ABSTRACT

The ecosystem services provided by dung beetles are well known and valued. Dung beetles bury dung for feeding and breeding, and it is generally thought that the process of burying dung increases nutrient uptake by plant roots, which promotes plant growth. Many studies have tested the effects of dung beetles on plant growth, but there has been no quantitative synthesis of these studies. Here we use a multi-level meta-analysis to estimate the average effect of dung beetles on plant growth and investigate factors that moderate this effect. We identified 28 publications that investigated dung beetle effects on plant growth. Of these, 24 contained the minimum quantitative data necessary to include in a meta-analysis. Overall, we found that dung beetles increased plant growth by 17%; the 95% CI for possible values for the true increase in plant growth that were most compatible with our data, given our statistical model, ranged from 1% to 35%. We found evidence that the dung beetle-plant growth relationship is influenced by the plant measurement type and the number of beetles accessing the dung. However, beetles did not increase plant growth in all quantitative trials, as individual effect sizes ranged from -72% to 806%, suggesting important context-dependence in the provision of ecosystem services.

ABSTRACT

BACKGROUND: Exclusive breastfeeding (BF) has the greatest potential impact on child mortality of any preventive intervention. Skin-to-skin contact (SSC) during the first hour of life is beneficial for initiating BF; however, routine separation of mother and infant is still common. This work aimed to demonstrate that SSC during the first hour of life is associated with a greater frequency and duration of exclusive BF.

METHODS: This is an observational case-control study. We reviewed the medical records of patients born between 2016 and 2022 classified as cases or controls based on the history of SSC in the first hour of life. Statistical analysis was performed using SPSS version 28.

RESULTS: We included 362 medical records, of which 200 (55.2%) had SSC and were considered cases; the 162 (44.8%) who did not have SSC were considered controls. Those who received SSC were more likely to receive exclusive BF at 3 (163 [81.5%] vs. 94 [58%], p < 0.001) and 6 months of age (147 [73.5%] vs. 83 [51.2%], p < 0.001).

CONCLUSIONS: Patients who received SSC in the first hour of life were more likely to receive exclusive BF at 3 and 6 months of age. Promoting and respecting this practice is essential to increase the possibility of a newborn to be exclusively breastfed for the first 6 months of life.

ABSTRACT

BACKGROUND: With the identification of COVID-19 disease in China, a pandemic began that affected health-care systems. The Neonatal Intensive Care Unit (NICU) of the Hospital de Ginecobstetricia del Centro Médico Nacional de Occidente experienced an increase in patient flow as part of the COVID-19 strategy of the Instituto Mexicano del Seguro Social (IMSS). This study aimed to analyze the impact of the COVID-19 pandemic on neonatal care and mortality indicators in our unit.

METHODS: We conducted a retrospective study to compare the number of hospital births, pre-term newborns (PTNB), NICU admissions, and deaths. Changes in frequencies between 2019 and 2021 were analyzed using Poisson distribution. Changes in PTNB births, proportion of admissions, and deaths/NICU discharges were analyzed by z-test for two proportions.

RESULTS: Between 2019 and 2021, the number of births increased by more than 2-fold. NICU admissions increased from 770 in 2019 to 1045 in 2021 (p < 0.01). The ratio of deaths/discharge from the service was 16.9% in 2019 and 13.1% in 2021 (p = 0.02).

CONCLUSIONS: Mortality indicators in the NICU decreased from 2019 to 2021, even with the increase in the number of patients admitted during the COVID-19 pandemic.

ABSTRACT

OBJECTIVE: This study aimed to evaluate fetal epicardial fat thickness (EFT) together with fetal myocardial performance index (MPI) and its effects on neonatal outcomes in obese pregnant women.

MATERIALS AND METHODS: A total of 102 pregnant women, 51 obese and 51 of normal weight, were included in this prospective study. Fetal EFT, and MPI measurements were performed for all patients.

RESULTS: Fetal EFT and Mod-MPI showed a statistically significant difference between obese pregnant women and the control group (p=0.0001, p=0.001). The optimal fetal EFT predictive cut-off value for the 5th-minute APGAR score below 7 was 1.22 mm, with a sensitivity of 86.96% and a specificity of 54.43% (p=0.001).

CONCLUSION: Fetal EFT and mod-MPI were higher in obese pregnant women. It is encouraging that fetal EFT predicts low APGAR, but more important information can be obtained if postnatal follow-up of these cardiac changes caused by obesity can be performed.

ABSTRACT

BACKGROUND: Cold resection of colorectal lesions is widely performed because of its safety and effectiveness; however, it remains uncertain whether adding submucosal injection could improve the efficacy and safety. We aimed to compare cold endoscopic mucosal resection (C-EMR) versus cold snare polypectomy (CSP) for colorectal lesions.

METHODS: We performed a systematic review of randomized controlled trials (RCTs) identified from PubMed, Cochrane Library, and Embase. The primary outcome was complete resection. Secondary outcomes were procedure time, en bloc resection, and adverse events (AEs). Prespecified subgroup analyses based on the size and morphology of the polyps were performed. The random-effects model was used to calculate the pooled risk ratio (RR) and mean difference, with corresponding 95%CIs, for dichotomous and continuous variables, respectively. Heterogeneity was assessed using the Cochran Q test and I ² statistics.

RESULTS: 7 RCTs were included, comprising 1556 patients, with 2287 polyps analyzed. C-EMR and CSP had similar risk ratios for complete resection (RR 1.02, 95%CI 0.98-1.07), en bloc resection (RR 1.08, 95%CI 0.82-1.41), and AEs (RR 0.74, 95%CI 0.41-1.32). C-EMR had a longer procedure time (mean difference 42.1 seconds, 95%CI 14.5-69.7 seconds). In stratified subgroup analyses, the risk was not statistically different between C-EMR and CSP for complete resection in polyps<10 mm or ≥10 mm, or for complete resection, en bloc resection, and AEs in the two groups among nonpedunculated polyps.

CONCLUSIONS: The findings of this meta-analysis suggest that C-EMR has similar efficacy and safety to CSP, but significantly increases the procedure time.

ABSTRACT

OBJECTIVE: The objective of the study is to evaluate the safety and efficacy of three different treatment methods for pediatric ulnar and radial double fractures.

METHODS: 120 children with ulnar and radial double fractures were included in the study. According to the different treatment plans, children were divided into three groups: manual reduction, splint external fixation, double elastic intramedullary fixation, and double plate fixation. Surgical indicators, radiological results, clinical efficacy, and complications were evaluated and compared among the groups.

RESULTS: The average hospital stay and operation time were significantly longer in the double plate internal fixation group compared to the other two groups. The double elastic intramedullary nailing group showed a higher fracture healing rate at 3 months compared to the other groups. There were no significant differences in clinical efficacy among the three groups. Complications were observed in all groups but did not show significant statistical differences.

CONCLUSION: Double elastic intramedullary nailing fixation demonstrated favorable outcomes in terms of surgical indicators and fracture healing rates for pediatric ulnar and radial double fractures.

ABSTRACT

BACKGROUND: Steatotic liver disease (SLD) prevalence is rising worldwide, linked to insulin resistance and obesity. SLD prevalence can surpass 10% even among those with normal weight. In Lao People’s Democratic Republic (Lao PDR), where Opisthorchis viverrini (OV) trematode infection and type 2 diabetes mellitus (T2DM) are common, infection related liver morbidity such as cholangiocarcinoma (CCA) is high, but data on SLD prevalence is lacking. The objective of this study was to estimate the prevalence and explore determinants of SLD in rural southern Lao PDR for lean and non-lean populations.

METHOD: A cross-sectional community-based study assessed SLD prevalence using abdominal ultrasonography (US). Factors investigated for association with SLD were identified by interview, serological tests (Hepatitis B surface antigen (HBsAg); lipids and HbA1c), anthropometrical measurements, and parasitological assessments (OV infection). Uni- and multivariable logistic regression analyses with SLD as endpoint were conducted separately for lean (body mass index (BMI) <23.0 kg/m²) and non-lean (BMI ≥ 23.0 kg/m²) participants.

RESULT: 2,826 participants were included. SLD prevalence was 27.1% (95% confidence interval (95% CI) 24.0%-30.4%), higher among non-lean (39.8%) than lean individuals (17.4%). Lean individuals with OV infection had a statistically significant association with lower odds of SLD (adjusted odds ratio (aOR) 0.49, 95% CI 0.33 – 0.73). T2DM showed a significant positive association with SLD in both lean (aOR 3.58, 95% CI 2.28 – 5.63) and non-lean individuals (aOR 3.31, 95% CI 2.31 – 4.74) while dyslipidemia was significantly associated only in the non-lean group (aOR 1.83, 95% CI 1.09 – 3.07). Females participants exhibited elevated odds of SLD in both lean (aOR 1.43, 95% CI 1.02 – 2.01) and non-lean SLD (aOR 1.50, 95% CI 1.12 – 2.01).

CONCLUSION: SLD prevalence is notably high among Laotian adults in rural areas, particularly in females and in non-lean individuals. Lean individuals with OV infection exhibited lower SLD prevalence. SLD was more prevalent in individuals with T2DM, independent of BMI. SLD adds to the burden of infection-related liver morbidity in Lao PDR.

ABSTRACT

BACKGROUND: Lumbar disc herniation (LDH), as one of the most common causes of lower back pain, imposes a heavy economic burden on patients and society. Conservative management is the first-line choice for the majority of LDH patients. Traditional Chinese medicine (TCM) is an important part of conservative treatment and has attracted more and more international attention.

STUDY DESIGN: Evidence-based guideline.

METHODS: We formed a guideline panel of multidisciplinary experts. The clinical questions were identified on the basis of a systematic literature search and a consensus meeting. We searched the literature for direct evidence on the management of LDH and assessed its certainty-generated recommendations using the grading of recommendations, assessment, development, and evaluation (GRADE) approach.

RESULTS: The guideline panel made 20 recommendations, which covered the use of Shentong Zhuyu decoction, Shenzhuo decoction, Simiao San decoction, Duhuo Jisheng decoction, Yaobitong capsule, Yaotongning capsule, Osteoking, manual therapy, needle knife, manual acupuncture, electroacupuncture, Chinese exercise techniques (Tai Chi, Baduanjin, or Yijinjing), and integrative medicine, such as combined non-steroidal anti-inflammatory drugs, neural nutrition, and traction. Recommendations were either strong or weak, or in the form of ungraded consensus-based statement.

CONCLUSION: This is the first LDH treatment guideline for TCM and integrative medicine with a systematic search, synthesis of evidence, and using the GRADE method to rate the quality of evidence. We hope these recommendations can help support healthcare workers caring for LDH patients.

ABSTRACT

OBJECTIVE: Time-varying treatments are common in observational studies. However, when assessing treatment effects, the methodological framework has not been systematically established for handling time-varying treatments. This study aimed to examine the current methods for dealing with time-varying treatments in observational studies and developed practical recommendations.

METHODS: We searched PubMed from 2000 to 2021 for methodological articles about time-varying treatments, and qualitatively summarized the current methods for handling time-varying treatments. Subsequently, we developed practical recommendations through interactive internal group discussions and consensus by a panel of external experts.

RESULTS: Of the 36 eligible reports (22 methodological reviews, 10 original studies, 2 tutorials and 2 commentaries), most examined statistical methods for time-varying treatments, and only a few discussed the overarching methodological process. Generally, there were three methodological components to handle time-varying treatments. These included the specification of treatment which may be categorized as three scenarios (i.e., time-independent treatment, static treatment regime, or dynamic treatment regime); definition of treatment status which could involve three approaches (i.e., intention-to-treat, per-protocol, or as-treated approach); and selection of analytic methods. Based on the review results, a methodological workflow and a set of practical recommendations were proposed through two consensus meetings.

CONCLUSIONS: There is no consensus process for assessing treatment effects in observational studies with time-varying treatments. Previous efforts were dedicated to developing statistical methods. Our study proposed a stepwise workflow with practical recommendations to assist the practice.

ABSTRACT

Background: Noma is a gangrenous infection of the face that results in severe facial deformity, occurring primarily in malnourished and impoverished populations. Objective: To assess clinician- and patient-reported outcomes (PROs) before and after reconstructive surgery for patients with noma in northwest Nigeria. Methods: Objective outcomes were recorded using the noma-specific NOITULP (nose, outer cheek, inner cheek, trismus, upper/lower lip, particularities) classification system. PROs were recorded using a locally developed tool. Postsurgical changes were assessed by Wilcoxon signed-rank testing. Linear regression was used to look for associated risk factors. The inter-rater reliability (IRR) of the NOITULP score was assessed using the weighted kappa statistic. Results: Forty-nine patients (median age 25 years, 71% male) underwent local/regional flap reconstruction and/or trismus release. Twelve complications were reported. Univariate analysis showed a 3.20 change in PRO score (95% confidence interval 0.59 to 5.81, p = 0.018) per kilogram the patient underwent at time of surgery. The NOITULP score improved from a presurgery median of 3.5 to 2.3 (p < 0.0001), however, the IRR was poor (kappa = 0.0894, p < 0.0001). The PRO score also improved from a median of 7.0 to 12.0 (p < 0.0001). Conclusions: Facial reconstructive surgery improves the NOITULP score and PROs in patients with noma in northwest Nigeria. Clinical Trial Registration: OCA017-63.
