AbstractBackground and purposeThe aim of this clinical study was to investigate the clinical long-term and patient-reported outcome of dental implants in patients with oral cancer. In addition, analysis of the influence of radiation therapy, timing of implant insertion, and augmentation procedures on implant survival was performed.Material and methodsThis retrospective study investigated the clinical outcome of 711 dental implants in 164 oral cancer patients, inserted by experienced surgeons of the Department of Oral and Maxillofacial Surgery, University Medical Center Mainz, Germany. Oral health-related quality of life (OHRQoL) was evaluated.ResultsCumulative 5-year and 10-year implant survival rates for all included implants were 87.3% and 80.0%. Implants placed straight after ablative surgery (primary implant placement) and implants placed after completing the oncologic treatment (secondary implant placement) showed a comparable implant survival (92.5% vs. 89.5%; p = 0.635). Irradiation therapy had no significant influence on implant survival of secondary placed implants (p = 0.929). However, regarding implant site (native bone vs. augmented bone) and radiation therapy (non-irradiated bone vs. irradiated bone), implants inserted in irradiated bone that received augmentation procedures showed a statistically significant lower implant survival (p < 0.001). Patients reported a distinct improvement in OHRQoL.ConclusionsPromising long-term survival rates of dental implants in patients after treatment of oral cancer were seen. In addition, patients benefit in form of an improved OHRQoL. However, bone augmentation procedures in irradiated bone may result in an impaired implants’ prognosis.

Published: July 2021

Abstract
Background
Laparoscopic transabdominal preperitoneal patch (TAPP) is now commonly used in the repair of inguinal hernia. Barbed suture can be a fast and effective method of peritoneal closure. We report two rare cases of small bowel obstruction and perforation caused by barbed suture after TAPP.

Cases
Patient 1 is a 45-year-old man who underwent laparoscopic repair of a right inguinal hernia. Barbed suture was used to close the peritoneal defect. At 47 days after the operation, he was diagnosed with a small bowel obstruction caused by an elongated tail of the barbed suture. Emergency laparoscopic exploration was performed for removal of the embedded suture and detorsion of the volvulus. The second patient is a 50-year-old man who was admitted with a small bowel perforation one week after TAPP herniorrhaphy. Emergency exploration revealed that the tail of the barbed suture had pierced the small intestine, causing a tiny perforation. After cutting and releasing the redundant tail of the barbed suture, the serosal and muscular defect was closed with 2 absorbable single-knot sutures. Both patients have recovered well. Finally, we searched the PubMed database and reviewed the literature on the effectiveness and safety of barbed suture for TAPP.

Conclusions
Surgeons should understand the characteristics of barbed suture and master the technique of peritoneum closure during TAPP in order to reduce the risk of bowel obstruction and perforation.

Abstract
Background
The narrowness of the thoracic inlet is often a problem in retrosternal reconstruction after esophagectomy. We report here three cases in which compression of the gastric conduit behind the sternoclavicular joint possibly caused anastomotic leakage.

Case presentations
The first case was a 71-year-old man who underwent subtotal esophagectomy for upper esophageal cancer followed by retrosternal reconstruction. On postoperative day 2, he developed septic shock and underwent reoperation because of a necrotic gastric conduit. The tip of the conduit above the manubrium was necrotic due to strangulation as a result of compression by the sternoclavicular joint. The second and third cases were a 50-year-old woman and a 71-year-old man who underwent subtotal esophagectomy for middle and lower esophageal cancer, respectively, followed by retrosternal reconstruction. Despite indocyanine green fluorescence imaging indicating adequate blood flow in both cases, the tip of the conduit appeared pale and congested because of compression by the sternoclavicular joint after anastomosis. Postoperatively, these two patients developed anastomotic leakage that was confirmed endoscopically on the ventral side of the gastric wall that had been pale intraoperatively.

Conclusions
When performing reconstruction using the retrosternal route after esophagectomy, it is important to ensure that compression by the sternoclavicular joint does not have an adverse impact on blood flow at the tip of the gastric conduit.
Comparing the racialization of Central-East European migrants in Japan and the UK
Authors: Drnovšek Zorko Špela , Debnár Miloš 
Published: July 2021

AbstractThe article deploys the lens of the race-migration nexus (Erel et al., Ethnic and Racial Studies 39:1339–1360, 2016) to compare the racialization of migrants in the UK and Japan. It draws on qualitative data on the experiences of Central-East European (CEE) migrants in the two countries to unpack how whiteness is constructed in relation to different histories and patterns of immigration in each national context. While CEE migrants in Japan benefit from being perceived as implicitly white and Western ‘foreigners’, their whiteness represents a form of enduring exclusion from the ethno-nationalist Japanese society. In the UK, changing political contexts and internal European hierarchies of whiteness contribute to CEE migrants’ ambiguous position in an increasingly anti-migrant society. By comparing the mechanisms of racialization in each country through the analytics of visibility and exclusion, the article furthers ongoing debates about the intersections of race and migration. It furthermore extends the comparative analysis of whiteness to a non-Western setting, making a significant contribution to the study of local/global articulations of race.

Published: July 2021

AbstractBackgroundIn the field of craniofacial tumor surgery, an adequately performed excision, despite being a life-saving procedure, is only a first step to successful treatment. During such a procedure, the main goal is to completely remove the lesion, paying less attention to factors contributing to future rehabilitation possibilities. One ty 2of the possibilities for prosthetic rehabilitation of such cases is utilizing one-piece implants with bicortical anchorage.Case presentationThis case report presents a case of a 48-year-old patient with oral squamous cell carcinoma (OSCC). The treatment protocol consisted of radical surgery to remove the tumor, and intraoral and extraoral rehabilitation with a single framework prosthesis anchored with one-piece implants. Moreover, the intraoral stomatognathic deformity was corrected with a fixed implant-retained prosthesis, and the extraoral defect was covered with a removable epithesis.ConclusionsThe use of one-piece implants with bicortical anchorage may be an additional tool in reconstructing maxillofacial defects. Properly executed treatment may improve the esthetics, speech, masticatory function, muscle support, and the overall quality of life of patients with extensive defects in the maxillofacial region.

Published: July 2021

AbstractToday, alternative fuels are seen as a critical area of sustainable technological growth in maritime transport. The International Maritime Organisation (IMO), the United Nations body for maritime issues and other international bodies are in the process of amending and updating the regulations applicable to the shipping industry. Greece is ready to enter the era of liquefied natural gas (LNG) and electricity as marine fuels, as Eastern Mediterranean projects are heading towards adopting these alternative fuels. This study aims to explore the intention of the Greek stakeholders in accepting and using LNG and electricity as alternative fuels. The research objectives are to identify, analyse and evaluate the determinants that influence the intention to accept, diffuse and use alternative fuels, LNG and electricity for marine propulsion, and develop, construct and validate a hybrid model that can be used for future study. This research will clarify possible challenges or barriers to the implementation of technology by stakeholders and contribute to a deeper understanding of the green shipping network. It will also highlight the role of key players in the diffusion phase of technological innovation and the technology itself and its characteristics. Moreover, this research will suggest a unified model using the expansive Technology Acceptance Model (TAM) in conjunction with the Innovation Diffusion Theory (IDT) and external variables affecting LNG and electricity 1) to investigate the intent of implementing the use of such alternative fuels and 2) to inform policymakers concerning sustainable shipping.

Published: July 2021

AbstractBackgroundHealth literacy plays a prominent role in empowering individuals for prevention as well as management of non-communicable diseases (NCDs). However, there is paucity of information on the health literacy of patients with non-communicable diseases in Ethiopia. Therefore, this study aimed to assess communicative health literacy and associated factors in patients with NCDs on follow-up at Jimma Medical Center (JMC), Ethiopia.MethodsA cross-sectional study was conducted from 4 May 2020 to 4 July 2020 with 408 randomly selected adult patients, attending outpatient department of JMC in Ethiopia. The final sample size was obtained by using single population proportion formula. All patients with NCDs who were on follow-up at chronic illness clinic, JMC, were used as a source population. All eligible patients with NCDs who fulfilled the inclusion criteria were included in this study. A simple random sampling technique was used to recruit study participants. Data were collected through structured interviewer administered questionnaires on the six of nine health literacy domains using Health Literacy Questionnaire (HLQ) containing 30 items, socio-demographic and socio-economic characteristics, disease-related factors, and health information sources. Multivariable logistic regression was executed to determine the associations.ResultDescriptive analysis shows more than half of the respondents in four of the six health literacy domains had high communicative health literacy level (CHLL). The proportion of people with high CHLL across each of the domains was as follows: health care provider support (56.1%), social support for health (53.7%), active engagement with a healthcare provider (56.1%), and navigating healthcare system (53.4%). We found educational status was significantly associated with five of six health literacy domains whereas number of sources was associated with four of six health literacy domains.ConclusionThe overall findings of the current study indicate that health literacy levels vary according to socio-demographic and disease characteristics of patients. Thus, healthcare professionals should assess patients’ health literacy level and tailor information and support to the health literacy skills and personal context of their patients.
Creating idiometric short-form measures of cognitive appraisal: balancing theory and pragmatics
Authors: Schwartz Carolyn E. , Stark Roland B. , Rapkin Bruce D. 
Published: July 2021

Abstract
Background
The Rapkin and Schwartz appraisal theory and measure provided a path toward documenting response-shift effects and describing individual differences in ways of thinking about quality of life (QOL) that distinguished people in different circumstances. Recent work developed and validated the QOL Appraisal Profileversion 2 (QOLAPv2), an 85-item measure that taps response-shift-detection domains of Frame of Reference, Standards of Comparison, Sampling of Experience, and Combinatory Algorithm. Recent theoretical work proposed that appraisal measurement constitutes a new class of measurement (idiometric), distinct from psychometric and clinimetric. To validate an idiometric measure, one would document that its items reflect different circumstances and population characteristics, and explain variance in QOL. The present work sought to develop idiometric short-forms of the QOLAPv2 item bank by examining which items were most informative, retaining the appraisal-domain structure.

Methods
This secondary analysis (n = 1481) included chronically-ill patients and their caregivers from a longitudinal web-based survey (mean follow-up 16.6 months). Data included the QOLAPv2, the Center for Disease Control Healthy Days Core Module, the PROMIS-10 Global Health, and demographic/medical variables. Appraisal items were measured at baseline (relevant to understanding cognitive appraisal processes); and with change scores (sensitive to response-shift effects). Multivariate analysis of covariance examined what demographic and health-status change variables were reflected by each of 85 appraisal items (in five sets), as dependent variables, and other demographic/medical variables. Multiple linear regression examined how appraisal items explained variance in global physical- and mental-health change, after covariate adjustment. A tally summarized item performance across all five sets of cross-sectional and longitudinal analyses.

Results
The vast majority (i.e., 80%) of the QOLAPv2 items performed well across the analyses presented. Using a relatively strict criterion of explaining meaningful variance across 60% of analyses, one would retain 68 items. A more lenient criterion (40%) would retain 71.

Conclusions
The present study provides heuristics to support investigators’ creating ‘discretionary’ QOLAPv2 short-forms to fit their study aim and amplifying individual differences in the cognitive processes underlying QOL. This approach enables adapting the measure to the study population, as per the expectation that respondent populations differ in the predominant cognitive processes used.

Authors: Sehsah Radwa , Gaballah Mohammed Hassan , El-Gilany Abdel-Hady , Albadry Ahmed A. 
Published: July 2021

Abstract
Background
Forensic physicians are confronted daily with highly stressful and traumatic duties. With repeated exposure, they are at risk of psychological distress, especially burnout. The current study’s objective was to measure the prevalence of burnout and its associated factors among Egyptian forensic physicians, describe their coping strategies, and the correlation between burnout levels and coping strategies. A cross-sectional study on Egyptian forensic physicians was carried out using a self-administered questionnaire. It included personal and occupational data, Maslach Burnout Inventory, and the Brief COPE Inventory. Multivariable logistic regression was performed to identify significant independent predictors of burnout. The correlation between burnout and coping was examined.

Results
Moderate/high levels of burnout were scored by 72.9 %, 51.9%, and 75.9% of forensic physicians in the emotional exhaustion, depersonalization, and personal accomplishment subscales, respectively. The significant independent predictors of high emotional exhaustion were being a forensic examiner (AOR, 3.1; 95% CI, 1.3–7.6) and facing stressful job duties more than five times per month (AOR, 4.4; 95% CI, 1.6–12.3). The predictor of high depersonalization was being a forensic examiner (AOR, 22.8; 95% CI, 8.0–64.8), and for low personal accomplishment was being a female (AOR, 3.0; 95% CI, 1.3–6.8). The most frequent coping strategies adopted by forensic physicians were adaptive coping.

Conclusions
Egyptian forensic physicians have a high prevalence of burnout. Forensic examiners, females with high exposure to stressful duties are more likely to have high burnout levels. Thus, psychoeducation and psychological support services should be applied and made easily accessible to them.

Abstract
Background
SARS CoV-19 was declared as a pandemic by the World Health Organization (WHO), raising up challenges on various levels ranging from therapeutics to diagnostics. The conventional autopsy technique may pose a health hazard to health care workers. A minimally invasive autopsy technique can diminish this hazard.

Materials and methods
Between August and November 2020, 51 patients who were suffering from Covid-19 at the time of their demise were included. A novel minimally invasive ultrasound-guided technique for procuring tissue samples of major organs was employed which were thereafter subject to histopathological examination. A detailed review of the course in hospital was noted. An analysis was performed to correlate the cause of death ascertained from our minimally invasive technique with the cause of death ascertained clinically.

Results
There was adequate tissue sampling in 45 cases, where the minimally invasive autopsy technique confirmed the cause of death in all 45 cases (100%) and made it more specific in 5 cases (11.11%).

Conclusion
Minimally Invasive Autopsy is an easily reproducible technique which has the potential to strengthen the probable the cause of death with reasonable certainty while ensuring safety and ethics.

Published: July 2021

Abstract
Background
Cadmium (Cd) is a known metallohormone which mimics the action of steroid hormones with adverse effect on testicular function. It is highly toxic and a prevalent environmental contaminant with no conventional antidote. This study investigates the possible ameliorative effects of Thymus vulgaris extract on testicular toxicity induced by Cd in male rats.

Results
The testicular and epididymal weights, serum concentration of follicle stimulating hormone, luteinizing hormone, and testosterone were significantly (p ≤ 0.05) lower in the cadmium-treated group compared to the control. Necrosis of germ cells of the seminiferous tubules was observed in the testicular tissues of the cadmium-treated group. Administration of extract showed mild but non-significant (p ≥ 0.05) protective effect on the cadmium-induced decrease in sex hormones and sperm count as well as oxidative stress and histological changes.

Conclusion
Thymus vulgaris leaf extract had weak ameliorative effect on cadmium-induced testicular injury in rats but with promising antioxidant activity.

Published: July 2021

Abstract
Background
Cotton fibers are single-celled extensions of the seed epidermis, a model tissue for studying cytoskeleton. Tubulin genes play a critical role in synthesizing the microtubules (MT) as a core element of the cytoskeleton. However, there is a lack of studies concerning the systematic characterization of the tubulin gene family in cotton. Therefore, the identification and portrayal of G. hirsutum tubulin genes can provide key targets for molecular manipulation in cotton breeding.

Result
In this study, we investigated all tubulin genes from different plant species and identified 98 tubulin genes in G. hirsutum. Phylogenetic analysis showed that tubulin family genes were classified into three subfamilies. The protein motifs and gene structure of α-, β-tubulin genes are more conserved compared with γ-tubulin genes. Most tubulin genes are located at the proximate ends of the chromosomes. Spatiotemporal expression pattern by transcriptome and qRT-PCR analysis revealed that 12 α-tubulin and 7 β-tubulin genes are specifically expressed during different fiber development stages. However, Gh.A03G027200, Gh.D03G169300, and Gh.A11G258900 had differential expression patterns at distinct stages of fiber development in varieties J02508 and ZRI015.

Conclusion
In this study, the evolutionary analysis showed that the tubulin genes were divided into three clades. The genetic structures and molecular functions were highly conserved in different plants. Three candidate genes, Gh.A03G027200, Gh.D03G169300, and Gh.A11G258900 may play a key role during fiber development complementing fiber length and strength.
Imaging findings and 4 years follow-up of adrenal cavernous hemangioma: a case report
Authors: Testini Valentina , Eusebi Laura , Giannubilo Willy , Ferrara Vincenzo , Bartelli Francesco , Guglielmi Giuseppe 
Published: July 2021

Abstract
Background
Adrenal hemangioma is a rare and non-functional benign tumor. Since the first case in 1955, approximately 90 cases have been reported in literature frequently presenting as a large and incidentally discovered retroperitoneal mass or as a result of hemorrhage caused by spontaneous rupture.

Case presentation
A 69-year-old man was admitted to our hospital for right hypocondrium pain and anemia. A computed tomography (CT) scan was performed and a large right adrenal mass measured 18 cm was found.
The patient underwent laparoscopic right adrenalectomy. Histopathological diagnosis revealed a cavernous adrenal hemangioma.

Conclusion
Cavernous hemangiomas are uncommon tumors. We reported a case of adrenal cavernous hemangioma incidentally discovered by ultrasound and CT. In the case of finding adrenal masses, cavernous hemangiomas, although rare, should be considered a possible diagnosis.
The appropriate treatment is surgical resection to rule out any potential for malignancy, to relieve symptoms secondary to the mass effect, and to prevent complications such as retroperitoneal bleeding.
