ABSTRACT

OBJECTIVE: This study aimed to determine the thoracic and extra-thoracic extension of the disease in patients diagnosed with lung cancer and who had whole-body F18-fluorodeoxyglucose positron emission tomography/CT imaging and to investigate whether there is a relationship between tumor size and extrathoracic spread.

METHODS: A total of 308 patients diagnosed with lung cancer were included in this study. These 308 patients were first classified as group 1 (SPN 30 mm>longest lesion diameter ≥10 mm) and group 2 (lung mass (longest lesion diameter ≥30 mm), and then the same patients were classified as group 3 (nodular diameter of ≤20 mm) and group 4 (nodular size of >20 mm). Group 1 was compared with group 2 in terms of extrathoracic metastases. Similarly, group 3 was compared with group 4 in terms of frequency of extrathoracic metastases. F18 fluorodeoxyglucose positron emission tomography/CT examination was used to detect liver, adrenal, bone, and supraclavicular lymph node metastasis, besides extrathoracic metastasis.

RESULTS: Liver, bone, and extrathoracic metastasis in group 1 was statistically lower than in group 2 (p<0.001, p<0.01, and p=0.03, respectively). Liver, extrathoracic, adrenal, and bone metastasis in group 3 was statistically lower than that in group 4 (p<0.001, p=0.01, and p=0.04, p<0.01, respectively). The extrathoracic extension was observed in only one patient in group 3. In addition, liver, adrenal, and bone metastases were not observed in group 3 patients.

CONCLUSION: Positron emission tomography/CT may be more appropriate for cases with a nodule diameter of ≤20 mm. Performing local imaging in patients with a nodule diameter of ≤20 mm could reduce radiation exposure and save radiopharmaceuticals used in positron emission tomography/CT imaging.

ABSTRACT

OBJECTIVE: This study aimed to evaluate occlusion development after premature loss or extraction of deciduous anterior teeth, by means of a prospective cohort study.

METHODS: Fifteen infants and children aged 1 to 5 years old were longitudinally assessed (with loss or extraction of deciduous anterior teeth [n = 9], and without tooth losses [n = 6]). Photographs and dental casts at the baseline and after 24 months of follow-up were performed. Dental casts were scanned, and linear measurements were made on the digitalized models (missing tooth space, arch perimeter, arch length, arch width, intercanine length and intercanine width). The t-test was used for groups comparisons (α = 0.05).

RESULTS: Individuals’ mean age at baseline was 2.93 (± 1.18) years. No statistically significant differences were observed in the missing tooth space in the group with tooth loss during the 24 months of follow-up (p > 0.05). Arch perimeter, arch length, arch width, intercanine length and intercanine width did not show differences between the groups (p > 0.05). Qualitative photographic evaluation revealed other changes in the dental arches and occlusion, such as exfoliation and eruption of deciduous teeth, eruption of permanent teeth, self-correction or establishment of malocclusion, among others.

CONCLUSION: The results suggest that the premature loss of deciduous anterior teeth does not affect the perimeter, length and width of the dental arches; however, other alterations that lead to malocclusion could be established.

ABSTRACT

BACKGROUND: Cancer screening is absolutely necessary in patients with pericardial effusion, given that cancer is one of the most serious diseases in the etiology of pericardial effusion. In previous studies, it was stated that the systemic immune-inflammation index (SII); the prognostic nutrition index (PNI); and the hemoglobin, albumin, lymphocyte, platelet (HALP) score can produce scores related to cancer.

OBJECTIVES: This study began considering that these scoring systems could predict cancer in the etiology of patients with pericardial effusion.

METHODS: This study produced a retrospective analysis of patients who underwent pericardiocentesis between 2006 and 2022. Pericardiocentesis was performed in a total of 283 patients with moderate-to-large pericardial effusion or pericardial tamponade within the specified period. HALP, PNI, and SII scores were calculated according to the peripheral venous blood taken before the pericardiocentesis procedure. The statistical significance level was set at p<0.05.

RESULTS: The HALP score proved to be 0.173 (0.125-0.175) in cancer patients and 0.32 (0.20-0.49) in non-cancer patients (p<0.001). The PNI score proved to be 33.1±5.6 in cancer patients and 39.8±4.8 in non-cancer patients (p<0.001).

CONCLUSION: The HALP score and PNI proved to be easy and fast cancer screening tests that can predict cancer metastasis in the etiology of patients with pericardial effusion.

ABSTRACT

BACKGROUND: Untreated multivessel disease (MVD) in acute myocardial infarction (AMI) has been linked to a higher risk of recurrent ischemia and death within one year . Current guidelines recommend percutaneous coronary intervention (PCI) for significant non-infarct artery (-ies) (non-IRA) stenosis in hemodynamically stable AMI patients with MVD, either during or after successful primary PCI, within 45-days. However, deciding the timing of revascularization for non-IRA in cases of MVD is uncertain.

METHODS: This meta-analysis was performed based on PRISMA guidelines after registering in PROSPERO (CRD42023472652). Databases were searched for relevant articles published before 10 November 2023. Pertinent data from the included studies were extracted and analyzed using RevMan v5.4.

RESULTS: Out of 640 studies evaluated, there were 13 RCTs with 5144 patients with AMI with MVD. The immediate non-IRA PCI is associated with a significantly lower occurrence of unplanned ischemia-driven PCI (OR 0.60; confidence interval [CI] 0.44-0.83) and target-vessel revascularization (OR 0.72; CI 0.53-0.97) . Although there is a favorable trend for major adverse cardiovascular and cerebrovascular events (MACCE), nonfatal AMI, cerebrovascular events, and major bleeding in the immediate non-culprit artery (-ies) PCI, those were statistically non-significant. Similarly, all-cause mortality, cardiovascular mortality, stent thrombosis, and acute renal insufficiency did not show significant differences between two groups.

CONCLUSION: Among hemodynamically stable patients with multivessel AMI, the immediate PCI strategy was superior to the multistage PCI strategy for the unplanned ischemia-driven PCI and target-vessel revascularization while odds are favorable in terms of MACCE, nonfatal AMI, cerebrovascular events, and major bleeding at longest follow-up.

ABSTRACT

The IndieTrainer system, consisting of a mobility device and video-based gamified training modules, was developed to assist children in attaining power wheelchair (PWC) skills. The purposes of this small-scale trial were to explore the use of the IndieTrainer system to provide PWC skills training and document parental satisfaction with the IndieTrainer system. We hypothesized that PWC skills training provided using the IndieTrainer system would result in improvements in both children’s understanding of how to use a PWC and their PWC skill execution, and that parental satisfaction would be high. An open-label, single-arm trial was conduct as follows: (a) Baseline testing (T0); (b) A 3-week intervention consisting of two, 60-min-PWC skills training sessions per week; (c) Post-intervention testing (T1); and (d) A single session retention trial held 4 weeks after completion of the intervention (T2). Outcome measures included the Assessment of Learning Powered mobility use (ALP), Wheelchair Skills Checklist (WSC), Canadian Occupational Performance Measure (COPM), and Client Satisfaction Questionnaire-8 (CSQ-8). 25 child/parent dyads participated. Between T0 and T1, statistically significant differences (p-value <.0001) with large effect sizes in mean ALP and WSC scores (ALP: d = 3.14; WSC: d = 3.25) and COPM performance and satisfaction scores (Performance: d = 4.66; Satisfaction: d = 3.24) were achieved. Mean T1 total CSQ-8 score was 31.52/32. At T2, all children maintained or improved their T1 ALP and WSC scores. This study provides initial support for the usability and feasibility of the IndieTrainer system. Futhermore, larger scaled studies using more rigorous research designs are indicated.

ABSTRACT

STUDY DESIGN: Retrospective Review.

OBJECTIVE: The purpose of this study was to evaluate disparities in patient reported outcome measures (PROM) completion rates and baseline function scores among newly presenting spine patients.

SUMMARY OF BACKGROUND DATA: Prior studies have demonstrated that minority patients and those of low socioeconomic status may present with worse physical and mental health on PROMs. As PROMs are increasingly used in clinical care, research, and health policy, accurate assessment of health status among populations relies on the successful completion of PROM instruments.

METHODS: A retrospective review of 10,803 consecutive new patients presenting to a single multidisciplinary spine clinic from June 2020 to September 2022 was performed. Univariate statistics were performed to compare demographics between patients who did and did not complete PROMs. Multivariable analysis was used to compare PROM instrument completion rates by race, ethnicity, and Social Vulnerability Index (SVI) and baseline scores among responders.

RESULTS: 68.4% of patients completed PROMs at the first clinic visit. After adjusting for age, sex, body mass index, and diagnosis type, patients of non-white race (OR=0.661, 95%-CI=0.599-0.729, P<0.001), Hispanic ethnicity (OR=0.569, 95%-CI=0.448-0.721, P<0.001), and increased social vulnerability (OR=0.608, 95%-CI=0.511-0.723, P<0.001) were less likely to complete PROMs. In the multivariable models, patients of non-white race reported lower levels of physical function (β=-6.5, 95%-CI=-12.4 to -0.6, P=0.032) and higher levels of pain intensity (β=0.6, 95%-CI=0.2-1.0, P=0.005). Hispanic ethnicity (β=1.5, 95%-CI=0.5-2.5, P=0.004) and increased social vulnerability (β=1.1, 95%-CI=0.4-1.8, P=0.002) were each associated with increased pain intensity.

CONCLUSION: Among newly presenting spine patients, those of non-white race, Hispanic ethnicity, and with increased social vulnerability were less likely to complete PROMs. As these subpopulations also reported worse physical function or pain intensity, additional strategies are needed to better capture patient reported health status in order to avoid bias in clinical care, outcomes research and health policy.

ABSTRACT

BACKGROUND: We proposed an artificial-pancreas-like algorithm (AP-A) which could automatically determine the pre-prandial insulin dose based on intermittently scanned continuous glucose monitoring (isCGM) data trajectories in multiple dose injection (MDI) therapy. We aim to determine whether pre-prandial insulin dose adjustments guided by the AP-A is as effective and safe as physician decisions.

METHODS: We performed a randomized, single-blind, clinical trial at a tertiary, referral hospital in Beijing, China. Type 2 diabetes participants were eligible if they were aged 18 years, with a glycated hemoglobin of 8.0% or higher. Eligible participants were randomly assigned (1:1) to the AP-A arm supervised by physician and the conventional physician treatment arm. The primary objective was to compare percentage time spent with sensor glucose level in 3.9-10.0 mmol/L (TIR) between the two study arms. Safety was assessed by the percentage time spent with sensor glucose level below 3.0 mmol/L (TBR).

RESULTS: 140 participants were screened, of whom 119 were randomly assigned to AP-A arm (n = 59) or physician arm (n = 60). The TIR achieved by the AP-A arm was statistically non-inferior compared with the control arm (72.4% (63.3-82.1) vs. 71.2% (54.9-81.4)), with a median difference of 1.33% (95% CI, -6.00 to 10.94, non-inferiority margin -7.5%). TBR was also statistically non-inferior between the AP-A and control arms (0.0% (0.0-0.0) vs. 0.0% (0.0-0.0), respectively; median difference (95% CI, 0.00% (0.00 to 0.00), non-inferiority margin 2.0%).

CONCLUSIONS: The AP-A supported physician titration of pre-prandial insulin dosage offers non-inferior glycemic control compared with optimal physician care in type 2 diabetes.

ABSTRACT

BACKGROUND: Handgrip strength is a crucial indicator of upper extremity muscular strength and is vital for monitoring disorders like cardiac diseases that restrict a patient’s physical activity and result in muscle atrophy. The aim of our study was to evaluate whether muscle strength loss is present in patients with pulmonary hypertension and whether this test can be an alternative to 6-minute walk test.

MATERIALS AND METHODS: The study included 39 healthy children who were admitted to the outpatient clinic and 16 children with a diagnosis of pulmonary hypertension who were being followed in our centre. We assessed the differences in upper extremity handgrip strength using the Jamar Hydraulic Hand Dynamometer device among both healthy children and those diagnosed with pulmonary hypertension. Moreover, we compared the handgrip strength of pulmonary hypertension patients with significant prognostic indicators such as NYHA class, 6-minute walk test, and pro-brain natriuretic peptide.

RESULTS: The mean dominant handgrip strength was 20.8 ± 12 kg in the patient group and 21.6 ± 12.4 kg in the control group (p = 0.970). Handgrip strength was shown to be negatively connected with pro-brain natriuretic peptide (r = -0.565, p = 0.023) and positively correlated with 6-minute walk test (r = 0.586, p = 0.022) during the patient group evaluation.

CONCLUSION: Six-minute walk test needs a customised physical area (30 m of a straight hallway) and trained personnel for applying the test. The handgrip strength test, a different muscle strength indicator, can be used to more clearly and simply indicate the decline in patients’ ability for effort. Additionally, it was found in our study that handgrip strength decreased as pro-brain natriuretic peptide levels rose, a crucial measure in the monitoring of pulmonary hypertension.

ABSTRACT

INTRODUCTION: clinical practice guidelines recommend considering pharmacological treatment of obesity only as a complement to lifestyle modification. Drugs alone are usually ineffective in the long term after discontinuation, so pharmacological weight loss strategies should always be accompanied by lifestyle modifications.

OBJECTIVE: to analyze the changes in weight, body mass index and body composition by means of electrical bioimpedance after a 32-week treatment with liraglutide in patients with obesity, associated or not with a food education program.

MATERIALS AND METHODS: the study involved 68 patients who were randomly divided into 2 groups. One group received treatment with liraglutide 3.0 mg/day along with individual dietary education, and the other group was treated with liraglutide 3.0 mg/day and standard medical follow-up for 32 weeks. The data collected were weight (kg), height (m) (Seca® brand), body mass index (kg/m2) and body composition using multifrequency bioimpedance (SECA 112® brand). The variables were analyzed at the beginning and at the end of the treatment.

RESULTS: after 32 weeks of treatment, both study groups lost weight significantly. The group treated with liraglutide and individual dietary education had a reduction of 8.77 kg (9.08 %) (p < 0.001) and the group treated with liraglutide without education had a reduction of 3.55 kg (3.45 %) (p < 0.001). The BMI of the participants treated with liraglutide and education decreased by -4,04 kg/m2 (10.35 %) (p < 0.001) and in the group without education it decreased by -3.22 kg/m2 (8.30 %) (p = 0.003). In the educated group, fat mass decreased by -7.65 kg (15.89 %) (p < 0.001), although skeletal muscle mass also decreased by -1.62 kg (6.8 %) (p < 0.001). In those treated with liraglutide without education, a reduction in fat mass and skeletal muscle mass was also observed – fat mass by -4.72 kg (9.43 %) (p < 0.001) and skeletal muscle mass by -0.17 kg (0.70 %) (p < 0.001). Differences were also observed between groups, observing a greater reduction in weight, BMI, fat mass and skeletal muscle mass in the group with liraglutide and education compared to the group without education, although these differences were not statistically significant.

CONCLUSIONS: dietary education associated with liraglutide treatment may contribute to increasing weight loss and fat mass. However, it was also associated with an unwanted loss of skeletal muscle mass, probably related to the greater intensity of weight loss, which will have to be reversed in future therapeutic approaches. Habit modification through multidisciplinary treatment, including nutritional education, combined strength and resistance exercise, and cognitive-behavioral therapy, could be an effective way to treat obesity and maintain weight, body composition, and adherence to a lifestyle.

ABSTRACT

BACKGROUND: Packed red blood cell transfusions occur frequently after congenital heart surgery to augment haemodynamics, with limited understanding of efficacy. The goal of this study was to analyse the hemodynamic response to packed red blood cell transfusions in a single cohort, as “proof-of-concept” utilising high-frequency data capture of real-time telemetry monitoring.

METHODS: Retrospective review of patients after the arterial switch operation receiving packed red blood cell transfusions from 15 July 2020 to 15 July 2021. Hemodynamic parameters were collected from a high-frequency data capture system (Sickbay^TM) continuously recording vital signs from bedside monitors and analysed in 5-minute intervals up to 6 hours before, 4 hours during, and 6 hours after packed red blood cell transfusions-up to 57,600 vital signs per packed red blood cell transfusions. Variables related to oxygen balance included blood gas co-oximetry, lactate levels, near-infrared spectroscopy, and ventilator settings. Analgesic, sedative, and vasoactive infusions were also collected.

RESULTS: Six patients, at 8.5[IQR:5-22] days old and weighing 3.1[IQR:2.8-3.2]kg, received transfusions following the arterial switch operation. There were 10 packed red blood cell transfusions administered with a median dose of 10[IQR:10-15]mL/kg over 169[IQR:110-190]min; at median post-operative hour 36[IQR:10-40]. Significant increases in systolic and mean arterial blood pressures by 5-12.5% at 3 hours after packed red blood cell transfusions were observed, while renal near-infrared spectroscopy increased by 6.2% post-transfusion. No significant changes in ventilation, vasoactive support, or laboratory values related to oxygen balance were observed.

CONCLUSIONS: Packed red blood cell transfusions given after the arterial switch operation increased arterial blood pressure by 5-12.5% for 3 hours and renal near-infrared spectroscopy by 6.2%. High-frequency data capture systems can be leveraged to provide novel insights into the hemodynamic response to commonly used therapies such as packed red blood cell transfusions after paediatric cardiac surgery.
