DEVELOPMENTS IN THE USE OF THERMOLUMINESCENCE AND OPTICALLY STIMULATED LUMINESCENCE FROM MOBILE PHONES IN EMERGENCY DOSIMETRY.

Proposed physical dosimetry methods for emergency dosimetry in radiological, mass-casualty incidents include both thermoluminescence (TL) and optically stimulated luminescence (OSL). Potential materials that could feasibly be used for TL and OSL dosimetry include clothing, shoes and personal accessories. However, the most popular target of study has been personal electronics, especially different components from smartphones. Smartphones have been a focus because they are widely available and, in principle, may be viewed as surrogates for commercial TL or OSL dosimeters. The components of smartphones that have been studied include surface mount devices (such as resistors, capacitors and inductors) and glass materials, including front protective glass, display glass and (with more modern devices) back protective glass. This paper reviews the most recent developments in the use of TL and OSL with these materials and guides the way to future, and urgently needed, research.

A survey analysis of knowledge levels of urologists about radiation safety and fluoroscopy use.

To evaluate the awareness of the use of fluoroscopy in endourological procedures, as well as the theoretical and practical applications of preventive measures. Between May 2018 and April 2019, a 26-question survey prepared using Google Docs was sent to urologists via email. Personal information, radiation training and behaviours related to radiation and fluoroscopy usage, and the use of protective equipment were queried. A total of 226 participants fully completed and returned the email survey. Of the 226 participants, 78 (34.5%) were academics, 44 (19.4%) were residents while 104 (46.1%) were experts. More than 60% of the participants stated that they participated in the operation requiring less than five fluoroscopy use per week. The majority of operations requiring fluoroscopy consisted of endourological procedures. The lead apron was used by 93% of the participants, but the use of protective glasses and gloves was very low (3.5%). The majority of academicians, experts and residents did not use dosimeters (76.9%, 82.7% and 81.8%, respectively). More than 50% of the participants did not have literature information about the harmful effects of radiation with the use of fluoroscopy. The most common complaints on the day of fluoroscopy were fatigue and headache. The lack of information regarding the radiation protection measures and harmful effects of radiation is common among urologists in Turkey. Therefore, systematic training programs on fluoroscopy use and radiation exposure should be provided during urology residency.

Ocular trauma secondary to exercise resistance bands during the COVID-19 pandemic.

ObjectiveTo characterize injuries caused by exercise resistance bands.MethodSingle-site retrospective case series of patients presenting to the Bascom Palmer Eye Institute emergency room with ocular injuries secondary to exercise resistance bands from March through September 2020.ResultsEleven patients (9 males, 2 females, 14 eyes) were reviewed. Eight patients had a unilateral injury (3 right eyes, 5 left eyes) while 3 had bilateral injuries. Iritis was the most common presentation, seen in all 11 patients, followed by hyphema (9 patients, 82%), and vitreous hemorrhage (4 patients, 36%). Among affected eyes, the mean presenting visual acuity was approximately 20/100, improving to 20/40 on the last follow up (p = 0.06). However, 4 eyes (33%) had vision ≤20/60 at last follow up.ConclusionsExercise resistance bands can cause a wide spectrum of ocular injuries, some leading to long-term vision loss. As such, we recommend that patients strongly consider using eye protection goggles or glasses while using resistance bands for exercise.

Effects of structural inhomogeneities on the steel balls resistance to loading

When conducting impact tests of protective glasses, nonunique cases of destruction of balls made of bearing steel ShKh15 were recorded. The causes of their destruction were determined. The state of the material was studied by fractographic and metallographic analysis, hardness and microhardness measurement. In the structure of the metal of all the balls, no critical defects were found such as flockens, shells and microcracks, but adverse factors were detected in the microstructure of the material, namely, the presence of fineneedle martensite with excessive carbides. It is established that the detected structural factors lead to liability to brittle fracture, an increase in the hardness of the material, a decrease in plasticity. To prevent brittle fracture of the balls and provide a reserve of plasticity of steel ShKh15 at high shock loads assessment calculations of ductility coefficient were made; and it was recommended to limit the maximum hardness of the material critical value HV=5.70 HPa (54 HRC), with the corresponding plasticity coefficient equal to 0.8.

The Use of Red Protective Filter Glasses as a Method of Preventing the Development and Progression of Retinopathy of Prematurity

The quality of newborns’ health, especially premature babies has the particular importance in the context of declining fertility. Retinopathy of prematurity (ROP) is a severe vasoproliferative disease affecting the immature vascular system of the retina in premature infants. This is one of the main reasons leading to irreversible vision loss in young children now. Since 2012, based on the State budgetary institution of Rostov region “Regional children’s clinical hospital” organized active screening, diagnosis and treatment of ROP. Since 2016, based on this institution, as well as the Perinatal center of the Rostov region, measures for the prevention of retinopathy of prematurity using red protective filter glasses have been applied. In 2016, the effectiveness of surgical laser treatment was 89 %, due to the increased number of children with aggressive posterior ROP and lightning-fast course of the disease and the lack of preventive measures in most departments of nursing premature babies. In 2017, the effectiveness of surgical laser treatment was 88 %, the relative decrease was due to an increase in the threshold stages. In 2018, the operational effectiveness of laser treatment was 93 %, because of the timely surgical treatment, to improve the quality of nursing preterm infants, active application of measures of prevention with the use of red filter protective in many branches the care of premature infants. The use of red filter protective glasses is a simple and affordable method of preventing retinopathy of prematurity, which reduces the need for surgical laser treatment and the number of adverse outcomes of the disease.

Lysing Yeast Cells for Immunoprecipitation Using a Coffee Grinder

This protocol describes the freezing of yeast in liquid nitrogen (LN2) to form small "beans" that can be ground using a simple propeller-blade coffee grinder. The method is ideally suited for lysate preparations from larger yeast cultures ranging from 50 mL to 5 L and displays the advantage that samples remain cold during the preparative steps. Cells are cultured and collected by centrifugation while in log phase, and the resultant cell pellets are mixed with deionized distilled water and dropped into LN2 to form small frozen beans. Before the freezing process, it is imperative to keep all cell pellets at 4°C on ice. The frozen yeast beans are ground by using a simple kitchen coffee grinder, and the yeast powder is collected for immediate lysis or storage at -80°C for subsequent use. Protective clothing and safety glasses should be worn at all times when working with liquid nitrogen. Plasticware may shatter upon repeated cooling in liquid nitrogen, and appropriate care should be taken.

COVID-19 pandemic and dental hygienists in Italy: a questionnaire survey

ObjectiveThis online cross-sectional survey assesses the signs/symptoms, the protective measures taken and the awareness and risk perception regarding COVID-19 among Italian dental hygienists. All Italian dental hygienists were invited to participate. The ad hoc online questionnaire was divided into four domains: personal data, protective measures (−before patient arrival; −in the waiting room; −in the operating room) and PPE, awareness and risk perception.ResultsTwo-thousand-seven-hundred-ninety-eight subjects participated. Only 0.25% of the sample was positive to the virus. Sense of fatigue (8.19%), headache (7.81%) and sore throat (7.32%) were the most common symptoms. A statistically significant trend across the areas with a different prevalence of COVID-19 was observed related to the number of signs/symptoms (areas z = 6.38 p < 0.01). Overall, 90.55% of the sample used protective glasses or visor, 90.10% disposable gloves and 82.80% surgical mask. Regarding the confidence to avoid the infection, a statistically significant difference was found among dental hygienists belonging to the 3 years-professional-experiences groups who worked in the high COVID-19 prevalence area. The findings of this survey show that Italian dental hygienists have modified their working habits according to the professional risk related to the current pandemic and they seem correctly prepared to face the risk of a SARS-CoV-2 infection.

Effect of protective glasses on radiation dose to eye lenses during whole breast irradiation.

ObjectivesThe efficacy of radiotherapy for breast cancer has greatly improved owing to better irradiation methods. Radiotherapy aims to deliver therapeutic doses to predetermined target volumes while sparing surrounding healthy tissues. However, there are few reports on radiation exposure to eye lenses, and the recommended exposure limits to ocular lens have been substantially reduced in recent years. This study aimed to investigate the amount of radiation exposure to eye lenses using optically stimulated luminescence dosimeters (OSLDs) and determine whether wearing special protective devices to protect the eyes, as an organ at risk, during whole breast irradiation, is necessary.MethodsThis experiment used OSLDs on water‐equivalent phantom to measure the change in scattered radiation dose due to the difference of irradiation field while using 4‐ and 6‐MV photons of TrueBeam linear accelerator. Using a total treatment dose of 50 Gy, a target was positioned to approximate the breast, and a plan was formulated to deliver 2 Gy per treatment by tangential irradiation. The mean (SD) irradiation dose at the lens position outside the irradiation field was reported.ResultsThe scattered radiation dose outside the irradiation field was more affected by the irradiation field size than by the radiation energy. The out‐of‐field irradiation dose with a larger field of view was higher than that with a smaller field of view. The use of 0.07‐ and 0.83‐mm‐thick lead shield protective glasses reduced the radiation dose by 56.1% (P < .001) and 55.6% (P < .001), respectively.ConclusionsIn this experimental model, the amount of radiation the eye was exposed to during whole breast irradiation was determined by the distance of the eye from the radiation field edge and by wearing protective glasses. In clinical practice, the protection offered by eyeglasses may reduce the risk of long‐term side effects and allow the use of higher intensive radiotherapy.

COVID-19 pandemic and personal protective equipment: Evaluation of equipment comfort and user attitude

This study aimed to evaluate the comfort of personal protective equipment (PPE) used during the COVID-19 and attitudes of healthcare professionals regarding the use of PPE. Descriptive research was conducted with 553 healthcare professionals, who work in pandemic centers in Turkey. Findings showed that all participants used masks, 99.3% wore gloves, 89% wore protective glasses, and 89% wore aprons during the COVID-19. The most-reported physical complaints have been dryness, irritation, and wound on the hands. Age and gender, as well as PPE discomfort, has been determined to affect the use of PPE. It might be concluded that age and sex, as well as the discomfort caused by PPE, affected the use of PPE and the attitudes of healthcare professionals.

PREVALENCE OF DRY EYE IN PREMENOPAUSAL AND POSTMENOPAUSAL WOMEN: A HOSPITAL BASED COMPARATIVE STUDY.

Objectives: This present study was to evaluate the prevalence and severity of dry eye with respect to age in premenopausal and postmenopausal women.&#x0D; Methods: Visual acuity was assessed on Snellen’s chart and anterior segment evaluation was done with slit lamp biomicroscope. Ocular surface Disease Index (OSDI) questionnaire was completed and grading done. Dry eye evaluation was done with Schirmer I, by placing a special filter paper in the lower fornix and Tear film Break-Up time was done by an impregnated fluorescein strip moistened with saline which was instilled into the lower fornix.&#x0D; Results: 64(32%), 42(21%) and 35(17.5%) women were belonged in age group of 61-70 years, &gt; 7o years and 51-60 years respectively. dry eye was seen in 6(6%) premenopausal and 47(47%) in postmenopausal women. Higher prevalence of dry eye 29(45.31%) was seen in age 61-70 years. 11(26.19%) prevalence was seen in age &gt; 70 years. Premenopausal women had mainly 6(100%) mild dry eye. 22(46.81%) Postmenopausal women had 22(46.81%), 14(29.79%) and 11(23.40%) mild, moderate and severe grade of dry eye respectively.&#x0D; Conclusions: Dry eye was commonly seen in older age postmenopausal women. Premenopausal women had mainly mild dry eye. Postmenopausal women had commonly mild to moderate grade of dry eye. Hence, early detection of dry eye is important to arrest the progression of dry eye as well as to prevent the complications that can reduce corneal transparency and reduce vision. Environmental and behavioural modifications such as taking breaks while reading, keeping the computer monitors at eye level, use of UV protective glasses and humidification of the environment can be tried.&#x0D; Keywords: Dry eye, premenopausal, postmenopausal, age group

Aim: In our study, it was aimed to determine the relationship between the use of personal protective equipment by healthcare workers in the COVID-19 epidemic and their depression, anxiety and stress levels. Material and Methods: 384 healthcare professionals working in a pandemic hospital participated in our descriptive study conducted in May 2020. The data collection tools; A form consisting of descriptive features, personal protective equipment use cases and Depression-Anxiety-Stress Scale (DASS-21) was used. The forms were delivered to healthcare professionals online and the responses were collected and analyzed in this way. Results: In our study, the Anxiety and Stress scores of female healthcare workers and the “DASS-21 anxiety score” of single healthcare workers were found to be statistically significantly higher (p=0.008; p=0.001; p=0.019; p 0.05). During COVID-19 pandemic, statistically significant differences were found between Depression Anxiety and Stress scores of healthcare workers according to their visor or goggles / protective glasses use(p<0.01; p<0.05; p<0.01). Similarly, the use of disposable gowns / overalls and similar equipment during the epidemic caused a statistically significant difference in “DASS-21 depression and stress scores” in healthcare workers (p=0.002; p<0.01; p=0.029; p<0.05). Conclusion: It was observed that depression, anxiety and stress conditions of healthcare workersworking intensively during the COVID-19 outbreak were affected. Suitable working environments and necessary protective equipment should be provided for healthcare professionals. With the planning for the development of mental health protection programs, it can be ensured that they overcome the intensive process with the least damage.

Investigation of dry eye symptoms of medical staffs working in hospital during 2019 novel coronavirus outbreak.

The aim of this study was to survey the prevalence of dry eye symptoms (DES) among doctors and nurses in the period of 2019, novel coronavirus (COVID-19) outbreak.To evaluate the DES of doctors and nurses worked at front-line hospitals with protective glasses for a mean time of 4 to 6 hours, a questionnaire developed by the researchers with the Ocular Surface Disease Index (OSDI) was used. These data were evaluated using descriptive statistics and correlation test with SPSS 22.0.The study included 13 doctors and 40 nurses, among which 16 were male and 37 were female, and the mean age of the participants was 32.43 ± 5.15 years old. According to the OSDI scores, 64.15, 24.52, 7.54, and 3.77% of the participants experienced occasional, mild, moderate, and severe DES, respectively. The factors significantly correlated with OSDI scores were age and duration of wearing protective glasses, while the duration of wearing protective glasses may be a protective factor of dry eye symptoms.Our study showed that most of the doctors and nurses worked at the front-line of combating COVID-19 did not experience DES, while the symptoms of those who experienced DES might be improved by wearing protective glasses.

Letter: Safety Instructions for Neurosurgeons During COVID-19 Pandemic Based on Recent Knowledge and Experience.

To the Editor: Here, we ask for the opinion of 4 worldwide-known neurosurgeons from 3 different continents and review the evidence from literature and from major relevant societies to provide a guide for the safety of surgical personnel and to reorganize neurosurgical practice during the COVID-19 pandemic and in the subsequent phase. Moreover, we retrieved relevant information from PubMed and from national and international organizations, including Robert-Hooke Institute, Germany, World Health Organization, German Society of Neurosurgery, and World Society of Virology, to develop guidelines. PROPOSED RECOMMENDATIONS FOR THE MANAGEMENT OF EMERGENCY NEUROSURGICAL PATIENTS DURING THE COVID-19 PANDEMIC All efforts should be utilized to perform certain emergency procedures under local anaesthesia. Endovascular treatment, if possible, especially in neurovascular diseases, should be considered as priority. Alternate treatment modalities, such as radiosurgery in certain neuro-oncological conditions, should be considered. To avoid any ethical issues, the urgent neurosurgical cases in all neurosurgical subspecialties should be triaged and treated. PROPOSED MANAGEMENT OF NEUROSURGICAL PATIENTS DURING COVID-19 WITH COVID-19 INFECTION All patients in emergency rooms (ERs) may be potential carriers of the virus and at least all unconscious patients should be treated as infected. Only 1 case from China and 1 from Japan with COVID-19 meningitis have been reported in the news. In literature, however, there is no single report on COVID-19 meningitis and the presence of virus in the cerebrospinal fluid. Moreover, some patients may present with neurological symptoms (eg, confusion) as the virus may cause hypoxia but still not provoke hyperventilation to compensate. Therefore, we still recommend the surgical personnel to take complete measures due to the presence of the virus in the blood. Urgent surgical procedures on COVID-19 positive patients should be performed only in dedicated operation rooms. To date there has been no single central nervous system complication reported that needed a neurosurgical procedure, but it is still highly possible that neurosurgical patients who need emergency surgery are COVID-19 positive with a high virus load. We propose the following safety measures for the surgeon and surgical staff during neurosurgical approaches. PROPOSED PRECAUTIONS DURING SURGICAL APPROACH During the pandemic, all neurosurgical procedures should be highly standardized to reduce the operation room time. Use of new materials or instruments and clinical studies should be postponed until the end of the pandemic. Whole surgical team should wear the FFP2/FFP3 (FPP stands for “Filtering Face Piece”) mask, eye protection glasses, double gloves, surgical suits, and shoe covers. Experienced neurosurgeons beyond their learning curve should perform the surgeries to reduce total exposure time. If possible, only a single surgeon should perform the surgery to avoid exposure to the assistant. Special care should be taken during craniotomy and drilling (irrigation with heat) to avoid aerosol dispersal and prevent them from reaching nose and eyes. Any dispersal of blood during drilling procedures should be avoided. Electrocautery power setting or the use of bipolar should be minimized to reduce aerosol dispersal. The surgical wound should be covered at the end of surgery. Special care should be taken and the powered air-purifying respirator (PAPR) mask should be worn during the endonasal surgery because COVID-19 is known for settling down in the nasopharyngeal room. SARS-CoV-2 negative (negative history of COVID-19, negative swab (2 times within 24 h) OR negative CT chest: FFP3 mask and safety glasses should be worn. SARS-CoV-2 positive: PAPR mask should be worn. Disclosures The authors have no personal, financial, or institutional interest in any of the drugs, materials, or devices described in this article.

Improving performance of solar roof tiles by incorporating phase change material

There is an increasing interest in integrating photovoltaic cells in building components, such as roof tiles. However, conversion efficiency of photovoltaic cells is temperature-dependant and high temperature will reduce the conversion efficiency. This paper studies the performance of mortar roof tiles with integrated solar cells and protective glass. To control the temperature of the solar cells, a phase change material (PCM) at a concentration of 3 wt% was mixed into the mortar roof tiles. The influence of the PCM on the solar-to-electrical power generation is evaluated for the solar roof tiles, and life cycle cost analysis is performed to assess the economic feasibility. It is found that the electrical energy output from the solar roof tiles with PCM is about 4.1% higher than that of the counterpart without PCM in winter days, whereas the corresponding improvement is in the range of 2.2 – 4.3% in six summer days. The economical payback time of the solar roof tiles with PCM is found to be 5.7 years including the inverter cost. The use of PCM increases the initial cost of roof tiles by 1.2%; however, considering an overall improvement of 4.1% in the energy output, the payback time is estimated to be three months shorter than that of the counterpart without PCM. The study also confirms that the ambient conditions influence the overall power generation substantially because of the impact on the working temperature of the solar roof tiles.

Ocular trauma in counter insurgency and proxy war environment: Epidemiological study, 1992–2004

BackgroundTo analyze the epidemiology of hospitalized ocular injuries occurring in counter insurgency and proxy war environment in a forward area of northern India over a period of 13 years. MethodsRetrospective observational study of medical records was performed of 458 patients with ocular injuries primarily treated at zonal referral hospital of Indian Army between January 1992 and December 2004. ResultsA total of 559 eyes with ocular injuries were studied. The average age of the victims was 30 years. In 77% cases, injuries were sustained by army personnel and remaining by paramilitary forces. Of all cases, 86.5% cases were due to combat-related (militant action), of which 93.9% cases were caused by splinters from munitions. Among the eyes injured due to militant action, 60.36% were open globe injuries, 31.19% were closed globe injuries and 8.45% were isolated adnexal injuries. Among the eyes injured, 76.33% of the eyes with open globe injuries owing to militant action had perforating injuries, whereas in closed globe injuries, 47.74% eyes had corneal foreign body. Among eyes with open globe injuries, Corneo-scleral, scleral and corneal lacerations were seen in 45%, 28% and 27% eyes respectively. 15.75% of eyes with ocular injuries underwent eviscerations. ConclusionThe study reveals that splinter eye injuries from munitions were the most common cause of ocular morbidity in counter insurgency and proxy war. Implementation of use of protective glasses by the personnel deployed in such hostile environment and strict compliance of preventive measures would be effective in saving eyes and also medical and economic resources.

Multiple-factor model of hardness of steel 40H13 after laser processing

The multiple-factor experiment is planned and made, and the hardness of the chromic steel 40H13, which is subjected to laser processing on a multibeam laser complex, is determined. Samples in the form of a cylinder 7 mm long and with a diameter of 30 mm are exposed to laser processing. Hardness of the processed surface layer of samples was measured by means of the Micro-Combi Tester installation of CSM Instruments (Switzerland). The independent entrance factors of process, which significantly impact on operational indicators of the processed surface layer, are chosen: power of laser radiation, longitudinal feed of laser beam and a distance from protective glass of a focusing head up to the processed surface. As a result of performance of the plan of a multiple-factor experiment and statistical data processing of a planning matrix the regression equations, which connect the optimization parameter with independent factors, having the interactive and dominating impact on formation of physic-mechanical characteristics of quality of the processed surface layer are received. On the basis of the received multiple-factor model and its graphic interpretation the appointment and optimization of modes of the laser processing, which provides the required values of hardness of a surface layer, is possible.

Influence of laser treatment mode on the friction coefficient and wear of bearing steel

The article considers the influence of input factors of the laser processing: the radiation power, the longitudinal feed of the laser beam and the distance from the protective glass of the focusing head to the workpiece on the friction coefficient and absolute wear of steel SHH15SG. The greatest influence on the output parameters (friction coefficient and absolute wear) has the power of laser radiation, as it increases, the wear of the surface layer decreases. The obtained multi-factor models and graphical interpretation of the experiment results allow us to assign a laser treatment mode that provides the demanded wear of the treated surface layer of bearing steel. The developed method of assigning the laser processing mode reduces the auxiliary time of the technological operation and eliminates the need for additional experiments in production conditions. The results of the research are useful for manufacturing enterprises that implement laser processing processes, as well as for design organizations that develop modern laser equipment.

Oxidation protective glass coating for magnesium silicide based thermoelectrics

A Mg2Si–Mg2Sn based thermoelectric material (TE), with composition of Mg2Si0.487Sn0.5Sb0.013, produced by ball-milling combined with spark plasma sintering, is successfully coated with a new silica-based glass, which is specifically designed, characterised and tested as an oxidation protective coating for mid-temperature range (up to 500 °C) applications. Despite the relatively high coefficient of thermal expansion (CTE) of Mg2(Si,Sn) based materials, very good thermo-mechanical compatibility between the substrate and the coating material is obtained. Oxidation tests, performed at 500 °C for 120 h in air, demonstrate the effectiveness of the glass coating for the protection of Sb doped Mg2(Si,Sn) thermoelectric materials.

Mechanical and nuclear radiation shielding properties of different boro-tellurite glasses: a comprehensive investigation on large Bi2O3 concentration

In this study, the synergistic positive effect of Bi2O3 additive on protective glasses with high efficiency against gamma and neutron is underlined. Five different boro-tellurite glass samples coded as BTB40, BTB50, BTB60, BTB70, and BTB80 were produced. These glasses have been examined for their rigidity and radiation shielding properties. The mass attenuation coefficients (μm) of these glass samples in the energy range of 0.015 MeV to 15 MeV have been calculated comparatively with the MCNP simulation and XCOM theoretical program. Half Value Layer (HVL), Tenth Value Layer (TVL), Mean Free Path (MFP), Effective Atomic Number (Zeff), Energy Absorption Buildup Factors (EABF) at different penetration depths and Effective Removal section (ΣR) (for fast neutrons) known as important shielding parameters were calculated for boro-tellurite glass samples. Along with the nuclear radiation shielding parameters, several mechanical properties of the glass samples the longitudinal (L), shear (G), bulk (K), Young’s (Y) modulus were calculated with the help of Shear ultrasonic velocity (Vs) ultrasonic velocities, Longitudinal ultrasonic velocities (VL) and density (). Among the mentioned shielding parameters; low HVL, TVL, MFP, EABF and high μm, Zeff, ΣR values show that the glass material has good shielding properties. According to the results obtained, BTB80 glass sample with the highest Bi2O3 additive showed excellent nuclear radiation shielding and elastic properties among other glass samples.
