ABSTRACT

We studied the effects of mother-infant interaction and maternal pre- and postnatal psychological distress on children’s social-emotional problems and competences, as well as whether interaction quality moderates the association between distress and children’s outcomes. Maternal pre- and postnatal psychological distress were measured using the SCL and EPDS questionnaires, whereas mother-infant interaction was measured when the child was 8 months old using the EA Scales. Children’s social-emotional development was measured using the BITSEA questionnaire at 2 years old and using the SDQ questionnaire at 4 years old, where higher maternal structuring was associated with fewer social-emotional problems in children and higher maternal sensitivity was associated with greater social-emotional competence in children at 2 years old. Further, higher postnatal distress was found associated with greater social-emotional problems at 2 years old, though neither these effects nor moderating effects at 4 years old were observed after multiple-comparison corrections. Our findings support direct associations of both mother-infant interaction and maternal postnatal psychological distress with children’s social-emotional development during toddlerhood.

ABSTRACT

Mathematical modelling applied to preclinical, clinical, and public health research is critical for our understanding of a multitude of biological principles. Biology is fundamentally heterogeneous, and mathematical modelling must meet the challenge of variability head on to ensure the principles of diversity, equity, and inclusion (DEI) are integrated into quantitative analyses. Here we provide a follow-up perspective on the DEI plenary session held at the 2023 Society for Mathematical Biology Annual Meeting to discuss key issues for the increased integration of DEI in mathematical modelling in biology.

ABSTRACT

Individuals experiencing chronic homelessness have high rates of persistent co-occurring mental health and substance use disorders (COD), and they often have difficulty with service engagement and retention, resulting in symptom exacerbation and housing loss. This study pilot tested Maintaining Independence and Sobriety Through Systems Integration, Outreach and Networking (MISSION), a multicomponent wraparound treatment approach to improve COD symptoms and housing stability among individuals experiencing chronic homelessness and persistent COD. This open pilot study enrolled and assessed 109 individuals with a COD experiencing chronic homelessness and offered one year of MISSION. Statistically significant improvements were observed in behavioral health symptoms and functioning, days of illicit drug use, and housing stability. By treatment completion, 85% of participants were referred to social and behavioral supports. This pilot study demonstrates that MISSION helped to successfully engage participants in treatment, reduce substance use and mental health symptoms, and improve housing outcomes.

ABSTRACT

INTRODUCTION: Pseudobulbar palsy is a common symptom in patients with amyotrophic lateral sclerosis (ALS), but it is often underdiagnosed or misdiagnosed as other diseases. The Center for Neurologic Study Lability Scale (CNS-LS) is a self-report scale consisting of seven questions designed for evaluating pseudobulbar affect (PBA). The current study aimed to validate a Chinese version of the CNS-LS.

METHODS: The Chinese version of the CNS-LS was obtained through a standardized forward-backward translation and cultural adaptation. A total of 105 patients with ALS were recruited from the ALS database of Peking University Third Hospital in Beijing, China, to complete the CNS-LS. The reliability of the Chinese version was determined by the test-retest method, and receiver operating characteristic (ROC) analysis was performed for criterion validity.

RESULTS: Of 105 patients with ALS, 37 had symptoms of PBA and were diagnosed with that condition by neurologists. Forty-two patients completed the CNS-LS twice, and there was no statistically significant difference between the scores (Z = -0.896, p = 0.37). The Spearman correlation coefficient between the test and retest scores was 0.940 (p < 0.0005), and the Cronbach alpha coefficient was high (α = 0.905, n = 105). Scores of 12 or higher on the CNS-LS identified PBA with sensitivity of 0.919 and specificity of 0.882. The area under the ROC curve was 0.924.

CONCLUSION: The Chinese version of the CNS-LS demonstrated good sensitivity and specificity in the group of patients with ALS enrolled in this study. The CNS-LS should be a useful instrument for clinical and research purposes for patients in this language group.

ABSTRACT

This study sought to evaluate the impact of severe obesity on image quality and ventricular function assessment in cardiovascular magnetic resonance (MRI) and trans-thoracic echocardiography (TTE). We studied 100 consecutive patients who underwent clinically indicated cardiac MRI and TTE studies within 12 months between July 2017 and December 2020; 50 (28 females and 22 males; 54.5 ± 18.7 years) with normal body mass index (BMI) (18.5-25 kg/m²) and 50 (21 females and 29 males; 47.2 ± 13.3 years) with severe obesity (BMI ≥ 40 kg/m²). MRI and TTE image quality scores were compared within and across cohorts using a linear mixed model. Categorical left (LVF) and right (RVF) ventricular function were compared using Cohens Kappa statistic. Mean BMI for normal weight and obese cohorts were 22.2 ± 1.7 kg/m² and 50.3 ± 5.9 kg/m², respectively. Out of a possible 93 points, mean MRI image quality score was 91.5 ± 2.5 for patients with normal BMI, and 88.4 ± 5.5 for patients with severe obesity; least square (LS) mean difference 3.1, p = 0.460. TTE scores were 64.2 ± 13.6 for patients with normal BMI and 46.0 ± 12.9 for patients with severe obesity, LS mean difference 18.2, p < 0.001. Ventricular function agreement between modalities was worse in the obese cohort for both LVF (72% vs 80% agreement; kappa 0.53 vs 0.70, obese vs. normal BMI), and RVF (58% vs 72% agreement, kappa 0.18 vs 0.34, obese vs. normal BMI). Severe obesity had limited impact on cardiac MRI image quality, while obesity significantly degraded TTE image quality and ventricular function agreement with MRI.

ABSTRACT

To effectively control and eradicate PPR, the comprehensive understanding of risk factors associated with PPR exposure is vital. Hence, this study investigated socioeconomic and other associated risk determinants for PPR exposure at flock level in sheep and goats in a non-vaccination programme implemented Madhya Pradesh state India. A total of 410 sheep and goat flocks, comprised mostly of goats but also some mixed flocks, were surveyed during 2016 using a multistage random sampling procedure. Further, 230 blood samples were also collected from the farmers-reported PPR affected flocks and sera were tested using c-ELISA to confirm PPR exposure. The primary data on socioeconomic factors, farm management factors, health status, vaccination details and other epidemiological risk factors were collected from flock owners and descriptive statistics, chi-square analysis and logistic regression models were fitted to identify the significant risk factors for PPR incidence. The farmer’s education, flock size, rearing pattern, and awareness of PPR vaccination were found to be significant pre-disposing risk factors for PPR exposure in the flocks. Hence, the control and eradication strategy need to be designed comprehensively considering the key social factors like education and vaccination awareness along with other flock level risk factors to eradicate PPR by 2030 in consonance with the global plan.

ABSTRACT

PURPOSE: Osteoporotic individuals who have dental implants usually require a prolonged healing time for osseointegration due to the shortage of bone mass and the lack of initial stability. Although studies have shown that intermittent teriparatide administration can promote osseointegration, there is little data to support the idea that pre-implantation administration is necessary and beneficial.

METHODS: Sixty-four titanium implants were placed in the bilateral proximal tibial metaphysis in 32 female SD rats. Bilateral ovariectomy (OVX) was used to induce osteoporosis. Four major groups (n = 8) were created: PRE (OVX + pre-implantation teriparatide administration), POST (OVX + post-implantation administration), OP (OVX + normal saline (NS)) and SHAM (sham rats + NS). Half of rats (n = 4) in each group were euthanized respectively at 4 weeks or 8 weeks after implantation surgery, and four major groups were divided into eight subgroups (PRE4 to SHAM8). Tibiae were collected for micro-CT morphometry, biomechanical test and undecalcified sections analysis.

RESULTS: Compared to OP group, rats in PRE and SHAM groups had a higher value of insertion torque (p < 0.05). The micro-CT analysis, biomechanical test, and histological data showed that peri-implant trabecular growth, implants fixation and bone-implant contact (BIC) were increased after 4 or 8 weeks of teriparatide treatment (p < 0.05). There was no statistically difference in those parameters between PRE4 and POST8 subgroups (p > 0.05).

CONCLUSIONS: In osteoporotic rats, post-implantation administration of teriparatide enhanced peri-implant bone formation and this effect was stronger as the medicine was taken longer. Pre-implantation teriparatide treatment improved primary implant stability and accelerated the osseointegration process.

ABSTRACT

PURPOSE: This study compared the recovery of motor function and the safety of early and delayed surgical intervention in patients with central cord syndrome (CCS).

METHODS: PubMed, Embase, Cochrane Library, and Web of Science were employed to retrieve the targeted studies published from inception to February 19, 2023. Comparative studies of early versus delayed surgical decompression in CCS based on American Spinal Injury Association motor score (AMS) recovery, complication rates, and mortality were selected. The statistical analyses were performed using STATA 16.0 and RevMan 5.4.

RESULTS: Our meta-analysis included 13 studies comprising 8424 patients. Results revealed that early surgery improved AMS scores significantly compared with delayed surgery, with an increase in MDs by 7.22 points (95% CI 1.98-12.45; P = 0.007). Additionally, early surgery reduced the complication rates than delayed surgery (OR 0.53, 95% CI 0.42-0.67, P < 0.00001). However, no significant difference was observed in mortality between the two groups (OR 0.97; 95% CI 0.75-1.26; P = 0.84).

CONCLUSIONS: Early surgical decompression for CCS can improve motor function and reduce the incidence of complications without affecting the mortality rate in patients. Future research should focus on investigating and analyzing the optimal window period for early CCS surgery. Additionally, the timing of surgery should be determined based on the patient’s condition and available medical resources.

ABSTRACT

Burnout syndrome is characterized by the triad of symptoms exhaustion, mental distance from work activities and a feeling of ineffectiveness. The syndrome is not an independent mental disorder but can be coded in the 10th Revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) as a problem related to difficulties in coping with life (Z73) and in ICD-11 as a qualifying diagnosis (QD85). This article discusses the prevalence and comorbidities of burnout syndrome, taking the methodological difficulties in conceptualizing and operationalizing the construct into account. In addition, it provides an overview of available measurement instruments and their validation. Furthermore, it discusses work-related and individual factors in the development of burnout syndrome as well as analysis of the effectiveness of treatment options.

ABSTRACT

PURPOSE: To evaluate literature evidences about the efficacy and safety of anti-angiogenesis agents plus chemoradiotherapy versus chemoradiotherapy in the treatment of locally advanced nasopharyngeal carcinoma.

METHODS: The relevant literature was systematically searched from the date of establishment to April 2023 in PubMed, Embase, Web of Science, The Cochrane Library, Chinese National Knowledge Infrastructure, Chinese Biological Medicine, Wanfang and VIP database. Search terms included: Nasopharyngeal Neoplasms, Angiogenesis inhibitors, Endostar, Anlotinib, Apatinib, Bevacizumab, Sunitinib, Pazopanib, Chemoradiotherapy. The literature was strictly screened according to the inclusion and exclusion criteria, and 8 eligible studies were finally included in our meta-analysis (4 randomized controlled trials and 4 retrospective studies).

RESULTS: A total of 642 patients were included, with 316 in the anti-angiogenesis agents plus chemoradiotherapy group and 326 in the chemoradiotherapy group. The results of our meta-analysis showed that compared with chemoradiotherapy group, the complete response rate (RR = 1.35, 95% CI 1.05-1.74, P = 0.02), objective response rate (RR = 1.26, 95% CI 1.12-1.43, P = 0.0002) in the anti-angiogenesis agents plus chemoradiotherapy group were significantly improved. In terms of safety, there was a higher incidence of cardiac arrhythmia (RR = 3.63, 95% CI 1.16-11.37, P = 0.03) and hypertension (RR = 1.85, 95% CI 1.04-3.27, P = 0.004) in the anti-angiogenesis agents plus chemoradiotherapy group, while no statistically significant differences were reported in other adverse reactions (all P > 0.05).

CONCLUSION: Compared with chemoradiotherapy, anti-angiogenesis agents plus chemoradiotherapy could bring more benefits in terms of short-term efficacy, particularly by notably improving both complete response rate and objective response rate, and overall adverse reactions were acceptable. Anti-angiogenesis agents plus chemoradiotherapy may provide a promising direction for the treatment of locally advanced nasopharyngeal carcinoma.
