Abstract
Background As there is no consensus on the optimal surgery strategy for multiple primary lung cancer (MPLC), we conducted this study to address this issue by comparing the prognosis of MPLC patients underwent different surgical strategies including sublobar resection and the standard resection through a systemic review and meta-analysis. Methods Relevant literature was obtained from three databases including PubMed, Embase and Web of Science. Inclusion and exclusion criteria were set for the screening of articles to be selected for further conduction of systemic review and meta-analysis. The HRs of OS of the sublobar group compared with standard resection group were extracted directly or calculated indirectly from included researches. Result s: Ten researches published from 2000 to 2017 were included in this study, with 468 and 445 MPLC cases for the standard resection group and sublobar resection group respectively. The result suggested that OS of MPLC patients underwent sublobar resection (segmentectomy or wedge resection for at least one lesion) was comparable with those underwent standard resection approach (lobectomy or pneumonectomy for all lesions), with HR 1.07, 95% CI 0.67 - 1.71, p = 0.784. Further analysis found no difference in subgroups of synchronous and metachronous (from second metachronous lesion), different population region and dominant sex type. Conclusions This study may reveal that sublobar resection is acceptable for patients with MPLC at an early stage, because of the equivalent prognosis to the standard resection and better pulmonary function preservation. Further research is needed to validate these findings.

Abstract
The occurrence of segmental/lobar pattern pneumonia in children increases with years recently. The pathogens of the disease may change for the abuse of antibiotics and the application of pneumococal vaccines. The pathogens of segmental/lobar pattern pneumonia in hospitalized children and their association with clinical characteristics are poorly understood nowadays. The current study retrospectively analyzed the pathogens and clinical characteristics of segmental/lobar pattern pneumonia in children at a single hospital between 1 st Jan 2014 and 31 st Dec 2018. The pathogens and their associations with clinical characteristics were statistically analyzed. A total of 593 children with segmental/lobar pattern pneumonia received treatment at a single hospital during the study period. 451 patients were positive for one pathogen and 83 patients were positive for two pathogens or more. Mycoplasma pneumoniae (M.pneumoniae) (72.34%) was the most commonly detected pathogen, followed by streptococcus pneumoniae (S.pneumoniae) (8.77%). The infection of M.pneumoniae in children with segmental/lobar pattern pneumonia increased with years (p<0.05). The positive rate of M.pneumoniae increased with ages of patients (p<0.05). M.pneumoniae was statistically associated to the extrapulmonary manifestations while S.pneumoniae was statistically associated with abnormal WBCs and CRPs (p<0.05). In a summary, M.pneumoniae was the most positive pathogen of segmental/lobar pattern pneumonia in hospitalized children. The positive rate of M.pneumoniae in children with segmental/lobar pattern pneumonia increased with years and the ages of children. M.pneumoniae was associated with extrapulmonary manifestations while S.pneumoniae was associated with abnormal WBCs and CRPs.

Cucumber (Cucumis sativus Linnaeus, 1753) stands out in the Brazilian agribusiness of vegetables as it can be consumed in salads (in natura or pickled) or even used for the production of cosmetics and drugs. During cucumber cultivation, several insectpests, mainly from the Orders Hemiptera, Thysanoptera, Lepidoptera, can cause significant yield losses. Therefore, this study aimed to evaluate the entomofaunistic diversity of arthropods in cucumber crop using Moericke and Pitfall traps. Cucumber seedlings were commercially obtained and grown up in the experimental area of the Federal University of Fronteira Sul – Campus Chapecó (SC). Three samplings were carried out between October and December, 2015. The sampled specimens were identified to the taxon of Order and placed in vials containing alcohol solution (70%). A total of 1.651 specimens were identified and classified into 11 different Orders. Pitfall traps sampled a greater number of orders (9) and specimens (1.309), with emphasis to the Order Hymenoptera (928). For the aerial traps (Moericke), 342 specimens, allocated in eight different Orders, were identified, with the Order Diptera as the most abundant one (153 individuals). Moericke and Pitfall traps showed a Shannon-Weaver diversity index of 1.53 and 1.02, respectively.

Published: August 2019

Introduction: The loss of retention of prefabricated fiber pins is a relatively frequent clinical complication. Different techniques for cementation have been studied and developed in order to reduce the chances of failure. In this context, the technique that uses a sonic vibration for cementing fiber pins appears. Objective: To evaluate by scanning electron microscopy (SEM) the sonic vibration effect on the cementation line between fiberglass pins and root dentin in bovine roots. Material and methods: Roots of bovine incisors wereendodontically treated and randomly distributed into four groups: SVS (conventional application of the system and cement), VSA (sonic application of adhesive system + conventional application of cement), VSP (conventional application of the information system + sonic application of cement) and VSAP (sonic application of the information system + sonic application of cement). Subsequently, slices of each root were obtained, corresponding to the cervical,middle and apical thirds. The slices were submitted to SEM analysis to evaluate the cementation line, verifying distribution and size of defects, considering three different locations: cement/pine interface (CP); internal layer of cement (LC); cement/dentin interface (CD). Results: An analysis of the results allowed to verify the incidence of minor faults in the apical region and suffered a gradual increase from apical to cervical in all the studied groups. Regardless of theused technique the greatest absolute number of defects was in the cement/dentin interface. Conclusion: The application and assembly technique can influence the characteristics of the cementation line between the fiberglass pin and dentine walls of the root canal.

Introduction: The coronary shield, known as the intra-orifice barrier, is defined as a placement of a restorative material at the entrance of the root canal orifice after 3mm of gutta-percha and aiming to increase the resistance of the tooth to the fracture in addition to preventing coronary infiltration. Objective: to report and discuss the existing data in the dental literature regarding the materials available to perform the intra-orifice barrier in endodontically treated teethand to indicate if the desired coronary shield is really achievable. Literature review: The materials analyzed were composite resin, glass ionomer cement (CIV), zinc oxide based materials, silver amalgam and mineral trioxide aggregate (MTA). Results: composites of resin and bulkfill / flow in their results when compared with other materials like MTA. Silver amalgam, zinc oxide-based materials, and CIV do not result in terms of intra-orifice barrier. MTA was favorable in relation to microleakage, but did not reinforce a root structure. Conclusion: No material restorer is able to completely protect the infiltrations.However, as conventional composite resins and bulk-fill flow are the materials with the best properties associated with satisfactory results, however, the need for scientific studies comparing the materials used as an intra-orifice barrier.

Introduction and objective: The oral health of patients with HIV infection is often compromised by caries and periodontal disease. Thus, many patients need to undergo oral surgical procedures. Case report: This article describes two cases of patients with HIV infection who had undergone exodontia due to prosthetic indications. Both patients had been hospitalized for treatment of respiratory complications from HIV infection and were referred for dental treatment. In the first case, the adult patient had generally good oral health. However, the treatment plan for the installation of a removable prosthesis required the removal of tooth 38 since it was fairly inclined to the mesial. The second patient had poor oral conditions due to advanced periodontal disease. Thus, all upper arch teeth were removed in a single session followed by the installationof an immediate total prosthesis. No postoperative complications were recorded and the healing process occurred without incident for both patients. Dental treatment of patients with asymptomatic HIV infection does not differ from that performed for any other patient in practice. Nevertheless, patients in advanced stages of disease may require special treatment and an individual treatment plan must be developed for even routine procedures. Conclusion: The dental careof these individuals often requires more rigorous clinical follow-up for maintaining oral health. The performance of dental surgery in patients with HIV infection does not require technical modifications, but does require a complete anamnesis.

Published: August 2019

Background:Particulate Hydroxyapatite (HAP; Ca5(PO4)3(OH)) is being increasingly used as multifunctional active ingredient in oral care. Due to its high similarity to human enamel crystallites, it is considered as a biomimetic agent.Objective:The aim of this narrative review is to identify the modes of action of HAP in preventive oral health care based on published studies. The outcomes are expected to improve the understanding of the effects of HAP in the oral cavity and to provide a knowledge base for future research in the field of biomimetic oral care.Methods:The data analyzed and discussed are primarily based on selected published scientific studies and reviews fromin vivo,in situ, andin vitrostudies on HAP in the field of preventive oral health care. The databases Cochrane Library, EBSCO, PubMed and SciFinder were used for literature search.Results:We identified different modes of action of HAP in the oral cavity. They are mainly based on (I) Physical principles (e.g. attachment of HAP-particles to the tooth surface and cleaning properties), (II) Bio-chemical principles (e.g. source of calcium and phosphate ions under acidic conditions and formation of an interface between HAP-particles and the enamel), and (III) Biological principles (e.g. HAP-particles interacting with microorganisms).Conclusion:Although more mechanistic studies are needed, published data show that HAP has multiple modes of action in the oral cavity. Since the effects address a wide range of oral health problems, HAP is a biomimetic agent with a broad range of applications in preventive oral health care.

Purpose:This study sought to identify the magnitude and the possible risk factors of ocular complications in patients with Obstructive Sleep Apnea (OSA).Methods:A hospital-based cross-sectional study with a nested case-control design was conducted. Qualifying study subjects were patients who had been diagnosed with moderate to severe OSA (AHI index of ≥ 5, n=80), and control subjects (n=20) who had an AHI index of ≤ 5 (“normal”). Study participants were recruited from Mansoura University Hospital’s Sleep Disorders Clinic in Mansoura, Egypt.Selected subjects were assessed for ocular complications at Mansoura Univerity Hospital Ophthalmic Center, (Mansoura), Egypt. An ophthalmic history was recorded, and opthalmic testing was carried out. The testing included unaided visual acuity measurement, refraction, best-corrected visual acuity measurement, slit lamp bio-microscopic evaluation of the anterior segment and anterior segment photography, dilated fundus examination, intraocular pressure measurement, fundus photo, and fluorescein angiography, and visual field assessment. Various tests of OSA symptoms were also monitored, including the AHI, lowest oxygen concentrations and desaturation index plus the overall severity index. .Results:It was found that OSA patients n=28 (35%), n=24 (30%), n=4 (5%) had senile cataract, normal tension glaucoma, and retinal ischemia, respectively, with an overall prevalence of 45%. Additionally, the OSA group had seven times greater risk (OR=7.36, 95%CI: 1.6-33.86) of vision-threatening disorders compared to the controls. OSA patients were observed to be at a greater risk of senile cataract 28 (35%), normal tension glaucoma 24 (30%), retinal ischemia 4 (5%) and conjunctival hyperemia and dry eye (OR=3.77, 95%CI: 1.02-13.95, OR=4.36, 95%CI: 1.26-17.08). Also, multivariate logistic regression analysis testing showed that the lowest oxygen saturation index was the only significant predictor negatively associated with vision-threatening disorders (OR=0.84, 95%CI: 0.75-0.93).Conclusion:The risk of vision-threatening and non-threatening ocular disorders is higher among OSA cases. The lowest oxygen saturation index was the only significant predictor of vision-threatening disorders. These findings support the recommendation that a full ophthalmic examination should be carried out on patients with confirmed OSA.

Objective:
This paper presents the design and simulation of double bridge-type capacitive
RF MEMS switch by using FEM Tool.

Methods:
It is mainly concentrated on a low pull-in voltage, capacitance, and RF analysis. The beam is
considered as a gold metal having the length of 595 μm along with the 1μm thickness and the dielectric
is taken as Silicon nitride (Si3N4) by using Ashby’s method. The non-uniform meandering technique
and perforations are used to reduce the pull-in voltage, by changing different beam thickness, air
gap and materials.

Results:
The pull-in voltage of the proposed RF MEMS switch is 1.2 V. The scattering parameters are
simulated by using Ansoft HFSS software. The simulation results of S-parameters such as return loss,
insertion losses are, -19.27 dB and -0.20dB. The switch having good isolation is -63.94 dB at 8 GHz.

Conclusion:
The overall switch is designed with different beam thickness, various gap, and different
materials to identify the best performance of the switch for low-frequency applications i.e X-bands.

Published: August 2019

Background and Objective:
The objectives of this study were to investigate the
effects of land use and land cover transitions on soil physico-chemical properties, and to
comparatively study soil microbial activity in ecological restoration red soil region of subtropical
southern China.

Methods:
A field experiment was conducted in a natural forest, four ecological restoration
forests and an adjacent farmland. Based on the stable carbon isotopes of SOM, the δ13C values
data confirm the 6 sites for soil sampling in this study were the ideal location for studying
land cover transitions. The data showed that the soil physical, chemical and biological
properties under the natural forest were significantly healthier than under cultivation. During
forest re-growth on farmland, the ecological restoration time were 34, 26, 15 and 10a, respectively,
and the SOM content, C/N, soil colony counts, soil basal respiration and soil enzyme
activities significantly increased and approached values of virgin forest.

Results & Conclusion:
In general, the SOM content and soil microbial activities in ecological
restoration forest were usually intermediate between the natural forest and farmland, and
there was significant (P< 0.05) difference between forest and farmland. The results indicated
that, because of appropriate climatic conditions of red soil subtropical southern China, the
dynamic balance of soil ecosystems can be reconstructed and restored in several years or
decades.

Background
The use of apps to tackle overweight and obesity by tracking physical and dietary patterns and providing recommendations and motivation strategies to achieve personalized goals has increased over recent years. However, evidence of the efficacy, effectiveness, and safety of these apps is severely lacking.

Objective
The aim of this study was to identify efficacy, safety, and effectiveness criteria used to assess weight control, overweight, and obesity management in mobile health (mHealth) interventions through a systematic review.

Methods
PubMed, PsycINFO, Scopus, UK Trial Database, ClinicalTrials.gov, and the Cochrane Library were surveyed up to May 2018. All types of clinical studies were considered. A total of 2 independent reviewers assessed quality using Scottish Intercollegiate Guidelines Network (SIGN) criteria. Ratings were used to provide an overall score for each study (low, moderate, or high). Data were synthesized in evidence tables.

Results
From 233 potentially relevant publications, only 28 studies were included. Of these, 13 (46%) were randomized control trials, 11 were single-arm studies (39%), 3 were nonrandomized controlled trials (11%), and 1 study was a cluster randomized trial (4%). The studies were classified as low (15), high (7), and moderate (6) quality according to SIGN criteria. All studies focused on efficacy, with only 1 trial mentioning safety and another 1 effectiveness. In 11 studies, the apps were used as stand-alone interventions, the others were multicomponent studies that included other tools for support such as sensors or websites. The main management tool included in the apps was feedback messaging (24), followed by goal-setting mechanisms (20) and self-monitoring (19). The majority of studies took weight or body mass index loss as the main outcome (22) followed by changes in physical activity (14) and diet (12). Regarding outputs, usability, adherence, and engagement (17) were the most reported, followed by satisfaction (7) and acceptability (4).

Conclusions
There is a remarkable heterogeneity among these studies and the majority have methodological limitations that leave considerable room for improvement. Further research is required to identify all relevant criteria for assessing the efficacy of mHealth interventions in the management of overweight and obesity.
