High-Intensity Aphasia Intervention Is Minimally Fatiguing in Chronic Aphasia: An Analysis of Participant Self-Ratings From a Large Randomized Controlled Trial.

BACKGROUND: High-intensity therapy is recommended in current treatment guidelines for chronic poststroke aphasia. Yet, little is known about fatigue levels induced by treatment, which could interfere with rehabilitation outcomes. We analyzed fatigue experienced by people with chronic aphasia (>6 months) during high-dose interventions at 2 intensities. METHODS: A retrospective observational analysis was conducted on self-rated fatigue levels of people with chronic aphasia (N=173) collected during a previously published large randomized controlled trial of 2 treatments: constraint-induced aphasia therapy plus and multi-modality aphasia therapy. Interventions were administered at a higher intensity (30 hours over 2 weeks) or lower intensity (30 hours over 5 weeks). Participants rated their fatigue on an 11-point scale before and after each day of therapy. Data were analyzed using Bayesian ordinal multilevel models. Specifically, we considered changes in self-rated participant fatigue across a therapy day and over the intervention period. RESULTS: Data from 144 participants was analyzed. Participants were English speakers from Australia or New Zealand (mean age, 62 [range, 18-88] years) with 102 men and 42 women. Most had mild (n=115) or moderate (n=52) poststroke aphasia. Median ratings of the level of fatigue by people with aphasia were low (1 on a 0-10-point scale) at the beginning of the day. Ratings increased slightly (+1.0) each day after intervention, with marginally lower increases in the lower intensity schedule. There was no evidence of accumulating fatigue over the 2- or 5-week interventions. CONCLUSIONS: Findings suggest that intensive intervention was not associated with large increases in fatigue for people with chronic aphasia enrolled in the COMPARE trial (Constraint-Induced or Multimodality Personalised Aphasia Rehabilitation). Fatigue did not change across the course of the intervention. This study provides evidence that intensive treatment was minimally fatiguing for stroke survivors with chronic aphasia, suggesting that fatigue is not a barrier to high-intensity treatment.

Timing of development of osteoradionecrosis post head and neck radiotherapy: does a safe time interval exist for dental extraction?

INTRODUCTION: Risk factors for developing osteoradionecrosis (ORN) are well known, but less is known about factors influencing the interval between radiotherapy and the onset of ORN. Also, it is unknown whether there is any specific period post-radiotherapy with a reduced probability of ORN when irradiated teeth require extraction. PURPOSE: The primary aim of this study was to identify factors influencing the interval in developing ORN in the following subgroups of patients: (1) patients who spontaneously developed ORN, (2) surgical-intervention-related ORN with a particular focus on patients after mandibulectomy. The secondary aim was to attempt to identify a possible time for safer dental intervention after primary treatment. MATERIALS AND METHODS: The authors retrospectively analysed 1608 head and neck cancer (HNC) patients treated in a single centre. Time intervals were measured from the end of radiotherapy to the development of ORN and further analysed in the subgroups listed above. RESULTS: In all, 141 patients (8.8%) developed intra-oral ORN. Median time from radiotherapy to ORN development in the whole cohort was 9 months. Median interval for spontaneous ORN was 8 months, 6.5 months for intervention-related ORN, and 15 months for patients post-mandibulectomy. In patients who required dental extraction preradiotherapy, median interval of ORN onset was 5 months. CONCLUSION: In our study, a slightly higher proportion of patients with intervention developed ORN earlier in comparison with spontaneous ORN. The period from 12-18 months after radiotherapy was identified as having the highest probability of developing ORN in patients after mandibulectomy. A time for safer dental intervention after primary treatment was not identified.

Optimizing the Time and Dose of Melatonin as a Sleep-Promoting Drug: A Systematic Review of Randomized Controlled Trials and Dose-Response Meta-Analysis.

Previous studies have reported inconsistent results about exogenous melatonin's sleep-promoting effects. A possible explanation relies on the heterogeneity in administration schedule and dose, which might be accountable for differences in treatment efficacy. In this paper, we undertook a systematic review and meta-analysis of double-blind, randomized controlled trials performed on patients with insomnia and healthy volunteers, evaluating the effect of melatonin administration on sleep-related parameters. The standardized mean difference between treatment and placebo groups in terms of sleep onset latency and total sleep time were used as outcomes. Dose-response and meta-regression models were estimated to explore how time of administration, dose, and other treatment-related parameters might affect exogenous melatonin's efficacy. We included 26 randomized controlled trials published between 1987 and 2020, for a total of 1689 observations. Dose-response meta-analysis showed that melatonin gradually reduces sleep onset latency and increases total sleep time, peaking at 4 mg/day. Meta-regression models showed that insomnia status (ß = 0.50, p < 0.001) and time between treatment administration and the sleep episode (ß = -0.16, p = 0.023) were significant predictors of sleep onset latency, while the time of day (ß = -0.086, p < 0.01) was the only significant predictor of total sleep time. Our results suggest that advancing the timing of administration (3 h before the desired bedtime) and increasing the administered dose (4 mg/day), as compared to the exogenous melatonin schedule most used in clinical practice (2 mg 30 min before the desired bedtime), might optimize the efficacy of exogenous melatonin in promoting sleep.

Relationship between observation time and detection rate of focal lesions in Esophagogastroduodenoscopy: a single-center, retrospective study.

BACKGROUND: Current studies have shown that longer observation time can improve neoplastic detection rate. This study aimed to clarify whether endoscopists with longer observation times can detect more focal lesions. METHODS: Based on the mean examination time for Esophagogastroduodenoscopy (EGD) without biopsy, endoscopists were divided into fast and slow groups, and the detection rate of focal lesions was compared between the two groups. Univariate analysis, multivariate analysis and restricted cubic spline were used to explore the factors of focal lesion detection rate. RESULTS: Mean examination time of EGD without biopsy was 4.5 min. The cut-off times used were 5 min. 17 endoscopists were classified into the fast (4.7 ± 3.6 min), and 16 into the slow (7.11 ± 4.6 min) groups. Compared with fast endoscopists, slow endoscopists had a higher detection rate of focal lesions (47.2% vs. 51.4%, P < 0.001), especially in the detection of gastric lesions (29.7% vs. 35.9%, P < 0.001). In univariate and multivariate analyses, observation time, patient age and gender, expert, biopsy rate, and number of images were factors in FDR. There is a nonlinear relationship between observation time and FDR. CONCLUSION: Longer examination time improves the detection rate of focal lesions. Observation time is an important quality indicator of the EGD examination.

Effects of extraoral storage time on autologous gingival graft early healing: A split-mouth randomized study.

AIMS: Despite the established use of palatal tissue grafts for mucogingival procedures, there are no studies on the effect of extraoral storage time on graft outcomes. This prospective split-mouth randomized experimental clinical trial aimed to assess whether gingival graft extraoral storage time affects graft healing. METHODS: Standardized grafts were harvested from the palate and stored extraorally for 2 (Control) or 40 (Test) minutes before being placed at recipient beds. Intraoral scans, clinical photographs, and tissue blood perfusion were obtained preoperatively, postoperatively, and at follow-up visits (Days 2 (PO2), 3 (PO3), 7 (PO7), and 14 (PO14)). Healing Score Index (HSI) and wound fluid (WF) biomarkers (angiogenin, IL-6, IL-8 (CXCL8), IL-33, VEGF-A, and ENA-78 (CXCL5)) were also assessed. RESULTS: Twenty-three participants completed all study visits. Extraoral storage time was 2.3 ± 1.1 min and 42.8 ± 3.4 min for C and T grafts, respectively (p < .0001). Recipient beds remained open for 21.4 ± 1.7 min. No graft underwent necrosis or failed to heal by PO14. Minimal volumetric changes were observed, without significant intergroup differences (p ≥ .11). Graft perfusion initially decreased post-harvesting before peaking on PO7 for both C and T grafts, with no significant intergroup differences (p ≥ .14). HSI values progressively increased, with no significant intergroup differences (p ≥ .22). WF analysis revealed detectable levels for all biomarkers tested, without significant intergroup differences (p ≥ .23). CONCLUSION: Extraoral storage time of 40 min has neither statistically significant nor clinically discernible effects on autologous graft revascularization, early healing, or survival, as determined by physiological, wound healing, and molecular parameters.

Diagnostic performance of the CellaVision preclassification neutrophil count - time to bypass the reclassification?

OBJECTIVES: The objective of this study was to perform a method comparison between the CellaVision preclassification neutrophil count and the reclassification neutrophil count performed by trained laboratory technicians, and to evaluate the diagnostic performance of the preclassification neutrophil count at clinical decision levels. METHODS: We retrospectively identified patient samples through 2019-2022 in which the differential count was performed on Cellavision (n = 4,354). Data on sample characteristics and leukocyte- and differential counts was extracted from the electronic medical journal. For each sample, data containing the pre- and reclassification leukocyte classification, respectively, was extracted from the Cellavision software. Method comparison between the pre-and reclassification neutrophil count was performed using Bland Altman analysis. Diagnostic performance of the preclassification neutrophil count was evaluated according to four pre-specified categories of results with the reclassification as reference method. RESULTS: The median difference between the pre- and reclassification neutrophil count was 0.044 x 109/L. The preclassification neutrophil count categorised 95.6% of all samples correctly according to the four categories. The sensitivity, specificity, positive predictive value and negative predictive value for detecting neutrophilia > 7.00 x 109/L was 98.8%, 97.2%, 95.8%, and 99.2%, respectively. In samples with leukopenia (n = 543), the sensitivity, specificity, positive predictive value and negative predictive value for detecting severe neutropenia (< 0.50 x 109/L) was 97.7%, 99.1%, 98.6%, and 98.5%, respectively. CONCLUSION: The diagnostic performance of the CellaVision preclassification neutrophil count was satisfactory. The preclassification neutrophil count may be released to the electronic medical journal to improve turnaround time and benefit laboratory management.

Postoperative Time and Anatomic Location Influence Skin Graft Reperfusion Assessed With Laser Speckle Contrast Imaging.

OBJECTIVES: Under optimal conditions, afferent and efferent human skin graft microcirculation can be restored 8-12 days postgrafting. Still, the evidence about the reperfusion dynamics beyond this period in a dermato-oncologic setting is scant. We aimed to characterise the reperfusion of human skin grafts over 4 weeks according to the necrosis extension (less than 20%, or 20%-50%) and anatomic location using laser speckle contrast imaging (LSCI). METHODS: Over 16 months, all eligible adults undergoing skin grafts following skin cancer removal on the scalp, face and lower limb were enroled. Perfusion was assessed with LSCI on the wound margin (control skin) on day 0 and on the graft surface on days 7, 14, 21 and 28. Graft necrosis extension was determined on day 28. RESULTS: Forty-seven grafts of 47 participants were analysed. Regardless of necrosis extension, graft perfusion equalled the control skin by day 7, surpassed it by day 21, and stabilised onwards. Grafts with less than 20% necrosis on the scalp and lower limb shared this reperfusion pattern and had a consistently better-perfused centre than the periphery for the first 21 days. On the face, the graft perfusion did not differ from the control skin from day 7 onwards, and there were no differences in reperfusion within the graft during the study. CONCLUSION: Skin graft reperfusion is a protracted process that evolves differently in the graft centre and periphery, influenced by postoperative time and anatomic location. A better knowledge of this process can potentially enhance the development of strategies to induce vessel ingrowth into tissue-engineered skin substitutes.

Critical Period After Stroke Study (CPASS): A phase II clinical trial testing an optimal time for motor recovery after stroke in humans.

Restoration of human brain function after injury is a signal challenge for translational neuroscience. Rodent stroke recovery studies identify an optimal or sensitive period for intensive motor training after stroke: near-full recovery is attained if task-specific motor training occurs during this sensitive window. We extended these findings to adult humans with stroke in a randomized controlled trial applying the essential elements of rodent motor training paradigms to humans. Stroke patients were adaptively randomized to begin 20 extra hours of self-selected, task-specific motor therapy at ≤30 d (acute), 2 to 3 mo (subacute), or ≥6 mo (chronic) after stroke, compared with controls receiving standard motor rehabilitation. Upper extremity (UE) impairment assessed by the Action Research Arm Test (ARAT) was measured at up to five time points. The primary outcome measure was ARAT recovery over 1 y after stroke. By 1 y we found significantly increased UE motor function in the subacute group compared with controls (ARAT difference = +6.87 ± 2.63, P = 0.009). The acute group compared with controls showed smaller but significant improvement (ARAT difference = +5.25 ± 2.59 points, P = 0.043). The chronic group showed no significant improvement compared with controls (ARAT = +2.41 ± 2.25, P = 0.29). Thus task-specific motor intervention was most effective within the first 2 to 3 mo after stroke. The similarity to rodent model treatment outcomes suggests that other rodent findings may be translatable to human brain recovery. These results provide empirical evidence of a sensitive period for motor recovery in humans.

Time course of CYP3A activity during and after metamizole (dipyrone) in healthy volunteers.

AIMS: In patients of all ages, metamizole is a frequently used analgesic. Recently, metamizole has been identified as an inducer of, among others, cytochrome P450 (CYP) 3A activity, but the time course of this interaction has not been evaluated. METHODS: Using repeated oral microdoses (30 µg) of the CYP3A index substrate midazolam, we assessed changes in midazolam pharmacokinetics (area under the concentration-time curve from 2-4 h: AUC2-4 and estimated partial metabolic clearance: eClmet ) before, at steady-state, and after discontinuation of 3 × 1000 mg metamizole/day orally for 8 days. RESULTS: Significant changes in pharmacokinetic parameters were detected already 3 days after start of metamizole treatment. At the steady-state of enzyme induction, the geometric mean ratio of midazolam AUC2-4 was substantially reduced to 0.18 (90% confidence interval: 0.14-0.24) with a corresponding 5.43-fold (4.15-7.10) increase of eClmet . After discontinuation of metamizole, the changes slowly recovered, but were still significant at the end of the observation period on the fifth day after discontinuation of metamizole therapy (AUC2-4 reduced to 0.50 [0.41-0.63] and eClmet 1.99-fold increased [1.60-2.47, P < 0.05]). CONCLUSION: Metamizole acts as a strong inducer of CYP3A already few days after start of metamizole administration and, thus, should be avoided in patients using drugs with narrow therapeutic index and major clearance via CYP3A. If their administration is essential, close monitoring and dose adjustment of comedication should be performed as early as the first week after the initiation and after discontinuation of metamizole therapy.

Treatment Delays and Chance of Reperfusion Therapy in Patients with Acute Stroke: A Danish Nationwide Study.

INTRODUCTION: We aimed to determine the treatment delay for ischemic stroke patients in Denmark. METHODS: A nationwide register-based study on acute ischemic stroke patients admitted through emergency medical services. Treatment delay comprised patient, prehospital, and in-hospital delay. Analyses were stratified according to length of prehospital delay (<3 vs. ≥3 h). RESULTS: A total of 5,356 ischemic stroke episodes were included. The median onset-to-door time was 187 min, and 2,405 (43%) arrived at the stroke unit within 3 h. Overall, the median patient delay was 115 min. For early arrival (n = 2,280), patient delay was 27 min compared to 437 min for late arrivals (n = 2,448). Median prehospital delay varied by 9 min between early- and late-arriving patients. Approximately 48% of the early-arriving patients compared to 9% of the late-arriving patients received i.v. thrombolysis. For thrombectomy, the numbers were 10% and 3%, respectively. This corresponded to an unadjusted relative risk (RR) of 0.18 (95% CI: 0.16-0.21) and adjusted (age, sex, cohabitation status, and stroke severity) RR of 0.20 (95% CI: 0.18-0.23) for i.v. thrombolysis when comparing patients arriving later than 3 h with patients arriving earlier. For thrombectomy, the unadjusted and adjusted RRs were 0.30 (95% CI: 0.23-0.39) and 0.40 (95% CI: 0.31-0.52), respectively. CONCLUSIONS: Patient delay remains the most important barrier for use of reperfusion therapy among acute ischemic stroke patients calling 1-1-2, whereas system delay seems independent of patient delay.

Polyps are detected more often in early colonoscopies.

OBJECTIVE: To examine the time variation in polyp detection for colonoscopies performed in a tertiary hospital and to explore independent factors that predict polyp detection rate (PDR). METHODS: Data on all patients who underwent colonoscopy for the diagnostic purpose at our endoscopy center in Zhongnan Hospital of Wuhan University from January 2021 to December 2021 were reviewed. The start time of included colonoscopies for eligible patients was recorded. PDR and polyps detected per colonoscopy (PPC) were calculated. The endoscopists' schedules were classified into full-day and half-day shifts according to their participation in the morning and afternoon colonoscopies. RESULTS: Data on a total of 12116 colonoscopies were analyzed, with a PDR of 38.03% for all the patients and 46.38% for patients ≥50 years. PDR and PPC significantly decreased as the day progressed (both p < .001). For patients ≥50 years, PDR declined below 40% at 13:00-13:59 and 16:00-16:59. The PDR in the morning was higher than that in the afternoon for both half-day (p = .019) and full-day procedures (p < .001). In multivariate analysis, start time, patient gender, age, conscious sedation, and bowel preparation quality significantly predicted PDR (p < .001). CONCLUSIONS: The polyp detection declined as the day progressed. A continuous work schedule resulted in a subpar PDR. Colonoscopies performed in the morning had a higher PDR than that in the afternoon. Patient gender, age, conscious sedation, and bowel preparation quality were identified as the independent predictors of PDR.

Sample size estimation in clinical trials using ventilator-free days as the primary outcome: a systematic review.

BACKGROUND: Ventilator-free days (VFDs) are a composite endpoint increasingly used as the primary outcome in critical care trials. However, because of the skewed distribution and competitive risk between components, sample size estimation remains challenging. This systematic review was conducted to systematically assess whether the sample size was congruent, as calculated to evaluate VFDs in trials, with VFDs' distribution and the impact of alternative methods on sample size estimation. METHODS: A systematic literature search was conducted within the PubMed and Embase databases for randomized clinical trials in adults with VFDs as the primary outcome until December 2021. We focused on peer-reviewed journals with 2021 impact factors greater than five. After reviewing definitions of VFDs, we extracted the sample size and methods used for its estimation. The data were collected by two independent investigators and recorded in a standardized, pilot-tested forms tool. Sample sizes were calculated using alternative statistical approaches, and risks of bias were assessed with the Cochrane risk-of-bias tool. RESULTS: Of the 26 clinical trials included, 19 (73%) raised "some concerns" when assessing risks of bias. Twenty-four (92%) trials were two-arm superiority trials, and 23 (89%) were conducted at multiple sites. Almost all the trials (96%) were unable to consider the unique distribution of VFDs and death as a competitive risk. Moreover, significant heterogeneity was found in the definitions of VFDs, especially regarding varying start time and type of respiratory support. Methods for sample size estimation were also heterogeneous, and simple models, such as the Mann-Whitney-Wilcoxon rank-sum test, were used in 14 (54%) trials. Finally, the sample sizes calculated varied by a factor of 1.6 to 17.4. CONCLUSIONS: A standardized definition and methodology for VFDs, including the use of a core outcome set, seems to be required. Indeed, this could facilitate the interpretation of findings in clinical trials, as well as their construction, especially the sample size estimation which is a trade-off between cost, ethics, and statistical power.

Predictors of successful discontinuation of continuous kidney replacement therapy in a pediatric cohort.

BACKGROUND: Recognizing the optimal time to discontinue continuous kidney replacement therapy (CKRT) is necessary to advance patient recovery and mitigate complications. The aim of this study was to identify predictors of successful CKRT cessation in pediatric patients. METHODS: All patients requiring CKRT between January 2010 and March 2021 were evaluated. Patients on peritoneal or hemodialysis, who transferred between institutions, or who did not trial off CKRT were excluded. Successful discontinuation was defined as remaining off CKRT for at least 7 days. Demographics, admission diagnoses, PRISM III scores, and reasons for CKRT initiation were obtained. Clinical and biochemical variables were evaluated at CKRT initiation and discontinuation and in the 12-h period following discontinuation. Comparisons were conducted using Wilcoxon rank sum and Fisher's exact tests for continuous and categorical variables, respectively. A logistic regression model was fitted to identify significant factors. RESULTS: Ninety-nine patients underwent a trial off CKRT. Admission and initiation characteristics of the success and failure groups were similar. Patients who required re-initiation (n = 26) had longer ICU lengths of stay (27.2 vs. 44.5 days, p = 0.046) and higher in-hospital mortality (15.1% vs. 46.2%, p = 0.002). Urine output greater than 0.5 mL/kg/h irrespective of diuretic administration in the 6-h period before CKRT discontinuation was a significant predictor (AUC 0.72, 95% CI 0.60-0.84, p = 0.0009). CONCLUSIONS: Determining the predictors of sustained CKRT discontinuation is critical. Urine output greater than 0.5 mL/kg/h in this pediatric cohort predicted successful discontinuation. Future studies are needed to validate this threshold in disease- and age-specific cohorts and evaluate additional biomarkers of kidney injury. A higher resolution version of the Graphical abstract is available as Supplementary information.

Effects of delayed cord clamping at different time intervals in late preterm and term neonates: a randomized controlled trial.

Delayed cord clamping (DCC) at delivery has well-recognized benefits; however, current scientific guidelines lack uniformity in its definition. This parallel-group, three-arm assessor-blinded randomized controlled trial compared the effects of three different timings of DCC at 30, 60, and 120 s on venous hematocrit and serum ferritin levels in late preterm and term neonates not requiring resuscitation. Eligible newborns (n = 204) were randomized to DCC 30 (n = 65), DCC 60 (n = 70), and DCC 120 (n = 69) groups immediately after delivery. The primary outcome variable was venous hematocrit at 24 ± 2 h. Secondary outcome variables were respiratory support, axillary temperature, vital parameters, incidences of polycythemia, neonatal hyperbilirubinemia (NNH), need and duration of phototherapy, and postpartum hemorrhage (PPH). Additionally, serum ferritin levels, the incidence of iron deficiency, exclusive breastfeeding (EBF) rate, and anthropometric parameters were assessed during post-discharge follow-up at 12 ± 2 weeks. Over one-third of the included mothers were anemic. DCC 120 was associated with a significant increase in the mean hematocrit by 2%, incidence of polycythemia, and duration of phototherapy, compared to DCC30 and DCC60; though the incidence of NNH and need for phototherapy was similar. No other serious neonatal or maternal adverse events including PPH were observed. No significant difference was documented in serum ferritin, incidences of iron deficiency, and growth parameters at 3 months even in the presence of a high EBF rate.   Conclusion: The standard recommendation of DCC at 30-60 s may be considered a safe and effective intervention in the busy settings of low-middle-income countries with a high prevalence of maternal anemia.   Trial registration: Clinical trial registry of India (CTRI/2021/10/037070). What is Known: • The benefits of delayed cord clamping (DCC) makes it an increasingly well-accepted practice in the delivery room. • However, uncertainty continues regarding the optimal timing of clamping; this may be of concern both in the neonate and the mother. What is New: • DCC at 120 s led to higher hematocrit, polycythemia and longer duration of phototherapy, without any difference in serum ferritin, and incidence of iron deficiency. • DCC at 30-60 s may be considered a safe and effective intervention in LMICs.

Comparison of Rehabilitation Training at Different Timepoints to Restore Shoulder Function in Patients With Breast Cancer After Lymph Node Dissection: A Randomized Controlled Trial.

OBJECTIVE: To investigate whether advancing the initiation of rehabilitation training compared with the time recommended by the guidelines after breast cancer (BC) surgery is beneficial to the recovery of shoulder function and quality of life. DESIGN: Prospective, observational, single center, randomized controlled trial. SETTING: The study was conducted between September 2018 and December 2019, with a 12-week supervised intervention and 6-week home-exercise period concluding in May 2020. PARTICIPANTS: Two hundred BC patients received axillary lymph node dissection (N=200). INTERVENTIONS: Participants were recruited and randomly allocated into 4 groups (A, B, C, and D). Group A started range of motion (ROM) training at 7 days postoperative and progressive resistance training (PRT) at 4 weeks postoperative; group B started ROM training at 7 days postoperative and PRT at 3 weeks postoperative; group C started ROM training at 3 days postoperative and PRT at 4 weeks postoperative; and group D started ROM training at 3 days postoperative and PRT at 3 weeks postoperative. MAIN OUTCOME MEASURES: The primary outcome measure was Constant-Murley Score. Secondary outcome measures included ROM, shoulder strength, grip, European Organization Research and Treatment of Cancer breast cancer-specific quality-of-life questionnaire module (EORTC QLQ-BR23), and SF-36. Incidence of adverse reactions (drainage and pain) and complications (ecchymosis, subcutaneous hematoma, lymphedema) were also assessed. RESULTS: Participants who started ROM training at 3 days postoperative obtained more benefits in mobility, shoulder function, and EORTC QLQ-BR23 score, while patients who started PRT at 3 weeks postoperative saw improvements in shoulder strength and SF-36. Incidence of adverse reactions and complications were low in all 4 groups, with no significant differences among the 4 groups. CONCLUSIONS: Advancing ROM training initiation to 3 days postoperative or PRT to 3 weeks postoperative can better restore shoulder function after BC surgery and lead to faster quality of life improvement.

Educational efficacy of medical humanities in empathy of medical students and healthcare professionals: a systematic review and meta-analysis.

BACKGROUND: Medical humanities education is an important part of medical education. The purpose of this study was to determine the effectiveness of medical humanities in improving empathy among medical students and healthcare professionals. METHODS: PubMed, Embase, EBSCO-ERIC, Web of Science were searched systematically for studies in the English language. The last retrieval date is May 1, 2023. Best Evidence Medical Education (BEME) Global Rating Scale and Kirkpatrick-based results were used to evaluate the quality of literature. In this study, a meta-analysis of continuous data was conducted. RESULTS: The pooled results by single-arm test meta-analysis showed a benefit with medical humanities programs in empathy (SMD 1.33; 95% CI 0.69-1.96). For single-arm trials of medical humanities program interventions of less than 4 months, 4 months to 12 months, and more than one year, the standardized mean differences(SMD) between post-test and pre-test were 1.74 (P < 0.05), 1.26 (P < 0.05), and 0.13 (P = 0.46), respectively. The results showed a significant difference in the effect of medical humanities programs on male and female empathy (SMD - 1.10; 95% CI -2.08 - -0.13). The SMDs for the study of course, the course combined reflective writing, and the course combined reflective writing and practice as intervention modalities for medical humanities programs were 1.15 (P < 0.05), 1.64 (P < 0.05), and 1.50 (P < 0.05), respectively. CONCLUSION: Medical humanities programs as a whole can improve the empathy of medical students and health professionals. However, different intervention durations and different intervention methods produce different intervention effects.

Association between long working hours and unmet dental needs in wage workers.

BACKGROUND: Many previous studies on the reasons behind unmet dental needs focus on economic issues. However, in this research, we aimed to investigate the relationship between long working hours and unmet dental needs while considering the influence of occupational factors in wage workers. METHODS: This study used data from the Korea National Health and Nutrition Examination Survey (2012-2018) and analyzed a sample of 12,104 wage workers. Unmet dental needs were defined as cases in which individuals did not receive dental care, despite their need for examination or treatment, within the last year. Long working hours were defined as exceeding 52 h per week, based on the standard working hours stipulated by the Labor Standards Act. A binomial model was applied to calculate the prevalence ratio through multivariate logistic regression analysis. RESULTS: The prevalence of unmet dental needs was observed in 3,948 cases (32.5%), among which 1,478 attributed their presence to lack of time. The prevalence of unmet dental needs showed an inverse relationship with the education level and household income. The wage workers who worked long hours had the highest prevalence of unmet dental needs. Long working hours were found to be 1.18 times (95% CI 1.07-1.29) more likely to result in unmet dental care compared to working less than 40 h. The relationship between long working hours and unmet dental needs were statistically significant only in men (PR 1.24, 95% CI 1.07-1.43). However, the relationship between long working hours and unmet dental needs owing to time were in both men and women (men: PR 1.59, 95% CI 1.20-2.11, women: PR 1.90, 95% CI 1.48-2.43). CONCLUSIONS: This study confirmed that long working hours and unmet dental needs are related when occupational factors are taken into consideration, despite the absence of oral health indicators. Using this study as a reference, further research is necessary to identify the underlying causes of unmet dental care and to improve access to dental services in the future.

[Correlation of patient satisfaction with nurses' time spent at the bedside: A prospective observational study]. / Zusammenhang der Patientenzufriedenheit mit der Anwesenheitszeit Pflegender am Patientenbett.

Correlation of patient satisfaction with nurses' time spent at the bedside: A prospective observational study Abstract. Background: Patient satisfaction is of high importance in quality assurance in many hospitals. The existing shortage of nursing staff and the resulting additional workload for individual nurses reduce the time available for patient care. Aim: The aim of this study is to explore a possible relationship of patient satisfaction with the time spent by nurses at the bedside and the influence of other influencing predictors. Methods: In this observational study, nursing attendance time was collected using attendance records which were verified by digital call light logs, and then evaluated using a linear regression model including patient satisfaction. Results: The nursing attendance time showed no significant influence on "patient satisfaction" (p = 0.155). The most important variables influencing "patient satisfaction" were: "no previous hospital experience" (p = 0.001), "importance of care" (p < 0.001) and "Gender" (form male) (p = 0.001). Conclusions: The time spent by nurses at the patient's bedside is not considered decisive enough to have a clear positive influence on patient satisfaction. Adaptations in nursing care are recommended, which enable a holistic relationship building and goal-oriented nursing care that favours patient satisfaction.

Relationship between time from symptom's onset to diagnosis and prognosis in patients with symptomatic colorectal cancer.

BACKGROUND: Controversy exists regarding the relationship of the outcome of patients with colorectal cancer (CRC) with the time from symptom onset to diagnosis. The aim of this study is to investigate this association, with the assumption that this relationship was nonlinear and with adjustment for multiple confounders, such as tumor grade, symptoms, or admission to an emergency department. METHODS: This multicenter study with prospective follow-up was performed in five regions of Spain from 2010 to 2012. Symptomatic cases of incident CRC from a previous study were examined. At the time of diagnosis, each patient was interviewed, and the associated hospital and clinical records were reviewed. During follow-up, the clinical records were reviewed again to assess survival. Cox survival analysis with a restricted cubic spline was used to model overall and CRC-specific survival, with adjustment for variables related to the patient, health service, and tumor. RESULTS: A total of 795 patients had symptomatic CRC and 769 of them had complete data on diagnostic delay and survival. Univariate analysis indicated a lower HR for death in patients who had diagnostic intervals less than 4.2 months. However, after adjustment for variables related to the patient, tumor, and utilized health service, there was no relationship of the diagnostic delay with survival of patients with colon and rectal cancer, colon cancer alone, or rectal cancer alone. Cubic spline analysis indicated an inverse association of the diagnostic delay with 5-year survival. However, this association was not statistically significant. CONCLUSIONS: Our results indicated that the duration of diagnostic delay had no significant effect on the outcome of patients with CRC. We suggest that the most important determinant of the duration of diagnostic delay is the biological profile of the tumor. However, it remains the responsibility of community health centers and authorities to minimize diagnostic delays in patients with CRC and to implement initiatives that improve early diagnosis and provide better outcomes.

Long-term reoperation risk after apical prolapse repair in female pelvic reconstructive surgery.

BACKGROUND: Although several different apical suspension procedures are available to women with pelvic organ prolapse, data on long-term efficacy and safety profiles are limited. OBJECTIVE: The primary aim of this study was to analyze longitudinal reoperation risk for recurrent prolapse among the 4 apical suspension procedures over 2 to 15 years. Secondary aims included evaluation of all-cause reoperation, defined as a repeated surgery for the indications of recurrent prolapse and adverse events, and total retreatment rate, which included a repeated treatment with another surgery or a pessary. STUDY DESIGN: This was a multicenter, retrospective cohort study within Kaiser Permanente Southern California that included women who underwent sacrocolpopexy, uterosacral ligament suspension, sacrospinous ligament fixation, or colpocleisis from January 2006 through December 2018. Women who underwent concomitant rectal prolapse repair or vaginal prolapse repair with mesh augmentation were excluded. Data were abstracted using procedural and diagnostic codes through July 2021, with manual review of 10% of each variable. Patient demographics and pessary use were compared using analysis of variance or chi square tests for continuous and categorical variables, respectively. Time-to-event analysis was used to contrast reoperation rates. A Cox regression model was used to perform an adjusted multivariate analysis of the following predictors of reoperation for recurrence: index surgery, concomitant procedures, patient demographics, baseline comorbidities, and year of index surgery. Censoring events included exit from the health maintenance organization and death. RESULTS: The cohort included 9681 women with maximum follow-up of 14.8 years. The overall incidence of reoperation for recurrent prolapse was 7.4 reoperations per 1000 patient-years, which differed significantly by type of apical suspension (P<.0001). The incidence of reoperation was lower after colpocleisis (1.4 events per 1000 patient-years) and sacrocolpopexy (4.8 events per 1000 patient-years) when compared with uterosacral ligament suspension (9 events per 1000 patient-years) and sacrospinous ligament fixation (13.9 events per 1000 patient-years). All pairwise comparisons between procedures were significant (P=.0003-.0018) after correction for multiplicity, except for uterosacral ligament suspension or uterosacral ligament hysteropexy vs sacrospinous ligament fixation or sacrospinous ligament hysteropexy (P=.05). The index procedure was the only significant predictor of reoperation for recurrence (P=.0003-.0024) on multivariate regression analysis. Reoperations for complications or sequelae (overall 2.9 events per 1000 patient-years) also differed by index procedure (P<.0001) and were highest after sacrocolpopexy (4.4 events per 1000 patient-years). The incidence of all-cause reoperation for recurrence and adverse events after sacrocolpopexy, however, was comparable to that of the other reconstructive procedures (P=.1-.4) in pairwise comparisons with Bonferroni correction. Similarly, frequency of pessary use differed by index procedure (P<.0001) and was highest after sacrospinous ligament fixation at 9.3% (43/464). CONCLUSION: Among nearly 10,000 patients undergoing prolapse surgery within a large managed care organization, colpocleisis and sacrocolpopexy offered the most durable obliterative and reconstructive prolapse repairs, respectively. All-cause reoperation rates were lowest after colpocleisis by a large margin, but similar among reconstructive apical suspension procedures.
