Objective: Considering the importance of dairy farming and the negative effects of heat stress, more tolerant genotypes need to be identified. The objective of this study was to investigate the effect of heat stress via temperature-humidity index (THI) and diurnal temperature variation (DTV) in the genetic evaluations for daily milk yield of Holstein dairy cattle, using random regression models. Methods: The data comprised 94,549 test-day records of 11,294 first parity Holstein cows from Brazil, collected from 1997 to 2013, and bioclimatic data (THI and DTV) from 18 weather stations. Least square linear regression models were used to determine the THI and DTV thresholds for milk yield losses caused by heat stress. In addition to the standard model (SM, without bioclimatic variables), THI and DTV were combined in various ways and tested for different days, totaling 41 models. Results: The THI and DTV thresholds for milk yield losses was THI = 74 (-0.106 kg/d/THI) and DTV = 13 (-0.045 kg/d/DTV). The model that included THI and DTV as fixed effects, considering the two-day average, presented better fit (-2logL, Akaike information criterion, and Bayesian information criterion). The estimated breeding values (EBVs) and the reliabilities of the EBVs improved when using this model. Conclusion: Sires are re-ranking when heat stress indicators are included in the model. Genetic evaluation using the mean of two days of THI and DTV as fixed effect, improved EBVs and EBVs reliability.

Objective This study aimed to evaluate patient-reported satisfaction following robot-assisted hysterectomy due to benign uterine disease, and to identify the factors associated. Methods We used a questionnaire to evaluate patients' satisfaction with robot-assisted hysterectomy. The questions concerned overall patient-reported satisfaction and specific factors affecting satisfaction, including postoperative pain, return to daily life, the hospital experience, wounds, cost, the doctor-patient relationship, whether expectations were met, and whether detailed information was provided. We also collected data from patient records, such as uterine weight, rate of pelvic adhesion, operation time, rate of transfusion, delayed discharge, and readmission. One hundred patients who underwent robot-assisted hysterectomy participated in the study. Seventy-three fully completed questionnaires were returned. Results The majority of patients (95.9%) were satisfied with robot-assisted hysterectomy. The doctor-patient relationship, whether expectations were met, the hospital experience, wounds, and whether detailed information was provided were statistically significant factors influencing patients' overall satisfaction. Payment of fees and clinical and surgical outcomes did not significantly influence patients' overall satisfaction. Conclusion Our findings show that most patients reported high levels of satisfaction following robot-assisted hysterectomy, regardless of cost or clinical and surgical outcomes. Therefore, if gynecologists consider robot-assisted hysterectomy suitable for patients they need not hesitate based on potential costs; they should feel confident in recommending the procedure to patients.

Background: Although the zygomatic arch is an important structure determining facial prominence and width, no consensus exists regarding the classification of isolated zygomatic arch fractures, and the literature on this topic is scarce. To date, five papers have subdivided zygomatic arch fractures; however, only one of those proposed classifications includes the injury vector, although the injury vector is one of the most important factors to consider in fracture cases. Furthermore, the only classification that does include the injury vector is too complicated to be suitable for daily practice. In addition, the existing classifications are clinically limited because they do not consider greenstick fractures, nondisplaced fractures, or coronoid impingement. In the present study, we present a rearrangement of the previously published classifications and propose a modified classification of isolated zygomatic arch fractures that maximizes the advantages and overcomes the disadvantages of previous classification systems. Methods: The classification criteria for isolated zygomatic arch fractures described in five previous studies were analyzed, rearranged, and supplemented to generate a modified classification. The medical records, radiographs, and facial bone computed tomography findings of 134 patients with isolated zygomatic arch fractures who visited our hospital between January 2010 and December 2019 were also retrospectively analyzed. Results: We analyzed major classification criteria (displacement, the force vector of the injury, V-shaped fracture, and coronoid impingement) for isolated zygomatic arch fracture from the five previous studies and developed a modified classification by subdividing zygomatic arch fractures. We applied the modified classification to cases of isolated zygomatic arch fracture at our hospital. The surgery rate and injury severity differed significantly from fracture types I to VI. Conclusion: Using our modified classification, we could determine that both the injury force and the injury vector meaningfully influenced the surgery rate and the severity of the injuries.

Background: Neurolytic celiac plexus block (NCPB) is a typical treatment for severe epigastric cancer pain, but the therapeutic effect is often affected by the variation of local anatomical structures induced by the tumor. Greater and lesser splanchnic nerve neurolysis (SNN) had similar effects to the NCPB, and was recently performed with a paravertebral approach under the image guidance, or with the transdiscal approach under the guidance of computed tomography. This study observed the feasibility and safety of SNN via a transdiscal approach under fluoroscopic guidance. Methods: The follow-up records of 34 patients with epigastric cancer pain who underwent the splanchnic nerve block via the T11-12 transdiscal approach under fluoroscopic guidance were investigated retrospectively. The numerical rating scale (NRS), the patient satisfaction scale (PSS) and quality of life (QOL) of the patient, the dose of morphine consumed, and the occurrence and severity of adverse events were recorded preoperatively and 1 day, 1 week, 1 month, and 2 months after surgery. Results: Compared with the preoperative scores, the NRS scores and daily morphine consumption decreased and the QOL and PSS scores increased at each postoperative time point (P < 0.001). No patients experienced serious complications. Conclusions: SNN via the transdiscal approach under flouroscopic guidance was an effective, safe, and easy operation for epigastric cancer pain, with fewer complications.

Objective: The objective of this randomized clinical trial was to study the skeletal and dental effects of low-level laser therapy (LLLT) along with a miniscrew-assisted expander (Hyrax) after six months of retention. Methods: After sequence generation, concealed allocation, and implementation, 24 female patients were randomly divided (1:1) into two-groups: bone-borne rapid palatal expansion (BBE) without LLLT (n = 12) and BBE with LLLT (n = 12). Eligibility criteria included female patients aged 10-13 years old with bilateral posterior crossbites. Intraoral and extraoral photographs, cone-beam computed tomography images, and digital study models were obtained before expansion and six months after retention. The 7 mm Hyrax appliance was anchored to four palatal mini-screws, which were activated twice daily for 15 days, then locked and kept in place as a retainer. LLLT was performed in the laser group during expansion and retention, according to the guidelines provided. Results: The records of 24 patients were analyzed. According to the post-retention measurements, both groups showed a significant increase in nasal and maxillary widths and total facial height. In the laser group, the Sella-Nasion-Point A and Point A-Nasion-Point B angles and the interpremolar apical distance were significantly increased. Conclusions: Within the limitations of this study, the results suggest that the parameters and protocol of LLLT do not clinically affect the efficiency of BBE in prepubertal and pubertal patients.

Interest in Edutech increased rapidly during the pandemic. In a situation where face-to-face classes are impossible, Edutech has become an important issue for schools and the public. Therefore, this study reviewed newspaper articles in Edutech of major daily newspapers nationwide, analyzed the main contents, characteristics, and issues of discourse on this, and explored tasks. Edutech discourse initially emphasized most of its usefulness as an educational tool, but new issues emerged during the pandemic. Beyond the use of new technology, how to induce and sustain learners' will become an issue and remain a task. In addition, as a public education, securing fairness in school records and evaluations and protecting the personal information of related people became sensitive issues. In applying Edutech, the problem of preferential treatment for any technology company has also become controversial. This issue is an area other than technology, but it remains a task in the edutech problem.

This case study tried to explore the food insecurity experiences of poor households with children, since 'food insecurity experiences' of poor households represents economic inequality and social deprivation in the midst of a affluent society. Interviewees in this reports reported that they have found difficulties with buying right or enough food materials due to short of income. As well, they have usually experienced the selection and use of only low-grade foods, substitution for more cheap food materials, limitation of available food materials(especially, meats and fruits), and monotonous diets in their everyday lives. Sometimes, their children skipped their meals due to their monotonous diets. To sum up, I could identify that they(poor households with children) had experienced many components of 'food insecurity' constructs in their daily lives. In spite of, there are some distinction between reports through food insecurity scale and records of interviews and the various foods-supply programs have supplemented their food insecure situation. Therefore, we should give consideration to these in the use and interpretation of the results of food insecurity scales.

Purpose: This study aims to investigate factors related to long-term length of stay (LOS) of patients with chronic diseases in Korean veterans hospitals. Methods: The subjects were 196 elderly patients with chronic disease staying in the hospital for more than 10 days, Data were collected by the survey of patients with structured questionnaires and medical records review by nurses from July 15 to August 10, 2019. Collected data were analyzed using t-test, ANOVA, Pearson's correlation coefficient and stepwise multiple regression. Results: The present and desired LOS were 37.78±32.66 days and 60.87±45.95 days, respectively. Factors affecting hospital LOS were found to be main disease (genitourinary) (p<.001), assistance in activities of daily living (p<.001), area of hospital (p<.001), payment of medical fees (p=.026), hospital satisfaction (p=.036) and the explanatory power of these variables was 26.4%. The most common health problems that need to be solved after discharge were symptom alleviation and health promotion. These problems can be solved using community-based facility services or visiting medical-welfare services (especially home care nursing). Conclusion: In order to reduce hospital LOS, the following measures are required: personalized self-management education, provision of transportation services for dialysis therapy of inactive patients, linking patients with visiting medical-welfare services including home care nursing and mobile healthcare services, operation of the case management system including the notice of the discharge date at admission, interim check of patient status, and connecting the patient with community resources or transferring the patient to long-term care facilities at discharge.

Purpose: The first-line treatment of temporomandibular joint disorders (TMDs) should include self-management and education. Self-management techniques include moist heat application, stretching, diet control, and mandibular rest position adjustment. Although the effectiveness of video educational resources has been studied in multiple sectors, their application in TMD management has not yet been explored. This study seeks to assess how effective media education was at motivating TMD patients to self-management and improve symptoms. Methods: Data were obtained from the hospital records of TMD patients who visited the Department of Oral Medicine, Yonsei University Dental Hospital, between May 2020 and December 2021. First, without any differences between groups, a significance analysis was conducted between the degree of self-management and symptom improvement over time. At the second visit, one group received media education (n=31) linked to TMD management, while the other received written-oriented education (n=45). At the third visit, the number of precautions taken by the patients was determined and contrasted to that recorded in the previous visit between the groups. Generalized estimated equation multivariate models were applied for statistical analysis. Results: In the media education group, the frequency of stretching and the number of patients on pain-free diets increased substantially. Taking precautions improved daily pain intensity, maximum mouth opening, and pain intensity during the maximum unassisted opening. Conclusions: Media education could be beneficial for TMD patients because it allows them to take self-management precautions. The symptoms of the media education group improved, with no considerable distinction between both groups.

Objectives : Severe mental illness is a major risk factor for suicide. This study aimed to identify characteristics of patients who died by suicide among subjects who had been received service from a community mental health center. Methods : We searched individuals who had committed suicide in Gwangju Bukgu Community Mental Health Center since 2006. Sociodemographic and clinical data were gathered from medical records and their case managers and they were compared with those of general members in the center. Characteristics of schizophrenia patients who died by suicide were particularly summarized. Results : Twelve person committed suicide between 2006 and 2016. The characteristics of those who died by suicide were male (67%), diagnosis of schizophrenia (75%), aged below 50 (83%), unemployed (92%), past history of psychiatric hospitalization (100%), recent admission within 3 months (67%), past history of suicidal attempt (78%), family history of schizophrenia (58%), poor adherence to medication (58%), and use of daily rehabilitation program (42%). Ten out of twelve (83%) showed warning sign for suicide. All identified method of suicide in patients with schizophrenia was jumping from high building. Many patients with schizophrenia, who committed suicide, suffered from comorbid depressive symptoms (67%) and auditory hallucination (78%). Conclusion : Case managers should pay attention to and carefully manage individuals who showed suicidal warning, particularly with risk factors for suicide, such as unemployment, admission state or recent discharge from psychiatric hospital, poor adherence to medication, family history of schizophrenia, and a history of suicidal attempt.
