Abstract
Objective
It has been reported that papillary thyroid carcinoma (PTC) patients with lymph node metastasis (LNM) are largely associated with adverse outcomes. The present study aimed to assess the correlation between the number of metastatic lymph nodes (NMLNs) and clinical prognosis in patients with PTC.

Methods
We retrospectively reviewed the medical records of patients with PTC who underwent initial thyroid cancer surgery in Renmin Hospital of Wuhan University between 2017 and 2019. A total of 694 patients with PTC and cervical lymph node dissection as well as a total checked number of lymph nodes ≥ 5 were involved in this study. The clinicopathological characteristics of patients were compared according to NMLNs, the number of central cervical lymph nodes (CLNs) and the number of lateral lymph nodes (LLNs).

Results
NMLNs > 5, CLNs > 5 and LLNs > 5 were 222 (32.0%), 159 (24.3%) and 70 (10.1%) seen in the analyzed samples, respectively. Young patients, patients with larger tumor diameter, bilaterality, multifocality and gross extrathyroidal extension (ETE) were more inclined to NMLNs > 5, CLNs > 5 and LLNs > 5 (P < 0.05). It was found that the recurrence-free survival among pN1 patients was significantly discrepant between different groups (NMLNs ≤ 5/5: P = 0.001; LLNs ≤ 5/5: P < 0.001). In multivariate logistic regression analysis, patients aged < 55 years (OR = 1.917), primary tumor size > 10 mm (OR = 2.131), bilaterality (OR = 1.889) and tumor gross ETE (OR = 2.759) were independent predictors for high prevalence of total NMLNs > 5 (P < 0.05). Specially, patients aged < 55 years (OR = 2.864), primary tumor size > 10 mm (OR = 2.006), and tumor gross ETE (OR = 2.520) were independent predictors for high prevalence of CLNs > 5 (P < 0.01); Bilaterality (OR = 2.119), CLNs > 5 (OR = 6.733) and tumor gross ETE (OR = 4.737) were independent predictors for high prevalence of LLNs > 5 (P < 0.05).

Conclusions
In conclusion, it is evident that NMLNs is related to the invasive clinicopathological features and adverse outcome of patients with PTC which should be correctly evaluated to provide an appropriate guidance for reasonable treatment and careful follow-up.

Abstract
Background
Several studies have discussed various methods of prepectoral direct-to-implant (DTI) breast reconstruction using an acellular dermal matrix (ADM) prosthesis to achieve full coverage. However, methods for anterior coverage have rarely been reported. In this study, prepectoral DTI breast reconstruction with complete anterior implant coverage was performed using a square piece of ADM. This study aimed to introduce our prepectoral DTI technique and determine its functional and cosmetic outcomes as well as compare them with those of existing subpectoral DTI techniques.

Methods
This prospective comparative study focused on 29 patients (35 breasts) and 34 patients (35 breasts) who underwent breast reconstruction via subpectoral implant insertion (control group) and anterior coverage prepectoral implant insertion (anterior coverage group), respectively. Postoperative complications were noted, and breast symmetry was evaluated using the Vectra H2 three-dimensional scanner. The modified Kyungpook National University Hospital Breast-Q (KNUH Breast-Q) scale was used to assess the patient’s subjective satisfaction with the reconstruction and postoperative quality of life.

Results
No remarkable differences in terms of complications (seroma, skin necrosis, nipple–areola complex necrosis, hematoma, capsular contracture, and infection) were noted in both groups. Compared with controls, considerably better results were observed among those in the anterior coverage group in terms of the mean drain removal period. Furthermore, those in the anterior coverage group showed greater symmetry on three-dimensional scans than the controls; however, this was not statistically significant. Subjective satisfaction and postoperative quality of life measured using the KNUH Breast-Q scale were not significantly different between both groups.

Conclusions
Considering its stability, faster recovery time, and cosmetic benefit, prepectoral breast reconstruction with anterior implant coverage using a single, large ADM is a good choice to perform breast reconstruction with implant insertion in patients who have undergone mastectomy.

Published: June 2022

AbstractRegardless of the advances in surgical techniques, parastomal hernia is still an inevitable complication for many patients with low rectal cancer undergoing abdominal perineal resection (APR). Extraperitoneal colostomy (EPC) seems to be a effective method to reduce the risk of parastomal hernia. We propose a new approach to simplify and standardize laparoscopic EPC to make this operation easy to perform. We used the technique of laparoscopic TEP groin hernia repair to produce an extraperitoneal tunnel, which can not only facilitate precise visualization of the extraperitoneal tunnel but also utilize the intact posterior rectus abdominis sheath as biologic materials to maintain soft-tissue augmentation, with a satisfactory result. With laparoscopy, we can create adequate space without insufficient dissection of the extraperitoneal tunnel while avoiding damage to the retrorectus sheath. At the time of writing, we had performed this method in four patients, without any complications. This technique is effective at preventing parastomal hernia without extra costs.
Does clinical experience with dental traumatology impact 2D and 3D radiodiagnostic performance in paediatric dentists? An exploratory study
Authors: Van Gorp Gertrude , Lambrechts Marjan , Jacobs Reinhilde , Declerck Dominique 
Published: June 2022

Abstract
Background
The aim of this study is to evaluate the impact of experience with traumatic dental injuries (TDI) on paediatric dentists’ performance and self-assessed confidence when radiodiagnosing traumatic dental injuries (TDI) and to explore whether this is influenced by the imaging technique used (2D versus 3D).

Materials and methods
Both 2D and 3D radiological images of young anterior permanent teeth having experienced dental trauma were assessed randomly by a panel of paediatric dentists using structured scoring sheets. The impact of level of experience with dental traumatology on radiological detection, identification and interpretation of lesions and on observer’s self-assessed confidence was evaluated. Findings were compared to benchmark data deriving from expert consensus of an experienced paediatric endodontologist and dentomaxillofacial radiologist. Results were analysed using generalized linear mixed modelling.

Results
Overall, observers performed moderately to poor, irrespective of their level of TDI experience and imaging modality used. No proof could be yielded that paediatric dentists with high TDI experience performed better than those with low experience, for any of the outcomes and irrespective of the imaging modality used. When comparing the use of 3D images with 2D images, significantly higher sensitivities for the detection and correct identification of anomalies were observed in the low experienced group (P < 0.05). This was not the case regarding interpretation of the findings. Self-assessed confidence was significantly higher in more experienced dentists, both when using 2D and 3D images (P < 0.05).

Conclusion
There was no proof that paediatric dentist’s higher experience with TDI is associated with better radiodiagnostic performance. Neither could it be proven that the use of Cone Beam Computed Tomography (CBCT) contributes to an improved interpretation of findings, for any experience level. More experienced dentists feel more confident, irrespective of the imaging modality used, but this does not correlate with improved performance. The overall poor performance in image interpretation highlights the importance of teaching and training in both dental radiology and dental traumatology.

AbstractBackgroundPrevious studies in our laboratory in ex vivo assays have demonstratedH. hemerocallideaextract as potential antidiabetic agent through increased insulin release from pancreatic beta cells. Thus, for this study the early stage type II spontaneous diabetic mutant mice model was used to evaluate and determine the degree of the antidiabetic efficacy ofH.hemerocallidea.MethodsEight-weeks-old type II spontaneous pre-diabetic mutant BKS-Leprdb mice were fed with feed supplemented with eitherH.hemerocallideaextract, isolated compound (β-sitosterol) or chlorpropamide (positive control) for 4 weeks. The haematological parameters, clinical chemistry, glucose tolerance, feed intake, faecal output and body weights were measured.ResultsThe blood glucose concentrations of all the animals treated with plant extract, β-sitosterol compound and non-treated pre-diabetic animals did not return to baseline levels. Only the β-sitosterol treatment and positive control groups resulted in a respective small decrease of 5.8 and 5.2% in the mouse weights over the study period, with no significant changes (p > 0.05) in food intake. However, there was a general trend for decrease in faecal output for all the groups. Albumin, triglycerides, and total cholesterol levels in β-sitosterol and chlorpropamide-treated animals were lower, relative to untreated-animals. Animals fed with plant extract showed large amounts of internal fat. There were no significant changes (p > 0.05) in total serum protein, globulin, alanine aminotransferase, alkaline phosphatase, urea nitrogen and creatinine attributed to administration of treatments. In all groups, some animals showed lesions associated with cardiac puncture. Few animals except animals treated with plant extract, showed presence of a left-ventricular hypertrophic cardiomyopathy. The liver and kidneys for all groups appeared macroscopically normal and the thymuses were small (±2 mg). There were pathological signs in some of the animals particularly in myocardial fibres, renal tubular, glomerular, hepatocyte granularity and pancreas islets. However, there was no significance trend between the groups.ConclusionBased on the results, none of the treatments could be considered highly effective for the management of type II pre-diabetes as sole therapeutic intervention.

Published: June 2022

AbstractBackgroundIn a sudden cardiac arrest, starting CPR and applying an AED immediately are the two highest resuscitation priorities. Many existing mobile applications have been developed to assist users in locating a nearby AED. However, these applications do not provide indoor navigation to the AED location. The time required to locate an AED inside a building due to a lack of indoor navigation systems will reduce the patient’s chance of survival. The existing indoor navigation solutions either require special hardware, a large dataset or a significant amount of initial work. These requirements make these systems not viable for implementation on a large-scale.MethodsThe proposed system collects Wi-Fi information from the existing devices and the path’s magnetic information using a smartphone to guide the user from a starting point to an AED. The information collected is processed using four techniques: turn detection method, Magnetic data pattern matching method, Wi-Fi fingerprinting method and Closest Wi-Fi location method to estimate user location. The user location estimations from all four techniques are further processed to determine the user’s location on the path, which is then used to guide the user to the AED location.ResultsThe four techniques used in the proposed systemTurn detection,Magnetic data pattern matching,Closest Wi-Fi locationandWi-Fi fingerprintingcan individually achieve the accuracy of 80% with the error distance ± 9.4 m, ± 2.4 m, ± 4.6 m, and ± 4.6 m respectively. These four techniques, applied individually, may not always provide stable results. Combining these techniques results in a robust system with an overall accuracy of 80% with an error distance of ± 2.74 m. In comparison, the proposed system’s accuracy is higher than the existing systems that use Wi-Fi and magnetic data.ConclusionThis research proposes a novel approach that requires no special hardware, large scale data or significant initial work to provide indoor navigation. The proposed systemAEDNavcan achieve an accuracy similar to the existing indoor navigation systems. Implementing this indoor navigation system could reduce the time to locate an AED and ultimately increase patient survival during sudden cardiac arrest.

Authors: Pichon Latrice C. , Stubbs Andrea Williams , Teti Michelle 
Published: June 2022

Abstract
Background
The purpose of SNAP Out Stigma (SOS) was to design and implement a community-based intervention to reduce HIV-related stigma for people living with HIV (PLWH) in the Deep South. This region is a subset of 9 states including Memphis, Tennessee (project site) driving the epidemic in the United States. The purpose of this paper is to explain how PLWH in the U.S. South used Photovoice to communicate stigmatizing lived experiences and contextualize their intersection with multi-level sources of support.

Methods
PLWH attended one-on-one and/or group sessions with other PLWH. In Session 1, PLWH received a project overview, met other participants, received a camera and camera training, completed a standardized internalized stigma scale, discussed experiences of internalized stigma, and were instructed to take 3–10 pictures that captured stigma. In Session 2, PLWH discussed the pictures and their meaning. In Session 3, PLWH expanded on what they shared in previous sessions in a one-on-one interview. Thematic analysis captured key patterns of how PLWH experienced stigma.

Results
Forty-seven PLWH attended Session 1 and were issued a camera. Of those, 35 completed sessions 2 and 3. Participants self-identified as cis man who has sex with men (n = 18), ciswoman (n = 5), transwoman (n = 10), and non-binary (n = 2). Four emergent themes intersecting with internalizations of stigma were identified including: medical, social support, church, and self.

Conclusions
The SOS intervention created a safe space for PLWH to share lived experiences of stigmatization. Photovoice facilitated discussion topics ranging from healing and recovery to overcoming factors of social determinants of HIV. We identified trauma-informed growth as an area of future programs for PLWH.
Impact of integrated medication management program on medication errors in a medical center: an interrupted time series study
Authors: Chen Kuan-Lin , Hunag Chih-Fen , Sheng Wang-Huei , Chen Yu-Kuei , Wang Chi-Chuan , Shen Li-Jiuan 
Published: June 2022

Abstract
Background
Medication errors (MEs) are harmful to patients during hospitalization, especially elderly patients. To reduce MEs, an integrated medication management (IMM) model was developed in a 2500-bed medical center, allowing a clinical pharmacist to participate in the daily ward round and perform medication reconciliation and medication reviews. This study aimed to evaluate the impact of the IMM model on MEs and medication utilization using a quasi-experimental design.

Methods
We conducted an interrupted time-series study using the aggregated data of monthly admissions from two wards of a medical center, where one ward served as the intervention and the other served as the external control. The pre- and post-intervention phases comprised of 40 and 12 monthly observational units, respectively. The primary outcome was the mean number of ME reports, which were further investigated for different ME types. The mean number of daily inpatient prescriptions, mean number of daily self-prepared medications, and median daily medication costs were measured. All outcomes were measured per admission episode. Segmented regression was used to evaluate the level and slope changes in the outcomes after IMM model implementation, and subgroup analyses were performed to examine the effects on different groups.

Results
After IMM model implementation, the mean number of ME reports increased (level change: 1.02, 95% confidence interval [CI]: 0.68 to 1.35, P < 0.001). The number of reports has shown a dramatic increase in omissions or medication discrepancies, inappropriate drug choices, and inappropriate routes or formulations. Furthermore, the mean number of daily inpatient prescriptions was reduced for patients aged ≥75 years (level change: −1.78, 95% CI: −3.06 to −0.50, P = 0.009). No significant level or slope change was observed in the control ward during the post-intervention phase.

Conclusions
The IMM model improved patient safety and optimized medication utilization by increasing the reporting of MEs and decreasing the number of medications used.

Published: June 2022

AbstractBackgroundDefensive Medicine (DM) concept refers to all medical care provided by physicians without increasing the benefits to the patient, the primary purpose of which is to prevent the risk of litigation. Although several studies have been published investigating the occurrence of DM around the world, no review conducted on DM among physicians. Therefore, this study aims to summarize and map the available evidence on occurrence, types of behaviors, and reasons for practicing of DM among physicians and possible solutions and strategies to reduce DM in the literature.MethodsThis is a scoping review in which we searched Web of Science, Scopus, and PubMed in December 2021. Our target was original studies of any type that included data on DM among physicians between 2000 and 2021. We followed the JBI guideline for conducting a scoping review and for increasing the rigor of the study. First, the percentage was used to summarize the occurrence of DM, and then, findings related to types of behaviors and reasons for practicing DM and mitigation strategies were analyzed inductively in NVivo 10 in three stages.ResultsTwenty-seven studies were included in the review. The overall occurrence of DM practice ranged from 6.7 to 99.8%. Two types of DM behaviors including assurance and avoidance behaviors have been identified. The common reasons for practicing DM were categorized into four themes, patient-related reasons, physician-related reasons, organization-related reasons, and society-related reasons. The main strategies to prevent or reduce DM are structured training and education, restoring physician-patient relationships, reform of the health system, and reform of the liability system.ConclusionsThe vast majority of research studies were conducted in high-income countries, and studies are needed to measure this phenomenon and its consequences in depth in low- and middle-income countries. Various solutions and strategies are needed to reduce defensive behaviors such as structured training and education, restoring physician-patient relationships, reforming the health system, and reforming the liability system.KeywordsDefensive medicine, Defensive practice, Medical malpractice, Physicians, Scoping review
Person-centred care to prevent hospitalisations – a focus group study addressing the views of healthcare providers
Authors: Lyhne Cecilie Nørby , Bjerrum Merete , Jørgensen Marianne Johansson 
Published: June 2022

AbstractBackgroundThe primary healthcare sector comprises various health services, including disease prevention at local level. Research shows that targeted primary healthcare services can prevent the development of acute complications and ultimately reduce the risk of hospitalisations. While interdisciplinary collaboration has been suggested as a means to improve the quality and responsiveness of personal care needs in preventive services, effective implementation remains a challenge. To improve the quality and responsiveness of primary healthcare and to develop initiatives to support the interdisciplinary collaboration in preventive services, there is a need to investigate the views of primary healthcare providers. The aim of this study was to investigate perceptions of preventive care among primary healthcare providers by examining their views on what constitutes a need for hospitalisation, and which strategies are found useful to prevent hospitalisation. Further, to explain how interdisciplinary collaboration can be supported with a view to providing person-centred care.MethodsFive focus group interviews were conducted with 27 healthcare providers, including general practitioners, social and healthcare assistants, occupational therapists, physiotherapists, home care nurses, specialist nurses and acute care nurses. Interviews were transcribed, and analysed with qualitative content analysis.ResultsThree categories emerged from the analysis: 1) Mental and social conditions influence physical functioning and hospitalisation need, 2) Well-established primary healthcare services are important to provide person-centred care through interdisciplinary collaboration and 3) Interdisciplinary collaboration in primary healthcare services is predominantly focussed on handling acute physical conditions. These describe that the healthcare providers are attentive towards the influence of mental, social and physical conditions on the risk of hospitalisation, entailing a focus on person-centred care. Nevertheless, in the preventive services, interdisciplinary collaboration focusses primarily on handling acute physical conditions, which constitutes a barrier for interdisciplinary collaboration.ConclusionsBy focusing on the whole person, it could be possible to provide more person-centred care through interdisciplinary collaboration and ultimately to prevent some hospitalisations. Stakeholders at all levels should be informed about the relevance of considering mental, social and physical conditions to improve the quality and responsiveness of primary healthcare services and to develop initiatives to support interdisciplinary collaboration.
