Abstract
Background
Recently, it has become possible to analyze implant placement position using the digital matching data of optical impression data of the oral cavity or plaster models with cone beam computed tomography (CBCT) data, and create a highly accurate surgical guide. It has been reported that CBCT measurements were smaller than the actual values, termed shrinkage. Matching of digital data is reliable when the plaster model or intraoral impression values show shrinkage at the same rate as the CBCT data. However, if the shrinkage rate is significantly different, the obtained digital data become unreliable. To clarify digital matching reliability, we examined dimensional reproducibility and shrinkage in measurements obtained with a model scanner, intra-oral scanner (iOS), and CBCT.

Materials and methods
Three implants that were arranged in a triangle were fixed in an acrylic plate. The distance between each implants were measured using model scanner, iOS, and CBCT. The actual size measured by electronic caliper was regarded as control.

Results
All values measured with CBCT were significantly smaller than that of model scanner, iOS, and control (p<0.001). The model scanner shrinkage was 0.37-0.39%, iOS shrinkage was 0.9-1.4%, and CBCT shrinkage was 1.8-6.9%. There were statistically significant differences among the shrinkage with iOS, CBCT, and model scanner (p<0.001).

Conclusion
Our findings showed that all measurements obtained with those modalities showed shrinkage as compared to the actual values. In addition, CBCT shrinkage was largest among three different measuring methods. They indicated that data matching between CBCT and scanner measurements requires attention in regard to the reliability of values obtained with those devices.

Abstract
Background
Acute mediastinitis is a rare disease that rapidly progresses with a high mortality rate. Its most common cause is direct injury of the mediastinum, including iatrogenic causes such as cardiac surgery or upper endoscopy. Enzymatic mediastinitis is a rare complication of a pancreatic fistula caused by the inflammatory digestion of the parietal peritoneum spreading to the mediastinum. Here, we present two cases of enzymatic mediastinitis caused by total gastrectomy with splenectomy. One of them was successfully treated and cured after early diagnosis and transabdominal drainage.

Case presentation
Case 1 was that of a 60-year-old man (body mass index [BMI] 27) with a medical history of diabetes and hypertension who was diagnosed with advanced gastric cancer in the upper body of the stomach. A total gastrectomy with splenectomy was performed. The patient experienced acute respiratory failure 24 h after surgery. Pulmonary embolism was suspected, so a computed tomography (CT) scan was performed; however, no relevant causes were found. Although he was immediately intubated and treated with catecholamine, he died in the intensive care unit (ICU) 40 h after surgery. Post-mortem findings revealed retroperitonitis caused by a pancreatic fistula spreading towards the mediastinum, causing severe mediastinitis; a review of the CT scan revealed pneumomediastinum. We concluded that the cause of death was enzymatic mediastinitis due to post-gastrectomy pancreatic fistula. Case 2 involved a 61-year-old man (BMI 25) with a medical history of appendicitis who was diagnosed with advanced gastric cancer at the gastric angle between the lesser curvature and the pylorus, spreading to the upper body of the stomach. A total gastrectomy with splenectomy was also performed. The patient had a high fever 3 days after the surgery, and a CT scan revealed pneumomediastinum, indicating mediastinitis. As the inflammation was below the bronchial bifurcation, we chose a transabdominal approach for drainage. The patient was successfully treated and discharged.

Conclusion
Acute mediastinitis caused by gastrectomy is rare. The acknowledgment of abdominal surgery as a cause of mediastinitis is important. In treating mediastinitis caused by abdominal surgery, transabdominal drainage may be a minimally invasive yet effective method if the inflammation is mainly located below the bifurcation of the trachea.

Published: June 2021

Abstract
Background
Engaging parents in child health research can facilitate choosing relevant research questions, recruiting participants who reflect the diversity of large communities, and disseminating study results to communities in accessible ways.

Main body
Primary care well-child visit systems present a foundation for trusting relationships between families and clinicians, lending itself well to a system where health research is embedded into the delivery of health care. We provide an example of a practice-based research network called TARGet Kids!, which is a longitudinal cohort study of children from birth to adolescence. Researchers and clinicians have partnered with parents of children participating in TARGet Kids! to ensure child health research is centred on family values and preferences. A Parent And Clinician Team (PACT) was formed to set research priorities, co-design research protocols, troubleshoot issues, and communicate research to knowledge users.

Conclusion
This partnership will facilitate child health research which is feasible, relevant and inclusive for improving children’s health care and public health policy.
Chatbot to improve learning punctuation in Spanish and to enhance open and flexible learning environments

Published: June 2021

AbstractThe objective of this article is to analyze the didactic functionality of a chatbot to improve the results of the students of the National University of Distance Education (UNED / Spain) in accessing the university in the subject of Spanish Language. For this, a quasi-experimental experiment was designed, and a quantitative methodology was used through pretest and posttest in a control and experimental group in which the effectiveness of two teaching models was compared, one more traditional based on exercises written on paper and another based on interaction with a chatbot. Subsequently, the perception of the experimental group in an academic forum about the educational use of the chatbot was analyzed through text mining with tests of Latent Dirichlet Allocation (LDA), pairwise distance matrix and bigrams. The quantitative results showed that the students in the experimental group substantially improved the results compared to the students with a more traditional methodology (experimental group / mean: 32.1346 / control group / mean: 28.4706). Punctuation correctness has been improved mainly in the usage of comma, colon and periods in different syntactic patterns. Furthermore, the perception of the students in the experimental group showed that they positively value chatbots in their teaching–learning process in three dimensions: greater “support” and companionship in the learning process, as they perceive greater interactivity due to their conversational nature; greater “feedback” and interaction compared to the more traditional methodology and, lastly, they especially value the ease of use and the possibility of interacting and learning anywhere and anytime.

Published: June 2021

Abstract
Background
This study aimed at assessing the effect of different kinematics as well as different instrument designs on efficiency of cutting of two heat-treated nickel–titanium systems. Forty resin canals with 30°-angle of curvature and a length of 16 mm were utilized in this research. They were divided into four groups depending on the instrument and the operating kinematic, group I; Azure rotary system in rotation motion, group II; Azure rotary system in Reciprocation motion, group III; Fanta AF One rotary system in rotation motion and group IV; Fanta AF One rotary system in reciprocation motion. Blocks were labeled and then weighed pre- and post-preparation with delta weight (Δ wt = wt pre − wt post) and data were documented for statistics evaluation.

Results
Resin canals prepared using Fanta AF One rotary system showed significantly higher weight loss than Azure rotary system in both rotation and reciprocation (P < 0.001). Insignificant difference was reported for rotation and reciprocation movements in both file systems.

Conclusion
The instrument’s cross section revealed a more significant impact on cutting efficiency than the motion used.

PURPOSE To provide expert guidance to clinicians and policymakers in three resource-constrained settings on diagnosis and staging of adult women with ovarian masses and treatment of patients with epithelial ovarian (including fallopian tube and primary peritoneal) cancer. METHODS A multidisciplinary, multinational ASCO Expert Panel reviewed existing guidelines, conducted a modified ADAPTE process, and conducted a formal consensus process with additional experts. RESULTS Existing sets of guidelines from eight guideline developers were found and reviewed for resource-constrained settings; adapted recommendations from nine guidelines form the evidence base, informing two rounds of formal consensus; and all recommendations received ≥ 75% agreement. RECOMMENDATIONS Evaluation of adult symptomatic women in all settings includes symptom assessment, family history, and ultrasound and cancer antigen 125 serum tumor marker levels where feasible. In limited and enhanced settings, additional imaging may be requested. Diagnosis, staging, and/or treatment involves surgery. Presurgical workup of every suspected ovarian cancer requires a metastatic workup. Only trained clinicians with logistical support should perform surgical staging; treatment requires histologic confirmation; surgical goal is staging disease and performing complete cytoreduction to no gross residual disease. In first-line therapy, platinum-based chemotherapy is recommended; in advanced stages, patients may receive neoadjuvant chemotherapy. After neoadjuvant chemotherapy, all patients should be evaluated for interval debulking surgery. Targeted therapy is not recommended in basic or limited settings. Specialized interventions are resource-dependent, for example, laparoscopy, fertility-sparing surgery, genetic testing, and targeted therapy. Multidisciplinary cancer care and palliative care should be offered. Additional information can be found at www.asco.org/resource-stratified-guidelines . It is ASCO's view that health care providers and health care system decision makers should be guided by the recommendations for the highest stratum of resources available. The guideline is intended to complement but not replace local guidelines. [Media: see text]

Authors: Kim Hyunzu , Han Jeong Uk , Lee Woojoo , Jeon Yoon Sang , Jeong Jimyeong , Yang Chunwoo , Uhm Jae Woung , Kim Youngjun 
Published: June 2021

BACKGROUND:
Relative to interscalene block, superior trunk block (STB) provides comparable analgesia and a reduced risk of hemidiaphragmatic paralysis. However, the incidence of hemidiaphragmatic paralysis remains high when a standard volume (15 mL) of local anesthetic is used. This study aimed to evaluate the effects of local anesthetic volume of STB on the incidence of phrenic nerve palsy, as well as its analgesic efficacy following arthroscopic shoulder surgery.

METHODS:
Patients scheduled for elective arthroscopic shoulder surgery were randomized to receive ultrasound-guided STB using either 5- or 15-mL 0.5% ropivacaine before general anesthesia. The primary outcome was the incidence of hemidiaphragmatic paralysis at 30 minutes after block. The secondary outcomes were pulmonary function, grade of sensory and motor blockade, pain score, opioid consumption, adverse effects, and satisfaction.

RESULTS:
Relative to standard-volume STB, low-volume STB was associated with a lower incidence of hemidiaphragmatic paralysis after block (14.3 [4.8%–30.3%] vs 65.7 [46.8%–80.9%]; difference 51.4% [95% confidence intervals {CIs}, 29.0%–67.1%]; P < .0001) and at the postanesthesia care unit (9.4% vs 50.0%; difference 40.6 [95% CI, 18.9%–57.7%]; P = .0004). Pulmonary function was also better preserved in the low-volume group than in the standard-volume group. The extent of the sensory and motor blocks was significantly different between the groups. Pain-related outcomes, satisfaction, and any adverse events were not significantly different between the groups.

CONCLUSIONS:
Low-volume STB provided a lower incidence of hemidiaphragmatic paralysis with no significant difference in analgesic efficacy relative to standard-volume STB for arthroscopic shoulder surgery.
Psychological resources in male prisoners: an application of the growth resources model
Authors: Piotrowski Przemysław , Pasowicz Maciej 
Published: June 2021

Aim of the studyThe main goals of this article are to describe the Growth Resources Model and to present the preliminary results of a research project that applied this model to an actual male prison population.Subject or material and methodsThe study was conducted in two prisons in Southern Poland – 37 inmates took part in it. To compare the results with a control group, 34 men that had never been in prison were also tested with the GRQ form.ResultsThe results indicate that prisoners put a high value on their psychological resources, with positive emotions being of highest importance. Furthermore, prisoners exhibit less trust in others than non-prisoners.DiscussionThe dominance of positive emotions and a high evaluation of personal psychological resources are surprising characteristics of inmates. The key to the analysis of the results seems to be the notion of self-enhancement. The term can be used both in the context of self-promotion and self-protection. Maintaining a positive self-image is often related to a preference for information consistent with such positive self-image, even if this requires a biased interpretation or unrealistic reinterpretation of features or events. When a person intends to act contrary to his or her own image, there are various ways of reducing cognitive dissonance that allow such incongruous behaviour while maintaining a positive self-image.ConclusionsWe argue that the Growth Resources Model can be used in the context of criminal psychology and social rehabilitation.

Published: June 2021

Aim of the studyThe aim of the study was to point to the determinants of school achievement in adolescent studentsSubject or material and methodsTo answer the research question - which predictors can explain school achievements in adolescents divided by gender - data was collected from 81 subjects using the Pressure Measurement Scale – PMS-18, Family Relations Questionnaire (FRQ) and the students’ average term score was taken into account.ResultsIn comparison with the boys, the girls’ grade point average results were significantly higher (p = 0.019).DiscussionIn the studied sample of girls, however, neither resilience, nor dimensions of their relationship with the mother co-impacted the girls’ school performance. Nevertheless, the model in which all predictors were introduced turned out to be significant on the level of tendency.ConclusionsThe obtained results showed that the significant factors impacting school achievements of boys include, apart from high resilience, the dimension of autonomy/control in their relationship with the mother.

Published: June 2021

BackgroundPrevious studies have established that sex workers experience discrimination and stigma within healthcare settings, limiting their access and receipt of culturally safe care. These barriers impact sex workers’ ability and desire to routinely engage with the healthcare system. Community empowerment interventions that are culturally safe offer an effective strategy to improve access to services and health outcomes for sex workers.ObjectivesThis project was designed to inform the development of community empowerment interventions for sex workers by understanding their self-management, health promotion, and harm reduction needs.MethodsIn-depth interviews (N = 21) were conducted with sex workers in Chicago. Transcripts of individual interviews were analyzed in Dedoose using rapid content analysis.ResultsParticipants had a mean age of 32.7 years; 45% identified as White, 20% as Black, 15% as Latinx, and 20% as multiple races; 80% identified as Queer. A total of 52% of participants identified as cisgender women, 33% as transgender or gender fluid, 10% as cisgender men, and 5% declined to answer. Themes of self-management practices, stigmatizing and culturally unsafe experiences with healthcare providers, and the prohibitive cost of healthcare emerged as consistent barriers to routinely accessing healthcare. Despite identifying patient-centered care as a desired healthcare model, many participants did not report receiving care that was respectful or culturally responsive. Themes also included developing strategies to identify sex worker-safe care providers, creating false self-narratives and health histories in order to safely access care, and creating self-care routines that serve as alternatives to primary care.ConclusionOur findings demonstrate how patient-centered care for sex-workers in Chicago might include holistic wellness exercises, accessible pay scales for services, and destigmatizing healthcare praxis. Focus on culturally safe healthcare provision presents needs beyond individualized, or even community-level, interventions. Ongoing provider training and inbuilt, systemic responsivity to patient needs and contexts is crucial to patient-centered care.

The antidepressant activity of Spathodea campanulata flowers was evaluated in mice and in silico. When tested at doses of 200 and 400 mg/kg, the methanol extract of S. campanulata (MESC) showed dose-dependent antidepressant activity in the force swim test (FST), tail suspension test (TST), lithium chloride-induced twitches test and the open field test. In FST and TST, animals treated with MESC demonstrated a significant decrease in the immobility period compared to the control group. The lithium chloride-induced head twitches were significantly reduced following administration of MESC. The latter, at the dose of 400 mg/kg, also significantly reduced locomotor activity. Following administration of MESC, changes in the levels of serum corticosterone, and of norepinephrine, dopamine, serotonin, 4-hydroxy-3-methoxyphenylglycol (MHPG), 4-dihydroxyphenylacetic acid (DOPAC), and 5-hydroxyindoleacetic acid (5-HIAA) were measured in different brain regions using HPLC. The presence of spatheoside A (m/z 541) and spatheoside B (m/z 559) in MESC was detected using HPLC/ESI-MS. These two iridoids demonstrated a high predictive binding affinity for the active site of the type A monoamine oxidase (MAO-A) enzyme with scores of 99.40 and 93.54, respectively. These data suggest that S. campanulata flowers warrants further investigation as a source of novel templates for antidepressive drugs.

Published: June 2021

The wine industry in Georgia produces vast amounts of grape pomace that is currently mostly wasted, while only a minor amount is used for distilling alcohol. The study was carried out on the grape pomace from the three most widely used grapevine sorts (Vitis vinifera var. Rkatsiteli, V. vinifera var. Saperavi, V. labrusca var. Isabella) in Georgia, and quantities of tocopherols and antioxidants were evaluated. The antioxidant activity was assessed by diphenyl-picrylhydrazyl (DPPH) and measurement of visible light absorption at 515 nm, and tocopherol was measured by absorption at 470 nm via a spectrophotometer. The results indicated that the grape pomace contains considerable tocopherols and antioxidant activity. However, the antioxidant activity had slightly been decreased. These results suggest that grape pomace can be an economically attractive resource for the pharmaceutical and food industries. Utilization of grape pomace for producing pharmaceutical and cosmetic goods with tocopherol and antioxidants can solve two problems: it can recycle waste and develop new profitable businesses in biotechnology.

Aim of the present study was to determine the In-vitro antibacterial activity of ethanolic extract of E. globulus leaves against common multidrug resistant poultry pathogens. Phytochemical analysis through HPLC revealed that kaempeferol (7.315min) followed by querecetin (6.655min) and myrecetin (3.655min). Percent area of kaempeferol (6826.88%) was highest, followed by myrecetin (5516.22%) and querecetin (163.748%). Phytochemical investigation of ethanolic extract of E. globulus leaves through GCMS showed highest retention time (min) Î±-pinene (20.43) and Î±-terpineol (20.15) accompanied by spathulenol (11.97), piperitone (11.04). The ethanolic extracts of E. globulus leaves showed a highest zone of inhibition against S. pullorum SP6; 20.64± 2.08, E. coli SE 12; 19.75± 2.83, C. perfringens type A (CPM38-01); 19.46± 2.02. The highest level of MIC of E. globulus noted were against S. gallinarum S22; 133.37±53.294, S. gallinarum S1; 130.20±45.10, S. gallinarum S4; 129.47±24.182, S. gallinarum S3; 126.83±72.392. In conclusion, the study confirmed that the ethanolic extract of E. globulus is composed of active ingredients having antibacterial activity and can be referred as an alternate to antibiotics.
