The prevalence of disordered eating in outpatient general psychiatry settings in publicly insured populations: a case series.

There is a dearth of research assessing the prevalence of eating disorders in publicly insured populations. While evidence shows that eating disorders affect people of all racial, ethnic, and socioeconomic backgrounds, research has neglected to focus on the rate at which they occur among those who have public health insurance. The present study indexes the prevalence of clinically significant disordered eating in a case series of 165 adults in a publicly insured sample at an outpatient general psychiatry clinic in Los Angeles, California. Results illustrate that 46 (27.8%) participants screened positive for clinically significant disordered eating with no significant differences relating to age or gender in those who screened positive versus those who did not (p > .05). This markedly elevated frequency of disordered eating presentations underscores the need for improved clinician training and education around disordered eating and eating disorder assessment as a whole. In addition, there is a critical need to study publicly insured populations so as to mitigate stereotypes about who has eating disorders and improve the likelihood of diagnosis and care.

Updates in the treatment of Eating Disorders in 2022: a year in review in Eating Disorders: The Journal of Treatment & Prevention.

A broad array of important and diverse studies surrounding the treatment of eating disorders were published in Eating Disorders: The Journal of Treatment & Prevention in 2022. Novel interventions such as neurosurgical and neuromodulatory treatments were discussed, as evidence continues to mount around their potential utility in treating eating disorders, in particular namely anorexia nervosa. Important pragmatic and theoretical developments around feeding and refeeding approaches emerged, and are also discussed. In this review, we carefully review evidence alluding to the potential efficacy of exercise in partially ameliorating binge eating disorder symptomatology, while examining broader evidence underscoring the importance of therapeutically ameliorating compulsive exercise in anorexia nervosa and bulimia nervosa. In addition, we overview evidence relating to the risk and sequelae associated with premature discharge from intensive eating disorder treatment, as well as the efficacy of CBT versus group therapy-based maintenance treatments. Finally, important developments around the use of open versus blind weighing in treatment are assessed. Overall, the articles published in Eating Disorders: The Journal of Treatment & Prevention in 2022 evidence the promise of treatment advances in the field and requires further work to address the development of efficacious treatments to achieve greater outcomes for those with eating disorders.

Atypical maculopapular cutaneous mastocytosis showing a nevus spilus-like lesion.

A 13-year-old Korean girl presented with a 7-year history of a pruritic, light-brown patch containing multiple 0.2- to 0.5-cm brownish-to-reddish maculopapules on the left anterior chest. When her skin was rubbed, the lesion became itchy and red. Histopathologic evaluation demonstrated marked dense dermal infiltration of mast cells. We report a rare case of atypical maculopapular cutaneous mastocytosis with clinical features similar to those of nevus spilus.

The Effects of Equine-Assisted Learning on Adolescents with Internet Gaming Disorder.

During the COVID-19 pandemic, internet gaming became more popular as a way to cope with stress, but excessive gaming can lead to mental health issues like internet gaming disorder (IGD). IGD has serious consequences, especially among children and young adults, and the gaming industry's profits continue to grow. This study aims to understand the mental and behavioral health of adolescents with IGD participating in an equine-assisted learning (EAL) program and assess the changes in their addiction tendencies and emotional and behavioral problems. The results showed that the participants' tendency towards internet gaming addiction and emotional and behavioral problems decreased immediately after the EAL program, but they rose again a month later. This suggests the importance of ongoing program involvement. As COVID-19 restrictions ease worldwide, this study highlights the increasing risk of IGD. It suggests that EAL could be a valuable approach to treating behavioral addictions, including gaming addiction. While prior research has shown the effectiveness of EAL in treating substance addiction, more research is needed to explore its potential in treating various types of addictions, such as gambling or gaming addictions.

Hf0.4Zr0.6O2 Thickness-Dependent Transfer Characteristics of InxZn1-xOy Channel Ferroelectric FETs.

We investigate how the threshold voltage (VT) is adjusted to create a memory window (MW) in ferroelectric field-effect transistors (FeFETs) composed of ferroelectric Hf0.4Zr0.6O2 and InZnO (In2O3:ZnO = 9:1 wt %). Temperature-dependent polarization measurements reveal a dipole switching in Hf0.4Zr0.6O2. The properties of the n-type InZnO channel are examined by fabricating an oxide transistor with an HfO2 gate dielectric. Upon replacement of HfO2 with Hf0.4Zr0.6O2 in the oxide transistor, a counterclockwise MW is observed. Specifically, as the Hf0.4Zr0.6O2 thickness increases from 16 to 24 nm, the VT of the FeFET after a + gate voltage (VG) sweep remains nearly constant, while the VT after a -VG sweep shifts significantly from -0.9 to 0.5 V. The enlarged MW of approximately 2 V, which is proportional to the Hf0.4Zr0.6O2 thickness in the FeFET, can be explained by considering the balance between VG controllability across the gate stack and the ferroelectric switching of Hf0.4Zr0.6O2.

The Effect of Equine Assisted Learning on Improving Stress, Health, and Coping among Quarantine Control Workers in South Korea.

Foot-and-Mouth Disease (FMD) and Avian Influenza (AI) frequently occur in South Korea, resulting in high levels of occupational stress among quarantine workers forced to partake in massive livestock killings. This study explored the usefulness of Equine Assisted Learning (EAL) in improving these workers' psychological and emotional functioning. A total of 51 FMD/AI control workers participated in 16 sessions of an EAL program facilitated by therapeutic riding professionals and trained horses. Results showed significant changes in their stress level, coping style, and overall quality of life-related to health, most notably increased vitality, enhanced emotional and social functioning, greater problem-solving, and less social avoidance after EAL participation. The usefulness of equine-assisted activities and the association between more significant stress coping ability and improved functioning in various areas of life are consistent with previous research findings. Implications for EAL application are discussed.

Protocatechuic acid impacts rotator cuff healing and reduces fatty degeneration in a chronic rotator cuff tear model in rats.

BACKGROUND: The purpose of this study was to verify the effect of protocatechuic acid (PCA) on tendon healing and fatty degeneration in a chronic rotator cuff model. METHODS: Twenty-eight Sprague-Dawley male rats were randomly allocated into two groups: Saline+repair (SR) and PCA+repair (PR). The right shoulder was used for experimental interventions, and the left served as a control. PCA (30 mg/kg/day) was administered intraperitoneally at the site of infraspinatus tendon detachment in rats in the PR group, and the same volume of saline was administered to the same site in the SR group. The torn tendon was repaired 4 weeks after infraspinatus detachment. Four weeks after repair, hematoxylin and eosin (H&E), S100, and CD68 stains were performed to evaluate the degree of fatty degeneration and H&E and Masson trichrome stains were performed to assess tendon healing. Superoxide dismutase (SOD) was measured to test the efficacy of PCA as an antioxidant. RESULTS: Results from histological evaluation indicated that SOD and CD68 levels at the musculotendinous region and collagen fiber parallel to the orientation at the tendon-to-bone junction were not significantly different between the SR and PR groups. The mean load-to-failure of the PR group (20.32±9.37 N) was higher than that of the SR group (16.44±6.90 N), although this difference was not statistically significant (p=0.395). The SOD activity in the operative side infraspinatus muscle of the PR group was higher than that of the SR group, but the difference was not statistically significant (p=0.053). CONCLUSIONS: The use of PCA could improve tendon healing and decrease fatty degeneration after rotator cuff repair.

Internal sinus manipulation (ISM) procedure: a technical report.

BACKGROUND: The sinus augmentation procedure has facilitated dental implant treatment in the posterior maxilla where there is insufficient bone for implant placement. A modified Caldwell-Luc, lateral window technique can be applied in most cases needing sinus augmentation in order to create a larger bone volume. However, treatment morbidity can be a concern, especially in the form of postoperative swelling due to surgical trauma. Vertical augmentation using osteotomes has also been selected as a choice of treatment due to less invasive surgery and less postoperative trauma. Although the osteotome technique enables the surgeon to raise the sinus membrane internally through an implant osteotomy site, the quantity and predictability of bone augmentation can be limiting due to the elasticity of the Schneiderian sinus membrane, difficulty of the membrane to separate from the floor as well as the inability to have direct tactile access to "peel" the membrane off of the floor. PURPOSE: The objective of this report is to present a new, minimally invasive sinus augmentation technique, called the Internal Sinus Manipulation (ISM) procedure, which has been developed to facilitate sinus floor augmentation while reducing treatment morbidity and yet have direct tactile access to raise the membrane off of the sinus floor. SURGICAL TECHNIQUE: Access to the Schneiderian sinus membrane is achieved without perforation of the membrane through a conventional osteotomy drilling procedure alone or combined with osteotome technique, followed by reflection of the membrane utilizing special ISM instrumentation and bone graft procedure laterally and vertically through the osteotomy site. A planned implant is then placed. CONCLUSION: The Internal Sinus Manipulation procedure can be used as an alternative treatment modality for sinus augmentation as compared to the external lateral window technique while reducing postoperative morbidity for the patients who need implant treatment in posterior maxillary areas.

Aronia melanocarpa Extract Ameliorates Hepatic Lipid Metabolism through PPARγ2 Downregulation.

Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic syndrome. Studies have demonstrated that anthocyanin-rich foods may improve hyperlipidemia and ameliorate hepatic steatosis. Here, effects of Aronia melanocarpa (AM), known to be rich of anthocyanins, on hepatic lipid metabolism and adipogenic genes were determined. AM was treated to C57BL/6N mice fed with high fat diet (HFD) or to FL83B cells treated with free fatty acid (FFA). Changes in levels of lipids, enzymes and hormones were observed, and expressions of adipogenic genes involved in hepatic lipid metabolism were detected by PCR, Western blotting and luciferase assay. In mice, AM significantly reduced the body and liver weight, lipid accumulation in the liver, and levels of biochemical markers such as fatty acid synthase, hepatic triglyceride and leptin. Serum transaminases, indicators for hepatocyte injury, were also suppressed, while superoxide dismutase activity and liver antioxidant capacity were significantly increased. In FL83B cells, AM significantly reduced FFA-induced lipid droplet accumulation. Protein synthesis of an adipogenic transcription factor, peroxisome proliferator-activated receptor γ2 (PPARγ2) was inhibited in vivo. Furthermore, transcriptional activity of PPARγ2 was down-regulated in vitro, and mRNA expression of PPARγ2 and its downstream target genes, adipocyte protein 2 and lipoprotein lipase were down-regulated by AM both in vitro and in vivo. These results show beneficial effects of AM against hepatic lipid accumulation through the inhibition of PPARγ2 expression along with improvements in body weight, liver functions, lipid profiles and antioxidant capacity suggesting the potential therapeutic efficacy of AM on NAFLD.

Gamma-aminobutyric acid secreted from islet beta-cells modulates exocrine secretion in rat pancreas.

AIM: To investigate the role of endogenous gamma-amino-butyric acid (GABA) in pancreatic exocrine secretion. METHODS: The isolated, vascularly perfused rat pancreas was employed in this study to eliminate the possible influences of extrinsic nerves and hormones. Cholecystokinin (CCK; 10 pmol/L) was intra-arterially given to stimulate exocrine secretion of the pancreas. RESULTS: Glutamine, a major precursor of GABA, which was given intra-arterially at concentrations of 1, 4 and 10 mmol/L, dose-dependently elevated the CCK-stimulated secretions of fluid and amylase in the normal pancreas. Bicuculline (10 micromol/L), a GABA(A) receptor antagonist, blocked the enhancing effect of glutamine (4 mmol/L) on the CCK-stimulated exocrine secretions. Glutamine, at concentrations of 1, 4 and 10 mmol/L, dose-dependently increased the GABA concentration in portal effluent of the normal pancreas. The effects of glutamine on the CCK-stimulated exocrine secretion as well as the GABA secretion were markedly reduced in the streptozotocin-treated pancreas. CONCLUSION: GABA could be secreted from beta-cells into the islet-acinar portal system after administration of glutainine, and could enhance the CCK-stimulated exocrine secretion through GABA(A) receptors. Thus, GABA in islet beta-cells is a hormone modulating pancreatic exocrine secretion.
