Background: Noninvasive neurally-adjusted ventilatory assist (NIV-NAVA) improves patient-ventilator synchrony and may reduce treatment failure in preterm infants compared with nasal continuous positive airway pressure (NCPAP) and noninvasive positive-pressure ventilation (NIPPV). We conducted a systematic review and meta-analysis to assess the effects of NIV-NAVA in preterm infants with respiratory distress. Methods: Four investigators independently assessed the eligibility of studies in CENTRAL, CINAHL, ClinicalTrials.gov, Embase, MEDLINE, PubMed, and WHO ICTRP databases, and extracted data. The included studies were randomized controlled trials (RCTs) comparing NIV-NAVA with other noninvasive ventilation modalities in preterm infants. The certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation approach. The objective of the meta-analysis was to compare NIV-NAVA vs CPAP/NIPPV as a primary mode post extubation. Results: Five RCTs which examined 279 preterm infants were included. In the subgroup of post-extubation respiratory support, NIV-NAVA decreased treatment failure compared with NCPAP/NIPPV (risk ratio 0.29; 95% confidence interval [0.10, 0.81], 2 RCTs, 96 infants, low certainty of the evidence). NIV-NAVA did not significantly reduce the risk of treatment failure in the subgroup of primary respiratory support (very low certainty of the evidence). There were no significant differences in secondary outcomes with low to very low certainty of evidence. Conclusions: In a small cohort with low certainty of evidence, NIV-NAVA may prevent reintubation in preterm infants. Further large-scale RCTs are needed to determine the effects and safety of NIV-NAVA in preterm infants. [ABSTRACT FROM AUTHOR]

Aim: A summary of studies focusing on the mental health of midwives during the COVID‐19 pandemic has not yet been conducted. This review aims to comprehensively understand the current state of midwives' mental health in the context of the COVID‐19 pandemic and to provide valuable insights to guide future research. Methods: This study was based on a framework for conducting scoping reviews. The protocol was registered before conducting this review and procedures were carried out according to that protocol. Article searches were conducted in four databases from December 2019 to December 2023. From 921 articles selected according to pre‐registered protocol criteria, the analysis finally included 14 studies. Results: A total of 13 studies were cross‐sectional and one was longitudinal, with pre‐pandemic data. More than 80% of the studies began data collection within approximately 1 year after the pandemic was declared by the World Health Organization (by February 2021). Half of the studies were conducted in Asia. Burnout and turnover intentions were investigated in several studies but used different measures. Only two studies were aimed at positive aspects such as job satisfaction and well‐being. Conclusions: Most research on midwives' mental health during the COVID‐19 pandemic has focused on negative aspects such as burnout and turnover intentions. However, most results were cross‐sectional, with studies in the early stages of the pandemic, so continued follow‐up is needed. [ABSTRACT FROM AUTHOR]

Background In immunocompromised individuals, trimethoprim/sulfamethoxazole (TMP/SMX) for Pneumocystis pneumonia (PCP) prophylaxis has adverse events, and the optimal dosage is unclear. The objective of this study was to assess efficacy and safety of intermittent versus daily TMP/SMX for PCP prophylaxis. Methods This systematic review included randomized controlled trials (RCTs) indexed in the Cochrane Central Register of Controlled Trials, PubMed, Ichushi, or Embase databases, published from database inception to September 2023. The inclusion criteria were adults taking intermittent or daily TMP/SMX for PCP prophylaxis. Risk of bias was assessed using the Cochrane risk-of-bias tool. The primary outcomes were PCP incidence, PCP-related mortality, and adverse events requiring temporary or permanent TMP/SMX discontinuation. Results Four RCTs (N = 2808 patients) were included. PCP incidence did not differ significantly between the intermittent and daily regimen groups (risk ratio [RR], 1.17 [95% confidence interval {CI},.89–1.53]; certainty: very low). There was no PCP-related mortality in the 3 RCTs reporting its outcome. Compared with the daily regimen group, the intermittent regimen group experienced significantly fewer adverse events requiring temporary or permanent TMP/SMX discontinuation (RR, 0.51 [95% CI,.42–.61]; certainty: low) Conclusions This systematic review and meta-analysis suggests that intermittent TMP/SMX regimens for PCP prophylaxis may be more tolerable than daily regimens and may have similar efficacy. Further RCTs are needed to apply this to current practice. Clinical Trials Registration. PROSPERO (CRD42022359102). [ABSTRACT FROM AUTHOR]

Aim: We conducted a meta‐analysis comparing the invasiveness of automatic lancet devices, which can collect adequate amount of blood at shallow puncture depths, with conventional manual lance devices (lancet or needle) to statistically identify less invasive instruments for neonatal heel lance. Methods: We searched PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, and Ichushi databases for studies comparing the invasiveness between automatic lancet and manual lancet or needle in term and preterm neonates in neonatal intensive care unit. Results: This review included 9 out of 449 searched articles, with 673 neonates. Automatic lancet had significantly lower pain scores (standardised mean difference: −2.0, 95% confidence interval: −3.3 to −0.7), heart rate (mean difference: −8.0, 95% confidence interval: −13.8 to −2.1), cry duration (mean difference: −21.5, 95% confidence interval: −32.5 to −10.4), number of punctures (mean difference: −0.6, 95% confidence interval: −1.1 to −0.2), and duration of procedures (mean difference: −37.7, 95% confidence interval: −75.2 to −0.2) than manual lancet or needle. Furthermore, peripheral oxygen saturation was significantly higher in automatic lancet than in manual lancet or needle (mean difference: 4.5, 95% confidence interval: 0.5–8.5). Conclusion: Automatic heel lancet devices were less invasive than manual heel lance devices (lancet or needle). [ABSTRACT FROM AUTHOR]

Simple Summary: Febrile neutropenia is associated with high mortality, and the administration of anti-pseudomonal agents is required. Traditionally, combination therapy with aminoglycosides was weakly recommended in the guidelines, but recently, with the emergence of resistant bacteria, there has been increasing hope for combination antimicrobial therapy. The purpose of this systematic review, based on RCTs published up to 2023, is to examine how much more effective combination therapy with beta-lactams and aminoglycosides is compared to monotherapy with beta-lactams. We performed a systematic review of studies that compared beta-lactams vs. beta-lactams plus aminoglycosides for the treatment of febrile neutropenia in cancer patients. Method: We searched CENTRAL, MEDLINE, and Embase for studies published up to October 2023, and randomized controlled trials (RCTs) that compared anti-Pseudomonas aeruginosa beta-lactam monotherapy with any combination of an anti-Pseudomonas aeruginosa beta-lactam and an aminoglycoside were included. Result: The all-cause mortality rate of combination therapy showed no significant differences compared with that of monotherapy (RR 0.99, 95% CI 0.84 to 1.16, high certainty of evidence). Infection-related mortality rates showed that combination therapy had a small positive impact compared with the intervention with monotherapy (RR 0.83, 95% CI 0.66 to 1.05, high certainty of evidence). Regarding treatment failure, combination therapy showed no significant differences compared with monotherapy (RR 0.99, 95% CI 0.94 to 1.03, low certainty of evidence). In the sensitivity analysis, the treatment failure data published between 2010 and 2019 showed better outcomes in the same beta-lactam group (RR 1.10 [95% CI, 1.01–1.19]). Renal failure was more frequent with combination therapy of any daily dosing regimen (RR 0.46, 95% CI 0.36 to 0.60, high certainty of evidence). Conclusion: We found combining aminoglycosides with a narrow-spectrum beta-lactam did not spare the use of broad-spectrum antibiotics. Few studies included antibiotic-resistant bacteria and a detailed investigation of aminoglycoside serum levels, and studies that combined the same beta-lactams showed only a minimal impact with the combination therapy. In the future, studies that include the profile of antibiotic-resistant bacteria and the monitoring of serum aminoglycoside levels will be required. [ABSTRACT FROM AUTHOR]

Background: Subclinical hypothyroidism, defined by elevated thyrotropin (TSH) and normal free thyroxine levels, is associated with adverse pregnancy outcomes, including preterm birth, pre-eclampsia, and small for gestational age. Despite the uncertainty regarding the effectiveness of levothyroxine (LT4) treatment on pregnancy outcomes in subclinical hypothyroidism, LT4 is widely administered with a pre-treatment threshold TSH level of 2.5 mU/L. The aim of this study is to investigate the efficacy of periconceptional LT4 treatment for subclinical hypothyroidism, including TSH levels >2.5 mU/L, and identify the characteristics of subclinical hypothyroidism that can benefit from LT4 treatment. Methods: We conducted a systematic review and meta-analysis of randomized controlled trials from inception to February 2023. We analyzed the pooled effects of LT4 on subclinical hypothyroidism before and during pregnancy. The main outcomes before pregnancy were live birth, pregnancy, and miscarriage. The main outcomes during pregnancy were live birth, miscarriage, and preterm birth. We conducted subgroup analyses to compare the effects of LT4 on subclinical hypothyroidism with TSH levels of 2.5–4.0 and >4.0 mU/L. Results: Of the 888 studies identified, 27 full-text articles were screened for eligibility. Five studies on pre-conception treatment with 768 participants and eight studies on treatment during early pregnancy with 2622 participants were analyzed. One of the two studies on pre-conception treatment in subclinical hypothyroidism with TSH >4.0 mU/L had high risk of bias and the other was composed of 64 participants. Pre-conception LT4 treatment had no significant effect in improving rates of live births and pregnancies, or reducing miscarriages (risk ratio [RR], 95% confidence interval): 1.41 (0.84–2.36), 1.73 (0.88–3.39), and 0.46 (0.11–2.00), respectively. LT4 treatment during pregnancy was not significantly associated with higher rates of live births (RR 1.03, 0.98–1.09) nor decreased miscarriage rates (RR 1.01, 0.66–1.53). The effect of LT4 treatment on preterm birth during pregnancy was significantly different depending on the TSH values (p = 0.04); a positive effect was shown in the subclinical hypothyroidism subgroup with TSH >4.0 mU/L (RR 0.47, 0.20–1.10), while no significant effect was observed in the subgroup with TSH 2.5–4.0 mU/L (RR 1.35, 0.79–2.31). Conclusions: Pre-conceptional LT4 treatment for subclinical hypothyroidism does not improve fertility or decrease the incidence of miscarriages. However, further well-designed studies are needed for pre-conceptional treatment, especially in TSH >4.0 mU/L. LT4 treatment during pregnancy had a positive effect on preterm birth; nevertheless, this was only applicable to subclinical hypothyroidism with TSH >4.0 mU/L. [ABSTRACT FROM AUTHOR]

Aim: Higher levels of perceived control are important to maintain health. The difference in factors related to perceived control and preventive behaviors during the COVID‐19 pandemic between Japanese and American nursing students remains unknown. This study aimed to compare factors related to perceived control and infection preventive behaviors between the two countries. Methods: This cross‐sectional study included nursing students attending four universities in Japan and one in the United States. Using Google Forms, the participants answered a survey comprising sociodemographic data, the Perceived Control and Self‐Efficacy Scale, the Perceived Health Competence Scale, and a preventive behavior questionnaire. The data were collected from November 2020 to May 2021. Linear and logistic regressions were used to analyze the factors related to perceived control and preventive behaviors, respectively. Results: Data from 878 students were analyzed. University/campus emerged as a strong predictor for perceived control and preventive behaviors in both countries, with a positive correlation between perceived control and preventive behaviors. Older age, less frequent alcohol consumption, higher perceived health competence, less frequent work in Japan; and chronic conditions in the United States were associated with frequent preventive behaviors. Younger age was correlated with higher perceived control in Japan, while religion and increased workload were potential factors for American students. Conclusion: Individual factors were pivotal in Japan, whereas interpersonal factors were more likely related to perceived control in the United States. Additionally, in both countries, policy or organizational factors significantly influenced students' preventive behaviors. [ABSTRACT FROM AUTHOR]

Japan has accepted nurses from Indonesia, the Philippines, and Vietnam under the Economic Partnership Agreement, but nearly half of them have already left the workforce. This study aimed to clarify the factors related to the job continuance of nurses who migrated to Japan under the Economic Partnership Agreement. Our goal was to explore factors specific to migrant nurses and to contribute to the development of support measures for them. This research was a cross-sectional study in which a web-based questionnaire and interview were conducted at a single point in time. Migrant nurses (n = 40) participated in the web-based questionnaire survey. Of those, nine nurses were also interviewed. Spearman's rank correlation coefficient was used to establish correlations, and qualitative descriptive analysis was used to analyse interviews. The questionnaire survey results revealed the content of work, human relationships in the workplace, the number of night shifts, and satisfaction with the balance between work and private life were significantly and negatively correlated with the Intention to Quit scale total score. All correlation coefficients were less than 0.5, indicating weak correlations. Three categories emerged from the interviews as positive factors related to job continuance: "generous support from the workplace", "beneficial nursing experience in Japan", and "determination to live in Japan". A good working environment, generous support from the supervisor and colleagues, high values of nursing in Japan, and desire to migrate to Japan were the factors that had a positive effect on migrant nurses' job continuance in Japan. Understanding the characteristics of migrant nurses and providing generous support will enable them to continue working in Japan. This study was not registered. [ABSTRACT FROM AUTHOR]

Tilapia masculinization can be induced by oral administration of A-methyltestosterone (MT), which is commonly dissolved in ethanol to be added to the feed. However, there are many benefits in using alternative vehicles, such as oil. The incorporation time, vehicles quantity, safety for handlers, fish and the environment are favorable factors. In fry fed for 35 days under temperature control, we found that masculinization rate was similar in both incorporation vehicles of MT (oil or ethanol) in the concentrations studied (30 and 60 mg MT kg-1 feed). In an experiment, using hormone oil dissolution and oral administration at 30 mg MT kg-1 feed, it was observed that the longer the administration time, the lower the coefficient of variation in the masculinization rate. Therefore, administration for 32 days showed the lowest variability in the masculinization rate (99.8 ± 0.5 %), compared to 24 (98.5 ± 3.0 %), 16 (97.0 ± 6.0 %) and 8 (89.0 ± 8.8 %) days. The field experiment confirmed the results obtained in the lab. We concluded that the oil can be used as MT vehicle and we recommend to dispense it at the lowest hormonal concentration (30 mg MT kg-1 feed) for 32 days for tilapia masculinization.

Diabetes is a chronic illness that negatively impacts quality of life. However, the quality of life of people with type 2 diabetes could be improved with sufficient literacy and abilities to perform self-management, such as managing blood glucose, maintaining a healthy diet, and proper exercise. This descriptive cross-sectional study aimed to describe the relationships among health literacy, self-management, and quality of life and to determine the predictors of quality of life of people with type 2 diabetes. Data were collected through purposive sampling from 218 individuals with type 2 diabetes in Manado City, Indonesia, between July and October 2021. We used the European Health Literacy Survey Questionnaire, Diabetes Self-management Questionnaire, and Diabetes Quality of Life Questionnaire. Data were analyzed using descriptive statistics, Pearson's product-moment correlation, and hierarchical regression analysis. The study revealed that health literacy was significantly associated with self-management and quality of life. Furthermore, age, occupation, health literacy, and self-management were significant predictors and collectively explained 25.3% of the variance in quality of life. Hence, higher health literacy and improved self-management practices were linked to a higher quality of life for people with type 2 diabetes. Since the explained variance of quality of life in this study is only 25.3%, further studies should include other factors such as social and family support and communication with health care providers to predict quality of life. Nevertheless, nurses can use this study to design interventions to improve self-care management skills and health literacy levels, which may enhance quality of life. However, testing the effectiveness is needed. [ABSTRACT FROM AUTHOR]

Background: Nutritional counseling, which includes two‐way interactive education, has been hypothesized to improve the health and nutritional status of pregnant women, but little is known about the impact such practice of care might have on maternal and infant health and behavioral outcomes of pregnant women living in low income, low‐middle income, and upper‐middle‐income countries (LMIC)s. Objectives: We conducted a systematic review to appraise the effectiveness and impact on health equity of two‐way nutritional counseling practices in LMICs on maternal and infant behavioral, nutritional, and health outcomes. Search Methods: We conducted electronic searches for relevant studies on Medline, Embase, CINAHL, PsychInfo, and the Cochrane CENTRAL for randomized and non‐randomized trials on the effectiveness of two‐way interactive nutritional counseling among pregnant women from the date of database inception up to June 22, 2021. In addition, we searched references of included studies in systematic reviews, gray literature resources, and unpublished studies or reports that satisfied our eligibility criteria using a focused Google search. Selection Criteria: We included randomized and non‐randomized controlled studies (NRS), controlled before and after, and interrupted time series that assessed the effectiveness of two‐way interactive nutrition counseling targeting pregnant women in LMICs. Data Collection and Analysis: Data extraction and risk of bias were conducted in duplicate. The risk of bias (ROB) for randomized trials (RCT) was assessed according to the Cochrane Handbook of Systematic Reviews, and ROB for NRS was assessed using the Newcastle‐Ottawa scale (NOS). RCT and NRS were meta‐analyzed separately. Main Results: Our search identified 6418 records and 52 studies met our inclusion criteria, but only 28 were used in the quantitative analysis. Twenty‐eight studies were conducted in Asia, the most in Iran. Eight studies were conducted in Africa. Two‐way interactive nutritional counseling during pregnancy may improve dietary caloric intake (mean difference [MD]: 81.65 calories, 95% confidence interval [CI], 15.37–147.93, three RCTs; I2 = 42%; moderate certainty of evidence using GRADE assessment), may reduce hemorrhage (relative risk [RR]: 0.63; 95% CI, 0.25–1.54, two RCTs; I2 = 40%; very low certainty of evidence using GRADE assessment), may improve protein (MD: 10.44 g, 95% CI, 1.83–19.05, two RCTs; I2 = 95%; high certainty of evidence using GRADE assessment), fat intake (MD: 3.42 g, 95% CI, −0.20 to 7.04, two RCTs; I2 = 0%; high certainty of evidence using GRADE assessment), and may improve gestational weight gain within recommendations (RR: 1.84; 95% CI, 1.10–3.09, three RCTs; I2 = 69%). Nutrition counseling probably leads to the initiation of breastfeeding immediately after birth (RR: 1.72; 95% CI, 1.42–2.09, one RCT). There was little to no effect on reducing anemia (RR: 0.77; 95% CI, 0.50–1.20, three RCTs; I2 = 67%; very low certainty of evidence using GRADE assessment) risk of stillbirths (RR: 0.81; 95% CI, 0.52–1.27, three RCTs; I2 = 0%; moderate certainty of evidence using GRADE assessment) and risk of cesarean section delivery (RR: 0.96; 95% CI, 0.76–1.20, four RCTs; I2 = 36%; moderate certainty of evidence using GRADE assessment). Authors' Conclusions: Our review highlights improvements in maternal behavioral and health outcomes through interactive nutrition counseling during pregnancy. However, we are uncertain about the effects of nutrition counseling due to the low certainty of evidence and a low number of studies for some key outcomes. Moreover, the effects on health equity remain unknown. More methodologically rigorous trials that focus on a precise selection of outcomes driven by the theory of change of nutrition counseling to improve maternal and infant behavioral and health outcomes and consider equity are required.

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: This study aimed to assess the feasibility and acceptability of an oral health self-care e-learning intervention for overseas workers as well as the research procedures for a future controlled trial. Methods: We randomly allocated participants to either the intervention (n = 48) or control (n = 51) group. The intervention group received a standardized leaflet plus a theory-based oral health e-learning program. The control group received only the standardized leaflet. We assessed health behaviour related to fluoride toothpaste use, oral care knowledge, motivation, oral care self-efficacy, and oral health related quality of life (QoL). Chi-square and t test analyses were performed to make comparisons between the two groups. To evaluate the research process, participants in the intervention group were asked open-ended questions to assess the acceptability and feasibility of the research procedures in practice. Results: A total of 82 participants (Intervention = 36, Control = 46) were included in the analysis. The dropout rate was 17.2%. The modal time taken to complete the e-learning intervention was more than 30 min (33.3%). Of the 36 respondents in the intervention group, 27 (70.4%) said that the e-learning intervention had changed their behaviour. At the three months follow-up, oral care knowledge alone was improved in the e-learning group. Conclusion: This pilot study provides evidence that the theory-based self-care for oral health e-learning intervention is feasible in overseas workers. Next, this feasible and acceptable pilot study should be used with an appropriate sample size in a randomized controlled trial. Trial registration: The trial protocol was registered with UMIN-CTR (ID: UMIN000045883) on 27/10/2021. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic has forced lifestyles changes and affected the relationships between fathers and their infants. However, the factors associated with paternal–infant bonding have not been clarified. This study aimed to explore the factors associated with father–infant bonding during the COVID-19 pandemic in Japan. This cross-sectional study used data from a nationwide survey and the Japanese version of the Mother-to-Infant Bonding Scale (MIBS) to measure father–infant bonding. The participants were divided into two groups depending on their partners' parity. A linear regression model (Gauss–Markov-type) was used for both groups. A total of 1055 men were included in the analysis. Of these men, 521 (49.4%) had a primipara partner, and 534 (50.6%) had a multipara partner. No significant differences were found between the two groups' MIBS-J scores. Fathers' mental health, relationship with the partner and family members, abusive behavior towards children, wanted pregnancy, and the youngest child's Neonatal Intensive Care Unit admission history were associated with father–infant bonding. Regarding factors related to COVID-19, caring for the child while the partner is at home has a negative impact on bonding, while fear related to infection with COVID-19 has no negative impact on bonding.

Background: Antenatal magnesium sulphate (MgSO4) therapy given to women at risk of preterm birth reduced the risk of cerebral palsy in early childhood. However, its effect on longer-term neurological outcomes remains uncertain. This study aimed to assess the effects of antenatal MgSO4 therapy on school-age outcomes of preterm infants. Methods: We conducted a systematic review and meta-analysis. We searched MEDLINE, EMBASE, CENTRAL, and CINAHL for randomized controlled trials (RCTs). Two reviewers independently evaluated the eligibility for inclusion and extracted data. Results: Ten RCTs were included. Only two of them were on school-age outcomes. Antenatal MgSO4 therapy had no impact on cerebral palsy, hearing impairment, neurosensory disability, and death at school-age. Meta-analysis on mental retardation and visual impairment was not able to be performed due to different methods of evaluation. In the analysis of short-term outcomes conducted as secondary outcomes, antenatal MgSO4 therapy increased the risk of maternal adverse events with any symptom (3 RCTs; risk ratio 2.79; 95% confidence interval 1.10 to 7.05, low certainty of evidence) but was not associated with any neonatal symptoms. Conclusions: The number of cases was insufficient to determine the impact of antenatal MgSO4 therapy on school-age outcomes. Further accumulation of long-term data is required.

Background and Aims: Mechanical ventilation is associated with several risks, including barotrauma, ventilator‐associated pneumonia, and ventilator‐induced diaphragmatic dysfunction. A delay in weaning from mechanical ventilation increases these risks, and prolonged weaning has been shown to increase hospital mortality. Various tools have been used in clinical practice to predict successful weaning from mechanical ventilation; however, they have a low prognostic accuracy. The use of ultrasonography in intensive care units is an area of growing interest since it is a noninvasive, convenient, and safe modality. Since ultrasonography can provide real‐time assessment of diaphragmatic morphology and function, it may have clinical utility in predicting successful mechanical ventilator weaning. This study aimed to describe a protocol to assess the effectiveness of diaphragmatic ultrasonography in the decision‐making process for ventilator weaning in terms of its impact on clinical outcomes. Methods: This systematic review of published analytical research will use an aggregative thematic approach according to the Preferred Reporting Items for Systematic Review and Meta‐Analysis Protocols guidelines. We will perform a comprehensive search for studies on the MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases. Two authors will independently perform abstract and full‐text screening and data extraction. Additionally, a meta‐analysis and the risk of bias evaluation will be conducted, as appropriate. Conclusion: Systematic reviews on the effectiveness of diaphragmatic ultrasonography in the decision‐making process for ventilator weaning in terms of its impact on clinical outcomes are lacking. The results of this systematic review may serve as a basis for future clinical trials. Systematic review registration: This protocol was registered with the Open Science Framework: https://osf.io/cn8xf. Key points: What is known: Delayed weaning from mechanical ventilation is associated with ventilator‐related lung injury and ventilator‐related complications.What is new: Currently, predicting the success of ventilator weaning based on physical examination alone is complicated, and a predictive index for successful weaning has not yet been established. However, the findings of the systematic review are expected to serve as a foundation for future clinical trials.Clinical implication: Carrying out this systematic review on the effectiveness of diaphragmatic ultrasonography during ventilator weaning will help translate the evidence on the new ventilator weaning index into clinical practice.

This systematic review aimed to compare extended infusion or continuous infusion with bolus infusion for febrile neutropenia (FN). We included clinical trials comparing extended or continuous infusion with bolus infusion of beta-lactam antibiotics as empirical treatment for FN and evaluated the clinical failure, all-cause mortality, and adverse event rates. Five articles (three randomized controlled trials (RCTs) and two retrospective studies) from 2014 to 2022 were included. Clinical failure was assessed with a risk ratio (RR) (95% coincident interval (CI)) of 0.74 (0.53, 1.05) and odds ratio (OR) (95% CI) of 0.14 (0.02, 1.17) in the 2 RCTs and retrospective studies, respectively. All-cause mortality was assessed with an RR (95% CI) of 1.25 (0.44, 3.54) and OR (95% CI) of 1.00 (0.44, 2.23) in the RCTs and retrospective studies, respectively. Only 1 RCT evaluated adverse events (with an RR (95% CI) of 0.46 (0.13, 1.65)). The quality of evidence was "low" for clinical failure and all-cause mortality in the RCTs. In the retrospective studies, the clinical failure and all-cause mortality evidence qualities were considered "very low" due to the study design. Extended or continuous infusion of beta-lactam antibiotics did not reduce mortality better than bolus infusion but was associated with shorter fever durations and fewer adverse events.

Introduction: Because excessive physical stress is harmful, reducing pain and discomfort in premature neonates during mechanical ventilation is a major challenge for physicians. There are no consensus and systematic review on the use of fentanyl, the most commonly used pain reliever in preterm neonates during mechanical ventilation. We aim to compare the benefits and harms of fentanyl versus placebo or no drug for preterm neonates receiving mechanical ventilation. Methods: A systematic review of randomized controlled trials (RCTs) was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions. The systematic review was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Scientific databases such as MEDLINE, Embase, CENTRAL, and CINAHL were searched. All preterm infants on mechanical ventilation and enrolled in an RCT of fentanyl versus control were included. Results: Of 256 reports initially retrieved, 4 reports met the eligibility criteria. Fentanyl was not associated with mortality risk compared to the control (risk ratio: 0.72, 95% confidence intervals [CIs]: 0.36–1.44). No increase in ventilation duration (mean difference [MD]: 0.04, 95% CIs: −0.63–0.71) and no effect on hospital stay length (MD: 4.00, 95% CIs: −7.12–15.12) were found. Fentanyl intervention does not affect any other morbidities, including bronchopulmonary dysplasia, periventricular leukomalacia, patent ductus arteriosus, intraventricular hemorrhage (IVH), severe IVH, sepsis, and necrotizing enterocolitis. Conclusion: The present systematic review and meta-analysis failed to demonstrate the benefit of administering fentanyl to preterm infants on mechanical ventilation in mortality and morbidities. Follow-up studies are required to investigate the long-term neurodevelopment of the children. [ABSTRACT FROM AUTHOR]

This systematic review aimed to identify the benefits and possible harms of tocolytic therapy for preterm labour management in the context of pregnant women with extremely preterm birth, multiple gestations, or growth-restricted foetuses. A comprehensive search using MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, CINAHL, and the WHO Global Index Medicus databases was conducted from 10 to 15 July 2021. We included randomized controlled trials and non-randomized studies that assessed the effects of tocolysis compared with placebo or no treatment. We found 744 reports and, finally, nine studies (three randomized controlled trials and six cohort studies) pertaining to women with <28 weeks of gestation were included. No eligible studies were identified among women with a multiple pregnancy or a growth-restricted foetus. A meta-analysis of the trial data showed that there were no clear differences in perinatal death nor for a delay in birth. Non-randomized evidence showed that tocolysis delayed birth by 7 days, though there was no clear difference for preterm birth. In summary, it remains unclear whether tocolytic therapy for inhibiting preterm labour is beneficial for these subgroups of women and their newborns. Further well-designed randomized controlled trials and observational studies are needed to address the lack of evidence regarding tocolytic agents in these populations. [ABSTRACT FROM AUTHOR]

The objective of this review is to assess and synthesize the role of the maternal and child health (MCH) handbook on improving healthcare service utilization, behavior change, and health outcomes for women and children. A systematic search of all relevant existing reports was conducted on 14 January 2021, using the following online bibliographic databases: PubMed, EMBASE, MEDLINE, The Cochrane Library, Academic Search Premier, Emcare, APA PsycINFO, and Web of Science. Two reviewers independently performed study selection, data extraction, and quality assessment. We included 7 trials from 1430 articles, and a total of 2643 women. As overall risk of bias assessment, most domains of the Cochrane risk-of-bias assessment tool showed a high or unclear risk of bias. The risk of ≥6 antenatal care (ANC) visits was 19% higher (RR 1.19, 95% CI 1.09 to 1.30, I2 = 47%, 2 studies, 955 women, moderate certainty of evidence) and skilled birth attendants during delivery was 13% higher (RR 1.13, 95% CI 1.04 to 1.24, I2 = 0%, 2 studies, 1094 women, low certainty of the evidence) in the intervention group than in the control group. The MCH handbook can increase maternal health service utilization and early breastfeeding practice. It also leads to a sense of autonomy during ANC, better communication with healthcare providers, and support from family members. [ABSTRACT FROM AUTHOR]

Simple Summary: Empirical administration of broad-spectrum antibiotics during neutropenia has been shown to reduce mortality from bacterial infections. However, prolonged antibiotic exposure, in particular, promotes the development of antimicrobial resistance and the selection of resistant microorganisms, which are often more difficult to treat, and carry a higher risk of complications. Early antibiotic discontinuation has been proposed in patients with hematologic malignancy who have febrile neutropenia. Several studies have found that shorter duration of antimicrobial therapy have better clinical outcomes and lower the exposure to the broad-spectrum antibiotics, but this raises concerns about their implementation in clinical practice. Furthermore, their safety and efficacy have been questioned. In our study, a systematic review was conducted to compare the short-term and long-term durations of antibiotics for febrile neutropenia for the outcomes of clinical failure, mortality, and bacteremia. Early antibiotic discontinuation has been proposed in patients with hematologic malignancy with fever of unknown origin during febrile neutropenia (FN). We intended to investigate the safety of early antibiotic discontinuation in FN. Two reviewers independently searched for articles from Embase, CENTRAL, and MEDLINE on 30 September 2022. The selection criteria were randomized control trials (RCTs) comparing short- and long-term durations for FN in cancer patients, and evaluating mortality, clinical failure, and bacteremia. Risk ratios (RRs) with 95% confidence intervals (CIs) were calculated. We identified eleven RCTs (comprising 1128 distinct patients with FN) from 1977 to 2022. A low certainty of evidence was observed, and no significant differences in mortality (RR 1.43, 95% CI, 0.81, 2.53, I2 = 0), clinical failure (RR 1.14, 95% CI, 0.86, 1.49, I2 = 25), or bacteremia (RR 1.32, 95% CI, 0.87, 2.01, I2 = 34) were identified, indicating that the efficacy of short-term treatment may not differ statistically from that of long-term treatment. Regarding patients with FN, our findings provide weak conclusions regarding the safety and efficacy of antimicrobial discontinuation prior to neutropenia resolution. [ABSTRACT FROM AUTHOR]

In the context of mental health, university students have been considered a vulnerable population. However, limited studies have underscored the association between preventive health behaviour levels and mental health effects among nursing students. The current cross‐sectional study provides a comparative analysis of the impact of mental health factors on nursing students in Japan and the United States (US) in the context of the coronavirus disease 2019 (COVID‐19) pandemic. The study consisted of 878 participants, comprising both undergraduate and graduate nursing students from four universities in Japan, and one from the US. Hierarchical logistic regression was used to analyse the participant data in this study. In contrast to the American students, the Japanese students demonstrated significantly lower levels of perceived control and significantly higher levels of preventive health behaviours. Furthermore, Japanese students exhibited significantly higher levels of stress and/or symptoms of depression induced by the social distancing orders compared to the American students (z = −4.218, P < 0.001). However, no difference was observed after adjusting for perceived control, individual factors, socio‐economic factors, and preventive behaviours. During the pandemic, risk factors that can worsen mental health among the nursing students included younger age [odds ratio (95%CI) = 0.62 (0.48–0.81)], women [OR = 2.17 (1.02–4.61)], higher preventive health behaviour [OR = 1.05 (1.02–1.08)], lower perceived control [OR = 0.97 (0.94–0.99)], and lower perceived health competence [OR = 0.93 (0.90–0.96)]. Thus, this study recommends establishing training programmes that enhance perceived control and perceived health competence while encouraging preventive behaviour to support the mental health of nursing students, particularly young female students.

Background: Over the years, bronchopulmonary dysplasia (BPD) affects the pulmonary function of infants, resulting in chronic health burdens for infants and their families. The aim of this scoping review was to screen available evidence regarding perinatal risk factors associated with the development and severity of BPD. Methods: The eligibility criteria of the studies were year of publication between 2016 and 2021; setting of a developed country; English or Japanese as the study language; and randomized controlled, cohort, or case-control design. The titles and abstracts of the studies were screened by independent reviewers. Results: Of 8189 eligible studies, 3 were included for severe BPD and 26 were included for moderate BPD. The risk factors for severe BPD were male sex, iatrogenic preterm birth, maternal hypertensive disorders of pregnancy (HDP), low gestational age, small-for-gestational-age (SGA) birth weight, mechanical ventilation on day 1, and need for patent ductus arteriosus (PDA) management. The risk factors for moderate or severe BPD included male sex, premature rupture of membranes, clinical chorioamnionitis, maternal HDP, SGA birth weight, bubbly/cystic appearance on X-ray, and PDA management. Conclusions: We identified several risk factors for BPD. We plan to confirm the validity of the new classification using the existing dataset. [ABSTRACT FROM AUTHOR]

In Japan, mean birth weight has significantly decreased from 3152 g in 1979 to 3018 g in 2010 and the prevalence of preterm birth (PTB) has risen to 5.7% in the last thirty years. However, the presence and magnitude of geographical differences in low birthweight (LBW) and/or PTB in Japan is not well understood. We implemented spatial analysis to identify localized clusters and hot spots of LBW and/or PTB during 2012–2016. The Japan national birth database was used in this study. A total of 5,041,685 (male: 2,587,415, female: 2,454,270) births were used for spatial analysis using empirical Bayes estimates of the incidence rate of LBW and/or PTB and spatial scan tests to detect hot-spot areas with p values calculated from Monte Carlo iterations. The most and second likely clusters were located in two areas: (1) the small islands in south-west Japan (Amami and Okinawa, Relative risk = 1.09–1.67 with p < 0.001) and (2) the cities on the base of Mt. Fuji, stretching over three neighboring prefectures of Yamanashi, Shizuoka and Kanagawa (Relative risk = 1.10–1.55 with p < 0.001), respectively. We need to optimize the medical resource allocations based on the evidence in geographical clustering of LBW and/or PTB at specific locations in Japan. [ABSTRACT FROM AUTHOR]

Purpose: Tamoxifen is used for the suppression of estrogen‐sensitive tumor recurrence in oocyte retrieval cycles. This meta‐analysis aimed to evaluate the quality of controlled ovarian stimulation (COS) with co‐administration of gonadotropins and tamoxifen (COS with tamoxifen). Methods: PubMed, Embase, and Cochrane Library were searched for articles on October 30, 2022. The authors included studies comparing COS with tamoxifen and COS with gonadotropins and letrozole (COS with letrozole) or gonadotropin only (COS with gonadotropin only) for fertility preservation in patients with breast cancer. The main outcome measures were the COS quality, total number of retrieved oocytes (TOR), total number of mature oocytes (TMO), and peak estradiol levels (PEL). Results: Four studies (348 patients, two randomized controlled trials, and two cohort studies) were included in our meta‐analysis. There was no significant difference in TOR (95% CI, [−3.84, 2.90]) and TMO (95% CI, [−2.20, 2.64]) between COS with tamoxifen and COS with letrozole. There was also no difference in TOR (95% CI, [−6.14, 1.86]) between COS with tamoxifen and COS with gonadotropin only. Statistically significant decrease was observed in PEL during COS with letrozole compared with tamoxifen (95% CI, [1414.4, 4953.7]). Conclusions: The quality did not differ between COS with tamoxifen and COS with letrozole or gonadotropin only. [ABSTRACT FROM AUTHOR]

Aim: The aims of the study were to synthesize the role of technology‐based healthcare interventions (TBIs) and to identify the most effective interventions for the best functional maternal and child health (MCH) outcomes among low‐risk pregnant women in low‐ and middle‐income countries (LMICs). Design: A systematic review and network meta‐analysis (NMA). Methods: We will perform a comprehensive search in electronic databases and other resources to identify relevant randomized controlled trials. Two reviewers will independently perform study selection, data extraction and quality assessment. Our primary outcomes include proportion of recommended antenatal care visits, skilled delivery care, postnatal care visits and exclusive breastfeeding practices. We will use pairwise random‐effects meta‐analysis and NMAs to estimate direct, indirect and relative effects using the relevant intervention classifications for each outcome separately. We plan to assess hierarchy of interventions, statistical inconsistency and certainty of evidence. Results: This review will compare the effectiveness of different form of TBIs on a comprehensive range of MCH outcomes and will provide the outcome‐specific reliable evidence of the most effective interventions on improving MCH in LMICs. The review findings will guide researchers, stakeholders or policymakers on the potential use of TBIs in the given contexts that could achieve the best functional MCH outcomes in LMICs.

Simple Summary: Despite the potential benefits of effective communication, telling children about unpredictable and life-threatening conditions such as cancer is challenging. This scoping review aimed to map the potential communication tools for children with cancer, their families, and healthcare professionals. We found 25 studies and 21 communication tools. Communication tools might support children to improve their knowledge and psychological outcomes. However, we found a lack of communication tools that were (1) accessible and validated, (2) designed for healthcare professionals, (3) targeted children, families, and healthcare professionals, and (4) were designed to meet the needs of children and families. This review identified areas for further research. Background: Although communication tools might guide healthcare professionals in communicating with children about cancer, it is unclear what kind of tools are used. This scoping review aimed to map the communication tools used in cancer communication among children with cancer, families, and healthcare professionals. Methods: A comprehensive search using PubMed (including MEDLINE), Embase, CENTRAL, PsycINFO, and CINAHL was conducted on 1 August 2021. We mapped communication tools and their impacts. Results: We included 25 studies (9 experimental studies and 16 feasibility studies) of 29 reports and found 21 communication tools. There was a lack of communication tools that were (1) accessible and validated, (2) designed for healthcare professionals, (3) targeted children, families, and healthcare professionals, and (4) were designed to meet the needs of children and families. Experimental studies showed that the communication tools improved children's knowledge and psychological outcomes (e.g., health locus of control, quality of life, self-efficacy). Conclusion: We mapped communication tools and identified areas that needed further research, including a lack of tools to guide healthcare professionals and share information with children and families. Further research is needed to develop and evaluate these communication tools. Moreover, it is necessary to investigate how communication tools support children, families, and healthcare professionals. [ABSTRACT FROM AUTHOR]

Aim: This clinical practice guideline aims to provide and recommend methods of assessing aspiration and pharyngeal residue during eating and swallowing and methods of selecting and implementing nursing care for adults to prevent the development of aspiration pneumonia through early and appropriate management of oropharyngeal dysphagia. Methods: In April 2018, the Japan Academy of Nursing Science established the Supervisory Committee in Nursing Care Development/Standardization Committee to develop clinical practice guidelines for aspiration and pharyngeal residual assessment during eating and swallowing for nursing care. This clinical practice guideline was developed according to the Minds Manual for Guideline Development 2017, with the aim of providing a specific pathway for nurses to determine the policy for selecting management for oropharyngeal dysphagia based on research evidence and multifaceted factors including the balance of benefits and harms and patients' values. Results: Based on the 10 clinical questions related to assessment by physical assessment, the Repetitive Saliva Swallowing Test, Modified Water Swallowing Test, Food Test, cervical auscultation, observation using an ultrasound diagnostic device, and an endoscope, 10 recommendations have been developed. Eight recommendations have been evaluated as the Grading of Recommendations Assessment, Development and Evaluation (GRADE) 2C, and the other two have been evaluated as no GRADE. Conclusion: The first reliable clinical practice guideline has been produced from an academic nursing organization that focuses on assessment for nursing care and incorporates the latest findings.

There is no standard birth weight curve for twins in Japan other than a prototype curve based on 1988–1991. Twins have a high perinatal mortality rate than singletons; therefore, we developed a new standard curve for twin birth weight using data from the 1995–2016 Vital Statistics and compared it with previous reports. We used 469,064 cases for analysis, excluding stillbirths and cases with missing values, and created a standard curve using LMS (statistical methods to vary the distribution by using skewness, median, and coefficient of variation) method. In comparison with previous reports, the mean birth weight decreased by 100–200 g. The groups with the lowest neonatal death rates (NDRs) and infant death rates (IDRs) were those with a birth weight of 1,500–2,499 g (NDR: 0.3%, IDR: 0.6%) and those born at 34–36 weeks (NDR: 0.2%, IDR: 0.4%). Compared to these, the IDR was significantly higher in the 2,500–3,999 g group and the 37–39 weeks group (incidence rate ratio (IRR): 1.1 in the 2,500–3,999 g group, IRR: 1.3 in the 37w0d–39w6d group). In particular, the risks of neonatal mortality and infant mortality were higher in infants born at a birth weight above 3,500 g. Infants born at a birth weight above 3,500 g may include recipients of twin-to-twin transfusion syndrome. The most common causes of infant mortality are accidental death and sudden infant death syndrome (SIDS). We considered the possibility that infants treated as healthy newborns and whose mothers were discharged from the hospital without adequate twin care guidance may be more likely to experience unintentional accidents and SIDS at home. The present study suggested that creating a new twin birth weight standard curve and guidance on managing twins at home for full-term and normal birth weight infants may lead to a reduction in infant deaths.

Background: Despite the potential benefits of effective communication, telling a child that they have a life-threatening condition is one of the most daunting challenges. This study aimed to explore the information needs of children with leukemia from the perspectives of children and their parents at the time of diagnosis.Methods: We conducted an exploratory qualitative study using semi-structured individual interviews with children diagnosed with leukemia between seven and 13 years old (n = 7) and their parents (n = 9). Children and parents' interview data were analyzed using thematic analysis.Results: We identified three themes for the information needs of children with leukemia, 1) beginning to cope, 2) avoiding disclosure - protecting child, and 3) informational support. The children and their parents needed to receive understandable information at the best time to cope with cancer. However, the children and parents expressed different views about children's information needs. The children needed clear information about the disease, treatment, hospitalization, and the benefits of hospitalization from the time of diagnosis. In contrast, the parents felt they should not tell their children about the disease if they were in shock by their child's cancer diagnosis. Moreover, the parents believed that information that would be incomprehensible to the child and distress should be avoided to protect their children.Conclusions: While the information needs of children with leukemia are varied, children and their parents need the information to cope with cancer. However, if the parents believe that the information would be distressful, they might manage communication with their children. Healthcare professionals should explore the motivations behind parents' attitudes against communication with children and confront conflict. Healthcare professionals also should communicate with the children and their parents to understand their information needs and respect children's views. [ABSTRACT FROM AUTHOR]

Objectives: To determine the relative effectiveness of medications for preventing hypertensive disorders in high-risk pregnant women and to provide a ranking of medications using network meta-analysis. Methods: All randomized controlled trials comparing the most commonly used medications to prevent hypertensive disorders in high-risk pregnant women that are nulliparity and pregnant women having family history of preeclampsia, history of pregnancy-induced hypertension in previous pregnancy, obstetric risks, or underlying medical diseases. We received the search results from the Cochrane Pregnancy and Childbirth's Specialised Register of Controlled Trials, searched on 31st July 2020. At least two review authors independently selected the included studies and extracted the data and the methodological quality. The comparative risk ratios (RR) and 95% confidence intervals (CI) were analyzed using pairwise and network meta-analyses, and treatment rankings were estimated by the surface under the cumulative ranking curve for preventing preeclampsia (PE), gestational hypertension (GHT), and superimposed preeclampsia (SPE). Safety of the medications is also important for decision-making along with effectiveness which will be reported in a separate review. Results: This network meta-analysis included 83 randomized studies, involving 93,864 women across global regions. Three medications, either alone or in combination, probably prevented PE in high-risk pregnant women when compared with a placebo or no treatment from network analysis: antiplatelet agents with calcium (RR 0.19, 95% CI 0.04 to 0.86; 1 study; low-quality evidence), calcium (RR 0.61, 95% CI 0.47 to 0.80; 13 studies; moderate-quality evidence), antiplatelet agents (RR 0.69, 95% CI 0.57 to 0.82; 31 studies; moderate-quality evidence), and antioxidants (RR 0.77, 95% CI 0.63 to 0.93; 25 studies; moderate-quality evidence). Calcium probably prevented PE (RR 0.63, 95% CI 0.46 to 0.86; 11 studies; moderate-quality evidence) and GHT (RR 0.89, 95% CI 0.84 to 0.95; 8 studies; high-quality evidence) in nulliparous/primigravida women. Few included studies for the outcome of superimposed preeclampsia were found. Conclusion: Antiplatelet agents, calcium, and their combinations were most effective medications for preventing hypertensive disorders in high-risk pregnant women when compared with a placebo or no treatment. Any high-risk characteristics for women are important in deciding the best medications. The qualities of evidence were mostly rated to be moderate.

Introduction and hypothesis: Directed pushing while using the Valsalva maneuver is shown to lead to bladder neck descent, especially in women with urinary incontinence (UI). There is insufficient evidence about the benefits or adverse effects between the pushing technique during the second stage of labor and urinary incontinence postpartum. The objective of this study was to evaluate the effects of the pushing technique for women during labor on postpartum UI and birth outcomes. Methods: Scientific databases were searched for studies relating to postpartum urinary incontinence and birth outcomes when the pushing technique was used from 1986 until 2020. RCTs that assessed healthy primiparas who used the pushing technique in the second stage of labor were included. In accordance with Cochrane Handbook guidelines, risk of bias was assessed and meta-analyzed. Certainty of evidence was assessed using the GRADE approach. Results: Seventeen RCTs (4606 primiparas) were included. The change in UI scores from baseline to postpartum was significantly lower as a result of spontaneous pushing (two studies; 867 primiparas; standardized mean difference: SMD –0.18, 95% CI –0.31 to –0.04). Although women were in the recumbent position during the second stage, directed pushing group showed a significantly shorter labor by 21.39 min compared with the spontaneous pushing group: there was no significant difference in the duration of the second stage of labor between groups. Conclusions: Primiparas who were in the upright position and who experienced spontaneous pushing during the second stage of labor could reduce their UI score from baseline to postpartum.

The present study was carried out to evaluate the genotoxic potential of nutritional quality of feed, using erythrocytic nuclear abnormalities assay in Nile tilapia and its correlation with available nutrients and common fish growth biomarkers. For this, ten feeds commercialized in Brazil were assessed on digestibility and performance assays with triplicate groups. Venipuncture of the caudal vein for abnormalities analyzed was performed 102 days after the fish were fed with the commercial feed twice a day, to apparent satiation. Nuclear abnormalities were analyzed in blood smears. Principal component analysis and correlation matrix were used to carry out an exploratory analysis of correlation between frequency of abnormalities and performance parameters or available nutrients. The frequency of abnormalities in erythrocytes of Nile tilapia, fish performance, and digestibility were feed-dependent. It was observed correlations between the frequency of most abnormalities and performance parameters or content of nutrients. The frequency of kidney-shaped (6.23 ± 4.14), bud nuclei (2.99 ± 1.95), bridge nuclei (0.53 ± 0.50), and binuclei (0.43 ± 0.59) was the highest in fish that also presented the worst performance among all treatments and correlated with digestible methionine. Micronucleus frequency (0.33 ± 0.49) was higher in fish from the same group that presented depressed feed intake and lower available zinc. Only one group presented vacuolated nuclei and the frequency of this abnormality was correlated with available phosphorus. The frequency of abnormalities in erythrocytes is a fish sensitive indicator of health and plays an important role as a complementary tool in the assessment of fish feeding. The variation in the frequency of nuclear abnormalities in erythrocytes obtained among fish fed with the different feeds allows the assertion that they contained genotoxic factors.

Background: Excessive weight gain during pregnancy results in maternal and fetal complications and could further impact offspring. The evidence regarding the association between regular weighing during the antenatal period and excessive weight gain is limited. Methods: We will systematically review individual and cluster randomized controlled trials that evaluated regular weighing as an intervention compared to weighing only at the first booking of the antenatal visit. Trials that assessed the effectiveness of exercise, diet, or other behavioral interventions will be excluded. Pregnant women with a singleton pregnancy and no preexisting health complications are eligible for the review. The primary outcome will be the proportion of women at term who exceed the upper limit of the target range of weight as defined by the guidelines or recommendations for the population. We will search MEDLINE (via PubMed), Embase (via EMBASE.com), Scopus, the Cumulative Index to Nursing and Allied Health Literature (CINAHL via EBSCO), The Cochrane Central Register of Controlled Trials (CENTRAL) and the trial protocol registers, ClinicalTrials.gov, and the International Clinical Trials Registry Platform (ICTRP) search portal. Full-text articles, unpublished studies, and ongoing trials reported in any language will be included. Two review authors will independently examine and screen for eligible studies and extract data for synthesis. Discussion: We will discuss the effectiveness of regular weighing as a single intervention on reducing the proportion of women who have excessive gestational weight gain. This study will provide key information for countries to develop guidelines on antenatal care and strategies to tackle excessive gestational weight gain. We will create a "Summary of findings" table (Summary of findings table 1) according to the methods described in the Cochrane Handbook for Systematic Reviews of Interventions.

Background: Bronchopulmonary dysplasia (BPD) is a common and serious complication of extremely preterm birth. Given the anti-inflammatory properties, docosahexaenoic acid (DHA) supplementation has been proposed as a strategy for the management of BPD. This study aimed to investigate the effects of DHA supplementation on BPD based on a systematic review.Methods: A comprehensive literature search was conducted using ClinicalTrials.Gov, CINAHL, Cochrane Library, EMBASE, MEDLINE, PubMed, and the WHO ICTRP from their respective dates of inception to June 2017. The studies included were randomized controlled trials (RCTs) that enrolled preterm infants <33 weeks of gestational age. Trials were included if DHA supplementation was compared with a control.Results: Four RCTs from five reports (1,966 neonates) met our inclusion criteria. The meta-analysis of these studies showed that DHA supplementation did not decrease the risk of BPD at 36 weeks of postmenstrual age among preterm infants (low certainty of evidence). DHA supplementation did not significantly reduce the risk of other neonatal morbidities including death (low certainty of evidence), BPD at 28 days of life (moderate certainty of evidence), necrotizing enterocolitis (low certainty of evidence), intraventricular hemorrhage, severe retinopathy of prematurity, or sepsis.Conclusion: DHA supplementation may not exert significant clinical benefits in the treatment of BPD and other neonatal morbidities.

The objective of this systematic review is to identify, appraise and synthesise the best available evidence on the effectiveness of nutritional counselling and education interventions on maternal, infant and child health outcomes, and assess the differences in effects across participants' PROGRESS+ characteristics. To achieve these objectives, we will aim to answer the following research questions: What is the effectiveness of nutrition counselling interventions for pregnant women in low‐ or middle‐income countries on maternal, infant and child health outcomes? What are the impacts of nutrition counselling interventions on maternal, infant and child health outcomes across participants' PROGRESS+ characteristics? [ABSTRACT FROM AUTHOR]

Background: Preconception care aims to improve both maternal and child health in the short as well as long term, along with providing health benefits to adolescents, women, and men, whether or not they plan to become parents. However, there is limited evidence regarding the effectiveness of interventions for improving preconception health in population-based settings. To accumulate evidence in this field, this study focused on the concept of health literacy, and aimed to develop a self-report health literacy scale in Japanese, focusing on preconception care.Methods: We conducted a cross-sectional online survey. Participants were recruited from December 2019 to February 2020 from the registered members of a web-based research company. Participants were Japanese men and women aged 16-49 (n = 2000). A factor analysis was conducted to select both factors and items for health-related behavior and skills (33 initial items were generated), along with an item response theory analysis to examine how the 16 items were related to people's knowledge of preconception care.Results: We developed a 6-factor (including "appropriate medical examinations," "appropriate diet," "stress coping," "healthy weight," "safe living environment," and "vaccinations"), 25-item behavior and skills scale, as well as a 13-item knowledge scale, to evaluate participants' health literacy around preconception care. A shortened version, consisting of 17 items, was also prepared from the 25 items. The reliability coefficients of total scores and each factor of the behavior and skills scale were comparatively high, with weak-to-moderate correlation between behavior and skills and knowledge.Conclusions: The new scale will, ideally, provide information on the current state of preconception care health literacy of the general population. In addition, this scale, which consists of both behavioral/skills and knowledge dimensions, should help support the effective implementation of risk assessment programs and interventions aimed at promoting behavioral changes using a population-based approach. Future studies using different question/administration formats for diverse populations, and considering respondents' opinions on health literacy scales should be effective in improving this scale.

Background: Obese pregnant women are known to experience poorer pregnancy outcomes and are at higher risk of postnatal arteriosclerosis. Hence, weight control during and after pregnancy is important for reducing these risks. The objective of our planned randomized controlled trial is to evaluate whether the rate of change in body weight in obese women before pregnancy to 12 months postpartum would be lower with the use of an intervention consisting of Internet of Things (IoT) devices and mobile applications during pregnancy to 1 year postpartum compared to a non-intervention group.Methods: Women will be recruited during outpatient maternity checkups at four perinatal care institutions in Japan. We will recruit women at less than 30 weeks of gestation with a pre-pregnancy body mass index ≥ 25 kg/m2. The women will be randomly assigned to an intervention or non-intervention group. The intervention will involve using data (weight, body composition, activity, sleep) measured with IoT devices (weight and body composition monitor, activity, and sleep tracker), meal records, and photographs acquired using a mobile application to automatically generate advice, alongside the use of a mobile application to provide articles and videos related to obesity and pregnancy. The primary outcome will be the ratio of change in body weight (%) from pre-pregnancy to 12 months postpartum compared to before pregnancy.Discussion: This study will examine whether behavioral changes occurring during pregnancy, a period that provides a good opportunity to reexamine one's habits, lead to lifestyle improvements during the busy postpartum period. We aim to determine whether a lifestyle intervention that is initiated during pregnancy can suppress weight gain during pregnancy and encourage weight loss after delivery.Trial Registration: UMIN: UMIN (University hospital Medical Information Network) 000,041,460.

BACKGROUND: Universal prevention approaches that target the general population can be effective for promoting children's health. This overview aims to summarize evidence presented in existing reviews of school‐based interventions. METHODS: We present an overview of evidence sourced from Campbell and Cochrane systematic reviews. These reviews examined randomized controlled trials concerning school‐based health‐promotion programs for children (mostly aged 4‐18 years) in the general population. RESULTS: We identified 56 high‐quality reviews. The reviews focused on emotional and behavioral outcomes, infectious diseases, injury reduction, mental health, nutrition intake, oral health, physical and developmental changes, sense‐organ diseases, sexual‐health outcomes, and substance use/abuse. Positive evidence—such as vision screening plus provision of free spectacles for spectacle wear increase and a combination of social competence and social‐influence approaches for preventing illicit drug use—were considered high certainty. CONCLUSIONS: Of the various interventions implemented in school settings that involved people from various occupations, some positive effects were found. In most cases, evidence certainty was negatively affected by a high risk of bias within studies, inconsistencies within the estimates, and insufficient sample sizes. Further primary studies in these areas would be helpful for accumulating evidence to promote stronger cooperation between health and education stakeholders. [ABSTRACT FROM AUTHOR]

Background: Despite prophylactic human papillomavirus (HPV) vaccination being a safe, effective and cost-effective public health intervention for the prevention of cervical cancer, the HPV vaccine is not actively recommended or promoted by the Ministry of Health Labour and Welfare in Japan. With already very low levels of cervical screening below 30%, and vaccination levels that are below levels that award any population effect at 0.3% of the eligible population, cervical cancer mortality is higher than other similar high-income countries at 4.4/100,000 (2900) deaths per year in 2015. There is limited population-based or nationally representative data for HPV genotype distribution in Japan, thus making an assessment of the burden of vaccine-preventable cervical cancer difficult. Therefore, this systematic review and meta-analysis aims to determine the HPV genotype prevalence and age distribution of HPV infection in women with a cytological or histological diagnosis of normal through cervical cancer in Japan. We anticipate this information will guide and enhance programme interventions to reduce vaccine-preventable cervical cancer mortality in Japan. Methods: PubMed, Embase and the Japan Medical Abstract Society Database will be searched from the date of establishment to March 2021 to identify original research articles that report the prevalence of HPV genotypes in Japanese women with normal cervical cytology, low grade, high grade and cancerous cervical lesions. No exclusion criteria relating to language or publication date will be applied. The quality of the studies will be assessed using the Joanna Briggs checklist for prevalence studies. Randomised control trials, cohort studies, cross-sectional and prevalence studies will be considered eligible. Study findings will be combined using a traditional random-effects or fixed-effects meta-analysis to summarise pooled prevalence and 95% confidence intervals depending on heterogeneity. Subgroup analyses and meta-regression will be used to investigate heterogeneity, and sensitivity analyses will be conducted to assess the robustness of the findings. Discussion: To our knowledge, this is the first systematic review protocol that includes both Japanese and English peer-reviewed articles for the determination of genotype-specific HPV prevalence in cytological or histological confirmed normal cervical specimens, low- and high-grade intraepithelial lesions and cervical cancers by age in Japan. We anticipate this information will guide and enhance programme interventions to reduce vaccine-preventable cervical cancer mortality in Japan.

Aims: The associations of 2 nonsynonymous single nucleotide polymorphisms (Arg16Gly and Gln27Glu) in the adrenoceptor β2 (ADRB2) gene with response after albuterol use are conflicting. We conducted a meta‐analysis to examine the cumulative evidence of the effects of these 2 variants on percent forced expiratory volume in 1 second (FEV1.0%) after albuterol use in asthma patients. Methods: We conducted a comprehensive literature search using MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials to identify studies examining the association between ADRB2 Arg16Gly and Gln27Glu and FEV1.0% shortly after albuterol administration. The individual study results were combined with weights based on the inverse variance method. This systematic review was registered in the PROSPERO (registration number: CRD42019074554). Results: Among 273 initial studies identified, 7 studies met the inclusion criteria for quantitative evaluation. Results of the overall meta‐analysis indicated no statistically significant mean difference of FEV1.0% between genotypes of Arg16Gly and Gln27Glu. In subgroup analyses, significant associations were found for Arg16Gly GG (vs AA) among studies where no methacholine bronchoconstriction was conducted (mean difference, −3.92; 95% confidence interval, −7.29 to −0.54; I2 = 0%), and for Arg16Gly GG (vs GA) among studies that included patients with no comorbidities (mean difference, −1.93; 95% confidence interval, −3.77 to −0.10; I2 = 0%). Conclusion: Synthesis of the studies to date shows weak evidence for an association between ADRB2 Arg16Gly and Gln27Glu and FEV1.0% after albuterol use, results of which underscore significant heterogeneity across studies and the need for careful design and sample size considerations.

Aim: To estimate diagnostic accuracy of ultrasonography for detecting aspiration and pharyngeal residue in patients with dysphagia. Methods: A systematic search was conducted in MEDLINE (via PubMed), CINAHL, EMBASE, Ichushi‐Web, and Cochrane Library databases to identify articles that showed diagnostic accuracy of ultrasonography for detecting aspiration and residue published in English and Japanese until August 2019. Cross‐sectional studies, case–control studies, and cohort studies were included. The diagnostic accuracy results were extracted and the pooled estimated sensitivity and specificity were calculated. The risk of bias of the studies was assessed using the Revised Tool for the Quality Assessment of Diagnostic Accuracy Studies 2. The certainty of the evidence was assessed using the Grades of Recommendation Assessment, Development, and Evaluation methodology. Results: Five studies were included in this review. The pooled estimated sensitivity and specificity for detecting aspiration were 0.82 (95% CI: 0.72–0.89) and 0.87 (95% CI: 0.81–0.92), respectively. One study was included that evaluated ultrasound assessments of pharyngeal residue. The sensitivity and specificity were 0.62 (95% CI: 0.32–0.86) and 0.67 (95% CI: 0.22–0.96), respectively. The certainty of the evidence was low and very low for the diagnostic accuracy of aspiration and pharyngeal residue, respectively. Conclusion: Ultrasound is a non‐invasive method with good sensitivity and specificity in detecting aspiration as well as reference standards. While risk of bias and small number of studies limited the strength of this systematic review, our results suggested that ultrasound examination was useful as a bedside screening tool for detecting aspiration.

Background: Most of national schistosomiasis elimination programmes in Asia are relying on stool examination, particularly Kato Katz stool examination technique for regular transmission monitoring. However, the Kato-Katz technique has shown low sensitivity for the detection of light-intensity infections, and therefore highly sensitive diagnostic tools are urgently required to monitor prevalence of infection in low transmission settings. The objective of this systematic review was to evaluate and synthesize the performance of diagnostic tests for detecting Schistosoma japonicum and S. mekongi infection in people living in endemic areas. Methodology/Principal findings: We comprehensively searched these nine electronic databases and other resources until July 2019, with no language or publication limits: PubMed, EMBASE, MEDLINE, Web of Science, BIOSIS Citation Index, HTA, CINAHL PLUS, The Cochrane Library, and PsycINFO. We included original studies that assessed diagnostic performance using antibody, antigen, and molecular tests with stool examination test as a reference standard. Two reviewers independently extracted a standard set of data and assessed study quality. We estimated the pooled estimates of sensitivity and specificity for each index test. We used diagnostic odds ratio to determine the overall accuracy and hierarchical summary receiver operating characteristics (HSROC) curve to assess the index tests performance. Fifteen studies (S. japonicum [n = 13] and S. mekongi [n = 2]) testing 15,303 participants were included in the review. Five studies reported performance of enzyme-linked immunosorbent assay (ELISA), seven studies reported indirect hemagglutination assay (IHA), and four studies reported polymerase chain reaction (PCR) for detecting S. japonicum. The pooled sensitivity and specificity were 0.93 (95% CI: 0.84–0.98) and 0.40 (95% CI: 0.29–0.53) for ELISA, 0.97 (95% CI: 0.90–0.99) and 0.66 (95% CI: 0.58–0.73) for IHA, and 0.89 (95% CI: 0.71–0.96) and 0.49 (95% CI: 0.29–0.69) for PCR respectively. A global summary indicated the best performance for IHA, closely followed by ELISA. We were unable to perform meta-analysis for S. mekongi due to insufficient number of studies. Conclusions/Significance: IHA showed the highest detection accuracy for S. japonicum. Further studies are needed to determine the suitable diagnostic methods to verify the absence of transmission of S. mekongi and also to compare detection accuracy against more sensitive reference standards such as PCR. Author summary: Schistosomiasis remains a serious public health problem worldwide. Accurate diagnostic tests play a key role in control of schistosomiasis, especially in Asia where the prevalence and intensity of infection is low. As stool examination techniques, particularly the Kato-Katz technique has shown low sensitivity for the detection of light-intensity infections, highly sensitive diagnostics are urgently required to monitor prevalence of infection in low transmission settings. The purpose of this review was to assess and synthesize the performance of diagnostic tests for detecting schistosomiasis in people living in endemic areas in Asia. A comprehensive search, without any limit of language, date or types of publication, were performed for both- multiple electronic databases and other resources to identify the eligible studies. Robust analytical approaches such as diagnostic meta-analysis, HSROC curve, and diagnostic odds ratio, were used to provide more diagnostic accuracy of index tests. We assessed performance of three diagnostic tests (ELISA, IHA, and PCR) for detecting infection with S. japonicum using stool examination as a reference standard. In these meta-analyses, IHA showed the highest detection accuracy, followed by ELISA. We could not perform meta-analysis for S. mekongi due to insufficient number of studies. [ABSTRACT FROM AUTHOR]

Background: Recently, awareness of children's decision making has increased in an effort to enhance palliative care. However, the conceptual framework for decision making among children with cancer remains unclear. Aims: We clarified the decision-making process of children with cancer regarding their care, treatment, and support from family and health care professionals, and identified their needs and preferences. Design: We used metaethnography to conduct a metasynthesis of relevant studies. Data sources: We searched PubMed, EMBASE, PsycINFO, MEDLINE, and CINAHL. This report was prepared in accordance with the PRISMA statement. Results: Of the 7,237 retrieved studies, 27 met our inclusion criteria. Four themes emerged that reflected the decision-making process of children with cancer: (a) facing changes brought about by a health threat, (b) preparing for action, (c) asserting one's choice, and (d) internal and external influences. Conclusion: Children with cancer initially undergo a decision-making process. Respecting children's preferences, values, and emotions may help build trusting relationships and promote their decision-making capability. Future research should focus on children's emotions, cognition, development, and interactions with parents and health care professionals. [ABSTRACT FROM AUTHOR]
