Although re-expansion pulmonary edema (RPE) is rare (incidence rate <1%), it is associated with a mortality rate of >20%; therefore, early diagnosis and treatment are important. We report a case of RPE following chest tube insertion in a patient with spontaneous pneumothorax. We have specifically focused on the mechanism underlying RPE and the possible etiology. An 82-year-old man with a history of chronic anemia, chronic obstructive pulmonary disease, diabetes mellitus, and hypertension was referred to the emergency department for management of recurrent right-sided pneumothorax. We performed emergency closed thoracostomy for suspected tension pneumothorax, which led to stabilization of the patient's vital signs; however, he coughed up frothy pink sputum accompanied by severe right-sided chest pain 30 min postoperatively. The patient showed new-onset right pulmonary consolidation on chest radiography, as well as desaturation, tachycardia, and tachypnea and was diagnosed with RPE. He was transferred to the intensive care unit for mechanical ventilation and supportive treatment using diuretics, ionotropic agents, and prophylactic antibiotics. RPE gradually resolved, and the patient was extubated 3 days after admission. He has not experienced recurrent pneumothorax or pulmonary disease for 4 months. We emphasize the importance of RPE prevention and that aggressive ventilator care and supportive treatment can effectively treat RPE following an accurate understanding of the underlying pathogenetic mechanisms and risk factors.

A mushroom as a functional food material is being increasingly used in these days. It has been that about 1,500 species of mushrooms grow naturally in Asia. Among them about 700 species are edible, but about 30-50 species are poisonous. Even a poisonous mushroom is a very interesting subject for the dietary life research from biochemical viewpoint due to the fact that any mushroom can be the physiological active material. Not a few identified poisonous materials are being used as research reagents thus far. It is suggested that more useful materials could be obtained by progresses in future researches. The identification of the poisonous ingredient can open up a route for mushroom intoxication cure. It is known that cell destruction and troubles on skin, liver, and kidney troubles can be occurred from mushroom intoxication. Recently the author reported as a collection of treatises regarding anti-tumor substances of mushroom (2005), antibiotic substances of mushroom (2006), living-body functional and control substance (2007), and medicinal mushroom commonly used in Korean herbal medicines (2008). In this sequel, published research data on protoplasm, nerve, stomach and intestines, malodor, and acute pain poison of mushroom are collected and reported.

In this paper, we propose a system that accurately and efficiently determines forward head posture based on network learning by analyzing the user's skeletal posture. Forward head posture syndrome is a condition in which the forward head posture is changed by keeping the neck in a bent forward position for a long time, causing pain in the back, shoulders, and lower back, and it is known that daily posture habits are more effective than surgery or drug treatment. Existing methods use convolutional neural networks using webcams, and these approaches are affected by the brightness, lighting, skin color, etc. of the image, so there is a problem that they are only performed for a specific person. To alleviate this problem, this paper extracts the skeleton from the image and learns the data corresponding to the side rather than the frontal view to find the forward head posture more efficiently and accurately than the previous method. The results show that the accuracy is improved in various experimental scenes compared to the previous method.

The β subunits of high voltage-gated calcium channels (HGCCs) are essential for optimal channel functions such as channel gating, activation-inactivation kinetics, and trafficking to the membrane. In this study, we report for the first time the potent blood pressure-reducing effects of peptide fragments derived from the β subunits in anesthetized and non-anesthetized rats. Intravenous administration of 16-mer peptide fragments derived from the interacting regions of the β1 [cacb1(344-359)], β2 [cacb2(392-407)], β3 [cacb3(292-307)], and β4 [cacb4(333-348)] subunits with the main α-subunit of HGCC decreased arterial blood pressure in a dose-dependent manner for 5-8 min in anesthetized rats. In contrast, the peptides had no effect on the peak amplitudes of voltage-activated Ca²⁺ current upon their intracellular application into the acutely isolated trigeminal ganglion neurons. Further, a single mutated peptide of cacb1(344-359)-cacb1(344-359)_K357R-showed consistent and potent effects and was crippled by a two-amino acid-truncation at the N-terminal or C-terminal end. By conjugating palmitic acid with the second amino acid (lysine) of cacb1(344-359)_K357R (named K2-palm), we extended the blood pressure reduction to several hours without losing potency. This prolonged effect on the arterial blood pressure was also observed in non-anesthetized rats. On the other hand, the intrathecal administration of acetylated and amidated cacb1(344-359)_K357R peptide did not change acute nociceptive responses induced by the intradermal formalin injection in the plantar surface of rat hindpaw. Overall, these findings will be useful for developing antihypertensives.

Rape myth acceptance may influence victims are treated and perpetrator blamed and sentenced. And this relationship could be moderated by victim's deviant behavior before rape such as teenage running away from home or drinking alcohol. The present study examined the relationship among rape myth, deviant behavior, blaming victim, pain of victim, responsibility and blame for perpetrator and punishment for the perpetrator. Findings suggest that participants with high rape myth acceptance compared to participants with low rape myth acceptance blamed victim more and blamed and thought responsible the perpetrator less. And this relationship was only significant when the victim had deviant behavior before rape happened. This result shows that specific information(deviant behaior) about victim could trigger rape myth to blame victim and judge the perpetrator leniently. The suggestions for future research and limitations were discussed.

Purpose: This study aimed to comprehensively analyze the recent revision of the Outcome and Assessment Information Set (OASIS)-D to version E in the United States to identify the most recent trends in home health care and provide suggestions for implementing home health care in Korea. Methods: This study is a comprehensive literature review. We compared all items in OASIS-D and OASIS-E and identified the most significant changes. Additionally, we have discussed the context in depth. Results: The addition of items related to health literacy and medication reconciliation, strengthening assessment in the cognitive and mood domains, and improving items related to pain assessment were identified. These major revisions resulted from a greater emphasis in the healthcare field on social determinants of health. Additionally, the COVID-19 outbreak highlighted the importance of monitoring and managing the symptoms of home care patients in the community. Conclusion: The key items of the OASIS amendment and their background analysis proposed in this study could serve as a cornerstone for the revision of home health care assessment tools or the development of systematic common assessment tools in Korea.

Purpose: We evaluated the status of patients enrolled in South Korea's pediatric palliative care pilot project based on the experience of a single center. This study examined factors related to end-of-life services and differences in medical costs. Methods: The medical records of 120 patients referred by a pediatric palliative care team were analyzed retrospectively. Data from July 1 to February 28, 2022 were collected and analyzed using the chi-square test and the Mann-Whitney U test. Results: Volunteer programs and psychological support (100%), family support and education (99.2%), and financial support through institutional linkage (62.5%) were provided to the participants. In the deceased group, there were no significant differences in general characteristics, which included age, gender, primary disease, religion, duration of hospitalization in an intensive care unit (ICU) and non-intensive care unit (non-ICU). However, the ICU group had fewer opportunities to access individual pain and physical symptom management than the non-ICU group and there were limitations in linking with external resources. Medical expenses were significantly different for the ICU group, with a 3-times higher average cost than the non-ICU group. Conclusion: Although an individualized approach is needed for each patient in pediatric palliative care, psychosocial care is essential. In addition, if early intervention for end-of-life pediatric patients is available from a palliative care team, the cost burden of medical care for patients and their families should be minimal.

Objectives: Systemic lupus erythematosus (SLE) or lupus patients usually experience various physical and psychological challenges. Since the coronavirus disease 2019 pandemic, these challenges have become even harsher. Using the participatory action research approach, this study evaluated how an e-wellness program (eWP) impacted SLE-related knowledge and health behaviors, mental health, and quality of life among lupus patients in Thailand. Methods: A 1-group, pretest-posttest design study was conducted among a purposive sample of lupus patients who were members of Thai SLE Foundation. The 2 main intervention components were: (1) online social support, and (2) lifestyle and stress management workshops. Sixty-eight participants completed all the study requirements, including the Physical and Psychosocial Health Assessment questionnaire. Results: After being in the eWP for 3 months, participants' mean score for SLE-related knowledge increased significantly (t=5.3, p<0.001). The increase in sleep hours was statistically significant (Z=-3.1, p<0.01), with the percentage of participants who slept less than 7 hours decreasing from 52.9% to 29.0%. The percentage of participants reporting sun exposure decreased from 17.7% to 8.8%. The participants also reported significantly lower stress (t(66)=-4.4, p<0.001) and anxiety (t(67)=-2.9, p=0.005). The post-eWP quality of life scores for the pain, planning, intimate relationship, burden to others, emotional health, and fatigue domains also improved significantly (p<0.05). Conclusions: The overall outcomes showed promising results of improved self-care knowledge, health behaviors, mental health status, and quality of life. It is recommended that the SLE Foundation continues to use the eWP model to help the lupus patient community.

A decrease in the paraspinal muscle cross-sectional area (CSA) and functional cross-sectional area (FCSA) are associated with low back pain and disc herniation in humans. This study examined whether chronicity or lateralization of disc herniation affects the CSA and FCSA of the paraspinal muscles. The CSA and FCSA of the paraspinal muscles between the 12th and 13th thoracic vertebrae were measured in 31 dogs with intervertebral disc herniation (IVDH). The muscle CSA and FCSA were evaluated by dividing the values of the body weight, spinal disc CSA, and spinal canal CSA to offset the differences in body type between subjects. In the chronic IVDH group, the ratio of the paraspinal muscle CSA divided by the body weight was significantly lower, and fat infiltration in the paraspinal muscle was significantly higher than in the acute group. The lateralization of the disc herniation was significantly related to the changes in the paraspinal muscle CSA. In the right-sided disc herniation group, right epaxial muscle CSA was significantly reduced compared to the left-sided disc herniation group. The change in the paraspinal muscle might be a helpful indicator to localize less obvious disc pathologies and target the search for the pathology responsible for disc-related symptoms in dogs.

Two-port laparoscopic ovariectomy (Lap-OVE) has been performed in small dogs, using 3-mm and 5-mm portal sites, and is associated with reduced surgical stress and postoperative pain. However, extension of the incision is often needed to extract the ovaries. In this study, we aimed to minimize invasiveness by using smaller-sized cannulas as well as a novel technique for ovary extraction. Lap-OVE was performed on six, healthy female dogs (range, 3 to 7.2 kg) using two 3-mm midline portals. The middle finger of a size M nitrile glove was cut at its base and sterilized preoperatively. The ovary was suspended at the body wall using a 1-0 blue nylon needle, and the ovarian pedicle and ligaments were transected using a 3-mm bipolar forceps. To facilitate the glove passing through the 3.9-mm port, it was turned inside out to expose the smooth inner surface, before being inserted into the abdominal cavity with an applicator. Both ovaries were placed inside, and the mouth of the glove was exteriorized through the port with a laparoscopic grasping forceps. The ovaries were morcellated inside the glove, using Adison-Brown tissue forceps and iris scissors, which enabled safe extraction without incision enlargement. Median incision lengths were 4.3 mm (3.5-mm cranial cannula) and 4.8 mm (3.9-mm caudal cannula). An advantage of this procedure was that there was no need for skin sutures. In conclusion, using our novel technique, sutureless Lap-OVE was possible in small dogs using two 3-mm portal sites without additional incision.
