Objective: Few studies demonstrated the impairment of perceived emotional intelligence ‘EI’ among depressed patients. This study aimed to assess the perceived EI in a group of depressed patients, and its association with different clinical characteristics. Methods: Forty-five patients diagnosed with depression were assessed by the Hamilton Depression Rating Scale and compared to 45 controls that were assessed by the Arabic version of General Health Questionnaire to exclude Psychiatric disorders. The Arabic version of Trait Meta-Mood Scale (TMMS) is used to evaluate EI in both groups. Results: Patients with depression showed significantly lower EI scores in the three parts of TMMS (repair, clarity and attention) compared to the controls ( p < .001). Patients showed significant difference in clarity subscale ( p = .005) and attention regarding severity of depression ( p < .001). Clarity of feelings was significantly higher in patients who suffered more than two episodes ( p = .012). Depressive patients with suicidal attempts showed significantly lower scores of repair ( p = .044) and attention ( p = .016) subscales. There were no significant differences of TMMS subscales between patients with and without suicidal ideation, sleep disturbance and somatic symptoms. Conclusions: The current study demonstrates impaired perceived EI among patients with depression that is correlated with symptom severity and suicidal attempts.

Objective Bleeding and thrombosis are common complications during Extracorporeal Membrane Oxygenation (ECMO) support for COVID-19 patients. We sought to examine the relationship between inflammatory status, coagulation effects, and observed bleeding and thrombosis in patients receiving venovenous (VV) ECMO for COVID-19 respiratory failure. Study Design Cross-sectional cohort study Settings Quaternary care institution. Patients The study period from April 1, 2020, to January 1, 2021, we included all patients with confirmed COVID-19 who received VV ECMO support. Intervention None. Measurements and Main Results Thirty-two patients were supported with VV ECMO during the study period, and 17 patients (53%) survived to hospital discharge. The ECMO nonsurvivors mean lactate dehydrogenase (LDH) levels were markedly elevated in comparison to survivors (1046 u/L [IQR = 509, 1305] vs 489 u/L [385 658], p = 0.003). Platelet/fibrinogen dysfunction, as reflected by the low Maximum Amplitude (MA) on viscoelastic testing, was worse in nonsurvivors (65.25 mm [60.68, 67.67] vs 74.80 mm [73.10, 78.40], p = 0.01). Time-group interaction for the first seven days of ECMO support, showed significantly lower platelet count in the nonsurvivors (140 k/ul [103, 170] vs 189.5 k/ul [ 146, 315], p < 0.001) and higher D-dimer in (21 μg/mL [13, 21] vs 14 μg/mL [3, 21], p < 0.001) in comparison to the survivors. Finally, we found profound statistically significant correlations between the clinical markers of inflammation and markers of coagulation in the nonsurvivors group. The ECMO nonsurvivors experienced higher rate of bleeding (73.3% vs 35.3%, p = 0.03), digital ischemia (46.7% vs 11.8%, p = 0.02), acute renal failure (60% vs 11.8%, p = 0.01) and bloodstream infection (60% vs 23.5%, p = 0.03). Conclusion The correlation between inflammation and coagulation in the nonsurvivors supported with VV ECMO could indicate dysregulated inflammatory response and worse clinical outcomes.

Objective To evaluate the quantity of titanium dioxide nanoparticles released into the artificial salivary medium from orthodontic composite impregnated with 1% weight/weight (w/w) and 5% w/w titanium dioxide nanoparticles (TiO2 NPs) used for bonding metal brackets, thereby eventually comprehending the permissible levels. Materials and Method Eighty freshly extracted teeth for orthodontic treatment were divided into 2 groups of 40 teeth each and were bonded with brackets containing 1% w/w and 5% w/w composite containing titanium dioxide nanoparticles and placed in an artificial salivary medium. Quantification of 1% w/w and 5% w/w composite containing titanium nanoparticles was done using inductively coupled plasma mass spectroscopy for 4 timely periods 24 h, 2 months, 4 months, and 6 months. Results In the teeth that received 1% TiO2, the amount of titanium released was greatest in 2 months with no significant release at later intervals. In the second group that received 5%, there was a significant release of titanium at all intervals, with highest release at second month. On comparing the 2 concentrations at 4 different time intervals, the quantities were significantly greater in the 5% group at all time frames, thus implying a significant increase in titanium released with an increase in concentration from 1% to 5%. Conclusion Titanium release was higher in 5% w/w composite containing nanoparticles than 1% w/w composite containing nanoparticles, and 1% and 5% concentrations can be used safely and are within the permissible limits.

Background: Current consensus and position statements recommend that concussed patients be asymptomatic upon the initiation of the graduated return to activity (RTA) protocol. However, a significant number of concussed patients are beginning their RTA protocols while endorsing symptoms. Purpose: To characterize symptom endorsement at the beginning of the RTA protocol and examine the association between symptom endorsement and RTA protocol duration in service academy cadets. Study Design: Cohort study; Level of evidence, 2. Methods: A prospective cohort study was conducted with cadets at 3 US service academies. Postconcussion symptom inventories were recorded upon the initiation of an RTA protocol. The Sport Concussion Assessment Tool Symptom Inventory was used to classify participants into 3 groups (0 symptoms, 1 symptom, and ≥2 symptoms) upon the initiation of the RTA protocol. The primary outcome of interest was RTA protocol duration. Kaplan-Meier survival estimates were calculated to estimate RTA protocol duration by symptom endorsement, sex, varsity status, academic break, and time to graduated RTA initiation. Univariate and multivariable Cox proportional hazards models were used to estimate the association between symptom endorsement at the initiation of the RTA protocol and RTA protocol duration (α < .05). Results: Data were analyzed from 966 concussed cadets (36% women). Headache (42%) and faintness/dizziness (44%) were the most commonly endorsed symptoms on the Sport Concussion Assessment Tool-Third Edition and the Brief Symptom Inventory-18, respectively. Univariate results revealed a significant association between endorsing ≥2 symptoms and RTA protocol duration. In the multivariable model, endorsing ≥2 symptoms maintained a statistically significant association with RTA protocol duration. Significant associations were observed between RTA protocol duration and nonvarsity status (27% longer), women (15% longer), academic breaks (70% longer), and time to the initiation of the RTA protocol (1.1% longer daily incremental increase) after controlling for covariates. Conclusion: Symptom endorsement at the initiation of an RTA protocol was associated with RTA protocol duration. Cadets who had returned to preinjury baseline symptom burden or improved from baseline symptom burden and endorsed ≥2 symptoms at the initiation of the RTA protocol took longer to RTA.

Background: Biomechanical predictors of pitching accuracy are underevaluated in baseball research. It is unclear how pitchers with higher accuracy differ in terms of kinematics and upper extremity kinetics. Purpose: To differentiate high- and low-accuracy professional pitchers by full-body kinematic and upper extremity kinetic parameters. Study Design: Descriptive laboratory study. Methods: In total, 121 professional baseball pitchers threw 8 to 12 fastballs while assessed with motion-capture technology (480 Hz). Pitchers were divided into high-accuracy (n = 33), moderate-accuracy (n = 52), and low-accuracy (n = 36) groups based on the absolute center deviation of each pitcher’s average pitch to the center of the pitching chart by greater or less than 0.5 SD from the mean, respectively. The 95% confidence ellipses with comparisons of major and minor radii and pitching probability density grids were constructed. Analysis of variance was used to compare kinematic and kinetic values between groups. Results: The absolute center deviation (14.5% ± 6.7% vs 33.5% ± 3.7% grid width; P < .001) was significantly lower in the high-accuracy compared with the low-accuracy group, with no significant difference in ball velocity (38.0 ± 1.7 vs 38.5 ± 2.0 m/s; P = .222). Lead knee flexion at ball release (30.6°± 17.8° vs 40.1°± 16.3°; P = .023) was significantly less for the high-accuracy pitchers. Peak normalized shoulder internal rotation torque (5.5% ± 1.0% vs 4.9% ± 0.7% body weight [BW] × body height [BH]; P = .008), normalized elbow varus torque (5.4% ± 1.0% vs 4.8% ± 0.7% BW × BH; P = .008), and normalized elbow medial force (42.9% ± 7.3% vs 38.6% ± 6.2% BW; P = .024) were significantly greater for the low-accuracy group compared with the high-accuracy group. Conclusion: Professional pitchers with increased accuracy experienced decreased throwing arm kinetics. These pitchers had increased lead knee extension at later stages of the pitch, potentially providing more stable engagement with the ground and transference of kinetic energy to the upper extremities. Professional pitchers can consider increasing lead knee extension at the final stages of the pitch to improve the accuracy of their throws and mitigate elbow varus torque. Clinical Relevance: Increased elbow varus torque, shoulder internal rotation torque, and elbow medial force in less accurate pitchers may contribute to increased injury risk in this group.

Published: January 2022

Objective: Magnetic stimulation (MS) provides a novel strategy for the treatment of urinary incontinence (UI), although its efficacy remains uncertain. This systematic review both evaluated the effects of MS treatment on UI and investigated its impacts on female patients’ life quality. Methods: A review of the literature that was conducted in EMBASE, PubMed, Google Scholar, and the Cochrane Library (2016–2021) with the search terms; Incontinence of stress OR urge of urination OR Urinary incontinence mixed type. The search was carried out for all randomised controlled trials (RCTs) in English. A manual search has also been conducted for the reference lists of the studies found. Seven studies, with a total of 523 patients (475 patients with SUI), 12 urge urinary incontinence. The study included patients with (UUI) and 36 patients with mixed urinary incontinence (MUI). A total of 10 male patients were excluded from the study. In the included studies, The International Incontinence Questionnaire-Short Form was used to investigate the effects of MS therapy on UI symptoms (ICIQ-SF). Results: According to the literature review, MS is an effective therapy option for female patients with UI. Still, to establish the efficacy of MS in this area, more large-scale, high-quality RCTs with extended follow-up periods that use consistent stimulation modalities and evaluate comparable outcomes are needed. Conclusion: MS treatment leads to an improvement in the symptoms of UI, in addition to an associated Improved quality of life for patients, without any reported side effects, while the longer-term treatment outcomes must be determined by long-term trials.

Objective Dying in the intensive care unit (ICU) has changed over the last twenty years due to increased utilization of palliative care. We sought to examine how palliative medicine (PM) integration into critical care medicine has changed outcomes in end of life including the utilization of do not resuscitate (no cardiopulmonary resuscitation but continue treatment) and comfort care orders (No resuscitation, only comfort medication). Design: Retrospective observational review of critical care patients who died during admission between two decades, 2008 to 09 and 2018 to 19. Setting: Single urban tertiary care academic medical center in Washington, D.C. Patients: Adult patients who were treated in any ICU during the admission which they died. Interventions and Measurements We sought to measure PM involvement across the two decades and its association with end of life care including do not resuscitate (DNR) and comfort care (CC) orders. Main Results: 571 cases were analyzed. Mean age was 65 ± 15, 46% were female. In univariate analysis significantly more patients received PM in 2018 to 19 (40% vs. 27%, p = .002). DNR status increased significantly over time (74% to 84%, p = .002) and was significantly more common in patients who were receiving PM (96% vs. 72%, p < 0.001). CC also increased over time (56% to 70%, p = <0.001), and was more common in PM patients (87% vs. 53%, p < 0.001). Death in the ICU decreased significantly over time (94% to 86%, p = .002) and was significantly lower in PM patients (76% vs. 96%, p < 0.001). The adjusted odds of getting CC for those receiving versus those not receiving PM were 14.51 (5.49-38.36, p < 0.001) in 2008 to 09 versus 3.89 (2.27-6.68, p < 0.001) in 2018 to 19. Conclusion: PM involvement increased significantly across a decade in our ICU and was significantly associated with incidence of DNR and CC orders as well as the decreased incidence of dying in the ICU. The increase in DNR and CC orders independent of PM over the past decade reflect intensivists delivering PM services.

This study proposes a downstream single-row air washer for air cooling. The theoretical energy and exergy balance models were established at different droplet diameters and verified by the experimental data. Based on the abovementioned theoretical relationship, the single performance indicator of heat exchange efficiency (HEE) and exergy efficiency was quantitatively analyzed; a comprehensive analysis method of two indicators was proposed, combining HEE and exergy efficiency, and a numerical simulation was carried out. Results show that the smaller the droplet diameter and the larger the water–air ratio, the lower the dry-bulb temperature of the outlet air and the higher the HEE and exergy flux destruction. When the droplet diameter is less than 440 μm, the droplet diameter does not affect exergy efficiency and dry-bulb temperature. When the droplet diameter is larger than 440 μm, the droplet diameter is positively correlated with the air outlet dry-bulb temperature and exergy efficiency; in contrast, the water–gas ratio is negatively correlated with the air outlet dry-bulb temperature. An engineering case reveals that when the air outlet temperature is less than 34°C, the critical water–gas ratio can be set as 2.6 (mass ratio). At this time, the HEE is more than 90%, the exergy efficiency is more than 60%, and the critical value of droplet diameter is 440 μm. The research results provide an essential theoretical basis for the optimization of engineering design calculation.

Objectives Vitamin D deficiency has been observed in autoimmune rheumatic diseases, such as rheumatoid arthritis. The aim was to study vitamin D in patients with systemic lupus erythematosus (SLE) and its relationship with disease activity. Methods In a cohort of 45 patients with SLE, 41 females and 4 males, aged 47.07 ± 2.17 years (mean ± SEM), and range = 21–79 years, 25(OH)D3 levels were determined by electrochemiluminescence. C3 and C4 levels were also analyzed. SLE disease activity was estimated by SLEDAI-2K. Observations were also performed in a control group matched for age and sex. Results In this cohort of SLE patients, 25(OH)D3 levels were 40.36 ± 2.41 nmol/L (mean ± SEM) as opposed to 60.98 ± 4.28 nmol/L in the control group ( p < 0.001, Student’s t test). Vitamin D levels were related to C3 ( p < 0.001, linear regression analysis), correlation coefficient 0.106, r2 = 0.011, and C4 ( p < 0.001); correlation coefficient 0.316 and r2 = 0.100; and inversely related to disease activity ( p < 0.001), correlation coefficient −0.572 and r2 = 0.327. 25(OH)D3 levels were 17.73 ± 1.20 nmol/L and 12.24 ± 0.93 nmol/L, in the groups without and with renal involvement, respectively ( p = 0.001, Student’s t test). Conclusions Vitamin D levels are low in SLE patients and are inversely related to disease activity. Routine screening for vitamin D levels should be performed in SLE patients.

Background Colorectal cancer defined as cancer of the colon or rectum, is the third most frequently diagnosed cancer in men and the second in women, and, according to the World Health Organization database GLOBOCAN, it accounts for nearly 1.4 million new cases annually worldwide. The occurrence of colorectal cancer is associated with nonmodifiable risk factors, including age and hereditary factors, as well as with modifiable environmental and lifestyle factors. Methods The study included 800 patients, 400 diagnosed with colorectal cancer and 400 within the control group, who gave their written informed consent to participate in the study. Patients with cancer other than colorectal cancer were randomly selected for control group I, and patients with no cancer diagnosis were selected for control group II. The method used was a case-control study – an observational and analytical study with a control group, conducted among patients of the Clinical Oncology Centre and the Provincial Hospital in the years 2019–2020. The study comparing the exposure was carried out in a group of people who developed the endpoint, that is colorectal cancer, with the exposure in a well-matched group of controls who did not reach the endpoint. Assessment of activity and BMI was used according to WHO recommendations, as well as the expert system. The data were tested for the distribution and the homogeneity of variance was validated before applying the parameter tests. Comparison of quantitative variables between groups was performed using ANOVA. Results The mean age of the patients was 64.53 ± 8.86 years, of the control group I – 59.64 ± 9.33 and the control group II – 57.5 (7.83). There was a strong positive association between the incidence of ulcerative colitis and the risk of colorectal cancer ( P < .01). Among obese subjects, the risk of developing colorectal cancer was 1.27 (95% CI, 1.06–1.53) compared with nonobese subjects. A strong positive relationship was found between low physical activity converted to metabolic equivalent of MET effort per week and the risk of colorectal cancer ( P < .001). The relative risk for current smokers was 2.17 (95% CI 1.79–2.66). There was an association between higher fat consumption and higher red meat consumption and the risk of developing colorectal cancer ( P < .01). Conclusions Obesity, low physical activity, active and passive smoking and high salt and red meat consumption have been associated with an increased risk of colorectal cancer. These findings provide further evidence of the importance of maintaining a healthy lifestyle.

Published: January 2022

Data is limited on the immunogenicity of the COVID-19 two-vaccination series among patients with hematologic malignancies and current guidelines do not recommend routine monitoring for post-vaccine antibodies. However, we describe three patients who developed severe or critical COVID-19 infections six months after vaccination. This highlights the importance of routine testing of COVID-19 IgG Spike, semi-quantitative antibodies post-vaccination, particularly among immunocompromised patients.
