[PMID: 38537496 DOI: 10.1016/j.puhe.2024.01.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 01/13/2024] [Accepted: 01/29/2024] [Indexed: 04/16/2024]
Abstract
OBJECTIVES Marburg virus, previously referred to as Marburg hemorrhagic fever, is a highly severe and frequently fatal illness that affects humans. This study aimed to develop and validate a French questionnaire to assess knowledge, attitude, and practice toward Marburg virus disease (FKAP-MVD). STUDY DESIGN An anonymous online survey was used, which was distributed through various platforms and emails. Data were collected from Burkina Faso, Guinea, the Democratic Republic of Congo, and Senegal. METHODS To conduct the study, an anonymous online survey was used, which was distributed through various platforms such as Facebook, Twitter, WhatsApp, and emails. The survey was uploaded onto a Google form to facilitate data collection. Data were collected from Burkina Faso, Guinea, the Democratic Republic of Congo, and Senegal. RESULTS Of the total sample of 510 participants, 60.0% were male, their mean age was 28.41 ± 6.32 years, 38.0% were married, 86.6% resided in urban areas and 64.1% had a university education. The questionnaire had good internal consistency; Cronbach's alpha was 0.87. The correlation between knowledge and attitude was 0.002, the correlation between knowledge and practice was 0.204, and the correlation between practice and attitude was relatively weak and negative at -0.060. This indicates the divergent validity of the questionnaire. The KMO value of 0.91 indicates a high level of adequacy, suggesting that the data are suitable for factor analysis. The Bartlett test of Sphericity yielded an approximate χ2 value of 4016.890 with 300 degrees of freedom and a P-value of 0.0001. The confirmatory factor analysis revealed 25 questions in three domains. The normed chi-square value is 1.224. The goodness of Fit Index (GFI) is 0.902, the Comparative Fit Index (CFI) is 0.982, the Root Mean Square Error of Approximation (RMSEA) is 0.033, and the Root Mean Square Residual (RMR) is 0.062. These values indicate a good fit of the model to the data. CONCLUSIONS In general, the developed questionnaire has significant potential to inform public health initiatives and interventions related to MVD.

Evaluation of monte carlo to support commissioning of the treatment planning system of new pencil beam scanning proton therapy facilities. Phys Med Biol 2024; 69:045027. [PMID: 38052092 DOI: 10.1088/1361-6560/ad1272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Accepted: 12/05/2023] [Indexed: 12/07/2023]
Abstract
Objective. To demonstrate the potential of Monte Carlo (MC) to support the resource-intensive measurements that comprise the commissioning of the treatment planning system (TPS) of new proton therapy facilities.Approach. Beam models of a pencil beam scanning system (Varian ProBeam) were developed in GATE (v8.2), Eclipse proton convolution superposition algorithm (v16.1, Varian Medical Systems) and RayStation MC (v12.0.100.0, RaySearch Laboratories), using the beam commissioning data. All models were first benchmarked against the same commissioning data and validated on seven spread-out Bragg peak (SOBP) plans. Then, we explored the use of MC to optimise dose calculation parameters, fully understand the performance and limitations of TPS in homogeneous fields and support the development of patient-specific quality assurance (PSQA) processes. We compared the dose calculations of the TPSs against measurements (DDTPSvs.Meas.) or GATE (DDTPSvs.GATE) for an extensive set of plans of varying complexity. This included homogeneous plans with varying field-size, range, width, and range-shifters (RSs) (n= 46) and PSQA plans for different anatomical sites (n= 11).Main results. The three beam models showed good agreement against the commissioning data, and dose differences of 3.5% and 5% were found for SOBP plans without and with RSs, respectively. DDTPSvs.Meas.and DDTPSvs.GATEwere correlated in most scenarios. In homogeneous fields the Pearson's correlation coefficient was 0.92 and 0.68 for Eclipse and RayStation, respectively. The standard deviation of the differences between GATE and measurements (±0.5% for homogeneous and ±0.8% for PSQA plans) was applied as tolerance when comparing TPSs with GATE. 72% and 60% of the plans were within the GATE predicted dose difference for both TPSs, for homogeneous and PSQA cases, respectively.Significance. Developing and validating a MC beam model early on into the commissioning of new proton therapy facilities can support the validation of the TPS and facilitate comprehensive investigation of its capabilities and limitations.

Abstract
OBJECTIVES Although headache is a common symptom in acute ischemic stroke, the clinical and radiological factors associated with its occurrence are controversial. This work aimed to determine the frequency, characteristics, and predictors of headache occurrence among patients with acute ischemic stroke. METHODS This cross-sectional study was conducted on 303 patients with acute ischemic stroke. The patients were submitted to detailed history taking, clinical and radiological assessment. A detailed analysis of headache was performed for the patients who experienced headache temporally related to stroke onset. RESULTS Diagnosis of headache attributed to the ischemic stroke was established in 129 (42.6%) patients; sentinel headache in 17.2% of patients, and headache at stroke onset in 25.4% of patients. The headache group had a significantly younger age (P=0.017), lower NIHSS score (P=0.042), higher frequency of pre-existing headache disorders (P=0.001), substance use disorder (P=0.021), and fever (P=0.036), and lower frequency of chronic hypertension (P=0.013) and small vessel disease (P=0.004) than non-headache group. Infarction involving posterior circulation was more frequent in headache than in non-headache groups (P=0.003). The presence of migraine, tension-type headache, other types of headache, fever and posterior circulation stroke increased the odds of headache by 27.4 (95%CI=8.0-94.4), 7.6 (95%CI=3.93-14.6), 26.2 (95%CI=8.0-85.8), 3.75 (95%CI=1.22-11.6) and 3.15 (95%CI=1.65-6.0) times, respectively, whereas, the presence of small vessel disease decreased the odds of headache by 0.51 (95%CI=0.279-0.95) times. CONCLUSION Pre-existing headache disorder, fever, and posterior circulation stroke were associated with headache occurrence in acute ischemic stroke patients.

Abstract
Objective. To report the use of a portable primary standard level graphite calorimeter for direct dose determination in clinical pencil beam scanning proton beams, which forms part of the recommendations of the proposed Institute of Physics and Engineering in Medicine (IPEM) Code of Practice (CoP) for proton therapy dosimetry.Approach. The primary standard proton calorimeter (PSPC) was developed at the National Physical Laboratory (NPL) and measurements were performed at four clinical proton therapy facilities that use pencil beam scanning for beam delivery. Correction factors for the presence of impurities and vacuum gaps were calculated and applied, as well as dose conversion factors to obtain dose to water. Measurements were performed in the middle of 10 × 10 × 10 cm3homogeneous dose volumes, centred at 10.0, 15.0 and 25.0 g·cm-2depth in water. The absorbed dose to water determined with the calorimeter was compared to the dose obtained using PTW Roos-type ionisation chambers calibrated in terms of absorbed dose to water in60Co applying the recommendations in the IAEA TRS-398 CoP.Main results.The relative dose difference between the two protocols varied between 0.4% and 2.1% depending on the facility. The reported overall uncertainty in the determination of absorbed dose to water using the calorimeter is 0.9% (k= 1), which corresponds to a significant reduction of uncertainty in comparison with the TRS-398 CoP (currently with an uncertainty equal or larger than 2.0% (k= 1) for proton beams).Significance. The establishment of a purpose-built primary standard and associated CoP will considerably reduce the uncertainty of the absorbed dose to water determination and ensure improved accuracy and consistency in the dose delivered to patients treated with proton therapy and bring proton reference dosimetry uncertainty in line with megavoltage photon radiotherapy.

Development of optimised tissue-equivalent materials for proton therapy. Phys Med Biol 2023; 68.

Abstract
Objective. In proton therapy there is a need for proton optimised tissue-equivalent materials as existing phantom materials can produce large uncertainties in the determination of absorbed dose and range measurements. The aim of this work is to develop and characterise optimised tissue-equivalent materials for proton therapy.Approach. A mathematical model was developed to enable the formulation of epoxy-resin based tissue-equivalent materials that are optimised for all relevant interactions of protons with matter, as well as photon interactions, which play a role in the acquisition of CT numbers. This model developed formulations for vertebra bone- and skeletal muscle-equivalent plastic materials. The tissue equivalence of these new materials and commercial bone- and muscle-equivalent plastic materials were theoretical compared against biological tissue compositions. The new materials were manufactured and characterised by their mass density, relative stopping power (RSP) measurements, and CT scans to evaluate their tissue-equivalence.Main results. Results showed that existing tissue-equivalent materials can produce large uncertainties in proton therapy dosimetry. In particular commercial bone materials showed to have a relative difference up to 8% for range. On the contrary, the best optimised formulations were shown to mimic their target human tissues within 1%-2% for the mass density and RSP. Furthermore, their CT-predicted RSP agreed within 1%-2% of the experimental RSP, confirming their suitability as clinical phantom materials.Significance. We have developed a tool for the formulation of tissue-equivalent materials optimised for proton dosimetry. Our model has enabled the development of proton optimised tissue-equivalent materials which perform better than existing tissue-equivalent materials. These new materials will enable the advancement of clinical proton phantoms for accurate proton dosimetry.

Challenges in modeling the Agility multileaf collimator in treatment planning systems and current needs for improvement. Med Phys 2022; 49:7404-7416. [PMID: 36217283 PMCID: PMC10092639 DOI: 10.1002/mp.16016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 08/22/2022] [Accepted: 09/12/2022] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND The Agility multileaf collimator (MLC) mounted in Elekta linear accelerators features some unique design characteristics, such as large leaf thickness, eccentric curvature at the leaf tip, and defocused leaf sides ('tilting'). These characteristics offer several advantages but modeling them in treatment planning systems (TPSs) is challenging. PURPOSE The goals of this study were to investigate the challenges faced when modeling the Agility in two commercial TPSs (Monaco and RayStation) and to explore how the implemented MLC models could be improved in the future. METHODS Four linear accelerators equipped with the Agility, located at different centers, were used for the study. Three centers use the RayStation TPS and the other one uses Monaco. For comparison purposes, data from four Varian linear accelerators with the Millennium 120 MLC were also included. Average doses measured with asynchronous sweeping gap tests were used to characterize and compare the characteristics of the Millennium and the Agility MLCs and to assess the MLC model in the TPSs. The FOURL test included in the ExpressQA package, provided by Elekta, was also used to evaluate the tongue-and-groove with radiochromic films. Finally, raytracing was used to investigate the impact of the MLC geometry and to understand the results obtained for each MLC. RESULTS The geometry of the Agility produces dosimetric effects associated with the rounded leaf end up to a distance 20 mm away from the leaf tip end measured at the isocenter plane. This affects the tongue-and-groove shadowing, which progressively increases along the distance to the tip end. The RayStation and Monaco TPSs did not account for this effect, which made trade-offs in the MLC parameters necessary and greatly varied the final MLC parameters used by different centers. Raytracing showed that these challenging leaf tip effects were directly related to the MLC geometry and that the characteristics mainly responsible for the large leaf tip effects of the Agility were its tilting design and its small source-to-collimator distance. CONCLUSIONS The MLC models implemented in RayStation and Monaco could not accurately reproduce the leaf tip effects for the Agility. Therefore, trade-offs are needed and the optimal MLC parameters are dependent on the specific characteristics of treatment plans. Refining the MLC models for the Agility to better approximate the measured leaf tip and tongue-and-groove effects would extend the validity of the MLC model, reduce the variability in the MLC parameters used by the community, and facilitate the standardization of the MLC configuration process.

Abstract
Abstract
Introduction
The BOAST guideline's standard of practise for the management of distal Radius Fractures states that assessment of circulation and sensation should be documented prior to and after MUA for distal radius fractures. We measured the compliance of the completion and documentation of the neurovascular assessment prior to and after Bier's Block for MUA of distal radius fractures.
Methods
We assessed electronic medical records of these patients during the period November/December 2020. Focusing on the completion of the neurovascular assessment and documentation prior to Bier's Block and compared the results to our first cycle audit done in July/August 2020 following our intervention.
Results
58 patients were analysed for this study compared to 50 in the initial study. 88% had neurovascular assessment done and documented in the Emergency Department compared to 98% in the initial study. However, 60.3% had documentation of neurovascular assessment prior to Bier's block compared to 34% previously. 39.7% had vascular assessment after Bier's block and 64% had neurovascular assessment done in fracture clinic in this second cycle compared to 22% and 76% for vascular assessment and Neurovascular assessment in the facture clinic respectively after the MUA.
Conclusion
This re- audit shows an improvement in the assessment and documentation of neurovascular Status prior to and following MUA of distal radius fracture. There is however a need for improvement. Suggested methods include teaching of upper limb neurological assessment to orthopaedic juniors, Aide memoire such as a small sticker to attach to the notes/ Stamp in the fracture clinic notes.
Take-home message
Assessing and documenting neurovascular status before and after an MUA is very important.

Abstract
Echinococcus granulosus causes Cystic Echinococcosis disease in intermediate hosts, such as sheep, cattle, goats, camels, and horses. Cystic Echinococcosis is an essential parasitic zoonosis that affects humans and animals and is a significant public health and economic problem worldwide. This study aimed to determine the molecular characterization and phylogenetic analysis of Echinococcus granulosus in sheep's livers and lungs. The genetic variation was performed by directly sequencing the mitochondrial DNA (mtDNA) genes coding of the NADH dehydrogenase subunit 1 (ND1). The evidence from molecular studies and DNA sequencing revealed that the Isolates of Echinococcus granulosus in Kirkuk city related to the sheep strain G1 genotype. The alignment analysis showed a concordance between isolates with each other by 99%. When comparing the results with Genbank, it indicated the occurrence of genetic variations between nucleotides represented by eleven codons, seven of which represent transversion mutations, and four are transition mutations.

Abstract
The mass of the W boson, a mediator of the weak force between elementary particles, is tightly constrained by the symmetries of the standard model of particle physics. The Higgs boson was the last missing component of the model. After observation of the Higgs boson, a measurement of the W boson mass provides a stringent test of the model. We measure the W boson mass, MW, using data corresponding to 8.8 inverse femtobarns of integrated luminosity collected in proton-antiproton collisions at a 1.96 tera-electron volt center-of-mass energy with the CDF II detector at the Fermilab Tevatron collider. A sample of approximately 4 million W boson candidates is used to obtain [Formula: see text], the precision of which exceeds that of all previous measurements combined (stat, statistical uncertainty; syst, systematic uncertainty; MeV, mega-electron volts; c, speed of light in a vacuum). This measurement is in significant tension with the standard model expectation.

Abstract
PURPOSE In particle therapy, determination of range by measurement or calculation can be a significant source of uncertainty. This work investigates the development of a bespoke Range Length Phantom (RaLPh) to allow independent determination of proton range in tissue. This phantom is intended to be used as an audit device. METHOD RaLPh was designed to be compact and allows different configurations of tissue substitute slabs, to facilitate measurement of range using radiochromic film. Fourteen RaLPh configurations were tested, using two types of proton fluence optimised water substitutes, two types of bone substitute, and one lung substitute slabs. These were designed to mimic different complex tissue interfaces. Experiments were performed using a 115 MeV mono-energetic scanning proton beam to investigate the proton range for each configuration. Validation of the measured film ranges was performed via Monte Carlo simulations and ionisation chamber measurements. The phantom was then assessed as an audit device, by comparing film measurements with Treatment Planning System (TPS) predicted ranges. RESULTS Varying the phantom slab configurations allowed for measurable range differences, and the best combinations of heterogeneous material gave agreement between film and Monte Carlo on average within 0.2% and on average within 0.3% of ionisation chamber measurements. Results against the TPS suggest a material density override is currently required to enable the phantom to be an audit device. CONCLUSION This study found that a heterogeneous phantom with radiochromic film can provide range verification as part of a dedicated audit for clinical proton therapy beams.

Abstract
To date, coronavirus disease 2019 (COVID-19) has affected over 6.2 million individuals worldwide, including 1.46 million deaths. COVID-19 complications are mainly induced by low-grade inflammation-causing vascular degeneration. There is an increasing body of evidence that suggests that oral dysbiotic taxa are associated with worse prognosis in COVID-19 patients, especially the Prevotella genus, which was retrieved from nasopharyngeal and bronchoalveolar lavage samples in affected patients. Oral dysbiosis may act by increasing the likelihood of vascular complications through low-grade inflammation, as well as impairing respiratory mucosal barrier mechanisms against SARS-CoV-2. Salivary markers can be used to reflect this oral dysbiosis and its subsequent damaging effects on and the lungs and vasculature. Salivary sampling can be self-collected, and is less costly and less invasive, and thus may be a superior option to serum markers in risk stratification of COVID-19 patients. Prospective studies are needed to confirm such hypothesis. Video Abstract: http://links.lww.com/CAEN/A28.

Abstract
Ever since the uncovering of the severe discrepancy of COVID-19 manifestations, irrespective of viral load, scientists have raced to locate and manage factors contributing to the genesis of a critical state. Recent evidence delineates the role of oral dysbiosis in the development of low-grade inflammation, characterized by the increase of inflammatory cytokines common to those fundamental to the development of severe COVID. Furthermore, high periodontopathic bacteria were recorded in severe acute respiratory syndrome in COVID patients, as well as its common provoking comorbidities such as diabetes and hypertension. This can be explained by the immigration and elimination of oral bacteria into the airways, which, in the context of an injured lung, allows for their preferential overgrowth familiar to that, causing the progression to advanced lung diseases. This is why we indicate the promising usage of oral microbiome transplantation as a treatment of oral microbial dysbiosis, not only associated with the worst outcomes of COVID-19 but also in other disorders of low-grade inflammation.

Abstract
Nanostructured semiconductor nanowires (NWs) present a smart solution for broadband absorption solar cells (SCs) with high efficiency and low-cost. In this paper, a novel design of quad crescent-shaped silicon NW SC is introduced and numerically studied. The suggested NW has quad crescent shapes which create a cavity between any adjacent NWs. Such a cavity will permit multiple light scattering with improved absorption. Additionally, new modes will be excited along the NWs, which are highly coupled with the incident light. Further, the surface reflection from the crescent NWs is decreased due to the reduced surface filling ratio. The finite difference time domain method is utilized to analyze the optical characteristics of the reported structure. The proposed NW offers short circuit current density (Jsc) of 27.8 mA/cm2 and ultimate efficiency (ηul) of 34% with an enhancement of 14% and volume reduction of 40% compared to the conventional NWs. The Jsc and ηul are improved to 35.8 mA/cm2 and 43.7% by adding a Si substrate and back reflector to the suggested crescent NWs.

Hypoxia-inducible factor (HIF): The link between obesity and COVID-19. ACTA ACUST UNITED AC 2020; 22:100317.

Abstract
The COVID-19 death toll has involved to date more than 1 million confirmed deaths. The death rate is even higher in the obese COVID-19 patients, as a result of hypoxia, due to the interplay between adipose tissue hypoxia and obstructive sleep apnea. The discrepancy of manifestations seen in COVID-19 seems to be mediated by a differential immune response rather than a differential viral load. One of the key players of the immune response is HIF. HIF-1β is a stable constitutively expressed protein in the nucleus; and under hypoxic changes, its activity is unaffected, whereas the HIF-α subunit has a short half-life and because of its degradation by an enzyme known as propyl hydroxylase; under hypoxic conditions, propyl hydroxylase gets deactivated thus leading to the stabilization of HIF-1α. As mentioned before, HIF-1α expression is triggered by hypoxic states, this crippling condition will aggravate the pro-inflammatory characteristics of HIF-1α. The vast majority of decompensated COVID19 cases manifest with drastic lung injury and severe viral pneumonia, the infection-induced hypoxia will the existing hypoxia in obesity. This will additionally augment HIF-1α levels that will provoke the already existing cytokines' storm to fulminant. Consequently, this will directly correlate the effect of a hypoxic environment with the increase of HIF-1α level. HIFɑ exists in two main isoforms HIF-1α and HIF-2α. HIF-1α and HIF-2α act in distinct ways in how they work on different target genes. For example, HIF-2α may act on hemopoietin genes (heme-regulating genes); while HIF-1α acts on EPO. HIF-1α release seems to be markedly augmented in obesity due to adipose tissue hypoxia and obstructive sleep apnea resulting in cyclic hypoxia. HIF-1α can also be secreted by direct viral proteolytic effects. Whereas, HIF-2α is stimulated by chronic hypoxia. HIF-1α exerts detrimental effects on the immune system, characterized by unopposed pro-inflammation at the macrophages, dendritic cells, T cells, and complement levels resulting in cytokines' storm, which is linked to the poor outcomes of COVID-19. On the other hand, HIF-2α role is regulatory and largely opposes the actions mediated by HIF-1α. In view of this, inhibiting HIF-1α release or switching its production to HIF-2α by natural products such as resveratrol or by synthetic drugs, offer a good therapeutic strategy that can prevent COVID-19 worst outcome in infected patients. The approach of breaking the vicious circle between lung damage-induced hypoxia and HIF-1α pro-inflammatory stimulant through drugs is considered to be extremely promising as a therapeutic manner to combat further deterioration of COVID19 cases.

Abstract
INTRODUCTION Pelvic lymph nodes move independently to the prostate. When delivering radiotherapy to prostate and pelvic lymph nodes, daily inter- and intra-fraction anatomical changes need to be accounted for. Planning target volume (PTV) margins, grown from the pelvic lymph node clinical target volume need to be determined, to account for this variation in position. METHODS Twenty patients who had daily online image guided radiotherapy to prostate and pelvic lymph nodes between April and December 2018 were selected. Ten pre-treatment verification images using cone beam CT from each patient were registered to pelvic bone anatomy, prostate soft tissue or fiducial markers and pelvic lymph node soft tissue to assess the accuracy of treatment delivery. Population systematic and random errors and PTV margins were calculated. RESULTS PTV margins of 0.4 cm, 0.4 cm and 0.7 cm left-right (LR), superior-inferior (SI) and anterior-posterior (AP) respectively were derived for the pelvic lymph nodes when registering to prostate. PTV margins of 0.3 cm, 0.2 cm and 0.4 cm LR, SI and AP respectively were derived for the pelvic lymph nodes when registering to bone. There was a posterior systematic shift of the prostate during the treatment course. CONCLUSION There is differential motion of pelvic lymph nodes to prostate and in the era of prostate and pelvic radiotherapy for patients with node positive prostate cancer; there is increasing importance in the accuracy of dose delivery to the involved lymph node. Hence, this group of patients may benefit from personalised radiotherapy PTV margins, especially if the involved pelvic lymph node is within the anterior part of the clinical target volume. IMPLICATIONS FOR PRACTICE Optimisation of dose delivery to the pelvic lymph nodes when prioritising the prostate in prostate and pelvic lymph node image guided radiotherapy.

Abstract
Doping is considered to be the main method for improving the thermoelectric performance of layered sodium cobaltate (Na1-x CoO2). However, in the vast majority of past reports, the equilibrium location of the dopant in the Na1-x CoO2' complex layered lattice has not been confidently identified. Consequently, a universal strategy for choosing a suitable dopant for enhancing Na1-x CoO2's figure of merit is yet to be established. Here, by examining the formation energy of Gd and Yb dopants in Na0.75CoO2 and Na0.50CoO2, we demonstrate that in an oxygen poor environment, Gd and Yb dopants reside in the Na layer while in an oxygen rich environment these dopants replace a Co in CoO2 layer. When at Na layer, Gd and Yb dopants reduce the carrier concentration via electron-hole recombination, simultaneously increasing the Seebeck coefficient (S) and reducing electric conductivity (σ). Na site doping, however, improves the thermoelectric power factor (PF), only in Na0.50CoO2. When replacing a Co, these dopants reduce S and PF. The results demonstrate how thermoelectric performance critically depends on the synthesis environment that must be fine-tuned for achieving any thermoelectric enhancement.

Abstract
Nowadays, the development of modern optical systems relies on optical device size minimization and operating power reduction. Optical modulator based on silicon on insulator (SOI) platform is a key element in different optical systems. Therefore, the optical modulator with compact size and low insertion loss could improve the optical system efficiency. In this work, a novel compact optical modulator based on hybrid plasmonic/silicon layers is introduced. The full vectorial finite element method (FV-FEM) is used to numerically analyze the proposed design. Vanadium dioxide (VO2) is also utilized as a cap layer to control the modulation process. The insertion loss (IL) and extinction ratio (ER) of the suggested modulator are equal to 2.1 dB/µm and 28 dB/µm, respectively, at the operating wavelength 1.55 µm. Consequently, high figure-of-merit (FoM) =ER/IL = 13.5 is achieved with an optical bandwidth (ER > 3 dB) greater than 1 µm, which is large in comparison to pervious designs.

Abstract
BACKGROUND Raqqa Governorate, Syria has recently been affected by overlapping conflicts related to the Syrian Civil war and occupation by ISIS, resulting in widespread displacement and disruption of economic livelihoods. However, little information is currently known about mental health needs and risk factors among women. Therefore, this study sought to examine potential risk factors for depressive symptoms among married women living in northern Syria. METHODS Data were collected between March and April 2018 as part of an evaluation of an International Rescue Committee cash transfer program targeted toward vulnerable households. Using cross-sectional data from 214 married women participating in the program, linear regression models were generated to explore the associations between depressive symptoms [nine-item Patient Health Questionnaire (PHQ-9)] and its potential risk factors, including food insecurity, perceived deprivation of basic needs [the Humanitarian Emergency Settings Perceived Needs Scale (HESPER) scale], and past-3-month intimate partner violence (IPV). RESULTS The average depressive symptom score was 10.5 (s.d.: 4.9; range: 2-27). In the final adjusted model, any form of recent IPV (β = 2.25; 95% CI 0.92-3.57; p = 0.001), severe food insecurity (β = 1.62; 95% CI 0.27-2.96; p = 0.02) and perceived needs (β = 0.38; 95% CI 0.18-0.57; p = 0.0002) were associated with an increase in depressive symptoms. CONCLUSION Study findings point to the need to address the mental health needs of women in conflict-affected areas of Syria. Programming to address risk factors for depression, including IPV and other factors associated with daily stressors such as food insecurity and deprivation of basic needs, may be effective in reducing depression in this population.

Abstract
BACKGROUND A significant gap exists between demand and supply of organs for patients with end-stage renal disease. To increase the donor pool, kidney transplantation is performed across ABO- and HLA-incompatible barriers. ABO-incompatible kidney transplant (ABOi-KT) recipients are at increased risk of antibody-mediated rejection, infection, and mortality. Hypogammaglobulinemia secondary to immunosuppression is highly prevalent after solid organ transplantation, and intravenous immunoglobulin (IVIG) has been reported to reduce the risks of infections in various settings. We use high-dose IVIG in ABOi-KT recipients perioperatively. We aimed to determine the rate of infectious complications along with graft and patient survival in our ABOi-KT recipients. METHODS We included all adult patients who underwent ABOi-KT from the year 2007 to 2016. Patients received rituximab, plasma exchange, and IVIG (2 g/kg body weight). Thymoglobulin and intravenous methylprednisolone were used as induction treatment. Oral prednisone, mycophenolate mofetil, and tacrolimus were used as maintenance therapy. RESULTS A total of 77 ABOi-KTs were performed, and the recipients were followed up for a median of 1557 days. Two patients were diagnosed as having BK nephropathy. No patients were diagnosed as having pneumocystis infection, cytomegalovirus disease, herpes simplex, varicella zoster, or fungal infection. One-year graft and patient survival was 94.8% and 100%, respectively. CONCLUSIONS In our series of ABOi-KTs, we observed a low risk of infectious complications and excellent patient survival. High-dose IVIG might have reduced infections.
