Although the caesarean delivery (CD) rate has substantially increased, little is known about its impacts when performed in the first and second stages of labour on fetomaternal outcomes, especially among referred mothers. Thus, this study aimed to investigate the association between CDs performed during the first and second stages of labour and poor maternal and neonatal outcomes among mothers referred to tertiary centres.
This retrospective cohort study analysed medical records of mother–infant pairs from September 2020 to May 2023 in Southern Ethiopia.
We retrospectively collected data from 848 participants who underwent emergency CD on a referral basis during the study period.
The primary outcomes of interest were adverse maternal and neonatal outcomes. Data were analysed using descriptive and inferential statistics.
Of the 848 CDs, 722 (85.2%) and 126 (14.8%) were performed at the first and second stages of labour, respectively. Caesarean sections performed at the second stage were higher with nulliparity, increased maternal age, and birth weight. Compared with the first-stage CD, the second-stage CD was associated with a significantly increased risk of adverse maternal (OR 3.7, 95% CI 2.4 to 5.7) and neonatal outcomes (OR 2.0; 95% CI 1.3 to 2.9), including neonatal death.
Second-stage CDs have an increased risk of adverse maternal and neonatal outcomes. Strengthening and improving obstetric emergency surgical services and intensive neonatal care for those populations would help decrease the maternal and fetal negative consequences.
To assess diabetes knowledge and foot care practices among type 2 diabetes patients.
An institution-based cross-sectional study was undertaken from 1 January to 31 January 2021.
Eastern Ethiopia.
Randomly selected type 2 diabetes patients who were available during the data collection period were included.
Patients’ diabetes knowledge was assessed with the revised diabetes knowledge test questionnaire. Five items were used to evaluate foot self-care practices.
The study population comprised of 549 patients. About 52.5% of the patients had adequate diabetes knowledge (95% CI: 48.2% to 56.7%). Patients with an educational level of secondary school and above (adjusted OR (AOR): 2.04, 95% CI: 1.13 to 3.71), (AOR: 5.28, 95% CI: 2.28 to 12.22), and those with medium and above wealth status (AOR: 3.81, 95% CI: 2.24 to 6.47), (AOR: 3.46, 95% CI: 1.98 to 6.04), were found to have better odds of having adequate diabetes knowledge. However, those aged >55 years (AOR: 0.47, 95% CI: 0.22 to 0.99) were found to have lower odds of adequate diabetes knowledge.Of the total included patients, 20.2% (95% CI: 16.9% to 23.8%) had good foot care practices. Knowledge of the target fasting plasma glucose (AOR: 3.18, 95% CI: 1.94 to 5.22) and adequate diabetes knowledge (AOR: 3.40, 95% CI: 1.95 to 5.91) were significantly associated with good foot care practices.
According to this study, about half of individuals with type 2 diabetes have adequate levels of knowledge about the disease. In addition, only one out of every five patients has good foot care habits. Diabetes education should emphasise the significance of rigorous adherence to daily foot care practices.
The high incidences of both the developmental delay among young children and the mental health problems of their caregivers are major threats to public health in low-income and middle-income countries. Parental training interventions during early childhood have been shown to benefit early development, yet evidence on strategies to promote caregiver mental health remains limited. In addition, evidence on the optimal design of scalable interventions that integrate early child development and maternal mental health components is scarce.
We design a single-blind, factorial, cluster-randomised controlled, superiority trial that will be delivered and supervised by local agents of the All China Women’s Federation (ACWF), the nationwide, government-sponsored social protection organisation that aims to safeguard the rights and interests of women and children. We randomise 125 villages in rural China into four arms: (1) a parenting stimulation arm; (2) a caregiver mental health arm; (3) a combined parenting stimulation and caregiver mental health arm and (4) a pure control arm. Caregivers and their children (aged 6–24 months at the time of baseline data collection) are selected and invited to participate in the 12-month-long study. The parenting stimulation intervention consists of weekly, one-on-one training sessions that follow a loose adaptation of the Reach Up and Learn curriculum. The caregiver mental health intervention is comprised of fortnightly group activities based on an adaptation of the Thinking Healthy curriculum from the WHO. Primary outcomes include measures of child development and caregiver mental health. Secondary outcomes include a comprehensive set of physical, psychological and behavioural outcomes. This protocol describes the design and evaluation plan for this programme.
This study received approval from the Institutional Review Board of Stanford University (IRB Protocol #63680) and the Institutional Review Board of the Southwestern University of Finance and Economics in Chengdu, Sichuan, China. Informed oral consent will be obtained from all caregivers for their own and their child’s participation in the study. The full protocol will be publicly available in an open-access format. The study findings will be published in economics, medical and public health journals, as well as Chinese or English policy briefs.

To determine the feasibility of a definitive trial of metformin to prevent type 2 diabetes in the postnatal period in women with gestational diabetes.
A multicentre, placebo-controlled, double-blind randomised feasibility trial with qualitative evaluation.
Three inner-city UK National Health Service hospitals in London.
Pregnant women with gestational diabetes treated with medication.
2 g of metformin (intervention) or placebo (control) from delivery until 1 year postnatally.
Rates of recruitment, randomisation, follow-up, attrition and adherence to the intervention.
Preliminary estimates of glycaemic effects, qualitative exploration, acceptability of the intervention and costs.
Out of 302 eligible women, 57.9% (175/302) were recruited. We randomised 82.3% (144/175) of those recruited, with 71 women in the metformin group and 73 women in the placebo group. Of the participants remaining in the study and providing any adherence information, 54.1% (59/109) took at least 75% of the target intervention dose; the overall mean adherence was 64% (SD 33.6). Study procedures were found to be acceptable to women and healthcare professionals. An increased perceived risk of developing type 2 diabetes, or a positive experience of taking metformin during pregnancy, encouraged participation and adherence to the intervention. Barriers to adherence included disruption to the medication schedule caused by the washout periods ahead of each study visit or having insufficient daily reminders.
It is feasible to run a full-scale definitive trial on the effectiveness of metformin to prevent type 2 diabetes in women with gestational diabetes, during the early postnatal period. Adherence and engagement with the study could be improved with more regular reminders and potentially the addition of ongoing educational or peer support to reinforce messages around type 2 diabetes prevention.
This review explored the literature on the use of social media in recruiting young people, aged 13–18 years, to mental health research. It aimed to identify barriers and facilitators to recruitment and strategies to improve participation in future research.
Scoping review.
Articles published between January 2011 and February 2023 were searched for on PubMed, Scopus, Medline (via EBSCOhost) and Cochrane Library databases.
Studies that outlined social media as a recruitment method and recruited participants aged 13–18 years.
Data was extracted by two reviewers independently and cross-checked by a third reviewer. Data on study design, aims, participants, recruitment methods and findings related specifically to social media as a recruitment tool were collected.
24 journal articles met the inclusion criteria. Studies were predominantly surveys (n=13) conducted in the USA (n=16) recruiting via Facebook (n=16) and/or Instagram (n=14). Only nine of the included articles provided a summary of success and reviewed the efficacy of social media recruitment for young people in mental health research. Type of advertisement, the language used, time of day and the use of keywords were all found to be factors that may influence the success of recruitment through social media; however, as these are based on findings from a small number of studies, such potential influences require further investigation.
Social media recruitment can be a successful method for recruiting young people to mental health research. Further research is needed into recruiting socioeconomically marginalised groups using this method, as well as the effectiveness of new social media platforms.

This qualitative study aims to identify patient-reported barriers to treatment for neovascular age-related macular degeneration (nAMD) and investigate their impact on quality of life.
Using a qualitative explorative design.
Semi-structured individual or dyadic interviews were conducted with patients and their relatives.
Twenty-one patients completed the interview, with four of them having a relative present.
Gadamer’s hermeneutics guided the epistemological approach, and maximum variation sampling was employed to capture diverse patient experiences. An advisory board consisting of patients, relatives and ophthalmologists ensured the relevance of the study. Thematic analysis was conducted using NVivo software.
To investigate patient-reported barriers to the recommended treatment for nAMD and impact on quality of life.
The study included 21 patients with nAMD, with a median age of 79 years. Five themes emerged: (1) good compliance with intravitreal treatment, (2) the dual role of relatives, (3) treatment commute, (4) hospital barriers, (5) preventive health literacy.
This study highlights the resilience and adherence of patients with nAMD in Denmark to their treatment despite various barriers. While the therapy may have negative effects on their well-being, patients do not opt out of treatment. These findings underscore the importance of personalised treatment plans that provide, for example, convenient access to care and clear future agreements at the hospital. By adopting more patient-centred approaches, healthcare providers can enhance patient satisfaction and improve treatment adherence, ultimately leading to better patient outcomes and quality of life.
To compare the efficacy of a traditional cock-up splint, which supports the wrist only, with a modified splint that supports the wrist and the metacarpophalangeal (MCP) joints of the medial four digits in the treatment of carpal tunnel syndrome (CTS).
An assessor-blind randomised controlled trial.
Hospital-based hand therapy clinics.
Fifty-nine adults with mild-to-moderate CTS were randomly assigned to wear a wrist splint (control group) or an MCP splint (intervention group) for 6 weeks.
The standardised outcome measures used included grip and pinch strength, the static two-point discrimination test, Phalen’s manoeuvre test, Tinel’s sign and the Boston CTS Questionnaire.
Both groups improved significantly from splint use in some clinical features. The wrist splint and the MCP splint groups had significant improvements in lateral pinch strength (p=0.032 and p=0.002, respectively), two-point discrimination of the thumb (p=0.003 and p=0.041, respectively), two-point discrimination of the index (p=0.035 and p=0.023, respectively) and the Phalen’s manoeuvre symptoms (p=0.025 and p=0.002, respectively). The MCP splint group had additional improvements over the wrist splint group in tip pinch (p=0.012) and Palmar pinch (p=0.011) strength.
Splinting is a practical and effective intervention option for improving the symptoms of CTS. A wrist splint that incorporates the MCP joints is more effective than the traditional wrist-only splint, with long-lasting improvements that remained consistent after 6 months of the splint intervention. Using the more effective MCP splint may consequently reduce disability, facilitate return to work and lower the associated costs.
Stroke remains the second leading cause of death worldwide, a common cause of which is intracranial atherosclerotic stenosis (ICAS). Medical treatment is recommended as first-line therapy for treating ICAS, but the recurrence rate remains high. Drug-coated balloon (DCB) angioplasty has been designed to lower the risk of recurrent stenosis, holding therapeutic promise in the treatment of ICAS. However, the benefits of DCB require further evaluation.
The Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols was followed to develop this protocol. We will systematically search online databases including Cochrane Central Register of Controlled Trials, PubMed, Web of Science, EMBASE, China Biological Medicine Database, ClinicalTrials.gov and WHO ICTRP from 1 January 2011 to the date of search. This will be supplemented by a manual search of unpublished and ongoing trials to manually select articles for inclusion. Inclusion criteria are randomised or quasi-randomised clinical trials and observational studies that investigated DCB or medical treatment for patients with a symptomatic ICAS of 50%–99%. The primary outcome is short-term composite safety including death of any cause, or non-fatal stroke. Secondary outcomes include long-term death or stroke, restenosis, neurological rehabilitation, quality of life and other complications. The available data will be analysed using meta-analysis, if appropriate. The evaluation of heterogeneity and biases will be guided by the Cochrane Handbook for Systematic Reviews of Interventions.
This systematic review does not require ethical approval as all available data from eligible studies will be anonymous with no concerns regarding privacy. Our findings will be disseminated through international conferences and peer-reviewed publications. Additional data from the study are available on request to corresponding authors via email.

Background and objectiveThe COVID-19 pandemic impacted every single aspect of life. In addition to being a public health emergency, the COVID-19 outbreak impacted the mental health of individuals, especially pregnant women. This study aimed to examine the mental health status of pregnant women and also the effect of sociodemographic factors on their mental health status during COVID-19 in healthcare centers of Iran.
MethodsThis cross-sectional, analytical-descriptive study was conducted among pregnant women referring to healthcare centers in Shoushtar, Iran, in 2021. Multistage cluster sampling was used to select participants. Data were collected using the General Health Questionnaire-28 (GHQ-28). Data were analyzed using SPSS software version 22. The Pearson correlation coefficient was used to examine the association between quantitative variables. A generalized linear model (GLM) was applied to estimate the effect of independent variables on the dependent variable (mental health).
ResultsA total of 197 participants with a mean ± SD age of 27.85 ± 6.37 years took part in this study. The total mean score of mental health was estimated at 17.47±8.20. The highest mean ± SD score was, respectively, related to social dysfunction (6.63 ± 2.86), anxiety and insomnia (5.28 ± 3.53), and somatic symptoms (4.17 ± 3.27). Mental health disorder was significantly correlated with participants’ age (R = .223, P = .00), number of pregnancy (gravida) (R = .272, P = .00), number of births (para) (R = 0.272, P = .00), and number of abortions (R = .172, P = .015). About 80% of pregnant women did not reveal impaired mental health conditions or psychological distress, while 19.3% showed scores that indicate probable mental health conditions.
ConclusionSocial dysfunction was the most common mental health problem among pregnant women. It is necessary to pay more attention to the mental health status of pregnant women during a pandemic. Interventions such as practical strategies to promote social support and improve pregnant women’s mental health during pregnancy are highly important.

BackgroundIn Japan, as elsewhere, physicians meet with and receive gifts from pharmaceutical representatives (PRs). This study aimed to clarify the Japanese public perceptions of physicians’ relationships with PRs, examine the association between these perceptions and their trust in physicians, and compare the public’s and physicians’ awareness, acceptance, and perceptions of the influence of physician-PR relationships.
MethodsA cross-sectional, self-administered, anonymous, internet-panel survey was conducted involving 1,000 participants from the general public. The survey implementation was contracted to Cross Marketing Inc.
ResultsThe mean age of the 1000 participants was 44.8 years (standard deviation 18.3). Forty-eight percent were female. Many of our participants were unaware of certain physician-PR relationships. The public was more acceptable with physicians’ receiving stationery and/or medical textbooks and attending promotional drug seminars at their workplaces compared with receiving meals at restaurants. Many thought that physicians’ involvement in promotional activities influenced their prescribing habits and estimated that the majority of physicians received office stationery and meals from PRs. They were divided as to whether they would like to know about their physicians’ relationships with the industry. Factors associated with higher trust in physicians included participants being 65 years or older, having a primary care physician, being in better health, the belief that physicians’ involvement in promotional activities is acceptable, and their high estimate that physicians are not receiving gifts from PRs. Compared to the physicians, the public had lower awareness of and was more accepting of physicians’ involvement in promotional activities. Meanwhile, the public believed that physician-PR relationships influenced physicians’ prescribing habits more than the physicians themselves.
ConclusionOur survey provided insights into Japanese public perceptions of physician-pharmaceutical industry relationships and their impact on trust in physicians. Physicians should be aware of these perceptions and carefully consider how to foster appropriate relationships with the industry.

ObjectiveThe present study aims to measure the prevalence of non-disabled frailty and its associated factors among Bangladeshi older adults.
MethodsThis cross-sectional study was conducted during September and October 2021 among 1,045 Bangladeshi older adults (≥60 years). Telephone interviews, using a semi-structured questionnaire, were undertaken to collect data on participants’ characteristics and level of frailty. The non-disabled frailty was measured using the ‘Frail Non-Disabled (FiND)’ questionnaire. A multinomial logistic regression model assessed the factors associated with frailty among the participants.
ResultsAround a quarter of the participants (24.8%) were frail. The multinomial regression analysis showed that older participants aged ≥80 years (RRR = 3.23, 95% CI: 1.41–7.37) were more likely to be frail compared to participants aged 60–69 years. Likewise, the participants living in a large family with ≥4 members (RRR = 1.39, 95% CI: 1.01–1.92) were more likely to be frail compared to those living in smaller families. Also, participants having memory or concentration problems (RRR = 1.56, 95% CI: 1.12–2.17) were more likely to be frail compared to those who were not suffering from these problems. Moreover, participants whose family members were non-responsive to their day-to-day assistance (RRR = 1.47, 95% CI: 1.06–2.03) were more likely to be frail compared to those whose family members were responsive. Furthermore, participants who were feeling lonely (RRR = 1.45, 95% CI: 1.07–1.98) were more likely to be frail than their counterparts who were not feeling lonely.
ConclusionsThe findings of the present study suggest developing tailored interventions to address the burden of frailty among the older populations in Bangladesh. In particular, providing long-term care and health promotion activities can be of value in preventing frailty and reducing adverse health outcomes among this vulnerable population group.

IntroductionSeveral individuals with post-COVID-19 syndrome referred for pulmonary rehabilitation did not participate. This study aimed to explore individuals’ barriers to participating in posthospitalization COVID-19 rehabilitation.
Materials and methodsThis was a qualitative, multicenter study performed using semistructured interviews. This study included 20 individuals hospitalized for COVID-19 who refused to participate in a pulmonary rehabilitation program at a university hospital.
ResultsIndividuals reported difficulties accessing the rehabilitation center, mainly due to distance, transport costs and conditions, and lack of companions. Health problems (e.g., surgeries, pain, and mobility difficulties) and lack of time due to work, commuting, and household work were also reported. Another reported theme was not perceiving the need for rehabilitation due to feeling well. Minor themes included the need for more information about rehabilitation and a lack of interest, motivation, and medical encouragement.
ConclusionIndividuals hospitalized for COVID-19 faced several barriers to participating in a pulmonary rehabilitation program. These barriers included difficulties in accessing the rehabilitation center, health problems, lack of time, and the perception that rehabilitation was unnecessary. There is a need for actions to overcome these barriers to make the program available to a larger number of individuals.

ObjectivesThe purpose of this study was to compare the rates of secondary knee surgery for patients undergoing meniscus repair with or without concurrent anterior cruciate ligament reconstruction (ACLr).
MethodsUtilizing a large national database, patients with meniscal repair with or without concurrent arthroscopic ACLr were identified. The two cohorts were then queried for secondary surgical procedures of the knee within the following 2 years. Frequency, age distribution, rates of secondary surgery, and type of secondary procedures performed were compared.
ResultsIn total, 1,585 patients were identified: meniscus repair with ACLr was performed for 1,006 (63.5%) and isolated meniscal repair was performed for 579 (36.5%). Minimum of two year follow up was present for 487 (30.7% of the overall study population).Secondary surgery rates were not significantly different between meniscus repair with concurrent ACLr and isolated meniscus repairs with an overall mean follow up of 13 years (1.5–24 years) (10.6% vs. 13.6%, p = 0.126). For the 2 year follow up cohort, secondary surgery rates were not significantly different (19.3% vs. 25.6%, p = 0.1098). There were no differences in survivorship patterns between the two procedures, both in the larger cohort (p = 0.2016), and the cohort with minimum 2-year follow-up (p = 0.0586).
ConclusionThe current study assessed secondary surgery rates in patients undergoing meniscus repair with or without concurrent ACLr in a large patient database. Based on this data, no significant difference in rates of secondary knee surgery was identified.

BackgroundPrevious studies have found that the persistence of herpesvirus significantly increases the risk of idiopathic pulmonary fibrosis (IPF), but it is unclear whether this effect is causal. We conducted a two-sample Mendelian randomization (MR) study to evaluate the causal relationship between three herpesvirus infections and IPF.
MethodsWe used genome-wide association studies (GWAS) data from three independent datasets, including FinnGen cohort, Milieu Intérieur cohort, and 23andMe cohort, to screen for instrumental variables (IVs) of herpesvirus infection or herpesvirus-related immunoglobulin G (IgG) levels. Outcome dataset came from the largest meta-analysis of IPF susceptibility currently available.
ResultsIn the FinnGen cohort, genetically predicted Epstein-Barr virus (EBV) (OR = 1.105, 95%CI: 0.897–1.149, p = 0.815), cytomegalovirus (CMV) (OR = 1.073, 95%CI: 0.926–1.244, p = 0.302) and herpes simplex (HSV) infection (OR = 0.906, 95%CI: 0.753–1.097, p = 0.298) were not associated with the risk of IPF. In the Milieu Intérieur cohort, we found no correlations between herpesvirus-related IgG EBV nuclear antigen-1 (EBNA1) (OR = 0.968, 95%CI: 0.782–1.198, p = 0.764), EBV viral capsid antigen (VCA) (OR = 1.061, 95CI%: 0.811–1.387, p = 0.665), CMV (OR = 1.108, 95CI%: 0.944–1.314, p = 0.240), HSV-1 (OR = 1.154, 95%CI: 0.684–1.945, p = 0.592) and HSV-2 (OR = 0.915, 95%CI: 0.793–1.056, p = 0.225) and IPF risk. Moreover, in the 23andMe cohort, no evidence of associations between mononucleosis (OR = 1.042, 95%CI: 0.709–1.532, p = 0.832) and cold scores (OR = 0.906, 95%CI: 0.603–1.362, p = 0.635) and IPF were found. Sensitivity analysis confirmed the robustness of our results.
ConclusionsThis study provides preliminary evidence that EBV, CMV, and HSV herpesviruses, and herpesviruses-related IgG levels, are not causally linked to IPF. Further MR analysis will be necessary when stronger instrument variables and GWAS with larger sample sizes become available.

Inhaled corticosteroids are known to be relatively safe for long-term use in inflammatory respiratory diseases and it has been repurposed as one of the potential therapies for outpatients with coronavirus disease 2019 (COVID-19). However, inhaled corticosteroids have not been accepted for COVID-19 as a standard therapy because of its lack of proven benefits. Therefore, this study aimed to evaluate the effectiveness of inhaled corticosteroids in patients with COVID-19. Randomized controlled trials comparing the efficacy of inhaled corticosteroid treatment in patients with COVID-19 were identified through literature electronic database searches up to March 10, 2023. Meta-analyses were conducted for predefined outcomes, and the certainty of evidence was graded using the grading of recommendations, assessment, development, and evaluation approach. Overall, seven trials (eight articles) were included in this systematic review. Compared with usual care, inhaled corticosteroids was associated with significantly improved clinical recovery at 7 and 14 days in patients with COVID-19. In subgroup analysis, only budesonide showed significant efficacy in clinical recovery, whereas no significant benefit was observed for ciclesonide. Moreover, inhaled corticosteroids use was not significantly associated with all-cause hospitalization, all-cause mortality, admission to intensive care unit, or the use of mechanical ventilation. Our systematic review used evidence with very low to moderate certainty. Although based on limited evidence, our results suggest that inhaled corticosteroids treatment, especially budesonide, improves the clinical recovery of patients with COVID-19. More trials and meta-analyses are needed to assess the efficacy of inhaled corticosteroids for COVID-19 treatment.

BackgroundTimely referral for advanced therapies (i.e., heart transplantation, left ventricular assist device) is critical for ensuring optimal outcomes for heart failure patients. Using electronic health records, our goal was to use data from a single hospitalization to develop an interpretable clinical decision-making system for predicting the need for advanced therapies at the subsequent hospitalization.
MethodsMichigan Medicine heart failure patients from 2013–2021 with a left ventricular ejection fraction ≤ 35% and at least two heart failure hospitalizations within one year were used to train an interpretable machine learning model constructed using fuzzy logic and tropical geometry. Clinical knowledge was used to initialize the model. The performance and robustness of the model were evaluated with the mean and standard deviation of the area under the receiver operating curve (AUC), the area under the precision-recall curve (AUPRC), and the F1 score of the ensemble. We inferred membership functions from the model for continuous clinical variables, extracted decision rules, and then evaluated their relative importance.
ResultsThe model was trained and validated using data from 557 heart failure hospitalizations from 300 patients, of whom 193 received advanced therapies. The mean (standard deviation) of AUC, AUPRC, and F1 scores of the proposed model initialized with clinical knowledge was 0.747 (0.080), 0.642 (0.080), and 0.569 (0.067), respectively, showing superior predictive performance or increased interpretability over other machine learning methods. The model learned critical risk factors predicting the need for advanced therapies in the subsequent hospitalization. Furthermore, our model displayed transparent rule sets composed of these critical concepts to justify the prediction.
ConclusionThese results demonstrate the ability to successfully predict the need for advanced heart failure therapies by generating transparent and accessible clinical rules although further research is needed to prospectively validate the risk factors identified by the model.

Vinyasa yoga is moderate-intensity physical activity, yet physiological responses are poorly characterized. The purpose of this study was to examine the effect of a vinyasa yoga session on autonomic/cardiovascular functioning in healthy adults. A randomized crossover design took place at the Physical Activity and Weight Management laboratory (Pittsburgh, PA; n = 18), and included two experimental conditions: 60 minutes of vinyasa yoga or a seated control, and measurements were taken at baseline, 5-minutes, and 65-minute post-conditions. The primary cardiovascular-related outcomes of this study included blood pressure (BP), heart rate (HR), and HR variability (HRV) measures [natural log transformed (ln) standard deviation of normal-to-normal R-R intervals (SDNN), root mean square of successive differences (RMSSD), high frequency (HF), and low frequency to high frequency ratio (LF/HF ratio)]. Linear mixed effects models were used for data analyses. Systolic BP was 8.14 mmHg lower at 5 minutes post yoga (p

BackgroundEarly initiation of breastfeeding (EIBF) is key to reducing neonatal morbidity and mortality, however, little is known about the determinants of the trends of EIBF prevalence in Indonesia. This study aims to assess the contributing factors to the changes in the prevalence of EIBF between 2007 and 2017.
MethodsWe analysed data from the 2007, 2012, and 2017 Indonesia Demographic and Health Surveys to estimate the trends in EIBF. A multivariate logistic decomposition model was fitted to examine variables associated with changes in the percentage of EIBF from 2007 to 2017. The contributing factors to changes in EIBF prevalence were categorized into either compositional or behavioural changes, with each of them divided into portions or percentages of contribution (pct) of the independent variables. The former refers to the changes in the distribution of samples, while the latter refers to the changes in the behavioural responses toward EIBF in both surveys. All analyses accounted for the complex study design and potential confounding factors.
ResultsAn increase in the prevalence of EIBF from 49.9% to 56.5% was recorded between 2012 and 2017, with an overall increase of 16.9 percentage points from 2007 to 2017. At the aggregate level, the compositional differences did not significantly contribute to the changes in the percentage of EIBF, while 98.3pct (p Conclusions
Almost half of the newborns experienced delayed breastfeeding initiation despite the improvement in the prevalence of EIBF. Therefore, further research and interventions on behaviour change in mother’s attitudes towards EIBF, especially among those undergoing caesarean delivery, living in Kalimantan or Sulawesi, and from wealthier households, are recommended to close this gap.

Positive psychological well-being has a favorable impact on survival rates in both healthy and unhealthy populations. Oral health is also associated with psychological well-being, is multidimensional in nature, and includes physical, psychological, emotional, and social domains that are integral to overall health and well-being. This study aimed to identify the associations between individual and environmental characteristics, oral condition and nutritional status in relation to subjective well-being among older adults using the Wilson and Cleary conceptual model. The participants were older adults (age ≥ 60 years) attending a university hospital. Subjective well-being was assessed using the World Health Organization-5 Well-Being Index, oral condition was assessed based on the number of bacteria in the tongue coating, oral wettability, tongue pressure, occlusal force, oral diadochokinesis, and masticatory ability, and subjective swallowing function was assessed using the Eating Assessment Tool, number of remaining teeth, and number of functional teeth. In addition, factors related to well-being, including social networks, life–space mobility, nutritional status, smoking history, drinking history, and medical history were assessed. In the analysis, structural equation modeling was used to investigate the association between oral condition and subjective well-being. Confirmatory factor analysis revealed oral condition as a latent variable, including tongue pressure, oral diadochokinesis /pa/, /ta/, /ka/, occlusal force, masticatory ability, subjective swallowing function, and number of functional teeth. Structural Equation Modeling revealed that oral condition was positively correlated with nutritional status, and nutritional status was positively correlated with the World Health Organization-5 Well-Being Index. These findings suggest that oral condition may influence subjective well-being via nutritional status or social environmental factors.

From pathogen detection to genome or plasmid closure, the utility of the Oxford Nanopore Technologies (ONT) MinION for microbiological analysis has been well documented. The MinION’s small footprint, portability, and real-time analytic capability situates it well to address challenges in the field of unbiased pathogen detection, as a component of a security investigation. To this end, a multicenter evaluation of the effect of alternative analytical approaches on the outcome of MinION-based sequencing, using a set of well-characterized samples, was explored in a field-based scenario. Three expert scientific response groups evaluated known bacterial DNA extracts as part of an international first responder (Chemical, Biological, Radiological) training exercise. Samples were prepared independently for analysis using the Rapid and/or Rapid PCR sequencing kits as per the best practices of each of the participating groups. Analyses of sequence data were in turn conducted using varied approaches including ONTs What’s in my pot (WIMP) architecture and in-house computational pipelines. Microbial community composition and the ability of each approach to detect pathogens was compared. Each group demonstrated the ability to detect all species present in samples, although several organisms were detected at levels much lower than expected with some organisms even falling below 1% abundance. Several ‘contaminant’ near neighbor species were also detected, at low abundance. Regardless of the sequencing approach chosen, the observed composition of the bacterial communities diverged from the input composition in each of the analyses, although sequencing conducted using the rapid kit produced the least distortion when compared to PCR-based library preparation methods. One of the participating groups generated drastically lower sequencing output than the other groups, likely attributed to the limited computer hard drive capacity, and occasional disruption of the internet connection. These results provide further consideration for conducting unbiased pathogen identification within a field setting using MinION sequencing. However, the benefits of this approach in providing rapid results and unbiased detection must be considered along with the complexity of sample preparation and data analytics, when compared to more traditional methods. When utilized by trained scientific experts, with appropriate computational resources, the MinION sequencing device is a useful tool for field-based pathogen detection in mixed samples.
