Formal grammar methodology for digital visualization of Islamic geometric patterns
Authors: Refalian Ghazal , Coloma Eloi , Moya Joaquim N 
Published: December 2021

In the oriental practice of art and architecture, and among the regions under their influence, Islamic geometric patterns (IGPs) have been widely used, not only due to aesthetics and decoration but also to make it possible to cover wide flat surfaces, curved surface of domes, and perforated surfaces of window and partitions, with perfectly tessellated shapes. However, with advances in time and technology, these techniques could not connect to the new technologies and benefit from the capacities of digitalization. Recent progress in science and technology tends to open new doors to study geometrical patterns by digitalizing the old ones and developing new variations. This study looks at formal grammar and computer science to introduce a new approach to digital visualization of available IGPs, particularly, star patterns. We investigate the potentials of developing a re-writing system for simulation of IGPs to provide a flexible platform, which allows introducing IGP to CAD/CAM software without previous knowledge on their design or drawing techniques. This methodology allows designers to directly develop various scenarios of IGP applications and implement them on related CAD/CAM tools. Formal language and grammar theories, based on applied mathematics are contributing to the advancements of computer science and digital modeling. They can provide an opportunity to express relational definition and written equivalents of the geometries by using strings and symbols. It is supposed that by using the formal grammar frameworks, certain languages could be developed to visualize IGPs in a machine-friendly way, and consequently, this computational interpretation of IGPs facilitates their application and further developments, for example, regards to digital fabrication. The presented method of IGP visualization is developed as a C#-based add-on for Grasshopper in Rhino3D, one of the main modeling tools used by architects and product designers.

Objectives: To study the outcome of endovascular treatment of aortic pathologies in patients with Marfan syndrome (MFS) at a single institution. Methods: Consecutive MFS patients who underwent endovascular repair or hybrid procedures for aortic pathologies from January 2010 to May 2020 were identified. Several endovascular and hybrid strategies have been used. Technical success, short- and mid-term survival, complications, and re-interventions were retrospectively analyzed. Results: During the study period, 24 patients with MFS (median age, 48 [13–78] years; 58% males) were treated. Indications for intervention were chronic aortic dissection with aneurysm degeneration in 16 patients (67%), acute type B aortic dissection in 4 patients (17%), aortic aneurysm without any dissection in 3 patients (13%), and aortic intramural hematoma in 1 patient (4%). Most patients were asymptomatic (83%), three (13%) were symptomatic and one (4%) had a contained rupture. The median aneurysm diameter was 56 (35–86) mm. Hybrid procedures were performed in 7 (29%) patients. Thoracic endovascular repair was performed in 12 (50%) patients, a fenestrated or branched endovascular aortic repair in 4 (17%) patients, and placement of an iliac artery stent-graft in 1 (4%) patient. Procedures were staged in 12 (50%) patients. Technical success was achieved in all patients. The median intensive care unit stay was 6 (range, 1–30) days, and the median hospital stay was 23 (range, 3–112) days. Early mortality was reported in 1 (4%) patient. Wound infection was seen in 7 (29%) patients and gastrointestinal complications in 3 (13%) patients. The median follow-up was 42 (range, 1–127) months. The cumulative survival rate was 87% at 24 months. The cumulative freedom from re-intervention was 77% at 12 months. Conclusions: Endovascular treatment of aortic pathologies in patients with MFS appears feasible with acceptable early and mid-term outcomes in terms of mortality and re-intervention rates. Endovascular therapy plays an increasing role in MFS patients with aortic pathology.

Introduction To compare endoleak outcomes after thoracic endovascular aneurysm repair (TEVAR) with different stent-graft generations into long-term follow-up. Design retrospective, observational, and single-center cohort study. Methods TEVAR procedures performed between November 1995 and December 2020 were analyzed. The primary endpoint of this study was the freedom from endoleak (type I/III) in four stent-graft generations during the follow-up period. The first generation (GEN1) included: Vanguard; AneuRx and Talent; Stentor; Excluder; Endologix; EndoFit. The second generation (GEN2) included: TAG and TX. The third (GEN3) included: Relay Plus; Valiant Captivia; Zenith Alpha and custom-made. The fourth (GEN4) included: Relay Pro; Conformable C-TAG; Navion; E-Vita; Najuta; Nexus; standard and custom-made thoraco-abdominal devices. Nonaortic and aorta-related survival was considered as secondary outcome. Results A total of 509 TEVAR were included with a 44.3 ± 42.5 months mean follow-up. Freedom from endoleak at 5 years was 65.6%, 61.4%, 76.2%, and 69.1% for GEN1, GEN2, GEN3, and GEN4, respectively ( p = 0.368). The first two generations demonstrated a higher endoleak rate when compared with the two most recent ones (27.2 vs 18.2%, respectively; p = 0.043). GEN1 was an independent risk factor ( p = 0.014) and GEN4 was an independent protective factor ( p = 0.001) for endoleak. GEN1 was found to be a risk factor for type-Ia endoleak ( p = 0.059). GEN4 demonstrated a protective association regarding type-Ib endoleak ( p = 0.012). Overall survival was 75.3%, 44.4%, 27.2%, and 17.6% at 1, 5, 10, and 15 years, respectively. Survival distinguished as non-related versus aortic-related was 86.7% vs 23.5%, 52.7% vs 9.8%, 32.9% vs 2.0%, 21.2% vs 0% at 1, 5, 10, and 15 years, respectively ( p< 0.000). Conclusion Endoleak occurred in a non-negligible percentage of TEVAR patients. A significant reduction of endoleak incidence over evolving stent-grafts generations was registered. Newer stent-graft generations demonstrated better long-term endoleak. Data about long-term outcomes require ongoing updates to prove both the reliability and the durability of newer stent-graft generations.

A 76-year-old lady was found on the floor following a fall at home. She was uninjured, but unable to get up, and had been lying on the floor for roughly 18 hours before her son arrived. She had been unwell for the past 3 days with a cough and shortness of breath. She had a past medical history of diabetes, hypertension, hypercholesterolaemia and atrial fibrillation (AF). On examination, she was alert but distressed, clinically dehydrated, febrile and tachycardic. She was treated for community acquired pneumonia with co-amoxiclav and was fluid resuscitated with Hartmann’s solution. Her hyperkalaemia was treated with 50 mL of 50% glucose containing 10 units of rapid-acting insulin. Her creatinine kinase (CK) on admission was 200,000, and she had an acute kidney injury (AKI). Urine dipstick was positive for blood. However, her renal function continued to deteriorate over the succeeding 48 h, when she required renal replacement therapy (RRT) due to fluid overload and anuria.

Abstract
Azacitidine-mediated hypomethylation promotes tumor cell immune recognition but may increase the expression of inhibitory immune checkpoint molecules. We conducted the first randomized phase 2 study of azacitidine plus the immune checkpoint inhibitor durvalumab vs azacitidine monotherapy as first-line treatment for higher-risk myelodysplastic syndromes (HR-MDS). In all, 84 patients received 75 mg/m2 subcutaneous azacitidine (days 1-7 every 4 weeks) combined with 1500 mg intravenous durvalumab on day 1 every 4 weeks (Arm A) for at least 6 cycles or 75 mg/m² subcutaneous azacitidine alone (days 1-7 every 4 weeks) for at least 6 cycles (Arm B). After a median follow-up of 15.25 months, 8 patients in Arm A and 6 in Arm B remained on treatment. Patients in Arm A received a median of 7.9 treatment cycles and those in Arm B received a median of 7.0 treatment cycles with 73.7% and 65.9%, respectively, completing ≥4 cycles. The overall response rate (primary end point) was 61.9% in Arm A (26 of 42) and 47.6% in Arm B (20 of 42; P = .18), and median overall survival was 11.6 months (95% confidence interval, 9.5 months to not evaluable) vs 16.7 months (95% confidence interval, 9.8-23.5 months; P = .74). Durvalumab-related adverse events (AEs) were reported by 71.1% of patients; azacitidine-related AEs were reported by 82% (Arm A) and 81% (Arm B). Grade 3 or 4 hematologic AEs were reported in 89.5% (Arm A) vs 68.3% (Arm B) of patients. Patients with TP53 mutations tended to have a worse response than patients without these mutations. Azacitidine increased programmed cell death ligand 1 (PD-L1 [CD274]) surface expression on bone marrow granulocytes and monocytes, but not blasts, in both arms. In summary, combining azacitidine with durvalumab in patients with HR-MDS was feasible but with more toxicities and without significant improvement in clinical outcomes over azacitidine alone. This trial was registered at www.clinicaltrials.gov as #NCT02775903.
Swiss GPs’ preferences for antidepressant treatment in mild depression: vignette-based quantitative analysis
Authors: Hengartner Michael P. , Neuner-Jehle Stefan , Senn Oliver 
Published: December 2021

Abstract
Background
GPs frequently prescribe antidepressants in mild depression. The aim of this study was to examine, how often Swiss GPs recommend antidepressants in various clinical presentations of mild depression and which factors contribute to antidepressant treatment recommendations.

Methods
We conducted an online survey among Swiss GPs with within-subject effect analysis. Alternating case vignettes described a typical female case of mild depression according to International Classification of Diseases, 10th edition criteria, with and without anxiety symptoms and sleep problems. GPs indicated for each vignette their preferred treatments (several recommendations were possible). Additionally, we assessed GP characteristics, attitudes towards depression treatments, and elements of clinical decision-making.

Results
Altogether 178 GPs completed the survey. In the initial description of a case with mild depression, 11% (95%-CI: 7%-17%) of GPs recommended antidepressants. If anxiety symptoms were added to the same case, 29% (23%-36%) recommended antidepressants. If sleep problems were mentioned, 47% (40%-55%) recommended antidepressants, and if both sleep problems and anxiety symptoms were mentioned, 63% (56%-70%) recommended antidepressants. Several factors were independently associated with increased odds of recommending antidepressants, specifically more years of practical experience, an advanced training in psychosomatic and psychosocial medicine, self-dispensation, and a higher perceived effectiveness of antidepressants. By contrast, a higher perceived influence of patient characteristics and the use of clinical practice guidelines were associated with reduced odds of recommending antidepressants.

Conclusions
Consistent with depression practice guidelines, Swiss GPs rarely recommended antidepressants in mild depression if no co-indications (i.e., sleep problems and anxiety symptoms) were depicted. However, presence of sleep problems and anxiety symptoms, many years of practical experience, overestimation of antidepressants’ effectiveness, self-dispensation, an advanced training in psychosomatic and psychosocial medicine, and non-use of clinical practice guidelines may independently lead to antidepressant over-prescribing.

Abstract
Background
The majority of breast cancer patients are severely psychologically affected by breast cancer diagnosis and subsequent therapeutic procedures. The COVID-19 pandemic and associated restrictions on public life have additionally caused significant psychological distress for much of the population. It is therefore plausible that breast cancer patients might be particularly susceptible to the additional psychological stress caused by the pandemic, increasing suffering. In this study we therefore aimed to assess the level of psychological distress currently experienced by a defined group of breast cancer patients in our breast cancer centre, compared to distress levels pre-COVID-19 pandemic.

Methods
Female breast cancer patients of all ages receiving either adjuvant, neoadjuvant, or palliative therapies were recruited for the study. All patients were screened for current or previous COVID-19 infection. The participants completed a self-designed COVID-19 pandemic questionnaire, the Stress and Coping Inventory (SCI), the National Comprehensive Cancer Network® (NCCN®) Distress Thermometer (DT), the European Organization for Research and Treatment of Cancer (EORTC) QLQ C30, and the BR23.

Results
Eighty-two breast cancer patients were included. Therapy status and social demographic factors did not have a significant effect on the distress caused by the COVID-19 pandemic. The results of the DT pre and during COVID-19 pandemic did not differ significantly. Using the self-designed COVID-19 pandemic questionnaire, we detected three distinct subgroups demonstrating different levels of concerns in relation to SARS-CoV-2. The subgroup with the highest levels of concern reported significantly decreased life quality, related parameters and symptoms.

Conclusions
This monocentric study demonstrated that the COVID-19 pandemic significantly affected psychological health in a subpopulation of breast cancer patients. The application of a self-created “COVID-19 pandemic questionnaire” could potentially be used to help identify breast cancer patients who are susceptible to increased psychological distress due to the COVID-19 pandemic, and therefore may need additional intensive psychological support.

Published: December 2021

Abstract
Background
The use of digital interventions for managing chronic diseases is significantly increasing. The aim of this study was to estimate the proportion of ownership of a mobile phone, and factors associated with the ability to read and access SMS delivered health information, and willingness to pay for it among people with hypertension in a rural area in Bangladesh.

Methods
Data were collected from 307 participants aged 30 to 75 years with hypertension from a rural area in Bangladesh from December 2020 to January 2021. Outcome measures included ownership of a mobile phone, ability to read SMS, willingness to receive and pay for health information by SMS. Associated factors included age, gender, level of education, occupation, and socioeconomic status. We used regression analysis to identify variables associated with the outcome variables.

Results
Overall, 189 (61.6%) people owned a mobile phone which was higher in men (73.3% vs. 50%, p < 0.001), younger people (82.6% aged 30–39 years vs. 53.5% aged 60–75 years, p < 0.001). Of the total participants, 207 (67.4%) were willing to receive SMS, and 155 (50.5%) were willing to pay for receiving SMS for health information. The prevalence was significantly higher among professionals (odds ratio (OR), 95% confidence interval (CI): 4.58, 1.73–12.1) and businesspersons (OR 3.68, 95% CI 1.49–9.10) compared to farmers, respectively. The median (interquartile range [IQR]) of willingness to pay for health information SMS was 10 (28) Bangladesh Taka (BDT) (1 BDT ~ 0.013 US$), and there were no specific factors that were associated with the willingness of any higher amounts of payment. In terms of reading SMS of people who own a mobile, less than half could read SMS. The proportion of people who could read SMS was significantly higher among men, younger people, educated people, middle class or rich people, professionals or businesspersons. Of people who could read SMS, the majority read SMS occasionally.

Conclusion
A significant proportion of people are unable to read SMS. However, people are willing to receive and pay to receive SMS for health information. Education and awareness programs should be conducted among targeted groups, including people with low education and women.

Abstract
Background
Dual antiplatelet therapy (DAPT) in patients with MI who are candidates for early coronary artery bypass grafting (CABG) can affect intraoperative and postoperative outcomes. Therefore, the aim of this study was to evaluate the effect of DAPT up to the day before CABG on the outcomes during and after surgery in patients with MI.

Methods
In this prospective cohort study, 224 CABG candidate patients with and without MI were divided into two groups: (A) patients without MI who were treated with aspirin 80 mg/day before surgery (noMI-aspirin group; n = 124) and (B) patients with MI who were treated with aspirin 80 mg/day before surgery and clopidogrel (Plavix brand) at a dose of 75 mg/day (MI-DAPT group; n = 120). Dual or mono-antiplatelet therapy continued until the day before surgery. Patients were followed to assess in-hospital and 6-months outcomes.

Results
The in-hospital mortality in MI-DAPT group was similar with noMI-aspirin group (OR 4.2; 95% CI 0.9–20.5; p = 0.071). The prevalence of CVA (p = 0.098), duration of hospital stay (p = 0.109), postoperative ejection fraction level (p = 0.693), diastolic dysfunction grade (p = 0.651) and postoperative PAP level (p = 0.0364) did not show difference between two groups. No mild or severe bleeding was observed in the patients. Six-month follow up showed that number of readmissions (p = 0.801), number of cases requiring angiography (p = 0.100), cases requiring re-PCI (p = 0.156), need for re-CABG (p > 0.999) and CVA (p > 0.999) did not differ between the two groups. During the 6-month follow-up, out-hospital mortality did not differ significantly between the two groups (p = 0.446).

Conclusions
A 6-month follow-up showed that DAPT with aspirin and clopidogrel before CABG in patients with MI has no effect on postoperative outcomes more than mono-APT with aspirin. Therefore, DAPT is recommended in the preoperative period for these patients.
Comparison of nephroscopy and cystoscopy used in the treatment of bladder stones: a systematic review and meta-analysis of randomized controlled trials
Authors: Gou Liping , Wang Zhenghao , Zhou Ye , Zheng Xiaofeng 
Published: December 2021

Abstract
Background
A systematic review and meta-analysis was conducted to compare the safety and efficiency of nephroscopy and cystoscopy in transurethral cystolithotripsy (TUCL) for bladder stones (BS).

Methods
The PubMed, Web of Science, Embase, EBSCO, and Cochrane Library databases were searched up to January 2021 for studies assessing the effect of different types of endoscopes among patients who underwent TUCL. The search strategy and study selection process were in accordance with the PRISMA statement.

Results

Five randomized controlled trials were included in the meta-analysis. The results showed no difference in stone-free rate (RR = 1.00, CI = 0.98–1.02, p = 1.00) between the two groups and nonsignificant heterogeneity (I2 = 0%, p = 1.00), and all patients were rendered stone free. Use of the nephroscope significantly shortened the operative time compared with the cystoscope group (RR= − 26.26, CI = − 35.84 to − 16.68, p < 0.00001), and there was significant heterogeneity (I2= 87%, p < 0.00001). There was no significant difference in mean urethral entries (RR = 0.66, CI = − 0.71 to − 2.04, p = 0.35), hospitalization (MD = 0.08, 95% CI = − 0.07 to 0.23, p = 0.31) or total complication rate (RR=1.37, 95% CI = 0.47–4.00, p = 0.56) between the two groups.

Conclusions
In conclusion, this systematic review demonstrates that both nephroscopy and cystoscopy have high stone clearance efficiency, low rates of complications and short hospitalizations. The mean urethral entries depend on the treatment method for large stone fragments. However, the use of nephroscopy can significantly reduce the operative time.
