ABSTRACT

OBJECTIVE: This study aimed to introduce, sensitize, and train our postgraduate students and faculty of the department of general surgery with the use of mini-Clinical Evaluation Exercise (mini­CEX) and to assess the perception of students and faculty towards it. MATERIAL AND METHODS: A cross­sectional observational study was conducted over a period of four months. Ten surgery residents in the department were asked to volunteer to participate and five professors conducted the session. Five sessions of mini­CEX (nine points) were conducted for each resident in different settings of the out­patient department (OPD) and in­patient department (IPD). A total of five skills were tested. Feedback from faculty and residents regarding the perception of mini­CEX was also taken. RESULTS: A statistically significant difference in mean scores of all domains was observed comparing the first and last assessment (p<0.05). Hundred percent of the residents scored superior category (7-9) in the final assessment in all domains, whereas the maximum was in a satisfactory scoring grade in 1st assessment. The time taken for the assessment significantly reduced from 1st assessment to the last assessment in OPD and IPD settings (p=0.001). The mini-CEX assessment tool got 100% feedback from faculty in terms of skill improvement, method, attitude of residents, and ability to identify gaps in knowledge. However, one assessor thought that "time given for assessment" was inadequate and more effort was required than the usual traditional assessment methods. The most identified problem faced by residents was that the "time given during assessment" was less (50%); however, overall residents also found it valid, effective, and helpful in identifying knowledge gaps and improving clinical and communication skills. CONCLUSION: Mini­CEX improves the learning environment in residency and also leads to improvement in medical interviewing skills, physical examination skills, humanistic qualities/professionalism, and counseling skills. So, it can be used for residency training in clinical departments.

ABSTRACT

Applying safety means in the industry, especially in the petroleum industry is very important to maintain the industrial facility. A semi-quantitative risk assessment as Layers of Protection Analysis (LOPA) is used widely to quantify data after qualitative risk analysis as HAZOP using a simpler way than quantitative risk analysis 'QRA' as fault tree analysis 'FTA'. This determines if a new safety integrity function 'SIF' is needed. This paper introduces a novel fuzzy logic system to solve the failure of crude oil shipping pumps. Several models are studied to select the most appropriate fuzzy membership functions. Results are compared with results from the LOPA model, which shows the advantages of using the proposed model to reduce the RRF for the potential hazard and achieve a simple and reliable control method.

ABSTRACT

INTRODUCTION: Tooth extraction in children requires attention to wound healing and pain management, which are influenced by patient-related factors and behavioral guidance. AIM OF THE STUDY: The study aimed to evaluate the effect of LLLT on healing sockets in pediatric patients with bilateral primary molar teeth extraction and determine its impact on pain management. METHODS: 6-10 years of age, systemically healthy, and with atraumatic extraction indications of bilateral primary molar teeth were included in the study (n = 40). In the first session, randomly selected teeth were extracted under local anesthesia. In the control group, only clot formation in the socket was observed and photographed. The other group extractions were performed 2 weeks later. The low-level laser therapy (LLLT) group was treated with a 980 nm wavelength, in a continuous emission mode, 0.5 W power, 300 J of energy, 400 µm tip, 60 s diode laser and photographed. Nonepithelialized surface measurements were performed using ImageJ. Pain assessment was performed using the Wong-Baker Pain Scale. Statistical analyses were performed using SPSS software. RESULTS: There was a statistically significant difference between the groups in the Wong-Baker values in 3rd day (p < 0.05). In soft tissue healing on the 3rd and 7th day, the nonepithelialized surface of the laser socket was smaller than that of the control group, and the measurement results were found to be statistically significant (p < 0.05). CONCLUSION: Although LLLT was not found to be very effective in reducing postoperative discomfort after extraction of primary molars, it provided better wound healing in extraction sockets.

ABSTRACT

Development of New Approach Methodologies (NAMs) capable of providing a No Expected Sensitization Induction Level (NESIL) value remains a high priority for the fragrance industry for conducting a Quantitative Risk Assesment (QRA) to evaluate dermal sensitization. The in vitro GARDskin assay was recently adopted by the OECD (TG 442E) for the hazard identification of skin sensitizers. Continuous potency predictions are derived using a modified protocol that incorporates dose-response measurements. Linear regression models have been developed to predict human NESIL values. The aim of the study was to evaluate the precision and reproducibility of the continuous potency predictions from the GARDskin Dose-Response (DR) assay and its application in conducting QRA for fragrance materials using a Next Generation Risk Assessment (NGRA) framework. Results indicated that the GARDskin Dose-Response model predicted human NESIL values with a good degree of concordance with published NESIL values, which were also reproducible in 3 separate experiments. Using Isocyclocitral as an example, a QRA was conducted to determine its safe use levels in different consumer product types using a NGRA framework. This study represents a major step towards the establishment of the assay to derive NESIL values for conducting QRA evaluations for fragrance materials using a NGRA framework.

ABSTRACT

A consensus guideline, iRECIST, was developed by the Response Evaluation Criteria in Solid Tumours (RECIST) working group for the use of the modified RECIST version 1.1 in cancer immunotherapy trials. iRECIST was designed to separate pseudoprogression from real progression. However, this is not the only ambiguous situation. In clinical immunotherapy trials, stable disease may reflect three tumor responses, including real stable disease, progressive disease and responsive disease. The prediction of a "true complete/partial response" is also important. Much data has accumulated showing that ctDNA can guide decisions at this point; thus, integrating ctDNA into the RECIST 1.1 criteria may help to distinguish a true tumor response type earlier in patients treated with immunotherapy; however, prospectively designed validation studies are needed.

ABSTRACT

OBJECTIVES: To conduct a methodological overview of reviews to evaluate the reporting completeness and transparency of systematic reviews (SRs) of prognostic prediction models (PPMs) for COVID-19. STUDY DESIGN AND SETTING: MEDLINE, Scopus, Cochrane Database of Systematic Reviews, and Epistemonikos (epistemonikos.org) were searched for SRs of PPMs for COVID-19 until December 31, 2022. The risk of bias in systematic reviews tool was used to assess the risk of bias. The protocol for this overview was uploaded in the Open Science Framework (https://osf.io/7y94c). RESULTS: Ten SRs were retrieved; none of them synthesized the results in a meta-analysis. For most of the studies, there was absence of a predefined protocol and missing information on study selection, data collection process, and reporting of primary studies and models included, while only one SR had its data publicly available. In addition, for the majority of the SRs, the overall risk of bias was judged as being high. The overall corrected covered area was 6.3% showing a small amount of overlapping among the SRs. CONCLUSION: The reporting completeness and transparency of SRs of PPMs for COVID-19 was poor. Guidance is urgently required, with increased awareness and education of minimum reporting standards and quality criteria. Specific focus is needed in predefined protocol, information on study selection and data collection process, and in the reporting of findings to improve the quality of SRs of PPMs for COVID-19.

Introduction: CAPE-V is widely used for vocal perceptual evaluation and has been adapted and validated in multiple languages. Through an exhaustive analysis, this study sought to advance in establishing a standard in the method used in its adaptation and validation. Objective: To review articles published between 2002 and 2022 that have adapted and validated CAPE-V in different languages, to thoroughly evaluate the adaptation, methodology, and statistics used. Methods: A systematic review was conducted using Scopus, Google Scholar and PubMed to identify articles that adapted and/or validated CAPE-V between 2002 and 2022. The title and summary were analyzed to pre-select the sample. To evaluate the risk of bias of the included studies, the full text was critically analyzed. Results: The initial search identified 568 items. When duplicates were removed, 559 were reviewed and 23 were pre-selected. 12 were finally included and analyzed considering adaptation, methodology, and statistical analysis. The results show that the adaptation and validation of CAPE-V to different languages is essential to ensure accurate and reliable measurements in different populations. Analysis and discussion: There is heterogeneity in how CAPE-V is adapted and validated. However, all studies were successful in producing valid results, underlining the importance of these processes for clinical practice. Conclusions: Adaptations and validations of CAPE-V were performed heterogeneously due to the absence of a standard protocol. It is necessary to generate guidelines to perform these processes by providing this scale to the clinic, ensuring quality and reliability of results.

ABSTRACT

Resumen Este estudio analizó la relación entre la evaluación del producto y la evaluación del proceso de los patrones básicos de movimiento saltar y lanzar. 40 sujetos, todos hombres, 10.03 ± 0.3 años, 37.82 ± 13.9 kg, 139 ± 28 cm y 19.38 ± 4.5 IMC (kg/m2). Se utilizó el Instrumento Patrones Básicos de Movimiento (IPBM) para la evaluación del proceso; en los productos se realizaron las pruebas salto de longitud y de lanzamiento por encima del hombro para saltar y lanzar, respectivamente. Se hizo estadística descriptiva (promedios y desviaciones estándar) para las medidas antropométricas y para analizar la relación de los resultados de los dos intentos de producto y de proceso, correlación de Spearman a un nivel de significancia de p ≤ .05 y p ≤ .01. Las correlaciones obtenidas expusieron la existencia de una relación positiva y significativa entre la evaluación del proceso y la evaluación del producto de saltar en el intento 1 (r = 0.447; p = .004; r2 = 0.200) y en el intento 2 (r = 0.562; p < .0001; r2 = 0.316), de igual forma entre la evaluación del proceso y la evaluación del producto de lanzar en el intento 1 (r = 0.332; p = .043; r2 = 0.011) y en el intento 2 (r = 0.311; p = .051, r2 = 0.097). La correlación indica que los sujetos con mejores resultados en las evaluaciones orientadas al proceso tienen mejores resultados en las evaluaciones orientadas al producto; sugiere que, al mejorar la técnica, se puede mejorar el producto. Al comprender cómo la evaluación orientada al proceso y la evaluación orientada al producto se relacionan entre sí e identificar qué se quiere medir y para qué, se puede esperar objetividad en los métodos de la valoración de la ejecución del movimiento humano desde el enfoque del proceso y el producto.


Abstract This study examines the relationship between output assessment and process assessment for basic movement patterns in jumping and throwing. Forty subjects, all male, 10.03 ± 0.3 years old, 37.82 ± 13.9 kg, 139 ± 28 cm and 19.38 ± 4.5 IMC (kg/m2) participated. The Basic Movement Patterns Instrument (IPBM) was used for assessing the process. For the output, length jump and over-the-shoulder throw tests were made for jumping and throwing, respectively. A descriptive statistics was carried out (averages and standard deviations) for the anthropometric measurements, and for examining the relationship of the outcomes of the two output and process attempts, Spearman correlation at a significance level of p ≤ 0.5 and p ≤ .01 was used. The resulting correlations showed the existence of a positive and significant relationship between process assessment and output assessment of jumping of (r = 0.447; p = .004; r2 = 0.200) in attempt 1 and of (r = 0.562; p < .0001; r2 = 0.316) in attempt 2. Similar results were found between process assessment and output assessment of throwing, (r = 0.332; p = .043; r2 = 0.011) in attempt 1 and (r = 0.311; p = .051, r2 = 0.097) in attempt 2. The correlation indicates that the subjects with the best results in process-oriented assessments have better results in output-oriented assessments; this suggests that the output can be improved by improving the technique. In understanding how process-oriented assessment and output-oriented assessment are mutually related, and in identifying what you want to measure and for what purpose, objectivity can be expected in the methods for assessing the performance of human movement with a process and output approach.

ABSTRACT

OBJECTIVE: This study examines the Turkish validity, reliability and diagnostic performance of the Voice Handicap Index-Partner (VHI-P-TR), which is used to obtain the perceptions of communication partners of individuals with dysphonia about the functional, physical and emotional handicap resulting from the patient experiencing dysphonia. METHOD: The study included 160 individuals with dysphonia and their communication partners. First, translation, back translation, expert validity and pilot study were performed in the scale adaptation process. Then, a confirmatory factor analysis (CFA) was conducted to assess the construct validity of the VHI-P-TR. Correlations between the VHI-P-TR and Voice Handicap Index (VHI-TR) scores of dysphonic individuals were examined to evaluate the concurrent validity of the VHI-P-TR. To assess the reliability of the VHI-P-TR, a test-retest analysis was performed, and internal consistency coefficients (α) were calculated. A receiver operating characteristic (ROC) analysis was conducted to determine the cut-off point for the VHI-P scores. RESULTS: A high positive correlation was found between the participants' VHI-P-TR and VHI-TR total and subscales mean scores (r's > 0.782; p < 0.01). The VHI-P-TR had high internal consistency regarding for its subscales and total score (α's > 0.94; p < 0.01). Factor loadings of all VHI-P-TR items were higher than 0.30 and their error variances were lower than 0.90. In addition, factor loadings were statistically significant for all the items (p < 0.05). The data fit the model well according to all CFA indices except for GFI (scale = 0.69). An adequate sensitivity and specificity were achieved for the VHI-P-TR, and the cut-off point was found as 11.50 for the total score and ranged from 2.50 to 5.50 for the subscales. CONCLUSION: The VHI-P-TR is a valid and reliable measurement tool with high diagnostic performance in all subscales and total score, and has high levels of agreement with the VHI-TR.

ABSTRACT

Providing adequate Water Sanitation and Hygiene (WASH) in Health Care Facilities (HCFs) has many benefits, including achieving Sustainable Development Goals (SDGs) and Universal Health Coverage (UHC). However, there is a significant shortage of statistics on the status of WASH in Healthcare Facilities (WinHCF), resulting in roadblocks in developing improvement strategies. Further, there is a lack of detailed comparison of WASH components covered in available tools against the standards. The present study aims to dissect the national and international tools for WASH assessment in HCFs to suggest comprehensive WASH indicators. The databases like PubMed, Scopus, ScopeMed, Cochrane and Google Scholar were used to extract the available tools. The assessment process, methodology, and components of national and various international tools were compared and synthesized. A total of seven tools, namely WASH FIT 2, Facet, SARA, SPA, TOOL BOX-II, CDC and Kayakalp, were compared on eight components: water, sanitation, hand hygiene, healthcare waste, environmental cleaning and hygiene, infrastructure, workforce management, policy and protocols. Although most tools have covered the same indicators, the methodology and definitions differ. Few of the tools fail to capture the basic indicators defined by Joint Monitoring Programme (JMP). The critical indicators of policy and protocols are only covered in WASH FIT 2, Kayakalp, and TOOL BOX-II. Likewise, most tools fail to capture the indicator of cleaning, IPC practices and climate resilience. The present review also highlighted the limitations of selected tools regarding definitions, methodology and implementation. Hence, based on the review findings, a comprehensive short tool has been developed to monitor WASH in HCF of India. It comprises all the essential fundamental indicators identified from various tools, and recommended by the JMP service ladder with proper definitions. This tool can be helpful for hospital staff and managers for the routine monitoring of WASH in HCFs and improve the quality of care and IPC practices in HCFs.

ABSTRACT

The Prevention Technician in the Environment and Workplaces (PTEW) is a health professional who works in the identification, assessment, and management of risk in living and working places. The PTEW implements specific corrective actions at reducing exposure levels to chemicals such as formaldehyde. The aim of this report was to update the formaldehyde risk assessment document (RAD). The risk assessment process was divided into three steps as follows: (1) preliminary data collection, (2) an on-site visit to identify the use patterns and process, and (3) application of the algorithm to calculate the exposure levels of healthcare workers. In addition, with the introduction of closed-circuit systems, 23 devices were evaluated to identify possible airborne dispersion of formaldehyde. The algorithm was applied in 31 hospital units and the results allowed us to classify the staff in two levels of exposure for each hospital unit; healthcare workers were classified as "exposed" or "potentially exposed." Most of the HCWs are categorized as potentially exposed, and only workers working in laboratories are considered to be exposed. The results showed that devices must be used properly according to the user manual. To increase the level of worker safety, we have proposed to introduce closed-circuit safe handling systems and keeping the duration and intensity of exposure at the lowest possible levels according to the "ALARA" principle. The assignment of the Italian PTEW is to achieve excellence in the levels of health and safety of patients and hospital workers by pursuing a shared mission: improving the quality of public health.

ABSTRACT

Reports of plastics, at higher levels than previously thought, in the water that we drink and the air that we breathe, are generating considerable interest and concern. Plastics have been recorded in almost every environment in the world with estimates on the order of trillions of microplastic pieces. Yet, this may very well be an underestimate of plastic pollution as a whole. Once microplastics (<5 mm) break down in the environment, they nominally enter the nanoscale (<1,000 nm), where they cannot be seen by the naked eye or even with the use of a typical laboratory microscope. Thus far, research has focused on plastics in the macro- (>25 mm) and micro-size ranges, which are easier to detect and identify, leaving large knowledge gaps in our understanding of nanoplastic debris. Our ability to ask and answer questions relating to the transport, fate, and potential toxicity of these particles is disadvantaged by the detection and identification limits of current technology. Furthermore, laboratory exposures have been substantially constrained to the study of commercially available nanoplastics; i.e., polystyrene spheres, which do not adequately reflect the composition of environmental plastic debris. While a great deal of plastic-focused research has been published in recent years, the pattern of the work does not answer a number of key factors vital to calculating risk that takes into account the smallest plastic particles; namely, sources, fate and transport, exposure measures, toxicity and effects. These data are critical to inform regulatory decision making and to implement adaptive management strategies that mitigate risk to human health and the environment. This paper reviews the current state-of-the-science on nanoplastic research, highlighting areas where data are needed to establish robust risk assessments that take into account plastics pollution. Where nanoplastic-specific data are not available, suggested substitutions are indicated.

ABSTRACT

INTRODUCTION: Various research sites are pursuing 14 T MRI systems. However, both local SAR and RF transmit field inhomogeneity will increase. The aim of this simulation study is to investigate the trade-offs between peak local SAR and flip angle uniformity for five transmit coil array designs at 14 T in comparison to 7 T. METHODS: Investigated coil array designs are: 8 dipole antennas (8D), 16 dipole antennas (16D), 8 loop coils (8D), 16 loop coils (16L), 8 dipoles/8 loop coils (8D8L) and for reference 8 dipoles at 7 T. Both RF shimming and kT-points were investigated by plotting L-curves of peak SAR levels vs flip angle homogeneity. RESULTS: For RF shimming, the 16L array performs best. For kT-points, superior flip angle homogeneity is achieved at the expense of more power deposition, and the dipole arrays outperform the loop coil arrays. DISCUSSION AND CONCLUSION: For most arrays and regular imaging, the constraint on head SAR is reached before constraints on peak local SAR are violated. Furthermore, the different drive vectors in kT-points alleviate strong peaks in local SAR. Flip angle inhomogeneity can be alleviated by kT-points at the expense of larger power deposition. For kT-points, the dipole arrays seem to outperform loop coil arrays.

ABSTRACT

PURPOSE: The purpose of this study is to compare patient-reported voice handicap and auditory-perceptual measures of voice between healthy individuals and COVID-19 patients, as well as to investigate the effect of clinical factors on voice quality. METHODS: COVID-19 patients (n = 138) and 90 healthy controls were included in the study. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) was used to grade voice samples based on overall severity, roughness, breathiness, strain, pitch, and loudness. The Voice Handicap Index-10 was completed by all participants (VHI-10). Physical (pVHI), emotional (eVHI) and functional (fVHI) subscores were calculated. Clinical data were collected (disease stage, CT grade, neutrophil/lymphocyte ratio, CRP, and symptoms). RESULTS: A statistically significant difference between patient and control groups in VHI-10 and CAPE-V scores was detected (p < 0.001). Except eVHI, total score and all subscale scores were higher in patients with COVID-19 as the pVHI was the most affected (η2 = 0.324) subscale. All scores of CAPE-V were significantly worse in patients with COVID-19 as highest impact of COVID-19 was on breathiness (η2 = 0.518). Pre-existing pulmonary comorbidity, dyspnoea and N/L was significantly associated with the VHI-10 overall score (ßpc = 4.27, ßdyspnoea = 5.69 and ßnl = 0.25). The overall severity of CAPE-V was significantly dependent on dyspnoea and pulmonary comorbidity (ßdyspnoea = 11.25, ßpc = 10.12). VHI ≥4 and CAPE-V overall severity ≥11 were good indicators of COVID-19 related dysphonia. CONCLUSIONS: COVID-19 causes patient-reported voice handicap and deteriorates auditory-perceptual measures of voice. COVID-19 related voice impairment was mainly associated with the decreased respiratory capacity.

ABSTRACT

AIMS: Electrical reconnection of pulmonary veins (PVs) is considered an important determinant of recurrent atrial fibrillation (AF) after pulmonary vein isolation (PVI). To date, AF recurrences almost automatically trigger invasive repeat procedures, required to assess PVI durability. With recent technical advances, it is becoming increasingly common to find all PVs isolated in those repeat procedures. Thus, as ablation of extra-PV targets has failed to show benefit in randomized trials, more and more often these highly invasive procedures are performed only to rule out PV reconnection. Here we aim to define the ability of late gadolinium enhancement (LGE)-magnetic resonance imaging (MRI) to rule out PV reconnection non-invasively. METHODS AND RESULTS: This study is based on a prospective registry in which all patients receive an LGE-MRI after AF ablation. Included were all patients that-after an initial PVI and post-ablation LGE-MRI-underwent an invasive repeat procedure, which served as a reference to determine the predictive value of non-invasive lesion assessment by LGE-MRI.: 152 patients and 304 PV pairs were analysed. LGE-MRI predicted electrical PV reconnection with high sensitivity (98.9%) but rather low specificity (55.6%). Of note, LGE lesions without discontinuation ruled out reconnection of the respective PV pair with a negative predictive value of 96.9%, and patients with complete LGE lesion sets encircling all PVs were highly unlikely to show any PV reconnection (negative predictive value: 94.4%). CONCLUSION: LGE-MRI has the potential to guide selection of appropriate candidates and planning of the ablation strategy for repeat procedures and may help to identify patients that will not benefit from a redo-procedure if no ablation of extra-PV targets is intended.

ABSTRACT

Evidence is beginning to emerge of the serious negative effects online only child sexual abuse (OOCSA) can have on victims. Establishing the scale and nature of the problem could assist police in prioritizing suspects. In study 1, scoping review identified eleven studies that examined OOCSA's impact on victims. Five themes emerged from narrative review; definitional issues, a new normal, OOCSA grooming processes, comparisons with offline CSA, mechanisms between OOCSA and harm. In study 2, OOCSA national prevalence was estimated by applying 2.9% rate of OOCSA observed from original police data to a lower bound ("sexual communication with a child" crimes recorded by the police), middle (scaling up to estimate undetected offenses) and upper bound estimate of the national offender pool (self-reported sexual solicitation offenders). Recent UK Home Office figures were adapted to establish economic costs. Lifetime costs estimates attributable to OOCSA are £7.4 million (police reports), £59.6 million (including undetected offenders) and £1.4 billion (national prevalence estimates). Over 75% of this is non-financial costs borne by victims in terms of emotional harm and lost output. Government bears around 20% of the cost burden, mostly non-financial costs for police forces. Findings are discussed in relation to evidence-led recommendations for prioritization and wider police actions that can be taken to avoid the considerable economic and social burden associated with OOCSA offenses.

ABSTRACT

Objective:To evaluate and analyze the health status of the elderly from physical health, mental health and social health, so as to understand the health status and health service needs of rural elderly.Methods:A total of 263 elderly people aged 60 years and over(mean aged 70.9±7.9 years, 113 males and 150 females, 125 aged 60-69 years, 98 aged 70-79 years and 40 aged 80 years and over)in Nanwangkong Village, Shaozhuang Town, Qingzhou City, Weifang City, Shandong Province were selected by cluster sampling method.The physical, mental, social and overall health status of the elderly were comprehensively evaluated and analyzed by self-designed questionnaire.Results:The overall health rate was 30%(79 cases), and the physical health, mental health and social health rates were 73.8%(194 cases), 84.0%(221 cases)and 34.6%(91 cases), respectively, in rural elderly in this area.The physical health was better in males than in females in 80~ years old groups( χ2=5.736, P<0.05). The overall health was better in males than in females in the total age group and the 60~69 years old groups( χ2=7.468 and 11.116, both P<0.01). The proportions of unhealthy, basic healthy and healthy people in the overall and the dimensions of physical health, mental health and social health had significant differences in the 60~69, 70~79 and 80~ years old groups( χ2=40.590, 29.342, 18.503 and 27.615, all P<0.01), and the Chi-square test for trend showed that there was a statistically significant downward trend of overall health grade distribution with age( χ2=21.994, 12.831, 16.570 and 22.595, both P<0.01). Conclusions:In this study, 30.0% of the rural elderly were considered healthy, 48.3% were basically healthy, and 21.7% were unhealthy.The health status of the elderly gradually deteriorates with age.The government should strengthen the multidimensional health assessment of the rural elderly and provide the comprehensive health guidance services and targeted interventions for the elderly in terms of disease control, psychological counseling and social participation.
