ABSTRACT

BACKGROUND: Posterior wall acetabular fractures remain one of the most difficult fracture injuries to treat. Accurate assessment of fracture characteristics and appropriate preoperative surgical strategies are essential for excellent reduction. This paper evaluates the feasibility and effectiveness of a one-stop computerized virtual planning system for the surgical management of posterior wall acetabular fractures.

METHODS: 52 cases of posterior wall acetabular fractures treated surgically were selected in our department between January 2015 and December 2020 for retrospective analysis. 52 cases were classified into group A (25 patients) and group B (27 patients) according to whether computerized virtual planning procedures were performed preoperatively. In group A, virtual surgical simulation was conducted using a one-stop computerized planning system preoperatively. In group B, traditional surgery was employed. Reduction quality, surgical time, blood loss, hip function, complications, and instrumentation time were compared between the two groups.

RESULTS: The actual surgery for all patients in group A was essentially the same as the virtual surgery before the operation. Compared to group B, patients in group A had markedly shorter surgical time (-43 min), shorter instrumentation time (-20 min), and less intraoperative blood loss (-130 ml). However, no significant statistical difference was observed in reduction quality and hip function. The complication rate was slightly lower in group A (4/25) than in group B (7/27), without a significant difference.

CONCLUSION: The one-stop computerized virtual planning system is a highly effective, user-friendly and educational tool for allowing the cost-efficient surgical simulation of posterior wall acetabular fractures and providing a more individualized therapeutic schedule. The one-stop computerized planning system is feasible to treat posterior wall acetabular fractures, which is an effective method than the conventional treatment of posterior wall acetabular fractures.

ABSTRACT

BACKGROUND: Squamous cell carcinoma is the most common malignancy of the oral cavity. Primary treatment involves surgical resection of the tumour with a surrounding margin. Historically, the most commonly accepted margin clearance is 5 mm. This distance is controversial, with recent publications suggesting closer margins do not impact local recurrence and survival. The objective of this study is to determine the closest surgical margin that does not impact local recurrence and overall survival.

METHODS: A retrospective review of the London Health Sciences Centre Head and Neck Multidisciplinary Clinic between 2010 and 2018 was performed. Demographic data, subsite, tumour staging, treatment modality, margins, and survival outcomes were analyzed. The primary endpoint was local recurrence free survival. Secondary endpoints included recurrence-free survival and overall survival. Descriptive statistics, as well as univariable and multivariable Cox proportional hazards regression modelling were performed for all patients.

RESULTS: Four-hundred and twelve patients were included in the study, with a median follow-up of 3.3 years. On univariable analysis, positive margins and margins < 1 mm were associated with significantly worse local recurrence-free survival, recurrence-free survival, and overall survival (p < 0.05), compared to margins > 5 mm. Patients with surgical margins > 1 mm experienced similar outcomes to those with margins > 5 mm. Multivariable analysis identified age of diagnosis, alcohol consumption, pathological tumour and nodal category as predictors of local recurrence free survival.

CONCLUSIONS: Although historical margins for head and neck surgery are 5 mm, similar outcomes were observed for margins greater than 1 mm in our cohort. These findings require validation through multi-institutional collaborative efforts.

ABSTRACT

BACKGROUND: Creating an environment for emotional and social well-being is an important responsibility of Health-Promoting and Child-Friendly Schools. Thus, the present study aimed to assess cultural adaptation and validation of the Persian version of the Psycho-Social Environment (PSE) Profile. The second purpose of this study was to survey the psycho-social environment of schools among a local sample of Iranian school staff.

METHODS: This study was conducted in two phases, including cultural adaptation and validation of a culturally adapted scale. The cultural adaptation process followed the procedure suggested by Beaton et al. Then, the culturally adapted scale was administered to a local sample of Iranian school staff including managers (21.9%), teachers (57.4%), support staff (4%), and other school staff (16.7%) in a cross-sectional study. The participants’ mean age was 39.98 ± 8.11 years and they were mostly female (62.8%). The psychometric properties of the culturally adapted version of the questionnaire were tested using a confirmatory factor analysis (n = 265), and a test of internal consistency. Finally, the status of schools’ psycho-social environment was assessed using descriptive and analytical statistics.

RESULTS: Confirmatory factor analysis indicated an overall good fit for the 7-factor profile (χ2/df: 1.906, PNFI: 0.62, TLI: 0.78, CFI: 0.79, RMSE: 0.059). The test of internal consistency showed an acceptable reliability (α = 0. 98).

CONCLUSIONS: The Persian version of the PSE profile was culturally adapted for use in Iranian schools. Certainly, this culturally adapted version of PSE profile could be useful to determine the school psycho-social environment and to make any changes that can promote a friendly school climate for all participants, and to enhance learning and development.

ABSTRACT

BACKGROUND: Person-centered maternity care is respectful and responsive care to individual women’s preferences, needs, and values and ensuring that their values guide all clinical decisions during childbirth. It is recognized as a key dimension of the quality of maternity care that increases client satisfaction and institutional delivery. However, little research has been conducted about person-centered maternity care in Ethiopia.

OBJECTIVE: The aim of this study was to assess the status of person-centered maternity care and associated factors among mothers who gave birth at selected public hospitals in Addis Ababa city, Addis Ababa, Ethiopia, 2021.

METHOD: A facility-based cross-sectional study was conducted at selected public hospitals in Addis Ababa city. A structured questionnaire was used to collect data from post-natal mothers selected by systematic random sampling. Data were collected using face-to-face interview technique. The data was coded and entered using Epi-data version 4.6 and analyzed using SPSS version 25. Bivariate and multivariable linear regression analysis was used to identify factors associated with person-centered maternity care. The strength of association between independent and dependent variables was reported by using unstandardized β at 95% CI and p-value < 0.05 were considered statistically significant.

RESULTS: In this study 384 mothers were participated with a response rate of 99.2%. The overall prevalence of person-centered maternity care was 65.8% and the percentage mean Person Centered Maternity Care (PCMC) score of the respondents was 65.8% with percentage standard deviation of 17.06. Respondents who had no ANC follow-up (β = -5.39, 95% CI: -10.52, -0.26), < 4 Antenatal Care (ANC) follow up (β = -3.99, 95% CI: -6.63, -1.36), night time delivery (β = -3.95, 95% CI: -5.91, -1.98) and complications during delivery (β = -3.18, 95% CI: -6.01, -0.35) were factors significantly associated with person-centered maternity care.

CONCLUSION AND RECOMMENDATIONS: The finding of this study showed that the proportion of person-centered maternity care among mothers who gave birth in public hospitals of Addis Ababa was high as compared to previous studies. The factors affecting person-centered maternity care are manageable to interventions. Therefore, Policymakers should develop and implement guidelines about person-centered maternity care. Training should be given to health care providers on the importance of person-centered maternity care and patient and provider rights. Hospital managers should increase the number of staffs who got PCMC training, especially during nighttime to improve the provision of person-centered maternity care. Health care providers should implement person-centered maternity care for all mothers who gave birth in the health care facility.

ABSTRACT

BACKGROUND: Hormonal changes during the menstrual cycle play a key role in shaping immunity in the cervicovaginal tract. Cervicovaginal fluid contains cytokines, chemokines, immunoglobulins, and other immune mediators. Many studies have shown that the concentrations of these immune mediators change throughout the menstrual cycle, but the studies have often shown inconsistent results. Our understanding of immunological correlates of the menstrual cycle remains limited and could be improved by meta-analysis of the available evidence.

METHODS: We performed a systematic review and meta-analysis of cervicovaginal immune mediator concentrations throughout the menstrual cycle using individual participant data. Study eligibility included strict definitions of the cycle phase (by progesterone or days since the last menstrual period) and no use of hormonal contraception or intrauterine devices. We performed random-effects meta-analyses using inverse-variance pooling to estimate concentration differences between the follicular and luteal phases. In addition, we performed a new laboratory study, measuring select immune mediators in cervicovaginal lavage samples.

RESULTS: We screened 1570 abstracts and identified 71 eligible studies. We analyzed data from 31 studies, encompassing 39,589 concentration measurements of 77 immune mediators made on 2112 samples from 871 participants. Meta-analyses were performed on 53 immune mediators. Antibodies, CC-type chemokines, MMPs, IL-6, IL-16, IL-1RA, G-CSF, GNLY, and ICAM1 were lower in the luteal phase than the follicular phase. Only IL-1α, HBD-2, and HBD-3 were elevated in the luteal phase. There was minimal change between the phases for CXCL8, 9, and 10, interferons, TNF, SLPI, elafin, lysozyme, lactoferrin, and interleukins 1β, 2, 10, 12, 13, and 17A. The GRADE strength of evidence was moderate to high for all immune mediators listed here.

CONCLUSIONS: Despite the variability of cervicovaginal immune mediator measurements, our meta-analyses show clear and consistent changes during the menstrual cycle. Many immune mediators were lower in the luteal phase, including chemokines, antibodies, matrix metalloproteinases, and several interleukins. Only interleukin-1α and beta-defensins were higher in the luteal phase. These cyclical differences may have consequences for immunity, susceptibility to infection, and fertility. Our study emphasizes the need to control for the effect of the menstrual cycle on immune mediators in future studies.

ABSTRACT

OBJECTIVE: Oesophageal foreign bodies (EFBs) are a common emergency issue in paediatrics, and few studies have revealed its clinical features and treatment methods. We conducted this retrospective study to provide our 10-year clinical evidence for the diagnosis and treatment of EFB and reduce the incidence of complications.

METHODS: We retrospectively reviewed all paediatric cases diagnosed with EFB from January 2012 to December 2021 at Shenzhen Children’s Hospital. The age and sex of the patients, types of foreign bodies (FBs), preoperative examination, location and duration of FB impaction, clinical symptoms, surgical methods, therapeutic effects and complications were analysed.

RESULTS: Among the 1355 cases, 759 were boys and 596 were girls, with a median age of 2.9 years (4 months to 16 years). The shortest FB lodged time was 1 hour, while the longest time was 3 months. The types of foreign bodies included coins and blunt objects (812,59.9%), bones and sharp objects (278,20.5%), button batteries (86,6.3%), food impactions (84,6.2%), toys (51,3.8%) and plastic objects (44,3.2%). A total of 720 of 812 cases impacted by coins and blunt subjects were successfully treated with a Foley catheter without any complications. A total of 558 patients underwent rigid oesophageal endoscopy under general anaesthesia, and foreign bodies were successfully removed in 525 cases. No FB was found in 33 cases, and FBs pushed into the lower digestive tract during operation in 5 cases. Oesophageal injury was found in 130 cases (23.3%). Our study showed that the age of the patient, time of foreign body incarceration, type of foreign body, location of the lodged foreign body, and fever or cough were risk factors leading to oesophageal foreign body complications, and the differences were statistically significant (P < 0.05).

CONCLUSION: Children with EFB have a risk of complications, especially if the FB is a button battery. The appropriate surgical method should be selected through the analysis of the clinical characteristics of the foreign body in the oesophagus and the risk factors for complications to reduce the incidence of complications. Health education and effective care are the keys to the prevention of EFB.

ABSTRACT

BACKGROUND: Global evidence indicates increases in gender-based violence (GBV) during the COVID-19 pandemic following mitigation measures, such as stay at home orders. Indirect effects of the pandemic, including income loss, strained social support, and closed or inaccessible violence response services, may further exacerbate GBV and undermine help-seeking. In Kenya and Burkina Faso, as in many settings, GBV was prevalent prior to the COVID-19 pandemic. Studies specific to COVID-impact on GBV in Kenya indicate mixed results and there remains a lack of evidence from Burkina Faso. Our study takes a comprehensive lens by addressing both intimate partner violence (IPV) and non-partner household abuse through the COVID-19 pandemic in two priority settings.

METHODS: Annual, national cross-sections of women ages 15-49 completed survey data collection in November-December 2020 and December 2020-March 2021; the GBV module was limited to one woman per household [Kenya n = 6715; Burkina n = 4065]. Descriptive statistics, Venn diagrams, and logistic and multinomial regression characterized prevalence of IPV and other household abuse, frequency relative to the COVID-19 pandemic, help-seeking behaviors, and predictors of IPV and household abuse across the socioecological framework.

RESULTS: In both settings, past-year IPV prevalence exceeded non-partner household abuse (Kenya: 23.5%_IPV, 11.0%_household; Burkina Faso: 25.7%_IPV, 16.2%_household). Over half of those affected in each setting did not seek help; those that did turned first to family. Among those with past-year experiences, increased frequency since COVID-19 was noted for IPV (16.0%_{Burkina Faso}; 33.6%_Kenya) and household violence (14.3%_{Burkina Faso}; 26.2%_Kenya). Both context-specific (i.e., financial autonomy in Burkina Faso) and universal (i.e., COVID-related income loss) risk factors emerged.

CONCLUSION: Past-year IPV and household violence against women in Kenya and Burkina Faso were prevalent, and in some cases, intensified during the COVID-19 pandemic. Across settings, help-seeking from formal services was notably low, likely reflecting shame, blame, and stigmatization identified as barriers in pre-COVID literature. Both primary prevention and survivor-centered support services, including those related to economic empowerment, should be integrated within COVID-recovery efforts, and extended into the post-pandemic period to fully meet women’s safety needs.

ABSTRACT

BACKGROUND: Pain is the most common symptom reported by caregivers of children with severe neurological impairment (SNI), a descriptive term for children with disorders affecting the neurological system across multiple domains. In SNI, cognition, communication, and motor skills are impaired and other organ systems are impacted. Pain is difficult to identify and treat in children with SNI because of communication impairment. When a clear cause of pain is not determined, the term “Pain and Irritability of Unknown Origin (PIUO)” is used to describe pain-like behaviours. This study explores the clinical care received by children with SNI admitted to hospital after presenting to the emergency department of a tertiary pediatric hospital with pain or irritability. Findings are compared to the approach suggested in the PIUO pathway, an integrated clinical pathway for identifying and treating underlying causes of pain and irritability in children with complex conditions and limited communication.

METHODS: Retrospective chart review of children (age 0 to 18 years inclusive) with diagnoses compatible with SNI presenting with pain, irritability, and/or unexplained crying that required hospitalization between January 1st, 2019 and December 31st, 2019. Descriptive statistics were used to analyze the clinical care received by children in whom a source of pain was identified or not. In children for whom no cause of pain was identified, investigations completed were compared to the PIUO pathway.

RESULTS: Eight hospital admissions of six unique children were included for data analysis. A cause for pain and irritability was identified and resolved in three patients. In children with PIUO, there were gaps in history taking, physical examination, and investigations that might have allowed a cause of pain and irritability to be found. Pain was assessed using the r-FLACC pain scale and varying medications for pain/irritability were given during each hospital admission.

CONCLUSION: Children with SNI admitted to a tertiary pediatric hospital did not undergo a standardized approach to identifying a cause of pain and irritability. Future efforts should explore the effectiveness of the PIUO pathway, a standardized approach to reducing and resolving pain in children with SNI.

ABSTRACT

Although the genetic correlations between complex traits have been estimated for more than a century, only recently we have started to map and understand the precise localization of the genomic region(s) that underpin these correlations. Reproductive traits are often genetically correlated. Yet, we don’t fully understand the complexities, synergism, or trade-offs between male and female fertility. In this study, we used reproductive traits in two cattle populations (Brahman; BB, Tropical Composite; TC) to develop a novel framework termed correlation scan (CS). This framework was used to identify local regions associated with the genetic correlations between male and female fertility traits. Animals were genotyped with bovine high-density single nucleotide polymorphisms (SNPs) chip assay. The data used consisted of ~1000 individual records measured through frequent ovarian scanning for age at first corpus luteum (AGECL) and a laboratory assay for serum levels of insulin growth hormone (IGF1 measured in bulls, IGF1b, or cows, IGF1c). The methodology developed herein used correlations of 500-SNP effects in a 100-SNPs sliding window in each chromosome to identify local genomic regions that either drive or antagonize the genetic correlations between traits. We used Fisher’s Z-statistics through a permutation method to confirm which regions of the genome harboured significant correlations. About 30% of the total genomic regions were identified as driving and antagonizing genetic correlations between male and female fertility traits in the two populations. These regions confirmed the polygenic nature of the traits being studied and pointed to genes of interest. For BB, the most important chromosome in terms of local regions is often located on bovine chromosome (BTA) 14. However, the important regions are spread across few different BTA’s in TC. Quantitative trait loci (QTLs) and functional enrichment analysis revealed many significant windows co-localized with known QTLs related to milk production and fertility traits, especially puberty. In general, the enriched reproductive QTLs driving the genetic correlations between male and female fertility are the same for both cattle populations, while the antagonizing regions were population specific. Moreover, most of the antagonizing regions were mapped to chromosome X. These results suggest regions of chromosome X for further investigation into the trade-offs between male and female fertility. We compared the CS with two other recently proposed methods that map local genomic correlations. Some genomic regions were significant across methods. Yet, many significant regions identified with the CS were overlooked by other methods.

ABSTRACT

BACKGROUND: Overexpression of the EVI1 (ecotropic viral integration site 1) oncogene has recently been implicated as a prognostic factor in breast cancer (BC), particularly in triple-negative BC (TNBC). In this study we aimed to investigate frequency and clinical relevance of EVI1 expression in newly diagnosed BC treated with neoadjuvant chemotherapy.

METHODS: EVI1 expression was determined by immunohistochemistry using H-score as a cumulative measurement of protein expression in pretherapeutic biopsies of BC patients treated with anthracycline/taxane based neoadjuvant chemotherapy within the GeparTrio trial. EVI1 was analyzed as a continuous variable and dichotomized into low or high based on median expression. Endpoints were pathological complete response (pCR), disease-free survival (DFS) and overall survival (OS).

RESULTS: Of the 993 tumors analyzed, 882 had available subtype information: 50.8% were HR + /HER2-, 15% HR + /HER2 + , 9.8% HR-/HER2 + , and 24.5% TNBC. Median EVI1 H-score was 112.16 (range 0.5-291.4). High EVI1 expression was significantly associated with smaller tumor size (p = 0.002) but not with BC subtype. Elevated EVI1 levels were not significantly associated with therapy response and survival in the entire cohort or within BC subtypes. However, TNBC patients with high EVI1 showed a trend towards increased pCR rates compared to low group (37.7% vs 27.5%, p = 0.114; odds ratio 1.60 (95%CI 0.90-2.85, p = 0.110) and numerically better DFS (HR = 0.77 [95%CI 0.48-1.23], log-rank p = 0.271) and OS (HR = 0.76 [95% 0.44-1.31], log-rank p = 0.314) without reaching statistical significance.

CONCLUSION: EVI1 was not associated with response to neoadjuvant therapy or patient survival in the overall cohort. Further analyses are needed to verify our findings especially in the pathological work-up of early-stage HER2-negative BC patients.
