BackgroundThe evaluation of teens with self-harming thoughts (SHT) is a high-stakes task for physicians in community and emergency department (ED) settings. The lived experience of adolescents with stress and SHT provides an important source of insight for mental health professionals who evaluate and treat teens A snapshot of the lived experience of teens in northwest Louisiana was captured by the Step Forward Teen Advisory Council (TAC) in 2019. The TAC surveyed peers with the goal of identifying common stressors experienced by local teens in order to inform policy and practices in the local school system. The identification of stressors is a critical step in addressing SHT as adolescents who experience life stressors are at increased risk for self-harming thoughts (SHT), a known precursor to self-harm and suicide. Assessing youth for life stressors is a critical element of suicide prevention.MethodsLocal teens queried 5,070 peers attending Caddo Parish schools to better understand the stressors faced by high school students in Northwest Louisiana using a student developed survey. Results were presented to peers at a virtual summit where teens developed action items to reduce stress and presented findings to local leaders. Their efforts ultimately lead to increased supports for students in local schools.ResultsOver half of the teens surveyed reported stressors that negatively impacted their physical or emotional well-being. Students endorsing self-harming thoughts reported an average of 7.82 stressors as compared to 3.47 in peers without SHT. Teens with stressors at both home and school were more likely to experience SHT than teens with stressors in a single location.ConclusionThe Gen Z students who developed the TAC Survey identified stress as a major concern for teens in Northwest Louisiana. The TAC Survey data aligns local experience with established data regarding the association between stress, depression and SHT. Second, the results highlight the importance of diving deep to identify all stressors when assessing the risk of self-harm. Finally, the lived experience of local teens with SHT provides critical information for professionals to better understand risk for SHT and suicide in our region and beyond.

BackgroundSchizophrenia (SC) is considered the most serious of all mental disorders. Some antipsychotics are associated with weight gain and metabolic abnormalities. Whether SC itself causes obesity remains uncertain.MethodsWe collected 185 first-episode drug-naive SC and 59 healthy controls (HCs) from the Third People’s Hospital of Foshan, Guangdong, China, and distinguished their course of disease in order to understand the body mass index (BMI) and body fat metabolism of SC.ResultsWe found that excluding the drug factors, the longer the course of SC, the more obvious the increase of BMI and the higher the proportion of obesity. BMI was positively correlated with age, course of disease, fasting blood glucose (FBG), low-density lipoprotein (LDL), triglyceride (TG), and total cholesterol (TC), and negatively correlated with high-density lipoprotein (HDL). The results of regression analysis were further proof that age (B = 0.094, p &lt; 0.001), duration (B = 0.081, p = 0.002), FBG (B = 0.987, p = 0.004), and TG (B = 0.918, p = 0.002) were the risk factors for the increase of BMI. HDL (B = –2.875, p &lt; 0.001) was the protective factor.ConclusionSC itself can increase BMI and easily lead to obesity. We should pay more attention to the monitoring of blood metabolism indicators, so as to reduce the risk of obesity and improve the quality of life of patients.

Published: June 2022

BackgroundThe COVID-19 pandemic and response have the potential to disrupt access and use of reproductive, maternal, and newborn health (RMNH) services. Numerous initiatives aim to gauge the indirect impact of COVID-19 on RMNH.MethodsWe assessed the impact of COVID-19 on RMNH coverage in the early stages of the pandemic using panel survey data from PMA-Ethiopia. Enrolled pregnant women were surveyed 6-weeks post-birth. We compared the odds of service receipt, coverage of RMNCH service indicators, and health outcomes within the cohort of women who gave birth prior to the pandemic and the COVID-19 affected cohort. We calculated impacts nationally and by urbanicity.ResultsThis dataset shows little disruption of RMNH services in Ethiopia in the initial months of the pandemic. There were no significant reductions in women seeking health services or the content of services they received for either preventative or curative interventions. In rural areas, a greater proportion of women in the COVID-19 affected cohort sought care for peripartum complications, ANC, PNC, and care for sick newborns. Significant reductions in coverage of BCG vaccination and chlorohexidine use in urban areas were observed in the COVID-19 affected cohort. An increased proportion of women in Addis Ababa reported postpartum family planning in the COVID-19 affected cohort. Despite the lack of evidence of reduced health services, the data suggest increased stillbirths in the COVID-19 affected cohort.DiscussionThe government of Ethiopia's response to control the COVID-19 pandemic and ensure continuity of essential health services appears to have successfully averted most negative impacts on maternal and neonatal care. This analysis cannot address the later effects of the pandemic and may not capture more acute or geographically isolated reductions in coverage. Continued efforts are needed to ensure that essential health services are maintained and even strengthened to prevent indirect loss of life.

Published: June 2022

Background and ObjectivesOff-campus online learning methods abruptly increased and gained popularity during the COVID-19 pandemic. Previous studies have highlighted the limitations of online learning mode; however, further studies on the experiences of medical students are needed. This study aimed to investigate the preclinical medical students and faculty members' experiences with online education and learning.Subjects and MethodsIn this cross-sectional study, data were collected using convenience sampling. Two hundred nine students and 13 faculty members who participated in the online courses offered during the spring semester of 2019–2020 completed an online questionnaire. A 30-item questionnaire for the students and a 25-item questionnaire for the faculty were used in this cross-sectional study.ResultsOverall, 30% of the student sample was satisfied; importantly, high-achieving students (GPA &gt; 3.5) were less satisfied (25 vs. 32%; p = 0.006). Satisfaction was also low (35%) for student-faculty interaction opportunities. About half of the student sample agreed that small-group interactive sessions would improve learning (53%). The most favored course format was the blended mode (43%), followed by traditional (40%) and online modes (17%). Six out of 13 (46%) faculty members were satisfied with their online experiences. Most of them found virtual teaching applications convenient (77%). Conversely, few faculty members agreed to interact effectively (54%), while 69% favored a blended format.ConclusionsThe level of satisfaction in fully online courses offered during the COVID-19 pandemic remained low, especially among high-achieving students. Both students and faculty favored the blended format for future purposes. Small group active-learning strategies and web-based interactive tools may facilitate engagement and student-faculty interactions.

Published: June 2022

Objective:This study aimed to distinguish the risk variables of nonalcoholic fatty liver disease (NAFLD) and to construct a prediction model of NAFLD in visceral fat obesity in Japanese adults.MethodsThis study is a historical cohort study that included 1,516 individuals with visceral obesity. All individuals were randomly divided into training group and validation group at 70% (n = 1,061) and 30% (n = 455), respectively. The LASSO method and multivariate regression analysis were performed for selecting risk factors in the training group. Then, overlapping features were selected to screen the effective and suitable risk variables for NAFLD with visceral fatty obesity, and a nomogram incorporating the selected risk factors in the training group was constructed. Then, we used the C-index, calibration plot, decision curve analysis, and cumulative hazard analysis to test the discrimination, calibration, and clinical meaning of the nomogram. At last, internal validation was used in the validation group.ResultsWe contract a nomogram and validated it using easily available and cost-effective parameters to predict the incidence of NAFLD in participants with visceral fatty obesity, including ALT, HbA1c, body weight, FPG, and TG. In training cohort, the area under the ROC was 0.863, with 95% CI: 0.84–0.885. In validation cohort, C-index was 0.887, with 95%CI: 0.857–0.888. The decision curve analysis showed that the model's prediction is more effective. Decision curve analysis of the training cohort and validation cohort showed that the predictive model was more effective in predicting the risk of NAFLD in Japanese patients with visceral fatty obesity. To help researchers and clinicians better use the nomogram, our online version can be accessed at https://xy2yyjzyxk.shinyapps.io/NAFLD/.ConclusionsMost patients with visceral fatty obesity have a risk of NALFD, but some will not develop into it. The presented nomogram can accurately identify these patients at high risk.

We took a survey of boundary layer (or low-latitude boundary layer) crossings by the Magnetospheric Multiscale (MMS) mission. Out of 250 total crossings, about half showed enhancements of high-energy (>30 keV) electrons in the FEEPS sensor and a little less than half of those energetic electron events had whistler-mode waves present. Energetic electron enhancements were more likely to be present at magnetic local times closer to noon and at distances of less than about 20 Earth radii, but there was seemingly no correlation with magnetic latitude. For almost all of these events, the pitch angles of the FEEPS electrons were peaked at 90° or isotropic, not field-aligned. Most of the events for which we had data to make a determination showed either direct or indirect evidence of reconnection. Overall, energetic electron enhancements are a fairly common occurrence and there appears to be some connection between whistler waves, energetic electron enhancements, and reconnection, whether it is a direct link or some other process affecting all of them.

Published: June 2022

BackgroundTo investigate the efficacy and safety of preoperative intravenous tranexamic acid (TXA) combined with intraoperative immersion in reducing perioperative blood loss in one-stage posterior thoracolumbar tuberculosis.MethodsAll patients were divided into four groups: Group A received an intravenous drip of TXA before surgery, group B received multiple local immersions during the operation, group C received an intravenous drip combined with multiple local immersions, and the control group (group CG) were not treated with TXA during the same period. The total blood loss (TBL), intraoperative blood loss (IBL), hidden blood loss (HBL), postoperative drainage volume, maximum hemoglobin drop value (max Hb drop), liver and kidney function, coagulation indexes, blood transfusion rate, hospital stay and incidence of complications were compared among the four groups.ResultsTBL, IBL, HBL, max Hb drop, POD1 drainage, and POD2 drainage in group A, group B, and group C were significantly lower than those in group CG. TBL, IBL, HBL and max Hb drop were group C &lt; group A &lt; group B &lt; group CG. The drainage volume of group C was significantly lower than that of the other groups. There was no significant difference in blood coagulation index (PT, D-D) or liver and kidney function (ALT, Cr) among the four groups. There was no difference in postoperative hospital stay between group A and group B, but it was significantly lower in group C than in the other three groups. All patients achieved satisfactory bone graft fusion at the last follow-up.ConclusionPreoperative intravenous drip of TXA combined with intraoperative multiple immersion can effectively reduce perioperative blood loss while not increasing the risk of thrombosis without affecting liver and kidney function, coagulation function or tuberculosis prognosis.

Necrotic enteritis (NE) is a multifactorial and important enteric infectious disease etiologically caused by pathogenic C. perfringens infection, accounting for the estimated loss of around USD 6 billion in the global poultry industry. The increasing incidence of NE was found to be associated with the voluntary reduction or withdrawal of antibiotic growth promoters from animal feed during recent years. Therefore, the development of effective vaccines specific to NE assumes a priority for the poultry industry. This study aimed to identify the potential C. perfringens proteins as vaccine targets for NE. Three recombinant C. perfringens proteins targeting five antigens were prepared: two chimeric proteins (alpha-toxin and NetB, fructose-1,6-bisphosphate aldolase (FBA) and a zinc metalloprotease (Zm)), and one single collagen adhesion protein (Cna). Their protection efficacies were evaluated with a potent challenge model of Eimeria maxima/C. perfringens dual infections using a netB+tpeL+ C. perfringens strain. Young chicks were immunized twice subcutaneously with adjuvanted C. perfringens proteins on Days 4 and 15. At six days after the second immunization, the chickens immunized with Cna, FBA, and Zm antigens, and alpha-toxin had much higher serum antibody titers than unvaccinated controls prior to the challenge. Following the challenge, the pooled antigen-immunized group demonstrated no mortality and the least lesion scores against virulent challenge. The results indicate that the immunization with multicomponent antigens, including C. perfringens housekeeping protein Cna, may confer partial protection.

Relevance. Branchio-oto-renal syndrome (also known as Melnick-Fraser syndrome) is a rare syndrome characterized by hearing loss, renal malformations and branchial cyst (fistula) association. The article describes a clinical case of a boy with an atypical clinical picture of branchio-oto-renal syndrome.Material and methods. The patient was admitted to our clinic with acute inflammation, complaints of hearing loss and a fistulous tract in the right retromandibular region.Results. After the acute inflammation resolution and necessary investigations, the patient underwent a fistulectomy for diagnosis verification. We analyzed the patient routing from the first presentation to the patient's GP to the final diagnosis in our clinic. Based on this clinical case result analysis, we offered optimal diagnosis and treatment tactics for patients with Melnick-Fraser syndrome.Conclusion. Correct branchio-oto-renal syndrome diagnosis requires careful history taking, clinical examination and multidisciplinary team involvement. This approach will allow the patient to receive a full range of treatments with quality-of-life preservation.

Mundos em contraponto: exílio e memória em Edward Said
Authors: El Far Alessandra 
Published: June 2022

Este artigo procura explorar o diálogo entre dois textos de Edward Said: o artigo Reflexões sobre o exílio, publicado em 1984 na revista inglesa Granta, e suas memórias, escritas entre 1994 e 1999, que receberam por título a expressão em inglês Out of place. Se, em suas memórias, Said repetidas vezes faz referência sobre o sentimento de deslocamento que o acompanhou por toda a vida, em razão de ter nascido em Jerusalém e crescido no Egito, onde também recebeu educação ocidental; em Reflexões sobre o exílio, Said aponta na experiência do exílio a possibilidade de sobrepor mundos, como alude o conceito contrapontística, na teoria musical, conferindo ao sujeito deslocado, apartado de sua terra natal, a justaposição de diferentes perspectivas culturais, algo capaz de reduzir essencialismos e ampliar a “originalidade da visão”. Este artigo procurará analisar igualmente as memórias de Edward Said como um lugar de fala e, nesse sentido, como uma narrativa que ao lançar luz às experiências coloniais vividas por ele desde a infância acaba por estabelecer fortes vínculos com sua própria obra intelectual.
Аналіз кластерної структури Інтернет-мереж на основі випадкових матриць
Authors: Кириченко Оксана Леонідівна , Малик Ігор Володимирович , Остапов Cергій Едуардович 
Published: June 2022

Основна увага надається оцінці оптимальної кількості кластерів для системи, що задається матрицею суміжності A з N вузлами при N→∞ . Розглянуто асимптотичний розподіл власних значень стохастичної випадкової матриці без умов незалежності елементів, спектр якої можна розкласти на регулярну частину та викиди. На основі припущень про однотипність зв’язків у кластері зроблено висновок про оптимальну кількість кластерів для різних прикладних задач. Проведено моделювання мережі зв’язків, що розподілені за законом Пуассона, та знайдено оптимальну кількість кластерів. Результати моделювання вказують на високу точність визначення оптимальної кількості кластерів. У основній теоремі важливим є припущення про існування моменту вище другого для кожного елементу матриці A. Проте, з урахуванням нормалізації, цю умову можна послабити до існування математичного сподівання матриці. Дане послаблення умов збіжності дає можливість використання доведеного твердження на ширший клас прикладних задач, де наявність скінченної дисперсії не вимагається. Зазначимо, що викиди є дійсними власними значеннями для нормалізованої матриці, що дозволяє швидко локалізувати викиди зі складністю O(N), де N — кількість вузлів системи. Отже, вдалося послабити два важливі припущення щодо розподілу елементів випадкової матриці, а саме припущення про рівність нулю математичних сподівань елементів матриці та про незалежність елементів матриці. Крім того, незалежність елементів можна замінити слабкою незалежністю, яка зберігає збіжність до середнього значення в законі великих чисел.
