It is estimated that globally, millions of adolescents experience mental health problems, especially anxiety and depression. Adolescents with high perceptions of stress often encounter mental issues, have negative thoughts or are dissatisfied with daily life events. This study employed a quasi-experimental design with two groups and repeated measures to test an innovative nursing intervention, the Be Aware of Stress Smartphone Application. This application aims to increase positive thinking and reduce perceived stress among at-risk adolescents aged 13 to 16, and we sought to determine their satisfaction with its usability. The study was conducted with 44 junior high school students from an opportunity expansion high school in Eastern Thailand, who were randomly assigned to experimental and comparison groups (22 each). Data were collected between December 2023 and February 2024 using the General Information Questionnaire, Positive Thinking Test, Perceived Stress Questionnaire, and Satisfaction of Application Usability scale. The outcomes were measured at baseline, after completing the program at week 4, and at week 8 after using the application. The chi-square test and repeated measures analysis of variance were used to analyze the data. The results of this study have important implications for future research. They indicate a significant improvement in positive thinking and a reduction in perceived stress within the experimental group, compared to the comparison group, at weeks 4 and 8. Moreover, the experimental group reported high satisfaction with the application's usability. These findings suggest that the Be Aware of Stress application is beneficial for community nurses and others to prevent adolescent stress. The study also highlights the need for future research to enhance the application's functionality and compatibility with various phone operating systems to ensure widespread and effective use.

Background and Design: Hematological parameters have been used as laboratory markers to evaluate the systemic inflammation in several rheumatic disease. The aim of this study is to determine the difference of hematological parameters between the patients who have been just fulfilled the Behçet's disease (BD) criteria and patients with recurrent aphthous stomatitis (RAS). Materials and Methods: Twenty patients with newly diagnosed BD and 47 patients with RAS whose oral ulcerations appeared at least three times a year were enrolled in this cross-sectional study. Demographic and clinical characteristics of patients, complete blood count, C-reactive protein (CRP) and erythrocyte sedimentation rate were recorded. Results: Patients' characteristics including gender, age, duration, and frequency of oral aphthous ulcerations in both study groups were comparable (p>0.05). CRP was significantly higher in newly diagnosed BD group when compared to the RAS group (p=0.001). CRP value higher than 2.7 g/dL, mean platelet volume (MPV) value higher than 7.58 fL and lymphocyte count higher than 2.85 103/μL were found to be the markers for distinguishing patients with BD from patients with RAS [odds ratio (OR): 12.76 (95% confidence interval (CI): 2.86-56.88), OR: 5.61 (95% CI: 1.11-28.42), OR: 15.24 (95% CI: 1.77-131.31), respectively]. Conclusion: The elevated CRP, MPV and lymphocyte count were associated with patients with newly diagnosed BD rather than patients with RAS. Further large prospective studies with the healthy control group are needed to confirm these findings. [ABSTRACT FROM AUTHOR]

Background: Healthcare professionals appear to play a key role in shaping pregnant women's views and attitudes towards lifestyle issues, such as exercise. The aim of this study is to investigate the views and beliefs of Greek midwives and obstetricians regarding exercise during pregnancy. Methods: This is a cross-sectional study conducted during the period of January 2022–March 2023. For this study, 237 Greek midwives and obstetricians employed in healthcare settings in Attica, Greece completed an anonymous and self-report questionnaire. Four different/independent models of multivariate analyses of variance were conducted. Results: The vast majority of these healthcare professionals (88.6%) believed that exercise during pregnancy is generally beneficial. According to the multivariate analyses, healthcare professionals with postgraduate/doctoral studies were more likely to believe that (a) exercise is generally beneficial (p = 0.03), (b) pregnant women should be informed about it (p = 0.028), (c) informing pregnant women is necessary/useful (p = 0.023), and (d) pregnant women showed interest in it (p = 0.034). Also, freelance midwives were more likely to believe that pregnant women should be informed about exercise (p = 0.006), and that they showed interest in it (p = 0.034). In addition, (a) freelance midwives (p = 0.050), and those who had experience in antenatal counselling (p = 0.037), as well as (b) obstetricians who were largely experienced in monitoring normal pregnancies (p = 0.001), were less likely to associate exercise during pregnancy with the occurrence of placental abruption. Conclusion: Alongside healthcare professionals' educational level, their professional setting and professional experience emerge as key factors and need to be considered when designing innovative interventions to support exercise during pregnancy.

The Omicron variants BA.1, BA.2, and BA.5 caused several waves of SARS-CoV-2 in Germany in 2022. In this comparative study, public health data on SARS-CoV-2 infections from Mecklenburg-Western Pomerania, Germany, between January and October 2022 were examined retrospectively using Pearson's chi-squared tests and Fisher's exact tests for testing for statistical significance. Compared to BA.5 infections, BA.1 and BA.2 infections affected younger individuals aged up to 19 years significantly more often, whereas BA.5 infections occurred significantly more frequently in patients between 40 and 59 years of age when compared to BA.1 and BA.2. Infections with all three variants predominantly caused flu-like symptoms; nevertheless, there were significant differences between the reported symptoms of BA.1, BA.2, and BA.5 infections. Especially, the symptoms of 'fever', 'severe feeling of sickness', 'loss of taste', and 'loss of smell' were significantly more often present in patients with BA.5 infections compared to BA.1 and BA.2 cases. Additionally, BA.2 and BA.5 cases reported significantly more often the symptoms of 'runny nose' and 'cough' than BA.1-infected cases. Our findings indicate remarkable differences in the clinical presentations among the sub-lineages, especially in BA.5 infections. Furthermore, the study demonstrates a powerful tool to link epidemiological data with genetic data in order to investigate their potential impact on public health. [ABSTRACT FROM AUTHOR]

Background and Aims: There is limited research on the impact of COVID-19 pandemic on caregivers of patients with severe mental illness (SMI) during its late phase when sufficient and widespread knowledge about management and preventive aspects existed. We aimed to assess the impact of COVID-19 pandemic on caregivers of patients with SMI during Omicron wave. Methodology: We assessed 100 caregivers of patients with preexisting SMI diagnosed on the Diagnostic and Statistical Manual of Mental Disorders-5, 50 each of schizophrenia and related psychotic disorders (SCZ) and bipolar disorder (BD) from December 14, 2021, to February 9, 2022. We assessed symptoms of depression, anxiety, stress, and family burden in caregivers and their coping strategies by the Depression, Anxiety, and Stress Scale-21 Hindi version, Family Burden Interview Schedule (FBIS), and Brief-Coping Orientation to Problem Experienced, respectively. Results: Caregivers of SMI experienced symptoms of depression (51%), anxiety (72%), and stress (13%), with significantly more symptoms of depression (P = 0.002) and anxiety (P = 0.025) in caregivers of SCZ. High caregiver burden (score: 25.76, > half of the total score on FBIS) was found with no significant difference in the two groups. Caregivers of SCZ used a greater number of emotion-focused coping strategies, whereas those with BD used more problem-focused coping, but the difference was not significant. A significant association was seen between coping strategies of substance use and depressed symptoms (P = 0.003), substance use and anxiety symptoms (P = 0.007); anxiety symptoms with denial (P = 0.001) anxiety symptoms and venting (P = 0.008) in caregivers of BD. Conclusion: Caregivers of patients with preexisting SMI experienced depression, anxiety, and high family burden during Omicron wave. They used both emotion- and problem-focused coping strategies.

The meaning of randomization tests has become obscure in statistics education and practice over the last century. This article makes a fresh attempt at rectifying this core concept of statistics. A new term—"quasi-randomization test"—is introduced to define significance tests based on theoretical models and distinguish these tests from the "randomization tests" based on the physical act of randomization. The practical importance of this distinction is illustrated through a real stepped-wedge cluster-randomized trial. Building on the recent literature on randomization inference, a general framework of conditional randomization tests is developed and some practical methods to construct conditioning events are given. The proposed terminology and framework are then applied to understand several widely used (quasi-)randomization tests, including Fisher's exact test, permutation tests for treatment effect, quasi-randomization tests for independence and conditional independence, adaptive randomization, and conformal prediction. for this article are available online.

Background: During transvenous lead extraction (TLE), a GlideLight laser sheath (Philips) cannot always be advanced over the lead, and crossover to the Evolution system (i.e., an Evolution RL sheath or Evolution Shortie RL sheath [Cook Medical]) is required. We aimed to determine the associated factors and outcomes of such device crossover. Methods: This observational study included 112 patients who underwent TLE. The patients were divided into crossover and non‐crossover groups. Outcomes and associated factors of crossover were evaluated. Results: Overall, 57 (50.9%) patients required crossover to the Evolution system (crossover group), whereas 55 (49.1%) patients did not require crossover (non‐crossover group). Clinical success rate was similar between the two groups (98.3% vs. 100%; p = 1.00). No major intraprocedural complications related to powered sheaths occurred. Multivariate logistic regression analysis results showed that dwell time of the oldest extracted lead (per year) (odds ratio [OR]: 1.18, 95% confidence interval [CI]: 1.02–1.36; p =.026), number of leads extracted per procedure (OR: 7.23, 95% CI: 1.74–29.99; p =.007), and use of a femoral approach (OR: 21.09, 95% CI: 2.33–190.67; p =.007) were associated factors of crossover. The cutoff for crossover was 7.7 years from the implant (sensitivity 90.5%, specificity 64.9%, area under the curve 0.80). Conclusions: Both groups showed a high rate of clinical success. Switching to the Evolution system may facilitate a safe and effective TLE when a laser sheath does not advance despite laser activation. [ABSTRACT FROM AUTHOR]

Second-hand smoke (SHS) has adverse effects for pregnant women and foetuses. This controlled and randomized clinical trial evaluated the efficacy of a comic booklet intervention in promoting SHS avoidance among pregnant women and appropriate smoking behaviours among their male partners. We allocated 140 couples to the experimental group (EG), who received the comic booklet and a reminder sticker, and 146 couples to the control group (CG), who received usual care. The primary outcomes were women's self-reported SHS exposure and their male partners' smoking behaviours. Secondary outcomes included knowledge and awareness of SHS. Independent t-tests revealed that three months post-intervention, more male partners in the EG had appropriate self-reported smoking behaviours with a small effect size (Cohen's d = 0.35, 95% CI [0.08, 0.62], p-value = 0.01). Significantly more pregnant women in the EG recognised their partners' appropriate smoking behaviours with a nearly middle effect size (Cohen's d = 0.43, 95% CI [0.16, 0.70], p-value ≤ 0.01). Cues to action showed a significant difference between groups with a small effect size (Cohen's d = 0.36, 95% CI [0.09, 0.63], p-value = 0.01), as evaluated by male partners. These findings suggest that the comic booklet intervention might be effective against SHS exposure by providing several cues to action through knowledge and awareness of SHS. [ABSTRACT FROM AUTHOR]

Background: Postoperative hypocalcemia in laryngectomy patients can occur when part or whole of the thyroid gland has been removed. Preservation of the parathyroid glands in situ is considered one of the initial measures to prevent postoperative hypocalcemia even if all thyroid gland is removed. Our study aims to assess the efficacy of parathyroid gland preservation in situ to prevent postoperative hypocalcemia in cases where total laryngectomy is done with total thyroidectomy. Methods: The study included all laryngectomy patients done during a period from April 2020 to May 2021. Parathyroid gland preservation was done in both primary (12 cases) and salvage (16 cases). Both PTH and corrected calcium level were measured at different time points and used as a guide for further replacement. Results: We studied the association between outcome including recovery from transient hypocalcemia and certain variables like age, type of surgery, stage of tumor, and extent of neck dissection. Regarding type of surgery, all patients that underwent primary laryngectomy were totally recovered (n = 12, 100%); however, salvage cases were partially recovered (n = 10, 62.5%). Conclusion: Parathyroid preservation is achievable in cases of salvage laryngectomy in addition to primary laryngectomy with total thyroidectomy. Early monitoring of the patients PTH and Ca during their hospital stay is a good indicator of successful preservation. Long-term follow-up is advised for potential recovery from transient hypoparathyroidism. [ABSTRACT FROM AUTHOR]

Existing research concerning the effects of the sitting birth position during the second stage of labour on maternal and neonatal outcomes remains controversial, and there is a lack of studies to explore its effect on the childbirth experience. The objective of this study is to explore whether the sitting birth position would influence maternal and neonatal outcomes, as well as the childbirth experience. The prospective cohort design was conducted in the study from February to June 2023, a total of 222 women (including primiparous women and multiparous women) were enrolled in our study, and they were divided into the sitting position cohort (n = 106) or the lithotomy position cohort (n = 116). The pre-designed questionnaire and Childbirth Experience Questionnaire (CEQ) were used for data collection during hospitalisation. Chi-square, Fisher's exact test, t-tests, or the Mann–Whitney U test were utilised to assess differences between groups. Multivariate linear regression and logistic regression were employed to control possible confounders. The study found that primiparous women in the sitting position cohort had a shorter duration of the second stage of labour, higher spontaneous vaginal birth rates, lower episiotomy rates, and a better childbirth experience (p < 0.01). After adjusting for confounding factors through multiple linear and logistic regression analyses, the results remained consistent with those reported above. No neonate in each cohort had Apgar scores at 1 min and 5 min postpartum less than 7 or a Cord artery pH less than 7.00, regardless of parity. Based on the findings, we recommend that women could take the sitting birth position into account when giving birth for a positive childbirth experience, especially for primiparous women. The study could also serve as a reference for healthcare providers in the management of childbirth positions and the development of high-quality maternal care. [ABSTRACT FROM AUTHOR]

In order to develop a statistical model for complex interactions among factors affecting early childhood caries development (ECC), 234 children from the "XXXX oral growth longitudinal study" were analysed at ages 3, 4 and 5. A questionnaire for children's parents (clinical history, nutritional and oral hygiene habits) and clinical oral examinations were recorded each year. The probabilistic dependence structure on the most significant factors was modelled with an Undirected Graphical Model (UGM or Markov random fields) which provides a probabilistic reasoning approach for the establishment of multi-way associations. The best fitting UGM was estimated through the maximum likelihood principle and two-way factor associations were verified through Fisher's exact statistical hypothesis tests for count data. The effect of sugar intake on caries incidence is mediated by oral hygiene; for caries incidence, oral hygiene quality is more relevant than toothbrushing time; the effect of pacifier on caries incidence is statistically significant only when considered in combination with breastfeeding time. Among behavioural ECC risk factors, the quality of oral hygiene, and not the toothbrushing frequency, is a primary factor that modulates the sugar intake in his primary role of the ECC developer. School-based oral health programs for ECC prevention should be improved with supervised toothbrushing program. UGM analysis could improve the school-based oral health programs with more effective and efficient prevention strategies based on the hierarchical interactions among the ECC risk factors. Oral hygiene plays a pivotal role in early childhood caries and can modulate positively or negatively their development. Supervised toothbrushing is a crucial intervention to be included in the daily educational and clinical practice and in the school-based oral health promotion programs. Trial registration: Clinical trial registration number: NCT02798809. [ABSTRACT FROM AUTHOR]

Background: Our aim was to determine whether child attachment to parents, parent attachment style, and morning cortisol levels were related to diabetes outcomes measured by average glycated hemoglobin (HbA1c), HbA1c variability over 4 years and time in range (TIR) in children with type 1 diabetes (T1D). Research design and methods: 101 children with T1D and one of their parents were assessed at baseline for child attachment (Child Attachment Interview; CAI) and parent attachment (Relationship Structures Questionnaire; ECR-RS). Serum samples were collected for cortisol measurements before the interviews. HbA1c levels were measured during a 4-year follow-up period at regular 3-monthly visits, and data for TIR were exported from blood glucose measuring devices. Multivariate linear regression models were constructed to identify independent predictors of glycemic outcomes. Results: More girls than boys exhibited secure attachment to their mothers. The results of the regression models showed that securely attached girls (CAI) had higher average HbA1c than did insecurely attached girls (B = −0.64, p = 0.03). In boys, the more insecure the parent's attachment style, the worse the child's glycemic outcome: the higher the average Hb1Ac (B = 0.51, p = 0.005), the higher the HbA1c variability (B = 0.017, p = 0.011), and the lower the TIR (B = −8.543, p = 0.002). Conclusions: Attachment in close relationships is associated with glycemic outcomes in children with T1D, and we observed significant differences between sexes. A sex- and attachment-specific approach is recommended when treating children with less favorable glycemic outcomes. Special attention and tailored support should be offered to securely attached girls in transferring responsibility for diabetes care and at least to male children of insecurely attached parents to prevent suboptimal glycemic control. Further studies in larger samples and more daily cortisol measurements may help us better understand the links between stress response, attachment and T1D. [ABSTRACT FROM AUTHOR]

Background: Preoperative interscalene brachial plexus block (ISB) has been shown to reduce postoperative nausea and vomiting after shoulder arthroscopy performed under general anesthesia (GA), possibly via reduced consumption of opioids. Postoperative urinary retention (POUR) is another adverse effect after GA with higher incidence among the elderly patients. The aim of this study is to investigate the effect of preoperative ISB on POUR. Methods: A historical cohort analysis of patients receiving shoulder arthroscopy under GA was conducted. Included patients were allocated to ISB+GA or GA only group. The difference in incidence of POUR between groups were explored as well as intraoperative requirement of inhaled anesthetics and fentanyl. Potential risk factors of POUR were also assessed with multivariate logistic regression analysis. Results: There are 229 patients in ISB+GA group and 169 patients in GA only group. Patient characteristics shows no difference between groups. ISB+GA group required lower concentration of inhaled anesthetics (fraction of minimum alveolar concentration (fMAC) 0.71 (0.16) vs. 0.93 (0.15), p < 0.001) and less total fentanyl dose (mcg kg-1, 1.9 (0.7) vs. 2.7 (1.1), p < 0.001). The incidence of POUR is lower in ISB+GA group than GA only group (3.9% vs. 10%, p = 0.02) as well as the incidence of postoperative nausea (28.4% vs. 39%, p = 0.03), and postoperative vomiting (16.2% vs. 25%, p = 0.03). Multivariate analysis reveals increased age and intraoperative fentanyl dose are associated with increased POUR. Conclusion: Preoperative ISB is associated with decreased consumption of intraoperative opioids, which may contribute to a reduced incidence of POUR. [ABSTRACT FROM AUTHOR]

Introduction: Fracture Liaison Services (FLS) has been proven effective in reducing subsequent fractures and related mortality. However, more research is needed on the impact of FLS on the 30-day readmission rate and its effectiveness in rural hospitals. This study aims to assess the impact of FLS on clinical outcomes including readmission rates, subsequent fractures, and fracture-related mortality in rural areas of an Asain country. Materials and methods: In a rural hospital in Taiwan, we conducted a two-year prospective cohort study on elderly individuals with fragility hip fractures. The study compared the clinical outcomes between the control group and the FLS-cohort group. Logistic regression analysis was used to identify factors contributing to 1-year mortality after injury. Results: 556 patients were enrolled. (304 in the control group and 252 in the FLS group) The mean age was 79.8 years. The findings revealed that the introduction of FLS did not result in significant differences in mortality, readmission, complication, subsequent fractures, or secondary hip fractures. However, there were notable improvements in the length of hospital stay and the proportion of patients receiving surgery within 48 h following the implementation of FLS. Subgroup analysis showed that FLS patients who received anti-osteoporotic treatment had lower mortality and 30-day readmission rates. Factors associated with higher 1-year mortality included male, high ASA level, and delayed surgery. Discussion: This study provides the real-life evidence of the effect of intensive FLS model in a rural hospital in an Asian country. Conclusion: While FLS did not show significant differences in certain clinical outcomes, it led to shorter hospital stays and increased timely surgeries. FLS patients receiving anti-osteoporotic treatment had better mortality and readmission rates. Further research is necessary to gain a comprehensive understanding of the impact of FLS care in rural areas of Asia. [ABSTRACT FROM AUTHOR]

Background: Prolonged symptoms of carpal tunnel syndrome (CTS) after primary carpal tunnel release (CTR) can reduce the quality of life and lead to multiple referrals across specialties. The following study aimed to identify differences in symptoms, signs, and intraoperative findings between recurrent and persistent CTS cases to avoid undesired outcomes after primary CTR. Methods: A retrospective analysis was conducted on revision CTRs performed between 2005 and 2015 using literature-based definitions for recurrent (a relapse of symptoms occurs following a symptom-free period of ≥3 months) and persistent (symptoms persisting longer than three months after surgical release) CTS. The parameters assessed were symptoms, clinical signs, and intraoperative findings. Results: Out of 53 cases, 85% (n = 45) were external referrals, whereby our own revision rate was 0.67% (n = 8/1199). Paresthesia and numbness were frequent in both groups; however, abnormal postoperative pain was reported more often in persistent cases (86%; n = 30/35) in comparison to recurrent cases (50%; n = 9/18; p = 0.009). Scarring around the median nerve was observed in almost all recurrent cases (94%; n = 17/18) and in 40% (n = 14/35) of persistent cases (p < 0.001). Incomplete division of the palmar ligament was the primary cause for revision in the persistent cohort (49%; n = 17/35). Conclusions: For patients experiencing symptoms for more than three months after CTR, primarily presenting as pain, it is advisable to consider referring the patient to a certified hand clinic for additional evaluation.

Objective: The risk of malignancy in pediatric thyroid nodules is higher compared to the risk in adults. Our aim was to investigate the clinical, radiological, and histopathological characteristics of pediatric thyroid nodules. Materials and Methods: The data of 132 children and adolescents who had thyroid nodules were collected retrospectively from medical records. Results: The mean age of the patients was 12.07 ± 4.08 years and 67% were female. Fine-needle aspiration biopsy was performed in 86 patients (65%) and the results were as follows: benign in 53.4% (n = 46), atypia or follicular lesion of undetermined significance in 3.5% (n = 3), suspicious for follicular neoplasia in 2.3% (n = 2), and malignancy in 32.5% (n = 28). The overall malignancy rate was 22.7% (n = 30). Malignancy was detected after surgery in 2 thyroid nodules belonging to the atypia or follicular lesion of undetermined significance category. Malignancy was detected in 7 patients who had autoimmune thyroiditis and in 1 patient who had congenital dyshormonogenesis. The malignancy rate of the nodules in the patients, who had autoimmune thyroiditis, was found to be 13.4%. Mixed echogenicity, microcalcifications, nodules larger than 10 mm, abnormal lymph nodes, and irregular borders were more common in the malignant group. The nodule size, abnormal lymph nodes, and irregular borders were found to be significant in terms of predicting malignancy. Conclusion: We found malignancy in 22.7% of the thyroid nodules, and the malignancy rate of nodules in the patients, who had autoimmune thyroiditis, was 13.4%. The nodule size, abnormal lymph nodes, and irregular nodule borders emerged as the most significant risk factors for malignancy. [ABSTRACT FROM AUTHOR]

Background: Preoperative anemia has been associated with perioperative morbidity and mortality in patients undergoing cardiac and non-cardiac surgery. Preoperative anemia is common in elderly hip fracture patients. The primary objective of the study was to explore the relationship between preoperative hemoglobin levels and postoperative major adverse cardiovascular events (MACEs) in hip fracture patients over 80 years. Methods: The retrospective study enrolled hip fracture patients over 80 years from January 2015 to December 2021 in our center. The data were collected from the hospital's electronic database after approval by the ethics committee. The primary objective of the study was to investigate MACEs, and the secondary objectives included in-hospital mortality, delirium, acute renal failure, ICU admission rate, and transfusion (>2 U). Results: 912 patients were entered for final analysis. Based on the restricted cubic spline, the risk of preoperative hemoglobin (<10 g/DL) was associated with an increased risk of postoperative complications. With univariable logistic analysis, a hemoglobin level <10 g/DL was associated with increased MACEs [OR 1.769, 95% CI (1.074, 2.914), P =.025], in-hospital mortality [OR 2.709, 95% CI (1.215, 6.039), P =.015] and transfusion >2 U risk [OR 2.049, 95% CI (1.56, 2.69), P <.001]. Even after adjustment for confounding factors, MACEs [OR 1.790, 95% CI (1.073, 2.985), P =.026], in-hospital mortality [OR 2.81, 95% CI (1.214, 6.514), P =.016] and transfusion >2 U rate [OR 2.002, 95% CI (1.516, 2.65), P <.001] were still higher in the lower hemoglobin level cohort. Moreover, a log-rank test showed increased in-hospital mortality in the cohort with a preoperative hemoglobin level of <10 g/DL. However, there was no difference in delirium, acute renal failure, and ICU admission rates. Conclusions: In conclusion, for hip fracture patients over 80 years, preoperative hemoglobin levels <10 g/DL might be associated with increased postoperative MACEs, in-hospital mortality, and transfusion >2 U.

OBJECTIVES: Incidental small renal masses (SRMs) now account for the majority of new diagnoses of renal cancers. Although there are established management guidelines, referral and management patterns can vary. We aimed to explore identification, practice patterns, and management of identified SRMs in an integrated health system. STUDY DESIGN: Retrospective analysis. METHODS: We identified patients with a newly diagnosed SRM measuring 3 cm or less from January 1, 2013, to December 31, 2017, at Kaiser Permanente Southern California. These patients were flagged at the time of radiographic identification to ensure adequate notification of findings. Diagnostic modality, referral, and treatment patterns were analyzed. RESULTS: Of 519 patients with SRMs, 65% were found on abdominal CT and 22% on renal/abdominal ultrasounds. Within 6 months, 70% of patients consulted with a urologist. Initial management patterns were as follows: active surveillance (60%), partial/radical nephrectomy (18%), and ablation (4%). Among 312 patients on surveillance, 14% eventually received treatment. The majority of patients (69.4%) did not receive guideline-recommended chest imaging for initial staging. Urologist visit within 6 months of SRM diagnosis was associated with increased adherence to staging (P = .003) and subsequent surveillance imaging (P < .001). CONCLUSIONS: In this contemporary analysis of an integrated health system's experience, referral to a urologist was associated with guideline-concordant staging and surveillance imaging. Frequent utilization of active surveillance with a low rate of progression to active treatment was noted in both groups. These findings shed light on care patterns upstream of urologic evaluation and support the need for clinical pathways to be implemented at the time of radiologic diagnosis. [ABSTRACT FROM AUTHOR]

Background: Previous research has documented the proportion of "tall and fall" (TF) and "drop and drive" (DD) pitching styles among Major League Baseball (MLB) pitchers who underwent ulnar collateral ligament reconstruction (UCLR). The proportion of these 2 styles among all MLB pitchers remains unknown. Purpose: To determine the proportion of the TF and DD pitching styles in all rostered MLB pitchers during a single season as well as the proportion of TF and DD pitchers who sustained an upper extremity (UE) injury and those who underwent UCLR. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Pitcher demographic characteristics from the 2019 MLB season and pitching information were obtained via open-access sources. Two-dimensional video analysis was used to categorize the included pitchers into TF and DD groups. Statistical comparisons and contrasts were made using 2-tailed t tests, chi-square tests, and Pearson correlation analyses as appropriate. Results: Of the 660 MLB rostered pitchers in 2019 (age, 27.39 ± 3.51 years; body mass index, 26.34 ± 2.47 kg/m2; fastball velocity, 150.49 ± 3.99 kph [93.51 ± 2.48 mph]), 412 (62.4%) pitchers used the TF style and 248 (37.6%) pitchers used the DD style. Significantly more UE injuries were seen in the TF group compared with the DD group (112 vs 38 injuries, respectively; P <.001). Twelve pitchers underwent UCLR (TF, 10; DD, 2), representing a 1.8% UCLR rate among all pitchers. This was a second surgery for 2 pitchers, both of whom used the TF pitching style. Significantly more pitchers in the TF group than the DD group had undergone UCLR before 2019 (135 vs 56 pitchers, respectively; P =.005). Conclusion: The results of the present study demonstrated a higher prevalence of both UE injury and prior UCLR in TF pitchers. Further research is needed to explore the potential association between pitching style and UE injury. [ABSTRACT FROM AUTHOR]

Shear wave elastography (SWE) is a non-invasive imaging technique used to quantify the elasticity/stiffness of any tissue. There are normative SWE studies on tonsils in healthy children in the literature. The purpose of this study is to analyze the palatine tonsils in children with acute tonsillitis using ultrasound and SWE. In this prospective study, pediatric patients aged 4–18 years diagnosed with acute tonsillitis and healthy children were included. Those with antibiotic use, chronic tonsillitis, adenoid hypertrophy, and having chronic disease, immunodeficiency, and autoimmune disease, or any rheumatological disease were excluded. The volume and elasticity of palatine tonsil were measured via ultrasound and SWE. The study included 81 (46 female, 35 male) acute tonsillitis patients, and 63 (38 female, 25 male) healthy children between the ages of 4 and 18. Elasticity (kPa) values of tonsils were found significantly higher in the tonsillitis group (SWE-R: 25.39 ± 4.64, SWE-L: 25.01 ± 4.17) compared to the normal group (SWE-R: 9.71 ± 2.37, SWE-L: 9.39 ± 2.19) (p < 0.001). In the tonsillitis group, a significant positive correlation was found between tonsil volume and elasticity (r: 0.774, p: 0.002). In conclusion, in pediatric patients with acute tonsillitis, higher kPa values were obtained with SWE in the palatine tonsils. [ABSTRACT FROM AUTHOR]

Background: To investigate venous thromboembolism (VTE) in hospitalized patients with severe high altitude pulmonary edema (HAPE), we performed a single center retrospective study to evaluate its clinical characteristics, prognosis, and potential thromboprophylaxis strategies in a large referral and treatment center in plateau regions. Methods: We studied a total of 18 patients with severe HAPE from January 1, 2012 to December 31, 2021. Demographic and clinical data, laboratory data, including ultrasound scans of the lower extremities and cardiac ultrasound, and computed tomographic pulmonary angiography (CTPA) variables were obtained, and comparisons were made between groups with and without VTE. Results: Of the 18 patients hospitalized with severe HAPE (age 43 (range, 34–54) years, 14 [77.8%] men), 7 patients developed VTE (38.9%), including 5 with deep vein thrombosis (DVT) and pulmonary embolism (PE), 2 of whom had DVT only. Eighteen patients are all firstly rapid ascent to high altitudes which the mean altitude was 3700 m (3656–4050 m). Compared with patients who did not have VTE, patients with VTE had a longer time in hospital (13 [11, 19] versus 9 [7, 12]; P = 0.027), respiratory failure (6 [85.7%] versus 2 [18.2%]; P = 0.013), the shortened APTT (21.50 [19.00, 27.50] versus 26.30 [24.80, 30.10]; P = 0.044) and the higher level of D-dimer (7.81 [4.62, 9.60] versus 2.90 [1.75, 3.37]; P = 0.003). The proportion of thromboprophylaxis is too low in our cohort which 2 of 18 (11.1%) patients were given VTE prophylaxis. There was no statistically significant difference between the VTE and non-VTE groups (0 [0.0%] versus 2 [18.2%]; P = 0.497). Conclusions: The prevalence of VTE is high in hospitalized patients with severe high altitude pulmonary edema (HAPE). Prophylaxis for venous thromboembolism may be protective in severe HAPE patients after admission. Our data seem to suggest that VTE is probably an additional prognostic factors in patients with severe HAPE. [ABSTRACT FROM AUTHOR]

Objective: to investigate the factors associated with extubation failure of patients in the intensive care unit. Method: unpaired, longitudinal, retrospective and quantitative case-control with the participation of 480 patients through clinical parameters for ventilator weaning. Data were analyzed by: Fisher's exact test or the chi-square test; unpaired two-tailed Student's t test; and Mann-Whitney test. Significant P values lower than or equal to 0.05 were admitted. Results: of the patients, 415 (86.5%) were successful and 65 (13.5%) failed. Success group: the most negative fluid balance, APACHE II in 20 (14-25), weak cough in 58 (13.9%). Failure group: the most positive fluid balance, APACHE II in 23 (19-29), weak cough in 31 (47.7%), abundant amount of pulmonary secretions in 47.7%. Conclusion: positive fluid balance and the presence of inefficient cough or inability to clear the airway were predictors of extubation failure. [ABSTRACT FROM AUTHOR]

Objective: to analyze the profile of nurses regarding integrative and complementary practices in health (ICPH) and understand how they are used in the care of people with arterial hypertension. Method: mixed-methods sequential explanatory design. The cross-sectional quantitative stage included 386 nurses who completed an online questionnaire addressing sociodemographic and professional information, training, and practice, with a descriptive and inferential analysis. The qualitative stage was performed via 18 online interviews with professionals who had ICPH training and implemented it in the care provided to individuals with hypertension, with a participatory analysis. Integration occurred through a connecting approach. Results: 36.8% had ICPH training; most were women, Caucasian, married, public servants, aged 37 (+ 9.4) on average; 14.2% incorporated ICPH into the care provided to people with hypertension; predominantly auriculotherapy (28.2%) and bloodletting in hypertensive crises. The results show that nurses integrally approached patients, and their approach was not limited to the vital sign altered at the time, but they also intervened in anxiety, stress, sleep, and rest. A potentiality observed concerns support treatment adherence. Conclusion: the profile of nurses with ICPH training is presented, and such practice has implications for lowering blood pressure. ICPH has been incorporated into the care of people with hypertension, but its use is still incipient, considering its potential in nursing care. [ABSTRACT FROM AUTHOR]

Background: This randomized clinical trial was conducted to assess whether sleep bruxism (SB) is associated with an increased rate of technical complications (ceramic defects) in lithium disilicate (LiDi) or zirconia (Z) molar single crowns (SCs). Methods: Adult patients were classified as affected or unaffected by SB based on structured questionnaires, clinical signs, and overnight portable electromyography (BruxOff) and block randomized into four groups according to SB status and crown material (LiDi or Z): LiDi-SB (n = 29), LiDi-no SB (n = 24), Z-SB (n = 23), and Z-no SB (n = 27). Differences in technical complications (main outcome) and survival and success rates (secondary outcomes) one year after crown cementation were assessed using Fisher's exact test with significance level α = 0.05. Results: No technical complications occurred. Restoration survival rates were 100% in the LiDi-SB and LiDi-no SB groups, 95.7% in the Z-SB group, and 96.3% in the Z-no SB group (p > 0.999). Success rates were 96.6% in the LiDi-SB group, 95.8% in the LiDi-no SB group (p > 0.999), 91.3% in the Z-SB group, and 96.3% in the Z-no SB group (p ≥ 0.588). Conclusions: With a limited observation time and sample size, no effect of SB on technical complication, survival, and success rates of molar LiDi and Z SCs was detected. [ABSTRACT FROM AUTHOR]

Introduction: This study aimed to investigate the incidence of rheumatoid arthritis (RA) flare-ups following immunization with the Sinopharm COVID-19 inactivated virus-based vaccine. Methods: We conducted a retrospective observational study at the Rheumatology Clinic of Imam Hossein Hospital, incorporating 200 RA patients in remission undergoing non-biologic Disease-Modifying Antirheumatic Drugs (DMARDs) treatments. A rheumatologist confirmed a flare-up based on patients complain of arthralgia and joint stiffness and complete examination of joints over a three-month period following vaccination. Results: Twelve percent of all included patients experienced symptom recurrence. The average age of patients with flare-ups was significantly higher, but no gender-based differences were observed (p<0.001 and p=0.071, respectively). The second vaccine dose resulted in a higher number of symptom flares compared to the first dose (9.30% vs. 3.0%, p < 0.001). No significant differences were observed between patients experiencing flare-ups after the first dose and the second dose in terms of the number of involved joints (p=0.321) and the time gap from vaccination to symptom recurrence (p=0.526). No patients required hospitalization, and prednisolone dosage adjustments effectively managed symptoms. Conclusion: The occurrence of flare-ups was relatively low after the Sinopharm COVID-19 vaccination in RA patients undergoing treatment with DMARDs during remission. The majority of these flares were mild and no hospitalizations were required. [ABSTRACT FROM AUTHOR]

Background: Preoperative anemia has been associated with perioperative morbidity and mortality in patients undergoing cardiac and non-cardiac surgery. Preoperative anemia is common in elderly hip fracture patients. The primary objective of the study was to explore the relationship between preoperative hemoglobin levels and postoperative major adverse cardiovascular events (MACEs) in hip fracture patients over 80 years. Methods: The retrospective study enrolled hip fracture patients over 80 years from January 2015 to December 2021 in our center. The data were collected from the hospital's electronic database after approval by the ethics committee. The primary objective of the study was to investigate MACEs, and the secondary objectives included in-hospital mortality, delirium, acute renal failure, ICU admission rate, and transfusion (>2 U). Results: 912 patients were entered for final analysis. Based on the restricted cubic spline, the risk of preoperative hemoglobin (<10 g/DL) was associated with an increased risk of postoperative complications. With univariable logistic analysis, a hemoglobin level <10 g/DL was associated with increased MACEs [OR 1.769, 95% CI (1.074, 2.914), P = .025], in-hospital mortality [OR 2.709, 95% CI (1.215, 6.039), P = .015] and transfusion >2 U risk [OR 2.049, 95% CI (1.56, 2.69), P < .001]. Even after adjustment for confounding factors, MACEs [OR 1.790, 95% CI (1.073, 2.985), P = .026], in-hospital mortality [OR 2.81, 95% CI (1.214, 6.514), P = .016] and transfusion >2 U rate [OR 2.002, 95% CI (1.516, 2.65), P < .001] were still higher in the lower hemoglobin level cohort. Moreover, a log-rank test showed increased in-hospital mortality in the cohort with a preoperative hemoglobin level of <10 g/DL. However, there was no difference in delirium, acute renal failure, and ICU admission rates. Conclusions: In conclusion, for hip fracture patients over 80 years, preoperative hemoglobin levels <10 g/DL might be associated with increased postoperative MACEs, in-hospital mortality, and transfusion >2 U.

Purpose: Heparin-based regimens are recommended for anticoagulation in hospitalized patients with COVID-19 though a study reported similar mortality with apixaban in critically ill hospitalized COVID-19 patients. Our pilot study sought to determine the differences in all-cause mortality, venous thromboembolism (VTE), and bleeding events between apixaban and therapeutic heparin-based regimens in hospitalized non-critically ill COVID-19 patients. Methods: We conducted a retrospective analysis of non-critically ill COVID-19 patients aged ≥ 18 years admitted to 3 campuses of Montefiore Medical Center during the first (March 2020 to May 2020) and second (January 2021 to February 2021) COVID-19 surges, who received within 48 hours of admission and continued for ≥72 hours a therapeutic dose of low-molecular-weight heparin (LMWH), unfractionated heparin (UFH), or any apixaban dose for VTE prophylaxis. Outcomes data analyzed included mortality, suspected or imaging-confirmed VTE, and bleeding using a defined criteria. Results: Overall, 162 patients met eligibility for analysis. Baseline characteristics were similar between the 2 groups except liver and renal functions. Mortality occurred in 10 (13.3%) patients on apixaban and 23 (26.4%) patients on a heparin-based regimen (P =.059). Confirmed VTE events were not different between the groups (8% vs 13.8%, P =.359), but higher incidence of bleeding occurred in heparin-based group (4% vs 52.9%, P <.001). Conclusion: There were no differences in mortality or confirmed VTE between apixaban and heparin-based regimens except for more bleeding events with the heparins. This study highlights the utility of apixaban in COVID-19. [ABSTRACT FROM AUTHOR]

Background: Data regarding the efficacy of the dental clearance required prior to kidney transplantation (KT) for preventing post-transplant complications is controversial. The aim of this retrospective study was to investigate a possible correlation between any untreated oral infectious foci and the onset of systemic complications in KT patients. Methods: Patients scheduled for regular check-ups during the post-transplant period were visited at the C.I.R. Dental School in Turin, Italy. Patients were asked to bring orthopantomography (OPT) acquired prior to transplantation to compare the possible presence of untreated infectious foci at the time of transplantation with the time of their post-transplant visit. Patients were then divided, according to the evaluation of the OPT obtained prior to the transplantation, into two groups according to their dental status prior to the transplant. "Group Infected" was comprised of patients with no dental clearance, and "Group Clear" included patients with dental clearance. The medical records were then retrospectively reviewed for the evaluation of any systemic complications that occurred after transplantation. The following medical complications were considered: fever, pneumonia, urinary tract infections, systemic infections, kidney rejection, and death. Complications were divided in two groups: early complications, which occurred within 100 days of transplantation, and late complications, which occurred more than 100 days after transplantation. Results: A total of 77 patients were enrolled in the study. Group Infected was composed of 19 subjects (25%), while Group Clear was composed of 58 patients (75%). In Group Infected, 13 (68%) patients developed complications within 100 days of transplantation, and 11 (58%) did so after 100 days. In Group Clear, 31 (53%) patients had complications within 100 days of the transplant, and 23 (40%) did after 100 days. Patients in Group Infected had a statistically significant increase in episodes of fever (p = 0.03), compared to Group Clear, with a higher relative risk (RR) of 3.66 in the first 100 days after transplantation. Conclusion: Within the limitations of the present retrospective pilot study, and based on the results, a correlation between the absence of dental clearance prior to KT and a higher RR of developing a fever within the first 100 days post transplantation was highlighted. The present results encourage doctors to continue research on the topic, which remains controversial. Further prospective studies are required to confirm the results of the present study.

Background: Adjuvant chemotherapy (ACT) is considered for high‐risk patients in stage IB lung adenocarcinoma (LUAD). However, these risk factors are recognized as negative prognostic factors, not as predictors of ACT efficacy. This study aimed to analyze the efficacy of ACT in stage IB patients by retrospectively examining patients who had recurrence. Methods: We reviewed 1399 patients with stage IB (American Joint Committee on Cancer 7th edition) LUAD from 2012 to 2017 in our institution and found 147 patients with recurrence. The last follow‐up date was December 30, 2021. One‐to‐one propensity‐score matching (PSM) was used to reduce the potential selection bias. Results: Fifty‐five (37.4%) patients had received ACT and 92 (62.6%) had not (non‐ACT). Patients with ACT were younger (p < 0.001), had larger tumors (p < 0.001) and more lymphovascular invasion (p = 0.02), and seemed to have less distant recurrence (p = 0.001). After PSM, 110 patients were matched and baseline characteristics were balanced. ACT was not associated with improved disease‐free survival (DFS) after matching (mDFS = 23.5 m for ACT vs. 29.5 m for non‐ACT, p = 0.13). ACT failed to prolong DFS of patients in the extracranial recurrence subgroup and EGFR mutation subgroups, and was even associated with shorter DFS in intracranial relapsed patients (mDFS = 30.3 m vs. 33.5 m, p = 0.083) and patients with tumor ≤30 mm (mDFS = 21.9 m vs. 30.8 m, p = 0.076). Conclusion: In patients who were destined to develop recurrence after completely resected stage IB LUAD, ACT might not be associated with improved DFS. Further large multicenter studies are warranted to validate these findings. [ABSTRACT FROM AUTHOR]

Background: Effective team leadership and good activation criteria can effectively initiate rapid response system (RRS) to reduce hospital mortality and improve quality of life. The first reaction time of nurses plays an important role in the rescue process. To construct a nurse-led (nurse-led RRS) and activation criteria and then to conduct a pragmatic evaluation of the nurse-led RRS. Methods: We used literature review and the Delphi method to construct a nurse-led RRS and activation criteria based on the theory of "rapid response system planning." Then, we conducted a quasi-experimental study to verify the nurse-led RRS. The control group patients were admitted from August to October 2020 and performed traditional rescue procedures. The intervention group patients were admitted from August to October 2021 and implemented nurse-led RRS. The primary outcome was success rate of rescue. Setting: Emergency department, Gansu Province, China. Results: The nurse-led RRS and activation criteria include 4 level 1 indicators, 14 level 2 indicators, and 88 level 3 indicators. There were 203 patients who met the inclusion criteria to verify the nurse-led RRS. The results showed that success rate of rescue in intervention group (86.55%) was significantly higher than that in control group (66.5%), the rate of cardiac arrest in intervention group (33.61%) was significantly lower than that in control group (72.62%), the effective rescue time of intervention group (46.98 ± 12.01 min) was shorter than that of control group (58.67 ± 13.73 min), and the difference was statistically significant (P < 0.05). The rate of unplanned ICU admissions in intervention group (42.85%) was lower than that in control group (44.04%), but the difference was not statistically significant (P > 0.05). Conclusions: The nurse-led RRS and activation criteria can improve the success rate of rescue, reduce the rate of cardiac arrest, shorten the effective time of rescue, effectively improve the rescue efficiency of patients.

Objective The prognostic markers of hepatocellular carcinoma (HCC) patients with bone metastasis are of great significance for the design of treatment strategy, the maintenance of life quality of the patients, and the improvement of cancer prognosis. MicroRNA-149 (miR-149) rs2292832 C/T polymorphism in HCC patients has been reported to be associated with the risk of HCC, but whether it can predict the prognosis of HCC patients with bone metastasis remains unclear. The goal of our study was to examine the prognostic impact of miR-149 rs2292832 C/T polymorphism on HCC patients with bone metastasis. Methods A total of 67 cases of HCC patients with bone metastasis (BC group) and 73 cases of HCC patients without bone metastasis (NC group) were included in this study. The miR-149 levels in blood leukocytes and tumor tissues were determined by qRT-PCR. Genotyping analysis of miR-149 rs2292832 was performed using polymerase chain reaction (PCR)-restriction fragment length polymorphism assay. Results The blood leukocyte miR-149 levels were significantly decreased in HCC patients, compared with the healthy controls, and they were significantly decreased in the BC patients, compared with the NC cases. BC patients carrying miR-149 rs2292832 CC+CT phenotype have a better overall survival (OS) rate, whereas no significant correlation was found between miR-149 rs2292832 CC+CT phenotype and the OS rate in NC group. The miR-149 rs2292832 CC+CT phenotype was correlated with certain bone turnover markers and bone metabolism markers but was not correlated with receptor activator of nuclear factor-kappaB ligand (RANKL) expression. Meanwhile, the combination of miR-149 rs2292832 CC+CT phenotype and RANKL expression could improve the prognosis assessment of HCC patients with bone metastasis. Conclusion miR-149 rs2292832 polymorphism might be a novel prognostic biomarker for HCC patients with bone metastasis. A follow-up study with a larger cohort from a multicenter should be performed to test our conclusions. [ABSTRACT FROM AUTHOR]

Background: A prompt and accurate diagnosis of developmental defects of enamel (DDE) is mandatory for proper treatment management. This cross-sectional survey, designed and carried out using anonymous self-administered questionnaires, aimed to assess dental and dental hygiene students' knowledge and their capability to identify different enamel development defects. Methods: The questionnaire consisted of twenty-eight closed-ended questions. Two different samples of undergraduate students were selected and enrolled: a group of dental hygiene (GDH) students and a group of dental (GD) students. A multivariate logistic regression was performed by adopting the correct answers as explanatory variables to assess the difference between the two groups. Results: Overall, 301 completed questionnaires were analyzed: 157 from the GDH and 144 from the GD. The dental student group showed better knowledge than the GDH of enamel hypomineralization and hypoplasia (p = 0.03 for both). A quarter (25.25%) of the total sample correctly identified the period of development of dental fluorosis with a statistically significant difference between the groups (p < 0.01). Amelogenesis imperfecta (AI) was identified as a genetic disease by 64.45% of the sample, with a better performance from the GD (p = 0.01), while no statistical differences were found between the groups regarding molar incisor hypomineralization. Multivariate analysis showed that AI (OR = 0.40, [0.23;0.69], p < 0.01) and caries lesion (OR = 0.58, [0.34;0.94], p = 0.03) were better recognized by the GD. Conclusions: Disparities exist in the knowledge and management of DDE among dental and dental hygiene students in Italy; however, significant knowledge gaps were found in both groups. Education on the diagnosis and treatment of DDE during the training for dental and dental hygiene students needs to be strongly implemented. [ABSTRACT FROM AUTHOR]

Introduction: Randomised clinical trials (RCTs) report similar outcomes following neoadjuvant (NAC) and adjuvant chemotherapy (AC) in breast cancer. "Fragility Indices" (FI) test significance reversal reported in RCTs. Aim: To evaluate the FI of findings from RCTs assessing outcomes of NAC and AC. Methods: A systematic review was performed as per PRISMA guidelines. RCTs of interest were identified and data pooled. Fisher's exact test was used to calculate FI for reversal of statistical significance for dichotomous outcomes. "Fragility Quotient" (FQ) was calculated by division of the calculated FI by the sample size. Results: Ten RCTs including 4928 patients. Mean follow-up was 8.2 years. For breast conservation surgery (BCS), the FI was 500 and FQ was 0.10781. For local recurrence (LR), the FI was 42 and FQ was 0.00852. FI and FQ varied for LR at 0– 4 years (FI: 9), 5– 9 years (FI: 2), 10– 14 years (FI: 4), and 15+ years (FI: 3). Regarding distant recurrence (DR), the FI was 13 and FQ was 0.00264. FI and FQ trended downwards over time: 0– 4 years (FI: 56), 5– 9 years (FI: 18), 10– 14 years (FI: 4), and 15+ years (FI: 4). For breast-cancer-specific mortality (BCSM), the overall FI was 51 and FQ was 0.01035. FI and FQ varied for BCSM at 0– 4 years (FI: 5), 5– 9 years (FI: 19), 10– 14 years (FI: 8), and 15+ years (FI: 5). For overall survival (OS), the FI was 17 and FQ was 0.00345. FI and FQ were calculated with respect to OS at 0– 4 years (FI: 19), 5– 9 years (FI: 17), 10– 14 years (FI: 19), and 15+ years (FI: 1). Conclusion: FIs comparing survival following NAC and AC were of moderate-to-high fragility, indicating weak statistical significance. BCS eligibility following NAC was of low fragility, ratifying the oncological and surgical safety of NAC versus AC. Level of Evidence: Systematic Review of Level I Randomised Control Trials.

Background: Cardiac Implantable Electronic Devices (CIED) include pulse generators and leads. In some implanting centers, it is a common practice to combine devices with leads from different companies. Case series have reported episodic high‐impedance changes in Boston Scientific CIEDs with competitor leads. We investigated the incidence of high‐impedance abnormalities in matched versus mismatched Boston Scientific Accolade pacemakers. Methods: A retrospective chart review identified all consecutive Boston Scientific Accolade pacemakers implanted between January 2017 and June 2019 at a Canadian tertiary care center. The primary outcome was the occurrence of transient, high‐impedance changes which resulted in a switch to unipolar pacing/sensing in the absence of any other identifiable lead issue. Fisher exact tests (two‐tailed, α =.05) were used to compare the incidence of outcomes in matched versus mismatched systems. Results: 514 Boston Scientific Accolade pacemakers were associated with 882 individual leads. The primary outcome occurred with 21 leads (20 Medtronic and 1 Abbott), associated with occasional pacing inhibition, presyncope, and/or early surgical revision. Mismatched lead‐device pairs were significantly associated with CIED malfunction compared to matched lead‐device pairs (3.3% vs. 0%, p =.0019). The median time from implant to unipolar safety switch was 12.4 months. The median follow‐up time was 21.6 months. Conclusion: Use of mismatched leads with a Boston Scientific Accolade device was associated with an increased risk of undesirable changes in sensing polarity with occasional inappropriate pacing inhibition. Awareness of this interaction can allow for the institution of appropriate programming remedies and may increase scrutiny of the use of mismatched CIED systems. [ABSTRACT FROM AUTHOR]

BACKGROUND Uninterrupted use of oral anticoagulants before atrial fibrillation (AF) ablation can reduce the incidence of perioperative thromboembolic events. However, the effect of new oral anticoagulants on activated clotting time (ACT) in response to heparin during AF ablation in Chinese populations remains unknown. The aim of the present retrospective study was to investigate the value of ACTs in response to intraoperative heparin administration in patients using dabigatran or rivaroxaban. METHODS From January 2018 to December 2021, a total of 173 patients undergoing AF ablation were included in the study, in which 101 patients were treated with dabigatran, 72 patients were treated with rivaroxaban. The intraoperative ACT values were examined in both groups. The incidence of periprocedural complications was evaluated. RESULTS Initial heparin dosage (88 ± 19 U/kg vs. 78 ± 27 U/kg, P < 0.05), total heparin dosage (137 ± 41 U/kg vs. 106 ± 52 U/kg, P < 0.05) during the ablation procedure were higher in the dabigatran group than those in the rivaroxaban group. Mean ACT (280 ± 36 s vs. 265 ± 30 s, P < 0.05), and the percentage of ACTs within the therapeutic range (250-350 s) (74% ± 26% vs. 60% ± 29%, P < 0.05) were significantly lower in the dabigatran group than those in the rivaroxaban group, particularly in male patients. Furthermore, the average time of achieving the target ACT (250-350 s) was also found longer in the dabigatran group (P < 0.05) as compared with the rivaroxaban group. No significant difference was found in the incidence of periprocedural complications between the two groups. CONCLUSIONS The anticoagulant effect of uninterrupted rivaroxaban therapy appears to be more stable and efficient than dabigatran administration during catheter ablation in patients with AF.

Simple Summary: Urothelial carcinoma (UC) of the bladder is the most common malignancy in dialysis patients in Taiwan compared with renal cell carcinoma in Western countries. Radical cystectomy is the standard of care for localized muscle-invasive bladder cancer (MIBC), as well as for selected patients with high-risk non-MIBC. Despite improvements in anesthetic competency, surgical techniques, and postoperative care, dialysis patients undergoing radical cystectomy are at a higher risk of perioperative morbidity and mortality than non-dialysis patients. Due to the relative rarity of the condition, published data on predictors of outcome in ESRD patients undergoing radical cystectomy are scant. Our study revealed that accurate reporting of complications is necessary for preoperative counseling, identifying modifiable risk factors, and planning risk mitigation strategies. High comorbidity and low-volume surgeons were interrelated as notable risk factors for major complications. In addition to tumor-related factors, male sex, older age, and major complications significantly influence survival. Background: We investigated the use of a standardized reporting system to study perioperative complications and oncologic outcomes after radical cystectomy in end-stage renal disease (ESRD) patients with bladder cancer. Methods: We reviewed retrospective outcomes in 141 ESRD patients with bladder cancer who underwent radical cystectomy between 2004 and 2015. Complications were graded using the Clavien–Dindo classification system with 0–2 classified as "No Major Complications" and Clavien 3–5 as "Major Complications". Low-volume surgeons were classified as those performing fewer than nine cases during the study. Fisher's exact test along with the chi-squared test, two-tailed t tests, logistic regression, and the Cox proportional hazard model were used to evaluate all clinically meaningful covariates. Results: Ninety-nine (99, 70.2%) patients had no major complications, and forty-two (29.8%) patients had major complications. Patients in the major complications group were older, had a higher Charlson comorbidity index (CCI), and had a longer hospitalization duration than those in the no major complications group (all, p < 0.05). Major complications were also more common when the procedure was performed by low-volume surgeons (p = 0.003). In multivariate logistic regression models, CCI ≥ 5 (p = 0.006) and low-volume surgeon (p = 0.004) were independent predictors of major complications. According to multivariate analysis with the Cox hazards regression, male sex, age > 70 years, CCI ≥ 5, bladder cancer stage ≥ 3, lymphovascular invasion, and experiencing major complications were significant poor prognostic factors for overall survival (all, p < 0.05). Conclusions: Accurate reporting of complications is necessary for preoperative counseling, identifying modifiable risk factors, and planning risk mitigation strategies. High comorbidity and low-volume surgeons were interrelated as notable risk factors for major complications. In addition to tumor-related factors, male sex, older age, and major complications significantly influence overall survival. [ABSTRACT FROM AUTHOR]

Background: The prevalence, indications, and preferred methods for gastrocnemius recession and tendo-Achilles lengthening—grouped as triceps surae lengthening (TSL) procedures—in foot and ankle trauma are supported by a scarcity of clinical evidence. We hypothesize that injury, practice environment, and training heritage are significantly associated with probability of performing adjunctive TSL in the operative management of foot and ankle trauma. Methods: A survey was distributed to members of the American Orthopaedic Foot & Ankle Society and the Orthopaedic Trauma Association. Participants rated how likely they would be to perform TSL at initial management, definitive fixation, and after weightbearing in the presence and absence of a positive Silfverskiöld test in 10 clinical scenarios of closed foot and ankle trauma. Results: A total of 258 surgeons with median 14 years' experience responded. Eighty-five percent reported foot and ankle fellowship training, 24% reported traumatology fellowship training, 13% both, and 4% no fellowship. Ninety-nine percent reported performing TSL with a median 25 TSL procedures per year, 72% open gastrocnemius recession, and 17% percutaneous tendo-Achilles lengthening). Across all scenarios, we observed low overall 8% probability with fair agreement (κ = 0.246) of performing TSL (range, 1% at initial management of an unstable Weber B bimalleolar ankle fracture with negative contralateral Silfverskiöld test to 29% at definitive fixation of tongue-type calcaneus fracture with positive contralateral Silfverskiöld test). Silfverskiöld testing significantly influenced TSL probability at all time points. University of Washington training (β = 1.5, P =.007) but not trauma vs foot fellowship training, years in practice, academic practice, urban setting, or facility trauma designation were significantly associated with likelihood of performing TSL. Conclusion: Orthopaedic traumatology and foot and ankle surgeons report similar indications, methods, and low perceived propensity to use TSL in the management of foot and ankle trauma. We found that graduates of 1 fellowship training site were more likely to perform TSL in the setting of acute trauma potentially indicating the need for better scientific data to support this practice. Level of Evidence: Level V, therapeutic. [ABSTRACT FROM AUTHOR]

Activity-regulated cytoskeleton-associated protein (ARC) is activated by the induction of long-term potentiation and plays an important role in the synaptic plasticity of memory consolidation. Previous studies have shown that abnormal expression of ARC in the brains of patients with Alzheimer's Disease (AD) leads to the disturbance of synaptic plasticity. ARC expression is mainly regulated by transcriptional and post-translational modification. However, it is unclear whether N6-methyladenosine (m6A) engages in the epigenetic modification of ARC. The AlzData database was used to analyze the brain of AD patients, and Aβ-induced cell models were used. We revealed that ARC expression was reduced in AD patients and Aβ-induced cell models. There were five m6A modification sites of ARC mRNA that were predicted by the SRAMP database, and ARC mRNA was confirmed as the target gene of methyltransferase-like 3 (METTL3) by MeRIP. Amyloid-beta protein (Aβ) repressed the m6A modification. Knockdown of METTL3 decreased ARC mRNA m6A modification and reduced ARC protein expression, while overexpression of METTL3 rescued ARC expression after Aβ treatment. Knockdown of YTH domain family, member 1 (YTHDF1) decreased ARC protein expression, while the overexpression of YTHDF1 could not rescue the loss of ARC protein expression after 3-deazaadenosine treatment or knockdown of METTL3. Our findings identify that METTL3 rescues the Aβ-induced reduction of ARC expression via YTHDF1-Dependent m6A modification, which suggests an important mechanism of epigenetic alteration in AD.

Accurate diagnosis to limit the spread of SARS-CoV-2 is crucial for the clinical management of this lethal infection. Recently, many low-cost and easy-to-use rapid test kits (RTK) have been developed in many countries for the massive screening of SARS-CoV-2. Thus, evaluating the accuracy and reliability of an RTK is critical. The current study was conducted on 157 individuals to evaluate the performance accuracy of rapid SARS-CoV-2 antigen detection kits using different clinical samples compared with qRT-PCR results. Nasopharyngeal swabs were collected from patients for qRT-PCR and RTK tests, and then buccal and nasal, and nasal swabs were collected for RTK tests separately. The nasal and buccal swabs showed high sensitivity (98%) and specificity (100%) compared with the qRT-PCR results. Meanwhile, for nasal, the sensitivity was 96% with 98% specificity, and nasopharyngeal swabs showed 98% sensitivity and 94% specificity. Fisher's exact test revealed statistical significance (p < 0.05) between nasopharyngeal, nasal and buccal, and nasal swabs compared with qRT-PCR results. The study concludes that different clinical samples used for the rapid diagnosis of SARS-CoV-2 showed high sensitivities and specificities compared with qRT-PCR. The RTKs using nasal and buccal, nasopharyngeal, and nasal swabs are valuable tools for the early detection of SARS-CoV-2, especially when molecular detections are available with limited access and a high infectivity rate, when the timely detection of virus cases is urgently needed. These types of clinical samples are effective to be used by RTKs for surveillance among community and healthcare workers. [ABSTRACT FROM AUTHOR]

Background: This study aimed to assess and compare the depth of penetration of TotalFill BC, AH Plus Jet, and GuttaFlow Bioseal sealers into simulated lateral canals. Materials and Methods: A total of 30 extracted mandibular premolars were selected. Simulated lateral canals were made. The specimens were randomized into three experimental groups of 10 each. The specimens were cleared for visualization under a stereomicroscope at 10× magnification. The depth of penetration was assessed by a four-grade scoring system. Data were submitted to Fisher exact test at 5% significance. Results: There was statistically no significant difference among the experimental groups regarding the depth of penetration (P> .05). Conclusion: All root canal sealers experimented with herein showed a comparable depth of penetration in the simulated lateral canals regarding their filling ability. [ABSTRACT FROM AUTHOR]

Objective: To establish the diagnostic biomarker of electroencephalogram (EEG) to distinguish between anti- N -methyl-d-aspartate receptor encephalitis (NMDARE) and other types of autoimmune encephalitis (other AEs). Methods: We reviewed the clinical records of 90 patients with acute encephalitis who were treated in our institution between January 2014 and October 2020. We enrolled the patients who fulfilled the diagnostic criteria for possible AE (pAE) defined by Graus et al. (pAE criteria) and then classified into definite NMDARE and other AEs. We investigated the main syndrome and analyzed all admission EEGs using EEG power value (PV). Statistical significance was tested using the Mann–Whitney U test or Fisher's exact test. Results: Twenty-five patients fulfilled the pAE criteria and were classified into 9 with definite NMDARE (median age: 21 years; 8 women) and 12 with other AEs (median age: 37.5 years; 6 women). Four were eventually excluded. Speech dysfunction (9/9 vs. 4/12, p = 0.005) and movement disorders (6/9 vs. 1/12, p = 0.016) were more frequent in NMDARE than in other AEs. The PV analyses revealed the novel quantitative EEG (qEEG) index, namely, fast slow ratio (FSR) (PV of total beta/PV of total theta + delta). The median FSR (0.139 vs. 0.029, p = 0.004) was higher for NMDARE than other AEs, and the receiver operating characteristic curve area of FSR was 0.86 (95% CI 0.70–1.00). A cutoff value of 0.047 yielded a specificity of 0.75 and a sensitivity of 1.00. Focusing on patients who did not meet the "probable NMDARE criteria" in Graus 2016 (proNMDARE criteria) (n = 10), the pretest probability of NMDAR antibody test was 0.30 (3/10), which increased in patients with an FSR greater than the cutoff (n = 5) to 0.60 (3/5). Conclusions: The NMDARE group highlighted speech dysfunction and movement disorders, and a novel qEEG index FSR accurately distinguished the NMDARE patients from other AEs. The FSR is a promising diagnostic marker for NMDARE that indicates the positive results of NMDAR antibodies in patients with AE when combined with the proNMDARE criteria. [ABSTRACT FROM AUTHOR]

Objective: the care of adolescents with or without a chronic disease must complete, standardized and focused on individual demands and the transition process to adult care and adherence to treatment. This study aimed to characterize the care provided by nurses from the state of São Paulo who work with adolescents. Method: this is a cross-sectional and descriptive study on the care provided to adolescents by nurses in São Paulo, based on the answers to a self-administered questionnaire, available in the REDCap tool between August 2018 and October 2019. Results: participants answered 1632 questionnaires. Only 38% of nurses work with adolescents, 11.2% exclusively. Professionals were divided according to the median length of professional experience in groups A and B (≤5 years and >5 years). Drug addiction (p=0.01) and working with a multidisciplinary team (p=0.04) were significantly more reported in group B. Routine follow-up (p=0.02) and questioning about sexual or physical violence (p=0.03) were significantly more performed by professionals from group A. Conclusion: this study identified the need for a care protocol that can be replicated on a large scale and that includes the treatment and the particularities of adolescents to improve adherence and the transition into adult care.

Introduction: Morbidity and mortality benefits have been associated with prompt surgical treatment of geriatric hip fractures. The purpose of this study was to evaluate the impact of early (&#8804=;24 hr) vs delayed (>24 hr) time to operating room(TTOR) on 1) hospital length of stay and 2) total and post-operative opiate use in geriatric hip fractures. Materials and Methods: This study was a retrospective review of patients ≥65 years-old at the time of admission for surgery for hip fracture at a Level II academic trauma center. Outcome measures were length of stay (LOS), oral morphine equivalents (OME) throughout hospitalization. Patients were stratified into early and delayed TTOR groups and comparisons were made between groups. Results: Between the early (n = 75, 80.6%) and late (n = 18, 19.4%) groups, there were no differences in age, fracture pattern, type of treatment, preoperative opiate use, and perioperative non-oral pain management. The early group trended toward shorter total LOS (108.0 ± 67.2 hours vs 144.8 ± 103.7 hours, P = .066), but not post-operative LOS. Total OME usage was less in the early intervention group (92.5 ± 188.0 vs 230.2 ± 296.7, P = .015), in addition to reduced post-operative OME (81.3 ± 174.9 vs 213.3 ± 271.3, P = .012). There were no differences in evaluated potential delay sources such as primary language, use of surrogate decision makers, or need for advanced imaging. Discussion: Surgical treatment of geriatric hip/femur fractures in =24 hours from presentation is achievable and may be associated with reduced total inpatient opiate use, although daily use did not differ. Conclusion: Establishing institutional TTOR goals as part of an interdisciplinary hip fracture co-management clinical pathway can facilitate prompt care and contribute to recovery and less opiate use in these patients with highly morbid injuries.

Background Interactions between genetic and nutritional factors can contribute to the risk of gestational diabetes mellitus (GDM). Objectives We aimed to explore the associations of cyclin-dependent kinase 5 regulatory subunit associated protein 1-like 1 (CDKAL1) single-nucleotide polymorphism (SNP) rs7747752 and serum concentrations of SFAs with the risk of GDM in Chinese women. Methods We conducted a 1:1 case–control study in a prospective cohort of pregnant women in Tianjin, China. Serum SFA data were collected from a total of 243 women with GDM and their controls matched by maternal age (±1 y). Among them, 207 case–control pairs had high-quality sequencing data. P/L and S/P ratios were defined as palmitic acid (16:0)/lauric acid (12:0) and stearic acid (18:0)/palmitic acid, respectively. Conditional logistic regression analysis was performed to estimate associations of CDKAL1 SNP rs7747752 and serum concentrations of SFAs with the risk of GDM. An additive interaction between rs7747752 and palmitic acid was analyzed to test the contribution of their interaction to the risk of GDM. Results Among the 5 tested SFAs, palmitic acid was positively whereas lauric acid was negatively associated with the risk of GDM. A P/L ratio ≥12.2 and an S/P ratio ≤0.71 were independently and synergistically associated with an increased risk of GDM. The CDKAL1 rs7747752 G > C variant was significantly associated with an increased risk of GDM (P  < 0.05). Furthermore, the presence of the rs7747752 G > C variant increased the OR (95% CI) of high palmitic acid concentration from 1.55 (0.61, 3.97) to 4.34 (2.04, 9.23), with a significant additive interaction. Conclusions The interaction between high serum palmitic acid concentration and the CDKAL1 rs7747752 G > C variant played a critical role in GDM. Given that a hypocaloric low-carbohydrate diet can lower palmitic acid concentrations, it is worthwhile to test whether such a diet is effective in reducing the risk of GDM, especially among women who have both risk factors.

Background: Urinary catheters (UCs) with a closed urinary drainage system have been widely used in patients for many years. However, the frequency of replacing and operating these devices may be associated with catheter-associated urinary tract infection (CAUTI). Purpose: This study was designed to compare the incidence of CAUTI by replacement time (every 14 or ≥ 15 days) of the urinary drainage system. Methods: This 1-year prospective, nonrandomized controlled study was conducted in a major teaching hospital. The Transparent Reporting of Evaluations with Nonrandomized Designs Statement checklist was used. All of the patients with UCs were divided into two groups based on each patient's preference with regard to replacement time of the urinary drainage system. Results: Five hundred sixty-two patients were evaluated, and 341 patients with UCs were enrolled as participants in the study. In the per-protocol analysis, 16 patients (22.2%; 9.3 episodes/ 1,000 catheter-days) in the 14-day group and 15 patients (17.9%; relative risk = 1.24, 95% confidence interval [0.66, 2.34]) in the ≥ 15-day group (7.7 episodes/1,000 catheter-days; incidence density ratio 1.20, 95%confidence interval [0.60, 2.43]) had CAUTIs. A comparison of cleanliness within urinary bags showed no significant intergroup difference (p > .05). In the intention-to-treat analysis, the incidence of CAUTI between the two groups was also not significantly different (p > .05). Conclusions: No statistically significant difference in the incidence of CAUTI was identified between patients who used the 14-day replacement interval and those who used the ≥ 15-day replacement interval for their urinary drainage system.

Aim: This ex vivo study was designed to evaluate and compare different endodontic irrigation and activation systems, the self-adjusting file (SAF) instrumentation/irrigation system, and XP-endo finisher for removal of intracanal smear layer. Materials and Methods: Fifty recently extracted, noncarious human intact single-rooted premolars were selected and divided into five groups (n = 10) according to the root canal irrigation systems; syringe and needle irrigation, passive ultrasonic irrigation (PUI), EndoVac irrigation system, SAF system, and XP-endo finisher. All groups were prepared to apical size F4 file except for the SAF group which was prepared to apical size 20 K-file and then instrumented with the SAF file. Each sample was subjected to final irrigation using different irrigation/activation systems. After splitting the samples, one half of each root was selected for examination under scanning electron microscope. The irrigation systems were compared using the Fisher's exact test with significance set at P < 0.05. Results: In the coronal part, there was no difference among the groups. In the mid-root section, the results of the PUI, EndoVac, SAF, and XP-endo finisher groups tended to be better than syringe and needle irrigation, but the difference was not significant. The apical part of the canal, the SAF system, and XP-endo finisher group seemed to be cleaner than those of the EndoVac group, but this difference was not significant. Conclusions: Within the limitations of the present study, SAF system and XP-endo finisher group cleaned the apical part of the canal more efficiently than EndoVac, PUI, and syringe and needle irrigation.

Aim: To examine the effects of neonatal simulation‐based practice by applying flipped learning based on Tanner's clinical judgement model to pre‐simulation briefing for nursing students. Design: A quasi‐experimental non‐equivalent control group pre‐ and postintervention design. Methods: Using Tanner's clinical judgment model, flipped learning was developed and applied to the pre‐simulation briefing curriculum prior to the neonatal nursing simulation exercise. Flipped learning was compared with a general pre‐simulation briefing with 65 South Korean students. From September 7, 2019, to October 25, 2019. Results: The experimental group's critical thinking, self‐confidence and clinical judgement ability increased, but knowledge, satisfaction and anxiety did not differ from that of the control group. Pre‐simulation briefing design focuses on improving students' environmental comfort and reducing anxiety rather than developing complex reasoning skills and clinical judgement abilities. Applying flipped learning based on Tanner's clinical judgement model to pre‐simulation briefing increased critical thinking, self‐confidence and clinical judgement ability. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to investigate the methodology, interpretation, and perceived value of Spurling's test toward diagnosis/classification and treatment. Methods: An anonymous web-based survey was made available to physical therapist members of the Academy of Orthopaedic Physical Therapy of the American Physical Therapy Association. Based on video demonstrations of technique and symptom distribution, questions included preferred method, criteria for test interpretation, and perceived value of Spurling's test and other examination findings toward clinical decision-making. Professional profile data were also collected. Results: Among the 452 participants completing the survey, no method of testing was preferred by more than 37%, with ipsilateral lateral flexion, rotation, and extension with compression being most frequently preferred followed by ipsilateral lateral flexion with compression at 32%. Proximal provocation of symptoms only without distal symptoms was interpreted as a positive test by 67%. Participants rated Spurling's test of moderate to low value toward diagnosis/classification and treatment. Discussion: Inconsistency with methodology and interpretation of Spurling's test is suggested to be pervasive in physical therapist practice. While an optimal test methodology has yet to be identified, result interpretation does have a basis for clarification toward diagnosis/classification and reduction of unwanted variance in practice.
