ABSTRACT

Triage and the timing of admission of low-risk pregnant women can affect the use of augmentation, epidural, and cesarean. The purpose of this analysis was to explore these outcomes in a community hospital by the type of provider staffing triage. This was a retrospective cohort study of low-risk nulliparous women with a term, vertex fetus laboring in a community hospital. Bivariate and multivariable statistics evaluated associations between triage provider type and labor and birth outcomes. Patients in this sample (N = 335) were predominantly White (89.5%), with private insurance (77.0%), and married (71.0%) with no significant differences in these characteristics by triage provider type. Patients admitted by midwives had lower odds of oxytocin augmentation (adjusted odds ratio [aOR] = 0.50, 95% confidence interval [CI] = 0.29-0.87), epidural (aOR = 0.29, 95% CI = 0.12-0.69), and cesarean birth (aOR = 0.308, 95% CI = 0.14-0.67), compared with those triaged by physicians after controlling for patient characteristics and triage timing. This study provides additional context to midwives as labor triage providers for healthy, low-risk pregnant individuals; however, challenges persisted with measurement. More research is needed on the specific components of care during labor that support low-risk patients to avoid medical interventions and poor outcomes.

ABSTRACT

BACKGROUND: Growing evidence supports the benefits of eHealth interventions to increase patient engagement and improve outcomes for a range of conditions. However, ineffective program delivery and usage attrition limit exposure to these interventions and may reduce their effectiveness.

OBJECTIVE: This study aims to evaluate the delivery fidelity of an eHealth intervention, describe use patterns, compare outcomes between low and high users, and identify mediating factors on intervention delivery and receipt.

METHODS: This is a mixed methods study of an internet-based intervention being evaluated for effectiveness in a randomized controlled trial (RCT). The intervention comprised medication and cardiovascular disease (CVD) risk data uploaded from the primary care electronic health record (EHR); interactive, personalized CVD risk score estimation; goal setting and self-monitoring; an interactive social forum; and optional receipt of heart health messages. Fidelity was assessed over 12 months. Trial outcomes were compared between low and high users. Data sources included program delivery records, web log data, trial data, and thematic analysis of communication records.

RESULTS: Most participants in the intervention group (451/486, 93%) had an initial training session conducted by telephone (413/447, 92.4% of participants trained), with a mean duration of 44 minutes (range 10-90 minutes). Staff conducted 98.45% (1776/1804) of the expected follow-ups, mostly by telephone or email. Of the 451 participants who commenced log-ins, 46.8% (211) were categorized as low users (defined as at least one log-in in 3 or fewer months of follow-up), 40.4% (182) were categorized as high users (at least one log-in in more than 3 months of follow-up), and 12.8% (58) were nonadopters (no log-ins after their training session). The mean log-in frequency was 3-4 per month in ongoing users. There was no significant difference between the groups in the primary trial outcome of adherence to guideline-recommended medications (P=.44). In unadjusted analyses, high users had significantly greater eHealth literacy scores (P=.003) and were more likely to meet recommended weekly targets for fruit (P=.03) and fish (P=.004) servings; however, the adjusted findings were not significant. Interactive screen use was highest for goal tracking and lowest for the chat forum. Screens with EHR-derived data held only an early interest for most users. Fidelity measures (reach, content, dose delivered, and dose received) were influenced by the facilitation strategies used by staff, invisible qualities of staff-participant communication, and participants’ responsiveness to intervention attributes.

CONCLUSIONS: A multifeature internet-based intervention was delivered with high fidelity to the RCT protocol and was regularly used by 40.4% (182/451) of users over 12 months. Higher log-in frequency as an indicator of greater intervention exposure was not associated with statistically significant improvements in eHealth literacy scores, lifestyle changes, or clinical outcomes. Attributes of the intervention and individualized support influenced initial and ongoing use.

ABSTRACT

PURPOSE: Recurrent instability following a lateral patellar dislocation is a common indication for surgical intervention. Several surgical procedures are described in the literature to address recurrent patellar instability. Medial patellofemoral ligament (MPFL) reconstruction utilizing the quadriceps turndown technique attempts to restore medial stability. Results of the quadriceps turndown technique have previously only been reported in adult populations. The purpose of this study was to assess the safety, efficacy, and patient-reported outcomes following a quadriceps turndown MPFL reconstruction in the pediatric and adolescent population.

METHODS: Records of all patients who underwent MPFL reconstruction using a quadriceps turndown technique between 2011 and 2018 were reviewed for demographics, risk factors, complications, mechanism of injury, and concomitant procedures. Return to activities of daily living (ADLs), return to presurgery level of sport, length of bracing, and recurrent instability were assessed with the administration of the Kujala Anterior Knee Pain Score. All analyses were completed using IBM SPSS Statistics 26.

RESULTS: Thirty-six knees [14 female (39%), 22 male (61%)] from 34 patients met inclusion/exclusion criteria. The average follow-up length was 35.9±15.2 months. The average age was 16.3±1.8 years at the time of surgery. The average time for resumption of ADLs was 8.1±6.0 weeks after surgery. Ninety-four percent of patients returned to preinjury level of sport at an average of 23.6±12.0 weeks after surgery. Mean Kujala Anterior Knee Pain Score was 90.7±10.3. Female patients (P<0.001) reported significantly lower Kujala scores. Three patients (8%) experienced recurrent instability during ADLs and an additional 4 (11%) reported subjective feelings of instability only during sport or elevated activity. One knee required a return to the operating room for irrigation and debridement due to infection.

CONCLUSION: This study demonstrates that the quadriceps turndown technique for MPFL reconstruction is a safe and effective procedure for the management of recurrent patellar instability in pediatric and adolescent patients.

LEVEL OF EVIDENCE: Level III-therapeutic.

ABSTRACT

In the 1980s, a global number of 72 fatalities were reported in the UK and the USA following the application of subcutaneous immunotherapy (SCIT). This resulted in a significant limitation of SCIT use and in the search of other routes of administration, among which sublingual immunotherapy (SLIT) showed the best balance between efficacy and safety. Data from controlled studies suggest that tablets-related anaphylaxis is an uncommon event. However, in the Eudravigilance (European database of suspected adverse drug reactions from Europe) we found reports of life-threatening events or severe local reactions under SLIT increasing over the last few years. Therefore, all efforts to minimize the related risk have to be strongly encouraged.

ABSTRACT

Proteinaceous aggregates containing α-synuclein protein called Lewy bodies in the substantia nigra is a hallmark of Parkinson’s disease. The molecular mechanisms of Lewy body formation and associated neuronal loss remain largely unknown. To gain insights into proteins and pathways associated with Lewy body pathology, we performed quantitative profiling of the proteome. We analyzed substantia nigra tissue from 51 subjects arranged into three groups: cases with Lewy body pathology, Lewy body-negative controls with matching neuronal loss, and controls with no neuronal loss. Using a label-free liquid chromatography-tandem mass spectrometry (LC-MS/MS) approach, we characterized the proteome both in terms of protein abundances and peptide modifications. Statistical testing for differential abundance of the most abundant 2963 proteins, followed by pathway enrichment and Bayesian learning of the causal network structure, was performed to identify likely drivers of Lewy body formation and dopaminergic neuronal loss. The identified pathways include (1) Arp2/3 complex-mediated actin nucleation; (2) synaptic function; (3) poly(A) RNA binding; (4) basement membrane and endothelium; and (5) hydrogen peroxide metabolic process. According to the data, the endothelial/basement membrane pathway is tightly connected with both pathologies and likely to be one of the drivers of neuronal loss. The poly(A) RNA-binding proteins, including the ones relevant to other neurodegenerative disorders (e.g., TDP-43 and FUS), have a strong inverse correlation with Lewy bodies and may reflect an alternative mechanism of nigral neurodegeneration.

ABSTRACT

Background: Dental diseases are chronic, lifelong and preventable yet affect over half the world’s population. Personal oral hygiene practices and socio-economic factors contribute to oral health outcomes affecting oral health quality of life. Integrating basic oral care within community level health systems increases accessibility and availability of oral health resources.Objective: National Oral Health Survey of Rwanda (NOHSR) data were investigated for associations of socio-demographic characteristics, personal oral hygiene practices, oral health outcomes, and oral health quality of life indicators.Methods: Data were analyzed and descriptive statistics calculated. Multivariable logistic regression models were developed to assess associations between untreated caries, calculus, and pain with various independent variables (demographics and personal oral hygiene practices). Additional logistic regression models examined associations between quality of life indicators and the aforementioned independent variables as well as untreated caries and pain.Results: Those who did not use a toothbrush (62.7%), or toothpaste (70.0%), and cleaned their teeth less than once per day (55.3%) had a higher prevalence of untreated caries. Approximately one-third of those in rural areas cleaned their teeth once per day or more compared to two-thirds of those in urban areas (35.4% vs. 71.2%). Those cleaning their teeth less than once daily were estimated to have 56.0% higher odds of caries than those who cleaned their teeth once a day or more (OR = 1.56, [95% CI 1.25-1.95]). Those with secondary education or higher and those with skilled jobs demonstrated more frequent teeth cleaning and higher toothbrush and toothpaste use. Quality-of-life indicators varied significantly with untreated caries and pain.Conclusion: Socio-economic, individual, and workforce characteristics are important considerations when assessing oral health outcomes. This study investigated social demographic disparities in relation to oral health related behaviors and outcomes. This information can help guide oral health care programming in Rwanda.

ABSTRACT

AIM: The aim was to investigate the influence of distal resection margin and extent of mesorectal excision on long-term oncological outcomes.

DESIGN: Consecutive patients with upper and middle third rectal cancer from June 2006 to February 2016 were reviewed. Patients were divided into four groups depending on the distal margin considered as a surrogate marker of the extension of mesorectal excision (Q1: ≤ 10mm, Q2: 11-20mm, Q3: 21-30mm, Q4: ≥ 31mm).

MAIN OUTCOME MEASURES: Local recurrence-free survival (LRFS), disease-free survival (DFS) and overall survival (OS) were estimated. Cox regression models were used to investigate the influence of surgical and clinicopathological variables on prognosis by adjusting for confounding factors.

RESULTS: 211 patients with mid (125) and upper (86) rectal cancer underwent wide mesorectal excision. The median follow-up was 48.64 months (IQR: 28-63). 17.5% patients developed recurrence. The 5-year LRFS, DFS and OS for all patients were 93.20 %, 83.89% and 80.1%, respectively with no statistical significant differences among groups (DFS, p= 0.487; LRFS, p= 0.601; OS, p=0.468). At the multivariable analysis the recurrences and survival were associated with the quality of the mesorectum (LRFS, HR: 10.629 CI 95% 2.324-48.610; p=0.002; DFS, HR: 2.789 CI 95% 1.314-5.922; p:0.008).

CONCLUSION: A wide anatomical resection with partial mesorectal excision and shorter distal resection margin does not jeopardize the oncological outcomes.

ABSTRACT

Epilepsy is a chronic widely prevalent neurologic disorder, affecting brain functions with broad spectrum of deleterious consequences. High-mobility group box1 (HMGB1) is a nuclear non-histone protein that targets vital cell receptor of toll like receptor 4 (TLR4) and advanced glycation end products (RAGE). HMGB1 mediated TLR4/RAGE cascade has been scored as a key culprit in neuro-inflammatory signaling that critically evokes development of impaired cognition and epilepsy. The current study aimed to investigate the neuroprotective effect of pentoxifylline (PTX) on pentylenetetrazol (PTZ)-Kindling rats by its anti-inflammatory/antioxidant capacity besides its impact on memory and cognition were investigated, too. PTZ was intraperitoneally injected 35 mg/kg, every (48) hours, for 14 doses, to evoke kindling model. Phenytoin (30 mg/kg, i.p.) and PTX (60 mg/kg, i.p.) or their combination were given once daily for 27 days. PTX treatment showed a statistically significant effect on behavioral, histopathological and neurochemical analysis. PTX protected the PTZ kindling rats from epileptic seizures and improved memory and cognitive impairment through Morris water maze (MWM) test. Furthermore, PTX reversed PTZ hippocampal neuronal loss by decreasing protein expression of amyloid-β peptide (Aβ), Tau and β site-amyloid precursor protein-cleavage enzyme 1 (BACE1), associated with a marked reduction in expression of inflammatory mediators such as HMGB1, TL4, and RAGE proteins. Furthermore, PTX inhibited hippocampal apoptotic caspase 1 protein, total reactive oxygen species (TROS) along with upregulated erythroid 2-related factor 2 (Nrf2) content. In conclusion, PTX or its combination with phenytoin represent a promising drug to inhibit the epilepsy progression via targeting HMGB1/TLR4/RAGE signaling pathway.

ABSTRACT

In the present study, the spatial-temporal variations of iron, lead, copper, cadmium, mercury, nickel, and zinc accumulations in the water of Şehriban Stream (northern Turkey) were investigated. Water Quality Index (WQI), Heavy Metal Evaluation Index (HEI), Pearson Correlation Index (PCI), and Factor Analysis (FA) were used in analyzing the water quality. Sampling was performed in 12 stations on monthly basis between February 2019 and January 2020 (a hydrological year). The data showed that the Şehriban Stream had significantly high water quality characteristics and the investigated toxicants were not found as dangerous for health. Although there was a slight decrease in the water quality from upstream to downstream, the stream was found to have 1^st class water quality in general. As a result of WQI and HEI, although it was determined that the water quality decreased slightly in autumn, the stream was found to be “A Grade – Excellent (<50)” and “Low Contamination (<10)”, respectively. As a result of PCI, strong positive correlations were found between almost all the toxicants investigated here (p <0.01). As a result of FA, 2 factors ( “Agriculture – Forestry” and “Rock Structure”) explained 86% of the total variance.
