Evaluating the role of heart rate variability in monitoring stress and sleep quality among nurses in the aftermath of the COVID-19 pandemic.

AIM: To assess heart rate variability (HRV) as a measure to assess job stress and sleep quality among nurses in the post-COVID-19 period. BACKGROUND: The COVID-19 pandemic significantly affected nurses, with heightened job stress and impaired sleep quality impacting their well-being and effectiveness in patient care. HRV could offer insights for supporting strategies in the pandemic aftermath. DESIGN: A quantitative cross-sectional study. METHODS: This study involved 403 clinical nurses recruited from a teaching hospital in Taiwan. Data on job stress, work frustration, sleep quality and HRV were collected and analysed. RESULTS: Among the nurses surveyed during the COVID-19 pandemic, 72.7% reported poor sleep quality (PSQI = 9.369). Job stress emerged as a strong predictor of work frustration. High stress levels and poor sleep quality were correlated with significantly decreased HRV, indicating a potential physiological impact of stress on the nurses' health and well-being. CONCLUSIONS: HRV is a valuable and cost-effective measure for monitoring and managing nurses' well-being in the post-COVID-19 era. Targeted interventions can be implemented to support nurses' overall performance and promote their well-being by identifying those at high risk of job stress and poor sleep quality.

Nurses' perceived health and occupational burnout: A focus on sleep quality, workplace violence, and organizational culture.

AIM: This study investigates the mediation of sleep quality between perceived health and occupational burnout in hospital nurses, considering the moderation of workplace violence and organizational culture. BACKGROUND: Occupational factors lead to physical and mental distress, burnout, and sleep issues in nurses. Approximately two-thirds of nurses experience burnout, impacting patient care quality and safety. Cultivating a positive organizational culture is essential for nursing workforce stability. METHODS: This cross-sectional study employed convenience sampling to recruit 346 nurses from a teaching hospital in southern Taiwan in July-August 2020 (response rate: 87.3%). Self-administered questionnaires containing validated instruments were employed, including an adapted occupational burnout scale, the Chinese version of an organizational culture scale, a Perceived Health Questionnaire, a Workplace Violence Experience Scale, and the CPSQI; all instruments were reliable and valid. The analysis involved descriptive statistics, linear regression, and the Johnson-Neyman technique. RESULTS: Nurses with better perceived health exhibited significantly lower occupational burnout (p < 0.001). Perceived health indirectly impacted burnout through sleep quality (p < 0.01) with organizational culture as a partial moderator. Bureaucratic organizational culture exacerbated this relationship. Additionally, decreased workplace violence moderated the connections among perceived health, sleep quality, and occupational burnout among nurses. CONCLUSIONS: Given the inverse correlation between nurses' perceived health and occupational burnout and considering factors such as workplace violence, organizational culture, and sleep quality, healthcare institutions can proactively take steps to enhance nurses' overall well-being and mitigate burnout. IMPLICATIONS FOR NURSING AND HEALTH POLICY: By implementing wellness programs, mental health support, security training, robust reporting, and a zero-tolerance approach to violence, healthcare stakeholders can foster a safe and supportive work environment for nurses, thus improving well-being, patient outcomes, and healthcare quality.

O → S Acyl Transfer Directing Human Sera Glycoprotein Immobilization for Breast Cancer Diagnosis.

Breast cancer (BC) is one of the most common malignancies in the world with aberrantly expressed glycans. The different types and stages still limit a comprehensive method in the prediagnosis of BC patients. In this research, a synthetic boronic acid-disulfide (BASS) probe has been developed for the two steps of O → S → N acyl transfer in glycoprotein recognition and labeling. The specificity and sensitivity of this method have been carefully studied in the case of immunoglobulin G, and the labeling efficiency was determined up to 60%. The BASS-functionalized slide is a powerful platform for monitoring the alteration of glycan patterns in human sera. Compared to the samples from healthy individuals, sera of BC patients gave specific patterns to eight lectins binding. The BASS-directed glycoprotein strategy promises a rapid sensing platform for a high-throughput screening of clinical BC samples and could be easily applied to other cancer prediagnoses.

Ibrutinib for First-Line Treatment of Chronic Graft-Versus-Host Disease: Results From the Randomized Phase III iNTEGRATE Study.

PURPOSE: To present primary and final analyses from the randomized, double-blind, placebo-controlled, phase III iNTEGRATE study, which evaluated the safety and efficacy of ibrutinib with prednisone in previously untreated patients with chronic graft-versus-host disease (cGVHD). METHODS: Patients (age ≥ 12 years) with newly diagnosed moderate or severe cGVHD, requiring systemic corticosteroid therapy, and with no prior systemic treatment for cGVHD were randomly assigned 1:1 to receive ibrutinib 420 mg once daily plus prednisone, starting at 1 mg/kg once daily or placebo plus prednisone. The primary end point was response rate at 48 weeks according to 2014 National Institutes of Health Consensus Development Project Criteria. Other end points included event-free survival, duration of response, time to withdrawal of immunosuppressants, improvement in Lee cGVHD Symptom Scale score, overall survival (OS), and safety. RESULTS: Ninety-five and 98 patients enrolled in the ibrutinib-prednisone and placebo-prednisone arms, respectively. At 48 weeks, response rates were 41% (ibrutinib-prednisone) and 37% (placebo-prednisone; P = .54). At 33 months of follow-up, median duration of response was 19 months (ibrutinib-prednisone) and 10 months (placebo-prednisone; P = .10). Median event-free survival was 15 months (ibrutinib-prednisone) and 8 months (placebo-prednisone; hazard ratio, 0.76; 95% CI, 0.54 to 1.1; P = .11). Improvement in overall Lee cGVHD Symptom Scale was 43% (ibrutinib-prednisone) and 31% (placebo-ibrutinib; P = .07). Median OS was not reached in either arm. The 24-month Kaplan-Meier OS estimates were 80% for both arms (hazard ratio, 1.06; 95% CI, 0.59 to 1.90). Grade ≥ 3 serious adverse events occurred in 49% (ibrutinib-prednisone) and 47% (placebo-prednisone) of patients. CONCLUSION: There was no statistical difference observed in the primary and secondary end points with ibrutinib-prednisone treatment. No new safety signals were observed with ibrutinib treatment in previously untreated patients with cGVHD. The primary end point of iNTEGRATE was not met.

Heart rate variability as an indicator of the beneficial effects of Qigong and mindfulness training on the mind-body well-being of cancer survivors.

BACKGROUND: Cancer-related fatigue (CRF) and fear of recurrence (FOR) are frequently experienced by cancer patients. This study aimed to improve cancer survivors' CRF, FOR, quality of life (QOL), and heart rate variability (HRV) through Qigong and mindfulness interventions. METHODS: A quasi-experimental design was adopted, and 125 cancer survivors were recruited using snowball sampling. The participants were assigned to 1 of 3 groups (Qigong, mindfulness, and control) based on their needs and preferences. All groups received 4 h of nutrition education at the pretest (T0). CRF, FOR, and QOL questionnaires and HRV parameters were used as the measurement tools. Data were collected at the pretest (T0), posttest (T1), and follow-up (T2). RESULTS: Qigong had a better effect on improving CRF (ΔT1-T0 = - 0.108, ΔT2-T1 = - 0.008) and FOR (ΔT1-T0 = - 0.069, ΔT2-T1 = - 0.150) in the long term, while mindfulness improved QOL (ΔT1-T0 = 0.096, ΔT2-T1 = 0.013) better in the long term. Both Qigong and mindfulness had a short-term effect in improving SDNN (Q: ΔT1-T0 = 1.584; M: ΔT1-T0 = 6.979) and TP (Q: ΔT1-T0 = 41.601; M: ΔT1-T0 = 205.407), but the improvement in LF (Q: ΔT2-T1 = - 20.110; M: ΔT2-T1 = - 47.800) was better in the long term. CONCLUSION: HRV evaluation showed that Qigong and the mindfulness interventions had short-term effects in significantly improving overall physical and mental health, self-emotional regulation, and QOL and relieving fatigue and autonomic dysfunction. HRV may serve as an observational indicator of interventions to improve physical and mental health. The consistent practice of mind-body interventions is the primary means of optimizing overall health and well-being.

Ibrutinib Treatment of Pediatric Chronic Graft-versus-Host Disease: Primary Results from the Phase 1/2 iMAGINE Study.

Chronic graft-versus-host disease (cGVHD) is a potentially life-threatening complication of allogeneic hematopoietic stem cell transplantation. Clinical data surrounding cGVHD therapies in younger children are limited and critically needed. Primary endpoints were to determine the recommended pediatric equivalent dose (RPED) and assess pharmacokinetics (PK) and safety. Secondary endpoints included overall response rate (ORR; comprising complete response and partial response) according to the 2014 National Institutes of Health criteria at 24 weeks, overall survival, and duration of response (DOR). Here we present the primary results from the open-label, multicenter, international phase 1/2 iMAGINE study (PCYC-1146-IM), which evaluated the PK, safety, and efficacy of ibrutinib in patients age ≥1 to <22 years with treatment-naive (TN) or relapsed/refractory (R/R) moderate/severe cGVHD. Patients age <12 years received once-daily ibrutinib starting at 120 mg/m2 and escalating to 240 mg/m2 (full adult dose equivalent) after 14 days if free from ibrutinib-related grade ≥3 toxicity; patients age ≥12 years received once-daily ibrutinib 420 mg. Fifty-nine patients (12 TN and 47 with R/R cGVHD; median age, 13 years; range, 1 to 19 years) were enrolled. Plasma concentration-time profiles for ibrutinib 240 mg/m2 (the RPED) were comparable to those observed in adults with cGVHD at a dose of 420 mg/day. Safety was consistent with the known profile of ibrutinib in cGVHD. ORR by 24 weeks was 64% (38 of 59), including 83% (10 of 12) for the TN subgroup and 60% (28 of 47) for R/R. Among 46 responders (median follow-up, 20 months; range, 2 to 32 months), 12-month DOR for each subgroup was 60% (95% confidence interval [CI], 25% to 83%) in TN patients and 58% (95% CI, 35% to 75%) in R/R patients. Responses were durable, with numerically higher rates than those previously observed with ibrutinib in adults, demonstrating that ibrutinib provides clinically meaningful activity with acceptable safety in children with moderate/severe cGVHD.

Mindfulness Stress Management for Female Cancer Survivors Facing the Uncertainty of Disease Progression: A Randomized Controlled Study.

This study aimed to determine the effect of a mindfulness stress management intervention on fear of recurrence and quality of life among female cancer survivors. A longitudinal, randomized design with two groups (60 participants) was used for pretest/posttest comparisons. Twelve weeks of mindfulness stress intervention effectively attenuated fear of recurrence symptoms (T1 p = 0.002, T2 p = 0.047), and quality of life (T1 p = 0.000, T2 p = 0.001) significantly increased. The results were significantly different between the intervention and control groups. Over time, group differences became more significant (T1 p = 0.002), demonstrating the effectiveness of the mindfulness stress management intervention. When female cancer survivors face uncertain disease progression, fear of recurrence affects their quality of life. When these women receive supportive intervention sooner, their improvement is more significant. Healthcare providers should encourage female cancer survivors to engage in mindfulness stress management actions to achieve a better benefit.

Exploring the relationships among training needs, willingness to participate and job satisfaction in disaster nursing: The mediating effect of achievement motivation.

OBJECTIVES: Disaster nursing competencies and their willingness to participate are essential for the success of disaster relief nurses. This study investigates the correlations among emergency room and intensive care unit nurses' training needs, willingness to participate, achievement motivation and job satisfaction as well as their mutual influences on disaster relief efforts. METHODS: A convenience sampling cross-sectional study was conducted, where 488 emergency room and intensive care unit nurses from five hospitals in Taiwan participated (response rate: 84.4%). The relationships among the variables were verified using structural equation modelling. RESULTS: Training needs in disaster nursing were found to be positively correlated with willingness to participate and job satisfaction. Moreover, willingness to participate was found to be positively correlated with achievement motivation and job satisfaction. Achievement motivation was found to be positively correlated with job satisfaction. Furthermore, willingness to participate in disaster relief was found to indirectly mediate job satisfaction through achievement motivation. CONCLUSIONS: The fulfilment of training needs for disaster nursing and willingness to participate may have an impact on nurses' job satisfaction through the mediating effect of achievement motivation. Nurses' learning needs should be the foremost consideration in disaster nursing training to alleviate human resource shortages and improve disaster responses. These findings can serve as a reference for increasing preparedness training for nurses in disaster management. RELEVANCE TO CLINICAL PRACTICE: Nurses substantially contribute to the progression of disaster relief and postdisaster reconstruction. Successful and effective disaster management relies on sufficient nurse responses and training preparedness. Nurses' willingness to participate and achievement motivation in disaster nursing can have an impact on their job satisfaction and alleviate distress for both themselves and patients for the purpose of disaster relief.

Effects of multimedia-based fall prevention education on the knowledge, attitudes, or behaviors of patients.

OBJECTIVES: Patient safety is regarded as a critical quality monitoring indicator for medical institutions. The effects of a multimedia-based patient education intervention on knowledge, attitudes, and behaviors regarding fall prevention were observed. METHODS: The study had a quasi-experimental research design and enrolled 140 participants. Seventy participants in the experimental group received multimedia-based patient education and a health education leaflet, while those in the control group received only the health education leaflet. A structured questionnaire was used for data collection at baseline, and a posttest was applied after the intervention. RESULTS: The participants were predominantly treated in the gastroenterology department (45.7%), followed by the pulmonology department (33.6%). A total of 86.4% of patients had not experienced a fall within 3 months. After the intervention, the average scores for all variables in the experimental group were higher than those in the control group. The results indicate that attitudes, knowledge, and behaviors regarding fall prevention among patients in the pulmonology department were higher than those among patients in the gastroenterology department; the differences were statistically significant. CONCLUSION: The individualized health education content was of substantial significance for patients with different disease backgrounds and facilitated changes in their knowledge, attitudes, and behaviors regarding falls. RELEVANCE TO CLINICAL PRACTICE: Multimedia-based patient education influenced inpatients' knowledge, attitudes, and behaviors for preventing falls.

The mediating and moderating effects of shared decision making and medical autonomy on improving medical service satisfaction in emergency observation units.

OBJECTIVE: Distinct from other medical settings, the emergency setting is unique and requires flexible and adaptive decision making to provide quality medical services. This study was designed to investigate the mediating and moderating effects of shared decision making (SDM) and patient attitude toward medical autonomy (AMA) on improving medical service satisfaction (MSS) in emergency observation units. METHODS: In this cross-sectional study, we collected data via a verified structured questionnaire. A total of 165 participants met the inclusion criteria, and 100% of the questionnaires recovered were valid. RESULTS: The results show that SDM had a partial mediating effect (p < 0.01) and that it significantly improved MSS. AMA had a moderating effect on some domains (p < 0.01). Meeting patient needs and increasing their participation in decision making can effectively improve MSS. However, excessive patient participation might not be productive, which is an important finding of this study. CONCLUSION: In emergency observation units, SDM-based doctor-patient interactions and cooperation, effective patient-centered communication, and respect for patients' medical autonomy improve the doctor-patient relationship and patients' health literacy. Patients can thus participate in selecting the best treatment plan to achieve expected health outcomes, and ultimately improve MSS.

Concurrent ibrutinib plus venetoclax in relapsed/refractory mantle cell lymphoma: the safety run-in of the phase 3 SYMPATICO study.

Ibrutinib plus venetoclax, given with an ibrutinib lead-in, has shown encouraging clinical activity in early phase studies in mantle cell lymphoma (MCL). The ongoing phase 3 SYMPATICO study evaluates the safety and efficacy of concurrently administered, once-daily, all-oral ibrutinib plus venetoclax in patients with relapsed/refractory MCL. A safety run-in (SRI) cohort was conducted to inform whether an ibrutinib lead-in should be implemented for the randomized portion. Patients received concurrent ibrutinib 560 mg continuously plus venetoclax in a 5-week ramp-up to venetoclax 400 mg for up to 2 years. The primary endpoint was occurrence of tumor lysis syndrome (TLS) and dose-limiting toxicities (DLTs). The SRI cohort enrolled 21 patients; six and 15 were in low- or increased-risk categories for TLS, respectively. During the 5-week venetoclax ramp-up, three patients had DLTs, and one patient at increased risk for TLS had a laboratory TLS; no additional TLS events occurred during follow-up. With a median follow-up of 31 months, the overall response rate was 81% (17/21); 62% (13/21) of patients had a complete response. SRI data informed that the randomized portion should proceed with concurrent ibrutinib plus venetoclax, with no ibrutinib lead-in. Ibrutinib plus venetoclax demonstrated promising efficacy; no new safety signals were observed.Trial registration: ClinicalTrials.gov, NCT03112174. Registered 13 April 2017, https://clinicaltrials.gov/ct2/show/NCT03112174 .

The Biomechanical Characterization of the Turning Phase during a 180° Change of Direction.

The aim of this study was to characterize the turning phase during a modified 505 test. Forty collegiate basketball students, divided into faster and slower performers and high-playing-level and low-playing-level groups, were evaluated for the force-time characteristics (braking and/or propulsive phase) of the penultimate foot contact (PFC), final foot contact (FFC), and first accelerating foot contact (AFC), and for completion time and approach velocity. Based on the composition of the AFC, trials were classified as braking/propulsive or only propulsive. Regression analysis for the prediction of completion time was performed. The AFC contributed to reacceleration through shorter contact times and step length, and lower braking force production (p < 0.05). Faster performers and the high-playing-level group demonstrated (p < 0.05): lower completion times, higher approach velocities, longer steps length in the PFC and FFC, greater braking forces and impulses in the PFC; greater braking and propulsive forces, braking impulses, lower contact times in the FFC; greater braking and propulsive horizontal forces, horizontal impulses, lower contact times and vertical impulses in the AFC. Kinetic variables from only the FFC and AFC and approach velocity predicted 75% (braking/propulsive trials) and 76.2% (only-propulsive trials) of completion times. The characterization of the turning phase demonstrated the specific contribution of each foot contact and the possible implications for training prescription.

Improved urinary melatonin level as the perspective indicator that leads to better sleeping quality in bladder cancer patients.

BACKGROUND: Individuals with higher-than-average melatonin concentrations are less likely to develop cancer. In cancer patients, psychosomatic coping patterns and treatment side effects are important indicators of cancer prevention and immune system deterioration. This study focused on changes in the urinary melatonin concentration, life resilience, and sleep quality in bladder cancer patients before, and 3 months after, treatment. METHODS: A controlled before-and-after study was performed. The subjects were patients who were previously diagnosed with bladder cancer and had received treatment (transurethral resection of bladder tumor + intravesical chemotherapy). Data from 23 subjects were analyzed. RESULTS: The results showed a significant difference in the melatonin concentration before and after treatment (Wilcoxon signed-rank test, Z = -2.220, p = 0.026). The melatonin concentration in 16 patients (70%) increased after treatment. The mean Pittsburgh Sleep Quality Index (PSQI) score before treatment was 7.348 (SD = 4.030), which was associated with poor sleep quality. The mean PSQI score after treatment was 6.435 (SD = 3.300; Z = -2.071; p = 0.038). These results represent the improved sleep quality in patients post-treatment. CONCLUSIONS: After treatment, the urinary melatonin concentration and sleep quality (PSQI) improved, both of which were statistically significant in bladder cancer patients. Consequently, bladder cancer treatment should be initiated as soon as possible. There was no significant difference in overall life resilience before and after treatment, possibly because elderly individuals have strong personality traits and emotional stability and are not easily affected by life events or stress.

Final analysis of a phase 1/2b study of ibrutinib combined with carfilzomib/dexamethasone in patients with relapsed/refractory multiple myeloma.

Patients with multiple myeloma (MM) inevitably relapse on initial treatment regimens, and novel combination therapies are needed. Ibrutinib is a first-in-class, once-daily inhibitor of Bruton's tyrosine kinase, an enzyme implicated in growth and survival of MM cells. Preclinical data suggest supra-additivity or synergy between ibrutinib and proteasome inhibitors (PIs) against MM. This phase 1/2b study evaluated the efficacy and safety of ibrutinib plus the PI carfilzomib and dexamethasone in patients with relapsed/refractory MM (RRMM). In this final analysis, we report results in patients who received the recommended phase 2 dose (RP2D; ibrutinib 840 mg and carfilzomib 36 mg/m2 with dexamethasone), which was determined in phase 1. The primary efficacy endpoint was overall response rate (ORR). Fifty-nine patients with RRMM received the RP2D (18 in phase 1 and 41 in phase 2b). These patients had received a median of three prior lines of therapy; 69% were refractory to bortezomib, and 90% were refractory to their last treatment. ORR in the RP2D population was 71% (stringent complete response and complete response: 3% each). Median duration of clinical benefit and median duration of response were both 6.5 months. Median progression-free survival (PFS) was 7.4 months, and median overall survival (OS) was 35.9 months. High-risk patients had comparable ORR and median PFS (67% and 7.7 months, respectively) to non-high-risk patients, whose ORR was 73% and median PFS was 6.9 months, whereas median OS in high-risk patients was 13.9 months and not reached in non-high-risk patients. The most common grade ≥3 hematologic treatment-emergent adverse events (TEAEs) were anemia and thrombocytopenia (17% each); the most common grade ≥3 non-hematologic TEAE was hypertension (19%). In patients with RRMM treated with multiple previous lines of therapy, ibrutinib plus carfilzomib demonstrated anticancer activity within the expected efficacy range. No new safety signals were identified and the combination was well-tolerated.

Validity and Reliability of a Photoelectric Cells System for the Evaluation of Change of Direction and Lateral Jumping Abilities in Collegiate Basketball Athletes.

The validity and reliability of the Optojump system were investigated for jumping height and flight time in vertical jump tests. Conversely, the purpose of the present study was to investigate the validity and reliability of the Optojump system for measuring contact time and lateral displacement in change of direction and lateral jump tests. Thirty basketball collegiate athletes were tested on two 10 m sprints with a 60° (COD60) or 180° (COD180) change of direction, lateral controlled (CLRJ) and maximal (MLRJ) rebound jump, and lateral countermovement (LCMJ) and squat (LSJ) jump with the concomitant use of two force plates and the Optojump system for the measurement of contact time in COD60, COD180, CLRJ, MLRJ, and lateral jumping distance in all the lateral jump tests. Almost perfect coefficients (r ≥ 0.95) emerged for contact time in COD60, COD180, CLRJ, MLRJ, although a systematic bias was found for COD60 (-0.01 s). Good-to-excellent reliability was found for almost all the measurements of contact time and lateral jumping distance for change of direction and lateral jump tests. Therefore, the use of Optojump system for testing change of direction and lateral jumping abilities should be executed with caution, avoiding misinterpretation of data.

Acute Effects of Battle Rope Exercise on Performance, Blood Lactate Levels, Perceived Exertion, and Muscle Soreness in Collegiate Basketball Players.

Chen, WH, Yang, WW, Lee, YH, Wu, HJ, Huang, CF, and Liu, C. Acute effects of battle rope exercise on performance, blood lactate levels, perceived exertion, and muscle soreness in collegiate basketball players. J Strength Cond Res 34(10): 2857-2866, 2020-This study investigated the acute effects of battle rope (BR) exercise on basketball players' performance, blood lactate levels, rating of perceived exertion (RPE), and perceived muscle soreness. Fifteen well-trained Division-I male basketball players underwent the same test procedure at baseline, before BR exercise (30 minutes of rest after the baseline test), and after BR exercise. The 30-minute experimental protocol comprised 6 BR exercises at a work-to-rest ratio of 1:2 (20-second exercise and 40-second rest). Shooting accuracy, basketball chest pass speed, countermovement jump (CMJ) height, blood lactate levels, RPE (Borg Category-Ratio-10 scale), and perceived muscle soreness (visual analog scale, 0-100 mm) were measured in each test. The results indicated no change for any variables between baseline and before BR exercise. After BR exercise, performance decrements (p < 0.05) were recorded in shooting accuracy (16.9%) and basketball chest pass speed (9.1%), but no significant changes were observed for CMJ height. Battle rope exercise caused increases in blood lactate levels (13.6 mmol·L), RPE (9.9), and perceived muscle soreness (upper-limb: 63-67 mm; trunk: 43-68 mm; and lower-limb: 45-52 mm). In conclusion, BR exercise is physically demanding on the upper body, resulting in decreased performance in shooting accuracy and basketball chest pass speed. Battle rope exercise may not be beneficial before a practice or game because it triggers acute exercise-induced performance decrements and fatigue. However, BR exercise may be suitable for basketball training sessions in which the objective is to strengthen technical skills under fatiguing conditions.

The Health Promoting Mindfulness or Qigong Educational Programs for Beneficial Lifestyle Changes of Cancer Survivors.

This study used heart rate variability (HRV) to monitor levels of cancer-related fatigue (CRF) and quality of life (QOL) of cancer survivors subjected to program measures at different psychosomatic or functional levels. A longitudinal study was conducted at a cancer center in Taiwan. Fifty-two cancer survivals were randomly assigned to either the mindfulness group (n = 25) or the Qigong group (n = 27). Both groups received a 12-week mindfulness and Qigong programs, respectively. Improvements in CRF, QOL, and HRV after a 12-week program and at the 3-month follow-up point. For the long-term effects in both mindfulness and Qigong groups, CRF showed a significant downward trend (p < 0.05), but a significant upward trend was observed in HRV (p < 0.001). Mindfulness and Qigong exhibited different effectiveness in individuals, indicating that the mental and physical aspects of health are equally essential and should be addressed in a complementary combination. These findings are worthy of being shared with cancer survivors to benefit their physical and mental well-being. We suggest that healthcare professionals incorporate mindfulness and Qigong in cancer survivors' daily life as means to encourage lifestyle changes for improving their health.

A phase 2 study of ibrutinib in combination with bortezomib and dexamethasone in patients with relapsed/refractory multiple myeloma.

OBJECTIVE: We evaluated ibrutinib, a once-daily inhibitor of Bruton's tyrosine kinase, combined with bortezomib and dexamethasone in patients with relapsed or relapsed/refractory multiple myeloma who had received 1-3 prior therapies. METHODS: This was a phase 2, single-arm, open-label, multicentre study (NCT02902965). The primary endpoint was progression-free survival (PFS). RESULTS: Seventy-six patients were enrolled; 74 received ≥1 dose of study treatment. After median follow-up of 19.6 months, median PFS was 8.5 months (95% CI: 6.2-10.8); median overall survival was not reached. Overall response rate was 57% (95% CI: 45-68), and median duration of response was 9.5 months (95% CI: 6.9-10.6). Grade 3/4 AEs occurred in 73% of patients and fatal AEs occurred in 15% of patients. Incidence of major haemorrhage was 5%; one patient died from cerebral haemorrhage. After an observed increased incidence of serious (42%) and fatal (11%) infections, enrolment was suspended to implement risk-minimisation measures. The safety profile was otherwise consistent with known safety profiles of the individual drugs. CONCLUSION: Ibrutinib combined with bortezomib and dexamethasone elicited clinical responses. However, efficacy assessments conducted at potential restart of enrolment indicated that the targeted PFS could not be reached with additional patient enrolment, and the study was terminated.

Effects of education and support groups organized by IBCLCs in early postpartum on breastfeeding.

OBJECTIVE: To examine the effectiveness of breastfeeding education and peer support groups organized by International Board Certified Lactation Consultants (IBCLCs) during the first week (T1) and the fifth to sixth week postpartum (T2), in terms of breastfeeding self-efficacy and exclusive breastfeeding rate. DESIGN: A quasi-experimental design. SETTING: A maternity ward of a medical center in northern Taiwan. PARTICIPANTS: 214 postpartum women. INTERVENTION: The control group (n = 122) received standard care, while the intervention group (n = 92) received standard care and attended a support group at T1 and T2. MEASUREMENTS: Outcome measures were assessed through self-administered questionnaires: Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) and exclusive breastfeeding rate. Demographic and obstetric data were collected from participants and from their medical records. A general estimating equation, t-tests, and chi-square tests were adopted to examine hypotheses. FINDINGS: Before examining the hypotheses, homogeneous tests confirmed the equality between the groups at T1. There were significant differences in breastfeeding self-efficacy (B = 0.21, p < 0.01) between the two groups from T1 to T2. The breastfeeding self-efficacy of participants in the intervention group was significantly higher than those in the control group (t = 3.26, p = 0.01) at T2. The exclusive breastfeeding rate (61%) in the intervention group at T2 was significantly higher than the rate (39%) in the control group (chi-square=11.28, p = 0.001). KEY CONCLUSIONS: Attending IBCLC-organized breastfeeding education and support groups during early postpartum hospitalization may increase mothers' breastfeeding self-efficacy and exclusive breastfeeding rate.

Promyelocytic leukemia zinc finger is involved in the formation of deep layer cortical neurons.

BACKGROUND: Promyelocytic leukemia zinc finger (Plzf), a transcriptional regulator involved in a lot of important biological processes during development, has been implied to maintain neural stem cells and inhibit their differentiation into neurons. However, the effects of Plzf on brain structures and functions are still not clarified. RESULTS: We showed that Plzf expression was detected as early as embryonic day (E) 9.5 in Pax6+ cells in the mouse brain, and was completely disappeared in telencephalon before the initiation of cortical neurogenesis. Loss of Plzf resulted in a smaller cerebral cortex with a decrease in the number of Tbr1+ deep layer neurons due to a decrease of mitotic cell number in the ventricular zone of forebrain at early developmental stage. Microarray, qRT-PCR, and flow cytometry analysis identified dysregulation of Mash1 proneural gene expression. We also observed an impairment of recognition memory in Plzf-deficient mice. CONCLUSIONS: Plzf is expressed at early stages of brain development and involved in the formation of deep layer cortical neurons. Loss of Plzf results in dysregulation of Mash1, microcephaly with reduced numbers of early-born neurons, and impairment of recognition memory.
