PSXII-10 Non-invasive measurements of woody and normal condition in broiler breast meat

Woody Breast (WB) defines a quality issue resulting from a muscle abnormality in chicken meat, which makes the breast meat more rigid and sometimes pale in color with inferior texture. The frequency of this defect in Europe is over 30% and some have argued that similar levels may exist in the United States. Given that chicken with WB are of poor economic value and are discriminated by the consumers, producers face significant economic hardship under the current production paradigm. One of the problems in identifying the biological mechanism responsible for WB is that the occurrence and severity of WB can be only identified after harvest. This study is to investigate the physical characteristics of WB and normal breast (NB) in live chicken using a non-invasive, digital palpation device named as “MyotonPRO®”. This technology provides the measurements of superficial muscles regarding dynamic stiffness (100–1500 N/m; DS), elasticity (0.3–2.5), mechanical stress relaxation time (5–40 ms; MSRT) and ratio of deformation and relaxation time (0.3–2.5; RDRT). One hundred breast meat samples were used in this analysis (WB: 50; NB: 50), which were obtained from a local processing plant one day after harvest and sorted based on WB scoring with the naked eye (0, 1 for NB; 2, 3 for WB). One way ANOVA was used to analyze the data as a statistical model. The least squares means of the following variables were significantly different between WB and NB (P < 0.01): DS (603.4 vs 565.8; N/m), and elasticity (1.40 vs 1.55). However, MSRT and RDRT were not significantly different (P > 0.05). These results collectively show that the non-invasive measurements of WB differ from NB. The degree of muscle hardness in WB can be considered as a trait to be selected, and utilized for the genetic/genomic selection program collecting the measurements before harvest.

Intraoperative Lung Ultrasound (ILU) for the Assessment of Pulmonary Nodules

Background: The primary aim of this study was to confirm the validity of intraoperative lung ultrasound (ILU) as a safe and effective method of localization for difficult to visualize pulmonary nodules during Video-Assisted Thoracoscopic Surgery (VATS) and open thoracotomy. The secondary aim was to enhance knowledge on the morphological patterns of presentation of pulmonary nodules on direct ultrasound examination. Materials and methods: 131 patients with lung nodule and indication for surgery were enrolled. All patients underwent pre-operative imaging of the chest, including Chest Computed Tomography (CT) and Transthoracic Ultrasound (TUS), and surgical procedures for histological assessment of pulmonary nodules (VATS or open thoracotomy). Results: The identification of 100.00% of lung nodules was allowed by ILU, while the detection rate of digital palpation was 94.66%. It was not possible to associate any specific ILU echostructural pattern to both benign or malignant lesions. However, the actual histological margins of the lesions in the operating samples were corresponding to those visualized at ILU in 125/131 (95.42%) cases. No complications have been reported with ILU employment. Conclusions: In our experience, ILU performed during both open surgery and VATS demonstrated to be a reliable and safe method for visualization and localization of pulmonary nodules non previously assessed on digital palpation. In addition, ILU showed to allow a clear nodule’s margins’ definition matching, in most cases, with the actual histological margins.

Impactação dentária de caninos permanentes - consequências e relação com ortopedia funcional dos maxilares

Clinical experience and knowledge of normal growth and development of children, as well as radiographic studies of the dental eruption evolution, are important to supervise the maxillary permanent canine eruption. Clinical observations of signs and symptons such as digital palpation of the permanent canine bulges above the primary canine apex, on children of about nine years old, is a very important step for the diagnosis of ectopic eruption. Dentist may find more help with the early diagnosis, to avoid complications that are not so frequent to happen, but are still a burden such as traction and adjacent root tooth resorption.

Trending Breakthroughs in the Advances of Detection of Oral Premalignant and Malignant Lesions - A Review

Oral cancer is the sixth most common malignant tumour, and it is the leading cause of morbidity and mortality due to its capacity to spread and invade. Oral cancer occurs at a different rate in different areas of the world, ranging from 2 to 10 per 100,000 people each year. Oral cancer is prevalent in South Asian nations such as Sri Lanka, India, Pakistan, and Bangladesh. In India, the frequency is 7-17 per 100,000 people each year, with 75,000 - 80,000 new cases per year. Identifying oral cancer in its early stages has a significant impact on survival rates when compared to detecting it later. Despite this, almost half of all diagnosed patients die within five years. A variety of well-established cancer screening programmes have been demonstrated to lower the patient morbidity and mortality dramatically. Regular check-ups, which include a thorough inspection of the whole mouth, are critical for detecting malignant and pre-cancerous problems early on. Unfortunately, early detection of oral precancerous and cancerous lesions has proved difficult due to the lesions' asymptomatic nature, doctors' casual approach to benign lesions, and the fact that 50 % of patients had regional or distant metastases at the time of diagnosis. Oral cancer is one of the most common cancers that leads to defacement and death. Despite recent advancements in therapeutic modalities, the prognosis has not improved. Patient’s mortality rates are positively associated with the point of presentation, with 60 % of people diagnosed with late-stage illness. Early diagnosis is important for oral cancer patient’s survival rate, as it decreases morbidity and mortality. According to the World Health Organization, the bulk of oral cancer patients are diagnosed late in the disease's progression, with a mediocre 5 - year survival rate of 50 %. As a result, careful treatment of oral cancer necessitates early diagnosis and intervention. Surgical biopsy is the gold standard for medical purposes, but it requires clinical assistance. Other screening methods that are simple to use, non-invasive, and expensive are the norms for any test to be accepted as a histopathology choice. The older cancer diagnosis modalities took longer, had more inter-observer bias, and were less descriptive. A standard oral examination with digital palpation is used in traditional techniques of screening for oral possibly malignant illnesses and oral cancers. Conventional inspection has been shown to be a poor discriminator of oral mucosal lesions. A variety of visual aids have been developed to help clinicians spot anomalies in the oral mucosa and in recent years, scientific and clinical developments have aided in the early detection and treatment of this disease. This review reflects on some of the older diagnostic modalities and screening methods for oral cancer diagnosis, as well as some of the recent more sophisticated techniques.

Correlation of levator ani muscle strength measurement between Modified Oxford Grading Scale and perineometer on pelvic organ prolapse patient

Pelvic Organ Prolapse (POP) is a debilitating condition affecting about half of all women aged of more than 60 years globally. Reduced levator ani muscle strength in POP is associated with worse symptoms and prognosis. Measurement of levator ani muscle strength can be done with several tools such as perineometer and digital palpation. However, there is currently no study regarding conformity between tests. The aim of this study is to determine the correlation between tests in POP patients. An analytic observational study using cross sectional design was done to determine conformity between perineometer and digital examination using Modified Oxford Grading Scale (MOS) in Dr Cipto Mangunkusumo National General Hospital, Indonesia during the period of July, 2018 to June, 2020. Correlation between tests was determined using Spearman test. Cut-off of perineometer reading for each MOS score was also determined. A total of 110 subjects examined with both perineometer and digital palpation were recruited to the study. Positive correlation was observed between perineometer reading and Modified Oxford Grading Scale (r = 0.790, p < 0.001). According to the result, values between 0.01 – 9.64 cmH2O correspond to very weak pressure (MOS 1); 9.65 – 22.49 cmH2O represent weak pressure (MOS 2); 22.5 – 35.24 cmH2O represent moderate pressure (MOS 3); ≥ 35.25 cmH2O represent good pressure (MOS 4). There was a strong correlation between MOS and perineometer result for measuring levator ani strength in POP patients.

Ultrasound guidance versus conventional technique for radial artery puncture in septic shock patients: A pilot study

Background: Arterial puncture, for obtaining an analysis of blood gas, is an interventional procedure often performed in emergency departments and intensive care units. This study compares the ultrasound (US) guided method with the conventional digital palpation method in radial artery puncture (RAP) for blood gas analysis in septic shock patients. Methods: This is a prospective, single-centre study. Septic shock patients over 18 years of age who needed a RAP sample for blood gas analysis were included. Patients with local infection or trauma at the puncture site, arteriovenous fistula, vascular graft, coagulopathy, a positive Allen test, or did not want to participate were excluded. Patients were randomized into two groups and RAP was obtained with either the US-guided method or the conventional method. The main outcomes were success at first entry, the number of attempts before success, and the time to success. Results: The 50 eligible patients were randomized into two groups. First entry success rate for the US-guided group and the conventional group was 80% and 42%, respectively. The number of attempts before success and time to success was significantly higher in the conventional group. Conclusion: The US-guided method has been found to be more successful in terms of first entry success, the number of attempts before success, and the time to success when compared to the conventional method.

Diurnal variations in the expression of core-clock genes correlate with resting muscle properties and predict fluctuations in exercise performance across the day

ObjectivesIn this study, we investigated daily fluctuations in molecular (gene expression) and physiological (biomechanical muscle properties) features in human peripheral cells and their correlation with exercise performance.Methods21 healthy participants (13 men and 8 women) took part in three test series: for the molecular analysis, 15 participants provided hair, blood or saliva time-course sampling for the rhythmicity analysis of core-clock gene expression via RT-PCR. For the exercise tests, 16 participants conducted strength and endurance exercises at different times of the day (9h, 12h, 15h and 18h). Myotonometry was carried out using a digital palpation device (MyotonPRO), five muscles were measured in 11 participants. A computational analysis was performed to relate core-clock gene expression, resting muscle tone and exercise performance.ResultsCore-clock genes show daily fluctuations in expression in all biological samples tested for all participants. Exercise performance peaks in the late afternoon (15–18 hours for both men and women) and shows variations in performance, depending on the type of exercise (eg, strength vs endurance). Muscle tone varies across the day and higher muscle tone correlates with better performance. Molecular daily profiles correlate with daily variation in exercise performance.ConclusionTraining programmes can profit from these findings to increase efficiency and fine-tune timing of training sessions based on the individual molecular data. Our results can benefit both professional athletes, where a fraction of seconds may allow for a gold medal, and rehabilitation in clinical settings to increase therapy efficacy and reduce recovery times.
