA), and glucose (GLU) were performed to assess the correlation between age and kidney biomarkers. All variables were selected as independent variables for the prediction of age by multiple linear regression.

RESULTS: KIM-1 positively correlated with age in kidney healthy people (r = 0.41, p < 0.05), whether among females (r = 0.51, p < 0.05) or males (r = 0.27, p < 0.05). It was much related to K (r = 0.34), B2MG (r = 0.28), and CL (r = 0.23). The predicted model was constructed with eGFR, Cl, ALD, CYSC, KIM-1, BUN, GLU and AngII, reaching an adjusted R² of 69.5% and a standard error of the estimated 7.84 years.

CONCLUSION: The level of urinary KIM-1 increases with age in healthy people. The model constructed by KIM-1 and the other 7 biomarkers can predict kidney age in healthy people.

ABSTRACT

The purpose of this study was to compare a periodized versus a non-periodized protocol of kettlebell (KTB) swings over six weeks on strength, power, and muscular endurance. Twenty-eight high intensity functional training (HIFT) practitioners were assigned to non-periodized (NPG = 11), periodized (PG = 11), or control groups (CG = 6). NPG used the same load (20 kg) throughout the training period while the PG used a step loading progression (with an added four kilograms every two weeks). Measures of strength and muscular endurance in the deadlift exercise, and power in the countermovement jump were assessed before and after six weeks. A two-way ANOVA was used to verify pre- to post-test differences in strength, power, and muscular endurance. An analysis of the effect size was also incorporated. For strength and power, statistical differences from pre- to post-test were found for both the NPG (p < 0.001; 1-RM improvement = 8.7%; jump height improvement = 8.7%) and PG (p < 0.001; 1-RM improvement = 7.8%; jump height improvement = 10.1%), with no difference between groups. For muscular endurance, only the PG showed significant differences from pre- to post-test (p = 0.013; muscular endurance improvement = 23.8%). In conclusion, when the goal is to increase strength and power performances in HIFT practitioners, periodized and non-periodized KTB models appear to be equally effective, and this can simplify the strength coach’s practice in programming KTB swing training periods. For muscular endurance, the addition of KTB swing on a periodized basis seems to be a more effective strategy.

ABSTRACT

To test the equality of several independent multinomial distributions, the chi-square test for count data is applied. The existing test can be applied when complete information about the data is available. The complex process, such as DNA count, the existing test under classical statistics may mislead. To overcome the issue, the modification of the chi-square test for multinomial distribution under neutrosophic statistics is presented in this paper. The modified form of the chi-square test statistic under indeterminacy/uncertainty is presented and applied using the DNA count data. From the DNA count data analysis, simulation, and comparative studies, the proposed test is found to be informative, springy, and good as compared with the existing tests.

ABSTRACT

BACKGROUND AND AIMS: Besides the crucial role in the treatment of acute ischemic stroke (AIS), mechanical thrombectomy represents a unique opportunity for researchers to study the retrieved clots, with the possibility of unveiling biological patterns linked to stroke pathophysiology and etiology. We aimed to develop a shotgun proteomic approach to study and compare the proteome of formalin-fixed paraffin-embedded (FFPE) cardioembolic and large artery atherosclerotic (LAA) clots.

METHODS: We used 16 cardioembolic and 15 LAA FFPE thrombi from 31 AIS patients. The thrombus proteome was analyzed by label-free quantitative liquid chromatography-tandem mass spectrometry (LC-MS/MS). MaxQuant v1.5.2.8 and Perseus v.1.6.15.0 were used for bioinformatics analysis. Protein classes were identified using the PANTHER database and the STRING database was used to predict protein interactions.

RESULTS: We identified 1,581 protein groups as part of the AIS thrombus proteome. Fourteen significantly differentially abundant proteins across the two etiologies were identified. Four proteins involved in the ubiquitin-proteasome pathway, blood coagulation or plasminogen activating cascade were identified as significantly abundant in LAA clots. Ten proteins involved in the ubiquitin proteasome-pathway, cytoskeletal remodeling of platelets, platelet adhesion or blood coagulation were identified as significantly abundant in cardioembolic clots.

CONCLUSION: Our results outlined a set of 14 proteins for a proof-of-principle characterization of cardioembolic and LAA FFPE clots, advancing the proteome profile of AIS human thrombi and understanding the pathophysiology of ischemic stroke.

ABSTRACT

BACKGROUND: Melanoma is the third most common skin cancer and the leading cause of skin cancer mortality. This study sought to investigate trends in melanoma incidence, mortality, and burden of disease.

METHODS: The authors assessed the records of the Global Burden of Disease Study 2017 to extract information about the incidence, mortality, and disability adjusted life years (DALY) related to melanoma during 1990-2017 in the US and other countries based on their socio-demographic index (SDI).

RESULTS: Melanoma incidence in the US increased 1.6 times, although the difference was not statistically significant. For patients over the age of 60, the incidence was significantly increased by 1.72 to 164.6 times. Mortality was relatively stable during the study period; however, it was increased for patients over 65 years of age (range: 1.03 to 70 times), although not statistically significant. Mortality-to-incidence ratio was decreased, but the difference was not statistically significant. For patients over 75 years of age, DALYs were statistically significantly increased by 1.34 to 1.71 times.

CONCLUSIONS: This study highlights differences in melanoma incidence and mortality from 1990-2017. Physicians involved in melanoma care should be aware of these changes in order to anticipate care needs.
