Authors: Kim Moon Jong , Kim Ji Rak , Jo Jung Hwan , Kim Ju Sik , Park Ji Woon 
Published: February 2023

Objective The amount of online medical information available is rapidly growing and YouTube is considered as the most popular source of healthcare information nowadays. However, no study has been conducted to comprehensively evaluate YouTube videos related to temporomandibular disorders (TMD). So this study aimed to evaluate the content and quality of YouTube videos as a source of medical information on TMD. Method A total of 237 YouTube videos that were systematically searched using five keywords (temporomandibular disorders, tmd, temporomandibular joint, tmj, and jaw joint) were included. Included videos were categorized by purpose and source for analysis. The quality (DISCERN, Health on the Net (HON), Ensuring Quality Information for Patients (EQIP), and Global Quality Scale (GQS)) and scientific accuracy of video contents were evaluated. Results Total content, DISCERN, HON, EQIP, and GQS scores were 7.5%, 38.9%, 35.2%, 53.0%, and 48.6% of the maximum possible score, respectively. Only 69 videos (29.1%) were considered as “useful” for patients. News media, physician, and medical source videos showed higher evaluation scores than others. Quality evaluation scores were not significantly correlated or negatively correlated with public preference indices. In the ROC curve analysis, content and DISCERN score showed above excellent discrimination ability for high-quality videos based on GQS ( P < 0.001) and total score ( P < 0.001). Conclusions YouTube videos related to TMD contained low quality and scientifically inaccurate information that could negatively influence patients with TMD.

V617F allele burden in polycythemia vera: burden of proof
Authors: Moliterno Alison R. , Kaizer Hannah , Reeves Brandi N. 
Published: February 2023

Abstract
Polycythemia vera (PV) is a hematopoietic stem cell neoplasm defined by activating somatic mutations in the JAK2 gene and characterized clinically by overproduction of red blood cells, platelets, and neutrophils; a significant burden of disease-specific symptoms; high rates of vascular events; and evolution to a myelofibrosis phase or acute leukemia. The JAK2V617F variant allele frequency (VAF) is a key determinant of outcomes in PV, including thrombosis and myelofibrotic progression. Here, we critically review the dynamic role of JAK2V617F mutation burden in the pathogenesis and natural history of PV, the suitability of JAK2V617F VAF as a diagnostic and prognostic biomarker, and the utility of JAK2V617F VAF reduction in PV treatment.

Abstract
Background
Little information is available on the costs of respiratory syncytial virus (RSV) in Vietnam or other low- and middle-income countries. Our study estimated the costs of LRTIs associated with RSV infection among children in southern Vietnam.

Methods
We conducted a prospective cohort study evaluating household and societal costs associated with LRTIs stratified by RSV status and severity among children under 2 years old who sought care at a major pediatric referral hospital in southern Vietnam. Enrollment periods were September 2019–December 2019, October 2020–June 2021 and October 2021–December 2021. RSV status was confirmed by a validated RT-PCR assay. RSV rapid detection antigen (RDA) test performance was also evaluated. Data on resource utilization, direct medical and non-medical costs, and indirect costs were collected from billing records and supplemented by patient-level questionnaires. All costs are reported in 2022 US dollars.

Results
536 children were enrolled in the study, with a median age of 7 months (interquartile range [IQR] 3–12). This included 210 (39.2%) children from the outpatient department, 318 children (59.3%) from the inpatient respiratory department (RD), and 8 children (1.5%) from the intensive care unit (ICU). Nearly 20% (105/536) were RSV positive: 3.9 percent (21/536) from the outpatient department, 15.7% (84/536) from the RD, and none from the ICU. The median total cost associated with LRTI per patient was US$52 (IQR 32–86) for outpatients and US$184 (IQR 109–287) for RD inpatients. For RSV-associated LRTIs, the median total cost per infection episode per patient was US$52 (IQR 32–85) for outpatients and US$165 (IQR 95–249) for RD inpatients. Total out-of-pocket costs of one non-ICU admission of RSV-associated LRTI ranged from 32%-70% of the monthly minimum wage per person (US$160) in Ho Chi Minh City. The sensitivity and the specificity of RSV RDA test were 88.2% (95% CI 63.6–98.5%) and 100% (95% CI 93.3–100%), respectively.

Conclusion
These are the first data reporting the substantial economic burden of RSV-associated illness in young children in Vietnam. This study informs policymakers in planning health care resources and highlights the urgency of RSV disease prevention.

Authors: Yuan Hai-xia , Wang Changyan , Tang Cong-yu , You Qi-qin , Zhang Qi , Wang Wen-ping 
Published: February 2023

Abstract
Purpose
To verify whether radiomics techniques based on dual-modality ultrasound consisting of B-mode and superb microvascular imaging (SMI) can improve the accuracy of the differentiation between gallbladder neoplastic polyps and cholesterol polyps.

Methods
A total of 100 patients with 100 pathologically proven gallbladder polypoid lesions were enrolled in this retrospective study. Radiomics features on B-mode ultrasound and SMI of each lesion were extracted. Support vector machine was used to classify adenomas and cholesterol polyps of gallbladder for B-mode, SMI and dual-modality ultrasound, respectively, and the classification results were compared among the three groups.

Results
Six, eight and nine features were extracted for each lesion at B-mode ultrasound, SMI and dual-modality ultrasound, respectively. In dual-modality ultrasound model, the area under the receiver operating characteristic curve (AUC), classification accuracy, sensitivity, specificity, and Youden’s index were 0.850 ± 0.090, 0.828 ± 0.097, 0.892 ± 0.144, 0.803 ± 0.149 and 0.695 ± 0.157, respectively. The AUC and Youden’s index of the dual-modality model were higher than those of the B-mode model (p < 0.05). The AUC, accuracy, specificity and Youden’s index of the dual-modality model were higher than those of the SMI model (p < 0.05).

Conclusions
Radiomics analysis of the dual-modality ultrasound composed of B-mode and SMI can improve the accuracy of classification between gallbladder neoplastic polyps and cholesterol polyps.

Published: February 2023

Abstract
Background
Detection of COVID-19 in cancer patients is challenging due to probable preexisting pulmonary infiltration caused by many infectious and non-infectious etiologies. We evaluated chest CT scan findings of COVID-19 pneumonia in cancer patients and explored its prognostic role in mortality.

Methods
We studied 266 COVID-19 patients with a history of cancer diagnosis between 2020 and 2022. Chest CT images were reported based on Radiological Society of North America (RSNA) structural report and the CT score and pattern of involvement were noted. We used multivariate logistic regression models to determine the association between CT scan findings and mortality of the cancer COVID-19 patients.

Results
The mean age was 56.48 (± 18.59), and 53% were men. Gastrointestinal (29.3%), hematologic (26.3%), and breast (10.5%) cancers were the most frequent types of cancer. The prevalence of atypical or indeterminate findings in the chest CT was 42.8%. Most radiologic findings were consolidation mixed with ground-glass opacity (44.4%), pleural effusion (33.5%), and pure ground-glass opacity (19.5%). The risk of death was higher among those who had typical chest CT for COVID-19 (OR 3.47; 95% CI 1.14–8.98) and those who had a severity of score higher than 18 (OR 1.89; 95% CI 1.07–3.34). Also, presence of consolidation (P value 0.040), pleural effusion (P value 0.000), centrilobular nodules (P value 0.013), and architectural distortion (P value 0.005) were associated with a poorer prognosis.

Conclusion
Less than half of COVID-19 patients with a history of cancer had typical imaging features of COVID-19. Radiologists should be aware of atypical, rare, or subtle chest CT findings in patients with pre-existing cancer.
Conradi-Hünerman-Happle Syndrome and Obsessive–Compulsive Disorder: a clinical case report
Authors: de Jesus Sabrina , Costa Ana Lúcia R. , Almeida Mónica , Garrido Paula , Alcafache João 
Published: February 2023

Abstract
Background
Obsessive–Compulsive Disorder (OCD) is a common and chronic psychiatric disorder with significant morbidity characterized by intrusive, uncontrollable and reoccurring thoughts (i.e., obsessions) and/or ritualistic behaviours (i.e., compulsions). Conradi-Hünerman-Happle Syndrome (CHHS) is a rare inherited X-linked dominant variant of chondrodysplasia punctata, a heterogeneous group of rare bone dysplasias characterized by punctate epiphyseal calcifications of complex etiology and pathophysiology that remain to be defined. Available literature reveals a lacuna in regards to the coexistence of the entities with no clinical reports described.

Case presentation
A 12 year old female patient with diagnosis of CHHS, presents to psychiatric consultation due to aggravation of her OCD clinical picture, with aggravation of hand-washing frequency during the Covid-19 pandemic with significant functional impact. Psychopharmacological treatment aimed at OCD with Selective Serotonin Reuptake Inhibitor (SSRI) and antipsychotic was instituted with favourable, albeit partial response.

Conclusions
The authors aim to describe a clinical case in which the patient presents with Conradi-Hünerman-Happle Syndrome and Obsessive–Compulsive Disorder. Clinical descriptions of CHHS and OCD are not available in the literature. Through this case description the authors aim to present a rare case as well as discuss an eventual association between etiology and/or pathophysiology of the two disorders.

Authors: Nan Jiang , Salina Nen , Chong Sheau Tsuey , Jiang Hong-juan 
Published: February 2023

AbstractBackgroundThe aim of this study was to understand the longitudinal trajectory of suicidal ideation (SI) among Chinese medical students and the role of childhood trauma (CT).MethodsUsing a whole-group sampling method, we assessed SI in 2192 (male = 834, female = 1358) medical students on three occasions over a period of one year. The Suicidal Ideation Self-Assessment Scale (SISAS) and the Childhood Trauma Questionnaire-Short Form (CTQ-SF) were used to assess SI and CT. The growth mixture modeling (GMM) was used to classify the developmental trajectory of SI.ResultsA greater number of medical students were experiencing suicidal ideation during the COVID-19 pandemic. The trajectory of SI among medical students was divided into two groups: a low risk, slowly rising group and a high risk, continuous group. The low risk, slowly rising group had a significant time effect (B = 1.57,p < 0.001) and showed a slowly increasing trend. Emotional neglect (EN), physical neglect (PN), emotional abuse (EA) and physical abuse (PA) all had significant positive predictive effects for the high risk, continuous group (B = 0.18–0.65,P < 0.01).ConclusionThe trajectory of SI among medical students can be divided into a low risk, slowly rising group and a high risk, continuous group; the more EN, PN, EA and PA experienced during childhood, the more likely medical students are to develop a high risk, continuous state of SI.

Authors: Hirahata Masahiro , Yasui Youichi , Fujita Muneyoshi , Ishii Keisuke , Kawano Hirotaka , Kitagawa Tomoaki 
Published: February 2023

Abstract
Background
The World Health Organization (WHO) defines a person with a body mass index (BMI) greater than or equal to 25 kg/m2 as overweight. Being overweight is a lifestyle-related disease; however, little is known about the impact of overweight on the perioperative complications of orthopedic surgery. This study aimed to define the effect of overweight on the perioperative complications of spinal surgery.

Methods
This retrospective case series study reviewed 269 consecutive patients who underwent spinal surgery. These patients were divided into the overweight (OW) and non-overweight (NOW) groups. Age, BMI, surgical time, blood loss, and perioperative complications were evaluated and compared between the groups.

Results
There were 117 patients (43%) in the OW group and 152 (57%) in the NOW group. Cervical surgery was performed in 72 cases, thoracic surgery in 34, and lumbosacral surgery in 159. The surgical time was significantly longer in the OW group than in the NOW group (204.6 ± 98 min vs. 175 ± 75 min; p = 0.01). Blood loss was greater in the OW group than in the NOW group (446.8 ± 447.9 mL vs. 279 ± 296.5 mL; p = 0.00). Durotomy was more frequent in the OW group than in the NOW group (10 vs. 3 cases; p = 0.02). There was no difference in complications other than durotomy.

Conclusions
OW patients had longer surgical time, more blood loss, and more frequent durotomy than NOW patients. These findings indicate that overweight increases perioperative complications of spinal surgery.

Abstract
Background
Most medical educational programs emphasize clinical observation or clinical skill acquisition, fewer focus upon research. The Danish-American Research Exchange (DARE) program, sponsored by the Lundbeck Foundation, is unique in that the medical student initiates biomedical research collaboration between Danish and US medical institutions. To achieve this, Danish medical students (DARE students) conduct binational mentored research projects while based in the United States for 10 months. In addition, DARE students are introduced to interdisciplinary thinking about how to develop ultra-low-cost healthcare interventions through the ‘$10 Challenge’.

Methods
We conducted a cross-sectional study of DARE alumni over five consecutive years (2015–2020, n = 24). Research metrics included completion of a research project, primary authorship, and co-authorship of publications. The number of publications, prior to and after the DARE program were enumerated. For the first four cohorts, graduation from medical school and acceptance or intention to enter a joint MD-PhD program also were assessed. Two focus groups were conducted using constructivist grounded theory. Discussions were transcribed, redacted, and coded using Dedoose software.

Results
DARE Medical students were 31.2 years (range 24–35), the majority were women (67%;16/24). The majority (17/24;71%) completed a first author publication in a peer-reviewed journal with a median of 3.9 per DARE alumnus. DARE alumnus reported increased proficiency in biostatistics, epidemiology, coding and public speaking as well as stronger research qualities in creativity, critical thinking, comfort in approaching scientist in both the US and Denmark (p < 0.001 for all). Qualitative key themes included: increased confidence, a deepening of research inquiry and linkage to a research network.

Conclusions
Preliminarily, this study suggests that medical students can initiate binational collaboration in medicine. Benefits include research productivity, intention to pursue academic medical careers, as well as positive impacts on motivation. This medical student-initiated research model lays the groundwork for using this model across other country pairs to promote binational collaboration.
Factors influencing the implementation of decision support systems for antibiotic prescription in hospitals: a systematic review
Authors: Tokgöz Pinar , Hafner Jessica , Dockweiler Christoph 
Published: February 2023

Abstract
Background
Antibiotic resistance is a major health threat. Inappropriate antibiotic use has been shown to be an important determinant of the emergence of antibiotic resistance. Decision support systems for antimicrobial management can support clinicians to optimize antibiotic prescription.

Objective
The aim of this systematic review is to identify factors influencing the implementation of decision support systems for antibiotic prescription in hospitals.

Methods
A systematic search of factors impeding or facilitating successful implementation of decision support systems for antibiotic prescription was performed in January 2022 in the databases PubMed, Web of Science and The Cochrane Library. Only studies were included which comprised decision support systems in hospitals for prescribing antibiotic therapy, published in English with a qualitative, quantitative or mixed-methods study design and between 2011 and 2021. Factors influencing the implementation were identified through text analysis by two reviewers.

Results
A total of 14 publications were identified matching the inclusion criteria. The majority of factors relate to technological and organizational aspects of decision support system implementation. Some factors include the integration of the decision support systems into existing systems, system design, consideration of potential end-users as well as training and support for end-users. In addition, user-related factors, like user attitude towards the system, computer literacy and prior experience with the system seem to be important for successful implementation of decision support systems for antibiotic prescription in hospitals.

Conclusion
The results indicate a broad spectrum of factors of decision support system implementation for antibiotic prescription and contributes to the literature by identifying important organizational as well as user-related factors. Wider organizational dimensions as well as the interaction between user and technology appear important for supporting implementation.
Being well? A meta-ethnography of older patients and their relatives’ descriptions of suffering and well-being in the transition from hospital to home
Authors: Dragosits Aline , Martinsen Bente , Hemingway Ann , Norlyk Annelise 
Published: February 2023

Abstract
Background
As the average length of hospital stay decreases, more and more older patients will need support during and after the hospital transition, which will mainly be provided by their relatives. Studies highlight the enormous effect such a transition has on the lives of older patients and their relatives. However, research is lacking regarding in-depth understanding of the complexities and the notions of suffering and well-being the older patients and their relatives describe in the transition from hospital to home. Therefore, this study aims to examine the description of suffering and well-being on a deeper, existential level by drawing on existing phenomenological research.

Methods
In order to synthesize and reinterpret primary findings, we used the seven-step method for meta-ethnography. Following specific inclusion criteria and focusing on empirical phenomenological studies about older patients and their relatives experiences of hospital to home transitions, a systematic literature search was conducted. Data from ten studies have been analyzed.

Results
Our analysis identified three intertwined themes: i) ‘Being excluded vs. being included in the transition process’, ii) ‘Being a team: a call for support and a call to support’ and iii) ‘Riding an emotional rollercoaster’. The last theme was unfolded by the two subthemes ‘Taking on the new role as a caregiver: oscillating between struggling and accepting’ and ‘Getting back to normal: oscillating between uncertainty and hope’. Within those themes, older patients and their relatives described rather similar than contradictory aspects.

Conclusions
This study offers insights into the tension between existential suffering and well-being described by the older patients and their relatives during the transition from hospital to home. Especially, the description of well-being in all its nuances which, if achieved, enables older patients and their relatives to identify with the situation and to move forward, this process can then be supported by the health care professionals. However, there is still lack of knowledge with regards to a deeper understanding of existential well-being in this process. Given the increasing tendency towards early hospital discharges, the findings underpin the need to further investigate the experiences of well-being in this process.
