Authors: Van Nooten G. , Van Belleghem Y. , Foubert L , François K. , Caes F. , Van Overbeke H. , Taeymans Y.
Published: September 2022

Objective

The aim of the study is to explore the feasibility and mid-term patency of an easier anastomotic technique for Minimally Invasive Direct Coronary Bypass Grafting (MIDCAB).

Methods

Eight mongrel dogs (±15 kg) underwent direct anastomosis between the left internal thoracic artery (LITA) and the left anterior descending coronary artery (LAD) via inferior sternotomy on the beating heart. After positioning the graft, the distal part of the LAD was opened to allow retrograde filling of the LITA-graft. The anastomosis was secured by the use of biological glue (BtoGlue, Cryolife, Marietta, GA, USA). No intravascular suture material was used. Ischemic time averaged 6 min. The proximal LAD was occluded upstream the arteriotomy. All survivors were angiographically controlled for patency after 6–8 weeks. Consequently, four dogs were sacrificed after 6 weeks and the remaining after 3 months for anatomo-pathological and histological examination by light and electron microscopy of the anastomotic site.

Results

All procedures were successful except for one animal that died of uncontrollable bleeding at the anastomotic site. Another sustained post-operative transmural anterior myocardial infarction due to a late graft occlusion. All angiographically controlled grafts were patent with two vascular strings near the anastomotic site. Histology showed early macrophage infiltration into the glue. At post-mortem examination, new endothelialization was noticed in 80% of the cases. However, ultrastructural examination detected marked differences in endothelial fibroblastic lining compared to normal histology.

Conclusions

Good mid-term permeability of the LITA grafts was observed in this new anastomotic technique for MIDCAB in the canine model. Although neo-endothelialization was present in most cases, ultrastructural differences were noticed after 3 months in the neointima compared to normal.

Published: September 2022

The purpose of this study is to evaluate the efficacy and the safety of carotid endarterectomy (CEA) in the octogenarian patient. From January 1995 to December 2000, we have performed 3430 CEAs in 2743 patients: 345 CEAs in 269 octogenarian patients (Group 1) and 3085 CEAs in 2474 younger patients (Group 2). Age was the only selection criteria for including patients in Group 1. Octogenarians' perioperative mortality (1.4%) was greater than that in Group 2 (0.3%) ( p < 0.05). No differences can be found between the groups' perioperative ipsilateral stroke rates (1.7% in Group 1 vs 1.2% in Group 2) and combined ipsilateral stroke and death rates (2.3% in Group 1 vs 1.3% in Group 2) ( p > 0.05). The octogenarians' Kaplan—Meier 6-year overall and free-stroke survival rates were 86 and 76% respectively. CEA can be performed in selected octogenarian patients with low early and late mortality and neurologic morbidity rates.

Published: September 2022

We report on 215 consecutive patients with isolated aortic replacement of which 91 received an Intact Medtronic (IM) prosthesis and 124 a Carpentier Edwards SAV. (CE). More than 50% of patients were over 70 years old. Follow-up was complete for 95% of patients. Mean follow-up was 6.04 years (16 days–13 years); a total of 1244 patient—years (IM 6.61 years, 590 patient—years, CE 5.95 years. 670 patient—years).

Results:

the following results are expressed for IM and CE groups respectively. Early mortality: 3.3% and 8.13%. Late mortality: 23 and 27 patients. Survival at 13 years: 53.31 ± 7.63% and 47.47 ± 7.9%. Major thromboembolism: 0.34% and 0.30% per patient-year. SVD: 0.16% and 0.14% per patient—year. Endocarditis: 0.33% and 0.29%. Re-operation: 0.5% and 0.44%. Over 95% of patients are re-operation free at 13 years.

Conclusion:

Intact and Carpentier valves had similar durability and clinical/hemodynamic results. Both have proved excellent aortic valve substitutes in elderly patients.
Do Surface Modifying Additives (SMA) Influence Blood Loss and Thrombogenicity in Conventional Cardiopulmonary Bypass for Coronary Artery Bypass Grafting?
Authors: Martens S. , Matheis G. , Wimmer-Greinecker G. , Scherer M. , Doss M. , Moritz A.
Published: September 2022

Cardiopulmonary bypass (CPB) leads to activation of the coagulation and fibrinolytic cascades, partially associated with foreign surface contact. Hemorrhage and the need for blood products is associated with rising cost and increased risk of infection. Treatment with surface modifying additives (SMA) has been shown to reduce thrombogenicity and improve biocompatibility. 76 elective CABG-patients were randomly assigned to surface modifying additives (group I, n = 39) or untreated circuits that were otherwise identical (group II, n = 37). Measurements of coagulation activity and fibrinolysis, platelet count and function were made. The postoperative blood loss and blood product replacement was also assessed. Thrombin formation measured by prothrombin fragments 1 + 2 (5.7±0.4 nmol/l vs. 5.6±0.4 nmol/l), fibrinolytic activity measured by plasmin-antiplasmin complex (1752.6±216.8 μg/l vs.1180.0±74.8 μg/l) and the postoperative platelet count and function did not differ significantly between the two groups. Blood loss and transfusion requirements were slightly lower in the SMA group. The treatment of extracorporeal surfaces with surface modifying additives does not appear to reduce coagulation disorders and bleeding after conventional CPB.
Aortoventriculoplasty in a Patient with Complex Left Ventricular Outflow Tract Obstruction, Mitral Valve Stenosis and Aneurysm of the Ascending Aorta

Published: September 2022

We describe a new method of aortoventriculoplasty in a patient with calcified mitral stenosis, aortic valvular stenosis, severe left ventricular outflow tract obstruction, and aneurysm of the ascending aorta. This complex pathology was successfully treated with replacement of both the valves and a tubular dacron graft. The proximal end of the dacron tube was tailored as a patch for the repair of the ventricular septum and the aortic root, and the distal end was anastomosed to the distal ascending aorta. The patient had an uneventful recovery and postoperative echocardiography showed no significant residual gradient on the left ventricular outflow tract.
An Investigation of the Variables Associated with Normal and Delayed Hospital Discharge following First Time Isolated Coronary Artery Bypass Graft Surgery
Authors: Cox M. G.
Published: September 2022

The optimum day for discharge after coronary artery bypass graft (CABG) surgery has been subject to some debate yet there has been a steady increase in the number of patients discharged within 5 days of surgery. Delayed discharges may result in the under use of surgical capacity and impact upon patient outcomes.

The author conducted a retrospective; correlational study of 333 patients to investigate the variables associated with delayed discharge after CABG. The results suggest it is possible to identify patients likely to achieve a 5-day discharge from their age and Parsonnet score [ Circulation, 79(Suppl. I), 1989, 3.]. The introduction of a policy of adopting a 5-day discharge for those patients could maximise surgical capacity and improve patient outcomes. Further prospective study is recommended after the policy has been implemented to evaluate the effectiveness of age and Parsonnet score to predict a 5-day discharge.

Published: September 2022

From October 1978 to December 1989, 51 patients underwent lower-limb revascularization from the supracoeliac aorta through a transcrural approach. Symptoms were related to lower-limb ischaemia in all patients: 20 had critical ischaemia (three with severe acute ischaemia) and 31 claudication. One patient had renal failure with hypertension and stenosis of the renal arteries associated with an infrarenal aneurysm induced by Takayasu's disease. Indications for exposure of the supracoeliac aorta were Takayasu's disease in two patients and atheroma in 34 (implantation of the graft on the supracoeliac aorta because of the status of the aortic wall (calcification, inflammation) in 25 and because antegrade revascularization of the visceral arteries was required in nine). In 15 patients repeat aortic surgery was performed; four of these had undergone three previous aortic approaches. The postoperative mortality rate at 30 days was 2%. There were four (8%) acute postoperative graft occlusions and four late occlusions, which occurred between 13 months and 6 years. Life-table analysis showed a 5-year primary patency rate(s.d.) of 83(10)% and a 5-year secondary patency rate(s.d.) of 88(8)%. There are few indications for the transcrural approach to the supracoeliac aorta. Nevertheless, this technique can prove useful in selected cases, for example in those with a calcified aorta, for repeat aortic surgery and for aortic thrombosis near the renal arteries. It is also useful when combined revascularization of the lower limb and right renal or hepatic artery is being considered.
Mycotic Aneurysm of the Abdominal Aorta: Extra-Anatomic versus in Situ Reconstruction
Authors: Pasic M. , Carrel T. , Tönz M. , Vogt P. , von Segesser L. , Turina M.
Published: September 2022

Between 1973 and 1991, 12 patients with mycotic aneurysm of the abdominal aorta underwent operation. There were four elective and eight emergency procedures. In situ reconstruction was performed in six patients and extra-anatomic reconstruction with axillobifemoral bypass grafting in six. The hospital mortality rate was 25% (three patients) and another three died during the follow-up period of mean 5.5 years. Descending aorta-bifemoral bypass was performed in two patients without signs of chronic local infection 1 and 2 years after previous axillobifemoral bypass. Late complications were peripheral embolization in one patient after in situ reconstruction and a total of five thromboses of the axillofemoral bypass in three patients. Extra-anatomic bypass grafting remains the method of choice for the majority of patients with mycotic aneurysm of the abdominal aorta. In situ reconstruction seems to be an appropriate procedure for a highly selected group of patients.

Authors: Perler B. A.
Published: September 2022

Over a period of 8 years, 31 femoral pseudoaneurysms following cardiac catheterization were surgically repaired in 15 men and 15 women ranging in age from 38 to 89 (mean 68.1) years. The catheterizations were performed for evaluation of coronary artery disease in 23 patients (77%), valvular heart disease in three (10%), both coronary artery disease and valvular disease in two (7%) and for other reasons in two (7%). Percutaneous transluminal coronary angioplasty was performed in eight patients (27%) and aortic valvuloplasty in one (3%). Surgical repair was performed from 1 to 47 (mean 10.2) days after catheterization under local anesthesia in 16 patients (52%). regional anesthesia in ten (32%) and general anesthesia in five (16%). All lesions were repaired by primary suture. The operating time ranged from 25 to 90 (mean 50.5) min and intraoperative blood loss from 50 to 900 (mean 259.2) ml. There were no operative deaths and one postoperative myocardial infarction. No patients have developed recurrent pseudoaneurysm, with follow-up ranging from 1 to 53 (mean 11.4) months. These results demonstrate that the surgical repair of femoral pseudoaneurysm following cardiac catheterization is safe, effective and durable.

Published: September 2022

The case of a 48-year-old man with an aneurysm of the inferior mesenteric artery is described. This aneurysm was associated with extensive vascular disease characterized by multiple sites of stenosis and occlusion in addition to an upper abdominal aortic aneurysm. Repair of both aneurysms and reconstruction of the left renal artery and inferior mesenteric artery, which supplied all splanchnic circulation, were performed. The aetiology of the disease was thought to involve Takayasu's arteritis.

Authors: Chiba Y. , Muraoka R. , Ihaya A. , Morioka K. , Sasaki M. , Uesaka T.
Published: September 2022

This study evaluated the effects of leucocyte depletion on reperfusion injury during cardiopulmonary bypass in 26 patients who underwent coronary artery bypass graft. In 10 patients leucocytes were continuously separated from the circulating blood; in 16 leucocytes were undepleted. Leucocyte count and serum creatine phosphokinase activity (and that of its isoenzymes) were measured before and after aortic cross-clamping; in addition the cardiac index and required catecholamine dosage during the early postoperative period in the two patient groups were compared. Mean(s.d.) leucocyte counts immediately after surgery were 8622(2887) μl−1 in patients who were leucocyte depleted and 12175(5303) μl−1 in controls ( P < 0.05). Mean(s.d.) creatine phosphokinase activity in patients with leucocyte depletion was significantly lower than in controls (334(121) versus 821(356) units l−1; P < 0.05) immediately after surgery. Moreover, mean(s.d.) catecholamine dosage was significantly less in the leucocyte-depleted group than in controls (1.1(1.9) versus 4.9(2.2)μg kg−1 min−1; P< 0.05). whereas the cardiac index was significantly higher (3.3(0.5) versus 2.3(0.4) I min−1 m−2; P < 0.05). These results suggest that, in the clinical setting, leucocyte depletion during cardiopulmonary bypass provides effective protection against reperfusion injury.

Published: September 2022

Between 1961 and 1991, 23 patients (eight men and 15 women, with a mean age of 50 (range 25-72) years) with cardiac myxomas were managed at the Alfred Hospital, Prahran, victoria, Australia. Symptoms of mitral valve obstruction were present in 13 patients and of systemic embolism in nine. In the patients, 21 myxomas were confined to the left atrium. In the other two patients, one myxoma was confined to the right atrium and the other was a dumb-bell-shaped biatrial myxoma. Most tumours were diagnosed with echocardiography. Removal was achieved via a median sternotomy and by entering the involved chamber. Those myxomas presenting with systemic embolism were always soft and friable, whereas those with obstructive symptoms were large and of variable consistency. There was one operative death early in the series. The 22 surviving patients have been assessed as functional class 1 of the New York Heart Association at follow-up. ranging from 2 months to 23 years (mean 9 years). There were no episodes of tumour recurrence. Excellent short, intermediate and long-term results can be achieved by excision of cardiac myxomas.
Beneficial Effects of β-adrenergic Blockade in Coronary Artery Surgery: Clinical Research
Authors: Yorulmaz F. M. , Kuralay E. , Tatar H. , Süer H. , Öztürk Ö. Y.
Published: September 2022

In an attempt to resolve the controversy concerning use of β-adrenoceptor blockade in patients undergoing coronary artery revascularization, 40 consecutive patients with ischaemic heart disease receiving chronic β-adrenergic blocking therapy (study group) were entered into a randomized trial and were compared with 40 patients receiving no β-blocking therapy (control group). The postoperative requirement for positive inotropic agents between the two groups was compared. The clinical and operative characteristics of the two groups were similar. After surgery, 2% of patients in the study group required positive inotropic agents compared with 18% of those in the control group ( P < 0.05). It is concluded that this difference resulted from an increase in density of β1-adrenergic receptors induced by β-adrenergic blockade, and an increase in the level of catecholamines in the early postoperative period.

Published: September 2022

A prospective study was undertaken to define the comparative value of physical examination versus duplex scanning in the detection of femoral false aneurysm and arteriovenous fistula after percutaneous femoral artery puncture. Fifty-three patients were referred to the vascular surgery service after femoral artery catheterization for evaluation of a groin hematoma or a new femoral bruit. All patients were evaluated initially by a vascular surgeon and then by duplex scan. The results of these evaluations were compared with the findings at operation. Physical examination was 100% sensitive and 100% specific in the diagnosis of arteriovenous fistula, whereas duplex scan achieved a sensitivity of only 58% and a specificity of 100%. Physical examination was 92% sensitive and 93% specific in the detection of femoral false aneurysm compared with a sensitivity of 83% and a specificity of 100% for duplex scanning. Physical examination is the best method for detecting and following patients with arteriovenous fistula. False aneurysms can be detected reliably by physical examination, although evaluation with a duplex scan is necessary to identify the precise size and anatomy of these lesions.

Published: September 2022

It is new possible experimentally to measure myocardial blood flow of the beating heart using a helium-neon (He-Ne) laser Doppler flowmeter. A myocardial probe was redesigned to reduce its size and weight, and a method devised of fixing the probe to the beating cardiac surface to allow its clinical application. This modified laser flowmeter was used on 36 patients with ischaemic heart disease to measure myocardial blood flow before and after revascularization. Flow was measured in the right and left ventricles while patients were in a haemodynamically stable state as determined by electrocardiography, heart rate, blood pressure and double product (heart rate × systolic blood pressure). No significant difference was found between the mean (s.e.m.) preoperative and postoperative flow volume at the anterior wall of the right ventricle (77(15) versus 81 (12) ml/min per 100g), which did not undergo revascularization, but mean (s.e.m.) myocardial blood flow at the ischaemic left ventricle increased significantly (from 68(15) to 88(13) ml/min per 100 g; P<0.01). There was also no significant difference between preoperative and postoperative values of haemodynamic parameters of coronary blood flow. In conclusion, a means to measure myocardial blood flow with He-Ne laser Doppler flowmetry has been devised which shows coronary artery bypass grafting to increase myocardial blood flow in the ischaemic myocardium.

Thirty-five patients (10 men and 25 women) with a preoperative diagnosis of cardiac myxoma have undergone cardiac surgery since 1964 at the University of Louvain. The mean age of the patients was 49 (range 20–75) years. The most commonly encountered symptoms were: dyspnoea 49%; thoracic pain 26%; cough and peripheral embolism 17% each; stroke and preoperative atrial fibrillation 14% each; flutter 11%; expectoration, acute pulmonary oedema, syncope and transient ischaemic attack 6% each; and pulmonary embolism 3%. The different locations were: left atrium 66%; right atrium 26%; both atria 3%; right ventricle 3%: and retrohepatic vena cavae 3%. Septal implantation was found in 66%. Histological examination confirmed 28 myxomas but three ‘tumours’ were thrombi, two haemangiomas, one rhabdomyosarcoma and one liposarcoma. The follow-up has now reached 2829 months with an average of 81 months per patient (range 0–342 months). Three patients died early (9%) and there were four late deaths (11%). No cases were familial. Surgical resection is the correct treatment for cardiac myxomas and gives good long-term results.

Published: September 2022

Undetected anatomical variations of the short saphenous vein are a major contributing factor to recurrent varicose veins in the saphenous vein area. Perioperative venography and varicography of the short saphenous vein have been proposed as a means of exact localization of its termination. The present study evaluated whether colour-coded duplex examination constituted a reliable alternative for localization of the saphenopopliteal junction. Between 1989 and 1990, 12 patients were reoperated on after previous classical ligation of the short saphenous vein. Preoperative colour-coded duplex examination revealed an abnormally high saphenopopliteal junction with persistent reflux in 11 patients and a Giacomini vein in one. When comparing these results with venographic and operative findings an accuracy of 100% was reached in these specific cases. It is concluded that for patients with recurrent varicosis of the short saphenous vein, preoperative colour-coded duplex examination provides a reliable non-invasive alternative to venography in the exact localization of the saphenopopliteal junction.

Published: September 2022

A patient with Stanford type A acute aortic dissection who developed severe cerebral dysfunction after surgery using retrograde cerebral perfusion through the superior vena cava was examined. The patient was able to regain normal brain function with no neurological deficit. Postoperative venography taken through the superior vena cava showed the presence of competent venous valves at the venous angles. This suggests that the valves interrupted cerebral perfusion, decreasing blood flow to less than that required. After consideration of the possible causes of brain damage incurred during surgery for aortic aneurysm using retrograde cerebral perfusion, it was concluded that this patient was able to recover normal brain function because the surgery was performed under profound hypothermia.

The number of adolescents with mental disorders is becoming a worldwide problem, since it has an influence not only on the health of this generation while they are still in this age group but also on their health as adults. The objective of this review aimed to focus on mental health problem and health promotion program among adolescents. The significance of mental health promotion and intervention programs in enhancing adolescents’ well-being and reducing mental health problems is highlighted in this study. There is an opportunity to apply a whole-school strategy with online curriculums. In the digital era, smartphone applications, social networking sites, and the Internet play an important role in daily life, there is an opportunity to develop a mental health promotion program. In addition, through the implementation of evidence-based programs, schools have been placed at the frontline of promoting positive mental health and well-being. The recommended intervention programs can be implemented in a variety of settings, including schools and communities, as well as through digital platforms. Therefore, adolescents’ mental health problems can be mitigated by using effective mental health promotion programs.
Revision lateral ankle ligament reconstruction for patients with a failed modified Brostrom procedure
Authors: Xu Yang , Cao Yong-xing , Li Xing-chen , Xu Xiang-yang
Published: September 2022

Purpose

The Brostrom-Gould procedure has been considered as a gold standard operative technique for chronic lateral ankle instability. Despite the popularity and excellent outcomes of the modified Brostrom procedure, some patients still experience recurrence of ankle instability. Few studies reported outcomes of revision reconstruction for patients with a failed modified Brostrom procedure. This study aimed to evaluate the outcomes of a percutaneous anatomic revision lateral ankle ligament reconstruction for patients with a failed modified Brostrom procedure.

Methods

From March 2017 to April 2020, 21 patients with persistent ankle instability after a modified Brostrom procedure underwent revision lateral ankle ligament reconstruction. The operation was performed through minimally invasive incisions. Functional assessment was performed using the Karlsson–Peterson ankle scoring system (KP) and the Visual Analogue Scale (VAS). The questionnaires of KP and VAS were completed before surgery and at the last follow-up. Patients’ subjective satisfaction level was graded as excellent, good, fair, and poor. Preoperative and postoperative anterior talar displacement and varus talus tilt angle in stress radiographs were recorded.

Results

The average age at the revision surgery time was 39.6years. The mean follow-up was 39.2months. The VAS score improved from 4.1 ± 1.5 preoperatively to 1.3 ± 1.3 at the final follow-up ( p < .05). The KP score improved from 59.0 ± 20.2 preoperatively to 88.2 ± 9.6 at the last follow-up ( p < .05). The mean varus talar tilt angle was 14.1 ± 3.9 mm preoperatively versus 4.9 ± 4.7 mm at the final follow-up ( p < .05). The mean anterior talar displacement was 12.8 ± 2.2 mm versus 5.6 ± 3.7 mm at the last follow-up ( p < .05).

Conclusions

The revision anatomic reconstruction of the lateral ligaments of the ankle is effective for patients with recurrent instability after a failed modified Broström procedure.
Effects of parasocial affinity and gender on live streaming fans’ motivations
Authors: Kneisel Ali , Sternadori Miglena
Published: September 2022

Gaming livestreams have seen unprecedented growth on platforms such as Twitch.tv and YouTube Live, especially since the start of the COVID-19 pandemic. This study examined fans’ motivations for watching and supporting their favorite streamers. The results of an online survey showed that the time spent watching livestreams was positively associated with the degree of parasocial affinity they feel toward that streamer. Parasocial affinity strength was, in turn, a significant predictor of the likelihood of sending virtual gifts or donations to streamers. Some gender differences in motivations also emerged. Women reported being more likely to watch a particular gaming stream because of the streamer’s characteristics rather than the game being played, while men were equally likely to watch because of the streamer or because of the game being played.
Event-triggered adaptive neural finite-time tracking control for non-strict feedback stochastic nonlinear systems with unknown time-varying control directions and input nonlinearities
Authors: Yue Hongyun , Zhang Wufei , Chen Qingjiang
Published: September 2022

This paper focuses on dynamic-surface-based event-triggered adaptive neural finite-time tracking control for a category of non-strict feedback stochastic nonlinear system subject to unknown time-varying control directions, and input nonlinearities. Firstly, an improved event-triggered mechanism is presented, which simultaneously considers tracking error variables and compensating for event errors in threshold value. Secondly, a novel Lemma is provided to address concurrently the issues of Nussbaum terms in stability analysis and stochastic system finite-time stability. Thirdly, neural networks are utilized to cope with unknown functions. In addition, the Nussbaum functions are applied to identify time-varying unknown control directions and input nonlinearities. Moreover, the errors of the dynamic surface technique are compensated successfully by error compensation signals. By combining the proposed Lemma 1 and event-triggered adaptive neural finite-time control scheme, finite-time stability of considered systems in probability can be guaranteed, the tracking error can drive to a small neighborhood of the origin in finite time, and the Zeno behavior can be excluded. Finally, the effectiveness of the designed control scheme has been demonstrated through a second-order numerical system and a mass-spring-damper example.

Enumeration reduction algorithm for the characterization of multi-primary LED systems
Authors: Baxter D , Durmus D , Royer M
Published: September 2022

Multi-primary tunable LED lighting systems can generate a vast number of spectral outputs, with the exact number depending on the resolution of the control signal and number of LED primaries. Computing all combinations to identify optimal spectral power distributions (SPDs) with a specified chromaticity would require a tremendous amount of time and computational power. Here, an enumeration reduction (ER) algorithm is described to reduce the computation time by defining a bounding pyramid in the three-dimensional tristimulus space that maps to the circumscribed square of the target region in the chromaticity diagram. This method enables computing only the necessary amount of tristimulus values (and resulting chromaticity coordinates) for SPDs that fall into a user-defined target chromaticity area, reducing computation time by avoiding the need to generate each combination and calculate its chromaticity coordinates. The results show that the proposed ER algorithm can greatly reduce the time – up to 922 times in a series of tests – to determine a set of metamers compared to a full enumeration computation.
Simple indicators of crime and police: How big data can be used to reveal temporal patterns
Authors: Dau Philipp M. , Dewinter Maite , Witlox Frank , Beken Tom Vander , Vandeviver Christophe
Published: September 2022

This study demonstrates how temporal summary statistics can be a guiding tool for big data analyses to unravel temporal patterns of crime and police presence. Simple indicator statistics were used to identify temporal clusters of crimes and police presence, and to investigate potential links between the two. The methodology was applied on an anonymized police database, including reported crime events and police presence data, from a medium-sized European police department. The results illustrated that certain crime types occurred more during the day (e.g., burglaries), while others were more prevalent at night (e.g., drug crimes, motorbike and car theft). Police presence showed dispersed temporal patterns and little temporal focus on any type of crime. The research shows that temporal summary statistics can be used to support an explorative analysis of big datasets and guide subsequent spatiotemporal analyses of crime and police data. The summary statistics offer an accessible approach to analysing extensive datasets of policing activity and improving evidence-based policing strategies.

Purpose:

To review the early experience of the use of a bifurcated-fenestrated endograft (Bif-FEVAR) to treat abdominal aortic aneurysms (AAA) in a high-volume aortic center.

Methods:

A retrospective single-center analysis was conducted between March 2019 and April 2021 including consecutive patients that underwent Bif-FEVAR. Only patients without a proper infrarenal neck and a distance <70 mm between the lowest target artery and the native or prosthetic aortic bifurcation were considered. All Bif-FEVAR custom-made devices were manufactured by Cook Medical (Inc., Bloomington, Indiana). Demographics, anatomical features, technical success, major adverse events, 30-day mortality, and survival according to Kaplan–Meier were analyzed according to Society for Vascular Surgery standards.

Results:

Overall, 10 patients (100% male with median age 78) were included. The median preoperative maximal aneurysm diameter was 68 mm [51–84]. Eight patients were treated for a proximal type I endoleak after endovascular aneurysm repair. A total of 36 fenestrations were planned. The median operative time was 144 min [127–168], with a median fluoro time of 40.5 min [34–54] and a median dose area product of 73 Gy cm2 [61–89]. Technical success rate was 100%. No patients experienced a major postoperative adverse event. Median follow-up time was 8 months [6–13].

Conclusion:

Bif-FEVAR is technically feasible when there is a short distance below the lowest target artery and the aortic bifurcation, with favorable short-term results.

Clinical Impact

This study assessed the use of an innovative one-piece bifurcated fenestrated stent-graft as a primary procedure or in the treatment of proximal endoleak after standard infrarenal EVAR. We demonstrated these custom-made devices can be used safely with favorable short-term results. One-piece bifurcated fenestrated stent-grafts extend the indications of FEVAR for patients with an unusually short distance between the lowest renal artery and the aorto-iliac bifurcation or the diverter flow of a preexisting bifurcated infrarenal stent-graft.
Engaging Dispositional Forgiveness: A Structure for Consistent Forgiveness Praxis
Authors: Githuthu Florence Wamahiga , Gicheru Esther N.
Published: September 2022

Although forgiveness is hard work, it enables individuals who have gone through unfairness and harm outgrow the pain of resentment and hostility to a condition of wellness and health. Still, it is possible that authentic forgiveness, regardless of significant violations may, as a matter of choice occur when the injured have hitherto achieved proficiency with the forgiveness praxis by practicing consistently. This manuscript suggests a brief dispositional forgiveness praxis that permits individuals to achieve experience in forgiving trivial faults on a consistent basis. Even though other forgiveness practices are in existence, this praxis is distinctive in that it draws from a philosophically and scientifically firm appreciation of the forgiveness procedures and is supposed to build up ones’ capacity to forgive in the circumstances of more difficult wounding and unfairness that may occur ahead. Individual persons engage in this praxis by meditating upon smaller instances of wrongdoing from their everyday life and wade through six steps, each informed by inquiry in forgiveness counseling and self-understanding; to move from anger to empathy. A case study is provided to demonstrate one personal experience in engaging in one of consistent forgiveness praxis in the repercussions of a small wrongdoing.
Open Access and Sensitive Social Sciences Data in Different Legislative Contexts: The Case of Strategic Selection “Elite” Interviewing in Sweden
Authors: Keskitalo E. C. H.
Published: September 2022

Open access has moved from the periphery to the mainstream in the last few years, and most recently there have been calls to make research data “accessible, useable and reusable”. While there are many good arguments for this development, including that it makes the research process more transparent and enables others to re-use the data collected, it also has negative implications for social science research in certain contexts. The case addressed here is “elite” interviewing in the context of conducting research in Sweden. In this case there is already a strong legislative focus on openness with implications for research ethics. This suggests that open data access implementation, particularly in the context of specific legislative frameworks, needs to be reviewed to ascertain ethically correct interviewee and research subject protection in the social sciences.

The development of a simple, inexpensive, sensitive, and selective spectrofluorometric assay method for taurine in energy drinks utilizing 4-fluoro-7-nitro-2,1,3-benzoxadiazole as a fluorogenic agent is described. Conditions affecting the derivatization reaction are investigated and optimized. The optimal conditions are found to be as follows: buffer, pH 10; 4-fluoro-7-nitro-2,1,3-benzoxadiazoleconcentration, 0.05%; reaction time, 30 min; temperature, 50 °C. Fluorescence measurements are carried out at a wavelength of 542 nm, with excitation at a wavelength of 485 nm. The method is validated under the optimum conditions. The method is found to be linear in the range of 2.0–12.5 µg/mL, with a correlation coefficient of 0.9993. The limits of detection and quantification (µg/mL) are 0.6 and 2.02, respectively, which are appropriate for taurine assays in commercial energy drinks. In addition, the proposed method recorded excellent accuracy since the recovery values caused by presence of excipients are found to be in the range of 99.3%–102.87%. The values of relative standard deviation for intra- and inter-day precision were found to be in the ranges of 0.236%–0.659% and 2.12%–2.63%, respectively.

A new eremophilane-type sesquiterpene glucoside, 13-hydroxycapsidiol 3- O- β-D-glucoside (1), was isolated from the leaves of Nicotiana tabacum L. The structure of this new metabolite was determined by one-dimensional (1D) and 2D nuclear magnetic resonance (NMR) spectroscopy, high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), and comparison with values reported in the literature. Compound 1 was the second glycosylated eremophilane sesquiterpenoid isolated from plants of the Solanaceae family and exhibited a more potent anti-tobacco mosaic virus (anti-TMV) activity, with an inhibition rate of 39.4% at 20 μM, than the positive control ningnanmycin (34.8%).

Published: September 2022

Minimally invasive approaches for the Achilles tendon have emerged as viable alternatives for acute Achilles ruptures, with several potential benefits in comparison to the open approach. Occasionally, proper purchase in the proximal tendon stump is not achieved due to severe degenerative disease of the tendon. In this article, we present a technique in which a small accessory incision is used during percutaneous Achilles repair in order to pass the sutures in a more proximal and healthy area of the tendon. This technique is useful for situations in which adequate tendon grasp is not obtained, avoiding the need of conversion to an open approach.

Older adults’ perceptions of oral health and its influence on general health: A deductive direct content analysis
Authors: Snogren Maria , Eriksson Irene , Browall Maria , Ek Kristina
Published: September 2022

Oral health is a complex issue associated with social and behavioral factors and general health. Therefore, this study aims to explore Swedish older adults’ perceptions of oral health and its influence on general health, based on the World Dental Federation's (FDI) definition and framework of oral health. The study adopted a descriptive qualitative design. Data were collected from semi-structured individual and focus group interviews with older adults ( n = 23) and were analyzed with deductive direct content analysis. The study was evaluated using the COnsolidated criteria for REporting Qualitative research (COREQ) checklist. The older adults described the importance of good oral health in the physical, social, emotional, and mental aspects of their daily lives. The findings also indicate that older adults described oral health as multifaceted and agreed with the FDI's definition and framework of oral health. Therefore, the study findings might provide healthcare professionals with new knowledge and further insight into older adults’ perceptions of oral health and its influence on their well-being and general health.

Published: September 2022

Background:

The Chronic Pain Self-Management Program is an evidence-based intervention that has been shown to be efficacious in reducing symptoms of chronic pain. However, there is a paucity of research examining CPSMP in a predominantly rural population. The purpose was to evaluate patient-reported outcomes of in-person peer-led CPSMP workshops offered in a rural region in 2018 and 2019.

Methods:

Participants were surveyed at baseline and 6 months post-workshop. Descriptive statistics were used to describe characteristics of CPSMP completers. Paired t-tests were used to analyze change in depression score (PHQ-8), disability (modified Roland-Morris Disability Questionnaire), self-efficacy, and patient activation (PAM-10). Analysis of variance was used to detect differences over time by age group, education, insurance type, self-rated health, and comorbidities.

Results:

Among the 327 adults who enrolled in a workshop, 73.1% completed. Of completers, 74.9% were female, average age was 65. Significant improvements were observed in pain disability ( P = .0008), patient activation ( P = .0362), depression ( P < .0001), and self-efficacy ( P < .0001), at 6 weeks; and pain disability ( P = .0030), depression ( P = .0015), and self-efficacy ( P = .0064) at 6 months post-program. Individuals who rated their health as fair/poor at baseline reported greater improvements in depression scores than individuals who rated their health as good or better ( P < .0002). There were also distinct patterns of change in pain disability among the different age groups. No other differences between groups were noted.

Conclusions:

The CPSMP appears to improve pain self-efficacy, disability, and depression regardless of age, gender, insurance status, education, or comorbidities. Healthcare and community organizations should consider investing in and offering chronic pain workshops in rural areas in order to promote health and wellness.
Heading Up or Stuck Down Here? The Effect of Perceived Economic Mobility on Subjective Social Status and Brand Identification
Authors: Lee Eunkyung , Yoon Yeosun
Published: September 2022

In this research, we show that the perception of economic mobility plays an important role in individuals’ minds and decisions. While previous literature on economic mobility mainly focused on measuring the degree of mobility and examining its socioeconomic ramifications, we extend prior research by investigating the psychological consequences of economic mobility perception. Through three studies, we propose and demonstrate that those who perceive the economic mobility of their societies to be high (vs. low) tend to perceive their current social status to be higher. We argue that individuals’ hope and the subsequent perception of psychological distance to the upper levels of the socioeconomic ladder serially mediate this relationship. We further show that such perception of economic mobility influence the degree to which individuals identify with high-status brands and their purchase likelihood.
Mast Cell Sarcoma of the Retroperitoneum With Concurrent Systemic Mastocytosis and an Undisclosed Associated Hematologic Neoplasm: A Case Report
Authors: Chen Ing , Liao Jia-Bin , Lin Jung-Chia , Hsieh Pin-Pen , Hsieh Ming-Yun
Published: September 2022

Mastocytosis is a rare disorder affecting both children and adults by gathering of functionally defective mast cells in the body’s tissues. The World Health Organization (WHO) classified mastocytosis into cutaneous mastocytosis, systemic mastocytosis (SM), and mast cell sarcoma (MCS). We hereby present a case of retroperitoneal MCS with concurrent systemic mastocytosis and an undisclosed associated hematological neoplasm (SM-undisclosed AHN). The diagnosis of MCS and SM was made after the second biopsy over retroperitoneal mass, lymph node, and ovary for rapidly progressive disease with the presentation of unexplained recurrent flushing, palpitation, and shock, in addition to abdominal pain. A clonal myeloid neoplasm was also suspected by the karyotype and hemogram data. Unfortunately, the patient succumbed to the disease quickly. Apart from this unique case, the previously reported cases of SM with MCS in the literature were also reviewed.
