Effects of intermittent lighting program and light colour on ocular health variables as welfare indicators in broiler chickens.

1. The objective of the present study was to examine the effect of lighting programs and light colour on ocular health variables as welfare indicators in Ross 308 broilers.2. A total of 384, male, one-d-old broiler chickens (Ross 308) were placed in a completely randomised design with a 2 × 2 factorial arrangement of lighting program (continuous or intermittent) and light colour (white and green LED light). Ross 308 broilers under restricted lighting had 18 h of light (18 L:6D), while those under intermittent lighting had cycles of 17 L:3D:1 L:3D throughout the experimental period, which lasted 42 d.3. At the end of the experiment, all eyes of birds (n = 96 birds) underwent a complete ophthalmic examination, which included the Schirmer tear test I, intraocular pressure and eye dimensions. In addition, 32 broilers (eight birds per trial groups) aged 42 d underwent ophthalmic examination to include assessment of ocular ultrasound biometry.4. Light colour had a significant influence on the mean intraocular pressure (p < 0.001). The Ross 308 broilers kept with intermittent lighting had lower eye weights (2.29 g; p < 0.05), palpebral fissure length (14.39 mm; p < 0.01), eye dorsoventral diameter (17.46 mm; p < 0.05), anteroposterior size (13.70 mm; p < 0.01) and corneal dorsoventral diameter (7.81 mm; p < 0.05) compared to those reared under restricted lighting.5. In conclusion, these values for Ross 308 broilers may be applied in poultry ophthalmology to detect early eye disease symptoms and to help the diagnosis of tear disorders that could cause economic losses and welfare issues. Intermittent lighting and green LED light may help reduce eye health problems thus contributing to improved welfare in broilers.

Does in-brace correction affect coronal spinal and thoracic cage parameters in individuals with idiopathic scoliosis? A retrospective cohort study.

The aim of the study is to identify the effects of in-brace correction on coronal spinal and thoracic cage parameters in individuals with idiopathic scoliosis (IS). The coronal spinal parameters [Cobb angle, apical vertebral rotation (AVR), lateral trunk shift, coronal alignment, biacromial slope and pelvic asymmetry] and the thoracic cage parameters [T1- 12 height, T1-S1 height, thoracic transverse diameter, and apical vertebral body-rib ratio (AVB-R)] of 89 child and adolescent patients were measured on posterior-anterior full-spine radiographs at pre-brace and in-brace conditions using Surgimap software. The initial in-brace correction (IBC) was calculated as a percentage decrease in the Cobb angle on the in-brace radiographs. The mean IBC rate for the primary curve was 37% (range = 10-100%). In the in- brace condition, the Cobb angle (p<0.001), AVR (p<0.001) and lateral trunk shift (p<0.001) decreased significantly; no statistically significant difference was found in the biacromial slope (p=0.713) and the coronal alignment (p=0.074). The T1-12 height and the T1-S1 height increased significantly (p<0.001) whereas the thoracic transverse diameter and the AVB-R decreased significantly (p<0.001). Unlike IBC rate was below 30% as IBC rate was above 30%, the T1-12 height (p<0.001) increased and the AVB-R decreased (p<0.001). The bracing improved the lateral trunk shift, the AVB-R, the thoracic and spine heights, but decreased the thoracic transverse diameter. The thoracic cage parameters may be better when the IBC rate is above 30%.

PITUITARY FUNCTIONS AFTER RECOVERY FROM COVID-19.

Context: Injury and functional disorders in pituitary gland after COVID-19 still need elucidation. Objective: To investigate pituitary functions, particularly hypothalamic pituitary adrenal (HPA) axis after COVID-19 infection. Methods: This study was conducted at a university hospital between May and October 2021. Patients who had COVID-19, were enrolled as study group, three months after recovery. Participants who do not have COVID-19 diagnosis, with similar characteristics were included as control group. Blood samples were taken on the morning at 08 AM. Adrenal stimulation test was performed with 1 µg of ACTH (Synacthen). Results: The study group included 50 patients and control group was 49 cases. One (2%) out of the 50 patients with 8 a.m. serum cortisol below 5 µg/dL. Low serum ACTH levels were detected in 7 (14%) participants in patient group. Stimulation with 1 µg of ACTH (Synacthen) test was performed for 2 (4%) of 50 patients with serum cortisol below 10 µg/dL. Both patients achieved a peak cortisol of over 12.5 µg/dL after stimulation. Standard deviation (SD) score for insulin like growh factor-1 (IGF-1) was lower than -2 SD for age and gender in 7 (14%) patients. TSH levels was mildly increased in five (10%) patients. There was no significant difference in baseline pituitary hormone levels in study and control groups. Conclusion: Basal pituitary hormone levels and HPA axes were found to be preserved and competently functioning in patients who experienced mild/moderate COVID-19. However, symptoms observed after COVID-19 episode were evident in substantial amount of patients in this study and these symptoms were not associated with changes in pituitary gland function.

Effects of barrier perch access and early dietary protein and energy dilution on some welfare parameters, tibiotarsus measurements, fear and mobility level in broiler chickens.

1. This experiment determined the effect of increasing mobility in broiler chickens by placing barrier perches between feeders and drinkers. In addition, the limitation of early weight gain by dietary energy and protein dilution on some welfare parameters, tibiotarsus measurements, fear and mobility level was examined.2. A total of 504 male, one-day-old broiler chickens (Ross 308) were randomly allocated to four treatments with three replicate pens per treatment and 42 broiler chickens per pen as a 2 × 2 factorial arrangement. Treatments included feeding the basal control diet between 0-42 days or a diet diluted by 10% energy and 20% crude protein fed between 0-21 d, with the control diet fed between 22-42 d. The second factor was the presence or absence of barrier perches. All treatments were allocated as a completely randomised design. Welfare parameters (foot pad dermatitis, hock burn, gait score, feather score, breast blister), tibiotarsus measurements (bone mineral content, bone mineral density, fluctuating asymmetry and relative fluctuating asymmetry), tonic immobility and mobility level were recorded.3. Results showed that access to a barrier perch and the diluted diet increased the mobility in broiler chickens. However, access to a barrier perch had no significant effect on tibiotarsus and welfare parameters. Broiler chickens had better gait scores (P < 0.05) and lower foot pad dermatitis incidence (P < 0.01) in groups fed the diluted diet. The diluted diet had no significant effect on bone mineral density but reduced the tibiotarsus bone mineral content (P < 0.05).4. In conclusion, the diluted diet provided positive effects in terms of leg health due to weight gain limitations in the early period, thus improving broiler chicken welfare.

The Use of Dynamic Cognitive Behavioural Therapy (DCBT) in Social Anxiety Disorder (SAD): A Theoretical Integration Initiative.

Psychotherapy theorists can often become fervent advocates of the schools they follow and place the doctrines of the theories they adopt above all else. This situation can sometimes turn into a war of theories between researchers as well. However, therapists should not aim to shape therapy sessions according to their methods but to use them in line with clients' needs. Although it is emphasised that the integration of both psychoanalytic and cognitive behavioural therapy techniques, which is going to be named dynamic cognitive behavioural therapy (DCBT) in this case report, will provide more effective and permanent treatment, a discernible gap exists regarding the integration of these theories and their use in psychotherapy. Taking into account this gap, it is considered important to use this approach with a client who has a social anxiety disorder (SAD). Therefore, this study aims to describe the almost forgotten DCBT approach step by step through a case report and reveal the effectiveness of this approach. As a result, DCBT seems to be effective in the treatment of SAD.

Hip dislocation based on Developmental Dysplasia of the Hip (DDH) in a patient with Giant Congenital Melanocytic Nevus (GCMN): A rare coexistence.

Giant congenital melanocytic nevus (GCMN) is a rare congenital benign neoplasm with the potential to become malignant. Various extracutaneous malformations may accompany GCMN. Acetabular dysplasia accompanying GCMN was described in previous studies. To the best of our knowledge, this case report of ours is the first reported case of GCMN diagnosed and treated with hip dislocation based on developmental dysplasia of the hip (DDH). The rare coexistence prompted us to report this case.

The relationship of psychological status and sociodemographic factors with bruxism among undergraduate dental students: A national survey.

Background: Although its etiology is not fully known, the accepted view is that bruxism is a multifactorial disorder. Aims: This study aims to evaluate the prevalance of self-reported bruxism and to investigate its relationship with psychological and sociodemographical factors amongst undergraduate dental students in Zonguldak, Turkey. Subjects and Methods: 250 dental students were asked to fill the bruxism questionnaire - to detect the prevelance of bruxism; personal information form - to determine sociodemographic variables; and symptom checklist-90-R (SCL-90-R) - to asses psychological state. Data were analyzed statistically by Kolmogorov Smirnov, Shapiro Wilk, Mann Whitney U, and Kruskal Wallis tests through Statistical Package for the Social Sciences (SPSS) program. Results: The prevalance of self-reported bruxism was 40%. 46% of the students showed higher levels of psychological symptoms. SCL-90-R subscales showed statistically significant differences in students with bruxism compared to those without bruxism (P < 0.05). It was observed that bruxism was associated with gender (P < 0.05) and both bruxism and psychological symptom levels were statistically higher in females (P < 0.05). Conclusions: The findings revealed that, although bruxism was common among dental students, gender and psychosocial factors are also mostly associated with the etiology of bruxism. In this context, during the challenging dentistry education period, it is important to direct students who are found to have high levels of psychological symptoms to psychological counseling and guidance services.

Role and limitations of high-flow nasal oxygen therapy in COVID-19 patients: An observational study.

Background: The management of acute respiratory failure in COVID-19 patients and the role and limitations of high-flow nasal oxygen therapy (HFNOT) remain unclear. Aim: This study aimed to investigate the effect of HFNOT, identify the characteristics of patients who will benefit from therapy, and determine monitoring strategies to decide on endotracheal intubation for patients with COVID-19. Patients and Methods: We conducted a prospective observational study of COVID-19 patients who were admitted to the intensive care unit (ICU) and required HFNOT for at least 2 days between 20 March 2020 and 20 June 2020. The exclusion criteria were a severe respiratory failure, reduced levels of consciousness, combination with other noninvasive ventilation strategies, and exhaustion. The patients were followed up until ICU discharge. The primary outcome was the proportion of patients with COVID-19 who were successfully weaned from HFNOT, whereas failure comprised intubation or death on HFNOT. Results: Thirty-five subjects (24 males, mean-age: 61.62, standard deviation: 14.9 yr.) were included in the study. A total of 20/35 (57.1%) subjects survived to discharge. C-reactive-protein (CRP) and interleukin-6 (IL-6) levels were significantly increased in the treatment failure group (CRP; effect size (r):0.35, P: 0.037, IL-6; r: 0.37, P: 0.03). Although there was a difference between repeated measures of partial-pressure-of-oxygen/fraction-of-inspired-oxygen (PaO2/FiO2:P/F) rates (partial-eta-squared (ηp2):0.79, P < 0.001), no difference was found between carbon dioxide levels (ηp2:0.29, p: 0.44). There was also no difference between ROX (ratio-of-oxygen-saturation/FiO2 to respiratory-rate) rates (Kendall's W: 0.33 P = 0.310). Conclusion: In COVID-19 patients with mild-to-moderate dyspnea and hypoxemia who are nonresponsive to conventional-oxygen-therapies, the initial approach may involve the use of HFNOT. In this study, patient monitoring could be performed with ROX and P/F ratios, and the effectiveness of the treatment could be decided by looking at these rates in the second hour. Prolongation of the period and awake prone positioning did not improve the outcome.

A retrospective analysis of intensive care unit patients during the pandemic period.

aimed to evaluate the laboratory parameters, risk factors, and success in predicting mortality in COVID-19 patients admitted to our hospital's intensive care units (ICUs). METHODS: Levels of procalcitonin, ferritin, D-dimer, CRP and albumin measured on days 1 and 7 were recorded. Patients were divided into two groups as non-survivors and patients, who were discharged from ICUs. The predictive values of laboratory parameters in predicting COVID-19 mortality were investigated. RESULTS: A statistically significant difference was detected between the two groups in the mean values of all laboratory parameters tested on days 1 and 7, including D-dimer, procalcitonin, CRP, WBC, ferritin (excluding only D-dimer levels and WBC counts on day 1; p=0.061 and p=0.243, respectively) (p<0.001, p<0.001, p<0.001, p=0.013, p<0.001, p<0.001, p<0.001, p<0.001, p<0.001, p<0.001; respectively). CONCLUSION: . It can be argued that procalcitonin, ferritin, and D-dimer can be guiding parameters in predicting mortality in COVID-19 because their levels were found to be significantly higher in non-survivors. D-dimer, procalcitonin, and ferritin showed an almost high level of sensitivity and specificity in predicting mortality (Tab. 5, Fig. 3, Ref. 19).

Potential therapeutic road for targeting the SARS-CoV-2 at throat.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) has become a serious public health problem for    183 out of 197 countries in the world. Understanding the routes and pathogenesis of the coronavirus is important and it is considered that the studies on host cell receptor Angiotensin Converting Enzyme 2 (ACE2) may be valuable for the treatment and prevention of the disease. AIM: To evaluate the possibility of inhibition of SARS-CoV-2 at throat. METHODS: A comprehensive literature search was conducted. CONCLUSION: In view of the fact that the mouth and nose have higher number of ACE2 expressed cells, they serve as a gateway for the virus to enter. Thus, blocking the gate could be a good choice to reduce or even prevent the transmission. Small interfering RNAs (siRNAs) are double-stranded RNA molecules and could be designed easily and directed against many strains of a virus. Due to their features, siRNAs can provide a potential strategy to interfere with the replication of viral diseases. We think that since oral and nasal epithelial cells are relatively easily accessible it may allow to develop siRNA molecules to inhibit SARS-CoV-2 already at the entry where it continues to replicate for a period (Fig. 1, Ref. 50).

Cross-sectional imaging and laparoscopic findings of diaphragmatic mesothelial cysts.

AIM: To present cross-sectional imaging, surgical findings, and follow-up results of diaphragmatic mesothelial cysts. MATERIALS AND METHODS: Radiological findings for location, size, shape, and internal structure of cysts were reviewed retrospectively. For patients that underwent surgery, surgical reports and laparoscopy images were reviewed. In conservatively managed patients, changes in size and imaging findings of the cyst were assessed during follow-up visits. RESULTS: A total of 13 paediatric cases with an imaging and/or pathological diagnosis of diaphragmatic mesothelial cyst were identified. In all cases, the cystic lesions were located between the diaphragm and the posterolateral aspect of the right lobe of the liver. Eleven lesions (84.6%) had a bi-lobulate shape. Eight of these cases underwent laparoscopic cyst aspiration/unroofing. The postoperative course was uneventful and there were no cases of recurrence. The remaining five cases were managed conservatively with follow-up available in four cases. In three cases (75%), there was reduction in the size of the cysts with a mean volume reduction of 55%. CONCLUSION: Diaphragmatic mesothelial cysts are congenital cystic lesions that are usually detected incidentally. A common pitfall is incorrect interpretation of the lesion as a hepatic cyst. Conservative management with imaging follow-up can be adopted in asymptomatic cases with typical imaging findings.

Internet of Measurement Things Architecture: Proof of Concept with Scope of Accreditation.

Many industries, such as manufacturing, aviation, and power generation, employ sensitive measurement devices to be calibrated by certified experts. The diversity and sophistication of measurement devices and their calibration needs require networked and automated solutions. Internet of Measurement Things (IoMT) is an architectural framework that is based on the Industrial Internet of Things for the calibration industry. This architecture involves a layered model with a cloud-centric middle layer. In this article, the realization of this conceptual architecture is described. The applicability of the IoMT architecture in the calibration industry is shown through an editor application for Scope of Accreditation. The cloud side of the implementation is deployed to Microsoft Azure. The editor itself is created as a cloud service, and IoT Hub is used to collect data from calibration laboratories. By adapting the IoMT architecture to a commonly used cloud platform, considerable progress is achieved to encompass Metrology data and serve the majority of the stakeholders.

Sonoelastographic evaluation of the masseter muscle before and after mandibular setback surgery.

AIMS: The purpose of this study is to compare the thickness and elasticity of the masseter muscle before and after orthognathic surgery in patients with class III skeletal deformity and to investigate the relationship between the sonographic changes in the masseter muscle and the amount of mandibular setback. SUBJECTS AND METHODS: The study group consisted of 14 patients with skeletal class III malocclusions who had orthognathic surgery. The control group consisted of 14 patients who had dental and skeletal class I occlusion. Muscle thickness measurements were performed with B-mode and high-frequency linear scanning probe of the ultrasound device. Elastography feature and muscle hardness ratio were obtained by applying compression and decompression on muscles at rest and during maximum contraction in the transverse plane. Patients were categorized into two groups according to the mandibular setback as <5 mm and ≥5 mm. RESULTS: The masseter muscle thickness after surgery was found statistically increased bilaterally in both at rest and during contraction for the study group (P < 0.05). No difference was found between preoperative orthognathic measurements and postoperative measurements for elasticity index ratio measurements (P > 0.05). CONCLUSION: We believe that in the present study important findings have been emphasized for further research aiming to investigate the possible relationship between masticatory alterations and surgical outcomes after orthognathic surgery.

Postoperative analgesia after total abdominal hysterectomy: Is the transversus abdominis plane block effective?

BACKGROUND: Analgesic protocol is needed following gynecologic surgery to ensure early mobilization, decrease the duration in the post-anesthetic care unit and hospitalization, and provide patient comfort. Transversus abdominis plane (TAP) blocks are used in the treatment of acute postoperative pain after lower abdominal surgery. TAP block may be a better choice of postoperative pain control. In the present study, the efficacy of ultrasound-guided TAP block on pain control and postoperative opioid consumption was evaluated in patients undergoing a total abdominal hysterectomy. METHODS: Fifty patients undergoing total abdominal hysterectomy were included in this study. Patients were divided into TAP block (n = 25) and control groups (n = 25). Both groups postoperative patient-controlled analgesia (PCA) was planned during 24 h postoperatively. Patients were assessed 1, 2, 4, 6, 12, 18, and 24 h postoperatively using the Visual Analog Scale (VAS), Ramsey Sedation Score, PCA demand, morphine consumption, first analgesic requirement time, and adverse reactions. RESULTS: When compared with the control group, the time to first analgesic requirement in the TAP block group was significantly lower (P < 0.05). The amount of additional analgesia also differed significantly (P < 0.001). In the TAP group, the VAS was significantly lower at 2, 4, 6, 12, 18, and 24 h postoperatively compared to the control group (P < 0.05). There was no statistically significant difference in adverse reactions. CONCLUSION: TAP block can effectively treat postoperative pain as part of multimodal analgesia in patients undergoing total abdominal hysterectomy.

Two-colour chewing gum mixing ability test for evaluating masticatory performance in children with mixed dentition: validity and reliability study.

The unappealing taste of the chewing material and the time-consuming repetitive task in masticatory performance tests using artificial foodstuff may discourage children from performing natural chewing movements. Therefore, the aim was to determine the validity and reliability of a two-colour chewing gum mixing ability test for masticatory performance (MP) assessment in mixed dentition children. Masticatory performance was tested in two groups: systemically healthy fully dentate young adults and children in mixed dentition. Median particle size was assessed using a comminution test, and a two-colour chewing gum mixing ability test was applied for MP analysis. Validity was tested with Pearson correlation, and reliability was tested with intra-class correlation coefficient, Pearson correlation and Bland-Altman plots. Both comminution and two-colour chewing gum mixing ability tests revealed statistically significant MP differences between children (n = 25) and adults (n = 27, both P < 0·01). Pearson correlation between comminution and two-colour chewing gum mixing ability tests was positive and significant (r = 0·418, P = 0·002). Correlations for interobserver reliability and test-retest values were significant (r = 0·990, P = 0·0001 and r = 0·995, P = 0·0001). Although both methods could discriminate MP differences, the comminution test detected these differences generally in a wider range compared to two-colour chewing gum mixing ability test. However, considering the high reliability of the results, the two-colour chewing gum mixing ability test can be used to assess masticatory performance in children, especially at non-clinical settings.

Changes in irisin levels in patients with hyperemesis gravidarum.

PURPOSE: The aim of this study was to compare levels of serum irisin in hyperemesis gravidarum (HG) patients to healthy gravidas. MATERIALS AND METHODS: Twenty pregnant women with hyperemesis gravidarum (Group 1) and 20 healthy pregnant women (Group 2) all of similar ages, body mass index, and all at similar pregnancy development comprised the study cohort. Fasting serum samples were obtained and measured for irisin levels. Comparisons between groups were done by Mann Whitney U (MWU) test and p < 0.05 was considered as statistically significant. RESULTS: All the patients in groups 1 and 2 were primigravid and age, gestational week, and body mass index values were similar. No statistically significant difference were present among these parameters (p > 0.05, MWU test). The plasma irisin concentrations in group 1 were significantly higher (irisin (average ±S D): 116.9 ± 32.3 ng/ml vs. 87.7 ± 26.2 ng/ml) compared to the control group. CONCLUSION: This study suggests a possible role of irisin, which might be involved in the pathology of HG.

Masticatory parameters of children with and without clinically diagnosed caries in permanent dentition.

AIM: Mastication turns food into a bolus and prepares it for chemical digestion. Any condition affecting tooth structure and position may have an impact on mastication. The aim of this study is to compare masticatory performance (MP) and maximum bite force (MBF) between children with and without clinically visible caries in permanent first molars. MATERIALS AND METHODS: The study was conducted with 50 children in good general condition aged 12-14 years (25 girls, 25 boys) with no orthodontic/skeletal anomalies and no missing teeth due to dental trauma or extraction. Maximum bite force was measured bilaterally using strain gauge sensors. Masticatory performance was evaluated by silicone tablet comminution test. RESULTS: Masticatory performance was superior in caries-free children when compared to children with caries. Maximum bite force values in children with and without caries were not statistically different. CONCLUSIONS: Caries reduces masticatory performance. Therefore, treatment is crucial for masticatory efficiency.

Role of anatomic variations of paranasal sinuses on the prevalence of sinusitis: Computed tomography findings of 350 patients.

OBJECTIVE: The aim of this study was to determine the frequency of anatomic variations of the paranasal sinuses and their roles in the development of sinusitis. MATERIALS AND METHODS: Computed tomography of paranasal sinuses of 350 patients was assessed in terms of anatomic variations and inflammatory sinus pathology. The coexistence of anatomic variations with sinusitis was statistically investigated. RESULTS: At least one anatomical variation of paranasal sinuses was detected in 325 patients (92.9%). In 297 (91.4%) of these patients, sinusitis was observed at rates varying depending on the types of anatomic variations. A statistically significant relationship was found between agger nasi cells, Onodi cells, hypertrophy of middle concha, concha bullosa, uncinate bulla, and the medial and lateral deviations of uncinate process and sinusitis. On the other hand, there was no statistically significant relationship between septal deviation, paradoxical middle concha, secondary middle concha, great ethmoidal bulla, and sinusitis. CONCLUSION: Certain types of paranasal sinus variations create a susceptibility to sinusitis.

The relation between monocyte to HDL ratio and no-reflow phenomenon in the patients with acute ST-segment elevation myocardial infarction.

BACKGROUND: No-reflow phenomenon is a prognostic value in ST-segment elevation myocardial infarction (STEMI). Monocyte to high density lipoprotein ratio (MHR) has recently emerged as a marker of inflammation and oxidative stress in the cardiovascular disease. PURPOSE: In this study, we aimed to investigate the relation between MHR and no-reflow phenomenon in patients with STEMI undergoing primary percutaneous coronary intervention (pPCI). MATERIAL AND METHODS: A total of 600 patients with STEMI (470 men; mean age, 62 ± 12 years) admitted within 12 hours from symptom onset were included into this study. Patients were classified into 2 groups based on postintervention Thrombolysis in Myocardial Infarction (TIMI) flow grade: no-reflow-TIMI flow grade 0, 1, or 2 (group 1); angiographic success-TIMI flow grade 3 (group 2). RESULTS: According to admission whole-blood cell count results, the patients in the no-reflow group had significantly higher monocyte count and MHR values when compared with those of the reflow patients. After multivariate backward logistic regression, MHR remained independent predictors of no reflow after pPCI. Adjusted odds ratios were calculated as 1.09 for MHR (P< .001; confidence interval [CI], 1.07-1.12). Receiver operating characteristic curve analysis suggested that the optimum MHR level cutoff point for patients with no-reflow was 22.5, with a sensitivity and specificity of 70.2% and 73.3%, respectively (area under curve, 0.768; 95% CI, 0.725-0.811). CONCLUSION: In conclusion, MHR levels are one of the independent predictors of no reflow in patients with STEMI after pPCI.
