A useful family of integral operators and special functions plays a crucial role on the study of mathematical and applied sciences. The purpose of the present paper is to give sufficient conditions for the families of integral operators, which involve the normalized forms of the generalized Lommel functions of the first kind to be univalent in the open unit disk. Furthermore, we determine the order of the convexity of the families of integral operators. In order to prove main results, we use differential inequalities for the Lommel functions of the first kind together with some known properties in connection with the integral operators which we have considered in this paper. We also indicate the connections of the results presented here with those in several earlier works on the subject of our investigation. Moreover, some graphical illustrations are provided in support of the results proved in this paper.

The image super-resolution reconstruction method can improve the image quality in the Internet of Things (IoT). It improves the data transmission efficiency, and is of great significance to data transmission encryption. Aiming at the problem of low image quality in image super-resolution using neural networks, a self-attention-based image reconstruction method is proposed for secure data transmission in IoT environment. The network model is improved, and the residual network structure and sub-pixel convolution are used to extract the feature of the image. The self-attention module is used extract detailed information in the image. Using generative confrontation method and image feature perception method to improve the image reconstruction effect. The experimental results on the public data set show that the improved network model improves the quality of the reconstructed image and can effectively restore the details of the image.
Rapid computation of effective conductivity of 2D composites by equivalent circuit and spectral methods
Authors: Ransom Ben J. ,   Department of Chemical Engineering, Brigham Young University, Provo, Utah 84602, USA, Wheeler Dean R.
Published: August 2021

This work presents models for homogenizing or finding the effective transport or mechanical properties of microscale composites formed from highly contrasting phases described on a grid. The methods developed here are intended for engineering applications where speed and geometrical flexibility are a premium. A canonical case that is mathematically challenging and yet can be applied to many realistic materials is a 4-phase 2-dimensional periodic checkerboard or tiling. While analytic solutions for calculating effective properties exist for some cases, versatile methods are needed to handle anisotropic and non-square grids. A reinterpretation and extension of an existing analytic solution that utilizes equivalent circuits is developed. The resulting closed-form expressions for effective conductivity are shown to be accurate within a few percent or better for multiple cases of interest. Secondly a versatile and efficient spectral method is presented as a solution to the 4-phase primitive cell with a variety of external boundaries. The spectral method expresses the solution to effective conductivity in terms of analytically derived eigenfunctions and numerically determined spectral coefficients. The method is validated by comparing to known solutions and can allow extensions to cases with no current analytic solution.

Published: August 2021

Identification of the receptors involved in innate immune recognition of Staphylococcus aureus, a major cause of morbidity and mortality in humans, is essential to develop alternative strategies to treat infections caused by antibiotic-resistant strains. In the current study, we examine the role of endosomal TLRs, which sense the presence of prokaryotic-type nucleic acids, in anti-staphylococcal host defenses using infection models involving genetically defective mice. Single deficiencies in TLR7, 9, or 13 resulted in mild or no decrease in host defenses. However, the simultaneous absence of TLR7, 9, and 13 resulted in markedly increased susceptibility to cutaneous and systemic S. aureus infection concomitantly with decreased production of proinflammatory chemokines and cytokines, neutrophil recruitment to infection sites, and reduced production of reactive oxygen species. This phenotype was significantly more severe than that of mice lacking TLR2, which senses the presence of staphylococcal lipoproteins. Notably, the combined absence of TLR7, 9, and 13 resulted in complete abrogation of IL-12 p70 and IFN-β responses to staphylococcal stimulation in macrophages. Taken together, our data highlight the presence of a highly integrated endosomal detection system, whereby TLR7, 9, and 13 cooperate in sensing the presence of staphylococcal nucleic acids. We demonstrate that the combined absence of these receptors cannot be compensated for by cell surface-associated TLRs, such as TLR2, or cytosolic receptors. These data may be useful to devise strategies aimed at stimulating innate immune receptors to treat S. aureus infections.

Authors: Bahamondes González Luis Andrés , Aránguiz Kahn Luis , Marín Alarcón Nelson
Published: August 2021

El así llamado estallido social que comenzó en Chile el día 18 de octubre de 2019 se ha vuelto un caso de excepcional interés para diversas disciplinas de las ciencias sociales y humanidades. No obstante, en el consiguiente debate público que el acontecimiento ha producido, también han estado involucradas instituciones evangélicas interpretando las problemáticas que el estallido social ha visibilizado. Este trabajo exploratorio aborda la relación entre religión, política y cambio social en un escenario de deterioro de la confianza en las instituciones religiosas en el Chile de postdictadura. A través de la revisión de las diversas interpretaciones que se han hecho del estallido en el debate público se busca analizar discursivamente la recepción del estallido en actores evangélicos. En este sentido, la presente investigación se propone analizar el modo en que las agrupaciones evangélicas construyen espacios de visibilización y reconocimiento público en un contexto de crisis de la democracia.
Antropología del milenarismo: el premilenarismo entre los adventistas y pentecostales en los espacios fronterizos chileno-bolivianos
Authors: Mansilla A. Miguel Ángel , Leiva Sandra
Published: August 2021

El objetivo de este artículo es analizar las condiciones culturales y las propuestas teóricas del premilenarismo y sus usos como recursos por parte de las comunidades religiosas presentes en los espacios fronterizos chilenos y bolivianos. Para ello hemos dividido el artículo en tres partes: (i) Mitos milenarios en espacios (trans)andinos, (ii) Teorías sobre el milenarismo y (iii) El (pre)milenarismo en la frontera chileno-boliviana. De igual modo, este último apartado lo dividimos en tres partes, sobre el uso y transformación del premilenarismo por parte de las comunidades adventistas y pentecostales como recurso triple: social, político y simbólico, lo que rompe con el mito sobre el premilenarismo concebido como huida y quietismo social. En consecuencia, se constituye en una creencia que acciona al creyente, no solo en la esperanza de la movilidad social en el más allá, sino en la posibilidad del cambio social en el más acá.
New therapeutic applications of ozenoxacin in superficial skin infections
Authors: García Ron Gema , Villa Arranz María
Published: August 2021

In recent years, the incidence of community-acquired methicillin-resistant S. aureus skin infections (CA-MARSA) has increased in pediatric population without associated risk factors. Ozenoxacin 10mg/g is a topical quinolone that has shown high activity on strains of S. aureus, S. pyogenes and other Gram-positive bacteria sensitive and resistant to methicillin, other quinolones, mupirocin and fusidic acid. Ozenoxacin 10mg/g cream was applied twice a day for 5 days in pediatric patients with superficial skin infections other than non-bullous impetigo where oral antibiotics were not needed. Therapeutic success was achieved in 93.7% of the patients after 5 days of treatment, with a 98.2% decrease in the mean SIRS scale of symptoms. No adverse reaction was reported during treatment. Given the achieved effectiveness, safety, and adherence of the treatment, we believe that pediatricians should consider this topical antibiotic for the treatment of other superficial skin infections, without limiting its use to non-bullous impetigo.

Published: August 2021

A soccer player should possess a reasonable level of different skills and abilities, so the playing position, level of training, style of play, physical and physiological demands can influence his performance. The objective was to identify the intervention programs that have been applied in search of generating positive effects on explosive strength and speed in young soccer players, as well as to identify the percentage of improvement among soccer players. A bibliographic study of systematic review was carried out. Following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement, bibliographic searches were performed in the PubMed database. The following descriptors were used: Explosive Strength, soccer players, jump performance, CMJ, SJ, VJ, Plyometrics, power, speed, sprint, kicking speed, change of direction speed, soccer player, football and training, intervention. Articles were included only if they were original articles, studied populations of young soccer players and showed an intervention program related to explosive strength and speed. Six studies were identified that applied intervention programs to look for changes in speed and explosive strength in young soccer players. In the 5m speed tests, significant changes were observed, improving from (0.26 to 0.53m/s), 10m speed (0.07 to 0.27m/s), 20m speed (0.08 to 1.92m/s) and 40m speed (0.25 to 0.62m/s). In explosive strength, performance in the test squat jump SJ (4.1 to 8.6cm), countermovement jump CMJ (1.0 to 8.8cm), horizontal jump HJ (12.17 to 24.4cm) and vertical jump VJ (5.0 to 11.0cm). Speed and explosive strength are relevant components of athletic performance and can be improved through training programs that include 20 to 40min sessions, training two to five times per week over a period of approximately 6 to 9 weeks.
Knowledge of and Attitudes toward Health and Cardiovascular Disease Risk Factors among Firefighters in Cape Town, South Africa
Authors: Ras Jaron , Mosie Duncan , Strauss Matthew , Leach Lloyd
Published: August 2021

Background

Firefighting is a hazardous occupation, and the firefighters’ fitness for duty is affected by their knowledge of and attitudes toward their health and their relationship in the development of cardiovascular disease (CVD). The aim of this study was to assess knowledge and attitude toward health and CVD risk factors among firefighters in South Africa.

Design and methods

The study used a cross-sectional research design. A sample of 110 firefighters, males and females, aged 18 to 65 years were conveniently sampled from the City of Cape Town Fire and Rescue Service. A researcher-generated selfadministered questionnaire was completed online to obtain data from firefighters. A p-value of less than 0.05 indicated statistical significance.

Results

The results showed that 52.8% of firefighters had a poor knowledge of health, and 47.2% had a good knowledge of health, while 10% reported a negative attitude towards health and 90.0% had a positive attitude towards health. There was a significant difference between firefighters’ knowledge of health and their attitudes toward health (P<0.05), particularly related to marital status, age, years of experience and in those with CVD risk factors (P<0.05). Significant correlations were found between knowledge of CVD and knowledge of health-risk behaviours (P<0.05).

Conclusion

Significant differences in health knowledge and attitudes toward health were present in married, aged and hypertensive firefighters. Overall health knowledge and health-risk behaviours were significant predictors of attitudes toward health.

Published: August 2021

The study aimed to verify whether exercise training in older adults can improve social behavioral rhythms (SBR) and if any modification is maintained over time. Older adults (n=120) from a previous randomized controlled trial (RCT), were randomly allocated to either a moderate-intensity exercise group or a control group. SBR was evaluated at t0, t26, and t48 weeks (during the COVID-19 lockdown), using the brief social rhythms scale (BSRS). Seventy-nine participants completed the follow-up (age 72.3±4.7, women 55.3%). An improvement in the BSRS score was found in the exercise group at 26 weeks (p=0.035) when the exercise program was concluded, and it was still maintained at 48 weeks (p=0.013). No improvements were observed in the control group. To conclude, social behavioral rhythms (SBR), previously found as a resilience factor in older adults during Covid-19, appear to improve after a moderate 12 weeks exercise program, and the improvement persisted even after stopping exercise during the COVID-19 lockdown.
Effect of water saturation on some mechanical properties of the Lac du Bonnet pink granite
Authors: Lau J S O , Gorski B
Published: August 2021

Uniaxial compression tests were conducted on pink granite core specimens to explore the possibility of water-weakening of the rock. Tests were performed at a stress rate of 0.75 MPa/s and at room temperature.
The water-saturated specimens were observed to display a slightly lower peak strength and strength at the onset of stable crack growth, compared with dry specimens. However, water saturation appeared to have no effect on the strength at the onset of unstable crack growth, tangent Young's modulus and
Poisson's ratio.
The effects of loading rate and temperature should be investigated in any further study on the water-weakening trend of the granite.
Obsessive belief and emotional appraisal correlates of symptom dimensions and impairment in obsessive–compulsive disorder
Authors: Sinha Reema , Mahour Pooja , Sharma Eesha , Mehta Urvakhsh M. , Agarwal Manu
Published: August 2021

Background:

Obsessive–compulsive disorder (OCD) is a heterogeneous and debilitating illness. Symptom dimensions of OCD lend homogeneous avenues for research. Variations in one's appraisal of thoughts and emotions can influence symptom dimensions and impairment. However, little is known about the combined influence of these appraisals in OCD. A clear understanding of these relationships has putative treatment implications.

Aim:

The aim of the study is to examine the associations among obsessive beliefs, emotional appraisals, and OCD symptom dimensions in adults.

Materials and Methods:

We examined 50 drug-naïve/drug-free adults with active OCD. Symptom dimensions and impairment were assessed using the Dimensional Yale–Brown Obsessive–Compulsive Severity Scale. Obsessive beliefs and emotional appraisals were studied using the Obsessive Beliefs Questionnaire-44 and Perception of Threat from Emotion Questionnaire.

Results:

Tobit regression analysis showed the differential association of obsessive beliefs and symptom dimensions – perfectionism/certainty associated with contamination and responsibility/threat estimation associated with aggressive obsessions. Impairment was associated with dimensional symptom severities and with the perception of threat from anger. This association remained even after controlling for depression severity and obsessive beliefs.

Conclusions:

OCD symptom dimensions are heterogeneous in underlying obsessive beliefs. Emotional appraisals contribute significantly to impairment alongside symptom severity. Emotion-focused interventions must be included in the psychotherapeutic interventions for OCD.
Diagnostic Accuracy and Agreement between Four Phenotypic Carbapenemase Detection Tests among Enterobacterales
Authors: Farooqui Fizza , Irfan Seema , Laiq Sidra M
Published: August 2021

Introduction:

Carbapenem-resistant Enterobacterales (CREs) are becoming increasingly popular as a cause of hospital-acquired infections that are difficult to treat and are frequently reported as causes of outbreaks in various hospitals. Conventional culturing techniques take at least 2 days to report a case as carbapenem resistant, and it is therefore important to detect such resistance mechanisms as early as possible.

Methods:

This study aimed to compare the diagnostic performance of Carba NP, modified Hodge test (MHT), ethylenediaminetetraacetic acid (EDTA) disk synergy test (DST), and the modified carbapenem inactivation method (mCIM). This study was done at Microbiology Laboratory, Aga Khan University Hospital, Karachi. It was an observational study. Carba NP, MHT, EDTA DST, and the mCIM were performed on consecutive isolates of Enterobacterales. Sensitivity, specificity, and agreement between the four tests were calculated.

Results:

Of 207 Enterobacterales isolated, 127 were resistant to carbapenems. One hundred and fourteen of these were tested by a polymerase chain reaction, and the sensitivities of the Carba NP, MHT, EDTA DST, and the mCIM were found to be 94.34%, 75.47%, 79.25%, and 98.11%, respectively.

Conclusions:

Due to increased rates of carbapenem resistance, there is a need to employ mechanisms in hospitals that can identify such organisms as early as possible, both from clinical and epidemiological standpoints. The Carba NP test is a rapid, cost–effective, and reliable method and mCIM is more accurate but time consuming and both can be safely used for the screening of CREs.

Published: August 2021

Facial nerve palsy is the most frequent acute mononeuropathy and it is often of viral etiology, although many other causes have been identified. It has recently been described as a potential manifestation of COVID-19. We report the case of a patient with recent history of diarrhea and malaise that was admitted to the hospital presenting right facial paresis with orbicular muscle involvement. Nasopharyngeal swab tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on the real-time reverse transcription polymerase chain reaction and magnetic resonance imaging showed no structural changes. During the hospital stay, the patient showed clinical improvement, and no other symptoms were observed. This case presentation suggests a possible association between neuropathies and SARS-CoV-2 infection.

Published: August 2021

Since its discovery in 1953, the presence of the antigen Diego (Di) has been related to the Mongoloid populations and American natives. Given its immunogenic potential, the presence of the mentioned antigen is related to the development of hemolytic disease of the newborn (HDN). We present the case of a puerperal patient with no known history who was detected the presence of antibodies to Di b during study of a mild HDN presented by her daughter. When studying the patient's family, the presence of Dib antigen was reported in a brother as well as in both parents. We consider that being a rare event, this type of case should be reported promptly to promote the exchange of knowledge with other health professionals and the community.

Authors: Acharya Ashish , Bind Ravindra Kumar , Grewal Sarvpreet Singh , John Paul Sudhakar
Published: August 2021

Spontaneous spinal extradural hematomas are rarely attributed to hemophilia. When it occurs, magnetic resonance imaging (MRI) best establishes the diagnosis that should prompt immediate medical or surgical management. Here, we present a case with large spinal epidural hematomas (EDH) which was managed conservatively with good neurological outcome. A 12-year-old male who is a known case of hemophilia A was admitted with a complaint of neck pain, was neurologically intact on examination with no motor or sensory deficits. MRI cervical spine revealed a large spinal EDH in the cervical region compressing the cord posteriorly. The patient was managed conservatively with tranexamic acid and factor VIII replacement and observed over few days. He recovered well with interval resolution of hematoma. this case depicts the role of conservative management of spontaneous EDH in patients with Hemophilia A utilizing factor replacement therapy, steroids, and tranexamic acid and emphasizes that surgery is not always required even in such radiologically large appearing lesions.

Authors: Rajalakshmi B R , Basavaraj Vijaya
Published: August 2021

Systemic mastocytosis (SM) characterized by focal or diffuse infiltrates of neoplastic mast cells can range from indolent cutaneous disease to aggressive systemic disease. Skin involvement is usual in indolent systemic mastocytosis, less frequent in aggressive SM, and rare in mast cell leukemia. Here, we present a rare coexistence of cutaneous mastocytosis and SM with an associated hematologic neoplasm SM-associated hematologic neoplasm [AHN] (atypical chronic myeloid leukemia [CML]-BCR/ABL negative), the first case being reported in the literature so far to the best of our knowledge. An elderly male with leukocytosis, myeloid hyperplasia, and mast cell infiltrates in the marrow was diagnosed with atypical CML and cutaneous mastocytosis. Approximately 40% of cases of SM are associated with a hematologic neoplasm (SM-AHN) encompassing all defined myeloid neoplasms, such as myelodysplastic syndrome, myeloproliferative neoplasm, acute myeloid leukemia, CML, chronic myelomonocytic leukemia, or plasma cell myeloma. The prognosis of SM-AHN is dependent on the associated hematologic neoplasm (AHN).

Authors: AlSaleh Khalid
Published: August 2021

BACKGROUND:

Coronavirus disease 2019 (COVID-19) pandemic has caused disruption of oncology services, but data on actual delays are lacking. We sought to study the delays faced by the cancer patients during the COVID-19 pandemic and the impact of measures carried out to reduce the delays.

METHODS:

We carried out a review of inpatient and outpatient oncology services from March 15 to June 15, 2020, at our institution. We obtained data on delays in referrals, diagnosis, chemotherapy, and treatment delivery for cancer patients. To examine the delays, patients were assessed in the inpatient and outpatient settings and according to cancer types.

RESULTS:

A total of 505 patients' events were included in the study, with 136 referral delays, 167 diagnostic delays, 121 chemotherapy delays, and 81 treatment delays. In the outpatient settings, maximum referral delays were faced by breast cancer patients (9.5 ± 3.3 days, range 7–14), followed by hematologic malignancy (hematology) patients (8.4 ± 4.5 days, range 0–14). Maximum diagnosis delay was faced by hematology patients (11.75 ± 5 days, range 0–14), followed by breast cancer patients (11.2 ± 3.4 days, range 7–14). Breast and colorectal cancer patients faced maximum chemotherapy delays (9.5 ± 6.6 days, range 0–14), followed by hematology patients (7.3 ± 6.6 days, range 0–14). In the inpatient setting, maximum diagnosis delays were faced by hematology patients (11 ± 2 days, range 10–14), followed by gastrointestinal cancers (8 ± 2.4 days, range 5–10). Maximum chemotherapy delays were faced by hematology patients (8.5 ± 5.9 days, range 0–14) and breast cancer patients (8 ± 2.4 days, range 5–10). Hematology patients were most affected by treatment-delays (6.75 ± 4.7 days, range 0–10). Comparison of delays during the earlier part of the study with the later part showed that referral delays improved by 3.5 days (P = 0.02), diagnosis delays improved by 6.1 days (P < 0.001), chemotherapy delays improved by 7.7 days (P < 0.001), and treatment delays improved by 8 days (P < 0.001).

CONCLUSIONS:

COVID-19 pandemic caused delays in the diagnosis and management of most cancer patients. Measures adopted to overcome delays resulted in a significant reduction in delays.

Authors: Lestari Widya , Adanan Nurliyana Afiqah , Mokhtar Nur Izzati Attiyah , Ardini Yunita Dewi , Ichwan Solachuddin Jauhari Arief , Haris Muhammad Salahuddin
Published: August 2021

Introduction:

Monozygotic (MZ) twins share the same DNA, placenta, amniotic fluid, and physical features. Genetic factors play a prominent role compared to environmental factors in one’s physical appearance, including dental morphology. Here we studied variation in MZ twin’s tooth morphometry and palatal rugae pattern.

Materials and methods:

Variation between twins can be a valuable tool in forensics to identify individuals. Ten pairs of MZ twins were selected for this research. The maximum coronal mesiodistal and buccopalatal dimension of the maxillary teeth, excluding the second and third molars, were measured in triplicate using calipers. Palatal rugae patterns of the samples were cast, analyzed, and recorded based on shape and unification.

Results:

Our results showed a significant tooth dimension correlation between MZ twins. Maxillary central incisors had the least genetic variability, but the Carabelli trait, skeletal pattern, occlusion, and occlusal features all exhibited a greater correlation in MZ twins. Our findings provide compelling evidence for mirroring of dental features and palatal rugae patterns in MZ twins. This study is the first of its kind reported in Malaysia.

Conclusion:

Marked similarities in tooth morphometry and other dental physical features were observed between twins, which can be a useful tool in forensics for the identification of individuals.

Authors: Ahmed Junaid , Nath Mandovi , Sujir Nanditha , Shenoy Nandita , Ongole Ravikiran , Binnal Almas
Published: August 2021

Introduction:

Temporomandibular joint disorders (TMDs) involve abnormalities of either the disc or associated muscular structure. Evidence continues to accumulate regarding the untreated diseases of stomatognathic system, in particular, malocclusion and TMDs, which eventually carry a risk of development of postural disorders. The present study was undertaken to assess the correlation between TMDs and altered cervical range of motion and to review its association with the myogenous causes of TMD.

Materials and Methods:

A total of 80 patients were recruited and were divided into two groups; those diagnosed with TMDs were classified as cases and those who did not suffer from TMDs and/or cervical spine anomalies were classified as controls. Patients reporting with a positive history of painful joints and muscles were examined and were later referred to the department of physiotherapy, where the cervical range of motion was assessed using Baseline® bubble inclinometer. Cervical range of motion in healthy patients was compared with those affected with TMDs using posthoc Tukey test.

Results:

There was a significant difference in the values for range of motion and was found to be considerably restricted among the TMD subjects. Disability for the range of motion was statistically significant with a P-value of <0.001 for tests of active flexion, passive flexion, left active flexion, and left passive flexion in patients with myogenous TMDs.

Conclusion:

TMDs were found to be a significant factor in the occurrence of an impaired cervical range of motion.
Antifungal Efficacy of Wrightia tinctoria (Roxb.) R.Br on Candida Species Isolated from the Oral Cavity
Authors: Devika K.V. , Sabarinathan T. , Shamala S.
Published: August 2021

Introduction:

Nature is a valuable source of active ingredients that needs to be explored, especially its utilization in the medical field. Owing to the limited availability of antifungal drugs and also considering their side effects, there is always a constant need for a safe and competent alternative. Wrightia tinctoria, a medicinal tree, has been reported to possess potent antifungal activity against commercially available candida strains [American type culture collection (ATCC) and microbial type culture collection (MTCC)]. This could be beneficial clinically only if its antifungal activity could be proved against candida species isolated from clinical samples as the commercially available candida strains might have lost its pathophysiological characteristics on repeated subcultures. Hence, with this background, we performed this study to determine the antifungal efficacy of the extracts obtained from the leaves of W. tinctoria against the candida species isolated from the oral cavity. The aim of this study was to determine the antifungal efficacy of W. tinctoria on candida species isolated from the oral cavity.

Materials and Methods:

To determine the antifungal activity, acetone, ethyl acetate, and chloroform extracts of leaves of W. tinctoria were used. The study population consisted of five healthy volunteers above 18 years of age without any harmful habits and five patients at increased risk of candida infection. Saliva samples were collected by oral rinse technique using phosphate buffered saline. Fluconazole was used as a positive control and the antifungal efficacy was determined using disk diffusion method. Kruskal-Wallis test was used to determine the significant difference between the extracts.

Results:

The mean zone of inhibition of acetone, ethyl acetate, and chloroform extracts of leaves of W. tinctoria was 10.8667, 11.0000, 10.1333 mm, respectively.

Conclusion:

Acetone, ethyl acetate, and chloroform extracts of W. tinctoria possess antifungal activity against candida species isolated from oral cavity.

Authors: Munhoz Luciana , Haddad Denise S. , Arita Emiko S.
Published: August 2021

Introduction:

Saliva is a reservoir for biologic indicators and has a diverse microflora, which is critical particularly for coronavirus disease 2019 (COVID-19) transmission. Notwithstanding, saliva also could be applied as a noninvasive method to COVID-19 diagnosis and disease evolution monitoring. The objective of this systematic review is to summarize the main findings regarding to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection repercussion in saliva and/or salivary glands, addressing the following questions: What has been published regarding to the presence and implications of COVID-19 in saliva or salivary glands? and What are the researchers’ main results and conclusions?.

Materials and Methods:

A total of 31 published articles were included (27 research articles and 4 case reports). PubMed, Embase, Scopus, Web of Science, and Google Scholar databases were searched till August 2020. The terms COVID-19, novel coronavirus, and SARS-CoV-2 were combined with the keywords salivary gland, saliva, sialadenitis, parotid gland, sublingual gland submandibular gland, salivary gland disease, and minor salivary gland using the Boolean operator “AND.”

Results:

In this study, researchers’ main results and conclusions were exposed in tables. The main subjects of the articles were detection and viral load of SARS-CoV-2 in saliva, the influence of mouthwashes in SARS-CoV-2, and the presence of SARS-CoV-2 in aerosols.

Conclusion:

Although deep throat saliva may be used as a diagnostic tool to SAR-CoV-2 diagnosis, researchers found that the viral load in saliva is lower than in respiratory secretions.

Oral reactive lesions are relatively common. Collagen is the basic component of such overgrowths that could be fibrous or inflammatory. Hence, understanding the type, nature, and distribution of collagen fibers can aid in our knowledge and better management of these lesions.

Materials and Methods:

Ten paraffin blocks of each of the following lesions − giant-cell granuloma (L1), inflammatory fibrous hyperplasia (L2), pyogenic granuloma (L3), fibroma (L4), and peripheral ossifying fibroma (L5) − were retrieved from the archives. They were analyzed for their collagen birefringence property under polarized microscopy after picrosirius red stain. The demographic details of all the cases were recorded and evaluated.

Results:

In our study, giant-cell granulomas were commonly observed between third and seventh decades of life, inflammatory fibrous hyperplasias between second and fifth decades of life, yogenic granulomas in sixth decade, fibromas in fifth and sixth decades, and peripheral ossifying fibromas in second and fourth decade of life. All the lesions were predominant in females and commonly observed on gingiva. L5 lesions showed more areas of green birefringence followed by L1, L2, and L3 groups of lesions showed more of red birefringence than other lesions. Mixed birefringence of orange-red and green-yellow was almost same in all the lesions. All these findings were significant statistically.

Conclusion:

A plausible conclusion that the lesions with mature red fibers have better prognosis than the lesions with immature green fibers, in reactive oral lesions could be drawn.

Introduction:

Temporomandibular disorders (TMDs) are the main source of orofacial pain of nondental origin. Density changes in mandibular condyles of patients with TMD have not been well documented. The aim of this study was to compare condylar head bone density values in patient with and without TMD in cone-beam computed tomographic (CBCT) images.

Materials and Methods:

CBCT images of 70 patients with TMD and 70 age- and sex-controlled individuals were studied. Density of the cancellous bone in the left and right condylar heads was measured on a CBCT slice with the widest mediolateral dimension. Moreover, absence of at least one maxillary or mandibular posterior tooth (except for third molars) was recorded. Interclass correlation, t test, and Chi-squared test were used for statistical analysis.

Results:

Bone density in the condylar head significantly increased in patients with TMD compared with the non-TMD group (P < 0.001). The difference between males and females in each group was not significant (P = 0.182). Condylar head bone density in patients with TMD with posterior missing teeth was significantly less than individuals without missing teeth (P = 0.002).

Conclusion:

Increased density of condylar head must be regarded as a potential diagnostic tool for TMD when interpreting CBCT images of the joints.
Crystal ball gazing: where next for UK competition law and policy post-Brexit?

The Trade and Cooperation Agreement broadly sets out the nature of the relationship contemplated between UK and EU competition law and policy following Brexit. The question is whether the UK will capitalize on its newfound discretion to deviate its competition policy from the EU in the future. This article considers some of the potential new directions that might be taken within the UK's competition law landscape, specifically in relation to merger control, antitrust and subsidy control. It explores some of the problems and opportunities created in the wake of Brexit, as well as the legal and practical ramifications of future divergences between UK and EU competition policy. Furthermore, it considers how the Competition and Markets Authority may fare in enforcing new policy, as well as its potential interactions with regimes both within and outside the EU.

Objectives: The aim of this study was to evaluate the patient’s perception of the use of biological disease-modifying anti-rheumatic drugs (bDMARDs) and provide a basis for physicians to understand the patient’s perspective.

Patients and methods: Between December 2018 and June 2019, a total of 307 patients (162 males, 145 females; mean age: 48 years; range, 18 to 81 years) were included in this investigator-initiated, multi-center, observational, and cross-sectional study in six rheumatology centers. We asked patients using bDMARDs to treat rheumatoid arthritis (RA) or ankylosing spondylitis (AS) to complete a questionnaire regarding major considerations and satisfaction with bDMARDs, preferred administration route, knowledge about bDMARDs, experiences of adverse events, non-adherence, and expectations of their healthcare provider. The satisfaction of physician and clinical information on the patient's disease and treatment were also collected.

Results: Of the patients, 139 had RA and 168 had AS. Median disease duration was six years in RA and five years in AS. A total of 80.1% of the patients and 77.1% of the physicians indicated being satisfied or very satisfied with the therapeutic effect of the current bDMARD. Most patients were open to intravenous or subcutaneous injection, with the most preferred route of administration being subcutaneous (41.3%), followed by intravenous (32.0%), and oral (26.7%). The patients considered therapeutic effect to be more important than cost or convenience while choosing a bDMARD (69.3%), and most were willing to be educated about therapeutic effects (46.1%). Only 35.2% of the patients reported well and/or very well knowledge about the therapeutic effects, side effects, and administration methods of their current bDMARD, and 86.6% cited their physician as the primary source of information about biological treatment.

Conclusion: Patients value therapeutic effect more than cost or convenience while selecting a bDMARD, and consider their physicians to be the primary information source. Therefore, it is important for physicians to provide appropriate education and encourage patients to cooperate actively with treatment.

Each region certainly has its own past stories in the early church. In this case, the individual or group begins to remember something that happened in themselves and he can do memory activities while talking, listening and many other ways of remembering. Congregations in the current era, in understanding the meaning of togetherness in allied life, have begun to erode and fade. The purpose of this study is to describe the collective memory heritage of the congregation and to develop a counselling approach to promote congregational development. This study uses a qualitative approach with a descriptive-analytical pattern. From the results of the research, the authors see that the church today is in dire need of counselling assistance in church development. The integrity of a congregation is highly expected for every individual and group through fellowship that is carried out within the scope of the church and society in increasing harmonious and peaceful life. AbstrakSetiap daerah tentu memiliki cerita-cerita masa lalu tersendiri pada jemaat mula-mula. Dalam hal ini, individu atau kelompok mulai mengingat-ingat sesuatu yang terjadi dalam diri pribadinya dan ia dapat melakukan aktivitas mengingat-ingat ketika sedang berbicara, mendengarkan dan masih banyak lagi cara mengingat-ingat lainnya. Jemaat di era saat ini, dalam memahami arti kebersamaan dalam hidup bersekutu sudah mulai terkikis dan memudar. Tujuan penelitian ini untuk mendeskripsikan warisan memori kolektif jemaat Adang dan mengembangkan pendekatan konseling untuk meningkatkan pembangunan jemaat Adang. Penelitian ini menggunakan metode pendekatan kualitatif dengan pola deskriptif-analitis. Dari hasil penelitian penulis melihat bahwa jemaat Adang saat ini sangat membutuhkan pendampingan konseling dalam pembangunan jemaat. Keutuhan suatu jemaat sangat di harapkan bagi setiap individu maupun kelompok melalui persekutuan yang dilakukan dalam lingkup gereja maupun masyarakat dalam meningkatkan hidup rukun dan damai.
