Authors: Ngo Duy Q. , Le Duong T. , Hoang Giap N. , Ngo Quy X. , Le Quang V. 
Published: October 2021

Background: Transoral endoscopic thyroidectomy via vestibular approach (TOETVA) is a new technique that has become more popular worldwide because of its many advantages. However, this novel approach for thyroid cancer treatment in children is highly challenging, even for high-volume surgeons. In our study, we report our experiences with TOETVA for pediatric patients with thyroid cancer.Patients and Methods: This study included four pediatric patients who underwent TOETVA performed by a single surgeon between June and December 2020. Patient demographics and surgical outcomes including operative time, incidence of complications, and length of hospital stay were evaluated.Results: Four patients successfully underwent TOETVA with no complications. All patients were girls, aged from 13 to 18. Three patients underwent lobectomy and isthmusectomy, plus prophylactic unilateral central neck dissection. One patient had a total thyroidectomy, plus prophylactic bilateral central neck dissection. The mean operative time was 85 min for the lobectomy and 120 min for total thyroidectomy plus central neck dissection. The median hospital stay was 4.1 days. No drains were used. The histological examination showed four cases of malignant disease (papillary thyroid carcinoma). The mean number of harvested lymph nodes was 4.2 (ranged 3 to 8).Conclusion: In the hands of a high-volume surgeon, TOETVA is a novel, feasible, and safe approach for treating selected pediatric patients with thyroid cancer.

Published: October 2021

Background: The symptoms of attention-deficit hyperactivity disorder (ADHD) are known to exacerbate the effect of cognitive-behavioral impairments on emotional burden. Although adults with ADHD frequently experience procrastination and internalizing symptoms such as depression and anxiety, few studies have examined whether the association between procrastination and internalizing symptoms differs by ADHD symptoms.Objective: This study aimed to examine the moderating effect of ADHD symptoms on the association between procrastination and internalizing symptoms.Method: A cross-sectional survey was conducted among 470 adults (mean age=26.57, standard deviation=2.93) using self-reported questionnaires: Adult ADHD Self-Report Scale, General Procrastination Scales, Patient Health Questionnaire-9, and State–Trait Anxiety Inventory.Conclusion: Participants with more substantial ADHD symptoms experienced more procrastination and internalizing symptoms than those with the less substantial ADHD symptoms. Therefore, procrastination constitutes the treatment target for those suffering from ADHD and comorbid internalizing symptoms. Alternatively, there was no enhancing effect of ADHD symptoms on the association between procrastination and internalizing symptoms. It is necessary to examine more precise and valid hypotheses and underlying mechanisms of procrastination in high and low ADHD symptom groups.
The Behavioral Sequelae of Cannabis Use in Healthy People: A Systematic Review
Authors: Sorkhou Maryam , Bedder Rachel H. , George Tony P. 
Published: October 2021

Background: Cannabis is known to have a broad range of effects on behavior, including experiencing a “high” and tranquility/relaxation. However, there are several adverse behavioral sequalae that can arise from cannabis use, depending on frequency of use, potency (e.g., THC content), age of onset, and cumulative exposure. This systematic review examined evidence for cannabis-related adverse behavioral sequalae in otherwise healthy human subjects.Methods: Following PRISMA guidelines, we conducted a systematic review of cross-sectional and longitudinal studies from 1990 to 2020 that identified cannabis-related adverse behavioral outcomes in subjects without psychiatric and medical co-morbidities from PubMed and PsychInfo searches. Key search terms included “cannabis” OR “tetrahydrocannabinol” OR “cannabidiol” OR “marijuana” AND “anxiety” OR “depression” OR “psychosis” OR “schizophrenia” “OR “IQ” OR “memory” OR “attention” OR “impulsivity” OR “cognition” OR “education” OR “occupation”.Results: Our search detected a total of 2,870 studies, from which we extracted 124 relevant studies from the literature on cannabis effects in the non-clinical population. Effects of cannabis on several behavioral sequelae including cognition, motivation, impulsivity, mood, anxiety, psychosis intelligence, and psychosocial functioning were identified. The preponderance of the evidence suggests that frequency of cannabis use, THC (but not CBD) content, age of onset, and cumulative cannabis exposure can all contribute to these adverse outcomes in individuals without a pre-existing medical condition or psychiatric disorder. The strongest evidence for the negative effects of cannabis are for psychosis and psychosocial functioning.Conclusions: Although more research is needed to determine risk factors for development of adverse behavioral sequelae of cannabis use, these findings underline the importance of understanding vulnerability to the adverse effects of cannabis, which has implications for prevention and treatment of problematic cannabis use.

Objectives: To explore and understand the SARS-CoV-2 seroprevalence of convalescents, the association between antibody levels and demographic factors, and the seroepidemiology of convalescents of COVID-19 till March 2021.Methods: We recruited 517 voluntary COVID-19 convalescents in Sichuan Province and collected 1,707 serum samples till March 2021. Then we reported the seroprevalence and analyzed the associated factors.Results: Recent travel history was associated with IgM levels. Convalescents who had recent travel history were less likely to be IgM antibody negative [OR = 0.232, 95% CI: (0.128, 0.420)]. Asymptomatic cases had, approximately, twice the odds of being IgM antibody negative compared with symptomatic cases [OR = 2.583, 95% CI: (1.554, 4.293)]. Participants without symptoms were less likely to be IgG seronegative than those with symptoms [OR = 0.511, 95% CI: (0.293, 0.891)]. Convalescents aged 40–59 were less likely to be IgG seronegative than those aged below 20 [OR = 0.364, 95% CI: (0.138, 0.959)]. The duration of positive IgM antibodies persisted 365 days while the IgG persisted more than 399 days.Conclusions: Our findings suggested that recent travel history might be associated with the antibody levels of IgM, while age could be associated with the antibody levels of IgG. Infection type could be associated with both antibody levels of IgM and IgG that declined quicker in asymptomatic cases.

Published: October 2021

Objectives: The objective of this study was to determine the identification rate of substandard and falsified medications and its association with knowledge among public.Methods: This descriptive cross-sectional study was conducted in different geographic areas among a convenient sample of people aged 18 or older. A validated web-based electronic questionnaire was used for data collection tool. The questionnaire contained three sections assessing the following: (1) Sociodemographic data; (2) Knowledge regarding counterfeit medicines; and (3) Ability to identify counterfeit medicines, according to 12 questions rated on a five-point Likert scale. Univariate and multivariate logistic regression analyses were used to assess the association between sociodemographic factors and counterfeit medication identification rate.Results: A total of 320 people participated in the study. Only 98 participants (30.6%, 95% CI 25.6–35.7%) identified the counterfeit medications. Ability to correctly identify counterfeit medications was significantly higher in participants who were older (p = 0.016), single (p = 0.001), Asian (p = 0.001), or American (p = 0.019), as well as those who indicated that they would check the certification of the medications (p = 0.015) and report counterfeit medications to the authorities (p &lt; 0.0001).Conclusions: These results underscore the need for greater public awareness of the hazards associated with counterfeit medicines.
The professional resilience of mid-career GPs in the UK: a qualitative study
Authors: Martin Lucy , McDowall Almuth 
Published: October 2021

BackgroundWith a continued crisis of increasing workload and reduced workforce in general practice, supporting resilience is a key strategy for sustaining the profession into the future.AimHow do GPs perceive professional resilience, and what workplace factors influence it?Design and settingA UK-based qualitative study of the perspectives of GPs currently practicing in mainly urban locations across the UK with ≥5 years’ experience after completion of GP training.MethodParticipants were recruited using convenience sampling, which included social media forums, and underwent semi-structured interviews undertaken in May and June 2020 (n= 27). Data were analysed using thematic analysis.ResultsParticipants offered definitions of and influences on resilience that largely fit with existing research, but in addition, may result in the perception that GPs are obstructive, or that resilience may be a ‘surface act’. GPs agree that the current focus on methods of improving resilience does support them, but there is significantly more to be done in this field. Social media activity aiming at GP support may be counterproductive. Reduction of clinical working hours is a common strategy to improve resilience.ConclusionThat GPs feel to improve resilience they need to work fewer clinical hours may have huge implications for a workforce already in crisis, and ultimately, for the health care of the UK population. Urgent research is needed to formulate a bespoke assessment for measuring GP resilience to assess potential interventions, and to identify GPs at risk of mental ill-health or leaving the profession.

Purpose. The study aimed at the comparison of computed tomography (СT) contrast enhancement (CE) protocols for optimal visualization of cardiac chambers, evaluation of their impact on results of non-invasive superficial cardiac mapping.Methods. The study included 93 patients with heart rhythm disorders in whom catheter ablation of arrhythmia was planned. Noninvasive cardiac mapping for arrhythmia localization was performed and included multichannel ECG-registration and CT with intravenous СE (1st group - monophasic (50 patients), 2nd group - split-bolus (18 patients), 3rd group - with pre-bolus (25 patients). Qualitative and quantitative (measurement of mean blood attenuation in four chambers, calculation of ventricular-myocardial [VM] contrast-to-noise ratio VM-LV и VM-RV for the left ventricle [LV] and right ventricle [RV], respectively) parameters were compared between the groups. Fusion of ECG and CT data was carried out a semi-automatic mode with a non-invasive imaging complex.Results. Regardless of CE technique, sufficient and homogeneous contrast attenuation was obtained for the left atrium (LA) and LV (mean blood attenuation in LA more than 278 HU, LV 250 HU, VM-LV 0,582). In most cases, the enhancement of the right heart was insufficient with the monophasic protocol; the average CT density was lower than 200 HU, VM-RV 0,256. The split-bolus protocol improved visualization of the right atrium (RA) and RV (blood density in RA 258HU, RV 227HU, VMRV 0,541); however, there was a heterogeneity of the RA cavity due to artifacts from the superior vena cava (VC) and unenhanced blood from the inferior VC. Pre-bolus administration increased the contrast ratio between RA myocardium and blood due to the improvement of blood CT density in the inferior VC (blood density 294 HU). The quality of RV CE was similar to 2nd group (blood density 264 HU, VM-RV 0,565).Conclusion. The split-bolus and with pre-bolus CE protocols improve visualization of the RV, supporting the high-level enhancement of the left heart. The protocol with a pre-bolus is preferable for exact differentiation of the right atrial endocardial contour.

Published: October 2021

INTISARI Perkembangan teknologi pendidikan di Jawa Tengah kususnya di daerah purworejo berkembang dengan pesat. SMK VIP Purworejo saat ini menggunakan sistem informasi penjadwalan berbasis web. Jumlah mata pelajaran yang banyak dan sering berubah sewaktu-waktu sering menimbulkan masalah. Banyaknya jumlah mata pelajaran dan guru yang mengajar maka akan semakin membutuhkan waktu yang lama untuk mengetahui mata pelajaran yang diampu oleh guru tersebut dan untuk mengetahui jam mengajar. View merupakan virtual table dimana isinya (kolom dan baris) didefinisikan dari satu query yang dapat melibatkan beberapa tabel sekaligus. Tujuan dari pembuatan view adalah untuk kenyamanan (mempermudah penulisan query), untuk keamanan (menyembunyikan beberapa kolom yang bersifat rahasia), atau bisa digunakan untuk mempercepat proses menampilkan data (terutama jika kita akan menjalankan query tersebut secara berulang). Eksekusi query basisdata membutuhkan response time. Apabila query yang dieksekusi membutuhkan response time yang lama, maka performansi basisdata berkurang. Salah satu cara untuk meningkatkan performansi basisdata adalah dengan menerapkan view.Tujuan dari penelitian ini adalah untuk mengetahui efisiensi sintak dan performa kecepatan dengan menggunakan query join dan view.Kata Kunci— Database, Optimasi query, view ABSTRACT The development of education technology in Central Java kususnya in the region purworejo growing rapidly. SMK VIP Purworejo currently uses web-based scheduling information system. The number of subjects that are overwhelming and often changing at times often creates problems. The large number of subjects and teachers who teach it will take a long time to find out the subjects being taught by the teacher and to know the hours of teaching. View is a virtual table where the contents (columns and rows) are defined from a single query that can involve multiple tables at once. The purpose of view creation is for convenience (ease of writing queries), for security (hiding some secret columns), or can be used to speed up the process of displaying data (especially if we will run the query repeatedly). Database query execution requires response time. If the query that is executed requires a long response time, then the performance of the database is reduced. One way to improve database performance is by applying view. The purpose of this research is to know the efficiency of syntax and speed performance by using join and view query.Keywords- Database, query optimization, view
