ABSTRACT

BACKGROUND: Self-perceived oral health has been extensively investigated, but studies on homeless people are scarce, and there is currently no evidence from Latin America.

OBJECTIVE: To investigate the prevalence and factors associated with satisfaction with the oral health of homeless individuals in one Brazilian capital of the Midwest region.

SUBJECT AND METHODS: A cross-sectional study was carried out with 351 adult individuals attending a temporary public shelter who were interviewed about sociodemographic and psychosocial aspects, drugs use and oral health. The outcome was satisfaction with oral health (satisfied/dissatisfied). Pearson’s Chi-square test and Poisson regression with robust variance were used for statistical analysis.

RESULTS: The prevalence of dissatisfaction with oral health was 68.9% (95%CI= 63.9-73.6). After adjusting for covariates, dissatisfaction was more frequent among individuals who were married/in a stable relationship (PR= 1.18; 95%CI= 1.02-1.36), with felt need for treatment (PR= 2.27; 95%CI= 1.23-4.17) or complete prosthesis (PR= 1.35; 95%CI= 1.18-1.55); and those who used illicit drugs in the past six months (PR= 1.22; 95%CI = 1.06-1.39).

CONCLUSION: The prevalence of dissatisfaction with oral health in the homeless individuals studied was high and associated with their marital status, use of illicit drugs and self-reported need for dental treatment and complete prosthesis.

ABSTRACT

BACKGROUND: Recent studies have utilized MRI to determine the extent to which COVID-19 survivors may experience cardiac sequels after recovery.

PURPOSE: To systematically review the main cardiac MRI findings in COVID-19 adult survivors.

STUDY TYPE: Systematic review.

SUBJECTS: A total of 2954 COVID-19 adult survivors from 16 studies.

FIELD STRENGTH/SEQUENCE: Late gadolinium enhancement (LGE), parametric mapping (T1-native, T2, T1-post (extracellular volume fraction [ECV]), T2-weighted sequences (myocardium/pericardium), at 1.5 T and 3 T.

ASSESSMENT: A systematic search was performed on PubMed, Embase, and Google scholar databases using Boolean operators and the relevant key terms covering COVID-19, cardiac injury, CMR, and follow-up. MRI data, including (if available) T1, T2, extra cellular volume, presence of myocardial or pericardial late gadolinium enhancement (LGE) and left and right ventricular ejection fraction were extracted.

STATISTICAL TESTS: The main results of the included studies are summarized. No additional statistical analysis was performed.

RESULTS: Of 1601 articles retrieved from the initial search, 12 cohorts and 10 case series met our eligibility criteria. The rate of raised T1 in COVID-19 adult survivors varied across studies from 0% to 73%. Raised T2 was detected in none of patients in 4 out of 15 studies, and in the remaining studies, its rate ranged from 2% to 60%. In most studies, LGE (myocardial or pericardial) was observed in COVID-19 survivors, the rate ranging from 4% to 100%. Myocardial LGE mainly had nonischemic patterns. None of the cohort studies observed myocardial LGE in “healthy” controls. Most studies found that patients who recovered from COVID-19 had a significantly greater T1 and T2 compared to participants in the corresponding control group.

DATA CONCLUSION: Findings of MRI studies suggest the presence of myocardial and pericardial involvement in a notable number of patients recovered from COVID-19.

ABSTRACT

BACKGROUND: Delayed diagnosis of cerebrovascular disease (CVD) among patients can result in substantial harm. If diagnostic process failures can be identified at Emergency Department (ED) visits that precede CVD hospitalization, interventions to improve diagnostic accuracy can be developed.

METHODS: We conducted a nested case-control study using a cohort of adult ED patients discharged from a single medical center with a benign headache diagnosis from 10/1/2015-3/31/2018. Hospitalizations for CVD within 1 year of index ED visit were identified using a regional health information exchange. Patients with subsequent CVD hospitalization (cases) were individually matched to patients without subsequent hospitalization (controls) using patient’s age and visit date. Demographic, clinical, and ED processes characteristics were assessed via detailed chart review. McNemar’s test for categorical and paired t-test for continuous variables were used with statistical significance set at ≤0.05.

RESULTS: Of the 9,157 patients with ED headache visits, 57 (0.6%; 95% CI:0.5-0.8) had a subsequent CVD hospitalization. Median time from ED visit to hospitalization was 107 days. In twenty-five patients (43.9%; 25/57) the CVD hospitalization and the index ED visit were at different hospitals. Fifty-three cases and 53 matched controls were included in the final study analysis. Cases and controls had similar baseline demographic and headache characteristics. Cases more often had a history of stroke (32.1% vs. 13.2%, p=0.02) and neurosurgery (13.2% vs. 1.9%, p=0.03) prior to the index ED visit. Cases more often had <2 components of the neurological exam documented (30.2% vs. 11.3%, p=0.03).

CONCLUSION: We found that 0.6% of patients with an ED headache visit had subsequent CVD hospitalization, often at another medical center. ED visits for headache complaints among patients with prior stroke or neurosurgical procedures may be important opportunities for CVD prevention. Documented neurological examinations were poorer among cases, which may represent an opportunity for ED process improvement.

ABSTRACT

INTRODUCTION: Dorsal root ganglion (DRG) stimulation is a form of neuromodulation used to treat neuropathic pain due to a myriad of etiologies. Though this relatively new therapy has been shown to be quite effective, complications associated with the implantation of this therapy have not been well documented.

OBJECTIVES: The primary objective of this study was to describe the device-related complications associated with DRG stimulator implantations.

MATERIALS AND METHODS: This was a single-center retrospective analysis of 31 patients who underwent full implantation of neuromodulation hardware marketed for DRG stimulation. The predefined endpoints included device-related complications associated with DRG implantations, such as hardware failure, explantation procedures, and revision surgery. Additional endpoints included percentage of patients receiving therapy and pain as measured using the visual analog scale (VAS) pain scale at initial, six-month, and 12-month follow-up after hardware implantation.

RESULTS: Thirty-one patients were included out of 42 patients trialed. Baseline VAS in patients was 7.7 (31 patients). At initial follow-up, six-month follow-up, and one-year follow-up, VAS scores were 4.7 (31 patients), 5.3 (20 patients), and 5.5 (13 patients), respectively. Paired t-test between preoperative VAS (mean 7.3) and one-year follow-up VAS (5.5) demonstrated statistical significance (p = 0.027). At initial, six-month, and one-year follow-up, 30/31 (97%), 19/24 (79%), and 18/23 (78%) patients were confirmed to be receiving DRG stimulation therapy after permanent implant. Of the 31 patients who were implanted with a permanent system, 8 (26%) were explanted and an additional 10 (29%) required revision surgery.

CONCLUSION: In this study, we examine the various device-related complications associated with DRG stimulation requiring repeat surgery. High rates of hardware failure, revision surgery, and explantation of stimulators illustrate the need for hardware optimization to improve patient outcomes.

ABSTRACT

BACKGROUND: MRI is the most effective diagnostic tool of osteonecrosis of the femoral head (ONFH), especially for early diagnosis, but its detection of subchondral or cortical fractures is less accurate than CT. Therefore, it is difficult to accurately stage ONFH in the peri-collapse period by MRI.

PURPOSE: To improve the accuracy of MR for distinguishing between Association Research Circulation Osseous (ARCO) stages 2 and 3A in ONFH.

STUDY TYPE: Retrospective.

SUBJECTS: One hundred and fifty five cases of ARCO stage 2/3A of ONFH underwent MR examinations, M/F = 72/83. CT was used as reference standard for collapse, which was decided by an orthopedist and a radiologist in consultation.

FIELD STRENGTH/SEQUENCE: 3 T/axial and coronal T₁ -weighted Turbo Spin Echo (T₁ W TSE) sequence, axial T₂ -weighted fat-saturated (T₂ W FS) TSE sequence, and coronal proton density-weighted imaging (PDWI)-FS-Dixon fat/water image.

ASSESSMENT: Five potential MR signs (the maximum width of the necrotic-viable interface, bone marrow edema (BME), irregular articular surface of the femoral head, T₂ heterogeneous high signal, and the absence of a necrotic-viable interface with the morphology of closed loop) were evaluated blindly by five radiologists independently and the total scores of different combinations of MR signs were calculated.

STATISTICAL TESTS: Mann-Whitney U test and Chi-square test were used to evaluate age, gender, and MR signs differences between the two groups. ROC curve was used to access the distinguishing value of MR signs. The consistency of the five radiologists was analyzed by intraclass correlation coefficient.

RESULTS: The area under the curve of the combined MR signs 2 for distinguishing between ARCO stages 2 and 3A was the greatest (0.967), sensitivity and specificity were 100.00% and 88.71% respectively, and greater than 1 was the threshold.

DATA CONCLUSION: Combined MR signs 2 has great values in distinguishing between ARCO stages 2 and 3A in ONFH, thus helping clinical therapy.

ABSTRACT

AIM: This study aimed to explore the level and influencing factors of fatigue in patients with rheumatoid arthritis.

METHODS: This cross-sectional study was conducted in 243 patients with rheumatoid arthritis from April 2016 to March 2017. The Bristol Rheumatoid Arthritis Fatigue Multi-Dimensional Questionnaire, Arthritis Self-Efficacy Scale-8, Visual Analogue Scale for pain, physical function subscale of Short Form 36-Item Health Survey, Hospital Anxiety and Depression Scale, Perceived Social Support Scale, Pittsburgh Sleep Quality Index and a self-designed demographic and disease-related information questionnaire were used to collect the data. Stepwise linear multiple regression was used to clarify the impact of statistically significant variables (P < 0.05) in the independent sample t test, one-way ANOVA and correlation analysis on the level of fatigue.

RESULTS: Stepwise linear multiple regression analyses showed that disease activity, self-efficacy, physical function, pain, depression, duration of morning stiffness and anxiety were major factors influencing fatigue in patients with rheumatoid arthritis, which explained 59.5% of the total variance.

CONCLUSION: Our study demonstrated a moderate level of fatigue in Chinese patients with rheumatoid arthritis. In clinical practice, nurses should explore individualized intervention programmes based on related predictors of fatigue to help patients relieve fatigue.

ABSTRACT

AIMS AND OBJECTIVES: This study aimed to investigate the effects of socioeconomic-, patient-, treatment-, condition- and health system-related factors on medication adherence in patients with chronic obstructive pulmonary disease (COPD).

BACKGROUND: Medication adherence is essential for the management of chronic diseases. The World Health Organization created a Multidimensional Adherence Model (MAM) and showed that medication adherence is affected by a combination of numerous factors.

DESIGN: A descriptive correlational study was conducted.

METHODS: A total of 114 patients with COPD were included. Data were collected on five dimensions based on the MAM framework. Medication adherence, self-efficacy and symptoms were evaluated using the Adherence to Refills and Medications Scale-7 (ARMS-7), COPD Self-Efficacy Scale (CSES) and COPD Assessment Test (CAT), respectively. The data were analysed using descriptive statistics, correlational statistics and structural equation modelling. The STROBE checklist was used.

RESULTS: The ARMS-7 scores were associated with the body mass index of patients (F = 4.245, p = .017), smoke pack-years (r = .277, p = .004) and the CSES total score (β = -0.249, p = .002) in patient-related factors. The ARMS-7 score was not associated with socio-economic and health system-related factors. The ARMS-7 score showed a significant correlation between COPD diagnosis duration (r = -.276, p = .003) and the total number of drugs (r = -.215, p = .022) in treatment-related factors. The ARMS-7 scores were associated with the number of comorbid illnesses of patients with COPD in condition-related factors (F = 3.533, p = .033).

CONCLUSION: This study showed that medication adherence in COPD was mostly affected by patient-, treatment- and condition-related factors.

RELEVANCE TO CLINICAL PRACTICE: Healthcare professionals should establish training and counselling programs to increase the medication adherence level of patients, particularly for patients who are newly diagnosed, require multiple drugs and have comorbid diseases or low self-efficacy.

ABSTRACT

This study evaluated the effect of different surface-treatment protocols on the repair bond strength of a bulk-fill resin composite. One-hundred and forty specimens (Filtek Bulk-fill) were created (5 mm diameter, 4 mm depth) and allocated to one of 14 groups according to surface treatment (no treatment, tribochemical silica coating, sandblasting with aluminum oxide), adhesive application (no adhesive, total-etch, self-etch), and type of repair resin (bulk-fill, universal resin) (n = 10 per group). Twenty specimens were selected for measuring the cohesive strengths of non-aged resin composites and used as reference. Other specimens were thermocycled. Shear bond-strength testing was performed. Data were analyzed using linear regression of bond strength as a function of the surface treatment, type of adhesive and whether or not adhesive was applied, and type of repair resin. The failure modes were analyzed using logistic regression of failure mode (cohesive failure vs. other types, or adhesive failure vs. other types) on the type of surface treatment, adhesive application, and repair resin used. Surface treatment, regardless of whether this was tribochemical silica coating (mean difference = 5.44 MPa; 95% CI = 4.77-6.11) or sandblasting with aluminum oxide (mean difference = 4.22 MPa; 95% CI = 3.55-4.88), resulted in higher shear bond strength than no treatment. Application of adhesive resulted in a substantial and statistically significant decrease of shear bond strength (by 8.77 MPa, for self-etch and by 7.26 MPa for total-etch) relative to no adhesive. Conversely, the type of repair resin did not influence the shear bond strength to any appreciable extent.

ABSTRACT

Clusterwise statistical inference is the most widely used technique for functional magnetic resonance imaging (fMRI) data analyses. Clusterwise statistical inference consists of two steps: (i) primary thresholding that excludes less significant voxels by a prespecified cut-off (eg, p<.001 ); and (ii) clusterwise thresholding that controls the familywise error rate caused by clusters consisting of false positive suprathreshold voxels. The selection of the primary threshold is critical because it determines both statistical power and false discovery rate (FDR). However, in most existing statistical packages, the primary threshold is selected based on prior knowledge (eg, p<.001 ) without taking into account the information in the data. In this article, we propose a data-driven approach to algorithmically select the optimal primary threshold based on an empirical Bayes framework. We evaluate the proposed model using extensive simulation studies and real fMRI data. In the simulation, we show that our method can effectively increase statistical power by 20% to over 100% while effectively controlling the FDR. We then investigate the brain response to the dose-effect of chlorpromazine in patients with schizophrenia by analyzing fMRI scans and generate consistent results.

ABSTRACT

BACKGROUND: Penile cancer surgery affects physical, psychological, and sexual well-being, but the patient- and treatment-related factors predisposing to worse health-related quality of life (HRQoL) have not been well characterized.

AIM: We report treatment-related HRQoL changes among penile cancer survivors compared to the general population and the specific deficits that have the most profound effect, and we identify patient-related factors that predispose to a worse perceived HRQoL.

METHODS: Patients (n = 107) who underwent operations for invasive penile cancer in two Finnish university hospitals from 2009 to 2019 were sent the Patient Reported Outcomes (PROs) questionnaire designed to measure HRQoL, self-esteem, overall sexual functioning, erections, and change in sexual function. We collected clinical information and socio-demographic characteristics, including age, partner status, children, vocational education, and employment status. Associations between patient- and treatment-related factors and HRQoL were analyzed using descriptive statistics and non-parametric tests. Linear regression models were used to compare the HRQoL differences between patients with penile cancer and the age-standardized average for the Finnish population.

OUTCOMES: A generic measure of HRQoL (15D), the Rosenberg Self-Esteem Scale, Overall Sexual Functioning Questionnaire, the Erection Hardness Score, and self-reported change in sexual functioning.

RESULTS: Low scores in overall sexual functioning, erectile function, and changes in sexual functioning were associated with a lower HRQoL. An association was found between HRQoL and age, educational level, employment status, and place of residence. The HRQoL had a negative correlation with age. Patients with a high educational level, who were employed, or who lived in urban areas reported higher HRQoL. The mean HRQoL of penile cancer survivors was significantly lower than the age-standardized average HRQoL of the Finnish population.

CLINICAL IMPLICATIONS: Enhanced support and counseling is needed among penile cancer patients to improve the HRQoL during survivorship.

STRENGTHS & LIMITATIONS: A nationwide sample with detailed information allowed comparisons of HRQoL between penile cancer patients and the general population. Due to cross-sectional nature of the study, the time between the surgery and the study intervention was heterogeneous, and this may have affected the results.

CONCLUSION: Penile cancer patients exhibit significant physical and psychological dysfunction, and the lack of sexual activity in general is what most compromises the QoL of penile cancer survivors.
