Compact multi‐band chipless RFID resonators for identification and authentication applications
Authors: Babaeian F. , Karmakar N.C. 
Published: April 2020

Moving towards commercialisation of chipless RFID systems, there are still some pressing issues. In the tag design level, the issues are high data capacity in the order of tens of bits, compact design and the immunity to the interference which can be achieved by a cross‐polar response. It is demanded to yield the highest numbers of bits in a tag ID while the occupied physical space and allocated bandwidth are minimised. Increasing the number of resonators in a conventional multi‐resonator chipless tag causes a significant tag size growth. The destructive coupling effect between resonators in multi‐resonator tags is another critical issue. In this Letter, to combat those issues, a multi‐band resonator is proposed. The comb‐shaped tags contain both co‐polar and cross‐polar Radar cross section (RCS) responses, hence they can be used in high reflective environments. Two samples of 14‐bit and 40‐bit comb‐shaped tags are designed, which have physical sizes of 17 mm × 13 and 30 mm × 45 mm, respectively. The promising performance of the proposed structure, which is beyond the state of art hybrid and frequency‐domain tags, shows the potential of the proposed designs for identification and authentication applications.

Published: April 2020

Abstract
Objective Investigating the correlation between subjective and objective VA (visual acuity) elicited with a newly developed computerised optokinetic nystagmus (OKN) suppression test (“SpeedWheel”) in adults.
Methods SpeedWheel presented alternating black/white stripes moving horizontally across a LED screen. Seven VA steps were induced with Bangerter filters placed onto spectacle frames. Magnified eye movements were projected from infrared cameras inside the frames and displayed onto a smartphone. Dots whose size increased in logarithmic steps were superimposed to suppress OKN. Suppression of OKN resulted in the SpeedWheel acuity which was then correlated to Snellen acuity as measured with the Freiburg Acuity test.
Results 28 eyes from 14 individuals were tested. FrACT-E correlated well to SpeedWheel (r: 0.89; p < 0.001). Snellen acuity was never lower than 0.14 LogMAR of SpeedWheel values. Bangerter filters showed greater mean difference to both methods indicating that this filter is not as predictable as suggested by the filter value.
Conclusion SpeedWheel offers a fast (< 80 sec) and reliable alternative option to measure objective VA.

Abstract
Purpose To evaluate the diagnostic performance of strain elastography (SE) and 2 D shear wave elastography (SWE) and SE/SWE combination in comparison with conventional multiparametric ultrasound (US) with respect to improving BI-RADS classification results and differentiating benign and malignant breast lesions using a qualitative and quantitative assessment.
Materials and Methods In this prospective study, 130 histologically proven breast masses were evaluated with baseline US, color Doppler ultrasound (CDUS), SE and SWE (Toshiba Aplio 500 with a 7–15 MHz wide-band linear transducer). Each lesion was classified according to the BIRADS lexicon by evaluating the size, the B-mode and color Doppler features, the SE qualitative (point color scale) and SE semi-quantitative (strain ratio) methods, and quantitative SWE. Histological results were compared with BIRADS, strain ratio (SR) and shear wave elastography (SWE) all performed by one investigator blinded to the clinical examination and mammographic results at the time of the US examination. The area under the ROC curve (AUC) was calculated to evaluate the diagnostic performance of B-mode US, SE, SWE, and their combination.
Results Histological examination revealed 47 benign and 83 malignant breast lesions. The accuracy of SR was statistically significantly higher than SWE (sensitivity, specificity and AUC were 89.2 %, 76.6 % and 0.83 for SR and 72.3 %, 66.0 % and 0.69 for SWE, respectively, p = 0.003) but not higher than B-mode US (B-mode US sensitivity, specificity and AUC were 85.5 %, 78.8 %, 0.821, respectively, p = 1.000).
Conclusion Our experience suggests that conventional US in combination with both SE and SWE is a valid tool that can be useful in the clinical setting, can improve BIRADS category assessment and may help in the differentiation of benign from malignant breast lesions, with SE having higher accuracy than SWE.

Abstract
Background Ligaments injury and anterior knee pain is the most common problem in the knee joint. In practice, there are various interventions for the treatment of patellofemoral pain syndrome (PFPS). Kinesio taping is one of them, but little literature is available on the immediate effects of treating this problem.
Methodology From June to September 2017, a randomized control study was conducted at the Army Sports Complex GHQ Rawalpindi to determine the effectiveness of Kinesio Taping (KT) in patellofemoral pain syndrome in athletes. Data were collected from 48 athletes who fully met the inclusion criteria and were randomly divided into 2 groups. The data collection tool was Numerical Pain Rating Scale (NPRS), Kujala PFPS Score, and self-structured Questionnaire. The data was analyzed on SPSS 21.
Results The overall mean age was 22.7±3.0. The immediate effects showed improved NPRS in both groups; in the control group the NPRS pre 1st visit mean was 5.36±1.2 and post 1st visit mean was 4.68±1.3 with the difference of 0.68±0.1 having p value p<0.001. In the treatment group the NPRS pre 1st visit mean was 5.90±1.2 and post 1st visit mean was 5.00±1.0 with the difference of 0.90±0.1 having p value p<0.001.
Conclusion This study shows immediate effects of Kinesio-Taping, however there was not any significant difference between both groups but the treatment group performed well after the sessions.
Lemierre Syndrome: A Meta-analysis
Authors: Gore Mitchell R. 
Published: April 2020

Abstract
Introduction Lemierre syndrome, or postpharyngitis anaerobic sepsis, is an infrequent but life-threatening infection that often involves thrombosis of the internal jugular vein. The role of anticoagulation in addition to antibiotics and surgical treatment remains uncertain.
Objectives 1) To perform a meta-analysis on outcomes and treatment of Lemierre syndrome; and 2) to evaluate the effect of anticoagulation in Lemierre syndrome on vessel recanalization and on mortality.
Data Synthesis A Pubmed database search was conducted using the keywords Lemierre syndrome. A total of 427 studies were identified and reviewed. Data were extracted on patient demographics, treatment type including use and type of anticoagulation, type of antibiotics, presence and location of vessel thrombosis, presence of cranial neuropathies, recanalization of thrombosed vessels on follow-up imaging, organisms isolated on wound or blood cultures, and mortality. The primary outcome variables examined were the effect of anticoagulation on vessel recanalization and mortality. After the review, 359 studies totaling 394 patients between 1990 and 2017 had partial or complete data that could be analyzed. In total, 50 patients had sufficient data on the effect of anticoagulation on vessel recanalization, and 194 had sufficient data on the effect of anticoagulation on mortality. The odds ratio for anticoagulation and vessel recanalization was 1.6 (95% confidence interval = 0.3 to 9.4; p = 0.6). The odds ratio for anticoagulation and death was 0.6 (95% confidence interval = 0.1 to 2.9; p = 0.5).
Conclusion The present meta-analysis did not demonstrate a statistically significant effect on vessel recanalization or mortality for patients treated with anticoagulation versus patients not anticoagulated in the Lemierre syndrome literature.

Published: April 2020

Abstract
Introduction Multiple incisions have been described for the surgical approach of cervical neck nodes. All of these descriptions are associated with better or worse exposure of the surgical field as well as with different functional and aesthetic results, which are not always satisfactory.
Objective Compare the transverse cervical incision with the classic incision in J or U.
Methods This is a retrospective study of 47 patients who required cervical neck dissection between June 15, 2016 and June 15, 2017.A transversal incision was made in these surgeries, and their results were then compared with those of a group of 57 patients treated between January 1, 2010 and January 1, 2012, in whose cases an incision in J or U was made.
Results Regarding the incision type, complications were present in 4 (8.5%) cases in the transversal incision group, and in 7 (12.2%) patients of the group of traditional incisions in J or U, without statistical differences (p = 0.078). The only variables associated with complications of healing in the two groups was body mass index (BMI) < 18.5. The patients showed subjective satisfaction with the aesthetic result of the transverse incision, with an average of 7.51 vs 6.20 in the J or U incision.
Conclusion The transverse incision represents a safe, aesthetic, and oncologically adequate option, associated with a lower cicatricial retraction rate, without significant complication rate and allowing adequate exposure of the surgical field, similar to the obtained with the classic incision in J or U.

Published: April 2020

Abstract
Introduction Dysphagia is a relevant symptom in Parkinson disease (PD), and its pathophysiology is poorly understood. To date, researchers have not investigated the effects of combined motor tasks on swallowing. Such an assessment is of particular interest in PD, in which patients have specific difficulties while performing two movements simultaneously.
Objective The present study tested the hypothesis that performing concurrent tasks could decrease the safety of swallowing in PD patients as visualized using fiberoptic endoscopic evaluation of swallowing (FEES).
Methods A total of 19 patients and 19 controls matched by age, gender, and level of schooling were compared by FEES under two conditions: isolated swallowing and dual task (swallowing during non-sequential opposition of the thumb against the other fingers). The two tasks involved volumes of food of 3 mL and 5 mL. The PD subjects were classified according to the Hoehn & Yahr (H&Y) Scale, the Mini Mental State Examination (MMSE), and the Montreal Cognitive Assessment (MoCA). The FEES assessment was performed according to the Boston Residue and Clearance Scale (BRACS).
Results The data showed a significant worsening of swallowing in the dual task assessment for both volumes (3 mL: p ≤ 0.001; 5 mL: p ≤ 0.001) in the PD group. A correlation between the MoCA and dual-task swallowing of 3 mL was also found.
Conclusion These findings suggest that additional tasks involving manual motor movements result in swallowing impairment in patients with PD. Moreover, these data highlight the need to further evaluate such conditions during treatment and assessment of PD patients.

Published: April 2020

Abstract
Introduction Mucociliary clearance (MCC) is the first line of defense of the pulmonary system. Mucociliary clearance impairment may lead to increased risk of respiratory infections, lung injury, pulmonary repair problems, chronic dysfunctions and progression of respiratory diseases.
Objective To characterize the MCC of active and passive smokers and individuals with chronic obstructive pulmonary disease (COPD) and compare the MCC behaviors between men and women of different age groups.
Methods Patients with COPD (current smokers and ex-smokers) and apparently healthy individuals (current smokers, passive smokers and nonsmokers) were evaluated. All of the subjects underwent lung function and MCC evaluation (saccharin transport test [STT]). Smokers (with or without COPD) were questioned about the smoking history.
Results A total of 418 individuals aged 16 to 82 years old, of both genders, were evaluated. The STT values of active and passive smokers were statistically higher than those of the control group (p < 0.01). Men of the control group had lower values of STT than active smokers (9.7 ± 7.1 and 15.4 ± 10.1 minute, respectively, p < 0.01). In addition, higher MCC velocity was observed in women that are current smokers (11.7 ± 6.8 minute) compared with men (15.4 ± 10.1 minute) in this group (p = 0.01). Among the younger age groups (< 50 years old), only passive smokers presented higher STT in relation to the control group.
Conclusion Passive and active smoking are factors that influence negatively the MCC, and passive smokers may present losses of this mechanism at a younger age. Additionally, male smokers present worse MCC than male nonsmokers.

Published: April 2020

Abstract
Introduction Inspiratory maneuver corresponds to a simple method used during videolaryngoscopy to increase characterizations of laryngeal findings, through the movement of the vocal fold cover and exposure of the ligament, facilitating its evaluation.
Objective To evaluate the increase in diagnosis of benign laryngeal lesions from the usage of inspiratory maneuvers during videolaryngoscopy in patients with or without vocal complaints.
Methods A cross-sectional study performed from March 1 to July 1, 2018, in the Laryngology sector of a tertiary hospital. The age of the patients varied from 18 to 60 years old. They were divided into two groups, symptomatic and asymptomatic vocals, and evaluated through videolaryngoscopy together with inspiratory maneuvers. The exams were recorded and later evaluated by three trained laryngologists who determined the laryngeal lesions before and after the inspiratory maneuver.
Results There were 60 patients in this sample, 41 of which were vocal symptomatic and 19 asymptomatic. The majority was female and the main complaint was about dysphonia. Before the inspiratory maneuver, the most observed lesions in both groups were chronic laryngitis, followed by vascular dysgenesis. After the inspiratory maneuver, sulcus vocalis was the most frequent additional finding.
Conclusion With the inspiratory maneuver, it was possible to increase the identification of structural lesions in the vocal fold, and the most frequent lesion in patients with or without vocal complaints was sulcus vocalis.

Abstract:
Background: Many efforts have been made to discover new antimicrobial compounds from various sources such as micro-organisms, animals and plants. Use of herbal medicines has a long history in Asian population in treating different ailments. Many plants have been found to have properties like antibacterial, antifungal and antioxidant activities.In a complete denture wearer, due to either local or systemic factors, denture stomatitis has been found to a have high prevalence. In such patients, higher incidence of Candida infection and increased levels of Candida spp. also have been identified. Existing antifungal agents like Nystatin & Fluconazole have been found to have toxic effects on long term application and chances of development of drug resistance is high. Medicinal plants have been used to inhibit growth and development of fungal infection from Candida isolated from sites other than oral cavity.
Objectives: To evaluate the antifungal activity of some of the medicinal essential oils against oral isolates of Candida obtained from denture wearing patients identified through a survey.
Materials and Methods: The oral isolates of Candida species were collected after conducting a survey of complete denture wearers, wearing the denture for at least more than a year. The speciation of the organism was done after identifying it from the specimens. It was confirmed with the help of germ tube test, other biochemical tests and chlamydospore formation tests. A lab isolate also was included in the study. The essential oils of different herbs were extracted using hydro distillation methods. The antifungal activity of these oils was tested and compared with antifungal activity of Nystatin and fluconazole using modified Kirby-Baeur method. The inhibition zones of different oils were measured and compared among themselves against all the clinical isolates and the lab isolate.
Results: About 55 complete denture wearing patients have been surveyed and among them 27 have been found to be positive for Candida-associated denture stomatitis. Among the Candida species, Candida albicans was more prevalent followed by C. tropicalis and C. glabrata.Among the test essential oils, Origanum vulgare (stored & fresh) and clove oil gave positive results against all isolates. The fresh samples gave better results than the stored and all three oils showed more antifungal activity than Nystatin & fluconazole.
Interpretation: The candida-associated denture stomatitis is prevalent in patients who are wearing
denture prosthesis for more than a year.Candida albicans is the most prevalent causative species followed by C. tropicalis and C. glabrata.Origanum vulgare and clove oil are potent antifungal agents against oral species of Candida. They can be either used separately or their synergistic activity could be explored against denture stomatitis.

Abstract:
Background & Objectives: Hepatitis B is the most important infectious occupational disease for the health care workers. Dental surgeons are frequently in contact with blood and saliva and hence are at high risk for Hepatitis B Virus (HBV) exposure. HBV infection is a major public health problem in India, as there are 45 million estimated carriers. Immunization against HBV reduces the risk of transmission of HBV to dental personnel and from dental personnel to patients. The present study was aimed to evaluate the serum levels of anti-HBs in vaccinated dental health care workers.
Methods: In this study, estimation of serum levels of Anti- HBs in 40 dental students vaccinated against HBV was done. Data was obtained regarding vaccination data, age, sex, weight, height and smoking history. Anti-HBs level was evaluated two years after the 1st dose of vaccination. Low responders were given booster vaccination and post booster anti HBs assay was done.
Results: The study included 110 hepatitis B vaccinated dental students. Out of 110 students only 40 students had documented history of complete vaccination and volunteered to be a part of the study. Among these 40 students, three students (7.5%) had less than 100 IU/L anti–HBs level and 37 students (92.5%) had more than 100 IU/L anti–HBs level. Anti- HBS level above 100 IU/L is identified to be protective. Following booster vaccination, low responders showed anti -HBs titre more than 100 IU/L.
Conclusion: In this study majority dental students had desirable immune response to the HBV vaccine. Male gender and positive smoking history could have attributed to low anti-HBs titre in subjects who had inadequate levels in our study. Hence, all Health Care Workers, in particular dental surgeons with contributory factors like smoking habit, male gender should undergo periodic assessment of anti-HBs titre.
