Using an anatomic model to teach female stress incontinence to gynecologic residents‑in‑training: A prospective cohort study / Philippine Journal of Obstetrics and Gynecology

Background@#Stress urinary incontinence (SUI) is a complex condition with a multifactorial etiology that makes its concepts challenging to teach. This study aimed to assess the efficacy of simulation-based training (SBT) with an anatomic teaching model in improving the understanding of SUI among gynecologic residents-in-training. @*Objective@#The primary objective of this study was to evaluate the efficacy of SUI simulation-based teaching in enhancing the learning experience for gynecologic residents-in-training. The secondary objective was to gather feedback from participants with the intent to further enhance existing teaching methodologies.@*Materials and Methods@#This was a descriptive prospective study within a single institution, involving gynecologic residents-in-training. Participants were given an anatomic teaching tool to construct, followed by an SUI lecture. Pre- and posttest Multiple Choice Questions were administered to assess the efficacy of the teaching tool in improving the participants’ understanding of SUI. Frequency and percentages were used to describe the categorical variables, whereas continuous variables were described using mean and standard deviation. Paired t-test was used to compare the pre- and posttest scores. ANOVA was used to compare the pre- and posttest scores of participants by year level. A P < 0.05 is statistically significant. A separate Likert-scale questionnaire, to evaluate changes in participant’s self-assessment on learning, response to teaching content and resources, and overall feedback of the SBT was used.@*Results@#There were 50 gynecologic residents-in-training that were included in the study. The mean posttest score is significantly higher (6.4 vs. 3.48) than the pretest score, with a mean difference of 3.48. The mean posttest score is significantly different between the year levels with a P < 0.05, with senior residents-in-training performing best. Although participants with only gynecologic conferences as SUI reference performed best, the mean pre- and posttest scores were not statistically different with respect to SUI education exposure. With the use of an anatomic SUI model, the number of correct answers for questions pertaining to anatomy, physiology, and pathophysiology was consistently higher in the posttest scores as compared to the pretest scores but did not reach statistical significance. The majority of participants strongly agree to recommend the course to a colleague.@*Conclusion@#This study supports the use of simple, low-fidelity physical teaching tools in improving the understanding of SUI in gynecologic residents-in-training. Considering the ease of production, improved test scores, and participants’ enthusiasm, the incorporation of the anatomic teaching tool for its use in SUI education should be encouraged.

Detección de eventos adversos en pacientes internados en clínica médica utilizando la herramienta Global Trigger Tool / Detection of adverse events in patients interned in medical clinic using the Global Trigger Tool

Resumen Introducción : El Global Trigger Tool (GTT) es una herramienta que identifica con precisión los eventos adversos, estos representan un problema relevante y prevenible en los hospitales. Métodos : Estudio de corte transversal basado en la revisión retrospectiva de historias clínicas aleatorizadas utilizando el GTT. Resultados : Se detectaron 161 eventos adversos (EA): 51 por cada 100 admisiones, 66 por cada 1000 días pa ciente y 30% de admisiones con EA. Los disparadores más frecuentes fueron del módulo cuidados, 25% com plicaciones asociadas al uso de procedimientos, 10% úlceras por presión y 9% infecciones asociadas a la atención. La presencia de EA tuvo asociación estadís ticamente significativa con estancia mayor a 5 días, y asociación moderada con edad y número de disparado res. En cuanto al daño, 78% de los pacientes presentaron eventos leves y 4% eventos fatales. En el análisis con cur vas ROC, los disparadores con mayor área bajo la curva fueron: complicación de procedimientos (0.70), úlceras por presión (0.61) y código de respuesta rápida (0.60). Discusión : Los eventos por 100 admisiones fueron superiores a la bibliografía pero no hubo diferencias en eventos por cada 1000 días paciente. Los casos fatales se produjeron por enfermedades infecciosas respiratorias en pacientes con comorbilidades, necesidad de sonda nasogástrica y deterioro cognitivo. Se destaca la escasa aplicación de la herramienta en hospitales públicos, y la implementación de análisis de disparadores con cur vas ROC. Conocer la frecuencia y el tipo de evento más frecuente permitirá implementar medidas que mejoren la seguridad de los pacientes.

Abstract Introduction : The Global Trigger Tool (GTT) is a tool that accurately identifies adverse events that represent a significant problem in hospitals. Methods : Cross-sectional study based on retrospec tive review of randomized medical records using the GTT tool. Results : A total of 161 adverse events (AEs) were detected: 51 events per 100 admissions, 66 per 1000 patient-days, and 30% of admissions with AEs. The most frequent triggers were from the care module, with 25% complications associated with the use of procedures, 10% pressure ulcers, and 9% care-associated infections. The presence of AEs had a statistically significant asso ciation with a stay of more than 5 days, and a moderate association with age and number of triggers. Regarding the damage, 78% of the patients presented mild events and 4% fatal events. The ROC curves analysis showed that the triggers with the greatest area under the curve were: procedural complication (0.70), pressure ulcers (0.61) and rapid response code (0.60). Discussion : The number of events per 100 admis sions was higher than that reported in the literature, but there were no differences in events per 1000 patient-days. Fatal cases were caused by respiratory infectious diseases in patients with comorbidities, nasogastric tube needs and cognitive decline. The study highlights the scarce use of the tool in public hospitals and the implementation of trigger analysis with ROC curves. Knowing the frequency and the most frequent type of event will allow the implementation of measures that improve patient safety.

Comparative analysis of primary health care attributes between children under and over 3 years of age using the primary care assessment tool

Abstract Introduction: Child health actions in Brazil have their primary focus on early childhood. A new epidemiological profile is emerging for children after the first one thousand days: an increase in non-communicable chronic diseases. This research aimed to analyze the attributes of Primary Health Care comparatively among different age groups, using three years of age as the cutoff point. Methods: The study design was cross-sectional and conducted in three Primary Health Care Units and three Ambulatory Medical Assistance facilities in the Western Region of Sao Paulo. The PCA Tool Brazil was used as the assessment instrument. Results: A total of 311 interviews were conducted with caregivers of children aged 0 to 12 years; 153 children were under three years old, and 158 were three years or older. The attributes that showed statistically significant differences between age groups (< 3 years and > 3 years) were affiliation (4.9 × 3.8), longitudinality (5.7 × 5.2), information system (7.4 × 6.3), and services provided (5.4 × 4.5). Through linear regression analysis, it was observed that there was a trend for better overall and essential scores in the evaluations of the group of children under three years old who attended Primary Health Care Units. Conclusion: The comparative analysis of Primary Health Care attributes among pediatric age groups revealed a trend towards higher scores, according to caregivers' perceptions, for children under three years old. This study suggests the need for the implementation of programs that can better address the healthcare needs of children beyond early childhood.

Applicability of near-miss tools to address maternal mortality

In India, there is a mandate to increase institutional delivery, which has led to an overwhelming response in health-care delivery. The maternal mortality rate has been an essential yardstick, used by health-care planners to assess the quality of obstetric services. As of late, there has been a shift in focus to maternal near-misses (MNMs) as a more valuable indicator of maternal health than the maternal mortality rate. The aim of this research article was to compare various standardized tools to address MNM, namely, the World Health Organization MNM tool, The Government of India's facility-based MNM review tool, etc.

A Bacteriological of Make-up Tools Used in Calabar Metropolis, Cross River State, Nigeria

Sharing of make-up tools by multiple users is a possible means of transfer of fungal infections, such as dermatophytoses. With abrasion on the skin, it is possible for HIV, Hepatitis B virus, Spirochaetes and other pathogens to be carried via contaminated make-up tools, from one person to another. Using sterilized swab sticks, surfaces of make-up tools (sponge and brush) were cleansed. Materials deposited on the swab sticks were cultured aerobically on Chocolate and Cysteine Lactose Electrolyte Deficient Agar plates overnight at 37oC. After overnight aerobic incubation, the culture plates were read macroscopically for growth. Bacterial isolates were subjected to microscopic examination using Gram’s staining technique and biochemical tests (e.g. coagulase, catalase, oxidase, and motility). Results showed that the predominant bacterial growths obtained from the make-up tools were Staphylococcus aureus (51.5%), Coagulase-negative Staphylococcus (25.8%), Klebsiella pneumoniae (6.2%), and Pseudomonas aeruginosa (16.5%). The different genera of bacteria were harvested from make-up brushes (66.2%) and make-up sponges (85.7%). There was no bacterial growth from 33.8% and 14.3% of make-up brushes and make-up sponges respectively. There was no statistical difference in terms of bacterial growth between the two tools (brush and sponge) sampled (P>0.05). This study has shown that there is a moderate possibility for the transfer of bacterial organisms (both skin flora and pathogens) from one person to another, through make-up tools, in our local communities. It is hereby recommended that health education talks should be carried out regularly among beauticians to encourage them to use disposable make-up tools with disinfectants.

A Strategy for Inpatient Evaluation and Improvement of the Quality of Our Palliative Care Team: Iterative Evaluations of Changes in a Palliative Screening Tool

To introduce early palliative care to patients, we have proactively used a palliative care screening tool to identify needs. We have emphasized not doing work in a routine manner, rather seeking to improve by continuous reevaluations. Because of a lack of feedback regarding changes in screening scores and actionable solutions derived from it, we executed a retrospective study about the effectiveness of our palliative care team and the identification of problems. All 91 cases studied meaningfully ameliorated their focused symptoms. However, we could not verify our team’s effectiveness because the backgrounds of patients who were eligible but not involved with our team differed significantly. The current study suggested that some patients missed opportunities to receive palliative care. We need to strengthen the system used with our patients as a safety-net so as not to overlook care opportunities by utilizing more effective screening methodology.

Advances in the study of examination methods for dry eye / 国际眼科杂志(Guoji Yanke Zazhi)

Dry eye is a multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film, and accompanied by ocular symptoms. In recent years, the incidence of dry eye has been increasing year by year, and the diagnosis and treatment of dry eye are constantly evolving and innovating. However, due to the corresponding drawbacks of traditional examination methods and the lack of a large number of clinical trial studies on new examination methods, there is still no unified standard for the diagnosis and treatment of dry eye. In this review, we have performed a broad search for articles discussing different examination methods for dry eye, including promising diagnostic tools and technique, the latest advances, and contradictions, in order to provide a review of dry eye examination methods including the tear volume, the tear film, the eyelid and meibomian gland, and the degree of damage to the epithelial cells of the ocular surface, and provide a reference for the diagnosis and treatment of dry eye.

OBJECTIVE@#To re-evaluate the systematic review/Meta-analysis of acupuncture and moxibustion for childhood autism (CA), aiming to provide decision-making basis for clinical diagnosis and treatment.@*METHODS@#The systematic review and/or Meta-analysis of acupuncture and moxibustion for CA were searched in PubMed, EMbase, Cochrane Library, SinoMed, CNKI and Wanfang databases. The retrieval time was from the database establishment to May 5th, 2022. PRISMA (preferred reporting items for systematic reviews and Meta-analyses) was used to evaluate the report quality, and AMSTAR 2 (a measurement tool to assess systematic reviews 2) was used to evaluate the methodological quality, bubble map was used to construct the evidence map and GRADE was used to evaluate the quality of evidence.@*RESULTS@#A total of 9 systematic reviews were included. The PRISMA scores ranged from 13 to 26. The report quality was low, and there was a serious lack in the aspects of program and registration, search, other analysis and funding. The main problems in methodology included not making prespecified protocol, incomplete retrieval strategy, not providing a list of excluded literatures, and incomplete explanation on heterogeneity analysis and bias risk. The evidence map showed that 6 conclusions were valid, 2 conclusions were possible valid and 1 conclusion was uncertain valid. The overall quality of evidence was low, and the main factors leading to the downgrade were limitations, followed by inconsistency, imprecision and publication bias.@*CONCLUSION@#Acupuncture and moxibustion has a certain effect for CA, but the quality of reporting, methodology and evidence in included literature need to be improved. It is suggested to perform high-quality and standardized research in the future to provide evidence-based basis.

Usefulness of the STarT Back Screening Tool to Predict the Effect of Acupuncture Treatment: Evaluation of Its Risk Classification Focusing on the Changes in the Lumbar Pain Visual Analog Scale / 日本温泉気候物理医学会雑誌

  Background: The STarT (Subgrouping for Targeted Treatment) Back Screening Tool (SBST) is an established clinical evaluation tool that easily assesses the risk of chronic or refractory low back pain. This study aimed to examine the usefulness of acupuncture in patients with low back pain.  Methods: A total of 71 outpatients with low back pain who underwent acupuncture and moxibustion at the Center for Integrative Medicine, Tsukuba University of Technology, between 2019 and 2022 were included in this study, regardless of the specific medical condition causing the pain. Survey items included the SBST and lumbar pain intensity visual analog scale (VAS). Demographic factors and contents of acupuncture treatment were collected from the medical charts. The VAS score 4 weeks after the start of treatment was used as an index of clinical outcome and was analyzed using repeated measures analysis of variance (ANOVA) and hierarchical multiple regression analysis.  Results: Classification using the SBST at the first visit resulted in 36, 30, and 15 patients in the low-, medium-, and high-risk groups, respectively. Repeated-measures ANOVA showed statistically significant differences in the mean VAS values with respect to differences in time point (P < 0.01), group (P < 0.01), and interaction (P < 0.05). The VAS values after 4 weeks in the high-risk group were significantly higher than those in the other two groups (both P < 0.01). In the hierarchical multiple regression analysis, with VAS as the dependent variable, the relationship between SBST classification and VAS maintained a significant positive relationship in all models, including adjustments for interaction terms and patients’ background items. A simple slope analysis indicated that this relationship was more evident in patients with lower limb symptoms than in those without symptoms.  Conclusion: The SBST could be a simple and useful tool for predicting the clinical outcomes of acupuncture.

OBJECTIVE@#To determine the reliability and validity of the modified pediatric nutrition screening tool in identifying malnutrition and risk of malnutrition among admitted pediatric patients aged 6 to 18 years old.@*METHOD@#The Modified Pediatric Nutritional Screening Tool (PNST) was used to assess 130 admitted patients aged 6 to 18 years old. Evaluation of anthropometric measurements, body weight changes, clinical conditions and dietary intake were done within 48 hours of admission. Intraclass correlation coefficient was used to determine reliability of the tool among different raters while chi square test was used to determine correlation of the tool with the Screening Tool for the Assessment for Malnutrition in Pediatrics (STAMP).@*RESULT@#The comparison of the modified PNST measurements by two observers showed no significant difference with p value of 0.078. All PNST criteria except clinical condition were associated with risk of malnutrition based on STAMP. The overall modified PNST criteria is significantly associated with risk of malnutrition based on STAMP.@*CONCLUSION@#The modified PNST accurately identifies malnutrition and risk of malnutrition among admitted patients aged 6-18 years old. The criteria used in the modified PNST were strongly associated with risk for malnutrition measured using previously validated tools and demonstrates a good interobserver reliability. It is recommended to be used as routine screening in the hospital set- ting for early identification of malnutrition and risk for malnutrition.

Research progress of nutrition literacy assessment for children and adolescents / 中国学校卫生

Abstract@#Children and adolescents are at an important stage in the development of eating habits and food skills. Nutrition literacy is inseparable from healthy eating behaviors and higher nutritional quality, and improving nutrition literacy is an important pathway to better nutrition. The paper summarizes domestic and international research on nutrition literacy from the perspectives of definition and assessment tools in children and adolescents. It is found that there is no universal definition of nutritional literacy. Adult nutrition literacy or with appropriate adjustments are widely used in children and adolescents, without taking into account the unique developmental characteristics and nutritional needs of children and adolescents; the measurement tools of nutritional literacy are diverse, and there is no unified assessment tools, so it is difficult to compare and analyze research findings and draw reliable conclusions. In the future, authoritative definitions, and standardized evaluation tools are in great need.
